Pathophysiologisch scheinen Autoantikorper gegen das Aortenendothel eine Rolle zu spielen (Arnaud et al. Aneuryma-Resektion) sollte Arterienwand zur Biopsie entnommen werden, da hier oft eine laborchemisch nicht erkennbare Vaskulitis nachweisbar ist, die dann die Indikation zur weiteren immunsuppressiven Therapie darstellt. Die Diagnose der Takayasu-Arteriitis kann auch ohne histologische Sicherung gestellt werden. Bei alteren Patienten kommt ein entsprechendes Bild allerdings auch bei fortgeschrittener Atherosklerose und im Rahmen der Riesenzellarteriitis der gro en Gefa e vor. Endovaskulare oder chirurgische Bypass-Verfahren konnen im Verlauf notwendig werden; die Ergebnisse revaskularisierender Verfahren sind besonders hinsichtlich der Restenoseraten uneinheitlich. Generelle Empfehlungen konnen hier nicht gegeben werden (Zusammenfassung bei Saadoun et al. Sie betrifft mittelgro e Arterien und geht mit kardiovaskularen und neurologischen Symptomen einher; im Verlauf ist auch eine Nierenbeteiligung moglich. In einem relevanten Teil der Falle besteht eine Assoziation mit einer Hepatitis-B oder -C Infektion. Neurologische Symptome treten bei beiden Formen, etwas haufiger aber bei der klassischen Form auf. Klinik In etwa 70 % der Falle besteht eine subakute schmerzhafte und mit deutlichen Paresen einhergehende Mononeuritis multiplex, in 50 % findet sich eine Muskel und Hautbeteiligung. Typischerweise bestehen in diesem Stadium gleichzeitig Symptome der systemischen Erkrankung mit Gewichtsabnahme, Myalgien, Abgeschlagenheit und subfebrilen Temperaturen. Fokale Symptome wie Hemiparesen, Epilepsien und Hirnnervenausfalle sind mit jeweils bis zu 10 % seltener. Das angiografische Bild der Vaskulitis mit Aneurysmen zeigt sich im Bereich der Nieren-, Mesenterial und hirnversorgenden Gefa. Die angiografischen Befunde konnen die Diagnose stutzen, sie muss jedoch histologisch gesichert werden (Niere, Haut, Nerv-Muskel). Klinik Es lassen sich eine limitierte nekrotisierende Granulomatose mit Befall nur der oberen Luftwege und die generalisierte Vaskulitis mit Befall von oberen und unteren Luftwegen sowie Nieren unterscheiden. Wenn es im Verlauf zur systemischen Vaskulitis kommt, ist das Kapillarstrombett der Lungen und Nieren in Form einer rapid progressiven Glomerulonephritis betroffen. Diese kann unbehandelt innerhalb von Tagen bis Monaten zum irreversiblen oligurischem Nierenversagen fuhren. Fruhsymptome der generalisierten oder systemischen Krankheitsphase sind zudem Arthralgien und Arthritiden sowie Allgemeinsymptome (Gewichtsverlust, Nachtschwei). Diagnostik 13 Leitlinien fur Diagnostik und Therapie in der Neurologie Richtungsweisend sind eine ausfuhrliche Anamnese und eine interdisziplinare klinische Diagnostik. Laborparameter inklusive der Akutphasenproteine sind in der Fruhphase oft nicht oder nur minimal verandert. Therapie Generelle Therapiestrategie Grundsatzlich erfolgt bei aktiver Erkrankung zunachst eine hoherpotente immunsuppressive Therapie, die mit hochdosierten Glukokortikoiden, in der Regel in Kombination mit Cyclophosphamid oder anderen Immunsuppressiva, durchgefuhrt wird. Wahrend dieser Phase der Remissionsinduktion wird die Dosis der Glukokortikoide sukzessive reduziert. Nach Erreichen einer Remission und Reduktion der Glukokortikoiddosis in den Bereich der Cushing Schwellendosis (7,5 mg Prednisolonaquivalent) kann die Cyclophosphamidtherapie beendet werden und es folgt eine Weiterbehandlung mit meist weniger aggressiven Substanzen. Zu den Nebenwirkungen gehoren schwere Infektionen, das sehr gro e Risiko sekundarer Tumoren (Blasenkarzinom, Lymphom) und die Ovarialinsuffizienz. Einen wirklichen Standard zur Ovarialprotektion gibt es nicht, da die Studienergebnisse uneinheitlich sind. Alternative Methoden sind die Kryokonservierung von Eizellen und die Autotransplantation von ovariellem Gewebe. In 49 % handelte es sich um Neudiagnosen, in 51 % lag