Unexpected Return for Follow-up During the First Year of Multidisciplinary Care May Be Predictive of Rapid Deterioration of Renal Function

Multidisciplinary predialysis education and team care (MDC) may slow the decline in renal function in patients with chronic kidney disease (CKD). However, associations between unexpected return during MDC and progression of renal dysfunction have not been characterized in patients with CKD. Our study aimed to determine the association between exacerbation of renal dysfunction and the frequency of unexpected return during follow-up.A total of 437 patients with CKD receiving multidisciplinary care between January 2009 and June 2013 at the Shin-Kong Wu Ho-Su Memorial Hospital were included in this retrospective observational cohort study, and multiple imputations were performed for missing data. The predictor was the frequency of unexpected return for follow-up during the first year after entering MDC. Main outcome was monthly declines in estimated glomerular filtration rates (eGFR). Moreover, the demographic data, comorbidities, history of medication, and routine laboratory data for patients with CKD were collected.Among all patients, 59.7% were male, the mean age at initiation of MDC was 69.4 ± 13.2 years, and the duration of follow-up was 21.4 ± 3.3 months. The subjects were divided into 2 groups according to frequencies of follow-up (≤4 and > 4 visits) during the 1st year of MDC. The patients with CKD were regularly followed up every 3 months as a part of MDC in our hospital, and patients who returned for more than 4 follow-up visits were included in the unexpected return group. In crude regression analyses, unexpected return was significantly associated with higher monthly declines of eGFR (β = 0.092, 95% confidence interval, 0.014–0.170). This association remained after adjustments for multiple variables, and subgroup analyses of unexpected return showed that male gender, older age, CKD stage 1 to 3, hypertension, history of coronary artery disease, and use of renin–angiotensin system blockade were significantly associated with declines in renal function.In conclusion, unexpected return for follow-up during the 1st year of MDC was significantly associated with the deterioration of renal function.

Congenital Heart Disease in Adolescents With Gluteal Muscle Contracture

Gluteal muscle contracture (GMC), presented with hip abduction and external rotation when crouching, is common in several ethnicities, particularly in Chinese. It remains unclear that the reasons why these children are weak and have no choice to accept repeated intramuscular injection. Here, we found some unique cases which may be useful to explain this question.We describe a series of special GMC patients, who are accompanied with congenital heart disease (CHD). These cases were first observed in preoperative examinations of a patient with atrial septal defect (ASD), which was proved by chest X-ray and cardiac ultrasound. From then on, we gradually identified additional 3 GMC patients with CHD. The original patient with ASD was sent to cardiosurgery department to repair atrial septal first and received arthroscopic surgery later. While the other 3 were cured postoperative of ventricular septal defect (VSD), tetralogy of fallot (TOF), patent ductus arteriosus (PDA), respectively, and had surgery directly.The study gives us 3 proposals: (1) as to CHD children, it is essential to decrease the use of intramuscular injection, (2) paying more attention to cardiac examination especially cardiac ultrasound in perioperative period, and (3) taking 3D-CT to reconstruct gluteal muscles for observing contracture bands clearly in preoperation. However, more larger series of patients are called for to confirm these findings.     

131Ⅰ治疗非Graves'甲状腺功能亢进及非毒性甲状腺肿后诱发Graves'病

~(131)I治疗非Graves’甲亢及非毒性甲状腺肿后数月,少部分患者体内出现促甲状腺激素受体抗体并诱发Graves’病(GD),发病率在0．05%～5%之间。其发病机制假说有通过自身免疫反应介导等。通过监测体内甲状腺自身抗体水平变化、甲状腺显像,可以预测~(131)I治疗后GD的发生。其治疗方法有抗甲状腺药物治疗、再次放射性~(131)I治疗、手术治疗。     

痛经的临床因素分析

目的:痛经的发病率逐年增高,重新分析痛经患者的临床因素,提出新的认识。方法:将1 158例痛经患者的临床资料及超声检查结果进行统计学分析。结果:人工流产史与痛经的发生有密切相关性(P<0.001)。结论:人工流产手术是引起痛经的主要原因。该手术所产生的副作用可对女性生理健康造成严重伤害,必须引起全社会的高度关注。     

