RESUMO

Resumen (analítico) El artículo analiza las implicaciones de la guerra en la configuración del ser joven rural en Colombia en La Merced (Caldas) y Vista Hermosa (Meta). Es una investigación cualitativa con enfoque narrativo, que indaga en las experiencias de tres sobrevivientes de la violencia entre los años 1995 y 2005, por medio de marcadores de juventud. De los resultados se desprende que la guerra trazó cursos de vida a los jóvenes rurales, como ser cultivadores de hoja de coca e integrantes de grupos armados, marcándose transiciones en las que se restringieron las capacidades para agenciar posibilidades de futuro fuera de los marcos de la guerra, pero también cursos de vida en resistencia vinculados a la acción colectiva con otros jóvenes.


Abstract (analytical) This article analyzes the implications of war in the configuration of rural youth in Colombia in La Merced, Caldas and Vista Hermosa, Meta. It describes qualitative research that uses a narrative approach to analyze the experiences of three survivors of violence between 1995 and 2005 through the telling of significant events that occurred during their youth. The results show that the war established specific life courses for rural youth, such as growing coca leaf and being a member of armed groups. These transitions demonstrate how their capacity to pursue possible life paths outside the frame-work of war were restricted, but also highlight life paths involving resistance to the war that were linked to collective action with other young people.


Resumo (analítico) O artigo analisa as implicações da guerra na configuração da juventude em zonas rurais da Colômbia, em La Merced, Caldas e Vista Hermosa, Meta. É uma pesquisa qualitativa com abordagem narrativa a partir da qual são analisadas as vivências de três sobreviventes de violência entre 1995 e 2005, por meio dos marcadores juvenis. Os resultados mostram que a guerra traçou rumos de vida para a juventude rural, como ser cultivadores de folha de coca e membros de grupos armados, marcando transições em que se restringiam as capacidades de encontrar possibilidades de futuro fora dos marcos da guerra, mas também, cursos de vida em resistência vinculados à ação coletiva com outros jovens.

RESUMO

RESUMEN Objetivo Analizar el comportamiento de la malaria en relación con la economía de la coca en la región del Guaviare, Colombia entre 1978 y 1989. Métodos Revisión documental retrospectiva, a través del análisis de archivos históricos, entrevistas y fuentes secundarias. Resultados Se identificaron dos periodos de crisis de la bonanza coquera o cocalera durante el tiempo de estudio, con fluctuaciones en el número de habitantes. Al analizar la relación entre las variaciones del precio de la cocaína y los casos de malaria, se encontró que hay un incremento de casos en épocas de crisis. Conclusiones El aumento de casos de malaria en la región posiblemente se deba a que las personas que estaban en las zonas rurales se desplazaron a las cabeceras urbanas, motivadas por la baja producción de la pasta de coca. Esto incrementó la concentración de población susceptible y, por tanto, el aumento de casos, o probablemente existió un aumento en el registro de la enfermedad.(AU)


ABSTRACT Objective To analyze the relationship between malaria and coca economy in the region of Guaviare, Colombia between 1978 and 1989. Materials and Methods Retrospective documentary analysis using historical archives, interviews and secondary sources. Results Two critical periods for the coca bonanza, with population fluctuations, were identified between 1978 and 1989. After analyzing the relationship between variations in the price of cocaine and positive cases of malaria, an increase in cases was identified during those crises. Conclusions The increase of malaria cases in the region is possibly associated to the migration of people from rural areas to urban centers, motivated by the low production of coca paste. This increased the concentration of susceptible population and, therefore, the number of cases; however, it is possible that the report of these cases experienced an upsurge.(AU)

