1

When is breast cancer risk increased?

If a first-degree relative has had breast cancer

2

When should a breast self-examination be used?

When the patient chooses to do a breast self-examination and the patient is trained in appropriate technique and follow-up.

3

What is the evidence surrounding breast self-examination?

The practice of BSE by trained women does not reduce breast cancer-specific or all-cause mortality. Likely increases the number of biopsies performed.

4

When should a woman get a breast exam according to the USPSTF?

Clinical breast exam should be a part of a periodic health exam, which occurs about every three years for women in their 20's and 30's and every year for women 40 and over.

5

What are the cervical cancer screening guidelines?

At 21 years of age, cervical cancer screening should begin. Between 21-29, screening should be performed every three years. Between 30-65 years, screening can be done every three years with cytology alone, or every five years if co-tested for HPV. If over 65 and has had adequate screening in the last ten years with normal paps.

6

When should women get additional screening for cervical cancer?

Women who are immunocompromised, HIV positive, have a history of CIN2-3 or cancer, or have been exposed to DES.

7

What are the risk factors of cervical cancer?

1) HPV infection (early onset of intercourse, a greater number of lifetime sexual partners) 2) DES exposure in utero 3) cigarette smoking 4) immunosuppression

8

What is "accuracy"?

High sensitivity and specificity

9

What is "sensitivity"?

Sensitivity measures the proportion of actual positives that are correctly identified as such (e.g. the percentage of sick people identified as having the condition). The more sensitive the test, the fewer false negative results.

10

What is "specificity"?

Specificity measures the proportion of negatives that are correctly identified as such (e.g. percentage of well people identified as not having the condition). The more specific the test, the fewer false positives.

11

What are the endometrial cancer screening recommendations?

At the time of menopause, all women should be informed about the risks and symptoms of endometrial cancer, and strongly encouraged to report any unexpected bleeding or spotting to their doctors. For high risk women (HNPCC for example), endometrial biopsies should be offered starting at age 35.

How do you evaluate a breast lump?

-precise location of the lump -how it was first noticed -how long it has been present -nipple discharge -any change in the size of the lump (esp. during menstrual cycle) Then follow up with a physical exam. If the lump feels cystic, aspiration can be attempted and the fluid sent for cytology. If the lump feels solid, mammography is the next step. US can distinguish a solid mass from a cystic lesion

15

21

What is the Bethesda System for reporting cervical cytology?

Cervical cytology results are given in three categories: specimen adequacy, general categorization of results, and interpretation of results. Either the Pap is negative for intraepithelial lesion or malignancy, or there is evidence of epithelial abnormalities. Epithelial abnormalities are further divided into four categories. Atypical squamous cells (ASC): Some abnormal cells are seen. These cells may be caused by an infection or irritation or may be precancerous. Low-grade squamous intraepithelial lesion (LSIL). LSIL may progress to a high-grade lesion but most regress. High-grade squamous intraepithelial lesion (HSIL). This is considered a significant precancerous lesion. Squamous cell carcinoma.

22

28

What is the controversy surrounding prostate cancer screening recommendations?

The U.S. Preventive Services Task Force (USPSTF) recommends against PSA-based screening for prostate cancer (Grade D). Based on the data reviewed, they concluded that PSA based screening in average risk males results in little or no reduction in prostate cancer related deaths and is associated with harms related to tests, procedures and treatment of the condition, some of which may be unnecessary. Other organizations, such as the American Cancer Society (ACS) recommended that physicians should have a discussion of the potential benefits and harms of screening with a PSA test.

51

What are the important historical features of ankle injury?

A patient who seeks help immediately, and is non-weight bearing is more likely to have a severe injury than one who presents a few days after an incident and is fully weight bearing (the ability to take four steps independently). A history of previous ankle sprain is a common risk factor for ankle injury. While hearing a snap or tear is diagnostically significant in an acute knee injury, it is not in an acute ankle injury.

52

What are the grades of ankle sprains?

