Percutaneous Trans-Thoracic Procedures in Children With Tumors of Thoracic Wall, Mediastinum and Lung. The Experience of a Single Institution

Background While percutaneous trans-thoracic procedures (PTTP) are commonly performed in adults with tumors of thoracic wall, mediastinum and lung, the experience is limited in children, in whom however less invasive methods should be the choice for the diagnosis or the identification of small pulmonary nodules that need to be removed, sparing lung tissue. The results of the PTTP performed by the interventional radiologists in our Pediatric Surgery Department are analyzed. Methods CT-guided biopsies, utilizing a 64-slice CTscanner, with low-radiation dose, were performed applying the coaxial technique with 16-18G needles with a single tissue path. For localization of lung nodules before surgery, two 20G-hook wires were positioned beyond the nodule. CT images after each manipulation of the needles were obtained. US-guided biopsies were performed either with or without coaxial technique through a needle bracket. Younger patients required sedation. All patients underwent a chest radiogram two hours after the procedure and remained under observation for 24 hours. Results From January 2015 to March 2019, 23 procedures were performed in 22 patients (Age:16M- 19Y): 6 patients underwent CT-guided biopsy (4 lung nodules, 2 mediastinal mass); 3 underwent 4 CT-guided hook-wire localization of pulmonary nodules, just before surgery; 13 underwent US-guided biopsy (posterior mediastinum 2; anterior mediastinum 5, thoracic/intrathoracic mass 5). Adequate core biopsies were obtained in all patients, except three, who underwent thoracoscopy/thoracotomy. The hook-wires were successfully positioned in all cases, as confirmed by histology. After the procedure, two patients presented perilesional hemorrhage and one pneumothorax, but they did not required treatment. Conclusion PTTP were successful in most patients, without significant complications. These techniques should be encouraged to avoid diagnostic aggressive surgical approaches in children with cancer. For all cases a multidisciplinary team is essential to discuss the indications and planning the procedures

Anatomy of the thorax

Typing \u201canatomy\u201d or \u201cinteractive anatomy\u201d into the search-window of any web browser elicits information on hundreds of potentially useful websites. Most are very helpful in learning what is needed to pass an examination or to prepare a surgical intervention accurately. However, accurate anatomical descriptions for any one approaching thoracic pediatric surgery are needed, and which are the basis of this chapter

Fimosi

In questa pubblicazione, indirizzata alla consultazione del pediatra \ue8 raccolta l'esperienza maturata nella gestione dei pazienti con fimosi. La fimosi \ue8 una patologia conosciuta da diverse migliaia di anni che presenta un\u2019elevata incidenza nella popolazione pediatrica. La gestione dei pazienti con fimosi \ue8 oggetto di discussione, per quanto riguarda l\u2019indicazione terapeutica (timing, finalit\ue0 e tipo di trattamento), per le ripercussioni psicologiche nell\u2019eventualit\ue0 di intervento chirurgico, per la definizione della patologia e per i preconcetti culturali esistenti nella nostra societ\ue0 riguardo le implicazioni psicologiche legate alla circoncisione, pratica molto diffusa nel mondo occidentale (la maggior parte della popolazione maschile negli Stati Uniti \ue8 circoncisa) che, diversamente da quanto si pensa non compromette la funzionalit\ue0 sessuale futura

Metachronous Bilateral Ovarian Teratoma: A Germ-line Familial Disorder andReview of Surgical Management Options

Background: Germ cell tumors in females are uncommon, and bilateral metachronous ovarian teratoma is even exceptional, with sporadic cases described in the literature. Case: We report on a girl in whom a metachronous ovarian teratoma occurred 6 years after the first. The simultaneous onset of germ-line anomalies in other members of the family supports the existence of genetic or environmental factors conferring susceptibility to germ cell lesions. Summary and conclusion: The case here illustrated reminds the issue of the appropriate follow-up of these patients and of their families

Congenital pouch colon: Case series and review of evidences for resection

Background: Congenital pouch colon (CPC) is a rare variant of anorectal malformations (ARM) with its highest reported incidence in India. We aimed to describe five patients affected by CPC, in which the tissue from the terminal dilated colon has been successfully used and to discuss our results on the light of an extended revision of the literature. Materials and Methods: The clinical details of five cases treated for CPC in two Italian Centers were retrospectively reviewed assessing the fate of the terminal dilated colon. Results: In all cases, the tissue from dilated colon has been used. The double vascular system of the dilated pouch allowed increasing bladder capacity (case 4), reconstruction of the vagina (case 3, 5), and lengthening of the colon (case 1, 2, 5). In our series, 3/5 have a good bowel control with daily bowel management after ARM correction. In literature, there are not differences in terms of dependence from bowel management in patients with pouch resected and in patients with pouch saved (P = 0.16). Conclusions: We acknowledge that the analysis of the available literature is limited by the absence of studies with high level of evidence and the removal or the preservation of the abnormal colon tissue seems to follow the surgeon preferences

Management of Congenital Urethral Strictures In Infants. Case Series

Infra-vesical obstruction is uncommon in infants and generally due to urethral valves. Congenital urethral strictures (CUS), instead, defined as a concentric narrowing of the urethral lumen, are exceedingly rare in infants
