Vascular uses of LP1064 applicator on the harmony XL pro device.

INTRODUCTION: Vascular lesions of the lower extremities and face, such as varicose veins and telangiectasias, are a common dilemma for the dermatologist. In recent years, laser therapy has emerged as a viable treatment option for these vascular anomalies. MATERIALS AND METHODS: Although there are several types of lasers, the 1064-nm Nd:YAG in particular is popularly selected for its safety profile and versatility. The longer 1064 nm wavelength penetrates deeper into the skin while also being less absorbed by hemoglobin and melanin, thus resulting in minimized damage to surrounding structures and less pigmentation changes. The new LP1064 applicator on the Harmony XL Pro Device is one such laser. RESULTS: Numerous publications have corroborated the efficacy of 1064 nm Nd:YAG lasers. These studies cite at least over 75% of patients experiencing significant improvement in common vascular lesions. Efficacy of this laser is also seen for other vascular lesions such as port wine stains, hemangiomas, venous lakes, poikiloderma of Civatte, and angiokeratomas. Overall, the reported studies also show a low incidence of adverse events. CONCLUSION: The 1064 nm Nd:YAG laser, such as the Harmony LP1064 applicator, is a safe and effective tool to treat vein anomalies of the face and leg. Although commonly used for vein ablation, it has demonstrated a robust response in other indications as well.

Complete Response to tenalisib and romidepsin with long-term maintenance using tenalisib monotherapy in a patient with relapsed and refractory sézary syndrome.

Mycosis fungoides (MF) and Sézary Syndrome (SS) are the most common subtypes of cutaneous T cell lymphomas (CTCL). Advanced-stage MF/SS have poor prognoses and may be refractory to multiple systemic treatments. These cases can be difficult to achieve and maintain complete response and there is a need for novel therapeutics. Inhibition of the phosphatidylinositol 3-kinase (PI3K) pathway by Tenalisib presents one such emerging drug. We report a relapsed/refractory SS patient achieving complete remission using the combination of Tenalisib and Romidepsin and subsequently maintaining long-duration CR with Tenalisib monotherapy.

Contemporary review of dermatologic conditions in space flight and future implications for long-duration exploration missions.

BACKGROUND: Future planned exploration missions to outer space will almost surely require the longest periods of continuous space exposure by the human body yet. As the most external organ, the skin seems the most vulnerable to injury. Therefore, discussion of the dermatological implications of such extended-duration missions is critical. OBJECTIVES: In order to help future missions understand the risks of spaceflight on the human skin, this review aims to consolidate data from the current literature pertaining to the space environment and its physiologic effects on skin, describe all reported dermatologic manifestations in spaceflight, and extrapolate this information to longer-duration mission. METHODS AND MATERIALS: The authors searched PubMed and Google Scholar using keywords and Mesh terms. The publications that were found to be relevant to the objectives were included and described. RESULTS: The space environment causes changes in the skin at the cellular level by thinning the epidermis, altering wound healing, and dysregulating the immune system. Clinically, dermatological conditions represented the most common medical issues occurring in spaceflight. We predict that as exploration missions increase in duration, astronauts will experience further physiological changes and an increased rate and severity of adverse events. CONCLUSION: Maximizing astronaut safety requires a continued knowledge of the human body's response to space, as well as consideration and prediction of future events. Dermatologic effects of space missions comprise the majority of health-related issues arising on missions to outer space, and these issues are likely to become more prominent with increasing time spent in space. Improvements in hygiene may mitigate some of these conditions.

How to Address Scar Pincushioning and Webbing of the Nasal Dorsum Using Surgical Defatting and Z-plasty.

Nonmelanoma skin cancer is the most common cancer, typically growing in sun-exposed areas, such as the nose. After complete excision of the tumor, the subsequent scar may exhibit multiple complications that are easily noticeable and cosmetically unsatisfactory. When performing a revision of such a scar, using a single surgical technique may be insufficient; rather, the surgeon may need to carefully plan and utilize several techniques to achieve the best cosmetic outcome. Here, we report a case that demonstrates successful use of surgical defatting and Z-plasty techniques to revise a scar of the nasal dorsum that exhibited pincushioning and webbing.