Grading of ankle sprains takes into consideration: the presence/absence of a ligament tear, loss of functional ability, severity of pain, presence and or severity of swelling, presence of ecchymosis, difficulty bearing weight (the ability to take four steps independently) Grade I sprain involves stretching and/or a small tear of a ligament. There is mild tenderness and swelling, slight to no functional loss, and no mechanical instability. No excessive stretching or opening of the joint with stress. Grade II sprain is characterized as an incomplete tear and moderate functional impairment. Symptoms include tenderness over the involved structures, with mild to moderate pain, swelling, and ecchymosis. In this grade, there is some loss of motor function and mild to moderate instability. Stretching of the joint with stress, but with a definite stopping point. Grade III sprain is characterized as a complete tear and loss of integrity of the ligament. Severe swelling (greater than 4 cm about the fibula) and ecchymosis may be present, along with inability to bear weight and mechanical instability. Significant stretching of the joint with stress, without a definite stopping endpoint.

53

What is the most common mechanism of injury in ankle sprains?

Combination of plantar flexion and inversion. The lateral stabilizing ligaments, which include the anterior talofibular, calcaneofibular, and posterior talofibular ligaments are most often damaged. The anterior talofibular ligament is the most easily damaged.

54

How do lateral ankle sprains present?

Lateral ankle sprains generally present acutely (after trauma) with pain, warmth, and some swelling. Ankle sprains do not create a deformity. If there is a large amount of swelling present, however, it may appear to be a deformity.

55

How do peroneal tendon tears present?

Peroneal tendon tear is typically due to an inversion injury and may occur in conjunction with a lateral ankle sprain. Patient may complain of persistent pain posterior to the lateral malleolus. Swelling may or may not be present. Repetitive trauma may cause injury to the peroneal tendons

56

How do talar dome fractures present?

Talar dome fracture is usually due to acute injury. Overall prognosis is related to potential for interruption of the blood supply. Talar dome fracture may occur in conjunction with an ankle sprain, and initial x-rays may miss a talar dome fracture. Repeat imaging may be required if symptoms persist to detect avascular necrosis after talar dome fracture.

57

What are the Ottawa ankle rules?

The rules suggest that radiographs of the ankle are needed if: There is pain in the malleolar zone AND either bony tenderness along the distal 6 cm of the posterior edge of either malleolus OR inability to bear weight 4 steps both immediately after the injury and in the emergency department. Radiographs of the foot are needed if: There is pain in the midfoot region AND one of the following: (a) bony tenderness at either the navicular bone or base of the 5th metatarsal OR (b) inability to bear weight four steps immediately after the injury and in the emergency department.

Swollen unilateral superficial veins (non-varicose, in symptomatic leg): +1 point
Unilateral pitting edema (in symptomatic leg): +1 point
Previous documented DVT: +1 point
Swelling of entire leg: +1 point
Localized tenderness along the deep venous system: +1 point

GERD: classic symptoms of heartburn and regurgitation, likely to occur when gastric volume is increased (after large meals)

193

What are the complications of GERD and PUD?

GERD: Esophagitis develops when the mucosal defenses that normally counteract the effect of injurious agents are overwhelmed by refluxed acid, pepsin, or bile. Peptic strictures from fibrosis and constriction occur in about 10% of patients with reflux esophagitis. Replacement of the squamous epithelium of the esophagus by columnar epithelium ( Barrett's esophagus ) may result from reflux esophagitis. Two to five percent of cases of Barrett's esophagus may be further complicated by adenocarcinoma .

PUD: Hemorrhage or perforation into the peritoneal cavity or adjacent organs (causing severe, persistent abdominal pain). Ulcer scar healing or inflammation can impair gastric emptying leading to gastric outlet obstruction syndrome .

194

207

What are the symptoms of a right parietal infarct?

Right hand dominant patients with strokes in the area of the brain are likely to have left hemiplegia. Patients with right middle cerebral infarcts affecting the right parietal hemisphere may have difficulties with their spatial and perceptual abilities, which causes them to misjudge distance, or they may attempt to read holding books upside down. They may ignore people or objects in their left visual feild or not pay attention to that area of the room. They may also not recognize their functional impairments.

