RESUMO

Ingestion of a corrosive substance may cause corrosive esophagitis. Curcumin has anti-inflammatory and mucosal protective effects. In this study, the effects of curcumin on the acute phase of corrosive esophagitis were investigated. Twenty-seven Wistar Albino rats were divided into four groups; sham (group I), control (group II), and experiment groups (group III, 100 mg/kg curcumin; group IV, 200 mg/kg curcumin). Forty percent sodium hydroxide solution was used to erode the esophagi of rats in groups other than the sham group. Curcumin was applied to animals in the experiment groups 10 min after the corrosion. After 24 h, animals were sacrificed, and esophagus samples were collected. According to the histopathological examination, the muscularis mucosa damage was regressed from 100% in group II to 71.4% in group III and 50% in group IV. Mild level of damage and collagen deposition in the tunica muscularis regressed from 66.7% of the animals in the control group to 42.9% in group III and to none in group IV. Further, an increase in submucosal collagen was present in all samples from groups II and III, while 83.3% of samples had an increase in submucosal collagen in group IV. There was a significant difference in the histopathological total score between the control group and group IV (p=0.02). The results showed that the administration of curcumin in a dose-dependent manner can relieve the acute phase of corrosive esophagitis.

RESUMO

BACKGROUND: We compared the effect of intermittent blood and histidine-tryptophan-ketoglutarate (HTK) solution of Bretschneider on myocardial histopathology and perioperative outcome. METHODS: Forty adult cardiac surgery patients were grouped into two (n = 20 for each): (1) Intermittent blood cardioplegia (IBC): had repeated cold 4:1 blood cardioplegia and (2) HTK: had a single dose of cold HTK for cardioprotection. Creatine kinase (CK)-MB, Troponin-I (cTn-I), pH, and lactate were studied in coronary sinus blood before and after aortic cross-clamping (AXC) and systemic blood at postoperative 6th, 24th, and 48th hours. Myocardial biopsy was performed before and after AXC for light microscopy. Vacuolation, inflammation, edema, and glycogen were graded semiquantitatively (from 0 to 3). The myocardial apoptotic index was evaluated via the terminal deoxynucleotidyl transferase dUTP nick end labeling. RESULTS: There were no differences in perioperative clinical outcomes between the groups. The coronary sinus samples after AXC were more acidotic (7.15 ± 0.14 vs. 7.32 ± 0.07, p = 0.001) and revealed higher CK-MB (21.0 ± 12.81 vs. 12.60 ± 11.80, p = 0.008) in HTK compared with IBC. The HTK had significantly a higher amount of erythrocyte suspension intraoperatively compared with IBC (0.21 ± 0.53 vs. 1.68 ± 0.93 U, p = 0.001). Microscopically, myocardial edema was more pronounced in HTK compared with IBC after AXC (2.25 ± 0.91 vs. 1.50 ± 0.04, p = 0.013). While a significant increase in the apoptotic index was seen after AXC in both groups (p = 0.001), no difference was detected between the groups (p = 0.417). CONCLUSION: IBC and HTK have a similar clinical outcome and protective effect, except for more pronounced myocardial edema and increased need for intraoperative transfusion with HTK.

RESUMO

OBJECTIVE: Ablation with n-butyl cyanoacrylate is a clinically newer technique than endovenous laser ablation and other interventional techniques in the treatment of chronic venous insufficiency (CVI). The aim of this study was to compare the endovenous laser ablation (EVLA) and n-butyl cyanoacrylate (NBCA) interventional techniques in terms of benefit, effectiveness, and patient satisfaction. MATERIALS AND METHODS: The study was conducted at Yozgat City Hospital and Bozok University Research Hospital Cardiovascular Surgery clinics between November 2016 and February 2021. A total of 260 symptomatic patients with 130 randomized cases in each intervention group were included. NBCA patients constituted Group 1 and EVLA patients Group 2. The saphenous vein was evaluated by color Doppler ultrasonography (CDUS) of the lower extremity. Patients with saphenous veins over 5.5 mm in diameter and a saphenous-femoral reflux time of 2 s or longer were included in the study. The patients were asked about their satisfaction and symptoms in the first postoperative week during an outpatient clinic follow-up with CDUS investigation at the first and sixth months. RESULTS: Although vena saphenous magna (VSM) closure results were similar with the two methods, satisfaction rates were found to be higher with the NBCA procedure. CONCLUSION: Comparison of the new methods used in the treatment of CVI revealed similar VSM closure rates in the two methods, but the satisfaction rate was higher with the NBCA technique in this study.

RESUMO

OBJECTIVE: The aim of this study was to compare the long-term outcomes of below the knee revascularization with percutaneous atherectomy followed by drug-coated balloon and revascularization with drug-coated balloon alone for symptomatic diabetic patients with peripheral arterial disease. PATIENTS AND METHODS: Between April 2015 and January 2020, total of 128 patients and 228 below the knee procedures were enrolled into this retrospective study. Sixty-five patients were treated with atherectomy followed by drug-coated balloon and 63 patients were treated solely with drug-coated balloon. RESULTS: Technical success rates were similar in the AT+DCB group and DCB group. Target lesion revascularization (TLR) was found similar in both groups at 6-month follow-up. Clinically, driven repeat endovascular and surgical limb revascularization rates were also significantly lower at 12 and 24 months. CONCLUSION: Combined usage of rotational atherectomy and drug-coated balloons for the treatment of diabetic patients with below-the knee arterial lesions and critical limb ischemia is associated with reduced long-term TLR rates and improved the long-term outcomes.


