[Lupus Cheilitis: a clinical case report].

Background: Generalized lupus erythematosus (LEG) is an autoimmune disease with cutaneous and mucosal manifestations, with lupus cheilitis (LC) being a rare associated oral presentation. The difficulty in early diagnosis of QL lies in its various clinical forms. Although successful treatments have been described, information on specific management is limited, highlighting the importance of early recognition to improve the prognosis and quality of life of patients.

Granulomatous Panniculitis as an Initial Manifestation of Sjögren Syndrome.

A 65-year-old woman presented with unexplained weight loss, recurrent fever, and a dermatosis with painful nodules on the extremities. Biopsies showed focal lobular panniculitis with neutrophilic microgranulomas. Comprehensive investigations ruled out infection and hematologic and solid organ neoplasms.

[Anti-MDA5 dermatomyositis. Literature review].

Dermatomyositis positive anti-melanoma differentiation-associated gene 5 (anti-MDA5 DM) is a rare disease that represents less than 2%. The prevalence of anti-MDA5 DM ranges from 7 to 60%, with higher prevalence in Asian (11-60%) and women. The clinical picture may be variable and is accompanied by the typical features of dermatomyositis, such as periorbital heliotrope (blue-purple) rash with edema, erythematous rash on the face, or the anterior chest (in a V-sign), and back and shoulders (in a shawl sign), violaceous papules or plaques located on the dorsal part of the metacarpophalangeal or interphalangeal joints, which are pathognomonic by definition; yet, one of the most striking signs is the painful ulceration skin that is found in 82% of cases, which is deep and in punching holes or showing hyperkeratotic crusts.

Predictive factors associated with the persistence of chest pain in post-laparoscopic myotomy and fundoplication in patients with achalasia.

Background: Episodic angina-like retrosternal pain is a prevalent symptom for achalasia patients pre- and post-treatment. The cause of postoperative chest pain remains poorly understood. Moreover, there are no reports on their predictive value for chest pain in the long-term post-treatment.

Nail Changes in People Living with Human Immunodeficiency Virus: Observational and Cross-Sectional Study in a Third-Level Hospital.

Introduction: Nail changes in people living with human immunodeficiency virus (HIV) have been scarcely reported. The aim of this study was to establish the frequency and characteristics of nail alterations observed in adults with HIV infection in a third-level hospital in Mexico.

Method: Observational and cross-sectional study carried out in 205 patients receiving care at the HIV/AIDS Clinic of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (INCMNSZ) in Mexico City.

Pain Management in Patients with Severe Pemphigus Vulgaris.

To describe the pain management and clinical course of patients with severe Pemphigus Vulgaris (PV) admitted to a third-level Intensive Care Unit (ICU). This was a retrospective cohort study conducted in the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán over the period 2013-2020. Study population comprised patients with severe PV admitted to the ICU.

Extracellular Vesicles from Human Plasma Show a Distinctive Proteome and miRNome Profile in Patients with Severe Cutaneous Adverse Reactions.

Cutaneous drug-induced reactions are immune-mediated responses that can lead to life-threatening diseases such as drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome, and toxic epidermal necrolysis, collectively known as severe cutaneous adverse reactions (SCARs). Unfortunately, they cannot be predicted during drug development, and, at present, a prognostic biomarker is not available nor are validated assays for diagnosis. Thus, by using proteomic and microarray miRNA analysis, the cargo of extracellular vesicles obtained from SCARs patients was analyzed and correlated with the severity of the reaction.

Toenail abnormalities in rheumatoid arthritis patients are associated with radiographic damage and impact disability: a cross sectional study nested within a cohort.

Objectives: Cutaneous involvement is an extra-articular manifestation of rheumatoid arthritis (RA). This includes nail abnormalities, which are often overlooked. We described nail findings in RA patients currently attending an early arthritis cohort (n=145), and associated them with disease activity and/or damage, as well as patient-reported outcomes.

MicroRNA Expression in Cutaneous Lupus: A New Window to Understand Its Pathogenesis.

Background: The role of miRNAs in the pathogenesis of cutaneous lupus has not been studied.

Objective: It was to assess the levels of a selected panel of circulating miRNAs that could be involved in the regulation of the immune response, inflammation, and fibrosis in cutaneous lupus.

Methods: It was a cross-sectional study.

[Lamotrigine and its relationship with Stevens-Johnson syndrome and toxic epidermal necrolysis].

Lamotrigine is an antiepileptic drug that has been widely used for epilepsy, as a mood stabilizer (for type 1 bipolar disorder) and in the management of neuropathic pain, it is used both in monotherapy and in complementary therapy. Considered relatively new, approved by the Food and Drug Administration in 1994, its benefits include a greater margin of safety compared to other anticonvulsants. However, although in a lower percentage, it causes severe adverse skin reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis.

Incidence of complications in dermatological surgery of melanoma and non-melanoma skin cancer in patients with multiple comorbidity and/or antiplatelet-anticoagulants. Five year experience in our Hospital.

Introduction: Surgery is performed more frequently now at days, due to the increasing incidence of melanoma and no-melanoma skin cancer. There are different opinions among dermatologic surgeons between to continue or discontinue antithrombotic therapy prior to the procedure, which increases the risk of thromboembolic events. Prophylaxis with oral antibiotics in the postsurgical period is controversial.

Mucocutaneous manifestations in systemic amyloidosis A retrospective analytical study in a tertiary care center.

Background: The mucocutaneous clinical profile of patients with amyloidosis in Latin America has been scarcely reported.

Objective: To describe clinical characteristics of skin and mucosal manifestations in systemic amyloidosis in a tertiary care center in Mexico City.

Methods: A cross sectional, retrospective analytical study was performed in patients with systemic amyloidosis over a 15-year period.

Inflammatory chemokine profiles and their correlations with effector CD4 T cell and regulatory cell subpopulations in cutaneous lupus erythematosus.

We compared the chemokine/receptor expression in skin biopsies of discoid (SLE/DLE) and subacute lupus (SLE/SCLE) and correlated it with tissue and circulating effector CD4 T cells/regulatory cells. Skin biopsies and peripheral blood from 9 active SLE/DLE patients, 9 SLE/SCLE patients, 5 control SLE patients without cutaneous lesions and 10 control healthy donors were included. Clinical skin activity was measured by Cutaneous Lupus Erythematosus Disease Area and Severity Index scoring, and systemic activity was measured by a modified SLEDAI-2K excluding the cutaneous items.
