[Diagnosis, pathogenesis and treatment of attention deficiency syndrome]. / Diagnostika, patogenez i lechenie sindroma defitsita vnimaniya.

Attention deficit hyperactivity disorder is the dominant form of cognitive and behavioral dysfunctions in childhood, the disease has a chronic course and manifests in adolescents and adults in 50-80% of cases. An adequate diagnosis is the testing of parents and teachers using the Conners questionnaire in two stages, the second is mandatory after 6 months to confirm the persistence of symptoms over time. The pathogenesis is based on violations of mediation of dopamine and norepinephrine in the fronto-striate-thalamic system, responsible for the function of constant attention, caused by molecular genetic mechanisms. Atomoxetine (Cognitera) in combination with pedagogical and psychological methods of correction seems to be an adequate drug for many months of use, taking into account international and Russian experience of use.

[Development of speech disorders in children]. / Narusheniya razvitiya rechi u detei.

The function of the formation of speech skills is decisive in the development of a child in communication and assimilation of information. Early pediatric diagnosis should become a routine practice of monitoring children from infancy to school age for the timely correction of speech disorders and associated dysgraphia and dyslexia. According to the ICD-10 classification, speech developmental disorders are divided into the following options: articulation impairment, delay in expressive and impressive speech. Articulation disorders, stuttering, impaired expressive speech are the most common and most favorable prognosis for speech therapy interventions. The data on the effectiveness of disorders of the receptive (impressive) language are ambiguous, since there is a high likelihood of a combination with neurogenetic diseases and autism. The development of speech therapy programs will make it possible to broader coverage of those in need of treatment, including complex course therapy with neuropeptides (cortexin).

[Alternating hemiplegia with epilepsy]. / Al'terniruyushchaya gemiplegiya, assotsiirovannaya s epilepsiei.

A clinical case of a genetically confirmed diagnosis of alternating hemiplegia associated with epilepsy is presented. The combination of two types of seizures in a child made it difficult to make a diagnosis. The result of video-EEG monitoring made it possible to understand that a child showed both epileptic seizures and non-epileptic seizures simultaneously with different periodicities. The mutation in the ATP1A3 gene was verified with genome-wide sequencing and targeted therapy was prescribed in a timely manner. As a result, both types of seizures stopped after treatment.

[Clinical and neuroimaging signs of cardioembolic stroke laboratory in children]. / Klinicheskie i neirovizualizatsionnye priznaki kardioémbolicheskogo insul'ta u detei.

AIM: To study clinical and neuroimaging signs of cardioembolic stroke (CES) in children. MATERIAL AND METHODS: Ten children (mean age 3.5±3.5 years) were examined. Eight children met the diagnostic criteria of CES CASCADE, two children were diagnosed with CES based on the complex of symptoms. A comparison group consisted of 90 children with other subtypes of ischemic stroke (IS). The diagnosis was confirmed by MRI and magnetic-resonance angiography; symptom severity was assessed with PedNIHSS and PSOM. RESULTS AND CONCLUSION: The PedNIHSS score in the acute stage of CES was higher (18.4±9.34) compared to patients with other subtypes of IS (12.6±6.2; p=0.0065). Six patients had large cerebral infarctions with the involvement of basal ganglia, internal capsule, white matter and cerebral cortex. In two patients, the infarction affected the cerebral cortex and underlying white matter, in one patient it affected the cortex from one side and the basal ganglia from the other. A damage of the cortex was noted in one patient. The frequency of recurrent CES was 30%, of fatal cases 20%. Recurrent IS and severe residual neurological deficit were more frequent in CES. CONCLUSION: Early disease onset, acute development and progression of neurological deficit up to the maximal level in the first 5 min, marked severity of the acute stage (PedNIHSS score >15), early onset of neurological function recovery, marked residual neurological deficit (PSOM score >2) are the additional signs of CES.

