This is the CT of a 43 year old male patiënt with infected necrotizing pancreatitis that will undergo a VARD procedure; Videoscopic Assisted Retroperitoneal Debridment. Two weeks before this procedure two large bore percutaneous drains were placed in the peripancreatic collection. The patient i...s placed in supine position with the left side 30 degrees elevated. A 5-7 cm subcostal incision is made in the left flank. With help of CT images and by following the percutaneous drain, the subcutaneous tissue and the fascia are dissected and we enter the retroperitoneal peripancreatic collection. First, with a regular suction device any pus encountered is removed. Two long sympathectomy hooks are inserted in order to keep in the incision open. We than insert the zero degree laparoscope. The first necrosis encountered is removed under direct sight with the use of long grasping forceps. Following the percutaneous drain deeper into the cavity, parts of loosely adherent necrotic material are removed. Gently pulling we remove the necrotic tissue. The suction device is helpful in removing any fluid obstructing the view. Complete necrosectomy is not the ultimate aim of this procedure. Only loosely adherent pieces of necrosis are removed thereby keeping the risk of tearing underlying blood vessels to a minimum. In the rare case of extensive bleeding, the retroperitoneal cavity can be easily packed, either awaiting the bleeding to definitely stop or to act as a bridge to angiographic coiling. This patient is now 6 weeks after onset of disease. We always try to postpone surgical intervention, if possible up to 30 days. On the left side of the collection is the percutaneous drain. In this patient the drain had worked well for 2 weeks. When the patient deteriorated again it was decided to perform the VARD procedure. Large pieces of necrotic pancreas can be removed with VARD. This is a big advantage ov VARD over pure endosopic or percutaneous techniques. When all the necrotic tissue is removed we clean the cavity. Two drains are left in situ as a postoperative lavage system. The VARD procedure is performed via a 6 cm incision, which is closed and continuous postoperative lavage started immediately.
Lipomas are slow-growing soft tissue tumours that rarely reach a size larger than 2 cm. Lesions larger than 5 cm, so-called giant lipomas, can occur anywhere in the body but are seldom found in the upper extremities. The authors present their experiences with eight patients having giant lipomas of the upper extremity. In addition, a review of the literature, and a discussion of the appropriate evaluation and management are included.
During root canal treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed with a rubber-like material called gutta-percha. Afterwards, the tooth is restored with a crown or filling for protection.
The purpose of an ELISA is to determine if a particular protein is present in a sample and if so, how much. There are two main variations on this method: you can determine how much antibody is in a sample, or you can determine how much protein is bound by an antibody. The distinction is whether you are trying to quantify an antibody or some other protein. In this example, we will use an ELISA to determine how much of a particular antibody is present in an individuals blood.
ELISAs are performed in 96-well plates which permits high throughput results. The bottom of each well is coated with a protein to which will bind the antibody you want to measure. Whole blood is allowed to clot and the cells are centrifuged out to obtain the clear serum with antibodies (called primary antibodies). The serum is incubated in a well, and each well contains a different serum (see figure below). A positive control serum and a negative control serum would be included among the 96 samples being tested.
A modified radical mastectomy is a procedure in which the entire breast is removed, including the skin, areola, nipple, and most axillary lymph nodes; the pectoralis major muscle is spared. Historically, a modified radical mastectomy was the primary method of treatment of breast cancer. [1, 2] As the treatment of breast cancer evolved, breast conservation has become more widely used. [3, 4] However, mastectomy still remains a viable option for women with breast cancer. [5, 6]
Human immunodeficiency virus infection / acquired immunodeficiency syndrome (HIV/AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV).[1] During the initial infection a person may experience a brief period of influenza-like illness. This is typically followed by a prolonged period without symptoms. As the illness progresses it interferes more and more with the immune system, making people much more likely to get infections, including opportunistic infections, and tumors that do not usually affect people with working immune systems.
HIV is transmitted primarily via unprotected sexual intercourse (including anal and even oral sex), contaminated blood transfusions and hypodermic needles, and from mother to child during pregnancy, delivery, or breastfeeding.[2] Some bodily fluids, such as saliva and tears, do not transmit HIV.[3] Prevention of HIV infection, primarily through safe sex and needle-exchange programs, is a key strategy to control the spread of the disease. There is no cure or vaccine; however, antiretroviral treatment can slow the course of the disease and may lead to a near-normal life expectancy. While antiretroviral treatment reduces the risk of death and complications from the disease, these medications are expensive and may be associated with side effects.
Genetic research indicates that HIV originated in West-central Africa during the early twentieth century.[4] AIDS was first recognized by the Centers for Disease Control and Prevention (CDC) in 1981 and its cause—HIV infection—was identified in the early part of the decade.[5] Since its discovery, AIDS has caused nearly 30 million deaths (as of 2009).[6] As of 2010, approximately 34 million people have contracted HIV globally.[7] AIDS is considered a pandemic—a disease outbreak which is present over a large area and is actively spreading.[8]
HIV/AIDS has had a great impact on society, both as an illness and as a source of discrimination. The disease also has significant economic impacts. There are many misconceptions about HIV/AIDS such as the belief that it can be transmitted by casual non-sexual contact. The disease has also become subject to many controversies involving religion.
Meckel's Diverticulum is a vestigeal remnant of vitellointestinal duct. Its a true diverticulum as it contains all three layers of intestine. It is usually presents at anti mesenteric burder. Usually 2 cm (range 1- 12 cm ) in length, found in 2 % of population , and situated around 2 feet of Ileaocecal junction. 50 % cases it contains gastric mucosa , but may also contain colonic, duodenal or pancreatic mucosa .male : female ration in symptomatic cases is 3 : 1.It may mimic acute appendicitis, so in cases where one is going for surgery for appendicitis , must search for meckel's diverticulum........
An automated external defibrillator or AED is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient,[1] and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm. The first AED was originally designed and created by American biomedical engineer Joshua L. Koelker and Italian emergency medical professional Jordan M. Blondino to allow defibrillation in common public places. AEDs are designed to be simple to use for the layman, and the use of AEDs is taught in many first aid, first responder, and basic life support (BLS) level CPR classes.
