ORTEGA DIAZ DE CEVALLOS, Antonio; CUEVAS MORENO, Fernando  and  AGUADO POSADAS, Eduardo. Semicircular Lipoatrophy: Our experience two years later (2007-2009). Med. segur. trab. [online]. 2009, vol.55, n.217, pp.33-40. ISSN 1989-7790.

Background and objectives: To describe and to analyze the clinical presentation and the evolution after variation of certain environmental factors, of our series of cases of semicircular lipoatrophy in job environment, with special attention to the resolution of the injury and to value the possible association with other patologies from the ethiologic point of view or if it could be part of a more complex syndrome. Patients and method: Workers attended between spring of 2007 and summer of 2009. In the first visit, we made a standardized history performing physical examination with measurement and location of the injury, laboratory parameters tests and ultrasonographic study of the presumptively affected zone. Subsequently, after having been taken the measurements recommended in companies to eliminate the static electricity, quarterly controls are included with anamnesis, physical exploration and ultrasonographic comparatives. Results: 96,7 % are women, without predominance of any age. They all work at desks with informatic material and abundant electric wired up. The locations, except for 3 cases (2 in arm and one in bottom region), were at the level of the anterolateral face of thighs and with average values of 69x20x73 cm. (heightxwidthxlength). Evolvely 6 months later 93 % of cases was showing clinical remiss (62 % complete, 3l % partial); after one year only 2 cases have not showed any variation having a 69 % of complete resolutions. None of the cases has presented any other related pathology. In the first year of control there were 36 new cases, in the second one 22 and in what takes of the third one 4. Conclusions: The clinical characteristics are superimposable on those of other published series as for manifestations, type of affected worker and predominance of presentation in women. As for the evolution once modified the job environment, the trend is evidently to the resolution, much faster than in the published former cases where the environment had not been modified, in a great proportion of the cases. Furthermore these alterations have demonstrated a great efficiency stopping the appearance of new cases. No other pathological manifestations have been assessed than the strictly proper ones of the semicircular lipoatrophy.
