Objectives: A retrospective study is made of the odontogenic infections treated in La Paz University Hospital (Madrid, Spain) during 2007 and 2008, with an epidemiological and microbiological analysis of a large group of patients. Study Design: A retrospective descriptive study was made, involving the consecutive inclusion of all patients with odontogenic infection requiring admission to our hospital in the period between January 2007 and December 2008. Results: A total of 151 patients were included, with a mean age of 40.3 years and a balanced gender distribution. The most frequently affected teeth were those located in the posterior mandibular segments, caries being the main underlying cause. Most isolates comprised mixed flora, particularly viridans streptococci, different species of Prevotella, Micromonas micros, and different species of Actinomyces. Susceptibility analysis of the microbial isolates showed a high percentage resistance to clindamycin (42.8% of all isolates), particularly among viridans streptococci. Conclusions: The use of antibiotics in head and neck infections requires updated protocols based not only on the existing scientific evidence but also on the epidemiological reality of each center. On the other hand, identification is required of the surgical factors determining infection and how they influence morbidity associated with this type of pathology.

Patients with type 2 MI and NIMI were older, with higher proportion of women and more comorbidities than patients with type 1 MI. Absolute mortality and the adjusted risk for all-cause mortality in both groups were significantly higher than that of patients with type 1 MI (39.7%, HR: 1.41 95% CI 1.02 to 1.94, p=0.038 and 40.0%, HR: 1.54 95% CI 1.16 to 2.04, p=0.002, respectively). Patients with type 2 MI and NIMI tended to present more readmissions due to heart failure (16.5%, HR: 1.55 95% CI 0.87 to 2.76, p=0.133 and 12.3%, HR: 1.15 95% CI 0.70 to 1.90, p=0.580) and less readmission rates due to acute coronary syndrome (ACS) than patients with type 1 MI (2.1%, HR: 0.11 95% CI 0.04 to 0.31, p<0.001 and 4.3%, HR: 0.22 95% CI 0.12 to 0.41, p<0.001), CONCLUSIONS: Patients diagnosed with type 2 MI and NIMI have higher rates of mortality and lower readmission rates for ACS compared with patients with type 1 MI.

BackgroundIncidental hepatocellular carcinoma (iHCC) is a histological finding after liver transplantation (LT) which relevance has been scarcely studied.Aimsto describe the histopathological features of iHCC and to determine its prognostic impact in terms of tumor recurrence and overall survival.MethodsObservational study including 451 consecutive adult LT patients (2000–2013). Patients aged<18, retransplanted or with early postoperative death were excluded. Median follow-up after LT was 58 months. Multiple Cox’s regression was used to assess the prognostic impact of iHCC on tumor recurrence and mortality while controlling for potential confounders.Results141 patients had known HCC before LT (31.3%). Among the remaining 310 patients, the prevalence of iHCC was 8.7% (n = 27). In the explanted liver, 36.2% of patients with known HCC and 25.9% of patients with iHCC trespassed Milan criteria (p = 0.30). Patients with known and iHCC had similar rates of multinodular disease (50.4% vs 55.6%; p = 0.62), macrovascular invasion (6.5% vs 3.7%; p = 0.58), microvascular invasion (12.9% vs 14.8%; p = 0.76) and moderate-poor tumor differentiation (53.9% vs 70.4%; p = 0.09). In the multivariate analysis, iHCC and known HCC had identical recurrence-free survival after controlling for histological features (RR = 1.06, 95%CI 0.36–3.14; p = 0.90). Cumulative 5-year overall survival rates were similar between patients with known and iHCC (65% vs 52.8% respectively; log rank p = 0.44), but significantly inferior as compared with patients without HCC (77.8%) (p = 0.002 and p = 0.007 respectively). Indeed, in the overall cohort, iHCC was an independent predictor of mortality (RR = 3.02; 95%CI 1.62–5.65; p = 0.001).ConclusionThe risk of tumor recurrence after LT is similar in patients with iHCC and known HCC. A close imaging surveillance is strongly recommended for patients awaiting LT in order to detect HCC prior to LT, thus allowing for an adequate selection of candidates, prioritization and indication of bridging therapies.
