Renal Cell Carcinoma: Correlation of Multislice Computed Tomography Imaging (MSCT) Features and Pathologic Findings

Background and objectives: CT has an important role in detecting Renal cell carcinoma and differentiating it from other focal renal lesions, in addition to its importance in detecting secondary metastasis, staging the tumor, and investigating tumor recurrence after treatment. Renal cell carcinoma is the most common (85%) of all malignant renal tumors. Renal cell carcinoma is a common cause of death worldwide, so early and accurate diagnosis contributes to early and appropriate treatment. The purpose of the study correlates Multislice Computed Tomography Imaging findings with pathology results. Subjects and Methods: This was an analytic study, included 63 patients (76% male, 24% female) in Tishreen University Hospital, Lattakia, Syria. Patients underwent Multislice Computed Tomography MSCT scan and comparison with pathology results. Results: We found solid soft tissue mass (85%), cystic mass (15%), with heterogeneous enhancement. We detect calcification in 14%, local renal enlargement in 98%, deformity of renal countor in 95%, deformity of renal sinus and collecting system in 23%.. No fatty tissue density seen in all cases. In comparison with pathology MSCT has 10% false negative results in the diagnosis of renal vein involvement, 14% false positive resuls in the diagnosis of perinephric fat tissue involvement, and 4% false negative results in the diagnosis of Gerota's fascia involvement, and 1,5% false negative results in the diagnosis of adrenal involvement.

Evaluation of effectiveness of bilateral pedicle flap technique on the quality of gingival tissues recovery after upper lip frenectomy

The aim of this study was to evaluate the effectiveness of bilateral pedicle flap technique on gingival tissues recovery during three months of clinical follow-up.

A sedimentary conditions and reservoir characterization study of Juriba & transition zone formation in ELmhash structure using micro slides and geophysical well Logging

This research highlights on new manner in study of petroleum reservoir , by integrated between a sedimentary study, which comprises micro slides from side, and geophysical well logging interpretation from another side, in Juriba & Transition zone formation, in ELmhash structure oil field , at Euphrates depression – west DER Azzor -Syria. A selection (5) wells in ELmhash structure is Mahash (17-18-11-4- 7).

Medical Imaging Role in Renovascular Hypertension Diagnosis

Renal artery stenosis is an important clinical entity. its importance lies in that it may be a treatable cause of hypertension, and it is -when progress- a cause of chronic renal failure. The causes of renal artery stenosis are numerous, the most common are: atherosclerosis and fibromuscular dysplasia (accounts for more than 95% of cases). Digital Subtraction Angiography (DSA) is the standard reference in the radiologic diagnosis of renal artery stenosis, but it carries the risk of being invasive procedure. Doppler ultrasound is used in the evaluation of the renal arteries, and it has the advantage of being non-invasive and inexpensive.

The Study of Fluid retention parameters in porous thin films by AFM

We present in this paper a graphical study of regions of thermally deposited ZnS thin films on glass by atomic force microscope (AFM). This study consists of volume parameters and functional parameters of these films surfaces for the object of investigating the possibility to retain fluids by these films. For doing so, we registered Abbott-Firestone curves that are based on height distribution for these films, we measured volume and functional parameters in the whole pores. Using the thresholding operator we followed parameters distribution in depth of the surface. At the end we compared these parameters by the results of another study based on slice selection at different levels.

Nasal Reconstruction in Children with Modified Forehead Flap

Nasal reconstruction is considered as one of the difficult reconstructive problems to solve. That is due to the importance of the cosmetic appearance of the nose, the several types of tissues forming the nose and the complexity of the anatomy of the nose. Due to the small nostrils, delicate tissue and lack of surrounding tissues enough for reconstruction, this problem becomes more difficult to in the reconstruction of children’s noses, The aim of this research is to look at the cases of nasal reconstruction in children at Mouassat university hospital, and to suggest a new modification on the forehead flap, which leads to lengthening the flap by recruiting a piece of the Galea as a facial flap connected to the distal end of the forehead flap. This flap will be covered with a split thickness skin graft, then it will be folded to reconstruct the inner surface of the nose.
