Abstract
INTRODUCTION Anesthesia induction through volatile agents is a well-established technique in several fields but not in adult patients undergoing cardiac surgery. Successful inhalation induction requires a poorly soluble, reasonably potent and minimally irritant agent, and the benefits associated to this technique include reduced incidence of hypothermia and hypotension and lower costs when compared to some intravenous anesthetics agents. METHODS Fifty-six patients undergoing coronary artery bypass grafting were observed at the induction of general anesthesia with sevoflurane in oxygen by facial mask. All patients received 2% sevoflurane in 100% oxygen initially for 30 seconds. The inspired concentration of sevoflurane was increased to 7% until loss of consciousness and then reduced back to 2%. Next, intravenous 0.5 µg/kg sufentanil and 0.1 mg/kg pancuronium were administered. Volume-controlled ventilation was started before tracheal intubation. RESULTS All 56 patients tolerated the inhalational induction. No patient presented signs of airway irritation. Hypotension occurred in 30 patients and was managed with low dose phenylephrine. CONCLUSIONS This case series showed that inhalation induction is feasible and safe even in adult patients undergoing cardiac surgery.

Abstract
AIM The aim of our study was to evaluate, through prospective randomized study, the outcome and the immediate and late complications of the two types of surgery most widely used for degree III-IV haemorrhoids. METHODS A total of 122 patients with degree III and IV hemorrhoids were elected for surgical intervention and, randomly, underwent surgery for PPH or THD. We assessed the most common immediate postoperative complications. The patients have been followed for three months with a mean follow-up at 1 month and 3 months after surgery. Parameters taken into consideration were: bleeding, pain at rest and after evacuation, soiling, constipation and tenesmus. RESULTS Five patients in PPH group (7.9%) had a major postoperative bleeding, whereas no such episode occurred in THD group (P=ns). In percentage terms, VAS score was lower in THD group than in PPH group, although the difference was not statistically significant. Finally parameters values observed, during the follow-up, proved to be lower for THD group compared to PPH group. CONCLUSION PPH and THD are two surgical treatments for degree III and IV haemorrhoids with low perioperative complications and good results in the short term. However, our experience shows that better results in terms of pain and fewer postoperative complications are obtained after THD surgery, such surgery is less invasive and more adaptable to the needs of day surgery.

Abstract
BACKGROUND The unceasing and widespread increase of alcohol consumption represents an important problem for the European Union. For this reason, we wanted to investigate the patterns of alcohol consumption among high-school students of Rieti, a city in central Italy, and of surrounding rural areas. Furthermore, the study intends to investigate students' awareness on alcohol-related health risks and on the consequences of driving in a state of intoxication. METHODS In the investigation 7 schools including senior high schools and technical schools were involved, for a total of 669 students aged between 15 and 19 years. As part of a program of health education, a self-administered anonymous questionnaire was proposed to each student. A descriptive and multivariate analysis was carried out. RESULTS The prevalence of usual drinkers was equal to 12.7 per cent. The logistic regression analysis showed a statistically significant association between usual consumption of alcohol and the attendance of Technical Institutes (OR=3.43; 95% IC: 2.07 - 5.69), and the residence in rural areas (OR=2.19; 95% IC: 1.38 - 3.47). The area of residence in the multivariate analysis loses significance. Only 54.6 % of the students answered the questions regarding the state of driving under the effect of alcohol; of these, 11.0 % declared of having driven at least once under the effect of alcohol, whereas 18.0 % declared that they had been passengers of a driver who was drunk. The answer to the question whether the consumption of alcohol is harmful to health was "no" for 15.7 % of usual drinkers against 2.2 % of the non drinkers or occasional (episodic) drinkers. CONCLUSIONS Our study shows that the drinking habits of high school students of Rieti are worse for those attending technical schools. Usual drinkers show lower consciousness of alcohol-related harm. Our study may provide clues useful for the identification of the target population at high risk for alcohol abuse in order to create targeted prevention programs.

