Excision of an atypical case of palatal bone exostosis: a case report.

Bone exostosis has long been described in the literature, appearing in most cases as a torus palatinus or mandibularis. These two variations are relatively common and affect approximately 30% of the world's population. Incidence is even higher when human skulls are examined post mortem, indicating that in some cases the exostosis is small and cannot be seen under the soft tissue. Removal of an exostosis is usually associated with the construction of a prothesis, but in rare cases such as the present, the lesion enlarges enough to affect speech and feeding. Few studies have reported the removal of such a large exostosis, and all were conducted in a hospital environment. In this case, complete removal was successfully conducted in an ambulatory clinic under local anesthesia.

Parâmetros genéticos, tendências e resposta à seleção de características produtivas da raça Nelore na Amazônia Legal

O objetivo deste trabalho foi estimar parâmetros genéticos (herdabilidades e correlações), efeitos não genéticos, tendência genética e resposta à seleção para as características de crescimento (pesos padronizados aos 120, 210 e 450 dias) e características reprodutivas (idade ao primeiro parto e perímetro escrotal aos 450 dias) de machos e fêmeas, da raça Nelore criados na Amazônia Legal. O arquivo de dados analisado consistia em 211.744 registros de animais da raça Nelore, participantes do Programa de Melhoramento Genético da Raça Nelore (PMGRN- Nelore Brasil), nascidos no período de 1995 e 2008, distribuídos em rebanhos localizados nos estados do AC, MA, MT, PA, RO e TO. A consistência dos dados, as análises descritivas, de variância e de escolha do modelo para cada uma das características foram realizadas utilizando-se o software Statistical Analysis System. As estimativas de média e desvio padrão foram de 122,919,0; 179,628,1; 262,445,5; 227,229,2; 37,14,7, respectivamente para as características de P120, P210, P450, PE450 e IPP. As herdabilidades para P120 foram de 0,24; 0,21 e 0,36, para h²d, h²m e h²t, respectivamente; para P210 foram de 0,29; 0,16 e 0,45, para h²d, h²m e h²t, respectivamente e para P450, PE450 e IPP, foram de 0,48; 0,49 e 0,22, respectivamente. As correlações genéticas entre os pesos variaram de 0,51 a 0,78, entre os pesos e PE450 variaram de 0,26 a 0,46, entre os pesos e a IPP foram baixas e negativas e entre PE450 e IPP foi nula. Em todas as características estudadas, os progressos genéticos foram superiores aos fenotípicos, com exceção à IPP. Os resultados de resposta à seleção variaram de 0,27 a 0,11 kg/ano; 0,49 a 0,20 kg/ano; 1,32 a 0,53 kg/ano; 0,08 a 0,03 cm/ano e 0,06 a 0,02 dias/ano para P120, P210, P450, PE450 e IPP, respectivamente. Portanto, todas as características estudadas podem ser utilizadas como critério de seleção, objetivando melhorar a produtividade.

Cystatin C is independently associated with total and cardiovascular mortality in individuals undergoing coronary angiography. The Ludwigshafen Risk and Cardiovascular Health (LURIC) study.

AIMS Cystatin C is a well established marker of kidney function. There is evidence that cystatin C concentrations are also associated with mortality. The present analysis prospectively evaluated the associations of cystatin C with all-cause and cardiovascular (CV) mortality in a well-characterized cohort of persons undergoing angiography, but without overt renal insufficiency. METHODS Cystatin C was available in 2998 persons (mean age: 62.7 ± 10.5 years; 30.3% women). Of those 2346 suffered from coronary artery disease (CAD) and 652 (controls) did not. Creatinine (mean ± SD: 83.1 ± 47.8 vs. 74.1 ± 24.7 μmol/L, p = 0.036) but not Cystatin C (mean ± SD: 1.02 ± 0.44 vs. 0.92 ± 0.26 mg/L, p = 0.065) was significantly higher in patients with CAD. After a median follow-up of 9.9 years, in total 898 (30%) deaths occurred, 554 (18.5%) due to CV disease and 326 (10.9%) due to non-CV causes. Multivariable-adjusted Cox analysis (adjusting for eGFR and established cardiovascular risk factors, lipid lowering therapy, angiographic coronary artery disease, and C-reactive protein) revealed that patients in the highest cystatin C quartile were at an increased risk for all-cause (hazard ratio (HR) 1.93, 95% CI 1.50-2.48) and CV mortality (HR 2.05 95% CI 1.48-2.84) compared to those in the lowest quartile. The addition of cystatin C to a model consisting of established cardiovascular risk factors increased the area under the receiver-operating characteristic curve for CV and all-cause mortality, but the difference was statistically not significant. However, reclassification analysis revealed significant improvement by addition of cystatin C for CV and all-cause mortality (p < 0.001), respectively. CONCLUSION The concentration of cystatin C is strongly associated with long-term all-cause and cardiovascular mortality in patients referred to coronary angiography, irrespective of creatinine-based renal function.

Monogenic Human Skin Disorders

Human genodermatoses represent a broad and partly confusing spectrum of countless rare diseases with confluent and overlapping phenotypes often impeding a precise diagnosis in an affected individual. High-throughput sequencing techniques have expedited the identification of novel genes and have dramatically simplified the establishment of genetic diagnoses in such heterogeneous disorders. The precise genetic diagnosis of a skin disorder is crucial for the appropriate counselling of patients and their relatives regarding the course of the disease, prognosis and recurrence risks. Understanding the underlying pathophysiology is a prerequisite to understanding the disease and developing specific, targeted or individualized therapeutic approaches. We aimed to create a comprehensive overview of human genodermatoses and their respective genetic aetiology known to date. We hope this may represent a useful tool in guiding dermatologists towards genetic diagnoses, providing patients with individual knowledge on the respective disorder and applying novel research findings to clinical practice.
