Blood Flow Through the Heart
Blood Flow Through the Heart samer kareem 6,329 Views • 2 years ago

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

Vomiting and Diarrhea in Kids

Diarrhea in Children: Common Causes and Treatments Diarrhea is the body's way of ridding itself of germs, and most episodes last a few days to a week. Diarrhea often occurs with fever, nausea, vomiting, cramps, and dehydration. Some of the most common reasons kids get diarrhea include: Infection from viruses like rotavirus, bacteria like salmonella and, rarely, parasites like giardia. Viruses are the most common cause of a child's diarrhea. Along with loose or watery stools, symptoms of a viral gastroenteritis infection often include vomiting, stomachache, headache, and fever. When treating viral gastroenteritis -- which can last 5-14 days -- it's important to prevent fluid loss. Offer additional breast milk or an oral rehydration solution (ORS) to infants and young children. Water alone doesn't have enough sodium, potassium, and other nutrients to safely rehydrate very young children. Be sure to talk to your doctor about the amount of fluids your child needs, how to make sure he or she gets them, when to give them, and how to watch for dehydration. Older children with diarrhea can drink anything they like to stay hydrated, including ORS and brand-name products (their names usually end in "lyte"). Popsicles can also be a good way to get fluids into a child who's been vomiting and needs to rehydrate slowly.

Como Aumentar La Libido, Aumentar Niveles De Testosterona, Como Aumentar El Deseo Masculino ---- http://aumentar-testosterona.good-info.co/ --- ¿Se puede tener una erección con bajos niveles de testosterona? Mi libido está quedando atrás y estoy teniendo dificultades para conseguir una erección, así que estoy tratando de averiguar qué está pasando aquí. La disfunción eréctil rara vez es causada sólo por la deficiencia de testosterona. Por lo general es un grupo de cosas que funcionan en concierto juntos, que se alimentan entre sí, que conducen a la incapacidad del hombre para lograr una erección. La aterosclerosis (estrechamiento y endurecimiento de las arterias) es uno de los mayores impulsores de la disfunción eréctil, pero estas arterias dañadas no aparecen de la nada. Otras cosas tienen que estar sucediendo en el cuerpo para que ésta aterosclerosis pase, y como estamos a punto de ver, estas otras cosas contribuyen al problema también. Así que vamos a repasar esta lista… Nivel de azúcar alto – baja testosterona y disfunción eréctil La azúcar elevada en la sangre es un arma de doble filo, porque los hombres que sufren de esta condición son mucho más propensos a ser afectados por la disfunción eréctil y la testosterona baja. Una Investigación de John Hopkins encontró que las ratas diabéticas presentaron una respuesta eréctil 30% inferior, sus erecciones fueron como máximo 40% más pequeñas y las erecciones tomaron 70% más tiempo para lograrse en comparación con los controles que no eran diabéticos. Otros estudios han confirmado que los hombres con diabetes tipo 2 son dos veces más propensos a sufrir de disfunción eréctil, y la condición les golpeará una década antes, en comparación con los hombres sin tipo 2. Este vínculo es tan fuerte porque el azúcar en la sangre hace un daño directo a las arterias cuando se tiene demasiado de él, y las arterias en el pene suelen ser afectados en primer lugar, porque son muy pequeñas y estrechas. Por lo tanto, tiene todo el sentido que éstas pueden dañarse primero. El ejercicio que baja la testosterona haga click aqui http://aumentar-testosterona.good-info.co/

Gastric Bypass Surgery | Duke Health
Gastric Bypass Surgery | Duke Health Surgeon 38 Views • 2 years ago

Gastric bypass, also called Roux-en-Y gastric bypass surgery, is considered a “metabolic” procedure because it changes how your body absorbs fat, calories and nutrients. This metabolic change occurs because your gastrointestinal tract is altered when your gastric bypass surgeon attaches the smaller section of your stomach directly to your small intestine. As a result, your appetite changes and you feel full faster.

Endometrial Polyp
Endometrial Polyp samer kareem 20,625 Views • 2 years ago

Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps). Uterine polyps range in size from a few millimeters — no larger than a sesame seed — to several centimeters — golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.

What is Mohs Surgery?
What is Mohs Surgery? Surgeon 59 Views • 2 years ago

Mohs surgery is a procedure used to remove skin cancers (most commonly basal and squamous cell carcinoma and melanoma) in a way that preserves a maximum amount of healthy tissue. It is useful for skin cancers when:

(1) the location of the cancer is near sensitive areas, like the fingers or face;
(2) earlier treatments have not worked;
(3) a skin cancer is large; and
(4) regular surgery is less likely to remove the cancer.

This procedure video illustrates the procedure on 2 patients with basal cell carcinoma. Click https://ja.ma/3b4scuY to learn more.

Bone Pain Causes
Bone Pain Causes samer kareem 4,554 Views • 2 years ago

Bone pain: Pain is the most common sign of bone cancer, and may become more noticeable as the tumor grows. Bone pain can cause a dull or deep ache in a bone or bone region (e.g., back, pelvis, legs, ribs, arms). Early on, the pain may only occur at night, or when you are active.

Cushing's Disease
Cushing's Disease samer kareem 5,949 Views • 2 years ago

Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.

Scoliosis
Scoliosis samer kareem 18,791 Views • 2 years ago

If you look at someone’s back, you’ll see that the spine runs straight down the middle. When a person has scoliosis, their backbone curves to the side. The angle of the curve may be small, large or somewhere in between. But anything that measures more than 10 degrees is considered scoliosis. Doctors may use the letters “C” and “S” to describe the curve of the backbone. You probably don’t look directly at too many spines, but what you might notice about someone with scoliosis is the way they stand. They may lean a little or have shoulders or hips that look uneven. What Causes Scoliosis? In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,323 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

CPAP demonstration

CPAP is a treatment that uses mild air pressure to keep your breathing airways open. It involves using a CPAP machine that includes a mask or other device that fits over your nose or your nose and mouth, straps to position the mask, a tube that connects the mask to the machine’s motor, and a motor that blows air into the tube. CPAP is used to treat sleep-related breathing disorders including sleep apnea. It also may be used to treat preterm infants who have underdeveloped lungs.
