RESUMEN
Background Single-session hypnosis has never been evaluated as a premedication technique in patients undergoing coronary artery bypass grafting (CABG). The aim of the present study was to evaluate the beneficial effects of clinical hypnotherapy on perioperative anxiety, pain perception, sedation, and necessity for ventilator assistance in patients undergoing CABG. Methods Double-blind, randomized, clinical trial was performed. Forty-four patients undergoing CABG surgery were randomized into two groups. The patients in group A received preprocedural hypnosis by an anesthesiologist. Patients in group B (control) had only information on the surgical intervention by the same anesthesiologist. State-Trait-Anxiety Index-I (STAI-I) and Beck Depression Inventory (BDI) were performed preoperatively in both groups. Visual analog scale (VAS) and Ramsay sedation scale (RSS) were evaluated on 0th, 1st, 2nd, 4th, 6th, 8th, 10th, 12th, and 24th hours, postoperatively. Postoperative anxiety level, analgesic drug consumption, and duration of ventilator assistance and intensive care unit (ICU) stay were also documented. Results When anxiety and depression levels were compared, significantly lower STA-I and BDI values were detected in group A after hypnotherapy (p = 0.001, p = 0.001, respectively). Significantly less total doses of remifentanil (34.4 ± 11.4 vs. 50.0 ± 13.6 mg) and morphine (4.9 ± 3.3 vs. 13.6 ± 2.7 mg) were administered in group A in the postoperative period. Ventilator assistance duration (6.8 ± 2.0 vs. 8.9 ± 2.7 hours) was also shorter in group A when compared with that in group B (p = 0.007). Conclusion Hypnosis session prior to surgery was an effective complementary method in decreasing presurgical anxiety, and it resulted in better pain control as well as reduced ventilator assistance following CABG surgery.

Acute ischemia of an upper extremity occurs less frequently than vascular events of the leg and accounts for 15%-32% of all cases. Embolectomy provides prompt and effective treatment in the majority of cases. Recurrence of embolism and failed reperfusion can result in poor outcomes, even extremity loss. Adjunctive managements become important in this patient group. In this report, we present percutaneous intraarterial drip tissue plasminogen activator infusion to rescue the extremity in a patient with small cell lung cancer who experienced thromboembolism an additional six times following embolectomy.

BACKGROUND: Our aim is to evaluate the relationship between inspiratory muscle strength and venous refilling time, disease severity, and functional capacity in patients with chronic venous insufficiency (CVI). METHODS: Sixty-one patients (49 female, aged 20-65 ) were enrolled in the study. The demographic characteristics of the patients were questioned. All patients were assessed with maximum inspiratory and expiratory pressure (MIP/MEP) for inspiratory and expiratory muscle strength, photoplethysmography for venous refilling time (VRT), venous clinical severity score (VCSS) for disease severity, and 6-min walk test (6-MWT) for functional capacity. RESULTS: The mean age of the patients was 49.48 ± 13.19 years, and the mean duration of disease was 9.18 ± 6.57 years. There was statistically significant positive association between MIP and VRT(r: 0.331, p: 0.009), 6-MWT (r: 0.616, p < 0.001) values, and there was negative association between MIP and VCSS(r: -0.439 p < 0.001) scores. CONCLUSION: Evaluation of inspiratory muscle strength and elimination of its deficiency, providing interventions to approach normative values have the potential to contribute positively to the treatment of the patient.

OBJECTIVE: To evaluate the attitudes of physicians and patients toward physical examination in physically separated environments using a laryngoscopic examination model. MATERIALS AND METHODS: Six experienced laryngologists performed laryngoscopic examinations in 30 patients in a closed-chamber examination unit. The physicians and patients were asked to compare all domains with their previous standard laryngoscopic examination experience using a 10-point visual analog scale (0, poor performance; 10, good performance), including effectiveness of communication, difficulty of examination, perception of safety against airborne transmission of COVID-19, applicability of the unit for future examinations, perception of protective environment, and overall comfort. RESULTS: All laryngoscopic examinations were performed successfully. Effectiveness of communication, difficulty of examination, perception of protective environment, and overall comfort did not differ between physicians and patients (P > .05 for all comparisons). However, both physicians and patients found the examination to be difficult. While physicians evaluated the system as safe against airborne transmission of COVID-19, patients were not confident that the system was safe (8.70 ± 1.93 vs 2.87 ± 2.37, respectively, P = .001). Physicians also gave a higher score to future applicability of the unit for examinations than patients (8.90 ± 1.42 vs 7.10 ± 2.62, respectively, P = .001). CONCLUSION: Physically separating the physician and patient is a feasible method of physical examination in aerosol-contaminated environments.

