Ischemic monomelic neuropathy: An under-recognized complication of hemodialysis access

During the past 3 years six episodes of ischemic monomelic neuropathy (IMN) have been identified in five patients as a complication of upper extremity dialysis grafts. All patients had long-standing insulin-dependent diabetes, peripheral neuropathy, and brachial artery graft origins, whereas 60% had peripheral vascular disease. Five episodes occurred immediately after graft placement, whereas one was due to a graft-related thromboembolus. Diagnostic delay was common with initial findings attributed to anesthesia, positioning, or surgical trauma. Electrophysiologic studies showed underlying diabetic neuropathy with severe multifocal neuropathy distal to the grafts. Digital pressure indices were reduced but there was no critical ischemia. In three cases ischemia was completely corrected with improvement in one. One patient had proximal balloon angioplasty with no improvement and of the two untreated patients, one improved slightly. Ischemic monomelic neuropathy is a rare but disabling complication of dialysis access in diabetic uremic patients. Its occurrence is unpredictable and diagnostic delay is common. Correction of ischemia is indicated but usually does not improve the neuropathy. Prevention requires further research to more accurately characterize the patients at risk.Presented at the Twelfth Annual Meeting of the Southern California Vascular Surgical Society, Coronado, Calif., September 17–19, 1993.     

紫外分光光度法同时测定增效黄连素胶囊中二组分含量

本文提出以紫外分光光度法测定增效黄连素胶囊含量。样品经乙醇溶解、水稀释后，不经分离提取，直接在３４６ｎｍ波长处测定盐酸黄连素；在３４６ｎｍ和２７１ｎｍ波长处以系数倍率法测定甲氧苄氨嘧啶，测得二组分的平均回收率分别为９９．１％和９９．６％，相对标准偏差为０．６７％和０．８２％（ｎ＝９）．本法简便，快速，适用于增效黄连素胶囊的常规分析．     

乌拉坦对大鼠肾脏滤过功能的影响

以９９ｍＴｃ－ＤＴＰＡ颈静脉“弹丸”式注入，用ＳＰＥＣＴ技术研究乌拉坦麻醉大鼠的肾脏滤过功能。结果表明乌拉坦麻醉大鼠肾脏滤过功能明显降低（Ｐ＜０．０５），与给药途径无关。     

长泰乐口服液治疗成人急性感染性腹泻45例临床观察

长泰乐生物保健口服液是一种新型腹泻治疗药物，用该药治疗感染性腹泻４５例，与用氟哌酸治疗的对照组比较，结果表明疗效相近，且比后者使用安全。我们认为该药可代替抗生素用于治疗感染性腹泻轻、中型患者，尤其适用于老年、孕妇和儿童。对非感染性腹泻有良好的治疗前景。     

Infantile depression,nonorganic failure to thrive,and DSM-III-R: A different perspective

A controversy exists regarding the classification of nonorganic failure to thrive within the psychiatric nomenclature. There are a number of DSM-III-R diagnoses that may be applied to NOFTT, including Reactive Attachment Disorder of Infancy (RADI) and Major Depressive Disorder (MDD). The behaviors characteristic of NOFTT are symptomatic of depression, and are similar to those exhibited by infants with anaclitic depression as well as those of the adult with depression. The correspondence of the behaviours of NOFTT and the DSM-III-R criteria for Major Depression are reviewed, as are the conceptual and therapeutic reasons to view NOFTT infants as suffering from Depression.     

Evaluation of Tissue-Engineered Skin (Human Skin Substitute) and Secondary Intention Healing in the Treatment of Full Thickness Wounds after Mohs Micrographic or Excisional Surgery

BACKGROUND: Human Skin Substitute (Apligraf, Organogenesis, Inc., Canton, MA) is a bi-layered tissue-engineered living biological dressing developed from neonatal foreskin. It consists of a bovine collagen matrix containing human fibroblasts with an overlying sheet of stratified human epithelium containing living human keratinocytes. Human Skin Substitute (HSS) appears to be immunologically inert, and has shown usefulness in the treatment of chronic and acute wounds. OBJECTIVE: Primary objectives were to evaluate the safety and efficacy of HSS in the treatment of full-thickness wounds in a prospective case series. Secondary objectives were to determine the rate of complete wound reepithelialization, incidence of complete wound healing, pain at wound site, overall cosmetic outcome, and patient satisfaction. METHODS: Fourteen patients were enrolled in the study, of which 12 were evaluable. HSS was applied in a blinded fashion to 6 of the patients immediately following Mohs or excisional surgery for skin cancer. The remaining 6 patients were allowed to heal by secondary intention. Both groups were evaluated at weekly appointments until complete reepithelialization occurred. During each evaluation, wound quality was assessed through the Vancouver Burn Scar Assessment Scale by the investigator and an independent blinded dermatologist. The investigator, blinded observer, and patient further evaluated the cosmetic outcome of the wound through the use of a Visual Analog Scale over a 6-month period. RESULTS: HSS patients and secondary intention patients were equivalent in comorbid factors such as pain, erythema, edema, exudate, infection, or hematoma between the groups. The incidence of complete wound healing at 6 months was 100% for both groups. Both groups also appeared to heal at similar rates, as defined by the complete reepithelialization of the wound. HSS patients ultimately resulted in more pliable and less vascular wounds as defined by the Vancouver Burn Scar Assessment Scale. Patient satisfaction with cosmetic outcome in both groups was positive at 6 months. CONCLUSIONS: HSS appears to be a safe, well-tolerated biological dressing with equivalent comorbid factors to secondary intention healing. HSS, however, seems to produce a more pliable and less vascular scar than those developed through healing by secondary intention. HSS also appears to produce more satisfactory cosmetic results when compared to secondary intention healing.     

银屑病患者血清一氧化氮、一氧化氮合酶、总抗氧化能力、维生素E水平的变化

目的：了解血清一氧化氮（NO）、一氧化氮合酶（NOS）、总抗氧化能力（TAO）、维生素E（VitE）水平的变化在银屑病患者病理过程中的意义。方法：对48例寻常型银屑病患者（进行期36例，静止期12例）、30名健康对照者分别采用硝酸还原酶法、分光光度法、比色法检测血清NO、NOS、TAO、VitE水平。结果：患者组的血清NO、NOS、TAO水平高于对照组（P＜0．01），患者组血清VitE水平低于对照组（P＜0．01）；进行期患者NO、NOS水平高于静止期患者（P＜0．05），而TAO、VitE水平在进行期与静止期患者间无差异（P＞0．05）。结论：NO、NOS、VitE、TAO在银屑病的病理过程中可能具有一定作用。     

1996-2000年某医院五种恶性肿瘤例均住院费用分析

恶性肿瘤是给群众带来严重健康损害的经济负担的疾病之一,已经列居我国城市 疾病死亡原因的第一位。本研究利用医院为基础的五种恶性肿瘤住院患者的费用数据,分析1996-2000年五种恶性肿瘤患者例均住院费用的变化趋势,比较自费患者和公费患者之间的例均费用差异。根据恶性肿瘤费用水平高、增长幅度快,且公费患者费用明显高于自费患者的情况,提出在医疗保障制度改革的社会环境下,医院必须加强病种费用管理,主动控制医疗费用水平。
