[Time in therapeutic range and incidence of warfarin complications in a 20-year retrospective cohort]. / Tiempo en rango terapéutico e incidencia de complicaciones por warfarina en una cohorte retrospectiva de 20 años.

OBJECTIVE: To characterize the time in therapeutic range (TTR) and estimate the incidence rate of complications (PTIRc) in adults with warfarin protocol. DESIGN: Retrospective cohort based on medical records of patients older than 18years, between 1996 and 2016 and followed for at least three months. SITE: Hematology unit of a Venezuelan specialized cardiovascular center. PARTICIPANTS: Electronic health record. MAIN MEASUREMENTS: TTR and PTIRc. The variables were sex, functional illiteracy, occupation, International Normalized Ratio (INR) and follow-up time, which were analyzed with TTR and PTIRc using binomial logistic and Poisson regression models, respectively. RESULTS: 2,770 patients were followed up for a total of 1,201,380 days, 42.3% had a TTR<65% and 3.5% had INR 2.5-3.5. 61.8% had complications. PTIRc was 6.84/100 person-months (95%CI: 6.56-7.15). TTR<65% showed significant adjusted OR with functional illiteracy and INR 2.5-3.5, while for higher PTIRc a significant RR was found in the two factors mentioned, shorter follow-up time, TTR<65% and in women. CONCLUSIONS: Despite new anticoagulant treatments, warfarin is useful. As follow-up time increased, control was better and the rate of occurrence of complications decreased; however, the conditions that showed lower TTR and higher rate of occurrence of complications require a thorough review of follow-up especially in patients with functional illiteracy.

The ART-SCORE is not an effective tool for optimizing patient selection for DEB-TACE retreatment. A multicentre Spanish study.

INTRODUCTION: The appropriate selection of hepatocellular carcinoma (HCC) patients who are eligible for transarterial chemoembolization (TACE) remains a challenge. The ART score has recently been proposed as a method of identifying patients who are eligible or not for a second TACE procedure. OBJECTIVE: To assess the validity of the Assessment for Retreatment with TACE (ART) score in a cohort of patients treated with drug-eluting bead TACE (DEB-TACE). SECONDARY OBJECTIVE: to identify clinical determinants associated with overall survival (OS). METHOD: A retrospective, multicentre study conducted in Spain in patients with HCC having undergone two or more DEB-TACE procedures between January 2009 and December 2014. The clinical characteristics and OS from the day before the second DEB-TACE of patients with a high ART score (ART≥2.5) and a low ART score (ART 0-1) were compared. Risk factors for mortality were identified using Cox's proportional hazards model. RESULTS: Of the 102 patients included, 51 scored 0-1.5 and 51 scored ≥2.5. Hepatitis C was more frequent in patients scoring ≥2.5. Median OS from the day before the second DEB-TACE was 21 months (95% CI, 15-28) in the group scoring 0-1.5, and 17 months (95% CI, 10-25) in the group scoring ≥2.5 (P=0.3562). Platelet count and tumour size, but not the ART score, were independent baseline predictors of OS. CONCLUSIONS: The ART score is not suitable for guiding DEB-TACE retreatment according to Spanish clinical practice standards.

Prevalence and prognostic meaning of interstitial lung abnormalities in remote CT scans of patients with interstitial lung disease treated with antifibrotic therapy.

OBJECTIVES: To describe the prevalence and characteristics of interstitial lung abnormalities (ILA) in CT scans performed prior to the initiation of antifibrotics in a series of patients with interstitial lung disease (ILD), and to identify characteristics apparent on early CT scans that could help to predict outcomes. METHODS: We conducted a retrospective observational study. The original cohort consisted of 101 patients diagnosed with ILD and treated with antifibrotics in a tertiary hospital. Patients were included if they had a thoracic CT scan performed at least one year before initiation of therapy. They were classified radiologically in three groups: without ILA, with radiological ILA and extensive abnormalities. ILA were classified as subpleural fibrotic, subpleural non-fibrotic and non-subpleural. The initial scan and the latest CT scan performed before treatment were read for assessing progression. The relationship between CT findings of fibrosis and the radiological progression rate and mortality were analyzed. RESULTS: We included 50 patients. Only 1 (2%) had a normal CT scan, 25 (50%) had extensive alterations and 24 (48%) had radiological criteria for ILA, a median of 98.2 months before initiation of antifibrotics, of them 18 (75%) had a subpleural fibrotic pattern. Significant bronchiectasis and obvious honeycombing in the lower zones were associated with shorter survival (p = 0.04). Obvious honeycombing in the lower zones was also significantly (p < 0.05) associated with a faster progression rate. CONCLUSIONS: Fibrotic ILAs are frequent in remote scans of patients with clinically relevant ILD, long before they require antifibrotics. Findings of traction bronchiectasis and honeycombing in the earliest scans, even in asymptomatic patients, are related to mortality and progression later on.

