Pediatric Common Issues

• Developmental, Behavioral & Learning Concerns in Children (Screening, Initial Assessment, Guidance & Referral Coordination): Performing routine developmental surveillance and targeted screening (e.g., using Ages & Stages Questionnaires - ASQ) when parents or educators raise concerns regarding potential developmental delays (in speech/language, gross/fine motor skills, cognitive abilities, social-emotional development). Offering initial assessment and guidance for common behavioral issues (e.g., significant tantrums, sleep problems, childhood anxiety, aggression), symptoms suggestive of ADHD, or learning difficulties.
• Common Childhood Infections (Viral & Bacterial - Ear, Throat, Chest, Skin, GI): Expert management of a wide spectrum of acute illnesses affecting infants, toddlers, and school-aged children, including clear guidance for parents on home care, symptom relief, and when to seek urgent re-assessment.
• 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.
• Childhood Immunization Schedule Management & Counseling: Keeping your child's vaccinations fully up-to-date for their individual protection and to contribute to community (herd) immunity, thereby protecting vulnerable individuals.

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.
• Fibromyalgia & Other Widespread Chronic Pain Syndromes - Primary Care Diagnosis & Multimodal Management: Initial assessment and diagnosis of fibromyalgia or other widespread chronic pain syndromes based on established clinical criteria (e.g., ACR criteria for fibromyalgia), after appropriate investigation to rule out other underlying systemic inflammatory or medical conditions. Developing a comprehensive, multimodal management plan focusing on patient education about the condition (central sensitization, pain neurophysiology), promoting self-management, graded exercise therapy (low-impact aerobic, strength, flexibility, aquatic therapy), optimizing sleep hygiene, stress management techniques (mindfulness, relaxation, CBT principles), pain coping strategies, and judicious use of medications targeting central sensitization and associated symptoms (e.g., tricyclic antidepressants like amitriptyline, SNRIs like duloxetine/venlafaxine, gabapentinoids like gabapentin/pregabalin). Avoidance of long-term opioid therapy is generally emphasized.
• Polymyalgia Rheumatica (PMR) - Diagnosis, Management & Monitoring (Often with Rheumatology Co-Management): Long-term management of PMR involves a very slow and gradual tapering of corticosteroids over 1-2 years (or longer), carefully monitoring for clinical relapse (recurrence of symptoms) and adjusting steroid dose accordingly. Also includes monitoring for and managing potential corticosteroid side effects (e.g., osteoporosis - bone protection with calcium/vitamin D, bisphosphonates if needed; hyperglycemia; hypertension; weight gain; mood changes; skin fragility).
• Mechanical Low Back & Neck Pain (Acute, Subacute, Chronic - Uncomplicated): Primary care coordination for back and neck pain, including referral to physiotherapy, chiropractic, massage therapy, or specialist pain services when appropriate for persistent or disabling symptoms.

Common Chronic Conditions

• Asthma (All Ages) & Allergic Rhinitis: Developing and regularly reviewing personalized asthma action plans, educating on proper inhaler technique (metered-dose inhalers, dry powder inhalers, nebulizers), trigger identification and avoidance (allergens, irritants), medication management (relievers, controllers like inhaled corticosteroids, LABAs, LTRAs), and managing asthma exacerbations to improve breathing, prevent flare-ups, and maintain an active lifestyle. Also includes management of associated allergic rhinitis (hay fever).
• Anemia (Iron Deficiency, B12/Folate Deficiency - Chronic): Diagnosing and providing ongoing treatment for common forms of anemia to maintain energy levels and overall health.
• Osteoarthritis & Other Chronic Musculoskeletal Pain (e.g., Chronic Back/Neck Pain, Fibromyalgia): Managing chronic pain and stiffness associated with osteoarthritis in various joints (knees, hips, hands, spine), persistent mechanical low back or neck pain, and conditions like fibromyalgia. This involves a multimodal approach including education, exercise recommendations (strength, flexibility, low-impact aerobics), weight management, pain relief medications (topical, oral NSAIDs, acetaminophen, judicious use of other analgesics like gabapentinoids or TCAs for neuropathic/fibromyalgia components), joint injection considerations, and referrals to physiotherapy, rheumatology or pain clinics if needed.
• Chronic Kidney Disease (CKD) - Early to Moderate Stages: Working collaboratively with patients to manage their kidney health through regular check-ups, proactive interventions, and coordination with specialist renal services when appropriate.

