In clinical practice, these coefficients are used to calculate the effect of different fractionation schemes. In contrast, tissue with a low cell renewal has a good opportunity for repair between fractions of irradiation. Slowly proliferating cells with low fi/fi ratios are very sensitive to an increased dose per fraction [417]. However, there are concerns about high-grade genitourinary and rectal toxicity, and long-term side effects may not all be known yet [445-447]. Meticulous follow-up and documentation of outcome and late toxicity are mandatory. Respective studies largely include low to intermediate-risk patients and obtain very favourable results. Extended androgen suppression did not significantly improve ten-year rates of distant (both arms 6%), loco-regional (6% vs. Toxicity included Grade 3-4 neutropenia (27%) with neutropenic fever in 2%, but no toxicity-related death. The real impact of such an approach remains, so far, hypothetical, since no randomised trails are available. There is also a very sharp fall-off for proton beams beyond their deposition depth, meaning that critical normal tissues beyond this depth could be effectively spared. In contrast, photon beams continue to deposit energy until they leave the body, including an exit dose. This trial shows improved outcome with the higher dose, but it cannot be used as evidence for the superiority of proton therapy per se [411]. Meanwhile, proton therapy must be regarded as a promising, but experimental, alternative to photon-beam therapy. Low-dose rate brachytherapy uses radioactive seeds permanently implanted into the prostate. Outcome data are available from a number of large population cohorts with mature follow-up [482-489]. A significant correlation has been shown between the implanted dose and recurrence rates [490]. Toxicity was mainly due to urethral strictures and incontinence and great care should be taken during treatment planning. There were no differences in the rates of late bowel, urinary or sexual patient QoL over a ten-year follow-up period. Absolute risks over ten years are small (1-4%) but should be discussed with younger men in particular [499]. Radiotherapy should be given in combination with long-term androgen 1b deprivation therapy (two to three years). Other options such as photodynamic therapy, radiofrequency ablation and electroporation, among others are considered to be in the early phases of evaluation and will therefore not be discussed in this edition of the Guidelines. In addition, a relatively newer development is focal ablative therapy, whereby lesion-targeted ablation is undertaken in a precise, organ-sparing manner. It is important that patients with a life expectancy > 10 years should be fully informed that there are limited data on the long-term outcome for cancer control > 10 years and that this treatment modality is still considered as experimental. Overall, because of the high risk of bias across the studies, the findings for cancer-specific outcomes were considered inconclusive. High-intensity focused ultrasound is performed under general or spinal anaesthesia, with the patient lying in the lateral position. Potential candidates are patients with low-to-moderate risk as part of clinical trials. The patient should be informed about the lack of long-term outcome data at > 10 years (see Section 7. Data from 4,000 patients across 21 studies (including one non-randomised comparative study and 20 case series) were included. The effect of this has been to identify men at an earlier stage with smaller tumours that occupy only 5-10% of the prostate volume, with a greater propensity for unifocal or unilateral disease [515-517]. The main purpose of focal therapy is to ablate tumours selectively whilst limiting toxicity by sparing the neurovascular bundles, sphincter and urethra [518-520]. The overall quality of the evidence was low, due to the majority of studies being single-centre, non-comparative and retrospective in design, heterogeneity of definitions, approaches, follow-up strategies, outcomes, and duration of follow-up. Robust prospective trials reporting standardised outcomes [522] are needed before recommendations in support of focal therapy for routine clinical practice can be made. Prostate specific antigen nadir values after ablative therapies may have prognostic value. Current methods have shown that the mean value after surgical castration is 15 ng/dL [524]. This new definition is important as better results are repeatedly observed with lower testosterone levels compared to 50 ng/dL [525-527]. It is easily performed under local anaesthesia [528] and it is the quickest way to achieve a castration level, which is usually reached within less than twelve hours. Due to severe side effects, especially thromboembolic complications, even at lower doses [530, 531] these drugs are not considered as standard first-line treatment. The different products have practical differences that need to be considered in everyday practice, including the storage temperature, whether a drug is ready for immediate use or requires reconstitution, and whether a drug is given by subcutaneous or intramuscular injection. Although there is no formal direct comparison between the various compounds, they are considered to be equally effective [533] and comparable to orchiectomy [533, 534]. Concomitant therapy with an anti-androgen decreases the incidence of clinical flare, but does not completely remove the risk. The practical shortcoming of these compounds is the lack of a long-acting depot formulation with only monthly formulations being available. The standard dosage is 240 mg in the first month, followed by monthly injections of 80 mg. This is the sole action of non-steroidal anti androgens and leads to an unchanged or slightly elevated testosterone level. Conversely, steroidal anti androgens have progestational properties leading to central inhibition by crossing the blood-brain barrier. Non androgen pharmacological side effects differ between agents, with bicalutamide showing a more favourable safety and tolerability profile than flutamide and nilutamide [540]. Flutamide is a pro-drug, and the half-life of the active metabolite is five-six hours, allowing for a three times daily dose. The androgen pharmacological side-effects are mainly gynaecomastia (70%) and breast pain (68%). This has led to the development of two new compounds targeting the androgen axis: abiraterone acetate and enzalutamide. This compound must be used together with prednisone/prednisolone (2 x 5 mg) to prevent drug-induced hyperaldosteronism. In clinical trials, the number and location of bone metastases and the presence of visceral lesion are the prognostic factors most often used [547]. Anti-androgen therapy is usually continued for four weeks but neither the timing nor the duration of anti-androgen therapy are based on strong evidence. The evidence quality of the studies included in this review was rated as moderate. The five remaining trials included different patient groups, mainly locally advanced and metastatic patients relapsing. Out of 3,040 selected patients, only 1,535 were randomised based on the inclusion criteria set. The pre-specified non-inferiority limit was not achieved, and the results did not show a significant inferiority for any treatment arm. Testosterone recovery was observed in most studies [567] leading to intermittent castration. This, as well as the lack of any survival benefit in M1 patients, suggests that this modality must only be considered as an option in a well-informed patient bothered by significant side effects and willing to avoid them.

