Laser hair removal is one of the medical procedures used to remove unwanted hair from the skin. Laser simply works by distinguishing color differences between the hair and the skin, it goes and hits the darker color area which is the hair, leading to heating of the hair follicle and destroying it making it unable to grow new hair.

This procedure has become more popular over the years, and although laser hair removal is relatively safe in the hands of an experienced technician, side effects may occur. These side effects may range from skin swelling and redness to skin burns and even scaring (replacement of normal skin with fibrous tissue).

Skin burns occur either due to the prolonged use of the laser on specific areas or may result when the intensity of heat is too high. The skin will absorb the laser energy which may lead to skin burns. These burns are usually minor burns but severe burns may also occur ( Second degree burns and third degree burns). Seek medical attention if the burn doesn’t heal or it takes a long time healing.

Other side effects of laser hair removal may include:

Redness, swelling, slight pain, infection, bleeding, color change in the form of darkening of the skin (hyperpigmentation) or lightening of the skin (hypopigmentation).

Before going through a laser hair removal procedure, make sure you discuss all the other options available. You should discuss all the concerns and questions you have with a laser specialist, he/she should be able to answer all your questions, explain all the risks associated with the procedure and tell you if you are an appropriate candidate for the procedure. The success of the procedure depends on how much experience and training the technician/specialist has.

A keloid scar is a type of scar that results in an overgrowth of tissue at the site of healed skin injury due to aggressive healing process. This type of scar grows and extends beyond the site of injury unlike hypertrophic scar. They occur as a result of the body’s continuous production of collagen which is a fibrous protein after the healing of the wound.

They often appear red or pink in color as compared to the surrounding normal skin. They are firm, rubbery lesions; they may appear shiny or as fibrous nodules. Keloid scars may be accompanied by severe itching, pain and may limit mobility if they are extensive. They may vary in size and some types may increase in size. They may occur anywhere on the body although some areas are more susceptible to form keloid scars such as the deltoid region. They occur more often in darker skinned patients.

Treatment:

The treatment of keloid scar varies and the recurrence after treatment is common. Treatment may include:

  1. Steroid injection: this involves injecting steroid into the keloid scar, it may help to reduce the size of the scar and decrease itching and redness that may be associated with these scars. It may be used with other procedures like surgery.
  2. External pressure therapy: eg, compression garments.
  3. Cryotherapy: this involves freezing the keloid scar with a medication.
  4. Surgical therapy: is used if the keloid scar is not responsive to nonsurgical treatment.
  5. Laser surgery: this method involves the use of different lasers depending on the underlying cause of scar. It may be used to smooth the scar, remove abnormal color of a scar, or flatten a scar. This method is often done with other methods like steroid injection.
  • Keloid scars have the tendency to re-occur and multiple treatments may be required.
  • It is important to follow your doctor’s instructions, if you have been prescribed compression garments, it is important to wear them for 23 hours a day (taken off only when bathing), as they can minimize scarring. If you were taught any exercises than you have to do them as they will minimize the scarring.

It is a surgical procedure which involves the placement of a piece of healthy skin in areas where the skin is damaged. It is usually done in an operating room under local or general anesthesia depending on the size of the graft.

Skin grafts can be classified into:

  1. Autografts: where the skin for the graft is taken from the same person.
  2. Allograft: where the skin for the graft is taken from another person.
  3. Xenograft: where the skin for the graft is taken from animals (usually pigs).

A skin graft can be partial thickness where the first two layers of skin are taken, or full thickness skin grafts where the entire thickness of skin is taken which is done in patients with deeper tissue loss.

  • The area where the healthy skin is taken from is called the donor site.
  • The donor site can be any area of the body; it is usually in areas hidden by clothes like the inner thigh.
  • The area which receives the healthy skin is called the recipient site (the graft site).

The donor site will be covered with a dressing for the first one to two weeks. It usually heals within 10-14 days. Lotion is applied to the donor site after the dressing comes off.

For the recipient site (graft site) the dressing is left in place for two to five days before it is changed. The area is very fragile and great care should be taken to ensure that it is protected from trauma and heavy stretching for two to three weeks.

Complications:

  1. Infection.
  2. Bleeding.
  3. Graft failure.
  4. Graft rejection.
  5. Scarring.
  6. Skin discoloration.
  7. Chronic pain.
  8. Change in the sensitivity of skin.

Future care:

It is important to take care of the graft area by protecting it from excessive sun exposure, protect it from dryness (use ointment or creams after consulting with your doctor).

