Complete common mesentery revealed by acute perforated appendicitis: case report and review of the literature.

Intestinal malrotation in children is a rare aberration, due to a halt in the rotation and attachment of the primitive gut, it can be asymptomatic if the rotation terminates at 90 degrees, which manifests itself in unusual forms of appendicitis as in our observation, or dangerous in cases of inadequate common mesentery and worsened by small intestine volvulus. This 12-year-old boy experienced abdominal discomfort in the hypogastrium and left iliac fossa 4 days before admission. The pain had been developing in a feverish setting, and the clinical examination had revealed abdominal sensitivity. A biological inflammatory syndrome was detected throughout the biological workup, the CT scan allowed the diagnosis of acute appendicitis on a complete common mesentery, and the patient underwent a laparotomy appendectomy. Even though children frequently experience acute appendicitis in its conventional form, it is nevertheless highly challenging to identify in its atypical forms when intestinal malrotation is involved. An abdominopelvic CT scan is used to make the diagnosis, and appendectomy, preferably with laparoscopy, is the recommended course of action.

Cardiac hydatid cyst: 2 case reports.

Hydatidosis is a parasitic disease that is still prevalent in regions that rear farm animals, notably along the Mediterranean coast. The liver and lungs are most commonly involved. Cardiac hydatidosis has been reported infrequently even in countries in which hydatid disease is endemic. This entity must be known because when undiagnosed and untreated, the risk of fatal complications increases. We report 2 cases of cardiac echinococcal cysts in young men. The first case is an incidentaloma in a patient admitted for pancreatitis. The second case is about a patient admitted for dyspnea. CT scan and MRI were performed showing intraventrucular cystic mass with a calcified wall which was very suggestive of a hydatid cyst diagnosis. We would like to emphasize the relevance of imaging in this context and shade some light on imaging diagnostic tools.

"Urticaire chronique. Au moins un Français sur cinq aura de l'urticaire au moins une fois dans sa vie, mais il ne développera une urticaire chronique que dans 10 % des cas. Le médecin doit savoir reconnaître les caractéristiques essentielles du diagnostic : papules oedémateuses érythémateuses fugaces durant chacune moins de 24  heures +/- angioedèmes durant moins de 72  heures et survenant pendant plus de 6  semaines (quasi) quotidiennement. Toute différence avec cette définition doit faire consulter un dermatologue pour les diagnostics différentiels. Il faut expliquer au patient que l'urticaire chronique n'est pas allergique, qu'elle peut être spontanée ou ne se déclencher que dans certaines circonstances(friction, froid, etc.), ne nécessite un bilan que dans de rares cas, tout en restant à l'écoute sur l'altération de la qualité de vie ressentie. Un traitement en paliers doit être proposé en s'aidant des recommandations françaises sur l'urticaire chronique disponibles en ligne depuis 2019 : antihistaminiques anti-H1 de 2e  génération exclusivement, si besoin à posologie augmentée, puis, en cas d'échec bien défini, adresser à un spécialiste pour un traitement de palier  3 par biothérapie ou immunosuppresseur."

Gastrointestinal hemorrhage caused by small intestinal benign tumors: 2 cases report.

Gastrointestinal bleedings caused by small intestinal tumors are rare and difficult to diagnose because they are not easy to access to the conventional endoscopy. We report two cases, one of them from proximal jejunum and the other one from ileal intestine complicated by intussusception. The two cases were admitted in the emergency department for hematochezia and melena, the diagnosis was established by enhanced helical computed tomography angiography.
