An similar maneuver is performed at the medial side using the more distal hole and avoid ing damage to the suture material already in place. The lateral sutures are tied strong in slightly flexed stifle position and outward rotation of the extremity. Small animal orthopedic and neurosurgery page 29 Proximal tibia corrective osteotomy techniques for the repair of the cranial cruciate deficient stifle P. The treatment of cranial cruciate deficient stifle has been influenced by the introduction of biomecanical concepts. The treat ment has been more attentive on compensating the cause of the cranial cruciate rupture rather than replacing the loss of its function. It led to the development of new techniques, not only stabilizing the cranial drawer sign but also constraining the tibiofemoral shear force leading to cranial tibial thrust. The results of those repairs are improved when compared to the traditional ones, providing full function return with no or only little progression of postoperative arthrosis. Lack of objective data concerning this technique leads to controversy regarding the understand ing of its effects, the preoperative planning and the type of technique to be used. The surgical corrections pointed out here are feasible on any size of dogs, with readily available instruments and implants. A soft tissue technique during closure of the wound stabilizes the persisting cranial drawer sign of the tibia, to avoid later meniscal damage. Preoperative planning Analysis of biomechanics of the hind limbs (figure 1) evidence the direction of the joint force of the stifle joint to be nearly parallel to the patellar ligament force. The joint force can be calcu lated from the joint reaction (compressive) force and the tibiofemoral shear force (figure 2). The tibiofemoral shear force and the quadriceps muscle main peak activity have been demonstrated to be maxi mal in the early stance phase in humans. It is the task of the anterior cruciate ligament to sta bilize the tibiofemoral shear force. The tibiofemoral shear force is neutralized if the tibial plateau is perpendicular to the force of the patellar ligament. Greatest divergence angle between these two forces is present on radio graphs of the stifle in extension. A line passing through both tibial in sertions of the cranial and caudal cruciate ligaments is traced, representing the orientation of the tibial plateau. A second line passing through the patellar insertion of the patellar ligament is Small animal orthopedic and neurosurgery page 30 traced perpendicularly to the line representing the tibial plateau. Surgical techniques Lateral approach to the stifle joint and lateral arthrotomy allows its exploration. Partially ruptured anterior cruciate ligament is left intact, removing only torn parts. The insertion of the cranial tibialis and peroneus longus muscles is elevated from the lateral fossa extensoria unto the sulcus extensorius. A parapatellar incision of the pes anserinus is extended to the middle of the tibia and elevated off the proximal aspect of the medial tibia. The lateral muscular structures are retracted caudally and a transverse pilot hole is drilled through the tibia, using oscillating mode. Its origin is located at the distal insertion of the me dial collateral ligament of the stifle. It represents the basis of a wedge ostectomy situated be tween the bursa of the patellar ligament cranially and the cranial aspect of the sulcus exten sorius caudally (figure 5). A 10 template is helpful to first set landmarks in order to define the transversal wedge to be removed from the proximal tibia using the oscillating saw. First, the cranial osteotomy line is carried out monocortically and then completed toward laterally while sparring periarticular soft tissue structures. Overlapping of osteotomy lines has to be avoided to not create stress rising areas, which could generate later fracture of the tibia. Very slightly diverging osteotomy lines towards laterally are used to correct excessive tibial internal rotation. A Hohman retractor is placed along the caudal tibial cortex after partial elevation of the pop liteus muscle, to protect popliteal structures and vessels. Holes and a small cut with the saw are placed on the caudal aspect of the tibia, in order to weaken it, slightly proximal to the initial pilot hole. It is then possible to fracture the caudal tibial metaphysis towards cranially bringing it into contact with the tibial tuberosity, using bone-holding forceps. Severance of the fibula just below its head may help to respect the functional axes of the tibia during the leveling of the tibial plateau and maintain intimate contact between the two fragments. Two interfragmentary screws of minimal sizes are placed in position function into a craniocaudal direction in order to stabilize the osteotomy (figure 6). The first, distal screw is aimed perpen dicularly to the osteotomy line in a caudolateral direction. The second, proximal screw is parallel to the tibial plateau and to the medial cortex. Apneurotic sling: After copious flushing of the wound the fibrous joint capsule is closed in oppositional cruciate suture pattern. The medial and lateral fasciae of the stifle are prepared further proximally a round the femoral condyles and imbricated over the proximal cranial half of the tibia, with the Small animal orthopedic and neurosurgery page 31 help of preplaced horizontal mattress suture pattern. The proximal lateral fascia is imbricated over the patellar ligament with a far-near-far-near pattern (figure 7) Cranalization of the patellar ligament the insertion of the patellar ligament is advanced cranially by an open sagital osteotomy of the tibial tuberosity (figure 4). After performing a medial arthrotomy, the medial meniscus is in spected for its integrity. An oscillating saw is used to perform a sagital incomplete osteotomy preserving the insertion of the patellar ligament. The incomplete osteotomy is secured distally using a hemicerclage wire (figure 9). A bone expander wedge (tricalciumphosphate) of adequate size is inserted at the osteotomy site to position the tibial tuberosity cranially. The repair is stabilized using a positive threaded single pin inserted through the tibial tuberosity, bone expander, and into the proximal tibial metaphysis. After copious flushing of the wound the fibrous joint capsule is closed in appositional cruciate suture pattern. Closure Facial incisions, subcutaneous layers and skin are then closed in appositional fashion. Postoperative radiographs are made and a soft Robert-Jones bandage is applied over the limb during the first two days. The activity of the dog is restricted with a leash until the first radio logical control, 4 6 weeks after the surgery. The gait was functional and the operated stifles stable upon palpation 4 to 6 weeks after the surgery. Partial cruciate rupture did not evolve and arthrosis appeared minimal at later controls (1 year or more). A clinical study on 100 consecutive surgeries revealed that 87% of operated dogs returned to full function of the oper ated limb 4 months after the surgery. Small animal orthopedic and neurosurgery page 32 Fig 1 Fig 2 Fig 4 Fig 3 Small animal orthopedic and neurosurgery page 33 Fig 5 Fig 6 Fig 7 Fig 8 Fig 9 Small animal orthopedic and neurosurgery page 34 Arthroscopy in the dog Daniel M. Although the long term medical efficacy and cost efficiency has yet to be determined, it is clear that arthroscopy provides both superior joint visualization and decreased patient morbidity when compared to open surgery. Perhaps the strongest indication for the use of arthroscopy is in the management of developmental skeletal disorders and osteoarthritis. In addition, while a defini tive protocol for the treatment of osteoarthritis remains elusive, it is likely that future manage ment of this disease will involve both medical and arthroscopic techniques.

