Toxoplasmosis: samer kareem 7,105 vistas • 3 años hace

Toxoplasmosis (tok-so-plaz-MOE-sis) is a disease that results from infection with the Toxoplasma gondii parasite, one of the world's most common parasites. Toxoplasmosis may cause flu-like symptoms in some people, but most people affected never develop signs and symptoms. For infants born to infected mothers and for people with weakened immune systems, toxoplasmosis can cause extremely serious complications. If you're generally healthy, you probably won't need any treatment for toxoplasmosis. If you are pregnant or have lowered immunity, certain medications can help reduce the infection's severity. The best approach, though, is prevention.

Microsurgical bipolar cautery tonsillectomy compares favorably with traditional techniques in terms of intraoperative bleeding, postoperative pain, otalgia, and hemorrhage. This technique combines the hemostatic advantage of cautery dissection, the excellent visualization achieved by a microscope, and, with the use of a video, greatly improves the physician's ability to teach how to perform a tonsillectomy.

Sialorrhea Injection Site Identification
Sialorrhea Injection Site Identification samer kareem 7,086 vistas • 3 años hace

Sialorrhea or excessive drooling is a major issue in children with cerebral palsy and adults with neurodegenerative disorders. In this review, we describe the clinical features, anatomy and physiology of sialorrhea, as well as a review of the world literature on medical treatment using Yale University’s search engine; including but not limited to Medline and Erasmus. Level of drug efficacy is defined according to the guidelines of American Academy of Neurology. Current medical management is unsatisfactory. Topical agents (scopolamine and tropicamide) and oral agents (glyccopyrolate) combined render a level B evidence (probably effective); however, this treatment is associated with troublesome side effects. Double-blind and placebo-controlled studies of botulinum toxin (BoNT) provide a level A evidence for type B (two class I studies; effective and established) and both overall and individual B level of evidence for OnabotulinumtoxinA (A/Ona) and AbobotulinumtoxinA (A/Abo); these are probably effective. For IncobotulinumtoxinA (A/Inco), the level of evidence is U (insufficient) due to lack of blinded studies. Side effects are uncommon; transient and comparable between the two types of toxin. A clinical note at the end of this review comments on fine clinical points. Administration of BoNTs into salivary glands is currently the most effective way of treating sialorrhea.

Complex cataract and glaucoma surgery
Complex cataract and glaucoma surgery Scott 7,076 vistas • 3 años hace

