[Lingual tuberculosis revealing disseminated tuberculosis].

INTRODUCTION: Tuberculous lesions of the oral cavity are uncommon. Most of cases are secondary to pulmonary disease and the primary form is rare. EXEGESIS: We report the case of a 64 year-old man, smoker, presenting a chronic ulcer of the tongue, with anorexia and important weight loss. The biopsy of this ulcer showed granulomatous inflammation and Langhans type giant cells, without necrosis. Ziehl-Nielsen stain was negative. Pulmonary lesions were subsequently detected (chest X-ray, CT-scan) and the disseminated tuberculosis was confirmed by a positive culture with acid-fast bacilli in urine, blood, and pulmonary sample. Antituberculosis treatment resulted in the complete resolution of the oral lesion. CONCLUSION: Biopsy for histopathological diagnosis, acid-fast stains and culture, is essential to determine the exact nature of chronic oral ulceration to distinguish between oral malignancy, infectious (syphilis), traumatic, or aphthous ulcers. Tuberculosis of the tongue is a difficult diagnosis. However it should be searched for because treatment usually results in a rapid recovery.

[Adenocarcinomas of the ethmoid sinus: retrospective analysis of prognostic factors].

OBJECTIVES: Determinate the different prognostic factors of survival in ethmoidal sinus adenocarcinomas (ADK). MATERIAL AND METHODS: 60 patients with ethmoidal sinus ADK. 59 men and one woman. Average of 62.2 years (41-82). Retrospective study between 1985 and 2005. The following data were analyzed: exposure time to wood dust, disease incidence, primary clinical symptoms and ASA score. Radiological data were recovered by tomodensitometry and magnetic resonance imaging. Histological groups were described. TNM classification according to UICC 2002 and Roux/Brasnu was established on clinical and radiological constatations. Different treatments used were analyzed. Estimate of survival rate and impact of different prognostic factors were based on Kaplan-Meier actuarial method and multivariate analysis. RESULTS: Incidence rate was 2.86 patients a year. Exposure average time to wood dust was 25.6 years (2-44). T3/T4 stages were predominant (66.7%). the survival rate was 46.5% at 5 years. The survival rate was significantly superior respectively in T1 and T2 stages than in T3 and T4 stages, and in T4a than in T4b stages. Extension of the lesion to the sphenoid sinus was revealed as a significant bad prognostic factor. The ASA score and the exposure time to wood dust were not identified as statistically significant prognosis factors. CONCLUSION: Survival factors of ethmoïd sinus ADK were T stage and the extension of the tumor to the sphenoid sinus. On the results of this study, we consider that extension in sphenoïd sinus could be include in TNM classification of ethmoïd sinus adenocarcinomas.

[Tympanic paragangliomas: analysis of a nine cases].

OBJECTIVE: The purpose of this work was to evaluate the diagnostic strategy and outcome of patients treated for tympanic paraganglioma. PATIENTS AND METHODS: Nine patients presented with tympanic paraganglioma were treated in our unit from 1996 to 2003. There were eight women and one man, mean age 65 years. Surgery was performed in all nine patients. This retrospective analysis focused on revealing signs, diagnostic tools, surgical procedure for tumor resection, and short-, mid-, and long-term functional outcome. RESULTS: The surgical procedure was well tolerated by all patients. There were no cases of postoperative mastoiditis. None of the patients experienced postoperative dizziness. Total tumor removal was achieved in seven patients. In one patient, incomplete tumor resection was decided in order to preserve facial motion. All patients but one were relieved from their tinnitus in the early postoperative period. In four patients, preoperative hearing levels were worsened by the surgical procedure, essentially through an alteration of preoperative conductive hearing loss. CONCLUSION: MRI is highly contributive to the diagnosis of tympanic paraganglioma, which should be evoked in patients with pulsatile tinnitus. Diagnosis should be established as early as possible to lower the postoperative morbidity. While surgery can provide cure and relieve tinnitus, there is a high risk of auditory deterioration.

[Nasal leishmaniasis: a case report].

