Abstract
Bacteria commonly adhere to surfaces and produce polymeric material to encase the attached cells to form communities called biofilms. Within these biofilms, bacteria can appear to be many times more resistant to antibiotics or disinfectants. This systematic review explores the prevalence and microbial profile associated with biofilm production of bacteria isolated from endotracheal tubes and its associations with antimicrobial resistance. A comprehensive search was performed on databases PubMed, Embase, and Google Scholar for relevant articles published between 1st January 2000 and 31st December 2022. The relevant articles were exported to Mendeley Desktop 1.19.8 and screened by title and abstract, followed by full text screening based on the eligibility criteria of the study. Quality assessment of the studies was performed using the Newcastle-Ottawa Scale (NOS) customized for cross-sectional studies. Furthermore, the prevalence of antimicrobial resistance in biofilm-producers isolated from endotracheal tube specimens was investigated. Twenty studies encompassing 981 endotracheal tubes met the eligibility criteria. Pseudomonas spp. and Acinetobacter spp. were predominant isolates among the biofilm producers. These biofilms provided strong resistance against commonly used antibiotics. The highest resistance rate observed in Pseudomonas spp. was against fluoroquinolones whereas the least resistance was seen against piperacillin-tazobactam. A similar trend of susceptibility was observed in Acinetobacter spp. with a very high resistance rate against fluoroquinolones, third-generation cephalosporins and carbapenems. In conclusion, endotracheal tubes were associated with colonization by biofilm forming bacteria with varying levels of antimicrobial resistance. Biofilms may promote the occurrence of recalcitrant infections in endotracheal tubes which need to be managed with appropriate protocols and antimicrobial stewardship. Research focus should shift towards meticulous exploration of biofilm-associated infections to improve detection and management.

Abstract
Obstructive sialadenitis of submandibular gland is commonly due to sialoliths and strictures in the Wharton's duct. Other endogenous pathologies include mucous plugs and polyps. Foreign bodies of Wharton's duct and submandibular gland are rare. Retrograde migration of foreign bodies via ductal orifice, traversing the ductal system to its final intraglandular location is an even rare entity. These often present with painful swelling of the gland and at times with a purulent sialitis. Diagnostic modalities include plain radiography, ultrasonography, sialography, as well as computed tomography and magnetic resonance imaging. Treatment includes antibiotics, incision and drainage of abscess, and removal of foreign body either surgically (intra-oral approach or sialadenectomy) or more recently via sialoendoscopy. This is a case report of 30 years male with accidental cannulation of Wharton's duct with grass that eventually got lodged in the deep lobe of the gland, and was managed with sialadenectomy.

Abstract
Background The nationwide lockdown was imposed upon by the Government of Nepal with regards to the COVID-19 pandemic. Even during times of limited mobility and travel, trauma cases were presenting to the hospital. Objective To asses trauma patterns among patients presented to the Emergency department in Dhulikhel hospital during the lockdown period. The assessment of the burden of trauma during the pandemic could aid in planning allocation of resources and improving trauma care. Method A retrospective cross-sectional study design was used to assess all patients with a history of trauma during the period of lockdown announced by the Government of Nepal for COVID-19 from March 24 to June 14, 2020. Result Among 2097 patients that visited the emergency department, 23% were trauma cases. In comparison to the corresponding time-period in 2019, trauma cases reduced by more than half (54.5%). The majority of patients utilized ambulances as a means of transportation; a few patients utilized Dhulikhel emergency medical services. The most common mechanism of injury was fall injury, followed by motor vehicle accident and physical assault. Traumatic brain injury occurred in 30% of patients. Of all patients, 71% were discharged after initial treatment, 26% were admitted to different wards and 3% were referred to other health centres. Conclusion Fall injury is a crucial public health concern followed by motor vehicle accident among trauma patients even during the pandemic condition. Thus, emergency rooms should aid in planning for preparedness, mitigation of trauma during situations like these, in planning the allocation of resources and improving trauma care.

Abstract
Accidental consumption of foreign body is a common presenting complain among patients especially in young age group. Majority of patients can be discharged safely after reassurance while a fraction of patient requires observation and further management. Here we report a case of a 35-year-old gentleman who presented to the out-patient department of our hospital in June 2021 for accidental ingestion of toothbrush. After detailed history and physical examination upper gastrointestinal endoscopy was planned for the patient. Failed endoscopic removal was considered the indication for surgery. A supraumbilical midline incision was used to remove the toothbrush. Following the surgical removal, he was managed conservatively and was discharged without significant complications. We describe this case in detail in addition to reviewing the pertinent literature.

