Enterobius vermicularis Infection with Tuboovarian Abscess and Peritonitis Occurring during Pregnancy
ABSTRACT Extraintestinal Enterobius vermicularis infections are rare but may occasionally affect the female genital tract. Although mostly asymptomatic or causing minor clinical problems, they may lead to severe infectious complications.
Case report and review of the pertinent English language literature.
A 31-year-old, 30-week-pregnant female was admitted with a clinical suspicion of appendicitis. At surgery, the appendix appeared normal, but generalized peritonitis of unclear origin was present. Eggs of Enterobius vermicularis were found upon microbiological and pathological examination. Because of persisting infectious disease, the patient underwent an elective caesarean section, and at that time the diagnosis of a right tuboovarian abscess was made, and salpingo-oophorectomy was performed. The pathology report confirmed the diagnosis of an E. vermicularis salpingo-oophoritis.
This case was extraordinary because of a combination of tuboovarian abscess and generalized peritonitis with E. vermicularis infection occurring during late pregnancy. Ectopic enterobiasis should be considered in the differential diagnosis of pelvic infections of gynecological origin.

ABSTRACT: The aim of this study was to evaluate the sole effect of sperm concentration on fertilization, embryo quality and pregnancy rates in patients undergoing ICSI cycles. 560 ICSI cycles performed for male factor infertility were divided into four groups according to sperm concentration retrospectively. Group 1 consisted of 86 couples whose sperm concentration was less than 1x10(6), group 2 consisted of 169 couples whose sperm concentration ranged between 1x10(6) and 5x10(6), group 3 consisted of 95 couples whose sperm concentration ranged between 5x10(6) and 10x10(6) and group 4 consisted of 210 couples whose sperm concentration ranged between 10x10(6) and 20x10(6). Fertilization rate was significantly lower in the first three groups compared to the last group (p<0.05). The first three groups were comparable with each other. There were no differences according to ovarian response to stimulation, embryo quality and clinical pregnancy rates between the four groups. Lower sperm concentration has detrimental effects on the outcomes of ICSI cycles. This situation is more evident in men with severe and extremely severe oligozoospermia.Clinical and experimental obstetrics & gynecology 01/2012; 39(3):280-2. · 0.36 Impact Factor

ABSTRACT: We report a rare and unusual case of invasive Enterobius vermicularis infection in a fallopian tube. The patient is a 23-year-old woman from Malaysia who presented with suprapubic pain and vaginal bleeding. A clinical diagnosis of ruptured right ovarian ectopic pregnancy was made. She underwent a laparotomy with a right salpingo-oophorectomy. Histopathological examination of the right fallopian tube showed eggs and adult remnants of E. vermicularis and was confirmed using PCR and DNA sequencing.Journal of Clinical Microbiology 07/2014; 52(9).

ABSTRACT: We genetically characterized pinworms obtained from 37 children from different regions of Germany and established new species-specific molecular diagnostic tools. No ribosomal DNA diversity was found; the phylogenetic position of Enterobius vermicularis within the Oxyurida order and its close relationship to the Ascaridida and Spirurida orders was confirmed.Journal of clinical microbiology 04/2011; 49(4):1602-4.