208

Stroke symptoms of other regions

Strokes that occur in the brain stem would likely be the cause of respiratory impairment and affect vital functions of blood pressure, heartbeat and consciousness.

Expressive and receptive aphasia and right facial weakness are classically associated with a left middle cerebral artery stroke.

A central nerve injury such as a stroke often spares involvement of the portion of the facial nerve that controls the forehead. This is because there is bilateral central control of this portion of the facial nerve.

A peripheral injury to the facial nerve (such as Bell's Palsy) causes facial weakness of the forehead.

209

Penicillin V (FIRST LINE), Penicillin G IM (if patient is unlikely to finish course), amox, first generation ceph, macrolides (PCN allergy) 

221

How do you diagnose and manage acute bacterial/pyogenic infection of a joint or bursa?

urgent recognition is necessary because septic joints may lead to local tissue destruction and loss of function, extension of infection locally to deeper spaces such as bone or more distinct sites by way of bacteremia

"red flags" include local complaints such as redness or swelling and/or systemic complaints such as fever, chills, and myalgias. Predisposing factors include diabetes, alcoholism, or other immune-compromising conditions

Definitive evaluation includes aspiration and culture of related fluid. Commonly staph. 

222

What are the likely diagnoses with loss of shoulder range of motion?

A patient with loss of active and passive ROM is more likely to have joint disease

A patient with loss of only active ROM is more likely to have an issue with muscle tissue.

The following joint diseases will produce restricted active and passive ROM of the shoulder:

-adhesive capsulitis: a condition common in patients with metabolic diseases in which there is contracture of the joint capsule

-glenohumeral arthritis: much less common site of osteoarthritis than the primary weight-bearing joints of the lower extremity 

-Rotator cuff injuries will compromise only ACTIVE ROM (rotator cuff tear and impingement)

223

What are the rotator cuff muscles?

224

What is the difference between tendinitis vs. tendinopathy?

tendinitis: inflammatory etiology that occurs only in the first days after an acute tendon injury; not appropriate unless injury is very acute

tendinopathy: more general term that may imply a degenerative pathology. It is a chronic condition that is characterized by a fibroblastic response, lack of acute phase reactants, and collagenous degeneration

225

What is the pathophysiology of shoulder impingement?

The supraspinatus tendon, and possibly other rotator cuff tendons, are being impinged upon by the roof of the subacromial space, which is formed by the acromion and the coracoacromial ligament. Processes that decrease the subacromial space, such as the weakened rotator cuff muscles or weakened scapularr stabilizers will promote this process. 

226

What is the order of a joint exam?

Inspection

Palpation

Range of motion

Strength testing

Special maneuvers

(not what Dr. Kapur taught, but what FM Cases states)

227

What is the differential for subacute right shoulder pain aggravated by movement?

Rotator cuff tendinopathy -- weakness and pain with empty can testing, limited active ROM

Torn rotator cuff --limited ROM with significant pain, significant weakness with strength testing

Impingement syndrome with bursitis-- limited ROM, Neer and Hawkins-Kennedy tests rule out 

Labral tear--may occur through repetitive damage from glenohumeral joint instability or secondary to frank dislocations or other trauma. Often a diagnosis of exclusion.

228

physical therapy

pain medication as needed

relative rest

234

What are the symptoms of chlamydia, gonorrhea, and trich and how do you diagnose them?

  • Patients with chlamydia present with dysuria, discharge (penile or vaginal), pain with sex, abdominal or testicular pain, breakthrough bleeding or can be asymptomatic. Diagnosis is made by nucleic acid amplification test of urine, endocervical sample, or urethral sample.
  • Patients with gonorrhea can be either asymptomatic, or have dysuria, discharge (penile or vaginal), pain with sex, abdominal or testicular pain, or breakthrough bleeding. Diagnosis is made by nucleic acid amplification test of urine, endocervical sample, or urethral sample; gonococcal culture for rectal or pharyngeal specimens.
  • Presenting symptoms of trichomonas include vaginal discharge with odor or itching, so testing for T. vaginalis should be performed in women seeking care for vaginal discharge. But trichomonas can also be asymptomatic and screening for T. vaginalis can be considered in those at high risk for infection, such as women who have new or multiple partners (the situation presented in this question), have a history of STIs, exchange sex for payment, and use injection drugs. Diagnosis is made by either saline wet mount or rapid antigen testing. 