OBJECTIVE: The aim of the present study was to evaluate the effects of inspiratory muscle training (IMT) and calf muscle exercise training (CMET), in addition to compression therapy (CT), on quality of life (QoL), venous refilling time, disease severity, pain, edema, range of motion, muscle strength, and functionality in patients with chronic venous insufficiency (CVI) compared with CT alone. METHODS: A total of 32 participants with a diagnosis of CVI were randomly divided into three groups: group 1, IMT plus CT; group 2, CMET plus CT; and group 3, CT alone. All 32 patients were assessed using the chronic venous disease QoL 20-item questionnaire, Nottingham health profile, photoplethysmography, venous clinical severity score, visual analog scale for pain, intraoral pressure measurements, dynamometer, digital goniometer, 6-minute walking test, and lower extremity functional scale. RESULTS: After treatment, group 2 had improved more than had groups 1 and 3 in QoL, venous refilling time, pain, edema, range of motion, muscle strength, and functionality. Group 1 had improved more than had groups 2 and 3 in disease severity and inspiratory and expiratory muscle strength values (P < .05). Only physical mobility and right leg venous refilling time had increased in group 3 (P < .05). CONCLUSIONS: The use of IMT and CMET had improved venous function in both legs in patients with CVI, and CT alone had improved venous function only in the right leg of patients with CVI.

OBJECTIVE: Mathematical models are known to help determine potential intervention strategies by providing an approximate idea of the transmission dynamics of infectious diseases. To develop proper responses, not only are more accurate disease spread models needed, but also those that are easy to use. MATERIALS AND METHODS: As of July 1, 2020, we selected the 20 countries with the highest numbers of COVID-19 cases in the world. Using the Verhulst-Pearl logistic function formula, we calculated estimates for the total number of cases for each country. We compared these estimates to the actual figures given by the WHO on the same dates. Finally, the formula was tested for longer-term reliability at t = 18 and t = 40 weeks. RESULTS: The Verhulst-Pearl logistic function formula estimated the actual numbers precisely, with only a 0.5% discrepancy on average for the first month. For all countries in the study and the world at large, the estimates for the 40th week were usually overestimated, although the estimates for some countries were still relatively close to the actual numbers in the forecasting long term. The estimated number for the world in general was about 8 times that actually observed for the long term. CONCLUSIONS: The Verhulst-Pearl equation has the advantage of being very straightforward and applicable in clinical use for predicting the demand on hospitals in the short term of 4-6 weeks, which is usually enough time to reschedule elective procedures and free beds for new waves of the pandemic patients.
RESUMEN
Background: Platelet-rich plasma (PRP) is an autologous concentrated preparation of platelets characterized by lymphangiogenetic and tissue-repairing effects. Although PRP has been safely used in many different fields, there is no clinical study regarding the use of PRP in lymphedema treatment in humans. We assessed the clinical outcomes of PRP in patients with lower extremity lymphedema (LEL) in a randomized controlled trial. Methods and Results: Patients with secondary LEL were randomly allocated to one of three groups consisting of treatment with PRP with complex decongestive physiotherapy (PRP+CDP group), low-level laser therapy with CDP (LLLT+CDP group), and only CDP (CDP group). Assessment of Lymphedema Quality of-Life Questionnaire (LYMQOL) for health-related quality of life, lower-extremity-circumference (LEC) for edema, tissue dielectric constant (TDC) for extremity volume, 6-minute walking test (6MWT) for functional capacity, and numeric rating scale (NRS) scoring for extremity fullness were evaluated both before and after treatment. Forty-five patients (68.8% female) with mean age 40.84 ± 15.81 years were included in the study. Significant differences in LYMQOL, LEC, NRS, and TDC values both before and after treatment were found in all groups; however, there were no statistically significant difference in values between the three groups. In the PRP+CDP group, LYMQOL values had a larger effect size than the other two groups. Significant differences in 6MWT values both before and after treatment were found in PRP+CDP and LLLT+CDP groups; however, there was no statistically significant difference in the CDP group. Conclusion: This is the first clinical study to evaluate the usage of PRP in patients with secondary LEL. PRP might be an additional treatment option of lymphedema management; however, more clinical trials in humans are needed to yield more evidence in the usage of PRP in patients with lymphedema.

