Stomach Pains

 

 

Stomach pains is a common problem that often causes people to go to the doctor.  Stomach pains can actually be due to conditions other than problems of the stomach.  Structures such as the pancreas, gallbladder, intestines, and many other structures are in the vicinity of the stomach and can cause similar pains and problems.  It is important to keep this in mind since the treatment of these conditions can be very different.

Most of the time, only a trained physician can narrow down the cause of your stomach pain.  Although stomach ulcers, gastritis or inflammation of the stomach lining and heart burn can cause stomach pains, more serious conditions such as cancer or problems of other nearby organs can also be the root cause.

Some of the common causes include pancreatitis which is an inflammation of the pancreas.  This most commonly occurs because of drinking too much alcohol or gallbladder stones blocking the tube that goes from the gallbladder to the intestine and pancreas.  Your doctor will order special blood tests to diagnose this condition which can potentially be life threatening.

 

Gallbladder stones can sometimes be a cause of pain in the region of the stomach.  The stones can block your gallbladder and cause intermittent pain or inflammation of the gallbladder wall.  If your gallbladder stones are causing you problems, you will likely need it removed.

Inflammation of the stomach lining or gastritis can also cause pain in this region.  Ulcers, reflux of stomach acid into the the esophagus can also cause pain in this region.  Often these conditions are further investigated with endoscopy by a gastrointestinal specialist.  Blood tests are often done to exclude pancreatitis and other inflammatory conditions.  Imaging such as ultrasound is done to look for gallbladder stones and other inflammatory conditions of the abdomen.  As always, only your doctor can properly diagnose your condition.  An early diagnosis will lead to a better outcome so see your doctor.

Match Day In Medical School

Match day is usually in March of the 4th year of medical school.  Medical students find out where they will be spending the next 3 to 7+ years of their life training to become doctors.  Medical students get envelopes during the match day ceremony with their residency locations.  A long process has led up to this day so it is a huge relief.

It all starts with choosing your specialty which in itself is a difficult task.  As a medical students, you have relatively limited exposure to many specialties.  Also the exposure is not what it may be in the community setting since you do your rotations in large tertiary centers.  Next you must apply for internship and residency in some fields.

This will involve getting letters of reference, a deans letter which summarizes your medical school experience, and your licensing exam test scores.  You will also write a personal statement.  interviews will come next.  This usually involves traveling to distant locations in some cases.  The interview day can be an entire or even multiple day affair.

After going on multiple interviews, you then decide on your top picks for residency training.  The residency programs also decide on their top candidates.  A computer then develops a match according to an algorithm.  The wait after submitting your rank list is painful.  But the day will finally come when you find out where you will be doing your internship and residency.

Many US medical students get one of their top three choices.  In some cases, medical students do not match to their specialty of choice.  This usually happens when the medical student applies to a competitive specialty or is not competitive for the specialty they are applying for.  In these cases, there is a scramble some days later.  All unmatched medical students scramble for the unmatched residency positions.  Often these are in a different specialty for the competitive fields.  After all this work, most students are happy with their place of training and choice of field.

Ophthalmology Rotation In Medical School

The ophthalmology rotation in medical school is usually taken during the fourth year as an elective.  This means that is it usually not required but the student chooses to take it.  The rotation is usually 2-4 weeks.  This is just enough time to get the students feet wet.  Unlike many rotations, this one is heavily outpatient based.  The rotation often takes place in a clinic setting since much of ophthalmology is an outpatient field.  There will also be some exposure to the operating room.

In clinic, you will most likely shadow residents seeing patients.  The residents will examine the patients and then present to the clinic attending.  As a medical student, your involvement will not be very heavy particularly if you are there for such a short time.  During the rotation you will likely be exposed to the more common problems seen like cataracts, glaucoma and the like.

Students who wish to enter ophthalmology as a field may take more rotations including an outside rotation.  Since ophthalmology is a competitive field, the student must get top grades and really shine on their rotation.  For many other students, this is more of a laid back rotation.  There is usually not a test at the end like for the core clerkship rotations taken during the third year.

