RESUMO

In Queensland, Australia, 31 of 96 Shiga toxin‒producing Escherichia coli cases during 2020-2022 were reported by a specialty pathology laboratory servicing alternative health practitioners. Those new cases were more likely to be asymptomatic or paucisymptomatic, prompting a review of the standard public health response.

RESUMO

OBJECTIVES: This study was conducted to assess oral hygiene practices, oral health status and barriers to utilization of oral health care services among pregnant mothers attending two family health care clinics in Sunsari, Nepal. METHODS: A cross-sectional study was conducted among 139 women using a purposive sampling technique. The data collection was done using a pretested standard semi-structured questionnaire. Face-to-face interviews of the participants were done by a single investigator in the local language (Nepali). The examination was done using a mouth mirror and CPI probe for periodontal status, loss of attachment and dentition status, and treatment needs. RESULTS: The majority of pregnant mothers brushed their teeth once a day or less than once a day (n = 106, 76.3%) and self-reported perceived oral health status was poor/fair (n = 93, 66.9%). The prevalence of dental caries was found to be 69.8%. Bleeding on probing was present in all participants. DMFT, presence of bleeding on probing and increased periodontal pocket was significantly high among women who had self-reported their oral health problems in comparison to those who had not reported any problem. The most common barriers reported by the participants were a lack of knowledge of dental checkups and a lack of perceived need for dental care during pregnancy. CONCLUSIONS: There was a high prevalence of dental caries and periodontal disease. Lack of knowledge and perceived need for dental care were the major barriers found in this study. Hence, this directs towards the utmost need for improvement in awareness level as well as oral hygiene practices.

RESUMO

INTRODUCTION: The purpose of the study was to engage community members and practice partners across multiple sectors in a participatory strategy development process to identify social and organizational determinants of accessing health care, collectively prioritize identified issues, and develop strategies for change. METHODS: Using concept mapping, a mixed-methods approach, a collaborative team of academics, practice partners, and community health workers collected data from community members and agency representatives (n=366) across four counties through facilitated community forums and an online survey in four counties in the Bootheel region of Missouri, USA. These responses were consolidated into a set of statements that were used with a smaller group of participants (n=60, 15 per county) for sorting and rating purposes. The resulting concept maps were presented to community participants, who were guided through a structured process for prioritization of issues and strategy development. RESULTS: Participants identified several individual-, social-, community-, and organization-level barriers to accessing health care, including cost, lack of transportation, lack of information about services, lack of coordinated care, lack of trust, and racism and classism in local healthcare systems. CONCLUSION: While the key social and organizational determinants of access to health care were similar across counties, the prioritization of these determinants and the strategies developed to address key issues differed across the counties.

RESUMO

Background: Transanal minimally invasive surgery (TAMIS) was described in the literature 10 years ago. This procedure requires laparoscopic technical skills. It has been well accepted widely worldwide. TAMIS has been applied to multiple procedures, including excision for rectal polyps and cancer, with acceptable outcomes. The study aimed to assess the outcomes of TAMIS in a large district general hospital. Methodology: A retrospective study on prospectively collected data on 52 consecutive patients of TAMIS performed in a single unit was conducted between May 2014 and February 2020. Data were collected on patient demographics, clinical diagnosis, peri-operative findings, pathological findings, adequacy of excision and complications. Patients were followed up as per the trust and national post-polypectomy guidelines. Results: Among the 52 patients, TAMIS procedures were completed in 50 patients, of which 31 were female. The procedure was successful in 96.5% but had to abandon in two cases. There was no conversion to another procedure. Pre-operative indications were rectal polyps and one case was an emergency TAMIS in a patient who was bleeding following incomplete colonoscopic polypectomy. The final histology reported that the majority were benign polyps (46), and only 11 cases were malignant. The median distance of the lesion from the anal verge was 6 cm (3-10 cm). The median operative time was 55 min (8-175 min). A total of 45 (77.5%) lesions were completely excised and had negative microscopic margins. Most patients (64%) were discharged home the same day. No complications were observed at a median follow-up of 20 months (6-48 months). There was no mortality. Conclusions: Our data suggest that TAMIS can be safely performed in a district general hospital for both benign and early rectal cancer. TAMIS was also able to control post-polypectomy bleeding and completion of rectal polypectomy. In selected cases, day-case TAMIS is safe and feasible.

