The Process Of Diagonising Bacteria In Urine

admin — Tue, 25 Mar 2008 22:07:39 +0000

Bacteria in urine causes serious disease called urinary tract infections, commonly known as UTI.
UTI is an urge incontinence that involves a strong, sudden need to urinate, chasing behind the bladder contraction that result in leakage.
Usually bacteria in urine causes UTI, they used to live in the digestive tract. They enter into the urethra travel along the bladder and kidneys. Most often, your body removes these bacteria and hence the body shows no symptoms.
Function of the Lower urinary tract, the kidneys and the nervous system is to hold urine and maintain continence. The person should have an ability to recognize and appropriately respond to the urge to urinate.
Urge incontinence is the leakage of urine caused by the bladder muscles that contract improperly or by neurological injuries, neurological diseases, infection, and bladder inflammation.
* Urinary urgency i.e. sudden and urgent need to urinate
* regular urination in day time and at night
* instinctive loss of urine, burning feeling

Signs and tests:
Your urine will be checked here with the help of microscope for bacteria and infection fighting cells. You will have to go through the physical examination like woman will have pelvic exam and men will have genital exam it wont revel you anything abnormal, but neurological abnormalities may be found.
This test provides the following information:
* PVR- which gives the amount of urine left after urination
* Urinalysis or urine content that shows the bacteria in urine that caused the urinary tract infection
* Pelvic or abdominal ultra sound test for woman
* X-rays with contrast dye.
* Cystoscopy, urodynamic studies
* Urinary stress test

Once it has been diagnose that your symptoms are because of infection, Different approaches are used to deal with urinary tract, which is to be cure. Physician will then prescribe you antibiotics, which can kill bacteria causing the infection. Antibiotics will depend on the type of bacteria found in urine.
If it is the initial stage then you will be given 3 days of therapy, if the infection is more serious then prescription will be of more than 7 days. Carefully follow the instructions given.
There are several type of medication used to treat the UTI:
* Anticholinergic agents
* Antispasmodic
* Tricyclic antidepressants
* Oxybutenine and tolteroidne which will make you feel relax

In some cases, surgery becomes necessary to treat the urge incontinence, which is aimed to increase the storage capability of the bladder at the same time to decrease the pressure within it. Usually surgery is appropriate for the patients who have injury. In their bladder or they are having unstable bladder and are not capable of storing the urine.
Is there any possibility of UTI return?
In case of healthy woman it happens rarely, but one out of five women can be infectious with its return. Some women may get three or more UTIs a year. Most often the people who have diabetes they make it difficult to urinate and hence may get repeat infection.

Laser therapy.

Laser trabeculoplasty. Laser trabeculoplasty helps fluid drain out of the eye. Your doctor may suggest this step at any time. In many cases, you need to keep taking glaucoma drugs after this procedure. Laser trabeculoplasty is performed in your doctor’s office or eye clinic. Before the surgery, numbing drops will be applied to your eye. As you sit facing the laser machine, your doctor will hold a special lens to your eye. A high-intensity beam of light is aimed at the lens and reflected onto the meshwork inside your eye. You may see flashes of bright green or red light. The laser makes several evenly spaced burns that stretch the drainage holes in the meshwork. This allows the fluid to drain better. Like any surgery, laser surgery can cause side effects, such as inflammation. Your doctor may give you some drops to take home for any soreness or inflammation inside the eye. You need to make several followup visits to have your eye pressure monitored. If you have glaucoma in both eyes, only one eye will be treated at a time. Laser treatments for each eye will be scheduled several days to several weeks apart. Studies show that laser surgery is very good at reducing the pressure in some patients. However, its effects can wear off over time. Your doctor may suggest further treatment. kaufen levitra

This Is Why Bacteria Are Refered To As An Ancient Form Of Life

admin — Tue, 25 Mar 2008 22:05:26 +0000

Bacteria are single celled, microscopic organisms few micrometers in length. They do not have a membrane bound nucleus or membrane bound organelles such as the chloroplasts and the mitochondria. It does not contain steroids, cholesterol, mitosis or meiosis. The reproduction generally takes by asexual reproduction. Most of the bacteria’s create a single spore when their supply of food runs low. The water gets removed from these spores leading to metabolism. These spores are very resistant to conditions like dryness.

