Abstract: La colocación de implantes dentales osteointegrados y la retención de las prótesis estomatológicas convencionales de acrílico es un grave problema en pacientes con reborde alveolar atrófico. La distracción osteogénica ofrece en la actualidad una solución potencial ante la severa pérdida de tejido óseo alveolar. Este estudio tuvo el propósito de evaluar en nuestro medio la Efectividad y Estabilidad de la osteogénesis alveolar. Se realizó un ensayo clínico Fase II. Fueron tratados 5 pacientes con atrofia del reborde alveolar mandibular o maxilar con distractores alveolares intraorales producidos por Walter Lorenz Surgical, Inc, (ROTT-NELSON-1713-06-04) para inducir osteogénesis. Los pacientes fueron atendidos de forma ambulatoria. El período de latencia fue de 5 días, la tasa de distracción de 1mm diario y el período de contención de 4 semanas . La efectividad de la distracción aplicada fue 76.3% y la estabilidad de 92.0 %. La media de la distracción total obtenida fue 7,25 mm. La Distracción osteogénica resultó ser un método eficaz para lograr incremento de la cresta alveolar en pacientes que presentaron atrofias previas.

María Elena Acevedo,Marco Antonio Acevedo,Federico Felipe
Mathematical Problems in Engineering , 2009, DOI: 10.1155/2009/680212
Abstract: Bidirectional Associative Memories (BAMs) based on first model proposed by Kosko do not have perfect recall of training set, and their algorithm must iterate until it reaches a stable state. In this work, we use the model of Alpha-Beta BAM to classify automatically cancer recurrence in female patients with a previous breast cancer surgery. Alpha-Beta BAM presents perfect recall of all the training patterns and it has a one-shot algorithm; these advantages make to Alpha-Beta BAM a suitable tool for classification. We use data from Haberman database, and leave-one-out algorithm was applied to analyze the performance of our model as classifier. We obtain a percentage of classification of 99.98%.

David Sáez Martínez, Felipe López Oliva, María Jesús Fernández Ace?ero, Elena Fontoira Moyer, Juan Luis Arranz Cozar
International Journal of Clinical Medicine (IJCM) , 2013, DOI: 10.4236/ijcm.2013.412A1001
Abstract:

Background: IgG4-related disease is a systemic lymphoproliferative syndrome that shows IgG4-producing plasma cell expansion in affected organs with fibrotic or sclerotic changes. The lacrimal glands, salivary glands and pancreas are typically affected. We report a case of IgG4-related disease presenting a soft tissue tumor affecting skeletal muscle. Case Report: A 32-year-old man presented a soft tissue mass in his left arm. Magnetic resonance imaging revealed a spindle like, peripheral mass, in the lateral head of the triceps of his left arm. Tru-Cut Biopsy provided the diagnosis of IgG4-related disease affecting skeletal muscle. Glucocorticoid treatment was effective. Conclusion: To our knowledge, this is the first reported case of IgG4-related disease affecting skeletal muscle and presenting a soft tissue mass.

Statins Inhibit the Proliferation and Induce Cell Death of Human Papilloma Virus Positive and Negative Cervical Cancer Cells

International Journal of Biomedical Science , 2009,
Abstract: Statins, competitive inhibitors of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, have anti-tumoral effects on multiple cancer types; however, little is known about their effect on cervical cancer. We evaluated the effect on proliferation, cell cycle, oxidative stress and cell death of three statins on CaSki, HeLa (HPV+) and ViBo (HPV-) cervical cancer cell lines. Cell proliferation was assayed by crystal violet staining, cell cycle by flow cytometry and cell death by annexin-V staining. Reactive oxygen species (ROS) production was evaluated by the oxidation of 2,7-dichlorofluorescein diacetate and nitrite concentration (an indirect measure of nitric oxide (NO) production), by the Griess reaction. Inhibition of cell proliferation by atorvastatin, fluvastatin and simvastatin was dose-dependent. ViBo cells were the most responsive. Statins did not affect the cell cycle, instead they induced cell death. The antiproliferative effect in ViBo cells was completely inhibited with mevalonate, farnesyl pyrophosphate (FPP) and geranylgeranyl pyrophosphate (GGPP) treatments. In contrast, cell proliferation of CaSki and HeLa cells was partially (33%) rescued with these intermediates. The three statins increased ROS and nitrite production, mainly in the ViBo cell line. These results suggest that statins exert anti-tumoral effects on cervical cancer through inhibition of cell proliferation and induction of cell death and oxidative stress. Statins could be an aid in the treatment of cervical cancer, especially in HPV- tumors.

Revista Chilena de Obstetricia y Ginecología , 2012,
Abstract: Antecedentes: En pacientes con cáncer de endometrio se discute la concordancia entre biopsia pre e intraoperatoria versus la definitiva, en grado de diferenciación, tipo histológico y profundidad de mioinvasión. Método: Se determinó sensibilidad (S), especificidad (E), valor predictivo positivo (VPP) y valor predictivo negativo (VPN) de: grado de diferenciación bien diferenciado y tipo histológico sólo endometrioide en biopsia preoperatoria; y grado de diferenciación bien diferenciado, tipo histológico sólo endometrioide y profundidad de mioinvasión menor o igual a la mitad interna del miometrio, en biopsia intraoperatoria, para resultados similares en biopsia definitiva en serie clínica de pacientes con cáncer de endometrio clínicamente limitado al útero sometidas a tratamiento quirúrgico primario. Resultados: Biopsia preoperatoria: grado de diferenciación bien diferenciado S: 100%, E: 77,8%, VPP: 78,9% y VPN: 100%. Tipo histológico sólo endometrioide S: 86,4%, E: 33,3%, VPP: 86,4% y VPN: 33,3%, para resultado similar en biopsia definitiva. Biopsia intrao-peratoria: grado de diferenciación bien diferenciado S: 91,7%, E: 94,4%, VPP: 91,7% y VPN: 100%. Tipo histológico sólo endometrioide S: 95,7%, E: 77,8%, VPP: 95,7% y VPN: 70%. Profundidad de mioinvasión menor o igual a mitad interna del miometrio S: 95,2%, E: 30%, VPP: 74,1% y VPN: 75%, para resultado similar en la biopsia definitiva. Conclusión: No hubo concordancia absoluta de grado de diferenciación bien diferenciado entre biopsia preoperatoria y biopsia definitiva, ni de grado de diferenciación bien diferenciado ni tipo histológico sólo endometrioide entre biopsia intraoperatoria y biopsia definitiva, por lo que se recomienda etapificación quirúgica independiente de los resultados de las biopsias pre e intra operatoria. Background: Among patients with endometrial cancer there is discussion about concordance between pre and intraoperatory biopsy and the definitive one, for diferentiation grade, histologyc type and depth of myoinvasion. Method: To determinate sensibility (S), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of: good diferenciated diferentiation grade and only endometrioid histologyc type on preoperatory biopsy, and good diferenciated diferentiation grade, only endometrioid histologyc type and inner half of the miometryum or less myoinvasion depth on intraoperatory biopsy, for similar result on definitive biopsy in a clinical cohort of patients with endometrial cancer clinically limited to uterus treated with primary surgery. Results: Preoperatory
