The aim of the present cross-sectional study was to estimate gingival recession (GR) prevalence and associated risk factors in young Greek adults. The study population consisted of 420 young adults (200 males and 220 females). All individuals were clinically examined and answered questions regarding their smoking status, educational level, and oral hygiene practices. In addition, the association between GR and the following aspects was assessed: sex, smoking status, educational level, plaque index, gingival index, calculus presence, and plaque control methods. Statistical analysis of data was accomplished using the multivariate linear regression analysis model. The average number of GR overall was 1.38 mm (standard deviation: 0.18 mm). Gingival index (P = 0.000) and smoking (P = 0.01) were the most important associated risk factors of GR, while sex, oral hygiene practices, presence of supragingival calculus, educational level, and plaque index were not significantly associated with it. Gingival inflammation, as determined by the gingival index, and smoking were the most important associated risk factors of GR. © 2013 Wiley Publishing Asia Pty Ltd. Source

Background: The authors evaluated the role of photodynamic cystoscopy in the detection of additional urothelial lesions, mainly carcinoma in situ, that would not be detected solely with white light cystoscopy, leading to disease understaging. Methods: From 2009 to 2011, 70 patients underwent white light cystoscopy, followed by photodynamic cystoscopy (blue light system, Karl Storz, Tuttlingen, Germany). Preoperatively they were instilled intravesically with 50. ml of Hexvix (Hexaminolevulinate hexylester). We recorded all lesions found with white light cystoscopy and the additional lesions revealed by blue light cystoscopy. Afterward all lesions were removed and sent for pathologic evaluation. Results: Seventeen patients (24.3%) had primary tumors while 53 patients (75.7%) had recurrent disease. In 53 out of 70 patients (75.7%) white light cystoscopy revealed urothelial lesions. In the rest 17 patients who had no findings with white light cystoscopy, blue light cystoscopy revealed 7 cases of Cis (41.2%) and 8 cases of dysplasia (47%). In the group of patients with visible lesions in white light cystoscopy photodynamic cystoscopy revealed additional carcinoma in situ in 22 patients. Altogether additional carcinoma in situ cases found with the aid of photodynamic cystoscopy were 29 out of 70 cases (41.4%). Conclusions: Photodynamic cystoscopy is the most efficient diagnostic procedure for flat urothelial lesions and especially for carcinoma in situ. It is significantly more sensitive than conventional white light cystoscopy in Cis diagnosis, thus reducing understaging of the disease and consequently improving recurrence and progression rates. © 2016 National Cancer Institute, Cairo University.

Background and objective: Parapneumonic effusions (PPE) that require drainage are referred to as complicated parapneumonic effusions (CPPE). Following resolution of these effusions, residual pleural thickening (RPT) may persist. We hypothesize that the concentrations of CRP in pleural fluid (CRP pf) and serum (CRP ser) can be used to identify CPPE and to predict RPT. Methods: All patients with non-purulent PPE, who were admitted to two tertiary hospitals during a 30-month period, were enrolled in the study. Baseline CRP pf and CRP ser levels were compared between patients with complicated or uncomplicated PPE, as well as between patients with or without RPT of >10 mm, 6 months after discharge from hospital. Cut-off values for identification of CPPE and prediction of RPT were determined by receiver operating characteristic curve analysis. Logistic regression analysis was performed to assess the association between CRP levels and RPT. Results: Fifty-four patients were included in the study. Patients with CPPE (n = 23) had significantly higher levels of both CRP pf and CRP ser than those with uncomplicated PPE. For identification of CPPE, a CRP pf level >78.5 mg/L and a CRP ser level >83 mg/L gave 84% and 47% sensitivity, with 65% and 87% specificity, respectively. Classical criteria (pleural fluid pH <7.20, LDH >1000 IU/L, glucose <600 mg/L) were superior for this purpose. A combination of classical biomarkers with CRP levels using an 'AND' or 'OR' rule improved the positive and negative predictive values, respectively. CRP ser was an independent predictor for development of RPT (adjusted OR 1.18). A CRP ser level >150 mg/L had 91% specificity and 61% sensitivity for prediction of RPT. Conclusions: This study demonstrated the value of CRP ser for prediction of RPT in patients with PPE. Moreover, when used in combination with classical biomarkers, CRP levels may be a useful adjunct for decision-making in relation to treatment of patients with non-purulent PPE. The accuracy of classical prognostic markers in patients with PPE is not ideal. When used in combination with classical biomarkers, CRP levels may be used to aid decision-making in the treatment of patients with non-purulent PPE, whereas serum CRP may be useful for predicting residual pleural thickening in these patients. © 2011 Asian Pacific Society of Respirology.

