what are some characteristics of this PD?
enjoyable to talk to while in the room, but you feel exhausted when walk out of room (like pt “sucks the life out of you”)
if pt feels you went against them, they will turn on you
- Mood instability
- Aggression
- Tendency to intense anger
- Impulsivity
- Frequent self injury
delerium
vs
psychosis
vs
dementia
►delerium (medical/toxins)→ reversible
hypoglycemia, menigitis, stroke, hypoxia, Na, alcohol
vs
►psychosis (impaired contact with reality-psych)
vs
►dementia (slow onset/ memory & coginition impairment)
parkinsons, alzheimers, repetitive trauma (soccer player)
What is porphyria?
(and why is on your differential for intoxication)
Porphyrias are inherited defects in the biosynthesis of heme.
Possible S/ Sx of acute porphyria include:
- Severe abdominal pain/ distension
- Pain in your chest, legs or back
- Constipation or diarrhea, Vomiting
- Insomnia
- Heart palpitations, High blood pressure
- Anxiety or restlessness
- Seizures
- Confusion, hallucinations, disorientation or paranoia
- Breathing problems
- Muscle pain, tingling, numbness, weakness or paralysis
- Red or brown urine
Acute psychois + physical finding (good patterns to remember):
Fever/Alcoholism/Headache/abdominal pain/sweating/automonic signs + psychosis ⇒
- Fever and psychosis : Meningitis
- Alcoholism and psychosis : Wernicke’s
- Headache and psychosis : Tumor/ICH
- Abdominal Pain and psychosis : Porphyria
- Sweating and psychosis : Hypoglycemia, DTs
- Autonomic signs (Dizziness, sweating, palpitations) and psychosis : Toxic or metabolic encephalopathy
Life threatening medical conditions that can masquerade as psychosis?
- hypoxia
- CNS infection
- CNS trauma
- Intoxication
- Etoh/drug withdrawal
- Hypoglycemia
- Hypoxia
- ICH
- Poisoning: acetominophen/salicylates/TCAD/etc
- Seizure disorder Acute organ system failure
How do you evaluate a pt that has been sent to you for medical clearance (r/o organic causes)?
vitals okay
can’t be intoxicated (functionally)
can’t be suicidal/ homicidal
ABCDEs
full neuro exam (including vision)
oriented to person, place, time→full MMSE if abnormal answers
► REASSESS before discharge
Functional vs organic (psych vs medical…)?
Medical: visual halluncinations common
- without psych Hx
- Age <12 years >40 Years old

**Security guard will sit outside room until seen by psych
If considering delerium, psychosis, which lab values should you always get?
always get a glucose and oxygen level, a urine alochol/ toxicolgy test
Besides a calm, non-imposing manner, enlisting a security guard and potentially using restraints, what might you use to keep an agitated pt calm? (pharmacologic)
Ativan 1-2mg for: Agitation, mania, withdrawal, sympathomimetics
Traditional antipsychotic: Haldol 5-10mg
Atypical Antipsychotics: Zyprexa 5-10mg po/IM
B52: benedryl, 5mg Haladol, 2mg Ativan
►B52 (will knock pt out for ~8hrs, so be prepared to have them stay)
to Dx panic disorder, must exclude:
MI
hypoxia
ischemia (stroke)
seizures
grand mal seizure= generalized (tonic→clonic→postictal)
petite mal= abscence seizure
focal= partial seizure
generalized=
tonic: loss of consiousness, fall, respiratory arrest ~1min
clonic phase: jerking, +/- tongue biting, incontinence 1-3min
postictal:sleepy, headache, N/V, myalgias 15-60min
focal= risk of tumor
1st time seizure w/u:
Tx?
- fever
- CT (bleed)
- EKG
- pregnancy (for Tx options)
- Ca, Mg, Na, K, glucose, CBC, tox screen
- lumbar puncture with SAH, fever or immunocompromised
- loss of consciousness, bowel/bladder control
Can go home wihtout any meds if stablized, but need neuro f/u with EEG. No driving.
If known history of seizure, what 2 labs need?
check blood levels of anti-seizure meds and glucose
If seizing for 5+min continuously or if more than 1 seizure without recovery inbetween (status epilepticus), what things must you do?
MUST stop seizure bc pt is anoxic!
ABC’s, IV, O2, monitor, labs, urine tox, temp
1st line: lorazapam→diazapam (benzos)
2nd: phentoin (Dilantin)
refractory: use barbituates or propafol, midazolam
Pearls: if not sure if psycogenic or real seizure, can measure prolactin
60 min post-seizure:
►prolactin up and anion gap with low bicarb if real seizure
Criteria for febrile complex seizure:
complex seizure lasts >15 min, multiple seizures, postictal period, focality, outside of 6m-5yr age group
Heavy use of what drug is linked to stroke in younger people?
heavy pot smokers
What are some medications with behavioral modifications?
Steroids- hyped up
TCAs
Anticonvulsants
Benzos- sleepy
Amphetamines/related drugs
Narcotics
Antidysrhythmics
Street drugs – alcohol, cocaine, meth
Tests vary hospital to hospital, but which toxins can be screen for (and from which sample type)?

Urine: (drugs of abuse) -
- amphetamines

-
Passive suicidal ideation
- absence of a specific plan
-
Active suicidal ideation
- specific plan regardless of viability of the plan
-
Suicide attempt
- act of self harm with intent to die
- Taking a lot of Tylenol or cutting in line with arteries/veins is very high intention/risk
-
Suicidal gesture

Todds Paralysis: focal paresis after seizure can indicate what as the cause of the seizure?
a focal cerebral lesion
How long will it take alcohol to be eliminated from body?
Metabolized by the liver, by alcohol dehydrogenase
►Steady state of elimination 15-40 mg/hour
If at 300 and need to get to 100, increments of 40mg/hr, will take at least 5 hours…
Why should most women drink less alcohol than male counterparts?
Women have less alcohol dehydrogenase, so slower metabolism
Women have less gastric metabolism than men
What are general symptoms of alcohol withdrawal?
PE: Hyperadrenergic state
►Life threatening!
(HTN, tachycardia, diaphoresis, agitation, tremor, mild fever, hallucinations (visual) and possibly seizures)
Tx of alcohol withdrawal:
- Evaluate for co-morbidities (head CT, LP and CXR)
- Correct fluid and electrolyte imbalances
- Meds: usually benzos. May require large doses.
- ¨Ativan 1-4mg IV q hour to effect. (Start with 2mg)
- ¨Tranxene 15-30 mg PO Q 6-8 hours for discharge
- Will be asked by detox to send pt to them with a “6pack of Tranxene”
- ¨May require Beta-blockers or Clonidine to blunt adrenergic effects
- ¨Haldol to help with hallucinations, prn
Signs of methanol consumption
Metabolizes to Formaldehyde
- Increased Osm Gap
- Accumulates in the retina→ edema; visual “snowstorm”
- GI irritant
- CNS changes