RESUMO

OBJECTIVES: The objectives of this study were to: (1) study the prevalence of oral habits among school going children with primary dentition; (2) determine the association of oral habits with malocclusion in primary dentition; and (3) compare the prevalence of oral habits based on gender, race, age and grade. STUDY DESIGN: A community based cross-sectional study was conducted among 625 school going children with a complete set of primary dentitions. A closed-ended questionnaire was developed to gather information about oral habits followed by clinical examination. RESULTS: The prevalence of oral habits was 42.7%. Finger nail biting (19.5%) was the most prevalent oral habit, whereas self-destructive oral habits (0.7%) were the least prevalent. Multivariate logistic regression analysis revealed significant association of (P<0.05): digit sucking habit with distal step molar relationship, class II canine relationship and increased overjet; pacifier sucking habit with presence of distal step molar relationship, class II canine relationship, crossbite and increased overjet; and finger nail biting habit with absence of primate spaces. CONCLUSIONS: Nearly half of the participating children indulged in one or more oral habits. There was significant association between some oral habits and malocclusion traits, indicating the requirement of timely screening and interception.

RESUMO

BACKGROUND: Despite NICE/AUGIS recommendations, the practice of early laparoscopic cholecystectomy (ELC) has been particularly poor in the UK offered only by 11%-20% surgeons as compared to 33%-67% internationally, possibly due to financial constraints, logistical difficulties and shortage of expertise, thus, reflecting the varied provision of emergency general surgical care. To assess whether emergency general surgeons (EGS) could provide a 'Hot Gall Bladder Service' (HGS) with an acceptable outcome. PATIENTS AND METHODS: This was a prospective HGS observational study that was protocol driven with strict inclusion/exclusion criteria and secure online data collection in a district general hospital between July 2018 and June 2019. A weekly dedicated theatre slot was allocated for this list. RESULTS: Of the 143 referred for HGS, 86 (60%) underwent ELC which included 60 (70%) women. Age, ASA and body mass index was 54* (18-85) years, II* (I-III) and 27* (20-54), respectively. 86 included 46 (53%), 19 (22%), 19 (22%) and 2 (3%) patients presenting with acute calculus cholecystitis, gallstone pancreatitis, biliary colic, and acalculus cholecystitis, respectively. 85 (99%) underwent LC with a single conversion. Grade of surgical difficulty, duration of surgery and post-operative stay was 2* (1-4) 68* (30-240) min and 0* (0-13) day, respectively. Eight (9%) required senior surgical input with no intra-operative complications and 2 (2%) 30-day readmissions. One was post-operative subhepatic collection that recovered uneventfully and the second was pancreatitis, imaging was clear requiring no further intervention. CONCLUSION: In the current climate of NHS financial crunch, COVID pandemic and significant pressure on inpatient beds: Safe and cost-effective HGS can be provided by the EGS with input from upper GI/HPB surgeons (when required) with acceptable morbidity and a satisfactory outcome. *Median.

