RESUMEN
AIM: Forced expiratory volume in 1 second (FEV1) is a reliable and easily measured lung function index, which is nowadays used for early detection of chronic obstructive pulmonary disease. It has also been established recently as an important predictor of all-cause, cardiovascular and cerebrovascular morbidity and mortality in the Western World. Similar implications have been made with regard to peak expiratory flow rate (PEFR). The present study was designed in order to compare the FEV1 and PEFR values of non-professional, smoking and non-smoking male athletes to those predicted for the general, non-athlete population. METHODS: A total of 141 non-professional tennis players aged 30-74 years were studied (99 smokers and 42 non-smokers). FEV1 and PEFR of all men were measured by means of a one flow spirometer, and compared to those predicted for their age and height, based on formulas for the non-athlete, healthy, non-smoking population. RESULTS: Non-professional tennis players had significantly higher FEV1 and PEFR values, compared to FEV1 and PEFR predicted, respectively. No statistically significant difference was observed between smokers and non-smokers. CONCLUSIONS: Our study confirms that even moderate physical activity, such as non-professional tennis, can improve FEV1 and PEFR values, maintaining a normal respiratory function, which is a strong predictor of reduced cardiovascular and overall morbidity and mortality. FEV1 and PEFR are easy to measure parameters that should be used more often for the assessment of general health status.

OBJECTIVE: To develop of an isoperistaltic invaginated valve for the treatment of short bowel syndrome. DESIGN: Randomised experimental study SETTING: University Hospital, Greece MATERIAL: 8 mongrel dogs INTERVENTION: 90% resection of the small bowel, followed by construction of an invaginated valve one month later. MAIN OUTCOME MEASURES: weight loss, fat excretion in the faeces, radiographic and histological examination of the valve, pressure curve along the valve. RESULTS: Weight loss and steatorrhoea were reversed over a period of 2-3 months without evidence of intestinal obstruction in any of the animals. CONCLUSIONS: The construction of an isoperistaltic invaginated valve could be a solution to the management of the short gut syndrome.

In 10 mongrel dogs, massive resection of small intestine was performed by removing 90% of its length. Following a period of approximately 2 months, the animals presented excessive steatorrhea and severe cachexia. Construction of a valve using a local transposition flap within the intestinal lumen near the colon resulted in a detainment of weight loss and steatorrhea. The animals were kept under observation over a period of 4 months.
