Hypertension III: Clinical Manifestations and Diagnostic Studies

685
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Sympathetic Pathways: Collateral Ganglia and Adrenal Medulla

3.1K
The sympathetic pathways of the collateral ganglia and adrenal medulla serve unique but interconnected roles in the sympathetic response.
Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Chronic Kidney Disease II: Clinical Manifestations

801
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

3.6K
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...

Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

68.6K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Summary

Subclinical Cushing's syndrome involves subtle cortisol excess, making diagnosis difficult. Treatment involves laparoscopic adrenalectomy and perioperative steroids for patients with adrenal incidentalomas.

Area of Science:

  • Endocrinology
  • Internal Medicine

Background:

  • Subclinical Cushing's syndrome (SCS) presents with subtle autonomous cortisol hypersecretion, lacking overt clinical signs.
  • Diagnosis of SCS is complex due to its non-specific presentation.

Purpose of the Study:

  • To outline the diagnostic challenges and treatment strategies for subclinical Cushing's syndrome.

Main Methods:

  • Utilizing the 1 mg overnight dexamethasone suppression test.
  • Assessing serum ACTH levels.
  • Measuring 24-hour urinary free cortisol levels.

Main Results:

  • The combination of these tests aids in diagnosing SCS.
  • Laparoscopic adrenalectomy is the preferred surgical intervention.

  • Perioperative steroid management is crucial for patients with adrenal incidentalomas and SCS to prevent hypocortisolism.

    • Conclusions:

    • Accurate diagnosis of SCS relies on a multi-faceted testing approach.
    • Surgical management via laparoscopic adrenalectomy is effective for SCS.
    • Perioperative care is essential for managing adrenal insufficiency post-surgery in specific patient cohorts.