OBJECTIVE: To report a nasal leishmaniasis diagnosed by septal perforation biopsy. MATERIAL AND METHODS: We report a case of septal perforation with crusty rhinosinusitis and nasal vestibulitis in a 54-year-old woman with cirrhosis. RESULTS: Mucocartilaginous biopsy revealed a mucosal leishmaniasis. Biological and radiologic findings were normal. Clinical follow-up with anti-parasitical treatment showed a regression of the patient's muco-cutaneous lesion and regression of her hepatic insufficiency. CONCLUSION: Biopsy of septal perforation is a useful diagnostic tool, advocated for differentiate infectious, neoplasic and inflammatory pathology. Leishmaniasis may be evoked in rhinologic pathology.

[Cervical and para-pharyngeal bone tumors: two cases report].

OBJECTIVE: The purpose of the study was to report two cases of cervical and para-pharyngeal bone tumors. MATERIAL AND METHODS: Patients were two 29 and 67-year-old men. Presentation of the lesions included respectively a right cervical mass and a left para-pharyngeal mass. Clinical features and radiological, anatomopathological and therapeutic characteristics of the tumors were retrospectively studied. RESULTS: A cervical approach was made in both cases. Tumor biopsies revealed a vertebral aneurismal cyst and a corporeo-pedicular chordoma respectively. CONCLUSION: Vertebral bone tumors with cervical expression are very uncommon entities. Diagnosis could be systematically evoked in patients with a cervical or para-pharyngeal tumor presenting vertebral lysis.

[Treatment of functional signs of acute maxillary rhinosinusitis in adults. Efficacy and tolerance of administration of oral prednisone for 3 days].

OBJECTIVE: Acute maxillary rhinosinusitis (AMRS) is a pathology in which the pain is often severe and requires appropriate treatment. Although the use of antibiotics is widely documented, the interest of short cycles of corticosteroids in the treatment of the functional manifestations of AMRS is based on professional experience. The aim of this study was to assess the efficacy and tolerance to prednisone administered for 3 days in addition to antibiotherapy in patients presenting with an AMRS. METHOD: This was a double blind, randomised study in parallel groups and controlled versus a placebo, involving patients aged over 18, presenting with an AMRS confirmed by X-ray and endoscopy, having developed less than 5 days and complaining of spontaneous pain assessed as >or=50 millimetres on a visual analog scale (VAS). Together with cefpodoxime, the patients received either prednisone (0.8 to 1.2 mg/kg) for 3 days or a placebo. The primary efficacy endpoint was the mean of the differences versus the baseline value of pain (MPID - mean pain intensity difference) assessed on the VAS from Day 1 to Day 3. The secondary endpoints assessed were the mean of the differences in intensity of nasal obstruction, assessed in the same way as the MPID, the time lapse before the orally expressed relief of the pain (PRID - pain reflief intensity difference) and the administration of paracetamol during the first 3 days. RESULTS: 289 patients (placebo 147, prednisone 142) were assessable for analysis in intent-to-treat (ITT). The global spontaneous pain on inclusion, measured by a VAS was of 73.0 +/- 14.1 mm. The assessments made during the first 3 days of treatment showed a statistically significant difference in favour of the prednisone group regarding MPID: - 4.82 mm (CI 95% -9.25; -0.40) (p=0.03), nasal obstruction - 5.0 mm (CI 95% -9.1; -0.8) (p=0.02) and consumption of paracetamol (p=0.03). There was no difference between the two groups after the end of the antibiotherapy. The tolerance measured throughout the study was comparable between the two groups. CONCLUSION: This study clearly showed the efficacy of a short course of oral prednisone (3 days), versus a placebo, in the treatment of the functional signs of acute maxillary rhinosinusitis with severe pain in adults in addition to an appropriate antibiotic treatment.

[Intraparotid facial nerve schwannoma: a case report].

