[ 1 ] - Assessment of Micro-vessel Density in Brain Glioma by CD105 Expression
Background& Objective: Micro-vascular proliferation is an important histological feature of brain glioma with more vascular proliferation is present in higher grades of glioma. CD 105 is expressed in new actively proliferating and immature endothelial cells in tumor environment and appears to be capable to distinguish between malignant neo-vasculature and normal vesse...
[ 2 ] - Expression of Prostate-Specific Membrane Antigen (PSMA) in Brain Glioma and its Correlation with Tumor Grade
Background & Objective Angiogenesis is an essential component of tumor growth. Expression of PSMA on the neo-vasculature of many solid tumors, including glioblastoma multi-form, has been determined. The pattern of expression suggests that PSMA may play a functional role in angiogenesis. Methods: expression of PSMA in dif...
[ 3 ] - Dyspnea as the First Manifestation of Silent Renal Cell Carcinoma
Renal cell carcinoma (RCC) accounts for only 3% of adult malignancies, and the lung is the most common site of metastasis of this tumor, which may be accompanied by pleural metastasis. However, solitary pleural involvement is very rare and its presentation with dyspnea as the first manifestation of RCC is extremely rare.We describe a 39-year-old male with episodes of dyspnea dating back 6...
[ 4 ] - Heterotopic Pancreas as a Leading Point of Intussusception: A Case Report
Heterotopic pancreas (HP) is generally asymptomatic and found incidentally. It can act very rarely as a leading point for intussusception. Thus, it should be considered as a differential diagnosis of the mass lesions leading to the intestinal intussusception. Herein, we report an unusual case of HP as a cause of ileocolic intussusception.
[ 5 ] - Mature Cystic Teratoma of Spinal Cord in A 16-Year-Old Male: A Case Report
Teratoma is a type of multipotential cell tumor, which includes a mixture of two or three germinal layers of ectodermis, endodermis, and mesodermis. Although neonatal sacrococcygeal teratoma has been frequently reported, its occurrence in older age is not common. In this study, we report a rare case of spinal intradural mature cystic teratoma in a 16-year-old male, emphasizing on considering th...
[ 6 ] - Knowledge of Laboratory Medicine in Medical Students: Is It Sufficient?
Background & Objective: Appropriate use of laboratory testing is essential for achieving safe and effective care to patient. Insufficient kno...
[ 7 ] - Necessity of Routine Repeat Testing of Critical Values in Various Working Shifts
Background & Objective: Accurate and timely reporting of critical values is an important issue. There is some doubt whether repeat testing of critical values would offer any advantage over single testing or not. The aim of this study was evaluation of utility of routine repeat testing of critical values in our referral center and to compare probable variations in different work...
