- SSRIs are the most effective pharmacologic agents for treating generalized anxiety disorder.
How do you treat allergic rhinitis?
- Intranasal corticosteroids are the most efficacious therapy
- Oral second-generation (nonsedating) antihistamines (for example, fexofenadine) can either be used alone or as additional therapy for control of mild symptoms, but not as effective with severe symptoms.
- Oral decongestants, including pseudoephedrine, also relieve nasal congestion but not rhinorrhea, itching, or sneezing.
How do you manage hypertriglyceridemia?
- In patients with a triglyceride level between 200 mg/dL and 500 mg/dL (2.26 and 5.65 mmol/L), the need for medication to lower the triglyceride level is determined by calculating the non-HDL cholesterol level.
- When a patient has a high triglyceride level as well as a non–HDL cholesterol value that is more than 30 mg/dL (0.78 mmol/L) above the LDL cholesterol goal, medication is indicated to treat the high triglyceride level as well as the dyslipidemia associated with it.

What is the clinical description?
What are the s/s?
How do you treat it?
What is the next intervention if the pt does not respond to treatment?
- Refers to a recurrent cough triggered when mucus draining from the sinuses through the oropharynx triggers cough receptors.
- Most patients with UACS have symptoms or evidence of one or more of the following: postnasal drainage, frequent throat clearing, nasal discharge, cobblestone appearance of the oropharyngeal mucosa, or mucus dripping down the oropharynx.
- First-generation antihistamines, in combination with a decongestant, are the most consistently effective form of therapy
- The avoidance of allergens and daily use of intranasal corticosteroids or cromolyn sodium are recommended for patients with allergic rhinitis.
- Patients who do not respond to empiric therapy should undergo sinus imaging to diagnose “silent” chronic sinusitis.
How do you treat delirium in a terminally ill patient?
- initiate haloperidol
- Antipsychotic medications in small doses are effective treatment for delirium in a terminally ill pt.
- As benzodiazepines, including lorazepam, can cause or worsen delirium, they should only be used if there is a strong component of patient anxiety or if the antipsychotic medication is ineffective after upward titration.
How do you manage a pt interested in smoking cessation?
For smoking cessation, bupropion and nortriptyline appear to be equally effective and of similar efficacy to nicotine replacement therapy but less effective than varenicline.
How do you manage recurrent falls in an elderly patient?
- Check serum 25-hydroxyvitamin D level
- If the vitamin D level is low, this patient should take ergocalciferol or cholecalciferol, 50,000 units weekly for 6 to 8 weeks, followed by 800 to 1000 units of vitamin D daily along with calcium supplementation (at least 1200 mg of elemental calcium [diet plus supplementation]).
- Although vitamin D deficiency is common in the elderly, routine vitamin D level screening is not recommended.
- Vitamin D plus calcium supplementation is recommended for all elderly persons.
What are symptoms of low vitamin D level in the elderly?
muscle weakness, functional impairment, and increased risk of falls and fractures.
An elderly pt comes to the office with complaint of one episode of fall recently. What is your initial intervention?
Patients who report a single fall should undergo balance and gait screening with the “get up and go” test. This test is appropriate for screening because it is a quantitative evaluation of general functional mobility. Persons are timed in their ability to rise from a chair, walk 10 feet, turn, and then return to the chair. Most adults can complete this task in 10 seconds, and most frail elderly persons, in 11 to 20 seconds.
What is the function of hip protectors in the elderly?
A Cochrane systematic review concluded that hip protectors are ineffective in preventing hip fractures in elderly persons who fall, partly as a result of limited patient acceptance and adherence because of discomfort.
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS)
How does it manifest?
What is the treatment?
- CP/CPPS is manifested by genitourinary/pelvic pain and voiding symptoms.
- There are no diagnostic physical or laboratory findings. Urine cultures are typically negative, and the presence or absence of leukocytes in the urine has limited clinical utility in diagnosis or in predicting treatment response.
- Alpha-blockers such as terazosin are most appropriate.
What is the preferred method?
What about the usual contraindications to OCPs?
Is a routing follow-up visit required?
- Two types of pills are available for emergency contraception. Both must be taken as soon as possible, or within 5 days of a risked pregnancy, and a second dose is taken 12 hours later.
- Levonorgestrel (Plan B) is the preferred formulation of emergency contraception because it is more efficacious and has fewer side effects (nausea 20% and vomiting 6%) than the other option, which is a combination of ethinyl estradiol and levonorgestrel.
- The usual contraindications to oral hormonal contraceptives are not applicable to women using the two-dose method for emergency contraception. Specifically, emergency contraception with oral levonorgestrel is believed to have acceptable risks in patients with cardiovascular disease, thrombophilic disorders, migraine, liver disease, and for patients who are breastfeeding.
