Abstract Background Autosomal dominant polycystic kidney disease (ADPKD) is a common hereditary disorder with unclear disease mechanism. Currently, overt hypertension and increased renal volume are the best predictors of renal function. In this study, we assessed the usefulness of selected circulating microRNAs (miRs) to predict disease progress in a cohort with ADPKD. Methods Eighty ADPKD patients (44.6 ± 12.7 years, 40% female, 65% hypertensive) and 50 healthy subjects (HS; 45.4 ± 12.7, 44% female) were enrolled in the study. Serum levels of 384 miRs were determined by Biomark Real Time PCR. Groups were compared using the limma method with multiple-testing correction as proposed by Smyth (corrected p 10% loss of GFR over the following 12 months (cut-off >2.2 AU, sensitivity 83%, specificity 78%, area 0.872 [95% CI: 0.790–0.953, p

Background: Our aim was to investigate the prevalence, size, locations, and shapes of torus palatinus (TP) in end-stage renal disease (ESRD) patients receiving peritoneal dialysis (PD) in order to analyze the relationship between the TP size and duration of PD. Materials and methods: During 2007, 91 ESRD patients receiving PD were studied using dental examinations at our outpatient clinic. Results: The prevalence of TP was 41.7% (n=38). Most cases of TP were < 2 cm in size (81.6%) and spindle-shaped (78.9%). The duration of PD was statistically higher in patients with TP size > 2 cm (6.8±3.6 years) than patients with TP size of < 2 cm (3.5±2.6 years). Conclusions: The higher prevalence of TP and different TP shape (spindle) in comparison with our previous study and the significant relationship between duration of PD and TP size might be due to an underlying disorder, such as renal osteodystrophy.

PURPOSE: To analyze the effect of maintenance hemodialysis on left ventricular diastolic function in patients with end-stage renal disease. METHODS: Study population consisted of 42 patients with end-stage renal disease. Before an arteriovenous fistula was surgically created, the patients were evaluated by conventional and Doppler echocardiography and Doppler tissue imaging. Then, the patients undergoing hemodialysis treatment when the arteriovenous fistula was compleated. After the first hemodialysis session (mean 76.14 ± 11.37 days) the second echocardiographic evaluations were performed. RESULTS: Mean age was 58 ± 13 years and 21 (%50) of the patients were female. After maintenance hemodialysis treatment; peak early (E) and peak late (A) diastolic mitral inflow velocities and E/A ratio were not significantly change however the deceleration time of E wave and left atrial diameter were significantly increased. Also there was no change in the early (Em) and late (Am) diastolic myocardial velocities and Em/Am ratios of lateral and septal walls of left ventricular. E/Em ratio was decreased insignificantly. Pulmonary vein velocities and right ventricular functions are remained almost unchanged after hemodialysis treatment. DISCUSSION: The acute and long-term effect of hemodialysis on left ventricular diastolic function is unclearly. Patients with end-stage renal disease treatment with hemodialysis via arteriovenous fistula experience a variety of hemodynamic and metabolic abnormalities that predispose to alterations in left and right ventricular functions. The present study showed that left ventricular diastolic function except left atrial diameter and right ventricular functions were not significantly change, however left ventricular systolic functions were impaired after maintenance hemodialysis treatment in patients with end-stage renal disease. CONCLUSION: It has been suggested that echocardiographic parameters are useful markers for evaluation of left ventricular and right ventricular functions in patients with end-stage renal disease. However, in patients with endstage renal disease treated with hemodialysis, repeated assessment of echocardiographic examinations to observe serial changes in left and right ventricular functions are not yet well established. In this study, we showed that acute changes of volume status and electrolytes and autonomic regulation by hemodialysis session did not affect left ventricular diastolic and right ventricular functions in a relatively long term.

Ethylene glycol (EG) may be consumed accidentally or intentionally, usually in the form of antifreeze products or as an ethanol substitute. EG is metabolized to toxic metabolites. These metabolites cause metabolic acidosis with increased anion gap, renal failure, oxaluria, damage to the central nervous system and cranial nerves, and cardiovascular instability. Early initiation of treatment can reduce the mortality and morbidity but different clinical presentations can cause delayed diagnosis and poor prognosis. Herein, we report a case with the atypical presentation of facial paralysis, hematuria, and kidney failure due to EG poisoning which progressed to end stage renal failure and permanent right peripheral facial nerve palsy.

