  • We present a case of a 36-year-old Caucasian woman with ascites, elevated CA-125, an enlarged left ovary and chronic pelvic pain who underwent an unnecessary surgical intervention because of suspected malignant disease.[ncbi.nlm.nih.gov]
  • 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.[ncbi.nlm.nih.gov]
Flank Pain
  • 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.[ncbi.nlm.nih.gov]
Burning Micturition
  • Here we present such a case in a 7-year-old girl presenting with fever, pain in the abdomen, vomiting and burning micturition. Ultrasonography and micturating cystourethrogram (MCU) studies were normal.[ncbi.nlm.nih.gov]
Scrotal Pain
  • Orchido-epididymitis by pinworm has to be kept in mind when treating boys with persistent scrotal pain. 2011 The Author(s)/Acta Paediatrica 2011 Foundation Acta Paediatrica.[ncbi.nlm.nih.gov]
Pelvic Pain in Women
  • Abstract Parasitic infestation is an uncommon cause of chronic pelvic pain among women of reproductive age.[ncbi.nlm.nih.gov]


  • A higher proportion of pre-treatment Salmonella spp. was associated with a non-increase in SIgA after mebendazole deworming treatment.[ncbi.nlm.nih.gov]
  • RESULTS: Metronidazole treatment failure was significantly more frequent in patients with E. vermicularis co-infection and in patients with children in the family.[ncbi.nlm.nih.gov]
  • A case of intraperitoneal ectopic Enterobius vermicularis, with accompanying autoimmune signs and symptoms, is presented and its response to surgical and medical treatment described.[ncbi.nlm.nih.gov]
  • While there have been limited reports of ectopic enterobiasis throughout the world, ours is probably one of the rarest reports of recurrent vaginal E. vermicularis infection in the absence of any gastrointestinal symptoms despite complete treatment.[ncbi.nlm.nih.gov]
  • Increased awareness is necessary to avoid an unnecessary surgery and to choose the correct antibiotic treatment.[ncbi.nlm.nih.gov]


  • Even though the prognosis for pinworm infection is very good, complications can set in.[encyclopedia.com]


  • The etiologic agent was the parasite Enterobius vermicularis.[ncbi.nlm.nih.gov]
  • Parasitic infections should be kept in mind in patients clinically suspected of having acute appendicitis, and treatment procedures should be adopted according to the etiology.[ncbi.nlm.nih.gov]
  • Arguments for considering the parasite to be of etiologic significance in the production of the pathologic changes and clinical symptoms are presented.[ncbi.nlm.nih.gov]
  • Reports indicate that the parasitic infection constitutes a percentage of the etiologies in appendicitis and fecalitos are the most common trigger, some parasites (Enterobius vermicularis) may be involved in its formation, although this percentage is[ncbi.nlm.nih.gov]
  • Abstract Enterobius vermicularis , coomonly known as pinworm, in the etiologic agent of the the most pervalent nematode infection of humans in temperate climates, affecting mainly children less than 12 years of age.[link.springer.com]


  • This epidemiological survey was performed to describe the profile of E. vermicularis infection in schoolchildren in Miaoli County and Taichung County.[ncbi.nlm.nih.gov]
  • Author information 1 Norwegian Institute of Public Health,Division of Epidemiology, Oslo,Norway. 2 Norwegian Institute of Public Health,Division of Institute Resources, Oslo,Norway. 3 Oslo University Hospital,Rikshospitalet, Department of Pediatric Research[ncbi.nlm.nih.gov]
  • Numerous studies have suggested that eggs of intestinal nematodes, primarily Enterobius vermicularis (pinworm), can serve as vectors for D. fragilis, although attempts to culture D. fragilis from pinworm eggs have been unsuccessful and data from epidemiological[ncbi.nlm.nih.gov]
  • epidemiology classification and characteristics transmission and infection clinical manifestations diagnosis treatment Epidemiology E. vermicularis is found worldwide but is most common in temperate regions, where person-to-person transmission is greatest[sharinginhealth.ca]
  • Detailed descriptions of history, life cycle, and epidemiology are given. In addition to hygienic measures useful in treatment, the particulars of drug therapy are also outlined.[ncbi.nlm.nih.gov]

  • The authors describe two unequivocal instances of threadworm involvement in perianal sepsis, suggesting a pathophysiological basis.[ncbi.nlm.nih.gov]
  • Pathophysiology Images hosted on other servers: Life cycle Clinical features Usually more common in temperate climates Usually found in appendix of children ages 7 - 11 years as incidental finding Mass of worms may cause obstruction May occasionally be[pathologyoutlines.com]


  • Prompt recognition and a high clinical index of suspicion are required to prevent an unnecessary appendicectomy. Caution is advised when performing a laparoscopic appendectomy, as in our case, to prevent contamination of the peritoneum.[ncbi.nlm.nih.gov]
  • To prevent unnecessary appendectomy, this type of infection should be made to ask in the history and clinical findings of patients.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: Co-infection with E. vermicularis may act as a factor favoring D. fragilis infection by preventing eradication measures. This suggests that both parasites should be treated simultaneously. Copyright 2016 The Authors.[ncbi.nlm.nih.gov]
  • Treatment and Prevention Diagnosis of pinworm infection is made by an examination of the patient's anal region.[encyclopedia.com]
