Coagulation and fibrinolysis studies were performed on 64 newborns; 16 premature infants with hyaline membrane disease (HMD), 17 newborns with other forms of respiratory distress syndrome (RDS) (8 of them were premature), 31 healthy newborns (11 of them were premature). All the babies were studied once in the first 48 hours of life. There was no significant difference between sick and healthy babies for 5 parameters; platelet count, factor VIII, fibrinogen, fibrin(ogen) degradation products, euglobulin lysis time. Factor II, VII and X were low in all infants, and premature infants had significantly lower levels compared to full term newborns. Factor V, plasminogen, alpha 2 macroglobulin (alpha 2M) and antithrombin III (AT III) levels were significantly lower in sick infants. Except for AT III, these deficiencies were not related to prematurity. No significant difference was found between HMD and other RDS. Of the 33 sick infants, 5 developed laboratory findings consistent with disseminated intravascular coagulation (DIC). The results indicate that the coagulation and fibrinolytic abnormalities reported are not specific to HMD.

Pneumonia is one of the most serious infections in the neonate and is responsible for a large percentage of neonatal mortality. Pneumonia in a premature or term infant who is debilitated by an underlying problem such as hyaline membrane disease carries an extremely high morbidity and mortality. Since most of the bacterial pneumonias are treatable, early recognition and diagnosis and vigorous treatment are essential. X-ray findings, though helpful, serve only as a guideline. Prognosis is adversely affected if pneumonia results in generalized sepsis, leading to meningitis, disseminated intravascular coagulation, and osteomyelitis. Prompt antibiotic treatment should be begun before the etiologic agent or drug susceptibility is known.

Neonatal nonbacterial thrombotic endocarditis (NBTE), a rare disorder yet to be diagnosed antemortem, is described in two infants. The first infant was postmature and suffered from polycythemia and meconium aspiration. The meconium-stained placenta manifested evidence of ischemia and disseminated intravascular coagulation (DIC). The second patient was delivered near term by cesarean section, and hyaline membrane disease developed. The pathogenesis of NBTE may relate to perinatal hypoxia with transient tricuspid insufficiency, polycythemia, and DIC.

We have reviewed 53 cases of disseminated intravascular coagulation (DIC) in the newborn, including 29 cases that were confirmed at autopsy. Factors predisposing to DIC included maternal complications (60%), low Apgar scores (30%), hyaline membrane disease (62%), and sepsis (26%). Diagnostic criteria common to autopsy-proved cases included presence of fibrin degradation products, low factor V activity, a prolonged prothrombin time, and a prolonged partial thromboplastin time and/or thrombocytopenia. There appeared to be no difference in coagulation response or in mortality among patients treated with different therapeutic regimens. Survivors were older gestationally, had higher birth weights, and higher Apgar scores.

A total of 209 consecutive neonate and infant autopsies were reviewed with special attention to papillary muscle necrosis (PMN) of the heart. Associated major pathological findings were analysed for the evaluation of significant pathological accompaniments of PMN. PMN was found in 52 cases among 171(30.4%) neonates and major pathological accompaniments were bronchopneumonia, hyaline membrane disease, hypoxic neuronal change, sepsis, subarachnoid hemorrhage, disseminated intravascular coagulation (DIC) and acute tubular necrosis, among which hypoxic neuronal change and ATN had a statistically significant higher incidence when compared with the control group. (p < 0.005). PMN was found in 13 cases among 38(34.2%) infants and accompaniments were congenital heart disease, sepsis, bronchopneumonia, DIC and hypoxic neuronal change, all of which showed no difference from the control group in incidence. The results imply that PMN is a kind of organ damage in stressed subjects regardless of age, that it is not a special form of myocardial injury in any specific age group including the newborn period, and is possibly of different pathogenesis and significance.

Disseminated intravascular coagulation (DIC) and other clotting abnormalities are common in sick newborn infants who have a variety of conditions. To document evidence of DIC at autopsy, immunoperoxidase staining of fibrin-related antigens (FRA) was used to detect intravascular microthrombi in liver, kidney, and lung from 127 newborns. Patients were selected from seven major disease groups: hyaline membrane disease/bronchopulmonary dysplasia, infection, meconium aspiration, necrotizing enterocolitis, congenital heart disease, other congenital anomalies, and extreme prematurity. Staining for FRA in intravascular microthrombi was seen in 40% of cases studied. The liver showed the highest frequency of intravascular microthrombi, located predominantly in the sinusoids. Unlike the adult kidney, the newborn kidney seldom had evidence of intravascular coagulation. Extravascular staining of FRA was observed in the renal distal tubular epithelium in 48 cases, many of which also had evidence of intravascular FRA staining. No significant differences in FRA staining patterns were seen among the disease groups except for cases of extreme prematurity in which all tissues showed minimal staining. Control tissues from SIDS patients also showed minimal FRA staining. Hepatic sinusoidal staining was the only tissue finding that correlated with thrombocytopenia, a clinical indicator of DIC. Despite the use of this immunohistochemical staining method, discrepancies between the clinical and autopsy diagnosis of DIC remain.

