Atherosclerosis and Liver Function Tests in Coronary Angiography Patients.

OBJECTIVE: Elevated aminotransferase levels indicating liver function, even in the normal range, have attracted great concern as potential novel markers of cardiovascular risk assessment. We hypothesized the possibility that liver function test variations in the normal range might be meaningfully associated to coronary artery disease (CAD). METHOD: Eighty-eight patients were randomly selected from those who underwent coronary angiography from June 2010 to June 2011 after applying to the outpatient cardiology clinic in Gulhane Military Medical Academy. According to the results of angiographies, patients were classified into three groups as normal, non-critical (< 50% involvement in coronaries), and critical (≥ 50% involvement in coronaries). In addition to angiographic intervention, measurements of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations, albumin and the other serum parameters were performed in all patients. RESULTS: The patient groups of CAD were balanced (28 critical cases, 30 non-critical cases and 30 normal cases). Mean age was 51.93 ± 9.3 (range 32-65) years and 19.3 per cent (n = 17) were females. Multiple linear regression analysis of all three liver function tests explained a significant portion of the variance, but adjusted r-squares were small (AST = 0.174, ALT = 0.242, albumin = 0.124). Albumin was significantly higher for patients with critical CAD than for patients with no CAD (beta = 3.205, p = 0.002). Non-critical CAD was not significantly different from no CAD for any of the dependent variables. Mean AST was significantly higher for patients taking aspirin (beta = 0.218, p = 0.049), as was mean ALT (beta = 0.264, p = 0.015). CONCLUSION: Alanine aminotransferase and AST may not be associated with angiographically determined coronary atherosclerosis. Albumin may be more sensitive to demonstrate the burden of atherosclerosis. These results indicate that the association between the liver function tests and coronary atherosclerosis may be more complex than generally appreciated.

To study the correlation between carrier status of nasal Staphylococcus aureus in patients on haemodialysis with hepatitis C, hepatitis B and their sociodemographic features.

AIM: To study the correlation of nasal Staphylococcus aureus carrier status in patients on haemodialysis, infected by hepatitis C virus (HCV), hepatitis B virus (HBV), and their sociodemographic features. SUBJECTS AND METHODS: A survey, including patients' sociodemographic features, was applied to patients by physicians in face to face interviews. Medical records regarding their serologic data were recorded from haemodialysis centres. Nasal swab samples of 2 cm depth from both nostrils of patients were obtained for nasal culture. Samples were inoculated in 5% sheep blood agar and incubated in an incubator at a temperature of 37 degrees C for 24 hours. The results were studied by the same microbiologist. RESULTS: A total of 185 patients were enrolled in the study. According to culture results, 14.1% of patients (n = 26) had methicillin sensitive Staphylococcus aureus (MSSA) and 1.1% (n = 2) had methicillin resistant Staphylococcus aureus (MRSA). Status of viral hepatitis was 3.8% (n = 8), 10.8% (n = 20) for HBV and HCV respectively. Forty per cent (n = 8) of patients with HBV (+) had MSSA carrier status. Statistically significant positive correlation between MSSA and HCV carrier was detected (r = 0.325, p = 0.001) but not between HBV carrier and MSSA (p = 0.255). CONCLUSION: In the present study, significant positivity was detected between MSSA carrier status and HCV in patients on haemodialysis and who have lived together with < or = 2 family members at home. Particularly, statistically significant correlation between HCV(+) and MSSA carrier was observed.

Physician scarcity in underdeveloped areas of Turkey: what do new graduate physicians think?

INTRODUCTION: A sufficient and balanced distribution of physicians plays a key role in access to high quality healthcare services. However, this issue presents serious problems globally. Turkey is currently experiencing physician shortages, with insufficient numbers of physicians in its rural and underdeveloped areas. The objectives of this study were to identify the views of new graduate physicians, prior to employment, on working in underdeveloped areas, in order to discover factors impacting their desire to work in these areas, and to show the actual geographic distribution of physicians in Turkey. This provides the basis for discussing future policies. METHODS: This study was conducted in Turkey from September to November 2009. All physicians (N=4753) who graduated in 2009 were included in the study via online questionnaires. The response rate was 78%. Variables potentially related to physicians' decisions to work in underdeveloped areas were analyzed using the χ(2) test. To discover the imbalance in geographic distribution of physicians, data collected by the Turkish Ministry of Health (MoH) were re-analyzed. Physician density was calculated for the six zones determined by the MoH according to socioeconomic development. RESULTS: Of the physicians who participated, 52.5% were male and 13.5% expressed a desire to work in underdeveloped areas. Male physicians were more likely to work in underdeveloped areas (17.5% and 9.1%, respectively; p<0.05). There was a significant relationship between desire to work in underdeveloped areas, regions of longest stay and birthplace (p<0.05). Physicians who had lived for a significant period in areas with a high number of underdeveloped cities (Southeastern and Eastern Turkey) and those who were born in underdeveloped cities were more likely to wish to work in these areas. The most influential factor for working in these areas was higher salaries. CONCLUSIONS: Physicians who have particular socioeconomic backgrounds such as rural origin and lower background-family income are more likely to have be motivated to work in underdeveloped areas. They are also more likely to accept work in these areas if financial and non-financial opportunities are provided. The findings of this study provide guidance for those revising health workforce policies.

