Petersen’s Hernia as a Complication of Bariatric Surgery: A Case Report

Background: Bowel obstruction due to Petersen hernia is a known but rare late complication of a R-Y surgery that can be a life threatening condition.  Delayed intervention may result in a high morbidity and even mortality. The clinical findings are not specific, In this context, imaging exams have an important part in the early detection and surgery of this condition. Cases Report: We describe the case of a 46-year old man presenting with acute abdominal pain and a history of gastric bypass five years previously. Abdominal Ultrasound did not reveal any significant findings. Indeed, through the use of multi slice computed tomography with IV and oral contrast , diagnosis of internal hernia was made and confirmed by laparotomy. Conclusion:Internal hernias are rare and difficult to diagnose, but they should be included in the differential diagnosis in intestinal obstruction cases and a history of abdominal surgery to reduce the high morbidity and mortality rates; surgical intervention shouldn’t be delayed

Nail fold Capillaroscopic Findings in Iranian Patients with Systemic Lupus Erythematosus

Background: Systemic Lupus Erythematosus is a progressive autoimmune disease with a wide range of morphological and functional changes in microscopic examination of small blood vessels. Identification of vascular diseases at early stage, plays an essential role in the prevention of its’ vascular complications. Nailfold capillaroscopy (NFC) is a non-invasive, easy, painless, and accurate method for evaluation of microcirculation and could be used for this purpose. The vast majority of studies on capillaroscopy in lupus patients have shown that changes are not specified to lupus –unlike Systemic Sclerosis- and are more likely to overlap with other diseases. Therefore, it was decided to check capillaroscopic changes and evaluate morphological changes and capillary structure in terms of quality and quantity in lupus patients.Materials and Methods: Nail fold capillaroscopic findings of 114 patients aged 19-75 years old were reviewed in this study. The results were categorized as: a) normal, b) non-specific morphological abnormalities, and c) Scleroderma-like pattern.  Results were analyzed qualitatively and quantitatively using SPSS 21 software. "Chi square" test was used to analyze the relationships between variables (P<0.05 was considered significant).Results: Our results show that Lupus –independent of any other microvascular risk factor can significantly affect the morphology and structure of blood circulation and these changes are shown with detail by nail fold capillaroscopy.Conclusion: Most of the findings are in line with similar studies performed by other investigators in this field. However, no specific pattern was recognized and microbleeding was higher in our patients with scleroderma-like pattern of involvement

Aplicación de varios métodos de procesamiento de imágenes por satélite en datos aster y landsat ETM + para identificar y separar las zonas de alteración en torno a la mina de oro de Akhtarchi, Khomein, Irán

The study area is located 100 km southeast of Arak and in two structural zones of Central Iran in the north and Sanandaj-Sirjan in the southern part. Regarding its geological structures, the area has become the source of important mines including the Akhtarchi gold mine, Aliabad iron mine, Ochestan feldspar mine, and Dali gold and copper mines. Therefore, promising areas for exploration activities are identified using the analysis of satellite images of ASTER and Landsat ETM + in the region to identify alteration areas. For this purpose, the necessary corrections were applied to the satellite images. Then, to identify the alteration parts related to the gold deposits, different satellite image processing methods of ETM + and ASTER were used.  These methods include making a false-color composite, band ratio, Selective Principal Components Analysis (SPCA), Spectral Angle Mapper (SAM) method, Spectral Information Divergence Classification (SID), Endmember Collection Dialog Components (ECDC), and innovative methods such as Principal Component Analysis (PCA) and Spectral Angle Mapper, as well as unsupervised classification methods. In the end, the major alterations in the region were observed. In the obtained images, the prophylitic zone and the phyllic and argillic zones in the region were observed. To introduce the optimal method, the results of the various methods mentioned were compared with each other and with the current situation of the mines. The alteration zones were identified through band ratio and SAM methods and the combined methods with more power. Finally, SAM, 2:1 ratio, and the combined methods were identified as successful methods for more accurate separation of the alteration zones.El área de estudio se encuentra a 100 km al sureste de Arak y en dos zonas estructurales del centro de Irán en el norte y Sanandaj-Sirjan en la parte sur. En cuanto a sus estructuras geológicas, la zona se ha convertido en la fuente de importantes minas, como la mina de oro Akhtarchi, la mina de hierro Aliabad, la mina de feldespato Ochestan y las minas de oro y cobre de Dali. Por lo tanto, las áreas prometedoras para las actividades de exploración se identifican mediante el análisis de imágenes satelitales de ASTER y Landsat ETM + en la región para identificar áreas de alteración. Para ello, se aplicaron las correcciones necesarias a las imágenes de satélite. Luego, para identificar las partes de alteración relacionadas con los depósitos de oro, se utilizaron diferentes métodos de procesamiento de imágenes satelitales de ETM + y ASTER. Estos métodos incluyen hacer una composición de color falso, relación de banda, análisis selectivo de componentes principales (SPCA), método de mapeador de ángulo espectral (SAM), clasificación de divergencia de información espectral (SID), componentes de diálogo de colección de miembros finales (ECDC) y métodos innovadores como Análisis de componentes principales (PCA) y mapeador de ángulos espectrales, así como métodos de clasificación no supervisados. Al final, se observaron las mayores alteraciones en la región. En las imágenes obtenidas se observó la zona profilítica y las zonas fílica y argílica de la región. Para introducir el método óptimo, se compararon los resultados de los diversos métodos mencionados entre sí y con la situación actual de las minas. Las zonas de alteración se identificaron mediante métodos de relación de bandas y SAM y los métodos combinados con más potencia. Finalmente, SAM, relación 2: 1, y los métodos combinados fueron identificados como métodos exitosos para una separación más precisa de las zonas de alteración

The reliability and validity of a designed setup for the assessment of static back extensor force and endurance in older women with and without hyperkyphosis.

ObjectiveThe purpose of this study was to investigate the intra-rater reliability and validity of a designed load cell setup for the measurement of back extensor muscle force and endurance.ParticipantsThe study sample included 19 older women with hyperkyphosis, mean age 67.0 ± 5.0 years, and 14 older women without hyperkyphosis, mean age 63.0 ± 6.0 years.MethodsMaximum back extensor force and endurance were measured in a sitting position with a designed load cell setup. Tests were performed by the same examiner on two separate days within a 72-hour interval. The intra-rater reliability of the measurements was analyzed using intraclass correlation coefficient (ICC), standard errors of measurement (SEM), and minimal detectable change (MDC). The validity of the setup was determined using Pearson correlation analysis and independent t-test.ResultsUsing our designed load cell, the values of ICC indicated very high reliability of force measurement (hyperkyphosis group: 0.96, normal group: 0.97) and high reliability of endurance measurement (hyperkyphosis group: 0.82, normal group: 0.89). For all tests, the values of SEM and MDC were low in both groups. A significant correlation between two documented forces (load cell force and target force) and significant differences in the muscle force and endurance among the two groups were found.ConclusionThe measurements of static back muscle force and endurance are reliable and valid with our designed setup in older women with and without hyperkyphosis
