Estudio clínico evolutivo de la Leucoplasia oral en 412 pacientes
2019
Introducción: La leucoplasia oral (LO) es la lesión potencialmente maligna más frecuente de la mucosa oral, es considerada clínicamente como una lesión predominantemente blanca que no se desprende al raspado y que no puede catalogarse como ninguna otra lesión definida, y que presenta un elevado riesgo de desarrollar cáncer oral. Se estima una prevalencia mundial de la del 2%, con una transformación maligna del 1%. Objetivos: los objetivos fueron realizar un estudio clínico de la sintomatología, localización y aspectos clínicos de la leucoplasia oral, catalogar y clasificar a los pacientes de leucoplasia oral en el sistema de estadiaje de van der Waal (2013), ver si existía asociación entre …
Diagnosis of focal nodular hyperplasia. Role of imaging techniques.
2002
Focal nodular hyperplasia (FNH) is a rare benign liver lesion which is difficult to differentiate from other benign liver pathologies and hepatocellular carcinoma. However, with appropriate new imaging techniques it is, at present, possible to diagnose this lesion with certainty thus avoiding invasive tests. Patient follow-up is also facilitated. It is often incidentally discovered during an abdominal ultrasound for other pathologies. Color power Doppler allows, in most cases, one to distinguish it from other focal liver lesions. However, in doubtful cases contrast-enhanced computed tomography and magnetic resonance imaging can help us to define the exact nature of the lesion. It is only oc…
Lēmuma koku, gadījuma mežu un loģistiskās regresijas modeļu salīdzinājums klientu maksātspējas prognozēšanai
2017
Mūsdienu tehnoloģiju attīstība nodrošina iespēju jebkurā laikā un vietā saņemt naudas aizdevumu. Tas savukārt nozīmē, ka uzņēmumiem, kas izsniedz aizdevumus, ir jānodrošina ātra pieteikumu izvērtēšana un procesam jābūt maksimāli automatizētam. Balstoties uz vēsturiskiem datiem, var veidot modeļus, kas prognozēs jauno klientu maksātspēju. Mērķa pazīme pieņem tikai divas vērtības: ’labs’ vai ’slikts’. Tā ir divu klašu klasifikācijas problēma. Darbā tiek apskatītas trīs metodes, kā risināt šo problēmu, - lēmumu koku algoritms, gadījuma mežu algoritmsunloģistiskāregresija.

Autosomal recessive severe dwarfism in a Sicilian girl: a new form of osteodysplastic primordial dwarfism?
1996
A new type of osteodysplastic primordial dwarfism is delineated in a 5- year-old female child with severe growth retardation of prenatal onset, gross skeletal changes, a non-Seckel facial phenotype, and presumed autosomal recessive inheritance.
Variación de tamaño de la hiperplasia nodular focal mediante resonancia magnética

Objective: To evaluate the changes in the size of focal nodular hyperplasia (FNH) during longterm magnetic resonance imaging (MRI) follow-up.
Analysis of type-restricted and cross-reactive epitopes on virus-like particles of human papillomavirus type 33 and in infected tissues using monoclo…
1994
A panel of six monoclonal antibodies recognizing at least three different antigenic regions has been raised against the L1 major capsid protein of human papillo-mavirus type 33 (HPV-33), which is associated with cervical carcinoma. The antigenic sites defined by these antibodies have been mapped and classified as type-restricted or broadly cross-reactive using bacterially expressed L1 fusion proteins of a variety of HPV types. Conformational and linear epitopes have been distinguished using native and denatured virus-like particles. HPV infection of genital lesions has been analysed using both monoclonal antibodies and DNA amplification by PCR. The antibodies obtained should be useful to pr…
Conformational and linear epitopes on virus-like particles of human papillomavirus type 33 identified by monoclonal antibodies to the minor capsid pr…
1995
The organization of epitopes on the minor capsid protein L2 of human papillomavirus (HPV) type 33 has been analysed using three monoclonal antibodies (MAbs) generated against a large fragment of the L2 protein (amino acids 82-259) expressed as a glutathione S-transferase fusion protein. The topology of the L2 epitopes has been investigated with respect to the structure of HPV-33 virus-like particles (VLPs). Two of the MAbs reacted with linear epitopes which were mapped to amino acids 153-160 and 163-170, respectively. These epitopes were accessible in denatured but not in native VLPs consisting of L1 and L2, suggesting an internal location. The third antibody was unable to detect denatured …
The Association of Basal Insulin Glargine and/or n-3 Fatty Acids With Incident Cancers in Patients With Dysglycemia
2014
OBJECTIVE Epidemiologic studies linking insulin glargine and glucose-lowering therapies to cancers and n-3 fatty acids to cancer prevention have not been confirmed. We aimed to assess the effect of insulin glargine and n-3 fatty acids on incident cancers within the context of the ORIGIN (Outcome Reduction with Initial Glargine Intervention) trial. RESEARCH DESIGN AND METHODS The ORIGIN trial is an international, long-term, randomized two-by-two factorial study comparing insulin glargine with standard care and n-3 fatty acids with placebo (double blind) in people with dysglycemia at high risk for cardiovascular events. The primary outcome measure (cancer substudy) was the occurrence of any …
Cardiorenal syndrome followed by acute hepatitis C in a patient with acute myeloid leukemia
1969
SUMMARY Cardiorenal syndrome involves altering cardiac and renal function. These patients frequently develop resistance to diuretic therapy, so that ultrafiltration should be applied in emergency for saving them. Concomitant presence of an active hematologic malignancy represents an important complicating factor. We present the case of an elderly patient with acute myeloid leukemia, appeared on the background of myelodysplastic syndrome who, during marrow aplasia occurred after the first course of induction chemotherapy, developed a cardiorenal syndrome, which required repeated sessions of hemodialysis. Complete hematologic remission and efficiency of fluid depletion therapy allowed the sec…
