Abstract
BACKGROUND Biopsy of the superficial temporal artery (STA) is central to the diagnosis of giant cell arteritis (GCA), but determining the ideal biopsy site along the course of the STA continues to be a challenge. Traditionally, the frontal branch or preauricular region of the STA is biopsied because of their accessibility, but biopsy at these locations can produce visible cosmetic defects and social disruption that can be distressing to patients, as well as increase the likelihood of adverse events such as injury to the facial nerve. The authors describe a surgical technique of biopsy of the parietal branch of the STA to improve the patient's perioperative and postoperative experience. METHODS In this retrospective review, 24 patients with clinical suspicion of GCA who underwent biopsy of the parietal branch of the STA were identified. Patients underwent mapping of the branches of the STA with Doppler ultrasound before the procedure. Biopsy of the parietal branch of the STA was conducted using a CO 2 laser. RESULTS Twenty-four patients underwent biopsy of the parietal branch of the STA. Two patients were diagnosed on histopathology with GCA. All patients tolerated the procedure well and without complications. CONCLUSION Application of preoperative Doppler ultrasound mapping, use of a CO 2 laser for incisions and hemostasis, and selection of the parietal branch allowed for improved cosmetic outcomes, no associated adverse events, and improved overall patient experience. The authors advocate biopsy of the parietal branch of the superficial temporal artery for the diagnosis of GCA in the absence of contraindications.

Abstract
Giant cell arteritis is a medical emergency because of the high risk of irreversible blindness and cerebrovascular accidents. While elevated inflammatory markers, temporal artery biopsy and modern imaging modalities are useful diagnostic aids, thorough history taking and clinical acumen still remain key elements in establishing a timely diagnosis. Glucocorticoids are the cornerstone of treatment but are associated with high relapse rates and side effects. Targeted biologic agents may open up new treatment approaches in the future.

Takayasu arteritis: a cohort of Italian patients and recent pathogenetic and therapeutic advances. Clin Exp Med 2020; 21:49-62.

Abstract
Takayasu arteritis (TAK) is a rare granulomatous vasculitis of unknown etiology that mainly affects the aorta and its major branches. The aim is to describe the clinical features, diagnostic procedures, pathogenesis, and management of TAK in a longitudinal cohort of patients recruited within a single region of southern Italy. The cohort included 43 patients who were diagnosed with TAK and followed up according to a standard protocol, in a collaboration between four university tertiary referral centers and a regional hospital. Clinical and imaging classification criteria were those established by the American College of Rheumatology. Thirty-five patients (81.4%) were female, and the mean age at disease onset was 32.6 (range 16–54) years. Angiographic assessment of the vascular involvement allowed disease classification in five different types. Clinical features ranged from constitutional symptoms in the early inflammatory stage of the disease to cardiovascular ischemic symptoms in the late, chronic stage. Noninvasive imaging techniques were employed to assess the extent and severity of the arterial wall damage and to monitor the clinical course and response to therapy. Medical treatment, based on pathogenetic insights into the roles of humoral and cell-mediated immune mechanisms, included glucocorticoids mostly combined with steroid-sparing immunosuppressive agents and, in patients with relapsing/refractory disease, biologic drugs. Significant clinical and angiographic differences have been detected in TAK patients from different geographic areas. Patients with life-threatening cardiovascular and neurologic manifestations as well as sight-threatening ophthalmologic signs and symptoms should be promptly diagnosed, properly treated, and closely followed up to avoid potentially severe consequences.

Abstract
To determine whether temporal artery biopsy (TABx) or Doppler ultrasound (US) of the temporal artery is the preferred confirmatory test for giant cell arteritis, an online survey of ophthalmologists and neurologists in North America, Europe and Israel was conducted in 2019; Canadian rheumatologists were also included. There were 406 survey participants with an estimated survey response rate of 18%. Ninety-four per cent of North American practitioners preferred TABx compared with 74% of their European counterparts. Two per cent of North American practitioners preferred Doppler US versus 24% of European physicians. Regional differences were statistically significant (p < .001).