老年单纯收缩期高血压患者脉压增大的机制、意义和治疗进展

流行病学调查表明,老年人高血压患者中50%以上表现为单纯收缩期高血压(ISH)和脉压(PP)增大.收缩压(SBP)升高及PP增大与心血管疾病(CVD)之间存在独立而显著的相关性,是CVD独立的预测因子.随着对血管病变的深入了解,认识到动脉增厚变硬、弹性减退是ISH患者主要的发病机制,这种结构及功能病变与CVD的发生有关.合理的研究治疗目标应该在控制血压的同时改善或逆转血管病变,从而进一步减少心脑血管并发症.

No impact of repeated endoscopic screens on gastric cancer mortality in a prospectively followed Chinese population at high risk.

BACKGROUND: Gastric cancer (GC) is the leading cause of cancer deaths in China. Our study prospectively evaluated the impact of repeated endoscopic screens on GC mortality in a high-risk population in China. METHODS: Between 1989 and 1999, a population-based gastroscopic screening was conducted in 4,394 residents of Linqu County, China, a region with the highest rates of GC worldwide. Residents ages 35 to 64 years received initial gastroscopies with biopsies in 1989. Repeated endoscopies were performed in 1994 and 1999. Cancer occurrences and deaths were actively monitored throughout the entire period until July 2000. Mortality from GC was compared with expected values based on mortality rates obtained for Linqu in the 1990-1992 Chinese Cancer Mortality Survey. RESULTS: Between March 1989 and July 2000, 39,303 person-years were accumulated; 85 new GCs occurred, 29 (34.5%) were in early stage. Fifty-eight cases (68%) were identified at one of the screens. The number of observed deaths from GC (37) was close to the expected (36.8). The standardized mortality ratio was 1.01 (95% CI 0.72-1.37) for the entire cohort, 1.13 (95% CI 0.77-1.57) for males, and 0.65 (95% CI 0.26-1.32) for females. CONCLUSIONS: Despite high population coverage with repeated screens, no reduction in GC mortality was observed in this high-risk population in China.     

自制32P敷贴器治疗瘢痕疙瘩

目的：观察自制32P敷贴器局部敷贴治疗不同类型瘢痕疙瘩的临床疗效。 方法：105例瘢痕疙瘩患者中，39例病变厚度≤ 0.3 cm的行单纯敷贴治疗，病变厚度> 0.3 cm的66例随机分为2组，单纯敷贴组36例，手术+敷贴组30例。单纯敷贴根据病变表面积大小及形状剪取敷贴片，根据剂量率和衰变校正计算每天敷贴时间，直接贴于病变表面，每天4.0~5.0 Gy/(部位•次)，连续4 d为一疗程，每疗程间隔4周，总治疗4~6个疗程。幼儿单次剂量控制在每天4 Gy/(部位•次)以下。手术+敷贴组患者手术切除瘢痕疙瘩，待手术伤口无渗出后根据伤口形状剪取敷贴片对准伤口敷贴，剂量及疗程同单纯敷贴组。 结果：单纯敷贴治疗对病变厚度≤0.3 cm的39例瘢痕疙瘩治愈32例(82%)，总有效率98%；对病变厚度> 0.3 cm的瘢痕疙瘩单纯敷贴和手术+敷贴两组治疗总有效率分别为56%和93% ，两组差异有显著性意义(P < 0.01)，其中病程< 9个月的患者治疗有效率分别为25%和75%，病程较长患者治疗有效率分别为13%和77%。治疗过程中有26例在敷帖过程中出现局部皮肤烧灼和刺痛感，均以炉甘石洗剂局部外用处理后缓解；5例出现Ⅰ度放射性皮炎，2例出现Ⅱ度放射性皮炎，以百多邦软膏局部外用后缓解，无出现Ⅲ度以上放射性皮炎病例。治愈患者局部皮肤均有不同程度的色素沉着或皮肤颜色改变。 结论：32P敷贴治疗瘢痕疙瘩治疗安全有效，对病程较短或病变厚度小于0.3 cm的患者可单纯敷贴治疗，病程较长或病变厚度大于0.3 cm患者建议先手术后再敷贴治疗。
