Topical cardiac hypothermia has been shown to be a safe and effective means of providing protection for the ischemic myocardium during aortic cross-clamping. We report herein two cases of postoperative bilateral diaphragmatic paralysis which we believe resulted from hypothermic injury to the phrenic nerves. After open-heart surgery, both patients experienced prolonged weaning from assisted ventilation and severe orthopnea. Return of normal diaphragmatic and phrenic nerve function was demonstrated in one patient ten months after surgery. Failure to correctly interpret the respiratory failure and orthopnea led to confusion and erroneous types of therapy. Awareness of this complication should lead to improved care and postoperative management of patients.

A case of Wernicke's encephalopathy with ataxia, confusion, memory loss, partial seizures of complex behavior and hypothermia, subsequent to thiamine depletion due to chronic malnourishment and triggered by an episode of acute vomiting and diarrhea, is reported, Computerized tomography (CT-scan) depicted small bilateral lesions in areas adjacent to the walls of the third ventricle, common location of the lesions seen in autopsy material of Wernicke's encephalopathy. Early diagnosis and treatment with vitamin B complex supplemented with intensive mnemonic and cognitive therapy led to complete recovery in a ten day period.

A male alcoholic who presented with hypothermia and confusion was diagnosed as suffering from Wernicke's encephalopathy. He showed in addition signs of bulbar damage with cranial nerve signs, weakness of all limbs and absent oculo-vestibular responses. His course was complicated by recurrent episodes of aspiration pneumonia with death resulting from this cause. Neuropathological findings included typical features of Wernicke's encephalopathy as well as central pontine myelinolysis.

Normothermic blood cardioplegia was developed originally to be used during cardioplegic induction and reperfusion as an adjunct for enhancing metabolic reversal of biochemical alterations occurring before, during, and after total myocardial ischemia. This adjunct was introduced clinically after extensive experimental testing. By contrast, continuous normothermic blood cardioplegia without hypothermia was introduced clinically without a scientific infrastructure and has generated great interest because of its simplicity and encouraging early results, but has caused substantial confusion. This report is written to (1) clarify the role of normothermic blood cardioplegia as an adjunct to available hypothermic and antegrade and retrograde methods of myocardial protection, rather than as an alternative to them, (2) call attention to the misconception that continuous coronary perfusion avoids ischemia inasmuch as "unintentional ischemia" may occur despite continuous coronary perfusion, (3) identify theoretic and practical limitations of warm continuous retrograde blood cardioplegia exposed by testing after its clinical introduction, (4) enumerate the unanswered questions posed after clinical use of this method, and (5) focus on the self-imposed inflexibility created by adoption of adversarial positions in regard to cardioprotective strategies that impedes our ability to combine, rationally, the spectrum of approaches to myocardial protection that have evolved from the recognized limitations of individual methods.

An 18-year-old white woman had nausea, vomiting, weight loss, and a diagnosis of anorexia nervosa. Copper-colored skin was noted on physical examination, and serum chemistry values were normal. Subsequent fever, disorientation, and confusion led to the discovery of Addison's disease, which responded well to corticosteroid replacement therapy. Addisonian and anorexic patients exhibit clinical similarities, including nausea, vomiting, weight loss, abdominal pain, cold intolerance, hypothermia, and orthostasis. Other commonalities include prolongation of electrocardiographic PR and QT intervals and generalized slowing on electroencephalogram. Important differences include a brown color to the skin in Addison's disease instead of a yellowish color in anorexia. Addisonian patients also display hypocortisolism, hypoglycemia, and hyperkalemia, in contrast to the hypercortisolism, hyperglycemia, and hypokalemia seen in anorexia.