235

What are the types of testicular tumors?

Germ cell tumors (seminomatous or nonseminomatous)-- most common primary testicular tumors. Usually seminomatous. 

Non-seminomatous are usually embyronal cell tumors, teratomas, or yolk sac tumors.

Other causes include non-germ cell tumors (Leydig cell and Sertoli cell tumors) and extragonadal tumors

236

What is the differential of groin pain in an adolescent?

testicular torsion: physical findings include a swollen, tender scrotum and the cremasteric reflex is typically absent. Testicular torsion causes the orientation of the testis to change, causing a "transverse lie".

Torsion of the testicular appendages: Appendix testis is a small vestigial structure (embryonic remnant of the Mullerian duct) located on the anterosuperior aspect of the testis. Pain is usually less severe than in testicular torsion and is localized to the region of the appendix testis without any tenderness in the remaining areas of the testis. Bluish coloration in the scrotum at the upper pole of the testis is seen.

Epididymitis: Most common cause. Symptoms are slowly progressive over several days. Caused by bacterial infection of the epididymis (UTI or STD), severe swelling and exquisite pain on the involved side with fever, rigors, and irritative voiding symptoms. On exam, scrotum is tender to palpation and edematous on the involved side. The cremasteric reflex is usually present, and the testis is in its normal location and position. 

Other less ilkely things: trauma, inguinal hernia, HSP, hydrocele, tumor, varicocele

 

237

How do you diagnose testicular torsion?

Color Doppler US-- if testicular torsion is present, intratesticular blood flow is either decreased or absent when appears as decreased echogenicity, as compared with the asymptomatic testis. 

Radionuclide scintigraphy is a diagnostic test that uses a radioisotope to visualize testicular blood flow. Patients with testicular torsion have decreased radiotracer in the ischemic testis, resulting in a photopenic lesion. 

Radionuclide scintigraphy is more sensitive, but US is faster and easier. 

238

How do you manage testicular torsion?

Orchiopexy -- surgical fixation of BOTH testes to prevent retorsion

239

What is the difference between fatigue and sleepiness?

  • fatigue - A feeling of exhaustion or tiredness that is pervasive, not relieved by rest, and often worsened by exertion.
  • sleepiness - A feeling of tiredness that gives a patient the tendency to fall asleep, and is often relieved by either rest or exertion.

240

What is the PHQ-2?

The PHQ-2 involves asking patients, "Over the last two weeks, how often have you been bothered by any of the following problems?" (1) "Little interest or pleasure in doing things." (2) "Feeling down, depressed, or hopeless." For each question, the patient can answer: "not at all" (0 points) "several days" (1 point) "more than half the days" (2 points), "nearly every day" (3 points).

 

Screens for depression

241

How can you screen for colon cancer?

Colonoscopy -- once every ten years

FOBT yearly

Flex sig-- every three years

242

How do you clinically stage colon cancer?

Clinical staging of colorectal cancer is the depth of the invasion of the bowel wall. For colon cancers, this cannot be determined until the cancer is surgically removed (pathologic staging). In the case of rectal cancers, endorectal US provides oncologists with failry accurate estimates of the depth of invasion and may guide therapy. 

Metastasis - pelvic lymph nodes, liver, and lung 

CEA - elevated in many colorectal cancers. Elevation above 5 ng/m is associated with worse prognosis at each stage. 

243

Self-reported history of COPD

Maximum laryngeal height of 4 cm or less

Age of at least 45 years

250

What are the major differences between COPD and asthma?

COPD is not reversible via bronchodilator therapy and asthma is.

