HYPERVASCULAR LIVER LESIONS IN RADIOLOGICALLY NORMAL LIVER

ABSTRACT Background: The hypervascular liver lesions represent a diagnostic challenge. Aim: To identify risk factors for cancer in patients with non-hemangiomatous hypervascular hepatic lesions in radiologically normal liver. Method: This prospective study included patients with hypervascular liver lesions in radiologically normal liver. The diagnosis was made by biopsy or was presumed on the basis of radiologic stability in follow-up period of one year. Cirrhosis or patients with typical imaging characteristics of haemangioma were excluded. Results: Eighty-eight patients were included. The average age was 42.4. The lesions were unique and were between 2-5 cm in size in most cases. Liver biopsy was performed in approximately 1/3 of cases. The lesions were benign or most likely benign in 81.8%, while cancer was diagnosed in 12.5% of cases. Univariate analysis showed that age >45 years (p< 0.001), personal history of cancer (p=0.020), presence of >3 nodules (p=0.003) and elevated alkaline phosphatase (p=0.013) were significant risk factors for cancer. Conclusion: It is safe to observe hypervascular liver lesions in normal liver in patients up to 45 years, normal alanine aminotransaminase, up to three nodules and no personal history of cancer. Lesion biopsies are safe in patients with atypical lesions and define the treatment to be established for most of these patients.

Abstract Background Previous studies have shown the association between Campylobacter species infection and that environmental factors, poor oral hygiene in particular, are linked to an increased risk of esophageal cancer (EC). However, no study has reported on these factors in Thailand. Thus, this study’s objective was to evaluate the impact of the relationship between Campylobacter infection and environmental factors on EC incidence in the population of Thailand. Methods Data from a case–control study were collected from 105 newly diagnosed EC cases and 105 controls recruited from 2007 to 2017. Infection with Campylobacter spp. was detected in the formalin-fixed paraffin-embedded (FFPE) tissue of EC taken from gastroesophageal biopsy specimens obtained from the participants, and evaluated using TaqMan® real-time PCR. Multivariable logistic regression was performed to calculate the odds ratios (ORs) and perform data analysis. Results Smoking, alcohol use, a family history of cancer, history of gastroesophageal reflux disease, poor oral hygiene and Campylobacter spp. infection were shown to be significant risk factors for EC (p < 0.05). The combination of poor oral hygiene and infection with Campylobacter spp. constituted significant risk for EC (p < 0.001). In addition, the risk of EC in subjects co-infected with C. rectus and C. concisus that practiced poor oral hygiene was even higher and was significant (ORadj = 4.7; 95% CI 2.41–9.98; p = 0.003). Conclusions In Thailand, the major risk factors for EC are smoking status, alcohol drinking, family history of cancer, GERD, poor oral hygiene and Campylobacter spp. infection. This study found Campylobacter spp. prevalence to be associated with EC and appears to be enhanced by poor oral hygiene, suggesting that a combination of poor oral hygiene and Campylobacter species infection may together act as an important etiological risk factor for EC.

Abstract Objectives Oral and oropharyngeal squamous cell carcinoma (SCC) is the 10th most common cancer in the United States (8th in males, 13th in females), with an estimated 54,010 new cases expected in 2021, and is primarily associated with smoked tobacco, heavy alcohol consumption, areca nut use and persistent high-risk human papillomavirus (HPV). Family history of cancer (FHC) and family history of head and neck cancer (FHHNC) have been reported to play an important role in the development of OSCC. We aimed to investigate the role of FHC, FHHNC and personal history of cancer in first/second degree-relatives as co-risk factors for oral cancer. Methods This was a retrospective study of patients diagnosed with OSCC at the Division of Oral Medicine and Dentistry at Brigham and Women’s Hospital and at the Division of Head and Neck Oncology at Dana Farber Cancer Institute. Conditional logistic regressions were performed to examine whether OSCC was associated with FHC and FHHNC of FDRs and SDRs, personal history of cancer and secondary risk factors. Results Overall, we did not find an association between FHC, FHHNC and OSCC risk, whereas patients with a cancer history in one of their siblings were 1.6-times more likely to present with an OSCC. When secondary risk factors were considered, patients with a history of oral leukoplakia and dysplasia had a 16-times higher risk of having an OSCC. Conclusions Our study confirmed that a previous history of oral leukoplakia or dysplasia was an independent risk factor for OSCC. A positive family history of cancer in one or more siblings may be an additional risk factor for OSCC.

