ABSTRACT

Objetivo: Estudiar el efecto del manejo multidisciplinario (MMD) de úlcera de PD (UPD) en un Hospital de Chile durante el período 2017-2020. Materiales y Métodos: Estudio comparativo, observacional y retrospectivo, se analizó una base de datos disociada compuesta por 111 pacientes atendidos en el periodo 2017-2020 y se comparó con los datos de 121 pacientes con UPD atendidos en el mismo Hospital sin MMD en periodo 1998-2005. Para los estudios analíticos se usó prueba de Chi cuadrado, prueba exacta de Fisher, U de Mann Whitney y Kruskal Wallis. Resultados: La tasa de reamputaciones mayores con MMD fue de un 2,7%, el 91,2% de los pacientes atendidos con MMD lograron mejorar la condición clínica de la herida, sin embargo, en pandemia por SARCOV-2 la mejoría se redujo a un 78,2%. La tasa de cicatrización completa de la herida con MMD fue de 77,8% v/s 31,4% sin MMD (p < 0,0001) y la tasa de reamputación general sin MMD fue de 47,1% v/s 12,6% con MMD (< 0,0001). La recidiva fue de un 11,7% con MMD v/s 100% a los cuatro años sin MMD (p < 0,0001). Discusión y Conclusión: Observamos que el MMD de la UPD logra mejores tasas de efectividad de la intervención que pacientes sin MMD, mostrándose mejores tasas de cicatrización de la herida, tasa de reamputación mayor, y tasa de recidiva. Por lo tanto, un MMD podría contribuir, significativamente, al rescate de la extremidad afectada.


Objective: To assess the effect of a multidisciplinary approach on patients with diabetic foot ulcer (DFU) in a Hospital in Chile from 2017 to 2020. Material and Method: The study is observational, comparative, and retrospective. The data from 111 patients were analyzed anonymously during 2017-2020. It was compared with old data from a group of121 patients treated in the same hospital but without a multidisciplinary approach. To gather the data the Chi-square test, Fisher's exact test, the U of Mann Whitney, and the Kruskal Wallis were used. Results: It was found that the rate of major re-amputations in patients undergoing treatment with a multidisciplinary approach was 2.7%. Furthermore, 91.2% of patients treated with a multidisciplinary approach improved the clinical condition of the wound. However, During the SARCOV-2 pandemic, the improvement rate was reduced to 78.2%. The complete wound healing rate was 77.8% in patients treated with a multidisciplinary approach versus 31.4% without a multidisciplinary approach (p < 0.0001). The overall re-amputation rate on patients without a multidisciplinary approach was 47.1% versus 12.6% on patients with a multidisciplinary approach (< 0.0001). The recurrence rate was 11.7% in patients with a multidisciplinary approach versus 100% in patients without a multidisciplinary approach (p < 0.0001). Conclusion: We observed finally, we observed that a multidisciplinary approach helped the DFU patients to achieve better intervention effectiveness rates, showing better rates of wound healing, higher re-amputation rate, and recurrence rate. Therefore, a multidisciplinary approach could contribute significantly to the improvement of the affected limb.

ABSTRACT

Osteoarthrosis of the knee is one of the most important causes of disability around the world, being total knee arthroplasty (TKA) a cost-effective surgical procedure for treating its severe stage when all knee compartments are compromised. Despite the good functional results and good survival of the implants and of the patients, still, 15 to 20% of the patients are dissatisfied after surgery. One of the causes of dissatisfaction is persistent pain located in the anterior part of the knee, which leads to controversy over whether to perform the patellar replacement. Advantages and complications are described in both scenarios, and neither is superior to the other in pain and implant survival. In the case of TKA without patellar replacement, the position of the femoral component plays a crucial role in achieving normal patellar tracking. The current challenge is to determine those clinical and radiological variables that allow us to predict the absence of long-term anterior pain in patients who require TKA and who do not undergo patellar replacement.

ABSTRACT

RESUMEN El fibroadenoma vulvar es un tumor benigno poco frecuente con muy pocos casos descritos en la literatura. Por lo general, se diagnostica entre los 20 y 70 años. Tiene un buen pronóstico y rara vez recurre después de la escisión. Presentamos un caso de fibroadenoma vulvar, en una mujer de 33 años, manifestado como un tumor localizado, bien definido de partes blandas en el labio mayor izquierdo. La lesión fue extirpada completamente y la histología confirmó un fibroadenoma con marcador de estrógeno positivo.


