[Interest of PET/CT scan fusion to assess mandible involvement in oral cavity and oro pharyngeal carcinomas].

UNLABELLED: The aim of the study is to assess mandible involvement in oral cavity and oropharyngeal carcinomas. OBJECTIVE: To evaluate interest of fusion of Positron Emission Tomography (PET) with Computed Tomography scan (CT scan). METHOD: Eight patients were included in this prospective study. Each patient underwent PET and CT scan of the head and neck before surgery including tumorectomy and mandibulectomy. We compared results of PET- CT fusion with histologic examinations. RESULTS: Oral cavity (6), oropharyngeal (2) carcinoma: Mandibular invasion was suspected by PET-CT in 3 cases, but was confirmed in histological examination in only 2 cases. In 5 cases, PET-CT did not find mandibular invasion; this was confirmed in histological examination in all cases. Sensibility of PET-CT fusion was 100%, specificity was 83%. Positive predictive value was 66% and negative predictive value was 100%. DISCUSSION: PET-CT fusion provided maximal sensitivity. Specificity was better than for MRI but less than CT-scan. There were no false negatives and the false positive rate was 33%. CONCLUSION: PET-CT fusion is interesting to predict mandible involvement. Further studies are necessary to confirm these preliminary results.

[Asthma and polyposis].

For many years, the association between asthma and naso-sinus pathology has been noted in the literature. The role of sinus infections on the triggering or aggravation of asthma has been well established. More recently attention has been drawn to the association of the chronic inflammatory rhino-sinus pathologies such as polyposis, with asthmatic illness. Its research and identification are essential in care of the asthmatic patient, since recent work has shown the value of control of polyposis for the stability and improvement of the asthmatic illness. The authors report and analyse the diagnostic and therapeutic methods for polyposis in asthmatics.

[Laryngeal schwannoma. Diagnostic and therapeutic approach. Apropos of 2 cases].

Laryngeal schwannoma is an uncommon benign tumor. We report two clinical cases and discuss the different types of clinical symptoms revealing the tumor. Difficulties encountered in obtaining a histological diagnosis are presented. The contribution of imaging is also analyzed according to the different surgical techniques used to manage the tumor depending on its size and localization. We stress the importance of long-term follow-up as recurrences may occur several years after surgical removal.

Fluorescent-antibody method useful for detecting viable but nonculturable Salmonella spp. in chlorinated wastewater.

An indirect fluorescent-antibody (IFA) technique, which employed adsorbed Behring polyvalent I O antiserum, was used to detect Salmonella spp. in environmental water systems. The IFA method used in this study detected 95% of Salmonella serotypes encountered in human infections in France, with a sensitivity threshold of 7.5 x 10(3) bacteria per ml of wastewater. Specificity was assessed by testing IFA against Salmonella-free seawater and a variety of bacteria other than Salmonella spp. When used to examine raw and chlorinated wastewater over a 2-month period, the IFA method was successful in detecting Salmonella spp. in all 12 of the samples examined, with total numbers determined to be 4.5 x 10(5) to 3.3 x 10(7) salmonellae per 100 ml. In comparison, for the same samples, enumeration by culture, using the most-probable-number technique, was effective in detecting Salmonella spp. in only four of eight raw-water samples and one of four chlorinated water samples tested. Three samples were further tested by using the direct viable count procedure combined with IFA and results showed that 5 to 31.5% of the Salmonella spp. enumerated by this method in chlorinated water were substrate responsive.
