BACKGROUND: The preterm newborn is at high risk of developing cardiovascular compromise during the first day of life and this is associated with increased risk of brain injury. Standard treatments are volume expansion and administration of inotropes, typically dopamine and/or dobutamine, but there is limited evidence that inotropes improve clinical outcomes. This study investigated the efficacy of dopamine and dobutamine for the treatment of cardiovascular compromise in the preterm newborn using a piglet model...

OBJECTIVE: Neonatal deaths account for 44% of the world's under-5 child mortality. Over half of all neonatal deaths globally occur in preterm babies. Therefore, improving care of a preterm baby is particularly important to reduce under-5 mortality. The objective of this study was to spell out components of care of preterm/low birth weight babies at first level health facility and at first referral unit (FRU) in low resource settings. STUDY DESIGN: We have analyzed weight-wise survivals at two hospitals attached to medical colleges, J...

Dopamine is often used to treat hypotension in preterm infants; these infants are at risk of developing brain injury due to impaired autoregulation and cerebral hypoperfusion. However the effects of dopamine on the immature brain under conditions of cerebral hypoxia are not known. We hypothesized that pretreatment with dopamine would protect the immature brain from injury caused by cerebral hypoxia. Preterm fetal sheep were used to determine the effects of intravenous dopamine on hypoxia-induced brain injury...

BACKGROUND: Autoregulatory dysfunction is an important contributor to brain injury in premature infants, particularly intraventricular hemorrhage (IVH). The autoregulatory system acts as a filter that dampens the systemic blood flow to follow a normal cerebral perfusion profile. METHODS: Simultaneous arterial blood pressure and cerebral near-infrared spectroscopy (NIRS) data were collected from infants born before 28 wk estimated gestational age. The resulting data were preprocessed and then divided into nonoverlapping 20-min epochs...

The determination of dopamine facilitates better understanding of the complex brain disorders in the central nervous system and the regulation of endocrine system, cardiovascular functions and renal functions in the periphery. The purpose of this study was to develop a highly sensitive and reliable assay for the quantification of dopamine in human neonate plasma. Dopamine was extracted from human plasma by strong cation exchange (SCX) solid phase extraction (SPE), and subsequently derivatized with propionic anhydride...

Shock is characterized by inadequate oxygen delivery to the tissues, and is more frequent in very low birth weight infants, especially in the first few days of life. Shock is an independent predictor of mortality, and the survivors are at a higher risk of neurologic impairment. Understanding the pathophysiology helps to recognize and classify shock in the early compensated phase and initiate appropriate treatment. Hypovolemia is rarely the primary cause of shock in neonates. Myocardial dysfunction is especially common in extremely preterm infants, and in term infants with perinatal asphyxia...

A woman with a prolactinoma is usually infertile. Dopamine agonists usually restore ovulation and fertility and such treatment generally is preferred over transsphenoidal surgery because of higher efficacy and safety. Cabergoline is usually preferred over bromocriptine because of its better efficacy with fewer adverse effects. Either drug increases the rates of spontaneous abortions, preterm deliveries, multiple births, or congenital malformations over what may be expected. However, the number of pregnancies reporting such experience is about sevenfold greater for bromocriptine...

BACKGROUND: The perfusion index (PI) derived from pulse oximetry readings represents the ratio of pulsatile (arterial blood) and nonpulsatile contributors to infrared light absorption. PI has been shown to correlate with cardiac performance. In theory, PI is readily available on every pulse oximeter; therefore, no additional sensors or infant handling are required. Currently, reference values are lacking in (preterm) neonates and the association with common clinical conditions is unclear...

Prenatal stress and depression affects 10-25% of pregnant women and is associated with disruption of fetal neurodevelopment, higher rates of placental abnormalities, preeclampsia, spontaneous abortion, or preterm birth. Markers of genetic vulnerability are catechol-O-methyltransferase, monoamine oxidase-A, variation of serotonin transporters, low levels of dopamine-beta-hydroxylase, and brain derived neurotrophic factor Val66Met (BDNF), while hyperactivity of HPA (hypothalamic-pituitary-adrenal) axis and massive release of endogenous cortisol, regulated by metalloproteinase-1, -2, -3 and -9, and are involved both in depressive symptoms and neurodevelopmental abnormalities in fetus...

OBJECTIVE: Transient neonatal hyperthyrotropinemia (TNH) is defined as a neonatal abnormality of thyroid function, which reverts to normal at re-examination after 2 weeks of life. The thyroid function of these infants has not been sufficiently studied in terms of the risk of developing persistent hyperthyrotropinemia (PH) in later childhood and its impact on growth and development. DESIGN: A prospective cohort study included all babies born in our hospital between 2001 and 2006 and screened for hypothyroidism, whose thyroid function was re-examined 6 years later...

AIM: Hypotension is a common problem in newborn infants and is associated with increased mortality and morbidity. Dopamine is the most commonly used antihypotensive drug therapy, but has never been shown to improve neurological outcomes. This study tested our hypothesis that dopamine affects cerebral autoregulation (CA). METHODS: Near-infrared spectroscopy was used to measure the cerebral oxygenation index in 60 very preterm infants, and mean arterial blood pressure was monitored towards the end of their first day of life...

OBJECTIVE: We performed a multicenter study of preterm infants, who were about to undergo patent ductus arteriosus ligation, to determine whether echocardiographic indices of impaired myocardial performance were associated with subsequent development of catecholamine-resistant hypotension following ligation. STUDY DESIGN: A standardized treatment approach for hypotension was followed at each center. Infants were considered to have catecholamine-resistant hypotension if their dopamine infusion was > 15 μg kg(-1)min(-1)...

Hyperprolactinemia, frequently caused by a prolactinoma, is an important cause of infertility among young women. Dopamine agonists (DA) are the treatment of choice. Although cabergoline (CAB) is currently considered the gold standard DA, bromocriptine (BRC) remains the drug of choice for women desiring pregnancy, as it was proven to be safe in more than 6,000 pregnancies. The purpose of this review is to perform a critical evaluation of CAB safety in pregnancy, as it is used by most patients harboring prolactinomas...
