Abstract
Neonatal brain disorders consist of a wide chapter including brain malformations, hypoxic-ischemic encephalopathy, intracranial infections, perinatal trauma and metabolic encephalopathies. The aim of this review paper is to describe the main imaging modalities (ultrasonography, CT, MRI) that are used extensively for the diagnosis of neonatal brain disorders, with their respective advantages and limitations, to illustrate and describe the main brain lesions encountered in the neonatal period, particularly with MRI since its role has increased over the recent years. We will focus on hypoxic-ischemic encephalopathy, materno-fetal infections, metabolic encephalopathies and stroke, those four conditions being the most frequent so far. Imaging modalities, especially MRI, by showing the extent of brain damage, are part of the prognostic factors in cases of infective causes and of hypoxic-ischemic origin. MRI is also very efficient in showing brain damage as atrophy and white matter abnormalities suggestive of an underlying abnormal brain of metabolic origin.

Abstract
Plasmin is essential for metalloproteases activation, endothelial cell migration and degradation of the extracellular matrix. The process is common to neoangiogenesis pannus formation and cartilage degradation within arthritic joints. Since 80% of synovial cells express urokinase plasminogen activator receptor (uPAR), we investigated the inhibition of plasmin activation in a collagen-induced arthritis (CIA) mice model, by expressing a uPA/uPAR antagonist molecule (ATF) fused to human serum albumin (HSA) to extend its serum half-life. Overexpression was obtained with an adenoviral vector expressing the chimeric murine ATF-HSA. We showed that the genetic coupling did not significantly reduce the ability of the ATF moiety to interact with its receptor uPAR. The chimeric protein was detectable in the sera of injected mice 7 days following Ad-mATF-HSA injection, then decreased in parallel with the anti-HSA titer increase. Systemic Ad-mATF-HSA injection performed on day 25 following CIA induction decreased the incidence of arthritis and the severity of the disease. Moreover, synovial angiogenesis in arthritic paws was decreased after Ad-mATF-HSA gene transfer, as assessed by smooth muscle actin immunostaining. The preventive effect observed on arthritis was related to the decrease in angiogenesis, rather than inhibition of extracellular matrix degradation.

Abstract
How far providing neonatal intensive care to extremely low birth weight infants is appropriate is still a highly controversial issue. Decision making when a poor prognosis has been established may be facilitated by consensus based recommendations and rigorous procedures. In the very majority of situations, the provision of intensive care is advocated at birth a priori. A decision of treatment withholding or withdrawal may eventually be made secondarily, in the case major neurological complications, likely to induce severe long term deficits, are evidenced. In any case, an ethical policy focused on each infant's best interest is justified, while the adoption of a systematic, gestational age or birth weight based restriction of access to intensive care may not be acceptable in most countries. Rigorous criteria must be fulfilled for end of life decision making and procedures. Continuous assistance to the patient and to the parents is key determinant.

Abstract
OBJECTIVE The imbalance between matrix metalloproteinases (MMPs) 1, 3, and 9 and their specific inhibitor, tissue inhibitor of metalloproteinases 1 (TIMP-1), is a critical step in cartilage injury and angiogenesis in arthritis. To explore the therapeutic potential of TIMP-1 gene transfer in erosive arthritis, the effects of an adenoviral vector (Ad-TIMP-1) were assessed in DBA/1 mice with collagen-induced arthritis (CIA). METHODS DBA/1 mice with CIA received an intravenous injection of replication-deficient adenovirus containing the human TIMP-1 gene or a control LacZ gene on day 28 postimmunization. The efficiency of gene transfer was determined by serum TIMP-1 detection, measurements of paw swelling, as well as radiologic and histologic examination of the paws. RESULTS A single administration of Ad-TIMP-1 resulted in detectable serum levels of the exogenous protein for at least 13 days. The incidence and onset of arthritis were not statistically modified after human TIMP-1 gene transfer in DBA/1 mice compared with control mice. However, the severity of inflammation was statistically significantly increased in Ad-TIMP-1-treated mice and a similar trend was observed in the histologic and radiologic scores. With regard to the mechanisms of the worsened effect in the Ad-TIMP-1-treated mice, we observed 1) higher serum levels of anti-type II collagen IgG2a, 2) a significant increase in endogenous soluble tumor necrosis factor receptor I (TNFRI) in sera, and 3) increased labeling of mouse tumor necrosis factor alpha and TNFRI within arthritic joints. CONCLUSION These findings show that overexpression of TIMP-1 does not prevent osteochondral injury in a mouse model of arthritis. Since MMPs have overlapping properties in terms of their roles in extracellular matrix degradation, angiogenesis, and shedding of cell surface adhesion molecules, cytokines, and cytokine receptors, the paradoxical results obtained suggest that TIMP-1 is probably not the main inhibitor to target.

