Background: Patients who have granulomatosis with polyangiitis (GPA, syn. M. Wegener) often develop an external nose deformity which may have devastating psychological effects. Therefore, reconstruction of nasal deformities by rhinoplasty may become necessary to achieve a normal appearance.
Objective Of Review: The aim of this systematic review was to investigate the efficacy and safety of surgical reconstruction in external nasal deformities and septal perforation in GPA patients.
Search Strategy: A systematic literature search with defined search terms was performed for scientific articles archived in the MEDLINE-Database up to 10 June 2016 (PubMed Advanced MEDLINE Search), describing management of cases or case series in GPA patients with saddle nose deformity and/or septal perforation.
Results: Eleven of 614 publications met the criteria for this analysis including 41 GPA patients undergoing external nasal reconstruction and/or septal reconstruction with a median follow-up of 2.6 years. Overall, saddle nose reconstruction in GPA patients is safe even if an increased rate of revision surgery has to be expected compared with individuals without GPA undergoing septorhinoplasty. Most implanted grafts were autografts of calvarial bone or costal cartilage. For septal perforation reconstruction, few studies were available. Therefore, based on the available data for surgical outcomes, it is impossible to make evidence-based recommendations. All included GPA patients had minimal or no local disease at the time of reconstructive surgery. Therefore, the relationship between disease activity and its impact on surgical outcomes remains unanswered. The potential impact of immune-modulating medications on increased complication rates and the impact of prophylactic antibiotics are unknown.
Conclusions: This study systematically reviews the efficacy and safety of surgical reconstruction of external nasal deformities in GPA patients for the first time. Saddle nose reconstruction in GPA patients with minimal or no local disease is a safe procedure despite an increased rate of revision surgery. Further research is required regarding the impact of antibiotic prophylaxis, immune-modulating therapy, long-term outcomes and functional outcomes measured with subjective and objective parameters.

Purpose: Therapeutic options for patients with brain metastases (BM) increase. While these lead to considerable survival effects in subgroups, there is limited knowledge about characteristics, prognosticators and treatment effects in patients with BM and short survival.
Methods: Patients with a survival time of ≤ 6 months (short-term survivors, STS), diagnosed with BM between 2009-2021 at a large tertiary cancer center were analysed.

Objective: To develop and validate a prognostic model for risk-stratified monitoring of 5-aminosalicylate nephrotoxicity.
Methods: This UK retrospective cohort study used data from the Clinical Practice Research Datalink Aurum and Gold for model development and validation respectively. It included adults newly diagnosed with inflammatory bowel disease and established on 5-aminosalicylic acid (5-ASA) treatment between 1 January 2007 and 31 December 2019.
Objective: The ADVOCATE trial demonstrated that treatment of active granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) with avacopan was noninferior in achieving remission at week 26 and superior for sustained remission at week 52 compared with a prednisone taper. This analysis of ADVOCATE evaluated the efficacy and safety of avacopan in patients with ear, nose, throat (ENT), or lung manifestations.
Methods: This post hoc analysis included patients enrolled in ADVOCATE with ENT or lung manifestations at baseline.

We report the case of a 75-year-old woman who presented with fever, right back pain, paresthesia in the right extremities, erythema, purpura, and nodules. She had previously initiated dialysis due to rapidly progressive glomerulonephritis and was transferred to our hospital. Imaging studies revealed multiple cerebral and splenic infarcts and hemorrhage encapsulating the right kidney, likely due to microaneurysms in multiple renal arteries.
