Abstract
The study proposes a dynamic spatio-temporal profile of the distribution of tuberculosis incidence and air pollution in Romania, where this infectious disease induces more than 8,000 new cases annually. The descriptive analysis for the years 2012-2021 assumes an identification of the structuring patterns of mycobacterium tuberculosis risk in the Romanian population, according to gender and age, exploiting spatial modeling techniques of time series data. Through spatial autocorrelation, the degree of similarity between the analyzed territorial systems was highlighted and the relationships that are built between the analysis units in spatial proximity were investigated. By modeling the geographical distribution of tuberculosis, the spatial correlation with particulate matter (PM2.5) pollution was revealed. The identification of clusters of infected persons is an indispensable step in the construction of efficient tuberculosis management systems. The results highlight the link between the distribution of tuberculosis, air pollution and socio-economic development, which requires a detailed analysis of the epidemiological data obtained in the national tuberculosis surveillance and control program from the perspective of geographical distribution.

Abstract
OBJECTIVE To access the feasibility of palliative cystoprostatectomy/pelvic exenteration in patients with bladder/rectal invasion due to prostate cancer (PC). PATIENTS AND METHODS Twenty-five men with cT4 PC were retrospectively identified in the institutional databases of six tertiary referral centers in the last decade. Local invasion was documented by CT or MRI scans and was confirmed by urethrocystoscopy. Oncological therapies, local symptoms, previous local treatments, time from diagnosis to intervention and type of surgical procedure were recorded. Patients were divided into groups: ADT group (12 pts) and 13 pts without any history of previous local/systemic treatments for PCa (nonADT groups). Perioperative complications were classified using the Clavien-Dindo system. Overall survival (OS) was defined as the time from surgery to death from any cause. A Cox regression analysis, stratified for ISUP score and previous hormonal treatment (ADT) was also performed for survival analysis. RESULTS Ileal conduit was the main urinary diversion in both cohorts. For the entire cohort, complication rate was 44%. No significant differences regarding perioperative complications and complication severity between both subgroups were observed (p = 0.2). Median follow-up was 15 months (range 3-41) for the entire cohort with a median survival of 15 months (95% CI 10.1-19.9). In Cox regression analysis stratified for ISUP score, no statistically significant differences in OS in patients with and without previous ADT before cystectomy or exenteration were observed (HR 3.26, 95% CI 0.62-17.23, p = 0.164). CONCLUSION Palliative cystoprostatectomy and pelvic exenteration represent viable treatment options associated with acceptable morbidity and good short-term survival outcome.

Abstract
Abstract
Background
During the past decades, genetic research has reached new heights as next generation sequencing has rapidly taken over and genome-wide association studies (GWAS) have broug.
The purpose of the research is to determin high-risk variants (Single-Nucleotide-Variants,SNVs) associated with hypertension (HTA) in the Romanian population.
The current presentation asseses the final results of a 3 part study comprising the first and the largest GWAS on hypertension in Romanians.
Material
Methods The total cohort includes a number of 5690 individuals, of which 2190 with hypertension and 3500 heathy controls.
Genetic testing was performed at in Iceland.
A multiple GWAS assay has been performed for the identification of variants associated with hypertension, hypertension risk factors and hypertension comorbidities.
Results
Environmental (lifestyle) risk factors, such as smoking, alcohol consumption and coffee consumption, and also pathological risk factors, as are obesity and ageing, were analyzed in association with hypertension.
Tissue-specific protein expression, gene function and gene-gene interactions have been analyzed for assessing a possible biological explanation of the association between the identified related variants and HTA. Expression quantitative trait loci (eQTL) were assessed for variants in the reported locations for a better understanding of their involvement in HTA.
The results of the analysis revealed a number of over 5000 genetic variants statistically correlated with hypertension in the studied cohort, some well documented and in genes known to be involved in hypertension pathophysiology (clusters on chromosomes 1p36, 1q24, 3q24, 4p16, 5q12, 7q36, 12p12, 15q, 17q, 20q12, a.o. or CRNKL1, C19Orf12, CCDC51, C20Orf26, ZNF420, ZNF571, a.o. intragenic variants). Approx. 4100 SNVs were identified in correlation with diabetes mellitus and obesity.
Variants correlated with both hypertension and DM were identified (TBX20,ANK2, a.o. genes). Two other variant clusters (p=10–4–10–3) on chromosomes 19 (19q12) and 20 (20p11.21) revealed statistical correlations with both hypertension and obesity.
Conclusions
The present study found some important loci and clusters associated with HTA, which migh provide insights into the genetic architecture of this pathology.
The validity of these results for the Romanian population need to be confirmed by replication studies.
The current research is part of the EU ProMark, ROMCAN and AppGenEdu projects.

