Results of surgical treatment of lymph node metastases in patients with cutaneous squamous cell carcinoma of the head and neck.

INTRODUCTION: Out of all cutaneous squamous cell carcinomas originating in the head and neck (HNCSCC), 2-4% are associated with parotid or cervical lymph node metastasis. The aim of this study is to analyse the prognostic factors of patients with HNCSCC with lymph node involvement treated surgically. Additionally, we aim to compare the prognostic capacity of the classification of these patients according to the 8th edition of the TNM, and an alternative classification proposed by O'Brien et al. PATIENTS AND METHODS: Retrospective review of 65 patients with HNCSCC with lymph node metastasis treated surgically during the period 2000-2020. RESULTS: During the study period we carried out 13 neck dissections and 52 parotidectomies + neck dissection in patients with lymph node metastases from a HNCSCC. The great majority of patients (89.2%) received post-operative radiotherapy. The 5 year disease-specific survival was 69.9%, and the overall survival it was 42.8%. The classification proposed by O'Brien et al., based on the parotid or cervical location of the lymph node metastases, and the size and number of the metastatic lymph nodes, had a better prognostic capacity than the TNM classification. CONCLUSIONS: The surgical treatment of lymph node metastases in patients with HNCSCC achieved a high disease control. The classification based on the location, size and number of lymph node metastases proposed by O'Brien et al had better prognostic capacity than the TNM classification.

Instability of tear film and loss of meibomian glands in patients with acne vulgaris / Instabilidade do filme lacrimal e perda de glândulas meibomianas em pacientes com acne vulgaris

ABSTRACT Purpose: In this prospective study, we compared ocular clinical variables in patients with acne vulgaris with those of healthy controls. These variables included tear film break-up time, meibomian gland dropout rate, and anterior chamber parameters. Methods: Our sample comprised 73 eyes from 73 patients with acne vulgaris and 67 eyes from 67 healthy controls. All participants underwent a non-invasive first tear film break-up time test and the average tear film break-up time was evaluated. Meibography was used to identify any meibomian gland dropout. The parameters of the cornea and anterior chamber were measured using Scheimpflug topography imaging. Finally, the ocular surface disease index questionnaire was administered to score each participant on their subjective experience of ocular complaints. Results: The noninvasive first tear film break-up time values of the acne vulgaris Group and the control Group were 4.7 ± 2.8 and 6.4 ± 3.5 sec, respectively. There was a significant difference between the groups (p=0.016). The number of eyes with tear break-up at any time during the measurement period was also significantly higher in the acne Group (p=0.018). In the acne vulgaris Group, the mean meibomian gland dropout rates were 33.21 ± 15.5% in the upper lids and 45.4 ± 14.5% in the lower lids. In the control group, these rates were 15.7 ± 6.9% and 21 ± 9.7% respectively. Dropout was significantly higher in the acne group for both the upper and lower lids (p=0.000). Conclusion: We found impaired tear stability in patients with acne vulgaris and a high rate of meibomian gland dropout. These glands play a key role in tear stability and their dropout is likely to result in evaporative dry eye. Measurement of the variables in this study allows objective diagnosis of this condition using a non-invasive, dye-free methodology, with minimum contact.

RESUMO Objetivo: Neste estudo prospectivo, pacientes com acne vulgaris e indivíduos saudáveis do grupo controle foram comparados em relação ao tempo de ruptura do filme lacrimal, taxa de abandono de glândulas meibomianas e parâmetros da câmara anterior, usando o tempo de ruptura do filme lacrimal topográfico não invasivo, meibografia não invasiva e fotografia de Scheimpflug, respectivamente. Métodos: Setenta e três olhos de 73 pacientes com acne vulgaris e 67 olhos de 67 indivíduos saudáveis foram incluídos. Todos os participantes submetidos ao primeiro tempo de ruptura do filme lacrimal não-invasivo e ao tempo médio de ruptura do filme lacrimal não-invasivo foram avaliados pelo uso do tempo de ruptura do filme lacrimal; perda de glândulas meibomianas foram avaliadas por meibografia; os parâmetros da córnea e da câmara anterior foram medidos por fotografia de Scheimpflug; e, finalmente, as queixas oculares subjetivas foram pontuadas com o uso do questionário do Indice de doenças de superfície ocular. Resultados: Os valores do tempo de ruptura do primeiro filme lacrimal não-invasivo do Grupo com acne vulgaris e do Grupo controle foram 4,7 ± 2,8 e 6,4 ± 3,5 segundos, respectivamente, refererindo-se a uma diferença significativa entre os valores dos grupos (p=0,016). Qualitativamente, o número de olhos com ruptura lacrimal a qualquer momento durante o período de medição foi significativamente maior no grupo de pacientes. (p=0,018). No Grupo com acne vulgaris, a perda de glândulas meibomianas nas pálpebras superiores foi de 33,21 ± 15,5% e nas pálpebras inferiores foi de 45,4 ± 14,5%; por outro lado, no Grupo controle foi de 15,7 ± 6,9% e 21 ± 9,7% respectivamente; ambos os casos referem-se a uma diferença significativa entre os grupos (p=0,000). Conclusão: Encontramos estabilidade comprometida do filme lacrimal em pacientes com acne vulgaris. No entanto, o comprometimento foi de grau muito menor, em comparação com a taxa de perda das glândulas meibomianas que desempenham um papel fundamental na estabilidade do filme lacrimal. Esta condição pode ser documentada de forma objetiva - uma metodologia parcialmente sem contato, totalmente não-invasiva e livre de corantes.

