[Esophagitis associated with use of alendronate in 5 postmenopausic patients]. / Esofagitis asociada con el uso de alendronato en 5 pacientes posmenopáusicas.

The bisphosphonate, alendronate sodium (e.g. Fosamax) is a bone resorption inhibitor used to treat postmenopausal osteoporotic women and osseous Paget's disease. Esophagitis is one of the adverse effects (AE) associated to its use. Five (5) patients with alendronate-associated esophagitis assisted in the Gastroenterologic Center, Rosario, Argentina, between October 1996 and December 1999 are described. The aim is to correlate the clinical, endoscopic and histopathological findings in 5 women (ages 57-71) complaining for upper digestive symptoms (dysphagia, epigastralgia, retrosternal pain.). All had osteoporosis treated with alendronate 10 mg/day and received detailed instructions about how to take the medication. The time from the beginning of alendronate intake and the appearance of the symptoms was elapsed 30, 35, 67, 85 and 90 days. The esophagitis was graded according to the Savary-Miller Classification. The videoscopy disclosed esophagitis of III and IV grades. Three patients had also antral and antroduodenal lesions, one of them associated to Helicobacter Pylori. Anatomopathologic findings confirm esophagitis and esophagic ulceration. Some authors claim that bisphosphonates as a new class of gastrotoxic drugs with AE similar to aspirin. Even when it is administrated according to the instructions of the manufacturers it should be used with caution. Our contribution emphasize the importance of this AE and suggest measures to diminish or suppress them, and take into consideration those patients who are taking aspirin. With alendronate, as well as with other potentially corrosive agents, is very important to take in mind the measures to prevent AE.

[Seroprevalence of helicobacter pylori infection in the republic of Argentina: influence of age, sex, socioeconomic level, geographical area, and health infrastructure. Multicenter study by the Club Argentino del Estomago y Duodeno]. / Seroprevalencia de la infección por Helicobacter pylori en la República Argentina: influencia de la edad, sexo, nivel socio-económico, área geográfica e infraestructura sanitaria.

Helicobacter pylori (Hp) infection affects almost half of the world population, it is almost a pandemia, and has been associated to poverty in underdeveloped countries. The Club Argentino del Estómago y Duodeno decided to fulfill the lack of information upon this subject in Argentina designing a seroprevalence, multicentric, prospective study performed in voluntary adults donors in blood banks and in children seen during normal growth controls. Seven hundred and nineteen individuals were evaluated, 645 of them were included: 178 children (age 0-18 years) and 467 adults. In all cases a serological IgG Hp test (Flex-Pack Abbott) was performed and an epidemiological questionnaire was completed by a physician. General prevalence of Hp infection was 44.8% of individuals. In the paediatric population prevalence was 15.7% and in adults 55.9%. The highest prevalence was observed in the fifth decade: 64%. In concordance with other similar studies carried out in different countries, we may conclude that the risk of acquisition of Hp infection is directly related to age, area of residence, social-economical status, sanitary facilities, and educational level reached. Even though the prevalence of Hp infection in Argentina is intermediate between highly developed and underdeveloped countries, the number of people infected is very high and the incidence of Hp-associated pathologies in the future represents a formidable task for gastroenterologists and sanitary authorities.

La infección por Helicobacter pylori (Hp) afecta a casi la mitad de la población mundial, está considerada como una pondemia y se asocia fundamentalmente a la carencia de infraestructura sanitaria, el subdesarrollo y la pobreza. El Club argentino de Estómago y Duodeno decidió llenar una carencia en las estadísticas nacionales coordinando un estudio de seroprevalencia del Hp en la República Argentina, multicéntrico, prospectivo, en adultos dadores de sangre voluntarios en bancos de sangre con patologías no digestivas y en pacientes pediátricos que concurrían a consultorio del niño sano. Se evaluaron 719 sujetos, de los que fueron incluídos 645, de los cuales 178 eran niños y 467 adultos. A todos se les praticó el test serológico para detección de anticuerpos IgG anti=HP Flexpack (Abbott) consignadose los datos epidemiológicos en una planilla en el momento. La prevalencia general fue del 44.8 por ciento. La prevalencia en el grupo pediátrico fue del 15,7 por ciento. La prevalencia del grupo de adultos fue del 55.9 por ciento. La prevalencia mayor se observó en la 5a década de la vida: 64 por ciento. Al igual que lo encontrado en estudios de prevalencia en otros países, de acuerdo a nuestros resultados podemos inferir que los riesgos de adquirir la infección están en relación directa con la edad, la zona de residencia, la vivenda, la infraestructura sanitaria y el nivel de enseñanza alcanzado. Si bien la tasa de prevalencia de infección por Hp en nuestro país es intermedia entre la de los países desarrollados y la de los en vía de desarrollo, la cantidad de infectados es muy alta por lo que la incidencia esperada de enfermedades asociadas al Hp en los próximos años será un verdadero desafío para los gastroenterólogos y sanitaristas.