[Analysis of reinjection periodicity in knee osteoarthritis with different types of hyaluronic acids]. / Análisis de periodicidad de reinyección en gonartrosis con distintos tipos de ácidos hialurónicos.

OBJECTIVE: To evaluate the periodicity of hyaluronic acid (HA) reinjection in patients with knee osteoarthritis. Secondary aim: To relate the degree of arthrosis with the time between infiltrations and the possible study by subgroups between the different commercial preparations. DESIGN: Retrospective observational study. MATERIALS AND METHOD: Review of medical records and X-rays of patients with knee osteoarthritis that had been treated with intra-articular HA at the Rehabilitation Service in the period between January 2017 and June 2019. VARIABLES: Socio-demographic, Laterality, Intervention Date, Degree of Arthrosis according to Kellgren and Lawrence, HA used, Time between filtrations. Statistical analysis carried out by Kaplan-Meier curves, taking into account the reinfiltration as final event, and Kruskal-Wallis test for non-parametric quantitative data. RESULTS: We analysed 110 infiltration acts in 67 patients: average age at the time of infiltration 72.12 years, 85.1% women, 59.1% right knee. 4 types of HA: 33 cases at 1%. MW: 0.9MDa (HA1), 12 at 1.5%. MW: 1.5-2MDa (HA2), 42 at 2%. MW: 1.2MDa (HA3) and 6 Hylan G-F20. MW: 6MDa (HA4). We reinfiltrated in 31 occasions (28.2%). Average of months (IC 95%) between infiltrations: HA1 6.9 (5.7-8.16), HA2 12.5 (0-35), HA3 9.3 (5.5-13.1), HA4 5 (3-6.9). In 2 cases where it was not possible to establish the type of infiltrated formulations, the mean value between reinfiltrations was 8.5 (5.6-11.4) There were no statistically significant results by relating the HA type or the degree of arthrosis with the reinfiltration time. CONCLUSIONS: In our study, we observe that the HA3 presented a longer time between infiltrations in comparison with other types, with no possibility to detect significant differences.

Clinical features of psittacosis in 46 Chinese patients.

BACKGROUND: Psittacosis is a relatively uncommon cause of community-acquired pneumonia, often leading to diagnostic difficulty. METHODS: A retrospective study was conducted on the clinical features of psittacosis patients in China. Forty-six cases of Chlamydophila psittaci infection with atypical pneumonia of varying severity in the last two years were described retrospectively. RESULTS: Fever, relative bradycardia, and other systemic upsets were the main clinical presentation. The most common radiographic abnormality was segmental or lobar shadowing or consolidation. The total white cell counts were usually normal or slightly increased. The concentration of creatine kinase, C reactive protein, and lactic dehydrogenase increased, while albumin decreased remarkably. These cases exhibited good recovery after being treated with tetracycline or quinolone antibiotics. CONCLUSION: These features may help differentiate psittacosis from other traditional bacterial pneumonia. However, they do not provide a definitive diagnosis. Psittacosis diagnosis must perform the whole-genome sequencing for Chlamydophila psittaci in respiratory, blood, or sputum specimens. Increased awareness of psittacosis can shorten diagnostic delays and improve patient outcomes.

Neurosarcoidosis: Analysis of a series of 20 patients. / Neurosarcoidosis: análisis de una serie de 20 pacientes.

INTRODUCTION: Neurosarcoidosis is a rare complication of sarcoidosis. There are small series on the condition and very few from Spain. We conducted a retrospective study of neurosarcoidosis in Virgen de la Victoria Hospital over the last 10 years. PATIENTS AND METHOD: the medical records of patients diagnosed with sarcoidosis in our setting in the last 10 years were reviewed. RESULTS: One hundred twenty patients with sarcoidosis, 20 patients with probable neurosarcoidosis: 30% at the beginning of the illness, 55% later, 15% had isolated neurosarcoidosis. Forty percent had polyneuropathy, 15% cranial neuropathy, 15% myopathy, 10% hemispheric symptoms. OTHERS: headache, myelitis, seizures, confusional syndrome. They were treated with steroids, some of them with immunosuppressive treatment. Seventy-two percent improved or were stabilized. Therefore, neurosarcoidosis prevalence in our hospital was 11%, similar to other published series, with similar features, but polyneuropathy was more frequent. Early diagnosis is very important as prognosis is favourable with treatment.

Association between chronic lymphocytic thyroiditis and papillary thyroid carcinoma: A retrospective study in surgical specimens.

