In the treatment of metastatic breast cancer, trastuzumab, a recombinant monoclonal antibody against human epidermal growth factor receptor 2 (HER2), is effective when tumor cells overexpress HER2 protein. Although some cases of extramammary Paget's disease (EMPD) also express HER2 protein, no case of EMPD has been reported to be treated with trastuzumab. A 75-year-old man who suffered from EMPD of the scrotum and inguinal region underwent a local excision and lymph node dissection. Tumor cells invaded the dermis and lymph nodes. Although he was postoperatively treated with adjuvant chemotherapies, metastatic skin lesions appeared and spread over his left thigh, rapidly and widely. Tumor cells disseminated along lymph vessels in the dermis and overexpressed HER2 protein. We administered paclitaxel and trastuzumab according to a protocol for HER2-positive metastatic breast cancers. The skin metastasis dramatically decreased during the regimen and a histopathological examination showed that most of HER2-positive tumor cells diminished. Six months later, metastases were found in the central nervous system (CNS), but no other metastases were found in the skin, visceral organs or lymph nodes. Trastuzumab and paclitaxel-combination with the assessment of central nervous system lesions should be considered as an option for the treatment of HER2-positive EMPD. 相似文献

Percutaneous ethanol injection for the treatment of small hepatocellular carcinoma. Study of 95 patients 总被引:10,自引:0,他引:10
MASAAKI EBARA MASAO OHTO NOBUYUKI SUGIURA KAZUHIKO KITA MASAHARU YOSHIKAWA KUNIO OKUDA FUKUO KONDO YOICHIRO KONDO 《Journal of gastroenterology and hepatology》1990,5(6):616-626
Percutaneous ethanol injection (PEI) was applied to 120 lesions in 95 patients with hepatocellular carcinomas (HCC) smaller than 3 cm in the past 6 years. All main target tumours, in 67 patients who had been followed by sonography for more than 6 months after PEI, decreased in size; 28 tumours (41.8%) became undetectable and have remained so until now. The 1-, 2-, 3-, 4- and 5-year survival rates calculated by the Kaplan-Meier method were 93%, 81%, 65%, 52% and 28% respectively. These survival rates were better than those of patients with HCC smaller than 3 cm who did not receive anticancer treatment (P less than 0.01). The survival of patients of the Child's A or Child's B status was better than that of those with Child's C disease. Recurrence occurred in areas within the liver different from the original lesion in 34% in one year, 61% in two years and 66% in three years after PEI. PEI was then repeated in 61% of such patients. 相似文献

Class IC Antiarrhythmic Drugs, Flecainide and Pilsicainide, Produce ST Segment Elevation Simulating Inferior Myocardial Ischemia 总被引:1,自引:0,他引:1
WAKO NAKAMURA M.D. KAZUHIKO SEGAWA M.D. HIROYUKI ITO M.D. SHUGO TANAKA M.D. NOBUO YOSHIMOTO M.D. 《Journal of cardiovascular electrophysiology》1998,9(8):855-858
ST Elevation with Flecainide and Pilsicainide . Flecainide and pilsicainide, Class IC antiarrhythmic drugs with slow kinetics, were administered to a 64-year-old man experiencing ventricular tachycardia. Both drugs suppressed the arrhythmia, but caused ST segment elevation in leads II, III, and aVF. No evidence of ischemic heart disease was detected. Withdrawal of the drugs eliminated the ST change. Because these drugs frequently are used to treat tachyarrhythmias in patients who may present with chest pain, this rare ECG manifestation of Class IC drugs should he recognized to avoid misdiagnosis of acute interior myocardial infarction. 相似文献

The purpose of this study was to evaluate possible interaction of nifedipine with erythromycin or rokitamycin in the intestinal mucosa. Male beagle dogs were orally administered nifedipine (10 mg), with or without oral pre-medication with erythromycin (300 mg), and 300 mg erythromycin or rokitamycin twice a day for 3 days. The experiments were of randomized cross-over design with a two-week wash-out period between dosing regimens. Erythromycin pre-medication for 3 days resulted in a significant increase in the area under the serum nifedipine concentration-time curve (AUC), whereas the curve for one nifedipine metabolite (M-2) decreased significantly. When the effects of erythromycin on the metabolism of nifedipine were studied using dog liver microsomes it was found that erythromycin significantly inhibited formation of M-2 but not of the metabolite M-1. These results indicate that formation of M-2 from M-1 in the liver might be reduced by erythromycin premedication. To avoid possible metabolism in the gut, the dogs were then administered 8 mg nifedipine into the peritoneal cavity, with or without multiple dose pre-treatment with erythromycin for 3 days. After intraperitoneal administration of nifedipine, the maximum concentration (Cmax) of nifedipine increased significantly. After pre-administration of erythromycin the relative bioavailability of nifedipine after oral administration was increased compared with injection into the peritoneal cavity. In-vitro study using rat intestinal microsomes and the in-vivo rat intestinal loop technique also showed that pre-administration of erythromycin inhibits nifedipine metabolism in the small intestine. 相似文献

