RESUMO
Background Chronic Spontaneous Urticaria is considered to be an autoimmune phenomenon in half of the total cases. Autologous serum skin test is a simple screening test for the presence of auto-antibodies in chronic urticaria. Significant impairment in quality of life have been observed in autologous serum skin test positive cases. There are limited literatures on chronic spontaneous urticaria, autologous serum skin test and associated Dermatology Life Quality Index in Nepal till date. Objective To find the proportion of autologous serum skin test positive cases in chronic urticaria and impairment in quality of life in such patients. Method This was a retrospective review of outpatient records of patients diagnosed with chronic spontaneous urticaria, from January 2018 to December 2019, from a tertiary care hospital in Kathmandu, Nepal. Details of the patients, autologous serum skin test and dermatology life quality index scores were analyzed and presented. Result Among the total 114 cases positive autologous serum skin test was seen in 48.2% of cases. The mean total Dermatology Life Quality Index score was 8.06±6.64. A significantly higher quality of life impairment was observed in in patients with positive autologous serum skin test as compared to the negative ones. The odds of finding a positive autologous serum skin test in patients with angioedema was 2.1, however the difference was not statistically significant. Conclusion Chronic spontaneous urticaria was more common in females as compared to males. A positive autologous serum skin test was present in half of the patients which was in turn associated with a greater impairment of quality of life.

Background Tricuspid regurgitation is frequently present in patients with mitral valve disease and most of this tricuspid regurgitation present are significant. Objective To find out the prevalence of tricuspid regurgitation in adult patients present in our hospital who are planned for isolated mitral valve surgery for mitral stenosis, mitral regurgitation or both. Patients with moderate and severe tricuspid regurgitation were considered as significant. Method This was the retrospective cross-sectional study performed at Shahid Gangalal National Heart Center of Nepal. All cardiac surgical patients scheduled for isolated mitral valve surgery during the 3 years' period from 2017 to 2020 were enrolled in the study and presence or absence of significant tricuspid regurgitation were recorded and analysed. Result Out of total patients 65% (663) of the cases with mitral valve pathology had significant tricuspid regurgitation. Out of the total mitral stenosis cases 70% were associated with significant tricuspid regurgitation, 62.6% of the cases of mitral regurgitation had significant tricuspid regurgitation and 64.8% of patients with combined mitral stenosis and regurgitation were associated with significant tricuspid regurgitation. Conclusion Significant tricuspid regurgitation is present in most of the cases with isolated mitral valve pathology. So routine tricuspid valve evaluation and repair if needed during mitral valve surgeries is recommended.

A 34 years old female presented with complains of photophobia since 6-7 months. On examination, she had anisocoria of 4 mm in room light which increased in bright light. The left pupil was dilated and unresponsive to direct and indirect light stimuli. It did however, constrict slowly on near fixation followed by slow redilatation on distance fixation. A diagnosis of Adie's tonic pupil was made since left pupil constricted with instillation of dilute pilocarpine 0.1%. Her symptoms of photophobia and blurred vision immediately resolved. Photochromatic glasses and dilute pilocarpine 0.1% three times a day were prescribed. Prompt symptomatic relief of photophobia and blurred vision was observed.

Background Myocardial revascularization surgery has shown better long term survival expectancy compared to medical therapy in patient with impaired left ventricular function. Objective To evaluate the change in ejection fraction after 90 days in patients who underwent coronary artery bypass surgery and had preoperative left ventricular ejection fraction of less than and equal to 45% in a single cardiac center of Nepal over the period of 2 years. Method Out of 82 eligible patients during 2 years, 3 patients expired in immediate postoperatively and 24 patients had loss of 90 days' follow up. So, they were excluded from the study. Total 55 patients were taken for the study for whom statistical analysis was done to compare preoperative ejection fraction with post-operative 90 days' ejection fraction. Result Single vessel disease was present in 2(3.6%) patients, double vessel disease in 7(12.7%) patients and triple vessel disease in 46(83.6%) of the patients. In 2(3.6%) patients 2 grafts, in 18(32.7%) patients 3 grafts, in 33(60%) patients 4 grafts and in 2(3.6%) patients 5 grafts were placed for revascularization. The mean left ventricular EF in preoperative patients was 37.12±5.69% which improved to 45.80±10.00% in postoperative follow up at 90 days which was statistically significant (p=0.000). Conclusion Surgical revascularization of myocardium in preoperatively impaired left ventricular function patients helps improve left ventricular ejection fraction postoperatively. So we suggest surgical revascularization in patient with low ejection fraction for improvement of myocardial function. Hence improve survival rate in these patients.

