RESUMO
Early childhood caries (ECC) is the most common non-communicable childhood disease. It is an important health problem with known environmental and social/behavioral influences that lacks evidence for specific associated genetic risk loci. To address this knowledge gap, we conducted a genome-wide association study of ECC in a multi-ancestry population of U.S. preschool-age children (n=6,103) participating in a community-based epidemiologic study of early childhood oral health. Calibrated examiners used ICDAS criteria to measure ECC with the primary trait using the dmfs index with decay classified as macroscopic enamel loss (ICDAS ≥3). We estimated heritability, concordance rates, and conducted genome-wide association analyses to estimate overall genetic effects; the effects stratified by sex, household water fluoride, and dietary sugar; and leveraged the combined gene/gene-environment effects using the 2-degree-of-freedom (2df) joint test. The common genetic variants explained 24% of the phenotypic variance (heritability) of the primary ECC trait and the concordance rate was higher with a higher degree of relatedness. We identified 21 novel non-overlapping genome-wide significant loci for ECC. Two loci, namely RP11-856F16 . 2 (rs74606067) and SLC41A3 (rs71327750) showed evidence of association with dental caries in external cohorts, namely the GLIDE consortium adult cohort (n=â¼487,000) and the GLIDE pediatric cohort (n=19,000), respectively. The gene-based tests identified TAAR6 as a genome-wide significant gene. Implicated genes have relevant biological functions including roles in tooth development and taste. These novel associations expand the genomics knowledge base for this common childhood disease and underscore the importance of accounting for sex and pertinent environmental exposures in genetic investigations of oral health.
RESUMO
INTRODUCTION: Varicose veins are a common vascular problem with a high prevalence, yet they are often neglected. The main objective of this study was to explore the patient satisfaction after varicose vein surgery, along with its predicting factors. To our knowledge, no similar study has been conducted in Nepal to date. METHODOLOGY: This retrospective cross-sectional study included patients who underwent varicose vein surgery at Dhulikhel Hospital from September 2019 to February 2020. The satisfaction level after the surgery was assessed using a 10-point Likert scale questionnaire during a telephone interview with their verbal consent. Descriptive statistics and linear regression were performed to identify the predicting factors of patient satisfaction. RESULTS: Among a total of 84 patients interviewed, 53.6% were male. The mean age of the participants was 43.13 ± 13.62 years. The mean patient satisfaction score was 42 ± 5.5, with nursing service, discharge teaching and hospital service being the highest scoring items in terms of patient satisfaction. Linear regression revealed age ≤40 years as a predictor of higher patient satisfaction (ß=0.258, p=0.015) while early stage of varicose veins (ß=-0.233, p=0.026) and duration of post-operative follow-up (ß=-0.25, p=0.021) were negative predictors of patient satisfaction. This means that patients with C2-C3 venous disease and longer duration of postoperative follow-up tended to have lower satisfaction scores. CONCLUSION: The overall patient satisfaction following varicose vein surgery was very good, and the major predictors of better satisfaction were age ≤40 years, C4-C6 clinical classification of venous disease and the shorter duration of follow-up after surgery.

Background Glaucoma is one of the major causes of irreversible blindness globally. Almost 60 million people globally are affected by glaucoma making it the second leading cause of blindness worldwide. Diagnosis of glaucoma early on is vital for timely management and prevention of blindness. However, it is challenging to diagnose it early because it is asymptomatic in the initial stage, and there is also the dearth of appropriate screening tools. Awareness, knowledge, and beliefs are believed to influence the treatment-seeking behavior of people as well as their uptake of services. Objective To assess the awareness and knowledge about glaucoma among general patients and patient attendants visiting Dhulikhel Hospital. Method We conducted a cross sectional quantitative study among general patients visiting Dhulikhel Hospital. We collected data using face-to-face interviews with semistructured questionnaires. We analyzed data in R version 4.0.3 (2020-10-10). We presented numerical variables as mean and standard deviation whereas categorical variables as frequency and percentage. We determined factors associated with awareness and knowledge of glaucoma using logistic regression analysis and estimated adjusted odds ratio (AOR) with 95% confidence interval. Result Of 379 participants, a total of 214 (56.5%) participants had heard about glaucoma. Out of the participants who heard about glaucoma, the mean knowledge score was 48.3±21.7 and 53.3% had good knowledge on glaucoma. The odds of having heard about glaucoma were two percent lower (AOR=0.98; 95%CI: 0.97-0.99; p-value 0.036) in the older participants compared to one year younger participant, 1.98 (95%CI:1.01-3.86; p-value 0.046) times higher among literates and 2.79 (95%CI: 1.76- 4.41; p-value < 0.001) times among participants with previous ocular examination. The odds of having good knowledge was 1.94 (95%CI: 1.10-3.42; p value 0.021) times among participants with previous ocular examinations. Conclusion The knowledge and awareness regarding glaucoma in a hospital-visiting population in central Nepal was low. Half of the participants were unaware of the disease glaucoma and half of the participants who heard of the glaucoma had poor knowledge on glaucoma.

