Measles is a highly contagious vaccine preventable viral disease which mainly affects children. Infection with wild measles virus induces an immune response that provides life long protection. Measles has been targeted for global eradication. In Bangladesh, there is insufficient data about the antibody responses in children following measles vaccination. In the present study, the antibody response of a single dose of measles vaccine was investigated among 77 children of different age groups. The humoral immune response immunoglobin IgG (IgG) was detected by a commercial Enzyme-linked Immunosorbent Assay (ELISA). Among the study population, detectable antibody titer was observed in 75.3% children while 24.7% showed detectable titers. The mean antibody concentration was highest (2.75 ± 1.10 IU/ml) in the 13-24 months age group, decreased gradually with age, and was lowest (0.77 ± 0.13 IU/ml) in the 85-96 months age group. Thereafter, the mean antibody concentration gradually increased again in the 97-108 months (1.20 ± 0.13 IU/ml) and in the 109-120 months (1.45 ± 0.13 IU/ml) age groups. The mean antibody titer was statistically significant in relation to age (p<0.01) but not to gender (p<0.95). This study showed that around 25% children remained antibody negative indicating challenges ahead for eradication of measles from Bangladesh.Bangladesh J Med Microbiol 2016; 10 (1): 13-17

Gamma interferon (IFN-?) plays an important role in the immune response to live measles virus vaccination. To study the immune response to measles vaccination, IFN-? level was estimated in 30 children. Of these, 24 children vaccinated with a single dose of measles vaccine at nine months of age and 06 children vaccinated with a second dose during the Measles Catch-up Immunization campaign. Measles vaccine strain was cultured in Vero cell line and the Tissue Culture Infective Dose (TCID)50 was used as standard live virus. Peripheral blood Mononuclear cells (PBMCs) was separated by Ficoll- Hypaque density gradient centrifugation and stimulated with measles virus antigens and mitogens (lectin), cultured in CO2 and IFN-? level was measured from culture supernatant by ELISA. On stimulation with measles antigen and lectin respectively, IFN-? level was highest (105 pg/ml and 226.54 pg/ml) in the 109-120 months age group while it was lowest (12.97±8.16 pg/ml and 13.16±8.0 pg/ml) in the 61-72 months age group. No significant difference was observed in IFN-? level after stimulation with either measles antigen or lectin among well-nourished (p<0.8) and mal-nourished (p<0.7) children suggesting that nutritional status did not have any effect on IFN-? level. However, IFN-? level was higher in children who received two dose of measles vaccine than those who received a single dose (p<0.001).Bangladesh Med Res Counc Bull 2014; 40 (3): 118-121

Background: Whole-cell pertussis (wP) vaccine administration is still advocated for children under 7 years of age in Iran. However, there is no recommendation for the administration of a dose of tetanus, diphtheria, and acellular pertussis (Tdap) vaccine to childbearing age/pregnant women in the Iranian vaccination program and it has increased the risk of infection through waning immunity during women’s childbearing age life. The study aimed to assess the levels of anti- Bordetella pertussis antibodies in childbearing age women of different ages in Iran. Methods: A cross-sectional study was conducted on a total number of 360 childbearing age women divided into six age groups, with 5-year intervals from 15 to 45 years old, in 2018–2019. Then, the levels of immunoglobulin A (IgA), immunoglobulin M (IgM), and immunoglobulin G (IgG) antibodies against B. pertussis were evaluated using enzyme-linked immunosorbent assay (ELISA). The IBM SPSS Statistics software (version 16.0) (SPSS Inc., Chicago, IL, USA) was used for data analysis. Results: The mean age of the participants was 30.01 ± 8.35 years (range 14–45 years). All the cases were IgM negative, but two IgA-positive individuals (in the age groups of 14–19 and 30–34 years) were reported. Overall, 239 (66.4%) cases were IgG positive. The mean age of IgG-positive cases was 30.37 ± 8.37 years. The IgG-positive cases were mostly in the age groups of 30–34 and 35–39 years [43 (71.1%)]. The odds of IgG positivity were 1.97. The highest odds of IgG positivity were seen in 30–34 and 35–39 years groups (2.52) and the lowest odds were seen in the 20–24 and 25–29 years groups (1.60). Using the Jonckheere–Terpstra test, the increasing trend of IgG changes in different age groups was not statistically significant (Tπ=5.78, p = 0.09). Conclusion: The infants of women of childbearing age might be prone to pertussis in countries using the wP vaccination schedule. It is suggested to administer a dose of Tdap to women before or during pregnancy to increase the immunity of their infants against this disease during early infancy.

