Antibiyotikli kemik çimentosunun 0 ve 15. günlerde mekanik dayanımı: Surgical Simplex P kemik çimentosu ve teikoplanin ile biyomekanik çalışma
(Türk Ortopedi ve Travmatoloji Derneği, 2002) Göğüş, Abdullah; Akman, Şenol; Göksan, Bora S.; Bozdağ, Ergün
Amaç: Mekanik dayanım açısından 40 gr belirli bir kemik çimentosuna katılabilecek belirli bir antibiyotiğin maksimum dozu "0. gün" ve antibiyotik salınımı sonrası "15. gün" için araştırıldı. Çalışma planı: 40 g Surgical Simplex P kemik çimentosuna 0, 400, 800,1200,1600, 2000, 3200 ve 4000 mg teikoplanin katılarak sekiz deney grubu oluşturuldu. Kompresyon ve dört nokta eğme mekanik dayanım testleri için üçüncü kuşak sement hazırlama ve uygulama koşullarında örnekler elde edildi. Her bir konsantrasyon için "0. gün" ve "15. gün" için 10'ar örnek oluşturuldu. Örneklerin mekanik dayanım testleri ASTM ve ISO standartlarına göre "0. gün" ve 37∘ C su banyosunda antibiyotik salınımı sonrası "15. gün"de yapıldı. Değişik antibiyotik konsantrasyonları 0 mg kontrol grubu ile, ayrıca aynı antibiyotik konsantrasyonlarının 0. gün ve 15. gün mekanik test sonuçları karşılaştırıldı. Sonuçlar: Kompresyon testlerinde "0. gün" grubu içinde anlamlı farklılık bulunmadı; "15. gün" grubunda ise 800 mg'den itibaren anlamlı dayanım azalması saptandı. Her iki grupta tüm konsantrasyonlarda elde edilen mekanik dayanım değerleri ASTM alt limiti olan 70 MPa'nın üzerindeydi. Dört nokta eğme testinde "0. gün" grubunda 1200 mg'den itibaren, "15. gün" grubunda ise 400 mg'den itibaren anlamlı dayanım azalması saptandı. "15. gün" grubundan 4000 mg ISO'nun alt limiti olan 50 MPa'nın altında kalırken, 3200 ve 2000 mg gruplarında 50 MPa'ya çok yakın sonuçlar elde edildi. Çıkarımlar: Deney sonuçları, üçüncü kuşak çimento hazırlama ve uygulama koşullarında, 40 gr Surgical Simplex P kemik çimentosuna güvenle katılabilecek en yüksek teikoplanin dozunun 1600 mg olduğunu gösterdi.

Cervical spine injuries in children
(2004) Hamzaoglu, A.; Mirzanli, C.
Cervical spine injuries in children and adolescents are rare. Common mechanisms include motor vehicle accidents, sports injuries, fall from height, and gunshot injuries. Cervical spine injuries are classified by Allen and Ferguson according to the period they occur, as infantile, early juvenile, and late juvenile. Anatomically, two main types are defined as occipitoatlantal (upper cervical) and subaxial injuries. The purpose of this paper is to review cervical spine injuries in children and adolescents with respect to epidemiology, injury mechanisms, diagnosis, clinical and radiologic aspects, and treatment in the light of the current literature.

Coronary bypass surgery in octogenarians
(2001) Arbatli, H.; Unal, M.; Demirsoy, E.; Tansal, S.; Yagan, N.; Tükenmez, F.; Sener, D.
OBJECTIVE: The age of the patients referred for coronary bypass surgery is getting older progressively. Early and late postoperative outcome of octogenarians were evaluated and compared with younger age group in this study. METHODS: Records of 55 patients aged 80 years or older (mean age 82.7 +/- 2.8) among 3834 patients, who had coronary bypass graft procedure, operated between 1995 and 2001 were reviewed retrospectively. RESULTS: There were 39 men (70.9%) and 16 women (29.1%). Three patients had aortic valve replacement, 1 had left ventricular aneurysm repair, 1 had carotid endarterectomy additionally. Atrial fibrillation (21.8%), renal dysfunction (16.4%), and prolonged ventilation (10.9%) were the prominent complications. The hospital mortality rate was 7.27% (4 patients). Kaplan Meier Survival Analysis estimated that at the end of 5 years 83.1 + 5.2% of patients were still alive. CONCLUSION: Coronary bypass operations can be performed in octogenarians with slightly increased but acceptable hospital mortality and longer hospital stay. Early intervention and individual modifications in cardiopulmonary bypass techniques may improve the results in this patient population.

