Abstracts in International Conferences ………….. 174-176 An important part of the mission of Kasr Al Aini Faculty of Medicine, Cairo University is training a professional, specialized graduate able to conduct research and apply national and international standards of medical care. The institution should prove that academic research activities make a full contribution to the achievement of the mission. The quality and quantity of research activities should be documented. This is the third document of the published research of the faculty in international journals. The number of staff involved in peer reviewed published research is 415. We aim to increase this record by encouraging staff, especially the young generations, to publish their research in international journals with a high impact factor. The quality and quantity of research activities is an important factor in accrediting academic instutitions and ranking of universities.

Impact Factor: 1.953 Effect of dexmedetomidine on the characteristics of bupivacaine in a caudal block in pediatrics. Saadawy I, Boker A, Elshahawy MA, Almazrooa A, Melibary S, Abdellatif AA, Afifi W. Department of Anesthesia, Faculty of Medicine, Cairo University, Cairo, Egypt. Abstract Background: Dexmedetomidine (DEX) is a highly selective alpha(2)-adrenoceptor agonist that has been used increasingly in children. However, the effect of caudal DEX has not been evaluated before in children. This prospective randomized double-blinded study was designed to evaluate the analgesic efficacy of caudal DEX with bupivacaine in providing pain relief over a 24-h period. Methods: Sixty children (ASA status I) aged 1-6 years undergoing unilateral inguinal hernia repair/orchidopexy were allocated randomly to two groups (n = 30 each). Group B received a caudal injection of bupivacaine 2.5 mg/ml, 1 ml/kg; Group BD received the same dose of bupivacaine mixed with DEX 1 microg/kg during sevoflurane anesthesia. Processed electroencephalogram (bispectral index score), heart rate, blood pressure, pulse oximetry and end-tidal sevoflurane were recorded every 5 min. The characteristics of emergence, objective pain score, sedation score and quality of sleep were recorded post- operatively. Duration of analgesia and requirement for additional analgesics were noted. Results: The end-tidal sevoflurane concentration and the incidence of agitation were significantly lower in the BD group (P < 0.05). The duration of analgesia was significantly longer (P < 0.001) and the total consumption of rescue analgesic was significantly lower in Group BD compared with Group B (P < 0.01). There was no statistically significant difference in hemodynamics between both groups. However, group BD had better quality of sleep and a prolonged duration of sedation (P < 0.05). Conclusion: Caudal DEX seems to be a promising adjunct to provide excellent analgesia without side effects over a 24-h period. It has the advantage of keeping the patients calm for a prolonged time. Implications statement: Caudally administered DEX (1 microg/kg), combined with bupivacaine, was associated with an extended duration of post-operative pain relief. 1 International Publications Aesthetic Plast Surg. 2009 May;33(3):461-70. Mammaplasty: the "super flap" or the superior pedicle extra long flap for massive breasts with marked ptosis or gigantomastia. Gheita A. Department of Plastic Surgery, Faculty of Medicine, Cairo University, Cairo, Egypt. Abstract Background: Very large breasts associated with ptosis frequently present a challenge to the plastic surgeon in choosing the ideal procedure to obtain a satisfactory result. A free nipple graft, which for many represents the best option in these conditions, has many disadvantages. Methods: The author's method of a superior pedicle flap allows for very long flaps, in some cases over 40 cm and breast ptosis with the nipple at more than 55 cm from the suprasterna notch with preservation of the circulation to the nipple-areola complex. This procedure has been developed and modified from the French oblique method of Dufourmentel and Mouly converted to an inverted T, while the glandular resection is performed in a keel fashion behind the areola to house and give room for these very long flaps without undue compression on them and endangering the blood supply to the areola-nipple complex. Results: The method is described in detail, the early and late results presented, and advantages and disadvantages discussed. It has stood the test of time as it has been used regularly for more than 20 years and has become our standard method. CONCLUSION: The method presented is especially suitable for very large breasts with ptosis; however, excellent results are also achieved for all other degrees of ptosis, with very little modification in the procedure needed to suit different breast sizes and shapes. Most of the time we obtain a pleasing and attractive breast. This method rarely resulted in complications and never required a blood transfusion. 2 International Publications Am J Med Genet A. 2010 Jan;152A(1):169-74. Severe cleidocranial dysplasia and hypophosphatasia in a child with microdeletion of the C-terminal region of RUNX2. El-Gharbawy AH, Peeden JN Jr, Lachman RS, Graham JM Jr, Moore SR, Rimoin DL. Faculty of Medicine, Cairo University, Egypt. Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia due to mutations causing haploinsufficiency of RUNX2, an osteoblast transcription factor specific for bone and cartilage. The classic form of CCD is characterized by delayed closure of the fontanels, hypoplastic or aplastic clavicles and dental anomalies. Clinical reports suggest that a subset of patients with CCD have skeletal changes which mimic hypophosphatasia (HPP). Mutations in RUNX2 are detected in approximately 65% of cases of CCD, and microdeletions occur in 13%. We present clinical and radiological features in a 6-year-old child with severe CCD manifested by absence of the clavicles marked calvarial hypomineralization، osteoporosis and progressive kyphoscoliosis. HPP .features included Bowdler spurs، severe osteopenia, and low alkaline phosphatase Following negative mutation analysis of RUNX2, comparative genomic hybridization (CGH) microarray was performed. The result revealed a microdeletion in RUNX2, disrupting the C-terminal part of the gene. 3 International Publications Am J Hosp Palliat Care. 2009 Feb-Mar;26(1):52-6. Hospitalization pattern in a hospital-based palliative care program: an example from Saudi Arabia. Alsirafy SA, Hassan AA, Al-Shahri MZ. Palliative Care Medicine Section, King Faisal Cancer Centre, King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia. Palliative Care Medicine Unit, Clinical Oncology Department, Faculty of Medicine, Cairo University, Cairo, Egypt. Abstract The few palliative care programs available to date in Saudi Arabia are largely hospital- based. Subacute palliative care models have not been developed yet. This retrospective review was conducted to assess the patterns and outcomes of hospital-based palliative care unit admissions in the absence of subacute palliative care models. We reviewed 759 eligible palliative care unit admissions related to 629 cancer patients during a 4-year period. Of all admissions, 66% were hospitalized through the emergency room. The average hospital stay was 24 days. The majority (86%) of patients died in-hospital. These results suggest that end-of-life quality indicators are unlikely to improve depending on hospital-based palliative care models only. To improve palliative care services in Saudi Arabia, other subacute models may need to be considered. 4 International Publications Am J Hosp Palliat Care. 2009 Dec-2010 Jan;26(6):502-3.

Impact Factor: 1.36 Effect of severe stress on the gastric motor activity: canine study of mechanism of action. Shafik A, Shafik AA, El Sibai O, Shafik IA. Department of Surgery and Experimental Research, Faculty of Medicine, Cairo University, Cairo, Egypt. Abstract Background: Increased gastric motility was observed during restraint stress in animals; however, mechanism of action could not be traced in literature. We investigated the hypothesis that high levels of stressful cutaneous stimuli induce increase of gastric motor activity through a reflex action. Methods: Gastric tone (GT) was assessed in 14 dogs by barostat system consisting of balloon-ended tube connected to strain gauge and air-injection system. Tube was introduced into stomach and its balloon inflated with 150 mL of air. Thermal cutaneous stimulation (TCS) was performed by thermal plate applied to skin. Temperature was raised in increments of 5 degrees
