Epidemiology of non-gastroenteropancreatic (neuro)endocrine tumours.

The widespread availability and reliability of immunohistochemical techniques in the last three decades have allowed researchers to identify cells with common neuroendocrine markers in virtually every organ. As a whole, these neuroendocrine cells form the so-called diffuse neuroendocrine system. Tumours arising from the cells of the diffuse neuroendocrine system are defined as (neuro)endocrine tumours (NETs).

[Pneumothorax in pregnancy. A review of 16 cases including one of the authors'].

Pneumothorax in pregnancy raises several problems especially of therapy. In the present study we report a case observed in our Institution and literature data on 15 further cases. Pneumothorax occurred in 9 cases in the course of pregnancy, in 6 cases during delivery and in 1 case in the post-partum period.

Mediastinoscopy vs. anterior mediastinotomy in the diagnosis of mediastinal lymphoma: a randomized trial.

We selected 95 patients with mediastinal adenopathy and no signs of goiter, myasthenia gravis or mediastinal involvement by other disease. All patients underwent, for screening purposes, transthoracic fine needle aspiration biopsy based on chest x-ray and CT findings. Patients were then subdivided into 4 groups.

Intensive alternating combination chemotherapy and high dose chest radiotherapy in small cell lung cancer.

Sixty-nine patients, 32 with limited and 37 with extensive small cell lung cancer (SCLC), were admitted to the present study. Patients with limited disease underwent alternating combination chemotherapy consisting of CAV (cyclophosphamide, adriamycin, vincristine) and PE (cisplatin and etoposide) regimens and concurrent high dose thoracic radiotherapy (6,000 cGy); prophylactic brain irradiation (3,000 cGy) was administered to complete responders. Patients with extensive disease received the same alternating chemotherapy but not radiotherapy.

The treatment of metastatic pleural effusion in breast cancer: report of 25 cases.

We report our experience in the treatment of pleural effusion in 25 patients with metastatic breast cancer. Seventeen patients received initial systemic therapy and in 13 of them local intrapleural therapy was subsequently employed; the remaining 8 patients received local therapy only. Several modalities of local treatment were used: intrapleural chemotherapy with thiotepa and 5-fluorouracil; the production of pleural adhesion by the use of chest drainage alone or associated with instillation of sclerosing agents, such as nitrogen mustard or tetracycline.

Lateral thoracic meningocele.

A case of intrathoracic meningocele is reported, and 95 cases from the literature are reviewed. Thoracic meningoceles are usually associated with neurofibromatosis; nevertheless their etiology remains controversial. The authors postulate the role of spinal trauma in some patients and the origin of the meningocele from an abnormal prolongation of a nerve sleeve in nontraumatic cases.
