We describe a case of Solobacterium moorei bacteremia in a 43-year-old woman presenting with acute proctitis complicating radiotherapy for cervical carcinoma. Phenotypic tests failed to identify the bacterium, which was subsequently identified by 16S rRNA gene sequencing. 16S rRNA gene sequencing could help better define the pathogenicity of S. moorei.
An 8-year-old boy developed proctitis. Rectal swabs yielded a Neisseria sp. that was repeatedly identified by API (Analytab Products, Plainview, N.Y.), Minitek (BBL Microbiology Systems, Cockeysville, Md.), and Bactec (Johnston Laboratories, Towson, Md.) methods as Neisseria gonorrhoeae. Subsequent testing in a reference laboratory yielded an identification of Neisseria cinerea. It is suggested that identification of a Neisseria sp. isolated from genital or rectal sites in a child be confirmed by additional serological, growth, and antibiotic susceptibility tests and, if necessary, by a reference laboratory. The implications of such misidentifications are discussed.
A case of proctitis and fatal septicemia caused by Plesiomonas shigelloides in a 42-year-old bisexual male is reported. The medical history of the patient was significant for an aortic valve replacement 3 years before but was otherwise unremarkable. A serum specimen obtained at autopsy was negative for antibody to human immunodeficiency virus by Western blot (immunoblot) analysis. P. shigelloides isolated from blood was susceptible to all antibiotics tested, agglutinated in Shigella group D antiserum, possessed a greater than 100-megadalton plasmid, and was noninvasive in a HeLa cell invasion assay. The previous reports of Plesiomonas bacteremic infections are reviewed, and possible pathogenic mechanisms are discussed.
The development of severe proctitis and a rectovaginal fistula two months after the onset of Behçet's syndrome in a 41 year old woman is reported.
Twenty-two patients with chronic proctitis were treated with metronidazole for 28 days in a double-blind controlled trial, but they did not appear to benefit from the drug.
Suppositories of sulphapyridine, 5-aminosalicylic acid, and placebo were used in 45 patients with idiopathic proctitis to determine the active part of sulphasalazine. Each patient used one of the suppositories twice daily for four weeks in a double-blind controlled trial. Complete clinical remission with normal rectal mucosa on sigmoidoscopy occurred in 60% of patients given 5-aminosalicylic acid, but in only 13% and 27% of those given sulphapyridine and placebo respectively. Twelve patients were included twice. In eight of these patients 5-aminosalicylic acid was given one time and sulphapyridine (two patients) or placebo (six patients) another time. Clinical remission occurred in each patient with 5-aminosalicylic acid, but in only one patient during other therapy. The results suggest that 5-aminosalicylic acid is the active therapeutic moiety of sulphasalazine.
Fifty male patients with proctitis were examined and the clinical, microbiological, serological and proctological features compared with 51 known male homosexuals attending the genitourinary (GU) clinic at the same hospital. The homosexuals had a short history of bowel symptoms, minor sigmoidoscopic and histological changes on rectal biopsy and many positive serological markers of sexually transmitted infection. There was some evidence of sexually transmitted disease in the IBD patients and three were homosexuals. IgG antibodies were positive for chlamydia trachomatis (n = 10) and hepatitis A (n = 7). One had a positive screening test for syphilis. Stool examination and rectal swab cultures were positive in two patients for cryptosporidium and cytomegalovirus respectively. Gastroenterologists must be aware of the possibility of specific infection in IBD patients and a clinical history should include sexual preferences and practices. If homosexuality is admitted, specific infection must be sought and excluded.
A male homosexual patient developed an aseptic meningitis during the course of acute ano-proctitis due to herpes simplex virus type 2 (HSV-2). Aseptic meningitis (sometimes proved to be due to HSV-2) has been associated with genital but not with anal herpes. This sexually transmissible virus should be considered when patients with aseptic meningitis are investigated.
Hydrogen peroxide is a widely available disinfectant that has been reported to cause colitis. We report a case of a 67-year-old man who presented with an acute proctitis caused by a self-inflicted 3% hydrogen peroxide enema. The patient's intention was to cure himself of a recently diagnosed prostate cancer, because the waiting list for oncological consultation was deemed too long. The pathogenesis of hydrogen peroxide mucosal injury and a review of the literature is discussed.
Reports of increased numbers of IgE-containing plasma cells in rectal biopsy specimens from patients with ulcerative colitis and non-specific proctitis have not been confirmed by others. All of these studies used conventional anti-IgE sera in immunocytochemical techniques and it is possible that the discrepancies are due to a lack of specificity of some of these reagents. A monoclonal antibody specific for human IgE was applied in this study of 23 patients. Positively stained cells were rarely found in the biopsy specimens of both the disease and normal control groups.
Follow-up studies of 2 groups of patients with idiopathic proctitis show that the survival rate is little affected by the disease. The cumulative probability of extension of the inflammation to the descending colon above the left iliac crest was about 5% at 5 years and 12% at 10 years. Corresponding figures for extension to the hepatic flexure were about 4% at 5 years and 6% at 10 years. The probability of radical surgical treatment was 3--5%.
