Q

24 y/o female presents to urgent care with pain and burning with urination for the past 5 days. She denies any other pain and denies any color or odor change in her urine. She denies any fever, chills, nausea, vomiting, bowel changes or back pain and has been otherwise healthy. She is sexually active 2-3 times per week, with 3 different partners and intermittently uses condoms. 28 day cycle with no changes. Her only med is oral contraception one tablet daily, multivitamin daily and no other OTC’s.

What is the most likely diagnosis?

  • A.Cystitis
  • B.Urethritis
  • C.Pyelonephritis
  • D.Vaginitis
  • E.Papillary necrosis
A

B. Urethritis bc INC risk for STI

  • Cystitis => causes suprapubic/abdominal pain
  • Pyelo => fever, back pain, fatigue

Q

Treatment of GC and Chlamydia

A
  • GC: Azithromycin+ Ceftriaxone
  • Chlamydia: Azithromycin or doxycyline
  • Give single dose if possible, tx contacts, counsel on risk reduction

Q

Treatment of cystitis and pyelonephritis

A
  • Cystitis: Trimethoprim-Sulfamethoxazole
  • Pyelonephritis: Fluorquinolone (levofloxacin)
17
Q

Infectious/non-infectious Prostatitis with or w/o hypertrophy

  • Key sx
  • ABX
A
  • Prostatic, pelvic or perianal area (where I sit down)
  • ABX for 4-6 weeks
18
Q

If pt has

    • STI and hx of dysuria =>
    • Suprapubic pain
    • V painful
    • Perianal pain
A
  1. Urethritis
  2. Cystitis
  3. Renal lithiasis
  4. Prostastitis
19
Q

Pt is sick, fever/chills, positive CVA tenderness

A

Pyelonephrititis (typically d/t ascending UTI infection, so precursors are the same)

20
Q

Pyelonephritis

  • MC cause:
  • ______ develops in 20-30% of cases
  • Instead of ascending spread, can spread _________ via
A
  • E.Coli
  • Bacteremia
  • Hematogenous (candida, salmonella, s. aureus)
21
Q

3 Major Subtypes/Complications of Pyelonephritis

A
  1. Papillary necrosis
  2. Emphysematous pyelonephritis
  3. Xanthogranulomatous pyelonephritis
22
Q

4 Conditions Papillary Necrosis is seen in

A
  1. Obstruction
  2. DB
  3. Sickle cell
  4. Analgesic nephropathy
23
Q

What is Emphysematous Pyelonephritis?

A
  • Gas in nephric/perinephric area that occurs almost EXCLUSIVELY in DIABETIC patients.
24
Q

What is Xanthogranulomatous Pyelonephritis?

A
  • Chronic obstruction/infection that causes suppurative destruction of kidney, forming abscesses.
25
Q

Bacteremia vs sepsis vs septic shock?

A
  1. Bacteremia = + blood culutes
  2. Sepsis (septicemia) = bad host response to infection => acute increase in organ failure
  3. Septic shock = progressive organ failure => increase mortality seen when serum lactate > 2 mmol/L (18 mg/dL)
26
Q

When a patient is under septic shock => _________ is needed to keep MAP > 65mmHg

A

vasopressors, if not responsive to fluid

27
Q

Acute ischemia of major organs occurs when there is a defect in ____________

A

Effective circulating volume

28
Q

Sx of septic shock

A
  1. Fever/hypothermia (infection)
  2. Tachycardia ( <3 response to hypoperfuson and fever)
  3. Hypotension
  4. Decreased O2 to tissue and increase lactic acid
  5. Tachypnea (lungs try to compensate)
  6. Edema
  7. Circulating cytokines => endothelium is damaged (decreaed tone and increased permeability)
29
Q

Non-medication preventive strategies in women

A
  1. Increased fluid intake
  2. pee after sex
  3. showers, not baths
  4. lactobacillus probiotics
  5. cranberry and vit. C
30
Q

Which of the following indicates a diagnosis of sepsis?

  • A.Hyperthermia
  • B.Muddy brown casts
  • C.Hypotension
  • D.Urine culture positive for e. coli
  • E.Pyuria
A

Hypotension** -all others suggest infection, but

  • low blood pressure => organ dysfunction and decreased oxygenation of organs => intermittent confusion
