Risk of Malignancy in FDG-Avid Thyroid Incidentalomas on PET/CT: A Prospective Study.

BACKGROUND: Due to a substantial risk of malignancy, patients with focal FDG-avid thyroid incidentalomas (FFTIs) on PET/CT are in most of Denmark referred to Head and Neck Cancer (HNC) fast track programs. The aim of this study was to determine the risk of malignancy in FFTI managed in a HNC fast track program. METHODS: A prospective cohort study including all patients with FFTI referred to the HNC fast track program, Odense University Hospital between September 1, 2016 and August 31, 2017. Ultrasonography (US) and fine-needle aspiration biopsy (FNAB) were intended to be done in all patients. Nodules with cytology of Bethesda 1, 3, 4, 5, or 6 were planned for surgical removal. RESULTS: A total of 104 patients were included. All patients had US and 101 patients (97%) had FNAB. Forty-two patients had benign cytology classified as Bethesda 2. The remaining 62 patients underwent surgery except from 11 patients, mainly due to comorbidity. The overall risk of malignancy for patients with FFTI referred to our HNC fast track program was calculated to be 24% (23/95) based on patients with unequivocal cytology and/or histology. The only statistically significant US characteristic to predict malignancy was the appearance of irregular margins with a sensitivity of 47% and specificity of 96%. CONCLUSION: The risk of malignancy of FFTIs handled in our HNC fast track program is 24%.

Increased use of total shoulder arthroplasty for osteoarthritis and improved patient-reported outcome in Denmark, 2006-2015: a nationwide cohort study from the Danish Shoulder Arthroplasty Registry.

Background and purpose - Osteoarthritis has become the most common indication for shoulder arthroplasty in Denmark, and the treatment strategies have changed towards the use of anatomical total shoulder arthroplasty and reverse shoulder arthroplasty. We investigated whether changes in the use of arthroplasty types have changed the overall patient-reported outcome from 2006 to 2015. Patients and methods - We included 2,867 shoulder arthroplasties performed for osteoarthritis between 2006 and 2015 and reported to the Danish Shoulder Arthroplasty Registry. The Western Ontario Osteoarthritis of the Shoulder (WOOS) index at 1 year was used as patient-reported outcome. The raw score was converted to a percentage of a maximum score. General linear models were used to analyze differences in WOOS. Results - The proportion of anatomical total shoulder arthroplasty and reverse shoulder arthroplasty increased from 3% and 7% in 2006 to 53% and 27% in 2015. The mean WOOS score was 70 (SD 26) after resurfacing hemiarthroplasties (n = 1,258), 68 (SD 26) after stemmed hemiarthroplasty (n = 500), 82 (SD 23) after anatomical total shoulder arthroplasties (n = 815), and 74 (SD 23) after reverse shoulder arthroplasties (n = 213). During the study period, the overall WOOS score increased with 18 (95% CI 12-22) in the univariate model and 10 (CI 5-15) in the multivariable model, and the WOOS scores for anatomical total shoulder arthroplasty increased by 14 (CI 5-23). Interpretation - We found an increased WOOS score from 2006 to 2015, which was primarily related to a higher proportion of anatomical total shoulder arthroplasty and reverse shoulder arthroplasty towards the end of the study period, and to improved outcome of anatomical total shoulder arthroplasty.

Treatment of Meningiomas Involving the Optic Canal with Endoscopic Transnasal Decompression of the Optic Nerve.