OBJECTIVE: Risk factors and results of cardiac surgery with cardiopulmonary bypass (CPB) in hemodialysis-dependent renal failure patients at our center were evaluated. METHODS: Out of 16,425 patients undergoing open heart surgery with CPB at our center between January 1991 and April 2006, 91 (0.6%) experienced hemodialysis-dependent end-stage renal failure. Preoperative, operative, and postoperative findings of two groups of patients were evaluated: those with normal renal function (control group) and those with chronic renal failure undergoing regular hemodialysis (HDRF group). Survival analyses of the hemodialysis group of patients were performed. RESULTS: In the hemodialysis group, 54 (59.3%) patients underwent coronary artery surgery, 31 (34.1%) patients had valve surgery, four (4.4%) patients had aortic surgery, and two others (2.2%) experienced concomitant coronary and peripheral artery surgery. CPB and aortic cross-clamping (ACC) times were longer in the HDRF group (p=0.000 and 0.002, respectively). There was no significant difference between the two groups with regard to either reoperations, infections, pulmonary and gastrointestinal system complications, or cerebrovascular event parameters (p=0.167, 0.341, 1.000, 1.000, and 1.000, respectively). There was no difference between groups in the postoperative development of low cardiac output (p=0.398). The early mortality rate was 7.7% (seven patients) in the HDRF group and 4.8% (780 patients) in the controls (p=0.211). The actuarial survival rates in HDRF survivors at one, two, three, four, five, and ten years were overall 86%, 80%, 68.1%, 45.4%, 20%, and 6.8%, respectively. CONCLUSIONS: Open heart surgery in hemodialysis patients is associated with a higher incidence of risks, but can be performed with acceptable operative complications and mortality with an effective hemodialysis program.

OBJECTIVE: Our aim was to evaluate the significance of homocysteine (Hcy) in Behcet's disease (BD) and the association of elevated Hcy levels associated with the indices of inflammation in BD. METHODS: Untreated 70 patients with BD and 33 healthy individuals were included into the study. Hcy, tumor necrosis alpha (TNF-alpha), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were evaluated with respect to activity and specific individual clinical manifestations of the disease. RESULTS: Hcy levels were found significantly elevated in active BD when compared to inactive BD and healthy controls. Hcy levels were found to have high correlation with the number of active clinical manifestations increased. A significant positive correlation was found between serum Hcy and TNF-alpha levels, CRP, and ESR. Hcy was found to be the best predictor of TNF-alpha among other parameters. CONCLUSION: Hcy may involve in the pathogenesis of BD by inducing inflammation.

OBJECTIVE: The aim of the study is to find out the efficacy of radiofrequency catheter atrial ablation (RF) simultaneously done with mitral valve replacement (MVR) surgery in patients having rheumatic mitral valve disease with chronic atrial fibrillation and to evaluate the short-term postoperative results. METHODS: Seventeen patients underwent MVR surgery, and intraoperative RF procedures were done simultaneously with MVR to eight of these patients, whereas remaining nine of them were assigned to control group. Patients were assessed preoperatively, at time of discharge, and 1st, 6th and 12th months controls. Atrial and ventricular functions were evaluated with echocardiography, serum atrial natriuretic peptide (ANP) levels were investigated and electrocardiograms were recorded in all patients. RESULTS: Demographically there were no significant differences between two groups. Radiofrequency ablation group had longer aortic cross-clamping and cardiopulmonary bypass times. Sinus rhythm was established in seven patients of RF group at postoperative 12th month. However, all patients of this group experienced sinus rhythm at postoperative sixth month whereas 'atrial kick' was detected in five of them. Significantly increased ejection fraction, decreased pulmonary artery pressure and decreased left atrial diameter were observed in RF group compared to control group. Serum ANP levels were found to be significantly decreased as compared to preoperative periods in both groups. CONCLUSION: Although RF ablation has higher costs, this technique is efficient and useful to restore the sinus rhythm and to recover the atrial functions back in patients having rheumatic mitral valve disease.

Platelet-rich plasma (PRP) is an autologous concentrated preparation of human platelets contained in a small volume of plasma that is characterized by hemostatic and tissue-repairing effects. Being enriched by various kinds of growth factors, and their tissue-repairing effects have made them the focus of attention for use in tissue regeneration. PRP has been safely used and documented in many different fields, including orthopedics, sports injuries, dental and periodontal surgery, and cosmetic, plastic, cardiovascular, general, and maxillofacial surgery. The current evidence obtained from in vitro and animal studies pointed out that PRP may potentially be used to regenerate injured lymphatic vessels to treat or prevent lymphedema. Therefore, we have reviewed existing literature on the clinical uses of PRP in lymphedema and inquired whether there is enough evidence to support the use of PRP in clinical practice as a treatment option. In contrast to in vitro and animal models, there is no clinical trial regarding the use of PRP in lymphedema treatment. Only two animal studies matched to our research yielded positive and promising results in terms of the potential role of PRP in future for lymphedema therapies. In the light of these findings, it is clear that this is an important issue that should be studied in greater depth to clarify the efficacy of PRP in the management of lymphedema.