When a person is burned and depending on the severity of burn, the blood vessels including the capillaries may be affected. Combined with the release of chemical substances into the blood, this will lead to increased capillary permeability to fluids, leading to the leaking of fluids from the blood vessels into the tissues. The higher the percentage of burned skin, the more severe the loss of fluid will be and the greater the dehydration will be.

Fluid replacement is one of the important objectives in the initial treatment of burned patients. The amount of fluid needed and the method of fluid given depends on the surface area of the skin burned as well as other factors. There are many formulas used for fluid resuscitation; one of them is called the Parklund Formula in which after the amount of fluids is calculated, it is given through an IV route and the type of fluid is usually Ringer Lactate. Urine output (0.5 ml/kg/hour in adult and 1 ml/kg/hour in children) is one of the methods used to evaluate adequate fluid resuscitation.

  • Fluid is replaced to prevent hypovolemic shock and other associated complications such as kidney failure.
  • Patients with minor burns can be resuscitated with oral rehydration therapy. You have to make sure that your child is taking enough fluids, is not vomiting and that he/she is producing a satisfactory amount of urine.
  • Ringer lactate is usually given because it’s composition is most like normal extracellular fluid.
  • Fluid that leaks from the burned area can accumulate in the burned area only if the burned area was small; if the burned area was large this may lead to accumulation of fluid everywhere in the body.
  • Edema (accumulation of fluid in bodily tissue or body cavity) may become worse after fluid resuscitation and if this edema is in a compartment (closed space of nerves, muscle tissue and blood vessels) covered by dead tissue as a result of the burn which is inelastic and can’t expand, this edema may lead to compression of the blood vessels in the compartment leading to compression of circulation in which escharotomy may be needed to release that pressure. It is advisable to watch the burned areas, especially in the extremities, for signs of decrease blood flow to the affected area (see Escharatomy) after fluid resuscitation.

One of the important components of burn care is nutritional support, nutrition is important for the recovery and healing process of a burned patient. After a burn injury and depending on the severity, the body reacts by increase production of certain hormones which will cause the body to need more nutrition accompanied sometimes with alteration in the carbohydrate, protein and fat breakdown.

There are many ways to assess the nutritional needs of the patient taking into consideration the age, body weight, the percentage of body surface burned, and other factors. The Curreri formula is used for adults and children, Harris-Benedict formula is used for adults and the Galvaston formula used for children. Dietitians and doctors will assess, monitor, and adjust nutrition frequently as patients condition improves or deteriorates.

There are different ways of delivering these nutrients to the patient, depending on the burn and the patient’s condition. The patient may be fed by mouth, through the veins, the intestinal tract through a tube or a combination of more than one method.

Proteins:

Patients with burns need a lot of proteins during healing because of the loss of protein through the burn wound and the muscle breakdown trying to produce extra energy for the healing process.

Carbohydrates:

Carbohydrates make up the bulk of the nutrition and provide the majority of calorie intake. These carbohydrates will be turned by the body into glucose that will be used by the burn wounds as a source of energy. In fact burn wounds can’t use any other source. Carbohydrates will provide the energy for healing allowing protein eaten to be used to rebuilt muscles rather than being used as a source of fuel.

Fat:

Fat is also needed to provide essential amino acids (essential amino acids are amino acids that the body can’t synthesize and has to be supplied) and extra calories, it is recommended that no more than 30% of calories come from fat; too much fat can weaken the immune system.

  • Additional vitamin and mineral supplements may be indicated; among these vitamins are vitamin C, D and E, minerals such as Selenium and Zinc may also be needed. These vitamins and minerals play a role in wound healing, immune response and preventing free radicals from causing damage to the tissues.
  • Burned infants and children represent more complex diet therapy challenges because in addition to the increased nutritional needs imposed by the burn, growth and developmental requirements must be considered. The patient will be assessed and nutritional needs will be calculated as soon as possible after hospital admission.
  • Parents have an important role in the healing process and in encouraging their child to eat, parents after consulting with child’s physician and dietitian can bring the child’s favorite food and have to praise the child even when small amount of food eaten.
  • It is important to follow the instructions given to you at the time of discharge as some patients may be discharged home with special instructions regarding nutritional requirements.

Protection from sunburn:

  1. The sun is most intense between 10am-3pm, so try to limit exposure during these hours.
  2. Wear sunscreens with a sun protective factor (SPF) of at least 30.
  3. Apply sunscreen 30 minutes prior to sun exposure (to allow skin to absorb it); sunscreen absorbs ultraviolet light reducing the amount that reaches the skin.
  4. Wear sunscreens when swimming in an outdoor pool.
  5. Wear hats, protective clothing and sunglasses with UV protection.
  6. Use lip balm with sunscreen to protect lips from burning.
  7. Look for shady areas.
  8. An ounce of prevention is worth a pound of cure.