OBJECTIVE: We describe a case of intraparotid facial nerve schwannoma. About sixty patients with intraparotid tumors have been reported in the literature. MATERIAL AND METHODS: A 89-year-old female patient presented with a history of progressive facial palsy and a left intraparotid mass. The mass was removed by parotidectomy for definitive diagnosis and treatment. We reviewed the findings in comparison with data in the literature. RESULTS: The well-encapsulated tumor arose from the superior branch of the intraparotid facial nerve. As the tumor could not be dissected from the nerve, a segment of facial nerve was sacrificed and repaired by interposing a greater auricular nerve. The final pathological diagnosis was schwannoma arising from the facial nerve. DISCUSSION: This case illustrates the clinical and pathologic features of intraparatid facial nerve schwannoma and points out the pitfalls of diagnosis and treatment. Consensus has recognized total resection surgery with facial nerve sacrifice as the most reasonable treatment for these tumors. We discuss the currently accepted management approach as well as the different treatment modalities for recovering facial function.

[Idiopathic sudden deafness].

PURPOSE: Sudden idiopathic deafness is a sensorineural hearing loss with no recognized causes at the time of onset. The impairment site is usually localized in the cochlea, but some cases of retrocochlear lesions (e.g., cerebellopontine angle tumors, degenerative neural diseases, neuraxial ischemic lesions) can induce sensorineural deafness. The medical management of patients presenting with sudden deafness aims at detecting a causal mechanism, and at administering emergency therapeutic drugs. The diagnosis of idiopathic sudden deafness can be definitely made when no causes are found. Usually, the impairing mechanism involves the cochlea. The pathophysiology of this sensorineural alteration is still unknown. It is most likely that several mechanisms are associated together, their common point being an impairment to the feedback loop of the organ of Corti. CURRENT KNOWLEDGE AND KEY POINTS: It is very likely that reactivation of neurotropic viruses and/or cochlear ischemia are frequent etiologies. Whatever the cause, the treatment is to be administered urgently, and consists of a high-dose corticotherapy at the least. Other treatments have never really proven to be effective. It is secondarily checked that no retrocochlear pathological processes, such as a cerebellopontine angle tumor, is present, in particular in young people. FUTURE PROSPECTS AND PROJECTS: One of the current objectives is to determine when cochlear ischemia is involved, in a mini-invasive manner, such as with laser Doppler flowmetry, so that the treatment can be optimized. From a therapeutic point of view, early acoustic protection has been proven to be effective in cases of cochlear ischemia in small laboratory animals. Its efficacy in case of sudden deafness, non-exclusive of other causes than ischemia, is being assessed in a multicentric project.

[Magnetic Resonance Imaging in Facial Bell's Palsy].

UNLABELLED: The meaning of facial nerve enhancement by gadolinium-enhanced magnetic resonanca imaging (MRI) in Bell's palsy is very discussed. Aim of our study was to define the radiological data in facial Bell's palsy and to correlate them with clinical data. PATIENTS AND METHODS: 34 patients with facial Bell's palsy were studied prospectively. Each patient had two gadolinium-enhanced MRI. The first MRI was realized during the first ten days. The second MRI was realized three months later. Two patients with facial nerve enhancement localized on the third portion was not clinically normalized at 3 months. Facial nerve enhancement and his precise location was noted. RESULTS: Facial nerve enhancement was noted in 71,5% on first MRI and in 30% on second MRI. Gadolinium-enhancement was predominantly noted on the Fundus. No patients with facial nerve enhancement persisting at three months was clinically normalized at one month. CONCLUSION: Facial nerve enhancement localized on the fundus and/or on the third portion, persisting at three months, could be consider as a negative landmark of fast clinical facial recuperation.

[Analysis of nasal and exhaled nitric oxide concentration in nasal polyposis].

