The case of a 64‐year‐old patient with pica and severe mental retardation who was admitted to our hospital for treatment of recurrent cholecystitis is reported. Abdominal ultrasound showed sludge in the gallbladder, but no stones. Abdominal CT revealed a foreign body in the duodenum resembling a suction cup of the type commonly used in kitchens and bathrooms. The object could not be removed because it was deeply embedded in the hypertrophic intestinal mucosa. A nasogastric tube was inserted for feeding, since the object impeded the passage of solid foods. The patient's fever and abdominal pain subsequently resolved, and laboratory data improved. The indwelling feeding tube prevented recurrence of cholecystitis. Since pica is common not only in patients with mental retardation but also in dementia patients, the present case may also relate to the treatment of acute abdominal conditions in dementia patients. 相似文献

Fas-associated phosphatase-1 promotes Fas-mediated apoptosis in human colon cancer cells: Novel function of FAP-1 总被引:2,自引:0,他引:2
TAKAKO MIYAZAKI YOSHINARI ATARASHI SATOSHI YASUMURA ISAO MINATOYA KOHEI OGAWA MASAYA IWAMOTO MASAMI MINEMURA YUKIHIRO SHIMIZU TAKA-AKI SATO AKIHARU WATANABE TOSHIRO SUGIYAMA 《Journal of gastroenterology and hepatology》2006,21(1):84-91
Background and Aim: Fas‐associated phosphatase‐1 (FAP‐1) has been thought as an inhibitor in Fas‐mediated apoptosis. Here, we investigated the role of FAP‐1 in Fas‐mediated apoptosis of human colon cancer cells. Method: The viability of four colon cancer cell lines treated with agonistic anti‐Fas antibody was determined using WST‐1 assay and cell death detection ELISA. pRc/CMV‐FAP‐1 was transfected to a FAP‐1‐negative, Fas‐resistant colon cancer cell line SW480 by lipofection and the clones expressing FAP‐1 protein were selected by limiting dilution. In the clones, expression of 550 genes was analyzed by cDNA microarrays. Protein expression of FAP‐1 and molecules related to apoptosis was examined by western blot. Results: We obtained two FAP‐1 overexpressed clones which were much more susceptible to Fas‐mediated apoptosis than control cells. In the clones, caspase 8 and caspase 3 were fully activated by agonistic anti‐Fas antibody treatment. Bcl‐2 family proteins were not related to the high susceptibility of these clones, because caspase 9 was not activated. Transfection of FAP‐1 did not suppress the survival actions of insulin‐like growth factor (IGF‐1) which enhanced survival signal through Akt phosphorylation. Upregulation in 21 genes and downregulation in 29 genes was revealed by cDNA arrays. We confirmed protein expression of p21 and phosphorylated p21 were much more enhanced in the clones than in control cells. Conclusions: Overexpression of FAP‐1 enhanced susceptibility to Fas‐mediated apoptosis in SW480 and upregulation of p21 may contribute to this phenomenon. Our results indicate a novel function of FAP‐1 in Fas‐mediated apoptosis of human colon cancer cells. 相似文献

Abstract To examine the validity of ICD-10 subcategories for obsessive-compulsive disorder (OCD), the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was applied to 53 OCD patients. The ratios of Y-BOCS compulsions subscore to obsessions subscore were calculated. The group with ratios around one consisted of patients diagnosed in three subcategories (F42.0, F42.1 and F42.2). This suggests that subjective subcategorization such as ICD-10 may be inadequate to differentiate between predominantly obsessive and compulsive patients compared with differentiation by quantitative assessment such as the Y-BOCS ratio. Thus, in selecting the appropriate therapeutic methods, we emphasize the usefulness of quantitative assessment in clinical settings. 相似文献

To assess the biochemical and histological characteristics of hepatitis G virus (HGV) infection, we examined four patients who were infected with HGV only (HGV group), and compared them with 16 patients infected with both HGV and hepatitis C virus (HCV; HGV + HCV group) and 18 patients infected with HCV only (HCV group). Biochemical examination showed a significantly low level of serum alanine aminotransferase (ALT) in the HGV group, and that the gamma-glutamyl transpeptidase (γ-GTP)/ALT ratio in the same group was significantly higher than in the other two groups. Although all three patient groups had a similar degree of liver fibrosis, both the degree of periportal inflammation and total histological activity index were significantly lower in the HGV group than in the other two groups. Fibrous enlargement of the portal tract without lymphoid infiltration and thin fibrous septa was characteristically observed in the HGV group. No significant difference was found between the HGV + HCV group and HCV group. Our results suggest that biochemical and histological changes in HGV infection are very mild and quite different from those of HCV infection. 相似文献