Abstract
PURPOSE Nephrolithiasis is a urological pathology that occurs at high rates and carries a great burden in terms of costs. The probability of recurrence is significant, necessitating improvements in prophylaxis and understanding of the disease mechanism. Despite the high heritability of this disease, only five genome-wide association studies (GWAS) of nephrolithiasis have been published. METHODS We selected 335 unrelated confirmed nephrolithiasis cases from two major sample collection projects (blood and buccal swabs) in Romania. DNA was extracted from whole blood and buccal swabs at deCODE Genetics (Reykjavik, Iceland) and genotyped. RESULTS Single-nucleotide polymorphisms identified from this GWAS implicated biological pathways and gene ontologies involving solute transport, renal physiology, and calcium homeostasis. Three loci especially emerged as candidates with a highly significant association with nephrolithiasis: RS10917682 in Regulator of G protein signaling 5, which has crucial roles in mRNA regulation and has been linked to renal cell carcinoma; RS1118528 in Solute carrier family 25 member 24, which encodes a mitochondrial ATP-Mg/phosphate carrier protein that likely influences a variety of important cellular pathways; and the TOX2-associated locus rs4437026, because TOX2 is upregulated in several tumor types and linked to tumor progression. CONCLUSION This study is the largest kidney stone-related GWAS reported in an Eastern European population and the first GWAS performed in a Romanian population to investigate the genetic risk factors for nephrolithiasis. We identified several loci that warrant further investigation for a better understanding of this highly heritable condition.

Abstract
Context Urolithiasis and obesity are now public health problems with an increased incidence worldwide. Management of urolithiasis in patients with morbid obesity is usually associated with higher morbidity and mortality compared to non-obese patients. ESWL is a nonsurgical procedure for the treatment of lithiasis. In obese patients the ESWL efficacy is influenced by the skin-to-stone distance or poorer detection of the calculus because of the fatty tissue. Objective To highlight the overweight or obese lithiasic patient profile that could be best treated by ESWL. Subjects and Methods We evaluated ESWL results in 1393 patients with kidney or ureteral stones between 5 and 20 mm. They were divided into 4 groups according to the BMI: Group A-overweight (BMI=25-30 kg/m2); Group B-grade I obesity (BMI=30-35 kg/m2); Group C-grade II obesity (BMI=35-40 kg/m2) and a control group of normal weight (BMI=18-25 kg/m2). Results Patients with a higher BMI required a greater number of ESWL sessions. A statistically significant greater number of patients with a waist circumference of >102 cm required more than 2 SWL sessions (p=0.007). Location of the stones in the pelvic ureter had the highest rate of success for obese patients (p=0.00001). The ESWL success rate in overweight and obese patients can be negatively influenced by BMI, abdominal circumference over 102 cm, and hardness of calculi reflected in the radiopacity on KUB. Conclusions In patients with grade II obesity, pyelocaliceal calculus and increased hardness, other urological alternatives to lithiasis should be considered from the beginning.

