The Abductor Pollicis Longus Tendon as an Alternative Graft in Hand Surgery.

Initial treatment of damaged tendons after soft tissue trauma of the hand can be performed with primary tendon reconstruction or with tendon grafts if indicated. The most frequently used tendons are from the palmaris longus and plantaris muscles. Nonetheless, these muscles may not be present or their anatomic characteristics might not suitable for reconstructive procedures. Here, we present an alternative surgical technique for tendon reconstruction of the hand using abductor pollicis longus accessory tendons as grafts. The abductor pollicis longus can be considered an excellent choice of graft for tendon reconstruction of the hand because of its multiple bellies, ease of extraction, and limited donor site morbidity and the frequent absence of the palmaris longus tendon.

Calf's sex, parity and the hour of harvest after calving affect colostrum quality of dairy cows grazing under high tropical conditions.

High-quality colostrum is an important factor influencing neonatal calf health, and quality assessment is essential to obtain good health results. This research evaluated the effects of the calf's sex, the parity of the cow and the hour of colostrum harvest after parity on the fat, nonfat solids, protein and Ig contents in Holstein colostrum for cows under high grazing conditions in the tropics. The effects of the calf's sex and parity on somatic cell count (SCC) at the first milking postpartum were determined. A comparison was made between a laboratory method and a farm method for the estimation of the fat and protein content of colostrum. Thirty-three cows were sampled in the study. The calf's sex was shown to have an effect on the amount of colostrum, on the concentration of fat, and on the amount of milk produced by lactating Holstein cows; all were higher in cows that gave birth to a female calf. Colostrum protein decreased after the first hour postpartum, and the Ig concentration had a tendency to decrease after 4 h. The cows that had parity 1-2 had lower Ig concentrations and total production of Igs, and higher SCC at the first milking postpartum. Ekomilk was a reliable method to measure the colostrum fat on the farm.

Dry food affects the oxidative/antioxidant profile of dogs.

BACKGROUND: Including adequate concentrations of antioxidants in dog diets has been recommended to reduce their vulnerability to the action of free radicals and reactive oxygen species (ROS). Oxidative stress in dogs has been associated with a wide range of diseases and disorders, as well as with ageing. There are few reports about the influence of diet on dog's antioxidant profile and oxidative stress. OBJECTIVE: The objective of this study was to evaluate the effect of four types of dry dog food on the oxidative/antioxidant profile of dogs. METHODS: Six Beagle dog males were used. The study included four experimental diets (dry foods A-D). Each dry food was supplied for 5 weeks to all dogs, for a total of 24 weeks, including an adaptation week between one food and another. For each dry dog food, the total phenolic content (TPC), total antioxidant capacity (TAC) and cytotoxicity were evaluated. Each week, a blood sample was collected to measure ROS and TAC of plasma. A crossover repeated measures design was used. Mixed models were adjusted, and means were compared using the Tukey test. RESULTS: Food A had the highest values for TPC and TAC. Food C had the lowest levels of ROS, whereas food B had the highest TAC in the blood plasma. The dog had a significant influence on the redox state of its blood plasma, even when the same dog was fed the different dry foods. CONCLUSION: Dry dog food influences the oxidative/antioxidant profile of dog's blood plasma; however, this seems to be unrelated to the antioxidant profile of the food.

Merkel cell carcinoma in the hand. Report of two cases.

Merkel-cell-carcinoma of the hand is rare. The Pathological and Immunohistochemical diagnosis helps us to focus the treatment. Immunotherapy has shown beneficial effects in unresectable/advanced/metastatic stages. The quantification of antibodies against Merkel-cell-polyomavirus (MCPyV) can be a useful for prognosis and follow-up. A wide margin in surgery and the sentinel node are the first option with Radiotherapy.