UNLABELLED: Nitric oxide (NO) is implicated in the pathophysiology of inflammatory airway diseases. It has been identified as a potential marker of airway inflammation. OBJECTIVE: The purpose of the study was to assess the concentrations of nasal NO in upper and lower airways in nasal polyposis patients. PATIENTS: 18 nasal polyposis patients (14 men, 4 women) and 21 control subjects (7 men, 14 women), all non asthmatic non smokers, without respiratory infections were prospectively studied. METHODS: They included nasal obstruction scoring, nasal endoscopic grading, allergy testing, nasal cytology, flow-volume spirometry and measurement of nasal (NNO) and exhaled NO (ENO) concentrations. NO was measured by a chemiluminescence NO Analyser (Sievers 280). NNO was analysed by aspiration with a constant flow of 3 l/mn. ENO was analysed during a slow expiration (50 ml/s) against a constant resistance of 10 cm H2O. RESULTS: NNO was significantly (p<0,001) decreased in NP group (596.4 +/- 102.06 ppb) compared to control group (2 251.6 +/- 288.6 ppb). ENO was significantly (p<0.05) increased in NP group (45.4 +/- 14.1 ppb) compared to control group (11.2 +/- 1.16 ppb). NNO and ENO were not significantly different between atopic and non-atopic NP patients. NNO concentrations was inversely correlated with the values of nasal endoscopic grading. No correlation was found between NNO concentrations and respectively nasal obstruction scoring and eosinophil count in nasal mucosa. CONCLUSION: Further studies are necessary to understand the pathophysiology of decreasing NNO and increasing ENO in nasal polyposis. In particular, ENO could be consider as a biologic marker of lower airway inflammation in nasal polyposis.

[Anatomy of the vestibulo-acoustico-facial neurovascular pedicle. Importance of therapeutic management of vestibular schwannomas].

A perfect knowledge of the anatomy of the vestibuloacusticofacial pedicle is required to preserve hearing and facial functions during cerebellopontine angle surgery for vestibular schwannoma. A clarification of the anatomy of this pedicle, in particular of its blood supply, is presented here, based on a review of the available literature, as well as on the author's data issued from anatomical dissections on latex-injected fresh specimens, and from radiological images of the cerebellopontine angle. The blood supply to the vestibuloacusticofacial bundle arises from the meatal loop of the anterior inferior cerebellar artery most often exhibited at the porus of the internal acoustical meatus. The labyrinthine artery is particularly exposed to injury between the cochlear and facial nerves. In addition, dissection in between these two nerves is likely to sever vessels directed to these nerves even though the labyrinthine artery is not interrupted. Thus, aside from a direct injury to the labyrinth, auditory function can be impaired through two distinct ischemic lesion types. Although the facial nerve is supplied through three main arterial systems (from the labyrinthine, the middle meningeal, and the stylomastoid arteries), its labyrinthine portion is more likely to suffer from ischemic damage as it is only supplied by meatal arteries. A refinement of our anatomical knowledge of the vestibuloacusticofacial pedicle, from a functional point of view, could arise from laser Doppler measurements of labyrinthine and facial blood flow during surgery, in an attempt to improve our functional preservation rate during therapeutic procedures for vestibular schwannoma.

[Analysis of eosinophilia and ECP levels in blood and nasal secretions of 119 nasal polyposis patients].

OBJECTIVE: The aim of this prospective study was to determine eosinophilia and ECP (Eosinophilic Cationic Protein) levels in blood and in nasal secretions of patients with nasal polyposis (NP). PATIENTS: 119 patients with NP were prospectively studied. The control group included 25 patients. METHODS: They included: questionnaire about asthma and intolerance to aspirin; nasal endosopic grading; nasal symptoms scoring; allergy testing; measurements of serum and nasal values of eosinophilia expressed as a percentage; measurements of serum and nasal values of ECP expressed in ng/ml; the Spearman correlation test, the T series and Khideux tests were used in the statistical analysis. RESULTS: In NP group, 66 were asthmatic (As) and 53 non asthmatics (NAs), 40 were atopic (ATo), and 79 were non atopic (NAto). Values of nasal eosinophilia and nasal ECP in NP patients were significantly higher (respectively 40.7+/-35.6% and 22.8+/-48.0 ng/ml) than the control group (respectively 3.0+/-14% and 2.1+/-3.6 ng/ml). Nasal and serum eosinophilia values in asthmatic patients (As) (respectively 47+/-36% and 7.6+/-6.3%) were significantly higher (p<0.05) than in non asthmatic patients (NAs) (respectively 32.6+/-33.8% and 4.6+/-3.1%). No difference was found in nasal and serum ECP values between asthmatic and non asthmatic patients. Nasal eosinophilia values were significantly correlated (p=0.02) with nasal scoring in NP patients. No correlation was found between nasal ECP and serum ECP values and clinical scoring. CONCLUSION: Nasal eosinophilia and nasal ECP values are significantly increased in NP. Nasal eosinophilia seems to be a relevant biological marker of clinical severity (association with asthma and a high clinical score) in NP patients. By contrast, nasal ECP cannot be consider as a marker of clinical severity.

