Eggs containing larvae of Enterobius vermicularis in vaginal smear.

Pequeno atlas de Parasitologia

Directory of Open Access Journals Sweden. Full Text Available Enterobius vermicularis also known commonly as pinworm is the most common intestinal parasite.

It is a nematode that inhabits the human terminal ileum, colon and appendix. The fertilized female migrates to the perianal area where eggs are deposited but occasionally introduces itself into adjacent orifices, most commonly the female genitourinary tract. Thus the eggs can be seen in the vaginal smear as a result of contamination.

We report a case wherein the patient presented with signs and symptoms of vulvovaginitis. In her vaginal smear there were eggs of Enterobius vermicularis which showed a coiled larva within it. In the background there were plenty of acute inflammatory cells. This patient responded favorably to antihelminthics. We report this case to highlight the morphology of the parasite and also to emphasize that such findings should not be neglected. Timely reporting and appropriate treatment of such cases will prevent further complications of this parasite including endometritis, salphingitis and peritonitis.

While the presence of pinworm eggs in archaeological samples has been reported by many researchers in the New World, those have been detected very scarcely in the Old World, especially in East Asian countries.

In fact, many parasite species were recovered from the archeological remains in Korea, eggs of Enterobius vermicularis had not been found. Recently, a female mummy buried in the 17th century was discovered in the Joseon tomb from Dangjin-gun, Chungcheongnam-do, Korea.

After rehydration process for 12 days, investigations were carried on the luminal surface of the colon. From them, 3 eggs of E. They were elliptical, transparent with a thin egg shell, morvologia This is the first discovery of E. The human pinworm had already been found in other pre-historic archaeological sites in America, and its introduction in this continent is discussed. DNA of Dientamoeba fragilis detected within surface-sterilized eggs of Enterobius vermicularis.

With no evidence of a cyst stage, the mode of transmission of Dientamoeba fragilis, an intestinal protozoon of common occurrence and suggested pathogenicity, is incompletely known. Numerous studies have suggested that eggs of intestinal nematodes, primarily Enterobius vermicularis pinwormcan The aim of this study was to investigate whether we could detect D.

In cellophane tape samples from Egg positive rate of Enterobius vermicularis among preschool children in Cheongju, Chungcheongbuk-do, Korea. In an attempt to determine the prevalence of pinworm infection, the egg positive rate of Enterobius vermicularis was examined using the adhesive cello-tape anal swab method in 1, preschool children sampled from a total of 20 kindergartens in Cheongju city, in November to December of children from 13 kindergartens and September to October of from 7 kindergartens.

The overall egg positive rate was found to be 7. The 5-year age group evidenced the highest egg positive rate As compared to those reported from previous works ranged from 9. Numerous studies have suggested that eggs of intestinal nematodes, primarily Enterobius vermicularis pinwormcan serve as vectors for D. In cellophane tape samples from 64 patients with unknown D. The finding of D.


Egg positive rate of Enterobius vermicularis of primary school children in Geoje island. The status of pinworm Enterobius vermicularis egg positive rate of engerobius school children in Geoje island was investigated by using adhesive cellotape anal swap method, in September, Total egg positive rates of E.

Among three schools examined, Myeongsa primary school showed the highest egg positive rate As for the age groups, the 2nd enterobkus had the highest egg positive rate The above result led us to confirm that the egg positive rates of E. To determine whether pinworm infections and head lice infestations spread among children in orphanages, children from 4 orphanages in Busan-si and Ulsan-si, Korea, were examined for enterobiasis and head lice infestation between January and February The overall rate of Enterobius vermicularis mrofologia positivity was 0.

The rate of pinworm infection was much lower among the orphanage children compared to the rates morfoloyia in previous studies among kindergarten and primary school students. Moreover, the risk factors for enterobiasis were vermicularls frequent among these subjects than previously reported.

The personal hygiene and health of the orphanage children were supervised by a regular, employed nurse through a health education program. In conclusion, pinworm infection was efficiently controlled among the children in orphanages, and this might be related to good personal hygiene practices in Korea.

Vermicularus vermicularis in the nose: A rare case of enterobius vermicularis pin-worm is reported in the nose. An year-old girl presented with the vague symptoms of crawling sensation in the nose for few weeks, who had received treatment for allergic rhinitis. The nasal secretions were examined and confirmed the diagnosis of pinworm infection and treated by albendazole.

Hevige diarree en eosinofiele colitis toegeschreven aan aarsmaden Enterobius vermicularis.

