Aim: We investigated the relationship between the severity of reciprocal ST depression and the extent of coronary artery disease in patients with inferior myocardial infarction. Method: Ninety-five consecutive patients (52 women 43 men, with a mean age of 54±5 years) who had acute inferior myocardial infarction were included in the study. Reciprocal changes in the ST segment were defined as ST depression of> 1 mm in at least two out of four of the precordial leads V1-V4. All the patients had undergone coronary angiography within seven days of admission. The extension of coronary artery disease which was measured by Gensini and Reardon scores, was compared with the reciprocal changes on ECG recorded at the time of admission. Result: There was a significant correlation between reciprocal ST depression and disease extension (r=0.68 for Gensini score, r= 0.88 for Reardon score, p< 0.05 for both). Conclusion: The presence of ST segment depression in the precordial leads during the acute inferior myocardial infarction was associated with greater myocardial necrosis and more frequent left coronary artery disease.

We report a case of a very long left main coronary artery (58 mm) with septal perforators before bifurcation. The coronary arteries were seen clear of plaques. To the best of our knowledge, this case is very rare because of the existence of the first and second septal perforator arteries originating from a very long left main coronary artery.

Purpose: Heart is affected structurally and functionally in end-stage renal disease (ESRD). However, the data available about adverse effects of ESRD on right ventricle (RV) is scarce. We aimed to evaluate echocardiographic parameters of RV in nondiabetic, normotensive patients with ESRD undergoing hemodialysis (HD)., Methods: A total of 45 (24 women; mean age 52.4 ± 12.4 years) consecutive nondiabetic, normotensive patients with ESRD undergoing HD and 39 healthy age and sex-matched control subjects (22 women; mean age 50.3 ± 6.6 years) were enrolled in the study. M-mode and two dimensional images, color, pulsed and continuous wave Doppler, and tissue Doppler measurements were acquired from all subjects. Echocardiographic evaluation was performed in the days between HD dates of the patients., Results: RV fractional area change, tricuspid annular plane systolic excursion, tricuspid E velocity, E/A ratio, tricuspid annular E´ velocity, and E´/A´ ratio were lower in patients than controls (p < 0.001, p = 0.003, p = 0.007, p = 0.005, p < 0.001, and p = 0.034, respectively). However, RV diastolic area, RV myocardial performance index, E/E´ ratio, and mean and systolic pulmonary artery pressure were higher in patients than controls (p < 0.001, p = 0.007, p = 0.005, p < 0.001, p = 0.006, respectively)., Conclusions: RV systolic and diastolic functions of nondiabetic, normotensive HD patients are deteriorated as compared to healthy controls.

Recovery of the ventricular function in a patient with cardiomyopathy is very rare. Autoimmune polyendocrine syndrome is also very rare. We herein report a case of reversed cardiomyopathy associated with autoimmune polyendocrine syndrome type II (Schmidt's syndrome) composed of Addison's disease, vitiligo and Hashimoto's thyroiditis. The ventricular function and size were reversed following the administration of suitable hormone replacement therapy for polyendocrine syndrome.

Objectives. To investigate insulin-like growth factor I (IGF-1) levels in response to hyperbaric oxygen therapy (HBOT) for diabetic foot ulcers and to determine whether IGF-1 is a predictive indicator of wound healing in patients with diabetic foot ulcers. Design and Methods. We treated 48 consecutive patients with diabetic foot ulcers with HBOT. Alterations of IGF-1 levels in patients whose wound healed with HBOT were compared with those in patients who did not benefit from HBOT. Results. There was no significant difference in initial IGF-1 levels between the two groups (P = 0.399). The mean IGF-1 level increased with HBOT (P < 0.05). In the healed group, the mean IGF-1 increase and the final values were significantly higher (P < 0.05). In the nonhealed group, the mean IGF-1 increase was minus and the final values were not significantly different (P < 0.05). The increase in IGF-1 level with HBOT was significantly higher in the healed group (P < 0.001). Conclusions. IGF-1 increased significantly in the healed group. We believe that HBOT is effective in the treatment of diabetic foot ulcers, with an elevation of IGF-1. This alteration seems to be a predictive factor for wound healing in diabetic foot ulcers treated with HBOT.

