Ipledge Must Abstain From Abstinence, Kami Lowery, Theodore Rosen, Janet Malek

Faculty, Staff and Students Publications

Isotretinoin has unmatched efficacy in the treatment of acne. However, because isotretinoin is a teratogen that can cause profound birth defects, the iPLEDGE program regulates the drug's distribution in the United States. To minimize fetal exposure to isotretinoin, the program requires that female patients capable of becoming pregnant use two forms of contraception or commit to abstinence while using this therapy. This manuscript argues that iPLEDGE should be revised to remove abstinence as an acceptable contraceptive option in the face of evidence that disputes its efficacy. All patients, regardless of reported sexual activity, should be required to use data-proven contraception. …

Malignant Degeneration Of Spiradenoma Of The Eyebrow, Christopher White, Kristin Witfill, Richard Miller

West Florida Division GME Research Day 2020

Spiradenocarcinoma is a malignancy of eccrine origin, with only 120 reported cases in the literature.¹ Elderly males and females are equally affected.² Benign spiradenomas along with their malignant counterpart are more frequent in patients with Brooke-Spiegler syndrome or familial eccrine spiradenoma, owing to the increased incidence of folliculosebaceous-apocrine tumors seen with these entities.³

Bilateral Sporotrichoid Cutaneous Atypical Mycobacterial Infection Due To Primary Inoculation, Erin Lowe, Alexa Broderick, Richard Miller

West Florida Division GME Research Day 2020

The group of mycobacterial species that excludes Mycobacteria tuberculosis and Mycobacteria leprae is known as nontuberculosis or atypical mycobacteria. Nearly all atypical mycobacteria species can cause cutaneous infection. The diagnosis is challenging as disease may take months to become clinically apparent, morphology is non-specific, routine culture has a low sensitivity, and organisms can be sparse on histopathologic examination. Antibiotic resistance and further complicates management. The Gulf Coast is the highest incidence region of cutaneous atypical mycobacterial infections. Here we present a challenging case of bilateral sporotrichoid atypical mycobacterial infection due to primary inoculation.

Acral lentiginous melanoma (ALM), named for its location and histological growth pattern, is a rare variant of melanoma. ALM presents on palms, soles, or in association with the nail unit.1 While ALM accounts for approximately 5% of melanomas diagnosed each year, it is the most commonly diagnosed subtype of melanoma in non-Caucasian patients.

Hailey-Hailey Disease Successfully Treated With Low-Dose Naltrexone, John Moesch, Richard Miller

West Florida Division GME Research Day 2020

Hailey-Hailey disease (HHD) is an uncommon autosomal dominant disorder resulting from a mutation in the ATP2C1 gene resulting in dysfunction of the Golgi apparatus calcium-associated ATPase, thus interfering with intercellular calcium signaling.

HHD presents clinically as flaccid blisters and erosions in intertriginous areas, especially the axillae and groin.

The major histologic finding is acantholysis throughout the spinous layer of the epidermis, commonly referred to as a “dilapidated brick wall” appearance.

The initial lesions and associated symptoms usually develop during the second or third decade of life.

Complications of HHD include infections (bacterial, fungal, and viral), and malignant transformation (cutaneous squamous …

A Rare Case Of Primary Cutaneous Mucoepidermoid Carcinoma, Hassie Cooper, Maheera Farsi, Richard Miller, Pay Kamrani, Dudith Pierre Victor

West Florida Division GME Research Day 2020

Mucoepidermoid carcinoma (MEC) is a well-documented malignant tumor commonly found in the salivary glands. Cutaneous involvement is very rare, especially when presenting as a primary cutaneous neoplasm. Gallagher first described primary cutaneous MEC in 1959 and since then, to the best of our knowledge, there have been approximately 20 reports published in the literature. Here we present a very rare case of primary cutaneous mucoepidermoid carcinoma.

