Abstract
OBJECTIVE Tp-e interval and Tp-e/QTc are among the new-generation indicators used for predicting cardiac arrhythmia and ventricular repolarization. In this study, we aimed to evaluate Tp-e and Tp-e/QTc ratios in patients with overt hypothyroidism and subclinical hypothyroid patients. PATIENTS AND METHODS In this study, a total of 105 patients were included with 35 overt hypothyroidism, 35 subclinical hypothyroidism, and 35 healthy euthyroid patients. The anthropometric measurements, laboratory results, and electrocardiographic data of the patients were measured. The groups were compared in terms of Tp-e interval, Tp-e/QT and Tp-e QT/c ratios. RESULTS When the Tp-e interval and Tp-e/QTc values of the patients were compared, a significant difference was found (p<0.001). A positive correlation was found between thyroid stimulating hormone (TSH) with Tp-e interval and Tp-e/QT ratio. CONCLUSIONS Tp-e interval and Tp-e/QTc duration increased in overt hypothyroidism and subclinical hypothyroidism patients compared to euthyroid patients. We believe that regular use of levothyroxine therapy in overt hypothyroidism patients will decrease cardiac mortality. Cardiac risk factors should be considered to decide on levothyroxine therapy for subclinical hypothyroidism patients.

Abstract
Zoonoses are frequently associated with wild animals. Research on reptiles either living in their natural habitat or kept as pet animals has shown that these animals frequently serve as the asymptomatic hosts of bacterial zoonotic agents, including Salmonella spp. and Escherichia coli. Studies have shown the potential of reptiles to transmit these pathogens to humans and other animals. Epidemiological research on the herpetofauna of various regions has demonstrated the high potential of reptiles as a reservoir of Salmonella spp. In the present study, Salmonella spp. were not isolated or identified from the snake-eyed lizard. Out of 150 cloacal swab samples of snake-eyed lizard 25 (16.7%) E. coli were isolated and out of these 4 (2.7%) were identified to be E. coli O157:H7 by PCR. The results suggest that Ophisops elegans could be involved in the transmission of E. coli, rather than Salmonella spp. This study demonstrates for the first time that the snake-eyed lizard acts as a cloacal carrier of E. coli O157:H7 and presents data that may aid in preventing the transmission of this strain to humans.

Abstract
PURPOSE To evaluate the effects of metformin alone and combined treatment with metformin and an SGLT2 inhibitor on retinal microvascular morphology using optical coherence tomography angiography (OCTA) in isolated type 2 diabetes mellitus (DM) patients with HbA1c above the expected target (>7%). METHODS Fifty patients with isolated DM, 7%<HbA1c<8%, without diabetic retinopathy (DR) using 500mg metformin ×2 for glycemic control were included in the study. OCTA and BMI measurements were obtained at the first evaluation. Treatment was changed to metformin 1000mg ×2. Patients who did not develop side effects due to the metformin were defined as the metformin-tolerant group (group-1). Patients who developed side effects were defined as the metformin-intolerant group (group-2), and their treatment was changed to metformin 500mg ×2 and empagliflozin 10mg. The second evaluation was performed three months after the last treatment change. RESULTS HbA1c was lower on the second evaluation in both groups (P<0.001, in both). On the second evaluation in group-1, a decrease was found in superficial perifoveal and deep parafoveal macular vascular plexus densities (P: 0.040 and P: 0.020, respectively). No statistically significant difference was observed in group-2. CONCLUSION SGLT2 inhibitors may contribute to preventing the development of preclinical DR. In patients with metformin intolerance, adding SGLT2 inhibitors may be a reasonable choice to protect the retina.

