Intussusception is a rare condition in adults, representing only 1% of all bowel obstructions. In adult cases, operative explorations are recommended to treat the bowel obstruction and to diagnose underlying diseases. The objective of the current case report was to describe the successful treatment of ileocolic intussusception with air enema reduction in an adult patient. A previously healthy 21-year-old woman had a 20-hour history of colicky abdominal pain and vomiting and was diagnosed as having idiopathic ileocolic intussusception by abdominal computed tomography. We treated the patient with air enema reduction under fluoroscopic guidance instead of an operative procedure. She received oxygen and intravenous midazolam to provide some degree of pain relief. Air was carefully pumped manually into the rectum, and the air pressure was monitored with a manometer. Because of air leakage from the rectum through the void to the outside the body, we continued to provide air to maintain the air pressure between 40 and 60 mm Hg. Three minutes after initiation of the air enema, when the patient experienced increasing abdominal pain and vomiting, the pressure was temporarily increased to greater than 100 mm Hg, and the air reached the terminal ileum. We considered the reduction successful and confirmed it with an abdominal ultrasound examination. We believe that air enema reduction is effective for treating idiopathic intussusception within 24 hours of symptom onset in young, previously healthy adult patients.

A 62-year-old Japanese 'kawara' (ceramic roof tile) craftsman presented with acute kidney injury and haemoptysis. This case met the systemic lupus erythematosus and microscopic polyangiitis criteria, with high titres of myeloperoxidase-antineutrophil cytoplasmic antibody (570 EU). Results showed the presence of antinuclear antibody at a high titre (1:2560), but detection of rheumatoid factor, anti-dsDNA, anti-SSA and anti-SSB antibodies was not apparent. This serology was similar to drug-induced, silicon-induced or silica-induced autoimmunity. The patient had been exposed to silica for > 40 years. The environmental aetiology of autoimmune diseases should be considered in cases that show atypical epidemiology and serology.
RESUMO
The present study was conducted to investigate the effects of Ga-Al-As laser irradiation on the mineralization ability of human dental pulp (HDP) cells. HDP cells in vitro were irradiated once with a Ga-AL-As laser at 0.5 W for 500 s and at 1.0 W for 500 s in order to investigate free radicals as one mechanism for transmission of laser photochemical energy to cells. Production of the hydroxyl radical (*OH) was measured using the ESR spin-trapping method and was found to be increased by laser irradiation. The DMPO-OH was not detected in the presence of dimethyl sulfoxide (DMSO), a *OH scavenger. The formation of calcification nodule was also investigated by von Kossa staining. The number of calcified nodules was increased by 1.0 W-laser irradiation. Alkaline phosphatase (ALP) activity was higher in the 1.0 W-laser irradiation group. Expression of mRNAs for heat shock protein 27, bone morphogenetic proteins (BMPs) and ALP were greater in the 1.0 W-laser irradiation group. Expression of BMPs in the conditioned medium was also higher in the 1.0 W-laser irradiation group. In particular, DMSO decreased the number of calcified nodule produced by 1.0 W-laser irradiation. These results supposed that the mineralization of HDP cells is stimulated by laser irradiation, and that *OH generated by laser irradiation is a trigger for promotion of HDP cell mineralization.
