MUST LISTEN (re ABEM)

ABEM-style cases presented on EM Clerkship are not my actual ABEM exam cases, and they are not derived from my actual exam cases. I will never be discussing my specific exam details with anybody, including on this podcast. The cases were created independently, by me, for the purpose of medical education and improving patient care. Topics are chosen from the publicly available ABEM model of clinical practice and are built from scratch using a my own custom template. If you would like a copy of this template, please email me and I can send you a copy.

ACS, Acidosis, AAA and Other Miscellaneous Causes of Abdominal Pain

There are HUNDREDS of other non-GI/GU causes of abdominal pain…

Acute coronary syndrome (ACS)
  • Test with EKG and troponin
  • Treat with aspirin and heparin
Acidosis
  • Diabetic Ketoacidosis (DKA)
  • Respiratory Acidosis (COPD)
  • Salicylate Toxicity (Remember MUDPILES)
Abdominal Aortic Aneurysm (AAA)
  • Older people with abdominal/flank/back pain or syncope
  • Testing
    • CT Scan Abdomen with contrast (Good)
    • CTA Abdomen (Better)
    • Bedside Ultrasound (Best)

Testicular Torsion and Prostatitis

Testicular Torsion

History
  • Pain in the testicles
  • Referred pain in the flank or lower abdomen
  • Usually sudden and severe
  • Usually WITHOUT urinary symptoms
Exam
  • Asymmetric testicular lie
  • High riding testicle
  • Tenderness and swelling of the testicle itself
  • Cremasteric reflex
Testing
  • Testicular Ultrasound
Treatment
  • Immediate call to urology when suspected
  • Manual detorsion (“Open the Book”)

Prostatitis

History
  • Pelvic pain
  • Pain with sex
  • Urinary symptoms
  • Fevers and chills
Exam
  • Tenderness of the prostate/epididymis/testicle
Testing
  • Urinalysis
  • Generally a clinical diagnosis
Treatment
  • Commonly sexually transmitted in young men
  • Commonly E coli in older men
  • Bactrim or Fluoroquinolones

PID and Ovarian Torsion

Women have two additional diseases that must be added to the differential diagnosis of their abdominal pain. PID and ovarian torsion.

Pelvic Inflammatory Disease (and Tube-Ovarian Abscess)

Deep pelvic infections high in the reproductive tract frequently caused by sexually transmitted infection but can be caused by other infections (especially anaerobic infections) as well

History
  • Symptoms
    • Lower Abdominal Pain
    • Fevers
    • Vaginal Symptoms (especially discharge)
  • Red Flags
    • High risk sex
    • Delayed presentations
    • IUD (Don’t need to remove if patient has PID, but needs to be noted)
Exam

It is controversial whether all women with pelvic complaints need a full speculum exam (my opinion is that they don’t and that it almost never changes management)

  • Bimanual Exam
    • Cervical motion tenderness
    • Adnexal/Uterine tenderness
Testing
  • Gonorrhea
  • Chlamydia
  • CBC
  • Ultrasound to evaluate for tubo-ovarian ABSCESS
Treatment

Patients who are septic, unable to keep antibiotics down, getting worse on oral antibiotics, pregnant, immunosuppressed, or with TOA generally get admitted for IV antibiotics.

  • Treat chlamydia
    • Doxycycline
  • Treat gonorrhea
    • Cefoxitin/cefotetan (2nd generation cephalosporins provides better anaerobic coverage than a third generation cephalosporins)
    • Ceftriaxone
  • Treat anaerobes
    • 2nd generation cephalosporin
    • Metronidazole

Ovarian Torsion

Ovary twists on its pedicle and becomes ischemic

NOTE: The ovary actually has a dual arterial blood supply. When the pedicle twists, it’s not the artery is being pinched off that causes ischemia, rather its the venous outflow becoming blocked and resulting in swelling of the ovary and the poor perfusion that results)

History
  • Sudden onset pain
  • Severe pain with vomiting
  • Usually unilateral pain (although 25% have bilateral pain)
Exam
  • Peritonitis in the lower abdomen
  • Large mass or adnexal tenderness on pelvic exam
Testing
  • Pelvic ultrasound (with doppler)
    • Swollen/edematous ovary
    • Large cyst/mass causing the torsion
    • IMPORTANT- You can frequently see normal arterial flow on the doppler (remember DUAL BLOOD SUPPLY)
  • CT scan with NORMAL ovaries 100% negative predictive value for torsion in some studies
Treatment

OBGYN consult for surgery

Urinary Tract Infections

How to Read a Urinalysis
  • Signs of Inflammation
    • Leukocyte Esterace
    • WBCs

Multiple conditions cause inflammation on a urinalysis. Anything that causes nearby inflammation (appendicitis, pelvic infections, diverticulitis) or slows urine output (dehydration, renal disease) can commonly elevate these markers.

  • Signs of bacterial presence (not present in ~25% of proven urinary tract infections!!!)
    • Nitrites
    • Bacteria
Asymptomatic Bacteriuria

Generally should NOT be treated with antibiotics. If you were to randomly sample the population you would find bacteria present in approximately…

  • 5% of young people
  • 20% of old people
  • 50% of patients in long term care
When to Diagnose UTI
  • Dysuria AND urinary frequency WITHOUT vaginal symptoms (+LR 20)
  • Patient self reports that they think their UTI is back (+LR 4)
  • Urinalysis shows BOTH signs of inflammation and bacterial presence
  • Combine pretest suspicion with urinalysis findings using clinical judgement
Indwelling Foley Catheters

All patients with an indwelling foley will have a grossly abnormal urinalysis and appearance of urine at baseline. The urinalysis is useless and diagnosis can only be made by clinical judgement

Geriatric Patients

Geriatric patients have minimal symptoms regardless of diagnosis. They can have UTI’s with minimal symptoms. However they can also have appendicitis or kidney stones with minimal symptoms (and asymptomatic bacteriuria at baseline). BE CAREFUL.
