Some points in Angiofibroma:
-CT scan of the head with contrast enhancement is now the investigation of choice In angiofibroma.
-The most common presentation of angiofibroma is profuse, recurrent and spontaneous epistaxis.
-Most common origin of Angiofibroma is posterior part of nasal cavity close to the superior margin of sphenopalatine foramen.
-Antral sign or Holman-Miller is the anterior bowing of the posterior wall of maxillary sinus and is pathognomic of angiofibroma.
-Surgical excision is the treatment of choice.
-Recurrence of juvenile angiofibroma is not uncommon and has been reported in up to 35%.

In Nasopharyngeal Carcinoma:
-Commonest site of origin of NC in the nasopharynx is the fossa of Rosenmüller.
-Most common involved cranial nerve is VIth "Abducent" which is the first to be involved.
-Trotter’s triad:
1)Conductive deafness (eustachian tube blockage)
2)Ipsilateral temporoparietal neuralgia (involvement of CN V)
3)Ipsilateral palatal paralysis (CN X).
-The most common presentation in Ca Nx is Cervical lymphadenopathy (60–90%), then hearing loss and nasal obstruction.
-High-resolution, contrast-enhanced CT of neck and nasopharynx is the study of choice. "CECT"
-Radiotherapy is the treatment of choice for nasopharyngeal cancer.

In Lateral sinus thrombosis:
-Hectic Picket-fence type of fever with rigors.
-Crowe–Beck test:
Pressure on jugular vein of healthy side produces engorgement of retinal veins (seen by ophthalmoscopy) and supraorbital veins. Engorgement of veins subsides on release of pressure.

The characteristics of conductive hearing loss are:
1. Negative Rinne test, i.e. BC > AC.
2. Weber lateralized to poorer ear.
3. Normal absolute bone conduction.
4. Low frequencies affected more.
5. Audiometry shows bone conduction better than air conduction with air-bone gap. Greater the air-bone gap, more is the conductive loss.
6. Loss is not more than 60 dB.
7. Speech discrimination is good.

The characteristics of sensorineural hearing loss are:
1. A positive Rinne test, i.e. AC > BC.
2. Weber lateralized to better ear.
3. Bone conduction reduced on Schwabach and absolute bone conduction tests.
4. More often involving high frequencies.
5. No gap between air and bone conduction curve on audiometry.
6. Loss may exceed 60 dB.
7. Speech discrimination is poor.
8. There is difficulty in hearing in the presence of noise.

•Hennebert’s sign
A positive fistula sign in the absence of a fistula.This is due to fibrous adhesions between the stapes footplate and the membranous labyrinth.
•Tullio phenomenon in which loud sounds produce vertigo.

CHANCROID
Cause: H.ducreyi
Transmission: sexual
Primary lesion: Chancroid
Tender papule with erythematous halo that evolves to pustule, erosion, and ulcer. Ulcer is usually quite tender or painful .Its borders are sharp, undermined, and not indurated.With surrounding oedema. Base is friable with granulation tissue and covered with gray to yellow exudate.
Painful inguinal lymphadenitis (usually unilateral).
Dx: culture

Cause: Neisseria gonorrhoeae.
Transmission:Sexually,neonate during birth
Features: The most common presentation in males is a purulent creamy urethral discharge.
If not treated leads to "Disseminated gonococcal infection" which ccc by Hemorrhagic, painful pustules on erythematous bases on the palm and the finger of the other hand. These lesions occur at acral sites and are few in number.
DOC:
Ceftriaxone, 1 g IM or IV every 24 h.
