RESUMEN
AIM: We investigated the effect of acid suppression therapy on recurrent bleeding after successful endoscopic treatment of bleeding peptic ulcer. METHODS: A total of 400 patients with bleeding peptic ulcer received either intravenous infusion of famotidine (40 mg/day) (n = 207, 163 males, 44 females, mean age 61.5 years) or drip infusion of omeprazole (40 mg/day; n = 193, 134 males, 59 females, mean age 59.8 years) after successful endoscopic treatment. The fasting duration, hospital stay, volume of transfused blood, incidence of rebleeding and mortality were compared between the two groups. RESULTS: The incidence of rebleeding did not differ significantly between the famotidine group (9%) and the omeprazole group (8%). The mean hospital stay was significantly shorter in the omeprazole group (18.4 days) than in the famotidine group (21.5 days, P = 0.009). However, there was no statistically significant difference in fasting duration, volume of transfused blood or mortality. CONCLUSION: Our findings indicate that intravenous infusion of famotidine after successful endoscopic treatment is equivalent to drip infusion of omeprazole for prevention of recurrent bleeding.

BACKGROUND: The 13C urea breath test (UBT) is considered to be the most accurate way of diagnosing Helicobacter pylori infection. Our objective was to investigate the accuracy of the UBT in Japanese patients and the association of UBT values with histological findings. MATERIALS AND METHODS: A total of 169 consecutive patients were studied by endoscopy with histology, by serology with IgG antibody and test serum pepsinogen (PG), and by UBT. The association between UBT values and histological findings and the PG I / II ratio were analyzed in H. pylori-positive patients. RESULTS: Of 169 Japanese patients, 135 were H. pylori-positive on both histology and serology analysis, 27 were H. pylori-negative on both histology and serology analysis, and 7 patients showed differing results. Using a cutoff value of 2.5 per thousand, test sensitivity was 100%, while specificity was 96%. Among the 135 H. pylori-positive patients, a significant relation was observed between UBT value and H. pylori colonization density of the corpus and antrum, neutrophil activity of the antrum, atrophy, and intestinal metaplasia of the corpus in the H. pylori-positive patients. Also, UBT values correlated with the PG I /II ratio. In multivariate analysis, the PG I /II ratio was the most important factor related to UBT values (odds ration [OR], 4. 99; 95% confidence interval, 1.60-15.55). CONCLUSIONS: The UBT is an accurate method for detecting H. pylori infection in the Japanese population, which shows a high prevalence of atrophic gastritis. Values are affected by H. pylori infection and by the severity of atrophic gastritis.

BACKGROUND: Helicobacter pylori has been established as a risk factor for gastric carcinoma (GCa). Since before the discovery of H. pylori, atrophic gastritis and intestinal metaplasia have been linked to GCa, especially the intestinal-type tumor. The prevalence of H. pylori infection and atrophic gastritis increase with age. Thus, analysis of H. pylori infection in young patients with GCa could help clarify the role of this bacterium in the development of GCa. Accordingly, we investigated the relationship between H. pylori infection, GCa, and histologic gastritis in patients less than 30 years old. METHODS: Fifty GCa patients less than 30 years (mean, 26.4 years) and 100 sex- and age-matched controls (mean, 26.8 years) were examined for the presence of H. pylori infection and histologic gastritis. RESULTS: The prevalence of H. pylori infection was significantly higher in GCa patients than in controls (94% versus 40%, P < 0.01). Its prevalence was not associated with tumor location, tumor stage, or histologic type. Gastritis, atrophy, and intestinal metaplasia significantly increased the risk of GCa. By means of multiple logistic regression analysis, the odds ratio for the risk of GCa in H. pylori-positive subjects was found to be 23.5 (95% confidence interval, 6.84-80.7). CONCLUSIONS: We confirmed a strong association between H. pylori infection and GCa in young patients. Along with H. pylori infection, histologic gastritis might play an important role in the pathogenesis of GCa in these patients.

