Diagnostic Accuracy of Drop Hydrogen Peroxide Test as a Novel Bedside Diagnostic Test to Differentiate Transudative and Exudative Pleural Effusion Against Light's Criteria.

Background Diagnostic evaluation of pleural fluid according to Light's criteria to differentiate between exudative and transudative fluid takes 1 or 2 working days. For rapid clinical management, especially in critically ill patients, a simpler bedside diagnostic test can be done which has similar diagnostic accuracy as that of Light's Criteria. Objective To determine the diagnostic accuracy of Drop Hydrogen Peroxide test to differentiate exudative and transudative pleural effusion in comparison to Light's criteria. Method A concurrent validity test was performed using a convenient sampling technique including patients presenting to the Department of Internal Medicine from January to September 2021, who had pleural effusion. Two milliliters of tapped pleural fluid of patients who underwent aseptic thoracocentesis was collected in a test tube to which one to two drops of 20% hydrogen peroxide was added. Presence of bubbles suggested an exudative type of fluid. Rest of the tapped pleural fluid was sent to the laboratory for further evaluation by Light's criteria, which was compared with the results by Drop Hydrogen Peroxide Test. Result There were 83 patients who had pleural effusion, of them a total of 43 patients had transudative pleural effusion while 40 patients had exudative pleural effusion based on Light's criteria and 37 patients had transudative pleural effusion while 46 patients had exudative pleural effusion based on drop hydrogen peroxide test. Conclusion The drop hydrogen peroxide test allows cost effective and prompt evaluation of the type of pleural effusion is exudative or transudative, thereby making it a convenient diagnostic bedside test.

Coronary Artery Disease in Nepal: Current Perspective, Challenges, Need for National Practice Guidelines, and Potential Solutions.

South Asians are estimated to have a 40% increased risk for coronary artery disease as compared to populations from other regions. Nepal, as a South Asian country, should also analyze the burden of coronary artery disease and its risk factors to minimize cardiovascular morbidity and mortality. We reviewed the barriers to cardiovascular care and its services in low- and middle-income countries, including Nepal. The identified barriers included coronary artery disease risk factors, access, cost, adherence to cardiovascular care, awareness, knowledge gaps, and socioeconomic and health system challenges. The possible strategies to reduce coronary artery disease included national, regional, and local perspectives. It also highlighted the involvement of community workers and local leaders, education, patient-centered intervention, easy access to drugs and treatments, rehabilitation and public health measures, innovation within the health care system, and multi-sectoral involvement. This review provides insights into the current situation of coronary artery disease and its possible solutions.

Comparative Study between the Use of Pigtail Catheters and Traditional Chest Tube Drain in Cases with Pneumothorax.

Background Pneumothorax is a condition in which air or other gas is present in the pleural cavity. Mainstay of management of pneumothorax is to remove the air from the pleural space usually done by chest tube insertion. There is still uncertainty whether minimal invasive management with pigtail catheter is sufficient for the management of pneumothorax. Objective To find the effectiveness, safety, tolerability, efficacy of pigtail catheters and large bore chest tubes. Method Prospective comparative study was done in Dhulikhel Hospital between August 2019 till August 2021. Chest tube insertion used to be the only available treatment modality till December 2020 (15 months). Following January 2021 after obtaining ethical clearance for use of pigtail insertion for pneumothorax, this treatment modality was done (8 months). Result Among 76 patients, 52(68.4%) underwent a large bore chest tube and 24 (34.6%) pigtail catheter patients. Mean age of the patients was 48 years (SD 18.01). Duration of hospital stay and length of hospital stay was more in large bore catheters and less in pigtail catheters. Eight hours post tube placement of the expansion of the lungs was present in pigtail and was statistically significant. Pain killer used in pigtail catheters was limited to Non-steroidal anti-inflammatory drugs, for large bore catheter opioids were added and were statistically significant. Conclusion Pigtail catheter is nearly effective as compared to traditional wide bore catheters.

Perception Regarding Care of Attempted Suicide Patients among Nursing Students in Kathmandu University School of Medical Sciences.

