I gotta say that this was a successful event, organized by my ex-roommate (already ex) Leed Wi and Helmi. Of course with all the needed helps from lotsa comrades and friends. I guess everybody there that afternoon wanted it to be wonderful.

The place wasn’t really big but I guess you can have that cozy feeling that every table you turn to, there is a friend. At least a friend. Hehe.

Leed Wi and family.

Hui Qian who took care of the slide show and music. p/s don’t be upset with what people say, they didn’t contributed anything.

Theenesh who gave a wonderful speech.

Erica, the one I pulled along.

And her signature water bottle.

First of all I would like to begin by saying that this is my personal top 5 most used applications on my iPhone/iTouch. I think these 2 Apple products are really made for those in the medical line.

Problems - I think that iTouch is better in term of using it like a PDA compared to the iPhone. I had this problem of using losing my signals frequently after installing some ‘bad’ applications that temper with the network. Since iTouch can not be used to call, it doesn’t affect its performance at all.

I’ll start with the list now

1. Lexi Complete

This is like the King of all medical apps on iPhone/iTouch. It includes - Lexi drugs, Pediatric Lexi-drugs, Nursing Lexi-drugs, Pharmacogenomics, Natural Products, Infectious Diseases, Lab & Diagnostic Procedures, Harrison’s Practice, 5-Minute Pediatric Consult, Stedman’s Medical Dictionary, AHFS Essentials, Poisoning & Toxicology and NBCA Exposures. Jaw-dropping right?

The Harrison’s Practise by itself could already give you all the information that you want about anything you could think of. I found Lexi-drugs to be quite handy but the Stedman’s Medical Dictionary will definitely come into handy all the time. Lab & Diagnostic Procedures is very specific and detail in all the lab test and even give you info on how to do it and what are the main principles.

2. 5-Minutes Clinical Consult

I found this very useful as well. If I couldn’t find the thing that you are looking for in the Lexi-complete, this is definitely the 2nd place that I’ll look for. It provides longer and more detail information. (Please bear in mind that ALL of the information given is really quite complete and long. A lot of readings!)

3. MedCards

It is a compilation of useful diagrams and scheme or procedures that you would like to have on your palm when you are doing stuffs.

All these normal lab values.

4. MedCalculator

Not using this yet but I think it is going to be handy in the future!

5. Flashcards

Really useful when you are bored and waiting to go to sleep on the bed. Playing with the flash cards could be quite useful as you could remember some of the info better and maybe find a few new things as well!

-Extra-

Discover

I put this in as one of the ‘medical apps’ because when this is used together with ‘DiskAid’, you could put all those word files that you have into this device and read it any place you one. A good plus point about Discover is that if the word files are too long and you stopped somewhere in the middle, you could always bookmark that point and start from there the next time you want to read it instead of scrolling down and look for the place that you stopped.

Well, some very interesting video. So whether the vaccine is good or not? It is hard to say.

Long time didn’t post up something like this. Come, medical students, tell me what you see and how many instruments you can name!

Answer by end of this week :)

Dear Dr. Grissom,

Even thou my letter to you will not be read but I feel like it is good to let me express my feelings in my blog. It is definitely a disaster when I know you quit from the department not long ago.

I would like you to know that I do think you are the best in your team. Even thou you have a tummy that mostly girls nowadays would not like but seriously if I am to grow up having a tummy like yours, I would want to be like you! Talk like you, walk like you, stay calm like you and smart like you. After getting to know you, I would put you one rank higher than Dr. House! So, how can you quit?

I do understand that being able to find the love of your life is indeed the luckiest thing ever that could happen to a man but I sincerely hope that you could return to the team or perhaps appear as guest professor (provided that it is going to be often) or I’m going to abandon this show!

Everybody loves you! Everytime I start singing ‘who are you’ in the corridor, Claire would follow up ‘who!? who!? who?! who?!’ whenever she is at home (my apartment is small). See! I love the show because you are in it! You have such a high place in our heart!

I hope that you could get back to CSI. If not, I think the show is just crappy. Because all the others do not look smart! Only you have the face of a CSI. It certainly would not be too exaggerating that I’m watching the show because you are in it. (well, if you appear in other show, I wouldn’t watch them, so you MUST appear in CSI: Las Vegas)

Your sincerely,
Peanut

p/s: okay, I’m going to find some forum and take part in the ‘why Grissom quit discussion’ and show my beh-syok-ness.

Regarding to the previous post when my ‘friend’ who photocopied my work and passed up as his, today, I found out that he is not the only one doing that. I saw the ‘my’ paper being used as ‘their’ work for at least 5 of them!

