Mixed salivary pools of normal subjects and patients with galvanism, yeast-induced stomatitis, and diabetes mellitus were examined. The examinations have revealed elevated alpha-amylase levels in the patients with galvanism and still higher levels of this enzyme in yeast-induced stomatitis and diabetes mellitus. These diseases are also associated with a rise of lactoferrin content and with appearance of fibrinogen degradation products.

Ten yearling white-tailed deer (Odocoileus virginianus) were inoculated with bluetongue virus serotype 17. Two yearling white-tailed deer were inoculated with sonicated heparinized noninfected blood and served as controls. Clinical signs of bluetongue virus infection included increased rectal temperature, erythema, facial edema, coronitis, and stomatitis. By postinoculation day (PID) 8, excessive bleeding and hematoma formation at venipuncture sites, dehydration, and diarrhea developed. At necropsy, the most consistent findings were oral lesions and widespread hemorrhage, which ranged from petechia to massive hematoma formation. Bluetongue virus caused progressive prolongation of activated partial thromboplastin time and prothrombin time, and progressive reduction of Factors VIII and XII plasma activities beginning on PID 6. A progressive decrease in platelet numbers also developed on PID 6. Changes in platelet size were not detected. Mean thrombin time was shortened, but prolongation developed in 1 deer. Mean fibrinogen concentration and Factor V plasma activity initially increased and then decreased, but remained above preinoculation values. Factor V activity was low in a few deer. Results of screening tests for inhibitors of the intrinsic coagulation system were positive in 2 deer. High concentrations of fibrin(ogen) degradation products were first detected between PID 3 and 6. Hematologic changes included leukopenia, lymphopenia, neutrophilia, and low total plasma protein concentration. Differences in PCV, hemoglobin concentration, or RBC counts were not detected between infected and control deer. Serum total bilirubin concentration increased by PID 6, primarily because of increased unconjugated bilirubin concentration. Mild to severe increases in serum aspartate transaminase activity were accompanied by more marked increases in creatine kinase activity. Indirect Coombs test results were negative in all deer.(ABSTRACT TRUNCATED AT 250 WORDS)

During 1992, a widespread outbreak of Equine viral arteritis (EVA) occurred at a riding establishment near Barcelona, Spain. A total of 31 out of 186 horses on the premises displayed clinical signs, most frequently, fever, depression, mild ventral and limb oedema and a vesicular-erosive stomatitis, with hypersalivation, petechiations and small ulcerations. Affected horses developed illness of varying severity with only a few exhibiting a severe form of the disease and no mortality was recorded. Haematological and blood biochemical examination the most severely affected horses revealed a thrombocytopenia, slight leucocytosis with neutrophilia, lymphopenia and eosinopenia, an increase in plasma fibrinogen and a small rise in serum proteins and indirect bilirubin values. Diagnosis was confirmed by demonstration of seroconversion to equine arteritis virus in acute and convalescent phase sera. Attempted isolation of the virus from citrated blood samples proved unsuccessful.

Fibrinogen solutions were irradiated with UVC (254 nm) to inactivate contaminating viruses. In order to protect fibrinogen during UVC irradiation, 0.5 mM rutin was added prior to UVC exposure and subsequently removed during processing. Viral kill by 0.1 J/cm2 UVC resulted in the following inactivation values (log 10): non-lipid-enveloped viruses: Parvo > or = 5.5; encephalomyocarditis virus > or = 6.5; hepatitis A virus > or = 6.5: lipid-enveloped viruses: human immunodeficiency virus > or = 5.7; vesicular stomatitis virus > or = 5.7. Fibrinogen irradiated with 0.5 mM rutin did not significantly differ from unirradiated material in terms of clot time and breaking strength. In the absence of rutin, UVC irradiation of fibrinogen at similar fluence led to loss of solubility, increased clot time and the cleavage of fibrino-peptides that reacted with dinitrophenyl hydrazine as a test for ketonic carbonyl groups. High-performance liquid chromatography and mass spectrometry data showed that rutin exposed to UVC formed numerous breakdown, oxidation and combinational products. Experiments with 3H-rutin showed that after UVC irradiation, subsequent processing by a C18 resin and alcohol precipitation removed > 99% rutin, representing < 10 ppm rutin in the final fibrinogen preparations. Residual 3H-rutin was not covalently bonded to the fibrinogen. Immunochemical studies with rabbit antisera to UVC irradiated (with rutin) fibrinogen showed the absence of neoimmungens. By all measures, rutin prevents fibrinogen degradation during virucidal UVC irradiation.

Tumor-selective oncolytic vesicular stomatitis viruses (VSVs) are being evaluated in clinical trials. Here, we report that the MPC-11 murine plasmacytoma model is so extraordinarily susceptible to oncolytic VSVs that a low dose of virus leads to extensive intratumoral viral replication, sustained viremia, intravascular coagulation, and a rapidly fatal tumor lysis syndrome (TLS). Rapid softening, shrinkage and hemorrhagic necrosis of flank tumors was noted within 1-2 days after virus administration, leading to hyperkalemia, hyperphosphatemia, hypocalcemia, hyperuricemia, increase in plasma cell free DNA, lymphopenia, consumptive coagulopathy, increase in fibrinogen degradation products, decreased liver function tests, dehydration, weight loss, and euthanasia or death after 5-8 days. Secondary viremia was observed but viral replication in normal host tissues was not detected. Toxicity could be mitigated by using VSVs with slowed replication kinetics, and was less marked in animals with smaller flank tumors. The MPC-11 tumor represents an interesting model to further study the complex interplay of robust intratumoral viral replication, tumor lysis, and associated toxicities in cases where tumors are highly responsive to oncolytic virotherapy.

Chronic ulcerative stomatitis (CUS) is a poorly understood disease with clinical and histologic overlap with lichen planus (LP). Unlike classic LP, direct immunofluorescence (DIF) studies in cases of CUS exhibit a granular pattern of IgG in nuclei of basal and parabasal cells. This study assesses the demographic, clinical, histologic, and DIF features of CUS. It is important to differentiate CUS from LP and other vesiculobullous diseases (VBD) because lesions of CUS are resistant to steroid therapy, which is typically used to control LP and VBD. A literature review and IRB-approved retrospective search of CUS was performed within the archives of the University of Florida (UF) Oral Pathology Biopsy Service from 2007 to 2017. Fifty-two cases were identified from the literature and seventeen new cases were identified in our series. All UF patients were female and the median age was 64-years. The majority of patients were Caucasian and the most common location was buccal mucosa. Frequent clinical presentations were pain, erythema, leukoplakia, and ulcerations. Histologic features included epithelial separation, atrophic epithelium, and a chronic inflammatory infiltrate. All cases were confirmed with DIF testing that showed a speckled pattern of IgG staining in basal and parabasal cell nuclei. Fibrinogen was present in eleven cases and two cases were positive for C3. The results of our series are in accordance with the literature. Since CUS has overlapping features with LP and VBD, clinicians and pathologists should consider this entity and confirm diagnosis with DIF testing when recalcitrant oral ulcerative diseases are encountered.
