Nocturia is a common symptom associated with benign prostatic hyperplasia which can persist even after effective treatment of BPH. Other causes may be responsible. We investigated a group of patients who were treated for BPH and continue to have nocturia. Our study has found a high prevalence (85.4%) of nocturnal polyuria in this group of patients. It has important clinical implication since the condition can be effectively treated with oral desmopressin. Empirical treatment without a routine frequency volume chart may be appropriate due to its high prevalence. 相似文献

Background The nocturnal nondipping and elevated morning blood pressure (BP) in patients with obstructive sleep apnea syndrome (OSAS) have not yet been well investigated in Chinese patients. This study aimed to describe the BP profile, and to elucidate the relationships between daytime BP and nighttime BP, and between evening BP and morning BP in patients with OSAS.
Methods Twenty teaching hospital sleep centers in China were organized by the Chinese Medical Association to participate in this study and 2297 patients were recruited between January 2004 and April 2006. BP assessments were made at four time points (daytime, evening, nighttime and morning) and polysomnography (PSG) was performed and subjects were classified into four groups by their apneahypopnea index (AHI): control, n=213 with AHI <5; mild, n=420 with AHI ≥5 and <15; moderate, n=460 with AHI ≥15 and <30; and severe, n=1204 with AHI ≥30. SPSS 11.5 software package was used for statistical analysis and figure drawing.
Results All the average daytime, nighttime, evening and morning BPs were positively correlated with AHI and negatively correlated with nadir nocturnal oxygen saturation. The ratios of nighttime/daytime and morning/evening average BP were positively correlated with AHI. The ratio of nighttime/daytime systolic BP became a “reversed BP dipping” pattern until the classification reached severe, while the ratio of nighttime/daytime diastolic BP became reversed at moderate. Similarly, the ratio of morning/evening diastolic BP becomes reversed even at mild.
Conclusions OSAS may result in higher BP levels at all four time points. The ratios of nighttime/daytime and morning/evening BP increase with increased AHI. The increasing of diastolic BP, which is inclined to rise more quickly, is not parallel with increasing systolic BP.

We determined the pressor effect of phenylpropanolamine hydrochloride, a widely used sympathomimetic agent, in 14 patients with autonomic failure and orthostatic hypotension. Blood pressure was monitored every five minutes in the sitting position with an automated device. Oral administration of 25 mg of phenylpropanolamine hydrochloride in nine patients produced significant increases in systolic (32 mm Hg), diastolic (15 mm Hg), and mean (21 mm Hg) blood pressures. The pressor effect appeared within the first 60 minutes and was still present at 105 minutes. There was no change in heart rate. Blood pressure was also significantly raised by administration of 12.5 mg of oral phenylpropanolamine hydrochloride in five additional patients. We conclude that administration of 25 mg of phenylpropanolamine hydrochloride elicits a potent pressor response in patients with orthostatic hypotension and that significant hypertension may result. 相似文献

INTRODUCTION
Weight management programmes (WMPs) can help overweight individuals lose weight, and thus prevent complications associated with obesity. Herein, we describe the demographic profile, clinical characteristics, motivations and expectations, and outcomes of patients enrolled in a nonsurgical WMP.METHODS
This was a retrospective study of consecutive patients with a body mass index (BMI) of > 23 kg/m2 enrolled in the four-month WMP at the Health For Life Clinic, Alexandra Hospital, Singapore, between 1 and 31 August 2009. Demographic data, medical history and source of referral were recorded. Details on personal motivations and weight loss goals were obtained from the completed self-administered questionnaires of the WMP participants. Weight, waist circumference, fat percentage and BMI were measured at the start and end of the WMP. A weight loss of ≥ 5% was deemed as a successful outcome.RESULTS
A total of 58 patients (mean age 37.2 years) were included in our study. Of these 58 patients, 58.6% were of Chinese ethnicity and 55.2% were male. Many patients (32.8%) attributed their weight gain to work- or study-related stress, and a minority to poor eating habits (12.1%) or a lack of exercise (10.3%). Patients’ motivations included a desire for better health (53.4%) and better fitness (15.5%). However, only 53.4% patients scored their motivation as high (i.e. a score of > 7). The mean expected weight loss was 9.9 kg at 4 months, and 14.1 kg at 12 months. Among the 40 patients (69.0%) who completed the programme, the mean percentage weight loss was 1.8 ± 4.3%. A weight loss of ≥ 5% was achieved by 8 (13.8%) patients.CONCLUSION
Although the patients in our study cohort were young and educated, only a portion of them appeared to be highly motivated to lose weight, despite joining the WMP. There is a need for patients to be guided on how to set realistic weight loss goals. 相似文献18.

目的按照高血压时间治疗学中的择时给药,探讨不同的给药时间对老年高血压患者血压晨峰的影响。方法采用180-EA动态血压监测系统动态血压监测法筛选出206例有血压晨峰的老年高血压患者,随机分为A组采取常规的上午8时给药;B组采取晚上睡前给药,共治疗4周。治疗前后均进行动态血压监测的检查。结果治疗前两组的24h平均血压、白天平均血压、夜间平均血压以及血压晨峰均元统计学差异(P〉0.05);治疗后两组的24h平均血压、白天平均血压、夜间平均血压以及血压晨峰均明显下降,与治疗前比较有统计学差异(P〈0.01);治疗后B组的夜间血压及血压晨峰下降明显,且能恢复昼夜节律与治疗后的A组比较有统计学差异(P〈0.01)。结论对明显有血压晨峰的老年高血压患者,采取时间治疗可以更好的纠正夜间高负荷血压、抑制血压晨峰、恢复血压昼夜节律。 相似文献
