ABSTRACT

Background: most of adults with Diffuse Low Grade Gliomas (DLGGs) are diagnosed with an average age of 39
years and the diagnosis is often made around fully functioning individuals. Currently extent of resection (EOR) is a
generally known variable that impacts overall survival (OS), progression free survival and malignant
transformation in these gliomas.
Aim of the study: this study aimed to evaluate the risks and benefits of maximizing the extent of resection of
DLGGS, while preserving neurological function.
Methodology and Materials: this was a prospective observational study of group of consecutive 20 patients with
initial imaging diagnosis of supratentorial DLGGs. Preoperatively planned for maximal resection even if
presuming the proximity of these lesions to eloquent cortex and their relative diffuse nature on imaging. Results:
40 % were near eloquent area and 30 % at eloquent areas. GTR achieved in 10% and STR in 65%. Pre-operative
Karnofsky Performance Scale (KPS) was 100 in 10%, 90 in 65%, 72 hours post-operative 70 in 60%. During the
first 6 months of follow-up KPS was 100 in 60% of the study cohort while only one patient (5%) died. After 6
months KPS was 100 and represented 95% of the whole study. LOS was the longest (4-16 days) in near eloquent
and shortest in eloquent (5-8 days). 30% had pre-operative uncontrolled seizures, which cured post-operative, 50%
stopped AED within a year. Average back to work period was 2.5 for eloquent, near eloquent 2.8 and non-eloquent
2.6 months.
Conclusion: careful pre-surgical planning based on proper reviewed history, recent imaging techniques and
utilizing up-to-date intra-operative technology is helping to maximize safe surgical resection, while saving patient
function and quality of life.

ABSTRACT
Background:
Upper extremity surgeries are recently performed under regional anesthesia. Regional
anesthesia of the upper extremity has several advantages over general anesthesia, such as improved
postoperative pain, decreased postoperative narcotic consumption, and reduced recovery time.
Supraclavicular approach of the brachial plexus block has gained importance for surgical and interventional
pain management purposes. Supraclavicular brachial plexus block provides an ideal condition for surgery of
the upper limb, maintains hemodynamic stability, decreases postoperative pain and allows for early
ambulation. However, the duration of the supraclavicular brachial plexus block is limited by the duration of
action of the local anesthetic used in the block.
Aim of the Work:
The aim of this study is to evaluate whether additional anesthetic effects could be
derived from addition of verapamil into local anesthetics injected into brachial plexus sheath.
Patients and Methods: This study was a prospective, randomized, controlled, double blind study had been
carried out in Matareya Teaching Hospital on 60 adult patients with a physical status ASA I & II
classification scheduled for upper limb surgeries for 6 months. Patients were randomly classified using
sealed envelopes into two equal groups (group I & group II) each of 30 patients.
Group I: 30 patients who
received 40 ml of 1% lignocaine (20ml) with 0.25% bupivacaine solution (20ml), Group II: 30 patients
who received 40 ml of 1% lignocaine(20ml) with 0.25% bupivacaine solution with 2.5mg verapamil
(20ml).
Results: Onset of sensory blockade time was marginally faster in Group II (12 ±1.8minutes) as compared
to Group I (12.6 ± 1.4 minutes). However this difference was statistically not significant. The increase in
duration of sensory blockade in Group II (209.90 ± 13.22 minutes) as compared to Group I (183.80 ± 11.68
minutes) was statistically significant (p < 0.001). Increase in duration of motor blockade in Group II
(172.00 ± 9.32minutes) as compared to Group I (168.20 ± 8.91 minutes) was statistically not significant (p
= 0.112).
Conclusion: we conclude that adding 2.5 mg verapamil with 0.25% bupivacaine solution (20ml) with 1%
lignocaine (20ml) to brachial plexus block can prolong sensory anesthesia without significant effect on
duration of motor block, onset of sensory and motor block.

ABSTRACT
Background:
Preterm premature rupture of membranes (PPROM) refers to PROM before 37 weeks of gestation.
It is responsible for, or associated with, approximately one-third of preterm births and the single most common
identifiable factor associated with preterm labor (PTL). This is the leading cause of perinatal morbidity and
mortality. Management of preterm labor includes bed rest, adequate hydration, prophylactic cervical cerclage
and use of tocolytic drugs. Administrations of tocolytic drugs including magnesium sulphate (MgSO4) and
ritodrine have considerable influences on pregnancy outcomes.
Objective: The present study aimed at comparing between the effects of magnesium sulphate administration and
ritodrine on delaying the active phase of labor in women with premature rupture of membrane (PROM) and
preterm labor, and determining the best drug with best results and fewest side effects.
Patients and Methods: The present study was conducted on 80 patients, with established PROM, whose
gestational ages ranged between 28 and 34 weeks, admitted to the hospital with PROM with PTL. In the current
study, patients were allocated into two equal groups: group A (MgSO4), and group B (Ritodrine).
Results: Both drugs (MgSO4 and ritodrine) were effective on prolonging the gestational age of the studied
women in both groups, and there was no significant difference between both groups. MgSO4 had fewer side
effects than ritodrine, and there was significant difference between both groups.
Conclusion: Both magnesium sulphate and ritodrine increase delay in reaching the active phase of labor in
women with PROM with preterm labor.

