Approach to cardiology residents clinical aptitude evaluation. Multicenter design.

INTRODUCTION: To the best of our knowledge, the research herein presented is the first multicenter study in Mexico to analyze the development of clinical aptitude in medical units that train cardiologists. OBJECTIVE: To determine the degree of development of clinical aptitude in cardiology residents at three High Specialty Medical Units. METHODS: Multicenter, cross-sectional design. All students of the 2019-2020 academic year were included in the study. An instrument was constructed that evaluated clinical aptitude based on eight indicators and 170 items; conceptual/content validity and reliability were assessed by five cardiologists with teaching and educational research experience. RESULTS: By indicator and year of residence, significant statistical differences were observed in the CMN20Nov academic site. At HCSXXI and INCICh, statistically significant differences were observed in one of eight indicators. Differences between R1 residents (n = 41) of all three academic sites were estimated by indicator, with statistical significance being recorded in three of eight indicators. Between R2 (n = 35) and between R3 residents (n = 43), the result was similar. CONCLUSIONS: The degree of clinical aptitude development can be considered intermediate in all three academic sites, probably because the instrument explored problematized clinical situations that required for the residents to critically reflect on their clinical experience.

INTRODUCCIÓN: Hasta donde se tiene conocimiento, la investigación que se presenta constituye el primer trabajo multicéntrico en México que estudia el desarrollo de la aptitud clínica en unidades formadoras de cardiólogos. OBJETIVO: Determinar el grado de desarrollo de la aptitud clínica en residentes de cardiología en tres unidades médicas de alta especialidad. MÉTODOS: Diseño transversal multicéntrico. Se analizaron todos los estudiantes del ciclo académico 2019-2020. Se construyó un instrumento que evaluó la aptitud clínica a partir de ocho indicadores y 170 ítems; la validez conceptual/de contenido y la confiabilidad fueron valoradas por cinco cardiólogos con experiencia docente y en investigación educativa. RESULTADOS: Por indicador y año de residencia se observaron diferencias estadísticas significativas en la sede CMN20Nov; en HCSXXI e INCICh se observaron diferencias estadísticamente significativas en uno de ocho indicadores. Se estimaron diferencias entre residentes R1 (n = 41) de las tres sedes por indicador, con significación estadística en tres de ocho indicadores. El resultado fue semejante al comparar R2 (n = 35) y R3 (n = 43). CONCLUSIONES: El grado de desarrollo de la aptitud clínica se puede considerar medio en las tres sedes académicas, probablemente debido a que el instrumento exploró situaciones clínicas problematizadas que exigieron del residente la reflexión crítica de su experiencia clínica.

Development and Validation of a New Scoring Tool to Evaluate the Clinical Evolution of Adult Patients with Nonsegmental Vitiligo.

BACKGROUND: Vitiligo has an unpredictable course and a variable response to treatment. Furthermore, the improvement of some vitiligo lesions cannot be considered a guarantee of a similar response to the other lesions. Instruments for patient-reported outcome measures (PROM) can be an alternative to measure complex constructions such as clinical evolution. OBJECTIVE: The aim of this study was to validate a PROM that allows to measure the clinical evolution of patients with nonsegmental vitiligo in a simple but standardized way that serves to gather information for a better understanding of the disease. METHODS: The instrument was created through expert consensus and patient participation. For the validation study, a prospective cohort design was performed. The body surface area affected was measured with the Vitiligo Extension Score (VES), the extension, the stage, and the spread by the evaluation of the Vitiligo European Task Force assessment (VETFa). Reliability was determined with test-retest, construct validity through hypothesis testing, discriminative capacity with extreme groups, and response capacity by comparing initial and final measurements. RESULTS: Eighteen semi-structured interviews and 7 cognitive interviews were conducted, and 4 dermatologists were consulted. The instrument Clinical Evolution-Vitiligo (CV-6) was answered by 119 patients with a minimum of primary schooling. A wide range was observed in the affected body surface; incident and prevalent cases were included. The average time to answer the CV-6 was 3.08 ± 0.58 min. In the test-retest (n = 53), an intraclass correlation coefficient was obtained: 0.896 (95% CI 0.82-0.94; p < 0.001). In extreme groups, the mean score was 2 (2-3) and 5 (4-6); p < 0.001. The initial CV-6 score was different from the final one and the change was verified with VES and VETFa (p < 0.05, n = 92). CONCLUSIONS: The CV-6 instrument allows patient collaboration, it is simple and brief, and it makes it easier for the doctor to focus attention on injuries that present changes at the time of medical consultation.