INTRODUCTION: The hypothesis of an association between papillary thyroid carcinoma (PTC) and chronic lymphocytic thyroiditis (CLT) continues to generate debate. Retrospective studies suggest that there is a greater probability of diagnosing a PTC in surgical specimens with CLT; however, prospective studies suggest that there is no true increase in risk. METHODS: An analytical, cross-section measurement and retrospective study was carried out considering gender, age and diagnosis of CLT and PTC in surgical specimens. A binary logistic regression model was proposed to predict the probability of carrying out the diagnosis of PTC based on the diagnosis of CLT, gender and age. RESULTS: The study population consisted of 1136 patients, 1047 (92.2%) women and 89 (7.8%) men, with an average age of 47.5±14.3 years. The prevalence of CLT and PTC was 14.9% and 16.1% respectively. Coexistence between PTC and CLT was found in 44 patients, corresponding to 3.9% of the population. Our logistic regression model suggests that the probability of diagnosing PTC in surgical specimens of male patients under 40 years old and with CLT is 53.8%. CONCLUSIONS: We suggest that there is a greater probability of diagnosing PTC in surgical specimens with confirmatory histological data for CLT; in addition, in males under 40 years old this probability increases.

Pure Membranous Lupus Nephritis: Description of a Cohort of 150 Patients and Review of the Literature.

OBJECTIVES: The course and long-term outcome of pure membranous lupus nephritis (MLN) are little understood. The aims of this study are to evaluate the clinical features, course, outcome and prognostic indicators in pure MLN and to determine the impact of ethnicity and the type of health insurance on the course and prognosis of pure MLN. METHODS: We conducted a retrospective review of medical records of 150 patients with pure MLN from Spain and the USA. RESULTS: Mean age was 34.2±12.5 and 80% were women. Sixty-eight percent of patients had nephrotic syndrome at diagnosis. The average serum creatinine was 0.98±0.78mg/dl. Six percent of patients died and 5.3% developed end-stage renal disease (ESRD). ESRD was predicted by male sex, hypertension, dyslipidemia, high basal 24h-proteinuria, high basal serum creatinine and a low basal creatinine clearance. Age, cardiac insufficiency, peripheral artheriopathy, hemodialysis and not having received mycophenolate mofetil or antimalarials for MLN predicted death. CONCLUSIONS: Pure MLN frequently presents with nephrotic syndrome, high proteinuria and normal serum creatinine. Its prognosis is favourable in maintaining renal function although proteinuria usually persists over time. Baseline cardiovascular disease and not having a health insurance are related with poor prognosis.

Recommendations on Testing Before Outpatient Dermatologic Surgery. / Recomendaciones en la petición de pruebas preoperatorias en cirugía dermatológica ambulatoria.

INTRODUCTION: Short-duration ambulatory surgery for the removal of skin tumors under local anesthesia is increasingly common in dermatology. Preoperative assessment has traditionally targeted the identification of any unknown diseases or other health conditions that might lead to changes in plans for anesthesia or surgery. Hospitals and specialists differ greatly in the tests they order in patients about to undergo outpatient dermatologic surgery given that hardly any finding would be likely to contraindicate or lead to changes in the procedure. This study aimed to provide guidance for those ordering tests before outpatient dermatologic surgery. METHODS: In 2017 our hospital developed a protocol to standardize preoperative testing for outpatient dermatologic surgery. We designed an observational, descriptive, retrospective analysis of tests ordered for patients scheduled for such surgery before and after the protocol was applied. RESULTS: Fewer tests were ordered after the protocol was introduced. We detected no statistically significant differences in relation to type of surgery planned or postoperative complications. CONCLUSIONS: Patients about to undergo outpatient dermatologic surgery under local anesthesia who have no unusual health risks may not require preoperative testing.

Epidemiology of dermatophytoses in 31 municipalities of the province of Buenos Aires, Argentina: A 6-year study.

BACKGROUND: No reliable data are available in the province of Buenos Aires regarding the frequency of dermatophytoses and other fungal diseases. The distribution of the clinical forms and the species involved are also unknown. AIMS: To present the data collected by the laboratories participating in the Mycology Network of the province of Buenos Aires (MNPBA) from a retrospective epidemiological survey on dermatophytoses. METHODS: A descriptive and exploratory analysis was performed on the cases of dermatophytoses gathered between 2002 and 2007 by the Mycology Network of the province of Buenos Aires. RESULTS: Of the 3966 dermatophytosis cases reported by 41 laboratories in 31 municipalities, more than a half occurred in three highly populated urban municipalities. The male:female ratio was 1:1.5. The most frequent clinical form was tinea unguium, diagnosed in 904 cases (51.83%), followed by tinea capitis (19.32%), tinea corporis (15.19%), tinea pedis (6.77%), tinea cruris (3.73%), and tinea manuum (2.18%). The species involved was identified in 1368 (33.49%) cases. Trichophyton rubrum was the most common species, with a frequency of 42.03%. An association was found between urban municipalities and T. rubrum or the Trichophyton mentagrophytes complex. CONCLUSIONS: Results from the MNPBA survey provide valuable information that should enable further interventions to be designed in order to prevent and control the disease.

