Fournier's Gangrene: Evaluation of Patient Outcomes Using Clinical Data and Prognostic Biomarkers.

OBJECTIVE: To find out the outcomes of Fournier's gangrene (FG) patients using clinical data and prognostic biomarkers based on the current literature. STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of General Surgery, University of Health Sciences, Gulhane Training and Research Hospital, Ankara, Turkey, from January 2018, to January 2022. METHODOLOGY: Patients who were diagnosed with and treated for FG were included in the study. Patients younger than 18 years of age, those with missing hospital records and postoperative follow-up data, those with benign diseases related to the perianal or anal region, and those with other malignant diseases were excluded from the study. Patients' demographic, clinical, and laboratory data, including the calculated systemic immune-inflammation index (SII) and pan-immune-inflammation values (PIV) were obtained retrospectively from the medical records. Variables were analysed using SPSS statistics software, version 25.0. The value of p <0.05 was considered statistically significant. RESULTS: A total of twenty-four patients, 14 (58.3%) males and 10 (41.7%) females, were included in this study. No statistically significant correlations were found between the calculated indices and patients' clinical outcomes. The length of intensive care unit stay was strongly and positively correlated with age (r = 0.672 and p <0.001), and the length of hospital stay was moderately and inversely correlated with preoperative albumin levels (r = -0.584 and p = 0.003). CONCLUSION: SII and PIV had no statistically significant interactions with FG. KEY WORDS: Fournier's gangrene, Systemic immune-inflammation index, Pan-immune-inflammation value, Colostomy, Albumin.

Evaluation and clinical significance of predictors for strangulation and intestinal resection in emergency anterior abdominal wall hernia surgery.

BACKGROUND: Emergency anterior abdominal wall hernia surgery plays a pivotal role in emergency general surgery practice. In this study, the predictive value of laboratory and imaging findings as well as demographic information and comorbidities of the patients for the recognition of strangulation and intestinal resection was investigated. METHODS: Patients over the age of 18 who were operated consecutively with an indication for emergency anterior abdominal wall hernia surgery between January 2017 and December 2019 in a single tertiary hospital were included in this retrospective cohort study. The patient population was divided into two groups according to the pre-operative findings during the emergency anterior abdominal wall hernia surgery. Group 1 consisted of cases with incarceration but without strangulation, whereas Group 2 consisted of cases with strangulation in addition to incarceration. Moreover, in evaluation for the requirement for intestinal resection, patient Group 2 was divided further into two groups, namely, as Group (1 or 2) a and Group (1 or 2) b, defining the need for intestinal resection. RESULTS: A total of 106 patients who had emergency anterior abdominal wall repair surgery due to incarcerated hernias were included in the study. The evaluation of the indices related to systemic inflammation revealed that lactate dehydrogenase to white blood cell ratio was significantly lower but neutrophil to platelet and neutrophil to albumin ratios were significantly higher in patients with strangulation, showing the significance of those systemic inflammation indices in detecting strangulation (p=0.027, p=0.035 and p=0.030, respectively). Moreover, the analysis of the patients in whom intestinal resection was required (Group 2a vs. 2b) exposed that neutrophil to albumin ratio was significantly higher in the patients with intestinal resection (p=0.036). CONCLUSION: Indices of systemic inflammation such as lactate dehydrogenase to white blood cell ratio, neutrophil to platelet ratio, and particularly neutrophil to albumin ratio may be potentially beneficial to prevent complications and improve clinical outcomes in emergency hernia surgery.

Acute appendicitis over the age of 50: The evaluation of the impact of clinical variables on operative and post-operative outcomes.

