Biofeedback for the treatment of anal incontinence in a child with ureterosigmoidostomy.

The case of a 7-year-old boy born with exstrophy of the bladder is presented. Biofeedback and behavioral therapy were employed in the treatment of anal incontinence, which occurred following ureterosigmoidostomy diversion. After 19 treatment and follow-up sessions over a period of 12 months, there was significant decrease in fecal/urinary incontinence. The patient was soiled 29% of waking hours over the first 4 weeks of treatment. This figure dropped to 9.7% over the last three sessions. Subjective satisfaction of parent, child, and teachers was high. These gains were maintained over a 12-month follow-up period. Given the design of the present study, it is not possible to determine whether the biofeedback per se had a specific treatment effect. The case demonstrates the usefulness of a broad-based behavior therapy in the management of fecal/urine soiling, which is a frequent, refractory complication of ureterosigmoidostomy.

Work hardening: occupational therapy in industrial rehabilitation.

Work hardening, presented in this paper as a "new" service for the industrially injured, is actually well grounded in the traditional models and practices of occupational therapy. From the profession's early roots in industrial therapy to the development of a variety of programs for the industrially injured through the 1950s and 1960s, the historical and philosophical bases of occupational therapy support the use of work as an evaluative and therapeutic medium. What is actually new is the adoption of terminology, technology, and a program format that fits in with the needs of consumers in the 1980s. Recent developments that created the need for the specialized services that occupational therapists are uniquely qualified to provide include growth of private sector vocational rehabilitation, changes in workers' compensation laws, and increasing costs of vocational rehabilitation. This paper describes work hardening in its present form. A case example is given that demonstrates how work hardening can be a cost-effective and time-saving bridge which spans the gap between curative medicine and the return to work.

Pseudophakia and intraocular pressure.

We studied the change in intraocular pressure in 373 consecutive eyes undergoing cataract extraction with intraocular lens implantation between Jan. 1, 1981, and May 31, 1982. There was a mean increase in intraocular pressure of 0.1 mm Hg following this surgery. This increase, however, was not statistically significant (P greater than .5). There was a mean rise in pressure of 0.8 mm Hg in the eyes undergoing intracapsular surgery and a mean fall in pressure of 0.6 mm Hg in the eyes undergoing extracapsular surgery (P less than .05). The change in pressure was unrelated to age, surgeon, or lens type. The results of a separate analysis of 16 eyes with a preoperative diagnosis of glaucoma and eight eyes with ocular hypertension were similar.

Plasma somatomedin activity and nutrition in the newborn infant.

Plasma somatomedin activity was measured by postnatal pig cartilage bioassay in 11 full term normal for dates, 10 preterm normal for dates and 5 full term small for dates newborn infants on the 2nd, 5th and 10th day after birth. On day 2 mean somatomedin activity was lower than in the adult in all three groups of infants. After that, a slight but not significant rise in somatomedin activity occurred in the full term but not in the preterm infants. No significant correlation was found between somatomedin activity and calorie, protein, lipid or carbohydrate intake.

Lymphocyte-dose response relationship in spontaneous lymphocyte mediated cytotoxicity (SLMC) measured by microcytotoxicity assay.

Titrations of spontaneous lymphocyte-mediated cytotoxicity (SLMC) in a 44-hour microcytotoxicity assay (MA) by serial dilutions of effector lymphocytes were performed to characterize the lymphocyte-dose response relationship, and to investigate the methodological basis for comparative cytotoxicity studies. The following lymphocyte fractions were used: unseparated, E rosetting, non-E rosetting, EA rosetting, and non-EA rosetting. Assays were performed against target cell lines from normal and malignant urothelium with high or low sensitivity to SLMC in allogeneic and autologous combinations, and against an osteosarcoma cell line. Analysis of SLMC titration curves showed that two different mathematical models could be used to describe the relationship between lymphocyte concentration and SLMC, I: linear relationship (log lymphocytes, CI) with exclusion of both high and low CI values, and II: sigmoid relationship (log lymphocytes, CI) which was transformed to linear relationship (log lymphocytes, log CI/100 - CI), including also high and low values. It is pointed out that perfect quantitative comparisons of SLMC in different combinations were complicated by statistically significant differences between the curve slopes. However, estimations based on experimental results in a range close to 50% cytotoxicity index (CI) may be acceptable, as the differences between slopes were small.

Cardiomegaly in hypoglycaemic small-for-gestational-age infants.

The chest X-rays of 15 hypoglycaemic small-for-gestational-age infants showed cardiomegaly in 10 infants, 4 had heart failure. None of the infants had respiratory distress syndrome, congenital heart disease, septicaemia, anaemia or polycythaemia; infants of diabetic mothers were excluded. Cardiomegaly disappeared with the normalization of blood glucose in most of the cases. The cause of the cardiomegaly and heart failure might be related to insufficient cardiac energy substrates in small-for-gestational-age infants. This condition should also be considered in the differential diagnosis of cardiomegaly and heart failure.

Metabolic responses to severe perinatal asphyxia in term newborn infants with particular reference to the changes in plasma free amino acids.

Blood glucose, blood lactate, plasma FFA, plasma alpha-amino nitrogen and 17 individual amino acids were determined on admission, and at 24 and 48 h after admission in severely asphyxiated term newborn infants. The blood glucose value was widely scatterred and the plasma FFA level was low on admission. The total free plasma amino acid content correlated closely with the severity of asphyxia-induced lactic acidosis. Among the 17 amino acids determined, 11 turned out to be significantly increased. The increase of plasma free amino acids might be toxic for the central nervous system, therefore parenteral feeding of asphyxiated neonates with amino acid mixtures can be dangerous.
