10 Differences...let me count the ways

11 I can go from normotensive to hypotensive in a heartbeat. Things Geri-pts say My subdural haematoma hasn t expanded enough yet to really affect my level of consciousness. Trauma is not really my major problem. I get demand ischaemia if I have too much pain or my haematocrit drops or I can t stand even a little shock or hypoxia and neither can my myocardium. The sensitivity of my abdominal examination is better that flipping a coin but not much. A little medication goes a long way with me Major trauma? Heck, I wouldn t even tolerate a brisk haircut. My injuries weren t accidental.

21 Advice #1 Clinical atypical is typical

22 worst-first approach

23 Clinical atypical is typical Late presentation -physiology -fears independence/ death History will be difficult VS Bloodwork

24 Clinical atypical is typical Acute Cholecystitis WBC 40% LFTS 30% Afebrile 50% Appendicitis/Diverticulitis WBC 50% Afebrile 50% Exam: non-specific ACS AMS

33 Dizzy Dix-Hallpike It is a misconception that vertigo that is worsened by head/body movement (including Dix-Hallpike maneuver) is the result of a peripheral cause such as BPPV. However, the exacerbation of symptoms with head movements have been reported in all causes of vertigo (Kubo, 1988). Others experts argue that patients with dizziness from ANY cause will feel worse with certain position changes (Kerber, 2009). Therefore, the characteristic that distinguishes BPPV is not simply an exacerbation of vertigo by head movement, but rather, vertigo that is triggered by positional changes, lasts less than one minute, and then returns to normal between attacks (Kerber, 2009). otic symptoms (hearing loss, tinnitus, ear fullness, etc.), which strongly suggests peripheral etiology however recent hyper-extension injury ortrauma associated with neck pain Hard focal neurological signs (i.e., hemiplegia, hemisensory loss, ataxia, dysarthria, ophthalmoplegia, etc.) clearly point to a central etiology, but unfortunately are found in only approximately 50% of patients with posterior strokes

34 Dizzy Nystagmus of peripheraletiology is generally found to be horizontal in nature and unidirectional Head Impulse testing, bi-directional Nystagmus, and Test of Skew. In their prospective, crosssectional study, they performed the HINTS exam at the bedside of 101 patients in an academic hospital stroke center to try and differentiate between those patients with central versus peripheral etiologies of their vertigo. Later they confirmed their diagnoses using MRI with diffusionweighted imaging. They concluded that the presence of either a normal horizontal head impulse test, direction-changing nystagmus in eccentric gaze, OR skew deviation was 100% sensitive and 96% specific for stroke. Patients with central vertigo must have at least one of the 5 Ds (Dizziness, Diplopia, Dysarthria, Dysphagia and Dysmetria) or long tract signs. Stroke may present as isolated vertigo with only minor gait disturbance without any of the 5 Ds or long tract signs. #2: Unidirectional nystagmus is always a sign of peripheral vertigo. While unidirectional nystagmus usually points to a peripheral cause, it can occur with central causes of vertigo. Unidirectional nystagmus does not, on it s own, rule in a peripheral cause. If nystagmus is definitely multidirectional, or purely vertical with no rotatory component the cause is almost certainly central. The HINTS exam can help differentiate a peripheral vs. central cause of acute vestibular syndrome, although this is not perfect

35 4 types of vertigo (based on duration of symptoms): Less than 60sec: Positional event (MARKEDLY worse with movement) Minutes (few to 30): If not positional: migraine (in young, low-risk patients) or TIA/CVA (in older, at-risk patients) Many hours: Vestibulopathy, Ménière s disease Days: Labyrinthitis, or stroke Crossed syndromes, consisting of ipsilateral cranial nerve dysfunction and contralateral long motor or sensory tract dysfunction are highly characteristic of posterior circulation stroke CT but MRI!!
