Objective: Coarctation of the aorta can be treated surgically or with balloon angioplasty. The objective of our study was to describe the results after percutaneous balloon angioplasty with or without stent implantation for coarctation of the aorta and establish the incidence of recovery during follow-up. Method: Cohort study. 89 patients of any age where included in a follow up period of nine years. Results: Of the 89 patients included in the study, 69.0% were male. The mean follow-up for all participants was 33.66 months. 32.5% of the patients had a stent implanted during the angioplasty procedure; of which 24.1% suffered recoarctation during follow-up. In the group without stent implantation, 36.6% suffered recoarctation. There was not significant difference in the survival curves of the two groups (p = 0.899). Conclusions: Stent implantation during balloon angioplasty to treat aortic coarctation did not influence in the incidence of aortic recoarctation; but factors such as preangioplasty arterial hypertension and the final angioplasty gradient > 20 mmHg is associated with aortic recoarctation.

Introduction: Birth defects affect 2-3% of births, contributing an important burden to the causes of infant morbidity and mortality during the first five years of life. In Colombia, they are the leading cause of infant mortality according to reports from the National Administrative Department of Statistics (DANE) 2011. Objective: To describe the state of health and presence of barriers in the health care of children with congenital defects born between 2011 and 2017 in two institutions in the city of Cali. Materials and methods: A descriptive cross-sectional observational study was carried out. Those born between January 2011 and December 2017 with at least one congenital defect were included, who were followed up by telephone. Results: Of 54.193 births in the period analyzed, 1.389 (2.56%) newborns had at least one congenital defect. All cases were classified according to the prognostic scale and 881 were included in the follow-up. The most frequent congenital defect was congenital cardiac malformation with 88 (9.99%) cases, in the second place malformation/defect of the kidney with 73 (8.29%) cases, thirdly, Down Syndrome with 72 (8.17%) cases and fourth, testicular abnormalities with 56 (6.36%). Of the 454 cases with effective follow-up, 161 (35.46%) of the caregivers stated that they had presented at least one type of barrier in care. Conclusion: Follow-up programs should be implemented for patients with birth defects to contribute on reducing morbidity and mortality. [ABSTRACT FROM AUTHOR]

Objective: To determine the perceived burden and functional status of gastric cancer patients with gastrectomy in a center of cancer in Bogota (Colombia) between 2013 and 2016. Materials and methods: Retrospective description of patients intervened by gastrectomy distributed in three groups: Patients with gastrectomy from 1 to 12 months of surgical intervention, 13 to 14 months and 25 to 36 months. For this, it was used the disease burden perception instrument and the Karnofsky scale. Results: 127 patients were included. 63 from 1 to 12 months, 43 from 13 to 24 months, and 21 from 25 to 36 months of intervention. Gastric adenocarcinoma of intestinal pattern stage III and II predominate. More than 50% of the patients required total gastrectomy and received adjuvant chemotherapy. The majority of participants performed regular activities with mild signs and symptoms, presented low overall perceived burden and functional performance without statistically significant differences between groups. Patients from 1 to 12 months of intervention reported greater levels of physical discomfort. Conclusions: In patients with gastrectomy for gastric cancer, physical symptoms persist such as emotional disturbances, economic difficulties and limitations in the work role, findings to be included in follow-up programs.

INTRODUCTION: the incidence lung cancer has risen 25% in recent years with 10% survival at 5 years. Response to treatment needs to be evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) and conventional measuring methods. PURPOSE: stage response to treatment with the RECIST, comparing such measurements with the conventional radiological method. MATERIAL AND METHOD: we studied 51 patients in the period January 2012 to September 2015 with histological diagnosis of lung carcinoma. RESULTS: statistically significant difference in the RECIST group was observed in the baseline and follow-up studies compared with conventional methods. There was no significant difference between the three measuring methods in baseline and follow-up studies in evaluation of target lesions; we propose that the three measuring methods can be used in evaluating target lesions. Because the T test showed statistically significant difference between baseline and follow-up evaluations of the one-dimensional method, we recommend using it in global evaluation of response to treatment. CONCLUSION: the RECIST are superior to conventional methods because they include non-target lesions, new lesions to assign global response, where the latter was changed to include the aforementioned lesions, altering the classification of response to treatment.

