Nehal M El-Koofy, Ghada M Anwar, Mona S El-Raziky, Ahmad M El-Hennawy, Fatma M El-Mougy, Hanaa M El-Karaksy, Fetouh M Hassanin, Heba M Helmy
January-February 2012, 18(1):44-49
DOI:10.4103/1319-3767.91738  PMID:22249092
Background/Aim: To study the prevalence of metabolic syndrome (MS), insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD) in overweight/obese children with clinical hepatomegaly and/or raised alanine aminotransferase (ALT). Patients and Methods: Thirty-three overweight and obese children, aged 2-13 years, presenting with hepatomegaly and/or raised ALT, were studied for the prevalence of MS, IR and NAFLD. Laboratory analysis included fasting blood glucose, serum insulin, serum triglycerides (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c) and liver biochemical profile, in addition to liver ultrasound and liver biopsy. Results: Twenty patients (60.6%) were labeled with MS. IR was present in 16 (48.4%). Fifteen (44%) patients had biopsy-proven NAFLD. Patients with MS were more likely to have NAFLD by biopsy (P=0.001). Children with NAFLD had significantly higher body mass index, waist circumference, ALT, total cholesterol, LDL-c, TG, fasting insulin, and lower HDL-c compared to patients with normal liver histology (P< 0.05) and fitted more with the criteria of MS (80% vs. 44%). IR was significantly more common among NAFLD patients (73% vs. 28%). Conclusion: There is a close association between obesity, MS, IR and NAFLD. Obese children with clinical or biochemical hepatic abnormalities are prone to suffer from MS, IR and NAFLD.

Furazolidone-based therapies for Helicobacter pylori infection: A pooled-data analysis
Angelo Zullo, Enzo Ierardi, Cesare Hassan, Vincenzo De Francesco
January-February 2012, 18(1):11-17
DOI:10.4103/1319-3767.91729  PMID:22249086
Background/Aim: Furazolidone-based therapies are used in developing countries to cure Helicobacter pylori infection due to its low cost. The low bacterial resistance toward furazolidone may render appealing the use of this drug even in developed countries. However, some relevant safety concerns do exist in using furazolidone. Patients and Methods : This was a systematic review with pooled-data analysis of data regarding both eradication rate and safety of furazolidone-based therapies for H. pylori infection. Intention-to-treat (ITT) and per-protocol (PP) eradication rates were calculated. Results : Following furazolidone-based first-line therapy, H. pylori eradication rates were 75.7% and 79.6% at ITT and PP analysis, respectively (P<0.001). The overall incidence of side effects and severe side effects were 33.2% and 3.8%, respectively. At multivariate analysis, only high-dose furazolidone was associated with increased therapeutic success (OR: 1.5, 95% CI: 1.3-2.7; P<0.001), while occurrence of side effects was relevant following treatment for a long duration (OR: 2.9, 95% CI: 2.2-4.1; P<0.001), high-dose furazolidone (OR: 2.3, 95% CI: 1.7-3.2; P<0.001) and bismuth-containing regimens (OR: 2.1, 95% CI: 1.5-2.8; P<0.001). Conclusions: Furazolidone-based regimens usually achieve low eradication rates. Only a high-dose regimen improves the cure rate, but simultaneously increases the incidence of severe side effects. Therefore, we suggest that patients have to be clearly informed about the possible genotoxic and carcinogenetic effects for which furazolidone use is not approved in developed countries.

