Oral clinical findings and intensive care unit prognostic scores.

OBJECTIVE: Hospitalisation in intensive care unit (ICU) may cause changes in oral environment, which may influence patients' health status. The aim of this study was to evaluate the frequency of intraoral and extraoral findings observed during ICU admission, and to verify if there is an association with clinical prognosis scores. METHODS: Data regarding clinical characteristics of patients hospitalised in an ICU were collected from medical records. The prognostic scores Sepsis Related Organ Failure Assessment (SOFA) and Simplified Acute Physiology Score (SAPS 3) were estimated with data collected from admission and SOFA on the day of the oral examination as well. Data on oral mucosa lesions, saliva, dental condition and oral hygiene were evaluated during oral examinations. RESULTS: The association of oral findings with prognostic scores was statistically verified. The majority (92.2%) of the 170 evaluated patients showed extraoral or intraoral findings during ICU admission. The most frequent findings were chapped and crusted lips, coated tongue, pale mucosa, haemorrhagic lesions, candidiasis, depapillated tongue and traumatic lesions. There were significant higher prognostic scores in the presence of the following extraoral and intraoral findings: crusted and ulcerated lips, haemorrhagic lesions, jaundice, spontaneous oral bleeding, coated and depapillated tongue. Median SAPS 3 was higher in patients with poor oral hygiene. CONCLUSIONS: Oral findings were frequent in the population of patients hospitalised in the ICU and some of them were associated with worse prognostic scores. Routine oral examinations must be performed in hospitalised patients from ICUs for detection of oral markers of worse clinical prognosis.

Prevention and treatment of oral adverse effects of antiresorptive medications for osteoporosis - A position paper of the Brazilian Society of Endocrinology and Metabolism (SBEM), Brazilian Society of Stomatology and Oral Pathology (Sobep), and Brazilian Association for Bone Evaluation and Osteometabolism (Abrasso).

Antiresorptive therapy is the main form of prevention of osteoporotic or fragility fractures. Medication-related osteonecrosis of the jaw (MRONJ) is a relatively rare but severe adverse reaction to antiresorptive and antiangiogenic drugs. Physicians and dentists caring for patients taking these drugs and requiring invasive procedures face a difficult decision because of the potential risk of MRONJ. The aim of this study was to discuss the risk factors for the development of MRONJ and prevention of this complication in patients with osteoporosis taking antiresorptive drugs and requiring invasive dental treatment. For this goal, a task force with representatives from three professional associations was appointed to review the pertinent literature and discuss systemic and local risk factors, prevention of MRONJ in patients with osteoporosis, and management of established MRONJ. Although scarce evidence links the use of antiresorptive agents in the context of osteoporosis to the development of MRONJ, these agents are considered a risk factor for this complication. Despite the rare reports of MRONJ in patients with osteoporosis, the severity of symptoms and impact of MRONJ in the patients' quality of life make it imperative for health care professionals to consider this complication when planning invasive dental procedures.

Oral health status of patients in intensive care unit: a cross-sectional study

Introduction: Patients in intensive care unit (ICU) may present oral alterations asa result of patients' systemic conditions, the use of medications, intubation orpoor oral hygiene. Oral alterations should be detected and treated because theymay aggravate patients' condition. The objective of this study was to evaluate thetypes and frequencies of clinically detected oral alterations in inpatients of an ICU.Methods: This is a cross-sectional study in which an oral evaluation of patientshospitalized in an ICU of a public hospital was performed. Demographic, socialand clinical characteristics were collected from medical records. Oral examswere performed by two trained dentists, with reliability checked by intra-classcorrelation coefficient, while patients were lying in the hospital bed, using a frontalheadlamp, tongue depressor and sterile gauze. All data were recorded in studyprotocol forms and transferred to a data base for analysis. Results: Thirty-sevenpatients, with similar distribution between genders, withmedian age of 62 yearswere evaluated. The most frequent causes for hospitalization were postoperativecare (51.35%) and respiratory problems (29.72%). About 90% of the inpatientspresented some type of oral alterations during the hospitalization period. Themost common clinical alterations were dry lips (86.5%); coated tongue (61.1%);paleness of the oral mucosa (54.1%); oral foci of infection (37.8%) and candidiasis(13.5%). Conclusion: The majority of inpatients of the ICU presented some type oforal alteration, and the most frequent were dry lips and coated tongue. Dataobserved in this study reinforce the need of the dental team support during theperiod of hospitalization.

