Study Notes

Endocrine System

Hormones are chemical messengers that regulate cell communication, metabolism, growth, and development.
Paracrine hormones target nearby cells, while autocrine hormones target the cells that secreted them.
Major hormone types include peptides (amino acid chains), steroids (derived from lipids, often affecting reproduction), and amines (derived from amino acids).
Hormone receptors are specific to each hormone (only cells with the corresponding receptor can respond).
Hormone receptors can increase (up-regulation) or reduce (down-regulation) in number, thereby affecting hormone sensitivity.
Hormones are degraded by enzymes at receptor sites, cellular uptake, or liver excretion.

Hypothalamic-Pituitary System

The pituitary gland has two regions: the posterior pituitary and the anterior pituitary.
The posterior pituitary stores and releases hormones made in the hypothalamus.
The anterior pituitary makes and releases hormones affecting other glands.
Hormones of the hypothalamic-pituitary axis regulate important functions: growth, reproduction, and metabolism.

Diseases of the Posterior Pituitary

Diabetes insipidus (DI) is a condition characterized by insufficient ADH (antidiuretic hormone) secretion; leading to excessive urination and thirst.
Syndrome of inappropriate antidiuretic hormone (SIADH) secretion involves excessive ADH production, leading to fluid retention.
ADH (also called vasopressin) controls blood osmolarity.

Diseases of the Anterior Pituitary

Hypopituitarism is a condition where the anterior pituitary doesn't produce enough hormones, resulting in multiple hormone deficiencies.
Hyperpituitarism is a condition of excess pituitary hormone production, often due to tumors.
Specific hormones produced by the anterior pituitary like thyroid-stimulating hormone (TSH), Adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), and growth hormone (GH). Excess or inadequacy of these hormones can cause diseases.

Thyroid Gland Disorders

The thyroid gland produces hormones that regulate metabolism, energy, and nervous system function.
Hypothyroidism is a condition where the thyroid gland doesn't produce enough thyroid hormones, resulting in various symptoms, including fatigue, weight gain, and cold intolerance.
Hyperthyroidism is a condition where the thyroid gland produces excessive thyroid hormones, resulting in symptoms like weight loss, anxiety, and heat intolerance.

Adrenal Gland Disorders

Adrenal glands produce hormones involved in stress response, blood pressure regulation, and electrolyte balance.
Addison's disease, characterized by insufficient adrenal hormone production, causes symptoms including fatigue, low blood pressure, and electrolyte imbalance.
Cushing's syndrome is associated with excessive cortisol production, manifesting as weight gain, high blood sugar, and muscle weakness.

Renal System

The kidneys regulate water and electrolyte balance and filter waste products from the blood.
Urinary tract obstructions can lead to fluid backup, infection, and damage to the kidneys.
Renal calculi (kidney stones) are hard deposits in the kidney that can cause pain and blockage.
Renal failure is a condition where the kidneys lose their ability to filter waste, often associated with complications and requiring dialysis or transplantation. -Prerenal is caused by decreased blood flow to the kidneys
- Intrarenal failure is caused by intrinsic kidney pathology -Postrenal failure is caused by downstream obstruction of the urinary tract.

Urinary Tract Infections

Urinary tract infections (UTIs) are infections in the urinary system, usually caused by bacteria like E. coli.
UTIs can affect the bladder (cystitis), ureters, kidneys (pyelonephritis).
Risk factors include anatomical differences, sexual activity, and instrumentation.

Benign Prostate Hyperplasia (BPH)

Enlarged prostate gland in older men, associated with urinary symptoms like difficulty urinating and frequent urination.
Usually not cancerous.

Neurogenic Bladder

Damage to nerve pathways that control bladder function results in incontinence or retention difficulties.

Renal Tumors

Benign renal tumors are less common than malignant ones and are often asymptomatic.
Common malignant tumors include renal cell carcinoma; characterized by specific cell types, risk factors, and clinical presentation.

Bladder Tumors

Bladder tumors are often related to exposure to environmental carcinogens, particularly smoking.
Common types include transitional cell carcinomas; often associated with hematuria and diverse clinical presentations depending on stage.

External Genitalia Infections

Sexually transmitted infections (STIs) can manifest as various external genital infections, with symptoms like pain, discharge, or ulcerations.

Male Reproductive Disorders

Cryptorchidism is the failure of one or both testes to descend into the scrotum.
Testicular torsion is a twisting of the spermatic cord, causing severe pain and potential testicular damage.
Orchitis is inflammation of the testis.
Epididymitis is inflammation of the epididymis.
Varicocele is a varicose vein in the spermatic cord, disrupting blood flow and often causing infertility.
Hydrocele describes a fluid-filled sac in the scrotum, typically a result of developmental issues.
Spermatocele is a cyst containing sperm in the epididymis.

Reproductive System Disorders in Women

Polycystic ovary syndrome (PCOS) is a hormonal disorder, often diagnosed in young women, with various clinical manifestations, particularly menstrual irregularities and potential fertility issues.
Dysfunctional uterine bleeding (DUB) is abnormal uterine bleeding not associated with ovulation.
Primary amenorrhea is the absence of menstruation by age 15 or beyond normal puberty.
Secondary amenorrhea is the absence of menstruation in women who previously menstruated regularly.
Pelvic relaxation disorders like cystocele, rectocele and uterine prolapse lead to displacement of pelvic organs, causing symptomatic issues such as urinary or fecal incontinence.

Benign Breast Disorders

Galactorrhea is the spontaneous milky or yellowish discharge from the nipple, unrelated to pregnancy or breastfeeding.
Fibrocystic changes (FCC) – is a common benign condition involving cysts and fibrous tissue within the breast tissue; often associated with pain and tenderness.

Breast Tumors

Benign breast tumors such as fibroadenomas are more common.
Malignant breast tumors like adenocarcinomas are potentially life-threatening; if diagnosed early, aggressive treatment can improve outcomes.

Inflammatory or Vascular Disorders of the Skin

Allergic contact dermatitis results from exposure to allergens causing an immune response that triggers skin inflammation.
Stasis dermatitis results from venous insufficiency in the lower extremities leading to chronic inflammation and skin changes.
Scleroderma is an autoimmune disease characterized by widespread fibrosis affecting the skin and other organs.
Psoriasis is a chronic inflammatory skin disorder, presenting with red scaly patches.
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease and also presents with skin manifestations such as rashes.

Burns

Burns have various classifications (first-degree, second-degree, etc.) based on the depth of skin damage, influencing treatment approaches.
Burns can result in significant systemic complications, including fluid loss and potentially organ failure, impacting the need for intensive treatment and care.

Infections of the Skin

Acne vulgaris – infection or blockage of sebaceous glands
Furuncles/cellulitis – infection of skin hair follicles→ can become widespread
Impetigo is contagious, occurs most often in children.
Bacterial skin infections can cause redness, swelling, and pain in the infected area.
Viral skin infections can include herpes zoster (shingles), chickenpox, wart, etc..
Fungal skin infections are characterized by various types of tinea(e.g., tinea pedis, tinea corporis) affecting different parts of the body.
Parasites like scabies or lice cause skin irritation and itching.

Frost bite – is a skin injury caused by freezing of the skin and underlying tissues -SBRK – common benign skin growth in older individuals, characterized by raised, waxy or scaly patches on the skin. -Actinic/solar keratos- rough scaly patches are caused by sun damage

Skin Cancer

Skin cancer manifests in various ways, ranging from melanomas (the most serious type) and non-melanomas (basal cell and squamous cell carcinomas).
