RESUMEN
PURPOSE: Late alopecia, defined as incomplete hair regrowth > 6 months following cytotoxic chemotherapy or > 6 months from initiation of endocrine therapy, negatively impacts quality of life and may affect dose intensity of adjuvant therapy. This study investigates the effect of oral minoxidil in women with chemotherapy and/or endocrine therapy-induced late alopecia. METHODS: The rate of clinical response was assessed by standardized photography and quantitated with trichoscopy. RESULTS: Two hundred and sixteen patients (mean age 57.8 ± 13.7) were included. The most common cancer diagnosis was breast, in 170 patients (79.1%). Alopecia developed after chemotherapy in 31 (14.4%) patients, endocrine monotherapy in 65 (30.1%) patients, and chemotherapy followed by endocrine therapy in 120 (55.6%) patients. In 119 patients, standardized photography assessments were used to determine clinical change in alopecia after a median of 105 (IQR = 70) days on oral minoxidil and revealed improvement in 88 (74%) patients. Forty-two patients received quantitative trichoscopic assessments at baseline and at follow-up after a median of 91 (IQR = 126) days on oral minoxidil. Patients had clinically and statistically significant increases in frontal hair shaft density (from 124.2 hairs/cm2 at initial to 153.2 hairs/cm2 at follow-up assessment, p = 0.008) and occipital shaft density (from 100.3 hairs/cm2 at initial to 123.5 hairs/cm2 at follow-up assessment. p = 0.004). No patients discontinued oral minoxidil due to adverse events. CONCLUSIONS: Overall, oral minoxidil was well tolerated by patients and may benefit both frontal and occipital late alopecia in cancer survivors treated with cytotoxic and/or endocrine therapy by increasing hair shaft and follicle density.
RESUMEN
PURPOSE: Patients with prostate cancer (PCa) treated with apalutamide frequently develop rash. We aim to characterize apalutamide-related dermatological adverse events (dAEs) and management. MATERIALS AND METHODS: We assessed 303 patients with PCa treated with apalutamide. DAE frequency and time to onset were calculated and clinicopathological features and management described. Associations between dAE occurrence and clinical trial participation, as well as abiraterone/prednisone exposure were detected using logistic regression models. RESULTS: Seventy-one (23.4%) patients had all-grade dAE occurring at a median of 77 (IQR: 30-135) days post-exposure. Twenty (6.6%) dAE-related therapy interruptions included: 8 (2.6%) with dose maintained on rechallenge, 7 (2.3%) with dose reduction and 5 (1.7%) with discontinuation. Common dAEs were maculopapular rashes (33.8%) and xerosis (32.4%). Seven (77.8%) of 9 histological analyses of skin biopsies supported a drug reaction. No significant differences in laboratory hematological, hepatic and renal function were detected between dAE and no dAE cohorts. Most treated grade 1/2 dAEs (29, 40.8%) required topical steroids (14, 19.7%); few required oral steroids (3, 4.2%) ± oral antihistamines. Most grade 3 dAEs (8, 11.3%) required oral/topical steroids (5, 7.0%); few required topical steroids (3, 4.2%) ± oral antihistamines. Clinical trial patients (180, 59.4%) were more likely to report dAEs than those in the off-trial setting (OR=5.1 [95% CI 2.55-10.12]; p <0.001). Of clinical trial patients, concomitant abiraterone/prednisone recipients (109 of 180, 60.6%) were more likely to report dAEs (OR=3.1 [95% CI 1.53-6.17]; p=0.002). CONCLUSIONS: Apalutamide-related dAEs are frequent and can be managed with topical ± oral steroids. With expanded approval of apalutamide, dAE identification and management are essential.

Reflectance confocal microscopy (RCM) allows noninvasive, real-time evaluation of the skin at a resolution akin to histopathology (HP), but its application in cutaneous graft-versus-host disease (GVHD) has not been extensively assessed. We describe RCM features of cutaneous GVHD including acute (aGVHD), late acute, chronic (cGVHD; sclerotic and nonsclerotic subtypes), and inactive GVHD and correlate RCM with same-site HP for a subset of patients. Thirty-two adult and pediatric allogeneic hematopoietic cell transplantation (allo-HCT) recipients with cutaneous GVHD received RCM imaging of ≥1 lesions (n = 44), 13 of which necessitated skin biopsy. RCM images were deidentified and assessed by 2 RCM experts blinded to clinical and HP findings to reach a consensus on the features and patterns of the inflammatory dermatoses. Major RCM features (present in ≥65% of lesional sites) and patterns were reported. To determine the correlation between RCM and HP, detection of cellular features and patterns of inflammatory dermatoses were compared using percent agreement and prevalence-adjusted, bias-adjusted kappa estimates. Seven patients with early or late aGVHD (7 lesions) had irregular honeycombing, spongiosis, dermoepidermal junction (DEJ) and dermal inflammation, and melanophages; those with early aGVHD also had hyperkeratosis, dilated vessels, and coarse connective tissue. Both groups had an interface dermatitis pattern. Eighteen patients with nonsclerotic cGVHD (24 lesions) had irregular honeycombing, spongiosis, DEJ and dermal inflammation, dilated vessels, coarse connective tissue, and interface and spongiotic dermatitis patterns. Three sclerotic patients with cGVHD (7 lesions) had irregular honeycombing, DEJ and dermal inflammation with an interface dermatitis pattern. Four patients with inactive GVHD (6 lesions) showed minimal inflammation. RCM and HP had similar detection rates for 6 of 13 features and overall patterns important for diagnosis in 2 patients with late aGVHD (2 lesions; 15%) and 10 with nonsclerotic cGVHD (11 lesions; 85%) necessitating skin biopsy. RCM can detect features commonly reported in cutaneous GVHD and is comparable to HP. Additional characterization of cutaneous GVHD by RCM may enable future use in diagnosing, monitoring, or predicting disease in real time.

