Murmur

Important Murmurs
Austin Flint murmur : Austin Flint murmur is
a mid-diastolic rumbling audible in subjects
with severe aortic regurgitation that is best
heard at the apex with little radiation.
Several theories have been suggested for the
origin of the murmur: (1) vibration of the
anterior mitral valve leaflet due to the
regurgitant jet, (2) collision of the jet with
mitral inflow, (3) increased mitral inflow
velocity due to narrowing of the valve orifice
by the jet, and (4) vibration from the jet
impinging on the myocardial wall. It differs
from mitral stenosis murmur in that ,it
occurs in the presence of a murmur of aortic
valve insufficiency and in the absence of the
rheumatic, mitral opening snap.
Carey Coombs murmur : Mitral valvulitis
associated with acute rheumatic fever may
cause a low-pitched mid-diastolic rumble. It
can be differentiated from the diastolic
murmur of Mitral stenosis by the absence of
(1)an opening snap, (2)presystolic
accentuation & (3)loud first heart sound.
Cruveilhier-Baumgarten murmur : Venous
hum heard in epigastric region (on
examination by stethoscope) due to collateral
connections between portal system and the
remnant of the umbilical vein in portal
hypertension.
Duroziez's murmur : Its a to & fro murmur
heard over the femoral artery during both
systole& diastole. It is elicited by applying
gradual arterial compression with the
diaphragm of the steth. This compression
not only produces systolic murmur(which is
the normal result of arterial compression) but
also a diastolic murmur(which is pathologic
& suggestive of aortic
regurgitation).Sensitivity of 58-100%.False
positives occur in high output states. In high
output states the double murmur is due to
forward flow. In Ar one murmur is due to
forward flow& the other due to reverse
flow.The two can be differnetiated by
applying pressure first on the more cephalad
edge of the diaphragm & then on its more
caudal edge. The murmur of forward flow is
enhanced by compressing the cephalad edge.
Conversely the reverese flow murmur is
enhanced by compressing the caudad edge.
Gibson murmur :The typical continuous
"machinery-like" murmur of patent ductus
arteriosus.train in tunnel murmur
Graham Steell's murmur : Due to pulmonary
regurgitation in patients with pulmonary
hypertension and mitral stenosis. It is a high
pitched early diastolic murmur heard best at
the left sternal edge in the second intercostal
space with the patient in full inspiration.
The murmur is heard due to a high velocity
regurgitant flow across the pulmonary valve;
this is usually a consequence of pulmonary
hypertension. The Graham Steell murmur is
often heard in patients with chronic cor
pulmonale as a result of chronic obstructive
pulmonary disease.
Means-Lerman "scratch" murmur: Increased
flow across the pulmonary valve in
Thyrotoxicosis may be associated with
ejection systolic murmur.The ejection systolic
murmur owing to hyperthyroidism may have
a scratchy quality (Means-Lerman scratch ),
and, frequently, the intensity of P2 is
increased because of mild to moderate
pulmonary hypertension.
Roger's Murmur:A loud pansystolic murmur
caused by interventricular septal defect of the
heart; maximal at the left sternal border.
Seagull murmur a raucous murmur with
musical qualities, such as that heard
occasionally in aortic insufficiency.A
"seagull’s cry murmur" is defined as a
murmur imitating the cooing sound of a
seagull. This type of murmur is typically
characterized by a musical timbre and a high
frequency, and may occur as a result of
various valve diseases. It is usually described
as a sign of tight calcific aortic stenosis,
when the murmur’s high frequency
components are transmitted to the lower left
sternal border and the cardiac apex during
most of systole (Gallavardin’s phenomenon).
In this condition, the typical harsh timbre of
the ejective murmur tends to assume a
musical high pitched quality, resembling that
of mitral regurgitation, which may be
reminiscent of the cry of a seagull. A
protodiastolic murmur with similar
characteristics, typically in decrescendo, may
occur in severe aortic valve regurgitation,
particularly when the regurgitant flow
presents high velocities. However, a seagull’s
cry murmur may also be the sign of mitral
regurgitation or prolapse. Similarly, the
musical and holosystolic sound reflects the
presence of high frequency components due
to high velocities of reflow.
Still's murmur An innocent musical murmur
resembling the noise produced by a twanging
string; almost exclusively in young children,
of uncertain origin and ultimately
disappearing.{There are five innocent
murmurs of infancy and childhood: (i)
pulmonary flow murmur, (ii) Still's murmur,
(iii) venous hum, (iv) carotid bruit, (v)
physiologic pulmonary branch stenosis
murmur of neonate}

Lines & Rings in Ophth
• Arlt’s Line = conjunctival scar in sulcus subtarsalis in Trachoma.
• Ehrlich-Turck Line = linear deposition of KPs in uveitis
• Ferry’s Line = corneal epithelial iron line at the edge of filtering blebs.
• Hudson-Stahil Line= Horizonatl corneal epithelial iron line at the inferior one third of cornea due to aging.
• Khodadoust Line = corneal graft endothelial rejection line composed of inflammatory cells.

