    Abstract Purpose: PUVA phototherapy is indicated for various dermatological conditions. Adverse events due to PUVA phototherapy are seen in a sizable number of patients and can result in therapy cessation. This review will focus on PUVA pricks, an adverse event first reported by Tegner in 1979.
    Methods: Articles were retrieved from PubMed starting from January 1979 until February 2021 yielding 1228 unique articles. Articles were included when they described individual patient characteristics, and patients were treated with PUVA therapy.
    Results: After screening, 33 patients were extracted from 9 articles, published between 1979 and 2005.
    Conclusion: PUVA pricks are paroxysmal episodes of burning or prickling pain, akin to peripheral neuropathy of the unmyelinated C-fibers. Increased excitability of TRPV1 and TRPA1 channels while under PUVA therapy might be a contributing factor. Effective topical treatment options for PUVA pricks are capsaicin 8% cream, urea 4%, or petrolatum emollients. Antiepileptics such as phenytoin, clonazepam, and gabapentin are acceptable oral treatment options. A possible role of N-acetylcysteine in the prevention of PUVA pricks is discussed, though further research is required.

    Abstract Hard-to-heal wounds are a major cause of morbidity and/or mortality. Multiple aetiologies can be identified and wounds can be treated according to their aetiology and macroscopic appearance. However, evidence behind the wide range of locally applied treatments is weak, without clear guidelines available to treat a variety of wound aetiologies. We present the case of a 63-year-old male with hard-to-heal wounds not responding to standard topical treatment. No clear underlying aetiology could be found. Extensive contact allergies were diagnosed after multiple topical and systemic treatments had been applied. A full recovery was observed after stopping topical agents and treating the wounds with an alternative treatment based on epicutaneous test results.

    Abstract Survival in cases involving childhood malignancy is reaching nearly 80% in high-income countries, yet cancer remains one of the leading disease-related causes of death in children. In adult oncology the role of targeted therapies is established, but information regarding the use of these therapies in children is limited, largely because targeted therapies were developed in the context of adult pathologies. The few pediatric reports regarding crizotinib, an anaplastic lymphoma kinase (ALK) inhibitor, seem promising. This case of an 8-year-old male with an ALK-positive anaplastic large cell lymphoma highlights the challenges of treating children with crizotinib. Our experience with crizotinib was more challenging than described in the limited pediatric reports. Not only was the tumor response poorer than described in the reports, but a substantial amount of side-effects and practical difficulties, such as the method of administration and dosing, made management challenging. Many challenges for the use of targeted therapy in pediatric care currently persist. The limited research in pediatric populations leaves uncertainty regarding efficacy and short- and long-term side effects as well as practical difficulties. Despite a clear underlying biological rationale for certain targeted therapies, their contribution toward improving the outcome of childhood cancer remains largely unclear.

    Abstract The varicella-zoster virus (VZV) infects over 95% of the population. VZV reactivation causes herpes zoster (HZ), known as shingles, primarily affecting the elderly and immunocompromised individuals. However, HZ can also occur in otherwise healthy individuals. We analyzed the immune signature and risk profile in HZ patients using a genome-wide association study across different UK Biobank HZ cohorts. Additionally, we conducted one of the largest HZ HLA association studies to date, coupled with transcriptomic analysis of pathways underlying HZ susceptibility. Our findings highlight the significance of the MHC locus for HZ development, identifying five protective and four risk HLA alleles. This demonstrates that HZ susceptibility is largely governed by variations in the MHC. Furthermore, functional analyses revealed the upregulation of type I interferon and adaptive immune responses. These findings provide fresh molecular insights into the pathophysiology and the activation of innate and adaptive immune responses triggered by symptomatic VZV reactivation.

    Abstract Recently, a novel disorder coined VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome was identified in patients with adult-onset inflammatory syndromes, often accompanied by myelodysplastic syndrome1. All patients had myeloid lineage-restricted somatic mutations in UBA1 affecting the Met41 residue of the protein and resulting in decreased cellular ubiquitylation activity and hyperinflammation. We here describe the clinical disease course of two VEXAS syndrome patients with somatic UBA1 mutations of which one with a mild phenotype characterized by recurrent rash and symmetric polyarthritis, and another who was initially diagnosed with idiopathic multicentric Castleman disease and developed macrophage activation syndrome as a complication of the VEXAS syndrome. The latter patients was treated with anti-IL6 therapy (siltuximab) leading to a resolution of systemic symptoms and reduction of transfusion requirements.

    Abstract Accumulation of inorganic phosphate due to renal functional impairment contributes to the increased cardiovascular mortality observed in dialysis patients. Phosphate plays a causative role in the development of vascular calcification in renal failure; treatment with calcium-based phosphate binders and vitamin D can further increase the Ca x PO(4) product and add to the risk of ectopic mineralization. The new generation of calcium-free phosphate binders, sevelamer and lanthanum, can control hyperphosphatemia without adding to the patients calcium load. In this article, the metabolism of lanthanum carbonate and its effects in bone, liver and brain are discussed. Although lanthanum is a metal cation its effects are not comparable to those of aluminum. Indeed, in clinical studies no toxic effects of lanthanum have been reported after up to four years of follow-up. The bioavailability of lanthanum is extremely low. The effects observed in bone are due to phosphate depletion, with no signs of direct bone toxicity yet observed in rats or humans. The liver is the main route of excretion for lanthanum carbonate, which can be localized in the lysosomes of hepatocytes. No lanthanum could be detected in brain tissue.

    Abstract Lanthanum carbonate is a new phosphate binder that is poorly absorbed from the gastrointestinal tract and eliminated largely by the liver. After oral treatment, we and others had noticed 2-3 fold higher lanthanum levels in the livers of rats with chronic renal failure compared to rats with normal renal function. Here we studied the kinetics and tissue distribution, absorption, and subcellular localization of lanthanum in the liver using transmission electron microscopy, electron energy loss spectrometry, and X-ray fluorescence. We found that in the liver lanthanum was located in lysosomes and in the biliary canal but not in any other cellular organelles. This suggests that lanthanum is transported and eliminated by the liver via a transcellular, endosomal-lysosomal-biliary canicular transport route. Feeding rats with chronic renal failure orally with lanthanum resulted in a doubling of the liver levels compared to rats with normal renal function, but the serum levels were similar in both animal groups. These levels plateaued after 6 weeks at a concentration below 3 microg/g in both groups. When lanthanum was administered intravenously, thereby bypassing the gastrointestinal tract-portal vein pathway, no difference in liver levels was found between rats with and without renal failure. This suggests that there is an increased gastrointestinal permeability or absorption of oral lanthanum in uremia. Lanthanum levels in the brain and heart fluctuated near its detection limit with long-term treatment (20 weeks) having no effect on organ weight, liver enzyme activities, or liver histology. We suggest that the kinetics of lanthanum in the liver are consistent with a transcellular transport pathway, with higher levels in the liver of uremic rats due to higher intestinal absorption.
