Aims: To investigate the efficacy and safety of leflunomide, including the side‐effects, we assessed 84 rheumatoid arthritis (RA) patients who received leflunomide treatment. Methods: We analyzed the C‐reactive protein (CRP), white blood cell count (WBC), KL‐6, and visual analogue scale (VAS) scores, modified Stanford Health Assessment Questionnaire (MHAQ) score, American Rheumatism Association score (ACR20 and ACR50) within a time course after treatment with leflunomide. We treated 84 RA patients, 12 male and 72 female from 28 to 81‐years‐old, with an average age of 63.5 years. The patients were divided into three groups: a group consisting of 38 patients who received 100 mg/day of leflunomide for 3 days followed by 20 mg/day thereafter; a second group of 11 patients who received a no‐loading dose of 10 mg/day; and a third group of 35 patients who received a no loading dose of 20 mg/day. Results: The 50% decrease of CRP seen in 2 weeks was 52% of the total of 84 patients. The WBC score did not change significantly after the medication was given. The KL‐6 score did not change significantly, either. The VAS pain score improved 4 weeks later, and then further improved 8 weeks later. Therefore, RA patients using leflunomide obtained pain relief 4 weeks after commencing medication. The MHAQ score did not change significantly until 8 weeks after the patients started the medication. ACR20 was 62% and ACR50 was 38% at 8 weeks after treatment. The side‐effects of leflunomide observed in our patients were rash, respiratory infection, diarrhea, nausea, alopecia, muscle pain, headache, dizziness and general fatigue. Twenty‐three out of 84 patients experienced side‐effects (27%), and 48/84 (57%) experienced withdrawal. In our hospital, there were no patients who developed severe interstitial pneumonia (IP) or who died after taking leflunomide; however, the incidence of side‐effects of the 100 mg/day loading dose (42.1%) was 2.5 times higher than in the patients who received 20 mg/day (17.1%) of a no‐loading dose. Conclusion: Because of this, it is possible that a 100 mg/day loading dose is a relatively high risk dose in terms of causing side‐effects, especially for severely ill RA patients with a high CRP level. 相似文献

Saw palmetto extract (SPE), an extract from the ripe berries of the American dwarf palm, has been widely used as a therapeutic remedy for urinary dysfunction due to benign prostatic hyperplasia (BPH) in Europe. Numerous mechanisms of action have been proposed for SPE, including the inhibition of 5a-reductase. Today, al-adrenoceptor antagonists and muscarinic cholinoceptor antagonists are commonly used in the treatment of men with voiding symptoms secondary to BPH. The improvement of voiding symptoms in patients taking SPE may arise from its binding to pharmacologically relevant receptors in the lower urinary tract, such as al-adrenoceptors, muscarinic cholinoceptors, 1,4-dihyropyridine receptors and vanilloid receptors. Furthermore, oral administration of SPE has been shown to attenuate the up-regulation of α1-adrenoceptors in the rat prostate induced by testosterone. Thus, SPE at clinically relevant doses may exert a direct effect on the pharmacological receptors in the lower urinary tract, thereby improving urinary dysfunction in patients with BPH and an overactive bladder. SPE does not have interactions with co-administered drugs or serious adverse events in blood biochemical parameters, suggestive of its relative safety, even with long-term intake. Clinical trials (placebo-controlled and active-controlled trials) of SPE conducted in men with BPH were also reviewed. This review should contribute to the understanding of the pharmacological effects of SPE in the treatment of patients with BPH and associated lower urinary tract symptoms (LUTS). 相似文献

A 48-year-old chronic alcoholic with previous hepatitis B virus infection presented with recurrent episodes of obstructive jaundice secondary to hepatocellular carcinoma. The obstructive nature of the jaundice was confirmed by the peroral cholangioscopic findings of a friable nodular mass partially obstructing the right hepatic duct, and by relief of obstructive signs and symptoms after endoscopic sphincterotomy freed the common bile duct of “dark greenish formed materials”. 相似文献

Antiandrogen withdrawal syndrome (AWS) is a well-established phenomenon in prostate cancer. However, responses to AWS are usually of limited duration, and a complete response (CR) is extremely rare. We present two patients who exhibited a chemical CR for more than 2 years after the discontinuation of steroidal antiandrogen chlormadinone acetate use. Whether patients who respond to antiandrogen withdrawal include a group of patients with a better prognosis remains uncertain. However, considering that the usual survival period of patients with hormone-resistant prostate cancer is approximately 12 months, both of the patients reported here, who are present in excellent physical condition, exhibiting an improved quality of life, and attending their hospital as outpatients, obviously acquired a prolonged survival because of AWS. 相似文献

