The purpose of this paper is to highlight the incidence and scope of lower gastrointestinal tract (GIT) diseases in the Eastern Province of the Kingdom of Saudi Arabia. Between August 1981 and April 1984, 288 patients with significant complaints and physical signs attributable to the lower GIT were prospectively evaluated. A complete patient history was taken in each case followed by physical examination, routine laboratory studies and a sigmoidoscopic examination. In 128 patients (44.5%), sigmoidoscopy and rectal and/or colonic biopsies did not reveal any pathological abnormalities. These patients were considered to have various disorders such as irritable bowel syndrome or parasitic infestation. Eighty-one patients (28%) were found to have mild to moderate non-specific colitis or proctitis. In another 49 patients (17%) the diagnosis of schistosomiasis mansoni was made. Ulcerative colitis and colorectal carcinoma were detected in only 11 (4%) and 4 (1.5%) patients respectively. In the remaining 15 patients (5%), other lower GIT diseases were found. Comparative analysis of the disease pattern in our series has demonstrated some differences from other series from within the Kingdom and also from other countries.

Strongyloidiasis is a tenacious soil-transmitted nematode infestation endemic in the south-eastern United States. Thirty-three cases were diagnosed in a series of 1,290 stool examinations in 971 patients at Veterans Administration Medical Center, Mountain Home, Tennessee. Most patients had a concurrent major illness, such as chronic lung disease, serious bacterial infection, or cancer. A minority presented with gastrointestinal symptoms alone. Skin rash was uncommon. Eosinophilia, IgE elevation, and skin anergy were common. Atypical presentations included severe proctitis, colitis, and exacerbation of inflammatory bowel disease. In a patient with the hyperinfection syndrome, the diagnosis was made only at autopsy. Since strongyloidiasis seems to present like an opportunistic illness, all physicians, not just those in endemic areas, should consider its presence in the appropriate setting.

Certain enteric ailments are particularly common among homosexual men. They are primarily infectious diseases and include not only such common venereal diseases as gonorrhea and syphilis but also infections not usually regarded as being sexually transmitted. Among the latter are shigellosis, salmonellosis, giardiasis, and amebiasis. Patients' symptoms are non-specific and seldom helpful in diagnosing particular diseases. The practitioner must be prepared to identify a number of infections with similar presentations that may occur singly or together in gay men. Gonorrhea is probably the most common bacterial infection in gay men. Carriage rates as high as 50% have been reported, and extra-genital carriage is common; this necessitates culturing the urethra, rectum, and pharynx. Procaine penicillin G is the treatment of choice for most patients; spectinomycin is probably the drug of choice in penicillin-sensitive patients. In contrast to other venereal diseases, syphilis may have a characteristic protoscopic presentation. Benzathine penicillin G is the treatment of choice for most patients. Lymphogranuloma venereum causes penile lesions and inguinal lymphadenitis in heterosexual men, whereas homosexual men are more prone to proctitis. The disease may mimic Crohn's disease. Recommended treatment includes tetracycline or sulfamethoxazole-trimethoprim. Shigellosis usually presents as an acute diarrheal illness. Patients generally require only supportive treatment with fluids. Herpes simplex viral infection is difficult to diagnose and has several different presentations, including lumbosacral radiculomyelopathy. Symptomatic treatment with sitz baths, anesthetic ointment, and analgesics is recommended. Venereal warts are believed to be caused by the same virus that causes verrucous warts; they are usually found in the anal canal or around the anal orifice. They are commonly treated with 25% podophyllin solution. Parasitic infections include giardiasis, amebiasis, and pinworm infections. Metronidazole may be used in the treatment of symptomatic giardiasis and amebiasis, but it is not approved for the former indication; quinacrine is approved for giardiasis. Pinworm infestation may be treated with pyrantel pamoate or mebendazole. Cure of enteric diseases in homosexual men must be documented.

Intestinal spirochetosis (IS) is an infestation defined by the presence of spirochetes on the surface of the colonic mucosa. The implicated organisms can be Brachyspiraaalborgior Brachyspirapilosicoli. We present the case of a 66-year-old man with a past medical history of diabetes mellitus, hypertension, morbid obesity, and gastroesophageal reflux. The patient was sent to the gastroenterology clinic for a screening colonoscopy due to a prior history of colonic polyps. The patient was completely asymptomatic as he denies any abdominal pain, diarrhea, melena, or hematochezia. A colonoscopy was done showing colitis in the cecum and at the ileocecal valve, for which random biopsies were taken in the terminal ileum, cecum, and ascending colon. The histopathology result was positive for spirochetosis. Due to this finding, the patient was referred to the infectious diseases clinic, where a rapid plasma reagin (RPR) and human immunodeficiency virus (HIV) tests were found to be negative. Since the patient was immunocompetent and asymptomatic, it was decided to monitor and not initiate antibiotic treatment. Human IS are not related to non-intestinal spirochetes like Treponema pallidum. An infection of T. pallidum leads to a malignant picture called syphilitic proctitis and appears in the setting of an immunocompromised patient. The treatment of IS is based on the clinical presentation, severity of symptoms, and immune status. The purpose of this case is to emphasize the correct antibiotic indication in patients with IS.
