Mitral stenosis in a girl of five years.

Mitral stenosis(MS) detected below the age of 20 years is called juvenile mitral stenosis (JMS). JMS constitute 25-40 % of all cases of isolated mitral stenosis, though overall incidence of rheumatic fever and rheumatic heart disease (RHD) within mixed population is 7.5- 7.8 per thousand. The patient was 5 years old girl hailing from Modhupur, Tangail got herself admitted into CCU Mymensingh Medical College Hospital with the complaints of low grade fever, shortness of breath and also associated with failure to thrive. She was ill looking, mildly anaemic. Precordial examination revealed apex beat was in the left 5th intercostals space, tapping in nature, palpable P(2). There was left parasternal heave. 1st heart sound loud, pulmonary component of the 2nd heart sound was accentuated, opening snap with mid diastolic murmur with pre systolic accentuation. Routine blood examination reveals leucocytosis with raised ESR. C-reactive protein (CRP) and ASO titre were significantly raised. X-ray chest P/A view showing the features of mitral stenosis. Echocardiography showing MS (moderate) with pulmonary hypertension. She was treated with antibiotics and other relevant drugs and discharge with an advice for follow up and take preparation for cardiac intervention.

Angiographic severity and extent of coronary artery disease in patients with type 2 diabetes mellitus.

Coronary angiographic characteristics of fifty patients with type 2 diabetes mellitus and coronary artery disease (CAD) were compared with fifty non diabetic patients with CAD. Type 2 diabetic patients undergoing clinically indicated elective coronary angiography were individually matched with fifty non diabetic coronary artery disease patients for age, sex and major risk factors. No significant difference was present between the mean age, presenting complains and other coronary risk factors between the two groups. Severity and extent of coronary artery involvement was assessed by a coronary artery score (CAS) using the segmental distribution method for coronary artery lesions and morphometric analysis of atherosclerotic lesion was done. Type 2 diabetic patients had a higher CAS (11.74+/-5.04 vs 8.72+/-4.87; P<0.001) as compared to the non-diabetic patients. Multivessel disease were more prevalent in both the groups (82% vs 68%; P>0.05) but diabetic patients had significantly higher number of triple vessel disease (58% vs. 38%; P<0.001). Normal coronary arteries and single vessel disease were more prevalent in non-diabetic patients (32% vs. 18%; P<0.05). As compared to non-diabetic group diabetic patients had a higher total number of diseased vessels (78.66% vs. 68%; P<0.01), a higher lesion per patient ratio (3.94+/-1.80 vs 3+/-1.67:P<0.001) and more proximal lesions (40.83% vs. 34.70%; P>.05) though not statistically significant. Morphometric analysis of coronary artery lesions revealed that diabetic patients had significantly higher number of multiple irregularity lesions (24.37% vs. 15.33%; P<0.01) and lesions were more obstructive (lesion involving 70-90% of coronary lumen: 70.53.% vs. 57.33%; P<0.05). Though there was no significant difference between the systolic left ventricular function between the two groups but significant higher regional wall motion abnormality was found more in diabetic patients (76%vs 62%; P<0.01). So type 2 diabetic patients had more severe and extensive atherosclerotic lesion in their coronary arteries than the matched non diabetic control on coronary angiography suggesting an independent effect of diabetic mellitus on atherosclerotic process specially in our population.

Placebo controlled trial of methotrexate in systemic sclerosis.

Eighteen adult patients of systemic sclerosis were included in this prospective study from Rheumatology Clinic of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka during the period of July 1997 to December 1999 to observe the effectiveness of treatment with methotrexate (MTX) versus placebo. Among the eighteen patients 9 patients were randomly assigned to MTX and 9 to placebo therapy. Nine patients were dropped out (6 in placebo and 3 in the MTX group), because of toxicity and non-compliance. Clinical improvement following treatment was observed in 33.33% of the patient in MTX group but none in placebo group, but this difference was not statistically significant. Anorexia, nausea and occasional vomiting were common side effects in MTX group and subsided in most cases with the passage of time despite the continuation of therapy.

Budd-Chiari syndrome.

A 30 years old, non-alcoholic farmer from Trishal, Mymensingh was admitted in Mymensingh Medical College Hospital on 7 February, 2004 with the complaints of gradual swelling of abdomen, both legs and upper abdominal pain for 3 months. For the last 6 years, he was treated as a case of chronic liver disease (CLD) with spironolactone and frusemide. He was non-icteric, mildly anaemic with mild oedema, clubbing, gynaecomastia and engorged vein over anterior abdominal wall, flanks and back. Direction of venous flow was from below upward. There were mild hepatosplenomegaly, ascites and bilateral testicular atrophy. He was diagnosed as a case of Budd-Chiari Syndrome (BCS) on the basis of physical examination and it was confirmed by the findings of ultrasonography, liver scan and doppler study. The patient was managed by medical therapy alone.

Serum IL-2 in chronic hepatitis B virus infected patients and its association with disease activity.

Association of serum Interleukin -2 (IL-2) levels with the activity of chronic hepatitis B (CHB) was evaluated in this study. We studied 45 subjects in the Department of Hepatology, Bangabandhu Sheikh Mujib Medical University, Dhaka. They were divided into three groups. Group A consisted of 15 CHB patients with raised Alanine aminotrasferase (ALT) (> 80 iu/L), Group B consisted of 15 CHB carrier with normal ALT (< or =40 iu/L) and Group C consisted of 15 healthy subjects with normal ALT. Serum IL-2 level was measured in all groups. IL-2 level was detected in 14(93.33%) subjects in group A and 2(13.33%) subjects in group B. IL-2 level was undetectable in all the subjects in group C. The association between IL-2 level and activity of chronic hepatitis B was observed by statistical analysis (Z-test). There is significant difference between group A and group B (p<0.001) and also in group A and group C (p<0.001), but no significant difference between group B and group C (p>0.05). Our results support the observation that IL-2 level can be used as a marker of activity in CHB patients as IL-2 level was significantly detected in the patients of group A.