[Usefulness of a clinical questionnaire for screening osteopenia and osteoporosis in post-menopausal women]. / Utilidad de un cuestionario clínico en la detección de osteopenia y osteoporosis en la posmenopausia.

BACKGROUND: The prevalence of osteoporosis in post-menopausal women (PMW) is 30 %, and bone densitometry (BD) is the gold standard. This is not recommended as a screening test because of its cost. Instead, the SCORE index (Simple Calculated Osteoporosis Risk Estimation) is proposed. The objective is to determine the sensitivity and specificity of this test in the population and the optimization of BD. METHODS: The SCORE Index is a pre-screening questionnaire; it was used in PMW to compare with BD, registering the total score of the questionnaire, densitometry diagnosis, the fracture risk and the site of osteoporosis. The sensitivity and specificity of SCORE Index and chi(2) of Mantel-Hanszel were calculated. RESULTS: We studied 201 patients, mean age 55.70 years. Osteoporosis was recognized in 22.8 %, osteopenia in 68.3 % and 8.9 % was normal. The sensitivity of the SCORE index was 87 % (95 % CI = 77-97) and specificity was 34.6 % (95 % CI = 27-42) with p = 0.000. A positive probability quotient of 1.33 (95 % CI = 1.1-1.7). CONCLUSIONS: Osteoporosis is a frequent disease in PMW. It is mandatory to have cheap and easy-tools which can detect osteoporosis cases.

Metahemoglobinemia congénita. Reporte de caso / Congenital Methemoglobinemia. A Case Report

Resumen La metahemoglobinemia ocasionalmente causa cianosis, particularmente cuando es congénita. Debido a sus vías enzimáticas deficientes y a la disminución de la capacidad de transporte de oxígeno, para los pacientes con metahemoglobinemia congénita es importante evitar la exposición a agentes oxidantes. A continuación, presentamos un paciente pediátrico con metahemoglobinemia congénita no diagnosticada preoperatoriamente que fue sometido a cateterismo con diagnóstico probable de hipertensión pulmonar bajo anestesia general. El paciente pediátrico era un niño de 10 años que presentaba una lectura de oximetría de pulso (SpO2) 92% antes de la inducción de la anestesia. La metahemoglobinemia se sospechó intraoperatoriamente por primera vez debido a un desajuste de la SpO2 de la oximetría de pulso digital y la SaO2 (saturación arterial de oxígeno), y luego se confirmó mediante múltiples longitudes de onda con la CO-oximetría. Se discuten la fisiopatología, etiología, manifestaciones clínicas, consideraciones anestésicas y opciones de tratamiento de la metahemoglobinemia.

Abstract Methemoglobinemia occasionally causes cyanosis particularly in congenital methemoglobinemia. Avoidance of exposure to oxidizing agents is important for patients with congenital methemoglobinemia because of their deficient enzymatic pathways and decreased oxygen-carrying capacity. Here, we present a pediatric patient with preoperatively undiagnosed congenital methemoglobinemia who underwent catheterization with probably diagnosis of pulmonar hypertension under general anesthesia. The pediatric patient was a 10-year-old who displayed a low pulse oximetry reading of 92% prior to induction of anesthesia. Methemoglobinemia was first suspected intraoperatively because of a mismatch of SpO2 of finger pulse oximetry and SaO2 of arterial blood, and was later confirmed by multiplewavelength CO-oximetry. The pathophysiology, etiology, clinical manifestations, anesthetic considerations, and treatment options of methemoglobinemia are discussed.

