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.     

Update on the management of neuromuscular block: focus on sugammadex

Steroidal neuromuscular blocking agents (NMBAs), such as rocuronium, are widely used in clinical anesthesia and emergency medicine to facilitate endotracheal intubation and artificial ventilation and to allow surgical access to body cavities. Reversal of neuromuscular blockade is important for the acceleration of patient recovery and prevention of postoperative residual neuromuscular blockade and reduces the incidence of severe morbidity and mortality associated with anesthesia management. Sugammadex is the first selective relaxant binding agent (SRBA) and has been designed to reverse the steroidal neuromuscular blocking drug rocuronium. Encapsulation of the rocuronium molecule by sugammadex results in a rapid decrease in free rocuronium in the plasma and subsequently at the nicotinic receptor at the motor endplate. After encapsulation, rocuronium is not available to bind to the nicotinic receptor in the neuromuscular junction. This promotes the liberation of acetylcholine receptors, and muscle activity reappears. This new concept of reversal of neuromuscular block induced by rocuronium (or vecuronium) led to impressive results in animal and phase 1 and 2 studies. Sugammadex is currently in phase 3 clinical studies and may be commercially available by 2008.     

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.     

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.