Abstract
Background Obstructive sleep apnea is a highly prevalent yet largely under-diagnosed disease that poses a significant burden on the healthcare system. Objective To determine the role of predictors for Obstructive sleep apnea syndrome and its severity in Nepalese population. Method Prospective and analytical study conducted in the Department of Otorhinolaryngology and Head and Neck surgery at Kathmandu University Hospital between March 2018 and June 2020. A total of 85 adult patients with Obstructive sleep apnea with an Epworth sleepiness score greater than 10 were included. Overnight polysomnography was done and scoring of sleep associated events were done according to the American Academy of Sleep Medicine criteria. Participants were classified as simple snoring and mild, moderate or severe Obstructive sleep apnea syndrome groups depending on the Apnea Hypopnea Index values. Relationship of Apnea hypopnea index was analyzed with age, neck circumference, body mass index and Epworth Sleepiness score. Result Simple snoring was seen in 18(21.17%) patients, 14(16.47%) had mild Obstructive sleep apnea, 13(15.29%) had moderate Obstructive sleep apnea, whereas the severe group consisted of 40(47.05%) patients. The minimum Epworth Sleepiness Score was 10 and the maximum was 25. The Apnea hypopnea index correlated positively with Body mass index (p=.010) and Epworth sleepiness score (p <.001). However, Apnea hypopnea index had no association with age (p=.437) and neck circumference (p=.118). Conclusion Health professionals need to be extremely vigilant while examining patients presenting with Obstructive Sleep Apnea. Polysomnography is the investigation of choice in the early identification of this treatable disease.

Abstract
Background The first step in laparoscopic surgery is to establish the pneumoperitoneum for which many approaches have been introduced to minimize the complications. Although controversies exist regarding the most efficient technique, till now the best entry technique is still unsettled. Objective To compare the safety, operating time and outcome of Direct Trocar Insertion with a well-established and widely practised Open Access Technique. Method This is a prospective study at Nobel Medical College Teaching Hospital from November 2019 to February 2021. Patients were grouped into either of the two groups, Group 1 for Direct Trocar Insertion and Group 2 for Open Access Technique. They were later analysed for major and minor complications of the technique and a comparison of either method was done at the end of the study period. Result A total of 823 patients were enrolled in the study. Among the study population, 411 patients had Direct Trocar Insertion while 412 patients had Open Access Technique. The majority of the operation that was done during the study period was laparoscopic cholecystectomy. Patients in the Open Access Technique group experienced more complications compared to Direct Trocar Insertion group. Conclusion Despite the fear of adopting the Direct Trocar Insertion, this is a safe, better and quick technique for laparoscopic port entry. However, any surgeon practising laparoscopic surgery should be competent to adopt either technique to overcome failure in either process during port entry.

Abstract
Background Pilonidal sinus is commonly seen at the sacrococcygeal region and few other sites, usually located at the midline, at areas where hairs collect or near protuberances or some adjacent rubbing surfaces. Its presence elsewhere is uncommon. We share an interesting case of a recurrent discharging sinus from the cheek bulge of a male which turned out to be a pilonidal sinus containing tuft of hairs on exploration and wide excision. Case presentation A 37 years old hirsute male presents to us with a non-healing discharging sinus at the bulge of the cheek. Exploration after a course of antibiotics showed 2 subcutaneous cavities with tuft of hairs. The area was excised along with a margin, thorough irrigation and curettage was done and the wound was closed primarily; a Z-plasty was incorporated in the central part to break the resultant suture line. Histopathological examination was done to confirm the diagnosis and rule out an off-midline dermoid cyst or an underlying/coexisting malignancy. Post-operative course was uneventful. The patient has been recurrence free for 1.5 years and is satisfied with the nature of the scar. Conclusions Pilonidal sinus of the cheek bulge is an extremely rare entity. Complete excision and clinical suspicion are important for cure of this nagging ailment, especially at unexpected areas.

