We have reviewed the clinical presentation of pneumonia to the Goroka paediatric ward. In comparison to survivors, children dying from pneumonia more often (p less than 0.05) had malnutrition (weight-for-age under 80%), anaemia (haemoglobin under 9g%), and a marked leucocytosis (total white cell count over 30,000 cells per c.m.m.). Children dying from pneumonia had been ill for longer and had been given more antibiotics prior to admission. There was no significant difference between children dying from pneumonia and survivors in age distribution, pulse rate, incidence of cardiac failure or duration of stay in hospital. 70% of the children dying from pneumonia at Goroka Hospital are infants under 12 months of age. Pneumococcal vaccine gives a poor antibody response in infants, and overseas studies using lung aspiration suggest that Haemophilus influenzae and Staphylococcus aureus might be causative organisms as well as Streptococcus pneumoniae. A study to determine the aetiology of pneumonia in Highlands children is required to enable a rational choice of routine antibiotic therapy and to plan further research on vaccination against pneumonia.

A 65 year old man developed endocarditis and septicemia due to Hemophilus aphrophilus, a Gram-negative coccobacillus. Renal rather than cardiac failure was the principal feature of his illness and renal biopsy was compatible with glomerulonephritis secondary to septicemia. Rapid recovery of renal function and improvement of the glomerular lesion followed antibiotic treatment of the septicemia. This case illustrates the renal damage that can occur in association with septicemia due to rarer infectious agents. As with more common organisms, specific antimicrobial therapy leads to rapid improvement of the nephropathy.

During a four-year surveillance period in a tertiary care children's hospital, nine children experienced 11 episodes of Haemophilus influenzae non-type b invasive infections, representing 9% of all invasive H influenzae infections. Of these nine children, two had lymphoproliferative disorders; one had immunoglobulin subclass deficiency; one had severe congenital heart disease, with chronic heart failure; two had cerebrospinal fluid leaks; and two were premature neonates whose mothers had prolonged rupture of amniotic membranes. Only one child had no evidence of an underlying condition that might predispose him to infection with these ordinarily nonpathogenic organisms. Three of the isolates were serotype f, one was serotype e, and the remaining seven were nontypable, with types a through f antisera. Thus, the majority of children experiencing invasive H influenzae non-type b infections appear to have a predisposing medical condition. To aid in detecting these unusual infections, all H influenzae isolates from otherwise sterile body sites should be serotyped, and those children with non-type b isolates should be evaluated for a possible predisposing underlying illness.

Sputum specimens were received for microbiological examination from 110 patients following open heart surgery. The isolation of Haemophilus influenzae occurred significantly more often in those patients who had pre-existing chest disease, but was not associated with postoperative chest problems. There was a significant association between pre-operative heart failure and subsequent severe pulmonary complications.

Haemophilus aphrophilus was isolated from the blood of a 31-year-old man with subacute bacterial endocarditis. Subsequently the patient died with acute tubular necrosis of the kidney, probably secondary to cardiac failure. The characteristics of the species are described and pathogenicity to mice is reported for the first time.

Gram negative bacilli endocarditis are unfrequent. Nevertheless we encountered 28 cases of them (8.8%) among 320 endocarditis of which 10 were primitive and 7 cases (10.9%) among 65 prosthetic endocarditis. Bacterial species were 12 Pseudomonas aeruginosa, 2 Ps, stutzeri, 1 Ps. maltophilia, 2 Klebsiella pneumoniae, 2 Escherichia coli, 3 Serratia marcescans, 1 Enterobacter cloacae, 1 Brucella, 1 Hemophilus aphrophilus, 1 Fusobacterium funduliformis, 18 cases were hospital acquired infections related to cardiac surgery (4 cases), intracardiac catheterization (5 cases), intravenous catheter (4 cases). Uncontrolled infection or cardiac insufficiency underwent respectively in 14 and 18 cases. The overall mortality was 50 p. cent. The death occurred more frequently in primitive endocarditis (70%) than in secondary native endocarditis (45%) or prosthetic endocarditis (29%). It was also more frequent in Pseudomonas endocarditis (59%) than with other species (36%) and more frequent when cardiac sufficiency was present (50%). 15 patients underwent surgical procedure of which 6 died (40%). The results were better if the infection was cured before surgical procedures: 5 deaths occurred when the culture of the valves remained positive (9 cases) but none when it was negative. The 5 most recent cases of prosthetic endocarditis were cured. Since 1979, no death occurred among treated patients. we concluded that surgery is usually necessary but after an effective antibiotic therapy over a 4 or 6 week period.