A 22-year-old man was diagnosed with retroperitoneal seminoma associated with Klinefelter's syndrome. The tumor was 14 x 12 cm in size and surrounded the superior mesenteric artery. He received induction chemotherapy with bleomycin, etoposide and cisplatin (BEP) followed by salvage chemotherapy with paclitaxel, ifosfamide and cisplatin (TIP). The tumor considerably decreased in size and remains as a poorly defined plaque. At the time of writing, he is being followed closely and is free from progression. 相似文献

AIM: We evaluated a prostate biopsy strategy for cancer detection using a computer simulation system with virtual needle biopsy for three-dimensional (3D) prostate models. METHODS: Two 3D prostate models with a volume of 25 cc or 50 cc were constructed from computed tomographic images of radical prostatectomy specimens. The peripheral zone (PZ) and transition zone (TZ) were arranged in the prostate models according to the anatomical information. Four thousand patterns of cancer lesions were automatically inserted into each prostate model with a proportion of 75% in PZ and 25% in TZ. Average hit rates (AHR) in prostate models were evaluated both with an increased number of biopsy cores and various angles of virtual needle biopsy. The influence of adding secondary tumors for hit rates was also evaluated. RESULTS: For both sizes, the laterally angled biopsy in 4-8 core biopsy schemes showed higher AHR than the vertical plane biopsy, while the vertical plane biopsy in 10-18 core biopsy schemes showed higher AHR than the laterally angled biopsy. A higher number of biopsy cores increased the AHR of secondary tumors. CONCLUSIONS: Our results suggest that it is important in prostate cancer detection to change the needle placement according to the number of biopsy cores and the size of the prostate. 相似文献

We present a case of aortic aneurysm in a four-year-old child complicated with tuberous sclerosis. We used the same general principles as for adult patients and successfully managed our patient. Our methods included the use of isoflurane plus epidural anaesthesia, dopamine to maintain blood pressure, and induced mild hypothermia to reduce brain metabolism and to prevent spinal cord damage during aortic cross-clamping. Intensive monitoring including EEG was beneficial to the anaesthetic management. 相似文献

Changes in splenic diameter measured by sonomicrometry in response to various adrenergic stimulants were estimated together with simultaneously measured arterial haemoglobin content (HGB) and haematocrit (HCT) in anaesthetized dogs. Splenic diameter decreased following intravenous injections (i.v.) of adrenaline, noradrenaline and phenylephrine and splenic nerve stimulation associated with increases in arterial HGB and HCT, which were significantly attenuated by prazosin i.v. After prazosin i.v., adrenaline i.v. increased splenic diameter significantly, but noradrenaline i.v. did not. Isoprenaline i.v. increased splenic diameter transiently, followed by a decrease that was abolished by prazosin i.v. During occlusion of splenic arteries and veins, adrenaline i.v. and phenylephrine i.v. did not cause any change in arterial HGB and HCT. Injection to splenic artery (i.a.) of phenylephrine induced a significant decrease in splenic diameter that was attenuated by prazosin i.a. but not by yohimbine i.a. Clonidine i.a. did not change splenic diameter. The present results indicate that splenic contraction, which is mediated through α1-adrenoceptor activation, causes a significant increase in arterial HGB and HCT. 相似文献

The expression of epidermal growth factor (EGF) and c-myc oncogene product was studied immunohistochemically in 65 benign and malignant human thyroids. Normal thyroid tissues were usually negative with each antibody. Benign and malignant neoplastic thyroid tissues demonstrated a high percentage of stained cells. However, there was no significant difference in positivity between benign and malignant neoplastic tissues. In Graves' disease 25% of the cases were positive for EGF, and 100% for c-myc product. The effect of EGF or c-myc expression on prognosis was also examined in 42 patients with papillary thyroid carcinoma. When the cases were divided into two groups with regard to their EGF staining score (highly-expressed and poorly-expressed groups), the frequency of highly-expressed tumours was significantly higher in the recurrence-positive group compared with the recurrence-free group (86% vs 57%), but there was no significant difference between the groups in respect of c-myc expression. 相似文献
