Portal hypertension is an increase in the blood pressure within a system of veins called the portal venous system. Veins coming from the stomach, intestine, spleen, and pancreas merge into the portal vein, which then branches into smaller vessels and travels through the liver.
-Korsakoff's syndrome is a common and preventable sequel of Wernicke's encephalopathy. Thiamine, if given during the stage of Wernicke's encephalopathy, can prevent the onset of Korsakoff's psychosis. The administration of glucose prior to thiamine can precipitate Korsakoff's syndrome, as seen in this case. In such patients, brain MRI frequently shows abnormal enhancement of the mammillary bodies & thallamus

Aim: To detail two different clinical protocols and case studies using mini-implant anchorage developed to respond to certain clinical conditions. Methods: Two clinical protocols are described to upright mesially tilted mandibular molars. In the first protocol, a single mini-implant is inserted distally to the molar to be uprighted, and an elastic traction chain is applied to the tooth. In the second clinical approach, two mini-implants are inserted mesially. A screw-suspended TMA sectional archwire is applied (Derton-Perini technique). Two cases, descriptive of the two different treatment protocols, are described. In the first case, the mandibular right second premolar was missing and the adjacent first molar needed to be uprighted. A single screw was inserted distally to the first molar, and an elastic chain was applied. In the second case, the mandibular left second molar was missing and the third molar needed to be uprighted. Two mini-implants were inserted mesially and a fully screw-supported sectional archwire was used to upright and bodily mesialize the third molar. Results: Both uprighting approaches uprighted the molar axis without loss of anchorage. Conclusion: The two approaches to mandibular molar uprighting, developed as rational responses to different clinical cases, were both found to be effective.

Smoke inhalation is the leading cause of death due to fires. It produces injury through several mechanisms, including thermal injury to the upper airway, irritation or chemical injury to the airways from soot, asphyxiation, and toxicity from carbon monoxide (CO) and other gases such as cyanide.
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, ...Jul 27, 2015
www.lung.org > Lung Health and Diseases > Lung Disease Lookup > Silicosis Learn About Silicosis Silicosis is a lung disease caused by breathing in tiny bits of silica, a mineral that is part of sand, rock, and mineral ores such as quartz. It mostly affects workers exposed to silica dust in occupations such mining, glass manufacturing, and foundry work. Over time, exposure to silica particles causes scarring in the lungs, which can harm your ability to breathe. Key Facts There are three types of silicosis: acute, chronic, and accelerated. It occurs in workers from mines, foundries, sandblasting, and glass manufacturing. About 2 million US workers remain potentially exposed to occupational silica. There is no cure for silicosis, but it can be prevented. What Is Silicosis? There are three types of silicosis: Acute silicosis, which causes cough, weight loss, and fatigue within a few weeks or years of exposure to inhaled silica. Chronic silicosis, which appears 10 to 30 years after exposure and can affect upper lungs and sometimes cause extensive scarring. Accelerated silicosis, which occurs within 10 years of high-level exposure. Silicosis can develop within a few weeks to even decades after exposure. When people breathe silica dust, they inhale tiny particles of the mineral silica. This silica dust can cause fluid buildup and scar tissue in the lungs that cuts down your ability to breathe. This can lead to lung scarring and cough, weight loss, and fatigue.
Pericardial window is used diagnostically and, more often, therapeutically for drainage of accumulated pericardial fluid (a condition that most often occurs after cardiac surgery but has many other possible causes). The pericardium envelops the heart like a cocoon; its cardiac filling can be impaired when this cavity fills with excess fluid. When the limited space between the noncompliant pericardium and heart is acutely filled with blood or fluid, cardiac compression and tamponade may result. Pericardial window in combination with systemic chemotherapy may also prevent accumulation of large fluid volumes in patients with neoplastic pericardial disease. [1, 2] Indications The following are indications for a pericardial window [6] : Symptomatic pericardial effusions Asymptomatic pericardial effusions that warrant a pericardial window for diagnosis Hemodynamically stable patients with an undiagnosed pericardial effusion (a thoracoscopic approach is ideal) Coexisting pericardial, pleural, or pulmonary pathology that requires diagnosis or therapy (a thoracoscopic approach is ideal) Known benign effusions that reaccumulate after aspiration Drainage of a purulent pericardial effusion Early fungal or tuberculous pericarditis in which resection of the pericardium is required to prevent future pericardial constriction Use as part of the mediastinal debridement, in patients with descending mediastinitis
http://stop-ear-ringing.info-pro.co ------ Ringing In Ears Dizziness, Can You Get Rid Of Tinnitus, Non Stop Ringing In Ear, Reduce Tinnitus Do you suddenly get up in the middle of the night hearing strange noises? Yes it can definitely be frightening, more so when you cannot find the source. Now consider for a moment that these sounds are coming from within you. Most people would be stunned to know that. Many of us do not even know that our internal organs can make sounds. Let us try to see whether you actually heard these noises or not, and if you did, where did they come from. Now before anything, let us get this straight - yes, you actually heard those noises. No, they are not a result of a creative mind that imagined things in slumber. But having said that, it is also true that there is indeed no source of the sounds you heard. So what is it? Confused? This is a classic case of tinnitus. What is tinnitus? What you experienced last night (or did you just get up from sleep and switch on the computer) is a classic case of tinnitus. This is a medical condition wherein a person hears all kinds of strange clicking, ringing, buzzing, whistling or hissing sounds within the ear. What's so worrisome about this condition for a lot of people is that, there's actually no physical source of these sounds. What makes it even worse is that, no one else seems to hear them. Frankly, these people cannot be really blamed. Naturally, if you cannot see where the sound is coming from, and if you keep hearing it, you are bound to get worried. In tinnitus, the sounds a person hears are actually perceptions. Since there's no actual source, they are often referred to as "phantom noises". Will it help you if you knew that about 8% of all people in the US suffer from tinnitus? Perhaps not, but at least now you know that you are not alone who hears these strange noises.
