[Chest X-ray interpretation on patients admitted in a short-stay unit. Relation with the mean length of stay]. / Interpretación de la radiografía de tórax en los pacientes que ingresan en una unidad de estancia corta. Relación con la estancia media.

INTRODUCTION: To assess the agreement between physicians of the emergency department and a radiologist in the interpretation of chest roentgenograms in patients admitted to the short-stay unit, and to determine the effect of concordance on the mean length of stay. MATERIAL AND METHOD: The medical records of patients admitted to the short-stay unit over a 4-month period were reviewed. The interpretation of the chest X-ray film made by the physician in charge of the patient at the emergency department with that made by the radiologist was compared. The mean length of stay was determined and it was analyzed if the reading of the radiograph made by the radiologist before admission would decrease the length of stay. RESULTS: A total of 260 medical records were reviewed. The overall degree of agreement was 74.2% but it was greater when the physician at the emergency department was a staff physician or a resident in the final period of training than a resident in the initial period of training (82% vs 66.4%, p < 0.003). There were no statistically significant differences regarding the day hours at which readings were made. A change in the diagnosis and/or treatment of the patient would had occurred in only 9 cases (3.5%). There were no changes in the mean length of stay according to the presence or absence of concordance, although there was a trend towards an increase in the length of stay for those cases in which diagnosis and/or treatment would had been different. CONCLUSIONS: Readings of chest roentgenograms by a radiologist before admission to a short-stay unit does not appear to be justified for all patients, although it may be justified when a staff physician or a resident in the final period of training have doubts regarding interpretation of the radiographic images. A better supervision of residents in the initial period of training may contribute to improve the diagnostic reliability of chest X-ray films.

[Fever and abdominal pain. A case of familial mediterranean fever]. / Fiebre y dolor abdominal. Un caso de fiebre mediterránea familiar.

Familial mediterranean fever (FMF) is an hereditary disease transmitted in an autosomal recessive way and characterized by recurrent and brief episodes of fever and pain secondary to serositis. The pain is usually located in abdomen simulating an acute abdomen, and in thorax in the form of pleuritic pain. The most severe complication of the FMF is the development of amyloidosis being the main cause of death. This illness affects an specific ethnic group of the mediterranean area, but the prevalence in our area is low. We present the case of a 30 years old man with recurrent thoracic and abdominal pain, whose final diagnostic was FMF. Insisting on the difficulty that it was recognize this proper illness.
