The “declining oocyte pool” theory states that a newborn girl is born with millions of eggs, most of which die by atresia. The average age of menopause is 50, however this can vary…

Pneumonia

Overview Pneumonia is infection in the lower respiratory tract and is characterised by fevers, purulent sputum, leucocytosis, low oxygen levels and new lung infiltrates (consolidation) on radiographic imaging. The infection is identified by the site of consolidation. Consolidation is where the lung tissue is filled with fluid (ie. water, blood, pus, microbes). Types of pneumonia…

Achilles Tendinopathy & Rupture

Tendinopathy presents with chronic pain, stiffness, and impaired function, while rupture is an acute injury characterised by a sudden “pop” and loss of plantarflexion power. Achilles tendon injuries are increasingly prevalent due to sports participation, with rupture…

Fibromyalgia

Overview Fibromyalgia is a chronic, nociplastic pain condition characterised by widespread pain with prominent fatigue, sleep disturbance, and cognitive symptoms, reflecting altered central pain processing rather than tissue injury. Global prevalence is ~2–4%, higher in women, ages 20–60, and in those with mood/sleep disorders, obesity, low socioeconomic status, and comorbid rheumatic disease. Major complications include…

Lung Cancer

Overview Lung cancer is the leading cause of cancer deaths in men and women. Lung cancer can be divided into small cell and non-small cell carcinoma. Small cell lung carcinoma presents late stage and has poorer prognosis.  A solitary pulmonary nodule measuring 8 mm or less can be followed radiographically. For larger lesions, a biopsy, whether…

Eosinophilic Granulomatosis with Polyangiitis

Overview EGPA (formerly Churg-Strauss syndrome) is a rare, small-to-medium vessel necrotizing vasculitis characterized by asthma, eosinophilia, and extravascular granulomas. It commonly affects the lungs, skin, peripheral nerves, and heart. Annual incidence: ~1–3 per million; peak onset in 40s–60s; no significant gender bias. Strongly associated with MPO-ANCA positivity in ~40–60% of patients; others are ANCA-negative. Eosinophilia…
