- Background: A successful clinical result is reported in 75% to 85% of impingement patients after arthroscopic subacromial decompression. The result is maintained over time, but few studies have investigated the integrity of the rotator cuff in these patients. Materials and methods: Using ultrasonography, we examined the integrity of the rotator cuff in 70 patients 15 years after arthroscopic subacromial decompression. All patients had an intact rotator cuff at the index procedure. Results: Tendons were still intact in 57 patients (82%), 10 (14%) had partial-thickness tears, and 3 (4%) had full-thickness tears. Discussion: The total number of 18% tears (partial and full thickness) in this study, including patients clinically diagnosed with subacromial impingement at a mean age of 60 years, is unexpectedly low compared with 40% degenerative tears reported in asymptomatic adults of the same age. Conclusion: Arthroscopic subacromial decompression seems to reduce the prevalence of rotator cuff tears in impingement patients. This appears attributable to elimination of extrinsic factors such as mechanical wear and bursitis. The potential effect of surgery on intrinsic cuff degeneration is unknown, but intrinsic factors may explain tears still developing despite decompression.

- Background: Depth of invasion (DOI) is important for the T-classification of squamous cell carcinoma of the oral tongue (SCCOT) and incorporated in the TNM 8 classification of oral cavity cancer. To determine DOI clinical palpation is performed, but the preferred radiological modality remains controversial. The aim of this study was to investigate the assessment of DOI using ultrasound (US-DOI).Methods: The DOI was assessed in 40 patients with T1-T3 SCCOT by ultrasound, palpation, computed tomography and magnetic resonance imaging (MRI). Histopathological DOI (H-DOI) was gold standard. Bland-Altman analysis was used to compare mean difference and 95% limits of agreement (LOA). Results The mean difference of US-DOI was -0.5 mm (95% LOA -4.9-4.0) compared to H-DOI and the mean difference for MRI was 3.9 mm (95% LOA -2.3-10.2). In the subgroup analysis of cT1-T2 the US-DOI mean difference was 0.1 mm and the 95% LOA limits -2.5-2.7.Conclusions: Ultrasound seems to be the most accurate method to assess DOI in T1-T2 SCCOT. MRI overestimates DOI and cannot assess a substantial proportion of the tumors. Level of Evidence 2c.

- BACKGROUND: In surgical resection of squamous cell carcinoma of the oral tongue (SCCOT), achieving clear margins is important for prognosis. Insufficient histopathological margins are common, particularly deep margins.AIMS/OBJECTIVES: The aim of the present study was to determine whether ultrasound (US)-assisted resection could decrease the proportion of insufficient histopathological deep margins in SCCOT.MATERIAL AND METHODS: 34 patients with SCCOT undergoing US-assisted resection (study group) were compared to 76 whose resections were performed without US (conventional group). Outcome measures were insufficient deep histopathological resection margins and mean difference in deep margins.RESULTS: Insufficient deep resection margins (<5.0 mm) were seen in 8 of 34 (23.5%) in the study group, compared to 31 of 76 (40.8%) in the conventional group, unadjusted RR 0.58 [95% CI 0.30-1.12; p = .11], adjusted RR 0.82 [95% CI 0.35-1.92; p = .64]. Unadjusted mean difference was 1.4 mm (95% CI 0.1-2.7, p = .04), adjusted mean difference 1.1 mm (95% CI -2.7 to 0.5, p = .19).CONCLUSIONS: Intraoperative US can visualize the deep resection margins in T1/T2 SCCOT. US-assisted resection seems to decrease the number of insufficient histopathological deep margins, though the results are not statistically significant. Comparatively good results in the conventional group is one explanation for the lack of significance.CLINICALTRIALS.GOV ID: NCT04059861.

Pain and fear in connection to orthodontic extractions of deciduous canines.

- BACKGROUND: Interceptive extractions of deciduous canines are, from a patient perspective, poorly investigated. AIMS: To describe pain, discomfort, and dental fear in connection to extractions of the deciduous canines, indicated as an orthodontic treatment procedure. DESIGN: Thirty-two Swedish children aged 7-9 years had all four deciduous canines extracted over three occasions. The children rated procedural and postoperative pain on visual analogue scales. Acceptance of injections and extractions was assessed by the treating dentists. Analgesic consumption and recovery time for drinking and eating was reported by parents. Dental fear was assessed using the Children's Fear Survey Schedule questionnaire. RESULTS: Procedural pain showed low median levels, although some individuals reported high values. Boys reported significantly more pain at appointments when two (as opposed to one) canines were extracted. Postoperative pain levels were low and use of analgesics sparse. Dental fear paralleled norm values and did not increase from pre- to post-extraction. CONCLUSIONS: Pain management routines during extractions of this kind should be revised. Single tooth extractions seem to be preferable to extractions of two canines at the same appointment. Extraction of four deciduous canines should not cause major postoperative inconvenience; these extractions neither triggered nor increased dental fear.
