RESUMEN
BACKGROUND: Eagle jugular syndrome (EJS), recently identified as a cause of cerebrovascular disease (CVD) due to venous obstruction by an elongated styloid process (SP), is reported here alongside a case of concurrent de novo cerebral cavernous malformation (CCM). This study aims to explore the potential causal relationship between EJS and de novo CCM through a comprehensive literature review. METHOD: Systematic literature reviews, spanning from 1995 to 2023, focused on EJS cases with definitive signs and symptoms and de novo CCM cases with detailed clinical characteristics. Data on the pathophysiology and clinical manifestations of EJS, as well as potential risk factors preceding de novo CCM, were collected to assess the relationship between the two conditions. RESULT: Among 14 patients from 11 articles on EJS, the most common presentation was increased intracranial hypertension (IIH), observed in 10 patients (71.4%), followed by dural sinus thrombosis in four patients (28.6%). In contrast, 30 patients from 28 articles were identified with de novo CCM, involving 37 lesions. In these cases, 13 patients developed CCM subsequent to developmental venous anomalies (43%), seven following dural arteriovenous fistula (dAVF) (23%), and two after sinus thrombosis (6%). In a specific case of de novo brainstem CCM, the development of an enlarged condylar emissary vein, indicative of venous congestion due to IJV compression by the elongated SP, was noted before the emergence of CCM. CONCLUSION: This study underscores that venous congestion, a primary result of symptomatic EJS, might lead to the development of de novo CCM. Thus, EJS could potentially be an indicator of CCM development. Further epidemiological and pathophysiological investigations focusing on venous circulation are necessary to clarify the causal relationship between EJS and CCM.

BACKGROUND: There is individual variation in physiological ageing. Former very low birthweight (VLBW; birthweight < 1500 g) young adults may have less satisfactory measurements on some physiological parameters than term controls. We hypothesized that a summation score of physiological biomarkers that change with age would show VLBW adults to have a more advanced physiologic age than controls. METHODS: VLBW adults (229; 71% survivors of a national VLBW cohort) and term-born controls (100) were clinically assessed at 26-30 years. Ten measured physiological biomarkers were selected and measurements converted to z-scores using normative reference data. Between-group comparisons were tested for statistical significance for individual biomarker z-scores and a summation score. RESULTS: Nine of 10 biomarkers showed a mean z-score suggestive of older physiological age in the VLBW group versus controls. The observed mean difference in the summation score was highly significant (p < 0.001), representing a mean shift of 0.47 SD in the distribution of test scores for VLBW relative to controls. CONCLUSIONS: Utilizing a 10-biomarker score, VLBW young adults have a score indicative of poorer physiological functioning than term-born controls. Repeating these measures after an interval could provide insights into the comparative pace of ageing between VLBW and term-born adults. IMPACT: A summation score of 10 physiological biomarkers that are known to change with age shows that former very low birthweight adults have significantly poorer physiological functioning by the end of their third decade than term-born controls. This result adds to existing literature showing very preterm and very low birthweight young adults often have physiological and metabolic test results that are less satisfactory than those from term controls, despite mostly being in the normal range for age; for instance, higher systolic blood pressure. Although the pace of ageing in later years is yet to be established, the implications of this study are that preventative measures and lifestyle choices that impact on physiological ageing might have even greater importance for very preterm and very low birthweight graduates.