The preliminary study examined the effectiveness of various vegetables for the stabilisation of omega-3 oil powders against oxidative deterioration. Purees made from different vegetables (mushroom, brussels sprouts, broccoli, cauliflower, snow peas, tomato, and garlic) were employed for preparation of vegetable-tuna oil emulsions, which were subsequently freeze-dried into powders. Oxipres® data showed that vegetable-tuna oil powders had longer induction periods than neat tuna oil. During accelerated oxidation storage (40 °C/4weeks), eicosapentaenoic and docosahexaenoic acids in the vegetable-tuna oil powders were protected against oxidation, and there were lower levels of headspace secondary and tertiary oxidation products. Whole vegetable purees were suitable protective matrices for omega-3 oils. Of the various vegetable purees examined for protective effects against omega-3 oxidation, mushroom, brussels sprouts, broccoli, and cauliflower were superior to snow peas, garlic and tomato. The antioxidant properties of phytonutrients inherent in various vegetables are likely contributors to protection of omega-3 oil powders against oxidation.

Background Cataract remains the leading cause of avoidable blindness in low-income countries such as Nepal. Despite the availability of surgical interventions for cataract in leading institutions, still a large number of patients from remote areas delay or have difficulty in getting treatment, present late or with complications. Objective To determine the clinical characteristics and visual outcome of patients undergoing cataract surgery in Tertiary Care Hospital in Central Nepal. Method We retrospectively reviewed the medical records of 138 patients who underwent cataract surgery at a tertiary care hospital from January 2018 to September 2022. R version 4.0.3 was used for the data analysis. Categorical variables are presented as frequency (percentages) and the numerical ones are presented as mean (standard deviation). Result During follow-up visits between one to three weeks, 91.9% out of 135 patients had normal/near normal presenting visual acuity and with best correction it was 96.9% out of 131 patients. About 1.6% out of 124 operated eyes still had moderate visual impairment after best correction when they visited for follow-up at 12 weeks. Conclusion The study findings underline the ongoing gap in increasing access to cataract treatment, given the large proportion of individuals who still presented extremely late.

Background Retinal haemorrhage in new-born is a clinically common neonatal fundus condition. Although, it usually does not affect the development of visual function, entities like macular haemorrhages may lead to amblyopia causing deterioration of visual function. Such scenario leads to downgrade in quality of life of the affected child. Objective To explore the underlying clinical factors associated with retinal haemorrhage in term new-borns. Method A cross sectional study was conducted involving 136 term neonates admitted in the neonatal intensive care unit of Dhulikhel Hospital. Fundus examination was performed within 2 weeks of delivery. Retinal haemorrhage was graded according to their location in three retinal zones. Result Out of 136 cases examined, 44 (32.35%) of the cases had one of the eyes with retinal haemorrhage. Where grade 1 retinal haemorrhage was accounted in majority of the cases. Birth weight, gestational age, mode of delivery, poor Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) Score in 1 and 5 minutes, birth asphyxia, neonatal sepsis and heavy work in antenatal period had statistically significant correlation with occurrence of retinal haemorrhage. Conclusion Our results suggest that spontaneous vaginal delivery, larger birth weight, higher gestational age, birth asphyxia, low Appearance, Pulse, Grimace, Activity, and Respiration score, are risk factors for occurrence of neonatal retinal haemorrhage. It is recommended that in neonates with above high-risk factors should undergo targeted fundus screening for early identification and needful interventions.