ABSTRACT Vulvar fibroadenoma is a rare benign tumor with few cases reported in the literature. It usually occurs between 20 and 70 years of age. It has a good prognosis and rarely recurs following excision. We present a case of vulvar fibroadenoma as a localized, well-defined soft tissue mass in the left labium majus of a 33-year-old woman. The mass was excised completely, and histology demonstrated a fibroadenoma positive for estrogen receptor.

ABSTRACT

RESUMEN Existen pocos estudios que describan las complicaciones neuromusculares del hipertiroidismo. Presentamos el caso de una mujer de 36 años con antecedente de enfermedad de Graves en manejo médico, quien presentó compromiso motor y sensitivo progresivo en extremidades inferiores hasta comprometer la marcha. La electromiografía fue compatible con polineuropatía desmielinizante aguda, la resonancia nuclear magnética sugirió síndrome de Guillain-Barré. Se proporcionó manejo con plasmaféresis y se ajustó tratamiento tiroideo presentando mejoría transitoria. Posteriormente presentó deterioro neurológico con debilidad ascendente y compromiso deglutorio; a pesar de inicio de ciclo de inmunoglobulina persistió empeoramiento clínico con requerimiento de soporte ventilatorio; se decidió realizar tiroidectomía, que resultó en mejoría clínica y resolución del cuadro.


ABSTRACT There are few studies that describe the neuromuscular complications of hyperthyroidism. We present the case of a 36-year-old woman with a history of Graves' disease in medical management, who presented motor and sensitive involvement in the lower limbs until compromising gait. Electromyography was compatible with acute demyelinating polyneuropathy, nuclear magnetic resonance suggested Guillain-Barré syndrome. Management with plasmapheresis was indicated, and thyroid therapy was adjusted with transient improvement. Subsequently, she presented neurological deterioration with ascending weakness and swallowing compromise; despite an immunoglobulin cycle regimen, clinical worsening persisted with the requirement of ventilatory support; thyroidectomy was performed resulting in clinical improvement and resolution of the condition.

ABSTRACT

Background: The Diabetes Mellitus 2 treatment adherence scale version III (EATDM-III) was devised in Costa Rica. Its seven factors are family support, community organization and support, physical exercise, medical control, hygiene and self-care and assessment of physical condition. Aim: To assess the psychometric properties of the scale in Chilean patients. Material and Methods: The results of the EATDM-III scale, applied to 274 patients with Diabetes Mellitus 2 aged 59 ± 11 years (59% women), were analyzed. Reliability, item, exploratory and confirmatory factorial analyses were carried out both in the initial and the proposed model. Results: We propose a version of 30 items grouped in six dimensions, improving the fit indices obtained with the original scale. The review of item factor loadings shows that all are appropriate both in magnitude and statistical significance, with values between 0.46 and 0.93. Internal consistency measured by Cronbach s alpha, was 0.85 for the total scale. Conclusions: The adapted EATDM-III scale is reliable and can be used to assess treatment adherence in Chilean patients.

ABSTRACT

Aim: Case report of association between diastematomyelia and medulloepithelioma. Method: 14-year-old patient with lower back pain and recent neurological deficit in extremities. CT and MRI scans of the thoracolumbar spine revealed a diastematomyelia. Intraoperative examination confirmed the presence of a spinal dysraphism and associated tumor, which was almost completely resected. Result: Histopathological and immunohistochemical findings were consistent with medulloepithelioma. Her postoperative course was uneventful. Conclusion: Diastematomyelia may manifest during adolescence as lower back pain and neurological deficit. The association of this malformation with a neoplasia is extremely rare; the present case describes concomitance with medulloepithelioma.

