Cuzzolin","doi":"10.7363/030253","DOIUrl":"https://doi.org/10.7363/030253","url":null,"abstract":"Drug dosage in the perinatal period represents a continuous challenge for the neonatologist because of interindividual variability of drug metabolism. The human liver plays a central role in the uptake, transport, metabolism and excretion of the vast majority of xenobiotics and drugs. The protein products of human CYP3A account for the largest portion of CYP450 proteins in human liver. At least 50% of currently used drugs in neonatal intensive care units (NICUs) are substrates of CYP3A4 including antibiotics, antivirals, antifungals, immunomodulators, benzodiazepines, proton pump inhibitors, steroid hormones and acetaminophen. The variable CYP3A4 and CYP3A7 expression recently reported in neonatal liver suggests the existence of a marked interindividual variability in drug metabolism during the intrauterine and neonatal lives and, as a consequence, the need of an individualized tailored therapeutic approach in NICUs. The increased risk for adverse effects reported for some drugs in neonates could be related to pharmacokinetic peculiarities of the newborn liver. The fetal and neonatal liver in infants undergoing drug-induced liver injury (DILI) is always characterized by the overlapping between developmental and pathological changes, the differential diagnosis between these changes representing often a challenge for the pathologist. Data here reported clearly evidence the peculiarity of the histological examination of the newborn liver, as compared to the adult liver. In conclusion, the role of the pathologist in the interpretation of liver reactions to drugs may be relevant, only when supported by the dialogue with neonatologists. A deep knowledge of the events taking place during liver development at different gestational ages is necessary for a dedicated neonatal pathologist, in order to avoid misinterpretation of the histological changes related to liver development, giving them a pathological significance.

Faa","doi":"10.7363/030265","DOIUrl":"https://doi.org/10.7363/030265","url":null,"abstract":"One of the most severe events occurring in critically ill patients admitted to a neonatal intensive care unit (NICU) center is represented by the multiple organ failure (MOF), a systemic inflammatory response leading to a progressive organ dysfunction and mortality in newborns. MOF may occur in newborns primarily affected by multiple single organ diseases, including respiratory distress syndrome neonatal sepsis with acute kidney injury, post-asphyxial hypoxic-ischemic encephalopathy and pandemic influenza A (H1N1) infection. In a previous article from our group, based on the histological examination of all organs at autopsy of newborns affected by MOF, all organs studied did not escape to be damaged, including thymus and pancreas normally not mentioned in the literature of MOF. The aim of this article is to review the most important pathological changes pathologists should look for in every case of MOF occurring in the perinatal period, with particular attention to systemic endothelial changes occurring in blood vessels in all organs and sytems. On the basis of our experience, matching data during the last phases of the clinicopathological diagnosis represents a useful method, much more productive as compared to the method based on giving pathological answers to the clinical questions prospected before autopsy. As for the pathological features observed in neonatal MOF, one of them deserves a particular attention: the vascular lesions, and in particular the multiple changes occurring during MOF development in endothelial cells, ending with the loss of the endothelial barrier, probably the most relevant histological lesion followed by the insurgence of interstitial edema and disseminated intravascular coagulation. Small vessels should be observed at high power, with particular attention to the size and shape of endothelial nuclei, in order to evidence endothelial swelling, probably the initial modification of the endothelial cells leading to their death. Finally, only the clinical pathological discussion may lead to a good diagnosis, correlating the morphological evidences with the clinical history and the sequence of clinical events that, at the best of our experience, are always different in a new case of MOF.

It is made more serious by its morbidity and mortality rates. Although recent advances in clinical practice (prenatal steroids, surfactants, new ventilatory strategies, nutritional support) have contributed to improving the clinical course and outcomes of neonates with BPD, its overall incidence has not changed in the last decade owing to a concomitant increase in survival of prematures. The incidence of BPD is in fact inversely proportional to birth weight: 30% for neonates weighing less than 1,000 g, with different percentages in the single centres depending on clinical management and the ventilation criteria applied. However, to date, BPD represents not only a chronic pulmonary pathology in infancy that prevalently affects premature neonates who undergo mechanical ventilation and oxygen therapy for respiratory distress syndrome (RDS), but also prematures with minor signs of initial pulmonary pathology or term neonates requiring aggressive ventilatory support due to an acute and severe lung pathology.

