Adolescents with disabilities and caregivers experience of COVID-19 in rural Nepal.

Introduction: Intersecting vulnerabilities of disability, low socio-economic status, marginalization, and age indicate that adolescents with disabilities in low-and middle-income countries were uniquely affected by the COVID-19 pandemic. Yet, there has been limited research about their experience. We conducted participatory research with adolescents with disabilities in rural, hilly Nepal to explore their experience of the pandemic and inform understanding about how they can be supported in future pandemics and humanitarian emergencies. Methods: We used qualitative methods, purposively sampling adolescents with different severe impairments from two rural, hilly areas of Nepal. We collected data through semi-structured interviews with five girls and seven boys between the age of 11 and 17 years old. Interviews used inclusive, participatory, and arts-based methods to engage adolescents, support discussions and enable them to choose what they would like to discuss. We also conducted semi-structured interviews with 11 caregivers. Results: We found that adolescents with disabilities and their families experienced social exclusion and social isolation because of COVID-19 mitigation measures, and some experienced social stigma due to misconceptions about transmission of COVID-19 and perceived increased vulnerability of adolescents with disabilities to COVID-19. Adolescents who remained connected with their peers throughout lockdown had a more positive experience of the pandemic than those who were isolated from friends. They became disconnected because they moved away from those they could communicate with, or they had moved to live with relatives who lived in a remote, rural area. We found that caregivers were particularly fearful and anxious about accessing health care if the adolescent they cared for became ill. Caregivers also worried about protecting adolescents from COVID-19 if they themselves got ill, and about the likelihood that the adolescent would be neglected if the caregiver died. Conclusion: Contextually specific research with adolescents with disabilities to explore their experience of the pandemic is necessary to capture how intersecting vulnerabilities can adversely affect particular groups, such as those with disabilities. The participation of adolescents with disabilities and their caregivers in the development of stigma mitigation initiatives and strategies to meet their needs in future emergencies is necessary to enable an informed and inclusive response.

Upper Airway Complications in COVID-19: A Case Series.

Prolonged intubation is associated with several complications leading to upper airway obstruction, including tracheal stenosis and tracheomalacia. Tracheostomy may potentially decrease the risk of tracheal injury in patients with upper airway obstruction. The ideal timing to perform tracheostomy remains controversial. Prolonged intubations were particularly common during the initial phase of the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to present a series of five cases of upper airway complications in patients who underwent mechanical ventilation in the setting of COVID-19 and discuss their clinical aspects, risk factors, and therapeutic strategies.

Irregular Antenatal Care Attendance among Pregnant Women during COVID-19 Pandemic in a Tertiary Care Centre: A Descriptive Cross-sectional Study.

INTRODUCTION: The coronavirus disease 2019 pandemic has made access to antenatal care services difficult, which could lead to serious implications for the health of mothers and fetus. There is limited study regarding its impact on pregnant women. This study aimed to find out the prevalence of irregular antenatal care attendance among pregnant women during the COVID-19 pandemic in a tertiary care centre. METHODS: A descriptive cross-sectional study was carried out among pregnant women attending antenatal care visits at the Department of Gynaecology and Obstetrics in a tertiary care centre from 23 July 2021 to 5 September 2021. Ethical approval was granted by the Institutional Review Committee (Reference number: 077/078/67). Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated. RESULTS: Among 196 pregnant women, 49 (25%) (18.96-31.06, 95% Confidence Interval) had irregular antenatal care attendance during the COVID-19 pandemic. CONCLUSIONS: The prevalence of irregular antenatal care attendance during the COVID-19 pandemic was lower than other studies done in similar settings. Antenatal care is crucial to prevent maternal, fetal morbidity and mortality, hence uninterrupted antenatal care services should be provided even during crisis situation like COVID-19 pandemics.

Hemophagocytic Lymphohistiocytosis Secondary to Prostatic Adenocarcinoma.

Hemophagocytic lymphohistiocytosis (HLH) is caused by excessive immune activation. It can be primary in the setting of genetic defects or secondary in the setting of infection, inflammation, and malignancy. Here we present the fourth reported case of secondary HLH in association with prostatic adenocarcinoma and the diagnostic challenges of this rare, life-threatening condition. This is a 78-year-old male who presented to the hospital with fever and generalized weakness for three days and found to have splenomegaly, pancytopenia, markedly elevated transaminases, and ferritin. Bone marrow biopsy revealed hemophagocytes. He underwent an extensive evaluation to identify the etiology. Para-aortic lymph node biopsy was consistent with prostatic adenocarcinoma. The diagnosis of HLH needs a high index of suspicion because the presentation is nonspecific. HLH is a rapidly progressive and potentially fatal condition underscoring the need for a prompt evaluation if this condition is suspected.

