One of the only studies that are current with Cetacaine is the one that the FDA is conducting surrounding the issue of patients contracting methemoglobinemia from the use of Cetacaine. In these studies it was recorded that 319 cases were reported and out of the 319, 32 were considered life-threatening and 3 cases resulted in death. Economics
Cost effectivenss
Cetacaine has been used in the medical and dental field for a long time now. Its main competitors have been benzocaine and other benzocaine-based drugs. The use of Cetacaine has allowed for faster in and out times for patients, cheaper costs, easier use for the doctors or dentists needing to apply an anesthetic and better patient compliance (less anxiety).Cetacaine compared to some of the leading competitors is considered by most a cheaper option. For the spray option the bottle containing 56g can dispense 100 doses and only cost the dentist $0.79 per dose. The liquid Cetacaine that comes in the 30 g bottle can dose 73 full mouths at a cost of about $0.75 per dose. Manufacturer
The company the makes Cetacaine is called Cetylite Industries, Inc. This company is based out of Pennsauken, NJ and has a total of 75 employees. Cetylite brings in total revenue of around $7,500,000 with their main product being the topical anesthetics, and infection prevention products. == References ==
This can be due to genetic errors such as the deletion or mutation of a segment of chromosome 15, uniparental disomy, or translocation. While Angelman syndrome can be caused by a single mutation in the UBE3A gene, the most common genetic defect leading to Angelman syndrome is a 5- to 7-Mb (megabase) maternal deletion in chromosomal region 15q11.2-q13.Specifically, the paternal copy of UBE3A is known to be imprinted within the hippocampus, cortex, thalamus, olfactory bulb, and cerebellum. Therefore, in these areas of the brain, a functioning maternal copy of UBE3A is essential for proper development.Region 15q11-13 is implicated in both Angelman syndrome and Prader–Willi syndrome (PWS). While AS results from mutation, loss or abnormal imprinting involving the UBE3A gene within this region on the maternal chromosome, loss of a different cluster of genes within the same region on the paternal chromosome causes PWS.The methylation test that is performed for Angelman syndrome looks for methylation on the genes neighbor SNRPN, which is silenced by methylation on the maternal copy of the gene. Neurophysiology
The electroencephalogram (EEG) in AS is usually abnormal, more so than clinically expected. This EEG facilitates the differential diagnosis of AS, but is not pathognomonic. Three distinct interictal patterns are seen in these patients. The most common pattern is a very large amplitude 2–3 Hz rhythm most prominent in prefrontal leads. Next most common is a symmetrical 4–6 Hz high voltage rhythm. The third pattern, 3–6 Hz activity punctuated by spikes and sharp waves in occipital leads, is associated with eye closure.
