Cherubism

Cherubism, a rare tumour like lesion, is characterised by bilateral, painless, firm jaw swellings with cherubic appearance of face. It affects children of both sexes and is often familial. A case of Cherubism is being reported here because of its rarity and first from this geographical area.

Vocal cord dysfunction presenting as refractory asthma

Vocal cord dysfunction is a rare variety of upper airway obstruction characterized by typical laryngoscopic features and may mimic an acute asthma attack. The case presented in this report pertains to a 15-year-old girl who had repeated acute episodes of dyspnoea and wheezing and remained non-responsive to corticosteroids and inhaled bronchodilators requiring endotracheal intubations for adequate control. Laryngoscopic findings were consistent with vocal cord dysfunction. She was treated with a tracheostomy and psychological support.     

Zinc supplementation as adjunct therapy in children with measles accompanied by pneumonia: a double-blind,randomized controlled trial

BACKGROUND: Zinc deficiency, common in developing countries, is associated with decreased immunocompetence. Zinc supplementation benefits children with acute and persistent diarrhea and prevents pneumonia. Most deaths from vaccine-preventable diseases are from measles and whooping cough; pneumonia is the most common complication of measles and often the proximate cause of related deaths. OBJECTIVE: We evaluated the effect of zinc supplementation on episodes of illness in children with measles accompanied by pneumonia. DESIGN: In a double-blind, randomized controlled trial, children aged 9 mo-15 y who were admitted to the Infectious Diseases Hospital in Calcutta with clinically severe measles accompanied by pneumonia and who had been ill for 相似文献   

Evaluation of downstaging in the detection of cervical neoplasia in Kolkata,India

Unaided visual inspection or "downstaging" has been suggested as a potential alternative method for cervical cancer screening in developing countries. Our study was designed to evaluate the accuracy of downstaging to detect cervical neoplasia in a low-resource setting. A total of 6,399 women aged 30-64 years were screened with downstaging by trained nonmedical health workers. Two thresholds were used to define positive downstaging: "low threshold" when any visible abnormality on the cervix was considered positive and "high threshold" when selected abnormalities such as bleeding on touch, bleeding erosion, hypertrophied oedematous cervix, congested stippled cervix and growth or ulcer constituted the positive test. All women underwent a colposcopy examination. Biopsies were directed when colposcopy revealed abnormal lesions. True disease status was defined as histologically proven moderate dysplasia and worse lesions. Since all the participants received a diagnostic (reference) investigation (biopsy and/or colposcopy), sensitivity, specificity and predictive values were estimated directly. Low- and high-threshold downstaging were positive in 1,585 (24.8%) and 460 (7.2%) women, respectively. The sensitivities of low- and high-threshold downstaging to detect high-grade precursors and invasive cancers were 48.9% and 31.9%, respectively. The specificities were 75.8% and 93.3%, respectively. These results indicate that downstaging is not suitable as an independent primary screening modality for cervical neoplasia.     

A molecular approach (multiplex polymerase chain reaction) for diagnosis of rhinosporidiosis

A New multiplex PCR have been developed in our laboratory using primer sets, aiming amplification of both D.N.A target fragments obtained in 18S RNA of commonly encountered fungi in human being and in Rhinosporidium seeberi using F1-fw/F2-rev (500 bp target) and Rhino-fw/ Rhino-rev (.177 bp target). This multiplex PCR has been found to be able to delect R. seeberi from clinical samples and differentiate it from other fungi. Furthermore, by this multiplex PCR, R. seeberi, phylogenitically appears to belong to a member of so called DRIPs clade of fish parasite not a cyanobacterium as claimed previously, by some workers.
