Henoch-Schönlein purpura (HSP) is a small-vessel vasculitis that has been extensively studied in children, but little is known about its natural history in adults. There is no consensus regarding the treatment of glucocorticosteroids use for HSP. The efficacy of glucocorticoid for preventing from severe complications or relapse is also controversial in HSP. ⋯ Our patient has a good response to glucocorticoid. Glucocorticosteroids may be effective for the treatment of HSP.

Retinal arterial macroaneurysms (RAMs) develop as outpouchings of the arterial wall that is weakened by arteriosclerosis. The traditional treatment of RAMs comprises observation, focal laser photocoagulation, or surgery. Recently, intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs has been announced as an effective therapy for fovea-threatening RAMs and quickly improve visual acuity and central retinal thickness (CRT). ⋯ A systematic work-up for hypertension and arteriosclerotic disease could be considered the recommended procedure once RAM has been diagnosed. With better final visual acuity, significant visual improvements, and fast reduction of CRT observed in patients with fovea-threatening RAMs receiving anti-VEGF intravitreal injections, intravitreal anti-VEGF was considered an effective therapy for complicated RAM. During the follow-up period, the majority of RAM eyes had good maintenance of visual function even with foveal complications.

Peripheral arterial diseases (PADs) is defined as a systemic arterial disorders involving the lower extremity arteries, iliac, and carotid, which is developed more common in patients with chronic kidney disease (CKD) than individual with normal renal function. Concurrence of mesenteric artery disease and lower extremity artery disease (LEAD) is rare. The presence of PADs in patients receiving hemodialysis leads to a dramatic increase in risk of cardiovascular mortality. However, the early diagnosis of PADs in patient with CKD remains a challenge to nephrologists, which adds an adverse effect on prognosis. ⋯ The incidence of PADs is higher in dialysis patients due to a unique set of biochemical and endocrine abnormalities. As there is a high uremic status and PADs burden in patients with hemodialysis, the short term risk of cardiovascular disesase mortality markedly increases. There is a need for nephrologists and cardiovascular physicians to identify these patients and then provide early and proper treatment.

Observational Study
Chromosomal microarray analysis for the detection of chromosome abnormalities in fetuses with echogenic intracardiac focus in women without high-risk factors.
To investigate the association between pathogenic copy number variants (p-CNVs) and abnormal karyotypes detected by chromosomal microarray analysis (CMA) and echogenic intracardiac focus (EIF). This was a retrospective study of fetuses with EIF with CMA data at the Prenatal Diagnosis Center of the West China Second University Hospital of Sichuan University between September 2014 and May 2017. Fetuses were assigned to the isolated EIF and non-isolated EIF groups according to the presence of other ultrasound abnormalities. ⋯ In pregnant women without high-risk factors for chromosomal abnormalities, ultrasound abnormalities, including EIF, could be an indication for CMA. Ultrasound abnormalities (including EIF) and chromosome abnormality could indicate a high risk of CHD. The presence of EIF and at least another ultrasound abnormality could indicate a high risk of trisomy 21.

Recently, the American Joint Committee on Cancer (AJCC) 8th staging manual stipulated the World Health Organization (WHO) G3 pancreatic neuroendocrine carcinomas (p-NECs) should all be classified by the system for pancreatic exocrine adenocarcinomas, which had ignored the heterogeneity of G3 p-NECs. We focused on demonstrating whether the heterogeneous subgroups of G3 p-NECs would influence the accurate application of AJCC 8th staging systems. G3 p-NECs were divided into well-differentiated and poorly-differentiated subgroups, whose clinical features and overall survival (OS) were compared. ⋯ The system for G1/G2 p-NETs could significantly differentiate the survival differences between each new stage of well-differentiated G3 p-NECs (P < .05), while comparisons of survivals between Stage II with Stage III or Stage III with Stage IV by the system for G3 p-NECs were not statistically different (P = .334, P = .073; respectively). G3 p-NECs were heterogeneous with well-differentiated and poorly-differentiated subgroups. Both AJCC 8th staging systems proposed for all G3 p-NECs and G1/G2 p-NETs were practical for well-differentiated G3 p-NECs, while the one originally applied to G1/G2 p-NETs appeared to be superior in performance due to its better prognostic stratification and more accurate predicting ability.
