Treatment with botulinum toxin is widely viewed as safe, effective and largely devoid of serious side effects. There are two classes of Botox-related adverse events-transient and benign events, and potentially serious events. The aim of this study was to provide an overview of Botox-related side effects and advise potential management and preventive strategies. Benign side effects are well-localized, reversible and self-limited complications which develop within a few days of the injection, and they usually disappear without any treatment. The aesthetic and functional adverse effects are associated with different muscle responses to botulinum toxin or with misplacement of botulinum toxin. The serious events are sequelae due to the systemic spread of toxin leading to botulism.
Introduction One of the most important symptoms of Sjögren syndrome is xerostomia. The oral cavity deprived of saliva and its natural lubricative, protective and antibacterial properties is prone to a number of unfavourable consequences. Aim To present the most important lesions on the oral mucosa in primary and secondary Sjögren syndrome and in dry mouth syndrome. Material and methods The study group comprised 55 patients including 52 women and 3 men aged 20–72 years (average: 28.25 years). Results Basing on the accepted criteria, primary Sjögren syndrome was diagnosed in 22 (40%) patients, secondary Sjögren syndrome in 18 (32.7%) patients, and dry mouth syndrome in 15 (27.27%) patients. The physical examination and the examination of the mouth were performed and history was elicited from every patient. Conclusions The most common pathologies appearing on the oral mucosa in primary and secondary Sjögren syndrome are angular cheilitis, cheilitis, increased lip dryness as well as non-specific ulcerations, aphthae and aphthoid conditions.
Introduction: Oral lesions are divided into non-neoplastic lesions, potentially malignant lesions and neoplastic lesions. More clinical data are needed to determine their helpful clinical pattern. Aim: To present the epidemiological, clinical and histopathological characteristics of the oral lesions. Material and methods: The retrospective study group comprised records of 208 patients which were reviewed according to selected epidemiological and clinical features. All the biopsy specimens were classified into: reactive lesions, precancerous lesions/potentially malignant lesions, salivary gland pathologies, benign and malignant tumours. Results: The lower lip was the most common site involved followed by buccal and vestibular mucosa. The most frequent diagnoses were fibroma, mucocele and papilloma. The predominant pathomorphological forms were nodule and bulla. The most frequent salivary gland pathology was mucocele. Fibroma was the most frequent pathomorphological diagnosis, followed by mucocele and reactive lesions such as irritation fibroma (IF) and granuloma. Conclusions: In cases of oral mucosal lesions, we propose the following algorithm: the exclusion of all odontogenic and iatrogenic causes; the detection and elimination of harmful habits, parafunctions and irritants from the oral cavity especially from the vestibule of the oral cavity and from the lips; all surgical treatment should be performed only after the proper detection and elimination of causative factors to decrease the risk of recurrence; excisional biopsy or in more diffuse lesions incisional biopsy is recommended to confirm clinical diagnosis; and consideration of other factors that can modify the clinical pattern of oral lesions, such as oral hygiene, systemic diseases, and drugs.
IntroductionA prolonged feeling of shame leads to particularly negative consequences and it accompanies, as well as triggers, any kind of stigma.AimAs empirical works on shame due to stigmatizing diseases are scarce, the authors aimed to investigate the following: 1) which diseases are perceived as the most embarrassing, and 2) what level of shame is attributed to the embarrassing diseases by affected patients. Additionally, the authors assumed that the differentiation variable for the second aim would be the level of infectiousness (or non-infectiousness) of a given disease.Material and methodsA two-stage study was carried out in 2011–2013. Three groups of patients affected by various diseases were included into the actual study: 1) people suffering from non-infectious (42 psoriasis and 42 acne subjects) and 2) infectious (25 syphilis cases) diseases. The patients filled in an original questionnaire, designed especially for the purpose of the study.ResultsAs the most shameful acne patients consider syphilis, but patients with syphilis – AIDS. Patients with syphilis assigned to their disease the greatest shame (average 75%), and the lowest – acne patients (average 30%). Patients with psoriasis assessed on 52% shame experienced because of the disease.ConclusionsThe conducted study confirmed the accuracy of the empirical assumptions which may be applicable in prevention as well as therapy of negative consequences of shame.
Cholesteatoma represents progressive expansion of the keratinizing squamous epithelium in the middle ear with subsequent chronic inflammation in subepithelial connective tissues. The hypothesis was tested that receptor for advanced glycation endproduct (RAGE) and its ligand, high-mobility box 1 (HMGB1), are overexpressed in cholesteatoma, and the RAGE/HMGB1 axis might contribute to its pathogenesis. Cholesteatoma samples (n = 36) and 27 normal skin specimens were studied by immunohistochemistry (IHC) for HMGB1 and RAGE expression. Effects of HMGB1 signaling on proliferation, migration, cytokine production, and apoptosis of human immortalized keratinocytes (HaCaTs) and normal keratinocytes were studied by quantitative reverse transcription (qRT)-PCR, IHC, Western blots, and flow cytometry after cell co-incubation with HMGB1. While all studied tissues expressed HMGB1, its expression was higher in cholesteatoma than in normal skin (p < 0.0001). All cases of cholesteatoma also showed elevated RAGE expression levels, and only 7/27 (26 %) of normal skin specimens were weakly positive for RAGE. Proliferation and migration of HaCaT cells incubated with HMGB1 were up-regulated (p < 0.05). HMGB1 also prevented HaCaT cell apoptosis and induced activation of several molecular signaling pathways in keratinocytes. The data suggest that in cholesteatoma, HMGB1 released from stressed or necrotic epithelial cells and binding to RAGE overexpressed in keratinocytes initiates molecular signaling that culminates in pro-inflammatory cytokine release and chronic inflammation.Key messageHMGB1 signaling engages multiple activation pathways in RAGE-positive keratinocytes.HMGB1 protects RAGE-positive keratinocytes from drug-induced apoptosis.Keratinocyte proliferation is controlled via RAGE and HMGB1 molecular signaling.Molecular signaling of the HMGB1/RAGE axis contributes to cholesteatoma pathogenesis.Electronic supplementary materialThe online version of this article (doi:10.1007/s00109-014-1217-3) contains supplementary material, which is available to authorized users.
Our aim was to assess the use of the internet for patients considering rhinoplasty, to identify the influence of the medical information acquired, and to review favourable and adverse aspects of the acquired knowledge online. A prospective study was conducted on 106 patients listed for post-traumatic or aesthetic rhinoplasty. We surveyed 18 questions to evaluate demographic and sociological data, and the importance of the information acquired from the internet. Respondents searched online for description of operations, contact with other patients, and with the surgeon, and for preoperative and postoperative pictures. Patients who were considering aesthetic rhinoplasty were given medical information by a third party or from the internet, and those who were having post-traumatic corrections were usually referred by their general practitioner. We conclude that the internet is an important source of medical information about rhinoplasty for patients, but it does not contain enough data. It plays an essential part, particularly for those patients having the operation for aesthetic reasons, in contrast to those having post-traumatic correction. Reviewing and certifying the plastic surgical websites would validate certified services. Independent, direct contact with the doctor helps patients to obtain more accurate, personalized knowledge. In addition, surgeons should support patients by giving them a list of verified websites, which would contribute to increased doctor-patient communication.
