C-reactive protein and buffy coat smear in early diagnosis of childhood septicemia.

Out of 200 cases of septicemia in children (age group 0-14 years), 111 had positive C-Reactive Protein (CRP > 12 mg/l) and 84 were buffy coat smear positive. Blood culture was positive in 98 cases, with predominant organism being Klebsiella pneumoniae, followed by Staphylococcus aureus. CRP test showed 100% sensitivity and 87.3% specificity, while buffy coat smear showed 76.5% sensitivity and 91.2% specificity. As blood culture reports are not available before 48-72 hours, combination of CRP test and buffy coat smear examination will be very helpful in early diagnosis of childhood septicemia.

Investigation with chitosan-oxalate oxidase-catalase conjugate for degrading oxalate from hyperoxaluric rat chyme.

Enteric hyperoxaluria manifests due to hyperabsorption of dietary oxalate, secondary to a variety of chronic gastrointestinal disorders. The potential use of chitosan immobilized oxalate oxidase-catalase conjugate to deplete the oxalate content of food materials, while they are in the digestive tract has been evaluated by treating rat stomach chyme with such an enzyme preparation. Oxalate oxidase, obtained from beet stem, was adsorbed on chitosan along with catalase and then cross linked with glutaraldehyde to stabilize the derivative. This chemical modification of oxalate oxidase brought about a shift in its optimal pH from 4.2 to 3.8 with a marginal increase in its K(m). Compared to native enzyme, the modified oxalate oxidase exhibited increased storage stability, higher thermal stability and enhanced resistance to proteolytic digestion and heavy metal inactivation. These improved properties of the immobilized oxalate oxidase possibly render it suitable for oral administration under hyperoxaluric conditions.

Acute iron poisoning.

Accidental iron ingestion is not uncommon in children and has become a leading cause of unintentional pharmaceutical ingestion fatality. Difficulty in obtaining urgent serum iron levels in majority of hospitals in India, lack of objective indices for starting and stopping the chelation therapy and the cost of chelation therapy, all pose a significant challenge for a clinician in managing an acutely intoxicated patient. This review emphasizes the need for early recognition and correct intervention of a child with acute iron overdose to avoid undue morbidity and mortality.

Melioidosis--rare or overlooked?

The word melioidosis conjures images of a rare, exotic disease meant only for large textbooks of pediatrics, to be read only to be forgotten or even to be ignored completely. The following two cases of melioidosis from India will surely serve as an eye opener.

Lactation management clinic-positive reinforcement to hospital breastfeeding practices.

Supportive breastfeeding policies in the hospital constitute the foundation for initiation of successful breastfeeding by mothers, constant reinforcement and support to all lactating mothers is however essential to maintain lactation. The objective, methodology and outcome of the Lactation Management Clinic which constitutes a hospital-based mother support group is described. The study was carried out over a period of 2 1/2 years and 519 mothers had attended this clinic. Analysis of the data revealed that at the time of the 1st visit to the clinic, 65.9% mothers had already started supplementary top feeds and the commonest reason encountered was mother's own assessment of inadequate milk seen in 73.6% mothers. Two-thirds (66.9%) of babies in our study were roomed in right from the first day of life, 75.3% of babies had received colostrum and 67.1% babies had not received any prelacteal feeds and yet faced problems at lactation. Mother and infant evaluation revealed no complications with 86.5% mothers and with 54.5% babies. Local breast problems were detected in 19.3% mothers. Faulty positioning was observed in 47.2% patients. Psychological support to mothers was the most important form of therapy given. Seventy eight per cent mothers practiced exclusive breastfeeding subsequently while 21.2% of mothers were partially successful in lactation. Only 3 mothers had lactation failure.

Opinion survey of physicians on ethical issues in medical research.

A total of 3622 physicians registered in the Association of Physicians of India were contacted through mail and requested to respond to a semistructured questionnaire pertaining to different aspects of medical ethics, with particular focus on informed consent. Six hundred twenty-nine physicians (17.4%) responded to the questionnaire; 86% of the respondents reported having had no formal training in medical ethics; 49% of the subjects who undertook research obtained oral consent only. Majority of the respondents noted the relevance of ethics in different medical situations, though in certain areas like community health and research using animals ethical issues were felt to be less important. Patients' inability to come for regular follow-up and illiteracy were opined to be the main constraints in obtaining consent. Opinion on the amount of information to be imported to research participants as part of informed consent was at variance with standard guidelines. Physicians who reported having had an orientation course in medical ethics and those with prior research experience were more aware of ethical issues. Majority of the professionals desired for inclusion of ethics in medical curriculum.
