Physical therapy in addition to occlusal splint in myogenic temporomandibular disorders: A randomised controlled trial.

BACKGROUND: Myogenic temporomandibular disorders (M-TMD) commonly involve occlusal splint (OS) therapy and musculoskeletal physiotherapy (MPT). OBJECTIVES: To compare the effects of combining OS with MPT and education (EG) against OS and education (CG), in chronic M-TMD patients. METHODS: In this double-blind randomised controlled trial, 62 participants were assigned to either EG or CG. The primary outcomes, pain levels at rest (VAS rest), maximum oral opening (VAS open) and during chewing (VAS chew), were measured by Visual Analogue Scale (VAS) in cm. The secondary outcome was the range of motion (ROM) for maximum oral opening. Both interventions lasted 3 months, with outcomes assessed at baseline (T0), post-treatment (T1) and 3 months post-treatment (T2). RESULTS: Intention-to-treat analysis revealed significant improvements favouring EG (VAS rest = -1.50 cm [CI95%: -2.67, -0.32], p = .04; VAS open = -2.00 cm [CI95%: -3.23, -0.75], p < .01; VAS chew = -1.71 cm [CI95%: -2.90, -0.52], p = .01; ROM = 4.61 [CI95%: 0.93, 8.30], p = .04). Additionally, VAS measures were influenced by follow-up times (VAS rest = -0.73 cm [CI95%: -1.30, -0.17], p = 0.03; VAS open = -0.97 cm [CI95%: -1.57, -0.37], p < .01; VAS chew = -1.15 cm [CI95%: -1.73, -0.58], p < .01). At T1, EG demonstrated higher number of responders compared to CG for VAS open (χ2(1) = 4.39, p = .04) and VAS chew (χ2(1) = 11.58, p < .01). CONCLUSION: Adding MPT to education and OS yields better outcomes in terms of pain reduction and ROM improvement, in chronic M-TMD. TRIAL REGISTRATION NUMBER: NCT03726060.

The accuracy of pain drawing in identifying psychological distress in low back pain-systematic review and meta-analysis of diagnostic studies.

The aim of this systematic review and meta-analysis was to estimate the accuracy of qualitative pain drawings (PDs) in identifying psychological distress in subacute and chronic low back pain (LBP) patients. [Subjects and Methods] Data were obtained from searches of PubMed, EBSCO, Scopus, PsycINFO and ISI Web of Science from their inception to July 2014. Quality assessments of bias and applicability were conducted using the Quality of Diagnostic Accuracy Studies-2 (QUADAS-2). [Results] The summary estimates were: sensitivity=0.45 (95% CI 0.34, 0.61), specificity=0.66 (95% CI 0.53, 0.82), positive likelihood ratio=1.23 (95% CI 0.93, 1.62), negative likelihood ratio=0.84 (95% CI 0.70, 1.01), and diagnostic odds ratio=1.46 (95% CI 0.79, 2.68). The area under the curve was 78% (CI, 57 to 99%). [Conclusion] The results of this systematic review do not show broad and unqualified support for the accuracy of PDs in detecting psychological distress in subacute and chronic LBP.

How the preoperative ultrasound examination and BFI of the cervical lymph nodes modify the therapeutic treatment in patients with papillary thyroid cancer.