AbstractBackground:Additional high-quality evidence for predictors of peritonsillar abscess recurrence could lead to better-informed treatment decisions regarding tonsillectomy.Methods:In this study, 172 patients, who had been diagnosed and treated for peritonsillar abscess, were evaluated at follow up. A retrospective review of medical records and a telephone survey were performed. The clinical characteristics analysed included underlying disease, laboratory findings and computed tomography findings. Cox proportional hazard models were used to identify risk factors for peritonsillar abscess recurrence.Results:The recurrence rate of peritonsillar abscess was 13.9 per cent. Univariate analysis indicated that extraperitonsillar spread of the abscess (beyond the peritonsillar area) on computed tomography and a history of recurrent tonsillitis were associated with recurrence. Multivariate analysis also indicated that extraperitonsillar spread (p = 0.007; hazard ratio = 3.399) and recurrent tonsillitis history (p < 0.001; hazard ratio = 11.953) were significant risk factors for recurrence.Conclusion:Our results suggest that tonsillectomy may be indicated as a treatment for peritonsillar abscess in patients with a history of recurrent tonsillitis or extraperitonsillar spread on computed tomography.

Background.Methicillin-resistant Staphylococcus aureus (MRSA) is a major pathogen in hospital-acquired infections. MRSA-colonized inpatients who may benefit from undergoing decolonization have not been identified.Objective.To identify risk factors for MRSA infection among patients who are colonized with MRSA at hospital admission.Design.A case-control study.Setting.A 146-bed Veterans Affairs hospital.Participants.Case patients were those patients admitted from January 2003 to August 2011 who were found to be colonized with MRSA on admission and then developed MRSA infection. Control subjects were those patients admitted during the same period who were found to be colonized with MRSA on admission but who did not develop MRSA infection.Methods.A retrospective review.Results.A total of 75 case patients and 150 control subjects were identified. A stay in the intensive care unit (ICU) was the significant risk factor in univariate analysis (P<.001). Prior history of MRSA (P = .03), transfer from a nursing home (P = .002), experiencing respiratory failure (P<.001), and receipt of transfusion (P = .001) remained significant variables in multivariate analysis. Prior history of MRSA colonization or infection (P = .02), difficulty swallowing (P = .04), presence of an open wound (P = .002), and placement of a central line (P = .02) were identified as risk factors for developing MRSA infection for patients in the ICU. Duration of hospitalization, readmission rate, and mortality rate were significantly higher in case patients than in control subjects (P< .001, .001, and <.001, respectively).Conclusions.MRSA-colonized patients admitted to the ICU or admitted from nursing homes have a high risk of developing MRSA infection. These patients may benefit from undergoing decolonization.

Background and objectives: To investigate the risk factors for emphysematous cystitis (EC) compared to those of acute cystitis (AC) to increase clinicians awareness of the possibility for the aggravation of patient status. Materials and methods: We retrospectively reviewed a total of 54 patients who were hospitalized with a diagnosis of EC by abdominal computed tomography (CT) scan from 2006 to 2020. The control group included 92 patients who were hospitalized for the treatment of AC in the same period. We sought to identify the clinical features and predisposing diseases, such as age, sex, diabetes mellitus (DM), hypertension (HTN), cerebrovascular accident (CVA), chronic kidney disease (CKD), neurogenic bladder (NB), history of urinary tract infection (UTI), and emphysematous pyelonephritis (EPN), that were associated with the development of EC. Results: The median (interquartile range (IQR)) age of the patients with EC was older than that of the patients with AC (78.5 (15.3) years (range: 52–100) vs. 70.0 (26.5) years (range: 28–97 years)). Sepsis and mortality occurred only in the EC group (48.1% and 11.1%, respectively). The univariate analysis of predisposing factors revealed that age, DM, HTN, CVA, CKD, and NB were significantly associated with EC. In the multivariate analysis, DM (OR, 6.251; 95% CI, 2.254–17.250; p < 0.001), CKD (OR, 18.439; 95% CI, 3.421–99.404; p = 0.001), NB (OR, 7.374; 95% CI, 1.993–27.285; p = 0.003) were associated with EC. Conclusions: The results of this study revealed that DM, CKD, and NB were significant risk factors for EC. The tendency toward sepsis and high mortality underscore the need for careful observation while treating patients with EC with the risk noted above.