[Post-treatment assessment of Helicobacter pylori eradication, by polymerase chain reaction in gastric biopsies]. / Evaluación de la erradicación postratamiento del Helicobacter pylori por reaccion en cadena de la polimerasa en biopsias gástricas.

BACKGROUND: The pre-treatment detection of H.p. in the stomach of patients is easily achieved with routine methods. Conversely, with conventional methods, it is difficult to detect the presence of H.p. after treatment. OBJECTIVE: To estimate the actual percentage of successfully treated patients by using a more sensitive and specific technique (PCR) in the same biopsies where standard methods were negative for H.p. MATERIALS AND METHODS: We selected 97 treated patients (31 Gastric Ulcers/66 Duodenal Ulcers, 62 male/35 female, age: 49 +/- 14 years), in whom success of treatment was defined by histological means and CLO Test. In the same gastric biopsies H.p-DNA PCR was performed. Different therapeutic schemes were utilized, but all included Proton Pump Inhibitors + ATB. Eight weeks after the end of the treatment, without medication, the patients were controlled as follows: 5 biopsies per patient, 2 of antrum, 2 of corpus (in different zones) and 1 for CLO Test. H.p. eradication was defined on histological grounds (gastric biopsy histology: 10% formaldehide buffer fixation, paraffin inclusion, Giemsa, HE staining and inmunohistochemistry), CLO Test (Delta West Pty. Ltd. Bentley, Australia) and by the absence of H.p.-DNA by PCR (amplification of a 296 bp of the species-specific antigen of H.p. and visualization of the amplified product in agarose gel with Ethidium Bromide and UV light). RESULTS: [table: see text] CONCLUSIONS: The higher sensitivity of PCR (10(3) fold more than conventional methods) allowed us in this group of patients to detect 13% of false eradication. It would be necessary to follow up this group of patients in order to know whether they develop or not clinical symptoms and/or histological evidence of disease. If such a case PCR could become an important tool for treatment evaluation.

Evaluacion de la erradicacion postratamiento del Helicobacter pyloripor reaccion en cadena de la polimerasa en biopsias gastricas / Post-treatment control of Helicobacter pylori erradication, by polymerase chain reaction in gastric biopsies

Introducción: La detección del H.p. en el estómago de pacientes vírgenes de tratamiento ha sido solucionada; un aspecto no resuelto, al menos en nuestro medio, es la pesquisa del H.p. luego de la terapéutica, para asegurar su erradicación. Objetivos: Utilizar una metodología sensible y específica para evaluar la presencia del H.p. en biopsias gástricas postratamiento, comparándola con otras técnicas similares clásicas. De esa manera, aumentando la precisión en el diagóstico, se podrá diferenciar la recrudescencia (falsa erradicación) de la reinfección y conocer el exacto porcentaje de curación. Materiales y Métodos: La PCR para H.p. fue realizada en 97 pacientes (62 hombres y 35 mujeres) con edad propedio de 49 años (+/- 14), en los cuales ya se había confirmado la erradicación por histología-Giemsa más CLO TEST. La metodología fue la siguiente: se realizaron 5 biopsias gástricas endoscópicas por paciente, 2 de antro, 2 de cuerpo, y 1 para CLO; todos los pacientes fueron estudiados luego de 6 ou 8 semanas de terminado el tratamiento y durante ese período no recibieron ninguna medicación. La metodología fue: las biopsias gástricas fueron fijadas en formol buffer al 10 por ciento, incluídas en parafina, y se colorearon con Giemsa y hematoxilina-eosina. El CLO TEST usado fue de Delta West Pty. Ltd. Bentley. La PCR se efectuó amplificando un fragmento de 296 pares de bases correspondiente al gen codificante del antígeno especie especifico de Helicobacter pylori, y la visualización del producto amplificado se realizó por electroforesis en gel de agarosa teñido con bromuro de etidio y U.V. Resultados: ninguno de estos pacientes presentaba úlcera gástrica o duodenal en el momento del control.Conclusiones: La PCR puede detectar secuencias de ADN especificas del H.p., incluso en su forma cocoide de resistencia, como se observan postratamiento. Las tinciones más utilizadas en biopsia (Giemsa/W-S) detectan aproximadamente 100000 microorganismos por ml; la PCR puede detectar 100, vale decir que es tres órdenes más sensible que la metodología clásica. En nuestra experiencia detectamos un 13 por ciento de falsos erradicados, los cuales clínicamente deberán ser considerados como recrudescencia y no como reinfección.

