Total Anomalous Pulmonary Venous Return
Total Anomalous Pulmonary Venous Return samer kareem 4,638 Views • 2 years ago

Total anomalous pulmonary venous return (TAPVR) is a rare congenital malformation in which pulmonary veins that return oxygen-rich blood from the lungs do not connect normally to the left atrium. Instead all four pulmonary veins drain abnormally to the right atrium. Heart models and animation were developed by the Cincinnati Children's Heart Institute in conjunction with Cincinnati Children's Critical Care Media Lab.

If you have been diagnosed with diabetes, you may feel overwhelmed by all the new information you have learned and will continue to learn about managing your diabetes. You already know your main goal should be to get your blood glucose (sugar) levels under control in order to increase your chances of a complication-free life. Many people know this, but need to know how to achieve good diabetes management, while balancing the day-to-day demands of diabetes with other life demands. An insulin pump can help you manage your diabetes. By using an insulin pump, you can match your insulin to your lifestyle, rather than getting an insulin injection and matching your life to how the insulin is working. When you work closely with your diabetes care team, insulin pumps can help you keep your blood glucose levels within your target ranges. People of all ages with type 1 diabetes use insulin pumps and people with type 2 diabetes have started to use them as well. - See more at: http://www.diabetes.org/living-with-diabetes/treatment-and-care/medication/insulin/how-do-insulin-pumps-work.html?referrer=https://www.google.com/#sthash.XD56v351.dpuf

Intra Oral Camera Mohamed 12,962 Views • 2 years ago

Walk through your mouth with Intra Oral Technology and see the unseen! Most of us can't really see what is going on in our mouths because it is a very small, and shadowed area. What we don't know is that many situations and conditions in the mouth and painless and not always visible to the naked eye.

The Intra Oral Camera is a fascinating innovation in dentistry that allows the client and our clinicians to look deep into the mouth and observe the teeth at a very close angle. This wand like camera which transfers images to a television, can see so close to a tooth that it can see mini fractures, chips, secondary decay, wear down of the teeth, damaged and broken fillings and crowns and even gum disease. At Yaletown we believe that people can decide what is best for their own health. The Intra Oral Camera is a wonderful educational tool for clients so they can learn about their mouths to help them on their journey to overall dental wellness.

Cardiovascular disease (CVD) is a general term that describes a disease of the heart or blood vessels. Blood flow to the heart, brain or body can be reduced as the result of a blood clot (thrombosis), or by a build-up of fatty deposits inside an artery that cause the artery to harden and narrow (atherosclerosis).

How is HIV Transmitted?
How is HIV Transmitted? samer kareem 1,525 Views • 2 years ago

-Almost all the cases of occupational transmission of HIV have been due to transmission via exposure to blood and certain body fluids. The body fluids wherein standard precautions have been recommended include semen, vaginal secretions, and any other body fluid containing visible blood. Other standard precautions, according to the Center for Disease Control and Prevention (CDC), also apply to cerebrospinal, peritoneal, pleural, pericardia!, synovial fluid, or any other tissue, even though the epidemiologic data regarding the risk of HIV transmission from these fluids is insufficient. Standard precautions do not apply to urine, sweat, tears, sputum, vomitus, and nasal secretions or feces, as long as there is no gross visible blood. The occupational transmission of HIV has never been documented from the above sources.

Cerebral Venous Sinus Thrombosis
Cerebral Venous Sinus Thrombosis samer kareem 5,799 Views • 2 years ago

