ANTEGRAD URETERAL STENTING; INDICATIONS - METHODS - COMPLICATIONS AND RADIOLOGICAL APPROACH TO  COMPLICATIONS

Abstract:

Objectives

The aim of this study is to evaluate the indications, success rate, complications, technical success enhancing method, methods of antegrad ureteral stenting and the radiological management of complications due to retrograde and antegrade ureteral stenting in the treatment of ureteral obstructions and ureteral leaks caused by malignant and benign etiologies.

Materials and Methods

In this retrospective study, fluoroscopy and US-guided antegrade ureteral stenting procedures between January 2016 and December 2018 were examined. The study included 110 antegrade ureteral stenting and percutaneous nephrostomy in a total of 78 patients with 25 female patients (32.05 %), a mean age of 65.87 (20-90) and 53 male patients (67.94%) with a mean age of 68.73 (30-90).  Demographic data, antegrade ureteral stenting indications, procedure results and complications were evaluated for each patient.

Results

Antegrade ureteral stenting is a good alternative for patients with retrograde ureteral stent placement and already with percutaneous nephrostomy catheters. It has a high technical success rate and low complication risk. The use of the equipment used in other radiological procedures in antegrade ureteral stenting increases the technical success. Malposition,  perforation, hemorrhage, urinoma, abscess complications such as retrograde or antegrade ureteral stenting can be managed by radiological methods.

Aim: Gallbladder cancer is an uncommon, but aggressive tumor. Its prognosis is poor and the most cases are incidentally detected in histopathological examinations of cholecystectomies due to benign diseases. With the era of laparoscopic cholecystectomy, the number of cases detected in early stage is increasing. In this study, we aimed to evaluate the rate of cancer encountered and the distribution of non-cancer diagnoses in cholecystectomy materials sent to our department, together with the literature findings.

Materials and Methods: The results of the cholecystectomy materials sent to the pathology laboratory and examined routinely in 2016-2017 were retrospectively evaluated by forming diagnostic groups. Clinical preliminary diagnoses, demographic informations (age, sex), and pathology reports of the patients were reviewed.

Results: We included a total of 1000 cholecystectomy materials into the study. Two of the 7 patients who presented with malignancy were incidentally diagnosed and underwent laparoscopic cholecystectomy with the preliminary diagnosis of cholelithiasis, with the primary focus was gallbladder in one patient, and the other was compatible with colonic adenocarcinoma infiltration. Preoperative and / or perioperative malignancy was detected in the remaining 5 patients. A large proportion (> 90%) of the other cases had chronic or chronic active cholecystitis and low rate of acute cholecystitis included gastric heterotopia found in 2 (0.2%), tubular adenoma in 1 (0.1%), tubulovillous adenoma in 1 (0.1%), adenomyoma / adenomyomatosis in 4 (0.4%), polyp in 6 (0,6%) and dysplasia (Biliary intraepithelial neoplasia, BilIN) in 5 (0.5%) patients.

 The most seen pathophysiological mechanism of acute coronary syndrome is intracoronary thrombus after plaque rupture. ST elevation myocardial infarction is caused by occlusion of coronary arteries. The treatment is based on fibrinolytic treatment or coronary intervention. If there is massive thrombus burden in coronary artery we can use manuel thrombus aspiration. In our case, we treated patient, who referred to hospital with ST elevation myocardial infarction, by manual thrombus aspiration without using stent.  

The presence of cardiac disease in pregnancy is still one of the most important reason of maternal mortality. The possibility of acute coronary syndrome increases in pregnancy. Birth with caesarean section provides proper hemodynamic monitoring and management in parturients with cardiac disease. However the ideal anesthetic to be applied to parturient with cardiac disease is controversial. Although regional anesthesia is usually preferred method, general anesthesia may be applied in some special cases. Invasive monitoring reduces mortality and morbidity in cardiac patients undergoing general anesthesia. Opioid use reduces the stress response to surgery and intubation. If the use of opioid is required before birth, remifentanil is the ideal agent because of its rapid onset of action and metabolism. In this case, we aimed to present our general anesthesia experience on a parturient with high cardiac risk where regional anesthesia is contraindicated because of the use of anticoagulation.