ein rezidivierender Verlauf vor. Alle Kranken erhielten Prednison (1 mg/kg taglich) nach initialer Bolustherapie (1 g fur bis zu 3 Tage). Ein signifikanter Vorteil fur Rituximab zeigte sich bei den 100 Patienten mit rezidivierendem Verlauf (67 vs. Zudem erhielten auch die Patienten im Rituximab-Arm zunachst additiv 2 Zyklen Cyclophosphamid. Bezuglich der primaren Endpunkte anhaltende Remission 12 Monate nach Therapiebeginn (Rituximab 76 %, Kontrollarm 82 %) und schwere unerwunschte Ereignisse (Rituximab 42 %, Kontrollarm 36 %) wurden keine Unterschiede zwischen den Therapiearmen beobachtet. Zudem ist ihre Wirksamkeit bei der Remissionsinduktion und insbesondere der Effekt anderer Substanzen dieser Gruppe, z. Mehrere unkontrollierte Studien zeigten einen positiven Effekt von Infliximab bei sonst therapierefraktaren Patienten (Hellmich et al. Plasmapheresen verbessern bei Patienten mit schwerer Nierenbeteiligung (Serumkreatinin > 500 mmol/l) das renale Outcome (Jayne 2007). Geschlechtsunterschiede bestehen nicht; das mittlere Erkrankungsalter liegt bei 40 Jahren. In der Vorgeschichte findet sich meist eine allergische Diathese mit Rhinitis, asthmoider Bronchitis oder Asthma bronchiale. Diagnostischer Goldstandard ist die Histologie, wobei der Muskel-Nerv-Biopsie neben der Biopsie aus Nasenschleimhaut, Haut und Lunge eine wichtige Rolle zukommt. Diskutiert werden infektiose Trigger, autoimmun vermittelte Prozesse, prothrombotische Anomalien des Gerinnungssystems und eine genetische Pradisposition. Klinik und Diagnostik Remittierende aphthose Stomatitis mit oralen Ulzerationen, rezidivierende genitale Ulzerationen, Augenentzundungen (Uveitis) und Hautveranderungen sind Leitsymptome. Die oralen Ulzerationen liegen lediglich bei 3 % der Patienten nicht vor; sie treten typischerweise mindestens dreimal pro Jahr auf und heilen ohne Hinterlassung von Narben ab. Die genitalen Ulzerationen zeigen sich im Bereich von Skrotum oder Labien und hinterlassen Narben, nach denen im Intervall gesucht werden kann. Im Bereich der Augen finden sich eine anteriore oder posteriore Uveitis, Glaskorperinfiltrate oder eine retinale Vaskulitis. Zu den Hautveranderungen zahlen das Erythema nodosum, Pseudofollikulitiden oder papulopustulare Lasionen. Grundsatzlich ist die Behcet-Krankheit eine Multisystemerkrankung vaskulitischer Genese, bei der neben Haut/Schleimhauten und Augen die Gelenke (Mono oder Oligoarthritis), der Magen-Darm-Trakt (Schleimhautulzerationen im Ileum oder Zokum), die Lunge (Pulmonalarterienarteriitis) und die Aorta bzw. Extremitatengefa e (Thrombophlebitis, Arteriitis mit Entwicklung von Pseudoaneurysmen) betroffen sein konnen. Manifestation 5 Jahre nach Beginn der Schleimhaut-, Haut und Augenmanifestationen in der 3. Nach dem Verteilungsmuster werden der vaskulare und der parenchymatose Neuro-Behcet unterschieden. Beschrieben wurden auch eine mild ausgepragte chronische lymphozytare oder neutrophile Meningoenzephalitis und multifokale Nekrosen in Hirnstamm und Basalganglien (Kidd et al. Motorische Ausfalle mit spastischen Zeichen und Hirnstammsymptomen sowie mentale Auffalligkeiten in Form von Gedachtnis und Aufmerksamkeitsstorung sind Leitsymptome des parenchymatosen Neuro-Behcet (80 % aller Neuro-Behcet-Patienten). Diese Lasionen halten sich nicht an Gefa territorien und fuhren im Verlauf zu einer Hirnstammatrophie (Al Kawi et al. Seltener sind eine aseptische Meningitis und Patienten mit rein psychopathologischen Auffalligkeiten. Im Liquor zeigt mindestens die Halfte der Patienten eine Pleozytose und Eiwei vermehrung. Wahrend in 70 % der Falle ein pathologischer IgG-Index vorliegt, sind die oligoklonalen Banden oft nur vorubergehend positiv (Akman-Demir et al. Der vaskulare Neuro-Behcet (20 % der Gesamtgruppe) zeigt als Leitsymptom eine intrakranielle Hypertension. Hirninfarkte bei Ubergreifen der Entzundung auf die Arterien sind selten (Akman-Demir et al.

