Dr. Catherine Amy Elizabeth O'Blenes

Dr. Catherine O'Blenes diagnoses and treats a wide range of skin, hair, and nail conditions, including:

Nail Disorders (Onychopathies)

• Paronychia (Acute & Chronic): Inflammation or infection of the skin fold around the fingernails or toenails, causing redness, swelling, and pain. Can be acute (bacterial) or chronic (often fungal or irritant-related).
• Lichen Planus of the Nails: Nail involvement in lichen planus, which can cause thinning, ridging, splitting, pterygium formation (scarring from nail fold to bed), or even nail loss.

Hair & Scalp Disorders

• Androgenetic Alopecia (Male/Female Pattern Hair Loss): A common hereditary form of hair loss characterized by a receding hairline and thinning crown in men, and diffuse thinning over the top of the scalp in women.
• Cicatricial Alopecia (Scarring Alopecia - e.g., Lichen Planopilaris, Frontal Fibrosing Alopecia, CCCA): A group of rare disorders that destroy hair follicles, replace them with scar tissue, and cause permanent hair loss. Examples include Lichen Planopilaris, Frontal Fibrosing Alopecia, and Central Centrifugal Cicatricial Alopecia.
• Telogen Effluvium: A type of temporary, diffuse hair shedding often triggered by significant stress, illness, surgery, nutritional deficiencies, or hormonal changes (e.g., postpartum).

Skin Cancers, Precancerous Lesions & Benign Growths

• Basal Cell Carcinoma (BCC): The most common type of skin cancer, typically slow-growing and arising from sun-exposed skin, appearing as a pearly or waxy bump, flat flesh-colored or brown scar-like lesion, or a bleeding/scabbing sore.
• Actinic Keratosis (Solar Keratosis): A rough, scaly patch on sun-exposed skin that is considered precancerous and can sometimes progress to squamous cell carcinoma if left untreated.
• Squamous Cell Carcinoma (SCC): A common form of skin cancer developing in the squamous cells. Often appears as a firm, red nodule or a flat lesion with a scaly, crusted surface on sun-exposed areas. Can grow more rapidly than BCC.

This list is not exhaustive. For personalized advice regarding your specific dermatological condition, please consult with Dr. Catherine O'Blenes.

• Phototherapy (Narrowband UVB, Broadband UVB, PUVA, Excimer Laser): Controlled administration of specific wavelengths of ultraviolet light to treat various skin conditions such as psoriasis, eczema, vitiligo, and cutaneous T-cell lymphoma.
• Dermal Fillers (Hyaluronic Acid, Calcium Hydroxylapatite, PLLA) for Volume Restoration & Contouring: Injectable gels (e.g., Juvederm®, Restylane®, Radiesse®, Sculptra®) used to restore facial volume, smooth out static wrinkles and folds, enhance lip volume, and contour facial features.
• Cryosurgery (Liquid Nitrogen Treatment for Pre-cancers & Benign Lesions): Application of extreme cold (liquid nitrogen) to destroy benign (e.g., warts, seborrheic keratoses) or precancerous skin lesions (e.g., actinic keratoses).
• Hyperhidrosis (Excessive Sweating) Treatment (Topical, Oral, Botulinum Toxin): Management options for excessive sweating of the underarms, palms, or soles, including prescription antiperspirants, oral medications, and botulinum toxin injections.
• Diagnostic Mycology (Fungal Scrapings & Cultures): Collecting skin, hair, or nail samples to identify fungal infections through microscopic examination (e.g., KOH prep) or fungal culture.
• Botulinum Toxin Injections (e.g., Botox®, Dysport®, Xeomin®) for Wrinkles & Hyperhidrosis: Injectable treatments to temporarily relax facial muscles and reduce dynamic wrinkles (e.g., frown lines, crow's feet, forehead lines), or to treat excessive sweating (hyperhidrosis).
• Cosmetic Mole Removal & Skin Tag Removal: Removal of benign moles or skin tags for aesthetic reasons, typically after dermatoscopic confirmation that the lesion is not suspicious for cancer.

