One of the complications of the postoperative period in children is postanesthetic agitation, a significant emotional and uncontrollable worry, clouding of consciousness, feeling of anxiety and fear, inappropriate behavior, irritability, inconso­lable crying, aggressive and negative attitude towards parents and medical staff. Postoperative agitation is very important for clinicians and hospitals, it has a risk of harming a patient, staying longer in the ward after anesthesia, and increasing the period of postoperative recovery. The frequency of postoperative agitation depends on age group. Most often agitation occurs in young children. There is evidence that agitation can also be due to the immature nervous system and a consequence of pathological conditions of the central nervous system (asthenoneurotic syndrome, encephalopathy, hyperactivity syndrome, perinatal posthypoxic and organic brain lesions, history of prematurity, epilepsy, psychophysical and speech delay, etc.). That is why the goal of our research was to study the patterns of clinical manifestations of postoperative agitation syndrome in children with prenatal da­mage to the central nervous system. The work was performed based on the analysis of the postoperative period in 109 young children: 59 patients with acquired hydrocephalus, who underwent ventriculoperitoneal shunting, and 50 children without neurological disorders in whom reconstructive surge­ries were carried out. Depending on the type anesthetic management, each group was divided into two subgroups: children, who received inhalation anesthesia with sevoflurane, and those, who received total intravenous anesthesia using propofol. In the postoperative period, the behavior of children was assessed on a Pediatric Ane­sthesia Emergence Delirium scale 30 minutes after anesthesia was completed. Criterion for the development of agitation was the presence of excitement in a child with a score of ≥ 10 points. Study showed that young children with perinatal damage to the central nervous system and children whose anesthetic provision is carried out using sevoflurane are the most vulnerable to the development of agitation syndrome. Agitation in such children is more pronounced and longer. These cases require prediction, detection and active surveillance.

Different organs can be affected secondary to sickle cell disease, including the central nervous system, kidneys, gastrointestinal tract, respiratory system, cardiovascular system, bone, and joints. This can lead to increased morbidity and mortality events among the affected patients. Osteoarticular complications represent a severe set of events for patients with sickle cell disease. These complications might include gouty, septic, juvenile, and erosive arthritis, dactylitis, bone infarction, and osteomyelitis. These are the most common complications reported in the literature, and some case reports even reported other types of complications that develop secondary to the previously mentioned ones. Adequate diagnosis might be challenging in some cases. Therefore, clinicians must be crucial in determining the appropriate clinical and radiographic manifestations. Treating these cases is also challenging. Consequently, clinicians should be aware of these complications to enhance the prognosis of the affected patients. Further research is needed for the standardization of the diagnostic and management approaches in these events.

Abstract With advances in brain imaging and completion of randomized clinical trials (RCTs) for primary and secondary stroke prevention, the natural history of central nervous system (CNS) complications in sickle cell disease (SCD) is evolving. In order of current prevalence, the primary CNS complications include silent cerebral infarcts (39% by 18 years), headache (both acute and chronic: 36% in children with sickle cell anemia [SCA]), ischemic stroke (as low as 1% in children with SCA with effective screening and prophylaxis, but ∼11% in children with SCA without screening), and hemorrhagic stroke in children and adults with SCA (3% and 10%, respectively). In high-income countries, RCTs (Stroke Prevention in Sickle Cell Anemia [STOP], STOP II) have demonstrated that regular blood transfusion therapy (typically monthly) achieves primary stroke prevention in children with SCA and high transcranial Doppler (TCD) velocities; after at least a year, hydroxycarbamide may be substituted (TCD With Transfusions Changing to Hydroxyurea [TWiTCH]). Also in high-income countries, RCTs have demonstrated that regular blood transfusion is the optimal current therapy for secondary prevention of infarcts for children with SCA and strokes (Stroke With Transfusions Changing to Hydroxyurea [SWiTCH]) or silent cerebral infarcts (Silent Infarct Transfusion [SIT] Trial). For adults with SCD, CNS complications continue to be a major cause of morbidity and mortality, with no evidence-based strategy for prevention.