The afferent nerves starting from the spinal cord transmit the signals to the nucleus tractus solitarius [14]. The brain has not a particular location for the sense of the stimuli emerging cough and the signal is diffused in many locations producing inhibitory or enhancer activation. It is suggested that midbrain areas recorded to introduce hypersensitivity to pain stimuli are also engaged in the cough circuit. There are very important commonalities in this respect between chronic cough and chronic pain, and in addition between chronic cough and other conditions such as chronic itch and chronic breathlessness [15]. There is a lot of progress defining the mechanism of cough and new strategies of treatment mainly through blocking peripheral terminals of Broncho pulmonary vagal afferent nerves [15]. Thus medications for cough are divided to the central and peripheral ones acting in different parts of the reflux. However, their effectiveness is not confirmed by different studies despite by their overuse by the public. The lack of effectiveness is the yet unexplained stimuli to the peripheral receptors [11]. Antitussive Studies in adults Studies in children Antihistamines No = 2 (350 patients) No = 3 (363 patients) Berkowitz 1991; Terfenadine Sakchainanont 1990; clemastine 0.

Review of the Literature 903 Codeine is an alkaloid opioid used from ancient times for the inhibition of pain and cough. It acts on the opioid receptors of the central nervous system or through its sedative results [15]. It comes from the plant Papaver somniferum and its extract was distillated by the chemist Jean Robiquet in 1930. Its commercial use is combined with antihistamines, antipyretics, decongestants and expectorants and it is frequently given without prescription. However, a Cochrane library meta-analysis failed to conclude about its overall efficacy in acute and chronic cough [15]. Codeine has serious side effects such as respiratory depression, itching, rashes, angioedema, vomiting and ataxia. Its effectiveness regarding the amelioration of cough has not been confirmed in some patients. The drug is metabolized in the liver in morphine and the rate of metabolism is related to individualized factors. Although there have been published considerable side effects, codeine is available commercially without prescription. Other antitussives with central action are pentoxyverine, butamirate and gabapentin which is an old anticonvulsive drug possessing an effect to neuropathic pain [11]. All those medications although frequently used, their effectiveness is not established compared to placebo. However, gabapentin use is suggested as the best option for use in chronic idiopathic cough [7]. Perhaps dextromethorphan, an antitussive with central action, has a similar mechanism of action [7]. Dextromethorphan is considered the only medication effective for coughing using objective methods [2]. Although a derivative of morphine, it has less analgesic and sedative properties [3]. Some other antitussives with peripheral action are levodropropizine used in south Europe especially in Italy, dextromethorphan and expectorants used in Germany by 23% of patients, such as ambroxol (metabolite of bromoxine) and N-acetylcysteine. As antitussive drugs have been used many extracts from plants or animals such as hexidine from Helix pomatia in France, which combines an antibacterial function especially against pertussis or menthol from the plant Mentha arvensis [2]. Some studies of cough preparations have been shown to reduce cough symptoms, whereas others found no effect compared with placebo [16]. Our understanding of the underlying mechanism of the cough reflex leads to the production of a new generation of antitussives currently under clinical trials. Such medication work binding central or peripheral receptors of the neuronal circuits and will be the future against cough (Figure 1) [11,15]. Problems related to the use of those drugs are caused by the wide distribution of these receptors. Sodium channel blockers: these drugs block the transmission of stimuli through the vagal nerve and they have been used only in experimental models. Targeting peripheral and central neurons of the circuit of cough is the basis of those new treatments. In periphery, the nerve afferent signals, the duration of activation and the number of units activated determine the intensity of signals. The signalling can be also enhanced or inhibited by parallel neuronal circuits [11]. Regarding the opinion of the public, a survey using mobile telephones in 2012 showed that 84. Interestingly, most of the responders though that an antibiotic should be provided (1/3) [17]. Conclusion Cough is defined as acute or chronic which have a different etiology and they are combated by different medications. However, public frequently uses over the counter medications with controversial effectiveness due to the disturbing nature of the symptom. New treatments relative to our knowledge about the mechanism of cough are under investigation. American Journal of Physiology-Regulatory, Integrative and Comparative Physiology 300.