O desamparo em Freud e a política como ruptura dos possíveis / Helplessness in Freud and politics as a rupture of the possible / Le délaissé chez Freud et la politique comme rupture du possible / Lo desamparo en Freud y la política como ruptura de lo posible

Este trabalho visa delinear o conceito de desamparo por meio da metapsicologia freudiana e como isso implica outra forma de pensar a política. Desse modo, o desamparo não é concebido unicamente como a vulnerabilidade do bebê ao nascer, mas, também, como a falta de respostas às excitações internas. Tal estado de desamparo é radicalizado a partir da concepção de pulsão de morte construída por Freud. A pulsão de morte gera processos de desabamentos, rupturas, desligamentos e despossessão, essenciais para a própria vida se complexificar. Nesse sentido, propomos o desamparo como afeto político central quando pensamos em transformação. A partir do desabamento de si e da abertura radical ao contato do outro, podemos experimentar outras formas de experiências, outras formas de afetação e, consequentemente, a construção de corpos políticos rumo à transformação política radical

This paper outlines the concept of helplessness through Freudian metapsychology and by doing so imply a new way of thinking about politics. Helplessness is not conceived simply as the newborn's vulnerability, but also as the lack of response to internal excitements. Such an estate is radicalized by Freud's concept of death drive, which generates processes of collapsing, ruptures, unplugging and dispossession that are essential for turning life complex. In this sense, we propose helplessness as a main political affection when referring to transformation. By the collapse of oneself and the radical opening to contact with others, one may experience other ways of experiencing and of being affected and, consequently, the construction of political bodies leading to the radical transformation of politics

Cet article présente le concept de délaissé à travers la métapsychologie freudienne et, ce faisant, lui imprime une nouvelle façon de penser la politique. Le délaissé n'est pas simplement conçu comme la vulnérabilité du nouveau-né, mais aussi comme une absence de réponse aux excitations internes. Tel état est radicalisé par le concept de pulsion de mort de Freud, qui produit des processus de glissement, de rupture, d'arrêt et de dépossession essentielles à la complexification de la vie. En ce sens, nous proposons le délaissé comme principale affection politique lorsqu'il est question de transformation. Par le glissement de soi-même et l'ouverture radicale au contact avec les autres, nous pouvons expérimenter d'autres façons de vivre et d'être affecté et, par conséquent, la construction de corps politiques vers à la transformation politique radicale

Este artículo pretende esbozar el concepto de desamparo a través de la metapsicología freudiana y cómo esto implica otra forma de pensar sobre política. De esa manera, la impotencia no solo se concibe como la vulnerabilidad del bebé al nacer, sino también debido a la falta de respuestas a las excitaciones internas. Tal estado de desamparo se radicaliza desde la concepción del impulso de muerte construido por Freud. El impulso de la muerte genera procesos de colapsos, rupturas, desconexiones y desposesión esenciales para que la vida misma se vuelva más compleja. En este sentido, proponemos lo desamparo como un afecto político central cuando pensemos en la transformación. Desde el colapso de uno mismo y la apertura radical al contacto con el otro, podemos experimentar otras formas de experiencias y otras formas de afectación y,en consecuencia, la construcción de cuerpos políticos hacia una transformación política radical

Defecto septal ventricular postinfarto: complicación devastadora / Post-infarction ventricular septal defect: a devastating complicatio

Introducción: la comunicación interventricular es la complicación mecánica más frecuente después de un infarto agudo del miocardio en especial si cursa con elevación del ST, cuya frecuencia es alrededor de 0.21%, aumentando cuando es extenso y no reperfundido en pacientes con mayor edad, si hay compromiso multivaso y sin colateralidad; es una situación devastadora de mal pronóstico. Presentación de los casos: se describen 2 casos en un hospital universitario de Bogotá posteriores a infarto agudo del miocardio con elevación del ST y sin reperfusión temprana, ambos en choque cardiogénico, el primero con evolución tórpida y mortalidad temprana y la segunda fue llevada a los 10 días a cierre transcatéter, documentándose periprocedimiento un aumento significativo del tamaño del defecto septal, con mayor inestabilidad hemodinámica y muerte posterior al cierre.

Introduction: ventricular septal communication is the most frequent mechanical complication of acute myocardial infarction (MI), especially if associated with ST-segment elevation, featuring a rate of around 0.21%, which increases in older patients with extensive defects and no reperfusion therapy. In patients with multivessel involvement and no collateral circulation; it is a catastrophic situation which carries a poor prognosis. Case reports: two patients admitted to a university hospital in Bogotá, with ST-elevation post-MI VSD, undergoing no early reperfusion, both in cardiogenic shock. The first patient had a torpid evolution and early mortality. The second patient underwent a VSD transcatheter repair 10 days after MI, determining significant periprocedural increase in the size of the septal defect, with greater hemodynamic instability and death.

