Notes from USMLE World Step CK:
Anorexia nervosa:
Pregnancy complications (assoc. chronic deprivation of essential nutrition) ↑ risk:
o Premature, small for gestational age (2/2 intrauterine growth retardation)
o Miscarriageo Hyperemesis gravidarumo Cesarian deliveryo Postpartum depressiono Poor growth and intellectual impairment
Common findings in anorexic patients: Osteoporosis ↑ cholesterol and carotene levels Cardiac arrhythmias (prolonged QT) Euthyroid sick syndrome HPA axis dysfxn anovulation, amenorrhea, estrogen
deficiency Hyponatremia 2/2 excess water drinking
OCPD
Preoccupation w/ orderliness and perfectionism, negatively impacting function Too devoted to work, stubborn, “only one way” to do
things, over-attention to detail Diffiohncculty throwing out worn items Trouble w/ relationships – need for perfectionism Need to strictly follow rules Ego-syntonic No obsessions or compulsions
Compared to OCD:Obsessions + compulsions, not necessarily on “perfectionism”
Alzheimer’s dementia
Progressive cognitive decline characterized by one or more:Apraxia – difficulty carrying out activitiesAphasia – language difficultyAgnosia – recognizing objectsExecutive fxn – planning, abstraction, organization
Compared to: Multi-infarct- HTN and heart disease are risk factors BUT requires
presence of focal neurological sx
Compared to: Pick’s dx- Behavioral and personality changes more common
becoming apathetic or disinhibitted
Refractory mania despite mood stabilizer therapy:
Management:1) Urine toxicology screen2) Mood stabilizer drug levels (especially Lithium)
Types of disordered thought & speech:Disorganized speech = common in schizophrenics (i.e. circumstantial thought process)
Flight of ideas = loosely associated thoughts rapidly move from topic to topic
Tangentiality = abrupt, permanent deviation from current subject. New thought process minimally relevant at best and never returns to original subject (more severe = loose associations)
Loose associations = Lack of logical connection between
Trichotillomania = impulse-control d/oDSM-IV criteria:
1. Repeated episodes of hair pulling noticeable2. Anxiety right before or when trying to resist3. Sense of relief after hair pulling act4. Causes impairment or distress5. Inconsistent w/ other medical or dermatological
condition causing hair loss
Affected areas: scalp, eyebrows, eyelashes, facial hair, armpits, pubic hair
Compared to: alopecia areata
thoughts or ideas of individual (more severe form of tangentiality)
- Would have “patches devoid of hair” compared to trichotillomania: “broken hair of varying lengths” w/ alopecic patches
Antisocial PD- Pattern of disregard for & violation of rights of others- Onset: middle adolescence and continues to
adulthood- Routinely engage in illegal activities (drug use, assault,
theft), endanger well-being of others and freq. lie- Superficial charm allows for manipulation of others- Aggressive, impulsive, difficulty maintaining
employment- Conduct d/o (<18) Antisocial PD
Extrapyramidal sx: Acute dystonia= due to typical antipsychotics4 hr = acute dystonia: muscle spasms/stiffness, tongue protrusions, twistin, opisthotonus, oculogyric crisis (sustained elevation of eyes in upward position)Tx: Anticholinergics (benztropine or trihexyphenidyl) or antihistamines (diphenhydramine)
Compared to other tx:Akathisia (restlessness) propranolol or beta blockersNMS dantroleneParkinson’s dx Levodopa
Hypochondriasis- Occur during periods of stress- Misinterpretation of bodily sx and persistent fear of
fatal illness despite negative medical workupsTx: Initiate discussion about current emotional stressorsBrief psychotherapy
Neurotransmitters involved:
OCD Serotonin
Bipolar d/o genetics:- Strongest genetic components of all psychiatric d/o- 1st degree relative affected 5-10% risk of developing
in lifetime- Both parents affected 60% risk- Monozygotic twin 70% risk- General population 1%
Defense mechanisms:- Reaction formation transformation of unwanted
thought or feeling into opposite- Suppression intentionally postponing exploration of
anxiety-provoking thoughts by substituting other thoughts
- Sublimination unacceptable impulses channeled into more acceptable activities
Neuroleptic Malignant Syndrome:FeverAutonomic instabilityLeukocytosisTremorElevated enzymes CPK (rhabdomyolysis myoglobinuria ARF) Tx: alkaline diuresisRigidityTx: Dantrolene (muscle relaxant) or bromocriptine (DA agonist)- Supportive care: Aggressive cooling, antipyretics, fluid
and electrolyte repletion
Treatment for schizophrenia:
1) Positive or negative sx?o Positive = hallucinations, delusions,
disorganized speech/behavioro Tx: Typical antipsychotics
o Negative = flattened affect, poverty of speech, apathy (impaired grooming& hygiene, unwillingness to perform activities), asociality (few interests, impaired relationships) and inattentiveness/concentration
Tx: Atypical antipsychotics (risperidone = less EPS SE)
Neg sx = MORE serious Disorganized schizophrenia:
o Disorganized behavior/speech, flat or inappropriate affect, rambling speech, inapprop behavior (masturbation in public, laughing at strange times)
Depot antipsychotics for noncompliant pts:
Haloperidol deconoate once every 2 weeks to once a monthFluphenazine decanoate twice a month

Bereavement vs. MDDBereavement/complicated grief < 2 months
Symptoms > 2months antidepressants + psychotherapy
MDD + psychosis vs. Schizoaffective d/oMDD + psychosis= psychosis only occurs WITH depressed mood multiple episodes > 2 wks 5+ SIGECAPS
Schizophrenia- Family therapy = most important psychosocial
intervention- ↓ likelihood relapse by ↓ conflicts/stressors in home
environment
Increased ventricular size on CT scan
Clozapine least likely to cause EPS (parkinsonism “TRAP”)- Agranulocytosis- Lowers seizure thresholdRisperidone most likely atypical to cause EPS- Switch to clozapine if EPS SE occur
