BACKGROUND AND OBJECTIVES: Propranolol is first-line therapy for problematic infantile hemangiomas (IHs). Rebound growth after propranolol discontinuation is noted in 19% to 25% of patients. Predictive factors for rebound are not completely understood and may alter the management approach. The goal of the study was to describe a cohort of patients with IHs treated with propranolol and to identify predictors for rebound growth.

METHODS: A multicenter retrospective cohort study was conducted in patients with IHs treated with propranolol. Patient demographic characteristics, IH characteristics, and specifics of propranolol therapy were obtained. Episodes of rebound growth were recorded. Patients' responses to propranolol …

Endothelial To Mesenchymal Transition (Endomt) In The Pathogenesis Of Systemic Sclerosis-Associated Pulmonary Fibrosis And Pulmonary Arterial Hypertension. Myth Or Reality?, Sergio A. Jimenez, Sonsoles Piera-Velazquez

Department of Dermatology and Cutaneous Biology Faculty Papers

Systemic Sclerosis (SSc) is a systemic autoimmune disease characterized by progressive fibrosis of skin and multiple internal organs and severe functional and structural microvascular alterations. SSc is considered to be the prototypic systemic fibrotic disorder. Despite currently available therapeutic approaches SSc has a high mortality rate owing to the development of SSc-associated interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH), complications that have emerged as the most frequent causes of disability and mortality in SSc. The pathogenesis of the fibrotic process in SSc is complex and despite extensive investigation the exact mechanisms have remained elusive. Myofibroblasts are the cells …

Journal of Mind and Medical Sciences

Cutis verticis gyrata is a rare disease characterized by convoluted folds and deep furrows of the scalp, resembling the gyri and sulci of the cerebral cortex. Basal cell carcinoma is the most frequent cancer in Caucasians, patients frequently presenting multiple tumors. We report the case of a 62 year old male, Caucasian patient, from the urban area, who addressed the dermatology department of our hospital for multiple tumors located on the face and upper trunk. A careful examination revealed cerebriform folding of the skin of the scalp. Neurological, psychological, ophthalmological and endocrine disorders were disproven. The patient was diagnosed with …

Ectopic Mineralization Of Cartilage And Collagen-Rich Tendons And Ligaments In Enpp1asj-2j Mice., Jieyu Zhang, Nathaniel A Dyment, David W Rowe, Sarah Y Siu, John P Sundberg, Jouni Uitto, Qiaoli Li

Department of Dermatology and Cutaneous Biology Faculty Papers

Generalized arterial calcification of infancy (GACI), an autosomal recessive disorder caused by mutations in the ENPP1 gene, manifests with extensive mineralization of the cardiovascular system. A spontaneous asj-2J mutant mouse has been characterized as a model for GACI. Previous studies focused on phenotypic characterization of skin and vascular tissues. This study further examined the ectopic mineralization phenotype of cartilage, collagen-rich tendons and ligaments in this mouse model. The mice were placed on either control diet or the "acceleration diet" for up to 12 weeks of age. Soft connective tissues, such as ear (elastic cartilage) and trachea (hyaline cartilage), were processed …

Pressure To Publish For Residency Applicants In Dermatology, Jordan V. Wang, Matthew S. Keller

Department of Dermatology and Cutaneous Biology Faculty Papers

As it grows increasingly difficult to match into a dermatology residency program each year, there is a widening gap in research accomplishments between those who have and have not matched successfully. Applicants should be aware of the current trends in order to maximize their chances of matching. Such research inequality may subsequently lead to increases in the pressure to publish and the incidence of academic misrepresentation. Academic dermatology programs should be aware of these issues in order to help their students successfully match and exercise caution when reviewing the curricula vitae of applicants. We believe that student mentors in dermatology …

C-Src/Cav1-Dependent Activation Of The Egfr By Dsg2., Andrew M. Overmiller, Kathleen P. Mcguinn, Brett J. Roberts, Felicia Cooper, Donna M. Brennan-Crispi, Takahiro Deguchi, Sirkku Peltonen, James K. Wahl, Mỹ G. Mahoney

Department of Dermatology and Cutaneous Biology Faculty Papers

The desmosomal cadherin, desmoglein 2 (Dsg2), is deregulated in a variety of human cancers including those of the skin. When ectopically expressed in the epidermis of transgenic mice, Dsg2 activates multiple mitogenic signaling pathways and increases susceptibility to tumorigenesis. However, the molecular mechanism responsible for Dsg2-mediated cellular signaling is poorly understood. Here we show overexpression as well as co-localization of Dsg2 and EGFR in cutaneous SCCs in vivo. Using HaCaT keratinocytes, knockdown of Dsg2 decreases EGFR expression and abrogates the activation of EGFR, c-Src and Stat3, but not Erk1/2 or Akt, in response to EGF ligand stimulation. To determine whether …

Theory-Driven Longitudinal Study Exploring Indoor Tanning Initiation In Teens Using A Person-Centered Approach, Joel J. Hillhouse, Rob Turrisi, Michael J. Cleveland, Nichole M. Scaglione, Katie Baker, L. Carter Florence

ETSU Faculty Works

Background

Younger indoor tanning initiation leads to greater melanoma risk due to more frequent and persistent behavior. Despite this, there are no published studies exploring the predictors of indoor tanning initiation in teen populations.

