Study of thyroid function in pregnancy, its feto-maternal outcome; a prospective observational study.

BACKGROUND: Pregnancy is a stress test of maternal thyroid function. The prevalence of thyroid dysfunction in pregnant women is high. Subclinical hypothyroidism occurs in 10% of all pregnancies. Effects of hypothyroidism in pregnancy are anemia, low birth weight and mental retardation in neonate. This study is aimed to evaluate maternal and fetal outcomes in pregnant women with deranged thyroid profile. The relevance of this study is to document the association of hypothyroidism and its adverse effects on mother and fetus. METHODS: This prospective observational study was carried out at R.D. Gardi Medical College, Ujjain, India. Subjects of this study were 198 antenatal women in third trimester with singleton pregnancy admitted in the obstetric ward, and informed consent was obtained. Women were chosen irrespective of age, parity, residence and socioeconomic status. Women with multiple pregnancy, a known case of thyroid disorder, or any pre-existing medical disorder were excluded. Routine hematological parameters and estimation of T3, T4 and TSH was conducted. Patients with deranged thyroid profile were subsequently assessed for maternal and fetal complications. History of infertility, family history of thyroid disease, menstrual pattern, recurrent abortion, hemoglobin level and fetal outcome were the main study variables. Data was analysed in SPSS software for statistical co-relation. RESULTS: Prevalence of thyroid disorder is 11%; with subclinical hypothyroidism, overt hypothyroidism and subclinical hyperthyroidism occurring in 5.6, 3.5 and 1.5% of subjects respectively. In women with subclinical and overt hypothyroidism, anemia was present in 26.3% being significantly associated with hypothyroidism (p = 0.008). With respect to fetal outcome, LBW 31.6% (p = 0.001), NICU admission 42.1%, (p = 0.000) and low APGAR Score (21.1%, p = 0.042) were statistically associated with hypothyroidism. Risk of anemia, Low Birth weight, NICU admissions, and low APGAR score was 4.8, 6.3, 0.14 and 3.64 times higher respectively in women with hypothyroidism than in women who are euthyroid. CONCLUSION: Prevalence of subclinical hypothyroidism is 5.6% in 3rd trimester of pregnancy. Anemia, pre-eclampsia, high caesarean rates and neonatal morbidities is significantly associated with hypothyroidism.

Peptic Ulcer Disease in Bangladesh: A Multi-centre Study.

The incidence of peptic ulcer has steadily declined through out the world. This decreasing trend is also noticeable in this subcontinent. The point prevalence of peptic ulcer (PUD) in Bangladesh was around 15% in eighties. The aim of this study was to see the present prevalence of peptic ulcer at endoscopy and to identify changing trends in the occurrence of peptic ulcer in Bangladesh. This retrospective analysis of the endoscopic records of multiple tertiary referral centres of Dhaka city were done from January 2012 to July 2013. A total of 5608 subjects were the study samples. We included those patients having peptic ulcer in the form of duodenal ulcer, benign gastric ulcer including pre-pyloric ulcer and gastric outlet obstruction due to peptic ulcer. Duodenal ulcer and benign gastric ulcer were found in 415(7.4%) and 184(3.28%) patients respectively and gastric outlet obstruction due to peptic ulcer was found in 23(0.40%) patients.

Pattern of Changes in the Findings among the Patients Undergoing Diagnostic Esophagogastroduodenoscopy in Bangladesh.

This cross-sectional observational study was conducted in the Department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University, Sir Salimullah Medical College and Mitford Hospital, Holy family Red Crescent Medical College and Hospital and Popular Diagnostic Centre, Shantinagar branch, Dhaka, Bangladesh from January 2012 to July 2013. Study subjects were included in the study irrespective of age and sex having different upper GI tract. Complaints like dysphagia, heart burn, abdominal pain/dyspepsia, nausea, vomiting, haematemesis and/or malena, anorexia, unexplained anemia, weight loss etc. All the findings of oesophagus, stomach and duodenal lesions were observed and data were recorded. The results were considered positive based on the macroscopic appearance using standard diagnostic criteria. During the study period endoscopy was performed in 5608 subjects. Among which 2968(52.92%) were male and 2640(47.07%) were female. The patients age range from 7 years to 108 years. The majority of the patients were from 40-50 years. Normal findings were observed among 3321(59.21%) cases. Gastroduodenal erosions were present among 684(12.19%) cases, Oesophageal varices in 444(7.91%) cases, duodenal ulcer diseases in 415(7.40%) cases and gastric ulcer in 184(3.28%) cases. Ca stomach was found among 165(2.94%) cases. A number of diseases were identified through this procedure. Current study observed a large proportion of patients (40.79%) had positive upper GI endoscopy.