Hemorragias durante el primer trimestre del embarazo: revisión narrativa / Bleeding in the first trimester of pregnancy, narrative review

Resumen ANTECEDENTES: Las hemorragias durante el primer trimestre del embarazo son un problema que se atiende en la práctica clínica obstétrica diaria. Las conductas de atención suelen estar protocolizadas en casi todas las instituciones; sin embargo, la evidencia científica actual sugiere que algunas de esas conductas no tienen una evidencia sólida que las apoye. OBJETIVO: Revisar la bibliografía reciente y resumir las principales recomendaciones para la atención de casos de hemorragia en el primer trimestre del embarazo. METODOLOGÍA: Estudio retrospectivo basado en la búsqueda bibliográfica de artículos en inglés que contuvieran los términos MeSH: "First Trimester", "Hemorrhage", "Bleeding", "Ectopic Pregnancy" "Abortion", "Incomplete Abortion", "Miscarriage", "Early Pregnancy Loss", "Threatened Abortion" y "Gestational Trophoblastic Disease". Se incluyeron ensayos clínicos controlados, estudios de casos y controles, estudios de cohorte prospectivos y retrospectivos, guías de práctica clínica, protocolos, revisiones sistemáticas y metanálisis incluidos en la base de datos PubMed de 2014 a 2021. RESULTADOS: Se encontraron 54 artículos completos, de los que se descartaron 38 por duplicidad en la información, falta de pertinencia o no actualizados. Al final, solo se incluyeron 16 artículos para la revisión narrativa. CONCLUSIONES: Las hemorragias durante el primer trimestre, si bien son frecuentes no dejan de ser un reto diagnóstico por su amplio espectro de manifestaciones clínicas y causas. Siempre es necesario correlacionar la evaluación clínica completa con los hallazgos ecográficos y las concentraciones de β-hCG y descartar las causas no obstétricas del sangrado, independientemente de la sospecha diagnóstica inicial.

Abstract BACKGROUND: Hemorrhage in the first trimester of pregnancy is a problem seen in daily obstetric clinical practice. Care behaviors are usually protocolized in almost all institutions; however, current scientific evidence suggests that some of these behaviors do not have strong evidence to support them. OBJECTIVE: To review the recent literature and summarize the main recommendations for the care of cases of hemorrhage in the first trimester of pregnancy. METHODOLOGY: Retrospective study based on a literature search of English language articles containing the MeSH terms: "First Trimester", "Hemorrhage", "Bleeding", "Ectopic Pregnancy", "Abortion", "Incomplete Abortion", "Miscarriage", "Early Pregnancy Loss", "Threatened Abortion" and "Gestational Trophoblastic Disease". Controlled clinical trials, case-control studies, prospective and retrospective cohort studies, clinical practice guidelines, protocols, systematic reviews and meta-analyses included in the PubMed database from 2014 to 2021 were included. RESULTS: We found 54 complete articles, of which 38 were discarded due to duplicity in information, lack of relevance or not updated. In the end, only 16 articles were included for narrative review. CONCLUSIONS: First trimester hemorrhage, although frequent, is still a diagnostic challenge due to its wide spectrum of clinical manifestations and causes. It is always necessary to correlate the complete clinical evaluation with ultrasound findings and β-hCG concentrations and to rule out nonobstetric causes of bleeding, regardless of the initial diagnostic suspicion.

Findings from the experience with the punch technique for auditory osseointegrated implants: A retrospective single center comparative study.

OBJECTIVE: To compare the punch technique and linear incision with soft tissue reduction for the placement of auditory osseointegrated implants (AOI) and analyze results of osseointegration obtained with the punch technique as measured with the Implant Stability Quotient (ISQ). METHODS: Case review of 34 patients who received auditory osseointegrated implants between January 2010 and July 2015 and were divided into two groups according to the surgical technique: 18 with the punch technique (PT) and 16 with the linear incision technique (LI). Minimum follow-up was four months (mean: 24 months; range 4-64 months). Included in the analysis were patient profiles and records of the demographic data, surgical indications, surgical technique, implant placement, surgical time, intraoperative complications, as well as postsurgical complications (Holgers classification) and implant stability quotients (ISQ). RESULTS: Use of larger abutments was significantly greater in the PT group (PT, 10mm; LI, 6mm, p<0.001). The PT technique resulted in a shorter procedure than the LI (PT, 20min; LI, 45min, p<0.001). Holgers classification scores identified significantly fewer skin complications one week after surgery for the PT group; however, only small differences were seen between the two groups at the one- and three-month control visits. CONCLUSIONS: As shown for our cohort, the punch technique for surgical placement of AOI is faster and presents fewer immediate postoperative complications when compared to the linear incision technique. The clinical application of the ISQ is a useful, easy method to demonstrate the status of osseointegration and, thus, the stability of the device.