Abstract
We investigated the antioxidant effects of vitamin E on a glucocorticoid (GC) induced model of cataracts in chick embryos. We used 70 fertilized eggs divided into seven groups as follows: phosphate-buffered saline (PBS) group, olive oil treatment (OO) group, hydrocortisone treatment (HC) group, olive oil and hydrocortisone treatment (OO + HC) group, 50 mg/kg vitamin E and hydrocortisone treatment (HC + VE (50)) group, 25 mg/kg vitamin E and hydrocortisone treatment (HC + VE (25)) group and 15 mg/kg vitamin E and hydrocortisone treatment (HC + VE (15)) group. On day 17, chick embryos were removed from the eggs and lens and liver tissues were excised. Cataract formation was evaluated and total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA) and glutathione peroxidase (GPx) were measured in lens and liver tissues; MDA was measured only in liver. The lenses in the HC + VE (50) group exhibited significantly higher levels of GPx and TAS, and lower levels of TOS than for HC and OO + HC groups. The livers of the HC + VE (50) group exhibited significantly higher levels of GPx and lower levels of MDA than for the HC and OO + HC groups. The HC + VE (50) group lenses were evaluated as grade 1, because the nuclei were completely free of cataracts, likely due to the antioxidative effect of high dose VE. VE is an effective antioxidant agent that exhibits a dose-response effect, for ameliorating the negative effects of GCs.

Abstract
Background Thyroid nodules are a common pathology worldwide. Fine needle aspiration biopsy (FNAB) is an important diagnostic method for the investigation of malignancy in thyroid nodules. However, according to the Bethesda System used to classify the results, patients with atypia of undetermined significance/follicular lesion of undetermined significance (AUS / FLUS) may not be classified as benign or malignant. Therefore, it may be necessary to determine some clinical risk factors to apply the best treatment in these patients. Aim To determine the factors that increase the risk of malignancy in this patient group. Methods A retrospective study including 138 patients with an FNAB categorized as AUS/FLUS and operated between June 2015-September 2018. Demographical, Laboratory (TSH) and Ultrasound variables (number, size and characteristics of nodules) of the patients were compared among postoperative histopathological results. Results Hypo-echoic structure, microcalcification and irregular margin of the nodules were detected to be associated with malignancy in patients with FNAB results of AUS/FLUS (p <0.001). Conclusion We suggest that surgical treatment should be considered if the patients have nodules with the hypo-echoic structure, microcalcification and irregular margin with an FNAB histopathological result of AUS / FLUS.

Abstract
PURPOSE Gossypol, a naturally occurring compound in cottonseeds, has anticancer effects against several tumor cell lines. It has been extensively studied in clinical trials and is well tolerated with a favorable safety profile. AT-101, a derivative of R (-)-gossypol, binds to Bcl-2 family proteins and induces apoptosis in vitro. Although transsphenoidal surgical excision of the pituitary corticotroph adenoma is the gold standard of care, it is not successful all the time. Medical therapy for Cushing's disease still remains a challenge for the clinicians. We aimed to investigate the cytotoxic and apoptotic effects of AT-101 in mouse pituitary corticotroph tumor AtT20 cells. METHODS Cytotoxic effect of AT-101 was assessed by XTT cell viability assay. Apoptosis was shown by measuring DNA fragmentation and Caspase-3/7 activity. Changes in mRNA expressions of apoptosis-related genes were investigated by qPCR array after treatment with AT-101. ACTH was measured by ACTH-EIA Kit. RESULTS AT-101 induced cytotoxicity and apoptosis in AtT20 cells. mRNA levels of pro-apoptotic genes such as TNFR-SF-10B, Bid, PYCARD, Caspase-8, Caspase-3, and Caspase-7 were induced by 2.0-, 1.5-, 1.7-, 1.5-, 1.6-, and 2-fold, respectively, in AtT20 cells by AT-101 treatment. Moreover, some of the anti-apoptotic genes such as BCL2L10, NAIP1, and PAK-7 were reduced by 2.1-, 2.3-, 4.0-fold, respectively, in AtT20 cells. AT-101 also decreased ACTH secretion significantly. CONCLUSION AT-101 induces apoptosis in mouse pituitary corticotroph tumor cells.