ABSTRACT

Introducción: Para el sistema endocrino la neoplasia más frecuente es el cáncer diferenciado de tiroides, con un claro incremento en su incidencia. Es importante encontrar asociaciones que posteriormente permitan establecer factores de riesgo y/o protectores claves en la estrategia terapéutica futura. Por lo que se investigó la relación entre la presencia de tiroiditis linfocítica con la gravedad y persistencia/recurrencia del carcinoma diferenciado de tiroides Materiales y métodos: se hizo un estudio comparativo a través de una serie de casos de carcinoma diferenciado de tiroides llevados a cirugía entre enero de 1997 y diciembre de 2012 en una clínica especializada de nivel IV ubicada en Bogotá, Colombia. Se evaluó la asociación entre la presencia de factores clínico-patológicos y la presencia de persistencia/recurrencia usando pruebas de asociación chi cuadrado y odds ratios. Para evaluar la presencia de asociación a nivel multivariado se utilizaron modelos de regresión binaria con enlace log log complementario. Resultados: no se observó asociación estadística entre presencia de tiroiditis linfocítica y la presencia de variables de severidad clínico-patológica. Sin embargo, fue posible evidenciar asociación entre tiroiditis linfocítica con persistencia/recurrencia en presencia invasión vascular (OR 6,6 IC95% 1,4-32), invasión linfática (OR 5,4 IC95% 1,3-22,1) y compromiso ganglionar en el vaciamiento lateral (OR 58 IC95% 7,1-476) independiente de la edad y el sexo. Conclusión: Es posible que la tiroiditis linfocítica no se relacione con la presencia de marcadores de severidad clínico-patológica pero sí con una mayor persistencia/recurrencia de la enfermedad. Rev Argent Endocrinol Metab 51:169-177, 2014 Los autores declaran no poseer conflictos de interés.


Introduction: Differentiated thyroid cancer is the most common malignancy and it shows an increased incidence. It is important to find associations that may allow for identification of key risk and/or protective factors for the development of future therapeutic strategies. Thus, we investigated the relationship between the presence of lymphocytic thyroiditis with severity and persistence / recurrence. Materials and methods: We conducted a comparative study using data from patients with differentiated thyroid carcinoma who had undergone total or partial thyroidectomy between January 1997 and December 2012 at a Level IV specialized institution located in Bogotá, Colombia. We evaluated the association between the presence of clinical and pathological factors and the presence of persistence/recurrence using chi-square tests and OR. For multivariate analysis a binary regression model with complementary log-log link was used. Results: No statistically significant relationship was observed between lymphocytic thyroiditis and the presence of clinical-pathological severity factors. However, lymphocytic thyroiditis was associated with persistence / recurrence in the presence of vascular invasion (OR 6.6 95 % CI 1.4-32), lymphatic invasion (OR 5.4 95 % CI 1.3-22.1) and positive lateral neck nodes (OR 58 95 % CI 7.1-476), independently of gender and age. Conclusion: Lymphocytic thyroiditis may not be associated with the presence of markers of clinical-pathological factors but it is effectively associated with a higher persistence/recurrence of disease. Argent Endocrinol Metab 51:169-177, 2014 No financial conflicts of interest exist.

ABSTRACT

Las calcificaciones cerebrales agrupan diversas entidades patológicas que frecuentemente han sido referidas como enfermedad de Fahr. Estas tienen una presentación clínica variada, desde el curso subclínico hasta manifestaciones motoras convulsivas e inclusive demenciales. Se presenta el caso de una mujer de 46 años con una crisis epiléptica convulsiva generalizada, asociada a calcificaciones difusas por hipoparatiroidismo postquirúrgico, en quien se inicia reposición de calcio, logrando resolución del cuadro convulsivo. Este reporte destaca el abordaje fisiopatológico de las calcificaciones cerebrales por hipoparatiroidismo, la importancia de una definición más general de cómo sería el síndrome de calcificación cerebral teniendo en cuenta las diferentes entidades patológicas conocidas asociadas con diferente espectro clínico y, por último, pone en evidencia la carencia de investigaciones sobre el tema.


Brain calcifications group diverse pathological entities that have often been referred to as Fahr disease. These have a clinical presentation which varies from subclinical course to several motor manifestations and dementia. We report the case of a 46 year old woman with generalized seizures associated with diffuse calcifications on postoperative hypoparathyroidism in whom calcium supplementation starts achieving resolution of the symptoms. This report highlights the pathophysiological approach by hypoparathyroidism brain calcifications, the importance of a general definition as in the brain calcification syndrome considering different known disease entities associated with different clinical spectrum and, finally, demonstrates the lack of research on the subject.

