Comparison of Outcome of Eclamptic Patient Following Vaginal Delivery versus Caeserian Delivery by Spinal Anaesthesia

Eclampsia is a common problem in pregnancy in Bangladesh. It is a severe form of preeclampsia which affects 5 to 7% of pregnancies is a significant cause of maternal & neonatal morbidity & mortality. Pre-eclampsia when complicated with generalized tonic-clonic convulsions and/or coma is called eclampsia. The term eclampsia is derived from a Greek word, meaning "like a flash of lightening". It may occur quite abruptly, without any warning manifestations. Eclampsia is a major cause of maternal mortality & morbidity as well as foetal loss worldwide, particularly in the third world. Appropriate measures & effective treatment of eclamptic patient in proper time reduce maternal mortality & morbidity. The mainstay of treatment of eclampsia is delivery of the foetus. Two methods are usually applied for delivery of foetus in eclampsia i.e. vaginal delivery & caesarean delivery. This study was done in the department of Gynae & Obs and department of Anaesthesiology, Mymensingh Medical College Hospital from 1st January 2016 to 30th June 2016 to observe the incidence, complications (morbidity) & mortality of eclamptic patients & which method (vaginal delivery versus caesarean delivery by spinal anaesthesia) is safe, better for the eclamptic patients as well as foetal mortality. Successful vaginal delivery is dependant on complex interactions of three variables (3 P) that is power (uterine contraction), passenger (foetus) & passage (birth canal) but power is less effective in eclamptic patient than normal partuents. Vaginal delivery requires prolong times compared with cesarean delivery. Anaesthetic technique is also an important factor for maternal mortality & morbidity of caesarean delivery. Spinal anaesthesia is widely regarded as a reasonable anaesthetic option for caesarean delivery in eclamptic patients. Currently the safety of spinal anaesthesia is well established and it can provide better obstetrical outcome when chosen properly. In this observation caesarean delivery by spinal anesthesia is safer, less complications, less maternal & neonatal mortality than vaginal delivery in eclamptic patients.

Surgical Management of a Critical Ischemic Mitral Regurgitation Patient

Functional ischemic mitral regurgitation is strongly associated with poor outcomes in patient with coronary artery disease. The best management for mitral regurgitation at the time of coronary revascularization remains controversial. We report, a case of 58 years-old men admitted to GKNM hospital, Coimbatore, Tamil Nadu, India with chest pain and respiratory distress for last 6 hours during my fellowship training in that hospital. ECG showed acute antero-septal MI. The transthoracic echocardiogram revealed severe left ventricular dysfunction with moderate mitral regurgitation. Coronary angiogram revealed triple vessels disease. We planned for early CABG. But the patient suddenly developed severe respiratory distress with ventricular tachycardia. Patient managed with the support of invasive ventilation and IABP. After that, CABG along with mitral valve repair was done under cardiopulmonary bypass. The patient showed excellent symptomatic improvement during his early post-operative period. Mitral valve repair along with CABG may be a preferable treatment option for patient with Ischemic heart disease with moderate mitral regurgitation.

Heavy metal accumulation in leafy vegetables grown in industrial areas under varying levels of pollution

The concentration of lead (Pb), cadmium (Cd), nickel (Ni), cobalt (Co) and chromium (Cr) in three popular leafy vegetables such as spinach (Spinacia oleracea), red amaranth (Amaranthus tricolor) and amaranth (Amaranthus oleraseus) and that in the respective soils were assessed. These crops and soils were collected from two industrial areas (Kalakoir and Zorun, Konabari, Gazipur), and one non-industrial area (Bangladesh Agricultural Research Institute-BARI) under Gazipur district. The concentration of heavy metal in different parts of plant followed the roots>leaves>stem and in soils the order was Kalakoir (pollution)> Zorun (medium pollution) > BARI (low/non-pollution). In all three leafy vegetables similar trend of metal contents was observed i.e. Ni>Cr>Pb>Co>Cd. In the highly pollution area (Kalakoir) the Pb and Ni concentration was found in the order of amaranth>spinach>red amaranth. The Cd concentration was in the order of spinach>amaranth>red amaranth whereas for Cd it was amaranth>red amaranth>spinach and for Cr it was red amaranth>amaranth>spinach. The Pb, Cd, Ni, Co and Cr concentrations in the studied vegetables grown in the low polluted area were below the maximum acceptable levels proposed by the Joint FAO/WHO Expert Committee on Food Additives, except, Cd in spinach and amaranth. However, the higher concentrations of Pb, Cd, Ni, Co and Cr in vegetables grown in the industrial areas indicates that industrial discharge causes heavy metals contamination of soil and eventually their accumulation in plants.Bangladesh J. Agril. Res. 43(1): 39-51, March 2018