Abstract BACKGROUND Meningiomas are the most common primary central nervous system tumors. Risk factors for meningiomas including obesity, height, history of allergy/atopy or autoimmune diseases, have been previously assessed with conflicting results. We reviewed a large cohort of Israeli adolescents in order to assess potential risk factors for the development of meningiomas. METHODS This study analyzed a cohort of 2,035,915 Jewish men and women who underwent obligatory physical examination when aged 16 to 19 years, from 1967 to 2011. Meningioma incidence was identified by linkage to the national cancer registry. Cox proportional hazard models were used to estimate the hazard ratios for meningioma according to sex, body mass index (BMI), height, history of allergic and autoimmune disease. RESULTS Linkage of the adolescent military database with the Israeli cancer registry identified 480 cases (152 males and 328 females) of meningioma during a follow up of 40,304,078-person years. The median age at diagnosis of meningioma was 42.1 ± 9.4 (range 17.4–62.6). On univariate analysis, only female gender (p< 0.01) and height (p< 0.01) were associated with risk for meningioma in the total study population. When stratified by gender, height remained a significant risk factor only in men. Spline analysis in the men group showed the minimum risk at a height of 1.62 meters and a statistically significant increase in the risk for meningioma at heights taller than 1.85 meters. BMI, past medical history including asthma, diabetes, and atopic and autoimmune diseases, were not associated with meningioma risk. CONCLUSION in this large population study, we found that sex and taller height in adolescent males was associated with an increased risk of adult meningioma.

Transmetatarsal Amputation

Category: Midfoot/Forefoot; Diabetes; Other Introduction/Purpose: Non-traumatic lower extremity amputations (LEA), especially those performed in dysvascular and diabetic patients, are known to have poor long-term prognosis. Perioperative mortality has been reported at between 4 and 10%, and the 1 and 5 year mortality rates range between 22-33% and 39-69%, respectively. While poor outcomes in these patients have been described, there is no consensus as to the predictors of mortality. The purpose of the study is to determine the percentage of patients who had a complication following transmetatarsal amputation (TMA) and identify associated risk factors for complications and mortality. Methods: We queried our institution’s administrative database to identify 247 TMA procedures performed in 229 patients between January, 2002 and December, 2016. Electronic health records were reviewed to document complications defined as reoperation, amputation and mortality. Mortality was also verified using the National Death Index. Additionally, we recorded risk factors including diabetes, A1c level, end stage renal disease (ESRD), cardiovascular disease (CVD), peripheral vascular disease (PVD), history of revascularization, contralateral amputation, and neuropathy. The majority of the study patients were males (157, 69%) and the average age was 57 years (range 24-91). The median BMI was 28 (range 16-58) and 29% of the study patients were obese with a BMI ≥ 30. Fishers Exact tests were used to compare categorical variables. Kruskal-Wallis and Independent T-tests were used to compare numeric data. All data were analyzed using SAS/STAT software version 9.4 (Carey, NC) and a 0.05 level of significance was defined apriori. Results: The conversion rate to below (BKA) or above knee amputation (AKA) was 26% (64 of 247). Males (p=.0274), diabetics (p=.0139), patients in ESRD (p=.019), and patients with a history of CVD (p=.0247) or perioperative revascularization (p=.022) were more likely to undergo further amputation following an index TMA. BMI was significantly higher in patients requiring BKA/AKA (p=.0305). There were no significant differences in age (p=.2723) or A1c levels (p=.4219). The overall mortality rate was 35% (84 of 229). Diabetes (p=.0272), ESRD (p=.0031), history of CVD (p<.0001) or PVD (p=.0179) were all significantly associated with mortality. Patients who died were significantly older (p=.0006) and had significantly higher A1c levels (p=.0373). BMI was not significantly associated with mortality. Twenty-two patients who had 23 further amputations subsequently died. Conclusion: In our series of patients undergoing TMA, 26% underwent further amputation and 35% of patients died. Conversion rate to BKA or AKA occurred at a high rate regardless of preoperative revascularization or the use of tendo-achilles or gastrocnemius lengthening procedures. Male sex, diabetes, ESRD, history of CVD or revascularization are significant risk factors for further amputation. ESRD, diabetes, history of CVD or PVD, older age and higher A1c levels are significant risk factors for mortality. These data provide useful insight into risk factors to be emphasized when counseling patients and their families to establish realistic postoperative expectations.

