For a period of 17 months, 670 pneumococci, mostly isolated in the Paris area, have been typed with contercurrent-immunoelectrophoresis ; 338 of them come from cases of pneumonia, bacteremia, meningitis and acute otitis media. An important regrouping of the most frequent serotypes among the 83 known serotypes makes possible a vaccinal prophylaxis. The tetradecavalent vaccine which is now for sale in USA gives, in the four main pathologies of this enquiry, a coverage superior to 80 percent. Choosing the 14 most frequent serotypes of the four main pathologies of their data the authors propose the following vaccinal formula : 1, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 18, 19, 23.

In spite of extreme and persistent susceptibility to antibiotics, specially benzylpenicillin, the pathology due to pneumococcus remains frequent and serious. From 14 cases of pneumococcal meningitis associated with pneumonia the authors have studied the relationship between these two localizations. They conclude that meningeal seeding appears most frequently secondarily and is probably latent at the beginning. Moreover they note that treatment of pneumonia by itself does not always prevent the occurence of the meningitis. Density of bacterial population, prolunged bacteremia, resistance of pneumococcus to phagocytic mechanisms and the delay of treatment might explain these findings. For those reasons the authors recommend the use of high doses of benzylpenicillin for the treatment of lately diagnosed bacterial pneumonia.

The records of 207 patients with pneumococcal meningitis admitted to Ahmadu Bello University Hospital, Zaira, northern Nigeria, between February, 1971 and June, 1976 have been reviewed. Mortality was 51%. Death was more likely in patients with a short history, impaired consciousness on admission, and an associated pneumonia. Cerebrospinal fluid levels of protein, lactate, fibrin degradation products, and polysaccharide antigen were higher in patients who died than in survivors.

A new alpha-sympathicomimetic drug with peroral effect is midodrine. The effective oral dosage in infancy and childhood is 0.06 mg/kg/dosi. The therapeutic effect, comparing the drug with etilefrin is shown in 120 children with pneumonia, enteritis, meningitis in a random study. The results give an increase in blood pressure and a decrease in heart frequency, statistically proved, on the first day of treatment. Therefore it seems that midodrine is qualified for the treatment of hypotension in infectious diseases.

Antibiotics and chemotherapeutics have been available for about 40 years, but still bacterial infections constitute some of the greatest problems in medicine. Pneumococci causing pneumonia, bacteremia, meningitis and otitis are a leading cause of illness and death. The exact incidence and lethality of pneumococcal infections is not known, however, since they are not reportable diseases in most countries and since microbiological diagnosis is difficult. In the latest years some significant progresses have been made for the diagnosis of infections caused by pneumococci, especially pneumonia. This is for example the counterimmunoelectrophoresis (CIE) for antigen determination, the transtracheal aspiration (TTA) for direct bacterial cultivation from trachea, and serological assays like radioimmunoassay (RIA) and enzyme-linked immunosorbent assay (ELISA) for pneumococcal capsular antibody determination. These techniques have further emphasized the significance of pneumococcal infections. The recent finding of pneumococci resistant to penicillin and some other antibiotics also emphasizes the need for immunological prophylaxis. In recent years a vaccine consisting of the purified, most common pneumococcal polysaccharides has been introduced. It has been shown to protect against pneumonia, pneumococcal infections in splenectomized individuals and people with spherocytosis and probably partly against otitis media. Indications for the vaccine are suggested.

Group B streptococci (GBS) are responsible for serious infections of newborn infants. An experimental model for GBS infection was developed in the newborn rhesus monkey in order to obtain more information concerning the pathogenesis of such infections. A series of 29 newborn monkeys were inoculated with either type Ic or type III GBS or sterile broth. Fatal neonatal meningitis without associated pneumonia was produced consistently following intracerebral inoculation with either type Ic or type III; intracerebral inoculation with sterile broth produced no apparent disease. Variable disease production followed intravenous or intra-amniotic GBS inoculation, and clinical manifestations ranged from no apparent disease to fatal meningitis and pneumonia. This monkey model may be useful for further investigation of treatment and prevention of neonatal GBS infection.

The course of disease of a patient with membranoproliferative glomerulonephritis and partial lipodystrophy is described. The case is further characterized by a deficiency of C3 and C3- activator, by normal values of C4, by evidence of the nephritogenic factor, by raised fibrin degradation products and by an unselective proteinuria. The course of the glomerulonephritis runs parallel to a pronounced susceptibility to infection (at first varicella, tonsillitis and measles, later pneumonia, meningitis, encephalitis and hepatitis). On account of a nephrotic syndrome and an initative impairment of the renal function, a cytostatic treatment was begun, which although raising the C3 level did not influence the further course of the disease. As the patient has a healthy identical twin sister without lipodystrophy, who shows no reduction in C3 and no nephritogenic factor, this case proves that these diseases are acquired and not genetically determined.

A case of pneumococcal endocarditis in an infant is reported together with a review of seven cases previously described in the literature. The prominent presenting symptoms of this usually fatal disease consisted of tachycardia, tachypnea, and cardiomegaly. A new murmur was heard in six of the eight patients. Fever was infrequent. Blood cultures were positive when done. The mitral valve was the site of infection in seven of the patients. In contrast to adult patients, pneumonia and meningitis are rarely encountered in children with pneumococcal endocarditis. The disease was fatal in all four patients before the penicillin era and in three of four patients who received penicillin.

During bacterial infections, the intensity of the polymorphonuclear leukocytosis depends on the bacterium but also on the mechanism and extent of the infection. Polymorphonuclear leukocytosis is greater during pyogenic and anaerobic infections. It is due to deep suppuration, septicemia of thrombophlebitic origin, acute endocarditis, purulent meningitis and pneumonia. The increase in the number of polymorphonuclear cells is, on the other hand, less marked in sub-acute bacterial endocarditis. Apart from bacterial infections, a polymorphonuclear leukocytosis is common in inflammatory disease, such as tissue necrosis and several malignant diseases. It may also be due to drug allergy.

Serogroup Y meningococci are more frequently respiratory pathogens than one might suppose from their prevalence in meningitis and septicemia. A case of a peracute fatal septicemia caused by group Y meningococci is reported here in which post mortem hemorrhagic lesions of the pharyngeal, laryngeal and tracheal mucosae as well as a beginning pneumonia and pleurisy have been found. The association of meningococcal and respiratory viral infections is discussed.
