Behcet disease combined with Sjogren syndrome: A unique case report and literature review.

RATIONALE: Behcet disease(BD) and Sjogren syndrome(SS) are separate conditions that rarely concomitantly affect an individual. In theory,mild symptoms of patients with BD or SS are easy to igore and,thus,remain undiagnosed. There,it is reasonable to believe there may be some clinical cases of combined diseases that go undiscovered and which needs to be taken seriously. In addition,it has been suggested that herpes simplex virus(HSV) types 1 and 2 are associated with BD,but have not been shown to be correlated to the direct pathogenesis of BD. The role of HSV in BD needs more research and attention. PATIENT CONCERNS: Here,we report a young woman who had both BD and SS. The first symptom of the disease was fever. However,the HSV type 1 IgG and HSV type 2 IgM antibody results were positive in our case and,which rendered this case unique. DIAGNOSES: BD and SS concomitantly affect the individual,and BD was the acute type. INTERVENTIONS: IV methylprednisolone was used for 9 days and then oral glucocorticoids was used to instead,and the treatment works very well. OUTCOMES: BD and SS can concomitantly affect an individual,and we believe that HSV-2 may be directly related to the pathogenesis of BD. The nature of BD as an auto-inflammatory disorder, autoimmune disorder, or both, is controversial. If we can find more patients who combined affected these two disease, it might helpful for us to understand the nature of BD. LESSONS: For patients with clinical diagnosis of BD or SS,we need to be alert that it may combinded the other disease. Long term follow up and detailed inspection are important means to avoid undiscovered.

Oil-Water Separation of Electrospun Cellulose Triacetate Nanofiber Membranes Modified by Electrophoretically Deposited TiO2/Graphene Oxide.

Recycled waste industrial cellulose triacetate (TAC) film, which is one of the key materials in polarizers, was used to produce nanofiber membranes by electrospinning and synergistic assembly with graphene oxide (GO) and titanium dioxide (TiO2) for oil-water separation. In this study, GO and TiO2 coated by an electrophoretic deposition method introduced super hydrophilicity onto the recycled TAC (rTAC) membrane, with enhanced water permeability. The results indicate that when the outermost TiO2 layer of an asymmetric composite fiber membrane is exposed to ultraviolet irradiation; the hydrophilicity of the hydrophilic layer is more effectively promoted. Moreover, this coating could efficiently repel oil, and demonstrated robust self-cleaning performance during the cycle test, with the aid of the photocatalytic properties of TiO2. The rTAC membrane of networked hydrophobic fibers could also increase the speed of the filtrate flow and the water flux of the oil-water emulsion. The permeate carbon concentration in the water was analyzed using a total organic carbon analyzer. Incorporation of TiO2/GO onto the rTAC membrane contributed greatly towards enhanced membrane hydrophilicity and antifouling performance. Therefore, the novel TiO2/GO/rTAC asymmetric composite fiber has promise for applications in oil-water separation.

Chronic myeloid leukemia following repeated diagnostic X-ray exposure for the treatment of recurrent spontaneous pneumothorax in a patient with ankylosing spondylitis: A case report and literature review.

Previous studies have indicated that X-ray irradiation may increase the risk of chronic myeloid leukemia (CML), and the incidence of spontaneous pneumothorax in patients with ankylosing spondylitis (AS) is higher than in the general population. Patients with AS usually develop spontaneous pneumothorax several years after the diagnosis of AS. The present study reports the unusual case and complicated clinical history of a 29-year-old man with recurrent pneumothorax and AS, who developed CML following repeated exposure to low doses of radiation via diagnostic X-rays and chest computed tomography imaging. Pneumothorax was diagnosed prior to AS in this patient; the present case report highlights the importance of recognizing AS as a possible underlying cause of recurrent spontaneous pneumothorax. Patients with AS may be more sensitive to injury via X-ray-derived radiation, and even small diagnostic doses may be associated with CML. Diagnostic X-ray exposure should therefore be limited to reduce the risk of radiation-associated malignancies, including CML, particularly in patients with AS.

Chronic myeloid leukaemia following repeated exposure to chest radiography and computed tomography in a patient with pneumothorax: A case report and literature review.

It is well known that radioactive rays may cause damage to the human body. Progress in modern medicine has led to an increased risk of therapeutic and diagnostic radiation exposure of patients. Although clear evidence of a radiation dose-dependent risk of chronic myeloid leukaemia, particularly for patients exposed to radiation at a young age, has been established, it is not known whether radiation exposure during diagnostic imaging also increases the risk of cancer. The present study reports the case of a patient who underwent several diagnostic imaging tests (including repeated chest radiography and computed tomography) for recurrent pneumothorax. At around one year subsequent to these tests, the patient was diagnosed with chronic myeloid leukaemia. The patient exhibited an increase in white blood cell count over time, and a bone marrow smear test showed a myeloid/erythroid ratio of 13.9:1. In addition, the qualitative breakpoint cluster region (BCR)/Abelson (ABL) gene test revealed positive results for BCR/ABL fusion (p210). Based on the data reported in the current case, research aimed at elucidating the potential risks associated with diagnostic radiation is urgently required. It is crucial that medical professionals consider the potential harmful side effects of diagnostic radiation when ordering radiation-based diagnostic imaging examinations.
