Evaluation of patient satisfaction with pharyngeal airway changes after orthognathic surgery in patients with Class III skeletal anomalies.

Purpose: The aims of our study were to determine the changes in the pharyngeal airway after treating patients with Class III malocclusion who received double jaw surgery, to determine the hard tissue and soft tissue parameters and the hyoid bone and tongue positions after surgery, to determine the changes to compare the pretreatment and post-treatment measurements of the patients in the double jaw group with the measurements of the control group patients, and to evaluate postoperative patient satisfaction. Materials and methods: The study included thirty-two Class III adult patients that received double jaw surgery and twenty-five Class I patients. Cephalometric records were taken before treatment (T1) and after treatment (T2). Results: After double jaw orthognathic surgery, there were statistically significant changes in all pharyngeal airway linear and areal parameters (p<0.001). There were significant superior and posterior movements of the tongue and hyoid bone post-surgery. The post-treatment analysis of the double jaw surgery group and control group were compared, with statistically significant differences in the mandibular dental parameters and pharyngeal airway measurements in patients in the double jaw surgery group. Conclusion: Despite the narrowings detected, high satisfaction scores were observed in the patient satisfaction questionnaire and the patients did not experience respiratory problems.

PUVA Induced Bullous Pemphigoid in a Patient with Mycosis Fungoides.

Background. Bullous pemphigoid is an autoimmune subepidermal blistering skin disease in which autoantibodies are directed against components of the basement membrane. The disease primarily affects the elderly people and in most of the patients inducing factors cannot be identified. Herein, we report a case of BP that occurred in a patient who was receiving PUVA therapy for the treatment of mycosis fungoides. Main Observation. A 26-year-old woman with mycosis fungoides developed blisters while receiving PUVA therapy. On physical examination tense bullae on the normal skin, remnants of blisters, and erosions were observed on her breasts, the chest wall, and the upper abdomen. Histopathological investigations revealed subepidermal blisters with eosinophilic infiltration and in direct immunofluorescence examination linear deposition of IgG along the basement membrane zone was observed. The diagnosis of bullous pemphigoid was also confirmed by ELISA and BIOCHIP mosaic-based indirect immunofluorescence test. Conclusions. PUVA therapy is an extremely rare physical factor capable of inducing bullous pemphigoid. So the development of blistering lesions during PUVA therapy may be suggestive sign of a bullous disease such as bullous pemphigoid and it should be excluded with proper clinical and laboratory approaches immediately after withdrawal of PUVA therapy.

Efficacy and safety of rituximab therapy in patients with pemphigus vulgaris: first report from Turkey.

BACKGROUND: Pemphigus vulgaris (PV) is a severe, chronic, and potentially life-threatening autoimmune blistering disease that affects the skin and mucous membranes. Rituximab is a monoclonal anti-CD20 antibody which has been used increasingly in the therapy of PV. METHODS: The present study sought to test the efficacy and safety of rituximab as an adjuvant therapy by retrospective analysis of clinical and immunological data for 29 patients with PV who were treated with rituximab between 2010 and 2015. Response to therapy, duration of clinical remission, serology of the response, and adverse effects of rituximab were evaluated. RESULTS: The mean ± standard deviation (SD) follow-up time was 17.48 ± 13.18 months. In all patients, findings showed either a decrease in antibody titers or that antibodies were completely undetectable after therapy. Rituximab use resulted in a significant reduction in steroid dosage during follow-up. At the end of the follow-up period, 26 patients (96.2%) had achieved complete remission with or without therapy (one patient had no follow-up and one patient had died, most probably as the result of a thromboembolic event). In 44.4% of patients, a clinical relapse occurred after a mean ± SD period of 13.1 ± 4.7 months after the initiation of rituximab therapy. Relapses were managed with additional infusions of rituximab. CONCLUSIONS: Rituximab is a beneficial and relatively safe adjuvant treatment for PV that facilitates prolonged clinical remission and has a significant steroid-sparing effect.

Serum soluble CD200 level was higher in patients with bullous pemphigoid during the active phase of the disease than for healthy individuals.

BACKGROUND: CD200 is a novel immunosuppressive molecule, existing both as cell membrane bound and as a soluble form in serum (sCD200), which acts to regulate inflammatory and acquired immune responses. Recently, our study group showed that sCD200 was found in serum and blister fluid in a patient with bullous pemphigoid and that anti-IgE therapy impacted those levels. We therefore planned this study to evaluate the soluble serum CD200 levels of bullous pemphigoid patients and compare it with that of healthy controls. We also analysed the association between the sCD200 levels and the clinical severity of the disease in bullous pemphigoid patients. METHODS: We investigated 5 consecutive patients with bullous pemphigoid, and 15 healthy controls were included in this study. Assessment of clinical examination and measurement of laboratory investigation were performed on the same day. Bullous pemphigoid patients were also assessed for Autoimmune Bullous Skin Disorder Intensity Score (ABSIS). Concentrations of anti-BP180 and soluble CD200 in the serum samples were quantified using ELISA kits. RESULTS: The serum soluble CD200 level was observed to be statistically significantly higher in patients with BP (77.6 +/- 15.7 pg/mL) compared with healthy controls (26.1 +/- 6.7 pg/mL), (p < 0.001). Nevertheless, there was no statistically significant correlation between serum soluble CD200 levels and clinical severity scores and Anti-BP180 values (p = 0.402, p = 0.395, respectively). However, there was a statistically significant correlation between ABSIS and Anti-BP180 levels in patients with BP (p = 0.036). CONCLUSIONS: CD200 might play a role in the immune response in the pathogenesis of bullous pemphigoid. However, we do not know the exact mechanism of CD200 in the disease initiation and/or progression.

There might be a role for CD200 in the pathogenesis of autoimmune and inflammatory skin disorders.

BACKGROUND: Soluble CD200 (sCD200) is a novel immuno-effective molecule, which acts to regulate inflammatory and acquired immune responses. Recently, our study group showed that sCD200 was present in serum and blister fluid in a patient with bullous pemphigoid and a patient with toxic epidermal necrolysis. We therefore planned this study to evaluate the sCD200 levels of autoimmune and inflammatory skin disorder patients and to compare them with that of healthy controls. MATERIAL/METHODS: Our study included 30 consecutive patients with psoriasis vulgaris, 15 with pemphigus vulgaris, and 15 healthy controls. Clinical examination and laboratory tests were performed on the same day. Psoriasis patients were also assessed with the Psoriasis Area and Severity Index (PASI) and pemphigus patients were assessed using the Pemphigus Disease Area Index (PDAI). Levels of sCD200 in the serum samples were quantified using ELISA kits. RESULTS: The serum sCD200 level was observed to be statistically significantly higher in patients with psoriasis vulgaris (96.7±15.8) compared to patients with pemphigus vulgaris (76.2±14.6), (p<0.001) and healthy controls (26.8±7.0) (p<0.001). The serum sCD200 levels were observed to be statistically significantly higher in patients with pemphigus vulgaris compared with that in healthy controls (p<0.001). In addition, there was a statistically significant correlation between serum sCD200 levels and PDAI (r=0.987, p=0.001). Nevertheless, there was no statistically significant correlation between serum sCD200 levels and PASI (r=0.154, p=0.407). CONCLUSIONS: sCD200 might play a role in immune response in the pathogenesis of autoimmune and inflammatory skin disorders. However, it remains to be fully elucidated how sCD200 can orchestrate inflammatory response in psoriasis and pemphigus.
