I have everything I need. Now let me write clean, exam-ready notes.Here are your full exam notes, covering everything from both files:

🦋 THYROID & PARATHYROID - EXAM NOTES

1. GRAVES' DISEASE (Diffuse Toxic Goiter)

What is it?

A systemic autoimmune disease where the body makes anti-TSH receptor antibodies that stimulate the thyroid, causing thyrotoxicosis + extrathyroidal effects (ophthalmopathy, dermopathy).

Etiology

Genetics, psychosocial stress, environment
Infections/inflammations, traumas, nasopharyngeal diseases

Pathogenesis

Anti-TSH antibodies → stimulate thyroid → activate primary metabolism → dystrophic changes

Clinical Features

Catabolic syndrome:

Progressive weight loss (10-15 kg) despite HIGH appetite
Fatigue, hot skin, feeling of heat (never feels cold)
High nighttime body temperature, diffuse sweating

Nervous system:

Aggressiveness, irregular movements, labile psyche
Fine tremor, osteopenic syndrome (hair loss, damaged nails)

Cardiovascular ("Thyrotoxic Heart"):

Permanent tachycardia
Extrasystoles
Heart rate doesn't change with position
Systolic BP HIGH, diastolic BP LOW
(Reversible thyrotoxic cardiomyopathy)

Other:

Menstrual cycle disorder, erectile dysfunction
Diarrhea, abdominal pain, vomiting
Pretibial myxedema
Skin: soft, hot, wet, hyperaemic; feet pigmented

Graves' Ophthalmopathy - 6 Classes

Class	Features
1	Spasm of upper eyelids
2	Periorbital edema + chemosis
3	Proptosis (exophthalmos)
4	Extraocular muscle involvement
5	Corneal involvement
6	Loss of vision (optic nerve)

Severity of Thyrotoxicosis

	Mild	Moderate	Severe
Weight loss	<10%	10-20%	>20% (cachexia)
Heart rate	<100/min	100-120/min	>120/min
BP	Normal	Systolic 130-150	Systolic 150-160, diastolic very low
Ophthalmopathy	Absent	Significant	Marked
Work capacity	Retained	Decreased	Completely lost

⚠️ Any form with ciliary arrhythmia, heart failure, psychosis, or hepatitis = classified as SEVERE

Diagnosis

TSH ↓, T3/T4 ↑
Endocrine ophthalmopathy
Diffuse thyroid enlargement
Diffuse uptake on Tc scintigraphy
Anti-rTSH antibodies positive
Hypercholesterolemia, hyperglycemia

Treatment

Depends on: severity, gland size, age, co-morbidities

Method	Indications	Outcome
Conservative	First-line: anti-thyroid drugs + β-blockers	-
Surgery	Huge gland, compression, pregnancy/lactation, arrhythmia, refractory goiter	→ Hypothyroidism
Radioiodine (I-131)	No anti-thyroid drugs before	→ Hypothyroidism

2. HYPOTHYROIDISM

What is it?

Clinical syndrome caused by deficiency of thyroid hormones.

Etiology

AIT (autoimmune thyroiditis - most common)
Iatrogenic: post-surgery, glucocorticosteroids, estrogens, androgens
Severe iodine deficiency
Thyroid destruction (infection, inflammation)
Thyroid dysgenesis (congenital defect)

Pathogenesis

Suppressed metabolism → ↓ glucose utilization → ↓ brain tissue → peripheral metabolism disorder → ↓ sensitivity to catecholamines → compensatory hyperprolactinemia, pituitary cysts/adenomas

Clinical Features - "MASKS" (tricky - looks like other diseases)

No specific symptoms. Severity of hormone deficiency does NOT match clinical severity.

Mask	Features
GIT	Constipation, gallstones, chronic hepatitis, hoarse voice, weight GAIN (low appetite), lung edema
Skin	Alopecia, hyperkeratosis, dry/pale/cold skin
Cardiological	Dyslipidemia, hydropericarditis, BRADYCARDIA, BP normal/low/high
Gynaecological	Ovarian dysfunction, uterine bleeding, amenorrhea/dysmenorrhea, infertility
Rheumatological	Polyarthritis, osteoarthrosis
Psychiatric	Depression, dementia, apathy, low IQ

Forms

Subclinical - TSH ↑, fT4 normal
Manifest - TSH ↑, fT4 ↓
Complicated (severe organ damage)

Diagnosis

TSH ↑ + fT4 ↓ = manifest hypothyroidism
TSH ↑ + fT4 normal = subclinical hypothyroidism
Thyroid ultrasound, FNA

