Medical Lecture and Lessons
« on: March 15, 2009, 03:27:01 AM »
I have decided that learning, reciting, and teaching lessons on topics covered are better augmented when recording one's self. So I 've decided to post and record core lessons and share it with you guys. This way I can also listen and re-learn later on.

This thread will be a long thread, lol.

All are welcome to share questions regarding the subject matter.

This is a lecture on the Midbrain and associated structures: medulla oblongata and the pons.

I divulge deep into the structure and roles/functions.

High yield review ni. Please direct your questions to me if any.

The following is a great illustration/drawing of the motor pathway of the CNS; per se the primary motor area in the precentral gyrus.

And associated structures.

Genetics in a Medical Course is so amazing.

What I truly love about this course is the methods we are learning based on genetic therapy and genetic treatment.

Particularly, my favorite, are the variety of methods in replacing / repairing genes in gene therapy.

Let me tell you guys about it:

-Normal gene may be inserted into a non specific location (most common)
-abnormal gene can be swapped for normal gene through homologous recombination
-abnormal gene could be reparied through selective reverse mutation
-regulation (degree to which a gene is turned on or off) of particularly gene could be altered
-"Correct Copy" or "Wild Type" gene is provided or inserted into the genome
-Generally, it is not an exact replacement of the 'abnormal', disease-causing gene, but rather extra, correct copies of genes are provided to complement the loss of function

-Carrier vector must be used to (deliver) therapeutic gene to patients' gene cells
and the most common is the use of VIRUSES

-Viruses evolved a way of encapsulating and delivering their genes to human cells in pathogenic manner.
-Scientists tried to harness this ability by manipulating the viral genome to remove disease-causing genes and then insert therapeutic ones.
-Target cells (liver or lung cells) are implanted w/ vector & vector unloads its gene with material that contains therapeutic human gene into target cell.

Interesting and amazing isn't it?

The beauty of Medicine   :)

Thank you Bran, I sure love and always interested reading,watching and even learning things like this.I like reading medical books,love the reality or actually show like the  E.R not the drama but the real show in health chanel,Dr. G medical examiner,mystery diagnosis,Untold stories in the E.R,Trauma life in the E.R ,foresic files,anything that touches about human anatomy.
I even buy old medical books and just read it, sometimes memorize if bored.

Hi Raquel and others,

Sorry I was unable to update, busy ang schedule sa studies. Pero after this week, maka repost napood lagi ko ug other videos.

Salamat for the great response! Raquel, am very happy to read your response to see your understanding in medicine and medical lit. ha! if you ever want to talk about something medical related, share lang, and we can discuss. others invited, openly, of course.

Talking about genes, have you heared about gene mutations? We are exposed nowadays with strong chemicals (deo sprays, cosmetics, household detergents) and pollutions that our genes mutates causing sickness or diseases never heared before. This was the result of Charitè hospital in Berlin.
We became easily prone to cancers and tumors, although this is latent in our body most of the time, our immune system gets easily weak that it is easy for these cells to become malignant.

Yes, Manay Tess, thats very true.

What is beautiful in medicine is the progress of gene therapy. We are now, though limited in ability still, capable in inserting wild type genes into an affected individual's bone marrow, where his/her mutative genes have proliferated. The insertion of wild type genes in the bone marrow and injecting of erythorpoetics will allow the increased expression of correct wild type genes.

So as much as normal gene function can be rehabilitated/restored.

This has been beneficial in the treatment (palliatiative) of Tay Sachs, Gauchers, Niemann Picks, Influenza, Poliomyelitis, etc.

To all readers, listeners, fellow students, respected folks,


For the next couple of days I will post videos on Embryology and human development in the womb. I know that there are several Tubag Bohol members that are expectant mothers, and I thought it would be great idea to inform them the development of the child from 1st, 2nd to 3rd trimesters--till partition.

As always, all are welcome to ask questions, discuss and engage in this thread.

I am also open to making videos on request, so i just want you guys to know that. Don't be afraid to ask. In the end, it helps me out because it forces me to remember--and its review for me.

Starting next week, I will get back to posting videos on pathology, microbiology, pharmacology and behavioral psychology/psychiatry.


Yours,
Bran Lorenzo

You're so welcome, Priscilla. Anything I have learned, am always happy to share. We're all in this together. Knowledge and information is key--especially when it comes to health and medicine. Teaching and sharing people about medical conditions only increases their understanding of possible effects, conditions and consequences.

I'm happy to know that you enjoyed the videos and others as well.

Keep on watching, ill post more. Remember, im open video requests.

See ya~

So to begin the lecture on Pharmacology, I begin in explaining the treatment of Glaucoma.
What is glaucoma? it is a medical condition in which there is a blockage of the canal of schlem, leading to a blockade of Aqueous Humor of the eye.

Onto Pathology-->

So we defined, in previous videos, what cell injury is, and what causes cell injury. So one effect of cell injury is Inflammation.

This specific video I go into detail about Acute Inflammation: its causes, stimuli, symptoms and clinical features.


http://www.youtube.com/watch?v=3oUxDsZp71Y

I will be making another lecture / video on Chronic Inflammation and Treatment. Stay tuned.


Thanks.

Alzheimer's, Begone!
« Reply #26 on: May 31, 2009, 11:47:22 AM »
The drugs Rivastigmine, Tacrine and Donepezil have been proven to be effective against Alzheimer's.

