Clinical and epidemiological study of vertigo at an outpatient clinic.

Objectives: The main goal of this study was to set up a database of vertigo patients that could serve as a reference for other ENT services treating these pathologies. We present a clinical and epidemiological study of vertigo in an ENT outpatient clinic in 2001 and describe our diagnosis protocol.

Material And Methods: This was a prospective study of 591 patients (18% of the total number of 3283 first visits) controlled and treated at the ENT service of the Hospital Clinic in Barcelona.

[Cutaneous leishmaniasis: report of a case].

We present one cutaneous leishmania case that begun with cervical adenopathy without evident focus. We revise its diagnosis and treatment.

[Jugular vein thrombosis: report of six cases].

Venous thrombosis in superior extremities and neck represent less than 5% of the total of venous thrombosis. Internal jugular vein thrombosis is associated with intravenous drug abuse, long term venous catheterization, local infection or spontaneous occlusion. The clinical findings are cervical swelling, progressive inflammatory signs overlying sternomastoid muscle, and an important functional limitation.

Glutathione and glutathione S-transferases in human squamous cell carcinomas of the larynx and GSTM1 dependent risk.

Background: The aim of the present study was to establish the risk of squamous cell carcinoma (SCC) of the larynx associated with the congenital absence of glutathione S-transferase M1 (GSTM1), and to describe the expression of the isoenzymes GSTA1/2, GSTP1-1, and GSTM1 and glutathione (GSH) content in healthy and tumoral larynx tissue.

Material And Methods: Blood samples from 160 SCC male patients and 158 controls were phenotyped for GSTM1 by ELISA. Using 37 paired samples (normal and tumour specimens) from cancer patients we carried out a descriptive study of enzyme activity by ELISA (GSTs) and Ellman's as say (GSH) RESULTS: GSTM1 null phenotype was more common in the SCC group than in controls (OR 1.

Follow-up study in head and neck cancer: cure rate according to tumor location and stage.

The purpose of this clinical study was to analyze a long-term follow-up of all the patients with head and neck cancer in our institution.