Mandibular inferior cortical bone thickness on panoramic radiographs in patients using bisphosphonates.

OBJECTIVE: The goal of this study was to detect dimensional changes in the mandibular cortical bone associated with bisphosphonate (BP) use and to correlate measurements of the cortical bone with the cumulative dose of BPs. STUDY DESIGN: Mandibular inferior cortical bone thickness (MICBT) was measured under the mental foramen on panoramic radiographs of patients with and without bisphosphonate-related osteonecrosis of the jaws (BRONJ) taking BPs and controls. RESULTS: Patients with BRONJ had the highest mean MICBT (6.81 ± 1.35 mm), compared with patients without BRONJ taking BPs (5.44 ± 1.09 mm) and controls (4.79 ± 0.85 mm) (P < .01). Mean MICBT of patients with BRONJ was significantly higher than that of patients without BRONJ taking BPs. There was a correlation between MICBT and cumulative dose of zolendronate. CONCLUSIONS: Measurement of MICBT on panoramic radiographs is a potentially useful tool for the detection of dimensional changes associated with BP therapy.

Lactoferrin levels in gingival crevicular fluid and saliva of HIV-infected patients with chronic periodontitis.

AIM: This study compared lactoferrin (LF) levels in the gingival crevicular fluid (GCF) and saliva between HIV-infected and noninfected patients with chronic periodontitis. METHODS: For each subject, LF levels were analyzed in one shallow site (SS; PD ≤3 mm), one deep site (DS; PD >5 mm) and in resting whole saliva. Two groups, 28 HIV-infected and 10 noninfected, were selected. RESULTS: Although the salivary LF levels were higher in HIV-infected than in noninfected individuals, especially in AIDS patients, this was not statistically significant (P > 0.05). Subgingival LF levels for SS and DS were lower among HIV-infected individuals, although AIDS patients showed the lowest levels. Age, smoking, gender, T CD4 lymphocytes levels and viral load did not influence subgingival LF levels, neither for SS nor for DP. Positive fungal culture was observed in 24 HIV-infected patients, but only observed in one in the control group. Overall, LF concentration was significantly higher in DS than SS, both in HIV-infected and noninfected individuals (P < 0.05) and salivary LF levels were always higher than GCF levels. CONCLUSION: The data indicate that LF levels in the GCF and saliva are not different between HIV-infected and noninfected patients with chronic periodontitis.

Candidíase oral em pacientes internados em UTI / Oral candidiasis in patients admitted to ICU

A candidíase oral pode surgir como uma das consequências da má higiene, frequente nos pacientes internados em unidades de terapia intensiva (UTI). Quando disseminada, pode complicar o quadro geral, aumentar o período de internação e levar o paciente ao óbito. O exame oral rotineiro realizado pelo cirurgião-dentista na UTI pode detectar precocemente o quadro de candidíase oral, favorecendo o tratamento e prognóstico. O objetivo deste trabalho é revisar a literatura sobre os dados relacionados à candidíase oral nos pacientes internados em UTI.

Oral candidiasis may develop as a consequence of poor hygiene. It is frequently observed in patients admitted to intensive care units (ICU). Oral candidiasis may disseminate and complicate patient`s condition, increasing the time of hospitalization and mortality rates. Routine oral examination of patients in the ICU will detect early oral candidiasis, favoring treatment and prognosis. The aim of this paper is to review the literature on the data related to oral candidiasis in ICU patients.

