[Diagnosis and therapeutic pathways in head and neck cancers]. / Parcours de soins du patient présentant un carcinome epidermoïdes des voies aéro-digestives supérieures.

BACKGROUND: Cancers of uppers aero-digestives tracts represent, infrequency, the 5th cancer in the French population. Most of them (about 70%) are diagnosed at an advanced stage (stage III or IV) while they are associated with a poor prognosis (only 40% five year survival). The objective of our study was to analyze the care pathway of patients with cancers of uppers aero-digestives tracts in order to target efforts to improve the survival of these patients. METHODS: It was a descriptive and retrospective study, on medical files, on the health care pathway of patients with cancers of uppers aero-digestives tracts cared in the Head and Neck surgery department of Val de Grâce in Paris and Percy in Clamart between January 2004 and December 2006. The patients were adults with squamous cell carcinoma of uppers aero-digestives tracts. RESULTS: One hundred thirty-eight files of patients were analyzed. Fifty-five percent of patients were diagnosed at an advanced stage. On average patients have waited two months and twenty-one days before consulting a doctor for the first time. The time interval between the specialist consultation and the start of treatment was on average 7 weeks. The overall 5-year survival rate was 61%. CONCLUSION: Squamous cell carcinoma of uppers aero-digestives tracts remains serious and has a poor diagnosis, even in a population with a high social-cultural level. The long time interval before the first consultation may be reduced by improving health education among the general practitioner (primary and secondary prevention), and by establishing health care public campaigns. This would allow earlier diagnosis, more conservative therapeutic opportunities and therefore a better prognosis.

[Deafness in adults. Study of practices in general medicine]. / Les surdités de l'adulte. Etude de pratiques en médecine générale.

INTRODUCTION: Deafness is a sensory disability responsible for communication disorder, sometimes impairing social life. In children, the hearing is an important concern for all stakeholders in early childhood (systematic neonatal screening, etc.). On the other hand, in the adult, it is rarely tested, and patients do consult when their audiometric status is already badly impaired. But their care is all the better if the deafness diagnosis is made early, as for the audio-prosthetic rehabilitation for example. Today, the general practitioner is the first link of the diagnostic and therapeutic management chain. The objective of this study was to evaluate the diagnostic practices of practitioners in front of deafness in adults. SUBJECTS AND METHODS: This prospective study included 74 practitioners based in "Ile de France" interviewed using a multiple choice questionnaire (MCQ) on otoscopic and audiometric diagnostics and a Script Concordance test (SC) on clinical adult deafness situations validated by a 5 experts panel. RESULTS: The obtained average score was 66.35% of correct answers to the MCQ and 47.76% to the SC. CONCLUSIONS: In our study, the surveyed practitioners showed a good level of otoscopic and audiometric diagnosis in the MCQ. However, their answers were not concordant with those of the expert panel in the SC. They have been particularly poorly performing on issues related to functional signs and their use in a given clinical situation, often driving to establish an otoscopic misdiagnosis while their diagnostic recognition of a pathological eardrum in the MCQ was rather good. These results reflect a lack of confidence in their otoscopic diagnosis related to the lack of knowledge of the causes of deafness in adults and their symptoms.

[Rhinocerebral infections in immunosuppressed patients with hematological disorders]. / Infections rhinocérébrales chez l'immunodéprimé en hématologie.

Invasive rhinosinusitis, occurring almost exclusively in immunosuppressed patients, is defined by the presence of local inflammation with vascular and osseous necrosis with extensive soft tissue extension. Imaging and bacteriological and even histological (mycelial filaments) criteria have been established. Because it can evolve to death in patients with hematological disorders, accurate diagnosis is important but difficult to achieve due to the non-specific nature of signs and symptoms. Imaging plays an important role with CT of the paranasal sinuses and MR imaging of the brain for early diagnosis and treatment in order to improve prognosis. We will present the imaging features of three cases of rhinocerebral infections, with two cases of fungal infection and one case of invasive bacterial sinus infection.