ABSTRACT

Objective: to evaluate a barium study of the upper gastrointestinal tract in early postoperative monitoring of bariatric surgery patients, recording the anatomical characteristics of the gastric remnant and the frequency of complications such as leakage of contrast and emptying difficulties. Materials and Methods: we retrospectively evaluated the barium study of the upper gastrointestinal tract performed in 168 patients after gastric bypass (GBP) and 98 patients after vertical subtotal gastrectomy (VSG). All evaluated examinations were performed in the first five days after surgery. Gastric remnant volume was registered in relation to the T12 vertebral body (only in GBP), the presence and site of contrast leakage and gastric remnant emptying difficulties. Results: the average age of patients undergoing GBP was 43 years, and 37 years for VSG. The average volume of gastric remnant of patients with GBP was 1.5 T12 vertebral bodies. Two GBP operated patients (1.2 percent) had leakage of the contrast medium at the level of the gastroenteric anastomosis; in VSG operated patients the contrast leakage occurred in 7 cases (7.1 percent), the most frequent site being the left side cephalic portion of the gastric remnant. All cases with contrast leakage were subsequently studied using computed tomography, finding the presence of wound dehiscence or fluid collections adjacent to the gastric remnant. Emptying difficulty was observed in 12 patients operated for GBP (7.1 percent); there was no record of this complication in patients undergoing VSG. Conclusion: the upper gastrointestinal barium study is useful in patients after bariatric surgery to assess the early postoperative anatomy and volume of the gastric remnant, as well as to detect possible complications. It is a simple test, which should be applied as a routine control in these patients.


Objetivo: evaluar el estudio baritado del tubo digestivo alto en el control postoperatorio precoz de pacientes operados de cirugía bariátrica, registrando las características anatómicas del remanente gástrico y la frecuencia de complicaciones como filtración del medio de contraste y dificultad al vaciamiento. Materiales y método: se evaluó retrospectivamente el estudio baritado del tubo digestivo alto realizado en 168 pacientes postoperados de bypass gástrico (BPG) y 98 pacientes postoperados de gastrectomía subtotal vertical (GSV). Todos los exámenes evaluados fueron realizados en los primeros cinco días postcirugía. Se registró volumen del remanente gástrico en relación al cuerpo vertebral T12 (sólo en BPG), presencia y sitio de filtración del medio de contraste y dificultad al vaciamiento del remanente gástrico. Resultados. La edad promedio de los pacientes sometidos a BPG fue de 43 años y GSV 37 años. El volumen promedio del remanente gástrico de los pacientes con BPG fue 1,5 cuerpos vertebrales T12. Dos pacientes operados de BPG (1,2 por ciento) presentaron filtración de medio de contraste a nivel de la anastomosis gastro-enteral; en los pacientes operados de GSV la filtración del medio de contraste ocurrió en 7 casos (7,1 por ciento), siendo el sitio más frecuente la porción cefálica lateral izquierda del remanente gástrico. Todos los casos de filtración de medio de contraste fueron posteriormente estudiados con tomografía computada, comprobándose la presencia de dehiscencia de la sutura o bien colecciones líquidas adyacentes al remanente gástrico. Se observó dificultad al vaciamiento en 12 pacientes operados de BPG (7,1 por ciento); no se registró esta complicación en los pacientes operados de GSV. Conclusión: el estudio baritado del tubo digestivo alto es útil en pacientes postoperados de cirugía bariátrica para conocer la anatomía y el volumen del remanente gástrico en el postoperatorio precoz, así como también para detectar posibles complicaciones...

ABSTRACT

Objetivo: Entre las moléculas orgánicas que componen la saliva se han descrito un gran número de proteínas. No existe evidencia suficiente que permita especular sobre los cambios en el contenido proteico salival asociados al envejecimiento normal. El objetivo fue determinar si existen diferencias en la concentración total de proteínas en saliva de adultos y adultos mayores. Método: Se obtuvieron muestras de saliva estimulada y no estimulada de individuos pertenecientes a dos grupos etarios, adultos (A) (n=30) (edad promedio: 25 años) y adultos mayores (AM) (n=30) (edad promedio: 68 años). Se excluyeron aquellos sujetos que presentaron alguna patología oral/sistémica o consumo de fármacos/sustancias relacionados con alteraciones del flujo o composición salival. Cada muestra fue centrifugada. A 10 ul del sobrenadante se agregaron 190 ul de solución de Bradford. Se realizó el recuento mediante lectura con espectrofotómetro (595 nm). La concentración de proteínas fue comparada entre los grupos en estudio utilizando la prueba t de Student (p<0.05). Resultados: La concentración de proteínas totales de saliva no estimulada fue mayor en AM (5.5+/-2.6 ug/ul) que en A (3.2+/-1.7 ug/ul) (p<0.05). La concentración de proteínas totales de saliva estimulada fue mayor en AM (4.9+/-0.4 ug/ul) que en A (4.0+/-0.3 ug/ul) (p<0.05). Conclusión: La concentración de proteínas en saliva aumenta en adultos mayores. Se requieren nuevos estudios para caracterizar estos cambios salivales con la edad.


