目的探讨女性难治性膀胱过度活动症患者心理弹性状况及保护性因素,为改善其身心健康提供依据。方法采用心理弹性量表、症状自评量表、艾森克人格问卷、社会支持量表、焦虑及抑郁量表对80例女性难治性膀胱过度活动症患者进行问卷调查。结果女性难治性膀胱过度活动症患者心理弹性得分为(54.10±8.27)分,显著低于国内常模(P<0.05)。患者的一般情况(病程、年龄、文化程度)对心理弹性的预测作用不明显(R2=0.14,F=18.10),当社会支持、SCL-90、人格特质、SAS、SDS进入方程后,对患者的心理弹性具有较明显的预测作用(R2=0.67,△R2=0.46,F=115.22)。结论女性难治性膀胱过度活动症患者心理弹性较差,社会支持、SCL-90、人格特质、焦虑抑郁情绪是其重要的影响因素,应重视患者存在的心理问题,发掘心理弹性的保护性因素并积极干预,促进其身心健康。 相似文献

A local pedicled vascularized bone flap can prevent the morbidity and cost of free bone flap surgery in small segmental bone defects or long cartilaginous defects of the head and neck. Such flaps can also be useful in patients who are high risk for surgery. The periosteal vascularity of the mandible can be used to design islanded facial artery-based bone flaps, which can be utilized to that extent. Two patients with a small segmental mandibulectomy defect and one patient with a long cricotracheal resection defect underwent reconstruction using three different designs of islanded facial artery osteomyomucosal/osseous flap (iFOMM). The patients had a minimum follow-up period of 18 months. All flaps were successful, with satisfactory healing and without any functional deficit or disease at last follow-up. 相似文献

BackgroundDifferent studies have reported the efficacy of percutaneous tibial nerve stimulation (PTNS) and transcutaneous tibial nerve stimulation (TTNS) in treating idiopathic overactive bladder (OAB). However, no study has compared the effectiveness of PTNS and TTNS added to bladder training (BT) in idiopathic OAB.ObjectiveTo compare the efficacy of PTNS and TTNS added to BT in women with idiopathic OAB.MethodsWe randomised 60 women with idiopathic OAB into 3 groups. Group 1 (n = 19) received BT, Group 2 (n = 19) received PTNS in addition to BT, and Group 3 (n = 20) received TTNS in addition to BT. PTNS and TTNS were performed 2 days a week, for 30 min a day, for a total of 12 sessions for 6 weeks. Patients were evaluated by incontinence severity (pad test), a 3-day voiding diary (frequency of voiding, incontinence episodes, nocturia and number of pads used), symptom severity, quality of life, treatment success (positive response rate), treatment satisfaction (Likert scale), discomfort level and preparation time for stimulation (sec).ResultsAt the end of treatment; severity of incontinence, frequency of voiding, incontinence episodes, nocturia, number of pads used, symptom severity and quality of life were significantly improved in Groups 2 and 3 versus Group 1 (P < 0.0167). Treatment success and treatment satisfaction were higher in Groups 2 and 3 than Group 1 (P < 0.001 and P < 0.0167, respectively). Level of discomfort was lower, treatment satisfaction was higher and preparation time for stimulation was shorter in Group 3 than Group 2 (P < 0.05).ConclusionBoth the PTNS plus BT and TTNS plus BT were more effective than BT alone in women with idiopathic OAB. These 2 tibial nerve stimulation methods had similar clinical efficacy but with slight differences: TTNS had shorter preparation time, less discomfort level and higher patient satisfaction than PTNS. 相似文献

The first COVID-19 vaccination was given in December 2020 and there is an effort to vaccinate the international population on a massive scale. Common side effects from the vaccine include headache and tiredness. Regional lymphadenopathy has been described in relation to other vaccines. We describe two cases of supraclavicular reactive lymphadenopathy presenting in patients who had the COVID vaccination in the ipsilateral arm. Awareness of this diagnosis is important for patients presenting to the neck lump clinic. 相似文献

目的:分析比较"F"形空心钉与传统倒三角3枚平行螺钉内固定治疗青壮年Pauwels Ⅲ型股骨颈骨折的临床疗效。方法:2017年1月至2020年1月收治Pauwels Ⅲ型股骨颈骨折患者38例,根据置入钉方式的不同将其分为两组,其中A组18例,采用"F"形空心钉固定,男12例,女6例,年龄37~55岁,受伤至手术时间1~3 d。B组20例,采用传统倒三角3枚平行拉力螺钉固定,男12例,女8例,年龄35~55岁,受伤至手术时间为1~3 d。比较两组患者骨折不愈合,股骨头坏死,股骨颈短缩,空心螺钉退出情况,髋关节功能Harris评分,疼痛视觉模拟评分(visual analogue scale,VAS)。结果:所有患者获得随访,时间为15~31个月。两组患者在骨折不愈合,股骨颈短缩,股骨头坏死方面差异无统计学意义(P>0.05);两组患者在螺钉退出方面差异有统计学意义(P<0.05)。两组患者术后12个月时髋关节Harris评分及VAS评分差异均无统计学差异(P>0.05)。结论:"F"形与传统倒三角3枚平行空心钉内固定治疗青壮年Pauwels Ⅲ型股骨颈骨折中短期疗效相似,但"F"形空心钉退钉率较低。 相似文献

Infections of the ear, nose and throat are common. The majority of these infections are managed by the primary care physicians and they settle with conservative and medical management. However, a small group can progress to become troublesome and develop complications to the extent that they may require surgical intervention. Some of the infections can lead to life-threatening complications, therefore awareness and correct diagnosis along with appropriate management is paramount. Foreign bodies in the ear, nose and throat are commonly encountered. The location and type of foreign body can have an implication on the urgency of action and the possible complications. In this article the common ENT infections and foreign bodies and their management are discussed. 相似文献
