A case of Listeria monocytogenes endocarditis occurring as a complication of a vascular access infection in a patient on chronic hemodialysis that was successfully treated with a combination of vancomycin and gentamicin is reported. The difficulties in the diagnosis and treatment of L. monocytogenes infections, especially endocarditis, in patients on chronic hemodialysis are discussed.

A prospective, randomized study was carried out to evaluate two antibiotic prophylactic regimens for patients undergoing cardiac surgery with cardiopulmonary bypass. Each patient of the first group (cefazolin) received four intravenous injections of 1 g cefazolin during 12 hours, patients of second (cefamandole), four doses of 750 mg. 155 patients scheduled for cardiac operation were included in the study. (May 1983 to April 1984). Patients were not admitted to the study in case of emergency, if their weight was less than 20 kg, if they had received antibiotics during the week before surgery or if they had a history of anaphylactic reactions to cephalosporins. There were no differences between the two groups on age, weight, height, sex, previous history of infectious disease, surgery and intensive care. There were no significant differences between the two groups in minor infections. The rate of urinary tract infection by streptococci was significatively higher (p less than 0.02) in the cefamandole group (38.3%) than in the cefazolin group (17.6%). There were no major infections (septicemia, mediastinitis, endocarditis). Patients temperature was the same during the first four postoperative days. Hospital stay was the similar in the two groups. The two antibiotics are similarly effective to prevent major infections in cardiac surgery. However cefazolin was preferred for antibiotic prophylaxis in cardiac surgery because of the higher rate of streptococcal urinary infections in patients given cefamandole.

Fungal endocarditis is caused by fungi Candida and Aspergillus. Continuous intravenous infusions, catheterization, open-heart surgery, tracheal injuries, artificial heart valves can serve as predisposing factors. Aspergillus endocarditis is more common in severe infectious diseases after a prolonged use of antibiotics, cytostatics, glucocorticoids. A case of aspergillus endocarditis of mitral and tricuspid valves is described in a 55-year old patient. The man had been long suffering from silicotuberculosis and had been on a prolonged antibacterial therapy. The aspergillus endocarditis must have developed in the patient due to marked dysbacteriosis.

In a retrospective study covering a 13-year period and a population of 817,900 inhabitants, 13 cases of invasive infection caused by Haemophilus species other than Haemophilus influenzae were found. Ten of the infectious episodes were caused by Haemophilus parainfluenzae and three by Haemophilus aphrophilus. The clinical manifestations comprised endocarditis, meningitis, pleuropneumonia, epiglottitis and septicaemia from an unknown focus. These 13 infectious episodes caused by uncommon Haemophilus species constituted less than 3% of the total number (473) of invasive Haemophilus infections registered during the same period of time. Invasive H. influenzae infections were more common in all age groups than infections caused by other Haemophilus species. In contrast to H. influenzae infections, which predominate in childhood, invasive infections due to uncommon Haemophilus species had no predilection for any age group.

Infection is a major complication of pacemaker treatment. Antibiotic prophylaxis has been used in association with pacemaker surgery with conflicting results, and conclusive prospective trials are lacking. This investigation indicated that systemic antibiotic prophylaxis was of benefit when infections occurred frequently. The effect of local antibiotic prophylaxis was comparable with that of systemic prophylaxis at generator replacements. No serious adverse effects of the prophylaxis were noted. However, with modern surgical methods and hygienic principles, antibiotic prophylaxis did not seem to be necessary at implantation of new cardiac pacemakers. Once infection had developed it was difficult to eradicate and serious complications sometimes occurred. Most infections commenced in the pacemaker pocket. A few cases were cured by antibiotic treatment alone but, particularly if the infection spread along the electrode, surgery was strongly needed and in the presence of endocarditis and/or septicemia all foreign material should be removed if possible. The most common causal microorganisms of pacemaker infections were Staphylococcus aureus and Staphylococcus epidermidis. Routinely performed pre-, per- and postoperative cultures were of no prognostic value. Persistent use of antibiotics could select for methicillin-resistant coagulase-negative staphylococci, therefore bacteriological monitoring of wound infections was considered important. The dosage schedules used for cloxacillin and flucloxacillin gave satisfactory serum concentrations peroperatively. Local treatment with cloxacillin in the pacemaker pocket peroperatively gave adequate concentrations in tissue fluid from the pocket 24 h after the operation, as did systemic administration of flucloxacillin. The pharmacokinetics of flucloxacillin in these elderly patients differed in some respects from that found in healthy volunteers. Plasma elimination half-life was almost twice as long. Despite the high degree of plasma protein binding, flucloxacillin appeared to pass rapidly and efficiently to extravascular compartments, such as a pacemaker pocket.

