Effects of low-level laser treatment on mouth dryness.

Unlabelled: Mouth dryness (MD) is usually followed by inadequate mechanical cleaning of the mouth and decrease in the levels of salivary antimicrobial proteins (including secretory immunoglobulin A (sIgA)). It is accompanied by difficulties during speaking and food swallowing, with an unpleasant taste, burning sensations in the mouth and higher susceptibility to oral diseases. Low-level laser treatment (LLLT) can intensify cell metabolism and its application on salivary glands could improve salivation.

Cyclosporine A or intravenous cyclophosphamide for lupus nephritis: the Cyclofa-Lune study.

Intravenous cyclophosphamide is considered to be the standard of care for the treatment of proliferative lupus nephritis. However, its use is limited by potentially severe toxic effects. Cyclosporine A has been suggested to be an efficient and safe treatment alternative to cyclophosphamide.

Salivary and serum levels of substance P, neurokinin A and calcitonin gene related peptide in burning mouth syndrome.

Background: Burning mouth syndrome (BMS) is an enigmatic condition with the aetiopathogenesis remaining largely obscure. However, a neuropathic basis for BMS continues to be an area of active clinical and research interest.

Aim: It is becoming increasingly evident that certain oral disorders may be modulated by imbalances in certain neuropeptides such as substance P (SP), neurokinin A (NKA) and calcitonin gene-related peptide (CGRP) therefore we measured SP, NKA and CGRP in the saliva and sera of BMS patients as well as controls.

MCP-1 -2518 A/G single nucleotide polymorphism in Slovak patients with systemic sclerosis.

Recent study in a group of German patients with SSc has implicated the SNP in the MCP-1 gene (-2518 A to G) as a factor of susceptibility to SSc. Reflecting the need for replication of genetic association studies, we investigated if this SNP is associated with SSc in another Caucasian population. MCP-1 -2518 A/G genotypes were determined using PCR-SSP in 46 SSc patients and in 449 healthy subjects, all unrelated and of Slovak (Slavonic) origin.