AIM: To study clinical and neuroimaging signs of cardioembolic stroke (CES) in children. MATERIAL AND METHODS: A group of 100 patients with arterial ischemic stroke (AIS), aged from 1 month to 15 years, was stratified into the main group (10 patients with CES) and the comparison group (90 patients with other subtypes of AIS). CT and MRI, MR-angiography, ultrasound study as well as assessment of clinical symptoms on PedNIHSS were performed. The duration of follow-up was from 2 month to 14 years. The follow-up allowed the assessment of occurrence of secondary strokes, severity of residual neurological symptoms on the PSOM and fatal outcomes. Special attention was drawn to the use of CASSADE criteria for CES. RESULTS AND CONCLUSION: Clinical features that help to diagnose CES, even in the absence of adequate neuroimaging, in patients with heart disease, which is a potential high risk factor for cardioembolia, were established. These factors include early disease onset, acute development and progression of neurological deficit to the maximal level in the first 5 min., marked severity of the acute period (PedNIHSS > 15), early recovery of neurological functions, significant residual neurological symptoms (PSOM > 2). These symptoms should be used in addition to the CASCADE criteria in the diagnosis of CES of AIS type in children.

[Arterial ischemic stroke in children with mild head trauma]. / Arterial'nyĭ ishemicheskiĭ insul'ta u deteĭ s legkoĭ travmoĭ golovnogo mozga.

AIM: To study the relationship between mild head trauma (MHT) and arterial ischemic stroke (AIS) in children. MATERIAL AND METHODS: We examined 81 patients with AIS, aged from 1 month to 15 years. The sample was stratified into two groups: patients with AIS caused by MHT (main group) and patients without MHT (comparison group). RESULTS AND CONCLUSION: Based on the results of clinical and instrumental studies, we identified the relationship between AIS and MHT. The main group was characterized by the following features: moderate severity in the acute period, stabilization within 7 days, isolated subcortical localization of ischemic lesion, no MRI-signs of steno-occlusive cerebral arteriopathy and a trend towards the risk of recurrent strokes.

[Classification system CASCADE for childhood arterial ischemic stroke].

In this review, a new consensus-based classification system for childhood arterial ischemic stroke CASCADE (2012) is described. The CASCADE is an anatomically based classification system which offers the specific diagnostic interventions and suggests the unified terminology. So, it can be used both in clinical practice and in any research in childhood arterial ischemic stroke.

[Secondary prevention of ischemic stroke in children].

Pediatric arterial ischemic stroke (IS) is an important cause of lifelong disability. Arteriopathies due to trauma and infection are an important underlying cause of childhood arterial ischemic stroke. The secondary prevention of IS should be conducted taking into account the main pathogenetic mechanisms and vascular risk factors. For secondary stroke prevention, the majority of children are treated with either anticoagulation or antiplatelet therapies. This review focuses on the recent international clinical recommendations in secondary stroke prevention based on the results of randomized multicenter clinical studies published by the USA. cardiology association. Experience of anticoagulation or antiplatelet therapies for secondary stroke prevention is insufficient in Russia. Taking into account the available international recommendations is expedient for creation and practical application of the Russian standards for secondary arterial ischemic stroke prevention.

[Prothrombotic disturbances in children after ischemic stroke].

Thirty-six patients with stroke, aged from 8 months to 15 years, and 28 control children, aged 1-15 years, were studied. In both groups, the evaluation of anamnesis, neurologic status and genotyping for 11 most common prothrombotic polymorphisms were carried out. Coagulogram tests and measurement of homocysteine were performed before the anticoagulant therapy in the main group. The total frequency of prothrombin gene mutations (G20210A, factor V Leiden, MTHFR C677T and MTRR A66G) was 2.8 times higher in the main group compared to the control one. The most frequent genotypes were 677TT (8.3% of cases) and 66GG (30.6%). In patients with stroke, the homocysteine level exceeded the upper limit of normal age and also was significantly elevated in carriers of abovementioned risk genotypes: 10.29 +/- 1.55 mcmol/l vs 7.33 +/- 0.6 mcmol/l (p = 0.018). The coagulogram revealed disorders of anticoagulant system, including the decrease of protein C activity (22.7% of cases), protein S activity (13.6%) and antithrombin III (12.5%) and the increase of D-dimer level (21% of cases). It has been suggested to screen for common prothrombotic states and measure homocysteine levels in children with ischemic stroke and to lower homocysteine levels by using vitamins B6 and B12' and diet.