To virologically assess the efficacy of interferon therapy in chronic hepatitis C, either 5 or 10 MU/day natural interferon-α (IFNα) was administered to 57 patients with chronic hepatitis C for 38 weeks. A complete and sustained response (CR-SR), as evidenced by the absence of serum hepatitis C virus (HCV)-RNA during the administration period and at 6 months after the final administration of IFNα and a normal GPT level at 6 months after final administration, occurred in 42.6% (23/54) of subjects. Liver tissue was histologically evaluated using the histological activity index (HAI) score before and after the administration period. In CR-SR cases, significant improvements (P <0.01) occurred in periportal necrosis, intralobular necrosis, portal inflammation and total score. A comparison, by HCV genotypes, revealed that CR-SR occurred in 60% (9/15) of subjects with type 2a and 30.3% (10/33) of subjects with type Ib. A comparison by virus concentration revealed that CR-SR occurred in 71.4% (15/21) of those subjects having a virus concentration of < 105 copies/mL, but in only 24.2% (8/33) of those having a virus concentration of > 105 copies/mL. Analysis by a multiple logistic model revealed a strong correlation between the therapeutic effect of interferon therapy and the pre-administration virus concentration (P=0.0061) and genotype (P=0.0015). These results suggest that the preadministration virus concentration and genotype are both key factors affecting the therapeutic effect of interferon therapy in chronic hepatitis C and that the therapeutic effect of interferon is satisfactorily high, irrespective of virus concentration, in subjects with type 2a HCV, but varies depending on virus concentration in subjects with type 1b. 相似文献

AIM: The objective of the present study was to characterize the clinicopathological features of histologically defined papillary renal cell carcinoma (RCC). METHODS: The present study included a total of 35 patients who were treated by radical surgery and subsequently diagnosed as having papillary RCC between April 1995 and June 2004. Clinicopathological data of these patients were retrospectively reviewed according to the previously reported classification system (Mod. Pathol. 1997; 10: 537-44). RESULTS: Of these 35 patients, 23 (65.7%) and 12 (34.3%) were diagnosed as type 1 and type 2 papillary RCC, respectively. Despite the lack of significant differences in clinical parameters between these two groups, including age, gender, clinical stage and metastasis, the incidence of symptomatic disease in patients with type 2 papillary RCC was significantly higher than that in those with type 1 papillary RCC. Pathological examinations demonstrated that there were no significant differences between these two groups in pathological stage, tumor grade or vascular invasion. Furthermore, there was no significant difference between these two groups in overall or recurrence-free survival. CONCLUSIONS: Although the present study included a small number of patients with short follow-up period, the clinicopathological features including prognoses were almost similar between patients with type 1 and type 2 papillary RCC; therefore, careful postoperative follow-up should be considered for patients with papillary RCC irrespective of morphological subtype. 相似文献

BACKGROUND: The objective of the present study was to analyze the pathological findings of radical prostatectomy specimens diagnosed on single core positive prostate biopsy in eight systematic transrectal ultrasonography (TRUS)-guided biopsies with a Gleason score = 4. METHODS: Between January 1993 and March 2001, 975 patients underwent TRUS-guided prostate biopsy, and 32 patients were diagnosed as having prostate cancer based only on one positive core with a Gleason score = 4. In this study, 14 of the 32 patients who underwent radical prostatectomy without any neoadjuvant therapies were enrolled, and the pathological findings of their radical prostatectomy specimens were evaluated. RESULTS: The clinical stage of the 14 patients was T1c in 10 and T2 in four. Cancer was detected in the prostate apex in seven patients, the middle in two, the base of the peripheral zone (PZ) in three, the lateral horn of the PZ in one and the transitional zone (TZ) one. Pathological stage of the 14 patients was pT2a in four, pT2b in six, pT3a in three and pT3b one. Gleason score of the radical prostatectomy specimens in 11 patients was also = 4. Of the 10 patients diagnosed with cT1c, extraprostatic disease was found in only one radical prostatectomy specimen. All three patients whose cancer was detected from the base of the PZ showed pT3 disease. During the median follow-up period of 47.5 months, all patients were alive with no evidence of disease. CONCLUSION: The prognosis of patients who were diagnosed with one core positive prostate biopsy with a Gleason score = 4 is generally favorable; however, advanced disease tended to be observed in patients who were diagnosed with cT2a and/or whose cancer was detected from the base of PZ. 相似文献

BACKGROUND: The objective of this study was to assess the usefulness of combined systematic prostate biopsy with the serum level of cathepsin D, which has recently been shown to be a useful marker for prostate cancer, to predict the disease extension. METHODS: Seventy-two patients with clinically organ-confined disease who underwent radical prostatectomy were evaluated for serum prostate-specific antigen (PSA) and cathepsin D levels, systematic biopsy, and pathological stage. RESULTS: The incidence of extraprostatic disease in patients with more than half the biopsy cores positive or > or = 15 ng/mL cathepsin D was significantly higher than that in patients with less than half the biopsy cores positive or < 15 ng/mL cathepsin D, respectively; whereas cancer in bilateral lobes or > or = 10 ng/mL PSA could not be used as a predictor of extraprostatic disease. Furthermore, in patients with more than half the biopsy cores positive and > or = 15 ng/mL cathepsin D or those with more than half the biopsy cores positive and > or = 10 ng/mL PSA, extraprostatic disease was significantly more common than in those with less than half the biopsy cores positive and < 15 ng/mL cathepsin D or those with less than half the biopsy cores positive and < 10 ng/mL PSA, respectively. Furthermore, the prediction of the incidence of extraprostatic disease using these three variables was significantly more accurate than using two of the variables (percentage positive biopsy cores plus serum cathepsin D or PSA). CONCLUSION: Systematic biopsy together with serum cathepsin D and/or PSA was a useful predictor of the extent of prostate cancer. Patients with more than half the biopsy cores positive, > or = 15 ng/mL cathepsin D and/or > or = 10 ng/mL PSA could avoid prostatectomy because there is a significantly high probability that they already have extraprostatic disease. 相似文献