Genotypes of hepatitis C virus infection in Bangladeshi population.

Hepatitis C virus (HCV) is a leading cause of chronic liver disease worldwide also in Bangladesh. Prevalence of Hepatitis C virus infection in rural adult population of Bangladesh is reported to be 0.6% but the exact pattern of existing genotype has not been well studied. Genotyping of HCV is important for the planning of treatment duration and predicting the response to treatment in HCV infection. This study was done to identify the existing HCV genotypes in the diagnosed cases of chronic hepatitis C infection in Bangladesh. This study was a prospective as well as retrospective cross-sectional observational study done in the department of Gastroenterology of Bangabandhu Sheikh Mujib Medical University, Dhaka Bangladesh. Cases were also taken from department of Hepatology of Bangabandhu Sheikh Mujib Medical University and Square General Hospital, Dhaka. The study was from January 2010 to March 2011. In total, 417 patients having chronic HCV confirmed by positive anti-HCV and HCV-RNA tests attending to above mentioned institutions were included in this study. Out of the 417 study subjects, 303 were males (72.66%) and 114 (27.34%) were females between 05 to 78 years of age. Most cases were in the age group 30-50 years (57.06%). The study showed that 209 (50.19%) were infected with Genotype 3. Next common identified genotype of HCV was a combination of type 3 & 4, which accounted for 120 (28.77%) and genotype -1 represented 59 (14.14%) of the cases. Other less common identified genotypes were 2, 4, 5 and mixed genotypes -1 & 3, 5 & 6 and 2 & 3; the figure being 12(2.87%), 8(1.91%), 1(0.23%), 5(1.19%), 2(0.47%) and 1(0.23%) respectively. Several subtypes were also found. Genotype 3 was the commonest HCV genotype among the Bangladeshi population. Different HCV genotypes will give a good idea regarding the plan of treatment and possible response rate as well as prognosis of HCV infection in Bangladesh. This study had some limitation like relatively smaller sample size and shorter period for the study. Further studies over a larger population are needed to draw any conclusive opinion.

Efficacy of adefovir dipivoxil therapy in patients with chronic hepatitis B viral infection.

Hepatitis B virus (HBV) infection is a major public health problem in the world. About 30% of world population has serological evidence of HBV infection. The prevalence of chronic hepatitis B in Bangladesh is reported to be 7.8%. Several potentially effective agents with different mechanisms of action have entered clinical practice and adefovir dipivoxil is one of them. Studies on the efficacy of adefovir dipivoxil in Bangladeshi patients are lacking. This was a prospective study to find out the effect of one year adefovir therapy in patients with chronic hepatitis B virus infection who were HBeAg positive. Total number of patients included in this study was 68. Among them 53(77.94%) patients continued the therapy and completed follow up. At the end of one year of therapy, intention to treat analysis showed that the rate of response (HBeAg seroconversion and HBV DNA negative) was 37.73% which was comparable to the results obtained in other studies. There was major difference in the pre treatment serum ALT level between the responders and non-responders. Comparison of reduction of serum ALT level before treatment and after treatment showed that ALT level to be lower in both responder group and non responder group. Adefovir was effective in replicative HBV infection in Bangladeshi population. So we suggest that treatment can be started and subsequent follow up can be done in chronic HBV patients who are HBeAg positive without liver biopsy.

Disease extent and local complication of ulcerative colitis in Bangladeshi population.

