Abstract
Background: The incidence rate of gastric cancer in Western countries has shown a remarkable decline in recent years although it is still the almost common cancer between men in Iran. The proto-oncogene MYC, located at 8q24.1, regulates almost 15% of human genes and is activated in 20% of all tumors. MYC amplification and overexpression of its protein product are observed in 15-30% of gastric neoplasia. The objective of this study was to find the preference of CISH or IHC in the diagnosis and prognosis of gastric cancer. Methods: In this cross-sectional investigation, 102 paraffin blocks samples of Iranian patients with gastric cancers were studied. All the patients had undergone primary surgical resection at the Cancer Institute Hospital, Tehran University of Medical Sciences from 1987 to 1993. CISH and IHC techniques were applied to the samples. CISH was carried out on 3-µm-thick tissue sections and with a ZytoDot CISH Implementation Kit (ZytoVision GmbH, Germany). IHC was down using the HRP method with the monoclonal antibody. A universal peroxidase-conjugated secondary antibody kit was used for the detection system. All samples were gastric adenocarcinoma and were selected randomly. Results: Our data revealed that both diffuse and intestinal types of gastric cancer occurred significantly in men more than women. Our results showed an indication of some correlation between grades and CISH results, although the difference was not significant. Our data also showed that CISH+ patients (43.1%) were more frequent in comparison with IHC+ patients (14.7%). There was a correlation between CISH and IHC. This result revealed that there was a significant difference between grades and IHC. There was also no statistically significant difference between CISH amplification in diffuse and intestinal types. Conclusion: Our conclusion is that for the treatment, management of stomach cancer, and monitoring of progress and prognosis of the tumor that is almost important for patients and clinicians, CISH test is a better and feasible to IHC test, with regards to sensitivity and specificity.

Abstract

                                                                
Background: The use of the traditional method for saphenous vein harvesting is associated with wound complications and not on-time patient mobilization. This has caused the improvement of minimally invasive vein harvesting techniques, together with general bridging. This study was designed to compare the therapeutic results of large saphenous vein harvesting with conventional and standard bridging techniques for lower extremity vascular reconstruction in patients with chronic lower extremity ischemia.
Methods: In this randomized clinical trial study, 66 patients with chronic lower extremity ischemia were randomly divided into two groups: large saphenous vein harvesting by conventional technique (continuous longitudinal incision) (n=30) and standard Bridging technique (small and multiple incisions) (n=36). Pain score (VAS), graft patency, wound complications, surgery results and patient satisfaction was recorded. The follow-up period was six months. (IRCT20190511043562N1).
Results: Graft patency (P=0.353), and Amputation-free Survival (P=0.397) did not show a significant difference between the two groups. Changes in pain score at rest (P=0.846) and movement (P=0.380) at different times did not show a significant difference between the two groups. One week after the operation, the incidence of infection in the bridging technique showed a significant decrease (P=0.045). During the six months of follow-up, the wound healing rate, ischemic pain relief, and claudication improvement were better in the bridging technique but did not show a significant difference with the conventional technique (P<0.05). Patient satisfaction was higher in the bridging technique but did not show a significant difference between the two groups (P<0.05).
Conclusion: It seems that the use of the bridging technique in venous resection large saphenous vein harvesting is associated with reducing wound complications and pain, reducing the length of hospital stay, increasing the speed of wound healing, and improving patient satisfaction. The duration of graft patency and Amputation-free Survival were similar in the two groups. We believe that each technique has advantages and disadvantages that should be considered by the patient and surgeon when choosing a surgical procedure.

Abstract
Background: Developmental disorders in children include a group of problems and limitations in learning and acquiring specific skills of each age group. The term global developmental delay is used to describe developmental disability in children under five years of age, which is in at least two areas of major development. Neuroradiological imaging such as brain MRI provides important information for physicians. The purpose of this study is to determine the role of brain MRI in predicting the clinical outcome of global developmental delay in children.
Methods: In this cross-sectional study, from 79 - from September 2013 to September 2018 at Motahari Clinic of Shiraz University of Medical Sciences, Shiraz Iran - eligible children with developmental disabilities, 37 patient who had brain MRI were selected as a sample and children scores in five ASQ clinical areas and MRI findings were reviewed and compared. Patients suffering from metabolic, genetic, trauma, infection and neoplasms problems and diseases were excluded from the study.
Results: Out of 37 patients studied, 23 were female and 14 were male with a dispersion of three 3 to 60 months of age. 31 of these children had at least one abnormal finding in brain MRI images and the other six were completely normal. In relation to the imaging findings, the highest frequency is related to abnormal head circumference with a prevalence of 54% and the lowest frequency is related to abnormal myelinization with a prevalence of 10.8%. Results of MRI findings correlation with developmental domains demonstrated that Children with white matter disorder on MRI show severe gross motor abnormality (P<0.049) and who had MRI finding of cortical problems suffer from developmental delay in fine motor area. (P<0.001).
Conclusion: Considering the mentioned findings; brain MRI can be a useful diagnostic tool in children with developmental delay and also focusing on the developmental area that is more likely to be affected, MRI can help with treatment and rehabilitation process of these children in the future.
