Genotyping pattern among Iranian HCV positive patients

Successful treatment to eliminate HCV RNA depends on the identified genotype. In the present study, we compared the frequency of different HCV genotypes, during four years study [2004 till 2008]. Sera specimens were received from 16 provinces of Iran. We used High Pure Viral Nucleic Acid Purification kit for extraction and samples were tested with improved form of RT-PCR technique. HCV genotypes were determined using Amplisense PCR kit and Amplicor HCV Monitoring Version 2 test utilized a reverse transcription [RT]-PCR approach to quantitative HCV RNA. Two hundreds six HCV positive specimens were entered to the study out of 389 tested samples. Type 3a was the most frequent type [46.6%], followed by type 1 [including 1a and 1b with 25.73% and 17.47% for each respectively] with 43.2%. Looking through collected results of the four years study confirmed the rate of HCV infection in those single genotypes 1b, 3a were slightly increased from 12.22% and 38.88% in the first year to 18.66 and 46.51% in the fourth year of the study period. The analyzed data proved that some patients were infected with two different types. High viral load was also more correlated to genotype 1 than other types

Repair of iatrogenic large colon perforation using laparoscopic methods. Case report and review of the literature

Iatrogenic perforation of the colon during elective colonoscopy is a serious complication. Surgical treatment remains the standard of care. We report a patient with a large colonic perforation that occurred during a screening colonoscopy, successfully repaired with laparoscopic methods. Although the safety and efficacy of this approach is not entirely established, laparoscopy can be used to treat iatrogenic colonic perforation when the defect is readily recognized, easily accessible for closure and the bowel preparation is excellent. A laparoscopic approach to treat iatrogenic colon perforation results in decreased morbidity and hospital stay, in addition to a shorter incision length compared to an open method. In those cases where it is feasible and the surgical skill exists, a laparoscopic attempt at colon repair should probably be the initial clinical approach

[Assessing sensitivity, specificity and accuracy of a modified rapid urease kit for clinical diagnosis of Helicobacter pylori]

Rapid urease test is increasingly used as a cheap and quick procedure with high specificity for clinical detection of Helicobacter pylori worldwide. To evaluate the functionality of a rapid urease kit manufactured by Pasteur institute of Iran in 2002, with some modifications compared with other common kits. During a clinical trial in Baghiatallah hospital, Tehran, the sensitivity, specificity and accuracy of the kit was investigated. This was an experimental study in which 91 patients suspected of having H pylori infection were examined. Following collection of history and clinical symptoms, the endoscopic signs of all patients were also recorded. Each endoscopic specimen was carefully examined in three ways with no previous knowledge of operator as follows: 1. Detection of urease test using modified rapid urease kit. 2. Detection of urease test using certified commercial kit. 3. Pathologic examination as the gold standard method. Regarding the results of present study, employing modified rapid urease kit produced positive results on 78.8% of pathologically positive samples. When negative pathologic samples were tested with modified kit, 89.7 % of samples found to be negative. The differences observed between the results of two tests were statistically significant [p=0.001]. Using modified rapid urease kit also produced a false positive rate of 4.4%. Based on our data, it was shown that the sensitivity, specificity and accuracy of the modified kit were 78.8%, 89.7% and of 83.5%, respectively
