Purpose This study reviews our experience with deep neck space infections (DNIs) requiring surgical intervention, including cervical necrotizing fasciitis. The aim of the study was to identify predisposing and aggravating factors of the disease and recognize the possible factors that can lead to life-threatening complications and slow down the healing process. Methods We compare the results to previous data from 1985 to 2005 to find possible alterations and changing trends. The characteristics of four lethal cases are described. This retrospective analysis includes patient data from 2004 to 2015 in tertiary referral hospital and in total, 277 patients were found. Results Surgical drainage through a neck opening ± intraoral incision was made in 215 (77.6%) patients, an intraoral incision was only made in 62 patients (22.4%). ICU care was needed in 66 (23.8%) cases. Odontogenic etiology (44.8%) was the most common origin. The most common comorbidity was a psychiatric disorder and/or dementia and occurred in 55 (19.9%) patients. Patients with underlying illnesses were more likely to be admitted to the ICU (p = 0.020), required a longer ICU stay (p = 0.004) and repeated surgery (p = 0.009). Gas formation seemed to be predictive of a more severe course of infection. Early extraction of the odontogenic foci was related to a lower length of stay (LOS) (p = 0.039). Conclusion The annual numbers have risen from 14 to 24 cases per year when compared to previous data. DNIs remain a cause of lethal complications; the mortality was 1.4% and overall complications occurred in 61 (22.0%) patients.

Results of this nationwide study give a general overview of the outcome of unselected patients treated with unified guidelines. Patients with T2 tumors, usually treated with radiotherapy (RT), had a worse prognosis than expected. This patient group warrants further investigation and possibly treatment intensification.

The bringing together of cytopathologists, surgical pathologists, endocrinologists, radiologists, and surgeons at the recent National Cancer Institute Thyroid Fine‐Needle Aspiration State‐of‐the‐Science Conference provided a heady mix for debate and the exchange of ideas. The authors of this commentary predict that the final summary documents from the conference will provide a valuable resource, particularly on cytology‐related matters.

Data obtained from animal and human brain imaging studies indicate that frontal cortex and medial temporal lobe are involved in experiencing and controlling fear and anxiety. We tested the hypothesis that benzodiazepine receptor binding is decreased in the left temporal pole and increased in the right prefrontal area among patients suffering from anxiety. We studied 10 drug-naive female patients with generalized anxiety disorder (GAD) and 10 age-and gendermatched healthy controls with MRI and with SPET by using a new 123 I-labelled specific benzodiazepine receptor radioligand, NNC 13-8241. Blindly analyzed results showed that the benzodiazepine receptor binding of [ 123 I]NNC 13-8241 was significantly decreased in the left temporal pole among patients with GAD when compared with age-and sex-matched healthy controls. This hemispheric asymmetry was studied further with a fractal analysis of the SPET images. The fractal dimension of the left hemispheric benzodiazepine receptor binding in patients with GAD was significantly higher than that of controls (1.28 ± 0.09 and 1.17 ± 0.07, respectively), whereas the intercept was decreased by 43 ± 23% reflecting more homogeneous cerebral benzodiazepine receptor density distribution in patients with GAD. The finding is analogous to the decreased heterogeneity of myocardial blood flow observed in patients with ischemic heart disease. The results are consistent with the general hypothesis that high regional heterogeneity of perfusion, metabolism and receptor density is necessary to maintain adaptation ability in the living organism.
