Chylothorax complicating Gorham's disease.

Gorham's disease is a rare disorder characterized by a proliferation of thin-walled lymphatic vessels (lymphangiectasia) resulting in an osteolysis. A chylothorax is present in about one-fifth of the patients and carries a poor prognosis. In this circumstance, surgery including thoracic duct ligation, pleurodesis, and excision of involved tissue is probably the treatment of choice. It is facilitated by a precise radiological assessment using a computed tomographic scanning coupled with a lymphography. We report such a case.

[Lung volume reduction in patients with emphysema after prolonged ventilatory assistance].

A 42-year-old patient with emphysema was hospitalized in the intensive care unit for an episode of acute respiratory failure. The patient became dependent on invasive mechanical ventilation and surgical lung volume reduction was performed. The indication of lung volume reduction in this pathological situation but was followed by rapid weaning 48 hours postoperatively. The patient was discharged without ventilatory assistance and has not required further ventilatory assistance after more than 2 years follow-up.

[Pleural granulocytic sarcoma. Apropos of a case and review of the literature].

The granulocytic sarcoma is a rare and extramedullary tumor, which is composed of granulocytic precursor cells. The diagnosis remains difficult. Infectious disease are often associated with leukemic processes. Combination of clinical, radiological and pathological findings are useful for diagnosis. On gross examination, the tumor appears green. The detection of myeloperoxidases and the presence of immature eosinophils can help histological analysis. Granulocytic sarcoma occurs before or during an acute leukemia. It is treated like an acute leukemia. Prognostic is greatly improved by early diagnosis and treatment. The lack of cytogenetic abnormalities is associated with a prolonged survival. We describe a new case of rapidly growing pleural granulocytic sarcoma. The uncommon modifications of chromosome 5 long arm in this case could explain the immature eosinophil reaction in that tumor.

[Retroperitoneal leiomyosarcoma originating from the inferior vena cava. A case report].

After a brief review of the literature, the authors report a rare case primitive retroperitoneal leiomyosarcoma originating from the inferior vena cava. The tumor was diagnosed very early thanks to its early symptoms and signs (abdominal pain and palpability), which appeared when the tumor size was only 5 cm. Therefore it was possible a macroscopically radical surgical exeresis even if the anatomical situation was particularly delicate. The low grading and staging of the tumor allowed to express a positive prognosis in spite of the malignant nature of this sarcoma.

[Double-blind evaluation of the effectiveness of cimetidine in the arrest of hemorrhages due to gastroduodenal peptic lesions].

40 patients with an endoscopic diagnosis of bleeding gastric or duodenal lesions have been examined in a double blind study. The haemorrhages were subdivided into slight and serious on the basis of objective parameters. Cimetidine (1.2 g/die i.v.) or placebo in a preparation indistinguishable from the drug were administered to patients. Arrest of the haemorrhage was evaluated on the basis of clinical and endoscopic criteria, and the study was pursued up to 96 hours from the start of bleeding. The effect of cimetidine proved greater than that of the placebo in serious haemorrhage, particularly where due to gastric lesions, but no differences were seen between drug and placebo in the slight haemorrhages.

[Esophagogastroplasty in upper esophageal lesions. Apropos of 4 cases].

Oesophagogastroplasty has been performed in 4 patients in the Turin Department of Emergency Surgery. Three of them presented high neoplastic lesion of the oesophagus, while the fourth was suffering from mediastinic compression due to sclerosing mediastinitis. The technique and results are reported in detail. Indications for surgery for both malignant and benign lesions are presented. The real advantages of the operation with respect to stomach to chest transposition and oesophagocolonplasty which have in the personal series created considerable inconvenience, are discussed. The reasons making it necessary to carry out the operation in two stages, with different modalities, are also discussed. Complications are indicated and postoperative treatment discussed. This plays a notable part in the success of the operation, as does correct technique.
