Q

Differential diagnosis-definition

A

distinguishing between two or more diseases with similar symptoms by systematically comparing their signs and symptoms

Hints:

  • Consider the duration of symptoms (i.e. cough for 3 months has different differential dx than cough for 1 week)
  • Consider the statistical likelihood of a given problem in your patient (i.e. think about age, sex, race, habitus, lifestyle….a 40 year old male with abd pain probably doesn’t have a uterine cyst)
  • Don’t overlook potentially treatable conditions, OR potentially life-threatening conditions
  • Think about zebras
  • Might need another evaluation from a different provider or a specialty consult
  • Might need lab results, diagnostic tests…or you may never find out exact cause and you may just have a presumptive diagnosis. Don’t jump to conclusions – be careful about labeling someone with a disease they don’t have (i.e. dx of HTN is different from diagnosis of elevated blood pressure). Can use symptoms as diagnosis if you’re not sure

Example: a farmer with nausea, headache, and weakness could have virus, Lyme disease, food poisoning, hangover, heat exhaustion, medication reaction, pesticide poisoning, pregnancy

Q

Diagnostic testing-why order them

A

To make a diagnosis
To identify subclinical disease
To help form a prognosis
To monitor therapy
Always ask: Will the test change the treatment plan?

Considerations:

Interpret in light of what is already known about patient
Tests are not perfect
Tests should provide additional information
Test results should influence patient care

Test should be cost effective

Q

Sensitivity

A

Sensitivity is the probability that an individual with the disease will test positive (few false negatives)

SNout (rules out)

for this reason, SCREENING TESTS given to the general population need to have high sensitivity; ex: enzyme-linked immunosorbent assay (ELISA) is a high-sensitivity initial screening test for HIV/AIDS à performed x 2 and those who test positive are then given a diagnostic test

(TP/all who have the dz(TP+FN))

Q

Specificity

A

Specificity is the probability that an individual without the disease will test negative (few false positives)

SPin (rules in)

DIAGNOSTIC TESTS (given to specific individuals identified as at risk by initial screening tests) need to have high specificity; ex: western blot test used to dx HIV/AIDS in individuals who tested positive on the ELISA

TN/all who do not have dz(TN + FP)

Q

NNT

A

In clinical treatment regimens, the number of patients with a specified condition who must follow specified regimen for a prescribed period in order to prevent occurrence of specified complication(s) or adverse outcome(s) of the condition”

Inverse of the absolute risk reduction
Perfect NNT is 1
The higher the NNT, the less effective is the treatment

Should be understood within the CONTEXT provided (eg., prevention context)

e.g., drug saves 2% of people – so need to treat 50 to save 1.

Q

Relative risk

A

Relative Risk (aka Risk Ratio)

Probability of an outcome for someone with the risk, relative to the outcome for someone without the risk
When RR = 1 → no association between risk & outcome

RR can only be calculated when population data available for all patients of interest (ex: in a cohort study); by contrast, if only sample data is available (ex: in a case-control study), then odds ratio (OR) is used to estimate relative risk

Q

Recommended weight gain in pregnancy: where does it come from?

A

Most: uterus and its contents, the breasts, and increases in blood volume and extravascular extracellular fluid

The rest: metabolic alterations that result in an increase in cellular water and deposition of new fat and protein—so-called maternal reserves.

33
Q

Physical exam at first prenatal visit

A

ROS and focus on: Mouth-dental health (infection), Thyroid, lungs, breasts (hormonal changes can cause some breast cancers to grow more rapidly), lymph nodes, Heart, abdomen (includes FH (fundal height)/leopolds/FHTs); Pelvic: samples for Pap, GC./CT; bimanual exam for uterine sizing & pelvimetry; extremities for edema, varicosities (clotting factors increase, esp in 3rd T)

34
Q

Exercise and pregnancy

A

horough clinical evaluation be conducted before recommending an exercise program. I

n the absence of contraindications, pregnant women should be encouraged to engage in regular, moderate-intensity physical activity 30 minutes or more a day.

Activities with a high risk of falling or abdominal trauma should be avoided.

Scuba diving should be avoided because the fetus is at an increased risk for decompression sickness.

35
Q

UTI’s and pregnancy

A

assoc w/preterm or low birth weight infants

36
Q

Hgb electrophoresis results in pregnancy

A

at first prenatal visit if at risk: looking for sickle cell and thalassemia traits.

  • increased risk of spontaneous abortion, stillbirth, and preterm labor. Therefore, ACOG recommends that serial ultrasonography and antepartum fetal testing be performed.
37

64
Q

Predictive Values

A

PPV, NPV

65
Q

Recommended weight gain: normal BMI

A

Women with optimal pre-pregnancy weight (BMI 18.5-24.9) should gain 25-35 lbs.

Usually, 3 - 6 lbs. are gained total in first trimester, and ½ to 1 lb / wk in the remainder.

If pt. does not show a 10-lb weight gain by midpregnancy, assess her nutritional status, unless she is obese.

Inadequate weight gain = risk for LBW, especially if mother was normal or underweight.

66

Recommended weight gain in pregnancy: underweight women

A

Underweight women (BMI <18.5) can gain up to 40 lbs.

67

Overweight women (BMI 25-29.9) should gain no more than 15 lbs.

68
Q

Recommended weight gain in pregnancy: morbidly obese

A

Morbidly obese women (BMI >40) do not need to gain weight.

69
Q

Pregnancy: what to do in case of weight loss or excess weight gain

A

When excess weight gain is noted, counsel pt. regarding nutrition & physical activity.

Rapid weight gain requires an assessment for fluid retention.
Don’t limit fluids! Don’t restrict salt unless pt. has HTN.

*Patients should be cautioned against weight loss during pregnancy.

73
Q

Murmurs in pregnancy: management

A

Any diastolic murmur and any systolic murmur that is loud (grade 3/6 or higher) or radiates to the carotids should be considered pathologic.