BACKGROUND: Ultrasound is considered the best diagnostic method for the detection of metastatic cervical lymph nodes (LNs) in patients with papillary thyroid carcinoma (PTC). According to current guidelines, all patients undergoing thyroidectomy for malignancy should undergo preoperative neck ultrasound of the thyroid and central and lateral neck LNs, followed by fine needle aspiration of suspicious LNs. Cervical LN involvement determenes the extent of surgery. Complete surgical resection disease at the initial operation decreases likelihood of future surgery for recurrent disease and may impact survival. We use a new technique, B-flow imaging (BFI), recently used for evaluation of thyroid nodules, to estimate the presence of BFI twinkling signs (BFI-TS), within metastatic LNs in patients with PTC. METHODS: Between September 2006 and December 2012, 304 patients with known PTC were examined for preoperative sonographic evaluation with gray-scale US, color Doppler US and BFI. Only 157 with at least one metastatic LN were included in our study. All patients included underwent surgery, and the final diagnosis was based on the results of histologic examination of the resected specimens. The following LN characteristics were evaluated: LN shape, abnormal echogenicity, the absent of hilum, calcifications, cystic appearance, peripheral vascularization and the presence of BFI-TS. RESULTS: A total of 767 LNs were analyzed. 329 out of 767 were metastatic, according to the histopathologic findings. BFI-TS, showed 99.5% specificity and 81,5% sensitivity. We detected BFI-TS in 6 metastatic LNs that were negative to the other conventional US features. CONCLUSIONS: Our results indicate that the BFI-TS has a diagnostic accuracy higher than the other conventional sonographic signs. Our findings suggest that BFI can be helpful in the selection of suspicious neck LNs that should be examined at cytologic examination or open biopsy for accurate preoperative staging and individual therapy selection.

Reliability, Validity, and Responsiveness of the Craniocervical Flexion Test in People Who Are Asymptomatic and Patients With Nonspecific Neck Pain: A Systematic Review and Meta-Analysis.

OBJECTIVE: Among the tests designed to evaluate neck neuromuscular function, the craniocervical flexion test (CCFT) assesses the function of the deep cervical flexor muscles (DCFs). The purpose of this study was to conduct a review and meta-analysis of published articles about all measurement properties of the different CCFT versions (CCFT Activation Score [CCFT-AS], CCFT Performance Index [CCFT-PI], CCFT Cumulative Performance Index [CCFT-CPI], and CCFT alternative procedures for measuring activation level (CCFT1) or endurance (CCFT2) in people who were asymptomatic and people with nonspecific neck pain. METHODS: PubMed Central, MEDLINE, CINAHL, Scopus, Web of Science, and Google Scholar were searched from inception to June 30, 2020. Studies were selected if they reported data on reliability, validity, and/or responsiveness of the CCFT in adults who were asymptomatic or who had nonspecific neck pain. Two reviewers independently selected the studies, conducted quality assessment, and extracted the results. All meta-analyses used a random-effects model. RESULTS: Twenty-one studies met the inclusion criteria. The rating of interrater reliability (assessed for CCFT-AS and CCFT-CPI) was positive only for using the test at a group level. The same rating was ascribed to the intrarater reliability of CCFT-AS, CCFT1, and CCFT2, whereas CCFT-PI and CCFT-CPI showed positive intrarater reliability for assessment of individuals as well. CCFT validity was rated as positive for expressly assessing DCF action when measuring DCF activation through electromyography-not through ultrasonography-or craniocervical flexion motion as well as for differentiating patients who were asymptomatic and patients who had nonspecific neck pain (only the AS version). CCFT validity was rated as negative for investigating the CCFT performance correlation with the severity of nonspecific neck pain. CCFT responsiveness was rated as negative. CONCLUSIONS: The CCFT is a potentially useful tool for detecting impairment in DCF control and identifying patients who have nonspecific neck pain and who would benefit from a targeted intervention. However, the limited reliability affects its suitability for that purpose. Further research on the reliability of different CCFT versions in which the raters are thoroughly trained is strongly recommended. IMPACT: The CCFT might help to detect impairment in DCF control and identify patients who have nonspecific neck pain and who would benefit from a targeted intervention. However, the poor reliability of most versions of the test greatly limits its application in clinical practice. Only CCFT-PI and CCFT-CPI seem reliable enough to help in clinical decision-making at the individual level.

Role of Hyperbaric Oxygenation Plus Hypofractionated Stereotactic Radiotherapy in Recurrent High-Grade Glioma.