ABSTRACT
Background:
One of the goals of the antenatal clinic is to prevent and recognize adverse pregnancy outcomes
(APO). APO include hypertensive diseases of pregnancy, pre-term birth, pregnancy loss and maternal death.
Our objective is to investigate the knowledge and attitude of mothers on risk factors of developing APO in
Saudi Arabia.
Methods: A cross-sectional study of female school teachers was conducted. 195 women were selected from
four different schools in the region. Inclusion criteria were women of reproductive age who had at least one
previous pregnancy. A self-administrated questionnaire on the knowledge and attitudes of risk factors that
influence pregnancy outcomes were used.
Results:
192 out of 195 mothers completed the questionnaire (98.4% response rate). The mean age of those
women was 33.6. Responses revealed that most women have good knowledge about the risks resulting from
malnutrition, diabetes, and drug abuse as the agreement on all of these statements were 80%. However, their
knowledge about the importance of maternal education and their attitude towards cesarean section was not
satisfactory.
Conclusion:
Although our sample was an educated group; low knowledge was detected in essential items.
This study revealed that the public had extremely low knowledge regarding cesarean section, the importance of
maternal age during pregnancy and how mother education can affect the delivery of her newborn. We
recommend that pregnant women should be educated in the importance of attending the antenatal clinic
regularly.

ABSTRACT
Background:
Nasopharyngeal carcinoma is an endemic disease of Southeast Asia with incidence rates of
between 15 and 50 per 100 000. There is an intermediate incidence in North Africa and Far Northern
hemisphere while in the West the disease occurs sporadically. In Egypt the incidence rate is low and the peak at
age (50-54) is 3.4%, and other age varying between 0.3 and 0.4 per 100 000.
Aim of the Work:
The aim of this study was to evaluate and compare both techniques as regard their efficacy
on tumor response, local control, overall survival and progression free and treatment related toxicity between
both techniques.
Patients and Methods: This retrospective analysis included 54 patients diagnosed with primary
nasopharyngeal carcinoma recruited from the clinical oncology department, Ain Shams University and the
International Medical Center during 3 years (January 2014 -December 2016). They were divided into 2 groups,
group A was treated using 3D conformal radiotherapy (CRT) whereas group B was treated using intensity
modulated radiation therapy (IMRT).
Results: In general, acute toxicity was tolerable and complete healing was the rule. As a whole, group A
showed a higher toxicity profile as compared to group B. IMRT was able to decrease xerostomia and spare at
least part of the parotid gland excretory function which was shown in the salivary gland scintigraphy. Results
of the dosimetric comparison between both techniques showed that IMRT had a better tumor coverage and
conformity index. Homogeneity index was similar in the two groups. Also, doses received by the risk
structures, particularly parotids, was significantly less in the IMRT plans than those of 3D-CRT. Conclusion:
IMRT is considered as a more advantageous radiation treatment technique as it can deliver high-dose
irradiation to defined tumor targets while minimizing the dose delivered to the surrounding normal organs and
tissues, thereby improving the therapeutic ratio of radiation therapy. IMRT has been shown to offer superior
dose conformity to the tumor target and better sparing of critical organs in the treatment of NPC.

Placenta previa is defined as ,the growth of placenta in the lower uterine segment over or near
the internal cervical osseous, it's an obstetric complication which usually occurs in the second trimester. A
lot of literatures have been done to study the risk factors associated with its development. Therefore, assessment
of the recent literatures must be done to provide a summarized paper analyzing the various risk factors that stands
behind placenta previa development, which will help in prevention and control the increasing in the incidence of
the condition. Objective: This study aimed to assess the various studies that investigate the risk factors that stand
behind the development of placenta previa, and provide a reference paper analyzing the last progression has been

ABSTRACT
Background:
Compared to other refractive surgeries, implantation of phakic intraocular lenses (pIOLs) have more desirable
results and are potentially reversible procedures due to the possibility of explanting these lenses. These methods usually do not
require expensive or special surgical equipment and most ophthalmologists are able to perform these procedures; however
disabilities resulting from pIOLs are more severe compared to corneal refractive surgery. Due to the potential risk of damage
to anterior segment structures, especially corneal endothelial cell loss.
Aim of the Work: to compare between anterior chamber (AC) pIOL and posterior chamber (PC) pIOL in patients with
myopia as regard:
1- Uncorrected and best corrected visual acuity (UCVA & BCVA).
2- IOP(Intra ocular pressure).
3- Endothelial cell count (ECC).
4- Postoperative inflammation and complications.
Patients and Methods: This prospective comparative study included 30 eyes of patients suffering from high myopia at Al-Hussein
University Hospital from 2017 to 2018. The patients were divided into two groups:
Group (A): included (15) eyes where Polymethyl methacrylate (PMMA) iris-fixated AC pIOL were implanted (Artisan). Group (B):
included (15) eyes where the PC pIOL were implanted (Implantable CollamerLens (ICL V4).
In this study we did pre and postoperative specular microscopy, pentacam and IOP measurement by applanation tonometer to
evaluate endothelial cell count and IOP changes over 6 months. The main outcome measures were central corneal ECC, the
percentage of corneal endothelial cell loss and IOP changes. Secondary outcome measures were UCVA, BCVA, manifest refraction,
and complications.
Results: The mean pre-operative ECC in Group A was 3365±403 cell/mm² ranged from 2830 to 3846 cell/mm². In Group B, it
was 3329±356 cell/mm² ranged from 2901 to 3989. Post operative mean ECC in group A was 3183±344 cell/mm² ranged
from 2609 to 3686. In Group B, it was 3251±361cell/mm² ranged from 2432 to 3621 at 6 month after surgery.
The mean percentage endothelial cell loss in group A was 5.4% While in group B, it was 2.3% at the end of the follow up
period (6 months). The mean pre-operative IOP in group A was 15.63 ±1.74 mmHg ranged from 12 to 18.2 mmHg, while in
Group B, it was 15.53 ±1.98 mmHg ranged from 13 to 20 mmHg. Post operative mean IOP in group A was 14.95±1.01 mmHg
ranged from 12.5 to 16.2 mmHg, while in Group B, it was 14.69±1.20 mmHg ranged from 12.6 to 16.7 mmHg at 6 month
after surgery. The mean pre-operative UCVA in Group A was 0.03 ± 0.011 ranged from 0.01 to 0.04, while in Group B, it was
0.06 ± 0.023 ranged from 0.01 to 0.083. And by the end of the 6th month after surgery, the mean UCVA was 0.39 ± 0.10 in
Group A, while it was 0.5 ± 0.27 in Group B. The mean pre-operative BCVA in Group A was 0.3 ±0.12 ranged from 0.16 to
0.7, while in Group B, it was0.4 ± 0.22 ranged from 0.25 to 1.00 the mean BCVA at 6 month after surgery was 0.49± 0.12 in
Group A, while it was 0.62 ± 0.23 in Group B. The mean pre-operative spherical error (SE) in Group A was -15.3 ± 2.68 D
ranged from -11D to -20D, while in Group B, it was -13.72 ± 3.97D ranged from -7D to -20.25D. by the end of the 6th month
after surgery, the mean post operative SE was-1.02 ± 0.53 in Group A, while it was -1.18 ± 0.67 in Group B.
Conclusion: Our study revealed that pIOLs implantation (AC IOLs or PC IOLs) in high myopes had excellent results
including; stability of refraction for high myopes, reversibility, high optical quality, potential gain in visual acuity,
preservation of corneal architecture, asphericity and accommodation the comparison between the two types of pIOLs proved
that the ICL was superior over the Artisan as regards the effect on corneal endothelium and postoperative AC inflammation,
and they were equal as regards predictability, efficacy and the effect on IOP.

