    This study evaluated the validity of panoramic radiography and cone beam computed tomography (CBCT) in the assessment of mandibular canal and impacted third molar. In this descriptive-analytical study, 58 mandibular third molars from 42 patients who showed a close relationship between impacted third molar and canal on panoramic radiographs were selected. They were then classified into seven radiographic markers in panoramic radiographs (superimposition, darkening of the root, interruption of the white lines, root narrowing, canal diversion, canal narrowing, and also closed distance in OPG <1mm). The groups of markers were further assessed with CBCT to see presence or absence of contact. The three most common markers seen in panoramic images are superimposition, interruption of white line and root darkening. In CBCT, superimposition marker always presented higher frequency of contact with canal compared to non-contact group. There are 31% of teeth presented with interruption of white lines and there are 29.3% of teeth presented with superimposition. About 55.6% and 35.3% of the impacted mandibular third molars which indicated interruption of white lines and superimposition also indicated contact in the CBCT respectively. Presence or absence of radiological sign in panoramic radiography was not properly predict a close relationship with third molar and it is suggested that in case of tooth-canal overlapping, the patient should be referred for CBCT assessment.

    Globally, rotaviruses are the single most important etiologic agents of severe childhood dehydrating diarrhea that accounts for more than 125 million of cases, 25-55% of all hospital admissions for diarrhea and ≈600,000 deaths every year. In Bangladesh, while overall diarrhea related deaths are declining, the proportion of diarrhea deaths due to rotavirus is increasing. This study was aimed at estimating the burden of rotavirus diarrhea and isolating the genotypes of rotavirus in a children hospital of Bangladesh; thereby endorsing a logical search for an appropriate rotavirus vaccine. This cross sectional study was carried out in the Institute of Child and Mother Health, Matuail, Dhaka, Bangladesh during 2006-2007. Children aged between one month and five years suffering form diarrhea were enrolled in the study. Stool samples were analyzed by ELISA for rotavirus antigen. The rotavirus-positive samples were further analyzed for genotype determination. Among 656 stool samples, 39.5% samples were positive for rotavirus antigen. The mean age of the children studied was 12±9.9 months; the peak being in the second half of infancy. G2 was identified as the most dominant genotype (45.5%) followed by G1 (24.8%), G12 (9.6%), G9 (8.5%) and G4 (2.1%) genotypes. Since G2 were found to be the predominant circulating rotavirus strain in this study and some other studies in Bangladesh, the recommended vaccine for prevention of rotavirus infection in Bangladesh should cover this strain to have maximum effectiveness.

    Traditional Direct laryngoscope (DL) has been used by anesthesiologist during intubation for general anesthesia patients for more than a century. Video laryngoscope (VL) helps in better visualization of laryngeal orifice during intubation and reduces intubation time. This was a cross sectional study conducted in two Asian Hospitals Queen Elizabeth II hospital of Kotakinabalu, Malaysia and King Faisal Hospital Taif of Saudi Arabia to assess the first-pass success of video laryngoscope and to compare with direct laryngoscope from July 2015 to December 2017. Random lottery technique was applied for sampling. Participants of both groups (VL and DL) were enrolled by simple lottery method. Total 146 patients were enrolled with a set inclusion criterion. Mallampati class, mouth opening, thyromental distance and mobility of atlantooccipital junction were set as predictors of first-pass success. The first-pass success was 98.7% in mallampati II patients and 92.8% in mallampati III patients. Average success rate was 95.75%. The mean success rate of VL and DL was compared and was found VL had a significantly better first-pass success rate than DL (p<0.05).

    Mitral stenosis (MS) affects left atrial (LA) function as a result of hemodynamic and myocardial factors that causes significant symptoms and complications. Conventional echocardiographic methods have been practicing to see the improvement of left atrial function after successful percutaneous mitral balloon valvuloplasty (PMBV). Introduction of tissue doppler imaging allows direct and non-invasive measurement of myocardial velocities. The aim of the study was to evaluate LA functions after PMBV using colour tissue doppler imaging. This cross sectional study was performed in Cardiology department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from March 2014 to February 2015. Forty six (46) patients (28 females, mean age: 28.96±5.78 years) presenting with mitral valve stenosis who fulfilled the indications for PMBV were included in the study. Within 24 hours before PMBV, all the patients underwent colour tissue doppler study in addition to routine conventional echocardiographic examinations. Late diastolic velocities (A') measured at the septal and lateral annuli were recorded. All the measurements were repeated 24 hours after PMBV. The PMBV was done using the Inoue technique. After PMBV mitral valve areas (MVA) were significantly increased. Maximum and mean gradients, LA diameter, LA area, LA volume, systolic pulmonary arterial pressure and mean LA pressures were decreased while septal and lateral A' were significantly (p<0.001) increased. Lateral and septal A' velocities were correlated with MVA and inversely related to LA pressure measured invasively during PMBV. Tissue doppler velocities illustrated improvement of left atrial systolic function after PMBV in relation to decreased mean left atrial pressure and increased mitral valve area. Therefore, tissue doppler Imaging is a useful tool to detect improvement of left atrial systolic function after PMBV in patients with mitral stenosis.

