RESUMEN

Nearly a century ago it was recognized that radiation absorption by stellar matter controls the internal temperature profiles within stars. Laboratory opacity measurements, however, have never been performed at stellar interior conditions, introducing uncertainties in stellar models. A particular problem arose when refined photosphere spectral analysis led to reductions of 30-50 per cent in the inferred amounts of carbon, nitrogen and oxygen in the Sun. Standard solar models using the revised element abundances disagree with helioseismic observations that determine the internal solar structure using acoustic oscillations. This could be resolved if the true mean opacity for the solar interior matter were roughly 15 per cent higher than predicted, because increased opacity compensates for the decreased element abundances. Iron accounts for a quarter of the total opacity at the solar radiation/convection zone boundary. Here we report measurements of wavelength-resolved iron opacity at electron temperatures of 1.9-2.3 million kelvin and electron densities of (0.7-4.0) × 10(22) per cubic centimetre, conditions very similar to those in the solar region that affects the discrepancy the most: the radiation/convection zone boundary. The measured wavelength-dependent opacity is 30-400 per cent higher than predicted. This represents roughly half the change in the mean opacity needed to resolve the solar discrepancy, even though iron is only one of many elements that contribute to opacity.

RESUMEN

We came across a 32 years old male admitted in our hospital with prolonged low-grade fever, haemoptysis, leg swelling, weight loss, purpuric rashes and malaena. He received anti-TB treatment at another hospital without any improvement. He was pale with bullous and purpuric lesions over legs and feet. He also had features of consolidation over both lung fields. His CRP was 312mg/L, Urine R/M/E showed 40-50 RBC/HPF, Chest X-ray showed features of bilateral consolidation, c-ANCA-10U/L (positive); Tracheal aspirate for AFB was found to be negative. We diagnosed the case as Granulomatosis with Polyangitis (WG) and started treatment with steroid and cyclophosphamide. But the patient could not be saved probably due to delay in starting management.

RESUMEN

Hypertension is a chronic and debilitating disease. Its complications give rise to cardiovascular diseases, stroke in Postmenopausal women. Estrogen deficiency that develops during menopause is likely the etiological factor for development of hypertension in postmenopausal women. Increased incidence of cardiovascular diseases in postmenopausal women may be due to hypertension caused by lower level of estrogen hormone. The study was carried out to observe the association of hypertension with serum estrogen level in postmenopausal women. This cross sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka, during the period of January 2011 to December 2011. A total number of 90 female subjects were selected from different areas of Dhaka city. Among them, 60 postmenopausal women with age ranging from 50 to 60 years were taken as study group and 30 apparently healthy premenopausal women with age ranging from 20 to 30 years were included as control group for comparison. Systolic blood pressure and diastolic blood pressure were recorded in both groups. Serum estrogen level was estimated in order to assess the hormonal level of both groups. Data was analyzed by Unpaired Student's 't' test and Pearson's co-efficient (r) test as applicable. The value of systolic blood pressure was higher in postmenopausal women than those of premenopausal women and result was statistically significant. The level of diastolic blood pressure was also significantly (p<0.001) higher in postmenopausal women in comparison to those of premenopausal women. In postmenopausal women serum estrogen level was lower than premenopausal women and serum estrogen level showed negative correlation with systolic and diastolic blood pressure levels. All these correlation were statistically non significant. Present study revealed that there is association of hypertension with serum estrogen level in postmenopausal women.

RESUMEN

Cervical cancer is the second most common cancer in women worldwide. Human papillomavirus (HPV) is considered as the main cause of invasive cervical cancer and cervical intra-epithelial neoplasia. High risk HPV DNA has been shown to be present in 99.7% of cervical cancers. So HPV DNA testing for screening of cervical cancers may play a potential role in early detection and management of cervical cancer. With above background a cross sectional study was undertaken to estimate the prevalence and to identify the associated risk factors of human Papillomavirus infection among Visual Inspection with Acetic acid (VIA) positive women attending at colposcopy clinic of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2013 to December 2014. One hundred and forty three cervical swabs for nested PCR were collected from the patients attending colposcopy clinic of MMCH, for detecting target gene of L1 region of the HPV genome. Among the 143 VIA positive patient nested PCR showed 49.6% (71/143) positive. Biopsy of 54 colposcopy positive women revealed that 16 (29.6%) cases were chronic cervicitis, 33 (61.1%) cases were mild dysplasia (C1NI), 01 (1.9%) were having moderate dysplasia (C1NII) and 04(7.4%) patients were diagnosed as invasive squamous cell carcinoma. So, high grade cervical lesions were 100% positive by nested PCR for HPV.

