Background:The most common complication after breast cancer surgery is seroma formation. It is a source of significant morbidity and discomfort. Many articles have been published describing risk factors and preventive measures. The aim of this paper is to provide a systematic review of studies and reports on risk factors and preventive measures. Surgery lies at the core of seroma formation; therefore focus will be placed on surgical ways of reducing seroma. Methods: A computer assisted medline search was carried out, followed by manual retrieval of relevant articles found in the reference listings of original articles. Results: 136 relevant articles were reviewed. Though the level of evidence remain varied several factors,type of dissection, tools with wich dissection is carried out, reduction of dead space, suction drainage, use of fibrin glue and octreotide usage, have been found to correlate with seroma formation and have been shown to significantly reduce seroma rates. Conclusion: Seroma formation after breast cancer surgery can not be avoided at present. There are however several methods to minimize seroma and associated morbidity. Future research should be directed toward the best ways of reducing seroma by combining proven methods.

BackgroundThe clavicle hook plate achieves like most other operative techniques, a high percentage of union and a low percentage of complications however concerns about long term complications still exist, particularly the involvement of the acromioclavicular joint.MethodsTo evaluate the results and long term effects in use of this plate we performed a retrospective analysis with a mean follow up of 65 months (5.4 years) of 28 consecutive patients with acute displaced lateral clavicle fractures, treated with the clavicle hook plate.ResultsShort term functional results in all patients were good to excellent. All but one patient had a united fracture (96%). Nine patients (32%) developed impingement symptoms and in 7 patients (25%) subacromial osteolysis was found. These findings resolved after plate removal. Twenty-four patients were re-evaluated at a mean follow-up period of 5.4 years. The Constant-Murley score was 97 and the DASH score was 3.5. Four patients (14%) developed acromioclavicular joint arthrosis of which one was symptomatic. Three patients (11%) had extra articular ossifications of which one was symptomatic. There was no relation between the impingement symptoms, subacromial osteolysis and development of acromioclavicular joint arthrosis or extra articular ossifications.ConclusionsThe clavicle hook plate is a good primary treatment option for the acute displaced lateral clavicle fracture with few complications. At mid term the results are excellent and no long term complications can be addressed to the use of the plate.

In patients with acute bacterial rhinosinusitis severe orbital and intracranial complications can occur. This review will illustrate the anatomic relationship between the paranasal sinuses and the orbital and intracranial compartments. Subsequently, the spectrum of orbital and intracranial complications of rhinosinusitis and related imaging findings will be discussed and illustrated by case material from daily practice.Teaching Points• Acute bacterial rhinosinusitis can cause severe orbital and intracranial complications.• If orbital or intracranial complications are suspected, cross-sectional imaging is mandatory.• Infection can spread from the ethmoid sinus to the orbit through the lamina papyracea.• Frontal sinusitis can spread intracranially through dehiscences or osteomyelitis.• Radiologists must recognize imaging findings of complications of acute bacterial rhinosinusitis.

In HNSCC, positive HPV status correlates with low mean apparent diffusion coefficient. The favorable prognostic value of low pretreatment apparent diffusion coefficient might be partially attributed to patients with a positive HPV status. © 2015 Wiley Periodicals, Inc. Head Neck 38: E613-E618, 2016.