[Early otorhinolaryngological manifestations of Wegener's granulomatosis. Analysis of 21 patients].

UNLABELLED: Wegener's Granulomatosis (WG) is a necrotizing granulomatous vasculitis that has a strong affinity for the upper respiratory tract. OBJECTIVE: To retrospectively study the clinical features of otorhinolaryngological manifestations from 21 WG patients. PATIENTS: Eleven men and 10 women were studied with respectively a mean age of 62.7 (23-79) and 63.9 (53-73). METHODS: Otorhinolaryngological manifestations were recorded before and during the course of WG. RESULTS: Upper respiratory tract involvement occurred in 81% of cases (17/21 patients) and was isolated in 42.8% of cases (9/21 patients). Nasosinusal manifestations occurred in 71.4% of cases (15/21) before and at the time of GW diagnosis. They included bilateral sinusitis (7 cases), nasal crusting (6 cases), purulent rhinorrhea (5 cases), epistaxis (4 cases), nasal ulcers (2 cases), nasal congestion with obstruction (3 cases) and 4 cases of nose deformity (saddle nose or oedema). Otologic manifestations occurred in 28.5% of cases and were never isolated. They included otitis media (3 cases), sudden hearing loss (3 cases), tinnitus (1 case), facial palsy (1 case) and 2 cases of chondritis. Pharyngolaryngotracheal manifestations occurred in 33.3% of cases (7/21). Diagnosis of GW was based on positive ANCA test (95.2% of cases), presence of biologic inflammatory parameters (76% of cases) and histological features. 29 biopsies from nasosinusal lesions on 17 patients were made. 44.8% of the biopsies were contributive with at least one histologic feature of the combination including vasculitis, necrosis and granulomatous inflammation. The best contributive site of biopsy was the paranasal sinus. CONCLUSION: We report that otorhinolaryngological manifestations occurred in 81% of cases before and at the time of GW diagnosis. These findings indicate that otorhinolaryngologists have a central role to play in early diagnosis of the disease.

[Intrapetrous aneurysms of internal carotid artery: therapeutic considerations: two cases].

Two cases of internal carotid artery aneurysm arising within the petrous bone are described, bringing up to 56 the number of such cases reported to date in the medical literature scanned through Medline. The first case presented as a moderately bleeding tumor of the petrous apex, while the second was revealed by a massive otorrhage. In both cases a pulsatile nasopharyngeal mass was associated with otorrhage. The treatment required in both cases the aneurysm to be embolized in extreme emergency. One patient suffered transient hemiplegia and aphasia that completely recovered, while the second eventually died, although the carotid occlusion had been well tolerated in the first two weeks that followed this procedure. From their own experience and a literature review, we can emphasize the need for arterial extra-intracranial bypass before an aneurysm embolization be proposed, since the neurological issue following internal carotid occlusion cannot be predicted.

[Middle ear metastasis. One case report].

UNLABELLED: Metastatic carcinoma involving the middle ear space is a rare entity that is little described in the literature. The number of cases seems to be increasing. It is usually recognized that palliative treatment as the most reasonable treatment for this tumors. CASE REPORT: A 59-year-old female patient presented with a history of a metastatic carcinoma involving the middle ear space and mastoid. This metastase occurred one year late in the course of a bladder cancer. Presentation of the lesion included otorrhea and facial palsy complicated by headache and bilateral visual loss in relation with lateral sinus thrombophlebitis and intracranial hypertension. Diffuses metastases in the skeletal system were demonstrated by pretreatment investigations. Treatment was only palliative chemotherapy. Outcome was fatal two months after onset of symptoms. DISCUSSION: This case illustrates the clinical and pathological features of this tumor and the pitfalls of diagnosis and treatment. We will discuss the current accepted management and the difference after diagnosis modalities for this type of metastatic tumor.

