Background/Aims: The present study aimed at investigating the long-term outcomes and prognostic factors of patients with biliary atresia (BA) diagnosed and followed at a single center. Materials and Methods: Patients with BA treated during 1994-2014 at a large-volume pediatric tertiary referral center were reviewed retrospectively with regard to demographic, clinical, laboratory, and diagnostic characteristics for identifying the prognostic factors and long-term clinical outcomes. Results: Overall, 81 patients (49 males, 32 females) were included. Mean age at diagnosis was 73.1±4.7 (median: 64) days. Of the patients included, 78 patients (96%) underwent a portoenterostomy procedure. Mean age at operation was 76.8±4.7 (median: 72) days. The surgical success rate was 64.8%. A younger age (either at diagnosis or surgery) was the only determinant of surgical success. The 2-, 5-, and 10-year overall survival (OS) rates, including all patients with or without liver transplantation, were 75%, 73%, and 71% respectively, whereas the 2-, 5-, and 10-year survival rates with native liver (SNL) were 69%, 61%, and 57%, respectively. Mean follow-up duration was 9.4±7.5 years. Successful surgery, presence of fibrosis and/or cirrhosis on the liver pathology, and prothrombin time [international normalized ratio (INR)] at presentation were independent prognostic factors for both OS and SNL. Conclusion: A younger age at diagnosis is strongly associated with surgical success in BA. Surgical success, the prothrombin time (INR) at presentation, and liver pathology are independent prognostic factors affecting the long-term outcomes in patients with BA. Therefore, timely diagnosis and early referral to experienced surgical centers are crucial for optimal management and favorable long-term results in BA.

Background: Anaphylaxis is a potentially life-threatening condition caused by a variety of triggers. However, anaphylaxis following an abdominal trauma is an exceptionally rare condition and could be the first and only sign of hepatic hydatid cyst, especially when no obvious etiology is present. Here, we present such a rare case and discuss relevant diagnostic and management strategy in light of the literature. Case report: This case report refers to a 17 year-old previously healthy girl admitted in our pediatric emergency department (ED) for syncope after a minor blunt abdominal trauma. She was hypotensive on admission and shortly after she developed urticaria and angioedema. She was diagnosed with anaphylaxis and treated immediately. Possible etiologies including drug or food ingestion, insect bite, and previous allergy/anaphylaxis history were excluded. After stabilization abdominal imaging was performed, which revealed a ruptured large hepatic hydatid cyst in the vicinity of biliary tree. Albendazole treatment was started and surgical resection was performed after clinical stabilization, which confirmed the cyst rupture into the biliary ducts. Patient recovered without complications after surgery and was discharged uneventfully. Conclusion: This case report highlights that hydatid cyst rupture should be included in the differential diagnosis of anaphylaxis without obvious etiology, particularly in regions where hydatid disease is endemic. Ruptured hydatid cyst leading to anaphylaxis requires timely diagnosis, management and emergent intervention.

Objective: The coronavirus disease 2019 pandemic affected the healthcare systems worldwide. In this study, we aimed to examine the impact of the coronavirus disease 2019 pandemic on injury-related visits. Materials and Methods: We conducted a retrospective analysis of 7648 injury-related pediatric emergency department visits between March 11 and June 30, 2018, 2019, and 2020, and com- pared the total number of visits, triage levels, distributions of injury mechanisms, and admission rates during the pandemic in 2020 to the same period in 2018 and 2019. Results: In the first 4 months of the pandemic, there was a 69.5% drop in all pediatric emer- gency department visits compared to the previous 2 years. Despite this decrease, the propor- tion of injury-related pediatric emergency department visits increased from 14% to 20.9% in 2020 (P < .001). There was a 3.8% increase in the frequencies of patients with high triage acuity levels (T1, T2, and T3) and a 3.8% decrease in patients with low triage acuity levels (P < .001). The domestic injury rate increased from 40% to 60% during the pandemic period (P < .001). Hospitalization rates increased from 6% to 11.5% and admission to intensive care units increased from 0.9% to 3.3%. The differences were statistically significant (P < .001). Visits due to burn increased from 2.7% to 5.2% (P < .001), poisoning from 3.4% to 5.5% (P < .001), bicycle accidents from 3.3% to 6.8% (P < .001), while injuries due to motor vehicle accidents decreased from 2.6% to 1.3% (P = .004) and sports injuries decreased from 8% to 2.1% (P < .001). Conclusion: This study revealed that despite the significant decrease in total pediatric emer- gency department visits, percentages of injury-related visits increased during the pandemic.

Chickenpox is caused by varicella zoster virus (VZV/HHV-3), which is one of the eight human herpes viruses. Although chickenpox has a good prognosis, neurologic complications including encephalitis, acute cerebellar ataxia, myelitis and meningitis may seldom be associated with the disease. Peripheral facial palsy (PFP) is an extremely rare complication in patients with chickenpox. Herein, we report a 12-year-old boy with chickenpox and unilateral peripheral facial palsy, who was successfully treated with short-term steroids and physical rehabilitation.
