Accidental hypothermia is not a frequent cause of death in Australia. Moreover it is rare to have an admission to hospital with a core temperature below 32 degrees C. Among the cases described in the literature, it is clear that temperature and prognosis are related. Our patient presented with severe accidental hypothermia and even though the admission core temperature was below 26 degrees she was successfully discharged from hospital after active re-warming with three different devices. She had laboratory and ECG findings associated with severe hypothermia.

A 68-year-old woman with anti-phospholipid antigen syndrome (APS) was proposed to undergo partial pulmonary resection for lung cancer. She suffered from mild cerebellar ataxia. Exercised 201Tl myocardial scintigraphy was performed due to abnormal Q wave in preoperative electrocardiography and showed old myocardial infarction in inferior-to-posterior area without myocardial ischemia. Cardiac function was marginally decreased in cardiac echographic evaluation. Arterial thrombosis by APS might cause cerebellar ataxia and myocardial infarction. Low molecular weight heparin (LMWH) was continuously infused from 1 hour prior to arrival in an operation room. Elastic stockings (ES) were worn from the morning of the operation in combination with the use of intermittent pneumatic compression apparatus (IPC). Significant bleeding was not observed perioperatively. Hypothermia was avoided by forced-air-warming therapy. She was transferred to ICU after the end of the operation. She was returned to her ward without IPC on the first postoperative day. Warfarin was given with the beginning of ambulation on the second postoperative day to keep PT-INR about 2. On the third postoperative day LMWH was discontinued and ES were taken off. The postoperative course was uneventful.

We report a case of a 69-year-old white female who presented with a large left internal carotid artery occlusive stroke from a cardiogenic embolus. She was enrolled in an institutional study using a specially designed cooling helmet. Bilateral intracranial pressure (ICP) and temperature probes were placed to determine if there was any differential cooling and ICP compartmentalization between the two hemispheres. We demonstrated a significant temperature gradient between the infarcted and the non-infarcted hemisphere. A significant inter-hemispheric ICP gradient was also observed. We believe that this is the first demonstration of preferential cooling of the infarcted hemisphere over the non-infarcted hemisphere with regional surface hypothermia.

In winter, French Medicalised Ambulance Service rescued a 50-year-old patient after suicide attempts by jump from a bridge in the Seine. The body was discovered after more than 10 minutes of immersion. She was unconscious and in deep hypothermia with circulatory arrest. Basic CPR was started immediately and oral intubation and 100% oxygen ventilation was performed. Ventricular fibrillation appeared but repeated defibrillation failed due to profound hypothermia (rectal temperature: 28 degrees C). The patient was immediately transported to hospital. CPR and mechanical ventilation was continued during transport. The patient was taken in emergency room. The oesophageal temperature was 22 degrees C. Rewarming using extracorporeal circulation was immediately initiated after insertion of femoral access. At 27 degrees C, ventricular fibrillation started and was converted by external defibrillation to a pulse-generating cardiac rhythm. At 360 minutes, the patient's rectal temperature had reached 36 degrees C and she was disconnected from cardiopulmonary bypass with inotropic support. She was transferred to the intensive care unit after 9 hours of resuscitation, rewarming and stabilisation. Mechanical ventilation was needed for 15 days because of adult respiratory distress syndrome. Renal failure, pneumonia also occurred. She was successfully extubated on day 15 and was discharged from intensive care unit on day 21, suffering no neurological side effects.

Pulmonary thromboendarterectomy was performed on a patient with chronic pulmonary thromboembolism showing thrombophilia. The patient was a 56-year-old female with the above condition complicated by congenital protein C deficiency. She was admitted to our hospital with severe dyspnea accompanied by right ventricular failure. A pulmonary arteriogram showed occlusion and stenosis from lobar to segmental arteries. Cardiac catheterization showed marked pulmonary hypertension. A lung perfusion scintigram revealed multiple defects in the right and left lungs. After the insertion of an inferior vena cava filter, she was operated on. Following a median sternotomy, thromboendarterectomy of the bilateral pulmonary arteries was performed using deep hypothermia and intermittent circulatory arrest. Circulatory arrest was employed in three periods totaling up to 36 minutes. After surgery, she had improvements in pulmonary hypertension and pulmonary vascular resistance. She maintained improved lung functions, and remained in the New York Heart Association functional class I for more than two years and eight months after surgery.

A 65-year-old woman received a bovine pericardial patch repair with a sutureless technique for a left ventricular free-wall rupture. Three months later the Dor operation was performed for a left ventricular aneurysm. She was admitted again with a mycotic aneurysm 15 months after the Dor operation. Computed tomography suggested a rupture of the pseudoaneurysm due to a damaged endoventricular patch. An emergency Dor reoperation was performed with profound hypothermia. Right thoracotomy was performed with insertion of a left vent catheter via the right upper pulmonary vein in order to prevent ventricular distention. Omentopexy was performed to avoid infection of the mediastinum. The patient had an uneventful postoperative course.