Dermatological Skin Conditions

• Primary Care Skin Cancer Screening & Early Detection (Suspicious Mole/Lesion Assessment): Playing a vital primary care role in the early detection of skin cancer, which significantly improves prognosis, and facilitating prompt access to specialist dermatological care when needed.
• Psoriasis (Mild to Moderate Plaque Psoriasis - Initial Management): Primary care support for individuals with psoriasis, coordinating with specialist care as needed for more advanced treatment options and comprehensive management of this chronic systemic condition.
• Benign Skin Lesion Assessment & Management (Skin Tags, Seborrheic Keratoses, Cysts, Lipomas): Evaluating common benign (non-cancerous) skin growths like skin tags (acrochordons), seborrheic keratoses ('age spots'), cherry angiomas, dermatofibromas, epidermal cysts, and lipomas. Providing reassurance regarding their benign nature and offering in-office removal (e.g., cryotherapy, snip excision, curettage, simple excision for cysts/lipomas if trained/equipped) for cosmetic reasons, if causing irritation, or for diagnostic certainty if there's any ambiguity.

This list offers some examples of common conditions managed in family practice. A diagnosis is always based on an individual assessment by Dr. Samarasinghe. If your specific health concern isn't listed, please contact the clinic to discuss your needs.

• Care for Minor Injuries & Acute Musculoskeletal Complaints: Assessing and treating minor injuries such as sprains, strains, simple fractures (initial assessment and referral for casting/splinting if needed), minor cuts/lacerations (suturing if appropriate), superficial burns, and acute episodes of back or neck pain.

At Dynacare, family medicine is centered on a collaborative partnership to help individuals like you achieve significant improvements in your health, manage ongoing conditions effectively, and enhance your overall well-being. Dr. Samarasinghe frequently works with patients towards goals such as:

• If shortness of breath that comes on suddenly or is worse than their usual asthma/COPD is preventing you from breathing much more easily and deeply, actively participating in more physically strenuous or endurance-based activities, and effectively managing their chronic respiratory conditions (like asthma, COPD, or chronic bronchitis) with greater confidence and fewer limitations, Dr. Samarasinghe can help. The aim is to achieve their children being notably less fearful and more cooperative during doctor visits and even immunizations, specifically because of Dr. Samarasinghe's consistently gentle, patient, and child-friendly communication approach through personalized family medicine care.
• Patients experiencing joint pain in their knees, hips, or hands that's been getting worse and making movement difficult often seek Dr. Samarasinghe's help to improve their quality of life.

• If pain, numbness, or tingling in their hands or wrists that might be carpal tunnel syndrome from computer work is a barrier, Dr. Samarasinghe develops strategies aimed at experiencing a marked and sustained improvement in their overall sense of well-being, daily energy levels, vitality, and a noticeable, positive enhancement in their day-to-day quality of life and functional capacity, facilitating the ability to enjoy effectively and efficiently managing demanding professional work responsibilities, complex household tasks, and personal projects without undue physical fatigue, mental fog, or chronic pain limitations.
• Dr. Samarasinghe's care for difficulty breathing, wheezing, or a flare-up of their asthma or COPD that needs attention is designed to result in their family being effectively connected by Dr. Samarasinghe to invaluable local community resources, patient advocacy organizations, and peer support groups that have demonstrably improved their coping abilities, social support network, and overall well-being, so patients can resume activities such as fully enjoying intimate moments and maintaining healthy, satisfying sexual relationships without the intrusion of physical pain, health-related anxiety, medication side effects, or concerns about performance with confidence.