    Hepatocellular carcinoma (HCC) is an important reason of liver-related death globally. HCC is the fifth most common cancer, the third most common cause for cancer related death in the world and responsible for approximately one million deaths each year. The incidence of HCC is expected to increase in the next two decades, largely due to hepatitis C infection and secondary cirrhosis. We have reported a case of hepatocellular carcinoma in a 56-year-old man with peritoneal metastasis. Diagnostic imaging (Ultra sonogram & CT-Scan) shown: a large hypo density, irregular outline lesion noted in right lower liver, post contrast image shown patchy enhancement of the lesion. His serum Alpha-Feto Protein (AFP) level was very high with elevated serum alanine amino transaminase (ALT) enzyme and prothrombin time. Histopathological (microscopic) features are compatible with Hepatocellular carcinoma. His Hepatitis C viral DNA load e.g., core protein variants and genotype 1, have been reported. The patient was treated by surgical resection followed by conservative treatment includes sorafenib & interferon alpha. This case report aims to outlines the epidemiology of HCC in chronic HCV, risk factors and pathophysiology that contribute to this disease process, related pathophysiology of patient's clinical features, screening recommendations, and the available statistics on the impact of new direct-acting antiviral treatment on the development on HCC.

    Approximately 80% ovarian tumors are benign, and these arise mostly in young adult females. Malignant tumors are more prevalent in ageing women, between the ages of 45-65 years. Mucinous ovarian cancer represents about 5% of epithelial ovarian cancers (EOC). We have reported a case of mucinous cystadenocarcinoma in 35-year-old lady with metastasis to momentum. Imaging (Radiograph & CT scan) studies showed a large right sided pelvic mass with probable origin in the right ovary. Cancer antigen-125 was elevated, while carcinoembrionic antigen and alpha-fetoprotein were normal. Mutational profiles shown distinct finding, as KRAS mutations positive nevertheless p53 and BRCA mutations are absent. She had undergone total abdominal hysterectomy with bilateral salphingo-oopherectomy along with pelvic dissection for removal of lymph nodes at the age of 35. She was given 3 cycles of chemotherapy with cisplatin and paclitaxel. To the best of our knowledge, this is the one of the little cases of ovarian mucinous cystadenocarcinoma being reported at a relatively young age and the first case being reported from Bangladesh.

    Hepatitis and AIDS are major public health problem globally. The aim of this study was to determine the sero-prevalence of hepatitis B, C virus and HIV infection among Bangladeshi overseas job seekers. This cross sectional study was carried out in the Department of Microbiology of Dhaka Medical College, Dhaka, Bangladesh from February 2013 to August 2013. A total of 2254 adult (18-45 years) male job seekers to Malaysia attending for health check up were enrolled. HBsAg, Anti-HCV, Anti-HIV were detected from venous blood by ELISA method using commercial kits. From the positive people, further history and information were collected by predesigned questionnaire. Prevalence of HBV was 2.35%, HCV was 0.13% and none was found positive for HIV. Prevalence of hepatitis was higher in the age group of 21-30 year and infection was more prevalent in married group. No significant relationship was found between hepatitis infection and religion, localities, profession. Only a few cases had history of possible major known route of transmission of virus. But most of them had history of taking injection or sharing blades in barber shop and history of circumcision. About 96% population had no history of hepatitis B vaccination. None was co-infected with HBV and HCV. Prevalence of hepatitis B virus infection in adult population appears to be on decline and hepatitis C and HIV infection is still low in Bangladesh. In majority of the positive person, routes of transmission of viruses were not well established.

    Increasing age is the main risk factor for chronic illnesses. The illnesses are not only physical, but also affect their psychological well-being and this has a significant effect on their quality of life. Numerous researches have shown that there is high prevalence of psychological distress in different medical and surgical patients while considerable percentage that is not detected by doctors. The study was conducted to identify the prevalence and risk factors of psychological distress in older people seeking health care at hospital in Dhaka city. This was a cross-sectional study conducted in the Bangladesh Association for the Aged and Institution of Geriatric Medicine (Bangladesh Probin Hospital) in Dhaka city, Bangladesh. A total of 451 older people seeking for healthcare was interviewed face-to-face using a standard Bengali validated General Health Care Questionnaire-12 (GHQ-12). Recruitment of respondents was based on the systematic random sampling of the older people aged at or more than 60 years who were seeking health care at hospital in Dhaka city. A total of 59.65% (n=269) participants were found to have psychological distress. Age of more than 75, education up to secondary level, being unemployment, living alone, respondents with lower socioeconomic background, not having spouse, history of bereavement was found to be significantly associated with psychological distress. Other factors such as smokers, respondents who consume alcohol, physically inactive older people, older people with multiple comorbidities and having diagnosed with a disease more than 6 months were found to be associated with psychological distress. Majority of the older patients with physical illness were distressed. The prevalence of psychological distress among older peoples seeking for healthcare with multiple comorbidities who seek care in the hospital was very high (59.65%). Age, education, marital status, history of bereavement, smoking, alcohol use, physical activity and presence of multiple comorbidities were independent determinants of psychological distress among older people seeking for healthcare. Encouraging healthy lifestyle through cessation of smoking and alcohol use and increasing physical activity could be an effective step in reducing psychological comorbidities among older people seeking for healthcare.
