Screening for thyroid dysfunction and diabetes in patients with carpal tunnel syndrome.

BACKGROUND: Current literature demonstrates that patients with carpal tunnel syndrome (CTS) have a higher prevalence of hypothyroidism and diabetes. The British Society for Surgery of the Hand (BSSH) advises screening CTS patients for thyroid and glucose dysfunction before surgery. This study aimed to analyze the current departmental practice for patients listed for carpal tunnel decompression (CTD) with respect to preoperative assessment of diabetic and thyroid status. METHOD: A retrospective review of all patients who underwent surgery for CTS under one team over a 3 year period (2009-2011) in a UK teaching hospital was performed. Patients' medical records and pathology results were reviewed. RESULTS: A total of 103 procedures were performed in 100 patients. Preoperative thyroid function was checked in 63/100 patients with an abnormal result in 3/63 patients. Two of these patients were subsequently diagnosed with hypothyroidism. Similarly blood glucose was checked in 67/100 patients. This resulted in the new diagnosis of three patients with diabetes. CONCLUSION: The results are consistent with the view that CTS is associated with thyroid dysfunction and diabetes and screening helps in diagnosing new cases of these conditions in this select group. The cost of diagnosing new cases of hypothyroidism and diabetes can be considered as money well spent.

Life-threatening haemorrhage secondary to nicorandil-induced severe peri-anal ulceration.

Nicorandil-induced ulceration is rare but has been reported at multiple sites throughout the gastrointestinal tract. We report a life-threatening complication of such ulceration - catastrophic per-rectal haemorrhage requiring emergency surgery with no prior symptoms. Whilst nicorandil should be considered in cases of chronic peri-anal and peristomal ulceration which fail to respond to conventional treatments, this case highlights its importance in the setting of acute surgical presentations.
