Complex cataract and glaucoma surgery
Complex cataract and glaucoma surgery Scott 7,048 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.

Laryngectomy

Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy the entire larynx is removed and in a partial laryngectomy only a portion is taken out. The laryngectomee breathes through an opening in the neck known as a stoma.

Robotic Partial Nephrectomy
Robotic Partial Nephrectomy samer kareem 2,311 Views • 2 years ago

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

Neonatal Resuscitation
Neonatal Resuscitation samer kareem 28,055 Views • 2 years ago

The following guidelines are an interpretation of the evidence presented in the 2010 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations1). They apply primarily to newly born infants undergoing transition from intrauterine to extrauterine life, but the recommendations are also applicable to neonates who have completed perinatal transition and require resuscitation during the first few weeks to months following birth. Practitioners who resuscitate infants at birth or at any time during the initial hospital admission should consider following these guidelines. For the purposes of these guidelines, the terms newborn and neonate are intended to apply to any infant during the initial hospitalization. The term newly born is intended to apply specifically to an infant at the time of birth.

Digoxin is derived from the leaves of a digitalis plant. Digoxin helps make the heart beat stronger and with a more regular rhythm. Digoxin is also used to treat atrial fibrillation, a heart rhythm disorder of the atria (the upper chambers of the heart that allow blood to flow into the heart).

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,346 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

Liddle's Syndrome samer kareem 1,864 Views • 2 years ago

Liddle syndrome is an inherited form of high blood pressure (hypertension). This condition is characterized by severe hypertension that begins unusually early in life, often in childhood, although some affected individuals are not diagnosed until adulthood. Some people with Liddle syndrome have no additional signs or symptoms, especially in childhood. Over time, however, untreated hypertension can lead to heart disease or stroke, which may be fatal.

Cellulite betrifft mehr als 90% der Frauen nach der Pubertät. Wir finden unterschiedlichen Cellulite Graden und die häufigste ist als Orangenhaut bekannt. Wir verwenden den Begriff “Cellulite”, um die Fettablagerungen unter der Haut zu beschreiben. Diese Fett verursacht die Grübchen der Hüften, Oberschenkel, Gesäß und Bauch. Diese Bedingung betrifft fast ausschließlich Frauen und tritt selten bei Männern. Im Gegensatz zu dem verbreiteten Glaube, Cellulite hat nichts mit Übergewicht zu tun. Cellulite wird in beiden übergewichte und dünne Menschen gefunden. Der Markt bietet verschiedene Möglichkeiten, um Cellulite zu bekämpfen, aber in den meisten Fällen sind diese Methoden nicht wirksam. Sowohl Cremen als auch Massage oder andere Art von Cellulite Entfernung geben keine befriedigenden Ergebnisse. Es gibt verschiedene Faktoren, die Cellulite verursachen. Einer der wichtigsten ist die hormonelle Faktor. Die hormonelle Veränderungen während der Pubertät, Schwangerschaft, Wechseljahre oder wenn Sie mit Antibabypillen beginnen. Die Hormone regulieren die Veränderungen im Blutfluss, Lymphdrainage, Fett-und Bindegewebe, die die Bildung von Cellulite verursachen. Mangel an Bewegung ist auch eine sehr wichtige Ursache. Der Bewegungsmangel verursacht nicht nur das Erscheinungsbild der Cellulite, sondern auch verschlechtert ihr Aussehen im Laufe der Zeit.

Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

An arthroscopic meniscectomy is a procedure to remove some or all of a meniscus from the tibio-femoral joint of the knee using arthroscopic (aka 'keyhole') surgery. In a complete meniscectomy the meniscus including the meniscal rim is removed. A partial meniscectomy involves partial removal of the meniscus. This may vary from minor trimming of a frayed edge to anything short of removing the rim. This is a minimally invasive procedure often done as day suas an outpatient in a one-day clinic [1] This procedure is performed when a meniscal tear is too large to be corrected by a surgical meniscal repair.[1] When non-operative therapy provides some degree of symptom relief over the long-term, these benefits may wane with continued meniscal degeneration. In such patients, arthroscopic partial meniscectomy can be effective in improving patient quality of life.

Tummy Tuck Surgery
Tummy Tuck Surgery Scott 3,610 Views • 2 years ago

Tummy tuck surgery, also known as abdominoplasty, removes excess fat and skin and, in most cases, restores weakened or separated muscles creating an abdominal profile that is smoother and firmer. A flat and well-toned abdomen is something many of us strive for through exercise and weight control. Sometimes these methods cannot achieve our goals. Even individuals of otherwise normal body weight and proportion can develop an abdomen that protrudes or is loose and sagging. The most common causes of this include: Aging Heredity Pregnancy Prior surgery Significant fluctuations in weight What tummy tuck surgery can't do A tummy tuck is not a substitute for weight loss or an appropriate exercise program. Although the results of a tummy tuck are technically permanent, the positive outcome can be greatly diminished by significant fluctuations in your weight. For this reason, individuals who are planning substantial weight loss or women who may be considering future pregnancies would be advised to postpone a tummy tuck. A tummy tuck cannot correct stretch marks, although these may be removed or somewhat improved if they are located on the areas of excess skin that will be excised.