Differential diagnosis of neonatal respiratory distress includes pulmonary and systemic disorders and anatomic problems compromising respiratory system. We report on a 2770-g female born to a 29-year-old gravida 3, para 2 woman after 34 weeks of gestation. Antenatal ultrasound performed in week 8 and 21 was normal. The infant was delivered by cesarean section after amniotic membranes had been ruptured for less than 12 hours due to signs of fetal distress. The Apgar score was 3 and 3 at 1 and 5 minutes, respectively. The infant was intubated and resuscitated, and transferred immediately to the neonatal intensive care unit. She had an extremely protuberant and cyanotic abdomen. Dilated cutaneous collateral vessels were apparent in the periumbilical region. Abdominal sonography showed cystic multiloculated tumorous mass filled with dense, flocculent content at the level of hepatic portal. The tumorous mass occupied the majority of the abdomen with caudal extension toward the pelvis and dorsally toward the spine. The liver was displaced high under the diaphragm with the left liver lobe in the left hemiabdomen. On x-ray the lung were collapsed due to a large abdominal mass in the right hemiabdomen that displaced the right diaphragm and intestines contralaterally. She soon developed bilateral pneumothoraces. Drainage and continuous suction were started. The infant failed to improve despite all attempts and died. On autopsy, an extremely large, mobile, multichambered, solitary cyst was found. It was attached to the mesenteric side of the ileum by its own thin peduncular stalk and had no communication with the remainder of the gut. It occupied the majority of the abdomen. Histologic section revealed a well-developed smooth muscle wall and inner mucosa of small bowel type. Respiratory distress is a common problem in premature infants. The majority of cases are due to pulmonary disorders (e. g., hyaline membrane disease, meconium aspiration syndrome, pneumonia), hypothermia, metabolic acidosis, anemia, and congenital heart disease. Anatomic problems including space occupying lesions are less common. Duplications of the alimentary tract in infants and children are rare congenital anomalies. Although symptoms can occur at any age, they usually present during the first year. In our patient, intraabdominal mass caused severe respiratory distress and respiratory failure in the first hours of postnatal life. This had been seen before only as a complication of intrathoracic lesions extending into the abdominal cavity. Pathology revealed spherical intestinal duplication that was completely separated from the alimentary tract. Embryologically, it was a localized duplication. Respiratory distress in our patient was refractory to all means of mechanical ventilation. Poor lung compliance was the consequence of prenatal lung hypoplasia and inadequate postnatal lung expansion due to the duplication cyst space occupying character and its compressive effect. Prenatal diagnosis was the child's only chance for survival but it was not made. Duplications of the alimentary tract can present a diagnostic challenge even in the first hours of life. They should be included in the differential diagnosis of severe respiratory distress, especially in premature infants in which timely prenatal diagnosis cannot be always made. We propose their inclusion among other space occupying lesions that might be the cause of severe respiratory distress even in the earliest neonatal period.

A 1-year-old girl with influenza-associated encephalopathy initially exhibited prolonged febrile convulsions and subsequent drowsiness. She became unconsciousness and experienced a cluster of seizures 4 days later. Diffusion-weighted magnetic resonance imaging (DWI) showed high signal intensity in the bilateral frontal white matter. This signal change migrated to the bifrontal cortical areas and the caudate nuclei within 10 days, when T2 elongation appeared over the gray and white matter of frontal lobes. Choreoathetosis and oculogyric crisis were transiently noted at this period. Frontal lobe signs, including the forded mouth opening response, after diminution of these movement disorders. The DWI signal change subsequently resolved and frontal cortical atrophy appeared thereafter. Levels of inflammatory cytokines in the cerebrospinal fluid were normal during the acute phase of clinical course. The biphasic clinical course with initial prolonged seizure, involvement of the frontal lobes, and the progression of signal change on DWI from white to gray matter, meets the characteristics of "status epilepticus-type acute encephalopathy" suggested by Shiomi et al. Although pentobarbital infusion, steroid pulse therapy and mild hypothermia did not show any apparent effects on the clinical course of this patient, further trial of these therapies may be warranted for the treatment of this type of encephalopathy.

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.

We report an 18-year-old female patient with cardiac arrest due to pulseless electrical activity caused by a massive pulmonary embolism. Cardiopulmonary resuscitation was continued for more than one hour. Although the initial clinical signs and symptoms suggested poor outcome, immediate intravenous thrombolysis was instituted. After return of spontaneous circulation (75 minutes) the patient was still comatose and mild therapeutic hypothermia (32.5 degrees C) was instituted for brain protection during the first 24 hours. She recovered uneventfully without neurological deficit. Therapeutic hypothermia may be effective for neuroprotection in non-VFcardiac arrest.