We have reported a case of malignant lymphoma in associated with Hashimoto's disease arising in the right lobe of thyroid of a 57-year-old woman. The pre-operative aspirated biopsy was valuable for diagnosis Immuno-histochemical observations revealed the localization of anti B cell antibody in the cell surface of lymphoma cells and anti thyroglobulin antibody in intactly follicular epithelium within the lymphoma tissue. This lymphoma was diagnosed as diffuse, medium cell and B cell type. Radiation and chemotherapy were performed for multiple metastasis of liver and brain, but this case had died of DIC and diffuse hyaline membrane disease of lung.

Two hundred and one consecutive autopsies of the newborns were clinicopathologically analyzed for the prevalence of disseminated intravascular coagulation (DIC) and its significance as a cause of death. DIC confirmed histopathologically by the presence of many microthrombi in three or more organs was accompanied in 24 cases (11.9%) with various underlying diseases. Factors predisposing to DIC in the newborns included hyaline membrane disease (29.2%), maternal complications (70.8%) and infections (16.7%). Microthrombi were found in the lungs of all the cases with DIC, but were rare in the kidneys, especially in glomeruli. Visceral lesions of DIC were characterized by a wide diversity of histopathological features including ischemic lesions.

During the 19-month study period, 48 (2 per cent) of the 2177 neonates admitted to the neonatal intensive care unit (NICU) yielded Pseudomonas aeruginosa growths in blood cultures. All these neonates had clinical and haematological evidences of sepsis. Prominent clinical features included sclerema, violaceus necrotic patches, necrotizing enterocolitis (NEC), conjugated hyperbilirubinaemia, and DIC. Over all mortality was 23 per cent, distinctly higher in premature neonates with RDS. The mean gestational age and birth weights (+/- SD) of these neonates were 36.42 (+/- 2.73) weeks and 2173.34 (+/- 567.33) g, respectively. Approximately half of the total cases had low birth weight. Other adverse perinatal events before the development of sepsis included birth asphyxia (60 per cent), neonatal resuscitation (67 per cent), meconium aspiration syndrome (29 per cent), hyaline membrane disease (8 per cent), prolonged hospitalization (44 per cent), closed incubator care (17 per cent), prolonged intravenous fluids (42 per cent), repeated blood sampling (63 per cent), and umbilical catheterization (4 per cent). Analysis of the trend of Pseudomonas sepsis in our NICU revealed six definite outbreaks (more than two cases) interspersed with occasional (one or two) cases. Six study months, however, remained free of Pseudomonas sepsis. Index case was demonstrable on seven occasions. Bacteriological surveillance of the NICU after onset of initial case/cases revealed statistically significant colonization of resuscitation equipment, baby placement sites, and various cleansing solutions by the same bacterial species (P < 0.05). It is possible that Pseudomonas was introduced to our NICU from transfer admissions from other hospitals since on four occasions index case was the one transferred from outside.(ABSTRACT TRUNCATED AT 250 WORDS)

Pathomorphology in the preterm infant represents an interaction of morphological organ immaturity and neonatal management with their respective sequelae. PATHOMORPHOLOGICAL EXAMPLES: include the modification in the morphology of hyaline membrane disease and bronchopulmonary dysplasia as a consequence of modern neonatal therapy. Hemorrhagic and ischemic/ hypoxic lesions of the central nervous system may occur in age- and agent-related distributional patterns, with subependymal hemorrhage and periventricular leukomalacia representing the most important examples. The most common intestinal finding, namely, necrotizing enterocolitis, typically shows segmental alterations, the morphology of which largely depends on the dominating causative agent. Hepatic cholestasis and fatty change are mostly consequences of parenteral nutrition or hypoxic/ischemic stress. Hepatic necrosis can be associated with the latter, but may also indicate disseminated intravascular coagulation. Vascular pathomorphology is represented by thromboembolic lesions, in most instances corresponding to sequelae of neonatal management.
