We report a case of 48-year-old woman with multiple hydatid cysts in pararectal region and right paraovarian localization with an unusual sonographic and computed tomographic presentation mimicking a pelvic endometriosis. During laparotomy, multiple pararectal and right ovarian cysts resembling endometriosis were resected. Pathologic examination gives the diagnosis of hydatid cysts. Retrospectively, we investigate the primary infection but the patient had no history of hepatic and liver involvement, it is a case of primary infection.

We present herein a case with a four-day history of fresh rectal bleeding due to leech bite. The cause was found to be a leech in the rectum by anoscope. This pathological condition is extremely rare in urban areas. Leech endoparasitism, although rare, may cause serious, even lethal, complications. Suspicion of leech infestation should be kept in mind when faced with intermittent or severe rectal bleeding in humans, and should be investigated surgically as with all other foreign bodies. In the current study, we present a patient who admitted with rectal bleeding due to leech bite. The leech was removed by hand examination (by forceps) without requiring any surgical attempt.

A 31-year-old woman from Cameroon was admitted to the University of Strasbourg Hospital in December 2007 with pelvic pain and fever that developed over three days. Her condition rapidly worsened and she underwent emergency exploratory celioscopy. Surgeons found peritoneal and retrouterine abscesses. The high rectum had a 4-cm perforation with infiltrated, friable, and irregular edges. A biopsy specimen of this pseudotumoral specimen showed many Schistosoma haematobium eggs with an inflammatory reaction surrounding the eggs. The patient was treated with praziquantel (40 mg/kg/day) for 5 days and a 4-week course of antibiotic therapy. Her progress was good and digestive continuity surgery was performed four months later. Schistosomiasis frequently involves rectal mucosa, but perforation is unusual. Our review of the literature found only two cases of colon perforation associated with S. mansoni infection. To our knowledge, this is the first case of rectal perforation caused by S. haematobium described in the literature.

We describe an unusual case of visceral Leishmaniasis affecting the gastrointestinal tract in a young immunocompetent patient whose only recent foreign travel was a trip to Mexico 9 months previously. She presented insidiously with diarrhoea, weight loss and developed subacute intestinal failure. Interestingly, she lacked most of the typical features of acute infection, including visceromegaly, fevers and hypergammaglobulinaemia. Atypical visceral involvement involving the gastrointestinal tract is well recognized in HIV coinfection, but very rare in immunocompetent patients. Repeated microscopy and culture of endoscopic biopsies failed to identify Leishmania parasites. Serological tests - direct agglutination test and anti-K39 antibody tests - were negative. This case highlights a very rare presentation of the condition with the absence of other visceral involvement and diagnosis being eventually made solely on polymerase chain reaction of rectal tissue, with a subsequent excellent response to therapy with intravenous liposomal amphotericin.

OBJECTIVE: To investigate the possible involvement of human trichomonads (Pentatrichomonas hominis and Trichomonas tenax) other than Trichomonas vaginalis in the aetiology of vaginal trichomoniasis. METHODS: Vaginal swabs taken from women attending antenatal clinics were tested for Trichomonas vaginalis by traditional assays (wet-mount microscopy and InPouch culture) and nucleic acid amplification (polymerase chain reaction). These swabs were also tested for the presence of P hominis and T tenax by nucleic acid amplification. Oral and rectal swabs from these women were tested for T tenax and P hominis respectively. Data on sociodemographic characteristics, sexual and anogenital hygiene practices likely to seed P hominis and T tenax into the vagina were collected by a questionnaire. RESULTS: 93% (161) of the 173 samples in which T vaginalis was detected by wet preparation or culture was evaluable by PCR. Of this, T vaginalis was detected in 94% (152) by T vaginalis-specific PCR. Neither P hominis nor T tenax was detected in any of the vaginal swab samples. These included nine samples for which T vaginalis had been detected by wet preparation or culture, but were negative by T vaginalis nucleic acid amplification. P hominis and T tenax were not detected in any of the rectal and oral swabs, respectively. CONCLUSION: In this group of women, there was no evidence for the involvement of trichomonads other than T vaginalis in the aetiology of vaginal trichomoniasis.

There are limited data concerning the surgical management of chronic amebic colitis (CAC) in the literature. We present our experience with 10 patients with CAC treated surgically. Patients' records were retrospectively analyzed for age, sex, duration of clinical manifestations, colonoscopic findings, the type of surgical operation, and the postoperative course. Total proctocolectomy and J-pouch construction was performed in two patients who had CAC with severe rectal involvement. Total colectomy and the Hartmann procedure was performed in eight patients with mild to moderate rectal involvement. This treatment was successful in preserving the rectum in four of the eight. Our results suggest that rectal preservation can be a reliable treatment option in patients with CAC who have mild to moderate rectal involvement. Total proctocolectomy and ileoanal anastomosis with pouch construction should be the treatment of choice for patients with CAC who have severe rectal involvement.
