Cultural adaptation and validation of the COPCORD questionnaire for the detection of rheumatic diseases in the indigenous Misak population

Introduction: The objective was to adapt and valídate in a culturally sensitive way the methodology of the community-oriented programme for the control of rheumatic diseases (COPCORD) in the indigenous Misak community of Colombia. Material and methods: A culturally sensitive validation of the COPCORD questionnaire in Spanish was carried out, translating into the nam trik wam language used by the Misak community of Guambia town. It was adapted to the context of this population and later a back-translation to Spanish was carried out. Finally, it was validated applying the survey with the support of bilingual translators. Participants with pain, stiffness or swelling in any joint in the previous 7 days and/or at any time in life were evaluated by physicians and physiotherapists and were then, upon confirming the diagnosis of a musculoskeletal disorder, subsequently examined by a rheumatologist. Results: In this population (n = 106), 58.5% were women with an average age of 45.5 years. In the last 7 days, 51 subjects (48.1%) reported having musculoskeletal pain and 7 (44.3%) reported pain at some time in their life. Of those who received treatment, 53.1% reported using traditional medicine, 34.4% homeopathic treatment, and 25% allopathic treatment. The COPCORD Misak demonstrated an adequate capacity to detect musculoskeletal disorders, with a sensitivity of 63.3% and a specificity of 80.3%, with a positive likelihood ratio of 3.2, and area under the curve of.71. Conclusion: The COPCORD methodology is a valid screening tool to detect musculoskeletal disorders in the Misak community.

Introducción: El objetivo fue adaptar y validar, de forma culturalmente sensible, la metodología del Programa orientado a la comunidad para el control de enfermedades reumáticas (COPCORD) en la comunidad indígena misak de Colombia. Material y métodos: Se realizó una validación culturalmente sensible del cuestionario Copcord en español, que se tradujo al nam trik wam, lengua usada por el pueblo misak del resguardo de Guambia. El cuestionario se adecuó al contexto de esta población y posteriormente se llevó a cabo una retrotraducción al español. Por último, se validó aplicando la encuesta con el apoyo de traductores bilingües. Los participantes con dolor, rigidez o hinchazón en cualquier articulación en los siete días previos, o en cualquier momento de la vida, fueron evaluados por médicos y fisioterapeutas. Al confirmarse el diagnóstico de una enfermedad musculoesquelética los participantes eran examinados por un reumatólogo. Resultados: De la población estudiada (n = 106) el 58,5% fueron mujeres, con una edad promedio de 45,4 arios. En los últimos siete días, 51 sujetos (48,1%) informaron tener dolor musculoesquelético y siete (44,3%) refirieron dolor en algún momento de su vida. Quienes recibieron tratamiento reportaron el uso de medicamentos tradicionales en un 53,1% de los casos, homeopáticos en el 34,4% y alopáticos en el 25%. El cuestionario COPCORD Misak demostró una adecuada capacidad para detectar los trastornos musculoesqueléticos, con una sensibilidad del 63,3%, una especificidad del 80,3%, una razón de verosimilitud positiva de 3,2 y un área bajo la curva de 0,71. Conclusión: La metodología COPCORD es una herramienta válida de cribado de enfermedades musculoesqueléticas en el pueblo misak.

Relación entre el uso de glucocorticoides y el daño crónico en Lupus Eritematoso Sistémico: una asociación precoz y nociva. Estudio exploratorio / Glucocorticoids related damage in Systemic Lupus Erythematosus: an early and harmful association. An exploratory analysis / Relação entre o uso de glicocorticóides e dano crônico no Lupus Eritematoso Sistêmico: uma associação precoce e prejudicial. Estudo exploratório

