Angiodysplasia as the cause of massive lower gastrointestinal hemorrhage in a young adult

PURPOSE: This study was undertaken to clarify the importance of bleeding vascular ectasia of the colon as the etiology of massive lower gastrointestinal hemorrhage in patients 40 years of age or younger. METHODS: An otherwise healthy 21-year-old male was admitted to a tertiary medical center with massive lower gastrointestinal hemorrhage. Technetium-labeled red blood cell scan, selective visceral angiography, and colonoscopy identified the source of bleeding as vascular abnormality of the descending colon. Segmental colonic resection was performed. RESULTS: Histologic review of the specimen demonstrated a vascular ectasia. The patient recovered uneventfully and has had no further stigmata of hemorrhage. A review of the literature was undertaken to make clear the significance of vascular ectasia as the source for massive colonic hemorrhage in the young adult. CONCLUSION: This is the first report that documents histologically a vascular ectasia as the source of massive lower gastrointestinal hemorrhage in an otherwise healthy patient less than 40 years of age. Vascular ectasia is an uncommon cause of lower gastrointestinal hemorrhage in the young adult.The Chief, Bureau of Medicine and Surgery, Navy Department, Washington, DC, Clinical Investigation Program sponsored this report #84-16-1968-532, as required by HSETCINST 6000.41A.

通辽与长春两地区成人枢椎的测量

[1]目的 了解枢椎形态和结构的性别和地区差异.[2]方法 对通辽与长春两地区129套成人枢椎(男76套,女53套)进行了测量,指标包括齿突高、全高、椎体高、矢径、全宽、椎孔矢径和椎孔横径,并计算了椎体指数和椎孔指数.对所得数据进行统计学处理.[3]结果 枢椎的7项测量指标,除椎孔矢径与横径(长春地区的椎孔横径除外)以及通辽地区齿突高外,其性别差异均具极显著性(t＝2.34~7.68,p<0.01或0.05);两地区比较,除女性齿突高外,其他指标差异均无显著性(t＝0.03~1.95,p均>0.05).指数比较,除两地区女性椎体指数外,均无性别和地区间差异(t＝0.04~1.86,p均>0.05).[4]结论 通辽和长春两地区成人枢椎的形态和结构无明显差异.     

80例健康青年分别经针刺或艾灸肺俞穴后的肺功能变化

目的：探讨针刺与艾灸肺俞穴对健康人肺功能的影响。方法：我们选择了20－22岁健康男性80例，随机分为针刺组和艾灸组各40例，于针刺，艾灸前和针刺，艾灸后10min测试用力肺活量（FVC），用力呼气量（FEV1．0），最大呼气中段流速（MMF），最大呼气流量（PEFR），75％，50％，25％肺活量时的最大呼气流速（V75，V50，V25），结果：显示经针刺和艾灸肺俞穴后2组FVC，FFV1．0均显著增加，P＜0．05，2组间比较针刺组FVC明显高于艾灸组，P＜0．05，而且艾灸组MMF，V25亦显著降低P＜0．05，结论：健康人经针刺和艾灸肺俞穴后均可使大气道阻力减少，肺容量增加，提示一定量的艾燃烧后的烟雾可使健康人肺功能受到影响，使肺的小气道收缩，出现阻塞性改变。     

The Treatment of Low Grade Cerebral Astrocytomas by Radiotherapy in Queensland

The records of 108 adult patients with supratentorial low grade astrocytoma presenting between 1/1/80 and 31/12/87 were examined for the following factors which might affect survival: patient age, extent of surgical resection, site of tumour, tumour grade, radiation field size and radiation dose. Univariate analysis showed that patient age, field size and radiation dose were significant prognostic factors, but with multivariate analysis only patient age and radiation field size were significant independent variables. It is possible that field size is a proxy variable for tumour size.     

老年冠心病患者实施健康教育的远期效果分析

目的：探讨老年冠心病患者实施健康教育的远期效果。方法：110例老年冠心病患者被随机分为健康教育组（教育组）及对照组，每组各55例。在常规治疗的基础上教育组在住院期间及出院后4年内给予健康教育处方结合口头卫生宣教及科普板报知识等经常性的健康教育活动，而对照组不予健康教育。结果：教育组患者对冠心病知识的了解情况、饮食控制情况、规律服药治疗情况比对照组好（P＜0．01），出院后再次住院次数比对照组少（P＜0．01）。而情绪及吸烟量控制两组无显著性差异（P＞0．05）。结论：对老年冠心病患者实施经常性的健康教育是控制疾病恶化的重要措施。     

温州口岸出入境人员心房颤动分析

Special needs of adolescent and young women in accessing reproductive health: promoting partnerships between young people and health care providers.

This article considers the unique challenges and opportunities that health care providers (HCPs) face when they address the sexual and reproductive health and rights of young women accessing services. Some of the difficulties that HCPs encounter in their work are highlighted, including poor remuneration, the impact of their personal biases and the effect of an under-equipped working environment. The financial, logistical and emotional challenges young people face in accessing services are also described, as well as some small changes that could promote fruitful partnerships between HCPs and their young clientele. Also considered is how international documents concerning reproductive health can be utilized as advocacy tools to ensure that, when governments speak of making young people's needs a priority, resources are also made a priority-so that reproductive health can become a reality for all young people.     

Age determines memory for face identity and expression

Background: The recognition of facial expressions is an important component of emotion processing which contributes to interactional behavior. One of the factors highly associated with potential decline of ability in behavioral tasks is age. Methods: We have investigated age‐related changes in facial identity and expression memory of healthy subjects in three age groups: young adults (20–40 years), elderly adults (60–80 years) and, for the first time in the literature, very old adults (over 80 years of age). Using a picture test, photographs of faces with happy or angry expressions were presented to study participants during the encoding task, and the memory for identity and emotional facial expression was investigated in a subsequent recognition task showing emotionally neutral faces. Half of the faces presented in the recognition task were initially shown in the encoding task. Results: Age interacted with the memory process: the ability to recognize both facial identity and emotional expression declined with advanced age. Happy facial expressions were better recognized in all age groups. Although there was a continuous overall decrease in recognition of both happy and angry expressions with advanced age, the effect favoring happy facial expressions was stable also in very old adults. Other factors such as gender or educational level did not affect the memory process for facial expressions. Conclusions: Our findings suggest that age is a significant determinant of memory for facial identity and emotional expression, and that, similar to younger adults, the recognition process of the elderly favors happy emotional facial expressions.
