Pediatric Common Issues

• Childhood Immunization Schedule Management & Counseling: Providing timely and safe immunizations, addressing parental questions or concerns about vaccines with evidence-based information and empathy, managing catch-up schedules if needed, and documenting all immunizations accurately.
• Newborn Care & Infant Feeding Support (Breastfeeding, Formula): Comprehensive medical care for newborns immediately after birth and through the first year of life. Includes routine physical exams, growth monitoring, screening for jaundice and congenital conditions (e.g., hip dysplasia, heart murmurs), umbilical cord care, and vitamin K/eye prophylaxis discussions (hospital-based). Strong focus on infant feeding support, including guidance and troubleshooting for breastfeeding (latch, positioning, supply concerns, mastitis management) and appropriate formula feeding practices, ensuring adequate nutrition and hydration.
• Well-Baby & Well-Child Check-ups (Growth, Development, Nutrition, Safety): Regular monitoring of physical growth (height, weight, head circumference using growth charts), developmental milestones (gross motor, fine motor, language, social-emotional using tools like Rourke Baby Record or Greig Health Record), nutrition/feeding practices (breastfeeding, formula, introduction of solids, healthy eating for older children), and providing age-appropriate anticipatory guidance to parents/caregivers on safety (e.g., car seats, safe sleep, poison prevention, injury prevention), behavior, sleep, dental health, and fostering healthy habits from infancy through school age.

Joint Muscle Pain

• Repetitive Strain Injuries (RSI), Tendinopathies & Work-Related Musculoskeletal Disorders (WRMSDs) - Initial Assessment & Conservative Management: Initial assessment, diagnosis, and conservative management of musculoskeletal pain and dysfunction related to repetitive tasks, sustained awkward postures, or ergonomic factors at work or during hobbies. This includes common conditions like carpal tunnel syndrome (mild-moderate), de Quervain's tenosynovitis, epicondylitis (tennis/golfer's elbow), trigger finger/thumb, rotator cuff tendinopathy, patellar tendinopathy, Achilles tendinopathy, and non-specific arm/neck/shoulder pain attributable to overuse.
• Polymyalgia Rheumatica (PMR) - Diagnosis, Management & Monitoring (Often with Rheumatology Co-Management): Recognizing the characteristic clinical presentation of Polymyalgia Rheumatica (PMR) in older adults (typically age >50 years) – symmetrical morning stiffness and aching in the shoulders, neck, and pelvic girdle – often associated with significantly elevated inflammatory markers (ESR, CRP). 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.

• Occupational Health Screening & Advice (Basic Pre-placement, Return-to-Work): Primary care support for general occupational health questions, routine employment-related medical screenings, and facilitating a safe return to work after illness or injury.
• Infectious Disease Prevention & Outbreak Management Support (Community Level): Promoting individual and community resilience against infectious diseases through education, vaccination, and adherence to public health measures.
• Driver's Medical Examinations (Routine, Age-Related, Commercial): Conducting routine medical examinations as required by provincial transportation authorities for driver's license issuance or renewal, particularly for commercial drivers (truck, bus, taxi) or as mandated by age (e.g., for seniors at specific intervals).

• Helicobacter pylori (H. pylori) Infection - Testing & Eradication Therapy: Testing for Helicobacter pylori infection in appropriate clinical contexts (e.g., patients with peptic ulcer disease, certain types of gastritis, dyspepsia in high-prevalence areas, or family history of gastric cancer) using non-invasive methods like urea breath test, stool antigen test, or serology (less reliable for active infection).
• Venous Insufficiency & Varicose Veins (Conservative Management & Lifestyle Advice): Primary care support for managing discomfort and preventing complications associated with venous disease. Referral to vascular specialists or phlebologists for more advanced treatments (e.g., sclerotherapy, endovenous ablation, surgery) if symptoms are severe, progressive, or complicated by ulceration or recurrent phlebitis.
• Restless Legs Syndrome (RLS) - Initial Assessment & Management: Helping patients manage the uncomfortable sensations and sleep disruption associated with RLS.
• Anemia (Iron Deficiency, Vitamin B12/Folate Deficiency - Diagnosis & Management): Managing common types of nutritional anemia such as iron deficiency anemia (oral or intravenous iron supplementation, dietary advice to increase iron intake and absorption, investigation for source of chronic blood loss if suspected - e.g., GI bleed, heavy menses) and megaloblastic anemia due to vitamin B12 or folate deficiency (oral or parenteral supplementation, dietary counseling, investigation for underlying causes like pernicious anemia, malabsorption syndromes - celiac disease, Crohn's, post-gastric surgery, medication effects - metformin, PPIs).

Common Acute Conditions

• Headaches (Tension-type, Migraine - Acute Symptomatic Relief): Assessment of acute headaches to differentiate types (e.g., tension headache, migraine, cervicogenic), provide initial pain relief strategies (analgesics, NSAIDs, triptans for migraine), identify potential triggers, and rule out serious underlying causes requiring urgent investigation.