Takotsubo syndrome: A current review of presentation, diagnosis, and management.

Takotsubo syndrome is a syndrome of acute heart failure due to left ventricular systolic dysfunction that is associated with increased cardiovascular morbidity and mortality. It occurs in both sexes and at all ages, but predominates in post-menopausal women for reasons that are unclear. In a patient who presents with cardiac symptoms, electrocardiographic changes, and/or biomarker elevation indicating myocardial stress (i.e. troponin elevation), this condition should be considered in the differential diagnosis. Cardiac imaging is critical for a timely diagnosis of this condition and has management implications. This syndrome can occur with or without underlying coronary artery disease, and while there are various characteristic myocardial patterns described on imaging, the most common one is left ventricular dysfunction due to apical stunning with basal hyperkinesis. In the acute phase, Takotsubo syndrome can lead to life-threatening sequelae, including cardiogenic shock, pulmonary edema, thromboembolism, and arrhythmias. Multiple pathophysiologic mechanisms are implicated, including an acute increase in left ventricular afterload in the setting of sympathetic activation with a catecholamine storm, multi-vessel coronary vasospasm, coronary endothelial microvascular dysfunction, and inflammation. In this review, we discuss the current knowledge surrounding presentation, diagnosis, and treatment of this under-diagnosed condition.

Adverse Events of Non-Invasive Body Contouring: Analysis of the Food and Drug Administration Manufacturer and User Facility Device Experience Database.

BACKGROUND: Multiple non-invasive modalities have become popular alternatives to surgical procedures for body contouring. OBJECTIVE: To analyze adverse events (AEs) associated with non-invasive body contouring devices reported through the Manufacturer and User Facility Device Experience (MAUDE) database. METHODS AND MATERIALS: The MAUDE database were queried for AEs associated with non-invasive body contouring devices between January 2011 and June 2021. An extensive list of keywords and brand and manufacturer names was used. RESULTS: A total of 1,325 reports with 1,590 AEs were identified among 6 modalities. More than 70% were reported in the past 5 years. Cryolipolysis made up 38.3% reports, which mostly pertained to paradoxical hyperplasia and hernias. Radiofrequency had the most reports (41.9%). Like laser devices, most of their reports described burns. Focused ultrasound was commonly associated with unintentional fat loss and surface irregularities. Focused electromagnetic field resulted in only 7 reports. CONCLUSION: The analysis of present study supports previous studies concerning common local symptoms caused by these devices, but it also reveals complications not reported in previous device studies. This study highlights the importance of proper technique and adherence to device guidelines. Practitioners should be knowledgeable of potential complications from each device to both prevent and manage them accordingly.

Squamous cell carcinoma arising in an epidermal inclusion cyst.

Squamous cell carcinoma (SCC) arising from an epidermal inclusion cyst (EIC) is uncommon. We present a case of a 70-year-old man with a scalp nodule with persistent discharge that was resected based on the clinical impression of an EIC. Histopathologic exam showed an infundibular EIC with an epidermal type of squamous epithelium; however, some of the cyst lining and lumen was replaced by squamous proliferation with malignant features. There are 56 cases of SCC arising in EICs reported in the English literature. Though suspected EICs are commonly benign, a thorough pathologic evaluation is required to rule out malignancy.

Analysis of adverse events with sclerosants reported to the United States Food and Drug Administration.

OBJECTIVES: To analyze adverse events (AEs) related to sclerosants reported through the Federal Adverse Event Reporting System (FAERS). METHODS: We queried the FAERS database for all cases associated with sclerosants. Reports were analyzed and stratified based on severity of cases and patient death. RESULTS: A total of 1215 cases with 3124 reactions were identified among 4 sclerosants. "General disorder and administration site conditions" reaction group was prevalent in all sclerosants. For polidocanol, deep vein thrombosis and pulmonary embolism were the most common severe reactions while cardiac arrest was frequent in death cases. Anaphylaxis was common in fatalities of sodium tetradecyl sulfate. Ethanolamine oleate was associated with procedural errors, while morrhuate sodium resulted in few cases. CONCLUSION: Our analysis supports previous studies concerning common local symptoms, but also reveals serious and death associated reaction profiles specific to individual sclerosants. Practitioners should be knowledgeable on both non-lethal and fatal AEs for each sclerosant. The multitude of reports concerning serious reactions and deaths we report herein provide a cautionary reminder to venous practitioners and patients that sclerotherapy is not a trivial procedure.