Bacteria are an ancient form of life. Bacteria’s have a wide number of shapes like rods, spheres or spirals, etc. Some of them are so small that they appear as little dots even under a light microscope; whereas some are large enough to be seen under the microscope having spectacular shapes.

Bacteria are present all around us. Under good growing conditions bacteria can grow in length or size slightly, a new cell wall grows at the center that forms two daughter cells each having the same genetic material as their parent cell. If they get a good environment, these two daughter cells get divided into four in just a period of 20 minutes. And eventually, it increases in the order of 1, 2, 4, 8, 16, 32, 64 …

A cell membrane surrounds the bacterial cell that covers the contents of the cell and also acts as a barrier for holding the nutrients, proteins and other important components. They have very few intracellular structures. They do not have a membrane bound organelle in the cytoplasm as they are prokaryotes. They also lack mitochondria, nucleus, chloroplasts and other organelles such as the endoplasmic reticulum and the Golgi apparatus.

There is a bacterial cell wall at the outer end of the cell membrane. These walls are made of peptidoglycan that contains D-amino acids. This cell wall is very important for the bacteria to survive. Bacteria generally have two types of cell wall, Gram-positive and Gram-Negative. In some bacteria’s, an S-layer arrayed protein molecules cover the outer side of the cell. This provides physical and chemical protection to the surface of the cell.

* Decomposition is one of the important roles played by the bacteria. It helps to decompose the remains of the dead plants and animals.
* Nitrogen fixation is also caused due to the bacteria. The nitrogen-fixing bacteria help by replacing the nitrogen in the soil for the green plants to thrive and flourish.
* Bacteria in our body help in the digestion of the food as well as for the production of vitamins. Dairy products like cheese, yogurt, butter milk, etc are prepared with the help of the bacteria.

Bacteria are present all around us. They play a very significant role in our day-to-day life. Many people frequently dismiss bacteria as germs, but don’t forget that it is the bacteria that help us to breathe, produce vitamins and also maintain our atmosphere. Bacteria can be said as an eco-friendly organism.

ANTIRETROVIRAL THERAPY FOR HIV AND AIDS.

admin — Tue, 25 Mar 2008 22:04:32 +0000

Antiretroviral drugs are medications for the treatment of infection by retroviruses, primarily HIV. Different classes of antiretroviral drugs act at different stages of the HIV life cycle. Combination of several (typically three or four) antiretroviral drugs is known as Highly Active Anti-Retroviral Therapy (HAART). Antiretroviral drugs are broadly classified by the phase of the retrovirus life-cyle that the drug inhibits. There are thus five broad classifications of antiretroviral drugs in development, though only the first three classes currently have licensed examples:
* Reverse transcriptase inhibitors (RTIs) target construction of viral DNA by inhibiting activity of reverse transcriptase. There are two subtypes of RTIs with different mechanisms of action: nucleoside-analogue RTIs are incorporated into the viral DNA leading to chain termination, while non-nucleoside-analogue RTIs distort the binding potential of the reverse transcriptase enzyme.
* Protease inhibitors (PIs) target viral assembly by inhibiting the activity of protease, an enzyme used by HIV to cleave nascent proteins for final assembly of new virons.
* Fusion inhibitors block HIV from fusing with a cell’s membrane to enter and infect it.
* Integrase inhibitors inhibit the enzyme integrase, which is responsible for integration of viral DNA into the DNA of the infected cell. There are several integrase inhibitors currently under clinical trial but none are commercially available.
* Entry inhibitors block HIV-1 from the host cell by binding CCR5, a molecule on the viral membrane termed a co-receptor that HIV-1 normally uses for entry into the cell.

These Are Some Of The Ways You Can Use Beneficial Bacteria

admin — Tue, 25 Mar 2008 22:02:05 +0000

Bacteria were the only living organism that existed on planet Earth twenty billion years ago. They quickly settle in different environmental conditions. They reside in the bodies of the live organisms and all over the universe on the ocean floors, ice glaciers etc. Bacteria are mainly linked with disease, death and dirt; they are associated with the many bacterial infections in children and are regarded as the main cause for any disease. They are associated with unclean environment and are believed to spread only infections as well as diseases wherever they reside. However, many beneficial bacteria are used in the production process of many food products.

