ABSTRACT

El cáncer de pulmón es una enfermedad epidé-mica que comienza en el siglo XX y continúa hastanuestros días y por incidencia es el primer tipo decáncer en varones y el tercero en mujeres. La causafundamental de carcinoma broncogénico en los paí-ses desarrollados es el hábito de fumar tabaco, que semantiene especialmente entre las mujeres jóvenes. Algunas series de casos han mostrado un aumento de laincidencia de cáncer de pulmón en mujeres siguiendola tendencia descrita en las series americanas. Este trabajo valora a partir de nuestros datos las expectativaspara el futuro de esta enfermedad. En nuestro medio ha disminuido la incidencia bruta de cáncer de pulmón en hombres (desde 43 hasta27/100.000 habitantes) y ha aumentado en mujeres(desde 2,7 hasta 4,1/100.000) con un descenso en elúltimo año. Sin embargo las perspectivas epidemiológicas de otros países y otras series de casos sugieren que el aumento será espectacular en los próximosaños (AU)

ABSTRACT

OBJETIVO: Estudiar la posible relación entre las manifestaciones clínicas de la sarcoidosis y los polimorfismos del gen de laciclooxigenasa-2 (COX-2).MÉTODO: Estudio multicéntrico observacional transversal en el que participaron 7 hospitales de España. Se incluyeron pacientes diagnosticados de sarcoidosis según criterios internacionales. De cada caso se recogió edad, sexo, método diagnóstico, enzima convertidora de angiotensina, pruebas de función respiratoria, estadio radiológico y clínica del paciente en el momento del diagnóstico. Los hallazgos clínicos se agruparon en respiratorios y sistémicos. Los estudios genéticos se realizaron a partir del ADN obtenido de linfocitos de sangre periférica. El ADN se amplificó mediante PCR convencional y los polimorfismos fueron analizados por sondas de hibridación fluorescentes y curvas de disociación. Se determinaron4 variantes alélicas del gen de la COX-2: COX2.5909T>G,COX2.8473T>C, COX2.926G>C y COX2.3050G>C. RESULTADOS: La muestra se compuso de 131 casos de sarcoidosis (63 hombres; edad: 47 ± 15 años), todos con diagnóstico histológico menos 5 casos. El polimorfismo COX2.3050G>C en homocigosis resultó estar significativamente presente entre los pacientes con manifestaciones sistémicas frente al resto de pacientes (4,6% vs 0%;p=0,045). La presencia de manifestaciones sistémicas de la enfermedad estuvo significativamente asociada a los pacientes portadores del alelo C de dicho polimorfismo (34,4% vs. 18,6%; p=0,031; OR:2,3; IC 95%: 1,03-5,12). El resto de polimorfismos estudiados no estuvieron relacionados con la expresión clínica de la enfermedad. CONCLUSIÓN: La presencia de manifestaciones sistémicas parece estar relacionada con los portadores del alelo C del polimorfismoCOX2.3050G>C de la COX-2 (AU)


OBJECTIVE: To study clinical manifestations of sarcoidosis according to cyclooxigenase-2 (COX-2) polymorphisms. METHOD: Observational cross-sectional multicentre trial in which 7 Spanish hospitals participated. Patients diagnosed withs arcoidosis according to international criteria were included. Age, gender, diagnostic method, angiontens in converting enzyme, pulmonary function tests, radiological stage and clinical findings at the moment of the diagnosis were recorded for each case included. Clinical findings were grouped as respiratory or systemic. Genetic studies were performed on DNA extracted from peripheral blood lymphocytes. DNA was amplified by conventional PCR and polymorphisms were studied by Fluorescent Hybridization Probe-Melting Curves. COX-2 polymorphisms genotyped were COX2.5909T>G, COX2.8473 T>C, COX2.926 G>C y COX2.3050 G>C.RESULTS: 131 sarcoidosis patients (63 males, age: 47 ± 15years) were included. All included patients had a histological diagnosis except for 5 patients. COX2.3050G>C homozygote polymorphism resulted to be significantly present in patients with a systemic manifestation of the disease as compared with the rest of the sample(4,6% vs 0%; p = 0,045). Systemic manifestations were significantly associated with allele C carriers of this polymorphism (34.4% vs.18.6%; p = 0.031; OR: 2.3; IC 95%: 1.03 – 5.12). The rest of the studied polymorphisms were not significantly related to the clinical manifestations of the disease. CONCLUSION: Our results suggest that allele C carriers ofCOX2.3050G>C polymorphism are associated with the systemic manifestations of sarcoidosis (AU)

ABSTRACT

Tumours of the middle ear are rare. Among them glomus tympanicum is the most frequent, followed by adenoma of the middle ear (AME). This insidious pathology entity displays unspecific clinical and audiological features. Advances in histology and immunohistochemistry have greatly contributed to an accurate diagnosis. We report our experience with two patients, a middle-aged man and a woman, diagnosed in our hospital. Both patients underwent surgical treatment and have shown no signs of recurrence after a 27- and 28-month follow-up. In both cases an accurate diagnosis was confirmed by histological and immunohistochemical analysis.

ABSTRACT

Los tumores del oído medio son poco habituales, siendo el de mayor frecuencia el glomus timpánico seguido en mucha menor frecuencia por el adenoma de oído medio (AOM). Es una entidad que se presenta de forma insidiosa, con unos hallazgos clínicos y audiológicos muy inespecíficos, a cuyo diagnóstico de certeza han contribuido de forma importante los avances en histología e inmunohistoquímica. Presentamos dos casos diagnosticados recientemente en nuestro centro, en un hombre y una mujer ambos de mediana edad. Los dos pacientes fueron tratados mediante cirugía y permanecen sin signos de recidiva después de 27 y 28 meses de seguimiento. En ambos casos se llegó al diagnóstico definitivo mediante el análisis histológico e inmunohistoquímico

ABSTRACT

The aim of this study is to evaluate the erythrocyte morphology (area, perimeter, shape) and its correlation with high alcohol intake and the conventional blood test (MCV, GOT/GPT, and activated PTT). 60 persons were studied (20 non-drinkers, 20 chronic alcoholics and 20 with hepatic cirrhosis). The erythrocyte area and perimeter was significantly higher, in patients other than the group of non-drinkers. This is directly related to the alcohol intake and liver damage. We believe, that the study of the morphology of the erythrocyte is of interest as a "biological marker" related to the grade of alcoholism.