Mast cells have been implicated as important in tissue remodeling and fibrosis. We investigated the effect of mechanical ventricular unloading upon myocardial fibrosis and cardiac mast cell density in patients undergoing left ventricular assist device (LVAD) implantation. Paired myocardial tissue samples were obtained from 30 patients with end-stage cardiomyopathy at the time of LVAD implantation and at the time of removal and were compared with samples taken from donor hearts. Tissue sections were stained and quantitated for mast cells and myocardial fibrosis. Mast cell density (tryptase positive cells) in cardiomyopathy was higher than that in donor hearts (33.5 +/- 3.6 SEM cells/10 fields vs.15.2 +/- 2.0 SEM cells/10 fields respectively, p = 0.04) and was lower than LVAD supported hearts (33.5 +/- 3.6 SEM cells/10 fields vs. 49.8 +/- 5.7 SEM cells/10 fields respectively, p = 0.01). Mast cells are primarily localized in areas of increased interstitial fibrosis adjacent to myocardial cells and not vessels. There was statistically significant correlation between mast cells and interstitial collagen (p = 0.03) in patients before LVAD implantation that did not persist after mechanical support (p = 0.18). These results suggest that mechanical support with left ventricular assist devices induces an increase in mast cell number in the myocardium and an associated decrease in myocardial fibrosis. We believe these data demonstrate a dual role for cardiac mast cells in the increase in fibrosis in heart failure and the decrease after LVAD and its associated cardiac improvement.

BACKGROUND: Mast cells have been implicated in tissue remodeling and fibroblast stimulation. We explored the effect of mechanical support by left ventricular assist device (LVAD) in failing myocardium and looked into grade and distribution of interstitial fibrosis, mast cell density, mast cell phenotypes and basic fibroblast growth factor (bFGF) expression pre- and post-LVAD. METHODS: Myocardial tissue was obtained from 20 patients with end-stage cardiomyopathy at the time of LVAD implantation and LVAD removal and from 7 donor hearts not used for transplantation. Tissue sections were stained for mast cells using tryptase as a marker and the myocardial fibrosis was measured. Double staining for tryptase and chymase was performed for detection of chymase-positive mast cells. Fluorescent microscopy showed the relationship of mast cells to bFGF, and bFGF expression was quantified by Western blot. RESULTS: There was a significant increase in mast cells in heart failure vs normal myocardium. A secondary increase in mast cells occurred after long-term (>40 days) support compared with matched pre-LVAD samples (mean +/- SEM; 57.4 +/- 8.6 cells/10 fields vs 45.1 +/- 7.6 SEM cells/10 fields, p < 0.01). The secondary increase in mast cells was associated specifically with an increase in chymase-negative mast cells (p < 0.01). These findings are statistically significant with concurrent decreased expression of bFGF and decreased fibrosis in the same patient tissues (p < 0.01). CONCLUSIONS: We suggest that, under long-term support, there is a change in phenotypic expression in mast cells, which can alter fibroblast functions. The decreased myocardial bFGF levels might be the result of these phenotypically altered mast cells.

BACKGROUND: Although many reports demonstrate the hemodynamic benefits of left ventricular assist devices (LVAD) in right-sided circulation, it is not known whether the right ventricular myocardium goes through reverse remodeling after left ventricular mechanical circulatory support. Accordingly, the purposes of our studies were 1). to investigate the right ventricular changes that occur in fibrosis, in cellular hypertrophy, and in intra-myocardial tumor necrosis factor alpha (TNF-alpha) levels in patients receiving LVAD support; and 2). to determine whether the type of LVAD used influences right ventricular myocardial changes. METHODS AND RESULTS: We measured myocyte size, total collagen content, and TNF-alpha levels using semi-quantitative immunohistochemical analysis of myocardial samples from the right and left ventricles of control and failing myocardia, either supported by 1 of 2 distinct forms of LVADs or without support. We found that when compared with control, although myocyte size was not increased in the right ventricle of failing myocardia (p = not significant), total collagen content and myocardial TNF-alpha levels were decreased in the right ventricle compared with controls (p < 0.01 and p < 0.001, respectively). CONCLUSION: These data demonstrate that chronic left ventricular unloading with either pulsatile or continuous-flow devices decreases right ventricular total collagen and myocardial TNF-alpha content. We suggest that the decreased fibrosis and normalization of cytokine milieu observed may in part contribute to the recovery of right-sided cardiac function associated with chronic mechanical circulatory support.

We describe a complex congenital pelvic AVM with multiple feeding arteries arising from the side branches of the right internal iliac artery and a single draining vein in a male patient. Concomitant transarterial and transvenous embolization with a new liquid embolic agent Squid-12 and metallic coils enabled a complete embolization at a single session. Squid-12 is composed of ethylene vinyl alcohol copolymers and its lower viscosity makes it a promising agent for the treatment of AVMs. The patient showed prompt resolution of the symptoms and complete devascularization of the AVM lesion was persisted on the 1-month control angiography. The patient was asymptomatic on the 6th month follow-up.
