Main function of endocrine system
Maintain body homeostasis
Endocrine organs?
- Pituitary
- Parathyroid
- Hypothalamus
- Thyroid
- Adrenals
- Pancreas
- Ovaries/Tested
- Adipose
Endocrine pathophysiology
Primary, Secondary, and Tertiary
Affects..?
Primary- glands
Secondary- pituitary gland
(Can be iatrogenic)
Tertiary- hypothalamus
Endocrine pathology affecting pituitary gland
Diabetes Insipidus
SIADH: syndrome of inappropriate secretion of antidiuretic hormone
Acromegaly
Types of diabetes insipidus
CDI- central
NDI- nephrogenic
Clinical s/s of DI (diabetes insipidus)
Polyuria Nocturia Polydipsia Dehydration Decreased urine specific gravity Increased serum sodium
CDI: central diabetes insipidus
Idiopathic or primary:
Autoimmune
Secondary: Pituitary trauma (neurosurgery/head trauma) Infections (meningitis, encephalitis) Tumor Anorexia Vascular lesions
NDI: nephrogenic diabetes insipidus
Medications:
Lithium (20% chronic users)
Demeclocycline, amphotericin, colchine
Alcohol imbalances:
Hyperkalemia / Hypokalemia
Renal disease:
SLE, Sarcoidosis, Multiple myeloma, polynephritis
Risk factors of SIADH
Pituitary damage due to infection, trauma or neoplasm
Secretion of vasopressin-like substances
Thoracic pressure changes from compression of pulmonary or cardiac pressure receptors or both
Clinical s/s of SIADH
HA, confusion, lethargy (most significant early indicators)
Decreased urine output
Weight gain without visible edema
Seizure
Muscle cramping
Vomiting, diarrhea
Increased urine specific gravity (> 1.03)
Decreased serum sodium (< 135 mEq/dL; caused by dilution of serum from water)
Acromegaly in children
GH stimulates growth of long bones
Gigantism
Clinical presentation of acromegaly
Degenerative arthropathy Hand stiffness Carpal tunnel syndrome Proximal myopathy and fibromyalgia Back pain
S/S Acromegaly
Bony enlargement (face, jaw, hands, feet) Amenorrhea DM Profuse sweating (diaphoresis) HTN CTS (carpal tunnel syndrome) Hand pain stiffness Back pain (thoracic and/or lumbar) Proximal myopathy Poor exercise tolerance Fibromyalgia
S/S adrenal insufficiency
Dark pigmentation of skin, esp mouth and scars (occurs only with primary disease; Addison’s disease) Hypotension Progressive fatigue Hyperkalemia (generalized weakness and muscle flaccidity) Anorexia and weight loss Nausea and vomiting Arthralgias, myalgias (secondary only) Tendon calcification Hypoglycemia
Risk factors for thyroid disease
Genetics
> 50 years old
Women > Men
Clinical s/s goiter
Increased neck size Pressure on adjacent tissue (ie Trachea, esophagus) Difficulty breathing Dysphagia Hoarseness
Clinical s/s thyroiditis
Painless thyroid enlargement
Dysphagia, “tight” sensation when swallowing, or choking
Anterior neck, shoulder or rib cage pain without biomechanical changes
Gland sometimes easily palpable over anterior neck (warm, tender, swollen)
Fatigue, weight gain, dry hair and skin, constipation (later symptoms assoc w/ hypothyroidism)
Hypothyroidism
Hair? Eyes? Face? Thyroid gland? Heart? GI? Temp? MSK? Edema?
Loss of hair
Coarse, brittle hair
Periorbital edema Puffy face Normal or small thyroid Heart failure- Bradycardia Constipation Cold intolerance Muscle weakness Edema of extremities
Hyperthyroidism
Hair? Eyes? Thyroid gland? Heart? GI? Temp? MSK? Edema?
Thin hair
Exophthalmos
Enlarged thyroid: diffuse (warm) , nodular, solitary “toxic” nodule
Heart failure- Tachycardia Weight loss, diarrhea Warm skin, sweaty palms Hyperreflexia Pretibial edema
6 major functions of the liver
- Produce albumin and other plasma proteins
- Bile production
- Conversion and excretion of bilirubin
- Produce clotting factors
- Store vitamins
- Immune system for gut
Liver and gallbladder primary pain pattern
Mid-epigastrium
Or
Right upper quadrant of the abdomen
Liver and gallbladder secondary referral patterns
Liver:
T7-T10
Right shoulder
Gallbladder:
Right shoulder
Right interscapular (T4/T5 to T8)
Right subscapular area
Any pain in the ____ should warrant inquiry ruling out visceral sources.
Mid thoracic spine
T4/T5-T8 gallbladder
T7-T10 liver
The patient’s main complaint may be of pain in the shoulder, lower lumbar and sacral spine or anterior groin.
S/S of hepatic disease
- GI- nausea, vomiting, diarrhea, constipation, heartburn
- Edema/Ascites
- Dark urine
- Light or clay colored stools
- Right upper quadrant abdominal pain
- Skin changes: jaundice, bruising, spider angina, palmar erythema
- Neuro involvement: confusion, sleep disturbance, muscle tremors, hyper-reflex, asterixis
- MSK pain
- Hepatic osteodystrophy
Portal hypertension
Increased venous blood pressure in portal vein
Pressure > 6 mmHg
Most common in cirrhosis
Increased pressure-> Reversal of blood back to stomach, esophagus, umbilicus, rectum -> vessels continue to enlarge (varices)
Cirrhosis
Progressive loss of normal tissue replaced with fibroids and nodular regeneration
Cirrhosis s/s
Fatigue Weight loss Jaundice Coagulopathies Loss of ability to metabolize drugs Hypoalbuminemia has
Ascites
Pathological accumulation of fluid within peritoneal cavity
Volume > 1.5L can be detected by physical exam
Grade I: no symptoms, dx by US (min: 100 mL fluid)
Grade II: 1000+ mL fluid, increased abdominal girth, weight gain
Grade III: diffuse abdominal pressure, dyspnea (if diaphragm elevated by fluid), pain uncommon
Infectious (spontaneous bacterial peritonitis): new abdominal discomfort and fever
