Colorectal Arteriovenous Malformations causing Prolonged Bleeding were Managed Successfully by Laparoscopic Low Anterior Resection with Sphincter Preservation: A Case Report / 대한소화기학회지

Gastrointestinal arteriovenous malformations (AVMs) are a rare disease. Sigmoid-anorectal AVM has only been reported in a few cases. The condition is usually detected when patients have gastrointestinal bleeding complications. The diagnosis and treatment of colorectal AVMs are still challenging. This paper presents a case of an Asian 32-year-old female patient admitted to hospital because of lower gastrointestinal bleeding lasting 17 years. The patient was diagnosed with sigmoid-rectal arteriovenous malformation and failed with other medical treatments. The damaged gastrointestinal tract was removed by a laparoscopic low anterior resection. The results were positive after a three-month follow-up; the bleeding was resolved, and the anal sphincter function was intact. Laparoscopic low anterior resection is a safe, less invasive, and effective approach for managing patients with digestive tract bleeding due to extensive colorectal AVM and preservation of the anal sphincter.

Antidiabetic and antioxidant activities of red seaweed Laurencia dendroidea

Objective: To investigate antidiabetic and antioxidant activities of the extract and fractions from Vietnamese red seaweed Laurencia dendroidea. Methods: The seaweed Laurencia dendroidea was extracted by using microwave-assisted extraction method in 80% methanol. The seaweed extract was then fractionated using different solvents (n-hexane, chloroform, ethyl acetate, butanol and water). These obtained fractions were evaluated for α -glucosidase inhibitory and antioxidant activities. Antioxidant activities were tested using DPPH, nitric oxide radical scavenging and metal chelating assays. The enzyme inhibition mode was determined using Lineweaver-Burk plot. For acidic and thermal stabilities, the ethyl acetate fraction was treated at pH 2.0 and 100 °C, respectively. The residual inhibitory activity of the fraction was calculated based on the initial inhibitory activity. For in vivo antidiabetic activity, mice were divided into four groups, including normal control, diabetic control, diabetic mice treated with ethyl acetate fraction and diabetic mice treated with gliclazide. Blood glucose level of treated mice during acute and prolonged treatments was measured. To evaluate the toxicity of the ethyl acetate fraction, the body weight changes and activities of liver function enzymes (aspartate transaminase, alanine transaminase and gamma-glutamyl transferase) were carried out. Results: The extract of Laurencia dendroidea showed strong α-glucosidase inhibitory and DPPH radical scavenging activities. Methanolic concentrations affected both α-glucosidase inhibitory and antioxidant activities. A 80% aqueous methanol was the suitable solvent for extraction of enzyme inhibitors and antioxidants. Among solvent fractions, ethyl acetate fraction had the highest inhibitory activities against α -glucosidase with a mixed type of inhibition and the strongest antioxidant activities, and was stable under acidic and thermal conditions. The ethyl acetate fraction treated diabetic mice significantly reduced blood glucose level compared with the diabetic control group (13.16 mmol/L vs. 22.75 mmol/L after 3 hours of treatment). Oral administration of ethyl acetate fraction did not exhibit toxicity at a dose of 100 mg/kg body weight as determined by body weight changes and liver biochemical parameters. Conclusions: Laurencia dendroidea could be a potential source for production of antidiabetic and antioxidative agents.

Studying the role of calcium concentration in dialysate in the rise of blood pressure during hemodialysis sessions

Background: The change of blood pressure during hemodialysis has been noted for long time. However, there were few studies on the rise of blood pressure during hemodialysis. The clinical meaning of hypertension during hemodialysis has not been understood clearly. Objective: To study the role of calcium concentration in dialysate in the rise of blood pressure during hemodialysis sessions. Subjects and method: Prospective study performed on 9 stable patients on chronic hemodialysis treated at Viet Duc Hospital including 5 female and 4 male patients. The mean age of patients was 47.6 years. The patients had period 1 of 10 weeks of treatment using dialysate 1 A (with calcium concentration 1.8 mmol/l) and then they were switched to period 2 of 10 other weeks using dialysate 3A (with calcium concentration 1.25 mmol/l). Results:The blood pressure of patients during the period 2 using 3A dialysate was better controlled during hemodialysis sessions. The response to erythropoietin treatment was similar in both periods. The serum calcium was lower after using 3A dialysate. Conclusions: Using dialysate with lower calcium concentration can be helpful for controlling the hypertension during hemodialysis sessions. The appropriate calcium concentration in dialysate needs to be selected to avoid the hypocalcaemia in chronic hemodialysis patients.

