Sannu's Case Study Answers
Sannu’s Story
A. In Sannu’s case why is there both sensory loss and muscle weakness?
Leprosy is a disease that has been known since biblical times. It causes skin sores, nerve damage, and muscle weakness that gets worse over time. Leprosy is caused by the bacterium Mycobacterium leprae. It is not very contagious and it has a long incubation period (time before symptoms appear), which makes it hard to know where or when someone caught the disease. Children are more likely than adults to get the disease. Leprosy has two common forms: tuberculoid and lepromatous. Both forms produce sores on the skin. However, the lepromatous form is most severe. It causes large lumps and bumps (nodules).Leprosy is common in many countries worldwide, and in temperate, tropical, and subtropical climates. About 100 cases per year are diagnosed in the United States. Most cases are in the South, California, Hawaii, and U.S. islands.
Due to the constant lifestyle of unclean conditions of the water, environment and not wearing shoes placed him in the high risk category, and kept him susceptible to infection and unable to keep himself free from further exsposure/injury.

Skin nociceptors may be divided into four categories based on function. The first type is termed high threshold mechanonociceptors or specific nociceptors. These nociceptors respond only to intense mechanical stimulation such as pinching, cutting or stretching. The second type is the thermal nociceptors, which respond to the above stimuli as well as to thermal stimuli. The third type is chemical nociceptors, which respond only to chemical substances (Figure 6.2). A fourth type is known as polymodal nociceptors, which respond to high intensity stimuli such as mechanical, thermal and to chemical substances like the previous three types. A characteristic feature of nociceptors is their tendency to be sensitized by prolonged stimulation, making them respond to other sensations as
