Photocontact Dermatitis
Phytophotodermatitis, also known as berloque dermatitis or margarita photodermatitis, is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent followed by exposure to ultraviolet light (from the sun, for instance). Symptoms include erythema, edema, blisters (vesicles and/or bullae), and delayed hyperpigmentation. Heat and moisture tend to exacerbate the reaction. A reaction may be elicited in any person who has been exposed to adequate amounts of both a photosensitizer and ultraviolet light. Phytophotodermatitis is not an immunologic response; no prior exposure to the photosensitizing agent is required. The photosensitizing substances found in phototoxic plants belong to a class of chemical compounds called the furanocoumarins, which are activated by long-wavelength ultraviolet (UVA) light. The most toxic of these organic compounds are the linear furanocoumarins, so called since they exhibit a linear chemical structure. Berg ...

Cutaneous
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin ''cutis'' 'skin'). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/os clitoris. All mammals have some hair on their skin, even marine mammals like whales, dolphins, a ...

Child Abuse
Child abuse (also called child endangerment or child maltreatment) is physical, sexual, and/or psychological maltreatment or neglect of a child or children, especially by a parent or a caregiver. Child abuse may include any act or failure to act by a parent or a caregiver that results in actual or potential harm to a child and can occur in a child's home, or in the organizations, schools, or communities the child interacts with. The terms ''child abuse'' and ''child maltreatment'' are often used interchangeably, although some researchers make a distinction between them, treating ''child maltreatment'' as an umbrella term to cover neglect, exploitation, and trafficking. Different jurisdictions have different requirements for mandatory reporting and have developed different definitions of what constitutes child abuse, and therefore have different criteria to remove children from their families or to prosecute a criminal charge. History As late as the 19th century, cruelty to c ...

Heracleum Persicum
''Heracleum persicum'', commonly known as Persian hogweed or by its native name ''Golpar'' ( fa, گلپر) is a species of Heracleum (plant), hogweed, a perennial herbaceous plant in the carrot family Apiaceae. It grows wild in humid mountainous regions in Iran and some adjacent areas. Having been introduced in the 1830s, it has spread across Scandinavia. It is now very common in northern Norway, where one of its names is Tromsø palm. The plant has also been spotted in Sweden. In Finland, it has been declared as invasive species. Persian hogweed is a polycarpic perennial, that is, a mature plant flowers and bears fruit season after season. Invasiveness status In Europe, Persian hogweed is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the whole of the European Union. Uses Food u ...

Heracleum (plant)
''Heracleum'' is a genus of biennial and perennial herbs in the carrot family Apiaceae. They are found throughout the temperate northern hemisphere and in high mountains as far south as Ethiopia. Common names for the genus or its species include hogweed and cow parsnip. The genus name ''Heracleum'' was described by Carl Linnaeus in 1753. It derives from the Ancient Greek () "of Heracles", referring to the mythological hero. Species Many species of the genus ''Heracleum'' are similar in appearance. An outlier is ''H. mantegazzianum'', the large size of which is exceptional. Common species include: * ''Heracleum mantegazzianum'', giant hogweed, native to the western Caucasus region of Eurasia, a serious invasive species in many areas of Europe and North America * ''Heracleum sosnowskyi'', Sosnowsky's hogweed, native to the eastern Caucasus, a common weed throughout Europe and Asia * ''Heracleum persicum'', Persian hogweed, native to Iran, Iraq, and Turkey * ''Heracleum spho ...