Thrombosis of the venous channels in the brain is an uncommon cause of cerebral infarction relative to arterial disease, but it is an important consideration because of its potential morbidity. (See Prognosis.) Knowledge of the anatomy of the venous system is essential in evaluating patients with cerebral venous thrombosis (CVT), since symptoms associated with the condition are related to the area of thrombosis. For example, cerebral infarction may occur with cortical vein or sagittal sinus thrombosis secondary to tissue congestion with obstruction. (See Presentation.) Lateral sinus thrombosis may be associated with headache and a pseudotumor cerebri–like picture. Extension into the jugular bulb may cause jugular foramen syndrome, while cranial nerve palsies may be seen in cavernous sinus thrombosis as a compressive phenomenon. Cerebral hemorrhage also may be a presenting feature in patients with venous sinus thrombosis. (See Presentation.) Imaging procedures have led to easier recognition of venous sinus thrombosis (see the images below), offering the opportunity for early therapeutic measures. (See Workup.) Left lateral sinus thrombosis demonstrated on magn Left lateral sinus thrombosis demonstrated on magnetic resonance venography (MRV). This 42-year-old woman presented with sudden onset of headache. Physical examination revealed no neurologic abnormalities. View Media Gallery Axial view of magnetic resonance (MR) venogram dem Axial view of magnetic resonance (MR) venogram demonstrating lack of flow in transverse sinus. View Media Gallery The following guidelines for CVT have been provided by the American Heart Association and the American Stroke Association [1] : In patients with suspected CVT, routine blood studies consisting of a complete blood count, chemistry panel, prothrombin time, and activated partial thromboplastin time should be performed. Screening for potential prothrombotic conditions that may predispose a person to CVT (eg, use of contraceptives, underlying inflammatory disease, infectious process) is recommended in the initial clinical assessment. Testing for prothrombotic conditions (including protein C, protein S, or antithrombin deficiency), antiphospholipid syndrome, prothrombin G20210A mutation, and factor V Leiden can be beneficial for the management of patients with CVT. Testing for protein C, protein S, and antithrombin deficiency is generally indicated 2-4 weeks after completion of anticoagulation. There is a very limited value of testing in the acute setting or in patients taking warfarin. In patients with provoked CVT (associated with a transient risk factor), vitamin K antagonists may be continued for 3-6 months, with a target international normalized ratio of 2.0-3.0. In patients with unprovoked CVT, vitamin K antagonists may be continued for 6-12 months, with a target international normalized ratio of 2.0-3.0. For patients with recurrent CVT, venous thromboembolism (VTE) after CVT, or first CVT with severe thrombophilia (ie, homozygous prothrombin G20210A; homozygous factor V Leiden; deficiencies of protein C, protein S, or antithrombin; combined thrombophilia defects; or antiphospholipid syndrome), indefinite anticoagulation may be considered, with a target international normalized ratio of 2.0-3.0. For women with CVT during pregnancy, low-molecular-weight heparin (LMWH) in full anticoagulant doses should be continued throughout pregnancy, and LMWH or vitamin K antagonist with a target international normalized ratio of 2.0-3.0 should be continued for ≥6 weeks postpartum (for a total minimum duration of therapy of 6 months). It is reasonable to advise women with a history of CVT that future pregnancy is not contraindicated. Further investigations regarding the underlying cause and a formal consultation with a hematologist or maternal fetal medicine specialist are reasonable. It is reasonable to treat acute CVT during pregnancy with full-dose LMWH rather than unfractionated heparin. For women with a history of CVT, prophylaxis with LMWH during future pregnancies and the postpartum period is reasonable.

Ducts are drainage routes; the drainage channels from the liver are called bile or biliary ducts. The pancreatic duct is the drainage channel from the pancreas.

Constrictive pericarditis versus restrictive cardiomyopathy
Constrictive pericarditis versus restrictive cardiomyopathy samer kareem 6,795 Views • 2 years ago

Constrictive pericarditis is the result of scarring and consequent loss of the normal elasticity of the pericardial sac. This leads to impairment of ventricular filling in mid and late diastole. As a result, the majority of ventricular filling occurs rapidly in early diastole and the ventricular volume does not increase after the end of the early filling period. Restrictive cardiomyopathy is characterized by a nondilated rigid ventricle, resulting in severe diastolic dysfunction and restrictive filling that produces hemodynamic changes similar to those in constrictive pericarditis. Constrictive pericarditis and restrictive cardiomyopathy both lead to diastolic heart failure with normal (or near normal) systolic function, and characteristically abnormal ventricular filling that results in similar clinical and hemodynamic features. However, because of their markedly different treatments, differentiating between the two conditions is critical. In some patients, the correct diagnosis may be readily suggested from the history or routine diagnostic testing. In others, however, this differentiation cannot be diagnosed before biopsy or even surgical exploration.