BACKGROUND: Duodenal ulcer (DU) patients exhibit raised postprandial gastrin release as compared to that in healthy controls. It is believed that serum pepsinogen I (PG I) concentration reflects the chief cell mass and that hyperpepsinogenemia I plays an important role in the pathogenesis of DU. Currently, strong evidence suggests that Helicobacter pylori (H. pylori) infection plays an important role in the pathogenesis of DU. MATERIALS AND METHODS: Subjects consisted of 15 patients with H. pylori-positive DU, 10 H. pylori-positive volunteers, and 35 H. pylori-negative volunteers. Blood samples were taken before and at 15, 30, and 60 minutes after eating the test meal, which consisted of 100 gm rice, 130 gm chicken, and 1 egg. The 1-hour integrated gastrin response (IGR) was taken as the area under the serum gastrin time curve, calculated by the trapezoid method. Serum gastrin (SG) and fasting serum PG I concentrations were measured by radioimmunoassay. RESULTS: Meal-stimulated SG response and fasting PG I concentration were significantly higher in DU patients than in H. pylori-positive and -negative volunteers. The DU patients were divided into two groups in accordance with their IGR levels as follows: hyper-IGR and normo-IGR. Serum PG I concentration was significantly higher in the hyper-IGR than in the normo-IGR group. CONCLUSIONS: The DU patients differed in some way (other than H. pylori infection) from the H. pylori-positive healthy volunteers. The fact that hyper-IGR DU patients had higher serum PG I concentrations suggests that patients in this group may be acid hypersecretors.

BACKGROUND: The combination of omeprazole, amoxicillin, and clarithromycin is a common regimen against Helicobacter pylori. Several recent studies have shown that smoking, high intragastric acidity, and the degree of histological gastritis are associated with H. pylori eradication failure. MATERIALS AND METHODS: One hundred and thirty-seven H. pylori-positive patients were treated with a 1-week regimen composed of omeprazole, 20 mg once daily; amoxicillin, 500 mg; and clarithromycin, 200 mg thrice daily. Success of the treatment was evaluated by histology and the 13C-urea breath test at least 4 weeks after completion of therapy. Data about age, gender, alcohol intake, smoking habits, and previous proton pump inhibitor intake were collected in patient interviews. We evaluated fasting gastric pH and the degree of histological gastritis before eradication of H. pylori. RESULTS: The overall eradication of H. pylori at 4 weeks was successful in 98 of 137 patients (72%). On the multivariate analysis, a low grade of inflammation in the antrum (p

BACKGROUND: This study examines endoscopic findings in the diagnosis of Helicobacter pylori (H. pylori) in the Japanese population. MATERIALS AND METHODS: The endoscopic findings (including gastric fold findings and degree of atrophy by the Kimura-Takemoto classification system), histologic severity of inflammation, and glandular atrophy were assessed according to the Sydney system in 642 patients (419 men; 223 women; mean age 43.5 years, range 13-86). H. pylori infection was evaluated by Giemsa staining and serum IgG antibodies. RESULTS: 391 of 642 patients (60.9%) were diagnosed as having endoscopic gastritis. Of the 391 patients with endoscopic gastritis, 318 (82.6%) had histologic gastritis and 310 (79.3%) had H. pylori infection. Of the 251 patients with endoscopically normal stomachs, 43 (17.1%) had histologic gastritis and 32 (12.7%) had H. pylori infection. Atrophic gastritis was the most prevalent finding (56.3%) among those with endoscopic gastritis. The prevalence of H. pylori infection in patients with atrophic gastritis (92.7%) and rugal hyperplastic gastritis (92.3%) was significantly higher than in those with other types of gastritis or with a normal stomach (12. 7%). A markedly high prevalence of H. pylori infection was found in subjects with tortuosity, hyperrugosity, and/or hyporugosity of the gastric folds. CONCLUSIONS: The accurate endoscopic assessment of gastritis according to the Sydney system along with gastric fold findings and the endoscopically identified extent of gastric atrophy are valuable indicators for determining H. pylori infection and histologic gastritis in the Japanese population.

