White matter and reading deficits after pediatric traumatic brain injury: A diffusion tensor imaging study.
Pediatric traumatic brain injury often results in significant long-term deficits in mastery of reading ability. This study aimed to identify white matter pathways that, when damaged, predicted reading deficits in children. Based on the dual-route model of word reading, we predicted that integrity of the inferior fronto-occipital fasciculus would be related to performance in sight word identification while integrity of the superior longitudinal fasciculus would be related to performance in phonemic decoding. ⋯ No association was identified between the inferior fronto-occipital fasciculus and sight word reading or phonemic decoding. Reading fluency was associated with the integrity of the cingulum bundle. These findings support dissociable pathways predicting word reading and fluency using Diffusion Tensor Imaging and provide additional information for developing models of acquired reading deficits by specifying areas of brain damage which may predict reading deficits following recovery from the acute phase of TBI.

Prevalence of mental health conditions after military blast exposure, their co-occurrence, and their relation to mild traumatic brain injury.
To measure common psychiatric conditions after military deployment with blast exposure and test relationships to post-concussion syndrome (PCS) symptoms and mild traumatic brain injury (mTBI) history. ⋯ These findings support that psychiatric conditions beyond PTSD are common after military combat deployment with blast exposure. They also highlight the non-specificity of post-concussion type symptoms. While some researchers have implicated mTBI history as a contributor to post-deployment mental health conditions, no clear association was found. This may partly be due to the more rigorous method of retrospective mTBI diagnosis determination.

How long is too long? The lack of consensus regarding the post-concussion syndrome diagnosis.
A standard definition of Post-concussion Syndrome (PCS) does not exist. The objective was to determine consensus regarding the definition of PCS among physician members of the American College of Sports Medicine (ACSM). ⋯ There is a lack of consensus regarding the definition of PCS among physician members of the ACSM. A standard definition would improve consistency in concussion research and in clinical practise.

Cognitive and self-reported psychological outcomes of blast-induced mild traumatic brain injury in veterans: a preliminary study.
The increased use of explosives in combat has resulted in a large number of returning veterans suffering from blast-related mild traumatic brain injury (mTBI) and self-reported complications. It remains unclear whether this increase in self-reported difficulties is unique to the blast mechanism or stressful preinjury environment and whether cognitive-functioning deficits correspond with these difficulties in the postacute phase. This study examined the relationship between cognitive performance and self-reported psychological and somatic symptoms of blast-related mTBI compared with civilian mTBI, independent of comorbid posttraumatic stress disorder (PTSD) symptoms. ⋯ Overall, preliminary results suggest that in the postacute phase, subjective complaints related to blast-related mTBI do not covary with objective cognitive performance. Additionally, cognitive outcomes from blast-related mTBI were similar to those of civilian forms of mTBI. Future studies should identify the cognitive and self-reported sequelae of blast-related mTBI independent of comorbid PTSD in a larger sample of veterans.

Barbiturate coma therapy (BCT) is a choice treatment for refractory intracranial hypertension after all surgical or medical managements have failed to control the intracranial pressure (ICP). It helps to reduce cerebral blood flow, cerebral metabolic rate of oxygen consumption and ICP. ⋯ One of the underreported, but life-threatening complications is refractory hypokalemia, which can lead to subsequent rebound hyperkalemia after sudden cessation. We report our experience of managing unusual complication of refractory hypokalemia during BCT with thiopentone in postdecompressive craniectomy patient.