Abstract
Objective: To study the effects of intravitreal anti-Vascular Endothelial Growth Factor (VEGF) therapy with Avastin for wet Age-Related Macular Degeneration (AMD) on Benign Prostatic Hyperplasia (BPH)-related symptoms. Methods: An exploratory trial was conducted from August 1, 2013 to February 1, 2014, that included 14 male patients previously diagnosed with BPH, who were aged between 59 and 69 years. The trial was performed in Bucharest and involved two medical institutions: the Clinical Hospital of Eye Emergencies and the "Prof. Dr. Theodor Burghele" Hospital. This prospective study utilized both objective and subjective indicators to analyze the link between intravitreal anti-VEGF therapy for wet AMD and BPH. The evaluations consisted of uroflowmetry and International Prostate Symptom Score (I-PSS) assessments. Results: The maximum flow rate (Qmax) improved by an average of 5.05 ml/ sec in 9 patients, whereas the remaining 5 patients showed a slight decrease in Qmax (mean 1.6 ml/ sec). The I-PSS score improved, with an overall decrease of 1.18 points at follow-up compared to the initial score (mean initial score = 2.42; mean follow-up score = 1.24). Conclusion: The analysis revealed that anti-VEGF therapy for wet AMD had a significant positive effect on all BPH-related symptoms; patients reported improved urinary streams and decreased nocturia. Abbreviations: BPH = benign prostatic hyperplasia, AMD = age-related macular degeneration, VEGF = vascular endothelial growth factor, I-PSS = international prostate symptom score, Qmax = maximum flow rate, TSP-1 = thrombospondin-1, FGF-2 = fibroblast growth factor, mRNA = precursor messenger ribonucleic acid, PSA = prostate-specific antigen, DRE = digital rectal examination, AUR = acute urinary retention, COX2 = cyclooxygenase 2, QoL = quality of life.

Abstract
Vesicovaginals fistulas are the most common type of urogenital fistulas resulting after radical hysterectomy with or without radiotherapy. In most cases, surgery is necessary for healing. The present study was conducted over a period of 5 years. In all cases, the diagnosis was made on medical history, a complete clinical examination, intravenous pyelography and cystoscopy. Surgical closing technique of fistula tract could be applied in 28 cases (68.29%), out of which in 9 (22%) patients the exicision of the fistula tract and separate suture of the bladder and the vagina were performed while in 19 ( 46.3%) patients a flap was interposed too. All 25 patients who presented fistula after radical hysterectomy were feasible to surgical treatment of demolition of fistula and only 3 of 16 (18.75%) of the cases of hysterectomy and radiotherapy had indication for surgical closing technique of fistula tract. In 4 cases (9.7%) an external urinary diversion as the only therapeutic solution was performed. In 3 cases (7.3%) a percutaneous nephrostomy was inserted. Two patients (4.8%) presented vesicovaginal fistula and rectovaginal fistula as well. 24 (85.71%) of the 28 cases that have benefited from surgery remained continent, without loss of urine vaginally after the removal of urethro-bladder catheter. In 13 (31.7%) cases the success could not be obtained due to radiotherapy associated with hysterectomy. In the 25 cases where radiotherapy was not enforced, the success rate of surgery was 92%, while in patients who have benefited from radiotherapy too it goes down drastically (33%).The surgical closing technique of the vesicovaginal fistula has a very high success rate. The success of the operation can be obtained from the first surgery. The associated radiotherapy has a big influence in the approach of this pathology surgery.

Abstract
BACKGROUND AND AIM Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease worldwide, with a prevalence of 20%-40% in Western populations. The purpose of this article is to review data related to lifestyle changes in patients with NAFLD. METHOD We searched a public domain database (PubMed) with the following categories: disease (NAFLD, fatty liver, and non-alcoholic steatohepatitis [NASH]) and intervention (lifestyle intervention, diet, nutrition) with each possible combination through 25 September 2014, for relevant articles. Review of articles was restricted to those published in English. We selected the studies involving adult patients only. CONCLUSION There is no consensus as to what diet or lifestyle approach is the best for NAFLD patients. However, patients with NAFLD may benefit from a moderate- to low-carbohydrate (40%-45% of total calories) diet, coupled with increased dietary MUFA and n-3 PUFAs, reduced SFAs. More CRT are needed to clarify the specific effects of different diets and dietary components on the health of NAFLD patients. ABBREVIATIONS NAFL = Non-alcoholic fatty liver, NAFLD = non-alcoholic fatty liver disease, NASH = non-alcoholic steatohepatitis, HCC = hepatocarcinoma, BEE = basal energy expenditure, CRT = A small clinical randomized trial showed that short-term carbohydrate restriction is more efficacious in reducing intrahepatic triglyceride, IHT = intrahepatic triglyceride, VLCD = Very low calorie diets, AST = aspartate aminotransferases, SFAs = saturated fatty acids.

