Abstract
Non-invasive tools are needed to rule out the presence of esophageal varices (EV) in patients with chronic liver disease. The aim of this study was to evaluate diagnostic accuracy of Liver stiffness-spleen size-to-platelet ratio (LSPS) for EV detection and identification of high risk EV in patients with CLD. A total of 70 patients with CLD irrespective of the etiology attending at OPD and admitted in Department of Gastrointestinal, Hepatobiliary and Pancreatic Disorders (GHPD) of BIRDEM General Hospital, Dhaka, Bangladesh from January 2016 to October 2017 were enrolled in this observational cross-sectional study. All patients underwent routine laboratory tests, liver function tests, ultrasonography, liver stiffness (LS) measurement and esophagogastroduodenoscopy. Clinical value of LSPS was compared with platelet count, spleen size and LS for detection of esophageal varices. Diagnostic accuracy was assessed by the Area under the receiver operating characteristic (AUROC) curve. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated using ROC curve. LSPS has better diagnostic accuracy for detection of EV in terms of AUROC, showing superiority over each factor alone. LSPS also detect high risk EV but accuracy was lower than detection of EV. The optimal cutoff values of LSPS for EV and high risk EV were 0.879 and 4.132 respectively, at which AUROC, negative predictive value, and accuracy were 0.910 [95% confidence interval (CI) 0.832-0.988], 90.9% and 90.0% and 0.695 (95% CI 0.520-0.870), 62.5% and 69.4% respectively. LSPS represents a useful, noninvasive method to detect EV and a high risk EV in patients with CLD. Clinicians should recommend those patients with CLD who show higher values of LSPS to undergo further endoscopic examination.

Abstract
Staphylococcus aureus is a common causative agent of bovine mastitis in dairy herds worldwide. This study was designed to assess the prevalence of mastitis in cows through screening tests and molecular characterization of Staphylococcus aureus strains. Out of 175 randomly screened cows, mastitis was detected in 50 cows by California Mastitis Test (CMT), and from those mastitic cows, 200 quarter milk samples were collected for subsequent culture and PCR based identification. The herd, cow and quarter level prevalence of mastitis was 73.3, 28.6 and 29.5% respectively, and subclinical mastitis (SCM) was the predominant type in all cases. According to bacteriology the overall prevalence of herd, cow and quarter level Staphylococcus aureus mastitis was 72.7, 74.0 and 62.0%, respectively, and the pathogen was mostly associated with clinical mastitis (CM). Cows breed, parity, daily milk yield, regular teat dipping, and dry cow therapy were significantly associated (P < 0.05) risk factors for mastitis onset. This study identifies 145 Staphylococcus aureus isolates which varied greatly with the categories of mastitis (higher in CM), udder quarter location (highest in right rear quarters), and to a lesser extent in the study areas (P < 0.05). Antimicrobial susceptibility testing revealed that 79.3% Staphylococcus aureus strains were resistant to at least one antimicrobial, 49.0% to two or more antimicrobials, and clinical isolates showed more resistance to all tested antibiotics. The highest resistance rate was found to oxytetracyclin, and no resistance to ceftriaxone and azithromycin. Seven enterotoxin gene profile were detected in the tested isolates, and mecA was found in 20.0% isolates indicating the emergence and spread of methicillin-resistant Staphylococcus aureus (MRSA). The isolates were carrying genes in combination, and were found higher in SCM cases. In this study, plasmids (>23 kb to 2.9 kb) were detected in 70.3% strains, and 54.9% plasmid bearing strains were multiple drug resistant (MDR). Thus, the high prevalence of Staphylococcus aureus mastitis is an important concern for diary industry of Bangladesh since the strains of this pathogen is becoming more resistant to commercially available antimicrobials, and this is an alarming concern for both animal and public health.

Abstract
Administration of vitamin, mineral and antimicrobials at the end of lactation plays potential role in preventing mastitis in dairy cows. A total of 255 cows dividing into five groups (A = 50, B = 50, C = 50, D = 50 and E = 55) at their late gestation period were selected to explore the effect of vitamin E, selenium and antimicrobial therapy on mastitis incidence, their productive and reproductive performances. Each cow of group A received α-tocopherol + sodium selenite orally daily for last 30 days before calving, while each cow of group B, C and D was treated with α-tocopherol + sodium selenite intramuscular injection, procaine penicillin + neomycin sulfate, and dicloxacillin sodium intramammary infusions at Day 30-20 before calving, respectively. Group E cows served as untreated control. California mastitis test (CMT) revealed that 70.0%, 76.0%, 84.0% and 100.0% cows in group A, B, C and D, respectively were free from new intramammary infections (IMIs) during early lactation period. The bacteriological results showed highest IMIs rates (76.3%) in group E and lowest IMIs (2.0%) in group D (P < 0.05). Staphylococcus aureus and Escherichia coli were the most predominant udder pathogens in all groups except group D (only CNS). The mean IMIs incidence (20.5%) was significantly lower in treated cows (P < 0.001). The treated cows had higher cure rates (81.9%) than control cows (23.1%) and overall efficacy of treatments on cure rates was 71.8% for all mastitis pathogens (P < 0.0001). The productive and reproductive performances of the treated cows at postpartum and early lactation period remained always higher than their non-treated counterparts (P < 0.001). A number of cow and herd related factors were identified to be significantly associated with mastitis (P < 0.001). The results concluded that antimicrobial therapy had more beneficial effect in preventing mastitis over vitamin-mineral administration and intramammary infusion with dicloxacillin sodium remained as the best effective preventive strategies for mastitis in dairy cows.

