Abstract

Skin aging is a progressive degenerative process characterized by a decline in the structural and functional capacity of the skin to maintain its protective, regenerative, and homeostatic roles. It is influenced by both intrinsic factors, such as genetics, telomere shortening, mitochondrial dysfunction, hormonal changes, microbiota alterations, and decreased vitamin D production, and extrinsic factors, including ultraviolet radiation, pollution, smoking, oxidative stress, and lifestyle. Clinically, skin aging presents with thinning, dryness, loss of elasticity, fine to deep wrinkles, pigmentary changes, and benign skin lesions. The increasing elderly population, particularly in Indonesia, highlights the growing importance of addressing skin aging due to its impact not only on physical health but also on psychosocial well-being and quality of life. Management strategies include pharmacological approaches such as sunscreens, moisturizers, vitamin D and collagen supplementation, retinoids, and hormone replacement therapy, as well as non-pharmacological interventions including antioxidant-rich nutrition, hydration, allergen avoidance, wound care, dietary restriction, facial massage, and aesthetic procedures like stem cell therapy. Early prevention, timely recognition, and comprehensive management of skin aging are essential to support healthy aging and maintain the quality of life among the elderly.

Abstract

Hypothyroidism is a condition in which the thyroid gland is unable to produce enough hormones to meet the body's needs. This condition causes a slowed metabolism, which can lead to various symptoms such as fatigue, weight gain, dry skin, hair loss, constipation, cold intolerance, and facial puffiness. Given the widespread impact of hypothyroidism and the potential for serious complications, special attention is needed for early detection, diagnosis, and effective treatment of hypothyroidism. This literature review was conducted using journal review methods and data searches through sources such as PubMed, Google Scholar, and ScienceDirect. The search used the keywords "hypothyroidism," "hypothyroid," "thyroid gland," and "Hashimoto's thyroiditis." The results of the literature review found that the main cause of hypothyroidism is Hashimoto's thyroiditis, an autoimmune disease in which antibodies attack the thyroid gland. Hypothyroidism is diagnosed by examining elevated TSH and decreased free T4 levels, as well as anti-TPO antibody tests to detect Hashimoto's thyroiditis. Treatment for hypothyroidism generally involves administering levothyroxine, a synthetic thyroid hormone, to replace the deficient hormone and normalize metabolic function. Healthy lifestyle support, such as diet and stress management, is also important to help optimally manage this condition. In conclusion, hypothyroidism is characterized by a decrease in thyroid hormone production and preventive management is pharmacological in the form of levothyroxine, while non-pharmacological management is in the form of regulating food intake.

Abstract

Cranial nerves are an integral part of the peripheral nervous system, playing a crucial role in transmitting afferent and efferent nerve impulses, particularly in the head and neck area. Unlike spinal nerves, cranial nerves have distinct functional nuclei in the brainstem, grouped into sensory (posterior and lateral) and motor (anterior) nuclei. The optic nerve is a purely afferent (sensory) nerve, responsible for transmitting visual information from rod and cone receptors in the retina to the lateral geniculate nucleus (LGN) and superior colliculus (SC) in the thalamus. The optic nerve's innervation pathway begins with retinal ganglion cells, which form nerve fibers, pass through the optic canal, and then cross at the optic chiasm. Disruption of this pathway can lead to various clinical manifestations, such as vision loss or visual field impairment, which will be discussed further. Therefore, a thorough understanding of the anatomy and function of the optic nerve is crucial for the diagnosis and treatment of neuro-ophthalmological conditions.

Abstract

Influenza is an acute contagious respiratory infection that remains a major global health concern due to its high transmissibility and ability to undergo genetic variations through antigenic drift and shift. This review aims to provide a comprehensive understanding of the definition, epidemiology, pathophysiology, clinical manifestations, diagnostic methods, management, complications, and preventive strategies of influenza based on recent scientific evidence. A narrative review method was employed by analyzing publications from 2008 to 2025, sourced from PubMed, ScienceDirect, and Google Scholar, using keywords such as “influenza,” “respiratory infection,” “antiviral therapy,” and “influenza vaccination.” The findings show that influenza affects approximately one billion people globally each year, with 3–5 million severe cases and 290,000–650,000 respiratory deaths, particularly among vulnerable groups including children, the elderly, pregnant women, and individuals with chronic diseases. The infection is caused by influenza viruses type A, B, C, and D, with type A being the most associated with epidemics and pandemics. Diagnosis is primarily based on clinical assessment supported by RT-PCR as the gold standard, while neuraminidase inhibitors such as oseltamivir and zanamivir remain the mainstay of therapy when administered early. Annual vaccination remains the most effective preventive measure, complemented by non-pharmacological interventions such as hand hygiene, mask use, and respiratory etiquette. In conclusion, strengthening surveillance systems, improving vaccination coverage, and enhancing early diagnostic capacity are essential strategies to reduce the global burden of influenza and its complications.
