Cutaneous Adverse Reactions Following Influenza Vaccination in Adults.

Objective: To review the literature on cutaneous reactions to the influenza vaccine in adults.

Data Sources: Authors systematically searched three databases: PubMed, MEDLINE, and EMBASE.

Study Selection: Case reports published between January 1, 1995 and December 31, 2020 that described a cutaneous reaction to any brand of the influenza vaccine in adults were included.

Diagnosing autism in low-income countries: Clinical record-based analysis in Sri Lanka.

Use of autism diagnosing standards in low-income countries (LICs) are restricted due to the high price and unavailability of trained health professionals. Furthermore, these standards are heavily skewed towards developed countries and LICs are underrepresented. Due to such constraints, many LICs use their own ways of assessing autism.

Paraneoplastic Pityriasis Rubra Pilaris Preceding Leukemia.

Pityriasis rubra pilaris (PRP) is a rare, chronic papulosquamous disorder that presents with scaling plaques, palmoplantar keratoderma, and keratotic follicular papules. Typically, there are distinctive unaffected areas referred to as "islands of sparing." Pityriasis rubra pilaris has been associated with various immunodeficient states and malignancies.

A Case of Indeterminate Cutaneous Dendritic Cell Tumors in the Setting of Chronic Myelomonocytic Leukemia.

Chronic myelomonocytic leukemia (CMML) is a rare hematopoietic stem cell neoplasm. Indeterminate dendritic cell neoplasm (IDCN) is an extraordinarily rare histiocytosis that may manifest secondarily to CMML. A 75-year-old man with a 2-year history of CMML presented for multiple cutaneous lesions on his head and neck.

High-Sensitive Detection and Quantitative Analysis of Thyroid-Stimulating Hormone Using Gold-Nanoshell-Based Lateral Flow Immunoassay Device.

Au nanoparticles (AuNPs) have been used as signal reporters in colorimetric lateral flow immunoassays (LFAs) for decades. However, it remains a major challenge to significantly improve the detection sensitivity of traditional LFAs due to the low brightness of AuNPs. As an alternative approach, we overcome this problem by utilizing 150 nm gold nanoshells (AuNSs) that were engineered by coating low-density silica nanoparticles with a thin layer of gold.
