Q

Sensory presbycusis versus strial presbycusis vs neural presbycusis

A
  1. Steeply sloping audiogram losing higher frequencies - have trouble hearing with background noise
  2. Mild to moderate hearing loss across spectrum of frequencies - good speech discrimination
  3. Very poor speech discrimination - recommended cochlear implantation over hearing aides

Q

If concern for hearing loss what should be first and second step
What is the Weber and Rinne test

A

Observe for obstruction with cerulean, foreign body’s, TM perforations or fluid in middle ear.
SNHL from CHL testing - tuning fork
Weber test - vibrate on knee or elbow and place on forehead bridge of nose - should hear the sound everyone or in both ears. If symmetrical SNHL normal response or not at all. Unilateral SHNL will hear sound in better ear.
Patients with CHL or MHL will localize to the hearing impaired ear
Rinne test - use tuning fork then place on mastoid bone (sound #1) then external auditory meatus (sound 2).
Normal hearing - sound 2 is louder. SNHL - normal sound. CHL and MHL - sound #1 is louder than sound 2.

Types of urinary incontinence
Urgency - leakage with urgency Stress - leakage with effort or exertion - cough running Mixed - combined stress and urgency overflow - increased PVR from bladder outlet obstruction
43
Treatment for urinary incontinence
Bladder training - pelvic floor muscle exercises Antimuscarinic agents (anticholinergics) - oxybutin - biggest long term risk is cognitive impairment. Dry mouth with Consitpation

