ABSTRACT

Las habilidades psicomotrices son un pilar fundamental del aprendizaje en odontología y clásicamente han sido trabajadas a través de la simulación o atención de pacientes. Durante el confinamiento debido a COVID-19, los estudiantes no tuvieron factibilidad de realizar procedimientos preclínicos. Debido a esto, se implementaron sesiones de entrenamiento de habilidades psicomotrices, en formato online, que permitieran preparar a los estudiantes durante el confinamiento para el retor no a la clínica. Se implementaron sesiones de entrenamiento psicomotriz a través de la utilización de materiales de artes plástica s e instrumental odontológico en formato online y guiados por una Terapeuta ocupacional. Para su medición, se realizó un estudio de casos y controles, donde los grupos se seleccionaron por conveniencia entre estudiantes que participaron de las sesiones y aquellos que tuvieron la formación virtual tradicional. La experiencia se evaluó a través cuestionario de autopercepción contestado por los estudiantes con respuestas en una escala de Likert y se comparó a través de pruebas estadísticas no paramétricas. Se recolectó una muestra total de 27 estudiantes, con una edad promedio de 23,7 años. Al comparar las respuestas de ambos grupos, los estudiantes del grupo casos percibieron significativamente una mejor sujeción de objetos pequeños utilizando pinzas, manipulación de instrumentales manuales y rotatorios de manera más precisa y mejor coordinación entre ambas manos durante un procedimiento simple en boca en comparación al grupo que no participó de las mismas. El entrenamiento de habilidades psicomotrices realizadas durante el periodo de confinamiento mostró resultados positivos en la percepción de las habilidades psicomotrices de los estudiantes, siendo una estrategia de bajo costo para ser implementada durante la formación de destrezas de los estudiantes de odontología en diferentes contextos. Sin embargo, para una mejor implementación debe estar en conjunto a estrategias de simulación para ser totalmente efectiva.


Psychomotor skills are a fundamental pillar of learning in dentistry and traditionally have been worked on through simulation or patient care. During the confinement due to COVID-19, students were not able to perform preclinical procedures. Due this, psychomotor skills training sessions were implemented, in online format to prepare students during confinement for the return to the patient care. Psychomotor training sessions were implemented using plastic arts materials and dental instruments in online format and guided by an occupational therapist. For its measurement, a case-control study was carried out, where the groups were selected by convenience between students who participated in the sessions and those who had traditional virtual training. The experience was evaluated through a self- perception questionnaire answered by the students with answers on a Likert scale and compared through non- parametric statistical tests. A total sample of 27 students was collected, with an average age of 23.7 years. When comparing the responses between groups, the students in the case group perceived significantly better grasping of small objects using forceps, more precise manipulation of hand and rotary instruments and better coordination between both hands during a simple mouth procedure compared to the group that did not participate in the same. The psychomotor skills training performed during the confinement period showed positive results in the perception of psychomotor skills of the students, being a low-cost strategy to be implemented during the skills training of dental students in different contexts. However, for a better implementation it should be in conjunction with simulation strategies to be fully effective.

ABSTRACT

Introduction: Periprosthetic infection (PPI) is one of the most devastating complications of total knee arthroplasty (TKA). The incidence described in the literature is 2.4% and the most frequently isolated bacteria are Staphylococcus Aureus and Staphylococcus Coagulase-Negative (Gram positive). Polymicrobial infections represent between 10 to 37% and negative cultures between 7 to 15%. Methodology: Descriptive and retrospective study that consisted of reviewing the TKA database of the Regional Hospital of Talca during the 2018-2020 period, where knee PPIs were identified according to the diagnostic criteria validated in 2018. The cultures of patients diagnosed with PPI were reviewed, analyzing the antibiogram and resistance profile. Results: During 2018-2020, 459 TKAs were performed in our center, diagnosing 30 PPIs of the knee. 47% of PPIs were acute and 53% chronic. The results of the cultures were negative in 26.6%, 23.3% Methicillin Sensitive Staphylococcus Aureus; 13.3% Methicillin Resistant Staphylococcus Epidermidis and 13.3% of the cultures were polymicrobial. Discussion: Highlights the high resistance to methicillin, especially of Staphylococcus Epidermidis. This opportunistic pathogen has the ability to form a biofilm and, thanks to its genomic flexibility, rapidly acquires resistance to antibiotics. Polymicrobial infections have a synergistic effect that favors the persistence of the infection, which is why they will require a greater number of surgeries and prolonged antibiotic therapy. Pruebas especiales como la sonicación podrían aumentar las posibilidad de identificar al microorganismo. Conclusion: In these three years of follow-up, the PPI rate has been higher than reported annually in the literature. Gram-positive microorganisms continue to predominate, but with an increase in the rate of resistant to methicillin. Also, highlight the number of negative cultures. There would be a possible benefit theoretical in optimizing antibiotic prophylaxis in view of the large percentage of methicillin resistance and in seeking new ways to reduce negative cultures.