RESUMO

OBJECTIVES: We examined the effect of commercial plum beverages on dental erosion and whether the addition of calcium to these beverages would inhibit dental erosion. METHODS: We analyzed three groups as follows: Maesil 1 group (Chorok Maesil), Maesil 2 group (Sunkist plum), both of which were selected from commercially-available plum beverages, and Calcium-added maesil group (addition of 3% calcium to Chorok Maesil). For negative and positive control groups, Jeju Samdasoo and Coca Cola were selected, respectively. The characteristics of the experimental beverages were analyzed, and the specimens were immersed in the experimental beverage. The degree of erosion was measured by Vickers hardness number (VHN) and scanning electron microscope images. RESULTS: Positive control group had the lowest pH (2.50±0.03), followed by Maesil 2 (pH 2.59±0.01), Maesil 1 (pH 2.81±0.02), calcium-added maesil (pH 4.19±0.01), and negative control group (pH 7.57±0.06). Significant differences were found in surface microhardness between positive control, Maesil 1, Maesil 2 and calcium-added maesil group before immersion and at 30 minutes after immersion (P<0.05), and change in VHN (positive control group, −80.94±20.63; Maesil 1 group, −69.33±24.88; and Maesil 2 group, −78.49±18.60 in comparison with negative control group, −6.57±26.73). There was no significant difference (P<0.05) in change in VHN between calcium-added maesil (−13.02±17.33) and negative control group. CONCLUSIONS: Plum beverages can potentially induce dental erosion due to their low pH. However, adding calcium to these beverages can reduce the risk of dental erosion. Therefore, the risk of dental erosion must be considered during consumption of plum beverages, and the addition of calcium into plum beverages may be considered as a way to prevent dental erosion.

RESUMO

Desde la medicina oficial se desconoce y subestima el uso de otras formas de atención, por lo que este trabajo tiene como objetivos caracterizar el conocimiento sobre uso de hierbas medicinales en la zona sudeste de la ciudad de Salta; identificar cuáles se utilizan para tratar problemas de salud; y valorar su frecuencia de uso. Se realizó una investigación cuali-cuantitativa, entrevistando a informantes claves y grupos focales. Se confeccionaron listas de hierbas medicinales, y sus usos se categorizaron por problemas de salud. Se realizó una encuesta sobre frecuencia de usos medicinales. Se mencionaron 59 hierbas medicinales con una media de 2,3 usos por planta. Con un "Nivel de importancia Significativo" se encuentran quimpe, tusca, paico, coca, molle, ruda y hediondilla. El "coqueo" se encontró en 54% de las familias. El 52% utiliza alguna hierba para afecciones gastrointestinales, el 45% para problemas de la piel, el 40 % para afecciones respiratorias, el 33% para "empacho" y 17% para problemas renales, sin diferencias significativas en los usos por grupo etáreo. La población tiene amplio conocimiento sobre hierbas medicinales. La medicina formal debe legitimar estos conocimientos e incluirlos en su práctica.


Traditional health professionals underestimate and fail to recognize the use of other forms of health care, therefore this research has the objective of characterizing knowledge about the use of medicinal herbs in the southeastern area of Salta city; to identify which herbs are used to treat health problems; and to assess its frequency of use. Qualitative and quantitative research was conducted by interviewing key informants and focus groups. Lists of medicinal herbs and uses were created and categorized by health problems. Finally, a closed survey on frequency of use was carried out. Fifty-nine herbs were mentioned with an average of 2.3 uses per plant. quimpe, tusca , paico, coca, molle, ruda and hediondillawere herbs marked as “with a Significant Level of Impotanse”. The use of coca was found in 54% of the families interviewed. Fifty-two percent used some herb for gastrointestinal disorders, 45% for skin problems, 40% for respiratory conditions, 33% for indigestion and 17% for kidney problems, with no significant differences in uses according toage groups. Population has a good knowledge of medicinal herbs. Formal medicine should legitimize this knowledge and include it in its practice.

RESUMO

En el Perú existe una elevada prevalencia de trastornos por consumo de estimulantes y aunque no existen estadísticas precisas, puede asumir se la ocurrencia de múltiples casos de psicosis inducida por el consumo declorhidrato de cocaína o pasta básica de cocaína. Por otro lado, la masticación de hojas de coca constituye partedel acervo cultural e histórico de un gran segmento de la población peruana. A propósito de un caso de confusión diagnóstica (un cuadro de esquizofrenia en un paciente masticador de hojas de coca diagnosticado erróneamente como psicosis inducida por cocaína, en base a la positividad de un examen de metabolitos urinarios de dichasustancia) revisamos razonablemente la bibliografía correspondiente al cuadro clínico de psicosis inducida por consumo de cocaína, su diagnóstico diferencial con otras psicosis, y las características de las pruebas de laboratorio para la detección de cocaína y sus derivados. Concluimos recomendando un mayor conocimiento e información respecto a los fenómenos asociados al consumo de la hoja de coca y de la cocaína, por parte del personal de salud, a fin de prevenir confusiones diagnósticas como la del caso aquí reportado.


