RESUMO
INTRODUCTION: Currently, there is limited literature on reconstructive trends for inpatient head and neck skin cancer. Rather, studies have focused primarily on patients treated on an outpatient basis. To gain a better understanding of the effect that reconstructive correction of complex skin cancer defects has on the healthcare system, we examined the existing incidence and reconstructive trends of head and neck melanoma and nonmelanoma skin cancer (NMSC) in the inpatient setting. METHOD: We performed the analysis of the Healthcare Cost and Utilization Project Nationwide Inpatient Sample Database (NIS) for the years 2012-2014 of the United States (US). Adults diagnosed with melanoma skin cancer or NMSC of the head and neck region were included. Patient characteristics, reconstructive modality, surgical specifics, and outcomes were retrieved. Trends with time for reconstruction techniques were analyzed. RESULTS: In total, 41,185 patients with a diagnosis of skin malignancy were identified, of whom 5,480 (13.3%) underwent reconstruction. Most patients were white (90.0%), male (71.6%), and had a diagnosis of NMSC (79.2%). An increase in flap reconstruction (p < 0.001) was observed. After population adjustment, the highest incidence of skin malignancy was found in the Northeast. CONCLUSION: There has been a trending increase in inpatient NMSC and melanoma skin cancer of the head and neck region, correlating to an increase in the reconstructive procedures performed, and greater cost burden. Resources may be allocated toward early identification and treatment for skin cancer to help control the current rise in complex skin cancer cases necessitating inpatient admission.

In the diagnostic work-up of Madelung deformity conventional radiographic imaging is often used, assessing the three-dimensional deformity in a two-dimensional manner. A three-dimensional approach could expand our understanding of Madelung deformity's complex wrist anatomy, while removing inter- and intra-rater differences. We measured previous two-dimensional-based and newly developed three-dimensional-based parameters in 18 patients with Madelung deformity (28 wrists) and 35 healthy participants (56 wrists). Madelung deformity wrists have increased levels of ulnar tilt, lunate subsidence, lunate fossa angle, and palmar carpal displacement. The lunate fossa is more concave and irregular, and angles between scaphoid, lunate, and triquetral bones are decreased. These findings validate the underlying principles of current two-dimensional criteria and reveal previously unknown anatomical abnormalities by utilizing novel three-dimensional parameters to quantify the radiocarpal joint.

Purpose To present an updated prevalence estimate for incidental findings on brain magnetic resonance (MR) images and provide information on clinical relevance, including natural course, over a period of up to 9 years. Materials and Methods This study was approved by the institutional review board and all participants gave informed consent. In a prospective population-based setting, structural brain MR imaging was performed in 5800 participants (mean age, 64.9 years; 3194 women [55.1%]). Trained reviewers recorded abnormalities, which were subsequently evaluated by neuroradiologists. The prevalence with 95% confidence interval (CI) of incidental findings was determined, and clinical management of findings that required the attention of a medical specialist was followed. Follow-up imaging in the study context provided information on the natural course of findings that were not referred. Results In 549 of 5800 participants (9.5% [95% CI: 8.7%, 10.3%]), incidental findings were found, of which meningiomas (143 of 5800; 2.5% [95% CI: 2.1%, 2.9%]) and cerebral aneurysms (134 of 5800; 2.3% [95% CI: 2.0%, 2.7%]) were most common. A total of 188 participants were referred to medical specialists for incidental findings (3.2% [95% CI: 2.8%, 3.7%]). Of these, 144 (76.6% [95% CI: 70.1%, 82.1%]) either underwent a wait-and-see policy or were discharged after the initial clinical visit. The majority of meningiomas and virtually all aneurysms not referred or referred but untreated remained stable in size during follow-up. Conclusion Incidental findings at brain MR imaging that necessitate further diagnostic evaluation occur in over 3% of the general middle-aged and elderly population, but are mostly without direct clinical consequences. © RSNA, 2016.