It is important to examine the fetal face and skull during prenatal ultrasound examinations because abnormalities of these structures may indicate the presence of other, more subtle anomalies, syndromes, chromosomal abnormalities, or even rarer conditions, such as infections or metabolic disorders. The prenatal diagnosis of craniofacial abnormalities remains diffcult, especially in the frst trimester. A systematic approach to the fetal Received: May 29, 2018 skull and face can increase the detection rate. When an abnormality is found, it is important Revised: June 30, 2018 Accepted: July 3, 2018 to perform a detailed scan to determine its severity and search for additional abnormalities. Invasive prenatal diagnostic Elizabeth Hospital, Gascoigne Road, techniques are indicated to exclude chromosomal abnormalities. In particular, the prevalence of facial clefts and commercial use, distribution, and reproduction in any medium, provided the original work is properly craniosynostosis is around 0. Whenever a craniofacial abnormality is found, it is important to perform a detailed scan to screen for additional anomalies. Further investigations, including invasive prenatal diagnostic techniques, may be indicated for chromosomal studies or molecular testing. The prenatal diagnosis of some abnormalities, such as craniosynostosis, remains 2019 Jan;38(1):13-24. Nonetheless, over-diagnosis should be avoided because structures are examined [10]. The skull has an oval shape and most fetuses with isolated brachycephaly or dolichocephaly continuous echogenic structure interrupted only by narrow have normal outcomes. The main purpose of this review is to provide up-to-date information on prenatal sonography of craniofacial abnormalities, with the goal of increasing diagnostic accuracy. H Skull the size, shape, integrity, and bone density of the skull can be assessed when the head size is measured and when the brain Table 1.

Neither do we have any explanation why there was no correlation with the immunohistochemical scores. It may be possible that the scoring systems are too crude in comparison to the more sensitive T2 values. Studies have shown that thin fibers appear yellow to green, while thicker fibers polarize in a longer wavelength, showing an orange to red appearance. However not only fiber thickness but also fiber organization and package plays an important role. Dense packed and well-aligned collagen fibers also polarize in a longer wavelength (orange to red). An advantage of this method is, that also the structure of cartilage can be examined. Beside the polarization of the collagen fibers, fibrillation, fissures and erosions are also visible, providing additional information about cartilage health. Despite noting the differences in bifringence of the collagen fibers in our specimens, there was a tendency that the sections were predominated by the picrosirius red stain. This is probably attributed to the staining protocol used or more likely to a technical 32 error, because the protocol has been used previously and has not caused these types of artefacts. In our study the surface of a healthy articular cartilage always had a light brown staining on immunohistochemical sections. This could be the consequence of the normal wear and tear in the articular cartilage metabolism. Possibly the antibody could penetrate more when cartilage was degraded compared to normal cartilage leading to the inhomogenous staining. This presumption was confirmed by the fact that the immunohistochemistry score significantly correlated with the mean overall Mankin score. A future study scanning the actual osteochondral cores and then histologically processing them is planed to overcome this limitation. According to various studies, regional variations of cartilage T2 values are also affected by age, because ageing affects the collagen 38 matrix changes and reorganization. The effect of age on T2 relaxation times was not taken into the equation in this study, however should be considered when evaluating further hyaline cartilage using T2-mapping. We did not consider that T2 values have shown a spatial variation within the actual joint cartilage. In the human knee shorter T2 values were found in 15 the deep cartilage layer compared to the superficial ones. This finding may also be present in equine cartilage and should be kept in mind and may be subject to further cartilage segmentation studies. Where higher T2 values can be expected dorsally in the joint and low T2 values can be found in the joint center. A follow up study with more samples of severely diseased cartilage should be performed to test the sensitivity of the imaging sequence in equine hyaline cartilage before the technique can be reliably used in an equine research setting or in the future in a clinical setting.

