Facial angiofibroma is the characteristic symptom and also a major diagnostic criterion for Bourneville-Pringle disease. The centrofacially localized hamartomatous tumours start to appear in early childhood, and progress over time. Facial angiofibromas represent a significant cosmetological problem for the patients and a therapeutic challenge for the physician. Beside the traditional invasive treating methods, topical sirolimus is a new, promising and well-tolerated treatment modality. Several studies and case reports have been published on this new therapeutic approach, but recommendation for the optimal sirolimus concentration still does not exist. We report here two cases when children were successfully treated with topical sirolimus. Orv Hetil. 2019; 160(13): 516-520.

Selective deletion of from mouse cerebellar Purkinje neurons drives sex-specific behavioral impairments linked to autism.
Front Behav Neurosci
December 2024
Department of Biology, Miami University, Oxford, OH, United States.
Article Synopsis
- There is a significant sex bias in autism spectrum disorder (ASD), with 80% of cases diagnosed in males, making it challenging to uncover the biological reasons behind this difference.
- Loss of function mutations leading to dysregulated mTORC1 signaling are prevalent in individuals with tuberous sclerosis (TSC), and over 50% of those with TSC are also diagnosed with ASD, indicating a strong genetic link.
- In experiments with mice, it was found that while motor coordination deficits are similar in both male and female mice, social interaction impairments are significantly worse in males, suggesting that certain behavioral issues in ASD may vary based on sex.
Lymphangioleiomyomatosis of the Pelvic Lymph Nodes Detected Incidentally During Surgical Staging of Gynecological Malignancies: Comprehensive Clinicopathological Analysis of 17 Consecutive Cases from a Single Institution.

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.

Sci Rep

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).
