Corona virus

Corona virus:
A) Virology:
1) Coronaviruses are classified as a family within the Nidovirales order, viruses that replicate using a nested set of mRNAs. The coronavirus subfamily is further classified into four genera: alpha, beta, gamma, and delta coronaviruses. 
2) Positive mRNA strand virus. It is largest known RNA strand.

B) Routes of transmission — Respiratory coronaviruses probably spread in a fashion similar to that of rhinoviruses, via direct contact with infected secretions or large aerosol droplets. Immunity develops soon after infection but wanes gradually over time.

C) Clinical Manifestation:
Characterized by
1) Upper respiratory tract infections
2) Acute otitis media
3) Pneumonia
4) Temporarily linked to asthma attacks in both adults and children
5) The idea that coronaviruses produce diarrhea in humans is intriguing because of their clear intestinal pathogenicity in animals
6) Gastrointestinal manifestations -diarrhea, vomiting, nausea, and abdominal pain.
7) There is one reported case of encephalitis due to corona virus
8)Also seen in association with Kawasaki disease.

D) Diagnosis:
Until recently, no sensitive, rapid method existed to detect all of the known human coronavirus strains. Rapid techniques that can be used to detect coronaviruses from nasopharyngeal samples include reverse-transcriptase polymerase chain reaction (RT-PCR) and immunofluorescence antigen detection assays.

E) Treatment:
1) There is currently no treatment recommended for coronavirus infections except for supportive care as needed
2) Chloroquine has shown some activity against cultured cells.

F)Prevention:
1) Preventive measures are the same as for rhinovirus infections, which consist of handwashing and the careful disposal of materials infected with nasal secretions. Several antiseptic/disinfectant solutions used commonly in hospitals and households, including chloroxylenol, benzalkonium chloride, and cetrimide/chlorhexidine, have been shown to be ineffective against coronaviruses

That's it!

Advice to young doctors

It is okay to disagree with another physician and acknowledge differences in the style of practicing medicine. Medicine is not black and white. Develop your own preferences based on evidence and experience.

A truly experienced physician understands the intricacies of medicine and will not criticize another physician for a decision they made under a different clinical circumstance with the information they had available.

A physician who second guesses themselves and critically analyzes their decisions retrospectively and prospectively are better than those who are over-confident about their diagnosis and management. Think about the decisions you make.

If you ever come across a bad patient outcome, yourself or your colleagues, do not jump to conclusions. There may be other factors, that you do not have knowledge of, which may have played a role.

When feedback is given, don't take it personally. Learn from the experience objectively and detach yourself from it. This way, you will learn more instead of getting offended and defensive about it.

To not get emotionally involved takes time. Give yourself time. Change the voice of the conversation in your head.

I am still learning.

Sincerely,
A young doctor.

Facebook: Wolffian duct

Q1) Ejaculatory duct in males develops from 

A) Ureteric bud

B) Mesonephric duct

C) Wolffian duct

D) Paramesonephric duct

#Medicowesome

#Gynaecology

Answer to this question is Option C) Wolffian duct.

But isn't Wolffian duct also called as Mesonephric duct ? So can you pick option B instead of option C?

Well, unless your exam allows multiple answers to be correct, do not pick 'Mesonephric duct'. Here is why?

The mesonephros gives mesonephric duct which opens in the Urogenital Sinus and forms trigone of the bladder. Mesonephric duct also gives ureteric bud to the Metanephros to form Renal system.

Now after this has happened, the Mesonephric duct will be called as Wolffian Duct which forms the internal genital organs and in females, disappears.

That's it!

Mnemonic for head posture in A-V pattern squints

Chin up in what? Chin down in what? The vexing never ends. Well, as it turns out, the word 'vex' itself is here to save the day.

Chin up- V exotropia (VEx). Remember that squint is very 'vexing'. So you stare in the sky to remember at least a fraction of what you stuffed in your brain the day before. 

Other will be A esotropia. By exclusion, it's easy to remember. 

Chin down- V esotropia or A exotropia. Again, by exclusion, these get placed naturally under this heading.

So, just remember 'VEX' and you won't be vexed anymore!

Mnemonic for Drug induced Cardiomyopathy

Hello everyone ....

Aunty is cycling 🚴‍♀️ on paved trails to protect her heart 💓 

Aunty = Anthracycline = Doxorubicin, Daunorubicin , Mitoxantrone 

Cycling = Cyclophosphamide 

paVEd = VEGF Inhibitors = Bevacizumab 

Trails = Trastuzumab

Facebook: PFT-1

Q1) Which of the following is/are not a contraindications of performing PFT(Pulmonary function test)? 

A) MI within one year

B) Unstable angina

C) Recent thoraco-abdominal surgery

D) Recent ophthalmic surgery

E) Past history of pneumothorax

So correct options are - A and E

Following are contraindications to perform pulmonary function test. 

