Intralesional immunotherapy for pediatric warts: A review.

Cutaneous warts are a common pediatric complaint with modest response to first-line treatments. Warts are a manifestation of human papillomavirus (HPV) infection and are cleared by cell-mediated immunity (CMI). Intralesional immunotherapy treatments have been studied as alternative therapies, particularly for recalcitrant or multiple warts, including Candida antigen, mumps antigen, the combined measles, mumps, and rubella (MMR) vaccine, tuberculin purified protein derivative (PPD), and bacille Calmette-Guerin (BCG) vaccine. These treatments are thought to increase HPV recognition by stimulating CMI. In this review, we evaluate and compare the efficacy and adverse effects of intralesional immunotherapy in the treatment of pediatric warts. Articles met inclusion criteria if they specifically evaluated the effects of intralesional immunotherapy (candida, MMR, tuberculin PPD, or BCG) as treatment for cutaneous warts in a pediatric population, and if they quantified treatment effect in a reproducible manner. Twenty-one studies met criteria. Many studies demonstrated complete clearance of injected common warts in pediatric patients with clearance rates ranging from 23.3% to 95.2%. Distant wart resolution was common. Intralesional immunotherapy is a promising treatment option for cutaneous warts in children.

Topical ketoconazole for the treatment of androgenetic alopecia: A systematic review.

Androgenetic alopecia (AGA) is common and associated with significant psychosocial distress. Treatment options are needed for patients that do not adequately respond to first line treatments of finasteride or minoxidil. Topical ketoconazole has been proposed as a promising treatment. The goal of this systematic review was to evaluate the efficacy of topical ketoconazole in the treatment of AGA. A systematic literature search was conducted within the MEDLINE database using the key terms "ketoconazole" and "alopecia." Forty-seven papers were screened for inclusion, of which nine were assessed for eligibility. Seven articles were included in the qualitative synthesis, including two animal studies (total of 40 participants) and five human studies (total of 318 participants). Murine studies demonstrated a significant increase in mean ratio of hair regrowth to denuded area in the ketoconazole treatment groups compared to controls. Human studies reported increased hair shaft diameter following ketoconazole use. One study reported a significant increase in pilary index (percent anagen phase × diameter) following treatment. Studies also demonstrated clinical improvement of AGA based on photographic assessment and subjective evaluation. Topical ketoconazole is a promising adjunctive or alternative therapy in the treatment of AGA. Randomized controlled trials are needed.

Intramuscular hemorrhage and fluid extravasation into the anterior compartment secondary to intraosseous resuscitation, the "Nicked-Cortex" sign.

Intraosseous needle access is a reliable method of vascular access used for rapid fluid resuscitation and delivery of medications in certain emergent settings. Fluid extravasation is a possible complication of intraosseous needle access that can lead to compartment syndrome. To our knowledge, imaging findings resulting from this complication have not been described. In this case report, we demonstrate conventional radiograph, computed tomography, and magnetic resonance image findings due to extravasation of resuscitation fluids following the aberrant insertion of an intraosseous needle in an unstable adult trauma patient. We also describe a new radiographic sign associated with this iatrogenic complication, the "Nicked-Cortex" sign.
