Bisphosphonate therapy in chronic diffuse sclerosing osteomyelitis/tendoperiostitis of the mandible: Retrospective case series

This study aims to evaluate short-term and long-term results of bisphosphonate therapy in patients with diffuse sclerosing osteomyelitis/tendoperiostitis (DSO/TP) of the mandible.Eighteen patients (12 female, 6 male) aged 34.8 ± 22.2 years with DSO/TP of the mandible that were treated with bisphosphonates were included. In 16 patients, the bisphosphonate treatment led to remission with decrease of symptoms (pain, swelling of the cheek, trismus, tenderness of masticatory muscles) with a follow-up period of 4.5 (0.8–11.9) years between start of bisphosphonate treatment and latest follow-up consult. Of these, three patients were still in need of regular bisphosphonate therapy. Two patients were lost to follow-up.Bisphosphonate therapy is a treatment option for DSO/TP of the mandible that is associated with a high chance of remission of symptoms. Within the limitations of the study it seems that this treatment might be an effective second step in DSO/TP refractory to conservative treatment.

The reliability in determining the deep fascia displacement of the upper trapezius during cervical movement: A pilot study

BackgroundRestricted shoulder fascia displacement may be an etiological factor for myofascial pain syndrome. A diagnostic ultrasound video can follow deep fascia displacement during active cervical movements. Trackers can be applied to videos to convert deep fascia displacement into data points. This study reports on assessors' reliability in evaluating direction and quantifying upper trapezius' deep fascia displacement during active cervical movements.MethodsPT-Sonographer 1 recorded deep fascia displacement of upper trapezius for three sets using HS1 Konica Minolta diagnostic ultrasound. The recording sequence used was cervical flexion, extension, right lateral flexion, left lateral flexion, right rotation, and left rotation. The three assessors used the tracker to determine direction of deep fascia displacement. PT-Sonographer 1 used the tracker three times in quantifying deep fascia displacement. Intraclass correlation coefficient and Kappa determined the assessors' intra-tester and inter-tester reliability.ResultsTen participants were included in the study with a mean±(SD) age of 37±(6). All the assessors had acceptable intra-tester reliability in determining deep fascia displacement on tracker (ICC≥0.40). All assessors had clinically unacceptable inter-tester reliability in determining deep fascia displacement when tracking right rotation (ICC < 0.40). PT-Sonographer 1 had clinically unacceptable intra-tester reliability in determining deep fascia displacement when tracking left rotation (ICC<0.40).ConclusionWe report clinically acceptable assessors' reliability in determining direction and total deep fascia displacement when tracking diagnostic ultrasound videos of cervical flexion, extension, and lateral flexion. Checking for reliable deep fascia displacements may distinguish MPS from non-MPS individuals increasing the utility of diagnostic ultrasound machine and tracker in clinical practice.     

Immediate effects of rhythmic joint mobilization of the temporomandibular joint on pain,mouth opening and electromyographic activity in patients with temporomandibular disorders

BackgroundRhythmic joint mobilizations (RJM) of the temporomandibular joint (TMJ) are employed to relieve pain and improve function in patients with temporomandibular disorders (TMD). However, the evidence on the immediate effects of RJM in patients with TMD is scarce. The aim of this study was to assess the immediate clinical and functional effects of RJM in patients with TMD.Materials and methodsThis was a one-group quasi-experimental before and after study. Thirty-eight patients with TMD were assessed by means of pain intensity (visual analogue score, VAS), pressure pain threshold (PPT, measured through pressure algometry on the masseter and temporal muscles), mouth opening (MO, measured with a ruler), and surface electromyographic activity of the masseter and temporal muscles (asymmetry index, AI). Measurements were performed before and after a single, 1-min session of RJM of each TMJ. All statistical analyses were performed using the SPSS version 20.0 statistical package.ResultsA statistical significant difference was found in pain intensity, PPT and MO after the intervention (p < 0.05). No difference was found in the AI. A large effect size was observed for pain intensity, PPT of the left and right masseter muscles and MO (d = 0.85–1.13), whereas for the left and right temporal muscles the effect size was moderate (d = 0.62) and small, respectively (d = 0.49).ConclusionIn this sample of patients with TMD, a single session of RJM of the TMJ seemed to be effective in reducing pain intensity, increasing PPT and improving MO immediately after the intervention, without differences in the AI.     

Diagnosis of intrahepatic cholangiocarcinoma by Raman spectroscopy provides high efficiency: A protocol for systematic review and meta-analysis

Background:We aim to evaluate the efficiency of Raman spectroscopy (RS) in diagnosing suspected patients with intrahepatic cholangiocarcinoma (ICC), manifested by diagnostic sensitivity, specificity, and accuracy.Methods:We will research widely the articles concerning the use of RS in ICC through authenticated database including PubMed/Medline, EMBASE, Web of Science, Ovid, Web of Knowledge, Cochrane Library, and CNKI between January 2012 and November 2020, retrieving at least 1500 spectra with strict criteria. This study will be carried out in accordance to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We are going to summarize the test performance using random effects models.Results:Based on the pooled sensitivity, specificity, and diagnostic accuracy, we intend to provide the relative diagnostic efficiency in ICC through RS.Conclusion:Through this systematic review and meta-analysis, we intend to provide the pooled sensitivity, specificity and diagnostic accuracy of RS in the diagnosis of suspected ICC. Other parameters like positive likelihood ratios (LR), negative LR, diagnostic odds ratio (DOR), and area under curve (AUC) of the summary receiver operating characteristics (SROC) curve will also be calculated and related figures will be drawn to help illustrate the efficacy of RS in the diagnosis of ICC.