During the rotation, a lot of teaching will be from the resident and less so from the attending physician.  There may be some teaching if there are inpatient consults from the attending.  You may learn how to do an exam with an ophthalmoscope.  This may be a skill you will need in the future since the ophthalmologist may not be available at all times.  This is a good rotation to take for many students interested in clinical specialties, since during residency training, exposure is often limited.

Operating Room Experience As A Medical Student On Surgery

Being in the operating room is one of the more memorable experiences I have as a medical student.  While most of the surgery rotation involves taking care of inpatients, attending to emergency room patients, etc. being in the operating room is what surgery is really about.  For just a moment, when you scrub before entering the operating room, put on the gloves and surgical gown, you feel like you are a surgeon.  The operating room is very orderly with nurse and technologists attending to their duties.

When the operation begins, the attending surgeon may actually allow you to make the initial incision.  From that point on, it is more common to hold retractors and just watch.  Occasionally you may be asked questions.  The resident who is in there with you will usually get to do most of the operation under the watchful eye of the attending.  Watching the surgeon bark commands at the surgical nurse is interesting.  All those names of the instruments and when to use them.

Some of the surgeries last for hours.  I remember my back and shoulders getting really tired holding those retractors and instruments.  There are no bathroom breaks either.  I do not know how I would go for hours not having to use the bathroom but somehow you do not need to most of the time.  Your appetite also goes away.  Maybe it is the excitement and energy during the operation.

When the surgery is finished, I remember suturing the incision with the residents.  I think this is where I really learned to do this.  This skill would serve me well later when I rotated in the emergency room having to suture laceration.  Most surgeons are nice and good to work with.  There are some bad apples who will yell at you and make you feel stupid.  It is probably the stress of the job making their bad side show.   Overall, you work like a dog but learn a ton and start to feel like you are really becoming a doctor.

First Night On Call As A Medical Student

Although it has been many years for me, I still vividly remember the first night on call as a medical student.  I was on my first rotation during third year on internal medicine.  Internal medicine forms the basis for the practice of medicine.  This is where you develop your doctoring skills.  It was July and I was on with some fresh interns and a senior resident who was available.  I had a wealth of book knowledge, none of which was practical.  I had no idea how to actually work up a patient and admit him.  I could tell you the pathophysiology of diabetes however.

I had worked an entire day on the inpatient units.  When everyone else was going home, I would stay for an additional 12-20 hours.  It was 5 pm and it was time to help cover any inpatient admissions from the emergency room or doctors offices.  Our first call came shortly after.  An elderly man who had an exacerbation of his heart failure.  I remember spending more than an hour in his room examining him and talking to him.

I was too polite to cut him off, but he was very wordy.  I think I heard his entire life story with a few scant details about why he was in the hospital that night.  I was extremely tough to get any past history.  The exam I did was thorough but did not lead to any clear diagnosis.  I remember writing the intake note multiple times trying to get it perfect.  During this time, the interns and residents had admitted multiple other patients.

They asked me to admit another patient around 1 am or so.  This was another elderly man in his 90s with a COPD exacerbation.  He was accompanied by his son who knew exactly what was going on.  This one was easier.  I had little sleep that night because there were other issues to attend to with the intern on already hospitalized patients on the unit.

Once morning came, I has to present my patients to the well rested attending and the team of intern, residents and other medical students.  Boy was I tired and sleepy.  I presented the patients and everything seemed to go well.  I was wordy and did not get to the point.  The attending knew right away what was going on but listened to me patiently. I would be on call every 4th night for 3 months.  Doing the same thing.  Admitting patients, attending to calls form the nurses and emergency room.

Although the rotation and call is particularly difficult, this is where you learn to be a real doctor.  While many of us go on to specialize in narrow areas, every doctor in this country needs a basic foundation of internal medicine.  With time, I became more efficient and began to admit patients quicker and more confidently.  You really learn how crucial it is to be a team player and help out no matter what.  You are the lowest man on the totem pole and you need to remember this.

