ABSTRACT

Background: Cardiac resynchronization therapy (CRT) is now an established effective treatment
for patients with advanced heart failure.
One approach to improve CRT outcome may be determination of the degree of dsynchrony before
CRT as a predictor for CRT response. Conversely, the focus may be on an improved positioning of
CRT left ventricular (LV) lead.
AIM of the study: We aimed at our study to define the rule of three-dimensional
echocardiography in determining the optimal site of LV pacing lead.
Patients and Methods: The current study was conducted on 30 patients with heart failure who
had received CRT in Ain Shams University Hospitals in the period from 2012 to 2014.
All patients were subjected to thorough history taking, complete general and local examination,
conventional 2D echo and 3D echo analysis. The latest wall to reach the minimal volume was
determined. The patients were classified after CRT insertion into group A with concordance
between the delayed LV area and LV lead position and group B with discordance between them.
Our patients were followed up for 6 months duration.
Results
: Our findings demonstrated that the response to CRT resulted in improvement of
NYHA class (p-value 0.04), LV EF by 2D and 3D echocardiography (P value <0.001 for both)
with significant increase in LV 3D SV (p value 0.001), and significant reduction of LA
diameter (p-value 0.03), LVESD diameter, 2D and 2D LVESV (P value 0.026, 0.026
respectively)
, however there was no any statistically significant difference between both
groups.
Conclusions: No additional benefit of selecting LV lead position pre CRT insertion to be
concordant with the latest myocardial segment in reaching the minimal systolic volume assessed
by 3D echocardiography

ABSTRACT
Background: Esfenvelerate a synthetic pyrethroid insecticide, is widely used in the home environment and
in agriculture because of its high activity against a broad spectrum of insect pests and its low animal
toxicity .Objective of this study was to evaluate the genotoxicity of esfenvelerate and the possible
protective role of curcumin against this genotoxicity. Material and methods:Forty male albino rats were
divided into 8 groups of 5 rats each: G1 served as control and G2 served as positive control received
(100mg/kg curcumin ), G3,G4 and G5 were orally administrated with (1/20 LD50, 1/40 LD50 and 1/60
LD50 of esfenvelerate ) respectively and the last three groups(G6,G7and G8) were received the same doses
of pesticide plus 100mg /kg curcumin for 28 days daily. Animals were sacrificed and bone marrow samples
were collected for chromosomal aberration assay test and liver samples were used for DNA damage
detection by comet assay. Results:chromosome aberration assay revealed that all the tested doses induced
chromosomal aberrations (CA) such as centromeric gaps, chromatid gaps, chromatid deletion, dicentric
chromosome, and ring chromosome. The alkaline comet assay showed significantly increased tail moment,
tail length and tailed DNA % in liver cells of animals treated with esfenvelerate alone compared to control
group. On the other hand, oral curcumin significantly ameliorated the genotoxicity induced by esfenvelrat.
All these results clarified the efficacy of curcumin in amelioration of chromosomal aberrations of
structures as well as DNA damage which may result from its antioxidant properties.

ABSTRACT
Background: Crohn's disease and ulcerative colitis evolve with a relapsing and remitting
course. Determination of inflammatory state is crucial for the assessment of disease activity and
for tailoring therapy .Computed tomography enterography (CTE) has become a main modality for
the evaluation of inflammatory bowel disease (IBD). It simultaneously offers visualization of the
small bowel and extra intestinal status, which is helpful for diagnosing IBD. Crohn disease has
long segmental enhancing wall thickening related with the eccentric longitudinal distribution. In
addition, mural stratification, fibrofatty proliferation, positive comb sign by increased mesenteric
vascularity and internal/perianal fistula are characteristics of Crohn disease and can be identified
on CTE. Each of CTE findings for the IBDs is helpful for differential diagnosis. The main
disadvantage of this technique is the requisite radiation exposure of patients, particularly in young
patients. However, recent development of advanced CT techniques is promising for radiation
dose reduction without compromising diagnostic image quality

