Urtication refers to the deliberate stinging of the skin with nettles. Throughout history urtication has been used for a range of different purposes. This case describes an interesting clinical encounter in which a patient with recurring low back pain reports using urtication to help with pain control. Some recent research into this previously more widespread pain-relieving strategy is also discussed.

A healthy 29-year-old woman received epidural block for severe lumbago in an outpatient clinic. Fifteen minutes after injection of mepivacaine 0.5% with dexamethasone into the epidural space, the patient complained of itching of eyelids followed by generalized pruritus. Hypotension, erythema and generalized urticaria were observed. Initial treatment was with 100% oxygen through face mask, and additional intravenous fluids, followed by administration of adrenaline, chlorpheniramine and dopamine. Cardiac ultrasound examination showed mildly impaired movement of inferior to septal wall. Her plasma histamine level was transiently elevated during the anaphylactic event; however the serum tryptase level was not. Biological assays for confirming the causative agent and cutaneous test were all negative, but clinical symptoms positivity showed nonimmunological anaphylactic reaction to mepivacaine or dexamethasone. This case report confirms the need for systematic allergological investigation in a case of immediate hypersensitivity reaction occurring during nerve block in patients who had even received similar nerve blocks repeatedly. Pain clinician should be aware of the possibility of anaphylactic reactions involving any drug or substance used for an outpatient.

A 29-year-old woman had an episode of urticaria at the age of 17 while exercising after eating fried cuttlefish. For years thereafter, she experienced several episodes of urticaria after eating seafood. At the age of 29, she ate grilled seafood, including cuttlefish for supper after taking loxoprofen for lumbago. One hour later, she developed generalized urticaria accompanied by nausea, abdominal pain, swelling of the lips, and dyspnea while walking; she was taken to a hospital. She was then referred to us for further examination of the etiology of her anaphylactic reactions. The level of specific IgE measured using Immuno CAP was negative for all kinds of foods, including cuttlefish. However, a skin prick test was positive for raw and cooked cuttlefish. Provocation tests were performed on admission by combining the intake of cuttlefish and aspirin under the suspicion of cuttlefish allergy enhanced by nonsteroidal anti-inflammatory drugs and exercise. As a result, she developed no symptoms except for slight itching of the oral mucosa after eating 20 g or 100 g of cuttlefish with or without concomitant administration of 0.5 g of aspirin. Finally, generalized urticaria appeared after challenge with cuttlefish and 1.5 g of aspirin. She was diagnosed with food-dependent exercise-induced anaphylaxis (FDEIA) caused by cuttlefish. She has not developed urticaria since she started to avoid eating cuttlefish. Our results indicated that in provocation tests for the diagnosis of FDEIA, allergic reactions could not only be induced by food intake but could also be enhanced by aspirin in a dose-dependent manner.

An 83-year-old woman was referred to our emergency department with acute urticaria and sudden shortness of breath approximately 30 min after taking rectal diclofenac potassium for lumbago. After treatment with adrenaline and corticosteroids, the patient became hemodynamically stable and left the hospital on the next day. She attended our hospital 1 week after the onset of anaphylaxis because of repeated postprandial epigastric pain. No abnormal lesions were found in endoscopy. Radiographic selective catheter angiography revealed chronic mesenteric ischemia caused by atherosclerosis and abundant collateral arteries between the celiac trunk, the superior mesenteric artery and the inferior mesenteric artery. Patients with chronic mesenteric ischemia usually present with a clinical syndrome characterized by painful abdominal cramps and colic occurring typically during the postprandial phase. Fear of eating resulted in malnutrition. She was prescribed proton pump inhibitor, digestants, anticholinergic agents, serine protease inhibitors, prokinetics, antiplatelet agents and transdermal nitroglycerin intermittently, but these had no beneficial effects. It was most probable that this patient with chronic atherosclerotic mesenteric ischemia was suffering from functional abdominal pain syndrome induced by anaphylaxis. Since psychiatric disorders were associated with alterations in the processing of visceral sensation, we facilitated the patient's understanding of functional abdominal pain syndrome with the psychologist. Postprandial abdominal pain gradually faded after administration of these drugs and the patient left the hospital. Developing a satisfactory patient-physician relationship was considered more effective for the management of persistent abdominal pain caused by complicated mechanisms.