Abstract Objective: To describe the prevalence of perineal laceration, based on the self-reported perception of postpartum women, and to analyze factors associated with its occurrence in Brazil. Methods: This was a cross-sectional study conducted with 23,894 postpartum women, excluding twin pregnancies, cesarean sections, and births with episiotomies, between 2011 and 2012. Prevalence ratios (PR) and 95% confidence intervals (95%CI) of association between the event and maternal, fetus/newborn, obstetric and clinical management characteristics were estimated in hierarchical Poisson regression models. Results: Out of 4,606 postpartum women, 49.5% (95%CI 46.1;42.9) self-reported perineal laceration. Being an adolescent (PR = 1.12; 95%CI 1.02;1.25), primipara (PR = 1.47; 95%CI 1.33;1.63), having had excessive gestational weight gain (PR = 1.17; 95%CI 1.07;1.29) and having undergone the Kristeller maneuver (PR = 1.18; 95%CI 1.08;1.29) increased the proportion of the outcome. Conclusion: The results found call for prenatal care and adjustments to childbirth care so as to be in accordance with current recommendations.

Resumen Objetivo: Describir la prevalencia de laceración perineal, a partir de la percepción autoinformada de puérperas, y analizar los factores asociados a su aparición en Brasil. Métodos: Estudio transversal entre 2011 y 2012, con 23.894 puérperas, excluyendo embarazos gemelares, cesáreas y partos con episiotomías.

Ser adolescente (RP = 1,12; IC95% 1,02;1,25), primípara (RP = 1,47; IC95% 1,33;1,63), ter tido ganho de peso gestacional excessivo (RP = 1,17; IC95% 1,07;1,29) e ter sido submetida à manobra de Kristeller (RP = 1,18; IC95% 1,08;1,29) elevaram a proporção do desfecho. Conclusão: Os resultados encontrados demandam atenção pré-natal e adequações na assistência ao parto conforme recomendações vigentes.

Minimally Invasive Suture Technique Pull-out to Repair the Acute Flexor Tendons in Zone II of the Hand / Técnica de sutura minimamente invasiva pull-out para reparar lesões agudas dos tendões flexores da zona II da mão

Abstract Objective: To evaluate the safety and effectiveness of a modified pull-out suture technique in patients undergoing primary repair surgery for injuries to the flexor tendons of the fingers with Total Active Motion (TAM) as the primary outcome. Method: A total of 29 patients (38 fingers) were chosen from both sexes, aged between 18 and 65 years with clean acute tendon laceration occurring within 15 days, in the Verdan's zone II of flexor tendon in the hand, when only the deep flexor tendon was sutured, either associated or not with digital nerve injury. The patients were operated on using the proposed technique and evaluated at 3, 9 and 24-weeks PO. The primary outcome was the assessment of Total Active Movement (TAM) and 3 classifications were employed: Strickland, IFSSH and Buck-Gramcko. Results: We observed a total active motion (TAM) of 209.3 °at the end of 24 weeks; 83.0% of Good and Excellent results by the Modified Strickland Classification, 93% of Excellent results by the IFSSH Classification, and 97% of Good and Excellent results using the Buck-Gramcko Classification. There were no cases of rupture, but tendon adhesion was observed in 3 fingers. Conclusion: The present suture technique proved to be safe and effective with a low rate of complications, obtaining an excellent functional result in terms of total active mobility, according to the evaluations and classifications used.

Is spleen-preserving surgery safe for abdominal trauma?

BACKGROUND: Treatment of splenic trauma is currently based on non-surgical treatment or the use of interventional radiology. The conservative surgery of the spleen in splenic trauma remains marginal. OBJECTIVE: To analyze the safety and efficacy of conservative surgical treatment in splenic trauma. METHOD: A retrospective study was performed over a 16-year period with the intention of recording the diagnostic and therapeutic attitude in a second level hospital, focusing on patients who received conservative splenic surgical treatment for splenic trauma, excluding splenectomies and non-surgical treatment. RESULTS: 110 patients presented splenic trauma. Spleen-sparing surgery was performed in 15 patients. The grades of splenic lesions were: 1 patient with grade I, 1 patient with grade II, 7 patients with grade III and 6 patients with grade IV. Surgical treatment was splenorrhaphy in 5 patients (33%), hemostatic agents and polyglycolic acid mesh in 4 (26%), partial splenectomy with placement of polyglycolic acid mesh in 3 (20%), partial splenectomy in 2 (13%), and electrocautery in 1 (6%). None of the patients initially treated with conservative surgery required posterior splenectomy and no patient died. CONCLUSION: We provide evidence supporting the usefulness and safety of conservative splenic surgery in splenic trauma, which would have its place in grades II, III and IV trauma in health centers that do not have urgent interventional radiology.

ANTECEDENTES: El tratamiento del traumatismo esplénico se basa en medidas conservadoras no quirúrgicas o en el uso de radiología intervencionista. La cirugía conservadora del bazo en el traumatismo esplénico sigue siendo inusual. OBJETIVO: El análisis de seguridad y eficacia del tratamiento quirurgico conservador en el traumatismo esplénico. MÉTODO: Se realizó un estudio retrospectivo durante un período de 16 años con la intención de registrar la actitud diagnóstica y terapéutica en un hospital de segundo nivel, enfocándose en los pacientes que recibieron tratamiento quirúrgico conservador esplénico por traumatismo esplénico, excluyendo esplenectomías y tratamientos no quirúrgicos. RESULTADOS: 110 pacientes presentaron traumatismo esplénico. La cirugía conservadora esplénica se realizó en 15 pacientes. Los grados de lesiones esplénicas fueron: 1 paciente con grado I, 1 paciente con grado II, 7 pacientes con grado III y 6 pacientes con grado IV. El tratamiento quirúrgico fue esplenorrafia en 5 pacientes (33%), agentes hemostáticos y malla de ácido poliglicólico en 4 (26%), esplenectomía parcial con colocación de malla de ácido poliglicólico en 3 (20%), esplenectomía parcial en 2 (13%) y hemostasia con electrocauterio en 1 (6%). Ninguno de los pacientes tratados inicialmente con cirugía conservadora requirió esplenectomía posterior y ningún paciente falleció. CONCLUSIONES: La cirugía conservadora esplénica puede ser útil y segura en traumatismos esplénicos, la cual tendría su lugar en traumatismos de grados II, III y IV en centros hospitalarios en los que no se cuente con radiología intervencionista urgente.