ABSTRACT

Background: Pediculosis capitis (PC) and scabies are an important public health problem in
childhood. They have a worldwide distribution. Also, they have many effects on the infested students.
Objectives: To define the prevalence of PC and scabies, to find out the socio-demographic,
environment, and health care behavior risk factors, and to determine the effects on the studied students
in Cairo, Egypt. Subjects and Methods: A cross-section, analytical study design was chosen to
conduct this work. Three primary schools were the field of this study. Total number of the students
was 1987. The students were clinically examined; for each infested case with PC and/ or scabies a
control student was chosen. Results: Prevalence of PC and scabies was 10.2% and 3.4%, respectively.
These infestations were more common significantly among students in the public school. Significant
social risk factors of infested students were the low level of head of the family education, occupation,
and social status. Also, significant personal hygiene risk factors were poor hair, body, and environment
hygiene. While significant health care behavior risk factors were student never received skin
examination, no early consultation for skin diseases, and no compliance with therapy. Also; female
gender, the last birth order child, had previous infestation with PC, had sibling(s) with PC, and had
parents with history of infestation with PC were significant risk factors. On the other hand; male
gender, the last birth order child, had previous infestation with scabies, had sibling(s) with scabies, and
had parents with history of infestation with scabies were significant risk factors. Further, the PC cases
with crowding index >1, had no sun access, had shared water supply and bathing facilities, co-
sleeping, had no short cut hair, and sharing hair brushes were significant risk factors. On the other
hand, the scabitcs with crowding index >1, had no sun access, had shared water supply and bathing
facilities, and co-sleeping were significant risk factors. Lastly, presences of psychiatric, sleep, and
peers' relations disturbances were significantly more common among the infested students.
Conclusions: Many risk factors of PC and scabies can be manipulated, so these infestations can be
prevented, so many health hazards on the students could be prevented. Recommendations: Improving
students' hygiene, health education, and regular dermatological screening and treatment of students are
important essentiality. Also, dermatological health component should be integrated in school health
program. Lastly, further studies in different rural and urban areas in Egypt are recommended.

ABSTRACT:
Background:
tuberculosis (TB) is a multisystem disease with myriad presentations and manifestations
that may be pulmonary or extra-pulmonary. It is the most common cause of infectious diseases related
mortality worldwide. Mechanisms underlying host defense to TB infection are poorly understood.
Adiponectin is a protein produced exclusively in adipose tissue; it is lower in obese subjects than their
lean counterparts. Another adipocyte hormone is leptin which is higher with fat mass and body mass
index (BMI). Wasting is a known feature of TB with a decrease in BMI. Patients with pulmonary TB
disease often suffer from weight loss and BMI and leptin are known to be inversely correlated with
adiponectin. Thus, increased adiponectin may be a promising marker for severity of the disease
independent of the BMI and leptin.
Aims of the work: the work aimed to evaluate the levels of serum adiponectin in patients with pulmonary
TB in both active and latent TB patients as a diagnostic marker for tuberculous inflammation. Also, levels
of serum leptin and measured BMI were evaluated and compared to make a relationship among active
TB, latent TB, and healthy control groups.
Subjects and Methods: the subjects were divided into 3 equal groups. The 1st group included 25 patients
with active pulmonary TB. The 2nd group included 25 patients with latent TB after 6 months of diagnosis.
The 3rd group included 25 healthy control volunteers. Serum levels of adiponectin and leptin were
measured and BMI values were calculated to all groups.
Results: Serum adiponectin levels in patients with active pulmonary TB were very highly significantly
increased compared to both latent TB patients and healthy subjects (P<0.0001), while serum adiponectin
levels in patients with latent pulmonary TB were only significantly increased compared to the healthy
subjects (P<0.05). On the other hand, serum leptin levels in patients with active pulmonary TB were very
highly significantly decreased compared to both latent TB patients and healthy subjects (P<0.0001), while
serum leptin levels in patients with latent pulmonary TB were only significantly decreased compared to
the healthy subjects (P<0.05). Also, BMI in patients with active pulmonary TB were very highly
significantly decreased compared to both latent TB patients and healthy subjects (P<0.001), while BMI in
patients with latent pulmonary TB were only significantly decreased compared to the healthy subjects
(P<0.05).
Conclusion: the higher levels of adiponectin with lower levels of leptin in association with lower BMI
measurements might indicate activity and severity of the TB disease. On the other hand, the lower levels
of adiponectin with higher levels of leptin in association with higher BMI measurements might indicate
stability and latency of the TB disease. Thus, increased adiponectin in the serum of pulmonary TB
patients may be promising markers for severity of the disease independent of the BMI and leptin levels.
Key words: TB patients, leptin, adiponectin, body mass index.