OBJECTIVES: Most children in the United States who visit the emergency department (ED) with fever have minor illnesses not requiring treatment or hospitalization. However, when a child has recently immigrated or traveled abroad, internationally acquired severe systemic infections (ISSIs) must be considered. We sought to describe children who have traveled internationally and present to the ED with a complaint of fever and to determine risk factors associated with ISSIs in these patients. METHODS: We conducted a retrospective study of children younger than 18 years who presented to 2 pediatric EDs in Bronx, NY (June 2007 to May 2017). Patients were included if they had both fever within 24 hours and international travel within 30 days. We compared groups using bivariate analyses and created a prediction model for ISSIs using multivariable logistic regression. RESULTS: Of the 353 children included, 44 (12%) had ISSI: 25 (57%), malaria; 6 (14%), dengue; and 13 (30%), bacteremia. Eight (18%) of those with ISSI presented with fever to another medical provider in the week prior but did not receive bloodwork. Four variables were independently associated with ISSIs: headache (odds ratio [OR], 21.7; 95% confidence interval [CI], 6.8-69.3), travel to Africa or Asia (OR, 18.8; 95% CI, 4.8-73.2), platelets of 150,000/µL or less (OR, 15.1; 95% CI, 4.7-48.6), and alanine aminotransferase level of 30 IU/L or greater (OR, 8.9; 95% CI, 3.1-25.3). CONCLUSIONS: Children who travel internationally and present with fever upon return are at substantial risk for developing ISSIs. The diagnosis of ISSIs is often overlooked, but certain risk factors have the potential to aid clinicians.

RESUMEN
PURPOSE: Recruitment of participants from diverse backgrounds is crucial to the generalizability of genetic research, but has proven challenging. We retrospectively evaluated recruitment methods used for a study on return of genetic results. METHODS: The costs of study design, development, and participant enrollment were calculated, and the characteristics of the participants enrolled through the seven recruitment methods were examined. RESULTS: A total of 1118 participants provided consent, a blood sample, and questionnaire data. The estimated cost across recruitment methods ranged from $579 to $1666 per participant and required a large recruitment team. Recruitment methods using flyers and staff networks were the most cost-efficient and resulted in the highest completion rate. Targeted sampling that emphasized the importance of Latino/a participation, utilization of translated materials, and in-person recruitments contributed to enrolling a demographically diverse sample. CONCLUSIONS: Although all methods were deployed in the same hospital or neighborhood and shared the same staff, each recruitment method was different in terms of cost and characteristics of the enrolled participants, suggesting the importance of carefully choosing the recruitment methods based on the desired composition of the final study sample. This analysis provides information about the effectiveness and cost of different methods to recruit adults for genetic research.

BACKGROUND: Exome sequencing is emerging as a first-line diagnostic method in some clinical disciplines, but its usefulness has yet to be examined for most constitutional disorders in adults, including chronic kidney disease, which affects more than 1 in 10 persons globally. METHODS: We conducted exome sequencing and diagnostic analysis in two cohorts totaling 3315 patients with chronic kidney disease. We assessed the diagnostic yield and, among the patients for whom detailed clinical data were available, the clinical implications of diagnostic and other medically relevant findings. RESULTS: In all, 3037 patients (91.6%) were over 21 years of age, and 1179 (35.6%) were of self-identified non-European ancestry. We detected diagnostic variants in 307 of the 3315 patients (9.3%), encompassing 66 different monogenic disorders. Of the disorders detected, 39 (59%) were found in only a single patient. Diagnostic variants were detected across all clinically defined categories, including congenital or cystic renal disease (127 of 531 patients [23.9%]) and nephropathy of unknown origin (48 of 281 patients [17.1%]). Of the 2187 patients assessed, 34 (1.6%) had genetic findings for medically actionable disorders that, although unrelated to their nephropathy, would also lead to subspecialty referral and inform renal management. CONCLUSIONS: Exome sequencing in a combined cohort of more than 3000 patients with chronic kidney disease yielded a genetic diagnosis in just under 10% of cases.

Alopecia areata (AA) is a common autoimmune disease and it is challenging to predict which patients will have severe disease. The purpose of this retrospective study was to identify comorbidities in children enrolled in the National Alopecia Areata Registry. Atopic dermatitis was more common in patients with severe AA than in those with mild disease. The most common autoimmune comorbidities were vitiligo, psoriasis, thyroid disease, and juvenile idiopathic arthritis.
