1/10. Efficacy of blood purification therapy for heat stroke presenting rapid progress of multiple organ dysfunction syndrome: a comparison of five cases.Five patients were admitted to our hospital because of classical heat stroke during the heat waves which attacked our country in the summers 1994 and 1995. The clinical and laboratory findings of all patients suggested the rapid progress of multiple organ dysfunction syndrome (MODS). blood purification (BP) therapy, in addition to conventional treatment, was performed in three of the patients. Despite their disastrous general condition, all completely recovered or recovered sufficiently to be transferred to a rehabilitation hospital. Two additional patients were treated with conventional treatment only and both died in 1-3 days after admission.Clinical characteristics and laboratory findings on admission showed no differences between the cases receiving BP therapy and those not receiving BP therapy. These findings suggest that, in heat stroke patients, additional BP therapy may provide a better prognosis than conventional therapy only. These beneficial effects of BP may have been due mainly to the removal of proinflammatory cytokines related to heat stroke.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
2/10. Disseminated zygomycosis due to rhizopus schipperae after heatstroke.A 21-year-old woman suffered heatstroke and developed diarrhea while trekking across south texas. The heatstroke was complicated by seizures, rhabdomyolysis, pneumonia, renal failure, and disseminated intravascular coagulation. The patient's stool and blood cultures grew campylobacter jejuni. The patient subsequently developed paranasal and gastrointestinal zygomycosis and required surgical debridement and a prolonged course of amphotericin b. The zygomycete cultured was rhizopus schipperae. This is only the second isolate of R. schipperae that has been described. R. schipperae is characterized by the production of clusters of up to 10 sporangiophores arising from simple but well-developed rhizoids. These asexual reproductive propagules are produced on Czapek Dox agar but are absent on routine mycology media, where only chlamydospores are observed. Despite multiorgan failure, bacteremia, and disseminated zygomycosis, the patient survived and had a good neurological outcome. Heatstroke has not been previously described as a risk factor for the development of disseminated zygomycosis.- - - - - - - - - - ranking = 0.2keywords = organ (Clic here for more details about this article) |
3/10. Antithrombin and near-fatal exertional heat stroke.Heat waves result in excess deaths, excess emergency department visits, and intensive care unit admissions for heat stroke. We describe the clinical features and 3-month outcome of a patient with near-fatal heat stroke, admitted to our intensive care unit in July, 2001. After heavily working for hours at a construction site during a heat wave, the 28-year-old male presented with 41.4 degrees C body temperature and multiorgan failure, consisting of neurological impairment, rhabdomyolysis, acute renal failure, disseminated intravascular coagulation, and acute respiratory distress syndrome (ARDS). In the first week there was no evidence of infection. Treatment included cooling, aggressive volume resuscitation, administration of antithrombin-III concentrates and steroids. The patient survived and recovered normal neurological, renal, respiratory and haematological function, and no disability persisted. This case illustrates survival and complete recovery after multiorgan failure in heat stroke with vigorous intensive care. Treatment with antithrombin and steroids and may well have contributed to the favourable outcome. Correction of reduced antithrombin iii levels to supranormal by therapeutic administration of antithrombin iii concentrate in disseminated intravascular coagulation of heat stroke was not associated with any bleeding complications.- - - - - - - - - - ranking = 0.4keywords = organ (Clic here for more details about this article) |
4/10. Fatal exertional heat stroke: a case series.BACKGROUND: Exertional heat stroke (EHS) is one of the most serious conditions that occur when excess heat, generated by muscular exercise, exceeds the body's heat-dissipation rate. The consequent elevated body core temperature causes damage to the body's tissues, resulting in a characteristic multiorgan syndrome, which is occasionally fatal. methods: We analyzed the fatal EHS cases that occurred in the Israeli Defence Forces during the last decade according to Minard's paradigm for evaluation of EHS predisposing factors, aiming to characterize the common features and unique circumstances leading to fatality. RESULTS: Accumulation of predisposing factors, particularly those concerning training regulations, coupled with inappropriate treatment at site, were found to be strong predictors of a grave prognosis. Analysis of the pathologic findings of the fatal EHS cases on autopsy revealed a possible association between the duration and length of exercise prior to EHS occurrence and the extent of pathologic findings. CONCLUSIONS: Strict adherence to existing training regulations may prevent further heat stroke fatalities.- - - - - - - - - - ranking = 0.2keywords = organ (Clic here for more details about this article) |
5/10. A case of severe heat stroke with abnormal cardiac findings.We document serial changes in the electrocardiogram (ECG) and myocardial markers in a case of severe heat stroke treated with cooling procedures. A 23-year-old comatose male with heat stroke was presented in the emergency room. The condition of the patient was complicated by hepatic failure, rhabdomyolysis, acute renal failure, and cardiac abnormalities. ECG revealed diffuse ST-T elevation; serum levels of myocardial markers were remarkably high and diffuse hypokinesis was observed on the echocardiogram. Cooling procedures, including applying cold vapor to the patient's skin, a gastric lavage with cold water, and an intravenous cold fluid infusion were not successful. Since multiple organ damage (heart, liver, central nervous system, and kidney) was evident, we utilized continuous hemodialysis and hemofiltration, using cold dialysate for efficient cooling. The patient recovered from the multiple organ damage and was removed from the intensive care unit 14 days after the onset. The cardiac abnormalities had normalized within several days without any damage to the myocardium. Q waves were not detected in any lead in the ECG. When interpreting ST-T elevation in the ECG of a heat stroke patient, caution should be used so as to not misdiagnose it as an acute myocardial infarction.- - - - - - - - - - ranking = 0.4keywords = organ (Clic here for more details about this article) |
