Abdominal hydatid cyst with presentation of ovarian cyst in ultrasonography: case report

Background: Hydatid cyst is an endemic disease in Iran and many middle eastern countries. The clinical presentation of Echinococcus granulosus infection depends upon the site of the cysts and their size. Small and/or calcified cysts may remain asymptomatic indefinitely. However, symptoms due to mass effect within organs, obstruction of blood or lymphatic flow, or complications such as rupture or secondary bacterial infections can result. The most common involved organs with this parasite are the liver and lung. Unusual areas of the disease include breast, adrenal, appendix, peritoneum, omentum and mesenteric. The purpose of this study was to report a rare case of abdominal hydatid cyst with presentation of ovarian cyst in ultrasonography. Case Presentation: A 26-year-old virgin woman with abdominal pain in the hypogastric region and lower and right quadrant of the abdomen, with gastric fullness and without nausea and vomiting referred to an emergent unit of Ghaem Hospital (an academic hospital of Mashhad University of Medical Sciences) in June 2017. In an ultrasound, a cyst of 95×105 mm in right adnexa of uterus was seen. Due to continued abdominal pain, laparotomy was performed for the patient. At the time of laparotomy, the ovaries, uterus and adnexa were completely normal. A 10×15 cm cyst was seen with a thin wall which adhering to the omentum and the small end of the stomach. Frozen section biopsy reported hydatid cyst. Conclusion: Considering that hydatid cyst is endemic in Iran, the presence of cystic mass in the peritoneal cavity, hydatid cyst should be considered. To prevent complications and relapse, it is best to avoid cyst rupture during surgery as much as possible

Role of the Lewis and ABO Blood Group Antigens in Helicobacter pylori Infection

Background: Helicobacter pylori infection is a major risk factor for chronic gastritis and gastric cancer. Some findings show increased frequencies of these diseases in individuals with type O blood and in secretors (expressing Leb antigen), but other studies have not found any relationship between blood groups and this infection. Given that H. pylori infection and gastric cancer are common in Iran, the assessment of the pathogenesis of this infection in relation to these blood groups could be valuable. Methods: In a cross-sectional study, we determined the ABO and Lewis blood groups of participants using the tube method and evaluated the level of anti-H. pylori immunoglobulin G using an enzyme-linked immunosorbent assay. This study included 171 Iranian blood donors from Mashhad, Iran, during 2010. The significance of the differences in the frequencies of the Lewis and ABO phenotypes between individuals infected with and without H. Pylori infection were tested using the Chi-square test. A P-value < 0.05 was considered significant. Results: H. pylori infection was found in 76.6% of the study subjects (n = 131). The most common ABO blood group was O (33.9%), and the most common Lewis blood group was Le(a-b+) (54.7%). The frequencies of the ABO, Lewis, and secretion phenotypes were not significantly different between the infected and uninfected subjects. Conclusion: We did not find any significant relationship between the Lewis, ABO, and secretion phenotypes and H. pylori infection