Abstract
We present here the case of a 66 year old man with a severe bilateral community acquired pneumonia secondary to dissemination after an intravesical instillation of bacilllus Calmette-Guerin (BCG). Diagnosis was based on positive polymerase chain reaction (PCR) for mycobacterium tuberculosis complex in bronchoalveolar lavage and on the finding on transbronchial biopsy of non necrotising granulomas histopathologically similar to the granulomas found in bladder biopsies. These findings were confirmed using a validated real time PCR assay demonstrating the presence of the BCG genome in transbronchial and bladder biopsies.

Abstract
PURPOSE Minced chondral fragments are becoming popular as a source of cells for cartilage repair, as a growing interest is developing towards one-stage procedures to treat cartilage lesions. The purpose of this study is to (A) compare cell outgrowth from cartilage fragments of adult and young donors using two different types of scaffolds and (B) evaluate the influence of transforming-growth-factor-β1 (TGF-β1) and granulocyte colony-stimulating factor (G-CSF) on chondrocyte behaviour. METHODS In part (A) cartilage fragments from adult and young donors were either loaded onto an HA-derivative injectable paste scaffold or onto an HA-derivative membrane scaffold. Construct sections were then examined for cell counting after 1, 2 and 3 months. In part (B) only membrane scaffolds were prepared using cartilage fragments from young donors. Constructs were cultured either in standard growth medium or in the presence of specific growth factors, such as TGF-β1 or G-CSF or TGF-β1 + G-CSF. After 1 month, construct sections were examined for cell counting. Expression of chondrocyte markers (SOX9, CD151, CD49c) and proliferative markers (β-catenin, PCNA) was assessed using immunofluorescence techniques, both in unstimulated construct sections and in cells from unstimulated and stimulated construct cultures. RESULTS Part (A): histological analysis showed age-dependent and time-dependent chondrocyte migration. A significant difference (p < 0.05) was observed between young and older donors at the same time point. No difference was detected between the two types of scaffolds within the same group at the same time point. Part (B): after 1 month, the number of migrating cells/area significantly increased due to exposure to TGF-β1 and/or G-CSF (p < 0.05). Immunofluorescence revealed that outgrowing cells from unstimulated scaffold sections were positive for SOX9, CD151, CD49c and G-CSF receptor. Immunofluorescence of cells from construct cultures showed an increase in β-catenin in all stimulated groups and an increased PCNA expression in G-CSF-exposed cultures (p < 0.05). CONCLUSION Outgrowing cells may represent a subset of chondrocytes undergoing a phenotypic shift towards a proliferative state. TGF-β1, and to a greater extent G-CSF, may accelerate this outgrowth. The clinical relevance of this study may involve a potential future clinical application of scaffolds preloaded with growth factors as an additional coating for chondral fragments. Indeed, a controlled delivery of G-CSF, widely employed in various clinical settings, might improve the repair process driven by minced human cartilage fragments during one-stage cartilage repair.

Abstract
The ocular tissues can be the site of a number of malignant tumors in adults. Approximately 5% to 10% of all skin tumors occur in the eyelid. Incidence studies indicate that basal cell carcinoma is the most frequent malignant eyelid tumor (90%) followed by squamous cell carcinoma (9%). A 55-year-old man presented a squamous cell carcinoma (SCC) of 8 mm diameter, localized in the middle third of the lower eyelid, 3 mm under the eyelid margin on the eyelids. The histopathologic examination of a biopsy specimen showed the typical features of squamous cell carcinoma. Photodynamic therapy (PDT) with topical 5-aminolevulic acid (ALA) after Frost suture was employed. Very good results were obtained with rapid healing, without invasiveness, and without anesthesia. There was no evidence of scar formation and no signs of recurrence at 6 months follow-up. Many therapeutic methods have been suggested for squamous cell carcinoma of the eyelid. We consider photodynamic treatment of eyelid skin malignancies to be of great interest and it may represent an interesting future perspective for their management especially when surgical intervention cannot be tolerated by the patient.

