Q

You see vulvar skin changes suggestive of lichen sclerosis, but it is not responding to standard treatment. you elect to perform a bx.

describe the key areas you would target.

A

sclerotic lesions or ulcerative areas, it is preferable to biopsy the edge of the lesion including a border with normal skin

when sampling hyperpigmented areas, biopsy of the thickest region is recommended

urethral infection at the time of surgery difficult dissection excessive suture line tension
37
How do you counsel patients regarding rUTI treatment?
abx vs non-abx treatment 1. Cranberry-lots of variability in the cranberry amounts so it's hard to replicate the studies. 2. 1.5L of water 3. vaginal estrogen, even a small amount for premenopausal patient on OCPs

39
risk factors for rUTI in premenopausal patients
spermicide low dose OCPs can create mild atrophy
40
what is the evidence regarding D-mannose for UTI?
