Regional versus local wind speed and direction at a narrow beach with a high and steep foredune.

Dune growth and post-storm recovery of foredune systems is predominantly determined by the aeolian sand transport through the beach-dune interface. Potential sand transport rates, estimated with empirical transport equations using regionally representative wind conditions, are generally too high. This positive bias might be, at least partly, due to the effect of the beach and foredune topography on the regional airflow.

Evaluation of Staphylococcus aureus Eradication Therapy in Vascular Surgery.

Introduction: Surgical site infections (SSI) are a serious complication in vascular surgery which may lead to severe morbidity and mortality. Staphylococcus aureus nasal carriage is associated with increased risk for development of SSIs in central vascular surgery. The risk for SSI can be reduced by perioperative eradication of S.

Review: Quality of life in lower limb peripheral vascular surgery.

Purpose: Vascular intervention studies generally consider patency and limb salvage as primary outcomes. However, quality of life is increasingly considered an important patient-oriented outcome measurement of vascular interventions. Existing literature was analyzed to determine the effect of different treatments on quality of life for patients suffering from either claudication or critical limb ischemia.

The current position of precuffed expanded polytetrafluoroethylene bypass grafts in peripheral vascular surgery.

Objective: Long-term results of precuffed expanded polytetrafluoroethylene (ePTFE) grafts used for peripheral bypass surgery are lacking. The aim of this study was to obtain the long-term outcomes of precuffed ePTFE grafts compared with autologous saphenous vein (ASV) grafts used in patients with peripheral arterial disease (PAD).

Methods: A single-institution retrospective study of precuffed ePTFE and ASV graft performances in patients with PAD was undertaken between January 2004 and December 2012.

[A 15-year old boy with abdominal pain].

A 15-year-old boy came to the emergency department with abdominal pain in the left lower quadrant. The medical history included surgery for malrotation of bowel in two of his brothers. A CT-abdomen showed malrotation of the colon with a left-sided appendicitis and polysplenia.
