Quality of life in patients with early-stage extra-nodal NK/T cell lymphoma of nasal type after definitive radiation therapy / 中华放射肿瘤学杂志

Objective:To investigate the quality of life in patients with early-stage extra-nodal NK/T cell lymphoma of nasal type (ENKTL) arising from the upper aerodigestive tract, who had remained progression-free survival (PFS) for over 3 months after definitive intensity-modulated radiation therapy (IMRT), and to analyze the factors related to main adverse symptoms.Methods:276 patients who received IMRT from March, 2012 to June, 2021 were included. There were 201 males and 75 females with a median age of 41.5 years (range: 13-81 years) upon diagnosis. Consistent target delineation schemes and similar dose gradients were adopted for IMRT, with a median prescribed dose of 54.6 Gy/26F. Cross-sectional investigation was performed with a modified EORTC QLQ-H&N35 questionnaire, the incidence and severity of adverse symptoms, severity of disease and their influencing factors at each time-point during their survival were statistically analyzed.Results:The median age of patients at the investigation was 46.2 years, and the median PFS after IMRT was 47.2 months (range: 3.1-115.7 months). The most common adverse symptoms included nasal symptoms (incidence rate 63.8%), dry mouth (50%), tooth diseases (47.1%), smell and taste alteration, and sexual apathy, etc. Most symptoms were mild (the average standardized score was 5.50, the full score of 100 indicating the most severe), and could be relieved remarkably over survival time, but some symptoms, such as tooth diseases and sexual apathy, were more obvious and recurred for several years. Age and anti-PD-1 immune therapy influenced the symptom scores, and tooth diseases were closely correlated with dry mouth. Conclusion:The quality of life in patients with early-stage ENKTL after definitive IMRT is high, and the most significant symptoms include nasal symptoms, tooth diseases, and sexual apathy, etc. , which need to be mitigated with more studies.

Research progress on oral characterization of Corona Virus Disease 2019 / 口腔疾病防治

@#Corona Virus Disease 2019 (Corona Virus Disease 2019,COVID-19) has become a public health emergency that has attracted global attention because of its large-scale outbreak resulting in numerous human infections and deaths. COVID-19 is a highly contagious respiratory disease caused by novel coronavirus 2019-nCoV. Due to a large number of infections and fast transmission speed, it's significant to diagnose the infected people quickly and detect the asymptomatic infected people as soon as possible. At present, the preliminary screening is judged by the clinical manifestations of the patients, mainly involving the respiratory system, but recent studies have found that the patients infected with COVID-19 have unique oral manifestations, such as taste disturbance, xerostomia, halitosis, inflammation of salivary glands, necrotizing periodontal disease and some of them are earlier than typical symptoms such as dry cough, fever, etc. Paying attention to the oral manifestations of patients can further improve the COVID-19 screening procedure. At present, symptomatic treatment is mainly used for these oral symptoms.

Prevalence of xerostomia and its association with systemic diseases and medications in the elderly: a cross-sectional study

ABSTRACT BACKGROUND: Dry mouth syndrome or xerostomia is defined as decreased salivary flow or hypofunction of salivary glands. Its origins are multicausal and might be the result of a change in the salivary glands or a systemic imbalance. OBJECTIVE: To ascertain the prevalence of self-reported xerostomia and to identify associated factors. DESIGN AND SETTING: Cross-sectional study on the entire population of 293 elderly people over 60 years of age living in a Brazilian municipality. METHODS: Data were gathered from a questionnaire that asked about demographic data, chronic diseases and use of continuous medications, and which used the Xerostomia Inventory (XI) to evaluate dry mouth sensation. Our analysis consisted of multivariate regression and estimation of odds ratios (OR) and their respective 95% confidence intervals (CI) in binary logistic regression models. RESULTS: The prevalence of self-reported xerostomia was 19.1%. Elderly people with diabetes had higher odds of having self-reported xerostomia (OR: 3.59; 95% CI: 1.48-8.68; P < 0.001) as did those who had chronic diseases and used continuous medication (OR: 2.3; 95% CI: 1.19-4.67; P = 0.009). Elderly people who used continuous medication for the gastrointestinal tract were more likely to have xerostomia (OR: 2.14; 95% CI: 1.03-1.44; P = 0.030). CONCLUSIONS: Elderly people with diabetes and chronic diseases who were using continuous medication were more likely to have dry mouth. Use of continuous medications for the gastrointestinal tract led to a greater chance of having self-reported xerostomia.

