Spiramycin concentrations in lung tissue were studied in patients undergoing pulmonary surgical procedures. The first group of six patients received 500 mg spiramycin iv 16 h before surgery and 500 mg at anaesthetic induction (total 1 g). The second group of six patients received three doses of 500 mg spiramycin iv 24, 16 and 8 h before surgery, and 500 mg at anaesthetic induction (total 2 g). Samples were taken from lung tissue, pleura, fat tissue and muscle. In group 1, the mean lung tissue concentration of spiramycin was 1.15 +/- 0.14 mg/kg and 7.99 +/- 2.02 mg/kg in group 2 (P less than 0.02). The differences in concentration in pleura, fat tissue and muscle samples between treatment groups 1 and 2 were not statistically significant.
Echocardiography provides a firm diagnosis of pericardial effusion and evaluates its repercussions on the cardiac cavities. The images obtained with two-dimensional echocardiography are of such quality that the anatomical lesions can be analyzed, but the predictive value of this examination for the aetiological diagnosis has not yet been established. To investigate this point we have compared the images recorded in 39 episodes of pericardial disease with the corresponding anatomical data provided by surgery (n = 38)) or necropsy (n = 1) less than 48 hours after the ultrasonic examination. In one case, the purely solid nature of the pericardial content, suspected on the presence of an echo-filled cavity with adherent membranes, was confirmed at surgery. Conversely, the totally or partly liquid nature of the effusion was ascertained whenever the two pericardial membranes were separated by an echo-free cavity in at least one portion of the region examined, and there was no false-positive result (n = 38). The images obtained could be compared with the anatomical lesions in 28 out of 38 cases of partly or totally liquid pericarditis. The pericardial cavity was entirely echo-free in 12 of these cases, and this was confirmed by the anatomical examination, except in one case where epicardial nodules were found at surgery. Abnormal intrapericardial images were detected in the other 16 echocardiographic examinations, viz.: round masses in 2 cases, linear echoes in 2 cases and mattress-like deposits in 12 cases. In 9 of these 16 cases corresponding intrapericardial formations were discovered at surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

Timentin (ticarcillin + clavulanic acid) and cefamandole were compared in 484 patients undergoing elective thoracic or vascular surgery. Two hundred and forty eight patients received three 3 g/200 mg injections of Timentin and 236 patients received three 0.75 g injections of cefamandole. The patients were evaluated at discharge. Among the 248 patients given Timentin, only six (2.4%) had a post-operative infection, while nine (3.8%) of the 236 patients given cefamandole had a post-operative infection. There was no statistically significant difference between the two treatment regimes. This comparative study shows that Timentin may be used for antibiotic prophylaxis of clean vascular or thoracic surgery.
The in vitro activity of ticarcillin in combination with clavulanic acid was tested, by disc diffusion, against 1,380 clinical bacterial isolates and was compared with that of ticarcillin alone. 83.8% of the isolates were susceptible to ticarcillin + clavulanic acid, whereas 56.6% were susceptible to ticarcillin alone. Minimal inhibitory concentrations (MIC) of ticarcillin in the presence of 4 micrograms/ml of clavulanic acid were determined against 157 ticarcillin resistant (MIC greater than 128 micrograms/ml) but ticarcillin + clavulanic acid susceptible strains of Gram negative bacilli and against 20 strains of beta-lactamase producing Staphylococcus aureus. With the addition of clavulanic acid, MICs of ticarcillin were respectively less than or equal to 16 micrograms/ml and less than or equal to 64 micrograms/ml for 50 and 90% of the Gram negative bacilli. All the Staphylococcus aureus were inhibited by concentrations of ticarcillin less than or equal to 1 microgram/ml.
The subject of whether an optimal duration of prophylactic antibiotic therapy exists was evaluated by comparing results of short and medium-term treatment in aseptic surgery during a double-blind, randomized, prospective trial in 507 patients undergoing vascular or thoracic operations. Patients were randomly allocated to receive either 3 injections of cefamandole: at induction of anesthesia and after 4 and 10 hours (251 cases) or 8 injections of the same antibiotic: at induction of anesthesia, after 4 hours and then every 6 hours up to 40 hours (256 cases). Evaluation on discharge showed that among the 251 patients receiving 3 injections, 21 (8.33%) were infected while in the group treated with 8 injections (256 cases) 25 (9.8%) were infected. The X2 was 0.25 and there is a lack of statistically significant difference between treatments. Duration of prophylactic antibiotic therapy can be shortened, without loss of efficacy in thoracic or vascular aseptic surgery, to reduce selection of resistant germs and to lower costs.

A case of fatal haematemesis due to erosion of a retro-oesophageal right subclavian artery by a nasogastric tube is reported. In view of this exceptional but extremely serious complication, no oesophageal tube should be used in patients known to have this abnormal anatomical arrangement. Systematic treatment of aberrant subclavian arteries should perhaps be considered when it can be performed during thoracic surgery.

Tracheo-bronchial ruptures are serious complications of thoracic trauma. The authors report their experience of 18 cases: 3 tracheal ruptures, 3 tears in the tracheal or bronchial membrane, 11 unilateral bronchial ruptures and 1 bilateral bronchial rupture. Diagnostic endoscopy was performed immediately in 9 cases, with a delay of 2 to 3 days in 6 cases and with a longer delay (15th, 23rd and 25th days) in 3 cases. The treatment was non-operative in the 3 cases with membranous tears. The other patients were operated by resection of the contused area and end-to-end anastomosis of the ruptured extremities: within 24 hours following the diagnosis in 10 cases, and after a delay in the 5 other cases. The post-operative course was uncomplicated in 13 cases; 1 patient developed a bronchial stenosis requiring pneumonectomy and 4 patients died, including 2 from infective lesions due to delay in the diagnosis.
The authors report a case of adventitial cyst of the abdominal aorta. This would seem to be the first time that a cyst has been reported in the literature with this localization. A 54 year old female patient was treated surgically for a suspected aneurysm of the abdominal aorta. Her antecedents included syphilis treated with bismuth. The condition began with a lumbago with no clearly defined etiology. An abdominal X-ray without preparation visualized a calcified abdominal tumor in a retroperitoneal position, apparently attached to the aorta. Arteriography showed that the tumor was excluded from the circulation. Surgical exploration of the aorta demonstrated a cystic tumor, which was resected. A review of the literature concerning the pathology of arterial cysts shows no previous cases of aortic cyst. On the other hand, references to identical anomalies of the iliac, femoral, popliteal and radial arteries provide grounds for discussion of the etiology of this aortic disease. The macroscopic data and histological studies suggest a phenomenon of cystic degeneration rather than a constitutional anomaly of the artery, or, in this particular case, an anomaly connected with syphilitic lesions.

Fifty-five uretero-neocystostomies were carried out using a technique derived from the Lich-Gregoir technique. Tightness is ensured anastomosis and burying over the vesical dome, with minimal vesical opening; the anti-reflux system is effective. Urinary complication of this ureter transplantation method are now rare, in our series, only two complications due to necrosis of the ureteral segment were observed. This technique could be used in all obliterations of the ureter, whether accidental or by necessity, located near the bladder.