[Diagnostics of ischemic stroke in children: a literature review and an analysis of clinical cases].

Ischemic stroke in children is a multidisciplinary problem which is based on various etiological factors. The establishment of diagnosis is complex and demands, besides the ascertainment of cerebral infarction by neuroimaging methods, the use of different tests for determination of the main disease. In Russia, the causes of IS in children are elucidated in about 40% of cases. The most plausible causes of the restricted diagnostics are the insufficient knowledge of physicians about etiological factors of this disease, absence of diagnostic standards and poor economic and technical support of municipal medical centers for children that do not allow the timely examination of patients in accordance with a brain stroke diagnostic algorithm. Two cases demonstrating as the variety of etiological factors in IS in children as well as the obvious restriction of diagnostic search are presented.

[Autonomic cardiovascular regulation in patients with tics and Tourette syndrome].

Autonomic cardiovascular regulation has been assessed in patients aged 4-15 years with Tourette syndrome (n = 22) and other tic disorders (n = 48). Symptom significance was estimated by a number of hyperkinetic episodes per 20 minutes, tic scale and variants of the disease course. The functional condition of autonomic nervous system was studied clinically and using spectral analysis of heart rate variability in both upright and supine positions. Negative correlation between the ratio of sympathetic and vagus influences and severity of the disease was found: the severer were tic symptoms, the stronger was a trend to vagotonia (beta = -0.36; p < 0.0025; F > 4.0). In orthostatic test, patients with Tourette syndrome demonstrated an unfavorable hypersympathicotonic type of cardiovascular system reaction. Patients were treated during 4 weeks with glycinum (0.2 +/- 0.1 mg/day), phenibutum (0.5 +/- 0.25 mg/day), clonazepam (1.5 +/- 0.5 mg/day), tiapride (200 +/- 100 mg/day), haloperidol (1-1.5 mg/day), rispolept (2 mg/day). There was no negative effect of the drugs on heart rate variability. On the contrary, the therapy reduced hyperkinetic symptoms and corrected autonomic influences on the sinus rhythm. It is suggested that changes in autonomic cardiovascular regulation might be of secondary character and do not need any special correction.

[Efficacy of acupressure therapy in combined treatment of psycho-autonomic neurotic disorders in children]. / Effektivnost' refleksoterapii v kompleksnom lechenii psikhovegetativnykh rasstroistv u detei.

The aim of the study was to evaluate the efficacy of acupuncture in combined treatment of psychoautonomic neurotic disorders in children. 163 children, mean age 12.5 years, were included in the study. Autonomic dysfunction score, clinoorthostatic test, sinocarotid test and heart rate variability analysis were used to assess the efficacy of different therapeutic strategies applied: complex (acupuncture + conventional drug treatment)--group 1; acupuncture treatment--group 2, and conventional drug treatment--group 3. After 2 months of treatment, a reduction of autonomic dysfunction score and an increase of percentage of patients with normal clinoorthostatic and sinocarotid tests were revealed in all the groups, being most evident in group 1. Heart rate spectral variability changed in patients given acupuncture treatment (groups 1 and 2). Relative augmentation of sympathetic activity was observed in patients with initial vagotonia, while those with initial symphaticotonia exhibited a relative parasympathetic activity increase. Thus, acupuncture exerts beneficial effects on functioning of autonomic nervous system. The method may be used either independently, or in addition to conventional drug treatment of psychoautonomic neurotic disorders in children.