BACKGROUND: Increased intravascular volume has been associated with protection from acute kidney injury (AKI), but in patients with congestive heart failure, venous congestion is associated with increased AKI. We tested the hypothesis that intraoperative venous congestion is associated with AKI after cardiac surgery. METHODS: In patients enrolled in the Statin AKI Cardiac Surgery trial, venous congestion was quantified as the area under the curve (AUC) of central venous pressure (CVP) >12, 16, or 20 mm Hg during surgery (mm Hg min). AKI was defined using Kidney Disease Improving Global Outcomes (KDIGO) criteria and urine concentrations of tissue inhibitor of metalloproteinase-2 and insulin-like growth factor binding protein 7 ([TIMP-2]â [IGFBP7]), a marker of renal stress. We measured associations between venous congestion, AKI and [TIMP-2]â [IGFBP7], adjusted for potential confounders. Values are reported as median (25th-75th percentile). RESULTS: Based on KDIGO criteria, 104 of 425 (24.5%) patients developed AKI. The venous congestion AUCs were 273 mm Hg min (81-567) for CVP >12 mm Hg, 66 mm Hg min (12-221) for CVP >16 mm Hg, and 11 mm Hg min (1-54) for CVP >20 mm Hg. A 60 mm Hg min increase above the median venous congestion AUC above each threshold was independently associated with increased AKI (odds ratio=1.06; 95% confidence interval [CI], 1.02-1.10; P=0.008; odds ratio=1.12; 95% CI, 1.02-1.23; P=0.013; and odds ratio=1.30; 95% CI, 1.06-1.59; P=0.012 for CVP>12, >16, and >20 mm Hg, respectively). Venous congestion before cardiopulmonary bypass was also associated with increased [TIMP-2]â [IGFBP7] measured during cardiopulmonary bypass and after surgery, but neither venous congestion after cardiopulmonary bypass nor venous congestion throughout surgery was associated with postoperative [TIMP-2]â [IGFBP7]. CONCLUSION: Intraoperative venous congestion was independently associated with increased AKI after cardiac surgery.

OBJECTIVE: Ambient exposure to fine particles is associated with increased cardiovascular morbidity and mortality. Associations between occupational particulate matter (PM) exposure and cardiovascular disease have been studied less. The objective of this study was to examine associations between PM exposure and endothelial function among workers in Norwegian smelters. METHODS: We examined endothelial function with Endo-PAT equipment after a working day (WD) and on a day off (DO) in 59 furnace workers recruited from three metal smelters in Norway. The difference in baseline pulse amplitude (BPA) and reactive hyperemia index (RHI) between the 2 days was analysed in relation to individual exposure to PM < 250 nm (PM250) or the respirable aerosol fraction of particles, and adjusted for relevant covariates. RESULTS: The exposure to PM250 ranged from 0.004 to 5.7 mg/m3. The mean BPA was significantly higher on WD relative to DO (772 vs. 535, p = 0.001). This difference was associated with PM concentrations among participants ≥ 34 years, but not among the younger workers. Reactive hyperemia was significantly lower on workdays relative to days off (1.70 vs. 1.84, p = 0.05). This difference was observed only among participants above the age 34. No associations with PM exposure were observed. CONCLUSIONS: PM exposure was associated with higher BPA among participants older than 34 years. BPA reflects microvessel pulsatility. Our results may indicate an age-dependent cardiovascular susceptibility to PM exposure. Endothelial function measured by RHI was reduced on WD among participants 34 years and older, but we found no associations between PM exposure and RHI.

BACKGROUND: Cochlear implantation (CI) is an effective treatment option for patients with severe-to-profound hearing loss. When CI first started, it was recommended to wait until at least 4 weeks after the CI surgery for the initial activation because of possible complications. Advances in the surgical techniques and experiences in fitting have made initial activation possible within 24 h. OBJECTIVES: To compare the complaints and complications after early activation between behind-the-ear (BTE) and off-the-ear (OTE) sound processors and to show the impact of early activation on the electrode impedance values. METHOD: CI surgeries performed between March 2013 and July 2018 were retrospectively analyzed from the database. In total, 294 CI users were included in the present study. The impedance measurements were analyzed postoperatively at the initial activation prior to the stimulation, and 4 weeks after the initial activation in the first-month follow-up visit. A customized questionnaire was administered in the first-month follow-up fitting session to caregivers and/or patients who were using CI at least for 6 months. Medical records were also reviewed to identify any postoperative complications. RESULTS: In the early activation group, impedance values were significantly lower than in the control group (p < 0.05) at first fitting. At the first-month follow-up, no significant difference was found between the groups (p > 0.05). The most common side effects were reported to be edema (6.1%) and pain (5.7%) in the early activation group. In patients with OTE sound processors, the rate of side effects such as skin infection, wound swelling, skin hyperemia, and pain was higher than in patients with BTE sound processors; however, a statistical significance was only observed in wound swelling (p = 0.005). Selecting the appropriate magnet was defined as a problem for the OTE sound processors during the initial activation. CONCLUSION: This study revealed that early activation of CI was clinically safe and feasible in patients with BTE sound processors. When using OTE sound processors, the audiologists should be careful during the activation period and inform patients of possible side effects. The first fitting should be delayed for 4 weeks after CI for OTE sound processors. This current study is the first to report this finding with 5 years of experience in a large cohort.