[Post-traumatic carotid cavernous fistula: report of two cases]. / Fistule carotido-caverneuse post-traumatique: à propos de deux cas.

Carotid cavernous fistula (CCF) is an abnormal communication between the cavernous sinus and the carotid arterial system. The authors reported the clinical presentation and therapeutic procedure of two cases. The physician has to be aware of this diagnosis when a patient is referred for a posttraumatic exophthalmia. The medical behaviour is multidisciplinary (ENT, ophthalmologist, radiologist and neurosurgeon). The imaging of choice is the angiography but angio-MRI and angio-CT can help to confirm the diagnosis. The endovascular embolization is the treatment of choice. It presents an acceptable risk of complication and a low risk of failure. In this paper the authors report 2 posttraumatic CCF cases treated with success by endovascular embolization.

First assessment of sophrology for the treatment of subjective tinnitus.

OBJECTIVES: To assess (without comparison versus controls) the efficacy of a sophrology protocol adapted to disabling subjective tinnitus, in diminishing the handicap induced by perception of tinnitus. MATERIALS AND METHODS: One hundred and forty consecutive patients, aged 18-83 years, underwent a protocol comprising 6-8 sessions of sophrology over a 2-4 month period. Impact was assessed on pre- to post-treatment progression on the Tinnitus Handicap Inventory (THI), a validated questionnaire measuring handicap induced by tinnitus. RESULTS: Mean THI scores improved, by >20 points in 59.2% of cases (i.e., clinically significant decrease). Improvement was independent of tinnitus duration (>versus<6 months) and origin (acoustic trauma versus emotional shock), and concerned all 3 THI subscales (functional, catastrophic and emotional). CONCLUSION: The present sophrology protocol, dedicated to subjective tinnitus, reduced intrusiveness. Further studies with a control group are needed to confirm efficacy as compared to waiting list or other validated treatments such as cognitive behavioral therapies.

[Cataract surgery and its impact on balance and autonomy in elderly]. / Incidence d'une chirurgie de la cataracte sur l'équilibre et l'autonomie du sujet âgé.

PURPOSE: Cataract is a major cause of visual impairment among elderly. Cataract surgery improves visual afferencies and can have an impact on balance. The present study assessed the impact of cataract surgery upon balance and autonomy in elderly. We realized clinical examinations and objective tests the day before surgery and 2-months later. METHODS: The initial cohort consisted of 66 patients that had to undergo a cataract surgery. Their mean age was 79 +/- 0.5. For logistic reasons, only 33 patients have been completely evaluated before and after surgery. Each patient underwent a history and examination that have assessed autonomy, walking, visual and then cochleo-vestibular functions including bone vibratory test and dynamic computerized posturography (Equitest). RESULTS: After 2 months, cataract surgery had no incidence on balance. The fear of falling has stayed the same whereas the number of falls has been noticeably reduced by surgery. The overall score of Equitest has shown an increase in visual dependence after surgery. Although cataract surgery has no incidence on autonomy, it may improve the quality of life among older people by leisure activities recovery. CONCLUSION: An early physical rehabilitation facilitated by visual improvement after surgery can also prevent visual dependence and autonomy loss. We recommend vestibular rehabilitation in elderly with major visual dependence.

[A rare primary tumor of the cerebellopontine angle: melanotic schwannoma, a pigmented tumor with unpredictable prognosis]. / Une tumeur primitive rare de l'angle pontocérébelleux: le schwannome mélanocytique, une tumeur pigmentée au pronostic réservé

Schwannomas are common ubiquitous benign tumours of the nervous sheaths. Among the various histopathological types, the pigmented schwannoma has to be distinguished from melanoma. We report a case of melanotic schwannoma of the cerebellopontine angle in a 52-year-old man with a slowly progressive cerebellar syndrome since 1978, who presented with a posterior cerebral fossa bleeding. Melanotic schwannoma is a rare form of schwannoma. The diagnosis remains difficult and melanotic schwannoma has been described as a part of the Carney complex. Distinguishing melanotic schwannoma from malignant melanoma is of paramount importance in planning the management, but these two tumours are probably sharing the same origin. It must be distinguished from classic schwannoma because its behaviour is unpredictable, requiring long-term follow-up.

