Resumo Objetivo Avaliar fatores preditivos de morte em pacientes de idade igual ou superior a 70 anos com fratura proximal do fêmur submetidos a tratamento cirúrgico. Métodos Análise de prontuários médicos criando-se uma coorte retrospectiva com seguimento de 6meses. Foramanalisados 124 prontuários após aplicação dos critérios de inclusão e exclusão. Todos os pacientes foram tratados por um único cirurgião ortopédico em condições de uniformidade. Resultados Taxa de mortalidade de 34.7%, sendo o perfil mais comum de paciente o indivíduo do gênero feminino, com 85 anos e ao menos 1 comorbidade. Os pacientes com idade superior a 85 anos, internação hospitalar por mais de 7 dias, ao menos 1 comorbidade presente e internação em centro de terapia intensiva (CTI) apresentaram maior risco de óbito (respectivamente 2; 2,5; 4 e 4 vezes maior). Conclusão Em relação ao desfecho óbito, apesar de não encontramos diferença estatisticamente significativa no que se refere à topografia da lesão e como essas se comportamnomomento em que coexistemjunto a internação em CTI, acreditamos na necessidade de maiores investigações sob essa ótica na população com o perfil estudado.

Abstract Objective To evaluate predictive factors of death in patients aged ≥ 70 years old with proximal femoral fracture (PFF) submitted to surgical treatment. Methods An analysis of medical records by creating a retrospective cohort with a 6- month follow-up. A total of 124 charts were analyzed after applying the inclusion and exclusion criteria. All of the patients were treated by a single orthopedic surgeon under uniform conditions. Results The mortality rate was of 34.7%, and the most common profile was female, 85 years old, and with at least 1 comorbidity. Patients > 85 years old, hospitalized for > 7 days, with at least 1 comorbidity, and staying at the intensive care unit (ICU) had a higher risk of death (2, 2.5, 4, and 4 times higher, respectively). Conclusion Regarding the death outcome, although we did not find a statistically significant difference in the topography of the lesion and in its behavior in its coexistence with ICU hospitalization, we believe that further investigations under this perspective are required in a population with the studied profile.

ABSTRACT Coccidioidomycosis is a fungal infection caused by Coccidioides immitis or Coccidioides posadasii. These fungi are known to thrive in desert climate. Fungi produce infectious arthroconidia in soil, they are aerosolized in the air and when inhaled by humans, usually cause infections such as pneumonia. The first cases of coccidioidomycosis in Brazil were reported in 1978. Since then, there have been other reports mainly from desert regions of Northeastern Brazil. The present report describes three cases of coccidioidomycosis on male farmers from Serra Talhada county, Pernambuco State, who developed pneumonia and were subsequently diagnosed with pulmonary coccidioidomycosis. These three farmers were successfully treated with oral fluconazole. They reported having hunted armadillos in a rural and arid area of Pernambuco State. Armadillos are known to be carriers of Coccidioides. This is the first report of infection caused by Coccidioides in Pernambuco State, Brazil.

OBJETIVO: Avaliar a acurácia da espessura endometrial ecográfica e características histeroscópicas em predizer malignidade em mulheres na pós-menopausa submetidas à ressecção cirúrgica de pólipos endometriais. MÉTODOS: Quinhentos e vinte e uma (521) mulheres na pós-menopausa submetidas à ressecção histeroscópica de pólipo endometrial entre janeiro de 1998 e dezembro de 2008 foram incluídas no estudo. Para cada valor de espessura endometrial ecográfica e tamanho dos pólipos na histeroscopia, a sensibilidade, a especificidade, valor preditivo positivo (VPP) e valor preditivo negativo (VPN) foram calculados em relação ao diagnóstico histológico de malignidade. Os melhores valores de sensibilidade e especificidade para o diagnóstico de malignidade foram determinados pela curva Receiver Operating Characteristic (ROC). RESULTADOS: O diagnóstico histológico identificou a presença de pré-malignidade ou malignidade em 4,1% dos casos. A espessura endometrial medida por ultrassonografia em casos de pólipos malignos foi maior quando comparado com pólipos benignos e pré-malignos. Na histeroscopia os pólipos malignos também foram maiores. A espessura endometrial de 13 mm mostrou uma sensibilidade de 69,6%, especificidade de 68,5%, VPP de 9,3% e VPN de 98% para predizer malignidade em pólipo endometrial. A medida do pólipo por histeroscopia mostrou que para pólipos de 30 mm de tamanho, a sensibilidade foi de 47,8%, a especificidade foi de 66,1%, VPP foi de 6,1% e VPN foi de 96,5% para predizer o câncer. CONCLUSÕES: A espessura endometrial ultrassonográfica mostrou uma maior acurácia que a avaliação histeroscópica do tamanho do pólipo para predizer malignidade nessas lesões endometriais. Apesar disso, ambas as técnicas não mostraram boa acurácia para excluir a necessidade de fazer a avaliação histológica dos casos suspeitos.