RESUMEN

This descriptive cross sectional study was done for the estimation of thyroid hormone in early pregnancy and it's clinical correlation. It was conducted at the Antenatal Clinic of Mymensingh Medical College Hospital, Mymensingh from December 2010 to November 2011. Total 185 cases in early pregnancy were taken purposively and randomly. Among the pregnant women, age ranged from 18-42 years with the Mean±SD age 25.77±4.96 years, the gestational weeks ranged 6±1 to 13±1weeks having Mean±SD 9.06± 2.49 weeks. The gravida ranged from primi to 8th gravida Mean±SD 1.89±1.10. Haemoglobin level ranged from 9.0 to 13.2gm/dl; Mean±SD 10.90±0.99gm/dl. Mean±SD of serum FT4 was 17.77±7.25 and Mean±SD of TSH was 3.95±2.94mIU/L. In present study, 5.40% (n=10) of the respondents had hypothyroidism and 0.54% (n=1) showed hyperthyroidism. The present study showed that, the incidence of hypothyroidism had relatively increased then the reference ranges but not statistically significant. But hyperthyroidism was within the reference range. This study showed slightly higher percentage of hypothyroidism in both ≤30 (4.52%) and ≥30 (10%) years of age groups especially a bit higher percentage in the elderly group. In present study, hypothyroidism was common among women of lower income group. Present study showed a higher percentage of stillbirth &miscarriage among study population. This study showed a relatively higher prevalence of abnormal thyroid function (especially hypothyroidism) in the study population and suggests the routine screening of thyroid hormone in early pregnancy in addition to routine antenatal care.

RESUMEN

This descriptive cross sectional study was conducted in Pediatric Out Patient Department (OPD) of Mymensingh Medical College Hospital (MMCH) from November 2013 to April 2014 to assess the knowledge and practices of the mothers about breastfeeding. Four hundred mothers having children 6 months to 2 years of age attended at OPD of MMCH for any cause were included in the study by systematic random sampling. A structured, pre-tested, interview schedule was used to collect data from mothers. All mothers were continuing to breastfeed their children. Two hundred and seventy-two (68.00%) infants received breast feeding within 1 hour after birth, while 128(32.00%) infants received breast feeding after 1 hour of birth. Of 128, in 48(37.50%) cases, mother's illness was the reason for delay in initiation of breast feeding, whereas in 70(54.69%) cases, it was due to reduced milk production on mother's statement. Pre-lacteal feeding was given in 96(24.00%) children. Among them honey was given in 24(25.00%) cases, cow's milk was given in 14(14.58%) cases, sugar water was given in 18(18.75%) cases and formula milk was given in 40(41.67%) cases. One hundred and twenty-eight (32.00%) mothers started to give their child food other than breast milk before 3 months of age and 148(37.00) mothers started to give their child food other than breast milk before 6 months of age. The reason for starting to give their child food other than breast milk before 6 months of age was mother's assumption of milk insufficiency in 166(60.14%) cases and baby's cry for hunger in 110(39.86%) cases. Formula milk was given in 120(30.00%) infants before 6 months of age. Among them 96(80.00%) mothers prepared it with larger amount of water. Plain water was given in 240(60.00%) children before the age of 6 months. One hundred and twenty-four (31.00%) children were exclusively breastfeed for first 6 months of age. Breastfeeding is almost universal in Bangladesh but the exclusive breastfeeding rate is alarmingly very low. Great emphasis is needed to educate mothers about benefits of colostrum, exclusive breastfeeding, and the harmful effects of pre-lacteal feeding.