RESUMO

BACKGROUND: Nicotine is a highly addictive substance present in tobacco. This study was conducted to assess the level of nicotine dependence among smokers and smokeless tobacco users visiting dental outreach programs of B.P. Koirala Institute of Health Sciences -Dharan, Nepal. METHODS: A cross sectional study was conducted from June 2018 to April 2019. A total of 726 people were selected from participants of dental outreach programs of 6 districts using convenience sampling technique. The data collection was done using semi-structured questionnaire through face-to-face interview by a single researcher. History of tobacco use and level of nicotine dependency was measured using Nepali translated and validated form of Fagerström Test for Nicotine Dependence for smoking and smokeless tobacco. The mean age of the tobacco users was 39.55 ± 15.57. Descriptive statistics including the mean, median, percentage, standard deviations and interquartile range were computed. Chi-square test, Fisher's exact test, univariate and bivariate logistic regression were used where needed. RESULTS: Nicotine dependence (moderate and severe) was found in 80% of smokeless tobacco users and 48% of smokers. Among the smokeless tobacco users, nicotine dependency was found to be more with increase in duration of tobacco use (AOR = 50.25, 95%CI = 3.51-718.62, p = 0.004), low socioeconomic status (AOR = 6.27, 95%CI = 1.30-30.31, p = 0.02), less number of tobacco packets used per day and tried to quit tobacco use in last 1 year. Among smokers nicotine dependency was found to be significantly higher with smoking more than 10 cigarettes per day (AOR = 7.14, 95% CI = 2.00-25.40, p = 0.002). CONCLUSIONS: The study concluded that level of nicotine dependence for both smoking and smokeless tobacco was high among the people visiting dental outreach programs. It is high time to develop a policy to control tobacco use along with creating tobacco cessation centers. Currently, tobacco control program is mostly focusing on smoking. However, it is also important to incorporate smokeless tobacco control at policy level.

RESUMO

BACKGROUND: Effective training is vital when facing viral outbreaks such as the SARS Coronavirus 2 (SARS-CoV-2) outbreak of 2019. The objective of this study was to measure the impact of in-situ simulation on the confidence of the surgical teams of two hospitals in assessing and managing acutely unwell surgical patients who are high-risk or confirmed to have COVID-19. METHODS: This was a quasi-experimental study with a pretest-posttest design. The surgical teams at each hospital participated in multi-disciplinary simulation sessions to explore the assessment and management of a patient requiring emergency surgery who is high risk for COVID-19. The participants were surveyed before and after receiving simulation training to determine their level of confidence on a Visual Analog Scale (VAS) for the premise stated in each of the nine questions in the survey, which represented multiple aspects of the care of these patients. RESULTS: 27 participants responded the pre-simulation survey and 24 the one post-simulation. The level of confidence (VAS score) were statistically significantly higher for all nine questions after the simulation. Specific themes were identified for further training and changes in policy. CONCLUSION: In-situ simulation is an effective training method. Its versatility allows it to be set up quickly as rapid-response training in the face of an imminent threat. In this study, it improved the preparedness of two surgical teams for the challenges of the COVID-19 pandemic.

RESUMO

BACKGROUND: School-aged adolescents are in particular need of preventive program to ensure positive long-term oral health and hygiene. The objective of this study was to assess the effectiveness of an oral health education (OHE) intervention on oral hygiene knowledge, attitude and practices (KAP), plaque control and gingival health among 12-15 years old school children in Dharan sub-metropolitan city, Nepal. METHODS: A randomized controlled trial was conducted with parallel study groups, comprising 12-15-year-old school children, 120 in each group. OHE was given to the experimental group at baseline, third and sixth months and to the control group after completion of the study. Interview of the participants were done using a 23-item questionnaire for assessment of oral hygiene KAP. For each question, correct answer was scored as 1 and wrong answer was scored zero. An overall composite score was then created, by adding the individual scores. Oral examination was done using mouth mirror and WHO probe to record Turesky-Gilmore-Glickman modification of the Quigley-Hein plaque index, Gingival index and Dentition status and treatment needs. Analysis was done using chi-square test for categorical data and independent t test, Mann-Whitney U test, repeated measures ANOVA and post hoc Tukey's test for quantitative data. The level of significance was set at P < 0.05. RESULTS: There was 54.58% improvement in overall oral hygiene KAP in experimental group (P = 0.001) whereas no improvement was seen in control group at the end of the study. The mean plaque score was improved by 57.67% (P = 0.001) in experimental group in comparison to 4.56% in control group. Gingival index was improved by 49.90% (P = 0.001) in experimental group in comparison to 0.7% in control group. Caries experience was increased in both groups but no significant difference was seen. CONCLUSIONS: The study concluded that oral health education was effective in improving oral hygiene KAP, plaque control and gingival health. Trial registration The trial was retrospectively registered with Clinical Trial Registry India (CTRI) with identifier no. CTRI/2018/05/013985, registered on 05/21/2018.