The biochemistry of these drugs in their treatment of AS is the fact that they are ACHE-inhibitors. That means these 3 drugs are acetylcholine esterase inhibitors. These drugs prevent the breakdwn of acetylcholine by the enzyme acetylcholine esterase. Due to this, it leads to the retention of a high ACH concentration within the brain, due to these 3 drugs' ability to cross the Blood-brain barrier.

It has been proven, medically, that intake of these 3 drugs have led to positive results regarding the treatment of the debilitating disease known as Alzheimers.

However, there are major and significant side effects. These include:
CNS sequelae (nausea, vomitting, dizziness)
Diarrhea, abdominal pain, alteration of liver function and damage.

INTERESTING!

We, in the medical community, have found the cure for Alzheimer's. ;D
To God be The Glory!

Thank you so much Pare for sharing to us your medical knowledge through TB.  This is a kind way and very informative.
Genetically,  I am a stroke candidate. My Father died after having his 4th stroke, it was a long fight during the period of ten years.  I have my daily HB medications and undergo medical check-up every now and then.

Sigi ha, be my home Physician if you will be having your future private clinic in Valencia, okey?

Dear Pare,
Every quarter, must have to see my Eye Dr. for  "eye pressure measure"....I have a constant high rate at about 19 to 23 both eyes but got no medications yet instead have to submit every year an OKT examination - they called it "Optische Koharenz Tumographie"- to control my visual nerves (so far, it is still okey) this kind examination is quite expensive in which my medicare pays only the so called "ocular fundus  eye examination" which is yearly done too. I got only Eye drops against eye dryness.
I am taking 5 mg HB tablet and I also take 1 aspirin daily in which I think it's not bad .  But am also taking a 5 mg. hormon tabs which contradicts and  lead to have a higher eye pressure, right?
I've been planning to exchange my two cats against a guide dog as I told to my Eye Dr. ;D

I am working during nightime and using PC, expose to dust and fluorescent lights. Do you think this is one of the reason why I have this eye disorder?  My Physician just suggested...to have a successive check-up in which I really do.  Sus....unsaon nalang ug adto nako sa Bohol magpuyo.  Lisod!

I thank you Pare!

Good Evening Pare, i apologize that i was unable to respond quicker.

You have very interesting questions considering your eyes and I will try to answer your questions to the best of my knowledge.

If it is in your history that you have high blood pressure that results you to take blood pressure medications, as well as taking blood thinners--any generic brand will do: Aspirin will do well. It is necessary. As for taking estrogen pills--it is necessary--as you are taking this for your night flashes, am i I right?

In any measure, pare, the reason for your raised intraocular pressure is probably due to a blockade of  your canal of schlemm, which is preventing the drainage of the aquous humor that is located in the anterior and posterior ciliary body. This blockade can be easily treated by taking vasodilatory medications such as pirenzapine and or timolol and said generics.

Vasodilation means = Expanding and dilating the vascular blood vessels in your body--meaning you increase the canal of schlemm in your eye--therefore increases filtering and decreasing the intraocular pressure.

Additionally, vasodilatory drugs can have excellent effects for high blood patients, as it will lead to a decrease in Total Peripheral Pressure (TPR). Vasodilation will expand the blood vessels--meaning that more blood will be retourned to the heart via venous flow---therefore meaning less pressure on the heart to pump oxygenated blood. Due to the decrease in TPR, this will--naturally--lead to a decrease in BP (blood pressure). This is effective for tachychardic patients (high heart activity---too much of which will cause a Cardiac Failure: heart attack) So we are adviced to utilize this.

----

The examination that your opthalmologist or optomistrist is giving you is nothing but what we call here in the USA as COCT scan (Cranial-Optical Computed Tomography  Scan).
CT scan can better observe and analyze any blockage in blood vessels in around your craniofacial region pertaining to your eyes---to diagnose what can cause the increased pressure or any optical nerve damage.

It will be expensive, pare, as CT scans--even here int he USA is expensive. But it is excellent preventative measure---as CT scans are far more accurate than the old X-RAY methodology--which was once used 20-30 years ago.

Now, we medical students are adviced to utilize CT scans---as it is far more effective and accurate in analysis.

----

So my advice to you is to take to your physician about possible treatment for glaucoma/ either open angle form. Ask him about medications that can be used to aleviate IOP (intra-ocular-pressure).

Though I am very confident that any of the following medical drugs can alleviate your problem:

1. Beta Blockers
2. Prostaglandin analogues
3. Alpha-adrenergic types
4. Carbonic anhydrase inhibitors
5. Miotics.

Just write down these 5 possible treatment options, and give this to your ophthalmologist and he will know what to do. Good luck pare. And remember---taking and eat alot of Vitamin A. Vitamin A is helpful for the produciton of Rods, Rhodopsin and Cones in our eyes. It is necessary for good sight.




Good luck and take care. :)


Best,
Bran Lorenzo

Pare, that is very true about moving back to countries like the Philippines--and the province of Bohol---with medical facilities that are not so effective as say in Germany and the West. It is a reality that we must take into consideration.

My parents always talk about going back to Bohol and retiring there; but I always protest because considering the medical stuation and the poor health facilities in Bohol that cannot compare to the health care and medical provisions here in the United States of America. And the superb benefits that they have as medical care workers.

It is a reality that I advice them and remind them.

