Specific composition and morphological peculiarities of endemic monogenean parasites of freshwater fishes of Iran

Result obtained during ten years research work (1990-2000) on distribution of monogenean fauna Iranian fishes indicates that its composition of monogenean fauna of Iranian fishes depends on their habit and since Iran includes three different zoogeographical zones with highly endemic fish hosts, its monogenean parasites have specific composition. The Caspian fauna is characterized by relatively great diversity of monogenean species (eleven genera and at least forty-eight species). Presence of some species with sphymoid type of anchors is one of its speciation. The Iranian part of Mezopotomian (Tigris) fauna (six genera and at least twenty-six species) is characterized by distinct monogenean parasites, for instance, presence of Dogielius type of anchors and prevalence of Dactylogyrus spp. with morphilogical peculiarities not similar to Sarmatian fauna. The most of its specific character is the shape of dorsal and ventral bar in Dactylogyrus species found in the Tigris Zone. Endemism in the a forsaid zone is high therefore species of Dactylogyrus will be increased more. The oriental monogenean fauna of Iran (three genera and at least eleven species) shows special characteristics, amongthem, the presence of one connective dorsal bar only, presence of varicorhinoid type of bar and haptor would suggest that aforesaid zone of Iran has been influenced by the Indian fauna

Foreign body impacted in the Jejunum

We present a case with protracted vomiting which admitted to our hospital. After radiologic investigation, patients underwent laparotomy, were a foreign body was found impacted in the jejunum. Index Word: foreign body, jejunum, impaction, intestinal obstruction

Trichohepatoenteric Syndrome or Syndromic Diarrhea—Report of Three Members in a Family, First Report from Iran

Introduction. Intractable diarrhea of infancy (IDI) includes several types of early onset diarrhea; one of the rare etiologies is trichohepatoenteric (THE) syndrome, also known as syndromic diarrhea (SD) which was primarily described by Stankler et al. Hereby we report a family with several affected members which to our knowledge is the first case report from Iran. Report of Cases. A three-year-old boy referred with short stature, poor weight gain, and intermittent steatotic diarrhea to our center. He was born to healthy, relative parents (cousins). He did not gain any weight after four months of age and began having intermittent steatotic diarrhea, abdominal distension, and fever. He was hospitalized several times. Two other children in the family also showed somewhat similar symptoms. Two sweat tests were negative for cystic fibrosis. Workup for Celiac disease was performed several times which was negative; however, gluten-free diet was tried several times which was not effective. Workup for Hirschsprung’s disease was performed but colon was ganglionic. Evidence of liver involvement was approved by elevated liver enzymes and coarse echo of liver on sonography. Discussion. Trichoenterohepatic syndrome should be put in mind in cases of intractable diarrhea presenting in a family with several affected members. Early diagnosis would save patients from unnecessary workups