RESUMO

BACKGROUND: Periodontal probing is one of the basic clinical oral examination procedures. It is carried out to assess the severity of gingival and periodontal disease. The experience of pain during probing may discourage patients. So, this study was conducted to estimate the pain perception and dental anxiety experienced during periodontal probing in patients visiting the community oral health programmes of B. P. Koirala Institute of Health Sciences (BPKIHS). METHODS: A cross-sectional study was conducted among 100 participants of community oral health programmes of BPKIHS. Demographic profile, WHO modified Community Periodontal Index (CPI) 2013, Pain perception via Visual Analogue Scale (VAS Scores) and Short Version of Spielberger State-Trait Anxiety Inventory (STAI) Self-evaluation Questionnaire (Y-6 item) were assessed. Mean ± SD and Spearman correlation for pain and anxiety were computed. RESULTS: Only 10% of the study participants had healthy gingiva and 12% had periodontal pockets. Pain perception and dental anxiety was present in the participants. The participants experienced very little pain (6.75 ± 10.65) during periodontal probing. The overall anxiety score was 13.37 ± 1.81. There was a very weak correlation between the VAS Scores and the anxiety scores of the participants. CONCLUSION: This study concludes that pain perception and anxiety are low during periodontal probing. There was no correlation between bleeding on probing with pain and anxiety among the people visiting community oral health programmes of BPKIHS.

RESUMO

Hepatitis C virus (HCV) is a significant contributor to the global disease burden, and development of an effective vaccine is required to eliminate HCV infections worldwide. CD4+ and CD8+ T cell immunity correlates with viral clearance in primary HCV infection, and intrahepatic CD8+ tissue-resident memory T (TRM) cells provide lifelong and rapid protection against hepatotropic pathogens. Consequently, we aimed to develop a vaccine to elicit HCV-specific CD4+ and CD8+ T cells, including CD8+ TRM cells, in the liver, given that HCV primarily infects hepatocytes. To achieve this, we vaccinated wild-type BALB/c mice with a highly immunogenic cytolytic DNA vaccine encoding a model HCV (genotype 3a) nonstructural protein (NS5B) and a mutant perforin (pVAX-NS5B-PRF), as well as a recombinant adeno-associated virus (AAV) encoding NS5B (rAAV-NS5B). A novel fluorescent target array (FTA) was used to map immunodominant CD4+ T helper (TH) cell and cytotoxic CD8+ T cell epitopes of NS5B in vivo, which were subsequently used to design a KdNS5B451-459 tetramer and analyze NS5B-specific T cell responses in vaccinated mice in vivo The data showed that intradermal prime/boost vaccination with pVAX-NS5B-PRF was effective in eliciting TH and cytotoxic CD8+ T cell responses and intrahepatic CD8+ TRM cells, but a single intravenous dose of hepatotropic rAAV-NS5B was significantly more effective. As a T-cell-based vaccine against HCV should ideally result in localized T cell responses in the liver, this study describes primary observations in the context of HCV vaccination that can be used to achieve this goal.IMPORTANCE There are currently at least 71 million individuals with chronic HCV worldwide and almost two million new infections annually. Although the advent of direct-acting antivirals (DAAs) offers highly effective therapy, considerable remaining challenges argue against reliance on DAAs for HCV elimination, including high drug cost, poorly developed health infrastructure, low screening rates, and significant reinfection rates. Accordingly, development of an effective vaccine is crucial to HCV elimination. An HCV vaccine that elicits T cell immunity in the liver will be highly protective for the following reasons: (i) T cell responses against nonstructural proteins of the virus are associated with clearance of primary infection, and (ii) long-lived liver-resident T cells alone can protect against malaria infection of hepatocytes. Thus, in this study we exploit promising vaccination platforms to highlight strategies that can be used to evoke highly functional and long-lived T cell responses in the liver for protection against HCV.