Resumen: Introducción: La actividad inflamatoria persistente el Lupus Eritematoso Sistémico provoca daño permanente. El daño permanente puede ser atribuido a la enfermedad y/o al tratamiento, en particular los glucocorticoides. El objetivo de este trabajo fue conocer la relación entre el daño crónico y la exposición a glucocorticoides. Material y métodos: Se realizó un muestreo no probabilístico de pacientes con lupus eritematoso sistémico. Se analizaron variables demográficas, niveles de actividad, dosis prednisona iniciales y acumuladas y niveles de daño medidos por "SLICC Damage Index " en diferentes periodos de la enfermedad. El daño fue clasificado en "relacionado" y "no relacionado" con el uso de glucocorticoides. Resultados: Se analizaron 30 pacientes, todos de sexo femenino. La media de seguimiento fueron 155 (DE 127) meses. Al final del seguimiento 13/30 (43,3%) pacientes presentaron daño orgánico. Los pacientes que presentaron daño orgánico "relacionado" con glucocorticoides al final del seguimiento presentaron dosis de inicio de prednisona significativamente mayores que los que no presentaron daño 53,3 (DE 10,3) mg/día vs. 28, 3 (DE 24) mg/día, p<0,05. Dosis de inicio mayores a 30 mg/día se relacionaron con el daño al final del seguimiento, independientemente de los niveles de actividad considerados, OR 2,05 (IC 95% 1,5 - 4,0). Las dosis acumuladas de prednisona mayores a 3000 mg en el primer año se asociaron con daño relacionado con glucocorticoides al final del seguimiento (p < 0,05). Conclusiones: Existe una acumulación de daño a lo largo del tiempo relacionado con los glucocorticoides. Esta relación es precoz, esto es, las dosis de inicio pueden relacionarse con la acumulación de daño a largo plazo, particularmente considerando los dominios relacionados con glucocorticoides, independientemente del nivel de actividad considerado.

Abstract: Introduction: Persistent activity causes irreversible organ damage in Systemic Lupus Erythematosus (SLE). Permanent damage can be attributed to the disease and to the treatment, particularly glucocorticoids. We aimed to know the relationship between the presence of organ damage and the exposure to glucocorticoids (GCC). Methodology: A non-probabilistic retrospective study of patients with SLE was performed. Demographic variables, activity levels, initial, accumulated prednisone dose and damage measured by "SLICC Damage Index (SDI)" at various stages from the diagnosis of the disease, were analyzed. Damage was classified in related and not related to GCC. Results: Thirty patients were analyzed, all women. The mean follow-up was 155 (SD: 127) months. At the end of follow-up 13/30 (43.3%) patients presented organ damage. Patients who had GCC-related damage at the end of follow-up had a significantly higher mean starting dose of prednisone, 53.3 (SD: 10.3) mg/d vs. 28.3 (SD: 24) mg/d, p <0.05. The effect on damage was observed with prednisone starting dose greater than 30 mg/d, regardless of the level of activity at the onset of the disease, OR 2.05 (CI 95% 1.5 - 4.0). Cumulative doses of prednisone at one year greater than 3000 mg, were related to GCC-related damage at the end of the follow-up (p < 0.05). Conclusions: There is an accrual of damage over time associated to glucocorticoids exposure. It is highlighted that the relationship is early, that is, the starting dose will probably signify the accumulation of damage, especially in glucocorticoid-related domains, regardless of activity levels.

Resumo: Introdução: A atividade inflamatória persistente do Lúpus Eritematoso Sistêmico (LES) causa danos permanentes. Danos permanentes podem ser atribuídos a doenças e / ou tratamento, particularmente glicocorticóides. O objetivo deste trabalho foi conhecer a relação entre dano crônico e exposição a glicocorticóides. Material e métodos: Foi realizada uma amostragem não probabilística de pacientes com LES. Variáveis demográficas, níveis de atividade, doses iniciais e acumuladas de prednisona e níveis de dano medidos pelo "SLICC Damage Index (SDI)" foram analisados em diferentes períodos da doença. O dano foi classificado como "relacionado" e "não relacionado" ao uso de glicocorticóides. Resultados: 30 pacientes, todos do sexo feminino, foram analisados. O seguimento médio foi de 155 (DP 127) meses. Ao final do seguimento 13/30 (43,3%) pacientes apresentavam lesão orgânica. Os pacientes que apresentaram lesão orgânica "relacionada" aos glicocorticoides ao final do seguimento tiveram doses iniciais de prednisona significativamente maiores do que aqueles que não apresentaram lesão: 53,3 (DP 10,3) mg / dia vs. 28,3 (SD 24) mg / dia, p <0,05. Doses iniciais maiores que 30 mg / dia foram relacionadas a danos ao final do seguimento, independentemente dos níveis de atividade considerados, OR 2,05 (IC 95% 1,5 - 4,0). Doses cumulativas de prednisona maiores que 3000 mg no primeiro ano foram associadas a danos relacionados aos glicocorticoides no final do acompanhamento (p <0,05). Conclusões: Há um acúmulo de danos ao longo do tempo relacionados aos glicocorticóides. Essa relação é precoce, ou seja, as doses iniciais podem estar relacionadas ao acúmulo de danos em longo prazo, principalmente considerando os domínios relacionados aos glicocorticóides, independentemente do nível de atividade considerado.