Lutembacher's Syndrome.

A 56 years old farmer from Churkhai, Mymensingh was admitted in Cardiology unit of Mymensingh Medical College Hospital 24 October, 2004 with the complaints of progressive breathlessness on exertion with the repeated respiratory tract infection. He had 3 episodes of multiple large joints swelling involving knee, ankle, wrist, during his childhood with spontaneous recovery without any residual deformity. At the age of 45 years, he was incidentally diagnosed as enlarged heart by a medical board, when applied for Foreign Service. In cardiology unit he was diagnosed as a case of Lutembacher's syndrome on the basis of history, physical examination and it was confirmed by X-Ray, ECG and Echocardiography study. As the patient developed pulmonary hypertension with calcified mitral valve leaflet so percutaneous transseptal mitral commissurotomy and or surgery is not indicated. So the patient was managed by medical therapy alone.

Questionnaire techniques in assessing acne handicap: reliability and validity study.

The purpose of this study was to examine and compare the reliability and validity of two acne-specific measures, the Cardiff Acne Disability Index (CADI), the Acne Disability Index (ADI) and a general health status instrument, the United Kingdom Sickness Impact Profile (UKSIP). The test-retest reliability was carried out for the UKSIP, ADI and CADI with an interval of 10 days in 70 patients with acne. The correlation coefficient for the overall UKSIP score was high (r = 0.99, p < 0.001) for the CADI was 0.96 (p < 0.001) and for the ADI was 0.98 (p < 0.001). Individual category score correlations in the UKSIP and ADI were greater than 0.83. Tests of internal consistency of the instruments scored highly. A further 100 patients with acne and 50 controls completed all three instruments. The overall UKSIP mean score of patients was 5.6 (sd = 4.7) and of controls was 0.45. The ADI mean patient score was 40.3%, controls 17.6%. The CADI mean patient score was 42.1%, controls 13.2%. The CADI was the only instrument that correlated with the clinical acne severity score (p < 0.05); the UKSIP score correlated with the CADI score (p < 0.05) but not with the ADI score. This study has established aspects of the reliability and validity of the UKSIP, the ADI and the CADI.

Dermatology Life Quality Index (DLQI)--a simple practical measure for routine clinical use.

A simple practical questionnaire technique for routine clinical use, the Dermatology Life Quality Index (DLQI) is described. One hundred and twenty patients with different skin diseases were asked about the impact of their disease and its treatment on their lives; a questionnaire, the DLQI, was developed based on their answers. The DLQI was then completed by 200 consecutive new patients attending a dermatology clinic. This study confirmed that atopic eczema, psoriasis and generalized pruritus have a greater impact on quality of life than acne, basal cell carcinomas and viral warts. The DLQI was also completed by 100 healthy volunteers; their mean score was very low (1.6%, s.d. 3.5) compared with the mean score for the dermatology patients (24.2%, s.d. 20.9). The reliability of the DLQI was examined in 53 patients using a 1 week test-retest method and reliability was found to be high (gamma s = 0.99).

Cyclosporin greatly improves the quality of life of adults with severe atopic dermatitis. A randomized, double-blind, placebo-controlled trial.

A multicentre, randomized, double-blind, controlled crossover clinical trial was conducted on 33 patients with severe refractory atopic dermatitis, to determine the effects of cyclosporin (5 mg/kg/day) on their health-related quality of life. Treatments were administered for 8-week periods. One group (n = 16) received placebo followed by cyclosporin, and the other (n = 17) received cyclosporin and then placebo. Health-related quality of life was assessed at 0, 8 and 16 weeks using a general measure, the United Kingdom Sickness Impact Profile (UKSIP), an eczema-specific measure, the Eczema Disability Index (EDI), and a global 5-point rating scale of overall health (very good to very poor). In addition, clinical assessments (i.e. extent and activity of disease) were made by the investigators. UKSIP and EDI scores indicated significant improvement in quality of life (P < 0.05-P < 0.01) of patients with atopic dermatitis after treatment with cyclosporin. Although no patient required withdrawal from the study, 20 patients receiving cyclosporin reported adverse events, compared with eight taking placebo. There was a close correlation (P < 0.05-P < 0.01) between the UKSIP and EDI scores. In contrast, there was either no correlation, or only a very poor correlation, between the quality of life parameters and clinical measures of extent and activity of eczema. When cyclosporin was stopped, relapse was rapid, but the mean scores for disease activity and extent of disease were less than their baseline values (i.e. an improvement of greater than 25% was maintained in 11 patients at week 4).(ABSTRACT TRUNCATED AT 250 WORDS)

Validation of Sickness Impact Profile and Psoriasis Disability Index in Psoriasis.

A prospective cross-sectional questionnaire study of 32 patients with psoriasis was carried out in order to validate the use of the Sickness Impact Profile (SIP) in psoriasis and compare its sensitivity with the Psoriasis Disability Index (PDI). Overall PDI scores, but not overall SIP scores, correlated well with PASI scores (P less than 0.05). There was good correlation between the PDI and overall SIP scores (P less than 0.01). Psychosocial factors are more severely impaired than physical activities in patients with psoriasis. It is now possible to directly compare the disability experienced by psoriatic patients with that experienced by patients suffering from other systemic diseases, using the SIP. The PDI is an appropriate method to give a rapid overall measure of psoriasis disability.
