Self-induced Nasal Ulceration

International Journal of Psychophysiology, 2003

The paper describes methods which allow intranasal irritation using short-and long-lasting painful stimuli in humans. Short-lasting pain is induced by gaseous CO , while long-lasting pain is induced by a stream of dry air. Both models have been explored regarding their major determinants, e.g. stimulus duration, stimulus intensity, or repeated stimulation. Short-lasting, non-inflammatory pain stimuli seem to provide specific indicators of A -fiber delta function, while responses to long-lasting, inflammatory pain appear to be indicative of C-fiber function. Responses to both types of painful stimuli are modulated by analgesic drugs. As these well-investigated models allow the detailed and precise analysis of modulatory effects on intranasal nociception, they appear to be suited for the investigation of subtle changes of intranasal irritation, e.g. induced by environmental agents. ᮊ

BACKGROUND. Trigeminal trophic syndrome is a unilateral, frequently crescent-shaped neurotrophic ulceration of the face occurring after injury to the trigeminal nerve. The appearance of the ulcers resembles other disease entities such as granulomatous disease, neoplasm, vasculitis, infection, and factitial dermatitis. OBJECTIVES. The objectives of this study are to increase awareness of this disorder and to emphasize the importance of eliciting a thorough neurologic history when evaluating facial ulcerations. METHODS. Four cases are reported and, using MEDLINE, the English and non-English literature from 1982 to 2002 is reviewed. RESULTS. Including this report, there have been 60 cases of trigeminal trophic syndrome reported from 1982 to 2002. The

Introduction: Non-healing ulcers can be caused by a number of conditions, including vascular disease, diabetes, malignancy and some infections. Drug-related ulcers are rare, and a high index of clinical suspicion is required for diagnosis, in parallel with exclusion of more sinister underlying causes. Case report: We present a patient with a complex medical background, who had a 10-week history of a non-healing ulcer on his nasal bridge. Inflammatory, autoimmune and malignant causes for the ulcer were excluded by histopathology. Conclusion: Nicorandil was deemed to be the most likely cause for the patient's ulcer. Nicorandil is an anti-anginal medication known to cause oral ulceration and skin lesions in the perianal and peristomal regions and around surgical wounds. However, there are no previously reported cases of facial ulcers. The ulcer required surgical debridement and healed completely within six months, following discontinuation of nicorandil. This case highlights the importance of having a high index of clinical suspicion regarding non-healing ulcers, and of considering drugs as an aetiological factor, especially in patients with a complex medical background who are taking numerous medications.

Trigeminal trophic syndrome is an uncommon clinical entity in which cutaneous trophic ulceration develops with continuous manipulation of trigeminal dermatomes. Patients spontaneously refer picking, rubbing and/or scratching at the affected areas because of hypo-anaesthesia, paraesthesia and/or pain following damage of the sensory trigeminal fibres or nuclei. We herein describe a patient who developed the syndrome as a sequela of brain stem infarction. Diagnosis by scrape cytology in ruling-out basal cell carcinoma and other ulcerative skin diseases is discussed and the importance of neurological examination in disclosing hemi-anaesthesia of trigeminal dermatome(s) is emphasized.

A case about a HIV woman with nasal ulcers is described in this paper. In every inmunodepressed patient who has mucosal or cutaneous ulcers, infection by leishmanial parasites needs to be ruled out, especially when ulcers have not regression with usual treatments. The Leishmanial nasal disease usually shows swelling and mucosal ulcers, that may progress to necrosis. Delaying in appropriate therapy might cause irreversible damage.

This study describes the management of 216 patients with post-traumatic iatrogenic lingual nerve injuries (LNIs; n=93) and inferior alveolar nerve injuries (IANI; n=123). At initial consultation, 6% IANI and 2% LNI patients had undergone significant resolution requiring no further reviews. Reassurance and counselling was adequate management for 51% IANI and 55% LNI patients. Systemic or topical medication was offered as pain relief to 5% of patients. Additional cognitive behaviour therapy (CBT) was offered to 8% of patients. Topical 5% lidocaine patches reduced pain and allodynia in 7% of IANI patients, most often used without any other form of management. A small percentage of IANI patients (4%) received a combination of therapies involving CBT, surgery, medication and 5% lidocaine patches. Exploratory surgery improved symptoms and reduced neuropathic area in 18 LNI and 15 IANI patients resulting in improved quality of life. In conclusion, the authors suggest a more diverse and per...

Trigeminal neuralgia is a quite common classic neuralgia and commonest cause of facial pain after 50. It is known to have the worst possible pain in the world; previously it was termed as suicidal pain. The incidence of Trigeminal Neuralgia (TN) is 4.3 per 100,000 persons per year, with a slightly higher incidence for women (5.9/100,000) compared with men (3.4/100,000). It is almost exclusively unilateral neuropathic pain. The pain is located in the distribution of trigeminal nerve. The burst of pain can occur spontaneously or from a stimulus in the specific area of the face known as trigger zone. Sometimes it is difficult to identify the trigger zone. Patient usually avoid touching, brushing or chewing to avoid stimulation of trigger zone. Pain may occur daily for week, months and then cease, sometimes for months to years this is called remission period. Evidence suggests that pain occurs because of pressure on the trigeminal nerve root at the entry zone into the pontine region of ...

Trigeminal neuralgia (TN) is a debilitating disorder that presents with a sudden onset of severe, unilateral, paroxysmal, and lancinating pain in one or more of the distributions of the trigeminal nerve. Trigeminal neuralgia affects the trigeminal nerve, fifth most developed and extensive cranial nerve, with a broad distribution territory. Its name - “trigeminal” - is derived from the fact that each nerve, one on each side of the pons, has three major branches: the ophthalmic nerve (V1), the maxillary nerve (V2) and the mandibular nerve (V3). The ophthalmic and maxillary nerves are purely sensory. The mandibular nerve has both sensory and motor functions.[1] It is a mixed nerve conducting sensitive and motor somatic fibers to the face, and is ideally responsible for all its sensitive innervation (touch, pain, temperature and propioception) together with the motor innervation of the mastication apparatus. Though it has been known by various names in the literature such as tic douloureux, trifacial neuralgia, fothergill’s disease (named after john fothergill), the currently accepted terminology is trigeminal neuralgia.[2]

Numbness and ulceration of the face, particularly erosion of ala of the nose, sometimes occur after sensory denervation in the territory of the divisions of the trigeminal nerve. The incidence is uncertain and usually follows surgical treatments for trigeminal neuralgia. Such condition is known as trigeminal trophic syndrome (TTS), although some authors believe it to be a special form of dermatitis artefacta. Trigeminal trophic syndrome most commonly affects adults, after iatrogenic, vascular, viral, or neoplastic damage to the trigeminal nerve. We present a rare case of TTS in a 32-year-old woman who was referred to us with progressive numbness in the right upper and lower lip region.