Se plantean recomendaciones para los distintos escenarios de la práctica ortopédica: consulta externa, hospitalización, cirugía (electiva y de urgencias) y urgencias; así como recomendaciones específicas para algunas subespecialidades (cirugía de columna, cirugía de mano y ortopedia pediátrica).

In this study, we review current evidence on how to organize an orthopaedic's department during the covid-19 pandemic, how to manage patients and how to protect health personnel. We executed these search in PUBMED, Scielo, government health agencies and scientific associations databases. We selected articles based on relevance. We made recommendations for different scenarios of orthopedic practice: outpatient clinic, inpatient care, surgery (elective and emergency) and emergency department. We also made recommendatios for some orthopaedic subspecialties, including spinal surgery, hand surgery and pediatric orthopaedics.

Caso Clínico: Neurofibromatosis Tipo 1, resolución quirúrgica / Case Report: Neurofibromatos Type 1, Surgical Management

INTRODUCCIÓN: La neurofibromatosis tipo 1(NF1) descrita por primera vez por von Recklinghausen en 1884, es una enfermedad de transmisión genética autosómica dominante, causada por un espectro de mutaciones en el gen NF-1, de evolución impredecible, que afecta múltiples órganos y sistemas, como la piel y el sistema nervioso, afectando también el desarrollo infantil y al estado neurocognitivo. Representa para el médico la toma de decisiones de manejo a menudo complejas, que requieren un enfoque multidisciplinario. CASO CLÍNICO: Paciente femenino de 9 años de edad, con antecedente de neurofibromatosis tipo 1. Presenta masa en región cervical anterior, que ocupa además el hemitórax izquierdo, comprimiendo el mediastino anterior, la tráquea del lado izquierdo, el corazón, el pulmón izquierdo; la masa produce sintomatología: disnea, disfagia y dolor, por lo que se programa intervención quirúrgica para exéresis del tumor. Se realizó cervico-esternotomía- toracotomía izquierda, se extirpó masa de 12 x 7 cm, ubicada a nivel de cayado aórtico, íntimamente adherida a la columna vertebral cervico-torácica. EVOLUCIÓN: Durante el acto quirúrgico la paciente tuvo un sangrado cuantioso, proveniente de arteria colateral de carótida común izquierda, por lo que se decidió empaquetar para resolución posterior, 24 horas después se desempaquetó, logrando control del sangrado tras el procedimiento. Los resultados de anatomía patología establecieron que la masa fue un neurofibroma. El seguimiento posterior determinó mejoría de la sintomatología, sin complicaciones quirúrgicas tardías. CONCLUSIÓN: La Neurofibromatosis es una patología congénita, poco frecuente y de complejo manejo. Aunque no existe tratamiento definitivo para la neurofibromatosis tipo 1, se puede realizar un manejo integral para mejorar la calidad de vida del paciente. Los tumores pueden extirparse mediante cirugía, aunque a menudo vuelven a crecer.(au)