Abstract
INTRODUCTION Percutaneous nephrolithotomy (PCNL) represents a safe and efficient procedure in the surgical management of renal lithiasis. Nevertheless, surgeons have to face specific complications during and after the procedure, hemorrhage being one of the most common. In most cases the injuries are self-limited and do not need a surgical intervention. Renal arteriography with selective angiographic embolization is needed in patients with massive hemorrhage or continuous hematuria. Our objective was to evaluate the effectiveness of percutaneous transarterial embolization for the treatment of renal arterial post-PCNL bleeding. MATERIAL AND METHOD This retrospective study was performed between March 2007 and October 2012 and included 22 patients who had undergone renal embolization due to significant post-PCNL renal artery bleeding. The site, number, and type of bleeding lesions, and the result of the embolization procedure were recorded. We report on the incidence, treatment, radiological and clinical results of these serious vascular injuries at our institution. RESULTS Our study has included a large group of patients, the 95.45% angiographic success rate confirming that percutaneous transcatheter embolization is a valuable treatment for most renal vascular injuries. Renal angiography revealed pseudoaneurysm in 15 patients, arteriovenous fistula in 5 and arterial laceration in 2 patients. Significant risk factors on univariate analysis for severe hematuria requiring superselective angiography were multiple staghorn calculi, upper calix puncture and history of pyelonephritis. The severity of the hematuria after PCNL is influenced by many factors, including mean stone size and mean operative time and is correlated with duration of hospitalization and mean hemoglobin drop. CONCLUSIONS Percutaneous transarterial embolization of the injured vessel is an effective, minimally invasive and relatively easy procedure in experienced centers, with high rate of success and immediate benefits, thus saving the patient from the morbidity that results from severe renal bleeding.

Abstract
BACKGROUND In the case of buccal mucosa graft (BMG) urethroplasty for penile urethral strictures (PUS), it is supposed that the ventral onlay (VO) would not assure sufficient nutritional and mechanical support. Because VO requires only one ventral incision of the stenotic urethral segment and does not affect the urethral vasculature, we have design a prospective study related to this issue. METHODS We selected 27 consecutive patients with PUS, other than due to lichen sclerosus or to multiple hypospadias surgery. Surgical technique used: circular incision of the penile skin just below the glans, degloving without dartos, ventral median incision of the stenosed urethral segment, tailoring of the buccal mucosa graft over a 22 Ch catheter and fixation at the urethral mucosa edges, covering the graft with two lateral dartos flaps. RESULTS Follow-up consisted of clinical examination, uroflowmetry, and urethral ultrasonography. In one patient urethral fistula occurred and in two patients a fibrous diaphragm at the proximal end of the neourethra appeared. For the rest of the patients the neourethra lumen was stable, between 6 and 7mm at urethral ultrasonography control, the success rate being 88.89%. CONCLUSION The VO of BMG by the technique described, is a good solution for selected patients with PUS.

Abstract
The deep venous channels in the walls of the right atrium are not routinely described in medical treatises although their existence has been remarked from some time. Our study demonstrates that the right atrium is opened for some of the anterior veins of the heart through a venous channel located deep in the myocardium of the vestibule of the right atrium. We suggest that no Thebesian veins drain into this channel. We achieved anatomical dissection in 14 adult human cadaveric hearts, which had been fixed in formalin solution, and we found the channel in 75% of cases. These channels were measured, photographed and presented in detail. We highlighted the importance of the proximity with the tricuspid annulus in order to avoid incidents during tricuspid annuloplasty. The authors intend that through a qualitative study to draw attention to such a structure often ignored. This vascular structure and its role in cardiac physiology and pathology have not been investigated yet. Although not constant, specialists in cardiology and cardiac surgery should be informed about this basic detail on the endocardium morphology.

