Papilomatosis esofágica: a propósito de un caso
Ponce Rodríguez,Félix M; Ponce Santoyo,Mabel; Román Castellani,Estela Vilma;
Revista M??dica Electr?3nica , 2011,
Abstract: the benign tumors of the esophagus are rare, being only the 0,5-0,8 % of all the esophageal tumors. around the 60 % of the benign esophageal tumors are leiomyomas, 20 % are cists and 5 % are polyps. the rest of the lesions occur with a frequency less than 2 % being curiosities, and among them there is the papilloma. the papilloma are benign, fibrous and sessile tumors covered by a squamous epithelium produced by the human papilloma virus (hpv), having the capacity of producing proliferative lesions in the skin and/or mucosa. in the digestive tract they are more frequently located to the proximal (mouth) and distal (rectum) endings. in the case we present, it is a distal esophageal location in a male patient aged 49, with symptoms suggesting a disease by gastro-esophageal reflux and/or disturbances of the esophageal motility, arriving to the diagnosis by endoscopy and biopsy: elevated esophageal lesions and the presence of koilocytes. we indicated a treatment with recombinant alpha 2 interferon, being pending the post-treatment endoscopic and histological evolution.
Papilomatosis esofágica: a propósito de un caso Esofagic Papilomatosis

Revista M??dica Electr?3nica , 2011,
Abstract: Los tumores benignos del esófago son raros, constituyendo solo el 0,5 al 0,8 % de todos los tumores esofágicos. Aproximadamente el 60 % de los tumores benignos del esófago son leiomiomas, el 20 % son quistes y el 5 % son pólipos. El resto de las lesiones ocurren con una frecuencia menor del 2 % y constituyen curiosidades y dentro de ellas tenemos al papiloma. Los papilomas son tumores benignos fibrosos y sésiles cubiertos por epitelio escamoso producidos por el papilomavirus humano (VPH), que tienen la capacidad de producir lesiones proliferativas en piel y/o mucosas. En el tubo digestivo se localizan más frecuentes hacia los extremos proximales (boca) y dístales (recto). El caso que se presentó se trata de una localización esofágica distal en un paciente de 49 a os de edad, masculino, con sintomatología sugestiva de una enfermedad por reflujo gastroesofágico y/o un trastorno de la motilidad esofágica, diagnosticándosele -por endoscopia y biopsia- lesiones elevadas esofágicas y la presencia de coilocitos. Se le indicó tratamiento con interferón alfa 2 recombinante, quedando pendiente de evolución endoscópica e histológica post-tratamiento.

Revista M??dica Electr?3nica , 2012,
Abstract: La Medicina Tradicional Natural ha entrado en una nueva etapa de desarrollo con el impresionante incremento de la demanda de alternativas terapéuticas. Una de sus limitaciones es la carencia de suficientes investigaciones, constituidas a partir de la aplicación de un método científico para la adquisición y la evaluación de los resultados obtenidos o el incorrecto dise o de estudio, sobre todo, en los que involucran la evaluación de agentes o procedimientos terapéuticos o diagnósticos, de medicina tradicional y natural, a través de ensayos clínicos. Con el objetivo de valorar la calidad del dise o metodológico de los ensayos clínicos en la medicina tradicional y natural, se realizó un estudio transversal de tipo descriptivo mediante el cual se valoraron los protocolos de ensayos clínicos de maestrantes y residentes de esta especialidad, de julio a noviembre de 2011. En total se analizaron 36 protocolos de ensayos clínicos. Los principales problemas detectados fueron: el 41,7 % por considerarse que el ensayo clínico no aportaría información relevante, el 80,5 % por aspectos del dise o, el 22,2 % por no existir una información clínica adecuada previa al inicio del ensayo que lo justifique, y el 16,7 % por no cumplir con los aspectos éticos inherentes a un ensayo clínico. ABSTRACT The Natural and Traditional Medicine has entered a new stage of development with the striking increase of the therapeutic alternatives demand. One of its limitations is the scarcity of researches, done applying the scientific method to acquire and evaluate the obtained results or the incorrect design of the research, mainly in those including the evaluation of agents, therapeutic procedures or diagnosis of Natural and Traditional Medicine, through clinical trials. With the objective of assessing the quality of the methodological design of the clinical trials of Natural and Traditional Medicine we carried out a cross-sectional, descriptive research to evaluate the clinical trials protocols of the Master′s defenders and residents of this specialty, from July to November 2011. We analyzed in total 36 protocols of clinical trials. The main problems detected were: 41,7 % of the trials did not add relevant information; 80,5 % had problems in the design; in 22,2 % of them there was a lack of previous clinical information justifying the beginning of the trial, and 16, 7 % did not fulfilled the ethical aspects of a clinical trial.

