Diphyllobotrium Spp. como causa de diarrea crónica diagnosticada solo por colonoscopia o cápsula endoscópica

Se presentan dos pacientes con diarrea crónica, con múltiples estudios negativos, y que tenían en común la deficiencia de vitamina B12. Ambos pacientes tenían estudios repetitivos de parásitos en heces negativos. Sólo al realizarse colonoscopía en el primer caso y la cápsula endoscópica en el segundo, se pudo diagnosticar formas adultas de Diphyllobotrium spp. Luego del tratamiento antiparasitario, ambos pacientes remitieron completamente sus síntomas.

We present two patients with chronic diarrhea, with multiple negative studies, both had in common vitamin B12 deficiency. Both patients had multiple studies of parasites in negative stool. Only after colonoscopy in the first case and capsule endoscopy in the second case, it was possible to diagnose the adult forms of Diphyllobotrium spp. After treatment, both patients completely resolved their symptoms.

Incidence and epidemiology of adhesive capsulitis during the covid-19 pandemic / Incidência e epidemiologia de capsulite adesiva durante a pandemia de covid-19

ABSTRACT Objective: To evaluate a possible increase of adhesive capsulitis incidence during the COVID-19 pandemic. Methods: A total of 1,983 patients with shoulder disorders were retrospectively analyzed regarding gender, age, development of adhesive capsulitis and comorbidities (systemic arterial hypertension, diabetes mellitus, dyslipidemia, hypothyroidism, hyperthyroidism, depression, and anxiety) in two different periods: from March 2019 to February 2020 and from March 2020 to February 2021. Descriptive and quantitative variables were statistically analyzed. The program used for the calculations was SPSS 17.0 for Windows. Results: During the pandemic, there was a 2.41-fold increase (p < 0.001) in cases of adhesive capsulitis (compared to the previous year). Patients with depression and anxiety had a significantly increased risk by 8.8 (p < 0.001) and 14 (p < 0.001) times, respectively, of developing frozen shoulder (regarding the two periods studied). Conclusion: A significant increase in the incidence of frozen shoulder was observed after the onset of the COVID-19 pandemic in addition to a simultaneous increase of psychosomatic disorders. Prospective studies would help to ratify the idea contained in this research. Level of Evidence III, Observational Cross-Sectional Study.

São necessários estudos prospectivos futuros para ratificar a ideia contida nesta pesquisa. Nível de Evidência III, Estudo Transversal Observacional.

Inusual hallazgo en paciente cirrótico con anemia crónica e hipereosinofilia usando cápsula endoscópica: a propósito de un caso (video) / Unusual finding in cirrhotic patient with chronic anemia and hypereosinophilia using an endoscopic capsule: a case report (video)

We report a clinical case from a patient with alcoholic cirrhosis who had chronic anemia and carried out several endoscopic studies without evidence of active bleeding, a complementary study with endoscopic capsule was requested to search for a source of bleeding. In the analysis of laboratory data, the presence of hypereosinophilia stands out in parallel. The images obtained in the video capsule study show geoparasites helminth-type. After parasite treatment, anemia improves and the absolute eosinophil count is normalized.

Reportamos el caso de un paciente cirrótico por alcohol con anemia crónica quien se realizó varios estudios endoscópicos sin evidencia de sangrado activo, por tal motivo se solicitó estudio complementario con cápsula endoscópica para búsqueda de fuente de sangrado. En el análisis de los datos de laboratorio paralelamente destaca la presencia de hipereosinofilia. Las imágenes obtenidas en el estudio de la video cápsula muestran varios geoparásitos de tipo helmintos. Posterior al tratamiento antiparasitario mejora la anemia y se normaliza el recuento absoluto de eosinófilos.

Uso de injertos capsulares autólogos periprotésicos en mamoplastías estéticas / Used of peri prosthetics autologous capsular graft in aesthetic mammoplasty

INTRODUCCIÓN Y OBJETIVO: presentamos nuestra experiencia con el uso de injertos de capsulas autólogas peri protésicas en pacientes que evolucionaron con ptósis mamaria importante, que tenían implantes siliconados envejecidos implantados en plano subglandular y que además presentaban contractura capsular unilateral Baker III o IV y donde fue necesario cambiar de plano de implantación a sub muscular prolongando la cobertura protésica de musculo pectoral con capsulas autólogas a manera de injer-to simple para cubrir totalmente al implante siliconado, obtenidas de la mama sana contra lateral tipo I a II de Baker, seguido de la mamoplastia de elevación. El objetivo del trabajo es utilizar y reaprovechar tejidos autólogos sanos a cero costos. MATERIAL Y MÉTODO: registramos 12 pacientes operadas, de quienes se obtuvo un segmento de capsulas peri protési-cas autólogas resecadas en bloque de la mama sana contra lateral incluyendo el implante en su interior a través de disección digital simple o con electrobisturí, de prótesis implantadas en plano sub glandular. No se reglo el tamaño de la capsula en únicos moldes, sino se utilizó el tamaño requerido para la cobertura del implante, las cuales fueron injertadas uniendo el segmento medial y el distal del músculo pectoral, cubriendo y protegiendo el nuevo implante que fue implantado en plano submuscular. Posteriormente se ejecutó la mamoplastia de elevación. RESULTADOS: de las 12 pacientes, 1 evoluciono con shock anafiláctico por automedicación de una quinolona fluorada y presento edema generalizado, seroma moderado al 5to día de post operación lo que generó una revisión quirúrgica de urgencia, observando necrosis del injerto capsular motivo por el que fueron movidas. Y una paciente presento un aumento significativo y proyección del polo inferior mayor de la mama en relación con su homóloga seguramente porque se injerto un segmento mayor tamaño de capsula y no quedo a tensión suficiente en esa región, pero no se presentó ninguna reacción local inflamatoria excepto una forma asimétrica de esa mama. El resto es decir las otras 10 pacientes evolucionaron satisfactoriamente. CONCLUSIÓN: el uso de capsulas peri protésicas autólogas, son una alternativa técnica para tener en cuenta en mamoplastias de elevación cuando se opta por cambio de plano de implantación de las prótesis, cuando no se cuentan con matrices acelulares de alto costo, siendo un tejido con alta probabilidad de integración a cero costos y cuando es necesario cubrir al implante.

