Q

tx rheumatoid arthritis

A

DMARDs - hydroxychloroquine, plaquenil, leflunomide
Sulfasalazine- se low sperm count
Methotrexate- zostavax not to be given until 4 weeks after stopping, do not start within 2-4 weeks of receiving zostavax

Biological DMARDS- humira, cimzia, enbrel, simponi, remicade

PT: relieve pain (NSAIDS/systemic steroids), reduce inflammation, preserve joint, reduce CV risk

Q

Dx osteo arthritis

PE:
Radiology:

A

Dx: Subjective and visual inspection
Trendelenberg test- stand on one foot, pelvis points down to unaffected side (gluteal weakness)
Heberdens nodes
Xray- shows osteophytes, joint space narrowing, subchondral sclerosis, cysts
MRI- not necessary, may show early stages of defects
U/S- shows synovial inflammation, effusion

Q

lyme- tick must feed for?

A

24-48 hours

18
Q

Lyme

pt presentation in three stages

A

Early localized (3-30 days): skin lesion (erythema migrans), with or without symptoms

Early disseminated (weeks-months): multiple lesions, skin, heart, musculoskeletal, nervous system changes, persistent fatigue

Late (months-years): arthritis (especially monoarticular arthralgia in knee) + neuro (encephalopathy, polyneuropathy)

19
Q

Lyme dx
serology, when does it show?

-

A

Dx: lyme antibody through serological testing- may not show for one month and may be positive indefinitely
ELISA (enzyme linked immunosorbent assay) with B burgdorferi antigens
IgM: within first few weeks
IgG: within one month
Immuno blot (Western blot) CONFIRM specificity
IgM 2-3 bands +
IgG 5-10 bands +

20
Q
Lyme tx (meds) 
med in pregnancy: 
Resolves within?
Pain/fatigue persist for?
Symptoms longer than 6 months called?
A

Tx: early disease- doxycycline, amoxicillin, cefuroxime 2-3 weeks
Pregnancy: amoxicillin 2-3 weeks
Jarisch-herxheimer reaction- transient rx, worsening sx (antigens released from dying organisms)
If tx early with abx resolves within 20 days
Pain and fatigue may persist for weeks to months (resolve by 6 months)
Symptoms longer than 6 months is called “post-lyme disease”- difficult to treat

21
Q

Anemia definition

Is anemia a disease?

Three root cases of anemia:

A
Anemia basics: reduced oxygen carrying capacity
-not a disease, sx of another issue
	Poor RBC production
	RBC destruction
	Blood loss
22
Q
Anemia labs
Most accurate indicator of anemia? 
Define: 
Hgb-
Hct-
MCV-
MCH-
RDW-
Reticulocyte-
Poik-
Aniso-
A

HGB** most accurate, less volume dependent- no sx until below 10
Hgb: oxygen carrying
Hct: proportion blood containing RBC (%)
MCV important- red blood cell size
MCH- color, concentration RBC
RDW- variation in sizes, blood cell lives 120 days, iron deficiency anemia increased
Reticulocyte- baby blood cell, normally lose 1% a day hence normal reticulocyte 1%
Poik- abnormal shape
Aniso- divergent blood cell sizes (correlated with rdw)
MCV<80- micro MCV >100- macro

23
Q

Anemia often presents_____

A

asymptomatic

24
Q

S/S anemia

severe s/s anemia

A

Exertional dyspnea, fatigue, headache, tachycardia, palpitations,
pallor (skin/conjunctiva), systolic flow murmur

Severe anemia: angina, glossitis, roaring in the ears,
muscle cramps, phagophagia (craving for ice),
pica, spooning/ridging/thinning of nails, cheilitis

25
Q

s/s pernicious anemia

A

neurological symptoms- loss of position

/vibration sense, balance, memory (can’t dx dementia without checking B12)

26
Q

Iron deficiency anemia lab findings

A

low ferritin (iron stores) **most specific
high- TIBC (“empty baskets that carry iron”
MCH and MHCH decreased
RDW increased
Ferritin- decreased, dx: IDA
Reticulocyte low- body doesn’t have building blocks to make new RBCC

	If IDA in male- suspect GI blood loss
27
Q

Tx iron deficiency anemia

monitoring anemia improvement with lab work shows improvement with 1) 2) 3)

tx until?

A

Ferrous sulfate- take on empty stomach with OJ

Monitoring: reticulocyte will improve first (body making new RBC), then H+H improved at 6 weeks, finally ferritin

Tx until ferritin normal (12 weeks)
28
Q

Thalassemia
abnormal production of ___

Minor common in ___

A

Genetic defect- abnormal hgb production

Minor- most common mediterranean, middle eastern, african, asian

29
Q

Dx thalassemia

labs
definitive dx

A

NORMAL RDW and iron studies
Microcytic and hypochromic like IDA (decreased MCV, MCH)
Definitive dx: electrophoresis increased hgbA2

30
Q

Sideroblastic anemia
disorder of???
how do you get it?

CBC/labs show?

A

Enzyme d/o- enough iron but cannot incorporate into hgb- lays down in a ring

Hereditary or acquired (ETOH, INH, RA, lymphoma, leukemia)

	Increased ferritin and Fe (IRON OVERLOAD)**
	Peripheral smear- ringed sideroblast***
	Hematology for bone marrow aspiration
31
Q

Anemia of chronic disease
associated with?

CBC/labs?

Tx?

A

Associated with inflammatory disorders, malignancy, HIV