RESUMEN

This descriptive cross sectional study was conducted in Pediatric out Patient Department (OPD) of Mymensingh Medical College Hospital (MMCH) from March 2014 to August 2014 to assess the knowledge and practices of the mothers in acute diarrhoeal diseases in children under-five years of age regarding use of oral rehydration solution (ORS), zinc, other drugs and feeding practices. Four hundred children under-five years of age having acute diarrhoea were included in the study by systematic random sampling. A structured, pretested, interviewer-administered questionnaire was used to collect data from mothers of children having diarrhoeal diseases. ORS was offered by 360(90.00%) of the mothers. Out of which 279(77.50%) used it by their own knowledge. One hundred and ninety-one (53.06%) mothers prepared it correctly, while 169(46.94%) prepared it incorrectly. Of 169, 129(35.83%) mothers used less amount of water, while 40(11.11%) mothers used much amount of water to prepare ORS. Of 360 mothers, 89(24.72%) mixed part of the content of ORS sachet at a time. Of 360 mothers, only 55(15.28%) offered correct amount of ORS after each purging. Zinc was offered in 142(35.50%) children. Of 400, only 13(3.25%) mothers used recommended home-based fluid, while 70(17.50%) mothers offered increased amount of fluid to their child. Drugs other than zinc and ORS were used in 247(61.75%) children. Among drugs, other than zinc and ORS, antibiotics was used in 109(44.13%) cases, whereas antiprotozoal in 97(39.27%) cases. Amount of liquid given was more than usual in 70(17.50%) children, same as usual in 57(14.25%) children and less than usual in 273(68.25%) children. Amount of food given was same as usual in 59(14.75%) children, while less than usual in 341(85.25%) children. Control of diarrhoeal diseases programme is successful in introducing ORS at mass level. Great emphasis is needed to educate mothers about preparation and quantity of ORS to be given to children with diarrhoeal diseases.

RESUMEN

Contrast material containing Iodine can cause parotitis. Here we present A 70 year's old man admitted to United Hospital Limited, Gulshan, Dhaka, Bangladesh on 5th May 2021 with the complaints of chest pain and shortness of breath and he was diagnosed as NSTEMI with ALVF. He was Covid 19 positive two weeks back. He underwent PCI to LM to LAD, LCX and RCA two years back. He had hypertension, diabetes mellitus and dyslipidemia. He was taking dual antiplatelet, beta-blocker, ACE inhibitor, statin, diuretic and anti-diabetic medication. His physical examination findings were reasonably normal. An electrocardiogram revealed bi-fascicular block and echocardiogram showed inferior wall and basal segment of inferior-lateral wall were hypokinetic. His high sensitive Troponin I was raised and serum creatinine was normal. This case report contains a case of bilateral parotitis following coronary angioplasty, subsided with conservative management. Possible reasons may be the direct toxicity or idiosyncratic reaction of the iodinated contrast agent.

RESUMEN

Hypertension is a common disorder of major clinical, public health and economic importance. It affects men and women of all ages, and the prevalence is increasing in most countries. Maintenance of blood pressure below 140/90 mm of Hg is recommended by most of the guideline available around the world. Various classes of drugs are being used in the treatment of hypertension. Losartan potassium and amlodipine are two different antihypertensive agents belonging to two different groups used commonly around the world in treating essential hypertension. Losartan potassium is non-peptide Angiotensin-II receptor antagonist. Amlodipine which is the third generation dihydropyridine group of calcium channel blocker. The aim of the study was to compare the efficacy and safety of amlodipine and losartan for the treatment of essential hypertensive patients (18-75 years). A non-randomized comparative observational study was conducted in the Department of Pharmacology and Therapeutics in collaboration with Department of Medicine, Sylhet, MAG Osmani Medical College, Sylhet, Bangladesh from July 2021 to June 2022. In this study non-randomization was in two groups. Group A received amlodipine 5mg daily at morning and Group B received losartan potassium 50mg daily at night. The study parameters were systolic blood pressure (SBP), diastolic blood pressure (DBP), ankle oedema, serum K+ level. The result of treatment outcome was compared between two groups. After treatment the reduction of SBP was 5.19±2.93mm of Hg versus 3.27±1.34mm of Hg (p<0.001); reduction of DBP was 1.7±0.70 mm of Hg versus 0.68 mm of Hg (p<0.001) and serum K+ level 4.22±0.27mmol/L versus 4.21±0.16mmol/L (p<0.719) in amlodipine and losartan group respectively. Amlodipine is more effective than losartan potassium in respect to treatment of essential hypertension. Regarding adverse events losartan potassium causes angioedema, hyperkalemia, headache, dizziness etc. The study concluded that amlodipine is superior to losartan potassium in treating essential hypertension.

