We investigated 352 patients with acute poisoning, 145 males and 207 females, who were sent to the Department of Emergency and Critical Care Center between June 1999 and March 2004. The insurance application rate averaged 72.5%. The causative agents included 98 prescribed drugs, 23 pesticides and herbicides, cyanide, arsenic and boric acid. Hypnotic and psychotropic drugs accounted for 192 cases (47.5%); antipyretics and analgesics, 93 (23.0%); pesticides and herbicides, 65 (16.1%); amphetamine-like drugs, 6 (1.5%); boric acid, 4 (1.0%); cyanide, 3 (0.7%); arsenic, 1 (0.2%); and other agents, 40 (9.9%). In young people, the most prevalent cause of poisoning was hypnotic,or psychotropic drugs prescribed in psychiatry clinics. In people older than 30, poisoning due to pesticides and herbicides was increased, reaching a peak among those in their 40s. Of 23 patients who died, 20 took Paraquat and Diquat, 2 took organophosphates and 1 took an overdose of antidepressants. The other 329 were transferred to different medical departments or were discharged from our hospital after recovery.

OBJECTIVE: To investigate the factors leading to the retreatment for tuberculosis. MATERIALS: Forty-seven retreatment cases with pulmonary tuberculosis, who were discharged from the National Chiba Higashi Hospital from 2000 to 2002. METHODS: Data on all retreatment cases were studied as to the condition of the original treatment and factors leading to the retreatment. RESULTS: Of the 47 cases, 33 cases received the original treatment in our hospital. Of the 33 cases, 24 cases were relapsed cases and 9 cases were defaulters. Most relapsed cases were male aged 50s and 12 cases (50%) were jobless. As the factors leading to retreatment, the delay in the negative conversion of sputum culture accounted for 11 cases (45.8%) out of 24 cases. No specific factors were found in three cases (12.5%). Among the defaulters, no bias was seen as to age and occupation of cases, but all the cases were male, and they defaulted during the maintenance phase of treatment at the out-patient department. CONSIDERATION: The delay in the negative conversion of sputum culture was the main factor relating to the relapse. Diabetes mellitus (DM) is one of the factors leading to the relapse, but many factors were observed in DM patients. Male cases aged 50s had many factors leading to the relapse. An intensive management for out-patients and involvement of welfare department aiming at the completion of treatment for the socially vulnerable groups might be necessary as the measure to prevent defaulting. CONCLUSION: The delay in the negative conversion of sputum culture was the main factor leading to relapse, and intensive management for out-patients aiming at the completion of treatment is necessary to prevent the defaulting.
