Detection of hepatocellular carcinoma after interferon therapy for chronic hepatitis C: Clinical study of 26 cases 总被引:1,自引:0,他引:1
NOBUYUKI SUGIURA YUZOH SAKAI MASAAKI EBARA HIROYUKI FUKUDA MASAHARU YOSHIKAWA HIROMITSU SAISHO MASAO OHTO FUKUO KONDO 《Journal of gastroenterology and hepatology》1996,11(6):535-539
The clinical findings in 26 patients in whom hepatocellular carcinoma (HCC) was detected after the start of interferon (IFN) therapy for chronic hepatitis C were analysed. Histological study before IFN therapy showed that 34.6% of patients were categorized as stage 3 (septal fibrosis with architectural distortion; the 0–4 scale) and 80.8% demonstrated at least some evidence of septal fibrosis or more advanced features. The AFP levels examined before IFN therapy were more than 20 ng/mL in 13 patients (84.6% of those studied). One of 26 patients had a complete response to IFN therapy, while six of 26 patients had only a partial response. HCC was detected within 1 year after the start of IFN therapy in 76.9% of patients. Thus, the possibility of the early occurrence of HCC or its existence at the time of therapy should be seriously considered when IFN therapy is contemplated. Patients with stage 3 or 3–4 histology may already have a small undetectable HCC before IFN therapy. Thus, for this reason, every patient treated with IFN should be examined at short regular intervals for the development of HCC during and after IFN therapy. 相似文献

Incidence and growth pattern of simple cysts of the kidney in patients with asymptomatic microscopic hematuria 总被引:1,自引:0,他引:1

BACKGROUND: We examined the incidence and natural history of simple renal cysts found by ultrasonography (US) in patients referred for asymptomatic microscopic hematuria. METHODS: Among the 906 patients aged 18-78 years, 743 patients who had undergone US were included in the present study. The natural history of simple renal cysts was investigated in 55 patients who underwent periodical US examinations for more than 3 years. RESULTS: The incidence of simple renal cysts was 4.3% for ages 29 years or younger, 15.3% for ages 30-39, 21.8% for ages 40-49, 23.3% for ages 50-59 and 32.6% for ages 60 years or older; thus the incidence increased in older age groups (P = 0.0005 for men, P = 0.0020 for women). Men tended to have a higher incidence than women. The degree of hematuria did not influence the incidence of renal cysts (P = 0.9044). The annual growth rate of the mean maximum diameter was 4.2% during a 3-year follow-up period in 55 patients and 5.1% during a 6-year follow-up in 31 patients. CONCLUSION: Since the diameter of a renal cyst may increase by 5% annually, the diameter of the cyst may increase by 1.6 times in 10 years. The scheduling of follow-up examinations depends on the size at the time of disclosure, the effects on calyceal systems, or the suspicion of a concurrent malignant disease. However, the most simple renal cysts may be followed-up at an interval of more than 10 years, once a diagnosis has been established. 相似文献

A case of "sclerosing hemangionia" (pneumocytoma) of the lungwith lymph node metastasis is reported. A 22-year-old Japaneseman was found to have a well-defined round lesion in the rightlung (S7), which increased in size slightly during a 2-yearfollow-up period. He underwent right lower lobectomy with a preoperative diagnosisof a benign lung tumor. The pulmonary tumor revealed histologicalfeatures characteristic of "sclerosing hemangioma" of the lung,in addition to which there were many large polygonal foamy cells,forming tubular or papillary structures. These cells were foundby electron microscopy to contain numerous cytoplasmic lamellarbodies and showed a positive reaction with anti-surfactant apoproteinantibody immunohistochemically. Therefore, they were consideredto be cells differentiating toward type II pneumocytes. Reviewof 21 typical "sclerosing hemangionia" disclosed a few or somesuch foamy cells in 10 cases. A single hilar lymph node wasthe site of microscopic metastases, which consisted of "largeclear foamy cells" and smaller polygonal or round cells withslightly eosinophilic cytoplasm, both of which were componentsof the pulmonary "sclerosing hemangioma" This case supportsthe theory that "sclerosing hemangioma" is a neoplasm of typeII pneumocyte lineage. Although it is said to be benign, rarecases apparently show metastatic potential. 相似文献

THE IMPACT OF DIABETES MELLITUS ON THE PROGNOSIS OF ALCOHOLICS 总被引:1,自引:0,他引:1

In this study, the mortality of clinically treated Japanesealcoholics with diabetes mellitus was analysed. Fifty-one diabeticalcoholics without liver cirrhosis (DM), 23 diabetic and cirrhoticalcoholics (DM LC), 44 cirrhotic alcoholics without diabetes(LC), and 354 alcoholics without either complication (AL) admittedto the National Institute on Alcoholism in 1985 were studied.Thirty-seven diabetics required insulin treatment, and 12 oralhypoglycemic agents. The 4.4-year survival and drinking statusafter discharge were studied in 1990. Stepwise logistic regressionanalysis showed that the estimated odds for death increased8.10, 4.38, 3.70, and 3.27 times for the subjects with the alcoholmisuse after discharge, DM, DM LC, and LC, respectively. The4.4-year survival rate of alcoholics who continued misusingalcohol was much lower in DM (26%, P < 0.0005) and LC (35%,P < 0.0001) than in AL (73%). The survival rate of thosewho stopped misusing alcohol was significantly higher in DM(90%, P < 0.0001), LC (88%, P < 0.0001) and AL (94%, P< 0.0005) than those who continued misusing alcohol. Therewas no significant difference in the survival rate between thealcoholics with DM LC who continued misusing alcohol (50%) andthose who stopped misusing alcohol (73%). In the dead patients,56% of DM died unexpectedly or suddenly, whereas 71% of LC diedof liver failure after hospitalization. These results suggestthat diabetic alcoholics should be intensively educated forabstinence. 相似文献