Abstract
OBJECTIVES The aim of this study was to investigate the elastic properties of the aorta and the myocardial performance index of the left ventricle (LV) in patients with lichen planus (LP). SUBJECTS AND METHODS A total of 54 patients with LP and 50 controls were enrolled in the study. The 2 groups were well-matched regarding age, gender, body mass index, any smoking history, diabetes mellitus and systolic and diastolic blood pressure (SBP and DBP). The echocardiographic examination was performed on the study subjects and the controls. Aortic elasticity parameters and the myocardial performance index of the LV were calculated. The Student t test, the x03C7;2 test and multiple linear regression were used for the statistical analysis. RESULTS Aortic strain (AS, 4.77 ± 1.81 vs. 8.95 ± 2.22; p < 0.001) and aortic distensibility (AD, 0.25 ± 0.009 vs. 0.42 ± 0.120; p < 0.001) were significantly lower, and aortic stiffness index β (ASIβ, 3.65 ± 1.03 vs. 2.70 ± 0.91; p < 0.001) was significantly higher in the LP group than in the controls. The myocardial performance index (Tei index) was significantly higher in the LP group than in the control group (p = 0.001). The duration of the LP was negatively correlated with AS (r = -0.364, p < 0.001) and AD (r = -0.279, p = 0.006), and positively correlated with the Tei index (r = 0.324, p = 0.001) and ASIβ (r = 0.364, p < 0.001). After adjustment for relevant confounders (age, male gender, smoking, SBP, DBP, diabetes mellitus and low- and high-density lipoprotein cholesterol), LP and its duration were still associated with AS, AD and ASIβ. CONCLUSION In this study, AS and AD were lower and ASIβ and myocardial performance index higher in LP patients than in controls.

Abstract
AIM Carotid revascularization is an established theurapeutic modality in preventing stroke and death among patients with severe carotid stenosis. Although carotid endarterectomy remains as the primary option, carotid stenting is accepted as an alternative for patients with high risk for carotid endarterectomy. Recently published reports have better results with proximal protection devices when compared with distal protection devices. These studies have revealed less microembolic signals and less periprocedural new ischemic lesions on diffusion weighted magnetic resonance imaging. Stent choice may be also important for these procedures as open cell stent design has advantage of better flexibility whereas closed cell systems have an advantage of better scaffolding. Hybrid stents which are composed of open cells in the proximal and distal part and closed cells in the middle may carry both advantages. The aim of this study is to demonstrate whether combination of proximal protection devices with hybrid stents can be a safe alternative for carotid stenting in terms of periprocedural and 30-day outcomes. METHODS Here we retrospectively evaluated 68 symptomatic carotid stenosis patients undergoing carotid stenting with hybrid stent (Cristallo Ideale®, Invatec s.r.l., Medtronic, Italy) and proximal protection device (MO.MA®, Invatec s.r.l., Medtronic, Italy). RESULTS Our results showed only 1 minor stroke in the periprocedural period and during the first 30-day after stenting, with no death or myocardial infarction. CONCLUSION Although our case number is not large, we propose that carotid stenting may be safer with utilization of proximal protection system and hybrid type carotid stents.