ABSTRACT
Background: Free-living amoebae (FLAs) in drinking water exerts an indirect public health hazards as they may
harbor pathogenic microorganisms that can escape drinking water treatment processes and reach to end user. The aim
of this study was to observe the existence of free-living amoebae through drinking water treatment plants in Great
Cairo governorate, Egypt. Water samples were collected from 3 drinking water treatment plants (DWTPs) and
filtered through nitrocellulose membranes, then placed on non-nutrient agar with Escherichia coli for cultivation of
free-living amoebae. Results:The obtained amoebae were morphologically identified and confirmed to genus level.
The results revealed that the occurrence of free-living amoebae in intakes and finished water of the examined
DWTPs reached 95% and 31%, respectively. The removal percentage of free-living amoebae through different
treatment processes reached its highest rate in Rod Elfarag DWTP (100%), followed by Embaba DWTP (63.64%),
and reached to (41.67%)in Shubra El-Kheima DWTPs. Almost all the morphologically identified (FLA) strains
proved to be related to genus Acanthamoeba, Naegleria. Conclusion: the presence of free-living amoebae in
drinking water exerts an indirect public health hazards as they may harbor pathogenic microorganisms that can
escape drinking water treatment processes and reach to end user.

ABSTRACT
Background:
Surgical excision using the Harmonic Scalpel is a modern technique for symptomatic third-
and fourth-degree hemorrhoids. The resulting mucosal defect is then left open.
Objectives: The purpose of this study was to compare techniques of hemorrhoid excision using the
Harmonic Scalpel versus the routine Milligan-Morgan technique.
Methods: From August 2017 to May 2018, 30 patients underwent surgical excision of complex grade III or
grade IV hemorrhoids via the Harmonic Scalpel another 30 patients operated with the traditional Miligian
Morgan technique. Data collected about patient clinical condition and perioperative details including
operative time and blood loss then post-operative acute pain and delayed pain and other complications then
the quality of life after returning to routine life including degree of satisfaction of the patients were recorded
in a master sheet and short form survey for documentation and statistical analysis.
Results: Both groups were comparable in terms of patient demographics and type of anesthesia. There were
no late complications. Mean follow-up was 4.9 (range, 4­6) months. Conclusion: hemorrhoidectomy with
Harmonic Scalpel significantly reduces perioperative time, blood loss and thus postoperative pain, without
diminishing quality of life.

ABSTRACT
Objectives: To assess the relation between use of Intraoperative nerve monitoring (IONM) in thyroid surgery and
the prevalence of RLN injury, and to assess its significance of IONM in reduction of RLN injury among patients
who underwent thyroid surgery.
Background: Recurrent laryngeal nerve (RLN) palsy is one of the big concerns for surgeons during thyroid
surgery. Surgeons tried to find ways to identify this nerve and preserve it. The most popularly used way is the use
of Intraoperative nerve monitoring (IONM).
Methods:
In this retrospective study, we collected the data for all cases that underwent thyroid surgery in Security
Forces Hospital (SFH), Riyadh, Saudi Arabia during the period of 2010 to 2012. We divided participants to two
groups, those who used IONM and those who did not used IONM. The statistical Package for Social Sciences
(SPSS, version 22) was utilized for data entry and analysis. Categorical variables were described by frequencies
and percentages. Descriptive analysis involving Chi-square test was used to test significance of association
between categorical variables. The level of significance was set at P< 0.05.
Results:
Post-operation RLN injury was higher in those who underwent thyroid surgery without IONM, but the
difference was insignificant (p=0.460). Three of those patients who underwent the surgery without IONM has RLN
injury (3.1%), and no RLN injury reported of those who underwent surgery with IONM (0%).
Conclusion:
IONM could help in identifying the RLN and preserving it from injury. Although, in this study there
were insignificant correlations between RLN injury and IONM. Further researches on a larger-scales is
recommended to get more informative results and allow better comparison.