Objective: Most of the renal neoplasms are the epithelial and malign ones. The renal cell carcinoma (RCC), which is the most frequently seen malign renal tumor, consists of 2-4% of all the malign tumors seen among adult individuals and 80-90% of all the malign renal tumors. RCCs peak at sixties and seventies and its prevalence among males is two folds of its prevalence among females. RCCs have bad prognosis. The recurrence is seen in 40% of the cases, and the metastasis despite the early diagnosis was detected in 50% of cases. In present study, it was aimed to distribution of renal tumors in our hospital, discuss the prognostic factors such as the, pathological stage, nuclear grade and tumor diameter accompanied by literature information.

Patients and Method: By retrospectively scanning the records of Pathology Department of Medical Faculty, Fırat University, for the period between 1988 and 2009, 140 renal tumor cases were determined and the previous diagnoses, histological degrees, pathological stages of these cases were evaluated and the final diagnoses were taken as base in the present study. In pathologically staging (pT) of RCCs, TNM classification was used, whereas Fuhrman nuclear grading (FNG) was used in nuclear grading procedure. The patients were divided into different groups based on their genders and ages. The statistical analyses were performed in SPSS-12.0 software by using Chi-Square and Correlation tests.

Results: When compared to the literature in terms of the mean age, the present study involves relatively young population (mean age 57), and the majority was male (male/ female:1.1). The distributions of renal tumours, malign and benign subtypes, and RCC subtypes show similarities with the general literature. When examining the RCCs statistically, no significant relationship was found between diagnosis and age, and between nuclear grade and tumor diameter (p>0.05). In the present study, the RCCs with largest diameter were papillary type (9,78cm) ones, whereas the RCCs with lowest diameter values were classic type. A statistically significant relationship was observed between the benign, borderline and malign tumor diagnoses and diameters (p= 0.023). It was determined that approximately one-four of RCC cases were in highly pathological stage (21,6%, pT3a-3b). A direct proportional and statistically significant relationship was found between nuclear grade and diameter (p=0,002).

Conclusion: RCCs have poor prognosis and their frequency is increasing. Pathological stage, nuclear grade and diameter are the leading factors affecting the prognosis. As in our study, in retrospective studies involving old ages and not enough sampling, tumor diameter may be used as an alternative prognostic factor for pathological staging in tumors with a stage above pT2.

\r\n Objective: Early diagnosis of cutaneous squamous cell carcinomas (CSCC) is the most important factor affecting prognosis and most patients have a good prognosis. Some patients defined as high-risk group have high rates of regional recurrence and distant metastasis, and follow an aggressive course. In addition, recently numerous studies have being performed for determining the importance of sentinel lymph node sampling, and sentinel lymph node (SLN) positivity has been associated with a poor prognosis. In this study, we aimed to determine prognostic importance of SLN outcomes in patients with high-risk patients diagnosed with CSCC.

\r\n Patients & Methods: A total of 29 patients who underwent excisional operation in various body regions with the diagnosis of CSCC between 2009 and 2017, with available complete clinical and pathologic data were included in the study. At least 9-month clinical follow-up results, high risk factors and sentinel lymph node biopsy outcomes of the patients were recorded and analyzed. Patients with at least one of the American Joint Committee on Cancer (AJCC) criteria were considered as high-risk group.

\r\n Results: Twenty-five of the 29 CSCC patients were in the high-risk group. SLN positivity rate was 12% (n: 3/25) in the high-risk CSCC patients, all patients in the low-risk group had negative SLNs. All patients with SLN positive underwent local complementary lymphadenectomy, and all of these patients were re-operated due to recurrence. The rate of recurrence was found as 100% (n= 3/3) in high-risk CSCC patients with positive SLN, and 18% (n= 4/22) in high-risk CSCC patients with negative SLN. High recurrence rates (41.6%) and SLN positivity were observed in patients with hand-foot localizations.