PURPOSE: The purpose of our study was to evaluate effective ischemia and its associated complications using the limb occlusion pressure technique versus standard pneumatic ischemia technique. DESIGN: Single-centered randomized, controlled clinical trial. METHODS: One hundred sixty participants were randomized into two equal and parallel groups: (1) intervention group-LOP technique, and (2) control group-standard pneumatic ischemia technique. FINDINGS: Anesthetic incidences (need to administer analgesics for pain and/or hypnotics for anxiety) were similar in both groups. Statistically significant differences were observed for pain, hyperemia, and hospitalization, with higher values in the control group. Patients in the intervention group had, at 95% confidence, a 2.9 times greater chance of having optimal ischemia (assessed as 9 on the analog scale) than patients in the control group (odds ratio, 2.9; 95% confidence interval, 1.4 to 6.1). CONCLUSIONS: Intervention group patients had lower indexes of hyperemia, pain, and hospital stay.

BACKGROUND/INTRODUCTION: Diabetes and cardiovascular disease develop in concert with metabolic abnormalities mirroring and causing changes in the vasculature, particularly the microcirculation. The microcirculation can be affected in different parts of the body of which the skin is the most easily accessible tissue. PURPOSE: The association between diabetes and dermal microvascular dysfunction has been investigated in observational studies. However, the strength of the association is unknown. Therefore we conducted a systematic review with meta-analysis on the association between diabetes and dermal microvascular dysfunction as assessed by laser Doppler/laser speckle contrast imaging with local thermal hyperaemia as non-invasive indicator of microvascular functionality. METHODS: PubMed and Ovid were systematically searched for eligible studies through March 2015. During the first selection, studies were included if they were performed in humans and were related to diabetes or glucose metabolism disorders and to dermal microcirculation. During the second step we selected studies based on the measurement technique, measurement location (arm or leg) and the inclusion of a healthy control group. A random effects model was used with the standardised mean difference as outcome measure. Calculations and imputation of data were done according to the Cochrane Handbook. RESULTS: Of the 1445 studies found in the first search, thirteen cross-sectional studies were included in the meta-analysis, comprising a total of 857 subjects. Resting blood flow was similar between healthy control subjects and diabetes patients. In contrast, the microvascular response to local skin heating was reduced in diabetic patients compared to healthy control subjects [pooled effect of -0.78 standardised mean difference (95% CI -1.06, -0.51)]. This effect is considered large according to Cohen's effect size definition. The variability in effect size was high (heterogeneity 69%, p < 0.0001). However, subgroup analysis revealed no difference between the type and duration of diabetes and other health related factors, indicating that diabetes per se causes the microvascular dysfunction. CONCLUSION: Our meta-analysis shows that diabetes is associated with a large reduction of dermal microvascular function in diabetic patients. The local thermal hyperaemia methodology may become a valuable non-invasive tool for diagnosis and assessing progress of diabetes-related microvascular complications, but standardisation of the technique and quality of study conduct is urgently required.