The object of this study was to assess faecal distribution and faecal stasis in patients with ulcerative colitis and healthy control subjects and to relate the findings to the activity and extent of the disease. Each subject ingested 10 radiopaque markers daily for 13 days and attended for a plain abdominal roentgenogram on the 14th day. Patients with active ulcerative proctocolitis retained significantly fewer markers in the whole colon (median values, 11 versus 24 markers) due to a decrease of markers in the left colon (median values, 3 versus 13 markers) compared with the control group (p less than 0.05). Patients with either proctitis or colitis in remission and control subjects retained similar numbers of markers. The results of this study suggest that, as a group, patients with proctocolitis do not have proximal faecal stasis.
OBJECTIVE: To evaluate the efficacy, safety and medium-/long-term clinical course of patients undergoing endoscopic treatment with argon plasma coagulation for hemorrhagic radiation proctopathy. DESIGN: Descriptive, retrospective study with medium- and long-term follow-up. PATIENTS, MATERIAL AND METHODS: Ten patients were treated with argon plasma coagulation for hemorrhagic radiation proctopathy between July 1998 and February 2003. Inclusion criteria were: evidence of chronic rectal bleeding, consistent endoscopic findings, and absence of any other cause of hematochezia after a comprehensive ano-rectal examination and complete colonoscopy. The equipment used was a standard colonoscope, an argon delivery unit, an argon plasma coagulation probe 1.5 mm in internal diameter, and a high-frequency electrosurgical generator. Consecutive treatment sessions were programmed whenever it was considered necessary until all mucosal lesions had been treated. Clinical and evolutive follow-up was performed with a focus on tolerance, efficacy, and potential argon plasma coagulation-related complications. Data were updated by personal or telephonic interview. RESULTS: In all patients, chronic rectal bleeding stopped after the last treatment session. The mean number of treatment sessions to stop symptoms was 1.7. Mean follow-up was 31.1 months. All sessions were well tolerated, similarly to standard rectoscopy. In one case a recurrence of rectal bleeding was observed four months later, which required two repeat sessions. Four patients were anemic at inclusion. Three of them reported a resolved anemia at the end of the study. No delayed argon plasma coagulation-related complications such us ulcers or strictures were seen. CONCLUSIONS: Argon plasma coagulation appears to be a useful, effective and safe treatment for rectal bleeding resulting from chronic radiation proctitis when compared to standard medical and endoscopic treatments. These successful outcomes seem to persist even after long-term follow-up.
Oral razoxane 125 mg daily brought active Crohn's disease into remission when used alone and mainly on an out-patient basis in all nine patients studied. Remissions took several months to achieve, but no relapses have occurred on treatment and no surgery has been necessary in any of the patients. In the two patients with active non-specific proctitis, oral razoxane 125 mg daily rapidly controlled the condition. Apart from mild bone marrow toxicity in one patient, no other acute toxicity has occurred and no long-term side-effects have been observed.
A group of 1,533 homosexual males were examined in 1976 for gonorrhea at the Skin Clinic of the Boston Dispensary. This examination included a rectal culture. There were 213 males with positive rectal cultures: an infection rate of 13.7%. Of these, 173 were treated with 4 g of spectinomycin hydrochloride, intramuscularly, and 127 (73.4%) returned in one week for a posttreatment examination and culture. All who returned had a negative culture. Four grams of intramuscular spectinomycin hydrochloride appears to be effective in the treatment of gonococcal proctitis.
Proctalgia fugax is usually a source of many diagnostic and therapeutic problems. It is often very difficult to find the cause of the pain. Case-report of a 27-year-old patient who was examined by surgeons on cramp-like pain localized to the rectum. The careful history and laboratory examination confirmed gonorrheal proctitis. She was then successfully treated with ceftriaxon.
The use of high voltage radiotheraphy in pelvi malignancies has led to a common complication which is radiation . proctitis. Treatment with rectal formalin is simple and effective and can be done as a day care procedure. The use of formalin dab was assessed as a day care procedure in our surgical unit in which ten patients were prospectively evaluated. Outcome of these patients was encouraging.
In an AIDS patient who had repeated successful treatment with acyclovir in his history, erosive herpes perianalis with herpes proctitis appeared, which persisted over several weeks. High-dose intravenous administration on of acyclovir (500-750 mg, 3 x daily, over 7 weeks) did not reveal any beneficial effects: However, almost complete clearing of the lesions occurred within 3 weeks of intravenous administration of Foscarnet (50 mg/kg body wt., 3 x daily). No relapse was seen in a follow-up period of 4 months. HSV type II was isolated by culture from the erosive lesions before treatment, but no virus was found 1 week after application of Foscarnet. The unusual chronic refractory course of a severe HSV type II infection in AIDS suggests the presence of an acyclovir-resistant HSV strain in this case. This is the first observation indicating acyclovir-resistance in the Federal Republic of Germany and a warning against the unlimited use of acyclovir in AIDS patients. Foscarnet may be beneficial in some of these cases.
