Dengue fever in malaria endemic areas.

OBJECTIVE: To determine the clinical presentation and frequency of dengue fever in patients presenting with acute febrile illness. DESIGN: Observational study. PLACE AND DURATION OF STUDY: Combined Military Hospital, Attock in collaboration with Armed Forces Institute of Pathology, Rawalpindi from November 2003 to October 2004. PATIENTS AND METHODS: Patients presenting with acute febrile illness were screened for clinical features of dengue fever (DF). Dengue specific IgM was performed in clinically suspected cases. In addition, peripheral smear for malarial parasites and complete blood counts were performed. RESULTS: Eight hundred patients with fever of less than 2 weeks duration were encountered. Twenty-two (2.75%) presented with the characteristic features of DF. Dengue specific IgM was detected in 11 patients (50%). Nine out of 11 (81.8%) dengue specific IgM positive patients were also positive for malarial parasites on peripheral smear. Out of 11 DF patients, 8 patients (78%) were cured and 3 (28%) died. CONCLUSION: Dengue fever should be suspected if patient presents with bleeding manifestations, retrobulbar headache, severe myalgias and/or thrombocytopenia. Malaria and dengue may co-exist; dengue should be excluded in clinically suspected cases by laboratory investigations. Furthermore, surveillance strategies, preventive measures and healthcare workers' education is critical for curtailing this problem.

Prevalence and correlates of diarrhea.

OBJECTIVE: The present study aimed to estimate the prevalence of acute diarrhea and its correlates in remote rural villages of south Pakistan. METHODS: The authors selected 1878 children less than 3 years of age through stratified random sampling from 64 villages having the number of children enrolled proportionate to the size of each village, in rural Sindh, Pakistan. Trained field workers completed child physical measurements and maternal interviews. RESULTS: Among the children examined, 961 (51%) had diarrhea in the preceding 14 days prior to the date of survey. The prevalence of diarrhea was marginally higher among girls than boys (53% versus 49%, odds ratio 1.18, 95% CI 0.98, 1.41). The factors related with higher prevalence of diarrhea were lack of education of mother, lack of exclusive breast feeding, breast feeding for less than one year, roundworm infestation, low weight-for height, night blindness, female sex and number of older siblings more than 2 in the family. CONCLUSION: This study demonstrated that the acute diarrhea is major problem among children in rural Pakistan. Appropriate intervention programmes should be formulated focused on identified risk factors.

Innovative surveillance methods for rapid detection of disease outbreaks and bioterrorism: results of an interagency workshop on health indicator surveillance.

A system designed to rapidly identify an infectious disease outbreak or bioterrorism attack and provide important demographic and geographic information is lacking in most health departments nationwide. The Department of Defense Global Emerging Infections System sponsored a meeting and workshop in May 2000 in which participants discussed prototype systems and developed recommendations for new surveillance systems. The authors provide a summary of the group's findings, including expectations and recommendations for new surveillance systems. The consensus of the group was that a nationally led effort in developing health indicator surveillance methods is needed to promote effective, innovative systems.

Effects on local emergency departments of large-scale urban chemical fire with hazardous materials spill.

INTRODUCTION: On 18 July 2001, a train hauling hazardous materials, including hydrochloric acid, hydrofluoric acid, and acetic acid, derailed in the city of Baltimore, Maryland, resulting in a fire that burned under a downtown street for five days. Firefighters were stymied in their efforts to extinguish the fire, and the city was subjected to thick smoke for several days. OBJECTIVES: To determine whether an urban chemical fire with a hazardous materials spill resulted in a detectable public health impact, and to demographically describe the at-risk population for potential smoke and chemical exposure. METHODS: The United States Centers for Disease Control and Prevention (CDC) was consulted about possible side effects from chemical exposure. Total numbers of emergency department (ED) patients and admissions from 15:00 hours (h), 15 July 2001 to 15:00 h, 21 July 2001 were collected from five local hospitals. Patient encounters citing specified chief complaints from 15:00 h, 15 July to 15:00 h, 18 July (pre-accident) were compared with the period from 15:00 h, July 18 to 15:00 h, 21 July (post-accident). Data were analyzed using Fisher's exact test. The United States Census Bureau's Topologically Integrated Geographic Encoding and Referencing (TIGER) digital database of geographic features and ArcView Geographic Information Systems (GIS) were used to create maps of Baltimore and to identify populations at-risk using attribute census data. RESULTS: There were 62,808 people residing in the immediate, affected area. The mean of the values for age was 33.7 +/- 3.2 years (standard deviation; range = 16 yrs) with 49% (30,927) males and 51% (31,881) females. A total of 2,922 ED patient encounters were screened. Chief complaints included shortness of breath, pre-event = 109 vs. post-event = 148; chest complaints = 90 vs. 113; burns and/or skin irritation = 45 vs. 42; eye irritation 26 vs. 34; throat irritation = 33 vs. 27; and smoke exposure = 0 vs. 15. There was a statistically significant increase (p < 0.05) for shortness of breath and smoke exposure-related complaints. No statistically significant increase in numbers of admitted patients with these complaints was found. CONCLUSIONS: In the setting of a large-scale urban chemical fire, local EDs can expect a significant increase in the number of patients presenting to EDs with shortness of breath and/or smoke inhalation. Most do not require in-patient hospitalization. Careful assessment of impact on local EDs should be considered in future city-accident planning. Some official warnings were widely misinterpreted or ignored. Public education on potential hazards and disaster preparedness targeted to populations at-risk should receive a high priority. Geographic information systems (GIS) may serve as useful tools for identifying demographics of populations at-risk for disaster planning and responses.

Panel 2.3: gender dimensions and human rights aspects to responses and recovery.

This is a summary of the presentations and discussion of the Gender Dimensions and Human Rights Aspects to Responses and Recovery of the Conference, Health Aspects of the Tsunami Disaster in Asia, convened by the World Health Organization (WHO) in Phuket, Thailand, 04-06 May 2005. The topics discussed included issues related to gender dimensions and human rights pertaining to the responses to the damage created by the Tsunami. It is presented in the following major sections: (1) gaps encountered and major issues; (2) limitations of response; (3) what could have been done better?; and (4) recommendations.