INTRODUCTION: Impaired endothelial function, as assessed by brachial artery flow-mediated dilation (FMD), is an established risk factor for cardiovascular events. FMD is impaired in heart failure (HF) patients, but less is known about hyperemic brachial artery flow. We investigated the relationship between FMD and hyperemic flow with adverse clinical outcomes in HF patients. METHODS: Brachial artery FMD and hyperemic flow were assessed in 156 patients (70.5 % Male; 45.5% Caucasian; mean age (± SD) = 56.2 (±12.4) years) with HF and reduced left ventricular ejection fraction (LVEF). Cox proportional hazard models were used to assess the potential explanatory association of FMD and hyperemic flow with the composite outcome of death or cardiovascular hospitalization over a median 5-year follow-up period. RESULTS: Both FMD and hyperemic flow were negatively correlated with age, but unrelated to sex, race, body mass index, LVEF or N-terminal pro-B-Type natriuretic peptide (NT-ProBNP). Reduced hyperemic flow, but not FMD, was associated with an increased risk of death or cardiac hospitalization after controlling for traditional risk factors. CONCLUSION: The association of reduced hyperemic flow with increased risk of adverse clinical outcomes suggests that micro-vascular function may be an important prognostic marker in patients with HF.

BACKGROUND: Prior studies including the Framingham Heart Study have suggested associations between single components of air pollution and vascular function; however, underlying mixtures of air pollution may have distinct associations with vascular function. METHODS: We used a k-means approach to construct five distinct pollution mixtures from elemental analyses of particle filters, air pollution monitoring data, and meteorology. Exposure was modeled as an interaction between fine particle mass (PM2.5), and concurrent pollution cluster. Outcome variables were two measures of microvascular function in the fingertip in the Framingham Offspring and Third Generation cohorts from 2003 to 2008. RESULTS: In 1,720 participants, associations between PM2.5 and baseline pulse amplitude tonometry differed by air pollution cluster (interaction P value 0.009). Higher PM2.5 on days with low mass concentrations but high proportion of ultrafine particles from traffic was associated with 18% (95% confidence interval: 4.6%, 33%) higher baseline pulse amplitude per 5 µg/m and days with high contributions of oil and wood combustion with 16% (95% confidence interval: 0.2%, 34%) higher baseline pulse amplitude. We observed no variation in associations of PM2.5 with hyperemic response to ischemia observed across air pollution clusters. CONCLUSIONS: PM2.5 exposure from air pollution mixtures with large contributions of local ultrafine particles from traffic, heating oil, and wood combustion was associated with higher baseline pulse amplitude but not hyperemic response. Our findings suggest little association between acute exposure to air pollution clusters reflective of select sources and hyperemic response to ischemia, but possible associations with excessive small artery pulsatility with potentially deleterious microvascular consequences.

OBJECTIVES: Vascular involvement is a key feature of systemic sclerosis (SSc). Vascular changes are central to the pathogenesis of the disease and the assessment of vascular involvement has a prognostic value. This assessment therefore has a pivotal role in the management of SSc patients. The aim of our study was to evaluate post-occlusive reactive hyperaemia (PORH) in consecutive SSc patients and to test whether a PORH test might be a useful tool for the early diagnosis of SSc. METHOD: Between April 2011 and April 2015, 60 consecutive SSc patients (mean age 56 ± 15 years, females:males = 18:1) were enrolled in the study. The patients were divided into those with full-blown SSc (n = 50) and those with very early diagnosis of SSc (VEDOSS) (n = 10) according to the literature. Laser speckle contrast analysis (LASCA) was used to assess PORH. RESULTS: A statistically significant difference was detected in the post-ischaemic hyperaemic peak flow between VEDOSS and established SSc (424% vs. 137%, p = 0.0011). PORH peak flow decreased according to the capillaroscopic pattern (early = 419%, active = 163%, late = 145%, p = 0.0027). Moreover, a correlation between capillary density and peak flow was revealed (rho = 0.33, p < 0.01). CONCLUSIONS: These data show a different pattern of vascular involvement in VEDOSS compared to established disease that mirrors capillaroscopic changes. Functional features of very early and established disease seem to be the physiological counterpart of abnormalities detected by capillaroscopy. The POHR test might be a useful aid for further characterization of vascular involvement in SSc. In particular, blunted POHR might prove a tool to separate pre-clinical from full-blown SSc.

