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.

A commercially available agar gel diffusion (AGD) assay was used to investigate the teichoic acid antibody (TAA) response in 183 patients with proven Staphylococcus aureus (SA) infections. Two control groups were also investigated. One consisted of 100 hospitalized patients with a variety of medical and surgical conditions other than SA infection and the other consisted of 116 healthy hospital staff members. The sensitivity of the AGD assay varied markedly depending on the site of infection in the patients with proven SA infections. All patients with SA endocarditis developed positive TAA titres (greater than or equal to 1:4), although more than one third of these were initially negative. In patients with chronic osteomyelitis or septic arthritis, 41% had positive TAA titres, whereas no positive titres were detected in patients with acute osteomyelitis or septic arthritis. Lower rates of positive TAA titres were found in patients with deep abscesses (27%), pneumonia (14%) and post-operative infections (9%), but no positive titres occurred in patients with acute uncomplicated bacteremia, cellulitis or meningitis. In 100 hospitalized control patients, no positive titres were detected, and only 1 of 116 (0.9%) healthy hospital staff controls was positive. Suggested guidelines for the use of the AGD assay are discussed.

During the last few years, among nosocomial pathogens, Acinetobacter spp. have given rise to an increasing number of nosocomial infections. Acinetobacter strains are widely distributed in nature; in hospitals, the human skin is the likely source for most outbreaks of hospital infections. The organism has been frequently found in the inanimate environment, especially in moist situations and it has been isolated from various types of opportunistic infections (septicaemia, endocarditis, meningitis, pneumonia, skin and wound sepsis and urinary tract infection). For epidemiological studies, various typing methods such as biotyping, bacteriocin typing and serology have been developed. More recently electrophoretic patterns of cell-envelope proteins and plasmid analysis have proved useful in differentiating outbreak strains. Antibiogram typing may be useful but the antibiotic resistance of Acinetobacter spp. has changed rapidly within the last few years and thus antibiotyping must be complemented by other typing systems. New methods such as electrophoretic analysis of isoenzymes, definition of plasmidotype profiles or restriction endonuclease digestion of chromosomal DNA are under investigation.

Group G streptococci which have been isolated from the oral flora of rats are also normal inhabitants of the human skin, oropharynx, gastrointestinal tract, and female genital tract. This group of streptococci can cause a wide variety of clinical diseases in humans, including septicemia, pharyngitis, endocarditis, pneumonia, and meningitis. Ten days after oral gavage with 7,12-dimethylbenz[a]anthracene, 12 of 22 two-month-old, female, outbred, viral-antibody-free rats presented with red ocular and nasal discharges and marked swelling of the cervical region. Various degrees of firm, nonpitting edema in the region of the cervical lymph nodes and salivary glands as well as pale mucous membranes and dehydration were observed. Pure cultures of beta-hemolytic streptococci were obtained from the cervical lymph nodes of three rats that were necropsied. A rapid latex test system identified the isolates to have group G-specific antigen. These streptococcal isolates fermented trehalose and lactose but not sorbitol and inulin and did not hydrolize sodium hippurate or bile esculin. A Voges-Proskauer test was negative for all six isolates. Serologic tests to detect the presence of immunoglobulin G antibody to rat viral pathogens and Mycoplasma pulmonis were negative. Histopathologic changes included acute necrotizing inflammation of the cervical lymph nodes with multiple large colonies of coccoid bacteria at the perimeter of the necrotiz zone. To our knowledge, this is the first report of naturally occurring disease attributed to group G streptococci in rats.

Two hundred and seventy patients were studied during a 2 years period in Abbassia and Embaba fever hospitals. The duration of illness before admission was less than 20 days. Suggestive clinical symptoms and/or signs of each disease were stressed. Rapid laboratory investigations include slide typhoid agglutination test (98%) in enteric fevers, slide malta agglutination test (86%) in brucellosis, urine culture (100%) in urinary tract infection, gram stain of C.S.F. in bacterial meningitis (80%), encephalitis (0%) and meningeal irritation (0%), high vaginal swab culture (100%) in puerperal fevers, echocardiogram (100%) in infective endocarditis, high E.S.R. (100%) and positive C.R.P. (71%) and/or high A.S.O. (86%) in rheumatic fever, counterimmunoelectrophoresis (86%) in amoebic liver abscess, chest X-ray in pneumonia (100%), pulmonary tuberculosis (100%) and pleural effusion (100%), ultrasound of lymph nodes (100%) in tuberculous lymphadenitis. Erysipelas and tetanus were diagnosed on clinical grounds only.