I decided to confront him by ’signaling’ to him that how come my paper is with the other group of people (I have no doubts my work will later be sold in ‘black market’ for the coming years for their juniors and so on, yea, they are THAT useless to do their own homework). He had a look at them, and gave a ‘troubled’ face (as in showing me he didn’t know how did that happen) and continued talking and playing around like kids. He is so ‘obviously’ do not care about what happens next as long as his work is done and he is safe to get the sign tomorrow for the exam.

No I didn’t talk to him and didn’t express my anger too much.

No I didn’t curse him aloud (only inside my heart, which kinda pollute my cute and kind cardiac muscles).

No I didn’t took a knife and stab him (even thou my brain ran over the scenario few times and think how the forensic experts are going to catch me if I do that).

Yes I proceeded to think what is the perfect way to kill somebody.

Yes I ended up thinking that it is IMPOSSIBLE. Sooner or later people will know about it.

Luckily this is only homework, and not something which I would want to protect with my life.

BUT

He is so going to suffer for every single chance that I have in the future. DAMN IT!

And now I should pray for the strictest teachers my uni can offer to be our teacher in the coming sem. Even thou I’m going to suffer, I’ll be happy to see him suffering more than me.

Yea, I’m those kind of people who are happy to see him suffer.

I’m THAT EVIL!

Okay, enough for the hate. I’ll keep that to myself and update you all about what I do to him after on. Mean while, let’s have some snowy great weather picture to sooth the day.

Near the river bank.

See that Lenin’s face on top of that building?

It is a sunny day!

p/s - my housemates are still in Opthalmology exam. Hopefully they don’t get mentally molested by their teacher.

I had blog about the lack of knowledge about weapons before. Well, seriously, I personally think that Malaysians youngsters do not talk about guns and tanks and bombs during mamak session. This is actually a good thing I guess. Sometimes when I was sitting in lecture with my Russians batchmates and overheard their conversations, besides cars, they like to talk about firearms and bombs and tanks. Weird right?

Anyhow, I remembered when the doctor (who I idolize) who I met during the selective in India said that he had his ‘new found knowledge of psychiatry’ when he gotta treat a psychiatry patient with dystonia and possible psychological trauma after an attempt of rape (despite the fact that we are living away from the city, they have 1 or 2 psychic patients per week!), today is the day that I have my new found knowledge of ballistics in forensic medicine.

I love it when the teacher knows how to put their material nicely and talks only about the interesting things and believes his students to study the basics at home (come on we are all grown ups already).

Definition of firearm - A weapon, especially a pistol or rifle, capable of firing a projectile and using an explosive charge as a propellant. In term of medicine, 4 components are considered the main factors - mechanical, thermal, chemical and sound.

On a firearm, the column (main empty tube) of the gun can be smoothed or rifled (specially threaded). The smooth column are usually use with blunt bullets and is considered the classics (mostly used in hunting, or the shotguns). The rifled or specially threaded column is kinda like the new generation’s firearm, giving the bullet (usually sharp headed) the ability to spin, another element that make it more deadly.

When the trigger is pulled, the part of the capsule containing the explosive charge will burn up and create such big combustion in such small space that the energy was transferred on the bullet which push it out through the column. Some of the left over energy will be used to mechanically reload the next bullet (automated rifle) and continue firing until you let go of the trigger, or used to reload the next bullet (submachine gun) but will not fire until you pull the trigger again.

A normal pistol could shoot a bullet with a starting velocity of 200m/s, and the proud Russian AK-47 - almost triple the speed of a normal revolver or pistol. A sniper’s range can reach 2km.

The entering wound on a body would be very small. But once a bullet passes through the skin, it has the ability to be deviated into another body structure and finally end up blindly in the body, or travel all the way out from the other side of the body (possible in another level), creating a bigger tissue defect.

The molecular theory of the big impact created by the bullet also stated that the diameter of its influence could be 6 to 7cm (depends on the distance). It means, if you are shot by an AK-47 bullet, which is actually 3cm away from your ribs (intercostal space), it is possible that your ribs could be fractured, by the molecular impact caused by the bullet on the nearby soft tissue.

Let’s look at the protective vest instead. It basically have no use against the shooting done by AK-47. Even thou the bullet didn’t pierce through the body, the impact and energy given is big enough to fracture your organs and ribs. Remember, E=mc2(square), energy does not disappear into thin air.

Plus a gun wound is always considered an infected wound. A shot on the leg which break the femur would basically means amputating the leg if one wants to survive.

No, Rambo doesn’t exist.

No, happy ending in movies with the existence of guns doesn’t exist.

No, Mission Impossible is fake.

Yea, Hollywood movies are lame. Feeding us wrong information and wrong science yet we choose to believe them blindly.

In the end, I wondered, why all these are created.

In order to subdue a demon, you need to change into a demon eh?

AK-47 (AK actually stands for the creators name - аппарат колашниково) that can be semiautomated or automated as you like, never jams, 700m/s to 900m/s, almost 2km range and shoot even in water.

