Objectives: Dysbiosis of the skin microbiota has been identified as a key factor in the development of acne. This study was aimed to evaluate the effect of a facial cream gel containing a biotechnological phytocomplex, niacinamide and succinic acid on the bacterial diversity of subjects with mild-moderate acne and its clinical benefits due to microbiota changes.

Methods: Open-label, clinical study in 44 subjects with mild-moderate acne treated with a facial cream gel for 8 weeks.

Patients with recessive dystrophic epidermolysis bullosa (RDEB) experience numerous complications, which are exacerbated by inflammatory dysregulation and infection. Understanding the immunological mechanisms is crucial for selecting medications that balance inflammation control and immunocompetence. In this cross-sectional study, aiming to identify potential immunotherapeutic targets and inflammatory biomarkers, we delved into the interrelationship between clinical severity and systemic inflammatory parameters in a representative RDEB cohort.

Background: The disruption of the microbial community or dysbiosis alters the functional composition, metabolic activity, and local distribution of the microbiota leading the development of acne. The aim of this study is to evaluate the effect of a lotion containing a biotechnological phytocomplex, niacinamide, and succinic acid in the bacterial diversity of subjects with truncal mild-moderate acne and its clinical benefits due to microbiota changes.

Materials And Methods: Open, clinical study in 43 subjects with truncal mild-moderate acne treated with a lotion for 8 weeks.

Cystic echinococcosis (CE) causes significant losses in Andean livestock production and affects Andean food security. However, more studies are needed to understand the epidemiology of the disease. In addition, the potential contribution of Andean cattle to the transmission of Echinococcus granulosus sensu lato needs to be known.

This study aimed to estimate the prevalence and distribution patterns of Sarcocystis spp. in cattle tissues in Chachapoyas province in the Peruvian tropical Andes. Additionally, the risk factors associated with the prevalence and the correlation of two diagnostic techniques (direct microscopy of squashed fresh muscle tissues and histopathology) were explored.

Background: Approved systemic treatment options are limited for pediatric patients with moderate to severe plaque psoriasis.

Objective: To assess the efficacy and safety of apremilast over 16 weeks in pediatric patients with plaque psoriasis.

Methods: SPROUT (NCT03701763) was a phase 3, multicenter, randomized, double-blind, placebo-controlled study of apremilast in patients aged 6-17 years with moderate-to-severe psoriasis (Psoriasis Area and Severity Index [PASI] ≥12, body surface area ≥10%, static Physician Global Assessment [sPGA] ≥3) inadequately controlled by/inappropriate for topical therapy.

Article Synopsis
  • * A case study of fetal junctional epidermolysis bullosa in a consanguineous couple highlights antenatal ultrasound signs like polyhydramnios and skin desquamation, suggesting the condition's presence.
  • * The study introduces a new ultrasound sign - marked perioral hipoecogenicity - which may aid in diagnosing the disease, while also emphasizing the challenges of prenatal ultrasound diagnosis.

Background: Epidermolysis bullosa (EB) is frequently complicated by skin infection, which can lead to bacteremia. However, bloodstream infections (BSI) in patients with EB have not been well described.

Methods: Retrospective study of BSI in children 0-18 years with EB from a national reference unit in Spain, in 2015-2020.

Peru is currently one of the world’s leading culinary destinations, whose world-renowned cuisine uses vegetables, mainly lettuce, as frequent ingredients. Vegetable consumption is promoted worldwide as a part of a healthy diet. However, vegetables, more frequently lettuce, have been implicated as a vehicle of infection for several foodborne parasites.

Background: Atopic dermatitis (AD) is associated with different comorbidities.

Objective: To develop evidence-based and practical recommendations for comorbidity detection in patients with AD in daily practice.

Methods: We employed a modified RAND/UCLA methodology, including a systematic literature review (SLR).

Importance: Epidermolysis bullosa simplex with muscular dystrophy (EBS-MD) is an autosomal recessive disorder caused by pathogenic variants in PLEC1, which encodes plectin. It is characterized by mild mucocutaneous fragility and blistering and muscle weakness. Translational readthrough-inducing drugs, such as repurposed aminoglycoside antibiotics, may represent a valuable therapeutic alternative for untreatable rare diseases caused by nonsense variants.

Article Synopsis
  • The study highlights the complexity of diagnosing and managing atopic dermatitis (AD) due to diverse patient presentations and treatment options.
  • A Delphi method was used to gauge the opinions of dermatologists on AD management, resulting in a questionnaire with 58 items, where consensus was achieved on only 22 items (37.9%).
  • The findings indicate a significant lack of agreement among dermatologists in the management of AD, suggesting a need for better guideline implementation and further research in real-world contexts.

Recessive dystrophic epidermolysis bullosa (RDEB) is an incurable inherited mucocutaneous fragility disorder characterized by recurrent blisters, erosions, and wounds. Continuous blistering triggers overlapping cycles of never-ending healing and scarring commonly evolving to chronic systemic inflammation and fibrosis. The systemic treatment with allogeneic mesenchymal cells (MSC) from bone marrow has previously shown benefits in RDEB.

  • Barraquer-Simons syndrome (BSS) is a rare condition where there is a selective loss of fat from the upper body while retaining fat in the lower body, but its cause remains unclear.
  • A study monitored an 11-year-old girl with BSS over 5 years, examining her clinical condition and various immunological factors, while noting a progression of her fat loss and detecting no significant abnormalities besides this.
  • Findings revealed that there was hyperactivation of the complement system in her adipose tissue, indicated by specific immune markers, suggesting that this may contribute to the fat loss observed in BSS.

Mosaicism denotes an individual who has at least two populations of cells with distinct genotypes that are derived from a single fertilized egg. Genetic variation among the cell lines can involve whole chromosomes, structural or copy-number variants, small or single-nucleotide variants, or epigenetic variants. The mutational events that underlie mosaic variants occur during mitotic cell divisions after fertilization and zygote formation.

Nilotinib is a new multitargeted tyrosine kinase inhibitor, which is used to treat chronic myelogenous leukemia when intolerance or recurrence to imatinib occurs. We report the case of a 14-year-old patient being treated with nilotinib who developed a keratosis pilaris-like eruption. This cutaneous adverse effect is a rare but increasingly reported side effect of this therapy.

Fasciolosis is a zoonotic food- and waterborne infection related to great economic losses on ruminant production. In order to determine the prevalence of bovine liver condemnations due to fasciolosis in an abattoir at the Central Andes of Peru, we evaluated the records of an authorized slaughterhouse in Huancayo, at 3300 m above sea level, over 16 months. Subsequently, the average weights of condemned viscera and carcasses were also estimated to determine the direct and indirect economic losses.

Atopic dermatitis (AD) is a chronic cutaneous inflammatory disorder, characterized by skin barrier disruption. Dermacare is a new cosmetic formulation, which enhances moisturization, reinforces and repairs the skin barrier, and prevents cutaneous microbiota imbalance. To demonstrate its safety and efficacy, a prospective, open-label, and multicenter study was carried out on patients diagnosed with mild to moderate AD.

Investigation of genetic determinants of Mendelian skin disorders has substantially advanced understanding of epidermal biology. Here we show that mutations in PERP, encoding a crucial component of desmosomes, cause both dominant and recessive human keratoderma. Heterozygosity for a C-terminal truncation, which produces a protein that appears to be unstably incorporated into desmosomes, causes Olmsted syndrome with severe periorificial and palmoplantar keratoderma in multiple unrelated kindreds.
