المجد لنا نحن طلاب الطب الذين نسير بين الناس ، ونحمل حزننا بصمت في دواخلنا، لنا نحن الذين نرى تراكم المعلومات قد فاق من قدرتنا، لنا نحن الذين نحمل هم الدراسة ونخشى من عدم تجاوزها، لنا نحن الذين أحبطتنا العثرات فيها،
سلامٌ على قلوبنا، ما أعظمنا ونحن فى أرفع وأعظم علمٍ بعد علم الفقه والعقيده ،إن ربنا الذى خلق الحزن والهم والسقوط ،خلق أيضا الفرح والفرج والنهوض...
إن شاء الله سنتجاوز كل موقف وربنا لا ينسى أبدا ليالينا الحالكة تحت الضغط والتعب النفسي ...لا ينسى حَمْلنا للهم وكثرة التفكير الذى كاد يذهب بالعقل ...ولكن حاشاه أن يضيع عمل عاملٍ أبدا ..سبحانه عظيم يجزى بالإحسان إحسانا ..ولا يضيع علينا قدر حبة من خردل من تعبنا ...💛

أجوبة مختصرة للواجبات محاضرة دكتورة انتظار
للاحتياط اذا تجي
Q1/Write about the genetic and immunlogiclal factors contributing to severe covid-19 ?
-Genetic factors, age, comorbidities, hyperactive immune response, vitamin D deficiency, and prior exposure to related coronaviruses are all potential contributors to the severity of COVID-19 infections. However, not all individuals with these risk factors will develop severe disease, and other factors may also play a role.
Q2/How does COVID- 19 affect smell loss (anosmia)? And have symptoms of smell distribution changes as the virus evolved?
-COVID-19 can cause a loss of smell or changes in the sense of smell, and it is thought to be related to the virus's ability to infect cells in the nasal cavity. There is some evidence to suggest that the severity of anosmia may be a predictor of the severity of COVID-19, but it is unclear whether the symptoms of smell loss have changed as the virus has evolved.

Prevention and Control of mycobacteria tuberculosis
بصورة اسهل ومختصرة لان بالمحاضرة مطولة..
1.Prompt and effective treatment of active tuberculosis patients, along with follow-up of their contacts, is crucial to control the spread of tuberculosis.
2.Treating asymptomatic tuberculin-positive individuals with drug therapy reduces reactivation of the infection.
3.Factors that reduce host resistance, such as starvation, gastrectomy, and immune suppression, increase the risk of developing tuberculosis. HIV infection is a significant risk factor for tuberculosis.
4.Vaccination with BCG can induce resistance to tuberculosis, but available vaccines have limitations.
5.Eradication of tuberculosis in cattle and pasteurization of milk have greatly reduced M bovis infections.
