Fallopian tube facts and mnemonics

Hello! I read some facts about the fallopian tube so I'll be sharing it with you today!

What part of the fallopian tube does fertilization occur?
Ampulla of the fallopian tube is the most common site for fertilization.

Sometimes, the embryo isn't transported to the uterus by the cilia, causing ectopic pregnancy. This is why, ampulla of the fallopian tube is the most common site of ectopic pregnancy.

How do I remember this? Mnemonic!
FAME
Fertilization
AMpulla
Ectopic

Another random fact to remember is, isthmus is most common site of rupture of ectopic pregnancies because it is inflexible and has a thick muscularis.

Mnemonic: ISTHMUS
Inflexible
Stiff
THick
MUScularis

That's all!

Congenital cytomegalovirus infection




What I talk about in this video -

1.  CMV infection in neonates:
Signs and symptoms may include neurologic deficits (eg, seizures, chorioretinitis, hypotonia, hearing loss, microcephaly, and intracranial calcifications) as well as hematologic abnormalities (eg, petechiae, thrombocytopenia, and evidence of liver disease as manifested by jaundice, transaminitis, hyperbilirubinemia, and hepatosplenomegaly). Infants may also show evidence of growth restriction and failure to thrive. Of CMV-infected children who are asymptomatic at birth, 8% to 15% will develop hearing loss and psychomotor delay later in life

2. Mnemonic:

Remembering Apgar scoring.

Hello awesomites, finding it difficult to remember the components of Apgar score? Well, I think grouping them makes it easy-

1. The heart and lungs lie close hence,  you can group 'heart rate' and 'respiratory effort' together.

2. Reflexes are carried out none other than muscles, hence 'muscle tone' and 'reflex irritability' or 'reflex response' go into the second group.

3. Color, now it is easy to remember.

That's all!

Study group discussion: CPS 1 and CPS 2

Today's discussion is about Carbamoyl Phosphate Synthetase!

What are differences between CPS 1 and CPS 2?

CPS 1 works in the urea cycle.
CPS 2 in pyramidine synthesis.

CPS 1 is mitochondrial.
CPS 2 is cytosolic.

(Medicowesome mnemonic: Two is cys-two-lic)

The source of nitrogen for CPS 1 is ammonia.
For CPS 2, it is the amide group of glutamine.

N acetyl glutamate is activator for CPS 1.
ATP is activator for CPS 2.

Woah that's a lot of points I didn't know about!

Study group discussion: Leucine, tryptophan and niacin

Which essential amino acid interferes with the conversion of which another essential amino acid into niacin?

Leucine.

In shorghum or jowar, high leucine content inhibits conversion of tryptophan into niacin active form.

Any one knows the mechanism?

Because it inhibits quinolinate phopshoribosyl transferase.

Estrogen and osteoporosis

Lack of estrogen causes a decrease in osteoprotegerin.

Osteoprotegerin (OPG), also known as osteoclastogenesis inhibitory factor (OCIF), is a cytokine and a member of the tumor necrosis factor (TNF) receptor superfamily.

Osteoprotegerin inhibits the differentiation of macrophages into osteoclasts and also regulates the resorption of osteoclasts.
Mnemonic: Osteoprotegerin protects bone (By preventing macrophage differentiation into osteoclasts.)

Osteoprotegerin, a RANK homolog, works by binding to the RANK-ligand on Osteoblast/Stromal cells, thus blocking the RANK-RANK lingand interaction between Osteoblast/Stromal cells and Osteoclast precursors. This has the effect of inhibiting the differentiation of the Osteoclast Precursor into a mature Osteoclast.
Mnemonic: Osteoprotegerin ranks high in protecting bones.

So, estrogen kinda inhibits the osteoclasts which causes osteoporosis is the moral of the story?

Yep.

Extra: Recombinant human osteoprotegerin specifically acts on bone, increasing bone mineral density and bone volume. Osteoprotegerin has been used experimentally to decrease bone resorption in women with postmenopausal osteoporosis and in patients with lytic bone metastases.

That's all!

Submissions: Chagas disease notes

Here are some beautifully presented points on Chagas disease written by Jolhf Mathai Koshy.

I didn't know about Romanas sign and Chagomas.

The MEGA mnemonic for cardiomegaly, splenomegaly, megaeosophagus and megacolon is brilliant.

Now, my brain is swollen up with sweet information! Thanks a lot, Jolhf!

Review - How do KW lesions, disease and syndrome differ from each other?

KW syndrome is nephrotic syndrome developing due to the lesions.

KW disease refers to any other manifestations occurring due to the lesions.

Any other manifestations like?

Manifestations of glomerulonephropathy. I guess hematuria, anasarca, uremia and others.