Hepatocellular carcinoma in hepatitis D: Does it differ from hepatitis B monoinfection?
Zaigham Abbas, Mustafa Qureshi, Saeed Hamid, Wasim Jafri
January-February 2012, 18(1):18-22
DOI:10.4103/1319-3767.91731  PMID:22249087
Background/Aim: Hepatitis D virus (HDV) superinfection in patients with chronic hepatitis B leads to accelerated liver injury, early cirrhosis, and decompensation. It may be speculated that hepatocellular carcinoma (HCC) may differ in these patients from hepatitis B virus (HBV) monoinfection. The aim of this study was to compare clinical aspects of hepatocellular carcinoma in patients of hepatitis D with HBV monoinfection. Patients and Methods: A total of 92 consecutive HCC cases seropositive for antibody against HDV antigen (HDV group) were compared with 92 HBsAg-positive and anti-HDV-negative cases (HBV group). Results: The features including sex, body mass index, presence of ascites, serum biochemistry, gross tumor appearance, child class, barcelona cancer liver clinic and okuda stages were not significantly different between the 2 groups. Decreased liver size was noticed more in cases of HDV compared with HBV group where the liver size was normal or increased (P=0.000). HDV patients had lower platelets (P=0.053) and larger varices on endoscopy (P=0.004). Multifocal tumors and elevated alpha-fetoprotein level >1000 IU/mL were more common in HBV group (P=0.040 and P= 0.061). TNM classification showed more stage III-IV disease in HBV group (P=0.000). Conclusion: Decreased liver size and indirect evidence of more severe portal hypertension and earlier TNM stage compared with HBV monoinfection indicate that HDV infection causes HCC in a different way, possibly indirectly by inducing inflammation and cirrhosis.

Herbal medicine in the treatment of ulcerative colitis
Fei Ke, Praveen Kumar Yadav, Liu Zhan Ju
January-February 2012, 18(1):3-10
DOI:10.4103/1319-3767.91726  PMID:22249085
Ulcerative colitis (UC) is a refractory, chronic, and nonspecific disease occurred usually in the rectum and the entire colon. The etiopathology is probably related to dysregulation of the mucosal immune response toward the resident bacterial flora together with genetic and environmental factors. Several types of medications are used to control the inflammation or reduce symptoms. Herbal medicine includes a wide range of practices and therapies outside the realms of conventional Western medicine. However, there are limited controlled evidences indicating the efficacy of traditional Chinese medicines, such as aloe vera gel, wheat grass juice, Boswellia serrata, and bovine colostrum enemas in the treatment of UC. Although herbal medicines are not devoid of risk, they could still be safer than synthetic drugs. The potential benefits of herbal medicine could lie in their high acceptance by patients, efficacy, relative safety, and relatively low cost. Patients worldwide seem to have adopted herbal medicine in a major way, and the efficacy of herbal medicine has been tested in hundreds of clinical trials in the management of UC. The evidences on herbal medicine are incomplete, complex, and confusing, and certainly associated with both risks and benefits. There is a need for further controlled clinical trials of the potential efficacy of herbal medicine approaches in the treatment of UC, together with enhanced legislation to maximize their quality and safety.

Ahmed S Gado, Basel A Ebeid, Aida M Abdelmohsen, Anthony T Axon
January-February 2012, 18(1):34-39
DOI:10.4103/1319-3767.91737  PMID:22249090
Background/Aim: Acute upper gastrointestinal hemorrhage (AUGIH) is a life-threatening emergency that results in high morbidity and mortality. The mortality rate varies between 4% and 14%. The aim of the study was to determine the clinical outcome of AUGIH among patients admitted to a government hospital in Egypt. Patients and Methods: This was a cross-sectional hospital-based study performed in 1000 patients presenting with AUGIH over a 7-year period between January 2004 and January 2011. Results: One thousand patients were analyzed. Fifty-four percent were male. Mean age was 52 ± 17 years. Eighty-eight percent were emergency admissions and 12% were inpatients at the time of bleeding. At presentation 68% had major comorbidity and 50% had liver disease. Seven hundred and twenty-four patients (72%) underwent endoscopy. Bleeding varices accounted for 31% of AUGIH and peptic ulcer 28%. Two hundred and thirty-two patients had endoscopically diagnosed bleeding varices or peptic ulcer with a visible vessel or active bleeding. These received endoscopic therapy. Initial hemostasis was achieved in 207 (89%). Thirteen patients (6%) had therapy at a subsequent endoscopy for further bleeding. Surgery was performed on 9 patients (0.9%) with AUGIH. Complications were reported in 70 patients (7%) mainly liver failure (4%). Six hundred and eighty-four patients (68%) were discharged improved, 162 (16%) left hospital without a diagnosis and 4 (0.4%) were referred to another facility. The overall mortality was 15%. Mortality was 24% in patients ≥60 years, 37% among inpatients, and 21% in those who had a major comorbidity. Mortality was 22% in patients who had liver disease and 9% in variceal bleeding. Conclusion: The most common cause of AUGIH was variceal in origin. Endoscopic therapy was successful in most cases. Mortality after AUGIH was particularly high among elderly patients, inpatients, and patients who had a major comorbidity, liver disease, and variceal bleeding.

