JVD 2015 Flashcards
JVD 2015, Bilgic, Feline Oral Squamous Cell Carcinoma: Clinical Manifestations and Literature Review, which WAS not found to be a risk factor for developing SCC?
a) environmental tobacco smoke causes a 2 fold risk and tumors have higher p53 expression
b) flea collars 5.3x more likely to develop SCC
c) consumed canned food were 3.6x more likely to develop SCC
d) canned tuna 4.7x more likely
e) feline papillomavirus has been found to be a major cause of SCC
e) Human papillomavirus has been implicated in human head and neck SCC but this has not been readily found for cats with feline or human papillomavirus infection
JVD 2015, Bilgic, Feline Oral Squamous Cell Carcinoma: Clinical Manifestations and Literature Review, which of the following regarding treatment is in INCORRECT?
a) curative intent sx + RT may lead to best outcome
b) some promise in a combo therapy with started with induction of at least 2 weeks duration of weekly SQ bleomycin, oral piroxicam, and oral thalidomide then surgery or if no response, RT first then surgery–> ⅚ cats showed complete response with disappearance of all detectable tumor with 3 cats with lingual SCC alive at time of submission (the longest at 759 days!)
c) Chemotherapy alone has been shown to be effective for SCC
d) feline SCC have high numbers of COX2 enzyme expression so all SCC cats should receive an NSAID as part of their treatment
d) NSAIDs since inhibit COX that synthesis prostaglandins which may have antitumor effects however, most NSAIDs are COX2 inhibitors which only a small # of feline SCC express
JVD 2015, Bilgic, Feline Oral Squamous Cell Carcinoma: Clinical Manifestations and Literature Review, which is correct?
a) Oral tumors make up 10% of all feline tumors, and 90% of these are malignant, with SCC making up 60-70% of malignant oral tumors
b) Metastatic rate of 35.7% to mandibular lymph nodes, with low rate of pulmonary mets
c) Altered epidermal growth factor (EGFR) expression may play a role as a study found 9/13 samples (69%) had positive immunoreactivity for EGFR
d) FDG-PET appeared to provide better delineation of tumor margins than with CT alone
e) all of the above
e) all of the above
JVD 2015, Soukup, Classification and epidemiology of traumatic dentoalveolar injuries in dogs and cats: 959 injuries in 660 patient visits (2004-2012), which of the following was NOT considered a severe injury meaning it required timely intervention?
a) Lateral luxation
b) enamel-dentin-pulp fracture
c) intrusive luxation
d) avulsion
e) enamel infraction
e) enamel infraction
JVD 2015, Soukup, Classification and epidemiology of traumatic dentoalveolar injuries in dogs and cats: 959 injuries in 660 patient visits (2004-2012), what are the 14 TDI categories?
Concussion→ dx presence of blue, pink, or purple discolored tooth in absence of any other TDI
Extrusive luxation (SEVERE)
Intrusive luxation (SEVERE)
Subluxation→ dx slightly mobile tooth with no clinical or rad evidence of perio
Lateral luxation (SEVERE)
Avulsion (SEVERE)
Enamel infraction
Enamel fracture
Enamel-dentin (uncomplicated) fx
Crown root fx w/o pup involvement
Root fracture (SEVERE)
Enamel-dentin-pulp (complicated) fx (SEVERE)
Crown-root fx w/ pulp involvement (SEVERE)
Alveolar fracture
JVD 2015, Soukup, Classification and epidemiology of traumatic dentoalveolar injuries in dogs and cats: 959 injuries in 660 patient visits (2004-2012), what was the most common TDI?
1) enamel-dentin-pulp fx
2) root fracture
3) lateral luxation
4) enamel infraction
5) subluxation
enamel-dentin-pulp (complicated) fx 49.6%>concussion 14.4%.enamel-dentin (uncomplicated) fx 12.2%>crown root fx with pulp (complicated)10.8%>enamel fracture 4.1%>root fracture 3.5%>crown root fx w/o pulp (uncomplicated)1.9%>avulsion 1.6%>lateral luxation 0.8%>alveolar fx 0.3%>enamel infraction, extrusive luxation, and intrusive luxation 0.2%> subluxation 0.1%
JVD 2015, Soukup, Classification and epidemiology of traumatic dentoalveolar injuries in dogs and cats: 959 injuries in 660 patient visits (2004-2012), which of the following is correct?
1) There was no association b/w TDI and sex
2) There was a hyperbolic relationship with age meaning less common to have TDI < 3 years of age and > 10 years of age, with most common middle aged
3) Luxation injuries were found most commonly <3 years of age
4) Root fractures found almost exclusively in incisor teeth
5) all of the above
5) all of the above
JVD 2015, Soukup, Classification and epidemiology of traumatic dentoalveolar injuries in dogs and cats: 959 injuries in 660 patient visits (2004-2012), which is correct?
1) Majority of all injuries (70.7%) occurred in maxilla with most 58.7% affecting incisor/canine teeth
2) Most commonly injured teeth: canines 35.5% closely followed by premolars 33.6%>incisors 23.3%> molars 7.7%
3) Majority of TDI in “strategic” teeth ie caine and carnassial (ie 108/208,309/409) 60.9%, of the carnassials 92.2% were sustained by maxillary 4th premolar
4) Combining all fracture injuries, premolars (including 108/208) had highest frequency 39%>canine 33.3%>incisor 21%>molar 6.7%
Frequency of tooth fracture (not including alveolar fracture) 82.4%
5) Root fractures found almost exclusively in incisor teeth and more likely to occur in mandible vs maxilla
6) 66.8% of all TDI classified as severe
7) Concussive injuries 2nd most common injury at 14.4%
8) all of the above
8) all of the above
JVD 2015, Case report, Veterinary Dentistry at Work, Fecchio, Maxillary Calcifying Epithelial Odontogenic Tumor in a Siberian Tiger (Panthera tigris altaica), which is correct?
1) 1st report of a Calcifying epithelial odontogenic tumors (CEOT)in a tiger found distal to 104–> characterized by epithelial proliferation, mineralization of the epithelium and stroma, and deposition of amyloid or amyloid like material
2)has been proposed to change name to amyloid producing odontogenic tumor (APOT)
3) On histopath no evidence of neoplasia or odontogenic epithelium
4) Odontogenic epithelium is a tissue that contains cells that can form teeth. It’s made up of ameloblast-like cells and stellate reticulum cells, and is often surrounded by a cellular hyaline material; Odontogenic epithelium is also the origin of the epithelial lining of odontogenic cysts
5) all of the above
5) all of the above