RESUMEN

Evaluation of the in vitro antibacterial activity of Methanolic extracts isolated from Black pepper seeds (Piper nigrum L.) against two infection causing pathogens, Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. Between July 2022 and June 2023, this experimental study was conducted at the Mymensingh Medical College's Department of Pharmacology and Therapeutics in conjunction with the Department of Microbiology. Using the disc diffusion and broth dilution methods, the antibacterial activity of methanolic extract of black pepper seeds (MBPE) was evaluated at various doses. The solvents Methanol and 10.0% Di Methyl Sulfoxide (DMSO) were used to make the extract. Using the broth dilution procedure, the conventional antibiotic Ciprofloxacin was utilized and the outcome was contrasted with that of Methanol extracts. Methanolic extract of black pepper seeds (MBPE) at seven distinct concentrations (100, 80, 60, 40, 20, 10 and 5 mg/ml) were utilized, then later in chosen concentrations as needed to confirm the extracts' more precise margin of antimicrobial sensitivity. At 80 mg/ml and above doses of the MBPE, it had an inhibitory impact against the aforementioned microorganisms. For Staphylococcus aureus and Escherichia coli the MIC were 60 and 75 mg/ml in MBPE respectively. As of the MIC of Ciprofloxacin was 1µg/ml against Staphylococcus aureus and Escherichia coli. In comparison to MICs of MBPE for the test organisms, the MIC of Ciprofloxacin was the lowest. This study clearly shows that Staphylococcus aureus and Escherichia coli are sensitive to the methanolic extract of black pepper seeds' antibacterial properties.

RESUMEN

Chronic obstructive pulmonary disease (COPD) is a chronic obstructive disease of the airways. It is one of the most common and important chronic respiratory conditions in terms of years lived with disability. Incidence is increasing in Bangladesh like other developing countries. To evaluate drug prescription pattern for COPD, this cross-sectional, observational study was conducted from January to December in 2020 at the Department of Pharmacology in collaboration with the Department of Medicine in Mymensingh Medical College, Bangladesh. A total of 168 patients were selected for the study by non-random purposive sampling technique. Age distribution indicates that 31.5% of patients were in the 50-59 years age group and males were 93.5%. The majority (82.1%) of the participants were smokers. In this study, majority (34.12%) of the drugs were used as oral form and second most common dosage form was nebulization (26.75%). Bronchodilators were mostly prescribed 652(57.19%), followed by corticosteroids 222(19.47%) and antibiotics 165(14.47%) among drugs used for COPD. Beta sympathomimetics 322(45.49%) were mostly prescribed, followed by anticholinergics 186(28.52%) and methylxanthines 144(22.08%) as bronchodilators. Out of 1140 drugs for COPD, 53.06% and 34.12% were delivered as inhalation and oral forms, respectively. Inhalation route was the most (60.37%) preferred one over oral route (37.63%) for steroid use. The most of the patients [152 (90.48%)] were treated with combination therapy. Mostly (39.6%) used Fixed Dose Combination (FDC) therapy was salbutamol and ipratropium bromide followed by salmeteroal and Fluticasone (30.83%). Both FDC were prescribed in 57.7% of study population. Considering nomenclature, trade name was used in 24.4% of prescription.