- A routine follow-up office visit is not required after taking emergency contraception with either of these two methods.
1. What is scleritis?
2. What is episcleritis?
- 1. a serious eye condition that can lead to permanent visual loss or globe rupture and should be treated urgently in consultation with an ophthalmologist. Presents with severe bilateral eye pain that is described as deep and boring, and has associated photophobia, tearing, and eye findings of raised erythema localized to the sclera.
- 2. an inflammation of the superficial blood vessels overlying the sclera. Patients may present with no symptoms or mild ocular pain and redness, which may occur abruptly. The blood vessels appear prominent and engorged, but normal white sclera may be visible between the blood vessels, helping to distinguish this from scleritis.
What is the appropriate herpes zoster vaccination strategy?
It is indicated in all patients age 60 years and older without contraindications, regardless of history of prior chickenpox infection.
What is piriformis syndrome?
The piriformis syndrome is a condition in which the piriformis muscle irritates the sciatic nerve, causing pain in the buttocks and referring pain along the course of the sciatic nerve. This referred pain, called "sciatica", often goes down the back of the thigh and/or into the lower back. Patients generally complain of pain deep in the buttocks, which is made worse by sitting, climbing stairs, or performing squats
A common source of sciatic nerve pain resulting from irritation and hypertrophy.
- A likely diagnosis in patients with sciatic pain when examination findings localize to the sciatic notch and there are no other signs of neurologic compromise of the piriformis muscle.
- The management is conservative, with NSAIDs and stretching exercises.
How do you confirm trochanteric busitis?
can be confirmed in patients in whom hip adduction intensifies the pain or in those in whom the examination reveals pain and tenderness over the bursa, which is located over the lateral projection of the greater trochanter.
How do you evaluate pulsatile tinnitus?
- Patients with frequent or constant pulsatile tinnitus should be referred for otorhinolaryngologic evaluation and may require CT angiography or MR angiography.
- Often vascular in origin and may be due to an arteriovenous fistula, arteriovenous malformation, arterial aneurysm, tumor, or atherosclerotic disease.
How do you manage olecranon bursitis?
Olecranon bursitis is typically associated with painful full elbow flexion; acute crystalline or infectious synovitis is usually associated with pain on any passive joint motion.
When is screening for Fasting blood sugar recommended?
Fasting blood sugar (FBS) for screening purposes is recommended for patients with hypertension according to the USPSTF, because lower blood pressure goals reduce cardiovascular risk in patients with diabetes. Similarly, screening for type 2 diabetes in adults with dyslipidemia should be considered because diabetes is one of the conditions that lowers LDL cholesterol target levels. The American Diabetes Association (ADA) recommends a screening FBS in adults older than 45 years and in those 45 years or younger if they are overweight (BMI ≥25) and have one or more additional risk factors for diabetes. The ADA recommends that adults older than 45 years who have normal weight and no risk factors should be screened every 3 years; adults of any age who are overweight and have additional risk factors should be screened annually.
What is a cholesteatoma?
- a growth of desquamated, stratified, squamous epithelium within the middle ear. It is typically visible on otoscopy as an opaque or ivory colored mass behind the tympanic membrane. With growth, the cholesteatoma may erode the ossicles, resulting in a conductive hearing loss. If left untreated, erosion into the inner ear may cause sensorineural hearing loss. Patients may present with otorrhea, pain, hearing loss, or neurologic symptoms.
What is otosclerosis?
- a bony overgrowth that involves the footplate of the stapes, eventually resulting in total fixation and inability to transmit vibration from the tympanic membrane along the ossicular chain. This results in a gradually progressive conductive hearing loss.
What is Eustachian tude dysfunction?
Eustachian tube dysfunction can cause muffled hearing and intermittent popping sounds in the ear. The Weber test is typically normal.
What is "sudden sensorineural hearing loss?"
is defined as hearing loss that occurs in 3 days or less. Patients often report immediate or rapid loss of hearing or find that they cannot hear upon awakening. Approximately 90% of patients have unilateral hearing loss, and some have tinnitus, ear fullness, or vertigo. Weber test lateralizes to the good ear.
What is the diagnostic criteria of bulimia nervosa?
- Diagnostic criteria for bulimia nervosa are episodes of bingeing with loss of control occurring a minimum of two times per week for 3 months, followed by purging or other compensatory behavior.
- Patients with bulimia usually have normal weight, but many have depression or anxiety.
- Clues for the presence of bulimia include low serum potassium or high serum bicarbonate levels in otherwise healthy patients.
What is the diagnostic criteria for anorexia nervosa?
