Hyperthyroidism II: Pathophysiology01:27

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

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...
Hypothyroidism II: Pathophysiology01:23

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
Endocrine Signaling01:45

Endocrine Signaling

Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Introduction to Language of Pathophysiology ll

This lesson explores key terms that describe how diseases progress, their outcomes, and their distribution in populations.Diagnostic tests identify diseases and monitor treatment. These include blood and urine tests, biopsies, imaging (X-ray, MRI), and detection of infectious agents.Remission is a reduction or disappearance of symptoms.Exacerbation refers to the worsening of symptoms, such as increased wheezing during an asthma attack.A precipitating factor triggers an acute episode, while a...

Summary

Multiple Endocrine Neoplasia type 1 (MEN1) diagnosis in young patients is challenging. Cutaneous collagenomas can aid in early MEN1 diagnosis and management, as seen in this adolescent case.

Area of Science:

  • Endocrinology
  • Genetics
  • Dermatology

Background:

  • Multiple Endocrine Neoplasia type 1 (MEN1) diagnosis presents challenges, particularly in pediatric and young adult populations, due to variable clinical presentations.
  • Phenotypic heterogeneity within families can further complicate early and accurate diagnosis.

Observation:

  • An adolescent female presented with numerous cutaneous collagenomas (>70 lesions).
  • Histological examination confirmed the diagnosis of collagenomas.

Findings:

  • Genetic sequencing of the MEN1 gene identified a novel nonsense mutation (Y222X).
  • Endocrine evaluation revealed asymptomatic primary hyperparathyroidism, confirmed as parathyroid hyperplasia during surgery.
  • The patient was diagnosed with MEN1 following the identification of collagenomas and subsequent endocrine findings.

Implications:

  • Cutaneous manifestations, such as collagenomas, can serve as crucial early indicators for MEN1 diagnosis.
  • Prompt recognition of dermatological signs can facilitate timely endocrine assessment and management, improving patient outcomes.
  • This case highlights the importance of integrating dermatological findings into the diagnostic pathway for MEN1 in younger individuals.
