OBJECTIVE Fine needle aspiration (FNA) has long been recognized as an essential technique for the evaluation of thyroid nodules. Although specific cytological patterns have been recognized, a wide variety of reporting schemes for thyroid FNA results have been adopted. This study reports our experience with a five-category reporting scheme developed in-house(More)
Neurally adjusted ventilatory assist (NAVA) relies on the patient’s electrical activity of the diaphragm (EAdi) for actuating the ventilator. Thus a reliable positioning of the oesophageal EAdi catheter is mandatory. We aimed to evaluate the effects of body position (BP), positive end-expiratory pressure (PEEP) and intra-abdominal pressure (IAP) on catheter(More)
Chromium concentrations in the air were measured in seven different workroom environments, where exposure to water soluble hexavalent or trivalent compounds was expected. Urinary excretion of chromium was measured before and after the same arbitrarily chosen working day. End-of-shift urinary chromium and its increase above pre-exposure levels were closely(More)
INTRODUCTION A reliable prediction of successful weaning from respiratory support may be crucial for the overall outcome of the critically ill patient. The electrical activity of the diaphragm (EAdi) allows one to monitor the patients' respiratory drive and their ability to meet the increased respiratory demand. In this pilot study, we compared the EAdi(More)
AIMS AND BACKGROUND The aim of the study was to assess the activity and the toxicity of cisplatin (DDP) and fluorouracil (FU) administered by continuous infusion as neoadjuvant chemotherapy for patients with stage II-IV, M0 squamous cell carcinoma of the head and neck. METHODS Thirty previously untreated patients were submitted to chemotherapy with DDP(More)
This communication deals with an aspect of occupational hygiene in a factory producing granite cutting diamond wheels by sintering, in moulds, of fine cobalt powder. The factory has been studied between 1988 and 1991; the Department of Preventive and Occupational Medicine of the Local Sanitary Unit of Reggio Emilia has followed the evolution of the local(More)
Fifty-six males workers exposed to rock wool during production, and 20 referents were examined. Exposure, evaluated by personal sampling, ranged from 0.05 to 0.74 fibres/ml (median 0.15). The subjects underwent a medical examination, chest X-ray according to ILO recommendations and pulmonary function tests. In all subjects the serum levels of type III(More)
AIMS AND BACKGROUND Post-irradiation sarcoma (PIS) a rare, late side effect of radiotherapy and, consequently, its natural history is not well known. For this reason, two cases treated between 1975 and 1990 are described. CASE REPORTS The Authors describe one case of malignant fibrous histiocytoma grown in the larynx 111 months after conservative surgery(More)