MRI is a Reliable Method for Measurement of Critical Shoulder Angle and Acromial Index / A ressonância magnética é um método confiável para medida do ângulo crítico do ombro e do índice acromial

Abstract Objective The objectives of this study are to compare absolute values of acromial index (AI) and critical shoulder angle (CSA) obtained in both radiographs and magnetic resonance image (MRI) of the shoulder; and to compare the interobserver and intra-observer agreement for AI and CSA values measured in these image modalities. Methods Patients who had medical indication of investigating shoulders conditions through radiographs and MRI were included. Images were taken to two fellowship-trained shoulder surgeons, which conducted measurements of AI and CSA in radiographs and in MRI. Twelve weeks after the first evaluation, a second evaluation was conducted. Inter- and intra-observer reliability was presented as an Intraclass Correlation Coefficient (ICC) and agreement was classified according to Landis & Koch criteria. The differences between two measurements were evaluated using Bland-Altman plots. Results 134 shoulders in 124 subjects were included. Mean intra-observer ICC for CSA in X-rays and in MRI were 0.936 and 0.940, respectively; for AI, 0.908 and 0.022. Mean inter-observer ICC for CSA were 0.892 and 0.752 in X-rays and MRI respectively; for AI, ICC values were 0.849 and 0.685. All individual analysis reached statistical power (p< 0.001). Mean difference for AI values measured in X-rays and in MRI was 0.01 and 0.03 for observers 1 and 2, respectively. Mean difference for CSA values obtained in X-rays and MRI was 0.16 and 0.58 for observers 1 and 2, respectively. Conclusion Both MRI and X-rays provided high intra- and interobserver agreement for measurement of AI and CSA. Absolute values found for AI and CSA were highly correlated in both image modalities. These findings suggest that MRI is a suitable method to measure AI and CSA. Level of Evidence II, Diagnostic Study.

Resumo Objetivo Os objetivos deste estudo foram comparar os valores absolutos do índice acromial (IA) e do ângulo crítico do ombro (ACO) obtidos em radiografias e ressonâncias magnéticas (RM) do ombro e comparar a concordância interobservador e intraobservador dos valores de IA e ACO medidos nessas modalidades de imagem. Métodos Pacientes com indicação médica de investigação de doenças dos ombros por meio de radiografias e RM foram incluídos no estudo. As imagens foram levadas para dois cirurgiões de ombro treinados que realizaram medidas de IA e ACO em radiografias e RM. Doze semanas após a primeira avaliação, uma segunda avaliação foi realizada. A confiabilidade inter e intraobservador foi apresentada como coeficiente de correlação intraclasse (CCI) e a concordância foi classificada segundo os critérios de Landis e Koch. As diferenças entre duas medidas foram avaliadas por meio de gráficos de Bland-Altman. Resultados Cento e trinta e quatro ombros de 124 indivíduos foram incluídos no estudo. O CCI intraobservador médio para ACO em radiografias e RM foi 0,936 e 0,940, respectivamente; para IA, foi 0,908 e 0,022. O CCI interobservador médio para ACO foi 0,892 e 0,752 em radiografias e RM, respectivamente; para IA, os valores de CCI foram 0,849 e 0,685. Todas as análises individuais apresentaram poder estatístico (p < 0,001). A diferença média dos valores de IA em radiografias e RM foi 0,01 e 0,03 para os observadores 1 e 2, respectivamente. A diferença média dos valores de ACO em radiografias e RM foi 0,16 e 0,58 para os observadores 1 e 2, respectivamente. Conclusão Tanto a RM quanto as radiografias tiveram alta concordância intra e interobservador para medida de IA e ACO. Os valores absolutos de IA e ACO foram altamente correlacionados em ambas as modalidades de imagem. Esses achados sugerem que a RM é um método adequado para determinação de IA e ACO.

Acute Distal Biceps Tendon Injury: Diagnosis and Treatment / Lesões agudas do tendão distal do bíceps: Diagnóstico e tratamento

Abstract Acute distal biceps injuries clinically present with sudden pain and acute loss of flexion and supination strength. The main injury mechanism occurs during the eccentric load of the biceps. The hook test is the most significant examination test, presenting the highest sensibility and specificity for this lesion. Magnetic resonance imaging, the gold standard imaging test, can provide information regarding integrity and identify partial and/or complete tears. The surgical treatment uses an anterior or double approach and several reattachment techniques. Although there is no clinical evidence to recommend one fixation method over the other, biomechanical studies show that the cortical button resists better to failure. Although surgical treatment led to an 89% rate of return to work in 14 weeks, the recovery of high sports performance occurred in 1 year, with unsustainable outcomes.