ABSTRACT

Tibial pilon fractures are a complex injury to treat due to the great involvement of soft and bone tissues. The classic surgical treatment is based on open reduction with internal fixation (ORIF), adding morbidity to the soft tissues, increasing the risk of complications. This has motivated the development of minimally invasive and/or percutaneous techniques to reduce complications, and with the advent of arthroscopy, achieve anatomical reductions. METHODS: A retrospective observational study of twelve patients with tibial pilon fractures who were treated in our center with minimally invasive and/ or percutaneous osteosynthesis with arthroscopic support was carried out between January 2019 and June 2021. Fractures were characterized using the AO/OTA classification for tibial pilon. Age, sex, fracture mechanism, exposure and initial management in the emergency department (cast immobilization or external fixation), definitive treatment, complications and clinical and functional evaluation twelve months after definitive osteosynthesis. For this last point, plantar flexion, dorsiflexion and the AOFAS and FAOS Score were measured. RESULTS: The operated patients were 12, 8 were men (67%) and 4 were women (33%). The average age was 49 (17-68) years. The definitive treatment was carried out after an average of 8 days (5-12 days). Surgical treatment schemes were as follows: percutaneous osteosynthesis with medial anatomical plate and arthroscopic support (OPAA), minimally invasive osteosynthesis with cannulated screws and arthroscopic support (OMIAA) and osteosynthesis with external circular guide and arthroscopic support (OTCAA). In the AOFAS Score, three patients had excellent results (≥ 90 points), 6 patients had good results (≥ 80 points) and 3 patients had acceptable results (≥ 70 points). In the FAOS Score, eight patients had over 80% (good results) and 4 patients had over 60% (accep - table results). DISCUSSION: Historically, tibial pilon fractures have been considered non-reconstructable and with poor long-term results. Initially this paradigm changed with the principles of Rüedi for the reconstruction of the tibial pilon and improve the results. ORIF has been widely used until today, it allows achieving an anatomical joint reduction, it allows to give stability and length to the fibula, graft contribution and sta - bilization with the medial plate. Today this concept is changing again, since the emphasis is on the care of the soft tissues to allow a better recovery of the patient and reduce the complications of the classic approach, it is in this context that the appearance of minimally invasive and/or percutaneous techniques with arthroscopic assistance has allowed us to have excellent functional and clinical results with less da - mage to the soft tissues. CONCLUSION: The proper management and care of the soft tissues in a high-energy fracture of the tibial pilon is essential to obtain favorable clinical results and thus achieve restoration of ankle function. Percutaneous and minimally invasive management has optimized management of the tibial pilon, redu - cing the rates of complications, amputation, and pri - mary arthrodesis.

ABSTRACT

Total hip arthroplasty (THA) is a safe and effective procedure in patients with end-stage ostheoarthritis. In the last years the indication for THA is increasingly in younger patients, associated with rising of life expectancy, this imply an increase in revision surgeries for various causes such as: aseptic loosening, fractures and infections. In this context and in view of the need to replace the femoral component, alternatives to the classic extended trochanteric osteotomy (ETO) arise, such as the anterior cortical window (ACW), which allows the rate of complications to be reduced with excellent results. We present the case of a 51-year-old patient who sustained one episode of dislocation, who required revision surgery due to aseptic loosenig, where the ACW was used for the extraction of the stem. In addition, a review of the literature was made to show advantages and complications regarding ETO.

