Abstract
OBJECTIVES The Japanese prime minister declared a state of emergency on April 7 2020 to combat the outbreak of coronavirus disease 2019 (COVID-19). This declaration was unique in the sense that it was essentially driven by the voluntary restraint of the residents. We examined the change of the infection route by investigating contact experiences with COVID-19-positive cases. STUDY DESIGN This study is a population-level questionnaire-based study using a social networking service (SNS). METHODS To assess the impact of the declaration, this study used population-level questionnaire data collected from an SNS with 121,375 respondents (between March 27 and May 5) to assess the change in transmission routes over the study period, which was measured by investigating the association between COVID-19-related symptoms and (self-reported) contact with COVID-19-infected individuals. RESULTS The results of this study show that the declaration prevented infections in the workplace, but increased domestic infections as people stayed at home. However, after April 24, workplace infections started to increase again, driven by the increase in community-acquired infections. CONCLUSIONS While careful interpretation is necessary because our data are self-reported from voluntary SNS users, these findings indicate the impact of the declaration on the change in transmission routes of COVID-19 over time in Japan.

Abstract
Post-kidney transplantation progressive multifocal leukoencephalopathy (PML) is a rare disease on which there are very few published reports on record. PML is a demyelinating disease caused by a destructive infection of the oligodendrocytes by the JC polyomavirus. No effective therapeutic protocol has been established other than measures to revive the immune function by reducing or discontinuing the administration of immunosuppressive agents. Most cases are progressive and show a poor prognosis. We herein report a case in which renal function has been maintained for 2 years following the onset of PML, which was initially diagnosed 3 years after kidney transplantation.

Abstract
BACKGROUND Granulomatous interstitial nephritis (GIN) is a rare renal disease, and its etiology remains unknown. We report recurrent GIN in renal allograft successfully treated with everolimus (EVR). CASE REPORT A 22-year-old man with GIN received a kidney from his mother. On follow-up 8 months later, his serum creatinine level was increased, from 1.3 mg/dL to 1.7 mg/dL, and he had microhematuria and proteinuria. A protocol graft biopsy at 1 year after transplantation showed epithelioid granuloma with multinucleated giant cells. He received steroid pulse therapy for recurrent GIN twice, but he developed allograft dysfunction, hematuria, and proteinuria. EVR was started in combination with maintenance immunosuppressants at 28 months after transplantation. Thereafter, the serum creatinine level decreased, from 2.1 mg/dL to 1.6 mg/dL, and microhematuria and proteinuria were stable despite reduction of steroid dose. CONCLUSIONS Maintenance immunosuppressive therapy combined with EVR may be effective for the recurrence of idiopathic GIN in renal allograft.

Abstract
Rebamipide has a broad spectrum of pharmacological actions that include suppression of neutrophil functions and stimulation of mucosal epithelial cell regeneration by increasing the expression of epithelial growth factor (EGF) and the EGF receptor. Sixteen patients with active ulcerative colitis (UC; mild in 1 patient, moderate in 11, and severe in 4) were recruited. Enemas containing 150 mg rebamipide per dosing were administered during the daytime after passage of stool, twice a day for 4 weeks. UC disease activity index (UC-DAI), endoscopic activity index (EAI), and Floren's grading (FG) of mucosal biopsy specimens were measured at entry and at 4 weeks. Five of 16 patients did not complete the study, and therefore, final efficacy assessment was done on 11 patients who completed the 4 weeks of treatment. Improvements were observed in UC-DAI (P = 0.0049), EAI (P = 0.0043), and FG (P = 0.0084). There was no serious rebamipide-related side effect in any of the 16 patients. In conclusion, rebamipide topical therapy appears to be effective for the treatment of mildly to moderately active distal UC. Further controlled studies are warranted for this promising drug.