Abstract
There are still many things to be found out about interstitial cystitis/painful bladder syndrome (IC/PBS) because the pathological processes underlying the condition are not yet elucidated, biological markers of the condition are not yet available, and the type and severity of symptoms can vary, so, clearly defining the condition is not yet possible. For example, it is not clearly understood whether IC/PBS represents a systemic disease, if it is localized in the bladder, or if it was initially localized in the bladder and it later evolved into a systemic disease. This condition is best managed by using a multidisciplinary approach. Management requires a good integration and knowledge of all pelvic organ systems and other systems including musculoskeletal, neurologic, and psychiatric systems.

Abstract
During the last decades, erectile dysfunction was considered a direct consequence of aging and, although of a great concern for the affected patient, little was available to evaluate and treat this problem. If aging could not be invoked in all cases, than the psychogenic etiology was the only explanation. Over the coming years, a better understanding of the physiology involved in the penile process of tumescence and detumescence has allowed for better approach of each disease asociated with erectile dysfunction so that adequate treatment modalities can be applied to the pacient. As we all know, every pacient is a particular case. The development of modern PDE-5 inhibiters, along with other more or less invasive therapies, puts a new light on the medical approach of ED.

Abstract
Primary pure small cell carcinoma of the urinary bladder is an extremely rare and highly aggressive tumor with an average five-year survival rate of less than 10% as cited by multiple case reports. It accounts for about 0.5-1% of all bladder tumors. We present the case of a 44-years-old man, smoker (10 cigarettes/day) hospitalized in the Department of Urology, from the "Prof. dr. Th. Burghele" Hospital, Bucharest, for one month intermittent hematuria. Ultrasonography showed a sessile tumoral mass, sized 37/30mm. Transurethral resection of the tumor mass was performed and tissue fragments were sent to the pathologic lab to establish the histologic type, the degree of differentiation and invasion. Fragments of the tumor were fixed in 10% formaldehyde, paraffin embedded and processed as standard technique; the sections were stained with HE, VG and immunohistochemically with: CROMO, EMA, NSE, CD56, NK1, p53 and betaHCG. The microscopic examination reveled a tumor proliferation composed of two distinct components: extensive small cells areas and foci of typical low grade (G2) papillary urothelial carcinoma. The small cell are uniformly, round, with increased nucleo-cytoplasmic ratio, eosinophyl cytoplasm, hyperchromatic nuclei, finely granular chromatin and inconspicuous nucleoli. Immunohistochemical stains showed diffuse positive staining of the small cell component for CROMO, EMA, NSE, CD56, NK1 and urothelial carcinoma component stained focally for betaHCG. The rate of cell proliferation was increased (p53 - 80% positive reaction). Conclusions. A diagnosis of small cell carcinoma coexisting with low-grade urothelial carcinoma was established. Because of aggressive behavior and distinct treatment, the pathologist should watch out for the presence of small cell carcinoma component.

Abstract
Renal inflammatory pseudotumor is uncommon, benign tumor that has been classified into separate group but there is a risk that this lesion could be misdiagnosed. The aim of this work is to report a new case of 57-years-old man presented in our hospital with hematuria, minimal grade fever and right flank pain. Magnetic resonance imaging (MRI) and sonography revealed a tumor of the right mediorenal parenchyma, 2.5 cm in diameter. The patient underwent right nephroureterectomy under the diagnosis of renal cell carcinoma. Macroscopically examination carried out on the removed kidney showed a 2/2/1.5 cm yellowish, gelatinous, well circumscribed, mediorenal and pericaliceal mass. Fragments of the tumor were fixed in 10% formaldehyde, included in paraffin, and the sections were stained with HE, VG and immunohistochemically with vimentin (VIM), MNF116, SyN, smooth muscle actin (ACT), desmin, CD68, S100, HMB45, and CD117. The histological examination revealed a compact spindle cell proliferation, a hypocellular fibrous area in an edematous myxoid background infiltrated by small lymphocytes, histiocytes, some plasma cells and small bone area. The spindle cells were diffuse positive for VIM, ACT, CD68 and negative for desmin, MNF116, SyN, S100, HMB45, and CD117. The pathologic diagnosis was renal inflammatory pseudotumor, raising the problem of differential diagnosis, as the clinical and imagistic aspects are similar to those of a renal carcinoma and the problem in establishing a preoperative correct diagnosis.

