Retinal Vasculitis as a Rare Presentation of Microscopic Polyangiitis.

Microscopic polyangiitis (MPA) is a rare, autoimmune, small-vessel vasculitis usually described with the presence of perinuclear antineutrophil cytoplasmic antibodies (p-ANCA). It encompasses a broad spectrum of clinical features, including fatigue, weight loss, fever, arthralgia, skin lesions, and involvement of the lungs or kidneys. Ocular manifestations, however, are extremely rare.

Mesenteric Panniculitis in Sjögren's Syndrome: A New Systemic Manifestation to Consider?

Unlabelled: The association between mesenteric panniculitis and Sjögren's syndrome, although rare, is starting to be recognized. Usually, mesenteric panniculitis is symptomatic, presenting with either general or gastrointestinal symptoms. Sjögren's syndrome is an autoimmune disease that typically affects secretory glands, but may have serious systemic involvement.

Chlorpyrifos-Induced Delayed Neurotoxicity with A Rare Presentation of Flaccid Quadriplegia: A Diagnostic Challenge.

Unlabelled: Chlorpyrifos is an organophosphate compound recognized as causing acute toxicity. However, organophosphate-induced delayed polyneuropathy (OPIDP), although rare, has also been described. We describe an unusual presentation of OPIDP with flaccid quadriplegia progressing to a locked-in-like syndrome, 30 days after a 60-year-old man voluntarily ingested chlorpyrifos.

Rapidly Progressive Encephalopathy: Initial Diagnosis of Creutzfeldt Jakob Disease in an Intensive Care Unit.

Unlabelled: Creutzfeldt-Jakob disease (CJD) is a rare, incurable and fatal condition that can only be confirmed through neuropathological investigation, such as brain biopsy or post-mortem study. However, a probable diagnosis can be made using clinical criteria. CJD manifests as rapidly progressive dementia with myoclonus and to a lesser extent visual impairment and cerebellar and pyramidal/extrapyramidal signs.