INTRODUCTION AND OBJECTIVE: we present our experience of using periprosthetic autologous capsule grafts in patients who evolved with significant breast ptosis, had aged silicone implants placed in the sub glandular plane, had unilateral capsular contracture Baker III or IV and had the need to change the plane of implantation to sub muscle plane to prolong the prosthetic coverage with autologous grafted capsules obtained from the healthy contralateral breast Baker type I to II, followed by lifting mammoplasty. The objective of this project is to use and take advantage of healthy autologous tissues at no cost. MATERIALS AND METHODS: we registered 12 operated patients from whom we resected, from the healthy contralateral breast, segments of autologous periprosthetic capsules, including the implant inside through simple digital dissection or with an electro scalpel of the prostheses located in the sub-glandular plane. The size of the capsule was not regulated in single mold, instead the required size to cover the implant was used and was grafted joining the medial and distal segment of the pectoral muscle, wrapping and protecting the new implant located at the submuscular plane. Subsequently, mammoplasty elevation was performed. RESULTS: of the 12 patients, 1 evolved, on the 5th day of surgery, with an anaphylactic shock due to self medication with a fluorinated quinolone tablet presenting a generalized edema, intense seroma, leading to an emergency surgical review and observing necrosis on the capsular graft, which had to be removed. Another patient presented a significant increase and projection of the lower pole of the breast in relation to its counterpart, surely because a larger segment of the capsule was grafted and was not tensioned enough in that region. No local inflammatory reaction was observed except for an asymmetric shape of that breast. The ten remaining patients evolved satisfactorily. CONCLUSIONS: the use of autologous periprosthetic capsules is an alternative technique to be considered for mammoplasty elevation when deciding to change the prostheses implantation plane, since it is a tissue with a high probability of integration at no cost, especially when high cost acellular matrices are not available and when it is necessary to cover the new implant.

Treatment of Irreparable Rotator Cuff Tears: Superior Capsular Reconstruction with Fascia Lata Allograft / Tratamento das rupturas irreparáveis do manguito rotador: Reconstrução capsular superior com aloenxerto de fáscia lata

Abstract Objective The objective of the present study was to evaluate the efficacy and safety of superior capsular reconstruction (SCR) using fascia lata allograft. Methods A prospective case series of 15 patients with irreparable supraspinatus tear who underwent SCR using fascia lata allograft. The American Shoulder and Elbow Surgeons (ASES) scale at 12 months after surgery was the primary outcome. The University of California Los Angeles (UCLA), Constant-Murley, and Single Assessment Numeric Evaluation (SANE) scales, in addition to the range of motion, were secondary outcomes. Radiological parameters were also evaluated by simple radiographs and magnetic resonance imaging (MRI). Results Fifteen patients completed 12 months of postoperative follow-up. The ASES score increased from 34.0 to 73.0 (p= 0.005). The UCLA, Constant-Murley, and SANE scales also showed statistically significant differences (p= 0.001; p= 0.005; and p= 0.046). In the evaluation of range of motion, there was improvement in elevation and in external rotation (95 to 140°, p= 0.003; 30 to 60°, p= 0.007). Six patients (40%) had complete graft healing. The clinical outcomes were significantly higher in the patients who presented graft healing. Conclusions Superior capsular reconstruction using a fascia lata allograft is a safe and effective procedure in short follow-up. Level of Evidence IV; Therapeutic Study; Case Series.

Resumo Objetivo O objetivo do presente estudo foi avaliar a eficácia e a segurança da reconstrução capsular superior (RCS) com a utilização do aloenxerto de fáscia lata. Métodos Uma série de casos prospectivos de 15 pacientes com ruptura irreparável do supraespinhal foi submetida a RCS com aloenxerto de fáscia lata, sendo adotada como desfecho primário a escala American Shoulder and Elbow Surgeons (ASES, na sigla em inglês) aos 12 meses do pós-operatório. Como desfechos secundários, foram adotadas as escalas da University of California Los Angeles (UCLA, na sigla em inglês), Constant-Murley, e Single Assessment Numeric Evaluation (SANE, na sigla em inglês), além da amplitude de movimento. Os parâmetros radiológicos também foram avaliados por radiografias simples e ressonância magnética (RM). Resultados Quinze pacientes completaram 12 meses de acompanhamento pós-operatório.