Immediate Outcome of Preterm Neonates with Respiratory Distress Syndrome Required Mechanical Ventilation

Since its inception, the neonatal mechanical ventilator has been considered an essential tool for managing preterm neonates with Respiratory Distress Syndrome (RDS) and is still regarded as an integral component in the neonatal respiratory care continuum. Mechanical ventilation of newborn has been practiced for several years with several advances made in the way. This clinical intervention study was done to analyze immediate outcome of preterm neonates with RDS required mechanical ventilation and conducted on preterm neonates with RDS required mechanical ventilation from July 2014 to June 2015. Total of 31 preterm neonates with RDS were mechanically ventilated during the study period, of which 77.42% (N=24) survived. The survival rate was highest among 30- <34 weeks (100%) gestational age (GA) group and lowest in 27- <30 weeks (56%) GA, (p=0.0036). The neonates with Birth Weight (BW) 1500gm -1800gm were higher rate of recovery which was 100% and gradually declined in 1000-1499gm (93.75%) and 800-999gm (33.33%) BW groups (p=0.00083). In this study most of the neonates were male (61.29%) but recovery rate was relatively better among baby girls (83.33%) than baby boys (73.68%) (p=0.53). RDS with surfactant therapy was better outcome than non surfactant group & survival of neonates who got surfactant were 93.33% & non surfactant neonates were 62.50%, (p=0.040). Majority (71.43%) of RDS with surfactant therapy recovered earlier <7 days than non surfactant therapy neonates (30.00%) and most of non surfactant neonates (70.00%) required prolonged ventilator support >7days (p=0.045). During the period of ventilation a total 17(54.84%) neonates developed different complications, of which ventilator associated pneumonia was (16.13%), sepsis (16.13%), pneumothorax (9.68%), pulmonary hemorrhage (6.45%) and intraventricular hemorrhage (6.45%) and among them 10 neonates recovered. No complications encountered in 14(45.16%) neonates, all of them survived, (p=0.0064). All (N=31) preterm neonates were candidate for surfactant therapy but only 15 neonates got surfactant therapy, remaining (N=16) did not get for their financial issue. As mechanical ventilation with surfactant therapy reduces the neonatal mortality; hence, facilities for neonatal ventilation and cost effective surfactant therapy should be included in the regional and central hospitals providing intensive care for neonates.

Distribution Pattern and Outcome of the Patients in the Intensive Care Unit of Bangabandhu Sheikh Mujib Medical University: A Short Term Analysis

The aim of the study was to describe the characteristics of patients admitted to intensive care unit and their outcome in Bangabandhu Sheikh Mujib Medical University, Bangladesh. This retrospective, descriptive study was conducted in the intensive care unit of Bangabandhu Sheikh Mujib Medical University (BSMMU) from January 2016 to June 2016. Data was retrieved from hospital records of all admitted patients regarding age, gender, admission source, reason for admission, length of ICU stay, requirement of mechanical ventilation, number of organ failure and their outcome. During this study period, the total number of patients admitted was 225; most of them were males (148, 65.7%). Among the 225 patients, the highest number of admission was comprised of intracranial haemorrhage (22.6%), followed by sepsis (12.4%), acute respiratory distress syndrome (10.2%), acute renal failure (9.3%) malignancy (8.8%) and ischemic stroke (8.0%). Mean age of the patient was 54±18 years and mean length of ICU stay was 6.8±3 days. Out of 225 patients, 87 expired (38.6%). Majority of the patients required mechanical ventilation (69.3%) and had multi organ failure (59.8%). Most of the expiries were due to intracranial haemorrhage (24.1%); followed by acute respiratory distress syndrome (12.6%), malignancy (12.6%) and sepsis (11.4%). Elderly age (>65 years), requirement of mechanical ventilation and multiorgan failure had significant relationship (p<0.05) with overall ICU mortality. Intracranial haemorrhage, sepsis, acute respiratory distress syndrome were the main reasons for admissions in ICU, while mortality was highest for intracranial haemorrhage. Developing a well equipped neurological ICU with adequately trained staff will help to improve the outcome of patients.

Evaluation of Intraoral Burning Sensation in Response to Heat-Cured and Self-Cured Acrylic Resin Denture Base Material

The objective of this prospective experimental clinical trial was to evaluate intraoral burning sensation in response to heat-cured and self-cured acrylic resin denture base material and carried out in the department of Prosthodontics of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from February 2014 to September 2015. Forty eight patients were evaluated in this study; of them 35(72.92%) patients were male and 13(27.08%) patients were female with age range from 24 to 70 years. In this study 48 patients were evaluated in term of burning sensation, of them 24 patients were provided with heat-cured acrylic resin denture and were considered as Group A and 24 patients were provided with self-cured acrylic resin denture and were considered as Group B. In Group A 14(58.4%) at 1st week, 2(8.4%) at 1st month, 10(41.8%) at 3rd month and 5(21.0%) at 6th month developed burning sensation. On the other hand the values were 18(75.0%), 22(91.6%), 14(58.2%) and 2(8.4%) at 1stweek, 1st month, 3rd month, and 6th month respectively. Chi-square test was done for statistical analysis and p value was <0.05. So, results were statistically significant.

