Introduction. The frequency of post-traumatic hydrocephalus is 3.9%. The incidence of post-traumatic defects of the skull is 10.46 per 100,000 per year. Overdrain syndrome occurs in 1012% of cases in patients with long-term ventricular shunting. The presence of a cranial defect causes a violation of blood flow and cerebrospinal fluid dynamics in the area of the defect, a displacement of brain structures under the influence of gravity and atmospheric pressure, which can cause a deterioration in the patients condition and a significant slowdown in recovery after a severe head injury. Both craniotomy syndrome and excessive shunting can impede the verticalization and rehabilitation of patients with post-traumatic hydrocephalus and post-traumatic defects of the bones of the cranial vault. Description of the clinical case. Clinical case demonstrates an example of a differential approach and an algorithm for deciding on surgical treatment in a patient with post-traumatic hydrocephalus and cranial bones defect in case of deterioration during attempts at verticalization in a complex of rehabilitation measures. Conclusion. The clinical manifestations of trephine skull syndrome and syndrome of shunt overdrain in the patient after severe traumatic brain injury combines post-traumatic hydrocephalus, may be similar. And not always, as demonstrated in this clinical case, narrowed ventricles and the relationship of deterioration to verticalization should be interpreted as a syndrome of excessive drainage of the shunt system. The plastic surgery of the defect of the bones of the cranial vault performed in this case made it possible to improve the patients condition and regress symptoms.

Critically ill patients often develop hyperglycemia because of the metabolic response to trauma and stress. In response to any form of damage to the organism, it reacts by increasing its own glucose production which subsequently causes hyperglycemia. This adaptive reaction of the organism is directed to aid in the rapid restoration after the damage. Therefore, glucose is an indispensable substrate in the critically ill which aids the reparation process. Severe and persistent hyperglycemia is associated with unfavorable outcomes and is considered to be an independent predictor of in-hospital mortality. The discussion remains on whether hyperglycemia is just a marker of increased stress which makes it a surrogate indicator of disease severity or if it is the reason for the unfavorable outcome. A few years ago, several published articles suggested that a tight glycemic control within the normal range improves treatment outcome. Over time, researchers have changed their point of view and currently there is a discussion on this matter in the scientific literatures. At the same time, the question of what glycemic level should be maintained for patients in the Neurological Intensive Care Unit is a matter of discussion. In this review, the authors analyzed the latest guidelines on treatment of critical patients with neurosurgical and neurological pathologies, specifically the glycemic control in this category of patients.
