Exercise and anxiety neurosis: comparison of patients with and without mitral valve prolapse.

It has been hypothesized that mitral valve prolapse may account for a substantial number of patients who have symptoms of chronic anxiety neurosis. In a previous investigation, this hypothesis was confirmed in eight of 21 patients who had anxiety neurosis. In the present investigation, we reevaluated the hypothesis that persons with anxiety neurosis have impaired exercise ability by exercising 20 of the anxiety neurotics according to a standard treadmill exercise protocol. Compared with the control group, the anxiety neurotics required less exercise to achieve an equivalent heart rate and therefore their estimated maximum oxygen consumption was less, thus confirming the hypothesis. However, this difference was due entirely to the anxiety neurotics with mitral valve prolapse, and those without prolapse did not differ significantly from the controls. This suggests that impaired exercise tolerance in anxiety neurotics may be attributable to a subgroup of these patients with mitral valve prolapse.

Neonatal citrobacter sepsis: clinical and epidemiological aspects.

Fourteen neonates were diagnosed to have Citrobacter sepsis during 1986-89, representing 4.6% of all cases with bacteriologically proven sepsis. Most of these infants were low birth weight (mean 2046 gm, +/- 750) and preterm (mean 34.8 weeks, +/- 3.8). Mean age at onset of sepsis was five days. In 10 cases the hematological profile was suggestive of sepsis. Infants had clinical evidence of multisystem infection; 2 with septic arthritis and 3 meningitis. The case fatality rate was 61%. Resistance to antibiotics was frequent. Citrobacter species were also cultured from other sites: umbilical stumps, eye swabs, urine, skin pustules and umbilical catheter tips. The epidemiological features and virulence of this organism call for vigilance and strict control measures.

Rotavirus and bacterial enteropathogens causing acute diarrhea.

The etiology of rotavirus in acute diarrhoeal illness in children 0-5 years of age, admitted to the Pediatric wards of Kasturba Medical College Hospital, Manipal was studied, over a period of one year. Rotavirus in the faecal samples detected by the slide latex agglutination test accounted for 14.9% of the diarrheas with maximum incidence in the 7-12 months of age group (57.5%). Bacterial enteropathogens continued to play a significant role in diarrheal diseases. Salmonella enteritis was found more in the age group 0-6 months and shigellosis in 37-60 months. In a control study of 100 children who had no diarrhea, 2 were found positive for rotaviruses.
