Trichotillomania: A perspective from bibliometric analysis.

Aim: Trichotillomania, an obsessive-compulsive-related disorder, is defined by the recurrent act of pulling out one's own hair from different areas of the body. Despite the considerable body of research dedicated to the subject of trichotillomania, the overarching trends that unify these studies remain obscure. The purpose of the present bibliometric analysis was to ascertain these trends.Method: To achieve this objective, we conducted a thorough search of publications in the Web of Science database and subsequently evaluated the acquired data using VOSviewer software.Results: The most cited article on trichotillomania was written by Simonoff et al. The most prolific writer on trichotillomania is Grant JE. The most publications on the subject of trichotillomania were published in the "Journal of Obsessive Compulsive and Related Disorders" and the most frequently repeated keyword is trichotillomania. Trichotillomania studies have focused on treatment, clinical features, and other accompanying psychiatric conditions.Conclusion: Potential areas of research could include treatment methods in addition to the psychiatric and physical comorbidities of trichotillomania, and efforts to enhance international collaborations in this domain should be intensified.

Case report-right atrial mass: a very rare presentation of endometrial cancer metastasis.

Background: We report a case of a 47-year-old woman with right atrial metastasis of endometrioid adenocarcinoma, which is an uncommon clinical presentation for patients with endometrial cancer (EC). The principal aim of this case is to demonstrate the possibility of distant metastasis, something rarely encountered among this group of patients. Case summary: Our patient, diagnosed with EC and receiving chemotherapy and radiotherapy after surgery, was found to have enhanced 18-fluorodeoxyglucose uptake inside the right atrium on the repeat positron emission tomography-computed tomography scan at the ninth month after initial diagnosis. Following trans-oesophageal echocardiography, cardiac magnetic resonance imaging showed a hyper-vascular mass with right atrial lateral wall involvement likely to be malignant in nature. A right atrial tumour was successfully removed by cardiovascular surgeons, and a pericardial patch was placed at the site of the excised atrium. The pathological examination showed EC metastasis. Following surgery, systemic treatment was planned for recurrent EC. The patient had an uneventful recovery after the surgery. Discussion: Endometrial cancer is the most common gynaecologic malignancy and the fourth most common cancer in women. The lymphatic pathway is the main metastatic behaviour of EC; however, haematogenous metastases are not uncommon, especially in patients with higher stages of the disease. Our patient did not show any signs and symptoms of cardiac involvement. Nevertheless, clinicians should be alert for symptoms of cardiac involvement like new-onset murmur, embolism, or dyspnoea. Having known the behavioural pattern of the primary tumour, timely utilization of diagnostic imaging methods in accordance with clinical suspicions in patients with rapidly growing tumours can be lifesaving.

Short- and long-term outcomes of percutaneous coronary interventions of high-risk vs. low-risk lesions performed at a hospital without an on-site cardiac surgery unit.

Aim    Widespread utilization of technology has led to the construction of a growing number of facilities with coronary angiography units and percutaneous coronary intervention (PCI) capability. Some of these centers do not have cardiovascular surgery (CVS) on site. Studies regarding the efficacy and safety of PCIs performed at these hospitals have been conducted. However, to date, high-risk procedures in this context have not been evaluated. The present study compares the outcomes of PCI procedures performed on high- and low-risk lesions groups in a center without CVS back-up.Material and methods    A total of 999 patients treated with PCI with diagnoses other than ST elevation myocardial infarction were included in this study. Patients with SYNTAX scores 22 or higher, bifurcation lesions, chronic total occlusions, left main coronary artery lesions and saphenous graft lesions were classified as a high-risk group. In contrast, patients with SYNTAX scores lower than 22 were included in the low-risk group. Coronary lesions were classified as Type-A, B, and C. The 30­day major adverse cardiac events (MACE) and 1­year target vessel revascularization (TVR) rates were compared.Results    There was no significant difference between the groups in terms of the rates of MACE (2 (0.9 %) vs 5 (0.6 %); p=0.64) and TVR (9 (4.2 %) vs 25 (3.2 %); p=0.52). Analysis regarding the lesion type also revealed no significant difference between the MACE and TVR rates (p=0.56 and p=0.43, respectively).Conclusions    The findings in this study demonstrated that, similar to low-risk procedures, complex and high-risk coronary interventions can safely and effectively be conducted in hospitals without a CVS unit.

