Ask ChatGPT about the research
جرت هذه الدراسة على 78 مريضاً و تم تقييم نتائجها من خلال 57 مـنهم اسـتمروا فـي المتابعة، خضعوا جميعاً لعملية جراحة جيوب تنظيرية بسبب إصابتهم بداء البوليبات الأنفية المتعدد (Polyposis nasal) ، بالتهاب جيوب مزمن (sinusitis chronic) . و قد تـم تطبيـق مادة الميتومايسين c في نهاية العمل الجراحي داخل إحدى الحفرتين الأنفيتين الخاضـعتين للجراحة و كانت دائماً اليسرى و قد اعتمد بروتوكول مشابه لبروتوكول مجرى فـي دراسـة عالمية حديثة مع تعمد تطبيق المادة الدوائية بالتركيز نفسه الموصى به و إنما لفترة أطول. كما أنه في دراستنا خلافاً للدراسة الأخرى فقد جرى اختبار تأثير هذه المـادة أيضـاً فـي المرضى الخاضعين لعمل جراحي بسبب إصابتهم بداء البوليبات الأنفية، و هو الأكثر مشاهدة لدينا من بين الأمراض المعالجة بجراحة الجيوب التنظيرية. و قد خلصت هذه الدراسة إلى تأكيد فائدة هذه المادة الدوائية و لا سيما فيما يتعلق بإنقاصـها لاحتمال النكس في داء البوليبات الأنفية و تشكل التندبات و الالتصاقات المرضـية و تضـيق فتحات الجيوب. كما خلصت أيضاً إلى بعض النتائج الأخرى التي يمكن أن تعود بالفائدة على هذه الجراحة و مجال استخدام هذه المادة فيها.

To evaluate the role of Endoscopic Sinus Surgery ( ESS ) in excision of inverted
papillomas , and to compare the recurrence rate in this approache with that of external one .
Background: Assessment of new surgical technique in the management of the most important benign
para-nasal sinuses tumor.
Gastroesophageal reflux is one of the most common diseases in the world and his
most important symptoms is the heartburn. He requires surgical treatment in some
advanced cases.
The study was performed on 20 patients who underwent laparoscopic anti
-reflux
surgery in Al-Assad and tishreen university hospitals in Lattakia between 2011-2017 and
were followed for at least six months after surgery.
The analysis of the results showed a complete efficacy of this surgery in terms of
absence of clinical symptoms in patients and no need for medical treatment after surgery,
Absence of major complications and temporary swallowing only in 15% of cases.
Comparison with other studies has shown similar results in terms of effectiveness
and complications.
As a result of the study, we concluded that this surgery is low risk, highly effective,
and has few complications.
laparoscopic cholecystectomy has many features that make it preferable to open
surgery with a low incidence of complications.
The study was conducted on 877 patients who underwent laparoscopic
cholecystectomy at Al-Assad and Tishreen hospitals in
the period 2010-2017
The surgical method used and the reasons for conversion to open surgery were
studied in addition to the complications occurring during or after the surgery in terms of
occurrence rate and method of management of complications and the results of this
management.
The average age of patients was 46 years, the proportion of females was 64.5%, the
mean surgical time was 45 minutes.
The ratio of conversion to open surgery was 2.05% and the most common cause was
severe inflammation, "unclear calot`s triangle" and suspicion of malignancy.
Partial laparoscopic cholecystectomy was performed in 1.36% of cases and
peroperative complications occurred in 0.34% of cases and postoperative complications in
2.16% of cases.
Analysis of the results revealed that the rates of conversion for open surgery and the
incidence of complications are within the internationally accepted rates and that the results
of management of complications were satisfactory and consistent with the methods used
globally to manage complications.
We concluded that this surgery is safe and its complications are rare. We recommend
applying it in our hospitals . We have suggested some recommendations that can reduce
the complications of this surgery.
Real-world applications often require improved models by leveraging *a range of cheap incidental supervision signals*. These could include partial labels, noisy labels, knowledge-based constraints, and cross-domain or cross-task annotations -- all ha
ving statistical associations with gold annotations but not exactly the same. However, we currently lack a principled way to measure the benefits of these signals to a given target task, and the common practice of evaluating these benefits is through exhaustive experiments with various models and hyperparameters. This paper studies whether we can, *in a single framework, quantify the benefits of various types of incidental signals for a given target task without going through combinatorial experiments*. We propose a unified PAC-Bayesian motivated informativeness measure, PABI, that characterizes the uncertainty reduction provided by incidental supervision signals. We demonstrate PABI's effectiveness by quantifying the value added by various types of incidental signals to sequence tagging tasks. Experiments on named entity recognition (NER) and question answering (QA) show that PABI's predictions correlate well with learning performance, providing a promising way to determine, ahead of learning, which supervision signals would be beneficial.
we have started applying assisted thoracoscopic surgery (VATS) in AL-ASSAD
University hospital in Damascus in 1992 and we achieved in a period past 332
different operations, most of them were done under general anesthesia, only 48
cases were done
under local, due to the risk of general anesthesia. The age of
patients varied between 13-72 year.