Asociación entre tiroiditis linfocítica crónica y carcinoma papilar de tiroides: Revisión sistemática y metaanálisis de estudios en especímenes quirúrgicos / Association between chronic lymphocityc thyroiditis and papillary thyroid carcinoma: Systematic review and meta-analysis of studieson surgical specimens

Introducción. Existen resultados inconsistentes con relación al planteamiento de la hipótesis que sugiere una mayor probabilidad de documentar un carcinoma papilar de tiroides en especímenes quirúrgicos con cambios compatibles con tiroiditis linfocítica crónica. En los metaanálisis existentes se han incluido estudios no comparables metodológicamente y no se proponen claras fuentes de sesgo, justificación para la realización del presente metaanálisis. Métodos. Se realizó una búsqueda bibliográfica en Pubmed y Embase. Fueron obtenidos estudios retrospectivos donde se comparaba la prevalencia de carcinoma papilar de tiroides en especímenes con y sin cambios por tiroiditis linfocítica crónica. La evidencia recolectada fue sintetizada estadísticamente. Resultados. Un total de 22 artículos fueron incluidos. La población estuvo conformada por 63.548 especímenes. El OR combinado fue 1,81 (IC95%: 1,51-2,21). Hubo heterogeneidad entre la distribución de las razones de oportunidad entre los estudios (I2= 91 %; p>0,00001). La forma del gráfico en embudo de los estudios incluidos en el análisis parece estar simétrica, lo que indica la ausencia del sesgo atribuible a los estudios pequeños. Conclusiones. La literatura actual sugiere que existe un mayor riesgo de documentar un carcinoma papilar de tiroides en especímenes quirúrgicos en los que se observan cambios compatibles con tiroiditis linfocítica crónica; sin embargo, existen fuentes de sesgo que no será posible controlar en estudios retrospectivos, por lo que recomendamos estudiar la hipótesis que sugiere una mayor probabilidad de diagnosticar un carcinoma papilar de tiroides en especímenes con cambios compatibles con tiroiditis linfocítica crónica mediante metodologías prospectivas

Introduction. Inconsistent results exist in the literature regarding the hypothesis statement suggesting an increased likelihood of documenting papillary thyroid carcinoma (PTC) in surgical specimens with changes compatible with chronic lymphocytic thyroiditis. Existing meta-analyses have included studies that are not methodologically comparable and do not propose clear sources of bias, thus, this is justification for the present meta-analysis. Methods. A literature search in Pubmed and Embase was performed from January 1, 1950 to December 31, 2020. Retrospective studies comparing the prevalence of papillary thyroid carcinoma in specimens with and without chronic lymphocytic thyroiditis changes were obtained. The collected evidence was statistically analyzed. Results. A total of 22 articles were included. The study population consisted of 63,548 surgical specimens. The pooled OR, based on the studies, was 1.81 (95% CI: 1.51-2.21). There was heterogeneity between the distribution of prevalence ratios and opportunity ratios across studies (I²= 91%; p>0.00001). The funnel plot shape of the studies included in the analysis appears to be symmetrical, indicating the absence of bias attributable to small studies. Conclusions. The current literature suggests that there is an increased risk of documenting papillary thyroid carcinoma in surgical specimens in which chronic lymphocytic thyroiditis-compatible changes are observed; however, there are sources of bias that will not be possible to control for in retrospective studies, so we recommend studying the hypothesis suggesting an increased likelihood of diagnosing PTC in specimens with chronic lymphocytic thyroiditis-compatible changes using prospective methodologies

Comparación de los resultados clínicos en pacientes con Hiperplasia prostática benigna con tratamiento inicial Farmacológico, no farmacológico y quirúrgico, atendidos en el Hospital Pablo Arturo Suárez de enero 2014 a diciembre 2016 / Comparison of the clinical results in patients with benign prostatic hyperplasia with initial pharmacological, non-pharmacological and surgical treatment, managed at Pablo Arturo Suárez Hospital from january 2014 to december 2016

Contexto: Al momento existen pocos datos científicos que comparen las tres modalidades de tratamiento en Hiperplasia Prostática Benigna para determinar el mejor resultado clínico, considerando que se trata de una patología cuya incidencia aumenta a medida que aumenta la esperanza de vida poblacional. Objetivo: Comparar los resultados clínicos entre el tratamiento inicial farmacológico, no farmacológico y quirúrgico, basándose en la clínica de prostatismo en pacientes con Hiperplasia Prostática Benigna durante el período de enero 2014 a diciembre 2016. Diseño: Estudio Observacional, tipo Cohorte Retrospectiva. Pacientes y Métodos: Se procedió a dividir a 399 pacientes de acuerdo a la modalidad de tratamiento recibida. Se comparó la disminución del cuadro clínico en la primera consulta postratamiento utilizando una matriz de evaluación de síntomas urinarios elaborada por los autores, basada en la escala IPSS, que estratificó a los pacientes por el grado de severidad de la sintomatología. Se utilizó el software SPSS®. Resultados: Dentro del tratamiento no farmacológico, existió una diferencia de medias de 1,67 (IC 95% 0,49 ­ 2,85, p < 0,05); para el farmacológico fue de 0,21 (IC 95% 0,92 ­ 1,34, p = 0,713) y para el quirúrgico fue de 8,23 (IC 95% 7,19 ­ 9,27, p < 0,05). Se encontraron diferencias significativas entre los tres grupos durante la fase pretratamiento, tras estratificarlos de acuerdo al grado de severidad. Post- intervención, se compararon los resultados clínicos de cada tratamiento hallando que en pacientes con síntomas leves no existieron diferencias significativas (p = 0,087), no así para pacientes con sintomatología moderada y severa en donde se encontró una diferencia estadísticamente significativa. Conclusión: En pacientes con sintomatología urinaria catalogada como moderada y severa dentro de esta muestra, el tratamiento quirúrgico disminuyó la sintomatología urinaria en mayor proporción en comparación con el tratamiento farmacológico y el no farmacológico

