KOH test on a vaginal wet mount, showing slings of pseudohyphae of Candida albicans surrounded by round vaginal epithelial cells, conferring a diagnosis of candidal vulvovaginitis. The KOH test , also known as a potassium hydroxide preparation or KOH prep , is a quick, inexpensive fungal test to differentiate dermatophytes and Candida albicans ...
The basis for the diagnosis of kerion is clinical finding, positive microscopic examinations (such as positive KOH preparation, Lactophenol cotton blue wet mount, Chicago sky blue stained (CSB) slide, Calcofluor white stained slide, Periodic acid–Schiff stained slide, and Gomori’s methenamine silver stained slide), mycological culture and modern molecular tests (such as PCR-reverse line ...
In chemical synthesis, the choice between the use of KOH and the use of NaOH is guided by the solubility or keeping quality of the resulting salt. The corrosive properties of potassium hydroxide make it a useful ingredient in agents and preparations that clean and disinfect surfaces and materials that can themselves resist corrosion by KOH.
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
Direct microscopy with 10% KOH would show small to medium conidia with ectothrix hair invasion. [11] Performing a wet mount would show 'racquet shaped hyphae' with few macro and microconidia. [ 11 ] Histological examination of a diseased hair shows clefts that between the inner root sheath and hair.
For topical ulcers it is used together with procaine benzylpenicillin. [10] Typically it is used in skin conditions that produce a lot of liquid. [11] It can be applied as a soaked dressing or a bath. [12] It can be used in children and adults. [13] Petroleum jelly may be used on the nails before soaking to prevent their discoloration. [14]
The alkali denaturation test, also known as A or Apt test, is a medical test used to differentiate fetal or neonatal blood from maternal blood found in a newborn's stool or vomit, or from maternal vaginal blood. [1] [2]
In most countries, fluoroquinolones are approved for use in children only under narrowly defined circumstances, owing in part to the observation of high rates of musculoskeletal adverse events in fluoroquinolone-treated juvenile animals. In the UK, the prescribing indications for fluoroquinolones for children are severely restricted.