RESUMEN

Evaluation of the in vitro antibacterial activity of Aqueous extracts isolated from Mint (Mentha piperita) leaf against two food born infection causing pathogens, gram-positive Staphylococcus aureus and gram-negative Escherichia coli. This interventional study was carried out in the Department of Pharmacology and Therapeutics in collaboration with the Department of Microbiology, Mymensingh Medical College, Bangladesh from January 2021 to December 2021. The antibacterial activity was tested at different concentrations of Aqueous Mint leaf extracts by using disc diffusion & broth dilution method. The extract was prepared by using solvents Aqueous. The test microorganisms were also tested for their activity against a standard antibiotic Gentamicin by broth dilution method and the result was compared with that of Aqueous extracts. Aqueous extract of Mint leaves (AMLE) were used initially in eight different concentrations (25, 50, 100, 200, 400, 600, 800 and 1000µg/ml) and later in selected concentrations as needed to confirm the more precise margin of antimicrobial sensitivity of the extracts. Among different concentrations of the AMLE, 200µg/ml and above concentrations showed inhibitory effect against Staphylococcus aureus and 400µg/ml and above concentrations showed inhibitory effect against Escherichia coli. Minimum inhibitory concentration (MIC) for Staphylococcus aureus and Escherichia coli were 200 and 400µg/ml in AMLE respectively. The MIC of Gentamicin was 1µg/ml against Staphylococcus aureus and 1.5µg/ml against Escherichia coli. The MIC of Gentamicin was the lowest in comparison to MICs of AMLE for the test organisms. This study showed that Aqueous Mint extracts demonstrated antibacterial effects against food borne pathogens. It is clearly observed that there is definite antibacterial effect of the aqueous extract of Mint leaves against Staphylococcus aureus and Escherichia coli.

RESUMEN

Mechanical prosthetic valve thrombosis is a serious complication which necessitates immediate intervention. The presenting signs and symptoms of this illness are somewhat variable, but physical examination and trans-esophageal-echocardiography enable rapid diagnosis. Valve replacement or thrombolysis in the correct hospital setting must be performed to avoid life-threatening complication without delay. But it is not proven entirely which therapy is superior. For any given patient, the risks of thrombolytic therapy, including bleeding, systemic embolism and failure to restore valvular function, must be weighed against the risks of surgical intervention. In spite of aggressive therapy, morbidity and mortality from prosthetic valve thrombosis and its treatment are not less indeed. This report describes the case of a woman with aortic prosthetic valves who presents with heart failure and evidence of severe prosthetic aortic valve dysfunction after a period of suboptimal anticoagulation.

RESUMEN

Increasing resistance of pathogenic microorganisms to synthetic antibiotics has lead to the search for alternative drug sources. In this regard, one of the reputed Medicinal plant, Moringa (Moringa oleifera) was investigated for potential antimicrobial effect against some commonly encountered bacteria such as Staphylococcus aureus, Escherichia coli. This experimental study was conducted from July 2019 to June 2020 in the Department of Pharmacology and Therapeutics in collaboration with the Department of Microbiology, Mymensingh Medical College, Bangladesh to determine the antibacterial effect of Ethanolic extract of Moringa oleifera leaf (EMLE) against aforementioned bacteria. The antibacterial activity was tested at different concentrations (100, 200, 400, 600, 800 and 1000µg/ml) of Ethanolic extract by using disc diffusion and broth dilution method. Dose dependent inhibitory effect was seen against the test organisms using disc diffusion method. The maximum zone of inhibition was 19 mm against S. aureus and 20mm against E. coli at 100.0% (1000µg/ml) concentration. The minimum inhibitory concentrations (MICs) of EMLE were 400µg/ml and 500µg/ml against Staphylococcus aureus and Escherichia coli respectively. The present study showed that Ethanolic extract of Moringa leaf demonstrated antibacterial effects against food borne pathogens. Further studies are required to detect and isolate the active ingredients present in the Moringa leaves extract responsible for its antibacterial effect.

RESUMEN

Rickettsial diseases are one of the leading causes of treatable acute febrile illness in Asia pacific region. This cross-sectional descriptive study was conducted at Department of Microbiology, Mymensingh Medical College to diagnose scrub typhus by rapid Immunochromatographic Test (ICT) and Nested PCR followed by molecular identification of possible Rickettsial coinfection among suspected febrile patients in Mymensingh, Bangladesh from March 2019 to February 2020. Among the enrolled 402 patients, 89 samples (22.13%) were seropositive by Immunochromatographic Test (ICT) and 65 samples (16.16%) were positive for O. tsutsugamushi DNA by Nested PCR, targeting 47KDa gene. Therefore, 113/402 (28.10%) samples were positive for scrub typhus by PCR and/or ICT. All the scrub typhus positive samples were further subjected to Nested PCR targeting 17 KDa gene for identification of Rickettsial co-infection and 13/113 (11.50%) were documented as positive. Then 13 Rickettsial co-infected samples were undertaken to automate sequencing and all were genetically confirmed as Rickettsia felis. Findings of the study may help clinicians to expand their list of differential diagnoses for undifferentiated fever and detection of Rickettsial co-infection may guide them to prescribe effective antimicrobials.