You should seek medical attention if you experience any of the following:

  1. Feeling dizzy, rapid breathing or rapid pulse, pale or cool skin, extreme thirst, no urine output, sunken eyes.
  2. Fever nausea or rash.
  3. Painful eyes which are sensitive to light.
  4. Blisters which are severe and painful.

Is reddening of the skin occurring after exposure to the sun or other ultraviolet light. It happens when the amount of sun exposure exceeds the ability of the body to protect the skin. The body protects the skin through melanin pigment which acts like an umbrella that covers the skin. Sunburn is a burn which is most commonly a first degree burn part I, II, more severe or deep sunburns can lead to second degree burns with the formation of blisters and rarely third degree burns part I, II. Very light skinned people can have sunburns in less than 15 minutes of exposure to midday sun while dark skinned people may tolerate the same exposure for hours.

Symptoms:

Symptoms of sunburn typically don’t develop until about 2-6 hours after sun exposure, while in children it happens as little as 15-30 minutes after being exposed to the sun without adequate protection.

  1. Pain, red, tender skin, the pain is greatest between 6 and 48 hours after sun exposure.
  2. Blistering can occur hours to days later.
  3. Fever, chills and rash may occur.
  4. Peeling of the skin usually follows several days later.

The symptoms of sunburn are usually temporary while the damage to the skin is often irreversible and may have serious long term effects including skin cancer.

Treatment of sunburns:

  1. Cool baths and showers, or you can place cool wet compresses.
  2. Soothing lotions may be applied if there is no blistering.
  3. If blisters are present don’t break them because that can increase the risk of them getting infected, cover them with a dry bandage.
  4. Pain reducers like Tylenol or Motrin.
  5. If it’s a child, extra fluid might be needed to avoid dehydration.
  6. Oral antihistamine may be needed when the sunburned area begins to peel and become itchy.

Types of malignant melanoma:

  • Superficial spreading melanoma: this type appears as a brown or a black lesion, flat or slightly raised that may show irregular borders and color variegation. It’s the most common type of melanoma in whites and most often appears on the upper arm and back in men and on the legs in women. This type spread initially through the epidermis which is the top layer of the skin, it can spread to the other layers of the skin (dermis and subcutaneous tissue) or even other parts of the body if it’s not diagnosed and treated early.
  • Nodular melanoma: this type of melanoma spreads quickly therefore it’s the most aggressive type; it appears as a rapidly enlarging lump that is usually black in color. It may ulcerate and present as a non healing skin ulcer.
  • Acral lentiginous melanoma: this type usually appears as a black or brown macule that has an irregular border on the palm of the hand, sole of the feet and under the nail. It’s the most common among darker skin color people.
  • Mucosal melanoma: this type may appear on the eyelid, lips, esophagus, penis, vulva, and anus.
  • Lentigo maligna melanoma: this type appears on sun damaged skin of the face, neck and scalp as an irregular shaped, pigmented, flat lesion.

Diagnosis:

Diagnosis is made by examining a new appearing lesion or a change in a previously present lesion, when there is a suspicion, a biopsy will be taken and examined under the microscope to confirm the diagnosis. Other diagnostic test maybe needed to diagnose how far the disease has spread such as US, CT scan, MRI and others.

Treatment:

Treatment is usually done by surgically removing the melanoma with removing normal skin surrounding the lesion. Skin graft maybe needed when the lesion is large. In advanced cases lymph nodes maybe removed if melanoma has spread to lymph nodes. Other modalities of treatment maybe used depending on the stage of the disease which includes Chemotherapy, radiotherapy, and immunotherapy. They may be used in combination depending on the stage of the disease.

Regular follow up is important after treatment to make sure that the tumor hasn’t returned back as malignant melanoma has a risk of recurrence.

Prevention:

  • Wearing protective clothes help to protect the skin from the effect of sunlight and avoid going out during peak hours from 10am-4pm.
  • Using broad spectrum sunscreens with a sun protection factor of at least 15 or more. Wearing sunscreen 30 minutes before sunlight exposure and on all exposed body areas. Reapply frequently.
  • Tanning beds avoidance.
  • Regularly check your skin for any abnormal skin lesion and any change in previously present lesion, notify your doctor of any skin suspicious lesion.
  • Have your doctor examine your skin regularly.

Malignant melanoma is a serious skin cancer affecting the melanocytes. Melanocytes are cells located at the base of the epidermis (see the skin). They are responsible for producing Melanin which is a protein that gives color to the skin, eyes and hair. In the skin melanin pigment acts as an umbrella that absorbs and protects the skin from the effect of ultraviolet radiation. The more melanin produced by melanocyes, the darker the skin.

