Transient Tachypnea of Newborn notes

Hello!

What is Transient Tachypnea of Newborn (TTN)?

Step 3 NBME Form 4 Answer key

Hey, here is the answer key.

Lemme know if I accidentally typed some wrong!

Foreign body aspiration - Flexible or rigid bronchoscopy?

Foreign body aspiration (FBA) - Which bronchoscopy should you do? Flexible or rigid?

#TLDR:
Life threatening - Rigid bronchoscopy
Diagnosis not clear - Flexible bronchoscopy

Children - Rigid bronchoscopy
Adults - Flexible bronchoscopy

Mnemonic: childRen thReatening - Rigid bronchoscopy

So first ask - is this a life threatening FBA? Yes - Rigid bronchoscopy (after airway stabilization of course)

Then ask - Is the diagnosis clear? No - Flexible bronchoscopy

If the diagnosis is clear and the FBA is not life threatening - See the age.

If it is a child - Rigid bronchoscopy
If it is an adult - Flexible bronchoscopy

Here's a looooong copy paste explanation from UpToDate:

Varenicline mnemonic

Hello!

A short post on Varenicline :)

Mirtazapine mnemonic

Hello!

Here's a short post on the atypical antidepressant, Mirtazapine! It's an alpha 2 antagonist that increases release of NE (norepinephrine) and 5-HT (serotonin)

Mirtazapine causes sedation (desirable in depressed patients with insomnia)

Mnemonic: MirtaZZZZapine
Zzz for 😴 sleep

Mirtazapine increases appetite, causes weight gain (desirable in elderly or anorexic patients)

Mnemonic:
M - Mirtazapine makes you motu
(Motu in Hindi / Urdu is fat)

Tuberculosis: Eponymous pathologies picmonic

Hey guys!!

So TB, huh? As if the complicated diagnostic and treatment modalities aren't enough, we also have to remember some characteristic pathological entities, especially the eponymous ones like Ghon, Rancke, Assmann, Rich, Simond, Simon, Weigert, Puhl, Rasmussen and I am sure there are more. Lucky for us, we have a pimonic for this.

Thank you Subasini for this wonderful illustration! Inspired! :*

Pulmonary Embolism Picmonic

Hey guys!!

Pulmonary embolism is a diagnosis of exclusion. I am sure this illustration will help you to make a diagnosis of PE after you have ruled out the other differentials.

Thank you Subasini for this wonderful illustration! Inspired! :*

Hey guys!

This picture will help you get a visual recollection of Algrove syndrome.

Poor prognostic factors for schizophrenia mnemonic

Hello!

This is a mnemonic for some (not all) prognostic factors for schizophrenia.

Likelihood ratio mnemonic

Hello! :)

The likelihood ratio of a positive test result (LR+) is sensitivity divided by 1- specificity.

The likelihood ratio of a negative test result (LR-) is 1- sensitivity divided by specificity.

How I remember the formulae for LR+ and LR-

Mnemonic on viral structures

Hey guys!! Long time!

As the title suggests this post will help you remember the different viral structures in a way that is fun and easier.

Puerperal sepsis

PUERPERAL SEPSIS

Puerperal sepsis is any bacterial infection of the genital tract which occurs after the birth of a baby. It is usually more than 24 hours after delivery before the symptoms and signs appear.

Some of the most common bacteria are:
Streptococci
Staphylococci
Escherichia coli (E.coli)
Clostridium tetani
Clostridium welchii
Chlamydia
Gonococci

SYMPTOMS AND SIGNS 
Fever (temperature of 38°C or more)  Chills and general malaise
Lower abdominal pain
Tender uterus
Subinvolution of the uterus
Purulent, foul-smelling lochia.
Slight vaginal bleeding
Shock.

RISK FACTORS
Some women are more vulnerable to puerperal sepsis, including anaemia and/or malnourished, protracted labour, prolonged rupture of the membranes, frequent vaginal examinations, a traumatic delivery, caesarean section and retained placental fragments, PPH, diabetes all predispose to puerperal infection.

SITES
The most common site of infection in puerperal sepsis is the placental site.
Other sites of infection are abdominal and perineal wounds following surgery and lacerations of the genital tract, e.g. cervix, vagina and perineum.

Following delivery, puerperal sepsis may be localized in the perineum, vagina, cervix or uterus.
Infection of the uterus can spread rapidly if due to virulent organisms, or if the mother’s resistance is impaired.
It can extend beyond the uterus to involve the fallopian tubes and ovaries, to the pelvic cellular tissue causing parametritis , to the pelvic peritoneum, causing peritonitis , and into the blood stream causing septicaemia

DIFFERENTIAL DIAGNOSIS
Fever  in the puerperium can also be caused by:  urinary tract infection (acute pyelonephritis)  wound infection (e.g. scar of caesarean section)  mastitis or breast abscess  thrombo-embolic disorders, e.g. thrombophlebitis or deep vein thrombosis  respiratory tract infections.