Therapeutic strategy for treating carotid artery near occlusion (CANO) has been controversial. The aim of this study was to review the literature concerning the invasive treatment of atherosclerotic CANO. A review was conducted of the English medical literature from 1980 to 2013 using Pub-Medand EMBASE database to find studies involving open or endovascular management of CANO. The search identified 20 reports describing invasive treatment of CANO encompassing 770 patients (77.7% men; mean age 66.3±5.2 years). A typical appearance of string sign was noted in nearly 60% of the patients. The vast majority (92.6%) were symptomatic. 479 (62.2%) patients underwent an open procedure, while 291 (38.8%) were treated endovascularly. The technical success rate for the endovascular procedures was 99%, while distal embolic protection devices were applied in most patients (66%). The 30 days procedural stroke rate was 2.1% and 2.4% for open and endovascular repair respectively. During a follow-up period spanning an average of approximately two years the ipsilateral cerebrovascular event rate was 5% and 1.2% for open and endovascular treatmentrespectively. Twenty five (5.2%) restenosis or occlusions were reported for the open procedures, while 13 (5.4%) were also documented for endovascular repair. The current literature concerning the invasive treatment of CANO is weak and cannot support any evidence based recommendation. The necessity to intervene as well as the best therapeutic strategy remains controversial. This review shows that the interventionon symptomatic CANO may consist a relatively safe and effective therapeutic strategy with low perioperative cerebrovascular morbidity for both treatment modalities, although durability and long-term outcomes should be further affirmed. The low incidence of this entity and the dearth of clear evidence support the need for a large multicenter registry to clarify the absolute indications for intervention and define the best therapeutic approach.

Background: Isolated acute abdominal aortic dissection (IAAAD) is considered an unusual clinical entity and is traditionally treated by open surgical repair. We report our single-center experience during the last 9 years, evaluating the outcomes after endovascular repair in this patient population. Methods: All patients with a diagnosis of IAAAD treated in our institute were included in this retrospective review. Between January 2004 and December 2012, 38 patients suffering from an acute aortic dissection were referred regionally for intervention to our department: 24 (63.2%) with a thoracic aortic dissection type B and 14 patients (36.8%, all male; median age, 65 years) with an IAAAD. Demographics, perioperative, procedure-specific, and follow-up data were prospectively aggregated in an electronic database. Results: Patients suffering from IAAAD presented with acute abdominal pain (n = 13) and acute lumbar pain (n = 1). Insufferable pain and enlargement of the aorta were the main indications for treatment. Mean (± standard deviation) maximal abdominal aortic diameter at presentation was 3.5 ± 0.94 cm (range, 2.6-5.1 cm). None of these patients had a concomitant thoracic aortic dissection. All patients were treated by endovascular means, with a primary technical success rate of 100%. Two patients (14%) died perioperatively from cardiac causes. Median hospital stay was 4.5 days (range, 3-16 days). During a mean follow-up period of 37.41 ± 23.56 months (range, 8-82 months; median, 32.5 months), two patients experienced primary treatment failure needing reintervention that led to a successful outcome. The cumulative free-from-reintervention rate was estimated 90.9% at 58 months (standard error, 8.7%). A full aortic remodeling without any events was noted in all other patients during the follow-up period. Conclusions: Based on our series, IAAAD may represent a not so rare clinical entity as generally thought, suggesting that it may be underdiagnosed. Endovascular treatment of IAAAD appears to be a feasible and efficient therapeutic approach and might be considered as the first-line treatment in all patients with suitable anatomy.
