Patients with Alcohol Problems in the Emergency Department,Part 1: Improving Detection*

Abstract. Medical and social problems related to alcohol use are frequently seen in the ED. Often, the tempo of emergency medicine practice seems to preclude assessment beyond that required by the acute complaint. However, detection of ED patients with alcohol problems can occur using brief screening tools. This article was developed by members of the SAEM Substance Abuse Task Force, and describes screening tools that have been used successfully to identify atrisk and dependent drinkers. Their brevity, reproducibility, and accuracy vary somewhat, but screening can be realistically performed in the busy ED setting. The early detection of patients with alcohol problems would provide the opportunity for early intervention, and may reduce subsequent morbidity and mortality in this patient population.     

Poxvirus-based vaccine therapy for patients with advanced pancreatic cancer

Purpose  

An open-label Phase 1 study of recombinant prime-boost poxviruses targeting CEA and MUC-1 in patients with advanced pancreatic cancer was conducted to determine safety, tolerability and obtain preliminary data on immune response and survival.     

Keeping the focus on public health: the struggles of a tobacco prevention task force.

This case study examines a nonlegislative task force as it struggled to reach internal consensus despite external political constraints. The study highlights the convergence of politics and science, revealing complex issues likely to be confronted by advocates and public health officials. Three themes capture participants' experiences: context, sizing up the opportunities and constraints; task force process, tacit strategy to operate outside the political context and play the science card; and aftermath, a glass half full. The task force took advantage of ambiguous parameters, crafting a comprehensive statewide plan to reduce tobacco use and breaking out of the common public health paradigm of allowing budget considerations to drive program design. These internal victories could not sustain a policy success in the legislature. However, the group's product sets science-based standards for future program development, and the task force's process provides valuable insights into other states developing tobacco prevention and control policies.     

Is there a role for laparoscopic appendectomy in pediatric surgery?

Although laparoscopic procedures are currently in vogue in general surgery, the role of this approach in children has not been prospectively evaluated in the United States using the new instrumentation now available to us. To assess the value of laparoscopic appendectomy (LA) in childhood, we prospectively compared 14 LAs with 50 open appendectomies (OA) over 6 months in a single children's hospital. Antibiotic usage was at the discretion of the surgeon regardless of the procedure performed and was not different between groups. LA was performed under the direction of a single laparoscopy-trained surgeon and patient selection was based on parental consent. A three-puncture LA technique was used; children from this group were allowed to return to full activities as soon as they were comfortable. There were no significant differences between groups for severity of disease, age, weight, hospital cost, or complications. The types of complications that developed were comparable in both groups. The percent of complicated appendicitis (gangrene or perforation) was 32% in the OA group and 36% in the LA group. Patients in the LA group spent significantly fewer days in the hospital and returned to unrestricted activities (school, athletics, etc) faster than patients in the OA group. LA is approximately $1,000 more expensive than OA, the differences being easily explainable by the cost of the disposable supplies necessary for the procedure (laser fibers, trocars, etc), but because of the shorter hospital stay in the LA group the mean total cost for each group was comparable. These data suggest that although there appears to be no cost advantage, LA shortens the hospital stay and allows children to return to unrestricted activity sooner than OA.(ABSTRACT TRUNCATED AT 250 WORDS)     

Measurement of Perceived Disruption During Rebuilding Following Hurricane Andrew

The purpose of this study was to develop and evaluate a measure of perceived disruption during rebuilding following a disaster. Two eight-item scales, which measured intensity of disruption during the entire repair phase (Intensity-RP) and intensity of disruption during the past month (Intensity-PM) were developed and administered to 135 survivors of Hurricane Andrew. At 9 to 12 months postdisaster, Intensity-RP and Intensity-PM were both significantly associated with scores on the Global Severity Index of the SCL-90-R, and with scores on the Impact of Event-Intrusion Scale; Intensity-PM alone was significantly associated with PTSD scores. Regression analyses indicated that each scale contributed significant unique variance in predicting mental health symptoms, even after controlling for relevant demographic and initial disaster exposure variables.     

Neural substrates of semantic memory.

Semantic memory is described as the storage of knowledge, concepts, and information that is common and relatively consistent across individuals (e.g., memory of what is a cup). These memories are stored in multiple sensorimotor modalities and cognitive systems throughout the brain (e.g., how a cup is held and manipulated, the texture of a cup's surface, its shape, its function, that is related to beverages such as coffee, and so on). Our ability to engage in purposeful interactions with our environment is dependent on the ability to understand the meaning and significance of the objects and actions around us that are stored in semantic memory. Theories of the neural basis of the semantic memory of objects have produced sophisticated models that have incorporated to varying degrees the results of cognitive and neural investigations. The models are grouped into those that are (1) cognitive models, where the neural data are used to reveal dissociations in semantic memory after a brain lesion occurs; (2) models that incorporate both cognitive and neuroanatomical information; and (3) models that use cognitive, neuroanatomic, and neurophysiological data. This review highlights the advances and issues that have emerged from these models and points to future directions that provide opportunities to extend these models. The models of object memory generally describe how category and/or feature representations encode for object memory, and the semantic operations engaged in object processing. The incorporation of data derived from multiple modalities of investigation can lead to detailed neural specifications of semantic memory organization. The addition of neurophysiological data can potentially provide further elaboration of models to include semantic neural mechanisms. Future directions should incorporate available and newly developed techniques to better inform the neural underpinning of semantic memory models.     

TNO-6 has no effect in gastrointestinal cancer: N-acetyl-glucosaminidase shows renal damage

Twenty-five patients, 16 with gastric cancer and nine with colonic cancer, received TNO-6 30 mg m-2 every four weeks. No objective tumour response was recorded. Nausea and vomiting occurred in 21 patients and was severe in 17. Severe marrow suppression developed in five patients. Renal function was unaffected in all but one patient who developed renal failure, probably as a result of septicaemia. However, the renal tubular enzyme N-acetyl-beta-D-glucosaminidase was measured in six patients and showed a rise in all. In this study TNO-6 had no anti-tumour activity in gastrointestinal malignancy, but produced significant renal tubular damage.     

An intervention for multiethnic obese parents and overweight children.

The purpose of this pilot study was to determine the effects of the addition of coping skills training for obese multiethnic parents whose overweight children were attending a weight management program. At 6 months, parents in the experimental group had significantly lower body mass index (BMI) and body fat percentage (BFP) and higher numbers of pedometer steps compared with those in the control group. Parents in the experimental group also demonstrated significant improvement in interpersonal relationships, behavior control, and stress management compared with those in the control group. Children in the experimental group demonstrated trends toward decreased BMI and BFP and increased pedometer steps.
