RESUMEN
Oral diseases caused by various microorganisms are common around the world. Scientific research has now been focusing on novel medicines to overcome bacterial resistance and antibiotics side effects; therefore, the current study was designed to assess the efficacy of certain antibiotics, toothpaste, and medicinal plant extracts (Ajuga bracteosa and Curcuma longa) versus the bacterial pathogens isolated from the human oral cavity. A total of 130 samples were collected from Khyber Teaching Hospital Peshawar, Pakistan, among those 27 species isolated, and eight bacterial species were identified from the samples. Among all the bacterial species, Staphylococcus aureus (29.62%) and Proteus mirabilis (22.2%) were found to be more prevalent oral pathogens. In comparison, the least pervasive microbes were Proteus vulgaris, Shigella sonnei, Escherichia coli and Aeromonas hydrophila. The study also suggested that dental problems were more prevalent in males (41-50 years of age) than females. Among the eight antibiotics used in the study, the most promising results were shown by Foxicillin against A. hydrophila. The survey of TP1 revealed that it showed more potent antagonist activity against Proteus vulgaris as compared TP2 and TP3 that might be due to the high content of fluoride. The Curcuma longa showed more significant activity than Ajuga bracteosa (Stem, leaves and root) extracts. The data obtained through this study revealed that antibiotics were more effective for oral bacterial pathogens than toothpaste and plant extracts which showed moderate and low activity, respectively. Therefore, it is suggested that the active compounds in individual medicinal plants like Curcuma longa and Ajuga bracteosa could replace the antibiotics when used in daily routine as tooth cleansers or mouth rinses.
As doenças bucais causadas por vários microrganismos são comuns em todo o mundo. A pesquisa científica agora tem se concentrado em novos medicamentos para superar a resistência bacteriana e os efeitos colaterais dos antibióticos; portanto, o presente estudo foi desenhado para avaliar a eficácia de certos antibióticos, pasta de dente e extratos de plantas medicinais (Ajuga bracteosa e Curcuma longa) contra os patógenos bacterianos isolados da cavidade oral humana. No total, 130 amostras foram coletadas do Khyber Teaching Hospital Peshawar, Paquistão, entre essas, 27 espécies foram isoladas e oito espécies bacterianas foram identificadas a partir das amostras. Entre todas as espécies bacterianas, Staphylococcus aureus (29.62%) e Proteus mirabilis (22.2%) foram os patógenos orais mais prevalentes. Em comparação, os micróbios menos difundidos foram Proteus vulgaris, Shigella sonnei, Escherichia coli e Aeromonas hydrophila. O estudo também sugeriu que os problemas dentários eram mais prevalentes em homens (41-50 anos de idade) do que em mulheres. Entre os oito antibióticos usados no estudo, os resultados mais promissores foram mostrados pelo Foxicillin contra A. hydrophila. A pesquisa de TP1 revelou que ele mostrou atividade antagonista mais potente contra Proteus vulgaris em comparação a TP2 e TP3, o que pode ser devido ao alto teor de flúor. A Curcuma longa apresentou atividade mais significativa em relação aos extratos de Ajuga bracteosa (caule, folhas e raiz). Os dados obtidos neste estudo revelaram que os antibióticos foram mais eficazes para os patógenos bacterianos orais do que os dentifrícios e os extratos vegetais que apresentaram atividade moderada e baixa, respectivamente. Portanto, sugere-se que os compostos ativos em plantas medicinais individuais como Curcuma longa e Ajuga bracteosa possam substituir os antibióticos quando usados na rotina diária como limpadores de dentes ou enxaguatórios bucais.

This cross sectional analytical type of study was conducted at department of Anatomy, Dhaka Medical College, Dhaka, Bangladesh from July 2015 to June 2016 on 50 adult Bangladeshi male sprinters (Group A) and 50 adult Bangladeshi male cricket batsman (Group B). Sample collection was done by convenient purposive sampling technique. History of any injury of hand during playing was excluded to construct standard measurement. Hand breadth was measured with the help of slide calipers. Hand grip strength Dynamometer was used to measure the hand grip strength. Paired Student's 't' test, unpaired student's 't' test and Pearson's correlation coefficient test were done for statistical analysis of the result. The aim of the present study was to determine hand breadth and average hand grip strength of Bangladeshi male cricket batsman to find out correlation between them that may be used as a baseline for other professions as well for future research in our country. The mean right and left hand grip strength was significantly higher in the cricket batsman than in the sprinters. The mean right and left hand breadth was found to be significantly higher in the cricket batsman than in the sprinters. Right and left hand grip strength showed significant positive correlation with hand breadth in both hand. The study findings suggest that regular physical exercise and training increase hand grip strength.

