A case of cutaneous melanoma metastatic to the ciliary body and choroid with complete regression via systemic dual checkpoint inhibitor therapy.
BMC Ophthalmol
January 2025
Department of Surgery, St. Jude Children's Research Hospital, Memphis, TN, USA.
Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.
Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.

Ultraviolet (UV) irradiation is dangerous and can cause serious skin diseases if skin is excessively exposed to it. Thus, it is highly desirable for human health to monitor the UV radiation intensity. In this report, a flexible and stretchable dual-response UV radiation detector is reported by integrating UV-responsive color-switchable WO quantum dots (QDs) with an electrical hydrogel.

Hematology patients require central venous catheters for cancer treatment and nutrition, which increases their risk of intravascular device-associated bacteremia. In the absence of recent data, we investigated intravascular device-associated bacteremia in this specific context. A three-month surveillance was conducted annually in 27 hematology wards, using a protocol derived from the HAI-Net ICU ECDC protocol (2020-2024).

Many of the cells in mammalian tissues are in a reversible quiescent state; they are not dividing, but retain the ability to proliferate in response to extracellular signals. Quiescence relies on the activities of transcription factors (TFs) that orchestrate the repression of genes that promote proliferation and establish a quiescence-specific gene expression program. Here we discuss how the coordinated activities of TFs in different quiescent stem cells and differentiated cells maintain reversible cell cycle arrest and establish cell-protective signalling pathways.

Sci Rep

Department of Dermatology, Gunma University Graduate School of Medicine, 3-39-22, Showa, Maebashi, Gunma, 371-8511, Japan.
Systemic sclerosis (SSc) is an idiopathic systemic connective tissue disorder characterized by fibrosis of the skin and internal organs, with growing interest in the imbalance between Th17 cells and regulatory T cells (Tregs) in the disease's pathogenesis. Heligmosomoides polygyrus (Hp), a natural intestinal parasite of mice, is known to induce Tregs in the host. We aimed to investigate the effects of Hp-induced Tregs on bleomycin-induced dermal fibrosis and clarify the role of the Th17/Treg balance in SSc fibrosis.