Background: Crimean-Congo hemorrhagic fever (CCHF) involves the multi-organ systems. The involvement of the heart in adult patients has been described previously. We investigated the electrocardiographic and echocardiographic findings of pediatric patients with CCHF., Material/methods: Patients younger than 16 years of age diagnosed with CCHF were enrolled in the study. The diagnosis of CCHF infection was based upon typical clinical and epidemiological findings and serological tests. All patients underwent a thorough cardiologic evaluation. A standard 12-lead electrocardiography and echocardiography were performed., Results: Twenty-three consecutive patients who were hospitalized with diagnosis of CCHF were enrolled in the study (mean age: 12±2 years, 6 female). All electrocardiographic parameters were within normal ranges according to age. Seven patients (30%) had minimal (<1 cm) pericardial effusion. Fifteen (65%) patients had segmental wall motion abnormalities (hypokinesia). A second echocardiography revealed that all wall motion abnormalities had disappeared; the pericardial effusion persisted in only 2 of 7 patients (28%)., Conclusions: Cardiac involvement appears to be more frequent in children with CCHF disease than in adults, but it is slighter and almost totally reversible; however, the course of the disease in children is milder than it is in adults.

Background: Pseudoexfoliation syndrome (PEX) is recognised by chronic deposition of abnormal pseudoexfoliation material on anterior segment structures of the eye, especially the anterior lens capsule. In recent years, several studies have shown the presence of vascular, cardiac and other organ pseudoexfoliative material in patients with ocular pseudoexfoliation., Aims: The purpose of this study is to determine whether an association exists between ocular pseudoexfoliation and coronary artery disease, aortic aneurysms and peripheric vascular disease., Patients and Methods: 490 patients who underwent coronary angiography (CAG) at Kosuyolu Cardiovascula Research and Training Hospital were included in the study. Patients were evaluated for conventional risk factors such as age, sex, family history, hypertension, diabetes, dislipidemia and smoking. Detailed eye examinations including evaluation of lens were done in all patients. The presence of PEX material in the anterior segment was best appreciated by slit lamp after pupillary dilation. The patients were divided into two groups according to the presence of PEX, and compared for the presence of CAD and other risk factors., Results: CAD was present in 387 patients. 103 patients had normal coronary angiography. 20 (5.2 %) of CAD patients and 4 (3.9%) of normal CAG patients were found to have PEX (p>0.05). There was no significant relationship between CAD and the presence of PEX (p>0.05). When patients were grouped according to the presence of PEX, only age was significantly different between the two groups (r: 0.25, p<0.001)., Conclusion: There is no significant relationship between the presence of PEX and CAD. Further studies in larger scales with elderly population may be more valuable.

Background: Elevated Gamma-glutamyltransferase (GGT) level is independently correlated with conditions associatedwith increased atherosclerosis, such as obesity, elevated serum cholesterol, high blood pressure and myocardial infarction. It is also demonstrated that serum gamma-glutamyltransferase activity is an independent risk factor for myocardial infarction and cardiac death in patients with coronary artery disease. Although the relationship between gamma-glutamyltransferase and coronary artery disease has been reported, not many studies have shown the relationship between changes ofgamma-glutamyltransferase in acute coronary syndromes and a well established coronary risk factor high sensitive C-reactive protein. (hs-CRP)., Aims: In this study, how gamma-glutamyltransferase levels changed in acute coronary syndromes and its relationship with high sensitive C-reactive protein if any were studied. PATIENTS #ENTITYSTARTX00026;, Methods: This trial was carried out at Kosuyolu Cardiovascular Training and Research Hospital and Van Yuksek Ihtisas Hospital, Turkey. 219 patients (177 males and 42 females) presenting with acute coronary syndrome, and 51 control subjects between September 2007 and September 2008 were included in the study. Serum gamma-glutamyltransferase, high sensitive C-reactive protein, serum lipoprotein levels and troponin I were determined., Results: Serum gamma-glutamyltransferase and high sensitive C-reactive protein levels were higher in acute coronary syndrome patients compared to control. There was also correlation between gamma-glutamyltransferase and high sensitive C-reactive protein levels., Conclusion: Serum gamma-glutamyltransferase and high sensitive C-reactive protein levels were higher in acute coronary syndrome patients. In subgroup analyses, the higher difference with Non-ST elevation myocardial infarction and ST elevation myocardial infarction groups than unstable angina oectoris group proposes a relationship between gamma-glutamyltransferase and severity of acute coronary syndromes.

The treatment of implant-related infections is troublesome. This study was conducted to compare the effectiveness of three different surgical modalities in the treatment of implant-related infection. A total of 32 Wistar albino rats were randomised into four groups after the establishment of implant-related infection: no treatment, surgical débridement, antibiotic-loaded bone cement and antibiotic-loaded autogenous bone. Microbiological colony counts were made at the sixth week in order to evaluate the effectiveness of of the treatments. The antibiotic-loaded bone cement group revealed superior results compared with the other groups in terms of reduction of microbiological colonies. Three animals in the bone cement group revealed extensive infection. Although antibiotic-loaded bone cement showed superiority over other treatment modalities, it should be employed after an unsuccessful trial of débridement because of the risk of extensive infection.