Mnemonic: UR IRcTC

U- Unstable angina

R- Recent thoracoabdominal surgery

I- Myocardial infarction within the last month

R- Recent ophthalmic surgery

T- Thoracic or abdominal surgery 

C- Current pneumothorax

That's it!

Parasitic infections and Asthma

In parasitic infection, polyclonal IgE produced by body occupies the receptor produced by mast cells. This leads to decrease action of specific IgE required for asthma. 

This mechanism is probably the cause of decrease prevalence of asthma in tropical population.

Choristomas Vs Hamartomas

I get super confused with both the following terms, so I made a lame technique to remember both of them. 

Choristomas:

It sounds more like a Christmas. So Christmas tree is usually not grown in India but we do keep it as a sign of Christmas. 

So Christmas tree is normal, but the site (India or any other habitat) is not the usual site of tree, so let's say abnormal. 

So Choristomas is normal tissue at abnormal anatomical sites.

Example - Normal pancreatic cells under the small bowel mucosa.

They are not considered as neoplasm.

Hamartomas:w

'Hamara' in Hindi means 'mine'. 

Remember: this place is mine. So here, place is normal and tissue is abnormal!

That is, abnormal tissue at normal anatomical sites.

Example - Lung hamartomas exhibit cartilage, bronchi, and blood vessels. 

They are considered as neoplasm.

That's it!

Ocular Alzheimer's disease

A paper published in 2003 has dubbed glaucoma as 'ocular Alzheimer's disease' because some of the pathophysiological elements are similar.

Cataract in Rubella- interesting fact

The progressive nuclear cataract in Rubella may harbor live virus particles.

Psychiatry MCQ-1

So here are two multiple choice questions, whose answer changes with options. 

Q1)Most common psychiatric disorder is :-

A) Anxiety

B) Depression

C) Phobia

D) Schizophrenia

Here answer is A) Anxiety

Most common psychiatric disorder is 

A) General Anxiety disorder

B) Panic anxiety disorder 

C) Phobia anxiety disorder 

D) Depression

Here answer is D) Depression. 

Reason for such variation is that Anxiety is not just a single disease like depression.

Infact it is group of disorders. 

So Depression is the single most common psychiatric disease whereas Anxiety is the most common psychiatric disease. 

GANGLION (Last minute revision)

Spherocytosis

Hello Awesomites !

The future blogs will be on confusers.

Q. On peripheral blood smears there is presence of spherocytes. What are the differentials and the test to identify the same?

Most of you have prompted it as hereditary spherocytosis.
 Let see.

Ans. DIFFERENTIALS :- 

• HEREDITARY SPHEROCYTOSIS
• AUTO-IMMUNE HEMOLYTIC ANEMIA

 Best next step is to do DIRECT COOMBS TEST to rule out autoimmune hemolytic anemia.
For hereditary spherocytosis go for osmotic fragility test.  


 So spherocytosis doesn't means Hereditary, it could be acquired, usually preceded by an infection.

Integrating Trendelenburg

This blog will compel all the signs /symptoms Or test related to 'Trendelenburg'. Let us know if you know more of the 'Trendelenburg' in the comment section so we can integrate it here. 

Trendelenburg's gait: 

A child with unilateral dislocation of hip lurches on the affected side while bearing weight on it. Seen in DDH, poliomyelitis, Superior Gluteal nerve palsy.
Trendelenburg's gait is also known as Abductor gait or lurching gait.

Trendelenburg's test:

Trendelenburg's surgery/procedure:
It is done in GSV and SFJ incompetence. Here flush ligation of SFJ is done. Flush ligation means vein is ligated as close as possible.
Six tributaries also need to be ligated to reduce recurrence rate.
Laterally: Superior circumflex iliac.
                  Superior epigastric vein.
Medially: Superior external pudendal
                   Deep external pudendal
Distally: Accessory anterior saphenous vein
                Posterior medical thigh vein

Stripping is an additional surgery. Should be done till knee, not below knee to avoid Saphaneous nerve.

Brodie Trendelenburg's test: 

It is done to determine the incompetency of the sapheno-femoral valve and incompetency of the communicating vein.
In both the tests, patient is first placed in the recumbent position and his legs are raised to empty the veins. The sapheno-femoral junction is now compressed with the thumb or a torniquet can be used.
1) To check sapheno-femoral valve incompetency, patient is asked to stand up quickly and pressure is released. If varices fill quickly by a column of a blood from above, it indicates incompetency of the sapheno-femoral valve. This is called Trendelenburg test.
2) To test communicating system, pressure is not released but maintain for 1 min. Gradual filling of the veins indicates incompetency of communicating veins.

That's it