Yasir M Khayyat
January-February 2012, 18(1):23-25
DOI:10.4103/1319-3767.91733  PMID:22249088
Background/Aim: To identify the prevalence of gluten sensitivity in a healthy adult Saudi population within a low endemic area of celiac disease using IgA tissue transglutaminase antibody. The study was conducted as a prospective pilot study for Saudi attendees of a blood donation centre at King Faisal Specialist Hospital & Research Centre in Jeddah, Saudi Arabia. Patients and Methods: Individuals were invited to participate in the study and screened for gluten sensitivity using immunoglobulin A tissue transglutaminase antibody (IgA TTG) along with serum IgA level. Descriptive data was presented and expressed as mean value; correlation between variables was estimated using Pearson correlation, and nonparametric data using Pearson rho correlation (level of P value <0.05 is considered to be statistically significant). Results: Two hundred and four individuals (122 males and 82 females, mean age 35 years) attending the blood donation centre were screened. Three individuals tested positive for IgA TTG showing normal IgA level (1 female and 2 males) with a 1.5% prevalence in the cohort. Conclusions: Positive celiac screening is present at a low prevalence rate in our adult population, in which the individuals' age and their serum IgA levels are not associated with the positivity level. A study on a larger scale with the application of histologic confirmation of positive cases is needed.

Alexander Swidsinski, Yvonne Dörffel, Vera Loening-Baucke, Alexander Tertychnyy, Salbakay Biche-ool, Sergei Stonogin, Yi Guo, Ning-Dong Sun
January-February 2012, 18(1):55-58
DOI:10.4103/1319-3767.91734  PMID:22249094
Background/Aim: To investigate the geographic occurrence of mucosa-invading Fusobacteria in acute appendicitis. Patients and Methods: Carnoy- and formalin-fixated appendices from Germany, Russia, and China were comparatively investigated. Bacteria were detected using fluorescent in situ hybridization. Cecal biopsies from patients with inflammatory bowel disease and other conditions were used as disease controls. Results: Fusobacteria represented mainly by Fusobacterium nucleatum were the major invasive component in bacterial infiltrates in acute appendicitis but were completely absent in controls. The occurrence of invasive Fusobacteria in Germany, Russia, and China was the same. The detection rate in Carnoy-fixated material was 70-71% and in formalin-fixated material was 30-36%. Conclusions: Acute appendicitis is a polymicrobial infectious disease in which F. nucleatum and other Fusobacteria play a key role.

Nazish Butt, Syed H Shah, Abdul R Alvi, Tanveer-ul-Haq , Saba Hassan
January-February 2012, 18(1):68-70
DOI:10.4103/1319-3767.91732  PMID:22249097
Situs inversus totalis is a rare autosomal recessive congenital anomaly that is characterized by mirror image anatomy of the abdominal and thoracic organs. We report a case of a 28-year-old male with situs inversus totalis, who developed an idiopathic ileoileal and ileocolic intussusception, which was diagnosed on computed tomography scan. Patient underwent successfully ileal resection and side-to-side functional anastomosis of ileum 12 cms from ileocecal junction. Postoperative course was uneventful. To the best of our knowledge, this is the first case of idiopathic adult intussusception with situs inversus totalis in the literature.