In Peru, there is a high prevalence of stimulant use disorders and thus, although no accurate statistics are available, multiple cases of psychoses induced by cocaine hydrochloride and cocaine paste intake may occur. Moreover, chewing of dry coca leaves is part of the cultural and historical heritage of a large segment of the Peruvian population. On the basis of a case of psychiatric misdiagnosis (a primary schizophrenic psychosis in a chewer of coca leaves, misdiagnosed as cocaine-induced psychosis based on an positive test of urinary cocaine metabolites), we review pertinent literature on the clinical presentation of cocaine-induced psychosis and its differential diagnosis with other psychoses, and the characteristics of the laboratory tests used for the detection of cocaine and its metabolites. As a conclusion, the suggestion is made that health and mental health workers should have more information and knowledge about the phenomena associated with the consumption of coca leaves and cocaine, in order to avoid misdiagnosis similar to the reported case.

RESUMO

OBJECTIVES: This study was conducted to investigate the influence of several commercial red ginseng beverages on the surface of healthy teeth and to confirm the anti-erosive effect of added calcium. METHODS: For the experimental group selection, the pH of red ginseng beverages on the market were measured and the mean pH was calculated. Beverages with the lowest pH (Dong Wha Hongsam Gold; red ginseng beverage group with pH 2.98), mid-level pH (Kwangdong Jin Hongsam Gold; red ginseng beverage group with pH 3.61), and the highest pH (Hongsam Han Ppuri; red ginseng beverage group with pH 5.34) were selected as the experimental groups. In order to confirm the anti-erosive effect of added calcium, we added 1% calcium to the product with the lowest pH (red ginseng beverage group with pH 2.98+1% Ca) and included the product in the experimental group. Jeju Samdasoo and Coca Cola were used as the negative and positive control groups, respectively. We soaked healthy bovine teeth samples in the selected six beverages for 1, 3, 5, 10, 15, and 30 minutes. The surface microhardness (VHN, Vickers hardness number) and the surface roughness (center line average roughness, Ra) of each sample were measured, and the surface features were observed with a scanning electron microscope (SEM). RESULTS: The change in the surface micro-hardness (△VHN) of teeth after 30 minutes of soaking in each beverage was the highest in the positive control group (60.99±8.99), followed by A (41.63±8.96), B (30.64±8.21), and the negative control group (―4.48±7.29) (P<0.05). No significant difference was observed in group C (―18.79±10.11) or D (―16.40±7.89). Surface roughness (Ra) exhibited significant differences between each group (P<0.05). Surface roughness (Ra) was high in A (102.88±26.34) and B (67.76±39.89), as well as in the positive control group (101.21±39.59). In contrast, C (30.80±28.49) and D (25.05±10.79) showed low surface roughness values similar to the negative control group (23.77±22.48). Following SEM examination, severe cracks were observed between the crystals in groups A and B; such characteristics were similar to those of the positive control group. CONCLUSIONS: Red ginseng beverages with low pH were shown to erode the surface of the teeth. When calcium was added to the red ginseng beverages, a decrease in tooth erosion was observed. Therefore, the possibility of tooth erosion should be considered when drinking red ginseng beverages. Furthermore, the addition of calcium to red ginseng beverages can be an alternative solution to suppress tooth erosion.