BACKGROUND: Short-term exposure to ambient air pollution has been associated with acute increases in cardiovascular hospitalization and mortality. However, causative chemical components and underlying pathophysiological mechanisms remain to be clarified. We hypothesized that endothelial dysfunction would be associated with mobile-source (traffic) air pollution and that pollutant components with higher oxidative potential to generate reactive oxygen species (ROS) would have stronger associations. METHODS: We carried out a cohort panel study in 93 elderly non-smoking adults living in the Los Angeles metropolitan area, during July 2012-February 2014. Microvascular function, represented by reactive hyperemia index (RHI), was measured weekly for up to 12 weeks (N = 845). Air pollutant data included daily data from regional air-monitoring stations, five-day average PM chemical components and oxidative potential in three PM size-fractions, and weekly personal nitrogen oxides (NOx). Linear mixed-effect models estimated adjusted changes in microvascular function with exposure. RESULTS: RHI was inversely associated with traffic-related pollutants such as ambient PM2.5 black carbon (BC), NOx, and carbon monoxide (CO). An interquartile range change increase (1.06 µg/m(3)) in 5-day average BC was associated with decreased RHI, -0.093 (95 % CI: -0.151, -0.035). RHI was inversely associated with other mobile-source components/tracers (polycyclic aromatic hydrocarbons, elemental carbon, and hopanes), and PM oxidative potential as quantified in two independent assays (dithiothreitol and in vitro macrophage ROS) in accumulation and ultrafine PM, and transition metals. CONCLUSIONS: Our findings suggest that short-term exposures to traffic-related air pollutants with high oxidative potential are major components contributing to microvascular dysfunction.

When food is heated to high temperatures, the characteristic "browning" generates advanced glycation end products (AGEs). AGEs are associated with an increased risk of cardiovascular disease, diabetes, and other adverse outcomes. Whether dietary AGEs are absorbed and are harmful to human health remains highly controversial. The objective of this study was to compare the effects of a diet high or low in AGEs on endothelial function, circulating AGEs, inflammatory mediators, and circulating receptors for AGEs in healthy adults. A randomized, parallel-arm, controlled dietary intervention was conducted for 6 wk with 24 healthy adults, aged 50-69 y, that compared isocaloric, food-equivalent diets that were prepared at either high or mild temperatures. Peripheral arterial tonometry, serum and urine carboxymethyl-lysine (CML), inflammatory mediators (interleukin-6, C-reactive protein, vascular adhesion molecule-1, and tumor necrosis factor-α receptors I and II), soluble receptor for AGEs, and endogenous secretory receptor for AGEs were measured at baseline and after 6 wk of dietary intervention. In the low-AGE diet group, the following changed from baseline to 6 wk (mean ± SE): serum CML from 763 ± 24 to 679 ± 29 ng/mL (P = 0.03) and urine CML from 1.37 ± 1.47 to 0.77 ± 2.01 µg/mL creatinine (P = 0.02). There were no significant changes in serum and urinary CML concentrations from baseline to follow-up in the high-AGE diet group. A high- or low-AGE diet had no significant impact on peripheral arterial tonometry or any inflammatory mediators after 6 wk of dietary intervention. In healthy middle-aged to older adults, consumption of a diet high or low in AGEs for 6 wk had no impact on endothelial function and inflammatory mediators, 2 precursors of cardiovascular disease.