[Characterizing the prescription of non-steroidal anti-inflammatory drugs among the elderly]. / Características de la prescripcion de analgésicos antiinflamatorios no esteroideos en adultos mayores.

OBJECTIVE: Determine prescription characteristics of non-steroidal anti-inflammatory drugs among the elderly attending primary medical care. MATERIAL AND METHODS: Setting, Family Health Unit 52, Mexican Institute of Social Security. DESIGN: Prospective, cross-sectional, descriptive, with randomized sampling. PARTICIPANTS: 400 patients; aged 60 and older, male and female, without cognitive impairment. Those without clinical records were excluded. Every patient was interviewed and examined and their clinical record and prescription were assesed. RESULTS: NSAIDs were prescribed in 312 patients (78% 95% CI 74-82), one type of NSAIDs was prescribed in 188 (60% 95% CI 55-65), two types in 117 (38% 95% CI 33-43) and three types in 7 (2% 95% CI 0.0-4). Of the 443 prescriptions, Acetylsalicylic acid was prescribed in 200 cases (45% 95% CI 40-50) and Naproxen in 100 (23% IC 95% 19-26). Reasons for prescribing included cardiovascularprophylaxis in 46% (IC 95% 7-13)pain management in 40% (95% CI 31-49), anti-inflammatory cases 4% (95% CI 2-6), and non-specified in 10% of cases (95% CI 7-13). Treatment duration was not specified for 253 patients (81% 95% CI 77-85). We noted drug-drug interaction in 228 cases (73% 95% CI 67-77) and a potential drug-disease interaction in 247 (79% 95% CI 77-81). The gastro-esophageal prescription was not more frequent among patients taking NSAIDs compared with non-users OR = 1 (95% CI 0.53-1.75; p = 0.89). CONCLUSIONS: NSAIDs prescription prevalence is high: although diagnoses do not justify their use and gastro-esophageal protection is often not sufficient. Prostaglandins inhibitors are favored without taking into account drug-disease interaction.

[Frequency of gastroesophageal reflux disease in elderly patients attending a family medicine clinic]. / Frecuencia de síntomas de ERGE en adultos mayores que acuden a una unidad de medicina familiar.

OBJECTIVES: To ascertain the prevalence of gastroesophageal reflux disease (GERD) in elderly people attending to family medicine clinics. MATERIAL AND METHODS: the study was conducted by using a prospective design in which participants were randomly selected from a family medicine clinic located in Mexico City. The study was run from August to September 2003, and included patients aged sixty years or older, regardless of gender. They should not have cognitive damage, which was ascertained by the Folstein Mini Mental State Examination. Those patients that did not accept to participate and those having incomplete or illegible medical records were excluded. The socio-demographic characteristics test and Carlsson-Dent test were applied. The information about diagnosis, drugs prescriptions, and pharmacological and no pharmacological gastroesophageal protection was obtained from the medical charts and prescriptions. RESULTS: 400 elderly patients were evaluated by using the Carlsson-Dent test. GERD prevalence was 25% (CI 95% 21-29) the average age of patients with and without GERD was 68 +/- 7 years and 70 +/- 7 years respectively (p = .002). Women suffered GERD more frequently than men (p = 0.001). GERD diagnosis was not found in any of the reviewed medical charts. Antacids, histamine-2 receptor antagonists (H2 As) and prokinetics were prescribed in 39% (CI 95% 34-44) of patients with GERD and in 18% (CI 95% 15-21) without GERD. CONCLUSIONS: Elderly patients attending to primary care facilities often have GERD symptoms, but they are not properly diagnosed or followed up. The Carlsson-Dent questionnaire is an alternative to identify GERD patients.

[Elaboration and validation of an index for preeclampsia diagnosis]. / Elaboración y validación de un indice para el diagnóstico de preeclampsia.

