Correlation between voluntary cough and laryngeal cough reflex flows in patients with traumatic brain injury.
To correlate voluntary cough and laryngeal cough reflex (LCR) flows in patients with traumatic brain injury (TBI). ⋯ As LCR can be measured as a numerical value and significantly correlates with PCF, LCR can be used to estimate cough ability of patients with TBI who cannot cooperate with PCF measurement.

Progesterone and vitamin D: Improvement after traumatic brain injury in middle-aged rats.
Progesterone (PROG) and vitamin D hormone (VDH) have both shown promise in treating traumatic brain injury (TBI). Both modulate apoptosis, inflammation, oxidative stress, and excitotoxicity. We investigated whether 21 days of VDH deficiency would alter cognitive behavior after TBI and whether combined PROG and VDH would improve behavioral and morphological outcomes more than either hormone alone in VDH-deficient middle-aged rats given bilateral contusions of the medial frontal cortex. ⋯ Combination therapy showed moderate improvement in preserving spatial and reference memory but was not significantly better than PROG monotherapy. However, combination therapy significantly reduced neuronal loss and the proliferation of reactive astrocytes, and showed better efficacy compared to VDH or PROG alone in preventing MAP-2 degradation. VDH+PROG combination therapy may attenuate some of the potential long-term, subtle, pathophysiological consequences of brain injury in older subjects.

Coagulopathy frequently occurs following traumatic brain injury (TBI) and usually occurs 6-72 hour post-trauma. The incidence and the probable risk factors for development of coagulopathy and poor outcome following TBI are largely unknown and vary considerably. ⋯ There is a high incidence of coagulopathy following TBI. The presence of coagulopathy as well as of severity of TBI are strong predictors of in-hospital mortality in these patients.

Malignant middle cerebral artery infarction (mMCAI) is a life-threatening condition in pediatric patients. Despite strong evidence showing decreased morbidity and mortality in adult mMCAI patients with decompressive hemicraniectomy (DCH), there is a paucity of data on the use of DCH in children with similar conditions. Here we report experience from our center and perform a systematic review of published literature on outcomes after use of DCH in pediatric mMCAI patients. ⋯ The current data suggest a role for DCH in the management of cerebral edema in pediatric patients with mMCAI. Factors that help in prognostication for adult stroke patients undergoing DCH do not appear to convey similar information about the pediatric population. This highlights the urgent need for collaboration across institutes to further investigate this potentially life-saving procedure in pediatric stroke.

[Prognosis in pediatric traumatic brain injury. A dynamic cohort study].
traumatic brain injury is a main cause of hospital admission and death in children. Our objective was to identify prognostic factors of pediatric traumatic brain injury. ⋯ there should be a prognosis established based on kinetic energy of the injury and not only with Glasgow Scale.