Abstract
Cancer is a common malignant disease worldwide with an increasing mortality in recent years. Salvia miltiorrhiza, a well-known traditional Chinese medicine, has been used for the treatment of cardiovascular and cerebrovascular diseases for thousands of years. The liposoluble tanshinones in S. miltiorrhiza are important bioactive components and mainly include tanshinone IIA, dihydrodanshinone, tanshinone I, and cryptotanshinone. Previous studies showed that these four tanshinones exhibited distinct inhibitory effects on tumor cells through different molecular mechanisms in vitro and in vivo. The mechanisms mainly include the inhibition of tumor cell growth, metastasis, invasion, and angiogenesis, apoptosis induction, cell autophagy, and antitumor immunity, and so on. In this review, we describe the latest progress on the antitumor functions and mechanisms of these four tanshinones to provide a deeper understanding of the efficacy. In addition, the important role of tumor immunology is also reviewed.

Abstract
Purpose Giant cell arteritis (GCA), a chronic vasculitis of the large and medium-sized arteries, affects people >50 years of age. This study assessed the prevalence of visual manifestations and other clinical features at presentation in an Italian cohort of GCA patients. Recent advances in the pathophysiology, diagnosis, and therapy of GCA are also reviewed. Methods This retrospective, single-center study conducted by the ophthalmology and internal medicine clinics of one university recruited 56 patients from 2005 to 2016 and followed them for 11-54 months. Results Ocular involvement was diagnosed in 19 patients (33.9%), with permanent vision loss in 19.6% (7.1% of the cohort with bilateral vision loss). Arteritic anterior and posterior ischemic optic neuropathy were diagnosed in 11 patients (57.9%) and 1 patient (5.3%), respectively, cotton wool spots in 3 patients (15.8%), central retinal artery occlusion in 2 patients (10.5%), and anterior segment ischemia and multifocal choroidal ischemia in 1 patient each (5.3%). Polymyalgia rheumatica was associated with GCA in 44.6% of the patients. The most common extra-ocular manifestation was constitutional symptoms (82.1% of the patients). Large-vessel involvement, including of the ascending aorta, aortic arch, and left axillary artery, was diagnosed by magnetic resonance or computed tomography (CT) angiography and 18FDG positron emission/CT. Glucocorticoids (GCs) remain the standard-of-care worldwide, but methotrexate, provided as a steroid-sparing drug in 41% of the patients, resulted in earlier tapering, a lower cumulative dose of GCs, and a lower rate of relapse. Among the combinations of GCs and immunosuppressive drugs proposed to treat GCA, only tocilizumab has effectively induced and maintained disease remission. Conclusion According to our data and literature reports: a) GCA is a systemic disease; b) its diagnosis is expedited by the adjunct use of imaging techniques; c) insights into the pathogenesis of GCA may allow an improved, differentiated therapeutic approach.

Abstract
Recent epidemiological or immunopathological studies demonstrate the possible association between giant cell arteritis and infectious agents including Chlamydia pneumoniae. A 62-year-old Japanese man with type 1 diabetes mellitus developed biopsy-proven giant cell arteritis after acute upper respiratory infection. Serological examination indicated concurrent re-infection with C. pneumoniae. Clinical manifestations of the vasculitis subsided within a month without any immunosuppressive therapy, and no relapse was observed for the following 12 months. The natural history of this disease is unclear and spontaneous remission is rarely reported. The self-limiting nature of the infection could contribute to this phenomenon.

Abstract
PURPOSE To develop and validate neural network (NN) vs logistic regression (LR) diagnostic prediction models in patients with suspected giant cell arteritis (GCA). Design: Multicenter retrospective chart review. METHODS An audit of consecutive patients undergoing temporal artery biopsy (TABx) for suspected GCA was conducted at 14 international medical centers. The outcome variable was biopsy-proven GCA. The predictor variables were age, gender, headache, clinical temporal artery abnormality, jaw claudication, vision loss, diplopia, erythrocyte sedimentation rate, C-reactive protein, and platelet level. The data were divided into three groups to train, validate, and test the models. The NN model with the lowest false-negative rate was chosen. Internal and external validations were performed. RESULTS Of 1,833 patients who underwent TABx, there was complete information on 1,201 patients, 300 (25%) of whom had a positive TABx. On multivariable LR age, platelets, jaw claudication, vision loss, log C-reactive protein, log erythrocyte sedimentation rate, headache, and clinical temporal artery abnormality were statistically significant predictors of a positive TABx (P≤0.05). The area under the receiver operating characteristic curve/Hosmer-Lemeshow P for LR was 0.867 (95% CI, 0.794, 0.917)/0.119 vs NN 0.860 (95% CI, 0.786, 0.911)/0.805, with no statistically significant difference of the area under the curves (P=0.316). The misclassification rate/false-negative rate of LR was 20.6%/47.5% vs 18.1%/30.5% for NN. Missing data analysis did not change the results. CONCLUSION Statistical models can aid in the triage of patients with suspected GCA. Misclassification remains a concern, but cutoff values for 95% and 99% sensitivities are provided (https://goo.gl/THCnuU).