ABSTRACT
Background:
Brachial plexus blocks are among the most commonly performed peripheral nerve blocks for upper
extremity surgeries in clinical practice. Local anesthetics alone for supraclavicular brachial plexus block provide
good operative conditions but have shorter duration of postoperative analgesia. Several adjuvants added to local
anaesthetics in brachial plexus block are used to achieve quick, dense, and prolonged block. Dexamethasone has
been shown to prolong peripheral nerve blockade in animals and, when added to bupivacaine, to extend the
duration of analgesia in humans.
Objective: The aim of the current study was to evaluate the effects of adding dexamethasone (8 mg) to 28 ml of
bupivacaine 0.5% in ultrasound-guided supraclavicular brachial plexus block for upper limb orthopaedic surgery
versus bupivacaine 0.5% alone.
Patients and Methods
: The study included patients scheduled for elective upper limb orthopaedic surgery. A
randomized double-blinded controlled study is the design used in this study. It was carried on 40 patients who
were divided into two groups; 20 patients of each: group B (control group): patients received 28 ml of
bupivacaine 0.5% + 2 ml of normal saline and group D (study group): patients received 28 ml of bupivacaine
0.5% + 8 mg of dexamethasone (2 ml).
Results: There was significant difference between both groups as regards the onset of sensory and motor block,
group D has faster onset sensory block (10.30 ± 2.27 versus 12.85 ± 2.5 minutes, as well as motor block (15.15 ±
2.37 versus 18.25 ± 2.22 minutes). The duration of sensory block was significantly prolonged in group D than in
group B (18.45 ± 2.26 versus 10.33 ± 1.54 hours) as well as the duration of motor block (14.18 ± 2.24 versus 8.34
± 1.50 hours). There was significant prolongation of the duration of postoperative analgesia and less doses of
postoperative rescue analgesic in group D.
Conclusion: We concluded that addition of 8 mg of dexamethasone to bupivacaine 0.5% in ultrasound guided
supraclavicular brachial plexus block shortened the onset times of both sensory and motor blocks, significantly
prolonged their durations, and prolonged the analgesia of brachial plexus block with subsequent consumption of
less amount of postoperative analgesics in comparison to bupivacaine 0.5% alone.

ABSTRACT
Background:
Liver transplantation is currently accepted as a first line treatment for patients with end-stage acute or
chronic liver diseases. Graft survival and overall patient survival have steadily improved since the first transplants
were performed in the early 1960s, but a significant percentage of transplants develop complications related to
vascular and biliary insufficiency. Graft ischemia after liver transplantation is associated with a high incidence of
morbidity and mortality. Aim of the Work: was to evaluate the sensitivity of Duplex ultrasound in detection most of
vascular complication after liver transplantation in correlation with CT angiography. Patients and Methods: The
study was done from July 2017 until January 2018, where 20 cases who underwent living donor liver transplantation
with post-operative complications. The cases were done at Dar Al Fouad Hospital and National Liver Institutes. The
cases were 16 males and 4 females. All cases where admitted to post-transplanting intensive care unit in the
postoperative period where a routine full laboratory and radiological assessment were done. The laboratory
assessment included full liver function tests, kidney function tests, complete blood picture, and C-Reactive
Protein. Immunosuppressant level and bilirubin level in drains had also done. Results: The patient age ranges
from 43 to 80 years with the mean age of 61.5 years. Eighteen cases had hepatitis C related cirrhosis (90%) One case
had veno-occlusive disease related cirrhosis (Budd Chiari syndrome). One case was Wilson disease. About 95% of
cases were suffering from end stage liver disease. The results we have reached are that Doppler U/S sensitivity in
diagnosis of these complications is about 75%. Conclusion: It could be concluded that gray-scale US and color
Doppler are the investigations of choice in postoperative liver transplantation. They can be used as routine steps in
the assessment of liver transplant graft postoperatively in recipient patient as early as possible within the first 3 days
after operation and used as a late follow up, as they are noninvasive, safe, cheap, and accurate. Routine use of gray-
scale US and color Doppler showed to minimize the impact of postoperative complications and maximize both graft
and recipient patient survival.