Background Suicide is an act of deliberately killing oneself. It is a global health problem and is the second leading cause of death in 15 to 29 years. Thus, studying nursing students' perception towards suicide attempters has paramount importance in understanding and addressing the existing gaps in healthcare delivery system. Objective To assess the nursing students' perception towards attempted suicide and to find out the association between perception and selected variables. Method A descriptive, cross sectional design was carried out to assess the nursing students' perception towards suicide attempters in Kathmandu University School of Medical Sciences. The respondents were 193 nursing students. A structured questionnaire was used in order to collect data. Descriptive statistics including frequency, percentage, mean and standard deviation were calculated to summarize the data and inferential statistics, Mann Whitney-U test was used for the association between perception and selected variables. Result A total 193 nursing students participated in this study. The scores between 1 and 2.4 were considered 'positive', 'unsure' or 'uncertain', between 2.5 and 3.4 and negative for 3.5 and above' over all nurses showed relatively negative perception towards suicide attempters. According to results from eight domains of perception, those who did not attend the courses on psychiatry nursing presented higher score, which was found to have significant association with permissiveness, unpredictability and incomprehensibility. A younger nursing student shows significant association with incomprehensibility. Younger nursing student showed statistically significant association with duration of suicide process. Conclusion Nursing students are frequently encountered with attempted suicide patients. Therefore, they must be aware of their attitudes toward this group of patients as part of their professional and therapeutic role. Thus a nurse's positive perception towards attempted suicide can play a key role in communicating and preventing a future suicide attempt.

Open Surgical Management of Abdominal Aortic Aneurysm at a Community Based University Hospital in Nepal.

Aortic aneurysms are abnormal dilatation of aorta. The risk factors include male sex, age > 65, smoking, coronary artery disease and hypertension. Here we report a case of infra-renal abdominal aortic aneurysm (AAA) of diameter 6 cm. The patient sucessfully underwent aorto-biiliac bypass surgery using Dacron Y graft. During abdominal aortic aneurysm surgery anesthetic challenge is also of paramount importance and should be considered.

Recovery Pattern in Different Surgical Approaches on Thoracic Enhanced Recovery based Fourteen-Step Protocol in Patients Undergoing Cardio-thoracic Surgery at University Hospital of Nepal.

Background Cardio-thoracic surgery involves open and minimally invasive techniques. Enhanced recovery after surgery is used for early recovery from surgery. Enhanced recovery after surgery decreases hospital stay duration. Patients undergoing Enhanced recovery after surgery after video assisted thoracic surgery use less pain killers and have less hospital cost. There has not been any study on outcomes on patient who follow physiotherapy protocol designed in our setting. Objective To find the physiotherapy outcomes in patients undergoing thoracic enhanced recovery after surgery (T-ERAS) based 14 step protocol locally designed at Dhulikhel Hospital, Kathmandu University Hospital (DH, KUH). Method This is a retrospective cross sectional observational study. All the cases who underwent cardiothoracic surgery were classified based on the approach of chest surgery performed into groups Sternotomy, Thoracotomy and Video Assisted Thoracic Surgery (VATS) groups. Patients were advised for Thoracic Enhanced recovery after surgery based on the protocol that has been devised at Dhulikhel Hospital. The recovery of patients based on activities they could perform was noted and analyzed. Result Both ICU stay and hospital stay in number of days were highest in thoracotomy (6.04 days) group while that was lowest in video assisted thoracic surgery group (1.67 days). There is a similar recovery until step 5, i.e. 2 days and rapid progression in further steps in video assisted thoracic surgery group while it is much slower in both sternotomy and thoracotomy groups. Conclusion Postoperative mobilization and physiotherapy enhance early healing and decrease hospital stay. Mean hospital stay and ICU stay were shorter for video assisted thoracic surgery cases compared to Thoracotomy and Sternotomy groups and the mean days to achieve different steps varied within the protocol between groups compared.

Prevalence of Exclusive Breast Feeding and its Associated Factors among Mothers.

Background Breast feeding is the priceless gift given by mother to her newborn. It also has benefits to both mothers and baby. Prevalence of exclusive breast feeding varies from 26.4% in one study to that of 82.2% in another study. Objective To assess the factors associated with exclusive breast feeding among mothers. Method A prospective cross-sectional study using systematic random sampling method, was carried out in Dhulikhel Municipality for two months in November and December 2017 after taking permission from KUSMS IRC and from Dhulikhel Municipality. The study sample was 218 mothers whose infants between 6 months to 1 year were included in the study. A structured and semi-structured interview schedule was used in order to collect the information. Descriptive statistics including frequency and percentage was calculated to summarize mothers' socio-demographic information. Chi-square test was used for non-parametric categorical data in order to find out the association between variables. P-value less than 0.05 were considered significant. Result The prevalence of exclusive breast feeding was 75.7% in the present study. Maternal age found to be varied from 17 years to 40 years. Maternal age, parity of mother and types of family found to be significantly associated with the practice of exclusive breast feeding (p < 0.05). Mothers' occupation and education level was not associated with the practice of exclusive breast feeding. Conclusion Majority of the mothers practice exclusive breast feeding (75.7%). Finding of this study i.e. the factors influencing the practice of exclusive breast feeding will help the health care workers to plan the community awareness program on it.

