Swollen Lymph Nodes

Lymph nodes are part of the lymphatic system and are small glands that filter lymph. These lymph nodes store white blood cells which are responsible for killing invading organisms. They are most commonly found in the armpit, on the neck and under the jaw.

Lymph nodes become swollen in response to illness, infection, or stress. It is a sign that the lymphatic system is working to get rid of pathogens. However, immune system disorders or cancers can also cause the lymph nodes to swell.

A swollen lymph node can take on many different sizes. They are painful to the touch and can also hurt when making certain movements. They are most often accompanied by other symptoms such as fatigue, fever, and chills. If the swollen lymph node does not subside within a few days, it is advisable to see your doctor.

Parkinson's Disease

Parkinson’s disease is a progressive nervous system disorder that affects one’s movements. Parkinson’s disease signs and symptoms are different for every individual and may go unnoticed in the early stage. Symptoms typically start on one side of the body and remain worse on that side even after the symptoms begin appearing in both sides of the body. Generally, the symptoms of Parkinson’s disease include tremors, slowed movement, rigid muscles, impaired posture and balance, loss of automatic movements such as blinking or swinging of arms when walking, and speech and writing changes. Parkinson’s disease occurs when neurons in an area of the brain that controls movement becomes impaired or dies. These neurons normally produce dopamine. As more neurons become impaired or die, the amount of dopamine produced in the body is reduced significantly, causing the movement problems associated with Parkinson’s disease. People with Parkinson’s also lose the nerve endings that produc...

Pompe Disease

Pompe disease is a rare genetic condition where the body is unable to break down complex sugars. This is due to a deficiency in an enzyme called acid alfa glucosidase (GAA). Mutations in the GAA gene causes this disorder and results in a build up of glycogen in cells. Pompe disease can appear in patients from within a few months of birth, at about 1 years old and even during the teenage years. Those with Pompe disease usually inherit the disease from their parents. However, the allele for the disease is recessive, and may not be expressed in the parents. This disease is typically associated with weak muscles, poor muscle tone and an enlarged liver. However, there are many complications with regards to the respiratory system and motor skills which can also develop. Enzyme replacement treatment is used for all Pompe patients. A drug called aglucosidase alfa is given intravenously, which acts as a replacement for GAA. Sources: https://my.clevelandclinic.org/health/disease...
