A prospective study of oesophageal 24-h ambulatory pH monitoring in patients with functional dyspepsia

BACKGROUND: The diagnostic utility of 24-h oesophageal ambulatory pH monitoring in patients with functional dyspepsia has not been well established. AIMS: We performed a prospective study of oesophageal pH monitoring in patients with functional dyspepsia in order to assess whether a positive pH test might predict response to proton pump inhibitor therapy in a subset of functional dyspepsia patients. PATIENTS: Forty Helicobacter pylori-negative functional dyspepsia patients (35 males and 5 females, mean age (+/-S.E.M.) of 54+/-2.4 years) with predominantly unspecified dyspepsia subtype and normal distal oesophageal biopsies. METHODS: All subjects were randomised in a double-blind fashion to either omeprazole 20 mg/day or placebo daily for four weeks after 24-h pH monitoring. RESULTS: Twenty-four-hour pH monitoring was abnormal in 9 of the 21 patients (43%) in the omeprazole group and 5/19 (26%) of the placebo group (p=NS). Patients who reported symptomatic improvement on the Gastrointestinal Symptom Rating Scale were no more likely to have abnormal scores on pH monitoring than patients who did not have symptomatic response. CONCLUSIONS: Although approximately one-third of functional dyspepsia patients will have abnormal profiles on 24-h ambulatory oesophageal pH monitoring, an abnormal score does not appear to predict response to proton pump inhibitor therapy in patients with unspecified functional dyspepsia.

目的：以杓型高血压患者为对照，探讨非杓型高血压在左心室肥厚发生和发展中的作用。方法：应用２４小时动态血压和超声心动图检测２３０例高血压患者，选择年龄、病程、昼间血压基本相同的杓型、非杓型高血压患者１５０例，其中男性各４５例，女性各３０例。结果：非杓型高血压患者舒张末期左心房内径显著大于杓型高血压患者，男性分别为３５．８±２．９ｍｍ与３１．２±２．７ｍｍ（Ｐ＜０．０１）；女性分别为３２．４±２．５ｍｍ与２９．４±１．８ｍｍ（Ｐ＜０．０５）。女性杓型、非杓型高血压患者间舒张末期左心室内径的差异（４９．５±３．２ｍｍ与５４．８±３．７ｍｍ，Ｐ＜０．０１）比男性（５３．８±４．６ｍｍ与５７．４±４．５ｍｍ，Ｐ＜０．０５）更为显著。非杓型高血压患者左心室重量指数显著大于杓型高血压患者，男性分别为１５８．０±７．９ｇ／ｍ２与１３０．０±６．７ｇ／ｍ２（Ｐ＜０．０１）；女性分别为１３８．０±５．６ｇ／ｍ２与１１５．０±４．７ｇ／ｍ２（Ｐ＜０．０１）。结论：非杓型高血压患者左心室肥厚的检出率比杓型高血压患者为高。     

Chronotherapy of Hypertension with Angiotensin Receptor Blockers–A Meta-Analysis of Blood Pressure Measured by Ambulatory Blood Pressure Monitoring in Randomized Trials

BackgroundWe performed this meta-analysis evaluating the efficacy of chronotherapy of hypertension with angiotensin receptor blockers (ARBs).MethodsWe searched Pubmed, Web of Science, and Cochrane for all published randomized trials that compare antihypertensive effects of ARBs between bedtime dosing and awakening dosing. Blood pressure (BP) was measured by ambulatory BP monitoring in patients with mild or moderate essential hypertension.ResultsThe effects of ARBs on BP were assessed in 805 essential hypertensive patients included in 8 trials with a follow-up of 12 ± 3 weeks. The sleep-time systolic and diastolic BP (SBP, DBP) with bedtime dosing greatly decreased as compared with awakening dosing (weighted mean differences [WMD] for SBP WMD ?5.23 [95% confidence intervals (CI), ?7.27, ?3.20] mm Hg, p < 0.001; WMD for DBP ?2.94 [95% CI, ?4.52, ?1.36] mm Hg, p < 0.001). The reduction of daytime SBP (WMD 0.98 [95% CI, ?0.20, 2.17] mm Hg, p = 0.10), DBP (WMD 0.11 [95% CI, ?0.68, 0.89] mm Hg, p = 0.79), 24 hour SBP (WMD ?0.75 [95% CI, ?1.93, 0.42] mm Hg, p = 0.21) and DBP (WMD ?0. 77 [95% CI, ?1.55 0.01] mm Hg, p = 0.05) with bedtime dosing was similar with awakening dosing.ConclusionsBedtime dosing with ARBs is more effective in lowering sleep-time BP than awakening dosing in patients with essential hypertension, suggesting a utilization of chronotherapy of hypertension with ARBs to reduce sleep-time high BP. Larger multi-ethnic studies are needed to investigate the efficacy of chronotherapy of hypertension.