The two cardinal symptoms are progressive neurological deficits and intractable seizures, often in the form of epilepsia partialis continua and recurring epileptic status. Late onset presentations are characterized by a slower clinical course and less serve neurologic deficits. Several patients have presented with progressive neurologic decline without seizures.

Students will also have the opportunity to build on skills learned during the Essentials of the Profession course during sessions on clinical epidemiology and medical ethics. Throughout the first year, students learn communication, physical exam, and clinical reasoning skills in the Practice of Medicine course. Relationship to other new courses the Pathways curriculum organization acknowledges that core basic/population science knowledge and skills are needed prior to the principal clinical year, but that the richness of more advanced science is best suited to students who have already had clinical experience on the hospital inpatient services and in ambulatory clinics. The expectation is that, having lived in a clinical context for a year, students will return to be more engaged in learning advanced basic and population sciences that are now much more relevant and compelling to them. This volume was inspired by the clinical neurophysiology lecture series at Beth Israel Deaconess Medical Center and Rhode Island Hospital, where faculty and trainees at these renowned teaching hospitals participate in a lecture series over the course of the academic year. Much like the lecture series, the Clinical Neurophysiology Primer is designed to acquaint trainees with the essential elements of clinical neurophysiology. Each chapter in this four-part volume is written by leading and respected clinical neurophysiologists. Fellows engaged in neurophysiology training, those pursuing more focused training in those areas, and neurology residents will all find this volume to be an indispensable reference.

The Clinical Neurophysiology Primer aims to meet this need by providing a broad and intentionally basic treatment of the most central topics within clinical neurophysiology. Faculty and trainees at these and affiliated teaching hospitals participate in a series of lectures over the course of the academic year designed to acquaint trainees with the elements of clinical neurophysiology, supplementing their clinical experiences. We hope that this primer will prove valuable to others as a companion book intended for clinical neurophysiology fellows and neurology residents, to be used in conjunction with such a program of lectures. The first addresses background topics integral to, and shared by, all the disciplines within clinical neurophysiology. These treat such topics as basic electronics and the neural basis for the central and peripheral electrical potentials that we study in the laboratory. The last part covers topics in related fields of clinical neurophysiology: autonomic testing, evoked potentials, sleep studies, and their applications. Many of the contributing authors are faculty, or were trainees, at our fellowship programs. Each chapter has appended references or bibliographies that provide the reader with additional sources of information to expand upon the introductory materials covered here. Chapter lengths also vary considerably in size, in part related to the breadth of the material incorporated. Finally, each chapter ends with a set of questions and answers to aid trainees in gauging their mastery of the materials. We hope this primer will fulfill its intended role as a starting point for fellows engaged in clinical neurophysiology training, for those pursuing more focused training in areas within clinical neurophysiology, and for neurology residents aiming to acquire a basic understanding of these disciplines. Rutkove 13 Technical, Physiological, and Anatomic Considerations in Nerve Conduction Studies. Anand and David Chad 21 Neurophysiology of Neuromuscular Transmission and Its Disorders. Blum Summary A basic understanding of simple electronics is vital for the student of clinical neurophysiology to better understand how we begin to analyze neurobiological systems. The elements of basic circuits have relevant and tangible application to the way in which we model the behavior of neural systems in the laboratory. This chapter helps to define and assemble these varied circuit elements for the student. This base of understanding is then used to illustrate how simple electronic circuits can filter and amplify biological data. Attention is devoted to digital signal analysis because modern clinical neurophysiology increasingly relies on digital sampling for ease of data analysis and storage. Lastly, electrical safety issues are considered, particu larly as they apply to the clinical neurophysiology arena. Key Words: Amplifier; circuit element; digital conversion; electrical safety; electrode; electronic filter; montage. If a collec tion of charges, whether positive or negative, are unevenly distributed, there is an inherent drive for those charges to redistribute to achieve electrical neutrality. One joule is defined as the energy required to accelerate a 1-kg mass by 1 m/s2 over a distance of 1 m. Separated charges (that have not achieved electrical neutrality) are a form of stored or potential energy, and this energy will be expended as the charge separation is neutralized. Current (I) is simply some quantity of charge (Q) moving in some quan tity of time (t). Mathematically, this is expressed as: I = Q/t From: the Clinical Neurophysiology Primer Edited by: A. The current must travel through a medium that consists of other particles, and this medium may interfere with the efficient flow of charge; it presents resistance (R) to that flow. Thus, the current is not only affected by the applied potential but also by the amount of resistance in the conducting medium. Metals conduct very well because of their abundant free electrons and, thus, are termed conductors. Conversely, materials that lack free electrons to facilitate the flow of charge resist this flow, and are known as insulators. Although the flow of electricity is achieved through the movement of electrons, current is conventionally described to flow from the positive pole to the negative pole. Thus, the direc tion of current refers to the movement of positive rather than negative charge. Current may also be conveyed by ions (regardless of charge polarity) in a tissue or solution, as is the case in the conduction of muscle or nerve potentials. Resistors Under everyday conditions, current meets with some resistance to flow, much as friction opposes the movement of an object over a surface. Practically speaking, resistors are made from materials that do not easily allow the free movement of electrons, such as carbon. Very high resistance materials that are the most restrictive toward the movement of electrons, such as air, rubber, or glass, make the best insulators. The greater the distance that current must traverse through a resistive material, the more resistance to flow there will be.