It is always oportune for us to remember and keep in mind, especially our medical situation and history.

Good luck with everything Pare.

All the best,
Lorenzo

Thank you so much Pare for sharing to us your medical knowledge through TB.  This is a kind way and very informative.
Genetically,  I am a stroke candidate. My Father died after having his 4th stroke, it was a long fight during the period of ten years.  I have my daily HB medications and undergo medical check-up every now and then.

Sigi ha, be my home Physician if you will be having your future private clinic in Valencia, okey?

Dear Pareng Bambi,

I am honored that you find it informative. Yes, I learned alot and would like to share some information with you guys---that is otherwise not available openly.
I hope and wish only to share with others--so that they can have a better understanding of their own medical complications, and their bodily limitations.

I am reminded everday as I enter the medical classroom, as there is a large plaque in the student auditorium that proclaims:
"You are a Physician In Training. Physician Yourself, and Physician others. You are here to serve, for the betterment of mankind and society as a whole. So Serve."

So again, I reiterate, i am here to serve. :)


A Servant,
Lorenzo

Good Evening Pare, i apologize that i was unable to respond quicker.

You have very interesting questions considering your eyes and I will try to answer your questions to the best of my knowledge.

If it is in your history that you have high blood pressure that results you to take blood pressure medications, as well as taking blood thinners--any generic brand will do: Aspirin will do well. It is necessary. As for taking estrogen pills--it is necessary--as you are taking this for your night flashes, am i I right?

In any measure, pare, the reason for your raised intraocular pressure is probably due to a blockade of  your canal of schlemm, which is preventing the drainage of the aquous humor that is located in the anterior and posterior ciliary body.

WOW!  You've got the right diagnose and my good Professor/Eye Dr. never explained to me as perfect and accurate as you did.  Thank you very much,  dear Pare.  I keep noted  all those types of possible treatment. Next consultation... I must have to get a clear diagnose.  The last time, (it is a great joint practice medical-clinic) been examined from 5 different Physicians  since from the start....All I heard:  It could be that I am a kind of person who can tolerate having a "high eye pressure". Not really something frightening as they said but I keep on searching that this kind of diagnose is 100% ground for blindness.  I underwent 2x laser theraphy (gibuslotan ahong iris man siguro to) I forgot the medical term (it lowered only up to 19 each eyes), Also morang dihay gisuksok sa ahong canal man siguro to sa mata, kana bitaw na-ay gamay kaajo nga buslot diin giingon nga mahilis ra kuno tong gisungsong. Already three times that I submitted that  one day 4x interval eye pressure measurement.  So far, it is a must to visit my Dr. 3very quarter especially that since 4 years I have an additional eye discomfort "Eyes migrane" A zic-zac lightning especially if I am exposed to sunlight. Pastilan Pare.....it is not easy getting tigolsna gjod.  The first COCT they made, the diagnose was alarming than that r second time result ... it seems that it is getting better without any medications and/or eye drops against Glaucoma.   This is the reason why I am ordered to be examined every 3 months. Basta...I feel like under studied.  And this COCT is the best way for a better diagnose and prevention as my Dr. said.
Yes, COCT is originated from US and sorry to say that the German government imposed  a restriction to  our (Health Insurance Fund) not to pay other modern way of examination for a sake of illness prevention.  Ex: An Osteoporosis  patient with a legal medicare membership can not anymore expect to receive any free receipt payment unless until it is proven that he/she has a bone fracture.  Makapungot and it is getting worser!  It seems that we are copying everything from the States. Sorry!
So much for today, I thank you for listening my physical complaints.   Hope to  hear you in my next visit in your virtual practice. God bless you and have a nice day!

Hello, Pare, yes pare I understand your situation. I am sorry lang to hear the medical situation over there in Germany is becoming more like over here in the states. That is the major problem over here, medically speaking, is that there is no universal health plan. 40 million people are not covered medically; majority of which are children and low-income families.

My personal remark on that is that we should have at least have a basic universal health care plan. Basic coverage at least. Like the one in Canada or the UK.

Sige, pare, you take care of yourself. God Bless!

To fellow medical colleagues, friends, fellow listeners, and all persons interested in this thread.

Please know that I have not forgotten about this thread. I just have been so busy with reviews. I will make a video on Anti-Hypertensive Drugs and conditions relating CCF and CHF. [Congestive cardiac failure and Chronic Heart Failure]

It will cover the following:
1. Etiology of the disease
2. Possible Drug candidates
3. Drug Mode of Action/ Mechanism of Action
4. Indications of Drugs
5. Adverse Effects of Drugs/ Side Effects


---
Due to the shear workload I am having, my constancy in video making has been limited, and am only able to go online at night or during medical breaks. So let me apologize lang if i have not posted videos for a while, please note that i have not forgotten this thread. I promise i shall make a doubly great video. hehe.

Again, I want to reiterate: If any of you have any questions, a query of a medical condition, possible drug treatments, action etc, just please jot it down and ask lang. I would love to try to answer it to the best of my limited knowledge. Or if i do not know, i will ask my medical professors and seek their advise and recommendation---and then share it in here.

All questions, all interests, are welcome here.
Remember, when it comes to medicine and health, there is no such thing as 'second choice'. It is very important.


Your Friend and Colleague,
Bran Lorenzo


PS. Keep me and my batchmates in your prayers, I ask. We need the hand and grace of God to be with us--especially in this most crucial of times. Thanks, guys.

