Complete denture problem solving: a survey.

An investigation was carried out into the problems experienced by 114 referred patients with complete dentures who were considered to be difficult or to have difficult prosthodontic problems. The commonest problems were those of pain and lack of retention, due mainly to occlusal discrepancies and excessive VDO. Treatment was carried out on an individual basis with a large proportion of dentures being remade. However, a small number was satisfied by counselling alone without procedural treatment. A diagnostic denture technique was used for particularly difficult cases. This technique showed that, in two cases, technical prosthodontic inadequacies could definitively be excluded as the problem. The overall success rate for treatment was 80 per cent. Further studies on a larger patient sample are needed so that specific problems can be linked to cause and outcome in a meaningful manner.

Measured energy expenditure in pediatric intensive care patients.

Few data are available on energy requirements of mechanically ventilated, critically ill children. We measured the resting energy expenditure in 18 mechanically ventilated patients between ages 2 and 18 years, using indirect calorimetry. All patients had fractional inspired oxygen concentration less than 0.6, no spontaneous respirations, hemodynamic stability, and no fever or active infection, and were receiving 5% dextrose. All subjects were hypermetabolic, since the measured resting energy expenditure divided by the predicted basal energy expenditure from the Harris-Benedict equations was 1.48 +/- 0.09 (mean +/- SEM). The energy requirements calculated using "injury factors" and "activity factors" adapted for adults is 1.62 times basal energy expenditure. The injury factor for the pediatric multiple trauma patients should be 1.25 compared with 1.35 in adults. In these pediatric intensive care patients 33% +/- 8% of the energy is derived from carbohydrates, 53% +/- 8% from fat, and 14% +/- 2% from protein oxidation. In individual critically ill pediatric patients, energy requirements should be estimated by measuring their resting energy expenditure whenever possible and adding 5% for their activity. In the absence of the actual measurement of resting energy expenditure, the recommended energy requirement is 1.5 times basal energy expenditure. In this acute phase of injury, the daily nitrogen requirement is 250 mg per kilogram of body weight.

Hydrostatic pressure-induced colon trauma from a pool whip.

Hydrostatic pressure-induced colon injury is a rare occurrence in the pediatric population. We present a case of massive hydroperitoneum following a pool whip-induced injury. Although tension pneumoperitoneum or hydroperitoneum is rare, prompt recognition and surgical intervention are essential.

An angiographic catheter technique for selective endobronchial intubation.

Three children requiring selective endobronchial intubation were treated with a technique utilizing an angiographic catheter as a guide for the endotracheal tube. The procedure was successful in all three children and there were no long-term complications. Performed properly the technique is rapid, safe and avoids uncontrolled attempts at endobronchial intubation or the need for a flexible fiberoptic bronchoscope.

Postictal pulmonary edema in children.

Pulmonary edema complicating generalized tonic-clonic seizures has rarely been reported in children, although it has been well documented in adults. We report two patients, aged 8 and 9 years, who developed clinical and radiographic evidence of the condition. Fever, leukocytosis, and arterial hypoxemia are seen in the absence of cardiac dysfunction or infection. Rapid and complete recovery is to be expected if supportive therapy is instituted. Since these patients had no underlying cardiac pathology, control of the seizures will prevent further episodes.

Lack of evidence that formula-derived creatinine clearance approximates glomerular filtration rate in pediatric intensive care population.

During the four-year period from January 1980 to April 1984, 56 patients were admitted to the Pediatric Intensive Care Unit (PICU) whose care required timed urine collections using indwelling urinary catheters. The glomerular filtration rate derived from the clearance of endogenous creatinine with accurate timed urine volume is compared to that derived from the formula, 0.55 body length (cm)/plasma creatinine (mg/dl). There is a significant difference in the results between the two methods, p less than 0.0001. The largest divergence arises in those with creatinine clearance of less than 40 ml/min per 1.73 sq.m. In this subgroup, the formula derived glomerular filtration rates consistently overestimate the renal function and create a misleading assurance of minimal renal impairment. Therefore, our findings suggest that the latter formula is not applicable to PICU patients for consideration of fluid and electrolyte balance, administration of nephrotoxic drugs or criteria for dialysis.