[Reoperation of tumors of the parotid gland. Technical approach and consequences for the 7th cranial nerve. Apropos of 22 cases]. / Reprises chirurgicales des tumeurs de la parotide approche technique et conséquences pour le VII. A propos de 42 cas.

Second or more surgical procedures on parotid are usually difficult and may induce injury on the facial nerve. The authors report their experience about 42 patients. The choice between a total parotidectomy or a surgical excision of a tumor depends of the number of surgical procedure, the type of initial procedure and the histological type of the tumor. Second surgical procedures for a wrong initial histological diagnosis (11 cases) were always a total parotidectomy with facial nerve preservation. The risk of a partial or total facial palsy is higher after several recurrences (3 of 8 cases). The facial nerve had to be resected in 3 of 9 cases of malignant tumors recurrences. The initial treatment of a tumor of the parotid must be radical so it can prevent for further surgical procedures and then avoid a facial nerve injury.

[Positron emission tomography in head and neck oncology]. / Tomographie par émission de positons en oncologie de la tête et du cou.

Defining a therapeutic strategy in oncology requires a substantial amount of imaging data provided by modern techniques. While the description of the lesions and their environment has become very precise, there remains a certain degree of uncertainty concerning tissue typing. Positron emission tomography is a scintigraphy technique which can produce quantitative images of metabolic characteristics. 18F-fluorodeoxyglucose is a tracer allowing an analysis of glucose metabolism known to be highly increased in malignant tissues. Increased uptake is an indication of malignancy with an established correlation with proliferative capacity. The only limitation of the method is the generally weak uptake observed in benign hypermetabolic inflammatory or infectious areas. All stages of the disease are concerned for head and neck cancer patients. Clinical experience to date indicates that PET can be applied most usefully to search or residual disease with a possible differentiation between post-therapeutic fibrosis and viable tumor tissue as well as the identification of early relapse. Study of early response to chemotherapy is also an interesting application. Search for extension can also be improved with this technique allowing both regional and whole body explorations. Positron emission tomography is not widely available in France at the present time so all patients cannot be examined with this technique. Positron emission tomography is an evolving technique with improvements being proposed both in the technique and in tracer elements. Further information will be available with new developments in this non-invasive exploration tool.

[Current aspects of laryngeal tuberculosis: a report of four cases]. / Aspects actuels de la tuberculose laryngée. A propos de 4 cas.

OBJECTIVE: Laryngeal tuberculosis is a rare condition. This new clinical pattern of tuberculosis should be recognized by clinicians. METHODS: We report our experience with four cases of laryngeal tuberculosis. RESULTS: The principal differences in the disease pattern are an increase in the number of cases of primary laryngeal tuberculosis without any evident pulmonary involvement and the declining number of pseudotumor forms with an larger number of nonspecific laryngeal localizations. CONCLUSION: Tuberculosis should be entertained as a possible diagnosis in patients with nonspecific laryngeal disease. The diagnosis is confirmed by identification of granulomatous inflammation and acid-fast bacilli. New culture techniques and molecular biology methods such as polymerase chain reaction allow early identification of Mycobacterium tuberculosis.

[Susac syndrome or microangiopathy of the cochlea, brain and retina]. / Syndrome de Susac ou microangiopathie cochléo-encéphalo-rétinienne.