S Mechanisms IgE-mediated hypersensitivity (positive skin tests, specific serum IgE, leukocyte histamine release). Cross-reactivity among histamine H2 receptors antagonists exists (ranitidine/nizatidine). Use another H2 antagonist if necessary (after negative cutaneous testing and oral challenge). Drug eruption caused by ranitidine hypochloride (Zantac*) which showed a strong reac tion in a drug-induced lymphocyte stimulation test. Anaphylactic reaction to drugs commonly used for gastrointestinal system diseases 3 cases reports and review of the literature. Proton pump inhibitors are widely used in the treatment of peptic ulcer and gastroesopha geal diseases. Cross reactivity among proton pump inhibitors exists: Omeprazole/lansoprazole, Lansoprazole/rabeprazole, but not with other imidazoles. Hypersensitivity to lansoprazole and rabepra zole with tolerance to other proton pump inhibitors. Allergy to lansoprazole: study of cross-reactivity among proton pump inhi bitors. Severe erythrodermic reactions to the proton pump inhibitors ome prazole and lanzoprazole. Sulphapyridine is believed to be responsible for most of the hypersensitivity reac tions although the salicylate compound may also be implicated. S Risk factors Hypersensitivity syndrome: slow acetylator genotype (N-acetyltransferase 2), elderly black men, flu like illness within the previous 6 weeks. Blood dyscrasias, hepatitis and hepatic failure, serious skin reactions are reported more commonly in patients receiving sulfasalazine for rheumatoid arthritis rather than for inflammatory bowel disease. Two main hypotheses: stimulation of T cells by the drug leading to reactivation of herpes virus harbored in T cells. The virus-stimulated T cells show a substantial cross-reactivity with certain drugs; administration of the drug leads to expansion of these specific T cells, and this continues after ces sation of the drug due to persistence of viral antigens. Tissue cells produce high levels of interleukin-5 and eotaxin that result in a maculopapular rash with eosinophilia. Desensitization is a safe approach in mild hypersensitivity reactions, but is contra-indicated in patients with the hypersensitivity syndrome, blood dyscrasias or serious cutaneous reactions. For example, in adults, starting with 1 mg and doubling the dose each week: 1 mg, 2 mg, 4 mg, 8 mg, 10 mg, 20 mg, 40 mg, 80 mg, 100 mg, 200 mg, 400 mg, 800 mg, 1000 mg, 2000 mg.

S Risk factors Presence of cetuximab-specific IgE antibodies (specific for galactose-alpha-1. Papulopustular eruption: the most frequent side effect (60% to 80%), dose-dependant relationship, rapid onset after the initiation of treatment: 7 to 10 days or more; distribution in the seborrheic areas (face, scalp, upper back, shoulders and neck and behind the ears); acneiform eruption with follicular papules and pustules without comedons; pruritus and telangectasias may be associated; resolution after completion of the molecule or spontaneously despite the continued therapy: erup tion may be correlated to tumor response. Telangectasias with rosacea-like appearance of the face, xerosis, nail changes (paronychia with or without pyogenic granulomas), hair abnormalities, trichomegaly. These effects lead to inflammatory cell recruitment and sub sequent cutaneous injury. S Management Use of corticosteroids (dexamethasone or prednisone) prior to each dose of denileukin diftitox decreases the incidence of acute infusion events and vascular leak syndrome. Capillary leak syndrome in a patient treated with interleukin 2 fusion toxin for cuta neous T-cell lymphoma.

Alternatively, reactive aldehydes may activate T cells through Schiff base formation, a transient interaction between the carbonyl and amine groups in physiological systems (Rhodes et al. Some effects are seen in the lung, such as an increased number, but decreased functional ability. Among former smokers, however, disease risk is higher than among never smokers (odds ratio 1. Smokers also showed reduced severity of ulcerative colitis, as assessed by self-reported symptoms, hospitalizations, or medication use (Loftus, 2004). Vestergaard (2002) reported results from a meta-analysis of 25 studies pertaining to smoking history and Graves disease (hyper thyroidism), Graves disease with ophthalmopathy, and various forms of hypothyroidism. Current smoking was strongly associated with risk of developing Graves disease (odds ratio 3. One study showed an increasing risk with increasing number of cigarettes per day in current smokers. Nevertheless, there was some indication in the two studies that allowed sex-specific analyses that the association was stronger in women than in men. Stronger associations for never smokers and current smokers were seen with Graves disease with ophthalmopathy (for never smokers, the odds ratio was 4. The only study that presented sex-specific analyses reported a stronger effect in women than in men. Fewer studies are available regarding smoking and hypothyroidism (defined as Hashimoto thyroiditis, clinical hypothyroidism, subclinical hypothyroidism, or autoimmune thyroiditis), and the overall association with hypo thyroidism was weaker (odds ratio around 1. Several prospective studies provided data regarding the risk of developing multiple sclerosis in relation to smoking history in women (Table 12). Villard Mackintosh & Vessey (1993) also found an association with smok ing history and multiple sclerosis in the Oxford