Apical longitudinal strain can help predict the development of left ventricular thrombus after anterior myocardial infarction

Abstract Background: Left ventricular (LV) thrombus formation is a common complication of anterior myocardial infarction (ANT-MI). The aim of this study was to investigate the relationship between apical longitudinal strain (ALS) and LV apical thrombus after ANT-MI. Methods: The cross-sectional study included a total of 235 patients who were followed up after primary percutaneous coronary intervention performed for ANT-MI and had a reduced LV ejection fraction (LVEF) (≤40%). Of these patients, 24 were excluded from the study, and the remaining 211 patients were included in the analysis. Patients were divided into two groups based on the presence (n = 42) or absence (n = 169) of LV thrombus detected by echocardiography. ALS was measured using speckle-tracking echocardiography. Results: Thrombus was detected in 42 of 211 patients. There was no significant difference between the groups regarding age or gender. Apical strain (AS), global longitudinal strain (GLS), apical wall thickness (AWT), and EF were significantly lower in patients with LV apical thrombus when compared to those without LV apical thrombus (AS, –5.00 ± 2.30% vs. −8.54 ± 2.48%, p < 0.001; GLS, −10.6 ± 3.54% vs. −12.1 ± 2.84%, p = 0.013; AWT, 4.71 ± 1.11 vs. 6.33 ± 1.78 mm, p < 0.001; EF, 31.40 ± 4.10% vs. 37.75 ± 3.17%, p < 0.001). On univariate and multivariate analyses, aneurysm (AA), AS, and AWT were found to be independent predictors of LV apical thrombus (AA, odds ratio [OR] 4.649, p = 0.010; AS, OR 1.749, p < 0.001; AWT, OR 0.729, p = 0.042). Conclusion: ALS is highly sensitive and specific for predicting LV thrombus after ANT-MI. An early and accurate evaluation of LV thrombus may prevent embolic complications, particularly cerebrovascular events.

Apical Longitudinal Strain Can Help Predict the Development of Left Ventricular Thrombus after Anterior Myocardial Infarction.

BACKGROUND: Left ventricular (LV) thrombus formation is a common complication of anterior myocardial infarction (ANT-MI). The aim of this study was to investigate the relationship between apical longitudinal strain (ALS) and LV apical thrombus after ANT-MI. METHODS: The cross-sectional study included a total of 235 patients who were followed up after primary percutaneous coronary intervention performed for ANT-MI and had a reduced LV ejection fraction (LVEF) (< -40%). Of these patients, 24 were excluded from the study, and the remaining 211 patients were included in the analysis. Patients were divided into two groups based on the presence (n = 42) or absence (n = 169) of LV thrombus detected by echocardiography. ALS was measured using speckle-tracking echocardiography. RESULTS: Thrombus was detected in 42 of 211 patients. There was no significant difference between the groups regarding age or gender.

On univariate and multivariate analyses, aneurysm (AA), AS, and AWT were found to be independent predictors of LV apical thrombus (AA, odds ratio [OR] 4.649, p = 0.010; AS, OR 1.749, p < 0.001; AWT, OR 0.729, p = 0.042). CONCLUSION: ALS is highly sensitive and specific for predicting LV thrombus after ANT-MI. An early and accurate evaluation of LV thrombus may prevent embolic complications, particularly cerebrovascular events.

Permanent His bundle pacing and atrioventricular node ablation in a case with drug-refractory atrial fibrillation.