Oral manifestation in pre-renal transplant patients in Tertiary Care Hospital in Punjab

The incidence of renal failure is known to be increasing globally. Kidney transplant are considered the most efficient renal replacement therapy for a significant number of patients with end- stage renal disease. Renal failure can give rise to a large spectrum of oral manifestations, affecting overall health of patients with renal disease. End-stage renal disease (ESRD) patients have a plethora of oral findings. The aim of this study was to study oral symptoms and lesions in pre-renal transplant patients. This prospective study was conducted over a 6-month period. A total of 80 individuals (40 pre renal transplant patients and 40 controls) were recruited. Each patient was interviewed individually using questionnaire about oral symptoms. Each patient was examined for oral lesions and documented. For Caries DMFT and for Gingivitis CPITN index was used. In both study and control group majority were males and majority were in age group 21-30 years. In study group knowledge of importance of oral hygiene was more. The most common symptoms were dry mouth (20%), altered taste (52.5%) and bleeding gums (42.5%). Study group showed significantly more oral changes than those in the control group. DMFT index was positive in 60% of study and 80% control group. CPITN index was equally positive (92.5%) in both study and control group. Mucosal pallor, suburral tongue, leukoplakia and hyperplastic gingivitis was seen in 27.5%, 10%, 10% and 2.5% respectively in the study group. Prevalence of oral lesions is significantly higher in renal patients. The potential source of active infective lesions in medically compromised patients with ESRD must be treated before transplant.

Xylitol stimulates saliva secretion via muscarinic receptor signaling pathway

Xylitol is well-known to have an anti-caries effect by inhibiting the replication of cariogenic bacteria. In addition, xylitol enhances saliva secretion. However, the precise molecular mechanism of xylitol on saliva secretion is yet to be elucidated. Thus, in this study, we aimed to investigate the stimulatory effect of xylitol on saliva secretion and to further evaluate the involvement of xylitol in muscarinic type 3 receptor (M3R) signaling. For determining these effects, we measured the saliva flow rate following xylitol treatment in healthy individuals and patients with dry mouth. We further tested the effects of xylitol on M3R signaling in human salivary gland (HSG) cells using real-time quantitative reverse-transcriptase polymerase chain reaction, immunoblotting, and immunostaining. Xylitol candy significantly increased the salivary flow rate and intracellular calcium release in HSG cells via the M3R signaling pathway. In addition, the expressions of M3R and aquaporin 5 were induced by xylitol treatment. Lastly, we investigated the distribution of M3R and aquaporin 5 in HSG cells. Xylitol was found to activate M3R, thereby inducing increases in Ca²⁺ concentration. Stimulation of the muscarinic receptor induced by xylitol activated the internalization of M3R and subsequent trafficking of aquaporin 5. Taken together, these findings suggest a molecular mechanism for secretory effects of xylitol on salivary epithelial cells.

Xerostomía en pacientes con fibromialgia: Estudio epidemiológico / Xerostomia in fibromyalgia patients: Epidemiologic study

Introducción: Dentro de los fenómenos clínicos estudiados asociados a la Fibromialgia (FM) se ha descrito el Síndrome Sicca, cuyo término engloba xeroftalmia, xerostomía, xerodermia y xerovagina. El objetivo de este estudio fue estimar la frecuencia de xerostomía en pacientes con diagnóstico de fibromialgia y describir las características clínicas de dichos pacientes. Material y métodos: Se incluyeron pacientes con diagnóstico de FM según criterios ACR 1990 y 2010, en quienes se evalúo la presencia de xerostomía mediante las preguntas correspondientes al dominio de los criterios clasificatorios 2002 ACR-EULAR de Sjögren y se realizó sialometría no estimulada para medición de flujo salival. Resultados: Se reclutaron 50 pacientes, el 100% fueron mujeres. La media de edad fue 47 años (DS+-8,5), siendo la media tiempo de evolución de la FM de 6 años (DS+-4,5). En total 29 pacientes (51%) refirieron xerostomía y de este grupo sólo 4 sialometrías fueron positivas. El tabaquismo fue más prevalente en las pacientes con FM que no referían xerostomía con respecto a las que sí referían xerostomía (31,8 % vs 6,9%, p 0,02), sin encontrarse diferencias estadísticamente significativas en las características clínicas evaluadas. Conclusión: La prevalencia de xerostomía fue del 51%. No se demostró una disminución del flujo salival objetiva en la mayoría de los pacientes con FM.

