Concept and Etiology
Paget’s disease refers to a chronic disease of the skeleton. In healthy bone, a remodelling process
takes place that involves the removal of old pieces of bones and replacing them with fresh and new
bones (Paget's disease of bone - symptoms and treatment - Ortho info - AAOS. Ortho Info, 2021).
When a person suffers from Paget’s disease, the normal remodelling process shifts out of balance,
and it results in new bones that are abnormal in shape, brittle and weak. This medical condition
weakens the musculoskeletal system. The medical condition also has an impact on the
integumentary system that involves a set of organs that form the outermost layer of the body. c Both
the integumentary system and musculoskeletal system function together and are responsible for
providing structure to the body and maintaining a protective barrier against external elements
(Integumentary system. Inner body, 2021). It deviates from the definition of health as it adversely
affects the quality of life of the affected individuals.
Classification
The disease can be classified into mammary and extramammary. The mammary classification type is
rare, and it is generally linked with intraductal cancer. Approximately 93 to 100 % of cases belong to
this category (Lopes et al., 2015). The extramammary type is regarded to be an adenocarcinoma
that originates from the sin region or the skin appendages in the regions with apocrine glands
(McDaniel et al., 2018).
Clinical Manifestations
Some of the common signs of Paget’s disease include flaky or scaly skin, redness, itching, a lump in
the breast, and thickening of the skin on the breast area (McDaniel et al., 2018). Some of the main
symptoms of the health condition include fatigue, weakness, loss of appetite, pain in the abdominal
and constipation. The symptoms relating to the condition could also arise from the effect of the
ailment on the level of calcium in the blood stream. Typically, the signs and symptoms relating to
the health condition occur on one breast only.
Diagnostic Tests
In many cases, Paget’s disease is discovered when x-rays are taken for other health-related reasons
or when the routine blood work reveals an elevated blood serum alkaline phosphate level (Paget's
disease of bone - symptoms and treatment - Ortho info - AAOS. Ortho Info, 2021). Thus, the
diagnosis of the medical condition is incidental generally. Apart from x-rays, laboratory tests can
also be performed to aid in the conformation of the diagnosis. Bone scanning is also used as a
useful diagnostic test that helps to determine the bone that has been affected by the condition. On
some occasions, a biopsy is helpful to confirm the diagnosis of Paget’s disease (Paget's disease of
bone - symptoms and treatment - Ortho info - AAOS. Ortho Info, 2021).
Concept & Etiology:
Vitiligo is a rare condition characterized by small patchy areas of hypopigmentation (Story 2017).
This condition affects the integumentary system because it involves the cells that produce melanin.
These cells die or no longer form melanin and cause white patches to form irregular shapes on the
skin. The condition of vitiligo itself does not deviate from the definition of health but the potential
causes of it can. Potential causes such as hypothyroidism and Addison's disease do deviate from the
definition of health.
Classification: c Vitiligo can be classified into five categories:
Generalized-affects many parts of the body symmetrically
Segmental-restricted to one side or area of the body
Universal-affects nearly all surfaces of the body
Localized or focal-affects only one or a few areas of the body
Acrofacial-affects the face and hands and around body openings such as eyes, nose, or ears
Signs and Symptoms: Signs of vitiligo are patchy loss of skin colour which may first appear on the
hands and the face, premature whitening of the hair on the head. Also, hair on the eyelashes,
beard, and eyebrows. There may also be signs of loss of colour to the tissue that line the mucous
membrane (mouth).
Diagnostic Test: c Diagnostic test to determine a diagnosis of vitiligo are a history and physical
examination which may include a Woods's light exam. A skin biopsy, serum autoantibody, hormone
and B12 level measurements are also diagnostic test that can be performed.
Concept and Etiology: Fractures are known as traumatic musculoskeletal disorders and are the most
common type, which happens because of a break in the rigid structure of the bone (Story, 2018). c
Fractures can occur when a patient has a fall, is involved in an accident, or has a sports-related
injury (Story, 2018).
Classification:
Simple fracture—a fracture with a single break in the bone and in which bone ends maintain their
alignment and position:
Transverse fracture—a fracture straight across the bone shaft
Oblique fracture—a fracture at an angle to the bone shaft
Spiral fracture—a fracture that twists around the bone shaft
Comminated fracture—a fracture characterized by multiple fracture lines and bone pieces
Greenstick fracture—an incomplete fracture in which the bone is bent and only the outer curve of
the bend is broken; commonly occurs in children because of minimal calcification and often heals
quickly
Compression fracture—a fracture in which the bone is crushed or collapses into small pieces
(Story, 2018)
Clinical Manifestations:
Deformity (e.g., angulation, shortening, and rotation)
Swelling at the site (due to the inflammatory process triggered by the tissue trauma)
Inability to move the affected limb
Crepitus (grating sound or sensation, usually occurring with movement)
Pain (results from tissue trauma and muscle spasms triggered by the bone fragments)
Paraesthesia
Muscle flaccidity progressing to spasms
(Story, 2018)
Diagnostic Tests:
Assess the patient’s history, physical examination (including neurovascular assessment), and X-rays.
(Story, 2018)
Fibromyalgia
Concept and Etiology: How does the disease affect the musculoskeletal and integumentary systems
in particular? How does it deviate from the definition of health discussed in Module One?
Fibromyalgia is neurological disease that affects the muscle and skin. It attributes to pain to touch,
pressure to muscles, and occasionally can affect joints. While it most commonly affects women, it
can also affect men. It generally begins in middle adulthood but can also affect teens or old age.
Populations at higher risk for fibromyalgia are those with a rheumatic disease such as osteoarthritis,
lupus, rheumatoid arthritis, or ankylosing spondylitis (Amigues M.D., 2019).
Classification: How is the disease classified?
Fibromyalgia was historically classified as an inflammatory musculoskeletal disease and now is
classified as disease of the central nervous system. (Understanding Fibromyalgia and Its Related
Disorders, 2008)
Clinical Manifestations (Symptoms and Signs): What are the symptoms and signs of the disease or
disorder? Be sure you understand the difference between symptoms (subjective) and signs
(objective).
Signs and symptoms according to The American College of Rheumatology include (Amigues M.D.,
2019):
Tenderness to touch, pressure affecting muscles, and occasionally joints or even the skin
Extreme fatigue
Sleep problems
Problems with memory or brain fog
Depression
Anxiety
Migraine/ tension headaches
Irritable bowel syndrome (commonly called IBS)
Gastroesophageal reflux disease (often referred to as GERD)
Irritable/ overactive bladder
Pelvic pain
Temporomandibular disorder - often called TMJ
Diagnostic Tests: What are some additional diagnostic tests that can be done to illuminate the
diagnosis? For example, when you injure your ankle, they take an x-ray to determine if it is broken
or sprained.
There is no test to diagnosis fibromyalgia. However, a provider may order you to get testing to rule
out other disorders. They will also require a physical examination and you to meet certain criteria
for diagnosis, such as fatigue, waking unrefreshed, and cognitive problem. Also, no other health
problem to explain pain that is occurring (Amigues M.D., 2019).