Resumo As lesões agudas do tendão distal do bíceps se apresentam, clinicamente, com uma dor súbita associada a perda aguda de força de flexão e supinação. Seu principal mecanismo de lesão ocorre durante contração excêntrica do bíceps. O "Hook Test" é o principal teste semiológico, sendo o mais sensível e específico. A ressonância magnética, exame padrão ouro para o diagnóstico, pode fornecer informações sobre a integridade, identificando as lesões parciais e/ou completas. O tratamento cirúrgico pode ser realizado por duas vias principais: anterior e por dupla via porém as técnicas de reinserção tendínea são diversas não havendo evidência clínica que recomende um método de fixação em detrimento ao outro; embora o botão cortical apresente maior resistência a falha nos estudos biomecânicos. Com o tratamento cirúrgico o retorno as atividades laborais foi de 89% em 14 semanas (média) porém ao esporte de alto rendimento o prazo foi longo, média de 1 ano, e não duradouro.

Romantic relationship dissolutions are significantly associated with posttraumatic stress symptoms as compared to a DSM-5 Criterion A event: a case-case-control comparison.

Background: Non-marital romantic relationship dissolutions (RRDs) are common among emerging adult students (EAS) and may result in severe distress and suicidality. However, studies on RRDs in youth are limited to mental health sequelae of depression and prolonged grief. Little is known about the association between RRDs and posttraumatic stress symptoms (PTSS), and how this compares to posttraumatic stress symptoms following a traumatogenic event.Objective: We aimed to determine the association between RRDs and PTSS in an EAS sample; and how this compared to the association between posttraumatic stress symptoms and a Diagnostic and Statistical Manual 5th edition (DSM-5) traumatic event.Method: University students (N = 2,022; female = 71.1%; 18-25 years) completed a demographic and relationship questionnaire, the Life Events Checklist, the Adverse Childhood Experiences questionnaire, and the Posttraumatic Stress Checklist (PCL). We compared EAS with an RRD (n = 886) or a DSM-5 criterion A traumatic event (n = 592) against a control group (n = 544) exposed to a non-traumatic stressful life event. Utilising ANOVAs and Pearson's correlations we determined demographic and clinical variables associated with PTSS. ANCOVA and stepwise hierarchical regression analyses were used to determine between-group differences in PTSS.Results: Total trauma exposure and adverse childhood experiences, sex, monthly income, sexual orientation, and attachment style were significantly associated with PTSS. The RRD group had significantly higher PCL scores compared to the DSM and control groups. The mean PCL scores for both the RRD and DSM groups were above the cut-off score of 33, consistent with a probable posttraumatic stress disorder diagnosis. Significantly more RRD participants (72.9%) scored above the cut-off score of 33 than DSM-5 Trauma Group participants (55.4%).Conclusion: An RRD is a potentially traumatic event and is significantly associated with PTSS, similar to a posttraumatic stress disorder diagnosis.

Students may experience non-marital romantic relationship breakups as very painful, with various negative psychological, physical, and academic consequences. However, their painful experiences are often trivialised as something to 'just get over' and not acknowledged as potentially traumatic. Yet, using an attachment theory framework, breakups can be reconceptualised as subjectively traumatic.We explored the differences in posttraumatic stress symptoms of students who experienced a breakup, a traumatic event (as defined in psychiatry), and other non-traumatic life events. Students who experienced a breakup reported significantly highly posttraumatic stress symptoms.Acknowledging students' pain following a self-defined traumatic breakup can increase help-seeking behaviour and reduce the risk of intergenerational attachment trauma. Our findings warrant further research of breakups as potentially traumatogenic events.

Construcción y Validación de una Escala de Conductas de Separación de Pareja / Construction and Validation of a Scale of Couple Separation Behaviors

Resumen Las investigaciones en torno a una ruptura de pareja plantean medir las estrategias y conductas que las personas llevan a cabo para terminar sus relaciones románticas. Se propone entender la separación de pareja a partir del Modelo de Inversión de Rusbult (1979). Resulta relevante probar el modelo incluyendo elementos psicométricos que permitan comprender su validez al evaluar las conductas de separación. De esta forma el propósito de este estudio fue someter a prueba, un análisis exploratorio y confirmatorio de una escala que mida las conductas que las personas realizan para terminar su relación de pareja. Para ello se creó una escala de Conductas ante la separación de pareja a partir de un estudio exploratorio. La escala en su versión inicial contó con 50 reactivos en escala tipo Likert, aplicados en línea a 230 adultos de la Ciudad de México y Área Metropolitana. Al inicio del Análisis Factorial Exploratorio se obtuvo una escala final de 18 reactivos distribuidos en 4 factores (alejamiento, confrontación, depresión por separación e infidelidad) que explican el 68,47% de la varianza explicada con una confiabilidad de α = .871. Esta estructura fue corroborada por un Análisis Factorial Confirmatorio. Se encuentra una escala robusta y confiable, y se concluye que las conductas de separación evaluadas a partir del alejamiento con la expareja, que puede ser por medio de la comunicación o de ejercer conductas que transgreden como una infidelidad, afectan principalmente el estado emocional de las personas que lo viven.

Abstract Research on a couple's breakup aims to measure the strategies and behaviors that people carry out to end their romantic relationships. We propose to understand couple separation based on Rusbult's Reversal Model (1979). It is revealing to test the model including psychometric elements that allow us to understand its validity. Thus, the purpose of this study was to test an exploratory and confirmatory analysis of a scale that measures the behaviors that people perform to end their relationship. The initial version of the scale had 50 items on a Likert scale, applied online to 230 adults in Mexico City and Metropolitan Area. At the beginning of the exploratory factor analysis, a final scale of 18 items distributed in 4 factors (distancing, confrontation, depression due to separation and infidelity) was obtained, explaining 68.47% of the variance explained with a reliability of α = .871. This structure was corroborated by a Confirmatory Factor Analysis. A robust and reliable scale is found, and it is concluded that the separation behaviors evaluated from the distance with the ex-partner, which can be through communication or exercising behaviors that transgress such as infidelity, mainly affect the emotional state of the people who live it.

