Background& Objective: pemphigus vulgaris is a life threatening relapsing disease, the first line in its treatment is systemic steroids, and due to the high rate of side effects caused by systemic steroids in pemphigus vulgaris patients ,some immunosuppressant drugs have been introduced as an adjuvant steroid sparing agents , and one of these immunosuppressants is azathioprine, which is the most used drug by therapists, but this use was due to experience and not due to strict studies , this research studies the relationship between azathioprine and relapse in pemphigus vulgaris patients during the prednisolone reduction period. Materials & Methods: 70 pemphigus vulgaris patients have been studied, from the patients of the dermatology university hospital during the period between 1/8/2008 -29/5/2011 (the first year for collecting the sample and the rest for follow-up) they have been divided into 2 groups. The first: were treated with prednisolone plus azathioprine (30 patients ), the second : were treated with prednisolone alone (40 patients ).and after the control of the disease the dose of prednisolone was reduced gradually ,till it was stopped, and patients were observed for relapse. Results: there was no meaningful statistical difference between the two groups in the terms of relapse, as giving azathioprine did not reduce the relapse rate, and did not reduce the prednisolone dose needed to prevent relapse. Conclusion: in this study no use of azathioprine in preventing relapse in pemphigus vulgaris patients, so we advise for more studies to confirm that, and to give more attention during its prescription.

Research summary
تتناول هذه الدراسة دور الأزاثيوبرين في منع النكس خلال فترة تخفيض البريدنيزولون عند مرضى الفقاع الشائع. الفقاع الشائع هو مرض مناعي مهدد للحياة، ويعتبر البريدنيزولون العلاج الأول له. نظراً للتأثيرات الجانبية للبريدنيزولون، تم استخدام الأزاثيوبرين كدواء مساعد لتقليل الحاجة للبريدنيزولون. شملت الدراسة 70 مريضاً تم تقسيمهم إلى مجموعتين: الأولى تلقت البريدنيزولون مع الأزاثيوبرين، والثانية تلقت البريدنيزولون فقط. بعد السيطرة على المرض، تم تخفيض جرعة البريدنيزولون تدريجياً حتى الإيقاف، وتمت متابعة المرضى لرصد حدوث النكس. أظهرت النتائج عدم وجود فارق إحصائي ذي مغزى بين المجموعتين من حيث النكس، مما يعني أن الأزاثيوبرين لم يقلل من نسبة النكس أو من جرعة البريدنيزولون اللازمة لمنع النكس. توصي الدراسة بإجراء المزيد من الدراسات لتأكيد هذه النتائج والحذر عند استخدام الأزاثيوبرين.
Critical review
دراسة نقدية: على الرغم من أن الدراسة قدمت نتائج مهمة حول عدم فعالية الأزاثيوبرين في منع النكس عند مرضى الفقاع الشائع، إلا أنها لم تتناول بشكل كافٍ التأثيرات الجانبية للأزاثيوبرين والتي قد تكون ذات أهمية كبيرة في اتخاذ قرار استخدامه. كما أن الدراسة لم تذكر تفاصيل كافية عن العوامل الأخرى التي قد تؤثر على نتائج العلاج مثل العمر، الجنس، وشدة المرض عند البدء بالعلاج. من المهم أيضاً أن تكون هناك دراسات مقارنة مع أدوية أخرى مثبطة للمناعة لمعرفة ما إذا كان هناك بدائل أكثر فعالية وأقل تأثيرات جانبية. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر شمولاً إذا تضمنت مجموعة أكبر من المرضى ومدة متابعة أطول.

Pephigus vulgaris is a recurrent life threatening disease. Its basic treatment is systemic steroids, after treating the first attack of the disease by systemic steroids we start to reduce the dose of the steroids gradually. During this reduction th e desease may flare up, this recurrence is routinely treated by increasing the dose of the steroids again to control the disease, this study was made to compare the benefits of tetracycline in controlling the recurrence of pemphigus vulgaris with the routinely used way which is elevating the dose of prednisolone.
pemphigus vulgaris is a life threatening relapsing disease, the first line in its treatment is systemic steroids, and due to the high rate of side effects caused by systemic steroids in pemphigus vulgaris patients, some immunosuppressant drugs have been introduced as an adjuvant steroid sparing agents, and one of these immunosuppressants is methotrexate, and in spite of the lack of its use in pemphigus vulgaris, a few studies have shown an encouraging results of its use, and have advised to carry out more studies about it as an immunosuppressant which has been omitted from usage in pemphigus vulgaris for a long time.

This study included 232 patient with acne between the ages of 12 and 38 years old. Acne vulgaris was graded using Global Acne Grading System (GAGS). This study was undertaken to detect the impact of acne vulgaris and related factors that may influe nce the quality of life (QoL). QoL was measured using a combination of skin disease-specific (Dermatological Life Quality Index (DLQI)) and acne-specific (Cardiff Acne Disability Index (CADI)) questionnaires. The results showed significant impairment of QoL in acne patients , females were more affected than the males, there was no association between age and quality of life impairment and the impact was proportional to the severity of acne, more severe acne is associated with greater effect on quality of life.
Background: cancer patients experience large physical and emotional challenges related to side effects of chemotherapy drugs, which make coping and adaptation essential issue for coping with disease. Aim: this study was conducted to identify coping strategies among cancer patients during chemotherapy and its relation with patient's age and gender Methods: data were collected from 150 patients from Tishreen university hospital by using brief coping questionnaire in addition to demographical sheet Results : the results revealed that cancer patients tend to use various coping strategies which are problemfocused and emotional- focused, reflected positive and negative coping. The most used coping strategies were active coping strategy (78.66%), followed by seeking social support for instrumental reasons strategy (76.66%), followed by planning strategy (76%), then focus on and venting of emotions (75.33%), followed by acceptance strategy (70.66%), then seeking social support for emotional reasons (68%), then turning to religion (58%). Also results showed that coping strategies changed according to age and gender changing (p < 0.05) where women tend to use emotional- focused coping strategies while aged patients prefer emotional social support and acceptance. Conclusion: emotional issues for cancer patients during chemotherapy require more concern with ongoing assessment for adaptation and coping strategies, for designing appropriate interventions agreed with coping behaviors which cancer patients demonstrate during treatment.
