NEURON ACTION POTENTIAL
NEURON ACTION POTENTIAL samer kareem 4,109 Views • 3 years ago

Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

Bigger Muscles?? Victims of Synthol and non-muscle developing methods Doctor 16,542 Views • 3 years ago

Some bodybuilders, particularly at professional level, use substances such as "site enhancement oil", commonly known as synthol, to mimic the appearance of developed muscle where it may otherwise be disproportionate or lagging. This is known as "fluffing". Synthol is 85% oil, 7.5% lidocain, and 7.5% alcohol.Use is legal and many brands are available on the internet.The use of injected oil to enhance muscle appearance had previously been used in the late 19th century before being abandoned due to health risks such as sclerosing lipogranuloma. Its use was revived more recently by bodybuilders. Use can cause pulmonary embolisms, nerve damage, infections, stroke, and the formation of oil-filled oleomas, cysts or ulcers in the muscle. Sesame oil is often used, which can cause allergic reactions such as vasculitis. An aesthetic issue is drooping of muscle under gravity. Surgical methods are also often employed to remove steroid-related gynecomastia in male bodybuilders, and breast implants in female bodybuilders who wish to retain a feminine physique, which can be compromised in terms of breast reduction by intense dieting.

For men, a normal hemoglobin level is typically defined as a level of more than 13.5 gram/100 ml, and in women as hemoglobin of more than 12.0 gram/100 ml. These definitions may vary slightly depending on the source and the laboratory reference used. Continue Reading

People whose back or neck pain has not been relieved by back surgery or other treatments may have another option to consider: spinal cord stimulation. Around the world, some 14,000 patients undergo spinal cord stimulator implants each year. Spinal cord stimulation (SCS) delivers mild electrical stimulation to nerves along the spinal column, modifying or blocking nerve activity in a non-medicinal way to minimize the sensation of pain reaching the brain.

Proximal femur & Hip Fixation
Proximal femur & Hip Fixation samer kareem 2,426 Views • 3 years ago

The lateral approach is used for insertion of fixation devices after closed reduction of a proximal femoral fracture. Reduction of a displaced fracture is usually done with a fracture table, or alternatively a large distractor spanning the hip joint. After satisfactory reduction is confirmed by image intensifier, the lateral approach can be used for insertion of a sliding hip screw or multiple screws. The approach provides limited access to the lateral surface of the femur sufficient for hardware placement. The incision can be extended proximally to accommodate a trochanteric stabilizing plate (TSP), or even anteriorly so that it becomes an anterolateral approach with direct, although limited, access to the femoral neck.

Insertion of a CSF shunt
Insertion of a CSF shunt samer kareem 5,405 Views • 3 years ago

Good abdominal wall closure is one of the basic surgical skills and is a common feature of almost all modern-day CSF shunt operations. The fact that some patients require multiple abdominal operations highlights the need for a simple and effective technique for peritoneal catheter insertion through the abdominal wall and abdominal wall closure. Although technically simple, abdominal wall closure becomes more complex when combined with the requirement to maintain CSF shunt function in cases in which the shunt catheter passes through the abdominal wall into the peritoneal cavity. In this report, the authors describe a simple technique for passing the peritoneal catheter of a ventriculoperitoneal shunt through the abdominal wall on a pathway separate from the fascial opening. This technique minimizes the risk of abdominal wall-related complications and is especially important in high-risk patients such as those with obesity and/or diabetes and in children.

Videoscopic Assisted Retroperitoneal Debridement for infected necrotizing pancreatitis

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.

Bladder Outlet Obstruction Interventions
Bladder Outlet Obstruction Interventions samer kareem 14,419 Views • 3 years ago

The etiology of BOO is diverse and definitely gender specific. Often anatomic causes induce functional abnormality that remains somewhat unique for each individual, regardless of sex. A full appreciation of the possible etiologies of obstruction is necessary in order to identify overt and more subtle scenarios. In women, iatrogenic causes of obstruction are the most common. Other entities account for far fewer of the cases. The obstruction evaluation in women is somewhat more diverse in terms of modalities used, with no single grouping of techniques that are generally apropos. Individualized evaluation remains a tenet of analysis, and urodynamic criteria used to diagnose BOO in women continue to evolve.
