Epidemiology

Epidemiology is the process of where one is able to study a disease or disorder. The public health department job is to conduct studies that are epidemiological in nature in order to prevent contagious disease from spreading. An epidemiologist is one who understands the rate/risk ratios, rate/risk differences, and measures the impact on the public.

Each epidemiologist deals in his own science and disciplines when he is taking these factors and measuring them. The discipline requires him to be able to select and use appropriate statistical methods in the analysis of simple data sets and apply these methods by computer using either STATA or EPI-INFO. He must also be able to understand and interpret output from statistical analyses carried out by computer, in relation to research and other questions asked. Then the epidemiologist must present findings based on statistical analysis in a clear concise manner.

The epidemiologist must be able to define a research problem and formulate a study hypothesis and objectives. He must choose an appropriate and ethical study design, plan field procedures, including sample selection, and the design of questionnaires and record forms. A time schedule for the conduct of the study is vital part. The need to prepare a budget is always important for this type of research. A detailed protocol that is of sufficient standard developed into a submission statement for a funding agency.

The epidemiologist must understand the basic statistical measures and concepts underlying the analysis of epidemiological data. He must perform analyses of data arising from epidemiological studies using appropriate computer software. He must be able to identify factors that suggest a disease has an infectious cause. He also must understand the factors determining the spatial, temporal and social distributions of communicable diseases. It is vital that the epidemiologist understand how to measure transmissibility of infections, design, and carry out, analyses, interpret and report an outbreak investigation report. It is of course very vital that the evaluation of vaccine efficacy be investigated.

The study of epidemiology and the use of an epidemiologist are vital for any nation’s health. This is very important for it helps our nation prevent major breakouts of diseases. I would like to say our people do an excellent job in this field and their tasks are not always easy but always necessary. The American Heart Association feels that since heart failure is the number one killer of men and women in America today that our Public Health Department is not fulfilling their duties toward heart related diseases.

In the above description of what epidemiologist, duties are and why we have the study of epidemiology gives a better understanding the medical field problems concerning heart failure patients. The AHA has gathered as much information as possible thru magazines and articles and made a journal for the doctors to refer themselves too. That journal is piece meal at best not complete and not adequate for the care and prevention of heart related problems. That is why we need an epidemiologist from our Public health Department to look at the situation.

My Intralasik Experience

I wanted to investigate Lasik vision correction for myself, and found that there were several options. After talking it over with a great Lasik physician, I decided on using bladeless Lasik, or Intralasik, or Intralase. I cannot say that I decided that for any great technical reasons, mine were mainly psychological.

The advantage of Intralasik over a traditional Lasik procedure is that a laser is used to make a flap in the eye. Every Lasik procedure needs to make a flap in order for the excimer laser to be able to reshape the corner. In traditional Lasik, the flap is made with a microkeratome, which is “a very small blade, not a scalpel”. Well, maybe to you. Somehow, even though both the laser and the blade made the same flap, the idea of someone taking a sharp object to….. well, you get the picture.

In addition (though there is a lot of argument and debate over this) using a laser to make the flap might (let me emphasize might to be fair to everyone) make the Lasik procedure have less chance of getting other cells underneath the flap. I don’t really understand all of the Lasik arguments with regard to this, but I think you should discuss the various Lasik options with the physician. They do vary in cost also.

Before I talk about the procedure itself, let me give a bird’s eye view of myself as a Lasik candidate. In short, spectacular! Seriously, all of the items for a good Lasik candidate could describe me: a healthy guy in my mid-thirties, with moderate nearsightedness and slight astigmatism, with good results on all eye exam tests (thick cornea, no eye scarring or infections, etc.).

I did visit two different Lasik surgeons to get their independent opinions of me as a candidate, and also their description of their services. One of the Lasik surgeons is on the staff at the medical college in a nearby major metropolitan center, so I was pretty assured that their opinions were valid.

On the day of the Lasik surgery I came in, paid my first payment for the procedure, and had my eye prescription rechecked. I was given post-procedure instructions on eye drops, no exercising (yeah!), and to go to sleep after the Lasik procedure. I was given a relaxant, and the Lasik physician and I went to the surgery suite.

The chair has padded pillows to rest and restrict head movement, and a teddy bear to hold if I wanted it. There was a clamp to hold my eyes open, and a suction ring, and then my vision in that eye went a bit dim. The first Lasik laser made the flap, and I focused on a small light while the other laser made the cornea changes. This took less than thirty seconds, or so I was told.

Mainly I was aware of clicking noises and some pressure, but no pain or real discomfort. After the eye flaps were put back in place, I rested in a recliner for about 20 minutes. I could see more clearly immediately after the Lasik operation was over, but was told not to try and test my eyes for a number of days, and rather concentrate on getting them healthy and healed.

I am surprised and immensely pleased it went so easily, well, and pain free. I would recommend this type of Lasik procedure to anyone.

Abdominal Pain in Children

Tummy aches are one of the most frequently complained about problems in children. There are many causes attributed with it, and it is a challenge for the parent or the physician to find out the exact problem. Sometimes the pain requires immediate attention and can also be a case of emergency. The causes can be related to food, infections, poisoning, insect bites, etc.

