Outcomes following percutaneous coronary intervention and coronary artery bypass grafting surgery in Chinese, South Asian and White patients with acute myocardial infarction: administrative data analysis

Background

Little is known on whether there are ethnic differences in outcomes following percutaneous coronary intervention (PCI) and coronary artery bypass grafting surgery (CABG) after acute myocardial infarction (AMI). We compared 30-day and long-term mortality, recurrent AMI, and congestive heart failure in South Asian, Chinese and White patients with AMI who underwent PCI and CABG.

Methods

Hospital administrative data in British Columbia (BC), Canada were linked to the BC Cardiac Registry to identify all patients with AMI who underwent PCI (n = 4729) or CABG (n = 1687) (1999–2003). Ethnicity was determined from validated surname algorithms. Logistic regression for 30-day mortality and Cox proportional-hazards models were adjusted for age, sex, socio-economic status, severity of coronary disease, comorbid conditions, time from AMI to a revascularization procedure and distance to the nearest hospital.

Results

Following PCI, Chinese had higher short-term mortality (Odds Ratio (OR): 2.36, 95% CI: 1.12-5.00; p = 0.02), and South Asians had a higher risk for recurrent AMI (OR: 1.34, 95% CI: 1.08-1.67, p = 0.007) and heart failure (OR 1.81, 95% CI: 1.00-3.29, p = 0.05) compared to White patients. Risk of heart failure was higher in South Asian patients who underwent CABG compared to White patients (OR (95% CI) = 2.06 (0.92-4.61), p = 0.08). There were no significant differences in mortality following CABG between groups.

Conclusions

Chinese and South Asian patients with AMI and PCI or CABG had worse outcomes compared to their White counterparts. Further studies are needed to confirm these findings and investigate potential underlying causes.

Sex differences in acute coronary syndrome symptom presentation in young patients

IMPORTANCE

Little is known about whether sex differences in acute coronary syndrome (ACS) presentation exist in young patients and what factors determine absence of chest pain in ACS presentation.

OBJECTIVES

To evaluate sex differences in ACS presentation and to estimate associations between sex, sociodemographic, gender identity, psychosocial and clinical factors, markers of coronary disease severity, and absence of chest pain in young patients with ACS.

DESIGN, SETTING, PARTICIPANTS

We conducted a prospective cohort study of 1015 patients (30% women) 55 years or younger, hospitalized for ACS and enrolled in the GENESIS PRAXY (Gender and Sex Determinants of Cardiovascular Disease: From Bench to Beyond Premature Acute Coronary Syndrome) study (January 2009-September 2012).

MAIN OUTCOMES AND MEASURES

The McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey was administered during hospitalization.

RESULTS

The median age for both sexes was 49 years. Women were more likely to have non-ST-segment elevation myocardial infarction (37.5 vs 30.7; P = .03) and present without chest pain compared with men (19.0% vs 13.7%; P = .03). Patients without chest pain reported fewer symptoms overall and no discernable pattern of non-chest pain symptoms was found. In the multivariate model, being a woman (odds ratio [OR], 1.95 [95% CI, 1.23-3.11]; P = .005) and tachycardia (OR, 2.07 [95% CI, 1.20-3.56]; P = .009) were independently associated with ACS presentation without chest pain. Patients without chest pain did not differ significantly from those with chest pain in terms of ACS type, troponin level elevation, or coronary stenosis.

CONCLUSIONS AND RELEVANCE

Chest pain was the most common ACS symptom in both sexes. Although women were more likely to present without chest pain than men, absence of chest pain was not associated with markers of coronary disease severity. Strategies that explicitly incorporate assessment of common non-chest pain symptoms need to be evaluated.

