Sensory Reflexes

This lesson covers the examination of the Sensory reflexes of the upper extremities. You can check the deep tendon reflexes using impulses from a reflex hammer to stretch the muscle and tendon. The limbs should be in a relaxed and symmetric position, since these factors can influence reflex amplitude. As in muscle strength testing, it is important to compare each reflex immediately with its contralateral counterpart so that any asymmetries can be detected.



USMLE: Rinne's Test

Rinne's test consists of comparing bone conduction (placing the tuning fork on the mastoid process) versus air conduction (placing the tuning fork in front of the pinna). Normally, air conduction is greater than bone conduction. For neurosensory hearing loss, air conduction is still greater than bone conduction but for conduction hearing loss bone conduction will be greater than air conduction.

USMLE: Oropharynx Exam

This session focuses on examination of the oropharynx and the procedure to check if any types of diseases or abnormalities can be found.

Tips: Ask the patient to open widely, relax and slowly breathe in and out saying “Ahhh”. This relaxes the tongue allowing a view of the oropharynx. It may be necessary to press down on the back of the tongue to get a full view of the oropharynx. Simply depressing the tongue with a tongue blade and having the patient say “ah,” often gives only a superficial view of the oropharynx and many early cancers may go unnoticed. The palatine tonsils can be seen on both sides behind the retromolar trigone. Examine the anterior and posterior tonsillar pillars and tonsillar fossa for any exophytic mass, asymmetry, ulceration, or redness.



Early Childhood Healthcare

Parents always want the best healthcare for their children. The American Academy of Pediatrics is recommending parents to give their children vaccinations that would immunize them from potentially life-threatening diseases. This is a big year for immunizations that includes 4 different vaccines that parents should be aware. They include an oral Rotavirus vaccine for all infants, Varicella or Chicken Pox vaccine, Flu vaccine, and HPV vaccine for girls to prevent cervical cancer.