Abstract
The aim of this prospective study was to evaluate the predictive significance of magnetic resonance imaging (MRI) performed at 4 months of corrected age in 60 neonates after a perinatal neurologic insult. Follow-up ranged from 2 to 5 years of chronological age. MRI examination was normal in 10; isolated external hydrocephalus was found in 15 infants. Twenty-three of these infants developed normally. Focal or multifocal lesions were shown in 6 infants, of whom 2 developed normally. Diffuse brain involvement was present in 29 cases as atrophy (n = 18), leukomalacia (n = 5), basal ganglia lesions (n = 3), and delayed myelination (n = 3). All but 4 infants showed neurologic impairment. MRI performed at 4 months of adjusted age is of prognostic significance in neonates who suffer a moderate or mild neurologic insult.

Abstract
Environmental tobacco smoke interacts with the respiratory mucosa by irritation and/or inflammation. Environmental tobacco smoke seems also modulate humoral and cellular immune activity. Thus, environmental tobacco smoke, in all children, increases the risk of superior and inferior airway infections, modifies the growth and the natural evolution of the respiratory function, increases the occurrence of asthma and exacerbates the symptoms of asthma, and creates or exacerbates a bronchial hyperresponsiveness. In atopic children (defined by the presence of at least one positive allergy skin test), environmental tobacco smoke increases the risk of respiratory allergy and exacerbates the symptoms of respiratory allergy. Parental environmental tobacco smoke is a universal toxic which must be avoided in both allergic and non-allergic children.

Abstract
The newborn immune system differs quantitatively and functionally from adults. At birth, the immune system is partially immature, resulting in deficiency in cell-mediated cytolysis, immunoglobulin synthesis and cytokine production. The most clearly defined deficit in neonatal phagocytosis defenses is diminished neutrophil storage. T cell function is diminished, including T cell-mediated cytotoxicity and T cell help for B cell differentiation. Selective decreases in cytokine production by T cells may contribute to all of these deficits. One of the fundamental differences between adults and newborns for T cell functions resides in whether or not the patient had prior exposure to antigens. Significant immune responses to antigens can be obtained in the neonatal period. These responses are qualitatively different from those induced in adults with a predominance of TH2 pattern.

Abstract
Colony counting and DEFT did not give the same results when wine micro-organisms were enumerated. Both methods were used to monitor the population of acetic acid bacteria (AAB) and lactic acid bacteria (LAB) during wine storage. Results suggest that part of the populations had reached a viable but non-culturable (VBNC) state. These cells were unable to produce colonies but could hydrolyse fluorescent esters and could be counted by DEFT. For AAB, O2 deprivation quickly induced this state. Recovery from this state was very rapid as soon as O2 was available. The response was not so clear for LAB during wine storage. However, a similar state was induced by sulfiting. Moreover, filtration of wine stored in barrels and contaminated by Brettanomyces, AAB and LAB demonstrated that cell size was not homogeneous. Cells which remained in wine after several weeks could pass through a 0.45-microm membrane. However, when they re-entered a growing phase, they were again retained by membrane filtration. During and after the decline phase, wine micro-organisms might survive as smaller cells in a VBNC state.

Abstract
State-anxiety has been defined as a transitory emotional response involving unpleasant feelings of tension and apprehensive thoughts. Trait-anxiety, on the other hand, has been defined as a personality trait referring to individual differences in the likelihood that a person would experience state anxiety in a stressful situation. The aim of the present study was to assess trait and state-anxiety in a population of patients consulting physicians for anxious complaints. Thus, patients who stopped the benzodiazepine (BZD) treatment after three months and those who continued it for six months were compared. Included patients were evaluated at inclusion (D0), after three months (M3) and after six months (M6). The investigator filled the Covi anxiety scale, the Raskin depression scale and a CGI; patients were asked to fill the Spielberger state/trait-anxiety questionnaire. 1,112 patients have been included, 48% considered their anxiety as chronic, 50% said the evolution was progressive, 87% considered it resulting of a trigger factor, 69% received a benzodiazepine (BZD) treatment. At D0: Covi anxiety score was 5.3 +/- 2.3 points, STAI I (state-anxiety) score was 57.4 +/- 12.2 points and STAI II (trait-anxiety) score was 52.7 +/- 10.2 points. At M3, all scores decreased, and 85% were considered as ameliorated, but differences were significant (p = 0.0001) at M6. When comparing at D0 patients who stopped BZD treatment at M3 and those who continued it, some differences appeared. In fact subjects who stopped the treatment had lower score at the STAI II, presented significantly less flushes (p = 0.01), less tremor (p = 0.04) and less feverishness (p = 0.05). Their score at Covi tended to be lower (p = 0.11). The severity of the disease, evaluated with the CGI, was also lower for the patients who stopped the BZD treatment. The trait-anxiety appeared as a good predictor of the efficacy of the BZD treatment. In fact, the trait-anxiety refers to a tendency to be anxious and higher anxiety necessitates longer treatment. The treatment response was less important in the patients who continued the treatment at M3, indicating the presence of residual anxiety in these patients.

