Observation's analysis of 5 children in age from 9 months to 4 years 11 months with tuberous sclerosis was performed. The initial manifestations of disease were following: early children form of epilepsy exactly infantile spasms (West syndrome) appearance, dermal alterations in the form of depigmented spots as well as nonprogressive delay in psychoverbal development. Together with clinical symptoms the main criterion in early form of tuberous sclerosis diagnosis determination turned out to be brain's specific alterations (tubers) which were revealed by computer tomography. The correlation was observed between epileptic seizures polymorphism and frequency as well as brain's morphological alterations. Derivatives of valproic acid were the basic drugs in treatment of epileptic seizures in patients.

There is a striking sex bias in the prevalence and severity of autism spectrum disorder (ASD) with 80% of diagnoses occurring in males. Because the molecular etiology of ASD is likely combinatorial, including interactions across multiple genetic and environmental factors, it is difficult to investigate the physiological mechanisms driving sex-specific differences. Loss of function mutations in result in dysregulated mTORC1 signaling and underlie a multi-system disorder known as tuberous sclerosis (TSC).

Background/aim: Lymphangioleiomyomatosis (LAM) belongs to the perivascular epithelioid cell tumor (PEComa) family. The relationship between LAM and tuberous sclerosis complex (TSC) is of particular concern in a subset of women with clinically occult LAM involving the pelvic lymph nodes. This study aimed to investigate the clinicopathological features of incidental nodal LAM detected during the surgical staging of gynecological tumors.

Among the most prevalent are hemophilia A (deficiency of Factor VIII), hemophilia B (deficiency of Factor IX), and von Willebrand disease. Management of pharmacoresistant epilepsy is more difficult in a patient with bleeding disorder due to increased risk of bleeding during surgery.

Network hypersynchrony is emerging as an important system-level mechanism underlying seizures, as well as cognitive and behavioural impairments, in children with structural brain abnormalities. We investigated patterns of single neuron action potential behaviour in 206 neurons recorded from tubers, transmantle tails of tubers and normal looking cortex in 3 children with tuberous sclerosis. The patterns of neuronal firing on a neuron-by-neuron (autocorrelation) basis did not reveal any differences as a function of anatomy.

Background: Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder characterized by mutations in the TSC1 and TSC2 genes, leading to the dysregulation of the mammalian target of rapamycin (mTOR) pathway. This dysregulation results in the development of benign tumors across multiple organ systems and poses significant neurodevelopmental challenges. The clinical manifestations of TSC vary widely and include subependymal giant cell astrocytomas (SEGAs), renal angiomyolipomas (AMLs), facial angiofibromas (FAs), and neuropsychiatric conditions such as autism spectrum disorder (ASD).
