Mebendazole retention enema for severe Trichuris trichiura (whipworm) infection: a case report

The authors report a case of massive Trichuris trichiura infection, resulting in severe anaemia and congestive cardiac failure in a 9-year-old Iban boy, who was resistant to the usual oral anthelmintic treatment, but promptly responded to mebendazole retention enema. This patient also had an associated Entamoeba histolytica infection.     

Present phage types and antibiotic susceptibility of salmonellae.

A total of 168 strains of Salmonella were isolated in the Command Pathology Laboratory (WC) Delhi Cantt during the year 1990. Out of this, 143 were Salmonella typhi, 17 Salmonella paratyphi A, 7 Salmonella typhimurium and 1 Salmonella manhattan. The commonest phage type and biotype of Salmonella typhi was type E1 and type 1 respectively. The dominant biotype of Salmonella paratyphi A was type I. There was a very high degree of multidrug resistance of most of the strains. But all the strains were sensitive to ciprofloxacin and norfloxacin.     

Does malnutrition predispose to diarrhoea during childhood? Evidence from a longitudinal study in Matlab, Bangladesh

It is posited that diarrhoeal illness during one period has influence on diarrhoeal illness in a subsequent period. This relationship may potentially mask the association between malnutrition and subsequent diarrhoea. To test this, we analysed data on cross-sectional anthropometry in combination with data on diarrhoeal morbidity collected longitudinally in a community-based study of 1262 children (aged 6-60 months) during March-December, 1976, in Matlab, Bangladesh. The results confirmed the posited relationship between diarrhoeal morbidities in two consecutive periods and showed that the risks of diarrhoeal attack and longer diarrhoeal illness increased more than threefold during the 2 months following diarrhoeal illness during the preceding 2 months (previous diarrhoea). Children with no previous diarrhoea indicated a positive association between malnutrition and subsequent diarrhoea, but the pattern found among children with previous diarrhoea was not understandable. Logistic regression analyses performed separately for younger and older children showed that controlling for effects of previous diarrhoea, maternal illiteracy and household poverty, severe malnutrition as assessed by weight-for-age was found to be strongly associated with the risk of longer diarrhoeal illness in a 2-month interval in the age group 24-60 months; in the same age group the association with the risk of diarrhoeal attack was significant at the 10 per cent level. No such association for malnutrition, however, was found in the age group 6-23 months.     

Drug mixture which improves survival of ischemic rabbit epigastric skin flaps

The chief aim of this study was to maximize flap survival by counteracting the pathophysiological changes occurring during ischemia-reperfusion. Rabbit epigastric skin flaps given 21 hours of ischemia were infused intra-arterially with selected drugs at the start of reperfusion. Compared with control infused ischemic flaps, which had a 33% survival rate on day 7 post-ischemia, significant improvement was found with vasodilators nitrendipine (61%) and prostacyclin (65%) and the thrombolytic agent urokinase (65%); marginal improvement with the free radical scavenger desferrioxamine (53%); but no change with streptokinase (44%), heparin (21%), and ATP-MgCl₂ (35%). A drug mixture comprising all of these agents except streptokinase and urokinase produced 87% survival, suggesting an additive effect. Biochemical assays on skin homogenates and blood implicated oxygen free radicals, neutrophil infiltration, and thromboxane in flap failure. These results imply that multiple factors are responsible for ischemic flap failure and that a mixture of drugs needs to be infused to counteract all of the detrimental changes. © 1994 Wiley-Liss, Inc.     

Application of adjunct techniques in cytologic material in the diagnosis of rhabdomyosarcoma: case report and review of the literature

A 4(1/2)-yr-old female presented with right-sided pleural effusion and a retroperitoneal mass. Cytologic analysis of the pleural fluid yielded malignant small round blue cells, which were noncohesive, 3-4 times the size of lymphocytes. The malignant cells had hyperchromatic, pleomorphic nuclei with moderate amounts of vacuolated cytoplasm. A few fiber-shaped cells were also seen. Immunostains for desmin, muscle-specific actin were positive; ultrastructural findings of thick and thin actin-myosin filaments confirmed the diagnosis of embryonal rhabdomyosarcoma. This case illustrates the importance of performing appropriate immunohistochemical stains and ultrastructural studies on cytological material to arrive at a definitive diagnosis.     

FNAC diagnosis of tuberculosis--an eight years study at Mangalore

1. FNAC is a very useful adjunct in the diagnosis of tuberculosis: 2. Diagnosis of tuberculosis can be made by the demonstration of epithelioid granulomas with or without caseation even in the absence of AFB. 3. Necrotic features whether acellular or accompanied by neutrophilic infiltrate are usually misdiagnosed as suppurative abscesses. Such smears however show high AFB positivity and thus the diagnosis of tuberculosis is still possible even in the absence of epithelioid granulomas. 4. Therefore all smears obtained by FNAC of suspected tuberculous lesions should be subjected to ZN staining for AFB.     

Urological injuries during obstetric and gynaecological surgical procedures

Urological injuries during obstetric and gynaecological operations carried out between Jan. '88 to Dec. '88, at a hospital involved in resident teaching programmes were analysed retrospectively. Each case was reviewed for predisposing factors, location and type of injury, time and method of recognition and management. Fifteen injuries were documented in 892 gynaecological procedures and 296 obstetric procedures. Twelve injuries occurred during gynaecological operations whereas 3 occurred during obstetric operations. Thirteen were bladder injuries and two were ureteric injuries. Infiltrating carcinoma of cervix, pelvic adhesions, adhesions because of previous operations and distorted anatomy, were the important risk factors.