Abstract
BACKGROUND The newer 5-ASA preparations were intended to avoid the adverse effects of SASP while maintaining its therapeutic benefits. The efficacy and safety of 5-ASA preparations have been evaluated in numerous clinical trials that have often lacked sufficient statistical power to arrive at definitive conclusions. Previously, it was found that newer 5-ASA drugs were more effective than placebo but no more effective than SASP in inducing remission in ulcerative colitis. This updated review includes more recent studies and evaluates the effectiveness, dose-responsiveness, and safety of 5-ASA preparations in terms of more precise outcome measures. OBJECTIVES To assess the efficacy, dose-responsiveness and safety of the newer release formulations of 5-aminosalicylic acid (5-ASA) compared to placebo or sulfasalazine (SASP) in the maintenance of remission in ulcerative colitis. SEARCH STRATEGY A computer-assisted literature search for relevant studies (1981-2002) was performed using MEDLINE, BIOS, the Cochrane Controlled Trials Register, the Cochrane IBD Group Specialized Trials Register, and the Science Citation Index, followed by a manual search of reference lists from previously retrieved articles, review articles, symposia proceedings, and abstracts from major gastrointestinal conferences. SELECTION CRITERIA Studies were accepted for analysis if they were prospective, randomized, double-blinded, and placebo- or SASP-controlled clinical trials of parallel design with treatment duration of at least six months. DATA COLLECTION AND ANALYSIS Based on an intention to treat principle, the primary outcome was the failure to maintain clinical or endoscopic remission. Secondary outcomes were the number of patients experiencing adverse events, the number of patients withdrawn due to adverse events, and exclusions or withdrawals after entry into the study (not due to relapse). All data were analyzed using the Peto odds ratio and corresponding 95% confidence intervals (CI). MAIN RESULTS The Peto odds ratio for the failure to maintain clinical or endoscopic remission (withdrawals and relapses) for 5-ASA versus placebo was 0.47 (95% CI, 0.36 to 0.62) with an NNT of 6. These values were also calculated for the trials in which SASP and 5-ASA were compared, revealing an odds ratio of 1.29 (95% CI, 1.05 to 1.57), with a negative NNT value (-19), suggesting a higher degree of therapeutic effectiveness for SASP. SASP and 5-ASA had similar adverse event profiles, with odds ratios of 1.16(0.62 to 2.16), and 1.31(0.86 to 1.99), respectively. The NNH values were determined to be 171 and 78 respectively. REVIEWER'S CONCLUSIONS The newer 5-ASA preparations were superior to placebo in maintenance therapy. However, the newer preparations had a statistically significant therapeutic inferiority relative to SASP. This review updates the existing review of oral 5-aminosalicylic acid for maintenance of remission in ulcerative colitis which was published in the Cochrane Library (Issue 3, 2002).

Abstract
Prostaglandins exert a protective effect on colonic mucosa in experimentally induced colitis. This study investigated the effect of enprostil, a prostaglandin E2 (PGE2) analogue, on trinitrobenzenesulphonic acid (TNBS)-induced colitis in rats. Each rat received a rectal enema containing TNBS (30 mg), followed 24 h later by intrarectal once-daily enprostil (200 microg). Enprostil-treated and control rats were killed on day 3 (enprostil group, n = 5; control, n = 6) or day 10 (enprostil group, n = 5; control, n = 5) after TNBS treatment. The area of damaged mucosa of the colon was measured relative to the total colonic area. We also determined the macroscopic score of mucosal damage, and measured PGE2, 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha) and thromboxane B2 (TXB2) concentration in portal vein blood samples. Enprostil significantly reduced both the area of damaged mucosa (including the ulcer area) and the macroscopic score after 3 days' treatment compared with control. Similarly, enprostil significantly reduced plasma concentration of PGE2, 6-keto-PGF1alpha and TXB2 during the acute phase at day 3 of treatment compared with control, but not at day 10. These results suggest that PGE2 enema may have therapeutic potential for treating patients with proctitis or left-sided colitis.

Abstract
BACKGROUND Several studies have reported that the chimeric monoclonal antibody to tumor necrosis factor (TNF)-alpha (Infliximab) is extremely valuable in the treatment of Crohn's disease. The aim of this study was to clarify the efficacy of this treatment in Japanese patients with Crohn's disease. METHODS A 12-week multicenter, open trial of Infliximab was carried out and involved 25 patients with moderate to severe Crohn's disease who were resistant to conventional treatment. Patients received a single 2-h intravenous infusion of Infliximab at a dose of 1, 3, 5 or 10 mg/kg bodyweight. Clinical evaluation of this treatment response was defined as a reduction in the index of the inflammatory bowel disease (IOIBD) and of the Crohn's disease activity index scores (CDAI), and in serum levels of C-reactive protein (CRP) at 2, 4, 8 and 12 weeks, and as an increase in serum levels of rapid turnover proteins as well as improvement of radiologic and endoscopic findings at 4 weeks. RESULTS The IOIBD score was reduced after 4 weeks in 66.7% of the group receiving 1 mg/kg Infliximab, 71.4% in the group receiving 3 mg/kg, 80.0% in the group receiving 5 mg/kg, and 85.7% in the group receiving 10 mg/kg. Improvement was better maintained over 12 weeks in the 5 and 10 mg/kg groups compared with the 1 and 3 mg/kg groups. Similar results were obtained for the CDAI scores. Serum levels of rapid turnover proteins significantly increased to within the normal ranges after infusion in all groups. Seven of the 11 (63.6%) patients evaluated showed improvement of radiologic and endoscopic findings. CONCLUSIONS A single infusion of Infliximab was effective for the treatment of Japanese patients with Crohn's disease. Serum rapid turnover proteins reflected the clinical response to antibody for TNF-alpha well.