Background: Currently there are few scientific data comparing the three therapeutic modalities of Benign Prostatic Hyperplasia to determine the best clinical outcome, considering that it is a pathology whose incidence increases as population life expectancy arise. Objectives: To compare the clinical results between the initial pharmacological, nonpharmacological and surgical treatment, based on clinical signs of prostatism in patients with benign prostatic hyperplasia during the period between January 2014 and December 2016. Study Design: Retrospective Cohort Study. Methods: 399 patients were divided according to the modality of treatment received: nonpharmacological, pharmacological and surgical. The decrease of the symptoms was compared with the first post-treatment consultation by using a matrix of evaluation of urinary symptoms elaborated by the authors, based on SPSS International Score; this tool stratified the patients by the severity of the symptomatology. SPSS® software was used. Results: Within the non-pharmacological treatment, there was a mean difference of 1.67 (95% CI 0.49 - 2.85, p <0.05); for the pharmacological it was 0.21 (95% CI 0.92 - 1.34, p = 0.713) and for the surgical was 8.23 (95% CI 7.19 - 9.27, p <0.05). Significant differences were found between the three groups during the pretreatment phase, after stratifying them according to the degree of severity. Post-intervention, the clinical results of each treatment were compared, finding that in patients with mild symptoms there were no significant differences (p = 0.087), not so for patients with moderate and severe symptoms where a statistically significant difference was found. Conclusion: In patients with urinary symptoms classified as moderate and severe within this sample, surgical treatment decreased urinary symptomatology in greater proportion compared to pharmacological and non-pharmacological treatment

METODOLOGÍA: Serie retrospectiva de casos con registro prospectivo de 9 pacientes con una edad promedio de 7,1 ± 3,9 años con ERC y entrenamiento aeróbico. Los pacientes realizaron 24 sesiones. Se analizaron los registros pre-post de los test de marcha de 6 min (TM6) y la velocidad máxima obtenida en el Test Cardiopulmonar Incremental (VTCI). RESULTADOS: Las medias de la distancia recorrida en TM6 pre y post entrenamiento fueron de 383 ± 142,4 m y 451,7 ± 142,4 m respectivamente (p < 0,0001). Las medias de las VTCI pre y post entrenamiento fueron: 4,1 ± 1,1 km/h y 5,4 ± 1,27 km/h (p = 0,001). CONCLUSIONES: La distancia recorrida en el TM6 y la capacidad máxima de trabajo mejoraron significativamente con el entrenamiento aeróbico en estos pacientes con ERC.

INTRODUCTION: Chronic respiratory diseases (CRD) in children have increased in recent years. Respiratory Rehabilitation is one of the treatments used in this population. OBJECTIVE: To evaluate the impact of a treadmill training program over pediatric patients with CRD in the Josefina Martínez Children's Hospital at Santiago de Chile. METHODS: Retrospective cases series with prospective record of 9 patients 7.1 ± 3.9 years-old with CRD and treadmill training. The patients performed 24 sessions. The Pre-post records of the 6-minute walk test (6MW) and the maximum speed obtained in the Incremental Load Test (ILT) were analyzed. RESULTS: Averages of the distance traveled pre and post-training were 383 ± 142.4 meters and 451.7 ± 142.4 meters respectively (p < 0.0001). The average maximum speed obtained in the ILT was 4.1 ± 1.1 km/h and 5.4 ± 1.27 km/h (p = 0.001). CONCLUSION: The distance walked in the 6-minute walk test and the maximum work capacity improve significantly with treadmill training in these patients with CRD.

Subtipo Persecutorio Del Trastorno Delirante: Estudio De Series De 129 Casos / Persecutory Subtype Of Delusional Disorder. Descriptive Study Of 129 Cases