PURPOSE: To evaluate the accuracy of sonographic endometrial thickness and hysteroscopic characteristics in predicting malignancy in postmenopausal women undergoing surgical resection of endometrial polyps. METHODS: Five hundred twenty-one (521) postmenopausal women undergoing hysteroscopic resection of endometrial polyps between January 1998 and December 2008 were studied. For each value of sonographic endometrial thickness and polyp size on hysteroscopy, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated in relation to the histologic diagnosis of malignancy. The best values of sensitivity and specificity for the diagnosis of malignancy were determined by the Receiver Operating Characteristic (ROC) curve. RESULTS: Histologic diagnosis identified the presence of premalignancy or malignancy in 4.1% of cases. Sonographic measurement revealed a greater endometrial thickness in cases of malignant polyps when compared to benign and premalignant polyps. On surgical hysteroscopy, malignant endometrial polyps were also larger. An endometrial thickness of 13 mm showed a sensitivity of 69.6%, specificity of 68.5%, PPV of 9.3%, and NPV of 98% in predicting malignancy in endometrial polyps. Polyp measurement by hysteroscopy showed that for polyps 30 mm in size, the sensitivity was 47.8%, specificity was 66.1%, PPV was 6.1%, and NPV was 96.5% for predicting cancer. CONCLUSIONS: Sonographic endometrial thickness showed a higher level of accuracy than hysteroscopic measurement in predicting malignancy in endometrial polyps. Despite this, both techniques showed low accuracy for predicting malignancy in endometrial polyps in postmenopausal women. In suspected cases, histologic evaluation is necessary to exclude malignancy.

OBJECTIVE: The present study evaluated the association between lactotransferrin (LTF) gene polymorphism (exon 2, A/G, Lys/Arg) and dental caries. MATERIAL AND METHODS: A convenience sample of 110 individuals, 12 years old, was divided into: group 1, 48 individuals without caries experience (DMFT=0), and group 2, 62 subjects with caries experience (DMFT>1). DNA was obtained from a mouthwash with 3% glucose solution, followed by a scrapping of the oral mucosa. After DNA purification, polymerase chain reaction (PCR), single strand conformation polymorphism (SSCP) was performed to access the study polymorphism. The LTF A/G (Lys/Arg) polymorphism had been previously reported as located in exon 1. RESULTS: Allele 1 of the study polymorphism was associated with low DMFT index and showed a protective effect against caries experience (OR=0.16, IC=0.03-0.76, p=0.01). CONCLUSIONS: Lactotransferrin A/G (exon 2, Lys/Arg) polymorphism was associated with susceptibility to dental caries in 12-year-old students.

Neste experimento, observou-se o comportamento de porta-enxertos mono e poliembriônicos de manga em relação a baixa temperaturas, na Estação Experimental de Agronomia de Tatuí, do IAC. Utilizaram-se como porta-enxertos monoembriônicos as variedades Sensation, Haden e Tommy Atkins para a copa Haden, e os poliembriônicos Coquinho, Manga-d'Água, Carabao e Pico para as copas Haden e IAC 100 Bourbon. As mudas, com 18 a 24 meses de idade, foram plantadas em janeiro de 1990. As temperaturas registradas no abrigo meteorológico atingiram valores de 1ºC, 2ºC e 2,4ºC, respectivamente, nos dias 19, 20 e 23 de maio de 1990; 1,6ºC, 1ºC e 2ºC, nos dias 22, 23 e 24 de junho e 1ºC e 2,4ºC, nos dias 30 e 31 de julho, respectivamente. Essas temperaturas, no abrigo meteorológico, correspondem a temperaturas inferiores a 0ºC ao nível do solo. Verificou-se que não houve morte do porta-enxerto Carabao, independentemente da copa enxertada. Para os demais porta-enxertos, o índice de mortalidade variou de 35 a 70%.

The performance of mango mono and poliembrionic rootstock to environmental low temperature was observed at Tatuí, SP, Brazil (23º20'S and 47º52'W). The varieties Sensation, Haden and Tommy Atkins were used as monoembrionic rootstock for Haden scion and Coquinho, Manga d'Àgua, Carabao and Pico as poliembrionic rootstock for Haden and IAC 100 Bourbon scions. The grafted plants aging 18 to 24 months were planted in January, 1990. Registered temperatures in the standard weather station reached 1ºC, 2ºC and 2,4ºC in May 19th, 20th and 23rd, 1990 respectively; 1,6ºC, 1ºC and 2ºC in June, 22nd, 23rd and 24th and 1ºC and 2,4ºC in July, 30th and 31st respectively. These temperatures at the weather station are corresponding to temperetures under 0ºC at soil level. The rootstock Carabao survived to those temperatures in spite of the scion. The others rootstocks showed a mortality from 35 to 70%
