Spontaneous superior mesenteric vein thrombosis (SMVT) in primary protein S deficiency. A case report and review of the literature.

Superior mesenteric vein thrombosis (SMVT) is an uncommon but important clinical entity that can induce ischemia or infarction of the small and large bowel. It is rare and accounts for 5-15% of mesenteric vascular occlusions. Bowel infarction due to SMVT can present as an acute abdominal disease, requiring urgent laparotomy with resection of the intestinal segment affected. However, the clinical diagnosis of this event remains difficult and invariably requires specific imaging investigations in order to be able to treat the condition as soon as possible. SMVT without bowel infarction can present as persistent, non-specific abdominal pain and nausea with minimal clinical signs, affecting young individuals without any known predisposing disorder, where laparotomy is not an urgent indication. We report a case of a young adult man with SMVT due to a hypercoagulable state (protein S deficiency), in whom an early diagnosis and appropriate anticoagulant treatment prevented any further extension of the thrombotic process and limited the hemorrhagic infarction of the ileum, which simply required a segmental resection.

[Adrenal hemorrhage in neonates: three cases with different clinical and echographic findings]. / Emorragia surrenalica nel neonato: presentazione di tre casi con diverso quadro clinico ed ecografico.

Three cases of neonatal adrenal hemorrhage are described. They presented different clinical findings. Ultrasonography was the investigation of choice. It showed different initial patterns: anechoic in one case, hyperechoic in the others. The literature is reviewed. Usefulness of echography in the diagnosis of adrenal hemorrhage is stressed.

Focal xanthogranulomatous pyelonephritis: diagnostic and therapeutic aspects.

The authors report 2 cases of localized xanthogranulomatous pyelonephritis (XGP) in which computed tomography (CT) permitted to raise a motivated clinical suspicion of inflammatory disease: the surgical exploration documented absence of neoplasm and allowed a conservative therapy implying only the removal of the mass. A literature review confirms that some CT signs in XGP permit differentiation from carcinoma. If they are present, in unifocal cases of disease, the authors suggest a limited surgical approach and a therapeutic strategy as conservative as possible.
