Hearing screening objective is the development of an universal screening. With that purpose, new hand-held system of Otoaccoustic Emissions have been designed, which are easier to perform and to interpret the results, to detect hearing loss disordersas soon as possible. To validate the hand-held systems of Otoaccoustic Emissions in the hearing screening, we have compared the results of the tests with Otoaccoustic Emissions clinic systems and tonal audiometry in two groups of population: new-borns and hearing-loss adults aged between 16 and 56. Our study showed that the hearing screening results in children with hand-held system were similar to classic Otoaccoustic Emissions system, but there were more than 40% of adult hearing losses not detected with this system. These results can invalidate the test.

[Medium and large acoustic neurinomas with normal tonal audiometry at the moment of diagnosis].

INTRODUCTION: Early diagnosis of an acoustic neurinoma for any possible treatment is important, especially in view of the relationship between surgical morbidity and the size of the tumour. The commonest presenting symptom of these tumors is unilateral perceptive deafness. However, between 4 and 12% are diagnosed before deafness occurs, although they may be large in size. Therefore one should remember other symptoms which lead to suspicion of these tumors, and have diagnostic guidelines available to allow the earliest possible detection. PATIENTS AND METHODS: We report four cases of acoustic neurinoma or vestibular schwannoma of medium or large size in which audiological studies did not at first give rise to suspicion of the presence of this tumour, since audition was considered to be normal at conversation frequencies (500 to 3,000 Hertz) for the age of the patient or who had an audiometry curve with symmetrical deafness in both ears. CONCLUSION: We evaluated the diagnostic importance of the tests done and compared the results with data published in the literature.

[Effectiveness of venlafaxine in the treatment of alcohol dependence with comorbid depression].

INTRODUCTION: There are no conclusive data on the effectiveness of antidepressant drugs in the treatment of comorbid cases of alcohol dependence and depression. OBJECTIVES: To determine the effectiveness of venlafaxine on depression and on severity (need of treatment) of alcohol dependence and related problems. METHODS: Observational, open-label, multicenter, 24-week follow-up study. PATIENTS: 90 outpatients with diagnosis of alcohol dependence and associated major depression disorder (DSMIV criteria). OUTCOMES MEASURES: the Hamilton Rating Scale for Depression (HAM-D17), European Addiction Severity Index (EuropASI) and Clinical Global Impression, severity and improvement subscales, (CGI-S and CGI-I). Evaluations were performed at baseline and at weeks 2, 4, 8 and 24. RESULTS: Mean age 44.94+/-9.74 years; 73.3 % man. HAM-D17 mean scores significantly decreased from baseline (24.85+/-5.94) to week 24 (5.976+/-4.68) and at each of the follow-up visits vs previous visit (p < 0.0005). Significant decreases from baseline to week 24 were obtained in four areas of EuropASI: medical status (2.12+/-2.45 to 1.07+/-1.68), alcohol use (5.29+/-2.24 to 3.04+/-2.35), family/ social relationships (3.68+/-2.36 to 1.71+/-2.06) and psychiatric status (5.61+/-1.81 to 2.67+/-2.03). Tolerance was excellent or good in 76.7% of the patients. CONCLUSIONS: Venlafaxine demonstrated to be effective in the treatment of depressive alcoholic patients. Furthermore, it seems to be useful to decrease the severity of problems related with the alcohol use.

[Scanning electron microscope study of chemically disinfected endodontic files].

Forty stainless steel endodontic files were observed at scanning electron microscopy after being subjected to ten disinfection cycles of 10 minutes each one, immersed in different chemical disinfectants. Corrosion was not observed on the surface of the files in circumstances that this study was made.

[Lucilia sericata infestation of the skin openings for the bone traction device in lengthening of the tibia: apropos of a case].

Fly larvae are responsible for animal disease well known by veterinarians. However, their finding in humans in nontropical countries is a rarity. Recently, we have found several larvae of Lucilia sericata in an achondroplastic child during the phase of lengthening of both tibiae with osteotax. We think that the myasis diagnosed in our patient is the first such case reported in the literature. For the time being, it should be considered a fortuitous finding and not as a complication of surgery.