This cross-sectional and population based study was carried out in four randomly selected Upazila of four districts of Dhaka division by the department of Obstetrics and Gynaecology of Dhaka Medical College Hospital (DMCH) and Bangabandhu Sheikh Mujib University (BSMMU), Dhaka, Bangladesh from October 2014 to March 2015 to detect the prevalence of Cervical Intraepithelial Neoplasia (CIN) among women in four Upazila of Dhaka division of Bangladesh. Married women ages between 25-55 years, mentally able to provide informed consent were recruited. Women with chronic illness, pregnancy and women with previous treatment for CIN were excluded from the study. During 6 months of study period, a total 1165 cases were examined. Most of the attendants were between 30-35 years. Muslim participants were more than Hindus (95.27% vs. 4.37%) and 0.34% attendants were from Christian religion. Among the participants majority (42.37%) of them were up to primary level. Most (98.45%) of the women were house wife and most (54.5%) of them had monthly family income between Tk. 5001-10000. It was observed that 6.5% of their husband had 2 wives and 1.2% had 3 wives. Regarding their living status, 90.6% were living together, 8.6% of their husband was living at their work place & 0.7% was living abroad. About 30.4% of their husbands were farmer others were businessman, unemployed, driver and other service holder. It was found that 67(5.8%) out of 1165 cases were diagnosed as VIA +ve cases. Among 1165 cases 94.2% were normal, 4.7% were diagnosed as CIN I, 1% were CIN II and none of them was CIN III. Colposcopy guided punch biopsy were taken from all CIN cases and found that among 67 cases of colposcopically diagnosed CIN, histopathologically 28(2.4%) cases were diagnosed as normal, 32(2.7%) cases were CIN I, 4(0.3%) cases were CIN II & 3 (0.3%) cases were CIN III. In this study, crude prevalence of CIN I, CIN II and CIN III were 2.7%, 0.3% and 0.3% respectively. This study provides the first population-based prevalence of CIN in Bangladesh which will guide the Government of Bangladesh to upgrade the activities of already existing cervical cancer screening programme.

Juvenile Nasopharyngeal Angiofibroma (JNA) is an uncommon, benign and extremely vascular tumour which accounts for 0.05-0.5% of all head and neck tumours. Now a day, endoscopic excision is a preferred surgery for early cases. This study was done with the aim to compare the outcomes and complications between endoscopic and conventional surgery of JNA. This cross sectional observational study was conducted in the Department of Otolaryngology & Head-Neck Surgery at Mymensingh Medical College Hospital, Mymensingh and Bangabandhu Sheikh Mujib Medical University, Dhaka from 8 March 2014 to 7 March, 2015. A total number of 20 cases were purposively selected and patient with intracranial extension were excluded from the study. Data was analyzed with SPSS software. Among the 20 patients, maximum 18(90%) were in 2nd decade, age was ranging from 11-33 years, mean 16.17 years. Maximum patients 13(65%) came with nasal obstruction and epistaxis and majority 13(65%) of them were in stage II. Endoscopic excision was done in 12(60%) cases and conventional surgery was done in 7(35%) cases. Mean hospital stay of endoscopic and conventional group was 4.62 vs. 10.23 days. Mean blood loss and mean operative time were 528.12ml vs. 1050ml and 2 hours 17 minutes vs. 3 hours 28 minutes respectively. Per-operative and postoperative complication were more (53.85%) in conventional surgery group. Endoscopic excision of nasopharyngeal angiofibroma is more preferable due to less operative time, less hospital stay, less per-operative blood loss and less complications. But in advanced cases conventional surgery and combined surgery is preferred.

