[Is it necessary to conduct a urodynamic study in the diagnosis of urinary incontinence?]. / Es necesario realizar estudio urodinámico en el diagnóstico de la incontinencia urinaria?

Urinary incontinence is a dysfunction that affects 20%-50% of the women in Spain, depending on age. Even though it does not involve a prognosis of severity, it reduces self-esteem, limits independence and clear deteriorates quality of life. The diagnosis is generally made following the international criteria collected in the clinical practice guidelines. Even if it is true that the symptoms make it possible to suspect the nature of the functional disorder, this is not always sufficient or conclusive and there may be errors even in the clearest cases. Even so, the need to conduct a urodynamic study in the assessment of women with urinary incontinence diagnosed according to the symptoms mentioned continues to be debatable and there are no unified and defined criteria in our setting in regards to when it is necessary to request urodynamic tests.

[Influence of the diet on the development of colorectal cancer in a population of Madrid]. / Influencia de la dieta en la aparición del cáncer colorrectal en una población de Madrid.

OBJECTIVE: Although the genetic component in colorectal carcinoma (CRC) is well established, some environmental factors, mainly dietary, can favor its development. The objective of this study is to evaluate the relationship between daily consumption of specific food groups and development of CRC. METHODS: We carried out a case-control study in an area of Madrid; 196 patients with diagnosis of CRC with confirmed histology and registered to May 1998 in the Community of Madrid tumor register were included, and they were compared with 196 controls matched by age, sex, and geographical area. All of them filled out a questionnaire with information on diet, substance abuse, physical activity, drugs, and family history of CRC. RESULTS: The logistic regression analysis showed a weakly positive association with meat (OR: 1.02; CI: 1.01-1.04), viscera (OR: 1.12; CI: 1.02-1.23), and sausage (OR: 1.07; CI: 1.03-1.1) consumption, and a modest inverse association with consumption of yogurt (OR: 0.97; CI: 0.95-0.98), tomato (OR: 0.99; CI: 0.98-0.99), strawberries and cherries (OR: 0.97; CI: 0.95-0.99), oranges, grapefruits, and natural fruit juices (OR: 0.99; CI: 0.98-1). CONCLUSIONS: These results are an additional empirical evidence that must be confirmed through prospective studies.
