Abstract
The cardinal diagnostic signs of neurofibromatosis type 1 (NF1) are Lisch nodules of the iris and optic pathway gliomas. Retinal mi-crovascular alterations have been described but with uncertain signi-ficance. Choroidal nodules, detectable with near-infrared reflectance (NIR) imaging, are present in most cases and have been proposed as a new diagnostic criterion. Recently, a study reported the presence of unusual dilated choroidal vessels, visible through NIR examination. We report a case of a 65-year-old patient with NF1. Best-corrected visual acuity was 20/20 with a refractive error of +2.75 diopters in both eyes. Anterior segment examination revealed Lisch nodules in both eyes. At NIR imaging the patient presented typical choroidal alterations in both eyes. No retinal vessel anomalies were detected. The patient presented enlarged choroidal vessels in the left eye, first detected by NIR and then analyzed through enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT). These vessels extended from the choroidal-scleral junction to the outer border of the retinal pigment epithelium/Bruch's layer. The choriocapillaris layer was absent above the dilated vessels. The presence of enlarged choroidal vessels may be considered as a novel distinctive ophthalmologic aspect of NF1, but further studies are necessary.

Abstract
Purpose To evaluate the diagnostic ability of pachymetric indexes obtained with Spectral Domain Optical Coherence Tomography (SD-OCT) for early detection of keratoconus (Kc). Methods 64 patients with Kc in at least one eye (95 eyes, 46 men and 18 women, average age 27.84 ±13.50), 59 healthy control subjects (100 eyes, 28 men and 31 women, average age 27.15 ±16.14). All patients underwent detailed clinical examination, topography and anterior segment OCT. 37 subjects (37 eyes, 27 men and 10 women, average age 24.23 ± 14.24) having one eye with manifest Kc and the fellow eye without clinical signs of Kc were identified. We studied two groups of pachymetric indexes: C1-C2, M1-M2, pCLMI, Pmin-P2 (Group 1 indexes) and PPD, PSD, PSSD and PASD (Group 2 indexes). A ROC (Receiver Operating Characteristic) curve was developed to compare the diagnostic accuracy, relative sensitivity and specificity for each index. Results In manifest keratoconus, C1-C2, M1-M2, and pCLMI are significantly higher compared to the control group (P<0.0001); for suspect keratoconus, all Group 1 indexes are significantly higher compared to healthy subjects (P<0.0001) excluding M1-M2 obtained using a constant area circle (P = 0.02). Furthermore, for manifest and suspect keratoconus, PPD, PSD, PSSD and PASD are significantly higher compared to the control group (P <0.0001). Conclusion The studied pachymetric indexes in patients with Kc have high diagnostic accuracy and are statistically significant when compared with healthy subjects (p<0.0001) and can provide a useful tool for keratoconus screening.

Abstract
This article describes the improvement of organ donation and transplantation in Italy during 1995–1999. In 1999, the mean number of donors per million population reached 13.7 in Italy. In addition, an analysis regarding major characteristics of donors and recipients is presented, focusing particularly on donor characteristics that have changed in the past 5 years. Despite the encouraging results, further efforts are required to reach the European mean, which still remains higher than the Italian national mean. In particular, an increase of organ donation and procurement in regions with a poor activity in this field is crucial. A 1999 law on donation and transplantation should help in solving problems that continue to affect part of the nation, especially preparing the healthcare staff dedicated to organ retrieval to promote organ procurement.

Abstract
OBJECTIVE Intracameral mydriatics using epinephrine associated with lidocaine have been reported as efficacious in reducing intraoperative floppy iris syndrome (IFIS) complications during cataract surgery. The aim of this study was to verify the efficacy of intracameral epinephrine without intracameral lidocaine as prophylaxis against IFIS in patients on tamsulosin. MATERIALS AND METHODS This was a retrospective study on the results of cataract surgery in 18 patients on therapy with tamsulosin. Patients had undergone routine phacoemulsification in one eye. Successively, they underwent phacoemulsifcation in the fellow eye using non preserved intracameral epinephrine 1:4000 diluted with BSS. Intraoperative complications during cataract surgery had been documented and IFIS was graded based on iris billowing, miosis or iris prolapse. Follow-up was 3 months. RESULTS Thirty-six eyes of 18 patients were included in the evaluation. The incidence of IFIS was significantly higher in the eyes where routine phacoemulsificaton had been performed (100%) with respect to eyes where phacoemulsification was carried out using intracameral epinephrine (33%) (Chi Square test =15.12, p<0.001). In routine phacoemulsification 16 eyes showed iris billowing, 14 eyes had some extent of miosis and 14 eyes had tendency to iris prolapse. In phacoemulsification with the use of intracameral epinephrine 5 eyes showed iris billowing, 4 eyes presented some extent of miosis and 2 eyes had tendency to iris prolapse. There were no serious intraoperative complications. CONCLUSIONS Intracameral epinephrine without the addition of lidocaine was efficacious in the management of IFIS in patients on tamsulosin.