Bacteria and viruses are responsible in case of abdominal pain due to infections. Gastroenteritis and stomach flu are some of the examples of infections that can cause stomach aches. Gastroenteritis is the inflammation and irritation of stomach and the gastrointestinal passage. Extra care must be taken by travelers, as the food and drinks can be contaminated at new locations and can lead to travelers getting diarrhea. Stomach pain due to viral infections ward off quickly, but bacterial infections demand the intake of antibiotics. In both the cases, some children recover very fast by vomiting and excreting. In case of diarrhea, excess drinking fluids should be given to the kid to avoid dehydration.

Food related stomach aches can be caused because of food poisoning, gas production, excess food ingestion and food allergies. Problems because of food poisoning are temporary and can cause bloating. Symptoms of food poisoning are vomiting, diarrhea, abdominal cramps, and nausea. Usually these symptoms surface within two days of consumption of contaminated food. Depending on the severity chill, fever, bloody stools, or damage to the nervous system can follow. In case of a group of people who consumed the contaminated food, this situation is known as an outbreak. Over two hundred diseases are known to be transmitted via food. Food can be poisoned because of toxic agents or infective agents. Infective agents are parasites, bacteria, and viruses. Toxic agents are uncooked food, exotic foods, and poisonous mushrooms. Food can get contaminated because of handling by unclean workers at the local restaurant, too. Parents should check out the cleanliness and should visit a trusted restaurant.

Particular foods can cause the irritation, such as diary products can cause lactose intolerance. If this is the case, the child is allergic to certain food or drinks and swallowing even a small amount can cause vomiting, nausea, diarrhea, cramping, and skin rash. Since these items are harmless otherwise, such kind of allergic reactions are known as hypersensitivity reaction. Sometimes the symptoms can be life threatening and are known as anaphylactic shock or anaphylaxis.

Poisoning can also be due to overdose of medicines and even due to eating non-food stuffs. Insect bites such as black widow spider bite can also lead to pain in the abdomen. It can be accompanied with muscle cramps, weakness, nausea, tremor, vomiting and in severe case it can cause dizziness, faintness, respiratory problems, and chest pain. Also, the heart rate and blood pressure increases.

In very rare cases, abdominal pain can be due to appendicitis. This is a result of blockage and inflammation of tissues. Young kids have a higher rate if complications are considered and should be immediately rushed to the hospital. The pain starts slowly in the abdomen, specifically near the belly button. The pain shifts slowly to the right side of the lower abdomen within a time period of over twenty four hours. Clear symptoms are abdominal pain, vomiting, nausea, fever and loss of appetite. Diabetes can also be a reason of abdominal pain. Small children usually curl up, cry and express pain through facial expression. Some kids will be reluctant to talk, but the parent should try to get clear explanation of the problem. Along with close monitoring of the symptoms, studying the location of pain, pain duration, nature of vomiting, and urinary problems will help. After that a pediatric should be consulted who can further refer to a gastroenterologist. Until help is reached, the child should be made to relax.
Often, lying with face in downward direction can relieve pain due to gas. Incase of vomiting and diarrhea, fluids should be given constantly. Solid food should only be given when the child is comfortable about eating it.

The Dry Socket

Even though they arent life threatening like bleeding or abscesses, dry sockets can be extremely painful. They are very common following surgery, and happen to be one of the most painful post extraction problems. Dry sockets are more common with removal of the lower teeth than they are with removal of upper teeth. No matter what type of extraction you have performed, a dry socket can occur with any type.

Although there is really no way to prevent a dry socket, you can help to reduce the risk by following your after surgery directions. Even though you may be following the directly precisely, you could still end up with a dry socket. They are known as a quirk of nature, and will make you feel like you are on your death bed – although you really arent. Those who are more at risk to dry sockets include those who smoke following extractions, and those who like to grind their teeth frequently.

A dry socket is a condition where the blood clot that forms after an extraction detaches itself from the socket walls. Sometimes, the clot will dissolve, leaving the bone exposed to food, the weather, and even saliva. Once the bone is exposed, it can become inflamed. The inflammation that occurs is very painful, often times being a deep pain that makes you feel as if you are dying.

If you leave it alone, the dry socket will heal. It will normally take around a month or so, although the pain wont let up during the healing period. If you have a dry socket, youll find that antibiotics and even the strongest of prescription drug wont cure it. An antibiotic will normally cure infections, although a dry socket isnt considered to be an infection.

The best way to fight a dry socket is to go back to your dentist and have him pack the socket. Packing the socket is done without any anesthesia and can be quite painful. It doesnt take long to complete, and it can provide relief from the pain. Once you have a dry socket, you wont care about anything but stopping the pain. The pain can be so intense at times that you will be willing to do anything to stop the pain – even for a few minutes.

Once the socket has been packed, you will be relived from pain for a day or so. If you go back to your dentist, he will remove the old packing, wash the socket out, and place a new packing in. This way, you can get relief from the pain and help the socket heal. Keep in mind that it will take time to heal – and the best way to stop the pain is to do your best to avoid a dry socket at all costs.
