Prevalence of oral infections in chronic kidney disease patients: A cross-sectional study.

OBJECTIVES: The purpose of this investigation was to analyze the prevalence of apical periodontitis (AP) and periodontal disease (periodontitis) (PD) in Chronic kidney disease (CKD) patients in relation to their treatment phase. SUBJECTS AND METHODS: In this cross-sectional study, 188 patients with CKD were divided into two groups: patients without dialysis (WD group, n = 53) and patients on dialysis (DP group, n = 135). Panoramic radiographs were used to diagnose AP. The presence of periodontal disease was evaluated radiographically assessing alveolar bone loss. Student's t-test, chi-squared test, and logistic regression analysis were used to determine the significance of differences between groups. RESULTS: In the WD group, 55% of patients had at least one tooth with AP, whereas in the DP group 67% had at least one tooth with AP (OR = 2.11; 95% CI = 1.09-4.08; p < 0.05). PD was more prevalent in the DP group (78%) than in the WD group (36%) (OR = 6.26; CI 95% = 3.13-12.52; p < 0.01). CONCLUSIONS: Oral infections are more prevalent in the advanced stages of CKD. The treatment of PD and AP should be incorporated in the treatment planning of patients with CKD.

Efficacy and Safety of Intraoperative Hyperthermic Intraperitoneal Chemotherapy for Locally Advanced Colon Cancer: A Phase 3 Randomized Clinical Trial.

Importance: Peritoneal metastasis in patients with locally advanced colon cancer (T4 stage) is estimated to recur at a rate of approximately 25% at 3 years from surgical resection and is associated with poor prognosis. There is controversy regarding the clinical benefit of prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC) in these patients. Objective: To assess the efficacy and safety of intraoperative HIPEC in patients with locally advanced colon cancer. Design, Setting, and Participants: This open-label, phase 3 randomized clinical trial was conducted in 17 Spanish centers from November 15, 2015, to March 9, 2021. Enrolled patients were aged 18 to 75 years with locally advanced primary colon cancer diagnosed preoperatively (cT4N02M0). Interventions: Patients were randomly assigned 1:1 to receive cytoreduction plus HIPEC with mitomycin C (30 mg/m2 over 60 minutes; investigational group) or cytoreduction alone (comparator group), both followed by systemic adjuvant chemotherapy. Randomization of the intention-to-treat population was done via a web-based system, with stratification by treatment center and sex. Main Outcomes and Measures: The primary outcome was 3-year locoregional control (LC) rate, defined as the proportion of patients without peritoneal disease recurrence analyzed by intention to treat. Secondary end points were disease-free survival, overall survival, morbidity, and rate of toxic effects. Results: A total of 184 patients were recruited and randomized (investigational group, n = 89; comparator group, n = 95). The mean (SD) age was 61.5 (9.2) years, and 111 (60.3%) were male. Median duration of follow-up was 36 months (IQR, 27-36 months). Demographic and clinical characteristics were similar between groups. The 3-year LC rate was higher in the investigational group (97.6%) than in the comparator group (87.6%) (log-rank P = .03; hazard ratio [HR], 0.21; 95% CI, 0.05-0.95). No differences were observed in disease-free survival (investigational, 81.2%; comparator, 78.0%; log-rank P = .22; HR, 0.71; 95% CI, 0.41-1.22) or overall survival (investigational, 91.7%; comparator, 92.9%; log-rank P = .68; HR, 0.79; 95% CI, 0.26-2.37). The definitive subgroup with pT4 disease showed a pronounced benefit in 3-year LC rate after investigational treatment (investigational: 98.3%; comparator: 82.1%; log-rank P = .003; HR, 0.09; 95% CI, 0.01-0.70). No differences in morbidity or toxic effects between groups were observed. Conclusions and Relevance: In this randomized clinical trial, the addition of HIPEC to complete surgical resection for locally advanced colon cancer improved the 3-year LC rate compared with surgery alone. This approach should be considered for patients with locally advanced colorectal cancer. Trial Registration: ClinicalTrials.gov Identifier: NCT02614534.

Periapical and endodontic status of patients with inflammatory bowel disease: Age- and sex-matched case-control study.