\r\n Conclusion: High rates of local recurrence may be seen during progression of the disease in SLN positive patients. Hand-foot localization of CSCCs can be considered as a high risk factor regardless of a tumor diameter should be above 0.6 cm.

Objective: Mucormycosis is an infrequent opportunistic fungal infection which may cause an aggressive and invasive soft tissue necrosis. It is usually developed in patients with immune system deficiency, and rarely seen in immunocompetant patients.  We report prognosis and treatment of the immunocompetant patients that developed facial cutaneous mucormycosis after short term corticosteroid therapy.

Material and Method: The patients who were admitted to Manisa Celal Bayar University Hospital after multitrauma and given short term corticosteroids due to cranial and spinal injuries and became immuncompromised and diagnosed as facial cutaneous mucormycosis between 2016 and 2018 were included in the study. Prognosis, medical and surgical treatment outcomes of therapy is reported.

Results: One patient with malar and maxillary involvement was treated with medical therapy and serial debridements and infection was cured. Reconstruction with free flaps were done, acceptable functional and aesthetic results were achieved. Two patients had adequate therapy and reconstructed with local flaps.   One patient was not operated due to recurrent fungal osteomyelitis and intracranial inflammatory findings, and regression in MRI was seen.

Conclusion: Mucormycosis should be kept in mind in contaminated wound infections in patients who have been treated with corticosteroids even for a short time after multitrauma. Rapid, repetitive and aggressive debridemants should be performed and reconstruction should be planned after cure of the fungi.

 Moyamoya disease is an entity, which is caused by obstruction or stenosis in the area between the internal carotid artery, and anterior and middle cerebral arteries, identified angiographically, and does not have an exactly known etiology. The most frequent symptoms of onset are hemorrhage in adults and ischemia in children. In this paper, we present a case of Moyamoya disease which was diagnosed with a 21 year old male patient who was admitted to our emergency department with headache, nausea vomiting and left hemiparasi complaints and whose radiological findings showed right basal ganglia hemorrhage.

Abstract

Aim: Since clinical and prognostic heterogeneity is observed in diffuse large B-cell lymphoma (‎DLBCL) patients, it is vital to determine its prognostic and predictive factors. The frequency of these factors varies geographically and ethnically. We aimed to reevaluate and discuss the prognostic and predictive ‎factors of DLBCL patients who have been treated with R-CHOP in our ‎center based on the WHO 2017 revised 4^th edition.‎ We also investigated the incidence of EBV in DLBCL-NOS.

Patients and Methods: Patients with DLBCL-NOS diagnosed previously in our hospital between 2007-2017 and treated with ‎R-CHOP were included in the study. We evaluated the expressions of CD10, CD5, CD30, BCL-2, BCL-6, MUM-1, MYC, LMP-1, EBNA-2, Ki-67, and p53, by immunohistochemistry, and EBV encoded RNA by in situ hybridization in 104 cases of DLBCL-NOS. The Revised International Prognostic Index (R-IPI) score and the overall survival time ‎was ‎calculated.

Results: The study included 56 men (53.8%) and 48 women (46.2%). The median age was 64.5 years. In 59.6% of the patients, the disease had a nodal beginning, whereas in 40.4% of the patients it had an ‎extranodal presentation. High ‎stage (III-IV) was present in 26.5% of the GCB subtype and 43.6% of non-GCB subtype (p=0.049). A high ‎R-IPI score was observed in 40% of GCB subtype and 54.5% of non-GCB subtype (p=0.028). Survival was significantly lower in the non-GCB subtype (log-rank test p=0.003).‎ The EBV frequency was about 3% as it is reported in Western populations. The frequency of DEL status was 8.7%, indicating that it was associated with inferior survival (p=0.045). De novo CD5⁺ DLBCL ratio as 13% and it was also associated with inferior survival (p=0.013).  We also found CD30⁺ DLBCL ratio as 11.5%, but we could not establish a significant relationship with prognosis.

