Sinusite récidivante due à Schizophyllum commune. À propos de deux nouveaux cas

Schizophyllum commune is a basidiomycete fungus of the agaricomycetes class. It is usually found in forest habitats in the form of saprophytic and lignicolous fungus. Its implication in human pathology is rare, only 50 clinical cases among which 18 cases of sinusitis have been described in the last 60 years. We report two new cases of sinusitis. The first was a 57-year-old woman with chronic sinusitis and the second was a 56-year-old man suffering from an allergic sinusitis. This basidiomycete was identified after isolation in culture both by macroscopic and microscopic aspect and molecular biology. In both cases, evacuation and drainage by surgical debridment were sufficient to obtain a cure. The main bioclinical characteristics of Schizophyllum commune infection are provided

Mometasone and desloratadine additive effect on eosinophil survival and cytokine secretion from epithelial cells

Although antihistamines and topical corticosteroids are used in combination to treat allergic rhinitis, their additive effect has not been yet demonstrated. The aim was investigate the antiinflammatory additive effect of mometasone and desloratadine on cytokine and sICAM-1 secretion by epithelial cells, and on eosinophil survival stimulated by human epithelial cells secretions from nasal mucosa and polyps. Methods Epithelial cells obtained from nasal mucosa or polyps were stimulated with 10% fetal bovine serum in presence of mometasone (10-11M-10-5M) with/without desloratadine (10-5M). Cytokine and sICAM-1 concentrations in supernatants were measured by ELISA. Peripheral blood eosinophils were incubated during 4 days with epithelial cell secretions with (10-11M-10-5M) and/or desloratadine (10-5M) and survival assessed by Trypan blue. Results are expressed as percentage (mean ± SEM) compared to control. Results Fetal bovine serum stimulated IL-6, IL-8, GM-CSF and sICAM-1 secretion. In mucosa and polyp epithelial cells, mometasone inhibited this induced secretion while desloratadine inhibited IL-6 and IL-8. The combination of 10-5M desloratadine and 10-9M mometasone reduced IL-6 secretion (48 ± 11%, p < 0.05) greater extent than mometasone alone (68 ± 10%) compared to control (100%). Epithelial cell secretions induced eosinophil survival from day 1 to 4, this effect being inhibited by mometasone. At day 4, the combination of mometasone (10-11M) and desloratadine (10-5M) provoked an increased inhibition of eosinophil survival induced by cell secretions (27 ± 5%, p < 0.01) than mometasone (44 ± 7%) or desloratadine (46 ± 7%) alone. Conclusions These results suggest that the combination of desloratadine and mometasone furoate have a greater antinflammatory effect in an in vitro model of eosinophil inflammation than those drugs administered alone

Gardner's syndrome presenting with a fibromatous tumour of the parotid

International audienceINTRODUCTION:Gardner's syndrome is the association of familial adenomatous polyposis (FAP) with an anaphase promoting complex (APC) gene mutation and several extradigestive manifestations: osteomas, epidermal cysts and desmoid tumours. Only 2 cases of FAP associated with parotid tumour have been reported in the literature: one carcinoma and one pleomorphic adenoma.CASE REPORT:We report the case of a 23-year-old man with Gardner's syndrome presenting with a fibromatous tumour of the left parotid gland. The other clinical manifestations were an osteoma of the skull base and a mesentery desmoid tumour. Left total parotidectomy was performed, followed by gastroscopy and colonoscopy, demonstrating numerous colonic adenomas. Genetic analysis revealed an APC gene mutation, confirming the diagnosis. Total prophylactic colectomy was performed.CONCLUSIONS:This is the first reported case of Gardner's syndrome associated with a fibromatous tumour of the parotid. Early management of FAP is essential to prevent colorectal cancer that occurs in 100% of untreated cases. The rarity of this syndrome and the parotid site can lead to delayed diagnosis

Endoscopic treatment of antrochoanal polyps

The antrochoanal polyp (Killian polyp) is an infrequent, benign neoplasm, which arises from the maxillary sinus to reach the ipsilateral choana. The treatment of this disease is essentially surgical, by means of a wide antrostomy. The aim of the study was to compare the results obtained on 23 consecutive cases of antrochoanal polyps endoscopically treated between February 1997 and January 2000 with those reported in the literature, with particular regard to the surgical technique adopted, the histological features, the patterns of its development and the clinical outcomes. The histology revealed in most of the cases a cystic aspect surrounded by edematous stroma. In all cases the polyp emerged from the middle meatus, mostly starting from the upper-lateral (zygomatic) wall of the antrum. All patients were endoscopically followed-up for an average period of 39 months (17–61). We observed two recurrences, both in pediatric cases who evidently underwent an incomplete surgical removal of antral mucosa at its inferior aspect, probably due to the fear of damaging the teeth buds. We did not observe any postsurgical complication. Our data indicate the endoscopic middle meatal antrostomy as the optimal approach, also for the revision cases and in children

Endoscopic transnasal transseptal pituitary surgery

International audiencePituitary surgery is performed via a transsphenoidal approach in the vast majority of cases according to various methods that have changed over the years. A microscopic transseptal approach via a sublabial mucosal incision or a nasal mucosal incision has also been extensively used. An endoscopic transnasal approach was first described in the 1990's, followed by the concept of a microscopic transseptal approach and an endoscopic strictly endonasal approach. We use an entirely endoscopic transseptal transsphenoidal approach via an incision in the nasal mucosa for both access and tumour resection. This procedure has a number of advantages: strictly midline approach to the sella turcica, large operative field, no interference between instruments and a low rate of nasal complications

Interest of video-assisted minimally invasive surgery in primary hyperparathyroidism

International audienceINTRODUCTION:Surgery is the only radical and definitive treatment for primary hyperparathyroidism. Exploration of the four parathyroid sites is giving way to minimally invasive techniques. The present study sought to compare two minimally invasive parathyroidectomy techniques, by classical cervicotomy (MIP-C) and by video-assistance (MIP-VA), in terms of success rate, complications rate, operating time, and patient and community physician satisfaction.MATERIALS AND METHOD:A non-randomized retrospective comparative study included 112 patients presenting with primary hyperparathyroidism with identified parathyroid adenoma, operated on between January 2005 and October 2010. The two groups were constituted according to the surgeons' habitual practice: 54 cases of MIP-VA and 58 of MIP-C.RESULTS:Results for MIP-VA and MIP-C were respectively: success, 96.3% vs. 100% (P=0.09); mean scar size, 1.47 vs. 3.43cm (P<0.01); hypocalcemia, 2 vs. 3 cases (P=0.1); theater time, 94.25 vs. 76min (P=0.02); and postoperative stay, 1.08 vs. 1.37 days (P=0.07). Patient satisfaction was comparable between groups, while 93.3% of community physicians found MIP-VA preferable to MIP-C, although only 39.3% had known the MIP-VA technique.CONCLUSION:With efficacy, morbidity and patient satisfaction comparable to classical surgery, MIP-VA significantly reduced cervicotomy size and hospital stay. Community physicians considered it to be preferable to MIP-C