Objectives: This study was designed to determine the in vitro antibacterial activity of gentamicin- or teicoplanin-impregnated human cancellous bone as a local antibiotic carrier., Methods: The study samples were obtained from human cancellous bone within the femur head in seven patients who underwent partial or total hip arthroplasty. Bone specimens were processed and incubated with gentamicin or teicoplanin for an hour. Control bone specimens were soaked in sterile saline solution for the same duration. Antibiotic release of bone specimens was assessed by the disc diffusion technique after 1, 3, 7, 10, 14. 18, and 21 days of antibiotic impregnation, with seven samples in each group. The test strains were E. coli ATCC 25922 for gentamicin, and S. aureus ATCC 25923 for teicoplanin. In vitro antibiotic efficacy was defined as an inhibition zone diameter of = or >15 mm for gentamicin, and = or >14 mm for teicoplanin., Results: Evaluation of inhibition zone diameters showed that bone-teicoplanin complexes had a longer duration of antibiotic release than that of bone-gentamicin complexes (12 to 18 days vs 7 to 10 days). There was no inhibition in the control group. There were no significant differences in inhibition zone diameters of teicoplanin- and gentamicin-treated specimens on the first and third days; however, teicoplanin exhibited significantly greater zone diameters on the seventh (p=0.008) and tenth (p=0.003) days., Conclusion: Our data show that, under appropriate conditions, human cancellous bone incorporates a considerable amount of teicoplanin and exhibits effective antibiotic release for approximately two weeks.

Simultaneous bilateral quadriceps tendon rupture is a very rare injury mostly seen in patients with chronic renal failure or other systemic chronic diseases. Metabolic acidosis in chronic renal failure predisposes these patients to tendon degeneration. A 37-year-old woman who received hemodialysis for chronic renal failure for two years presented with complaints of severe pain in the left hip and inability to walk. She had a history of two consecutive falls in the past two months. On physical examination, there were joint spaces in both suprapatellar areas, active extension of both knees was inhibited, and movements of the left hip were quite painful. Knee ultrasonography and magnetic resonance imaging showed bilateral quadriceps tendon rupture from patellar attachment. At surgery, full-thickness quadriceps tendon tears were repaired with Tycron transpatellar suture anchors. Internal fixation was not considered for hip fracture due to the presence of chronic renal failure, so hemiarthroplasty with bipolar endoprosthesis was performed in the same session for femoral neck fracture. Six months after the operation, the patient was able to walk without support and almost regained her normal knee functions.

Matrix metalloproteinases (MMPs) are involved in the regulation of the extracellular matrix (ECM) of the myocardium and thus the pathogenesis of vascular and cardiac hypertrophy. In this study, we investigated contribution of plasma matrix metalloproteinases to development of left ventricular hypertrophy (LVH) and diastolic dysfunction in hypertensive subjects. Hypertensive patients with (n = 27) and without LVH (n = 23) were included. All participants underwent a complete transthoracic echocardiographic examination, including recordings of the mitral annular early, late, systolic and diastolic velocities by Doppler imaging. Plasma concentrations of MMP-3 and MMP-9 were determined by the one-step sandwich enzyme immunoassay method. Plasma MMP-3 and MMP-9 concentrations were significantly higher in patients with LVH than those without LVH (2.4 +/- 1.2 vs 1.5 +/- 0.7 ng/ml, p = 0.006 and 5.2 +/- 2.8 vs 3.3 +/- 1.7 ng/ml, p = 0.003, respectively). MMP-3 and MMP-9 levels were also correlated with left ventricular posterior wall thickness and Doppler indices of diastolic dysfunction. Our findings have suggested that increased MMP levels may contribute to LVH and left ventricular diastolic dysfunction. Therefore, treatment of hypertension with MMP lowering drugs, such as angiotensin converting enzyme inhibitors and angiotensin receptor blockers, may have favorable effects on LVH and left ventricular diastolic dysfunction.

Open and arthroscopic surgical techniques are used to treat shoulder instability. There may be various reasons of failure related to these techniques, the understanding of which may increase success rates. In this paper, we evaluated the factors associated with failure in open and arthroscopic surgical repairs of anterior, posterior, and multidirectional instability, together with possible solutions.
