The use of balneotherapy in dermatology.

Balneotherapy is the treatment of disease by bathing in thermal spring water. This therapy has been used for centuries and remains a popular form of treatment for dermatologic and rheumatologic diseases today. Although the favorable climates of balneotherapy thermal centers have known beneficial effects on psoriasis and atopic dermatitis, the thermal spring waters themselves can also potentially decrease skin inflammation. The addition of phototherapy to balneotherapy, or balneophototherapy, further enhances the anti-inflammatory effects of thermal spring water. We have reviewed the literature on balneotherapy in the treatment of skin diseases, as well as describing their use in three different treatment sites, each with unique climates and chemical properties of the mineral water used in balneotherapy-the Dead Sea in Israel and Jordan, the La Roche-Posay Thermal Center in France, and the Blue Lagoon in Iceland.

Cutaneous Langerhans cell histiocytosis presenting with hypopigmented lesions: Report of two cases and review of literature.

Langerhans cell histiocytosis is a rare group of disorders that results from the abnormal proliferation and accumulation of dendritic-derived cells in various organs of the body, such as the skin and bones. Hypopigmented macules are a rare cutaneous presentation of Langerhans cell histiocytosis that may pose a diagnostic dilemma when no other findings of Langerhans cell histiocytosis are present at the time of examination. We present 2 cases of the hypopigmented variant of Langerhans cell histiocytosis, including a case with histopathologic features of regression, and a review of the literature. These cases highlight the importance of including Langerhans cell histiocytosis in the differential diagnosis of an infant with hypopigmented macules and papules.

Ocular Injury in Cosmetic Laser Treatments of the Face.

BACKGROUND: The eye is a vulnerable and commonly injured organ in cosmetic laser procedures of the face. Treatment of the eyelids and periorbital areas increases this risk, especially when ocular protection devices are not used or are removed during the procedure. A study has shown that injury from laser epilation of the periocular areas is one of the most common causes of litigation in cutaneous laser surgery. OBJECTIVE: The goal of this review is to determine the causes of ocular injury in cosmetic laser procedures and derive lessons on critical safety elements to prevent future injury. METHODS: We conducted a review of the current literature through a PubMed search on case reports of ocular injury in cosmetic laser treatments of the face. Twenty-one cases are examined. RESULTS: In more than 62 percent of cases, ocular protection was not used or protection was used but removed during the procedure to treat areas close to the eye. However, despite the proper use of intraocular corneal shields and wavelength-specific goggles, accidents occurred in 33 percent of cases. CONCLUSION: Ocular protection devices are essential to prevent most cases of laser-induced eye injury. Use of high fluence and long wavelength lasers increases the risk of ocular injury due to deeper penetration of the organ by radiation. Inadequate cooling between pulses also predisposes to injury by cosmetic lasers.

Electronic device generated light increases reactive oxygen species in human fibroblasts.

OBJECTIVES: Our skin is constantly exposed to light from solar radiation and electronic devices, which impact skin physiology and aging. The biological altering properties of ultraviolet (UV) solar radiation on skin have been well established. There is significant scientific and public interest on the effects of electronic device generated light (EDGL) on skin. Currently, the effects of EDGL on skin are largely unknown. EDGL includes UV, visible, and infrared light from consumer electronics such as smartphones, computers, and televisions. In this study, we measured the wavelength specific irradiance from electronic devices, and irradiated fibroblasts with white EDGL to determine changes in reactive oxygen species generation, apoptosis, and necrosis. METHODS: To determine the EDGL output of commonly used consumer electronic devices, we measured the irradiance from electronic devices at the manufacturers' recommended reading distances and at 1 cm. To determine the effect of EDGL on human skin cells, we irradiated AG13145 fibroblasts with EDGL for 1 hour at a distance of 1 cm and measured changes in reactive oxygen species generation, apoptosis, and necrosis. RESULTS: ROS increased significantly by 81.71%, 85.79%, and 92.98% relative to control following 1 hour of white EDGL from iPhone 8+, iPhone 6, and iPad (first generation), respectively. There was a non-significant change in apoptosis following irradiation with an iPhone 8+, iPhone 6, and iPad. Total necrosis was less than 2% for all treatment and control groups. CONCLUSIONS: Our results suggest that short exposures of EDGL increase ROS generation, but the long-term effects associated with repeated exposures of EDGL are unknown. As electronic devices become more widely used and integrated into society globally, we anticipate greater scientific research and general public interest on the effects of visible EDGL on skin.

Review: the reemergence of brachytherapy as treatment for non-melanoma skin cancer.

Electronic brachytherapy (EBT) has seen a significant rise in use over the past few years in treating non-melanoma skin cancer (NMSC). However, the current literature in EBT remains scarce. Existing data on high-dose rate brachytherapy (HDR-BT) with surface applicators is often used to justify its efficacy and safety. In this review we study the two treatment modalities on their efficacy in treating NMSC and we explore the reasons behind the recent uprise in EBT. A literature review using PubMed was performed for articles published until January 2017 studying efficacy of HDR-BT and EBT for treating NMSC. HDR-BT demonstrated effective local control ranging from 96.2% to 100% up to 66 months of follow-up with acceptable cosmesis. For EBT, local control rates ranged from 90% to 100% with generally favorable tolerance and cosmesis outcome after roughly one year. While longer term data on EBT is needed, its short term efficacy shows promise as a possible alternative to surgery or other radiation therapy in a select group of patients.
