Epidemiology of Severity of Temporomandibular Disorders in Brazilian Women

Aims: To evaluate the severity of temporomandibular disorders (TMD) of women in the municipality of Araraquara (Brazil) as well as the contribution of the perception of oral health, mandibular functional limitation, and sociodemographic variables on the severity of TMD. Methods: The participants were interviewed by telephone. Information regarding age, marital status, economic level, education, and use and type of dental prostheses was surveyed. To evaluate TMD severity, mandibular functional limitation and perception of oral health, Fonseca's Anamnesic Index (IAF), the Mandibular Function Impairment Questionnaire (MFIQ), and the General Oral Health Assessment Index (GOHAI) were used. To evaluate the contribution of these variables on TMD severity, a structural equation model (SEM) was fitted to the data and assessed by usual goodness-of-fit indices. Results: A total of 701 women with a mean age of 44.36 years (SD = 16.31) participated. According to the IAF, 59.6% (95% confidence interval = 56.00%-63.2%) of the women were classified as having TMD, of which 63.9% presented light, 26.8% moderate, and 9.3% severe TMD. Mandibular functional limitation was low in 91.0% of the women, moderate in 7.1%, and severe in 1.9%. Goodness-of-fit for the structural model was adequate. The predictors explained 43% of the variation in the TMD severity, with significant contributions of the variables dental prostheses (beta = -.008; P = .006), perception of oral health (beta = -.43; P < .001), and mandibular functional limitation (beta = .014; P = 014). Conclusion: The severity of TMD among Brazilian women was greater in non-users of dental prostheses and was also associated with greater mandibular functional limitation and poor perception of oral health.

Hipoparatireoidismo primário em cão

The hypoparathyroidism is a rare endocrinopathy reported in dogs, caused by a deficiency in the synthesis of parathyroid hormone (PTH). The lack of PTH causes hypocalcemia and hyperphosphatemia, resulting in a series of neurological and neuromuscular disorders. Unlike most endocrinopathies, hypoparathyroidism is a disease in which the exogenous hormone replacement is not being viable, becoming the treatment a challenge. The present report aims to describe a case of primary hypoparathyroidism in a Schnauzer dog with seizures and neuromuscular disorders, and successful treatment employed, this being the first case, according to the literature, of hypoparathyroidism diagnosed in Brazil. The hypoparathyroidism should be considered as a differential diagnosis in cases of seizure. A complete neurological evaluation and determination of serum ionized calcium and parathyroid hormone are essential for the diagnosis of this disease. Early diagnosis may improve the quality of life of affected animals, since after the initiation of therapy, there is complete remission of clinical signs.

Glioma misto em um cão: relato de caso

Intracranial neoplasms are common causes of neurological disorders in middle-aged and elderly dogs. With the feasibility of computed tomography, it is now possible to determine the extent and exact location of brain tumors, identifying them ante mortem in dogs and cats. This paper aims to report the occurrence of a mixed glioma in a Boxer dog examined at the Veterinary Hospital of Unesp, Botucatu Campus. The animal presented with a brain syndrome of acute onset and progressive course. CT scan showed the presence of a mass in the right cerebral hemisphere extending from the frontal to the parietal region and involving the basal ganglia. Given the gravity of the neurological disorder, the owner chose to perform euthanasia. Microscopic analysis of the mass allowed the diagnosis of mixed glioma.

Co-existence of t(6;13)(p21;q14.1) and trisomy 12 in chronic lymphocytic leukemia

We report a case of a 57-year-old man diagnosed with chronic lymphocytic leukemia (CLL) and presence of a rare t(6;13)(p21;q14.1) in association with an extra copy of chromosome 12. Classical cytogenetic analysis using the immunostimulatory combination of DSP30 and IL-2 showed the karyotype 47,XY,t(6;13)(p21;q14.1), +12 in 75% of the metaphase cells. Spectral karyotype analysis (SKY) confirmed the abnormality previously seen by G-banding. Additionally, interphase fluorescence in situ hybridization using an LSI CEP 12 probe performed on peripheral blood cells without any stimulant agent showed trisomy of chromosome 12 in 67% of analyzed cells (134/200). To the best of our knowledge, the association of t(6;13)(p21;q14.1) and +12 in CLL has never been described. The prognostic significance of these new findings in CLL remains to be elucidated. However, the patient has been followed up since 2009 without any therapeutic intervention and has so far remained stable.

Differential aberrant sprouting in temporal lobe epilepsy with psychiatric co-morbidities

Psychiatric co-morbidities in epilepsy are common in patients with temporal lobe epilepsy (TLE). Pathological alterations in TLE are well characterised; however, neuropathologic data are relatively scale regarding the association between psychiatric diseases and epilepsy. Our objective was to evaluate the clinical data of 46 adult TLE patients with and without psychiatric co-morbidities and to correlate the data with hippocampal neuronal density and mossy fiber sprouting. Accordingly, patients were grouped as follows: TLE patients without history of psychiatric disorder (TLE, n = 16), TLE patients with interictal psychosis (TLE + P, n = 14), and TLE patients with major depression (TLE + D, n = 16). Hippocampi from autopsies served as non-epileptic controls (n = 10). TLE + P exhibited significantly diminished mossy fiber sprouting and decreased neuronal density in the entorhinal cortex when compared with TLE. TLE + P showed significantly poorer results in verbal memory tasks. TLE + D exhibited significantly increased mossy fiber sprouting length when compared with TLE and TLE + P. Further, a higher proportion of TLE + D and TLE + P presented secondarily generalised seizures than did TLE. Our results indicate that TLE patients with psychiatric disorders have distinct features when compared with TLE patients without psychiatric co-morbidities and that these changes may be involved in either the manifestation or the maintenance of psychiatric co-morbidities in epilepsy.