Purpose

This longitudinal study uses latent profile analysis to examine indoor tanning initiation in indoor tanning risk subgroups from a national sample of female adolescents.

Methods

Latent profile analysis used indoor tanning beliefs and perceptions to identify indoor tanning initiation risk subgroups. The teens in each subgroup were reassessed on indoor tanning initiation after a year.

Results

Three subgroups were identified: a low risk, anti-tanning subgroup …

Case Report: Recurrent Staphylococcal Scalded Skin Syndrome In Healthy Term Neonate Despite Full Course Of Antibiotic Therapy, Indira Bhavsar, Rebecca Hayes, Amy Vaughan

Staphylococcal scalded skin syndrome (SSSS) describes a blistering skin infection caused by the exfoliative toxin in the bacterium Staphylococcus aureus. It more commonly affects the infant population and is characterized by large blistering bullae that rupture upon application of pressure.

Case description

We describe a case of recurrent SSSS in a healthy term neonate who initially presented with a perioral rash on day of life (DOL) 11 that quickly became vesicular with new lesions on the sternum and extremities. The patient’s rash began to resolve upon administration of culture-specific IV antibiotics. She was appropriately treated with a 14-day …

Biosimilars: Potential Implications For Clinicians, Misty G. Eleryan, Sophia Akhiyat, Monica Rengifo-Pardo, Alison Ehrlich

Dermatology Faculty Publications

With the expiration of patent protection for several biologics looming, the production of highly similar therapeutic agents has begun to emerge on the pharmaceutical market. These alternative drugs are referred to as biosimilars. Many anticipate that the introduction of these agents will result in a reduction in health care costs, which may create a more affordable biopharmaceutical market and also improve patient access. In contrast to generics, which are exact copies of their original products, biosimilars are not identical to their reference products. Due to concern about the safety and efficacy of biosimilars, separate regulatory approval pathways have been developed …

Regulation Of Uv-Protective Pathways Downstream Of The Melanocortin 1 Receptor In Melanocytes, Erin M. Wolf Horrell

Theses and Dissertations--Physiology

Malignant cutaneous melanoma is the deadliest form of skin cancer, and a majority of melanoma diagnoses are a result of exposure to ultraviolet (UV) radiation. UV radiation causes DNA damage, which if not repaired correctly via nucleotide excision repair (NER) can result in mutations and melanomagenesis. The melanocortin 1 receptor (MC1R) is a G_s protein coupled receptor located on melanocyte plasma membranes and is involved in protecting the skin from UV induced damage. MC1R signaling results in the activation of two protective pathways: 1) induction of eumelanin synthesis downstream of micropthalmia-associated transcription factor (MITF) and 2) acceleration of NER …

A Comparison Of Various Monoclonal Antibodies To The Previous Standard Of Care Chemotherapy In The Treatment Of Advanced-Stage Melanoma, Kevin Verde, Lauren Johnson, Alex Clancy, Ashley Goldberg, Aleia Monden, Priya Philip

Internet Journal of Allied Health Sciences and Practice

In the year 2015, it is estimated that the number of new cases of invasive melanoma will be 42,670 in males and 31,200 in females.¹ Melanoma is treatable with early diagnosis; however, more advanced disease has devastating outcomes. For the past decade, two chemotherapy agents, dacarbazine and temozolomide, have been the treatment of choice for advanced stage III or IV melanoma requiring systemic treatment. Interleukin-2 (IL-2) therapy has been used but with serious side effects. More recently, the focus has shifted to monoclonal antibodies and enzyme inhibitors as the main systemic treatment for advanced cutaneous melanoma. This literature review …

ETSU Faculty Works

Background: Indoor tanning elevates the risk for melanoma, which is now the most common cancer in US women aged 25-29. Public policies restricting access to indoor tanning by minors to reduce melanoma morbidity and mortality in teens are emerging. In the United States, the most common policy restricting indoor tanning in minors involves parents providing either written or in person consent for the minor to purchase a tanning visit. The effectiveness of this policy relies on parents being properly educated about the harms of indoor tanning to their children.

Objective: This randomized controlled trial will test the efficacy …