RESUMO

In this study, a simple and customizable convolution neural network framework was used to train a vibration classification model that can be integrated into the measurement application in order to realize accurate and real-time bridge vibration status on mobile platforms. The inputs for the network model are basically the multichannel time-series signals acquired from the built-in accelerometer sensor of smartphones, while the outputs are the predefined vibration categories. To verify the effectiveness of the proposed framework, data collected from long-term monitoring of bridge were used for training a model, and its classification performance was evaluated on the test set constituting the data collected from the same bridge but not used previously for training. An iOS application program was developed on the smartphone for incorporating the trained model with predefined classification labels so that it can classify vibration datasets measured on any other bridges in real-time. The results justify the practical feasibility of using a low-latency, high-accuracy smartphone-based system amid which bottlenecks of processing large amounts of data will be eliminated, and stable observation of structural conditions can be promoted.

RESUMO

BACKGROUND: Neurokine signaling via the release of neurally active cytokines arises from glial reactivity and is mechanistically implicated in central nervous system (CNS) pathologies such as chronic pain, trauma, neurodegenerative diseases, and complex psychiatric illnesses. Despite significant advancements in the methodologies used to conjugate, incorporate, and visualize fluorescent molecules, imaging of rare yet high potency events within the CNS is restricted by the low signal to noise ratio experienced within the CNS. The brain and spinal cord have high cellular autofluorescence, making the imaging of critical neurokine signaling and permissive transcriptional cellular events unreliable and difficult in many cases. METHODS: In this manuscript, we developed a method for background-free imaging of the transcriptional events that precede neurokine signaling using targeted mRNA transcripts labeled with luminescent lanthanide chelates and imaged via time-gated microscopy. To provide examples of the usefulness this method can offer to the field, the mRNA expression of toll-like receptor 4 (TLR4) was visualized with traditional fluorescent in situ hybridization (FISH) or luminescent lanthanide chelate-based in situ hybridization (LISH) in mouse BV2 microglia or J774 macrophage phenotype cells following lipopolysaccharide stimulation. TLR4 mRNA staining using LISH- and FISH-based methods was also visualized in fixed spinal cord tissues from BALB/c mice with a chronic constriction model of neuropathic pain or a surgical sham model in order to demonstrate the application of this new methodology in CNS tissue samples. RESULTS: Significant increases in TLR4 mRNA expression and autofluorescence were visualized over time in mouse BV2 microglia or mouse J774 macrophage phenotype cells following lipopolysaccharide (LPS) stimulation. When imaged in a background-free environment with LISH-based detection and time-gated microscopy, increased TLR4 mRNA was observed in BV2 microglia cells 4 h following LPS stimulation, which returned to near baseline levels by 24 h. Background-free imaging of mouse spinal cord tissues with LISH-based detection and time-gated microscopy demonstrated a high degree of regional TLR4 mRNA expression in BALB/c mice with a chronic constriction model of neuropathic pain compared to the surgical sham model. CONCLUSIONS: Advantages offered by adopting this novel methodology for visualizing neurokine signaling with time-gated microscopy compared to traditional fluorescent microscopy are provided.

