This research aims to produce a diagnosis system for breast cancer by using Neural
Network depending on Back Propagation algorithm(BPNN) and Adaptive Neuro Fuzzy
Inference System ‘ANFIS’, the both of studies was done using structural features of
b
iopsies in “Wisconson Breast Cancer “data base.
In the end a comparison was made between the two studies of malignant- benign
classification of breast masses of breast cancer which has accuracy 95,95% with BPNN
and 91.9% with ANFIS system, this results can be consider very important if they
compared with researches depending on image features that obtained of various devises
like mammography, magnetic resonance.
This research aims to developing new method for breast tumors extraction and
features detection in breast magnetic resonance images by depending on clusteringand
image processing algorithms. At the beginning, one of clustering algorithms was used f
or
image segmentation and grouping pixels by their gray scale values. Then morphological
operations were implemented in order to remove noise and undesired regions, after that
suspected areas were extracted. Finally some shape features for extracted area were
detected, this features could be very useful for tumors diagnosis. A database consisted of
96breast magnetic resonance images were used and proposed approach was appliedby
MATLAB program, and we obtainedbreast tumors extraction and its features and
compared them with the doctor's opinion .
A retrospective study of 55 cases (mean age 55, range 82 ـ 35 years) of Gastrointestinal stromal tumors cancer admitted at AL Assad University Hospital , Lattakia , Syria. from 1\1\2002 to 1\1\2014 for studying its :locations ,risk factors and surgic
al management.
Stomach was the most common site for GISTs in 52.27% , small intestinal in 30.90%, rectum in 9.09% and colon in 7.27%.
The most common clinical signs and symptoms were: gastrointestinal bleeding 61.8% ,abdominal pain 21.81%.the histologic prognosis was high and moderate in 72.72% of patients.
Total gastrictomy was performed for one patient ,subtotal gastrictomy for 16 patients and a wedge in 11 cases. In 6 patients a segementectomy of small intestinal were performed. and in one patient a resection of the upper rectum performed.
Non Vascularized fibular Bone Grafts are consider one of the most method
which used in limp sparing surgery.
This study aims To knowledgement the early and later complications of the Non Vascularized fibular
grafts in bone reconstruction following
bone tumor resection.
the retrospective study was performed at 40 patients with malignant and benign
tumors, the study lasted from January 2007 to January 2011. during this period 40 surgical operation
were performed. This study depends on the arshef of bone Tumors unit- Albairouni hsspital.
A number of patients who had undergone to craniotomies for tumor resection,
re- intubated in ICU as urgent procedure. This may result in poor prognosis, overloading the staff, and
high cost.
The goal is looking for clinical, surgical, and laborato
ry risk factors helping in early detection of cases
which require keep ETT in place and maintaining of ventilation.
Objective: to assess the clinicopathologic features of tumors of the hair
follicles.
This study included 35 patients with tumors of the
hair follicles seen at dermatology and venereology hospital at Damascus
university during 2 years (2007-2008). A retrospective study of patient's files
and re-examination of their histological slides were done.
the aim of this study is to prove that laparoscopic approach in
experienced hands is the treatment
of choice for adrenal masses (up to 10 cm)
the study was conducted in Al Asad University
hospital between 2004-2006.By
reviewing the files of 22 p
atients with adrenal mass retrospectively and
prospectively all of them were done
laparoscopicaly except one case in which the operation was converted to
open approach .the variables that
considered in this study were the difficulty of the procsdure,time of surgery,
the ratio of conversion to the
classic approach (open adrenalectomy ^morbidity and mortality rates.
This article aims to assess the application of skull- base approaches and
their results in the management of different skull-base pathology in Al-
Muwasat university hospital in Damascus.
Different approaches to the skull base (Supraorbital, Crani
oOrbito-
Zygomatic, Extended middle fossa, Petrosal and Transcondylar) were used
according to the pathology and site of the lesion.
Primary cardiac tumors are considered rarely common tumors. They are
classified into two kinds of tumors: (1) Benign cardiac tumors frequently located
in the left cardiac chambers, mostly common is the Myxoma , which is treated
by complete good ex
cising surgery including excision of the tumor base. (2)
Malignant primary tumors, which prefer the right cardiac chambers, mostly
common are Angiosarcoma and Mesothelioma, whose primary treatment is
nearly complete excision surgery with the help of artificial heart and lung,
followed by chemotherapy and radiotherapy, which seldom prolong the life of
the patient for about three years.