Objective: A high number of proteins has been described in saliva. Scarce evidence allows to speculate about the variations on protein content associated with aging. The aim was to determine if there is a difference in total protein concentration between adults and older adults. Methods: Samples were collected from unstimulated and stimulated saliva of individuals from two age groups, adults (A) (n=30) (mean age 25 years) and older adults (OA) (n=30)(mean age: 68 years). Subjects with oral/systemic diseases or consuming medications that alter salivary flow were excluded from the study. Each sample was centrifuged and 10 ul of the supernatant was added to 190 ul of Bradford solution. Protein concentration was obtained by spectrophotometry (595 nm) Protein concentration was compared between the groups using student’s t test (p<0.05). Results: Total protein concentration from unstimulated saliva was higher in OA (5.5+/-2.6 ug/ul) than in A (3.2 +/- 1.7 ug/ul) (p<0.05). Total protein concentration of stimulated saliva was higher in OA (4.9+/-0.4 ug/ul) than in A (4.0+/-0.3 ug/ul) (p<0.05). Conclusion: Salivary protein concentration increases in older adults. Further studies are suggested to characterize these changes.

ABSTRACT

Velocardiofacial syndrome (VCFS) is due to a microdeletion on chromosome region 22q11.2. Clinically, it is characterized by congenital anomalies and psychiatric and cognitive manifestations. The most common structural defects are congenital heart disease and palatal anomalies, both due to abnormal development of the pharyngeal pouches. Another less studied manifestation is abdominal wall hernias. Objective: To characterize the frequency and types of hernias in patients with VCFS, and their association with congenital cardiopathies and palatine abnormalities. Patients and Methods: 202 patients were evaluated by direct clinical examination and questionnaire about their phenotypic characteristics. Results were compared to those found in the literature. Results: Age range was 0.5 to 48.4 years old (mean 11.9 years), 50.4 percent were females. Twenty two percent of patients had abdominal wall hernias. Of these, 49.1 percent were inguinal and 40.3 percent, umbilical. Conclusion: Patients with VCFS have a higher incidence of abdominal hernias than general population, described as approximately 5 percent. This is another common manifestation of the syndrome, not attributable to defects in development of pharyngeal pouches and with unknown pathogenesis.


El síndrome velocardiofacial (SVCF) se debe a una microdeleción en la región cromosómica 22q11.2. Clínicamente, se caracteriza por anomalías congénitas y manifestaciones siquiátricas y cognitivas. Entre las malformaciones más comunes, están las cardiopatías congénitas y anomalías palatinas, por defectos en el desarrollo de las bolsas faríngeas. Otra manifestación menos estudiada son las hernias de la pared abdominal. Objetivo: Caracterizar la frecuencia y tipos de hernias en pacientes con SVCF y su asociación con cardiopatías congénitas y anomalías del paladar. Pacientes y Método: Evaluamos 202 pacientes mediante un examen clínico directo y un cuestionario sobre sus características fenotípicas. Comparamos los resultados con la información de la literatura. Resultados: El rango de edad fue de 0,5 a 48,4 años (media de 11,9 años), 50,4 por ciento de sexo femenino. El 22 por ciento de los pacientes presentó hernias de la pared abdominal. De estas, el 49,1 por ciento fueron inguinales y el 40,3 por ciento, umbilicales. La frecuencia de hernias en los pacientes con SVCF es significativamente mayor que la descrita para la población general, aproximadamente un 5 por ciento. Esta es una manifestación común del síndrome, que no es atribuible a defectos del desarrollo de las bolsas faríngeas y cuya patogenia no ha sido definida.