Na avaliação da amplitude de movimento, houve melhora na elevação e rotação externa (95 a 140°, p= 0,003; 30 a 60°, p= 0,007). Seis pacientes (40%) tiveram cicatrização completa do enxerto. Os desfechos clínicos foram significativamente maiores nos pacientes que apresentaram cicatrização do enxerto. Conclusões A RCS com aloenxerto de fáscia lata é um procedimento seguro e eficaz com um curto acompanhamento de tempo. Nível de evidência IV; Estudo Terapêutico; Série de casos.

Vasculitis intestinal y hallazgos en la videocápsula endoscópica: reporte de caso y revisión de la literatura / Intestinal Vasculitis and Endoscopic Video Capsule Findings: Case Report and Literature Review

Resumen Las vasculitis sistémicas pueden llegar a afectar los vasos sanguíneos de todos los tamaños, provocando necrosis e inflamación. La granulomatosis con poliangitis (GPA) es una vasculitis de vasos pequeños y medianos. Las presentaciones clínicas pueden ser locales o difusas en el tracto gastrointestinal. Presentamos el caso de un paciente con diagnóstico de vasculitis sistémica asociada a anticuerpos anticitoplasma (ANCA) mieloperoxidasa (MPO) (poliangitis microscópica) confirmada con biopsia renal, con clínica de 15 días consistente en astenia, adinamia, oliguria subjetiva, edema de miembros superiores e inferiores, hiporexia y melenas. En el examen físico, el tacto rectal fue positivo para melenas, posteriormente presentó anemización secundaria a melenas, por lo que se realizó videocápsula endoscópica en la que se evidenciaron hallazgos compatibles con vasculitis entérica. Durante su estancia presentó compromiso multisistémico dado por la afectación renal, pulmonar, neurológica y gastrointestinal, manejada en la unidad de cuidados intensivos (UCI), donde se iniciaron pulsos de esteroide sistémico y hemodiálisis. Conclusión: la vasculitis gastrointestinal es una complicación rara; sin embargo, ocurre y causa una grave amenaza para la vida de los pacientes. El diagnóstico diferencial debe cubrir otras enfermedades inflamatorias, especialmente la enfermedad de Crohn. Su adecuado reconocimiento influencia de forma significativa el pronóstico, pues el inicio rápido de la terapia con esteroides puede cambiar el curso de la enfermedad.

Abstract Systemic vasculitis can affect blood vessels of all sizes, causing necrosis and inflammation. Granulomatosis with polyangiitis (GPA) is a vasculitis of small and medium blood vessels. Clinical manifestations may be local or diffuse in the gastrointestinal tract. We present a patient's case with systemic vasculitis associated with anti-cytoplasmic antibodies (ANCA), myeloperoxidase (MPO) antibodies (microscopic polyangiitis) confirmed through renal biopsy, presenting a 15-day clinical picture consisting of asthenia, adynamia, subjective oliguria, edema of the upper and lower limbs, hyporexia, and melena. The digital rectal examination was positive for melena in the physical examination, later presenting melena with secondary anemization. An endoscopic video capsule was performed, showing findings compatible with enteric vasculitis. During his stay, he presented multisystemic involvement due to renal, pulmonary, neurological, and gastrointestinal involvement, managed in the intensive care unit (ICU), where systemic steroid pulses and hemodialysis started. Conclusion: although gastrointestinal vasculitis is a rare complication, it occurs and threats patients' lives. Differential diagnosis should cover other inflammatory diseases, especially Crohn's disease. Gastrointestinal vasculitis early diagnosis significantly influences prognosis, as prompt steroid therapy can change the course of the disease.

Experience in the Use of Video Capsule Endoscopy in Patients with Unexplained Iron Deficiency Anemia / Experiencia con el uso de la videocápsula endoscópica en pacientes con anemia ferropénica inexplicada

Abstract Introduction: The prevalence of iron deficiency anemia in developed countries has been estimated between 2-5 %, associated with high morbidity and mortality. Etiological identification is sometimes difficult and requires diagnostic methods, such as video capsule endoscopy (VCE). Aim: This study intends to characterize the findings of this technique in patients with unexplained iron deficiency anemia. Materials and methods: Descriptive observational retrospective study. We describe the VCE findings (PillCamSB2-SB3) in all patients seen between 2011 and 2019. The findings were interpreted according to the Saurin classification: normal (P0), uncertain potential (P1), and high bleeding potential (P2). Results: Of the 490 VCEs performed during the study period, 155 indicated iron deficiency anemia; 106 were women (68.4 %), and the mean age was 57.1 ± 16.6 years. The main comorbidities were cardiovascular in 23 (18.3 %) and arterial hypertension in 16 (12.6 %). Antiplatelets were present in 18 (15.4 %) and anticoagulants in six (5.1 %). Small bowel lesions were vascular in 44 studies (28.4 %), inflammatory in 33 (21.2 %), and neoplastic in seven (4.5 %). Angiectasias were the most frequent lesions in 33 cases (21.3 %). P2 lesions were present in 53 VCEs (34.2 %). Conclusions: VCE is helpful in the study of iron deficiency anemia and helps detect positive findings in the midgut in three out of four patients for which it is indicated. The most frequent significant P2 lesions were vascular. These findings allow providing adequate treatment.

