Angiotensin-converting enzyme in sarcoidosis: a British study.

Serum angiotensin-converting enzyme (ACE) activity was measured in 18 healthy controls, 26 patients with active sarcoidosis, 13 patients with inactive sarcoidosis and seven patients with extensive tuberculosis. The serum ACE activity showed no significant difference between male and female in the control or sarcoidosis groups. There was no correlation between ACE activity and age except in the female active-sarcoid group. ACE activity in the active-sarcoid group was significantly higher than in the control, inactive-sarcoid and tuberculosis groups. The ACE activities at Stages I, II and III of the disease were not significantly different.

[Lung cancer in Lebanon. Experience at the l'Hôtel-Dieu de France in Beirut].

All lung cancer cases admitted in our hospital from the 1st of January 1979 to the 31st of December 1995 were reviewed to allow for the study of the "behaviour" of the disease in Lebanon. A total of 386 cases included 87.5% males and 12.5% females. Mean age was 60 years. 87.3% were smokers. Squamous cell carcinoma was the most frequent histologic type (37.3%) and predominant in men. Adenocarcinoma was more frequent in women (50% v/s 29.9%). Patients often consulted their physician after delays of several months. Diagnosis is commonly confirmed by bronchoscopy. Transthoracic needle aspiration has become, since 1990, a very useful procedure for diagnosis of peripheral lesions with a sensitivity of 90.6%. Metastases are recorded in 30.9% of cases. Histological type distribution and advanced cancer stages found in our study are similar to that encountered in extensive international studies over the last few decades.

[Triple filling plasty in Clagett thoracostomy].

Clagett's thoracostomy is a widely used procedure in the initial treatment of postpneumonectomy empyema. We describe in this paper an original one-step operation of thoracic filling after empyema sterilization. The triple plasty includes an apical thoracoplasty limited to the first 3 ribs, a pedicle flap of the latissimus dorsi transferred inside the thoracic cavity, and an upper translation of the diaphragm to the 4th rib in order to reduce residual pleural space. Three patients were operated and followed up clinically (for 20, 29, and 30 months), and radiologically with a MRI on the 12th month. Complete tissue healing and loss of all residual space was observed in all patients. We therefore recommend the use of this technique rather than thoracic wall coverage procedures.

Augmentation of the sinus floor with mandibular bone block and simultaneous implantation: a 6-year clinical investigation.

Between 1991 and 1995, 216 sinus-lift procedures were accomplished as part of a clinical study. The study involved placing 467 implants in the atrophic posterior maxillae of 142 female and 74 male patients. The initial bone height at the implant site was between 1 and 5 mm. The implants were supported subantrally with bone block grafts harvested from the retromolar or symphysis areas of the mandible. Perforations of the maxillary sinus membrane were observed in 51 patients; these were repaired with fibrin adhesive. The spaces remaining above the bone graft were filled with various materials. A total of 28 implants failed. All the remaining implants were deemed successfully osseointegrated, based on radiographic and clinical (including periodontal health) criteria. No patients experienced maxillary sinus complications. Clinically and radiographically, the best bone regeneration was observed in those patients in whom the surgically created space was completely grafted with autogenous bone that included a high percentage of resorption-resistant cortical bone. In those patients having bone grafts harvested from the mandibular symphysis, none of their facial profiles were adversely affected; however, some patients experienced neurosensory deficits involving the mandibular anterior incisors and adjacent alveolar mucosa. Occasionally, these symptoms persisted for up to 1 year following the procedure.
