Objectives: To report the case of a patient diagnosed with tuberous sclerosis complex (TSC), describe its clinical features, diagnosis, and to attract attention on the fact that after 40 years of follow-up, the patient has presented practically all the manifestations described in the literature.
Methods: A 42-year-old man diagnosed with.TSC presented the emergency department due to left lumbar pain and self-limited gross hematuria. On clinical examination patient was haemodynamically stable, but with decrease in haemoglobin (6.8 g/dL). Abdominal CT scan showed a 20 cm diameter heterogeneous mass in the left kidney suggesting hemorrhage of an angiomyolipoma.
Results: Left radical nephrectomy was performed and the pathological study of the surgical specimen confirmed the diagnosis of angiomyolipoma. Inmunohistochemical staining was positive with HMB-45.
Conclusions: To recommend that patients with TSC be evaluated by a multidisciplinary group of clinicians, including urologists, neurologists and dermatologists. As patients with TSC survive into adulthood they will require more intervention by the urologist. CT scan is usually enough for the diagnosis of angiomyolipomas. Complete nephrectomy is appropriate when the whole kidney has been replaced by angiomyolipoma. The identification of molecular markers (HMB-45) facilitates histopathological diagnosis.

As one of the most commonly used general anesthetics (GAs) in surgery, numerous studies have demonstrated the detrimental effects of sevoflurane exposure on myelination in the developing and elderly brain. However, the impact of sevoflurane exposure on intact myelin structure in the adult brain is barely discovered. Here, we show that repeated sevoflurane exposure, but not single exposure, causes hypomyelination and abnormal ultrastructure of myelin sheath in the prefrontal cortex (PFC) of adult male mice, which is considered as a critical brain region for general anesthesia mediated consciousness change.

Objective: This study evaluates the utility of word embeddings, generated by large language models (LLMs), for medical diagnosis by comparing the semantic proximity of symptoms to their eponymic disease embedding ("eponymic condition") and the mean of all symptom embeddings associated with a disease ("ensemble mean").
Materials And Methods: Symptom data for 5 diagnostically challenging pediatric diseases-CHARGE syndrome, Cowden disease, POEMS syndrome, Rheumatic fever, and Tuberous sclerosis-were collected from PubMed. Using the Ada-002 embedding model, disease names and symptoms were translated into vector representations in a high-dimensional space.

Objective: To analyze the first referral service for rare diseases accredited by the Brazilian Ministry of Health, focusing on referral from the primary healthcare network through to diagnosis.
Methods: This is a descriptive study with patients treated between 2016 and 2021 at a referral hospital service located in Curitiba, Paraná, Brazil. Clinical and epidemiological data were obtained from medical records, as were the results of genetic tests at the hospital's clinical analysis laboratory.

Background: Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder affecting multiple organ systems, with a prevalence of 1:6,760-1:13,520 live births in Germany. On the molecular level, TSC is caused by heterozygous loss-of-function variants in either of the genes TSC1 or TSC2, encoding the Tuberin-Hamartin complex, which acts as a critical upstream suppressor of the mammalian target of rapamycin (mTOR), a key signaling pathway controlling cellular growth and metabolism. Despite the therapeutic success of mTOR inhibition in treating TSC-associated manifestations, studies with mTOR inhibitors in children with TSC above two years of age have failed to demonstrate beneficial effects on disease-related neuropsychological deficits.