BACKGROUND: Studies reported higher mortality and perforation rates, marked increase in delay from symptom onset to hospital admission, significant complication rates, as well as excessive malignancy outcomes on histopathological examinations in patients older than 50 years of age with acute appendicitis. Herein, it was aimed to reveal the clinical, laboratory, and imaging findings that might affect the operative and post-operative findings in a population of patients over the age of 50 who were diagnosed with and operated for acute appendicitis. METHODS: Patients who were older than 50 years of age and operated for the diagnosis acute appendicitis between January 2017 and January 2020 in a single tertiary hospital were included in this retrospective study. Demographic data, comorbidities, laboratory and imaging findings, operative and post-operative results, surgical complications, as well as the histopathological evaluation of the excised materials of all patients were analyzed in detail. RESULTS: A total of 152 patients who were older than 50 years of age and who underwent emergent appendectomy with a median age of 59 were included in the study. It was demonstrated that the development of surgical complications was significantly associated with post-operative hospitalization at the intensive care unit (ICU) and the presence of 2 or more comorbidities preoperatively (p=0.006 and p=0.002, respectively). It was observed that the duration of total hospitalization was longer (p<0.001), pre-operative al-bumin levels were lower (p=0.017), and the rate of hospitalization at ICU during the follow-up period was higher (p=0.006) in patients with surgical complications. Pre-operative white blood cell counts appeared to be significantly increases in patients who had open appendectomy (p=0.047). Moreover, both the duration of pre-operative abdominal pain and pre-operative C-reactive protein levels was found to significantly correlate with the duration of hospitalization (p<0.001 and p<0.001, respectively). CONCLUSION: The management of acute appendicitis in late adulthood was suggested to be challenging both in terms of diagnosis and post-operative processes. Therefore, pre-operative clinical, laboratory, and imaging data obtained from these patients should be carefully and elaborately evaluated.

Cardiac Autoantibody Levels Predict Recurrence Following Cryoballoon-Based Pulmonary Vein Isolation in Paroxysmal Atrial Fibrillation Patients.

INTRODUCTION: Recent evidence has suggested that autoantibodies may play an important role in the development of atrial fibrillation (AF). The predictive value of preprocedural autoantibodies against beta-1 adrenergic receptor (anti-ß1-R) and M2-muscarinic acetylcholine receptor (anti-M2-R) for AF recurrence following cryoballoon-based pulmonary vein isolation (PVI) is still unclear. We aimed to determine the predictive value of preprocedural anti-ß1-R and anti-M2-R levels for AF recurrence. METHODS: Eighty patients (mean age 54.25 ± 7.70 years; 40% female) with paroxysmal AF and preserved left ventricular function who underwent cryoballoon-based PVI were included in the study. Preprocedural anti-M2-R and anti-ß1-R levels were measured with ELISA. RESULTS: At 1-year follow-up after ablation, late AF recurrence was observed in 17 (21.25%) patients. In the Cox regression model, including number of antiarrhythmic drugs, early AF recurrence, anti-ß1-R levels >159.88 ng/mL, anti-M2-R levels >277.65 ng/mL, AF duration, and left atrial volume index, only anti-ß1-R levels >159.88 ng/mL (HR: 4.281, P = 0.039) and anti-M2-R levels >277.65 ng/mL (HR: 4.313, P = 0.030) were found to be independent predictors of late AF recurrence. Anti-ß1-R level >159.88 ng/mL was shown to predict late AF recurrence with a sensitivity of 70.59% and specificity of 90.48%. A cut-off value of 277.65 ng/mL for anti-M2-R level predicted AF recurrence with a sensitivity of 70.59% and specificity of 95.24%. CONCLUSION: Preprocedural serum anti-ß1-R and anti-M2-R levels are independent predictors of late AF recurrence following cryoballoon-based PVI in paroxysmal AF patients. Detection of preprocedural anti-ß1-R and anti-M2-R levels may serve as a novel method for determination of paroxysmal AF patients who may not benefit from cryoballoon-based PVI.

M2-muscarinic acetylcholine receptor autoantibody levels predict left atrial fibrosis severity in paroxysmal lone atrial fibrillation patients undergoing cryoablation.

