ABSTRACT

Lichen planus pemphigoides (LPP) is a rare blistering disease with features of both lichen planus and bullous pemphigoid. LPP typically appears on the extremities and occasionally involves the oral mucosa. Herein, we describe a case of LPP of the vulva of an 80-year-old woman, an uncommon location for this disease process. This clinical scenario can be confused with a number of similarly appearing entities such as erosive vulvar lichen planus, mucous membrane pemphigoid, and erosive lichen sclerosus et atrophicus. In fact, our patient carried a diagnosis of lichen sclerosus by an outside physician for 2 years prior to being properly diagnosed and treated. A detailed discussion of the epidemiology, clinical, and pathogenesis as well as the histologic and immunofluorescence characteristics of this uncommon diagnosis is presented. Our case emphasizes the necessity of microscopic analysis to differentiate lookalike disease states when making a diagnosis and choosing the correct therapeutics.

ABSTRACT

AIM: Surgery residents are required to become proficient in colonoscopy before completing training. The aim of this study was to evaluate the responsiveness of surgery interns to simulated colonoscopy training. METHOD: Interns, defined as postgraduate year 1 residents without exposure to endoscopy, underwent training in a physical model including colonoscopy, synthetic anatomy trays with luminal tattoos and a hybrid simulator. After baseline testing and mentored training, final testing was performed using five predetermined proficiency criteria. Content-valid metrics defined by the extent of departure from clinical reality were evaluated by two blinded assessors. Responsiveness was defined as change in performance over time and assessed comparing baseline testing with nonmentored final testing. RESULTS: Twelve interns (eight male, mean age 26, 80% right-handed) performed 48 colonoscopies each over 1 year. Improvement was seen in the overall procedure time (24 min 46 s vs 20 min 54 s; P = 0.03), passing the splenic flexure (20 min 33 s vs 10 min 45 s; P = 0.007), passing the hepatic flexure (23 min 31 s vs 12 min 45 s; P = 0.003), caecal intubation time (23 min 38 s vs 13 min 26 s; P = 0.008), the duration of loss of view of the lumen (75% vs 8.3%; P = 0.023), incomplete colonoscopy (100% vs 33.3%; P = 0.042), colonoscope withdrawal < 6 min (16.7% vs 8.3%; P = 0.052). Tattoo identification time (9 min 16 s vs 12 min 25 s; P = 0.50), colon looped time (2 min 12 s vs 1 min 45 s; P = 0.50) and rate of colon perforation (8.3% vs 8.3%; P = 1) remained unchanged. Interrater reliability was 1.0 for all measures. CONCLUSION: Simulated colonoscopy training in a low-cost physical model improved the performance of surgery interns with decreased procedure time, increased rates of complete colonoscopy and appropriate scope withdrawal.
