ABSTRACT
Background: Drug can cure ailment when used rationally on the other hand they may become harmful or even may threaten a life when used irrationally. Absence of guidelines for antibiotic use, protocols for rational therapeutics and infection control committees, have led to overuse and misuse of antimicrobials even in different specialized units in hospitals. Objective: The study has been designed to get a picture of use of antibiotics in a tertiary care hospital of Bangladesh. Materials and method: Cross sectional study was conducted in the department of Medicine of Sir Salimullah Medical College and Mitford Hospital, Dhaka, Bangladesh, for 3 months from 1st January 2009 to 31st March 2009. Admitted patients of Medicine unit-1 who got antibiotics were included in the study. Total number of patients was 1563. Results: Five hundred out of 1563 patients were prescribed antibiotics (38%). Out of 500 prescriptions, 68(14%) prescriptions were found irrational. Conclusion: Continuous surveillance should be carried out to reduce the irrational use of antibiotics.
ABSTRACT
Background: Giant cell tumour (GCT) is an aggressive and potentially malignant lesion. Microscopic feature reveals osteoclast like giant cells in a mononuclear stromal cells background. The mononuclear stromal cell is interpreted as neoplastic. Objective: As radiological diagnosis is non invasive and cost effective in comparison to histopathological diagnosis, considering the patients’ compliance, the aim of the study was to observe the diagnostic efficacy of radiology in diagnosis of GCT. Materials and method: This cross sectional study was carried out in the department of Pathology, Delta Hopital Ltd., Dhaka, Bangladesh from July 2011 to December 2012. A total of 30 study subjects were enrolled in the study irrespective of age and sex. Biopsy material and relevant data of clinically suspected cases of GCT along with radiology report were sent from National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh. Histopathological diagnosis was made by expert pathologists. Results: Mean (±SD) age of the study subjects was 29.20 (±7.34) years with highest number of patients were observed in 3rd decade and female was predominant (60%) with a male female ratio of 1:1.5. Common site of GCT was around knee (50%). Among 30 clinically diagnosed GCT, 25 (83.3%) cases were radiologically diagnosed as GCT, 2 (6.7%) diagnosed as fibrous dysplasia, 1 (3.3%) as chondroblastoma, 1 (3.3%) as simple bone cyst and 1 (3.3%) as aneurysmal bone cyst. However among 30 clinically diagnosed GCT, 28 (93.3%) patients were histopathologically diagnosed as Giant cell lesion and rest 2 (6.7%) patients diagnosed as fibrous dysplasia. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of radiological diagnosis of GCT were found to be 92.6%, 100.0%, 100.0%, 40.0% and 90.0%, respectively. Conclusion: Radiology can be effectively used as a screening tool in diagnosing GCT.
ABSTRACT
Background: Lymph node enlargement presents a clinical problem whose significance can range from trivial to critical, depending on the cause of lymphadenopathy. Diseases involving the lymph node fall primarily into three categories, which include lymphadenitis, metastatic malignancies, malignant lymphoma. It is not feasible to excise every enlarge lymph node. So clinical selection of patients must take place and diagnosis of definite causes of lymphadenopathy by histological examination is essential for appropriate treatment. Objective: The aim was to find the relation and association of proportion of different types of lymphadenopathy with age and gender. Materials and method: This cross sectional study was done in Delta Hospital Limited, Dhaka, Bangladesh during the period of May 2010 to December 2010. A total 88 cases were studied irrespective of age, sex along with clinical diagnosis. Results: Among the study subjects 55.7% was being benign lesions and remaining were with malignant lesions. Among the benign lesions majority (31.8%) were tuberculosis with female predominance which commonly occurs below the age of 20 years, where as non-Hodgkin’s lymphoma (33.3%) was the commoner form among malignant cases with male predominance occurs in older age group. Mean (±) age of benign and malignant cases was 22.1 (±12.73) years and 44.1 (±17.37) years respectively. Conclusion: The present study revealed that lymphadenopathy occurs more commonly in the middle age group with predominance of benign lesions. Among the benign lesions tuberculosis is the most common one and non-Hodgkin’s lymphoma is the commonest malignant lesion.