Permanent His bundle pacing (HBP) activates the ventricles through the normal conduction system and has become a useful technique for patients with a high ventricular pacing rate. Presently described is a case of drug-refractory atrial fibrillation (AF) with a high ventricular rate that was treated with atrioventricular (AV) node ablation and permanent HBP. A 62-year-old woman with persistent AF and a drug-refractory high ventricular response was referred for exercise intolerance and palpitation. She had a history of failed catheter ablation attempts and amiodarone toxicity. Permanent HBP and AV node ablation was planned to achieve rate control with a stepwise approach. Initially, implantation of a permanent pacemaker was performed. The His lead and right ventricular back-up leads were implanted successfully, in the manner described previously. The His lead was connected to the atrial channel of the pacemaker battery and programmed to AAI pacing mode. The AV node was ablated successfully 3 weeks later without any threshold changes in the His lead. No His lead threshold changes were observed during or after AV node ablation and the patient was subsequently asymptomatic with twice daily apixaban 5 mg. Permanent HBP after AV node ablation can be a beneficial treatment option to prevent pacing-induced ventricular dyssynchrony and heart failure in patients who are not eligible for cardiac resynchronization therapy.

Multilayer longitudinal strain can help predict the development of no-reflow in patients with acute coronary syndrome without ST elevation.

No-reflow (NR) is one of the major complications of primary percutaneous coronary intervention (PCI) in patients with non-ST-segment elevation myocardial infarction (NSTEMI). We aim to assess the value of multilayer longitudinal strain parameter to predict NR in patients with NSTEMI and preserved ejection fraction. 230 consecutive patients who were admitted to the emergency department and diagnosed with NSTEMI were prospectively included in this study. Echocardiography was performed 1 h before angiography. Specific analysis for endocardial, mid-myocardial and epicardial layers were performed by two-dimensional (2D) speckle tracking echocardiography (STE) for multilayer longitudinal strain. NR was described as flow grade of ≤ TIMI 2 when mechanical occlusions like dissection, intimal tear, arterial spasm and thromboembolism during angiography were excluded. 49 of 168 patients admitted to the study had NR. No significant differences were observed between the groups regarding age and gender. Multilayer longitudinal strain imaging (endocard, midmyocard and epicard) revealed lower strain values particularly in endocardial layer in patients with NR (GLS-endocard: - 14.14 ± 1.39/- 17.41 ± 2.34, p < 0.001; GLS-midmyocard: - 14.81 ± 1.40/17.81 ± 2.22, p < 0.001; GLS-epicard: - 16.14 ± 1.38/18.22 ± 2.00, p < 0.001). GLS-endocard, GLS-midmyocard, GLS-epicard and ST depression were found to be statistically significant independents parameters respectively to predict NR phenomenon (GLS-endocard: OR: 2.193, p < 0.001; GLS-midmyocard: OR: 1.510, p: 0.016; GLS-epicard: OR: 1.372, p: 0.035; ST depression: OR: 3.694, p: 0.014). We revealed that left ventricular strain study with speckle tracking echocardiography predicts NR formation. This noninvasive method may be useful for detecting NR formation in patients with NSTEMI.

Ultraslow thrombolytic therapy: A novel strategy in the management of PROsthetic MEchanical valve Thrombosis and the prEdictors of outcomE: The Ultra-slow PROMETEE trial.

BACKGROUND: Low-dose (25mg), slow infusion (6hours) of tissue-type plasminogen activator (t-PA) with repetition as needed has been shown to provide effective and safer thrombolysis in patients with prosthetic valve thrombosis (PVT). Further prolonging the infusion time may be rational with regard to reducing complication rates without reducing success rates. We aimed to investigate the efficacy and safety of ultraslow (25hours) infusion of low-dose (25mg) alteplase (t-PA) for PVT. METHODS AND RESULTS: Transesophageal echocardiography-guided thrombolytic therapy (TT) was administered to 114 patients with PVT in 120 different episodes between 2009 and 2013 in a single center. Prosthetic valve thrombosis was obstructive in 77 (64.2%) and nonobstructive in 43 (35.8%) episodes. Ultraslow infusion (25hours) of low-dose (25mg) t-PA, as the TT regimen, was used in all patients admitted with PVT. The end points were thrombolytic success, mortality, and complication rates. The overall success rate of TT was 90% (95% CI 0.85-0.95). The univariate predictors of an unsuccessful result were higher New York Heart Association (NYHA) class, thrombus cross-sectional area, duration of suboptimal anticoagulation, lower baseline valve area, and presence of atrial fibrillation. The NYHA class was the only independent predictor of TT failure by multiple variable analysis. The overall complication rate was 6.7% (3.3% nonfatal major, 2.5% minor, and 0.8% death). The predictors of complications were presence of atrial fibrillation, higher NYHA class, and thrombus area. CONCLUSION: Ultraslow (25hours) infusion of low-dose (25mg) t-PA without bolus appears to be associated with quite low nonfatal complications and mortality for PVT patients without loss of effectiveness, except for those with NYHA class IV.

