Factors leading to long-term hospitalization after laparoscopic appendectomy.

BACKGROUND: Randomized studies demonstrate that laparoscopic appendectomy yields better results compared with open techniques. We sought to identify factors that determine an extended hospital stay among patients undergoing laparoscopic appendectomy. METHODS: This was a prospective study including 669 patients undergoing laparoscopic appendectomy. We analyzed variables that can predict the length of hospital stay. RESULTS: Of 669 patients undergoing laparoscopic appendectomy, 141 stayed in the hospital for > or = 5 days (Group 1), and 97 stayed in the hospital for < or = 1 day after surgery (Group 2). The univariate analysis demonstrated that fever (P<0.0001), nausea and vomiting (P=0.060), leukocytosis (P<0.0001), gangrened or perforated intraoperative appearance of the appendix (P<0.0001), and appendix position behind the ileocecal junction (P<0.001) were related to a longer hospital stay. The multivariate analysis through logistical regression showed that the factors independently and significantly associated with an extended hospital stay were presurgical fever, appendix position behind the ileocecal junction, and intraoperative gangrened or perforated appearance of the appendix. CONCLUSION: Fever, appearance, and position of the appendix are factors related to an extended hospital stay.     

战士体内VitB_1、VitB_2储备水平检测

选择南方热区某特种部队战士５２人，分两组分别口服５ｍｇＶｉｔＢ１和ＶｉｔＢ２，收集４ｈ尿液，用荧光法进行负荷试验。结果：ＶｉｔＢ１组，所测２９人中，１５人缺乏，９人不足，２人正常，３人充裕；ＶｉｔＢ２组，所测２３人中，１１人缺乏，１２人不足，反映该部队全年约５％的发病是由于ＶｉｔＢ１、ＶｉｔＢ２缺乏不足所致。其原因为膳食摄入不够     

小鼠暴露在不同海拔梯度下脑含水量改变及其与脑水肿的关系

观察了小鼠暴露在不同海拔梯度下脑含水量改变及其与脑水肿的关系。实验结果表明，小鼠由低海拔区快速进入高海拔区后脑组织的湿干比值和含水量均有增高（Ｐ＜００１），以进入高海拔区后的第７ｄ为最高峰。组织学观察表明，此时脑神经细胞肿胀，胞浆内有空泡变性，胶质细胞和微血管周围有明显空晕。以上结果揭示，由低海拔区快速进入高海拔区后可致脑水肿形成。

The change process in alcoholics: client motivation and denial in the treatment of alcoholism within the context of contemporary nursing

Despite being constantly cited as a critical intervening variable in the recovery from alcohol problems, there is a paucity of literature on client motivation. This paper reviews the current literature which impacts on motivation and its importance in treatment and develops in a stepwise manner the revised expectancy/motivation hypothesis, tentatively explaining both motivation and denial as a natural process in behavioural change. Because of the revised expectancy/motivation hypothesis' distinctly defined stages which closely relate to the process of nursing and the qualitative and quantitative measurement it entails which the nursing process demands, it offers a particularly appropriate model for treatment within nurse practice.     

Systemic necrotizing vasculitis associated with childhood sarcoidosis

Childhood sarcoidosis is a rare disorder with protean manifestations. The case of a child with prolonged fever, hepatosplenomegaly, pancytopenia, and systemic necrotizing vasculitis manifesting as fever, rash and skin infarctions, digital pregangrene, and foot drop is reported. This is the first case of systemic necrotizing vasculitis reported in sarcoidosis. The fulminant course of the disease required treatment with intravenous pulsed cyclophosphamide and high doses of corticosteroids. The spectrum of vasculitis in childhood and adult sarcoidosis is reviewed.
