Narrow-band UVB Phototherapy

What is phototherapy?

Phototherapy is the use of light to treat diseases.

What is narrow-band UVB phototherapy?

Narrowband UVB phototherapy is the use of a specific wavelength (311 nm to 312 nm), in contrast to broad band UVB (290 nm to 320 nm), to treat certain skin diseases. Narrow band UVB has been shown to be more effective than broad band UVB in the outcome of the treatment with shorter and less exposure times.

What is narrow-band UVB used for?

Narrow band UVB is used to treat skin conditions like psoriasis, vitiligo, atopic eczema, pruritus, polymorphous light eruption, cutaneous cell lymphoma and lichen planus.

What are the side-effects of narrow-band UVB treatment?

Side effects are not frequent and tend not to be severe. There is a possibility of getting a burn, like a sunburn and the skin condition may sometimes get worse in the initial part of the treatment. Long term exposure can cause skin ageing and increase the risk of skin cancer just like prolonged exposure to sunlight.

What does the treatment involve?

The treatment involves standing in a specially designed light cabinet with tubes emitting UVB light. The patient is undressed and stands in the centre of the light box with his eyes and face protected. Light is emitted and the treatment last for a short time from seconds to minutes. Treatment is usually given at least three times a week at the beginning and for maintenance, the treatment frequency is reduced to once or twice a week. The amount of UVB delivered depends on the condition, the skin type of the patient, and other factors.

The patient expects to see light redness or tanning of the skin after the treatment. Improvement in the skin condition is expected within 10 treatments.

Mole Check (Surveillance)

What are moles?

Moles, also called naevi (singular: naevus) or melanocytic nevi, are common, benign skin lumps due to aggregation of pigment cells (melanocytes). Melanocytes produce the pigment melanin, which gives our skin its colour and protects it from ultraviolet radiation. When melanocytes cluster together, they form naevi or moles. The presence of melanin explains why moles are usually brown to black in colour, though some may be flesh-toned or pink. Moles can be flat or raised, and range in size from few millimeters to many centimeters.

When and how do moles develop?

Congenital melanocytic naevi are moles that are present at birth or develop in the first 2 years of life.

Acquired melanocytic naevi are moles that develop after the age of 2 years. Most people will acquire more moles as they grow up, until the age of 30 – 40. Thereafter, the number of moles tend to decrease. A new mole that appears in adulthood needs to be monitored and checked if growing or changing.

A tendency to develop multiple moles runs in some families. Sunburn or excessive sun exposure can contribute to new mole formation. Hence people with fairer skin are at higher risk to getting new moles.

How do I know if something is a mole?

Most moles can be easily recognized by their appearance. Your dermatologist may use a specialized tool called a dermatoscope (or dermoscope) to examine a mole in more detail. A dermatoscope is a handheld instrument that magnifies a mole up to 20 times and allows the doctor to examine the mole’s pigment pattern in greater detail. Most dermatologists have basic training in dermatoscopy. At Tham Siew Nee Skin Clinic, Dr Koh Hong Yi has undergone further training and certification and holds a Professional Certificate in Dermoscopy.

What is the risk of melanoma skin cancer developing in a mole?

There is a small risk of melanoma arising from a previously benign mole. There is a strong link between developing melanoma and having recurrent or excessive sun exposure, and having many moles.

What do we do during a mole check?

Your doctor will examine your skin including your moles, focusing on any that you may be worried about. Suspicious moles may either be recorded for further close monitoring, or recommended for removal.
