Background: Youth suicide remains a significant public health concern in Japan, driven by multifaceted factors such as academic pressures, social isolation, bullying, and family dysfunction. Recent societal changes, including the rise of internet addiction and subcultural influences from anime, manga, and gaming, have further shaped the psychological landscape of Japanese youth. The COVID-19 pandemic has exacerbated these challenges, intensifying feelings of loneliness and anxiety about the future. Methods: This study explores the impact of these factors on youth suicide risk through a systematic review of existing literature and statistical data, focusing on trends from 2000 to 2024. Results: In 2023, 513 school-aged youth in Japan died by suicide, marking persistently high rates. High school students accounted for the majority of cases, followed by middle and elementary school students. Key risk factors include intense academic expectations, cyberbullying, and internet addiction, which are often compounded by cultural stigmas surrounding mental health. Subcultures offer both solace and potential alienation, influencing youth emotions in complex ways. The COVID-19 pandemic has also worsened mental health issues and heightened suicide risks among this vulnerable group. Conclusions: The findings highlight the urgent need for comprehensive mental health support systems tailored to Japanese cultural contexts. Recommendations include enhancing access to school-based counseling, promoting family-based interventions, and implementing policies to regulate harmful online content. Additionally, efforts must address cultural attitudes that stigmatize mental health care. Collaborative societal and policy-level interventions are crucial for mitigating youth suicide and fostering a supportive environment for young people in Japan. [ABSTRACT FROM AUTHOR]

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). mTOR inhibitors, notably everolimus, have become central to TSC management, with documented efficacy in reducing the sizes of SEGAs and AMLs and showing promise in addressing additional TSC-related symptoms. Case Presentation: We report the case of an 11-year-old male diagnosed with TSC, presenting with hallmark features including hypopigmented macules, early-onset infantile spasms, SEGA, and AMLs. Initial interventions included adrenocorticotropic hormone (ACTH) therapy and sodium valproate for seizure management and a minimally invasive keyhole craniotomy for SEGA reduction. At age 12, oral everolimus therapy was introduced to address both SEGA recurrence risk and ASD-related social deficits. Over the course of 24 weeks, a reduction in the size and erythema of the patient's FAs was observed, alongside improvements in social engagement, suggesting potential added benefits of systemic mTOR inhibition beyond tumor control. Results: Treatment with everolimus over a 24-month period led to significant reductions in both FA and AML size, as well as measurable improvements in ASD-associated behaviors. Therapeutic drug monitoring maintained serum levels within the effective range, minimizing adverse effects and underscoring the tolerability and feasibility of long-term everolimus administration. Conclusions: This case underscores the efficacy of oral everolimus in reducing FA size in a pediatric TSC patient, with broader therapeutic benefits that support the potential of mTOR inhibition as a multi-targeted strategy for TSC management. Further studies are needed to explore the full range of applications and long-term impact of mTOR inhibitors in TSC care. [ABSTRACT FROM AUTHOR]

Background: We report a rare case highlighting the progression of liver disease in a male patient with idiopathic childhood-onset growth hormone (GH) deficiency. Case presentation: The patient was diagnosed with hypopituitarism at six years old and was treated with thyroxine therapy and GH for his short stature, with testosterone added at the age of 15. GH therapy was discontinued when the patient was 18 years old, but thyroid and testosterone treatments continued. The patient had been taking medication for hyperlipidemia until the age of 30 and was noted to have impaired glucose tolerance at the age of 40, but HbA1c levels remained normal. At the age of 47, esophageal varices were incidentally discovered via endoscopy, revealing liver cirrhosis. Laboratory tests showed liver dysfunction and abnormal lipid levels, and hepatitis viral markers were absent. The patient had no history of drinking alcohol or smoking, and no family history of diabetes. Results: Ultimately, this case demonstrates that metabolic dysfunction-associated steatotic liver disease (MASLD/metabolic dysfunction-associated steatohepatitis (MASH)) is under-recognized in GH deficiency cases and can progress to liver cirrhosis. Conclusions: Therefore, careful evaluation of MASLD/MASH in childhood-onset GH deficiency is necessary, and GH replacement therapy should continue into adulthood, if possible. [ABSTRACT FROM AUTHOR]

The number of people immersed in excessive gaming has increased in this age of rapid digitalization. The World Health Organization and American Psychiatric Association Organization recognize a gaming disorder as a condition that results in significant problems in daily life as a result of excessive gaming. Both organizations emphasize the similarities to behavioral addictions such as gambling. We examined the appropriate usage of video games from the perspectives of health and management in this study. For the general population, video games provide positive impacts such as stress alleviation and memory improvement. Game playing leads to a loss of time and money for the individual. It also has a negative impact on the individual's family and social life, evolving into a social problem. Gaming addiction is often accompanied by psychological disorders and other addictions, and long-term medical treatment, including approaches to the individual's psychological background and cognitive-behavioral therapy, is necessary. Therefore, the prevention of gaming disorder is essential. From a societal standpoint, action is required in three contexts: the government, game developers, and within the household as a whole. Simultaneously, the public needs to understand the positive potential of gaming, such as e-sports. [ABSTRACT FROM AUTHOR]

Pseudohypoparathyroidism (PHP) is a rare disorder characterized by convulsions, tetany, and sensory abnormalities caused by hypocalcemia due to parathyroid hormone (PTH) resistance. Only few patients present with involuntary movements. We report the case of a 7-yr-old girl with PHP and involuntary movements triggered by running. Initially, she was suspected of having paroxysmal kinesigenic dyskinesia and was treated with carbamazepine (CBZ). Involuntary movements were reduced. However, 2 months post-treatment, she experienced convulsions during a fever. Blood tests and brain computed tomography revealed hypocalcemia, hyperphosphatemia, elevated intact PTH, and calcifications in the frontal cortex and basal ganglia. The patient showed no features of Albright's hereditary osteodystrophy. The involuntary movements disappeared after the discontinuation of CBZ and initiation of calcium and active vitamin D preparations. Methylation-specific multiplex ligation-dependent probe amplification for the GNAS region and microsatellite analysis of chromosome 20 led to the diagnosis of PHP1B caused by epimutation. In 15 reported cases, with or without intracranial calcification, PHP-associated involuntary movements disappeared or became less severe with treatment for hypocalcemia; in eight of 11 cases, they were triggered by exercise or movement. PHP-associated hypocalcemia can trigger exercise-induced involuntary movements owing to lowered serum ionized calcium levels. In such patients, early blood tests are vital for the differential diagnosis of PHP. [ABSTRACT FROM AUTHOR]