Ruptura prematura de membranas ovulares / Premature rupture of ovular membranes

La ruptura prematura de las membranas ovulares se define como la pérdida de la integridad del amnios y corion antes del inicio del trabajo de parto, afecta el 3 % de los embarazos, causa un tercio de los partos pretérminos, los cuales ocupan el 10,49 % de los nacimientos y es el origen de altos índices de morbimortalidad perinatal. En la actualidad, el manejo de esta patología se orienta principalmente en evitar los factores de riesgo, hacer un diagnóstico adecuado, determinar la edad gestacional en que ocurre, realizar el monitoreo exhaustivo del bienestar materno-fetal y en decidir el momento idóneo de finalización de la gestación para minimizar sus complicaciones. Debido a la compleja y lábil estructura histológica de las membranas ovulares, se ha dejado a un lado el tratamiento directo de la entidad el cual sería sellar o reparar el defecto en sí. En los últimos años, numerosos estudios y protocolos clínicos de prestigiosos centros asistenciales han servido como guía para el manejo de esta entidad, pero en muy pocos se observa una terapia destinada a la reparación de dichas membranas o en sellar tal defecto. Las evidencias científicas demuestran que la regeneración y reparación de las membranas es lenta y compleja y los tratamientos propuestos para reparar o sellar su defecto no han gozado de la aceptación científica para su aprobación, sin embargo, el uso del parche hemático transvaginal endocervical autólogo luce como una alternativa terapéutica prometedora(AU)

The premature rupture of the ovular membranes is defined as the loss of the integrity of the amnion and chorion before the on set of labor, affects 3% of pregnancies, causes athird of preterm births which occupy 10,49% of births and is the origin of high rates of perinatal morbidity and mortality. At present, the management of this pathology is mainly oriented towards avoiding risk factors, making an adequate diagnosis, determining the gestational age in which it occurs, carrying out exhaustive monitoring of maternal-fetal well-being and deciding the ideal moment to end the treatment. Pregnancy to minimizeits complications. Due to the complex and labile histological structure of the ovular membranes, the direct treatment of the entity has been set a side, which would be to seal or repairthe defect it self. In recent years, numerous studies and clinicalprotocols from prestigious health care centers have served as aguide for the management of this entity, but very few have observed a therapy aimed at repairing said membranes or sealing such a defect. Scientific evidence shows that the regeneration and repair of the membranes is slow and complex and the treatment sproposed to repair or seal their defect have not enjoyed scientific acceptance for their approval, how ever, the use of the autologous endocervical transvaginal blood patch looks like a promising therapeutic alternative(AU)

Spontaneous hemoperitoneum during pregnancy: three case reports and literature review.

OBJECTIVES: This case report presented cases with spontaneous hemoperitoneum during pregnancy. CASE REPORT: Case 1 presented with acute abdominal pain with signs of shock. Cases 2 and 3 both presented with stable vital signs and the sudden decline of fetal heart rate. Cesarean section was performed at 27, 36+4, and 34 gestational weeks, respectively. Bleeding sites were founded on the surface of the uterus or the parametrium. The perinatal outcome was stillbirth, live birth, and neonatal severe asphyxia. CONCLUSION: Careful physical examination, strict monitoring of vital signs, and timely surgical intervention are critical for improving the prognosis.

OBJETIVO: Este caso clínico presentó casos con hemoperitoneo espontáneo durante el embarazo. REPORTE DEL CASO: El caso 1 presentó dolor abdominal agudo con signos de shock, los casos 2 y 3 se presentaron ambos con signos vitales estables y la disminución repentina de la frecuencia cardíaca fetal. La cesárea se realizó a las 27, 36 + 4 y 34 semanas de gestación, respectivamente. Los sitios de sangrado se encontraron en la superficie del útero o el parametrio. CONCLUSIÓN: Un control estricto de los signos vitales y una intervención quirúrgica oportuna son fundamentales para mejorar el pronóstico.

Ruptura esplénica después de terapia anticoagulante en un paciente con antecedente de COVID-19: reporte de caso.

We present the case of a 75-year-old man with a history of COVID-19 and splenic infarct treated with enoxaparin, who presented with intense abdominal pain and tomographic findings of free peri-splenic fluid and a hyperdense image in the spleen. An emergency laparotomy was performed, with findings of a splenic rupture at the vascular hilum. Spontaneous splenic rupture is a rare and fatal entity that should be suspected in a patient with history of COVID-19 who presents with acute abdominal pain after the administration of heparin.

Presentamos el caso de un varón de 75 años con antecedente de COVID-19 e infarto esplénico tratado con enoxaparina, quien inició con dolor abdominal intenso y hallazgos tomográficos de líquido libre periesplénico, así como una imagen hiperdensa en el bazo. Fue sometido a laparotomía de urgencia, encontrando una ruptura esplénica a nivel del hilio vascular. La ruptura esplénica espontánea es una condición rara y potencialmente fatal, por lo que se deberá tener un alto índice de sospecha ante un paciente con antecedente de COVID-19 que inicie con dolor abdominal agudo posterior a la administración de heparina.

