The aim of this study is to investigate the hemodynamic characteristics of brain death patients via PulseInduced Contour Cardiac Output (PiCCO). 20 brain-death patients were included in the test group, and 20 with GCS ≥ 8 were included in the control group. The hemodynamic characteristics Pre-load (ITBVI/ EVLWI), Cardiac Pump Function: (CI/SI/GEF/CFI/dPmax), Post-load: (SVRI) were collected by ...

The avowed object of this little book is to separate the study of cardic rhythms from " the intricate mass of information concerning instruments, curves, cardiac physiology, etc.," with which it is usually mixed up. It is divided into two parts: the first deals with the development of our knowledge of the heart rhythms, the important elements of the heart beat, the functional parts into which i...

multiple primary tumors in a single patient are relatively rare when four or more distinct lesions are considered. herein, we report a case of woman with four different primary tumors: meningioma, renal angiomyolipoma, spinal ependymoma and high-grade soft tissue sarcoma. there was no family history and hereditary syndrome. the genetic analysis was completely normal. to best of our knowledge, t...

Ovarian sex cord-stromal tumors are relatively infrequent neoplasms that account for approximately 8% of all primary ovarian neoplasm. Sex cord-stromal tumors of the ovary include granulosa cell tumors, fibrothecomas, Sertoli-Leydigcell tumors, steroid cell tumors, and sclerosing stromal tumors (SST). Sclerosing stromal tumors account for 2% to 6% of ovarian stromal tumors. Despite the rarity o...

abstract primary cardiac tumors are rare in all ages. their reported prevalence ranges from 0.001 to 0.03 percent in autopsy series. 25 percent of primary cardiac tumors are considered to be malignant, the majority of which are sarcomas. on account of the late presentation of symptoms in malignant heart masses, finding locally infiltrative tumors or systemically widespread cases at initial pres...

  Background: Tumors involving the hand skeleton are rare. However, a basic knowledge of hand tumors is necessary for every clinician. This is due to the importance of distinguishing typical benign tumors from life or limb threatening malignant ones. Methods: This study is a review of 99 cases of osseous hand tumors presented to the department of orthopedic surgery, Imam Khomeini Hospital in Te...

Introduction: Sarcomas account for 1% of all tumors originated in the head and neck regions in adults. They constitute a heterogeneous group of tumors of mesenchymal origin with multiple histological variants. The undifferentiated pleomorphic sarcoma (UPS) subtype is the most frequent variant with an incidence range of 2.7-38%.   Materials and Methods: This retrospective...

clavicular bone tumors occur in less than 0.5 percent of bone tumors. primary chondrosarcoma is very rare even among clavicle tumors. the main symptom is a touchable mass in 69 % of patients. dedicated centers using fna and cytology can reach a correct diagnosis in 94% of cases. treatment planning is done using simple x-ray, ct-scan, shoulder mri, chest ct-scan, and whole body technetium scan. ...

Metastatic tumors account for 1% of all oral malignancies. Metastasis to jaw bones is common, particularly in the mandible, rare in the oral soft tissues, and account for only 0.1% of oral malignancies. The majority of metastatic cases (70%) reported in the literature have primary tumors located in the lung, breast, kidney, and colon. Metastasis is a biological complex process that involves det...