Aim. Carpal tunnel syndrome (CTS) is one of the frequent problems of the patients who underwent hemodialysis (HD). The role of venous hypertension due to arteriovenous fistula (AVF) has not been clarified completely; therefore, we aimed to investigate the role of venous hypertension due to AVF in hemodialysis patients who had CTS. Patients and Methods. We included 12 patients who had been receiving HD treatment for less than 8 years and the newly diagnosed CTS patients with the same arm of AVF. All patients were diagnosed clinically and the results were confirmed by both nerve conduction studies and electromyography. Open carpal tunnel release surgery was performed on all of them. Venous pressure was measured in all patients before and after two weeks of surgery. Results. There were significant differences before and after the surgery with regard to pressures (). After the surgery, all carpal ligament specimens of the patients were not stained with Congo red for the presence of amyloid deposition. Conclusion. Increased venous pressure on the same arm with AVF could be responsible for CTS in hemodialysis patients. Carpal tunnel release surgery is the main treatment of this disease by reducing the compression on the nerve.

Abstract Introduction Bronchobiliary fistula is an uncommon complication secondary to hepatobiliary surgery. Bilioptysis is a pathognomic finding for bronchobiliary fistulas. Diagnosis may be easily established in the light of clinical history, which can be aided by imaging studies to pinpoint the exact location. Some diagnostic procedures such as endoscopic retrograde cholangiopancreatectomy are also useful for treatment. Case presentation We present three Turkish patients with bronchobiliary fistula secondary to previous hepatic surgery due to hydatid cyst in two, a 19-year-old and a 47-year-old man, and iatrogenic trauma of the common bile duct by endoscopy in a 35-year-old man. All of the patients were successfully treated by minimally invasive methods including percutaneous drainage and endoscopic retrograde cholangiopancreatography. Conclusion We suggest that bronchobiliary fistula could be managed through conservative treatment methods which do not require in-hospital follow-up, particularly in uncomplicated cases. Otherwise, surgical management can be unavoidable.

Abstract Peri-hepatic packing procedure, which is the basic damage control technique for the treatment of hepatic hemorrhage, is one of the cornerstones of the surgical strategy for abdominal trauma. The purpose of this study was to evaluate the efficacy of the perihepatic packing procedure by comparing the outcomes of appropriately and inappropriately performed interventions. Trauma patients with liver injury were retrospectively evaluated. The patients who had undergone adequate packing were classified as Group A, and the patients who had undergone inappropriate packing, as Group B. Over a five-year period, nineteen patients underwent perihepatic packing. Thirteen of these patients were referred by other hospitals. Of 13 patients, 9 with inappropriate packing procedure due to insertion of intraabdominal drainage catheter (n=4) and underpacking (n=5) were evaluated in Group B, and the others (n=10) with adequate packing were assessed in Group A. Mean 3 units of blood were transfused in Group A and unpacking procedure was performed in the 24th hour. Only 3 (30%) patients required segment resection with homeostasis, and the mortality rate was 20% (2/10 patients). In Group B, 4 patients required repacking in the first 6 hrs. Mean 8 units of blood were transfused until unpacking procedure. The mortality rate was 44% (4/9 patients). The length of intensive care unit stay and requirement of blood transfusion were statistically significantly lower in Group A (p < 0.05). The mortality rate of this group was also lower. However, the difference between the groups for mortality rates was not statistically significant. This study emphasizes that efficacy of the procedure is one of the determinants that affects the results, and inadequate or inappropriate packing may easily result in poor outcome.

Abstract There are several surgical complications which can occur following simultaneous pancreas-kidney transplantation (SPKT). Although intestinal obstruction is known to be a common complication after any type of abdominal surgery, the occurrence of small bowel volvulus, which is one of the rare causes of intestinal obstruction, following SPKT has not been published before. A 24-year-old woman suffering from type I diabetes mellitus with complications of nephropathy resulting in end stage renal disease (ESRD), neuropathy and retinopathy underwent SPKT. On the postoperative month 5, she was brought to the emergency service due to abdominal distention with mild abdominal pain. After laboratory research and diagnostic radiological tests had been carried out, she underwent exploratory laparotomy to determine the pathology for acute abdominal symptoms. Intra-operative observation revealed the presence of an almost totally ischemic small bowel which had occurred due to clockwise rotation of the mesentery. Initially, simple derotation was performed to avoid intestinal resection because of her risky condition, particularly for short bowel syndrome, and subsequent intestinal response was favorable. Thus, surgical treatment was successfully employed to solve the problem without any resection procedure. The patient's postoperative follow-up was uneventful and she was discharged from hospital on postoperative day 7. According to our clinical viewpoint, this study emphasizes that if there is even just a suspicion of acute abdominal problem in a patient with SPKT, surgical intervention should be promptly performed to avoid any irreversible result and to achieve a positive outcome.