Background Health financing is a major domain of health system building blocks. With the epidemiological transition and increasing trend of Cardiovascular diseases (CVDs), it is crucial to assess the status of health financing to address the gap of prevention, control, and treatment of CVDs in Nepal. Objective This paper aims to assess the situation of healthcare financing on Cardiovascular diseases in Nepal. We framed three key functions of health system financing: (a) revenue collection, (b) pooling of resources, and (c) purchasing of services for this study. Method We used sequential explanatory mixed-method research design. We conducted desk reviews, analyzed secondary data on health financing followed by Key-Informant Interviews with five relevant policymakers and experts between February and September 2019. We obtained the Ethical clearance from the Nepal Health Research Council. Result Out of pocket (OOP) expenditure remains the highest source (52%) of total health care expenditure in Nepal, and two third of it is made for NCDs. Out of total current health expenditure on outpatient and inpatient services for fiscal year 2015/16, only 7% of total NCDs was spent on CVDs. Hypertension is the third-most utilized insurance service out of 36 CVD related services provided by the Health Insurance Board. The existing health related social service schemes covers the high costs associated with treatment, and streamlining these services including provider payment mechanisms with the health insurance program could open up opportunities to expand quality CVD services and make it accessible to the marginalized population. Conclusion Health Financing is the integral part of the health system. With the rising burden of cardiovascular diseases and its impact on impoverishment due to high OOP, integrated health care services, budget specification based on the evidence-based burden of disease such as CVD needs to be prioritized by the government.

Background Acute renal colic is the most frequent clinical presentations of renal stone and a common cause of patient visits to emergency departments worldwide. The prevalence of the renal stone disease has increased steadily over the past decades. Objective To describe the prevalence, epidemiological features and clinical management of renal colic patients at emergency department in Kathmandu University Hospital, Kavre, Nepal. Method Two hundred and thirty-six patients with acute renal colic presented in emergency department during a six-months period were included in the study. Using a standard predesigned proforma, demographic characteristics, presenting symptoms, practice of pain management and outcome were investigated. Renal colic attacks in patients were defined according to International Classification of Diseases, Tenth Revision, and Clinical Modification-10. Result Prevalence of renal colic was 2.61%. Mean age of the patients was 33.9±13.7 years. More than half of participants were male (54%). Majority of the patients (47.9%) were from Kavrepalanchowk district. The most common presenting symptom of the patients was flank pain on affected side (79.2%). In almost 43% of patients, diclofenac sodium was administered as a first line analgesic. There was no significant difference between diclofenac and ketolorac with respect to the need of second line analgesic (Chi-square value: 0.19, p value = 0.664). Conclusion Prevalence of renal colic was 2.61% at Dhulikhel hospital. More male pateints were affected and the most common presenting symptom was flank pain on the affected. Diclofenac and ketorolac are equally effective for the pain management of renal colic patients.

We report two cases of cutaneous leishmaniasis in natives of central region of Nepal. The first patient in our series, an adult female, presented with a small nodule on the philtrum of upper lip and the second case, a male child, presented with two crusted plaques on forehead. The final diagnosis was based on histopathological findings; however, species characterization was not possible because of its unavailability in the country. These patients responded well to the treatment with Miltefosine (First case) and Fluconazole (second case). Moreover, these cases sparks a question about the origin of diseases in this region and calls for further research in future to find out the cause and prevalence of this disease in Nepal. This case report also emphasizes to consider cutaneous leishmaniasis as differential diagnosis for granulomatous presentations in our context.

