Crowd-Sourced Assessment of Surgical Skills of Urology Resident Applicants: Four-Year Experience.

OBJECTIVE: To determine a) if surgical skills among urology resident applicants could be reliably assessed via crowdsourcing and b) to what extent surgical skills testing impacts resident selection. DESIGN: Interviewees completed the following surgical skills tasks during their interview day: open knot tying (OKT), laparoscopic peg transfer (LPT), and robotic suturing (RS). Urology faculty and crowd-workers evaluated each applicant's video-recorded performance using validated scoring and were assessed for agreement using Cronbach's alpha. Applicants' USMLE scores, interview scores, and Jefferson Scale of Physician Empathy (JSPE-S) scores were assessed for correlation with skills testing scores and match rank. Additionally, a survey was distributed to interviewees assessing match outcomes. SETTING: University of California Irvine Department of Urology, Surgical Skills Laboratory PARTICIPANTS: All 94 urology residency interviewees at the University of California Irvine Department of Urology from 2015-2018 were invited to complete the three surgical skills tasks on their interview day. RESULTS: Survey responses were received from all 94 interviewees (100%). Crowd and expert agreement was good (α=0.88), fair (α=0.67), and poor (α=0.32) for LPT, RS, and OKT scores, respectively. The skills testing scores did not correlate with match rank, USMLE score, or JSPE-S score. On multivariate analysis, only interview score (r= -0.723; p<0.001) and faculty LPT score (r=-0.262; p=0.001) were significant predictors of match rank. Interviewees who reported matching into a top 3 residency choice had significantly higher faculty LPT scores than those who did not (11.9 vs. 9.7, p=0.03). CONCLUSIONS: Surgical skills overall did not significantly impact match rank. Expert assessment of laparoscopic peg transfer skills and interview performance among urology resident applicants correlated with match rank.

Auricular Hemosiderosis in a Diabetic Patient.

A 74-year-old Caucasian man with poorly controlled diabetes and hypertension was seen in the dermatology clinic for treatment of a nodular basal cell carcinoma on his right temple. He had poorly controlled diabetes for decades and had been insulin dependent for 20 to 25 years. He had not been on any anticoagulation therapy in the past or present and had no history of a hematologic disorder. He was retired and did woodworking as a hobby. During a routine presurgical head and neck skin examination, he was noted to have macular bluegray dyspigmentation of the central portion of the anterior portion of his ear lobes, bilaterally (Figure 1). He had first noticed this color change approximately 2 years ago and thought the pigmentation was darkening. It was not symptomatic. A punch biopsy was obtained.

The Association of Mammographic Density and Molecular Breast Cancer Subtype.

Background: Mammographic density (MD) is associated with increased breast cancer risk, yet limited data exist on an association between MD and breast cancer molecular subtypes.Methods: Women ages 18 years and older with breast cancer and available mammograms between 2003 and 2012 were enrolled in a larger study on MD. MD was classified by the Breast Imaging Reporting and Data System (BI-RADS) classification and by volumetric breast percent density (Volpara Solutions). Subtype was assigned by hormone receptor status, tumor grade, and mitotic score (MS). Subtypes included: Luminal-A (ER/PR+ and grade = 1; ER/PR+ and grade = 2 and MS = 1; ER+/PR- and grade = 1; n = 233); Luminal-B (ER+ and grade = 3 or MS = 3; ER+/PR- and grade = 2; ER/PR+ and grade = 2 and MS = 2; n = 79); Her-2-neu+ (H2P; n = 59); triple-negative (ER/PR-, Her-2-; n = 86). Precancer factors including age, race, body mass index (kg/m2), family history of breast cancer, and history of lobular carcinoma in situ were analyzed.Results: A total of 604 patients had invasive cancer; 457 had sufficient information for analysis. Women with H2P tumors were younger (P = 0.011) and had the highest volumetric percent density (P = 0.002) among subgroups. Multinomial logistic regression (LA = reference) demonstrated that although quantitative MD does not significantly differentiate between all subtypes (P = 0.123), the association between MD and H2P tumors is significant (OR = 1.06; confidence interval, 1.01-1.12). This association was not seen using BI-RADS classification in bivariable analysis but was statistically significant (P = 0.047) when controlling for other precancer factors.Conclusions: Increased MD is more strongly associated with H2P tumors when compared with LA.Impact: Delineating risk factors specific to breast cancer subtype may promote development of individualized risk prediction models and screening strategies.