Introduction: The aim of this study was to determinate the frecuency of xerostomia in patients with diagnosis of Fibromyalgia (FM) and describe their clinical characteristics. Material and methods: Patients were included according 1990 and 2010 ACR Classification criteria. All of them were evaluated for xerostomia and a sialometry was performed in order to determinate the decrease of salival flow. Results: Fifty patients were recruited during the study. The 100% of them were women. The mean age was 47 years old (DS+-8.5), while the mean time of evolution of FM was 6 years (SD +-4.5). Twenty nine patients reported xerostomia of which 4 presented positive sialometry. Smoking was more prevalent in patients with FM who did not report xerostomia with respect of those who reported xerostomia (31.8% vs 6.9%, p 0.02). Conclusion: The frequency of xerostomia was 51%. No statistically significant associations were found in patients who reported xerostomia. A decrease in objective salivary flow was not demonstrated in patients with FM.

How common is dry mouth? systematic review and meta-regression analysis of prevalence estimates

Abstract The aim of this paper is to systematically review the literature to estimate the overall prevalence of xerostomia/hyposalivation in epidemiological studies. An electronic search was carried out up to February 2018 with no language restrictions. A total of 5760 titles were screened and just twenty-nine papers were included in review and the meta-analysis after a two independently reviewers applied the selection criteria. Data were extracted from PubMed and Web of Science databases. Eligibility criteria included original investigations from observational population-based studies that reported the prevalence of xerostomia or data that allowed the calculation of prevalence of xerostomia and/or hyposalivation. Studies conducted in samples with specific health conditions, literature reviews, case reports and anthropological studies, as conferences or comments were excluded. Sample size, geographic location of the study, study design, age of the studied population, diagnosis methods, and evaluation criteria used to determine xerostomia e/or hyposalivation were extracted for meta-analysis and meta-regression. Multivariate meta-regression analysis was performed to explore heterogeneity among studies. The overall estimated prevalence of dry mouth was 22.0% (95%CI 17.0-26.0%). Higher prevalence of xerostomia was observed in studies conducted only with elderly people. Despite diverse approaches to the condition's measurement, just over one in four people suffer from xerostomia, with higher rates observed among older people. Moreover, the measurement methods used currently may over- or underestimate xerostomia. These findings highlight the need for further work on existing and new clinical measure and will be useful to determine which one is more reliable in clinical and epidemiological perspectives.

Resumo O objetivo do estudo é revisar sistematicamente a literatura afim de estimar a prevalência global de xerostomia/hiposalivação em estudos epidemiológicos. Uma busca eletrônica foi conduzida até Fevereiro de 2018 sem restrições de linguagem. Um total de 5760 títulos foram inicialmente identificados e somente vinte e nove artigos foram incluídos na revisão e meta-análise após dois revisores independentes aplicarem os critérios de seleção. Os artigos foram extraídos das bases de dados PubMed/Medline e Web of Science. Os critérios de elegibilidade incluíram investigações originais de estudos observacionais de base populacional os quais reportaram a prevalência de xerostomia ou dados que permitissem o cálculo da prevalência de xerostomia e/ou hiposalivação. Estudos realizados em populações com condições de saúde específicas, revisões de literatura, relato de casos e estudos antropológicos, assim como, conferências ou comentários foram excluídos. Tamanho amostral, localização geográfica aonde foi realizado o estudo, desenho do estudo, idade da população estudada, métodos de diagnóstico e o critério de avaliação para determiner xerostomia e/ou hiposalivação foram extraídos para a meta-análise e metaregressão. Análise de meta-regressão multípla foi realizada para explorar a heterogeneidade entre os estudos. A prevalência global estimada de boca seca foi de 22.0% (95%IC 17.0-26.0%). Uma maior prevalência de xerostomia foi observada em estudos realizados exclusivamente em populações idosas. Apesar de diferentes abordagens utilizadas para mensurar as condições de interesse, cerca de uma em quatro pessoas é acometida por xerostomia, com taxas mais elevadas sendo observadas na população idosa. Além disso, os métodos de mensuração podem ter super- ou subestimado os valores de xerostomia. Os achados do presente estudo salientam a necessidade de mais estudos acerca das existentes e novas formas de avaliação clínica, os quais serão úteis para determinar qual é a mais confiável para as perspectivas clínicas e epidemiológicas.

