Objectives: Red-blue neurofibromas (RBNs), found in up to 29% of adult neurofibromatosis type 1 (NF1) patients, present as red-blue macules measuring 1-2 cm in diameter, primarily on the trunk. Despite their prevalence, RBNs often go unnoticed due to their subtle appearance. Ultrasound characterization serves as a diagnostic clue yet lacks comprehensive studies in both adult and pediatric populations.

The aim was to analyse the consequences of a congested schedule (due to the COVID-19 lockdown) on creatine kinase (CK) in elite football players using GPS tracking technology. A total of 17 elite football players were monitored in training and competition with a global positioning system. Variables including total distance, high-intensity distance, and distance acceleration and deceleration were analysed.

Background: Congenital ichthyoses (CI) comprise a heterogeneous group of genetic diseases requiring lifelong treatment and having a major effect on quality of life. Conventional treatments reduce scaling and skin discomfort; however, they usually have little or no effect on erythema and pruritus. The identification of cytokine alterations in CI raised the possibility of repurposing available biologics.

Article Synopsis
  • A 13-year-old boy was diagnosed with hypohidrotic ectodermal dysplasia (HED) linked to a genetic mutation in the ectodysplasin A (EDA) gene.
  • He presented with small, white papules on his face, particularly around the nose, forehead, and cheeks.
  • Histological analysis showed increased sebaceous lobules in the skin, and there's a suggestion that this might be related to a disruption in the Wnt/β-catenin signaling pathway due to the EDA issue.

The selection of oleaginous bacteria, potentially applicable to biotechnological approaches, is usually carried out by different expensive and time-consuming techniques. In this study, we used Oil Red O (ORO) as an useful dye for staining of neutral lipids (triacylglycerols and wax esters) on thin-layer chromatography plates. ORO could detect minimal quantities of both compounds (detection limit, 0.

Objectives: The aims of this study were to investigate the prevalence of dose reduction in patients with SLE treated with belimumab (BEL) in Spain, analyze treatment modalities, and determine impact on control of disease activity.

Methods: Retrospective longitudinal and multicentre study of SLE patients treated with BEL. Data on disease activity, treatments and outcomes were recorded before and after reduction (6-12 months), and they were compared.

Objectives: To provide an overview on the current use of belimumab (BLM) in SLE patients in clinical practice and to examine its efficacy in terms of standardized outcomes, drug survival, as well as patient and safety profiles.

Methods: A longitudinal retrospective multicentre cohort including SLE patients treated with BLM at 18 Spanish centers. Data was collected upon initiation of BLM, at 6 and 12 months after initiation, and at the last recorded visit.

Microorganism lipid droplet small regulator (MLDSR) is a transcriptional regulator of the major lipid droplet (LD)-associated protein MLDS in Rhodococcus jostii RHA1 and Rhodococcus opacus PD630. In this study, we investigated the role of MLDSR on lipid metabolism and triacylglycerol (TAG) accumulation in R. jostii RHA1 at physiological and molecular levels.

A healthy 2-year-old girl presented with multiple asymptomatic subcutaneous nodules on both legs. Histologically demonstrated calcium deposition within the dermis and subcutaneous tissue consistent with calcinosis cutis. Laboratory abnormalities, underlying genetic conditions, and potential triggering factors were ruled out.

Background: Atopic dermatitis (AD) is the most prevalent inflammatory skin disorder, characterized by impaired epidermal barrier function and an altered immune response, both of which are influenced by vitamin D deficiency. Single-nucleotide polymorphisms (SNPs) in VDR and CYP24A1 have been previously associated with AD.

Objective: We sought to characterize the associations between the VDR and CYP24A1 polymorphisms and the vitamin D and lipid biochemical profile in children diagnosed with AD.

Hereditary palmoplantar keratodermas (PPKs) are a clinically and genetically heterogeneous group of disorders characterized by excessive epidermal thickening of palms and soles. Several genes have been associated with PPK including , a gene encoding a crucial component of desmosomes that has been associated with dominant and recessive keratoderma. We report a patient with recessive erythrokeratoderma (EK) in which whole exome sequencing (WES) prioritized by human phenotype ontology (HPO) terms revealed the presence of the novel variant c.

Article Synopsis
  • R. jostii RHA1 contains a diverse range of acyl-CoA carboxylases, including putative essential and non-essential ACC subunits involved in lipid biosynthesis.
  • Mutant strains lacking specific ACC genes showed that while some enzymes are non-essential for growth, RO04222 plays a significant role in the accumulation of lipids such as triacylglycerol.
  • The findings demonstrate the functional diversity and the varying essentiality of ACCs in actinobacteria, influenced by environmental conditions like nitrogen availability.

Football is a very demanding sport which requires players to exert maximum effort, producing fatigue and eventually injuries. Thermography can be used to detect fatigue and prevent its consequences through thermal asymmetries in the bilateral body areas; however, its adequacy for elite footballers has not been widely studied. Therefore, the objective of the present investigation was to determine the suitability of thermography to detect fatigue in male football players.

The ichthyoses are a large, heterogeneous group of skin cornification disorders. They can be inherited or acquired, and result in defective keratinocyte differentiation and abnormal epidermal barrier formation. The resultant skin barrier dysfunction leads to increased transepidermal water loss and inflammation.

Background And Objectives: The neurofibromatosis 1 (NF1) diagnosis is challenging in young children without a family history of NF1. The aims of this study were to estimate diagnostic delays in children without a family history of NF1 and to examine the effects of using café au lait macules and skin fold freckling as a single diagnostic criterion.

Patients And Methods: Retrospective, descriptive, observational study of all patients diagnosed with NF1 before the age of 18 years who were seen at our hospital.

Article Synopsis
  • The study focuses on the diagnosis of Neurofibromatosis type 1 (NF1) in children, highlighting that it's often delayed without a family history, and aims to compare skin manifestations in NF1 patients to those in the general population.
  • Researchers conducted a case-control study with 108 NF1 patients and 137 healthy controls, finding significantly higher prevalence rates of nevus anemicus (NA) and juvenile xanthogranulomas (JXG) in NF1 patients.
  • The results suggest that NA and JXG should be considered for inclusion in the diagnostic criteria for NF1, especially in young children, due to their strong association with the condition.

Article Synopsis
  • The study investigates the prevalence and characteristics of skin manifestations in children with Neurofibromatosis type 1 (NF1), particularly comparing them to a control group of healthy children.
  • Research included 108 NF1 patients and 137 healthy controls, revealing significantly higher occurrences of nevus anemicus and juvenile xanthogranulomas in NF1 patients.
  • The findings suggest that these skin manifestations are important for diagnosing NF1 in early childhood and may warrant their inclusion in the official diagnostic criteria.

The aims of this study were to analyze the differences of physical demands of non-starter players regarding the playing time during the competition and to evaluate the physical demands of the compensatory training (MD + 1C) for substitute players in elite football. The match statistics and MD + 1C of substitute players from a professional Spanish LaLiga football club were analyzed using a 10-Hz global positioning system (GPS) Apex GPS system device, which has been validated as a reliable and valid method to analyze performance in team sports, during all games of the 2016/2017, 2017/2018 and 2018/2019 seasons. The starting players showed both lower total distances covered and high-intensity actions compared to the substitutes.