Abstract
OBJECTIVES To determine the role of the ocular pulse amplitude (OPA) from Pascal dynamic contour tonometry in predicting the temporal artery biopsy (TABx) result in patients with suspected giant cell arteritis (GCA). DESIGN Prospective validation study. PARTICIPANTS Adults aged 50 years or older who underwent TABx from March 2015 to April 2017. METHODS Subjects on high-dose glucocorticoids more than 14 days or without serology before glucocorticoid initiation were excluded. The OPA from both eyes was obtained and averaged just before TABx of the predominantly symptomatic side. The variables chosen for the a priori prediction model were age, average OPA, and C-reactive protein (CRP). Erythrocyte sedimentation rate (ESR), platelets, jaw claudication, and eye findings were also recorded. In this study, subjects with a negative biopsy were considered not to have GCA, and contralateral biopsy was performed if the clinical suspicion for GCA remained high. An external validation set (XVAL) was obtained. RESULTS Of 109 TABx, 19 were positive and 90 were negative. On univariate logistic regression, the average OPA had 0.60 odds for positive TABx (p = 0.03), with no statistically significant difference in age, sex, CRP, ESR, or jaw claudication. In suspected GCA, an OPA of 1 mm Hg had positive likelihood ratio 4.74 and negative likelihood ratio 0.87 for positive TABx. Multivariate regression of the prediction model using optimal mathematical transforms (inverse OPA, log CRP, age >65 years) had area under the receiver operating characteristic curve (AUROC) = 0.85 and AUROCXVAL = 0.81. CONCLUSIONS OPA is lower in subjects with biopsy-proven GCA and is a statistically significant predictor of GCA.

Abstract
A 71-year-old woman was admitted with fever, headache, and weight loss associated with elevated inflammatory markers. She developed acute bilateral ophthalmoplegia and asymmetrical ptosis, rapidly followed by anterior ischemic optic neuropathy. Although the first temporal artery biopsy was negative, contralateral temporal artery biopsy revealed features consistent with giant cell arteritis. Even while under steroid therapy, she died a few days later from myocardial infarction. Acute bilateral complete ophthalmoplegia is a rare presentation of a limited number of possible diseases. Among these, giant cell arteritis should be suspected in the appropriate clinical scenario.

Abstract
An 87-year-old woman presented 1 month after uneventful cataract surgery with ipsilateral corneal edema. She was diagnosed with pseudophakic bullous keratopathy and scheduled for endothelial transplantation. A few days later, however, she presented with bilateral corneal edema, dilated pupils, and further reduction of visual acuity. Neuro-ophthalmic evaluation disclosed a bilateral ocular ischemic syndrome causing complete visual loss. Temporal artery biopsy was consistent with giant cell arteritis. Corneal decompensation should be considered as a rare presentation of giant cell arteritis, a diagnosis that ophthalmologists should suspect in any case of unilateral or bilateral ocular ischemic syndrome.

Abstract
Giant cell arteritis (GCA) is the most common vasculitis of the elderly. The diagnosis can be challenging at times because of the limitation of the American Rheumatology Association (ARA) classification criteria and the significant proportion of biopsy-negative patients with GCA. We discuss the role of advanced imaging techniques, including positron emission tomography (PET) scanning, in establishing diagnosis and improved histopathology techniques to improve the sensitivity of temporal artery biopsy. There have been significant advances in the understanding of the pathogenesis of GCA, particularly the role of cytokine pathways such as the interleukins, IL-6-IL-17 axis, and the IL-12-interferon-γ axis and their implication for new therapies. We highlight that glucocorticoids remain the primary treatment for GCA, but recognize the risk of steroid-induced side effects. A number of pharmacotherapies to enable glucocorticoid dose reduction and prevent relapse have been studied. Early diagnosis and fast-track pathways have improved outcomes by encouraging adherence to evidence-based practice.