Abstract
BACKGROUND AND AIM Sarcoidosis is a multi-systemic granulomatous disease of unknown etiology. The present study has been designed to evaluate the importance of diastolic dysfunction with left atrial volume index (LAVi) and left ventricular mass index (LVMi) in determining subclinical cardiac involvement in subjects with stage I-II pulmonary sarcoidosis. METHODS A total of 54 patients under follow-up for sarcoidosis without cardiac involvement and 56 healthy subjects were included in the study. The echocardiographic assessment of the patients revealed no significant difference between the two groups regarding left ventricular end-systolic and end-diastolic diameters, ejection fraction (LVEF) and annular velocity determined by tissue Doppler evaluation. RESULTS The LVEF calculated was 61.8 ± 7.8 % in the sarcoidosis group versus 64.1 ± 2.7 % in the control group (p = 0.04). Left ventricular interventricular septum thickness, posterior wall thickness, and relative wall thickness were significantly higher in the sarcoidosis group compared to the control group (p < 0.001). The sarcoidosis group had higher LVM and LVMi values compared to the control group (145 ± 18.1 and 79 ± 14 g/m(2), 135 ± 27.7 and 74 ± 14.2 g/m(2); p = 0.020 and p = 0.021, respectively). Left atrial end-systolic volume and LAVi were higher in the sarcoidosis group (28.7 ± 18.5; 15.6 ± 10.2) compared to the control group (16.6 ± 10.9; 8.9 ± 5.5) with a statistically significant difference (p < 0.001). CONCLUSION The present study indicates diastolic dysfunction and increased LVMi despite normal systolic function in patients with early-stage sarcoidosis without cardiac involvement. Also, the diastolic parameters were normal without showing any significant difference compared to the control group while there was a statistically significant increase in LAVi. This finding suggests that LAVi may be the earliest marker of diastolic dysfunction in patients with early-stage sarcoidosis without cardiac involvement.

Abstract
Objectives: The aim of this single-center study was to assess the incidence and predictors of in-hospital access site complications related to transcatheter aortic valve implantation (TAVI) performed with new delivery systems in our hospital which has the largest case series in Turkey. Materials and method: We performed successful TAVI with the Edwards Sapien XT valve to 127 (46 male) patients via a transfemoral (121), trans-subclavian (5) and transapical (1) approach. Access site complications were defined according to the Valve Academic Research Consortium (VARC) end-point definitions. Results: Vascular complications occurred in 10.1% of patients. There was negative correlation between vascular complications and diameter of the common femoral artery (r = − 0.301, p=0.004), external iliac artery (r = − 0.327, p=0.004) and common iliac artery (r = − 0.324, p=0.004), but positive correlation between diabetes (r =0.240, p=0.008), sheath to femoral artery ratio (SFAR), sheath to external iliac artery ratio (SEIAR), procedure time, discharge time and the Society of Thoracic Surgeons (STS) score (respectively; r=0.339, 0.001, 0.527, 0.361, 0.289, p=0.003, 0.001, 0.001, 0.001, 0.002). The incidence of vascular complications was significantly higher in patients with diabetes and a high STS score. VARC bleeding complications occurred in 11.7 % of patients. The learning curve pointing out the importance of experience was significantly important in decreasing both bleeding and vascular complications. Conclusions: In this study, we demonstrated that major vascular complications related to TAVI decrease with the use of smaller delivery systems and experience and increase with high-risk scores (STS) and the presence of diabetes. In addition, VARC major vascular complications, observed mostly in patients with diabete mellitus (DM) and high STS scores, were associated with vascular diameters. These results further underline the importance of experience and a multidisciplinary team in patient selection and management for TAVI.

Abstract
AIM We aimed to investigate the incidence and clinical relevance of incidental parathyroidectomy (IPT) following thyroid surgery. METHODS A retrospective review of thyroid operations was performed between January 2013 and January 2014. Pathology and operative reports were analyzed to identify the specimens which included parathyroid tissue. Information related to diagnosis, operative details and postoperative complications were collected. Calcium levels of ≤8 mg/dL was defined as biochemical hypocalcemia and those presenting with classic findings of acute hypocalcemia, were classified as clinical hypocalcemia. RESULTS Two hundred and forty-five thyroid procedures were performed during study period. IPT was found in 34 (13.8%) cases: 25 were benign and 9 were malignant. Parathyroid tissue was found intrathyroidal in 6 patients (17.6%); lobar locations were right lobe in 19 (55.8%) and left lobe in 13 (38.2%) and isthmus in 2 cases (5.8%). The frequency of biochemical and clinical hypocalcemia were 50% (N.=17) and 8.8% (N.=3), respectively. Neither surgical type (lobectomy or thyroidectomy) nor malignancy (benign or malign) was not found associated with biochemical hypocalcemia. In those with biochemical hypocalcemia, left location of both dominant nodule and extracted parathyroid gland were significantly higher (P=0.01 and 0.04, respectively). CONCLUSION Incidental parathyroidectomy which is not uncommon (13.8%) after thyroidectomy is not associated with postoperative biochemical hypocalcemia. Neither the type of surgical procedure (lobectomy or thyroidectomy) nor the pathology but adjacent dominant nodule location may increase the risk of IPT.

