Presence of an Attachment Figure Is Associated With Greater Sensitivity to Physical Pain Following Mild Social Exclusion

Social exclusion has been shown to influence sensitivity to physical pain. Attachment theory suggests a primary response to rejection should be seeking out the company of a close other. Based on this prediction, we hypothesized that the presence of an attachment figure versus a stranger following rejection would permit acknowledgement of distress and thus stronger reports of physical pain. Healthy participants reported their pain sensitivity before receiving exclusion or inclusion feedback in an online chat. Participants were then randomly assigned to have access to their attachment figure or a stranger and had pain sensitivity measured again. As predicted, excluded participants who had access to their attachment figure evidenced heightened pain sensitivity (lower pain threshold and tolerance), whereas those who sat with a stranger evidenced some degree of a decrease in pain sensitivity (higher pain tolerance). These data may shed light on the impact social ties can have during painful situations.

Reversal of the Symptoms of Diabetic Neuropathy through Correction of Vitamin D Deficiency in a Type 1 Diabetic Patient

Vitamin D deficiency has been associated with both type 1 and type 2 diabetes as well as both the microvascular and macrovascular complications of diabetes. Vitamin D deficiency has been shown to be more common in diabetic patients who have symptoms of distal symmetrical polyneuropathy. In addition, vitamin D deficiency has been associated with a lower pain threshold which increases when vitamin D deficiency is corrected. Herein, I describe a type 1 diabetic patient with neuropathic symptoms so severe that he could not work and for which he needed narcotics for pain management and whose symptoms improved dramatically with correction of the vitamin D deficiency. To my knowledge, this is the first report of an improvement in severe symptoms of diabetic neuropathy with correction of vitamin D deficiency in a single patient.
