ABSTRACT

OBJECTIVE: To establish nomograms for linear measurements of the frontal and occipital horns of the lateral ventricle and their relationship, in pregnant patients between 18 and 40 weeks of gestation and having attended 2 units of Maternal Fetal Medicine in Bogotá-Colombia. METHODOLOGY: A descriptive cross-sectional study with an analytical component was carried out on pregnant patients who utilized the ultrasound services at 2 Maternal-Fetal Medicine units in Bogotá, between 18 and 40 weeks of pregnancy who underwent measurement. From the anterior and posterior horns of the lateral ventricles, the fronto-occipital ratio was calculated at each gestational week, and nomograms were created for each of these variables. RESULTS: Nine hundred and seventy-eight patients were included in the study. The distance of the frontal horns ranged between 6.9 and 51.6 mm with a mean of 19.1 ± 5.8 mm; that of the occipital horns had a measurement between 8.7 and 53 mm with a mean of 28, 1 ± 8.9 mm; on the other hand, the fronto-occipital ratio (FOR) yielded a mean of 0.365 ± 0.067 (0.136-0.616) without bearing any relation to gestational age. The trend of normal values for the studied population is displayed, plotted in percentile curves and nomograms for each gestational age. CONCLUSION: The measurement of the frontal and occipital horns, and the calculation of the fronto-occipital relationship is technically possible between 18 and 40 weeks, finding that the anterior and posterior horns have a positive linear relationship with gestational age. Contrarily, the FOR does not correlate with the gestational age, it was possible to establish a table of percentiles that allows determining the normal values for these measurements during pregnancy.

ABSTRACT

Introduction: In the mid-fifties, Colombia adopted and implemented the Malaria Eradication Campaign (MEC), which has not been evaluated yet in the country. Objective: To evaluate the results achieved during the attack and consolidation phases of the MEC regarding malaria transmission in Colombia between 1959 and 1979. Materials and methods: We conducted a descriptive and retrospective study based on the malariometric and operational results of the MEC in Colombia from 1959 to 1979 compiled from the archives of the Ministry of Public Health. We used the criteria defined by the WHO Expert Committee on Malaria. The information was stored, tabulated, and analyzed based on the malariometric indicators we developed. Results: In the short-term eradication period (1959-1969), a reduction of 94% (4,172) in transmission was achieved during the first year of the attack phase (1959) while in the last year (1962), there was an 88% (8,426) reduction of the accumulated load of cases compared to the annual average of the 1950s (71,031). These low levels of transmission were maintained until the end of 1969. During the intensification period of control of the eradication (1970-1979), there was an increase in malaria endemicity and a resurgence of the epidemic transmission. Due to financial problems affecting the regularity of the operations, Colombia was unable to sustain the results and achieve an interruption of transmission, which resulted in a resurgence of cases during the attack and consolidation phases. Conclusions: The campaign did not achieve the goal of interrupting malaria transmission in the national territory but there was marked control in areas of medium and low intensity.


Introducción. A mediados de la década de 1950, el país adoptó e implementó la Campaña de Erradicación de la Malaria (CEM), sin que hasta ahora se haya hecho su evaluación. Objetivo. Evaluar los resultados alcanzados en las fases de ataque y consolidación de la campaña de erradicación de la malaria en Colombia, entre 1959 y 1979. Materiales y métodos. Se hizo un estudio descriptivo y retrospectivo de los resultados "malariométricos" y operacionales de la CEM en Colombia entre 1959 y 1979 a partir de los datos recopilados de los archivos del Ministerio de Salud Pública. Se utilizaron los criterios establecidos por la Organización Mundial de la Salud (OMS) relacionados con las fases de un programa de erradicación de malaria. Se almacenó, tabuló y analizó la información, y se elaboraron y aplicaron indicadores malariométricos. Resultados. En el periodo de erradicación a corto plazo (1959-1969), durante el primer año de la fase de ataque (1959), se alcanzó una reducción de la transmisión del 94 % (4.172) y, en el último año (1962), una disminución del 88 % (8.426) en la carga acumulada de casos comparada con el promedio anual de la década del 50 (71.031); estos bajos niveles de transmisión se mantuvieron hasta finales de 1969. En el periodo de intensificación del control para la erradicación (1970-1979), se produjo un incremento de la endemia y resurgió la transmisión epidémica. Debido a problemas financieros que afectaron la regularidad de la operación para mantener los resultados, y no habiéndose logrado la interrupción de la transmisión, se observó un resurgimiento de casos en las fases de ataque y consolidación. Conclusiones. La campaña no logró la meta de interrupción de la transmisión de la malaria en el territorio nacional, pero sí se consiguió un acentuado control en áreas de mediana y baja intensidad.