Family Planning Association cohort. In a small study using self-reported multiple sclerosis in a population-based study in Norway, the overall asso ciation with ever smokers (risk ratio 1. There is also some evidence of associations with pack years or smoking duration, but more variable effects have been seen with the amount smoked per day (Albano et al. Heavy drinkers without significant liver disease had significantly lower titres of IgA antibodies against acetaldehyde modified erythrocyte protein and IgG antibodies against oxidized or malondialdehyde-modified low-density lipoproteins, compared with patients with alcoholic liver disease (Viitala et al. A study in alcoholic patients in Japan reported an increase in the frequency of individuals homozygous for the C1 allele in men with alcoholic cirrhosis (Yamauchi et al. In contrast, there was no difference in either C1 or C2 allelic distribution in an earlier study conducted in Caucasian men (Carr et al. The i511 146 Chemical/Physical Agents and Autoimmunity allele 2 was found at a higher frequency in patients with cirrhosis than in heavy drinkers without liver disease. Jarvelainen and colleagues (2001) demonstrated that in Finnish males, expression of one T allele was associated with both alcoholic hepatitis and cirrho sis. The data on cytokine and metabolic enzyme gene polymorph isms in the human population as well as experimental studies with ethanol-fed rodents are indicative of the importance of inflamma tion, oxidative stress, and endotoxin in the pathogenesis of alcohol induced liver damage. Chronic ethanol exposure has been associ ated with the formation of alcohol-modified proteins, leading to autoantibody formation and immune-mediated damage to the liver. Obese strain chickens spon taneously develop a disease very similar to Hashimoto thyroiditis. Depletion of iodine after hatching, achieved by injections of potassium chlorite, reduced thyroid infiltration. In contrast, the onset of spontaneous thyroiditis was hastened by adding sodium iodide to the diet. The Biobreeding/Worcester rat has been widely used as a model for studying spontaneous diabetes mellitus, but it also develops autoimmune thyroiditis. The incidence of diabetes is very low, but many of the animals develop autoimmune thyroiditis. Clinical outcomes can be the result of immunoallergic, pseudoallergic, or autoimmune-like mechanisms. However, a comprehensive review of adverse autoimmune responses and autoimmune diseases associated with therapeutic agents is beyond the scope of this monograph, and only a few examples will be discussed below. Table 13 provides an abbreviated list of therapeutic drugs that have reportedly been associated with autoimmune reactions. When considering drug-induced autoimmunity, it is important to differentiate two situations. On the other hand, one given agent is associated with only one given type of autoimmune disease. The disease can also be systemic and consists of clinical manifestations and biological/immunological changes markedly different from those of spontaneous diseases. Interestingly, drug-induced systemic autoimmune-like reactions often resemble systemic hypersensitivity reactions, and this further illustrates overlapping mechanisms between immunoallergic and autoimmune-like reactions. The possibility of a lupus-inducing effect of the drug on T cell development in the thymus has been suggested (Quddus et al. Studies of the specificities of B cells that respond to chroma tin-reactive T cells at the initiation of this autoimmune process demonstrated a rapid and robust expansion of anti-chromatin-secret ing B cells, thus indicating the presence of a normal immune reper toire that includes non-tolerant autoreactive B cells that respond to strong T cell drive and are readily manifested if Fas-mediated activation-induced cell death is inhibited (Ayer et al. The adverse effects of D-penicillamine in animals are similar to those observed in humans. Studies using the popliteal lymph node assay demonstrated that D-penicillamine is capable of inducing an antigen. In rats, particularly Brown Norway rats, D-penicillamine induces a disease characterized by dermatitis, vasculitis, production of antinuclear antibodies, formation of circulating immune com plexes, and IgG deposits along the glomerular basement membrane (Donker et al. Interestingly, low 152 Chemical/Physical Agents and Autoimmunity dose pretreatment of D-penicillamine-treated Brown Norway rats was found to induce complete tolerance to a subsequent pathogenic dose of the drug (Donker et al. A number of experiments performed thereafter were supportive for the immune-based etiology of zimeldine-induced adverse effects (Kristofferson & Nilsson, 1989). Three individuals occupationally exposed to zimeldine developed allergy to the compound and showed positive patch and skin prick tests and positive response to zimeldine in the lymphocyte transformation test. The histology of these lesions can be characterized as either interstitial nephritis or glomerulonephritis, with specific diagnosis dependent on the presence of specific autoantibodies. Recent works using inbred animals have provided additional information on the pathogenesis of gold-induced renal autoimmunity. These findings indicate that gold compounds appear to cause polyclonal B cell activation to induce a variety of autoantibodies, but detailed mechanisms have not been established. Indeed, it has become