ABSTRACT

Introduction: Oral cancer is a common disease in many parts of the world, in Chile only accounts for 1.6 percent of all cancers. The majority is squamous cell carcinoma with important clinical, epidemiological and pathological differences between lip, oral and orofaringeal locations. Objective: To analyze clinical and pathological characteristics of oral and oropharingeal squamous cell carcinoma in Temuco, Chile. Materials and Methods: A descriptive, retrospective study of all diagnosed cases in 15 years (1994 and 2008). The patients were analyzed according to gender, age; and the tumors were classified based on anatomic location, size, macroscopical findings and degree of differentiation. Results: We found 93 carcinomas, with male to female ratio of 5:1, average age 67 years. Patients under 50 years accounted for only 8 percent of cases. The most common sites were lower lip, tongue and gingiva, with an average size of 28 mm, which increased towards orofarinx and more than half were moderately differentiated. Conclusions: In our region, this carcinoma most often affects the seventh decade of life and male population and has similar characteristics to those in other countries which is predominantly. The size at diagnosis is significant. The detection of some differences in the group with mapuche surnames warrants a study with a larger number of cases.


Introducción: El cáncer oral es una enfermedad frecuente en muchas partes del mundo, en Chile corresponde al 1,6 por ciento del total de cánceres. La gran mayoría corresponde a carcinoma epidermoide, con importantes diferencias clínicas, epidemiológicas y patológicas entre las localizaciones labial, intraoral y orofaríngea. Objetivo: Analizar las características clínicas y patológicas del carcinoma epidermoide oral y orofaríngeo en Temuco, Chile. Material y Método: Estudio descriptivo, retrospectivo de todos los casos diagnosticados en 15 años (1994 y 2008), en el Hospital Regional de Temuco. Los pacientes fueron analizados de acuerdo a género, edad, y los tumores fueron clasificados basados en su localización anatómica, tamaño, características macroscópicas y grado de diferenciación. Resultados: Se encontraron 93 carcinomas, con relación hombre:mujer de 5:1, edad promedio 67 años. Pacientes menores a 50 años correspondían sólo al 8 por ciento de los casos. Las localizaciones más frecuentes fueron labio inferior, lengua y encía, con un tamaño promedio de 28 mm, el que aumentó hacia la orofarinx, más de la mitad eran moderadamente diferenciados. Conclusiones: En nuestra región, este carcinoma afecta con mayor frecuencia a la séptima década de la vida y a población masculina y posee características similares a las descritas en otros países donde predomina la raza blanca. El tamaño al diagnóstico es considerable. La detección de algunas diferencias en el grupo con apellidos mapuches amerita un estudio con un mayor número de casos.

ABSTRACT

Background: Gleason pathological score in prostate cancer is an importantprognostic indicator. However, the concordance between the score of trans rectal needle biopsies and the final score of the surgical piece may be variable. Aim: To analyze the concordance between Gleason scores of trans rectal prostate biopsies and those of the surgical piece obtained after prostatectomy. Material and Methods: Retrospective analysis of 168 pathological records of radical prostatectomies, performed between 1993 and 2009. All these patients had also a trans rectal biopsy performed previously. Patients with less than 12 tissue cylinders obtained during the trans rectal biopsy or incomplete data were not included in this analysis. Results: Sixty eight percent of trans rectal biopsies had Gleason scores that were concordant with those of the surgical piece. The score was higher or lower in 27 and 10 percent of biopsies, respectively. Conclusions: Gleason scores of trans rectal biopsies and those of the surgical piece were concordant in 68 percent of cases in this series of pathological records.

ABSTRACT

The relationship between human papillomavirus (HPV) and uterine cervical cancer (UCC) is widely known and accepted. Aim: To determine the frequency of genotypes of HPV in cervical preneoplastic lesions in a high risk area of UCC. Material and Methods: Using a combination of PCR and Reverse Line Blot technique, 235 formalin fixed paraffin embedded samples, with diagnosis of low-grade squamous intraepithelial lesion (LSIL) or high-grade squamous intraepithelial lesion (HSIL) were genotyped. Results: HPV was detected in 61.2 percent of LSIL and 78.1 percent of HSIL. The main genotypes found were HPV 16, 18, 31, 45, 56 y 58. HPV 16 was the most common in both LSIL (18.1 percent) and HSIL (36.9 percent). HPV 16 or 18 were present in 25.1 percent and 47.1 percent of the LSIL and HSIL respectively. In both LSIL and HSIL, the predominant viral genotypes were those types classified as with a high oncogenic risk. Conclusions: HPV genotypes 16, 18, 31, 45, 56 y 58 were the most common in our series. HPV 16 and 18, viral types with high oncogenic risk and included in commercial vaccines, were found in 25.1 percent and 47.1 percent of LSIL and HSIL, respectively.

