The first step is to see if you have pigmentation issues -not really classed as acne scars, but this is controversial, or if you have contour changes. The best thing to do is to examine under tangential or angled lighting, as this will reveal all. Once this is done, scars can be subtyped and mapped, with high resolution photos. The second aspect, which is equally as important is to examine scars upon animanation, namely when you speak, smile and move your face. This will give me an idea of the amount of tethering and anchored acne scars. Time and time again I get request for ‘what is the treatment’ with static photos, an impossible task to answer correctly. Acne scar assessment has to be done live- with the patient in front of you, and lighting from all angles. Photos do not map scars as well a real time examination under magnification and lighting.

The venipuncture procedure is complex, requiring both knowledge and skill to perform. Each phlebotomist generally establishes a routine that is comfortable for her or him. Several essential steps are required for every successful collection procedure: Identify the patient. Assess the patient's physical disposition (i.e. diet, exercise, stress, basal state). Check the requisition form for requested tests, patient information, and any special requirements. Select a suitable site for venipuncture. Prepare the equipment, the patient and the puncture site. Perform the venipuncture. Collect the sample in the appropriate container. Recognize complications associated with the phlebotomy procedure. Assess the need for sample recollection and/or rejection. Label the collection tubes at the bedside or drawing area. Promptly send the specimens with the requisition to the laboratory.

Rotator cuff repair is surgery to repair a torn tendon in the shoulder. The procedure can be done with a large (open) incision or with shoulder arthroscopy, which uses small buttonhole-sized incisions.

A subdural hematoma (SDH) is a collection of blood below the inner layer of the dura but external to the brain and arachnoid membrane (see the images below). Subdural hematoma is the most common type of traumatic intracranial mass lesion. Subdural hematoma occurs not only in patients with severe head injury but also in patients with less severe head injuries, particularly those who are elderly or who are receiving anticoagulants. Subdural hematoma may also be spontaneous or caused by a procedure, such as a lumbar puncture (see Etiology). Rates of mortality and morbidity can be high, even with the best medical and neurosurgical care (see Prognosis). Subdural hematomas are usually characterized on the basis of their size and location and the amount of time elapsed since the inciting event age (ie, whether they are acute, subacute, or chronic). When the inciting event is unknown, the appearance of the hematoma on neuroimaging studies can help determine when the hematoma occurred. These factors, as well as the neurologic and medical condition of the patient, determine the course of treatment and may also influence the outcome. Generally, acute subdural hematomas are less than 72 hours old and are hyperdense compared with the brain on computed tomography scans. The subacute phase begins 3-7 days after acute injury. Chronic subdural hematomas develop over the course of weeks and are hypodense compared with the brain. However, subdural hematomas may be mixed in nature, such as when acute bleeding has occurred into a chronic subdural hematoma. Presentation varies widely in acute subdural hematoma (see Clinical). Many of these patients are comatose on admission. However, approximately 50% of patients with head injuries who require emergency neurosurgery present with head injuries that are classified as moderate or mild (Glasgow Coma Scale scores 9-13 and 14-15, respectively). Many of these patients harbor intracranial mass lesions. In a large series of patients who developed intracranial hematomas requiring emergent decompression, more than half had lucid intervals and were able to make conversation between the time of their injury and subsequent deterioration. In a more comprehensive review of the literature on the surgical treatment of acute subdural hematomas, lucid intervals were noted in up to 38% of cases. These patients may be more likely to benefit from medical and surgical intervention when instituted in a timely fashion (ie, before further neurological deterioration).

One of a series of films we produced to help patients, their families and carers learn more about some of the most common tests and procedures used to diagnose and treat blood diseases. Patients who have previously undergone these tests helped us to design the videos. Each film clearly explains what the procedure involves and addresses common issues and concerns including: Why your doctor recommended this procedure What you need to do to prepare What you can expect during the procedure What you need to do afterwards Not every patient will be referred for all of these tests and practice may differ slightly depending on where you are treated.

rostbite refers to the freezing of body tissue (usually skin) that results when the blood vessels contract, reducing blood flow and oxygen to the affected body parts. Normal sensation is lost, and color changes also occur in these tissues.

Toxic shock syndrome is a rare, life-threatening complication of certain types of bacterial infections. Often toxic shock syndrome results from toxins produced by Staphylococcus aureus (staph) bacteria, but the condition may also be caused by toxins produced by group A streptococcus (strep) bacteria. Toxic shock syndrome historically has been associated primarily with the use of superabsorbent tampons. However, since manufacturers pulled certain types of tampons off the market, the incidence of toxic shock syndrome in menstruating women has declined. Toxic shock syndrome can affect men, children and postmenopausal women. Risk factors for toxic shock syndrome include skin wounds and surgery.

Eosinophilic granulomatosis with polyangiitis (EGPA)—or, as it was traditionally termed, Churg-Strauss syndrome—is a rare systemic necrotizing vasculitis that affects small-to-medium-sized vessels and is associated with severe asthma and blood and tissue eosinophilia. [1] Like granulomatosis with polyangiitis (Wegener granulomatosis), and the microscopic form of periarteritis (ie, microscopic polyangiitis), EGPA is an antineutrophil cytoplasmic antibody (ANCA)–associated vasculitide. [2, 3, 4, 5] In 1951, Churg and Strauss first described the syndrome in 13 patients who had asthma, eosinophilia, granulomatous inflammation, necrotizing systemic vasculitis, and necrotizing glomerulonephritis. [3] In 1990, the American College of Rheumatology (ACR) proposed the following six criteria for the diagnosis of Churg-Strauss syndrome [6] : Asthma (wheezing, expiratory rhonchi) Eosinophilia of more than 10% in peripheral blood Paranasal sinusitis Pulmonary infiltrates (may be transient) Histological proof of vasculitis with extravascular eosinophils Mononeuritis multiplex or polyneuropathy

Patients with candida endophthalmitis who have chorioretinitis with vitreal involvement should be treated with vitrectomy and systemic antifungal therapy with amphotericin B (Choice B) and/or fluconazole. An early vitrectomy improves the likelihood of a positive outcome, and intravitreal injection of amphotericin B may be of help. Prompt diagnosis and treatment of candida endophthalmitis is essential, as the condition can worsen quickly.
