Article Abstract

To improve sensitivity of the analysis of axon reflex flare reaction, the authors used a laser Doppler scanner and analyzed flare intensity and size induced by histamine iontophoresis simultaneously at the foot and thigh in patients with small-fiber neuropathy (n = 10) and controls (n = 9). Flare size, but not laser Doppler flux, clearly distinguished patients from controls at both locations (p < 0.01) and may be useful for evaluation of small-fiber neuropathies.

Iodoform, a halogenated organic compound, has been a cornerstone in surgical practice due to its potent antiseptic and antimicrobial properties. This comprehensive review examines the historical evolution, mechanism of action, clinical applications, and safety profile of iodoform across various surgical disciplines. Historically significant formulations like Whitehead's varnish and bismuth iodoform paraffin paste (BIPP) demonstrated remarkable efficacy in wound healing during the late 19th and early 20th centuries.

Lepra reactions are acute episodic inflammatory reactions that occur during illness due to abrupt changes in the body's immunological response against Mycobacterium leprae. These are of two types, type 1 and type 2. Type 2 reaction is also called Erythema Nodosum Leprosum (ENL).

Introduction/objectives: Genetic variations could explain individual responses to drugs. This case-control study aimed to investigate the association between the multidrug resistance 1 (MDR1) gene exonic single nucleotide variants (SNVs), rs1128503/C1236T and rs1045642/C3435T, and the response to intravenous methylprednisolone in Egyptian patients with active systemic lupus erythematosus (SLE).

Method: Real-time polymerase chain reaction was used.