Treatment

Levothyroxine (replacement therapy)
Dose: 1.7 mcg/kg; mean dose 0.125 mg/day; range 0.05-0.2 mg/day
Monitor TSH; check after 2-3 months
Elderly: start LOW (25-50 mcg/day x 5 weeks) due to coronary disease risk
Children need relatively HIGH doses
Subclinical hypothyroidism: treat ONLY during pregnancy

3. CRETINISM (Congenital Hypothyroidism)

Types

Athyrotic cretinism: congenital absence of thyroid gland
Goitrous cretinism: non-functioning goiter or failure to synthesize hormones

Clinical Features (classic picture)

Failure of skeletal growth and maturation
Severe intellectual disability/retardation
Puffy eyelids, flat/thick nose, thick lips, open mouth, large protruding tongue
Flat, harsh voice; hoarse cry (nearly diagnostic)
Short, thick neck
Dry, cool skin with non-pitting edema
Protuberant abdomen, umbilical hernia

⚠️ Without treatment: symptoms are exacerbated and become totally irreversible

4. AUTOIMMUNE THYROIDITIS (AIT)

What is it?

A heterogeneous group of autoimmune thyroid diseases where T-lymphocytes attack thyrocytes → normal tissue is destroyed and replaced by fibrotic/destructed follicular epithelium.

Pathogenesis

Genetic immune defect → T-lymphocyte aggression against thyrocytes → thyrocyte damage → normal tissue replaced by destroyed follicular epithelium

Types of Thyroiditis

Acute (suppurative) thyroiditis
Subacute (De Quervain's) thyroiditis
Silent (painless) thyroiditis
Chronic lymphocytic (Hashimoto's) thyroiditis
Fibrous (Riedel's) thyroiditis

5. SUBACUTE THYROIDITIS (De Quervain's / Granulomatous)

Cause

Viral infection - mumps virus, coxsackievirus, adenoviruses

Clinical Features

Fever, malaise
Neck soreness extending to jaw/ear
Symptoms of transient hyperthyroidism (NO ophthalmopathy)
Tachycardia, tremor, hyperreflexia
No local redness/heat/abscess
Triphasic course: Hyperthyroid → Hypothyroid → Euthyroid (recovery)
Permanent hypothyroidism or relapses are UNCOMMON

Phases & Labs

Phase	T3/T4	RAIU	TSH
I - Hyperthyroid	↑	↓	↓
II - Euthyroid	Normal	↓	↓
III - Hypothyroid	↓	Normal/↑	↑
IV - Recovery (Euthyroid)	Normal	Normal	Normal

Treatment

Prednisolone 30-40 mg/day x 7-10 days, then taper by 5-10 mg every 10 days
Levothyroxine 0.1-0.15 mg/day during hypothyroid phase

6. HASHIMOTO'S THYROIDITIS (Chronic Lymphocytic)

Most common cause of:

Hypothyroidism
Goiter (especially in children and young adults)
"Idiopathic myxedema"

Clinical Features

Patient presents with painless goiter, euthyroid or mildly hypothyroid
Patient may be unaware of goiter unless it enlarges greatly
Older patients: severe hypothyroidism + small, firm, atrophic gland

Diagnosis

Anti-TPO antibodies strongly positive (↑↑↑)
Ultrasound
Subclinical or manifest hypothyroidism

Treatment

No special treatment needed until AIT causes hypothyroidism → then levothyroxine

7. ENDEMIC GOITER

What is it?

Goiter present in >5% of general population OR >10% of school-age children in a defined area
Caused by iodine deficiency → TSH-driven thyroid hypertrophy

Pathogenesis

↓ Iodine → ↓ thyroid hormone production → negative feedback removed → ↑ TSH → diffuse thyroid hypertrophy

Clinical Features

Hypothyroidism (due to low thyroid hormones)
Goiter may cause dysphagia or airway obstruction
Nodular goiters can progress to thyroid follicular carcinoma

Diagnosis

TSH ↑, no antibodies
Ultrasound: enlarged thyroid

Treatment

Iodine therapy (primary)
Levothyroxine if hypothyroid
Surgery if massive enlargement

8. SPORADIC (NON-TOXIC) GOITER

What is it?

Benign thyroid enlargement in a euthyroid person living in an iodine-sufficient area. Can be diffuse, uninodular, or multinodular.

Etiology

Autoimmune, genetic, and extrinsic (environmental) factors - incompletely understood

Clinical Features / Treatment goals

May have features of hypo- or hyperthyroidism
Treatment aims: relieve compressive symptoms, prevent enlargement, treat dysfunction

9. HYPERPARATHYROIDISM (HPT)

What is it?