Age dependency of cartilage magnetic resonance imaging T2 relaxation times in asymptomatic women. The changes in cartilage thickness within the joint are likely attributed to the different pressures the individual areas have to bear during loading and their adaptation to these loads. First it was determined that the T1 relaxation time decreased significantly following intraarticular gadolinium administration. The T1 values of normal cadaver cartilage ranged from 473 -732 ms and T1Gd values ranged from 182-330 ms. The median T2 values obtained for normal cartilage (32 ms) mildly to moderately diseased cartilage (32 ms) and severely diseased cartilage (35 ms) were similar to the T2 values obtained in human knees ranging from about 35 to 45 ms for the deep and superficial cartilage layers, respectively. Nevertheless T2 mapping is sensitive to changes in the collagen matrix and changes in water content and 60 water motion. We opted to assess the collagen architecture using polarized microscopy and picrosirius red staining. These degradation fragments can also be identified immunohistochemically, however this was not performed. On the other hand, if proven sensitive enough, T2 mapping would be a convenient sequence to use in live horses because scanning times are fast and there is no need for contrast application. However also this technique is not suitable for the low resolution of the standing low field units of today. The common limitation for all parts of these studies was the relatively low number of cadaver limbs used, which relates to the decision making of cost effectiveness between tissue sampling and power of experiments. Using an intravenous route in alive horses would be much easier than using the intraarticular approach. Using the normal scanning protocol used in our clinic we could not achieve a significant reduction (P = 0. We have to assume that not enough contrast media was taken-up by the cartilage, or by the time the scan was performed (after a median of 50 minutes) the contrast media was already washed out of the cartilage. For the use of intravenous contrast media the ideal time point of scanning first needs to be determined. In human medicine patients typically exercise lightly for 15 minutes following contrast administration and 109 images are obtained 45 to 90 minutes after intravenous contrast administration. Hence the contrast agent is administered intravenously whilst the horse is under general anaesthesia, and the joint cannot be flexed due to the positioning in the gantry nor can the horse be exercised. General anaesthesia may also influences the contrast agent uptake in the cartilage, because it is may change the blood circulation of the articular structures. Maybe if there is peripheral vasoconstriction during the anaesthesia, the concentration of contrast agent near the joint and the diffusion into the cartilage may be lower than in an awake or for sure lower than in an exercising horse. Five cases are not enough to draw any definitive conclusions, but we can assume that the metabolism of the cartilage, despite being slow, is different in cadaver specimens compared to live horses having an effect on the T1 relaxation times. Different T2 values for deep and superficial cartilage layers have been shown in the 70,94,110 human knee. Superficial cartilage was found to have significantly longer T2 values 70,63 compared to the deeper cartilage layer. Future studies should aim at differentiating superficial and deep cartilage layers. Further research needs to attempt to differentiate between the two cartilage layers in diseased limbs. In human knee cartilage T1 values also show spatial variations (low values at the 94 surface and higher values in deep tissue). The same stratification can be expected in equine cartilage for the T1 values and should be subject of future studies.

This administrative approach requires close coordination and unified policy statements. This resuscitation should be per formed according to the American Heart Association and American Academy of Pediatrics Neonatal Resuscitation Program. Care of neonates at high risk should be provided by appropriately qualified personnel. When an infant is maintained on a ventilator, these specialized personnel should be available on site to manage respiratory emergencies. If they are in a regional center, they should devote their time to providing and supervising patient care services, research, and teaching, and they should coordinate the services provided at their hospital with those provided at institutions delivering lower levels of care in the region or system. Personnel qualified to manage the care of mothers or neonates with complex or critical illnesses, including emergencies, should be in-house. Pediatric surgical and anesthesia capability should be available onsite or at a closely related institution for consultation and care. Evidence indicates that management of neonates and young children by adult subspecialists, rather than pediatric subspecialists, results in greater costs, longer hospital stays, and potentially greater morbidity. Intrapartum care requires the same labor intensiveness and expertise as any other intensive care and, accordingly, perinatal units should have the same adequately trained personnel and fiscal support. The scope of practice should be based on national nursing guidelines for the specialty area of practice and should be in accordance with state laws and regulations and the recommended staffing patterns for the particular type of health care provider. The health care provider-to-patient ratio should take into account the role expected at the individual unit, acuity of patients, procedures performed, and participation in deliveries or neonatal transport. A multidisciplinary committee, including representatives from hospital, medical, and nursing administrations, should follow published professional guidelines, consult state nurse practice acts and any accompanying regulations, identify the types and numbers of procedures performed in each unit, delineate the direct and indirect nursing care activities performed, and identify the activities that are to be performed by non-nursing personnel. Advanced Practice Registered Nurses Trends in neonatal and maternal care have resulted in the increased use of advanced practice registered nurses. An advanced practice registered nurse is prepared, according to nationally recognized stan dards, by the completion of an educational program of study and supervised practice beyond the level of basic nursing. Nationally recognized certification examinations exist for each category of 28 Guidelines for Perinatal Care advanced practice nursing. Credentialing is now required on a national level and is no longer governed by individual states. The clinical nurse specialist models expert nursing practice, participates in admin istrative functions within the hospital setting, serves as a consultant external to the unit, and applies and promotes evidence-based nursing practice. Similar to the clinical nurse specialist, a nurse practitioner also may be involved in education, admin istration, consultation, and research. The spectrum of duties performed by an advanced practice registered nurse will vary according to the institution and may be determined by state regulations. Each institution should develop a procedure for the initial granting and subsequent maintenance of privileges, ensuring that the proper professional credentials are in place. That procedure is best developed by the collaborative efforts of the nursing administration and the medical staff governing body. The number of staff and level of skill required are influenced by the scope of nursing practice and the degree of nursing responsibilities within an institu tion. For perinatal care, it is recommended that there be an on-duty regis tered nurse whose responsibilities include the organization