Now remember, folks, beware of excessive intake of anti-depressants, as dose dependencies can occur. In anycase if any of you are depressants, I highly suggest SSRIs over TCAs or MAOInhibs or SNRIs.

More to come. :)

In regards to treating schizo patients, or patients with psychotic disorders, it is best to provide them with any anti-dopaminergic agonists/dopamine antagonists. Lithium salts would do well, but do watch out for extrapyramidal side effects.

I'll provide more about this in a video that will combine anti-psychotics/neuroleptic drug treatment.

Thanks for all the views, and the comments on my page. to those who messaged me on questions, I will provide more vids. I promise. :)

Dong, the SSRIs are the first-line agents for depression, not because they are more effective than the other drug classes but because they are generally safer, with fewer side effects. Most of the TCAs I see in practice right now are either used as 2nd-line agents for refractory cases, or as sleep aids. One can OD easily with TCAs though, thus the limited use in clinical practice. I almost never see anyone on MAOIs anymore. Out of the hundreds of patients on anti-depressants that I see, probably just one or two are on MAOIs. The SNRIs have pretty much the same safety profile as the SSRIs, with the added benefit of NOT causing as much weight gain as the latter. In fact, many patients lose weight on while on this med class. The last one is Wellbutrin, which acts on NE and Dopamine (and a little bit on serotonin as well), a lot of people prefer this coz it doesn't cause the sexual side effects that's typical with SSRIs. This can be used as an adjuvant also with SSRI therapy, to counteract the weight gain side effect.

Can you discuss fish oil, dong? Very promising pud siya sa depression.

God bless,

The atypical anti-psychotics are considered 1st-line these days because they cause fewer extrapyramidal side effects than the older agents. Monitor carefully lang ta ani kay ga cause ni sila metabolic syndrome and less frequently, agranulocytosis (esp. with Olanzapine).

Personally, ang akong nabantayan nga common side effect with people on anti-psychotics, dong, is tardive dyskinesia. It's barely noticeable on others, but on some people, very pronounced gyud. Mao nang usually, trial and error gyud to treat this. Most people don't do too well on monotherapy anymore.

Hello Darling Ate Ethylene,

I'm glad you found this little niche, hehehe.

Ang primary anti-epileptic strategy namo karon is to address the situation. Initial treatment to suppress or reduce the incidence of seizures is based on the specific types of seizures. Thus tonic-clonic (grand mal) seizures are treated differently than say---absence seizures (petit mal).

The use of monotherapy is initiated w/ a single agent (phenytoin, phenobarbital, ethosuximide, valproate (valproic acid or di-velproic acid), or zonisamide, or BNZ, or GABA-PENTIN. -- we administer monotherapy until seizures are controlled or or the toxic signs occur.

If seizure conditions is refractory to monotherapeutics, a second drug may be added to the therapeutic regimen.

You are right tho, 'te, monotherapy is rare nowadays due refractory effects.


hehehe, such a sharp and intelligent lady~~~


Always,
Bran

Hahaha yes yes yes! Sharp and correct jud ka oi!
Agree ko sa imung observation 110%.

;)

I will honor your request, darling Ate.
Fish oil is also good for hyperlipidemic states. It has been medical established that increased intake of fishoil has lead to the increase of HDL (high density lipoproteins), which is good for the heart (cardiothoracic health). And increase in HDL will result in a reduction of LDL (low density lipoprotein; and ldl is correlated to atherosclerotic growth --> which leads to prothrombotic states---> which can dislodge and cause systemic embolus---> can cause visceral infarct ---> if untreated via thrombolytics and anti-platelets/anticoagulants, will lead to Death.

Since HDL outcompetes LDL for the ldl receptors in the liver, this will lead to the metabolism of ldl and prevention of its development in to cholesterol states; thereby increasing the health of the patient.

HDL = very good for pt
LDL = contraindicated for pt.

Dear Ate,
I will honor your request.
Give me a few days. lang.


Love,
Always,
Bran

In some instances, Ethyl, the patient responds well with monotherapy of EPA (from Fish Oil) and has positive results for depressive patients. But a dual therapy with atypical types such as: Bupropion, or mirtazapine and also: EPA(fish oil) is proven effective.

hehehe cool stuff actually, i learned alot in this mini-research.

Ethy. I do have a question for you, I was talking to my pharmacology and Behav. Psychiatry instructors regarding this earlier today and one thing that i was observing was that some typical anti-depressant drugs have inductive capability of P-450 enzymes and also some have inhibitory effects of the P-450. So in the case of depressive patients that were taking warfarin or heparin to treat their CHD conditions or any CVD conditions as well as depressive states, this would impede the effect of the drug warfarin since it would be subject to hepatometabolism, or the antithesis in the case of inhibitors of the P-450 isoenzymes. I bet you see alot of prescriptions for patients with depressive states as well as HTN/coagability states with changes in dosage for the hemotastatic drugs.

When we treat patients with drugs of the SNRI class (ventafaxine, venlafaxine), these drugs have critical A/E such as:  GIT disturbance (n/v/d: nausea-vomitting-diarrhea) as well as CNS sequelae, and instances of insomnia and sexual dysfunction.

We are taught to treat depressive patients with: Atypical drug therapy and then typical drug therapy. However, my only concern is the fact that atypical drug therapy has substantial S/E that include: tremors, seizures.