Bacteria are distinguished in various groups and are usually found in three different shapes i.e. spiral (spirillum), round (coccus) and rod (bacillus) shaped. They are also found in incomplete spirals. The rod shaped and the spiral shaped bacteria are mobile and are seen swimming around in whisking movements. The other bacteria are stiff and are called pilli that serve as a binding. Some of the bacteria can move only in the presence of natural oxygen and the other bacteria cannot function or grow in the presence of natural oxygen. They are found living on other living organisms while some species are found living on natural dead matter. These are disease causing as well as beneficial bacteria.

Bacteria are independent living cells with a membrane that part them from the outside world. They are not viruses and are not harmful and do not cause any health problems. Human body is a home for millions of bacteria and they normally reside on the skin, nose, gut and mouth. Although the stomach and the mouth form the inside, parts of the human body they are in straight contact with the outer world and are the main carriers of the bacterial diseases.

A human cannot live without bacteria, as they are beneficial for the functioning of the body. Bacteria help us in digesting the food, producing vitamins etc. Some diseases like diarrhea are caused by the harmful bacteria, but are soon taken over by the beneficial bacteria so as to lessen the side effects of the medicines which are taken when a person falls sick. Beneficial bacteria are seen growing until any outside factors disturbs them.

From ancient times, people have been eating food that contains bacteria and have been using different types of bacteria in the preparation of food. The oldest and the most famous example of bacterial usage in food preparation are fermented milk products and yogurt. Prime industries contribute in producing bacterial food products like various drinks, milk powder and milk products etc that are beneficial and healthy. Various species of bacteria are need for the preparation of food and food products. The variety of cheese available in the market is mainly produced by using bacteria in the production process. Sauerkraut and sausages are produced by fermenting the bacteria and are also help in obtaining the needed flavor of the coffee beans and cacao. Bacteria are beneficial in many ways and are used by various industries thus helping the world grow healthier

A problem of A.D.H.D

admin — Fri, 14 Mar 2008 23:39:06 +0000

A recent groundbreaking brain-imaging study found that children with attention-deficit hyperactivity disorder experience a development delay with a distinct biological basis. Investigators at the National Institute of Mental Health discovered that areas of the brain’s cortex undergo a thinning maturation process about three years later in children with A.D.H.D. than in those without the condition. Areas that integrate sensory information with executive functions like focused attention, remembering things from moment to moment and controlling movement — functions that are often compromised in people with A.D.H.D. — showed the longest lag time. Estimated to affect millions of Americans — 3 percent to 7 percent of children and more than 4 percent of adults — A.D.H.D. has traveled an extraordinary arc of clinical and public opinion over the last four decades. What began as a relatively unknown disorder became broadly recognized as one of the most common psychiatric problems in children and an increasingly major consideration in adult psychiatric diagnoses as well. A November 2007 M.R.I. brain-imaging study showed an average three-year lag in a brain maturation process in children with A.D.H.D. Affected areas of the brain are involved in executive functions like focus, attention, working memory and control of movement. Despite much evidence for A.D.H.D.’s biological basis, a current of skepticism about whether it is actually a valid medical condition persists. A.D.H.D. problems may persist into adulthood in a majority of cases.

How Antidepressant Drugs Work ?