Abstract
BACKGROUND The treatment of castrate-resistant prostate cancer (CRPC) still remains as an important challenge of daily oncology practice. Docetaxel significantly prolongs overall survival in men with CRPC. Thymoquinone (TQ), one of the flavonoid compounds isolated from Nigealla sativa, has been shown to possess cytotoxic activity against a variety of cancer cell lines. MATERIALS AND METHODS The aim of the study was to investigate the possible synergistic cytotoxic/apoptotic effects of a novel combination, docetaxel and TQ in DU-145 hormone- and drug-refractory prostate cancer cells and their effects on PI3K and ERK signaling pathways. RESULTS We observed that the combination of docetaxel and TQ resulted in a significant synergistic cytotoxicy and apoptosis as compared to any single agent alone, in a dose-dependent manner. It was found that viability of the combination treated cells was not significantly changed in the presence of LY294002 as compared to inhibitor treated cells. However, in the presence of FR180204, viability of combination treated cells was significantly decreased as compared to inhibitor treated cells. In conclusion, cytotoxic effect of the docetaxel and TQ combination is correlated with the block of the PI3K/Akt signaling pathway in DU-145 cells. CONCLUSION Therefore, this combination strategy may be an alternative approach for the challenging era of daily oncologic practice. Also, the combination of docetaxel and TQ might allow a reduction in docetaxel doses and diminish adverse effects of docetaxel while maintaining the therapeutic effect in patients with CRPC.

Abstract
BACKGROUND AND OBJECTIVE Hyperglycemia on admission is associated with increased mortality and morbidity in acute coronary syndrome (ACS) irrespective of presence of diabetes mellitus. To the best of our knowledge, no evidence on the relationship between stress hyperglycemia (SH) and the extent of coronary artery disease is found in the literature. Our objective in this study is to assess the relationship of SH with the prognosis of acute coronary syndrome, extent of coronary artery disease (CAD), development of arrhythmia, and major adverse cardiac events. METHOD 89 patients who were hospitalized in the coronary intensive care unit with diagnosis of ACS between January 2010 and June 2010 were enrolled in the study. The patients were separated into 2 groups as having stress hypergly-cemia or not, according to their blood glucose levels on admission. TIMI and GRACE risk scores were obtained and GENSINI scoring was performed to assess CAD extent for all the patients. Major adverse cardiac events (MACE) (death, MI, re-revascularization, stroke) were recorded for all patients while in the hospital and at 1st and 6th months. RESULTS In our study, MACE, GENSINI scores at 6 months and development of in-hospital arrhythmia rates were statistically significantly higher and left ventricular ejection fractions were statistically significantly lower in the group with SH. The association of TIMI, GRACE, GENSINI, New York Heart Association (NYHA) and Killip classifications with blood glucose, fasting blood glucose and HbA1c on admission was confirmed. CONCLUSION Prognostic course happens to be worse and CAD is more extensive in patients with SH. In addition, blood glucose values may have to be estimated lower compared to the samples in the literature, in order to diagnose SH.

