Closure of Wound by Stress Relaxation
Closure of Wound by Stress Relaxation samer kareem 1,750 Views • 3 years ago

Stress-relaxation is a well-established mechanism for laboratory skin stretching, with limited clinical application in conventional suturing techniques due to the inherent, concomitant induction of ischemia, necrosis and subsequent suture failure. Skin defects that cannot be primarily closed are a common difficulty during reconstructive surgery. The TopClosure tension-relief system (TRS) is a novel device for wound closure closure, providing secured attachment to the skin through a wide area of attachment, in an adjustable manner, enabling primary closure of medium to large skin defects. The aim of this study was to evaluate the efficiency of the TopClosure TRS as a substitute for skin grafting and flaps for primary closure of large soft tissue defects by stress-relaxation. We present three demonstrative cases requiring resection of large to huge tumors customarily requiring closure by skin graft or flaps. TRS was applied during surgery serving as a tension-relief platform for tension sutures, to enable primary skin-defect closure by cycling of stress-relaxation, and following surgery as skin-secure system until complete wound closure. All skin defects ranging from 7 to 26 cm in width were manipulated by the TRS through stress-relaxation, without undermining of skin, enabling primary skin closure and eliminating the need for skin grafts and flaps. Immediate wound closure ranged 26 to 135 min. TRS was applied for 3 to 4 weeks. Complications were minimal and donor site morbidity was eliminated. Surgical time, hospital stay and costs were reduced and wound aesthetics were improved. In this case series we present a novel technology that enables the utilization of the viscoelastic properties of the skin to an extreme level, extending the limits of primary wound closure by the stress-relaxation principle. This is achieved via a simple device application that may aid immediate primary wound closure and downgrade the complexity of surgical procedures for a wide range of applications on a global scale.

Doctors give soldier New Ear after growing it in her arm
Doctors give soldier New Ear after growing it in her arm Mohamed Ibrahim 1,261 Views • 3 years ago

Shamika Burrage survived a near-fatal car accident two years ago, but not without losing something pretty important: her left ear. Now, thanks to a novel procedure performed at an Army medical center in Texas, Burrage is getting that ear back in a most unusual way. Plastic surgeons harvested cartilage from Burrage's ribs to create a new ear and then grew it under the skin of her forearm. Then the doctors at William Beaumont Army Medical Center in El Paso successfully transplanted the ear from her arm to her head. The technique -- a first time in the Army -- is called prelaminated forearm free flap, said Lt. Col. Owen Johnson III, chief of plastic and reconstructive surgery at William Beaumont Army Medical Center. Some of the big advantages of it is that it reduced the chance of more scarring around Burrage's ear. Also, growing the ear under the skin of her forearm allows new blood vessels to form. "(The ear) will have fresh arteries, fresh veins and even a fresh nerve so she'll be able to feel it," Johnson said on the US Army's website. Burrage, a 21-year-old private, still has to endure two more surgeries, but she's feeling more optimistic about the future than ever in the years since her accident. "It's been a long process for everything, but I'm back," said Burrage.

Neck Examination - Cervical Spine Assessment - Clinical Skills - Dr Gill

Compose a new pain within athletes is cervical spine discomfort, thankfully in the vast majority of cases when the neck is examined the cause of the neck pain is found to be muscular.

However, pain can also refer from the neck to the arm, in which case it is important to be able to assess for cervical radiculopathy prior to gaining more information which may indicate an MRI is needed

We assess for radiculopathy by doing Spurling's test, an often overlooked part of the neck examination, but it should be included for completeness and reassurance of the patient - not forgetting the athlete or not, neck pain can be a considerable source of distress, so it's vital to be able to get information from the neck examination which allows you to safely reassure a patient when appropriate, or comment that neck exam found evidence that needs further investigation

Superior Capsular Reconstruction
Superior Capsular Reconstruction samer kareem 1,404 Views • 3 years ago

Superior capsule reconstruction (SCR) is a promising alternative treatment for irreparable posterosuperior rotator cuff tears (Figure 1). It utilizes a graft from the superior glenoid to the greater tuberosity to stabilize the humeral head. In a study by Mihata and colleagues of 23 patients who underwent SCR with a fascia lata autograft at a minimum of 2 years follow-up, the American Shoulder and Elbow Surgeons (ASES) score improved significantly from 23.5 preoperatively to 92.9. Postoperative MRI showed 83% of patients had intact reconstructions with no progression of muscle atrophy.

This video shows Prof Dan Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO performing a ReLEx SMILE keyhole LASIK procedure using the latest surgical instrument that he helped to develop (Malosa MMSU1297 - Reinstein Lenticule Separator: http://www.malosa.com/en/reinstein-le...). This instrument enables the procedure to be performed with one instrument, through one 2mm incision, using only one sweep per plane, and taking about 30 seconds to separate and withdraw the lenticule, improving day 1 uncorrected vision over other lenticule extraction techniques that require more corneal manipulation.

Bone Scan Introduction
Bone Scan Introduction Mohamed 17,994 Views • 3 years ago

A Bone scan or bone scintigraphy is a nuclear scanning test to find certain abnormalities in bone which are triggering the bone's attempts to heal. It is primarily used to help diagnose a number of conditions relating to bones, including: cancer of the bone or cancers that have spread (metastasized) to the bone, locating some sources of bone inflammation (e.g. bone pain such as lower back pain due to a fracture), the diagnosis of fractures that may not be visible in traditional X-ray images, and the detection of damage to bones due to certain infections and other problems.

Nuclear medicine bone scans are one of a number of methods of bone imaging, all of which are used to visually detect bone abnormalities. Such imaging studies include magnetic resonance imaging (MRI), X-ray computed tomography (CT) and in the case of 'bone scans' nuclear medicine. However, a nuclear bone scan is a functional test, which means it measures an aspect of bone metabolism, which most other imaging techniques cannot. The nuclear bone scan competes with the FDG-PET scan in seeing abnormal metabolism in bones, but it is considerably less expensive.

Nuclear bone scans are not to be confused with the completely different test often termed a "bone density scan," DEXA or DXA, which is a low exposure X-ray test measuring bone density to look for osteoporosis and other diseases where bones lose mass, without any bone re-building activity. The nuclear medicine scan technique is sensitive to areas of unusual bone re-building activity because the radiopharmaceutical is taken up by osteoblast cells which build bone. The technique therefore is sensitive to fractures and bone reaction to infections and bone tumors, including tumor metastases to bones, because all these pathologies trigger bone osteoblast activity. The bone scan is not sensitive to osteoporosis or multiple myeloma in bones, and therefore other techniques must be used to assess bone abnormalities from these diseases.

Pathophysiology of Parkinson's Disease
Pathophysiology of Parkinson's Disease samer kareem 1,450 Views • 3 years ago

Parkinson disease (PD) is a common neurodegenerative condition. Typically beginning in the sixth or seventh decade of life, it is characterized by the unilateral onset of resting tremor in combination with varying degrees of rigidity and bradykinesia. PD was originally described by James Parkinson (1755-1824), a man of many talents and interests. Parkinson published works on chemistry, paleontology, and other diverse topics. Early in his career he was a social activist championing the rights of the disenfranchised and poor. His efforts in this area were enough to result in his arrest and appearance before the Privy Council in London on at least one occasion. In collaboration with his son, who was a surgeon, he also offered the first description in the English language of a ruptured appendix. His small but famous publication, "Essay on the Shaking Palsy," was published in 1817, seven years before his death. The clinical descriptions of 6 cases was remarkable in part because he never actually examined the people he described. Instead, he had simply observed these people on the streets of London.