Background Since glaucoma-related blindness may only be prevented with early identification and treatment, finding asymptomatic individuals in the target population is critical. It is thus important to determine the awareness and knowledge on glaucoma. Objective To determine the knowledge and awareness on glaucoma among the staff of a tertiary level hospital in central Nepal. Method This was a cross sectional study among the staffs of Dhulikhel Hospital who participated voluntarily in the study. The data was collected through the administration of semi-structured questionnaires. R version 4.0.3 (2020-10-10) was used for the data analysis. Categorical variables are presented as frequency (percentages) and the numerical ones are presented as mean (standard deviation). Adjusted odds ratio (AOR) with 95% confidence interval were estimated through logistic regression analysis for determining factors associated with awareness and knowledge of glaucoma. Result A total of 107 (89.2%) participants had heard about glaucoma of which 93 (86.9%) had good knowledge and 14(13.1%) had poor knowledge on glaucoma. The mean score of knowledge was 64.1±16.9. Only 47.7% of the participants said that glaucoma also has an asymptomatic course. We could not find an association of awareness and knowledge of glaucoma with any of the selected sociodemographic variables. Conclusion Although there was a fairly good glaucoma related awareness and knowledge among hospital staff, we found lack of understanding on some critical issues on glaucoma, mainly related to its asymptomatic nature. There is thus room for improvement in educating about glaucoma even in healthcare settings. Given the necessity of expanding glaucoma awareness in the public, hospital staff might potentially serve as messengers to the communities.

Background Diabetes mellitus is considered as a major public health concern globally. Poor management of diabetes may lead to several serious complications including endstage renal disease, diabetic retinopathy, diabetic neuropathy, and cardiovascular complications. Among them diabetic retinopathy is one of the leading causes of visual impairment and blindness in Nepal. Objective To assess the demographics and level of awareness among individuals with diabetes about diabetic retinopathy during their visit to Department of Ophthalmology at Dhulikhel Hospital. Method A descriptive cross-sectional study was conducted involving all consecutive cases of diabetes mellitus who attended eye clinic with the principal investigator and co-investigator from March 2021 to August 2021. Detailed demographics of the participants, their level of awareness regarding diabetic retinopathy and associated complications were documented. This was followed by a detailed ocular examination intending to screen for the presence of features of diabetic retinopathy. Result A total of 260 patients with a mean age of 54 years ± 12.20 (range of 24 - 85 years) were included. The male to female ratio was 2.2:1. Among them, 65.4% of the patients had diabetes mellitus for less than 5 years duration. Diabetic retinopathy was found in 18.46% of the cases. Awareness of diabetic ocular complications was significantly higher among literate population (p = 0.054), among those who have positive family history of diabetes mellitus (p = 0.529) and those who had undergone prior fundus evaluation (p = 0.000). Conclusion From result of this study, we can emphasize that there is a necessity for health education in order to increase the awareness and knowledge about diabetic retinopathy to lower the burden of sight threatening complications related with the issue.

Background Medical students spend long time in academic activities that increases the risk of developing refractive errors and dry eyes that can affect their learning and social abilities. Only a few studies are available regarding ocular problems and its contribution to visual impairment among medical students in Nepal. Objective To evaluate the ocular problems among the medical students in a University hospital. Method An observational, descriptive, cross-sectional study was conducted among five batches undergraduate medical students until 2022 of Kathmandu University School of Medical Sciences, Dhulikhel, Kavre. A self-administered questionnaire was used to obtain demographic data and information on visual problems followed by a detailed ocular examination that included refraction, color vision and Schirmer test. Result Total of 284 medical students (with 568 eyes) with mean age of 22.8 years, 179 males and 105 females were enrolled. Among them, 270 (47.5%) eyes were emmetropic. Simple Myopia was the commonest followed by Compound Myopic Astigmatism. The mean spherical equivalent in right and left eye were -0.914 ± 1.54 and -0.886 ± 1.53 respectively. Approximately 18% students had some form of dry eye. Nineteen students (6.7%) had color vision deficiency and 13 (4.6%) had deuteranomalia, 3(1.1%) had deuteranopia and 3(1.1%) had protanomalia. Conclusion Eye defects, like refractive errors, dry eyes and color blindness, are common among medical students. They need to be advised for frequent eye check up in order to diagnose eye defects timely and arrest visual impairment at early stage.

