Article Abstract
Background: Adverse drug reactions are frequent, with cutaneous manifestations being the most common. In the hospital environment, the incidence of cutaneous drug reactions varies from 2% to 3%.
Objective: To analyze the profile of cutaneous drug reactions, relating clinical forms, suspected medications, histopathological alterations, systemic repercussions, treatment and course.
Methods: Clinical, retrospective and observational study of patients seen by the Dermatology Interconsultation team from January 2013 to December 2016.
Results: The frequency of cutaneous drug reactions among the evaluated patients was 13.6%, with 219 cases diagnosed. In 65.7%, the reaction was considered mild, of which the most common was exanthema, while in 34.2%, the reaction was considered severe, with DRESS being the main form of reaction(18.2%). Antibiotics (36.5%) and anticonvulsants (10%) were the most involved drugs. In addition to drug discontinuation, systemic corticosteroids were prescribed in 47% of cases and intravenous immunoglobulin (IVIg) in 4.5%. Of the mild forms, in 62%, expectant management and/or exclusive use of symptomatic treatment was used.
Study Limitations: Retrospective study, with limitations inherent to this type of investigation; lack of some information in medical records; long evaluation period, with a possible change in external validity.
Conclusion: The most frequently identified clinical form was exanthema, and antibiotics and anticonvulsants were the most frequently involved drug classes. About one-third of the patients had severe cutaneous drug reactions, with DRESS being the main one. Cutaneous drug reactions are frequent in clinical practice, and the dermatologist should be called in as soon as possible to assist in the diagnosis and management of these cases.

High-throughput chemistry (HTC) and direct-to-biology (D2B) platforms allow for plate-based compound synthesis and biological evaluation of crude mixtures in cellular assays. The rise of these workflows has rapidly accelerated drug-discovery programs in the field of targeted protein degradation (TPD) in recent years by removing a key bottleneck of compound purification. However, the number of chemical transformations amenable to this methodology remain minimal, leading to limitations in the exploration of chemical space using existing library-based approaches.

Introduction: Protein acetylation is an extensively investigated post-translational modification (PTM). In addition to lysine acetylation, three new types of lysine acylations characterized by the presence of an acidic carboxylic group have been recently identified and validated. These included lysine malonylation (Kmal), lysine succinylation (Ksucc) and lysine glutarylation (Kglu).

Discontinuation of antiseizure medications (ASMs), primarily prompted by adverse effects, presents a formidable challenge in the management of epilepsy, and impacting up to 25% of patients. This article thoroughly explores the clinical spectrum of cutaneous adverse drug reactions (cADRs) associated with commonly prescribed ASMs. Ranging from mild maculopapular rashes to life-threatening conditions such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), the diverse manifestations are meticulously detailed.

Background And Purpose: Epilepsy increases poor outcomes in patients with post-traumatic brain injury and brain tumor-related epilepsy, for whom early seizure control is essential. Perampanel (PER) was a known third-generation antiepileptic drug for treatment all types of seizures. The objective of the study is to compare clinical outcomes and safety of PER administration as monotherapy.
