Ehler-Danlos Syndrome (EDS) - High yield only

Hi! So let's learn EDS together. I've tabled a list of high-yield points of all the types of EDS. It requires little bit of revision but once you get a pictorial familiarity you should be able to recall them all. 

Have fun!

So, how to remember?

Step 1. Divide the table into 2 halves. Sl no. 1,2,3 have in common a lot of features:

• They are all Autosomal Dominant. 
• They have common Clinical features - skin HYPERelasticity, joint HYPERmobility and HYPER (easy) bruising. 
• Go serially, Classical has the first 2, Type I and II and HYPERmobile is III and lastly Vascular is type IV 
• Vascular type has additionally - arterial & uterine rupture.

Step 2. Now the second section Sl no. 4,5,6

• EDS types with enzyme defects are Autosomal Recessive. So, 4 and 6 are AR. 
• Kyphoscoliotic EDS is Type VI (K rearranged is a V and I)
• For the last 2, mnemonic is ABCD😛 Arthrochalasia VII a, b and VII c is Dermatosparaxis.
• KyphoSCOLIOTIC EDS - defective lysyl hydroxylase (=> abnormal cross linking of collagen or KOLLAGEN => think of bones 🦴 => congenital SCOLIOSIS)
• ARTHROchalasia is COL IA (1st letter is A) and hence presents with severe JOINT hyper mobility.
• DERMATospARaxis is AR and a defective Procollagen-N-peptidase and presents with CUTIS laxa. (Cuties are Pros ;)

Step 2. For the Gene types, come down in descending order: 5 4 3 2 1 0 

Step 3. Remember Type V - DOEST NOT EXIST. 

Step 4. Revise again 😉

That's it! Stay safe 🌸

Types of COVID-19 antibody tests

Hi everyone! 

In this post, I will go over in very short the different types of  COVID-19 antibody tests.

Cancer Screening - US Preventive Services Task Force (USPSTF) guidelines

     As the saying goes - "Awareness is Power in a world where information is everywhere", lets quickly learn the USPSTF recommended guidelines for Cancer screening

CANCER	SCREENING MODALITY	AGE GROUP
Breast Cancer	Biennial Mammography	Women aged 50 to 74 yrs
Cervical Cancer	Cervical cytology every 3yrs   Cervical cytology every 3 yrs  or High risk HPV(hrHPV) testing every 5 yrs or hrHPV testing in combination with cytology every 5yrs (cotesting)	Women aged 21 to 29 yrs  Women aged 30 to 65 yrs
Lung Cancer	Annual Low dose CT chest (who have a 20 pack-year smoking history and currently smoke/quit within past 15 yrs)	Adults aged 50 to 80 yrs
Colorectal Cancer	Colonoscopy screening every 10 yrs Flexible sigmoidoscopy every 5 yrs Computed tomography colonography every 5 yrs High-sensitivity guaiac fecal occult blood test (HSgFOBT) or fecal immunochemical test (FIT) every yr Stool DNA-FIT every 1 to 3 yrs	Adults aged 45 to 75 yrs

P.S. - USPSTF now recommends screening for Colorectal cancer in adults aged 45 to 75 years

Fact of the day - Athlete's heart

Hi!

Athlete's heart - physiologic eccenteric hypertrophy (cardiac remodeling) - changes include resting bradycardia, higher cardiac output with exercise, dilatation of LV cavity size with hypertrophy of myocytes compared to normal heart.

vs pathologic hypertrophy in case of systolic heart failure, aortic/mitral regurgitation, dilated cardiomyopathy(DCM) (volume overload conditions).

LV systolic ejection fraction is normal - low-normal in athletes.

(vs HCM- high, DCM- low)

HCM is a common cause of death in athletes, especially those with family history.

METABOLIC SYNDROME - MNEMONIC

BE AWARE of THE HIGH SUGARS

(3 or more of the following : diagnosis of Metabolic syndrome)

Abdominal obesity ( waist circumference) > 40 inches in males; >35 inches in females

Triglycerides >/=150 mg/dl

HDL cholesterol < 40mg/dl in males; < 50mg/dl in females

Fasting blood Sugars >/=100mg/dl

Hope this helps:)

Fact of the day - halothane hepatotoxicity

 Hi!

A patient with biliary stones who's undergone laparoscopic cholecystectomy may develop signs of hepatotoxicity between 2 days - three weeks post-op. due to halothane. The mechanism is this anesthetic's biotransformation to reactive metabolites through P450.

At risk category of patients are females more than 40 years of age.
Labs show elevated AST and ALT.
Hepatitis is relatively rare.

Other effects:

- Cardiac arrhythmias

- malignant hyperthermia

- hypertension

Levetiracetam - pregnancy considerations

 Hi!

Levetiracetam, used primarily for seizures control, is also used off-label for SAH, status epilepticus, seizure prophylaxis in craniotomy and traumatic brain injury.

Dosing is increased in pregnancy and closely monitored regularly due to various physiologic effects, especially in third trimester. (levitate dose of levetiracetam) :-

- increased volume of distribution, Vd (increase in plasma volume, CO)

- increased renal excretion (increase in GFR; levitate the rate)

- rapid and almost complete absorption via GIT  (unlike other drugs with decreased absorption in pregnancy)

- low risk of adverse effects and fetal malformations when used in monotherapy. (low with mono, high with poly)

- Levetiracetam is NOT metabolized by liver; Cyt P450 independent. Bioavailability 100%. (unlike other antiepileptics - hepatic metabolism increases in pregnancy)

Levetiracetam crosses placenta and can be detected in the newborn. (leve leaves mother)

The newborns are at greater risk of SGA and low APGAR score.

Protein-binding of the drug is low (<10%). So, decrease in albumin concentration during pregnancy does not significantly affect the drug concentration. (low pro)
