S100B protein, cerebral ultrasound and magnetic resonance imaging patterns in brain injured preterm infants.

Objectives: The early detection of preterm infants (PI) at risk for intraventricular hemorrhage (IVH) and neurological sequelae still constitutes an unsolved issue. We aimed at validating the role of S100B protein in the early diagnosis and prognosis of IVH in PI by means of cerebral ultrasound (CUS) and magnetic resonance imaging (MRI) today considered standard of care procedures.

Methods: We conducted an observational case-control study in 216 PI of whom 36 with IVH and 180 controls.

Antenatal maternal antidepressants drugs treatment affects S100B levels in maternal-fetal biological fluids in a dose dependent manner.

Background: The increased use of antidepressant treatment during pregnancy occurred without firm evidence on safety/efficacy. The present study investigated the correlation among S100B and paroxetine blood levels with the occurrence of short-term post-natal neurological abnormalities.

Methods: We conducted a cross-sectional study in 50 pregnant women using paroxetine because of depression and in 150 controls.

Monitoring the effectiveness of hypothermia in perinatal asphyxia infants by urinary S100B levels.

Background Perinatal asphyxia is a major cause of mortality and morbidity in neonates: The aim of the present study was to investigate, by means of longitudinal assessment of urinary S100B, the effectiveness of hypothermia, in infants complicated by perinatal asphyxia and hypoxic-ischemic encephalopathy. Methods We performed a retrospective case-control study in 108 asphyxiated infants, admitted to nine tertiary departments for neonatal intensive care from January 2004 to July 2017, of whom 54 underwent hypothermia treatment and 54 did not. The concentrations of S100B protein in urine were measured using an immunoluminometric assay at first urination and 4, 8, 12, 16, 20, 24, 48, 72, 96, 108 and 120 h after birth.

[Antiretroviral therapy in inmates: between guidelines and reality of Italian correctional facilities].

In HIV-positive patients detention often represents a unique opportunity for health care. HIV-positive inmates enjoy the same rights as non-restricted people, as established under national and international legislation, declarations and guidelines. Antiretroviral therapy in restricted men shows some peculiarities such as the voluntary non-taking of drugs to worsen the health status or obtain legal benefits and the high frequency of concomitant psychiatric treatment.

Neurological abnormalities in full-term asphyxiated newborns and salivary S100B testing: the "Cooperative Multitask against Brain Injury of Neonates" (CoMBINe) international study.

Background: Perinatal asphyxia (PA) is a leading cause of mortality and morbidity in newborns: its prognosis depends both on the severity of the asphyxia and on the immediate resuscitation to restore oxygen supply and blood circulation. Therefore, we investigated whether measurement of S100B, a consolidated marker of brain injury, in salivary fluid of PA newborns may constitute a useful tool for the early detection of asphyxia-related brain injury.

Methods: We conducted a cross-sectional study in 292 full-term newborns admitted to our NICUs, of whom 48 suffered PA and 244 healthy controls admitted at our NICUs.

Hemihydranencephaly: living with half brain dysfunction.

Hemi-hydranencephaly is a very rare condition characterized by complete or almost near-complete unilateral absence of the cortical cortex, which is filled by a sac of cerebrospinal fluid. Prenatal vascular disruption with occlusion of the carotid artery territories ipsilateral to the damaged brain is the presumed pathogenesis.We have selected nine cases that fit the clinical and pathologic characteristics of hemi-hydranencephaly, demonstrating that destruction of one hemisphere may be not always associated with severe neurologic impairment and may allow an almost normal life.

First intention high-frequency oscillatory and conventional mechanical ventilation in premature infants without antenatal glucocorticoid prophylaxis.