Blood pressure changes during the game of squash.

The extent and pattern of the blood pressure response to the playing of squash was studied in five healthy volunteers using intra-arterial blood pressure recordings. Systolic pressure increased more than diastolic, but by only 18% of basal, peaking 5.2 +/- 2.3 min into the game (mean game duration 49 +/- 4 min). Thereafter there was a progressive decline, with reducing pulse pressure towards basal. There was a marked and significant increase in beat-by-beat blood pressure variability (P less than 0.01) and systolic peaks of up to 200 mmHg were recorded. A peak heart rate of 171 +/- 25 beats min-1 occurred at 20 min. These findings do not support the concept of a disproportionate and prolonged pressor response induced by playing squash. The possibility of high single-beat systolic peaks still justifies some caution in subjects at risk of arterial rupture.     

特发性室性心动过速患者QT间期与RR间期关系的研究

为研究特发性室性心动过速（ＩＶＴ）患者日常活动中的心室复极状况，对１７例左室ＩＶＴ（ＩＬＶＴ，即ＩＬＶＴ组）、１０例右室ＩＶＴ（ＩＲＶＴ，即ＩＲＶＴ组）、１７例正常人（正常对照组）进行２４小时动态心电图检查，测量ＱＴ间期，计算其与ＲＲ间期的关系。三组间平均、最大、最小ＱＴ间期及校正ＱＴ间期均无显著性差异。ＩＲＶＴ组ＱＴ间期与ＲＲ间期直线回归方程的斜率值较正常对照组高（０．２４３±０．０４３ｖｓ０．２０１±０．０３９，Ｐ＜０．０５），ＩＬＶＴ组斜率值与正常对照组比较无显著性差异（０．１９０±０．０４３ｖｓ０．２０１±０．０３９，Ｐ＞０．０５）。尽管ＩＲＶＴ的患者经检查心脏未见明显器质性病变，但存在心室复极的心率适应性异常的改变，此可能是该类患者心肌电不稳定的原因之一

Loop Ileostomy Closure at an Ambulatory Surgery Facility

INTRODUCTION: Temporary loop ileostomies have become widely used in colorectal surgery. Subsequent ileostomy closure has traditionally required hospital admission with observation until return of bowel function. On the basis of clinical observation, the authors hypothesized that loop ileostomy closure may be performed safely without prolonged in-hospital observation. METHODS: A protocol for 23-hour observation after loop ileostomy closure was implemented at a single institution and applied to 28 patients at an ambulatory surgery facility. Patient outcomes were reviewed and results compared with a cohort of 30 patients undergoing loop ileostomy closure before introduction of the protocol. RESULTS: The study and control groups were statistically similar in age, gender, diseases, and duration after original operation. Twenty-eight patients underwent loop ileostomy closure, and all were discharged the following day. Two patients were admitted for nausea and vomiting within 48 hours after closure and remained in the hospital for two and four days, respectively. One of these patients was readmitted 12 days after surgery with an abdominal abscess that was drained percutaneously. The mean cost per patient in the study group was $2,665. For the control population, the mean hospital stay was 2.9 days. Return of bowel function was delayed in two patients, resulting in prolonged hospital stays of six and eight days, respectively. Two patients were readmitted after discharge for nausea and vomiting. The mean cost per cohort patient was $3,811. CONCLUSIONS: Patients undergoing loop ileostomy closure may be discharged safely after overnight observation without increased complications or hospital readmissions. This practice significantly reduces the use of hospital resources and decreases economic cost without compromising care.     

儿童口腔门诊全身麻醉操作指南

近年来,在全身麻醉状态下完成门诊儿童口腔诊疗,已逐渐发展成为一种较成熟的行为管理模式。由于门诊儿童口腔诊治时间短、流动性大、周转快,对麻醉及诊疗期的管理提出更高要求。中华口腔医学会镇静镇痛专业委员会组织专家,制定儿童口腔门诊全身麻醉操作指南,从口腔门诊实施全身麻醉的范围、临床基本条件、口腔诊疗种类、诊治前评估与准备、麻醉实施与监测、恢复和苏醒期管理、常见并发症及处理要点等方面给出具有可操作性的实施规范,对促进我国儿童门诊全身麻醉下口腔诊疗安全性和舒适化的快速发展具有重要意义。