THE ASSOCIATION BETWEEN CHILDHOOD ADVERSITY AND COMPONENTS OF METABOLIC SYNDROME IN ADULTS WITH MOOD DISORDERS: RESULTS FROM THE INTERNATIONAL MOOD DISORDERS COLLABORATIVE PROJECT

Objective: We sought to determine whether a reported history of childhood adversity is associated with components of the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP-III)-defined metabolic syndrome in adults with mood disorders. Method: This was a cross-sectional analysis of adult outpatients (N = 373; n = 230 female, n = 143 male; mean age [SD] = 42.86 [14.43]) from the International Mood Disorders Collaborative Project (University of Toronto and Cleveland Clinic) with DSM-IV-defined major depressive disorder and bipolar I/II disorder. Childhood adversity was measured with the Klein Trauma & Abuse-Neglect self-report scale. The groups with and without childhood adversity were compared to determine possible differences in the rates of metabolic syndrome and its components. Logistic and linear regressions adjusted for age, sex, education, employment status, and smoking were used to evaluate the association between childhood adversity and components of metabolic syndrome. Results: For the full sample, 83 subjects (22.25%) met criteria for metabolic syndrome. Individuals reporting a history of any childhood adversity had higher systolic and diastolic blood pressure (systolic: p = 0.040; diastolic: p = 0.038). Among subjects with a history of sexual abuse, a significant proportion met criteria for obesity (45.28% vs. 32.88%; p = 0.010); a trend toward overweight was found for subjects with a history of physical abuse (76.32% vs. 63.33%; p = 0.074), although this relationship did not remain significant after adjusting for potential confounders. There was no statistically significant difference in the overall rate of dyslipidemia and/or metabolic syndrome between subjects with and without childhood adversity. Conclusion: The results herein provide preliminary evidence suggesting that childhood adversity is associated with metabolic syndrome components in individuals with mood disorders. Int'l. J.

Accuracy of Screening for Potentially Malignant Disorders of the Oral Mucosa by Dentists in Primary Care

Purpose: To examine the accuracy of a screening programme for potentially malignant disorders of the oral mucosa by visual inspection in primary health care. Materials and Methods: The study was based on secondary data from the Primary Care Information System maintained by seven units of family health in Sao Paulo City managed by a non-governmental agency. The reference population was composed of 15,072 residents 50 years old or more of both genders. The study population comprised 2,980 individuals. During screening in community settings, the oral mucosa was examined by trained dentists and distributed into two categories: (a) screen negative (b) screen positive. All participants underwent comprehensive clinical exams by a general dental practitioner supervised by a specialist. Individual records were grouped in a working dataset. Point and 95% confidence interval estimates were calculated regarding measures of sensitivity (Se), specificity (Sp) and positive and negative predictive values (PPV and NPV, respectively). Results: 18.0% of the population was considered screen positive. A total of 133 lesions (4.5%) were identified and 8 cases of oral cancer were confirmed, which corresponded to a prevalence rate of 27 cases in 10,000 people, a much higher rate than expected. The measures found were Se: 91.7% (85.3-95.6), Sp: 85.4% (84.1-86.7), PPV: 22.7% (19.3-26.5), NPV: 99.5% (99.2-99.8). The visual screen presented high accuracy. Conclusion: The test presented high sensibility and specificity values. From a public health point of view, the high accuracy levels showed the importance of oral health teams on family health strategy for more comprehensive primary care. Targeting risk groups and delegating the screening to community health agents may improve PPV and coverage.

A step forwards in immunomodulation and immunetolerance knowledge. HLA-G expression in co-cultures of peripheral blood mononuclear cells and stem cells after in vitro NGAL stimulation

NGAL (Neutrophil Gelatinase-associated Lipocalin ) is a protein of lipocalin superfamily. Recent literature focused on its biomarkers function in several pathological condition (acute and chronic kidney damage, autoimmune disease, malignancy). NGAL biological role is not well elucidated. Several are the demonstration of its bacteriostatic role. Recent papers have indeed highlight NGAL role in NFkB modulation. The aim of this study is to understand whether NGAL may exert a role in the activation (modulation) of T cell response through the regulation of HLA-G complex, a mediator of tolerance. From 8 healthy donors we obtained peripheral blood mononuclear cells (PBMCs) and we isolated by centrifugation on a Ficoll gradient. Cells were then treated with four concentrations of NGAL (40-320 ng/ml) with or without iron. We performed flow cytometry analysis and ELISA test. NGAL increased the HLA-G expression on CD4+ T cells, with an increasing corresponding to the dose. Iron effect is not of unique interpretation. NGAL adiction affects regulatory T cells increasing in vitro expansion of CD4+ CD25+ FoxP3+ cells. Neutralizing antibody against NGAL decreased HLA-G expression and reduced significantly CD4+ CD25+ FoxP3+ cells percentage. In conclusion, we provided in vitro evidence of NGAL involvement in cellular immunity. The potential role of NGAL as an immunomodulatory molecule has been evaluated: it has been shown that NGAL plays a pivotal role in the induction of immune tolerance up regulating HLA-G and T regulatory cells expression in healthy donors. As potential future scenario we highlight the in vivo role of NGAL in immunology and immunomodulation, and its possible relationship with immunosuppressive therapy efficacy, tolerance induction in transplant patients, and/or in other immunological disorders.
