What a wonderful experience at #ARANZRA24 . It was filled with so much learning and fantastic interactions! Also a huge thank you to 2 very inspirational mentors of mine, Dr Andrew Foote and Dr Mueed Mian for guiding me through my research projects. @AusRheum

20% of older population may have monoclonal gammopathy of unknown significance, and often after a period of surveillance they do not progress to paraproteinaemias (ie Waldenstrom's, myeloma, MGCS)

@DoctorMed0 Grave's disease

The TRIAD is called...

Ornithine Transcarbamylase deficiency (OTC) is the most common cause of urea-cycle disorder, leading to excessive ammonia and cerebral glutamine presenting with encephalopathy. Ix: Plasma amino acids and acylcarnitines + urine amino acid Rx: Plasma nitrogen scavengers + arginine/carnithine

Vomiting can cause arrhythmia due to: 1) Hypok from loss of K via H-K ATPase in kidneys to counteract metabolic alkalosis 2) Extracellular shift of H with intracellular shift of K This leads to more negative resting membrane of the cardiac myocytes leading to hyperpolarization and delayed conduction ie U wave and TdP

@ZahoorAhmed1450 Vancomycin

Which antibiotic is associated with “red man syndrome”? A) Vancomycin B) Penicillin C) Azithromycin D) Ciprofloxacin

A middle-aged woman with long-standing rheumatoid arthritis on methotrexate, a TNF inhibitor, and low-dose steroids develops an acutely swollen knee. She is afebrile. Synovial fluid analysis shows a WCC of 60,000, and Gram stain is negative. What is the most appropriate next step? A) Increase oral steroids B) Repeat aspiration + intra-articular steroid C) Switch biologic therapy D) Change csDMARD E) Start IV antibiotics

Anti-resorptives for osteoporosis: - bisphosphonates - denosumab - SERM - hormonal therapy - calcitonin (hardly ever used) Anabolic agents for osteoporosis: - Teriparatide - Romosozumab

@IhabFathiSulima Vitiligo and psoriasis

Two autoimmune diseases. What are they?

High yield dermatology: Pearly papules with telangiectasia - Basal cell carcinoma Christmas tree pattern - ptyriasis rosea Nodule with dimple sign - dermatofibroma Pruritic vesicles on extensor surfaces - dermatitis herpeteformis Crateriform nodule - keratoacanthoma Wickham's striae - lichen planus Cafe au lait spots - neurofibroma Honey coloured crust - impetigo Auspitz sign - Psoriasis Papule with central umbilication- molluscum contagiosum Beefy red plaques with satelite lesions - candidiasis Flaccid bullae WITH mucosal involvement - pemphigous vulgaris

Why does sunlight cause rash in SLE? Sunlight (UV Light) - induced apoptosis of keratinocytes -> nuclear antigens more exposed -> antibodies in SLE detects this and attacks area -> inflammation!

@DrMedica_13 Reactive arthritis (Reiter's)

Diagnosis? 🧣✨🧣

@IhabFathiSulima IBD

Only one possible Diagnosis ⁉️

@knowmedge Aspirin desensitization

Happy Saturday! Q1: What is the best next step in a patient with aspirin allergy who will be undergoing elective coronary angioplasty? #ABIM #Cardiology

AHA/ACC/Chest 2026 have introduced a new category for PE (out with the old terms of massive and submassive) -> now: 1) A - asymptomatic (incidental finding) 2) B - Symptomatic (stable) 3) C - Elevated risk (RV strain and high TpN) 4) D - Incipient failure (tachycardia, hypotension) 5) E - Failure (Shock/Arrest)

In thyroiditis, there is no uptake on thyroid nuclear scan.

@Medzonetv Vit A deficiency

What’s this Triad called????

Persistently low C4? Consider hereditary angioedema (HAE).

Cardio-selective beta-blockers in heart failure with reduced ejection fraction - Metoprolol succinate, carvedilol, nebivolol or bisoprolol.

Patient with SLE have photosensitivity due the apoptotic keratocytes, leading to not only issues with dysfunction complement and phagocytic pathway from SLE but also release of dsDNA and other nuclear antigens leading to inflammation.