Risk Factors and Immediate Neonatal Outcome of Multiple Pregnancies in a SCANU of A Tertiary Care Hospital, Bangladesh

Multiple pregnancies are a significant risk factor for maternal and perinatal morbidity due to inherent biological risks. The present study was aimed to determine the risk factors and to evaluate the immediate neonatal outcome of multiple pregnancies. This descriptive observational study was conducted in the newly established Special Care Neonatal Unit (SCANU) of Mymensingh Medical College Hospital (MMCH), Bangladesh from January 2015 to March 2015. Total 86 newborns of multiple pregnancies who were admitted during the study period were included in the study. Among them 34 pairs were twin, and 6 sets of triplets were present. Among all infants in the study 79.1% were twin and 20.9% were triplet. According to our observation most of the mother aged between 20-29 years (67.5%) and majorities of them were multi-para (62.5%). Preterm delivery occurred in 70.0% cases. 75% newborns were delivered by caesarian section and remaining by vaginal route. The most common risk factors in present study are use of ovulation induction drugs (52.5%) for sub fertility followed by family history of multiple gestations. In 35.0% cases we did not find any cause. Common morbidities of the infants were preterm low birth weight (95.3%), neonatal jaundice (81.3%), RDS (34.8%), perinatal asphyxia (PNA) (17.4%), neonatal sepsis (25.0%) and congenital anomalies (23.2%). Mortality rate of twin was 30% and for triplets it was 50%. Among total study population mortality rate was 30.2%. Main causes of mortality was preterm low birth weight (76%), RDS (57.6%), septicaemia (26%), PNA (19.0%). Morbidities and mortalities in infants of multiple pregnancies are observed much higher than singleton pregnancy. We hope that in light of our findings regarding risk factors like assisted reproduction and their consequences over mother and newborn, periodic reviews will be done in future to reduce the incidence and the unfavourable outcome of multiple pregnancy.

Prevalence of Metallo-β-lactamase Producing Non-fermentative Pseudomonas Species from Clinical Isolates in Dhaka, Bangladesh

Antimicrobial drug resistance, a global concern, has been increasing unpredictably in microorganism causing human infections specially among Gram negative non-fermenting Pseudomonas spp. Carbapenems, a beta lactam antibiotics, are the most potent and effective drug usually kept reserved for treating the multi-drug resistant Psedomonas spp and other infections caused by organisms producing Extended Spectrum Beta Lactamase (ESBL) and AmpC. Clinical utility of carbapenem will reduce when resistant bacteria evolve due to production of carbapenem hydrolyzing Metallo-β-lactamase (MBL) which confers high-level resistance to all beta-lactam antibiotics except aztreonam. The various reports on the prevalence of MBLs are available from many countries but few from Bangladesh. We investigated the prevalence of MBL production in these Pseudomonads obtained from clinical sources in an uraban setting in Dhaka, Bangladesh. A total of 29,136 specimens were processed for culture from January 2011 and December 2015 from non duplicated patients attending diagnostic unit of icddr,b from different settings of Bangladesh. The specimens included urine 14,323; blood 11,378; other body fluid 2,487; sputum 535 and tracheal aspirate 413. All specimens were processed for culture following standard bacteriological methods and the Pseudomonas spp were identified following defined standard biochemical procedures. Metallo-β-lactamase (MBL) was determined by EDTA disk synergy (EDS) test. Antimicrobial susceptibility test was performed by disk diffusion method and susceptibility pattern was interpreted and reported following Clinical Laboratory Standard Institute (CLSI) guideline. From 29,136 specimens a total of 2,340(8%) were isolated and identified as Pseudomonas spp. Of the identified Pseudomonas spp, 238(57.6%) were from tracheal aspirate, 216(40.4%) from sputum, 902(36.7%) from other body fluids, 463(4.1%) from blood and 521(3.6%) from urine samples. From 2,340 Pseudomonas spp, by selective sampling, imipenem-meropenem resistant and intermediate susceptible 100 strains were tested for MBL production and 92 were found positive. Tracheal aspirate showed 38%, other body fluids 30%, Urine 17%, sputum 4% and blood 3% MBL production respectively. Irrespective of the sources of specimens, Pseudomonas spp showed 71% resistance to cefixime, 70% to ceftriaxone, 64% to gentamicin, 56% to piperecillin+tazobactam, 50% to ciprofloxacin, 49% to amikacin, 46% to netilmicin, 45% to ceftazidime, 30% to meropenem, 26% to imipenem and 19% to polymyxin B. As multi-drug resistant Pseudomonas showed high level of (92%) MBL production, so MBL detection testing facility may be a useful battery to determine MDR producing Pseudomonas from clinical isolates.