Volatile solvent abuse caused glomerulopathy and tubulopathy in street children.

Substance misuse among street children is a significant problem in developing countries. Volatile substances are the most abused agents. According to case reports, chronic renal diseases are common among substance-abusing street children. In this study, we examined the renal findings of 42 volatile substance-abusing street children and compared them with results from 49 healthy children (control). The street children's weight, height, and blood pressure were lower than the controls' (P < 0.05). However, their blood alkaline phosphatase and creatinine phosphokinase levels were higher (P < 0.05), and total blood protein, creatinine, and phosphorus levels were lower than the controls' (P < 0.05). Furthermore, the street children's glomerular filtration rates were within normal limits (P < 0.05), their urinary N-acetyl-beta-glucosaminidase (NAG), beta(2)-microglobulin, microalbumin, protein, calcium, phosphorus, sodium, potassium, and chloride excretions were higher, and tubular phosphate reabsorption were lower than the controls' (P < 0.05). Volatile substances have been charged with causing distal tubular disease, but increased urinary protein, NAG, beta(2)-microglobulin, microalbumin, and electrolyte excretions also result from glomerular, proximal, and distal tubular influences. We believe that increased volatile substance products in the renal parenchyma are responsible for glomerular and tubular damage. Volatile substance-abusing street children should be examined for glomerular and proximal tubular function and distal tubular acidosis.

Congenital subclavian aortic steal syndrome: hypoplastic aortic arch with severe coarctation of the aorta of unusual location.

An unusual case of subclavian-aortic steal syndrome in a pediatric patient with hypoplastic aortic arch with coarctation of the aorta of unusual location is described. Aortography showed hypoplasia of the arcus aorta and severe coarctation proximal to the left subclavian artery associated with an aneurysm formation on the isthmus and descending aorta. The enlargement of the arcus aorta was accomplished by prosthetic patch aortoplasty extending from the ascending to descending aorta via median sternotomy using cardiopulmonary bypass and moderate hypothermia. Postoperatively, the patient is doing well with equalized blood pressure.

Giant congenital coronary artery fistula to left superior vena cava and right atrium with compression of left pulmonary vein simulating cor triatriatum--diagnostic value of magnetic resonance imaging.

A 3-year-old girl with a continuous murmur on auscultation was found to have left coronary artery to right atrial fistula simulating cor triatriatum sinister on echocardiography. Coronary angiography of the patient was also insufficient to clarify the exact pathologic anatomy. Magnetic resonance imaging showed that the main drainage of the aneurysmal coronary artery was to the left superior vena cava, resulting in a diffuse arteriovenous fistula in the lower lobe of the left lung by compressing its pulmonary vein.

Infantile lobar emphysema and tracheal bronchus in a patient with congenital heart disease.

A 7-month-old girl was admitted with severe respiratory distress. Chest roentgenogram showed hyperinflation of the right middle lobe and mediastinal shift. Bronchogram showed tracheal lobe displaced superiorly by the hyperinflated right middle lobe. Echocardiography showed left-to-right shunt at the ventricular level. The patient responded well after surgical correction of cardiac defect. Four years after the operation, computed tomography examinations showed no evidence of emphysema.

Congenital coronary arteriovenous fistula in a ten-year-old boy with angina pectoris.

Congenital arteriovenous fistula (CAVF) is a rare cardiac lesion. Angina pectoris is uncommon in younger patients with CAVF. Fistula-related symptoms, complications of this anomaly and surgical complications have a strong correlation with the age of the patient. A ten-year-old male patient with angina pectoris in whom the diagnosis of CAVF was established, and who, following surgical ligation recovered, is presented.

Follow-up results of synthetic vascular grafts in children undergoing hemodialysis.

