  ABSTRACT: The principal goal of an early identification program is to identify hearing impairment present at birth, in order to effect appropriate intervention as early as possible. Although recent research provides some evidence for the value of transient evoked otoacoustic emissions (TEOAEs) in neonate hearing screening, data are needed from large-scale clinical evaluations about the value of using TEOAEs for screening not only high-risk but also healthy neonates. A cohort of 1,421 neonates (2,842 ears) from the well-baby nursery was screened with TEOAEs in a 2-stage process. Neonates were referred from the first test prior to being discharged from the hospital. Those who failed were rescreened before the end of the first month. Those who did not pass the second-stage TEOAE screening were referred for diagnostic audiological evaluation for confirmation of hearing loss. Neonates transferred to a neonatal intensive care unit were not included in this study. Two neonates with bilateral sensorineural hearing loss of >40 dB hearing level were identified from this cohort. This study demonstrates the feasibility and the limitations of using TEOAEs as a universal hearing screening tool for all neonates. It confirms that the prevalence of hearing impairment in neonates has to be taken into account, even in a group of children without high-risk criteria. In France, a prevalence of 1.4 per 1,000 would represent 1,000 deaf children born every year, with reference to about 700,000 births per year. This study suggests that such universal screening programs would substantially increase the rate of early-identified infants with significant hearing impairment.

  ABSTRACT: A series of 23 patients with sphenoid disease were seen between 1992 and 1997. The most common symptom was headache. This headache was found to be nonspecific. Cranial nerve abnormalities were found in two patients. The different types of radiolographic images were analyzed, and compared with the surgical diagnosis. Twenty-one patients underwent surgical exploration by intranasal endoscopic sphenoidotomy. This approach allowed drainage and inspection of the sinus.

• Article: [Carcinosarcoma of the submaxillary gland].

  [show abstract] [hide abstract]
  ABSTRACT: Salivary gland carcinosarcoma is a rare neoplasm, with a poor prognosis, that should not be confused with the more common carcinoma ex-pleomorphic adenoma, in which the epithelial component alone is malignant. The authors report one case of carcinosarcoma of the submandibular gland, with no previous history of pre-existent tumor. The tumor exhibited two intermingled and very atypical cellular components, one undifferentiated and the other with a chondroid pattern. Immunostaining with epithelial markers in the undifferentiated area allowed to distinguish this tumor from salivary gland sarcomas. In addition, the positivity for EMA, vimentin, and S100 protein in the two predominant components suggested a common origin for the different tumoral cell types, and led to discuss the nomenclature and the still unclarified cellular origin of these tumors.

• Article: Characteristics of transient-evoked otoacoustic emissions (TEOES) in neonates.

  [show abstract] [hide abstract]
  ABSTRACT: Transient-evoked otoacoustic emissions (TEOEs) were measured in 1164 ears from 582 neonates without any risk of hearing impairment in order to define basic characteristics useful in deciding if TEOEs could be considered as "normal" in a screening test. Five neonates had no recordable TEOE and ABR thresholds greater than 30 dBnHL. Technical conditions have been analysed using the intensity of the click stimulation, the time necessary to record TEOEs, and the noise floor in the external ear canal (i.e. A-B magnitude). The TEOE magnitude varied between 6.6 dB SPL and 38 dB SPL (mean = 21.75 dB SPL). Only 5% of the tested neonates had a TEOE magnitude lower than 7.75 dB SPL. The TEOE magnitude for the right ear of a neonate was statistically different from those recorded in the left ear (22.4 dB SPL versus 21 dB SPL). The mean TEOE magnitude for male ears was statistically different from those recorded in female ears (21.4 dB SPL versus 22.1 dB SPL).

  ABSTRACT: Among a series of 520 parotidectomies performed between 1975 and 1995, we observed 88 cases of malignancy (17%). For this study, we excluded skin cancers which had invaded the parotid and glandular metastases of squamous cell carcinoma, malignant melanoma or kidney cancers, retaining only tumors with a glandular origin and lymphomas. Thus defined, our series comprised 60 patients, i.e. 12% of the operated parodids (31 confirmed cancers, 18 tumors with intermediary malignancy, including several in which the pathology report confirmed malignancy, and 11 lymphomas). We examined therapeutic management by histology and compared the outcomes. Relation with the facial nerve are discussed. Prognosis depends on histology, tumor stage and treatment.

