Five infants with pneumococcal sepsis presented with respiratory distress and clinical signs of infection in the first day of life. Although there was no apparent epidemiological relationship among the patients, four of the five were seen within a 12-month period. Pneumonia, prolonged rupture of fetal membranes, and prematurity were features in these patients. Three infants died, two within 12 hours of diagnosis. Streptococcus pneumoniae was isolated from the vagina of three of the mothers; in two, the serotype was identical to that recovered from their infants. Clinical features of neonatal pneumococcal sepsis are similar to those of early-onset group B streptococcal infection. Like the group B Streptococcus, S. pneumoniae acquired from the maternal vagina is a potential life-threatening pathogen in the newborn period.

Sequenital mechanical pulsing of the chest wall with three stimuli failed to induce arrhythmias in normal dogs. After coronary arterial occlusion, this technique evoked in 11 of 12 animals repetitive ventricular tachycardia in 2. These responses corresponded closely to those elicited by electrical testing. In four conscious animals after recovery from myocardial infarction, precordial pulsing induced repetitive ventricular arrhythmias. The type of arrhythmia produced depended on the degree of prematurity of the third pulse in the sequence. The use of precordial mechanical stimulation can perhaps be modified and adapted as a method of detecting persons at high risk for sudden cardiac death.

In a comparative study of the course of pregnancy and delivery of 357 patients who delivered live infants between 1966-1976 following cerclage operation were compared to a control group of 380 without cerclage who were matched in age, parity and delivery time to the group under study. The high prematurity rate in the pregnancies preceeding the cerclage of 28.4% decreased following the cerclage to 16.8% (p less than 0.001). The perinatal mortality was reduced from 21.5% to 5.6% (p less than 0.001). This effect was especially achieved by the lower incidence of deliveries of infants with a birth weight of less than 1500 grams (p less than 0.05). The difference to the controls regarding prematurity (8.2%) and perinatal mortality (1.6%) remained significant (p less than 0.001). An increased rate of malformations in the cerclage children was not noticed. The maternal risk is low and consists mainly of a increase of cervical lacerations (4.9%) and problems of wound healing (2.2%). The duration of labor and type of delivery, the type of third stage of labor, and the post-partum course were not different from the control group.

Prematurity has traditionally been connected with thrombocytopenia, although this is unlikely to be associated with prematurity itself but rather with serious illnesses in such infants. Platelet counts were measured in 117 healthy preterm infants with birthweights less than 2000 g, who were followed up from 2 weeks to 6 months. In this series the platelet counts were high compared with those in previous reports, and also compared with what is considered normal for term infants. The 95% range was between 160 and 675 X 10(9)/1, with a median value of 375 X 10(9)/1. The data suggest that thrombocytosis is a phenomenon related to prematurity.

The effect of middle-ear dysfunction and disease on hearing and language development at one year of age was evaluated for 143 high-risk infants. These infants were categorized as normal or abnormal based on otologic history, otoscopic examinations, and on tympanometric examinations. Language was significantly related to gestational age, being delayed by approximately the amount of prematurity. Language scores were therefore adjusted for gestational age. Speech-detection threshold was not related to gestational age, and was used as the measure of hearing. Hearing levels were negatively correlated with adjusted language quotients. Infants with abnormal otologic histories reported were not different from infants with normal histories in either hearing or language development. Infants with bilateral otoscopic abnormalities had significantly higher speech-detection thresholds, but did not differ in language development from those with bilaterally normal otoscopy. Infants who were abnormal bilaterally by tympanometric examination had significantly higher speech-detection thresholds as well as significantly delayed language development. A significant effect on both hearing and language was found among those infants bilaterally abnormal by tympanometry for whom evidence of middle-ear disease was not visualized by otoscopic examination. Implications of these findings are discussed.

805 narrative summaries from pregnancy, delivery and neonatal period were examined to find out factors which might influence physiological jaundice in the newborn period. The normal range of bilirubin is: 70% of all newborn babies have maximum bilirubin levels below 10 mg/100 ml, while 2.6 exceed 16 mg/100 ml as maximum. Under special conditions i. e. prematurity, small for date babies, male sex, very young and very old mother bilirubin is higher that normal. EPH-gestosis, high birth weight, stress during delivery, very small and very big placenta are followed by diminished bilirubin levels. These findings are discussed in detail.

Eight infants who developed HBsAg aged between 1 and 5 months were identified in the greater Copenhagen area during the period 1970--76. 7 had acquired the infection from their mothers and one had received a HBsAg-positive blood infusion, 3 infants had a transient infection lasting 2 to 8 months while the remaining cases developed persistent antigenaemia with evidence of minor liver dysfunction during a follow-up of one to 6 years. HBeAg was persistently present in 4 of 5 infants, indicating infectivity in these patients. Prematurity or administration of specific immunoglobulin at delivery apparently did not affect the course of infection.

Involuntary infertility is a public health problem for couples in Africa where a suspected belt of low infertility stretches across Gabon, Cameroon, Peoples Republic of Congo, Central African Empire, Zaire, Uganda and Southern Sudan. No single factor has been isolated as the cause, however, secondary infertility is highly correlated with induced or spontaneous abortion. 388 patients were seen over a 2 year period in Cameroon. 149 were primary and 238 were secondary cases of infertility. Ages of patients ranged from 16-40 years. The majority of secondary cases had delivered their babies in private or public health facilities. It was hypothesized that an infection was contracted in the hospital. Puerperal infection was studied at the Central Maternity in Younde. Neisseria gonorrhoea was found to be 25% incidence, high enough to be considered an epidemic. Improved facilities for diagnosis and neonatology, particularly the prevention of prematurity, are needed. Women in Cameroon are more afraid of infertility than of cancer.

We compiled the results of pars plana vitrectomy in rare proliferative and hemorrhagic diseases. In retinal vasculitis of unknown origin (perhaps Eales' disease), six out of seven eyes had visual improvement; in sickle cell disease, two out of three eyes improved. Three eyes with presumed toxocariasis were successfully treated. In retrolental fibroplasia (RLF), only lighter degrees of the cicatricial stage with traction detachments can be treated. Some cases may simulate Coats' disease. There are also cases which simulate the typical picture of RLF, where there is no history of prematurity or oxygen usage. Five patients with RLF were treated, three of these successfully. Cryoglobulinemia (one case) and hereditary hemorrhagic telangiectasia (one case) were successfully treated. Senile macular degeneration can also be an indication for vitrectomy (two out of three eyes were successfully treated).

To determine the differences between pregnancies complicated by placenta previa and those without placenta previa, the characteristics of 31,070 consecutive deliveries at one institution were analyzed. The philosophy of "expectant management" of the premature fetus and frequent use of cesarean section was utilized in the 185 patients with placenta previa. A higher proportion of these patients were multiparous, were older, had had previous abortions, and were carrying a male fetus or twins. The fetal and placental weights in these patients were similar to those in other patients throughout pregnancy. Rates of prematurity, antepartum and intrapartum fetal death, neonatal death, congenital abnormality, and low Apgar scores were higher among patients with placenta previa. Data were compiled in a manner that allows the obstetrician to: (1) evaluate the fetal weight and expected fetal growth; (2) estimate the probability that his patient will deliver prematurely and will deliver within the next one-, two-, or four-week interval; (3) determine the relative risks to the fetus prior to labor, during labor, and in the neonatal period at each stage of gestation.
