Frequency of multiple endocrine neoplasia type 1 in a group of patients with pituitary adenoma: genetic study and familial screening

The purpose of this study it was to evaluate the frequency of Multiple Endocrine Neoplasia type 1 (MEN1) in patients with pituitary adenoma and to perform genetic analysis and familial screening of those individuals afflicted with MEN1. 144 patients with pituitary adenoma at Botucatu Medical School, UNESP-Univ Estadual Paulista, were assessed retrospectively for MEN1 during the years of 2005-2011. The patients were evaluated for the presence of primary hyperparathyroidism (PHP) and enteropancreatic tumors. Genetic analysis was performed for the individuals with clinically diagnosed MEN1. Thirteen patients met the diagnostic criteria for MEN1, but three individuals belong to the same family and they were considered as a single MEN1 event, revealing 7.7 % frequency of MEN1 in this patient group. Genetic analysis showed MEN1 mutations in four index cases: IVS4+1 G>A, IVS3-6 C>T, c.1547insC and a new D180A mutation. One patient did not agree to participate in the genetic study and another one was referred for follow up in other hospital. Only polymorphisms were found in the other individuals, one of which was novel. We identified a high frequency of MEN1 in pituitary adenoma patients. Since PHP is one of the most common MEN1 tumor and patients are mostly asymptomatic, we suggest that all pituitary adenoma patients have their calcium profile analyzed. © 2013 Springer Science+Business Media New York.

Perfil da fluência: análise comparativa entre gagueira desenvolvimental persistente familial e isolada

PURPOSE: to evaluate and compare the fluency between the familial and the sporadic persistent developmental stuttering, characterizing the typology and the frequency of the disfluencies, the speech rate and the severity of the stuttering. METHOD: 40 participants aged from 6 to 42 years old, divided in two groups with twenty participants in each one: Familial Persistent Developmental Stuttering and Sporadic Persistent Developmental Stuttering. The procedures used were: clinical and familial history, assessment of fluency and Stuttering Severity Instrument. RESULTS: there were no statistically significant differences between the groups regarding the frequency of stuttering like disfluencies, the flow of syllables and words per minute and the severity of stuttering. It was noted a tendency of the group with familial stuttering to show a bigger variability of the severity of stuttering, going from mild to very severe, whereas in the group with sporadic stuttering, the severity varied from mild to severe. CONCLUSION: this study represents the first effort to the characterization of the speech fluency profile of the subgroups of people who stutter, namely familial persistent developmental stuttering and sporadic persistent developmental stuttering. It is possible to conclude that the speech fluency profile of people who stutter, independently of the familial history, is similar. It is noteworthy that the occurrence of some stuttering-like disfluencies, monosyllabic word repetition, block and intrusion were different between groups.

Estudos moleculares das regiões cromossômicas 7q31 e 7q34 em portadores de gagueira persistente familial

A gagueira é um distúrbio no ritmo da fala no qual o indivíduo sabe precisamente o que quer dizer, mas ao mesmo tempo é incapaz de dizê-lo devido à repetição involuntária, ao prolongamento ou à cessação do som. Este distúrbio da comunicação acomete cerca de 1 a 2 % da população mundial, e esta freqüência varia de acordo com a idade, sendo mais comum em crianças com idade pré-escolar (de 2,4 a 5%); e com o sexo (3 M : 1 F). Desde a década de 50 a gagueira vem sendo estudada por fonoaudiólogos e geneticistas. Vários fatores são tidos na literatura como de risco para o desenvolvimento da gagueira persistente, dentre os quais destacamos: idade, sexo, tipo e tempo de duração das disfluências, outros distúrbios fonoaudiológicos, características secundárias, fatores genéticos, comportamentos familiares e outros. Desta forma, a gagueira não deve ser tratada como uma entidade nosológica única, pois apresenta característica multidimensional e multifatorial. Dentre os principais fatores que sugerem etiologia genética para a gagueira destacamos: 1)Gagueira presente em agregados familiais; 2)Maior probabilidade de se desenvolver em indivíduos consanguíneos; 3)Semelhança dos traços fenotípicos característicos, independente da língua e cultura; 4)Maior concordância entre gêmeos monozigóticos do que em gêmeos dizigóticos. A triagem genômica em famílias de gagos provenientes do Paquistão, e dos Estados Unidos, Suécia e Israel indicaram uma possível ligação da gagueira com o cromossomo 7. O objetivo deste trabalho foi a análise de ligação nas regiões cromossômicas 7q31 e 7q34 através de marcadores microssatélites em 31 famílias brasileiras com gagueira persistente, com mais de um indivíduo gago em idade acima de 6 anos. Utilizou-se para a classificação da gagueira, o SSI aplicado por profissionais especializados nesta disfluência... (Resumo completo, clicar acesso eletrônico abaixo)

Guidelines for the management and treatment of periodic fever syndromes Familial Mediterranean Fever