A rare case of lues maligna in an HIV-negative woman.

We describe an HIV-negative 43-year-old woman presenting with a diffuse ulceronodular eruption and positive serological tests for syphilis consistent with lues maligna. Lues maligna is a severe and rare variant of secondary syphilis characterized by prodromal constitutional symptoms followed by the formation of multiple well-circumscribed nodules with ulceration and crust. This case depicts a particularly rare presentation as lues maligna usually involves HIV-positive men. The clinical presentation of lues maligna can pose a diagnostic challenge, with infections, sarcoidosis, and cutaneous lymphoma as just a few entities in its broad differential diagnosis. However, with a high index of suspicion, clinicians can diagnose and treat this entity earlier and reduce morbidity.

Incidence of Difficult Laryngoscopy in Adult Congenital Heart Disease Patients: A Retrospective Cohort Study.

OBJECTIVE: To identify the incidence of difficult intubation in patients with adult congenital heart disease (ACHD) undergoing cardiac surgery or catheterization. DESIGN: A retrospective cohort study. SETTING: A single-center academic quaternary pediatric hospital. PARTICIPANTS: All patients were >18 years of age with ACHD undergoing endotracheal intubation within the Heart Center at Texas Children's Hospital between January 2012 and December 2019. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: A retrospective chart review was performed, including patient demographics, preoperative airway assessment and intraoperative airway management characteristics. Airways were categorized as difficult using the Pediatric Difficult Intubation registry operational definitions. For patients classified as having a difficult airway, the preoperative airway examination findings were recorded in addition to factors associated with difficult airway in the adult. The study authors identified 1,029 patients with ACHD who underwent procedures with anesthesia at their institution and were analyzed for the presence of difficult airway. In total, 878 patients were intubated, with 4.3% (n = 38) identified to have difficult airway. The presence of concomitant syndromes was greater in patients with difficult intubations and those who were not intubated compared with those who were not difficult intubations (23.7% and 17.2 v 7.5; p < 0.001), respectively. Most patients did not have typical signs associated with difficult intubation. CONCLUSIONS: The study authors identified an incidence of difficult laryngoscopy in their cohort of ACHD patients to be 4.3%. Their incidences of difficult laryngoscopy were fewer than that reported in adult patients with noncongenital heart disease. Most importantly, the risk factors associated with difficult laryngoscopy in the normal adult may be different from those presenting with ACHD, necessitating further investigation.

Dermatitis Herpetiformis: An Update on Diagnosis, Disease Monitoring, and Management.

Dermatitis herpetiformis (DH), Duhring disease, is caused by gluten sensitivity and affects 11.2 to 75.3 per 100,000 people in the United States and Europe with an incidence of 0.4 to 3.5 per 100,000 people per year. DH is characterized by a symmetrical blistering rash on the extensor surfaces with severe pruritus. The diagnosis continues to be made primarily by pathognomonic findings on histopathology, especially direct immunofluorescence (DIF). Recently, anti-epidermal transglutaminase (TG3) antibodies have shown to be a primary diagnostic serology, while anti-tissue transglutaminase (TG2) and other autoantibodies may be used to support the diagnosis and for disease monitoring. Newly diagnosed patients with DH should be screened and assessed for associated diseases and complications. A gluten-free diet (GFD) and dapsone are still mainstays of treatment, but other medications may be necessary for recalcitrant cases. Well-controlled DH patients, managed by a dermatologist, a gastroenterologist, and a dietician, have an excellent prognosis. Our review comprehensively details the current diagnostic methods, as well as methods used to monitor its disease course. We also describe both the traditional and novel management options reported in the literature.
