Hepatitis B Symptoms and Treatment
Hepatitis B Symptoms and Treatment samer kareem 1,471 Views • 2 years ago

Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. Risk for chronic infection is related to age at infection: approximately 90% of infected infants become chronically infected, compared with 2%–6% of adults. Chronic Hepatitis B can lead to serious health issues, like cirrhosis or liver cancer. The best way to prevent Hepatitis B is by getting vaccinated.

Acute Respiratory Distress Syndrome Pathophysiology
Acute Respiratory Distress Syndrome Pathophysiology samer kareem 2,168 Views • 2 years ago

ARDS was recognized as the most severe form of acute lung injury (ALI), a form of diffuse alveolar injury. The AECC defined ARDS as an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. The severity of hypoxemia necessary to make the diagnosis of ARDS was defined by the ratio of the partial pressure of oxygen in the patient’s arterial blood (PaO2) to the fraction of oxygen in the inspired air (FiO2). ARDS was defined by a PaO2/FiO2 ratio of less than 200, and in ALI, less than 300. This definition was further refined in 2011 by a panel of experts and is termed the Berlin definition of ARDS. [3] ARDS is defined by timing (within 1 wk of clinical insult or onset of respiratory symptoms); radiographic changes (bilateral opacities not fully explained by effusions, consolidation, or atelectasis); origin of edema (not fully explained by cardiac failure or fluid overload); and severity based on the PaO2/FiO2 ratio on 5 cm of continuous positive airway pressure (CPAP). The 3 categories are mild (PaO2/FiO2 200-300), moderate (PaO2/FiO2 100-200), and severe (PaO2/FiO2 ≤100).

Tooth Filling Procedure
Tooth Filling Procedure samer kareem 6,765 Views • 2 years ago

A filling is a way to restore a tooth damaged by decay back to its normal function and shape. When a dentist gives you a filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay. Materials used for fillings include gold, porcelain, a composite resin (tooth-colored fillings), and an amalgam (an alloy of mercury, silver, copper, tin and sometimes zinc).

Front Tooth Filling
Front Tooth Filling samer kareem 2,144 Views • 2 years ago

Tooth colored composite fillings are chemically bonded to teeth. For this reason, the placement of white fillings does not always require numbing the area being restored. Numbing (anesthetizing) the area is often required if tooth decay has progressed beneath the enamel layer and into the underlying dentin layer which surrounds the nerve of the tooth. Once decay is removed, the tooth is cleaned and a primer (weak acid) is applied to the area being restored. The primer opens pores in the enamel and dentin. A bonding agent is then flowed into the open pores and cured. Curing prepares the bonding agent to adhere to the tooth colored filling material. The filling material is then placed inside the tooth. After shaping the tooth colored filling material to resemble the natural anatomy of your tooth it is hardened by curing with a strong curing light. Once the white filling hardens, your bite will be checked to make sure your teeth fit together properly. If the tooth filling extends into the space between your teeth your dentist will also make sure you can floss between your teeth properly. Adjustments will be made if necessary followed by smoothing and polishing of your new filling..

Tongue and lip-tie are common causes of nipple pain, uneven breast drainage, slow weight gain and low milk supply. Many physicians do not properly assess for tongue or lip-tie or recognize their impact on the breastfeeding relationship, leaving babies vulnerable to early weaning. Ultrasound studies have shown that the tongue movements used by tongue-tied babies are qualitatively different from those used by by babies who are not tongue-tied. These movements are not as effective at removing milk from the breast and can cause significant pain and nipple damage. In these studies, tongue-tied babies also did not draw the nipple as deeply into the mouth as babies who were not tongue-tied.

Fertilization and Implantation in human
Fertilization and Implantation in human samer kareem 3,112 Views • 2 years ago

Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.

Paracentesis is a procedure to take out fluid that has collected in the belly (peritoneal fluid). This fluid buildup is called ascites camera.gif. Ascites may be caused by infection, inflammation, an injury, or other conditions, such as cirrhosis or cancer. The fluid is taken out using a long, thin needle put through the belly. The fluid is sent to a lab and studied to find the cause of the fluid buildup. Paracentesis also may be done to take the fluid out to relieve belly pressure or pain in people with cancer or cirrhosis.

Oral therapy has potential for symptom relief. It has the advantage of no surgery. Disadvantages include ongoing medication therapy, risks of side effects, high out of pocket cost, and sometimes over time effectiveness diminishes. Certain men also do not like to take medications. This is the most common way to treat BPH. Medicines like Flomax, Cardura, Hytrin and Uroxatral have proven to be effective in the treatment of most cases. Alpha Blockers relieve the obstruction by trying to stop the process by which the construction occurs. They basically relax the smooth muscle cells in the prostate to relieve urinary obstruction. Like most medicines side effects can occur. They are mild in most cases and include dizziness on standing, feeling fatigued, loss of ability to ejaculate with orgasm.

Getting Baby Latched On to the Breast
Getting Baby Latched On to the Breast samer kareem 20,989 Views • 2 years ago

In breastfeeding, the latch is the moment everything comes together: Your baby takes a big mouthful of your nipple and areola (or "latches on"), begins to suck, and draws out your milk. When your baby has established a good latch, your nipple soreness is minimized and your little one gets the nourishment he needs. How do you pull all that off? First and most important, have faith in yourself and your baby. "Babies are designed to breastfeed," says Emily Pease, R.N., international board certified lactation consultant (IBCLC), of Swedish Hospital's Breastfeeding Center in Seattle. "They are born with instincts that help them find Mom's breast and latch on often with very little assistance. And if problems do come up, there are lots of ways to troubleshoot." Here are more steps to get a good latch right from the start.

Bariatric Surgery Procedures
Bariatric Surgery Procedures samer kareem 5,521 Views • 2 years ago

Bariatric surgical procedures cause weight loss by restricting the amount of food the stomach can hold, causing malabsorption of nutrients, or by a combination of both gastric restriction and malabsorption. Bariatric procedures also often cause hormonal changes. Most weight loss surgeries today are performed using minimally invasive techniques (laparoscopic surgery). The most common bariatric surgery procedures are gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch. Each surgery has its own advantages and disadvantages.