ABSTRACT
Aim of the work: this study demonstrated the drastic effects of ionizing radiation on the heart tissue of the
adult male albino rats and the possible radio protective role of AFA extract.
Material and Methods: a total of forty-eight mature male albino rats (Rattus rattus) weighing 180-200g were
fed on standard rodent pellets. Rats were equally categorized into four groups; each group contained 12 rats.
These groups were: 1-untreated normal control rats (C); 2- rats exposed to 4Gy of gamma-radiation (Irradiated
group R) and then they were sacrificed on days 5 and 21 (R1& R2 groups respectively) post-irradiation; 3- rats
were treated orally with 94.5mg/kg body weight/day of AFA extract for 3 weeks (AFA group) and then they
were sacrificed on 5 and 21 days (A1& A2 groups respectively) post- treatment; 4- rats were treated orally with
94.5mg/kg body weight/day of AFA extract for a period of one week before irradiation and three weeks after
irradiation (AFA-irradiated group), then the rats were sacrificed on 5 and 21 days (AR1& AR2 groups
respectively) post-irradiation and treatment, then the hearts were immediately excised.
Results: many drastic changes were observed in the cardiac muscle fibres of rats of R1 group. These changes
included: numerous hemorrhagic areas which contained hemolyzed blood cells and some nuclei of
myocardiocytes were pyknotic and others were hypertrophied with destruction in some fibres and widened
endomysium. Aggravated changes were also observed in the heart of rats of R2 group such as highly elongated
and congested cardiac blood vessels which contained hemolyzed blood cells and hemosiderin granules,
numerous hemorrhagic areas, necrotic areas and widened endomysium. On the other hand, highly increased
collagen fibres and amyloid- deposits were also noticed in the cardiac tissues of rats of R1 and R2 groups with
decreased PAS positive materials, total protein and DNA materials. Normal architecture of the cardiac muscle
fibres was detected in the rats of A1, A2 groups with slightly increased collagen fibres and slightly decreased
PAS positive materials, total protein, amyloid- protein and DNA materials. Also, AR1, AR2 groups showed
somewhat normal appearance and well developed cardiac muscle fibres, but some dilated endmysium spaces
were still detected in the cardiac muscle fibres of rats of group AR2. Furthermore, increased collagen fibres and
amyloid- deposits were realized in the cardiac muscle fibres of rats of AR1, AR2 groups with decreased PAS
positive materials, total protein and DNA materials.
Conclusions: AFA showed cardio- protective effect and powerful antioxidant action. So, it can be used under
medical supervision as a natural supplement.

ABSTRACT
Background:
Infection prevention and control is required to prevent the transmission of communicable
diseases in all health care settings. The risk of acquiring a healthcare associated infection is related to the mode
of transmission of the infectious agent. As a result we wanted to assess the awareness level of infection control
among medical students. Objective: In this research we aim to identify the extent of knowledge, awareness, and
attitude regarding infection prevention and control among medical students in Taif University. Methods: The
researchers used the descriptive method for its relevance to the current research. The research population
included 250 medical students in Al Taif University. The researcher designed questionnaire as a data collection
method to serve the purpose of this research, and the descriptive approach was used for its relevance to the
current research. Conclusion: Most students were almost completely aware of the risk of infection transmission
through the hospital, and about all the precautions needed to prevent and control the infection within the
hospital. Also, the students were aware about the different kind of infectious disease.

ABSTRACT
Background:
Keratoconus is the most common corneal ectasia. It usually appears in the second decade of the
life and affects both genders and all ethnicities. Tomographic-based data have added significantly more
information to the screening of corneal ectasia. In addition to anterior corneal analysis, tomography also
provides information about the posterior cornea and the pachymetric distribution, which can increase our ability
to identify early and subtle corneal changes.
Aim of the Work:
The main aim is to determine how the corneal volume measurement changes in different
diameters of corneal tissue, in the central 3 mm and 5 mm in mild and severe cases of keratoconus; in an
attempt to quantify the loss of corneal tissue in keratoconus.
Patients and methods: This cross-sectional study included 20 eyes of keratoconic patients, from 15 to 36 years
old. They were divided into 2 groups, each group included 10 eyes: Group A: mild keratoconic cases with
steepest keratometry reading lower than 45 D. Group B: severe cases with steepest keratometry greater than 52
D, All cases were diagnosed as keratoconus using pentacam parameters.
Results: Corneal volume at 3 and 5 mm diameter was significantly lower in the severe keratoconic cases than
in mild cases (P<0.01).
Conclusion: based on the data in our study, we think the effect of keratoconus is not limited to corneal
thickness. Rather, it affects all anterior segment parameters of the eye and results in significant alternations with
the progression of the disease. There is a clear reduction of corneal volume in early keratoconus, and such
reduction increases significantly with the severity of the disease. Measurement of corneal volume could prove
to be a useful tool to monitor the progression of the disease and in other applications, such as assessing the
effect of treatments including corneal collagen crosslinking and implatation of Intacs.
Recommendations: Further studies on a larger scale of patients are needed to confirm the results obtained by
this work.

ABSTRACT
Background:
Functional magnetic resonance imaging (MRI) improves tissue characterization and staging of bone
tumors compared to the information usually supplied by structural imaging. Dynamic MRI and diffusion MRI can be
performed in everyday practice. Tumour characterization can benefit from perfusion MRI with dynamic gadolinium
injection and enhancement time-intensity curve analysis combined with quantitative and qualitative diffusion MRI.
Aim of the Work:
is to elucidate the role of advanced MRI techniques in diagnosis of pediatric bone tumors and to
assess the diagnostic potential of Dynamic contrast enhancement (DCE) in conjunction with Diffusion weighted
imaging (DWI) in differentiating benign from malignant bone tumors.
Patients and Methods:
a prospective study conducted on thirty pediatric patients with clinically suspected and
radiologically proven bone tumor or tumor like lesion. The patients were referred from the Department of
Orthopedics, Ain Shams University. The patients were investigated using 1.5 Tesla magnetic resonance device. They
were subjected to conventional MRI and DCMI.
Results:
DWI with measurement of Apparent diffusion coefficient (ADC) values helped in the differentiation of
benign and malignant bone tumors, and that the best cut-off criterion is ADC of 0.9 and this means that 0.9
indicates malignant result while >0.9 is defined as benign results with overall sensitivity 100% and specificity 100%.
A type II curve was seen in 23 cases (one malignant and twenty two benign), type IV was seen in 5 cases (all are
malignant) and type V curve was seen in two malignant cases (after chemotherapeutic treatment). ROC analysis for
the Dynamic contrast enhancement (DCE) showed a sensitivity of 75 % and specificity of 100%.
Conclusion:
DWI and DCE-MRI had been proven to be highly useful in the differentiation of benign and malignant
bone tumors. Measurement of ADC values improved the accuracy of the diagnosis of bone tumors. Moreover; they
could be used in the follow up of tumors and their response to therapy.