Objective: Data comparing the effectiveness of high-frequency oscillatory ventilation and of conventional mechanical ventilation in the treatment of respiratory distress syndrome of very low birth weight infants are, to date, still matter of debate. We investigated the effects of first intention high-frequency oscillatory ventilation or conventional mechanical ventilation support on selected primary and secondary outcomes in very low birth weight infants complicated by respiratory distress syndrome in which antenatal glucocorticoid prophylaxis was not performed.

Design: Multicenter randomized control trial.

Neuromarkers and unconventional biological fluids.

There is a growing evidence on the use of biomarkers in daily practice both as of markers of brain/multiorgan damage and/or trophic factors. However, among different tools, Activin A, S100B protein, and Hemeoxygenase-1 (HO-1 or Heat Shock Protein 32, HSP32) assessment offer the possibility to investigate brain/multiorgan function and development. This could be especially useful in perinatal medicine that requires even more noninvasive techniques to fulfill the minimal handling diagnostic and therapeutic strategy.

Mycobacterium xenopi pulmonary infection resulting in self-limited immune reconstitution inflammatory syndrome in an HIV-1 infected patient.

Highly active antiretroviral therapy (HAART) has been shown to induce a major and durable viral load reduction accompanied by a stable CD4 increase. This process may evolve with adverse clinical phenomena, known as the immune reconstitution inflammatory syndrome (IRIS). In the HIV population, non-tuberculous mycobacteria are a common cause of IRIS.

Visceral leishmaniasis in a patient with common variable immunodeficiency and evans syndrome: clinical remarks.

Visceral Leishmaniasis (VL) is a vector-borne zoonosis endemic in Southern Italy whose usual clinical features include fever, splenomegaly, pancytopenia and hypergammaglobulinemia. The clinical and biochemical picture may be misleading in patients with immunodeficiency diseases hampering the diagnosis. We describe a VL case in a patient whose spleen had been removed and who had Common Variable Immunodeficiency and Evans syndrome.

S100B milk concentration in mammalian species.

S100B is a neurotrophic protein detectable in biological fluids and in human milk. Since there are several maternal-neonatal conditions requiring the administration of animal milks the aim of the present study was to quantify S100B in milk from different mammalian species and to compare protein's concentration among human and mammalian milks. We assessed S100B concentrations in donkey (n=12), goat (n=15) sheep (n=15), commercially available cow (n=8) and human (n=15) milk samples.

Decreased parietal cortex activity during mental rotation in children with congenital hypothyroidism.

Background: The ability to detect the spatial characteristics of objects and to rotate them mentally is frequently impaired in early treated congenital hypothyroidism (CH) children.

Aims: To explore the neural substrate of the visuospatial difficulty in children with CH, we studied 15 children with CH (8-10 years) and 13 age-matched control children with functional magnetic resonance imaging (fMRI) using a mental rotation task (VST).

Results: Performance at VST was significantly different between the two groups.

S100B Protein concentration in milk-formulas for preterm and term infants. Correlation with industrial preparation procedures.

Human milk S100B protein possesses important neurotrophic properties. However, in some conditions human milk is substituted by milk formulas. The aims of the present study were: to assess S100B concentrations in milk formulas, to verify any differences in S100B levels between preterm and term infant formulas and to evaluate the impact of industrial preparation at predetermined phases on S100B content.

Maternal dietary habits and mycotoxin occurrence in human mature milk.

During 2006, 82 samples of human mature milk were collected at Italian hospitals and checked for aflatoxin M1 (AFM1) and ochratoxin A (OTA) by immunoaffinity column extraction and HPLC. AFM1 was detected in four (5%) of milk samples (ranging from < 7 ng/L to 140 ng/L; mean level: 55.35 ng/L); OTA was detected in 61 (74%) of milk samples (ranging from < 5 ng/L to 405 ng/L; mean level: 30.

Infected atrial myxoma: case report and literature review.

Myxoma is the most common type of cardiac tumour in all age groups. It may simulate infective endocarditis but is rarely infected. We describe one case of infected left atrial myxoma caused by Enterococcus faecalis.