RESUMO

OBJECTIVE: To translate and validate the Geriatric Oral Health Assessment Index (GOHAI) (Nepali version) from original English version. BACKGROUND: Growing numbers of elderly people have problems in different aspects of oral health increasing the demand for dental care services among them GOHAI may be one of the effective means of gathering information on oral health problems of the elderly people. MATERIALS AND METHODS: A total of 168 individuals ≥60 years from seven old-age homes located in Eastern Nepal were included in the study. The Nepali version of GOHAI was translated and validated. RESULTS: A total of 168 elderly people (79 male and 89 female participants) completed GOHAI questionnaire. The mean age (±SD) of the participants was 72.49 (±10.00) years. The mean GOHAI score (±SD) was 42.29 (±6.93) and ranged from 17 to 59. Cronbach's alpha coefficient for the Nepali version of GOHAI (GOHAI-N) was 0.74, which is categorised as very good agreement. Analysis of discriminant validity showed that lower mean GOHAI score was seen in study participants with more number of missing and decayed teeth. However, those who had more than one filled surface had higher mean GOHAI score. CONCLUSION: The Nepali version of the GOHAI exhibited acceptable reliability and validity when used for older people residing in old age homes. The GOHAI-N showed good consistency and homogeneity among the items.

RESUMO

BACKGROUND: The sense of taste is very much essential to the overall health of an individual. It is a necessary component to enjoy one's food, which in turn provides nutrition to an individual. Any disturbance in taste perception can hamper quality of life in such patients by influencing their appetite, body weight and psychological well-being. Taste disorders have been treated using different modalities of treatment and there is no consensus for the best intervention. Hence this Cochrane Review was undertaken. This is an update of the Cochrane Review first published in November 2014. OBJECTIVES: To assess the effects of interventions for the management of patients with taste disturbances. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 4 July 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017 Issue 6) in the Cochrane Library (searched 4 July 2017); MEDLINE Ovid (1946 to 4 July 2017); Embase Ovid (1980 to 4 July 2017); CINAHL EBSCO (1937 to 4 July 2017); and AMED Ovid (1985 to 4 July 2017). The US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for trials. Abstracts from scientific meetings and conferences were searched on 25 September 2017. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA: We included all randomised controlled trials (RCTs) comparing any pharmacological agent with a control intervention or any non-pharmacological agent with a control intervention. We also included cross-over trials in the review. DATA COLLECTION AND ANALYSIS: Two pairs of review authors independently, and in duplicate, assessed the quality of trials and extracted data. Wherever possible, we contacted trial authors for additional information. We collected adverse events information from the trials. MAIN RESULTS: We included 10 trials (581 participants), nine of which we were able to include in the quantitative analyses (566 participants). We assessed three trials (30%) as having a low risk of bias, four trials (40%) at high risk of bias and three trials (30%) as having an unclear risk of bias. We only included studies on taste disorders in this review that were either idiopathic, or resulting from zinc deficiency or chronic renal failure.Of these, nine trials with 544 people compared zinc supplements to placebo for patients with taste disorders. The participants in two trials were children and adolescents with respective mean ages of 10 and 11.2 years and the other seven trials had adult participants. Out of these nine, two trials assessed the patient-reported outcome for improvement in taste acuity using zinc supplements (risk ratio (RR) 1.40, 95% confidence interval (CI) 0.94 to 2.09; 119 participants, very low-quality evidence). We meta-analysed for taste acuity improvement using objective outcome (continuous data) in idiopathic and zinc-deficient taste disorder patients (standardised mean difference (SMD) 0.44, 95% CI 0.23 to 0.65; 366 participants, three trials, very low-quality evidence). We also analysed one cross-over trial separately using the first half of the results for taste detection (mean difference (MD) 2.50, 95% CI 0.93 to 4.07; 14 participants, very low-quality evidence), and taste recognition (MD 3.00, 95% CI 0.66 to 5.34; 14 participants, very low-quality evidence). We meta-analysed taste acuity improvement using objective outcome (dichotomous data) in idiopathic and zinc-deficient taste disorder patients (RR 1.42, 95% 1.09 to 1.84; 292 participants, two trials, very low-quality evidence). Out of the nine trials using zinc supplementation, four reported adverse events like eczema, nausea, abdominal pain, diarrhoea, constipation, decrease in blood iron, increase in blood alkaline phosphatase, and minor increase in blood triglycerides.One trial tested taste discrimination using acupuncture (MD 2.80, 95% CI -1.18 to 6.78; 37 participants, very low-quality evidence). No adverse events were reported in the acupuncture trial.None of the included trials could be included in the meta-analysis for health-related quality of life in taste disorder patients. AUTHORS' CONCLUSIONS: We found very low-quality evidence that was insufficient to conclude on the role of zinc supplements to improve taste acuity reported by patients and very low-quality evidence that zinc supplements improve taste acuity in patients with zinc deficiency/idiopathic taste disorders. We did not find any evidence to conclude the role of zinc supplements for improving taste discrimination, or any evidence addressing health-related quality of life due to taste disorders.We found very low-quality evidence that is not sufficient to conclude on the role of acupuncture for improving taste discrimination in cases of idiopathic dysgeusia (distortion of taste) and hypogeusia (reduced ability to taste). We were unable to draw any conclusions regarding the superiority of zinc supplements or acupuncture as none of the trials compared these interventions.