Methemoglobinemia is a potentially fatal condition if left untreated. Conventional treatment of nitrobenzene induced methemoglobinemia dictates the use of methylene blue, which is the antidote of choice. However, its availability in our setting is limited only to the laboratory use. We present a case of a 21-year-old female with intentional ingestion of nitrobenzene. Clinical history and supportive investigations revealed methemoglobinemia and it was successfully managed with single volume exchange transfusions in absence of specific antidote. While exchange transfusions are indicated for severe cases, it may be useful as an alternative treatment in acute life-threatening conditions where methylene blue is not available.

Background Rickettsial infection is an emerging neglected tropical disease in the Southeast Asia. In past few years Nepal is also reporting escalating prevalence of rickettsia. The under evaluation is resulting it as undiagnosed or are simply labeled as pyrexia of unknown origin. Objective To find out the prevalence of rickettsia in a hospital setting, assess the sociodemographic and other relevant clinical features of the rickettsia patients. Method This is a hospital based retrospective cross-sectional study from October 2020 to October 2021. This study reviewed the medical records of the department. Result The study included 105 eligible patients and the prevalence rate was 4.38 per 100 patients. The mean age of the participants was 42 years, and the mean hospital stay was 3 (SD ±2.06) days. More than 55% of the participants had fever for less than or equal to 5 days and 9% had Eschar present. Vomiting, headache, and myalgia were the most common symptoms and hypertension, and diabetes were the common comorbidities. Pneumonia and the acute kidney injury were the two complications of the patients as stated in the study. The severity of the thrombocytopenia deducted from admission time to discharge, and the case fatality was 4%. Conclusion The future studies shall consider on collaborative clinical and entomological research. This would help in better understanding of the etiology of supposedly unknown febrile illness and the under-investigated field of emerging rickettsia in Nepal.