ABSTRACT

Introducción: El síndrome cardiopulmonar por hantavirus (SCPH) es una enfermedad infecciosa aguda, caracterizada por insuficiencia cardio-respiratoria súbita y alta mortalidad, causada por un virus ARN del género Hantavirus, familia Bunyaviridae. Un 15 por ciento de los casos chilenos ha sido pesquisado en la Araucanía. Objetivo: Conocer en casos fatales de SCPH, sus características clínicas y morfológicas. Material y Método: Estudio descriptivo-retrospectivo de siete casos fatales con examen postmortem, de SCPH, atendidos entre 1997 y 2009 en el Hospital Regional de Temuco. Resultados: Los casos fueron principalmente pacientes jóvenes, rurales, con un cuadro de compromiso respiratorio progresivo, con leucocitosis, trombopenia e infiltrado pulmonar intersticial bilateral. Los principales hallazgos histopatológicos fueron un acentuado edema pulmonar intra-alveolar e intersticial, con escaso daño epitelial e infiltrado mono-nuclear y leve edema miocárdico con infiltrado mononu-clear. Conclusiones: Los antecedentes epidemiológicos, clínicos y laboratorio permiten sospechar SCPH. En los casos fatales la autopsia permite diferenciar el SCPH de otras patologías similares y aporta tejidos para confirmar el diagnóstico.


Introduction: Hantavirus cardiopulmonary syndrome (HCPS) is an acute infectious disease characterized by sudden cardiorespiratory failure and high mortality, caused by a RNA virus of the genus Hantavirus, family Bunyaviridae, 15 percent of Chilean cases have been detected in the Araucania Region. Objective: To determine in fatal cases of HCPS, clinical and morphological characteristics. Materials and Methods: Descriptive-retrospective analysis of seven fatal cases with postmortem study of HCPS, attended between 1997 and 2009 at the Hospital of Temuco, Chile. Results: Cases were young patients from rural areas, and presented as an illness of progressive respiratory failure, with leukocytosis, thrombocytopenia and bilateral interstitial pulmonary infiltrates. Main morphological findings were marked intersticial and intraalveolar pulmonary edema, with minimal epithelial injury and mononuclear cell intersticial infiltrate and mild edematous intersticial inflamatory process. Conclusions: Epidemiological, clinical and laboratory background allow to suspect HCPS. In fatal cases, the autopsy makes possible to discard other similar pathologies and provide tissue for confirmation of the disease.

ABSTRACT

El virus papiloma humano (VPH) es el principal factor causal del cáncer cervicouterino (CCU). Así, detectar y genotipificar el VPH es importante para conocer la frecuencia de los genotipos presentes en la región. En este trabajo se estudiaron 44 biopsias de adenocarcinoma cervical (ACC). Para la detección del VPH se empleó una reacción de polimerasa en cadena anidada dirigida al gen L1 (RPCL1), para la genotipificación viral se utilizaron enzimas de restricción (Rsa I, Dde I, Pst I) y secuenciación. Se detectó ADN viral mediante RPCL1 anidada en 100 por ciento de las biopias. Se logró tipificar 38/44 casos: 81,6 por ciento VPH 16; 13,2 por ciento VPH 18; 2,6 por ciento VPH 33 y 2,6 por ciento VPH 18/33. Conclusiones: La metodología fue exitosa para identificar el tipo viral en 86 por ciento de las biopsias. Se observó una estrecha asociación ACC-VPH, especialmente con el tipo viral 16, detectado en 81,6 por ciento de los casos tipificados.


Human papillomavirus (HPV) is the main cause of cervical cancer. Thus, HPV detection and typing becomes important in order to know the frequency of genotypes present in the region. In this paper we studied 44 biopsies of cervical adenocarcinoma. For HPV detection nested polymerase chain reaction (PCR) was used to amplify the L1 gene. For viral typing restriction enzymes (Rsa I, Dde I, Pst I) and DNA sequencing were used. Viral DNA was detected by nested L1 PCR in 100 percent of biopsies; 38/44 cases could be typed: 81.6 percent HPV16; 13.2 percent HPV 18; 2.6 percent VPH 33 and 2.6 percent HPV 18/33. Conclusions: The technique was successful in identifying the virus type in 86 percent of biopsies. There was a strong association ACC-HPV, especially with the viral type 16, detected in 81.6 percent of established cases.