Comparison of strip meniscometry and Schirmer tear test results and tear film breakup time between healthy dogs and dogs with dry eye disease / Comparação entre o teste de meniscometria em tira, o teste lacrimal de Schirmer e o tempo de ruptura do filme lacrimal em cães normais e com olho seco

ABSTRACT Purpose: To compare strip meniscometry and Schirmer tear test 1 results and tear film breakup time between dogs with normal eyes and dogs diagnosed with keratoconjunctivitis sicca. Methods: One-hundred fifty-six eyes of 78 dogs, 88 normal eyes, and 68 eyes diagnosed with keratoconjunctivitis sicca were included in the study. The tests were performed in the following sequence: Schirmer tear test 1 was used to allocate the dogs to the normal or keratoconjunctivitis sicca group, followed by the strip meniscometry test and tear film breakup time measurement. Results: The results (mean ± standard deviation) of the tests in the normal group were as follows: Schirmer tear test 1, 22.75 ± 3.88 mm/min; strip meniscometry test, 10.01 ± 2.35 mm/5 sec; and tear film breakup time, 25.82 ± 5.47 sec. In the keratoconjunctivitis sicca group, the results were as follows: Schirmer tear test 1, 6.10 ± 4.44 mm/min; strip meniscometry test, 3.03 ± 2.62 mm/5 sec; and tear film breakup time, 10.78 ± 4.23 sec. The Spearman correlation coefficient in the keratoconjunctivitis sicca group was very high, with a significant difference between the strip meniscometry test and Schirmer tear test 1 (r=0.848, p<0.001), and moderate and significant between the strip meniscometry test and tear film breakup time (r=0.773, p<0.001). The cutoff for the strip meniscometry test for keratoconjunctivitis sicca was 7.0 mm/5 sec. Keratoconjunctivitis sicca was suspected when the values were <10 mm/5 sec. Conclusions: This study provided strip meniscometry test values from dogs with normal eyes and eyes with keratoconjunctivitis sicca, with high sensitivity and specificity compared with those of the Schirmer tear test 1. In the future, the strip meniscometry test may be another important quantitative test and could complement the gold standard Schirmer tear test for the diagnosis of keratoconjunctivitis sicca in dogs, an excellent animal model for the study of the disease.

RESUMO Objetivo: Comparar o teste de meniscometria em tira com o teste lacrimal de Schirmer 1 e o tempo de ruptura do filme lacrimal, em cães com olhos normais e cães com diagnóstico de ceratoconjuntivite seca. Métodos: Cento e cinquenta e seis olhos de 78 cães, 88 olhos normais e 68 olhos com diagnóstico de ceratoconjuntivite seca. Os testes foram realizados na seguinte sequência: o teste lacrimal de Schirmer 1 foi utilizado para alocar os cães no grupo normal ou no grupo ceratoconjuntivite seca, seguido pelo teste de meniscometria em tira e tempo de ruptura do filme lacrimal. Resultados: As médias e desvios-padrão para os olhos normais foram: teste lacrimal de Schirmer 1 = 22,75 ± 3,88 mm / min; teste de meniscometria em tira = 10,01 ± 2,35 mm / 5 seg; tempo de ruptura do filme lacrimal = 25,82 ± 5,47 seg; e para os olhos do grupo ceratoconjuntivite seca foram: teste lacrimal de Schirmer 1 = 6,10 ± 4,44 mm / min; teste de meniscometria em tira = 3,03 ± 2,62 mm / 5 seg; tempo de ruptura do filme lacrimal = 10,78 ± 4,23 seg. O teste de correlação de Spearman no grupo ceratoconjuntivite seca foi muito alto, com diferença significativa entre teste de meniscometria em tira e teste lacrimal de Schirmer 1 (r=0,848, p<0,001), moderada e significativa entre teste de meniscometria em tira e tempo de ruptura do filme lacrimal (r=0,773, p<0,001). O cut-off para teste de meniscometria em tira para ceratoconjuntivite seca foi identificado em 7,0 mm / 5 seg, valores abaixo de 10 mm / 5 seg podem ser considerados suspeitos para KCS. Conclusões: Este estudo forneceu valores de teste de meniscometria em tira em olhos normais e com ceratoconjuntivite seca em cães, revelando alta sensibilidade e especificidade em comparação com o teste lacrimal de Schirmer 1. No futuro, o teste de meniscometria em tira pode ser outro teste quantitativo importante e pode complementar o teste lacrimal de Schirmer padrão ouro para o diagnóstico de ceratoconjuntivite seca em cães, um excelente modelo animal para o estudo de ceratoconjuntivite seca.

Observing and interpreting clinical process: Methods and findings from 'Layered analysis' of parent-infant psychotherapy.

This paper describes a method for investigating clinical process, Layered Analysis, which combines therapist countertransference reports and multi-faceted microanalytic research approaches. Findings from the application of Layered Analysis to video-recorded micro-events of rupture and repair in four psychoanalytic parent-infant psychotherapy sessions are presented. Layered analysis showed that countertransference and observation are complementary perspectives, which enable concomitant study of interactive events, conscious internal experiences, as well as nonconscious and unconscious elements of therapeutic interaction. Interactional rupture and repair were found to constitute co-constructed micro-events that occurred fleetingly and often implicitly, and differed in the structure, coherence and flow of interactions and in the relationship between verbal and nonverbal communication. Furthermore, interactional ruptures were found to sometimes 'get into' the therapist and transiently disrupt their self-organization, such that the therapist became a locus of disruption for the patient(s), actively contributing to the rupture, which thus became embedded in the therapeutic system. Interactive repair was found to be most often initiated by the therapist and to be underpinned by the therapist re-establishing self-regulation, through metabolizing embodied and verbal aspects of the rupture. Studying such processes can enhance our understanding of clinical process, inform therapist training and clinical supervision, and contribute to clinical outcomes.

