Brain metastases from thyroid carcinoma is unusual, with a frequency of 1%. We report twelve patients, with single brain metastases and with a karnofsky performance scale score >60 at admission. No metastasis was seen during the uptake of iodine-131, even in the cases from differentiated thyroid carcinoma, suggesting absence of differentiation between… (More)
Cerebral meningiomas are rare tumors in children that represent 1.4% of CNS tumors and 1.5% of intracranial meningiomas. We have analyzed 197 cases of cerebral meningiomas under 16: 178 cases were taken from the available literature and 19 from our series. When comparing pediatric meningiomas with those of adults, we noted some differences. Before the age… (More)
BACKGROUNDS Nerve growth factor (NGF) is involved in the modulation of the neuro-endocrine-immune (NEI) system, whereas alterations in neuroplasticity and NEI homeostasis seem to play a role in the pathophysiology of major depressive disorder (MDD). Objective of the study was to investigate NGF levels variations in MDD patients during antidepressant… (More)
It has been frequently reported that brain-derived neurotrophic factor (BDNF) plays an important role in the pathophysiology of major depressive disorder (MDD). Objective of the study was to investigate BDNF levels variations in MDD patients during antidepressant treatment with duloxetine. 30 MDD patients and 32 healthy controls were assessed using Hamilton… (More)
INTRODUCTION The cortical midline structures seem to be involved in the modulation of different resting state networks, such as the default mode network (DMN) and salience network (SN). Alterations in these systems, in particular in the perigenual anterior cingulate cortex (PACC), seem to play a central role in bipolar disorder (BD). However, the exact role… (More)
Neurotransmitters and hormones regulate major immune functions, including the selection of T helper (Th)1 or Th2 cytokine responses, related to cell-mediated and humoral immunity, respectively. A role of imbalance and dynamic switching of Th1/Th2 system has been proposed, with relative displacement of the immune reserve in relation to complex interaction… (More)
Neurinomas of the hypoglossal nerve extending extra-cranially are rare; a schwannoma in a 63-year-old woman causing nerve palsy is reported. The tumour presented as a slow-growing mass in the right submandibular space; a surgical approach with transcervical exploration was performed. The post-operative course was uneventful.
BACKGROUND In patients submitted to suboccipital craniectomy in whom the bone is not repositioned, there may be a significant aesthetic defect due to lack of bone tissue, sometimes accompanied by paresthaesia and painful symptoms. METHOD In 15 patients submitted to suboccipital craniectomy, the bone chips were repositioned during wound closure. FINDINGS… (More)
We report a case of missile injury to the brain with an unusual complication. The bullet migrated by its mere weight to a distant location through the brain parenchyma after initially lodged in a superficial site. Movement of the bullet was first detected on CT scan and the significance and treatment of this finding is emphasized.