The field of infectious diseases covers many entities that can be considered true medical emergencies. Included are meningitis, brain abscess, spinal epidural abscess, epiglottitis, pneumonia, bacteremia, endocarditis, certain intraabdominal infections, gas gangrene, and necrotizing fasciitis. Because emergencies related to infectious agents are potentially the most readily reversible of all medical emergencies, it behooves us to diagnose them as rapidly and specifically as possible so that appropriate life-saving therapy may be begun expeditiously. This article reviews and summarizes the presentations of others in this issue and presents views on future prospects in the rapid diagnosis of infectious diseases.

We reviewed infectious complications during 7,671 days of central venous (Hickman) catheter use in 47 patients receiving intensive cytotoxic and supportive therapy for malignant disease. Colonization of the catheter was identified in eight cases of septicemia, two associated with endocarditis. Septicemia was successfully treated in four of five patients after removal of the catheter and in two of three in whom the catheter remained in situ. Infection of the exit site occurred in five patients but in only one was there associated septicemia. Poor patient compliance with the recommended regimen for catheter care was suspected. Thus, the overall rate of catheter-related infection was 1.6 per 1,000 days. Guidelines are discussed for removal of the catheter for suspected catheter-related infection.

We have reviewed 107 cases of staphylococcal bacteraemia in order to assess the current clinical spectrum of serious staphylococcal sepsis in Zimbabwe, where staphylococcal bacteraemia is common. Infection was hospital-acquired in 35 cases and community-acquired in 72 cases. The mortality rate was 28%. Most patients were young, with predisposing conditions such as prematurity, protein-caloric malnutrition and measles. The length of the prodromal illness tended to be short and a primary site of infection, usually the lungs or skin, was obvious in 66% of patients. In 30% there was evidence of metastatic spread, usually to meninges, bone, joint and muscle, but endocarditis was uncommon. Metastatic infection was rare when infection was acquired in hospital. Death appeared to be associated with measles, protein-caloric malnutrition, acquisition of infection in hospital, absence of an obvious focus of infection and with inappropriate antibiotic therapy. Aggressive treatment with antibiotics intravenously was the rule. A combination of penicillin and an aminoglycoside was favoured until the nature of the infecting organism was established. Of those patients who died, 38% had received less than 72 h antibiotic therapy. Multiple antibiotic resistance is now widespread in Zimbabwe.

We studied the activity of cefotaxime both microbiologically and clinically. 138 blood cultures positive for gram-positive cocci were evaluated (90 strains of Staphylococcus aureus, 25 of Streptococcus faecalis, 13 of Streptococcus alpha and ten of Streptococcus mutans). Cefotaxime showed good activity against all strains with the exception of S. mutans, of which only 30% were sensitive. Ten cases of gram-positive infections were studied clinically: six sepsis cases and one endocarditis case due to S. aureus, two sepsis cases caused by Streptococcus alpha and one Enterococcus endocarditis case. Therapy was successful in nine; the S. aureus endocarditis failed. The local and general tolerance of cefotaxime was good.

Staphylococcus aureus strains were exposed in vitro to continuously decreasing cefotaxime concentrations. The initial concentration was approximately 4 X MIC and decreased at t1/2 = 60 min. A reduction in the colony count was seen even after the concentration had dropped below the MIC level. Sixteen patients with blood cultures positive for S. aureus were treated with cefotaxime. Four patient died of underlying diseases. The condition of one patient with staphylococcal endocarditis under treatment with vancomycin in combination with cefotaxime deteriorated when cefotaxime was discontinued, suggesting possible synergism between these two drugs against staphylococci.
