Lab/instrumental
 Decreased cholesterol
and increased
triglycerides
 Slightly increased
glucose
 Increased FT3
 Decreased TSH and
TTH
 Ultrasound of thyroid
gland
 Low levels of calcium
in secondary, high in
primary
 ECG
 Increased cholesterol
and low blood glucose
 Increased TSH and
TTH
 Decreased FT3 and
FT4
 Ultrasound Fine needle aspiration
biopsy
 Secondary- MRI of
pituitary gland
 ECG bradycardia with
low QRS complexes
 increased blood sugar
and WBC
 decreased potassium
 possible elevated liver
enzymes
 Increased levels of
cortisol rhythm
Complication
Thyrotoxic crisis
Thyrotoxic
cardiomyopathy
Toxic hepatitis
Pericarditis
Ischemic Heart disease
Myxedema coma

Prolonged treatment with
corticosteroids (bronchial
asthma, connective tissue
and other types of
autoimmune)
Ectopic ACTH- due to
bronchial or other tumour
secreting similar ACTH
substances




Pain in bones due to
osteoporosis
Secondary diabetes mellitus
Menstrual irregularities
Decreased libido in men and
women
Primary
 Due to atrophy of the
cortex and the suprarenal
gland caused by
infections, autoimmune
disease, amyloidosis
Secondary
 Due to tumours or
postpartum ischemic
infarction of pituitary
gland

GOUT
Form of inflammatory
arthritis characterised by
recurrent attacks of a red,
tender, hot, swollen joint




Crystallisation of uric acidoccur because of genetic,
diet or decreased
excretion of urate
Diet- consumption of
alcohol, fructose
sweetened drink, meat
and seafood
PRPS- mutation
Medical condition= Gout
frequently occurs in
combo with other medial
problem, metabolic
syndrome, kidney

MTP joint at base of toe is
most often affected
Can affect ankle, knees ,
wrist and elbow

– face, breasts,
elbows, lines of the
palms and
gum(increased
secretion of
melanocyte

hormone)
Reduced fat and
muscle tissue
Menstrual
disturbances
Obsese

• Eyes = episcleritis or
scleritis. More
common is the indirect
effect of
keratoconjunctivitis
sicca, which is a
dryness of eyes and
mouth caused by
lymphocyte infiltration
of lacrimal and salivary
glands.
• Heart = endocarditis,
pericarditis, L ventricle
failure,
• Renal amyloidosis as
a consequence of
untreated chronic
inflammation
• Joint damage, joint
deformity]
DMARD
ANTIFLARES
Ankylosing spondylitis- type
of arthritis where there is
long term inflammation of
the joints of the spine.

Combination of genetic

>90 of those affecting

lower back or gluteal region
Pain often severe at rest may
improve during physical

Autoimmune connective
disorders
Systemic lupus
erythematosus
Environmental
tiggergenetic factor
immune system cant clear
effectively nuclear
antigen immune
response desposition in
tissues
SLE is presumably caused by
genetic susceptibility coupled w/an
environmental trigger which
results in defects in immune
system
One of the factors associated with
SLE is vit D def
Risk factors- smoking, direct
sunlight, F sex, black Asian and
ethnicity, medication
