Subfrontal schwannomas arising from the olfactory groove are rare and their origin remains uncertain because olfactory bulbs do not possess Schwann cells. We present two cases of subfrontal schwannomas treated with surgical resection. In one case, the tumor was located between the endosteal and meningeal layers of the dura mater. This rare case suggests that subfrontal schwannomas may originate from the fila olfactoria. 相似文献

Abstract Of the epileptic patients who were treated for ≥ 5 years until the end of 1990 and had more than four seizures in 1990, 63 patients had been treated without interruption until the end of 1995. We analyzed their clinical courses from 1990 to 1995 prospectively. More than half the subjects were diagnosed with temporal lobe epilepsy. Twenty cases had presumed etiology, and 32 had neuropsychiatric complications. Of the subjects whose seizures were not controlled with conventional antiepileptic drugs (AED), 11 cases demonstrated significant improvement when new AED; that is, lamotrigine, vigabatrin, clobazam, topiramate, tiagabine or CGP33101 were added. However, 10 patients did not respond to new AED. Presumed etiology, neuropsychiatric complications, multiple epileptic foci in EEG and abnormalities on head CT or MRI were characteristics of the patients whose seizures were resistant to new AED. 相似文献

Genetic variation in ABCB1 influences paclitaxel pharmacokinetics in Japanese patients with ovarian cancer 总被引:1,自引:0,他引:1
H. YAMAGUCHI† T. HISHINUMA† N. ENDO H. TSUKAMOTO Y. KISHIKAWA† M. SATO† Y. MURAI† M. HIRATSUKA‡ K. ITO§ C. OKAMURA§ N. YAEGASHI§ N. SUZUKI† Y. TOMIOKA† & J. GOTO† 《International journal of gynecological cancer》2006,16(3):979-985
Paclitaxel, an antineoplastic agent used for the treatment of ovarian cancer, is metabolized by cytochrome P450 (CYP)3A4 and CYP2C8 and is excreted from cells by ATP-binding cassette (ABCB1) (multi-drug resistance [MDR1], P-glycoprotein). Expression of these proteins is regulated by pregnane X receptor (PXR). Although there are common genetic polymorphisms in the genes encoding these proteins, their effect on the clinical efficacy of paclitaxel is unclear. We therefore examined the relationship of the paclitaxel pharmacokinetics in 13 patients with ovarian cancer to polymorphisms in CYP2C8, CYP3A5, ABCB1, and PXR. We found high interindividual variability in the plasma concentrations of two metabolites, 6alpha-hydroxypaclitaxel and p-3'-hydroxypaclitaxel. All the patients were genotyped as CYP2C8*1/*1. Neither the CYP3A5 A6986G (CYP3A5*3) nor the PXR C-25385T alleles were associated with altered plasma concentrations of paclitaxel and its metabolites. ABCB1 T-129C, T1236C, and G2677(A,T), however, was associated with lower area under the plasma concentration-time curve (AUC) of paclitaxel. We also observed a significant correlation between the AUC (r=-0.721) or the total clearance of paclitaxel (CL(tot)) (r= 0.673) and the ABCB1 mutant allele dosage in each patient. Taken together, our findings suggest that interindividual variability in paclitaxel pharmacokinetics could be predicted by ABCB1 genotyping. 相似文献

Some researchers claim that lupus anticoagulant-positive plasma may cause a false-positive reaction in the test for activated protein C (APC) resistance, a hereditary thrombophilic state characterized by abnormal factor V, which frequently causes venous thrombosis, We investigated whether anti-/32 -glycoprotein I antibody (aGPI), which has recently come to be regarded as an anti-cardiolipin antibody (aCL) itself, might have an effect on the APC resistance test. 相似文献

We previously reported that seminal vesiculitis was associated with acute epididymitis, and that Chlamydia trachomatis was the major causative pathogen for infection of the seminal vesicle, suggesting that seminal vesiculitis was a discrete disease entity. In this paper, we report two patients with bacteriologically and cytologically proven seminal vesiculitis who had asymptomatic urethritis but not epididymitis. The clinical courses of these patients suggest that chlamydial seminal vesiculitis may be a cause of asymptomatic infection of the urethra or subsequent development of acute epididymitis. 相似文献

AIM: To determine the prevalence of prostatitis-like symptoms in Japanese men living in one town. METHODS: A cross-sectional and population-based study was performed in a town that had 6385 men aged from 20 to 79 years. We sent two questionnaires, the validated Japanese version of the National Institutes of Health Chronic Prostatitis Symptom Index and the International Prostate Symptom Score (I-PSS) with questions about individual medical information, to 1424 randomly selected community-indwelling men. Subjects were defined as having prostatitis-like symptoms if they complained of perineal and/or ejaculatory pain or discomfort and their total pain score was four or greater. RESULTS: A total of 512 men (36%) responded completely to the questionnaires. Of the 512 responders, 25 men (4.9%) were identified as having prostatitis-like symptoms. Prevalence of symptoms was the same in men aged younger than 50 years (5.0%) as those 50 years and older (4.8%). The I-PSS score was 10.8 in men with prostatitis-like symptoms, which was higher than in those without symptoms. CONCLUSIONS: Prevalence of prostatitis-like symptoms was 4.9% in randomly selected men. International comparison of prevalence of the symptoms may contribute to further understanding of chronic prostatitis. 相似文献

Extragonadal germ cell tumors (EGGCT) are commonly found in the midline of the body. We report a rare case of a retroperitoneal EGGCT presenting as a bulky pelvic mass located between the left internal and external iliac arteries in a 29-year-old man. His alpha-fetoprotein level was 12946.2 ng/mL and the biopsy of the tumor revealed a nonseminomatous germ cell tumor. After three cycles of chemotherapy (bleomycin/etoposide/cisplatin) followed by resection of all residual tumors, one cycle of salvage chemotherapy (etoposide/ifosphamide/cisplatin) was added. The patient was disease free at 21-month follow up. 相似文献

AIM: The aim of this study was to investigate whether the preoperative degree of bladder outlet obstruction (BOO), detrusor underactivity (DUA) or detrusor overactivity (DO) affected the short-term outcome of transurethral resection of the prostate (TURP) for patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). METHODS: Ninety-two patients with LUTS/BPH aged 50 years or older who were considered to be appropriate candidates for TURP were included in this study. Pressure-flow study and filling cystometry were performed to determine BOO, DUA and DO before TURP. The efficacy of TURP was determined at 3 months after surgery using the efficacy criteria for treatment of BPH assessed by the International Prostate Symptom Score, QOL index, maximum flow rate and postvoid residual urine volume. RESULTS: On preoperative urodynamics, 60%, 40% and 48% of patients showed BOO, DUA and DO, respectively. After TURP, 76% showed 'excellent' or 'good' overall efficacy, whereas only 13% fell into the 'poor/worse' category. The efficacy was higher as the preoperative degree of BOO worsened. In contrast, neither DO nor DUA influenced the outcome of TURP. However, the surgery likely provided unfavorable efficacy for patients having DO but not BOO. Only 20% of the patients who had both DO and DUA but did not have BOO achieved efficacy. CONCLUSIONS: Transurethral resection of the prostate is an effective surgical procedure for treatment of LUTS/BPH, especially for patients with BOO. DUA may not be a contraindication for TURP. The surgical indication should be circumspect for patients who do not have BOO but have DO. 相似文献