Resumen Introducción: la prevalencia de la anemia ferropénica en países desarrollados se ha estimado entre 2 %-5 %, asociada con una alta morbimortalidad. La identificación etiológica a veces es difícil, y requiere de métodos diagnósticos, como la videocápsula endoscópica (VCE). Objetivo: el objeto del presente estudio fue caracterizar los hallazgos de esta técnica en pacientes con anemia ferropénica inexplicada. Materiales y métodos: estudio descriptivo, observacional y retrospectivo. Se describen los hallazgos de VCE (PillCamSB2-SB3) en todos los pacientes atendidos entre 2011 y 2019. Los hallazgos se interpretaron según la clasificación de Saurin: normal (P0), potencial incierto (P1) y alto potencial de sangrado (P2). Resultados: del total de 490 VCE realizadas durante el período del estudio, 155 se efectuaron con indicación de anemia ferropénica; 106 fueron mujeres (68,4 %) y la edad media fue de 57,1 ± 16,6 años. Las comorbilidades principales fueron cardiovasculares en 23 (18,3 %) e hipertensión arterial en 16 (12,6 %). La ingesta de antiplaquetarios se presentó en 18 (15,4 %) y anticoagulantes en 6 (5,1 %). Las lesiones en el intestino delgado fueron vasculares en 44 estudios (28,4 %), inflamatorias en 33 (21,2 %) y neoplásicas en 7 (4,5 %). Las angiectasias fueron las lesiones más frecuentes en 33 casos (21,3 %). En 53 VCE se presentaron lesiones P2 (34,2 %). Conclusiones: la VCE es útil en el estudio de la anemia ferropénica, y ayuda a detectar hallazgos positivos en el intestino medio en 3 de cada 4 pacientes en los cuales se indica su uso. Las lesiones P2 significativas más frecuentes fueron las vasculares. Estos hallazgos permiten enfocar un tratamiento adecuado.

Eminectomía bilateral como tratamiento para luxación crónica de articulación temporomandibular. Reporte de caso / Bilateral eminectomy as a treatment for chronic temporomandibular joint dislocation. Case report

Introducción: la luxación de la articulación temporomandibular es un desplazamiento del cóndilo fuera de sus posiciones funcionales dentro de la fosa articular y la eminencia articular, la cual ocasiona una pérdida completa de la función articular. La luxación crónica es toda luxación aguda que progresa sin un tratamiento específico y que puede ser de carácter recurrente. La eminectomía es un tratamiento quirúrgico definitivo contra la luxación crónica de articulación temporomandibular. Objetivo: reportar el caso clínico de un paciente masculino, de la tercera década de su vida, con diagnóstico de luxación crónica de la articulación temporomandibular de cinco meses de evolución y presentar una revisión actualizada de la literatura sobre este procedimiento quirúrgico. Caso clínico: el paciente fue tratado quirúrgicamente con eminectomía bilateral. Discusión: la eminectomía es un procedimiento quirúrgico controversial; sin embargo, recientes investigaciones lo catalogan como seguro y efectivo. Conclusión: el caso clínico presentado muestra un buen resultado.

Background: Temporo-mandibular joint dislocation is a displacement of the condyle, out of its functional positions within the articular fossa and articular eminence, causing a complete loss of joint function. Chronic dislocation is any acute dislocation that progresses without specific treatment and that can be recurrent. Eminectomy is a definitive surgical treatment for chronic temporomandibular joint dislocation. Objective: To report the clinical case of a male patient in the third decade of his life with a diagnosis of chronic dislocation of the temporomandibular joint of 5 months of evolution and to carry out an updated review of the literature on this surgical procedure. Case Report: The patient was treated surgically with bilateral eminectomy. Discussion: Eminectomy is a controversial surgical procedure; recent research classifies it as safe and effective.

Abordaje interhemisférico contralateral. Nota técnica / Contralateral interhemispheric approach. Technical note

El abordaje interhemisférico contralateral es una variante del abordaje interhemisférico transcalloso que permite optimizar el acceso a lesiones ubicadas en los ventrículos laterales o en sus paredes. La planificación del ángulo de entrada mediante neuronavegador nos permitió el manejo de un Cavernoma ubicado sobre el núcleo caudado e inmediato a la cápsula interna sin realizar callosotomía convencional ni comprometer las estructuras sensibles adyacentes.

Contralateral interhemispheric approach is a variant of the well-know interhemispheric transcallosal approach that allows to optimize the lateral wall ventricle lesions management. Neuronavigation planning allowed us to deal with a caudate nucleus cavernoma contiguous to internal capsule without conventional callosotomy and additional damage neither.