Abstract
INTRODUCTION This study examined the effect of coronary artery revascularization on left ventricular function and the results of strain imaging for the detection of ischemia before and after coronary artery bypass graft (CABG) surgery. MATERIAL AND METHODS Sixty-eight patients with a history of coronary artery disease (CAD) were included, prospectively. Conventional echocardiography and color tissue Doppler-derived strain-strain rate echocardiographic imaging were performed 24 hours before and 3 months after CABG surgery. RESULTS While strain rate values of the basal septum, middle segment of the lateral wall, middle segment of the inferior wall, and middle and basal segments of the anterior wall were significantly increased, other segments did not change after the operation. The mean systolic strain rate value was significantly increased after the operation. Left ventricle strain values in the middle segment of the septum, middle and basal segments of the inferior wall, and middle and basal segments of the anterior wall were significantly increased after the operation. No significant difference was noted in the basal septum or the middle and basal segments of the lateral wall after the operation. The mean systolic strain value was significantly increased after the operation. CONCLUSION The results of this study suggest that strain and strain rate echocardiography can provide an accurate evaluation of regional contractile function after CABG, even in the segments that are apparently normal.

Abstract
In this case presentation, the transcatheter aortic valve implantation (TAVI) intervention successfully performed on a 76-year-old male patient with severe degenerative aortic stenosis and diagnosed with myelodysplastic syndrome (MDS) is discussed. This case presentation represents the first case on the treatment of severe aortic stenosis on a patient with myelodysplastic syndrome through the use of the TAVI method and may form an alternative to surgery in patients with severe aortic stenosis who have a known haematological disease. For a successful procedure, the patient must be evaluated in cooperation with the haematology clinic and all necessary precautions regarding bleeding and infection complications of the patient must be taken prior to the procedure.

Abstract
OBJECTIVE Prostate-specific antigen (PSA) is a well-known prostate cancer marker. Recent studies have shown that serum PSA levels can fluctuate in response to cardiovascular stress. In this study we aimed to determine if serum PSA levels correlate with the presence and stages of coronary artery disease (CAD) and whether PSA can be used as a marker for the diagnosis and severity of CAD. PATIENTS AND METHODS This was a retrospective chart review of male patients who underwent coronary angiography for suspected CAD. A total of 100 patients with angiographic data and baseline serum PSA measurements were included. Patients with previous history of coronary angiography, stent implantation, benign prostate hypertrophy, known prostate cancer or prostatitis were excluded. RESULTS The mean age was 57±10 years. Coronary angiography results were normal in 13%, non-obstructive CAD (non-critical plaque formation) in 16%, one-vessel disease in 21%, two-vessel disease in 30% and multi-vessel disease in 20%. Mean values of total and free serum PSA were 1.4±1.3 ng/mL and 0.4±0.4 ng/mL, respectively. Although there was an increasing trend of PSA with more advanced stages of CAD, no significant relationship was established (p > 0.05). Patients with hypertension had significantly elevated total and free serum PSA compared to normotensives. There is no comparison of PSA levels between patients with CAD and without CAD. CONCLUSIONS Our study suggests that there is no direct relationship between increasing levels of PSA and stage of CAD. Thus, PSA level does not appear to be a suitable marker for diagnosis or severity of CAD.

Abstract
BACKGROUND AND AIM Ischemic cerebrovascular events are the most common reason for patients to be bedridden and the third most common reason for death. Many studies in recent years have demonstrated that carotid artery stenting (CAS) may be an alternative to carotid endarterectomy (CEA). In this study, we aimed to report early outcomes of patients who were treated with CAS in our clinic and discuss practicability, advantages and safety of CAS. METHODS AND FINDINGS Eighty patients who underwent CAS between December 2009 and May 2011 were eligible. The mean age was 65 years (range, 49 - 89 years). Of the study group, 73.75% were males and 26.25% were female. The percentage of asymptomatic patients was 11.7%, and the remaining patients were symptomatic. A distal embolic protection device (Angioguard®) was used in 22% of the patients whereas, in the other patients (78%), a proximal blockage system (Mo.MA®) was used. Self-expandable hybrid stents were implanted in all patients and post-dilatation was performed after implantation. None of the patients suffered from stroke, myocardial infarction or death due to CAS during their hospital stay. The mean follow-up period was 10 months (range 2 - 18 months) after discharge. None of the patients had died or had a stroke, a transient ischemic attack (TIA), or a myocardial infarction during the follow-up period. Re-stenosis was not observed in the follow-up carotid Doppler ultrasonography; flow rates were within normal limits. CONCLUSION No major complication was observed during the early follow-up period in patients who underwent CAS in our clinic. Only 2 (2.5%) patients showed transient numbness and weakness and these did not lead to morbidity. In the management guide of extracranial carotid and vertebral artery diseases, CAS, in the light of recent studies, is recommended as an alternative to CEA in recommendations for revascularization. One of the important issues emphasized in this guide is the experience of centers. Very low complication rates after CAS suggested that, with suitable patient selection and an experienced team, similar results may be obtained.

