Summary
A boy with autism and ADHD developed severe feeding issues due to non-malignant germ-cell tumors affecting his pituitary gland. Treatment involved radiotherapy and hormone replacement.
Area of Science:
- Pediatric Endocrinology
- Neuro-oncology
- Developmental Neuroscience
Background:
- Autistic Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) can present with feeding and behavioral issues.
- Disinhibited behavior and severe food refusal in adolescents may be misattributed to psychogenic causes.
- Eating disorder facilities may not always identify underlying organic pathologies.
Observation:
- A 9-year-old boy with diagnosed ASD and ADHD exhibited feeding and behavioral problems.
- By age 11, he developed disinhibition and severe oral food refusal, leading to inpatient eating disorder treatment.
- Persistent vomiting and minimal intake necessitated further medical investigation.
Findings:
- Hypovolemic hypernatremia indicated severe dehydration.
- MRI revealed multiple tumor masses with suprasellar and pituitary involvement.
- Histology confirmed primary, non-malignant germ-cell tumors.
Implications:
- This case highlights the importance of considering organic causes, such as brain tumors, in patients with severe feeding refusal and behavioral changes, even with prior neurodevelopmental diagnoses.
- Early identification and treatment of pituitary tumors are crucial to prevent severe metabolic derangements and long-term complications.
- Multidisciplinary management involving neuro-oncology, endocrinology, and behavioral specialists is essential for optimal outcomes in complex pediatric cases.

Adrenal Gland Disorders
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
Major Hormones and Their Functions
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.

Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
