Eosinophilic granuloma of the temporal bone: radiological approach in the pediatric patient.

Eosinophilic granuloma is one of the three clinical variants of Histiocytosis-X (eosinophilic granuloma, Hand-Schüller-Christian and Letterer-Siwe disease). Involvement of the temporal bone is relatively rare and initially silent. However, it can erode the mastoid cortex, destroy the tegmen and extend into the cranial vault, as well as erode the semicircular canals or cochlea. It usually presents as an aural polyp or postauricular swelling. Chronic otorrhea is what brings the patient to the ORL-Clinic. It is frequently confused with infectious diseases or neoplastic conditions of the temporal bone. In this paper we report 6 cases of eosinophilic granuloma in the temporal bone, discuss the plain radiological and CT findings and review the literature.

[Use of the CO2 laser in the emergency treatment of dyspnea in laryngeal cancer]. / Utilisation du laser CO2 dans le traitement d'urgence des dyspnées des cancers du larynx.

Occlusion of the larynx of neoplastic origin was treated by CO2 laser in seven patients between Marc 1982 and April 1983. Temporary tracheotomy was avoided in all 7 cases but treatment had to be repeated in two patients. Specific anesthetic techniques necessary when using the laser in hypercapneic patients are described, and the advantages, limitations and complications of this therapy are discussed.

[Cancer of the mobile tongue. Therapeutic development and results]. / Cancers de la langue mobile. Evolution des thérapeutiques et résultats.

The authors analyse the results of treatment of 84 squamous cell carcinomas of the mobile portion of the tongue treated between 1961 and 1982. 64% of the patients treated were Stage I or II. The local recurrence rate was 13% at 5 years (6/43) for T1, T2. Recurrences were more frequent after interstitial radium therapy (17% at 5 years: 5/28) than after partial glossectomy performed at the outset (6.6% : 1.15). The treatment of stage NO remains controversial. The frequency of lymph node recurrences remains proportional to lymph node involvement by histology (NO, N-: no recurrences; NO, N+: 18.1%: 6/33) but seemed to be independent of the initial treatment of the regional nodes: no treatment, neck dissection with or without subsequent external radiotherapy. It is important to emphasize that lymph node recurrences contralateral to the tumour always occurred in the presence of initial homolateral lymphadenopathy with capsular rupture. Other oncological failures were frequent (35% : 20/56) at 5 years, grouping together visceral metastases (14.3% : 8/56) and second primary cancers in the upper respiratory/digestive tract (21.4% : 12/56).