Regular clinical examination and monitoring of serum bilirubin, albumin and coagulation profle (134) are necessary in persons with cirrhosis on interferon based treatment in order to detect decompensated disease. The treatment of such persons with interferon-containing regimens carries a higher risk of serious side-effects, and the use of haemopoietic factors is recommended in settings where these are available (132). Simeprevir and ombitasvir/paritaprevir/ritonavir/dasabuvir are not approved for use in patients with decompensated liver disease. Daclatasvir, ledipasvir and sofosbuvir have been studied in persons with decompensated cirrhosis and their use has been demonstrated to be both feasible and effective. However, a proportion of patients with decompensated liver disease will deteriorate on treatment and currently there are no pretreatment predictors to identify these patients. Therefore, treatment of patients with decompensated liver cirrhosis should be considered only in centres with the expertise to manage complications and ideally where access to liver transplantation is available. Compensated cirrhosis may also progress over time to decompensated cirrhosis associated with ascites, oesophageal and gastric varices, and eventually to liver failure, renal failure and sepsis, all of which are life threatening. The diagnosis of decompensated liver disease is based on both laboratory and clinical assessment, and therefore a careful medical examination of patients must be made before starting treatment. Sofosbuvir, which is used in many approved regimens, does not have the safety and effcacy data to support its use in these situations. Preliminary pharmacokinetic and clinical study data suggest that the use of ombitasvir/paritaprevir/ritonavir and dasabuvir is feasible and the early results suggest possible effcacy (236). Both ribavirin and pegylated interferon require dose adjustment in persons with renal failure. Pegylated interferon fi2a is cleared by the liver and pegylated interferon fi2b via the kidneys. While a theoretical accumulation of pegylated interferon fi2b could occur in persons on haemodialysis, no differences have been reported clinically (225, 227). The dose of ribavirin must also be decreased as the risk of anaemia-related adverse events is high. In persons with renal impairment receiving chronic haemodialysis, ribavirin may be administered at a dose of 200 mg daily or 200 mg every other day. Plasma ribavirin is removed by haemodialysis with an extraction ratio of approximately 50%. Telbivudine, in particular, may be associated with a higher risk of neuropathy if given with interferon containing regimens. Thus, women with childbearing potential should be counseled that they require effective contraception during treatment and for six months after completion of therapy. Interferon can induce pregnancy termination and ribavirin is associated with fetal abnormalities. These two medicines are thus contraindicated in pregnant women and those with childbearing potential unless effective contraception. Thus, treatment was often reserved for patients with advanced fbrosis and cirrhosis, for whom the risk of adverse events was outweighed by the potential benefts of a cure. Despite these developments, in most countries, treatment allocation will initially be very restricted because of the high price of medicines and lack of laboratories and health-care infrastructure. Therefore, a framework to help policy-makers decide whom to prioritize for treatment is important. Various principles have been proposed, including morally relevant values such as treating people equally, giving priority to the worst off and saving the most lives (248). Successful treatment is associated with reduced complications and liver-related morality (251, 252). It should be recognized that a small proportion of patients with decompensated cirrhosis appear to deteriorate during treatment. Clinical management of these patients is challenging, as it is diffcult to predict which patients will experience this deterioration. Treatment after liver transplantation Treatment of patients following liver transplantation improves the chances of long-term liver graft survival. Patients with type 2 diabetes and insulin resistance have an impaired response to interferon-based therapy (268). Fatigue is a common symptom, which in most cases does not preclude activities of daily living but does impact negatively on quality of life (269). However, a proportion develops evidence of end-organ damage such as renal disease, peripheral neuropathy, arthropathy, and peripheral and central nervous system vasculitis. Treatment with interferon is feasible; however, it can mimic the manifestations of cryoglobulinaemia (273, 274). Major barriers related to the management of interferon-based therapies in these institutions preclude adequate treatment, as does the high turnover and movement of incarcerated individuals with poor linkage to care. Shorter, more tolerable treatment regimens with less monitoring needs may help circumvent these issues. Improved education and strict universal precautions can drastically reduce the risk of nosocomial transmission among dialysis patients but still, particularly in resource-limited settings, this practice is not always optimally adhered to. Health-care workers Health-care workers with evidence of active viral replication (in the United States >104 genome equivalents/mL) are restricted from performing procedures prone to exposure (284). Successful treatment would therefore eliminate any risk of transmission to patients and increase the availability of health-care workers for more wide-ranging clinical activities. At present, many countries have poor documentation of the prevalence of infection; this is particularly the case in low-income countries. The Global policy report on the prevention and control of viral hepatitis, 2013 provides country-specifc information on policies and structures already in place to combat viral hepatitis (126). Building on these policies and structures will be necessary to increase the availability of treatment for those infected. Estimates of how many people are likely to be affected may be made by assessing populations at high risk as well as previously documented prevalence and incidence rates. Negotiation on drug costs is required and prioritization of particular groups, for example, patients with advanced liver disease (fiF2 disease or, in more constrained settings, F4) may be required. Integration of services, for example, diagnostic and treatment facilities, may help to minimize costs and is likely to facilitate treatment delivery. Task-shifting