What do these people have in common [(aside from being lovely) aside from Lady GaGa]? They have the numbers, numbers that have gone over the top of average people. These single ladies have climbed up the pyramid to dance on a disco stick (what?). They have proven that people having more is not always negative. These multiple digits are simply the evidence of this statement.


Going back to reality, having an excess of something is not always as gracious as what those glittery singers have. Imagine a cup of coffee with 1/2 sugar, 1/4 coffee and 1/4 water... Quite a treat eh? Or taking a 500 item test in 30 minutes after a 24 hour duty. Got the picture? Another addition to this "uber" collection would be drugs.


Well, of course we all know that taking prohibited drugs is a big no no (prohibited right?). But what others aren't aware of is that there are also drugs, normally and casually taken in by others (under certain conditions), that can cause detrimental and potentially life-threatening effects if taken beyond their means. Some of these are Cardioactive drugs, Anticonvulsants, Analgesics, and Aminoglycosides.


001 - Cardioactive Drugs


These meds are those that are cardiac glycosides which are often used for the treatment of congestive heart failure, ventricular arrhythmias and fibrillation. Their action usually lies on altering the excitability of cardiac muscles through the Na, K, -ATPase pump. As cool as it may sound, it affects many organs and cell types. If taken beyond their limits, nausea, vomiting, and visual disturbances may be observed. When unattended, over dosage may lead to premature ventricular contractions, CNS depression and severe low blood pressure. Not a good idea if heart broken right? A list of the common cardioactive drugs, along with their toxic dosage levels are found below.

002 - Anticonvulsants

The buddy of people who experience epilepsy, convulsions and seizures. Their mechanism is quite complex, leading to its poor definition. However, its general use is the alteration of nerve impulse transmission to minimize contractions. These medicines are to be taken with caution as they may cause drowsiness, fatigue, depression and reduced mental capacity if taken at high doses. Reports of severe toxicity include pancreatitis, weight gain, and the trigger of greater seizures. Bothered? Here's a list of the drugs under this category and their toxic doses.

003 - Analgesics

Probably one of the most used drug in the world. Being mild pain relievers, analgesics seem to be the popular and affordable choice. Little did we know that it poses numerous threats when taken extensively such as:

- tinnitus (ringing in the ears)

- deafness

- liver damage

- GI bleeding

- impaired renal function

- increased heart rate and cardiac rhythm

Drugs of this category are as follows:

004 - Aminoglycosides

Lastly, the "germ" busters, aminoglycosides, are those that are frequently used in the treatment of infections with gram negative bacteria that are resistant to less toxic antibiotics. Its action lies on the inhibition of bacterial protein synthesis. The said busters are, however, busted when taken too much as they cause both nephropathy and ototoxicity. High doses may cause impairment on the proximal tubules of the kidney and disruption of the inner ear cochlear and vestibular membranes which result in hearing and balance impairment. Caution in taking them, here's a quick list:

...


Tsk, numbers really give me the headaches, maybe I should take analgesics..


...


Or not..


...


Well, it's ok, long as I take it on its therapeutic dosage..


...


Finally signing off! = }

Diary of a Fighter

February 2008

Me: What happened?

Her: A straightforward question eh? Hmm.. It was night time and I was ready to go to bed. But then I felt a slight stinging pain in my upper left chest. Being paranoid..

Me: As always..

Her: "Balamu ika ali neh.."

Me: OK, please continue.

Her: So I started to panic. But then again, my husband lulled me to sleep. How sweet of him don't you agree?

Me: Of course he is. So, how did you discover IT?

Her: Well, I was simply dressing up for an oh-so-busy yet very ordinary day. Then, as I appreciate my super sexy bod, I remembered to check something.

Me: What exactly is that "something"?

Her: My lovely lady lumps!

Me: Check it out!

Her: Excuse me?

Me: Ahem.. Sorry, please continue.

Her: I did a self breast examination on the spot. Cupped them lumps.. And found.. IT.

Me: Exactly what is IT?

Her: IT is another "lump" in my lump.

Me: Oh.. I understand. So how did you feel?

Her: Terrified of course. I immediately consulted a doctor the next day. It was as though my dreams shattered, as though I was in a telenovela.

Me: And the result was?

Her: How dry could you get? Anyway, it was benign. They found a cyst but it was benign. I was grateful about that. But little did I know that there was something BIGGER coming.