6/10. heat stroke with multiple organ failure treated with cold hemodialysis and cold continuous hemodiafiltration: a case report.A 23-year-old comatose man was presented in the emergency room. He had been working inside a building under construction on a hot summer's day. His core body temperature was 42.1 degrees C and he was diagnosed with heat stroke. Urgent cooling procedures, including applying cold vapor to the patient's skin, a gastric lavage with cold water and an intravenous cold saline infusion, were not completely successful and his body temperature remained above 40 degrees C. Because his high temperature was refractory to conventional cooling procedures and we suspected that acute renal failure (ARF) by rhabdomyolysis would develop, we applied hemodialysis (HD) using cold dialysate (initially 30 degrees C and later 35 degrees C), followed by continuous hemodiafiltration (CHDF) with cold dialysate (35 degrees C) at a high flow rate of 18,000 mL per hour. The patient's body temperature fell below 38.0 degrees C within 3 h and was kept below 38.0 degrees C. Continuous hemodiafiltration was continued for one week. During the first week, the patient suffered from multiple organ failure (MOF) involving renal failure, as well as the failure of heart, liver, lung, and central nervous systems. disseminated intravascular coagulation also developed. However, by virtue of cold CHDF, he almost recovered 3 weeks after the onset, except for remaining mild liver and renal dysfunction. In severe heat stroke, cold HD and high flow, cold CHDF should be a therapeutic choice for cooling and treatment of MOF. Considering mild liver and renal dysfunction still remained, this case suggested these procedures should be initiated at the very beginning of the treatment of severe heat stroke.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
7/10. Case report: severe heat stroke with multiple organ dysfunction - a novel intravascular treatment approach.INTRODUCTION: We report the case of a patient who developed a severe post-exertional heat stroke with consecutive multiple organ dysfunction resistant to conventional antipyretic treatment, necessitating the use of a novel endovascular device to combat hyperthermia and maintain normothermia. methods: A 38-year-old male suffering from severe heat stroke with predominant signs and symptoms of encephalopathy requiring acute admission to an intensive care unit, was admitted to a ten-bed neurological intensive care unit of a tertiary care hospital. The patient developed consecutive multiple organ dysfunction with rhabdomyolysis, and hepatic and respiratory failure. Temperature elevation was resistant to conventional treatment measures. Aggressive intensive care treatment included forced diuresis and endovascular cooling to combat hyperthermia and maintain normothermia. RESULTS: Analyses of serum revealed elevation of proinflammatory cytokines (TNF alpha, IL-6), cytokines (IL-2R), anti-inflammatory cytokines (IL-4) and chemokines (IL-8) as well as signs of rhabdomyolysis and hepatic failure. Aggressive intensive care treatment as forced diuresis and endovascular cooling (CoolGard and CoolLine) to combat hyperthermia and maintain normothermia were used successfully to treat this severe heat stroke. CONCLUSION: In this case of severe heat stroke, presenting with multiple organ dysfunction and elevation of cytokines and chemokines, which was resistant to conventional cooling therapies, endovascular cooling may have contributed significantly to the reduction of body temperature and, possibly, avoided a fatal result.- - - - - - - - - - ranking = 1.4keywords = organ (Clic here for more details about this article) |
8/10. Heatstroke in the super-sized athlete.We present a 16-year-old male athlete with hyperthermia, altered mental status, and respiratory distress during summer football practice. Multisystem organ failure ensued, which he survived. malignant hyperthermia was suspected in this patient who had a history of rhabdomyolysis. Specific muscle contracture testing later eliminated this diagnosis. This case discusses the importance of rapid hydration with isonatremic fluid, aggressive cooling, and full support measures, including plasmapheresis, further diagnostic efforts to evaluate potential causes of rhabdomyolysis, and planning for physical and emotional rehabilitation.- - - - - - - - - - ranking = 0.2keywords = organ (Clic here for more details about this article) |
9/10. heat stroke and multi-organ failure with liver involvement in an asylum-seeking refugee.heat stroke is the result of exposure to high environmental temperature and strenuous exercise representing a medical emergency characterized by an elevated core body temperature and central nervous system disorders. Slightly elevated liver enzymes, lacking clinical significance, seem to be frequent in heat stroke, whereas severe, clinically relevant, hepatocellular injury has been observed in only a minority of cases. In the present report we describe the case of an otherwise healthy young asylum-seeking refugee from east timor, who developed severe heat stroke during his transportation to greece in a closed container on a ship under unusually high temperatures. He was admitted to the hospital with severe multi-organ failure. After a short period of initial improvement, he developed severe hepatocellular injury and hepatic encephalopathy. Other causes of liver damage were excluded. The patient completely recovered.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
10/10. A case of multiple organ failure due to heat stoke following a warm bath.heat stroke is a potentially fatal disorder that's caused by an extreme elevation in body temperature. We report here an unusual case of multiple organ failure that was caused by classical, nonexertional heat stroke due to taking a warm bath at home. A 68 year old diabetic man was hospitalized for loss of consciousness. He was presumed to have been in a warm bath for 3 hrs and his body temperature was 41degrees C. Despite cooling and supportive care, he developed acute renal failure, disseminated intravascular coagulation (DIC) and fulminant liver failure. Continuous venovenous hemofiltration was started on day 3 because of the progressive oligouria and severe metabolic acidosis. On day 15, septic ascites was developed and acinetobacter baumanii and enterococcus faecium were isolated on the blood cultures. In spite of the best supportive care, the hepatic failure and DIC combined with septic peritonitis progressed; the patient succumbed on day 25.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