Hypoxia and ischemia is probably the commonest type of acquired brain damage in preterm infants. The clinical manifestations of hypoxic-ischemic injury in survivors of premature birth include a spectrum of cerebral palsy and intellectual disabilities. Until recently, the extensive brain abnormalities in preterm neonates appeared to be related mostly to destructive processes that lead to substantial deletion of neurons, axons, and glia from necrotic lesions in the developing brain. Advances in neonatal care coincide with a growing body of evidence that the preterm gray and white matter frequently sustain less severe insults, where tissue destruction is the minor component. Periventricular leukomalacia (PVL) is the major form of white matter injury and consists classically of focal necrotic lesions, with subsequent cyst formation, and a less severe but more diffuse injury to cerebral white mater, with prominent astrogliosis and microgliosis but without overt necrosis. With PVL a concomitant injury occurs to subplate neurons, located in the subcortical white matter. Severe hypoxic-ischemic insults that trigger significant white matter necrosis are accompanied by neuronal degeneration in cerebral gray and white matter. This review aims to illustrate signs of cerebral embryology of the second half of fetal life and correlate hypoxic-ischemic brain injury in the premature infant. This should help us better understand the symptoms early and late and facilitate new therapeutic strategies.

Described causative factors for MODS in the neonatal period are sepsis, shock due to any cause, tissue hypoperfusion, prematurity, hypoxic ischemic encephalopathy, necrotizing enterocolitis (NEC), surgery, congenital heart disease and others. MOF can be considered as the final common pathway of immunological, cytokine and hormonal changes, occurred as physiologic re- sponse to different infectious or non-infectious inflammatory insults, who lead to systemic inflammation, a procoagulant state and progressive organ dysfunction. The clinical presentation of MODS can widely vary, depending on the primary causes, nature, number and severity of the organ systems involved. Pre-MODS conditions should be promptly identified and treated. In case of severe sepsis and septic shock, the available guidelines should be followed. When MODS already occurred, supportive care for single organ dysfunction should be provided and adequate oxygenation and organ perfusion maintained. More studies in term and preterm infants (with the development of specific neonatal scoring systems) are needed, to further understand neonatal MODS and assess strategies for early prevention and treatment.

Faa","doi":"10.7363/030255","DOIUrl":"https://doi.org/10.7363/030255","url":null,"abstract":"Hyaline membrane disease (HMD), the pathologic correlate of respiratory distress syndrome (RDS) of the newborn, is an acute lung disease of premature infant caused by inadequate amounts of surfactant. Decreased surfactant results in insufficient surface tension in the alveolus during expiration, leading to atelectasis, decreased gas exchange, severe hypoxia and acidosis. HMD predominantly occurs in infants younger than 32 weeks of gestation and weighing less than 1,200 g. In the interpretation of perinatal lung pathology, it is necessary to consider the development of the immature lung, particulary in the third trimester. Microscopically HMD is characterized by the occurrence of dilated terminal and respiratory bronchioles and of alveolar ducts lined by acellular eosinophilic hyaline membranes. The membranes are composed of necrotic alveolar lining cells, amniotic fluid constituents and fibrin. Retinopathy of prematurity and bronchopulmonary dysplasia are late complications of RDS that usually occur in infants who weigh less than 1,500 g and were maintained on a mechanical respiration more than 6 days. Here a pratical approach to a microscopic analysis of the lung in newborns died with the clinical setting of RDS is presented. The most important pathological findings for a complete clinical pathological diagnosis are: the evaluation of the architectural lung development; the endothelial cell lesions; the interstitial edema; the occurrence of disseminated intravascular coagulation; the presence of associated inflammatory lesions. The usefulness of some immunohistochemical stains is also underlined, including anti-surfactant, anti-smooth muscle actin and anti-CD31 to better evaluate surfactant production, pulmonary artery maturation and endothelial cell damage, respectively. Finally, the prevalent role of endothelial dysfunction and endothelial barrier loss is underlined, representing a major pathological event in the deposition of HMD.