BACKGROUND: Management of patients with optic nerve sheath meningiomas (ONSMs) is controversial and the treatment strategy in this patient group is still up for discussion. Transnasal endoscopic orbital and optic nerve decompression aims to reduce the pressure in the orbit and on the optic nerve and thereby prevent vision loss. This article presents material from 7 cases of transnasal endoscopic orbital decompression. METHODS: The study design is a retrospective cohort study. The aim was to include all patients with a meningioma residing along the nerve sheath and who were operated using endoscopic transnasal decompression of the orbit and if needed the optic canal at Odense University Hospital. Data from the medical records were collected and pre- and postoperative eye examinations were compared. In addition, it was recorded whether there were complications to the procedure and whether additional treatments were given. RESULTS: In total, 4 women and 3 men were included in the study. Four out of 7 patients experienced improvement in vision after the operation. One patient experienced unchanged vision and 2 patients experienced deterioration of vision after surgery. CONCLUSIONS: The current report of 7 patients with ONSM shows promising results for this surgical procedure as 4 out of 7 patients experienced improvement in their vision at follow-up examinations. The 2 patients who experienced deterioration of vision already had severely reduced vision preoperatively, which indicates that surgery should be considered before the vision becomes significantly reduced.

The Danish Shoulder Arthroplasty Registry: clinical outcome and short-term survival of 2,137 primary shoulder replacements.

The Danish Shoulder Arthroplasty Registry (DSR) was established in 2004. Data are reported electronically by the surgeons. Patient-reported outcome is collected 10-14 months postoperatively using the Western Ontario osteoarthritis of the shoulder index (WOOS). 2,137 primary shoulder arthroplasties (70% women) were reported to the registry between January 2006 and December 2008. Mean age at surgery was 69 years (SD 12). The most common indications were a displaced proximal humeral fracture (54%) or osteoarthritis (30%). 61% were stemmed hemiarthroplasties, 28% resurfacing hemiarthroplasties, 8% reverse shoulder arthroplasties, and 3% total arthroplasties. Median WOOS was 59% (IQR: 37-82). 5% had been revised by the end of June 2010. The most frequent indications for revision were dislocation or glenoid attrition.

Endonasal Endoscopic Approach for Minimally Invasive Orbital Decompression in Nonthyroid Proptosis-A Scoping Review.

OBJECTIVE: The endoscopic endonasal approach (EEA) was originally performed to treat thyroid orbitopathy and proptosis. Since then, this approach also has been used to treat other causes of proptosis. This review systematically identifies surgical outcome and complication rates in patients without thyroid proptosis who underwent endoscopic endonasal orbital decompression. METHODS: Databases were searched using the following search terms: orbital disease, surgical decompression, and endoscopic endonasal approach. Two independent reviewers screened all abstracts and titles for relevance and all articles passing this screen were subjected to full-text review. To assess risk of bias, we used ROBINS-I (Risk Of Bias in Non-randomized Studies-of Interventions). RESULTS: Eight studies with a total of 74 patients with nonthyroid proptosis were included. Pre- and postoperative eye examination was performed in all studies, but the extent of examination was varying. With a mean age of 35.7 years, most patients were adolescent, and most pathologies induced unilateral proptosis Complications to EEA for orbital decompression were transient diplopia (5 patients/6.8%), transient facial dysesthesia (2 patients/2.7%), ptosis (1 patient/1.4%), infarction (1 patient/1.4%), sinus obstruction (1 patient/1.4%), and enophtalmos (1 patient/1.4%). The authors reported successful reduction of proptosis in all but 2 patients (97.2%), and only 2 authors reported a need for secondary decompression. CONCLUSIONS: Medial orbital decompression using EEA is a feasible approach for orbital decompression in patients with nonthyroid proptosis. While being comparable in primary outcome to transorbital approaches, the EEA seems superior in terms of complication rates.

A method for implementation of nutritional therapy in hospitals.