Alterações orais em pacientes internados em unidades de terapia intensiva / Oral changes in patients of intensive care units

A internação em Unidades de Terapia Intensiva (UTI) pode provocar alterações orais, que por sua vez podem influenciar o estado de saúde dos pacientes, aumentando o tempo e custo do tratamento hospitalar. O objetivo deste estudo foi realizar uma revisão da literatura sobre as alterações orais encontradas em pacientes de UTI.

Patients hospitalized in intensive care units (ICU) may present changes in the oral environment. The oral alterations may influence the patient's health status, thus increasing the time and cost of hospitalization. The aim of this study is to review the literature on the major oral alterations observed in patients admitted to the ICU.

Randomized double-blind clinical trial comparing clobetasol and dexamethasone for the topical treatment of symptomatic oral chronic graft-versus-host disease.

Patients who undergo allogeneic stem cell transplantation frequently develop an immunologic disease caused by the reactivation of the graft to the host tissues. This disease is called graft-versus-host disease (GVHD) and it is usually a systemic disorder. In a large proportion of cases, oral disorders that are related to a chronic phase of GVHD (cGVHD) occur, and their treatment involves the use of topical immunosuppressive drugs. Several medications have been studied for this purpose, but only a small number of clinical trials have been published. The present study is a randomized, double-blind clinical trial that compares topical clobetasol and dexamethasone for the treatment of symptomatic oral cGVHD. Patients were randomly assigned to treatment with clobetasol propionate .05% or dexamethasone .1 mg/mL for 28 days. In both arms, nystatin 100,000 IU/mL was administered with the corticosteroid. Oral lesions were evaluated by the modified oral mucositis rating scale (mOMRS) and symptoms were registered using a visual analogue scale. Thirty-five patients were recruited, and 32 patients were randomized into the study groups: 18 patients (56.3%) to the dexamethasone group and 14 patients (43.8%) to the clobetasol group. The use of clobetasol resulted in a significant reduction in mOMRS total score (P = .04) and in the score for ulcers (P = .03). In both groups, there was significant symptomatic improvement but the response was significantly greater in the clobetasol group (P = .02). In conclusion, clobetasol was significantly more effective than dexamethasone for the amelioration of symptoms and clinical aspects of oral lesions in cGVHD.

Oral status of patients submitted to autologous hematopoietic stem cell transplantation.

PURPOSE: Oral infection may be a source of bacteremia in patients undergoing hematopoietic stem cell transplant (HSCT). The aim of this study was to evaluate the relationship between patients with poor periodontal status and complications after HSCT. METHODS: A cohort of patients with hematological malignancies candidates for autologous HSCT was observed before and during the neutropenic phase of HSCT. A primary evaluation was performed before the HSCT procedure, including medical and socio-demographic data and physical examination (number of teeth and decayed, missing and filled teeth index (DMFT), oral mucosa, and full mouth periodontal assessment). During the neutropenic phase, data regarding the development of febrile neutropenia, bacteremia, and mucositis were also prospectively obtained. RESULTS: Forty-eight patients were included. The most common baseline disease was multiple myeloma (70 %). In the primary evaluations, the median DMFT was 13 (ranging 0-27), and periodontitis and gingivitis were present in 29 and 60 % of the patients, respectively. During the neutropenic phase of HSCT, fever occurred in 96 % of patients, and bacteremia was documented in 29 %. Coagulase-negative Staphylococcus was the most common isolated bacteria. Patients who developed bacteremia had a higher frequency of oral disorders compared with those without bacteremia, but it was not statistically significant. Oral mucositis affected 89.6 % of the patients, and patients with gingivitis or periodontal disorders had a high frequency of mucositis. CONCLUSIONS: The prevalence of oral pathologic conditions previous to HSCT procedures was very high in the studied population. A possible association was noted between previous gingivitis and the development of mucositis during the neutropenia of HSCT.

