A Narrative Review on 3-Dimensional Visualization Techniques in Neurosurgical Education, Simulation, and Planning.

Background: High-fidelity visualization of anatomical organs is crucial for neurosurgical education, simulation, and planning. This becomes much more important for minimally invasive neurosurgical procedures. Realistic anatomical visualization can allow resident surgeons to learn visual cues and orient themselves with the complex 3-dimensional (3D) anatomy.

Pathophysiology, diagnosis, and herbal medicine-based therapeutic implication of rheumatoid arthritis: an overview.

Rheumatoid arthritis (RA) stands as an autoimmune disorder characterized by chronic joint inflammation, resulting in profound physiological alterations within the body. Affecting approximately 0.4-1.

Rituximab Used for the Treatment of Nonuremic Calciphylaxis: A Complication of Prolonged Steroid Use in Lupus Nephritis.

Nonuremic calciphylaxis (NUC) is a rare and debilitating form of panniculitis. NUC is associated with a high mortality rate within the first year of diagnosis. Connective tissue diseases account for a small fraction of the reported cases.

Diabetes Mellitus Increases the Risk of Significant Hepatic Fibrosis in Patients With Non-alcoholic Fatty Liver Disease.

Background: Diabetes mellitus is associated with an increased risk of development of non-alcoholic fatty liver disease (NAFLD). However, the risk posed by diabetes mellitus in progression of liver disease is uncertain. This study compared the severity of hepatic fibrosis in patients with NAFLD with and without diabetes mellitus.

Bifascicular block in unexplained syncope is underrecognized and under-evaluated: A single-center audit of ESC guidelines adherence.

Background: The presence of bifascicular block on electrocardiography suggests that otherwise-unexplained syncope may be due to complete heart block. European Society of Cardiology (ESC) recommends investigating it with electrophysiology study (EPS). PPM is indicated if high-degree atrioventricular block is inducible.

Utilization of Rituximab for Refractory Rowell Syndrome.

Rowell syndrome describes the occurrence of erythema multiforme-like lesions in patients with cutaneous lesions of lupus erythematosus. The clinical picture of atypical erythema multiforme-like lesions, presence of chilblains, speckled ANA pattern, anti-Ro/SSA, or anti-La/SSB antibodies, and absence of infectious or pharmacologic triggers in a patient with systemic lupus erythematosus are some of the classic clinical and serologic features. Histopathologic and serologic findings can help differentiate this process from erythema multiforme.

Does withdrawal of immunosuppression in rheumatoid arthritis after SARS-CoV-2 infection increase the risk of vasculitis?

We describe a case of a 48-year-old woman who presented with acute respiratory failure due to diffuse alveolar haemorrhage and acute renal failure due to pauci-immune glomerulonephritis consistent with a new diagnosis of microscopic polyangiitis (MPA). The patient had a recent SARS-CoV-2 infection 6 weeks before MPA diagnosis and had stopped immunosuppression for her rheumatoid arthritis (RA) at that time. The patient was treated with pulse intravenous steroids, plasma exchange therapy and rituximab, which induced remission of her illness.

Patient Perception of Cardiovascular Risk in Rheumatoid Arthritis.

Objective: Patients with rheumatoid arthritis (RA) have higher incidence of cardiovascular diseases (CVDs) compared with age- and sex-matched controls. The objective of our study was to measure the knowledge of patients with RA about the association between their disease and cardiovascular (CV) risk and to measure the frequency of counseling by physicians based on patient report.

Methods: A telephone survey was conducted among patients with RA enrolled in the Consortium of Rheumatology Researchers of North America RA registry to collect data on medical and social history and on knowledge about CVD risk in RA and how they learned about that risk.

Efficacy of anakinra for idiopathic and non-idiopathic pericarditis refractory or intolerant to conventional therapy.

Background: Anakinra, a recombinant interleukin-1 receptor antagonist is effective in treatment of idiopathic recurrent pericarditis. However, its efficacy in non-idiopathic pericarditis (secondary to a diagnosed inflammatory condition, or other known etiology) is unclear. We evaluated the efficacy of anakinra in patients with non-idiopathic (secondary to a diagnosed inflammatory condition, or other known etiology) and idiopathic pericarditis, who were intolerant or refractory to conventional therapy (colchicine and corticosteroids).

An Unusual Presentation of Granulomatosis with Polyangiitis (GPA).

BACKGROUND This is a very interesting case of Granulomatosis with Polyangiitis (GPA) presenting with hand ischemia which rapidly evolved into dry gangrene from the involvement of digital arteries. GPA usually affects the small and medium sized blood vessels. GPA affecting muscular artery causing limb ischemia is a rare manifestation.

Total hip replacement as primary treatment of unstable intertrochanteric fractures in elderly patients.

Fifty-three patients with A2.2 and A2.3 intertrochanteric fracture according to the Muller classification were treated with total hip replacement between April 2000 and February 2004.
