This study investigates serum cell-free DNA fluctuations in patients with herpes zoster or post-herpetic neuralgia, offering insight into the tissue damage and inflammatory dynamics associated with these conditions. A single-centre combined cross-sectional and longitudinal study was conducted with 59 patients to assess cell-free DNA levels in herpes zoster and post-herpetic neuralgia. Cell-free DNA was extracted from blood samples of patients with herpes zoster or post-herpetic neuralgia and compared with healthy controls.

Mastocytosis is characterized by abnormal clonal mast cell proliferation. Given the paucity of data in patients with mastocytosis, it is crucial to assess the safety of COVID-19 vaccines in this population. We aimed to assess the risk of allergic reactions and the effect of COVID-19 infection among patients with mastocytosis.

Background: Mycosis fungoides (MF) in solid-organ transplant recipients (SOTRs) is rare, with limited data on disease characteristics.

Objective: The aim was to study the characteristics of MF in SOTRs with an emphasis on the immunosuppressive therapy.

Methods: A retrospective cohort of patients diagnosed with MF, who were also SOTRs, were followed at 3 cutaneous lymphoma outpatient clinics, between January 2010 and February 2022.

Atopic dermatitis (AD) is a chronic inflammatory skin disease affecting up to 20% of children. Methotrexate (MTX) is used off-label as a systemic treatment for AD patients unresponsive to topical therapies, but limited data exist regarding its safety and efficacy in children, especially in those < 4 years old. To further investigate MTX in younger patients, we screened the medical records of three referral centers between 2016 and 2022 and identified 28 infants and toddlers < 4 years old with AD treated with MTX.

Tuberous sclerosis complex (TSC) is a rare genetic disease with neurocutaneous manifestations, often presenting initially to the dermatology clinic. We report a cohort of neonates who presented with a novel finding of white epidermal nevus and were eventually diagnosed with TSC. White epidermal nevus may be yet another dermatological finding that may aid in the early diagnosis of TSC.

Article Synopsis
  • - Patients with primary immunodeficiency disorders (PIDs) often experience unique and severe skin infections due to their compromised immune systems, highlighting the challenges in diagnosis and treatment
  • - A study reviewed cases of eight children with PIDs who presented with atypical skin infections, noting their average diagnosis age and types of infections, which included serious cases like ulcerative-hemorrhagic varicella-zoster virus and resistant scabies
  • - The findings emphasize the importance of recognizing unusual infectious skin manifestations in PID patients, which can lead to critical treatment interventions and improved outcomes

Background And Aims: Skin eruptions are prevalent among patients with inflammatory bowel diseases (IBD), often associated with therapies and frequently leading to dermatological consults and treatment interruptions. We aimed to assess the impact of joint shared decision-making in a multidisciplinary (MDT) IBD-DERMA clinic.

Methods: This retrospective cohort study assessed a consecutive group of patients with IBD who were referred for consultation in an MDT clinic at a tertiary referral center in Israel.

Targeted medications and immunotherapies are being developed to specifically target the pathways involved in tumours. There is limited experience with these new medications and their cutaneous side-effects in the paediatric population. A retrospective study of all paediatric oncological patients treated with targeted therapies and immunotherapies between 1 January 2013 and 1 August 2020 was carried out in 2 haemato-oncological referral centres.

Background: Cutaneous manifestations of dedicator of cytokinesis 8 gene (DOCK8) deficiency, a combined type of T and B cell immunodeficiency, previously designated as autosomal recessive hyper IgE syndrome, includes dermatitis and skin infections. There are limited treatment options for dermatitis related to the syndrome.

Objective: To describe a cohort of patients with DOCK8 deficiency with a focus on the treatment of their cutaneous manifestations.

Article Synopsis
  • The study examined the effectiveness of topical treatments for managing the rash caused by epidermal growth factor receptor inhibitors (EGFRIs) in cancer patients, which occurs in 60-85% of cases.
  • In a randomized trial, patients received either a combination ointment (chloramphenicol and prednisolone), chloramphenicol alone, or aqua cream to see how they influenced rash severity.
  • Results showed that the combination ointment significantly reduced the incidence of a specific type of significant rash compared to the aqua cream, suggesting it is a better prophylactic treatment.

Background/objectives: Joint manifestations are a feature of many pediatric skin disorders, among them psoriasis, autoimmune and autoinflammatory diseases, hypermobility disorders, and as an adverse effect of certain medications. Identifying joint disease early is important for intervention and prevention of chronic damage. However, pediatric musculoskeletal complaints are common and determining whether symptoms warrant a rheumatology referral for arthritis can be challenging.

Cutaneous leishmaniasis poses a therapeutic challenge in the paediatric population. The aim of this study was to assess the efficacy and safety of miltefosine treatment for Old World cutaneous leishmaniasis in paediatric patients. A multicentre retrospective review of 10 children (≤ 18 years of age) with cutaneous leishmaniasis treated with miltefosine in Israel was performed.

Standard clinical care in neonatal and pediatric intensive-care units (NICUs and PICUs, respectively) involves continuous monitoring of vital signs with hard-wired devices that adhere to the skin and, in certain instances, can involve catheter-based pressure sensors inserted into the arteries. These systems entail risks of causing iatrogenic skin injuries, complicating clinical care and impeding skin-to-skin contact between parent and child. Here we present a wireless, non-invasive technology that not only offers measurement equivalency to existing clinical standards for heart rate, respiration rate, temperature and blood oxygenation, but also provides a range of important additional features, as supported by data from pilot clinical studies in both the NICU and PICU.

Background: In the literature, there are minimal data for the treatment of grade 2 or 3 morbilliform/atypical target lesion rashes secondary to sorafenib or vemurafenib given for patients with advanced stage cancer. This poses a dilemma for clinicians, particularly in patients with advanced neoplastic disease for whom other optional treatments are limited.

Methods: The cohort included data on all patients attending the dermato-oncological clinic at a tertiary medical center that presented in 2011-2014 with a widespread rash following treatment with sorafenib or vemurafenib.
