Unusual infections associated with colorectal tumors may, in some instances, be the sole clue to the presence of a malignancy. The infections are either related to invasion of tissues or organs in close proximity to the tumor or secondary to distant seeding by transient bacteremia arising from necrotic tumors. Seven patients seen at one hospital over a 5-year period illustrate the clinical presentations of such infections. The infections identified in these seven patients include endocarditis, meningitis, nontraumatic gas gangrene, empyema, hepatic abscesses, retroperitoneal abscess, clostridial sepsis, and colovesical fistulae with urosepsis. A computer-assisted search of the English-language literature and cross-checks from other review articles identified other infections associated with colon cancer, which include nontraumatic crepitant cellulitis, suppurative thyroiditis, pericarditis, appendicitis, pulmonary microabscesses, septic arthritis, and fever of unknown origin. The clinical importance of these infections and their correlation with colorectal malignancies are reviewed.

Group B streptococci (GBS) have gained much attention in recent years as a cause of serious infection in the newborn. Traditionally two clinical syndromes have been defined as "early onset", with fulminant septicemia, pneumonia and meningitis, and "late onset", with a mild meningitis. More recently some previously unrecognized clinical presentations of GBS disease have been documented. These include asymptomatic bacteremia, septic arthritis, osteomyelitis, ethmoiditis with orbital cellulitis, pneumoniae with empyema, conjunctivitis. The literature to date reports 30 instances of osteomyelitis due to GBS. This report describes a forty days infant with a group B streptococcal osteomyelitis of the proximal humerus. Has been also emphasized the increased frequency and the benign clinical course of streptococcal osteomyelitis in the neonate.

The cases of seventeen children whose ages ranged from two to eighteen years and who were treated for a disorder of a sacro-iliac joint between 1975 and 1983 were reviewed retrospectively. Thirteen children were acutely ill, with a temperature of more than 38 degrees Celsius, and four had chronic symptoms that had persisted for three weeks to one year. Pain in the hip, thigh, and buttock was the most common symptom. Of the thirteen acutely ill patients, eleven had septic arthritis of a sacro-iliac joint, while one who had ankylosing spondylitis and one who had juvenile rheumatoid arthritis had acutely painful arthritis of a sacro-iliac joint. Of the four patients who had chronic symptoms, two had septic arthritis of a sacro-iliac joint; one, ankylosing spondylitis with sacro-iliac involvement; and one, eosinophilic granuloma of the ilium. Thus, thirteen patients had septic arthritis of a sacro-iliac joint and four had some other disorder. For the seventeen children who had acute or chronic symptoms, at admission the white blood-cell count ranged from 3,500 to 26,200 per cubic millimeter (average, 11,100 per cubic millimeter) and the sedimentation rate, as determined by the Westergren technique, ranged from twenty-two to sixty-five millimeters per hour (average, fifty millimeters per hour). Twelve of the plain radiographs of the seventeen patients were negative. The initial bone scans of all seventeen patients were positive in eleven and negative in six. Of these six, five had septic arthritis and one, juvenile rheumatoid arthritis. A computed tomographic scan was performed in four patients and was positive in all of them: three had septic arthritis and one had ankylosing spondylitis. Organisms were cultured successfully from blood, from material aspirated from the sacro-iliac joint, or from stool of all thirteen patients who had sepsis. The thirteen infections responded well to appropriate antibiotics, which were administered intravenously to seven patients and first intravenously and then orally to six.

A 16-year-old pony with signs of intermittent abdominal pain was treated with phenylbutazone in excess of the recommended dosage. Endoscopy revealed ulceration of the esophagus, stomach, and proximal portion of small intestine. The pony developed diarrhea. Salmonella typhimurium was isolated from the blood and feces. Treatment included fluids, trimethoprim-sulfadiazine, sucralfate, and ranitidine hydrochloride. The diarrhea resolved, as did the gastrointestinal ulceration. This case was unusual because septicemia with salmonellosis is an uncommon finding in adult equids. Also, complications commonly seen in neonatal septicemia (septic arthritis, nephritis, and hepatitis) were not observed. Phenylbutazone toxicosis and stress were considered possible causes for the gastrointestinal ulceration.

