How do you approach the management of persistent hyperphosphatemia in ESKD patients who are non-adherent to phosphate binders?
This is not easy. The first thing I usually do is try and find out why they are non-adherent. Is it due to side effects, cost, etc? Are there social reasons? For example, are they "embarrassed" to take binders if they are out eating with friends? Often, I find that I need to switch binders to see if...
What is the current recommendation for air travel after a primary spontaneous pneumothorax?
General guidelines including the British Thoracic Society recommend delaying air travel for at least 2 weeks following the radiographic resolution of a pneumothorax. However, recent studies have challenged this conservative approach. A study by Majercik et al., PMID 25494425 demonstrated that patien...
What are your management strategies for patients with recurrent nephrolithiasis and hypercalciuria who develop hypercalcemia after thiazide initiation?
My first concern is why. The thiazide may have unmasked primary hyperparathyroidism. I would get a PTH level plus serum phosphorus and vitamin D with a concurrent serum calcium to see if they are concordant. If not, it’s time to image the parathyroids. If no evidence of hyperparathyroidism, and hype...
Do you utilize urinary leukotrienes as a marker for initiation of montelukast?
No, I don’t. It is not readily available clinically and has not been shown to be predictive of response.
Do you recommend avoidance of vaginal estrogen in patients with SLE?
It depends on the age. The SELENA study demonstrated that BCPs in premenopausal women did not lead to flares or increased disease activity though the risk of increased clotting is an issue for APL+ folks. Post-menopausal women treated with HRT had an increase in mild flares compared to those not on ...
In your practice, when do you opt to treat unilateral primary hyperaldosteronism medically rather than surgically?
There should be a good reason for not pursuing surgery in a patient with unilateral primary aldosteronism. The surgery is more cost-effective. Some but not all data suggest a faster decrease in cardiovascular morbidity, a lower risk of atrial fibrillation, arterial stiffness, left ventricular mass, ...
Do you prefer still over carbonated water for your patients with recurrent nephrolithiasis who have chronically low urine volumes?
My main concern is hydration. Stone formers tend to be un-thirsty folks, and it is hard to get them to drink anything, let alone my minimum of 2L daily. Generally I recommend plain water; old research found no difference between hard and soft water. To the extent that carbonated water alkalinizes u...
Do you recommend daily topical exit site antibiotic use for patients with a peritoneal dialysis catheter that is only currently being accessed for once weekly flushes?
No. When PD catheters are being accessed only once weekly for flushes, we keep the exit site under a sterile dressing with a chlorhexidine-gluconate-impregnated disc surrounding the exit site. The catheter is accessed only by the PD nurse at the time of flushing, and we do not have the patient perfo...
How do you counsel and manage patients who meet criteria for sleep apnea based on 3% but not 4% desaturation?
It depends on the patient's symptoms. If they have symptoms attributable to sleep apnea then I tell them they have sleep apnea. If they don't have symptoms then I don't diagnose them with sleep apnea. If the patient has an insurance plan that only accepts 4% desaturations and yet they clearly have s...
Do you transition patients with recurrent nephrolithiasis and hypercalciuria off of hydrochlorothiazide in favor of an alternative thiazide diuretic?
No. Assuming the patient tolerates HCTZ well, and it is effective in lowering hypercalciuria, I continue it. Most of the thiazide research has been done using this agent. Stephen B. Erickson, MD