and supervision of antepartum, intrapartum, and neonatal nursing services. The presence of one or more registered nurses or licensed practical nurses with demonstrated knowledge and clinical competence in the nursing care of women, fetuses, and newborns during labor, delivery, and the postpartum and neonatal periods is suggested. Ancillary personnel, supervised by a registered nurse, may provide support to the patient and attend to her personal comfort. Intrapartum care should take place under the direct supervision of a reg istered nurse. A licensed practical nurse or nurse assis tant, supervised by a registered nurse, may provide support to the patient and attend to her personal comfort. This regis tered nurse should have training and experience in the recognition of normal and abnormal physical and emotional characteristics of the mother and her newborn. Again, a licensed practical nurse or nurse assistant, supervised by a registered nurse, may provide support to the mother and attend to her personal comfort in the postpartum period. This registered nurse should have demonstrated expertise in obstetric care, neonatal care, or both. A registered nurse with advanced training and experience in routine obstetric care and high-risk obstetric care should be assigned to the labor, deliv ery, and recovery unit at all times. All nurses caring for ill newborns must possess demonstrated knowledge in the observation and treatment of newborns, including cardiorespiratory monitoring. The neonatal nurse at this level cares for premature or term newborns who are ill or injured from complications at birth. The neonatal nurse provides the newborn with frequent observation and monitoring and should be able to monitor and maintain the stability of cardio pulmonary, neurologic, metabolic, and thermal functions, either independently or in conjunction with the physician; assist with special procedures, such as lumbar puncture, endotracheal intubation, and umbilical vessel catheterization; and perform emergency resuscitation. In units where neonates receive mechanical ventilation, medical, nursing, or respiratory therapy staff with demonstrated ability to intubate the trachea, manage assisted ventilation, and decompress a pneumothorax should be available continually. For antepartum care, a registered nurse should be responsible for the direc tion and supervision of nursing care. For intrapartum care, a registered nurse should be in attendance within the labor and delivery unit at all times. This registered nurse should be skilled in the recognition and nursing management of complications of labor and delivery. They also should be experienced in caring for unstable neonates with multiorgan system problems and in specialized care technology. The obstetric and neonatal areas may be staffed by a mix of professional and technical personnel. Physician assistants are educated and trained in programs accredited by the Accreditation Review Commission on Education for the Physician Assistant. The responsibilities of a physician assistant depend on the practice setting, education, and experience of the physician assistant, and on state laws and 34 Guidelines for Perinatal Care regulations. The need for other support personnel depends on the intensity and level of sophistication of the other support services provided. Additional medical social workers are required when there is a high volume of medical or psychosocial activity. These sessions should cover the diagnosis and management of perinatal emergencies, as well as the management of routine problems and family-centered care.

Cryotherapy has a vast scope of application in post-traumatic rehabilitation of inju red locomotor system and preparing of active professional sportsmen for exercises. Si gnificant component seems to be a decrease in the intensity of post-traumatic pain and edema, for which people during professional training are especially exposed, as well as subjective improvement in general condition and better exercise tolerance. Clinical applications of low temperatures of those lesions regressed just after single procedure and obtained improvement was usually persistent. Beneficial effect of cold on the course of injuries in muscles caused by protracted training was observed, among other, in research [23] that assessed an impact of im mersion in water at temperature of n15C on injured during strenuous exercises (inc luding 8 sets of 5 maximal flexions) elbow flexors. In 15 women (control group) no physiotherapy was applied, while in other 8 women limbs participating in exercises received local cryotherapy in form of water immersion lasting for 15 minutes each time, immediately after exercises and after each 12 hours (in total 7 exposures). The follo wing parameters were assessed: muscular expansibility, isometric strength of muscu lar spasm, degree of relaxation of elbow angle, intensity of local swelling (based on the measurement of arm circumference) and activity of creatine kinase. In both groups of women relevant measurements and analysis of biochemical tests, which were done on the third day after muscle exercises showed significant increase in pain sensitivity (tenderness) of muscles, increase in arm circumference, increase in activity of creatine kinase as well as decrease in strength of muscular spasm and degree of relaxation of elbow angle. In group of women who received cryotherapy higher level of relaxation of elbow angle and lower activity of creatine kinase was observed in comparison with the control group that did not receive any therapy. On the basis of obtained results it was observed that cryotherapy applied as cold water immersion results in decrease of stiffness and degree of muscle damage after strenuous overloading physical exercises, however, it does not affect tenderness and loss of muscular strength, that are typical of such physical activity. In eight treatment result was acknowledged as very good (90-100 scores), in five n good (80-89 scores) and in one n satisfactory (70-79 scores). Significant increase of the tolerance to a strenuous training was observed, among others, in research [5] which included a group of 24 sportsmen practicing professio nally martial arts (mean age 21. Sportsmen received 10 daily whole-body cryotherapy pro cedures lasting for 3 minutes in a cryogenic chamber at temperature ranging from n110C to n150C. Before beginning of procedures, then after the first, third, fifth and tenth procedure as well as on the tenth day after completion of exposure to the cold, sport smen filled in a questionnaire in which they rated pain occurrence and its intensity in 137 Cryotherapy joints and muscles, impact of procedures on the tolerance of training and intensity of post-traumatic swelling. Assessment rated by sportsmen was subjective in its charac ter and was related to each day listed in questionnaire. On the basis of questionnaire significant change in sportsmenis subjective feelings in consecutive days of exposure was observed. As to the tolerance to training, first three days of cryotherapy did not produce any results. On the fifth day a significant decrease in the tolerance was obse rved, while on the ninth day n a significant increase in the tolerance to overloading was noted, which was maintained in 75% of sportsmen also on the tenth day after procedure completion. Since the fifth day of procedure cycle gradual decrease in the intensity of pain in injured joints was observed, that was particularly noticeable in knee and hand joints and to lesser extent in brachial and elbow joints. Equally benefi cial results were achieved in decreasing swellings and chronic pain syndrome. More over, in the half of the sportsmen an improvement in mood on the tenth day after the cryotherapy cycle was observed. Indications for applying cryotherapy Clear assessment of therapeutic effectiveness of cryotherapy based on the Eviden