ABSTRACT
Background:
Hepatitis C virus (HCV) infection is considered a national progressing problem that threatens the
life of Egyptian people as Egypt has the highest prevalence of HCV infection in the world with prevalence rates
of 14.7 % of the adult population. HCV infection causes chronic hepatic inflammation and severe liver diseases,
such as liver cirrhosis and hepatocellular carcinoma. Currently, HCV is curable, unlike HIV and HBV. Goals of
therapy are to eradicate HCV infection to prevent hepatic cirrhosis, decompensation of cirrhosis, hepatocellular
carcinoma (HCC) and death. End point of therapy: undetectable HCV RNA in a sensitive assay (<15 Iu /ml) 12
weeks sustained virological response (SVR12) and 24 weeks (SVR24) after the end of treatment.
Aim of the Work: To assess the efficacy of DAAs in the treatment of HCV in Aswan Governorate; and to
compare between the different combinations of DAAs ± ribavirin ±interferon which were available during the
study period as regards efficacy and possible side effects in each treatment combination.
Patients and Methods: This retrospective study was conducted in Aswan Fever Hospital, Aswan Hospital
Health Insurance and Tropical Medicine Department Ain Shams University. Study population: Patients with
chronic hepatitis C who received treatment in the period from January 2015 to July 2016. Group I: Triple therapy
(Sofosbuvir + Ribavirin + Interferon) for 3 months. Group II: Sofosbuvir + Ribavirin for 6 months. Group III:
Sofosbuvir + Simeprevir for 3 months. Group IV: Sofosbuvir + daclatasvir ± Ribavirin for 3 months.
Results:
In Group I SVR was 74.3% ,Group II SVR was 60% ,Group III SVR was 85.7% and Group IV SVR
was 100% Conclusion: This is a large real-life report of the use of very low-cost generic medications for treating
HCV-G4 within the largest treatment programme worldwide. The use of entirely generic SOF DCV combination
with or without generic RBV was well tolerated and associated with high response rate in patients with different
stages of liver disease. This can be an example for other countries of similar limited resources for managing their
patients with HCV.

who were equally divided into 3 groups; 50 pregnant women with pregesational diabetes melleitus alone and
50 pregestional diabetes melleitus complicated with preeclampsia. These two groups were compared with 50
healthy pregnant women, free from medical disease, as control group. Results: In pregnant women with
pregestational DM, HbA1c should be kept below 7% and it is better to be less than 6.5% by proper glycemic
control, as higher levels of HbA1c were associated with bad perinatal outcomes in the forms of RDS, neonatal
hypoglycemia, macrosomia, IUGR, Apgar score 1 & 5min and NICU24. In addition to, bad maternal outcomes
in the forms of polyhyramnios, preterm labor, PROM, prolonged labor, mode of delivery, postpartum
hemorrage, puerperal sepsis, pulmonary embolism, preeclampsia and its complications as eclampsia, HELLP
syndrome, renal affection, hepatic affection and retinal affection. There was no significant relation between
long term maternal glycemic control (HbA1c) & the changes of blood flow velocity in the umbilical artery in
pregnancy complicated with diabetes mellitus unless the pregnancy is complicated with fetal growth restriction
or preeclampsia. Conclusion: An increased pulsatility index of umbilical Doppler was found in our study to be
the important predictor of perinatal outcome in diabetic pregnancies complicated by preeclampsia but not in
uncomplicated diabetic pregnancy.

ABSTRACT
Dengue fever is a febrile disease caused by infection from one of the four dengue virus serotypes (DENV1,
DENV2, DENV3 and DENV4). The clinical manifestations of dengue fever are broad-spectrum, ranging from
asymptomatic to life threatening, shock syndrome. Usually, the dengue virus doesn't cause neurologic
manifestations, but recently this has been documented in some cases. We report a case of dengue encephalitis in a
42- year-old gentlemen from Bangladesh who was presented with a history of altered level of consciousness
associated with headache, subjective fever, fatigue, nausea and vomiting. Blood test results of Dengue
Immunoglobulin M (IgM) antibodies and polymerase chain reaction (PCR) were positive. In addition, other causes
of encephalitis were ruled out by appropriate laboratory investigations. Dengue Encephalitis should be considered
in the differential diagnosis of fever with altered level of consciousness, especially in areas where dengue fever is
endemic.

