Cellular communication.

Abstract

Generally, cellular-telephone communications seem to be a valuable means for the public to communicate that an accident has occurred on highways in metropolitan areas. Response time is reduced and congestion quickly relieved. This system could be improved by making a provision in emergency call boxes for the separation of vehicle problems from true emergency calls to ensure the proper response priority. Cellular-telephone communications are a valuable adjunct to EMS radio communications for biotelemetry, when channels are overcrowded or communications are needed in a "dead" area. A system of dedicated hospital-emergency-department lines and telephone numbers is needed. Cellular telephones shouldn't be used as a primary means of providing medical control. Advance planning should be undertaken to ensure immediate access to hospital emergency departments if cellular is used for secondary purposes. The amount of communication traffic at and surrounding a multi-casualty incident or disaster may overwhelm a local cell. Priority numbers providing immediate access and bumping of non-emergency calls for emergency responders are needed. All means of communication should be coordinated by an EMS communications MCI or disaster plan.

Coding-complete genome sequence of grapevine leafroll-associated virus 13 from grapevine in California.

In this study, we report the coding-complete genome sequence of Grapevine leafroll-associated virus 13 (GLRaV-13), isolate CA8881, detected in Vitis vinifera in California, USA. The genome sequence exhibited over 95% nucleotide identity with previously reported GLRaV-13 isolates and contributed to better understanding of the genetic diversity of ampeloviruses infecting grapevine.

Selective referral to high-volume hospitals: estimating potentially avoidable deaths.

CONTEXT: Evidence exists that high-volume hospitals (HVHs) have lower mortality rates than low-volume hospitals (LVHs) for certain conditions. However, few employers, health plans, or government programs have attempted to increase the number of patients referred to HVHs. OBJECTIVES: To determine the difference in hospital mortality between HVHs and LVHs for conditions for which good quality data exist and to estimate how many deaths potentially would be avoided in California by referral to HVHs. DESIGN, SETTING, AND PATIENTS: Literature in MEDLINE, Current Contents, and First-Search Social Abstracts databases from January 1, 1983, to December 31, 1998, was searched using the key words hospital, outcome, mortality, volume, risk, and quality. The highest-quality study assessing the mortality-volume relationship for each given condition was identified and used to calculate odds ratios (ORs) for in-hospital mortality for LVHs vs HVHs. These ORs were then applied to the 1997 California database of hospital discharges maintained by the California Office of Statewide Health Planning and Development to estimate potentially avoidable deaths. MAIN OUTCOME MEASURES: Deaths that potentially could be avoided if patients with conditions for which a mortality-volume relationship had been treated at an HVH vs LVH. RESULTS: The articles identified in the literature search were grouped by condition, and predetermined criteria were applied to choose the best article for each condition. Mortality was significantly lower at HVHs for elective abdominal aortic aneurysm repair, carotid endarterectomy, lower extremity arterial bypass surgery, coronary artery bypass surgery, coronary angioplasty, heart transplantation, pediatric cardiac surgery, pancreatic cancer surgery, esophageal cancer surgery, cerebral aneurysm surgery, and treatment of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). A total of 58,306 of 121,609 patients with these conditions were admitted to LVHs in California in 1997. After applying the calculated ORs to these patient populations, we estimated that 602 deaths (95% confidence interval, 304-830) at LVHs could be attributed to their low volume. Additional analyses were performed to take into account emergent admissions and distance traveled, but the impact of loss of continuity of care for some patients and reduction in the availability of specialists for patients remaining at LVHs could not be assessed. CONCLUSIONS: Initiatives to facilitate referral of patients to HVHs have the potential to reduce overall hospital mortality in California for the conditions identified. Additional study is needed to determine the extent to which selective referral is feasible and to examine the potential consequences of such initiatives.

Risk factors for cytogenetically normal holoprosencephaly in California: a population-based case-control study.

Holoprosencephaly is a developmental field defect manifested by a spectrum of abnormalities of the forebrain and midface. Approximately 50% of holoprosencephaly cases are associated with a cytogenetic abnormality or a monogenic syndrome. Suggested risk factors for the remaining 50% of cases have been described in case reports, but have not been confirmed in systematically conducted studies. We report the results of a population-based case-control study of holoprosencephaly. Live births, fetal deaths, and terminations with a diagnosis of cytogenetically normal holoprosencephaly were identified by the California Birth Defects Monitoring Program. Telephone interviews were conducted with the mothers of 58 cases and 107 live born, nonmalformed controls. Women were questioned about their health and reproductive histories, family demographics, and exposures occurring during their pregnancies. Among nonsyndromic cases, increased risks were observed for females (OR=1.8, 95% C.I. 0.9-3.9), foreign-born vs. U.S. or Mexico-born women (OR=3.1, 95% C.I. 1.1-8.6), and women with early menarche (OR=2.3, 95% C.I. 0.9-5.7). Maternal periconceptional exposures associated with increased risks for nonsyndromic holoprosencephaly included alcohol consumption (OR=2.0, 95% C.I. 0.9-4.5), cigarette smoking (OR=4.1, 95% C.I. 1.4-12.0), and combined alcohol and smoking (OR=5.4, 95% C.I. 1.4-20.0), insulin-dependent diabetes (OR=10.2, 95% C.I. 1.9-39.4), medications for respiratory illnesses (OR=2.3, 95% C.I. 0.9-6.0), and salicylate-containing medications (OR=2.5, 95% C.I. 0.8-7.9). These findings are consistent with risk factors identified in some previous reports, and identify several new potential risk factors that require confirmation in future studies.