Laparoscopic insemination of frozen-thawed semen into one or both uterine horns without regard to ovulation site in synchronized Merino ewes.

Synchronized ewes (n = 217) were bred by laparoscopic insemination of frozen-thawed semen from 1 of 3 rams. The ewes were bred by either a double (110 ewes) or single horn (107 ewes) technique without regard to the site of ovulation. There was no difference in the percentage of ewes pregnant to either the single or double horn breeding technique. There was a significant effect of sire, with 1 ram producing a higher pregnancy rate in the ewes and 1 ram producing a significantly lower pregnancy rate when compared to the total pregnancy rate for all the ewes (P < 0.05). Thus, the single horn breeding technique is presented as an alternative technique for use in the commercial breeding of ewes by laparoscopic insemination of frozen-thawed semen.

Estudio multicentrico para la evaluacion de la reproducibilidad en la medicion del umbral sensorial a la distension rectal / Multicenter study for the evaluation of the reproducibility in the measurement of rectal sensorial threshold

Una forma simple para la evaluación de los umbrales sensoriales del recto ha sido la determinación, mediante la distensión escalonada con un balón intrarrectal, de los volúmenes capaces de generar deseo evacuatorio y dolor. Seis grupos pertenecientes al Círculo de la motilidad, efectuaron en 14 pacientes (7M y 7H edad: 51 DS: 10,1). estudios del volumen de deseo defecatorio (VDE) y del volumen de tolerancia máxima a la distensión rectal (VTM). Los estudios se repitieron con un intervalo no menor de 24 horas en cada uno de los sujetos. El estimado de precisión, estableció un coeficiente de variación (CV) para el VIDE de 10,23 por ciento (2 CV = 20,45 por ciento), lo que no puede ser considerada como una reproducibilidad aceptable. En cambio el CV para el VTM, fue de 1,44 por ciento (2 CV = 2,88 por ciento), lo que s'i puede ser considerada una muy buena reproducibilidad. El VTM es una variable confiable que puede permitir la discriminación sensorial noscioceptiva del recto, pudiendo ser usada para la evaluación clínica y farmacológica

[Psychological differences between ulcer and non-ulcer dyspeptic patients]. / Diferencias psicológicas entre pacientes ulcerosos y dispépticos no ulcerosos.

The existence of differences in the psychological profile of 39 endoscopically evaluated patients with ulcer (U) and non ulcer (NU) dyspepsia were examined. There were 21 U and 18 NU subjects. Cigarette smoking, intake of alcohol, coffee, mate, aspirin and NSAID were recorded, but there were no significant differences between the two groups. Personality traits were determined by the Rorschach Test, considering psychological profile (introversive, extroversive, self-restrained), impulse and emotion control (do not allow their expression, impulsive, adequately conveyed) and level of social adaptation (low, normal, high). U and NU subjects experienced a similar number of potentially stressful life events. However, U patients perceived their events more negatively. Although no one type of "ulcer personality" was found consistently, ulcer patients tended to be more introversive and they had a better social adaptation than NU.