Ulcerative colitis may involve anywhere from the rectum alone to the entire colon. Local complications like perforation, life threatening haemorrhage, toxic megacolon, pseudo polyps, stricture, and carcinoma of colon are seen. Patients who were diagnosed as Ulcerative Colitis in Departmental Ulcerative Colitis record book from January 1990 to June 2010 was considered as study population. Information regarding the extent of the disease and local complications were taken from earliest documented Lower GIT Endoscopy. Out of 164 patients disease extent were seen in 126(76.83%) patients and among them proctitis/proctosigmoiditis were seen in 57(45.24%) patients, left sided colitis were seen in 11(8.73%) patients, extensive/pan colitis were seen in 58(46.03%) patients. Complication were seen in 164 patients and 1(0.60%) patient had life threatening haemorrhage, 25(15.24%) patients developed pseudo polyps. There was no report of perforation, toxic megacolon, stricture or carcinoma of colon. The differences found between our study and studies from other Western and Asian countries in terms of complication rate and disease extent for were probably due to low index of suspicion, incomplete workup, or incomplete records, and influence of various environmental factors. So, further large scale prospective evaluation is suggested.

Prevalence of colorectal diseases in immunological fecal occult blood test (I-FOBT) positive patients in a tertiary care hospital in Bangladesh.

Bleeding lesion anywhere in the GI tract can cause positive reaction to Immunological Fecal Occult Blood Test (FOBT). Although any colonic lesion can cause occult lower GI bleeding, relative frequency of this lesion not known. Guaic based tests require prior preparation and dietary restriction and less sensitive and specific than IFOBT for detection of occult bleeding .IFOBT is specific for human hemoglobin and is more sensitive and specific for detection of occult bleeding from any colonic lesion. Aim of this study was to diagnose occult gastrointestinal bleeding with positive IFOBT and the prevalence of colorectal disease in IFOBT positive patients in a tertiary care hospital in Bangladesh. This was a prospective cross sectional study conducted in Department of gastroenterology in collaboration with clinical pathology, BSMMU, Dhaka during the period of January 2009 to December 2009. In this study 200 patients meeting the inclusion criteria were included. Detailed clinical history and physical findings were recorded; FOBT was done on single stool specimen. Positive occult bleeding was confirmed in 90 patients of whom 80 patients underwent colonoscopy. The mean age of study population was 36.73±13.64 (range 16 to 72) years. At colonoscopy lesion were identified in 46(57.50%) patients, of which colonic polyp in12 (15%), colorectal cancer in 11(13.7%), inflammatory bowel disease in 3(3.75%), hemorrhoids and anal fissure in 7(8.75%), tuberculosis in 5(6.25%), and proctitis in 1(1.25%) cases. A positive IFOBT is more sensitive and specific test than other FOBT for detection of occult lower GI bleeding of colonic origin. In this study colorectal diseases were detected in 57.50% of the IFOBT positive patients, so IOBT can be used as an important diagnostic tool for detection of occult lower GI bleeding.

Efficacy of Probiotics as Adjuvant to the Standard Triple Therapy for the Treatment of Helicobacter Pylori-Associated Peptic Ulcer Disease: A Randomized-Control Trial.

Helicobacter pylori (H. pylori) is a major cause of peptic ulcer disease (PUD), which needs effective eradication of the organism to heal ulcers and prevent a recurrence. In recent years, increasing resistance of H. pylori to clarithromycin and amoxicillin have decreased peptic ulcer cure rate following treatment with standard triple therapy worldwide. The addition of probiotics with standard triple therapy has shown excellent efficacy in H. pylori eradication and has appeared to be an alternative treatment strategy. This study aimed to assess the efficacy of standard triple therapy plus probiotics for H. pylori eradication and ulcer healing compared to standard triple therapy alone. This double-blind, randomized placebo-controlled clinical trial included 158 with endoscopically proven H. pylori-positive PUD who were randomly allocated equally into two groups; Group A was treated with standard triple therapy plus probiotics, and Group B was treated with standard triple therapy plus placebo for 14 days. The outcome was evaluated at the end of treatment (14th day) (symptoms plus adverse events) and after 60 days of treatment completion (H. pylori eradication and ulcer healing). One hundred forty four (144) study subjects (73 in Group A and 71 in Group B) completed the study. Significantly higher H. pylori eradication rate (82.2%vs. 67.6%, p=0.043) and ulcer healing rate (92.3% vs. 60.0%, p=0.049) were observed in the standard triple therapy plus probiotic group than the standard triple therapy plus placebo group. Early relief of epigastric pain was also seen among patients getting probiotics than the placebo in addition to standard triple therapy (42.3% vs. 15.1%, p<0.001).The addition of probiotics significantly improves the H. pylori eradication rate and ulcer healing rate among the patients getting standard triple therapy. Further large-scale, multi-center studies are needed to recommend routine use of probiotics with standard triple therapy for H. pylori eradication.