Many discriminative experimental animal models of infection have been utilized in the evaluation of newer fluoroquinolones. In vivo efficacy of many of the newer agents has been shown in experimental models of meningitis, endocarditis, pneumonia, urinary tract infections, pyelonephritis, osteomyelitis, abscesses of various types, septic arthritis, gastroenteritis, salmonellosis, listeriosis, tuberculosis, syphilis, sinusitis, prostatitis and burn wound sepsis, among others. This review focuses on recent developments in a few selected areas. Although the limitations of animal model studies are well described, these results provide a rationale for the appropriate clinical usage of the newer fluoroquinolones in humans.

Fifty-two patients with moderate or severe infections associated with internal medicine were treated with imipenem/cilastatin sodium (IPM/CS) and the efficacy and the safety of this drug were evaluated. There were 20 patients with pneumonia, 10 with acute exacerbation of chronic respiratory tract infections, 9 with sepsis, 2 with pyothorax, 3 with intraabdominal infection, 2 with urinary tract infection, 1 with pulmonary abscess, 1 with infective endocarditis, 4 with fever of unknown origin. Forty-four patients were evaluable for the efficacy. Clinical efficacies were excellent in 12 patients, good in 26, fair in 3 and poor in 3. The overall clinical efficacy was 86.4%. The efficacy rate was 63.6% in patients previously treated and 93.9% in patients previously untreated with other antibiotics. Bacteriologically, Staphylococcus aureus (8 strains), Streptococcus pneumoniae (5), Streptococcus pyogenes (1), other Gram-positive coccus (1), Klebsiella pneumoniae (8), Haemophilus influenzae (4), Pseudomonas aeruginosa (3), Serratia marcescens (3), Escherichia coli (3), Branhamella catarrhalis (1), Citrobacter freundii (1), Klebsiella oxytoca (1), Enterobacter sp. (1), and Peptostreptococcus sp. (1) were eradicated. P. aeruginosa (3) and Acinetobacter sp. (1) decreased. S. aureus (1), S. epidermidis (1), P. aeruginosa (5), and S. marcescens (1) persisted or appeared. The eradication rate was 83.7%. Six patients showed adverse reactions including general fatigue 1, epigastralgia 1, eruption 1, eosinophilia 1 and elevation of S-GOT 2. But all of the adverse reactions were mild or slight, and transient. These findings indicate that IPM/CS is a useful and safe drug against bacterial infections in internal medicine.

The clinical profile of right-sided infective endocarditis in India was studied from a review of records of patients with infective endocarditis admitted to this hospital. From November 1982 to November 1989, 109 patients with infective endocarditis showed vegetations on cross-sectional echocardiography confirming the diagnosis of infective endocarditis. In 19 (17.4%) patients, only the right side of the heart was involved: specifically the tricuspid valve alone in 10; tricuspid and pulmonary valves in 4; tricuspid valve and right ventricular outflow tract in 1; tricuspid valve and right ventricular free wall in 1; pulmonary valve alone in 2; and bifurcation of pulmonary trunk in 1. Eleven patients (57.9%) had underlying congenital heart disease whereas the remaining 8 patients (42.1%) did not have any underlying heart disease. The latter group, therefore, had isolated right-sided infective endocarditis. Previous illnesses leading to isolated right-sided infective endocarditis were: puerperal sepsis in 4; septic abortion in 1; staphylococcal pneumonia in 2; and epididymoorchitis in one. Eight out of 11 patients with congenital heart disease did not report any previous illness. In the remaining 3, right-sided endocarditis followed cardiac surgery in one; dental extraction without prophylaxis in one; and pulmonary balloon valvoplasty in one. All patients with isolated right-sided infective endocarditis had features of septicaemia, but a murmur of tricuspid regurgitation was audible in only 4 (50%) of them. We conclude that, unlike western reports, the pattern of right-sided infective endocarditis in India is different. No drug addict with right-sided infective endocarditis was seen; puerperal sepsis and septic abortion were the commonest causes of isolated right-sided infective endocarditis.(ABSTRACT TRUNCATED AT 250 WORDS)
