Common Chronic Conditions

• Chronic Obstructive Pulmonary Disease (COPD - Emphysema, Chronic Bronchitis): Comprehensive management strategies for COPD, focusing on smoking cessation support (critical for slowing progression), appropriate pharmacological therapy (bronchodilators, inhaled corticosteroids), supplemental oxygen therapy assessment (if needed), pulmonary rehabilitation referrals, influenza/pneumococcal vaccinations, and proactive management of exacerbations to improve quality of life, reduce symptoms (breathlessness, chronic cough, sputum production), and slow disease progression.
• Osteoarthritis & Other Chronic Musculoskeletal Pain (e.g., Chronic Back/Neck Pain, Fibromyalgia): Long-term support and care for managing the symptoms of degenerative joint disease and other chronic musculoskeletal pain, focusing on self-management and maintaining an active lifestyle.
• Asthma (All Ages) & Allergic Rhinitis: Comprehensive care for individuals with asthma and related allergies, focusing on patient empowerment, self-management skills, and emergency preparedness for asthma attacks.
• Chronic Kidney Disease (CKD) - Early to Moderate Stages: Early detection, monitoring of kidney function (e.g., eGFR, urine ACR), management of risk factors that can worsen CKD (especially diabetes and hypertension), medication review to avoid nephrotoxic drugs, lifestyle counseling (dietary advice on protein, sodium, potassium), and timely referrals to nephrology for patients with early to moderate stage chronic kidney disease to slow progression and prevent complications.

Dermatological Skin Conditions

• Eczema (Atopic Dermatitis), Contact Dermatitis & Seborrheic Dermatitis: Diagnosing and managing various forms of eczema/dermatitis, including atopic dermatitis (the most common type, often starting in childhood), irritant/allergic contact dermatitis (identifying and avoiding triggers), and seborrheic dermatitis (affecting scalp, face, chest). Management focuses on skincare education (frequent emollients, gentle cleansers, lukewarm baths), trigger identification and avoidance, topical corticosteroids (appropriate potency for site and severity), topical calcineurin inhibitors (TCIs like tacrolimus, pimecrolimus), and antihistamines for itch relief. Referral for patch testing or to dermatology for severe or refractory cases.
• Acne Vulgaris (Mild to Moderate) & Rosacea Management: Personalized treatment plans for acne and rosacea based on severity, skin type, patient preference, and potential impact on self-esteem.
• Primary Care Skin Cancer Screening & Early Detection (Suspicious Mole/Lesion Assessment): Educating patients on sun safety measures (sunscreen, protective clothing, avoiding peak sun hours), the importance of regular skin self-examination using the ABCDEs of melanoma, and encouraging prompt reporting of any changing or new skin lesions.

Joint Muscle Pain

Initiating treatment with low-dose corticosteroids (e.g., prednisone 12.5-25 mg daily) which usually results in a rapid and dramatic improvement in symptoms, thus supporting the diagnosis. Vigilantly screening for and differentiating from Giant Cell Arteritis (GCA/Temporal Arteritis), which can co-exist with PMR (or occur independently) and requires urgent higher-dose steroid therapy and specialist (rheumatology/ophthalmology) referral to prevent irreversible vision loss.