Demographic and Clinical Characteristics of Functional Dyspepsia and Its Subtypes in Adult Patients: An Experience from a Tertiary Care Centre in Bangladesh.

Functional dyspepsia (FD) is a common gastrointestinal problem in the world. The Rome III consensus subdivided functional dyspepsia into two groups: meal-related postprandial distress syndrome (PDS) and meal-unrelated epigastric pain syndrome (EPS). Limited data are available regarding FD in Bangladesh. The aim of this study was to investigate the demographic and clinical characteristics of FD and its sub-types. This cross-sectional study was conducted in which we recruited patients who attended the outpatient department of Gastroenterology of Bangabandhu Sheikh Mujib Medical University, Bangladesh from March 2017 to February 2018. Patients fulfilling Rome III FD criteria and a negative upper GIT endoscopy were included for this study. The patients were then subdivided into 'pure' PDS (i.e. meeting criteria for PDS without EPS symptoms), 'pure' EPS (i.e., meeting criteria for EPS without PDS symptoms), and overlapping PDS-EPS (i.e., symptoms of both PDS and EPS) groups. Total of 368 FD patients (56.0% females, mean age 32.8±8.6 years, BMI: 22.0±2.7), were included in this study. Out of them, 112(30.4%) patients (57.2% females, mean age 33.9±9.3 years, BMI: 22.0±2.7) fulfilled criteria of pure EPS and 64(17.4%) patients (68.8% females, mean age 33.2±7.8 years, BMI: 22.1±2.4) fulfilled criteria of pure PDS. However, the majority of patients [192(52.2%), 52.1% females, mean age 32.0±8.4 years, BMI: 21.9±2.8] had symptoms of overlapping EPS-PDS. More than 40% of patients in our study presented with 3 or more of the four key symptoms of FD. A longer duration of presenting symptoms was seen among patients with overlapping EPS-PDS in comparison to pure EPS and pure PDS (p<0.001). A significant overlap of symptoms of both EPS and PDS was noticed among patients with FD. The value of dividing functional dyspepsia into the subgroups of PDS and EPS is thus questionable. Further research and modification of the diagnostic criteria for FD subtypes are necessary.

Efficacy of Peppermint oil in diarrhea predominant IBS - a double blind randomized placebo - controlled study.

Irritable bowel syndrome (IBS) is one of the most common functional gastrointestinal disorder which is associated with considerable sufferings of patient and Peppermint oil is volatile oil, its active principle is menthol-contain a cyclic monoterpine which has anti-spasmotic properties due to its ability to block calcium channel of intestinal smooth muscles. This study observed the efficacy of peppermint oil for relieving the symptoms and changes of quality of life (QOL) in diarrhea predominant IBS. This was a prospective double blind randomized placebo-controlled study conducted in the Bangabandhu Sheikh Mujib Medical University during July 2008 to September 2009. Patients who fulfilled ROME II were initially selected but those had red flag signs or any organic disease was excluded from the study. Seventy four patients were enrolled in the study and randomly allocated to receive either peppermint oil or placebo three times daily for six weeks. Changes of symptoms were assessed three week interval during treatment and two weeks after the end of treatment. Data were analyzed by paired and unpaired 't' test. Finally sixty five patients completed the trial. It was observed that, at six weeks of therapy abdominal pain is markedly improved (mean±SD) 4.94±1.30 in peppermint oil group compared with 6.15±1.24 in placebo group and the difference was statistically highly significant (p>0.001). But two weeks after end of trials pain score again increased (6.09±1.93). Other symptoms and quality of life did not improve significantly. So the study result concludes that peppermint oil is effective in reliving only abdominal pain in diarrhea predominant IBS transiently.