Morphologic and molecular study on the lens anterior capsule in systemic sclerosis / Relato sobre estudo morfológico e molecular da cápsula anterior do cristalino na esclerose sistêmica

ABSTRACT This study aimed to analyze the anterior lens capsule specimens from both eyes of a patient with systemic sclerosis and compare them to the eyes of a control patient. No significant differences between systemic sclerosis and control eyes were observed in the results from the hematoxylin-eosin and picrosirius staining. In the samples obtained from both systemic sclerosis and control eyes, there were expressions of caspase, a molecule expressed in cell death by apoptosis. Heparanase was overexpressed in the systemic sclerosis sample compared to the control sample. Therefore, the anterior lens capsule of the patient with systemic sclerosis is probably affected by the disease since it showed marked expression of heparanase 1.(AU)

RESUMO Analisamos as amostras das cápsulas anteriores do cristalino de uma paciente com esclerose sistêmica e comparamos com as de um paciente controle. Não foram observadas diferenças significativas entre esclerose sistêmica e controle nos resultados da coloração com hematoxilina-eosina e picrosirius. Nas amostras obtidas da esclerose sistêmica e do controle, obtivemos expressão de caspase, uma molécula expressa na morte celular por apoptose. A heparinase foi expressa de forma mais marcante na amostra de esclerose sistêmica quando comparada ao controle. Portanto, a cápsula anterior do cristalino da paciente com esclerose sistêmica provavelmente foi afetada pela doença, uma vez que mostrou expressão aumentada de heparinase 1.(AU)

Eficacia de la infiltración periarticular con anestésico local y adyuvantes para control del dolor postquirúrgico en la artroplastía total de rodilla / Effectiveness of peri-articular infiltration with local anesthetic and adjuvants for post-surgical pain control in total knee replacement

Resumen: Introducción: La artroplastía total de rodilla (ATR) es uno de los tratamientos ortopédicos más exitosos; sin embargo, se ha asociado a dolor postquirúrgico intenso en 30-60% de los pacientes. Nosotros planteamos que la infiltración de la cápsula articular de la rodilla durante la cirugía disminuirá el dolor postquirúrgico. Material y métodos: Estudio experimental, aleatorio, doble ciego, en pacientes sometidos a ATR unilateral entre Abril de 2018 a Enero de 2019. Los pacientes fueron divididos en dos grupos, el primero infiltración con placebo y el segundo con solución anestésica y adyuvantes (fentanilo, epinefrina y ketorolaco). Se cuantificó mediante escala visual análoga (EVA) del dolor a las cuatro, seis, ocho, 12, 18, 24, 36 y 48 horas postquirúrgicas, así como del consumo de analgésicos opioides y antieméticos. Resultados: Veinte pacientes en cada grupo, con un seguimiento de cuatro semanas. No hubo diferencias significativas en las características demográficas entre ambos grupos. Se observó un mejor control del dolor postquirúrgico en el grupo que recibió infiltración con anestésico y adyuvante, además de una disminución en el consumo de analgésicos opioides y antieméticos. No hubo diferencia en sangrado ni en la incidencia de infecciones entre ambos grupos. Conclusión: La infiltración pericapsular es un método seguro y eficaz, como parte de la analgesia multimodal en la artroplastía total de rodilla, ya que disminuye el dolor postquirúrgico, el consumo de opioides y antieméticos y no incrementa el sangrado postquirúrgico.

Abstract: Introduction: Total knee arthroplasty (TKA) is one of the most successful orthopedic treatments, however, it has been associated with severe postsurgical pain in 30-60% of patients. We propose that infiltration of the articular capsule of the knee during surgery will decrease postsurgical pain. Material and methods: Experimental, randomized, double-blind study in patients undergoing unilateral TKA between April 2018 and January 2019. Patients were divided into two groups, the first infiltration with placebo and the second with anesthetic solution and adjuvants (fentanyl, epinephrine and ketorolac). Pain was measured with the visual analog scale (VAS) at 4, 6, 8, 12, 18, 24, 36 and 48 hours postsurgical, as well as the consumption of opioid analgesics and antiemetics. Results: 20 patients in each group, with a follow-up of 4 weeks. There were no significant differences in demographic characteristics between the two groups. Better control of postsurgical pain was observed in the group that received infiltration with anesthetic and adjuvant, as well as a decrease in the consumption of opioid analgesics and antiemetics. There was no difference in bleeding or in the incidence of infections between the two groups. Conclusion: Peri-capsular infiltration is a safe and effective method, as part of multimodal analgesia in total knee arthroplasty, as it decreases postsurgical pain, opioid and antiemetic use and does not increase postsurgical bleeding.

Ileal neuroendocrine tumor: diagnosis by endoscopic capsule / Tumor neuroendocrino ileal: diagnóstico por cápsula endoscópica

The diagnosis of neuroendocrine tumors of the small intestine is usually challenging. They are infrequent, and the clinical course is insidious with nonspecific manifestations. Routine endoscopic and abdominal imaging studies are more often unremarkable. Therefore, distant metastases are frequently detected at the time of diagnosis. The tumor markers chromogranin A, synaptophysin, and neuron-specific enolase, and capsule endoscopy, and device-assisted enteroscopy are useful resources to establish a diagnosis. The aim was to present a case of neuroendocrine tumor of small intestine diagnosed with base in findings of the capsule endoscopy and further open surgery.