Abstract Background Superior mesenteric injury is a rare entity but when it occurs, short bowel syndrome is one of the uninvited results of the emergency surgical procedures. Case presentation We present a 19-year-old boy with blunt abdominal trauma which caused serious mesenteric injury. Because ultrasound revealed free intraabdominal fluid, he underwent emergency laparotomy. Adequate vascularization of approximately 20 cm of proximal jejunal segment and approximately 20 cm of terminal ileum was observed. Nevertheless, the mesentery of the rest of the small intestine segments was ruptured completely. We performed an end-to-end anastomosis between a distal branch of the superior mesenteric artery in the mesentery of the ileal segment and a branch of the superior mesenteric artery using separate sutures of 7.0 monofilament polypropylene. The patient's gastrointestinal passage returned to normal on the postoperative day 2. He recovered without any complication and was discharged from hospital on the postoperative day seven. Discussion In this case report, we emphasize the importance of preservation of injured mesenteric artery due to abdominal trauma which could have resulted in short bowel syndrome.

Abstract Background Currently, portal hypertension is still big problem for the patients with serious liver diseases. Variceal bleeding is one of the most important complications of portal hypertension. In case of failure of endoscopic and combined medical treatments, surgical decompressive shunts are required. We emphasized an alternative splenorenal shunt procedure using adrenal vein as a conduit. Case presentation A 26-year-old male suffered from recurrent variceal bleeding was considered for surgical therapy. Although we planned to perform a distal splenorenal shunt procedure, it was observed to be difficult. Therefore left adrenal vein was used as a conduit between left renal vein and splenic vein after splenic artery was ligated. He did well and was discharged from the hospital on the postoperative day 6. In the follow up period for nine months, endoscopic and ultrasonographic examinations were normal. Conclusion We concluded that, in case of failure to perform distal splenorenal shunt due to technical problems, alternative porto-systemic shunt procedure using the adrenal vein as a vascular conduit can be safely employed.

Aim: Chronic venous insufficiency (CVI) is a condition that results from obstruction, valve insufficiency, dysfunction of calf muscle pump, or their combinations. This study analyzed the risk factors and demographic characteristics of CVI in nurses in Türkiye. Additionally, it seeks to identify the total number of patients treated at medical centers in 2022 and assess the prevalence of CVI. Material and Methods: This multicenter, descriptive, and cross-sectional study was conducted with the participation of nurses working in 18 centers. Nurses completed a questionnaire that included their demographic information and venous insufficiency risk factors, and the Venous Insufficiency Epidemiological and Economic Study-Quality of Life Questionnaire. Researchers also completed the Standard CEAP Form Section C. The cases were divided into 2 groups: CVI (-) group (n=776, 43.5%) and CVI (+) group (n=1010, 56.5%). Results: A total of 1786 nurses participated in this study. Older age (>30-39 years), female gender, ≥2 pregnancies, ≥2 childbirths, years in the profession (>5-15 years), family history, and night cramps were identified as risk factors for CVI (p<0.001). No significant difference was found between smoking, body mass index, and CVI status (p>0.05). Hypertension, diabetes, and a history of deep vein thrombosis were the most common coexisting diseases. With a one-unit increase in age, risk of CVI increased 1.1-fold, family history of VV increased CVI risk 1.9-fold and presence of nocturnal night cramps increased risk of CVI 2.6-fold. The prevalence of CVI in 2022 was found to be 22.66% in this study. Conclusion: Older age, female gender, ≥2 pregnancies, ≥2 childbirths, years in the profession, family history, and night cramps are identified as risk factors for CVI in nurses. Common comorbid diseases include hypertension, diabetes, and a history of DVT. Pregnancy, particularly with multiple occurrences, stands out as a critical period for CVI. Reported symptoms in CVI (+) nurses include leg pain, swelling, heaviness, restless legs, and throbbing. Nurses demonstrate a higher incidence of CVI compared to other professions, highlighting an occupational risk. These findings stress the importance of preventive measures for nurses.