Abstract Background Early diagnosis and treatment of ACS can reduce the risk of complications and death. Delay calling for help can increase morbidity and mortality. It is unclear which age group among patients with acute coronary syndrome tend to delay their call for help. Results Our observational retrospective study showed that men and women in their 50s and 40s respectively tend to delay their call for help from symptoms onset. For the former, the mean time delays (590 ± 71.1 min), whereas for the latter it was (1084 ± 120.1 min). Moreover, these groups tend to have a longer time delay between symptoms onset and arrival at the hospital. Among deaths, we observed that the death rate was proportional to the time delay, which is not unexpected. Next step, we plan to perform a qualitative study in the form of questionnaires to target the individuals with a high risk of CVD within these age groups. Conclusion Middle age group of both genders tend to delay their call for help when they experience symptoms of ACS; moreover, regardless of the age, the longer the delay, the higher the mortality rate. The results of this study gave us a better understanding of our local population and will pave the road for a well-structured teaching programme for them to minimise the time delay for calling for help.

ABSTRACT: The aim of this research was to measure the intraocular pressure (IOP) of normal chinchilla eyes using the rebound tonometer. A further aim was to assess whether there were differences in the values of intraocular pressure in relation to animals age, gender and time of day. Thirty-six chinchillas were divided into three groups of 12 chinchillas each, by age: Group I (2-6-month-old), Group II (20 and 34 months) and Group III (37 and 135 months). Ophthalmic examination was performed previously by Schirmer tear test, slit lamp biomicroscopy, indirect ophthalmoscopy and fluorescein test in all chinchillas. Three measurements of intraocular pressure were assessed on the same day (7, 12 and 19h). Tonometry was performed on both eyes using the rebound tonometer after calibration in "p" mode. Statistical analysis was performed with SigmaPlot for Windows. The mean IOP for groups I, II and III were 2.47±0.581mmHg, 2.47±0.581mmHg and 2.51±0.531mmHg, respectively. No significant differences were reported between age and IOP and no significant differences were reported between the time of day and IOP. The IOP in chinchillas did not differ significantly between genders or ages of the animals, and did not change with time of day.

The purpose of the study was to determine the structure of the incidence of thymus tumors in the Kharkiv region, taking into account the histological classification of thymus tumors and to analyze diagnostically significant indicators of the immune response of patients with thymomas. Materials and methods. The medical histories of 158 patients aged 16 to 80 years with diseases of the thymus gland were studied during 2006-2019. The indices of phagocytic activity of granulocytic neutrophils in blood heparinization, phagocytic index, phagocytic number, phagocytosis completion index and activity of proteins of the complement system were analyzed. We also analyzed the indices of the number of T- and B-lymphocytes obtained using monoclonal antibodies (CD2+, CD3+, CD4+, CD8+, CD16+, CD19+) (immunofluorescence method). Results and discussion. The structure of the incidence of tumors of the thymus in the Kharkiv region was determined, taking into account the histological classification of tumors of the thymus and indicators of the immune status of patients with thymomas. The relationship was determined between the indicators of the phagocytic activity of granulocytic neutrophils and the activity of proteins of the complement system, as well as changes in the ratio of the subpopulation composition of T-lymphocytes in patients with different types of thymomas. Lymphoepithelial thymoma is most widespread in male population in the age groups 40-59 and 20-39 years, and the lymphoid thymoma – in male population in the age group 20-39 years and female population in the age group 40-59 years. The significant decrease (p <0.05) in the mean value of the phagocytic index was revealed in group of patients with lymphoid thymomas. The subpopulations of T-lymphocytes CD3+ and CD4+ were significantly reduced (p <0.05) in group of patients with lymphoepithelial thymomas. The subpopulations of T-lymphocytes CD4+ and CD8+ were significantly reduced (p <0.05) in group of patients with lymphoid thymomas. The increasing of the mean values of markers CD16+ and CD19+ (p <0.05) in all study groups indicates that the processes of antibody production in patients with thymomas are activated regardless of the type of thymoma. Conclusion. The structure of thymus pathology in the population of the Kharkiv region is characterized by the predominance of tumor pathology in the general structure of thymus pathology, which is 51.3%. The lymphoepithelial and lymphoid thymomas are the most common tumors of the thymus and were recorded in 64.2% and 30.8% of patients with thymomas, respectively

