Study Notes

History & Physical Examination

Symptoms associated with endocrine disorders are frequently varied and non-specific
Endocrine disorders can affect many body systems
Except for the thyroid and testes, endocrine glands cannot be physically assessed

Anatomy Review

The main endocrine glands are the pituitary, thyroid, parathyroids, pancreas, adrenals and gonads - testes and ovaries.
The parathyroid glands and pancreas respond to metabolic signals
The thyroid, adrenals, and gonads are controlled by hormones released from the pituitary gland

Review of Systems

Patients should be asked about symptoms related to heat or cold intolerance, excessive sweating, thirst, hunger, and urination

General Survey & Vital Signs

Evaluate the patient for signs of restlessness and agitation, which may suggest hyperthyroidism
Evaluate the patient for lethargy and slowness, which may be characteristic of hypothyroidism
Check for central adiposity, which can be associated with Cushing’s syndrome, metabolic syndrome, and growth hormone deficiency
Assess the pulse for rate, rhythm, and volume, as tachycardia and atrial fibrillation can be seen with thyrotoxicosis
Record the blood pressure - hypertension can be a feature of pheochromocytoma and primary hyperaldosteronism
Check for orthostatic hypotension when assessing adrenal insufficiency

Skin, Nails, and Hair

Examine the skin for abnormal pallor, plethora, abnormal pigmentation, and thinning and fragility
Evaluate for the quality and quantity of body hair
Inspect for hirsutism in females, which may be related to polycystic ovary syndrome (PCOS)
Assess for thinning of the lateral eyebrows, which can be a symptom of hypothyroidism

HEENT Examination

Examine the eyes for external inflammation/edema, proptosis, diplopia, and visual function in thyroid patients - these symptoms may indicate Graves’ disease or hyperthyroidism
Check for periorbital edema and lid lag, which are often seen in hypothyroidism
Evaluate visual fields and acuities in patients with suspected pituitary tumors, as compression of the optic chiasm can cause bitemporal hemianopia
Inspect the oral mucosa for hyperpigmentation

Neck Examination

Examine the posterior neck for acanthosis nigricans, which can be associated with insulin resistance, and a dorsocervical fat pad (buffalo hump) which can indicate Cushing syndrome
Assess the neck for thyromegaly and goiter, recording size, surface, and consistency if present
Auscultate the thyroid for a bruit if Graves’ disease is suspected

Chest & Abdomen Examination

Look for gynecomastia in men, which can be seen in Klinefelter syndrome
Check for galactorrhea, or milk production in men or non-breastfeeding women
Inspect the axillae for acanthosis nigricans, which is often associated with insulin resistance and loss of axillary hair, which can be a feature of Addison’s disease.
Inspect the abdomen for striae which can suggest Cushing’s syndrome.
Assess the abdomen for palpability of adrenal tumors
Remember that adrenal tumor palpation can be dangerous if pheochromocytoma is suspected because it may trigger a hypertensive crisis

Genitalia Examination

Examine the external genitalia, and perform Tanner staging in adolescents.
Assess testicular consistency and volume

Extremities Examination

Examine the hands for excessive sweating, soft tissue overgrowth (acromegaly), skin crease pigmentation (Addison’s disease), wasting of the thenar muscles due to carpal tunnel syndrome (hypothyroidism, acromegaly), and acropachy (Graves’ disease)
Inspect the legs for pretibial myxedema (Graves’ disease), proximal muscle wasting and weakness (Cushing’s syndrome and hyperthyroidism), and ulceration (diabetes)

Endocrine System

Examining and diagnosing endocrine disorders can be difficult.
Symptoms are often diverse and nonspecific.
Endocrine disorders can affect numerous body systems.
Except for the thyroid and testicles, endocrine glands cannot be physically assessed.

Anatomy Review

The main endocrine glands include the pituitary, thyroid, parathyroids, pancreas, adrenals, and gonads (testes and ovaries).
The parathyroid glands and pancreas respond directly to metabolic cues.
The thyroid, adrenals, and gonads are primarily regulated by hormones released from the pituitary gland.

Endocrine ROS

Important questions to ask include:
- Heat or cold intolerance
- Excessive sweating
- Excessive thirst
- Excessive hunger
- Excessive urine output
General, skin, neck, cardiovascular, gastrointestinal, musculoskeletal, psychiatric, and neurologic system reviews are important to assess for other signs and symptoms.

