Nematode infections of the eye are common in different parts of the world, but some are usually encountered only in developing nations, such as onchocerciasis and cysticercosis. Ocular toxocariasis is a well-known cause of unilateral ocular disease affecting mainly children and young adults, and is usually caused by T canis. Prevention of ocular toxocariasis is based on such measures as appropriate health care for dogs and cats, including regular anthelmintic treatments, preventing contamination of the environment with feces, and promoting responsible pet ownership [1,49-51]. Onchocerciasis is caused by infection with the filarial parasite O volvulus, and occurs in endemic areas along rivers and streams. In hyperendemic areas almost every person is infected and about half of the population is eventually blinded by onchocerciasis. Because of this, elimination of host-vector contact is very important. DUSN is caused by a motile nematode and is found in the Southeastern and Midwestern United States and in many parts of the world. In Brazil, DUSN is becoming an important cause of posterior uveitis in children and young healthy adults. The destruction of the worm during the early stages of the disease can prevent progression of the visual loss. It is important to remain aware of this entity, not only in areas where it has been described, but also in regions not yet identified as being endemic [52]. Cysticercosis is caused by the encystment of the larvae of the tapeworm T solium, and usually results from ingesting eggs from food, water, or other material contaminated with human feces. Surgical removal of the cyst is usually indicated when possible.

Intestinal parasites are Giardia lamblia, Cryptosporidium parvum, Entamoeba histolytica, hookworms, ascaris, tape worms and others. As to organ parasites, their life-threatening courses are pointed out: amebiasis in the intestine, liver, lung and brain, toxoplasmosis in the brain, lung and heart muscle, including the danger for the child of a pregnant woman with an acute infection, West African sleeping sickness with encephalitis, the East African form with polyserositis, South American Chagas' disease with intestinal and myocardial involvement, visceral leishmaniasis Kala Azar, the filariasis Onchocerca volvulus with threatening blindness, the dog tapeworm with cysts and Echinococcus multilocularis with carcinoma-like infiltration of the liver and other organs, cysticercosis of the brain, eye and muscle tissue; partly generalizing parasitoses in immuno-suppressed including AIDS patients, finally skin parasites as causes of disease (e.g. scabies), and as potential carriers of pathogens.

A wide variety of anomalies may occur as a result of the vitelline duct (VD) failing to obliterate completely. Most reports on symptomatic VD focus on Meckel's diverticulum, while other anomalies are given little attention. A retrospective review was conducted at our institution. According to the records 18 symptomatic children with VD anomalies were seen over 22 years, including 10 boys and 8 girls aged 11 days -14 years (median 7.5 months). Twelve patients aged below 10 years (median 28 days) had patent vitelline ducts (PVDs), 3 children aged 13 months, 13 years and 14 years respectively had Meckel's diverticulum (MD), presenting as inflammation, tapeworm incarceration and volvulus respectively. Two patients, both 8 years old, had umbilical sinus, and a 3-year-old had a vitelline cyst. Only 1 patient with PVD had an associated anomaly (intestinal malrotation). The diagnosis of PVD was obvious clinically, but in 1 patient the fistula was demonstrated by fistulogram. The diagnosis of MD was intraoperative in all 3 patients. Treatment was by various types of resection for PVD and MD and excision for umbilical sinuses and cysts. One patient with PVD developed postoperative intestinal obstruction from adhesions, requiring re-laparotomy and adhesiolysis. Two patients with PVD died from sepsis and anaesthetic-related complications, respectively. Although MD is the most commonly VD anomaly, PVD is the most common symptomatic presentation in our environment.

Taenia saginata infection is caused by the bovine tapeworm and can be the cause of emergency surgical conditions. We report one case of small bowel obstruction leading to necrosis and another case of large bowel obstruction and volvulus due to an impacted tapeworm. The diagnosis of these rare circumstances is usually made intraoperatively.

A 13-year-old Standardbred gelding was referred for evaluation of continuous abdominal pain. Rectal examination revealed a dislocated large colon (Dislocatio coli ad dextram). The horse showed muscle fasciculations and appeared lethargic. It was sent to surgery because of persistent colic. In transit the gelding showed an unstable walk and immediately prior to surgery a wide-based stance in the hindlimbs. Laparotomy revealed a retroflexion of the large colon and a secundary mesenterial volvulus. After surgery the horse remained recumbent. Due to the comatose state and poor prognosis the gelding was euthanized after 15 hours of recumbency. Necropsy indicated hyperaemic meninges, edema of gliacells and submeningeal tissue with vacuolization and loss of several cerebellar Purkinjecells as well as multiple conglomerates of Alzheimer type II astrocyte groups within the grey matter. Further findings included marked hepatolipidosis, multiple gastric ulcers, small intestinal hyperaemia with mild mononuclear inflammation, tapeworm-infestation of the caecum and moderate chronic enteritis with eosinophilic component in the large intestine. To the best of our knowledge, this was the first case of a horse with colic and concurrent encephalopathy without primary liver disease described in a German-speaking country.

Taenia saginata (T. saginata) is one of the most common cestode in human. We report a case of intestinal perforation caused due to T. saginata infection. The patient, 54-year-old female, had intermittent abdominal pain, diarrhea and vomiting on referral. Intestinal obstruction and perforation leading to necrosis, and volvulus due to an impacted tapeworm was observed. Histopathological examinations showed acute inflammation with mucosal ulceration, and luminal exudates accompanied by an elongated and flattened segment of the helminth. Taenia infections should be considered in differential diagnosis of peritonitis and gastrointestinal tumors, particularly in endemic countries including Iran.