ce-Based Medicine principle is difficult, mainly due to the character of cryotherapy procedures that virtually makes carrying out clinical research through double-blind trial impossible as well as wide diversity of applied therapeutic procedures and va gue description of the clinical material and methodology of researches in available li terature [40]. To sum up described above results of clinical researches related to treatment ap plication of low temperatures, it should be emphasized that, as the majority of authors agree, that whole-body cryotherapy has significantly higher therapeutic effectiveness in comparison with local procedures applied in the majority of analyzed diseases. Based on contemporary literature reports and authorsi own experience, the follo wing indications for cryotherapy should be considered, both as an independent method and a component of the complex rehabilitation [4,6,10,33,35,41,42,47,53,66,67,69, 88, 139,153, 159,161,163]: 1. Regardless of the classical cryotherapy using radiation cooling with cryogenic tem perature, in the clinical practice cold is also applied (although quite rarely) as cooling through conveyance of cold (convection) in order to decrease body temperature in the following clinical conditions accompanied by hyperthermia: iheatstroke, imalignanthyperpyrexia, ithyrotoxiccrisis, i infectious disease with fever reaction, i diseases of central nervous system with excessive heat production, iconditionwithimpairedphysicalthermoregulation and as various forms of cooling through conduction, conveyance and vaporization in form of compresses, poultices and cooling aerosols (described at the beginning of the chapter) used mainly in the treatment of overloading syndromes of locomotor system and intensified muscular tension [135, 163]. Contraindications for applying cryotherapy Although therapy using low temperature is a relatively safe method, we have to bear in mind these conditions in which using low temperature may produce adverse health results. During qualification of patients following parameters should be taken into acco unt: patientis age, existing diseases, nutritional status, efficiency of blood vessels, time of exposure to the cold and its intensity, drugs taken by patients, drinking alcohol, individual sensitivity to the cold effect. All those parameters determine possibility of safe application of cryogenic procedures and may be a reason for patientis disqualifi cation for cryotherapy procedures. According to the present knowledge, absolute contraindications for applying cry otherapy are 6,10,33,35,41,42,66,67,139,163]: 139 Cryotherapy icoldintolerance, icryoglobulinemia, icryofibrynogemia, iRaynaudisdisease, ithrombotic,embolicandinflammatorylesionsinthevenoussystem, isomediseasesofcentralnervoussystem, i neuropathies of sympathetic system, imentaldiseasesrestrictingcommunicationwithpatient, iclaustrophobia, itakingsomedrugs,particularlyneurolepticdrugsandalcohol, ihypothyroidism, ilocaldisordersofbloodsupply, iopenwoundsandulcerations, iadvancedstageofanemia, iorganism cachexyandhypothermia, ineoplasticdisease, iactivetuberculosis, iacutediseaseofrespiratorysystem, idiseasesofcardiovascularsystem including: nunstableanginaandadvancedstageofstableangina, n defects in valvular apparatus in form of semilunar aortic valve stenosis and mi tral valve stenosis, notherdiseasesofcardiacmuscleandvalvularapparatusinstageofcirculatoryfailure, ncardiacrhythm disorder,among them, sinus tachycardia above 100/minute, narterio-venousshuntsinlungs. Also obvious absolute counter indication is lack of conscious consent to apply cryotherapy procedures. Except for absolute contraindications, there also are relative contraindications [33,67,153]: iageabove65years, iexcessiveemotionalinstabilitythatisexpressed,amongothersinform ofhyper hidrosis. Significant issue from the perspective of contraindications is applying cryothera py in patients with implanted cardiostimulators. Due to asymmetric work of muscles in the shoulder girdle and nape there is also disorder in cervical spine statics. A serious therapeutic difficulty is the fact that the majority of physical therapy procedures are contraindicated in patients with imple mented cardiostimulator due to possible disturbance in proper function of electronic components in a stimulator, also including producing false stimulation. Clinical applications of low temperatures Research [111,112] proved full safety of applying local cryotherapy in patients at early phase after cardiostimulator implementation. Thus, presence of implemented cardiostimulator is not a contraindi cation for applying treatment with cold. At the same time, taking into account high therapeutic effectiveness of the method related to significant alleviation of pain intensity after a procedure and when follo wed by kinesitherapy also making easier return of physiological mobility in brachial joint, cryotherapy should be considered as a valuable alternative to pharmacological treatment in such patients. In recent years, some controversy has been risen in the literature and related to using cryotherapy in the treatment of diseases with etiology, where hypersensitivity to the cold. Raynaudis syndrome) plays a significant role and that are traditional contraindications for applying such method of treatment. In research [45] in fourteen patients with symptoms of Raynaudis syndrome accompanied by rheumatoid arthri tis, scleroderma and lupus erythematodes local cryotherapy was applied as adjuncti ve treatment of the mentioned diseases. After a cycle of procedures, in all the patients increase in joint mobility as well as temporary hand warming maintaining for almost all day were achieved. Moreover, in nine patients a significant lowering of hand ten derness was observed. At the beginning of therapy (25 day) in patients intensifica tion of pain occurred and then it suddenly disappeared. Further, a gradual improve ment of sensation in hands and their functional activity related to return of ability to do complicated manual activities was observed. In no patient complications or signifi cant side effects of cryotherapy were observed. As authorsi own experience and literature data show, whole-body cryotherapy is well tolerated by patients, including children and the elderly. The method was suc cessfully, without any complications, applied in 81-year old as well as in 12-year old patient [4,10,33,35,41,42,67,153]. During first days of procedure, there may occur slight aggravation of disease symp toms what is generally promising prognosis. Positive reaction of body to the cold, at the same time potential usefulness of cryotherapy in a certain patient, may usually be evaluated after some 10 procedures. When after 10 procedures there is no improve ment in patientis status (it happens only in ca. When qualification for treatment was carried out correctly and all the procedures are followed, particularly during cryotherapy, then complications occur very rarely. In single cases only surface frostbites caused by device failure or contamination of nitro gen used to cool cryochamber were observed. Sometimes, during first phase of cryotherapy cycle temporary pain intensification may occur, however, it should not be a reason for inter rupting treatment. Scheduling an individual rehabilitation programme for patients that is a continu ation of cryotherapy, it should be taken into account that for a dozen or so minutes after cryostimulation there is intense stiffness and disorder of position perception, among other in knee joints, what in case of intensive exercises performed immediately after procedure completion may cause injuries [149]. These regular features, Clinical Practice, Clinical Therapeutics, and Current Concepts, demonstrate how to diagnose and manage diseases, keep you up to date with the latest in clinical care, and highlight the best treatments and management options.

