BACKGROUND/AIMS: Patients with mild traumatic brain injury (mTBI) on anticoagulants have an increased risk of intracranial hemorrhage (ICH). However, consensus is lacking on whether to admit them after normal initial cranial CT. We evaluated the yield of 24-h neurological observation. METHODS: Retrospective multicenter study including adult patients admitted over a 5-year period with mTBI on anticoagulation [therapeutic dose heparin, direct oral anticoagulant, or vitamin K antagonist (VKA) with international normalized ratio (INR) ≥ 1...

BACKGROUND: Early life adversity (ELA) is not uncommon in Major Depressive Disorder (MDD) patients. Childhood trauma has been reported more frequently in adult MDD patients relative to healthy control. Recent researches have demonstrated that ELA could result in changes in brain morphology which might be an etiological factor of MDD development. MATERIALS AND METHODS: We recruited 40 young adult patients suffered from MDD and made CT scan. Subjects were divided in two groups: MDD patients with ELA experience (E+D) vs MDD patients without ELA experience (E-D) according to Chinese version-Childhood Trauma Questionnaire (CTQ)...

Sepsis-induced brain injuries increase mortality, morbidity, cognitive impairment and lack of effective therapeutic treatment. Previous studies have suggested that metformin provides neuroprotective effects against ischemia, brain trauma and other brain damage, but whether metformin protects a septic brain remains unknown. Thus, the aim of this study is to investigate the possible effects and the mechanism of metformin against septic brain damage using the cecal ligation and puncture (CLP) model. Mice were randomly divided into five groups: the Sham group, CLP group, CLP+ Met group, CLP+ vehicle group and CLP+ Met+ LY group...

OBJECTIVE: Childhood trauma is common and associated with both worse cognitive performance and disruption to the hypothalamic-pituitary-adrenal axis in younger adults. The extent to which these associations persist into older adulthood remains unknown. The aim of this study was to investigate self-reported childhood trauma in relation to cognitive performance, and the extent to which cortisol explained this association, in 2 independent samples of older adults. METHODS: In this cross-sectional study, participants in the discovery sample (N = 76) consisted of older adults with a DSM-IV diagnosis of generalized anxiety disorder (N = 57) and age-equated psychiatrically healthy comparison subjects (N = 19) who were referred largely through primary care clinics between 2004-2006...

Sexual assault is a traumatic event with potentially devastating lifelong effects on physical and emotional health. Sexual assault is associated with gastrointestinal, neurologic, and reproductive symptoms, as well as obesity, diabetes, and chronic pain. With 1 in 3 women and 1 in 6 men experiencing some form of unwanted sexual violence in their lifetime, sexual assault is a significant public health problem that necessitates attention in the medical community. This review discusses relevant literature on the neurobiologic changes that occur as a consequence of sexual assault, such as how the brain responds during a traumatic experience and the impact of trauma on memory...

Unexpected foreign bodies are occasionally discovered during magnetic resonance imaging (MRI). These are often present unknown to the patient, missed during routine pre-MRI screening and result in unnecessary delay during MRI. The authors present a patient with traumatically embedded foreign body in the scalp that escaped pre-MRI screening and caused susceptibility artifacts during brain MRI. The object was surgically removed to allow the imaging to be completed. Patients with suspicion or history of facial trauma or with dental restorations are referred to concerned specialists for compatibility of hardware, restorations and for assessing risks during MRI due to these...

BACKGROUND: Trauma is an eminently preventable disease. However, prevention programs divert resources away from other priorities. Costing trauma related diseases helps policy makers to make decisions on re-source allocation. We used data from a prospective digital trauma registry to cost Traumatic Brain Injury (TBI) at our institution over a two-year period and to estimate the funding gap that exists in the care of TBI. METHOD: All patients who were admitted to the Pietermaritzburg Metropolitan Trauma Service (PMTS) with TBI were identified from the Hybrid Electronic Medical Registry (HMER)...

BACKGROUND: Rib fractures and flail chests have traditionally been treated nonoperatively. Current literature suggests that it is not only safe and feasible but also desirable to perform fixation of severe rib fractures. Our unit in the Pietermaritzburg public sector adopted rib fracture fixation in 2014 and in this audit we assess its feasibility in our setting. METHODS AND RESULTS: We audited our first nine cases of rib fracture fixation performed to date, of which seven were males...

Neural activity is an important biomarker for the presence of neurodegenerative diseases, cerebrovascular alterations, and brain trauma; furthermore, it is a surrogate marker for treatment effects. These pathologies may occur and evolve in a long time-period, thus, noninvasive, transcutaneous techniques are necessary to allow a longitudinal follow-up. In the present work, we have customized noninvasive, transcutaneous, diffuse correlation spectroscopy (DCS) to localize changes in cerebral blood flow (CBF) induced by neural activity...

In the mature adult skeleton, new bone formation is normally restricted to regeneration of osseous tissue at sites of fracture. However, heterotopic ossification, or the formation of bone outside the normal skeleton, can occur within muscle, adipose, or fibrous connective tissue. Periarticular non-hereditary heterotopic ossification (NHHO) may occur after musculoskeletal trauma, following CNS injury, with certain arthropathies, or following injury or surgery that is often sustained in the context of age-related pathology...

Childhood maltreatment, including abuse and neglect, may have sustained effects on the integrity and functioning of the brain, alter neurophysiological responsivity later in life, and predispose individuals toward psychiatric conditions involving socioaffective disturbances. This meta-analysis aims to quantify associations between self-reported childhood maltreatment and brain function in response to socioaffective cues in adults. Seventeen functional magnetic resonance imaging studies reporting on data from 848 individuals examined with the Childhood Trauma Questionnaire were included in a meta-analysis of whole-brain findings, or a review of region of interest findings...

Scientific literature suggests a relationship between military occupation and the development of brain tumors, but no italian study has investigated on the impact of this job on the brain cancer morbidity. In this a study information were obtained from patients recruited in the Neurosurgical Department of the University-Hospital of Pisa, Italy, from 1990 to 1999. The study has been conducted as a case-control study. 161, newly diagnosed cases of brain tumors (glioma and meningiomas, histologically confirmed), were recruited, such as 483 controls (with other non tumoral neurologic diseases: trauma, hemorrhagic brain disorders, aneurism, etc), by matching cases and controls (1:3), for age (± 5 years) and gender...

Abusive head trauma (AHT) is the leading cause of death from trauma in infants and young children. An AHT animal model was developed on 12-day-old mice subjected to 90° head extension-flexion sagittal shaking repeated 30, 60, 80, and 100 times. The mortality and time until return of consciousness were dependent on the number of repeats and severity of the injury. Under 60 times of repeated head shakings, the pups demonstrated apnea and/or bradycardia immediately after injury. Acute oxygen desaturation was observed by pulse oximetry during respiratory and cardiac suppression...

BACKGROUND Improving quality and effectiveness of healthcare is one of the priorities of health policies. Hospital or physician volume represents a measurable variable with an impact on effectiveness of healthcare. An Italian law calls for the definition of «qualitative, structural, technological, and quantitative standards of hospital care». There is a need for an evaluation of the available scientific evidence in order to identify qualitative, structural, technological, and quantitative standards of hospital care, including the volume of care above or below which the public and private hospitals may be accredited (or not) to provide specific healthcare interventions...