Identification and molecular characterization of Echinococcus granulosus from domestic goat in Chittagong, Bangladesh

The tapeworm Echinococcus granulosus causes cystic echinococcosis (CE) in human and many domestic animals worldwide including Bangladesh. The parasite has significant public health importance in the country and no in-depth study has been conducted to determine this cestode in either human or animals. The aim of present study was to evaluate genotype of E. granulosus isolated from domestic goats reared in Chittagong, Bangladesh using DNA based tools. Partial gene fragment of 12S rRNA gene and Cytochrome oxidase 1 gene were accomplished by PCR followed by sequencing and phylogenetic analyses. A total of 19 hydatid cyst samples were collected from 385 goats from several local slaughterhouses located in Chittagong. The rates of fertile hydatid cysts were found as high as 57.89% while remaining cysts were found non-viable and sterile. Genomic DNA was extracted from germinal membrane and/or protoscolices for PCR assay. Sequence similarity based on BLAST search revealed variable prevalence of E. granulosus genotypes such as G1 (68.42%) and G1/G3 complex (31.58%) which is reported for the first time in the country. This result indicates common sheep strain G1 is the dominant subtype of E. granulosus in this region. The study generated six sequences of which four were aligned with G1 common sheep strain and two were aligned with G3 strain (commonly referred as Buffalo strain). Phylogenetic analysis of 12S rRNA gene and Cytochrome oxidase 1 gene also indicated that common sheep strain (G1) and Buffalo strain (G3) are circulating among domestic goats in Chittagong region of Bangladesh.

Comparative yielding of BACTEC MGIT 960 and GeneXpert MTB/RIF Assay for Rapid Diagnosis of Drug Resistance Tuberculosis from Sputum Specimen

Among communicable disease, tuberculosis is the second leading cause of death worldwide, killing nearly two million people each year. Several diagnostic techniques are currently used to detect mycobacteria in respiratory specimens. Therefore an alternative, rapid and most effective method is required for diagnosis of pulmonary tuberculosis which is relatively more sensitive and specific. A total of 107 sputum samples of suspected TB patients were enrolled attending the National Tuberculosis Reference Laboratory (NTRL), Mohakhali, Dhaka, Bangladesh from July 2014 to July 2015. Liquid culture of 107 sputum samples, yielded 76.63% culture positive and 1.86% contamination was observed. Antibiotic susceptibility test was done for 82 culture positive sputum samples among which 28.04% cases were resistant to both Rifampicin and Isoniazid. GeneXpert assay detected 85.04% M. tuberculosis among which 25.23% were found to be Rifampicin Resistance.

OncoE6 Positivity among VIA Positive Suspected Cases from Colposcopy Clinic of Mymensingh Medical College Hospital, Mymensingh

Cervical cancer is a major world health problem for women. It is the fourth most leading cause of death in women around the world. High risk HPV DNA has been shown to be present in 99.7% of cervical cancers worldwide. Oncoprotein E6 and E7 play an important role in the development of cervical cancer which can be detected by OncoE6 cervical test. This Cross sectional observational study was performed to detect E6 Oncoprotein from cervical swab by OncoE6 cervical test. Following universal safety precautions a total of 47 endocervical swabs were collected from Colposcopy clinic of Obstetrics and Gynaecology department of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from January 2015 to December 2015. Laboratory work was done in the department of Microbiology, Mymensingh medical college. E6 strip test is an immunochromatographic test based on the detection of HPV-E6 oncoprotein in cervical swab samples. The swab specimen was treated with lysis solution and conditioning solution. Then the specimen solution was clarified by centrifugation. After that the sample solution was transferred into Detector mAb vial, wash solution vial and finally into developing solution vial. The test unit was then placed on a reading guide. Positive result was indicated by the appearance of purple colored test line. Out of 47 specimens 21(44.68%) were OncoE6 positive by OncoE6 cervical test. Among 21 positive cases 19(90.48%) were HPV-16 and 2 were (9.52%) HPV-18. Histopathologically out of 22 cervical carcinoma cases 20(90.90%) were positive by this test. Based on the findings of the present study, it may be concluded that screening with HPV E6 may minimize the overtreatment as well as the colposcopy referral. So it can be used as primary screening to aid colposcopy and to identify real disease. HPV based screening may help to control cervical cancer in Bangladesh. As HPV is a sexually transmitted infection; so, male screening method should be established.