My question to you, regarding this, is : Do you see much prescription of drugs such as Mirtazapine and Bupropion to treat anti-depressive states or more so of drugs such as: duloxetine and venlafaxine, Risperidone, Sertindole, Clozapine?



Thanks a bunch, darling.

Thanks for the post on fish oil, dong. I am getting ready for fish burps. LOL

I was intrigued by your question so I looked into our files and I was surprised actually with what I found out. We have a lot of patients on warfarin but only two were on antidepressants concomittantly. One is on prozac, the other on zoloft. Warfarin is metabolized thru CYP2C9, and prozac inhibits CYP2C9, so I was a little surprised about that. The doctor started with a really low dose though, and the warfarin dose was adjusted as well. Still, it's worrisome coz prozac has a really long half-life. Sertraline on the other hand works better w/ warfarin coz the former mostly inhibits CYP2D6 and it doesn't make that drastic of a change in PT and INR.
We don't have a lot of patients on Mirtazapine. It is not a commonly prescribed drug. That goes for nefazodone as well. Venlafaxine and Buproprion on the other hand are fast-moving drugs. Trazodone is a common prescription too, but not for depression. It's mostly used as a sleep aid. Duloxetine is popular too, for depression as well as for neuropathic pain and fibromyalgia. The SSRIs are still the most prescribed antidepressants. I believe a major factor is the price. They're really cheap, most are only $4 for a month's supply. I also think a big factor on doctor's choice of a med for a patient is what that patient's insurance would pay for. Insurance companies have a tier copay system where SSRIs have the lowest copay, then Buproprion is middle ground, Venlafaxine usually has the highest copays. A lot of companies won't pay for nefazodone or mirtazapine at all. Clozapine is very rarely dispensed, at least, in the retail setting. It is highly regulated, doctors, patients and pharmacies have to enroll and register with a national clozapine program, requiring lots of steps and paperwork, not to mention all the monitoring with bloodwork and everything. So clozapine is reserved for the really refractive cases.
As far as warfarin and antidepressants, they don't pose really severe interactions, thus they are not absolute contraindications. The doctor can prescribe any antidepressant he wants, as long as INR levels as closely monitored. But then, it also depends on what the patient is willing to pay for or what the insurance company would cover.
Hehehe, naglabad akong ulo kay nagamit nko akong utok ug gamay. I will hibernate for a while to recharge. My next post might not be for a while. Always take care, ok? Take it easy with the caffeine. mwah!

Let us proceed further to the discussion of Virology, a subset of Microbiology.

One topic that I want to share here is the concept of Pox Viridae (Pox Viruses), this is the 2nd largest viralgroup, next only to herpes viruses. It contains DNA and RNA. It is brick-shaped ; it is a double stranded DNA , which is enveloped. And there are over 10,000 viruses particles produced from each affected cell and one big particle.

So let me share some Epidemiology of Small Pox:

Pox Viridae do not cause chickenpox; chicken pox is caused by the herpes viridae varicella zoster (VZV). Do note that Pox Viridae Used to cause Small Pox.

Why do we say 'Used' to cause small pox? Answer: That last case of small pox was in 1977. Small Pox is the only major viral agent that has been eradicated from the face of the Earth.

For more than 3 thousand years this highly contagious virus spread via the respiratory tract; causing pox skin lesions and death. A concerted vaccination and surveillance program conducted by the World Health Organization brought this tyranny to an End.

Small pox was the agent that was responsible for the ERADICATION of the Native Americans in North America and Central-South America.

The Small Pox Virus has been eradicated by Medical Science.
Completely.

Catalina,

I will answer your question here.
Lupus or otherwise known as SLE (systemic lupus ereythematosus) isn't a viral or bacterial disease that can be transmitted via aerosol.

It is an immunological defecit. Its a hypersensitivity disease; Type III Hypersensitivity. It is a result of your body being unable to recognize self antigens; as a result, the body's human immune system (innate and adaptive) will target and attack the self antigens; it can lead to systemic damage.

There is no cure to this; as it is a genetic disease; a result of the antigen presenting cell's inability to recognize the 'self' antigen.

What we can do; is suppress the immune system to hinder the damage and prevent further systemic prolapse.

The adverse effect, of course, is bacterial and viral infection as a result of drug-induced immuno suppression.


If you have further questions, you can reach me vis-a-vis:
[email protected]

Hi Guys,

I recently presented a Medical Case Review on: Schizophrenia and Psychotic Disorders , the mode of treatment, diagnosis, and relations recently this month.

As a member of the AMSA (American Medical Students' Association), we, medical student members, are required and opted to present a case that has our interest.

In ever so much interest in the mode of psychotic diseases and treatment of psychotic diseases, which has been fueled by this year's Medical Pharmacology and Psychiatric Behavioral Science classes, I have grown quite interested into the diseases that have plagued human mental health and psychological disturbances.

In understanding the chemical and hormonal imbalances, the pathway deviations, and the methodology that is implemented to correct the neuropathology.

So, I presented on Schizophrenia, a disastrous and severe psychotic disorder, a result of excessive dopaminergic activity and inhibition of inhibitory pathways.

I will post some clips of my presentation; as I was recorded and filmed during my presentation. :)

I thank my friends and medical staff for the recording, as it has been quite rewarding watching it again.

I hope and trust all of you will enjoy it as well.

