Q
Acid-Base Basics
A
acid-base balance is coordinated by lungs and kidneys to keep optimal pH
- goal pH: 7.35-7.45
- lungs regulate pCO2
- kidneys regulate HCO3-
Note: when one system fails, the other tries to compensate to bring back balance
25
acidosis
results when pH is too low (<7.35)
- pCO2 is HIGH (>40)
- HCO3 is LOW (<24)
Note: think of CO2 as Hydrogen
26
alkalosis
results when pH is too high (>7.45)
- HCO3- is HIGH (>24)
- pCO2 is LOW (<40)
27
acid-base question: approach
1. identify if you have an acidic or basic state
- acidic: pH<7.35
- basic: pH>7.35
2. identify if it is metabolic (HCO3-) or respiratory (pCO2) underlying the cause
3. Consider underlying cause and correct
28

low pH, low HCO3-
anion gap > 16
causes: MUDPILERS
```
M: methanol
U: uremia
D: DKA
P: propylene glycol, acetaminophen,

L: lactic acidosis
E: ethanol (due to lactic acidosis), ethylene glycol
R: rhabdomyolysis

- no fever, neg. U/A, positive urine cx, prostatic secretions w/ inc. WBCs
Tx (>50% relapse):
- TMP/SMZ, quinolones x 6-12 WEEKS
- NSAIDs, alpha-blockers, sitz baths
79
nonbacterial prostatitis (CPPS: chronic pelvic pain syndrome): definition, s/sx, dx, tx
sxs of chronic prostatitis w/o infection
s/sx:
- chronic pelvic pain (wax and wane)
- can be inflammatory or non inflammatory
- cause unknown / dx of exclusion
- NO hx of acute bacterial prostatitis
dx:
- no fever, neg. U/A, neg. urine cx, may have WBC in prostatic secretions if inflammatory
tx:
- ABX usually tried but do not help
- alpha blockers, NSAIDs, benzos??
80
testicular carcinoma: risks, population, tumor type, s/sx, dx, tx, prognosis
risks:
- cryptorchidism (40%!)
- FH or personal hx
- males 15-35 y/o (most common neoplasm)
tumor type: most are germ cell tumors (nonseminomas and seninomas)
- bHCG and LDH elevated in both
- AFP elevated in nonseminomas
s/sx:
- PAINLESS testicular mass
- usually does not MET (to lungs and brain if it does)
dx:
- scrotal U/S
- CT (abd, pelvis, chest) and MRI (brain) for mets
tx:
- radical orchiectomy
- radiation w/ seminomas
- no radiation w/ nonseminomas
prognosis: excellent (90-95% cure rate)
81
prostate cancer: risks, tumor type, s/sx, PE, mets
risks: age, AA, FH
tumor type: adenocarcinomas (95%)
s/sx:
- many asymptomatic
- pain, obstructive urinary sxs, erectile dysfunction
PE:
- DRE: indurated, hard prostate gland; may feel nodules
Mets: bone (axial skeleton - low back)
82
Prostate specific antigen (PSA)
Good for staging, trending dx, detecting recurrence
NOT for screening
- only if FH
Not: PSA is reduced by 50% by 5 alpha reductase inhibitors (used to tx BPH)
83
prostate cancer: dx, prognosis, tumor surveillance, tx
Dx: trans-rectal U/S-guided biopsy
Gleason score:
- evaluates tissue sample
- higher score = cells less differentiated/irregular = poorer prognosis
tumor surveillance:
- CT abd and pelvis
- bone scan
- MRI
Tx: many options
- prostatectomy
- radiation
- cryotherapy
- hormone therapy / androgen deprivation (LHRH agonists, antiandrogen meds, orchiectomy)
- chemotherapy (if hormone therapy failed)
84
bladder cancer: risks, s/sx,
risks:
- smoking (#1)
- industrial dyes, solvents
- male, > 40y/o
s/sx:
- PAINLESS hematuria (bladder cancer until proven otherwise)
- may have irritative voiding sxs
dx:
- cystoscopy w/ biopsy
tx: depends on penetration of bladder wall
- Ta, T1: does not invade wall - transurethral resection +/- intravesical chemo
- >T2: invades wall - radical cystectomy + pelvic lymphadenactomy +/- chemo and radiation
85
renal cell carcinoma: risk factors, s/sx, paraneoplastic syndrome, dx, tx
NOT common
Risks:
- smoking, male, obesity, HTN
Note: risk of producing occlusive thrombi in renal vein and IVC!!
s/sx:
- hematuria
- flank pain or mass
20% will have paraneoplastic syndromes (tumor produces ectopic hormones)
- hypercalcemia
- erythrocytosis
- HTN
- anemia
dx:
- imaging: CT w/ eval for mets (CXR, bone scan)
- labs: U/A, studies for paraneoplastic syndromes
tx:
- if localized, radical or partial nephrectomy
- if mets: palliative care
86
Wilms tumor (aka nephroblastoma): definition, population, s/sx, dx, tx, prognosis
cells meant to form kidney fail to develop properly
- peak incidence 2-3 y/o
- 5% childhood cancers
s/sx:
- PALPABLE ABDOMINAL MASS (60%)
- abdominal pain
- hematuria
- N/V, anorexia, fever
Dx:
- imaging
- biopsy is not done b/c could spill tumor cells
tx:
- surgical resection, nephrectomy, chemo, radiation
prognosis: 85% curable