Risk factors of non-alcoholic fatty liver disease

This case control study was carried out in Mymensingh Medical College Hospital, Mymensingh, Bangladesh and Dhaka Medical College Hospital, Dhaka, Bangladesh from November 2010 to October 2011 to find out the risk factors of non-alcoholic fatty liver disease. A total of 90 participants (45 cases and 45 controls) were included. A higher proportion of patients with age >45 years were found in case group compared to control (51.1% vs. 15.6%). The mean age was significantly higher in case group 49.8±12.6 years. Males demonstrated their predominance in both case (62.2%) and control (68.9%) groups, although the two groups did not differ in terms of sex distribution. Body mass index demonstrates that 26.7% of patients in case group were of normal weight, 46.7% overweight and 26.7% obese. In the control group, two-thirds (68.9%) of the patients were of normal weight and 24.4% overweight and 7.8% obese. Diabetes and hypertension were significantly present in the case group than those in control counterparts 75.6% vs. 15.6% and 86.7% vs. 15.6 % respectively. The mean fasting blood glucose, ALT, total cholesterol and triglycerides were significantly higher in case group compared to control group 7.8±1.3 vs. 5.4±2.5mmol/L (p<0.001); 39.1±12.4 vs. 30.3±14.1IU/L, (p=0.002); 239.9±14.3 vs. 183.3±11.4mg/dl, (p<0.001) and 183.6±12.5 vs. 133.5±16.0mg/dl, (p<0.001) respectively. However, no significant difference was observed between the case and the control groups in terms of HDL cholesterol (35.9±1.2 vs. 38.0±1.1mg/dl, p=0.203). Majority of the patients in case group (88.9%) exhibited increased echogenicity of liver on ultrasonogram as opposed to 15.6% in the control group.

Prediction of oesophageal varices in cirrhosis of liver patients by serum ascitic albumin gradient

This hospital based observational study was carried out to evaluate the relation between serum ascitic albumin gradient and oesophageal varices in cirrhosis of liver disease patient. This was a hospital based observational study on 50 cases of diagnosed cirrhosis of liver disease patients in department of medicine of Mymensingh medical college Hospital, Mymensingh, Bangladesh from 8th January 2012 to 07th July 2012 for a period of 6 months. The study showed age frequency 5(10%) were from 21-30 years, 15(30%) were from 31-40 years 15(30%) were from 40-50years, and 15(30%) were from ≥51 years of age. Out of 50 patients, 38(76%) were male and 12(24%) were female patients. The etiology of liver cirrhosis was hepatitis B virus in 22(44%), hepatitis C virus in 4(8%), alcohol in 1(2%) and others in 23(46%) patients. Twenty four (48%) patients had SAAG value 1.1-1.49, 21(42%) patients had SAAG value 1.5-1.99, 5(10%) patients had Serum Ascitic Albumin Gradient (SAAG) value >2.0 and 16(32%) patients had no oesophageal varices, 11(22%) patients had small straight varices (F1) esophageal varices, 18(36%) patients had less than one-third of the esophageal lumen (F2) oesophageal varices, 5(10%) patients had more than one-third of the esophageal lumen (F3) esophageal varices. The degree of SAAG demonstrate significant statistical association with presence or absence of oesophageal varices (p=0.023) and grades of the oesophageal varices (p=0.001) in patients with cirrhosis of liver disease. So, it was predicted that the presence of oesophageal varices in cirrhosis of liver disease patients with high SAAG without performing endoscopy of upper GIT.

Risk factors, quality of care and prognosis in South Asian, East Asian and White patients with stroke

Background

Stroke has emerged as a significant and escalating health problem for Asian populations. We compared risk factors, quality of care and risk of death or recurrent stroke in South Asian, East Asian and White patients with acute ischemic and hemorrhagic stroke.

Methods

Retrospective analysis was performed on consecutive patients with ischemic stroke or intracerebral hemorrhage admitted to 12 stroke centers in Ontario, Canada (July 2003-March 2008) and included in the Registry of the Canadian Stroke Network database. The database was linked to population-based administrative databases to determine one-year risk of death or recurrent stroke.

Results

The study included 253 South Asian, 513 East Asian and 8231 White patients. East Asian patients were more likely to present with intracerebral hemorrhage (30%) compared to South Asian (17%) or White patients (15%) (p<0.001). Time from stroke to hospital arrival was similarly poor with delays >2 hours for more than two thirds of patients in all ethnic groups. Processes of stroke care, including thrombolysis, diagnostic imaging, antithrombotic medications, and rehabilitation services were similar among ethnic groups. Risk of death or recurrent stroke at one year after ischemic stroke was similar for patients who were White (27.6%), East Asian (24.7%, aHR 0.97, 95% CI 0.78-1.21 vs. White), or South Asian (21.9%, aHR 0.91, 95% CI 0.67-1.24 vs. White). Although risk of death or recurrent stroke at one year after intracerebral hemorrhage was higher in East Asian (35.5%) and White patients (47.9%) compared to South Asian patients (30.2%) (p=0.002), these differences disappeared after adjustment for age, sex, stroke severity and comorbid conditions (aHR 0.89 [0.67-1.19] for East Asian vs White and 0.99 [0.54-1.81] for South Asian vs. White).