BACKGROUND: The incremental value of CAC over traditional risk factors to predict coronary vasodilator dysfunction and inherent myocardial blood flow (MBF) impairment is only scarcely documented (MBF). The aim of this study was therefore to evaluate the relationship between CAC content, hyperemic MBF, and coronary flow reserve (CFR) in patients undergoing hybrid (15)O-water PET/CT imaging. METHODS: We evaluated 173 (mean age 56 ± 10, 78 men) patients with a low to intermediate likelihood for coronary artery disease (CAD), without a documented history of CAD, undergoing vasodilator stress (15)O-water PET/CT and CAC scoring. Obstructive coronary artery disease was excluded by means of invasive (n = 44) or CT-based coronary angiography (n = 129). RESULTS: 91 of 173 patients (52%) had a CAC score of zero. Of those with CAC, the CAC score was 0.1-99.9, 100-399.9, and ≥400 in 31%, 12%, and 5% of patients, respectively. Global CAC score showed significant inverse correlation with hyperemic MBF (r = -0.32, P < .001). With increasing CAC score, there was a decline in hyperemic MBF on a per-patient basis [3.70, 3.30, 2.68, and 2.53 mL · min(-1) · g(-1), with total CAC score of 0, 0.1-99.9, 100-399.9, and ≥400, respectively (P < .001)]. CFR showed a stepwise decline with increasing levels of CAC (3.70, 3.32, 2.94, and 2.93, P < .05). Multivariate analysis, including age, BMI, and CAD risk factors, revealed that only age, male gender, BMI, and hypercholesterolemia were associated with reduced stress perfusion. Furthermore, only diabetes and age were independently associated with CFR. CONCLUSION: In patients without significant obstructive CAD, a greater CAC burden is associated with a decreased hyperemic MBF and CFR. However, this association disappeared after adjustment for traditional CAD risk factors. These results suggest that CAC does not add incremental value regarding hyperemic MBF and CFR over established CAD risk factors in patients without obstructive CAD.

PURPOSE: To estimate the prevalence of self-reported "sensitive eyes" (SEs) in soft contact lens (CL) wearers, evaluate the clinical characteristics of patients with SEs, and examine the effect of refitting them with silicone hydrogel lenses. METHODS: After self-assessment, 2154 CL wearers were separated into SE and non-SE patients. Demographics, biometric data, wearing time, symptoms, and signs were compared between the two populations. Sixty-three SE patients were randomized into senofilcon A (senA) lenses and 65 into a non-senA arm (lotrafilcon B, omafilcon A, and balafilcon A lenses). The performance of senA lenses was compared against habitual and non-senA lenses 2 weeks later. RESULTS: A total of 12.2% of CL wearers reported SEs with their habitual CLs. No significant differences were noticed between SE and non-SE patients in sex, age, or refraction. The prevalence of dryness (43 vs 19%, p < 0.0001), irritation (25 vs 11%, p < 0.0001), redness (20 vs 6%, p < 0.0001), and stinging (6 vs 1%, p < 0.0001) was higher in SE patients. Average wearing time (13.0 vs 14.1 hours, p < 0.0001) was lower in this group. Limbal/bulbar hyperemia and corneal/conjunctival staining were not significantly different between the two populations. Senofilcon A increased the number of patients reporting no dryness (habitual vs senA, 20 vs 44%, p < 0.0003), irritation (22 vs 37%, p = 0.015), redness (52 vs 76%, p =0.009) and stinging (58 vs 77%, p = 0.012) but did not significantly affect clinical signs. Senofilcon A was significantly more efficient than non-senA lenses in improving dryness (scale of 0 to 3: senA vs non-senA, 0.64 vs 1.02, p = 0.0056), irritation (0.72 vs 1.16, p = 0.0015), and stinging (0.18 vs 0.53, p = 0.0049). CONCLUSIONS: A substantial proportion of CL wearers report SEs with their habitual lenses. These patients are characterized by a high prevalence of additional symptoms, which are not reflected in clinical signs. Senofilcon A, or lenses with similar properties, may help reduce these symptoms in SE patients.