Early Changes in Apparent Diffusion Coefficient for Salivary Glands during Radiotherapy for Nasopharyngeal Carcinoma Associated with Xerostomia

OBJECTIVE: To evaluate the early changes in the apparent diffusion coefficient (ADC) of the salivary glands during radiotherapy (RT) and their association with the degree of xerostomia at 6 months after RT in patients with nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: We enrolled 26 patients with NPC who underwent RT. Each patient underwent diffusion-weighted MRI of the salivary glands at rest and with gustatory stimulation within 1 week before RT and 2 weeks after the beginning of RT. The ADC at rest (ADCR) and increase and increase rate with stimulation (ADCI, ADCIR) of the submandibular and parotid glands were calculated. The differences in the variables' values between 2 weeks after the beginning of RT and baseline (ΔADCR, ΔADCI, and ΔADCIR) were compared to the degree of xerostomia at 6 months after RT. RESULTS: The ADCR of the submandibular and parotid glands were both significantly higher at 2 weeks after the beginning of RT than found at baseline (both p < 0.01). The ADCI and ADCIR for the parotid glands were both significantly lower at 2 weeks after the beginning of RT than found at baseline (both p < 0.01). ΔADCI and ΔADCIR of the parotid glands were associated with the degree of xerostomia at 6 months after RT (r = −0.61 and −0.72, both p < 0.01). CONCLUSION: The ADCs of the salivary glands change early during RT. The differences in the ADC increase and increase rate of the parotid glands between 2 weeks after the beginning of RT and baseline were associated with the degree of xerostomia at 6 months after RT.

Unusual dental symptoms in Tornwaldt cyst: a case report

@#Tornwaldt (Thornwaldt) or nasopharyngeal cyst is a cyst occurred at the connection site of pharyngeal endoderm and notochord remnant, usually located in the midline postero-superior wall of nasopharynx. Nasopharynx’s obstruction, recurrent infection or trauma may exacerbate mucous secretion by the potential space lining. Although rare and is usually symptomless, it is not uncommon for the patients to have some nasal, ear, cervical or oral symptoms. We report a case of Tornwaldt cyst with rare associated dental symptoms. The patient’s initial presentations were dry mouth, cheek biting, post nasal drip and few nasal symptoms including frequent snoring, sleep apnoea, mouth breathing, sneezing, sore throat and itchiness. These symptoms were tremendously and immediately relieved once the cyst was surgically removed.

Diagnosis and Treatment of Xerostomia / 대한이비인후과학회지

Xerostomia is a subjective sensation of a dry mouth which is frequently encountered in otorhinolaryngologic practice. There are a variety of salivary and nonsalivary causes of xerostomia such as side effects of medication, systemic disorders, radiation and Sjögren's syndrome. The patients with xerostomia have difficulties in chewing, swallowing, speaking, tasting and mataining oral hygiene. Because of the ageing population, and the concomitant increase in medicated individuals, otorhinolaryngologists can expect to be presented with xerostomia in an increasing number of patients in the coming years and therefore should be familiar with its diagnosis and treatment. A systematic approach should be needed to determine the etiology of xerostomia and the management of xerostomia should be multidisciplinary and multimodal. This review summarizes the current literature on the diagnosis, and complications of xerostomia, and on the management of patients with xerostomia.

Menopause and the oral cavity: an oral hygiene update in Indonesia.

Menopause is cessation of menstrual period due to reduced estrogen and progesterone level. Menopause is diagnosed when a woman stops menstruating for at least 1 year. After menopause, women are more susceptible to periodontal diseases. Menopausal women complaining dry mouth should first of all determine salivary gland functions. Adequate salivary function should still maintain oral health. A complete history should be taken in cases of a burning mouth in post-menopausal women, several underlying causes may include psychological disorders, blood glucose, thyroid, and nutritional deficiency associated systemic disorders, and use of ACE inhibitors. In the absence of oral abnormalities, an alternate diagnosis may be Burning Mouth Syndrome. This review gives a general view on cases treated in Indonesia in which such conditions are treated based on the Indonesian Menopause Society (PERMI) guidelines for dental and oral disorders. The Indonesian national consensus concerning this matter necessitates the use of Hormonal therapy after taking a complete history, performing a physical examination, and obtaining patient informed consents. Although usually the domain of dentists, inter specialist cooperation should be encouraged.

