11/25. enterobius vermicularis and perianal sepsis in children. Specific aetiological factors are responsible for a significant proportion of cases of perianal sepsis in children. A rarely implicated pathogen is enterobius vermicularis, an obligate parasite with a ubiquitous presence in children. The authors describe two unequivocal instances of threadworm involvement in perianal sepsis, suggesting a pathophysiological basis. ( info) |
12/25. Perianal mass and recurrent cellulitis due to enterobius vermicularis. A unique case of enterobiasis presenting as recurrent cellulitis and a perianal mass in a six-year-old girl is reported. Complicated perianal lesions due to enterobius are unusual. Only 10 previous cases are known, with unclear pathogenesis in most of them, although mucosal breaches and perianal crypt or gland entry have been postulated. The association of the mass in this case with a deep crypt, and the histopathologic finding of squamous epithelium focally surrounding the granulomatous reaction to the enterobius eggs suggest that the worm entered the perianal tissues via a crypt. Local secondary bacterial infection can cause significant morbidity. Surgical excision of such granulomatous mass lesions is necessary in symptomatic or complicated cases. ( info) |
13/25. pelvic pain caused by intraperitoneal enterobius vermicularis (threadworm) ova with an associated systemic autoimmune reaction. AIM: The aim of this paper, based on a case study was two-fold; firstly to review the sites and gynecologic complications of ectopic enterobius vermicularis and secondly study the autoimmune accompaniments of parasitic infestations. methods: A case of intraperitoneal ectopic enterobius vermicularis, with accompanying autoimmune signs and symptoms, is presented and its response to surgical and medical treatment described. A medical literature search was carried out into the subject of ectopic enterobius vermicularis, particularly from the gynecologic perspective along with a study of autoimmune activation associated with parasitic infestation. RESULTS: pelvic pain was found to be caused by chronic inflammation from ectopic enterobius vermicularis. This was treated both surgically and medically, with the surgical treatment proving to be inadequate but with a good response to immune modification. In the literature ectopic enterobius vermicularis was found to be treatable surgically. CONCLUSION: Ectopic enterobius vermicularis was found to create symptomatic inflammatory lesions that could be treated surgically and an associated autoimmune response treatable by immune modification.

14/25. Appendiceal enterobius vermicularis infestation associated with right-sided chronic pelvic pain. Parasitic infestation is an uncommon cause of chronic pelvic pain among women of reproductive age. A case of chronic right-sided pelvic pain associated with appendiceal enterobius vermicularis infestation was managed with appendectomy and antiparasitic therapy resulting in a complete resolution of symptoms.

| We report a 20-year-old man who presented with abdominal discomfort for 2 months. colonoscopy showed skip areas with ulceration, resembling Crohn's disease. Biopsies showed chronic inflammation and a non-necrotizing granuloma. An adult pinworm was found in the lumen from an uninvolved segment. The patient responded to mebendazole. ( info) |
16/25. Unexpected causes of gynecological pelvic pain. During our day-to-day practice, we, as clinicians, occasionally come across patients whose symptomatology is atypical. In major teaching hospitals, it is usually easy to consult with other specialists to optimize patient management and standard of care. Our study patients were treated by the authors between January 1998 and January 2003. In this article, the authors report on 6 different cases of unexpected causes of pelvic pain, all of which were managed in a general gynecological unit at a major tertiary referral institution.

17/25. Unusual endoscopic and microscopic view of enterobius vermicularis: a case report with a review of the literature. enterobius vermicularis has the broadest geographic range of any helminth and is the most common intestinal parasite seen in the primary care setting. Underappreciated is the fact that it is not always a benign disorder and could even cause life-threatening medical problems. Visualization of the actual worms during endoscopy is probably underappreciated in part because endoscopists have never actually seen the worm and/or are not actively looking for, or anticipating, worms. This report describes a case of worm infection as documented during colonoscopy and confirmed by microscopy. The gross and microscopic appearance of the worm is described. literature regarding the wide range of gastrointestinal and nongastrointestinal manifestations, including potentially life-threatening illnesses, as well as treatment options, are also reviewed.

18/25. Eosinophilic colitis associated with larvae of the pinworm enterobius vermicularis. Various helmintic parasites, most of which are uncommon in economically developed countries, can cause abdominal pain and eosinophilic inflammation of the bowel. A homosexual man presented with severe abdominal pain and haemorrhagic colitis, eosinophilic inflammation of the ileum and colon, and numerous unidentifiable larval nematodes in diarrhoeal stool. His symptoms resolved with anthelmintic treatment alone. Using comparative morphology and molecular cloning of nematode ribosomal rna genes, we identified the parasites as larvae of the pinworm enterobius vermicularis, which are rarely observed or associated with disease. Occult enterobiasis is widely prevalent and may be a cause of unexplained eosinophilic enterocolitis. ( info) |
19/25. Perforation of the ileum secondary to enterobius vermicularis report of a rare case. An isolated ileal perforation is presented in a 12-yr-old patient. Microscopic examination revealed granulomatous inflammation due to enterobius vermicularis (pinworm). This is only the third documented report of intestinal perforation involving pinworms. Although infestation with this parasite is generally considered to be relatively harmless, on rare occasions, it can be a significant cause of morbidity due to its potential ability to invade the tissues.

20/25. Live female enterobius vermicularis in the posterior fornix of the vagina of a Korean woman. A 33-year-old Korean woman, para 2. visited an obstetrics and gynecology clinic, Kumi-shi, Kyongsangbuk-do, due to postcoital spotting and flank pain. She had a tubal ligation 7 years before and demonstrated back pain during menstruation. She revealed a foul smelling discharge without complaint of itching. enterobius vermicularis eggs were demonstrated during microscopic examination of a smear taken from the posterior fornix of the vagina. On endoscopic examination of her vagina, a live worm was found in the posterior fornix. The worm was removed and identified as a female E. vermicularis based on morphology. This is the first case report of vaginal enterobiasis in korea. ( info) |
