SUNCT syndrome

SUNCT is an acronym for Short-lasting, Unilateral Neuralgiform Pain with Conjunctival injection and Tearing .

The pain typically occurs as repetitive paroxysms of unilateral moderate to severe pain in the ocular and periocular area lasting 1-2 minutes in duration.

Pain can spread to the upper jaw, the roof of the mouth or the front of the temporal areas of the head.

Interestingly, the pain strikes only during the daytime and is described as steady and nonthrobbing.

The pain is associated with ipsilateral conjunctival injection, nasal congestion, rhinorrhea, forehead sweating and lacrimation.

The conjunctival injection and lacrimation can have a volatile characteristic during severe attacks, coming on suddenly and severely.

This syndrome almost always strikes men of middle to old age

TREATMENT

Although indomethacin and carbamazepine have been used much, there is no evidence that either help. Corticosteroids may be beneficial, but are untested. There has been no clearly effective therapy, and successful treatment has been anecdotal.

Anaphylaxis updates part 2- Empty Ventricle Syndrome

Patients with anaphylaxis should not suddenly sit, stand, or be placed in the upright position. Instead, they should be placed on the back with their lower extremities elevated or, if they are experiencing respiratory distress or vomiting, they should be placed in a position of comfort with their lower extremities elevated. This accomplishes 2 therapeutic goals: 1) preservation of fluid in the circulation (the central vascular compartment), an important step in managing distributive shock; and 2) prevention of the empty vena cava/empty ventricle syndrome, which can occur within seconds when patients with anaphylaxis suddenly assume or are placed in an upright position. Patients with this syndrome are at high risk for sudden death. They are unlikely to respond to epinephrine regardless of route of administration, because it does not reach the heart and therefore cannot be circulated throughout the body

Steroids In Perioperative period...The Multi-purpose Drugs

1-Steroids are not Bronchodilator ,but have well established usefulness in hyper-reactive airway. They are also said to have a permissive role for bronchodilator medication. They can be administered orally, parenterally or in aerosol form 2- Steroids have been commonly used in chemotherapy for prevention of nausea along with other anti-emetic agents . Dexamethasone was found to be highly effective when given immediately before induction rather than at the end of anesthesia . 3- Steroids do exert analgesic effects. Various routes of administration of steroids include parentral, local infiltration at operated site , as an adjuvant in nerve blocks and central-neuraxial blockade. 4 - Steroids cannot be the mainstay of therapy in anaphylaxis because of the delayed onset of action, so they are used as adjunct after initial treatment with epinephrine. 5- Steroids (Dexamethsone) are of value in reduction or prevention of cerebral edema associated with parasitic infections and neopla...