Conclusion: DLBCL-NOS requires detailed subtyping and elaboration of prognostic factors. ‎The frequency of DEL status and De novo CD5⁺ DLBCL indicated that it was associated with inferior survival. However, we could not establish ‎a meaningful relationship of CD30⁺ DLBCL with prognosis.‎ Three EBV positive cases were identified and two of them were classified as ‘EBV positive large B cell lymphoma’ according to the WHO 2017 revised 4^th edition.

Introduction: Circulating stem cells (CSCs) are released from bone marrow in to the circulation after myocardial injury to improve tissue repair. Radiofrequency ablation (RFA) of cardiac arrhythmias, particularly for atrial fibrillation, has been shown to trigger the release of CSCs through inflammatory mediators. We aimed to investigate whether CSCs are increased in the circulation following non-extensive ablation procedures such as slow pathway or accessory pathway ablations.

Methods: Twenty-six patients [13 females, 54 (18-74) years old] who underwent slow pathway ablation for atrioventricular nodal reentrant tachycardia (n=18) and accessory pathway ablation for atrioventricular reentrant tachycardia (n=8) were included. Peripheral blood CD34+ cell count and multiple serologic markers [troponin I (Tn-I), C-reactive protein (CRP), interleukin-6 (IL-6), stromal cell derived factor (SDF) 1 alpha] were evaluated before the ablation procedure and 7 and 30 days after the procedure.

Results: The CD34+ cell count was significantly increased on the 7^th day after the procedure when compared to baseline [33 (15-133) vs. 22,5 (5-79) cells per microliter respectively, P<0.001]. The CD34+ cell count was similar to baseline on the 30^th day following the procedure. Levels of Tn-I, CRP, IL-6 and SDF1-α did not change significantly following ablation. The amount of energy applied during RFA (watts) was significantly correlated with the 30^th day CD34+ cell count (r: 0.460; p= 0.018).

Conclusions: Peripheral blood CSCs are increased after slow pathway or accessory pathway ablations which are less extensive ablations compared to atrial fibrillation ablation. The levels return to baseline by the 30^th day following the procedure. The increase in CSCs was positively correlated with the amount of energy delivered during the procedure.

Abstract

INTRODUCTION

Acute mesenteric ischemia (AMI) is an acute abdominal disease which is age-related with possible bad prognosis; and while its morbidity and mortality rate is 10% in early diagnosis and treatment it may progress with 100% mortality when diagnosis and treatment are delayed.The aim of this study was to unearth the efficiency of neutrophil-to-lymphocyte ratio (NLR) which has recently been started to be utilized in the prediction of AMI prognosis and used as a prognostic factor in many diseases.

MATERIALS and METHODS:

The data of a total of 111 patients, who had undergone surgical procedures and diagnosed with mesenteric ischemia intraoperatively at Necmettin Erbakan University Meram Medical School’s General Surgery Clinic between 2005 and 2013 and whose diagnoses had later on been confirmed pathologically, were retrospectively evaluated within the scope of the study.

The demographic data of all patients (age, sex) were recorded. The hemogram results of the patients, analyzed with peripheral blood, were reviewed for preoperative evaluation. The surgical procedure performed, the part and length of the resected bowel based on pathology results, the duration of hospitalization, survey, presence of comorbidity, white blood cell count, creatinine values, and NLR of the patients were determined. The data were statistically analyzed.

RESULTS:

The patients who did not survive had a mean NLR of 24.77 ±10.38, while the same ratio was found to be 17.6±10.65 for survivors. The NLO value was found to be high in cases with mortality.

CONCLUSION:

AMI still proves to have high mortality in spite of the developments in imaging techniques and laboratory analyses. There is no specific laboratory analysis for early diagnosis. High preoperative NLR in patients suspected to have AMI may indicate bad prognosis.
