Diseases which manifest with the respiratory distress in the newborn include 1) respiratory diseases-IRDS, type II RDS, neonatal asphyxia, and MAS etc. 2) anemia, CHD 3) CNS and 4) metabolic diseases. Among these, IRDS has high mortality rate because of the lack of the pulmonary surfactant and immaturity of respiratory center, and has many difficult problems in terms of its prevention and respiratory management. The points of its respiratory management are as follows: 1) Estimation of the level of arterial oxygen ation-this is the most important point. It has become possible, these days, to monitor continuous oxygenation using a transcutaneous oxygen electrode. 2) Knowledge of the physiology & management of apnea, and monitoring of heart rate and respiration. 3) Correction of acidosis & anemia and the nutritional supply by the intraveonous fluid administration. 4) Airway maintenance. 5) Oxygen administration to main PaO2 or tc PO2 of 60--80 mmHg. 6) Artificial ventilation by CPAP or IMV and 7) The specific drug therapy includes indomethacin for PDA associated with IRDS, Tolazoline for the fetal circulation syndrome, and Xanthine derivatives for primary apnea. 8) However, improvement by exchange transfusion has been contro-versial. On the other hand, in the type II RDS which has a relatively good prognosis, the intact survival can be expected by means of the proper management of general condition and respiration. In MAS, pneumothorax, pneumomediastinum and severe asphyxia, the proper resuscitation, oxygen administration should be given according to several conditions, especially the degree of hypoxia. The peritoneal dialysis can be lifesaving in case of severe renal impairment with RD. As the respiratory distress in the newborn is very frequent in its occurrence and death rate, its proper management is expected to result in the decrease in the newborn death rate in Hokkaido (8.1--6.6 per 1,000 live births) and the increase in the survival rate without any handicap, particularly if hospitals in each Hokkaido district give the newborn medical care more intensively than at present.

The clinicopathological associations of 33 singleton infants who died with intraventricular haemorrhage (IVH) without hyaline membrane disease (HMD) ('IVH only') were compared with those of 39 infants who died with IVH+HMD over the same gestation range in order to determine what factors other than those related to HMD may contribute to the pathogenesis of IVH. The incidence of 'IVH only' was inversely related to gestational age in the Hammersmith birth population, whereas the incidence of IVH+HMD rose to a peak at 28-29 weeks' gestation. Infants with 'IVH only' lived longer on average than those with IVH+HMD despite a lower birthweight and shorter gestation. Infants who died in the first 12 hours from 'IVH only' had suffered severe birth asphyxia but in those who died later the main symptom was recurrent apnoea. Fewer infants with asphyxia but in those who died later the main symptom was.recurrent apnoea. Fewer infants with 'IVH only' were given alkali therapy or were connected to the ventilator as compared to those with IVH+HMD, but there were no differences in alkali therapy in those who lived for 12 hours or more. In the 'IVH only' group there was a high incidence of haemorrhage from other sites and of bacterial infections. It is suggested that, in the absence of HMD, extreme immaturity is the main factor determining the occurrence of IVH. Birth asphyxia, apnoeic attacks, haemorrhage, and infections may play subsidiary roles, possibly through development of metabolic acidosis.

Infants of very low birth weights (less than 1500 g) born before the 32nd week of gestation have a high incidence of neonatal intracranial hemorrhage (ICH). Beside perinatal and postnatal asphyxia the main risk factor for ICH is the immaturity of the infant. Mild intracranial hemorrhages resolve within a few weeks. Severe ICH, which were seen in very immature babies before 30 weeks of gestation and with birth-weights below 1250 g had a fatal outcome. The mortality rate in severe ICH was 50%. The infants which survived severe ICH developed posthemorrhagic hydrocephalus (PHH). Using the open fontanelle as an acoustic window gray scale ultrasonography of children's brain is able to visualize ICH and PHH. We suggest early sonografic brain investigation within the first days of life in all prematurely born infants with perinatal asphyxia. Infants with severe ICH should have weekly sonografic controls, to detect PHH as soon as possible.

