'Intranasal toothache': case report.

OBJECTIVE: This paper describes a patient with recurrent unilateral nasal discomfort and pain due to an intranasal tooth. A short overview of the literature is provided in relation to the aetiology, symptomatology, diagnosis and treatment of intranasal teeth. CASE REPORT: A 26-year-old man was referred with a history of recurrent left-sided nasal obstruction, facial pain and discomfort, and chronic purulent rhinorrhoea. Computed tomography revealed a nasal tooth, which was likely to have been the cause of these symptoms. After transnasal surgical extraction under endoscopic guidance, the patient was relieved of his complaints (at the one-year follow up). CONCLUSION: An ectopic tooth in the nasal cavity is a rare phenomenon, and in most cases the cause of an intranasal tooth remains unclear. The treatment of an intranasal tooth entails surgical extraction even though such teeth may remain asymptomatic; several cases have illustrated the potential significant morbidity associated with their occurrence.

A non-traumatic, blue-purple auricle: case report.

OBJECTIVE: We report a typical case of earlobe lymphocytoma. METHOD: A case report and literature review are presented. RESULTS: A 10-year-old girl presented with a blue-coloured earlobe. A diagnosis of Lyme disease was confirmed by serological tests. Lyme borreliosis is the most common tick-borne disease in the northern hemisphere. It is caused by the spirochete Borrelia burgdorferi sensu lato. The patient was successfully treated with antibiotics. CONCLUSION: The diagnostic process and ENT symptomatology of Lyme disease and borrelial lymphocytoma are summarised and discussed.

Intralesional triamcinolone acetonide injection in hypertrophic skin surrounding the percutaneous titanium implant of a bone-anchored hearing aid.

OBJECTIVE: We present a patient with persistent hypertrophic skin surrounding the percutaneous implant of a bone-anchored hearing aid system, successfully treated with intralesional applied corticosteroids. METHOD: Case report and review of the world literature concerning bone-anchored hearing aid implantation and intralesional applied corticosteroids for the treatment of hypertrophic scars and keloids. RESULTS: Eight weeks after revision surgery to reduce surplus skin and subcutaneous scar tissue overgrowing the abutment, skin and subcutaneous scar tissue overgrowth reoccurred. As an alternative to yet another surgical procedure, the hypertrophic skin was treated with intralesional injections of triamcinolone acetonide. Three weeks after the treatment, a satisfying result was seen, and no subsequent relapse was observed. CONCLUSION: To our knowledge, this is the first, photographically well documented case report of a patient with persistent hypertrophic skin surrounding a percutaneous bone-anchored hearing aid implant, successfully treated with intralesional applied corticosteroids.

Idiopathic rhinitis, the ongoing quest.

The term rhinitis in daily practice is used for nasal dysfunction causing symptoms-like nasal itching, sneezing, rhinorrhea and or nasal blockage. Chronic rhinitis can roughly be classified into allergic, infectious or nonallergic/noninfectious. When allergy, mechanical obstruction and infections have been excluded as the cause of rhinitis, a number of poorly defined nasal conditions of partly unknown aetiology and pathophysiology remain. The differential diagnosis of nonallergic noninfectious rhinitis is extensive. Although the percentage of patients with nonallergic noninfectious rhinitis with a known cause has increased the last decades, still about 50% of the patients with nonallergic noninfectious rhinitis has to be classified as suffering from idiopathic rhinitis (IR), or rather e causa ignota. Specific immunological, clinical and sometimes radiological and functional tests are required to distinguish known causes. Research to the underlying pathophysiology of IR has moved from autonomic neural dysbalans to inflammatory disorders (local allergy), the nonadrenergic noncholinergic (NANC) sensory peptidergic neural system and central neural hyperaesthesia, still without solid ground or proof. This review summarizes the currently known causes for nonallergic noninfectious rhinitis and possible treatments. Also possible pathophysiological mechanisms of IR are discussed.

Intranasal capsaicin reduces nasal hyperreactivity in idiopathic rhinitis: a double-blind randomized application regimen study.