Inhibition of human cytochromes P450 in vitro by ritonavir and cobicistat

OBJECTIVES

Ritonavir and cobicistat are strong inhibitors of human cytochrome P450-3A (CYP3A) isoforms, and are used clinically as pharmacokinetic boosting agents for other antiretroviral drugs. Data reported by the manufacturer suggest that cobicistat is a more selective inhibitor of CYP3A than ritonavir. However, this claim has not been validated in clinical studies. This study evaluated the in-vitro inhibitory potency of ritonavir and cobicistat vs a series of human CYP isoforms.

METHOD

The model system utilized human liver microsomes and isoform-selective index substrates.

KEY FINDINGS

Ritonavir and cobicistat both were strong inhibitors of CYP3A4, with IC₅₀ values of 0.014 and 0.032 μm, respectively. A component of inhibition was time-dependent (mechanism-based). Neither drug meaningfully inhibited CYP1A2 (IC₅₀  > 150 μm). CYP2B6, CYP2C9, CYP2C19 and CYP2D6 were inhibited by both drugs, but with IC₅₀ values exceeding 6 μm.

CONCLUSIONS

Consistent with previous reports, both ritonavir and cobicistat were highly potent inhibitors of CYP3A. Both drugs were weaker inhibitors of other human CYPs, with IC₅₀ values at least two orders of magnitude higher. There was no evidence of a meaningful difference in selectivity between the two drugs.

In vitro inhibition of human UGT isoforms by ritonavir and cobicistat

1. Ritonavir and cobicistat are pharmacokinetic boosting agents used to increase systemic exposure to other antiretroviral therapies. The manufacturer's data suggests that cobicistat is a more selective CYP3A4 inhibitor than ritonavir. However, the inhibitory effect of ritonavir and cobicistat on human UDP glucuronosyltransferase (UGT) enzymes in Phase II metabolism is not established. This study evaluated the inhibition of human UGT isoforms by ritonavir versus cobicistat. 2. Acetaminophen and ibuprofen were used as substrates to evaluate the metabolic activity of the principal human UGTs. Metabolite formation rates were determined by HPLC analysis of incubates following in vitro incubation of index substrates with human liver microsomes (HLMs) at different concentrations of ritonavir or cobicistat. Probenecid and estradiol served as positive control inhibitors. 3. The 50% inhibitory concentrations (IC₅₀) of cobicistat and ritonavir were at least 50 µM, which substantially exceeds usual clinical plasma concentrations. Probenecid inhibited the glucuronidation of acetaminophen (IC₅₀ 0.7 mM), but not glucuronidation of ibuprofen. At relatively high concentrations, estradiol inhibited ibuprofen glucuronidation (IC₅₀ 17 µM). 4. Ritonavir and cobicistat are unlikely to produce clinically important drug interactions involving drugs metabolized to glucuronide conjugates by UGT1A1, 1A3, 1A6, 1A9, 2B4 and 2B7.

Nationwide prevalence of Rickettsia felis infections in patients with febrile illness in Bangladesh

From July 2015 to December 2016, the presence of rickettsial pathogens was investigated for 414 patients with unknown fever in eight places in all the divisions of Bangladesh. Rickettsia felis was identified in blood samples from all the regions (overall detection rate, 19.6%), suggesting nationwide prevalence of R. felis infections.

Risk Factors and Immediate Outcome of Very Low Birth Weight Babies (Appropriate For Gestational Age) In Newly Established SCANU, Mymensingh Medical College Hospital

Low birth weight (LBW) is the most important preventable cause in the neonatal period leading to very high neonatal mortality and morbidity in developing countries like Bangladesh. A cross sectional study was conducted in the neonatology ward, Mymensingh Medical College Hospital, Mymensingh from July 2014 to December 2014 to identify the risk factors and immediate hospital outcome of Very Low Birth Weight (VLBW) Appropriate for Gestational Age (AGA) babies in context of present neonatal hospital care standard. Total 100 preterm very low birth weight babies were enrolled and selected by weight, intra uterine growth chart and new ballad score. There is slight preponderance of male babies (64%) over female babies (36%). The overall survival and mortality rate was 50% and 50% respectively in the present study. Mortality is highest (76.47%) in babies whose gestational age 28 weeks and the mortality rate gradually decrease as gestational age increases. Correlation co-efficient (r) between gestational age and number of died is -0.85. It indicates highly opposite relation between the variables, p value (<0.069) which is strong opposite relation. Mortality is highest (66.66%) in babies whose birth weight below1100gm, in comparison to those whose birth weight above 1100gm and correlation co-efficient (CC) r = -0.433 (p<0.466) which is not significant. That means not only birth weight but also other factors are responsible for mortality of very low birth weight baby. Neonatal mortality bears inverse relationship with birth weight and gestational age. This emphasized the need for large scale study which will provide the guideline for appropriate measures to be taken to combat the situation.