BACKGROUND: Neurofibromatosis type 1, first described by von Recklinghausen in 1884, is an autosomal dominant genetically transmitted disease, caused by a spectrum of mutations in the NF-1 gen, with unpredictable evolution, that affects multiple organs and systems, such as the skin and the nervous system, also affecting child development and neurocognitive functions. It often requires complex management decisions from the physician that involve a multidisciplinary approach. CASE REPORTS: 9 year old female patient with a history of type 1 neurofibromatosis. She presented with a mass located in the anterior cervical region, occupying also the left hemithorax, compressing the anterior mediastinum, the trachea from its left side, the heart, and the left lung; the mass produced symptoms: dyspnea, dysphagia and pain, so surgical excision of the mass was scheduled. A left cervical-sternotomy-thoracotomy was performed, a 12 x 7cm mass, located at aortic arch level, closely adhered to the cervical-thoracic spine, was excised. EVOLUTION: During the surgical procedure, the patient had profuse bleeding, coming form the left common carotid colateral artery, so abdominal packing was performed, for later resolution. 24 hours later, bleeding control was achieved after the surgical re-intervention. The pathology lab results established that the mass was in fact a neurofibroma. Subsequent follow-up determined symptoms improvement, without late surgical complications. CONCLUSIONS: Neurofibromatosis is a congenital infrequent, disease, with a complex treatment. Although there is no definitive treatment for type 1 neurofibromatosis, comprehensive management can be achieved to improve the patient's quality of life. Tumors can be surgically removed, although they often grow back.(au)

Immunogenicity and safety of the 4CMenB and MenACWY-CRM meningococcal vaccines administered concomitantly in infants: A phase 3b, randomized controlled trial.

BACKGROUND: Invasive meningococcal disease has its highest incidence in infants. Co-administration of serogroup B (4CMenB) and quadrivalent conjugate (MenACWY-CRM) vaccines could protect against 5 clinically-relevant meningococcal serogroups. METHODS: This phase 3b, open, multicenter study (NCT02106390), conducted in Mexico and Argentina, enrolled and randomized (1:1:1) 750 healthy infants to receive either 4CMenB co-administered with MenACWY-CRM (4CMenB/MenACWY group), 4CMenB (4CMenB group), or MenACWY-CRM alone (MenACWY group) at ages 3, 5, 7 and 13 months. Non-inferiority of immune responses of co-administration to single administration of vaccines was assessed at 1 month post-booster dose (primary objective). Immunogenicity was evaluated pre- and 1 month post-primary and booster vaccinations using human serum bactericidal assay (hSBA). Safety was assessed. RESULTS: At 1 month post-booster vaccination, between-group hSBA geometric mean titer (GMT) ratios ranged from 0.89 to 1.03 for serogroup B strains (group 4CMenB/MenACWY over 4CMenB), and from 1.05 to 2.48 for ACWY serogroups (group 4CMenB/MenACWY over MenACWY). The lower limit of the 2-sided 95% confidence intervals for all GMT ratios was >0.5; the primary objective was demonstrated. Across all groups and serogroup B strains, 68-100% and 87-100% of children had hSBA titers ≥5 at 1 month post-primary and booster vaccination, respectively. For serogroups ACWY, ≥96% (post-primary vaccination) and ≥98% (post-booster vaccination) of children in all groups had hSBA titers ≥4. Post-booster vaccination, GMTs increased ≥5.99-fold from pre-booster values for each strain/serogroup. Solicited adverse events (AEs) were more frequent in groups 4CMenB/MenACWY and 4CMenB than in MenACWY; incidence of all other AEs was similar between groups. Serious AEs were reported for 6, 13, and 11 participants in groups 4CMenB/MenACWY, 4CMenB, and MenACWY, respectively; 1 (group 4CMenB) was considered vaccine-related. CONCLUSION: Immune responses elicited by co-administration of 4CMenB and MenACWY-CRM was non-inferior to single immunization. Co-administration of vaccines was immunogenic and well tolerated in infants. ClinicalTrials.gov: NCT02106390.

Diagnostic accuracy of multiparametric magnetic resonance imaging in detecting extracapsular extension in intermediate and high - risk prostate cancer

