[Descriptive epidemiology of hospital interconsultations carried out at the ORL Service for a year in the San Millan-San Pedro Hospital Complex].

UNLABELLED: 391 requests of collaboration to our ENT Department during 1996 have been collected. Twelve variables were analysed: number of request, age, sex, date of emission, type (ordinary, with priority, urgent), time elapsed from emission until valuation of the patient, source, reason's request, pathology, complementary tests, treatment and destination (discharge, re-examination during admission or as an outpatient and admission to ENT-Service). RESULTS: 1,58 request were attended per working day, 80 percent were resolved during the first 48 hours, the Internal Medicine Department was the most frequent source, fever without focus or recalcitrant was the most frequent reason from Paediatric Department. We report the epidemiologic features of the most frequent variables.

[Variability in the digital voice analysis depending on the analyzed vocal, in normal patients and in patients with dysphonia].

UNLABELLED: The aim of this study is to decide which of Spanish's 5 vowels is the most suitable for the analysis of the voice by means of the program Dr. Speech 3.0. We assessed 98 patients: 51 normal subjects and 47 hoarse patients (34 polyps, 7 nodules, 2 hyperfunctional dysphonia, 4 other pathologies) before and after following a surgical and/or speech therapy. The methodology of the study included: protocolized questionnaire, ENT examination, perceptual evaluation of the hoarse voices and physical analysis of the 5 sustained vowels. Jitter, shimmer, NNE and HNR in the voice varied depending on the analyzed vowel and from normal subjects to hoarse patients. NNE and HNR for vowels [o] and [u] was higher than for [a], such differences were statistically significant (p < 0.001). Shimmer for vowels [o] and [u] was lower than shimmer for [a] in hoarse patients (p < 0.05). Jitter for [a] was higher than jitter for the other vowels in normal patients. All algorithms improveded with surgical and/or speech therapy. Especially levels of noise for vowels [a] [e] and [o] presented statiscally significant improvements (p < 0.001), shimmer for [a] and [e] (p < 0.001) and jitter for [e] (p < 0.01). The hoarse patients presented values more pathological than the normal subjects, especially jitter for vowels [a] [e] and [o] (p < 0.001), shimmer for [a] [e] [i] and [u] (p < 0.001) and level of noise for [a] [e] [o] and [u] (p < 0.001). CONCLUSION: The analysis of vowel [e] presented higher r than [a] when correlated with perceptual evaluation of voice or with voice quality that gave us Dr. Speech 3.0. Also, the [e] is the best vowel to express the improvements of jitter, shimmer and level of noise of hoarse patients after following surgical and/or speech therapy.

[Tracheobronchial foreign body in the laryngectomized patient].

We report a case of aspiration of a foreign body in the left tracheobronchial tree occurring in a laryngectomy, operated one year previously. The accident presented by fracture of the inner tracheostomy cannula. The literature is reviewed in order to explain possible causes of tracheostomy tube components breakage and to suggest methods for preventing such complications.

[Lingual thyroid. A case report].

Account on a tongue thyroid case and bibliographic review of the subject. It is an anomaly due to the thyroid gland not come down. Symptomatic cases are scarce (around 400 reported in the literature). Diagnosis is basically scintigraphic. When there are symptoms management should begin with thyrotoxine. More severe instances require surgical exeresis.

[Metastasis from hypernephroma to the parotid gland].

Report of a carcinoma of renal clear cells, or hypernephroma, metastasized to parotid gland, in a 63 years old man. The occurrence of a mass progressively growing in link parotid was the early manifestation of the illness and the postsurgical anatomopathological study discovered the primary growth sitting in the kidney. Bibliographical survey of the subject and clinical, diagnostical and therapeutic features of this case as well.

[Incidence of nasopharyngeal cancer in La Rioja (Spain). Epidemiological aspects].

A retrospective study was made of patients with nasopharyngeal carcinoma diagnosed at the Hospital San Millán of La Rioja (Spain), between August 1989 and August 1995. Epidemiological and clinical factors, and their relation to findings from other regional studies, were examined. Most patients had stage III and IV (1986 UICC/AJCC staging system) disease, which indicates that the diagnosis tended to be late. Primary care physicians should consider this disease in cases of nasal obstruction, nosebleed, or seromucous otitis in adults.