Deep Vein Thrombosis in A Post-Coronary Artery Bypass Grafting Patient: Successful Conservative Management

Deep vein thrombosis is an alarming medical emergency. Deep vein thrombosis or deep venous thrombosis (DVT) is the formation of a blood clot (thrombus) within a deep vein predominantly in the legs. Post-Coronary Artery Bypass Grafting deep vein thrombosis is a very rare medical condition relatively in Asian. Approximately 80% of deep vein thrombosis (DVTs) is clinically asymptomatic, 20% of those that actually demonstrate signs and symptoms can be easily confused with symptoms of other commonly presenting musculoskeletal disorders. Proper medical management can reduce patient's morbidity and further burden. A 50 years old diabetic Post-Coronary Artery Bypass Grafting gentleman had been suffering for left leg swelling, high grade fever and calf muscle pain for 5 days. He had absent Arteria Dorsalis Paedis pulse on left foot, Positive Homan sign and Wells score is 7. His left leg was hugely swelled. He had normal leg hair distribution. Duplex study of Left Leg-Deep Vein Thrombosis in left lower limb (Popliteal segment) with sign of recanalization. He is also a patient of anemia of chronic disease due to hemorrhoid. Several investigations have done to find the cause of his chronic anemia. His treatment was meticulous with complete bed rest, elevation of left lower limb, heparinization, oralrivaroxaban. He had rapid recovery following treatment. Post-Coronary Artery Bypass Grafting patient should be given post-operative enoxaparin (Low molecular weight Heparin) or Heparin for 3-5 days. Early diagnosis of the disease condition reduces morbidity. Combined treatment with Rivaroxaban and Heparin is of great clinical value and outcome in a case of Post-Coronary Artery Bypass Grafting Deep Vein Thrombosis patient.

Right Atrial Myxoma: An Uncommon Presentation

There are two types of tumors found in the cardiac chamber. These are divided into primary intra-cardiac tumors and secondary intra-cardiac tumors. Primary intra cardiac tumors are rare and among them 29% are myxomas. Majority of them are found in the left atrium. Here, we report a case of a myxoma in the right atrium with hepatomegaly and Hepatitis B virus infection. The coexistence of all these conditions is very rare. A 52 years old patient presented with history of shortness of breath on exertion along with fever and generalized weakness for 6 months which aggravated lately for last 2 months. He was then taken for better medical care and hospitalization. On cardiac evaluation he had soft S1 and S2 over the tricuspid region on the right lower parasternal region. He had bilateral mild pitting pedal edema. On further examination, it was revealed that he had mild tender hepatomegaly with jaundice. His blood analysis for HBsAg was positive. Echocardiogram showed right atrial myxoma of 14.3cm² almost completely occupying the right atrium and even protruding into the Inferior Venacava however not fully obstructing it. The inferior vena cava size was mildly dilated (22mm). Abdominal ultrasound report showed hepatomegaly (17.6cm) with coarse hepatic parenchyma. In this report, we emphasize the rarity of myxoma in the Right Atrium, its difficult diagnosis because of the location and the atypical presentation in the echocardiograph.

Van Wyk and Grumbach Syndrome: An Unusual Presentation of Hypothyroism

An 18 years-old-girl presented one and half years back with the complaints of short stature, retarded growth, and menorrhagia with sudden severe lower abdominal pain; was diagnosed as bilateral ovarian cysts and underwent bilateral ovarian cystectomy. Later on she was incidentally diagnosed as a case of hypothyroidism when she had been experiencing slowly enlarging left lower abdominal mass with dull ache for the 5 month and then was transferred to the department of Endocrinology for further evaluation. Detailed work up revealed her short stature with obesity, delayed bone age and other features of hypothyroidism which was confirmed by thyroid function testing. She had enlarged left ovary with multiple follicles as shown in ultrasonography. Magnetic resonance imaging (MRI) showed sellar mass which was suspicious of macroadenoma. Levothyroxine replacement was started and she had a dramatic improvement of her problems with disappearance of the ovarian cysts and sellar mass.