Este ensayo describe un método para investigar un proceso clínico, Análisis en Capas, el cual combina los reportes de contratransferencia del terapeuta y los acercamientos investigativos micro analíticos multifacéticos. Se presentan los resultados de aplicar Análisis en Capas a micro eventos, grabados en video, de ruptura y reparación en cuatro sesiones de sicoterapia sicoanalítica de progenitor e infante. Los Análisis en capas mostraron que la contratransferencia y la observación son perspectivas complementarias que, en combinación, permiten el estudio concomitante de eventos interactivos, experiencias internas conscientes, así como elementos no conscientes de la interacción terapéutica. Adicionalmente, los resultados mostraron que la ruptura y la reparación constituyen micro eventos co-construidos que ocurren muy fugazmente y a menudo implícitamente, y que difieren en la estructura, coherencia, flujo de interacciones y en la relación entre la comunicación verbal y no verbal. Es más, rupturas interaccionales pueden 'meterse en' el terapeuta y transitoriamente interrumpir su autoorganización, de manera que el terapeuta se convierte en un punto de interrupción para el paciente y la ruptura pasa a ser parte del sistema terapéutico. La reparación interactiva está sostenida por, y depende de, la metabolización del terapeuta de los aspectos incorporados y verbales de la ruptura. Estudiar tales procesos puede mejorar nuestra comprensión del proceso clínico y ser usado en entrenamiento y supervisión de terapeutas.

Cet article décrit une méthode d'investigation du processus clinique d'Analyse Multidimensionnelle en Couches, qui combine des rapports de contre-transfert du thérapeute et des approches de recherche micro-analytique à facettes multiples. Les résultats de l'application de l'analyse multidimensionnelle en couches à des micro-événements enregistrés à la vidéo de rupture et de réparation dans quatre séances de psychothérapie psychanalytiques parent bébé sont présentés. L'analyse multidimensionnelle en couches a montré que le contre-transfert et l'observation sont des perspectives complémentaires qui, combinés l'un avec l'autre, permettent une étude concomitante d'événements interactifs, d'expériences internes conscientes et d'éléments non-conscients de l'interaction thérapeutique. De plus, les résultats ont montré que la rupture et la réparation constituent des micro-événements co-construits, qui se passent très fugacement et souvent implicitement et diffèrent en structure, cohérence et flux des interactions et dans la relation entre la communication verbale et non verbale. Enfin les ruptures interactionnelles peuvent 'entrer' dans le thérapeute et perturber de façon transitoire leur auto-organisation, de telle manière que le thérapeute devient le locus de la perturbation pour le/la/les patient(e/s) et la rupture s'encastre dans le système thérapeutique. La réparation interactive est étayée par, et elle en dépend également, la métabolisation d'aspects verbaux et incarnés de la rupture du thérapeute. L'étude de tels processus peut améliorer notre compréhension du processus clinique et être utilisée dans la formation et la supervision des thérapeutes.

Un caso de neumonía organizada tras la ruptura intracapsular de implantes mamarios de silicona / A case of organized pneumonia after intracapsular rupture of silicone breast implants

La neumonía organizada es una entidad poco frecuente, caracterizada por la formación de conglomerados fibroblásticos intraalveolares conocidos como cuerpos de Masson, que puede ser criptogénica o secundaria a una respuesta inmunitaria a diversos estímulos, tales como enfermedades hematológicas, autoinmunitarias, exposición a sustancias químicas, fármacos, tóxicos, etc. Detectada y tratada de forma precoz, suele tener una buena respuesta a la corticoterapia, aunque si se diagnostica de forma tardía, la afectación pulmonar puede ser extensa, y, además, si el estímulo antigénico persiste, la respuesta al tratamiento será incompleta. Presentamos el caso clínico de una paciente de 65 años de edad quien hace 18 meses aproximadamente presentó la rotura intracapsular de sus implantes mamarios, 27 años después de su colocación. Con el mismo tiempo de evolución ha desarrollado progresivamente disnea, tos seca y dolor inframamario, habiendo llegado al diagnóstico de neumonía organizada bilateral difusa, asociada a dicha rotura de implantes.

Organizing pneumonia is a rare entity, characterized by the formation of intraalveolar fibroblastic conglomerates known as Masson bodies, which may be cryptogenic or secondary to an immune response to various stimuli, such as hematological, autoimmune diseases, exposure to chemical substances, drugs, toxics, etc. If it is detected and treated early, it usually has a good response to corticosteroid therapy, although if it is diagnosed late, the lung involvement can be extensive, and furthermore, if the antigenic stimulus persists, the response to treatment will be incomplete. We present the clinical case of a 65-year-old patient who had intracapsular rupture of her breast implants approximately 18 months ago, 27 years after their placement. With the same evolution time, she progressively developed dyspnea, dry cough and under mammary pain, having reached the diagnosis of diffuse bilateral organizing pneumonia, associated with implant rupture.
