[Epidemiology of pseudotumor cerebri]. / Epidemiología del pseudotumor cerebral.

OBJECTIVE: To determine the epidemiology of pseudotumor cerebri (PTC) as seen in patients attending our ophthalmology department. METHODS: The medical records of patients diagnosed with PTC in our hospital during a ten-year period (1994 to 2004) were obtained, with only those patients with PTC diagnosed in our ophthalmology department being considered. The following data were reviewed: sex, age at diagnosis, body mass index (BMI), opening cerebrospinal fluid (CSF) pressure, and the results of CT and MRI. RESULTS: Twenty-nine patients were diagnosed with PTC during this time period. Twenty-six were females (89.6%) and 3 were males (10.4%). The calculated incidence of PTC in our population was 3.2 per 100.000 persons and 5.1 per 100.000 persons in the general population that attend our hospital. CONCLUSION: The incidence of PTC was higher than that previously reported.

Epidemiología del pseudotumor cerebral / Epidemiology of pseudotumor cerebri

Objetivo: Determinar la epidemiología del pseudotumor cerebral (PTC) en los pacientes de nuestro servicio de oftalmología. Métodos: Se revisaron las historias clínicas de todos los pacientes diagnosticados de PTC en el hospital entre los años 1994 y 2004, considerándose para el estudio los PTC diagnosticados por el servicio de oftalmología. Se recogieron los datos del sexo, edad al diagnóstico, índice masa corporal (IMC), presión de salida del líquido cefalorraquídeo (LCR), y los resultados de la TAC y RMN. Resultados: Veintinueve pacientes fueron diagnosticados de PTC entre 1994 y 2004. El 89,6% (26) de los pacientes fueron mujeres y el 10,4% (3) fueron varones. La incidencia de PTC en nuestra población oftalmológica fue de 3,2 por 100.000 y de 5,1 por 100000 si se considera la población general dependiente de nuestro hospital. Conclusión: La incidencia de PTC encontrada fue mayor que la publicada previamente

[Bardet-Biedl syndrome: subclinical renal disorders in 2 siblings]. / Síndrome de Bardet-Biedl: alteraciones renales subclínicas en dos hermanos.

Two siblings with Bardet-Biedl's syndrome are studied, in whom renal structural and functional disorders were observed, with reduction in the ability to concentrate urine in both cases and decrease of creatinine clearance in the second case. The study of the hypophyseal function was normal.

Skeletal muscle changes in chronic alcoholic patients. A conventional, histochemical, ultrastructural and morphometric study.

Muscle biopsies of 20 alcoholic patients (15 males and 5 females), most of whom had liver disease and with no clinical or analytical evidence of neuromyopathy, were studied. 10 abstemious patients with no neuromuscular disease were selected as controls. Conventional histology failed to show significant skeletal muscle changes. A characteristic histochemical picture of tubular aggregates was found in one patient. An enlargement of the intermyofibrillar space with increase in glycogen deposition and fat droplets were detected ultrastructurally while 2 of the patients showed tubular aggregates. The mitochondriae of the alcoholic patients had a smaller perimeter and area than those of the control group (P less than 0.004 and P less than 0.008, respectively). These results suggest that the prolonged ingestion of alcohol can cause a mitochondrial alteration only evidenced by morphometry, with poor clinical, biochemical, electrophysiological and histological expression of myopathy. These findings can represent an early stage of alcoholic skeletal muscle injury.

[Recurrent thrombophlebitis and bilateral gynecomastia. Primary manifestations of hepatocarcinoma]. / Thrombophlébite récidivante et gynécomastie bilatérale. Manifestation primitive d'un hépatocarcinome.

Thirty-three-year-old male patient, without recognized risk factors, presenting with recurrent thrombophlebitis and bilateral gynecomastia as the only sign of feminization. Twenty-seven months after onset hepatocarcinoma of the right lobe was diagnosed. The rest of the liver was normal. Gynecomastia resolved after surgical removal of the tumor. Thromboembolism did not recur.
