Prospective assessment of function and cold-intolerance following revascularization for hypothenar hammer syndrome.

Ulnar artery revascularization in hypothenar hammer syndrome has repeatedly been shown to reduce ischaemic symptoms, however with varying graft patency percentages. This study prospectively assesses the effect of revascularization surgery with a vein graft using validated questionnaires in seven patients. The Disabilities of the Arm, Shoulder and Hand (DASH) and the Cold Intolerance Symptom Severity (CISS) questionnaires have been used to compare the preoperative and postoperative functionality and cold intolerance.

Postoncological lacrimal duct reconstruction: A practical classification system for reconstructive planning and short-term results of a case series.

Background: Surgical resection of skin tumors in the medial canthal area may damage the lacrimal duct and can result in chronic epiphora. Postoncologic reconstruction of the lacrimal duct has not been studied extensively. The current study discusses the anatomical and functional features of the lacrimal duct.

Evaluation of Cancer-Associated DNA Copy Number Events in Colorectal (Advanced) Adenomas.

About 5% of colorectal adenomas are estimated to progress to colorectal cancer. However, it is important to identify which adenomas actually carry a high risk of progression, because these serve as intermediate endpoints, for example, in screening programs. In clinical practice, adenomas with a size of ≥10 mm, villous component and/or high-grade dysplasia, called advanced adenomas, are considered high risk, although solid evidence for this classification is lacking.

[A long-standing swelling on the shoulder].

We present a 49-year-old woman with a cutaneous horn on the right shoulder since 20 years. Cutaneous horn is a clinical diagnosis referring to a benign or malignant lesion of the skin with a conical projection of cornified material. It is most common on sun-exposed skin.

Efficacy versus Complications in Arterial Thrombolysis.

Background: Acute peripheral arterial occlusions threaten life and limb. Thrombolysis is an established, minimally invasive alternative treatment for surgical thromboembolectomy. Yet, there is no consensus regarding an optimal thrombolysis protocol, and current knowledge is largely based on studies from the 1990s.

Activation of extracellular signal-related kinase in abdominal aortic aneurysm.

Background: Extracellular matrix degeneration, caused by matrix metalloproteinase-2, facilitates smooth muscle cell migration leading to medial layer decline and, ultimately, abdominal aortic aneurysm. It remains unclear what exactly causes aneurysms to rupture, which leads to death in most patients. The extracellular signal-related kinase may be linked to the latter process.