In five cases of congenital pulmonary lymphangiectasis, light microscopic features of the lungs and measurements of their lymph vessel lumina are presented. All lung sections show the same histologic characteristics: a network of partly tubular, partly cystically enlarged lymph vessels within large areas of connective tissue. The lung sections in four cases with pulmonary vein outflow obstruction, the so-called secondary form according to NOONAN et al. [28], do not differ from those in primary lymphangiectasis without obstruction in the pulmonary vein outflow area. The author's own observations are discussed together with 57 cases from the literature. Among the 26 cases of secondary lymphangiectasis are 15 children with aberrant pulmonary veins, and 11 children with hypoplasia of the left side of the heart. Clinically, both forms present with neonatal asphyxia and massive respiratory distress, usually with a fatal outcome within the first few days of life. Hyaline membrane disease may be accompanied by pulmonary lymphangiectasis to a degree that renders its distinction from congenital lymphangiectasis difficult. The lungs in 5 cases with hyaline membrane disease are compared to those in 5 cases of congenital lymphangiectasis. In the former, distended lymphatics are primarily interlobular in location, while in congenital lymphangiectasis they are also found in the subpleural and periarterial tissues. In addition, they are widened to a lesser degree than in the congenital form. In the latter the lymphatic vessel walls are markedly thickened, and the pulmonary lesions, particularly the signs of immaturity, typical for hyaline membrane disease, are lacking.

Singleton survivors born to multigravidae in the whole island of Jamaica in 2 months (September-October 1986) were compared with singleton perinatal deaths occurring to multigravidae throughout the island in the 12-month period September 1986 to August 1987. Past obstetric history was obtained from the mothers using a structured questionnaire. Deaths were categorised using the Wigglesworth classification. Logistic regression was used to compare current outcomes in women who had had at least one previous pregnancy. Antepartum fetal deaths with (1) outcome of last pregnancy; (2) previous Caesarean section; (3) previous stillbirth; and (4) increasing gravidity. In the presence of these factors maternal age ceased to be statistically significant. Deaths from immaturity were strongly associated with the past obstetric history, with increased risks for pregnancies to mothers with a history of previous miscarriage, perinatal death and premature live births. In general, however, the higher the gravidity the lower the risk. In the presence of these factors, maternal age showed no significant association. Intrapartum asphyxia was also associated with the outcome of the last pregnancy, history of prior stillbirth or neonatal death. First pregnancies were at significantly higher risk than second pregnancies (P < 0.05). For perinatal deaths as a whole, and in the presence of maternal age, the following were statistically significant independent factors: (1) the outcome of the immediately preceding pregnancy (high risks associated with prior miscarriage, stillbirth and premature live births); (2) previous Caesarean section (increased risk); (3) previous perinatal deaths; and (4) more than one prior early fetal loss. The results indicated that prior poor obstetric history bears similar risks of subsequent adverse outcome in the developing as in the developed world. There was no variation in risk, however, with interpregnancy interval or previous termination. Much of the variation in risk of perinatal death with maternal age among multigravidae appears largely to be secondary to past obstetric history.

This paper reports the creation of India's national neonatal-perinatal database. The database has a continuous reporting format, uniform in its definitions, and is checked and compiled at a nodal center, which is a necessity for planning and monitoring health care. Data were compiled from intramural births of 16 centers, which included neonatal morbidity and mortality data for the year 1995. Furthermore, the database comprised data on 38,592 births, 37,082 of which were live-born and 1510 stillborn. Statistics show that the incidence of low birth weight (LBW) was 32.8% and that of preterms 12.3%, while two-thirds of the LBW infants were term babies. Among institutional births, the incidence of birth asphyxia would approximate 5%, while septicemia was observed in 3.9% of intramural live births. Birth asphyxia, septicemia, and causes related to immaturity account for almost three-fourths of the neonatal deaths, a majority of which could be prevented.
