OBJECTIVES: To determine the factors that modify the measures of voice onset time (VOT) as acoustic parameter in operated cleft palate children. The voice of cleft palate patient is defined by the generation of an abnormal intraoral pression. This doesn't allow the normal generation of voiceless plosives consonants and produces an increased VOT. Acoustic analysis of voice quantifies these parameters. In this study we observed an increased VOT if the patient hadn't got a normal teeth occlusion and a normal soft palate function. Also VOT measures were influenced by cleft lip and delay in beginning of ortodoncy. Hearing loss is associated with increased VOT. Our results are based in a correct sample and statistical analysis by multiple lineal regression.

Objetivos. Determinar los factores que modifican las características del parámetro acústico tiempo de inicio de sonoridad vocálica (VOT) en pacientes intervenidos de FP y/o labiopalatina. Las características acústicas del habla del paciente fisurado vienen determinadas por la dificultad de crear una presión intraoral adecuada. Esto dificulta la emisión de fonemas oclusivos sordos y supone una modificación de los parámetros acústicos del habla de estos pacientes y en concreto una prolongación del VOT. Mediante análisis acústico pretendemos cuantificar este parámetro. En este estudio observamos una prolongación del VOT en casos de maloclusión dental y paladar blando insuficiente. Asimismo está influido por la presencia de labio fisurado y un retraso en la edad de inicio de la ortodoncia. El deterioro de la audición prolonga el VOT. Los resultados vienen avalados por un correcto muestreo y un análisis estadístico mediante regresión lineal múltiple (AU)

A case of permanent pulsatile tinnitus of the left ear in a patient with hypertriglyceridemia is reported. The combined radiological study with computed tomography, magnetic resonance imaging, and digital angiography excluded a glomus tumor and revealed an enlarged, high-position jugular bulb with slow blood flow. Causes of pulsatile tinnitus are discussed. We conclude that imaging techniques play a major role in the diagnosis of head and neck vascular abnormalities.

A cytomorphodensitometric study was made by analysis of the computerised image of the germinative and intermediate epithelial layers in a sample of five specimens of cholesteatoma and the corresponding skin from the external auditory canal. A morphometric variable corresponding to the nuclear area was determined and densitometric variables equivalent to the relative quantity of nuclear DNA were determined. Within the germinative layers of the cholesteatoma epithelium, we observed larger nuclei and more relative DNA per nucleus. The average densitometric values were in the range of 2C-4C, which is indicative of a greater cellular population in S phase in the cholesteatoma than in the skin.

Epithelial proliferation in colesteatoma and its influence on the subepithelial inflammatory reaction was studied using morphometry and nuclear photometry of specimens. Twenty specimens of colesteatoma and 15 specimens of skin from the external auditory canal were examined. Nuclear content was greater in the basal cells of colesteatoma epithelium than in the basal cells of external auditory canal epithelium, suggesting increased proliferative activity. This activity was found to be reted to the inflammatory infiltrate of the conjunctive tissue and varied in different specimens.

BACKGROUND: The Epstein-Barr virus (EBV) is related with nasopharyngeal carcinoma (NPC) in that, in this neoplasm, high levels of antibodies are found vs different EBV antigens. METHODS: The determinations of IgG and IgA type antibodies were evaluated vs capsid antigens (VCA) and early antigen (EA) of the EBV by indirect immunofluorescence in 14 patients diagnosed with NPC, in 12 patients with other tumors of the head and neck and in 61 blood donors. RESULTS: The detection of IgA type antibodies with a sensitivity and specificity of 100% and 92% for the VCA antigen and of 86% and 100% for the EA antigen are the most useful tests in the early diagnosis of nasopharyngeal carcinoma. The determination of IgG type antibodies were of a more limited usefulness with sensitivities and specificities of 86% and 67% for IgG anti-VCA and 100% and 83% of IgG anti-EA. CONCLUSIONS: The detection of antibodies vs VCA and EA antigens is useful in the differential diagnosis of NPC with other tumors of the head and neck.