The incidence of dry eye syndrome (DES) has increased due to wearing masks, utilizing digital devices, and working remotely during the pandemic. A survey was conducted during the COVID-19 pandemic to determine the prevalence of dry eye syndrome. A cross-sectional study investigated how prevalent DES is during COVID-19 in healthy patients aged 20-45 in the United States. An Ocular Surface Disease Index (OSDI) questionnaire was given to 40 individuals remotely from October 31, 2021, to December 1, 2021. The AOS and the OSDI survey were used to evaluate DES. The subjects were 29 years old on average (SD 14.14), with 23 males (57.5%) and 17 females (42.5%). According to the OSDI survey, low DES, moderate DES, and severe DES had prevalence rates of 15%, 77.5%, and 7.5%, respectively. White (W) people represent 50% of the population, while African Americans (AA) represent 35%, Asians represent 7.5%, and Hispanics represent 7.5%. Mild DES affected 77.5% of subjects, with 64.50% males and 35.50% females. According to the AOS objective grading system, mild (M) DES, moderate (MO) DES, and severe (S) DES had prevalence rates of 40%, 12.5%, and 15%, respectively. Linear regression was used to compare the two grading systems, and it demonstrated a strong relationship between the two grading systems.

BACKGROUND: Pathology related to complete denture-wearing will remain an important issue because of an increase in the ageing population. OBJECTIVE: To investigate the prevalence and the risk factors for denture-related stomatitis in the edentulous maxilla of older patients with a maxillary complete denture. MATERIAL AND METHODS: One hundred and six patients treated in the Department of Prosthodontics of the Athens Dental School were interviewed and clinically examined. The results were analysed using chi-square tests and multiple logistic regression. RESULTS: Denture stomatitis was recorded in 39.6% of the sample (pinpoint hyperaemia: 17%, diffuse erythema: 16%, papillary hyperplasia: 6.6%). Chi-square tests recorded significant associations between denture stomatitis and the continuous use of dentures (particularly the diffuse erythema type), the increased duration of denture experience and the poor retention of the maxillary denture. Other significant associations were recorded between the increased age of the current denture and pinpoint hyperaemia, and the reduced frequency of denture cleaning and papillary hyperplasia. Multiple logistic analysis revealed that the most important risk factor for denture stomatitis was the continuous use of the denture. CONCLUSION: The prevalence of denture stomatitis was high in denture users. Although many predisposing conditions were recorded, the most important risk factor was the continuous use of the denture. Therefore, appropriate advice on denture maintenance should be provided.

INTRODUCTION: Functional assessment of coronary stenoses is crucial for determining the correct therapeutic strategy. Age-related modifications in cardiovascular function could alter the functional significance of an intermediate coronary lesion. Therefore, the aim of the present study was to investigate the impact of age on fractional flow reserve (FFR) measurements in patients with intermediate coronary artery disease. METHODS: We included patients undergoing coronary angiography at our Division of Cardiology from June 2008 to February 2019 for elective indication or recent acute coronary syndrome and receiving FFR assessment for an intermediate coronary stenosis (angiographic 40-70% stenoses). FFR measurement was performed by pressure-recording guidewire (Prime Wire; Volcano Imaging System Philips Healthcare, San Diego, California, USA), after induction of hyperemia with intracoronary boluses of adenosine (from 60 to 720 µg, with dose doubling at each step). RESULTS: We included in our study 276 patients, undergoing FFR evaluation on 314 lesions, that were divided according to age (< or ≥70 years). Elderly patients displayed a higher cardiovascular risk profile and received more often specific therapy. We found significantly higher FFR values and lower Delta FFR and time to recovery in patients with age ≥70 years old even with high-dose adenosine. Elderly patients showed a trend in lower percentage of positive FFRs, especially with high-dose (P = 0.09). Overall, any FFR ≤ 0.80 was observed in 33.5% of younger patients and 21.1% of patients ≥70 years (P = 0.02). Results were confirmed after correction for baseline differences [adjusted odds ratio (95% confidence interval) = 0.60 (0.33-1.09), P = 0.08]. CONCLUSION: This is one of the first studies investigating the impact of age on the measurement of FFR with high-dose adenosine. Patients with age >70 years old with intermediate CAD are more likely to have higher FFR values and lower duration of hyperemia after adenosine boluses, as compared with younger patients.