BACKGROUND AND AIMS: Many barriers make implementation of nutritional therapy difficult in hospitals. In this study we investigated whether, a targeted plan made by the staff in different departments could improve nutritional treatment within selected quality goals based on the ESPEN screening guidelines. METHODS: The project was carried out as a continuous quality improvement project. Four different specialities participated in the study with a nutrition team of both doctors, nurses, and a dietician, and included the following methods: (1) Pre-measurement: assessment of quality goals prior to study including the use of screening of nutritional risk (NRS-2002), whether a nutrition plan was made, and monitoring was documented in the records. (2) INTERVENTION: multidisciplinary meeting for the ward staff using a PC-based meeting system for detecting barriers in the department concerning nutrition, elaboration of an action plan and implementation of the plan. (3) Re-measurement: as in (1) based on information from records and patient interviews, and an evaluation based on focus group interview with the staff. Patients who gave informed consent to participate in the study (>14 years) were included consecutively. Mann-Whitney and Kruskal-Wallis test was used for ordinal data, and Pearson chi(2) test for nominative data. P values <0.05 were considered significant. The study was performed in accordance with the Research Ethics Committee. RESULTS: In this study 141/122 patients were included before/after the implementation period with a mean weight loss within the last 3 months of 6.2 and 5.2 kg, respectively. Before the study we found that BMI was not measured. More than half of the patients had a weight loss within the last 3 months, and 40% had a weight loss during hospitalization, and this was not documented in the records. About 75% had a food intake less than normal within the last week, and nearly one-third were at a severe nutritional risk, and only 33% of these had a nutrition plan, and 18% a plan for monitoring. Barriers concerning nutrition included low priority, no focus, no routine or established procedures, and insufficient knowledge, lack of quality and choice of menus, and lack of support from general manager of the hospital. The staff introduced individually targeted procedures including assigning of responsibility, a nutrition record, electronic calculator of energy intake, upgrading of the dieticians and special diets, communication, and educational programs. A great consistency existed between barriers for targeted nutrition effort and ideas for improvement of the quality goals between the different departments. Quality assessment after study showed an overall significant improvement of the selected quality goals. CONCLUSION: The introduction of a new method for implementation of nutritional therapy according to ESPEN screening guidelines seems to improve nutritional therapy in hospitals. The method included assessment of quality goals, identification of barriers and individual targeted plans for each department followed by an evaluation process. The model has to be refined further with relevant clinical endpoints.

[Odontogenic myxoma of the maxilla in a three-year-old boy].

A three-year-old boy presented with a painless mass in the nasolabial fold and ipsilateral increased tearing. A diagnosis of odontogenic myxoma (OM) was established by biopsy, and the tumour was excised using a combined oral and transconjuctival approach. In small children OM occurs almost exclusively in the maxilla. Orbital involvement is very rare, and to our knowledge reconstruction with a Medpore sheet has not previously been reported. At post-operative follow-up normal eye function and an excellent cosmetic result was observed. OM should be considered in a midfacial mass.

Translation and validation of the Western Ontario Osteoarthritis of the Shoulder (WOOS) index - the Danish version.

BACKGROUND AND PURPOSE: The Western Ontario Osteoarthritis of the Shoulder (WOOS) index is a patient-reported, disease-specific questionnaire for the measurement of the quality-of-life in patients with osteoarthritis. The purpose of this study was to describe the process used to translate the WOOS into Danish and to test the translation in a Danish population, in terms of validity, reliability, and responsiveness. MATERIAL AND METHODS: The translation of the WOOS was done according to international standardized guidelines. The psychometric properties were tested in 20 consecutive patients. The eligibility criteria were: a diagnosis of osteoarthritis without symptomatic rotator cuff pathology and treated with primary shoulder replacement. Patients were excluded only in the case of other pathology of the upper extremity or in the case of cognitive or linguistic impairment compromising the ability to complete the questionnaires. RESULTS: The Pearson's correlation coefficient between the WOOS and the Constant-Murley score (CMS), preoperatively was 0.62 (P = 0.004) and the correlation between the changes of score for the WOOS and CMS was 0.73 (P < 0.001). The correlation coefficient between the WOOS and the CMS, SF-36, and the Oxford Shoulder Score postoperatively was 0.82 (P < 0.001), 0.48 (P = 0.03), and 0.82 (P < 0.001), respectively. There were no floor and ceiling effects. The Cronbach's alpha was 0.98. The intraclass correlation coefficient between test and retest was 0.96. The standardized response mean was 1.41, and effect size was 2.32. CONCLUSION: We have shown that the Danish version of the WOOS, translated according to international standardized guidelines, has substantial statistical and clinical psychometric properties at the same level as was described for the original version.

