Nail problems encompass a variety of conditions that can affect the appearance, structure, and function of the nails. Brittle nails, characterized by increased fragility of the nail plate, can result from damage to the nail matrix or changes in nail plate cohesion due to internal or external factors. Simple chronic paronychia involves inflammation of the nail folds, often following cuticle damage. Onycholysis, the detachment of the nail plate from the nail bed, can be caused by dermatologic conditions, infections, drug therapy, or trauma. Other common nail disorders include onychomycosis (fungal infection), nail psoriasis, and onychophagia (habitual nail biting), each presenting…
Athlete’s foot, medically known as tinea pedis, is a common fungal infection of the skin on the feet, primarily caused by dermatophytes, a group of fungi responsible for superficial infections on the skin and nails. This condition is characterized by symptoms such as itching, flaking, and fissuring of the skin, particularly in warm, moist, and airless areas like between the toes. While the infection is prevalent, affecting up to one in four people, it is not limited to athletes and can affect anyone exposed to the fungus, with a higher incidence observed in men. The fungi typically exist in small…
Hives, medically known as urticaria, are raised, red, and often itchy patches of skin that can appear suddenly and disappear without a trace. These patches, also referred to as “wheals,” can vary in size from small dots to large areas covering significant portions of the body. They typically cause itching, stinging, or pain and can last from 24 hours to several days. Hives are caused by irritation in the upper layers of the skin and can sometimes be accompanied by deeper skin inflammation, leading to swelling and pain. Chronic urticaria (CU) is a form of hives that persists for more…
Warts are benign intraepidermal neoplasms caused by infection with the human papillomavirus (HPV), which leads to the overgrowth of skin cells forming small lumps on the skin. These growths are non-cancerous and can vary in size from a few millimeters to several centimeters. Warts are highly contagious and can spread through direct contact with infected skin or surfaces. They are commonly found in children and adolescents, with the most prevalent types being common warts, plantar warts, flat warts, and genital warts. Although warts are typically painless and self-limiting, they can cause physical discomfort and psychosocial distress. The infection can persist…
A boil is an inflamed, pus-filled area of the skin typically caused by a bacterial infection. These infections often originate in hair follicles and are commonly found in moist areas of the body such as the back of the neck, armpits, and groin. Additionally, a specific type of boils known as “smoker’s boils” has been identified in patients with hidradenitis suppurativa (HS), a condition predominantly affecting smokers. The term “smoker’s boils” is proposed to increase awareness and facilitate early diagnosis, potentially preventing the progression of the disease if smoking cessation occurs at an early stage. Types of Boils Boils can…
Dermatitis is broadly defined as an inflammation of the skin, encompassing a variety of conditions such as atopic dermatitis, allergic contact dermatitis, irritant contact dermatitis, and stasis dermatitis.

However, contemporary definitions emphasize a more holistic approach, recognizing eye health as integral to overall physical and mental well-being across all age groups and life stages. This broader perspective includes the prevention and treatment of eye diseases, the promotion of good vision, and the enhancement of quality of life through comprehensive eye care…
Oily skin, also known as seborrhea, is characterized by the overproduction of sebum by oversized sebaceous glands, resulting in a shiny and greasy appearance. This condition is often accompanied by large pores, particularly on the cheeks, nose, chin, and forehead, which can give the skin an “orange peel” texture and make it prone to breakouts, including blackheads and acne. The excessive sebum not only creates a cosmetic concern but also washes away protective and hydrating factors, leading to a paradoxical state where the skin is both oily and malnourished. Factors such as diet, age, gender, ethnicity, and climate can influence…
Wrinkles are defined as “small furrows, ridges, or creases on a normally smooth surface, caused by crumpling, folding, or shrinking”. Scientifically, wrinkling is a form of mechanical instability that can occur in various materials and systems, ranging from human skin to geological formations like lava flows. This phenomenon, also known as buckling, is not merely a cosmetic or structural flaw but can serve functional purposes such as aiding in the assembly of new structures and the characterization of material properties. Hierarchical wrinkling, which involves topographical features spanning multiple length scales, has been observed and utilized in artificial skins, demonstrating the…
Acne is a chronic inflammatory disease of the pilosebaceous units, which include the hair follicle, hair shaft, and sebaceous gland, primarily affecting the face, neck, chest, and back. It is characterized by a variety of lesions, both inflammatory (papules, pustules, nodules) and noninflammatory (comedones, open and closed). The condition is influenced by factors such as increased sebum production, follicular hyperkeratinization, bacterial colonization by Propionibacterium acnes, and an inflammatory response. Acne can be classified into several types based on its clinical presentation, including comedonal, papulopustular, nodular, and cystic forms, with further subdivisions based on lesion characteristics. It is a highly prevalent…
Eczema, also known as atopic dermatitis, is a chronic, relapsing inflammatory skin condition characterized by redness, itching, and oozing, often triggered by exposure to irritants or allergens. The term “eczema” is derived from the Greek word meaning “to boil over,” reflecting the condition’s eruptive nature. It is histologically marked by spongiosis, which is the presence of intercellular edema in the epidermis, giving the skin a spongy appearance. Eczema can be subdivided into atopic and non-atopic types, with atopic eczema being associated with a higher likelihood of developing other allergic conditions such as asthma. Despite its prevalence, there is no universally…
Anxiety is a multifaceted concept that encompasses a range of emotional states, clinical symptoms, and disorders. It is generally understood as a feeling of unease, worry, or fear that arises in response to perceived threats or challenging situations.

Despite its commonality, the term “dry skin” is often misunderstood, with confusion arising between the absence of moisture and the presence…
The liver is a multifaceted organ essential for numerous physiological processes, including macronutrient metabolism, blood volume regulation, immune system support, and endocrine control of growth signaling pathways. It plays a pivotal role in lipid and cholesterol homeostasis, the breakdown of xenobiotic compounds, and the storage and assembly of glucose. The liver is also a central player in the body’s immune defense, enriched with innate immune cells such as macrophages, natural killer cells, and Kupffer cells, which help in the removal of waste molecules and the immunologic elimination of microorganisms. Structurally, the liver consists of parenchymal and non-parenchymal cells, including biliary…
The definition of lower blood pressure has evolved significantly over the years, particularly with the updates in hypertension guidelines. The 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines redefined hypertension by lowering the threshold from 140/90 mmHg to 130/80 mmHg for systolic/diastolic blood pressure. This change was based on epidemiological evidence suggesting that lower blood pressure is associated with reduced cardiovascular risk, although the benefits of antihypertensive therapy at these lower targets are still debated. The concept of “the lower the better” has been challenged due to insufficient evidence from randomized controlled trials supporting significant outcome benefits at these…
