[Thoracic trauma: incidence, social and economic costs, educational opportunities. 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.

[Post-operative analgesia in thoracic surgery: physiopathological features, therapeutic framework and methodologies]. / Analgesia post-operatoria in chirurgia toracica: aspetti fisiopatologici, basi terapeutiche e metodi.

Pain after surgery is a major handicap for patients as it bounds and decreases ability for spontaneous movement, cough and deep breathing, aiding the onset of complications and invalidating the recovery capabilities of operated patients. In thoracic surgery, the need to compile and employ guidelines for post-surgical pain management has become a pressing requirement in recent years. Currently available protocols include several options of treatment that are frequently a subject in the most recent scientific papers and play a key role, as they constitute the framework upon which building with changes and fixes that take account of incidental circumstances, in relation to both patients and surgery, again for both the organizational and structural features of the surgical environment. Purpose of this job is a thorough analysis of post-operating analgesic treatments for thoracic surgery, introducing the most effective ones currently available as for channels and procedures of administration, as well as possible side effects or complications.

[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.

[Malignant pleural mesothelioma: early diagnosis and multimodality management]. / Diagnosi precoce e terapie integrate del mesotelioma pleurico maligno.

Malignant pleural mesothelioma (MPM) is a cancer with a poor prognosis, and its incidence increase, mainly as a result of exposure to asbestos. Universally acknowledged therapeutic approaches still don't exist at the moment, because of its refractory behaviour to all standard therapies; treatment protocols inclusive of either surgery, radiotherapy or chemotherapy have been largely employed, but usually with little impact on survival. For potentially operable pleural mesotheliomas new treatments tend to combine surgery both with new chemotherapy drugs and radiotherapy, in order to improve remarkably survival rates in selected cases. Other approaches, i.e. palliative, proved to be useful in the treatment of two major symptoms, namely dyspnea and thoracic pain. In this work the Authors are reporting their experience with malignant pleural mesothelioma, stressing the role of videothoracoscopy in the early diagnosis, weighing the radical cancer resection option and the effectiveness of multimodal treatment.

Function of the heater: the dead horse arum revisited.

The dead horse arum, Helicodiceros muscivorus, is a conspicuous, foul smelling and thermogenic plant of the Araceae family. This Mediterranean arum lily copies several aspects of a carcass in order to attract carrion blowflies, which are subsequently exploited as unrewarded pollinators. We have previously shown that this plant exhibits a highly accurate olfactory carrion mimicry, which serves to attract the blowflies. In this study, we have investigated the role of thermogeny in the arum. We show that the thermogeny has a direct effect on the pollinators, altering their behaviour. By manipulating heat and odour release of the plant, we can show that the heat, produced along the appendix, is important to lure the flies to this structure, which is vital as the flies from the appendix are more prone to enter the trap chamber that houses the female and male florets. This study provides rare evidence for a direct functional role of thermogeny.