Negative pressure wound therapy (NPWT) is usually applied in wound management and soft-tissue salvage after the development of complications. However, immediate postoperative application of NPWT over the flap coverage is seldom reported. We evaluate the effectiveness of immediate postoperative application of NPWT following fasciocutaneous or muscle flap coverage for lower leg reconstruction. A retrospective review of patients who underwent either fasciocutaneous or muscle flap coverage of lower leg soft-tissue defects applied with NPWT immediately after surgery was conducted in a level I trauma center. Sixteen patients, with an average age of 51.2 years, were included in the study. Nine patients had trauma-related soft-tissue loss, six had subsequent soft-tissue defects after debridement, and one had burn injury. Two patients had been treated with free anterolateral thigh flaps, 11 with pedicle flaps, and three with muscle flaps. All flaps survived except for those in two patients with venous congestion on postoperative day 1, which needed further debridement and skin grafting. Therefore, the use of immediate incisional NPWT is an alternative for wound care following flap coverage. The U-shaped design allows easy flap observation and temperature check. Furthermore, this method eliminates any concerns of vascular pedicle compression under negative pressure.

Purpose: In this study, we wanted to retrospectively evaluate the effect of the use of topical brimonidine on intraoperative bleeding and surgical hemostasis before strabismus surgery. Methods: Brimonidine tartrate 0.15% (Brimogut, Bilim Ilac, Turkey) eye drops were applied 6 and 3 min before surgery to 44 eyes of 22 patients in group 1 for vasoconstriction. Drops were not applied to 46 eyes of 23 patients in group 2. Preoperative and postoperative photographs and video images were taken. Black-and-white images were used to define the surface areas of the blood vessels. The surface area was calculated by counting the black pixels with ImageJ software. Results: In group 1, redness of eye was observed, on average, at preoperative 339.25 ± 11.52 pixels and intraoperative 247.93 ± 10.63 pixels (P < 0.001). But there was no change in group 2 (preoperative 338.87 ± 8.45 pixels to intraoperative 339.71 ± 9.52 pixels, P > 0.05). The incidence of intraoperative bleeding evaluated by the number of eyes on which cautery was used shows that it was significantly less in group 1 than in group 2 (P < 0.001). Conclusions: The use of topical brimonidine before strabismus surgery facilitates clear monitoring of anatomical structures during surgery by effectively controlling hemorrhage. In the postoperative period, it significantly reduces subconjunctival hemorrhage.

BACKGROUND AND PURPOSE: Transient global amnesia (TGA) is the inability to retain new information and to recall past events during a period of minutes or hours. Its etiology is unclear, and flow disturbances in the mesial temporal lobes secondary to venous congestion have been proposed as a potential cause. Ultrasonographic evaluation of the internal jugular vein (IJV) has demonstrated valvular insufficiency in TGA. The prevalence of valvular insufficiency in the IJV in patients with TGA was assessed. Subjects without TGA of similar sex, age, and vascular risk factor profiles served as controls. METHODS: A group of 142 patients with a clinical diagnosis of TGA within 7 days of the clinical event and 40 controls were prospectively evaluated. Venous Doppler examination of both IJVs was performed at baseline and after a manometer-controlled Valsalva maneuver. Valvular insufficiency was diagnosed when there was reflux for >0.8 seconds during the Valsalva maneuver. RESULTS: Valve insufficiency was found in at least one jugular vein in 113 of 142 patients with TGA (79.5%) and in 10 of 40 controls (25.0%), P<0.01. The right side was affected more often than the left side, P<0.01, and 26.8% of the patients had bilateral incompetence. CONCLUSIONS: Patients with TGA have a high prevalence of IJV valve insufficiency. This finding may have pathophysiologic implications. Doppler evaluation of the IJVs with dynamic maneuvers may help in the evaluation of this usually benign condition.