ABSTRACT Objectives: To evaluate the diagnostic performance of preoperative multiparametric magnetic resonance imaging (mp-MRI) as a predictor of extracapsular extension (ECE) and unfavorable Gleason score (GS) in patients with intermediate and high-risk prostate cancer (PCa). Materials and Methods: Patients with clinically localized PCa who underwent radical prostatectomy (RP) and had preoperative mp-MRI between May-2011 and December-2013. Mp-MRI was evaluated according to the European Society of Urogenital Radiology MRI prostate guidelines by two different readers. Histopathological RP results were the standard reference. Results: 79 patients were included; mean age was 61 and median preoperative prostate-specific antigen (PSA) 7.0. On MRI, 28% patients had ECE evidenced in the mp-MRI, 5% seminal vesicle invasion (SVI) and 4% lymph node involvement (LNI). At RP, 39.2% had ECE, 26.6% SVI and 12.8% LNI. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of mp-MRI for ECE were 54.9%, 90.9%, 76%, 81% and 74.1% respectively; for SVI values were 19.1%, 100%, 77.3%, 100% and 76.1% respectively and for LNI 20%, 98.4%, 86.7%, 66.7% and 88.7%. Conclusions: Major surgical decisions are made with digital rectal exam (DRE) and ultrasound studies before the use of Mp-MRI. This imaging study contributes to rule out gross extraprostatic extension (ECE, SVI, LNI) without competing with pathological studies. The specificity and NPV are reasonable to decide surgical approach. A highly experienced radiology team is needed to provide accurate estimations of tumor extension and aggressiveness.

Neisseria meningitidis and Streptococcus pneumoniae as leading causes of pediatric bacterial meningitis in nine Mexican hospitals following 3 years of active surveillance.

OBJECTIVES: Meningococcal meningitis is reported as a rare condition in Mexico. There are no internationally published studies on bacterial causes of meningitis in the country based on active surveillance. This study focuses on finding the etiology of bacterial meningitis in children from nine Mexican Hospitals. METHODS: From January 2010 to February 2013, we conducted a three years of active surveillance for meningitis in nine hospitals throughout Mexico. Active surveillance started at the emergency department for every suspected case, and microbiological studies confirmed/ruled out all potentially bacterial pathogens. We diagnosed based on routine cultures from blood and cerebrospinal fluid (not polymerase chain reaction or other molecular diagnostic tests), and both pneumococcal serotyping and meningococcal serogrouping by using standard methods. RESULTS: Neisseria meningitidis was the leading cause, although 75% of cases occurred in the northwest of the country in Tijuana on the US border. Serogroup C was predominant. Streptococcus pneumoniae followed Neisseria meningitides, but was uniformly distributed throughout the country. Serotype 19A was the most incident but before universal implementation of the 13-valent pneumococcal conjugate vaccine. Other bacteria were much less common, including Enterobacteriaceae and Streptococcus agalactiae (these two affecting mostly young infants). CONCLUSIONS: Meningococcal meningitis is endemic in Tijuana, Mexico, and vaccination should be seriously considered in that region. Continuous universal vaccination with the 13-valent pneumococcal conjugate vaccine should be nationally performed, and polymerase chain reaction should be included for bacterial detection in all cultures - negative but presumably bacterial meningitis cases.

Safety and immunogenicity of a 9-valent HPV vaccine in females 12-26 years of age who previously received the quadrivalent HPV vaccine.

OBJECTIVES: To assess the safety and immunogenicity of the investigational 9-valent (6/11/16/18/31/33/45/52/58) HPV (9vHPV) vaccine in prior recipients of a 3-dose regimen of quadrivalent (6/11/16/18) HPV (qHPV) vaccine. METHODS: V503-006 was a randomized, double-blinded, safety/tolerability and immunogenicity study of the 9vHPV vaccine in females 12-26 years of age who were previously vaccinated with qHPV vaccine. Subjects were randomized in a 2:1 ratio to receive 3 doses of 9vHPV vaccine (n=618) or saline placebo (n=306) at day 1, month 2, and month 6. Systemic, injection-site and serious adverse experiences (AEs) were monitored. Serum samples were collected at day 1, month 2, and month 7. Anti-HPV 6/11/16/18/31/33/45/52/58 titers were measured using the 9-valent HPV competitive Luminex Immunoassay (cLIA). RESULTS: The frequency of injection-site AEs (days 1-5 following any vaccination) was higher in the 9vHPV vaccine group than in the placebo group (91.1% and 43.9%, respectively). The frequencies of vaccine-related systemic AEs (days 1-15 following any vaccination) were generally comparable between the 2 groups (30.6% in the 9vHPV vaccine group, and 25.9% in the placebo group). One vaccine-related serious AE was reported in each of the 9vHPV vaccine and placebo groups. Few subjects (9vHPV=0.5%; placebo=0%) discontinued due to an AE. At 4 weeks post-dose 3, over 98% of subjects in the 9vHPV vaccine group were seropositive for HPV types 31/33/45/52/58, with marked elevations in cLIA geometric mean titers (GMTs) to these HPV types. Anti-HPV 31/33/45/52/58 GMTs were lower than in subjects administered 9vHPV vaccine who had not previously received qHPV vaccine (based on cross-study analyses); the clinical significance of this difference is unknown. CONCLUSIONS: Administration of a 3-dose regimen of 9vHPV vaccine to adolescent girls and young women 12-26 years of age who are prior qHPV vaccine recipients is highly immunogenic with respect to HPV types 31/33/45/52/58 and generally well tolerated.