Several histologic patterns include papillary, vesicular, and glandular, including the endometroid-like pattern. Intracellular and extracellular hyaline droplets are present in most yolk sac tumors. Embryonal Carcinoma Embryonal carcinoma is a malignant germ cell tumor that may be found in the rst year of life. Embryonal carcinoma is a poorly differentiated malignant lesion composed of embryonal-appearing epithelial cells with characteristic large nucleoli (Figure 20. Ovarian Tumors of Childhood Ovarian tumors of childhood include: teratoma, yolk sac tumor, granuloma (theca cell tumor), Sertoli-Leydig cell tumor, dysgerminoma, and gonadoblas toma. Juvenile Granulosa Cell Tumor Juvenile granulosa cell tumor is the most common ovarian tumor, overall, Table 20. Microscopically, the tumor is composed of myxoid nerve trunks with waxy bundles of spindle-shaped cells. Fibromatosis/Myobromatosis Fibromatosis (juvenile or infantile desmoid bromatosis) is a benign, brous, connective tissue tumor that presents as a palpable mass in the fascia, skeletal muscle, or periosteum (Figure 20. Fibromatosis consists of a rm, light gray or white mass with a rubbery, whorled, cut surface. Fibromatoses tend to be smaller than brosarcomas, averaging 2 cm in greatest dimension. Fibromatoses are spindle cell neoplasms with moderate variation in cellularity and the amount of inter cellular collagen. The tumors stain positively with vimentin but do not react with desmin, S-100 protein, actin, or cytokeratin.

The tumor is composed of immature fat cells with varying degrees of differentiation that are separated by connective tissue septa and loose, grayish, myxoid areas. The presence of lipoblasts with a bubbly, vacuolated cytoplasm is a requisite for diagnosis. Typical primary sites are the adrenal gland, posterior mediastinum, or neck along the paraspinal region, in association with the distribution of sympathetic ganglia. Catecholamines are excreted in the urine, and neuron-specic enolase is present in the serum.

Clinically, these fractures most commonly present with hip pain after trauma, and the patient may be unable to bear weight. Advanced imaging is considered medically necessary when radiographs are nondiagnostic or not sufficient to establish a diagnosis and/or direct management. When advanced imaging is warranted, having radiographs available at the time of advanced imaging allows the radiologist to more appropriately protocol the study, as well as to determine which study will best assess the clinical and radiographic concerns. Brachial plexus mass Advanced imaging is considered medically necessary when the results of imaging are essential to establish a diagnosis and/or direct management. Radiographic findings are nonspecific, and radiographs may be normal in up to approximately 20% of cases. Radiographic changes including osteopenia, joint space narrowing, and degenerative changes may less commonly be present. Plain radiography provides limited information about the popliteal cyst, but may provide additional information on joint and bone abnormalities such as loose bodies in the cyst or the general findings of osteoarthritis and inflammatory arthritis. However, there are some radiographic findings that are characteristic of certain masses. Early surgery should be considered only when there is evidence of symptomatic suprascapular nerve compression. Imaging is not indicated in patients with full or limited movement and nontraumatic shoulder pain of less than 4 weeks duration. Imaging and surgical intervention should only be considered after conservative treatment has failed. All three modalities are more accurate in identifying full thickness tears than partial thickness tears. For ultrasound, based on 25 studies and 2774 shoulders, the sensitivity was 91% and specificity was 86%. In 60%-75% of cases, avascular necrosis is associated with sickle cell disease, steroid use, alcoholism, chemoradiation, or metabolic bone disease. Those findings are likely applicable to other joints as the disease process is similar. Both of these modalities can be useful in evaluating the extent of hemophilic pseudotumor. They tend to be more numerous and more uniform in size, shape, and distribution in primary synovial chondromatosis. When direct arthrography is done, a lesion is considered to be unstable if there is insinuation of contrast between the lesion and its parent bone. In more advanced disease, additional changes include subluxation, subchondral bone loss or fragmentation, sclerosis, osteophytosis, and intraarticular bone fragments. When imaging is needed, radiographs are the first-line modality and should include postero-anterior and lateral views. If the diagnosis remains in doubt after radiography, further imaging is indicated. Advanced imaging is considered medically necessary when imaging is required to guide management. Exclusion: this indication does not apply to preoperative evaluation for primary total knee arthroplasty for osteoarthritis. A large systematic review of 8 randomized control trials and 8 cohort studies concluded that patient-specific instrumentation does not improve the accuracy of alignment of the components in total knee replacement compared with conventional instrumentation. Osteoarthritis Osteoarthritis is a clinical diagnosis, and imaging is not required in patients with typical presentation of osteoarthritis. In adults over age 40 with usage-related knee pain, only short-lived morning stiffness, functional limitation, and one or more typical examination findings (crepitus, restricted movement, bony enlargement), a confident diagnosis of knee osteoarthritis can be made without a radiographic examination. However, a composite of joint space narrowing, osteophyte, sclerosis, and cysts increases the probability from 24% up to 89%. These lesions may reflect increased water, blood, or other fluid inside bone and may contribute to the causal pathway of pain, but should be considered incidental findings and should not be used to determine a final diagnosis or make decisions regarding surgery.