ABSTRACT

Total hip arthroplasty is a successful procedure with high rates of functional satisfaction and pain relief. A large number of patients with bilateral hip pathology will require both hip joint replacement, from there born the inquietude to knowing benefits and disadvantage of bilateral simultaneous hip arthroplasty. We present a female patient case who developed bilateral hip osteoarthritis secondary to development dysplasia of the hip which was surgically managed with bilateral arthroplasty at one time. We show a follow-up report of the case and a review of the literature to know the main advantages of this new current of hip arthroplasty in patients with bilateral hip pathology

ABSTRACT

El angioedema hereditario (AEH) es una enfermedad genética rara, con una prevalencia aproximada entre 1 por cada 50.000 habitantes, caracterizada por episodios de edemas a nivel subcutáneo y de mucosas (abdominal, genitourinario, respiratoria), siendo potencialmente mortal cuando hay afectación de la laringe. En Perú se estiman 600 pacientes con AEH. El AEH se puede clasificar del siguiente modo: con deficiencia del inhibidor de C1 (tipos I y II), y sin deficiencia del inhibidor de C1 (denominado anteriormente tipo III). El diagnóstico de laboratorio incluye prueba de complemento C4, prueba cuantitativa y cualitativa para inhibidor de C1 esterasa, y estudios genéticos.


Hereditary angioedema (HAE) is a genetic rare disease with a prevalence of approximately 1 per 50,000 inhabitants, characterized by episodes of edema at the subcutaneous level and mucous membranes (abdominal, genitourinary, respiratory), being potentially fatal when there is involvement of the larynx. In Peru, there are an estimated 600 patients with HAE. HAE can be classified as follows: with C1 inhibitor deficiency (types I and II), and without C1 inhibitor deficiency (previously called type III). Laboratory diagnosis includes C4 complement test, quantitative and qualitative tests for C1 inhibitor esterase, and genetic studies. In this first part of the Clinical Practice Guide, we present the recommendations for the diagnostic approach of HAE.

ABSTRACT

ABSTRACT: A variety of periodontal plastic surgery techniques have been proposed to correct aesthetic and functional problems of periodontal tissues. The most common procedure uses the connective tissue graft from the palate. However, patient discomfort and the limited quantity of palatal tissue results in many cases where the surgeon uses connective tissue substitutes. In this case report, we describe the use of a human dermal matrix for gingival volume augmentation in the lower incisors with a novel modified VISTA technique stabilizing the flap with sutures and cyanoacrylates, avoiding comorbidity of a second surgical site. The follow up at 6 months showed an increase in gingival thickness and a reduction in recessions length.

ABSTRACT

ResumenEl artículo aborda las dificultades en el diagnóstico psiquiátrico por las características propias de estos trastornos que, junto con la definición de lo patológico desde la prescripción de lo moralmente aceptado y los conflictos de interés entre la psiquiatría y las compañías farmacéuticas, han llevado a cuestionar las categorías diagnósticas en este campo del saber. Se argumenta la necesidad de contar con categorías, aunque imperfectas, para el abordaje clínico inicial, para el disfrute de los derechos laborales y en atención médica, para la investigación en este campo y para la definición y asignación de recursos en políticas públicas basadas en evidencia. Se explica cómo el personal de salud debe evaluar la percepción subjetiva del padeciente acerca de su sintomatología, malestar y disfunción, aunado a una cuidadosa observación del comportamiento no verbal y paraverbal, para proponer un diagnóstico sindrómico presuntivo y el abordaje inicial. Los criterios diagnósticos del DSM o la CIE no se deben aplicar como un "checklist" que resulta en un diagnóstico final incuestionable.Por último, se hace un llamado a desestigmatizar las categorías psiquiátricas. Se ha demostrado que el temor a la estigmatización resultante del etiquetado en psiquiatría, contribuye a que las personas no busquen ayuda profesional para trastornos en los que el tratamiento psicoterapéutico y farmacológico mejoran el malestar, calidad de vida y funcionalidad.