OBJECTIVES: Susac syndrome, also called SICRET syndrome (small infarction of cochlear, retinal, and encephalic tissue) is a rare condition difficult to diagnose. Sudden deafness may be the inaugural sign. MATERIAL AND METHODS: A female patient developed subacute encephalopathy, bilateral sensorineural hearing loss, and ischemic retinopathy. The patient was given cyclophosphamid and methylprednisolone for six months, followed by prednisone for eight months. RESULTS: Signs of encephalopathy had totally regressed by month 14 and retinal arteries were free of obstruction. Deafness remained unchanged. CONCLUSION: Diagnosis of this microangiopathy involving the inner ear, the brain, and the retina is suggested by the clinical triad and established on the basis of tonal audiometry, fundus examination, fluorescein angiography, examination of the cerebrospinal fluid, magnetic resonance imaging. Multiple sclerosis is the main differential diagnosis. The pathogenesis remains unknown. We observed transient-evoked otoacoustic emissions. There is no consensus concerning treatment. Many advocate combining corticosteroids and immunosuppressors. Otolaryngologists should be aware that an ophthalmological examination is required for patients with central or visual disorders associated with hearing loss.

[Positron emission tomography in head and neck oncology: five cases]. / La tomographie à émission de positons en oncologie ORL. Une revue à propos de 5 cas.

FDG-PET (18-fluoro-desoxyglucose positron emission tomography) is a fonctionnal imaging method based on the high rate of glycolysis in different types of cancer-cells. We report the first five cases where FDG-PET was used in France for head and neck cancers. The results were analyzed on the basis of data reported to date in the literature, leading to a proposal for rational use of this diagnostic available in only a few centers in France. For primary assessment of cervicofacial carcinomas, different imaging techniques such as CT and MRI have improved tumor staging. Although 18-FDG-PET cannot replace these techniques used to monitor size and structural changes in tumors and lymph nodes, it will be helpful in following their metabolic activity. This diagnostic tool consequently is greatly helpful for detection and post-therapeutic evaluation of head and neck carcinomas and their recurrence. 18-FDG-PET is currently under evaluation as a tool for detecting cervical lymph nodes and early assessment of response to chemotherapy.

[Focal infection? Did you say focal infection ... focal infection and uveitis]. / Infection focale? Vous avez dit infection focale ... Infection focale et uvéites.

A chronic seat of infection more often than not situated in the E.N.T. area is responsible for remote pathological symptoms commonly called focal infection. The eye may be a target organ, where focal infection appears in the form of a uveitis. Four clinical observations are reported as demonstration. The transmission mechanism operates through an immune phenomenon from bacterial antigens which engender reactions of hypersensitivity. The E.N.T. specialist must be aware of these symptoms and seek a pharyngeal, sinusal or latent buccodental infection.

[Value of positron-emission tomography in the post-treatment follow-up of epidermoid carcinoma of the head and neck]. / Intérêt de la tomographie par émission de positons dans le suivi post-thérapeutique des carcinomes épidermoïdes de la tête et du cou.

UNLABELLED: This study aimed at pointing out the supply of the positron emission tomography (PET) in the posttherapeutic follow-up of the head and neck squamous cell carcinomas and to determine the best period to perform this test. PATIENTS AND METHODS: Twenty patients have been included in this series, 16 men and 4 women. The PET was performed between 3 and 6 months after the end of all therapy. It systematically included radiation therapy. The results of the PET have been compared with those obtained by histology. The average distance of the follow-up of the patients after the achievement of the test was 11 months. RESULTS: They divided up according to the presence or not of an abnormal fixation on the PET imaging. Negative PETs: eight cases. Among those, a patient showed a metastatic cervical adenopathy at five months. Positive PETs: twelve cases which can be divided into three groups according to the area of the fixation. Primary site: 8 cases, 4 of which false-positive. Cervical lymph nodes: one case. Other sites: three cases. In our series PET had a sensitivity of 87% and a specificity of 67%. CONCLUSION: The PET is an original imaging as it allows a corporal metabolic study at one go. It seems to be very useful in the follow-up of patients who show a head and neck squamous cell carcinoma. The best period to perform it is the third or fourth posttherapeutic month. The high sensitivity is interesting within the context of an early detection of a residual tumour, for it allows to think of a suitable therapy quicker.