Background and Objectives: Retinopathy of prematurity (ROP) is the leading cause of blindness in preterm infants. We studied the relationship between different perinatal characteristics, i.e., sex; gestational age (GA); birth weight (BW); C-reactive protein (CRP) and lactate dehydrogenase (LDH) concentrations; ventilation, continuous positive airway pressure (CPAP), and surfactant administration; and the incidence of Stage 1–3 ROP. Materials and Methods: This study included 247 preterm infants with gestational age (GA) < 32 weeks that were successfully screened for ROP. Univariate and multivariate binary analyses were performed to find the most significant risk factors for ROP (Stage 1–3), while multivariate multinomial analysis was used to find the most significant risk factors for specific ROP stages, i.e., Stage 1, 2, and 3. Results: The incidence of ROP (Stage 1–3) was 66.40% (164 infants), while that of Stage 1, 2, and 3 ROP was 15.38% (38 infants), 27.53% (68 infants), and 23.48% (58 infants), respectively. Following univariate analysis, multiple perinatal characteristics, i.e., GA; BW; and ventilation, CPAP, and surfactant administration, were found to be statistically significant risk factors for ROP (p < 0.001). However, in a multivariate model using the same characteristics, only BW and ventilation were significant ROP predictors (p < 0.001 and p < 0.05, respectively). Multivariate multinomial analysis revealed that BW was only significantly correlated with Stage 2 and 3 ROP (p < 0.05 and p < 0.001, respectively), while ventilation was only significantly correlated with Stage 2 ROP (p < 0.05). Conclusions: The results indicate that GA; BW; and the use of ventilation, CPAP, and surfactant were all significant risk factors for ROP (Stage 1–3), but only BW and ventilation were significantly correlated with ROP and specific stages of the disease, namely Stage 2 and 3 ROP and Stage 2 ROP, respectively, in multivariate models.

AbstractBACKGROUNDIncreases in circulating LDL cholesterol (LDL-C) and high-sensitivity C-reactive protein (hsCRP) concentrations are significant risk factors for cardiovascular disease (CVD). We assessed direct LDL-C and hsCRP concentrations compared to standard risk factors in the Framingham Offspring Study.METHODSWe used stored frozen plasma samples (−80 °C) obtained after an overnight fast from 3147 male and female participants (mean age, 58 years) free of CVD at cycle 6 of the Framingham Offspring Study. Overall, 677 participants (21.5%) had a CVD end point over a median of 16.0 years of follow-up. Total cholesterol (TC), triglyceride (TG), HDL cholesterol (HDL-C), direct LDL-C (Denka Seiken and Kyowa Medex methods), and hsCRP (Dade Behring method) concentrations were measured by automated analysis. LDL-C was also calculated by both the Friedewald and Martin methods.RESULTSConsidering all CVD outcomes on univariate analysis, significant factors included standard risk factors (age, hypertension, HDL-C, hypertension treatment, sex, diabetes, smoking, and TC concentration) and nonstandard risk factors (non-HDL-C, direct LDL-C and calculated LDL-C, TG, and hsCRP concentrations). On multivariate analysis, only the Denka Seiken direct LDL-C and the Dade Behring hsCRP were still significant on Cox regression analysis and improved the net risk reclassification index, but with modest effects. Discordance analysis confirmed the benefit of the Denka Seiken direct LDL-C method for prospective hard CVD endpoints (new-onset myocardial infarction, stroke, and/or CVD death).CONCLUSIONSOur data indicate that the Denka Seiken direct LDL-C and Dade Behring hsCRP measurements add significant, but modest, information about CVD risk, compared to standard risk factors and/or calculated LDL-C.