BACKGROUND: Little is known about xeroderma pigmentosum (XP) in Himalayan countries. OBJECTIVE: To describe clinical characteristics of XP in Nepal and investigate its genetic bases. METHODS: This study was carried out on all consecutive patients referred for XP to a Nepalese tertiary referral centre in 2014-2015. Clinical data were collected using a standardized questionnaire. DNA was extracted from salivary samples, and next-generation sequencing (NGS) was conducted using a panel covering all 8 known XP genes (classical XP (XP-A to XP-G) and XP variant) and a skin cancer modifier gene, the melanocortin 1 receptor gene (MC1R). RESULTS: Seventeen patients (median age: 15 years; range: 1-32) were included. Twelve had skin cancers (including a total of 8 squamous cell carcinomas, 60 basal cell carcinomas, ocular carcinomas requiring an orbital exenteration in 3 patients, but no melanoma). Fifteen patients carried the same homozygous non-sense XPC mutation c.1243C>T, p.R415X. A homozygous non-sense XPA mutation (p.W235X) was found in the only patient with a history of early severe sunburn reaction and associated neurological symptoms. Associated genetic alterations included heterozygous missense variants in XPD/ERCC2 gene and the presence of MC1R variant R163Q in 5 and 9 patients, respectively. CONCLUSION: Although not previously reported, XP seems frequent in Nepal. Patients often presented with a very severe phenotype after a long history of excessive sun exposure without knowledge of the disease. Fifteen of 17 had the same p.R415X XPC mutation, which seems very specific of XP in Nepal, suggesting a founder effect. NGS analyses frequently revealed associated genetic alterations which could play a modifier role in the clinical expression of the disease.

Background Forearm fractures in pediatric population is usually managed conservatively. Unstable fractures need operative intervention like closed or open intramedullary nailing or open reduction and internal fixation with plates and screws. However, there is no consensus regarding the method of treatment according to age group. Objective To standardize the use of elastic nailing system as effective form of treatment in terms of function, cost and lower complications as compared to widely used titanium nails in developed countries.Method Sixty eight pediatric patients with both bone forearm diaphyseal fractures were managed with closed reduction and intramedullary fixation with rush nail or k-wire and followed at least for 6 months for evaluation of radiological and functional outcome. Result Patients were divided into two age groups, Group A for age of 5 to 9 years (26 patients) and Group B for age of 10-15 years (42 patients). The mean time for union for Group A patient was 7.31 weeks which was significantly lower than that of Group B patients of 9.33 weeks (p-value < 0.05). All the patients in Group A had excellent outcome and 36 (85.7%) patients had excellent outcome and 6 (14.3%) had good outcome in Group B. 5 out of 68 cases (7.35 %) had minor complications (2 in Group A and 3 in Group B). The mean time for implant removal was 17.9 weeks in Group A and 22.9 in Group B. Conclusion Intramedullary fixation for unstable diaphyseal both bone fractures of forearm is safe and cost effective method of treatment with good to excellent functional outcome with union time being significantly lower in younger age group.

Delayed graft function (DGF) is a common and costly complication of kidney transplantation. In July 2011, we established a multidisciplinary DGF clinic managed by nurse practitioners to facilitate early discharge and intensive management of DGF in the outpatient setting. We compared length of stay, 30-day readmission, acute rejection, and patient/graft survival in 697 consecutive deceased donor kidney transplantations performed between July 2009 and July 2014. Patients were divided into three groups: no DGF (n = 487), DGF before implementation of the DGF clinic (n = 118), and DGF clinic (n = 92). Baseline characteristics including age, gender, panel reactive antibody, retransplantation rates, HLA mismatches, induction, and maintenance immunosuppression were not significantly different between pre- and post-DGF clinic groups. Length of stay was significantly longer in pre-DGF clinic (10.9 ± 6.2 vs. 6.1 ± 2.1 days, p < 0.001). Thirty-day readmission (21% vs. 16%), graft loss (7% vs. 20%), and patient death (2% vs. 11%) did not differ significantly between pre- and post-DGF clinic. Patients in the DGF clinic were less likely to develop acute rejection (21% vs. 40%, p = 0.006). Outpatient management of DGF in a specialized clinic is associated with substantially shorter hospitalization and lower incidence of acute rejection without significant difference in 30-day readmission or patient and graft survival.

