The effect of perioperative beta-blockade on the pulmonary function of patients undergoing major arterial surgery.
Concern about the potential detrimental side-effects of beta-blockade on pulmonary function often dissuades against their perioperative use in patients undergoing major arterial surgery (especially in those with chronic obstructive pulmonary disease (COPD)). In this study we aimed to establish prospectively the clinical relevance of these concerns. ⋯ Previously held concerns about worsening pulmonary function through the short-term use of beta-blockers should not dissuade their perioperative usage in patients with peripheral vascular disease. Furthermore, the accuracy of pulmonary function tests in preoperative assessment and risk stratification also appears unaffected by this therapy.

Occult renal impairment is common in patients with peripheral vascular disease and normal serum creatinine.
The incidence of peripheral vascular disease (PVD) and angiography/angioplasty is rising annually. The UK Small Aneurysm Trial and other trials have shown renal function is a predictor of increased mortality and failed infrainguinal bypass despite patent vessels. Renal function is classically assessed by serum creatinine (SCr). However, SCr can be normal despite significant renal impairment. A more sensitive test is creatinine clearance (CrCl) as determined by 24-hour urine collection in combination with SCr. We studied the incidence of renal impairment, as defined by CrCl, in PVD patients with normal SCr. ⋯ Most PVD patients with normal serum creatinine have occult, significantly impaired renal function as defined by creatinine clearance. Vascular surgeons should include creatinine clearance in pre-operative assessment of renal function especially in patients over 75 years old, with a history of coronary heart disease or a serum creatinine over 85 micromol/l. The method of determining creatinine clearance could be the Cockcroft-Gault calculation or ideally 24-hour urinary creatinine clearance measurement. This would allow appropriate early referral to a nephrologist for further investigation and management. It is worth noting that statin use seems to be associated with a protective effect on renal function.

Case ReportsHypothenar Hammer Syndrome: rare or underdiagnosed?
Hypothenar hammer Syndrome (HHS) is a condition characterised by digital ischaemia as a result of repetitive trauma to the hypothenar eminence of the hand. It occurs in people who repeatedly use the palm of the hand as a hammer to push, grind or twist objects. ⋯ In this report we present a case of HHS and discuss the causes and pathogenesis of this syndrome. We review the incidence, clinical characteristics, differential diagnosis, investigation and treatment.
