[Bilateral and multiple traumatic pulmonary pseudo-cysts: a case report]. / Pneumatocele post-traumatico: a proposito di un caso a localizzazione multipla bilaterale.

Traumatic pulmonary pseudocyst is a very rare consequence of blunt chest trauma characterized by formation of cystic like parenchymal lesions. Generally multiple and bilateral distribution is more rare than a single localization. The computed tomography (CT) scan has an higher diagnostic value compared with conventional chest X-ray. Prognosis of traumatic pseudocysts is generally good with benign clinical course and spontaneous resolution within several months. However initial strictly patient follow-up is necessary to early discover and treat potentially severe complications. Utility of chest magnetic resonance imaging (MRI) to exclude potentially severe infectious complications is described. Any complications required percutaneous drainage or surgical resection.

[Etiology, pathophysiology and management of post-traumatic pneumomediastinum: our experience]. / Pneumomediastino post-traumatico: meccanismi eziopatogenetici e management diagnostico-terapeutico. Nostra esperienza.

The Authors reported the cases of posttraumatic pneumomediastinum came to their observation over the past 8 years. The etiology, pathophysiology, diagnosis, treatment and blunt injures eventually associated are discussed. Conclude that in the absence of associated injuries the treatment and the course of post-traumatic pneumomediastinum are the same that spontaneous pneumomediastinum.

Experience on the last eight years of Thoracic Surgical Unit of Messina University]. / Il trauma toracico: incidenza, costi socio-economici, ricaduta didattico-formativa. Esperienza della Cattedra di Chirurgia Toracica dell'Università di Messina negli ultimi otto anni.

The Authors, after extensive introduction on the incidence, etiology, classification, pathophysiology, possible complications, diagnosis and treatment of thoracic trauma, relate their experience on the last eight years, stressing the diagnostic and therapeutic strategy in management of trauma simple and complicated and assessing finally serious social impact of these pathologies and the educational opportunities provided.

["Intentionally" limited pulmonary resection versus lobectomy for the treatment of peripheral stage IA non-small cell lung cancers]. / Resezioni polmonari limitate "intenzionali" versus lobectomie nel trattamento dei tumori polmonari periferici non microcitomi allo stadio IA.

BACKGROUND: The purpose of this study is to assess, through the retrospective analysis of our experience and the literature review, whether the limited pulmonary resection is comparable to lobectomy for treatment of the peripheral stage IA (T1N0M0) non-small cell lung cancers (NSCLC), in terms of oncologic radicality, survival and rate of local, regional and systemic recurrences. Moreover it has been considered the impact of the limited resections in comparison with the lobar resections on the postoperative pulmonary function. PATIENTS AND METHODS: We have analyzed a consecutive series of 36 patients, 28 men and 8 women, of inclusive age among the 61 to 81 years (average 73 years), who underwent surgical resection from January 2000 to December 2003 for T1N0M0 peripheral NSCLC; 11 limited resections and 25 lobectomies have been performed. Comparatively survival and recurrences (follow-up period of 3-5 years) are been analyzed, as well as the pulmonary function tests at 1 year after surgery. RESULTS: The 3-year and 5-year survivals were 88% and 82% in the patient's group underwent to limited resection , 93% and 88% in the patient's group underwent to lobectomy. Postoperative local recurrence was noted in 1 patient (9%) of the first group and in 1 patient (4%) of the second group. One year after surgery was noted a moderate decline in the forced expiratory volume in 1 second (FEV1) and in the diffusing capacity for carbon monoxide (DLCO) in the patients who underwent to lobar resection, whereas in the patient's group submitted to limited resection was observed a substantial maintenance, except for the DLCO, of the preoperative pulmonary function tests. CONCLUSIONS: Our limited experience, according to the actual tendencies of the literature, show that the limited pulmonary resections, in selected patients with peripheral stage IA NSCLC, represents a valid alternative to lobectomy in terms of survival and recurrence's rate, also determining a lower decrement of the postoperative pulmonary function. Therefore the segmentectomy can be considered, in such cases, the gold-standard procedure even if the patient is able to bear a wider resection.

[Indications, surgical strategies and evaluation of prognostic factors in the treatment of pulmonary metastases]. / Indicazioni, strategie chirurgiche e studio dei fattori prognostici nel trattamento delle metastasi polmonari.

Pulmonary metastases resection is a method universally accepted in selected patients. Long-term survival reaches good levels after complete resection of lung metastases independently of primary tumour histology. The Authors emphasizes literature data; they report data of their experience no statistically significant but useful for valuation of results. They discuss of advantages vs disadvantages of the surgical procedures. In conclusion they believe metastasectomy is a safe treatment of pulmonary metastases.

[Surgical treatment of hydatid cysts]. / Trattamento chirurgico delle cisti idatidee complicate.

Hydatidosis represents a form of helminthic zoonosis with a stronger medical, social and economic impact. It is endemic in some areas of the world including Mediterranean countries, and therefore Italy. The disease is often diagnosed in an advanced phase, due to the poor symptomatology in the early stages. The best treatment is surgery. Emergency surgery is similar to elective surgery, though in some cases is preferable only a drainage procedure until the stabilization of the genreal and local conditions of the patient allow a radical intervention. The Authors report on their five year experience of surgical treatment of compliated pulmonar hydatidosis pointing out that exeresis must be aimed at preserving pulmonar function as much as possible.

[Combined video-thoracoscopic, surgical and endovascular treatment in a case of ascites and recurrent bilateral pleural effusion]. / Trattamento combinato video-toracoscopico, chirurgico ed endovascolare in un caso con ascite e versamento pleurico bilaterale recidivante.

Among recurrent pleural effusions a role of remarkable importance is held by those combined with ascitis due to the difficulty of their treatment, even using widely tested techniques. The incidence of such pathology varies from 4% to 6% of patients suffering from cirrhotic pathology, reaching 10% in cases with advanced illnesses. Pleural effusions involve the right emithorax more frequently than the left one, but it can show up bilaterally too. Its etiopathogenesis is tied up to the direct passage of ascitic liquid into the chest and, during the past years, numerous theories have been described to explain this migration. The Authors report the case of a patient with interesting considerations for the diagnostic difficulties and the peculiarity of the treatment performed.
