Medicine 1 Flashcards
Lyme transmitted by Ixodes tick after ___ hrs of attatchment and are at ___ risk for Lyme.
How many days does it take for erythema migrans to devo?
Lyme = B Burgdorferi 36-48 hrs LOW at least 3 days for rash to devo; mostly 7-14 days Serology not positive for about 2 weeks
Derm side effects of:
Furosemide
Lisinopril:
Amlodipine
Furosemide: SJS and uticaria NOT photo
Lisinopril: Angioedema, uticaria, maybe aggravation of psoriasis
Amlodipine: see significant fluid retention and uticaria
Derm SE of these antiHTN
Metoprolol
Hydrochlorothiazides
Metoprolol: uticaria and CAN cause photosensitivity
HCTZ: photosensitivity (they are sulfa containing drugs)
Electrolyte imbalance resulting in HYPERactive DTR, muscle cramps –> convulsions
HYPOcalcemia
Why does hypoCa occur after major surgery/trauma? How does it manifest
often massive blood transfusions–> large amounts citrate use to anticoag teh blood. Citrate–Ca chelation–> low Ca
ALSO can get volume resuscitation leading to low Ca and low Albumin (generally Asymptomatic)
Sx: HYPERactive DTR, muscle cramps, convulsions
What are GI, CV changes we see with HYPERkalemia?
N/V and ECG: peaked T waves,short QT–> lengthening of PR interval and QRS –> P wave disappears–> sine wave
What happens to DTR in HYPERmag?
high Mag = LOSS Of DTR and can lead to flaccid quad, apnea, decreased respiration
mild elevation mag = increased DTR
Patient with stroke has these symptoms:
Vertigo, difficulty standing (vestibulocerebellar) and falling TOWARDS lesion and nystagmus (horizontal/vertical) + ipsilateral limbataxia
Abnormal facial sensation and loss of Pain/temp IPSILAT face and CONTRA trunk (sensory)
Dysphagia, dysarthria, hoarsness (CONT VC paralysis)= IPSI bulbar msl weakness
Ipsi Horners (miosis/ptosis/anhidrosis), hiccups, no respirations
Wallenberg syndrome
= LATERAL MEDULLARY stroke
Patient with lesions in the lateral cerebral hemisphere present with
IPSILATEARL ataxia, not dizzy and no change in sensation or temp
What vessel most commonly implicated in Wallenberg syndrome (lateral medullary stroke)
Intracranial vertebral artery
See vesibulocerebellar findings; can’t feed and overshoot targets bc of ipslateral limb ataxia.
Sensory changes; loss pain/temp in IPSIlateral face adn CONTRA trunk/limbs
Dx MRI and Tx stat thrombolytics (TPA)
PT presents with weakness in chewing (msl of mastication), diminished jaw jerk reflex, impaired tactile and position sense. Most likely location of lesion
Lateral mid-pontine
Patient presents with CONT paralysis of arm and leg, tongue deviation towards the lesions.
CONT loss of tactile and position sense
Medial Medullary Syndrome (vertebral or anterior spinal artery)
Difference btwn TIA and stroke, time/symptoms
TIA = < 24hrs symptoms resolve, from emboli or thrombus (the opthalmic artery is 1st branch of the ICA) and NEVER from hemorrhage
Stroke symptoms >24 hrs, 80% ischemia (thrombus/emboli) and 20% hemorrhage
How do you triage a stroke? Imaging and medications?
STAT head CT WITHOUT contrast (to assess for hemorrhage)
if not hemorrhage–> thrombolytics (TPA) if w/in 3 hr
Locate the lesion
LE weakness, mild upper ex weakness, personality change/pysch disturbance, urinary incontinance
Anterior cerebral artery (if one sided symptoms are CONtralateral)
Locate lesions
Profound UE weakness, aphasia, apraxia/neglect of CONT
Eyes deviate TOWARDS lesion
CONT homonymous hemianopsia (only see one side of vision field) + macular sparing
MIddle cerebral artery
Locate lesion
Patient cannot recognize anyones face (prosopagnosia)
Posterior cerebral artery
Locate lesion
Vertigo,N/V
Drop attack or LOC
sensory changes in face/scalp with ataxia and bilateral findings
Vertebrobasilar artery
Locate lesion
Ipsilateral face
Contralateral body
Vertigo/Hordners
Post inferior cerebral artery
Locate lesion:
ABSENCE of cortical deficits
Ataxia, Parkinsonian signs, Sensory deficits, hemiparesis (mostly in face), possible bulbar signs (CN IX-XII; swallowing, tongue fasciculations, emotional lability, brisk jaw)
Lacunar infarct
Patient with SOB, wt gain and hx of HTN, obesity. PE Notable for LE edema, S3 heard on exam.
Echo with LV hypertrophy, impaired diastolic filing and preserved EF
Heart fail with preserved EF
Phenomenon seen in patients with COPD which includes loss of lean muscle mass dt energy imbalance and systemic inflammation: BMI <20 and wt loss >5%
Pulmonary Cachexia Syndrome (PCS)
Viral gasto most commonly caused by:
To treat gastro outpatient…
Noro, rotavirus
resume normal diet as tolerated, not BRAT diet (low protein) and nothing high in sugar (juice causes more osmotic diarrhea) not high in fats (more gastric acid secreation)
Contraindications to DTaP?
Anaphylaxis or encephalopathy w/i 7 days of prior vaccine.
Encephalopathyd/t pertussis parts so they can still get Td
Relative contraindications are extremely high fevers >105 or seizures