Abstract
Background Spinal anaesthesia is the current standard for caesarean section. Hypotension, a common complication, potentially results in adverse foetal and maternal outcomes. However, hypotension-defining criteria are varied. Objective To identify the blood pressure thresholds for spinal anaesthesia-induced hypotension during caesarean section. Method This is a retrospective cohort study of spinal anaesthesia-induced hypotension that occurred till baby-delivery during caesarean section. Reports on intraoperative hypotension, collected previously from January to December 2019, were reviewed to identify the hypotension-defining thresholds. The thresholds were categorized into systolic blood pressure (SBP) of 80, 90 or 100 mmHg, mean arterial pressure (MAP) of 60, 65 or 70 mmHg, combinations, and others. Parturient and anaesthesia characteristics, and associated hypotensive symptoms were also recorded for descriptive analysis. Result Spinal anaesthesia-induced hypotension was identified in 129 (11.5%) cases among 1116 caesarean sections. Altogether, 12 hypotension-defining thresholds were employed. Thresholds of SBP 90, MAP 60, and SBP 80 mmHg were used in 53 (41%), 28 (21.7%), and 21 (16.2%) cases respectively. Mean maternal age was 28 (±4.22) years and 87 (67.4%) cases underwent emergency surgery. Median sensory blockade level was T4. Nausea-vomiting, bradycardia, and tachycardia were associated during five (3.8%), six (4.6%), and 15 (11.6%) hypotensive incidents respectively. Two cases had unrecordable blood pressure but there was no maternal mortality. Conclusion Systolic blood pressure of 90 mmHg and mean arterial pressure of 60 mmHg included the most common thresholds for spinal anaesthesia-induced hypotension during caesarean section. Identifying the safe and clinically relevant hypotension-defining criteria needs further investigation.

Abstract
Abstract
Background
Initiation of breastfeeding within one hour from birth is one of the five key essential newborn care messages, implemented along with birth preparedness package since 2008. This study aimed to determine the trend of early initiation of breastfeeding (EIBF) and to assess the effect of health facility delivery on EIBF in Nepal.
Methods
We analyzed the data from the last four nationally representative Nepal Demographic and Health Surveys (NDHS) conducted in 2001,2006,2011 and 2016. Data on the early initiation of breastfeeding was obtained from the mothers of infants born within 24 months prior to the survey. The explanatory variable was the place of delivery, dichotomized as either the health facility, or home delivery. Survey year had a significant interaction with the place of delivery. Multivariable logistic regression was conducted separately on pooled samples before (NDHS 2001 and 2006) and after (NDHS 2011 and 2016) the program implementation. Adjusted odds ratio (AOR) with 95% confidence interval (CI) for EIBF was calculated after adjusting for predetermined covariates.
Results
The rate of EIBF increased by 26.5% points (from 32.8% in 2001 to 59.3% in 2016) among infants delivered in a health facility, compared to an increase by 17.1% points (from 29.9% to 47.0%) among home born infants. EIBF increased by 32.5% points before, compared to 49.7% points after BPP. Delivery in a health facility was associated with a higher odd of EIBF in later years (AOR2.3, 95% CI 2.0,2.8), but not in earlier years (AOR1.3, 95% CI 0.9,2.0). Delivery by caesarean section, first-born infant, and lack of maternal education were associated with a lower rate of EIBF in both periods.
Conclusions
Higher EIBF was associated with health facility delivery in Nepal, only after programmatic emphasis on essential newborn care messages. This implies the need for explicit focus on EIBF at birth, particularly when mother is less educated, primiparous or undergoing operative delivery.
Key messages
The rate of initiation of breastfeeding within an hour from birth is increasing in Nepal, with higher rates in health facility delivery, as shown by the recent four nationally representative surveys. Programmatic focus on essential newborn care messages may have contributed to significant association of higher rates of early initiation of breastfeeding when delivered in health facility.

Abstract
Abstract
Background
A history of child abuse is common and is associated with the later occurrence of risky health behaviors, mental disorders, and chronic conditions, strongly suggesting that child abuse may be associated with elevated mortality. However, most of the literature on child abuse has studied psychosocial/behavioral or medical outcomes and have not addressed mortality directly.
Methods
Data from the 2012 Canadian Community Health Survey, linked to the Canadian Vital Statistics Database, were used in the analysis. The CCHS-2012 interview (n = 19,830) retrospectively assessed childhood physical abuse, sexual abuse, and witnessing intimate partner violence before the age of 16. Each type of abuse was analyzed separately using Cox proportional hazards models for all-cause mortality. Hazard ratios (HR) and associated 95% confidence intervals (CI) were estimated with and without adjustment for covariates.
Results
An effect on mortality was observed among men for witnessing interpersonal violence (age-adjusted HR 2.47, 95% CI 1.48-4.12), and severe physical abuse (age-adjusted HR 2.3, 95% CI 1.21-4.36). In each case, the association was not significant for women; the age-adjusted HRs being 0.93 (95% CI: 0.51-1.70) and 0.59 (95%CI: 0.64-2.60) respectively. The association was seen only among those reporting frequent abuse ( > =10 times) and weakened (became not significant) with adjustment for covariates that may mediate the association such as smoking and chronic conditions.
Conclusions
As predicted by a broader literature on childhood adversity, child abuse increases the risk of mortality. The effect was significant for severe physical abuse in men, but imprecision due to a limited number of deaths may have rendered other associations non-significant. The study provides some degree of confirmation that child abuse contributes to later life mortality. Hence public health strategies that prevent child abuse and mitigate the harms of the mediators might prevent mortality.
Key messages
Witnessing intimate partner violence is just as harmful as actually experiencing physical abuse. Preventing children's exposure to violence in family is valuable in preventing mortality in adulthood. Enhancing child abuse prevention programs and mitigating the harmful effects of the mediators such as smoking, substance use, and chronic conditions is important in reducing mortality in adult life.

