Background: Comorbidity of Internet addiction (IA) with sleep disruptions is common in adolescents. There is evidence that the levels of brain injury markers could be affected by sleep disruptions. In this study, we aimed to evaluate the relationship between sleep quality and these biomarkers within the framework of the relationship between IA and sleep disruptions.
Methods: A total of 65 drug-free adolescents with newly diagnosed IA, aged 12 to 18 years, were included in the study, and they were divided into two groups considering the comorbidities of attention-deficit/hyperactivity disorder (ADHD) and social anxiety. The control group consisted of 30 healthy children. The participants were asked to complete the Young Internet Addiction Scale, Pittsburgh Sleep Quality Index (PSQI), Morningness Eveningness Questionnaire, Beck's Depression Inventory, Beck's Anxiety Inventory, and Barratt Impulsiveness Scale-11. Blood samples were taken between 8 and 9 am to analyze S100 calcium-binding protein B (S100B) and neuron-specific enolase (NSE) levels with enzyme-linked immunosorbent assay.
Results: Plasma S100B and NSE levels were found to be statistically significantly higher in the IA with ADHD and the IA with anxiety groups than in healthy controls. NSE and S100B levels were found to be correlated with PSQI scores in both the IA groups. Also, there was a positive correlation between these biomarkers and IA severity.
Conclusions: Decreased sleep quality and daily sleep duration in IA might cause brain injury, resulting in an increase in the severity of the addiction. Prospective studies with large samples are needed to better explain the IA-sleep-brain injury relationship.

Injury to one cerebral hemisphere can result in paresis of the contralesional hand and subsequent preference of the ipsilesional hand in daily activities. However, forced use therapy in humans can improve function of the contralesional paretic hand and increase its use in daily activities, although the ipsilesional hand may remain preferred for fine motor activities. Studies in monkeys have shown that minimal forced use of the contralesional hand, which was the preferred hand prior to brain injury, can produce remarkable recovery of function.

Delayed cerebral ischemia, one of the most common complications following aneurysmal subarachnoid hemorrhage, was strongly related to poor patient outcomes. However, there are currently no clear guidelines to provide clinical guidance for post-craniotomy management. Our research aims to explore the association between cumulative blood pressure exposure during the early brain injury phase and the occurrence of delayed cerebral infarction and rebleeding following surgical aneurysm clipping.

The METH use can lead to addiction, which has become a worldwide problem, resulting in a slew of public health and safety issues. Recent studies showed that chronic METH use can lead to neurotoxicity, neuro-inflammation and oxidative stress which can lead to neuronal injury.

Background: Lung transplantation is a viable lifesaving option for patients with diffuse pulmonary arteriovenous malformations (AVMs). We present a case of diffuse pulmonary AVMs associated with juvenile polyposis and hereditary hemorrhagic telangiectasia (JP-HHT) that was successfully managed by lung transplantation.
Case Presentation: A 19-year-old woman developed severe hypoxemia due to pulmonary AVMs diagnosed at 4 years of age.