Objective. To evaluate a strategy to monitor the use of drugs in pregnant women in a Colombian municipality. Methods. Drug use study, descriptive type, cross-sectional, prospective collection of information, aimed at identifying medications consumed by pregnant women without a medical prescription. Using a simple random sample with 95% CI and 5% MS, a sample of 155 maternal samples was obtained. Results. A data collection instrument was designed, validated and applied to 169 pregnant women, of whom 152 met four pregnancy controls. The average age was 24.5 years (Min. 13 and Max. 40), live in free union, and only have secondary studies. 42% had their first pregnancy, and 30% had 3 or more pregnancies. The average number of children was 1.0, but 13 of them had more than 3 children. Pregnant women attended 4 controls on average. The selfmedication rate was 21%. The pregnant women consumed 11 products without prescription; 9 synthetic medicines, and 2 medicinal plants. The frequency of consumption of products classified as risk B was 29%, risk C was 33%, and for categories D and X was 38%. Two medicinal plants (Equisetum giganteum L., Pedilanthus tithymaloides L. Poit) with potential risk for pregnancy were identified. Conclusions. The instrument helps to identify characteristics whose control can contribute to safe motherhood, and makes it possible to highlight the use of products with a potential risk for pregnancy.

In Colombia, cervical cancer (CxCa) is one of the main causes of death. Every year, 7,000 cases are diagnosed and 3,300 deaths are recorded. 50% are because of late diagnosis and no access to specialized treatments. Objective: This study aims to monitor women who have had a positive cytological results in a state-owned company in Medellin from 2011 to 2012. Methodology: This is a cross-sectional descriptive study conducted on 277 women who had positive cytological results for lesions suggestive of high grade and/or glandular disorders. This research used stratified systematic sampling, and primary and secondary information sources. SPSS was implemented to systematize data like frequency, central tendency, and dispersion measurements were calculated. A descriptive univariate-bivariate analysis was implemented for sociodemographic and clinical related variables, and those related to the healthcare subjects received. Results: 10.7% of women with high grade or invasive lesions did not complete the treatment. The total monitoring opportunity was 52.3%, and the phases with the longest-waiting times were waiting for appointments for diagnosis and treatment. Conclusion: Despite efforts to improve screening coverage and to actively seek patients with a positive cytology evidenced in the study, there are still obstacles that impede patients' prompt diagnosis and treatment, and this is something that in various cases leads to the progression of the disease and even death.

Background: The incidence of non-microcytic lung cancer has increased 25% in recent years; with 10% survival at 5 years, we need to evaluate response to treatment using the Response Evaluation Criteria In Solid Tumors (RECIST), three-dimensional measurement methods, or both. Objective: Stage response to treatment with RECIST and compare such measurements with those of the three- dimensional and volume radiological methods. Material and method: We studied 11 patients with histological diagnosis of pulmonary carcinoma (except small cell carcinoma) in the period January to September 2013. Results: We observed only one case of concordance between conventional three-dimensional radiological measurements and RECIST criteria; in the rest of the population studied there was a 5 to 43% range of difference between the two measurements. Discussion: In the patients studied we found: in 5 progression of disease, in 3 stability, in 2 partial response, and in only 1 complete response based on RECIST criteria and the three-dimensional method. This shows that uniform protocol is needed to monitor patients with lung cancer, using evaluation by three-dimensional measurements, RECIST, or both. Conclusion: Use of RECIST to classify response in all patients with pulmonary tumors should be considered, regardless of histological subtype and stage of disease, to standardize monitoring and evaluation not only of the target lesion or lesions but of all lesions present (metastasis) for optimum control of treatment.

In order to determine whether hyperuricemia is associated with the progression of chronic cardiorenal compromise (CCC), a retrospective cohort study was performed which included 103 patients in whom CCC was defined as the simultaneous presence of chronic kidney disease (CKD) and chronic heart disease (CHD). CKD progression was defined asa 50% reduction of glomerular filtration rate estimated by the MDRD-4 equation. Hyperuricemia was defined as basal levels of uric acid ≥ 7 mg/dL. None of the studied variables showed association with the progression of CCC or CHD. Independent predictors of CKD progression were basal hyperuricemia (HR 4.41, 95% CI: 1.02-18.94) and SAP in follow-up (HR 1.05, 95% CI: 1.01-1.09). We conclude that hyperuricemia is an independent risk factor for the progression of CKD in patients with CCC. [ABSTRACT FROM AUTHOR]

Prognosis is the prediction of the evolution of a given disease or event of interest and the frequency of occurrence of specific outcomes. The ideal study design to assess prognosis are cohort studies. However many prognostic studies have case-control or case series designs. Prognostic studies should include all participants with the event of interest of a determinate geographical region, to avoid bias. The measurement precision and exactitude of intervening variables and outcomes, the identification of confounding variables and an adequate follow up period, have a great influence on the methodological quality of prognostic studies. Prognosis is usually expressed as survival, disease free or remission free rates. This article provides basic methodological concepts that should be considered when evaluating a prognostic study.