Pastinaca
''Pastinaca'' (parsnips) is a genus of flowering plant in the family Apiaceae, comprising 14 species. Economically, the most important member of the genus is ''Pastinaca sativa'', the parsnip. Etymology The etymology of the generic name ''Pastinaca'' is not known with certainty. The name may be derived from the Latin word ''pastino'' (or ''pastinare''), meaning "to prepare the ground for planting of the vine" (or more simply, "to dig") or the Latin word ''pastus'', meaning "food", liberally translated as "Earth-food". Taxonomy For comparison, The Plant List, the Integrated Taxonomic Information System (ITIS), and the National Plant Germplasm System (NPGS) recognize 6, 1, and 16 species in the genus ''Pastinaca'', respectively. In summary, 19 species names are accepted by at least one naming authority. Of those, 13 names are uncontested by some other authority. The following names are accepted by two or more naming authorities: '' Pastinaca hirsuta'' Pančić, '' Pa ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Parsley
Parsley, or garden parsley (''Petroselinum crispum'') is a species of flowering plant in the family Apiaceae that is native to the central and eastern Mediterranean region (Sardinia, Lebanon, Israel, Cyprus, Turkey, southern Italy, Greece, Portugal, Spain, Malta, Morocco, Algeria, and Tunisia), but has been naturalized elsewhere in Europe, and is widely cultivated as a herb, and a vegetable. Parsley is widely used in European, Middle Eastern, and American cuisine. Curly leaf parsley is often used as a garnish. In central Europe, eastern Europe, and southern Europe, as well as in western Asia, many dishes are served with fresh green chopped parsley sprinkled on top. Flat leaf parsley is similar, but it is easier to cultivate, some say it has a stronger flavor. Root parsley is very common in central, eastern, and southern European cuisines, where it is used as a snack or a vegetable in many soups, stews, and casseroles. It is believed to have been originally grown in Sardinia ...

Parsnip
The parsnip (''Pastinaca sativa'') is a root vegetable closely related to carrot and parsley, all belonging to the flowering plant family Apiaceae. It is a biennial plant usually grown as an annual. Its long taproot has cream-colored skin and flesh, and, left in the ground to mature, it becomes sweeter in flavor after winter frosts. In its first growing season, the plant has a rosette of pinnate, mid-green leaves. If unharvested, in its second growing season it produces a flowering stem topped by an umbel of small yellow flowers, later producing pale brown, flat, winged seeds. By this time, the stem has become woody and the tap root inedible. The parsnip is native to Eurasia; it has been used as a vegetable since antiquity and was cultivated by the Romans, although some confusion exists between parsnips and carrots in the literature of the time. It was used as a sweetener before the arrival of cane sugar in Europe. Parsnips are usually cooked, but can also be eaten raw. T ...

Celery
Celery (''Apium graveolens'') is a marshland plant in the family Apiaceae that has been cultivated as a vegetable since antiquity. Celery has a long fibrous stalk tapering into leaves. Depending on location and cultivar, either its stalks, leaves or hypocotyl are eaten and used in cooking. Celery seed powder is used as a spice. Description Celery leaves are pinnate to bipinnate with rhombic leaflets long and broad. The flowers are creamy-white, in diameter, and are produced in dense compound umbels. The seeds are broad ovoid to globose, long and wide. Modern cultivars have been selected for either solid petioles, leaf stalks, or a large hypocotyl. A celery stalk readily separates into "strings" which are bundles of angular collenchyma cells exterior to the vascular bundles. Wild celery, ''Apium graveolens'' var. ''graveolens'', grows to tall. Celery is a biennial plant that occurs around the globe. It produces flowers and seeds only during its second year. The first cul ...

Vitiligo
Vitiligo is a disorder that causes the skin to lose its color. Specific causes are unknown but studies suggest a link to immune system changes. Signs and symptoms The only sign of vitiligo is the presence of pale patchy areas of depigmented skin which tend to occur on the extremities. Some people may experience itching before a new patch occurs. The patches are initially small, but often grow and change shape. When skin lesions occur, they are most prominent on the face, hands and wrists. The loss of skin pigmentation is particularly noticeable around body orifices, such as the mouth, eyes, nostrils, genitalia and Navel, umbilicus. Some lesions have hyperpigmentation, increased skin pigment around the edges. Those affected by vitiligo who are Stigmatization, stigmatized for their condition may experience depression and similar mood disorders.