clear that nearly all biopharmaceuticals induce anti bodies, although many are of human origin and thus immunolog ically tolerated (Schellekens, 2003). Treatments with recombinant therapeutic cytokines occasionally induce autoimmune phenomena. Aged mice appear especially sensitive to diethylstilbestrol treatment, as highly significant alterations were seen in the thymus and bone marrow of aged 21-month-old mice exposed subacutely to diethyl stilbestrol. Severe thymic hypocellularity develops in treated mice following five consecutive days of intraperitoneal injection with diethylstilbestrol. In contrast to the situation with females, diethylstilbestrol-treated males had higher levels of these antibodies than controls (Forsberg, 2000). The authors suggested that diethylstilbestrol modulates autoantibody production by B1 cells and may be an etiologic factor in the development of autoimmune diseases (Yurino et al. In a follow-up study, using two different groups of diethylstilbestrol-exposed women and an appro priate control group for each, no differences in the prevalence or serum titre of antibodies to five common viral diseases and six less common ones were observed. However, an increased prevalence was found in diethylstilbestrol-exposed women of a relatively rare immunological hyperreactivity, rheumatic fever, subsequent to microbial infection (strep throat) (Blair et al. In a further study (Blair, 1992), sera of diethylstilbestrol-exposed and non exposed women were examined for the presence of factors associ ated with autoimmune diseases. The study demonstrated that the incidence of high antibody titres to red blood cell antigen was higher in the diethyl stilbestrol-exposed females than in the controls.

Primary prevention of natural rubber latex allergy in the German health care system through education and intervention. It has been used in a variety of clinical situations (chemotherapy, cerebral edema) for its osmotic diuretic qualities. Complications: extravasation, which causes swelling and multiple cutaneous bullous eruptions in the hand and forearm. S Diagnostic methods Skin tests Intradermal skin test reported positive at 1/100 dilution. S Mechanisms Hyperosmolar solutes are capable of inducing non-cytotoxic basophil histamine release. Also, IgE mediated mannitol hypersensitivity has been identified by in vitro histamine release assay. Mannitol extravation during partial nephrectomy leading to forearm com partment syndrome. Anaphylaxis to excipient mannitol: evidence for an immunoglobulin E-mediated mecha nism. In vitro basophil histamine release induced by mannitol in a patient with mannitol-induced anaphylactoid reaction. S Diagnostic methods Skin tests: immediate skin tests may be positive (do not exceed a concentration of 1/100,000). Non-specific histamine release, meperidine being one of the strongest histamine releasers of all anaesthetic agents. Effects of general anesthetic agents in adults receiving electroconvulsive therapy: a systematic review. Acute allergic reaction associated with methohexital anesthesia: report of six cases. S Diagnostic methods Skin tests Prick test with 1/10 dilution Intradermal tests with dilutions 1/10,000 to 1/10 No midazolam specific IgE assay S Mechanisms Unknown. S Diagnostic methods the value of skin prick testing in opiate-sensitive individuals is uncertain as opiates cause non-spe cific wheals by direct degranulation of mast cells. Skin tests: With the concentration normally non-reactive in practice (10mg/ml) Prick test: 1/10 (1mg/ml). Dilution series is used starting with a 1/10,000 dilution and increasing the concentration up to the highest level that does not produce a reaction in non-allergic individuals. Patch tests may be used to confirm the diagnosis in acute generalized exanthematous reactions. One possible explanation is the unrestricted use of cough mixtures containing morphine derivates in such countries. S Mechanisms Non-specific histamine release by direct degranulation of mast cells; most reaction are not life threatening and are frequently misinterpreted as IgE-mediated allergy. Acute generalized exanthematous pustulosis caused by morphine, confirmed by posi tive patch test and lymphocyte transformation test. Contact allergy and respiratory/mucosal complaints from heroin (diacetylmorphine). Muscle relaxants account for 55 to 60% of all allergic reactions occurring during general anesthesia. No involvement of previous anaesthesias, atopy, food allergy and allergies to drugs not related to anaesthesia. In 80 to 90% of cases, the reaction begins with the induction of general anaesthesia, 5 to 10 minu tes after the drug has been injected. Non-allergic anaphylaxis: Chemically-mediated histamine release is far more likely to occur. It may be impossible to distin guish an IgE-mediated allergic event from a strictly chemically-mediated reaction. The symptoms in response to non-specific histamine release are generally less severe than when an IgE-mediated allergic reaction is involved. Systematic screening tests in the general population are not advisable due to the poor positive predictive value of the tests. Reducing the risk of anaphylaxis during anaesthesia: guidelines for clinical practice (Article in French). A new radioimmunoassay using a commercially available solid support for the detection of IgE against muscle relaxants. Evaluation of a new reactive radioimmunoassay of serum specific IgE against