Después del ensayo clínico, el segundo diseño de investigación con mayor calidad de Información es la cohorte. Si bien no se cuenta con la posibilidad de asignación de la maniobra, se tiene la oportunidad de contar con el seguimiento de los sujetos a lo largo del tiempo. Cualquier investigación que intenta explicar el fenómeno de causalidad corre el riesgo de caer en sesgos; sin embargo, las particularidades de los estudios de cohorte intentan evitarlos. Sus principales características son: 1 ser observaclonal, aspecto en que el Investigador solo mide la presencia de la maniobra, característica que divide a los sujetos en expuestos y no expuestos; 2 ser longitudinal, lo que ofrece la oportunidad de seguir al sujeto a lo largo del tiempo, documentando la secuencia temporal de aparición de los componentes del fenómeno de causalidad; 3 tener direccionalidad en las mediciones, lo que genera la existencia de cohortes prolectivas, retrolectivas y retroprolectivas (las primeras son las de mayor calidad por contar con la medición en tiempo real de las variables de interés); 4 ser comparativo.

The second research design with higher quality of information, only after the clinical trial is the cohort, although it does not have the possibility of assigning the maneuver, it has the opportunity to follow subjects over time. Any research that tries to explain the phenomenon of causality runs the risk of bias, however, the characteristics of the cohort studies try to avoid them. Its main features are: 1. Be observational, where the researcher only measures the presence of the maneuver, characteristic that divides subjects into exposed and unexposed. 2. Be longitudinal, which provides the opportunity to track the subject through time documenting the temporal sequence of components ocurrence. 3. The directionality in measurements, generating what we know as prolective, retrolective and retro-prolective cohort studies; the former is the one with the highest quality as a result of the measurement of the variables in real time. 4. Be a comparative study. [ABSTRACT FROM AUTHOR]

Introduction. A group of acute ps- ychosis presents a more favourable prognosis. However, some of these can develop into chronic psychotic or affective disorders. The objective is the study of diagnostic stability and prognosis in acute psychosis. Method. Five years follow-up study of acute psy- chosis in a population sample. Results. Within five years, 73.2% of the 41 patients studied received a diagnosis of chronic psychotic or affective illness, presenting further deterioration in their adaption and quality on life. Approximately 50% os cases with brief psychosis at baseline maintained that diagnosis. Although there were no differences in the diagnoses with respect to gender, women exhibited a lesser degree of degration along with better adjustment. Conclusions. The majority of patients diagnosed developed a chronic psychotic or affective illness during the five year period. The only diagnosis with a greater stability and better prognosis was that of brief psychosis disorder, especially triggered with life events. Women exhibited a better evolution and ability to adapt than men [ABSTRACT FROM AUTHOR]

Background and objective. Suicide and self-destructive behaviors are not only health problems but are also related to social and personal aspects. Public health and community action can play an important role in increasing survival among those at risk. We present the results of a program based on health education among the general population and in a specific health care setting to monitor the at risk population. Subjects and Method. The Suicide Behavior Prevention Program (SBPP) developed in the Dreta de l'Eixample district in Barcelona city included 219 patients, 148 (67.5%) of whom completed a 12-month follow-up. We selected a comparison group from a neighboring district that did not have a SBPP. This group was made up of 180 patients, 167 of whom completed the 12-month follow-up. Results. Main differences between the two groups were that patients who were enrolled in the SBPP consulted more often for suicidal thoughts than those in the comparative group (36% vs 25%), had fewer hospital admissions (6% vs 36%), presented fewer repeated suicide attempts over the 12-month follow-up (11% vs 32%) and showed longer time to repeat attempt. Conclusions. Early detection of suicidal ideation and adherence to post-suicide attempt treatment reduce the risk of recurrent suicide attempts. Further studies with longer follow up may help to reduce suicide mortality. [ABSTRACT FROM AUTHOR]

Introduction. The term acute psychosis represents a group of rapid-onset and recovery psychosis. The current diagnostic criteria are not uniform and represent a heterogeneous set of psychoses. Although their form of clinical presentation may be similar, their evolution and prognosis are very different. It is very important to detect the possible factors of chronicity in order to make an early intervention and thus to diminish the negative consequences of the disease. Methodology. We conducted a 2 year prospective study in 48 patients diagnosed with acute psychosis in their first admission. Data was collected on the evolution and follow-up of the patient in the Mental Health Unit and the sociodemographic and clinical factors of the psychotic index episode that could predict a change in the diagnosis during the two years follow-up were analyzed. Results. None of the sociodemographic or clinical variables studied could predict a change in the diagnosis, except for the presence of a control delusion during the index episode. The diagnosis of schizophreniform or not otherwise specified psychotic disorders predicts an evolution towards schizophrenia or affective psychosis while a brief or substance-induced psychotic episode has a better prognosis, with a tendency to maintain the same diagnosis in the 2 years of follow-up. Conclusion. After 2 years of follow-up, an significant number of the patients initially diagnosed of acute psychosis evolved towards a diagnosis of schizophrenia or affective psychosis in a difficult-to-predict way.