SETTING: Tribhuvan University Teaching Tertiary Care Hospital, Kathmandu, Nepal, May-October 2019. OBJECTIVE: 1) To describe the bacteriological profile, 2) to identify the antimicrobial resistance (AMR) pattern, and 3) to find the demographic characteristics associated with the presence of bacterial growth and multidrug resistance (MDR) in adult urine samples undergoing culture and drug susceptibility testing. DESIGN: This was a hospital-based, cross-sectional study using routine laboratory records. RESULTS: Among 11,776 urine samples, 16% (1,865/11,776) were culture-positive, predominantly caused by Escherichia coli (1,159/1,865; 62%). We found a high prevalence of resistance to at least one antibiotic (1,573/1,865; 84%) and MDR (1,000/1,865; 54%). Resistance to commonly used antibiotics for urinary tract infections (UTIs) such as ceftazidime, levofloxacin, cefepime and ampicillin was high. Patients aged ⩾60 years (adjusted prevalence ratio [aPR] 1.6, 95% CI 1.4-1.7) were more likely to have culture positivity. Patients with age ⩾45 years (45-59 years: aPR 1.5, 95% CI 1.3-1.7; ⩾60 years: aPR 1.4, 95% CI 1.2-1.6), male sex (aPR 1.3, 95% CI 1.2-1.5) and from inpatient settings (aPR 1.4, 95% CI 1.2-1.7) had significantly higher prevalence of MDR. CONCLUSION: Urine samples from a tertiary hospital showed high prevalence of E. coli and MDR to routinely used antibiotics, especially among inpatients. Regular surveillance and application of updated antibiograms are crucial to monitor the AMR situation in Nepal.
LIEU: Hôpital universitaire de soins tertiaires de Tribhuvan, Katmandu, Népal, maioctobre 2019. OBJECTIF: 1) Décrire le profil bactériologique, 2) identifier le profil de résistance antimicrobienne (AMR), et 3) identifier les caractéristiques démographiques associées à la présence de croissance bactérienne et de résistance à plusieurs médicaments (MDR) dans les échantillons urinaires d'adultes mis en culture et testés pour sensibilité aux médicaments. MÉTHODE: Il s'agissait d'une étude transversale hospitalière réalisée en utilisant les dossiers de laboratoire de routine. RÉSULTATS: Parmi 11 776 échantillons urinaires, 16% (1 865/11 776) étaient positifs par culture, principalement à Escherichia coli (1 159/1 865 ; 62%). Nous avons observé une prévalence élevée de résistance à au moins un antibiotique (1 573/1 865 ; 84%) et de MDR (1 000/1 865 ; 54%). La résistance aux antibiotiques fréquemment utilisés dans le traitement des infections urinaires (UTI), comme la ceftazidime, la lévofloxacine, la céfépime et l'ampicilline était élevée. Les patients âgés ⩾ 60 ans (ratio de prévalence ajusté [aPR] 1,6 ; IC 95% 1,41,7) étaient plus susceptibles d'avoir une culture positive. Les patients âgés de ⩾ 45 ans (4559 ans : aPR 1,5 ; IC 95% 1,31,7 ; ⩾ 60 ans : aPR 1,4 ; IC 95% 1,21,6), les hommes (aPR 1,3 ; IC 95% 1,21,5) et les patients hospitalisés (aPR 1,4 ; IC 95% 1,21,7) avaient une prévalence significativement plus élevée de MDR. CONCLUSION: Les échantillons urinaires d'un hôpital tertiaire étaient associés à une prévalence élevée d'E. coli et de MDR aux antibiotiques utilisés en routine, notamment chez les patients hospitalisés. Une surveillance régulière et l'utilisation d'antibiogrammes à jour sont essentielles au suivi de l'AMR au Népal.
RESUMO
SETTING: Patan Hospital, Lalitpur, Nepal. OBJECTIVES: To describe 1) the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) and its antibiotic sensitivity pattern; 2) the demographic and clinical characteristics associated with MRSA infections; and 3) the treatment outcomes of in-patients with MRSA infection among patients with S. aureus infection between January 2018 and December 2020. DESIGN: This was a cross-sectional study using electronic and paper-based hospital records of patients with S. aureus infection. RESULTS: Of the 1,804 patients with S. aureus infection, 1,027 patients (57%, 95% CI 55-59) had MRSA. The MRSA were susceptible to vancomycin (100%), linezolid (96%), doxycycline (96%), chloramphenicol (86%) and cotrimoxazole (70%), and resistant to erythromycin (68%), clindamycin (56%), gentamycin (58%), ciprofloxacin (92%) and ofloxacin (91%). The prevalence of MRSA was higher in 2019, among out-patients, and in respiratory samples, and lower in blood samples. Of the 142 in-patients with MRSA, 93% had a successful clinical outcome (cured/improved). CONCLUSION: More than 50% of patients with S. aureus infection had MRSA that were resistant to commonly available antibiotics. This calls for strengthening surveil-lance and good infection control practices in this hospital.
LIEU: Hôpital de Patan, Lalitpur, Népal. OBJECTIFS: Décrire 1) la prévalence de Staphylococcus aureus résistant à la méticilline (MRSA) et son profil de sensibilité aux antibiotiques ; 2) les caractéristiques démographiques et cliniques associées aux infections à MRSA ; et 3) les résultats thérapeutiques des patients hospitalisés atteints d'infection à MRSA parmi ceux atteints d'infection à S. aureus de janvier 2018 à décembre 2020. MÉTHODE: Il s'agissait d'une étude transversale réalisée en utilisant les dossiers hospitaliers électroniques et papiers des patients atteints d'infection à S. aureus. RÉSULTATS: Sur les 1 804 patients atteints d'infection à S. aureus, 1 027 patients (57%, IC 95% 55-59) avaient un MRSA. Les MRSA étaient susceptibles à la vancomycine (100%), au linézolide (96%), à la doxycycline (96%), au chloramphénicol (86%) et au co-trimoxazole (70%), et résistants à l'érythromycine (68%), la clindamycine (56%), la gentamycine (58%), la ciprofloxacine (92%) et l'ofloxacine (91%). La prévalence des MRSA était plus élevée en 2019, parmi les patients ambulatoires, ainsi que dans les échantillons respiratoires. Elle était plus faible dans les échantillons sanguins. Sur les 142 patients hospitalisés avec MRSA, 93% ont connu un résultat clinique favorable (guérison/amélioration de l'état). CONCLUSION: Plus de 50% des patients atteints d'infection à S. aureus avaient un MRSA résistant aux antibiotiques habituellement disponibles. La surveillance et les pratiques de contrôle des infections doivent donc être renforcées dans cet hôpital.
RESUMO
SETTING: Tribhuvan University Teaching Hospital, Kathmandu, Nepal. OBJECTIVES: 1) To report the number and proportion of Pseudomonas, Acinetobacter, Burkholderia, Stenotrophomonas (PABS) species among intensive care unit (ICU) patients with sputum culture; and 2) to assess antimicrobial resistance patterns, demographic and clinical characteristics associated with resistance to at least one antibiotic and ICU discharge outcomes among those patients with PABS species admitted to hospital between 14 April 2018 and 13 April 2019. DESIGN: This was a hospital-based, cross-sectional study using secondary data. RESULTS: Of 166 who underwent sputum culture, 104 (63%) had bacterial growth, of which, 67 (64%) showed PABS species. Of the positive cultures, Pseudomonas, Acinetobacter, Burkholderia and Stenotrophomonas were present in respectively 32 (30.7%), 31 (29.8%), 1 (1%) and 3 (2.8%). Pseudomonas showed a high level of resistance to levofloxacin (61%), cefepime (50%) and amikacin (50%). Acinetobacter was largely resistant to cefepime (95%), imipenem (92%) and levofloxacin (86%). Of the 67 with PABS infection, 32 (48%) died. CONCLUSION: The study showed a high prevalence of Pseudomonas and Acinetobacter and the emergence of Stenotrophomonas in sputum culture samples of ICU patients. This highlights the need for monitoring PABS and associated resistance patterns to reduce mortality in ICU patients.

