Syphilis is a sexually transmitted infection (STI) caused by bacteria. Syphilis is spread through direct contact with the sores of an infected person. This usually happens through sexual activity, especially unprotected sex. It can also spread through sharing needles or contact with the blood of an infected person. If you are pregnant, you can give syphilis to your baby.
Simultaneous red reflex test [edit]. The simultaneous red reflex test is used to view both reflexes at the same time. This can help determine if the patient has normal ocular alignment. In order to perform this test the patient and physician are normally approximately 2 to 3 feet away from each other.imultaneous red reflex test [edit].

From a clinical perspective, reflexes are extremely important. The stretch reflex is most important and is tested routinely. The flexion reflex is seldom tested, except in unconscious patients.Pain pathways usually are checked by testing for conscious sensibility to pin prick (see Chapter 5). Passive limb movement causes a stretch reflex in the muscles being stretched and their reflex contraction resists further movement of the limb. 2  The resistance is velocity sensitive, being greater the faster the limb is moved. 3  Clasp knife reflex.
