Management of bio-medical waste: awareness and practices in a district of Gujarat

With the objective of assessing the level of awareness about the various aspects of biomedical waste and disposal practices by the medical practitioners this study was conducted. It was a cross sectional study. 30 hospitals with more than 30 beds minimum were randomly selected from Sabarkantha district, Gujarat. The doctors and auxiliary staff of those 30 hospitals were the study population. While all the doctors knew about the existence of the law related to biomedical waste but details were not known. Doctors were aware of risk of HIV and Hepatitis B and C, whereas auxiliary staff (ward boys, ayabens, sweepers) had very poor knowledge about it. There was no effective waste segregation, collection, transportation and disposal system at any hospital in the district. There is an immediate and urgent need to train and educate all doctors and the staff to adopt an effective waste management practices.     

A case of giant nasal pyogenic granuloma gravidarum

Pyogenic granuloma gravidarum occurs as oral or nasal lesions in approximately 5% of pregnant women. Nasal mucosa is an unusual site for this lesion with few cases reported in the literature. A case of giant nasal pyogenic granuloma gravidarum that required radical excision through an open rhinotomy after superselective embolization is described. The patient had a good cosmetic result and a satisfactory airway when she was seen for follow-up 1 year after surgery. Giant pyogenic granuloma gravidarum is best managed with a multidisciplinary approach involving radical excision after preoperative superselective embolization for safe and complete removal of the lesion.     

Do cyclooxygenase-2 knockout mice have primary hyperparathyroidism?

The absence of cyclooxygenase-2 (COX-2) activity in vitro reduces differentiation of both bone-forming and bone-resorbing cells. To examine the balance of COX-2 effects on bone in vivo, we studied COX-2 knockout (KO) and wild-type (WT) mice. After weaning, KO mice died 4 times faster than WT mice, consistent with reports of progressive renal failure in KO mice. Among KO mice killed at 4 months of age, some had renal failure with marked secondary hyperparathyroidism, but others appeared healthy. On the assumption that renal failure was not inevitable in COX-2 KO mice and that phenotypic differences might increase with age, we studied KO mice surviving to 10 months of age with serum creatinine levels similar to those of WT mice. In 10-month-old male KO mice, serum calcium and PTH, but not phosphorus, levels were increased compared with those in WT mice. 1,25-Dihydroxyvitamin D(3) levels were markedly elevated in KO mice. Skeletal analysis showed small nonsignificant decreases in cortical bone density by BMD and either an increase (distal femur, by microcomputed tomography) or no difference (distal femur, by static histomorphometry) in trabecular bone density in KO mice. There was a trend toward increased percent osteoblastic and osteoclastic surfaces, and on dynamic histomorphometry, the rates of trabecular bone formation and mineral apposition were increased in KO mice relative to WT mice. Similar trends were observed for most parameters in 10-month-old female COX-2 KO mice. However, rates of trabecular bone formation and mineral apposition were increased in 10-month-old WT females compared with males and did not increase further in female KO mice. These data suggest that COX-2 KO mice with intact renal function have primary hyperparathyroidism, and that effects of increased PTH and 1,25-dihydroxyvitamin D(3) to increase bone turnover may compensate for the absence of COX-2.     

STEP: an intervention to address the issue of stigma related to leprosy in Southern Nepal

This paper focuses primarily on the extent to which a Stigma Elimination Programme (STEP) affected the social participation of people affected by leprosy in southern Nepal. The Participation Scale (popularly known as The P Scale) was applied to compare leprosy affected people who participated in STEP groups with a control group comprising leprosy affected people who lived in villages where STEP had not been implemented. It was found that STEP participants had significantly higher levels of participation compared with controls and that their levels of social participation were higher than would be expected even for the general population. It was also found that leprosy affected people without visible deformity or ulceration (whether in the STEP group or not) do not appear to suffer participation restriction in southern Nepal.     

Sensory innervation of normal and hypospadiac prepuce: possible implications in hypospadiology

Sensory innervation of the skin influences wound healing through the release of neuropeptides from the nerve endings. The purpose of this study was to investigate the differences in the sensory innervation of the normal and the hypospadiac prepuce. The prepuce from 10 healthy children undergoing routine circumcision and 10 age-matched children undergoing hypospadias repair were submitted for immunohistochemistry, using antibodies against protein gene product (PGP) 9.5, calcitonin gene-related peptide (CGRP), and substance P (SP). The hypospadiac prepuce was found to be hypo-innervated for PGP 9.5 and CGRP positive nerves when compared with the normal prepuce (p<0.05). The number of SP-positive nerves were increased in the hypospadiac prepuce, but not to statistical significance (p=0.06, confidence interval >95%). There may be differences in the sensory innervation of the normal and hypospadiac prepuce. These differences in tissue environment may partly explain the postoperative edema, poor wound healing leading to urethrocutaneous fistula (UF), and increased analgesia requirements in patients undergoing hypospadias surgery.     

Review of dietary recommendations for diabetes mellitus

Previous nutritional guidelines for people with diabetes focused on carbohydrate-based meal planning. Updated guidelines from Europe and North America reflect a more flexible approach to nutritional intervention. New aspects of these most recent recommendations include: (1) increased emphasis on the role of trained dietitians for educating people with diabetes; (2) greater individualization of dietary choices based on cultural, regional and personal preferences; (3) more flexibility for choosing between carbohydrate and monounsaturated fat consumption, but with limitations on intake of polyunsaturated fats (<10% of total energy); (4) broadened allowance of sucrose in the diet (up to 10% of total energy); and (5) greater recognition of physical activity as an important means to control weight and enhance general health. Expert guidelines vary regarding preferential intake of carbohydrates with lower glycemic indices.     

Intra-articular dislocation of the patella with incomplete rotation--two case reports and a review of the literature

Intra-articular dislocation of the patella is a rare clinical condition. Only forty-five cases have been reported. Most of them were encountered in adolescents and required an open reduction. We report two cases in an older age group with an incomplete rotation of the patella, which were successfully treated by closed reduction. We discuss the literature and suggest that the management depends on the degree of patellar rotation.     

Diastolic heart failure: recognition, diagnosis and management

A variety of community-based epidemiological studies have suggested that 30-50% of patients with heart failure symptoms appear to have preserved left ventricular (LV) systolic function when assessed by echocardiography or similar techniques suggesting 'diastolic heart failure' (DHF) as its cause. The prognosis of these patients is characterised by morbidity and mortality similar to, but less overt than, patients with systolic dysfunction. However, rates of readmission for symptom control are broadly similar in patients with DHF or in those with systolic impairment. Thus, there are many similarities in the portrayal of both systolic and DHF but equally; there are also many key differences. Certainly, while there are several successful therapies for patients with systolic heart failure, the management of patients with DHF is poorly defined. In this review, the gaps in current knowledge and practice, which is creating this therapeutic void will be addressed.