Noted physical therapist Gray Cook popularized this exercise to teach athletes how to separate the function of the hip extensors from the lumbar extensors. Most athletes are unaware of how little range of motion they possess in the hip joint when the range of motion in the lumbar spine is intentionally limited. You will realize quickly that the range of motion in this exercise is only two to three inches. The range of motion can be increased significantly by relaxing the grip on the opposite knee, but this defeats the purpose. By relaxing the hold on the leg, you simply substitute lumbar spine extension for hip extension. Hands-Free Cook Hip Lift 62 Designing Strength Training Programs and Facilities 63 Level 2 In the hands free version of the Cook hip Iift (figure 4. In this situation the glutes must contract while the opposite side psoas maintains an isometric contraction. Begin in a hook-lying position, and raise the hips to create a straight line from the knee through the hip to the shoulder. You must create and maintain this posture by using 63 Designing Strength Training Programs and Facilities 64 the glutes and hamstrings, not by extending the lumbar spine. Before attempting this exercise, it is important to learn the difference between hip movement and lumbar spine movement through an exercise such as the Cook hip lift. Most athletes who do not understand this distinction arch the back to attempt to extend the hip. Isometric Single-Leg Supine Bridge p 103 Functional Training for Sports Level 2 the single leg supine bridge takes the concepts learned through the quadruped draw-In, double leg bridge, and Cook hip lift and begins to progress to a higher level of function. At this point the exercise moves from a four-point stability base to a three-point stability base. As we discussed in the section on Quadruped exercises this change in base of support and stability will now begin to target the multifidus as a rotary stabilizer of the spine to a greater degree. To do the isometric single-leg supine bridge, begin in a hook lying position, draw-in the abdominals to stabilize, perform a double-leg bridge and then extend one leg. Maintain this single-leg position by pushing the heel down and squeezing the glute. Bridge With Alternate March Level 3 the next step in the progression is to add a small alternate march action to the isometric bridge. You simply 64 Designing Strength Training Programs and Facilities 65 alternate lifting one foot then the other off the ground. A yardstick across the crests of the hip bones acts as a level to remind you not to let the opposite hip drop when the foot is lifted. With this exercise the progression may better target the multifidus, due to the rotational stress applied to the spinal column as a result of moving from four support points (shoulders and feet) to three support points (shoulders and one foot). This is a transitional stability exercise that will greatly increase the level of difficulty. Push down through the heel and activate the glute on the same side as the supporting foot. The combination of reading the work of Shirley Sahrmann and looking at my athletes led me to understand that I needed greater emphasis on the global muscles. In simple terms, we had to go back to variations of crunches and reverse crunches. Initially we had moved away from these exercises because we felt that our athletes had become rectus dominant. As information continued to come to light about the functions of the transverse abdominus and internal oblique, we moved to a program of deep abdominal training focused primarily on the draw-in and stability exercises. Over time our athletes did little to no flexion and I believe that our posture actually became worse as a result. Currently I believe that each beginner core session should contain: 1) Quadruped exercise 2) Bridging 3) Shoulder to hip flexion crunches or curl-ups 4) Hip to shoulder flexion reverse crunch 5) Lateral stabilization side bridge In numbers one through four, progression should be one of difficulty. This is necessary to insure proper mobility of the lumbar spine and has a hidden benefit. Side bending (lateral flexion) produces opposite side vertebral rotation so a progression of lateral flexion exercises done after lateral stability is developed target both lateral flexors and rotational stabilizers. Shoulder to-hip trunk flexion targets the internal oblique while hips-to shoulder-flexion targets the external oblique. The division is not as much upper versus lower as internal versus external oblique. The origin of the external oblique from the rib cage allows it to work to tilt the pelvis posteriorly. The reverse crunch is probably more important to include as the external oblique does not have thoraco-lumbar insertion and as a result will be the more neglected muscle in a stabilization-oriented program. The interesting thing about the external oblique is that it creates posterior tilt of the pelvis (the reverse crunch is in fact a posterior tilt). Sahrmann then states that if the muscle causes posterior tilt it must also correct anterior tilt. Weak external obliques allow anterior tilt, anterior tilt allows the psoas to shorten, the short psoas inhibits the glutes, the weak glutes and tight psoas prevent hip extension. The result is lumbar extension substituted for hip extension and back and or anterior hip pain. The athlete or client is asked to push the stick up the knees or to pull the toes under the stick. In order to perform the following exercises the athlete or client must be able to produce flexion correctly. The beauty of any of the variations of the stick crunch is that it is simple to see if the execution is correct. The movement is begun with the stick over the knees with the hips at ninety degrees to the trunk. The first action is to tuck the chin and then to attempt to perform a crunch one vertebrae at a time. Many coaches or trainers would initially look at the stick crunch and find it to be no different than a conventional sit up. This is not a sequential flexion movement and will not target the internal oblique as directly as a sequential curl-up type action. In the stick crunch the directive is to attempt to sequentially push the stick to touch the toes while simultaneously drawing-in the abdominals. This is extremely difficult and it is very easy to see if the athlete or client is weak in this area. If they cannot get the stick to the feet they are deficient in internal oblique strength. The instruction is to try to bring the stick to the feet while bringing the shoulders to the knees. Advanced athletes will be able to get the stick over the feet as pictured 68 Designing Strength Training Programs and Facilities 69 Figure 4. This movement targets the external oblique and is again a sequential movement aimed at teaching the athlete or client to posteriorly tilt the pelvis. Most athletes or clients who perform this type of movement actually use a combination of momentum and hip flexor strength to mimic a similar action. To perform the movement place an exercise bench approximately one foot away from the wall. Lie on the back, holding the edge of the bench with the hips and knees flexed to ninety degrees. Attempt to pull the 69 Designing Strength Training Programs and Facilities 70 knees up toward the face, keeping the knees together. In order to do this the client will have to pull on the bench to get assistance from the upper body. Greater activity in the external oblique is seen with lat or serratus contractions (O. The knees must be pulled towards the face, the heels toward the butt, and the toes to the shin. This will activate the external oblique, hamstrings and anterior tibialis muscles.

