Expansion of osteopathic medicine practitioner education on substance use disorders.

CONTEXT: Medical school graduates are generally not well prepared to treat patients with substance use disorders (SUDs), even though opioid overdose deaths in the United States have increased in recent years. When it comes to training in SUDs, osteopathic medicine lags far behind allopathic medicine. It was only in 2019 that the American Osteopathic Association approved Board Certification in Addiction Medicine to help combat the opioid epidemic. Few articles have been published in the literature pertaining to substance use education for osteopathic students and trainees. OBJECTIVES: The goal of this study was to expand the education of osteopathic medical students and primary care residents in SUDs and measure the effect that education had on the attitudes and knowledge of student and residents about SUDs. METHODS: This study collected anonymous data in the form of a voluntary online survey from third- and fourth-year students at an osteopathic medical school and family medicine residents. The survey was completed by 115 students and 29 family medicine residents. Participants completed a pretest survey and then participated in the Physician Undergraduate and Resident Substance Use Education (PURSUE) curriculum developed by the researchers. This consisted of three online modules covering Screening, Brief Intervention, and Referral to Treatment (SBIRT), substance use assessments, and treatment of SUDs. Upon conclusion of the training modules, medical student participants then completed a posttest survey to assess for any changes in knowledge and attitude. Participants also answered questions related to clinical case scenarios involving patients at varying risk levels who were assessed utilizing SBIRT. RESULTS: Students and residents who participated in the training demonstrated an increase in their average scores between the pretest and posttest, indicating effectiveness in learning from the modules. The overall increase in average scores on the pretest and posttest was 6.5 %, which was determined to be statistically significant (p<0.01). Interestingly, participants who reported growing up in underprivileged circumstances performed worse than those participants who reported not growing up in underprivileged circumstances. CONCLUSIONS: The results of our project support the need and benefit of incorporating educational modules on this topic area within medical school curriculums and residency training. Expanding the number of healthcare workers proficient in providing this type of care in these types of settings will improve the quality of and access to medical care in some of our highest-need populations.

Theophylline increases saliva sonic hedgehog and improves taste dysfunction.

OBJECTIVE: To determine changes in saliva sonic hedgehog (Shh) and in taste dysfunction before and after oral theophylline treatment. DESIGN: Shh was measured in parotid saliva of both normal subjects and patients with taste dysfunction of multiple etiologies by use of a sensitive spectrophotometric ELISA assay. Taste dysfunction was defined clinically by both subjective inhibition of taste function (including acuity loss) and impaired gustometry. RESULTS: Theophylline treatment increased patient saliva Shh and improved taste dysfunction both subjectively and by gustometry. CONCLUSIONS: By use of these systematic clinical measurements theophylline can be demonstrated to increase saliva Shh and improve taste dysfunction. These results are consistent with saliva Shh acting as a taste bud growth factor which stimulates stem cells of taste buds to initiate development and perpetuation of taste bud receptors. Measurements of saliva Shh provide an important marker for the presence of taste dysfunction and in the improvement by theophylline treatment.

Sonic hedgehog is present in parotid saliva and is decreased in patients with taste dysfunction.

PURPOSE: To demonstrate that sonic hedgehog (Shh) is present in human parotid saliva and is decreased in human taste dysfunction. METHODS: Shh was measured in parotid saliva of 27 normal subjects and 81 patients with taste dysfunction of multiple etiologies using a sensitive spectrophotometric ELISA assay. Taste dysfunction was defined clinically both by subjective decreases of taste acuity and flavor perception and by impaired gustometry. RESULTS: Shh was found in parotid saliva of both normal subjects and patients with taste dysfunction. Levels were significantly lower in patients than in normal subjects. Both subjective loss of taste acuity and flavor perception and impaired gustometry was measured in untreated patients. CONCLUSIONS: This is the first demonstration of Shh in human saliva. As Shh has been related to taste bud growth and development, its presence in saliva is consistent with its role as a cell signaling moiety involved with stimulation of taste bud stem cells to generate taste receptors. Decreased saliva Shh secretion can be considered a marker of taste dysfunction in patients with multiple pathologies for their dysfunction.

Improved smell function with increased nasal mucus sonic hedgehog in hyposmic patients after treatment with oral theophylline.

PURPOSE: We previously demonstrated the presence of sonic hedgehog (Shh) in nasal mucus in normal subjects and in patients with smell loss (hyposmia). Nasal mucus Shh levels were found significantly diminished in untreated hyposmic patients of multiple etiologies. Since treatment with oral theophylline has been previously associated with improvement in smell function we wished to study if such treatment increased nasal mucus Shh as well as improved smell function in patients with hyposmia. METHODS: Forty-four patients with hyposmia of several etiologies were evaluated for changes in hyposmia by subjective measurements of smell, taste and flavor perception and by olfactometry. Measurements of nasal mucus Shh were made in relationship to each set of sensory measurements. Patients were treated with oral theophylline at doses of 200-800mg for periods of 2-10months with sensory function, nasal mucus Shh and serum theophylline levels evaluated at these time intervals. Nasal mucus Shh measurements were made with a sensitive spectrophotometric ELISA assay and theophylline with a fluorometric assay. RESULTS: There was consistent, significant improvement in subjective responses in smell, taste and flavor perception and in olfactometry associated with increased nasal mucus Shh and serum theophylline after theophylline treatment. CONCLUSIONS: Improvement in smell function and in nasal mucus Shh was positively correlated in a dose-response relationship after treatment with oral theophylline. Results are consistent with a successful role for theophylline in improvement of smell function in hyposmic patients of multiple etiologies associated with increased nasal mucus Shh which can act as a biochemical marker for smell function.