Conclusion

After stratification by stroke type, stroke care and outcomes are similar across ethnic groups in Ontario. Enhanced health promotion is needed to reduce delays to hospital for all ethnic groups.

A case of Gaucher's disease progressing to liver cirrhosis

We are going to present a 17 year old female with Gaucher's disease. The patient presented with fever, cough, respiratory distress & abdominal heaviness. There was mild pallor, redness of palm of hands & raised temperature. Liver was hugely enlarged along with splenomegaly. X-ray chest showed non specific bronchiectatic change in both lungs. Ultrasonography of abdomen revealed marked hepatosplenomegaly with no ascites. Bone marrow examination showed cellular marrow with plenty of megakaryocytes. Most of the cells were smear cells & there was histiocytes proliferation & infiltration of bone marrow by small atypical cells. Histologically, lipid was found in hepatocytes in moderate amount. The portal areas showed high lipid contents in macrophages. Different clinical findings & incidental diagnosis of lipid storage disease submerged us in diagnostic dilemma. We give conservative treatment with antibiotic cefuroxime, syrup lactulose & vitamins and this patient was improved.

Pattern of poisoning in a tertiary level hospital

This cross sectional observational study was carried out in the Department of Medicine, Mymensingh Medical College Hospital over a period of 4 months from January 2012 to April 2012 to assess the clinico-epidemiological condition of different types of poisoning and to evaluate immediate hospital outcome. Suspected case of poisoning aged 12 years or above of either sex was included. Patients of paediatric age group, having other co-morbid condition and died before clinical evaluation were excluded. This study revealed that rural people (76.9%), aging 20-30 years (46.3%) were mostly affected in poisoning. Patients belong to low socioeconomic group (65.3%), illiterate (26.5%) and educated up to primary level (29.9%) were mostly identified. Regarding the occupation this study showed student (30.6%) and farmer (25.2%) were predominantly involved. In this series organophosphorus compound (63.9%) poisoning was in the top of the list followed by benzodiazepine (6.8%). Suicidal attempt (81.6%) was found as a motive of poisoning in maximum cases. Among the precipitating factors quarrel with spouse, girl or boy friend (46.9%) were significant in number. In this study outcome was measured as complete recovery (92.5%) and death (3.4%).

The 2013 Canadian Hypertension Education Program recommendations for blood pressure measurement, diagnosis, assessment of risk, prevention, and treatment of hypertension

We updated the evidence-based recommendations for the diagnosis, assessment, prevention, and treatment of hypertension in adults for 2013. This year's update includes 2 new recommendations. First, among nonhypertensive or stage 1 hypertensive individuals, the use of resistance or weight training exercise does not adversely influence blood pressure (BP) (Grade D). Thus, such patients need not avoid this type of exercise for fear of increasing BP. Second, and separately, for very elderly patients with isolated systolic hypertension (age 80 years or older), the target for systolic BP should be < 150 mm Hg (Grade C) rather than < 140 mm Hg as recommended for younger patients. We also discuss 2 additional topics at length (the pharmacological treatment of mild hypertension and the possibility of a diastolic J curve in hypertensive patients with coronary artery disease). In light of several methodological limitations, a recent systematic review of 4 trials in patients with stage 1 uncomplicated hypertension did not lead to changes in management recommendations. In addition, because of a lack of prospective randomized data assessing diastolic BP thresholds in patients with coronary artery disease and hypertension, no recommendation to set a selective diastolic cut point for such patients could be affirmed. However, both of these issues will be examined on an ongoing basis, in particular as new evidence emerges.

The etiologic role of human papillomavirus in penile cancers: a study in Vietnam

Background:

We investigated the aetiologic role of human papillomavirus (HPV) in 120 penile squamous cell carcinomas (PSCCs) from Vietnam.

Methods:

Human papillomavirus DNA was detected by PCR using SPF10 primers and a primer set targeting HPV-16 E6. The INNO-LiPA HPV genotyping kit was used to determine genotype. Human papillomavirus-16 viral load and physical status were determined by real-time PCR. P16^INK4A protein expression was investigated by immunohistochemistry.