Prevalence of the risk of depression and worry in pregnant women in the context of the COVID-19 pandemic in Antioquia, Colombia, 2020-2021 / Prevalencia del riesgo de depresión y preocupaciones en mujeres gestantes en el contexto de la pandemia por COVID-19 en Antioquia, Colombia, 2020-2021

Objectives: To describe the prevalence of symptoms of depression and worry affecting pregnant women during the COVID-19 pandemic. Material and methods: Descriptive crosssectional study that included pregnant women with access to a technological device (mobile phone, computer or tablet) and Internet connection, living in Antioquia, Colombia. Women with literary and technological illiteracy were excluded. An online survey was conducted to gather information about sociodemographic and baseline clinical conditions and the main concerns caused by the pandemic. Additionally, the Edinburg Depression Scale (EPDS) was applied in order to measure the risk of depression. The Jamovi software was used for data processing and statistical analysis. Results: Overall, 345 pregnant women between 15 and 44 years of age were surveyed, with the finding of a 30.4 % prevalence of the risk of depression. Domestic violence and absence of a support network were identified in 4.9 % and 8.4 % of cases. The major sources of worry were the fear of being separated from their babies on the day of birth, the possibility of having to be alone during childbirth, and the fear of contagion due to potential effects on the fetus or the newborn. Conclusions: Depression symptoms have been frequent among pregnant women during the COVID-19 pandemic. It is important to inquire about stress factors and depression symptoms during prenatal visits, childbirth and the postpartum period. Additional local studies are needed to assess other mental health disorders that may have increased during the COVID-19 pandemic.

Objetivos: describir la prevalencia de los síntomas de depresión y las preocupaciones que afectaron a las gestantes durante la pandemia por COVID-19. Materiales y métodos: estudio transversal descriptivo, se incluyeron mujeres gestantes, con acceso a un medio tecnológico (celular, computador o tableta) y conectividad a internet, residentes en Antioquia, Colombia. Se excluyeron mujeres con analfabetismo literario y tecnológico. Se encuestaron, en línea, las condiciones sociodemográficas y clínicas basales y las principales preocupaciones generadas por la pandemia, además se aplicó la Escala de Depresión de Edimburgo (EPDS) para medir el riesgo de depresión. Se usó el software Jamovi para el procesamiento y análisis estadístico. Resultados: se encuestaron 345 mujeres gestantes de 15 a 44 años, se identificó una prevalencia de riesgo de depresión en 30,4 % de las mujeres encuestadas. Se identificó violencia intrafamiliar en el 4,9 % y ausencia de red de apoyo en el 8,4 %. Se encontraron como mayores preocupaciones temor a ser separadas del bebé el día del parto, la posibilidad de no tener acompañante durante el parto, y temor al contagio por los efectos en el bebé in útero o en el recién nacido. Conclusiones: los síntomas de depresión han sido frecuentes en las mujeres gestantes durante la pandemia del COVID-19. Es importante averiguar por factores de estrés y síntomas de depresión en el control prenatal, el parto y el postparto. Se requieren nuevos estudios locales que evalúen otros trastornos de salud mental que se hayan podido incrementar durante la pandemia por COVID-19.

Verrucous psoriasis in a male patient with a history of vulgar psoriasis: Case report and literature review / Psoriasis verrugosa en un hombre con antecedentes de psoriasis en placa, reporte de caso y revisión de la literatura

Verrucous psoriasis is an atypical and rare variant of psoriasis, with few cases reported in the literature, characterized by the presence of simetric hypertrofic and verrucous plaques on the limbs and trunk. We present the case of a 63 year old male patient with a history of vulgar psoriasis 20 years ago, in treatment with topical steroids, who has been presenting for 10 years a verrucous plaque in the distal third of the posterior aspect of the leg. Biopsy of the lesión is performed with a diagnostic impression of squamous cell carcinoma (verrucous), but the histopathologic study shows compatible changes with a verrucous psoriasis, ruling out the presence of malignancy

La psoriasis verrugosa es una variante atípica y poco frecuente de la psoriasis, con pocos casos reportados en la literatura. Se caracteriza por la presencia de placas hipertróficas y verrugosas simétricas en extremidades y tronco. Se presenta el caso de un paciente de 63 años con diagnóstico de psoriasis en placa 20 años atrás, tratado con esteroide tópico y quien 10 años antes había desarrollado una placa de aspecto verrugoso en el tercio distal de la cara posterior de la pierna izquierda. Se tomó la biopsia de la lesión por sospecha de un carcinoma escamocelular (verrugoso). El estudio histopatológico mostró cambios indicativos de psoriasis verrugosa y descartó la presencia de malignidad.

