Résumé
The study was under taken to detect mecA gene of methicillin resistant Staphylococcus aureus (MRSA) by PCR. It was carried out in the department of Microbiology, Mymensingh Medical College in collaboration with the Department of Medicine under the Faculty of Veterinary Science, Bangladesh Agricultural University, Mymensingh between the periods from July 2006 to June 2007. A total of 40 S. aureus strains were used in this study. Isolates of S. aureus were identified by standard microbiology technique and their antimicrobial susceptibility test was done by disk diffusion method according to NCCLS. Minimum inhibitory concentration (MIC) of oxacillin was determined for all isolates by standard agar plate dilution method. All strains were tested for mecA gene by PCR. Out of 40 S. aureus strains 15(37.5%) were detected as MRSA by disk diffusion and agar dilution method but 10(25%) yielded mecA gene by PCR. Detection rate of MRSA by disk diffusion and agar dilution test showed significant difference to that by PCR (p<0.001).
Résumé
Retinal vasculitis is one of the common causes of blindness among the young adult in this subcontinent. Causes of retinal vasculitis are variable and it is one of the common ocular manifestations of tuberculosis. This case control study was carried out on 45 patients with retinal vasculitis of different age groups. All the patients were purposively selected from the department of ophthalmology, Bangabandhu Sheikh Mujib Medical University and National Institute of Ophthalmology Dhaka. This study reveals that vasculitis retinae is a disease of younger age group (68.9%). Mean+/-SD age of cases were 31.84+/-10.82 years. It occurs more in male (75.6%) and male female ratio is 3.09:1, single or both eye may involve. Retinal vasculitis occurs more in middle socio-economic status persons (62.2%). It present with floaters (58.9%), hazy media (60%), vitreous haemorrhage (57.8%) and retinal haemorrhage (42.2%). All 45 subjects both cases and control groups were tested with Mantoux test. 18(40%) subjects of cases and 13(28.9%) subjects of control group were found positive Mantoux test. It was observed that the association of tuberculosis with vasculitis retinae is not statistically significant. As tuberculosis is common in this country, further specific and extensive study over a longer period of time is necessary for understanding the role of tuberculosis in retinal vasculitis patients.

In this ongoing prospective study conducted in University Cardiac Center, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from July 2004 to January 2006. Fifty (50) patients (mean age 56+/-7.2 years) underwent stentangioplasty were evaluated. The study group of 50 patients consisted of 42 (84%) men and 08 (16%) women. The aim of this study was to evaluate in-hospital success, failure and complications during the procedures. About risk factors 19(38%) had hypertension, 13(26%) were smoker, 11(22%) suffered from diabetes mellitus, 05(10%) had family history of ischaemic heart disease. Average left ventricular ejection fraction was 54+/-7. Target vessel percutaneous coronary angioplasty (PTCA) were done in 61 vessel, intracoronary stent implanted in 58 vessels, direct stenting were done in 35 cases, failed PTCA were in 03(6%) cases and two had dissection. The native vessels had a mean reference diameter of 2.91 mm and their luminal diameter increased significantly after percutaneous coronary intervention (PCI). All the patients were discharged by one to three days of the procedure with improvement of their clinical condition. In conclusion, intracoronary stent deployment in coronary artery stenosis following balloon angioplasty is a valid and beneficial strategy with good in-hospital results.

One thousand six hundred and ninety six males and females living in Dhaka city and a nearby village were grouped according to their age and occupation. The subjects blood pressure and occupation were recorded. The study revealed that occupation had a significant effect on both diastolic and systolic blood pressure, specially in relation to social status, Age, smoking, BMI appeared to modulate the blood pressure.
