Acute Genital Ulceration After Severe Acute Respiratory Syndrome Coronavirus 2 Vaccination and Infection.

Reactive, nonsexually related acute genital ulceration, also known as Lipschütz ulcer, is a nonsexually related ulceration involving the vulva, most commonly affecting girls and adolescent women in response to infection. Herein, we describe 3 female patients with acute genital ulceration occurring after severe acute respiratory syndrome coronavirus 2 vaccination or natural infection.

Genital vitiligo in children: Factors associated with generalized, non-segmental vitiligo.

Background/objectives: It remains uncertain as to whether genital vitiligo of childhood is segmental or a forme fruste of non-segmental disease. This type of vitiligo is sometimes termed figure-of-eight disease due to female predominance and perineal and perianal hypopigmentation or depigmentation around two orifices, the anal and vaginal introitus. The objective of this series was to categorize the features of genital-limited vitiligo of childhood including comorbidities, family history, and long-term course.

Association between Eosinophilic Esophagitis and Esophageal Food Impaction in the Pediatric Population.

Objectives (1) To describe the presentation, management, and outcomes associated with pediatric esophageal food impaction (EFI) at a single tertiary care institution. (2) To identify the key clinical features of pediatric EFI that are associated with a diagnosis of eosinophilic esophagitis (EoE). Study Design Case series with chart review.

Vitamin and Mineral Deficiencies in Patients With Telogen Effluvium: A Retrospective Cross-Sectional Study.

Telogen effluvium is one of the most common forms of non-scarring alopecia for which patients present to a dermatologist. It is a challenging disorder to treat and study, primarily owing to its multifactorial etiology which includes both physiologic and non-physiologic factors. Nutritional deficiency has been purported to contribute to hair shedding, and a patient's clinical history usually aids in directing laboratory evaluation.

Predictors of Foreign Body Aspiration in Children.

Objectives: To examine the sensitivity and specificity of history, physical examination, and radiologic studies as predictors of foreign body aspiration in children.

Study Design: Case series with chart review.

Setting: Tertiary care children's hospital.

Diagnosis of Pediatric Foreign Body Ingestion: Clinical Presentation, Physical Examination, and Radiologic Findings.

Objectives: (1) To describe clinical and radiologic findings in patients with esophageal foreign bodies. (2) To examine the sensitivity and specificity of history, physical examination, and radiologic studies in children with suspected foreign body ingestion.

Methods: A retrospective cohort study was performed evaluating all children who underwent esophagoscopy for suspected foreign body ingestion at our institution from 2006 to 2013.

Rats preexposed to MDMA display attenuated responses to its aversive effects in the absence of persistent monoamine depletions.

Rationale: The abuse potential of a given drug may be mediated by both its rewarding and aversive effects, the latter of which are often far less characterized.

Objectives: Using the conditioned taste-aversion (CTA) preparation, the present experiments examined changes in the aversive effects of the commonly used recreational drug MDMA following repeated drug exposures.

Methods: Experiment 1 used three varying doses of MDMA (1.