Hemophagocytic Lymphohistiocytosis in a Newborn Presenting as "Blueberry Muffin Baby".

Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening hyperinflammatory syndrome characterized by uncontrolled activation and proliferation of proinflammatory cytokines. Initial presentation commonly includes fever, hepatosplenomegaly, and pancytopenia; 6 to 65% of cases also have a concurrent cutaneous eruption. We present the case of a 6-day-old premature infant boy with congenital severe thrombocytopenia, anemia, and hepatosplenomegaly who presented with several cutaneous violaceous papules and nodules and was found to have HLH.

Bleomycin-induced flagellate hyperpigmentation.

A 27-year old male with Hodgkin's lymphoma was treated with combined chemotherapy that included bleomycin. He presented with pruritic erythematous, edematous linear lesions and was diagnosed to have flagellate hyperpigmentation, a rare side effect of bleomycin chemotherapy.

Hair Follicle Nevus Located on the Chin of an Infant: Case Report and Review of Literature.

Hair follicle nevi are rare, benign, congenital hamartomas that usually occur in the distribution of the first brachial arch. Histopathologically, the distinction between hair follicle nevus, trichofolliculoma, and accessory tragus has recently come into question, and it may be that they are all on a spectrum of the same condition. We report the case of a 7-day-old boy who presented with a "tag"-like lesion on his midline chin that had been present since birth. Biopsy of the lesion proved it to be a hair follicle nevus.

Does Mammographic Density have an Impact on the Margin Re-excision Rate After Breast-Conserving Surgery?

BACKGROUND: Limited and conflicting data exist on an association between mammographic density (MD) and re-excision rates after breast-conserving surgery (BCS). Additionally, the correlation of MD with resection of unnecessary margins during initial BCS is unknown. METHODS: All women with a diagnosis of breast cancer from 2003 to 2012 and enrolled in a larger study on MD were evaluated. Operative and pathology reports were reviewed to determine margin resection and involvement. Mammographic density was determined both by breast imaging-reporting and data system (BI-RADS) classification and by an automated software program (Volpara Solutions). Additional margins were deemed unnecessary if the lumpectomy specimen margin was free of invasive tumor [≥2 mm for ductal carcinoma in situ (DCIS)] or if further re-excision was needed. RESULTS: Of 655 patients, 398 (60.8%) had BCS, whereas 226 (34.5%) underwent initial mastectomy. The women with denser breasts (BI-RADS 3 or 4) underwent initial mastectomy more frequently than the women with less dense breasts (40.0 vs. 30.5%, respectively; p = 0.0118). Of the patients with BCS, 166 (41.7%) required separate re-excision. Additional margins were taken during BCS in 192 (48.2%) patients, with 151 (78.6%) proving to be unnecessary. In the bivariable analysis, the patients with denser breasts according to BI-RADS classification and volumetric density showed a trend toward requiring more frequent re-excision, but this association was not seen in the multivariable analysis. The rate of unnecessary margins did not differ by breast density. In the multivariate analysis, the re-excision rates increased with DCIS (p < 0.0003) and decreased with resection of additional margins (p = 0.0043). CONCLUSIONS: Mammographic density is not associated with an increased need for re-excision or resection of unnecessary margins at initial BCS.

Nephrogenic Systemic Fibrosis Manifesting a Decade After Exposure to Gadolinium.

IMPORTANCE: Nephrogenic systemic fibrosis (NSF) is a fibrosing skin disorder that develops in patients with kidney failure and has been linked to exposure to gadolinium-containing contrast agents. The time between exposure to gadolinium and the initial presentation of NSF is typically weeks to months but has been documented to be as long as 3½ years. We report a case of NSF developing 10 years after exposure to gadolinium. OBSERVATIONS: A long-term hemodialysis patient was exposed to gadolinium several times between 1998 and 2004 during magnetic resonance angiography of his abdominal vessels and arteriovenous fistula. In 2014, he was seen at our clinic with new dermal papules and plaques. Biopsy of affected skin showed thickening of collagen, CD34+ spindle cells, and increased mucin in the dermis, supporting the diagnosis of NSF. CONCLUSIONS AND RELEVANCE: The clinical history and histopathological features of this case support the diagnosis of NSF 10 years after exposure to gadolinium. Although the use of gadolinium contrast agents in patients with kidney failure has markedly decreased, patients with exposure to gadolinium years to decades previously may manifest the disease.