General Survey & Vital Signs

Observe for signs associated with hyperthyroidism (restlessness, agitation) or hypothyroidism (slowness, lethargy).
Evaluate for central adiposity (Cushing’s syndrome, metabolic syndrome, growth hormone deficiency) in obese patients.
Assess pulse rate, rhythm, and volume, noting tachycardia and atrial fibrillation as potential indicators of thyrotoxicosis.
Record blood pressure. Hypertension is a hallmark of various endocrine conditions (pheochromocytoma, primary hyperaldosteronism).
Measure lying and standing blood pressures to assess for postural hypotension, suggestive of adrenal insufficiency.

Skin, Nails & Hair

Examine the skin surface for:
- Abnormal pallor (hypopituitarism)
- Plethora (Cushing's or carcinoid syndrome)
- Abnormal pigmentation (Addison's disease)
- Skin thinning and fragility (Cushing syndrome)
Assess hair quality and quantity, noting hirsutism (polycystic ovary syndrome (PCOS)) in women with menstrual disturbances, evident on the face, chest, and abdomen.
Note thinning of lateral eyebrows (hypothyroidism).

HEENT Examination

Examine the eyes in all thyroid patients for:
- External inflammation/edema
- Proptosis
- Diplopia
- Visual function (hyperthyroidism/Graves disease)
Assess for periorbital edema and lid lag (hypothyroidism).
Evaluate visual acuity and fields in patients with suspected pituitary tumors (bi-temporal hemianopia due to optic chiasm compression).
Inspect the oral mucosa for hyperpigmentation.

Neck Examination

Inspect the posterior neck for acanthosis nigricans (insulin resistance) and a dorsocervical fat pad (buffalo hump – Cushing syndrome).
Examine the neck for thyromegaly and goiter.
If present, record its size, surface features, and consistency.
Auscultate for a thyroid bruit if Graves disease is suspected.

Chest & Abdomen Examination

Look for gynecomastia in men (common in Klinefelter syndrome - 47XXY) and galactorrhea (milk production in men or non-breastfeeding women).
Inspect the axillae for acanthosis nigricans (insulin resistance) or axillary hair loss (Addison's disease).
Inspect the abdomen for striae (Cushing syndrome).
Adrenal tumors may be palpable in the abdomen.
Exercise caution if pheochromocytoma is suspected, as aggressive examination may potentially trigger a hypertensive episode.

Genitalia Examination

Examine the external genitalia.
Use Tanner staging for pubertal development in adolescents.
Record testicular consistency and volume

Extremities Examination

Examine the hands for:
- Excessive sweating
- Soft tissue overgrowth (acromegaly)
- Skin crease pigmentation (Addison's disease)
- Wasting of the thenar muscles (carpal tunnel syndrome – hypothyroidism, acromegaly)
- Acropachy (Graves disease)
Inspect the legs for:
- Pretibial myxedema (Graves disease)
- Proximal muscle wasting and weakness (Cushing's syndrome and hyperthyroidism)
- Ulceration (Diabetes)

Endocrine System

Diagnosing endocrine issues can be difficult due to varied and non-specific symptoms
Endocrine glands affect multiple bodily systems
Endocrine glands cannot be physically assessed except for the thyroid and testicles

Anatomy Review

Main endocrine glands include pituitary, thyroid, parathyroid, pancreas, adrenal glands, and gonads (testicles and ovaries)
Parathyroid glands and pancreas directly respond to metabolic signals
Thyroid, adrenal glands, and gonads are primarily controlled by hormones released from the pituitary gland

Endocrine ROS

Heat or Cold Intolerance: Can indicate thyroid dysfunction
Excessive Sweating: Can suggest hyperthyroidism or other endocrine issues
Excessive Thirst: Can be a sign of diabetes or other disorders affecting fluid balance
Excessive Hunger: Can be associated with diabetes, but also other conditions
Excessive Urine Output: May indicate diabetes, diabetes insipidus, or other renal issues
Other Systems: Review general, skin, neck, cardiovascular, GI, MSK, Psych, and Neurologic systems for potential clues