It is crazy to blog about Public Health, but I think I found the hardest statistic question out of the 13 statistic questions in the list. Have a look at Q43. I personally think that this is the hardest because you gotta know the Basics and the answer for this question is 12 pages of photocopy papers. For those that have problem with it, I’m attempting to shed some lights. I just think it is quite an achievement for me to finish reading this. Now time to vomit them out again. Fasten your seat belt for a damn long answer.

Q43. Измерение связи между явлениями и признаками. Корреляция.

Корреляция означает соотношение, взаимосвязь между признаками. In normal would be a thing that can find out the relationship between 2 features. Normal relationship/hubungan between 2 feature (признаки) can be divided into функциональный (which usually used in physics when the relationship between 2 things are shown with a line graph) or корреляционный (when one bacaan can have more than 1 numbers, for example: think of the baby height-weight chart in the hospital, the 1 height tak semestinyer have only 1 corresponding weight, they can have a few).

So корреляция deal with the second type of relationship (связь) where 1 feature(признак) can have more than 1 corresponding feature(признак). And to find out the relationship, you need a coefficient, which in this case is called the коэффициент корреляции.

The coefficient is positive (+) is the correlation is positive (macam increasing graph, the more x is, the more y is). And if it is negative (-), the correlation is the other way round (when x increases, y decreases). Easy? Fun part yet to come.

To see how strong is the correlation/relationship/связь of both of the feature (for example the weight and the height), there is a степень сопряженности. It is given in from the number 0 (no relationship at all) to 1 (полная связь).

Example of the meanings of positive and negative signs and their numbers.

Ok. After knowing how to read the number, it is time to see the formula. Коэффицентт корелляции:

This formula is use when the amount of data u collected is less than 30 (n<30). dx and dy is the difference of X and Y from their средная арифметическая (Mx and My). Easier to see how they are counted when you see table. 32 in the papers that you have.

Everything is counted out in the table.

Well. After you get the result of your calculation, you are now able to say whether the relationship between these 2 features that you researched about is strong or not. Now, remember, the numbers of data that you use is less than 30. Now you would wanna test whether the result that you get is going to be the same or not if you have a data of, let say, 100,000 people. This is why the following formula is created, the ошибка коэффициента корреляции. Always remember ошибка means that how your result of a limited numbers of data would perform in a bigger general data (соответствие размера связи в генеральной совокупности).

Now the formula of ошибка коэффициента корреляции

Here we are suppose to count the ошибка which will put in the ‘t formula’ to count out the критерия t which can tell us how good this whole relationship functions in a bigger general sum of data. To read t, you need to look at table 26 in the book (can’t find it but need to dig for it).

So THAT is first part of the question. To make this process faster, I’ll type only the important information.

We had already counted out how well the relationship fits in a bigger picture. Now, what if one of the feature is not numbers but some words like (small, medium, big)?

We use the коэффициент ранговой корреляции which functions EXACTLY the same like those formulas above, just that now we are dealing with ‘qualities’ instead of ‘quantities’. We rank the qualities like shown in table 36 in the paper and calculate the formula. And because this is the SAME like the above formulas, after calculating the coefficient, you will need to count the ошибка and the критерия t as well with their own formulas.

Now the final part of the question (phew.. this is the reason why I think this is the hardest question!).

Now you have the coefficient. Remember the normal XY formula that we studied in secondary or primary school? y = kx + c. Now you have the коэффициент which in this case is the ‘k’, you now can put in a value into x and see what comes out as y.

This in this part of the statistic is called регрессия - функция, позволяющая по величине одного корреляционного связанного признака определить средние величины другого признака.

Use the coefficient that you get to count out this another коэффициент регрессии which later on can put into the formula to count out any value that you want!

Use the coefficient with the formula

y = My + Ry/x (x-Mx)

and walaaaa…. you get the classic function formula of all graph and maths.

Don’t be too happy yet. One more part. Now you have the function, you will need to see how wide they oscillate for each of the feather. Remember the height-weight graph at the beginning of this post? A number has multiple corresponding number to it. To find that, you use the сигма регрессии formula. (need to know how to count sigma, that is suppose to be QUESTION 39!!!!)

Wala, now you have the one last useful formula that enables you to plot the whole graph for whatever you want to plot (for example the height weight graph in paediatrics).

-THE END-

p/s

I kenot understand who says public health is easy?
I understand why I need to learn this.
Yet I hope I don’t get this question.
If you don’t know what I was crapping up there, pray hard that you don’t get this question as well.
If you know and read all what I read. Thank you! Please donate! LOL! Joking joking..

I don’t know how new is this but I just got to find out on the net that Amateur Transplants had come out with a new album!!! This is the band that I like to listen to besides all my everyday alternative rock dose. If you are a medical student, I don’t see why you don’t like this band!