Prevalence and Associated Factors of Low Birth Weight among Newborns in a Tertiary Level Hospital in Nepal.

Background A United Nations Children's Fund reported that the global low birth weight was 15.5%, more than 95.6% of them being from developing countries. Low Birth Weight is a major factor associated with neonatal deaths in developing countries. Also, birth weight is one of the major factor in determining child survival, growth and development. Objective The objective of the study was to identify the prevalence and associated factors of low birth weight among newborns delivered in Dhulikhel Hospital. Method A cross sectional research design was carried out among all newborns delivered at the maternity ward of Dhulikhel Hospital within a period of one year. Data were collected using delivery record register as well as its electronic version which was available in the ward. The collected data were entered and analyzed using software SPSS 20 version with descriptive and inferential statistics. Result Total 2,798 numbers of newborns delivered in the hospital during the period of one year met the inclusion criteria for the study. Among them, 21.6% had low birth weight. We found that low birth weight of newborns was significantly affected by younger age of the mother and lesser weeks of gestation at birth. There were no significantly affected by antenatal clinic visit, parity, sex of the baby, type of delivery. Conclusion The study found that more than one fifth of babies had Low Birth Weight. The study findings suggest that special emphasis should be given to minimize early pregnancy to avoid low birth weight babies.

Rare case of combined vascular malformation of the face: a successful surgical management.

Combined vascular malformation affecting the facial region is an extremely rare clinical entity that is debilitating both functionally and emotionally. Treatment warrants a multidisciplinary approach with the aim of removing the vascular anomalies and ameliorating any functional facial disfigurement. Here, we present a case of a 40-year-old female with combined vascular malformation of the face who was treated successfully with surgical intervention accompanying significant resolution of facial disfigurement.

Descriptive epidemiology of rotavirus infection in a community in North India.

In India, rotavirus infections cause the death of 98621 children each year. In urban neighbourhoods in Delhi, children were followed up for 1 year to estimate the incidence of rotavirus gastroenteritis and common genotypes. Infants aged f1 week were enrolled in cohort 1 and infants aged 12 months (up to +14 days) in cohort 2. Fourteen percent (30/210) gastroenteritis episodes were positive for rotavirus. Incidence rates of rotavirus gastroenteritis episodes in the first and second year were 0.18 [95% confidence interval (CI) 0.10­0.27] and 0.14 (95% CI 0.07­0.21) episodes/child-year, respectively. The incidence rate of severe rotavirus gastroenteritis in the first year of life was 0.05 (95% CI 0.01­0.10) episodes/child-year. There were no cases in the second year. The common genotypes detected were G1P[8] (27%) and G9P[4] (23%). That severe rotavirus gastroenteritis is common in the first year of life is relevant for planning efficacy trials.

Predicting factors of patient satisfaction after varicose vein surgery at a university hospital in Nepal.

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.

A rare case of persistent lateral marginal vein of Servelle in Klippel Trenaunay Syndrome: A successful surgical management.

INTRODUCTION AND IMPORTANCE: Klippel-Trenaunay Syndrome (KTS) is a rare congenital vascular disorder characterized by capillary malformation, varicosities, and tissue overgrowth. It usually affects the unilateral lower extremities manifesting commonly as pain, localized rise of temperature, and venous tortuosity. However, in severe cases, ulceration, cellulitis, and chronic lymphatic malformation may be present. Management is mostly supportive and involves the use of compression stockings. CASE PRESENTATION: Here, we report a case of KTS with a persistent lateral marginal vein of Servelle managed with radiofrequency ablation along with sclerotherapy of selected perforators. On a two-year follow-up, the symptoms had resolved and Doppler ultrasonography revealed resolution of the defective vein along with the absence of incompetent perforators. CLINICAL DISCUSSION: In cases with venous malformation with the persistence of embryonic avalvular venous structures, like the lateral marginal vein of Servelle, surgical intervention is warranted especially at a younger age to reduce the risk of future thromboembolic events and recurrence. CONCLUSION: Varicosities of the lateral marginal vein of Servelle can be managed successfully by radiofrequency ablation and adjunct sclerotherapy in selected cases.

Case report of eventration of diaphragm due to an unknown febrile illness causing phrenic nerve palsy and other multiple nerve palsies.