A learning experience pood.


All the best,
Bran Lorenzo

Blessings and Peace of Our Lord Jesus Christ be with you and your family, Manay.

Thanks for the question, manay it is very hard to care for parkinson's patients, there is great emphasis on physical exertion and emotional/mental ability, God Bless you for your love and caring of your mother in law.

If it is difficult, I would recommend you purchase a nasal feeding tube, to increase nutritional input for your mother-in-law. A decrease in appetite and refusal to eat is a hallmark of parkinsons patients. If you can, Manay, it would be beneficial if you could hire a part-time nurse to help you care for your mom-in-law.

Remember to feed your mom enough soft foods: proteins, starch, and multivitamins.
--If you can, purchase ensure for her, it is a chocolate brand of drink (comes in different flavors; it is a rich source of multi-vitamins, and high in protein and anti-oxidants).
This is what we give to my Lolo, who is himself 82 years old, and is good source of calcium, especially good for elderly patients with developing osteoarthritis and osteoperosis, and increased osteoclastic conditions (bone loss).

here is the link to ENSURE.
Im sure it is found there in Germany, its quite common in Europe.
http://abbottnutrition.com/products/products.aspx?pid=14


---

For your mama's hypertension, ask your doctor to put her on Anti-Hypertensive medication:
recommed the following:
1. ACE INHIBITORS (angiotension converting enzyme inhibitors)
 --> If your mom develops coughs when taking ACEINHIBS, then i recommend she takes: ARDS (LOSARTAN)
2. Beta Blockers
3. Calcium Channel Blockers
    ---> this works well for elderly patients over 55yo.

Thanks for asking Manay, and I do earnestly hope and pray your mama stays in good health.
An extra prayer here and there helps any medical treatment. he he he

EXTRA CARE AND EXTRA LOVE from OUR LORD JESUS CHRIST! :)

Medicine can only do so much. The power of Prayer can compliment any treatment.


Blessings and Peace,
Bran

Nigamay akong ugangan Doy, I think she shrinks. She has alert mind that´s why I buy her newspapers everyday. She can eat, and she loves rice and pancit. I always cook for her, so she gets warm meals. Ako jud ning gi-agwantahan kay she is a very loving lola, ( pero dili mi-vibes). Mao ni nga tig-simba ko kada adlaw, kay nangaliyopo ako sa Kahitas-an ang iyang pag-tabok linaw, kon itugot Niya.
Nag hubag iyang mga tiil, kay wala na nag function pag-ayo iyang kidney. Her medications includes tablets for her hypertension, kidney, heart disease, blood thinner and something for her Parkinson.
We will not bring her to a home for the aged, we will try our best that she is comfortable as much as possible.
I want to thank you from the bottom of my heart for your advices, Gob Bless.

Manay, am happy to hear that she has medications and is up to date with that.
Right now, the best thing for her is just being around family, appropriate foods, and a good quiet environment for her to be at peace in.

I admire your refusal to put her in a nursing home, Manay. Very honorable jud ka.
Am praying for you and your mama in law, that you have the continued strength to go on to care for her.

You are welcome, Manay, am always here to help in whatever way I can, though it be limited in scope.

God Bless You!

Human Physiology Lecture (Multiple Part Series)


Let's talk about Physiology. Human Physiology, to be exact.

If one asks, "What is human physiology?"

A: The very fact that we remain alive is almost beyond our control.
The human being is actually an automaton, and the fact that we are sensing, feeling, and knowledgeable beings is part of this automatic sequence of life.

First, know that the body is composed of cells; the cell is the compository makeup of tissues, organ systems. Estimated, there are over 25 trillion Erythrocytes (red blood cells) in the human body. Overall, there are over 100 Trillion cells in the human body.

I love to teach, Glacier, and more, I love to help people.

Its good to give back to those who ask questions on a certain medical problem; this way they are better informed when they visit their physicians next time, or inquire about certain drugs that their physician did not tell them about.

Medical Students are called to inform the public. Knowledge is to be shared, not hoarded.
That is my view on this.

Dear Students of Medicine,

W will further go into detail in Immunological Pathways by focusing on the different kinds of Immune-Related Diseases and Syndromes. We shall explore the different kinds of immunological conditions, the mechanisms of actions, the symptoms of these conditions, and any pharmacologic-surgical modes of treatment available.

This will be extensive, so this will take some time to work on.

All the best.

Doy Bran, I want to hear your opinion on this, I got it from my mailbox;



Subject: mixing medicines

This was sent to us from a nurse in a school district.....
thought I'd better pass it along just as an FYI.
"Motrin and Robitussin don't mix"!!!!!
Madison , age 8, passed away just a few days ago.
Please pass this on.
Doctors told her family that there have been quite a few children
Madison 's age that have died recently the same way that she did.
The only common link between them was that they were given Motrin
(ibuprofen) and Robitussin together, this caused a heart attack.
They believe this is what happened to them.
They told her to alert everyone to this.
"Do not give children both of these medicines together."
You can give them one or the other but not both.
When Madison collapsed she suffered a heart attack and they were able to
revive her but the loss of oxygen damaged her brain and she was put on
the respirator.
After this she had four strokes before she died after being taken off
the respirator. Please pass this on!!!!!!!!!