Open-label trial of immunogenicity and safety of a 13-valent pneumococcal conjugate vaccine in adults ≥ 50 years of age in Mexico.

This open-label multicenter clinical trial conducted in Mexico assessed the immunogenicity and safety of a 13-valent pneumococcal conjugate vaccine (PCV13) in adults ≥ 50 years of age not previously vaccinated with the 23-valent pneumococcal polysaccharide vaccine (PPSV23). The PCV13 elicited a robust immune response in this study population, as reflected by the magnitude of fold rises in functional antibody levels measured by serotype-specific opsonophagocytic activity (OPA) assays before and 1 month after vaccination. Although the prevaccination OPA geometric mean titers (GMTs) for the majority of the serotypes were significantly lower in the 50- to 64-year age group than those in the ≥ 65-year age group, the postvaccination immune responses were generally similar. The overall immune responses were higher for the majority of the serotypes in the Mexican study population than those in similar adult study populations who received the PCV13 in Europe and the United States. PCV13 was well tolerated, and there were no vaccine-related serious adverse events. In conclusion, PCV13 is safe and immunogenic when administered to adults ≥ 50 years of age in Mexico and has the potential to protect against vaccine-type pneumococcal disease. (This study has been registered at ClinicalTrials.gov under registration no. NCT01432262.).

Resilience and related factors during female Ecuadorian mid-life.

BACKGROUND: Studies reporting on resilience (capacity to overcome life adversity) and the menopausal transition are scarce. OBJECTIVE: To assess resilience and related factors in mid-aged Ecuadorian women. METHOD: This was a cross sectional study in which 904 women aged 40-59 completed the 14-item Wagnild and Young Resilience Scale (WYRS) and a general socio-demographic questionnaire containing personal and partner data. Lower total WYRS scores indicate less resilience. Internal consistency of the tool was also assessed. RESULTS: Median age of all surveyed women was 49 years. A 51.1% were postmenopausal, 43.8% lived high altitude, 43.5% were abdominally obese, 12.6% used hormone therapy and 80.8% had a partner. Internal consistency was high for the WYRS tool (Cronbach's alpha: 0.94). Multiple linear regression analysis determined that lower total WYRS scores (less resilience) correlated with high altitude residency, more severe hot flushes, sedentarism, higher abdominal circumferences and having a partner with erectile dysfunction. Contrary to this, higher WYRS scores correlated with higher parity and sexual activity. CONCLUSION: As assessed with the WYRS tool, lower resilience of this mid-aged Ecuadorian female sample was related to various female and partner lifestyle and health issues, not necessarily related per se to the ageing process. More research using the tool is warranted.

Assessment of sexual function of mid-aged Ecuadorian women with the 6-item Female Sexual Function Index.

BACKGROUND: Assessing sexuality is a difficult task, hence used tools should be straight forward and easy to use. OBJECTIVE: To assess sexual function in mid-aged Ecuadorian women. METHOD: In this cross sectional study, 904 otherwise healthy women 40-59 years completed the short 6-item Female Sexual Function Index (FSFI-6) and a general socio-demographic questionnaire containing personal/partner data. Internal consistency of the tool was also assessed. RESULTS: Median age of the whole sample was 49 years, 51.1% were postmenopausal, 43.8% lived at high altitude, 12.6% used hormone therapy (HT), 58.5% presented hot flushes, 43.5% were abdominally obese and 80.8% had a partner. Overall, 72.4% of surveyed women reported sexual activity (n=655/904) with 65% of these presenting total FSFI-6 scores equal or below 20 the calculated median (lower sexual function). A 10.2% of those having a partner were sexually inactive. Internal consistency of tool was high (Cronbach's alpha=0.91). Total FSFI-6 scores positively correlated with coital frequency and female and partner educational level and inversely with female age, waist circumference, hot flush intensity and partner age (bivariate analysis). Multiple linear regression analysis determined that lower scores (lower sexual function) were related to high altitude, history of sexual abuse, sedentarism, hot flush intensity, partner age and sexual dysfunction whereas partner educational level, coital frequency and female parity were significantly related to higher scores (better sexual function). CONCLUSION: As assessed with a consistent, short, and easy to use tool lower sexual function of this mid-aged series was related to several female and partner factors. More research with this tool is warranted.

