Yellow staining of central nervous system (CNS) nuclei occurs in the brains of some neonates, despite low levels of serum bilirubin. Two conditions appear to be important in the evolution of this form of kernicterus: prematurity and asphyxia. In a seven year retrospective study of a large neonatal autopsy population, 102 cases had kernicterus as indicated by selective macroscopic yellow staining and microscopic damage within specific CNS nuclei. Neuropathological study disclosed minor variations and numerous similarities in the manifestations of kernicterus in the asphyctic premature neonate with low levels of serum bilirubin, as compared to kernicterus in the full-term neonate with high levels of serum bilirubin. Acidosis, hypoxia, hyperoxia, hypothermia and sepsis have been considered significant risk factors, but recent comparative clinical studies have not defined predictive indices. Analysis of this disorder is difficult because of the concurrence of other complications of asphyxia and its pathological correlates in premature infants. Diagnostic difficulties are also compounded by variations in the definitions of kernicterus as used by different investigators.

Two hundren sixty-seven neonates who received parenteral nutrition were monitored for signs of liver dysfunction. Cholestatic jaundice occurred in we infants, with a higher incidence in the more immature infants. There was an inverse correlation between severity of jaundice and the degree of prematurity. Infants with cholestasis remained without gastrointestinal feedings and received parenteral nutrition for periods of time significantly higher than infants without cholestasis. The incidence of this complication did not seem to correlate with the amount of protein infusate (amino acid solution). A higher incidence of sepsis was noted in infants who were affected by cholestasis. Close monitoring for signs of liver dysfunction in all neonates receiving parenteral nutrition is strongly recommended.

The risks to the infant following prolonged premature rupture of the amniotic membranes are those of prematurity and infection. After the 36th week of pregnancy, healthy infants of healthy mothers may be treated as uninfected neonates, as their risk of infection does not appear to be significant. Before this gestational age, infants should receive a complete laboratory evaluation for infection, including blood culture and spinal fluid examination, and antibiotic therapy should not be withheld until these laboratory tests are reported to the clinician. While the indiscriminate use of antibiotic treatment should be avoided, sepsis in the newborn can be a rapidly progressive disease, with minimal physical and laboratory findings at its onset. Therefore, until some method of laboratory evaluation that will detect all cases of neonatal sepsis rapidly, and leave no infected infant unidentified, the clinician must be alerted to the presence of an infant delivered after PROM and institute the appropriate evaluation and treatment as soon as possible.

In the past 40 years, the predominant organisms responsible for neonatal sepsis have changed. Whereas Group A betahemolytic streptococci were originally most common and staphylococci later became the major pathogens, Group B beta-hemolytic streptococci have become increasingly important in recent years. Predisposing factors include premature rupture of membranes, prolonged difficult labor, prematurity and congenital anomalies. The causes and clinical features of early-onset infection (in the first week of life) and late-onset infection are different.

A retrospective analysis of infants with necrotizing enterocolitis was done to evaluate the effects of preoperative abnormalities upon anaesthesia and mortality. Mortality was significantly increased in infants weighing less than 1500 grams (p less than .001). Sixty-nine per cent of the infants had hyaline membrane disease and 35 per cent had platelet counts less than 50 X 10(9) cells/litre (50,000/mm3). Perioperative problems include peritonitis, sepsis, hypovolaemia, acidosis, and prematurity. Other ramifications of prematurity and anaesthesia are discussed.

Candida albicans arthritis in the pediatric patient is rarely reported. In each instance, the patient has had one of the factors that predispose to fungal sepsis: broad spectrum antibiotic therapy, hyperalimentation, prematurity, abdominal surgery, corticosteroid or immunosuppressive therapy, malnutrition, maternal vaginal candidiasis, or lymphoproliferative disorders. To avoid the potentially fatal consequences of delayed treatment, early recognition of the disease is imperative. The patient usually refuses to use the affected joint and plain radiography shows a joint effusion with soft tissue swelling. Osteomyelitis develops in approximately half of the cases. Arthrocentesis with fungal cultures is the best method to make the diagnosis. Treatment is primarily chemotherapeutic and the drug of choice is the membrane inhibitor amphotericin B given intravenously. The antimetabolite 5-fluorocytosine is a second-line drug to be used if resistance develops. All cases before the present one involved the knee joint initially. The case presented involved the left hip and was successfully treated with intravenous amphotericin B.

