Evaluation of a mass dispensing exercise in a Cities Readiness Initiative setting.

PURPOSE: The effectiveness of a point of dispensing (POD) used in a mass dispensing exercise was evaluated. METHODS: Public Health-Seattle & King County (PHSKC), in conjunction with the University of Washington, conducted a functional exercise of mass dispensing plans to test the effectiveness of a POD. Specifically, the organization and maintenance of patient flow, staffing model, signage, and dissemination of public information were evaluated. A data collection application using cellular telephones was used to record time and patient flow data to evaluate patient flow. Questionnaires distributed to staff and volunteer patients at the end of the exercise obtained feedback regarding the setup, organization, and operations of the POD. RESULTS: The POD was operational for approximately 68 minutes. The majority of POD staff reported feeling comfortable with their specific job tasks and duties within 15 minutes of opening the doors to the POD to the public. Staff questionnaires also revealed a high level of self-reported confidence in their ability and in the ability of their colleagues to perform the job-specific responsibilities required of them or respond to this hypothetical event. The majority of volunteer patients found the signs helpful and easy to follow and the check-in form easy to complete. Despite efforts to provide patients with oral and written information about the medications being dispensed, only 80% indicated that they knew how to take the medication, and only 73% reported understanding the medication instructions for all the individuals for whom they picked up medication. CONCLUSION: The majority of volunteer patients and staff who participated in a functional exercise of mass dispensing plans found the POD to be effective. Time-flow analysis provided preliminary estimates of the total amount of time needed to complete the dispensing process for each head of household.     

Total pancreatectomy with islet autotransplantation: an overview

Pain control is one of the most challenging aspects in the management of chronic pancreatitis. Total pancreatectomy can successfully relieve the intractable abdominal pain in these patients but will inevitably result in insulin-dependent diabetes. Islet autotransplantation aims to preserve, as far as possible, the insulin secretory function of the islet cell mass thereby reducing (or even removing) the requirement for exogenous insulin administration after a total pancreactomy. Despite the relatively small number of centres able to perform these procedures, there are important technical variations in the details of their approaches. The aim of this review is to provide details of the current surgical practice for total pancreatectomy combined with islet autotransplantation, and outline the potential advantages and disadvantages of the variations adopted in each centre.     

Renal Aspergilloma--A Case Illustrating the Problems of Medical Therapy

The second documented case of renal aspergilloma due to Aspergillusflavus is presented. The merits of the medical therapy thatfailed are discussed. Pathological examination showed a nidusof aspergillus around suture material persisting from a pyelolithotomyoperation 2 years before in India. We argue that this was thereason for the failure of the medical therapy. This is the firstcase of its kind reported.     

多种血管新生指标在肝细胞肝癌中的表达及敏感性比较

目的　探讨血管新生指标CD34、CD31、vWF、Ⅳ型胶原纤维及层粘连蛋白在肝细胞肝癌(HCC)中的表达及意义 ,同时比较上述几种血管新生因子与增殖细胞核抗原 (PCNA)、病理指标及预后的相关性 ,以便筛选出有效的临床预后指标。方法　采用免疫组化方法 ,对 5 3例肝细胞肝癌的标本进行CD31、CD34、vWF、Ⅳ型胶原纤维及层粘连蛋白的染色、计数 ,并用检测数据与患者的临床资料进行统计分析。结果　统计染色的血管面积后发现 ,CD34与多种临床病理指标无相关性 ;CD31与肝内门静脉浸润相关 ;vWF与肿瘤的TNM分期及肝内门静脉浸润呈正相关 ;CollⅣ与肝内门静脉浸润呈正相关、与术后生存期呈负相关 ;Lam与肝硬化及术中出血量呈负相关、与术后生存期呈正相关。PCNA与肿瘤TNM分期有关。结论　在HCC中 ,CollⅣ、vWF、及CD31为肝细胞肝癌的有效血管新生及预后指标 ;Lam则与肝硬化及术中出血相关 ;PCNA指数肿瘤分期有关 ;CD34不能用作血管新生或预后指标     

Risk factors and their relation to initiation of alcohol use among early adolescents

This study examined the relationship between risk factors and initiation of alcohol use over a 15-month period among a cohort of 7th graders who were abstainers at the time of initial testing. The relationship between risk factors and alcohol use was examined using a discriminant function analysis. At the univariate level, rejection of parental authority, deviant behavior, and sensation seeking were statistically significant. The discriminant function retained only three of the risk factors: rejection of parental authority, deviant behavior, and religious commitment. Implications for school-based prevention programs are discussed, particularly the need to target primary prevention programs based upon adolescents' risk.
