RESUMEN

OBJECTIVE: The risk of operation in cardiac surgery increases logarithmically with advanced age. In older individuals, additional comorbidities compel the clinician to deal with postoperative complications. The mortality and morbidity rates of emergency coronary artery bypass surgery (CABG) in the presence of acute coronary syndrome (ACS), or just after it, are higher than those of elective surgeries. In our study, we compared the outcomes of off-pump coronary bypass (OPCAB) and on-pump coronary bypass surgery (ONCAB) in this high-risk subgroup. PATIENTS AND METHODS: 383 octogenarians who underwent isolated emergency CABG due to ACS were divided into two groups according to the coronary bypass technique. Group 1 (off-pump) median age (IQR) 84 years (min: 80-max: 99, n = 130); Group 2, (on-pump) median age 85 years (min: 80-max: 89, n=253). Preoperative, intraoperative, and postoperative data were collected retrospectively on standard variables. OPCAB and ONCAB outcomes were compared. RESULTS: ONCAB patients had a significantly longer intensive care unit stay, longer hospital stay, more transfused erythrocyte suspension, more low cardiac output syndrome and acidosis, a higher rate of acute renal failure and a higher rate of stroke than OPCAB patients (respectively; p=0.003; p=0.008; p=0.002; p=0.031; p=0.038, p=0.022, respectively). CONCLUSIONS: We showed that emergency OPCAB as a revascularization option in elderly patients with acute coronary syndrome is more advantageous in terms of preventing major postoperative complications.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the effectiveness of alprazolam, administered at different doses, for the control of adjuvant analgesia in laparoscopic donor nephrectomy patients preoperatively in the Akdeniz University Organ Transplantation Center, using various pain scales. MATERIALS AND METHODS: Only patients with a body mass index ≤28 kg/m2, aged between 18 and 65 years old, and with an American Society of Anesthesiologists score of 1 to 2 were included in the study. The patients were studied in 3 groups, which were given 0.5 mg alprazolam (group 1), 1 mg alprazolam (group 2), or no alprazolam (group 3) in the preoperative period. Collected data were evaluated for preoperative, intraoperative, and postoperative periods. RESULTS: There were 75 patients (31 men, 44 women). Mean age was 43.1 years. Twenty-five patients were evaluated in all 3 groups. Mean operation time was 137.8 minutes. There was no statistical difference among the groups in the duration of administered alprazolam before the operation, on the Ramsey sedation score, verbal pain score, or numeric pain score, and duration of administered first analgesic in the postoperative period. Additional dose of analgesics were administered in 7, 7, and 11 of the patients in group 1, group 2, and group 3, respectively. We found a significant difference between groups 1 and 2 in blood pressure (P = .017 and P = .014). We found a significant difference in group 1 in heart rate (P = .002). CONCLUSION: More effective analgesia protocols need to be identified for pain control in patients of laparoscopic donor nephrectomy. It is thought that the effectiveness of pain control may increase the number of donors and progress in the treatment of patients with renal failure.

RESUMEN

BACKGROUND AND OBJECTIVE: The aim of our study was to assess the cardiac and neurologic complications after liver transplantation in the late period. METHOD AND PATIENTS: Medical records of 198 patients who had liver transplantation in the organ transplantation center of our university hospital between between February 2014 and October 2017 were reviewed retrospectively. Patients who were consulted by a physician from either the cardiology or neurology departments during their long-term follow-up after liver transplantation were included in the study. RESULTS: Thirty patients (9 female; 30.0%) were evaluated by a cardiologist (n = 23; 76.7%) or a neurologist (n = 19; 63.3%) during their long-term-follow-up. The mean age was 55.0 ± 13.3. Atherosclerotic risk factors such as hypertension (n = 10; 33.3%), diabetes mellitus (n = 17; 56.7%), hyperlipidemia (n = 7; 23.3%), and coronary artery disease (n = 7; 23.3%) were highly prevalent. Chest pain (n = 5; 16.7%) was the most encountered symptom. Of these patients, 2 (6.7%) underwent coronary bypass surgery, whereas 1 (3.3%) patient was treated medically. Palpitation was the second most frequent cardiac symptom (n = 3; 10.0%). Atrial fibrillation paroxysm occurred in 2 patients. Headache (n = 4; 13.3%) was the most prevalent neurologic symptom. Transient ischemic attack occurred in 1 patient (3.3%), whereas 2 patients (6.7%) experienced stroke (1 ischemic and the other hemorrhagic). Seizures occurred in 2 patients (6.7%). CONCLUSION: Long-term follow-up of liver transplant recipients might be challenging due to the diversity of symptoms and wide spectrum of cardiac and neurologic complications. A multidisciplinary approach involving cardiologists and neurologists would help to improve early preventive measures and medical treatment strategies.