INTRODUCTION: Diaphragmatic eventration can be congenital or acquired. Diagnosis is delayed due to no symptoms or very mild ones and is generally done by imaging modalities. This condition is managed by plication of the affected part of diaphragm by various surgical approaches. PRESENTATION OF CASE: A forty seven years lady presented with one year long history of abdominal pain, bloating and fullness after meals who was being treated in line of peptic acid disorder. She had developed bilateral foot drop after typhoid fever at seventeen years of age. Clinical examination and imaging with chest x-ray, chest ultrasound and computed tomography scan suggested eventration of left hemidiaphragm. Plication of eventration of left hemidiaphragm was done via mini thoracotomy of the left thorax. There were no postoperative complications and she was discharged on the sixth postoperative day. DISCUSSION: Acquired eventration of diaphragm is commonly due to traumatic phrenic nerve palsy but rarely can be associated with a history of infection causing nerve palsies. Thoracic ultrasound is an emerging modality for diagnosis supporting X-rays and CT Scans. Plication of eventration with minimally invasive techniques has less number of hospital stay and less pain compared to open approaches. CONCLUSION: Non-traumatic diaphragmatic eventration due to acquired phrenic nerve palsy following an unknown febrile illness is a rare case to be reported in Nepal. The aim of treatment is expansion of intra-thoracic space which is done by plication of the diaphragm.

Short Term Outcome of Adjunct Foam Sclerotherapy for Varicose Veins in Patients Subjected to RFA at Dhulikhel Hospital, Nepal.

BACKGROUND: Varicose veins are dilated, tortuous, superficial veins usually seen on lower limbs. Various surgical modalities are available for varicose veins including open surgery (Trendelenburg operation), Endovenous Laser Ablation (EVLA), Radiofrequency Ablation (RFA) and Sclerotherapy. The aim of this study is to look for the outcome of adjunct sclerotherapy for varicose veins done as an adjunct with Radio Frequency Ablation. OBJECTIVE: To know the possible outcome regarding benefits and complications of adjunct sclerotherapy with Radio Frequency Ablation. METHODOLOGY: We combined Radio Frequency Ablation of varicose veins with necessary phlebectomy and perforator ligation and performed adjunct sclerotherapy for residual significant varicosities with polidocanol (2%) mixed with 2 ml NS and 2 cc of air (Tessari method) to patients undergoing varicose vein surgery in between 2016 and 2017. Records on complications were enquired immediately following surgery and on 1st follow up done within 3-5 days of the procedure. RESULTS: Among 256 limbs subjected to varicose veins surgery 51 limbs were given adjunct sclerotherapy. Among them, five limbs had perivenous spillage with some localized swelling while there was allergic reaction in one patient as immediate postprocedural complication. Nine limbs had painful thrombosed veins during early follow-up. CONCLUSIONS: Adjunct sclerotherapy showed complication rate of roughly one tenth and one fifth of the treated cases in immediate and early postoperative follow-up.

A case of thymoma in myasthenia gravis: Successful outcome after thymectomy.

INTRODUCTION: Thymic abnormalities occur as hyperplasia and thymoma. Myasthenia gravis is commonly present in thymoma. Thymectomy possesses risk due to anatomical proximity with vital thoracic structures and myasthenia crisis. PRESENTATION OF CASE: Forty five years female with complaints of difficulty swallowing and weakness of upper limb muscles upon investigation showed mass in mediastinum and antibody test for myasthenia gravis positive. Medical management was done for a month followed by thymectomy. There were no intra and postoperative complications. Medical management was stopped one month after surgery and she is symptom free. DISCUSSION: Thymectomy is the standard of care where median sternotomy is the mainstay approach to surgery. Various other surgical approaches and complications revolving around surgery has been discussed. CONCLUSION: Surgical removal of thymoma cured myasthenia gravis in our case. We focused on proper preoperative optimization of myasthenia gravis symptoms before thymectomy.

Cadaveric renal transplantation: our experience at the Institute of Kidney Diseases & Research Centre, Institute of Transplantation Sciences, Ahmedabad.

In a developing country such as India, cadaveric renal transplantation accounts for only less than 1% of total renal transplantations. The reasons for such a low rate of cadaveric transplantation are many, ranging from lack of awareness to socioeconomic reasons. Our institute conducted a statewide public awareness program and initiated an intercity organ harvesting program. This doubled the cadaveric renal transplantations in the last 2 years. We performed 38 cadaveric transplantations among 190 renal transplantations in the last year (August 2005 to July 2006). We retrieved kidneys from 21 donors, of whom 9 were outside our city. From 21 donors we transplanted 38 recipients; out of whom 3 received dual kidneys and one kidney was discarded. The Mean age of the donors was 41.4 +/- 18.2 years with a mean cold ischemia time of 6.9 +/- 3.8 hours. Sixty-eight percent had delayed graft function. At the last follow-up, which was 190 +/- 98 days, patient survival rate was 90%: 4 patients died, including 2 due to bacterial sepsis and 2 due to cytomegalovirus (CMV) disease. The Graft survival rate was 85%, and the death-censored graft survival rate was 90%. Mean serum creatinine value at the last follow-up was 1.2 +/- 0.3 mg%. There were 5 episodes of acute rejection in 31 patients during first 3 months (16% acute rejection rate). The increase in cadaveric transplantations was associated with satisfactory patient and graft survival despite the high incidence of delayed graft function.

