The common infective conditions encountered at King Khalid Teaching Hospital, Riyadh, Saudi Arabia were described. These data were collected mostly during a period of 8 years between 1981 to 1988. These infections included brucellosis, cholecystitis, conjunctivitis, enteric fever, gastroenteritis, infective endocarditis, meningitis, otitis media, pneumonia, septicaemia, sorethroat, treponemal infections, urethritis, urinary tract infections, and vaginitis. A scheme for empiric chemotherapy has been suggested for these infections based on the sensitivity results obtained mostly from the microbiology laboratory at Teaching Hospital, Riyadh. This scheme of empiric therapy is offered as a guide only. It does not cover all possibilities and is not intended as a rigid dogma. Empiric therapy has also been suggested for some other infective conditions where sufficient data were not available from the Teaching Hospital. Empiric therapy should be started after relevant specimens are collected. Culture and sensitivity tests are invaluable in the management of patients with infectious diseases. As soon as sensitivities of the infecting organisms' are known, treatment should be adjusted accordingly. In some cases, Gram-staining is valuable to guide the initial therapy (eg. meningitis, pneumonia, and urethritis). Finally, close liaison between physicians and clinical microbiologists is mandatory for successful therapy.

Reiter's syndrome is a chronic rheumatic disease that develops after infective urethritis or gastroenteritis and has a strong association with the HLA-B27 antigen. How these factors interact remains unclear. We present a patient with Reiter's syndrome who exhibited 2 novel features: unusually severe urethritis that produced strictures requiring surgery, and dramatic regression of his rheumatic manifestations following a urethrectomy.

Reactive arthritis (ReA) is an inflammatory arthritis which follows either chlamydia-induced non-specific urethritis or gastroenteritis due to yersinia, salmonella, shigella or campylobacter. It is distinguished from other infection-induced arthritides by its association with the MHC class I antigen HLA-B27, the pattern of arthritis (a lower-limb oligoarthritis often associated with sacroiliitis) and its systemic features (conjunctivitis, circinate balanitis and skin rash). ReA is unique among inflammatory arthritides in the clear definition of its trigger, its onset, its HLA association, and the demonstrating of a triggering antigen-specific cell-mediated immune response in the joint. Clear delineation of these factors makes it possible to test pathogenetic hypotheses which cannot be analysed in other more common forms of arthritis. However, since there are many similarities between these and ReA, the mechanisms established in ReA may have general relevance in understanding synovitis.

Reactive arthritis (ReA) is an inflammatory arthritis triggered by infection, usually urethritis or gastroenteritis, and is strongly associated with the MHC class I antigen HLA-B27. Two recent observations have excited interest: first, antigen and DNA from the triggering bacteria have been identified in the joint and, second, ReA synovial T cells have been found to respond specifically to the bacterium that caused the initiating infection. Because the trigger of ReA, its onset and the MHC association are all clearly defined, we can investigate hypotheses that are impossible to study in other forms of human arthritis. Here, Gabrielle Kingsley and Jochen Sieper review the topic in the light of a recent workshop.

Adenoviruses (Ads) are an important cause of respiratory illness, conjunctivitis, and gastroenteritis, but they are seldom recognized as a potential cause of sexually transmitted disease. We performed virus cultures on approximately 7,000 patients attending a sexually transmitted disease clinic or other health department clinics for the evaluation of genital ulcers, urethritis, or conjunctivitis. Ads were isolated from genital or conjunctival specimens obtained from 23 (0.33%) patients. Among the 20 Ad-positive men, 15 (75%) had urethritis, 12 (60%) had conjunctivitis, and 10 (50%) had both. All three Ad-positive women had vaginal discharge and genital ulcers or fissures. Ad isolates from 17 patients were available for serotyping. Ad type 37 was isolated from 14 patients, Ad type 8 was isolated from 2 patients, and Ad type 2 was isolated from 1 patient. In three of the Ad type 37 cases, Ad was recovered from both urethral and conjunctival specimens. One of the Ad type 8 cases had conjunctivitis, but the Ad type 2 case did not. Ads, particularly type 37, may be a sexually transmissible cause of genital ulcers, urethritis, and conjunctivitis.

A general consensus supports fundamental roles for both genetic and environmental, mainly microbial, factors in the development of autoimmune diseases. One form of autoimmune rheumatic diseases is confined to a group of nonpyogenic conditions which are usually preceded by or associated with either explicit or occult infections. A previous history of clinical pharyngitis, gastroenteritis/urethritis, or tick-borne skin manifestation can be obtained from patients with rheumatic fever, reactive arthritis, or Lyme disease, respectively, whilst, other rheumatic diseases like rheumatoid arthritis (RA), ankylosing spondylitis (AS), and Crohn's disease (CD) are usually lacking such an association with a noticeable microbial infection. A great amount of data supports the notion that RA is most likely caused by Proteus asymptomatic urinary tract infections, whilst AS and CD are caused by subclinical bowel infections with Klebsiella microbes. Molecular mimicry is the main pathogenetic mechanism that can explain these forms of microbe-disease associations, where the causative microbes can initiate the disease with consequent productions of antibacterial and crossreactive autoantibodies which have a great impact in the propagation and the development of these diseases.

In Afghanistan in mid June 2011, 2 US Marines developed reactive arthritis manifested by conjunctivitis, urethritis, arthritis, and circinate balanitis. Their symptoms were preceded by an outbreak in their unit of gastroenteritis caused by Shigella species after ingesting contaminated chicken. Gastroenteritis has plagued military operations for millennia. This report emphasizes that personnel can develop reactive arthritis after bouts of gastrointestinal infections that are common in deployed environments. It is highly recommended to maintain vigilance in keeping reactive arthritis on the differential diagnosis in deployed personnel after bouts of gastroenteritis.
