ABSTRACT
Burning mouth syndrome (BMS) is a complex chronic disorder characterized symptomatically by burning sensation mainly localized in the tongue with no specific lesions. Its etiology is not fully understood. Due to the persistent pain and unsatisfactory outcome of treatment, patients with high expectation when seeking medical advice easily feel discontent after treatment, which might cause medical dispute. This review introduces the epidemiology, manifestations, etiology, diagnosis, classification and treatment of BMS. The authors hope the current advances about BMS, mainly focus on the etiology of biological nerve and social psychology, may help the clinicians in treatment of BMS.
ABSTRACT
Mandibular osteomyelitis in a patient with psoriasis is an uncommonly clinical manifestation while there is an increasing number of reports and studies on involvements of stomatology in psoriasis, especially the death of a patient via or not via Allogeneicbone marrow transplantation has never been reported.To review the management and possible mechanisms in pathogenesis and treatment of psoriasis, as well as the relative involvements between stomatology and psoriasis the typical case with pictures and files is reviewed and literature is collected.Wekeepthe knowledge that psoriasis is either a primary keratinocyte disorder or an immunocyte-mediated chronic skin inflammatorydisease while bone marrow is under suspected for immunopathogenesis. More association of stomatologic conditions with psoriasis is emerging. Conclusively, allogeneicBMT and new knowledge are worth to be stressed by both stomatological and dermatological doctors. Further insights of this kind of auto immunologic disease are under its developing.
ABSTRACT
Objective To study the biological behaviors and effects of immunoglobulin-like transcript-4 (ILT4) expression in mononuclear cells on the prognosis of sepsis.Methods ILT4 +/+ (WT) and ILT4-knockout mice (ILT4-/-) male BALB/c mice were used for sepsis modeling using cecal ligation puncture (CLP).Flow cytometry was used to measure the levels of expression of ILT4 and major histocompatihility complex class Ⅱ molecules (MHC-Ⅱ) in mononuclear cells of peripheral blood 24 h after CLP.ELISA was used to measure the concentrations of interleukin-6 (IL-6) and serum tumor necrosis factor-alpha (TNF-α) in different groups of mice at 0 h,6 h,12 h,and 24 h after CLP to monitor the survival and prognosis over the course of 168 h.Results ILT4 was highly expressed in mononuclear cells of the peripheral blood of septic mice 24 h after CLP in comparison with that before CLP (1292.00 ± 143.70) vs.(193.50 ± 52.54),P ＜ 0.05.MHC-Ⅱ expression in mononuclear cells of the peripheral blood in ILT4-/-mice was significantly higher than that in WT mice (49.38 ± 5.66)％ vs.(24.25 ± 6.76) ％,P ＜ 0.05).Serum IL-6 was significantly elevated 24 h after CLP compared with that before CLP (470.75 ± 88.03) vs.(54.25 ± 20.04),P ＜ 0.05.The serum IL-6 concentration was much lower in ILT4-/-mice thanthatin MT mice (241.25 ± 45.10)vs.(470.75 ± 88.03),P ＜ 0.05;whereas,there was no significant difference in TNF-α expression between two groups of mice (50.88 ± 6.38) vs.(53.13 ± 5.49),P ＞ 0.05.The survival rate of ILT4-/-mice was significantly higher after CLP compared with WT mice (P ＜ 0.05).Conclusion The high level of ILT4 expression in mononuclear cells were observed in peripheral blood during sepsis and it was found to be associated with high serum IL-6 levels and low MHC-Ⅱ expression in mononuclear cells,leading to increased mortality.
