Diagnosis of congenital mitral and aortic stenosis from the fetal electrocardiogram.

A case of congenital mitral and aortic stenosis diagnosed from the fetal electrocardiogram (FECG) during labor is presented. Cardiologic work-up and autopsy findings in the neonate confirmed the diagnosis. This is the first case in which prenatal diagnosis of a specific anatomical lesion of the heart was made from the FECG and confirmed clinically as well as at autopsy.

Preliminary clinical outcome study of mild resuscitative hypothermia after out-of-hospital cardiopulmonary arrest.

The effects of mild hypothermia (MH) were investigated. From 1995 to 1996, 28 adult patients with out-of-hospital cardiopulmonary arrest (CPA) had return of spontaneous circulation and survived for more than two days. Thirteen patients were in the MH group. In the MH group, core temperature was maintained between 33 and 34 degrees C for 48 h, and then re-warmed to a temperature of 37 degrees C, at a rate of no greater than 1 degrees C per day. Fifteen patients, admitted before the MH protocol was instituted, were in the control group. Despite the fact that the number of witnessed arrests in the control group were greater than in the MH group, there were both more survivors (7/13 vs. 5/15) and more fully recovered patients (3/13 vs. 1/15) in the MH vs Control groups. Eleven of 13 MH patients, as compared to 6/15 controls developed pneumonia. Our study, although preliminary, suggests that MH might confer improved outcome, as has been shown in animal models, after CPA. This treatment is associated with an increase in pneumonic complications.

Problems of trace elements and vitamins during long-term total parenteral nutrition: a case report of idiopathic intestinal pseudo-obstruction.

An 8-year-old girl with chronic idiopathic intestinal pseudo-obstruction (CIIP), who is the first case of CIIP in Japan, has been receiving total parenteral nutrition (TPN) for more than 6 years. During this time, she experienced deficiencies of copper, zinc, vitamin A, vitamin B12, folic acid, and biotin, and an excess of vitamin A; she exhibited a series of signs and symptoms due to these deficiencies and vitamin A overdosage. Nevertheless, careful monitoring of serum levels of trace elements and vitamins and appropriate therapy have almost solved these problems. She has achieved normal physical and mental development and goes to school, while receiving home parenteral nutrition with an ambulatory infusion system.

Correction of tetralogy of Fallot accompanied by malignant hyperthermia. Case report.

A 5-year-old girl susceptible to malignant hyperthermia underwent total repair of tetralogy of Fallot. The initial operation was canceled because of abrupt hyperthermia and metabolic acidosis of unknown cause. Dantrolene was given orally as preoperative treatment and administered intermittently during surgery. Postoperative hyperthermic crisis was successfully treated with intravenous dantrolene combined with surface cooling, gastric tube irrigation with cold saline, and alcohol vaporization.

Successful surgical treatment of subaortic stenosis caused by an accessory mitral valve.

A 22-month-old boy with subaortic stenosis was found to have relatively mature mitral valve tissue beneath the aortic valve, associated with a hypertrophic and prominent interventricular septum. This tissue caused obstruction of the left ventricular outflow tract and resulted in a pressure gradient of 70 mmHg between the aorta and the left ventricle. Surgical treatment was successfully performed to excise the tissue and part of the hypertrophic ventricular septum. Results of microscopic examination of the resected specimen are shown and discussed.