OBJECTIVE: Several authors have reported an association between Helicobacter pylori (H. pylori) and gastric carcinoma, but the data are conflicting. Atrophic gastritis and intestinal metaplasia (IM) have also been linked to gastric carcinoma, especially the intestinal tumor type. We investigated the relationship between H. pylori infection, gastric neoplasms, and histological gastritis. METHODS: A total of 105 patients with gastric carcinoma, 36 patients with gastric adenoma, and 105 age- and sex-matched control subjects were examined for H. pylori infection and histological gastritis. H. pylori status was evaluated by Giemsa staining and IgG serology. Mucosal inflammation, atrophy, and IM were evaluated in biopsy specimens from antrum and corpus. RESULTS: H. pylori seroprevalence was higher in patients with gastric carcinoma (98 of 105, 93%) and adenoma (34 of 36, 94%) than in control subjects (82 of 105, 71%, p < 0.05). H. pylori was more prevalent in patients with noncardia (OR, 5.67; 95% CI, 2.25-14.44) than cardia (OR, 5.20; 95% CI, 0.65-41.68) tumors. Histologic types and tumor stage (early; OR, 6.60; 95% CI, 2.23-19.69, advanced; OR, 4.27; 95% CI, 1.21-15.03) showed no difference in H. pylori prevalence. Atrophy and IM scores were higher in patients with the intestinal- but not diffuse-type of carcinoma and adenoma than in H. pylori-positive control subjects. Smoking was associated with gastric carcinoma (OR, 3.05; 95% CI, 1.58-5.93) but not alcohol or coffee use, blood group A, or a family history of gastric cancer. CONCLUSIONS: Our results confirm a strong association between H. pylori and gastric carcinoma and adenoma. The intestinal-type gastric carcinoma is associated with atrophic gastritis and IM.

OBJECTIVE: Gastric cancer (GC) and adenoma (GA) are reported to be related to atrophic gastritis, in which the serum pepsinogen (PG) I level and the PGI/PGII ratio (I/II ratio) are reduced. To verify that the finding of a low PG level increases the risk for GC and GA, we investigated the correlation between low PG levels and the prevalence of GC and GA in individuals. METHODS: The 2,039 subjects (734 Japanese men, mean age 68.5 yr, and 1,305 women, mean age 66.7 yr), selected from among 10,996 local residents who underwent health check-ups based on reductions in their serum PG levels, underwent upper gastrointestinal endoscopy. RESULTS: Gastrointestinal endoscopy detected 21 GCs and 15 GAs. The prevalence of GC was higher than that in the residents without low serum PG. The percentage of early stage of GC (90%) was significantly higher than that of GC detected in unscreened residents (56.9%). The prevalence of GC in men was closely and significantly correlated with the I/II ratio (r = 0.935, p = 0.0063), whereas there was less correlation with age (r = 0.842, p = 0.0734). The prevalence of GA was also closely and significantly correlated with the I/II ratio in men (r = 0.881, p = 0.0203), but not with age (r = 0.163, p = 0.7928). In women the prevalence of GC (r = 0.744, p = 0.090) and GA (r = 0.678, p = 0.1392) did not correlate as strongly with the I/II ratio, although the highest prevalence was seen in the group with the lowest I/II ratio. CONCLUSION: Our study verified that a low I/II ratio signifies a high risk for GC and GA and that measuring serum PG levels can be used as a screening method for GC and GA.