Results:

Human papillomavirus DNA was detected in 27 of 120 (23%) PSCCs. The most frequently detected genotype was HPV-16 (24 of 27 cases, 89%). In 16 of 18 (89%) HPV-16-positive cases, the HPV DNA was considered to be integrated into the host genome. The geometric mean of the HPV-16 viral load was 0.4 copies per cell. P16^INK4A overexpression was significantly related to PSCCs infected with high-risk HPV (P=0.018) and HPV-16 copy numbers (P<0.001).

Conclusion:

Human papillomavirus-16 DNA integration and p16^INK4A overexpression in high-risk HPV detected PSCCs suggested an aetiologic role of high-risk HPV in the development of PSCCs.

Comparison of computed tomographic and cytopathological findings in the evaluation of adult orbital mass

An observational study was conducted to demonstrate the role of Computed Tomographic (CT) scan to detect clinically suspected adult orbital mass in 47 patients which could not be differentiated clinically. The CT findings were compared and correlated with the findings of fine needle aspiration cytology (FNAC) or histopathology. CT diagnosis of optic nerve sheath meningioma were 12 cases, among them only nine cases confirmed cytopathologically as meningioma and rest three as lymphoma. Among ten cases of hemangioma, eight cases were confirmed cytopathologically as cavernous hemangioma and rest two were pseudotumor and chronic inflammatory lesion. Seven cases diagnosed as pseudotumor in CT were confirmed cytopathologically. Seven cases diagnosed as paranasal sinus masses with orbital extension (nasopharyngeal angiofibroma) in CT were confirmed cytopathologically. Among three cases of thyroid ophthalmopathy diagnosed in CT, only two cases confirmed cytopathologically and rest one cytopathologic diagnosis was not possible due to inadequate tissue supply during FNAC. Two cases of chronic inflammatory lesion diagnosed in CT, also confirmed cytopathologically. Two cases of metastatic lesion diagnosed in CT, also confirmed cytopathologically. Two cases of lacrimal gland tumor diagnosed in CT, also confirmed cytopathologically i.e., pleomorphic adenoma. Two cases of melanoma diagnosed in CT, only one confirmed cytopathologically and rest one cytopathologic diagnosis was not possible due to frank blood came out during FNAC. Pseudotumors were subsequently diagnosed the non-diagnostic cases on the basis of clinical and radiological findings. It is evident from these findings that CT is a useful modality in the diagnosis of adult orbital masses.

Diagnostic evaluation of supraclavicular lymphadenopathy

Patients presented with the supraclavicular lymphadenopathy in the medicine department have a strong suspicion of serious illness like tuberculosis, sarcoidosis, toxoplasmosis and malignancy of lymphnode, blood, lung, upper GIT, breast, ovary, testes, and other sites of body. This prospective type of observational study carried out in the indoor and out patient department of medicine of Mymensingh Medical College Hospital over a period of 6 month from April 2011 to September 2011 to diagnose the causes of supraclavicular lymphadenopathy. Patient of either sex, 18 years or above presented with supraclavicular lymphadenopathy were included. Biopsy or FNAC were done. The study showed that mean age of the patient of supraclavicular lymphadenopathy that finally diagnosed as malignant was 49.7 years and that of non malignant was 33.7 years. Male patient have suffered more (60%) from malignant disease than that of female patient (40%). Discrete, hard, non tender either fixed or non fixed supraclavicular lymphadenopathy was found malignant (18 of 18 cases, 100%) and discrete, firm, tender lymphnode were found non malignant (5 of 5 cases, 100%). Increased frequency (11 of 28, 39.3%) of granulomatous inflammation from the tuberculoid lymphadenitis were found among the patient undergone supraclavicular lymphnode biopsy. FNAC result was also of simillar type and finally it was found that frequency of tuberculosis (20 of 53, 37.7%) was highest and bronchial carcima was the second most frequent diagnosis (14 of 53, 26.4%). This study showed that supraclavicular lymphadenopathy is associated mostly with serious disease like tuberculosis and malignancy.