BACKGROUND: Little information is available on the risk factors for graft loss in kidney transplant recipients with BK polyomavirus (BKPyV) nephropathy (BKVN) in the presence or absence of antibody-mediated rejection (AMR). METHODS: We examined the risk factors for graft loss in consecutive kidney allograft recipients with biopsy-confirmed BKVN, with or without concomitant AMR. RESULTS: A total of 1904 kidney transplants were performed at our institution during 2005-2011. Of these, 330 (17.33%) were diagnosed with BKPyV viremia, and 69 were diagnosed with BKVN (3.6%). Eleven patients had a concomitant diagnosis of AMR. Patients with AMR were characterized by significantly higher peak panel-reactive antibody, retransplant rates, and desensitization preconditioning at the time of transplantation, as well as microvascular inflammation (MVI = glomerulitis + peritubular capillaritis), C4d score, and donor-specific antibody at the time of diagnosis (P ≤ 0.01). Treatment with plasma exchange, intravenous immunoglobulin, and cidofovir was more prevalent in this group (P ≤ 0.02). Univariate analyses assessing the risk factors for graft loss in all patients with BKVN, identified an independent association of African-American race, deceased-donor transplantation, serum creatinine (Scr), MVI, and early disease (BKVN within 6 months of transplant) with poor outcomes. Multivariate analyses retained only 3 variables: Scr >2 mg/dL (hazard ratio [HR] = 4.3, 95% confidence interval [CI] 1.9-9.7, P = 0.0004), early BKVN (HR = 2.7, 95% CI 1.3-5.3, P = 0.004), and MVI (HR = 1.8, 95% CI 1.2-2.8, P = 0.008). CONCLUSIONS: These observations suggest that, in patients with BK infection, early BKVN, Scr >2, and MVI are predictors of poor outcomes. Further studies are needed to determine effective treatment strategies for BKVN, with or without AMR.

Round window rupture following barotrauma such as diving and air travel is well documented. However, we describe a case of round window rupture following a slap to the ear, which has not been described previously. A 12-year-old boy was slapped by his teacher in rural Nepal over his left ear and immediately noted hearing loss. There was no dizziness or tinnitus. He presented to our unit 21 days after the trauma and examination showed a perforation of the tympanic membrane in the anterior inferior quadrant with an otherwise normal ear examination and no nystagmus seen. Audiogram showed a left profound hearing loss, which was supported by auditory brainstem response test. Exploratory tympanotomy showed active perilymph leakage from the round window niche as demonstrated in the video attached. The round window was packed with cartilage and fascia to address the perilymph leakage. The patient was discharged the following day without any complications. This is an unusual cause for round window membrane rupture where the patient presented with hearing loss as his only symptom. Tympanotomy is recommended for patients with hearing loss following trauma with normal computed tomography imaging to exclude perilymph leak secondary to inner ear barotrauma.

BACKGROUND: The prognostic value of pretreatment complete blood count (CBC) data, including absolute lymphocyte count (ALC) and the neutrophil-to-lymphocyte ratio (NLR), has been reported for many diseases with decreased ALC and increased absolute neutrophil count (ANC) and NLR values correlating with worse outcomes. There is minimal data relating these hematologic parameters to oropharyngeal squamous cell carcinoma (OPSCC) prognosis. This study evaluates the prognostic value of pretreatment CBC data in OPSCC on overall survival (OS) and progression-free survival (PFS) in relation to HPV status. METHODS: A single-institutional retrospective review of patients with pretreatment hematologic data who received radiation for OPSCC was performed. Univariate and multivariate (UVA/MVA) Cox proportional hazard regression analyses were performed to identify prognostic variables. Translational studies related outcomes to the degree of tumor-infiltrating lymphocytes (TILs) in histologic specimens. RESULTS: From 2007 to 2018, 201 patients were treated for OPSCC. Median follow-up was 40 months. 3-year OS was 86.2% in the HPV-positive cohort, 46.3% for HPV-negative. Median NLR was 3.04. NLR ≥ 3 was associated with worse PFS (HR 1.67, p = 0.044. In the subset of 158 HPV + patients, MVA revealed increasing ALC to be associated with improved OS (HR 0.53; p = 0.040) and PFS (HR = 0.48; p = 0.0075). On UVA, high-TIL infiltration at diagnosis was associated with improved OS. CONCLUSION: In a cohort of HPV + OPSCC patients, increasing ALC is associated with improved OS and PFS. Our study is the first to identify pre-treatment ALC as an independent prognostic factor in HPV-associated OPSCC.