Use of Acute Physiology and Chronic Health Evaluation (APACHE)-II and Red Cell Distribution Width (RDW) for Assessment of Mortality of Patients with Sepsis in ICU

Critically ill patients of Intensive Care Unit (ICU) need highest level of monitoring, intense nursing care and integrated management which are very expensive and consume significant part of hospital resources. Prediction of outcome from disease has become an essential component of health science. So, various scoring systems have been developed to predict outcome of critically ill patients in ICU. There is no perfect model of severity score to predict ICU mortality. Search for new system is still remaining as continuous efforts to find the best model to get accurate information about the prognosis and outcome of critically ill patients. This observational prospective cohort study was carried out in ICU of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from March 2015 to September 2015 to evaluate the ability of mortality prediction of Acute Physiology and Chronic Health Evaluation (APACHE)-II after adding RDW. Total 62 patients, clinically diagnosed as sepsis with positive culture were included in this study after analyzing selection criteria. APACHE II score model was compared with APACHE II plus RDW score model in relation to mortality outcome assessment. Sensitivity, Specificity, Positive predictive value (PPV), Negative predictive value (NPV) and Receiver Operating Characteristic (ROC) curve were used as parameter to compare the predictive ability of the two models. The derived model APACHE II- RDW was found with higher predictive power (Pearson's correlation coefficient - 0.915) than APACHE II (Pearson's correlation coefficient - 0.885) in relation to mortality (p<0.01). Accuracy was compared by using Receiver Operating Characteristic (ROC) curve between the two models and AUROC was found higher (AUC-0.87) in case of new model compared with conventional model (AUC-0.85). So combination of RDW with APACHE-II increases the predictive ability of the scoring model in relation to mortality.

Detection of Human Papilloma virus by Molecular method from Patients Attending at Colposcopy Clinic of Mymensingh Medical College Hospital, Mymensingh

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.

Ramadan Perspective Epidemiology and Education in Diabetes (RAPEED) Study

Ramadan fasting is one of the five pillars of Islam and is obligatory for all healthy adult and adolescent Muslims. A significant number of patients with diabetes observe fasting during Ramadan. The objectives of this Ramadan Perspective Epidemiology and Education in Diabetes (RAPEED) study were to find out the current knowledge, attitude, and practices about Ramadan fasting among people with diabetes in Bangladesh. This retrospective cross-sectional study recruited 648 subjects with diabetes mellitus attending the Endocrinology outpatient department of a tertiary level hospital of Bangladesh within two months of the end of Ramadan in 2016. Socio-demographic data, data related to diabetes treatment, complications and co-morbidities; changes in lifestyle and diabetes treatment during Ramadan and frequency of hypoglycemia were collected from all. The mean age of the study population was 50.32±12.1 years and the majority (98.6%) had type 2 diabetes and 63.9% were overweight or obese. The majority (89.35%) of the patients fasted in Ramadan and among them, more than half of the fasters received physicians' advice for Ramadan fasting (60.6%) and changed diabetes medication (69.90%) during Ramadan. Although the amount of total food consumption was unchanged in more than one half (60.6%) of the fasters, majority of them reduced sugar-sweet intake (75.5%), increased fluid drinking (75.8%) and decreased physical activity (75.8%) during the month. A large portion (37.48%) of them did not check blood glucose and more than half (54.06%) of fasters failed to visit their physicians during Ramadan. Among them 14.85% experienced mild to moderate episodes of hypoglycemia and none had severe hypoglycemia and the most (61.6%) episodes of hypoglycemia occurred in the late evening. Hypoglycemic episodes were more frequent among insulin users, patients who had received fasting advice from physicians and in those who had adjusted diabetes drugs before Ramadan fasting. Safe Ramadan fasting is a great challenge not only for the patients but also the consulting physicians. Current study reflects the necessity of both physicians' expertise and patients' awareness for safe fasting.

Clinical Presentation of Adult Pulmonary Tuberculosis (PTB): A Study of 103 Cases from a Tertiary Care Hospital

Tuberculosis, one of the oldest diseases known to affect humans, is a major cause of death worldwide. The disease, which is caused by the bacteria Mycobacterium tuberculosis complex, usually affects the lungs, although other organs are involved in up to one-third of causes. If properly treated, tuberculosis caused by drug-susceptible strains is curable in virtually all cases. If untreated, the disease may be fatal within five years in 50-65% of cases. Transmission usually takes place through the airborne spread of droplet nuclei produced by patients with infectious pulmonary tuberculosis. This cross sectional observational study was conducted to detect various clinical presentations of pulmonary tuberculosis patients in the Department of Medicine, Sir Salimullah Medical College and Hospital from January 2009 to December 2009. Sample was selected through inclusion methods from patients who was admitted in to hospital and confirmed as pulmonary tuberculosis after appropriate investigations and who gave informed written consent was finally enrolled in this study. A total 103 patients were selected for the study. Out of 103 cases 34.9% were above 50 years old, followed by 26.2% between 30-40 years old, 22.3% between 40-50 years old and remaining 16.5% bellow 30 years old. The male to female ratio was roughly 1.2:1. The most of the patients were housewife and farmer which were 31% and 28.1% respectively. The most of the patients came from low socio-economic group. About 55.3% cases were smoker and 43.7 were non smoker. Among the frequency of symptoms 73.7% were chronic cough for above one month followed by 70.8% were low grade fever, 41.8% were night sweats and the 2% were admitted in hospital for other complaints and after evaluation diagnosed as PTB. The most of the patients about 67% were suffering from less than six weeks duration. Among the physical findings the 67% cases were lost significant weight, 56.3% had fever and 56.3% had apical crepitation over chest. There was sputum positive for acid fast bacilli about 64.7%. The traditional TB diagnosis methods are time consuming and the most of the patients are poor in our country, they are unable to afford the modern costly investigations. Therefore we should more emphasis on clinical examinations, so that we can diagnosis pulmonary TB rapidly and can start treatment as early as possible.