The role of GRACE score in the prediction of high-risk coronary anatomy in patients with non-ST elevation acute coronary syndrome.

BACKGROUND: In patients with non-ST elevation acute coronary syndrome (NSTE-ACS), identification of the patients with high-risk coronary anatomy (HRCA) who are most likely to require coronary artery bypass grafting (CABG) is crucial. The SYNTAX score (SXscore) is an angiographic grading tool designed to determine the complexity of coronary artery disease. It appears that CABG offers significantly better outcomes in patients with SXscore ≥ 33, which shows severe HRCA. AIM: We sought to assess the accuracy of the GRACE score in predicting HRCA in terms of SXscore in patients with NSTE-ACS. METHODS: Patients admitted to our coronary unit with a diagnosis of NSTE-ACS and undergoing coronary angiography during hospitalisation were recruited to this study. Patients were categorised into two groups based on SXscore: HRCA (SXscore ≥ 33) and low-risk coronary anatomy (LRCA, SXscore < 33). The cut-off level of GRACE score for HRCA was established by receiver operator characteristic (ROC) analysis. RESULTS: We studied 207 consecutive patients (mean age: 59 ± 11 years, 27.5% female). The GRACE score was 139 ± 34 in the HRCA group and 114 ± 33 in the LRCA group (p = 0.001). There was a significant positive correlation between SXscore and GRACE score (r = 0.338, p < 0.001). The area under ROC curve for GRACE score was 0.71 (95% CI 0.60-0.81, p = 0.001). A GRACE score of 123 was identified as the optimal cut-off to predict HRCA with a sensitivity of 71% and a specificity of 60%. In multivariate regression analysis, GRACE score ≥ 123 was the only variable that identified HRCA (OR 2.8, 95% CI 1.18-6.6, p = 0.019).Conclusions: Our study demonstrates that, in the setting of NSTE-ACS, patients with HRCA, who are most likely to require CABG, have higher GRACE scores at presentation. However, the ability of GRACE score to predict HRCA was modest.

Long-Term Impact of Different Immunosuppressive Drugs on QT and PR Intervals in Renal Transplant Patients.

BACKGROUND: Sudden cardiac deaths due to arrhythmias are thought to be an important cause of mortality in patients with renal transplants. Exposure to immunosuppressive drugs may lead to QT or PR interval abnormalities which may consequently cause arrhythmias. Our study investigated the long term impact of four different immunosuppressive drugs on PR and corrected QT intervals (QTc) in renal transplant patients METHODS: The study population consisted of 98 kidney transplant recipients. Study patients were receiving immunosuppressive management with tacrolimus, cyclosporine A, everolimus or azathioprine according to the local protocols. QTc and PR intervals obtained from the most recent post-transplant electrocardiograms were compared with the pre-transplant intervals dated before the transplantation procedure. RESULTS: Post-transplant QTc intervals had prolonged significantly in comparison to the pre-transplant QTc intervals in all groups. However, there were no significant differences between the immunosuppressive agents with regard to post-transplant QTc interval prolongation (p > 0.05). There were no significant differences between the groups with regard to the pre and post-transplant PR interval changes (p > 0.05). CONCLUSIONS: QT interval prolongation, a marker of risk for arrhythmias and sudden death, is highly prevalent among kidney transplant patients receiving different classes of immunosuppressive drugs.