AIM: Crohn's disease (CD) and ulcerative colitis (UC) are two chronic recurrent inflammatory processes of the gastrointestinal tract, grouped under the name inflammatory bowel disease (IBD), causing clinical episodes of intestinal inflammation. The aim of this study was to investigate the possible association between IBD and the prevalence of apical periodontitis (AP) and root canal treatment. METHODOLOGY: A case-control study design matched to age and sex was used. The study group (SG) included 28 patients with IBD (13 with CD, 15 with UC). Another 28 healthy subjects, without IBD and age- and sex-matched, were included in the control group (CG). Radiographic records were analysed and AP was diagnosed as radiolucent periapical lesions (RPLs), using the periapical index score. Student's t-test, χ2 test and multivariate logistic regression were used in the statistical analysis. RESULTS: In the CG, only 17 subjects (61%) had at least one tooth with AP, whilst in the SG group they were 23 patients (82%; OR = 2.98; 95% CI = 0.87-10.87; p = .08). The number of subjects with one or more root filled teeth (RFT) in the CG was 14 (50%), whilst in the SG they were 22 (79%; OR = 3.67; 95% CI = 1.14-11.79; p = .026). At least one RFT with AP was evident in three subjects (10.7%) in the CG, whilst in the SG 15 patients (53.6%) showed RFT with AP (OR = 9.60; 95% CI = 2.35-39.35; p = .001). In the multivariate logistic regression analysis, only endodontic status was found to be associated with IBD (OR = 1.86; 95% CI = 1.24-2.80; p = .003). CONCLUSION: IBD, UC and Crohn's disease are associated with higher prevalence of RFT and higher percentage of RFT with periapical lesions. Dentists should consider these findings when caring for IBD patients by monitoring the evolution of periapical lesions of endodontically treated teeth.

Laparoscopic treatment in gastrointestinal bleeding due to Dieulafoy's lesion.

Dieulafoy's lesion is a rare cause of gastrointestinal bleeding. Produced by the erosion of aberrant vessels in the submucosa, usually at the gastric level. The jejunal location is unusual. Its diagnosis is complicated by the intermittent characteristic of bleeding, initially recommending the endoscopic approach. It is an unusual entity that must be taken into account in the differential diagnosis of gastrointestinal bleeding. Massive bleeding can occur, compromising the life of the patient. Initial endoscopic/radiological management is recommended, reserving the surgical approach for refractory bleeding for less invasive treatments.

La lesión de Dieulafoy es una causa infrecuente de hemorragia digestiva, producida por la erosión de vasos aberrantes en la submucosa, habitualmente gástrica. La localización yeyunal es inusual. Su diagnóstico es complicado por la característica intermitente del sangrado, recomendándose inicialmente el abordaje endoscópico. Se trata de una situación excepcional que debe tenerse en cuenta en el diagnóstico diferencial de la hemorragia digestiva. Puede producirse una hemorragia masiva que comprometa la vida del paciente. Es recomendable un manejo endoscópico/radiológico inicial; el abordaje quirúrgico se reserva para hemorragias refractarias a los tratamientos menos invasivos.

Influence of surgical site infection on oncological prognosis after curative resection for colorectal cancer: An observational single-institution study.

BACKGROUND: An exacerbated inflammatory response to post-operative infection could favor an environment in which residual viable tumor cells present in the surgical bed, bloodstream, or occult micrometastases can survive and progress to produce local or distant recurrence. In this regard, a surgical site infection (SSI) could be an important risk factor for disease progression. This study aimed to investigate the impact of SSI on long-term survival and recurrence of colorectal cancer. METHODS: Patients who underwent curative-intent resection for colorectal carcinoma between 2011 and 2013 were retrospectively analyzed. Overall and disease-free survival (DFS) and local recurrence rate for patients with and without SSI were analyzed. RESULTS: One hundred and thirty-eight patients were included in the study. Fifty-one (37%) patients showed SSI but revealed no differences in recurrence rate and overall survival compared with non-infected patients. However, the stratified analysis revealed that patients with an intra-abdominal abscess or an organ-space-infection showed a higher recurrence rate and a decreased 5-year overall and DFS. CONCLUSIONS: SSI may have an influence on the oncological prognosis and, therefore, could be considered a recurrence factor. Further multi-institutional studies are necessary to conclude a causal association.