Relation of different grades of esophageal varices with Child-Pugh classes in cirrhosis of liver

This cross-sectional observational study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh over a period of 6 months from October 2011 to April 2012 and was carried out to evaluate the relation of different grades of esophageal varices with Child-Pugh classes of cirrhosis of liver patients. A total 37 patients were included. Child-Pugh score and esophageal varices of each patient were noted. Relation was carried out using the Chi-square test through determining the association of different variables. P value <0.05 was considered significant. Among 37 patients, 27(73%) were male and 10(27%) were female and their frequency of age were found, 7(18.9%) from 18-38 years, 18(48.7%) from 39-59 years and 12(32.4%) from 60 years of age and above. The etiology of liver cirrhosis revealed 18(48.7%) hepatitis B virus, 3(8.1%) hepatitis C virus and 16(43.2%) others causes. Child-Pugh classes were observed 3(8.2%) Class A, 17(45.9%) Class B and 17(45.9%) Class C and grades of esophageal varies were 13(35.1%) F1, 20(54.1%) F2 and 4(10.8%) F3 patients among total. A statistically significant positive relation was found that higher grade of esophageal varices was seen in the more advanced class of Child-Pugh classes with a p value 0.001.

Comparison of transabdominal and transvaginal sonography in the evaluation of uterine mass with histopathological correlation

A cross-sectional study was conducted to demonstrate the role of transvaginal (TVS) and transabdominal sonography (TAS) to detect clinically suspected uterine mass in 53 patients which could not be differentiated clinically. The sonographic findings were compared and correlated with the findings of histopathology. TAS and TVS revealed 20(37.7%) & 20(37.7%) had leiomyoma, 12(22.6%) & 14(26.4%) had Ca cervix, 6(11.3%) & 7(13.2%) had endometrial carcinoma, 1(1.9%) & 1(1.9%) had hydatidiform mole respectively. TAS revealed 5(9.4%) had thickened endometrium, and no detectable mass were detected in 9(17.0%) cases. TVS revealed polyp in 7(13.2%), and no detectable mass were detected in 4(7.5%) cases. Histopathologically confirmed leiomyoma were in 18(34.0%) cases, Ca cervix in 14(26.4%), endometrial carcinoma in 6(11.3%), adenomyosis in 1(1.9%), polyp in 7(13.2%), chronic cervicitis in 2(3.8%), hydatidiform mole in 1(1.9%) and no detectable mass were detected in 4(7.5%) cases. Sensitivity of TAS and TVS to diagnose uterine mass were 83.7% and 95.9%, specificity 25.0% and 50.0%, positive predictive value 93.2% and 95.9%, negative predictive value 11.1% and 50.0% and accuracy 79.2% and 92.5% respectively. Sensitivity of TAS & TVS to diagnose leiomyoma was 88.9% & 94.9%, specificity 88.6% & 91.4%, positive predictive value 80.0% & 85.0%, negative predictive value 93.9% & 97.0%, and accuracy 88.7% & 92.5% respectively. Sensitivity of TAS & TVS to diagnose Ca cervix were 57.1% & 78.6%, specificity 89.7% & 92.3%, positive predictive value 66.9% & 78.6%, negative predictive value 85.4% & 92.3%, and accuracy 81.1% & 88.7% respectively. So, uterine mass can be evaluated more accurately by TVS than TAS.

Fasting glycaemic and lipidaemic status in acute coronary syndrome patients within 24 hours of onset of chest pain

This is a descriptive type of cross sectional study done in Mymensingh Medical College Hospital during the period of June 2008 to November 2009 to estimate and analyze the fasting blood glucose (FBG) and fasting lipid profile of acute coronary syndrome (ACS) patients within 24 hours of onset of chest pain. Total 50 patients of either sex diagnosed as acute coronary syndrome whose fasting blood sample would have been collected within 24 hours of chest pain were included. Among 50 patients 42(84%) were male and 8(16%) were female. Age range was 30-80 years with a mean ± SD of 50.74 ± 12.05 years. Among 50 ACS patients, 9 patients (18%) suffered from unstable angina (US), 2(4%) from non-ST segment elevation myocardial infarction (NSTEMI) and 39(78%) suffered from ST segment elevation myocardial infarction (STEMI). Study results revealed 41(82%) patients had euglycemia (70-110 mg/dl), 2(4%) patients had impaired fasting glucose (IFG) (110-125 mg/dl), and 7(14%) patients had hyperglycemia (>126 mg/dl). Dyslipidemia found in 38(76%) patients. Among them total cholesterol (TC) >200mg/dl in 14(28%), decreased level of HDL-C (< 40 mg/dl in male and <50mg/dl in female) in 22(44%), increased level LDL-C ≥ 130 mg/dl in 13(26%), and TG >150 mg/dl was found in 16(32%) patients.