BACKGROUND: The presence of hypoxic cells in high-grade glioma (HGG) is one of major reasons for failure of local tumour control with radiotherapy (RT). The use of hyperbaric oxygen therapy (HBO) could help to overcome the problem of oxygen deficiency in poorly oxygenated regions of the tumour. We propose an innovative approach to improve the efficacy of hypofractionated stereotactic radiotherapy (HSRT) after HBO (HBO-RT) for the treatment of recurrent HGG (rHGG) and herein report the results of an ad interim analysis. METHODS: We enrolled a preliminary cohort of 9 adult patients (aged >18 years) with a diagnosis of rHGG. HSRT was administered in daily 5-Gy fractions for 3-5 consecutive days a week. Each fraction was delivered up to maximum of 60 minutes after HBO. RESULTS: Median follow-up from re-irradiation was 11.6 months (range: 3.2-11.6 months). The disease control rate (DCR) 3 months after HBO-RT was 55.5% (5 patients). Median progression-free survival (mPFS) for all patients was 5.2 months (95%CI: 1.34-NE), while 3-month and 6-month PFS was 55.5% (95%CI: 20.4-80.4) and 27.7% (95%CI: 4.4-59.1), respectively. Median overall survival (mOS) of HBO-RT was 10.7 months (95% CI: 7.7-NE). No acute or late neurologic toxicity >grade (G)2 was observed in 88.88% of patients. One patient developed G3 radionecrosis. CONCLUSIONS: HSRT delivered after HBO appears to be effective for the treatment of rHGG, it could represent an alternative, with low toxicity, to systemic therapies for patients who cannot or refuse to undergo such treatments.

Effectiveness of physical therapy in addition to occlusal splint in myogenic temporomandibular disorders: protocol of a randomised controlled trial.

INTRODUCTION: Temporomandibular disorders (TMDs) are considered a collection of musculoskeletal conditions involving the masticatory muscles, the temporomandibular joint and associated structures. The myogenous group appears to represent the most frequently diagnosed category. In the context of a multimodal approach, splint therapy and musculoskeletal physiotherapy are often considered as a preferred therapy. The purpose of this study will be to investigate the effects of musculoskeletal physiotherapy combined with occlusal splint and education versus occlusal splint and education alone in the treatment of chronic myogenous TMD on pain and mandibular range of motion. METHODS AND ANALYSIS: All consecutive adults complaining of TMDs presented to the Department of Biomedical and Neuromotor Sciences of the University of Bologna will be considered eligible. Inclusion criteria shall be based on the presence of myogenous TMDs, as diagnosed through clinical examination in reference to the international diagnostic criteria of TMDs. Randomisation, concealed allocation, blinded assessment and intention-to-treat analysis will be employed. The splint therapy will consist of the use of the splint every night and concurrent delivery of an educational programme; the protocol shall have a duration of three consecutive months. The combined musculoskeletal physiotherapy, splint therapy and education will additionally consist of manual therapy techniques and exercise; such protocol shall consist of a duration of three consecutive months, inclusive of 10 sessions for the enhanced elements. All outcome measures will be collected at baseline, after treatment and at a 6 months follow-up. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Independent Ethic Committee in Clinical Research of AUSL Bologna-Italy (47/2018/SPER/AUSLBO). Pursuant to applicable rules,we will obtain informed consent from each participant and collect data anonymously to maintain privacy. Results will be disseminated to clinicians and researchers through peer-reviewed publications and conferences. TRIAL REGISTRATION NUMBER: NCT03726060.

Role of multidetector row computed tomography in the management of mandible traumatic lesions.

Facial injuries are common and must be radiologically evaluated to detect fractures, to determine their morphology and topography, and to assess adjacent soft-tissue damage. Spiral multislice computed tomography is progressively replacing conventional films for mandible traumatic lesions because it reveals the multiplicity of fragments, the degree of dislocation and rotation, and the extent of skull base involvement. Computed tomography is also very useful in the evaluation of condylar fractures, to determine the best choice for surgical treatment, open or close. 3-dimensional (3D) computed tomography images can display condylar fractures, but also all mandibular fractures, accurately and directly, and are very useful for surgeons to select treating methods of condylar fractures. The demonstration by imaging of the involvement of key anatomic structures is essential to classify correctly the trauma and to select the best management.

A new marker for diagnosis of thyroid papillary cancer: B-flow twinkling sign.