Prevalencia etiológica de infección del tracto urinario en gestantes sintomáticas, en un hospital de alta complejidad de Medellín, Colombia, 2013-2015 / Etiological prevalence of urinary tract infections in symptomatic pregnant women in a high complexity hospital in Medellín, Colombia, 2013-2015

Objective: To determine the prevalence of urinary tract infections (UTIs), the microbiological profile and antibiotic resistance in pregnant women with suspected urinary tract infection. Materials and methods: Cross-sectional study of pregnant women with suspected community- acquired urinary tract infection referred to the outpatient clinic by prenatal care practitioners or seen in the emergency room, and hospitalized be- tween August 2013 and September 2015 in a referral teaching hospital located in Medellin, Colombia. Pregnant women who had received antibiotics on the day before admission were excluded. Random sampling. Measured variables: sociodemographic, clinical and bacteriological. Descriptive statistics were applied. Results: The prevalence of urinary tract infections was 29%. Gram negative bacteria isolates were found predominantly, the main ones being E. coli and K. pneumoniae at 57.7 and 11.4%, respectively. Resistance to trimethoprim- sulfamethoxazole and to ampicillin-sulbactam was observed in 19.5% and 17.5% of isolates, respectively. Conclusions: Population-based studies are needed to provide a better approach to bacterial resistance in community-acquired UTIs. On the other hand, the high resistance observed may suggest that some of the exposed antibiotics might not be included in the local guidelines for the management of UTIs.

Objetivo: Determinar la prevalencia de infección del tracto urinario (ITU), el perfil microbiológico y la resistencia a los antibióticos en mujeres gestantes con sospecha de infección del tracto urinario. Materiales y métodos: Estudio de corte transversal. Ingresaron gestantes con sospecha de infección del tracto urinario adquirida en la comunidad, remitidas a consulta externa desde su control prenatal o atención por urgencias, y hospitalizadas entre agosto de 2013 y septiembre de 2015 en un hospital universitario de referencia ubicado en Medellín, Colombia. Se excluyeron gestantes que hubieran recibido antibióticos el día anterior a la admisión. Muestreo aleatorio simple. Variables medidas: sociodemográficas, clínicas y bacteriológicos. Se aplicó estadística descriptiva. Resultados: La prevalencia de infección del tracto urinario fue del 29 %. Predominaron los aislamientos de bacterias Gram negativas, principalmente E. coli y K. pneumoniae en un 57,7 y 11,4 % respectivamente. Se observó resistencia a trimetoprim- sulfametoxazol en el 19,5 % y ampicilina-sulbactam en el 17,5 % de los aislamientos. Conclusiones: Se requieren estudios de base poblacional para una mejor aproximación a la resistencia de las bacterias causantes de la ITU en la comunidad. Por otra parte, la alta resistencia observada podría sugerir que algunos antibióticos expuestos no sean incluidos en las guías locales de manejo de la ITU.

Clinical, sociodemographic, pharmacological and quality of life characterization of patients with a diagnosis of moderate to severe psoriasis treated in a specialized psoriasis clinic / Caracterización clínica, sociodemográfica, farmacológica y calidad de vida de pacientes con diagnóstico de psoriasis moderada a severa atendidos en una clínica especializada en psoriasis

Abstract Introduction: psoriasis is a systemic, inflammatory, and chronic disease with a global prevalence between 0.6-6.5 %. It is related to multiple comorbidities and generates a significant decrease in quality of life. Objective: to characterize sociodemographic, clinical, pharmacological, and quality of life variables in a population of patients with moderate-severe psoriasis. Methods: descriptive observational study the patients with a diagnosis of severe-moderate psoriasis treated in the Clínica Integral de Psoriasis-CLIPSO between May 2018 - June 2020. A collection format was designed for defined variables and a univariate analysis was performed. Results: 948 patients were identified with a median age of 50 years (IQR: 38-60) of which 51.0 % were women. 23.6 % were incidents with a median treatment time of 114 days (IQR: 98-127) and 73.9 % were prevalent with a median treatment time of 228 days (IQR: 160-371). The type of therapy used was mainly non-biological systemic and 90.9 % of the patients were adherent to the treatment. The clinical variables were similar for both groups and the most common phenotype was psoriasis vulgaris (57.1 %). The health-related quality of life in both groups was greater than 60 points and the affected dimensions were physical and psychological health. 27.3 % of the patients had comorbidities associated with cardiovascular risk and 44.7 % were overweight. Conclusion: knowing the sociodemographic, clinical, pharmacological, and quality of life characteristics of patients with moderate-severe psoriasis allows the identification of risk factors and comprehensive management of the disease.

