Case ReportsPrimary papillary carcinoma of the thyroglossal duct cyst--a case report.
Thyroglossal duct cyst is the most common developmental anomaly of the thyroid gland, presenting as a mid line neck swelling. Malignancy arising in them is a rare event, with papillary thyroid carcinoma being the commonest. Thyroglossal duct cyst carcinomas are usually asymptomatic and are not suspected preoperatively in most instances, hence the need for surgical excision and careful pathological examination of these cysts. ⋯ The thyroid gland was normal. Histological examination of the excised cyst showed a papillary thyroid carcinoma arising in the thyroglossal duct cyst. Long term survival of patients with thyroglossal duct cyst carcinoma is excellent.

The bone marrow examination is invaluable in the diagnosis of certain haematological and non haematological conditions. The diagnosis of haematological disorders is achieved mainly by the examination of peripheral blood and bone marrow aspirate smears. Although bone marrow histology can provide additional information, for many technical reasons, trephines are not so popular and their diagnostic value is overlooked. ⋯ All the bone marrow biopsies performed at the St. John's Medical College Hospital over the last 12 years (1990-2002) were reviewed The bone marrow biopsies were grouped into 3 categories for analysis. The trephine biopsy is invaluable in cases where the aspirate fails or is a dry tap as in the case of myelofibrosis, focal marrow involvement as in granulomatous lesions, metastatic tumour and lymphomas.

RET mutation status in medullary thyroid cancer(MTC) patients and the significance of genetic screening for mutations in their immediate relatives--a preliminary report.
Multiple Endocrine Neoplasia (MEN) 2A is an inherited disease characterized by the development of medullary thyroid carcinoma (MTC), pheochromocytoma(PHCH) and hyperparathyroidism(HPT). It has recently been shown to be associated with germline mutations in the RET proto-oncogene. Genetic testing for RET mutations will, therefore allow the identification of people with asymptomatic MEN 2 who can be offered prophylactic thyroidectomy and biochemical screening as preventive measures. ⋯ Germline mutations were identified in 3 of 4 MEN 2A patients, 18 of 24 sporadic MTC(SMTC), 2 of 4 children of MEN2A and 8 relatives of SMTC. Common mutation was in exon 10 and 11 (c634). It is recommended that RET mutation analysis and counseling of patients and their immediate relatives be introduced on a regular basis to identify gene carriers.

Extended spectrum b lactamases (ESBL) in clinical isolates of Klebsiella pneumoniae and Escherichia coli.
The present study was conducted to find the prevalence of Extended spectrum b Lactamase (ESBL) producing strains of Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli (E. Coli) in different clinical samples received at the Department of Microbiology, Medical College Baroda. A total of 187 clinical isolates (106 of K. pneumoniae and 81 of E. ⋯ ESBL was detected in 53 isolates (33 K. pneumoniae and 20 E. coli). Using the interpretative guidelines of the NCCLS, 24% to 27% of the ESBL isolates would have been reported to be susceptible to the 3GC by routine antimicrobial susceptibility methods. DDST was found to be a useful, simple and cost effective test for the detection of ESBL producing strains.