El diagnóstico de tumores neuroendocrinos del intestino delgado suele ser un desafío. Son infrecuentes y el curso clínico es insidioso con manifestaciones inespecíficas. Los estudios de imágenes endoscópicos y abdominales de rutina suelen ser anodinos. Por tanto, las metástasis a distancia se detectancon frecuencia en el momento del diagnóstico. Los marcadores tumorales cromogranina A, sinaptofi-sina y enolasa neuronal específica, y la cápsula endoscópica y la enteroscopía asistida por dispositivo son recursos útiles para establecer un diagnóstico. El objetivo de este trabajo fue presentar un caso de tumor neuroendocrino de intestino delgado diagnosticado con base en hallazgos de la cápsula endoscópica y de una nueva cirugía abierta.

Diagnóstico de divertículo de Meckel mediante cápsula endoscópica / Diagnose of Meckel's diverticulum through endoscopic capsule

Meckel's diverticulum can be present in up to 1.2% of the population. It is usually diagnosed as an imaging finding, but it can present with complications such as digestive bleeding, intestinal obstruction, diverticulitis, ulcers, and perforation, more frequently in childhood or infancy. The diagnosis workup for this condition will depend on their clinical manifestation, the most frequent being gastrointestinal bleeding of obscure origin or small intestinal bleeding. In this context, although capsule endoscopy is the preferred technique, its diagnostic yield for the detection of Meckel's diverticulum is not entirely clear and it has not been compared in a controlled studies with other diagnostic methods. Here we report the diagnosis of a Meckel diverticulum and its intestinal complications by means of capsule endoscopy in a patient with iron deficiency anemia and gastrointestinal bleeding

El divertículo de Meckel puede estar presente en el 1,2% de la población general. Usualmente es diagnosticado como un hallazgo, pero puede presentarse con mayor frecuencia en la niñez o infancia por sus complicaciones como hemorragia digestiva, obstrucción intestinal, diverticulitis, úlceras y perforación. El enfrentamiento diagnóstico de esta condición dependerá de la manifestación clínica, siendo lo más frecuente hemorragia digestiva de origen oscuro o de intestino delgado. En este contexto, si bien la cápsula endoscópica es la técnica de elección, su rendimiento diagnóstico para la detección del divertículo de Meckel no es del todo claro y no ha sido comparado de forma controlada con otras técnicas diagnósticas. En el presente caso se reporta el diagnóstico de un divertículo de Meckel y sus complicaciones intestinales mediante cápsula endoscópica en una paciente con anemia ferropriva y hemorragia digestiva.

Surgical Treatment of Post-traumatic Elbow Stiffness by Wide Posterior Approach / Tratamento cirúrgico da rigidez pós-traumática do cotovelo por via posterior ampla

Abstract Objective To demonstrate the clinical outcomes and complication rates of the surgical release with a single posterior approach in the treatment of post-traumatic elbow stiffness. Methods A prospective study with patients submitted to surgery between May 2013 and June 2018 in a single center. The access to the elbow was made through the posterior approach. The patients were followed up by an occupational therapy team, and were submitted to a standardized rehabilitation protocol, with static progressive orthoses and dynamic orthoses. The primary outcome was the range of flexion-extension of the elbow after 6 months. Results A total of 26 patients completed the minimum follow-up of 6-months. The mean range of flexion-extension of the elbow at the end of 6 months was of 98.3 ± 22.0°, with an amplitude gain of 40.0 ± 14.0° in relation to the pre-operative period (p< 0.001). The average flexion-extension gain at the end of 6 months was of 51.7% ± 17.1% (p< 0.001). The mean pronosupination at the end of 6 months was of 129.0 ± 42.7° (p< 0.001). Half of the cases had moderate and severe stiffness in the pre-operative period, compared with 7.7% at 6 months post-operatively (p< 0.001). The mean score for the Mayo Elbow Performance Score (MEPS) and Disabilities of the Arm, Shoulder and Hand (DASH) instruments was 74.4 ± 16.8 points and 31.7 ± 21.9 points respectively (p< 0.001 for both). The visual analogue scale (VAS) score presented no statistically significant difference compared to the pre-operative period (p= 0.096). Complications were observed in 6 (23%) patients, and no new surgical procedures were necessary. Conclusions The surgical release of the elbow associated with a rehabilitation protocol is a safe technique, with satisfactory results and low rate of complications.

Posible sangrado del intestino delgado. ¿Es la videocápsula endoscópica la mejor opción? / Is the videocapsule endoscopy the best option for diagnosis of possible bleeding from the small intestine?