Manay, this email is nothing but a hoax. This has been circulating since 2007 and each year the names have changed. Motrin is nothing but ibuprofin and Robitussin is a cough suppressant. These two are OTC Drugs (over the counter) and do not require prescription, however, it is always advised to talk to your family practioner about mixing OTCs in case an individual is allergic or sensitive to any of these.

Motrin is a nonsteroidal anti-inflammatory drug whose main indicative use is to relieve pain and relieve inflammation. Tussin (Robitussin) is nothing but dextromethorphan ingredient whose therapeutic goal is to relieve coughing. Both drugs have undergone extensive testing under the FDA and there have been no negative effects relating to myocardial infarct due to intake of such OTC drugs.

The email does not indicate any underlying cardiac abnormality of the child that he or she might have had, which could have predisposed the child to a myocardial infarct (as there are many rare congenital cardiac defects that can lead to pediatric MI cases, albeit the fact that it is very rare) and it is too vague in its story line.

Let me tell you all what a heart attack is: A Myocardial Infarct (Heart Attack) is a necrotic development of the myocardium (the heart) due to hypoxia of the different parts of the heart due to atherosclerotic plaque developepment, which leads to the development of thrombi and cloggage of arterial vessels that supplies blood to the heart muscle. If the particular vessel is clogged enough, and supply of oxygenated blood is hampered to the heart, the heart muscles will die, and develop necrotic lesions and fibrotic bands. This is called an Infarct. A severe MI due to the coagulation of the coronary artery and the intervertebral arteries will lead to pan-necrotic damage to a large part of the heart, and thereby significantly affecting the heart's ability to perform its ability to pump blood to the systemic circulation. As a result of this complication, the heart will give in, and the patient will expire.

The development of a thrombi and the process of atherosclerosis is chronic in duration. This means that it takes a long time to develop and the heart attack is due to a long-term abuse of the particular vessel and occlusion of said vessel.

This thereby destroys the notion that the mixture of Robitussin and Motrin is the cause since these drugs have an effective dose for only 4-6 hours, meaning that it was given for an acute condition, and was give that day. The supposed child suffered a heart attack that day, and there is no physiologic-anatomic way that a thrombi and atherosclerotic plaque would develop within hours and completely cause a massive MI. It is an anti-inflammatory agent meaning that it would mitigate any migration of mast cells or basophils from releasing histamine (because an agent of motrin is histaminase--meaning it breaks down motrin from forming a complex and initiating its MOA (mechanism of action). On the contrary, this supposed child suffered from a long-time congenital cardiac defect, probably due to mitral valve stenosis , aortic stenosis, some kind of mitral valve insufficiency due to a congenital birth defect. The regurgitation of blood back to the atrium from the valves due to the stenosis could have affected the arteries and damaged the endothelial lining, causing thrombi to develop via chronic duration. Which could have caused the infarct. There are so many possible and plausible causes that could have predisposed the said child to such infarct that lead to death. Again, emphasis in pediatric congenital cardiac abnormality as the COD (cause of death) and not the OTC.

~

But to everyone who is a mother, father, or caring for a child, always ask your physician for advice before buying an OTC for use for yourself or for your child before actually using it. Take a conservative stance in regards to this.





Best,
Bran Lorenzo

And thank you for your concern, as it benefits all of us, I am sure. :)

Ang lesson ani, Manay, is that we be conservative in everything we read in mass chain emails.

Thank You, my dear.

In regards to the pulmonary system, its rather interesting in that the pulmonary vasculature, hypoxia causes vasoconstriction. In other organs, hypoxia causes vasodilation.

Cool.

The body's innate reaction, in regards to Tetralogy of Fallot:

Patients learn to squat to improve symptoms: compression of femoral arteries increases pressure, thereby decreaes the right to left shunt and directing more blood from the right ventricle to the lungs.

This is innate.

Presentation:

A 59 year old male presents to the emergency room with sudden severe and constant low back pain. Past medical history is significant for hypertension, hyperlipidemia, emphysema, coronary artery disease, stabile angina and a 25 pack year history of smoking. The patient was hospitalized for a CVA 7 years ago. Physical examination reveals a 5.8 cm pulsatile mass superior tot he umbilicus in the abdomen. T= 98.5 degrees F, BP= 150/90 mm Hg, HR = 80 bpm, and RR = 23 breaths/min.


Differential:

AAA (aortic dissection aneurysm), pyelonephritis/ nephrolithiasis, prostatitis, and pancreatitis.

Diagnosis:

Given that this pain developed suddenly and the presence of an abdominal pulsatile mass, this patient most likely has an AAA.

Lab Order:

CT scan with contrast, CT angiogram, and cardiac catheterization to be performed to assess cardiac risk and potentially revascularize the patient for operation. Surgical intervention mandated.

Support for surgical intervention:

As an aneurysm becomes larger than 5.5 cm, the risk of rupture increases exponentially; an aneurysm smaller than 5.5 cm is less likely to rupture and or to benefit ratio of surgery is less supportive. Therefore, if an AAA is smaller than 5.5 cm in diameter and asymptomatic, the patient can be followed with ultrasound or CT surveillance ever 6 months. If the aneurysm is larger than 5.5 cm in diameter and symptomatic, the patient should be taken to the operating room, the former is considered a medical emergency.