RESUMEN

PURPOSE: To determine the value of diffusion-weighted magnetic resonance imaging (DW-MRI) in discriminating between hepatic alveolar echinococcosis (AE) and hepatocellular carcinoma and intrahepatic cholangiocarcinoma. METHODS: We included 49 patients (27 men, 22 women; mean age: 52.02±9.76 [SD] years; range: 25-72years) with 57 histopathologically confirmed hepatic AE lesions. Fifty patients (18 men, 32 women; mean age: 58.93±8.42 [SD] years; range: 42-71years) with 61 histopathologically confirmed hepatocellular carcinoma and 50 patients (24 men, 26 women; mean age: 50.11±7.70 [SD] years; range: 38-69years) with 54 histopathologically confirmed intrahepatic cholangiocarcinoma lesions were used as control groups. All patients had MRI examination of the liver that included conventional MRI sequences and DW-MRI using b values of 50, 400 and 800s/mm2. Two radiologists evaluated conventional MRI and DW-MRI images and calculated ADC values of hepatic lesions. RESULTS: The mean ADC value of solid components of hepatic AE lesions was 1.34±0.41×10-3 mm2/s (range: 0.9-1.59×10-3 mm2/s) and was significantly higher than that of the solid components of hepatocellular carcinoma lesions (mean ADC value, 0.99±0.29×10-3 mm2/s; range: 0.7-1.15×10-3 mm2/s) and of intrahepatic cholangiocarcinoma lesions (mean ADC value, 1.05±0.22×10-3 mm2/s; range: 0.86-1.18×10-3 mm2/s) (P<0.001). CONCLUSION: In general ADC values can help discriminate between AE and hepatocellular carcinoma and intrahepatic cholangiocarcinoma. However, the use of ADC values cannot help differentiating Type 4 AE from hepatocellular carcinoma or intrahepatic cholangiocarcinoma.

RESUMEN

INTRODUCTION: Smoking increases the risk for cardiovascular disease in kidney donors, as is the case with normal individuals; it may also result in the development and progression of chronic renal failure. The present study aimed to investigate the effect of kidney transplant on smoking habits of kidney donors. METHOD: The study included 98 donors in total (54 female, 44 male). A questionnaire was administered to donors about smoking status. Smoking status was asked about before surgery and 12 months postoperatively, and the preoperative and postoperative values were compared. The Fagerstörm test for nicotine dependence was administered to individuals who were still smokers and those who had smoked but quit. RESULTS: The mean age of the participants was 48.27 ± 10.8 years. The preoperative smoking status was 47% (n = 46), whereas the postoperative rate decreased to 29% (n = 28). This reduction in smoking rate was significant (P = .001). There was no difference in Fagerström levels between donors who continued smoking and those who quit smoking after the surgery (P = .583). CONCLUSIONS: A person who becomes a kidney transplant donor has the chance to quit smoking, which is a cardiovascular risk factor. In addition to the psychosocial benefits of being a donor, it should be noted that it might also provide some medical benefits. However, some patients continue smoking after surgery. Smoking should be questioned in the postoperative follow-ups of donors and the support required for smoking cessation should be provided.