is the process of sharing clinical management responsibilities with trained personnel such as nurses, clinical offcers and pharmacists. Such personnel should have access to consultations with specialized team members as necessary and are likely to require training in order to facilitate adequate health-care delivery. Sourcing of medication and negotiation on pricing at a central level (using pooled procurement) may also minimize costs. Clinical and laboratory facilities for screening and monitoring patients on treatment are an essential component of health-care provision. Pharmacy facilities and drug storage space, including refrigeration space for interferon, should be included in the planning of new treatment centres. The registration of new drugs in individual Member States may be time consuming and will require adequate planning. Service delivery may be achieved more readily by providing standardized, simplifed treatment regimens at a population level. Service delivery should make use of simplifed operational guidelines, training materials and approaches to clinical decision-making, as well as limited formularies. Disease education, patient preparation for side-effects while on treatment, support and appropriate informed pre and post-test counselling are required. For treatment, standardized regimens should be used in combination with simplifed clinical decision-making tools and standardized monitoring. Minimum packages for care and treatment require to be formulated locally, and treatment and monitoring algorithms developed. Such algorithms should include information on when to start therapy, when to stop, follow up, side-effects and management fow sheets. Increased supervision of sites is likely to be important during the early stages of treatment roll-out. Such large price discrepancies and lack of access to affordable medicines increase the risk of product diversion from countries where treatment is less expensive to countries where it is more expensive. Pharmaceutical companies, national treatment programmes and private distributors thus implement what are called anti-diversion measures. Possible specifc measures include product packaging that is specifc to the treatment programme, different trade names, different colour of tablets and electronic tracking tools.

I am sure that the students both undergraduate and postgraduate, interns and general practitioners, all will be benefitted. Any constructive and healthy criticism to make this textbook more informative will be highly appreciated. I am highly thankful to my ex-students and colleagues Dr Rafiq Ahmad and Dr Qazi Imtiaz for their deep interest in the script and additions in the book. Mohammad Maqbool Suhail Maqbool Preface to the First Edition Though there are quite a few books on otorhinolaryngology now available in the country, omission of some important topics or common conditions is noticed in most of these books. As such, a student or a clinician feels handicapped and has to waste a lot of time in looking from book to book for a particular topic or information. A humble effort has been made to prepare a comprehensive Textbook of Ear, Nose and Throat Diseases which would provide all the necessary details and conception to the reader. I hope and pray that all the readers of this textbook, undergraduate and postgraduate students, academicians, and general practitioners will be benefitted. Majid, Dr Ghulam Jeelani and Dr Rafiq Ahmad for their constant interest and contribution to the text. I must particularly thank Shri Jitendar P Vij of M/s Jaypee Brothers Medical Publishers Pvt.

On the other hand, psychiatric evaluaton should be considered if there is a queston of actve suicidal ideaton. Psychosis on Interferon-Based Therapy A study of 43 out of 943 patents who experienced psychiatric symptoms on standard interferon included four patents with a psychotc disorder (delusions and hallucinatons). If you experience or have experienced any of these symptoms, be sure to let your healthcare providers know. You may be afraid or even ashamed to admit to your healthcare providers that you are experiencing these symptoms (or have previously experienced them while on or of drugs). You are not crazy, but you may be having side efects or symptoms that are very treatable. Remember, your healthcare providers can only help you with things they know you are experiencing. Chapter 21: Mental Health and Hepatitis C Section 2: Mental Health Issues During Interferon-Based Therapy Anxiety on Interferon-Based Therapy Very few studies have focused on the symptoms of anxiety with inteferon-based therapy. If you have experienced more severe anxiety than others on a chronic basis, or have ever been treated with psychiatric medicatons for anxiety or panic atacks, be sure to let your healthcare providers know. Together, you can consider restartng treatment for your anxiety before you begin your pegylated interferon plus ribavirin therapy. Hypothyroidism is a well-known, reversible cause of depression that is associated with weight gain, decreased energy, sleepiness, and physical and mental slowness. If symptoms are severe and do not respond to medicaton to control the hyperthyroidism, interferon therapy may need to be discontnued. If you start your treatment feeling in charge of yourself and with a commitment to complete therapy, you may feel more hope and pride as you complete each day of treatment closer to reaping the full benefts of these powerful medicatons. Seek out both formal treatment programs as well as 12-step programs such as Alcoholics Anonymous, Cocaine and Narcotcs Anonymous. Caring Ambassadors Hepatitis C Choices: 4th Edition if that would give you more support in your goal of sobriety. Set up both formal and informal sponsors you can call when you need to talk with someone about impulses to relapse. Consolidate your natural support networks by letng others who are close to you know what you are going through. And do all those things you already know are good for you and that your primary care providers have been telling you such as paying atenton to healthy nutriton, good sleep hygiene with regular hours, and some exercise. Preventve (Prophylactc) Antdepressant Medicaton In additon to treatng a current major depressive disorder, some people have recommended that antdepressant medicatons be started before interferon-based therapy begins in people who have a prior history of major depressive episodes. One trial using citalopram (Celexa) pretreatment in patents on pegylated interferon plus ribavirin with a psychiatric history found lower rates of depression in pretreated patents than in those who