Polytetrafluoroethylene (PTFE) grafts were inserted in the thigh of 14 children (7 boys and 7 girls, age 12 +/- 1.8 years) who were undergoing chronic hemodialysis for endstage renal disease. Removal of grafts was necessary in three patients within three months of implantation. In a fourth case it was indicated in the fifteenth month. In two cases thrombectomy was necessary. Echocardiography was performed in 10 patients before and three and 12 months after surgery. Cardiac performance followed by echocardiography did not change after one year. After two years the survival of grafts was 71%. It appears that synthetic grafts offer advantages for pediatric hemodialysis patients with arteriovenous fistula failure. On the other hand, this technique entails serious risks.

Transcatheter embolization of a residual congenital coronary arteriovenous fistula with a detachable balloon; superiority of interventional cardiology?

A ten-year-old girl who presented with a continuous murmur was diagnosed with a right coronary to right ventricular fistula with colored Doppler echocardiography and selective arteriography. She underwent traditional treatment-ligation of the fistula by sternotomy. Afterwards, the systolic component of the murmur persisted and repeat arteriography showed a residual shunt through the fistula, with no change in the diameter of the right coronary artery. We describe the first case in which a residual fistula was treated with a detachable balloon embolization.

Transcatheter closure of the ductus arteriosus in children and young adults.

Transcatheter occlusion of persistent patent ductus arteriosus (PDA) was attempted in 32 patients (22 female and 10 male, mean age 5.12 +/- 3.98 years, range 9 months to 19.2 years) using Rashkind's occluder device (USCI). Implantation of a second occluder device was attempted in three of the patients. Device embolization to a pulmonary artery occurred in three patients, all with the 12 mm occluder device; two of these devices were retrieved by grabber catheter and the last with thoracotomy without adverse sequelae. Embolization to the right atrium occurred in another patient during a second device implantation attempt because of fluoroscopy problems; this patient required open-heart surgery with sequala of 2 (+) tricuspid insufficiency. In another patient with a significant shunt after the implantation of a 17 mm occluder device, mechanical hemolysis developed, but surgical intervention was not required. The overall complication rate was five out of 35 implantation procedures (14.3%). Besides these, sublingual nifedipine was required for two patients whose systolic blood pressure exceeded 160 mmHg just after the implantation procedure. Sixteen 12 mm and fifteen 17 mm occluder devices were successfully and uneventfully implanted in the first procedure, except for two patients in whom a 17 mm occluder device was implanted after retrieval of an embolized 12 mm occluder. Overall early and mid-term complete occlusion was achieved in 24 patients (75%). Complete occlusion of PDA in the first days after the procedure was achieved in all patients, with the narrowest ductal diameter of less-than 3 mm with the 12 mm occluder device, and less than 6 mm with the 17 mm occluder device.(ABSTRACT TRUNCATED AT 250 WORDS)

Sexual dysfunction assessment and hormonal correlations in patients with polycystic ovary syndrome.

In this controlled study, we aimed to evaluate the sexual dysfunction of patients with polycystic ovary syndrome (PCOS) in comparison to healthy controls. We enrolled 64 sexually active women in our study. The PCOS group consisted of 32 women who met the Rotterdam diagnostic criteria, and the control group was composed of 32 age-matched, healthy females. In addition to the demographic and clinical characteristics of the participants, the hormonal and biochemical parameters were also studied. All patients were invited to fill out the female sexual function index (FSFI) and Beck's Depression Inventory questionnaires. The prevalence of sexual dysfunction in the PCOS group was similar to controls (25% vs 19%; P=0.54). No significant difference was found according to each domain score of FSFI. Significant negative correlations were found between the total FSFI scores of the PCOS group and the total (r=-0.278) and free testosterone (r=-0.493) levels. Although depressive scores of PCOS patients were higher, they did not show greater impaired sexual functions than age-matched controls according to their FSFI scores. Considering the multifactorial state of female sexual dysfunction, further studies are needed to clarify the impact of PCOS upon sexuality.

Women with polycystic ovary syndrome have increased plasma chitotriosidase activity: a pathophysiological link between inflammation and impaired insulin sensitivity?