admin — Fri, 14 Mar 2008 13:52:12 +0000

While not necessarily addictive, antidepressant drugs can cause serious side effects that lead to erratic behavior. Such side effects create a dangerous situation in the workplace, the home, while driving and in many other instances. Those antidepressant drugs of particular concern are tricyclic antidepressants.
Amitriptyline is an antidepressant drug that goes by the brand name Limbitrol. Nortriptyline is also a part of the tricyclic antidepressant family and is prescribed as Aventyl and Pamelor. Doxepin is used to treat both depression and anxiety and can be found under the names Adapin and Sinequan. Desipramine is sometimes also prescribed to treat eating disorders and withdrawal symptoms from cocaine addiction. It is sold under the name brands Norpramin and Pertofrane.
How Do Tricyclic Antidepressants Work?
Antidepressants work by helping to maintain certain levels of neurotransmitters, chemicals called serotonin and norepinephrine in the brain. These chemicals help to regulate mood and modes of thinking. By elevating a person suffering from depression’s mood, antidepressants alleviate the feelings of hopelessness, sadness and the general lack of interest in living associated with their condition. The medication is typically taken as an antidepressant pill, but is also available in syrup form.
Effects of Antidepressant Drugs
Antidepressant drugs, especially tricyclic antidepressant drugs can cause a whole array of side effects. Side effects include, upset stomach, dry mouth, increase in skin sensitivity, insomnia, drowsiness, changes in sex drive, changes in appetite and confusion. Serious antidepressant side effects that require medical attention include constipation, difficulty in speaking, irregular heartbeat, trembling, stiffness of limbs and hallucinations. Tricyclic antidepressants also create an increased likelihood of thoughts of suicide and attempts in children and adolescents. Any sudden behavior changes, mood swings or extreme agitation should be relayed to your child’s doctor.
Signs of Tricyclic Antidepressant Overdoses
Someone overdosing on tricyclic antidepressants exhibits many signs and should be taken to a medical facility immediately. Warning signs of a potential overdose include seizures, dilated pupils, pounding or irregular heartbeat, hallucinations, difficulty breathing, severe drowsiness, and vomiting.
How To Test For Antidepressant Drugs
While antidepressant drugs are a prescription medication with legitimate uses, they can be potentially dangerous to those who work in fields that require the operation of heavy machinery and other hazardous activities. There are many different kinds of drug testing kits that test for tricyclic antidepressants in one’s system, such as urine drug tests, saliva drug tests and hair follicle drug tests.
Having an employee that is under the influence of antidepressant drugs such as amitriptyline, nortriptyline or doxepin can be potentially dangerous, not only to themselves, but to other employees and the health of your company. That is why performing drug tests at your workplace to detect antidepressant use can keep your workers safe, your reputation sound and your company producing to the best of its ability.
As a parent, the prescription drugs your child or teenager is taking is obviously of concern to you. But the potential side effects of some drugs like tricyclic antidepressants are astounding and should be carefully monitored. To test your teen for amitriptyline use, nortriptyline use, doxepin use, desirpramine use and other antidepressant drugs that have been shown to increase the likelihood of suicidal thoughts in adolescents, a drug test kit can help to calm your mind and decide what is best for your child.

Cancer radiation treatment.

admin — Fri, 14 Mar 2008 13:51:47 +0000

Treating cancer can be very complicated, and it is difficult for even the most educated patients to be sure they have the best care. The treatment varies based on the type of cancer and its stage. The stage of a cancer refers to how much it has grown and whether the tumor has spread from its original location. If the cancer is confined to one location and has not spread, the goal for treatment would be surgery and cure. This is often the case with skin cancers. If the tumor has spread to local lymph nodes only, sometimes these can also be removed. If all of the cancer cannot be removed with surgery, the options for treatment include radiation, chemotherapy, or both. Some cancers require a combination of surgery, radiation, and chemotherapy. Although treatment for cancer can be difficult, there many ways to keep up your strength. If you have radiation treatment, know that it’s painless, usually scheduled every weekday. You should allow 30 minutes for each treatment session although the treatment itself usually takes only a few minutes. You should get plenty of rest and eat a well-balanced diet during the course of your radiation therapy. Skin in the treated area may become sensitive and easily irritated. Side effects of radiation treatment are usually temporary and vary depending on the area of the body that is being treated.

Innovation in chemotherapy.

admin — Fri, 14 Mar 2008 13:51:20 +0000

The New York Times reports on a program at the Colorado University hospital to mix up chemotherapy drugs with robots. If successful, this may be the beginning of a substantial safety innovation in the field of cancer care. Chemotherapy is often given in the form of cocktails: either more than one chemotherapy agent or agents with carriers, diluents, and other materials. Dosing must be exact, and there is always the possibility of dangerous errors. By turning the responsibility over to a machine, developers hope to reduce error rates and enhance patient safety. Two companies, Primus Innovations and Health Robotics, are mentioned as collaborating with the hospital in the program. The Baylor Health System in Texas is also pursuing a chemotherapy mixer robot program. A news report says the Colorado doctors think robotic mixing will eventually become the standard procedure at major mesothelioma centers. The CU Hospital will start using the robot in a few weeks. A similar robot has been used in Europe.