did not receive citalopram. If you have had a course of antdepressant medicaton and then relapsed with depression and required another course of antdepressants, you are at higher risk of relapse during interferon-based therapy. You should consider discussing going back on antdepressant medicaton with your psychiatrist before beginning interferon-based therapy. Or you may feel, as many people do, that you are already taking enough medicaton and because pegylated interferon plus ribavirin induced depression usually responds well to treatment, you may choose to wait and see how you feel during the treatment. Antdepressant and Mood Stabilizing Medicaton If you experience a major depressive disorder during pegylated interferon plus ribavirin treatment, almost all antdepressants have been reported to be efectve and tolerated as treatment. One study specifcally assessed citalopram (Celexa) in the treatment of depression among patents with chronic hepatts C. There are many case reports of antdepressants that have been successfully used in the treatment of major depressive disorders during interferon-based therapy. Chapter 21: Mental Health and Hepatitis C Section 2: Mental Health Issues During Interferon-Based Therapy Table 1. Valproic acid (Depakote), of partcular concern because of an occasional associaton with elevated liver enzymes, was not shown to elevate liver enzymes more in patents with chronic hepatts C than other psychiatric medicatons, specifcally antdepressants, lithium, and gabapentn. Ofen other medicatons are substtuted instead of using valproic acid to control psychiatric symptoms in such situatons. Another study70 reviews a number of competng concerns with mood stabilizers such as the lithium and carbamazepine (Tegretol). Olanzapine (Zyprexa) has been used safely to help with mood stabilizaton in chronic hepatts C patents with bipolar disorder. The biggest barrier to getng treatment for depression and bipolar mood disorders is likely to be not recognizing their symptoms early and not acknowledging these symptoms need treatment. Summary Combinaton therapy with pegylated interferon plus ribavirin has signifcantly improved response rates across all genotypes compared to standard interferon. But this therapy is stll associated with depression and physical side efects that can negatvely afect quality of life. Depression and other mood disorders are efectvely treated with standard antdepressant and mood stabilizing medicatons. If you have a prior history of psychiatric, alcohol or substance use disorders, you should consider getng psychiatric and/or substance treatment for stabilizaton before startng pegylated interferon plus ribavirin treatment. On the other hand, patents with psychiatric and substance used disorders should not automatcally be considered ineligible for pegylated interferon plus ribavirin treatment. You are likely feel beter about yourself and your treatment if you learn as much as you can about them, and contnue to discuss your experiences and concerns with your healthcare providers and your support system.

A combined antoxidant approach has been used in research conducted at the Integratve Medical Center of New 38 Mexico in Las Cruces, New Mexico. In additon to the supplements, partcipants were advised to eliminate alcohol, sugar, and cafeine, to decrease their meat intake to a few tmes weekly, to increase intake of purifed water to eight glasses daily, and to begin a modest exercise program. A phase I clinical trial of 47 patents with chronic hepatts C looked at changes in liver enzymes, viral load, and liver biopsy results while on a protocol of antoxidants. Oral daily doses of glycyrrhizin, schisandra, silymarin, ascorbic acid, lipoic acid, L-glutathione, and alfa-tocopherol were given for 20 weeks along with intravenous preparatons of glycyrrhizin, ascorbic acid, L-glutathione, and B-complex given twice weekly for the frst 10 weeks. Thirty-six percent of those in the study had an overall improvement in their liver biopsy results. Interestngly, those patents in the study who had not responded to previous trials with interferon/ribavirin did not show any improvement in liver biopsy results. While there is some indicaton that antoxidants may slow the progression of liver disease in hepatts C, this specifc antoxidant therapy cannot replace standard treatment as a means of eliminatng the hepatts C virus. However, the researchers suggest that the combinaton of antoxidants with antviral therapy might improve the overall response rate. Nutritional Supplements for Patients With Cirrhosis In chronic hepatts C infecton that has progressed to cirrhosis, one of the concerns is an increased risk for liver cancer. The chances of developing liver cancer are estmated to be about 2% to 7% over the frst 20 years of infecton. However, sustained viral clearance as a result of interferon-based therapy has been shown to reduce the risk of future development of liver cancer. Retnol (a form of vitamin A) and vitamin K2 may have a role in reducing the risk for development of liver cancer among those with cirrhosis. A small study of 40 women with viral hepatts cirrhosis evaluated the long-term risk of developing liver cancer between those taking 45 mg of vitamin K2 daily compared to those not taking supplemental vitamin K. The researchers found those taking vitamin K2 were signifcantly less likely to develop liver cancer compared to those who did not take supplemental vitamin K2. A large study of men (213 patents and 1,087 controls) examining the level of circulatng retnol with the risk of developing liver cancer found that higher levels of retnol (a specifc form of vitamin A) were associated with reduced risk for liver cancer. Interestngly, serum levels of alfa-carotene, beta-carotene, beta-cryptoxanthin, lutein, lycopene, zeaxanthin, alfa-, gamma-, and delta-tocopherols, and selenium were not found to independently afect the risk of liver cancer in this study. When the liver is no longer able to break down ammonia or efciently flter toxins from the intestnal tract, toxins build up that afect brain functon. Symptoms of hepatc encephalopathy include sleep problems, confusion, depression, and disorientaton. A study of 100 patents with hepatc encephalopathy found that treatment with the amino acid L-carnitne (2 grams twice daily) resulted in decreased levels of circulatng ammonia and improved brain functon. Antoxidant supplements may counteract the damage caused by increased free radical actvity in the body. Other nutrients such as glutamine are important in the producton of glutathione, an antoxidant used by the liver to break down toxins, drugs, and chemicals.