October 2008

Me: How are you?

Her: I'm better than ever. EXCEPT the fact that I'm a LITTLE unwell. I know, right now you can't tell.

Me: "Oyta magsolo keng pamagkanta." How come? What happened?

Her: Remember the time when I had an extra lump? I was under observation since then. Then IT came. Again.

Me: Again? What is IT this time?

Her: The cyst. And this time, it was back. Back for more.

     She then narrated her own version of "Series of Unfortunate Events". As she was examined, the doctors found out that the cyst (the one last February) has metastasized to a full-fledged malignant tumor -- something that every woman dread of. Right there and then, she was operated for a mastectomy of the left breast. After a biopsy, it was found to be at its second stage. Depressed as she already was, she never gave up. Never did I see a trace of fear. A brave woman indeed. Her doctor then suggested that she be subjected to chemotherapy.

November 2008

Her: And your back.
Me: Aren't you happy about it?
Her: Maybe.
Me: So what will happen now?
Her: Honestly, I don't know. But they said it's my first chemo session today.
Me: I see, today's the big day.
Her: Yup, and there will be 5 other "big days" to come.
Doctor: Oh hi there, are you ready?
Me: No.
Her: Probably.
Me: ... See you later then.
Her: Ok.


Dry conversations.. Still figuring out the "drug" for that..


     Her doctor explained that she might be experiencing some of the side effects of the main drug that is to be administered to her: DOCETAXEL. Commercially available as Taxotere, Docetaxel is an anti-neoplastic drug specially used for chemotherapy. It is an intravenously administered drug which is commonly used for the treatment of breast cancer and other cancers such as non-small cell lung cancer, advanced stomach cancer, head and neck cancer, and metastatic prostate cancer.


     Whenever she was asked as to how she felt during and after the therapy, she would briefly answer "ok mu" (I'm fine). But as she grants me with an "exclusive" interview, here is what she said:


Me: So, how did it go?
Her: It was as if something was burning inside of me, my veins to be specific. I felt nauseous after a few hours and a general feeling of weakness after a few days. It was also quite weird that I seem to have diarrhea when in fact I was very picky as to what I eat. Unfortunately, my hair is starting to fall off. But  it's good that I do not vomit unlike other patients.
Me: It's for your own good I suppose. But wait, I have been wondering why I have to wear a surgical mask. And also, why are you so isolated and confined in this room.?
Her: Thought you'd never ask. Well, they said that I'm prone to infection. That part isn't quite clear yet. But let me ask on my next therapy.

December 2008

     It was her second session. She had to be checked for her blood cells count first before undergoing the treatment. It was at this time that everything made sense. She has a very low WBC count and a relatively low RBC count. Through research, I found out that Docetaxel, a plant alkaloid, is cell-cycle specific. This means that it halts cell division of rapidly dividing cells. Cancer cells, being cells that divide at a fast rate, are killed as their RNAs or DNAs are damaged by the drug. However, chemotherapy does not know the difference between normal and cancerous cells. This is the exact reason why she has low blood cell counts and gradual hair loss.


     It was not safe for her to undergo the therapy while having low white blood cell count as it may affect her marrow. So the doctor had to administer a new drug to help. It was PEGFILGRASTIM, a long-acting form of G-CSF or granulocyte colony-stimulating factor. Administered subcutaneously, this drugs stimulate the growth of WBCs.


     Amidst the pain and numbness after the injection of the new drug, she still underwent another chemotherapy session. This went on every after 21 days. Though scarred physically and emotionally, never did I see her cry.. ...  Well, only once I suppose, but that's an extremely exclusive scoop.

April 2009

Me: It's graduation day isn't it.
Her: Yes, but strictly speaking, no. It takes at least 5 years of non-recurrence to be declared a survivor. Plus, I have to undergo radiation therapy for 2 months and take a certain MEDICATION for 2 years.
Me: You're almost there.
Her: I know.


...


Me: Phew! Makabalangingi neh?
Her: Wapin.. Ot nanan mu neh naman yan?
Me: Ala mu, trip trip.. Blogging blogging..
Her: O basta neh, Caramel Macchiato ku..
Me: Haha, opu..

Thank You..