Abstract
PURPOSE Humeral resurfacing is a treatment option to conventional shoulder arthroplasty, conferring the advantages to preserve the bone stock and the normal joint geometry. Aim of the current study was to report clinical and radiographic mid-term outcomes in a population of 60 patients, aged 50 years or younger, who underwent shoulder resurfacing in osteoarthritis. METHODS The mean age was 48 ± 8.4, 36 were male and 24 female, dominant arm in 43 cases. Glenoid arthritis was treated in 36 cases (60 %) using a meniscus allograft in 22 cases, biologic patch in 4 cases and microfractures in 10 cases. Clinical and radiographic assessment was performed with Constant-Murley score and standard X-ray. RESULTS At an average follow-up of 44 months, the mean values of the constant score increased of 30 points (p < 0.05), the pain decreased of 4.56 points (p < 0.05) and the Simple Shoulder Test increased of 4.3 points (p < 0.05). We found lower scores (p > 0.05) in 9 patients (15 %) treated for glenoid arthritis using homologous meniscus (7 cases) and biologic patch (2 cases). A significant narrowing of joint space (5.92 mm postoperative versus 1.65 mm at 37 months) (p < 0.05) was found in the 22 cases treated with meniscus interposition. In 4 cases with type A2 preoperative glenoid morphology and in 9 cases type B1, we registered significantly lower scores compared with the overall study population (p < 0.01). Five unsatisfied patients (7 %), underwent to meniscus removal and glenoid reaming in 3 cases and conversion in total shoulder arthroplasty in 2 cases. CONCLUSIONS Resurfacing arthroplasty is an effective device in young patients with advanced glenohumeral arthropathy; however, the high rate of postoperative glenoid erosion and the failure of biologic allograft lead us to consider glenoid replacement as the best option to improve clinical outcomes.

Abstract
BACKGROUND Operative interventions of the urethra remain challenging procedures. The vascular onlay flap of the inner prepuce is a possible technique for short and long segment urethral defects. PATIENTS AND METHODS A total of 195 patients were surgically treated with a vascular prepuce flap between 1994 and 2010 at the Urology Department of Essen Medical University. Patient data were analyzed retrospectively and a questionnaire was sent to all patients. RESULTS Of the patients 115 answered the questionnaires and were included in the study. Of these 61 patients were treated in childhood due to hypospadias and 54 patients suffered from acquired urethral stricture. Major complications were postoperative fistulas in 8.2 % and 7.4 % and hematomas in 6.6 % and 11.1 % of cases, respectively. Operative revision had to be performed in 13.1 % and 14.8 % of cases and severe obstructive micturition problems (IPSS score ≥ 20) were observed in only 3.3 % and 11.1% of patients, respectively. Subjective overall satisfaction with the result of the operation was high (67.2 % and 88.9 %, respectively). CONCLUSION The vascular prepuce flap is a reliable method for correction of short and long segment urethral defects and is associated with high patient satisfaction.