Polycystic ovary syndrome (PCOS) is characterized by insulin resistance. Chronic low grade inflammation has been reported to participate in the pathogenesis of insulin resistance. Chitotriosidase (ChT), a protein secreted by activated macrophages, has been shown to be involved in chronic inflammatory responses. In the present study, serum chitotriosidase activity and its relationship with insulin resistance were determined in patients with PCOS.34 patients with PCOS and 44 age and body mass index (BMI) matched healthy controls were enrolled in the study. ChT activity was measured by the fluorescence method. High sensitivity C reactive protein (hs-CRP) and adiponectin levels were determined by enzyme immunoassay (EIA). Insulin resistance was calculated by the homeostasis model assessment of insulin resistance (HOMA-IR) formula.Plasma ChT activity, hs-CRP level and HOMA-IR score were significantly higher (p=0.024, p=0.002, p=0.001, respectively) while plasma adiponectin concentration was significantly lower (p=0.018) in women with PCOS compared to healthy controls. Blood ChT activity correlated positively with age, waist-to-hip ratio (WHR), BMI, hs-CRP, HOMA-IR and negatively with blood adiponectin level. After adjustment for age and BMI, ChT activity, total testosterone level and WHR remained as the independent predictors of HOMA-IR score in logistic regression analysis.ChT activity is increased in patients with PCOS in concordance with insulin resistance. These findings may reflect the pronounced risk for metabolic syndrome and atherosclerotic diseases in this particular patient group.

Modified central aortopulmonary shunt with end-to-end anastomosis of the shunt to the pulmonary trunk: Early results of a novel shunt procedure for first-stage palliation of infants with pulmonary atresia and hypoplastic pulmonary arteries.

OBJECTIVE: The aim was to investigate a novel palliative shunt performed between the ascending aorta and the main pulmonary artery in patients with pulmonary atresia. PATIENTS AND METHODS: Thirteen patients with intracardiac defects [tetralogy of Fallot (seven patients); tetralogy of Fallot and major aortopulmonary collateral arteries (one patient); ventricular septal defect and major aortopulmonary collateral arteries (two patients); tricuspid atresia (three patients)] and pulmonary atresia underwent shunt operation. Patient selection was made based on preoperative echocardiography and perioperative findings. Eight of the patients were female and five were male. Ages and weight ranged between 1-235 days and 2,950-7,900 g, respectively. Preoperative room air oxygen saturation ranged between 68-83 %. RESULTS: Operations were performed through a median sternotomy. The main pulmonary artery was transected from the right ventricular outflow tract and using a 3-3.5 mm diameter graft, a modified central aortopulmonary shunt was created (graft anastomosis was end-to-end to the pulmonary artery and side-to-side to the aorta). Postoperative oxygen saturation increased 5-10% and diastolic blood pressure decreased by 3-6 mmHg. One hospital mortality occurred, due to sepsis, and two late deaths, one due to pneumonia and one sudden death, occurred in the follow-up period. Patients were followed up for 3-16 months after the operations. During the follow-up period four patients received corrective operations, one unifocalization and three total corrections. CONCLUSION: Modified central aortopulmonary shunt with end-to-end anastomosis of the shunt to the pulmonary trunk is a novel palliative shunt operation. Our early results with this technique indicate rapid palliation and early achievement of bilateral homogenous adequate pulmonary artery size with a low incidence of overflow to pulmonary circulation and minimal arterial distortion.

Late development of dissecting aneurysm following balloon angioplasty of native aortic coarctation.

Acute aortic dissection during balloon angioplasty for coarctation of the aorta or aneurysm formation during follow-up are well-known complications of this procedure. Dissecting aneurysm development during long-term follow-up after balloon angioplasty of a native coarctation has not been previously reported. We report a case in which a huge dissecting aneurysm developed 3 years after the native coarctation angioplasty procedure. The aneurysm required surgical repair.

Development of Kasabach-Merritt syndrome following needle aspiration of a hemangioma.

A case of Kasabach-Merritt syndrome that developed following needle aspiration in an infant with hemangioma is presented. Enlargement of the tumor leading to severe respiratory distress accompanied by hemorrhages occurred within six to eight hours after this simple intervention. The symptoms continued despite repeated thrombocyte transfusions and prednisolone therapy. Radiotherapy and local intraarterial corticosteroid therapy were attempted and led to some improvement. It took approximately three months for the platelet count and one year for the clinical state to revert to normal. This case illustrates that minor trauma may lead to life-threatening symptoms in a young infant with congenital hemangioma.

Intra-articular metastatic melanoma of the right knee.

Melanoma can metastasize to almost every organ and tissue. Although bone metastases have been reported frequently, the authors are aware of only a single report of intra-articular synovial metastasis. A case of metastatic melanoma, mimicking degenerative medial meniscal tear of the right knee, is presented. Further examination revealed asymptomatic metastases in the liver, subcutaneous tissue, and left trochanter minor. Arthroscopic examination revealed widespread synovial metastasis and a palliative arthroscopic synovectomy was performed.