RESUMO

Considerando la veracidad de los beneficios de la hoja de coca y su comercio como un alimento listo para el consumo humano; este estudio tiene por objetivo determinar la concentración de Bacterias aerobias mesófilas (BAM) y hongos, e identificar parásitos así como hongos en la hoja de coca seca yungueña y chapareña, mediante un estudio descriptivo de corte transversal. Se estudiaron 74 muestras de hoja de coca chapareña y yungueña, se cuantificaron las BAM/g cultivadas en agar deTripticasa de soya, se cuantificó e identificaron los hongos luego del cultivo en agar Sabouraud y se observaron parásitos por microscopía. Se obtuvo una concentración de 3.36*10(7) en la hoja Yungueña: en comparación a 7.33*10(7) UFC/g en la chapareña: ambos fuera del rango permitido según IBNORCA; el nivel de hongos en la Yungueña fue: 1 937 287 UFC/g y en la chapareña: 1 955 255 UFC/g, valores encima de lo permitido según el Reglamento Sanitario de los alimentos de la Norma Chilena, se identificaron: Aspergillus Terreus,Aspergillus Fumigatus, Aspergillus Niger,Aspergillus nidulans, Mucor s.p., Rizhopus s.p., Fusarium s.p. (Solo en la muestra chapareña), Aspergillus Fumigatus, Aspergillus Niger, Fusarium oxysporum, Penicillium citreovirens, Penicillium spinulosum, Penicillium s.p., y levaduras (Sin identificar especie), ácaros y cuerpos extraños. Se concluye que si bien las hojas de coca presentan concentración de bacterias con valores fuera de las permitidas para alimentos de este tipo, preocupa la alta contaminación con hongos, parásitos y cuerpos extraños como piedrillas, tela de araña, cabellos.


Considering the veracity of the benefits of the coca leaf and its trade as a ready food for human consumption;This study aims to determine the concentration of aerobic mesophilic bacteria (BAM) and fungi, and identify parasites and fungi in dry coca leaf Yungas and Chapare. A descriptive cross-sectional study was performed. 74 sheet samples Chapare and Yungas coca studied, the BAM/g were quantified grown on trypticase soy agar, quantified and identified fungi after Sabouraud agar culture and parasites were observed by microscopy. A concentration of 3.36*10(7) in the Yungas sheet was obtained: compared to 7.33*10(7) CFU/g in the Chapare: both out of range as IBNORCA; the level of fungi in the Yungas was 1,937,287 CFU/g in the Chapare: 1,955,255 CFU /g, values higher than allowed under the IHR food of the Chilean Norm, they were identified: Aspergillus Terreus, Aspergillus fumigatus, Aspergillus niger, Aspergillus nidulans, Mucor, Rizhopus sp, Fusarium sp (only in the Chapare shown), Aspergillus fumigatus,Aspergillus niger, Fusarium oxysporum, Penicillium citreovirens, Penicillium spinulosum, Penicillium sp., and yeasts (Unidentified species), mites and foreign bodies.We conclude that although coca leaves concentration of bacteria present values outside the permitted for foods of this type, concerned about the high contamination with fungi, parasites and foreign bodies as predrills, spider web, hair.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the effect of three different drinks on the color parameters of four different restorative materials. MATERIALS AND METHODS: Three different composites (Filtek Ultimate Universal Restorative, Filtek Ultimate Flowable, and Filtek Silorane, 3M ESPE) and a polyacid-modified composite resin material (Dyract XP, Dentsply DeTrey GmbH) were evaluated. Eighty-four disc-shaped specimens of 8 mm in diameter and 2 mm in thickness were prepared (n = 21 each). Color coordinates (L*a*b*, DeltaL*, Deltaa*, Deltab*, and DeltaE*) were measured using a VITA Easyshade Compact (VITA Zahnfabrik) after 24 hr of storage (baseline) and after 30 day of storage in three different beverages of black tea, Coca cola, or water (control) (n = 7). In each beverage, the specimens were stored three times a day, one hr each, for 30 day. The color changes (DeltaE) were calculated and were analyzed by Kruskal-Wallis and Dunn multiple comparison test. RESULTS: The color difference (DeltaE*) of the resin materials ranged between 1.31 and 15.28 after 30 day of immersion in the staining solutions. Dyract XP in Coca cola (15.28 +/- 2.61) and black tea (12.22 +/- 2.73) showed the highest mean DeltaE* value after 30 day, followed by Filtek Ultimate Universal Restorative (5.99 +/- 1.25) and Filtek Ultimate Flowable (4.71 +/- 1.40) in black tea (p < 0.05). CONCLUSIONS: The compomers displayed unacceptable color changes at the end of 30 day in all beverages. Among resin composites, the silorane based composite exhibited relatively good color stability than the others. Filtek Ultimate Universal Restorative and Filtek Flowable showed similar color changes in all beverages.