RESUMO

Oral cancer is a common malignancy in Nepal and many other South East Asian countries, which is predisposed by a variety of potentially malignant oral diseases. Considering the importance of knowledge of health professionals and their role in early diagnosis and reduction of cancer statistics, this study aims to evaluate the awareness of undergraduate dental and medical students towards oral cancer. The study involved undergraduate dental and medical students of BP Koirala Institute of Health Sciences, Nepal. A self-administered questionnaire adapted from Carter to Ogden was distributed. One hundred forty-three dental and 311 medical students responded to the questionnaire. Significantly more dental (80.4 %) than medical students (36.0 %) were found to routinely examine the oral mucosa. Tobacco smoking and chewing were the most commonly recognized risk factors by both medical and dental students. Most of the students found ulcer as the common change associated with oral cancer. Only 30 out of the total students felt very well informed about oral cancer. This study has demonstrated a lack of awareness in some aspects of oral cancer among medical and dental students which highlights the need to frame new teaching methodologies. Similar studies from other health institutions would provide an insight regarding the same and could be a base for formulating a uniform curriculum in the implementation of knowledge regarding oral cancer.

RESUMO

BACKGROUND: Hepatitis E virus (HEV) poses a risk to transfusion safety. In Australia, locally acquired HEV is rare and cases are mainly reported in travelers returning from countries endemic for HEV. The risk posed by HEV to transfusion safety in Australia is unknown; therefore, we aimed to measure the rate of current HEV infection in Australian blood donations. STUDY DESIGN AND METHODS: A total of 14,799 blood donations were tested for HEV RNA by transcription-mediated amplification, with confirmatory testing by reverse transcription-polymerase chain reaction. Viral load quantification and phylogenetic analysis was performed on HEV RNA-positive samples. RESULTS: One (0.0068%; 95% confidence interval [CI], 0.0002%-0.0376%) sample was confirmed positive for HEV RNA, resulting in a risk of collecting a HEV-viremic donation of 1 in 14,799 (95% CI, 1 in 584,530 to 1 in 2,657). The viral load in this sample was approximately 15,000 IU/mL, and it was determined to be Genotype 3. DISCUSSION: Our finding of 1 in 14,799 Australian donations positive for HEV RNA is lower than that from many other developed countries; this is consistent with the relatively low seroprevalence in Australia. As this HEV RNA-positive sample was Genotype 3, it seems likely that this infection was acquired through zoonotic transmission, either within Australia or overseas in a developed nation. HEV has the potential to pose a risk to transfusion safety in Australia; however, additional, larger studies are required to quantify the magnitude of this risk.