ABSTRACT
Background: most of renal neoplasms are of epithelial origin and they are malignant. Renal cell carcinoma
(RCC) accounts for approximately 2% of all cancers. The disease resulted in more than 100,000 yearly deaths
worldwide. Histologic diagnosis of renal neoplasms is usually straight forward by routine light microscopy.
However, immunohistochemistry may be essential in several contexts, including differentiating renal from non-
renal neoplasms, differentiating subtypes of primary renal epithelial neoplasms and diagnosing rare types of renal
neoplasms or metastatic RCC in biopsy specimens. Aim of the work: multiple therapeutic options tailored to an
individual patient are now being offered. In view of these developments, availability of a robust and dependable
panel of immunohistochemical stains becomes even more important because pathologists are frequently asked to
render diagnosis on limited material. Material and methods: in this study a total number of 50 cases of some
types of renal cell tumors were immunohistochemically stained for Napsin A, CD 82 and Cyclin D1. Results:
these cases included 18 cases of ccRCC (36%), 16 cases of PRCC (32%), 8 cases of ChRCC (16%) and 8 cases of
oncocytoma (16%).Conclusion: we concluded that napsin A may be useful in differentiating between ccRCC and
PRCC (particularly type 1 which showed more vacuolated or clear cytoplasm). CD82 may be useful in
differentiating between ChRCC, which was CD82 positive and oncocytoma, which was CD82 negative. Cyclin
D1 had no significant value in the differentiation of different types of renal epithelial tumors.
Recommendation: we recommended the usage of Napsin A in differentiating between ccRCC and PRCC and
CD82 in differentiation between ChRCC and oncocytoma. More studies are needed to evaluate napsin A in
differentiating between ChRCC and oncocytoma.
Keywords:
RCC, napsin A, CD82, cyclin D1.

King Khalid hospital ­NAJRAN city - KSA
ABSTRACT
The main cause of perforation of the gallbladder is cholecystitis with or without cholelithiasis. In old age,
spontaneous perforation of gallbladder can be due to decrease in its blood supply, which can be due to
atherosclerosis, focal vasospasm or localized vasculitis. Perforation of gallbladder is associated with high
morbidity and mortality, if left untreated. Here we report a case of a 60-year-old male with perforation of
gallbladder.

ABSTRACT
Background:
Trauma remains the leading cause of death among young adults, excessive alcohol and drug
consumption are not only significant contributors to this epidemic, but are also independent predictors of injury
recidivism (repeated trauma). Patients and Methods: In the present study five hundred injured patients with
different types of injuries were randomly selected from Al-Azhar University Emergency Hospital. Trauma sheet
was done for every patient. Ten ml urine was obtained from each patient at the time of admission and before
receiving any kind of treatment whether medical or surgical. Then, toxicological screening was done for every
patient by using D-THC-123626(one step Drug of Abuse rapid test) is a uni drug panel Enzyme Immunoassay

ABSTRACT
Background:
Chronic kidney disease (CKD) is a common and growing problem worldwide; Earlier
recognition of chronic kidney disease (CKD) could slow progression, prevent complications, and reduce
cardiovascular-related outcomes. Study objective: to show the knowledge of the population Hail region on
CKD and its causes, risk factors, appropriate treatment, and consequences.
Methods: A cross sectional study carried out in Hail region during the period from 1 October to 31
December. Data was collected by personal interview using a predesigned questionnaire containing all the
relevant questions.
Results: Majority (60%) of participant have a good knowledge about CKD, 678 (71.4%) of participant think
that alcohol drinking are the most cause of CKD, 81.2% think smoking, 62.7% think DM and 60.7% think
that hypertension is the cause. Side pain are the most (84.4%) known symptom of CKD followed by difficulty
urination known in 74.4%, Oliguria in 67.8% and hypertension in 34.4%. About the risk factors of the
disease, 96.6% think that some food was the risk factors of CKD, 89.8% think about obesity, 81.5% think
about Analgesic, 56.0% think about DM and 30.5% think about positive family history of CKD. It's found
also that 85.6% of participant know that CKD 85.6% can't be treated without renal transplantation, 83.3%
with dialysis and 71.2% by drugs also large number of them know that it can be treated in high percentage.
Almost all of them say that CKD can be decreased by performing muscular exercises.
Conclusion: Current estimates of CKD awareness indicate that awareness remains unsatisfactory. Also, little
is known regarding whether increased awareness improves clinical outcomes for CKD patients. Further
research is necessary to continue to design and refine awareness campaigns aimed at dissemination of basic
CKD information, given both the high prevalence of CKD and its risk factors and the low estimated
awareness of CKD.

ABSTRACT
Background:
Adolescence refers to the developmental period between childhood and adulthood, and the WHO
defines adolescents as individuals between the ages of 10­19 years. They make up about 20% of the world
population. Rapid development and urbanization of KSA has resulted in changes in nutritional and diet patterns that
have affected the BMI of children and adolescents and led to nutritional transition. The objective of this study was
to evaluate and estimate the weight status and prevalence of underweight in school-aged male and female
adolescents in Arar city, Northern Saudi Arabia using the BMI. Methods: This was a cross-sectional study that has
been conducted among school adolescents of both sexes, aged 12-18 years during the academic year 2015­2016
over a period of 9 months (October 1st, 2015 to June 30th, 2016). Information obtained through an interviewer
administered semi-structured questionnaire. Body mass index (BMI) was calculated as per the formula BMI =
weight (kg) / height(m2). Age and sex-specific BMI percentiles were computed based on the Centre for Disease
Control (CDC)/National Centre for Health Statistics growth curves. Results: In the studied participants (n = 849),
the male-female ratio was (48.1%:51.9%). About half (50.4%) of the studied adolescents had normal BMI, 25.7%
were underweight (below the 5th percentile), 18.1% were overweight and only 5.8% were obese (above 95th
percentile). In conclusion; nutritional status among adolescents is not so well. Yet more work is needed to identify
the more influential factors which can improve the nutritional status among adolescents in Arar beside nutritional
education programs to the mothers and/or care givers.