OBJECTIVE: To build a consistent and valid preeclampsia diagnosis index (IDP) for its Spanish acronyms. PATIENTS AND METHOD: The study was done in a Gyneco-Obstetrics Hospital and a Family Medicine Unit from March 2000 to February 2001. Fifty items were chosen from the literature, with a design to validate diagnostic tests, which were assessed by family doctors and gyneco-obstetricians in regard to their appearance and content validity. Concurrent criterion validity. Golden standard: Two gyneco-obstetricians diagnosed pre-eclampsia (hypertension and proteinuria). Simultaneously a family doctor (in an independent and blinded way) questioned, examined and recorded laboratory data of 219 preeclamptic patients and 251 non preeclamptic patients. RESULTS: Preeclampsia diagnosis index is an additive index with 21 clinical and paraclinical parameters weighted according to their individual diagnostic capacity. It has two parts: The first one with 82% (95%CI 80-84) sensitivity; 93% (95%CI 91-95) specificity; the second one with 86% (95%CI 83-89) sensitivity; 75% (95%CI 65-85) specificity. CONCLUSIONS: Preeclampsia diagnosis index is easily applied and has immediate results, which makes easier the physician's decisions.

[Depression prevalence and risk factors found in women attended by a family physician]. / Prevalencia de depresión y factores de riesgo en mujeres atendidas en medicina familiar.

OBJECTIVES: Determine the prevalence of depressive symptoms in adult woman who was attended by family physician, to explore risk factors for depression and estimate how often depression is registered as a diagnosis by the family physician. MATERIALS AND METHODS: We did a prospective, analytic, and transversal study with simple randomized sampling at a Mexico City Family Medicine Clinic from March to December 2004. The size of the study was 384 patients. It includes women from 20 to 59 years of age. We excluded women without a clinical file for at least 1 year of reliable information. The Center for Epidemiologic Studies Depression Scale (CES-D) and the Family Apgar Scale were applied. RESULTS: The survey included a total of 400 patients with the following characteristics: average age, 39 +/- 11 years; married, 74%; homemakers, 68%, and women with education level of high school or less were 79%. Prevalence of depressive symptoms was 52% (95% confidence interval [95% CI], 47-57). In women between 20 and 39 years of age, there was an association between depression and family dysfunction; the average number of healthcare appointments for the year prior to the study was significantly higher in patients 40 years old or more. CONCLUSIONS: There is a high prevalence of depressive symptoms in adult women, and depression diagnosis is frequently omitted. Depression-associated factors differ according to chronological age. In young women, family dysfunction is the main risk factor.

[Incidence of infected surgical wound and prophylaxis with cefotaxime in cesarean section]. / Incidencia de herida quirúirgica infectada y profilaxis con cefotaxima en cesárea.

BACKGROUND: Surgical wound infection after cesarean section varies from 2.5 to 16.1%, thus the utilization of antibiotic prophylaxis has increased routinely and irrationally. Despite this, we can still see cases of infections. OBJECTIVE: To determine if the antibiotic prophylaxis with cefotaxime is associated with the decreased incidence of wound infection in patients submitted to cesarean section without risk factors. PATIENTS AND METHODS: This study was carried out as a randomized clinical trial in patients submitted to cesarean section. Two groups were formed: in the first group we administered cefotaxime and the other one did not receive prophylaxis. The follow-up lasted 30 days to evaluate clinical data of infection. RESULTS: We performed 3,300 cesarean in the studied period; 1,000 patients had the inclusion criteria to participate in the study. A surgical wound infection was observed in 31 (0.96%) patients without risk factors. In 14 of these patients we administered cefotaxime, and in 17 patients we did not use prophylaxis. The highest frequency of infection was observed in the group of 24 to 30 years old, with 16 patients (51.6%). The clinical data of infection were: dehiscence in 29 patients (93.5%), pus secretion in 23 (74.2%), and fever in only 3 (9.7%) of them. The hospital stay after the infection was of five days in 75% of the cases. When the use of cefotaxime as prophylaxis was analyzed in both groups we had an odds ratio of 0.82, which was not significant. DISCUSSION: The use of cefotaxime in patients operated of cesarean does not have great transcendence since it does not reduce the infection incidence. The use of antibiotics in an irrational way implies a high cost, since the majority of the post-operation infections are not complicated, involving exclusively the skin and cellular subcutaneous tissue. Then, the cases with risk factors should be analyzed carefully for the cefotaxime administration.