Abstract: Se evaluó el remodelamiento óseo en un grupo (GT) de mujeres premenopáusicas (n = 28) del sur argentino, clínicamente sanas, con densitometría normal de columna lumbar y cuello femoral, con predominio de baja ingesta de calcio habitual (ICa). La edad e índice de masa corporal fueron (promedio ± desviación estándar; mínimo-máximo): 33,2 ± 8,5 (22-49) a os; 23,0 ± 2,8 (19-30) Kg/m2, respectivamente. La mediana y rangos de ICa, calculados en base a encuesta alimentaria fueron: 568 (190-2.117) (mg/día). Con objeto de dilucidar el efecto de la suplementación cálcica, un subgrupo de 7 mujeres (GS), con ICa entre 429-664 mg/día, recibió 800 mg/día de calcio (citrato de calcio), bajo supervisión médica. Se determinaron inicialmente (To) en GT y a los 4 meses (Tf) en GS: crosslaps (CTX) y fosfatasa alcalina ósea (FAO), en suero; calcio (Ca), creatinina (Crea) y deoxipiridinolina (Dpir), en orina de 24 horas. Los resultados fueron: mediana (máximo-mínimo): a To, en GT y GS, respectivamente: Ca/crea (mg/mg): 0,110 (0,014-0,372); 0,089 (0,051-0,181); Dpir/crea (nM/mM): 5,2 (3,4-10,3); 5,2 (3,6-10,3); CTX (nM): 2,25 (0,30-6,20); 2,25 (1,49-5,20); FAO (UI/L): 58 (52-64); 58 (56-62). A Tf sólo CTX disminuyó significativamente: 1,16 (0,92-2,5) (p = 0,0175), indicando la capacidad de discernir cambios en el remodelamiento óseo y evidenciar los efectos benéficos de la suplementación. Bone markers were studied in 28 healthy premenopausal women (GT), living in Comodoro Rivadavia (Argentina), aged 33.2 ± 8.5 years (22-49), with normal femoral neck and lumbar spine (L2-L4) bone mineral density. Usual daily calcium intake (CaI), presented a median value and ranges of 568 (190-2.117) (mg/day). A subgroup of 7 women (GS) whith CaI lower than 700 mg/day received 800 mg/day of Ca (Ca citrate) during 4 months, under medical supervision. Fasting blood samples and 24 hs urine were collected at the beginning (To) in GT and after the supplementation period (Tf) in GS. Laboratory determinations were: calcium (Ca), creatinine (Crea) and deoxypiridinoline (Dpyr) (Pyrilinks, MetraBiosystems), in urine; crosslaps (CTX) (ELISA, Osteometer, BioTech) and bone alkaline phosphatase (BAPh) (after a selective precipitation with wheat-germ-lectine), in serum. The bone markers in GT and GS, at To, presented the following median values and ranges (between brackets), respectively: Ca/crea (mg/mg): 0.110 (0.014-0.372); 0.089 (0.051-0.181); Dpir/crea (nM/mM): 5.2 (3.4-10.3); 5.2 (3.6-10.3); CTX (nM): 2.25 (0.30-6.20); 2.25 (1.49-5.20); BAPh (UI/L): 58 (52-64); 58 (56-62). CTX was the only marker that a