ANTECEDENTES: Una respuesta inflamatoria exacerbada por una infección postoperatoria podría favorecer un entorno en el que células tumorales residuales viables presentes en el lecho quirúrgico, torrente sanguíneo o micrometástasis ocultas puedan sobrevivir y progresar para producir una recurrencia local o a distancia. En este sentido, una infección del sitio quirúrgico (ISQ) podría ser un factor de riesgo de progresión de la enfermedad. Este estudio tuvo como objetivo investigar el impacto de la ISQ en la supervivencia y recurrencia del cáncer colorrectal. MÉTODO: Todos los pacientes con carcinoma colorrectal sometidos a resección con intención curativa entre 2011 y 2013 fueron analizados retrospectivamente. Se analizó supervivencia global y libre de enfermedad y la tasa de recurrencia local en pacientes con cáncer colorrectal con y sin ISQ. RESULTADOS: Se incluyeron 138 pacientes. 51 (37%) sufrieron ISQ pero no mostraron diferencias en la tasa de recurrencia y supervivencia global respecto a los pacientes no infectados. Sin embargo, el análisis estratificado reveló que los pacientes con un absceso intraabdominal o una infección órgano-espacio mostraron una tasa de recurrencia más alta y una disminución en la supervivencia global y libre de enfermedad. CONCLUSIONES: La ISQ, en función de la gravedad y la respuesta inflamatoria que genera, puede influir en el pronóstico oncológico y, por lo tanto, podría considerarse un factor de recurrencia. Futuros estudios multicéntricos son necesarios para demostrar una posible asociación.

High Prevalence of Apical Periodontitis in Patients With Inflammatory Bowel Disease: An Age- and Gender- matched Case-control Study.

BACKGROUND: Deep carious lesions cause pulpitis, pulpal necrosis and, finally, apical periodontitis (AP). Root canal treatment (RCT) is the treatment of choice for AP, changing the tooth into a root-filled tooth (RFT). Several studies have linked AP and RFT to systemic diseases. Likewise, previous studies have also found an association among inflammatory bowel disease (IBD) and periodontal disease. This study aims to analyze the frequency of AP and RCT in IBD patients and healthy control subjects. METHODS: An age- and gender-matched case-control study design was used. The study group (SG) included 54 IBD patients (28 with Crohn´s disease, 26 with ulcerative colitis). Another 54 healthy subjects without IBD and age- and gender-matched were included in the control group (CG). The radiographic records were analyzed, and periapical radiolucencies were diagnosed as AP, using the periapical index (PAI). The statistical analysis was carried out using the Student t test, χ 2 test, and multivariate logistic regression. RESULTS: The presence of 1 or more teeth with radiolucent periapical lesions (RPLs) was found in 19 patients (35.2%) in the study group and in 9 subjects (16.7%) in the control group (P = 0.03). No differences were found among the 2 groups neither in the amount of teeth with AP nor in the number of RFTs (P > 0.05). However, multivariate logistic regression analysis adjusting for number of teeth and number of RFTs showed that patients with IBD have RPLs with higher likelihood than control patients (odds ratio, 5.7; confidence interval 95%, 1.7-19.1; P = 0.0048). CONCLUSIONS: Subjects with inflammatory bowel disease have higher prevalence of apical periodontitis. An oral health protocol should be established to address the higher prevalence of inflammatory oral processes.

Chimeric Anterolateral Thigh Flap for Total Thoracic Esophageal Reconstruction.

Gastric pull-up is generally the first choice for a total thoracic esophageal reconstruction. Malfunction of this gastric conduit is uncommon, but devastating when it occurs: it causes marked comorbidity to the patient, preventing oral intake and worsening quality of life. Secondary salvage thoracic esophageal reconstruction surgery is usually performed with free or pedicled jejunum flaps or colon interposition. We present a case of a total thoracic esophageal reconstruction with an externally monitored chimeric anterolateral thigh flap, extending from the cervical esophagus to the retrosternal gastroplasty remnant. Intestinal reconstructive techniques were not an available option for this patient.

Prevalence of apical periodontitis and frequency of root canal treatments in liver transplant candidates.

AIM: The purpose of this study was to investigate the prevalence of apical periodontitis (AP) and endodontic treatment in liver transplant candidates and control healthy subjects. MATERIAL AND METHODS: A descriptive cross-sectional study. Forty two liver transplant candidates (LTC) (study group) and 42 control subjects. Digital panoramic radiographs where used. Periapical status was scored according to the periapical index (PAI). Results were analysed statistically using the Chi-squared test and logistic regression. RESULTS: Radiographic signs of AP in one or more teeth was found in 79% of patients in the study group and in 50% of control subjects (p = 0.008; OR = 3.7; C. I. 95% = 1.4 - 9.5). One or more root-filled teeth (RFT) were found in 19% and 62% of study and control subjects, respectively (p = 0.0001; OR = 0.14; 95% C. I. = 0.05 - 0.38). Among LTC patients 14.7% of the teeth had AP, whereas in the control subjects 4.2% of teeth were affected (p= 0.0002). The percentage of RFT in the study and control groups was 1.5% and 6.8%, respectively (p = 0.0002). CONCLUSIONS: Liver transplant candidates have significantly higher prevalence of radiographic periapical lesions and lower frequency of RFT than controls healthy subjects.