OBJETIVO: El objetivo de este estudio fue comparar los resultados a largo plazo de la revascularización por debajo de la rodilla con aterectomía percutánea seguida de balón recubierto de fármaco y revascularización con balón recubierto de fármaco solo en pacientes diabéticos sintomáticos con arteriopatía periférica. MÉTODOS: Entre abril de 2015 y enero de 2020, un total de 128 pacientes y 228 procedimientos por debajo de la rodilla se inscribieron en este estudio retrospectivo. Sesenta y cinco pacientes fueron tratados con aterectomía seguida de balón recubierto de fármaco y 63 pacientes fueron tratados únicamente con balón recubierto de fármaco. RESULTADOS: Las tasas de éxito técnico fueron similares en el grupo AT+DCB y DCB. La revascularización de la lesión diana fue similar en ambos grupos a los 6 meses de seguimiento. Las tasas de revascularización endovascular y quirúrgica de las extremidades también fueron significativamente más bajas a los 12 y 24 meses. CONCLUSIÓN: El uso combinado de aterectomía rotacional y balones recubiertos de fármaco para el tratamiento de pacientes diabéticos con lesiones arteriales por debajo de la rodilla e isquemia crítica de las extremidades se asocia con tasas reducidas de revascularización de la lesión diana a largo plazo y mejores resultados a largo plazo.

RESUMO

OBJECTIVE: To evaluate the differences in neurocognitive abilities between the preoperative and postoperative periods following carotid endarterectomy (CEA), due to carotid artery stenosis, and to evaluate the effectiveness of CEA on neurocognitive abilities in the future. MATERIAL AND METHODS: Thirty-eight cases of CEA surgery at Bozok University Faculty of Medicine Research Hospital between January 2015 and June 2020 were examined. Neurocognitive tests were performed on carotid endarterectomy patients one day before the operation and on the 2nd, 4th, and 30th postoperative days. The effect of CEA on cognitive results has been investigated. RESULTS: Of the patients, eight were female (21.1%), 30 were male (78.9%), and the mean age was 66 ± 4.09. Thirty-two (84.21%) of the patients were operated on under general anesthesia and six (15.78%) under regional anesthesia. A shunt was used in 19 patients. Right carotid endarterectomy was performed in 20 cases and left carotid endarterectomy in 18 cases. We used the primary closure technique in two of 38 cases and patches on 36 of them. We used Dacron in 21 cases, PTFE in 12 cases, and saphenous vein as a patch in three cases. In the WMS digit spam and recall scores, the postoperative period fell on the 2nd day, and then on the 4th and 30th day after the operation, there was a low level of increase over time. Compared with the preoperative period, the learning score was found to be the lowest on the 2nd day, lower on the 4th day compared with the preoperative period and improved compared with the preoperative period on the 30th day. There was no decrease in the verbal fluency test score results after the operation, on the contrary, it was observed minimally. The test score results cumulatively were decreased in the early postoperative periods compared with the preoperative period and increased on the 30th day compared with the preoperative period. CONCLUSION: The purpose of CEA in the past was the prevention of ischemic stroke and cerebrovascular disease (CVD) rather than neurocognitive recovery. Factors affecting neurocognition in CEA are multifactorial. Preservation and improvement of neurocognition are more important than any other period of history. By prioritizing cognitive abilities in the treatment of carotid stenosis, individualization of the treatment will help maximize the increase in cognitive abilities by providing optimum benefit to the patient of each factor.

RESUMO

A coexisting coronary heart disease may increase the operative mortality and morbidity rates of lung resection. A simultaneous or a two-stage procedure using myocardial revascularization prior to the pulmonary resection may reduce the postoperative morbidity and mortality. Herein, we present a 65-year-old male case of a lung adenocarcinoma in whom a simultaneous coronary artery bypass grafting on a beating heart and right upper lobectomy was performed.

RESUMO

Behçet's Disease (BD) is a multisystemic vasculitis which usually affects optical, genital, and oral mucosae and often reoccurs intermittently. Chylothorax is a very rare complication of BD which usually causes thrombosis in the major venous system. A 27-year-old man with a 10-year history of BD referred to our cardiovascular surgery department with symptoms of serious aches in the left arm, edema, and apparent veins on the left anterior chest wall. A total thrombosis of the left internal and external jugular veins and the left subclavian vein was observed. One month after a successful treatment and discharge, the patient returned to our clinic with symptoms of dyspnea and coughs. A chest radiograph showed a consolidated region. A milky liquid was aspirated through thoracocentesis from the left thorax, and its biochemical analysis helped us arrive at a diagnosis of chylothorax. The patient was hospitalized and administered corticosteroids and immunosuppressive therapy with a high-carbohydrate and low-fat dietary regimen for BD. Thereafter, a left thoracic drainage system was established. On the seventh day of hospitalization, due to a progressing cheilosis flow, a pleurodesis process was applied with talcum powder. However, the chylous drainage was continued and 60 mL of venous autologous blood was injected into the left thorax through a drainage tube. The treatment was successful, and the patient was discharged from the hospital uneventfully. At 1 month's follow-up, the chest radiograph was normal.