ABSTRACT
Aim of the work:
bisphenol A (BPA) is a synthetic monomer that is polymerized to manufacture
polycarbonate plastic products and resins, including those used in food packaging and dental sealants.
It is used in the manufacture of a great variety of products including: compact disks, food can linings,
plastic windows, car parts, adhesives, protective coatings and powder paints. This work aimed to
study the effect of prenatal exposure to BPA on the endometrium of female rats.
Materials and methods: thirty adult female albino rats were divided into three groups: rats in group 1
served as a control (G1) and received an equal amount of sesame oil to those of the treated groups;
those in group 2 (G2) were administered by gavage 5.0 g BPA/kg/day (low-dose group); the third
group (G3) received 50 g BPA/kg/day (high-dose group). The female offspring of each group were
weaned at day 21 and maintained until 3 months old. The uteri were dissected for the histological and
immuno-histochemical examination.
Results: low-dose group showed degeneration of the epithelial lining of the endometrium with focal
patches of increased epithelial cell layers. The high dose group revealed cytoplasmic hydropic
degeneration and pyknotic nuclei of the epithelial cells. Estrogen receptors showed a significant
decrease of positive cells in low dose treated group and this decrease markedly accentuated in the
high dose one. Positive nuclei for Ki-67 were markedly increased with increasing doses of BPA.
Conclusion: BPA showed obvious endometrial degenerative and proliferative histological changes.
Therefore, the use of this substance in food packaging materials and in the manufacture of substances
liable to come into contact with food and drink should be phased out.

ABSTRACT

Background: Osteoarthritis (OA) is the most common type of arthritis. It is a degenerative joint
disease. OA is usually defined according to radiographic changes. Conventional radiographs (CR)
were considered the most relevant outcome measure to assess the progression of OA in clinical
trials and epidemiological studies. Many modalities are used in treatment of knee OA. There is a
distinct need for new procedures that are cost effective by reducing the need for pharmaceutical
and surgical management, while targeting the biochemical process of OA. Platelet-rich plasma
(PRP) is one of these new procedures. PRP was found to increase hyaluronic acid (HA)
concentration, stabilizing angiogenesis in patients with osteoarthritic knees.
Aim of the study: Was to assess the value of intra articular injection of autologous platelet rich
plasma in management of knee osteoarthritis.
Patients and methods: This study was conducted on 40 patients with primary knee osteoarthritis,
divided into 2 groups; study group treated with 3 injections of PRP, and control group treated
with single dosed high-molecular weight HA. Clinical assessment and visual analogue scale
(VAS) scoring were done pretreatment and 3 months post treatment.
Results: Clinical improvement and reduction of VAS in both groups which is significant at the
study group. Conclusion: PRP injection could be considered as a simple, safe, effective and non-
palliative treatment that may promote cartilage healing in knee osteoarthritis as it improve the
clinical condition and the function of the joint. Hence, it may represent a useful addition to the
available therapeutic options for knee osteoarthritis.