OBJECTIVE: The purpose of this study was to correlate the presence and patterns of distribution of B-flow imaging (BFI) twinkling signs within thyroid nodules with the histologic evidence of microcalcifications and the results of the sonographically guided fine-needle aspiration to establish their role in predicting the risk of malignancy. METHODS: Between September 2006 and December 2007, 343 consecutive patients with 479 suspected nodules (maximum diameter > 9 mm) were enrolled in this prospective study. Sonographic and BFI examinations were performed with a commercially available real-time sonography system, and all patients also underwent a cytologic evaluation. Written informed consent was obtained from all patients. Patients with suspicious or malignant cytologic features underwent surgery. RESULTS: On histologic examination, 66 of 479 nodules were malignant (59 papillary thyroid carcinoma, 1 Hürthle cell carcinoma, and 6 follicular carcinoma). All sonographic characteristics, which were potential predictors of thyroid malignancy (microcalcifications, hypoechogenicity, absence of a halo, and a predominantly solid composition), were found in different percentages in both histologically verified malignant and benign nodules. For BFI, pattern 3 (> or = 4 signs and distance > 2 mm) was the most predictive factor for malignancy (specificity, 99.6%; sensitivity, 65.2%), whereas pattern 2 (> or = 4 signs and distance < 2 mm) was a positive factor because it was detected only in benign lesions, with a positive predictive of 0. CONCLUSIONS: Our results indicate that BFI can overcome the limits of the traditional B-mode and color Doppler sonographic features in the diagnosis of thyroid nodules. This technique provides maximum specificity levels both in the case of benign nodules with pattern 2 and in the case of malignant nodules with pattern 3.

Cervical Radiculopathy: Effectiveness of Adding Traction to Physical Therapy-A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background: Cervical radiculopathy (CR) is a common cervical spine disorder. Cervical traction (CT) is a frequently recommended treatment for patients with CR. Purpose: The purpose of this study was to conduct a review and meta-analysis of randomized controlled trials (RCTs) on the effect of CT combined with other physical therapy procedures versus physical therapy procedures alone on pain and disability. Data Sources: Data were obtained from COCHRANE Controlled Trials Register, PubMed, CINAHL, Scopus, ISI Web of Science, and PEDro, from their inception to July 2016. Study Selection: All RCTs on symptomatic adults with CR, without any restriction regarding publication time or language, were considered. Data Extraction: Two reviewers selected the studies, conducted the quality assessment, and extracted the results. Meta-analysis employed a random-effects model. The evidence was assessed using GRADE criteria. Data Synthesis: Five studies met the inclusion criteria. Mechanical traction had a significant effect on pain at short- and intermediate-terms (g = -0.85 [95% CI = -1.63 to -0.06] and g = -1.17 [95% CI = -2.25 to -0.10], respectively) and significant effects on disability at intermediate term (g = -1.05; 95% CI = -1.81 to -0.28). Manual traction had significant effects on pain at short- term (g = -0.85; 95% CI = -1.39 to -0.30). Limitations: The most important limitation of the present work is the lack of homogeneity in CR diagnostic criteria among the included studies. Conclusions: In light of these results, the current literature lends some support to the use of the mechanical and manual traction for CR in addition to other physical therapy procedures for pain reduction, but yielding lesser effects on function/disability.

Congenital muscular dystrophy with muscle inflammation alpha dystroglycan glycosylation defect and no mutation in FKRP gene.

Congenital muscular dystrophies (CMD) are autosomal recessive infantile disorders characterized by dystrophic changes at muscle biopsy and contractures. Central nervous system (CNS) abnormalities associated with mental retardation are often present. We describe a patient affected with muscle weakness, psychomotor developmental delay and normal brain MRI. Muscle biopsy showed complete absence of the alpha-dystroglycan (DG) glycosylated epitope and preservation of alpha-dystroglycan (alpha-DG) protein core. The analysis of FKRP, LARGE, POMT1 and POMGnT1 genes did not show any pathogenic mutations, suggesting that at least another gene may account for CMD with secondary glycosylated alpha-DG deficiency.

A rare case of persistent hypoglossal artery associated with contralateral proximal subclavian stenosis.