Investigation of medicines with potential xerostomic effect used in institutionalized elderly

Introduction: Several factors affect the salivary flow and cause xerostomia, i.e. aging, diets, radiation, various pathologies and the use of drugs. Objective: This study aimed to investigate drugs with potential xerostomic effect in institutionalized elderly patients. Material and methods: 235 elderly were investigated, of both sexes, of which 123 were women (52.3%) and 112 (47.7%) were men. In addition to the gender and age, the use of medications containing side effects of xerostomia/dry mouth/ hyposalivation or hyposialia was investigated. Such drugs were separated according to their medical area of expertise: Cardiology, Gastroenterology, Allergy, Neurology and pulmonology Results: When investigated the amount of drugs used for female patients, it was observed that 83 (67.5%) used up to five drugs, 35 (28.4%) between 6 and 10 and medicines, and 5 (4.1%) more than 10 drugs. When analyzed the amount of drugs used for male patients, it was observed that 88(78.6%) used up to five drugs, 17 (15.2%) were between 6 and 10 7 medicines, and (6.2%) more than 10 drugs. By analyzing the drugs with xerostomic potential, we found 354 medicines. Among these, 181 (51.1%) were used in Neurology, 45 (12.7%) had been prescribed in Cardiology, 33 (9.2%) were used drugs for allergic conditions, 80 (22.3%) were prescribed in gastroenterology and 15 (4.3%) in pulmonology. Conclusion: It can be concluded that many medications used to treat institutionalized elderly had xerostomic potential effect, notably those used in Neurology. Polypharmacy is also present, especially in the older age group.

Consideraciones actuales sobre la xerostomía o síndrome de boca seca / Current considerations on xerostomia or dry mouth syndrome

Las glándulas salivales son glándulas exocrinas, y su función principal es producir saliva. Se distinguen tres pares de glándulas salivales: las parótidas, situadas bajo el oído; las submaxilares, que se localizan en la mandíbula inferior; y las sublinguales, debajo de la lengua. Existen otras de pequeño tamaño dispersas por toda la cavidad bucal, en labios, lengua, etc., las cuales están asociadas al tejido conjuntivo, para captar los nutrientes que necesitan de los vasos sanguíneos, y presentan también conexiones con el propio sistema nervioso. La xerostomía o síndrome de boca seca, se define como la disminución del flujo salival en condiciones de reposo. El origen de esta entidad clínica es multicausal, pudiendo ser el resultado de una alteración localizada sobre las glándulas productoras de la saliva, o bien el resultado de un desequilibrio o alteración de índole sistémica. La evaluación del grado de disfunción de las glándulas salivares ha constituido un objetivo básico para la ciencia en primer lugar. Resulta esencial la elaboración de un historial clínico, acompañado de una entrevista personal al paciente, un examen clínico para el diagnóstico y evaluación de la enfermedad y, entre los exámenes complementarios, las pruebas cuantitativas y cualitativas. Para el tratamiento hay que tener en cuenta la prevención primaria, revisión del tratamiento farmacológico, la estimulación salival, así como los sustitutos de salivas o saliva artificial.

Salivary glands are exocrine glands, and their main function is producing saliva. The three most important pairs of salivary glands are: the parotid ones, located below the ear; the submaxillary ones, located on the lower mandible; and the sublingual ones, located under the tongue. There are several little size others spread out over all the oral cavity, lips, tongue, etc., associated to the conjunctive tissue to capture the nutrients the blood vessels need; they also have connections with the proper nervous system. Xerostomia or the dry mouth syndrome is defined as the decrease of the salivary flow in resting conditions. The origin of this clinical entity is multicausal, and may be the result of an alteration located on the glands producing saliva or the result of a systemic unbalance or modification. Evaluating the dysfunction level of the salivary glands has being a main objective for the science. It is essential to work out a clinical history together with a patient personal interview, a clinical examination for the disease diagnosis and evaluation and, among the complementary tests, the quantitative and qualitative ones. For the treatment, primary prevention, reviewing the pharmacologic treatments, saliva stimulation, and also saliva substitutes or artificial saliva have to be taken into account.