Perceived control over menopausal hot flushes in mid-aged women.

BACKGROUND: Hot flushes (HFs) and night sweats are frequent complaints among both peri- and postmenopausal women. Perceived control of this complaint may vary from one population to another. OBJECTIVE: To assess perceived control over menopausal HFs and determinant factors among mid-aged Ecuadorian women. METHODS: In this cross-sectional study healthy women aged 40-59 years, seeking healthcare centres of eight main cities of Ecuador with more than 100,000 inhabitants, were assessed with the Menopause Rating Scale (MRS) and those presenting HFs were requested to fill out the Perceived Control Index (PCI) and a questionnaire containing socio-demographic data (female and partner). RESULTS: A total of 1154 women participated in this study of which 56% presented HFs (n = 646). According to the MRS, 29.1% and 9.1% of these HFs were graded as severe and very severe, respectively. Mean age of women presenting HFs was 49.5 +/- 5.2 years, with 51.9% having 12 years or less of education, 61.5% being postmenopausal and 47.2% living in high altitude. At the moment of the survey 13.9% were on hormone therapy, 12.8% on phytoestrogens and 7.1% on psychotropic drugs. There was a significant decreasing trend for PCI scores (total and difficulty in control items) from one menopausal stage to the next, with no differences observed for time since menopause onset. Despite this, logistic regression analysis determined that HF severity, as determined with the MRS, was the only single predictive factor related to lower HF perceived control (total PCI score <38) (OR: 1.83 CI 95% [1.15-2.90], p < 0.01). CONCLUSION: As determined with the PCI, HF severity was related to a lower perceived control among mid-aged women.

Beliefs regarding menopausal hot flushes among climacteric women as assessed with the Hot Flush Beliefs Scale.

BACKGROUND: Hot flushes (HFs) and night sweats are frequent complaints among both peri- and postmenopausal women. Beliefs regarding these complaints may vary from one population to another. OBJECTIVE: To assess HF beliefs and factors related to negative beliefs in a climacteric Hispanic population using the Hot Flush Beliefs Scale (HFBS). METHODS: A total of 1154 healthy women (40-59 years) were assessed with the Menopause Rating Scale (MRS), those presenting HFs were requested to fill out the HFBS and a questionnaire containing socio-demographic data (female and partner). RESULTS: A total of 646 presented HFs (56%) graded according to the first item of the MRS as mild (28.6%), moderate (33.2%), severe (29.1%) and very severe (9.1%). Mean age of these women was 49.5+/-5.2 years, with 51.9% having 12 or less years of education, 61.5% being postmenopausal and 47.2% living in high altitude. At the moment of the survey 13.9% were on HT, 12.8% on phytoestrogens and 7.1% on psychotropic drugs. Women strongly disagreed in more negatively oriented items of those contained in subscale one (beliefs about self in social context). Contrary to this, women strongly agreed in more negative oriented items contained in subscale two which assesses beliefs about coping with HFs. Women presenting with severe-very severe HFs displayed higher HFBS total and subscale scores indicating a more negative belief regarding HFs. Logistic regression analysis determined that HF severity was related to higher HFBS scores for the total and subscales one and two. Current smoking, higher parity, lower female education, female psychiatric consultation, time since menopause and partner unhealthiness and alcohol consumption were also related to higher HFBS scorings. Postmenopausal status and church attendance were related to lower scores. CONCLUSION: In this mid-aged Ecuadorian female series negative beliefs regarding HFs were related to the severity of HFs and individual female or partner characteristics. Data provided from clinical research using this tool, alone or in combination with other tests, is warranted.

