The Bethesda System for Reporting Thyroid Cytopathology: Risk of Malignancy in Pediatric Thyroid Nodules.

Introduction: Thyroid nodules are infrequent findings in children, though malignancy rates are higher in this population. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) standardizes the reporting of thyroid fine needle aspiration (FNA) specimens and has become a global reference for assessing the risk of malignancy (ROM) of thyroid nodules. The 2023 update includes pediatric-specific risk predictions and management recommendations.

Impact of the COVID-19 pandemic on surgical skills training in pediatric surgery residents.

Purpose: To analyze the initial impact of the SARS-CoV-2 pandemic on surgical skills training and performance of Pediatric Surgery Residents.

Methods: Retrospective study considering the modifications on the Pediatric Surgery Residency training from March 1st-May 31st, 2020. Exposure to OR learning opportunities was compared to the same 2018-2019 trimesters.

Childhood liver tumors in Argentina: Incidence trend and survival by treatment center. A report from the national pediatric cancer registry, ROHA network 2000-2015.

Background: Information on the epidemiology of pediatric liver tumors in Latin America is limited.

Purpose: To describe the incidence of liver tumors in a pediatric registry in Argentina according to geographic region, national trends over 16 years, and survival related to stage, age, sex, and care center.

Methods: Newly diagnosed liver tumors cases are registered in the Argentine Pediatric Oncology Hospital Registry (ROHA) with an estimated coverage of 91% of national cases.

[Facial nerve schwannoma as differential diagnosis of parotid tumors in pediatrics].

Schwannomas are benign tumors which arise from Schwann cells and take place along peripheral nerves. Extra-temporal facial nerve schwannomas are infrequent and present as painless masses in the parotid region, slow-growing and involvement of the facial nerve. Although rare, they should be taken into account as a differential diagnosis in parotid masses in children.

[Minimally invasive treatment of biliary tract injury secondary to closed abdominal trauma: Clinical case].

Hepatic and biliary tract injuries due to traumatic causes are rare in pediatric patients. Of the total number of patients with closed abdominal trauma, less than 9 % have liver injury, and the frequency varies between 2 and 3 % of biliary tract lesions. Currently, the recommended treatment for closed abdominal trauma with liver injury without hemodynamic repercussion is conservative.

[Fetal ascites as clinical presentation of inferior vena cava agenesis].

Inferior Vena Cava (IVC) is composed of three segments from different embryological origin. Its lack of fusion originates a wide spectrum of anomalies of the IVC. These malformations are present in 0.

[Post traumatic diaphragmatic rupture in children: Case report].

Diaphragmatic rupture is a relatively uncommon entity in pediatrics that can occur as a result of a high-impact trauma. Only between 25 and 50% of the cases are detected in the initial evaluation of the patient, which increases the risk of complications. This paper presents the case of an asymptomatic 8-year-old patient who was referred to our institution after a vehicular accident.

[Intestinal venous vascular malformation: Unusual etiology of gastrointestinal bleeding in pediatrics. Case report].

Intestinal vascular malformations, especially those in the right colon, are a frequent cause of lower gastrointestinal bleeding in adults, but they are a very rare condition in children. Symptoms include acute hemorrhage, intestinal obstruction, or chronic anemia of uncertain etiology, which is the most frequent form of presentation but the most difficult to diagnose and thus properly treat. We report the case of an 11 year old boy admitted to the Emergency Room with abdominal pain, vomits, hemodynamic decompensation, who required expansion and blood transfusion.

[Cervical Castleman's disease. Pediatric case report].

Castleman's disease (CD) is a rare entity, characterized by lymph node follicles hyperplasia. It rarely occurs in children. We present a case of a 9 year old girl with CD in the parotid region.

Choledochal cyst in pediatric patients: a 10-year single institution experience.

Background: Choledochal cysts (CCs) are rare congenital dilatations of the biliar tree. The incidence is 1:150,000. A correct diagnosis and surgical treatment are important because of the long term risks of infection and neoplasia.