Systemic lupus erythematosus(SLE) is a prototypic autoimmune disease affecting various organ systems. Hypothermia is a rare manifestation of SLE. We experienced a case of SLE combined with hypothermia. A 36-year-old woman, who had been diagnosed as SLE 3 days before admission, admitted complaining of mental confusion. After admission, her body temperature, initially 36.1 degrees C, became 32.6 degrees C. Her core body temperature was less than 35.0 degrees C. Despite of warming with heating lamp and blankets, her core temperature did not reach 35.0 degrees C during 18 hours. Ten days later, her temperature exceeded 36.0 degrees C.

Accidental hypothermia due to environmental exposure is a common condition encountered in the wilderness setting. I report a case of hypothermia that occurred in New Hampshire to a 42-year-old, poorly prepared mountaineer. He presented with ataxia, impaired judgment, oliguria, and slight confusion, suggestive of mild to moderate hypothermia. He was treated in the field using passive and active external rewarming methods and 1 active internal method. The signs, symptoms, and progression of hypothermia are reviewed, and treatment options are discussed, with an emphasis on management of hypothermia in the wilderness setting. Additionally, more complicated treatment modalities are canvassed, as these are of use to rescue teams and expeditions. Current controversies regarding the treatment of hypothermia, resuscitation efforts, and potential complications are also mentioned.

Hypothermia has been employed as a method of neuroprotection for many decades. The evidence base for its use is limited, and the balance between benefit and risk is unclear. We felt that in light of this confusion it would be interesting to canvas the opinion of the members of The Neuroanaesthesia Society of Great Britain and Ireland. A questionnaire was sent to all 274 members enquiring into their use of hypothermia during a variety of different neurosurgical procedures and in the management of the head-injured patient. A 75% response rate was achieved. The results showed that over half (58%) of those who replied attempted to cool the patient during cerebral aneurysm surgery. Forty-one per cent of respondents attempt to induce hypothermia in the head-injured patient. However, for other neurosurgical procedures most felt that the disadvantages of cooling the patient outweigh the advantages. The use of hypothermia remains a contentious issue, and as yet there is no clear answer as to whether it should be employed as a method of neuroprotection.

Hypothermia, a reduction in the body's core temperature to <95.0 degrees F (<35.0 degrees C), is a preventable medical emergency usually caused by prolonged exposure to cold temperatures without adequate protective clothing. Warning signs and symptoms of hypothermia include lethargy, weakness and loss of coordination, confusion, uncontrollable shivering, and reduced respiratory or heart rate. Common risk factors are advanced age, substance abuse, altered mental status, and increased contact with substances that promote heat loss, such as water. This report describes three hypothermia-related deaths that occurred in the United States during 2003-2004, summarizes hypothermia-related mortality during 1979-2002, describes risk factors for and symptoms of hypothermia, and reviews measures to prevent hypothermia-related injury and death. Public health strategies tailored to persons at increased risk for exposure to excessive cold might help reduce hypothermia-related morbidity and mortality.

A 60-year-old woman presented to her primary care physician with fatigue and anemia. Laboratory evaluation revealed a hemoglobin level of 9.8 g/dL and an erythrocyte sedimentation rate (ESR) of 64 mm/hour. She subsequently developed nocturnal episodes of diaphoresis, confusion, and hypothermia. Capillary glucose measurements during the spells revealed hypoglycemia. During two supervised fasts, the patient's plasma glucose levels fell to 35 mg/dL and 32 mg/dL, respectively. Plasma insulin and C-peptide levels were appropriately suppressed, but a low concentration of beta-hydroxy-butyrate and normal increase of plasma glucose concentration after a glucagon injection suggested the presence of an insulin-like substance. Computed tomographic (CT) scan of the abdomen and subsequent positron emission tomographic (PET) scan revealed extensive lymphadenopathy. Biopsy of periaortic lymph nodes revealed Hodgkin's disease of the mixed cellularity type. Following chemotherapy, a complete remission ensued, the spells abated, and hypoglycemia was not induced by a 23-hour fast. We believe that the patient's Hodgkin's disease was producing an insulin-like substance. The observations of others suggest that this substance may be an autoantibody to the insulin receptor.