Helicobacter Pylori Stool Antigen Assay in Hyperemesis Gravidarum

Hyperemesis gravidarum is the most severe form of nausea and vomiting in pregnancy that seriously affects the pregnancy outcome. It is a disease with unknown etiology and varieties of contributing factors like hormonal changes, psychological and immunological factors. A significantly high prevalence of Helicobacter pylori among pregnant women with Hyperemesis gravidarum has been revealed recently. A descriptive, cross-sectional study was carried out at antenatal ward, Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital, Mymensingh for a period of twenty-one months among purposively selected thirty-six patients with Hyperemesis gravidarum with a view to assess the involvement of H. pylori in Hyperemesis gravidarum. Data were collected through interview, physical examinations and laboratory investigations by using case record form. Statistical analysis was performed using SPSS version 20.0 for Windows. Highest number 16(44.44%) of respondents were in age group 20 to 24 years with a mean of 23.81 years and a standard deviation (SD) of 4.55 years. Majority 29(80.56%) of the women had education less than 12 years, as many as 28(77.78%) women were housewives, and at least 14(38.89%) women had unplanned pregnancies. An overwhelming majority 29(80.56%) of women had their pregnancy duration between 8 to 12 weeks with a mean duration of 10.64 weeks and a standard deviation of 2.35 weeks. Majority 20(55.56%) of women were pregnant for first time, as many as 19(52.78%) women had duration of illness for 5 to 9 weeks. Of 16 multi-gravid women, 7(43.75%) had history of similar condition in their previous pregnancies. As many as 9 (25.00%) women had family history of similar condition in their mothers and sisters. First trimester was time of manifestation of the condition.At least 11 (30.56%) stool samples were positive for H. pylori stool antigen. Family history of Hyperemesis gravidarum and presence of H. pylori stool antigen are statistically associated (p<0.05). Pregnancy at young age, low educational status of women, nulliparity, unplanned pregnancy, past history, family history and H. pylori infection are the identified risk factors of Hyperemesis gravidarum.

Diagnosis of Dermatophytosis by Conventional Methods and Comparatative analysis of Sabouraud Dextrose Agar and Dermatophyte Test Medium for Isolation of Dermatophytes

Dermatophytosis is a fungal disease which ranked as one of the most common cutaneous condition in all over the world. The aim of this cross sectional observational study is to identify the etiological agent of dermatophytosis and comparison of Sabouraud dextrose agar (SDA) and Dermatophyte test medium (DTM) for the primary isolation of dermatophytes among the clinically suspected cases of dermatophytosis from the outpatient Department of Dermatology and Venereology, Mymensingh Medical College Hospital from July 2013 to December 2015. Two hundred thirty clinically suspected cases of dermatophytosis were subjected in this study. Sixty three cases (27.4%) were positive for fungus in direct microscopy while 53(23%) were culture positive. Trichophyton rubrum (83%) was found common etiological dermatophyte species followed by Trichophyton mentagrophytes 5(9.4%) and Epidermophyton floccosum 4(7.5%). There was no statistically significant difference between the SDA and DTM (p<0.01) in primary isolation of dermatophytes.

Clinical Evaluation of Bucco-lingual Crestal Bone Remodeling in Mandibular Posterior Implants placed immediately and Delayed into Extraction Sites

The objective of this cross sectional study was to evaluate the bucco-lingual crestal bone remodeling in mandibular posterior implants placed immediately and delayed into extraction sites and carried out in the department of Prosthodontics of Dhaka Dental College and Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from July 2010 to July 2014. Forty patients were evaluated in this study; of them 25(62.5%) patients were males and 15(37.5%) were females with age range from 24 to 70 years. At first surgery during implant placement the mean distance from buccal bone to lingual bone was 11.11mm for immediate implants and 9.265mm for delayed implants. At second-stage surgery the mean distance from buccal bone to lingual bone was 9.765mm for immediate implants and 6.25mm for delayed implants. The mean±SD change of bone reduction at second surgery was 1.28±0.31 for immediate implants and 3.01±0.33 for delayed implants. Unpaired t test was done for statistical analysis and p value was less than 0.05. So, the changes were statistically significant.