AbstractThis article addresses the difficulties in psychiatric diagnoses together with the practical need for these labels. The characteristics of these disorders, the definition of what is considered pathological by morally prescribed standards and the conflicts of interest between psychiatry and pharmaceutical companies, have led to question the diagnostic categories in this field of knowledge. We argue that diagnostic categories are necessary, for the initial clinical approach; for access to medical care, disability and other legal rights; for research in this field; and for the definition and allocation of resources in evidence-based public policies. We discuss how clinical practitioners should assess the subjective perception of the sufferer of their symptoms, discomfort and dysfunction, together with a careful observation of non-verbal and para-verbal behavior, to propose a presumptive syndromic diagnosis and the initial approach. The diagnostic criteria of the DSM or ICD should not be applied as a "checklist" resulting in an unquestionable final diagnosis. Finally, we make a call to de-stigmatize the psychiatric categories. Fear of stigmatization resulting from psychiatric labels has been shown to contribute to sufferers not seeking professional help, for disorders in which psychotherapeutic and pharmacological treatment, improves symptomatology, quality of life and functionality.

ABSTRACT

Justificación y objetivos: la heterogeneidad clínica del trastorno afectivo bipolar tipo I constituye uno de los principales desafíos en el diagnóstico de dicha enfermedad. Se necesitan múltiples fuentes de información que permitan definir el perfil clínico, demográfico y comorbilidad con otras enfermedades psiquiátricas. El estudio tiene como objetivo analizar las características clínicas, sociodemográficas y curso del trastorno, en familias costarricenses con uno o más miembros afectados. Métodos: se estudió a 167 pacientes con trastorno afectivo bipolar tipo I, los cuales provenían de diferentes familias de Costa Rica. El diagnóstico clínico se llevó a cabo mediante el proceso de mejor estimado diagnóstico y caracterización clínica dimensional a través de la vida. El análisis estadístico incluyó regresión logística, así como curvas de sobrevivencia de Kaplan-Meier. Resultados: 93 sujetos (55,7%) fueron mujeres. La edad promedio al momento de la entrevista fue de 43,25 (DE=13,90). De los probandos con edad de inicio de enfermedad posterior a 20 años, 24 (14,0%) familiares de primer grado tenían trastorno bipolar tipo I (x²=3,56, p=0,05); OR=1,7; 95% CI=1,2-2,7. La edad promedio de inicio para el trastorno por uso de sustancias en varones, fue 17 años (DE=0,4), versus 23 años (DE=3,2) para mujeres (x²=3.90, p=0.04). Varones con trastorno bipolar tipo y uso comórbido de sustancias presentaron menor edad de inicio de cualquier síntoma psiquiátrico, que aquellos sin TUS (x²=8,99, p=0,003). Conclusiones: el trastorno por uso de sustancias seguido por los trastornos de ansiedad, constituyen las condiciones comórbidas más frecuentes en el trastorno afectivo bipolar tipo I. La edad de inicio más temprana de trastorno afectivo bipolar tipo I en probandos, se asocia con mayor número de afectados por dicho trastorno en familiares de primer grado.


Explanation and objectives: Clinical heterogeneity is one of the main challenges to diagnose bipolar disorder type I. Multiple sources of information are required to define comorbidity with other psychiatric disorders, as well as the clinical and demographic characteristics of this mental disorder. The objective of this study is to analyze the socio-demographic, clinical and course characteristics of bipolar disorder type I in Costa Rican families with more than one member affected. Methods: A sample of 167 individuals with bipolar disorder type I from different families in Costa Rica was studied. The clinical diagnosis was carried out through a best estimate diagnostic procedure and a characterization of lifetime clinical dimensions. Logistic regression and Kaplan-Meier survival analyses were used for the statistical analysis. Results: Ninety-three subjects (55.7%) were females and the mean age at the time of the interview was 43.25 (SD=13.90). In the case of probands with age of onset for bipolar disorder type I after age 20 years, 24 (14.0%) first-degree relatives had been diagnosed with bipolar disorder type I (x2=3.56, p=0.05); OR=1.7; 95% CI=1.2-2.7. The median for age of onset of substance use disorder in males was 17 (SE=0.4) compared to 23 (SE=3.2) in females (x2=3.90, p=0.04). Bipolar disorder type I males with comorbid substance use disorder reported earlier age of onset of any psychiatric symptom than those without substance use disorder (x2=8.99, p=0.003). Conclusions: Substance use disorder, followed by anxiety disorders are the most prevalent comorbid conditions in bipolar disorder type I. Early onset of bipolar disorder type I in probands was associated with higher number of relatives suffering from bipolar disorder type I.