Surveillance of rats and fleas at Noi Bai international airport, 2006

Backgound: Plague disease is one of three most seriously infectious diseases (plague, yellow fever and cholera disease). In Vietnam, this condition has been obviously controlled. The number of new cases and deaths of plague disease have decreased significantly: from 439.6 patients between 1991 and 1995 to 161.2 patients between 1996 and 2000. However, the disease is still circulating in some areas in the world. Objective: To survey plague disease related factors (rats and fleas) at Noi Bai international airport. Subjects and method: A surveillance to inspect plague disease related factors (rats and fleas) was conducted at Noi Bai international airport, Ha Noi, from January/2006 to December/2006. Results and Conclusion: There were two types of rats: R. flavipectus in majority and R. norvegicus. The enrichment index of the two kinds of rats had increased in April and May. R. flavipectus disposed at flat form T1 and R. norvegicus disposed at store area. The only flea species found at the surveillance site was X.cheopis. Bacterial isolation of 236 specimens of liver and spleen, and ELISA tests of 180 blood samples were performed. All of the specimens were negative to Yersinia pestis. The study suggests that the rat populations at Noi Bai airport have not been infected with Yesinia pestis.

Adverse effects of some anti-cold preparation

Our study included 14 patients admitted to Bachmai hospital because of headache and hypertension after taking anti-cold preparations (Rhumenol Decolgen, Decolsin, and Medicoldac) from 3/2002 to 6/2002. These patients had no history of hypertension and took antiflu tablets according to instruction of manufacturers. On admission, all patients had hypertension with the maximum BP 190/120mmHg. The first-degree atrioventricular block was observed in 1 case. The adverse effects may be caused by overdose of phenylpropanolamine, a sympathomimetic agent. Our study is a warning of dangerous reality of broadly advertising, marketing and abusing drugs. The manufacturers should consider the amount of Phenylpropanolamine in anti-cold preparations to avoid the adverse effect.

Some remarks on simultaneous endometrioid carcinoma of the endometrium and ovary

Simultaneous endometrioid carcinoma of the endometrium and ovary was also called 'endometrioid systematic carcinoma'. This disease was not common with the rate of 5.2% of all endometrial carcinomas. This malignant epithelial neoplasm was presented with high differentiation (Grade 1), and it was often detected at early stages (0; 1A: 1B). Their common symptoms were abnormal metrorrhagia associating with ovarian cyst in young women having low parity. The determined diagnosis based on macroscopic and microscopic description, which could be a key significance in classification of this special lesion

Value of vaginal ultrasound in finding the endometrial cancer in the postmenopausal women with bleedin

Diagnostic curettage has for many years been the method of choice to diagnose endometrial cancer in women with postmenopausal bleeding. In fact, approximately only 10% in this group of women will be diagnosed with endometrial cancer. This study used endometrial thickness as measured by endovaginal ultrasonography as an indicator of endometrial abnormality. The histopathologic diagnosis obtained at curettage is used as the gold standard. 74 women were included in this study. Endometrial cancer was not found with the endometrium= 5 mm thick. The mean endometrial thickness in those women with endometrial cancer was 13.72+/- 8.09 mm compared with 4.3 +/- 2.3 mm in those women with benign endometrium. If the cut off limit for endometrial cancer and hyperplasia was 5 mm, the sensitivity was 100% the specificity was 71.2%, the positive predictive value was 60%, the negative predictive value was 100% and the Kappa ratio was 0.6%. If this limit had been used in this study, 70% of the curettage procedures could have been avoided.