Risk factors related to the presence and severity of hot flushes in mid-aged Ecuadorian women.

BACKGROUND: Several studies drawn from the Ecuadorian population have previously reported that more than half of mid-aged women present hot flushes, which can impair their quality of life. However up-to-date risk factors for their presence and severity have not been assessed. OBJECTIVE: To assess hot flush frequency and intensity and related risk factors among middle-aged Ecuadorian women. METHODS: In this cross-sectional study, 1154 healthy women aged 40-59 years, visiting healthcare centers of eight main cities of Ecuador with more than 100,000 inhabitants, were assessed with the first item of the Menopause Rating Scale (MRS) and a questionnaire containing female and partner socio-demographic data. RESULTS: Mean age of the entire sample was 48.8+/-5.6 years (median 48), a 48.7% had 12 or less years of schooling, 52.8% were postmenopausal, 43.6% lived at high altitude, 56.8% were married and 10% were on hormonal therapy (HT). Hot flushes accounted for 56% (n=646) of the whole sample, of which 29.1% and 9.1% were respectively graded as severe and very severe. Logistic regression determined that female sedentarism (OR: 2.42, CI 95% [1.63-3.59]), accessing a free healthcare system (OR: 1.96, CI 95% [1.30-2.96]), living at high altitude (OR: 1.82, CI 95% [1.14-2.90]) and having a partner abusing alcohol (OR: 1.92, CI 95% [1.09-3.35]) were significant risk factors related to the presence of hot flushes. The regression model also determined that among women with hot flushes (n=646), sedentarism (OR: 1.73, CI 95% [1.14-2.62]) and having a partner with erectile dysfunction (OR: 2.57, CI 95% [1.44-4.59]) were significant risk factors related to severe/very severe hot flushes whereas married status (OR: 0.53, CI 95% [0.32-0.86]), living at high altitude (OR: 0.46, CI 95% [0.26-0.78]) and partner healthiness (OR: 0.59, CI 95% [0.36-0.95]) were not. CONCLUSION: To the best of our knowledge this is the first and largest study assessing hot flushes in a mid-aged Ecuadorian population. We found that the presence and severity were not significantly related to age and hormonal status yet to other individual female/male characteristics and the demography of the studied population.

El radiólogo debe estar familiarizado con los diferentes tipos de cirugía y elementos utilizados, la valoración de los componentes y el diagnóstico de complicaciones asociadas. En general, las principales artroplastias que se realizan en nuestro medio son de hombro, codo, cadera y rodilla. En este artículo se revisan los elementos protésicos utilizados, la valoración radiológica de las artroplastias y las complicaciones derivadas de estos procedimientos.

Tumor neuroectodérmico primitivo sarcoma de Ewing del arco cigomático y espacio masticatorio. Reporte de un caso / Primitive Neuroectodermal Tumor Ewing’s Sarcoma Arising from the Cigomatic Arch and the Masticator y Space. A Case Report

El tumor neuroectodérmico primitivo periférico (PNET, por su nombre en inglés) o neuroepitelioma periférico es una neoplasia maligna de células redondas azules pequeñas derivadas de la cresta neural. Es uno de los tipos histológicos más indiferenciados dentro de los tumores malignos. Debido a que es indistinguible del sarcoma de Ewing, imaginológica e histológicamente se considera una única patología para su estudio. Puede aparecer en la infancia o, más frecuentemente, en la adolescencia. El tratamiento incluye quimioterapia, cirugía y radioterapia. Presentamos el caso clínico de una paciente de 8 años de edad con diagnóstico de sarcoma de Ewing confirmado con histopatología e inmunohistoquímica, así como una breve revisión de la literatura.

Romboencefalosinapsis: reporte de un caso / Rhomboencephalosynapsis: A Case Report

La romboencefalosinapsis es una malformación congénita de la fosa posterior, poco frecuente, que consiste en agenesia del vermis y fusión de los hemisferios cerebelosos, en la línea media. Generalmente, se asocia con otras alteraciones supratentoriales, como hidrocefalia y fusión talámica, que condicionan el pronóstico del paciente. En este artículo se presenta el caso de una paciente de 10 meses de edad con romboencefalosinapsis.
