Abdominal pain in children: a case of acalculous cholecystitis.

Acalculous cholecystitis is a rare disease in children. Most cases are associated with systemic infections or with autoimmune pathologies, but it may also occur without predisposing factors. A case observed in an otherwise healthy child is reported.

[Conservative treatment of post-traumatic hepatic hematoma. Case reports]. / Trattamento conservativo dell'ematoma epatico post-traumatico. Casistica clinica.

Post-traumatic hepatic haematomas may need surgical or conservative treatment. TC allows exact stadiation of hepatic lesions, detecting those mandatory for surgical approach. Haemodinamic unsteadiness and/or necessity of > 40 ml/kg blood transfusion suggest serious uncontrollable bleeding, that is surgical emergency. Three cases of post-traumatic heapatic haematomas recovered after conservative treatment (clinical, haematological and radiological survey) are described.

[Recto-cutaneous penile fistula. A description of a clinical case and review of the literature]. / Fistola retto-cutanea peniena. Descrizione di un caso clinico e revisione della letteratura.

This describes a newborn with an imperforate anus associated to a fistulous track extending along the scrotal raphe and opening at the penis top. This variant appears to be a low anomaly. The surgical treatment of this pathology is discussed.

Renal and hepatic angiomyolipomas in a child without evidence of tuberous sclerosis.

A renal neoplasia, displaying the typical features of angiomyolipoma (an admixture of smooth muscle cells, mature adipocytes and tangles of thick-walled blood vessels) was found in a nine-year-old boy. In addition, cytoplasmic crystalloid structures and HMB 45 positivity were found in smooth muscle cells. Similar findings were also observed in a small nodule of the liver. According to literature data, angiomyolipoma is very rare in children and almost exclusively associated with tuberous sclerosis. Our case suggest that the diagnostic hypothesis of angiomyolipoma can not be disregarded when a renal mass is identified in a young patient even in a clinical setting other than tuberous sclerosis.

[Amniotic band syndrome. Clinico-therapeutic considerations on 3 cases]. / Sindrome da briglie amniotiche. Considerazioni clinico-terapeutiche su tre casi.

In three patients with "Congenital Annular Constricting Bands Syndrome" the monstrous leg and foot lymphedemas were aesthetically and functionally cured using the two-stage Ombredanne's crown-like operation. Plaster splints were useful in curing and consolidating the tibia and fibula pseudoarthrosis present in one case and in curing the clubfeet present in the other two cases. Some consideration is made to the different etiopathogenetic theories, proposed in the past and recently, to explain this syndrome.