The persistent hypoglossal artery is rare vascular anomalies. We report the case of a 50-year old man with right hypoglossal artery, ipsilateral hypoplasic internal carotid artery, associated with left proximal subclavian stenosis with subclavian steal syndrome. Power-Doppler-Ultra-Sonography spectral images obtained after the patient exercised the left arm showed mid-systolic deceleration with retrograde late-systolic velocities. A Computed Tomography Angiography demonstrated a proximal stenosis of the left SA, a mild right ICA hypoplasia and an anomalous artery arising from right ICA at C2-C3 level, entering the cranium via the hypoglossal canal and joining the basilar artery. Usually the presence of PHA may be completely asymptomatic, and detected as an incidental finding by CTA or MRA, but in our case its diagnosis is extremely important because it is often the only vessel supplying blood to the basilar trunk and posterior circulation.

B-flow twinkling sign in preoperative evaluation of cervical lymph nodes in patients with papillary thyroid carcinoma.

Papillary thyroid cancer (PTC) is the most common histologic type of differentiated thyroid cancer. The first site of metastasis is the cervical lymph nodes (LNs). The ultrasonography (US) is the best diagnostic method for the detection of cervical metastatic LNs. We use a new technique, B-flow imaging (BFI), recently used for evaluation of thyroid nodules, to estimate the presence of BFI twinkling signs (BFI-TS), within metastatic LNs in patients with PTC. Two hundred and fifty-two patients with known PTC were examined for preoperative evaluation with conventional US and BFI. Only 83 with at least one metastatic LN were included. All patients included underwent surgery; the final diagnosis was based on the results of histology. The following LN characteristics were evaluated: shape, abnormal echogenicity, absent hilum, calcifications, cystic appearance, peripheral vascularization, and BFI-TS. A total of 604 LNs were analyzed. Of these, 298 were metastatic, according to histopathology. The BFI-TS showed high values of specificity (99.7%) and sensitivity (80.9%). The combination of each conventional US sign with the BF-TS increases the specificity. Our findings suggest that BFI can be helpful in the selection of suspicious neck LNs that should be examined at cytologic examination for accurate preoperative staging and individual therapy selection.

US detection of renal and ureteral calculi in patients with suspected renal colic.

PURPOSE: The purpose of this study was to determine whether the color Doppler twinkling sign could be considered as an additional diagnostic feature of small renal lithiasis (_5mm). METHODS: 181 patients underwent CT scans performed for other pathologies; the images were also analyzed by a radiologists to identify the incidental presence of renal lithiasis equal to or smaller than 5 mm.These patients underwent an abdominal ultrasound examination, including grayscale analysis of the kidneys and color Doppler. Lithiasis were divided into three groups, on the basis of the diagnostic agreement provided by CT and gray scale results. Then, the twinkling sign sensitivity was assessed in the three groups. RESULTS: The twinkling sign was positive in 177 out of 206 lithiasis (86 %) visible on CT, while the grayscale was absolutely positive in 98 out of 206 lithiasis (47.6%) and doubtful positive in 71 out of 206 lithiasis (31%).The twinkling sign was positive in 100% of absolutely positive and doubtful positive lithiasis on bmode, and in 8 out of 31 lithiasis not visible on b-mode. CONCLUSIONS: In the diagnosis of small renal lithiasis, integrating gray-scale with color Doppler may be the most suitable procedure, because the color-Doppler twinkling sign is able to confirm the doubtful diagnosis of renal lithiasis and to detect some lithiasis that are not visible on b-mode.

Repair of orbital floor fractures: our experience and new technical findings.

We report our experience with the repair of the orbital floor fractures and present new technical findings. We evaluated 30 subjects with pure blowout fractures treated at the Department of Maxillofacial Surgery of the Federico II University of Naples, Italy, between 2005 and 2007. A preoperative examination by computed tomography scans provided classification of the orbital floor fractures into small and large fractures by measurement of the bone defect to choose the appropriate reconstructive implant materials, resorbable or nonresorbable. The clinical follow-up has been performed at 1 week, 1 month, 3 months, and 6 months. We observed a resolution of preoperative symptoms. The scar was not evident, and there was an absence of postoperative complications. We concluded that the use of resorbable materials for small orbital floor fractures and nonresorbable materials for large orbital floor fractures offers satisfactory results in both functional and aesthetic considerations. Furthermore, the new technical findings allow standardization of the surgical technique to be more accurate, also reducing the economic costs.