BACKGROUND: In a recent study, we showed that intranasal capsaicin spray gives a significant and long-term reduction of symptoms in nonallergic noninfectious perennial rhinitis patients. However, in daily practice, the studied application regimen proved to be impractical because of the large number of visits required in a short period of time. In the present study, we conducted a double-blind double-dummy parallel groups trial to determine whether a more practical capsaicin application schedule is equally effective. METHODS: Thirty patients were randomized into two different treatment regimens: one group received capsaicin five times on the first day at 1-h intervals. This was followed by a placebo dummy once every second or third day for a total of five treatments 2 weeks after the capsaicin application (group A). The other group (B) received the placebo dummy five times on the first day followed by capsaicin once every second or third day for a total of five treatments 2 weeks after the placebo application. RESULTS: The visual analogue scale scores for overall nasal symptoms, rhinorrhea and nasal blockage showed significant decrease after the start of treatment in both groups, with a significantly steeper decrease in group A. A significant reduction in cold dry air dose responsiveness was also found up to 9 months after therapy in both groups, reflecting a decrease in nasal hyperreactivity. No significant changes in safety data (smell, blood pressure, heart rate) were found. CONCLUSIONS: We conclude that intranasal capsaicin seems safe to use and that five treatments of capsaicin on a single day is at least as effective as five treatments of capsaicin in 2 weeks.

Inflammatory cells seem not to be involved in idiopathic rhinitis.

Mucosal inflammatory cellular infiltrates are correlated with nasal complaints in symptomatic allergic rhinitis. Some authors suggest inflammation of a neurogenic or immunogenic nature as an underlying disorder for idiopathic rhinitis (IR). We looked at the possible involvement of inflammatory cells in the pathogenesis of IR. Nasal biopsies were taken from sixty-five IR patients with significant nasal complaints and from twenty healthy controls with no nasal complaints. Inflammatory cells were quantified using monoclonal antibodies directed against lymphocytes, antigen-presenting cells, eosinophils, macrophages, monocytes, mast cells and other IgE-positive cells. No significant differences were found, for any cell, between IR patients and controls. We conclude that inflammatory cells do not seem to play an important role in this meticulously characterised group of IR patients.

The long-term effects of capsaicin aqueous spray on the nasal mucosa.

BACKGROUND: Capsaicin has been shown previously to reduce nasal complaints in patients with a non-allergic non-infectious perennial rhinitis. Proposed pathophysiological mechanisms for non-allergic non-infectious perennial rhinitis include a chronic inflammatory disorder of an antigenic or neurogenic nature as well as the possibility of a functional neuronal disorder. We hypothesized that the beneficial effect of capsaicin might be the result of a down-regulation of inflammation (by a reduction of inflammatory cells) or through modulation of neural tissue density. METHODS: Patients were treated with either a placebo or capsaicin spray solution delivering 0.15 mg of capsaicin per nostril once every second or third day for a total of seven treatments. Both sides were treated each visit. Biopsies were taken before and 2 weeks, 3 months and 9 months after the treatment period. Immunohistochemical staining of the biopsy specimen was performed to ascertain the effect of treatment on immunocompetent cell densities (quantitative) and neural tissue densities (semi-quantitative) in the nasal mucosa. RESULTS: Nasal complaints were significantly reduced in the capsaicin-treated group. The number of CD1+, CD25+, CD3+, CD68+, BMK13+, IgE+, tryptase+, and chymase+ cells did not significantly differ between capsaicin and placebo group. No significant differences between both groups were found in pan-neurogenic staining of nasal mucosa using neurofilament and synaptophysine. CONCLUSION: Capsaicin aqueous nasal spray has previously been shown to reduce nasal complaints without affecting cellular homeostasis or overall neurogenic staining up to 9 months after treatment. Immunocompetent cells are not involved in non-allergic non-infectious perennial rhinitis.

Intranasal capsaicin is efficacious in non-allergic, non-infectious perennial rhinitis. A placebo-controlled study.

BACKGROUND: Several authors described capsaicin, the pungent substance in red pepper, as an efficacious therapy for non-allergic non-infectious perennial rhinitis (NANIPER). Repeated capsaicin application induces peptide depletion and specific degeneration of the unmyelinated sensory C-fibres in the nasal mucosa. METHODS: We performed a placebo-controlled (NaCl 0.9%) study with 25 NANIPER patients. Daily record charts and visual analogue scales (VAS) were used for clinical evaluation. Nasal lavages were obtained before, during, and after treatment. RESULTS: There was a significant and long-term reduction in the VAS scores in the capsaicin group. No significant difference was found between the placebo and capsaicin treated groups for the mean group concentrations of leukotriene (LT) C4/D4/E4, prostaglandin D2 (PGD2), and tryptase. The levels of mast cell mediators, tryptase and PGD2, and leukotrienes, mediators derived from a variety of inflammatory cells, were low at baseline and comparable with levels observed in nasal lavages obtained from normals. CONCLUSION: As involvement of inflammation could not be demonstrated, it is not surprising that capsaicin has no effect on inflammatory mediators. This suggests that inflammatory cells do not play a major part in the pathogenesis of NANIPER.