NOGAMI, A., et al. : Enhancement of J–ST-Segment Elevation by the Glucose and Insulin Test in Brugada Syndrome. The effects of glucose and insulin on J–ST-segment elevation were evaluated in seven men (mean age 45 ± 10 years) with Brugada syndrome. Six patients had been reanimated from VF and one patient had experienced syncope. The effects of intravenous (1) pilsicainide 50 mg, (2) glucose 50 g, and (3) glucose 50 g plus regular insulin 10 IU on the precordial ECG leads were examined. Pilsicainide significantly enhanced J-ST elevation in all patients and induced VF in 1 patient. A significant accentuation of the abnormal J-ST configuration was observed in all patients at a mean of 51 ± 40 minutes after glucose and insulin infusion. Changes in blood glucose and serum potassium concentration were 111 ± 158 mg/dL and −0.30 ± 0.48 mEq/L , respectively. These changes were not directly related to the ECG changes. Glucose infusion without insulin caused a subtle increase in J-ST elevation. In conclusion, the administration of glucose and insulin safely unmasked or accentuation the J–ST-segment elevation in Brugada syndrome. Blood glucose and insulin concentrations may be factors modulating the circadian or day-to-day ECG variations in this syndrome. (PACE 2003; 26[Pt. II]:332–337) 相似文献

Abstract: A cytological study of pure pancreatic juice obtained endoscopically after brushing the lesion of the pancreatic duct urns performed in 10 patients with mucin producing tumors of the pancreas. In 6 of these 10 patients, biopsies from the lesion in the pancreatic duct were also carried out endoscopically. The brushing cytology in all 6 patients with mucin producing carcinoma of the pancreas, except for the sidebranch type, showed cellular atypism and the cytological diagnoses were Class IV or Class V. The results of the brushing cytology in the patients assumed clinically benign were Class I ? Class III. Biopsy results in 4 patients with mucin producing carcinoma of the pancreas indicated that one of them had adenocarcinoma, and the other 3 had atypical hyperplasia which suggests the existence of malignancy. In the patient with adenoma, diagnosis of the biopsy specimen revealed hyperplasia only. It was concluded that cytology and biopsy of lesions in the pancreatic duct are a valuable way of assessing mucin producing tumors of the pancreas before surgery. 相似文献

A prospective follow-up study on hepatitis C virus (HCV) infection was conducted in seven haemodialysis units from April 1990 to March 1995. A total of 634 patients were undergoing maintenance haemodialysis in the seven units. Of those, 302 patients participated in the follow-up study; 179 were initially HCV antibody negative and 123 were initially positive. Nine of the 179 initially negative patients became positive for HCV antibody during the follow-up period. In accordance with the appearance of HCV antibody, indicating new infection of HCV, all nine of these patients were diagnosed with HCV viraemia. As no other routes were apparent, HCV infection in all nine patients was likely due to nosocomial transmission. Prevalence of HCV antibody at the start of follow up was significantly higher ( P < 0.001) in haemodialysis units A-C (37.9%) than in haemodialysis units D-G (17.0%). Incidence of new HCV infection was significantly higher ( P = 0.005) in the former units (2.2% per year) than in the latter (0.2% per year). Ten of the 123 patients who were initially positive for the HCV antibody exhibited a loss of reactivity during the follow-up period; of these 10 patients, nine were negative for HCV-RNA from the start of the study. In conclusion, the incidence of new HCV infection seen in patients undergoing haemodialysis suggests that their risk of acquiring HCV infection is directly related to the prevalence of HCV antibody positive patients being treated in the units. 相似文献

Abstract An 82-year-old woman with Turner syndrome and schizophrenia, and her 46-year-old daughter with schizophrenia are described. 45X/46XX chromosomal mosaicism was identified in the peripheral leukocytes of the mother, who showed several Turner dysmorphisms and cavum septi pellucidum in the brain. She had a normal reproductive life-span. The daughter resembled the mother in terms of schizophrenic symptoms, but she did not show any signs of Turner dysmorphism or chromosomal abnormality. The phenotype-karyotype relationship of Turner syndrome and the genetic relationship with psychosis are discussed. 相似文献

Pyruvate dehydrogenase complex (PDHC) deficiency is known to cause congenital lactic acidosis. The case of a 9-month-old female infant with PDHC deficiency caused by a mutation in exon 11 of the pyruvate dehydrogenase (PDH) Elα gene is described. Her facial features were as follows: frontal bossing, upslanting palpebral fissures, a short upturned nose, a long philtrum and low set ears. These anomalies are characteristic not only of a malformation syndrome or chromosomal aberration, but also of PDHC deficiency. Because PDHC deficiency requires early treatment, metabolic disorders should be kept in mind in a patient with dysmorphic features. Further, she had multiple minor anomalies including bilateral inguinal herniae, an umbilical hernia and small hands and feet, which have not been described in previous reports. 相似文献