Adverse drug reaction to tuberculous chemotherapy is not an uncommon problem. Usually it occurs to single drug and can be treated easily with minimal intervention. We follow WHO recommended guideline for National Tuberculosis Control Programs to treat these adverse reactions. Here we found an adult who has been suffering left sided pleural tuberculosis developed anaphylactic reaction to first dose of category-1 anti-TB regime. Later on it was found that he could not even tolerate smaller challenging doses of isoniazide, Ethambutol, Rifampicin and Pyrazinamide separately. It became very difficult to choose an alternate regime for this patient. Lastly a regime with levofloxacin, streptomycin and clarithromycin was give to treat him and patient was recovered with this regime successfully. This experience will help in management of unusual drug reactions to anti-tuberculosis drugs.

Abstract
Chronic hepatitis B and C virus infection can lead to cirrhosis and hepatocellular carcinoma. Several studies investigated the diagnostic and prognostic value of some biochemical markers to detect the hepatic fibrosis and found a correlation between serum markers and hepatic fibrosis. Among them serum hyaluronic acid (HA) has been identified as a potential marker of fibrosis or cirrhosis in different studies. A prospective study in 60 subjects was conducted to evaluate the association between serum HA and hepatic fibrosis. Thirty consecutive patients with chronic HBV or HCV infection undergoing liver biopsy were studied. Sera were obtained for HA using enzyme linked protein binding assay. Patients with hepatic fibrosis had higher serum HA concentration compared with healthy subjects (236.65 ± 227.07 vs. 23.32 ± 14.22 respectively, p<0.001). Correlation was found between high serum HA concentration and increasing degree of hepatic fibrosis (R-0.322 and p<0.041). This study had shown a good correlation between serum HA and different stages of hepatic fibrosis. So serum HA may be used as a useful marker of hepatic fibrosis.

Abstract
Changes in the size, distribution and composition of the population of the United States will have significant effects on health care professionals in the coming years. For dentists and other professionals involved in health care provision, it is likely that among the effects of demographic change will be change in the characteristics of their patient base, change in the characteristics of health professionals, and potential change in the socioeconomic resources of their patients. In this article, we describe current and expected future patterns of change in the population of the United States and discuss their significance for dentistry in the twenty-first century.

Abstract
In this paper we examine the effects of socioeconomic development, the status of women, and family planning on fertility and the extent to which these effects vary among the nineteen districts of Bangladesh. The 1983 and 1991 Bangladesh Contraceptive Prevalence Survey data are used to examine the effects of these factors on differences in contraceptive use among currently married women aged 15-49. The proportion of currently married women aged 15-49 using contraception was 46.3 per cent in 1991, a considerable increase from 26.5 per cent in 1983. Contraceptive use rates for all the districts increased substantially over the period between 1983 and 1991 and the gap between Dhaka's rate and those of other districts was narrower in 1991 than in 1983. An analytical model composed of socioeconomic development, status of women, and family planning variables is tested using logistic regression. The logit model is used to evaluate the effects of a selected group of variables on the probability of using contraceptive methods. The analysis demonstrates clearly that socioeconomic development and women's status significantly impact the use of contraceptive methods in Bangladesh. The results also suggest that better-educated, employed women are more likely to use contraception than those who have little or no formal education and who are not employed. In 1983, rural-urban differences in contraceptive use were significant, but in 1991 area of residence was not significant, which suggests that family planning programs may have played an important role in providing contraceptive information and technology to rural areas. Our analysis also suggests that family planning programs operated more efficiently in some districts than in others, and regional differences remained important in 1991 as they were in 1983. Decomposition analysis suggests that shifts in population structure favored increased contraceptive use in Bangladesh. This analysis also indicates that change in rate is also important, contributing about 21 per cent of the overall increase in contraceptive use.