  ABSTRACT: The histological examination of the salivary gland tumors is a very important step in the diagnostic approach of the lesions, on which depends the success of therapeutic outcome. Some surprises may occur; four examples were reported. In one case the lesion was not a tumor but a tuberculous lymphadenitis; another showed a Destombes Rosai Dorfman syndrome. Two other cases were found to be unusual tumors: a carcinosarcoma of the submandibular gland and a metastasis of a Merkel carcinoma in the submandibular gland.

• Article: [Deafness in the neonatal period: basis for screening].

  ABSTRACT: Deafness must be recognized in infancy in order to reduce auditory disability to a minimum. To achieve this, it is important to implement screening programmes as soon after birth as possible. In the United States, the Joint Committee on Infant Hearing recommended in 1982 that identification of hearing loss should be screened in the neonatal period. This early detection is now considered critical for optimal rehabilitative outcome. This paper presents the "state of art" neonatal screening principles and procedures. In France, neonatal screening programs for auditory dysfunction are not consistent with these principles. Evoked otoacoustic emissions represent an important advance in screening for hearing loss in normal neonates and babies from neonatal intensive care units. This method records very low intensity sound energy released by the cochlea in response to a brief sound stimulation. These otoacoustic emissions show promise as a rapid, cost-effective means of quickly discharging all babies with normal peripherical auditory systems.

  ABSTRACT: Evoked otoacoustic emissions (EOE) were recorded with ILO88 in a group of 254 neonates (n = 508 ears) in order to determine the normative data. In this study, it was found that: (i) the mean EOE amplitude was 20.2 dB SPL, (ii) the EOE amplitude of the right ear was significantly higher than those of the left ear, (iii) the mean time necessary to record EOE in both ears was around three minutes, and (iv) EOE spectrum was large (mean = 638-5,611 Hertz). These data permit to precise the clinical interest of EOE for screening auditory function in neonates.

  [show abstract] [hide abstract]
  ABSTRACT: Periostitis ossificans and sclerosing osteomyelitis are rare subtypes of non suppurative chronic osteomyelitis in which there is, additionally, a proliferation of periosteum leading to bony deposition secondary to a mild chronic infection making their diagnosis difficult. The authors report two clinical cases and try to release criteria helping to discern them because the prognosis and therapeutic management of these affections are different.

  ABSTRACT: This study compared the results of the CT scan of the paranasal sinuses in nasal polyposis patients before and after a topical vasoconstrictor application on the nasal mucosa. No change have been observed either on the maxillary and ethmoidal sinuses, or the middle meatus. On the other hand, an important retraction was observed on the nasal mucosa, in particular on the inferior turbinate. Then, the application of a topical vasoconstrictor on the nasal mucosa does not seem necessary in order to explore the sinuses in patients with nasal polyposis.

  ABSTRACT: The authors report the case of a 75 years old insulin dependent diabetic man presenting a malignant otitis externa with facial nerve paralysis. Despite prolonged, adequate parenteral antibiotic therapy, the patient's clinical status did not improve. The addition of hyperbaric oxygen as a complementary treatment was followed by the regression of clinical signs and the resolution of infection. Based upon a review of the literature, the authors discuss the indications for this therapy and the problems involved in defining the criteria of cure in malignant otitis externa.

• Article: Functional endoscopic sinus surgery for isolated sphenoid sinus disease.

  ABSTRACT: This article reviews 12 cases of isolated sphenoid sinus disease: chronic inflammatory sinusitis (7), mucoceles (2), aspergillus lesions (2), and isolated polyp (1). Criteria for diagnosis were based on clinical symptoms, nasal endoscopic evaluation, and computed tomography (CT). Magnetic resonance imaging was used only in cases of bone erosion and when patients presented with vision problems. All patients were treated by functional endoscopic sphenoidotomy. Any postoperative complications were noted. The reported good results, on the basis of regression of functional symptoms and with nasal endoscopic and CT evaluation, suggest that intranasal sphenoidotomy under endoscopic control is a safe and effective method of treatment of nonmalignant isolated sphenoid disease. The mean follow-up is 26 months.
