This is a study of decrease in both stump pain and unidentified complaints after removal of neuroma on an amputated left thigh. The patient was a 44 year old woman who received an operation after a motorcycle accident 20th of March, 1991. She started a rehabilitation program in early June of the same year. How ever the patient complained of a squeezing pain on the amputated area. This symptom became more severe after the removal of the nails in September. The pain was perceived as a mental problem and the patient was released from the previous hospital. The pain continued and on the 9th of March, 1992, the patient was introduced to our pain clinic. The patient complained about the cold sensation and pressure pain of the amputated area at the beginning. Later she also expressed various unidentified complaints. No improvement resulted after conducting an epidural block and a lumbar sympathetic ganglion block. MMPI test showed psychological instability. Local injection showed some positive effects, which led to considerations concerning the possibility of neuroma. After confirming the existence of neuroma through CT and MRI, neuromectomy was performed. After the removal of neuroma, the unidentified complaints as well as the stump pain decreased.

Air pollution from the Daegu industrial complex (Die) in Korea has been a common nuisance and cause of complaints for nearby residents. The current study measured the indoor and outdoor levels of six VOC (benzene, toluene, ethylbenzene, and three isomeric xylenes) at two residential areas with a different proximity to the ODIC, plus the ambient levels at two industrial areas within the boundary of the DDIC. The QA/QC program included the range of correlation coefficient (0.94-0.99) for calibration curves, within the permissible range. Toluene was the most abundant VOC in the ambient air both in residential and industrial areas. Both indoor and outdoor air concentrations of all target VOC except benzene were higher in residential area near the DIC compared to that further away from the DIC. Moreover, the ambient air concentrations of all target VOC except benzene for two industrial sites (A and B) were significantly higher than the outdoor or indoor air concentrations in the two residential areas. The findings further suggested that VOC ambient levels measured in a residential area near the DIC be used as a potential indicator of odor-causing unidentified air pollutants transported from the DIC. Moreover, it was found that the elevated ambient toluene levels outweighed the indoor sources with respect to the environmental exposure of residents nearby the DIC. However, in the residential area further away from the DIC, the toluene indoor sources outweighed the outdoor sources.