AIMS: Atrial fibrosis has been found to be associated with recurrent atrial fibrillation (AF) following catheter ablation. Autoantibodies against M2-muscarinic receptors (anti-M2-R) may play a role in the development of AF by inducing left atrial (LA) fibrosis. In this study, we aim to compare anti-M2-R levels between paroxysmal lone AF patients and healthy control subjects and to investigate the relationship between pre-ablation anti-M2-R level, LA fibrosis quantified by delayed enhancement magnetic resonance imaging (DE-MRI), and AF recurrence following cryoablation. METHODS AND RESULTS: Thirty-one patients with paroxysmal lone AF (53.4 ± 8.0 years, 61% male), who underwent cryoballoon-based ablation, along with 31 healthy control subjects were included. Enzyme-linked immunosorbent assay tests to measure serum anti-M2-R levels were performed in both groups and DE-MRI was done to quantify LA fibrosis prior to the ablation in the patients. Anti-M2-R levels were higher in the study population when compared with control subjects [212.4 (103.2-655.5) vs. 73.0 (39.5-299.1) ng/mL, P < 0.001]. Anti-M2-R level predicted moderate-extensive LA fibrosis independent of other measures [odds ratio: 1.26 (95% confidence interval (CI): 1.04-1.53), P = 0.017]. At a mean follow-up of 35.2 ± 3.5 months, nine patients (29.0%) had AF recurrence. In the Cox regression model including pre-ablation anti-M2-R level, LA diameter, LA volume index, and moderate-extensive LA fibrosis, only moderate-extensive LA fibrosis predicted late AF recurrence independent of other measures [hazard ratio: 29.41 (95% CI: 3.52-250.00), P = 0.002]. CONCLUSION: Serum anti-M2-R levels may be associated with the severity of LA fibrosis and may be implicated in the pathophysiology of AF recurrence following cryoablation. Detection of anti-M2-R levels may help select appropriate patients for the procedure.

Elevated M2-muscarinic and ß1-adrenergic receptor autoantibody levels are associated with paroxysmal atrial fibrillation.

BACKGROUND: Pathophysiologic mechanisms underlying lone atrial fibrillation (AF) have not been clearly demonstrated yet. Emerging evidence has indicated that autoimmunity may play a role in the development of AF. Relationship between serum anti-M2-muscarinic receptor autoantibody (anti-M2-R) and anti-ß1-adrenergic receptor autoantibody (anti-ß1-R) levels and lone paroxysmal atrial fibrillation (PAF) has not been investigated. We aimed to compare anti-M2-R and anti-ß1-R levels between lone PAF patients and healthy control subjects. METHODS AND RESULTS: 75 patients with lone PAF (age: 52.80 ± 6.80 years, 53 % male) and 75 healthy control subjects (age: 53.30 ± 6.80 years, 54 % male) were enrolled in the study. Serum anti-M2-R and anti-ß1-R levels were measured by ELISA and compared between two groups. Anti-M2-R [142.30 (77.65-400.00) vs. 69.00 (39.48-299.04) ng/mL; p < 0.001) and anti-ß1-R [102.56 (65.18-348.41) vs. 44.17 (30.89-158.54) ng/mL; p < 0.001] levels were significantly higher in patients with lone PAF compared to healthy controls. Multivariate regression analysis showed that left atrial diameter (OR: 1.471, p < 0.001), hs-CRP(OR: 1.940, p < 0.001), anti-M2-R (OR: 1.158, p < 0.001) and anti-ß1-R (OR: 1.296, p < 0.001) levels were independent predictors for the presence of lone PAF. Using a cut-off level of 101.83 ng/mL, anti-M2-R levels predicted presence of lone PAF with a sensitivity of 94.68 % and specificity of 81.33 %. Anti-ß1-R levels predicted presence of lone PAF with a sensitivity of 92.00 % and specificity of 73.30 %, using a cut-off level of 72.16 ng/mL. CONCLUSION: Our results demonstrated that higher serum anti-M2-R and anti-ß1-R levels are associated with lone PAF. Autoantibodies related to autonomic system may play an important role in the development of lone AF.

Identification of the peripheral blood levels of interleukin-12, interleukin-10, and transforming growth factor-ß in patients with laryngeal squamous cell carcinoma.

BACKGROUND: The aim of this study was to investigate the biology of laryngeal squamous cell carcinoma (SCC) to develop effective novel treatment modalities. METHODS: Serum concentrations of interleukin (IL)-10, IL-12, and transforming growth factor-ß (TGF-ß) were evaluated in 50 patients with laryngeal SCC and 15 controls. Results were compared according to tumor-node-metastasis (TNM) classification criteria. RESULTS: IL-12 and TGF-ß levels were not different between the early- and late-stage patients and controls. Tumor classification or nodal involvement was not associated with IL-12 and TGF-ß levels. Patients with laryngeal SCC had significantly more detectable serum IL-10 levels than those of controls, given that IL-10 could be detected in only 1 early-stage and 9 late-stage patients, but not in the control group (p = .003). IL-10 was increasingly detectable with advanced T classification (p = .009) and nodal involvement (p = .008). CONCLUSIONS: Serum IL-12 or TGF-ß levels were not affected with disease activity and classification; however, serum IL-10 levels were correlated with both parameters.