Phacolytic glaucoma usually is associated with a mature or hypermature cataract and typically occurs in elderly patients. Today, phacolytic glaucoma is rare in the United States, found primarily in areas where access to care is poor. Will the increase in the number of under- and uninsured patients lead to an increase in this condition? Evaluation and Diagnosis Signs and symptoms. Patients typically report acute-onset pain, decreased vision, tearing and photophobia. Examination will reveal injection, corneal edema, elevated IOP, anterior chamber reaction with or without pseudohypopyon, particles on the lens capsule and anterior capsule wrinkling. Patient history. The duration of symptoms should be elicited; a delayed presentation of more than five days since onset can result in glaucomatous disc damage and poorer prognosis.¹ The ocular history may reveal that the patient decided against removal of an advanced cataract. Prior intraocular surgery or trauma may have left residual lens material that could cause phacoanaphylactic glaucoma or exacerbate infectious endophthalmitis. Visual acuity and visual potential should be assessed. Exam essentials. A complete ophthalmologic examination should be done. The eye should be inflamed, and the cornea may be edematous due to the high IOP. The anterior chamber will demonstrate massive inflammation and/ or pseudohypopyon. Gonioscopy is essential; it will help rule out angle closure due to phacomorphic glaucoma or neovascularization of the angle. Assess ment of the posterior pole should be performed to rule out vitreous hemorrhage (which can result in ghost-cell glaucoma) or vitritis (which may be associated with infectious endophthalmitis or panuveitis). If the view to the fundus is obstructed, B-scan ultrasonography also should be performed. Differential diagnosis. The differential diagnosis includes infectious endophthalmitis, phacoanaphylactic glaucoma, inflammatory glaucoma, glaucoma secondary to intraocular tumor, phacomorphic glaucoma, acute-angle closure glaucoma and neovascular glaucoma. Management Medication. Medical management is used to temporarily control the glaucoma and inflammation. Initial treatment consists of hyperosmotic agents, aqueous suppressants, anti-inflammatory drugs and cycloplegics. Surgery. Definitive treatment is removal of the lens via extracapsular cataract extraction with or without an IOL. Some ophthalmologists defer placement of an IOL until after the inflammation subsides; however, there is no significant difference in final visual acuity between those patients who did receive an IOL and those who did not.¹ If the phacolytic glaucoma is of long duration (more than seven days), a combined trabeculectomy may be needed to prevent postoperative IOP spikes.² In eyes with hypermature Morgagnian cataracts, one must be especially careful, as the capsule is fragile, the zonules are weak and the view is difficult due to the white, milky cortex. Vision limited to light perception on presentation is not a contraindication to performing cataract extraction. Surgical Tips For a planned extracapsular cataract extraction with a posterior chamber IOL, fashion a superior fornix-based conjunctival flap.³ Make a partial-thickness incision along the sclerolimbal junction superiorly for 120 degrees with a No. 69 blade. Forty-five degrees away, a paracentesis should be done to decompress the eye. The anterior chamber fluid can be withdrawn for analysis, to look for macrophages and high molecular-weight proteins. Inject balanced salt solution in a cannula to wash out any residual particulate matter, then inject Healon or viscoelastic into the anterior chamber. Make an incision entering the anterior chamber at the 12 o’clock position with a keratome. A 26-gauge cystotome mounted on a syringe is then introduced through the 12 o’clock incision and used to puncture the capsular bag. The milky cortex should be aspirated as much as possible, until the nucleus is visible. Withdraw the needle through the keratome incision, then inject Healon through the 12 o’clock incision into the capsular bag. Next, enlarge the corneoscleral keratome incision with curved Westcott scissors to 120 degrees. Perform a partial V-shaped capsulotomy; this can be done either with the cystotome or with an angled Vannas scissors. Place viscoelastic under the nucleus to float the nucleus and sever any adhesions between the nucleus and the capsule. The nuclear portion of the lens can then be removed with an irrigating vectis (lens loop) with or without gentle pressure at the inferior limbus (6 o’clock). Irrigate and aspirate the residual cortex with the Simcoe cannula. Inspect the capsular bag; if it is intact, place a posterior chamber IOL into the bag. Close the incision with several interrupted 10-0 monofilament nylon sutures and reattach the conjunctival flap. Potential Sequelae and Prognosis Postoperatively, the patient should be managed with topical steroids and/or aqueous suppressants and hyperosmotics if necessary. Vitreous opacification behind the posterior capsule occurs in a small percentage of eyes. These vitreous opacities are typically absorbed by one to two weeks postoperatively. IOP usually is controlled without antiglaucoma medications after the cataract removal. A detailed glaucoma evaluation (including repeat gonioscopy to assess for peripheral anterior synechiae, visual field and optic nerve status) should be done to assess the extent of glaucomatous damage. The prognosis is dependent on the duration of elevated IOP, PAS and optic nerve damage. In one study, patients who were older than 60 and whose glaucoma was present for more than five days did significantly worse than a comparison group of younger individuals with shorter disease duration.

Breast Abscess Drainage
Breast Abscess Drainage samer kareem 7,044 vistas • 3 años hace

Breast abscesses are often linked to mastitis – a condition that causes breast pain and swelling (inflammation), and usually affects women who are breastfeeding. Infections can occur during breastfeeding if bacteria enter your breast tissue, or if the milk ducts (tiny tubes) become blocked. This can cause mastitis which, if not treated, can result in an abscess forming. Women who aren't breastfeeding can also develop mastitis if bacteria enter the milk ducts through a sore or cracked nipple, or a nipple piercing. White blood cells are sent to attack the infection, which causes tissue at the site of the infection to die. This creates a small, hollow area that fills with pus (an abscess).