Abstract
OBJECTIVE We assessed the roles of suprapubic cystostomy in patients with neurogenic bladder and analyzed the complications and their courses. PATIENTS AND METHODS We reviewed 118 patients with neurogenic bladder managed with suprapubic cystostomy. The original diseases were spinal cord injury in 90, degenerative disease of the central nervous system in 15, spina bifida in 6, cerebral palsy in 3, pontine bleeding in 1, Parkinson's disease in 1, brain tumor in 1, and dysgenesis of the external sphincter in 1. Fifty-six (62.2%) of spinal cord-injured patients demonstrated cervical damage. Renal function, urinary pH and white blood cell values were measured and evaluated after insertion. The stone-free rate after insertion was estimated by the Kaplan-Meier method. RESULTS Indications for cystostomy were failure of clean intermittent catheterization in 62 (52.5%) and Credé's maneuver in 2, severe urethral damage in 30 (25.4%), replacement of urethral catheter in 3, worsening of the original disease in 15 (12.7%), deterioration of the general condition in 2, mental retardation in 2, and traumatic vesical rupture in 1. Frequent complications were formation of the bladder calculi in 30 (25%) and urinary leakage through the urethra in 11 (10%). No fatal complications occurred. The stone-free rates 5 and 10 years after insertion were 77 and 64%, respectively. The urinary pH of the stone-forming group was significantly higher than that of the stone-free group. The high urinary pH group (>7.24) had a higher risk of stone formation. CONCLUSIONS Although continuous cystostomy drainage is not considered to be ideal management for bladder emptying, some patients with neurogenic bladder may benefit from this procedure.

Abstract
We have previously proposed the 'mora method' to evaluate the degree of impairment in spasmodic dysphonia (SD) in Japanese-speaking patients. With this method, impairment is judged as the proportion of impaired morae in a 25-mora sentence in a longer passage read aloud. As the mora is the phonologically isochronic unit in Japanese, the proportion of impaired morae in speech can be used to represent the temporal proportion of impaired Japanese speech. This proportional measure of impairment reflects the perceived severity of the impairment, and is a more reliable measure than a 4-point perceptual rating scale completed either by patients or by voice professionals. In this paper, we propose a 'syllable method' to characterize the severity of impairment in English-speaking SD patients. Instead of morae, the severity of SD was represented by the proportion of impaired syllables. It should be possible to characterize SD impairments more reliably and precisely with this method than using a 4-point rating scale completed by voice professionals. Ultimately, the syllable method should become a simple and effective method for evaluating the severity of SD. Furthermore, such methods can be applied to other languages, using the appropriate phonological unit (either mora or syllable).

Abstract
Partial splenic embolization is used to treat patients with liver cirrhosis accompanied by hypersplenism for improving thrombocytopenia and leukopenia. We report a case in which partial splenic embolization was used before nephrectomy because both renal cell carcinoma and liver cirrhosis were present. A 75-year-old woman visited our hospital complaining of abdominal distension. Computed tomography revealed a 5.5 cm left renal tumor. Liver cirrhosis, ascitis, splenomegaly was observed. Blood tests revealed pancytopenia; platelet count was 2.9 x 10(4)/mm3. The patient was treated by partial splenic embolization in an attempt to ensure a safe nephrectomy. After the embolization, her platelet count increased immediately to 19.2 x 10(4)/mm3, and left nephrectomy was performed successfully.