COPD symptoms slowly progress, while asthma symptoms vary day to day.

COPD has more symptoms during exertion, while for asthma the symptoms are more common at night or early morning

Cigarette smoke is more of a causal agent in COPD. Mast cells, helper T cells, and eosinophils play more of a role in what appears to be an allergic bronchoconstrictive response in asthma. 

Macrophages, T killer cells, and neutrophils play a role in an inflmmatory and destructive process in COPD. 

Post-bronchodilator FEV1/FVC ratio >12% after bronchodilator.

251

What are the PFTs for COPD?

FEV1/FVC is decreased in COPD. (less than 70%)

252

What is therapy for moderate and severe COPD?

Therapy for moderate COPD: FEV1 is between 50 and 80% of predicted. Maintenance therapy of inhaled anticholinergics (ipratroprium or tiotroprium) alone or in combination with short-acting beta agonists.

Therapy for severe COPD: Symptomatic patients whose FEV1 is

Risks of overuse of beta agonists include:

tachycardia, exaggerated somatic tremor, and hypkalemia 

253

What is the differential of shortness of breath in a middle-aged man who smokes?

254

How do you define the level of COPD severity?

FEV1 of >80% is mild.

50-79% is moderate.

30-49% is severe.

255

What is a COPD exacerbation and how do you manage it?

COPD exacerbation: increased dyspnea, increased sputum volume, and increased sputum purulence

Treatment: inhaled bronchodilators and oral glucocorticosteroids 

azithromycin if infection is suspected

256

How does COPD lead to heart failure?

Chronic hypoxia causes pulmonary vasoconstriction, which increases blood pressure in the pulmonary vessels. This elevation in blood pressure causes permanent damage to the vessel walls and leads to irreversible hypertension. The right heart eventually fails because the pump cannot sustain flow effectively against this pressure. Right heart failure leads to an increase in preload, with peripheral edema and increased JVD. 

257

What are good medications for a patient with both diabetes and hypertension?

258

What are the physical exam findings for suspected heart failure?

Crackles in the lung bases and dullness to percussion. 

JVD

PMI that is laterally displaced from the mid-clavicular line towards the axillary line

S3 from rapid ventricular filling or poor left ventricular functioning.

Enlarged liver, hepato-jugular reflux, and distention and shifting dullness indicating ascites

Lower extremity edema 

Sacral edema

259

What is diastolic heart failure?

Diastolic heart failure occures when signs and symptoms of heart failure are present, but left ventricular function is preserved (ejection fraction >45%). It is caused by impaired LV filling and abnormal LV relaxation and is most commonly related to uncontrolled hypertension. The incidence of diastolic heart failure increases with age and is more common in older women. 

260

What is the pathophysiology of diastolic dysfunction?

The left ventricle develops an abnormality of filling and becomes stiffer and noncompliant as the disease progresses. Then there is increased pulmonary vessel pressure during exercise, increased filling pressure, and, as left atrial pressure and size increase, congestion. At this point, exercise intolerance increases and clinical signs of failure, particularly dyspnea on exertion, appear. Pulmonary congestion, hepatic congestion, and peripheral edema appear. 

261

Can you have systolic dysfunction without diastolic dysfunction?

No, all patients with systolic dysfunction also have diastolic dysfunction. A patient cannot have pure systolic heart failure. 

However, certain cardiovascular diseases such as hypertension may lead to diastolic dysfunction without concomitant systolic dysfunction. 

262

How do you differentiate heart failure from non-cardiac conditions in patients with dyspnea?

BNP testing can help differentiate heart failure from non-cardiac conditions in patients with dyspnea. A normal BNP effectively rules out CHF. 

263

What is the differential for new onset congestive heart failure?

MI, arrythmias (such as a fib/flutter with rapid ventricular response. Without the atrial kick, the ventricle does not fill as well, a problem that is exacerbated by the decreased filling time that occurs with tachycardia), ischemic cardiomyopathy, uncontrolled HTN

264

What radiographic findings are associated with congestive heart failure?