ABSTRACT

Antecedentes: la salud es un proceso social que tiene como fin el bienestar físico y mental del individuo a través de todas las etapas de su vida. A pesar de numerosos esfuerzos, en Costa Rica, el abordaje en salud mental se ha basado principalmente en la atención de la enfermedad y muy poco en la prevención. Se resumen las conclusiones sobre el Foro de Salud Mental. Métodos: foro de discusión sobre salud mental con la participación de prestadores de servicios, investigadores, los que definen las políticas a nivel gubernamental y los usuarios. Resultados: participación de 148 representantes de distintas instituciones y organizaciones. Se resalta la ausencia de indicadores salutogénicos y escasa medición del impacto en las acciones de prevención y promoción. Existe inconformidad con la calidad y acceso a la atención. Se documenta un único programa de rehabilitación psicosocial con pocos recursos intermedios. Discusión: el proceso de consulta y discusión incluye a usuarios quienes, con los otros autores, identifican necesidades y proponen posibles soluciones en salud mental. Dificultad para la implementación de un plan de acción concreto constituye la principal limitante en promoción, atención y rehabilitación...

ABSTRACT

Tener un instrumento de valoración nutricional al ingreso del paciente al hospital, no ayuda a tomar medidas desde ese punto de vista desde inicio del ingreso, lo que permite un mayor éxito de los tratamientos. En la literatura se reporta que un 30-50 por ciento los pacientes a su ingreso a un centro hospitalario tiene algún grado de desnutrición. Nuestra estadística que practicándose una valoración global subjetiva por personal entrenado, se puede detectar hasta un 62 por ciento de pacientes, con problema nutricional en nuestro hospital, los cuales se beneficiarían de una atención nutricional primaria

ABSTRACT

El empleo de sondas de doble luz tiene indicaciones precisas en cirugía pulmonar, ortopédica, cardiovascular, oncológica, de tubo digestivo a nivel torácico y en las unidades de cuidados intensivos respiratorios. En la cirugía de tórax, la intubación selectiva proporcional el aislamiento pulmonar evitando la contaminación el pulmón sano con secreciones y/o sangrado proveniente del pulmón enfermo. En las fístulas broncopleurocutáneas, la fuga aérea del volumen corriente se evita con la utilización de estas sondas. Las sondas de doble luz presentan una evolución en sus características físicas desde su aparición hasta la actualidad, la sonda tipo Carlens con espolón carinal tiene la posibilidad de lesionar el árbol traqueobronquial y por contar con una luz interna en forma oval, aumenta la resistencia en la vía aérea, dificultando la ventilación y la aspiración de secreciones; la de tipo Robertshaw, por su material de fabricación y diseño minimiza el trauma de la vía aérea, facilita la técnica de intubación, disminuye la resistencia para la ventilación y proporciona un margen de seguridad adecuado para la intubación bronquial selectiva, dependiendo todo ésto de la marca de fabricación. Por tanto, es imprescindible conocer las características físicas de las sondas, seleccionar el tamaño adecuado para cada paciente, dar la profundidad requerida, obtener el mayor margen de seguridad, aplicar las diferentes técnicas de intubación selectiva y adecuar la presión en el inflado de los globos para minimizar el daño al árbol traqueobronquial y así obtener el mayor beneficio de la utilización de estas sondas