Gastroenterology Rotation In Medical School

The gastroenterology rotation in medical school is usually taken as an elective in your 4th year.  Gastroenterology is a subspecialty of internal medicine.  Physicians in this specialty complete 3 years of internal medicine followed by 3 or more years of gastroenterology training.  Gastroenterologists treat diseases of the gastrointestinal tract and its associated organs such as the liver. pancreas, and bile ducts.  Gastroenterologists main procedure is endoscopy which can be of the upper gastrointestinal or lower gastrointestinal tract.

Medical students must know far in advance that this is a specialty that may interest them.  Since they must first complete an internal medicine residency.  The rotation in medical school will usually be in a teaching hospital.  The medical student will be on a team of physicians in various levels of training and an attending physician.  The medical student will likely get heavier exposure to the inpatient units.  Often, this will consist of consults on inpatients with gastrointestinal illnesses and issues.

The medical student may be the first to see the patient.  He will obtain a good history and do a physical examination.  He will have to review any tests that have been performed.  The medical student may then have to present the patient to the resident, fellow and attending.  This may consist of the history, physical exam, assessment and plan.  The medical student does not need to get this perfect.  But it should be well organized and researched.

The medical student will help follow up on these patients by obtaining labs and seeing them everyday with before the team sees him.  The medical students exposure may also include clinic days.  Although usually this is less emphasized.  This may include more healthy patients with gastrointestinal illnesses like inflammatory bowel disease.  Usually the rotation is for a month so the student only gets his feet wet.

The grade will be dependent on how well the student participated in the team and helped.  How well he interacted with and worked up patients.  How much knowledge he had relative to other medical students.  At the half way point, it is always fine to ask how well you are doing and if there is anything you can do to improve your performance.

Yearly Market Returns Are Not that Relevant For The Average Investor

One of the most important numbers investors use to evaluate funds is their annual performance.  But few investors put all their money into their funds on January 1st every year. Also, the average investor jumps in and out of funds depending on their performance, newsletters, friends tips etc.  Therefore this figure of annual returns, or 5 year returns gives you an idea of how well the fund has performed but few investors actually achieve this return.

Many investors place money into funds every 2-4 weeks as their paychecks come in.  This can be in the form of 401k contributions or money placed into a taxable account.  The market is volatile.  It has large swings, sometimes on a daily basis.  If you happen to place you money into the funds when the market is relatively low most of the time, you will achieve an annual return which is higher than that posted by the fund at the end of the year.  This will be strictly on the basis of luck however.

Market timing has been shown in multiple academic studies to be nearly impossible to do over a long term.  You must know when to pull your money out and also know when to get back in.  That means you have to get it right twice.  Markets follow a random path most of the time.  The markets often have no rational basis for the moves they make.  Seemingly good news may drive the markets down or not at all, while seemingly bad news can make the market spike at times.

The best thing to do is to keep investing into the same funds.  Perhaps rebalance your funds yearly.  Avoid market timing based on tips from the pros.  No one knows for sure what the markets will do.  Do not chase performance.  Past performance of funds has almost no relevance on future performance.  Remember that if you invest over time, you will get both low and high prices.  If you are lucky, you may get an even better return than the fund posts at the end of the year.  If you jump in and out of the fund, in most cases you will do worst than the annual return.  This has been shown in academic studies.

Perfect Portfolio (Well Almost)

Most physicians have little time to research stocks, bonds, alternative assets, hedge funds etc.  Advisers charge a large sum of money often and provide little benefit beyond what the markets offer.  It has been shown in multiple academic studies that active managers rarely beat their bench marks over time.  Advisers charge up to 2% of assets per year or more on top of mutual fund fees.  This will compound over time just like gains and result in anywhere from 1/3 to 1/2 less terminal wealth after say 30 years.

The first thing to keep in mind before you invest on your own is to accept the fact that few advisers will outperform their benchmarks and you can not know which ones will in the future.  Those who have in the past often do not do so in the future.  Next, you must be willing to accept an index strategy.  That is, get exactly what the markets offer every year at the lowest cost.  This way, there is no manager making potentially bad decisions and risking your money.  Investment costs are kept to a minimum.  This is one of the only things you can actually control.