A facile and green synthesis of Mn and P functionalized graphitic carbon nitride nanosheets for spintronics devices and enhanced photocatalytic performance under visible-light.

Manganese and phosphorus co-doped, graphitic carbon nitride (g-C3N4) nanosheet (Mn/P-g-C3N4) is prepared by facile and green calcination process of melamine (C3H6N6), manganese chloride tetrahydrate (MnCl2·4H2O), and ammonium dihydrogen phosphate ((NH4)H2PO4). The Mn/P co-doping significantly enhances magnetic values compared to pristine-g-C3N4, phosphorus-doped g-C3N4 (P-g-C3N4), and manganese-doped g-C3N4 (Mn-g-C3N4). We find that Mn/P-g-C3N4 is a half-metallic ferromagnetic material having a magnetic moment and Curie temperature of 4.51 µB and âˆ¼ 800 K, respectively. The ultraviolet-visible (UV-vis) absorption spectrum of Mn/P-g-C3N4 reveals superior absorption in broader wavelength compared to pristine-g-C3N4, P-g-C3N4, and Mn-g-C3N4. The methyl orange degradation efficiency of Mn/P-g-C3N4 photocatalyst is 94 %, which is three times more than that of pristine-g-C3N4 (29 %) and more significant than the P-g-C3N4 (46 %) and Mn-g-C3N4 (58 %). Furthermore, density functional theory (DFT) calculation explains the origin of high magnetic behavior, the boosted photocatalytic efficiency of Mn/P-g-C3N4, and the essential material properties like structure, bandgap, the density of states (DOS), and atomic level interaction. This work may be helpful for reasonably designing ferromagnetic material for spintronics devices and boosting visible-light (VL) photocatalytic performance for environmental remediation.

Early surgical intervention for nasal deformity in Binder's syndrome.

OBJECTIVE: To assess benefits of surgical intervention at an early age and focus on surgical techniques using exclusively autologous cartilage grafts. METHODS: Five children aged 8-15 years, treated between March 2016 and 2020, underwent augmentation rhinoplasty using autologous cartilage, with post-operative follow up ranging from 1.5 to 2 years. Photographs and Rhinoplasty Outcome Evaluation questionnaire scores were examined. RESULTS: Augmentation was achieved without complications. No restricted skin or mucosal pockets were encountered. Patients showed improved confidence and perspective with regard to self-image, and were less socially self-conscious. There was significant improvement in all Rhinoplasty Outcome Evaluation questionnaire scores. CONCLUSION: Early surgery allows augmentation with easier release of skin and mucosal pockets, and without the tension otherwise encountered if primary augmentation is performed at a later age. It offers a chance to improve confidence and self-perception in a growing child conscious about their appearance, which may make them socially withdrawn. Autologous cartilage gives better results than bone grafts, and is comparable with silicone but without its complications.

Engineering generalized synchronization in chaotic oscillators.

We report a method of engineering generalized synchronization (GS) in chaotic oscillators using an open-plus-closed-loop coupling strategy. The coupling is defined in terms of a transformation matrix that maps a chaotic driver onto a response oscillator where the elements of the matrix can be arbitrarily chosen, and thereby allows a precise control of the GS state. We elaborate the scheme with several examples of transformation matrices. The elements of the transformation matrix are chosen as constants, time varying function, state variables of the driver, and state variables of another chaotic oscillator. Numerical results of GS in mismatched Rössler oscillators as well as nonidentical oscillators such as Rössler and Chen oscillators are presented.

To compare the efficacy of triple therapy with furazolidone, amoxicillin and omeprazole for two weeks and three weeks in the eradication of Helicobacter pylori in Bangladeshi duodenal ulcer patients.