Psychological Erectile Dysfunction
Psychological Erectile Dysfunction samer kareem 1,733 Views • 2 years ago

Erectile dysfunction (ED) is the inability to get or keep an erection firm enough for sexual function. It’s a common sexual problem, affecting as many as 30 million men in the United States. Most cases of ED have a physical cause, such as heart disease, diabetes, and obesity. Lifestyle choices like smoking and drinking excessive amounts of alcohol can also lead to ED. But for some men, psychological issues are the root of the problem.

Worst Plantar Warts & Plantar Wart Removal
Worst Plantar Warts & Plantar Wart Removal samer kareem 60,060 Views • 2 years ago

Plantar warts are hard, grainy growths that usually appear on the heels or balls of your feet, areas that feel the most pressure. This pressure also may cause plantar warts to grow inward beneath a hard, thick layer of skin (callus). Plantar warts are caused by the human papillomavirus (HPV). The virus enters your body through tiny cuts, breaks or other weak spots on the bottom of your feet. Most plantar warts aren't a serious health concern and may not require treatment. But plantar warts can cause discomfort or pain. If self-care treatments for plantar warts don't work, you may want to see your doctor to have them removed.

Microsurgical bipolar cautery tonsillectomy compares favorably with traditional techniques in terms of intraoperative bleeding, postoperative pain, otalgia, and hemorrhage. This technique combines the hemostatic advantage of cautery dissection, the excellent visualization achieved by a microscope, and, with the use of a video, greatly improves the physician's ability to teach how to perform a tonsillectomy.

Caesarean section for a breech
Caesarean section for a breech Mohamed Ibrahim 26,552 Views • 2 years ago

Caesarean section is the most common way to deliver a breech baby in the USA, Australia, and Great Britain. Like any major surgery, it involves risks. Maternal mortality is increased by a Caesarean section, but still remains a rare complication in the First World. Third World statistics are dramatically different, and mortality is increased significantly. There is remote risk of injury to the mother’s internal organs, injury to the baby, and severe hemorrhage requiring hysterectomy with resultant infertility. More commonly seen are problems with noncatastrophic bleeding, postoperative infection and wound healing problems. It should be added that the increase in maternal mortality rates could be slightly skewed due to the fact that Caesarean sections are often used during high-risk pregnancies and/or when mortality is already a strong possibility.

One large study has confirmed that elective cesarean section has lower risk to the fetus and a slightly increased risk to the mother, than planned vaginal delivery of the breech however elements of the methodology used have undergone some criticism.

The same birth injuries that can occur in vaginal breech birth may rarely occur in Caesarean breech delivery. A Caesarean breech delivery is still a breech delivery. However the soft tissues of the uterus and abdominal wall are more forgiving of breech delivery than the hard bony ring of the pelvis. If a Caesarean is scheduled in advance (rather than waiting for the onset of labor) there is a risk of accidentally delivering the baby too early, so that the baby might have complications of prematurity. The mother’s subsequent pregnancies will be riskier than they would be after a vaginal birth (uterine rupture). The presence of a uterine scar will be a risk factor for any subsequent pregnancies.

A spontaneous vaginal delivery (SVD) occurs when a pregnant woman goes into labor with or without use of drugs or techniques to induce labor, and delivers her baby in the normal manner, without forceps, vacuum extraction, or a cesarean section. Assisted vaginal delivery (AVD) occurs when a pregnant woman goes into labor with or without the use of drugs or techniques to induce labor, and requires the use of special instruments such as forceps or a vacuum extractor to deliver her baby vaginally.