Abstract
PURPOSE We aimed at evaluating the effects of posterior continuous curvilinear capsulorhexis (PCCC) on contrast sensitivity. MATERIALS AND METHODS In this prospective, randomized, bilateral clinical study, 40 eyes of 20 patients who underwent bilateral cataract surgery were included. The phacoemulsification machine, viscoelastic substances, surgical tools, and intraocular lenses (IOLs) were the same for both eyes. The only difference was that we conducted the PCCC procedure before IOL implantation to one of the eyes of the patients. The selection of the eye that underwent the PCCC procedure was decided randomly. RESULTS The mean photopic contrast sensitivity values at spatial frequencies of 1.5, 3, 6, 12, and 18 cpd (cycles per degree) were 41.55, 59.90, 61.25, 32.35, and 9.75, respectively, and for the control group these values were 39.05, 56.60, 57.95, 29.80, and 8.75, respectively. The mean mesopic contrast sensitivity values at special frequencies of 1.5, 3, 6, 12, and 18 cpd were 41.20, 54.75, 55.55, 31.70, and 9.00, respectively, and for the control group these values were 38.35, 51.70, 52.15, 30.05, and 8.00, respectively. The mean contrast sensitivity values of the eyes that underwent the PCCC procedure were slightly better than the fellow eyes at all spatial frequencies, but the difference was statistically insignificant (P>0.05). CONCLUSIONS In early post-operative period, the PCCC procedure exerts some positive effects on contrast sensitivity although these effects are statistically insignificant.

Abstract
OBJECTIVE To verify whether tissue Doppler imaging (TDI) could contribute to a better understanding of the natural history of cardiomyopathy in active Cushing's disease (CD), through its enhanced sensitivity to diastolic dysfunction, and identifying preliminary regional signs of systolic dysfunction before the appearance of clinical symptoms of cardiac pathologies. METHODS Eleven women with newly diagnosed CD and 32 control cases, purposely matched for gender, age, body mass index and co-incidental diseases were enrolled in this study. Echocardiographic examinations were assessed by conventional echocardiography and tissue Doppler imaging. The peak systolic velocity (S'm), early diastolic myocardial peak velocity (E'm), late diastolic myocardial peak velocity (A'm), isovolumic acceleration (IVA), myocardial pre-contraction time (PCT'm), myocardial contraction time (CT'm) and myocardial relaxation time (RT'm) were measured at septal and lateral mitral anulus. RESULTS In TDI, E'm and, E'm/A'm ratio were significantly lower, and PCT'm/CT'm ratio was higher, S'm, A'm, peak early diastole/E'm ratio, PCT'm, and isovolumetric myocardial relaxation time values were similar at lateral and septal anulus in patients with CD than controls (p>0.05). Lateral and septal anulus IVA were significantly lower in patients with CD than the control group (p<0.05). Correlation analysis showed that IVA time at lateral anulus correlated positively with S'm at lateral anulus (r=0.58; p=0.002) and IVA time at septal anulus correlated positively with S'm at septal anulus (r=0.51; p=0.008). CONCLUSION Our study confirms that patients with CD have impaired diastolic function. More importantly, we also demonstrated an impairment of myocardial systolic function in patients with CD by TDI. We recommend using TDI in addition to conventional echocardiography parameters for the cardiovascular risk assessment of patients with Cushing' syndrome.