Your western doctor may not be able to provide you with guidance because he or she may not be familiar or experienced with these products. Making a decision about whether to use one or more of these products can be challenging. In additon, there is no way to be sure how any one person will react to a product. One of the most common complaints from western doctors about alternatve products is there are litle or no data to support their claims of efectveness. For the most part it is true that many alternatve products have not been adequately studied, but this situaton is beginning to change. Manufacturers of some alternatve products realize that in order to gain credibility in the western medical community, they need valid evidence that their products are safe and useful. Some of the most common products marketed to people with hepatts C are reviewed in this secton. The inclusion or exclusion of any product should not be considered to deny or afrm its existence or efectveness. The products we have selected are those people with hepatts C seem to be most aware of and therefore ask about most frequently. Ultmately, it is up to you to do whatever research is necessary to make an informed decision about whether to try a given product. This is especially important in deciding whether to take a product that has litle or no study data available. We also contacted the manufacturers of the products discussed to request informaton directly from them. Be sure to tell each of your healthcare providers about all the products you are taking.

Other than potatoes (which have a high glycemic load), most fruits and vegetables are low glycemic load foods. Most whole grains (including whole-grain breads and pastas, oatmeal, and brown rice) are medium glycemic load foods. And unsurprisingly, most highly processed foods (candy, sugar-loaded drinks, and white-four breads, cereals, and pastas) are high glycemic load foods. By avoiding the high-glycemic, nutrient-poor foods, those who are already living with chronic liver disease can signifcantly reduce the risk that they might also have to deal with other serious diseases such as heart disease and diabetes. In additon, they provide a great deal of the fber that is important for your health. Including a variety of vegetables and fruits in your diet every day is one of the most important things you can do for good health. Most experts recommend eatng 5 to 9 servings of fruits and vegetables every day, with the high end of that considered optmal. That makes fruits and vegetables an important area to emphasize for improving nutrient intake. Fresh fruits and vegetables, lightly steamed or sauteed vegetables, and fresh-squeezed fruit and vegetable juices (preferably made with a juicer that retains the nutrient-loaded pulp) are the most nutrient-rich choices in this group because there has been litle or no processing to degrade the nutrients. These fruit and vegetable optons contain all of the vitamins and minerals nature intended. Therefore, including fresh or lightly cooked fruits and vegetables in your daily diet can be a partcularly potent source of nutrients. Whether raw, steamed, sauteed, or cooked into soups or sauces, the greater the variety of vegetables you eat, the beter your chances of getng all the important nutrients you need. Fruit is also a far healthier snack food than the common sugar and salt-loaded varietes. Caring Ambassadors Hepatitis C Choices: 4th Edition Increasing your fruit and vegetable intake to optmal levels can seem impossible to some people, but it may not be as difcult as you think. To reach the recommended 2 to 4 servings of fruit, just think in terms of trying to eat 1 to 2 cups of fruit each day. One serving of vegetables equals 1 cup of raw vegetables or fi cup of cooked vegetables. To get your 3 to 5 servings of vegetables, think in terms of a mixture of raw and cooked vegetables that equals about 1 quart per day. Eatng the recommended amount of fruits and vegetables is not very difcult if you concentrate your food choices appropriately. Have a piece of fresh or stewed fruit as a dessert and for some of your between-meal snacks. Eat a couple of servings of vegetables with your main meal of the day, and include at least one or two other vegetable servings at another meal or as a snack. In the morning, saute a mixture of vegetables such as onions, spinach, mushrooms, tomatoes, and potatoes and str them into an omelet for a nutrient-loaded breakfast. Add a variety of vegetables to rice, barley, couscous or any other grains you are cooking. Vegetables cooked into soup count as a serving or two, depending on how many vegetables you put into the soup and how much of it you eat. Making up a big pot of hearty vegetable soup can help provide vegetables for a number of meals. You can eat the soup over several days or freeze individual portons to use when other vegetable preparaton feels too difcult. If you add beans, chicken, or fsh to your soup, you will also be getng lots of protein. For days when eatng seems like a difcult chore, getng good nutriton can be made easier by pureeing or blending soup in a blender or food processor so that it becomes an easily drinkable, liquid meal. You need protein to: y build and maintain cells y keep muscles and organs healthy y produce enzymes and hormones y make the hemoglobin that carries oxygen to your cells y maintain your immune system When your protein intake is too low to maintain your protein stores, the immune system cannot functon normally. Too litle protein can also result in weight loss, fatgue, and a decreased ability to respond to drug therapy. Researchers from the Harvard School of Public Health note that almost any reasonable diet will provide the daily protein requirement. If you want to get technical, the average adult needs about nine grams of protein for every twenty pounds of body weight. In fact, in an era where high-protein diets have been heavily promoted, the greater risk may be getng too much protein. As already discussed, this is a case where more is not necessarily beter, especially for those with advanced liver disease for whom processing too much protein