Resumen En pacientes sin una causa clara de sangrado gastrointestinal luego de una endoscopia digestiva alta y baja, la causa se encontrará en el intestino delgado hasta en el 77 % de los casos. Ante el excelente rendimiento diagnóstico de la videocápsula endoscópica (VCE) para el estudio de este segmento del tracto gastrointestinal, surge la duda de si debería ser el método diagnóstico inicial de este grupo de pacientes con posible sangrado del intestino delgado (PSID) o si la realización de una nueva endoscopia alta y baja o algún método alternativo de estudio del intestino delgado debería serlo. En esta revisión se evalúa y evidencia el rendimiento diagnóstico superior y la mayor seguridad de la VCE como abordaje inicial de pacientes con PSID en relación con otros métodos. Sin embargo, se pone en tela de juicio la mejor costo-efectividad de este abordaje en nuestro medio, que en otros ha sido claramente demostrada.

Abstract When neither upper nor lower gastrointestinal endoscopy can find a clear cause of gastrointestinal bleeding, it will eventually be found in the small intestine in up to 77% of cases. Given the excellent diagnostic performance of video capsule endoscopy for studying this segment of the gastrointestinal tract, the question of whether it should become the initial diagnostic method for patients with possible bleeding from the small intestine arises. The alternatives are to perform additional upper and lower endoscopic procedures or to use some alternative method of studying the small intestine. This review documents and evaluates the superior diagnostic performance and greater safety of videocapsule endoscopy as the initial approach for possible bleeding from the small intestine and compares it with other methods. However, the cost-effectiveness of this approach, clearly demonstrated elsewhere, is questioned in our setting.

Fatores de virulência e susceptibilidade a antifúngicos de Cryptococcus Spp / Virulence factors and susceptibility to Cryptococcus Spp. antifungals

Criptococose é uma doença grave que afeta tanto imunocomprometidos quanto imunocompetentes, com isso analisar a virulência é fundamental para novas terapêuticas. Objetivo: Analisar a capacidade de virulência e susceptibilidade aos antifúngicos de Cryptococcus spp. isolados de líquor de pacientes de hospital do norte do Paraná. Métodos: A partir de dois isolados clínicos C. neoformans e C. gattii, realizou-se a confirmação da identificação. Para a virulência, avaliou-se o tamanho da cápsula, capacidade de sobrevivência após exposição a neutrófilos, produção de melanina e urease. No antifungigrama por difusão em disco utilizou-se: anfotericina B, cetoconazol, voriconazol, itraconazol e miconazol. Resultados: C. gattii destaca-se por maior desenvolvimento da cápsula além da melhor capacidade de sobreviver a fagocitose em relação ao C. neoformans. No antifungigrama, ambos os isolados se apresentam sensíveis às drogas estudadas. Conclusão: Esses achados contribuem para a compreensão das diferentes patogêneses entre C. gattii e C. neoformans.

Cryptococcosis is a serious disease that can affect both immunocompromised and immunocompetent individuals, thus the virulence analysis is fundamental for the development of new treatments. Objective: To analyze the virulence and susceptibility of Cryptococcus spp. isolated from cerebrospinal fluid of patients from a hospital in the north of Paraná. Methods: From two clinical isolates, C. neoformans and C. gattii were confirmed and identified. For virulence, capsule size, survival capacity after exposure to neutrophils, melanin production and urease were evaluated. In the disc-diffusion method, the following antifungals were used: amphotericin B, ketoconazole, voriconazole, itraconazole and miconazole Results: It was observed that C. gattii presents greater results for development of the capsule beside presenting the best ability to survive phagocytosis in relation to C. neoformans. In the disc-diffusion method, both isolates presented sensitivity to the studied drugs. Conclusion: These findings contribute to the understanding of the different pathogens between C. gattii and C. neoformans.

Reconstrucción de la cápsula superior en ruptura masiva e irreparable del manguito rotador / Superior capsule reconstruction in massive and irreparable rupture of the rotator cuff

Resumen: Introducción: La lesión masiva e irreparable del manguito rotador es un problema clínico que genera la pérdida de la función biomecánica del hombro. Esta lesión amerita una intervención oportuna, de modo tal que, previo a la artrosis, ayude a preservar la función articular durante el mayor tiempo posible. La opción de reparación de la cápsula superior con autoinjerto de fascia lata en la ruptura masiva e irreparable del manguito rotador es una técnica propuesta por Mihata, la cual ha demostrado obtener constantes mejorías de la función a corto y mediano plazo. Reporte de caso: Se trata de una mujer de 51 años con lesión irreparable del supraespinoso e infraespinoso y fallo en el tratamiento conservador. Clínicamente, se presentó con dolor de hombro intolerable y disfunción subjetiva; sin datos de artropatía moderada a severa, defectos óseos, rigidez o disfunción del deltoides, del dorsal ancho y del pectoral mayor. Se realizó reconstrucción de la cápsula superior con autoinjerto de fascia lata en Agosto de 2018 y seguimiento en las primeras 12 semanas. El resultado de este procedimiento mostró mejoría de las escalas SST de 58.33 y QD de 20.45 puntos con respecto a la valoración prequirúrgica (SST de 33.3 y QD de 27.7 puntos) y una movilización activa completa en abducción, flexión, extensión y rotación interna; el único arco de movilidad que no presentó mejoría fue la rotación externa del hombro, la cual se mantuvo en las mismas condiciones previas al procedimiento quirúrgico.

