Yeast-based screening of cancer mutations in the DNA damage response protein Mre11 demonstrates importance of conserved capping domain residues.

DNA damage response (DDR) pathways are initiated to prevent mutations from being passed on in the event of DNA damage. Mutations in DDR proteins can contribute to the development and maintenance of cancer cells, but many mutations observed in human tumors have not been functionally characterized. Because a proper response to DNA damage is fundamental to living organisms, DDR proteins and processes are often highly conserved.

Nonsurgical Treatments for Nonmelanoma Skin Cancer.

Although surgical intervention remains the standard of care for nonmelanoma skin cancer, other treatment modalities have been studied and used. Nonsurgical treatment methods include cryotherapy, topical medications, photodynamic therapy, radiation therapy, Hedgehog pathway inhibitors, programmed cell death protein 1 inhibitors, and active nonintervention. Despite the favorable efficacy of surgical treatment methods, many factors, including but not limited to patient age, preference, and severity of disease, must be taken into consideration when choosing the most appropriate, patient-centered treatment approach.

Female Genital Itch.

Vulvar pruritus is a common complaint among young girls and women presenting to primary care physicians, gynecologists, and dermatologists. Female genital itch is especially disruptive because of its interference with sexual function and intimacy. Causes of vulvar itch are vast and may be inflammatory, environmental, neoplastic, or infectious, often with several causes coexisting simultaneously.

Understanding the influence of social media in medicine: lesson learned from Facebook.

Atopic dermatitis is a very common chronic skin disease. With increasing number of patients searching social media outlets such as Facebook for medical information, social media can be used by physicians as a powerful educational tool. We analyzed the unmoderated Q&A series on Facebook begun by members of National Eczema Association Scientific Advisory Committee.

Women in medicine and dermatology: history and advances.

The history of women in medicine has been marked by many challenges and achievements. Although the role of women in the "art of healing" can be traced back many centuries, only males are traditionally highlighted in history. Across antiquity, access to medical education was denied to females.

Intralesional treatment for keloids and hypertrophic scars: a review.

Background: Although differing in clinical presentation and prognosis, keloids and hypertrophic scars are generally characterized by abnormally proliferative scar tissue and are extremely debilitating. Several intralesional therapies have been studied in attempts to find a universally safe and effective modality, of which there are currently none.

Objective: To provide a comprehensive review of current intralesional treatment modalities for keloids and hypertrophic scars.

Pyschodermatology: a trip through history.

The interaction between the mind and diseases of the skin has been the study focus for many researchers worldwide. The field of Psychodermatology, or Psychocutaneous Medicine, is the result of the merging of two major medical specialties, psychiatry and dermatology. Although the history of Psychodermatology is rather old and interesting, the field has only recently gained popularity.

Inflammatory nodules following soft tissue filler use: a review of causative agents, pathology and treatment options.

Nodule development is a common complication following the use of fillers for soft tissue augmentation and is commonly categorized as inflammatory or non-inflammatory in nature. Inflammatory nodules may appear anywhere from days to years after treatment, whereas non-inflammatory nodules are typically seen immediately following implantation and are usually secondary to improper placement of the filler. Although inflammatory nodules are more common with permanent fillers such as silicone, inflammatory nodule development following administration of temporary fillers such as hyaluronic acid and collagen has also been reported.

Carbon dioxide laser for the treatment of microcystic lymphatic malformations (lymphangioma circumscriptum): a systematic review.

Background: Lymphangioma circumscriptum (LC) is a rare, superficial, cutaneous lymphatic malformation. Management is difficult because of high recurrence rates, regardless of the treatment modality chosen. The carbon dioxide (CO2 ) laser may offer a less-invasive option than surgery that provides satisfactory functional and cosmetic results.

Laser and light therapy for onychomycosis: a systematic review.

More than just a cosmetic concern, onychomycosis is a prevalent and extremely difficult condition to treat. In older and diabetic populations, severe onychomycosis may possibly serve as a nidus for infection, and other more serious complications may ensue. Many treatment modalities for the treatment of onychomycosis have been studied, including topical lacquers and ointments, oral antifungals, surgical and chemical nail avulsion, and lasers.

Lasers for cutaneous congenital vascular lesions: a comprehensive overview and update.

The use of laser to treat cutaneous lesions began with Dr. Leon Goldman and his coworkers in 1963. Ten years later, these authors described promising effects on angiomas using the continuous-wave neodymium:yttrium-aluminum-garnet laser.