Factors associated to salivary flow alterations in dry mouth female patients / Fatores associados a alterações no fluxo salivar em pacientes com xerostomia

BACKGROUND AND OBJECTIVES: Saliva plays an important role in oral health; it is involved in lubrication of the oral mucosa, protection against infections, transport of nutrients and digestive enzymes, remineralization of teeth, as well as aiding in chewing, swallowing and speech. Reductions in the amount of saliva are known to increase the risk of oral diseases. This study investigated the factors associated to salivary flow alterations and its relationship with age, burning mouth syndrome, psychiatric and sleep disorders, systemic diseases and chronic drug use. METHODS: A total of 30 patients complaining of dry mouth without unbalanced systemic diseases were included. Questionnaires regarding socio-demographic data, xerostomia, burning mouth, depression and anxiety symptoms, and sleep disturbances were applied. Measures of salivary flow rates were obtained using spit method. Correlation of hyposalivation and quantitative data was determined using a multivariate regression model. RESULTS: The age range was 31-83 years, hyposalivation was correlated positively with sleep disorder (β=0.079, 95% CI, to 0,124) and negatively with burning mouth (β=-0.043, 95% CI, -0.083 to -0.002). CONCLUSION: These results provide evidences regarding the association between reduced salivary flow and burning mouth, sleep disorders and chronic use of psychotropic medicines, and we highlighted the important role of antidepressants on modulation of burning mouth sensation...

JUSTIFICATIVA E OBJETIVOS: A saliva tem um papel importante na saúde bucal; está envolvida na lubrificação da mucosa oral, na proteção contra infecções, no transporte de nutrientes e enzimas digestivas, na remineralização dentária e também auxilia na mastigação, deglutição e fala. Sabe-se que reduções na quantidade de saliva aumentam o risco de doenças bucais. Este estudo investigou os fatores associados a alterações no fluxo salivar e seu relacionamento com idade, síndrome de ardência bucal, distúrbios psiquiátricos e do sono, doenças sistêmicas e uso crônico de medicamentos. MÉTODOS: Foi incluído um total de 30 pacientes com queixa de xerostomia sem doenças sistêmicas desequilibradas. Foram aplicados questionários sobre dados sociodemográficos, xerostomia, ardência bucal, sintomas de depressão e ansiedade e distúrbios do sono. As medidas de fluxo salivar foram obtidas pelo método spit. A correlação entre hipo-salivação e dados quantitativos foi determinada por um modelo univariado de regressão. RESULTADOS: A idade various de 31;83 anos, hipo-salivação foi correlacionada positivamente com distúrbios do sono (β=0,079, 95% CI, 0,033 a 0,124) e negativamente com ardência bucal (β=-0,043, 95% CI, -0,083 a -0,002). CONCLUSÃO: Esses resultados trazem evidências sobre a associação entre fluxo salivar reduzido e ardência bucal, distúrbios do sono e uso crônico de psicotrópicos, e destacamos o importante papel dos antidepressivos na modulação da sensação de ardência bucal...

Sjogren's syndrome: An underdiagnosed condition in mixed connective tissue disease

OBJECTIVE: To determine the prevalence of sicca symptoms, dry eye, and secondary Sjögren's syndrome and to evaluate the severity of dry eye in patients with mixed connective tissue disease. METHODS: In total, 44 consecutive patients with mixed connective tissue disease (Kasukawa's criteria) and 41 healthy controls underwent Schirmer's test, a tear film breakup time test, and ocular surface staining to investigate dry eye. In addition, the dry eye severity was graded. Ocular and oral symptoms were assessed using a structured questionnaire. Salivary gland scintigraphy was performed in all patients. Classification of secondary Sjögren's syndrome was assessed according to the American-European Consensus Group criteria. RESULTS: The patients and controls had comparable ages (44.7±12.4 vs. 47.2±12.2 years) and frequencies of female gender (93 vs. 95%) and Caucasian ethnicity (71.4 vs. 85%). Ocular symptoms (47.7 vs. 24.4%) and oral symptoms (52.3 vs. 9.7%) were significantly more frequent in patients than in controls. Fourteen (31.8%) patients fulfilled Sjögren's syndrome criteria, seven of whom (50%) did not have this diagnosis prior to study inclusion. A further comparison of patients with mixed connective tissue disease with or without Sjögren's syndrome revealed that the former presented significantly lower frequencies of polyarthritis and cutaneous involvement than did the patients without Sjögren's syndrome. Moderate to severe dry eye was found in 13 of 14 patients with mixed connective tissue disease and Sjögren's syndrome (92.8%). CONCLUSIONS: Sjögren's syndrome, particularly with moderate to severe dry eye, is frequent in patients with mixed connective tissue disease. These findings alert the physician regarding the importance of the appropriate diagnosis of this syndrome in such patients. .