OBJECTIFS: 1) Rapporter le nombre et le pourcentage d'espèces de Pseudomonas, Acinetobacter, Burkholderia et Stenotrophomonas (PABS) parmi les patients admis en soins intensifs (ICU) avec culture d'expectorations ; et 2) évaluer les profils de résistance antimicrobienne, les caractéristiques démographiques et cliniques associées à la résistance à au moins un antibiotique et le devenir des patients après un séjour en ICU parmi ceux infectés par une espèce PABS admis à l'hôpital entre le 14 avril 2018 et le 13 avril 2019. MÉTHODE: Étude transversale hospitalière réalisée en utilisant des données secondaires. RÉSULTATS: Sur 166 patients dont les échantillons d'expectorations ont été mis en culture, 104 (63%) présentaient une croissance bactérienne dont 67 (64%) étaient associées à la présence d'espèces PABS. Parmi les cultures positives, PABS étaient présents dans respectivement 32 (30,7%), 31 (29,8%), une (1%) et trois (2,8%) cultures. Pseudomonas a été associé à un niveau de résistance élevé à la lévofloxacine (61%), à la céfépime (50%) et à l'amikacine (50%). Acinetobacter était majoritairement résistant à la céfépime (95%), à l'imipénème (92%) et à la lévofloxacine (86%). Sur les 67 patients présentant une infection à PABS, 32 (48%) sont décédés. CONCLUSION: L'étude a montré une forte prévalence de Pseudomonas et Acinetobacter, ainsi que l'émergence de Stenotrophomonas dans les échantillons de culture d'expectorations des patients admis en ICU. Cela souligne le besoin de suivi des espèces PABS et des profils de résistance associés afin de réduire la mortalité des patients admis en ICU.
RESUMO
Background This study focuses on experience of laparoscopic surgery at Shahid Dharma Bhakta National Transplant Centre (SDNTC), Nepal; which could enable us to gain knowledge regarding its benefits over conventional surgery. The present study revealed the frequency of various forms of laparoscopic surgeries done at our centre. Moreover, this study accomplishes laparoscopic donor nephrectomy "a historical milestone achieved in Nepal for kidney transplantation on 18th November 2018" which was the first Laparoscopic donor nephrectomy done in Nepal by Nepalese team. Objective The present study assesses the feasibility and safety of laparoscopic surgery at government hospital of Nepal. Method This hospital based cross-sectional study included all patients of age group 10 to 60 years, coming to outpatient department of SDNTC and those having indications for nephrectomy. We excluded patient having previous history of open surgeries of kidney, bleeding disorders, uncontrolled Diabetes Mellitus and uncontrolled Hypertension. The study duration was 15 months from November 2017 to January 2019. The total number of patients enrolled in the study was fifty where transperitoneal laparoscopic surgery was performed in all 50 patients. The demographic data, indications for surgery, duration of surgery, complications of surgery and perioperative outcomes were analyzed. Result Out of 50 cases, 34 (68%) underwent simple lap nephrectomy, 6 (12%) were lap pyeloplasty, 6 (12%) lap nephrectomy along with ureterectomy of long segment of diseased ureter, 1 (2%) lap radical nephrectomy, 1 (2%) lap donor nephrectomy for kidney transplantation, 1 (2%) lap heminephrectomy and 1 (2%) lap nephrectomy for hydronephrotic non functioning left crossed ectopia. Amongst all nephrectomies, 27 (54%) patients were operated on right side while 23 (46%) patients on left. The median age of the patient was 38.56 years. Out of total cases 32 (64%) were male and 18 (36%) female. The median operative time and hospital stay was 122.3 minutes and 5 days respectively. The median estimated blood loss was 74.1 cc. Only one patient required blood transfusion intra-operatively. 2 (4%) patients were converted to open surgery. Conclusion Laparoscopic surgery is feasible and safe procedure in government setup hospital with less cumbersome procedure and minimum complications associated with it.