Abstract
PURPOSE To evaluate granulocyte colony-stimulating factor (G-CSF) efficacy in accelerating bone regeneration following opening-wedge high tibial valgus osteotomy for genu varum. METHODS A phase II trial was conducted for evaluating the preoperative administration of G-CSF given at 10 μg/kg/day for 3 consecutive days with an additional half-dose 4 h before the opening-wedge high tibial valgus osteotomy. Overall, 12 patients (Group A) received G-CSF treatment, and the subsequent 12 patients (Group B) underwent surgery without G-CSF. The osteotomy gap was filled by a bone graft substitute. Bone marrow cell (BMC) mobilization was monitored by CD34+ve cell and clonogenic progenitor cell analysis. All patients underwent a clinical (Lysholm Knee Scale and SF-36) and radiographic evaluation preoperatively, as well as at given intervals postsurgery. RESULTS All patients completed the treatment program without major side effects; G-CSF was well tolerated. BMC mobilization occurred in all Group A patients, with median peak values of circulating CD34+ve cells of 110/μL (range 29-256). Circulating clonogenic progenitors paralleled CD34+ve cell levels. A significant improvement in Lysholm Knee Scale was recorded at follow-up in Group A compared to Group B. At the radiographic evaluation, there was a significant increase in osseointegration at the bone-graft junction in Group A at 1, 2, 3 and 6 months postsurgery compared to Group B. The computerized tomography scan of the grafted area at 2 months postsurgery showed no significant difference in the quality of the newly formed bone between the two Groups. CONCLUSIONS Although the limited number of patients does not allow firm conclusions, the study suggests that G-CSF can be safely administered preoperatively in subjects undergoing opening-wedge high tibial valgus osteotomy; in addition, the clinical, radiographic and CT monitoring indicate that G-CSF and/or mobilized BMCs may hasten bone graft substitute osseointegration.

Abstract
BACKGROUND Systemic sclerosis (SSc) is characterized by endothelial dysfunction and widespread microangiopathy. However, a macrovascular damage could be also associated. Aortic pulse wave velocity (aPWV) is known to be a reliable indicator of arterial stiffness and a useful prognostic predictor of cardiovascular events. Moreover, aPWV may be easily measured by non-invasive, user-friendly tool. Aim of our study was to evaluate aPWV alterations in a series of SSc patients. METHODS The aPWV was evaluated in 35 consecutive female SSc patients and 26 sex- and age-matched healthy controls. aPWV alterations were correlated with cardiopulmonary involvement. RESULTS A significant increase of aPWV was observed in SSc patients compared to controls (9.4 ± 3.2 m/s vs 7.3 ± 1 m/s; P = 0.002). In particular, 14/35 (40%) SSc patients and only 1/26 (4%) controls (P=0.0009) showed increased aPWV (>9 m/s cut-off value). Moreover, echocardiography evaluation showed an increased prevalence of right atrial and ventricular dilatation (atrial volume: 23.6 ± 6.2 mL vs 20.3 ± 4.3 mL, P=0.026; ventricular diameter 19.5 ± 4.9 mm vs 15.9 ± 1.6 mm; P=0.001) associated to higher values of pulmonary arterial systolic pressure (PAPs) in SSc patients (31.5 ± 10.4 mmHg vs 21.6 ± 2.9 mmHg; P<0.0001; 40% of SSc patients showed an abnormal PAPs). Clinically, SSc patients presented a reduction of six-minute walking test (413 ± 96 m vs 491 ± 49 m; P=0.001), not correlated with pulmonary function tests. Increased aPWV values were evidenced only in SSc patients >50 years old. Furthermore, altered aPWV was more frequently associated with limited cutaneous pattern, longer disease duration (≥ 5 years), and/or presence of anticentromere antibody (ACA). CONCLUSIONS A significantly higher prevalence of abnormally increased aPWV was evidenced in SSc patients compared to healthy controls. The possibility of more pronounced and diffuse vascular damage in a particular SSc subset (ACA-positive subjects with limited cutaneous scleroderma and longer disease duration) might be raised.