RESUMEN

Female breast cancer can be diagnosed easily; but due to inappropriate health care utilization, health-seeking is lag behind. The objectives of the study were to find out the pattern of utilization of health care during breast cancer diagnosis and treatment and their health seeking time. We conducted this cross sectional study for one year; from July 2017 to June 2018 among 200 newly diagnose patients with breast cancer whose were selected randomly from National Institute of Cancer Research and Hospital, Dhaka, Bangladesh from the listed patients who attended at the outpatient department of chemotherapy day care center for treatment. Delay in reporting, wrong reporting, double reporting, delay in hospital admission, long queue for administrative work and delay to reach cancer specialist play a role in utilization of health care. Results showed that health care service delivery and utilization was found to be significant by (p<0.05) associated with the provider delay (p=0.010), total delay (p=0.017), delay to consult with cancer specialist (p<0.0001). By logistic regression it analyzed that utilization of health care there had 2 times more likely to cause provider delay (OR=2.5; 95% CI 1.087-5.762) p=0.03. Utilization of health care influenced stage of cancer with delay help seeking and diagnostic institution also. As low middle income country, like Bangladesh, delays in seeking consultation, late presentation and the availability of breast cancer management for all patients, represent major challenges.

RESUMEN

Rheumatic heart disease causes a substantial number of morbidity and mortality in Southeast Asia. In Bangladesh prevalence of Rheumatic Fever and Rheumatic heart disease is still high, 0.6 and 0.3 per thousand populations, respectively. Mitral valve mostly involved in the form of mitral stenosis in the rheumatic process. Treatment selections and its success largely depend upon the severity of disease especially the extent and distribution of calcification. Echocardiography has got the key role in determining the pattern, extent and severity of mitral stenosis. Two dimensional and Doppler echocardiography are conventionally used. With the increasing availability of 3D echocardiography, better cardiac imaging is possible now. The heart being a complex three-dimensional structure, the 3D evaluation would definitely offer better imaging for accurate assessment of the severity of mitral stenosis, especially details of commissural involvements. Many scoring systems are available for the assessment of the severity of rheumatic Mintral Stenosis (MS), mostly 2DE based; among them, Wilkins is mostly practiced. This cross-sectional observational study was conducted in University Cardiac Centre, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from May 2012 to October 2012. Data were collected from 50 subjects who underwent transthoracic 2D and 3D Echocardiography for the assessment of rheumatic mitral stenosis especially detection of calcification also it's severity, extent, and distribution, furthermore the presence of commissural calcification. Precise measurement of Mitral valvular area is essential in the assessment of severity, which is found similar by both 2DE (0.98±0.24cm²) and 3DE (0.92±0.23cm²). But in identifying calcification and its extent especially commissural involvement is better detected by 3DE (p=0.002). This has paramount importance in therapeutic decision making of chronic rheumatic MS. To make a well-organized management plan and also for the confident prediction of complications, three-dimensional echocardiography has promising prospects in detecting commissural calcification and should be considered as an essential adjuvant to the conventional two-dimensional echocardiography.

