Impact of Zinc Transport Mechanisms on Embryonic and Brain Development.

Nutrients 2022 Jun 17;14(12). Epub 2022 Jun 17.

Department of Pharmacology, Rutgers-Robert Wood Johnson Medical School, Piscataway, NJ 08854, USA.

The trace element zinc (Zn) binds to over ten percent of proteins in eukaryotic cells. Zn flexible chemistry allows it to regulate the activity of hundreds of enzymes and influence scores of metabolic processes in cells throughout the body. Deficiency of Zn in humans has a profound effect on development and in adults later in life, particularly in the brain, where Zn deficiency is linked to several neurological disorders. Read More

Line-field confocal optical coherence tomography (LC-OCT) as a new tool for non-invasive differential diagnosis of pustular skin disorders.

J Eur Acad Dermatol Venereol 2022 Jun 13. Epub 2022 Jun 13.

Dermatology Unit and Skin Bank, Department of Medical, Surgical and Neurosciences, Siena University Hospital, Siena, Italy.

Background: The spectrum of pustular skin disorders (PSD) is large and particularly challenging, including inflammatory, infectious and amicrobial diseases. Moreover, although pustules represent the unifying clinical feature, they can be absent or not fully developed in the early stage of the disease. The line-field confocal optical coherence tomography (LC-OCT) is a recently developed imaging technique able to perform a non-invasive, in vivo, examination of the epidermis and upper dermis, reaching very high image resolution and virtual histology.

[Viral exanthems in children].

Hautarzt 2022 Jun 25;73(6):452-460. Epub 2022 May 25.

Klinik für Dermatologie, Venerologie und Allergologie, Universitätsklinikum Schleswig-Holstein, Campus Kiel, Rosalind-Franklin-Str. 7, 24105, Kiel, Deutschland.

Viral and paraviral exanthems are the most common exanthems in children and are often the reason for a medical evaluation, especially in pediatric primary care and emergency rooms. Familiarity with the various eruptions is important for early diagnosis and patient management as well as minimizing the risk of infection. In this review, we present the newly described entities reactive infectious mucocutaneous eruptions (RIME) and the pediatric inflammatory multisystem syndrome (PIMS). Read More

Acrodermatitis continua of Hallopeau: historical perspectives and modern management.

Ital J Dermatol Venerol 2022 Apr;157(2):132-136

Rutgers New Jersey Medical School, Unit of Dermatology, Newark, NJ, USA -

Acrodermatitis continua of Hallopeau is a sterile pustular dermatosis primarily of the digits. Often considered a type of pustular psoriasis, it may be difficult to diagnose and even more difficult to treat. Initial involvement of a distal finger or toe may appear as erythema which should not be confused with the chilblains-like findings potentially associated with COVID-19 infection. Read More

Palmoplantar pustulosis and acrodermatitis continua of Hallopeau: demographic and clinical comparative study in a large multicentre cohort.

J Eur Acad Dermatol Venereol 2022 Apr 2. Epub 2022 Apr 2.

Masashi Akiyama

J Dermatol Sci 2022 Jan 25;105(1):11-17. Epub 2021 Nov 25.

Department of Dermatology, Nagoya University Graduate School of Medicine, Nagoya, Japan. Electronic address:

Pustular psoriasis is a chronic inflammatory skin disease characterized by erythematous plaques with sterile pustules. It includes the distinct clinical entities generalized pustular psoriasis (GPP), acrodermatitis continua of Hallopeau (ACH) and palmoplantar pustular psoriasis (PPPP). Recently clarified pathomechanisms of pustular psoriasis indicate that hyperactivation of the skin innate immunity, including of the IL-1/IL-36 axis, plays an important role in the pathogenesis of pustular psoriasis.

Diagnosis of Lyme Borreliosis With a Novel, Seminested Real-Time Polymerase Chain Reaction Targeting the 5S-23S Intergenic Spacer Region: Clinical Features, Histopathology, and Immunophenotype in 44 Patients.

Am J Dermatopathol 2022 May;44(5):338-347

Dermatologikum Hamburg, Hamburg, Germany; and.

Abstract: Lyme borreliosis (LB) is the most common tick-borne infection in Europe and North America. Polymerase chain reaction (PCR) is an important tool to confirm the diagnosis, but not always successful, especially when organisms are sparse. We developed a novel, seminested real-time PCR assay [target: 5S-23S intergenic spacer region (IGS)] and compared it with 3 well-established conventional PCR assays (IGS/OspA/real-time IGS) on 596 formalin-fixed, paraffin-embedded routine skin biopsies.

Zinc ionophores: chemistry and biological applications.

J Inorg Biochem 2022 03 9;228:111691. Epub 2021 Dec 9.

Dipartimento di Scienze Chimiche, Università degli Studi di Catania, v.le A. Doria 6, 95125 Catania, Italy. Electronic address:

Zinc can play a pathophysiological role in several diseases and can interfere in key processes of microbial growth. This evidence justifies the efforts in applying Zinc ionophores to restore Zinc homeostasis and treat bacterial/viral infections such as coronavirus diseases. Zinc ionophores increase the intracellular concentration of Zinc ions causing significant biological effects. Read More

Severe de novo pustular psoriasiform immune-related adverse event associated with nivolumab treatment for metastatic esophageal adenocarcinoma.

J Cutan Pathol 2022 May 22;49(5):472-481. Epub 2021 Dec 22.

Department of Pathology, The University of Texas MD Anderson Cancer Center, Houston, Texas, USA.

Breakthrough targeted therapies have produced significant improvements in survival for cancer patients, but have a propensity to cause cutaneous immune-related adverse events (irAEs). Psoriasiform irAEs, representing about 4% of dermatologic toxicities associated with immune checkpoint inhibitor (ICI) therapy, are usually mild, occur in older patients and present as an exacerbation of existing psoriasis after several doses of ICI therapy. We report a case of a 58-year-old woman with metastatic esophageal adenocarcinoma and no prior history of psoriasis who developed a pustular psoriasiform irAE, beginning 3 days after initiation of nivolumab and progressing to confluent erythroderma with pustules over 2 weeks despite topical steroid use.