Excess PTH production → hypercalcemia syndrome

Etiology / Pathogenesis

Parathyroid adenoma (most common), multiple adenomas (rare), parathyroid cancer (rare)
PTH ↑ → phosphate excreted by kidneys ↑ (plasma phosphate ↓) → 1,25-(OH)₂-D₃ ↑ → calcium absorbed from intestine ↑

Types

Primary: parathyroid adenoma or hyperplasia → hypercalcemia
Secondary: long-term hyperstimulation (e.g., chronic renal failure) → PTH ↑ but NO hypercalcemia (underlying hypocalcemia)
Tertiary: autonomous parathyroid function after long-term hyperstimulation → hypercalcemia

Clinical Features

Onset: usually asymptomatic, slow gradual progression

System	Features
Muscle	Weakness ("ducky walk")
Renal	Polyuria, polydipsia, nephrolithiasis ("coral stones"), nephrocalcinosis
GIT	Anorexia, nausea, meteorism, pancreatitis, pancreocalcinosis, cholecystitis
Skeletal	Bone pain, osteoporosis, deformed skeleton, tooth loss, pathological fractures
Skin/Neuro	Dry skin, depression, sleepiness, confusion, itching

Diagnosis

Hypercalcemia + hypercalciuria
Hypophosphatemia + hyperphosphaturia
PTH ↑ (confirm elevated Ca twice before diagnosing)
Ultrasound, CT, MRI
Assess complications

Treatment

Acute/medical: IV isotonic saline + loop diuretics
Postmenopausal women (mild): estrogen therapy
Surgery: severe cases, solitary adenoma
Follow-up after surgery: Ca levels, renal function (6-12 months), BP, densitometry every 2-3 years, renal ultrasound every 2-3 years

10. HYPOPARATHYROIDISM

What is it?

Deficient PTH production → hypocalcemia syndrome

Etiology

Post-surgical (most common) - thyroid/parathyroid surgery
Idiopathic
Magnesium depletion
Chemotherapy
Parathyroid dysgenesis

Pathogenesis

PTH ↓ → phosphate accumulates in blood (↑) → calcium absorption from intestine ↓, bone mobilization ↓, renal reabsorption of Ca ↓ → Ca ↓ in blood

Clinical Features (hypocalcemia = neuromuscular excitability)

Trousseau's sign: "hand of the obstetrician" spasm
"Fish mouth" appearance
Opisthotonos
Laryngospasm / bronchospasm
Dysphagia, vomiting, diarrhea
Tachycardia, chest pain
Cold sweat
Depression, insomnia

Diagnosis

Hypocalcemia + hypocalciuria
Hyperphosphatemia + hypophosphaturia
PTH ↓
History + clinical features

Treatment

Diet: ↑ Ca, ↓ P
IV calcium gluconate + glucose + Mg + Vitamin D
Follow-up: After 7-10 days, check Ca; PTH every 4-6 months

QUICK COMPARISON TABLE

Feature	Hyperthyroid (Graves')	Hypothyroid	Hyperparathyroid	Hypoparathyroid
Key hormone	TSH↓, T3/T4↑	TSH↑, T4↓	PTH↑, Ca↑	PTH↓, Ca↓
Heart rate	Tachycardia	Bradycardia	Normal	Tachycardia
Weight	Loss (despite high appetite)	Gain (low appetite)	-	-
Skin	Hot, wet, sweaty	Dry, cold, pale	Dry	-
Bowel	Diarrhea	Constipation	Constipation	Diarrhea
Bones	Osteopenia	-	Osteoporosis	-
Key sign	Ophthalmopathy	Non-pitting edema	Coral kidney stones	Trousseau's sign

⚡ KEY FACTS TO REMEMBER

Graves' = TSH receptor antibodies (stimulating) - hyperthyroidism + ophthalmopathy
Hashimoto's = anti-TPO antibodies (destroying) - leads to hypothyroidism
De Quervain's = viral - triphasic (hyper → hypo → euthyroid)
Endemic goiter = iodine deficiency = TSH ↑, no antibodies
Cretinism - congenital, irreversible without early treatment
Hyperparathyroidism - "Bones, Stones, Groans, Psychic Moans" (classic mnemonic)
Hypoparathyroidism - most often post-surgical; treat with Ca + Vit D
Levothyroxine dose: 1.7 mcg/kg; elderly start at 25-50 mcg; children need higher doses
Treat subclinical hypothyroidism ONLY in pregnancy
Secondary HPT = high PTH but normal Ca (renal failure is key cause)