[Clinical significance of the laboratory determinations in preeclamptic patients]. / Significado clínico de los resultados de laboratorio en las pacientes preeclámpticas.

OBJECTIVE: To determine the clinical significance and optimal cutting points of laboratory tests more frequently used in patients with pre-eclampsia of recent diagnosis. MATERIALS AND METHODS: We made an analytic cross-sectional study for evaluation of diagnostic test. Non probabilistic sampling. Sample size 400 patients. We used the American College of Obstetricians and Gynecologists criteria as gold standard. Laboratory personnel was blinded to the clinical classification of the patients. RESULTS: We studied 192 patients without pre-eclampsia, 63 with mild and 153 with severe pre-eclampsia. Hematocrits, prothrombin time, partial thromboplastin time, aspartate aminotransferase, alanine aminotransferase and bilirubins did not show significative differences among groups. Platelets counting showed low sensitivity. Lactic dehydrogenase showed 71% sensitivity (65-85 CI95%), specificity 74% (68-80 CI95%) positive likelihood ratio 2.7 and negative 0.4. Uric acid showed sensitivity of 75% (69-81 CI95%) specificity 79% (73-85 CI95%) positive likelihood ratio of 3.5 and negative of 0.3. Seric creatinine with sensitivity of 81% (76-86 CI95%) specificity of 60% (53-67 CI95%) positive likelihood ratio of 2 and negative of 0.3. CONCLUSIONS: Seric uric acid, seric creatinine and lactic dehydrogenase are useful for diagnosis and severity classification of pre-eclampsia. Platelets counting is not useful for diagnosis but is useful for severity classification. In patients with thrombocytopenia prothrombin time is useful for severity classification.

[Usefulness of establishing diagnosis and severity of the most frequent signs and symptoms in preeclamptic patients]. / Utilidad para establecer diagnóstico y severidad de los síntomas y signos más frecuentes en la paciente preeclámptica.

OBJECTIVE: Our aim was to determine that signs and symptoms are tools in establishing diagnosis and severity of preeclampsia. MATERIALS AND METHODS: Our study design was prolective, comparative, cross-sectional for evaluation of diagnosis. Our sample included 408 patients. The study employed classification criteria of the American College of Obstetricians and Gynecologists. One blinded family physician interrogated and examined each patient. The sample included patients with recent diagnosis and without treatment. Patients with HELLP syndrome, eclampsia, and those in Intensive Care were excluded. Clinical signs evaluated included headache, Phosphenes, acuphenes, tinnitus, vomiting, epigastric pain, right hypochondrium pain, ecchymosis, hematomas,and hyperreactive reflexes. RESULTS: A total of 192 patients without preeclampsia, 63 with mild, and 153 with severe preeclampsia were included. Clinical manifestations were absent in 60, 21 and 8% respectively of patients in each group. Presence of three or more signs or symptoms had sensitivity of 60% (CI95% 53-67), specificity of 84% (CI95% 79-89), and positive likelihood ratio of 3.8 and negative, 0.48. Most usefulness data for diagnosis of preeclampsia are hyperreactive reflexes, phosphenes, acuphenes, right hypochondrium pain, and epigastric pain. CONCLUSIONS: The symptoms and signs taken alone are tools for evaluation of severity but not for detection of preeclampsia. There is necessary to develop new way for it's diagnosis during prenatal care.

[Clinical practice guideline. Drug prescription in elderly]. / Guía de práctica clínica. Prescripción farmacológica en el adulto mayor.

