Is Caffeine Intake Associated With Urinary Incontinence in Japanese Adults?

Objectives: To investigate whether caffeine intake is associated with urinary incontinence (UI) among Japanese adults. Methods: A total of 683 men and 298 women aged 40 to 75 years were recruited from the community in middle and southern Japan. A validated food frequency questionnaire was administered face-to-face to obtain information on dietary intake and habitual beverage consumption. Urinary incontinence status was ascertained using the International Consultation on Incontinence Questionnaire-Short Form. Results: Mean daily caffeine intake was found to be similar between incontinent subjects (men 120 mg, women 94 mg) and others without the condition (men 106 mg, women 103 mg), p=0.33 for men and p=0.44 for women. The slight increases in risk of UI at the highest level of caffeine intake were not significant after adjusting for confounding factors. The adjusted odds ratios (95% confidence interval) were 1.36 (0.65 to 2.88) and 1.12 (0.57 to 2.22) for men and women, respectively. Conclusions: No association was evident between caffeine intake and UI in middle-aged and older Japanese adults. Further studies are required to confirm the effect of caffeine in the prevention of UI

Discrepancies in Perception of Urinary Incontinence between Patient and Physician after Robotic Radical Prostatectomy

PURPOSE: Reported incidence of urinary incontinence after a radical prostatectomy (RP) varies between studies. This may be due not only to the definition of incontinence applied, but also how the information is acquired. We investigated the differences in perception of post robot-assisted laparoscopic RP (RALP) urinary incontinence acquired through doctor interviews and patient-reported questionnaires. MATERIALS AND METHODS: Of 238 consecutive men who underwent RALP by a single surgeon between July 2005 and February 2008, we evaluated 66 men using the International Consultation on Incontinence Questionnaire (ICIQ) at various time points after surgery. Each patient's ICIQ results were considered to be the patient's perceptions of urinary incontinence. The physician at the same time directly interviewed the patients about the number of pads used and considered complete continence to be equivalent to the use of no pads or safety liners. RESULTS: Of the 66 patients, the physician reported that 34 (51.5%) had obtained complete continence. However, analysis of the questionnaires of these 34 patients revealed that only 5 (14.7%) patients reported that they never leaked during the past 4 weeks. Most patients (11 patients, 32.4%) who did not use any pad did in fact reported leakage of a small or moderate amount of urine about once a day. CONCLUSION: Our results indicate that there are discrepancies in the perception of urinary incontinence between doctor and patient after RALP. Nonuse of pads is not equivalent to obtaining complete urinary continence. Therefore, the number of pads used is not a good measure to determine the status of complete urinary continence.ope

Breathlessness is associated with urinary incontinence in men: A community-based study

<p>Abstract</p> <p>Background</p> <p>Urinary incontinence (UI) is a distressing problem for older people. To investigate the relationship between UI and respiratory symptoms among middle-aged and older men, a community-based study was conducted in Japan.</p> <p>Methods</p> <p>A convenience sample of 668 community-dwelling men aged 40 years or above was recruited from middle and southern Japan. The International Consultation on Incontinence Questionnaire-Short Form, the Medical Research Council's dyspnoea scale and the Australian Lung Foundation's Feeling Short of Breath scale, were administered by face-to-face interviews to ascertain their UI status and respiratory symptoms.</p> <p>Results</p> <p>The overall prevalence of UI was 7.6%, with urge-type leakage (59%) being most common among the 51 incontinent men. The presence of respiratory symptoms was significantly higher among incontinent men than those without the condition, especially for breathlessness (45% versus 30%, <it>p </it>= 0.025). The odds of UI for breathlessness was 2.11 (95% confidence interval 1.10-4.06) after accounting for age, body mass index, smoking and alcohol drinking status of each individual.</p> <p>Conclusions</p> <p>The findings suggested a significant association between UI and breathlessness in middle-aged and older men.</p

The diagnostic strength of the 24-h pad test for self-reported symptoms of urinary incontinence in pregnancy and after childbirth

The clinical impact of incontinence in pregnancy and after childbirth is growing because some studies report the efficacy of physiotherapy in pregnancy and because obstetric choices are supposed to have significant impact on post-reproductive urinary function (Goldberg et al. in Am J Obstet Gynecol 188:1447–1450, 2003). Thus, the need for objective measurement of urinary incontinence in pregnancy is growing. Data on pad testing in pregnancy are lacking. We assessed the clinical relevance of the 24-h pad test during pregnancy and after childbirth, compared with data on self-reported symptoms of urinary incontinence and visual analogue score. According to the receiver operating characteristic curve, the diagnostic value of pad testing for measuring (severity of) self-reported incontinence during pregnancy is not of clinical relevance. However, for the purposes of research, pad tests, combined with subjective/qualitative considerations, play a critical role in allowing comparisons across studies, quantifying the amount of urine loss and establishing a measure of severity

18F-fluoro-deoxy-glucose focal uptake in very small pulmonary nodules: fact or artifact? Case reports

ABSTRACT: BACKGROUND: F-fluoro-deoxy-glucose (18F-FDG) positron emission tomography integrated/combined with computed tomography (PET-CT) provides the best diagnostic results in the metabolic characterization of undetermined solid pulmonary nodules. The diagnostic performance of 18F-FDG is similar for nodules measuring at least 1 cm and for larger masses, but few data exist for nodules smaller than 1 cm. CASE PRESENTATION: We report five cases of oncologic patients showing focal lung 18F-FDG uptake on PET-CT in nodules smaller than 1 cm. We also discuss the most common causes of 18F-FDG false-positive and false-negative results in the pulmonary parenchyma. In patient 1, contrast-enhanced CT performed 10 days before PET-CT did not show any abnormality in the site of uptake; in patient 2, high-resolution CT performed 1 month after PET showed a bronchiole filled with dense material interpreted as a mucoid impaction; in patient 3, contrast-enhanced CT performed 15 days before PET-CT did not identify any nodules; in patients 4 and 5, contrast-enhanced CT revealed a nodule smaller than 1 cm which could not be characterized. The 18F-FDG uptake at follow-up confirmed the malignant nature of pulmonary nodules smaller than 1 cm which were undetectable, misinterpreted, not recognized or undetermined at contrast-enhanced CT. CONCLUSION: In all five oncologic patients, 18F-FDG was able to metabolically characterize as malignant those nodules smaller than 1 cm, underlining that: 18F-FDG uptake is not only a function of tumor size but it is strongly related to the tumor biology; functional alterations may precede morphologic abnormalities. In the oncologic population, especially in higher-risk patients, PET can be performed even when the nodules are smaller than 1 cm, because it might give an earlier characterization and, sometimes, could guide in the identification of alterations missed on CT
