Penile hair coil strangulation of the child

AbstractWe report the case of a child with a delayed presentation of penile strangulation with a coil of hair that resulted in a complete transection of the urethra. Hair coil strangulation of the penis is uncommon. It is also known as penile Tourniquet syndrome. It has been reported with circumcised and uncircumcised penises and it can lead to serious complications like the amputation of the penis. Prompt diagnosis and treatment are necessary to prevent complications

Overview of the first Wendelstein 7-X long pulse campaign with fully water-cooled plasma facing components

After a long device enhancement phase, scientific operation resumed in 2022. The main new device components are the water cooling of all plasma facing components and the new water-cooled high heat flux divertor units. Water cooling allowed for the first long-pulse operation campaign. A maximum discharge length of 8 min was achieved with a total heating energy of 1.3 GJ. Safe divertor operation was demonstrated in attached and detached mode. Stable detachment is readily achieved in some magnetic configurations but requires impurity seeding in configurations with small magnetic pitch angle within the edge islands. Progress was made in the characterization of transport mechanisms across edge magnetic islands: Measurement of the potential distribution and flow pattern reveals that the islands are associated with a strong poloidal drift, which leads to rapid convection of energy and particles from the last closed flux surface into the scrape-off layer. Using the upgraded plasma heating systems, advanced heating scenarios were developed, which provide improved energy confinement comparable to the scenario, in which the record triple product for stellarators was achieved in the previous operation campaign. However, a magnetic configuration-dependent critical heating power limit of the electron cyclotron resonance heating was observed. Exceeding the respective power limit leads to a degradation of the confinement

Effect of the relative shift between the electron density and temperature pedestal position on the pedestal stability in JET-ILW and comparison with JET-C

The electron temperature and density pedestals tend to vary in their relative radial positions, as observed in DIII-D (Beurskens et al 2011 Phys. Plasmas 18 056120) and ASDEX Upgrade (Dunne et al 2017 Plasma Phys. Control. Fusion 59 14017). This so-called relative shift has an impact on the pedestal magnetohydrodynamic (MHD) stability and hence on the pedestal height (Osborne et al 2015 Nucl. Fusion 55 063018). The present work studies the effect of the relative shift on pedestal stability of JET ITER-like wall (JET-ILW) baseline low triangularity (\u3b4) unseeded plasmas, and similar JET-C discharges. As shown in this paper, the increase of the pedestal relative shift is correlated with the reduction of the normalized pressure gradient, therefore playing a strong role in pedestal stability. Furthermore, JET-ILW tends to have a larger relative shift compared to JET carbon wall (JET-C), suggesting a possible role of the plasma facing materials in affecting the density profile location. Experimental results are then compared with stability analysis performed in terms of the peeling-ballooning model and with pedestal predictive model EUROPED (Saarelma et al 2017 Plasma Phys. Control. Fusion). Stability analysis is consistent with the experimental findings, showing an improvement of the pedestal stability, when the relative shift is reduced. This has been ascribed mainly to the increase of the edge bootstrap current, and to minor effects related to the increase of the pedestal pressure gradient and narrowing of the pedestal pressure width. Pedestal predictive model EUROPED shows a qualitative agreement with experiment, especially for low values of the relative shift

Primary Transanal Management of Rectal Atresia in a Neonate

Rectal atresia (RA) with a normal anus is a rare anomaly. We describe a case of rectal atresia in a newborn male presenting with an abdominal distension and failure of passing meconium. The rectal atresia was primarily operated by transanal route

Trois observations de néphrome mésoblastique avant l’âge de 6 mois

Nous rapportons trois observations de néphrome mésoblastique chez deux nourrissons de 3 et 5 mois et chez un nouveau né de 5 jours. Le néphrome mésoblastique congénital ou tumeur de BOLANDE représente 2 à 3% des tumeurs rénales de l’enfant. elle présente des caractéristiques anatomopathologiques, thérapeutiques et pronostiques distinctes du néphroblastome. Il existe plusieurs controverses dans sa prise en charge

Fibroepithelial polyps of the urethra in infants: A report of three cases

Fibroepithelial polyps of the urethra (FEPU) are rare entity in infancy. They are congenital benign tumors. Most patients present with acute retention, hematuria or intermittent bladder outlet obstruction. The treatment of choice is transurethral endoscopic resection. Histological study confirms the diagnosis and the prognosis is excellent. We retrospectively reviewed the medical records of three male patients with fibroepithelial polyps of the urethra that were diagnosed and treated in the department of pediatric surgery of Monastir. The diagnosis was based on voiding cystourethrogram and cystourethroscopy. The treatment was endoscopic resection and histology confirmed the diagnosis in all cases

Multiple Echinococcosis with an unusual location in the spermatic cord treated successfully by Albendazole: A case report

Hydatid cysts are endemic in certain regions of the world. It can affect any organ. However, the primary site to the spermatic cord is an unusual location. Hydatid disease has been reported 5 times in the spermatic cord. The purpose of this study was to report a new case of a child with hydatid disease in the spermatic cord. This cyst is the first case treated successfully by Albendazole without surgery