RESUMO

El objetivo del estudio fue evaluar la efectividad del uso del mate de coca en la reducción el estrés laboral en administrativos de la Facultad de Medicina Humana de la Universidad de San Martín de Porres, sede Lima, en el segundo semestre 2014. Se aplicó el cuestionario para la detección del estrés laboral de la OIT/OMS en los 71 administrativos de la institución; de ellos, 34 tenían estrés laboral, pero 20, cumplieron con los criterios de inclusión y exclusión. Se dividieron en dos grupos, experimental y control, empleando randomización simple. El primero, ingirió por 15 días mate de coca y el otro, agua. En el día 16, período de lavado, se les aplicó el instrumento. En el día 17, se realizó el cruce de los grupos, invirtiéndose la asignación de tratamientos, por 15 días más. En el día 31, se volvió a evaluar el nivel de estrés laboral. Se utilizó el análisis de Wilcoxon para comparar los grupos experimento antes y después, y la prueba U de Mann Whitnney para comparar los grupos experimental y control. No se encontró efectividad en el uso del mate de coca para la disminución de los niveles de estrés laboral en los sujetos de estudio. Se necesitan más estudios al respecto. Se recomienda fomentar la salud mental en el trabajo, utilizando intervenciones ligadas a la medicina tradicional y desarrollando guías para la reducción del estrés laboral, utilizando un mayor número de individuos.

RESUMO

Aborda as questões socioculturais que envolvem o uso da folha de coca nas regiões andina e amazônica. O estudo é de natureza teórica, sendo privilegiados artigos científicos e entrevistas com profissionais conceituados em revistas e jornais. Os resultados da pesquisa sugerem que a associação indiscriminada da coca à cocaína e, consequentemente, ao narcotráfico, parte de um preconceito construído historicamente que se sobrepõe às raízes históricas e culturais do uso milenar da planta. Cabe à psicologia, como ciência, romper o silêncio frente às questões indígenas e compreender a dinâmica dos processos socioculturais desses povos para se fazer atuar em espaços que exigem tratamentos diferenciados.


The article focuses on the sociocultural issues associated with the use of coca leaves in the Andes and Amazon regions. Approaching from a theoretical perspective, it explores scientific articles and magazine and newspaper interviews of distinguished professionals. The study's findings suggest that the tendency to indiscriminately link coca to cocaine, and consequently to drug-trafficking, stems from a historically constructed bias that eclipses the historical and cultural roots of the age-old use of this plant. It is up to psychology as a science to break the silence surrounding indigenous issues and come to understand the dynamics of these peoples' sociocultural processes so that it can figure in spaces where differentiated treatment is required.

