    Background: Vesico-ureteral reflux (VUR) is a dynamic event in which a retrograde flow of urine is present into the upper tracts. VUR may occur isolated or in association with other congenital abnormalities or as part of syndromic entities. We present a patient with a bilateral primary VUR, syndromic disease caused by a large deletion of 18q (18q21.3-qter) and terminal duplication of 1p (1p36.32-p36.33). Case report: The patient was 8 years old female with a disease including moderate growth retardation, psychomotor retardation, facial dysmorphism, single umbilical artery, umbilical hernia, urachal remnant, bilateral congenital clubfeet and renal-urinary disease. Chromosomal analysis and Array-CGH revealed two heterozygous chromosomal rearrangements: 1p terminal duplication and de novo 18q terminal deletion. She referred to our clinic to evaluation of bilateral hydronephrosis and right renal cortex thinning. Voiding cystourethrography demonstrated bilateral grade IV VUR and dimercaptosuccinic acid renal scintigraphy confirmed right renal cortex thinning and showed a cortical uptake of 75% of the left kidney and 25% of the right kidney. The patient underwent ureterovesical reimplantation after failure of 3 endoscopic submeatal Deflux injections with VUR resolution. Conclusions: This is the first report involving a patient with 18q-syndrome and contemporary presence of 1p chromosomal terminal duplication. The coexistence of two chromosomal rearrangements complicates the clinical picture and creates a chimeric disorder (marked by characteristics of both chromosomal anomalies). Kidney problems, primarily VUR is reported in 15% of patients affected by 18-q syndrome and no cases is reported in the literature regarding a correlation between VUR and 1p36 chromosomal duplication

    Anorectal Malformations: the Brooke Ileostomy Technique Moves to the Colon

    Colostomy is considered by most authors the first step of treatment for neonates affected by high or intermediate anorectal malformations (ARMs). However, for this subset of patients, the debate between total diverting colostomy (TDC) and loop colostomy (LC) is still ongoing among the paediatric surgeons community. The aim of this paper is to present our experience consisting in applying the Brooke technique, until now used only for ileostomy, in order to perform a functionally diverting loop colostomy (FDLC) in patients with high or intermediate ARMs. At our institution, from January 2014 to December 2018, 12 patients (6 males and 6 females) with high or intermediate ARMs underwent colostomy according to the Brooke ileostomy technique. The only complication observed was mild proximal stoma prolapse in 1 patient. Creation and closure of the stomas were easy, and the final cosmetic result was very satisfying in all patients. We believe that this is a promising technique since it might overcome the drawbacks of a TDC as it is less invasive, easier, and quicker to perform. Furthermore, it guarantees final better cosmetic results, albeit functioning as a TDC

    Iron affects the sphere-forming ability of ovarian cancer cells in non-adherent culture conditions

