PCP (Phencyclidine)
PCP (Phencyclidine) samer kareem 3,561 Views • 2 years ago

Phencyclidine (PCP) was developed in the 1950s as an intravenous anesthetic but, due to the side effects of confusion and delirium, its development for human medical use was discontinued. In its pure form, it is a white crystalline powder that readily dissolves in water or alcohol and has a distinctive bitter chemical taste. On the illicit drug market, Phencyclidine contains a number of contaminants as a result of makeshift manufacturing, causing the color to range from tan to brown, and the consistency to range from powder to a gummy mass. It is available in a variety of tablets, capsules, and colored powders, which are either taken orally or snorted. The liquid form of phencyclidine is actually phencyclidine base dissolved most often in ether, a highly flammable solvent. For smoking, phencyclidine is typically sprayed onto leafy material such as mint, parsley, oregano, or marijuana.

There is nothing that compares to the fresh-faced feeling you have when you leave the aesthetician after a facial. There is just something so freeing about knowing that nasty little buggers like blackheads, whiteheads and all other kinds of heads have been given the heave-ho. That could be why this Facebook video of a blackhead being removed has gone viral. With more than 24 million views, the popular video is weirdly difficult to stop watching.

Complex cataract and glaucoma surgery
Complex cataract and glaucoma surgery Scott 7,046 Views • 2 years ago

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.

Sinusitis
Sinusitis samer kareem 14,526 Views • 2 years ago

Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain. There are several types of sinusitis, including Acute, which lasts up to 4 weeks Subacute, which lasts 4 to 12 weeks Chronic, which lasts more than 12 weeks and can continue for months or even years Recurrent, with several attacks within a year Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis. Symptoms of sinusitis can include fever, weakness, fatigue, cough, and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip. Your health care professional diagnoses sinusitis based on your symptoms and an examination of your nose and face. You may also need imaging tests. Treatments include antibiotics, decongestants, and pain relievers. Using heat pads on the inflamed area, saline nasal sprays, and vaporizers can also help.

Anti Rides Efficace, Comment Faire Un Régime Pour Mincir Vite, Aliment Brûle Graisse, Poids Graisse ---- http://rajeunir-de-10-ans.info-pro.co --- 5 Raisons pour lesquelles le Cardio traditionnel n’est PAS bon pour vous. Voici le problème : si vous cherchez à rentabiliser au maximum le temps que vous passez à vous entrainer, le cardio de longue durée à faible intensité n'est pas la voie à suivre… et pour de nombreuses raisons. Voici le top 5 de ces raisons : 1. Un nombre réduit de calories brûlées : 45 minutes sur un tapis de course peut vous aider à brûler au maximum 300 calories si vous êtes chanceux, l'équivalent de 50 grammes de graisse. En faisant dix heures de tapis de course par semaine vous pourriez perdre un demi-kilo ! 2. Beaucoup trop de temps consacré : je ne sais pas pour vous, mais je n'ai pas des heures et des heures de mon temps à mettre dans l’entraînement chaque semaine. En fait, j'ai seulement le temps de faire quelques heures d'exercice par semaine, et vous savez quoi ? C'est tout ce dont vous avez besoin. En fait, la recherche a montré que plus de 90 minutes par semaine peuvent être nuisibles! Au-delà de cela, le cardio de longue durée et faible intensité est : 3. Ennuyeux à mourir : assis sur un vélo d'exercice à regarder le mur en face de moi pendant 45-60 minutes ? Non merci. Mais peut-être pire encore est le fait que le cardio de longue durée et à faible intensité ne fournit : Pas d’avantages prolongés au niveau métabolique : saviez-vous qu’avec de l'exercice avec plus d'intensité il est possible de continuer à brûler des calories pour un maximum de 48 heures après l'entraînement ? C'est vrai. Mais vous savez ce qui est vrai également ? Le cardio de longue durée et à faible intensité ne fournit pratiquement aucune stimulation prolongée du métabolisme. En fait, avec un cardio lent et à faible intensité, le métabolisme revient à la normale presque immédiatement après la séance d'exercice. Et enfin, la raison qui l'emporte sur toutes les autres : 5. Une perte de graisse minimale : un minimum de calories sont brûlées pendant la session et pratiquement aucunes calories supplémentaires ne sont brûlées après… donc aucune perte de graisse supplémentaire. Et soyons honnêtes, la seule raison pour laquelle quelqu'un fait du cardio c'est pour avoir des "résultats visibles". Donc, si le cardio de longue durée à faible intensité n'est pas la solution idéale, quelle est-elle ? ET bien les solutions sont multiples et vous n'avez pas besoin de passer des heures et des heures chaque semaine à vous entrainer de façon stupide pour obtenir les meilleures résultats possibles.

Signs and symptoms of bone cancer
Signs and symptoms of bone cancer samer kareem 1,648 Views • 2 years ago

Pain in the affected bone is the most common complaint of patients with bone cancer. At first, the pain is not constant. It may be worse at night or when the bone is used (for example, leg pain when walking). As the cancer grows, the pain will be there all the time. The pain increases with activity and the person might limp if a leg is involved.

Blood Transfusion
Blood Transfusion samer kareem 1,613 Views • 2 years ago

A blood transfusion is a routine medical procedure that can be lifesaving. During a blood transfusion, donated blood is added to your own blood. A blood transfusion may also be done to supplement various components of your blood with donated blood products. In some cases, a blood transfusion is done with blood that you've donated ahead of time before you undergo elective surgery. During a typical blood transfusion, certain parts of blood are delivered through an intravenous (IV) line that's placed in one of the veins in your arm. A blood transfusion usually takes one to four hours, though in an emergency it can be done much faster.