Thyroid B-flow twinkling sign: a new feature of papillary cancer.

BACKGROUND: Microcalcifications (aggregated with psammoma bodies), detected by ultrasound (US), are the most specific feature of papillary thyroid cancer (PTC). Using B-flow imaging (BFI), we identified a new sign (the twinkling sign; BFI-TS) in 'suspect' PTC nodules, which appeared to be generated by microcalcifications. OBJECTIVE: To evaluate whether the BFI-TS was predictive of malignancy, we correlated the BFI-TS with the results of fine needle aspiration cytology and histology. DESIGN: Cross-sectional cohort study from September 2006 to April 2008. SETTING: Department of Radiology and Endocrinology, University of Naples Federico II, and Department of Endocrinology, Second University of Naples. PATIENTS: A total of 306 consecutive patients with 539 thyroid nodules >8 mm in diameter. MAIN OUTCOME MEASURE: US and BFI examinations were performed with the Logiq 9 system (General Electric Company, Milan, Italy); all patients underwent cytological examination. RESULTS: Cytology revealed 455 (84.4%) benign nodules and 84 (15.6%) malignant nodules; the latter were confirmed by postsurgical histological examination (76 cases of PTC, 7 follicular carcinoma, and 1 Hürthle cell carcinoma). All suspect nodules, namely, nodules with potential predictors of thyroid malignancy (e.g., microcalcifications and intra-nodal vascularity), were analyzed by cytology or histology (or both). Of 84, 68 (80.9%) of malignant nodules had >or=4 or more BFI-TSs in at least one scan versus only 12 of 455 (2.6%) of benign lesions. CONCLUSIONS: Our results indicate that the BFI-TS could be a reliable diagnostic technique in the management of suspect thyroid nodules.

Grey-scale analysis allows a quantitative evaluation of thyroid echogenicity in the patients with Hashimoto's thyroiditis.

OBJECTIVE: In the present study we have performed a grey-scale quantitative analysis of thyroid echogenicity in the patients affected by Hashimoto's thyroiditis (HT), obtaining a numerical estimate of the degree of hypoechogenicity associated with the appearance of thyroid dysfunction. MATERIALS AND METHODS: The study group included 89 patients with serum positivity for thyroglobulin (TgAb) and/or peroxidase (TPOAb) antibodies. Ultrasound (US) evaluation of thyroid gland and biochemical assay of serum thyrotropin (TSH), free-thyroxine (FT4) and free-triiodiothyronyne (FT3) were performed in all patients, and in 40 healthy subjects enrolled as control group. Thyroid echogenicity was compared with that of the surrounding neck muscles, using the grey-scale histogram analysis. The echogenicity was expressed in grey-scales (GWE). RESULTS: In HT patients, the mean of thyroid echogenicity was lower when compared to the normal thyroid (61.9 +/- 8.3 GWE vs. 71.9 +/- 3.1 GWE; P = 0.01). In all HT patients the lowest limit of thyroid echo distribution was in the echogenicity range of the surrounding muscle, the overlapping ranging between 3.4% and 95.0% (mean +/- SD 48.4 +/- 20.9%). The extension of like-muscle hypoechogenicity into the thyroid gland was significantly correlated with serum TSH values (r = 0.37; P < 0.001), serum FT4 values (r = -0.60; P < 0.001), and serum TPOAb values (r = 0.31; P = 0.004). Nobody was hypothyroid when the hypoechogenicity was less than 38.0%, whereas hypothyroidism occurred in all cases with hypoechogenicity of more than 68.9%. The receiving operating characteristic curve demonstrated that 48.3% was the best cut-off for identifying hypothyroid patients with sensitivity, specificity and diagnostic accuracy of 88.9%, 86.3% and 87.6%, respectively. CONCLUSIONS: In conclusion, the grey-scale quantitative analysis has provided a measure of thyroid hypoechogenicity associated with the appearance of hypothyroidism during the course of HT. The results of the present study would encourage the application of the computerized grey-scale analysis as complementary tool to US evaluation in the patients affected by HT.
