Cystic Echinococcosis in Central Iran: G1 and G6 Genotypes in Patients.

Background: Cystic echinococcosis (CE) is caused by Echinococcus granulosus sensu lato. In Central Iran, no molecular information is available on CE in humans. Therefore, in this study, we identified the genotyping of hydatid cysts obtained from patients with CE in central Iran using mitochondrial cytochrome c oxidase subunit I (cox1) gene. Patients and Methods: Hydatid cysts were obtained from 19 patients referred to Shahid Sadoughi, Mojibian, and Mortaz Hospitals, Yazd, Iran from 2018 to 2020. Informed consent was obtained from all included patients. After DNA extraction, amplification was done using cox1 gene. Phylogenetic analysis was performed using MEGA7. Results: Of the 19 patients, 11 (57.9%) were male and eight (42.1%) were female. The mean age of the patients was 35.645 ± 2.55 years old. Regarding cyst location, of eight isolates from lung, six and two belonged to G1 and G6, respectively; and all liver cysts were G1 genotype. The spleen and neck cysts had G1 and G6 genotypes, respectively (p > 0.05). All cysts with a diameter in the range of 5-10 cm (n = 9) and large cysts (>10 cm; n = 5) were identified as G1 (p = 0.002). The maximum likelihood tree topology demonstrated the maximum similarity of G1 among Iran and worldwide (99%-100% likelihood). Conclusions: Based on our results, it seems that the sheep-dog cycle in the infection of humans by Echinococcus granulosus in this study area has the most important role compared with the other cycles such as the camel-dog one.

Inflammatory myofibroblastic tumor of the small intestine: A case report.

INTRODUCTION: Inflammatory myofibroblastic tumor (IMT) is a rare benign tumor. Usually seen in children and adolescents, this inflammatory tumor can affect all the organs. PRESENTATION OF CASE: In this case, a five-year-old child experienced the sudden onset of symptoms and the enlargement of abdominal mass 20 days before referral. The patient did not have any symptoms of nausea, vomit, and abdominal pain. In the laparotomy, a large and sticky solid mass, attached to the ileum with the mesenteric origin, sized 10×8cm was observed and completely resected. DISCUSSION: This tumor rarely emerges in the small intestine, and there are a few patients with intestinal manifestation. In this case report, the tumor had an origin of the small intestine mesenteric and it had invaded to the ileum. CONCLUSION: Despite using some radiographic methods such as medical ultrasound and computerized tomography (CT) scan to diagnose the disease, the definitive diagnosis is merely possible thorough complete surgical resection.

Peritonitis Following Duodenal Ulcer Perforation in a Newborn: A Case Report.

Duodenal ulcer is an uncommon condition in children, that is why it is not usually considered as the differential diagnosis unless it presents with complications including perforation and haemorrhage. Moreover, duodenal ulcer perforation is an uncommon entity in paediatric age group. Early diagnosis and treatment is crucial in order to improve survival. A three-day-old male neonate was admitted to our hospital because of abdominal distension. The neonate was lethargic. He underwent laparotomy. There was a perforated ulcer, 5×5mm in size, on the anterior aspect of the first part of the duodenum. The perforated ulcer was closed with a single layer. Six-month follow-up revealed no abnormality.

Pseudo-Exstrophy of Bladder with Unilateral Renal Agenesis: A Rare Combination of two Anomalies.

Pseudo-exstrophy of bladder is an uncommon condition characterized by the major musculoskeletal defects without urinary system defects. A two-day-old female neonate was presented with pseudo-exstrophy of the bladder and unilateral renal agenesis- A rare combination of two anomalies. She was born at 37 weeks gestational age with caesarean section delivery. The X-ray of hip revealed pubic diastasis. Ultrasonography clearly showed absence of the left kidney with a normal right kidney. The patient was treated successfully with proper surgical management. We, hereby, report a rare variant case of pseudo-exstrophy of bladder with lower set umbilicus and infra-umbilical midline of lower anterior abdominal wall defect in a neonate who was born in Shahid Sadoughi Hospital, Yazd, Iran.