If this is not possible, samples may remain as whole blood at room temperature for up to 48 hours. Samples received as whole blood after 48 hours from sample collection should be rejected. All samples that have been transported or stored at room temperature for longer than 72 hours should be rejected. Some assays are available on random access analysers which overcome the need to batch specimens. Overall the estimated median MoM shows a small positive bias, but is within 5% of target. Given the small sample size, any flag assigned to this marker should be interpreted with caution. The flag allocated may not be a reliable measure of performance due to low throughput. Enabling proportionate quality improvements whilst sustaining and developing expertise T21/T18/T13 screening is a specialist, complex and continually evolving area of work. A minimum laboratory throughput will enable this expertise to be concentrated and developed. The principle of a network screening service with a minimum of 2000 samples per test per year enables laboratories with a smaller throughput to maintain the ability to monitor performance whilst working in a consistent way to a set of common standards. It also allows capacity and capability building to develop proficiency and technical expertise in a safe and efficient way. Promoting efficiency A high throughput, particularly where technology in use requires batching of samples, means that laboratories will be able to meet recommended turnaround times for results; poor turnaround times could delay diagnosis and on-going management options. The workload required to effectively and efficiently run a small throughput laboratory is about the same as, if not more, than a laboratory with a larger throughout. The quality control procedures employed by the laboratory must be sufficiently rigorous to detect problems with the assays, not only on a day-to day basis but also to check problems like a gradual drift of results with time and changes that may occur when a new batch of reagents is brought into use. Significant shifts in population medians have been observed on occasions with the introduction of a new reagent batch, which can then impact on the risks reported if it is not anticipated and allowed for. Similar effects have been seen after analyser maintenance and vigilance is required at all times. The statistical analysis monitors the screening process at various levels: from the overall standardised screen positive rate at the top level to specific adjustments for ethnicity, smoking and other factors applied to individual biomarkers. Laboratories receive detailed information on serum analyte performance and a summary ultrasound report of the departments they support. The provider should also ensure that there are adequate numbers of appropriately trained staff in place to deliver the screening programme in line with best practice guidelines. This makes it easier for the public to compare the various tests and, crucially, to understand that some decisions are more complex than others. They help local screening services to identify potential problems so they can be put right and have led to changes in practice and implementation of measures to prevent errors occurring in the screening pathway. It is an actual or possible failure in the screening pathway and at the interface between screening and the next stage of care. Although the level of risk to an individual in an incident may be low, because of the large numbers of people offered screening, this may equate to a high corporate risk. It is important to ensure that there is a proportionate response based on an accurate investigation and assessment of the risk of harm. Due to the public interest in screening, the likelihood of adverse media coverage with resulting public concern is high even if no harm occurs. A screening laboratory must have an incident management policy in line with the screening managing safety incidents guidance. This guidance outlines how screening incidents should be reported and investigated. The escalation procedure within the host trust should be described and an up-to-date list of incidents and their associated investigation reports maintained. Local risk management policies require staff to assess the risk associated with laboratory processes and how they can be improved within the laboratory. One way is to prepare a risk assessment of the screening pathway in the laboratory to identify risks and review how they could be mitigated. A sample of amniotic fluid is aspirated with a syringe and sent for analysis to test for a range of chromosomal and inherited disorders. It contains substances and cells from the fetus, which can be removed by amniocentesis and examined.

The range of chromosomal and genetic conditions that can be detected is similar to those for amniocentesis. Cut-off level Screening tests divide people into a group at lower risk of the condition being screened for, and a group at higher risk who are then offered further investigations. The cut off level is a point defined by the programme and used to distinguish higher and lower chance. Detection rate the proportion of affected individuals with a positive screening result. This means they will find it harder than most people to understand and to learn new things. They may have communication challenges and difficulty managing some everyday tasks. Many health problems can be treated but unfortunately around 5% of babies will not live past their first birthday. False-negative result Screening tests divide people into lower and higher risk groups. Some people with a negative screening test result do actually have the condition being screened for. False-positive result Screening tests divide people into lower and higher risk groups. Some people with a positive screening test result do not actually have the condition being screened for. Fetal anomaly ultrasound scan A detailed ultrasound scan, sometimes called the mid-pregnancy or 20-week scan. It is a screening test offered to all pregnant women and is usually carried out between 18 and 21 weeks of pregnancy. Fetus In humans, the unborn child after the end of the eighth week of pregnancy to the 24th week of pregnancy. Gestational age the duration of an ongoing or completed pregnancy, measured from the first day of the last menstrual period (usually about two weeks longer than that measured from conception). Marker An identifiable physical location on a chromosome whose inheritance can be monitored.