Abstract
Rhabdomyosarcoma comprises about half of the soft tissue tumors. Approximately 40% of the alveolar subtype occur in the head and neck region. Patients present with unilateral nasal mass with/without lymphadenopathy and with/without orbital manifestations. Diagnosis is aided radiologically by CT scan, MRI along with biopsy and is confirmed by immunohistochemistry. Treatment involves surgical resection, chemotherapy, radiotherapy or a combination of these. In spite of treatments, however, the outcome is poor. This is a case report of 14-year-old male who presented with unilateral nasal mass with proptosis of right eye who was eventually diagnosed as a case of alveolar rhabdomyosarcoma of solid variant.

Abstract
Although maggots are unanonymously linked to carcass or dead tissues, there are reports of its infestation into living tissues as well. Myiasis denotes maggot infestation in living tissue. There are two forms of myiasis namely obligate and facultative. Obligate myiasis denotes maggots feeding on living tissue whereas facultative myiasis represents the opportunistic behaviour of the fly taking advantage of wound or necrotic tissue, laying by eggs which hatch into maggots. Decreased physical activity and poor hygiene leads to maggot infestation. Maggot invasion of living tissues is undesirable occurrence which can best be avoided by improving hygiene. People with low living standards in the developing nations are the occasional victims for maggot infestations. We present cases of obligate myiasis for their uniqueness and rarity.

Abstract
Background Sympathetic arousal response due to rewarding emotion may not be considered threat to the well-being but such arousal response evoked by fear or punishment can be stressful. When such changes are recorded in lab as biological signals, induced with appropriate stimulus, the observed response may serve as a good indicator of homeostatic alteration. In this study, skin conductance was utilized to record sympathetic response for cognitive load, by application of simple subtraction task. Objective To detect sympathetic arousal by utilization of galvanic skin response during mental arithmetic task. Method Total of eighty two subjects, forty two female and forty male participated in the study. Twenty two subjects were provided mental task to record skin conductance. In sixty subjects, galvanic skin response, pulse rate, respiratory rate and temperature were recorded by appropriate transducers to obtain baseline and task response to detect differential recordings. Subjects performed the mental exercise of arithmetic task (MAT) with transducer placed in upper limbs. Mean of averages for respective variables were statistically calculated from obtained recordings. Result For measured galvanic skin response, 57 subjects showed increased skin conductance (rise in amplitude) whereas, 25 subjects had no rise in amplitude ("A peak") while performing the mental arithmetic task, when compared to control recording. However, in 20 subjects, pulse rate and respiratory rate showed significant rise though, the change in the skin conductance was not significant. Conclusion Galvanic skin response is useful for demonstration of sympathetic activation induced by simple mental subtraction task, and can be utilized along with vital parameters mentioned in this study to discuss in vivo variation that exist as differential for core and superficial sympathetic outflow among individuals.

Abstract
Introduction: Biliary communication of hepatic hydatosis is one of the important complications. It may be minor or major communication. Minor communication is usually diagnosed during operation by the presence of bile stained hydatid fluid on aspiration or bile leak during surgery. However, in major communication, patients present with obstructive jaundice, abdominal pain and cholangitis. Surgical management of major communication is difficult and is associated with high morbidity and mortality.Methods: This is a retrospective study at Tribhuvan University Teaching Hospital, Kathmandu, Nepal over a period of two year (April 15th 2012 to April 15th 2014) and analyzed the medical records of 30 patients admitted and treated for hydatid cyst of liver in surgical ward during that period. Demography, clinical features, management and outcome were analyzed.Results: Of 30 patients with hepatic hydatid cyst operated over a period of two years, thirteen patients had cystobiliary communication. Amongst them, five minor communications were diagnosed during operation and managed with suture plication and omentopexy. Out of the eight major communications, seven were diagnosed preoperatively and all had cholangitis, and one had hydatid cyst of gallbladder and was diagnosed intraoperatively. Among six cases of major communication, five cases required CBD exploration and bile duct reconstruction while partial cholecystectomy was done for hydatid cyst of gall bladder and one case was managed by ERCP sphincterotomy, evacuation of cyst content and stenting. one case was managed with pigtail drain as the patient had infected hydatid cyst and not fit for surgery.Conclusion: Cystobiliary communication is a common complication of hydatid cyst of liver. Therapeutic options are related to size and location of the cyst and size of communication.Journal of Society of Surgeons of Nepal Vol.17(1) 2014: 31-34

