Adrenal Gland Disorders01:27

Adrenal Gland Disorders

3.7K
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 I: Introduction01:26

Cushing Syndrome I: Introduction

36
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...

Cushing Syndrome II: Pathophysiology

24
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...

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

6.6K
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.4K
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....

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

359
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...

Area of Science:

  • Endocrinology
  • Genetics
  • Pediatrics

Background:

  • Congenital adrenal hyperplasia (CAH) is a group of rare genetic disorders affecting the adrenal glands.
  • Enzyme deficiencies in the steroidogenic pathway lead to impaired cortisol synthesis and androgen excess.
  • Female genotypes with CAH may exhibit virilization due to elevated androgens.

Observation:

  • This report details a case of classic congenital adrenal hyperplasia, specifically the simple virilizing type.
  • The patient presented with symptoms later in childhood, deviating from the typical early infant presentation.
  • The presentation involved virilization, a characteristic feature of androgen excess in CAH.

Findings:

  • The case illustrates that classic CAH, even the simple virilizing form, can manifest later than typically observed.
  • Diagnostic evaluation confirmed the specific enzyme deficiency responsible for the condition.
  • The patient's delayed presentation underscores the heterogeneity in the clinical onset of CAH.

Implications:

  • This case emphasizes the importance of considering CAH in children presenting with virilization, regardless of age.
  • Management strategies for CAH, including hormone replacement and potential surgical interventions, are crucial.
  • Understanding the varied timelines of CAH presentation aids in timely diagnosis and appropriate patient care.