RESUMO

OBJECTIVES: The aims of this in vitro study were (1) to assess the erosive potential of several children's beverages in comparison to cola and orange juice, by using an in vitro pH-cycling model, and (2) to investigate the factors related to dental erosion caused by the beverages. METHODS: Eight different children's beverages (Chorongi, Capri-sun, Grateful nature wisdom, I-kicker, Koal-koal koala, My friend pororo, Qoo, and Strong zzanggu), Cola, and an orange juice, which are available in the Korean market, were used. To characterize each test beverage, the pH, titratable acidity to pH 7.0, concentration of calcium and phosphorus, and degree of saturation with respect to hydroxyapatite (DS(HAP)) were analyzed. Erosive potential of the test beverages was assessed by the depth of enamel loss observed in specimens subjected to pH cycling for 8 days. This cycle consisted of exposure to each beverage for 20 min, thrice daily, and to a remineralizing solution every day. The correlation between the depth of the enamel loss and the chemical properties of the beverages was assessed by Spearman's rank correlation coefficients and multiple linear regression tests (P<0.05). RESULTS: The depth of enamel loss caused by the beverages was found to vary from 0.11 to 105.47 microm. Enamel loss with all the children's beverages tested was lesser compared to that with Cola (P<0.05) but was similar or greater than that with orange juice, except in one beverage. The pH, concentration of calcium, and DS(HAP) were significantly correlated with the depth of enamel loss (rho=-0.842, rho=-0.796, and rho=-0.867, respectively; P<0.01). Multiple regression analysis showed that pH and concentration of calcium were impact variables for the erosive potential of test beverages (P<0.05). CONCLUSIONS: The children's beverages tested had lower erosive potential than Coca Cola, but five (I-kiker, Grateful nature wisdom, Qoo, Capri-sun, and Chorongi) of them had higher erosive potential than orange juice. Moreover, among the chemical properties of beverages, significant factors affecting enamel loss were pH value and concentration of calcium.

RESUMO

Mediante la investigación realizada, se puede conocer la voluntad política de revalorizar y dignificar a la hoja de coca, promocionando sus valores histórico-culturales e impulsando los procesos de industrialización y despenalización de la hoja de coca para lograr la comercialización lícita. Además de desarrollar acciones orientadas al cambio de su status jurídico en el marco de las Convenciones Internacionales sobre la materia. A tal efecto se desarrollan las dimensiones histórico-cultural, científica, diplomáticolegal, económico-industrial y medio-ambiental de la hoja de coca. También se puede ver y reconocer las propiedades medicinales, terapéuticas, curativas y paliativas de la hoja de coca, así como sus facultades de complemento nutricional y energético, en base a los estudios sobre el valor de la coca. Se puede ver también, varios testimonios de las personas que año tras año usaron la hoja de coca como un alimento sustantivo, tanto así que los galenos recomiendan el consumo de la medicina a base de la hoja coca. En este marco, el Gobierno boliviano ha iniciado acciones diplomáticas en los planos bilateral y multilateral, con el propósito de contar con la aceptación y respaldo de la comunidad internacional. Se trata también de impulsar la industrialización y comercialización de la hoja de coca en diferentes productos medicinales, farmacéuticos, complementos nutricionales y otros derivados, aprovechando sus propiedades terapéuticas, valores vitamínicos, minerales y alcaloides naturales.

RESUMO

Con el fin de detectar la presencia de benzoilecgonina en orina de consumidores de té de coca, se realizó un estudio piloto analizando muestras de orina a 10 voluntarios sanos, no consumidores de cocaína, antes de ingerir la infusión de té de coca (Nasa Esh´s Coca Nasa), y las recolectadas hasta las 48 horas después de la ingestión, de una toma única de 100 mL el mismo día. El análisis se realizó por métodos de inmunoensayo, cualitativo, mediante pruebas rápidas Acu-check, y semicuantitativo AxSYM Cocaine Metabolite, basado en In munoensayo de Fluorescencia Polarizada (FPIA). Antes de la ingestión de la infusión por los métodos cualitativos y semicuantitativos las muestras recolectadas resultaron negativas, después de haber ingerido la infusión, por ambos métodos se detectó concentraciones de benzoilecgonina desde la primera hasta las 48 horas con diversas variaciones entre las muestras, observándose excelente concordancia entre los métodos para la determinación de benzoilecgonina en orina. En este estudio, se concluyó que existe la presencia de benzoilecgonina en muestras de orina de consumidores de té de coca. Los métodos utilizados sólo proporcionan resultados preliminares, se recomienda utilizar unos más específicos a fin de encontrar parámetros que permitan discriminar individuos que hayan ingerido infusión de té de coca, de aquellos que son adictos a la cocaína. Además, es importante prevenir a los consumidores de té de coca sobre el riesgo de detección de benzoilecgonina en orina dentro de las primeras 24 a 48 horas y las implicaciones que trae consigo tales hallazgos de laboratorio.