RESUMO

BACKGROUND: As one of the causative agents of viral hepatitis, hepatitis E virus (HEV) has gained public health attention globally. HEV epidemics occur in developing countries, associated with faecal contamination of water and poor sanitation. In industrialised nations, HEV infections are associated with travel to countries endemic for HEV, however, autochthonous infections, mainly through zoonotic transmission, are increasingly being reported. HEV can also be transmitted by blood transfusion. Nepal has experienced a number of HEV outbreaks, and recent earthquakes resulted in predictions raising the risk of an HEV outbreak to very high. This study aimed to measure HEV exposure in Nepalese blood donors after large earthquakes. METHODS: Samples (n = 1,845) were collected from blood donors from Kathmandu, Chitwan, Bhaktapur and Kavre. Demographic details, including age and sex along with possible risk factors associated with HEV exposure were collected via a study-specific questionnaire. Samples were tested for HEV IgM, IgG and antigen. The proportion of donors positive for HEV IgM or IgG was calculated overall, and for each of the variables studied. Chi square and regression analyses were performed to identify factors associated with HEV exposure. RESULTS: Of the donors residing in earthquake affected regions (Kathmandu, Bhaktapur and Kavre), 3.2% (54/1,686; 95% CI 2.7-4.0%) were HEV IgM positive and two donors were positive for HEV antigen. Overall, 41.9% (773/1,845; 95% CI 39.7-44.2%) of donors were HEV IgG positive, with regional variation observed. Higher HEV IgG and IgM prevalence was observed in donors who reported eating pork, likely an indicator of zoonotic transmission. Previous exposure to HEV in Nepalese blood donors is relatively high. CONCLUSION: Detection of recent markers of HEV infection in healthy donors suggests recent asymptomatic HEV infection and therefore transfusion-transmission in vulnerable patients is a risk in Nepal. Surprisingly, this study did not provide evidence of a large HEV outbreak following the devastating earthquakes in 2015.

RESUMO

AIM: Laparoscopic cholecystectomy (LC) is considered the 'gold standard' intervention for gall bladder (GB) diseases. However, to avoid serious biliovascular injury, conversion is advocated for distorted anatomy at the Calot's triangle. The aim is to find out whether our technique of laparoscopic modified subtotal cholecystectomy (LMSC) is suitable, with an acceptable morbidity and outcome. PATIENTS AND METHODS: A retrospective analysis of prospectively collected data of 993 consecutive patients who underwent cholecystectomy was done at a large District General Hospital (DGH) between August 2007 and January 2015. The data are as follows: Patient's demographics, operative details including intra- and postoperative complications, postoperative stay including follow-up that was recorded and analysed. RESULTS: A total of 993 patients (263 males and 730 female) were included. The median age was 52*(18-89) years. Out of the 993 patients, 979 (98.5%) and 14 (1.5%) were listed for laparoscopic and open cholecystectomy, respectively. Of the 979 patients, 902 (92%) and 64 (6.5%) patients underwent LC ± on-table cholangiography (OTC) and LMSC ± OTC, respectively, with a median stay of 1* (0-15) days. Of the 64 patients, 55 (86%) had dense adhesions, 22 (34%) had acute inflammation, 19 (30%) had severe contraction, 12 (19%) had empyema, 7 (11%) had Mirizzi's syndrome and 2 (3%) had gangrenous GB. The mean operative time was 120 × (50-180) min [Table 1]. Six (12%) patients required endoscopic retrograde cholangiopancreatography (ERCP) postoperatively, and there were four (6%) readmissions in a follow-up of 30 × (8-76) months. The remaining 13 (1.3%) patients underwent laparoscopic cholecystectomy converted to an open cholecystectomy. The median stay for open/laparoscopic cholecystectomy converted to open cholecystectomy was 5 × (1-12) days. CONCLUSION: Our technique of LMSC avoided conversion in 6.5% patients and believe that it is feasible and safe for difficult GBs with a positive outcome.