RESUMEN

Rheumatic heart disease causes a substantial number of morbidity and mortality in South Asia. With the increasing urbanization & antibiotic availability, it is now in declining trends. The prevalence of Rheumatic Fever and Chronic Rheumatic Heart Disease in Bangladesh is 0.6 and 0.3 per thousand populations, respectively. Mitral valve is mostly involved in the rheumatic process, particularly in the form of mitral stenosis. Treatment options of mitral stenosis depend upon the severity of the disease. Echocardiography has a key role in determining the pattern, extent and severity of the involvement of the mitral valve apparatus. 2D and Doppler echocardiography are conventionally used. 3D echocardiography is more available nowadays. The heart being a complex three-dimensional structure, a 3D evaluation would definitely offer better visualization for accurate assessment of the severity of rheumatic mitral stenosis. There are many echocardiography based scoring systems are available for the assessment of the severity of rheumatic MS. Those are mostly 2DE based; among them, Wilkins is widely practiced. Real-time 3DE based score for mitral stenosis is developed recently. This cross-sectional observational study was done in the University Cardiac Centre, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from May 2012 to October 2012. Considering all ethical issues, data were collected from 50 subjects who underwent transthoracic 2D and 3D Echocardiography for the assessment of the extent and severity of mitral stenosis. Precise measurement of the mitral valvular area is of a pivotal role in the assessment of severity, which is found almost similar by both 2DE (0.98±0.24cm²) and 3DE (0.92±0.23cm²). But in identifying calcification and its extent specifically commissural involvement is better detected by 3DE (p=0.002). Detail assessment of subvalvular involvement particularly chordal adhesion can better be done by 3DE (p<0.001). All of these have important contributions in formulating the most favorable therapeutic roadmap in chronic rheumatic MS. To make an efficient management plan and also for the confident prediction of complications, three-dimensional echocardiography has promising prospects and should be considered as an important adjuvant to the conventional two-dimensional echocardiography.

RESUMEN

The patient with diabetes mellitus and its complication is increasing in our country and all over the world. Altered platelet morphology and function have been reported in patient with DM. Mean platelet volume has been suggested as a newly emerging and independent risk marker for atherothrombosis and cardiovascular disease. The present study was carried out to assess the mean platelet volume in subjects with type 2 diabetes mellitus. The present study was a cross sectional analytic study and conducted in the Department of Physiology, Dhaka Medical College, Dhaka, Bangladesh from July 2013 to June 2014. A total number of 200 adult male subjects were selected with age ranging from 40 to 60 years. Among them, 100 subjects with type 2 diabetes mellitus were included in the case (Group B) and 100 healthy subjects with same age range were considered as control (Group A) for comparison. The subjects were selected from BIRDEM hospital Dhaka and personal contact from different areas of Dhaka city on the basis of exclusion and inclusion criteria. The study parameter was mean platelet volume and was measured in the Department of Hematology of BIRDEM hospital, Dhaka. The data were collected and recorded in pre-designed structured questionnaire by the researcher herself. For statistical analyses unpaired Student's 't' test was performed as applicable using SPSS for windows version 19. In this study, mean platelet volume was significantly (p<0.001) higher in the case group than that of control group. Therefore, estimation of mean platelet volume might be beneficial for prediction of future cardiovascular risk in adult diabetic male.

RESUMEN

Unsafe abortion is one of the most critical global public health concerns and human rights challenges of the current time. The complications arising from unsafe abortion account for the death of almost 192 women each day; that is one woman every eight minutes and nearly all of them in developing countries. It is a descriptive type of observational study where all abortion related admissions from July 2017 to June 2018 in Obstetrics & Gynaecology department of Mymensingh Medical College Hospital were analyzed. Cases of unsafe abortion were identified as missed abortion, incomplete abortion and septic abortion. Total 2396 abortion related cases were admitted in one year. Among them 2173 cases were unsafe abortion (90.69%). The commonest mode of unsafe abortion was by taking improper regimen of different types of oral abortifacients either by self-administration or by improper prescriptions of local medical dispensers in 90% women. The commonest clinical presentation was per vaginal moderate to heavy bleeding in 88.5% women. After evaluation, the commonest diagnosis made was incomplete abortion in 92.87% women. The first line of intervention taken was recommended dose of medications like Misoprostol alone or Misoprostol followed by Mifepristone in 96.3% women to avoid unnecessary endometrial injury by surgical procedure. Further 44.2% women underwent Manual Vacuum Aspiration and thus reducing hospital stay to around 3.0±0.25 days. Almost all the patients (94%) were given post abortion contraceptives along with long acting family planning services to 20% patients. The miserable complication was septic abortion in 1.29% women and they were mainly done by insertion of foreign bodies which contribute to total 4.4% of maternal death. The impact of unsafe abortion on the woman and her family is intimidating. Timely and proper management of unsafe abortions and their complications with adequate provision for post abortion care may reduce the morbidity and mortality related to it. Moreover, use of long acting contraceptives to prevent unintended pregnancy and access to safe abortion may reduce the burden of unsafe abortions on public health system.