In order to detect the presence of benzoylecgonine in urine of consumers of coca tea, a pilot study was conducted by analyzing urine samples from 10 volunteers not cocaine users, be fore drinking the coca tea infusion, and collected until 48 hours after ingestión of a single shot (100 mL) the same day, The analysis was performed by immunoassay qualitative methods, using fast Acu-check tests, and semi quantitative automated equipment Abbott Axsym System, based on fluorescence polarization immunoassay (FPIA). Before ingestion of the infusion for qualitative and semiquantitative methods for samples collected were negative, and after drinking the tea, for both methods, concentrations of benzoylecgonine was detected from the first to 48 hours with several variations between samples, observed excellent agreement between the methods for the determination of benzoilecgonine in urine. In this study, we concluded that there is the presence of benzoylecgonine in urine samples from consumers of coca tea. According to the methods used provide only preliminary results, we recommend using a more specific in order to find parameters to discriminate individuals who have ingested coca tea infusions of dose that are cocaine addicts, In turn, it is important to prevent cosumers coca tea on the risk of detection of benzoylecgonine in urine within the first 24 to 48 hours and the implications it brings such laboratory findings.

RESUMO

Situs inversus totalis (SIT) is very rare autosomal recessive condition, and patients with SIT have complete mirror image reversal of the thoracic and abdominal viscera. There have been no case reports of esophageal bezoar in a patient with situs inversus totalis. Bezoars are retained concretions of indigestible foreign material, including food material, vegetable material and hair, and they are usually founded in the stomach, small intestine and rectum. Esophageal bezoars are very rare, but they are known to occur in patients with anatomical defects or esophageal motility disorders. The treatment of esophageal bezoar is usually based on endoscopic fragmentation and extraction, dissolution with papain, cellulose, pancreatic enzyme and/or Coca cola. We report here on a case of an endoscopically treated primary esophageal bezoar in a patient with situs inversus totalis, and the patient experienced no complications from the treatment.

RESUMO

Se analizan los resultados de un estudio probabilístico en una zona de extrema pobreza donde se aplicó una metodología etnográfica para la identificación del consumo de pasta base de cocaína. La prevalencia de vida para la población general de la comunidad estudiada fue de 13,2. En la población de varones de 14 a 30 años, la prevalencia fue del 51,1. Dentro de la misma situación de indigencia, el mayor consumo se asoció con las mayores carencias. Los datos muestran como la compulsividad del consumo de pasta base acentúa el desplazamiento de los grupos vulnerables a los límites de la supervivencia social.


The results of a probabilistic study performed in an extremely poor area where an ethnographic methodology was applied for the identification of cocaine paste consumption are analyzed. The studied community's general population's life prevalence was of 13, 2. Prevalence was 51, 1 within the male population between 14 and 30 years old. Within the same poverty situation, greater consumption was associated with greater deficiencies. Data shows how cocaine paste consumption compulsion accentuates the displacement of the most vulnerable groups towards the limits of social survival.

RESUMO

A coca surge, na crônica-carta de Guaman Poma de Ayala ao rei da Espanha, a partir de peculiares eventos da história do Peru. Na visão do escritor indígena e cristão (entre os sécs. XVI e XVII), a planta psicoativa aparece num passado não muito distante, por meio dos índios da montaña (as serras orientais cobertas pela selva quevem da planície amazônica), numa história de idolatria do arbusto. Mas o vício de mastigar a folha da coca é inventado pelos incas na conquista dessa região (o Antisuyo). A história de Guaman Poma pode entreter, mas também demonstra a seriedade do cronista em apontar para a relação entre os vícios mundanos com umgrande pecado, a idolatria de alguns índios – mas são exceções para o fato, segundo o cronista, da verdadeira cristandade desde muito tempo na serra (nas altitudes mais temperadas), que recebe de fora o “vício de comer coca”. É interessante notar que essas histórias de Guaman Poma também indicam códigos indígenas de compreensão e manipulação dos eventos, como será discutido abaixo, com apoio, ainda, da análise da crônica de outro indígena do Peru, e contemporâneo, Santa Cruz Pachacuti.
