The effects of multiple exposures to pesticides on plasma cholinesterase(ChE) activities and urinary p-nitrophenol excretion were evaluated in rats. Rats were received single dose i.p. with LD50/100(mg/kg) of organophosphorous(OP), organophosphorous-organochroline(OP-OC), organophosphorous-carbamate(OP-CAB), organophosphorous-organoarsenate(OP-OA) pesticides for 4 consecutive days. In repeated administration of pesticides, plasma ChE activities were decreased, but urinary p-nitrophenol were increased after the first injection and then decreased gradually. The recovery rates of ChE activities and p-nitrophenol excretion at 48 hours after the fourth infection were delayed in comparison with the baseline value of 24 hours before the first injection. Statistical significances were found between OP and other groups except OP-OA group after the second injection in plasma ChE activities, but in urinary p-nitrophenol excretion there was statistical significance only between OP and OP-CAB.

A prospective study of 99 pediatric patients were performed to investigate the incidence of perioperative airway complications presenting for various surgery with mild upper respiratory infections(URI's). Anesthesia administered via either face mask or endotracheal intubation. The severity of respiratory complications were scored. Endotracheal intubation in itself increased complication score compared to inhalation anesthesia with face mask. There were significant differences in the complication scores between control children and children fulfilling predetermined URI criteria. Complications showing significant differences were cough, airway obstruction, secretion. However, mean scores were too low to draw CONCLUSION that children with URI's should be postponed elective surgery.

High output heart failure due to congenital arteriovenous fistula is a rare disease and is difficult to treat. A 27 year old man, suffering from dyspnea, palpitation, lower extremity edema, and abdominal distension admitted May, 1987. At admission there were continuous thrill and bruit at left supraclavicular and infraclavicular area. The heart sound was irregular and rapid, and grade IV/VI pansystolic murmur was audible at the apex. Chest PA showed marked cardiomegaly with pleural effusion and notching at superior aspect of left 2nd rib. Selective left subclavian artery angiogram showed extensive congenital arteriovenous fistula at the area of left subclavian artery and its branches. After setrial feeding artery embolization and palliative operation, the fistula size decreased much with clinical improvement.

Neonatal and obstetrical problems related to the low birth weight infants were evaluated by a retrospective review of the medical records of the 186 low birth weight infants born at Yeungnam University Hospital during 3 years and 8 months from May 1, 1983 to February 28, 1987. The results were as follows: 1. The incidence of the low birth weight infants was 4.98% among 3,803 live births. 2. Male to female ratio was 1.02:1. 3. The incidence of the low birth weight infants was lowest in mothers of 25 to 29 years, increased in mothers of 19 years of less and 30 to 39 years significantly. 4. There was no difference in the incidence of low birth weight infants between primiparous and multiparous mothers. 5. Common obstetrical complications associated with low weight infants were multiple pregnancy, toxemia and premature rupture of membrane in order of frequency. 6. Common neonatal problems in low birth weight infants were jaundice, idiopathic respiratory, distress syndrome, asphyxia and metabolic derangement such as hypocalcemia and hypoglycemia in order of frequency.

Conventional dual chamber pacing (DDD) preserves atrioventricular synchrony but depend on appropriate sinus node function to achieve physiological heart rate with exercise by atrial tracking. Other indirect indicators of metabolic demand have been used to modulate pacing rate increases with exercise including sensing of pH, respiratory rate, ventricular repolarization and oxygen saturation. The activity sensing approach is unique in that noise generated by activity modulates the response and empirical programming of the unit allows for attaining the desired rate for a given level of activity. Physiologic rate increases can be obtained in patients with sinus node dysfunction or even atrial fibrillation. The lead can either be positoned in the atria for patients without atrial fibrillation or AV conduction disturbance or in the ventricle. We present two cases of rate responsive pacing using the Activitrax.