Risk Assessment of Smokeless Tobacco among Oral Precancer and Cancer Patients in Eastern Developmental Region of Nepal

Background: Oral potentially malignant disorders (OPMDs) and oral cancer (OC) are preventable oral mucosal diseases prevalent in Asian region. This epidemiological study aims to identify oral potentially malignant disorders (OPMDs) and oral cancer (OC), confirm histopathologically, and treat or refer these cases among the population of Eastern Development Region (EDR) of Nepal. It also attempts to assess the risk factors associated in order to compare dose­response measurements of oral habits in these patients. Methods: Cross-sectional epidemiological study was conducted over a period of 2 years in 16 districts of EDR. A total of 3,200 people were screened. A brief history was taken and visual screening examination was conducted in two phases as described by British Columbia Oral Cancer Prevention Program. Suspicious oral lesions were biopsied either by punch or scalpel after toluidine blue staining. Tissue specimen was transported to the institutional lab for histopathological processing. The reports were sent to the patients through the local leaders or organizations. Results: More than 40% of the study population either chewed areca nut and/or tobacco. Eighteen percent were smokers. OPMDs were prevalent among 468 study population with male-female ratio of 3:1. Tobacco pouch keratosis (50.4%) was the most prevalent OPMD, followed by OSF (29.1%). Fifty-two had squamous cell carcinoma and 8 had verrucous carcinoma. Conclusion: Chewing areca nut, tobacco, commercial areca nut/tobacco preparation and smoking being the major risk factors, there is high prevalence of oral cancer and OPMDs in the EDR of Nepal.

Prevalence of Different Types of Apical Root Canal Morphology and their Treatment Recommendations in an Institute.

INTRODUCTION: Canals can be of different shapes in cross section including round canals, oval canals, long oval canals or ribbon shaped canals. Recesses of nonround canals may not be included in the round preparation created by rotary instruments and thus they remain unprepared. The aim of this study included determination of shape and taper of the apical root canal based on diameter at different levels. Measurement of the diameter of the root canal at one, two and three mm cross sections from the apex of the tooth were done such that apical instrumentation in root canal treatment could be modified based on the results obtained. METHODS: This was a cross sectional study which used convenient sampling technique to determine the sample size. Seventy extracted teeth were sectioned horizontally at one, two and three millimeter from the apex using the diamond disc which was observed under trinocular research microscope for the determination of diameter of root canal under 10x magnification. Digital images of the sections were taken by a camera attached to the research microscope and analysis done using DigiPro 4.0 software. RESULTS: The most common canal configuration was oval. The taper of the canals was 25% in mesial root and 20% in distal in bucco-lingual orientation and 14% in mesial root and 15% in distal in mesio-distal orientation. CONCLUSIONS: The most prevalent canal configuration in this study was non round, however, most of the rotary instruments tend to prepare root canals into round shape making their use questionable. The taper of the root canals was found to be higher in our study than what most of the shaping instruments have to offer. So it would be advisable to consider this fact while selecting instruments and preparing these non-round canals as far as the Nepalese subpopulation is considered.

Awareness of Undergraduate Dental and Medical Students Towards Oral Cancer.

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.

Developmental anomalies affecting the morphology of teeth - a review

Introduction:The development of tooth is a complex process wherein there is series of interactions between the ectoderm and ectomesenchyme. The role of genes in determining the shape and form of a specific tooth has already been defined, the alterations in which can lead to a variety of anomalies in regards to number, size, form, shape, structure, etc. Objective: To review the literature on the developmental anomalies of teeth. Literature review: The developmental anomalies affecting the morphology exists in both deciduous & permanent dentition and shows various forms such as gemination, fusion, concrescence, dilacerations, dens evaginatus, dens invaginatus, enamel pearls, taurodontism or peg laterals. These anomalies have clinical significance concerning esthetics, malocclusion and more importantly predisposing the development of dental caries and periodontal diseases. Conclusion: Knowledge of various diagnostic criteria for identification of these developmental anomalies is significant for early diagnosis and pertinent treatment.