OBJECTIVE: To evaluate the association of both Helicobacter pylori (Hp) infection and advancing age with increased prevalence of atrophic gastritis. METHODS: Two hundred and thirty-eight subjects who had no esophagitis, peptic ulcers, or malignancies in the upper gastrointestinal tract were divided into three groups according to age: group A, < 30 yr; group B, 30-49 yr; group C, > or = 50 yr. Two biopsy specimens were obtained from the lesser curvature of the antrum and two from the anterior and posterior walls of the fundus to assess the degree of gastritis and histological evidence of Hp infection. Hp infection was evaluated by Giemsa staining and serum IgG antibodies. Serum gastrin (SG) and pepsinogen (PG) were determined by radioimmunoassay. RESULTS: In all age groups, the prevalence of atrophic gastritis was significantly more common in subjects with evidence of Hp infection. In Hp-positive subjects, the prevalence of atrophic gastritis increased with advancing age. Atrophic gastritis was extremely rare, regardless of age, in Hp-uninfected patients. SG increased, and PG I and the PG I:II ratio decreased with age in Hp-positive subjects. This trend was not apparent in Hp-negative subjects. CONCLUSION: Our results suggest that Hp infection is a stronger predictor than advancing age for atrophic gastritis.

OBJECTIVES: To evaluate the degree of gastritis and the prevalence of Helicobacter pylori in Japanese patients with pernicious anemia (PA). METHODS: Histological assessment for mucosal atrophy and inflammation was performed in gastric biopsy specimens taken from 24 Japanese patients with PA and from 24 age- and sex-matched controls. The prevalence of H. pylori was evaluated by Giemsa staining and serum IgG antibodies. Serum gastrin and pepsinogens were determined by radioimmunoassay. RESULTS: All patients with PA had severe fundic atrophic gastritis, and 17 (71%) also had antral atrophic gastritis. Thirteen (54%) of 24 age- and sex-matched controls had fundic atrophic gastritis, and 15 (62%) also had antral atrophic gastritis. Mucosal inflammation was identified in the fundus of all 24 patients and in 15 (62%) controls and in the antrum of 22 (92%) patients and 16 (67%) controls. H. pylori was not detected by Giemsa staining or serum IgG antibodies to H. pylori in any patient with PA but was present in 16 (67%) controls. Serum gastrin levels were significantly higher, and serum pepsinogen I, II, and the I/II ratio were significantly lower in patients than in controls (p < 0.001). CONCLUSIONS: Our results confirm that H. pylori infection is infrequent in PA and is unlikely to be a factor in producing type A gastritis in PA.

The technique of temporal approach was originally introduced by Gillies (1927) for reduction of the zygomatic arch and zygomatic complex fracture. We reported a case of zygomatic arch fracture which was treated by temporal approach in a 36-year-old woman. She rode on a motorcycle and fell down on the ground, so she injured the right zygomatic region. Roentgenograms revealed right zygomatic arch and maxillary fracture. We performed a reconstructive operation for the right zygomatic arch fracture with temporal approach and fixated using an acrylic resin splint for 2 weeks. At 7 months after this operation, depression of the zygomatic region was improved and paralysis in the cheek and upper lip region gradually disappeared.

A case of carcinoma of the tongue treated with neoadjuvant chemotherapy has been reported. The patient was a 61-year-old man complaining of tumor and contact pain at the left margin of the tongue. The tumor was oval and elastic soft with pedicle, measuring 26 X 16 X 8 mm in size. The tumor was histopathologically diagnosed as a highly differentiated squamous cell carcinoma. The patient was treated with CDDP (75 mg/body) and PEP (5 mg/body) for 5 days. After two trials with about a 3-week interval, treatment result showed partial response. This result demonstrated that combination chemotherapy of CDDP and PEP is an effective regimen for remission neoadjuvant chemotherapy in patients with squamous cell carcinoma.

Thrombasthenia is a congenital platelet disorder characterized by the normal platelet count, prolonged bleedingtime, absence of platelet aggregation and defective clot retraction. Clinically, purpura, epistaxis, gingival bleeding and excessive bleeding after minor injuries or operations are the main manifestations. We experienced a case of a 15-year-old boy suffering from thrombasthenia required extraction of 6/6. The problems of nature of the disease and its familial character are described and the problems of management are outlined.
