Trabeculectomy, also called Filtration Surgery, is a surgical procedure performed for treatment of glaucoma. The treatment involves removing part of the trabecular meshwork and creating a new escape route for the aqueous humor. When successful, it allows the aqueous fluid to drain from the eye into an area underneath the conjunctiva where it is subsequently absorbed by the body's circulatory system or filtered into tears.
In this procedure:
- A conjunctival pocket is created and maybe treated with Mitomycin or other antimetabolites for a few minutes. These drugs are used to prevent scarring of the operation site. Scarring, if occurs, may clog the new drainage canal, and is therefore the major reason the procedure may fail.
- A half thickness flap is then made in the sclera and is dissected all the way to the clear cornea.
- A block of scleral tissue including part of the trabecular meshwork and Schlemm's canal is then removed to make a hole into the anterior chamber of the eye.
- As the iris may plug up this hole from the inside, a piece of the iris maybe removed at this time. This is called iridectomy.
- The scleral flap is then sutured loosely back in place. These sutures can be released gradually during a couple of weeks after surgery. This allows adjustment of the aqueous flow in order to achieve target pressure and to avoid the complication of having a too low intraocular pressure.
- The conjunctiva is sewn back in place to cover the area.
After surgery, aqueous humor drains into a filtering area called a "bleb" under the conjunctiva. Since the surgery is usually performed near the top of the eye, the bleb can easily be concealed behind the upper eyelid.

Thyroid Problems For Women
Thyroid Problems For Women samer kareem 4,418 Views • 2 years ago

Through the hormones it produces, the thyroid gland influences almost all of the metabolic processes in your body. Thyroid disorders can range from a small, harmless goiter (enlarged gland) that needs no treatment to life-threatening cancer. The most common thyroid problems involve abnormal production of thyroid hormones. Too much thyroid hormone results in a condition known as hyperthyroidism. Insufficient hormone production leads to hypothyroidism. Although the effects can be unpleasant or uncomfortable, most thyroid problems can be managed well if properly diagnosed and treated.

A lumbar puncture (also called a spinal tap) is a procedure to collect and look at the fluid (cerebrospinal fluid, or CSF) surrounding the brain and spinal cord. During a lumbar puncture, a needle is carefully inserted into the spinal canal low in the back (lumbar area). Samples of CSF are collected.

Neuropathic pain: palmitoylethanolamide, natural painkiller jan keppel hesselink 2,207 Views • 2 years ago

Neuropathic pain: often difficult to treat. Palmitoylethanolamide (PEA) is a very special molecule, produced in our own body, against pain and chronic inflammation. PEA is available as supplement and as cream, and as dietfood for medical purposes in Italy and Spain. It has been explored since 1957 and has a clear analgesic and anti-inflammatory efficacy, and virtually no side effects. Meanwhile within the context of clinical trials 5000 patients have been using PEA, and its efficacy and safety has been documented in more than 400 scientific papers: http://palmitoylethanolamide4pain.com/about-2/ a website containing 400+ scientific articles on PEA in 6 different languages.

Beta-blockers, also known as beta antagonists, beta-adrenergic blocking agents, or beta-adrenergic antagonists, are drugs that are prescribed to treat several different types of conditions, including hypertension (high blood pressure), angina, some abnormal heart rhythms, heart attack (myocardial infarction), anxiety, migraine, glaucoma, and overactive thyroid symptoms.

Patent ductus arteriosus (PDA), in which there is a persistent communication between the descending thoracic aorta and the pulmonary artery that results from failure of normal physiologic closure of the fetal ductus (see image below), is one of the more common congenital heart defects.

Any independent vertical movement of the transducer or the patient will affect the hydrostatic column of this fluid-filled system and thus alter the pressure measurements. At some time before or after PAC insertion, the system must therefore be zeroed to ambient air pressure. The reference point for this is the midpoint of the left atrium (LA), estimated as the fourth intercostal space in the midaxillary line with the patient in the supine position. With the transducer at this height, the membrane is exposed to atmospheric pressure, and the monitor is then adjusted to zero. Calibration Once zeroed, the monitoring system must be calibrated for accuracy. Currently, most monitors perform an automated electronic calibration. Two methods are used to manually calibrate and check the system. If the catheter has not been inserted, the distal tip of the PAC is raised to a specified height above the LA. For example, raising the tip 20 cm above the LA should produce a reading of approximately 15 mm Hg if the system is working properly (1 mm Hg equals 1.36 cm H 2 O). Alternatively, pressure can be applied externally to the transducer and adjusted to a known level using a mercury or aneroid manometer. The monitor then is adjusted to read this pressure, and the system is calibrated. Dynamic tuning Central pressures are dynamic waveforms (ie, they vary from systole to diastole) and thus have a periodic frequency. To monitor these pressures accurately, the system requires an appropriate frequency response. A poorly responsive system produces inaccurate pressure readings, and differentiating waveforms (eg, PA from pulmonary capillary wedge pressure [PCWP]) can become difficult. When signal energy is lost, the pressure waveform is dampened. Common causes of this are air bubbles (which are compressible), long or compliant tubing, vessel wall impingement, intracatheter debris, transducer malfunction, and loose connections in the tubing. A qualitative test of the frequency response is performed by flicking the catheter and observing a brisk high-frequency response in the waveform. After insertion, the system can be checked by using the rapid flush test. When flushed, an appropriately responsive system shows an initial horizontal straight line with a high-pressure reading. Once the flushing is terminated, the pressure drops immediately, which is represented by a vertical line that plunges below the baseline. A brief and well-defined oscillation occurs, followed by return of the PA waveform. A dampened system will not overshoot or oscillate, and causes a delay in returning to the PA waveform.

INDICATIONS The Absorb GT1 Bioresorbable Vascular Scaffold (BVS) is a temporary scaffold that will fully resorb over time and is indicated for improving coronary luminal diameter in patients with ischemic heart disease due to de novo native coronary artery lesions (length ≤ 24 mm) with a reference vessel diameter of ≥ 2.5 mm and ≤ 3.75 mm WHAT ARE THE POTENTIAL RISKS AND COMPLICATIONS? Treatment options for CAD have become increasingly common but, as with any invasive procedure, there are potential risk factors and complications. Serious complications do not occur often, and research is ongoing to make these procedures even safer and more effective. The risk of complications from percutaneous treatment methods may be higher for individuals: 75 years of age and older Who are women Who have kidney disease or diabetes Who have serious heart disease Who have had prior cardiac interventions

Pulmonary edema, lungs
Pulmonary edema, lungs samer kareem 7,663 Views • 2 years ago

Expand Section. Pulmonary edema is often caused by congestive heart failure. When the heart is not able to pump efficiently, blood can back up into the veins that take blood through the lungs. As the pressure in these blood vessels increases, fluid is pushed into the air spaces (alveoli) in the lungs.