RESUMEN

AIM: Cardiovascular diseases and infections are the leading two causes of morbidity and mortality in end-stage renal disease (ESRD) patients. Kidney transplantation is the preferred method for renal replacement owing to better survival. There are reports of irreversibly damaged immune system in dialysis patients, which did not return to normal even after kidney transplantation. The neutrophil-lymphocyte ratio (NLR) is an easily applicable method for evaluation of inflammation. We hypothesized that preemptive kidney transplantation can improve inflammatory state compared with nonpreemptive recipients. To test our hypothesis, we retrospectively investigated pretransplant and posttransplant NLR and C-reactive protein (CRP) levels of ESRD patients and compared them with values in healthy controls. MATERIALS AND METHODS: We retrospectively analyzed NLR, CRP, and other hematologic parameters of ESRD patients who were transplanted between January 2005 and January 2014 on the day of transplantation and at the end of first year. We grouped the patients as preemptive and nonpreemptive ones. We excluded patients with coronary artery disease, obesity, hypotension, hyperthyroidism, uncontrolled diabetes mellitus, hematologic or solid organ cancers, and active documented infection at any evaluation period. RESULTS: We included 137 ESRD patient and 34 healthy control individual in our study. Of the 137 ESRD patients, 52 (38%) were transplanted preemptively. Of the patients, 85 were already on either hemodialysis or peritoneal dialysis therapy at the time of transplantation. The white blood cell count value of the patient and control group (7246.72 ± 1460.26 and 76661.76 ± 1286.29, respectively; P = .43), NLR of the control group was significantly lower than patient group (1.98 ± 0.94 and 3.47 ± 2.33, respectively; P = .007). The NLR of the preemptive group was decreased substantially at the end of first year posttransplantation, the NLR of the preemptive group was significantly lower than the nonpreemptive group (3.08 ± 1.32 and 3.71 ± 2.33; P = .01). CONCLUSIONS: We showed that all ESRD patients had an increased inflammation rate according to CRP and NLR when compared with healthy controls. We also found that improvement of inflammatory state in preemptive patients is significantly better than nonpreemptive patients at the end of first year evaluation.

RESUMEN

BACKGROUND: Chronic kidney disease (CKD) is a worldwide disorder which is characterized by the presence of systemic low-grade inflammation. There is also acquired immune deficiency in this patient group which is clinically present with increased incidence of severe infections, poor response to vaccination, and increased risk of virus-associated cancers. Renal transplantation is one of the renal replacement modalities that restore renal functions. Mean platelet volume (MPV) is emerging as a marker of inflammation in many clinical conditions. In this study we aimed to disclose the improvement of paired immune response of ESRF patients after renal transplantation even though they are under immunosuppressive therapy. METHODS: We retrospectively investigated C-reactive protein, MPV, platelets (PLT), and other hematologic parameters on the day of transplantation and at the end of the 1st and 2nd years after transplantation of 58 preemptive and 112 nonpreemptive renal transplant patients. We compared them with a healthy control group. RESULTS: The MPV of the control group was 8.00 ± 0.73. The mean MPV of transplant patients before transplantation and at the end of the 1st and 2nd years after transplantation were 7.66 ± 1.01, 8.06 ± 0.97, and 8.20 ± 0.84, respectively. The initial MPV of the patient group was statistically significantly lower than the control group (P = .04). There was a statistically significant increase of MPV after transplantation. At the end of the 2nd year the difference of MPV between the patient and control groups was gone. CONCLUSIONS: We detected that CKD patients had a decreased MPV compared with normal individuals and that it normalized at the end of the 2nd year after renal transplantation. We speculated that the decreased MPV in CKD patients is related to increased inflammation and uremic toxins owing to uremia which was improved after renal transplantation.

RESUMEN

OBJECTIVES: The aim of this study was to investigate quantitative cytologic changes in oral mucosal smears collected from kidney transplant patients by modern stereologic methods. METHODS: We enrolled 32 kidney transplant patients. Smears were obtained from the buccal mucosa transplant patients before and 12 months after kidney transplantation. Smears from each individual were stained using the Papanicolaou method and were analyzed using a stereological method. RESULTS: Statistically, the nuclear volumes and cytoplasmic volumes in the cells of buccal mucosa were markedly higher after kidney transplantation (P < .05). There was a decreased positive cell density in the oral epithelial cells after kidney transplantation compared with before renal transplantation (P < .05). CONCLUSIONS: These findings suggest that there are alterations in the oral epithelial cells after kidney transplantation, which are detectable by microscopy and cytomorphometry.

