Case of coincident severe acne and psoriasis in AIDS patient successfully treated with antiretroviral therapy

Cutaneous disorders remain a major problem in HIV‐infected patients, even under antiretroviral therapy (ART). Patients at any stage of HIV/AIDS may suffer from skin lesions. Acnes and psoriasis are both common chronic and inflammatory skin diseases, and the treatment becomes more challenging and complex when combined with HIV infection. Whether the incidence and severity of acne and psoriasis are related to HIV infection is still controversial. Here, we report a rare case of an AIDS patient who developed severe acne along with psoriasis. The patient had initially received multiple systemic and topical antipsoriatic and anti‐acne treatments which failed. Ultimately, he achieved dramatic clinical improvement after initiation of ART for main treatment. An 8‐year follow up demonstrated that the patient has been free of symptoms of both psoriasis and acne till now.     

Pointwise SAR image change detection using stereo-graph cuts with spatio-temporal information

In this letter, a pointwise approach using stereo-graph cuts (SGC) with spatio-temporal information is proposed for synthetic aperture radar (SAR) image change detection. The SGC is based on stereo-graph, which is designed to connect the local maximum pixels on two SAR images and can be used to capture the spatio-temporal information. With the support of stereo-graph, a novel SGC energy function is presented to quantify the spatio-temporal information and implicitly measure the difference information between the SAR images. Therefore, the change detection results can be obtained by minimizing the energy function with graph cuts technology. Experimental results on real SAR datasets confirm the validity of the proposed approach in which SGC and spatio-temporal information offer great contributions on improving the robustness and accuracy of detection.     

Human urinary kallidinogenase in treating acute ischemic stroke patients: analyses of pooled data from a randomized double-blind placebo-controlled phase IIb and phase III clinical trial

ABSTRACT

Objectives: Intravenous thrombolysis and thrombectomy are recommended for patients whose stroke onsets are within first 6 h, and very few options are available for patients whose stroke onset is more than 6 h, which includes most ischemic stroke patients. Human urinary kallidinogenase (HUK) showed potential clinical benefits in acute ischemic stroke patients. This study aims to investigate the safety and clinical benefits of HUK in ischemic stroke patients.

Patients and methods: Patients were recruited for a multicenter double-blind, placebo-controlled phase II b and phase III trial. Neurophysiological outcomes were assessed by the European Stroke Scale (ESS) and the functional outcomes were assessed by the activity of daily living scale (ADL). Safety was monitored by recording adverse events.

Results: The improvements in ESS scores and ADL scores in the HUK group were significantly greater than that in patients receiving placebo. Furthermore, HUK treatment was also associated with a lower rate of disable, according to ADL. HUK-related adverse events occurred at a low rate, in 1.73% of HUK-treated patients.

Conclusion: HUK is safe and provides potential clinical benefits as a treatment for acute ischemic stroke. Further large post-marketing observational studies are needed.     

成人后孟氏骨折与经尺骨近端骨折后脱位的鉴别与治疗

经典孟氏骨折的定义是尺骨骨折伴上尺桡关节脱位,如合并桡骨头后脱位,即肱桡关节后脱位时,称为后孟氏骨折。而对于不伴有上尺桡关节脱位者,不应笼统称为后孟氏骨折,可称为经尺骨近端骨折后脱位。对于伴有上尺桡关节脱位后孟氏骨折,临床相对少见,其冠突骨折通常粉碎,上尺桡关节遭到破坏,环状韧带及骨间膜损伤,治疗时在恢复骨性结构及处理外侧韧带复合体后,还须关注与处理上尺桡关节的稳定,预后疗效不确定。而经尺骨近端骨折后脱位临床相对多见,其冠突骨折块通常完整,环状韧带及骨间膜完好,在治疗上以恢复骨性结构为主,同时处理肘关节外侧韧带复合体,预后效果好。通过解剖基础、影像学特征、损伤特点、治疗方法及预后等方面鉴别和区分后孟氏骨折与经尺骨近端骨折后脱位。     

化痰祛瘀汤治疗颈动脉易损斑块痰瘀互结证临床研究

In vivo cutaneous antinuclear antibody positivity in palisaded neutrophilic and granulomatous dermatitis

Palisaded neutrophilic and granulomatous dermatitis (PNGD) is commonly associated with underlying systemic inflammatory and neoplastic diseases, infections, and drug reactions. In vivo cutaneous antinuclear antibodies (ANA) have been described in skin biopsies from patients with known autoimmune disorders, but not previously reported in the setting of PNGD. We present two patients with systemic lupus erythematosus (SLE) and histopathologically confirmed PNGD. Direct immunofluorescence (DIF) studies revealed in vivo cutaneous ANA positivity in both patients. DIF findings in the skin mirrored serum autoantibody results. ANA positivity in skin specimens is reported as highly predictive of systemic connective tissue diseases (SCTD), although specific testing is not currently recommended as part of the laboratory work-up or diagnostic criteria for these disorders. In this case report, positive ANA results in skin biopsies of PNGD reflect the serological findings and clinical evidence of SLE in both patients. In vivo cutaneous ANA positivity is an interesting and supportive finding in PNGD in the setting of SCTD.     

The effects and acceptability of different exercise modes on glycemic control in type 2 diabetes mellitus: A protocol for systematic review and network meta-analysis

Introduction:Exercise has been believed to have positive effects on blood glucose control in patients with type 2 diabetes mellitus. However, few medical evidences have been found to ascertain which type of exercise has the best effect on blood glucose control in diabetes and which type of exercise is more acceptable. The purpose of this study is to compare the effects and acceptability of different exercise modes on glycemic control in type 2 diabetes patients by using systematic review and network meta-analysis.Methods and analysis:Relevant randomized controlled trial studies will be searched from PubMed, EMbase, CochraneCENTRAL, CNKI, VIP, and Chinese medical paper libraries. Primary outcome indicators: glycosylated hemoglobin and dropout rate of the research (number of dropouts/numbers of initially enrolled subjects). Secondary outcome measures: fasting blood glucose, body weight, total cholesterol (TC), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol, triglycerides (TG), diastolic pressure, systolic pressure (SBP). Two reviewers are arranged to screen Title, Abstract, and then review full text to further extract data. Standard meta-analysis and network meta-analysis of the data are performed afterward. Methodological quality assessment is planned to be conducted using Cochrane risk of bias tool. The outcome will be analyzed statistically according to Bayesian analysis methods. After that, subgroup analysis is conducted on the duration of intervention, whether there is supervision of intervention, frequency of intervention per week, age, gender, and medication use.Trial registration number:PROSPERO CRD42020175181Discussion:The systematic review and network meta-analysis include evidence of the impact of different exercise modes on blood glucose control in type 2 diabetes mellitus. There are 2 innovative points in this study. One is to conduct a classified study on exercise in as much detail as possible, and the other is to study the acceptability of different exercise modes. The network meta-analysis will reduce the uncertainty of intervention and enable clinicians, sports practitioners, and patients to choose more effective and suitable exercise methods.Ethics and dissemination:The findings of the study will be disseminated through publications in peer-reviewed journals and scientific conferences and symposia. Further, no ethical approval is required in this study.