The metallic stent has become the most common device to reduce acute occlusion and late restenosis after balloon angioplasty, but the long-term effects of metallic stents in human coronary arteries are still unknown. To overcome several problems of conventional stenting, there have been many attempts to manufacture stents made of biodegradable materials. Although some studies have noted various degrees of inflammatory responses after biodegradable stent implantation, stents made of poly-1-lactic acid (PLLA) showed high biocompatibility with minimal inflammatory response and neointimal formation in porcine coronary arteries. A clinical study of PLLA self-expanding stent implantation is underway in Japan. The initial and 6-month results are favorable and suggest the feasibility, safety, and efficacy of the PLLA biodegradable stent in humans. However, long-term follow-up with larger numbers of patients will be required to validate the long-term efficacy of PLLA stents. 相似文献

In this review article, in order to explore the mechanisms underlying the hallucinations/delusions of schizophrenia, we discuss the contribution of the following four questions: (i) can an understanding of dreams contribute to our understanding of the genesis of halluciations and/or delusions; (ii) are the mechanisms underlying psychotropic drug‐induced psychoses the same as those underlying the hallucinations and/or delusions in schizophrenia; (iii) does disturbed consciousness contribute to the manifestation of psychotic features; and (iv) are the psychoses caused by organic brain disorders any different to the hallucinations and/or delusions seen in schizophrenia? We conclude that there is a strong association between drug‐induced hallucinations or hallucinations associated with organic brain disorders and simple hallucinosis or fluctuations in arousal level. Because intermediate configurations and/or cross‐staining phenomena exist for hallucinations and delusions, especially in schizophrenic disorders, it is difficult to isolate the hallucinations and to recognize them as being abnormal experiences. 相似文献

Twenty-four human legs were dissected macroscopically to study the morphological details of the accessory deep peroneal nerve. This nerve arose from the superficial peroneal nerve and descended in the lateral compartment of the leg, deep to peroneus longus along the posterior border of peroneus brevis. Approaching the ankle joint, this nerve passed through the peroneal tunnels to wind around the lateral malleolus; it then crossed beneath the peroneus brevis tendon anteriorly to reach the dorsum of the foot. The accessory deep peroneal nerve was found in every case examined and constantly gave off muscular branches to peroneus brevis and sensory branches to the ankle region. In addition, this nerve occasionally had muscular branches to peroneus longus and extensor digitorum brevis, and sensory branches to the fibula and the foot. The anomalous muscles around the lateral malleolus were also innervated by this nerve. Neither cutaneous branches nor communicating branches with other nerves were found. The present study reveals that the accessory deep peroneal nerve is consistently present and possesses a proper motor and sensory distribution in the lateral region of the leg and ankle. It is not an anomalous nerve as has previously been suggested. 相似文献

Serum levels of CA15-3, a mammary tumor associated antigen recognizedby two different murine monoclonal antibodies (115D8 and DF3),were investigated in patients with mammary carcinoma and otherbenign or malignant diseases. The reference value of the serumCA15-3 level was obtained as 24 units/ml at the 99% confidencelimit among healthy individuals (n = 462). Elevation of serumCA15-3 levels was observed in 24.3% of overall patients withmammary carcinoma. Serum CA15-3 levels in breast cancer patientscorrelated with the clinical stage; higher percentages of positivitywere observed in those with advanced breast cancer (stage IV,64.7%, recurrent, 52.4% and metastatic, 70.3%). Furthermore,elevated serum CA15-3 levels in breast cancer patients respondedwell to the effect of therapy. Although the serum CA15-3 testgave percentages of positivity of breast cancer similar to thosefound by the serum CEA test, the serum CA15-3 test revealedlower percentages of posi-tivity than the serum CEA test amongpatients with benign breast lesions, liver cirrhosis or othercarcinomas. These results suggest that the serum CA15-3 antigenlevel provides a very useful marker for diagnosis and clinicalmonitoring of patients with breast cancer. 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

Clonal and non-clonal karyotypically abnormal cells in haemophagocytic lymphohistiocytosis 总被引:1,自引:0,他引:1
YASUHIKO KANEKO NOBUO MASEKI MASAHARU SAKURAI MASARU IDO YUKIKO TSDNEMATSU SHUKI MIZUTANI TATSUYA HATTORI HIROYUKI SHIMIZU HARUHIKO EGUCHI TOSHIAKI OKA MUNENORI MIYAKE YASUO HORIKOSHI TAIZAN SUCHI 《British journal of haematology》1995,90(1):48-55
We studied chromosomes in bone marrow (BM) or peripheral blood cells of nine patients with haemophagocytic lymphohistiocytosis (HLH); three of them had a family history of HLH and four others underwent concurrent Epstein-Barr virus (EBV) infection. In addition to a large population of normal mitotic cells, karyotypically abnormal clonal cells were found in two patients, abnormal clonal cells and a nonclonal (single) abnormal cell in one, and nonclonal abnormal cells in three. All the six patients with chromosome abnormalities died of progressive disease; one of them also had EBV infection and EBV-associated clonal proliferation. Two of three patients with EBV infection and only normal mitotic cells in BM completely recovered from the disease.
Although HLH did not show histological and/or haema-tological evidence of a neoplastic disease, clonal chromosome abnormalities and the fatal clinical outcome found in some of the patients suggest that the disease may be heterogenous and include malignancy. HLH patients with karyotypically abnormal clonal cells in BM should warrant more intensive chemotherapy than that presently being applied to them and should be considered as candidates for BM transplantation. 相似文献
