Intermittent hyperthyreosis occurs under various forms of stress, especially heat stress. The clinician may diagnose such cases as masked or apathetic hyperthyroidism or "forme fruste" hyperthyreosis or thyroid autonomy. As most routine and standard tests may here yield inconsistent results, it is the patients' anamnesis which may provide the clue. Our Bioclimatology Unit has now seen over 100 cases in which thyroid hypersensitivity towards heat was the most prominent syndrome: 10-15% of weather-sensitive patients are affected. The patients complain before or during heat spells of such contradictory symptoms as insomnia, irritability, tension, tachycardia, palpitations, precordial pain, dyspnoe, flushes with sweating or chills, tremor, abdominal pain or diarrhea, polyuria or pollakisuria, weight loss in spite of ravenous appetite, fatigue, exhaustion, depression, adynamia, lack of concentration and confusion. Determination of urinary neurohormones allows a differential diagnosis, intermittent hyperthyreosis being characterized by three cardinal symptoms: 1. tachycardia -- every case with more than 80 pulse beats being suspect (not specific); 2. urinary histamine -- every case excreting more than 90 mug/day being suspect. Again the drawback of this test is its lack of specificity, as histamine may also be increased in cases of allergy and spondylitis; 3. urinary thyroxine -- every case excreting more than 20 mug/day T-4 being suspect. This is the only specific test. Therapy should make use of lithium carbonate and beta-blockers. Propyl thiouracil is rarely required.

A syndrome of headache, chills, sweating, nausea, and exhaustion during and after haemodialysis is described and likened to metal fume fever. A patient has been cured of this syndrome following removal of copper-containing parts from the water-path of her home dialysis system.

A new edible mushroom, known as oyster mushroom (Pleutrotus Florida, variety of Pleurotus ostreatus) has recently gained commercial importance in Europe, having been imported from the U.S.A. in 1963 and cultivated in Germany between 1972 and 1973. Several persons concerned with the cultivation and industrial production of this mushroom fell ill, after close contact with it over a period of some months, with exhaustion, headache, chills and fever, and cough. These symptoms, similar to those of "farmer's lung" were proved to be caused by the spores of Pleurotus Florida, inhaled in harvesting rooms. The suspicion of an allergic disease, is supported by the history and clinical picture, and the demonstration of precipitating antibodies against spore extracts (Ouchterlony test). The antigens probably have a high molecular weight and are fixed to the spore membrane. Experimental sensitisation of rabbits also revealed precipitins. One of three isolated antigens produced antibodies identical in man and rabbit.

This review focuses on the physiological, behavioural and environmental factors which predispose to frostbite. Also prevention of frostbite is summarised. Predisposing factors may increase heat loss, decrease heat production, decrease the insulation of the clothing, make people especially susceptible to cold or make them to behave inadequately. Marked increase in convective or conductive heat loss is often the immediate reason for frostbite. Wind (as described by wind chill index) increases convective heat loss and touching of metal objects increases conductive cooling. Poor insulation of the clothing is also a common reason of frostbite. The insulation can be insufficient when clothing is wet, tight, permeable to wind or does not cover the cold sensitive body parts. Individual factors predisposing to frostbite are inadequate behaviour, low physical fitness, fatigue, dehydration, earlier cold injuries, sickness or poor circulation in peripheral parts of the body. Frostbite is often associated with the use of alcohol. To prevent frostbite, it is necessary to recognise cold risks, practise tasks in the cold, eat and drink well, have physical exercise, have sufficient clothing (also spare clothing), change into dry clothing if necessary and take care of companions. In the cold it is not advisable to get fatigued until exhaustion, sweat excessively, use tight and/or wet clothing, drink alcohol, smoke and expose oneself unnecessarily to wind, metals or fluids.

PURPOSE: To determine the effect of chronic fatigue syndrome (CFS) illness duration and onset type on the likelihood of reporting a symptom during successive follow-up periods.METHODS: In 1997, a two-phase RDD survey in Wichita, Kansas, was conducted to estimate the prevalence of CFS. Phase I identified 56,154 respondents 18-69 years of age and screened for severe fatigue, extreme tiredness or exhaustion lasting for 1 month or longer. In phase II an equal number of fatigued (n = 7,176) and randomly selected non-fatigued subjects were asked about 8 CFS and 13 non-CFS symptoms, as well as the presence of specific medical and psychiatric conditions. Eligible respondents were clinically evaluated to establish CFS diagnosis. Phase II respondents were re-contacted at 12- (n = 4,331) and 24-months (n = 4,266) for additional follow-up and diagnosis. In this study we considered symptoms reported as being present most of the time during each successive observation period. Generalized estimating equations were used to model symptoms over time and to address study questions. Such a model accounts for correlations among repeated symptoms for each subject. We used an auto-regressive structure for the correlation matrix, assuming the correlations between each pair of repeated symptoms should decrease as the time between symptoms increased.RESULTS: There were 74 CFS patients who had been ill for 1 to 20 years (median = 6.3 years). Among these, 46 reported gradual and 28 reported sudden onset. Symptoms fluctuated over the course of illness. However, only stomach pain (non-CFS symptom) was more likely to be reported as duration of illness increased (p < 0.05). There was no association between onset type and the likelihood of reporting a symptom during an interview, except that chills and severe headaches were more likely to be reported by sudden cases.CONCLUSIONS: The likelihood of expressing CFS and non-CFS symptom "most of the time" is the same across years of illness. More analyses are warranted to consider expression of symptoms for >/=6 months and severe symptoms.

Malaria is a protozoan disease caused in humans by the genus Plasmodium of which four species are known: P. falciparum, P. vivax, P. ovale, and P. malariae. It is transmitted through the bite of infected female mosquitoes of the genus Anopheles. Malaria is endemic in tropical and subtropical regions of the world. It is characterized by extreme exhaustion associated with paroxysms of high fever, sweating, shaking chills, and anemia. Approximately 40% of the world''s population, mostly those living in the poorest nations, are at risk. Much of the deaths due to malaria occur in Africa, mostly among children. The search for prevention and control interventions that are effective and sustainable remains an abiding challenge for national governments and international health agencies. To this end, the World Health Organization and several nongovernmental organizations are investing in the use of insecticide-treated mosquito nets (ITMNs) as a viable option. Trials of ITMNs in the 1980s and 1990s showed that they reduce deaths in young children by an average of 20% and multilateral agencies, spearheaded by Roll Back Malaria (RBM), seek to have 60% of the populations at risk sleeping under ITMNs by 2005. All pesticides are toxic by nature and present risks of adverse effects that depend on toxicity of the chemical and the degree of exposure. While there is agreement that ITMNs can be effective in reducing malaria morbidity and mortality under field trials, a number of factors relating to their sustainability and contribution to health improvement in less-developed countries have yet to be determined. In particular, the adverse effects associated with their long-term use and misuse has yet to be fully evaluated. Although this paper examines potential neurotoxic and neurobehavioral effects of long-term use of ITMNs and discusses priority public health actions for protecting the health of users, it forms the basis for further research.
