Isibani sokhuni: siyini, senzelwe ini nokuthi sisebenza kanjani
-Delile
Isibani sikaWood, esibizwa nangokuthi ukukhanya kukaWood noma i-LW, iyithuluzi lokuxilonga elisetshenziswa kakhulu ekwelashweni nasekwenzeni ubuhle ukuze kuqinisekiswe ubukhona bezilonda zesikhumba kanye nezici zazo zokunweba ngokusho kwe-fluorescence ebonwe lapho i-lesion ihlaziywa lapho ivezwa ukukhanya okuncane kwe-wavelength UV.
Ukuhlaziywa kwesilonda ekukhanyeni kukaWood kufanele kwenziwe endaweni emnyama engenakho ukukhanya okubonakalayo ukuze ukuxilongwa kuqonde ngangokunokwenzeka futhi, ngakho-ke, udokotela wesikhumba angakhombisa ukhetho olungcono kakhulu lokwelashwa.
Yenzelwe ini
Isibani sokhuni sisetshenziselwa ukuthola izinga nobungako besilonda sedematological, sisiza ukuxilonga nokuchaza ukwelashwa. Ngakho-ke, i-LW ingasetshenziselwa uku:
- Ukuxilongwa okwehlukile kwe Ama-dermatoses athathelanayo, okungabangelwa isikhunta noma amabhaktheriya;
- Izilonda ze-Hypo noma ze-hyperchromic, nge-vitiligo ne-melasma, isibonelo;
- I-Porphyria, okuyisifo esaziwa ngokuqongelelwa kwezinto emzimbeni okuyizandulela ze-porphyrin, ezingatholakala emchameni, ngaphezu kokuhlolwa kwezilonda zesikhumba;
- Ukuba khona kwe-oyela noma ukoma yesikhumba, ne-LW ingasetshenziswa ngaphambi kwezinqubo zobuhle, njengoba ivumela uchwepheshe ukuthi ahlole izici zesikhumba futhi anqume inqubo efanelekile yobuhle yalolo hlobo lwesikhumba.
Ngokombala we-luminescence, kungenzeka ukukhomba nokuhlukanisa izilonda zesikhumba. Endabeni yama-dermatoses athathelanayo, i-fluorescence imelela i-agent ethathelwanayo, kepha esimweni se-porphyria, i-fluorescence yenzeka ngokuya ngezinto ezikhona emchameni.
Endabeni yokuphazamiseka kombala, isibani sokhuni asisebenziswanga nje kuphela ukuhlola umkhawulo nezimpawu zesilonda, kepha futhi nokuhlola ubukhona bezilonda ezingakatholakali ekuhlolweni okujwayelekile kwesikhumba, nge-fluorescence nje.
Yize ukusetshenziswa kwesibani seWood kusebenza kakhulu ekuhloleni nasekuqapheleni ukuvela kwezilonda, ukusetshenziswa kwaso akuhambisani nokuhlolwa okujwayelekile kwesikhumba. Qonda ukuthi ukuhlolwa kwesikhumba kwenziwa kanjani.
Isebenza kanjani
Isibani sikaWood siyithuluzi elincane futhi elingabizi kakhulu elikuvumela ukukhonjwa kwezilonda eziningana zesikhumba ngokusho kwephethini ye-fluorescence ebonwe lapho i-lesion ikhanyiswa kubude obude obuphansi. Ukukhanya kwe-UV kukhishwa kubude obude obungu-340 kuya ku-450 nm yi-arc ye-mercury futhi buhlungwa ngepuleti lengilazi elenziwe nge-barium silicate ne-9% ye-nickel oxide.
Ukuze ukuxilongwa kube okuqonde kakhulu, kuyadingeka ukuthi ukuhlolwa kwesilonda ngesibani seWood kwenziwa i-15 cm kusuka ku-lesion, endaweni emnyama futhi ngaphandle kokukhanya okubonakalayo, ukuze kubonakale kuphela i-fluorescence yesilonda. Iphethini ye-fluorescence yezilonda ezivame kakhulu zesikhumba yilezi:
| Izifo | I-Fluorescence |
| Ama-dermatophytoses | Luhlaza sasibhakabhaka noma luhlaza okwesibhakabhaka ngokukhanyayo, kuya ngezinhlobo ezidala lesi sifo; |
| I-pityriasis versicolor | Okuphuzi okusasiliva |
| I-Erythrasma | Okubomvu-orange |
| Izinduna | Okuluhlaza okotshani noma obomvu |
| I-Vitiligo | Okuluhlaza okwesibhakabhaka okukhanyayo |
| I-Melasma | Nsundu |
| Isifo sokuqina kwemithambo (tuberous sclerosis) | Mhlophe |
| I-Porphyria | Umchamo obomvu osawolintshi |
