Cryotherapy is a technique that uses an extremely cold liquid or instrument to freeze and destroy abnormal skin cells that require removal. It is a freezing substance or mixture used to produce very low temperatures. The technique has been in use since the turn of the century, but modern techniques have made it widely available to dermatologists, Neurologists, Orthopedists, and primary care doctors. The technique is also known as cryocautery or cryosurgery.
Cryotherapy is used to destroy a variety of benign skin growths, such as warts, pre-cancerous lesions (actinic keratoses), and malignant lesions (basal cell and squamous cell cancers). It has been used at several medical centers for tumors of the prostate, liver, lung, breast, and brain as well as for cataracts, gynecological problems, and other diseases. The goal of cryotherapy is to freeze and destroy targeted skin growths while preserving the surrounding skin from injury.
Dr. Valerie Njee quotes several occasions where she has found Cryotherapy to be very beneficiary and cost effective to both Patients, Government Agencies and HMOs; by narrowing the risk factors of the patients and at the same time, maintaining their normal visitation to their primary care givers.
In this situation, Dr. Jason Fotso describes how to deal with Fractions and Bruises. The best and proficient method / technique, usually reserved for fractions and bruises, the physician dips a cotton swab or other applicator into a cup containing a “cryogen” and applies it directly to the bruise to freeze it which helps to norm the pains, stop bleeding and protects the expose skin blood vessels of his patients. After clean gloss is applied in the case of a bruise, or in the case of a fraction, bandage is loosely wrapped on the fractions, then a cold ice pack can then be placed on the injured position. In other situations, a pad covered with cryogen which is consist of liquid Nitrogen is laid on the area of injury. At a temperature of –320°F (–196°C), liquid nitrogen is the coldest cryogen available. The goal is to freeze the fraction or bruises as quickly as possible, and then let it thaw slowly to cause minimum destruction of the skin / bone cells. A second application may be necessary depending on the size of the injury. In another approach, a device is used to direct a small spray of liquid nitrogen or other cryogen directly onto the fraction or bruise. Freezing may last from five to 20 seconds, depending on the size of the injury. A second freeze-thaw cycle may be required. Sometimes, the physician inserts a small needle connected to a thermometer into the fraction to make certain the fraction is cooled to a temperature low enough to guarantee minimum destruction. In a third option, liquid nitrogen or another cryogen is circulated through a probe to cool it to low temperatures. The probe is then brought into direct contact with the fraction or bruise to freeze it. The freeze time can take two to three times longer than with the spray technique.
In the case of cervical cancer, depending on stage of the cancer, if it is benign or malignant neoplasm. Sample tissues are clipped from the infected area to perform further tests such as hematocrit and intense microscopic examination of the tissue using hand held microscope to aid for best visual results.
Comparison to normal tissues and hematoma (a solid swelling of clotted blood within the tissues) is needed to determine if the cancer is benign or malignant. If the cancer is malignant, they invade and destroy the surrounding tissue which may form metastases and untreated or unresponsive to treatment, and may prove fatal. In such case, the primary care physician would have to refer their patients to specialized cancer clinic covered by their healthcare insurance.
In situations where a tumor is determined to be benign, cryotherapy is usually the best treatment to offer to the patient by applying cold pads to the infected location 2 to 3 times daily and prescribe medication to reduce inflammation internally. During this period, nutritive meals and oriental medicine are recommended to eradicate such tumors. In other situations, cryotherapy is usually performed as follows: for external tumors, liquid nitrogen is applied directly to the cancer cells with a cotton swab or spraying device; for internal tumors, liquid nitrogen is circulated through an instrument called a cryoprobe that is placed in contact with the tumor. To guide the cryoprobe and to monitor the freezing of the cells, the treating physician uses ultrasound to guide his work and spare nearby healthy tissue.
The eye is one of our sensory organ. The nerves of the eyes are very thin and need dedication when dealing with irritation or infection of the eye. Neuroscience studies and Ophthalmology enables detailed understanding of what is necessary to apprehend during incidence which may cause such irritation to the eye. In the case of Reddish Eye(s) it is usually non-specific term and may occur due to a series of disturbances or disruptions. It may occur in one or both eyes. Red eye could be due to an illness, injury, fatigue, eye infections, or other condition such as allergies.
Doctors tend to take immediate action when a patient comes in with red eyes. It is a very common condition that is usually caused by the following such as fatigue, substance abuse, allergies, or cold/flu. Red eyes are also referred to as bloodshot eyes, pink eye, and allergy eyes.

Complaints/What brought the patient into the Doctor office: Patient complaint of left eye irritation. Complaint of aches and pains.
In the case of Reddish Eye(s) it is usually non-specific term and may occur due to a series of disturbances or disruptions. It may occur in one or both eyes. Red eye could be due to an illness, injury, fatigue, eye infections, or other condition such as allergies.
Medical Recommendations: I recommend to avoid rubbing eye, wash eye with cold water and do not sleep on the side with affected eye. You may take acetaminophen products such as Tylenol, Fancida or Ibuprofen to relieve pains.
If coloration continues after 3 to 5 days call to see the doctor.