The Rally of the Big "T"

Disclaimer: Everything in this post is factual, except for the parts that aren't..

www.flickr.com

Nowadays, students are becoming more aggressive. They seem to complain about almost everything. Sometimes, I even see students rioting in a rally, shouting, walking with vulgar banners, and sometimes even naked. It kept me bothered as to why some would do this (I actually thought of things like that myself). I thought students are supposed to be educated individuals? Shouldn't they at least act more decent? These questions kept rumbling in my mind as I drink my ever favorite *mocha frappe venti at my equally favorite "tambayan". After seconds of discerning (well, that was all it took for me to think), I suddenly realized why some students acted that way. Surprisingly, I feel for them. Maybe (a theory of my own), it was because of the severely disliked, highly over rated ordeals that every student must face. Those sleepless nights keep you groggy for the day and the pimple marks keep the girls away (OUCH!). It's those 8x11 (or sometimes 8x13) menace that crack our minds as if we needed exorcism. Do you know what it is? It's a 5 letter word which can be spelled as I-N-S-A-N-E.

T E S T S


OK, so much for an introduction (haha!). Now to the serious part. No matter how morbid my conception about tests is, there are still some (very few if I might add, hehe..) that prove to be beneficial to everyone. Let me give you 2 ironies that could help in discussing this.


IRONY #1: TESTS could help your STRESS.


By this time, you should have read my previous post so as to catch up. Cortisols, being produced upon stimulation of the adrenocorticotropic hormone (ACTH) is increased in times when we get stressed. Abnormally high and low values of these are detrimental to an individual.


If your doctor suspects high levels of these in your body, he may ask you to take a TEST. Worry not, 'cause this isn't as stressful as taking your CLINICAL CHEMISTRY MAJOR EXAM. First, you are asked to take the cortisol enzyme test which is usually verified through Radioimmunoassay (clickable link #1, hehe..). The specimen is usually blood (serum or plasma) drawn at 8am and 4pm, (for marked cortisol increase) and a single 8am specimen (for marked decrease). If you're results are unsatisfactory, then the doctor would advise you to proceed with either of these 2 tests:

1. Dexamethasone Suppression (if marked increase)

In here, you are given an oral synthetic glucocorticoid (dexamethasone) which suppresses ACTH production. Usually, if the cortisol production would decrease after this, the problem lies on the pituitary gland. (clickable link #2)

2. ACTH stimulation (if marked drop)

You are injected with synthetic ACTH in this test. If your cortisol level will rise, then it means your passed (normal).

Every test has its passing grade (so much for those demanding quotas). For this test, the passing rates are:
8am-noon: 138-690 nmol/L
8pm-8am: 0-276 nmol/L


If you're interested in applying for this test, know the details here (clickable link #3).


IRONY #2: TESTS could tell if you're DRAINED.


Aldosterones are hormones which greatly affect hydration. For testing this hormone, there are certain instructions to be followed (like those mind twisting instructions before tests). You will be advised to lie down or sit in an upright position for 15-30 minutes prior to blood collection. Oh! And also you are not allowed to intake licorice for at least 2 weeks before the test (this may falsely decrease the hormone). Then, plasma (or serum) is prepared and subjected to RIA too.


Passing scores:
for lying: 55-250 pmo/L
for upright: 2-5x the value of the lying


For a the details of the test, check this out.

Phew (again)! Too much testing really gives me headaches. Well, at least now we could think twice as to whether we should rally to the streets when we hear the word TEST. Hope you enjoyed! = }

Adrenal Cortex and its Hormones

www.andreadams.com

Mr. Bishop, a 43 year old ace blogger, has type 2 Diabetes Mellitus and frequent high blood pressure. He woke up one day noticing purplish pink - colored stretch marks on his abdomen, thighs and buttock. Also, he was easily bruised but hard to heal. Alarmed, he visited his physician immediately. The physician later noticed Mr. Bishop's high cortisol levels. He was then subjected to further testing.


...


OK, so we started off on a serious note. Well, I'm not going to bombard you with jargons and leave you totally clueless of what's going on. Let's keep it simple. By the bye, keep note of Mr. Bishop, his condition will help in our synthesis later.