Resumen Objetivo. El objetivo de este estudio es conocer las características demográficas, factores ambientales, factores de riego psicosociales, y clínicas del subtipo persecutorio en un grupo de pacientes con trastorno delirante (TD). Metodología. Estudio epidemiológico retrospectivo sobre un Registro de Casos en el Dispensario de Psiquiatría e Higiene Mental de Córdoba sobre pacientes con TD según criterios DSM-IV-TR. Aquellos pacientes que cumplieron con los criterios de inclusión definidos constituyeron nuestra muestra final de 261 casos, de ellos 129 casos presentaban el subtipo persecutorio. Las variables sobre las que se recogió información en base a protocolos, fueron agrupadas con el orden siguiente: I. Variables de los datos sociodemográficos y generales. II. Variables de los Factores de riesgo del TD (familiares y personales). III. Variables del Cuadro Clínico y el Diagnostico del TD (Presentación, sintomatología delirante, funcionalidad y discapacidad, utilización de los recursos sanitarios, tratamiento, problemas psicosociales, evolución y curso). Resultados. La proporción hombres versus mujeres en el subtipo persecutorio fue de 1,04. Solo el 5,4% de estos pacientes tenía estudios primarios. Un 65,9%, al realizar la primera consulta psiquiátrica, se encontraba casado y el 50,4% convivían en el hogar. Un 14,7% consumió previamente alcohol y un 0,8% otras sustancias. Las ideas de referencia y de persecución se presentaron el 98,4% y en el 99,2% de los casos respectivamente. Conclusiones. Son necesarios futuros estudios prospectivos para investigar los factores de riesgo del subtipo persecutorio del TD.

Objective. The objective of this study is to investigate the demographic, environmental, psychosocial and clinical characteristics of the persecutory subtype in a group of patients with delusional disorder (DD). Methodology. Retrospective descriptive study of DD cases registered at Psychiatry and Mental Hygiene Clinic of Cordoba according to DSM-IV-TR criteria was conducted. We obtained a sample of 261 DD patients who met the inclusion criteria; of them 129 cases has persecutory subtype. Data and variables collected were divided into 4 groups: I. Socio-demographic and general data. II. DD risk factors (personal and family). III. DD clinical picture and diagnosis (presentation, symptoms, disability, use of health care resources, treatment, and evolution). Results. The proportion of males versus females of the persecutory subtype was of 1.04. Only 5.4% of patients had primary level of education. At the first visit of the psychiatry clinic, 65.9% of the patients were married and about half of them shared home. About 14.7% of patients had a past history of alcohol consumption, and only 0.8% consumed other drugs. Ideas of reference and of persecution were found in 98.4% and 99.2% respectively. Conclusions. It is necessary to conduct future prospective studies to investigate the risk factors associated with the persecutory subtype of DD.

Fracturas inestables de radio distal intra y extraarticulares: análisis comparativo de resultados a mediano plazo del tratamiento quirúrgico con placas volares / Intra- and extra-articular distal radius unstable fractures: comparative analysis of the medium-term results of volar plate surgical treatment

Introducción Comparar los resultados radiológicos y recuperación postoperatoria de la función de la muñeca a mediano plazo en las fracturas inestables extra e intra articulares de radio distal, después de la reducción abierta con abordaje palmar y osteosíntesis con placa volar. Materiales y métodos Estudio de casos y controles en 52 pacientes divididos en los grupos de fracturas extra o intra articulares de acuerdo a la clasificación AO. Las radiografías preoperatorias y postoperatorias fueron evaluadas para determinar la restauración anatómica de la longitud radial, ángulo radial e inclinación palmar del radio. Se evaluó además el resultado, seis meses después de la cirugía, del rango activo de movimiento y la fuerza de agarre, a la vez, que se hizo evaluación del puntaje de QuickDASH. Resultados La edad promedio fue 53,7±16,8 (DE) años; el 63% mujeres. Las fracturas extra articulares fueron más frecuentes en las mujeres, pero las intra articulares presentaron distribución similar por sexo (p=0.023). La fuerza de agarre de la mano operada fue 73.7% y 67.5% de la mano opuesta en las fracturas extra e intra articulares, respectivamente. El puntaje QuickDASH promedio fue 2.36 (DE 2.01) y 4.16 (DE 3.82) en fracturas extra e intra articulares respectivamente (p=0.111). Discusión Para fracturas de radio distal la reducción abierta con abordaje palmar y estabilización con placa volar ofrece resultados funcionales satisfactorios tanto para las fracturas extra articulares como para las intra articulares, con una leve, aunque esperada, ventaja en las primeras debido a su menor complejidad.

Background To examine and compare the radiological results and postoperative recovery of the medium-term wrist function in unstable extra- and intra-articular fractures of distal radius, after open reduction with a palmar approach and osteosynthesis with a volar plate. Materials and methods Retrospective case control study in 52 patients, divided into groups according to the Orthopaedic Association (AO) classification as extra- or intra-articular fractures. The pre-operative and post-operative radiographs were evaluated to determine the anatomical restoration of the radial length, radial angle, and palmar inclination of the radius. The medium-term results of the active range of motion and the grip strength, as well as the Quick DASH score, were evaluated six months after surgery. Results The mean age was 53.7±16.8 (SD) years and 63% were women. Extra-articular fractures were more frequent in women, but intra-articular fractures had a similar distribution by gender (P=.023). The grip strength of the operated hand was 73.7% and 67.5% of the opposite hand in the extra- and intra-articular fractures, respectively. The mean Quick DASH score was 2.36 (SD 2.01) and 4.16 (SD 3.82) in extra- and intra-articular fractures, respectively (P=.111). Discussion For unstable distal radius fractures, open reduction with palmar approach and volar plate stabilisation offers satisfactory functional results for both extra-articular and intra-articular fractures, with a slight, but expected, advantage in the former due to its lesser complexity.