Abstract
Introduction: To observe how vacuum assisted venous drainage (VAVD) may influence the flow in a cardiopulmonary bypass circuit with different size of venous lines and cannulas.
Methods: The experimental circuit was assembled to represent the cardiopulmonary bypass circuit routinely used during cardiac surgery. Wall suction was applied directly, modulated and measured into the venous reservoir. The blood flow was measured with a flow-meter positioned on the venous line. The circuit prime volume was replaced with group O date expired re-suspended red cells and Plasmalyte 148 to a hematocrit of 28% to 30%.
Results: In an open circuit with gravity siphon venous drain, angled cannulae drain more than straight ones regardless the amount of suction applied to the venous line (16 Fr straight cannula (S) drains 90 ml/min less than a 16 Fr angled (A) with a siphon gravity). The same flow can be obtained with lower cannula size and higher suction (i.e. 12 A with and -30 mmHg). Tables have been created to list how the flow varies according to the size of the cannulas, the size of the venous tubes, and the amount of suction applied to the system.
Conclusions: Vacuum assisted venous drainage allows the use of smaller cannulae and venous lines to maintain a good venous return, which is very useful during minimally invasive approaches. The present study should be considered as a preliminary attempt to create a scientific-based starting point for a uniform the use of VAVD.

Abstract
Background: There has been a considerable increase in the numbers of older people in the world population of both developed and developing countries. These populations are thought to be at greater risk for depression. Many researches are conducted on physical wellbeing of elderly but studies regarding depression among elderly, especially in old age home is lesser in the developing countries. Objectives: To assess depression among elderly residing in an old age home in Kathmandu and its association with some of the socio-demographic variables. Methods: One hundred fifty elderly people residing in social welfare centre elderly home, Pashupatinath, Gaushala, Kathmandu, Nepal were selected randomly. Geriatric depression scale (GDS) was applied in all the individuals to assess the prevalence and degree of depression. Results: This study showed that, 47.33% of population had depression. Among the depressed population, 70.42% had mild depression and 29.58% had severe depression. There was significant association between the prevalence of depression and history of physical illness. Conclusion: Depressive disorder is highly prevalent among the elderly population residing in the old age home in Kathmandu with history of physical illness.

Abstract
INTRODUCTION Chronic dacryocystitis results in chronic infection and inflammation of the lacrimal sac. OBJECTIVE To identify the aetiology of chronic dacryocystitis and to determine their antimicrobial susceptibility pattern. MATERIALS AND METHODS A cross - sectional study was undertaken including 120 lacrimal swab materials collected from patients aged above 15 years suffering from chronic dacryocystitis. STATISTICS Data analysis was done by using software "Win pepi'' ver 7.9. RESULTS The bacteria of eight different species were isolated from 76.66 % (92/120) culture positive samples. 85.86 % showed a single and 14.13 % showed a mixed growth pattern. Coagulase negative staphylococci were the most common bacteria (P= 0.018) accounting for 33.96 % followed by Staphylococcus aureus (25.46 %), Streptococcus pneumoniae ( 19.81 % ), Streptococci viridans (5.66 %), Escherichia coli (5.66 %), Haemophilus spp ( 4.71 % ), Streptococcus pyogenes (3.77 %) and Bacillus spp (0.94 % ). Staphylococcus aureus were the most predominant bacteria in mixed growth. Rate of infection was higher in males 81.39 % than in females 74.02 %. Infection was higher in the age group of above 31 years. In the antimicrobial susceptibility test, except staphylococcus aureus, all the Gram positive isolates were 100 % sensitive to chloramphenicol and were least sensitive to tobramycin, but Gram negative isolates were equally sensitive to Chloramphenicol and Nalidixic acid. CONCLUSION Coagulase negative staphylococci are the most frequently isolated bacteria. Staphylococcus aureus is predominantly found in mixed growth. Chloramphenicol is the most effective drug of choice for chronic dacryocystitis.