• LASIK Iron Line: After LASIK for myopia, the central corneal curvature is flatter than before surgery. The tear film distribution is therefore altered, allowing some pooling centrally. This pooling can cause iron deposition in the central epithelium. A similar effect can be seen after steeping of the cornea from treatment of hyperopia. In the case of hyperopia, a pseudo-Fleischer’s ring iron deposition can be seen. These iron lines do not affect vision.
• Vogt’s striae occur centrally in a patient with keratoconus. By applying digital pressure on the eye while looking through the slit lamp, these striae in the deep cornea, mostly Descemet’s membrane, disappear, which is charac teristic of keratoconus.
• The Descemet’s breaks or Haab’s striae from birth trauma tend to be vertical, while the Descemet’s tears associated with congenital glaucoma tend to be horizontal or curvilinear.

• TED: Lid signs: These are: Retraction of the upper lids producing the characteristic staring and frightened appearance (Dalrymple’s sign); Lid lag (von Graefe’s sign) i.e., when globe is moved downward, the upper lid lags behind; Fullness of eyelids due to puffy oedematous swelling (Enroth’s sign); Difficulty in eversion of upper lid (Gifford’s sign); Infrequent blinking (Stellwag’s sign). Convergence weakness (Mobius’s sign)
• The Bruckner test is a way to estimate near-sightedness versus hyperopia.
Ratio in Ophth
• Kesten-Baum index refers to ratio of large blood vessels versus small blood vessels on the disc. Normal ratio is 4:16. This ratio is decreased in patients with optic atrophy.
• Cup-disc ratio. Normal cup disc ratio is 0.3. (i) Large cup may be physiological or glaucomatous. (ii) Cup becomes full in papilloedema and papillitis.
• Results of EOG are interpreted by finding out the Arden ratio as follows:
Arden ratio = (Maximum height of light peak/ Minimum height of dark trough) × 100 Normal curve values are 185 or above. Subnormal curve values are less than 150. Flat curve values are less than 125.
• Normal arterioles are bright red in colour and veins are purplish with a caliber ratio of 2: 3. Following abnormalities may be detected: Narrowing of arterioles is seen in hypertensive retinopathy, arteriosclerosis, and central retinal artery occlusion. Tortuosity of veins occurs in diabetes mellitus, central retinal vein occlusion and blood dyscrasias. Sheathing of vessels may be seen in periphlebitis retinae, and hypertensive retinopathy.
Operations in Ophth
• Fucala’s operation: Removal of clear crystalline lens for unilateral very high myopia
• McReynold’s operation: Transplantation of pterygium in the lower fornix, not performed now.
• Cicatricial entropion. 1. Resection of skin and muscle 2. Resection of skin, muscle and tarsus 3. Modified Burow’s operation 4. Jaesche-Arlt’s operation 5. Modified Ketssey’s operation
• Senile entropion. Commonly used surgical techniques are as follows: i. Modified Wheeler’s operation: ii. Bick’s procedure with Reeh’s modification: iii. Weiss operation. iv. Tucking of inferior lid retractors (Jones, Reeh and Wobig operation):
• Mechanical ectropion. It is corrected by treating the underlying cause. i. V-Y operation. ii. Z-plasty (Elschnig’s operation) iii. Excision of scar tissue and full thickness skin grafting.
• Congenital ptosis. It almost always needs surgical correction. In severe ptosis, surgery should be performed at the earliest to prevent stimulus deprivation amblyopia. However, in mild and moderate ptosis, surgery should be delayed until the age of 34 years, when accurate measurements are possible. Congenital ptosis can be treated by any of the following operations: 1. Fasanella-Servat operation. ( ans: Horner’s Syndrome) 2. Levator resection. (A)Conjunctival approach (Blaskowics’ operation): (B)Skin approach (Everbusch’s operation):
• The classical technique of lateral orbitotomy using S-shaped brow skin incision is called Kronlein’s operation, done for AXIAL PROPTOSIS.
• Seton operation: In this operation, a valvular synthetic tube is implanted which drains the aqueous humour from the anterior chamber into the subconjunctival space. It is performed for neovascular glaucoma and intractable cases of primary and other secondary glaucomas where medical treatment and conventional filtration surgery fail.
• TRIPPLE SNIP operation for Punctum block

Nerves and plexus

Arnold's nerve is the auricular branch (also known as the mastoid branch) of the vagus nerve.
Hering's nerve is the branch of glossopharyngeal nerve to the carotid sinus.
Nerve of Kuntz is a connection from the second intercostal nerve to the first thoracic ventral ramus.
The nerve of Henlé, a branch of the ulnar nerve in the forearm, is thought to deliver sympathetic innervation to the ulnar artery.
Arnold's nerve is also called Alderman's nerve.
Auerbach's plexus (or myenteric plexus) provides motor innervation to both layers of the tunica muscularis, having both parasympathetic and sympathetic input, whereas Meissner's plexus has only parasympathetic fibers and provides secretomotor innervation to the mucosa nearest the lumen of the gut.
The diagonal band of Broca is one of the forebrain nuclei that are derived from the ventral telencephalon during development. This structure forms the medial margin of the anterior perforated substance.