RESUMEN

BACKGROUND: Vascular complications are a primary diagnostic consideration in liver transplant recipients, with an overall incidence of 9%. Cross-sectional imaging techniques provide information regarding vascular structure and luminal patency but can not quantitatively assess hepatocyte damage in the liver graft parenchyma. Perfusion computerized tomography (CT) is a recently developed method that allows for quantitative evaluation of hemodynamic changes in tissue. Our objective was to evaluate the clinical utility of perfusion CT in assessing vascular complications during living-donor liver transplantation (LDLT). METHODS: The 33 recipients were divided into 3 groups according to Doppler ultrasonographic findings: hepatic arterial complication group, portal venous complication group, and hepatic venous complication group. Blood volume (BV), blood flow (BF), arterial liver perfusion (ALP), portal venous perfusion (PVP), and hepatic perfusion index (HPI) were calculated for the affected vascular territory regions. RESULTS: Compared with normal liver parenchyma, BV, BF, ALP, and HPI were significantly lower in the hepatic arterial complication group. Although PVP and BV were significantly lower, ALP, HPI, and BF were higher in the affected vascular territory region than in normal liver parenchyma for the portal venous complication group. In the hepatic venous complication group, PVP was significantly higher and BF, ALP, and HPI significantly lower in the affected vascular territory regions than in normal liver parenchyma. CONCLUSIONS: Perfusion CT imaging is a noninvasive technique that enables the quantitative evaluation of vascular complications in the graft parenchyma after LDLT and permits a quantitative evaluation of the treatment response.

RESUMEN

AIM: To evaluate the role of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance cholangiography (MRC) in the evaluation of biliary-cyst communication (BCC) before treatment for hepatic hydatid disease (HHD). MATERIAL AND METHODS: Thirty-one patients with clinical and laboratory follow-up for HHD with suspected diagnosis of BCC underwent three-dimensional (3D) T2-weighted MRC and T1-weighted contrast-enhanced MRC, dynamic 3D gradient echo (GRE) sequences, using Gd-EOB-DTPA to identify the presence or absence of BCC. A total of 45 hepatic hydatid cysts in the 31 patients were evaluated for cyst diameter, BCC, and the time to contrast-enhancement of the hydatid cyst after Gd-EOB-DTPA injection. The surgical and interventional radiological procedures and imaging findings were compared. The sensitivity, specificity, and accuracy of both techniques in identification of BCC were calculated. RESULTS: The accuracy of contrast-enhanced MRC for identifying BCC was superior with a sensitivity of 87.4% and accuracy of 90.5% (p < 0.05). A diameter of ≥10 cm was associated with significantly increased risk of BCC on contrast-enhanced MRC images (p < 0.05). CONCLUSION: The use of Gd-EOB-DTPA-enhanced MRC yields information that complements T2-weighted MRC findings and improves identification of BCC. The use of T2-weighted MRC, in addition to contrast-enhanced MRC, is recommended to increase preoperative accuracy of identifying BCC.

RESUMEN

Brucellosis is considered the most widespread zoonosis in the world. It has been reported that the prevalence of seropositivity among the Turkish population varies from 3% to 14%. We present a case of brucellosis after pediatric liver transplantation. A 15-year-old boy with the diagnosis of neuro Wilson's disease underwent deceased-donor liver transplantation. The postoperative immunosuppressive protocol consisted of steroids and tacrolimus. Two months after the operation the patient experienced fever to 40°C. The patient complained of poor appetite, headache, and diarrhea. He had had pancytopenia. Despite administration of appropriate antibiotics, antiviral and antifungal agents, fever persisted for > 1 month. Multiple blood, urine, stool, and sputum cultures were negative. Bone marrow aspirate revealed hypocellularity. Liver biopsy was performed, but rejection was not observed on biopsy specimen. Brucella serology was positive and Brucella agglutination titer was 1:320. Bone marrow culture was positive for Brucella but blood culture was negative. The patient was then treated with oral doxycycline and rifampin for 8 weeks. No previous case report about Brucella infection after liver transplantation has appeared in the literature, to our knowledge; our case is presented as the first. Bone marrow hypoplasia is a rare feature of Brucella infection. Our patient with brucellosis and pancytopenia had had hypocellular bone marrow. The clinical and hematologic findings resolved with treatment of the infection. Brucella infection should be suspected in liver transplanted recipients with fever of unknown origin, especially in a recipient who has lived in an endemic area. Brucella also should be considered as a possible diagnosis in patients with pancytopenia.

