Publication Assessment of Bacterial Profile and Antimicrobial Susceptibility Pattern of Bacterial Isolates from Blood Culture in Tertiary Level Paediatric Hospital of Nepal(Nepal Paediatric Society (JNPS), 2023) Shrestha, Anil Kumar; Sharma, Nisha; Bhattrai, Pratiksha; Pokhrel, Nayanum; Bajracharya, Sohani; Sah, Umesh Prasad; Paudel, PrajwalAbstract: Introduction: Bloodstream infection is a major cause of morbidity and mortality which requires antibiotic treatment. Antimicrobial resistance is an emerging serious public health threat in both developed and developing countries. Children are more susceptible to infections requiring an appropriate choice of antibiotic based on blood culture. This study aims to investigate the bacteriological profile and antibiotic sensitivity pattern of blood culture isolates and compare the yield of bacterial growth between Brain Heart Infusion Broth (BHIB) or BD BACTEC culture media. Methods: A total of 12,795 blood samples were sent for bacteriological culture either for BHIB or BACTEC techniques, 10994 and 1801 samples respectively. Chi-square test was used for showing association between BACTEC and BHIB among isolates. Results: The findings showed that the BACTEC method detected more positive isolates than the BHIB method. The rate of isolation was found highest among children under five years. The most common pathogens isolated were Staphylococcus species (28.1%), Staphylococcus aureus (25.6%), Acinetobacter species (12%), Pseudomonas species (8.2%), Klebsiella species (6.6%), CONS (4.4%), Escherichia coli (4.4%), Salmonella Typhi (3.5%), Enterobacter species (3.2%) and Streptococcus species (0.3%). Conclusions: Staphylococcus aureus was the commonest isolate identified in the current study. BACTEC culture method detected the higher percentage of isolates than BHIB method.Publication Congenital Mesoblastic Nephroma: A Case Report(Nepal Medical Association, 2023) Simkhada, Ankita; Paudel, Ramesh; Sharma, NishaAbstract Congenital mesoblastic nephromas are rare renal tumours that are encountered in paediatric age group. A term female neonate at the end of first week of life presented with bilateral lower limb swelling. On radiological evaluation, ultrasonography revealed an intra-abdominal mass which was managed with radical nephroureterectomy. Histopathological examination confirmed a diagnosis of congenital mesoblastic nephroma of mixed subtype.Publication Ewing's Sarcoma of Rib in a Four Year Old: A Case Report(Nepal Medical Association, 2021) Kunwar, Saru; Sharma, Nisha; Giri, Bishnu Rath; BC, Bom; Shrestha, Anil KumarAbstract: Although rare, the Ewing’s sarcoma family of tumors represents the second most common primary bone malignancy that typically occurs in adolescents and young adults aged 10-25 years, presenting with localized pain and swelling of a long bone. We report a case of Ewing’s sarcoma of rib in a four years old child that presented with acute onset of fever, cough, shortness of breath and was initially treated as pneumonia. Although the patient did not belong to typical demography and the symptoms were suggestive of infective pathology, careful scrutiny of the radiographic findings led to further investigations and diagnosis of Ewing’s sarcoma of rib after correlating computerized tomography scan findings with immunohistochemistry reports.Publication Histopathological Spectrum of Renal Tumors in Adults in Nephrectomy Specimens in a Tertiary Care Center(Institute of Medicine, 2022) Sharma, Nisha; Maharjan, DaisyABSTRACT Introduction: Renal neoplasms are heterogeneous tumors with clinical picture, prognosis and therapeutic implications differing with the various histological subtypes. There are limited studies on adult renal tumors conducted in Nepal so far. This study aims to provide a better assessment on the histopathological spectrum of renal neoplasms in adult population. Methods: This is a descriptive study of all the nephrectomy specimens of adults received at Department of Pathology, Tribhuvan University Teaching Hospital from January 2013 to January 2020. Results: There were 75 males and 35 females with mean age being 51.8 years. Malignant tumors (99 cases, 90%) were more common than benign tumors (11 cases, 10%). Renal cell carcinoma (RCC) was the most common malignant tumor consisting of 91 cases (82.72%) followed by 6 cases of urothelial carcinoma (5.45%) and 2 cases of primitive neuroectodermal tumor. (PNET) (1.8%). Clear cell RCC (78 cases, 70.90%) was the commonest histological subtype of RCC followed by papillary RCC (8 cases, 7.2%) and chromophobe RCC (2 cases, 1.8%). 42.65% of the cases of clear cell RCC were of WHO/ISUP grade 2, whereas, most of the cases of papillary RCC were of low grade (Grade 1, 37.5%). Majority of Renal cell carcinomas were in stage pT1a (28 cases, 34.56%). Conclusion: Clear cell RCC was the most common renal tumor in adults comprising the majority of cases. These tumors mostly demonstrated WHO/ISUP Nuclear grade 2 and early stage of presentation (pT1). Papillary RCC was the second commonest RCC and mostly presented at lower nuclear grade (WHO/ISUP Nuclear grade 1). Urothelial carcinomas demonstrated higher nuclear grade and stage compared with RCC. Keywords: Grade, histologic subtypes, renal neoplasms, stagingPublication Low Grade Appendiceal Mucinous Neoplasm: A Report of Three Cases(Institute of Medicine, 2020) Sharma, Nisha; Karna, Alina; Jha, AbhimanyuABSTRACT Low-grade appendiceal mucinous neoplasm (LAMN) is an uncommon malignancy with varied clinical features. The most alarming complication of this neoplasm is seeding of mucin into the adjacent peritoneum leading to pseudomyxoma peritonei (PMP). We report