ABSTRACT
Background
High salt intake induces renal-stress. The present study was carried out to examine the therapeutic
effects of proximol(Halfa bar extract), lasilactonedrug(Spironolactone+Furosemide) and their
combination on renal-stressed rats.
Material and Methods:Thirty five male rats were used and divided into five groups. The first group
served as negative control and received fresh tap water orally for four weeks. The animals in the
other four groups drank hypertonic saline solution (2% NaCl) as a sole source of drinking water for
four weeks to induce the animal model of renal stress. Then the renal-stressed rats were further
divided into: positive control, renal-stressed rats treated daily with proximol (7.8 mg/kg b.wt), renal-
stressed rats treated daily with lasilactone (3.9 mg/kg b.wt), and renal- stressed rats treated daily
with a combination of proximol and lasilactone for four weeks. The levels of aldosterone, sodium,
potassium, calcium, urea, uric acid and creatinine were measured in the sera of rats. Nitric oxide
(NO), reduced glutathione (GSH) and lipid peroxidation (MDA) levels were also measured in the
homogenate of renal tissue.
Results:In the renal-stressed group, there was a significant increase in levels of aldosterone, sodium,
calcium, urea, uric acid, NO and MDA and a significant decrease in potassium and GSH as
compared to control group. Although the treatment of renal stressed rats with proximol, lasilactone
and their combination reduced the increased level of aldosterone induced in renal stressed rats,
aldosterone level was still higher than the control value. In addition, the treatment with proximol,
lasilactone and their combination restored the significant increase in sodium, NO and lipid
peroxidation to non significant changes as compared to control group. Also the decreased levels of
GSH induced in renal-stressed rats returned to non significant changes. However, potassium
decreased significantly below the control and the model groups with the combined treatment.
Furthermore, treatment with proximol, lasilactone and their combination reduced the elevated levels
of uric acid and urea induced by hypertonic saline solution to control- like values in the case of uric
acid and to a significant decrease in the case of urea.
Conclusion:In conclusion, proximol, lasilactone and their combination have an effective role in
ameliorating the changes in the levels of aldosterone, serum electrolytes, oxidative stress and
consequently the disturbance in kidney functions in renal-stressed rats induced by hypertonic saline
solution.
Keywords: renal-stressed rats, proximol, lasilactone, aldosterone, electrolytes, oxidative stress.

ABSTRACT
Background:
Carbamazepine "CBZ" (Tegretol) is an anticonvulsant and mood stabilizing drug used
primarily in the treatment of epilepsy and bipolar disorder, as well as trigeminal neuralgia. It has been
assigned to pregnancy category D by the U.S Food and Drug Administration (FDA). CBZ can cause
fetal harm when administered to pregnant women. Epidemiological data suggested that there may be an
association between the use of CBZ during pregnancy and congenital malformations, specifically spina
bifida and developmental disorders. The possible malformation-specific risks with CBZ use during
pregnancy need to be considered, so the present work was conducted to evaluate the genotoxicity of two
doses of CBZ (3.6 mg and 10.8 mg/ 100g body weight/ day) in pregnant female rats and their fetuses.
Chromosomal aberration in bone marrow cells and histopathological examination of liver and kidney of
pregnant rats were also determined. Materials and Methods: Fourty five pregnant Sprague Dawley rats
were randomly divided into the groups. The first was administered oral doses of distilled water and
served as control. The other two groups were administered oral doses of CBZ suspended in distilled
water equivalent to 3.6 mg and 10.8 mg/100g body weight/day respectively for 15 day from the 6th day
to the 20th day of gestation. Females were sacrificed on the 20th day of gestation. Results:
Administration of CBZ 3.6 mg and 10.8 mg /100g body weight to pregnant rats from the 6th till the
20thday of gestation. Decreased fetal body weight, crown-rump length, increased resorbed and dead
fetuses were observed compared to the control ones. Moreover, CBZ-high dose group(10.8mg/100g)
causedmalformations that could be described as severe growth retardation. At the same time, bone
marrow metaphases of CBZ-treated pregnant rats revealed structural chromosomal aberrations.
Whereas, histopathological examination of liver and kidney of pregnant rats treated with both doses of
CBZshowed cellular alterations.Conclusion:It has been found that usage of antiepileptic CBZ during
gestational period may create risk, associated with maternal toxicity, hepato- and nephrotoxicity and
chromosomal aberrations in pregnant rats, with intrauterine growth retardation which was manifested by
low body weight, length reduction and malformations. These alterations were dose dependent. The
benefits of taking CBZ must be weighed against the potential risks to boththe developing fetus and the
mother.
