METHODS: We studied 100 patients with pulmonary TB treated with anti-TB drugs including INH. The frequencies and distributions of single nucleotide polymorphisms, haplotypes, and diplotypes of NAT2 were determined by the PCR-restriction fragment length polymorphism method, and the results were compared between TB patients with and without adverse effect, using multivariate logistic regression analysis.RESULTS: Statistical analysis revealed that the frequency of a variant haplotype, NAT2*6A , was signifi cantly increased in TB patients with hepatotoxicity, compared with those without hepatotoxicity [P = 0.001, odds ratio (OR) = 3.535]. By contrast, the frequency of a wild-type (major) haplotype, "NAT2*4", was signif icantly lower in TB patients with hepatotoxicity than those without hepatotoxicity (P < 0.001, OR = 0.265). There was no association between NAT2-haplotypes and skin rash or eosinophilia. CONCLUSION: The present study shows that NAT2 is one of the determinants of anti-TB drug-induced hepatotoxicity. Moreover, the haplotypes, NAT2*4 and NAT2*6A, are useful new biomarkers for predicting anti- TB drug-induced hepatotoxicity.展开更多

Although these treatment modalities can induce effectively coagulated tumor necrosis in the liver, they may cause adverse effects on extrahepatic abdominal organs. There are, however, no published reports on the influence of percutaneous local therapies on the gastric myenteric activity. Therefore, it is unclear whether or not gastric function is affected by percutaneous local therapies. In this study, to make clear the effect of PEI and RFA on the gastric function, we continuously recorded the gastric myoelectric activity by electrogastrography (EGG) and estimated the effect of percutaneous local therapies for HCC on gastric function.展开更多

METHODS: Since August 2001, we performed the perineal puborectalis sling operation on eight patients with idiopathic fecal incontinence. A specially designed polyester mesh sling was introduced along the puborectalis muscle, from a posterior perianal incision, running to a small suprapubic incision. The ends were tied together with moderate tension. Patients were evaluated with the Fecal Incontinence Severity Index, the Cleveland Clinic Score of Incontinence, and the Fecal Incontinence Quality of Life Scale. Manometry and defecography were performed before and six months after the operation. RESULTS: Eight patients (7 females; mean age, 63 (range, 44-77) years) were evaluated. A wound infection developed in one patient, which subsided with antibiotics. A rectal ulcer developed in one patient, necessitating sling removal. In the remaining seven patients, the Fecal Incontinence Severity Index improved from 27 to 9, and the Cleveland Clinic Score of Incontinence improved from 13 to 5 (P < 0.05). All parameters in the Fecal Incontinence Quality of Life Scale improved: lifestyle from 2.1 to 3.6; coping/behavior from 1.5 to 3.4; depression/self perception from 2.3 to 3.7; and embarrassment from 2 to 3.6 (P < 0.05). No significant difference was found between preoperative and postoperative maximum resting pressure and maximum squeeze pressure. However, the median anorectal angle on defecography after the operation was significantly reduced (P < 0.05). CONCLUSIONS: We believe that the perineal puborectalis sling operation is technically feasible, with low morbidity, and can be an effective procedure for idiopathic fecal incontinence.展开更多

METHODS: Between June 2000 and January 2003, 30 females (mean age, 62 (range, 45-78) years) with a symptomatic large rectocele (> 3 cm) underwent transvaginal rectocele repair (anterior levatorplasty). Six months after surgery, a physiologic evaluation was performed by using defecography (depth of rectocele) and anorectal manometry (maximum resting pressure, maximum squeeze pressure, rectal threshold, and maximum tolerable volume). Using a questionnaire, a clinical evaluation was performed one year after surgery to analyze symptoms, including difficult evacuation, digital support, sexual discomfort, as well as patient satisfaction. Follow-up of all patients was conducted during a median duration of 38 (range, 23-54) months. RESULTS: There were no operative complications, such as hematoma, wound infection, or rectovaginal fistula. Difficult evacuation improved in 27 of 30 patients (90 percent) and completely disappeared in 9 patients. Postoperatively, digital support was no longer necessary during evacuation in 15 of 21 patients (71 percent). Overall patient satisfaction reached 25 of 30 (83 percent). Although mild sexual discomfort was observed in nine patients, it disappeared gradually and only one patient complained of persistent symptoms. No patient reported symptomatic recurrences at the end of the follow-up. The radiologic mean depth of the rectocele was significantly reduced: preoperative, 3.9 cm; postoperative, 0.5 cm. None of the physiologic parameters significantly changed after surgery. CONCLUSIONS: Transvaginal rectocele repair can provide excellent long-term symptomatic relief and a high rate of patient satisfaction without any alteration in anorectal physiologic function.展开更多