[Assessment of thyroplasty for vocal fold paralysis]. / Monitorering af operativ behandling af stemmebåndsparese ved tyroplastik.

INTRODUCTION: Thyroplasty with silicone rubber implantation is a surgical procedure for treatment of patients with vocal fold paralysis. The aim of the present study was to evaluate the outcome of the operation and to monitor which of the analyses were the more beneficial. MATERIAL AND METHODS: Twenty consecutive patients were enrolled in the study. To assess the treatment, videostroboscopic evaluation was performed and maximal phonation time was measured. A phonetogram was recorded to evaluate voice capacity and intensity, and a voice quality analysis was performed using the Multi-Dimensional Voice Program. Furthermore, patients answered the Voice Handicap Index (VHI) questionnaire. RESULTS: The capacity and intensity of the voice were significantly increased with an improvement of the highest intensity of 13 dB. The capacity of the voice was increased more than 2.5 times. The voice quality was improved significantly as measured by the jitter percentage, shimmer percentage and voice turbulence index. The VHI was decreased by 40, from a mean preoperative value of 82. A total of 90% of patients were satisfied. CONCLUSION: Besides videostroboscopy, a phonetogram is the most important analysis because it offers a quantitative measure of the voice capacity and intensity, which are the major problems experienced by patients with vocal fold paralysis. Used together, these tools are highly instrumental in guiding the patient's choice of surgery or no surgery.

[Introduction to ultrasonography of lymph nodes of the neck]. / Introduktion til ultralydsskanning af halsens lymfeknuder.

This is a short introduction to ultrasonography of lymph nodes of the neck in patients with malignant melanoma, head & neck cancer and skin cancer. Systematic examination and knowledge of the neck's anatomy and the types of neck dissections lie at the root of successful neck ultrasonography. The shape and volume are evaluated by B-mode and greyscale ultrasonography. Doppler ultrasonography can be used to distinguish between solid structures and vessels. Ultrasonography is well-suited for evaluation of regional lymph node status.

[Juvenile angiofibroma]. / Juvenile angiofibromer.

Juvenile angiofibroma is a rare, benign, rich vascular tumor, and approximately one new case is diagnosed in Denmark each year. It sits in the foramen sphenopalatinum and occurs in boys from 14 to 25 years of age. The most frequent initial symptoms are nasal obstruction and epistaxis. Through the years, the treatment of juvenile angiofibroma has included many methods, including surgical excision, electrocoagulation, interstitial or external radiation therapy, cryosurgery, hormone administration and chemotherapy. Radiation, chemotherapy and surgery have proven to be the most effective treatments. The most serious complication has been preoperative bleeding, but since the introduction of preoperative particle embolization the blood loss has been greatly reduced. Today, surgery preceded by embolization is the primary standard treatment. It is important to diagnose the tumor early, when radical surgery is easier and the frequency of recurrence is lower.

[Treatment of juvenile angiofibroma with particle embolization and endoscopic surgery]. / Behandling af juvenile angiofibromer med partikelembolisering og endoskopisk kirurgi.

INTRODUCTION: Juvenile angiofibroma is a benign, rich vascular nasal tumor, and the biggest complication in surgery is the great loss of blood. Since 1997, Odense University Hospital (OUH) has used preoperative particle embolization and endoscopic surgery to combat this problem. MATERIALS AND METHODS: A retrospective review of the eight patients who have been treated since 1997 was done. The embolization, which was carried out in the radiotherapy department, was done with polyvinyl alcohol particles in the vessels that supply the tumor. The operation was then performed in the ear, nose and throat department of OUH. The tumor was removed endoscopically in all cases in which it was possible. RESULTS: All eight patients were embolized preoperatively. The average preoperative bleeding was 375 ml, a little less when endoscopic access was possible. This is in agreement with the literature and may be considered to be satisfactory. DISCUSSION: Endovascular embolization of juvenile angiofibromas followed by endoscopic surgery is considered to be the preferred treatment method today.