Surfactants are the most common inactive ingredients used in topical drug products. Surfactants in topical products play many functional roles such as emulsifiers, permeation enhancers, and solubilizers. This study was aimed to evaluate the influence of incremental change in the concentration of a surfactant (tween 80) on the quality attributes and performance of semisolid topical products. Four creams were prepared using metronidazole as a model drug using the same manufacturing protocol and similar composition except for the concentration of tween 80, which was increased by 5% w/w across SF1 to SF4. The quality attributes like globule size, pH, drying rate, and in-vitro permeation profile were characterized. The critical quality attributes did not differ significantly across the products. However, there was a significant difference in the permeation profile of the products. The permeation flux (Jmax) varied from SF1 to SF4 (51.25 ± 35.29 to 307.98 ± 138.89 ng/cm2/h, respectively). The reason for the difference in the performance of products despite having consistent quality attributes was investigated. One of the major reasons was found to be the difference in the time course of degree of saturation of drug during the evaporative metamorphosis. This study confirms that the time course of degree of saturation is one of the important quality attributes of the topical product that could influence bioavailability and performance of topical products.

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.
LIEU: Hôpital universitaire de Tribhuvan, Katmandu, Népal. 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
We report a case of recalcitrant nodular vasculitis in a 23 years old male who was treated successfully with methotrexate. He presented to our Dermatology out Patient Department, Tribhuvan university teaching hospital with complaints of recurrent painful discharging ulcer over bilateral calf and lower legs of three years duration. The diagnosis of nodular vasculitis was made on the basis of the clinical presentation and the histopathological findings. The patient was treated with anti-tuberculosis treatment with initial good response; however the lesions persisted later on, despite completing the course of ATT. The patient did not respond to treatment with systemic corticosteroids also. On starting methotrexate, the lesion started healing within a period of two weeks and there was significant improvement in subsequent one month. This case report highlights the efficacy of methotrexate in the treatment of recalcitrant nodular vasculitis.
RESUMO
BACKGROUND: Cancer of the breast is the second most common cause of cancer in women. Mass in the breast, whether benign or malignant is a cause of anxiety to the patients and the family members. All breast lumps are considered to be carcinomas until proved otherwise and are the causes of concern both for the patient and surgeon. METHODS: This is a retrospective study conducted in Kathmandu Model Hospital for a total duration of three years from August 2007 to August 2010. RESULTS: 114 sample of breast tissue sent for histopathology were studied. Peak incidence of benign lesion was in between 21-30 years and malignant lesions in between 31-50 years. No breast lesions were seen in the first decade of life. Cancer of the breast was seen in 12.28% of cases. Fibroadenoma and fibrocystic disease were the commonest benign lesion and infiltrating ductal carcinoma was the commonest malignant lesion. Specimens from 10 male breasts were received. Gynaecomastia was the most common lesion encountered in males. Infiltrating ductal carcinoma was seen in a 70 year old male.

Hepatic epitheliod hemangioendothelioma (HEHE) is a rare tumor of vascular origin with unpredictable malignant potential. We describe our experience with four biopsy-proven HEHE cases that were considered for orthotopic liver transplant (OLT). Three patients had preserved hepatic function and despite extensive disease burden did not develop disease progression while awaiting OLT. We were able to utilize the review process allowed by United Network of Organ Sharing to obtain additional priority for OLT for these patients. This led to expedited organ allocation and excellent post-OLT outcomes.