Background In management of patients with traumatic brain injury, intracranial pressure holds an important place. Any untoward rise in intracranial pressure portends dreaded complications. Hence, any delay in detecting the issue is considered unacceptable. Objective This study focuses on analyzing the correlation between ultrasound derived optic nerve sheath diameter and intracranial pressure values derived from invasive intracranial pressure monitoring system in a neurosurgical patient with severe traumatic brain injury. Method A prospective observational study was performed using a convenience sample technique including all adult patients with traumatic brain injury who had invasive intracranial monitors placed as part of their clinical care. Ocular ultrasound was performed with 5 - 7.5 MHz linear probe of ACUSON X300 ultrasound system while simultaneous intracranial pressure readings were obtained directly from an invasive intracranial pressure monitoring system. The association between optic nerve sheath diameter and invasive intracranial pressure reading was assessed with the Pearson's correlation coefficient and a receiver operator characteristic curve was created to determine the optimal optic nerve sheath diameter cutoff to detect intracranial pressure > 15 cm H2O. Result One hundred and fifteen ocular ultrasounds were performed on 30 individual patients. The mean age of the population involved in this study is 42.13 years ± 1.89 with male preponderance in the ratio of 6:1. Pearson's correlation coefficient of optic nerve sheath diameter and intracranial pressure was found to be 0.844 (p < 0.000) demonstrating a significant positive correlation. The area under the receiver operating characteristic curve was found to be 0.961 (95% confidence interval = 0.93 to 0.99). Based on analysis of the receiver operating characteristic curve, optic nerve sheath diameter > 4.85 mm performed best to detect intracranial pressure > 15 cm H2 O with a sensitivity of 93.5% and specificity of 83%. Conclusion Optic nerve sheath diameter is a dependable screening tool to evaluate for elevated intracranial pressure among patients with traumatic nerve injury.

Background The coronavirus disease (COVID-19) pandemic has brought life to a standstill across the world, with nearly 178 countries reporting school closures. As the schools have started reopening slowly, precautions are utmost necessary to prevent the potential spread of COVID-19 in school and community settings. Objective To assess knowledge, attitude and practice towards COVID-19 among private school teachers. Method A web based cross-sectional analytical study design was undertaken. Currently working private school teachers of Chitwan District were included as a unit of analysis. The snowball sampling technique was employed to identify the eligible participant. Collected data was entered in SPSS version 20 and analyzed using the Chi-square test, Pearson correlation, and binary logistic regression. Result Of 344 participants, the majority were male (52.9%), most of the participants were from age group 26-30 years (38.4%). Regarding knowledge, attitude and practice, 57% had good knowledge, 53.2% had favorable attitude and 51.7% had good practice towards COVID-19. Logistic regression analysis demonstrated gender (OR 0.475, 95% CI: 0.256-0.818) and COVID-19 training (OR 25.687, 95% CI 5.354-123.226) were significant with good knowledge. Conclusion Knowledge about COVID-19 among private schools teacher was good, attitudes have been mostly favorable, and the practices were mostly adequate. However, good knowledge is not the only factor for better attitude and good practices. It is necessary to implement massive education campaigns, trainings and information via school authorities and health authorities by developing and adopting appropriate guidelines on COVID-19.