Efficacy and tolerability of budesonide aqueous nasal spray treatment in patients with nasal polyps.

OBJECTIVE: To assess the efficacy and tolerability of once-daily treatment with budesonide aqueous nasal spray in patients with nasal polyps. DESIGN: Randomized, double-blind, placebo-controlled, parallel-group study. SETTING: Sixteen hospital clinics. PATIENTS: One hundred eighty-three patients with moderate-sized nasal polyps causing clinically significant symptoms during a 1-week run-in period. INTERVENTIONS: Patients were randomized to receive 1 of the following 4 budesonide aqueous nasal spray treatments: 128 microg once daily in the morning and placebo in the evening, 128 microg twice daily, 256 microg once daily in the morning and placebo in the evening, or placebo for 8 weeks. Nasal polyp size was scored and peak nasal inspiratory flow was measured at clinic visits at the beginning and end of the run-in period and after 4 and 8 weeks' treatment. Patients recorded daily peak nasal inspiratory flow, symptom scores (ie, blocked nose, runny nose, and sneezing) and sense of smell on diary cards. MAIN OUTCOME MEASURES: Mean change in nasal polyp size at the end of treatment; mean changes in combined and individual symptom scores. RESULTS: All doses of budesonide aqueous nasal spray significantly (P<.01) reduced polyp size; no significant differences were noted between the 4 treatment groups. The mean improvement in clinic peak nasal inspiratory flow at 8 weeks was 65.9 L/min with budesonide aqueous nasal spray, 128 microg twice daily; 71.6 L/min with budesonide aqueous nasal spray, 256 microg once daily; and 54.6 L/min with budesonide aqueous nasal spray, 128 microg once daily (all P<.001 vs placebo). Combined and individual symptom scores and sense of smell improved significantly in all budesonide-treated groups; the effect on symptoms became apparent within 1 to 2 days of the first dose. Budesonide aqueous nasal spray was well tolerated. CONCLUSIONS: Doses of budesonide aqueous nasal spray, 128 microg once daily, were found to be effective in the treatment of nasal polyps, and doses of budesonide aqueous nasal spray, 256 microg once daily, did not show any significant additional efficacy.

Concomitant type I thyroplasty and thoracic operations for lung cancer: preventing respiratory complications associated with vagus or recurrent laryngeal nerve injury.

OBJECTIVES: We sought to prevent postoperative swallowing disorder, aspiration, and sputum retention in cases of recurrent laryngeal or vagus nerve section occurring during lung cancer resection. METHODS: In 14 of 25 consecutive patients, type I thyroplasty and thoracic operations were performed during the same period of anesthesia. All patients had a preoperative laryngeal computed tomographic scan providing us with indispensable measurements for vocal fold medialization under general anesthesia (ie, without intraoperative phonatory control). Nine remaining patients had a type I thyroplasty delayed from thoracic operations because of intraoperative doubt about laryngeal innervation injury, and 2 did not need a laryngeal operation. Main postoperative records consisted of swallowing ability, respiratory complications, and quality of voice. RESULTS: No swallowing disorder, aspiration, or sputum retention occurred in cases of concomitant laryngeal and thoracic operations. Of these 14 patients, a single case (7%) of major complication (vocal fold overmedialization) occurred and required an early and successful revision thyroplasty; one case of cervical hematoma that did not require surgical drainage was considered a minor complication (7%). Twelve (86%) patients who underwent the concomitant association of both operations were fully satisfied with their quality of voice. CONCLUSIONS: Type I thyroplasty and thoracic operation can be advantageously associated in case of injury to laryngeal motor innervation to prevent postoperative swallowing disability and dramatic respiratory complications.