[Internal ear injuries in diving: apropos of 16 cases]. / Accidents d'oreille interne en plongée sous marine: a propos de 16 cas.

After the study of 16 observations of inner ear injuries in diving, the authors remind us to the different mechanisms of inner ear's lesions. The principle of treatment depends of these mechanisms. Emergency is to recognize a decompression injury. So, all vestibular disorders must be considered as a decompression injury, as soon as, it was a saturating diving. Hyperbaric oxygenotherapy must be undertaken immediately. Though the symptomatology suggestive of fistula for 4 patients, no surgical exploration was done. The follow-up was marked by spontaneous amelioration, that make think of possible spontaneous cicatrization.

[Incidence of vertigo in diving]. / Incidence des vertiges en plongée sous marine.

Vertigo is relatively common after diving. Although it may be the result of the changes in pressure, it can also be a feature of decompression accidents, of clinical toxicity, simply be a manifestation of altered physiology resulting from immersion in a weightless environment in which all the organs involved in maintaining equilibrium (vestibular system, proprioception and vision) are affected. It seemed to us to be of interest to study the incidence of vertigo in naval divers by means of an anonymous questionnaire. The responses were elicited over a 3 month period from 333 divers. 45 divers reported clinical sensations of vertigo, an incidence of 13.5%. If this figure is related to the number of dives, the incidence falls to 0.06%. No decompression accidents were reported. The main aetiology was barotrauma, 42% being of alternobaric and 36% of pressure type. The remaining aetiologies were sensory illusions in 6% of cases, and other non-ENT causes in 16%. After a review of the physiopatholgy and study of the case hisotries, there is a discussion of the features which allow the aetiology to be determined and treatment planned.

[Traumatic perilymphatic fistula and sports]. / Fistules périlymphatiques traumatiques st sports.

In the past ten years four sportsmen with a traumatic perilymphatic fistula were treated. Three of these four patients were surgically treated: two of them underwent a labyrinthectomy and with one of them, the oval window was grafted. After the analysis of these cases, we have made a study of the literature. Careful attention to the patient history and accurate review of the recurrent vestibulocochlear symptomatology isolate a clinical "audiovestibular syndrome of perilymphatic fistule". There is lack of precise preoperatoire diagnostic test. Nevertheless, entire positionnal audiometric test is a reliable and easy to perform test. The medical management is based on bed rest during a reasonable period. Only patients with significant suggestive symptomatology are surgically explored . They sometimes need destruction of vestibular function without preservation of hearing.

[Laryngeal disorder revealing unrecognized pulmonary tuberculosis]. / Atteinte laryngée révélatrice d'une tuberculose pulmonaire méconnue.

Laryngeal tuberculosis is exceptional and identification in this localization can reveal clinically unrecognized pulmonary tuberculosis. We report two cases illustrating this situation. The pseudo-tumor aspect observed at endoscopy may be wrongly suggestive of neoplasia. Bacteriological examination provides the diagnosis. New methods of genomic diagnosis (Gen-Probe) and culture now allow particularly rapid diagnosis. Outcome is always favorable with standard anti-tuberculosis treatment.

[Lyme disease: a case report]. / Opis przypadku boreliozy.

A male patient aged 38 was complaining from severe musculo-arthral pains and high body temperature of 39 degrees C. He was admitted to the clinical hospital after long and detailed diagnostic procedures--conducted during previous hospitalization, which focused on Plasmocytoma. Serological examinations relating to Lyme disease were undertaken in the clinical hospital and the results appeared positive. The patient received Vibramicin for a prolonged treatment lasting 30 days. Radiological findings showed distraction in both hip joints (especially the right one), with areas of bone erosion, severe osteoporosis and calcifications in periarthral soft tissues. After pharmacological treatment the body temperature normalized and the pain became less severe. The state of the patient's health improved from subjective and objective point of view.