Congenital urogenital sinus anomaly without Adrenal Hyperplasia

Urogenital sinus anomaly is a mal-development of female urogenital system, usually associated with Congenital Adrenal Hyperplasia and may varied in presentation according to embryologic separation and length of sharing of common channel between vagina and urethra. We report a case of pure urogenital sinus anomaly of 2.5 years female child without any feature of Congenital Adrenal Hyperplasia or any other associated anomalies which is quite uncommon. The patient was diagnosed with thorough physical, biochemical, radiological and endoscopic evaluation. She had clitiromegaly, very poorly developed fused Labia minoras with a central hole, the length of common channel was about 2.5 cm and the level of vaginal confluence was at the mid portion of common channel. After in general counseling to parents, according to their desire she was operated. We performed Labialo-clitoro-vagino-urothroplasty and from post operative period to till now (after 3 months of operation) she is uneventful. Both functionally and cosmetically she is sound and her parents are also happy.

Leiomyoma of esophagus presenting as huge posterior mediastinal mass: 2 case reports

Smooth muscle tumors presenting as mediastinal soft tissue masses are rare and are often mistaken for other neoplasms. Benign tumors of the esophagus account for fewer than 1% of all esophageal tumors, the most common of which are leiomyomas. They are frequently located in the lower third of the esophagus. We report two cases of esophageal leiomyoma in the thoracic esophagus which were firstly presented as huge mediastinal mass with intermittent dysphagia and radiologically flecks of calcification.

Evaluation of anti-inflammatory potential of leaf extracts of Skimmia anquetilia

OBJECTIVE

To evaluate anti-inflammatory potential of leaf extract of Skimmia anquetilia by in-vitro and in-vivo anti-inflammatory models.

METHODS

Acute toxicity study was carried out to determine the toxicity level of different extract using acute toxic class method as described in Organization of Economic Co-operation and Development Guidelines No.423. Carrageenan (1% w/w) was administered and inflammation was induced in rat paw. The leaf extracts of Skimmia anquetilia were evaluated for anti-inflammatory activity by in-vitro human red blood cell (HRBC) membrane stabilization method and in-vivo carrangeenan-induced rat paw edema method.

RESULTS

The in-vitro membrane stabilizing test showed petroleum ether (PE), chloroform (CE), ethyl acetate (EE), methanol (ME) and aqueous extracts (AE) showed 49.44%, 59.39%, 60.15%, 68.40% and 52.18 % protection, respectively as compared to control groups. The in-vivo results of CE, EE and ME showed 58.20%, 60.17% and 67.53% inhibition of inflammation after 6h administration of test drugs in albino rats. The potency of the leaf extracts of Skimmia anquetilia were compared with standard diclofenac (10 mg/kg) which showed 74.18% protection in in-vitro HRBC membrane stabilization test and 71.64% inhibition in in-vivo carrangeenan-induced rat paw edema model. The ME showed a dose dependent significant (P< 0.01) anti-inflammatory activity in human red blood cell membrane stabilization test and reduction of edema in carrageenan induced rat paw edema.

CONCLUSIONS

The present investigation has confirmed the anti-inflammatory activity of Skimmia anquetilia due to presence of bioactive phytoconstitutes for the first time and provide the pharmacological evidence in favor of traditional claim of Skimmia anquetilia as an anti- inflammatory agent.

Hypothalamic hamartoma with precocious puberty: a case report

Hypothalamic hamartoma (HH) is one of the most important causes of central precocious puberty in male children. Hamartomas are malformations composed of ectopic gonadotropic hormone (GnRH) neurons which secrete pulsatile gonadotropin releasing hormone. They are generally observed in children under 3 years. A case of 11/3 year-old male child presented with premature development of secondary sexual characters i.e., growth of pubic and axillary hair, enlargement of penis and acne over the face for the last 5 months. On physical examination, his height was 1.02 m and his weight 18kg, enlarged penile length of which 58mm; testicles were enlarged in size right one measuring 32X25mm and the left 30X23mm. His hematological and other biochemical investigations revealed no abnormality. Plain radiographic examination revealed radiological bone age of about 8-9 years. Endocrinological findings were as follows: Follicle stimulating hormone (FSH): 1.5mIU/ml, Luteinizing hormone (LH): 9.1mIU/ml, Testosterone: 701ng/dl (Testosterone level less than 30ng/dl in prepubertal age). Thyroid function tests were normal. Patient showed no adrenal pathology on ultrasound and his testicular parenchyma was homogeneous echotexture with the size of 30X22X16mm on the right (volume 5.4ml) and 30X20X15mm on the left (volume 4.6ml). With above physical & endocrinological findings and age of the child, it was suspected as a case of central precocious puberty. Subsequently MR imaging of the brain done & showed an oval non-enhancing pedunculated hypothalamic mass arising from the tubercinereum that was iso to hypointense to brain parenchyma on T1 - and intermediate signal on T2-weighted images, 20X10X10mm in diameter, extending into suprasellar cistern. During follow up after 06 months of starting conservative medication with gonadotropin-releasing hormone (GnRH) analog (Leuprolide acetate), his progression of puberty has been arrested and the testosterone level 18ng/dl, which is normal for his age.

