Lactation failure.

Seventy five mothers with lactation failure were studied, whose less than 4-month-old babies were admitted to the hospital. Partial lactational failure (94.7%) was noted more often than complete lactational failure (5.3%). Initiation of breastfeeding was delayed for 2 to 5 days usually for traditional reasons (77.3%) and because the mothers felt that the milk output was inadequate (92%). The various causes of lactation failure were determined and the relationship to various factors was analyzed. The commonest cause of lactation failure was insufficient milk or no milk (80%). The age, parity, education, socio-economic status, religion, family structure and urban vs rural status of mother--all had a bearing on the occurrence of lactation failure. An attempt was made to relactate all these mothers. The outcome was successful in 69.3 cases and failed in only 4% cases. In 26.7% cases, we cannot predict the outcome as the mothers hospital stay was very brief with no follow up.

A phase I study of a combination of allopurinol, 5-fluorouracil and leucovorin followed by hydroxyurea in patients with advanced gastrointestinal and breast cancer.

Twenty patients with advanced carcinomas of the colorectum, pancreas, stomach, and breast were enrolled in a Phase I study of a sequential administration of 5-fluorouracil-leucovorin (FU-LV) combination followed by hydroxyurea (HU) with allopurinol protection (HALF regimen). As a weekly regimen for 6 weeks, followed by a rest period of 2 weeks, FU was administered intravenously (i.v.) during infusion of a 2-hour i.v. infusion of LV at a dose of 500 mg/m2. Six hours following the FU-LV combination, HU (1 gm/m2) was administered orally. Allopurinol (300 mg every 8 hours, orally) was given the day before and on the day of the administration of the FU-LV combination. The starting dose of FU was 300 mg/m2, with escalations to 900 mg/m2. Mucositis, diarrhea, and hematologic toxicities were mild and sporadic with FU doses up to 750 mg/m2 and occurred in patients who had received prior treatment with FU and/or radiotherapy. Dose-limiting neurocerebellar toxicity was observed in 2 out of 6 patients who received a FU dose of 900 mg/m2. Three additional patients experienced moderate neuromotor toxicity at this dose level. Among 17 patients evaluable for response, partial responses were seen in 3 of the 9 patients with colorectal cancer, 1 of the 3 patients each with carcinoma of breast and pancreas. Three of the 5 responses occurred in patients who had received prior treatment with FU and/or radiation therapy. An FU dose of 750 mg/m2 is recommended for a Phase II trial of the HALF regimen.

Cystic fibrosis: scoring system with thin-section CT.

The progression of lung disease in patients with cystic fibrosis (CF) was evaluated with chest radiography. The severity and extent of the various radiographic changes were scored with the Chrispin or the Birmingham method, which involves the use of imprecise and subjective terms, such as line shadows, large pulmonary shadows, and nodular cystic lesions. Although computed tomography (CT) has been shown to be helpful in the evaluation of lung disease in CF, no scoring system or other objective criteria have been developed for the evaluation of the wide range of pulmonary changes in these patients. A CT scoring system was devised that incorporates all of the changes seen in the lungs of patients with CF. Such a scoring system may facilitate objective evaluation of existing and newly developed therapeutic regimens and may be a valuable tool in the preoperative evaluation of patients being considered for lobectomy or bullectomy and in the selection of patients for lung transplantation.

Poliomyelitis with special reference to immunization status.

One hundred ninety one children below 5 years of age suffering from poliomyelitis were analyzed to find out the immunization status and its correlation with the incidence of poliomyelitis. Effects of age, sex, immunization status and seasonal variation on the morbidity and mortality status were studied. The maximum number of cases were admitted during the months of July (23.6%) and August (23.1%). Of 191 cases, 143 (74.9%) had no immunization and 48 (25.1%) were partially immunized. A total of 155 (81.2%) cases had spinal polio, 23 (12.01%) bulbo-spinal polio, and 13 had (6.8%) bulbar polio. Serious illness (bulbospinal and bulbar type) was more in partially immunized children (25%) as compared to unimmunized children (16.8%). The mortality rate was more than two times higher in the partially immunized (29.6%) as compared to unimmunized children (11.2%). The possible explanation for high mortality in partially immunized children could be due to the adverse effect of OPV which has not been studied so far.

High resolution computed tomography in early scleroderma lung disease.

Seventeen patients with early systemic sclerosis (SSc) underwent high resolution computed tomography (HRCT) of the chest to evaluate dyspnea and/or abnormal pulmonary function tests (PFT). All patients were assigned a dyspnea score and each had routine chest radiography (CXR). Bronchoalveolar lavage (BAL) was performed on 10 patients. HRCT was abnormal in 15 patients (88%), while CXR was abnormal in only 10 patients (59%). Mediastinal lymphadenopathy was detected in 7 patients (41%). Disease duration, dyspnea score, and forced vital capacity (FVC) did not correlate with HRCT score. However, trends toward higher total BAL cell counts and higher BAL neutrophil counts were noted in patients with ground glass opacities on HRCT, and BAL lymphocyte counts were significantly higher in such cases. HRCT is superior to CXR for detecting early interstitial lung disease in SSc, but patient history and FVC correlate poorly with HRCT findings. Ground glass opacities on HRCT may reflect active alveolitis, and mediastinal lymphadenopathy associated with SSc lung disease may be a consequence of pulmonary inflammation.

Hepatitis B virus infection and its transmission in preschool children.

In the present study, 2.5% of 367 preschool children has HBsAg positivity. Of 11 mothers who were HBsAg positive during the third trimester of pregnancy, 4 had babies (36.4%) who developed HBsAg positivity by 2.5-3 months of age (vertical transmission). Two babies born of HBsAg negative mothers, with history of jaundice during first trimester, were HBsAg negative. All the relatives of HBsAg positive cases screened were negative for HBsAg.

Lung hernia: radiographic features.

Lung hernia is an abnormal protrusion of the lung beyond the confines of the thoracic cage. Hernias are classified as cervical, intercostal, or diaphragmatic. Each of these types can be either congenital or acquired. Acquired hernias can be spontaneous, posttraumatic, or pathologic as a result of a neoplastic or inflammatory process. This report describes five cases of lung hernias. Two were congenital cervical hernias, detected as incidental findings on chest radiographs of infants. One was a posttraumatic intercostal hernia detected on a chest radiograph and confirmed with CT. The remaining two were acquired intercostal hernias at the site of prior chest-tube drainage of tuberculous empyemas. Although both of these were clearly shown on CT scans, only one was visible on chest radiographs.