may be harmful. If you have any of these concerns, it is best for a healthcare provider who knows the details of your health status to prescribe the exact amount of protein you need each day. In general, the best recommendaton is to eat moderate amounts of protein from a wide variety of foods each day. When making protein choices, it is important to remember that we require all of the amino acids necessary for the body to build the proteins it needs. The eight so-called essental amino acids are those the body cannot make on its own. The so-called non essental amino acids are those your body can manufacture for itself, provided it has the necessary materials. To manufacture non-essental amino acids, the body uses other amino acids, vitamins, minerals, and enzymes. If any of these are in short supply, even the non-essental amino acids may become defcient. Complete proteins are found in animal foods such as eggs, dairy products, meats, fsh, and poultry. Essental amino acids can also be obtained through complementary proteins created by combining grains, nuts, seeds, and legumes such as beans, peas, and nuts. However, building tssue from complementary proteins requires more energy than building it from complete proteins. Therefore, if you have already experienced muscle loss and/or your appette is low, it may be beter for you to concentrate on eatng animal foods that contain complete proteins. If cost is a concern, remember that including some combinaton of beans, peanut buter, peas, rice, corn, nuts, seeds, and other grains in your daily diet will give your body the protein it needs. Small amounts of animal proteins added to a mostly plant-based diet can ensure that such combinatons work without increasing the cost too much. Some good, concentrated sources of protein are: y eggs y poultry skinless to lower the fat content y fish preferably deep-water, cold-ocean varieties since these are less likely to contain the liver-stressing toxins that fish from polluted waters may have y complementary proteins found in mixed grain/nut/seed/bean combinations y lean meat Unless lactose intolerance is a problem, cheese and other dairy products can add to your protein intake. Adding things such as alfalfa sprouts, chickpeas or other beans, or sesame seeds to your salad or having beans as part of your meal can increase your protein intake substantally. Just be careful not to overdo on seeds or nuts since they also contain substantal amounts of fat. With a reasonable combinaton of such protein foods in your three daily meals and occasional snacks, you should easily be able to eat the amount of protein you need. The best fat choice is monounsaturated fat such as that found in extra-virgin, cold-processed olive oil (which is probably the best overall choice), as well as in canola oil, avocadoes, peanuts, cashews, almonds, and most other nuts;. Cold water fsh (such as wild salmon and sardines) contain the heart-healthy omega-3 faty acids that are another good kind of fat. Caring Ambassadors Hepatitis C Choices: 4th Edition Perhaps most important of all is to avoid the bad fats that are common in the North American diet.

The metabolic adaptation to the cold is connected with a longer time of maintaining or repeated oc currence of a brown fatty tissue. The change of a functional state of effectors leads to increase or decrease in heat loss through organism (effectors of physical thermoregulation) or to decrease or incre ase in speed metabolic heat generation in organism (effectors of chemical thermoregu lation) [153]. Effectors of physical thermoregulation Physiological effectors mechanisms securing organism against cooling, being part of physical thermoregulation, include constriction of peripheral blood vessels. Taking into account variable blood supply of body circumference in a process of thermal re gulation, there is a poikilothermal Nintegumenti and homoiothermal Nnucleusi. Con striction of integument vessels and its cooling is aimed at protection of thermal nuc leus against heat loss. In the course of this phenomenon, thermoregulation narrowing of blood vessels is accompanied by blood transfer to volume blood vessels that are located deeper, what leads to volume increase of a so-called central blood. Blood transfer from superficial veins to deep veins, which are in neighbourhood of arteries and have relatively high temperature, causes passing of heat to a cold vein blood. The similar function is also served by contrary beha viour of metabolism processes in both afore-mentioned structures. In Nintegumenti in hibition of metabolism processes speed takes place and in Nthermal nucleusi proces ses connected with heat generation intensify. Decrease in heat loss is also caused by decrease in a body surface by taking an adequate position (bending) which is connec ted with increase in muscles tension leading to intense of muscle work and secondary heat generation. Taking into account conditions that are in cryochambers, important defensive factor against excessive cold action is active motion causing increase in heat generation. In other (non medical) situations adequate changes of activity and beha viour counteract cooling [84]. Effectors of chemical thermoregulation Increase in muscles tension and muscular shiver observed in organisms, which are subject to influence of low temperatures lead to heat generation. Muscular spasms 35 Cryotherapy are very efficient method of heat generation and they are the basis of shivering thermo genesis. Intensification of this expensive, from energetic point of view, process depends on temperature of a surrounding and on a time of organism exposure to the cold. The basic energetic substrates for muscles work are definitely carbohydrates, however in conditions of low temperatures action, an important role of energy source for mu scular shiver may also be played by lipids. In low temperature of environment an activity of adrenergic system increases and many hormones are released: catecholamine, glucagon and triiodothyronine. These hormones, acting on tissues and organs of an organism (mainly brown fatty tissue and liver), may cause acceleration of their