Comparative study on methotrexate and hydroxychloroquine in the treatment of rheumatoid arthritis

This study was done to see the efficacy and tolerability of methotrexate and hydroxychloroquine in the Treatment of Rheumatoid Arthritis. It was an open label controlled clinical trial, done in Mymensingh Medical college hospital. Fifty six patients were selected by random sampling method, 28 were included in methotrexate group and another 28 for hydroxychloroquine group using inclusion & exclusion criteria. Primary efficacy variables (DAS28, daily naproxen), secondary efficacy variables, and safety measurement variables studied both clinically & laboratory investigations. The data were analyzed by computer with the help of SPSS. The student's t test was used as test of significant. The mean age of the patients at diagnosis was almost identically distributed between methotrexate and hydroxychloroquine group (41.7±12.2 vs. 42.9±9.2 years, p=0.659). Disease activity at baseline was found to be almost homogeneous to each group except CRP which was observed to be significantly higher in methotrexate group than hydroxychloroquine group (p<0.001). Disease activity at 1 month of treatment reduced in the methotrexate group than those in hydroxychloroquine group (p<0.05 in each case). After 3 and 6 months of treatment, disease activity decreased significantly in both groups (p<0.001 and p<0.05 respectively). The average daily dose of NSAID (Naproxen) decreased significantly (p<0.001). Safety variables at 6 month were within normal physiological ranges and did not differ in groups (p>0.05) indicating that both methotrexate and hydroxychloroquine were effective and safe to use in rheumatoid arthritis. The difference in the incidence of adverse effects, total or individual, was almost nil.

Interventional radiology for the treatment of hepatic malignancy

Hepatic malignancies are commonly faced clinical problem. Non surgical minimally invasive therapies are current treatment goal. Interventional radiologists are going forwards with such minimally invasive but effective therapies by transarterial chemoembolization, radiofrequency ablation, percutaneous ethanol injection, cryoablation, laser ablation and upcoming promising procedures like focused ultrasound & gene therapy. Response rates of transarterial chemoembolization for primary and most metastatic tumors are 60-80% with survival rates of 70% at 1 year, 40% at 3 years, and 10% at 5 years. Percutaneous ethanol injection ablation is the most accepted minimally invasive method worldwide, for hepatocellular carcinomas less than 5 cm in diameter, the complete ablation rate is about 70-75%; in 5-8 cm diameter, encapsulated hepatocellular carcinomas, the rate is about 60%. RFA is becoming a widely used ablative technique for primary and secondary liver tumors, with a 52-67% complete ablation rate at 1 year and survival rates of 96%, 64%, and 40% at 1, 3 and 5 years, respectively. Meticulous patient selection, careful planning and execution are imperative and should be carried out with the participation of interventional and diagnostic radiologists, nuclear medicine specialists, and medical, surgical, and radiation oncologists. In terms of cost, equipment, technical efficiency, efficacy & repeated applicability percutaneous procedures particularly PEI & RFA can be carried out in Bangladesh.