Mandibular cortical bone evaluation on cone beam computed tomography images of patients with bisphosphonate-related osteonecrosis of the jaw.

OBJECTIVES: The objective of this study was to develop a technique for detecting cortical bone dimensional changes in patients with bisphosphonate-related osteonecrosis of the jaw (BRONJ). STUDY DESIGN: Subjects with BRONJ who had cone-beam computed tomography imaging were selected, with age- and gender-matched controls. Mandibular cortical bone measurements to detect bisphosphonate-related cortical bone changes were made inferior to mental foramen, in 3 different ways: within a fixed sized rectangle, in a rectangle varying with the cortical height, and a ratio between area and height. RESULTS: Twelve BRONJ cases and 66 controls were evaluated. The cortical bone measurements were significantly higher in cases than controls for all 3 techniques. The bone measurements were strongly associated with BRONJ case status (odds ratio 3.36-7.84). The inter-rater reliability coefficients were high for all techniques (0.71-0.90). CONCLUSIONS: Mandibular cortical bone measurement is a potentially useful tool in the detection of bone dimensional changes caused by bisphosphonates.

Oral involvement of chronic graft-versus-host disease in hematopoietic stem cell transplant recipients.

Oral manifestations are common in patients who are diagnosed with chronic graft-versus-host-disease (cGVHD). These manifestations can present as oral mucosal lesions, salivary gland dysfunction, or reduction of the mouth opening due to cutaneous sclerosis. Although several studies have reported the prevalence of oral involvement in cGVHD, few have reported details of different types and severity of oral lesions of cGVHD, according to the NIH. Furthermore, the authors are aware of only one published study concerning oral manifestations of cGVHD in Brazil. The purpose of this study was to evaluate the prevalence and severity of oral involvement of cGVHD. Oral evaluation of hematopoietic stem cell transplant (HSCT) recipients was conducted on 22 patients (12 men and 10 women) from December 2007 to May 2009. The following categories were assessed: Age, gender, underlying disease, time postHSCT, history of GVHD, therapy for GVHD, oral lesions, xerostomia, resting salivary flow rate, and mouth opening. Oral lesions were classified according to NIH criteria, and the results were submitted to a descriptive analysis. According to the NIH, patients presented diagnostic (40.9%), distinctive (31.9%), and common (9.1%) features of oral cGVHD. Oral involvement of cGVHD was identified in 81.8% of patients, 68.2% as mucosal lesions and 59.1% as salivary gland dysfunction. Reduced mouth opening was observed in 12 patients (80%), with one case associated with cutaneous sclerosis. Oral involvement was frequent in these patients; for many, it was the first clinical manifestation of cGVHD.

Recurrent bilateral gingival peripheral calcifying epithelial odontogenic tumor (Pindborg tumor): a case report.

Calcifying epithelial odontogenic tumor (CEOT) is an extremely rare, benign neoplasm, accounting for approximately 1% of all odontogenic tumors. Peripheral CEOTs commonly resemble oral hyperplastic or reactive lesions and are histologically similar to their intraosseous counterparts. We report an unusual case of multifocal peripheral CEOT. A 40-year-old female presented with bilateral soft, painful, erythematous, gingival swellings localized in premolar areas of the mandibular gingiva. The presumptive diagnosis was bilateral pyogenic granuloma. The masses were surgically excised under local anesthesia without bone curettage and both recurred 12 months later. Morphologic features, and histochemical and immunohistochemical tests revealed bilateral peripheral calcifying odontogenic epithelial tumor. There is no clinical or radiographic evidence of recurrence 3.5 years after excision. This multifocal phenomenon has been reported previously only for intraosseous CEOT. Gingival masses must be carefully evaluated for clinical and histologic evidence of neoplasia.

