1. Introduction Eating disorders represent a group of severe psychiatric conditions characterized by persistent disturbances in eating behaviors and associated distressing thoughts and emotions. These disorders are associated with significant morbidity and mortality, impacting physical health, psychological well-being, and overall quality of life. The core diagnostic categories include anorexia nervosa (AN), bulimia nervosa (BN), and … Read more

1. Introduction Adolescent health encompasses the physical, psychological, and social well-being of individuals during the transitional period from childhood to adulthood, typically spanning ages 10 to 19 years. A central biological process underpinning this stage is puberty, a complex sequence of neuroendocrine events leading to sexual maturation and the attainment of reproductive capability. Disorders of … Read more

1. Introduction The discipline of pediatrics encompasses the medical care of individuals from birth through adolescence, a period characterized by profound and dynamic physiological change. Pediatric medicine and pharmacology are not merely scaled-down versions of adult practice but are founded on distinct principles that account for the continuum of human development. The management of pediatric … Read more

1. Introduction Neonatal care, particularly for the infant born prematurely, represents a specialized domain of medicine and pharmacology that addresses a uniquely vulnerable patient population. This field integrates principles of developmental biology, pathophysiology, and pharmacokinetics to manage conditions arising from incomplete organ system maturation. The care of preterm infants, defined as those born before 37 … Read more

1. Introduction Congenital anomalies represent a significant domain within medical and pharmaceutical sciences, with craniofacial malformations such as cleft lip and palate (CL/P) constituting some of the most prevalent structural birth defects. A cleft palate is characterized by an incomplete fusion of the palatal shelves during embryogenesis, resulting in a communication between the oral and … Read more

1. Introduction The study of genetic disorders represents a cornerstone of modern medical and pharmaceutical sciences, providing fundamental insights into the etiology of disease and the biological basis for inter-individual variability in drug response. Down syndrome, resulting from trisomy of chromosome 21, serves as the most prevalent autosomal chromosomal aneuploidy compatible with postnatal life. Its … Read more

1. Introduction Autism spectrum disorder (ASD) represents a heterogeneous group of complex neurodevelopmental conditions characterized by persistent deficits in social communication and social interaction, alongside the presence of restricted, repetitive patterns of behavior, interests, or activities. The diagnostic conceptualization has evolved from earlier, narrowly defined categories to a single, dimensional spectrum disorder as outlined in … Read more

1. Introduction Amyotrophic lateral sclerosis (ALS) represents a progressive, fatal neurodegenerative disorder characterized by the selective degeneration of both upper motor neurons (UMNs) in the cerebral cortex and lower motor neurons (LMNs) in the brainstem and spinal cord. This dual involvement leads to a clinical syndrome of muscle weakness, atrophy, spasticity, and ultimately paralysis, with … Read more

1. Introduction Multiple sclerosis is a chronic, immune-mediated disorder of the central nervous system characterized by inflammation, demyelination, gliosis, and subsequent neurodegeneration. The condition represents a leading cause of non-traumatic neurological disability in young adults, with a complex pathophysiology involving an interplay between genetic susceptibility and environmental triggers. The clinical hallmark is neurological dysfunction disseminated … Read more

1. Introduction Parkinson’s disease represents a progressive neurodegenerative disorder primarily characterized by the loss of dopaminergic neurons within the substantia nigra pars compacta. This neuronal degeneration leads to a profound depletion of striatal dopamine, resulting in the cardinal motor features of bradykinesia, resting tremor, rigidity, and postural instability. As the second most common neurodegenerative disease … Read more