Abstract
OBJECTIVES Adrenomedullin (ADM) production and secretion have been reported in endothelial cells. The present study was designed to assess whether coronary angiography (CA) and percutaneous transluminal coronary angioplasty (PTCA) affect plasma ADM levels. DESIGN AND METHODS We measured plasma concentrations of ADM using a specific radioimmunoassay method in patients undergoing coronary angiography or PTCA before and after a 5-minute procedure. Patients were divided into three groups; group I: normal coronary angiography group (11 males, 10 females; mean age 55.90 +/- 11.03 yrs), group II: coronary artery disease (CAD), only coronary angiography performed (14 males, 8 females; mean age 60.95 +/- 9.80 yrs), group III: PTCA performed in patients with CAD (35 males, 11 females; mean age 55.89 +/- 10.41 yrs). RESULTS The plasma ADM levels and left ventricular end diastolic pressures measured before the procedure were similar in the three groups (p > 0.05). Plasma ADM levels were 13.98 +/- 2.26, 15.59 +/- 6.70, 17.15 +/- 8.47 pg/ml respectively. ADM levels measured after CA showed no significant difference in group I (13.75 +/- 1.75 pg/ml) or group II (16.50 +/- 7.18 pg/ml) (p > 0.05). A marked elevation was observed in group III with ADM levels of 27.31 +/- 12.27 pg/ml after PTCA (p < 0.01). The ADM levels observed in group III after PTCA were significantly higher than those of group I and group II after coronary angiography (p < 0.001). CONCLUSION The results of our study show an increase of ADM after PTCA but not after coronary angiography in patients with or without CAD. We think that the increase of ADM levels may be due to cardiac secretion from endothelial and smooth muscle cells following balloon injury.

Abstract
We report the first case of an acquired form of generalized cutis laxa which has positive serology and a positive polymerase chain reaction (PCR) result for lyme borreliosis. A 44-year-old man complained of excessively loose skin for four years and had no family history of any skin disease. Dermatological examination showed lax and wrinkled skin all over the body (especially on the cheeks and the intertriginous areas). Positive serology for lyme borreliosis and the presence of Borrelia burgdorferi DNA which was demonstrated by nested PCR in this acquired form of cutis laxa is interesting since it has not been reported in literature previously.

Abstract
Radiation therapy for subfoveal neovascularization has not yet proved its efficiency, but, to our knowledge, no exudative complication of this treatment has been reported. We describe a late side effect observed in 16 eyes after a mean follow up of 33 months, characterized by major extension and exudation of the choroidal new vessels. In several cases, development of elongated, club like new vessels was observed at the border of the neovascular membrane. At the end of the follow-up, 4 eyes had an exudative retinal detachment affecting half of the retina or more and visual acuity was < or = 1/50 in 94% of the cases (including a case with no light perception and 2 cases with only light perception).

Abstract
Perifoveolar photocoagulation is advised for subfoveal choroidal neovascularization responding to the MPS eligibility criteria. Recently, radiation therapy has been proposed but has not yet proved its efficacy. We compared these two treatments. We retrospectively reviewed 27 patients with age related macular degeneration and subfoveal choroidal neovascularization in both eyes. The first eye was treated with perifoveolar photocoagulation and the second eye with radiotherapy. In case of simultaneous diagnosis, radiotherapy was performed in the eye with the best visual acuity. Although the follow up is two times longer and the initial visual acuity is lower in the group of the photocoagulated eyes, both groups have similar results at the end of their respective follow up. However, in the eyes treated with radiotherapy the lesions are still active and edematous while in the eyes treated with perifoveolar photocoagulation, the lesions are stable and dry. The percentage of patients who subjectively prefer the photocoagulated eye has increased progressively from 0% to 71.5% along the 20 months of follow-up post radiotherapy. The perifoveolar photocoagulation of the subfoveal choroidal neovascularization seems, at median term, to give better objective and subjective results than the radiation therapy.