Complications of infective endocarditis may be considered as those that involve the heart and adjacent structures or those that are extracardiac. Congestive heart failure is the most common serious complication of infective endocarditis and is the leading cause of death among patients with this infection. In patients with severe heart failure unresponsive to medical therapy after 24 to 48 hours, prompt cardiac valve replacement should be considered, irrespective of the duration of preoperative antimicrobial therapy. We believe that all patients with bacterial infective endocarditis who are stable hemodynamically and who have not had multiple large emboli should receive at least one course of antimicrobial therapy in an attempt to sterilize the infected valve before cardiac valve replacement is considered. Most patients with multiple major embolic events should undergo cardiac valve replacement or debridement of the infected valve. The technical limitations and the experience with two-dimensional echocardiography in patients with infective endocarditis who have valve vegetations demonstrated by echocardiography are not yet sufficient to justify cardiac valve replacement solely on the basis of echocardiographic findings. The highest frequency of major embolic events occurs in association with infections that produce large mobile valve vegetations, such as those caused by Haemophilus parainfluenzae and other slow-growing fastidious gram-negative bacilli, fungi (especially Aspergillus), and nutritionally variant viridans streptococci.

6 cases of endocarditis and 1 of septicemia caused by Haemophilus parainfluenzae have been observed in our hospital from 1970 to 1977, as against no case from 1957 to 1969. The mean age of the patients was 46 years. The clinical picture did not differ from that seen in cases of septicemia and endocarditis from other cases. In 4 cases no underlying heart disease was known. In 2 of them, endocarditis developed in the mitral and in 1 in the aortic valve. Of 3 patients with preexisting heart disease, 2 had involvement of the aortic valve and 1 of the mitral valve. Six patients were cured, 2 or possible 3 by treatment with ampicillin, 2 with cephalothin, and 1 with co-trimoxazole. In 2 patients intractable heart failure necessitated the insertion of prosthetic valves, and 1 patient died. Thus, cases of septicemia and endocarditis due to H. parainfluenzae have been observed only in recent years and they appear to be serious infections.

Gram-negative endocarditis was uncommon in the past, accounting for 1% to 3% of cases. With the advent of antibiotics, immunosuppressive agents and narcotic abuse, the number has increased to 5% to 10% in the native valves and as high as 17% in the prosthetic valves, with Haemophilus species as the commonest aetiological agent, accounting for about 1% of the cases. We report a case of Haemophilus parainfluenzae endocarditis in a 39-year-old man who presented with heart failure and persistent fever. Echocardiography showed bi-leaflet mitral valve prolapse and severe mitral regurgitation. A small vegetation was seen at the flail anterior valve leaflet. He responded well to 4 weeks of intravenous ampicillin at 9 g/day and 2 weeks of gentamicin at 4 mg/kg/day, and subsequently underwent valve replacement.

Haemophilus parainfluenzae, a human commensal, is an infrequent cause of serious disease. A case of endocarditis caused by this organism in a five year old boy with complex congenital heart disease is reported. The course of this disease was very aggressive, leading to heart failure, disseminated intravascular coagulation and multiorgan failure in spite of appropriate antibiotics and surgical intervention. The difficulties in the detection and identification of H parainfluenzae using conventional culture based technology, and the potential role of molecular techniques, are highlighted.
