من أجل تقييم طريقة الوقاية المناعية بالاستشراب المنـاعي ICT و المعتمـدة علـى المستضـد 38Kda للمتطفرة الدرنية، جمعت العينات من ٢٤٥ شخصاً منهم ١١١ لديهم تدرن رئـوي و ٦٩ تدرناً خارج رئوي و ٦٥ شخصاً كمجموعة ضابطة (٢٥ مريضاً بأمراض رئوية غير التدرن، و ١٠ مرضى بأمراض غير رئوية و غير التدرن، و ٣٠ شخصاً سليماً). و قد وضع التشخيص بناء علـى المعطيات السريرية و الأشعة و لطاخة القشع و التشريح المرضي. و أُجرِي لجميع العينات الفحـص المصلي ICT و كانت النتائج كالتالي: عند مرضى التدرن إيجابيي اللطاخة كان اختبار الـ ICT إيجابيـاً عنـد ٥٠ مـن ٥٥ مريضـاً (الحساسية ٩١ (% و عند مرضى التـدرن الرئـوي سـلبيي اللطاخـة كانـت الحساسـية ٨٦ % (٤٨/٥٦ ،( و بلغت حساسية الاختبار ٧٤ % عند مرضى التدرن خارج الرئوي (٥١/٦٩ . ( و كانـت حساسية الاختبار عند مرضى التدرن بشكل عام ٨٣ % أما نوعية اختبار الـ ICDT فقد بلغـت ٩٦ % عند مرضى بأمراض رئوية غير التدرن، و ١٠٠ % عند الأشخاص الأصحاء.
To evaluate the rapid immuno-chromotographic assay ICT based on antigen 38 Kda of Mycobacterium tuberculosis, sera was collected from 245 persons, 111 of them were pulmonary TB patients, 69 extrapulmonary, 25 having non TP respiratory diseases, and 30 healthy control persons. The diagnosis were based on usual testes such as signs and symptoms, X-ray, smear and biopsy as well as the using of the serological test ICT the results were as follows: When pulmonary TB smear positive ICT was positive in 50 of 55 patients (sensitivity 91%) whereas in pulmonary TB smear negative, sensitivity of ICT was 86 % (48/ 56). The sensitivity of the assay in extra-pulmonary TB patients was 74% (51/69) and the sensitivity of the test in all TB types was 83% (149/ 180) and specificity of the test in nonTB pulmonary diseases were 96% and 100%in healthy persons.

Recently, it has been noticed that the incidence of pulmonary hypertension
in Neonatal Intensive Care Unit of children hospital has increased.
The purpose of this study is to evaluate the outcome of newborns with
pulmonary hypertension. This study
was conducted on 73 newborns
diagnosed by Doppler Echocardiography, admitted to the unit from 1/7/02
to 1/7/03.
High rates of hypoxia and sepsis were noticed during the perinatal period.
Treatment included good oxygenation, dopamine, alkalosis and diuretics.
The results were asThe following: complete recovery in 76.7%, Partial
improvement in12.3% and death in 11%.
The last tow results were discussed and due to otheer organic lesions
prevented the full recovery or led to death.
The selection of recording material is an important factor to be considered in
making interocclusal records. Many materials are available to record interocclusal relations , but they
differs in their accuracy during mounting the casts on the articu
lator.
Purpose: The purpose of the study was to compare of four interocclusal recording materials in their effect
on the relationship of the casts, and to determine the most accurate material.
COPD is a major public health problem , and it results with an extensive social and
economical burden on both the patient and his family on one hand and the healthcare
system on the other . Despite the great advances in the management of patients w
ith COPD
, the use of the optimal treatment of the proposed treatment options is still being discussed ,
and Must achieve greater benefit for both patients and the healthcare system .
This research is designed to study and compare the effect of the combination
(salbutamol and ipratropium bromide) with the effect of salbutamol alone in the treatment
of patients with stable COPD , by studying and comparing the improvement in the forced
expiratory volume in the first second (FEV1) and in forced vital capacity
( FVC) after a month of a treatment .
The study included 80 patients (53 males and 27 females), the patients were between
45-81 years of age , 63 patients were smokers and 17 were nonsmokers.
The study showed that after a month on therapy , for patients treated with the
combination (salbutamol + ipratropium bromide) the increasing in FEV1 was 0.35 liters
and in FVC was 0.61-liter , while , for the patients treated with salbutamol alone , the
increasing in FEV1 was 0.28 liters and FVC was 0.48-liter .
We concluded that a combination of ipratropium bromide and salbutamol is more
effective at improving pulmonary function than salbutamol alone.
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital
anomaly. It presents predominantly in infancy with features of myocardial ischemia or cardiac failure and
may be mistaken for common pediatric cond
itions such as colic, reflux or bronchiolitis. With early
surgical correction the prognosis is good. In this report we present unusual case of a 5-year-old female
with an anomalous left coronary artery arising from the pulmonary artery (ALCAPA) presenting with
chest pain,dyspnea and palpitation during physical exertion.Trans-thoracic echocardiography and
coronary angiography revealed an anomalous origin of the left coronary artery with mitral regurgitation .
She subsequently underwent successful surgical technique where the left internal thoracic(mammary)
artery was used to revascularise the left main coronary artery which is considered as the first unique
procedure in children. Excellent surgical results were obtained and the patient was discharged from the
hospital without complaints.
Tuberculosis is still a worldwide disease. Medical treatment is essential but
surgery still has a role in the diagnosis and treatment of several various thoracic tuberculous lesions (both
pulmonary and extra-pulmonary).
We aim to present and analy
zethe results of surgical treatment of thoracic tuberculous cases in Al-Assad
University Hospital in Damascus. Also, we purpose to determine the indications of thoracoscopic and
traditional surgical interventions in this field, and studying their complications.