Osteoporosis definition
Bone mineral density of T <= -2.5 or minimal trauma fx in patients with osteopenia (t score of <-1.0-2.5) *lumbar spine, femoral neck, hip or 1/3 radius Severe osteoporosis is a T score of <2.5 in the presented of >= 1 fragility fracture Calculate FRAX score in patients with osteoporosis
54
Risk fractures for osteoporosis
Age Female Low body weight Physical inactivity Glucosteriods Asain ro white Smoker , alcohol use Low dietary calcium and vitamin d
55
What hormone does calcium and vitamin D deficiency increase
Parathyroid hormone which increases rate of bone reabsorption
56
When to screen for osteoporosis risk fractures
All post menopausal women and men >=50 years old
57
When should you screen for osteoporosis with BMD testing
All women >=65 years old Or women and men <65 years old with risk fractures or history of fracture. Screen all men >70 years old. * uses central bone mineral density testing
58
FRAX screen
Estimates 10 year probability of fracture at the hip or major osteoporotic fracture.
59
Prevention of osteoporosis
Excerise 5 times per week for 30 minutes - weight bearing exercises Calcium intake of 1200 (up to 2500 in heart patients is safe) , VItamin d of 600. 800 over >70. Keep vitamin D level >30.
60
Treatment of osteoporosis
All post-menopausal women, or men >50 who have osteoporosis per DEXA or fragility fracture Osteopenia with fragility fax of >3% OR MAJOR osteoporic fracture >20% >1 year life expectancy Start within 14 days of treatment Biphosphonates - decrease bone reabsorption and bone remodeling. Alendronate, risedronates Has poor absorption so must wait 30 minutes before drinking/eating.
61
Side effects of biphosphonates
GI upset Osteonecrosis of jaw Aysptical fractures - get xray if develop groin/hip pain
62
When do you discontinue biphosphantes
Drug holiday in 5 years at low risk fo fax, >-2,5 or no change on DEXA Discontinue in elderly if no longer ambulatory or have a <2 year life expectancy Denosemab —> no drug holiday as bone remodeling reverses after 6 months.
63
Greastest risk factors for Alzheimer’s disease
Age and family history
64
What causes dementia
Set of proteins within the brain affect neuronal function causing cell death.
65
What things can slow cognitive decline
Physical activity and cognitive training
66
Subjective complaints from patient or family member should be followed with cognitive assessment
67
What are the screening test for dementia
Mini-cog assessment, SLUMS (st Louis university mental statue), and Montreal cognitive assessment.
68
When should you order brain imaging on patients concerning for dementia
Not routinely used. <65 years old, sudden onset or rapid progression, focal deficits, history of fall or recent trauma.
69
Typical features of Alzheimer’s disease
Slow gradual onset with memory loss. Stage 3- recognized by family Stage 4 - medical interviewer can identify. Stage 6- need help dressing /tolieting etc.
70
Vascular dementia
Sudden or gradual, areas of ischemia/hemorrhagic, symptoms will depend on location of vascular changes.
71
Levy body
Gradual onset, typically with visual hallucinations and REM sleep disorders. Parkinson like symptoms develop later.
72
Parkinson’s Disease
Gradual develops late stage Parkinson’s
73
Frontotemporal demtnia
<60 years old. Have emotional changes, disinhibition, language issues before memory issues.
74
Primary goal of treatment with dementia
Enchance quality of life, symptom improvement not curavtive.
75
Medications for dementia
Cholinesterase inhibitors - donepezil, rivastigmine, galantamine. - slow the breakdown of achetycholine - used for mild to severe dementia. - side effects mostly GI symptoms - headaches, dizziness, orthostasis. - no role in frontotemporal dementia - stop if no improvement/rapid decline
76
Namenda
Used in moderate to severe AD CAn be used with Cholinsternase inhibitors.
77
Behavioral symptoms with dementia how to treat
Nonpharmalogical FIRSTLINE!! - reduce stimulation, redirection. Can use antipsychotics - but all carry black box warning with increased risk of mortality (seroquel better tolerated).
78
Delirium
**underlying process. Acute onset - tends to fluctuate - can last weeks to months - if >6 months likely dementia or mild neuro cognitive disorder
79
Screening for delirium
CAM test
80
Medications that can cause delirium
Anticholinergics (oxybutin, benztropine) H2 blockers (Pepcid) Bendodiapzines Opioids Antipsychotic medication Antihistamines (benadryl)
81
Treating delirium
Try to treat underlying cause Nonpharmalogical ways first - orientation to clocks, make sure hearing aides/glasses etc on. Use antiphycotics ONLY if unable to manage behaviors and causing harm to Staff and self. Do not use benzodiazepines in delirium associated with hepatic encephalopathy
82
Depression
Loss of pleasures and interest in previously enjoyable activities (anhedonia) for at least 2 weeks Depressed mood most of the day nearly every day * effects females more than males. 5-16% of the older adults live with depression
83
Screening test for depression
PHQ9 or PHQ-2 —> >10 good sensitivity depression - start treatment. >15 warrants to and physicality consult or admission Geriatric depression scale —> can be used in dementia. 5-8 mild, 9-11 mod. & 12-15 severe.
84
Must rule out other causes of depression like
Hypothyroidism, anemia, vitamin deficiency and metabolic disorders
85
Prolonged grief disorder/complex bereavement disorder
Symptoms presisted most days for the last 12 moths - preoccupation with deceased or circumstances of the death, intesense sore or emotional pain, perisisnent hearing or longing
86
Treatment of depression
Takes 4 weeks to see if peopel will respond by 12 weeks. Zoloft and lexapro usually well tolerated Paxil - highly anticholinergic *ECT is effective and preferred treatment of choice in severe depression with suicidal thoughts or not responding to treatment
87
What lab do you need to check prior to initiang SSRIS
NA level - risk of SIADH
88
Serotonin Syndrome
Worsening behaviors, diaphoretic, GI upset, fever, hyper reflex is, shivering, rhabdo, seizures
89
BIpolar 1 disorder
Persistently abnormal elevated mood - latesting at least a week - grandiosity, flight of ideas, activity, sleep decreased, talkativeness
90
Treatment for bipolar
Mood stabilizers /anticonvulsants 1. Lithium, depakote, tegretol - 2. Antipyschotics
91
Bipolar II
Hypomanic episode and past depressive episodes Hyponmaic episodes last only 4 days - no 1 week like bipolar II mania Antidepressants, steroids can cause this in older adults