Plasma zinc as a predictor of diarrheal and respiratory morbidity in children in an urban slum setting.

The association between low initial plasma zinc concentration and risk of morbidity over the subsequent 3 mo was examined in a cohort of 116 children aged 12-59 mo recovering from acute diarrhea. Children with low initial plasma zinc (< or = 8.4 micromol/L) had more episodes of diarrhea [risk ratio (RR): 1.47; 95% CI: 1.03, 2.49) and severe diarrhea, defined as passage of > or = 5 liquid stools in a 24-h period, (RR: 1.70; 95% CI: 1.06, 2.72) than did children with normal plasma zinc (> 8.4 micromol/L). The mean prevalence rate of diarrhea associated with fever was 4 times higher in the zinc-deficient group (P = 0.01). Overall, the difference in the number of episodes of acute lower respiratory tract infections (ALRIs) between the two groups was not statistically significant (RR: 1.76; 95% CI: 0.88-3.53) but the mean prevalence rate of ALRIs was 3.5 times higher in children with low plasma zinc (P = 0.05). The increased risk of diarrhea and ALRIs episodes in zinc-deficient children was larger in boys than in girls. These results show that children with low plasma zinc concentrations are at risk for increased diarrheal and respiratory morbidity.

Efficacy of zinc supplementation in reducing the incidence and prevalence of acute diarrhea--a community-based, double-blind, controlled trial.

A community-based, double-blind, randomized trial was conducted in a population of low socioeconomic status in urban India to determine whether daily zinc supplementation reduces the incidence and prevalence of acute diarrhea, especially in those with zinc deficiency. Children 6-35 mo of age were randomly assigned to zinc (n = 286) and control (n = 293) groups and received a supplement daily for 6 mo. Zinc gluconate (10 mg elemental Zn) was given, with both zinc and control groups also receiving multivitamins. The primary outcome measures determined by home visits every fifth day and physician examinations were the number of acute diarrheal episodes (incidence) and total diarrheal days (prevalence). Zinc supplementation had no effect in children 6-11 mo old. In children aged > 11 mo there was significantly less diarrhea in the zinc group. In boys > 11 mo old, supplementation resulted in a 26% (95% CI: 13%, 38%) lower diarrheal incidence and a 35% (95% CI: 20%, 50%) lower prevalence. In zinc-supplemented girls > 11 mo of age, the incidence was 17% (95% CI: 2%, 30%) lower and the prevalence was 19% (95% CI: 4%, 47%) lower. Overall, zinc supplementation resulted in a 17% (95% CI: 1%, 30%) lower diarrheal incidence in children with plasma zinc concentrations < 9.18 mumol/L at enrollment and a 33% (95% CI: 6%, 52%) lower incidence in children with concentrations < 50 mumol/L. In conclusion, zinc supplementation had a significant effect on acute diarrheal morbidity in children > 11 mo old and in children with low plasma zinc concentrations.

Role of enteric adenoviruses and rotaviruses in mild and severe acute enteritis.

The role of enteric-type adenoviruses and rotaviruses in mild and severe acute gastroenteritis was investigated among children younger than 5 years of age seeking treatment at an urban hospital (UH) and at a rural health center (RHC) in India. There were 330 children at the UH and 340 at the RHC; 319 and 315 age matched nondiarrheal children served as controls for the respective groups. Rotavirus was detected in 15.2% of 330 cases and 1.9% of 319 controls at the UH (P less than 0.001) and in 16.5% of 340 cases and 2.9% of 315 controls at the RHC (P less than 0.001). RV excretion was 3- to 5-fold more common in severe compared with mild diarrhea at the UH and at the RHC (P less than 0.001). The detection rate for enteric-type adenoviruses was similar in patients and controls, respectively, at the UH (0.9%; 2.5%) and RHC (3.8%; 2.5%). At the RHC adenovirus types other than 40 and 41 were excreted by 8.8% of the patients and by only 1.0% of the controls (P less than 0.001). It is possible that the diarrheagenic role of adenoviruses may not be restricted to types 40 and 41.