Abstract
PURPOSE This study proposes a single-step therapeutic approach for osteochondral defects using autologous cartilage fragments loaded onto a scaffold composed of a hyaluronic acid (HA) derivative, human fibrin glue (FG) and autologous platelet-rich-plasma (PRP), in a rabbit model. The aim is to demonstrate the in vitro outgrowth of chondrocytes from cartilage fragments and the in vivo formation of a functional repair tissue. METHODS In vitro: minced articular cartilage was loaded onto two different types of scaffold (paste or membrane) according to two different HA preparations (injectable HA-derivative or HA-derivative felt). In vivo: trochlear osteochondral defects were created in 50 adult rabbits, which were then assigned to 5 different treatment groups: cartilage fragments loaded onto membrane scaffolds with FG (Group 1) or without FG (Group 2); membrane scaffolds alone with FG (Group 3) or without FG (Group 4); empty defects (Group 5). Membrane scaffolds were used "in vivo" for simpler preparation and better adhesive properties. Repair processes were evaluated histologically and by immunohistochemistry at 1, 3, and 6 months. RESULTS An in vitro time-dependent cell outgrowth from cartilage fragments was observed with both types of scaffolds. At 6 months, in vivo, cartilage fragment-loaded scaffolds induced significantly better repair tissue than the scaffold alone using histological scoring. Repair in Group 2 was superior to that in any of the control groups (p < 0.05). CONCLUSION Autologous cartilage fragments loaded onto an HA felt/FG/PRP-scaffold provided an efficient cell source, and allowed for an improvement of the repair process of ostechondral defects in a rabbit model. Human FG, however, hampered the rabbit healing process. These results may have clinical relevance as they show the potential of a novel one-stage repair technique for osteochondral defects.

Abstract
Some bladder disorders, such as obstructive bladder and hyperactivity, may be caused partly by ischemia/reperfusion injury (I/R). The neuroprotective effects of estrogens were demonstrated in in vitro studies and a great interest in soy isoflavones (genistein and daidzein) as alternative to the synthetic estrogen receptor modulators for therapeutic use has been pointed out. The aim of this study was to investigate the effect of genistein and daidzein, on rat detrusor smooth muscle contractility and their possible neuroprotective role against I/R-like condition. Whole rat urinary bladders were subjected to in vitro anoxia-glucopenia (A-G) and reperfusion (R) in the absence or presence of drugs and response to electrical field stimulation (EFS) of intrinsic nerves evaluated. Furthermore rats were treated in vivo for 1 week with the phytoestrogens and the same in vitro protocol was applied to the ex vivo bladders. Antioxidant activity of genistein and daidzein on the A-G/R model was determined by measuring malonyldialdehyde (MDA). Moreover, hormones plasma levels were determined by radioimmunoassay. Genistein and daidzein administered either in vitro or in vivo showed significant neuroprotective effect and antioxidant activity. Testosterone and 17β-estradiol plasma levels were not modified by daidzein, while a significant decrease of testosterone in genistein treated rats was evident. Moreover both phytoestrogens significantly decreased detrusor contractions induced by EFS in a concentration-dependent manner. For being either neuroprotective and myorelaxant, genistein and daidzein could be considered a good lead for new therapeutic agents to protect the urinary bladder from hyperactivity and nerve damage.

Abstract
PURPOSE A well-structured system of appointments is mandatory in urological practices to provide a perfect work flow. A huge problem is appointments which are not cancelled by non-attending patients and remain free during consultation hours. METHODS An analysis of the electronic calendar of our group practice was performed from January 2010 to December 2010. RESULTS In 2010, 24,764 appointments in consultation hours were scheduled and of those 1,348 (5.4%) were not cancelled but not attended by the patients. Out of 1,760 X-ray investigations 59 (3.3%) patients did not show up and of 3,828 cystoscopy appointments, 109 (2.8%) patients did not cancel although they did not attend. A total of 440 outpatient appointments for surgery were scheduled and 8 (1.8%) patients did not attend but did not cancel surgery. Out of 176 (11.4%) scheduled spermiogram appointments, 20 patients did not bring a sample for analysis. CONCLUSIONS Due to the experiences of the authors, combined investigations, e.g. intravenous pyelogram (IVP) and cystoscopy on one day, should therefore be avoided in order to be able to cancel the second appointment when patients do not show up for the first appointment. In cases of surgical interventions, patients should be contacted by telephone 2-3 days prior to surgery for confirmation. Currently under German law there is no way to claim compensation for missed appointments from the patients. Thus, the only way to avoid large numbers of missed appointments is to keep those as low as possible, as soon as appointments are made and scheduled (e.g. no double appointments).