  • Cardiomegaly: Defined when the width of the heart is more than half of the width of the thorax.
  • Central vascular congestion and hilar fullness: Patients in failure frequently have hilar fullness on a PA chest film. Individual vessels may appear enlarged.
  • Pleural effusions: Identified by a blunting of the costophrenic angles. This can be seen posteriorly on a lateral film as well. Occasionally, prominent fluid in the horizontal fissure will be seen in the right lung.
  • Cephalization of pulmonary vasculature: Typically, pulmonary vessels are not well seen in the upper lung fields. In CHF, however, they become engorged and can be seen extending from the hilum.
  • Kerley B lines: These are small linear densities 2-3 cm in length seen in the periphery of the lung fields on the PA view. They represent interstitial fluid in the lung tissue

What are the premenstrual syndrome diagnostic criteria?

Premenstrual dysphoric disorder is a complex disorder that occurs at a specific time in a woman's cycle during multiple menstrual cycles in a year. A minimum of five symptoms need to begin the week prior to menses, start to improve during menses and then become minimal the week after menses. The patient must have one of the following: marked mood lability, irritability or anger, depressed mood or feeling hopeless, or anxiety and edginess. The patient must also have one of the following: food cravings, changes in sleep, being "out of control", decreased energy, anhedonia, and some physical symptoms. The patient must have a minimum of five symptoms out of the above groups. How these are expressed may differ based on culture and social norms for the woman. It may be helpful to get the perspective of other close contacts of the patient.

274

How do you treat PMS?

  • Danazol is an androgenic medication with progesterone effects. It lowers estrogen and inhibits ovulation. However, its multiple androgenic side effects, including weight gain, suppressing high density lipids, and hirsutism, limit its desirability among patients. GnRH agonists, such as leuprolide, are effective at treating premenstrual syndrome through ovulation inhibition. However, their anti-estrogen effects, including hot flashes and vaginal dryness, make these not as popular.
  • Oral contraceptives are effective treatment for dysmenorrhea, anovulation, and in some cases menorrhagia. While not always effective for premenstrual syndrome, they are a good place to start. It would be appropriate to try this in a woman also needing birth control. The most favorable pill is the formulation containing ethinyl estradiol and drospirenone. One study demonstrates potential improved effectiveness by decreasing the placebo pills to four days from seven.
  • Selective serotonin reuptake inhibitors during menses are an effective treatment of premenstrual syndrome, especially if severe or mood symptoms predominate. There are three effective regimens for SSRI use. One regimen is continuous daily treatment. Another is intermittent treatment, which is just as effective as daily treatment for decreasing both psychologic and physical symptoms. There are two types of intermittent treatment. One method is to start therapy 14 days prior to menses (luteal phase of cycle) and continue until menses starts. The second method is to start on the first day a woman has symptoms and continue until the start of menses or three days later. Many randomized trials have used fluoxetine and sertraline. Venlafaxine can be used as well. Lower doses are effective. If one medication does not work, another in the same class should be tried prior to considering the treatment a failure. Follow-up should occur after two to four cycles. Intermittent treatment is associated with fewer side effects and lower cost.
  • Hysterectomy is not effective for premenstrual syndrome as it does not alter hormonal balance in women. Oophorectomy, however, is a potential surgical treatment for severe refractory cases in women done with childrearing. Spironolactone is a diuretic. It has been tested mainly to control symptoms such as bloating, weight gain, and breast tenderness. In studies the effectiveness is inconsistent. If this were to be tried on a patient, the dosing would be during luteal phase. You must be cautious about causing potential electrolyte abnormalities with this drug.
  • Vitamin B6 has inconsistent data regarding effectiveness. It may be effective for mild symptoms or in women reluctant to use antidepressants. Patients should be cautioned about overdosing as this may cause peripheral neurotoxicity. Other non-drug interventions include regular exercise and low carbohydrate diets. Decreasing carbohydrates in the luteal phase may be effective for mild symptoms. Relaxation therapy has also been evaluated with mild results. These are all worth discussing with patients, although true efficacy is not proven.
