Shoulder Pain Flashcards
what muscle is responsible for flexion and supination of the arm?
biceps brachii
what muscle adducts, extends and internally rotates the arm?
latissimus dorsi
also an accessory muscle of respiration
what muscle is responsible for overhead abduction of the arm (> 90°)?
trapezius
what muscle is responsible for the first 0-15 degrees of arm abduction?
supraspinatus
what muscle is responsible for 15-90 degrees of arm abduction?
deltoid
what rotator cuff muscle is responsible for external rotation?
infraspinatus
what rotator cuff muscle is responsible for adduction and external rotation?
teres minor
what rotator cuff muscle is responsible for adduction and internal rotation?
subscapularis
what rotator cuff muscle is the most commonly injured?
supraspinatus
what rotator cuff muscle is being tested during the empty can test?
supraspinatus
AC separation
(structures that may be damaged: acromioclavicular ligament,
coracoclavicular ligament)
what is this biopsy depicting?
SCC
Solid, epithelial tumor
Intercellular bridges (arrowheads)
Keratin pearls (blue circles)
where is SCC located in the lung?
central
Naylor: “hint, it will be central and pearly white due to keratin production”
what is the MoA of cisplatin?
platinum compound that cross-links DNA
adverse effects of cisplatin [3]
nephrotoxicity
peripheral neuropathy
ototoxicity
compression of the […] ganglion of the oculo-sympathetic pathway causes Horner’s syndrome
stellate
(via mass effect from tumor)
cushing syndrome and SIADH are paraneoplastic syndromes associated with what cancer?
SCLC
Edema of the upper extremities and face (facial plethora)
Prominent venous pattern on the chest, face, and upper extremities
Jugular venous distension
are symptoms of…
SVC syndrome
Sudden onset of severe, sharp tearing chest or abdominal pain that radiates to the back
Asymmetrical blood pressure, pulse deficit
New diastolic murmur
aortic dissection
Heavy, dull, pressure/squeezing sensation
Substernal pain with radiation to left shoulder
Nausea, vomiting, diophoresis
MI
constitutional symptoms
(fever of unknown origin)
new/change in heart murmur
endocarditis
Sharp, pleuritic, retrosternal chest pain
Exacerbated by lying down; improved by leaning forward
high pitched friction rub
pericarditis
Pleuritic chest pain
Acute onset dyspnea, hypoxemia
Cough, hemoptysis
PE
Associate […] features with aortic dissection risk
marfanoid
tall stature, long limbs (with an increased limb length to body height ratio), overcrowded dentition with a high-arched palate, arachnodactyly (long, slender fingers), and joint hypermobility.
(past medical history items may include retinal detachment, CNS aneurysm)
A high-pitched, blowing, diastolic murmur is a typical finding in patients with […]
aortic regurgitation
(can occur in aortic dissection because aortic dilatation prevents leaflets from closing properly)
Deformity of the chest wall (pectus carinatum or pectus excavatum) is a common finding in patients with […] syndrome
Marfan
Aortic dissection most commonly occurs secondary to […]
hypertension
An aortic dissection is typically caused by a tear in the […]
tunica intima
externally rotate the humerus [2]
infraspinatus
teres minor
innervates the supraspinatus muscle and infraspinatus muscle
suprascapular n.
deltoid is innervated by
axillary
trapezius is innervated by
accessory
serratus anterior is innervated by
long thoracic
main internal rotator of the shoulder
subscapularis
immunohistochemical markers for neuroendocrine tumors [3]
enolase
synaptophysin
chromogranin A
most common lung cancer among those who have never smoked
adenocarcinoma
most common type of lung cancer
more prevalent in women
adenocarcinoma
Round nodules of varying sizes scattered throughout the lungs (“cannonball lesions”) suggest […]
pulmonary metastases
The types of lung cancer most strongly correlated with cigarette smoking are [2]
SCC
SCLC