ABSTRACT
Background:
High uric acid level used to predict many diseases including left atrial thrombus, it may
indicate aspirin-resistant patients. It could be also used as a biochemical index for diagnosing
adolescence depression. High uric acid level is a known risk factor for deterioration of renal function in
chronic kidney disease. It is also as a risk factor for cardiovascular disease and found to be associated
with increased arterial stiffness Aim: is to investigate the independent association between serum uric
acid and lipid profiles. Methods: Cross sectional study conducted over 200 patients who attended the various
out-patient department of Prince Sattam Bin Abdulaziz University Hospital Al Kharj in Saudi Arabia. The data
included individuals between 20 and 75 years old with lab test within the last year. Results: The data showed
that the highest level of uric acid was in patients older than 50 years old (394 SD ±77.77) and it decreased in
proportionate. The data showed significant association between the uric acid and the triglyceride (P = 0.003)
and no significant association with the total cholesterol (P= 0.511). It also revealed no significant differences
between the antihypertensive as well as antidiabetic groups and normal patients (P = 0.520 and 0.594
respectively). Conclusions: There is strong association between the uric acid and triglyceride, while high level
of uric acid is not associated with high level of total cholesterol. The antidiabetic as well as antihypertensive
drugs have significant effect over the triglyceride level while there is no significant effect on the TC level and
the UA.

ABSTRACT
Background:
Ultrasound scanning is noninvasive, usually painless procedure that used as the main adjuvant
modality with mammography for depiction of the breast lesions nature. It is easy-to-use and less expensive
than other imaging modalities. Besides lacking the exposure risk to ionizing radiation as in mammography, it
also provides real-time imaging, and can easily detect lesions in women with dense breasts. Conventional
ultrasound however is not free from limitation. It cannot replace annual mammography and careful clinical
breast examination. Being an operator dependent, US needs experienced radiologists as well as good
equipment to avoid misinterpretation of the lesions, and to decrease the number of false positive and false
negative results. Aim of the Work: is to detect the impact of ultrasound elastography in diagnosis of solid
breast lesions, and to evaluate its capability in differentiating benign form malignant lesions, with special
focus on: A-Evaluation of sensitivity and specificity of sonoelastography, with cyto-histological diagnosis
taken as the reference. B-Detection of the ability of sonoelastography to provide additional information on
tissue elasticity in the event of equivocal mammographic and/or sonographic findings in order to guide the
diagnostic workup towards biopsy or follow-up. Patients and methods: The present study is a prospective
research work that included 39 patients with breast lesions where elastographic ultrasound was performed
following screening or diagnostic mammography and breast ultrasound to evaluate its possible impact on
accurate diagnosis and consequent guidance for management planning. This study was performed at a
private center in the period from September 2017 to March 2018. The patients' age ranged between (24 - 72
years) with a mean of 48 years. Results: The elastography scores for different breast lesions was:Lesions
that scored 1, 2, and 3 were considered benign(30/39 cases, 77 %), whereas lesions that scored 4 and 5 (9/39
cases, 23%) were considered malignant. After revising pathology results of the 30 cases diagnosed as benign
by elastography scoring 26/30(87%) were benign (true negative) by pathology and 4/30(13%) were
malignant by pathology (false negative).After revising pathology results of the 9 cases diagnosed as
malignant by elastography scoring 7/9(82.8%) lesions confirmed to be malignant by pathology (true
positive) and 2/9(17.2%) lesions were proved to be benign by pathology (false positive).The calculated
sensitivity of elastography score was 80%, specificity was 88.9%, PPV and NPV were 82.8% and 87%
respectively, and the total accuracy was 85.3%.Conclusion: Sonoelastography is a simple, non-invasive
diagnostic technique that provides information about the stiffness of a breast masses, thus completing the
morphological assessment of B-mode ultrasound. Recommendations: Other studies are recommended to be
performed on axillary lymph nodes, to evaluate the elastographic efficacy in differentiating between reactive
and malignant pathologically enlarged axillary lymphadenopathy.

ABSTRACT
Background:
Many multiple sclerosis (MS) patients with normal peripheral hearing suffer from difficulties in
their hearing especially speech perception in background noise, which is possibly because of deficit of central
auditory processing in this group.
Objective: To elaborate the effect of MS on central auditory processing.
Subjects and methods: Seven audiologic tests including masking level difference (MLD), auditory memory
test (recognition, content and sequence), dichotic digit test (DDT), speech intelligibility in noise test (SPIN)
and gap in noise test (GIN) as well as electrophysiologic assessment (speech evoked ABR c-ABR and P300)
were used for comparing aspects of central auditory processing between MS patients and controls. Scores for
each test obtained through cross-sectional non-invasive study conducted on 30 Egyptian subjects with
relapsing-remitting MS who had mean age of 37.07 ± 11.43 years, and 30 controls with normal peripheral
hearing and mean age of 33.40 ± 9.38.
Results: This study demonstrated reduced MLD in MS at 500 & 1000 Hz in relation to controls. MS patients
were worse than controls in recognition memory (pv = 0.011), memory for contents (pv <0.001) and memory
for sequence (pv <0.001). in addition, low scores of DDT (version I & II) revealed in MS patients (pv =
<0.001& 0.011 for I & II respectively), reduced SPIN test score in MS subjects (pv<0.001), elevated threshold
and reduction of percent of correct answer obtained from GIN test in MS patients (Pv <0.001). Furthermore,
in MS patients, there were prolonged latencies and reduced amplitudes of c-ABR waves and P300. In
addition, significant differences were revealed between MS subjects and controls in all c-ABR measures
analysis.
Conclusion: this study revealed apparent effect of MS on auditory processing.
