Therapeutic strategies and outcomes in neuropsychiatric systemic lupus erythematosus: an international multicentre retrospective study.

Objectives: The management of neuropsychiatric systemic lupus erythematosus (NPSLE) poses considerable challenges due to limited clinical trials. Therapeutic decisions are customized based on suspected pathogenic mechanisms and symptoms severity. This study aimed to investigate therapeutic strategies and disease outcome for patients with NPSLE experiencing their first neuropsychiatric (NP) manifestation.

Q-uestioning the Diagnosis: An Educational Case Report.

Rationale: Q fever is a zoonotic infection that may lead to acute or long-term renal injury. Given its rare incidence, Q fever is not often considered on the initial differential diagnosis for glomerular disease which can lead to delays in treatment. This case highlights the importance of avoiding early diagnostic closure and revisiting the differential diagnosis in the setting of an atypical clinical presentation or response to treatment.

Positron Emission Tomography/Computerized Tomography in Newly Diagnosed Patients with Giant Cell Arteritis Who Are Taking Glucocorticoids.

Objective: Large vessel uptake on positron emission tomography/computerized tomography (PET/CT) supports the diagnosis of giant cell arteritis (GCA). Its value, however, in patients without arteritis on temporal artery biopsy and in those receiving glucocorticoids remains unknown. We compared PET/CT results in GCA patients with positive (TAB+) and negative temporal artery biopsies (TAB-), and controls.

Validity of the Italian algorithm for the attribution of neuropsychiatric events in systemic lupus erythematosus: a retrospective multicentre international diagnostic cohort study.

Objective: To validate the Italian algorithm of attribution of neuropsychiatric (NP) events to systemic lupus erythematosus (SLE) in an external international cohort of patients with SLE.

Methods: A retrospective cohort diagnostic accuracy design was followed. SLE patients attending three tertiary care lupus clinics, with one or more NP events, were included.

Application of the International Germ Cell Consensus Classification to the Nova Scotia population of patients with germ cell tumours.

Background: The International Germ Cell Consensus Classification (IGCCC) is the internationally accepted, clinically based prognostic classification used to assist in the management and research of metastatic germ cell tumours (GCTs). The goal of this study was to determine whether the IGCCC is applicable to a population-based cohort.

Methods: We completed a retrospective chart review of patients who received diagnoses of GCT in Nova Scotia between 1984 and 2004 and who received treatment with platin-based chemotherapy for metastatic disease.