The paper by Palacios published in this journal issue, commenting our previous paper (Fernández, Álvarez, and Bravo, 2003) on the assessment of the long term outcome of children in residential child care, poses an interesting opportunity to debate not only the study methodology and research results, but also the very concept of residential care and the role of this kind of social services for child protection. The paper replies to issues raised by Palacios on: the limitations of our research, the generalizability of the results, the methodology employed, and the aims of residential care. Our reply poses the need for new methodological designs and the difficulty of finding cause-effect relationship in residential care, the use of a new terminology to overcome old concepts such as “institution” or “institutionalised”, the rationale of these programmes, and a clear set of functions for residential care. Nevertheless, the paper supports and agrees with Palacios' proposal of giving priority to developing family foster care arrangements and thus reducing residential care to specific cases [ABSTRACT FROM PUBLISHER]

INSTITUCIÓN: Clínica Universitaria Bolivariana. Medellín, Colombia INTRODUCCIÓN: En la embriogénesis genitourinaria el pronefros y mesonefros preceden al desarrollo del metanefros. Entre las semanas 9 y 12, la yema uretral y el blastema nefrótico interactúan para originar el metanefros. El riñón y el uréter se desarrollan a partir del mesodermo intermedio. La Displasia Renal Multiquística es la forma de displasia renal más grave, y más frecuente en la infancia. Hay un reemplazo del tejido renal por múltiples quistes no comunicantes unidos por tejido conectivo. La incidencia es de 1:4300 nacidos vivos, y el 94.1% de los casos son detectados por ultrasonografía antenatal. La función renal es ausente o muy escasa. En un 20-50% de los casos hay alteración contralateral, siendo lo más frecuente el reflujo vesico-ureteral. Los hallazgos ultrasonográficos muestran una masa de quistes de diverso tamaño, no comunicantes entre sí, pudiéndose observar entre los quistes un escaso estroma fibroso. La arteria renal está ausente o hipoplásica. Se deben buscar anomalías en el riñón contralateral y extrarrenales que nos permiten evaluar el pronóstico, el cual es bueno si la afectación es unilateral. En la mayoría de casos la historia natural es la involución en los primeros cinco años de vida. La incidencia de complicaciones tales como hipertensión arterial, infección o degeneración tumoral es muy baja. Por lo tanto, el manejo postnatal adecuado y seguimiento ecográfico cada 3-6 meses durante el primer año, a los 2, 5 y 10 años es importante para la evolución de la patología y detección de complicaciones futuras. MATERIALES Y MÉTODOS: Revisión de la literatura, reporte de caso. RESULTADOS: Primigestante de 30 años, G1P1, O +, sin patología de base, embarazo de 31+6 semanas; en ecografía III nivel refieren riñón derecho aumentado de tamaño, ecogénico, imágenes anecoicas, bordes bien definidos no confluentes compatibles con quistes de 21*20mm, que no sobrepasan la línea media y permaneció estable durante el seguimiento prenatal sin alteración del riñón contralateral. A las 38+6 semanas, se atiende parto intervenido sin complicaciones, bebe sexo femenino, peso 3660 g. Ecografía postnatal: riñón derecho, aumentado de tamaño sin diferenciación cortico-medular de aspecto multiquístico, riñón izquierdo normal. Valorada por nefrología, ordena gammagrafía DMSA sin compromiso renal izquierdo, control a los 4 meses de vida con CUMC, control mensual el primer año de vida y tratamiento profiláctico. CONCLUSIÓN: La Displasia Renal Multiquística es la alteración quística más frecuente en la infancia, donde es importante la realización del diagnóstico prenatal y poder determinar si el compromiso es uni o bilateral. En el caso del compromiso unilateral es esencial realizar un seguimiento al riñón contralateral que nos ayudan a evaluar el pronóstico. Sin embargo, en esta patología se realizará un diagnóstico confirmatorio postnatal, para así determinar un seguimiento periódico y prevenir o detectar tempranamente las complicaciones.
