Breast cancer incidence suggests a lifestyle cause. A lifestyle factor used near the breast is the application of antiperspirants/deodorants accompanied by axillary shaving. A previous study did not support a link with breast cancer. If these habits have a role in breast cancer development, women using antiperspirants/deodorants and shaving their underarms frequently would be expected to have an earlier age of diagnosis than those doing so less often. An earlier age of diagnosis would also be expected in those starting to use deodorants and shaving at an earlier age. This is the first study to investigate the intensity of underarm exposure in a cohort of breast cancer survivors. Four hundred and thirty-seven females diagnosed with breast cancer were surveyed. Once grouped by their frequency of underarm hygiene habits, the mean age of diagnosis was the primary end point. Secondary end points included the overall frequency of these habits, and potential usage group confounding variables were evaluated. All statistical tests were two-sided. Frequency and earlier onset of antiperspirant/deodorant usage with underarm shaving were associated with an earlier age of breast cancer diagnosis. Combined habits are likely for this earlier age of diagnosis. In conclusion, underarm shaving with antiperspirant/deodorant use may play a role in breast cancer. It is not clear which of these components are involved. Reviewed literature insinuates absorption of aluminium salts facilitated by dermal barrier disruption. Case-controlled investigations are needed before alternative underarm hygiene habits are suggested.
Stevens-Johnson syndrome (SJS) is a severe cutaneous eruption that can be a life-threatening emergency. Previously, we have reported our favorable experience in treating 54 patients with SJS with systemic corticosteroids. We continued our prospective analysis of consecutive patients with SJS treated with corticosteroids. Possible etiologic factors and clinical outcomes of the patients are described. All 13 patients improved with initiation of systemic corticosteroid therapy. There was no mortality or permanent sequelae attributable to SJS. Drugs were the offending agents in all 13 cases. There was one death unrelated to SJS. In conclusion, prompt treatment with systemic corticosteroids reduces morbidity and improves outcome of SJS patients. This analysis extends our series to 67 consecutive patients with SJS who were treated with corticosteroids and had a favorable outcome.
Rhinitis is characterized by nasal congestion, rhinorrhea, sneezing, and/or posterior nasal drainage. It affects a significant portion of the population and presents a large burden economically and on quality of life. Rhinitis is broadly characterized as allergic and nonallergic, of which nonallergic rhinitis may be divided into inflammatory and noninflammatory etiologies. The inflammatory causes include nonallergic rhinitis with eosinophilia, postinfectious, and rhinitis associated with nasal polyps. The noninflammatory causes include idiopathic nonallergic (vasomotor) rhinitis, medication-induced rhinitis, hormone related (e.g., pregnancy), and systemic disease related. Allergic rhinitis is classified as intermittent or persistent and mild versus moderate-severe. The nasal mucosa is extremely vascular; parasympathetic stimulation promotes an increase in nasal cavity resistance and nasal gland secretion, whereas sympathetic stimulation leads to vasoconstriction. The diagnosis of rhinitis begins with a directed history, particularly noting pattern, chronicity, and triggers of symptoms. Examination of the nasal cavity with attention to appearance of the septum and inferior turbinates is recommended. Skin testing for aeroallergens is helpful in demonstrating the presence or absence of immunoglobulin E antibodies and to differentiate nonallergic from allergic rhinitis. Treatment includes patient education, irritant or allergen avoidance, and pharmacotherapy. Medications used for the treatment of rhinitis include intranasal corticosteroids, oral and intranasal antihistamines, intranasal anticholinergic agents, oral decongestants, and leukotriene receptor antagonists. When used in combination, an intranasal antihistamine spray and nasal steroid provide greater symptomatic relief than monotherapy. Allergen immunotherapy is the only disease-modifying intervention available for allergic rhinitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