Seasonal variation in types of stroke and its common risk factors

The present descriptive cross-sectional study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh over a period of one year during November 2009 to October 2010. The study was conducted to describe the variations in types of stroke (ischemic stroke and hemorrhagic stroke) during summer and winter. An attempt was also made to observe the frequency of common risk factors of stroke by seasons. A total of 292 patients of any age irrespective of sex fulfilling the WHO criteria of acute stroke and confirmed by CT scan were selected from consecutive admission in the Department of Medicine, Mymensingh Medical College Hospital. Detail history and thorough clinical examinations were done. Routine and relevant investigations were carried out. The mean age of the patients was 59.9±14.3 years. A male preponderance was observed in the study. In summer 66% of patients and in winter 34% of patients were presented. Ischemic stroke was present in 54.1% patients and 45.9% patients had haemorrhagic stroke. The study found that the frequency of ischaemic stroke during summer (62.4%) was significantly greater than that during winter (37.8%). The frequency of haemorrhagic stroke during winter (62.2%) was significantly greater than that during summer (37.6%). Hypertension was the most important risk factor and other risk factors were smoking, diabetes mellitus, tobacco chewing, ischemic heart disease, dyslipidemia, oral contraceptive pill, alcohol consumption, atrial fibrillation and past history of stroke. Increasing age was also noted as a risk factor (60.7% >60 years). Most of the risk factors were homogenously distributed between two seasons and between ischemic and haemorrhagic group. Hypertension was significantly higher in haemorrhagic stroke patients compared to ischemic stroke patients.

Correlation of triglyceride level with acute coronary syndrome

The study was aimed to find out the correlation of serum triglyceride level with acute coronary syndrome. This cross sectional study was conducted in the department of cardiology, Mymensingh Medical College Hospital, from August 2009 to May 2010. Socio-demographic characteristics, smoking habit, hypertension, serum total cholesterol level, serum HDLc, Serum LDLc, TG level were important variable considered. A total number of 100 respondents consisted of 50 cases (patient) and 50 healthy persons (control). Investigations included ECG, cardiac enzyme (troponin I), FBS and lipid profile. The data were analyzed by computer with the help of SPSS. Chi-square Test, T-test & ANOVA test were used as test of significance. The mean level of TG in acute coronary syndrome (ACS) patients (cases) was 168.2±58.0 mg/dl and in control were 141.2±45.3 mg/dl. So serum TG level is significantly higher in patients with ACS (p=0.01). In multivariate regression analysis, there was a significant association of elevated TG with risk of ACS (relative risk) is the highest, compared with the lowest quarantile = 1.011; 95% confidence interval (CI = 1.002 - 1.020; P for trend = 0.01). The relation of TG level to HDLc was a strong predictor of ACS (RR in the highest) compared with lowest quarantile = 0.02; (95% CI = 0.003 - 0.173; P for trend <0.0001). The study revealed that high level of serum triglyceride is associated with ACS. Categorization of patients with ACS on the basis of TG level may be helpful for risk stratification and management.

Clinical profile of periodic paralysis

This cross sectional descriptive study was done to find out common clinical presentations, etiologies and laboratory investigation abnormalities in patients of periodic paralysis. Study was carried out in 30 patients with an age range from 8 to 70 years who were enrolled from July 2008 to June 2009 in Mymensingh Medical College Hospital (MMCH) medicine unit. Individuals who were admitted with sudden onset generalized muscle weakness, had history of previous attack and serum potassium level <3mmol/l or >5.5mmol/l were included in this study. In this series, majority of the patients were male (66.67%). Male: female ratio was approximately 2:1. The mean age of the patients was 27.4±4.5 years. Majority (26.67%) of them were in age range of 31-40 years. About 30% of the patients experienced the first attack of paralysis at the age of 20-24 years. Majority of patients (53%) were from middle class family with occupation of private service (26.66%) and farmer (20%). Positive family history was reported in 20% of patients. Regarding the precipitating factors, majority of patients (83.3%) were related to high carbohydrate meal, 56.67% related to temperature, 41.67% to exercise. Flaccid muscle weakness with variables muscle power (MRC grade 4/5 to 2/5 in 60% and 1/5 to 0/5 in 40%) was found. Cerebellar functions, all modalities of sensations and functions of cranial nerves were intact in all patients. In this series, laboratory investigations revealed reduced serum potassium level (<3mmol/l) in 90% of patients. Serum potassium value >5.5mmol/l was found in only 3.33% of patients. Creatine kinase (MM) was raised in 23% of the patients and Thyroid stimulating hormone (TSH) level was 0.8-2mmol/l in 6% of the patients. More than half of the patients (56%) showed variable ECG changes. Impaired nerve conduction function was found in 28.00%. So, careful history taking, meticulous clinical examination and simple laboratory investigations is sufficient to make a prompt diagnosis and rapid management of patients with periodic paralysis.
