Leprosy or Hansen's disease is a chronic infection that affects the mucous membrane, skin, and nerves. It causes discoloration, lumps, disfigurement, and deformities in the skin. Leprosy is spread when a healthy person comes in regular and close contact with the droplets of leprosy patients. The disease is most prevalent through respiratory route transmission and insects.
Types of Leprosy Intermediate Leprosy
Intermediate leprosy is the earliest stage of leprosy, patients suffer from flat lesions which may heal by themselves.
Tuberculoid leprosy is a mild and less serious type of leprosy. People suffering from this disease have no sensation in the affected area, and some patches of flat and pale-colored skin. This infection heals on its own or may persist and progress to a more severe form.
Borderline tuberculoid Leprosy
Borderline tuberculoid Leprosy has symptoms similar to the tuberculoid but the infections may be smaller and more in number which may continue and revert to tuberculoid, or any other advanced form.
The sign and symptoms of mid-borderline are similar to borderline tuberculoid leprosy. The symptoms include reddish plaques with numbness which may regress or progress to another form.
Borderline leprosy is a cutaneous skin condition, characterized by multiple wounds or scars, plaques, and flat raised bumps that may continue or regress.
Lepromatous Leprosy is a more severe type of disease with many lesions with bacteria. The affected region has numbness, and muscle weakness, full of bumps and rashes. Other symptoms include hair loss, limb weakness, and other body parts like the male reproductive system, kidneys, and nose are also affected.
What Are The Causes Of Leprosy Or Hansen's Disease?
Leprosy is caused by the bacteria Mycobacterium Leprae, the causes of leprosy can be:
Runs in families. Individuals with weakened immune systems. People living in high-risk areas. Close contact with the infected person. Malnutrition, etc.
What Are The Symptoms Of Leprosy Or Hansen's Disease?
It takes almost 3-5 years for the symptoms to appear after coming in contact with the bacteria, in some cases, symptoms appear after 20 years after being infected. The time between being exposed to the appearance of symptoms is known as the incubation period. Leprosy causes scarring skin sores and nerve damage in the limbs affecting the peripheral nerves, skin, upper respiratory tract, and eyes. Mentioned below are some of the symptoms of Leprosy:
Severe pain. Growth on skin. Stiff, dry, and thick skin. Paralysis or muscle weakness. Numbness in hands, arms, feet, and legs. Bleeding nose. Enlarged nerves. Ulcers on the soles of the feet. Non-sensitive lesions on the body. Eye problems might even cause blindness.
Leprosy is caused by Mycobacterium leprae. Once the bacteria penetrate and multiply within the host cells, the immune system creates a response toward the infected cells, which results in symptoms. The pathology depends on the immune response towards the host and varies with the type of leprosy.
Diagnosis Of Leprosy Or Hansen's Disease.
A physical examination is done to look for the signs and symptoms of leprosy.
A biopsy is done by removing a small piece of skin or nerve and sent to the laboratory for testing.
A skin test or a skin lesion biopsy is advised to determine the form of leprosy. A small amount of Hansen's disease-causing bacterium, which has been inactivated, is injected into the skin, typically on the upper forearm. Patients who have tuberculoid or borderline tuberculoid Hansen's disease will experience a positive result at the injection site.
Treatment For Leprosy Or Hansen's Disease.
Medication: Dapsone, Ofloxacin. Clofazimine, etc.
Note: Medication should not be taken without the doctor's prescription.
Surgery is indicated when the symptoms are not controlled by medication.
What Is The Physiotherapy Treatment For Leprosy Or Hansen's Disease?
Heat therapy enhances joint movement. The affected part is soaked in warm water, which also increases blood circulation.
It can be used in the walking cast to prevent pressure on the calf area and for transmitting weight on the foot. Bohler iron enhances the healing process in case of ulcers.
The boot is a cast used to heal plantar ulcers on the forefoot. The cast is applied below the malleoli, covers the entire foot, just like a boot.
Assistive devices can be recommended to protect the affected area from pressure injuries.
Cleaning the skin by soaking the part in soap water, rubbing off thick skin, oiling, self-massage, and protecting the part from infection.
Splints are used to immobilize the affected part. Static splints immobilize and prevent movement in the area, dynamic splints allow movements that help in maintaining function.
The affected part is elevated to decrease inflammation by draining it.
Motor training is recommended for leprosy patients suffering from motor impairments such as grasp, pinch, and prehension to enable and enhance performance in ADL and work-related activities.
Range of motion Exercises:
Range of motion exercises can help maintain muscle bulk and tone. The physiotherapist suggests passive exercises followed by active assisted and then active exercises.
Strengthening exercises include resistive exercises which help increase muscle strength.
Leprosy is curable and treatment in the early stages can prevent disability, if left untreated, it can cause progressive and permanent damage to the skin, limbs, nerves, and eyes.