Are consultations and dermatological treatments with Dr. O'Blenes, a Dermatologist, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations with a licensed Dermatologist like Dr. O'Blenes, diagnostic procedures (e.g., skin biopsies), and treatments for provincially insured skin conditions (e.g., psoriasis, severe eczema, skin cancer, infections) are generally covered by Ontario Health Insurance Plan (OHIP) in ON when a referral from a family doctor is in place. Purely cosmetic procedures (e.g., Botox for wrinkles, most laser hair removal, fillers for aesthetic enhancement) are typically not covered and are self-pay. It's crucial to discuss coverage specifics for any proposed treatment with Dr. O'Blenes's office or Ontario Health Insurance Plan (OHIP) beforehand, especially if there's a potential cosmetic component.

Do I need a referral to see Dr. O'Blenes, a Dermatologist?

Yes, for medically necessary dermatological care covered by the provincial health plan, a referral from your family physician or another specialist (e.g., an ER doctor for an acute issue) is almost always required to see a Dermatologist such as Dr. O'Blenes. This ensures coordinated care and that your visit is appropriate for specialist assessment. Some dermatologists may offer consultations for uninsured cosmetic services without a referral, but these would be a direct cost to you. Always check with the clinic regarding their specific referral policy.

What kind of sunscreen does Dr. O'Blenes recommend?

While specific brand recommendations can vary, Dr. O'Blenes would likely advise choosing a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF (Sun Protection Factor) of 30 or higher. For daily use, a lighter formulation might be preferred, while for prolonged outdoor activities, water-resistant sunscreen is important. Consider your skin type: individuals with sensitive skin might prefer mineral-based sunscreens containing zinc oxide or titanium dioxide. The most important thing is to apply sunscreen generously and reapply it every two hours, or more often if swimming or sweating. Dr. O'Blenes can provide personalized recommendations based on your skin type and lifestyle during your consultation.

When should someone consider seeing a Dermatologist like Dr. O'Blenes?

A referral to a Dermatologist like Dr. O'Blenes is often recommended by a family physician for: any new or changing moles or skin growths; persistent or severe skin rashes (e.g., eczema, psoriasis) not responding to initial treatments; severe or cystic acne; chronic hives; significant hair loss or scalp disorders; problematic nail conditions (e.g., persistent fungal infections, unusual changes); suspected skin infections; or for expert skin cancer screening, especially if you have risk factors like a personal or family history of skin cancer, numerous moles, or significant sun exposure. Early consultation can be key for effective management and diagnosis.

What does a Dermatologist like Dr. O'Blenes specialize in?

A Dermatologist, such as Dr. O'Blenes, is a medical doctor with highly specialized training in diagnosing and treating over 3,000 conditions affecting the skin, hair, and nails in patients of all ages – from newborns to seniors. This includes a wide spectrum of diseases from common issues like acne, eczema, and psoriasis, to more complex conditions like skin cancer, autoimmune skin disorders (e.g., lupus, pemphigus), severe allergic reactions, and genetic skin diseases. She is a Dermatologist specializing in the comprehensive medical and surgical care of skin, hair, and nail conditions. Dr. O'Blenes offers various medical, surgical, and potentially cosmetic treatments depending on their practice focus.

If Dr. O'Blenes recommends phototherapy, what does that involve?

Phototherapy, also known as light therapy, is a medical treatment where your skin is exposed to specific wavelengths of ultraviolet (UV) light under strict medical supervision. Dr. O'Blenes might recommend it for conditions like psoriasis, eczema, vitiligo, or cutaneous T-cell lymphoma. Treatments are typically given 2-3 times a week in a specialized light cabinet or with a handheld device for smaller areas. The type of UV light (e.g., Narrowband UVB, PUVA) and treatment duration are carefully controlled. It works by reducing inflammation and slowing down the rapid growth of skin cells. You'll be given specific instructions, including eye protection.