Helicobacter pylori eradication is the mainstay in the treatment of Helicobacter pylori associated peptic ulcer disease. Furazolidone was tried in several developing countries and showed good results in some trials. Increasing the duration of treatment has been shown to improve the eradication rate. This study was done to compare the efficacy of triple therapy for two weeks (Group-A) and three weeks (Group-B) consisting of omeprazole 20 mg b.d. amoxicillin 1 gm b.d. and furazolidone 200 mg b.d. in the eradication of Helicobacter pylori in duodenal ulcer patient. A total of 70 duodenal ulcer patients with Helicobacter pylori infection were included in the study. Healing of duodenal ulcer was assessed three months after the end of treatment and at the same time Helicobacter pylori eradication assessed by Campylobacter Like Organism (CLO) test and histology. In group-A, duodenal ulcer was healed in 17 (58.62%) patients and Helicobacter pylori was eradicated in 15 (52%) patients. In group-B, duodenal ulcer was healed in 19 (61.30%) patients and Helicobacter pylori was eradicated in 18 (58%) patients. Healing of duodenal ulcer was not significantly different between two groups. Eradication of Helicobacter pylori was also not significantly different between two groups.

Histopathological alterations in post-infectious irritable bowel syndrome in Bangladeshi population.

Irritable bowel syndrome (IBS) is the most common gastrointestinal disorder encountered in general practice. Although enormous progress in the pathogenesis of IBS has been made, it is still poorly understood. A significant proportion of patients with IBS, report onset of symptoms following an episode of acute gastroenteritis. Aim of the study was to determine whether post infective irritable bowel syndrome (PI-IBS) has histological or clinical features that are distinct from those of IBS patients with no history of preceding infection. A total of 50 consecutive IBS out patients and 10 healthy control subjects completed a questionnaire detailing symptoms, mode of onset, and previous psychiatry history. All underwent a full diagnostic workup including colonic biopsy and histopathology. Patients were divided according to onset of symptoms into post infectious IBS (PI-IBS, N=18) and non-post infectious IBS (non-PI-IBS, N=32) patients. Diarrhea predominantly occurred more frequently in PI- IBS (70%) than in non-PI-IBS (40%) patients (p<0.05). Histopathological examination of the biopsy specimen from the sigmoid colon of the observed individuals showed a significant increase in the number of chronic inflammatory cells in both groups of IBS patients comparing to the control group (p<0.001). Lymphoid follicles were increased in both groups of IBS patients in comparison to control group (p<0.05). Mast cells were increased in IBS patients comparing to the control group (p<0.05) and it was significantly increased in the PI-IBS patients than the non-PI-IBS patients (p<0.001). Individuals with PI-IBS are clinically distinct subgroup characterized by predominant diarrheal symptoms and increased mast cells compared to those with non PI-IBS.

Variable stiffness colonoscope versus regular adult colonoscope: meta-analysis of randomized controlled trials.

BACKGROUND AND STUDY AIMS: The variable stiffness colonoscope (VSC) may have theoretical advantages over standard adult colonoscopes (SACs), though data are conflicting. We conducted a meta-analysis to compare the efficacies of the VSC and SAC. STUDY DESIGN: We searched Medline (1966 - 2008) and abstracts of gastroenterology scientific meetings in the 5 years to February 2008, only for randomized clinical trials (RCTs) of adult patients. Trial quality was assessed using the Delphi list. In a meta-analysis with a fixed effects model, cecal intubation rates, cecal intubation times, abdominal pain scores, sedation used, and use of ancillary maneuvers, were compared in separate analyses, using weighted mean differences (WMDs), standardized mean differences (SMDs), or odds ratios (ORs). RESULTS: Seven RCTs satisfied the inclusion criteria (1923 patients), four comparing VSC with SAC procedures in adults, and three evaluating the pediatric VSC. There was no significant heterogeneity among the studies. The overall trial quality was adequate. Cecal intubation rate was higher with the use of VSC (OR = 2.08, 95 % confidence interval [CI] 1.29 to 3.36). The VSC was associated with lower abdominal pain scores and a decreased need for sedation during colonoscopy. Cecal intubation time was similar for the two colonscope types (WMD = - 0.21 minutes, 95 % CI - 0.85 to 0.43). Because of the nature of the intervention no studies were blinded. There was no universal method for using the VSC. CONCLUSIONS: Compared with the SAC, VSC use was associated with a higher cecal intubation rate, less abdominal pain, and decreased need for sedation. However, cecal intubation times were similar for the two colonoscope types.

Evaluation of Duodenal Eosinophil Count in Adult Patients with Functional Dyspepsia.