Chronic otitis media is a common condition seen in patients attending the otorhinolaryngology Department. The discharging ear presents the otologists with the dilemma of operating on it or not. The aim of the this cross-sectional observational study was to find out the outcome of surgery in chronic inactive mucosal otitis media and was conducted on 62 patients of either sex in the age group of 15-60 years in the Department of ENT and Head Neck surgery, Shaheed Suhrawardy Medical College Hospital (ShSMCH), Dhaka, Bangladesh From July 2015 to January 2016. Pre and post operative hearing assessment was done with pure tone audiometry (PTA). Post operative graft status also noted. All the information's were recorded in the fixed protocol. Collected data were classified, edited, coded and entered into the computer for statistical analysis by using updated computerized program SPSS-19. Among 62 cases the mean age were 36.79±10.33 in chronic inactive mucosal otitis media. Majority of the study population were in age group of between 15-25 in this group of which was 16(51.6%). Male were 36(58.06) and 26(41.94) were female. All patients presented with history of otorrhoea in this group, 52(83.87%) had hearing impairment in chronic inactive mucosal otitis media, 30(48.39%) involved in right ear and 26(41.94%) involved in left ear and 06(9.68%) in both ear in chronic inactive mucosal otitis media. Majority of perforation were medium in size in this group of which was 30(48.39%). anterior perforation was 24(38.71%), posterior perforation 28(45.16%) and subtotal 10(16.13%) in chronic inactive mucosal otitis media. Sixty two (100%) cases underwent myringoplasty. Post-auricular approach used in most of operation in this group of which was 60(96.77%). Preoperative air conduction threshold 32(51.61%) were in between 31-45 dB in myringoplasty group (p<0.05) that was statistically significant. Postoperative air conduction threshold 30(48.39%) were between 16-30 dB in myringoplasty group (p<0.05) that was statistically significant. Difference between preoperative and postoperative air conduction threshold mean difference was 11.38 dB and 36.75±5.84 and 25.37±7.46 respectively (p<0.001) in myringoplasty group. Hearing gain was 42(67.74%) in myringoplasty (p>0.05) that was not statistically significant. Graft uptake in myringoplasty was 52(83.9%). Graft failure in myringoplasty was 10(16.1%). post operative complication was tinnitus in 12(19.35%) cases in myringoplasty. Success rate was more in case of posterior perforation than anterior and subtotal perforation in both chronic inactive mucosal otitis media which was 92.86%. Success rate was more in case of medium size perforation than subtotal perforation in chronic inactive mucosal otitis media which was 86.67%. Success rate was (100%) in small perforation in this group. From this study it can be concluded that myringoplasty is a valid treatment modality for chronic inactive mucosal otitis media to achieve an intact tympanic membrane and to gain hearing.

Hepatitis C virus (HCV) chronically infects 2%-3% of the world's population, causing liver disease and cancer with prolonged infection. The narrow host range of the virus, being restricted largely to human hepatocytes, has made the development of relevant models to evaluate the efficacy of vaccines a challenge. We have developed a novel approach to accomplish this by generating a murine hepatoma cell line stably expressing nonstructural HCV antigens which can be used in vitro or in vivo to test HCV vaccine efficacies. These HCV-recombinant hepatoma cells formed large solid-mass tumours when implanted into syngeneic mice, allowing us to test candidate HCV vaccines to demonstrate the development of an HCV-specific immune response that limited tumour growth. Using this model, we tested the therapeutic potential of recombinant anti-HCV-specific vaccines based on two fundamentally different attenuated pathogen vaccine systems-attenuated Salmonella and recombinant adenoviral vector based vaccine. While attenuated Salmonella that secreted HCV antigens limited growth of the HCV-recombinant tumours when used in a therapeutic vaccination trial, replication-competent but noninfectious adenovirus expressing nonstructural HCV antigens showed overall greater survival and reduced weight loss compared to non-replicating nondisseminating adenovirus. Our results demonstrate a model with anti-tumour responses to HCV nonstructural (NS) protein antigens and suggest that recombinant vaccine vectors should be explored as a therapeutic strategy for controlling HCV and HCV-associated cancers.

