Seabather's Eruption
Seabather's eruption is an itching dermatitis caused by a hypersensitivity reaction to the immature nematocysts of larval-stage thimble jellyfish (''Linuche unguiculata''), sea anemones (''Edwardsiella lineata'') and other larval cnidarians. The cause is sometimes attributed to "sea lice" or "sea ants", but sea lice (Caligidae) are crustacean parasites of fish only. It should not be confused with swimmer's itch. Symptoms and signs Symptoms generally arise later after one takes a shower. It is unusual to notice the eruptions immediately. Symptoms can last from a few days up to two weeks, the shorter time being the norm. The reaction is identified by severe itching around small red papules 1mm to 1.5 cm in size located on areas of skin that were covered by water-permeable clothing or hair during ocean swimming. Initial swimmer exposure to the free-floating larvae produces no effects, as each organism possesses only a single undeveloped nematocyst which is inactive while ...

Diphenhydramine
Diphenhydramine (DPH) is an antihistamine and sedative mainly used to treat allergies, insomnia, and symptoms of the common cold. It is also less commonly used for tremor in parkinsonism, and nausea. It is taken by mouth, injected into a vein, injected into a muscle, or applied to the skin. Maximal effect is typically around two hours after a dose, and effects can last for up to seven hours. Common side effects include sleepiness, poor coordination and an upset stomach. Its use is not recommended in young children or the elderly. There is no clear risk of harm when used during pregnancy; however, use during breastfeeding is not recommended. It is a first generation H1-antihistamine and ethanolamine and works by blocking certain effects of histamine, which produces its antihistamine and sedative effects. Diphenhydramine is also a potent anticholinergic, which means it also works as a deliriant at higher than recommended doses as a result. Its sedative and deliriant effects ...

Linuche Aquila
''Linuche aquila'' is a species of cnidarian found in the tropical and subtropical Pacific Ocean. It is very small and is commonly known as a thimble jellyfish because of its size and shape. The larvae can cause bathers to develop an itchy red rash commonly known as seabather's eruption. Description This is a very small jellyfish with a flat-topped bell separated from the vertical sides by a coronal groove. It can grow to a diameter of and a height of . There are sixteen bluntly oval marginal lappets (flaps) and eight rhopalia (sensory organs) between them. Underneath the bell is a manubrium with a central mouth and four undivided lips. This leads to a four-chambered stomach which opens through four openings into a ring sinus which has sixteen branching pouches extending into the lappets. Eight gonads are present, arranged in four crescent-shaped pairs. This jellyfish has symbiotic zooxanthellae in its tissues which supply a major part of its energy requirements. Ecology Some ...

Linuche Unguiculata
The thimble jellyfish (''Linuche unguiculata'') is a species of cnidarian found in the warm West Atlantic Ocean, including the Caribbean. It is a tiny jellyfish with a straight-sided, flat-topped bell. This jellyfish is the most common cause of seabather's eruption, a reaction caused by the injection of juvenile jellyfish nematocysts into human skin. Description The medusa of the thimble jellyfish has straight sides with sixteen grooves, and a flat top. The coronal groove between the top and sides provides flexibility. The margin of the bell has sixteen lappets (folds), the niches between these bearing alternately rhopalia (sense organs) and short tentacles (eight of each). There is no marginal ring canal. Symbiotic zooxanthellae give the bell an overall orangish-brown colour and the translucent mesoglea has dark flecks. This jellyfish can reach a diameter of and a height of .

Hydrocortisone
Hydrocortisone is the name for the hormone cortisol when supplied as a medication. Uses include conditions such as adrenocortical insufficiency, adrenogenital syndrome, high blood calcium, thyroiditis, rheumatoid arthritis, dermatitis, asthma, and COPD. It is the treatment of choice for adrenocortical insufficiency. It can be given by mouth, topically, or by injection. Stopping treatment after long-term use should be done slowly. Side effects may include mood changes, increased risk of infection, and edema (swelling). With long-term use common side effects include osteoporosis, upset stomach, physical weakness, easy bruising, and candidiasis (yeast infections). While used, it is unclear if it is safe during pregnancy. Hydrocortisone is a glucocorticoid and works as an anti-inflammatory and by immune suppression. Hydrocortisone was patented in 1936 and approved for medical use in 1941. It is on the World Health Organization's List of Essential Medicines. It is available as a ...
