How to differentiate between Lateral Pontine Syndrome vs Lateral Medullary Syndrome.
What is lateral medullary syndrome?
Neurological symptoms due to injury to lateral part of the medulla. Also called Wallenberg’s syndrome.

 When does it happen?

When the posterior inferior cerebellar artery (PICA) is occluded.

What is lateral pontine syndrome?
Neurological symptoms due to injury to lateral part of the pons.

When does it happen?

When the anterior inferior cerebellar (AICA)  artery is occluded.

What do both the lesions have in common?
 Ipsilateral horner’s syndrome.
Why? Descending hypothalamic tracts affected.
Contralateral loss of pain and temperature.
Why? Lateral spinothalamic tract affected.
Ipsilateral cerebellar ataxia.
Why? Cerebellar peduncles affected. (Inferior cerebellar peduncle in medullary and middle cerebellar peduncle in pons.
Nausea, nystagmus, vertigo, vomiting.
Why? Vestibular nuclei involved.
Ipsilateral loss of pain and temperature sensation from the face (facial hemianesthesia).
Why? Spinal trigeminal nucleus and tract involved.
Ipsilateral hearing loss.
Why? Cochlear nuclei and intraxial nerve fibers involved.

So how do I tell the difference between the two?
 Lateral medullary syndrome:
 Dysphagia, dysarthria, dysphonia
Why? Nucleus ambiguous involved.

Lateral pontine syndrome:
 Ipsilateral paralysis of the upper and lower face (lower motor neuron lesion).
Ipsilateral loss of lacrimation and reduced salivation.
Ipsilateral loss of taste from the anterior two-thirds of the tongue.
Hyperacusis.




Why? Facial nucleus and facial nerve involved.

As a doctor and a humanitarian I feel it is important to cover this conflict on this blog. I think this video made by a large group of Jews who want to shed light on the subject does this succinctly and reminds us that this isn’t Muslims vs Jews but odious politics forming a black hole in the Middle East that must be purged. The above video is just the facts and the only opinion you will see is the following:

This loss of life is beyond barbaric.

Hey World: WAKE UP!

Arachnodactyly (“spider fingers”) or achromachia, is a condition in which the fingers are abnormally long and slender in comparison to the palm of the hand. It can be present at birth or develop in later life.
It is also seen in some cases that all or a few fingers can be bent backwards of 180 degrees.

homo-medicus:


There is anterior dislocation of the lens. Rupture of the zonular fibers may result from ocular trauma or other conditions. The patient underwent surgical extraction of the dislocated lens, anterior vitrectomy, and implantation of an iris-fixated intraocular lens.

radiologysigns:

A Codman triangle is a type of periosteal reaction seen with aggressive bone lesions. Due to rapid growth of the lesion, only the edge of the raised periosteum has time to ossify creating the triangular appearance. It is seen particularly with osteosarcoma and Ewing sarcoma but can be seen with other aggressive lesions too. This was an osteosarcoma.

What is visual agnosia?

 It’s an impairment in recognition of visually presented objects. It is not due to a deficit in vision, language, memory, or low intellect

Two hearts

A 64-year-old had a heart transplant due to heart failure. Because of the presence of severely high blood pressure in the lung circulation (pulmonary hypertension), the recipient’s native heart (N) was left in place and the donor heart was implanted in the right chest. The native heart maintains right circulation in spite of chronic pulmonary hypertension, while the donor heart (D) functions as a biologic left ventricle.

The post-transplantation electrocardiogram shows two QRS complexes (Panel A). The donor heart can be seen clearly in the right chest on both the x-ray (Panel B) and the CT-scan (Panel C) of the chest.

An automatic implantable cardiac defibrillator and cardiac medications are used to treat the recipient’s native heart, as are immunosuppressive medications for the donor heart.

Faggot cell is a term used for cells normally found in the Hypergranular form of Acute Promyelocytic Leukemia (FAB - M3). This term is applied to these Promyelocytes (not blast cells) because of the presence of numerous Auer rods in the cytoplasm.Promyelocytes in Hypergranular form of Acute Promyelocytic Leukemia with abundant Auer Rods in cytoplasm.
