Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

379
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Parkinson's Disease: Overview

820
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

2.0K
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...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

938
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...

Hypertension III: Clinical Manifestations and Diagnostic Studies

78
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...

Area of Science:

  • Endocrinology
  • Reproductive Health

Background:

  • Hyperprolactinemia, elevated serum prolactin, commonly affects women, presenting with symptoms like galactorrhea, oligomenorrhea, amenorrhea, or infertility.
  • While often caused by identifiable factors, rare instances of idiopathic hyperprolactinemia, resolving without intervention, have been documented.

Observation:

  • A 39-year-old woman experienced amenorrhea for four months post-Implanon removal and persistent galactorrhea for four years, even after breastfeeding cessation.
  • Initial investigations, including imaging, were conducted to identify the cause of her symptoms.

Findings:

  • Despite extensive workup ruling out common physiological and pathological causes, the hyperprolactinemia was deemed idiopathic.
  • The patient's condition presented diagnostic challenges in primary care due to the unclear etiology.

Implications:

  • This case underscores the importance of considering idiopathic hyperprolactinemia, even when symptoms are persistent.
  • Successful management with adequate treatment led to the resolution of menstrual irregularities and galactorrhea, demonstrating treatment efficacy.
