Is Low-Grade Intraventricular Hemorrhage in Very Preterm Infants an Innocent Condition? Structural and Functional Evaluation of the Brain Reveals Regional Neurodevelopmental Abnormalities.

BACKGROUND AND PURPOSE: There is increasing evidence of abnormal neurodevelopmental outcomes in very preterm infants with low-grade intraventricular hemorrhage grades I and II. Our purpose was to evaluate the effects of low-grade intraventricular hemorrhage on gray and white matter integrity. MATERIALS AND METHODS: MR imaging at around term-equivalent age was performed in 16 very preterm infants (mean gestational age, 28.8 ± 5.3 weeks) with mild intraventricular hemorrhage on brain sonography and 13 control subjects (mean gestational age, 29.6 ± 4.1 weeks) without intraventricular hemorrhage. Structural and functional evaluation of the cortex was performed using regional measurements of surface area, thickness and volume, and resting-state fMRI, respectively, and of WM microstructural integrity, applying Tract-Based Spatial Statistics to diffusion tensor imaging data. RESULTS: Compared with the control infants, the infants with low-grade intraventricular hemorrhage had decreases in the following: 1) GM surface area in Brodmann areas 19 left and 9 and 45 right, and GM volume in Brodmann areas 9 and 10 right; 2) fractional anisotropy bilaterally in major WM tracts; and 3) brain activity in the left lower lateral and in the right higher medial somatosensory cortex. CONCLUSIONS: Very premature infants with low-grade intraventricular hemorrhage at around term-equivalent age may present with regional abnormalities, appearing on imaging studies as cortical underdevelopment, functional impairment, and microstructural immaturity of major WM tracts.

Duloxetine-induced hypomania: case report and brief review of the literature on SNRIs-induced mood switching.

Manic switching during antidepressant treatment has been reported with every class of antidepressant drugs. Serotonin-noradrenaline reuptake inhibitors (SNRIs) have been increasingly used for the treatment of unipolar and bipolar depression and are well tolerated and sufficiently effective because of their dual mechanism of action. A case of duloxetine-induced hypomania in a non-bipolar patient is presented, and a brief review of all cases of SNRIs' induced mania and hypomania has been carried out. The available data suggest that SNRIs, especially venlafaxine, can induce mood switching in patients with bipolar depression and in certain patients with unipolar depression, but the potential of duloxetine and milnacipran to induce manic or hypomanic symptoms cannot be disregarded. Switching appears to be dose-related and treatment initiation with lower doses and upward titration when needed may be preferable in selected cases and may help minimizing the risk of mood switching.

The contribution of a mobile mental health unit to the promotion of primary mental health in rural areas in Greece: a 2-year follow-up.

During the 2 years of the mobile mental-health unit's operation in Northwestern Greece, the referrals increased rapidly with 29.4% of patients never having received mental-health care before, while hospitalizations and relapses reduced significantly, indicating that community-oriented programs can contribute greatly to successfully addressing the needs of patients in remote rural areas.