The process of prescribing a medication is complex and includes: deciding whether it is indicated, choosing the best option, determining the dose and the appropriate management scheme to the physiological condition of the patient, and monitoring effectiveness and toxicity. We have to inform patients about the expected side effects and indications for requesting a consultation. Specific clinical questions were designed based on the acronym PICOST. The search was made in the specific websites of clinical practice guidelines, was limited to the population of older adults, in English or Spanish. We used 10 related clinical practice guidelines, eight systematic reviews and five meta-analyses. Finally, we made a search of original articles or clinical reviews for specific topics. The development and validation of clinical practice guidelines for "rational drug prescriptions in the elderly" is intended to promote an improvement in the quality of prescription through the prevention and detection of inappropriate prescribing in the elderly and, as a result of this, a decrease in the adverse events by drugs, deterioration of health of patients and expenditure of resources.

El proceso de prescribir un medicamento incluye decidir si está indicado, elegir el mejor, determinar una dosis y un esquema de administración adecuados a la condición fisiológica del paciente, el seguimiento de la eficacia y toxicidad. Debe informarse a los pacientes sobre los efectos secundarios esperados y las indicaciones para solicitar la consulta. Para la elaboración de esta guía se formularon preguntas clínicas específicas, con base en el acrónimo PICOST. La búsqueda se realizó en los sitios web específicos de guías de práctica clínica, en inglés o español, y se limitó a la población de adultos mayores. Se usaron 10 guías de práctica clínica relacionadas, ocho revisiones sistemáticas y cinco metaanálisis. Por último, se realizó una búsqueda de artículos originales o revisiones clínicas para aspectos específicos. La elaboración y validación de una guía de práctica clínica para "prescripción farmacológica razonada en el adulto mayor" tiene el propósito de promover una mejora en la calidad de la prescripción médica, mediante la prevención y detección de la prescripción inapropiada en el anciano y como resultado de esto disminuir los eventos adversos originados por fármacos, el deterioro de la salud de los pacientes y el gasto no justificado de los recursos.

Características de la prescripcion de analgésicos antiinflamatorios no esteroideos en adultos mayores / Characterizing the prescription of non-steroidal anti-inflammatory drugs among the elderly

Objetivo. Determinar las características de la prescripción de AINEs en pacientes de 60 años y más. Material y métodos. El estudio se realizó en 400 pacientes entre agosto y septiembre 2003 en una Unidad de Medicina Familiar (UMF), con base en un diseño prospectivo, transversal analítico y un muestreo aleatorio simple. Los criterios de inclusión fueron: tener 60 años o más, ser de ambos sexos sin deterioro cognitivo. Se excluyeron los que no contaban con información confiable en su expediente. Se interrogaron y exploraron a los pacientes, revisando sus expedientes y recetas. Resultados. Se prescribió AINEs a 312 de los 400 pacientes incluidos en el estudio (78% IC al 95% 74-82) de los cuales a 188 (60% IC al 95% 55-65) se recetó solamente un AINE, a 117 (38% IC al 95% 33- 43) dos y a 7 (2% IC al 95% 0.0-4) tres. El total de prescripciones fue 443. Los tipos más frecuentemente prescritos fueron el ácido acetil salicílico en 200 prescripciones (45% IC al 95% 40-50) y el naproxeno en 100 (23% IC al 95%19- 26). El ácido acetil salicílico fue recetado principalmente para profilaxis cardiovascular, mientras que el naproxeno lo fue como analgésico. La duración del tratamiento no estaba especificado en 253 pacientes (81% IC al 95% 77-85). En 228 de ellos (73% IC al 95% 68-77) se presentó interacción potencial fármaco–fármaco y en 247 (79% IC al 95% 77-81) interacción potencial fármacoenfermedad. La prescripción de una protección farmacológica gastroesofágica no se relacionó con la prescripción de AINEs (OR = 1; IC al 95% 0.53-1.75; p = 0.89). Conclusiones. La prescripción de AINEs a adultos mayores es muy frecuente; se prefiere el naproxeno como analgésico, el cual no se acompaña de protección gastroesofágica. La probabilidad de interacciones fármaco-fármaco y fármaco-enfermedad es alta.