Aging , The Natural Process. A Psychoanalytic Point of View

Psychiatry Medical Report

by: A. Lorenzo Lucino Jr, Medical Intern


   Aging is a natural process of life and we all age from the day we were born to the day that we die, the body continues in this natural progression of life, which translates in changes in the physiological body as well as human psychology and function. When one regards the phenomenon that is aging, one has to take into consideration the negative and positive factors, in this case, healthy aging and unhealthy aging. Healthy aging refers to the positive factors that an individual goes through throughout retirement, and the positives in aging. This may include the practices of eating healthy, exercising actively, maintaining social relationships and a support group while one ages. Unhealthy aging is the antithesis of healthy aging, this term may regard to the negative aspects of aging attributed to bad health practices of an individual such as smoking, drinking, a lack of support group as one ages (Growing Old In A New Age, 1993).

   One has to take into consideration the natural processes of career development and how these processes plays a role in retirement, the psychological effects of people in retiring age. This is best observed in Donald Super’s Five Stages of Career Development; his career stages included the Growth stage, Exploration stage, Establishment stage, Maintenance stage and the Disengagement stage (Bjorklund and Bee, 2008). In regards to retirement , it is rather interesting that there is such a stark contrast in the male and female work schedule. Bjorklund and Bee mentions that more men work full time than women , importantly, more men maintain a constant work schedule as compared to women, who have to worry about taking maternity leave, sick leave as compared to men. Women are also more willing to work part time jobs than men, as well as the fact that women are more inclined to move in and out of full time jobs more frequently than men (Bjorklund and Bee, 2008). Despite the fact that more and more women are taking more active roles and positions in the work force, it is rather interesting to note that men are still being paid higher wages than women for doing the same work. This affects the notion of retirement and the prospect of retirement in that due to this stark difference in work schedules and contributions, could result in differences in social security payment for men and women.

   Retirement and the prospect of retirement is rather dependent on social security , which was established some 60 years ago during the post-Great Depression Years, and because of this institutionalized system, could allow some sort of reprieve for workers. It is also important to note that job satisfaction, work and personal life affects the choice in retiring from a particular profession. If a professional enjoys his profession and receives not only economic rewards, but also emotional, social and physical rewards from the job, he or she is less likely to retire from the profession when he or she is reaching retiring age, but would rather choose to work part time. As compared to an individual who had less interest in the work place and would probably take the option or retiring early (Bjorklund and Bee, 2008).

   One also has to take into consideration how marriage and family life affects work and the prospect of work. It is evidenced that married men will earn a higher income as compared to unmarried men, likewise, married men are absent from work less than unmarried men (Bjorklund and Bee, 2008). Elizabeth Gorman notes that married men and women are usually more interested and focused on the prospects of a job than single men and women (Bjorklund and Bee, 2008). One can argue that due to the fiscal responsibilities of married couples, which might include paying off a mortgage loan, ensuring that their children finish college and find a stable profession etc. All of these said fiscal responsibilities and duties might play a significant role in a couple’s decision to retire from a job, or even delay retirement definitely. One has to understand that retirement will have particular effects, including a change in income, change in insurance coverage, and thus could play a role in the decision to retire or delaying retirement for some time. A couple who is in the retirement age, have no children, paid off their financial responsibilities would be more willing to retire than say a couple in retiring age that still had children in college, still paying for mortgage and other secondary expenses.

   In regards to Bjorlund and Bee’s teaching on the effects of retirement and the notion of the feminization of poverty. However, it must say that I do agree that retirement is more possible in this epoch because of the presence of social security, retirement benefits, pensions, as well as assets that are available as compared to say some 70 years ago when an individual was expected to work till he or she died.

Hi guys. Let's talk about Renal Physiology and the clinical significance of it all. :)



CLINICAL ESTIMATION OF GFR AND CONCEPT OF CLEARANCE



GFR= Glomerular Filtration Rate
CLEARANCE = Refers to a theoretical volume of plasma from which a substance is removed over a period of time.


-Estimates of GFR are used clinically as an index of renal function and to assess the severity and course of renal disease

-A fall in GFR means the disease is progressing , whereas an increase in GFR suggests a recovery

-In many cases a fall in GFR may be the first and only clinical sign of renal dysfunction

-Estimation of GFR rely on the concept of clearance

What determines GFR?


-Except for an unusual situation when plasma protein concentration changes dramatically or renal obstruction develops, the main factor determining GFR is glomerular capillary pressure.

-An increase in capillary pressure increases GFR, and a decrease in capillary pressure decreases GFR.

Nephrotic syndrome

Nephrotic syndrome is a group of symptoms including protein in the urine (more than 3.5 grams per day), low blood protein levels, high cholesterol levels, high triglyceride levels, and swelling.

Nephrotic syndrome is caused by various disorders that damage the kidneys, particularly the basement membrane of the glomerulus. This immediately causes abnormal excretion of protein in the urine.

The most common cause in children is minimal change disease, while membranous glomerulonephritis is the most common cause in adults.

This condition can also occur as a result of infection (such as strep throat, hepatitis, or mononucleosis), use of certain drugs, cancer, genetic disorders, immune disorders, or diseases that affect multiple body systems including diabetes, systemic lupus erythematosus, multiple myeloma, and amyloidosis.

It can accompany kidney disorders such as glomerulonephritis, focal and segmental glomerulosclerosis, and mesangiocapillary glomerulonephritis.

Nephrotic syndrome can affect all age groups. In children, it is most common from age 2 to 6. This disorder occurs slightly more often in males than females.
