Sannu's Story

Unit 8. Case Study 1. Sannu’s Story Sannu has contracted Leprosy. As a sixteen year old teenager, it is hard to pin point when he was infected since Leprosy has a long incubation period. As a small boy traveling barefoot along trails in his village, Sannu’s body has already adapted to his living conditions. Sannu’s feet are tough and calloused. As Sannu ages, so does his Leprosy infection progress. The infection will cause neuropathy in his extremities which will lead to many injuries to his feet and hands. The wounds acquired will be infected for weeks or even months without treatment. The neuropathy caused by the Leprosy infection is characterized by causing a decrease in sensation in the extremities, muscle weakness, and numbness. Sannu’s feet that have been toughened by his environment and life style have been further injured due to lack of sensation and medical treatment. In an attempt to keep his feet clean to aide the healing of his infections, Sannu is more than likely maintaining a sedentary life style. This life style along with the progression of the Leprosy infection will weaken Sannu’s muscles. A feature common to all forms of Leprosy is nerve infection. Nerve damage appears to result from the multiplication of bacilli within Schwann cells and damage to the perineurium. Most of the deformities occurring from Leprosy are in fact due to trauma or a secondary infection. In a Leprosy infection one of the first symptoms are anesthesia to heat and cold. Leprosy affects the peripheral nervous system by attacking the myelin sheath surrounding the axons which affects the reliability and speed of nerve impulses. In other words, the nerve fibers are no longer insulated and nerve impulses cannot be conducted efficiently. There are different types of sensory receptors located throughout the body and are designed based on a selective stimulus response. The appropriate receptive field is stimulated within a sensory receptor producing a response. In Sannu’s