Enfermedad celiaca en niños / Celiac disease in children

La enfermedad celíaca (EC) es una enteropatía autoinmune desencadenada por la ingesta de fracciones de gliadina presente en el gluten y proteínas similares del centeno y la cebada, en individuos predispuestos genéticamente. Por muchos años, la EC fue subdiagnosticada; sin embargo, dado el mayor conocimiento en su forma de presentación, junto a los nuevos test serológicos, hoy se sabe que la EC es una patología relativamente común. A pesar de que la EC puede manifestarse a cualquier edad, con un amplio espectro clínico que puede afectar cualquier órgano, los casos típicos se manifiestan en la infancia. Esta revisión pretende agrupar el conocimiento más significativo que actualmente se tiene sobre esta enfermedad.

Celiac disease (CD) is an autoimmune enteropathy triggered by ingestion of the gluten fraction of wheat proteins and similar alcohol-soluble proteins of barley and rye in genetically susceptible subjects. For many years, celiac disease has been under diagnosed. However, because of today’s greater knowledge of its presentations and the availability of new more accurate serologic tests, it is now known that CD is relatively common. Although CD can occur at any age, with a broad clinical spectrum affecting any organ, typical cases often manifest in infancy. This review aims to bring together the most significant current knowledge about this disease.

Quilopericardio secundario a cirugía cardiovascular / Chylopericardium secondary to cardiovascular surgery

El quilopericardio constituye una complicación rara de la cirugía de defectos cardíacos congénitos. Es causada por la obstrucción mecánica del drenaje del conducto torácico o sus tributarios linfáticos en la vena subclavia o por daño quirúrgico. Se reporta el caso de un paciente de dos meses de vida con diagnóstico de ventrículo izquierdo hipoplásico, en quien se encontró quilopericardio posterior a dos intervenciones quirúrgicas, y recibió tratamiento exitoso con drenaje pericárdico y sustitución de las grasas de la dieta por triglicéridos de cadena media.

Chylopericardium is a rare complication after congenital heart disease surgery. It is caused by mechanical obstruction of the thoracic duct drainage or its lymphatic tributaries to the subclavian vein or by direct surgical injury. We report the case of a two month-old boy with hypoplastic left ventricle diagnosis who developed chylopericardium secondary to two cardiac surgeries and who underwent a successful pericardial drainage procedure. Dietary fats were substituted by medium chain triglycerides.

Rabdomioma cardiaco como manifestación de esclerosis tuberosa. Presentación de dos casos y revisión de la literatura / Cardiac rhabdomyoma as manifestation of tuberous sclerosis. Presentation of two cases and literature review

Los rabdomiomas cardiacos son tumores benignos dependientes de las fibras musculares miocárdicas, los cuales usualmente son múltiples, pero tienden a disminuir tanto en número como en tamaño con el crecimiento, con una regresión espontánea en 90% de los casos. Hacen parte de los tumores cardiacos primarios, los cuales son poco frecuentes, con una incidencia que varía entre 0,0017% y 0,28%. El más frecuente de los tumores cardiacos primarios es el rabdomioma. Se describe asociación con esclerosis tuberosa hasta en 72% de los casos, razón por la cual ésta debe buscarse ante el hallazgo de rabdomioma cardiaco.

Cardiac rhabdomyomas are benign tumors derived from cardiac muscle fibers. They are usually multiple, but tend to decrease both in number and size with growth, with spontaneous regression in 90% of cases. These lesions are part of the primary cardiac tumors, which are uncommon, and have a variable incidence between 0.0017 and 0.28%. The most common primary cardiac tumor is the rhabdomyoma. An association between rhabdomyoma and tuberous sclerosis has been described in up to 72% of cases. For this reason, a patient with cardiac rhabdomyoma should be investigated for tuberous sclerosis.