In dermatology applications, there are three main techniques used in cryotherapy. In the simplest technique, usually reserved for warts and other benign skin growths, the physician dips a cotton swab or other applicator into a cup containing a “cryogen” such as liquid nitrogen and applies it directly to the skin growth to freeze it. At a temperature of –320°F (–196°C), liquid nitrogen is the coldest cryogen available. The goal is to freeze the skin growth as quickly as possible, and then let it thaw slowly to cause maximum construction of the skin cells. A second application may be necessary depending on the size of the growth. In another approach, a device is used to direct a small spray of liquid nitrogen or other cryogen directly onto the skin growth. Freezing may last from five to 20 seconds, depending on the size of the lesion. A second freeze-thaw cycle may be required. Sometimes, the physician inserts a small needle connected to a thermometer into the lesion to make certain the lesion is cooled to a temperature low enough to guarantee maximum construction. In a third option, liquid nitrogen or another cryogen is circulated through a probe to cool it to low temperatures. The probe is then brought into direct contact with the skin lesion to freeze it. The freeze time can take two to three times longer than with the spray technique.
When used for cancer treatment, cryotherapy is usually performed as follows: for external tumors, liquid nitrogen is applied directly to the cancer cells with a cotton swab or spraying device; for internal tumors, liquid nitrogen is circulated through an instrument called a cryoprobe that is placed in contact with the tumor. To guide the cryoprobe and to monitor the freezing of the cells, the treating physician uses ultrasound to guide his work and spare nearby healthy tissue.
No extensive preparation is required prior to cryotherapy. The area to be treated should be clean and dry, but sterile preparation is not necessary. Patients should know that they will experience some pain at the time of the freezing, but local anesthesia is usually not required. In dermatology applications, the physician may want to reduce the size of certain growths such as warts prior to the cryotherapy procedure, and may have patients apply salicylic acid preparations to the growth over several weeks. Sometimes, the physician will pare away some of the tissue using a device called a curette or a scalpel. In the case of cervical cryotherapy, the procedure is not performed during, or from two to three days before, the menstrual period.
In dermatology applications, redness, swelling, and the formation of a blister at the site of cryotherapy are all expected results of the treatment. A gauze dressing is applied, and patients should wash the site three or four times daily while fluid continues to ooze from the wound, usually for five to 14 days. A dry crust will form that falls off by itself. Wounds on the head and neck may take four to six weeks to heal, but those on the body, arms, and legs can take longer. Some patients experience pain at the site following the treatment. This can usually be eased with acetaminophen (Tylenol), though in some cases a stronger pain reliever may be required.
In dermatology applications, cryotherapy poses little risk and can be well tolerated by elderly and other patients who are not good candidates for other surgical procedures. As with other surgical procedures, there is some risk of scarring, infection, and damage to underlying skin and tissue. These risks are generally minimal in the hands of experienced physicians.
Care should be taken, however, in subjecting people with diabetes or certain circulation problems to cryotherapy for growths located on their lower legs, ankles, and feet. In these patients, healing can be poor and the risk of infection can be higher than for other patients.
Although cryotherapy is a relatively low-risk procedure, some side effects may occur as a result of the treatment. They include:
In cancer treatment, cryosurgery does have side effects, although they may be less severe than those associated with conventional surgery or radiation therapy. Cryosurgery of the liver may cause damage to the bile ducts or major blood vessels, which can lead to heavy bleeding or infection. Cryosurgery for prostate cancer may affect the urinary system. It also may cause incontinence (lack of control over urine flow) and impotence (loss of sexual function), although these side effects are often temporary. Cryosurgery for cervical tumors has not been shown to affect fertility, but this possibility is under study. More studies must be conducted to determine the long-term effects of cryosurgery as a cancer treatment approach.
Some redness, swelling, blistering, and oozing of fluid are all common results of cryotherapy. Healing time can vary by the site treated and the cryotherapy technique used. When cryogen is applied directly to the growth, healing may occur in three weeks. Growths treated on the head and neck with the spray technique may take four to six weeks to heal, while growths treated on other areas of the body may take considerably longer. Cryotherapy boasts high success rates in permanently removing skin growths; even for malignant lesions such as squamous cell and basal cell cancers, studies have shown a cure rate of up to 98%. For certain types of growths such as some forms of warts, repeat treatments over several weeks are necessary to prevent the growth’s return.
Alternatives to cryotherapy depend on the specific medical condition being treated. A general alternative is the use of conventional surgical procedures.

Cryotherapy is performed by the treating physician, who may be a gynecologist(cervical cryotherapy) or a dermatologist (wart removal) or an oncologist (tumor removal). The procedure is usually carried out on an outpatient basis, but may require a hospital setting depending on the condition requiring the cryotherapy.