 Background: Acute appendicitis is very common surgical cause of acute abdomen and needs surgical removal either by laparoscopic or open appendicectomy. The aim of this study is to compare frequency of surgical site infection (SSI) in patients undergoing laparoscopic and open appendicectomy. Materials and Methods: The study was prospective study conducted in NMCTH, Biratnagar. Total 200 patients with diagnosis of acute appendicitis admitted through the emergency department of our hospital were included in the study. The patients were randomly allocated in two groups: Laparoscopic appendicectomy group (LA) and Open appendicectomy group (OA). Both groups underwent successful emergency appendicectomy. Wound infections in terms of surgical site infection (SSI) if present were recorded. All age groups and both sexes were included.  Results: Two hundred patients underwent appendicectomy, one hundred Laparoscopic appendicectomy (LA) and another hundred open appendicectomy (OA). The mean age of patients with acute appendicitis was 30.63±16.14 years with minimum of 6 years and maximum of 77 years. The highest number of patients were in age group of 10 to 20 years (29.5%). In LA group SSI noted in 3 patients (3%) whereas in OA group it was found in 12 patients (12%). Conclusion: Laparoscopic appendicectomy is better and offers great advantages in terms of SSI as compared to Open appendicectomy.

ABSTRACT BACKGROUND: The bacterium Helicobacter pylori is strongly associated with the development of gastric adenocarcinoma. Currently, the prevalence in developed countries is 40%, but this value increases considerably in developing countries, which can reach rates bigger than 90%. OBJECTIVE: The objective of this study was to determine the mean and annual prevalence of Helicobacter pylori infection in patients from Itajaí during the period from July 1992 to April 2016, as well as the gender and age groups most affected. METHODS: After consent of the clinical director of the Gastroclinica Itajaí and confidentiality commitment about the research, the database of the Endoscopy Service of the clinic was evaluated. All the patients who underwent their first upper digestive endoscopy with urease test and/or histological analysis were included. The data were submitted to statistical analysis of prevalence by gender, age group and years of study, with subsequent correction through the confidence interval. RESULTS: The mean prevalence of Helicobacter pylori infection thru all years of study was 50.07%. With the calculation of the annual prevalences, it was evident the gradual reduction of infection in the population of Itajaí, that was 81.3% in 1992, declining to 33% in the year of 2016. When classifying the prevalence of infection by gender, it was higher in males (53.59%), and gender distribution by age group showed no statistically significant difference among genders between the ages of 40 and 80 years. In relation to the age group, the highest prevalence was in the group between 40 and 49 years. CONCLUSION: Although this study is retrospective and based on endoscopic database analysis, without access to clinical data of patients such as prior use of proton pump inhibitor and antibiotics to endoscopy, its results are important because they may reflect the current panorama of Helicobacter pylori infection in the city under study, where it has been presenting a gradual reduction of prevalence over the years, with current rates similar to that of developed countries (33%). Future studies are needed to confirm our data.
