Absence of hair from areas where it is normally present.
Loss of scalp and body hair involving microscopically inflammatory patchy areas.
The outer covering of the calvaria. It is composed of several layers: SKIN; subcutaneous connective tissue; the occipitofrontal muscle which includes the tendinous galea aponeurotica; loose connective tissue; and the pericranium (the PERIOSTEUM of the SKULL).
A tube-like invagination of the EPIDERMIS from which the hair shaft develops and into which SEBACEOUS GLANDS open. The hair follicle is lined by a cellular inner and outer root sheath of epidermal origin and is invested with a fibrous sheath derived from the dermis. (Stedman, 26th ed) Follicles of very long hairs extend into the subcutaneous layer of tissue under the SKIN.
A filament-like structure consisting of a shaft which projects to the surface of the SKIN from a root which is softer than the shaft and lodges in the cavity of a HAIR FOLLICLE. It is found on most surfaces of the body.
A potent direct-acting peripheral vasodilator (VASODILATOR AGENTS) that reduces peripheral resistance and produces a fall in BLOOD PRESSURE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p371)
Scalp dermatoses refer to various inflammatory skin conditions affecting the scalp, including seborrheic dermatitis, psoriasis, atopic dermatitis, and tinea capitis, often characterized by symptoms such as redness, scaling, itching, and hair loss.
Inflammation of follicles, primarily hair follicles.
A noninvasive technique that enables direct microscopic examination of the surface and architecture of the SKIN.
Ringworm of the scalp and associated hair mainly caused by species of MICROSPORUM; TRICHOPHYTON; and EPIDERMOPHYTON, which may occasionally involve the eyebrows and eyelashes.
Compulsion to pull out one's hair.
The fibrous tissue that replaces normal tissue during the process of WOUND HEALING.
Abnormal sensitivity to light. This may occur as a manifestation of EYE DISEASES; MIGRAINE; SUBARACHNOID HEMORRHAGE; MENINGITIS; and other disorders. Photophobia may also occur in association with DEPRESSION and other MENTAL DISORDERS.
An inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. It is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. The lesions may be discrete or coalesce to form plaques. Histologically, there is a "saw-tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of T-cells. Etiology is unknown.
Curved rows of HAIR located on the upper edges of the eye sockets.
An insect chemosterilant and an antineoplastic agent.
Presence of less than the normal amount of hair. (Dorland, 27th ed)
The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
Any of several generalized skin disorders characterized by dryness, roughness, and scaliness, due to hypertrophy of the stratum corneum epidermis. Most are genetic, but some are acquired, developing in association with other systemic disease or genetic syndrome.
Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.
Works about studies performed to evaluate the safety of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques in healthy subjects and to determine the safe dosage range (if appropriate). These tests also are used to determine pharmacologic and pharmacokinetic properties (toxicity, metabolism, absorption, elimination, and preferred route of administration). They involve a small number of persons and usually last about 1 year. This concept includes phase I studies conducted both in the U.S. and in other countries.
**I must clarify that there is no recognized or established medical term or definition for 'Texas.' However, if you're asking for a possible humorous play on words using the term 'Texas' in a medical context, here it is:**
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
The systems and processes involved in the establishment, support, management, and operation of registers, e.g., disease registers.