To establish guidelines based on scientific evidence for the management of familial Mediterranean fever. The Guideline was prepared from 5 clinical questions that were structured through PICO (Patient, Intervention or indicator, Comparison and Outcome), to search in key primary scientific information databases. After defining the potential studies to support the recommendations, these were graduated considering their strength of evidence and grade of recommendation. 10,341 articles were retrieved and evaluated by title and abstract; from these, 46 articles were selected to support the recommendations. 1. The diagnosis of FMF is based on clinical manifestations, characterized by recurrent febrile episodes associated with abdominal pain, chest or arthritis of large joints; 2. FMF is a genetic disease presenting an autosomal recessive trait, caused by mutation in the MEFV gene; 3. Laboratory tests are not specific, demonstrating high serum levels of inflammatory proteins in the acute phase of the disease, but also often showing high levels even between attacks. SAA serum levels may be especially useful in monitoring the effectiveness of treatment; 4. The therapy of choice is colchicine; this drug has proven effectiveness in preventing acute inflammatory episodes and progression towards amyloidosis in adults; 5. Based on the available information, the use of biological drugs appears to be an alternative for patients with FMF who do not respond or are intolerant to therapy with colchicine.

Effects of Statin and Aerobic Physical Exercise Association in the Cardiomyocytes of the Rat. Morphometric Study

Physical exercise and statins, recommended interventions to dyslipidaemia treatment, are independently related to cardiomyocytes alterations, characterized by miocardic hypertrophy and apoptosis, respectively. Thus, the objective of the present study was to analyze the effects of statin and aerobic physical exercise association in the morphometric parameters of cardiac cell nucleus. 40 male rats adults were divided into four groups: exercised (DE); sedentary (DS), exercised and statin use (DES); sedentary and statin use (DSS). The animals received during the whole experimental period a hiperlipidic diet added 20% of coconut oil and 1.25% of cholesterol; after 30 days of its ingestion, a blood collection was made to verify the dyslipidaemia. Simvastatin (20 mg) was taken five days a week, during eight weeks. During this period, the animals exercised 60 minutes daily in the treadmill. After the last day of the protocol, the cardiac muscle was collected and maintained in liquid nitrogen (-180 degrees C); the cuts were stained by Hematoxilin-Eosin method, and the cardiac fibers were submitted to the nuclear morphometric analyses. The data were analyzed using descriptive analyses, paired T test, Kruskal-Wallis test and Dunn post hoc test; for all analyses, it was adopted p<0.05. It was verified that the group receiving statin presented values statistically significant in comparison to the other groups, in the tridimensional and linear variables. The exercised and statin group, the values obtained in the morphometric analyses were similar to the control group. It is suggested that statins alone can cause alterations in the nucleus of cardiac cells that can be related to apoptosis occurrence and, when exercise is practiced associated to statin administration, the effects of statin can be reduced, what can be related to beneficial adaptations of cardiac mitochondrial in response to physical exercise, turning them more resistant to apoptotic stimuli.

Meningeal tumor: A rare extrahepatic association in patients with polycystic liver disease enrolled for liver transplantation

In the present study, we described a rare association of polycystic liver disease (PCLD) with intracranial meningiomas in patients included on a liver transplant list, focusing on the diagnosis, treatment and possible association with any genetic alterations. Two female patients, aged 39 and 49 years were included on a liver transplant list due to extensive PCLD, with symptoms related to an abdominal compartmental syndrome. Screening for extrahepatic manifestation revealed a right frontal meningioma in the first patient, and a parietal posterior calcified meningioma in the second patient, measuring 1 and 7x3x2 cm in diameter, respectively. Following tumor removal, the histological pattern was compatible with fibrous and transitional meningioma, respectively. Cytogenetic studies conducted following surgery did not reveal any changes in metaphase chromosomes. The postoperative follow-up for the two patients was uneventful, without complications, with the patients remaining on a liver transplant waiting list. We conclude that screening for extrahepatic manifestations of PCLD is mandatory, as certain lesions require treatment prior to liver transplantation. The lack of a genetic or familial association between these two cases show they are likely to have occurred by chance, rather than representing a previously unrecognized association between polycystic liver disease and cranial meningioma.

Socioeconomic and demographic profile of leprosy carriers attended in nursing consultations

A hanseníase é doença infecto-contagiosa para a qual, além das condições individuais, outros fatores relacionados aos níveis de endemia e às condições socioeconômicas desfavoráveis influem no risco de adoecer. Objetivou-se reconhecer o perfil socioeconômico e demográfico e o grau de incapacidade instalado dos portadores de hanseníase, atendidos no Centro de Saúde Escola de Botucatu, São Paulo, Brasil. Fizeram parte do estudo 37 pacientes. Os dados foram obtidos por meio do instrumento de consulta de enfermagem. Os resultados mostraram predominância de indivíduos com união estável (78%), brancos (92%), com idade entre 30 e 49 anos (51%), com baixo nível de escolaridade e com renda familiar per capita menor que um salário mínimo. Mais de um terço dos pacientes investigados (35%) apresentavam algum grau de incapacidade física. A associação do baixo perfil socioeconômico com a presença de incapacidades físicas imprime maior vulnerabilidade a essa população, podendo impactar negativamente a sua qualidade de vida.