Once you truly believe in index investing on your own for the long run, you can then set up a very low maintenance, tax efficient, low cost portfolio which has been shown in academic studies to outperform the great majority of investors who use advisers and chase after the hottest funds and strategies.  One of the companies offering the cheapest funds is Vanguard.  If this is not an option for you than consider Fidelity or Schwab to name a few.

All you have to do to beat 95-99% of investors is to place 60% of your money in stocks and 40% of your money in bonds.  You can place 60% of your stocks into a total market fund and 40% into an international fund which includes both small and large cap funds like Vanguard’s total international fund.  For bonds, you can use something like Vanguard’s total US bond market.  There you have it.  A portfolio you can keep forever at a low cost.  It is tax efficient and will beat the great majority of investors over the long run.

Investing should be boring.  The only downside I see is that you may not have much to say at the next cocktail party when Dr. Jones is bragging about his investment in the hedge fund which returned 20%.  But what benchmark is that hedge fund using and how much in fees do they charge?

How To Be The Best Patient Possible

We all want to be seen by the best possible doctor who listens to us and has the latest knowledge of medical diagnosis and treatment.  But it is important to try to be the best possible patient also.  Although the great majority of doctors will treat you as best as they can no matter what, if you give a little extra effort, this may motivate the doctor to go the extra mile for you.

To be the best possible patient, you must be an active participant in your care.  You have to provide a good account of your symptoms and complaints.   When the doctor gives you a diagnosis and treatment, you must be able to fully participate in the care and be compliant.  When you see the doctor again for follow up treatment, you must have truly stuck to the treatment without fail.

If the treatment is not working, then it is fine to ask for alternative treatments.  There is no need to challenge the doctor in an adversarial manner.  Work together as a team with your doctor.  If you see an alternative therapy on the internet, it is fine to ask the doctor why they think this is not a good option for them.

If you truly do not like the doctors bed side manner, then there is no need to be rude to the doctor.  You can switch doctors to one who is a better fit.  If you have had a bad outcome with a doctor from a procedure or surgery, this may be expected.  Some bad outcomes or complications are not avoidable and a risk you take by undergoing the procedure.  If all else fails, then you may want to discuss any shortcomings in your care with doctor.  The doctor may be very receptive to either adapting his care or perhaps providing you an additional provider to see.

Cancer Spreading To The Bones On Chest X Ray

Cancer is a disease that is one of the major killers of people in this country.  Cancer can occur in almost any part of the body but is most commonly due to lung, colon, and breast to name a few.  Cancers grow over time and can spread to other organs, lymph nodes, and bones in the body.  Chest x rays are commonly done on patients with cancer to evaluate any new symptoms or monitor for cancer recurrence.

Chest x rays are usually done in 2 views.  One of the views is straight on and the other view is usually taken from the side or a lateral view.  Chest x rays are usually performed by technologists and interpreted by radiologists who are specialty trained physicians.  When an abnormality is identified, sometimes additional imaging tests are needed such as a chest CT.

Chest x rays show the bones of the chest.  These include the ribs, the sternum, the vertebra, scapulae, and clavicles.  These bones are normally white in density.  When cancer spreads to the bones, this takes the form of either a dark spot or a whiter spot than the normal bone.  Sometimes spread of cancer to the bones has the same density as the normal bone and can be difficult to see on a chest x ray.

Spread of cancer to the bones usually means there is a worst prognosis than if the cancer is isolated to the organ of origin.  Often chemotherapy may be needed.  There is the risk that the bone can break since it is weakened by the cancer.  There can be pain associated with spread of cancer to the bones.  Other tests to determine the extent of the spread of cancer to the bones include bone scans, PET CT scan, and MRI to evaluate a single area more closely.  As always, if you have cancer and bone pain, you should see your doctor right away and discuss your case.  You may need further imaging.  You may also need monitoring for spread of cancer to the bones depending on your specific diagnosis.
