Retrospective Review of Oral Probiotic Therapy.

Purpose: There have been many in vitro studies reporting on the efficacy of probiotic bacteria in inhibiting pathogens, and there have been published studies reporting on the inhibitor effects of probiotic bacteria on the salivary levels of bacterial pathogens. However, there have not been but a few studies on the clinical benefits of oral probiotic therapy. Study design: Dental records of 60 patients that were enrolled in an Institutional Review Board approved study were reviewed as to current caries activity status with measurement of the Decayed Missing Filled Teeth index and by Caries Management By Risk Assessment (CAMBRA) determination. The current oral health status was compared to the prior-to-study enrollment status and then analyzed in respect to published national norms. The data (without any identifiers) had a statistical analysis by a blinded biostatistician. The data was subjected to statistical analysis (Statsgraphic) before and after the probiotic therapy. Results: Of the 53 subjects available for follow up, only 4 had remained caries active with a grand total of 27 carious lesions being detected and subsequently restored in this group. Of the original total of 60 patients with 292 initial carious lesions, after probiotic therapy and dental restoration, 78 total restorations were placed in the subject group over the following three years. Approximately half of these restorations were required in teeth that had initially presented with smaller lesions and had been placed in a "watch" category. Two of the patients that developed further carious lesions had been randomly assigned to the probiotic PerioBalance, while the other two caries active patients were assigned EvoraKids probiotic. Of the original group of caries active patients, 24 did not present with any further carious involvement. Another 25 could be categorized as caries static, as the restorations required were substantially less than before probiotic therapy had been begun. The F-ratio, which in this case equals 51.3313, is a ratio of the between-group estimate to the within-group estimate. Since the P-value of the F-test is less than 0.05, there is a statistically significant difference between the means of the 4 variables at the 95.0% confidence level. Conclusion: The tested probiotic supplements had a statistically significant effect on the caries experience of the enrolled subjects.

Clinical Features and Computed Tomography Findings Are Utilized to Characterize Retrobulbar Disease in Dogs.

The objective of this study is to describe the clinical features and computed tomography (CT) findings of dogs with retrobulbar disease. There are two facets to this study: a retrospective case series in which findings of dogs with primary vs. secondary retrobulbar disease are described, and a retrospective cross-sectional study in which computed tomography findings of dogs with retrobulbar neoplasia vs. infection/inflammation are described and compared. The medical records of 66 client-owned dogs diagnosed with retrobulbar disease between 2006 and 2016 were reviewed. Clinical information including signalment, the specialty service to which the dog was presented, clinical signs, physical examination findings, diagnostic results, treatment, and outcome were documented. Diagnostic imaging and histopathology were reviewed. Forty-one dogs (62.1%) were diagnosed with primary disease of the retrobulbar space; 25 dogs (37.9%) were considered to have secondary retrobulbar disease. Of the 41 dogs with primary retrobulbar disease, 19 were diagnosed with neoplasia, 19 with infectious/inflammatory disease, and 3 suffered traumatic insult to the retrobulbar space. Of the 25 dogs with secondary retrobulbar disease, 21 were diagnosed with neoplasia, 3 with infectious/inflammatory disease, and 1 with a cyst. Dogs had a combination of ocular, oral, and/or nasal clinical signs. CT findings of orbital osteolysis, orbital periosteal reaction, and presence of a retrobulbar mass were significantly associated with neoplasia, while zygomatic salivary gland enlargement, retrobulbar mass effect, and mandibular lymphadenopathy were more often associated with infectious/inflammatory disease. CT findings overlap among different retrobulbar diseases, but new bone formation and lysis are more often associated with neoplasia. Disease originating from the retrobulbar space was equally likely to be infectious/inflammatory (n = 19) or neoplastic (n = 19), based on definitive diagnostic results of dogs with primary retrobulbar disease. Due to the clinical ramifications of these disorders, the diagnosis and treatment of these cases should be managed with a multi-specialty approach.
