Support for the hypothesis that electro-stimulation is responsible for Lipoatrophia semicircularis

Area of Science:

• Dermatology
• Environmental Health
• Occupational Medicine

Background:

• Lipoatrophia semicircularis (L.s.) is an idiopathic condition causing semicircular skin impressions, primarily on the thighs.
• Recent years have seen an outbreak of L.s., predominantly affecting female office workers using computers and electrical devices.
• The condition is often diagnosed after occupants move into new or renovated office buildings.

Purpose of the Study:

• To investigate the underlying causes of Lipoatrophia semicircularis.
• To evaluate existing hypotheses including mechanical pressure, circulatory issues, thermal exchange, and electrical phenomena.
• To present new data supporting an electrical origin for L.s.

Main Methods:

• Review of existing literature and hypotheses regarding L.s. etiology.
• Analysis of case studies and environmental factors in affected office settings.
• Correlation of L.s. occurrence with specific electrical parameters and environmental conditions.

Main Results:

• Existing hypotheses involving mechanical pressure, circulation, and thermal exchange appear invalidated by experience.
• Electrical factors, including electric devices, cable types, desktop conductivity, ionizers, and relative humidity, are strongly implicated.
• L.s. is likely not caused by electrostatic discharges but potentially by electro-stimulation phenomena, such as air ion formation and subsequent skin discharges.

Conclusions:

• The electric environment in offices is a significant factor in the development of Lipoatrophia semicircularis.
• Controlling the office electrical environment is crucial for minimizing L.s. risk.
• Further research into electro-stimulation mechanisms is warranted to fully understand L.s. pathogenesis.