C-reactive protein (CRP) is a sensitive physiological biomarker of sub-clinical inflammation associated with hyperglycemia, insulin resistance and type 2 diabetic patients. A cross sectional study of 120 subjects attending outpatient department of Mymensingh Medical College, Mymensingh was done with an aim to evaluate serum C-reactive protein in type 2 diabetic patients and compare with age matched non-diabetic persons from July 2014 to June 2015. Of the total cases, 60 were Type 2 diabetic patients and 60 were apparently healthy non-diabetic persons recruited for the study. These diabetic and non-diabetic subjects were classified as male (50%) and female (50%). Fasting blood glucose and CRP were measured by following the standard laboratory methods. The mean CRP level was 16.48±12.69mg/L and <6.00±0.00mg/L in diabetic patients and non-diabetics respectively. The study revealed that fasting blood glucose and C-reactive protein were significantly higher in diabetic patients compared with age matched non-diabetic subjects. There was no significant difference in CRP between diabetic males and diabetic females. It was concluded from the results of this study that, CRP level was elevated in both male and female diabetic patients. These data can support a possible role of inflammatory biomarker in diabetogenesis.

INTRODUCTION: Liposomal vesicles (archaeosomes) composed of total polar lipids (TPL) or semi-synthetic glycerolipids, unique to the domain Archaea, constitute potent vaccine adjuvant and delivery systems. The characteristics of this adjuvant offer a novel prospect for the development of effective vaccines for emerging infections and cancers, which is reviewed in this article. Areas covered: The areas covered in this review include the chemical composition and physical characteristics, various in-vitro and in-vivo pre-clinical immunogenicity and efficacy studies for systemic immunization, induction of mucosal immunity upon modification of the formulation with cations, and the mechanism of adjuvant action following uptake by antigen presenting cells. Expert commentary: The unique features of archaeal lipids confer archaeosomes with many desirable features. With the use of semi-synthetic archaeosomes, highly defined lipids that are safe and robust for induction of cell-mediated immunity may be chosen. These adjuvants function as Toll-like receptor-independent innate immune stimulants.

BACKGROUND: Neuroendocrine (NEN) tumours are the commonest type of tumours affecting the appendix. The majority of cases are diagnosed incidentally on post-operative histopathological examination of the resected appendicectomy specimen. Preoperative diagnosis remains a challenge, unless the patient presents with obvious features of carcinoid syndrome or signs of metastatic disease. Hence, the authors present our five-year experience in diagnosing and managing NEN tumours of the appendix. METHODS: Retrospective review of all patients underwent an emergency appendicectomy with intention to treat clinically suspected appendicitis at Derriford Hospital (Plymouth, Devon, UK) was undertaken. Patients with diagnoses other than NEN of the appendix were excluded. For patients with appendicular NEN, demographic data, pre-operative inflammatory markers, post-operative histology results as well as follow-up investigations were obtained using patients' electronic records. Case notes were reviewed for clinical presentation, operative details and follow-up information. RESULTS: 2724 patients underwent emergency appendicectomy between January 2009 and May 2014. Carcinoid tumours were identified in 17 histologically examined appendicectomy specimens. Clinically, all patients presented with acute appendicitis with raised inflammatory markers in 58.5% of patients. Median tumour size was 5 (1-20) mm. Median postoperative follow up was 2.9 (0.92-5.8) years. All patients remained tumour free with no evidence of metastasis or recurrence during the entire study period. CONCLUSION: Appendicular NEN are rare and usually diagnosed incidentally; hence precise examination of routine appendicectomy specimens is fundamental in the diagnosis. Simple appendicectomy is sufficient for tumours less than 1 cm for adequate clearance, whilst right hemi-colectomy is recommended for larger tumours.

The present study compares plasma fibrin network characteristics of fetal blood and that of normal and diabetic pregnant women. Plasma fibrinogen concentration, clotting curves, mass-length ratio of the fibrin fibers, gross permeability and tensile strength of the networks, have been measured. Plasma glucose and glycated hemoglobin are used as glycemic index in diabetic gestational women. The fetal plasma has a lower concentration of fibrin and exhibits delayed clotting, the networks are made up of thinner fibers, are more cross-linked, have lower permeability, and increased tensile strength than in normal adults. The tensile strength of the networks prepared from the plasma of diabetic gestational women are more highly crosslinked than those made from plasma of normal women of corresponding length of pregnancy. The fibrin fiber-thickness is increased during the first and second trimester but is significantly reduced during the third trimester in the diabetic gestational women. The gross permeability of the networks is significantly reduced during the second and third trimester in the diabetic gestational women. The SDS-PAGE shows characteristic pattern of alpha, beta, and gamma-polypeptides in both normal and diabetic gestational women.
