BRAF Inhibitor-Associated Granulomatous Dermatitis: A Report of 3 Cases.

Cutaneous toxicities associated with BRAF inhibitor treatment in patients with metastatic melanoma have been well described. We present a rare association of granulomatous dermatitis in association with the BRAF inhibitor vemurafenib. Three patients with metastatic melanoma all presented with asymptomatic papular eruptions 8-21 months into vemurafenib therapy. Skin biopsies confirmed the diagnosis of granulomatous dermatitis. Other causes of granulomatous dermatitis including infectious agents and sarcoid were excluded. Treatment with potent topical and oral steroids improved the eruptions, but only after the cessation of vemurafenib did all 3 cases of granulomatous dermatitis completely resolve within 2 weeks. It is important to recognize that this association, unlike most other BRAF inhibitor-related skin toxicities, can occur many months after commencement of therapy and that vemurafenib treatment can be continued without clinically significant adverse effects.

A Comprehensive Review on the Significance of Cysteine in Various Metabolic Disorders; Particularly CVD, Diabetes, Renal Dysfunction, and Ischemic Stroke.

Metabolic disorders have long been a challenge for medical professionals and are a leading cause of mortality in adults. Diabetes, cardiovascular disorders (CVD), renal dysfunction, and ischemic stroke are the most prevalent ailments contributing to a high mortality rate worldwide. Reactive oxygen species are one of the leading factors that act as a fundamental root cause of metabolic syndrome. All of these disorders have their respective treatments, which, to some degree, sabotage the pathological worsening of the disease and an inevitable death. However, they pose a perilous health hazard to humankind. Cysteine, a functional amino acid shows promise for the prevention and treatment of metabolic disorders, such as CVD, Diabetes mellitus, renal dysfunction, and ischemic stroke. In this review, we explored whether cysteine can eradicate reactive oxygen species and subsequently prevent and treat these diseases.

Biomarkers and Novel Therapies of Diabetic Neuropathy: An Updated Review.

Diabetic neuropathy is a persistent consequence of the biochemical condition known as diabetes mellitus. As of now, the identification and management of diabetic neuropathy continue to be problematic due to problems related to the safety and efficacy of existing therapies. This study examines biomarkers, molecular and cellular events associated with the advancement of diabetic neuropathy, as well as the existing pharmacological and non-pharmacological treatments employed. Furthermore, a holistic and mechanism-centric drug repurposing approach, antioxidant therapy, Gene and Cell therapies, Capsaicin and other spinal cord stimulators and lifestyle interventions are pursued for the identification, treatment and management of diabetic neuropathy. An extensive literature survey was done on databases like PubMed, Elsevier, Science Direct and Springer using the keywords "Diabetic Neuropathy", "Biomarkers", "Cellular and Molecular Mechanisms", and "Novel Therapeutic Targets".Thus, we may conclude that non-pharmacological therapies along with palliative treatment, may prove to be crucial in halting the onset of neuropathic symptoms and in lessening those symptoms once they have occurred.
