Subcutaneous fat necrosis (SFN) of the newborn characteristically affects full-term infants who have experienced perinatal distress, such as hypothermia, obstetric trauma, or asphyxia. We report a newborn who had pallor, deep breathing, and severe anemia immediately after birth. She developed SFN on the fourth postnatal day. Her condition improved after blood transfusions and the skin lesions resolved in 6 weeks. This appears to be the first report of SFN associated with anemia.

Ischemic cerebrovascular diseases are commonly induced by atherosclerosis and cardiogenic embolization but rarely they occur in association with Takayasu's arteritis and aortic lesion such as aortic dissection and aneurysm. Here we experienced two cases of acute aortic disease complicated by ischemic cerebrovascular disease (CVD). Patient 1 was a 77-year-old male. He complained of dyspnea and left hemiparesis. He was brought to our hospital by ambulance. Left hemiparesis and dyspnea improved soon. The patient only complained of left lower extremity pain and physical examination revealed hypotension. Brain CT showed no abnormality but chest CT revealed aortic dissection. The resection of the intimal tear and replacement of ascending aorta and aortic arch with 28 mm Hemashield graft were performed under hypothermia and selective cerebral perfusion. The postoperative course was uneventful and he has been doing well. Patient 2 was a 67-year-old female. She was found lying unconscious and brought to our hospital by ambulance. Physical examination revealed right hemiparesis and hypotension. Brain CT demonstrated low density area in the left corona radiata and ruptured aortic aneurysm was seen in abdominal CT. Just after the examination, the patient suddenly complained of severe back pain and died despite cardiopulmonary resuscitation. Aortic lesions can manifest ischemic symptom involving multiple organs following their vascular disorder. Aortic dissection rarely occurs in association with ischemic CVD and in that case it is likely to be seen by neurologists. Aortic dissection and aneurysm deteriorate so suddenly that immediate diagnosis and proper treatment are needed.

A case of Takayasu's arteritis resulting in extensive fusiform aneurysmal dilatation of the entire aorta extending from the aortic root to the abdominal bifurcation associated with aortic regurgitation is described. She underwent successful radical replacement of the aortic root, ascending, transverse arch and proximal part of the descending aorta employing simultaneous modified Bentall and Elephant trunk techniques. During aortic arch replacement the brain was protected by selective antegrade innominate perfusion under moderate hypothermia. A pattern to the best of our knowledge, has not been reported earlier.

A 68-year-old woman underwent surgical treatment for renal cell carcinoma associated with tumor thrombus extending into the right atrium. Although the tumor thrombus reached the level of the right atrium, there were no other apparent metastases. Combination therapy with interferon alfa plus tegafur/uracil (UFT) was attempted with the expectation of reducing the tumor thrombus, but there was no change. Successful management was achieved with right radical nephrectomy, right auriculotomy, and partial cavectomy using cardiopulmonary bypass under high-grade hypothermia. After removal of the tumor and thrombus, blood loss was 13,900 ml during the patient's recovery. She had mild heart failure for about two weeks after the operation, but recovered. She was discharged on the 40th day after the operation. Proper preparation for blood transfusion is the key point of this operation.

A 29-year-old gravid female presented at 22 weeks gestation with an acute Type I aortic dissection and coarctation of the aorta. She underwent emergent repair of her aortic dissection using cardiopulmonary bypass and hypothermia. At 25 weeks gestation, she underwent repair of her coarctation of the aorta. The patient had a cesarean delivery of a viable, normal male infant at 39 weeks gestation.

An extremely low birth weight (832 g) and 29 gestational week neonate underwent surgical ligation of patent ductus arterious 20 days after birth and repair of coarctation of the aorta two months after the first operation. She developed asphyxia neonatorum and was artificially ventilated because of IRDS and attack of apnea. At the first operation, anesthesia was maintained with fentanyl and sevoflurane. The only perioperative complication was severe hypothermia (34.5 degrees C). At the second operation, anesthesia maintenance was identical to the first operation. The only perioperative complication was mild hyperthermia (37.7 degrees C). The key points of anesthetic management were the use of a low inspired oxygen fraction to avoid retrolental fibroplasia at a gestational age before 32 weeks and management of the baby's temperature.

A 37-year-old female died of cerebral vasospasm as a complication of rewarming following hypothermia therapy for severe head injury. She presented with severe consciousness disturbance and anisocoria after falling down a flight of stairs. Computed tomography (CT) revealed a right acute subdural hematoma and temporal contusion. Following surgery, mild hypothermia was started and rewarming was completed by the 11th day. Neurological examination showed no abnormalities, but intracranial pressure (ICP) suddenly increased and she manifested anisocoria on the 13th day. Repeat CT revealed a low density area in the right middle cerebral artery region and cerebral angiography showed diffuse narrowing of the main arterial trunks. A cerebrospinal fluid (CSF) sample was collected using an intraventricular ICP monitoring catheter. The CSF level of 8-hydroxy-2'-deoxyguanosine was elevated during the rewarming period, indicating substantial deoxyribonucleic acid (DNA) oxidation. She died on the 15th day due to uncontrollable ICP. Histological examination at autopsy of the narrowed artery found the waving phenomenon in the internal elastic lamina and invasion of inflammatory cells into the adventitia. These findings constitute the possible evidence that free-radical-mediated oxidative DNA damage may be important in the genesis of severe vasospasm due to rewarming following hypothermia.