Malignant melanoma known also as melanoma happens when melanocytes begin to grow in an uncontrollable way. It can happen at all ages but it’s more common in young adults and the risk increases with age. Although anyone can be affected, there are certain risk factors that increase the risk of having malignant melanoma and these risk factors include:

  • Fair colored skin.
  • Excessive sunlight exposure.
  • History of sunburn.
  • Previous history of melanoma or other skin cancer squamous or basal cell carcinoma.
  • Family history of melanoma.
  • Presence of large number of moles (more than 50).
  • Presence of abnormal moles (called a typical or dysplastic mole).
  • People with low immune system such as those with Aids or having organ transplantation.
  • People with Xeroderma pigmentosa witch is a genetic disorder.

Signs and symptoms:

Malignant melanoma can appear in normal looking skin or can be appear in a previously present mole or freckle. Warning Changes in a mole or a freckle include:

The ABCDE guide:

  • A for asymmetry in shape where one half is different from the other half.
  • B for border, change in border may include notched or poorly defined border.
  • C for color, uneven distribution of color or more than one color in a lesion is a warning sign.
  • D for diameter, lesions with a diameter greater than 6 millimeter is a warning sign.
  • E for evolving (changing, enlarging).

Other warning changes may include:

  • Itching.
  • Change in consistency eg, become hard.
  • Change in sensation.
  • Bleeding.
  • Oozing.
  • Pigment spread to the surrounding skin.

Malignant melanoma can appear anywhere in the body where melanocytes are present, some appear on sun exposed areas such as the face and hands while others can appear in places such as under the nail (subungual), between the toes, palms and soles, the eye, genitals and mouth. Primary tumors are more common on the back in men and on the lower extremity in women.

Also called Skin cancer-basal cell, Rodent ulcer
It is the most common type of skin cancer. It originates from the basal cells of the epidermis (see the skin). It occurs more often in men than women and used to be more common after the age of 40 but it is more and more being seen in younger people. Ultraviolet light exposure from sun or other source is the main predisposing factor for developing BCC and that is why the majority occur on sun exposed areas such as face, neck and ear but they can also occur in areas which are not exposed to sunlight.

Certain risk factors increase the risk of basal cell carcinoma which may include:

  • People with chronic exposure to sunlight.
  • People with fair skin.
  • People with red, blond or light brown hair.
  • People with blue or green eyes.
  • People with suppressed or low immunity.
  • People who have been exposed to x-ray or other radiation forms for prolonged time.
  • Arsenic exposure.

clinical features:

There is more than one type of BCC and the appearances vary depending on the type of BCC, it may appear as:

  • A bump or a pearly nodule, it may appear as a light pink, brown or flesh colored.
  • An easy bleeding sore or a sore that doesn’t heal.
  • A well defined red and scaly patch.
  • A scar like lesion.

Diagnosis:

Diagnosis is made by taking a history, examining the lesion and confirming the diagnosis by taking a skin biopsy. There are many types of biopsies and the patient is given local anesthesia before taking the biopsy to numb the skin.

Treatment:

Treatment depends on the type, extent and the location of BCC. Treatment includes:

  • Surgical excision of the tumor after using local anesthesia followed by closing the wound with stitches.
  • Curettage and electrodessication in which the cancer cells are scrapped away with a curette and the remaining is destroyed with an electrical current that generates heat.
  • Mohs surgery in which the surgeon after removing each piece of skin, examines it under a microscope to check if there is any cancer cells left behind, if tumor cells are still present another piece is removed until the skin sample is free from cancer cells. Among other methods, this method provides the highest cure rate.
  • Cryotherapy: this method freezes the tumor cells using liquid nitrogen leading to their destruction.
  • Radiation therapy: this method may be use when cancer has spread to lymph nodes or other organs or for patients who can’t withstand surgery.
  • Topical creams such as imiguimod used for treatment of superficial BCC.

Prevention:

  • Protecting the skin from the effect of sunlight by wearing protective clothes which include hats, clothes with long sleeves and UV protective glasses.
  • Avoid exposure to sunlight in peak hours from 10am-4pm.
  • Sunlight protection by using a broad spectrum sunscreen with a sun protective factor of at least 15 or higher. Apply the sunscreen to all areas of the body 30 minutes before sun exposure. Reapply it frequently.
  • Examining the skin regularly for any lesion that recently appeared, changes in an existing lesion that may be suspicious include: growing, any change in appearance, bleeding, pain, itching, inflammation or a lesion that never heals completely
  • Full skin examination by a qualified physician once a year.