Association between perception of dry mouth and pre and post-wearing denture satisfaction in the Hansen people / 나학회지

OBJECTIVES: This study investigated on the severity of dry mouth in the hansen people and the association between dry mouth(low, moderate and high) with pre and post wearing denture satisfaction. METHODS: Data were obtained from a cross-sectional survey of 104 hansen people(mean age=69.3). Data were collected by means of a personal interview from April 30 through to Jane 20, 2014. Pre and post wearing denture satisfaction was measured by the 24-items and dry mouth was measured by the 4-items. The data was analysed with t-test, One-way ANOVA, and Logistic regression using the SPSS program. RESULTS: Regarding perception of dry mouth, the subjects achieved a mean of 6.13 out of a maximum 12 points. Scores were categorised as high(8~12), medium(5~7) or low(1~4) and the proportion were 24.5%(9.56), 42.2%(5.81) and 33.3%(4.00) respectively. Those who were older and had fewer natural teeth felt that their perception of dry mouth was more severe. A logistic regression analysis showed that the subjects perception of dry mouth had a significant impact on their gender (OR=2.73), comfort (OR=0.21), aesthetic appreciation (OR=7.56) satisfaction. CONCLUSIONS: Based on the findings, the perception of dry mouth has a significant and negative impact on denture satisfaction. These results suggest that oral health promotion should be considered various factors related dry mouth in the elderly with removable denture.

Association of Glycemic Indexes, Hyposalivation, and Xerostomia Type 1 Diabetic Patients / Asociación de los Índices de Glucemia, Hiposalivación y Xerostomía en Pacientes Diabéticos Tipo 1

The aim of this study was to assess the relationship between glycemic control of type 1 diabetic (DM1) patients and hyposalivation and xerostomia. This observational transversal study used a quantitative approach with a sample of 25 DM1 patients enrolled at the Diabetes Association of Joinville (ADIJO) in 2008. Variables assessed were sialometry through stimulated salivary flow, complaints of xerostomia, and testing for glycemic control: fasting capillary glycemia (FCG) and glycated hemoglobin (HbA1c). The Mann-Whitney U test, chi-square test, and Fisher's exact test were used to verify a possible association among the variables. Most subjects (64 percent; 16/25) showed concomitant hyposalivation and xerostomia. No significant statistical difference between glycemic control (FCG and HbA1c), hyposalivation, and xerostomia (p=0.54) was found. A high prevalence of hyposalivation and xerostomia was found to be more closely related to higher FCG values at the moment of blood testing than to higher values of HbA1c.

El objetivo de este estudio fue evaluar la relación entre el control glucémico de los pacientes diabéticos tipo 1 (DM1) e hiposalivación y xerostomía. Este estudio observacional de cohorte transversal utilizó un enfoque cuantitativo con una muestra de 25 pacientes con DM1 inscritos en la Asociación de Diabetes de Joinville (ADIJO) el 2008. Las variables evaluadas fueron sialometría a través del flujo salival estimulado, quejas de la xerostomía, y las pruebas para el control glucémico: glucosa capilar en ayunas (GCA) y hemoglobina glicosilada (HbA1c). Se utilizaron las pruebas de Mann-Whitney, chi-cuadrado y exacta de Fisher para verificar una posible asociación entre las variables. La mayoría de los sujetos (64 por ciento, 16/25) mostró hiposalivación concomitante y xerostomía. No se observaron diferencias estadísticamente significativas entre el control glucémico (GCA y HbA1c), hiposalivación y xerostomía (p=0,54). Una alta prevalencia de hiposalivación y xerostomía se encontró estrechamente relacionada con los valores altos de GCA mas que con valores altos de HbA1c en el momento del análisis sanguíneo.