Abstract
We attempted to clarify the relationship between cyclin E to p27(Kip1), Ki-67 and clinicopathologic features in transitional cell bladder carcinoma. Immunohistochemical staining of archival tissue specimens of transitional cell bladder carcinoma obtained from 94 patients was performed by the labeled streptavidin-biotin-peroxidase method. Overexpression of cyclin E protein was observed in 38 of the 94 (40.4%) specimens, and was positively correlated with histological grade, Ki-67 LI and p27(Kip1) labeling index (LI). These data suggest that cyclin E may be associated with aggressive tumor growth, and may have a relationship with p27(Kip1) for the regulation of cell cycle progression in transitional cell bladder carcinoma.

Abstract
We examined the expression and significance of p27(Kip1) protein in 79 patients with transitional cell carcinoma of the renal pelvis and ureter. Immunohistochemical staining of archival tissue specimens was done using a labeled streptavidin-biotin-peroxidase method. There was no significant association between p27(Kip1) labeling index and histologic grade or pathologic stage. Patients with p27(Kip1) labeling indices of 27 or greater had more favorable prognoses in comparison to those with p27(kip1) labeling indices less than 27 (P<0.01). Multivariate analysis indicated that p27(Kip1) had an independent predictive prognostic value (P<0.05). The p27(Kip1) may be a novel prognostic marker for transitional cell carcinoma of the renal pelvis and ureter.

Abstract
A case of retroperitoneal liposarcoma that was removed after transarterial embolization is reported. A 62-year-old man was admitted with body weight loss and general fatigue. Computed tomography revealed an extrarenal tumor, 27 x 17 x 11 cm in size, in the left retroperitoneal space. Arteriography revealed that the hypervascular tumor was fed from the left renal artery, the left adrenal artery and the left lumber arteries (L1-L4). At first the patient underwent transarterial embolization of the left renal artery and the left lumbar arteries (L1, L3, L4). Twenty-two days later he underwent surgical excision of the tumor with combined resection of the left kidney and the descending colon. The resected tissue weighed 2,500 g. Histological examination revealed liposarcoma, pleomorphic type. His postoperative course was uneventful, and he has remained free of disease for 15 months.

Abstract
PURPOSE We retrospectively evaluated the expression and prognostic value of CD44 isoforms in transitional cell carcinoma of the renal pelvis and ureter. MATERIALS AND METHODS Using a labeled streptavidin-biotin-peroxidase method we performed immunohistochemical staining of archival tissue specimens from 62 men and 26 women with a mean age of 66.5 years who had transitional cell carcinoma of the renal pelvis and ureter. RESULTS The expression of CD44 standard (CD44s) and splice variant 6 (CD44v6) proteins was significantly decreased in relation to histological grade and pathological stage, while expression of the CD44 splice variant 3 (CD44v3) protein was decreased in relation to histological grade. The prognosis was more favorable in patients with greater versus less than 25% CD44s positive cells. CD44v3 and CD44v6 proteins had no prognostic value. Multivariate analysis indicated that only pathological stage has an independent prognostic value. CONCLUSIONS The expression of CD44 isoforms is closely associated with tumor differentiation and progression. However, it is not an independent marker and has no statistical significance greater than that of stage.

Abstract
Helicobacter pylori is an etiological agent of gastritis, gastric ulcer and gastric cancer. In order to clarify the significance of vacuolating cytotoxin (VacA) for the pathogenesis of Helicobacter pylori infection, we established and applied the sandwich bead enzyme-linked immunosorbent assay (Bead-ELISA) for quantitative determination of VacA in the culture mediums of H. pylori and other species of Helicobacter. The minimum concentration of VacA in culture medium detected by Bead-ELISA was 25 pg VacA/ml and its sensitivity was found to be quite high compared to vacuolation assay and Western blot analysis, e.g. the minimum concentrations of VacA in culture medium required for detection by vacuolation assay and Western blotting were 11 ng/ml and 38 ng/ml, respectively. All the H. pylori strains used were found to produce VacA in the culture medium by Bead ELISA, even though some strains were negative by Western blot and vacuolation assay. The results obtained by Bead-ELISA was consistent with those by PCR amplification of a 785 bp vacA fragments. A toxin immunologically similar to VacA produced by other strains of Helicobacter such as H. muridarum (ATCC49282), H. mustelae (F10) and H. felis (ATCC49179) could not be detected by Bead-ELISA as well as Western Blot.