RESUMEN

OBJECTIVES: The aim of this study was to investigate quantitative cytologic changes in oral mucosal smears collected from kidney transplant patients by modern stereologic methods. METHODS: Smears were obtained from the clinically healthy buccal mucosa and floor of mouth of transplant patients (n = 21) and healthy volunteers (n = 27). Smears from each individual stained by the Papanicolaou method were analyzed using a stereologic method. Nuclear (NV) and cytoplasmic (CV) volumes were evaluated with Stereo Investigator software. RESULTS: CV values were 123,012.71 ± 15,840.96 fL in the floor of the mouth and 133,667.10 ± 26,653.39 fL in the buccal mucosa of the kidney transplant patients. CV values were 133,746.93 ± 14,210.67 fL in the floor of the mouth and 167,797.78 ± 21,007.70 fL in the buccal mucosa of the control group. NV values were 945.68 ± 65.85 fL in the floor of the mouth and 845.15 ± 81.56 fL in the buccal mucosa of the kidney transplant patients and 485.17 ± 18.03 fL in the floor of the mouth and 410.25 ± 52.84 µm(3) in the buccal mucosa of the control group. Significantly higher NV (P = .000) and NV/CV (P = .000) and lower CS (P = .000) values were found in the patient group compared with the control group. CONCLUSION: The findings suggest that there were alterations in oral epithelial cells, detectable by microscopy and cytomorphometry in kidney transplant patients.

RESUMEN

OBJECTIVE: Penetrating colonic injuries are amongst the most discussed intra-abdominal injuries because of the complexity of their management and the severe complications. Penetrating colonic injuries can be managed by either primary repair or diversion. There is a debate over which procedure has to be used under which circumstances. In this retrospective study we analyzed our experience to contribute to the answer. PATIENTS AND METHODS: The records of patients with penetrating colonic injury between January 1995 and December 2006 at the General Surgery Department of Atatürk University School of Medicine, were reviewed retrospectively. RESULTS: One hundred and forty-one patients were included in the study. Ten patients did not need any surgical treatment. Seventy-nine patients (56%) were treated without formation of a stoma and fifty-two patients (36.8%) with formation of a stoma. The overall complication rate was 50.3% (71 patients). The rate of septic complications was 33.3%. CONCLUSION: There is an ongoing debate whether formation of a stoma is indicated in penetrating colonic injury or not. Our clinical experience showed that severe faecal contamination, shock at presentation, and high CIS grades are associated with increased postoperative complications and mortality. Therefore the treatment of penetrating colonic injury in the presence of these risk factors should be stoma formation rather than primary repair.

RESUMEN

BACKGROUND: Liver injury caused by ischemia-reperfusion (I/R) processes is a complication of hepatic resection surgery and transplantation, particularly using grafts from marginal donors. Despite improvements in organ preservation and advances in surgical techniques, I/R injury remains a significant clinical problem. In this study, we investigated whether aprotinin provided protection against the adverse effects of I/R injury in liver tissue. METHODS: Forty rats were randomized into four groups (n = 10): group I: (control group) I/R + no medication; group II: sham-operated group + no medication or I/R; group III: I/R + aprotinin; group IV: I/R + alpha-tocopherol. Malondialdehyde (MDA) was measured in the liver tissue and superoxide dismutase (SOD), catalase (CAT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), as well as lactate dehydrogenase (LDH) in rat serum. RESULTS: Administration of aprotinin and alpha-tocopherol before I/R resulted in significant reductions of MDA levels compared to the I/R alone group (group I; P = .01 and P < .01, respectively). Administration of aprotinin or alpha-tocopherol prior to I/R resulted in significant increases in SOD and CAT levels compared with the I/R group (P < .05 each). Compared to the I/R group, significant decreases in plasma AST, ALT, and LDH levels were observed both in the aprotinin and in the alpha-tocopherol group (P < .05). Histological evaluation revealed the injury grade to be relatively lower among groups III and IV compared to group I. DISCUSSION: In conclusion, rat hepatic structures in aprotinin and alpha-tocopherol administered groups were well protected. Therefore, aprotinin may provide protection against the adverse effects of I/R injury in liver transplantation.