Assessment of carotid body tumor and its association with tetralogy of fallot: effect of the chronic hypoxia.

This is a rare combined presentation of Tetralogy of Fallot and carotid body tumor (CBT). Hypotheses and further discussion provides data for the development of CBT as a response to chronic hypoxemia. This present study demonstrates and discusses such an occurrence.

Value of serum fibrinogen levels in the assessment of mechanical prosthetic valve thrombosis.

BACKGROUND AND AIM OF THE STUDY: The evaluation of prosthetic valve thrombosis (PVT) is crucial due to higher mortality and morbidity rates. The study aim was to assess the value of fibrinogen in the diagnosis of PVT, an important and a common cause of prosthetic valve failure. METHODS: Between December 2007 and April 2012, 154 patients with PVT and 116 control subjects with a normally functioning prosthesis were enrolled in the study. PVT was diagnosed using transesophageal echocardiography, and fibrinogen levels were measured at presentation. The patients and controls had similar demographic features. RESULTS: NYHA functional class, ineffective anticoagulation, presence of symptoms and moderate to severe left atrial spontaneous echo contrast (LASEC) were significantly different between the groups. The fibrinogen level was significantly higher in patients with PVT compared to controls (393.46 +/- 127.87 versus 276.93 +/- 69.22 mg/dl, p < 0.001). Ineffective anticoagulation, the presence of symptoms, a poor NYHA functional class, the presence of moderate to severe LASEC and elevated fibrinogen levels were independent predictors of PVT on multivariate regression analysis (p < 0.001, odds ratio (OR) 38.811, 95% confidence interval (CI): 13.319-113.091; p < 0.001, OR 6.745, CI: 2.777-16.386; p = 0.031, OR 3.557, CI: 1.126-11.239; p = 0.026, OR 3.203, CI: 1.146-8.955, and p < 0.001, OR 1.011, CI: 1.007-1.016 respectively). CONCLUSION: Besides known indicators of PVT, including ineffective anticoagulation, the presence of LASEC and decreased NYHA functional capacity, elevated fibrinogen levels may be a valuable marker for the assessment of PVT.

Comparison of different TEE-guided thrombolytic regimens for prosthetic valve thrombosis: the TROIA trial.

OBJECTIVES: The aim of this prospective study was to identify the most effective and safest regimen among different thrombolytic treatment strategies. BACKGROUND: The best treatment strategies for prosthetic valve thrombosis have been controversial. METHODS: Transesophageal echocardiography-guided thrombolytic treatment was administered to 182 consecutive patients with prosthetic valve thrombosis in 220 different episodes (156 women; mean age, 43.2 ± 13.06 years) between 1993 and 2009 at a single center. These regimens chronologically included rapid (Group I), slow (Group II) streptokinase, high-dose (100 mg) tissue plasminogen activator (t-PA) (Group III), a half-dose (50 mg) and slow infusion (6 h) of t-PA without bolus (Group IV), and a low dose (25 mg) and slow infusion (6 h) of t-PA without bolus (Group V). The endpoints were thrombolytic success, in-hospital mortality, and nonfatal complication rates. RESULTS: The overall success rate in the whole series was 83.2%; it did not differ significantly among Groups I through V (68.8%, 85.4%, 75%, 81.5%, and 85.5%, respectively; p = 0.46). The overall complication rate in the whole series was 18.6%. Although the overall complication rate was similar among Groups I through IV (37.5%, 24.4 %, 33.3%, and 29.6%, respectively; p > 0.05 for each comparison), it was significantly lower in Group V (10.5%, p < 0.05 for each). The combined rates of mortality and nonfatal major complications were also lower in Group V than in the other groups, with all differences significant except for comparison of Groups IV and V. By multivariate analysis, the predictors of combined mortality plus nonfatal major complications were any thrombolytic therapy regimen other than Group V (odds ratios for Groups I through IV: 8.2, 3.8, 8.1, and 4.1, respectively; p < 0.05 for each) and a history of stroke/transient ischemic attack (odds ratio: 3.5, p = 0.011). In addition, there was no mortality in Group V. CONCLUSIONS: Low-dose slow infusion of t-PA repeated as needed without a bolus provides effective and safe thrombolysis in patients with prosthetic valve thrombosis.