Eight cases of materno-fetal listeriosis were discovered at the University Women's Hospital of Basel from May 1977 until June 1980. This represent an incidence of 0,15% of all births. This infectious disease has often a fatal course for the unborn child, therefore it is important to know the clinical manifestations occurring with it. Listeriosis during pregnancy has a typical-two-stage course: During the first phase we see commonly a flu-like illness abating rapidly, about two weeks later fever starts again and premature contractions ensue, but no therapy is successful in controlling the fever and the premature labour. The usual fate for the unborn child is stillbirth or premature delivery with subsequent neonatal death due to prematurity, RDS, sepsis and meningitis. The low fetal and neonatal survival rate can be improved by two relatively simple measures: 1) a high index of suspicion with early diagnosis, 2) an early treatment with ampicillin either in the antepartal or neonatal stage. We review the epidemiology, the bacteriology, the serology and the histo-pathology of this relatively rare but important disease during pregnancy.

Fungal infections of the heart are infrequent postoperative complications in children, yet, when present are often fatal. Children autopsied at The Johns Hopkins Hospital from 1889 to the present were studied for cardiac fungal infection. Among the 14 children so identified, 8 developed cardiac fungal infection after surgery. All postoperative cardiac infections were caused by Candida species. All were autopsied since 1959. Gastrointestinal surgery was performed in 6 patients and cardiac surgery in 2. Candida infection was not confined to the endocardium; endocarditis developed in 2 patients, pericarditis in 1, and myocarditis in 5. None received cytotoxic agents or corticosteroids. Two patients died from direct cardiac involvement. Other deaths were related to Candida sepsis or bronchopneumonia. A clinical diagnosis of cardiac fungal infection was never made. Prolonged administration of multiple antibiotics, central venous catheterization, prematurity and immune deficiency predisposed to cardiac and systemic candidiasis. Clinical features facilitating early diagnosis are discussed. Removal of central venous catheters infected with Candida did not eliminate the source of continued sepsis, since Candida-laden vegetations related to the catheter adhered to the superior vena cava and endocardial surface. Postoperative cardiac candidiasis is a relatively new and persistent problem of early diagnosis and therapy. The post-surgical pediatric patient has major predisposing factors for cardiac candidiasis, which, if unrecognized, may be a source for continued dissemination or may in itself be the cause of death.

One-hundred twenty-nine high-risk infants with thrombocytopenia and 238 control infants without thrombocytopenia were evaluated. Mothers of thrombocytopenic babies had similar history to those of nonthrombocytopenic babies, although fewer chronic narcotic abusers were found among mothers of thrombocytopenic babies. Thrombocytopenia was more common in babies less than 37 weeks' gestation and in sick babies compared to healthy babies. Sixty percent of infants had no recognizable cause of thrombocytopenia. Features associated with thrombocytopenia included umbilical line placement, respiratory assistance, hyperbilirubinemia, phototherapy, prematurity, respiratory distress syndrome, low Apgar score, sepsis, meconium aspiration, and necrotizing entercolitis. Thrombocytopenic babies had Apgar score, sepsis, meconium aspiration, and necrotizing entercolitis. Thrombocytopenic babies had more complications, more hemorrhage, and greater mortality than nonthrombocytopenic babies. Platelet size was increased in two babies with immune thrombocytopenia and in none of the others. This study shows that neonatal thrombocytopenia is often associated with high-risk factors and with increased hemorrhage, morbidity, and mortality. This relationship suggests an important prognostic value to platelet size was increased in two babies with immune thrombocytopenia and in none of the others. This study shows that neonatal thrombocytopenia is often associated with high-risk factors and with increased hemorrhage, morbidity, and mortality. This relationship suggests an important prognostic value to platelet counts, although the extent to which the thrombocytopenia contributed directly to morbidity and mortality is not clear.

The leukocyte glycoprotein L-selectin mediates an early step in the recruitment of leukocytes to sites of inflammation. L-Selectin surface expression is rapidly down-regulated by inflammatory signals in vitro. In a prospective study, we found L-selectin expression on umbilical cord blood granulocytes and monocytes to be significantly decreased in newborn infants with acute bacterial infection compared with controls (p < 0.01). A significantly reduced L-selectin expression of both granulocytes and monocytes was also found to be associated with an increased neutrophil immature/total ratio (p < 0.01) but not with other laboratory markers of neonatal sepsis. There was no apparent impact of prematurity, low birth weight, gestational hypertension, or gestational diabetes on L-selectin expression. Although the mode of delivery did not affect granulocyte L-selectin expression, umbilical cord blood monocytes showed an increased L-selectin expression after emergency cesarean delivery compared with samples obtained after elective cesarean or vaginal delivery (p < 0.01). We conclude that acute systemic inflammation results in down-regulation of granulocyte and monocyte L-selectin expression in vivo similar to that observed in vitro.