Ceftriaxone treatment (50 to 80 mg/kg once daily) was given to 201 children between 1 month and 18 years of age. There were 201 serious bacterial infections, including epiglottitis, pneumonia, cellulitis, osteomyelitis, septic arthritis, pyelonephritis, sepsis, and meningitis. The common pathogens responsible for pediatric infections isolated from these patients included Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, and Escherichia coli. The overall clinic cure rate was 94%. Ten patients were clinically improved but not cured. There were two clinical failures. Bacteriologic failure occurred in six patients. The overall bacteriologic cure rate was 97%. Twenty patients (10%) experienced adverse effects; none required discontinuation of therapy. The efficacy, safety, spectrum, and convenience of ceftriaxone monotherapy make this antimicrobial agent a candidate for the treatment of choice of selected serious pediatric infections.

Staphylococcus aureus is known to produce three very active extracellular proteinases. One of these enzymes, a cysteine proteinase, after purification to homogeneity was found to degrade insoluble bovine lung elastin at a rate comparable to human neutrophil elastase. This enzyme had no detectable activity against a range of synthetic substrates normally utilized by elastase, chymotrypsin, or trypsin-like proteinases. However, it did hydrolyze the synthetic substrate carbobenzoxy-phenylalanyl-leucyl-glutamyl-p-nitroanilide (Km = 0.5 mM, kcat = 0.16 s-1). The proteolytic activity of the cysteine proteinase was rapidly and efficiently inhibited by alpha 2-macroglobulin and also by the cysteine-specific inhibitor rat T-kininogen (Ki = 5.2 X 10(-7) M). Human kininogens, however, did not inhibit. Human plasma apparently contains other inhibitors of this enzyme, since plasma depleted of alpha 2-macroglobulin retained significant inhibitory capacity. The elastolytic activity of this S. aureus proteinase and its lack of control by human kininogens or cystatin C may explain some of the connective tissue destruction seen in bacterial infections due to this and related organisms such as may occur in septicemia, septic arthritis, and otitis.

Twenty patients were treated for septic arthritis of the knee with arthroscopic lavage (15 patients) or arthrotomy (five patients). Parenteral antibiotics were used in both groups, and both groups did well at follow-up. The advantages of arthroscopic debridement and irrigation over arthrotomy include low morbidity, minimal scarring and much earlier functional recovery (mean 10 days). The advantages over needle aspiration include complete joint visualization, lavage, and easy drain placement allowing suction-irrigation over several days, thus avoiding multiple aspirations. Arthroscopic treatment of knee sepsis in children is simple to perform, is associated with minimal morbidity, and affords excellent long-term results.

Two cases of coexisting septic and crystalline joint disease are reported. In one patient polyarticular septic arthritis occurred simultaneously with gout and pseudogout. In a second patient septic arthritis preceded the appearance of calcium pyrophosphate dihydrate (CPPD) crystals in the joint fluid, supporting an earlier postulate that lysosomal enzymes released during sepsis lead to shedding of crystals from cartilage and synovium into the joint space. This sequence was demonstrated in a rat air pouch model of synovium, in which CPPD crystals embedded in facsimile synovial tissue were released after injection of pyogenic bacteria. Coexisting septic arthritis should always be considered when crystals are identified in inflamed joints, particularly in elderly patients with concurrent infections.

The antibacterial efficacy of some of the newer quinolone antimicrobial agents in general, and ciprofloxacin in particular, in animal models of experimental septic arthritis, burn wound sepsis, empyema, chronic gastroenteritis, granuloma pouch infection, intraabdominal abscess, osteomyelitis, prostatis, sinusitis, urinary tract infection, and severe septicemia caused by Pseudomonas aeruginosa is reviewed. In addition, the efficacy of these newer quinolones has been studied in animal models of pneumonia, endocarditis, meningitis, skin and soft tissue infections, and a variety of other systemic infections. Although certain limitations are associated with animal models of infection, properly performed studies clearly have the potential to provide guidelines for evaluating the efficacy of antimicrobial agents in the treatment of some infections in humans.

Three unrelated severe infections with Streptococcus zooepidemicus occurred in England in 1985. The first patient developed septic arthritis, which has not been recorded before with this organism. The second died with septicaemia, pneumonia and post-streptococcal glomerulonephritis, the only record so far of nephritis following sporadic S. zooepidemicus infection and of nephritis and systemic sepsis in the same patient. The third patient experienced septicaemia during pregnancy but recovered without complications. A likely animal source of infection was found in only one case.
