Endoscopic band ligation for postpolypectomy gastric bleeding

We report a case of a patient in whom endoscopic band ligation was achieved for postpolypectomy gastric bleeding. A 76‐year‐old man visited our hospital because of anemia. Endoscopy revealed a gastric polyp, approximately 12 mm in diameter, on the lesser curvature in the distal gastric body. The polyp was considered to be the source of chronic anemia and was therefore removed by using standard careful snare‐cautery polypectomy technique. Four days later, follow‐up endoscopy was performed to evaluate the postpolypectomy site, and an active bleeding postpolypectomy ulcer was identified. Initial attempts to achieve hemostasis with ethanol injection were unsuccessful. Immediate hemostasis was obtained with a subsequent endoscopic band ligation device. There has been no recurrent bleeding. Endoscopic band ligation might be a good treatment modality for the treatment of a postpolypectomy gastric bleeding lesion.     

A study of the hemoglobin levels in breast-fed infants in one village of Okinawa prefecture

We investigated the prevalence of anemia and the hemoglobin levels in breast-fed infants. Three hundred and fifty-six healthy children with different feeding methods were studied longitudinally. The results showed that the prevalence of anemia was higher and the hemoglobin levels were lower in breast-fed infants compared with those in partially breast-fed or formula-fed infants at late infancy.     

Antibodies to hepatitis C virus and elevated transaminase levels in a town of hyperendemicity in Iwate, Japan

In an annual survey for liver function tests in persons aged > xs35 years in Iwate Prefecture, Japan, a town was identified where high levels of alanine aminotransferase abounded. Of 5152 inhabitants aged > 35 years in this town, antibodies to hepatitis C virus (HCV) determined by enzyme-linked immunosorbent assay with HCV core peptides were detected in 798 (15.5%) people, hepatitis B surface antigen was detected in 47 (0.9%) people and antibodies to hepatitis B surface antigen and/or hepatitis B core antigen unaccompanied by surface antigenaemia were detected in 1748 (33.9%) people. Antibodies to HCV core peptides correlated closely with the antibodies detected by passive haem-agglutination with recombinant HCV proteins of the second generation. Antibodies to HCV core peptides were particularly common in one of the nine districts of the town (district 8), where 276 (45.3%) of 609 inhabitants tested positive; there were no differences in the frequency of serological markers of hepatitis B virus (HEV) infection among residents in the nine districts. Of the 798 individuals with antibodies to HCV core peptides, 257 (32.2%) were found to have elevated transaminase levels. A history of transfusion was associated with a high frequency of antibodies to HCV core peptides, except in district 8 where such antibodies were equally frequent in residents irrespective of transfusions. These results indicate an epidemiology of HCV distinct from that of HBV in this town and a very local spread of HCV, as well as a high frequency of hepatic injuries in individuals with antibodies to HCV.     

Inhibitory Effect of Laser Irradiation on Dermal Syngeneic Tumor Growth in Mice

Mice (C57BL/6) with established intradermal tumors (melanomaB-16 or glioma 203G1) and inbred Swiss mice (SWM/Ms) with establishedintradermal tumors (3-methylcholanthrene-induced sarcoma) weretreated by either surgical excision or laser irradiation. Laserirradiation is effective in preventing the growth of dermalmelanoma, and laser therapy may be more efficacious than surgicaltherapy for induction of a reaction against melanoma in mice. The results also suggest that determination of a suitable laserwavelength may be required to obtain a good therapeutic effecton each tumor.     

Incidence of Haemophilus influenzae in the throats of healthy infants with different feeding methods

BACKGROUND: Haemophilus influenzae is the major cause of otitis media and lower respiratory tract infection in childhood. In the presence of human milk, which contains numerous host defense factors, Haemophilus influenzae may be inhibited in attaching to and colonizing pharyngeal cells. We investigated the incidence of H. influenzae in the throats of 162 healthy infants with different feeding methods: 70 breast-fed, 49 mixed-fed and 43 formula-fed infants. METHODS AND RESULTS: Haemophilus influenzae was identified using standard microbiological procedures and the API NH system. The incidence of H. influenzae in breast-fed infants, mixed-fed infants and formula-fed infants was 0, 0 and 7.0% respectively. CONCLUSION: The results suggest that the colonization of H. influenzae in the throat was inhibited by the presence of breast milk.     