Abstract
The aim of this study was to evaluate regulatory cell cycle factors in juxta-tumoral renal parenchyma in order to obtain information regarding early primary changes occurred in normal renal cells. Specimens of juxta-tumoral renal parenchyma were harvested from the tumoral kidney in 10 patients with no history of treatment before surgery. The expression of p53, Bcl-2, Rb and PCNA was studied by immunohistochemical methods in paraffin-embedded tissues. The apoptotic status was evaluated by flow-cytometry analysis following propidium iodide incorporation. The p53 protein expression was recognized in most of the cases (80%) with different intensities. High intensity apoptotic process detected in juxta-tumoral parenchyma seemed to be p53 dependent and well correlated with the low Bcl-2 expression. 70% of cases were Rb positive. In this type of tissue Rb has only an anti-proliferative and anti-tumoral role. PCNA was present in half of the cases being low expressed due to the tissue regenerating mechanism. Our data suggest that the high intensity of programmed cell death in this type of tissue is supported by the status of cell regulatory factors that control this process. Previous studies have demonstrated that healthy renal tissue has neither apoptosis nor mitotic activity. Juxta-tumoral renal tissue is also displaying normal morphology and DNA content (diploidy) but the microenvironmental status induced by the tumor presence prompts cells to choose death rather than malignant transformation. Further studies are necessary to emphasize if these results have a clinical relevance for the outcome of therapeutical approaches in renal carcinomas.

Abstract
The role of reactive oxygen species (ROS) in the pathogenesis of vascular diseases is well established, but few data exist on the mechanisms by which ROS induce endothelial cell (EC) death. We examined the conditions and the mechanisms by which oxidative stress induces EC death, using cultured confluent bovine aortic ECs exposed for 30 min to different concentrations of hydroxyl radicals (HO*) generated by hydrogen peroxide (H(2)O(2)) in the presence of 100 microM ferrous sulfate (FeSO(4)). Cell viability assays, Hoechst DNA staining, TUNEL (TDT-mediated dUTP-biotin nick end-labeling) analysis, agarose gel electrophoresis and annexin V assay were used to determine the effect of HO* on the viability of ECs, and to distinguish between apoptosis and necrosis. The results showed that at concentrations of up to 0.1 mM H(2)O(2)/FeSO(4), the large majority of cells are viable, except for approximately 12.5% death, which occurs by apoptosis. At a concentration of 0.2 mM H(2)O(2), the cell viability is reduced to 66%, while EC apoptosis remained at comparable values (14%). At high oxidative stress (0.5 mM H(2)O(2)), the cell viability was drastically reduced (approximately 39%), and the prevalent form of death was necrosis; apoptosis accounted for only approximately 17%. Together, these data indicate that: (1) HO* induce EC death either by apoptosis or necrosis and (2) the mechanisms of EC death differ as a function of the concentration of HO. Thus, the same insult can cause apoptosis and/or necrosis, as a function of the intensity rather than the nature of the insult.

Abstract
The microfluidity of cell membranes has been modified experimentally in endothelial cells and smooth muscle cells of bovine or monkey aorta cultured in vitro. Microfluidity was estimated by fluorescence depolarization measurements of diphenyl-hexatriene (DPH)-labelled cells. In both types of cells investigated, the arachidonic acid at concentration of 90 microM induced an increase in the microfluidity by 26-53% whereas the cholesterol at the same concentration produced a decrease in the microfluidity by 16-25%. The oleic acid in the range of 30 to 90 microM increased the monkey smooth muscle cell membranes microfluidity by 21-33% but did not change the microfluidity of endothelial and bovine aortic smooth muscle cells. The stearic acid did not influence the microfluidity of either type of cells under investigation. Cortisol at 90 microM changed the microfluidity of the bovine aortic endothelial cells plasmalemma depending on the incubation time. Possible factors of error in the physical measurements due to the extracellular localization of DPH have been identified.
