Debridement is the removal of necrotic tissue, foreign debris, bacterial growth, callus, wound edge, and wound bed tissue from chronic wounds in order to stimulate the wound healing process. Stimulation of wound healing mediated by debridement is thought to occur by the conversion of a chronic non-healing wound environment to an acute healing environment through the removal of cells that are not responsive to endogenous healing stimuli. Debridement is used commonly in standard wound treatment of diabetic foot ulcers (DFUs). Methods of debridement include surgery (sharp debridement), chemical debridement (antiseptics, polysaccharide beads, pastes), autolytic (hydrogels, hydrocolloids and transparent films), biosurgery (maggots), mechanical (hydrodebridement), and biochemical debridement (enzyme preparations). Callus is a buildup of keratinized skin formed under conditions of repeated pressure or friction and may contribute to ulcer formation by creating focal areas of high plantar pressure. The debridement of callus has been proposed to be relevant for both treatment and prevention of DFU. The purpose of this report is to retrieve and review existing evidence of comparative clinical effectiveness of different methods of debridement for the treatment of DFUs. Additionally examined in this report is the clinical effectiveness for treatment and prevention of DFU using callus debridement. Cost-effectiveness, and existing debridement guidelines for the treatment of DFUs will also be reviewed.

Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle.

A diaphragm is a shallow, bendable cup that you put inside your vagina. It covers your cervix during sex to prevent pregnancy.

Symptoms of blood clots in specific body locations are as follows: Symptoms of blood clots in legs (deep vein thrombosis (DVT) are pain, redness, and swelling. Symptoms of an arterial blood clot in a limb (leg or arm) include pain, pale color, and coolness to the touch. and the leg is cool and pale.

An amputation is the removal of an extremity or appendage from the body. Amputations in the upper extremity can occur as a result of trauma, or they can be performed in the treatment of congenital or acquired conditions. Although successful replantation represents a technical triumph to the surgeon, the patient's best interests should direct the treatment of amputations. The goals involved in the treatment of amputations of the upper extremity include the following : Preservation of functional length Durable coverage Preservation of useful sensibility Prevention of symptomatic neuromas Prevention of adjacent joint contractures Early return to work Early prosthetic fitting These goals apply differently to different levels of amputation. Treatment of amputations can be challenging and rewarding. It is imperative that the surgeon treat the patient with the ultimate goal of optimizing function and rehabilitation and not become absorbed in the enthusiasm of the technical challenge of the replantation, which could result in poorer outcome and greater financial cost due to lost wages, hospitalization, and therapy.

Epididymitis is infection or less frequently, inflammation of the epididymis (the coiled tube on the back of the testicle). The majority of men that develop epididymitis develop it because of a bacterial infection. Although males of any age can develop epididymitis, it occurs most frequently between ages of 20 to 39.

Knee replacement, commonly known as complete knee replacement or knee arthroplasty, is a surgical treatment that resurfaces a knee that has been destroyed by arthritis. The extremities of the bones that make up the knee joint, as well as the kneecap, are capped with metal and plastic pieces. Someone with severe arthritis or a major knee injury may benefit from this procedure.

The knee joint can be affected by a variety of arthritis forms. The degradation of joint cartilage and neighboring bone in the knees can be caused by osteoarthritis, a degenerative joint disease that primarily affects middle-aged and older persons. Rheumatoid arthritis produces pain and stiffness by inflaming the synovial membrane and resulting in an excess of synovial fluid. Traumatic arthritis, or arthritis caused by an injury, can harm the joints.
The purpose of knee replacement surgery is to resurface damaged areas of the knee joint and cure knee discomfort that has not responded to prior therapies.

Your temporomandibular joint is a hinge that connects your jaw to the temporal bones of your skull, which are in front of each ear. It lets you move your jaw up and down and side to side, so you can talk, chew, and yawn. Problems with your jaw and the muscles in your face that control it are known as temporomandibular disorders (TMD). But you may hear it wrongly called TMJ, after the joint.

Ca2+ binds with the membrane of the synaptic vesicles, which causes the vesicles to break and release the neurotransmitter into the synaptic cleft. After the neurotransmitters are released, they diffuse across the synaptic cleft and interact with receptors on the postsynaptic membrane. When the action potential reaches the presynaptic terminal, it provokes the release of a small quantity of neurotransmitter molecules, which bind to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft.

Respiratory syncytial virus (RSV) is a virus that causes infections of the lungs and respiratory tract. It's so common that most children have been infected with the virus by age 2. Respiratory syncytial (sin-SISH-ul) virus can also infect adults. In adults and older, healthy children, the symptoms of respiratory syncytial virus are mild and typically mimic the common cold. Self-care measures are usually all that's needed to relieve any discomfort. Infection with respiratory syncytial virus can be severe in some cases, especially in premature babies and infants with underlying health conditions. RSV can also become serious in older adults, adults with heart and lung diseases, or anyone with a very weak immune system (immunocompromised).

Elbow Exam - Orthopaedic OSCE - Clinical Skills - Dr Gill

The elbow examination is a core skill - in this video, we demonstrate how to perform an elbow EXAM for an Orthopaedic Clinical Skills OSCE, which should be one of the more accessible examination stations for medical students.

For a passing grade in your Clinical Skills OSCE, an elbow assessment should follow the LOOK, FEEL, MOVE approach

Initially looking for erythema, scars, swelling and position

Palpating the elbow - specifically the olecranon, medial and lateral epicondyles, and radial head for heat, oedema and crepitus

Finally assess range of movement with flexion and extension at the elbow, before determining for tennis and golfers' elbows

------------

Please note that there is no ABSOLUTE way to perform a clinical examination. Different institutions and even clinicians will have differing degrees of variations - the aim is the effectively identify medically relevant signs.

However during OSCE assessments. Different medical schools, nursing colleges and other health professional courses will have their own preferred approach to a clinical assessment - you should concentrate on THEIR marks schemes for your assessments.

The examination demonstrated here is derived from Macleods Clinical Examination - a recognised standard textbook for clinical skills.