Abstract
We describe a young Japanese woman who was diagnosed with Crohn's disease affecting the ileum, transverse colon, and rectum, as confirmed by barium studies, colonoscopy, and histopathological examination. Her father and sister also had Crohn's disease. After a 4-yr course of sulfasalazine and elemental diet therapy, she was readmitted for perianal abscess associated with the presence of pancytopenia, microhematuria with granular cast, hypocomplementemia, and high titers of autoimmune antibodies (anti-ANA and anti-dsDNA antibodies). Based on these features, a diagnosis of systemic lupus erythematosus (SLE) was made. Despite the rarity of such combination (Crohn's disease with SLE), patients with Crohn's disease who develop such clinical findings might need evaluation for SLE.

Abstract
A case of renal cell carcinoma that was discovered in a patient with typical acute pyelonephritis is reported. A 62-year-old woman admitted with fever and right flank pain, was diagnosed as having acute pyelonephritis. Intravenous urography showed a compressed renal pelvis and mild dilated calyces, suggesting the existence of a tumor. Computed tomography revealed a parapelvic tumor 6 cm in diameter and a small low-density area separated from the tumor in the renal parenchyma. Selective renal arteriography revealed a typical renal cell carcinoma lesion. The patient underwent right radical nephrectomy, and her postoperative course was uneventful. She has remained free of disease for 7 months.

Abstract
A case of adrenal hemangioma is reported. A 2.5 x 2.5 cm right adrenal tumor was discovered incidentally in a 61-year-old woman by computed tomography in October 1992. Hormonal levels were within the normal ranges, and the patient was followed for five years under a diagnosis of non-functioning adrenal tumor. The tumor enlarged slowly to 4.6 x 4.2 cm. Then the tumor was removed surgically and the pathological examination revealed adrenal cavernous hemangioma.

Abstract
A 35-year-old female presented in 1989 with hepatosplenomegaly, but no conclusive diagnosis was established. From 1992, she experienced transient episodes of facial flushing and palpitations. Osteosclerotic change was detected radiologically. Colonoscopy revealed massive polypoid lesions. Mast cells were demonstrated in bone marrow smear and imprinted preparations of colon biopsy specimens by toluidine blue staining. Plasma concentrations of histamine and soluble c-kit were elevated. She was successfully treated with interferon-alpha and prednisolone, resulting in the disappearance of histamine-related attacks and a gradual decrease in tumor size. However, the remission was interferon dose dependent. This case was considered as systemic mastocytosis with massive polypoid colon lesions and showed the importance of maintenance therapy with interferon-alpha.

Abstract
It is conceivable that the subjects who have phonatory disorders, in comparison with normal individuals, exert a greater expiratory effort when phonating loudly. Furthermore, we presume that the extent and pattern of the changes in the expiratory effort for increasing vocal intensity may vary according to the types of laryngeal lesions. To prove these hypotheses, we investigated the changes in expiratory effort for increments of the vocal intensity by measuring the expiratory lung pressure. The subjects included 10 each of normal controls, patients with Reinke's edema, and those with recurrent laryngeal nerve paralysis. For the normal controls, the increase in vocal intensity was achieved by slightly increasing the expiratory lung pressure. The patients with Reinke's edema showed a greater increase in expiratory lung pressure, as compared with the normal group. The patients with recurrent laryngeal nerve paralysis exhibited greater expiratory effort with extreme increases in airflow than normal group for louder phonation. It was concluded that the subjects who have phonatory disorders, in comparison with normal individuals, require a greater expiratory effort. This phonatory function test with an increase in voice intensity made the aerodynamic pathologic condition clearer.

Abstract
One of the shortcomings of percutaneous ethanol injection therapy (PEIT) for hepatocellular carcinoma (HCC) is that many sessions are necessary to accomplish the treatment. This may be caused by which the ultrasonography (US) image does not reflect correctly to the kinetics of injected ethanol into HCC nodule. It is considered that number of treatment sessions are able to be reduced if we just enough injected labelled ethanol under US into HCC nodule. Therefore, we tried PEIT by ethanol mixed with CO2 microbubble (CO2 ethanol). The injected CO2 ethanol was aquired as hyperechoic image without strong acoustic shadow to the end of injection. Consequently we could reduce the number of treatment sessions to almost 1 for lesions < or = 3 cm in diameter and markedly reduce total dose of injected ethanol. The detectable rate of CO2 ethanol leaked out HCC nodule was high. No serious complication occurred. There have been only 1 lesion of local recurrence and no case of intrahepatic and peritoneal dissemination for 11.5 months on average of observation after PEIT by CO2 ethanol (CO2PEIT). These findings suggest that CO2PEIT is useful method for reducing the number of treatment sessions and total dose of injected ethanol, moreover preventing complication by ethanol leakage.