Aim: Our study aims to share the reintervention results of patients who were operated with the diagnosis of Type A aortic dissection and to examine the factors that cause reintervention. Material and Methods: In our single-center retrospective study, 244 patients who underwent surgery due to Type A aortic dissection between November 2010 and June 2021 were included. Results for patients who underwent reintervention and factors which caused reintervention were compared with demographic data, preoperative, intraoperative and postoperative variables. Results: A total of 142 patients were included in the study and 15.5% of them underwent reintervention. Reoperation was performed in 8 (36.4%) of 22 patients who underwent reintervention, while thoracic aortic endovascular repair was performed in 14 (63.6%) patients. Post-procedure mortality was observed in 5 (22.7%) of the patients who underwent reintervention. The mean age of the patients who underwent reintervention was 46.6±13.2 and there was a statistically significant (p<0.05) difference between the groups (p: 0.026). Results that were significant for reintervention were multivariate analysis with cox regression and it was shown that the persistence of postoperative hypertension with total arch surgery was a risk factor for reintervention (p: 0.03, p: 0.008). Conclusion: Type A aortic dissection is not considered to be completely cured after the first operation. It is necessary to evaluate the patients in terms of reintervention with close follow-up. We propose that patients who underwent total arch surgery during the first operation and hypertension in the postoperative period are risk factors for reintervention. [ABSTRACT FROM AUTHOR]

Aim: Technological developments on endovascular stents have increased the percutaneous repair of abdominal aortic aneurysm(AAAs). Open repair of abdominal aneurysm remains as the first option for treatment of aneurysm with compromising necks that need suprarenal aortic clamping(SAC). Open surgical repair with suprarenal aortic clamping may be associated with renal ischemia that may lead into renal injury. Our study focused on our clinical experience on the use of custodiol solution for renal protection during open repair of abdominal aortic aneurysm with suprarenal aortic clamping. Material and Methods: Our study consisted of 25 patients who underwent open repair for abdominal aortic aneurysm with suprarenal aortic clamping. During the repair, cold custodiol solution was used for renal protection in all patients. Outcomes included postoperative renal functions, mortality, hospital stay, need of postoperative dialysis and readmission due to renal injury. Results: 2 (8%) of our patients died, 2 patients (8%) experienced acute renal injury, hemodialysis was required in 8 patients (32%). There were 3 cases of morbidity, which included ileus in one patient, pneumonia in one patient and wound infection in one patient. Graft interposition was performed in one patient (4%) while aortobifemoral bypass was performed in 24 patients (96%). Conclusion: In our clinical experience, cold custadiol solution has shown to be safe as a renal protective solution during suprarenal aortic clamping in open repair of abdominal aortic aneurysm with well-preserved perioperative renal functions.

Aim: The gold standard repair of thoracoabdominal aortic aneurysm (TAAA) is still open surgery. However, few cardiovascular centers are experienced in TAAA repair. The aim of this study was to examine the methods and four-year outcomes of the open TAAA repair program initiated by a single surgical team. Material and Methods: In this retrospective cohort, patients who were operated for TAAA between August 2018 and March 2022 were collected. Patients treated with the endovascular approach were excluded. After exclusion, 19 patients were included in our analysis. As postoperative outcomes, in-hospital mortality, spinal cord deficit, major neurologic complications, need for dialysis, and visceral ischemia were collected. Results: Crawford extent II TAAA repair was performed in 10 (52.6%) patients, Crawford extent III in 5 (26.3%) patients, and Crawford extent IV in 4 (21.1%) patients. In hospital mortality occurred in 6 (31.6%) patients. The causes of mortality were perioperative myocardial infarction in 2 (10.5%) patients, visceral ischemia in 1 (5.3%) patient, multisystem organ failure in 3 (15.8%) patients. The highest mortality rate (50.0%) occurred in Crawford extent II repair. Spinal cord deficit developed in 2 (10.5%) patients. Conclusion: Thoracoabdominal aortic aneurysm surgery is associated with high mortality rates. Open thoracoabdominal aortic aneurysm repair programs in tertiary vascular centers should be supported, to improve the surgical results of thoracoabdominal aortic aneurysm repair.