Levels of serum ferritin and total body iron among infants with different feeding regimens

The levels of serum ferritin and total body iron of healthy infants were analyzed to evaluate iron status among infants with different feeding regimens. The results showed that the levels of serum ferritin and total body iron were lower in breast-fed infants than in partially breast-fed or formula-fed infants at late infancy and 18 months of age.     

Oxalate-degrading Providencia rettgeri isolated from human stools

BACKGROUND: Oxalate-degrading bacteria are thought to metabolize intestinal oxalate and thus decrease the urinary excretion of oxalate by reducing its intestinal absorption. METHODS: We have isolated several novel oxalate-degrading bacteria from human stools. Oxalate degrading bacteria were investigated to characterize their protein profiles with antibodies against oxalyl-coenzyme A decarboxylase (65 kDa) and formyl-coenzyme A transferase (48 kDa) purified from Oxalobacter formigenes. RESULTS: One of these isolates was identified as Providencia rettgeri, which showed two proteins (65 kDa and 48 kDa) on sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) that were not found in non-oxalate-degrading P. rettgeri. Antibodies reacted with the 65 and 48 kDa proteins from the P. rettgeri strain on Western blotting. An Oxalobacter formigenes formyl-coenzyme A transferase gene probe reacted with chromosomal DNA from P. rettgeri on Southern blotting under high stringency conditions, while an Oxalobacter formigenes oxalyl-coenzyme A decarboxylase gene probe did not react under the same conditions. CONCLUSIONS: The mechamism of oxalate degradation by P. rettgeri appears to be similar to that of Oxalobacter formigenes. This is the first report of a facultative oxalate-degrading organism that is one of the Enterobacteriaceae.     

A study of the iron requirement in infants,using changes in total body iron determined by hemoglobin,serum ferritin and bodyweight

The amount of iron absorption in healthy breast-fed infants was estimated in order to assess the iron requirement. This was carried out by monitoring changes in total body iron (TBI). Hemoglobin and serum ferritin were measure to calculate hemoglobin iron, body storage iron and TB1 at the ages of 4–5 months and 10–11 months. The amount of iron absorption was ∼ 0.4 mg/day, calculated as the sum of TBI increment and physiological iron loss. From this study, the dietary iron requirement for the weaning period was estimated as 4 mg/day.     

Urolithiasis in Okinawa, Japan: A relatively high prevalence of uric acid stones

AIM: The aim of the present study was to investigate the composition of urinary tract stones in patients from Okinawa, the most southern island group of Japan. METHODS: The study was conducted by 12 hospitals in Okinawa. A total of 1816 urinary tract calculi were obtained from 1816 patients (1323 males; 493 females). The patients had a mean age of 53 +/- 15.3 years (mean +/- SD). The calculi were examined to determine their chemical composition. Stone samples were analyzed by computed infrared spectrophotometer. RESULTS: Pure stones comprised 58.4% of the total, with calcium oxalate stones accounting for 40% (21% monohydrate [whewellite]; 6.6% dihydrate [weddellite]; and 12.4% combined monohydrate and dihydrate stones), uric acid/urate stones for 9.6%, calcium phosphate stones for 5.1%, and struvite stones for 3.7%. The other 41.6% of the stones consisted of calcium oxalate mixed with other components. The male-to-female ratio was 2.7:1. CONCLUSION: In our series, calcium oxalate stones accounted for 81.6% of the urinary tract calculi, while uric acid/urate stones accounted for 15.8%. Uric acid stones, predominantly the anhydrous and/or dihydrate forms, showed a relatively high prevalence. Calcium oxalate stones, predominantly in the form of whewellite, showed a high prevalence among pure calculi; while the predominant combinations among mixed calculi were weddellite + calcium phosphate and whewellite + uric acid/urate.
