A 10-year study of homosexually transmitted infection.

A 10-year survey is presented of male cases of homosexually acquired infection seen between 1962 and 1971 at Charing Cross Hospital (West London Branch). Tables showing the number of cases of syphilis, gonorrhea, and other conditions in homosexual and heterosexual males and in females are considered. Tables of other relevant data are also presented. The reasons underlying the changes illustrated, including the Act legalizing homosexual practices between consenting adult males, which became effective in 1968, are discussed. Certain pathological conditions apparently connected with homosexual practices, such as serum hepatitis, local rectal disease, and mucous colitis, are included and also some relevant manifestations of herpes genitalis and genitral warts. Homosexually acquired infection in prisoners is described. Some of the psychiatric effects of homosexuality on clinic patients and also their fears of treatment at clinics are considered, as well as the behavioral differences in response to infection between exclusively homosexuals, bi-sexuals, and married homosexuals.

The effect of prednisone and irradiation on the rectum in dogs.

In an attempt to diminish the severity of the acute and late effects of irradiation to the rectum of dogs, oral prednisone was administered to 10 dogs for 1 week prior to, during, and for 1 month following a 3-week fractionated course of 60Co exposures to the pelvis. A control group of 10 dogs received irradiation alone. The dogs were observed clinically, serial rectal biopsies were done during and following the acute reaction, and the rectum was studied following sacrifice. Observations suggest that prednisone has no beneficial effect on the acute inflammatory reaction, and increases the severity of the late tissue damage.

Perirectal inflammatory disease: CT findings.

The findings on computed tomographic (CT) scans were reviewed in 42 patients with perirectal inflammatory disease and suspected perirectal abscesses. CT was reliable for use in distinguishing perirectal abscesses from cellulitis and in localizing both supralevator and infralevator abscesses. CT allowed correct diagnosis of 13 surgically proved perirectal abscesses in ten patients, including three with residual abscesses after surgical drainage. In three patients with supralevator abscesses, the abscess was missed on initial surgical exploration. In patients without abscesses, CT was helpful in evaluating the extent of perirectal inflammation; however, it was not possible to determine its cause. The anatomy on CT scans of the pararectal spaces is reviewed, with emphasis on useful anatomic landmarks in the axial plane for distinguishing supralevator from infralevator abscesses.

Inflammation enhances reflex and spinal neuron responses to noxious visceral stimulation in rats.

To improve understanding of sensory processes related to visceral inflammation, the effect of turpentine-induced inflammation on reflex (cardiovascular/visceromotor) and extracellularly recorded lumbosacral dorsal horn neuron responses to colorectal distension (CRD) was investigated. A 25% solution of turpentine, applied to the colorectal mucosa, produced inflammation, decreased compliance of the colonic wall, and enhanced reflex responses in unanesthetized rats within 2-6 h. At 24 h posttreatment, pressor responses to CRD (80 mmHg, 20 s) were 20% greater, and intraluminal pressures needed to evoke visceromotor reflexes were 30% lower than controls. Parallel electrophysiological experiments in spinal cord-transected, decerebrate rats demonstrated that two neuronal subgroups excited by CRD were differentially affected by turpentine administered 24 h before testing. During CRD, abrupt neurons were 70% less active and sustained neurons were 25% more active than similar neurons in controls. In summary, reflex and neuronal subgroup (sustained neurons) responses to CRD were both potentiated by chemical inflammation. This suggests that the neurophysiological basis for inflammation-induced increases in reflex responses to CRD is increased activity of this neuronal subgroup.

Solitary microcarcinoid of the rectal stump in ulcerative colitis.

A case of solitary microcarcinoid and chronic ulcerative colitis of the rectal stump is described. The association of intestinal carcinoid with ulcerative colitis has been reported previously in 26 patients. Pathogenic pathways are discussed according to the presence of multifocal carcinoid and/or gut endocrine cell hyperplasia.

Paclitaxel-carboplatin induced radiation recall colitis.

Some chemotherapeutic agents can "recall" the irradiated volumes by skin or pulmonary reactions in cancer patients who previously received radiation therapy. We report a recall colitis following the administration of paclitaxel-containing regimen in a patient who had been irradiated for a carcinoma of the uterine cervix. A 63-year-old woman underwent a Wertheim operation because of uterine cervix carcinoma. After 8 years of follow-up, a local recurrence was observed and she received curative external radiotherapy (45 Gy) to the pelvis. No significant adverse events were observed during the radiotherapy. Approximately one year later, she was hospitalized because of metastatic disease with multiple pulmonary nodules, and a chemotherapy regimen consisting of paclitaxel and carboplatin was administered. The day after the administration of chemotherapy the patient had diarrhea and rectal bleeding. Histological examination of the biopsy taken from rectal hyperemic lesions showed a radiation colitis. The symptoms reappeared after the administration of each course of chemotherapy and continued until the death of the patient despite the interruption of the chemotherapy. In conclusion, the probability of recall phenomena should be kept in mind in patients who received previously with pelvic radiotherapy and treated later with cytotoxic chemotherapy.

Intracellular Campylobacter-like organisms associated with rectal prolapse and proliferative enteroproctitis in emus (Dromaius novaehollandiae).

Rectal prolapse was the presenting clinical finding in a group of juvenile emus (Dromaius novaehollandiae). Gross findings included severely thickened and rugose distal rectal mucosae. Histologically, there were thickened villi, enterocyte hyperplasia, dilated glands filled with mucus and heterophils, and a dense infiltrate of heterophils, macrophages, lymphocytes, and plasma cells in the lamina propria. Examination of Warthin-Starry silver-stained sections revealed numerous apically located comma-shaped intracytoplasmic bacteria approximately 1 x 3 microns in size. Campylobacter-like organisms morphologically compatible with ileal symbiont intracellularis now known as Lawsonia intracellularis were seen via electron microscopy. Bacteria were further characterized by indirect immunofluorescence using monoclonal antibody specific for the 25-27-kd outer membrane protein of L. intracellularis.
