Hechos históricos en pacientes con disfunción del piso pelviano / History of patients with pelvic floor dysfunction

OBJECTIVES: 1) To determine differences between sexes; 2) To determine differences by sex and age groups in symptom onset, time of evolution, clinical forms and probable associated causes. POPULATION AND SAMPLE: 83 consecutive patients with diagnosed PCP (X age = 50.9 SE 2.21). 25 males (30.1% x 51.2 years-old, SE 4.1) and 58 females (69.9%, X 50.8 years-old, SE 2.2). Patients with organic colon-rectum pathology (with the exception of hemorrhoidal pathology, proctologic surgery and active anus fissure) had been excluded. METHODS: ...

Random walk with an exponentially varying step

A random walk with exponentially varying step, modeling damped or amplified diffusion, is studied. Each step is equal to the previous one multiplied by a step factor s (01/s relating different processes. For s<1/2 and s>2, the process is retrodictive (i.e., every final position can be reached by a unique path) and the set of all possible final points after infinite steps is fractal. For step factors in the interval [1/2,2], some cases result in smooth density distributions, other cases present overlapping self-similarity and there are values of the step factor for which the distribution is singular without a density function.

[Massive pleural effusion in liver cirrhosis without ascites]. / Derrame pleural masivo en cirrosis hepática sin ascitis.

We present two patients with masive pleural effusion, asociated to cirrhosis. There was no clinical evidence of ascites, and in the first case it didn't even show up in the CT scanning. Al other posible causes were discarded and the therapeutic response was analysed. We evaluated the pathophysiologic mechanisms of the syndrome and we suggest the pneumoperitoneum as a diagnostic procedure which is easy to apply and carries low costs.

Derrame pleural masivo en cirrosis hepática sin ascitis / Massive pelural effusion in liver cirrhosis without ascites

Se presentan dos pacientes con derrame pleural masivo asociado a cirrosis, sin evidencias clínicas de ascitis, y en el primero de los casos sin ascitis visible en la T.A.C. Se descartan otras patologías causales y se analiza su respuesta terapéutica. Se analizan los mecanismos de producción del síndrome y se postula al Neumoperitoneo como rpocedimiento diagnóstico fácil y de bajo costo.