At one time, women who had delivered by cesarean section in the past would usually have another cesarean section for any future pregnancies. The rationale was that if allowed to labor, many of these women with a scar in their uterus would rupture the uterus along the weakness of the old scar. Over time, a number of observations have become apparent: Most women with a previous cesarean section can labor and deliver vaginally without rupturing their uterus. Some women who try this will, in fact, rupture their uterus. When the uterus ruptures, the rupture may have consequences ranging from near trivial to disastrous. It can be very difficult to diagnose a uterine rupture prior to observing fetal effects (eg, bradycardia). Once fetal effects are demonstrated, even a very fast reaction and nearly immediate delivery may not lead to a good outcome. The more cesarean sections the patient has, the greater the risk of subsequent rupture during labor. The greatest risk occurs following a “classical” cesarean section (in which the uterine incision extends up into the fundus.) The least risk of rupture is among women who had a low cervical transverse incision. Low vertical incisions probably increase the risk of rupture some, but usually not as much as a classical incision. Many studies have found the use of oxytocin to be associated with an increased risk of rupture, either because of the oxytocin itself, or perhaps because of the clinical circumstances under which it would be contemplated. Pain medication, including epidural anesthetic, has not resulted greater adverse outcome because of the theoretical risk of decreasing the attendant’s ability to detect rupture early. The greatest risk of rupture occurs during labor, but some of the ruptures occur prior to the onset of labor. This is particularly true of the classical incisions. Overall successful vaginal delivery rates following previous cesarean section are in the neighborhood of 70 This means that about 30of women undergoing a vaginal trial of labor will end up requiring a cesarean section. Those who undergo cesarean section (failed VBAC) after a lengthy labor will frequently have a longer recovery and greater risk of infection than had they undergone a scheduled cesarean section without labor. Women whose first cesarean was for failure to progress in labor are only somewhat less likely to be succesful in their quest for a VBAC than those with presumably non-recurring reasons for cesarean section. For these reasons, women with a prior cesarean section are counseled about their options for delivery with a subsequent pregnancy: Repeat Cesarean Section, or Vaginal Trial of Labor. They are usually advised of the approximate 70successful VBAC rate (modified for individual risk factors). They are counseled about the risk of uterine rupture (approximately 1in most series), and that while the majority of those ruptures do not lead to bad outcome, some of them do, including fetal brain damage and death, and maternal loss of future childbearing. They are advised of the usual surgical risks of infection, bleeding, anesthesia complications and surgical injury to adjacent structures. After counseling, many obstetricians leave the decision for a repeat cesarean or VBAC to the patient. Both approaches have risks and benefits, but they are different risks and different benefits. Fortunately, most repeat cesarean sections and most vaginal trials of labor go well, without any serious complications. For those choosing a trial of labor, close monitoring of mother and baby, with early detection of labor abnormalities and preparation for

Female Pelvic Floor Part 1
Female Pelvic Floor Part 1 Mohamed 71,706 Views • 2 years ago

The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus, and associated connective tissue which span the area underneath the pelvis. The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. The pelvic floor separates the pelvic cavity above from the perineal region (including perineum) below.

The right and left levator ani lie almost horizontally in the floor of the pelvis, separated by a narrow gap that transmits the urethra, vagina, and anal canal. The levator ani is usually considered in three parts: pubococcygeus, puborectalis, and iliococcygeus. The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during parturition. Some fibers are inserted into the prostate, urethra, and vagina. The right and left puborectalis unite behind the anorectal junction to form a muscular sling . Some regard them as a part of the sphincter ani externus. The iliococcygeus, the most posterior part of the levator ani, is often poorly developed.

The coccygeus, situated behind the levator ani and frequently tendinous as much as muscular, extends from the ischial spine to the lateral margin of the sacrum and coccyx.

The pelvic cavity of the true pelvis has the pelvic floor as its inferior border (and the pelvic brim as its superior border.) The perineum has the pelvic floor as its superior border.

Some sources do not consider “pelvic floor” and “pelvic diaphragm” to be identical, with the “diaphragm” consisting of only the levator ani and coccygeus, while the “floor” also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diaphragm. In practice, the two terms are often used interchangeably.

Inferiorly, the pelvic floor extends into the anal triangle.