OBJECTIVE: Determine prescription characteristics of non-steroidal anti-inflammatory drugs among the elderly attending primary medical care. MATERIAL AND METHODS: Setting, Family Health Unit 52, Mexican Institute of Social Security. DESIGN: Prospective, cross-sectional, descriptive, with randomized sampling. PARTICIPANTS: 400 patients; aged 60 and older, male and female, without cognitive impairment. Those without clinical records were excluded. Every patient was interviewed and examined and their clinical record and prescription were assesed. RESULTS: NSAIDs were prescribed in 312 patients (78% 95% CI 74-82), one type of NSAIDs was prescribed in 188 (60% 95% CI 55-65), two types in 117 (38% 95% CI 33-43) and three types in 7 (2% 95% CI 0.0-4). Of the 443 prescriptions, Acetylsalicylic acid was prescribed in 200 cases (45% 95% CI 40-50) and Naproxen in 100 (23% IC 95% 19-26). Reasons for prescribing included cardiovascularprophylaxis in 46% (IC 95% 7-13)pain management in 40% (95% CI 31-49), anti-inflammatory cases 4% (95% CI 2-6), and non-specified in 10% of cases (95% CI 7-13). Treatment duration was not specified for 253 patients (81% 95% CI 77-85). We noted drug-drug interaction in 228 cases (73% 95% CI 67-77) and a potential drug-disease interaction in 247 (79% 95% CI 77-81). The gastro-esophageal prescription was not more frequent among patients taking NSAIDs compared with non-users OR = 1 (95% CI 0.53-1.75; p = 0.89). CONCLUSIONS: NSAIDs prescription prevalence is high: although diagnoses do not justify their use and gastro-esophageal protection is often not sufficient. Prostaglandins inhibitors are favored without taking into account drug-disease interaction.

Utilidad para establecer diagnóstico y severidad de los síntomas y signos más frecuentes en la paciente preeclámptica / Usefulness of Establishing Diagnosis and Severity of the Most Frequent Signs and Synptoms in Preeclamptic Patients

Objetivo: determinar qué síntomas y signos son más útiles para establecer el diagnóstico y la gravedad de la preeclampsia. Material y métodos: estudio analítico, transversal comparativo prolectivo para evaluar una prueba diagnóstica. Muestreo no probabilístico. Tamaño de muestra 408 pacientes. Se usaron los criterios de clasificación del American College of Obstetricians and Gynecologists. Un médico familiar en forma ciega e independiente interrogó y exploró a cada paciente. Se incluyeron pacientes de reciente diagnóstico y sin tratamiento. Se excluyeron pacientes con síndrome Hellp, eclampsia y de terapia intensiva. Se evaluó: cefalea, acúfenos, fosfenos, tinnitus, vómito, dolor epigástrico, dolor en hipocondrio derecho, disuria, polaquiuria y tenesmo vesical, equimosis, hematomas e hiperreflexia Resultados: 192 pacientes sin preeclampsia, 63 con preeclampsia leve y 153 con preeclampsia severa. Fueron asintomáticas 60, 21 y 8% respectivamente. La presencia de 3 ó más síntomas o signos tiene sensibilidad de 60% (IC95% 53-67) especificidad de 84% (IC95% 79-89) cociente de probabilidad positivo de 3.8 y negativo de 0.48. Para evaluar gravedad son útiles hiperreflexia, fosfenos, acúfenos, dolor en hipocondrio derecho o epigastrio Conclusiones: existe una proporción de pacientes preeclámpticas sin manifestaciones clínicas (29%); los síntomas y signos descritos son útiles para evaluar gravedad pero no para diagnóstico de preeclampsia.