Functional Analysis Of A Critical Glycine (Glycine 12) In Beta-Type Connexins Of Human Skin, Rasheed Bailey

Biology Theses

At least five beta-type connexins are expressed in various layers of the skin (Cx26, Cx30, Cx30.3, Cx31, and Cx32) and all include a glycine residue at position 12. Glycine12 (G12) is located about halfway through the cytoplasmic amino terminus and has been the focus of several studies related to connexin diseases and gap junction channel structure. The importance of this residue is evident in the severity and diversity of diseases associated with amino acid substitutions at G12 including hereditary forms of skin disease, deafness and neuropathy. This study uses bioinformatic analysis in combination with mutational analysis and electrophysiology to better …

Covid-19 Pandemic & Skin Care Guidelines For Health Care Professionals, Sadia Masood, Saadia Tabassum, Shaheen Naveed, Palwasha Jalil

Section of Internal Medicine

The Novel corona virus is bringing multiple challenges for health care professionals. Skin is the biggest organ and the first line of defense against different infections and external factors. Being the front line warriors, health care professionals are susceptible to various skin conditions due to prolonged use of personal protective equipment. These adverse skin conditions are redness, irritation, itching, contact dermatitis, and aggravation of underlying skin conditions like seborrheic dermatitis and acne vulgaris. In the current global situation, the potential incidence of such adverse dermatological effects does not in any manner cause the HCPs to deviate from the strict specific …

Post-Surgical Pyoderma Gangrenosum After Breast Surgery: A Case Series, Jahan Tajran, Daniella Anderson, Arif Chaudhry, Dennis Hammond

Medical Student Research Symposium

Background:

Pyoderma gangrenosum (PG) is a rare inflammatory cutaneous disorder that is thought to be due to innate immune system dysfunction, specifically of neutrophils. PG has been well documented in patients with autoimmune disorders like Ulcerative Colitis and Rheumatoid Arthritis. PG can also present in surgical patients, imitating a potential wound infection and necrotizing fasciitis. Although PG is a diagnosis of exclusion, prompt recognition is essential to attaining desired aesthetic outcomes, especially with breast involvement. We present a case series of four patients who developed PG following breast surgery. We analyze each patient’s medical history, symptoms, wound progression and management …

Use Of Biologics In Pityriasis Rubra Pilaris: A Case Report And Review Of The Literature, Elizabeth A. Warbasse, Taryn Huizenga Md

Medical Student Research Symposium

Pityriasis rubra pilaris (PRP) is an inflammatory papulosquamous disorder of unknown etiology. It is characterized by hyperkeratotic scaling plaques with an orange-red hue, “islands of sparing,” and palmoplantar keratoderma; it may cause erythroderma. There have been no completed controlled clinical trials for the treatment of PRP, and there are no FDA approved treatments at this time; most treatment evidence is derived from case reports. This review of the literature explores the use of various biologics which have been attempted for treatment of widespread or treatment resistant PRP. Some case reports have demonstrated efficacy of anti-IL-17 and anti-IL12/23 agents for PRP …

Probable African Tick Bite Fever In The United States, Kami Lowery, Theodore Rosen

Faculty, Staff and Students Publications

African tick bite fever (ATBF) is a tick-borne rickettsial disease most often observed in North American and European tourists returning home from the southern portion of Africa. Ticks infected with Rickettsia africae transmit this parasitic bacterium to humans, who subsequently develop an influenza-like illness, one or more inoculation eschars, and in some cases, a cutaneous rash. Because ATBF often presents with non-specific symptoms that suggest other infectious diseases, establishing the diagnosis may be difficult. Confirmatory assays, including serology and nucleic acid amplification, may take weeks to return and cannot help with acute treatment decisions. We present a case of a …

Podiatry

Juvenile xanthogranulomas (JXG) are a benign histiocytic cell proliferative disorder in early childhood. They most commonly present within the first two years of life with papular or nodular changes to the skin on the head, neck or upper trunk. Xanthogranulomas are mostly self-limiting, can be singular or multiple, and rarely can infer a systemic disease process1. The purpose of this study was to publish a unique finding of an extra-tendinous solitary mass in an otherwise healthy 17-year old, with surgical and medical treatment after diagnosis.
