Introduction: Myofibroblastic tumours or pulmonary pseudotumours are rare and, though benign, they may become invasive and recur after excision., Case Report: We report the case of a child aged 14, presenting with mild haemoptysis, who had a solitary nodule at the base of the left lung. CT scanning suggested a hypervascular tumour. Fibreoptic bronchoscopy was normal and it was not possible to perform percutaneous biopsy on account of its proximal situation. A lobectomy was performed via a postero-lateral thoracotomy with a successful outcome. Histological examination revealed a myofibroblastic tumour., Conclusion: Recourse to primary surgery is essential to confirm the diagnosis of a myofibroblastic pulmonary tumour. Complete resection is the only guarantee to prevent recurrence.

Introduction: Costo-vertebral echinoccoccus is a rare and serious condition which often presents with neurological complications requiring urgent surgical intervention., Case Report: We report the case of a seven year old girl admitted with a clinical picture suggesting medullary compression secondary to multifocal Hydatid disease. As well as a costo-vertebral cyst with extension into the spinal canal, lesions were also seen in the lower lobe of her right lung and throughout the liver, confirmed by CT scan and by magnetic resonance imaging. A resection of Hydatid material as well as the posterior part of the 4th rib, the transverse process of the 4th costal vertebra and adjacent bone was carried out via a posterolateral thoracotomy. The cyst in the right lung was successfully excised at the same operation. Three months later six hepatic lesions were removed via a subcostal approach again without complication. A scan 23 months later revealed no evidence of residual hydatid disease., Conclusion: This case illustrates the pathophysiological features of costovertebral Hydatid disease and the advantages of an anterior surgical approach.

Cardiac involvement in Whipple's discase is frequent. However, its clinical occurrence without gastrointestinal symptoms is rarely described. Whipple's endocarditis occurs ollen in patients wilh native valves, without underlying, disease. It affects frequently more than one valve h, the same patient. Its clhlical presentation is generally subacute or chronic. Fever and congestive heart failure are fickle. Histological findings on the valves suggest the diagnosis, that con be confirmed by PCR technique. Treatment must be prolonged. We report a case of Whipple's endocarditis revealed by arterial embolisms and fever appeured 3 weeks after the onset.

Objective: Impact of the interval between interruption of aspirin intake and surgery on postoperative bleeding and transfusion in coronary artery bypass graft (CABG), with extracorporeal circulation (ECC)., Study Design: Retrospective study., Patients and Methods: Four hundred and twelve patients having undergone CABG were retrospectively reviewed. Three groups were evaluated according to the length of the interval defined above: Group I (< 3 days), Group II (3-7 days), Group III (> 7 days or without aspirin intake). Postoperative blood loss at 3rd, 6th, 12th, and 24th hour and transfusion requirements were assessed for the 3 groups. Aprotinin (low dose, 2 M KIU) was systematically included in the priming of the ECC circuit., Results: There were no significant differences among groups for weight, size, duration of ECC, and number of bypasses. No significant correlation was noted among the 3 groups for postoperative blood loss and transfusion. Multivariate analysis showed that factors associated to a higher risk of excessive bleeding were ECC duration and number of arterial grafts. Factors associated with a higher risk of transfusion were: emergency, minimum patient temperature during ECC, weight and preoperative haemoglobin level. Aspirine intake was not associated with an increase of bleeding or transfusion., Conclusion: Our study showed that in our practice using systematic low dose of aprotinin when priming the ECC circuit, aspirin did not significantly increase bleeding or transfusion requirements in CABG with ECC, whatever the interval between interruption of aspirin intake and surgery. Consequently, in our practice, aspirin intake is interrupted on hospitalisation, one day before surgery.

The inheritance of telomere-associated restriction fragment length polymorphisms (tel-RFLP) and chromosome-length polymorphisms (CLPs) were criteria used for the identification of strains of Ustilago hordei that form a direct lineage. Teliospore collections of race 8 strains and strains reported to be derived from race 8 through inbreeding were used in these analyses. None of the race 8 strains examined in this study, representing three consecutive inbred generations, was polymorphic for any terminal BamHI and BglII chromosomal loci, nor did they have any apparent CLPs. Strains from a teliospore collection obtained in 1971 and designated 447, representing the first inbred generation of race 8 strains and a shift to increased virulence on cultivar Hannchen, had tel-RFLP arrays indistinguishable from the race 8 strains isolated in this study; and they had no obvious CLPs. Strains from the presumed second inbred generation, the 1279 teliospore line, which was pathogenic on six additional cultivars, had numerous CLPs and a tel-RFLP array that differed from race 8 strains at more than 50% of the terminal chromosomal BamHI and BglII restriction sites. The tel-RFLP array of each 1279 strain was identical and indistinguishable from the arrays of strains representing races 10 and 13, indicating that they share a direct lineage. A race 14 strain, also presumed to be derived from race 8 strains by inbreeding, had a unique tel-RFLP array and an electrophoretic karyotype that distinguished it from all other strains. The tel-RFLP arrays alone eliminate the 1279 and race 14 strains from being direct descendants from race 8 strains by inbreeding and suggest that this approach can identify a strain lineage among other inbred sexually reproducing fungi, or isolates that comprise different asexual clonal populations.