    Introduction: Detachment from the extracellular matrix (ECM) is the first step of the metastatic cascade. It is a regulated process involving interaction between tumor cells and tumor microenvironment (TME). Iron is a key micronutrient within the TME. Here, we explored the role of iron in the ability of ovarian cancer cells to successfully detach from the ECM.Methods: HEY and PEO1 ovarian cancer cells were grown in 3D conditions. To mimic an iron rich TME, culture media were supplemented with 100 μM Fe3+. Cell mortality was evaluated by cytofluorimetric assay. The invasive potential of tumor spheroids was performed in Matrigel and documented with images and time-lapses. Iron metabolism was assessed by analyzing the expression of CD71 and FtH1, and by quantifying the intracellular labile iron pool (LIP) through Calcein-AM cytofluorimetric assay. Ferroptosis was assessed by quantifying mitochondrial reactive oxygen species (ROS) and lipid peroxidation through MitoSOX and BODIPY-C11 cytofluorimetric assays, respectively. Ferroptosis markers GPX4 and VDAC2 were measured by Western blot. FtH1 knockdown was performed by using siRNA.Results: To generate spheroids, HEY and PEO1 cells prevent LIP accumulation by upregulating FtH1. 3D HEY moderately increases FtH1, and LIP is only slightly reduced. 3D PEO1upregulate FtH1 and LIP results significantly diminished. HEY tumor spheroids prevent iron import downregulating CD71, while PEO1 cells strongly enhance it. Intracellular ROS drop down during the 2D to 3D transition in both cell lines, but more significantly in PEO1 cells. Upon iron supplementation, PEO1 cells continue to enhance CD71 and FtH1 without accumulating the LIP and ROS and do not undergo ferroptosis. HEY, instead, accumulate LIP, undergo ferroptosis and attenuate their sphere-forming ability and invasiveness. FtH1 knockdown significantly reduces the generation of PEO1 tumor spheroids, although without sensitizing them to ferroptosis.Discussion: Iron metabolism reprogramming is a key event in the tumor spheroid generation of ovarian cancer cells. An iron-rich environment impairs the sphere-forming ability and causes cell death only in ferroptosis sensitive cells. A better understanding of ferroptosis sensitivity could be useful to develop effective treatments to kill ECM-detached ovarian cancer cells

    Surgical retroperitoneoscopic and transperitoneoscopic access in varicocelectomy: Duplex scan results in pediatric population

    Objective: This is a retrospective study to compare duplex scan results of laparoscopic Palomo’s technique through retroperitoneal and transperitoneal approach for varicocelectomy in children. We statistically analyzed recurrence, testicular volume growth and complications. Patients and methods: Surgical intervention was performed utilizing transperitoneoscopic (group A) or retroperitoneoscopic access (group B). Duplex scan control was performed after 12 months (T1), after 2 years (T2) and the last one at 18 years old in most patients. Statistical analysis was performed using the t-test for parametric data. Differences in proportions were evaluated using c2 or Fisher’s exact test. Results: We treated 120 children (age range 10e17 years) who presented an asymptomatic IV grade of reflux, Coolsaet 1, associated with a left testicular hypotrophy in 36.6% of the cases (44 patients). No post-operative complications were verified. Duplex scan exam showed an increase of left testicular growth in both groups, with complete hypotrophy disappear in patients in both groups after 24 months. Hydrocele, diagnosed clinically and confirmed with duplex scan, was the most frequent post-operative complication (22/120 cases; 18.3%)

    Circumcision is one of the most common surgical procedures in the world. Despite it is known its wide prevalence for religious and medical reasons in children, it remains a controversial practice in paediatric age. To date, there is no described the gold standard technique to circumcise paediatric patients. We started to use glue for circumcision about 2 years ago. We designed this prospective study with the aim to compare two surgical techniques, which were used in our hospital to perform circumcision in children. The implication for practice was the understanding if there were differences between these approaches related to patient's and parents benefits to manage this condition and benefits for surgeon and hospital in term of saving money and time

    7More than 50% of infants with esophageal atresia have associated anomalies. We present a case report of a 46XX neonate with long-gap esophageal atresia and tracheoesophageal fistula (EA/TEF), anorectal malformation, bowel duplication and vaginal agenesis. This is an unusual association of abnormalities which had not yet described in literature.noneopenAngotti, R; Molinaro, F; Bulotta, A L; Ferrara, F; Sica, M; Bindi, E; Messina, MAngotti, R; Molinaro, Francesco; Bulotta, A.

    No full text
    Neonatal testicular tumors are rare and should be considered in the differential diagnosis of newborn scrotal masses. Juvenile granulosa cell tumor (JGCT) accounts for about 5% of all prepubertal testis tumors. As a benign neoplasm, radical orchiectomy is sufficient for treatment. We report a case of a newborn with a prenatal diagnosis of scrotal mass. After surgery, the histological diagnosis was juvenile granulosa cell tumor. To date the patient is healthy