Mortada H El-Shabrawi, Hanaa M El-Karaksy, Sawsan H Okahsa, Naglaa M Kamal, Gamal El-Batran, Khaled A Badr
January-February 2012, 18(1):26-33
DOI:10.4103/1319-3767.91735  PMID:22249089
Background/Aim: We aim to investigate the safety of outpatient blind percutaneous liver biopsy (BPLB) in infants and children with chronic liver disease (CLD). Patients and Methods: BPLB was performed as an outpatient procedure using the aspiration Menghini technique in 80 infants and children, aged 2 months to 14 yrs, for diagnosis of their CLD. Patients were divided into three groups: Group 1 (<1 year), group 2 (1-6 yrs), and group 3 (6-14 yrs). The vital signs were closely monitored 1 hr before biopsy, and then 1, 2, 6, and 24 hrs after biopsy. Twenty-four hours pre- and post-biopsy complete blood counts, liver enzymes, prothrombin time (PT), and abdominal ultrasonography, searching for a biopsy-induced hematoma, were done for all patients. Results: No mortality or major morbidities were encountered after BPLB. The rate of minor complications was 17.5% including irritability or "pain" requiring analgesia in 10%, mild fever in 5%, and drowsiness for >6 hrs due to oversedation in 2.5%. There was a statistically significant rise in the 1-hr post-biopsy mean heart and respiratory rates, but the rise was non-significant at 6 and 24 hrs except for group 2 where heart rate and respiratory rates significantly dropped at 24 hrs. No statistically significant difference was noted between the mean pre-biopsy and the 1, 6, and 24-hrs post-biopsy values of blood pressure in all groups. The 24-hrs post-biopsy mean hemoglobin and hematocrit showed a significant decrease, while the 24-hrs post-biopsy mean total leucocyte and platelet counts showed non-significant changes. The 24-hrs post-biopsy mean liver enzymes were non-significantly changed except the 24-hrs post-biopsy mean PT which was found to be significantly prolonged, for a yet unknown reason(s). Conclusions: Outpatient BPLB performed by the Menghini technique is safe and well tolerated even in infants and young children. Frequent, close monitoring of patients is strongly recommended to achieve optimal patient safety and avoid potential complications.

Muhammad Z Bawany, Osama Alaradi, Ali Nawras
January-February 2012, 18(1):59-61
DOI:10.4103/1319-3767.91728  PMID:22249095
Caroli's syndrome is characterized by bile duct ectasia in association with hepatic fibrosis. It is usually transmitted in an autosomal recessive fashion and has been well documented to be associated with autosomal recessive polycystic kidney disease and occasionally with autosomal dominant polycystic kidney disease. However, there has been only few case reports published with Caroli's syndrome diagnosed postrenal transplantation.

Successful closure of pharyngo-cutaneous and phayryngo-tracheal fistulas using removable hypopharyngeal stent after laryngectomy for laryngeal carcinoma
Mohamad A Eloubeidi, Desiree E Morgan, William R Carroll, Lawrence F Johnson
January-February 2012, 18(1):62-67
DOI:10.4103/1319-3767.91730  PMID:22249096
Placement of removable stents to close pharyngo-cutaneous and tracheo-pharyngeal fistulas after laryngectomy has not been reported before. This case presents the feasibility of removable esophageal stent in closing pharyngo-cutaneous and tracheo-pharyngeal fistulas after laryngectomy for laryngeal cancer. Consecutive patients who underwent placement of removable esophageal stent for closing pharyngo-cutaneous and tracheo-pharyngeal fistulas after laryngectomy for laryngeal cancer. Three patients underwent successful stent placement in the hypopharynx. The stents were well tolerated. Patient one had the stent for 14 months, leading to complete healing of the fistula. Removal was successful. The second patient was palliated but died 8 weeks after stent placement. The third patient has successful palliation of his tracheo-esophageal fistula and the stent is being exchanged every 3-4 months to palliate his fistula. Closure of pharyngo-cutaneous and tracheo-esophageal fistulas is feasible with esophageal removable stents. These stents provide alternative options when dealing with these challenging problems.