metabolism speed and increase of heat ge neration on a non-shivering way [98]. The characteristic feature of brown fatty tissue is a great number of mitochondria and rich sympathetic innervations. Noradrenaline released from nervous endings acts on adrenergic receptors of adipocyte of brown fatty tissues, trigerring a chain of meta bolic reactions. Non-shivering thermogenesis connected with heat generation as a re sult of processes taking place in brown fatty tissue occurs only in a presence of ther mogenine. Adaptation mechanisms to stressful cold action are more complex that in the case of heat influence. To maintain homeostasis in response to low temperature, bigger syn chronisation of systems is required, mainly circulatory and endocrine systems and also metabolic processes. In these conditions stimulation of both somatic and autono mous nervous system takes place. Increase in activity of sympathic and adrenal parts of autonomous nervous system leads to increase in secretion of catecholamines and stimulation of fi-adrenergic receptors. An important effect observed during cryotherapy procedures is reduction of meta bolism with approximately 50% leading to decrease of energy requirement of tissues and connected thereto requirement for oxygen. In homoiothermal organisms maintenance of a steady bodyis temperature deter mines optimum course of reactions and intermediate transformations of cells, which activity depends on a narrow range on cellsi temperature. Within a cell, operation of enzymes is mutually dependant and chemical reactions take place in chains cataly 36 2. Biological effects of the cold zed through series of enzymes, which are coupled with many different transforma tion chains [30]. Their mathematic exponents are previously mentioned laws of Arr henius and Vanit Hoff. They prove that logarithm of chemical reactions intensity is proportional to temperature changes. In practice, coefficient (Q10) is used specify ing a scope of metabolism change at a temperature change with 10fiC. It was shown that during a heart operation at infants with applying of a surface cooling, the valu es of coefficient (Q10) were between 1. These big personal changes may be explained by a different sensibility of organism to cooling which depends on genes expression [103]. Influence of low temperatures on a course of thermodynamic processes in skin n biophysical mechanism of thermoregulation Since recently n in relation to increase of interest in cryotherapy and due to tech nical possibilities n one has started to examine and describe phenomena taking place during whole-body and local cold therapy. In a research [35], in which in 16 healthy men and women a temperature of skin and muscles at a depth of 1, 2 and 3 cm below a skin surface before, during and 20 minutes after a completion of local applying of cold compresses was monitored, it was proved that penetration of cold to tissues cooled with using of a cold compress was relatively low: it referred only to a skin and subdermic tissues to a depth of approxi mately 2. After a completion of 20-minute cooling, changes in temperature of deeper tissues occurred n they were subjected to cooling with giving back heat to surface tissues. As an effect, 40 minutes after a completion of cooling surprising tem perature inversion occurred n surface tissues became warmer than deep tissues (the difference was approximately 1fiC). Heat given back to surface tissues by deep tissues allows for temperature restoring of previously cooled surface tissues with lowering of temperature in deeper layers in a way of intensive thermodynamic exchange. Despite the fact that short-term exposure to the cold does not lead to big tempera ture changes inside particular body cavities and temperature changes take place al most exclusively in external integuments of body (depending on a type of used me thod, this decrease may come even to 12fiC), cooling has significant influence on a course of metabolic processes and functioning of many organs and systems. All physical and chemical processes which take place in a living organism, to a bigger and smaller level, depend on a temperature. Temperature influences metabolic processes, transport, value of bioelectrical potentials, speed of chemical reactions and sustainability of biochemical compounds that come into existence in organism. The hi 37 Cryotherapy ghest organized organisms, including a human beings, are homoiothermal, because it secures operation (among others) of specialized nervous system. A human body inside n due to heat generated in metabolic processes in such or gans as liver, heart, kidneys, brain and muscles is characterized by constant tempera ture. It is accepted that the external integument, which protects body inside against variable temperature con ditions of a surrounding, may have a different thickness and temperature. The significant role in a heat transport in external inte gument of a body is performed by heat conductivity of particular skin layers and sub dermic tissues, which value depends on blood supply resulting out of extension of blood supply vessels. Heat conductivity together with other heat parameters of chosen biological tissues in vitro are presented in Table 2.

It is accepted that a body temperature inside is approximately 37fiC and external temperature on skinis surface depends on measurement location and may differ wi 38 2. Biological effects of the cold thin specified limits according to on external conditions. For instance a temperature of feet varies within 25fiCfi34fiC, of hands n 29fiCfi35fiC and of a head 34fiCfi35. The average external temperature on a skinis surface (Ts) may be specified tempe rature measurements executed in different places in compliance with the following em piric formula according to Pilawski [111]: Ts=0. In our own researches [25,26] we examined an influence of whole-body cryothe rapy on a temperature of body parts surfaces, which have the biggest role in creating an average temperature of a body surface, i. Thermographic image of particular areas of patientsi bodies prior to commence ment of cryotherapy procedure are presented in Figures 2, 3 and 4.
