Congenital abnormalities of the lymphatic system: a new clinical classification.

The numerous clinical presentations of congenital abnormalities of the lymphatic system in children and the confusing terminology used to describe their pathologic diagnoses impede the physician's understanding of the condition. The clinical classification based on the actual symptoms of the congenital problems we have presented here should help the physician identify the specific abnormality and a potential treatment. Future research should concentrate on the specific causes and the treatment of these congenital abnormalities.

Oxybutynin efficacy in the treatment of primary enuresis.

The effectiveness of oxybutynin in the treatment of primary enuresis was evaluated in a double-blind study. A total of 30 children (25 boys, five girls), at least 6 years of age, with primary enuresis and no daytime incontinence or history of other urinary tract problems were selected at random from an enuresis clinic population. The study was explained to the families and they were told how to keep records of nocturnal bed-wetting episodes and side effects. The patients were treated with a 10 mg of oxybutynin at suppertime for 28 days. Before or after the treatment period, all children received an identical placebo for 4 weeks. Two-sided paired t tests were used to compare frequency of nocturnal enuresis. Frequency during the drug regimen did not differ significantly from that during the placebo study. There were no differences in findings between boys and girls or between children who had previously taken imipramine and those who had not. The study showed no evidence that oxybutynin is effective in treating primary enuresis.

Effects of different methods of treatment of primary enuresis on psychologic functioning in children.

Sixty-two children with primary nocturnal enuresis were assigned randomly to one of two groups. Group 1 was treated with imipramine hydrochloride, and group 2 received a course of treatment with the Mozes Detector. Seventeen children from group 1 and 18 from group 2 were tested with the age-appropriate form of the Cattell personality questionnaire on three occasions: at the time of entry into the study, 2 months later and at follow-up, an average of 16 months later. The patients in group 2, who were older, had a higher rate of cure than did the patients in group 1. They also had significantly higher levels of extroversion and significantly lower levels of neuroticism at follow-up than did those in group 1. These findings indicate that better results are seen with the Mozes Detector than with imipramine in older children with primary nocturnal enuresis.

Multidisciplinary survey of erectile impotence.

A study was done of 220 men referred principally by family physicians to a multidisciplinary erectile dysfunction study group to determine the factors causing or contributing to impotence that had persisted for more than 2 months and for which no cause was apparent. The men were aged 21 to 79 (mean 50.3) years, and the duration of impotence was a few months to 15 years (mean 2.65 years). The men were to be assessed from general medical, endocrinologic/metabolic, psychiatric and urogenital viewpoints. The significance of the causal or contributory factors detected was scored by application of defined criteria and a four-point scale. The degree of loss of potency and of libido as well as level of concern were also scored by each specialist. Impotence was complete in 60%, and an associated decline in libido was reported by 38%. The level of concern was high--that is, normal--in 81% and slightly reduced in 9%. Full investigation by all the specialists was precluded by the severity of other conditions in 16 patients, by the return of potency following relief of anxiety/depression or genitourinary tract infection in 16 and for logistic or other reasons in 34. Although the cause of the impotence could be attributed in 186 of the patients, only 154 were fully assessed. Among these patients general medical factors were contributory in 46%, endocrinologic/metabolic factors in 44%, psychogenic factors (primary or secondary) in 60% and urogenital factors in 49%. Multiple contributing factors were identified in 65%, which underscores the importance of a multidisciplinary approach to assessing many cases of impotence.

Erectile impotence: a clinical challenge.

The wide range of factors that may contribute to impotence is reviewed in an attempt to establish a systematized approach for assessing etiologic factors. The effects on potency of ageing, general fitness, weight, debilitating disease, use of therapeutic and other drugsincluding alcohol and neurogenic, vasculogenic, endocrine/metabolic, urogenital and psychogenic factors are considered and discussed. The review also affords a rationale for the methodology employed.

Calcific bridging of dental pulp caused by iatrogenic hypercalcemia. Report of a case.

A case of renal osteodystrophy treated with high doses of vitamin D is presented. The treatment, carried out when the patient was between 3 1/4 and 6 years of age, induced hypercalcemia (up to 13.9 mg./dl.) which resulted in dentinal bridging corresponding chronologically to the part of the root developing at this age. Dentinal bridging associated with iatrogenic hypercalcemia has not been reported previously.

Salmonella epididymitis with recurrent septicemia in diabetic patient.

A diabetic male patient presented with recurrent septicemia due to Salmonella panama. The nidus from which reinfections of the blood stream occurred was apparently localized in the epididymis. Cultures of semen grew Sal. panama while cultures of urine and stool showed no pathogens. This is the fifth reported case of salmonellosis involving epididymis and/or testicle, the first in a diabetic, and the first in which salmonella was found in cultures of semen. In this patient bacteriologic cure was obtained by use of trimethoprim-sulfamethoxazole obviating need for surgical extirpation of the infective focus as had been required in previously reported cases of salmonella epididymitis/orchitis.

Serum UDP-galactose: glycoprotein galactosyltransferase in diabetics with microangiopathy.

1. Levels of serum UDP-galactose:glycoprotein galactosyltransferase in 117 unselected diabetics were compared with those in 60 non-diabetic healthy controls. 2. Enzyme activity (mean +/- 2 S.D.) of control sera was found to be 90.2 +/- 21.5 etamoles/ml/hr at 37 degrees. In 30 of the 117 diabetic sera (26%) enzyme activity was elevated (greater than mean + 2 S.D. of the controls). Sixteen of 19 (84%) patients with retinopathy, 16 of 26 (62%) patients with peripheral vasculopathy and 13 of 26 (50%) patients with neuropathy had higher levels of serum enzyme. When serum enzyme levels of groups of diabetics with retinopathy, peripheral vasculopathy and neuropathy were compared with the enzyme level in all diabetics, there was a significant difference with p values of 0.001, 0.05 and 0.05 respectively.

Primary enuresis: relative success of three methods of treatment.

A total of 169 children with primary enuresis were treated by one of three methods--use of a special diet, imipramine, or a waking device (the Mozes detector). Of 64 who received the diet 1 (1.6%) was cured; of 62 who were treated with imipramine 13 (20.9%) were cured; and of 43 who used the detector 23 (53.5%) were cured. Results at follow-up remained substantially unchanged for cure. Improvement rate without cure during treatment was higher for the children treated with imipramine than for those treated with the detector, but at follow-up the reverse was true. Parents of children who received the special diet, because they were unimpressed by the rate of improvement, would not permit their children to continue this form of therapy for longer than 1 or 2 months.