Abstract: Introduction: Massive and irreparable rotator cuff injury is a clinical problem that results in loss of shoulder function and merits timely intervention that helps preserve it as long as possible before arthropathy. The option of repair of the superior capsule with autograft of Fascia Lata in the massive and irreparable rupture of the rotator cuff, is a technique proposed by Mihata, which has demonstrated an improvement of function in the short and medium term. Case report: Female of 51 years old with irreparable tear of supraspinatus and infraspinatus, failure in conservative treatment, clinically with intolerable shoulder pain, subjective dysfunction without signs of moderate to severe arthropathy, no bone defects, stiffness or dysfunction of Deltoid, Latissimus Dorsi and Pectoralis Major. Superior capsule reconstruction was performed with autograft of fascia Lata in August 2018, with follow-up for the first 12 weeks. The result of this procedure showed improvement of the SST 58.33 and QD 20.45 scales compared to pre-surgical evaluation (SST 33.3 and QD 27.7). Full active mobilization in abduction, flexion, extension and internal rotation. The external rotation of the shoulder has no functional improvement.

Evaluation of quality of life and visual acuity after posterior capsulotomy with neodymium: YAG laser in adults / Avaliação da qualidade de vida e da acuidade visual após capsulotomia com Neodymium: YAG laser em adultos

Abstract Purpose: To determine the impact of neodymium:YAG (Nd:YAG) laser posterior capsulotomy on quality of life and visual acuity in adults. Methods: A prospective study that included patients over 65 years old with clinical indications for Nd: YAG laser capsulotomy. On the day of the procedure, corrected distance visual acuity tests, slit-lamp examination and posterior capsule opacification (PCO) photo documentation were performed, followed by application of the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). The PCO rate was evaluated with Evaluation of Posterior Capsule opacification (EPCO 2000) software. Four weeks after the posterior capsulotomy, corrected distance visual acuity was measured, and the NEI-VFQ-25 was applied again. Complications were also reported. Results : Sixty eyes from 45 patients were enrolled in the study. The mean age was 71.51 ± 6.38 years (65 to 93). Comparing the results before and after the Nd:YAG laser capsulotomy, there was a statistically significant improvement in quality of life according to the NEI-VFQ-25 (p<0.001) and in visual acuity (p=0.0). The mean score in NEI-VFQ-25 Questionnaire before capsulotomy was 62.07 ± 20.90 (16.81-95.90) and after was 83.95±19.49 (20.68 - 100.0). The mean CDVA before the procedure was 0.75 ± 0.35 LogMAR (0.1-1.3) and after was 0.21 ± 0.20 LogMAR (0.0-1.3). The mean PCO rate measured by the EPCO software was 0.688 ± 0.449. There was a positive correlation between the EPCO score and the total score of quality of life after Nd: YAG laser capsulotomy (r=0.845, p=0.00). Damage to intraocular lens was the only complication observed in six eyes (10%). Conclusion: Nd: YAG laser capsulotomy, in addition to improving visual acuity, is able to improve quality of life.

Resumo Objetivo: Determinar o impacto da capsulotomia posterior com laser de neodímio: YAG (Nd: YAG) na qualidade de vida e na acuidade visual em adultos. Métodos: Estudo prospectivo que incluiu pacientes acima de 65 anos com indicação clínica para capsulotomia com laser de Nd: YAG. No dia do procedimento, foram realizados testes de acuidade visual corrigida, exame com lâmpada de fenda e fotodocumentação da opacificação da cápsula posterior (OCP), seguido da aplicação do National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). A taxa de OCP foi avaliada utilizando o software de avaliação de opacificação de cápsula posterior (EPCO 2000). Quatro semanas após a capsulotomia posterior, a acuidade visual corrigida foi medida, e o NEI-VFQ-25 foi aplicado novamente. Complicações também foram relatadas. Resultados: Sessenta olhos de 45 pacientes foram incluídos no estudo. A idade média foi de 71,51±6,38 anos (65 to 93). Comparando os resultados antes e após a capsulotomia com laser Nd: YAG, houve melhora estatisticamente significante na qualidade de vida de acordo com o NEI-VFQ-25 (p <0,001) e na acuidade visual (p = 0,0). A média do escore total do questionário NEI-VFQ-25 pré capsulotomia foi de 62.07 ± 20.90 (16.81-95.90) e pós foi de 83.95 ±19.49 (20.68 - 100.0). A AVCC antes do procedimento foi 0.75 ± 0.35 LogMAR (0.1-1.3) e após foi 0.21 ± 0.20 LogMAR (0.0-1.3). A taxa média de OCP medida pelo software EPCO foi de 0,688 ± 0,449. Houve correlação positiva entre o escore EPCO e o escore total de qualidade de vida após a capsulotomia com laser de Nd: YAG (r = 0,845, p = 0,00). O dano à lente intraocular foi a única complicação observada em seis olhos (10%). Conclusão: A capsulotomia com laser Nd: YAG, além de melhorar a acuidade visual, é capaz de melhorar a qualidade de vida.
