Background: Diabetic ketoacidosis (DKA) is an acute metabolic complication of diabetes mellitus (DM). It may be the presenting feature in type 1 DM, but more commonly it complicates previously diagnosed diabetic patients, both type 1 and type 2. If not recognized early and treated in a judicious way the outcome is often fatal. Objectives: The objectives of this study was to see the common presenting features of DKA, their precipitating causes, patterns of electrolyte imbalance, treatment requirement in early hours and to see the outcome. Materials and methods: This cross sectional study was done in BIRDEM General Hospital on fifty adult patients who presented with DKA over a period of nine months (January 2007 to September 2007). Results: Total number of patients were 50, male were 24 and female were 26 (M:F =12:13). Mean age was 27.6 ± 3.7 years. The incidence of DKA was more in known diabetic patients (32, 64%), in comparison with new cases (18, 36%). Frequency was more in poor village people (31, 62%). Vomiting (24, 48%) was the most frequent complaint, followed by fever (19, 38%), nausea (16, 32%), abdominal pain (14, 28%), weakness (13, 26%), polyuria (12, 24%) and polydypsia ( 8, 16%). Infection (18, 36%) was the most common precipitating cause, closely followed by inadherence to insulin therapy (17, 34%). In 12 (24%) cases no cause could be identified. Glycaemic control was poor, HbA1c was >7% in 98% cases. Severe acidosis (pH < 7) was less common (4, 8%) and gross electrolyte imbalance was uncommon but all patients required potassium supplementation in course of treatment. Neutrophilic leukocytosis was present in 44 (88%) cases, irrespective of presence of infection. Mortality was low (3, 6%). Conclusion: Diagnosis and treatment of DKA is not difficult if recognized early. So, high index of suspicion is necessary, particularly in previously undiagnosed cases.

Objectives: To describe the prevalence of depression among post-graduate medical students and to evaluate some related risk factors.Methodology: This cross-sectional survey was done in three post-graduate medical teaching institutes in Dhaka, Bangladesh in February 2013. A preformed questionnaire including some demographic, socio-economic and work related variables was used for the purpose and depression was diagnosed and severity assessed by using Hamilton Rating Scale for Depression (HAM-D).Results: A total of 100 post-graduate medical trainees were given a preformed questionnaire. Among them 53 students filled it up properly and sent back in given time (response rate was 53%

Extensively drug-resistant (XDR) tuberculosis is defined as disease caused by Mycobacterium tuberculosis with resistance to at least isoniazid and rifampicin, any fluoroquinolone, and at least one of three injectable secondline drugs (amikacin, capreomycin, or kanamycin). This definition in immensely valuable for more uniform surveillance in varied international settings. The prevalence of tuberculosis drug resistance has risen to the highest rate ever recorded. Although the gold standard for drugsusceptibility testing has been the agar proportion method; due to it’s time consumption, more sensitive, specific and rapid diagnostic tests are required. It is difficult to differentiate XDR tuberculosis from non-XDR tuberculosis clinically, although the former is associated with greater morbidity and mortality. The treatment of XDR tuberculosis should include agents to which the organism is susceptible, and should continue for a minimum of 18-24 months. However, treatment continues to be limited in tuberculosisendemic countries largely because of weaknesses in national tuberculosis health-care models. The ultimate strategy to control drug-resistant tuberculosis is one that implements a comprehensive approach incorporating innovation from the political, social, economic, and scientific realms.
