Donovanosis, reporte de caso
La Donovanosis es una enfermedad ulcerativa crónica y progresiva que ataca por lo común la región genital, es producida por el Calymmatobacterium granulomatis, bacteria Gram negativa. La Azitromicina ha emergido como la droga de elección para su tratamiento. Se presenta un caso de Donovanosis en un varón de 46 años, quien tenía relaciones heterosexual y homosexual, el cuál presento papula anal que evoluciono a una úlcera crónica, le realizan el diagnostico de tumoración anorrectal a descartar una neoplasia anorrectal y le realizan colostomía. El retardo en la sospecha clínica en un área no endémica concluyo con su diagnóstico con un extendido en lámina para microscopia con coloración Giemsa
First lacustrine varve chronologies from Mexico: impact of droughts, ENSO and human activity since AD 1840 as recorded in maar sediments from Valle de Santiago
Recomendaciones para la buena práctica de la medicina en anestesiología
At present, the Anesthesiology is recognized as a medical discipline
and the activities of the anesthesiologist are wide, since it interferes in all
the processes that happen during the anesthetic - surgical act. The most
common reason of damages or serious complications they are associated
with faults in the suitable ventilation of the patient. The aim of the present
work is to generate specific and general recommendations directed to
specialists of Anesthesiology, from the analysis of the complaints received
in the CONAMED. There were analyzed all the complaints received for the
specialty of anesthesiology from June, 1996 to May, 2001.
Sociodemographic variables were included, information about institution
of health and motive of complaint among others. There was included
information of the Medical Integral Valuation, to obtain the type of used
anesthesia. For the analysis descriptive statistics was used, for this intention
it was used SPSS 10.1.
Results: there was analyzed a whole of 97 complaints, 74.2 % of the
complaints corresponded to the female sex, average of age 34.3 years, the
major proportion of the complaints were to institutions of Social Security
(67.0%). The proportion of malpractice for type of institution was of 75 %
in the private roads, 57.4 % in Social Security and 52.6% in the Public
Services. Problems identified with major frequency in the complaints with
malpractice were in order: dural puncture, encephalopathy ischemic and
cerebral irreversible damage and injury of nervous roots. Five deaths related
with anesthesia were identified. The results obtained in the present work
as for the problems in the practice of anesthesiology are very similar to the
reported ones in the literature and a proportion of cases they can be
prevenibles across a better training and supervision of the procedures that
are realized.En la actualidad, la Anestesiología se reconoce como una disciplina
médica y las actividades del anestesiólogo son amplias, ya
que se involucra en todos los procesos que ocurren durante el acto
anestésico-quirúrgico. La causa más común de daños o complicaciones
serias están asociadas con fallas en la ventilación adecuada
del paciente. El objetivo del presente trabajo es emitir recomendaciones
generales y específicas, dirigidas a los especialistas de
Anestesiología, a partir del análisis de las quejas recibidas en la
CONAMED. Se analizaron todas las quejas recibidas en la CONAMED
para la especialidad de anestesiología de junio de 1996 a mayo de
2001. Se incluyeron variables sociodemográficas, de la institución
de salud y motivo de queja entre otras. Se incluyó información de
la Valoración Médica Integral, para obtener el tipo de anestesia
utilizada. Para el análisis se empleó estadística descriptiva, para
este propósito se utilizó el paquete estadístico SPSS 10.1.
Resultados: se analizaron un total de 97 quejas, 74.2% de las
quejas correspondieron al sexo femenino, promedio de edad pacientes
34.3 años, la mayor proporción de las quejas correspondió
a instituciones de Seguridad Social (67.0%). La proporción de mala
práctica por tipo de institución fue de 75% en las privadas, 57.4%
en seguridad social y 52.6% en servicios públicos. Los problemas
identificados con mayor frecuencia en las quejas con mala práctica
fueron: perforación de duramadre, seguida por la encefalopatía
anoxoisquémica, el tercer lugar para daño cerebral irreversible y
lesión de raíces nerviosas. Se identificaron 5 defunciones relacionadas
con la anestesia. Los resultados obtenidos en el presente
trabajo en cuanto a los problemas en la práctica de la anestesiología
son muy semejantes a los reportados en la literatura y una proporción
de casos pueden ser prevenibles a través de una mejor capacitación
y supervisión de los procedimientos anestésicos que se
realizan
First lacustrine varve chronologies from Mexico: impact of droughts, ENSO and human activity since AD 1840 as recorded in maar sediments from Valle de Santiago
We present varve chronologies for sediments from two maar lakes in the Valle de Santiago region (Central Mexico): Hoya La Alberca (AD 1852–1973) and Hoya Rincón de Parangueo (AD 1839–1943). These are the first varve chronologies for Mexican lakes. The varved sections were anchored with tephras from Colima (1913) and Paricutín (1943/1944) and 210Pb ages. We compare the sequences using the thickness of seasonal laminae and element counts (Al, Si, S, Cl, K, Ti, Mn, Fe, and Sr) determined by micro X-ray fluorescence spectrometry. The formation of the varve sublaminae is attributed to the strongly seasonal climate regime. Limited rainfall and high evaporation rates in winter and spring induce precipitation of carbonates (high Ca, Sr) enriched in 13C and 18O, whereas rainfall in summer increases organic and clastic input (plagioclase, quartz) with high counts of lithogenic elements (K, Al, Ti, and Si). Eolian input of Ti occurs also in the dry season. Moving correlations (5-yr windows) of the Ca and Ti counts show similar development in both sequences until the 1930s. Positive correlations indicate mixing of allochthonous Ti and autochthonous Ca, while negative correlations indicate their separation in sublaminae. Negative excursions in the correlations correspond with historic and reconstructed droughts, El Niño events, and positive SST anomalies. Based on our data, droughts (3–7 year duration) were severe and centred around the following years: the early 1850s, 1865, 1880, 1895, 1905, 1915 and the late 1920s with continuation into the 1930s. The latter dry period brought both lake systems into a critical state making them susceptible to further drying. Groundwater overexploitation due to the expansion of irrigation agriculture in the region after 1940 induced the transition from calcite to aragonite precipitation in Alberca and halite infiltration in Rincón. The proxy data indicate a faster response to increased evaporation for Rincón, the lake with the larger maar dimensions, solar radiation receipt and higher conductivity, whereas the smaller, steeper Alberca maar responded rapidly to increased precipitation