Abstract
A 64-year-old man with a 5-year history of progressive systemic sclerosis (PSS) was hospitalized because of melena. Radiological and endoscopic examinations showed an ulcerative lesion with sharply demarcated and raised margins in the fornix of the stomach. Tumor markers--serum carcinoembryonic antigen (CEA, 11.3 mg/ml) and neuron-specific enolase (NSE, 38.9 ng/ml) were elevated. Histological examination of endoscopic biopsy specimens (and of necropsy specimens) showed proliferation of atypical small round cells. Immunohistological examination of these cells showed they were positive for epithelial membranous antigen (EMA), and neuron-specific enolase (NSE), but negative for UCHL1, leukocyte common antigen (LCA), anti-leukocyte B-cell (MB1), and anti-leukocyte T-cell (MT1) antigens. Based on these histological and immunohistological tests, a definite diagnosis of small cell carcinoma of the stomach with PSS was established. Our case is a rare combination of PSS and gastric small cell carcinoma. We also reviewed the literature for the association between PSS and gastric cancer in Japanese patients.

Abstract
A 69-year-old man was referred to our department with gross hematuria. Magnetic resonance imaging revealed the tumor directly invading the rectum. Biopsy of the tumor by transurethral resection demonstrated endometrioid adenocarcinoma of the prostate. Serum prostate specific antigen (PSA) level was normal. Because the tumor did not respond to hormonal therapy for a month, radical prostatectomy combined with rectal amputation was performed. Immunohistochemically, carcinoembryonic antigen was detected but PSA and prostatic acid phosphatase were not.

Abstract
In the colon of ulcerative colitis (UC) patients, apoptotic bodies have been recognized in routine histopathological preparations. To investigate the extent of the apoptosis, colonic biopsies were examined from involved and uninvolved areas of untreated active UC and from normal areas in patients with colonic polyps, utilizing various markers of apoptosis. The markers included DNA breaks detected by TUNEL, Fas (CD95/APO-1) and Fas ligand (Fas-L) localized by immunohistochemistry, electron microscopic features of apoptosis, and laddering of extracted DNA. Apoptosis marker positive cells were found mainly on the luminal epithelium of the normal colon and were present in active UC in crypts of involved and uninvolved areas of the colon, in addition to the luminal epithelium. The DNA extracted from active UC colon electrophoresed as a ladder. These findings suggest that the loss of epithelial cells in active UC occurs mainly by apoptosis in crypts of involved and adjacent uninvolved areas and that the Fas/Fas-L interaction is a mediator of the apoptosis.

Abstract
BACKGROUND The functional status of glutathione, its related enzymes, and Cu,Zn-superoxide dismutase in colonocytes isolated from rats with trinitrobenzene sulphonic acid-induced colitis, and the effect of rebamipide (a scavenger) on these antioxidants and on colitis, were studied. METHODS The rats were treated with rebamipide, killed on day 14, and compared with controls. Glutathione and enzymatic activities were spectrophotometrically estimated. The effect of rebamipide on colitis was also assessed histologically and by myeloperoxidase activity. RESULTS In controls the concentration of glutathione and the activities of glutathione S-transferase and Cu,Zn-superoxide dismutase were decreased, but that of glutathione peroxidase was increased. Rebamipide prevented the impairment of these enzymes, restored the concentration of glutathione, and attenuated (low damage scores and myeloperoxidase activity) the severity of the colitis. CONCLUSIONS These features suggest that the impairment of antioxidants is closely related to the development of the inflammatory lesions, and rebamipide has a beneficial effect on experimental colitis.

Abstract
A case of Hippocratic digital associated with secondary hypertrophic osteoarthropathy complicating Crohn's disease in a 29 year old Japanese male is reported. Hippocratic digital, or finger clubbing, complicating inflammatory bowel disease has been frequently reported in the Western hemisphere. However, its association with secondary hypertrophic osteoarthropathy has been very rarely found in that disease. In Japan, Hippocratic digital has not been described previously. With regard to the pathogenesis of Hippocratic digital and secondary hypertrophic osteoarthropathy, the theory that both entities belong to the same pathological spectrum and that megakaryocytes or platelet clumps may play the most important role, is discussed.

