The cutaneous focal mucinoses are a group of connective tissue disorders characterized by deposition of mucin found either focally or diffusely in the dermis. A 47-year-old woman presented with asymptomatic flesh-colored papules on the neck, inguinal area, intergluteal area, vulvar area, and extremities of 5 months' duration. There was no history of preceding trauma or insect bites. The patient had undergone a subtotal thyroidectomy 21 years prior but had not used any thyroid medication before she was referred to our clinic. Thyroid ultrasonography was consistent with Hashimoto thyroiditis. During dermatologic examination, flesh-colored, well-defined, smooth papules that measured approximately 1.5 x 1 cm in size on the genital region, fingers, face, and scalp were seen. Histopathologic examination of a lesional biopsy revealed no abnormalities in the epidermis. Alcian blue staining showed that abundant deposits of dermal mucin had replaced collagen in the dermis.

Background: Autoimmune thyroid diseases (AITD) and allergic rhinitis (AR) are prevalent conditions; however, limited research has investigated their association. This study aimed to evaluate whether AR can be considered a risk factor for developing AITD.
Methods: A retrospective cohort study analyzed the records of AITD patients who visited Alexandria University Students Hospital between January 2017 and December 2021.

Chronic complete spinal cord injury (SCI) is difficult to treat because of scar formation and cavitary lesions. While human iPS cell-derived neural stem/progenitor cell (hNS/PC) therapy shows promise, its efficacy is limited without the structural support needed to address cavitary lesions. Our study investigated a combined approach involving surgical scar resection, decellularized extracellular matrix (dECM) hydrogel as a scaffold, and hNS/PC transplantation.

The management of papillary thyroid carcinoma (PTC) concurrent with Hashimoto's thyroiditis (HT) lacks standardized guidelines, especially concerning surgical strategies. This study aimed to compare unilateral thyroidectomy (UT) with total thyroidectomy (TT) in PTC-HT patients to optimize clinical management and improve postoperative outcomes. This retrospective study included PTC-HT patients undergoing thyroid surgery at a tertiary academic medical institution from January 2018 to August 2023.

Background: Evans syndrome is a rare disorder characterized by the simultaneous or sequential combination of autoimmune hemolytic anemia and immunological thrombocytopenia, together with a positive direct antiglobulin test. This syndrome, which can be primary or secondary, is a rare initial manifestation of autoimmune diseases, notably systemic lupus erythematosus, with 1.7-2.

Background: Previous studies report that Hashimoto's thyroiditis (HT) may be associated with non-ischemic cardiomyopathy (NICM); However, the causal relationship remains to be elucidated. Here, we aimed to investigate the causal relationship between HT and NICM through Mendelian randomization (MR) and explore the potential mediating role of inflammatory cytokines within this association.
Methods: The bidirectional two-sample MR, multivariable MR and mediation MR analyses were conducted based on genome-wide association study summary datasets, and MR results were further supported by multiple sensitivity analysis methods.
