Y. S. Elshot, D. C. K. S. Tio, A. S. E. Haersma‐de With, W. Ouwerkerk, more

Journal of the European Academy of Dermatology and Venereology > 37 > 5 > 871 - 883

Because of an increased risk of local recurrence following surgical treatment of lentigo maligna (melanoma) (LM/LMM), the optimal surgical technique is still a matter of debate. We aimed to evaluate the effect of different surgical techniques and reflectance confocal microscopy (RCM) on local recurrence and survival outcomes. We searched MEDLINE, Embase and PubMed databases through 20 May 2022. Randomized...

Lisanne P. Zijlker, Max Bakker, Bernies Hiel, Annemarie Bruining, more

Journal of Surgical Oncology > 127 > 5 > 841 - 847

Background Merkel cell carcinoma (MCC) is a cutaneous tumor with a high tendency to metastasize, and a significant proportion of patients have metastases at first presentation. This study aims to determine the value of baseline ultrasound (US) and ¹⁸fluorodeoxyglucose‐positron emission tomography/computed tomography (¹⁸FDG‐PET/CT) imaging in both patients with clinically localized MCC (Stage I/II)...

Viola Franke, Max F. Madu, Carolien Bierman, Willem M. C. Klop, more

Journal of Surgical Oncology > 122 > 5 > 964 - 972

Background With the approval of adjuvant therapy for stage III melanoma, accurate staging is more important than ever. Sentinel node biopsy (SNB) is an accurate staging tool, yet the presence of capsular nevi (CN) can lead to a false‐positive diagnosis. Patients and Methods Retrospective analysis of the American Joint Committee on Cancer 7th edition stage IIIA melanoma patients who were treated...

Martine Hendriksma, Yda van Loon, W. Martin C. Klop, Marieke M. Hakkesteegt, more

European Archives of Oto-Rhino-Laryngology > 2019 > 276 > 3 > 805-814

Purpose Longitudinal studies in laryngeal cancer can provide clinicians information about short-term and long-term functional outcomes, like quality of life (QoL) and voice outcome. This information is important when counseling patients or choosing a primary treatment modality. The present study assessed long-term (2 years) QoL and voice outcome in patients with extended T1 and limited T2 glottic...

I. J. A. Bruin, C. Klop, C. E. Wyers, J. A. Overbeek, more

Osteoporosis International > 2019 > 30 > 3 > 573-581

Summary In the first year, after an osteoporotic fracture of a hip, forearm, upper arm, or spine, the dispensing rates of antidepressants and benzodiazepines increased significantly. After those fractures, recent and past use of antidepressants and benzodiazepines was associated with increased all-cause mortality; current use was not associated with mortality risk. Introduction It remains unclear...

Osteoporosis International > 2018 > 29 > 11 > 2477-2485

Summary This is the first study to examine the association between antidepressant and benzodiazepine use following a MOF and risk of subsequent fracture in those 65+. Using national data, drug use following MOF showed that the 1-year fully adjusted risk of subsequent MOF in those on antidepressants was more than doubled. Introduction We evaluated the association between the use of antidepressants...

Pieter D. Veij Mestdagh, Marcel C. J. Jonker, Wouter V. Vogel, Willem H. Schreuder, more

European Archives of Oto-Rhino-Laryngology > 2018 > 275 > 8 > 2135-2144

Purpose To investigate the feasibility of lymph drainage mapping (LDM) using SPECT/CT to help select head and neck cancer (HNSCC) patients for unilateral elective neck irradiation (ENI). Patients with lateralized HNSCC treated with radiotherapy routinely undergo bilateral ENI, despite the incidence of contralateral regional failure being relatively low even after unilateral ENI. We hypothesized that...

The best of both worlds: a hybrid approach for optimal pre- and intraoperative identification of sentinel lymph nodes

G. H. KleinJan, E. Werkhoven, N. S. Berg, M. B. Karakullukcu, more

European Journal of Nuclear Medicine and Molecular Imaging > 2018 > 45 > 11 > 1915-1925

Purpose Hybrid image-guided surgery technologies such as combined radio- and fluorescence-guidance are increasingly gaining interest, but their added value still needs to be proven. In order to evaluate if and how fluorescence-guidance can help realize improvements beyond the current state-of-the-art in sentinel node (SN) biopsy procedures, use of the hybrid tracer indocyanine green (ICG)-^99mTc-nancolloid...

Gijs H. KleinJan, Baris Karakullukçu, W. Martin C. Klop, Thijs Engelen, more

EJNMMI Research > 2017 > 7 > 1 > 1-8

Background Intraoperative sentinel node (SN) identification in patients with head-and-neck malignancies can be challenging due to unexpected drainage patterns and anatomical complexity. Here, intraoperative navigation-based guidance technologies may provide outcome. In this study, gamma camera-based freehandSPECT was evaluated in combination with the hybrid tracer ICG-^99mTc-nanocolloid. Materials...

Clinical Anatomy > 30 > 6 > 799 - 804

The aim of this study was to determine whether effects of repetitive freeze‐thaw cycles, with various thawing temperatures, on human muscle tissue can be quantified using postmortem computed tomography (PMCT) technology. An additional objective was to determine the preferred thawing temperature for muscle tissue in this study. Human cadaver upper extremities were divided into two different thawing...