Abstract
Ulcerative colitis (UC) is characterized by the loss of epithelium and inflammation of lamina propria. In normal colon, epithelial cells are eliminated by apoptosis at the luminal surface. The apoptotic cells recognized by their typical morphology and the presence of DNA breaks are also accompanied by Fas and Fas-ligand. It is thought when Fas-ligand bound the Fas, the cells bearing Fas will enter a path of apoptosis. On the other hand, in inflamed areas of UC and adjacent un-inflamed areas, the apoptosis of epithelial cells are recognized anywhere along crypts. These findings suggest that unscheduled apoptosis in the UC crypts takes place and the apoptosis is mediated by a auto- or paracrine Fas/Fas-ligand interaction.

Abstract
One-hundred twelve hyperplastic polyps were analyzed. The aim was to study their malignant transformation. Among them, four hyperplastic polyps harbored adenocarcinoma; two were from our own institution (1.8%). The majority were pedunculated and located in the antrum with an average of 14.5 mm in diameter. The four polyps bore well-differentiated adenocarcinoma. Dysplasia and intestinal metaplasia were detected in two and three polyps, respectively. The cancer and dysplastic foci shared the same type of neutral and acid mucosubstances. p53 oncoprotein was positive in three cancer foci and in the dysplastic areas, and nucleolar organizer region counts were higher in the cancer foci. In conclusion, hyperplastic polyps have malignant potential. Such possibility increases in polyps larger than 14.5 mm. In our cases, the carcinoma foci may have arisen from dysplastic areas. Once the neoplastic changes occur, the cancer cells proliferate and behave as other adenocarcinomas of the stomach.

Abstract
A 58-year-old Japanese man was admitted complaining of abdominal pain. An abdominal computed tomography examination demonstrated a tumor in the head of the pancreas and multiple calcifications. A laparotomy was performed and the tumor was removed by Whipple's operation. Histologically, the neoplasm that invaded the duodenal wall and the papilla of Vater was composed of nests of malignant squamous cells with intercellular bridges and showed the formation of keratinized pearls with a small area of concurrently neoplastic glandular and squamous elements. On the basis of these features, the diagnosis of adenosquamous carcinoma of the pancreas was made. The patient died 18 months after the operation. The neoplastic behavior of this rare primary pancreatic carcinoma is similar to that of duct cell carcinoma as well as pure squamous cell carcinoma of the pancreas. As the pancreas can be the target of metastases of squamous carcinomas from other organs it is wise to be aware of this rare entity.

Abstract
We studied the role of eosinophils as effector cells in the pathophysiology of ulcerative colitis. In the active stage of this disease, the colonic mucosa exhibited infiltration of numerous eosinophils positive to the EG2 antibody, which reacts specifically with the secretory form of eosinophil cationic protein. Electron microscopic studies demonstrated that the eosinophils had specific granules in various stages of degranulation. Hence, it is strongly suggested that the eosinophils infiltrating the inflamed mucosa are activated and may induce tissue damage during the degranulation and release of this cationic protein. Changes in the levels of serum eosinophil cationic protein in 14 patients who remained for in long-term remission were studied. Four of these patients showed persistently high concentrations of eosinophil cationic protein (equal to or greater than 30 micrograms/l) and persistently high percentage (mean, 30.2%) of hypodense eosinophils (specific gravity < 1.082) in the peripheral blood. Such findings were associated with mild active disease at colonoscopy. These features suggest that the activation of eosinophils is one of the factors that contribute to the chronic inflammation in ulcerative colitis.

Abstract
A rare case of adult T-cell leukemia (ATL) in which multiple lymphomatous polyposis (MLP) was revealed throughout the entire gastrointestinal tract is reported here. The polypectomy specimens taken from the rectum revealed infiltration of neoplastic T-cells, the integration of HTLV-1 proviral DNA, and increased CD4 (OKT4) and CD25 (IL-2R) cells. The analysis of surface markers of the lymphocytes from polypoid lesions may be useful for elucidating cell tropism and homing properties in the gastrointestinal tract. Although MLP has always been associated with B-cell lymphoma in the Western world, it is important for clinicians and pathologists to be aware that MLP may be caused by the infiltration of ATL cells.