Abstract
The effect of 3 dosages of bromazepam administered as single oral doses (1.5, 3 and 6 mg) on anxious inhibition phenomena was studied in a population of 16 young women (18-30 years) with anxiety-traits, selected on the criteria of Cattell's anxiety scale supported by two personality inventory (Eysenck's, MMPI). A double-blind, placebo study design was chosen. The main assessment criteria were based on the go/no-go test (Logan's procedure), slow response rate (SRR) and a task of forced or unforced decision (use of the CFF). Attentional processes and declarative memory were analyzed as secondary criteria. None of the three dosages modified inhibition or acting-out. Sustained attention was reduced with 1.5 mg and 6 mg, as was memory performance with 3 and 6 mg, 3.5 h after drug administration. In contradistinction with studies carried out in healthy volunteers or with other benzodiazepine compounds, bromazepam at single low dosages does not modify inhibition capacity in these subjects with traits of anxiety, in this particular procedure.

Abstract
The onset of action (during the first 2 weeks of treatment) of moclobemide (450 mg/day), a reversible MAO-A inhibitor, was compared in a double-blind, multi-center trial with clomipramine (150 mg/day) on dimensional and global depressive symptoms in 124 hospitalized patients suffering from a major depressive episode according to DSM-III-R criteria and with blunted affect and retardation. An earlier efficacy was found for moclobemide with significant treatment differences in favor of moclobemide, which were detected on negative symptoms (anhedonia, blunted affect and retardation) on days 7 and 10. The overall effect on depression at the end of the 4-week trial period was similar in both groups. However, a higher termination rate due to lack of efficacy was found with moclobemide (10 vs. 3). The tolerability was significantly better for moclobemide, as shown by the lower frequency of adverse events.

Abstract
The Stüve-Wiedemann syndrome (SWS) comprises short stature, congenital bowing of the long bones, respiratory distress, and recurrent episodes of unexplained hyperthermia. The skeletal radiographic changes include short and broad long bones, large metaphyses, internal cortical thickening, and angulation primarily of tibiae and femora, but also of humeri and forearm bones. We report 3 cases of SWS from 2 different unrelated consanguineous gypsy families. All 3 cases fulfilled the clinical and radiological criteria of SWS. Two patients died shortly after birth, whereas the third one was alive at the age of one year. Besides hyperthermic episodes, one patient had hyperaminoaciduria, hepatic failure, and megaloblastic anemia which prompted us to investigate mitochondrial respiratory chain in 2 cases. Abnormal results consisting of decreased activities of complex I and IV were found in both. The simultaneous occurrence of both SWS phenotype and abnormal mitochondrial metabolism in two unrelated cases strongly supports the hypothesis of a pathogenetic relationship between the two events. These cases may also be related to recent reports on the effects of the mitochondrial respiratory chain defects on embryogenesis.

Abstract
BACKGROUND Polymorphonuclear elastase is an early and sensitive indicator of neonatal infection when performed at the beginning of clinical symptoms. PATIENTS AND METHODS To investigate the diagnostic value of elastase measurement in cord blood immediately after birth, 211 neonates (103 boys vs 108 girls, 154 vaginal delivery vs 57 cesarean section). Mean gestational age 38.9 weeks (range: 30-42), mean birth weight 3,260 g (range: 1,430-4,920 g). After clinical, bacterial and biological screening, the infants were classified in three groups. Group A (n = 118): none infectious risk factor neither clinical signs of infection; group B (n = 79): one or more risk factors but no evidence of infection; group C (n = 14): proved or probable infection. Polymorphonuclear elastase was measured in cord blood of all infants using an heterogeneous enzyme-linked-immunosorbent assay. RESULTS We observed higher elastase values in group C (176 +/- 67 micrograms/L) than in group A (91 +/- 64 micrograms/L) and B (67 +/- 61 micrograms/L) (mean +/- SD, P = 0.0001). With a cutoff value fixed at 80 micrograms/L, the sensitivity of this test applicated to neonates presenting materno-fetal infectious risk factor(s) was 85% (12/14), specificity 74% (59/79), positive predictive value 37%, and negative predictive value 96%. CONCLUSION Because two of the 14 infected infants (15%) were not detected by elastase dosage in cord blood, this test cannot be used as an early indicator of materno-fetal infection.

Abstract
BACKGROUND Indication for intubation and mechanical ventilation in premature infants may be reduced by initiating continuous positive airway pressure (CPAP) in delivery room. POPULATION AND METHODS Immediately after birth, respiratory support with CPAP was given to all infants with gestational age less than 32 weeks. In case of apnea or progressing symptoms with hypoxemia or carbonic acidosis, with PCO2 increasing to more than 60 mmHg, infants were treated with nasotracheal intubation and ventilation. RESULTS One hundred and fifty one infants, with mean gestational age 29.6 +/- 1.9 weeks and mean birth weight 1,326 +/- 378 g were delivered in the obstetrical department of Marseille. In delivery room, 63% were treated with CPAP, and only 13% with nasotracheal intubation. The need for subsequent mechanical ventilation was reduced to 40% of the population. Surfactant therapy was used in 17% of this cohort. Two infants were given surfactant and extubated. Three of 14 deaths (9.2%) were caused by respiratory disease. CONCLUSIONS Early CPAP reduces the indication of mechanical ventilation in premature infants. Incidence of pulmonary complications such as pneumothorax or bronchopulmonary dysplasia is low among those infants who require mechanical ventilation later. Early CPAP takes place in a general policy to decrease neonatal morbidity.
