Photodynamic therapy in oral potentially malignant disorders—Critical literature review of existing protocols

IntroductionOral cancer is a serious public health issue. Apart from its high rate of prevalence, incidence and mortality, it can often result in more complex and expensive treatment when diagnosed late. Potentially malignant disorders (PMDs) can precede oral cancer, and are usually treated by surgical excision. However, in many cases patients are elderly and multiple interventions may be required. Photodynamic therapy (PDT) is a simple alternative, which has been successfully used in the treatment of oral PMDs.ObjectiveDue to the lack of standardization regarding photosensitizers (PTSs), types of irradiation, and methods of application, the objective of this study was to analyze existing PDT protocols in an attempt to identify the one that demonstrates greater efficiency, reliability and feasibility in the treatment of oral PMDs for both researchers and clinicians.MethodsOriginal clinical studies published only in English between 1993 and 2016 were searched in Pubmed/Medline database using the following keywords: photodynamic therapy; oral potentially malignant disorder; oral premalignant lesions. Review articles; experimental studies; case-reports; commentaries; and letters to the Editor were excluded from the selection.Results and conclusionBased on the 16 studies selected, the topical 5-ALA-20% PTS, associated to a LED light applied for 15 min with a 7-day interval between sessions emerged as the most frequently used PDT protocol, with satisfactory results. Due to its low rate of side effects, this PDT protocol presents good potential for the treatment of oral PMDs. Further clinical studies are required to ascertain its long-term validity in preventing oral cancer.     

New oral cut-off time limits in NSW

Standard collection procedure for the investigation of allegations of penile - oral assault has traditionally been the oral swab. Review of both the literature and NSW forensic laboratory results from oral swabbing has highlighted the sub-optimal nature of this method for the recovery of both sperm and offender DNA.554 oral swabs, collected in NSW from 2010 to 2015, were analysed. Sperm detection occurred in only 4.2%. In the same period there was analysis of 104 oral rinses (of which 16.4% were positive for sperm) and 71 peri-oral samples (of which 18.3% were positive for sperm).As a result, a decision was made to revise forensic collection guidelines for sample collection in cases of penile - oral assault. Oral swabbing is no longer recommended. Current NSW forensic collection guidelines recommend the collection of both an oral rinse and a peri-oral (lip) swab. Samples are to be taken in the first 12 h after a penile - oral assault in all cases where there is a suspicion of oral assault. Oral collections may be extended to 24 h post penile - oral assault in those cases where there is either a clear recollection of ejaculation into the mouth (or ejaculation elsewhere prior to penile penetration of the mouth) or in those cases where a complainant is clear that there had been penile penetration of the mouth but is unable to recall whether or not ejaculation has taken place.     

Mock radiology oral examination

RATIONALE AND OBJECTIVE: To organize and implement a mock oral examination for radiology residents in an attempt to prepare them for the American Board of Radiology Oral Examination. MATERIALS AND METHODS: A mock oral examination was administered to junior and senior radiology residents by radiology faculty. All participants completed postexamination surveys. RESULTS: The mock oral examination process not only provided practice for preboard residents, but also determined areas of deficiency in their fund of knowledge and presenting skills. Additionally, it provided faculty members with areas of curricular weakness. CONCLUSION: Administration of a mock oral examination reaps multiple benefits, which far exceed the task of its implementation.     

CT of the oral vestibule with distended cheeks

Purpose: To evaluate patient compliance in CT examination of the oral vestibule with distended, blown-up cheeks and to determine how often such images provided additional information when disease processes in this area were suspected.Material and Methods: Fifty-four patients were examined with CT of the oral vestibule with distended cheeks and 16 of them had diseases where oral vestibule affection was considered possible.Results: Fifty-three of 54 patients were able to perform cheek distension. Of 16 patients with possible disease involvement of the oral vestibule, additional information was thus obtained in 11 patients.Conclusion: When lesions involving the oral vestibule or adjacent regions are suspected, CT examination with distended cheeks is recommended as a routine procedure.