muscle relaxant drugs. It is a potent intravenous hypnotic agent which is widely used for the induction and maintenance of anesthesia and for sedation in intensive care units. In vitro histamine release test S Mechanisms An IgE-mediated reaction in most cases. One report suggested that this drug should be omitted in patients with allergy to egg or soy, due to lecithins which are present in the propofol vehicle. However, up to now, there is no convincing evidence to support allergy to egg or soy as a risk factor to propofol reactions. Lecithins contained in the propofol emulsion share quaternary ammonium ions which can react with anti-muscle relaxant IgE antibodies. Non-specific histamine release: propofol can induce concentration-dependant histamine release from human lung mast cells and at high doses can elicit bronchospasm. By prudence, avoid using propofol in patients with a history of egg or soy allergy. Diagnosis and pathogenesis of the anaphylactic and anaphylactoid reactions to anaesthetics. Mechanisms of activation of human mast cell and basophils by gene ral anesthetic drugs. S Diagnostic methods Skin tests: With the concentration normally non-reactive in practice (25mg/ml). Open test on previous fixed drug eruption lesions with lecture from 30 minutes to 24 hours. Specific IgE: Detection of thiopentone-reactive IgE antibodies by the ImmunoAssay method, which specificity is confirmed by hapten inhibition studies. However, technical difficulties including non-specific bin ding, the poor solubility of thiopental at physiologic pH and the low sensitivity of the test, make the use of ImmunoAssay in clinical practice inefficient. At high pH, binding of thiopental to the immunoabsorbent material can generate substituted ammonium ions that are normally internalized within the thiopentone molecule. Determinants involving the ring nitrogens in the pyrimidine nucleus can demonstrate cross-reactivity in vitro with sera from patients allergic to muscle relaxants. Non-specific histamine-releasing effects are observed with high concentrations of thiopental. The incidence of flushing on induction of anesthesia in patients who blush easily.

In cirrhosis, too much sodium can worsen ascites (belly swelling), edema (swelling in feet and legs), and esophageal varices (swol len veins in the food pipe). To maintain health, it is important for a patient with cirrhosis to Tip: restrict salt intake. All Patients with advanced liver prepackaged, processed, and of these contain the same amount disease should consume restaurant foods. In addition to not adding salt to food, it is important to cook and eat foods with low sodium contents. Herbs, spices, and marinades add to or enhance the avour of food without increasing sodium.

Patients with cirrhosis may experience day/night reversal this means a person is awake during the night and naps during the day. If this occurs, have 1 or 2 snacks between naps during the daytime and eat meals during the night. Nevertheless, it is important to stick as closely as possible to a regular eating schedule to help the liver.

Eigenvalues and the respective amount of variance explained by each factor are shown. A 12 B 12 C 12 10 10 10 8 8 8 6 6 6 4 4 4 2 2 2 0 0 0 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 Fig. A: total sample, B: Females (pink circles), Males (blue triangles), C: Age 30 (golden circles), Age>30 (brown triangles). Only 3 factors are obtained for Age 30 using the scree plot method (black arrow indicates elbow). Taking the scree plot solution into account and the extraction solution of the other groups, the fifth factor of Age 30 will be discarded and not used for further analyses. Many factors, however, do not contribute substan tially to the explanation of variance and are thus discarded (here: all factors with eigenvalues <1). The communalities represent the amount of variance in each variable explained by the retained factors. There are almost no differences in explained variance between Gender and Age groups (All groups: 88. If 1) a variable loads highly on the first factor and low on the second factor and 2) another variable loads highly on the second factor and low on the first factor, then these two variables are highly in dependent of each other (they correlate weakly). The load ings of all variables on the four extracted factors are shown for the total sample in Table 3. The interpretability of factors depends on factor loadings and sample size (Bortz, 1999, p. Due to the high number of individuals (n=11,771) there is no concern about in terpretability of factors. Furthermore, Factor Analysis allows to assess the contribution of every factor to the explanation of the total vari ance within a given set of variables. On free days, schedules seem to be not so strict as on work days, due to a lower loading value on work days (0. The highest loadings for each variable are shown in red, all additional loadings >0. Factors are sorted from left to right according to the amount of variance explained. Although slightly different in variance explained and in factor loadings, the basic structure of the factor solutions is highly con sistent. A more established and regu lar lifestyle and, in many cases, more stable employment could also reduce the impact of so cial influence on Age group > 30. However, these differences are also apparent between Females and Males (Roenneberg et al, 2004b; Fig. In spite of these differences, the