In a year-old woman suffering from severe diarrhoea, eosinophilic infiltration of colonic mucosa and a peripheral eosinophilia, microbiological investigations only revealed large numbers of Enterobius vermicularis pinworm in the faeces. Treatment with mebendazole resulted in a rapid resolution.

New insights of Enterobius vermicularis infection among preschool children in an urban area in Malaysia. Full Text Available Enterobiasis is a common intestinal parasitic infection caused by the nematode, Enterobius vermicularis.

To assess the prevalence and to identify the underlying risk factors associated with enterobiasis among preschool children aged 1 — 6 years in Malaysia, children from four nurseries and four kindergartens residing in the urban area were examined for Enterobius vermicularis.

The cellotape anal swab technique was used for the detection of pinworm eggs.

The overall egg positive rate for Enterobius vermicularis infection was The prevalence of this infection showed an age-dependency relationship, with higher rates observed among older children, aged 5 — 6 years. Multivariate analysis confirmed that finger sucking and belonging to a large family were significant risk factors of enterobiasis in the population studied.

Recent pre-medication with anthelminthics was also found to have a significant impact on decreasing the egg positive rate for pinworm. The establishment of such data will be beneficial for the public health authorities in the planning and implementation of specific prevention in order to better control the infection.

The authors present a case of enterobiasis of the appendix. Enterobius infection is an uncommon cause of acute appendicitis. Preoperative diagnosis of pinworm infestation is almost impossible unless there is a strong clinical suspicion. Parasites may produce morfologiz which resemble acute appendicitis. Careful observation of the appendix stump may lead to intraoperative diagnosis of enterobiasis.


A quick diagnosis and appropriate treatment vemicularis prevent future complications. Although intestinal parasitic infections rarely cause acute appendicitis, they are common public health problems in undeveloped and developing countries. 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.

Herein we presented the cases of four patients with clinical findings of acute appendicitis. Patients were clinically suspected of having acute appendicitis, and Enterobius vermicularis was detected in the pathological examinations of specimens. Pinworm vermiclaris are common parasitic infections that may mimic appendicitis. The pathology of the four cases was noted when the file of patients aged between 4 and 72 years who underwent surgery for acute appendicitis in my hospital was retrospectively reviewed.

When the appendectomy specimen was examined histopathologically it was understood that acute appendicitis was caused by Enterobius vermicularis parasite.

In Enterobius infections, performing systemic therapy for patients and morfologla family members is sufficient. To prevent unnecessary appendectomy, this type of infection should be made to ask in the history and clinical findings of patients. Enterobius vermicularis and allergic conditions in Norwegian children. Studies investigating the association between Enterobius vermicularis and allergic conditions have shown conflicting results.

This study was conducted to test for any such associations in Norwegian children. Parents were asked to answer questionnaires concerning their children’s history of allergies, wheezing or eczema and pinworm infections.

Current pinworm infections were diagnosed by microscopic examination of anal scotch enterobijs samples. The data were analysed using logistic regression. No association was found between past pinworm treatments and present atopic conditions. The association between current E. A nine-year-old girl was admitted to the paediatric ward due to fever and lower abdomen morfoologia through a day.

Acute laparoscopic exploration showed a large necrotic perforation at the distal end of the appendix. During the appendectomy multiple small, live Enterobius vermicularis pinworms were observed.

The patient was admitted for three days of observation and received relevant treatment with intravenous antibiotics and antihelminthic treatment. The histology showed numerous pinworms in the lumen of the appendix and invasion of the pinworms of the submucosal layer and the wall of the appendix. Recurrent paediatric pinworm infection of the vagina as a potential reservoir for Enterobius vermicularis. Enterobius vermicularis infection remains one of the most common parasitic infections, particularly prevalent in children.

Enterobiasis, although not usually dangerous, may cause significant morbidity. Elimination of the parasite from a family or an institution often poses problems, either because of an incomplete cure or re-infection. While there have been limited reports of ectopic enterobiasis throughout the world, ours is probably one of the rarest reports of recurrent vaginal E. A 4-year-old girl presented with recurrent episodes of vulval itching on occasions over 2 years.

The vulva was inflamed with living worms, mm in length, emerging from the anterior vaginal fornix, but with no vaginal discharge. Direct microscopic examination of vaginal swabs revealed adult worms of Enterobius but no eggs. Repeated stool samples from the patient, parents and a sibling were negative. The patient was treated orally with mg of mebendazole for 3 days followed by two more courses at 3-week intervals over a period of 3 months.
