Unusual repair in a rare case of hepatothorax due to right-sided diaphragmatic rupture: case report.

Intra-thoracic herniation of abdominal organs following diaphragmatic rupture represents an unusual clinical occurrence with great diagnostic difficulty. The authors present a case of right diaphragmatic rupture related to peritonitis due to perforated duodenal ulcer in previous (1 year before) thoraco-abdominal trauma with complete intra-thoracic herniation of the liver, gallbladder, ascending and transverse colon and lung collapse. The preoperative diagnosis has been based on clinical, chest X-ray, and ultrasound examination.

Valproic acid-induced acute pancreatitis in pediatric age: case series and review of literature.

Valproic acid (VPA) is commonly prescribed medication for epilepsy, migraine and bipolar disorder. Although the common adverse effect associated with VPA are typically benign, less common adverse effect can occur; these include hepatotixicity, teratogenicity and acute pancreatitis (AP). VPA-induced pancreatitis does not depend on valproic acid serum level and may occur anytime after onset of therapy.

[Apudomas: nosographic and physiopathological aspects].

The authors intend to contribute to the knowledge of this complex and in part not fully defined subject of apudomas, in particular with regard to classification criteria and physiopathological aspects. After having examined the characteristics of these neoplasias (probably common embryonal origin, similar radioimmunological, immunohistochemical and ultrastructural characteristics, the capacity to convert amine precursors into amines), the authors focus on the most significant aspect of these carcinoids which, in the light of current knowledge, possess varying but undisputed degrees of biological aggressiveness. They also highlight the importance of the gastroenteric tract as an organ with an endocrine function and lastly affirm the value of the classification which, using the pancreas as the reference organ, distinguishes endocrine neoplasias in this tract into entopic and ectotopic examples.

[Phyllodes breast tumors: apropos 2 cases].

The observation of two cases of phyllode tumors of the breast, one benign and the other malignant, brought the Authors to focus the fundamental aspects of these neoplasias. The histologic coexistence of both epithelial and connectival components, a relative unpredictable clinical evolution, the high frequency of recurrences, the stromal hyperproduction and modifications as expression of malignancy, and the need for large excisions are the fundamental characteristics of these tumors, which are considered transitional forms between benignity and malignancy.
