MedicalResearch.com Interview with: Niklas Worm Andersson, MD Department of Clinical Pharmacology, Copenhagen University Hospital Bispebjerg and Frederiksberg, Copenhagen NV, Denmark MedicalResearch.com: What is the background for this study? What is Podophyllotoxin used for? Response: Podophyllotoxin is an antimitotic agent primarily used in the local treatment of anogenital warts, which are among the most prevalent sexually transmitted diseases worldwide. Most women affected by anogenital warts are of childbearing age and during pregnancy, they may become symptomatic, enlarge, or multiply. While podophyllotoxin is part of first-line treatment of anogenital warts for the non-pregnant population, it is contraindicated during pregnancy. Fetal safety data are limited and to our knowledge, no previous human data exist to help inform on this issue. (more…)

MedicalResearch.com Interview with: Peter C. Friedman, M.D., Ph.D. Diplomate of the American Academy of Dermatology www.skincenterderm.com MedicalResearch.com: What is the background for this study and case series? Would you describe nonthermal atmospheric pressure plasma? Response: Plasma is essentially ionized gas, the fourth state of matter: molecules or atoms move freely in gas state but in a higher energy state atoms shed electrons and both electrons and ions then move freely and independently. If this material has a temperature close to room temperature, we call it non-thermal atmospheric pressure plasma, or cold plasma. It has been established in countless in vitro and animal experiments that cold plasma has a significant effect on living cells and tissues, for example: selective destruction of cancer cells, helping normal tissue development, inhibiting bacterial, fungal and even viral proliferation. In the handful of clinical trials it could improve wound healing, treat nail fungus. Our group was able to cure precancerous actinic keratosis lesions in a number of patients in a prior study. Based on some of the basic science data regarding the specific molecular and intracellular effects of cold plasma, we theorized that it may be able to cure warts, which are caused by human papilloma virus infection.

MedicalResearch.com Interview with: Richard J. Antaya, MD, FAAD, FAAP Professor, Dermatology and Pediatrics Yale University School of Medicine  MedicalResearch.com: What is the background for this study? Response: Localized hyperthermia has been reported to hasten the resolution of warts and treat both benign and malignant neoplasms. Numerous clinical studies employing various methods to increase the cutaneous surface temperature, including: infrared radiation, radiofrequency, Nd:YAG laser, moxibustion, warm water immersion, ultrasound, and exothermic heat patches, have all yielded positive results. We published a proof-of-concept, open-label trial, representing the largest experience to date employing chemical reaction induced exothermic heat patches for the treatment of warts. Localized hyperthermia from all sources currently has a low level of evidence and strength of recommendation because of the lack of well-designed, sufficiently powered studies.  (more…)

MedicalResearch.com Interview with:

Dr. Christina Lee Chung, MD Associate Professor Department of Dermatology Drexel University

MedicalResearch.com:  What is the background for this study?  What are the main findings?

Response: In early 2016, five years after the inception of our specialty medical-surgical transplant dermatology center, we realized our nonwhite transplant patients were developing skin cancer at higher rates and found interesting trends. These data were published in a previous manuscript. One of the more striking findings was that these patients were developing a high proportion of skin cancer in non-sun-exposed areas such as the genital region. There are no standard guidelines regarding genital skin evaluation and it is unclear how often it is performed in any capacity amongst dermatologists, including practitioners in our center, quite frankly. Our group was concerned that we could be missing skin cancers in this “hidden” area in our high-risk organ transplant population so we launched a quality improvement initiative that incorporated thorough genital skin evaluation as a standard part of post-transplant skin cancer screening.   

Fifteen months after we started this modified screening process, we decided to evaluate the results. To account for any variation in examination, we looked at the findings of a single practitioner. We found that genital lesions are common in the transplant population and include high rates of genital warts and skin cancer. However, patient awareness of the presence of genital lesions was alarmingly low. Nonwhite transplant patients, Black transplant recipients in particular, were disproportionately affected by both genital warts and genital skin cancer in our cohort. Similar to cervical cancer, high-risk HPV types were closely associated with genital squamous cell carcinoma development in our transplant population. (more…)