[Compensatory hemodynamic variations for cardiovascular stabilization in complete atrioventricular block before and after pacemaker implantation]. / Atriyoventriküler tam blokta kalici kalp pili öncesi ve sonrasinda kardiyovasküler sistem stabilizasyonunda hemodinamik kompansatuvar degisimler.

OBJECTIVES: Stabilization of the cardiovascular system is maintained by variations in hemodynamic and hormonal parameters in complete atrioventricular (AV) block. We investigated the variations in hemodynamic parameters and brain natriuretic peptide (BNP) levels before and after permanent pacemaker implantation for complete AV block. STUDY DESIGN: We evaluated 25 patients (14 men, 11 women; mean age 72+/-10 years; range 39 to 83 years) who presented with a complaint of syncope due to complete AV block. All the patients were hemodynamically stable on presentation and were monitored in the coronary care unit until permanent pacemaker implantation. Variations in the cardiovascular system were determined before and two weeks after pacemaker implantation, including mean arterial pressure (MAP), stroke volume (SV), cardiac output (CO), systemic vascular resistance (SVR), systemic aortic compliance (SAC), and BNP levels. RESULTS: The mean heart rates were 36+/-6 beat/min and 65+/-10 beat/min before and after pacing, respectively. Compared to the pacing period, CO was significantly lower (p<0.001) and SVR was significantly higher (p=0.001) before pacemaker implantation, suggesting a compensatory rise in SVR. The mean arterial pressure did not show a significant difference and remained within normal ranges before and after pacing. There were no significant differences in SV, SAC, and BNP levels before and after pacemaker implantation, with BNP exhibiting increased levels in both periods. CONCLUSION: While no compensatory alterations occur in SV, SAC, and BNP before and after pacemaker implantation, decreased CO in complete AV block seems to be balanced by increased SVR, which results in maintenance of MAP within the normal range.

Aneurysm of the right atrial appendage in an elderly patient.

A 72-year-old male patient presented with a complaint of pain in both legs during short walks of less than 50 meters. Physical examination showed weak arterial pulses in both lower extremities. Electrocardiographic and telecardiographic evaluations were normal. A previous abdominal ultrasonography examination performed for abdominal pain showed an abdominal aortic aneurysm. Coronary angiography findings were normal; however, peripheral angiography showed an abdominal aortic aneurysm and extensive critical bilateral peripheral artery disease. Transthoracic echocardiography disclosed an aneurysmal structure neighboring the right atrium. Transesophageal echocardiography demonstrated a 30x18-mm chamber suggestive of a right atrial appendage aneurysm. Cardiac magnetic resonance imaging confirmed the presence of the right atrial appendage aneurysm, 25x15 mm in size, over the tricuspid valve. The neck of the aneurysm was 11 mm. The patient underwent surgery which included grafting of the abdominal aorta and aortobifemoral bypass. He was discharged uneventfully on oral anticoagulant therapy.

Kounis syndrome secondary to amoxicillin/clavulanic acid use in a child.

The concurrence of acute coronary syndromes with allergic or hypersensitivity as well as with anaphylactic or anaphylactoid reactions is increasingly encountered in clinical practice and there are several reports associating mast cell activation with acute cardiovascular events in adults. It was first described by Kounis as "allergic angina syndrome" progressing to "allergic myocardial infarction". The main mechanism proposed is the vasospasm of coronary arteries. This condition has not been described in childhood. We present a 13-year-old boy, admitted to our hospital with thoracic pain, 30 min after the ingestion of an oral dose of 500 mg of amoxicillin/clavulanic acid.