A 4-year-old girl was lost for 17 hours in a snowstorm. Upon discovery, her core temperature was 72 degrees F (22 degrees C). While undergoing endotracheal intubation in the emergency department, she experienced sudden ventricular fibrillation and cardiac arrest. Closed chest cardiopulmonary resuscitation (CPR) was instituted, and standard rewarming measures were begun. Despite this, neither core temperature, nor the patient's arrhythmia, changed. An infraumbilical "mini-laparotomy" incision was made, with placement of a large silicone peritoneal dialysis catheter into the abdomen. This was then connected to a rapid infuser device, with the delivery of 1L of warmed, normal saline every 90 seconds. The core temperature reached 29 degrees C in 15 minutes, and a palpable pulse was detected. Lavage was continued until core temperature reached 34 degrees C, at which time transport to the pediatric intensive care unit was arranged. She was extubated the next day and discharged home, on the fourth hospital day, with apparent complete neurologic recovery. This is the first report of the successful use of rapid high-volume peritoneal lavage for the treatment of accidental severe hypothermia in a pediatric patient.

A-37-year-old woman in shock condition was transferred to our hospital after cardiopulmonary resuscitation for ventricular fibrillation. She was unconscious and suspected of suffering ischemic brain damage, with pathologic reflexes and weak brain stem reflexes. Brain CT scan showed cerebral edema without hemorrhage or infarction and an electroencephalograph revealed slow alpha-theta waves. Chest CT scan and echocardiogram showed ascending aortic aneurysm with sever aortic regurgitation. An emergent operation was performed for progression of heart failure. There were no distortion or dilatation of the sinus of Valsalva and annuloaortic ectasia and aortic valve leaflets were almost normal. We considered that the aortic valve dysfunction was cause by dilatation of the sinotubular junction. Ascending aortic and aortic valve replacement were carried out to shorten cardiopulmonary bypass time and to prevent the progression of brain damage. Mild hypothermia was employed as a neuroprotective procedure for three days after surgery. The patient's neurological symptoms, which were right hemiparesis, facial apraxia and motor aphasia, improved and she was discharged from the hospital on foot without any neurological complications on the 47th postoperative day and returned to work after two months.

Profound hypothermia (core temperature of less than 28 degrees C) is a life threatening state and a medical emergency associated with a high mortality rate. The prognosis depends on underlying diseases, advanced or very early age, the duration prior to treatment, the degree of hemodynamic deterioration, and especially, the methods of treatment, including active external or internal rewarming. This is a case study of an 80-year-old female patient with severe accidental hypothermia (core temperature 27 degrees C). She was found in her home lying immobile on the cold floor after a fall. The patient was in a profound coma with cardiocirculatory collapse, and the medical staff treating her was inclined to pronounce her deceased. On her arrival at the hospital, she was resuscitated, put on a respirator and actively warmed. Very severe metabolic disorders were found, including a marked metabolic acidosis composed of diabetic ketoacidosis (she had suffered from insulin treated type 2 diabetes mellitus) and lactic acidosis with a very high anion gap (42) and a hyperosmotic state (blood glucose 1202 mg/dl). There were pathognomonic electrocardiographic abnormalities, J-wave of Osborn and prolonged repolarization. Slow atrial fibrillation with a ventricular response of 30 bpm followed by a nodal rhythm of 12 bpm and reversible cardiac arrest were recorded. The pulse and blood pressure were unobtainable. Despite the successful resuscitation and hemodynamic and cognitive improvement, rhabdomyolysis (CKP 6580 u/L), renal failure and hepatic damage developed. She was extubated and treated with intravenous fluids containing dopamine, bicarbonate, insulin and antibiotics. Her medical condition gradually improved, and she was discharged clear minded, functioning very well and independent. Renal and liver tests returned eventually to normal limits. Progressive bradycardia, hypotension and death due to ventricular fibrillation or asystole commonly occur during severe hypothermia. Respiratory and metabolic, sometimes lactic, acidosis, lethargy and coma, hypercoagulopathy, hyperosmolar state, acute pancreatitis and renal and hepatic failure are frequent complications of hypothermia. Underlying predisposing causes of hypothermia are diabetic ketoacidosis, cerebrovascular disease, mental retardation, hypothyroidism, pituitary and adrenal insufficiency, malnutrition, acute alcoholism, liver damage, hypoglycemia, sepsis, hypothalamic dysfunction, sepsis and polypharmacy, and especially, the use of sedative and narcotic drugs. Our case demonstrates once again that CPR once begun should continue until the successful rewarming because "no one is dead until warm and dead".