RESUMEN

BACKGROUND: In this study, we aimed to investigate serum total sialic acid (TSA) and soluble intracellular adhesion molecule-1 (sICAM-1) levels in breast cancer patients to find a correlation with the cancer stage. METHODS: The parameters from sera of 61 patients with breast cancer were measured. The concentrations of serum sICAM-1 and TSA were measured in serum samples from 61 patients with breast cancer and 25 healthy control subjects using enzyme-linked immunoassay and thiobarbituric acid method. RESULTS: Mean serum sICAM-1 and TSA levels were significantly higher in the total patient group than in the control group (p < 0.001). Thus, the correlation between TSA and sICAM-1 became more significant in metastatic breast cancer. There were significant positive correlations between TSA and sICAM-1 in stage I+II (r = 0.59, p < 0.05), stage III (r = 0.47, p < 0.05), and stage IV (r = 0.89, p < 0.01), and total patient group (r = 0.56, p < 0.001). CONCLUSION: SerumsICAM-1 and TSA levels were higher in patients with breast cancer, than that of the control group, and also in the metastatic breast cancer group. Significant correlations between serum sICAM-1 and TSA may reflect the similar function of these molecules as adhesion molecules, and their roles in the carcinogenesis of breast cancer as well as metastasis.

RESUMEN

A 63-year-old man who had had a history of rheumatoid arthritis presented with shock and hemoperitoneum, without a history of trauma. An emergency laparatomy revealed hemoperitoneum and splenic rupture with massive bleeding. Splenectomy was performed. Histopathological examination of the spleen revealed amyloid deposition in the wall of the vessels. Rectal biopsy revealed amyloid deposition in mucosa that indicating amyloidosis was systemic. Histochemical studies showed that amyloid was secondary or AA.

RESUMEN

To review clinical, radiological and histopathological findings of adult intussusception and its management, 18 adult patients who had been treated surgically because of intussusception were reviewed. Of the patients, 5 (27.8%) had idiopathic intussusceptions, while the other 13 (72.2%) had a definable intraluminal pathology. The site of the intussusception was more common in the small bowel (83.3%) than the colon (16.7%). Ultrasonography and computed tomography were successful in demonstrating "target lesion" in 80% and 75% respectively. Patients with idiopathic intussusception were treated with simple reduction, while the others underwent segmental resection because of the possibility of malignant tumour. In contrast to intussusception in childhood, intussusception in adults usually has a definable lead point and resection of the involved bowel, rather than simple reduction, is indicated.

RESUMEN

Hepatocellular carcinoma (HCC) has a tendency for fatal spontaneous rupture leading to massive haemorrhage. A 64-year-old man presented with sudden, severe epigastric pain for 6 h. Systolic blood pressure was 80/50 mmHg, and pulse rate was 100/min. The patient's history did not reveal any operation or disease up to date. Contrast enhancement-axial computed tomography (CT) scan showed a tumoral lesion with a necrotic centre measuring 6 x 5 cm within 6th segment of the liver and a fluid collection (haemoperitoneum) at the periphery of the liver. At exploratory laparotomy, the liver was found to be cirrhotic, and an actively bleeding tumour confirmed in 6th segment of the liver. The tumour was resected. Post-operative recovery was unremarkable, and the patient was discharged on the 14th post-operative day. Ruptured HCC should be included in the differential diagnosis of non-traumatic intra-abdominal haemorrhage.