Mona E Fahmy, Mahmoud A Osman, Rehab A Mahmoud, Lamiaa K Mohamed, Khaled I Seif-elnasr, Ayman E Eskander
January-February 2012, 18(1):40-43
DOI:10.4103/1319-3767.91739  PMID:22249091
Background/Aim: Among the various methods for evaluating gastric emptying, the real-time ultrasound is safe, does not require intubation, or rely on either radiologic or radionuclide technique. The aim of our work was to measure the gastric emptying in pediatric patients with portal hypertension by using the real-time ultrasound. Patients and Methods: Forty patients with portal hypertension with mean age 7 ± 2.8 years and 20 healthy children as a control group underwent gastric emptying study by using real-time ultrasound. The cross-sectional area of the gastric antrum was measured in the fasting state and then each subject was allowed to drink tap water then calculated by using formula area (π longitudinal Χ anteroposterior diameter/4). The intragastric volume was assumed to be directly proportional to the cross-sectional area of the antrum. Results: The mean gastric emptying half-time volume was significantly delayed in portal hypertension patients (40 ± 6.8 min) compared with the control subjects (27.1 ± 3.6) min (P<0.05). Patients with extrahepatic portal vein obstruction had significant delayed gastric emptying in comparison to patients with portal hypertension due to other etiologies (36.14 ± 4.9 vs 44.41 ± 6.04 min; P<0.01). Conclusion: Ultrasound is a noninvasive and a reliable method for measuring gastric emptying in pediatric patients. Gastric emptying was significantly delayed in patients with portal hypertension. Etiology of portal hypertension may influence gastric emptying time in patients with chronic liver disease.

Health care providers' acceptance of unsedated colonoscopy before and after a state-of-the-art lecture on the feasibility of the option
Felix W Leung, Abdulrahman Aljebreen
January-February 2012, 18(1):50-54
DOI:10.4103/1319-3767.91736  PMID:22249093
Background/Aim: The impact of education on acceptance of unsedated colonoscopy by health care providers is unknown. To test the hypothesis that knowledge imparted by a lecture on unsedated colonoscopy is associated with its enhanced acceptance. Settings and Design: At the State-of-the-Art Lecture on "Unsedated colonoscopy: Is it feasible?" presented at the 8 th Pan-Arab Conference on Gastroenterology, February, 2011, Riyadh, Saudi Arabia, a questionnaire survey of the audience was undertaken. Materials and Methods: An expectation questionnaire was administered before and after the lecture. Attendees responded anonymously. Statistical analysis used: The responses of a convenient sample of 49 attendees who provided completed responses to the questionnaire both before and after the lecture were analyzed. Data are expressed as frequency counts and means±SEM. Repeated measures analysis of variance (ANOVA), ANOVA with contrasts and Chi-square analysis (Statview II Program for Macintosh computers) were used to assess the data. A P value of <0.05 is considered significant. Results and Conclusions: The mean±SEM credibility score (maximum possible score=50) was 25.8 ± 1.8 before and 33.3 ± 2.1 after the lecture, with a significant improvement in mean score of 7.5 ± 1.3 (P=0.001, paired t test). Nineteen (39%) respondents were not willing to consider unsedated colonoscopy for themselves before the lecture. This number decreased to 13 (27%) after the lecture. Before the lecture only 4 (8%) respondents were willing to consider unsedated colonoscopy for themselves. After the lecture this number increased to 8 (16%). The data suggest education of healthcare professionals regarding the feasibility of unsedated colonoscopy appears to enhance its acceptance as a credible patient care option at a Pan-Arab Gastroenterology Conference.
