Difference between arteriosclerosis and atherosclerosis
Difference between arteriosclerosis and atherosclerosis samer kareem 1,775 Views • 2 years ago

Arteriosclerosis occurs when the blood vessels that carry oxygen and nutrients from your heart to the rest of your body (arteries) become thick and stiff — sometimes restricting blood flow to your organs and tissues. Healthy arteries are flexible and elastic, but over time, the walls in your arteries can harden, a condition commonly called hardening of the arteries. Atherosclerosis is a specific type of arteriosclerosis, but the terms are sometimes used interchangeably. Atherosclerosis refers to the buildup of fats, cholesterol and other substances in and on your artery walls (plaques), which can restrict blood flow. These plaques can burst, triggering a blood clot. Although atherosclerosis is often considered a heart problem, it can affect arteries anywhere in your body. Atherosclerosis may be preventable and is treatable.

Folic Acid & Pregnancy
Folic Acid & Pregnancy samer kareem 1,624 Views • 2 years ago

If you're pregnant or might become pregnant, it's critically important to get enough folic acid, the synthetic form of vitamin B9, also known as folate. Folic acid helps prevent neural tube defects (NTDs) – serious birth defects of the spinal cord (such as spina bifida) and the brain (such as anencephaly).

Blood Viscosity
Blood Viscosity samer kareem 1,291 Views • 2 years ago

When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

Squamous Cell Carcinoma of Skin
Squamous Cell Carcinoma of Skin samer kareem 1,472 Views • 2 years ago

Squamous cell carcinomas typically appear as persistent, thick, rough, scaly patches that can bleed if bumped, scratched or scraped. They often look like warts and sometimes appear as open sores with a raised border and a crusted surface. In addition to the signs of SCC shown here, any change in a preexisting skin growth, such as an open sore that fails to heal, or the development of a new growth, should prompt an immediate visit to a physician.

How to use Ultrasound in Pregnancy
How to use Ultrasound in Pregnancy M_Nabil 21,658 Views • 2 years ago

A prenatal ultrasound (also called a sonogram) is a noninvasive diagnostic test that uses sound waves to create a visual image of your baby, placenta, and uterus, as well as other pelvic organs. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby's health. During the test, an ultrasound technician (sonographer) transmits high-frequency sound waves through your uterus that bounce off your baby. A computer then translates the echoing sounds into video images that reveal your baby's shape, position, and movements. (Ultrasound waves are also used in the handheld instrument called a Doppler that your practitioner uses during your prenatal visits to listen to your baby's heartbeat.) You may have an early ultrasound at your practitioner's office at 6 to 10 weeks to confirm and date the pregnancy. Or you may not have one until the standard midpregnancy ultrasound between 16 and 20 weeks. That's when you may learn your baby's sex, if you like. (The technician will probably present you with a grainy printout of the sonogram as a keepsake.) You may also have a sonogram as part of a genetic test, such as the nuchal translucency test, chorionic villus sampling, or amniocentesis, or at any other time if there are signs of a problem with your baby. You'll have more frequent ultrasounds if you have diabetes, hypertension, or other medical complications.

Hysterectomy Surgery
Hysterectomy Surgery samer kareem 8,036 Views • 2 years ago

Hysterectomy is the surgical removal of the uterus. It ends menstruation and the ability to become pregnant. Depending on the reason for the surgery, a hysterectomy may also involve the removal of other organs and tissues such as the ovaries and/or fallopian tubes.

Chest Tube Drainage System
Chest Tube Drainage System samer kareem 3,308 Views • 2 years ago

If you’re like me, you probably hook your chest tube up to a Pleur-Evac, put it on the ground, then back away slowly. Who knows what goes on in that mysterious bubbling white box? Hopefully this will post shed some light. Isn’t this just a container for stuff that comes out of the chest? Why does it look so complicated? It’s complicated because the detection/collection of air and fluid require different setups. Most commercial models also allow you to hook the drainage system to wall suction, so you can quickly evacuate the pleural space. This requires its own setup. Because of the need to juggle air, fluid and suction, the most common commercial system includes 3 distinct chambers. If you were to simplify the device, or build one out of spare bottles and tubes, it might look like this:

Pneumoconiosis Disease
Pneumoconiosis Disease samer kareem 1,317 Views • 2 years ago

The most common symptoms of pneumoconiosis are cough and shortness of breath. The risk is generally higher when people have been exposed to mineral dusts in high concentrations and/or for long periods of time. Inadequate or inconsistent use of personal protective equipment (PPE) such as respirators (specially fitted protective masks) is another risk factor since preventing dusts from being inhaled will also prevent pneumoconiosis. Pneumoconiosis does not generally occur from environmental (non-workplace) exposures since dust levels in the environment are much lower.

It involves placing a small, expandable tube called a stent in the narrowed artery. This procedure is also called carotid angioplasty and stenting. There are two carotid arteries-one on each side of the neck-that supply blood to the brain. These arteries can be narrowed and damaged by fatty deposits called plaque.

A hiatal hernia occurs when the upper part of the stomach pushes through an opening in the diaphragm and into the chest cavity. The diaphragm is the thin muscle wall that separates the chest cavity from the abdomen. The opening in the diaphragm is where the esophagus and stomach join.

Hiatal hernias occur when contents of the abdominal cavity protrude through the esophageal hiatus of the diaphragm. Factors that contribute to the development of a hiatal hernia include an enlargement of the esophageal hiatus due to developmental defects, an increased abdominal thoracic pressure gradient, and the depletion of elastic fibers in the phrenoesophageal membrane with aging. There are four different types of hiatal hernias and management varies depending on the type. Type I, also known as a sliding hernia, is a simple displacement of the gastroesophageal junction into the thoracic cavity. The stomach remains in the abdominal cavity. This is the most common type of hiatal hernia, accounting for about 95% of all hiatal hernias. Types II-IV are classified as paraesophageal hernias. Type II occurs when the gastroesophageal junction maintains its position but the gastric fundus herniates through the diaphragmatic hiatus. Type III has both the gastroesophageal junction and the stomach herniate above the diaphragm. When more than 30% of the stomach is herniated into the thoracic cavity, it is termed a “giant” paraesophageal hernia. A patient has a type IV hernia when other organs, such as the colon, in addition to the stomach herniate above the diaphragm.