Ureteroscopia con litotripsia para el tratamiento de la litiasis ureteral inferior: casuística del Servicio de Urología del Hospital Luis Vernaza en el período 2015 ­ 2017 / Ureteroscopy with lithotripsy for the treatment of lower ureteral lithiasis: case reports from Urology Department of the Luis Vernaza Hospital in the period 2015 - 2017

En Ecuador la litiasis renal y del uréter causan alrededor de diez mil egresos hospitalarios a nivel nacional. La endolitotomía ha tenido una transición de la litotripsia balística al láser. Objetivo Comparar los datos quirúrgicos y tasa de éxitos de ureteroscopias semirrígidas usando litotripsia balística o laser. Diseño Estudio retrospectivo Lugar y sujetos Un total de 137 pacientes con litiasis ureteral distal, atendidos en el Hospital Luis Vernaza de Guayaquil-Ecuador, entre enero 2015 y junio 2017. Mediciones principales Datos clínicos de los pacientes, ubicación y dimensión del cálculo, tiempo quirúrgico, complicaciones y tasa de éxitos. Resultados Los pacientes (39.3% hombres y 60.7% mujeres) tuvieron una edad media de 52.4 ± 2.1 años. La mayoría tuvieron cólico nefrítico (77.0%), por litiasis en uréter inferior (izquierdo [45.8%] o derecho [38.7%]) o uréter medio (izquierdo [8.9%] o derecho [6.0%]). Hasta el 90% de los casos fueron de cálculos únicos. Los pacientes fueron tratados con láser (n=50) o con litotripsia balística (n=87). En el grupo de láser, la dimensión del cálculo fue mayor (12.6 ± 1.29 vs. 11.5 ± 0.8 mm; p=0.001), el procedimiento quirúrgico tuvo más duración (66.9 ± 7.4 vs. 58.8 ± 5.3 minutos; p=0.001) y hubo más tiempo postoperatorio previo al egreso (2.22 ± 0.57 vs. 1.7 ± 0.2 días; p=0.001). La taza libre de litiasis fue similar en ambos grupos (98.0% vs. 91.9%; p=ns). Las complicaciones fueron pocas (n=14; 10.2%) y en igual frecuencia con ambas técnicas, pero hubo más casos de retropulsión del cálculo con la litrotripsia balística (n=7) que con el láser (n=1). Conclusión La endolitotomía láser tiene mayores beneficios en cuanto al tamaño del cálculo que puede ser tratado y pocos eventos de retropulsión. La litotripsia balística tuvo mejor tiempo quirúrgico y menos días de egreso postoperatorio. No obstante, la tasa de éxitos aparentemente es similar con ambas técnicas.

Infecciones helmínticas intestinales diagnosticadas en el ambulatorio urbano Los Curos, Mérida / Intestinal helminth infections diagnosed in the ambulatory urban Los Curos, Merida

Las infecciones helmínticas intestinales que afectan al hombre están íntimamente ligadas a condiciones ecológicas, humanas y/o sociales que pueden favorecer o no su persistencia. El objetivo del presente trabajo fue presentar la casuística de las infecciones helmínticas intestinales que se diagnosticaron en el Laboratorio Clínico Asistencial del Ambulatorio Urbano Tipo III Los Curos entre los años 2012 a 2015. Para tal fin se realizó una investigación retrospectiva donde se estudiaron para el período evaluado los registros del laboratorio. Los resultados evidenciaron 61,7% de individuos parasitadas, 1,9% con algún helminto (Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis, Enterobius vermicularis, Hymenolepis nana o Ancylostomideos). No se evidenció diferencia entre la presencia de helmintos y los parámetros demográficos edad o género. Se concluye que las condiciones ecoepidemiológicas de Los Curos no son lo suficientemente aptas para el mantenimiento de infecciones helmínticas intestinales.

The intestinal helminth infections that affect man are intimately linked to ecological, human and / or social conditions that may or not allow their persistence. The objective of the present study was to present the casuistry of the intestinal helminth infections that were diagnosed in the Clinical Laboratory of the Ambulatory Urban III Los Curos between the years 2012 to 2015. For that purpose, a retrospective investigation was carried out where they were studied for the period laboratory records were evaluated. The results evidenced 61.7% of parasitized individuals, 1.9% with some helminth (Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis, Enterobius vermicularis, Hymenolepis nana or Ancylostomideos). There was no difference between the presence of helminths and the demographic parameters age or sex. It is concluded that the ecoepidemiological conditions of Los Curos are not sufficiently adequate for the maintenance of intestinal helminth infections.
