What Is a Peptic Ulcer? What Causes Peptic Ulcers?A peptic ulcer is a hole in the lining of the stomach, duodenum, or esophagus. An ulcer is a sore or erosion that forms when the lining of the digestive system is corroded by acidic digestive juices. It is estimated that between 5% and 10% of adults globally are affected by peptic ulcers at least once in their lifetimes.Reducing World Children Under 5 Mortality: Mixed Progress With Many Regions Not On Track To Meet Millennium Development Goal 4Figures on the progress in reducing world under-5 mortality are released by UNICEF and reported in a comment published Online First and in a recent edition of The Lancet. Generating accurate estimates of under-5 mortality poses a significant challenge because of the limited data available for many developing countries.Brachytherapy Or Conformal External Radiotherapy For Prostate Cancer: A Single-institution Matched-pair AnalysisUroToday.com - Cure of localized prostate cancer requires adequate local treatment. This study shows that brachytherapy achieves cure in 95% by delivering very high radiation doses with acceptable toxicity. The results obtained with 'conventional dose' 3-dimensional conformal radiation were significantly worse, likely due to the lower radiation dose used.What Is Ulcerative Colitis? What Causes Ulcerative Colitis?Ulcerative colitis is a fairly common chronic (long-term) disease that causes inflammation of the colon (the large intestine). It is a form of inflammatory bowel disease that has some similarity to Crohn's disease, a related disorder. The colon - or large intestine - removes nutrients form undigested food and gets rid of waste products through the rectum and anus when we pass feces (stools).What Is Hypothyroidism? What Causes Hypothyroidism?Hypothyroidism, also known as underactive thyroid, is a condition in which the thyroid gland, which supplies hormones to keep the metabolism in working order, is not functioning properly. This results in lower-than-required levels of essential hormones that are distributed to the rest of the body - undermining the body's ability to function efficiently.Scientists Find Way To Make Bacteria More Vulnerable To Existing Antibiotics A team of scientists in the US reports they may have a found a new way to make bacteria like MRSA and anthrax more vulnerable to existing antibiotics by interfering with a defence mechanism that the microbes use to resist the oxidative stress imposed on them by antibiotics. The discovery was led by Dr Evgeny A.Adult Obesity Linked To Childhood Emotional Problems A UK study suggests that children with emotional difficulties are at higher risk of becoming obese when they grow up, and while the researchers said the findings don't show that emotional problems like low self esteem, being overly worried or feeling less in control of one's life in childhoodAfrican Children: Vaccination Against Various Bacterial Diseases Is NeededAn article published Online First and in a future edition of The Lancet reports that the organisms causing bacterial infections in African children with sickle-cell anaemia are the same as those in developed countries. Vaccination against these bacterial infections could considerably improve survival in these children. Vaccines are already available in developed nations.Improvement In Survival For Children With Acute Lymphoblastic Leukaemia With Dexamethasone-Based TherapyAn article published Online First and in the October edition of The Lancet Oncology reports that a dexamethasone-based treatment reduces the risk of relapse and improves the rate of cure in children with acute lymphoblastic leukaemia (ALL). This can be achieved without the use of cranial radiation and some commonly used chemotherapy drugs, therefore minimising the risk of unnecessary side-effects.Swine Flu Vaccine Study Says One Shot May Be EnoughA new study from an Australian vaccine manufacturer suggests that just one shot of vaccine may produce a robust enough response in the immune system to protect people from being infected by the 2009 pandemic A/H1N1 swine flu virus. The news is expected to be welcomed by health authorities because it means more people can be protected more quickly as vaccine becomes available.UK Among Losers In Europe's Heart Disease League Table New research reported at a European heart conference this week points to large disparities in rates of death due to heart disease among 16 European countries, with the UK showing up among the losers in many of the league tables: the report also highlights huge inequalities in those countries' cardiovascular disease prevention policies.How Significant Is The Bleeding Toxicity After External Beam Radiotherapy For Prostate Cancer Patients On Anticoagulation Therapy?UroToday.com - Prostate cancer is the most common cancer among men, especially in elderly men. Since these men often also have cardiovascular diseases that require anticoagulation therapy, it is not uncommon for prostate cancer patients to be on anticoagulants, such as Coumadin and Plavix.New Obesity Drug Qnexa Showed Positive Results In Late Stage Trials Test Says Company According to Vivus Inc, their experimental drug Qnexa for treating obesity showed positive results in late stage trials, where patients who took the new diet pill, a combination of phentermine (a stimulant) and topiramate (an anticonvulsant), shed an average of nearly 15 per cent of their body Phase III Trial Tests Once-daily Edoxaban In Atrial FibrillationA major phase III trial - ENGAGE AF-TIMI 48 - is investigating once-daily treatment with the new oral factor Xa inhibitor edoxaban in patients with atrial fibrillation (AF) with the potential for providing substantial improvements compared to the current standard of care in preventing stroke, specialists announced this week.Yale Researchers Succeed In Repairing Brain Damage Caused By Chronic Stress, Lead Poisoning, Potential Implications For Bipolar DisorderYale University researchers report in the Proceedings of the National Academy of Sciences (September 7-11 edition) that damage to the brain caused by chronic stress or lead poisoning can be repaired by blocking a key molecular pathway. Research shows that rats exposed to chronic stress develop damage to the prefrontal cortex.What Is Dyspepsia? What Is Indigestion? What Is Upset Stomach?Dyspepsia, also known as indigestion or upset stomach, is a term that describes discomfort or pain in the upper abdomen. It is not a disease. Dyspepsia is a group of symptoms which often include bloating, nausea and burping. Indigestion is usually caused by stomach acid coming into contact with the mucosa of the digestive system - the sensitive protective lining of the digestive system.New Monkey Malaria Potentially Fatal To Humans Researchers in Malaysia have found that an emerging new form of malaria, thought previously only to infect monkeys, that can be easily confused with a less serious type, is widespread among humans in the region and is potentially fatal if not diagnosed and treated early.Making Stem Cells From Liposuction Leftovers Is Easier Say Researchers Writing in a new study, US researchers said it was easier and just as safe to make stem cells from fat cells freshly isolated from patients, for instance from cells present in liposuction "leftovers", than it was to make them from skin cells as other studies have done recently.Most People Will Not Need Flu Drugs, CDC In a bid to make the most effective use of Tamiflu and Relenza and stop people hoarding and overusing them like some did when swine flu first broke out earlier this year, the US Centers for Disease Control and Prevention (CDC) said yesterday that most people will not need drugs if they get the flu this season and neither should they expect to have them.What Is Arrhythmia? What Causes Arrhythmia?An arrhythmia is an irregular heartbeat - the heart may beat too fast (tachycardia), too slowly (bradycardia), too early (premature contraction) or too irregularly (fibrillation). Arrhythmias are heart-rhythm problems - they occur when the electrical impulses to the heart that coordinate heartbeats are not working properly, making the heart beat too fast/slow or inconsistently.