The previous album Fitness To Practise had been on my Ipod playlist all the time. Those hits like Final Countdowns, Dorsal Horn Concerto and Eternal Clerking are so funny that it is almost like the brand song for med student. And of course The Drug Song as well.

Okay, now I’m going to introduce Amateur Transplants : Unfit For Practise!

It is already playing in my WMP now. Haha! The song is marvelous!!! The album consists of new and old songs at the same time. A rock version of London Underground, the infamous Anaesthetist’s Hymn.

New songs like Finals Fantasy sings about a bad student answering for his clinical exams! I’ll just quote some of the lyrics and down there is the video in Youtube.

Everybody tells me I’ll pass easily,
I’ve been working hard for so long,
But they didn’t realize my exam techniques,
guaranteeing something will go wrong….

I answer all the written papers easily,
But the clinical wouldn’t be so fine
I get so nervous I just can’t perform
Okay come in candidate 6079, tell me,

What do you see?
I don’t know..
Look at his knee..
I don’t know
What does this scar means?
I really don’t know…

All my knowledge seems to have deserted me
Let me give you this, what do you see?
This is Xray showing Crohn’s disease
No it’s not it’s called an ECG…

LOL, if you want to see all these lyrics sang out by 2 of the famous doctors from UK, you know what to do! By the way, I guess the new songs are in the Youtube as well. I don’t know, how can they sing such bad things but yet when I listen to them I’m so happy! Maybe I’m going crazy soon? Try the song ‘King of Dead’ and I bet you will laugh to death! It is only 45seconds!

This time, they are putting subjects name as their songs’ name. Songs like Psychiatry, Gynaecology, and Urology. LOL. If you don’t know what I’m talking about, look at this lyrics of the song Paediatrics-

You need a little patience,
When you trying to examine a child,
It is source of such frustration,
When you need them to keep still for a while,
They fiddle, they gargle, they giggle, they struggle, they wriggle,
No matter how many toys you give them,
They’ll cryyyyyy
God knows whyyyyyyy
You must employ cunning tactics,
when you do paediatrics,
just tryyyyyy,
when you have a little patient.

The video of paediatrics:

Love this song like shit. Haha. Enjoy!!! Sorry if I might get some of the words wrong in the lyrics because I’m doing it just by listening like this. The ‘Urology Clinic B’ is pretty fun too! See.. a fun way in studying medicine! Haha! Can’t stop laughing..

Current weather : Sunny, -10 Celsius.

Doing: Eating instant noodles, pelmeni and cutlet + red wine.

I was watching this Thai horror movie yesterday which end up with the ghost sitting on the guy’s shoulders (looking up and around). Feeling very eerie now because I’m alone at home. Errr.. Scary.

Anyway, let’s count the amount of dead bodies I saw today in the Morph. 1, 2, 3…. I think it should be 5. Yeap, this morning was my post-mortem day for my forensic medicine cycle. Besides the eerieness when I think of yesterday’s movie, I’m actually pretty happy now.

I entered the building and the first thing that welcomes me is the smell! Smell like… dead bodies. And to tell the truth, I don’t really like the idea of seeing dead people on tables and being pushed around by personnels. For one moment I thought this whole process is going to be scary, eerie and disgusting. Everybody was pretty nervous in the waiting room.

We went into the room. Today’s victim is an skinny old man who died on the street. See, I told you, lotsa people die on the street during winter. The weather is cruel. We were quite relunctant to enter the room because there are another dead auntie lying on the other table. And it took us like 5 minutes? Or maybe less and our medical students curiosity kicks in and our hands are everywhere!

It was utterly cool to have 2 experts explaining to us what is going on, where is being cut, what is seen and we have the chance to touch and see for ourselves. The lungs was bubbling when we squeeze it and the adrenal glands are so small! But I guess the smallest ever would be the hypophysis. If he didn’t even point that out, I would thought that it was just some coagulated blood. When the scalp’s skin is over the face, I think even the most timid girl in our group felt okay and didn’t actually fainted (I was expecting that). We started with checking of internal organs, and saw cardiosclerosis, ‘fresh’ infarction and normal heart muscles in his heart (the cause of death) and then to the brain, the 12 cranial nerves and revised some signs of death on the patient.

I got blood on my arms.

But luckily my white coat is clean. LOL. (meaning no need to wash).

And it lasted for some 1 hour. I was anticipating for the chance to cut things myself but well, the teachers never initiated anything of that kind and so I kept quiet. It is end of the year! I would consider ‘not cutting other people’s body’ as a good deed this year.

If you want me to summarize today’s class, well, this is a very good experience! But I have some documents to fill up, one being the crime scene report and the other one would be the autopsy report. Hate homeworks on new year holidays.

That’s all for now. 1 last day to new year!
