Fatal lightning strikes in Malaysia.

Area of Science:

• Forensic Pathology
• Environmental Health
• Public Health

Background:

• Lightning strikes are a significant cause of death from environmental phenomena.
• The passage of lightning current through the body can affect multiple organ systems.
• Understanding the epidemiology of lightning-related fatalities is crucial for prevention strategies.

Purpose of the Study:

• To analyze the characteristics of fatal lightning strike cases over a 10-year period.
• To identify demographic, occupational, and situational factors associated with lightning fatalities.
• To determine the most commonly affected body parts in fatal lightning strike incidents.

Main Methods:

• A retrospective study of autopsy reports from University Hospital Kuala Lumpur and Hospital Tengku Ampuan Rahimah, Klang.
• Inclusion of 27 fatal lightning strike cases from 1996 to 2005, with additional data from the last three years of the study period.
• Analysis of demographic data, victim occupation, circumstances of the strike, and autopsy findings.

Main Results:

• A total of 27 fatal cases were identified, with a strong male preponderance (92.59%) and a male to female ratio of 12.5:1.
• The majority of victims were foreign workers, predominantly Indonesian construction workers aged 30-39, often struck in the evenings.
• Head and neck were the most frequently affected areas (77.78% and 74% respectively), with 37.04% of victims being brought in dead.

Conclusions:

• Fatal lightning strikes in this study population primarily impacted adult males, particularly foreign construction workers, highlighting occupational and demographic risk factors.
• The findings underscore the importance of safety measures during evening hours and in open areas or under shelters during thunderstorms.
• Further research into specific injury patterns and preventative interventions is warranted to reduce lightning-related mortality.
