Vascular lesions are targeted by a variety of wavelength lasers including the KTP (532 nm), pulsed dye (585-595 nm), and the Nd:YAG (1064 nm) laser systems. Pigmented lesions may be treated with a wide variety of lasers due to the broad absorption spectrum of melanin.

Which type of bone tumor is commonly seen in elderly clients quizlet?
Osteosarcoma is the most common type of primary malignant bone tumor in children and young adults. However, primary osteosarcoma in elderly patients is rare. The present study reports 3 cases of advanced osteosarcoma in elderly patients.Jun 7, 2019
What type of laser is alexandrite laser?
An alexandrite laser is one that uses an alexandrite crystal is used as the laser source or medium. The alexandrite laser produces a specific wavelength of light in the infrared spectrum (755 nm). It is considered a red light laser. Alexandrite lasers are also available in the Q-switched mode.
What is Alexander laser?
The Alexandrite Laser emits focused light energy via an alexandrite crystal. As the light passes through the alexandrite crystal, a beam of light 755 nm long is produced. This light selectively targets pigmented areas with light, causing them to break up and fade away.
Which is the first line treatment of Paget's disease?
Bisphosphonates are first-line therapy for Paget's disease, and the advent of the new bisphosphonates permits a dramatic improvement in treatment.
Which medication is used in the treatment of a client with intervertebral disc disease?

Which dermatological problem is treated by using intralesional corticosteroids?
The most common uses of intralesional steroid therapy are in the treatment of excess scar tissue (hypertrophic or keloid scars), acne cysts and alopecia areata (a form of hair loss).
Which type of bone tumor occurs most commonly in elderly client?
Multiple Myeloma, the most common primary bone cancer, is a malignant tumor of bone marrow. It affects approximately 20 people per million people each year. Most cases are seen in patients aged 50 to 70 years old. Any bone can be involved.
Which medication to treat osteoporosis would be contraindicated for a client who has a history of renal calculi?

Ball and socket joints: This type of joint allows side to side, back and forth, and rotational movement. Examples of these joints are the hip or shoulder joints, where the head (ball) of one bone fits into the cavity (socket) of another.
How does Vascular Pigmented Laser work ?
As red skin lesions (those containing predominantly blood vessels) and brown pigmented lesions specifically absorb the laser light, the target lesion can be selectively heated and destroyed without any destruction of the overlying skin or surrounding tissues.
What can Vascular Pigmented Laser treat ?
Pigmented lesions occur in people with all skin types, their appearance, texture and relief variations are usually attributed to:
What is the use of lasers in dermatology?
One of the first applications of lasers in dermatology was the removal of vascular lesions. Laser surgery has become the treatment of choice for many vascular lesions. The most common indications for treatment are vascular anomalies including port-wine stain birthmarks (PWS) and hemangiomas, as well as facial erythema and telangiectasias. Vascular specific lasers have seen an evolution from the historically used continuous wave lasers to pulsed lasers that implement the theory of selective photothermolysis, introduced by Anderson and Parrish in 1983.
Why is epidermal cooling important?
Epidermal cooling was introduced in the 1990s as a means to protect the epidermis, minimizing pigmentary changes and scarring. Cooling also permits the utilization of higher fluences and thus provides greater treatment efficacy. In addition, cooling minimizes discomfort associated with treatment.
What is a PWS?
PWS are vascular malformations that are composed of ectatic capillaries and post-capillary venules in the superficial vascular plexus. PWS vessels are characterized by diminished vascular tone and decreased density of nerves, especially those with autonomic function. In most cases, PWS are congenital, though in rare cases they may be acquired. PWS are found in approximately 0.3% of newborns. They tend to occur on the head and neck, although they may appear anywhere on the body. PWS persist throughout life and many thicken with time ( Fig. 2.2 ). Geronemus et al reported that the mean age of hypertrophy is 37 years and, by the fifth decade, approximately 65% of lesions had become hypertrophied or nodular. There may be associated soft tissue overgrowth, leading to functional impairment in areas such as the lip or eyelid. Vascular blebs often form and may bleed with minimal trauma. These lesions are often considered disfiguring and many patients or their families seek treatment. PWS vessels vary in size from 7–300 µm with older patients tending to have larger vessels.
What Conditions Are Treated with Lasers/Energy-Based devices?
- Lasers being used to treat vascular lesions are capable of treating a variety of birthmarks, dilated vessels such as is seen after chronic sun exposure or in medical conditions such as rosacea, red noses, red cheeks, vascular growths such as hemangiomas, and some scars. Using different wa…
Description of Treatment
- The unique properties of laser light allow specific targets within the skin to be damaged or destroyed leaving surrounding tissues unaffected. The concept of all state-of- the-art lasers and light sources is based on the principle of selective destruction of specific targets within the skin with minimal damage to surrounding structures. Such damage occurs by selecting a wavelengt…
Success Rates/Potential Complications
- Oftentimes treatment approaches are based on the patient’s skin type. With certain conditions or skin types, there is a higher potential for complications. It is very important for the patient to do homework upfront to find a practitioner with the skills and experience to perform the treatment.
What Outcome Should Patients Expect?
- Depending upon the condition, lesions may disappear entirely after 1-2 treatments or require a series of treatments. It is important that the patient follow post-operative care guidelines, such as limiting sun exposure along with regular application of broad-spectrum sunscreen. Updated july 3, 2016