Abstract: Increased heterosexual transmission of HIV among young women and their difficulties with safer sex communication calls for women-focused research. This qualitative phenomenological study explored the meaning and lived experiences of women, as part of larger pre-dissertation pilot on health protective sexual communication among young women in Gaborone, Botswana. This was a study conducted in two Gaborone City Council MCH clinics. Twenty women participated in individual in-depth interviews conducted in Setswana, tape-recorded, transcribed verbatim, translated into English for line by line analysis to extract themes and subthemes. Six main themes and nine subthemes emerged from the data. The main themes were: the meaning of HPSC, responsibility for HPSC, HPSC content, facilitating factors, partner’s response. Batswana women communicate with their male sexual partners about safer sex but face some difficulties. Further quantitative research can further explore women’s experiences with safer sex communication.
Thou shalt not get fat: Medical representations and self-images of obesity in a Mediterranean society  [PDF]

Health (Health) , 2013, DOI: 10.4236/health.2013.57159
Abstract:

This paper examines the link between lipophobia and representations and experiences of obesity in Catalonia (Spain) from two points of view: that of the physicians and other health professionals who diagnose and treat obesity as an illness, and that of their patients, especially those between adolescence and early adulthood. The qualitative data demonstrate that the increasing social rejection of fat people can be traced not only to moralizing discourses on “excessive” food consumption or the commodification of slenderness and health, but also to the recent definition of obesity as a disease. The medicalization of fatness, far from helping to destigmatize obesity, is becoming a way of resignifying it in moral terms. While doctors’ and patients’ perspectives diverge in some ways, they converge in others. In this text, I focus on the points of convergence arguing that biomedical understandings of obesity and overweight are characterized by a profound ambivalence. Young patients are regarded both as innocent victims of a permissive consumer society, and guilty of not following doctors’ orders. Although the family is held accountable for overweight or obesity in children, as young people become more independent, guilt is individualized and environmental causes are limited to inappropriate diet and insufficient exercise. Most narratives of young people with weight problems reflect similar ideas about the causes and the responsibility for obesity. Their acceptance of the basic premise that deviating from weight standards and rules for healthy eating are voluntary actions leads them to lose faith in themselves. The stigmatization of obesity thus becomes a vicious circle: the obese acceptance—even consider normal—the incriminations leveled at them, and blame themselves for their situation and their inability to prevent it.

Abstract:

The difficulties in communication about sexuality-related matters in HIV prevention require appropriate research approaches. Scenarios can be useful in qualitative, quantitative research methods and interventions related to sensitive cognitive issues of human sexuality. This paper presents an analysis of the use of scenarios in HIV/AIDS prevention research from the literature and empirical evidence. Examples of scenario-based instrument development research studies in safer sex communication for the prevention of HIV/AID by Kalichman (2000) and Magowe (2006) are provided. A computer-based search of articles addressing the use of case scenarios in research was conducted on Google and Google scholar, using the following search terms: “case scenarios”, “scenarios in research”, case scenarios in safer sex negotiation: “case scenarios in safer sex communication”, “case scenarios in dyadic communication”, “partner communication”, “case research”, “vignettes in HIV/AIDS research”, and, “sexuality related vignettes”. Papers included provided the definition, purpose, components, types of scenarios, use of scenarios in safer sex communication. Examples are drawn from instruments development studies using with case scenarios. Twenty-nine documents were retrieved, and eight of these studies addressed the use of scenarios in research. Five studies were specifically on HIV prevention research, focusing on safer sex communication, negotiation or couple/partner communication. The content of the studies included the definition of scenarios, case scenarios and vignettes; purpose and use of scenarios in research. Studies showed that scenarios are useful in qualitative elicitation of themes and content for instrument development for further quantitative research. Nursing deals with sensitive and complex cognitive issues in human behavior, and therefore scenario-based research can help develop personoriented research and interventions while protecting the individual’s privacy and confidentiality.