The effects of phase II cardiac rehabilitation programme on patients undergone coronary bypass surgery
(2005) Çiftçi, C.; Duman, B.S.; Çağatay, P.; Demiroğlu, C.; Aytekin, V.
Objective: To investigate the effects of phase II cardiac rehabilitation in 52 patients undergone coronary artery bypass surgery. Methods: Gradual walking tests, cardio-pulmonary capacity tests and lipid profile were administered to patients selected for phase II cardiac rehabilitation before and after the programme. Training was started on 12-channel electrocardiogram controlled running bands 3 times a week for 20 min periods for 12 weeks fitting the programme. Low or intermediate level exercise programme was applied to patients. Cleveland Clinic Chronotropic Assessment exercise protocol was used during rehabilitation. Results: As a result of phase II cardiac rehabilitation administered to 52 patients undergone coronary bypass operation, exercise capacity, oxygen consumption, anaerobic threshold, cardiac output mean values (p?0.001) and mean HDL cholesterol level (p?0.05) were found to increase, whereas body mass index, total cholesterol, LDL cholesterol and triglyceride mean levels reduced (p?0.001) significantly. Conclusion: In patients who have undergone coronary bypass surgery, phase II cardiac rehabilitation is a very useful programme in improvement of life quality and secondary prevention.

Hip fracture-dislocation (Pipkin type IV) associated with an apparent traumatic aortic valve rupture. Case history
(2001) Gögüş, A.; Akpinar, S.; Unal, M.; Sönmez, B.; Hamzaoglu, A.
Traumatic aortic valve rupture with resultant aortic insufficiency is a rare complication of blunt trauma. Here reported is a case with a posterior fracture-dislocation of the hip (Pipkin type-IV) and an undisplaced sternum fracture who developed hemodynamic instability in the clinical follow-up and was diagnosed having a traumatic aortic valve rupture using echocardiography. He first was treated with a biological valve replacement. Two weeks later a total hip arthroplasty combined with the osteosynthesis of the posterior wall of the acetabulum was performed. Sternum fracture healed conservatively. In multiply injured patients especially with a blunt thorax trauma hemodynamic instability despite appropriate fluid replacement should rise the suspicion of cardiac injuries, especially traumatic aortic valve rupture. Echocardiography is a simple but reliable method for the diagnosis.

Mechanical strength of antibiotic-impregnated bone cement on Day 0 and Day 15: a biomechanical study with Surgical Simplex P and teicoplanin
(2002) Gögüş, A.; Akman, S.; Göksan, S.B.; Bozdag, E.
OBJECTIVES: To determine the maximum amount of a specific antibiotic added to 40 g acrylic bone cement in terms of the effect on mechanical properties of the bone cement on Day 0 and after antibiotic release on Day 15. METHODS: In an experimental design, eight teicoplanin doses (0, 400 mg, 800 mg, 1200 mg, 1600 mg, 2000 mg, 3200 mg and 4000 mg) were added to bone cement (Surgical Simplex P). Specimens were prepared using the third generation cementing technique to determine the compressive strength and four-point bending strength according to ASTM and ISO standards, respectively. For each concentration, 10 samples were prepared for Day 0 and Day 15. Mechanical tests were performed on Day 0 and after antibiotic leaching in water at 37 degrees C on Day 15. 0 mg specimens served as controls and mechanical strengths for each antibiotic concentration on Day 0 and Day 15 were compared. RESULTS: In compression tests, Day 0 samples showed no significant differences, whereas Day 15 samples starting with 800 mg exhibited significant decreases in compressive strength. However, the compressive strengths were above the minimum standard of 70 MPa set by ASTM at all concentrations and in all groups. Four-point bending tests demonstrated significant decreases in strength starting with 1200 mg in Day 0 samples, and with 400 mg in Day 15 samples. Four-point bending strengths of 2000 mg, 3200 mg, and 4000 mg samples decreased below, or approximated closely the minimum standard of 50 MPa set by ISO on Day 15. CONCLUSION: Our results suggest that the maximum amount of teicoplanin dose to be safely added to 40 g of Surgical Simplex P is 1600 mg when third generation cement mixing and application techniques are employed.

The surgical treatment of atrial fibrillation
(Turkish Soc Cardiology, 2007) Akpınar, Belhhan; Sağbaş, Ertan; Güden, Mustafa; Sanisoğlu, İlhan
The surgical treatment of atrial fibrillation (AF) has entered a new era with the development of new tools and advanced techniques. The Maze III operation remains as the gold standard for the surgical treatment of AF. However new energy sources have been adopted for treating this arrhythmia in an effort to reduce the invasiveness and technical concerns with the original procedure. Success rates ranging between 70-98% have been reported using these new techniques. On the other hand interventional cardiologists have further improved their techniques so that percutaneous techniques are competing with minimally invasive ablation techniques for the treatment of drug resistant and symptomatic lone AF. These developments have aroused the interest of cardiac surgeons in AF surgery and have found themselves a wide application. It has been estimated that thirty thousand patients have undergone surgical ablation for AF so far. Inevitably procedure related complications have occurred and caused skepticism by some groups. However surgical ablation has become a widely accepted treatment modality for AF patients undergoing concomitant cardiac surgery. The aim of this text is to make an overall review of the surgical treatment of AF and evaluate the current situation in view of the literature and the personal experience of the authors.