three cases of LAMN. Two cases were seen post appendicectomy in 23-year old and 36-year old females. The third case was seen in 53-year-old male post Whipple procedure and hemicolectomy. LAMNs are often diagnosed incidentally, as clinical presentation is barely specific and resembles acute appendicitis. Hence it is imperative to examine all appendicectomy specimens not to miss cases of appendiceal mucinous neoplasm which can have implications on the further management of the patient. Keywords: Appendectomy, mucinous appendiceal neoplasm, pseudomyxoma peritoneiPublication Meropenem Resistance among Acinetobacter Positive Clinical Samples in a Tertiary Care Centre in Nepal: A Descriptive Cross-sectional Study Authors(Nepal Medical Association, 2021) Sharma, Nisha; Thapa, Bibechan; Acharya, Ashirbad; Raghubanshi, Bijendra RajAbstract: Introduction: Antimicrobial-resistant Acinetobacter species are implicated in a variety of infections including nosocomial bacteraemia, secondary meningitis, and urinary tract infections. Carbapenem including meropenem-resistant Acinetobacter is recognized as one of the most difficult antimicrobial resistant gram-negative bacilli to control and treat. It was classified as an urgent threat by Centers for Disease Control and Prevention in 2019 Antibiotic Resistance Threats Report. This study was carried out to determine the prevalence of meropenem resistance among acinetobacter positive clinical samples in a tertiary care centre. Methods: A descriptive cross-sectional study was carried out in microbiology department of Clinical Laboratory Services among Acinetobacter positive clinical samples of a tertiary care center in Nepal. The culture and sensitivity reports of various clinical samples from April 2018 to April 2020 which were positive for Acinetobacter species were taken from hospital records section. Convenience sampling was done. Meropenem-resistant Acinetobacter samples were studied. Ethical approval was received from Institutional Review Committee (Ref No. 076/77/40). Analysis of data was done using Statistical Package for the Social Sciences version 26. Point estimate at 95% Confidence Interval calculated with ferquency. Results: Out of 121 Acinetobacter isolates, prevalence of meropenem-resistant Acinetobacter was reported in 93 (76.9%) at 95% Confidence Interval (69.39-84.40). Among the meropenem-resistant Acinetobacter samples, most of the samples were collected from the sputum 70 (75.2%) followed by blood 8 (8.6%). Conclusions: High prevalence of meropenem-resistant Acinetobacter species in our hospital setting is alarming. In addition, there is emergence of resistance against even the last resort drugs which is creating a treatment crisis.Publication Prevalence of Self Induced Abortion by Self-Administration of Abortive Pills among Abortion-related Admissions in a Tertiary Care Centre(Nepal Medical Association, 2020) Thapa, Bibechan; Sharma, Nisha; Dwa, Yam PrasadAbstract: Introduction: Each year, unsafe medical abortion costs the lives of thousands worldwide. Despite the legalization of abortion in Nepal in 2002, many still seek services from unauthorized sources. This has led to grave consequences including death. Our objective is to find out the prevalence of self-induced abortion by self-administration of abortive pills and related complications. Methods: It is a descriptive cross-sectional study carried out among abortion-related admissions in a tertiary care center from June 15 2018 to March 15, 2020. Ethical approval was taken from the institutional review committee (076/077/51). Data was collected using pre-designed proforma and analyzed in Statistical Package for the Social Sciences version 26. Point estimate at 95% Confidence Interval (CI) was calculated along with frequency and proportion for binary data. Results: Out of 223 cases enrolled, 37 (16.6%) (9.6-23.6 at 95% Confidence Interval) were self-induced abortion cases by self-administration of abortion pills. The mean gestational age at the time of intake of pills was 7+6±3+1 week of gestation. The majority were diagnosed with incomplete abortion 14 (37.8%) followed by septic abortion 8 (21.6%). A surgical evacuation was performed in 25 (67.6%). Anemia was observed in 19 (51.3%) with severe anemia in 4 (10.8%). Blood transfusion was carried out in 14 (37.8%). Post abortive contraception was accepted by only 16 (42.3%). Conclusions: Medical abortion is safe if done under supervision but self-induced abortion by self-administration of abortion pills has a high complication rate. Therefore, further studies exploring a different dimension of the serious issue is the need of time.Publication Vitamin B12 Deficiency Resembling Acute Leukemia: A Case Report(Nepal Medical Association, 2021) Sharma, Nisha; kunwar, Saru; Shrestha, Anil KumarAbstract: Vitamin B12 deficiency in children can cause megaloblastic anemia, poor growth, and increased chances of infections. It is an important reversible cause of bone marrow suppression which at the time of presentation can mimic hematological malignancy. Therefore, it should be considered as a differential diagnosis in cases suspected of acute leukemia. We report a case of 14 months old child who had atypical presentation of vitamin B12 deficiency. He had chronic fever, decreased feeding and increased paleness for one year. Pancytopenia with severe anemia was present along with 19% reactive/atypical cells in peripheral blood smear suggesting acute leukemia. However, bone marrow aspiration and biopsy showed features of megaloblastic anemia. Vitamin B12 level measured was very low and treatment with cyanocobalamin caused drastic improvement in the child’s condition.