general structure of factors seems to be highly consistent between Females and Males and stable throughout all ages. An association with mealtimes and other poten tial influences requires further investigation. Both are variables corrected for differences between sleep times on work days and on free days. A neglectable loading on F3 proofs corrections for sleep dept on work days to be sensible. The capability of a variable to predict (explain a cer tain amount of variance of) another variable reflects the strength of association between both variables;. Independent variabels can be either quantitative or dichotomous (binary), whereas the de pendent variable has to be quantitative. Some of the independent variables (factors) used here do not fulfill the assumptions and have to be transformed. A list of the German, Austrian, and Swiss cities with more than 100,000 residents is shown in Appendix 4. Furthermore, the amount of variance of the dependent variable(s) that can be explained by the independ ent variables is estimated. In Multiple Regression analysis, there are several ways to determine the association of pre dictors and the outcome. In the stepwise method, the predictor that shows the highest sim ple correlation with the outcome is chosen first and this predictor explains a certain variance of the outcome. Then, the predictor is chosen that shows the highest partial correlation (con trolled for the first predictor) with the outcome and this predictor explains a certain part of the remaining variance of the outcome, and so on. There is also the possibility to include predictors in a hierarchical (blockwise) manner. The order of predictors depends not on mathematical criteria but should be based on past research (Field, 2002). Because cases with missing val ues are removed from Multiple regression, the number of cases can differ between models. Here, the predictors were hierarchically included in the regression model, based on past re search. Within each block, predictors are included in a stepwise manner to assess the con tribution of each variable to the outcome of the model. Testing accuracy of regression model a) General assumptions Several crucial assumptions have to be checked before interpreting the outcome of the re gression model. Neither a tendency towards heteroscedasticity nor a deviation from normal dis tribution of residuals can be observed (for details see Fig. The variance of 0 N the standardized residuals should be -2 about the same for all levels of standard 500 ized predicted values. Still, after transformation, all distributions significantly deviate from normal distribution (K-S: p<0. When estimating a linear re gression line through Age 20 (brown, dotted line), it will be steeper than a regression line through all data points (golden, solid line). Fitting a linear regression results in a steeper regres 2 sion line when all age groups are considered (Fig. For all alternative models with various logarithmically transformed variables, sign and order of B, Beta, and t-values are identical. Because log10-transformation does not change the model substantially, no trans formation will be used for further models. Also, a reduced sleep consolidation with a wake time at an earlier phase of the body temperature and plasma mela tonin rhythm has been reported (Dijk et al, 2000). Light is the most powerful zeitgeber for entraining the circadian clock (Pittendrigh & Daan, 1976a; Aschoff & Wever, 1981; Pittendrigh, 1967; Kller, 2002; Panda et al, 2002; Czeisler, 1995; Czeisler et al, 1986; Jewitt et al, 1991; Jewitt et al, 1994; Minors et al, 1991) and the human circadian clock has been shown to be sensitive to very dim light conditions (Boivin et al, 1996; Kronauer et al, 1999) and different wavelengths (Thapan et al, 2001). Longer photoperiods could be hypothesized to advance sleep times due to a longer availability of sun light each day. Entrainment of circadian rhythms by non-photic zeitgebers has been discussed in several studies. Yoneyama et al (1999) showed that circadian rhythms in plasma melatonin and rectal temperature but not the sleep-wake-cycle change with photoperiod. However, this study used only nine individu als under extreme conditions (antarctica). Latitude has been shown to weakly correlate with urinary melatonin concentrations (Wetter berg et al, 1999). This study comprised data from latitudes between 31 degrees South to 77 degrees North. Our data, however, were collected only within a very narrow range of latitude (see 3. Variables in 2 2 dicated with a (*) were excluded during the analysis due to a lack of significance. Change of r indicates variance of the dependent variables explained by each predictor, also shown as 2 2 percentage of variance (% var. The months from April to September are linked to a shorter sleep duration on free days and a longer sleep duration on work days. Roenneberg et al (2003a) mentioned that daily sleeping patterns are influenced by three dif ferent clocks: i) the social clock, ii) the solar clock, iii) and the circadian clock. From many studies, light is known to be the strongest entraining signal for the circadian clock but results were obtained under laboratory conditions (Czeisler 1995; Czeisler et al, 1986; Jewitt et al, 1991; Jewitt et al, 1994; Minors et al, 1991). All variance not explained by (not clock related) biological and social factors should be ad dressed to properties of the circadian clock.