Digital subtraction angiography (DSA) has been a fluoroscopic golden investigative tool to know the vascular angiography of the brain and spinal cord. The technique in performing this procedure exposes residents in accessing the major vessels, branches of the arch of aorta, selective angiography and diagnosing different vascular anomalies of brain and spine. They are also exposed to the knowledge of different diagnostic catheters, its manipulation, use of dye and radiation exposure and safety. We would like to share our experience in training and disseminating the knowledge of digital subtraction angiography to the residents.

Background Closed method of pneumoperitoneum using Veress needle is an established technique. Classical closed technique is popular. Simple technique is a modified closed technique. Objective To compare the classical and simple techniques of closed pneumoperitoneum. Method This study was conducted in the department of urology, Bir hospital from August 1st 2019 to March 30th 2021. Total 114 patients were randomized into simple and classical technique of creating closed pneumoperitoneum. Time taken for creation of pneumoperitoneum, complications and failure of creating pneumoperitoneum in each group noted and analyzed. Chi square test, Fischer exact test and student t test were used and p < 0.05 considered significant. Result Among 114 patients, 61 in simple and 53 in classical technique allocated. In simple technique, mean age was 42.98±18.21 years, BMI was 21.84±2.57 kg/m2 , mean time for pneumoperitoneum creation was 108.07±21.14 seconds. In classical technique, mean age was 40.15±17.58 years, BMI was 21.94±2.54 (kg/m2 ), mean time for pneumoperitoneum creation was 189.70±32.21 seconds. Mean time was less in simple technique than classical technique (p < 0.001). Complication rate observed was 6% in each technique (p=0.797) with cumulative rate of 10%. Omental injury was seen in 3.2% in simple technique and 5.6% in classical technique (p=0.662). Retroperitoneal insufflation was seen in 6.5% in simple technique and 5.6% in classical technique (p=0.842). No failed pneumoperitoneum was observed in both groups. Conclusion Simple technique is as effective, reproducible and safe method as classical technique of creating closed pneumoperitoneum.

Background Childhood blindness and visual impairments could lead to the onset of blindness among children and adolescents. New cases appear particularly between the ages of 6-15 years and if uncorrected, runs a risk of developing Amblyopia, strabismus. There exists a mounting need to strengthen and modify established school eye health programs in Nepal as per the local needs and conditions. Objective To determine the prevalence of refractive error and ocular pathologies among school children in rural Nepal. Method This cross-sectional study was conducted in nine schools of Kavrepalanchowk and Bhaktapur district with 953 students screened from December 2018 to February 2020. The team of optometrist, ophthalmic assistants and ophthalmologist applied a standard protocol for screening of refractive error as a part of the school eye program of Dhulikhel Hospital. Other standard eye examinations were performed to note the ocular pathologies. The association of socio-demographic factors of students having refractive errors with that in emmetropes was identified using logistic regression analysis. Result A total of 953 students were screened in nine study sites, age ranged from 5-19 years. There were 183 students (19.2%) with refractive errors. Blurred vision was the common complaint reported by 2.5% of students. Multivariate logistic regression analysis showed higher age group children (aOR=2.93; 95% CI: 1.62-5.29; P=0.01) and urban area children (aOR=4.37; 95% CI: 0.87-21.98; P=0.07) to have higher odds of refractive error. Conclusion Refractive error is the major eye problem among school children. Despite its high prevalence, there is still a major gap in timely diagnosis and treatment. Regular vision screening and timely treatment is required for better addressing refractive error among school-going children.
