A 49-year-old man presented to hospital with severe orthostatic hypotension, gingival dysplasia and a purpuric rash involving his extremities. The orthostatic hypotension failed to respond to fluids and, on the basis of physical examination and dietary history, the patient was given a preliminary diagnosis of scurvy (ascorbic acid deficiency). Serum ascorbic acid levels were undetectable and the orthostasis was resolved within 24 h of ascorbic acid replacement. The pathogenesis of orthostatic hypotension in the setting of scurvy appears to involve impaired catecholamine synthesis and attenuated vasomotor response to α-adrenergic stimulation. We believe that this case describes a rare presentation of scurvy and highlights a previously under-reported connection between scurvy and vasomotor instability.

BACKGROUND: Fecal microbiota transplantation (FMT) is a safe and effective, yet infrequently used therapy for recurrent Clostridium difficile infection (CDI). OBJECTIVE: To characterize barriers to FMT adoption by surveying physicians about their experiences and attitudes toward the use of FMT. METHODS: An electronic survey was distributed to physicians to assess their experience with CDI and attitudes toward FMT. RESULTS: A total of 139 surveys were sent and 135 were completed, yielding a response rate of 97%. Twenty-five (20%) physicians had treated a patient with FMT, 10 (8%) offered to treat with FMT, nine (7%) referred a patient to receive FMT, and 83 (65%) had neither offered nor referred a patient for FMT. Physicians who had experience with FMT (performed, offered or referred) were more likely to be male, an infectious diseases specialist, >40 years of age, fellowship trained and practicing in an urban setting. The most common reasons for not offering or referring a patient for FMT were: not having 'the right clinical situation' (33%); the belief that patients would find it too unappealing (24%); and institutional or logistical barriers (23%). Only 8% of physicians predicted that the majority of patients would opt for FMT if given the option. Physicians predicted that patients would find all aspects of the FMT process more unappealing than they would as providers. CONCLUSIONS: Physicians have limited experience with FMT despite having treated patients with multiple recurrent CDIs. There is a clear discordance between physician beliefs about FMT and patient willingness to accept FMT as a treatment for recurrent CDI.