Several mechanisms have been proposed to explain the symptoms of functional dyspepsia but actual pathogenesis is still poorly understood. Recent studies support duodenal abnormality to be the most important causal link to explain symptoms and to understand abnormal pathophysiology of functional dyspepsia. The aim of this prospective observational study is to compare eosinophil count in duodenal mucosa between patients with functional dyspepsia and control subjects without dyspepsia and was done at the department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from December 2015 to December 2016. Total 42 patients of functional dyspepsia based on Bangla validated version of ROME III criteria and 42 controls who were referred for upper gastrointestinal endoscopy for reasons other than dyspepsia were included. Biopsy specimens were collected from the second part (D2) of the duodenum of all participants. Eosinophil count was quantitatively evaluated by hematoxylin and eosin staining and expressed in numbers per 5 HPF. Significantly increased duodenal eosinophil count was found in functional dyspepsia group than non dyspeptic patients (22.78±08.78 vs. 14.90±10.70, p=0.001). Higher duodenal eosinophil count was found in patients with postprandial distress syndrome. Increased duodenal eosinophil count was found in patient of functional dyspepsia. It requires further large scale multicenter studies to establish duodenal eosinophilia as a biomarker of functional dyspepsia.

Bimatoprost in Dermatology.

Bimatoprost is a prostamide analogue used for treatment of glaucoma in ophthalmology. Surprisingly, the side effects such as increased pigmentation of eyelids and hypertrichosis in patients being treated with prostaglandin analogues for glaucoma have opened new areas of application in various dermatological disorders such as alopecia mainly affecting eyelashes, eyebrows, and vitiligo.

Dermoscopy of alopecia areata-a retrospective analysis.

BACKGROUND: Dermoscopy devices can overcome the refractive properties of stratum corneum by interface medium or cross polarization such that the lesion can be easily seen. AIM: To examine the dermoscopic feature in alopecia areata and correlate the severity of disease with dermoscopic features. MATERIALS AND METHODS: Retrospective analysis of 72 patients suffering from alopecia areata (AA), irrespective of age and sex, who visited the dermatology outpatient department of a tertiary care center in Eastern India was carried out. The most recently developed cases of AA were examined dermoscopically. Variables included yellow dots (YDs), black dots (BDs), broken hair (BH), short vellus hair (SVH), and exclamation mark hair (EMH) on the basis of available literature and expertise. RESULTS: Yellow dots was the most common finding seen in 57 cases (79.16%), black dots in 51 cases (70.8%). Short vellus hair was seen in 32 cases (44.44%), broken hair was seen in 31 cases (43.05%), and exclamation mark hair in 23 cases (31.9%). YDs per field of vision was considered as the most common finding with increased severity of AA. CONCLUSION: YDS, in increased number per field of vision, is the most consistent finding seen in severe cases of AA, as they are in progressive AA and alopecia universalis. An increased number of SVH and terminal hairs were seen in patients who were being treated.

Effects of dietary tamarind on cholesterol metabolism in laying hens.

An experiment was conducted to evaluate the potential for dietary tamarind to alter serum and egg yolk cholesterol concentrations and overall performance in different layer strains. Thirty, 43-wk-old, Hisex Brown, ISA Brown, Lohmann Brown, Starcross Brown, Babcock B-300, and Starcross-579 strains (5 hens per strain) were fed diets supplemented with 0 (control), 2, 4, 6, or 8% oven-dried tamarind for 6 wk. Egg production, egg mass, and efficiency of feed utilization followed a quadratic response with a maximum when the diet contained 2% tamarind and a minimum when 8% tamarind was fed (P < 0.05). There were no differences (P > 0.05) among strains for egg production, egg weight, yolk weight, egg mass, feed consumption, or feed efficiency. Yolk weight increased linearly (P < 0.05) with increasing levels of dietary tamarind in wk 1, 2, and 3 as well as when averaged over 6 wk. Egg yolk cholesterol concentrations were not affected by dietary tamarind. Serum cholesterol concentrations, however, decreased quadratically with increasing levels of dietary tamarind (P < 0.05). It was concluded that 2% supplemental dietary tamarind could decrease serum cholesterol concentrations and increase layer performance.