In the case mentioned earlier, Mr. Bishop was said to have high cortisol levels. In situations such as these, answering point blank won't do. As a soon-to-be medical practitioner, it would be more comprehensible to follow the detailed approach and discover everything systematically. First stop: the creator.

www. kmle.com/sear.ph

As corny as it may sound, the "creator" of cortisols is the adrenal gland. Simply put, it is the ADrenal, meaning near the renal glands. Retroperitoneally located, this "2-piece" gland is pyramidal in shape weighing 4 grams each and 2 inches in length. Surrounded by renal fascia and adipose, the suprarenal gland (its name in other literature) is.. um.. well.. an endocrine gland (what did you expect?). A little history, these glands were recognized at the late 16th century. But it was not until 1805 that a certain Cuvier geek divided the glands into 2 portions: the medulla (inner) and the cortex (outer).


Having said all these, we're not there yet. Well, technically speaking, the 2 portions of the adrenal gland produce separate set of hormones. Since cortisol is the main character in our CSI-like journey, let's focus on the cortex. It is after all the bakery baking the pie.


The adrenal cortex cells exude an array of hormones using cholesterol as its raw material. These hormones, a.k.a., corticosteroid hormones, are produced in 3 regions: zona glomerulosa (outer), zona fasciculata (middle) and zona reticularis (inner). Their cells are jam-packed with lipid droplets (housing cholesterol) used for making the hormones. Microscopic as they are, each zone produces specific hormones, somewhat like a department store. For the Glomerulosa department, mineralocorticoids such as aldosterone are "manufactured". On the other hand, Fasciculata department is responsible for supplying glucocorticoids such as cortisols. And lastly, the Reticularis department produces partly some cortisol and androgens such as androstenedione and the ever famous testosterone (though only in minute amounts).

www.biocrawler.com

Wait, something's still left trivial.. What are mineralocorticoids, glucocorticoids and androgens? Maybe Ma'am Ghie will discuss it to you..


...


Or not.. it is my assignment after all..


Glucocorticoids, as the name suggests, are hormones chiefly responsible for stimulating gluconeogenesis in the liver. Also, it has other roles such as stimulation of fat breakdown, amino acid mobilization from the extrahepatic tissues and glucose uptake inhibition in muscle and adipose tissues. The main glucocorticoid is cortisol (Alas!) comprising 95% of glucocorticoid activity. Otherwise known as the "stress hormone" (since it is elevated in stress), cortisol is responsible for the immobilization of free fatty acids and spare glucose for the brain. Furthermore, it regulates blood pressure, cariovascular function, and the body's protein, carbs, and fat usage. Quite handy a hormone if I might add. Hydration helps control cortisol levels. A quick tip: hydrate more in in the middle of a stressful day.


OK! Now we're done.. or not.. again.. Since i already made mention of the different "departments", might as well discuss them, right? Right! SO, mineralocorticoids were first observed in their involvement in sodium retention - a mineral. The major mineralocorticoid is aldosterone which is responsible for Na, K, and water homeostasis. It helps in increasing resorption of water and sodium and increased renal excretion of potassium. Very handy in controlling hydration.


The last is androgens. Androgens are not primarily secreted by the adrenal glands. However, they aid in the production, but only in minimal amounts. The adrenal androgens famous are dehydroepiandrosterone (DHEA) and androstenedione. So much for the so-called male hormones.


OK (again)! Now back to Mr. Bishop's case. His signs and sypmtoms would most probably be diagnosed to a Cushing's Syndrome. This condition is otherwise known as hypercortisolism due to a marked increase in cortisol levels. The next plan of action may be to check for tumors (adenoma) in the pituitary gland. Its presence cause increased production of adrenocorticotropic hormone (ACTH) which will then eventually elevate cortisol levels.


Phew! That was close (not to mention my submission is hanging by a thread)! Hope it would help much to your knowledge and understanding. Thanks! = }

Endocrinology, Toxicology, Drug Test

Endocrinology

- this refers to the study of the endocrine gland (a gland directly responsible for the manufacturing and releasing of hormones; this includes the pituitary, thyroid, parathyroid and adrenal glands, the ovary and the testis, the placenta, and part of the pancreas) and the substances they secrete which includes the different kinds of hormones (functions as chemical messengers in the body) such as testosterone, androgens, insulin, glucagon, and more.

Toxicology

- a body of science which studies poisonous materials (toxins) and their deleterious effects upon living organisms including diseases.

Drug testing

- a system of both screening and identification of drug components in a given substance (such as urine) through a single or a series of tests.
