Clinical and histopathological study of renal biopsy in Nepalese children: A single center experience.

BACKGROUND: Glomerular diseases are important causes of morbidity and mortality among children in developing countries. Renal biopsy is the gold standard for determining histological diagnosis, prognosis, and therapy options. This study aimed to investigate the clinical, histopathological, and direct immunofluorescence findings of renal biopsy results in Nepalese children under 18 years old. METHODS: In this retrospective cross-sectional study, the available data from children who had undergone kidney biopsy between 2016 and the end of 2020 were evaluated. Demographic data, indications of biopsy, histopathologic findings, and direct immunofluorescence findings were collected and presented. RESULTS: The mean age of the patients was 12.14 ± 4.07 years. Male/female ratio was 1:1. The majority of biopsy cases were aged between 11-15 years of age. The most common indication for biopsy in children was nephrotic syndrome (68.25%). Lupus nephritis with 28 cases (22.22%) had the highest frequency in overall renal biopsies. Minimal change disease (MCD) with 22 cases (17.46%) followed by Ig A nephropathy with 16 cases (12.69%) were the most frequent primary glomerulonephritis. Lupus nephritis showed full house positivity, and MCD showed full house negativity in all Direct immunofluorescence (DIF) parameters, whereas immunoglobulin A nephropathy showed 100% positivity in Ig A in DIF. CONCLUSIONS: Nephrotic syndrome was the most common indication for renal biopsy. The most common primary glomerulonephritis was MCD, while secondary glomerulonephritis was lupus nephritis. Clinical data, light microscopy, and direct DIF played an integral role in the overall final diagnosis.

Pericardial cyst in a one-year-old boy with ventricular septal defect and patent ductus arteriosus.

BACKGROUND: Pericardial cysts are rare, with the most common etiology being congenital. Ventricular septal defect is the most common congenital heart disease in children. However, the combination of pericardial cyst, ventricular septal defect, and patent ductus arteriosus is extremely rare. CASE PRESENTATION: A one-year-old boy with ventricular septal defect and patent ductus arteriosus was planned for surgical correction. Intraoperatively, we made an additional diagnosis of a large pericardial cyst; and the cyst was excised along with ventricular septal defect closure and patent ductus arteriosus ligation. CONCLUSIONS: Pericardial cysts can sometimes be missed with transthoracic echocardiography. Excision of the cyst can safely be done during concomitant cardiac surgery.

A Critically Ill Child with Gangrenous Appendicitis Masquerading as Hollow Viscous Perforation.

BACKGROUND: Severe complications of acute appendicitis (AA) hitherto well described are less common in clinical practice nowadays. When a septic child is encountered with a short history of abdominal symptoms and disproportionate signs of peritonitis further complicated by radiological findings causing a diagnostic conundrum, management becomes exceedingly demanding. Case Presentation. A 10-year-old previously healthy boy presented to the emergency room with generalized abdominal pain associated with fever and jaundice for a day. Blood workup revealed leucopenia, hyperbilirubinemia, hyponatremia, and elevated CRP. Initial radiological evaluation suggested hollow viscous perforation. He was diagnosed to have hollow viscous perforation peritonitis in severe sepsis. At laparotomy, generalized peritoneal contamination was found, the source of which could be traced down to the gangrenous perforated appendix. CONCLUSION: Complicated appendicitis, in children, can present with baffling findings. Timely identification of an ill child, adequate workup, prompt resuscitation, and source control are imperative for a successful outcome.

Multidrug resistant Enterobacteriaceae and extended spectrum ß-lactamase producing Escherichia coli: a cross-sectional study in National Kidney Center, Nepal.

BACKGROUND: Emergence of antibacterial resistance and production of Extended spectrum ß-lactamases (ESBLs) are responsible for the frequently observed empirical therapy failures. Most countries have experienced rapid dissemination of ESBLs producing Enterobacteriaceae isolates, particularly E. coli and Klebsiella pneumoniae. ESBLs are clinically significant and when detected, indicate the need for the use of appropriate antibacterial agents. But antibacterial choice is often complicated by multi-resistance. METHODS: This study was carried from June to November 2014 to study the multidrug resistant (MDR) Enterobacteriaceae and ESBL producing E. coli among urine isolates in hospital setting. Isolates from urine samples were primarily screened for possible ESBL production followed by phenotypic confirmation. Antibiotic susceptibility testing (AST) was done by Kirby Bauer disk diffusion method following Clinical and Laboratory Standard Institute (CLSI) guidelines. RESULTS: Out of 450 urine samples processed, 141 significant growths were obtained including 95 Enterobacteriaceae isolates with 67 E. coli. Among Enterobacteriaceae, 92 (96.84 %) were recorded as MDR and 18 (26.87 %) E. coli were confirmed as ESBLs producers. CONCLUSIONS: Using the phenotypic confirmatory test forwarded by the CLSI, relatively significant E. coli isolates tested were ESBL producers. Also high numbers of MDR organisms were isolated among Enterobacteriaceae. Isolates showed significant resistance to the commonly prescribed drugs. These findings suggest for further study in this field including the consequences of colonization with MDR and ESBL-producing bacteria both in the community and in the hospital setting.
