The detection of pathological parathyroid glands is facilitated by identifying vascular features on ultrasound: the potential benefit of a low-frequency vascular probe.

Purpose: To evaluate the potential benefit of adding a low frequency vascular probe to the conventional pre-operative ultrasound examination of patients with primary hyperparathyroidism.

Methods: A prospective cohort of 136 patients with primary hyperparathyroidism underwent a conventional ultrasound examination of the neck with a high frequency ( > 10 MHz) linear ultrasound probe, followed by an add-on examination with a low frequency vascular probe. For each ultrasound probe, and for every potential parathyroid lesion, the presence of a feeding vessel, a polar placement of the feeding vessel, and the presence of a vascular arch was recorded.

Evaluation of Surgeon-Performed Ultrasonography With or Without Contrast Enhancement vs Scintigraphy in Patients With Primary Hyperparathyroidism.

Importance: Scintigraphy and ultrasonography are common imaging modalities for the preoperative localization of enlarged parathyroid glands in primary hyperparathyroidism. When comparing the 2 modalities, the benefits of ultrasonography in terms of convenience, patient comfort, duration, cost, and lack of radiation should be taken into account.

Objective: To investigate whether surgeon-performed ultrasonography, with or without contrast-enhanced ultrasonography (CEUS), is noninferior to scintigraphy for localizing pathological parathyroid glands in patients with primary hyperparathyroidism.

Head-to-Head Comparison of Tc-99m-sestamibi SPECT/CT and C-11-L-Methionin PET/CT in Parathyroid Scanning Before Operation for Primary Hyperparathyroidism.

Purpose: The preferred nuclear medicine method for identification of hyperfunctioning parathyroid glands in hyperparathyroidism (HPT) develops continuously in relation to the technological progress. Diagnostic methods based on PET/CT have during recent years evolved with new tracer possibilities competing with traditional scintigraphic methods. This investigation is a head-to-head comparison of Tc-99m-sestamibi SPECT/CT gamma camera scintigraphy (sestamibi SPECT/CT) and C-11-L-methionin PET/CT imaging (methionine PET/CT) for preoperative identification of hyperfunctioning parathyroid glands.

This is a classic case report of a rare giant fibrovascular polyp (GFP) of the oesophagus in a 50-year-old male patient, who two years prior had regurgitated the polyp and swallowed it again. He only sought medical professionals after losing 25 kg and having severe dysphagia. The GFP, weight 520 g and size 21 × 9 × 7 cm, was removed in toto with a cervical excision following intraluminal marking of the base of the polyp during oesophagoscopy.

Protocol for a randomised clinical trial of transoral ultrasound versus standard of care in the diagnosis of peritonsillar abscess.

Introduction: Peritonsillar infection is a common complication to acute tonsillitis in younger adults. If peritonsillar cellulitis progresses to a peritonsillar abscess (PTA), the primary treatment is surgical drainage. But distinguishing cellulitis from PTA on a standard clinical examination is difficult.

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.

Intranasal corticosteroids compared with oral antihistamines in allergic rhinitis: A systematic review and meta-analysis.

Background: Intranasal corticosteroids (INS) (corticosteroid nasal sprays) and oral antihistamines (OA) are two of the most common treatments for patients with allergic rhinitis (AR). To our knowledge, there are no systematic reviews on this topic including trials published after 2007.

Objective: To compare INS with nonsedating OAs as treatments for AR.

Risk factors for treatment failure in surgery for primary hyperparathyroidism: the impact of change in surgical strategy and training procedures.

Surgery for primary hyperparathyroidism (pHPT) has a high cure-rate and few complications. Preoperative localization procedures have permitted a dramatic shift from routine bilateral exploration to focused, minimally invasive procedures. At Odense University Hospital, Denmark, the introduction of focused surgery was combined with training of new surgeons.

Risk factors for recurrent nerve palsy after thyroid surgery: a national study of patients treated at Danish departments of ENT Head and Neck Surgery.

Recurrent laryngeal nerve (RLN) injury is a well-known and serious complication to thyroid surgery. The objective was to estimate the frequency of post-thyroidectomy RLN palsy and to identify possible risk factors. Based on the Danish national thyroid surgery database, 6,859 patients treated with thyroid surgery from 1 January 2001 to the 31 December 2008 at the Danish departments of ENT-HNS were analyzed.

Squamous cell carcinoma of the nasal vestibule 1993-2002: a nationwide retrospective study from DAHANCA.

Background: A retrospective nationwide study of cancer of the nasal vestibule was conducted to evaluate classification systems and prognostic factors for treatment outcome.

Methods: Patients treated between 1993 and 2002 at head and neck oncology centers in Denmark were included.

Results: The 5-year results were locoregional control 67%, overall survival 50%, cancer-specific survival 74%.

Post-thyroidectomy hemorrhage: a national study of patients treated at the Danish departments of ENT Head and Neck Surgery.

As bleeding in the neck region is a potentially life-threatening complication, we found it imperative to concretize the frequency and to identify possible reasons for this complication. A national database of all thyroid surgery performed inside the specialty of ENT Head and Neck Surgery (THYKIR) was established in January 2001. This nationwide cohort study represents 5,490 patients included until December 2007.

Cancer of the external auditory canal and middle ear in Denmark from 1992 to 2001.

Background: In the context of the Danish Head and Neck Cancer Group, nationwide material from 1992-2001 was analyzed to study the extent and nature of the disease, evaluate treatment, compare staging systems, and examine prognosis and survival.

Methods: Review of 68 consecutive cases: 47 squamous cell carcinoma, 10 basal cell carcinoma, and 11 other histologies. Moody (modified Pittsburgh) stages were T1 (26), T2 (9), T3 (8), T4 (23), Tx (2).