Salivary histatin-5 and oral fungal colonisation in HIV+ individuals.

The oral cavity is a primary target for opportunistic infections, particularly oral candidiasis caused by the opportunistic pathogen Candida albicans. HIV+ individuals constitute a population highly susceptible to oral candidiasis possibly due to a change in the environment of the oral cavity as the result of salivary gland dysfunction. Histatins are a family of salivary antimicrobial peptides which under normal circumstances have a protective function on the oral mucosa. This study aimed to compare salivary histatin concentrations and oral fungal colonisation in an HIV+ and HIV- control populations. Oral samples for fungal cultures and parotid saliva were collected from all subjects. Fungal identification was determined using standard mycological procedures. In order to determine salivary histatin levels a semi-quantitative ELISA was designed using a specific polyclonal antibody and extensive statistical analysis was performed. Forty-seven percent of HIV+ and 17% of control subjects had positive fungal cultures. Mean histatin levels were 7.32 microg ml(-1) for the HIV+ group and 9.17 microg ml(-1) for control group (P = 0.003). The data from this study demonstrate that the level of fungal colonisation is significantly higher in HIV+ individuals whereas histatin-5 concentrations are significantly lower, likely contributing to the enhanced predisposition of this population to oral candidiasis.

Prevalence of oral Candida species ina North American pediatric population.

Oral candidiasis caused by species other than Candida albicans has been observed. This study evaluated the prevalence of oral yeast species among 196 children during routine oral exam. Based on standard mycological testing, 130 (66%) subjects had fungal growth. Candida albicans isolates were recovered in 56% of children, but an extensive diversity in the non-albicans species was observed. Intrinsic differences in the pediatric population may favor the presence of yeast species other than C. albicans.

Involvement of steroids in anti-inflammatory effects of peripheral benzodiazepine receptor ligands.

Mouse paw oedema induced by carrageenan is used to determine if glucocorticoids are involved in the anti-inflammatory effects of peripheral benzodiazepine receptor ligands. The anti-inflammatory responses elicited by i.p. treatment with 1-(2-chlorophenyl)-N-methyl-N (1-methyl-propyl)-3-isoquinoline carboxamide (PK11195) and 7-chloro-5-(4-chlorophenyl)-1,3-dihydro-1-methyl-2-H-1, 4-benzodiazepin-2 (Ro5-4864) were reversed by aminoglutethimide, an inhibitor of steroidal synthesis. Intraplantar injection into the ipsilateral paw of Ro5-4864, but not PK11195, inhibited the formation of paw oedema and this effect was reversed by aminoglutethimide. These results suggest that glucocorticoids are involved in the systemic and local anti-inflammatory effects of Ro5-4864 and only in the systemic response to PK11195.

Relationship between salivary flow rates and Candida counts in subjects with xerostomia.

OBJECTIVE: This study evaluated the relationship between salivary flow and Candida colony counts in the saliva of patients with xerostomia. STUDY DESIGN: Sialometry and Candida colony-forming unit (CFU) counts were taken from 112 subjects who reported xerostomia in a questionnaire. Chewing-stimulated whole saliva was collected and streaked in Candida plates and counted in 72 hours. Species identification was accomplished under standard methods. RESULTS: There was a significant inverse relationship between salivary flow and Candida CFU counts (P =.007) when subjects with high colony counts were analyzed (cutoff point of 400 or greater CFU/mL). In addition, the median sialometry of men was significantly greater than that of women (P =.003), even after controlling for confounding variables like underlying disease and medications. Sjögren's syndrome was associated with low salivary flow rate (P =.007). There was no relationship between the median Candida CFU counts and gender or age. There was a high frequency (28%) of mixed colonization. Candida albicans was the most frequent species, followed by C parapsilosis, C tropicalis, and C krusei. CONCLUSIONS: In subjects with high Candida CFU counts there was an inverse relationship between salivary flow and Candida CFU counts.
