Laryngeal Cancer is a cancer that affects the larynx and is commonly known as the cancer of the voice box. Larynx is a part of the throat between the trachea and the base tongue. It contains the vocal cords and is divided into three parts. Supraglottis is the upper part of the larynx that is above the vocal cords and includes the epiglottis. Glottis is the middle part of the larynx and this is where the vocal cords are located. Subglottis is the lower part of the larynx which is located between the trachea and the vocal cords. When cancer cells are formed in the larynx tissues, it is known as laryngeal cancer. Most cancer cells are formed in the thin and flat squamous cells that line the inside of the larynx. This type of cancer comes under the category of head and neck cancer. Laryngeal cancer is treatable, but the effectiveness of the treatment is based upon several factors. The stage of the cancer is the most important factor to consider, along with the exact location and the size of it. A person’s general health, age, and certain other body parameters also determine the effectiveness of the treatment. All these factors affect the patient’s chances of recovery.

Lipid disorders are a group of medical conditions which occur due to increased levels of fatty substances like cholesterol and triglycerides in a person’s blood. High cholesterol may lead to development of fatty deposits in the blood vessels which limits the flow of blood through the arteries. Lipid disorders increase the probability of heart disease and may even lead to stroke. The types of cholesterol are: High-Density Lipoprotein (HDL) Cholesterol: Lipoproteins are substances that carry cholesterol in the blood. HDL cholesterol is also known as “good’ cholesterol because it helps in removing excess cholesterol and preventing cholesterol build up in the blood vessels. This decreases the risk of heart disease. Low-Density Lipoprotein (LDL) Cholesterol: LDL cholesterol is commonly known as bad cholesterol. It grows in the inner walls of the arteries contributing to the formation of cholesterol plaques. Cholesterol plaques can block up arteries resulting in the hardening and narrowing of arteries (atherosclerosis).

Liver cancer, or hepatocellular carcinoma, is one of the deadliest cancers known. It involves growth of cancerous cells called hepatocytes inside the liver. The cancer cells are known to spread from one body part to another. In case of liver cancer, it is not necessary that the cancerous cells are restricted to the liver only. After affecting the area, the cells can move to other body part such as the breast, colon, or even the lungs. Metastatic liver cancer is also a type of liver cancer found in liver but has originated in some other region. The origin organ can be the lungs, colon, bladder, pancreas, kidney, ovary, breast, stomach, or the uterus. These organs are more prone to getting affected and then spreading the infected cells to the liver. Other than the common liver cancer (hepatocellular carcinoma), there are other types of liver cancers namely, intrahepatic cholangiocarcinoma and hepatoblastoma. They occur when the cancer cells develop in the ducts of the liver.

Liver cirrhosis is a slow-developing disease in which normal tissues of the liver are replaced by abnormal/scar tissues. The disease prevents the normal flow of blood through the liver and stops the liver from functioning properly, leading to a long-term damage. Cirrhosis even affects the abdominal blood vessels, and the huge portal vein, which transports blood from the intestines and spleen through the liver. Cirrhosis causes ailments such as jaundice, excessive itching, and fatigue. Mild cirrhosis can be easily treated, but advanced stages may cause widespread liver damage.

The electrical system of your heart controls your pulses by using two factors. One is your heart rate or the number of times your heart beats per minute. The second factor is the rhythm of your heart or the synchronization between the two atria and the two ventricles of your heart. To achieve these, it is the duty of the electrical system to maintain a steady heart rate and rhythm in the sinus. The sinus controls the contraction of atria and ventricles. Q and T waves refer to the electrical impulses that are the cause of contraction and expansion of the chambers of the heart. ‘QT interval’ is the time lapse between the start of the Q wave and the end of the T wave, in the electrical cycle of the heart. On an average, the QT interval lasts from 0.2 to 0.4 seconds. If the QT interval is longer, it could cause imbalances in the rhythm of the heart, called arrhythmia. This phenomenon is called ‘Long QT syndrome’. If the QT interval is shorter, it might indicate that the blood has high levels of calcium content. This is referred to as ‘Short QT syndrome’.