Abstract
AIM The aims of the study were to study: (i) affective temperaments in open-angle glaucoma (OAG) patients with some degree of functional visual impairment; (ii) psychological well-being and perceived disability, and their associations with affective temperaments; and (iii) associations between visual impairment, affective temperaments and psychological well-being. METHOD Participants were 91 outpatients (39 women, and 52 men) with open-angle glaucoma (OAG) who were assessed for Visual Field Index, Mean Defect and Pattern Standard Deviation. Patients were also administered the Beck Hopelessness Scale, the TEMPS-A (Rome), the Gotland Male Depression Scale, the Emotional Well-being Scale, the Perceived Disability Questionnaire and the Suicidal History Self-Rating Screening Scale. RESULTS Open-angle glaucoma patients (compared with a non-clinical sample of university students) had higher scores on the TEMP-A dysthimic and hyperthimic traits and lower scores on cyclothimic, irritability and anxiety traits. Such temperament variability was not linked to differences in severity of glaucoma. We did not find strong evidence supporting the fact that measures of visual impairment were linked to emotional well-being and depression. However, logistic regression analysis revealed that patients may have different patterns related to their illness according to specific temperaments. CONCLUSION Patients with OAG may have different temperament profiles than non-clinical individuals. Such categorisation may be useful for predicting how they face the illness, for providing better care as well as for early recognition of mood disorders symptoms.

Abstract
Volkamer lemon (Citrus volkameriana Ten. & Pasq., Rutaceae family) is the most commonly used rootstock for some ornamental citrus (oval kumquat and calamondin), improving the aesthetic quality of the plants and their marketable value. During the winter of 2011, symptoms of stem blight were observed on approximately 10% of 12,000 1-year-old potted C. volkameriana seedlings grown in different blocks in a commercial nursery near Catania (eastern Sicily, Italy). In the same nursery, only 1% of 15,000 older seedlings (2-year-old) showed disease symptoms. Initial symptoms included gray lesions on stems and occasionally on twigs. Later, buff lesions and gum exude appeared. Symptomatic stems and twigs were usually girdled and killed. In the lesions, irregular, dark gray sclerotia (1.0 to 5 × 1.0 to 7.0 mm, average 2.5 × 3.9 mm) were produced. In high relative humidity, cottony, white mycelia on the bark surface of infected tissues were also observed. Isolations were performed by transferring approximately 300 fragments of symptomatic tissues from 15 C volkameriana seedlings, surface-sterilized with 1% NaClO for 1 min, on potato dextrose agar (PDA) amended with 100 mg/liter of streptomycin sulfate. Sclerotinia sclerotiorum (Lib.) de Bary was recovered from all infected plants. Colony type, morphology, and dimensions of sclerotia were examined on PDA at 22 ± 1°C after 10 days in the dark. Sclerotia produced on PDA measured 2.0 to 7.0 × 1.5 to 4.0 mm (average 5.6 × 2.6 mm). DNA isolation was performed with the DNA Purification Kit (Puragene-Gentra, Minneapolis, MN) following the manufacturer's instructions. Amplification and sequencing of the internal transcribed spacer (ITS) region of rDNA was performed with primers ITS1/ITS4 (2). BLAST analysis of the 550-bp segment showed a 98% homology with S. sclerotiorum strain ms85 (GenBank Accession No HQ833450.1), thus confirming identification based on morphology. Koch's postulates were fulfilled by pathogenicity tests carried out on 20 1-year-old potted C. volkameriana seedlings. Each seedling was inoculated with five mycelial agar plugs (6 mm in diameter) and five sclerotia from the edge of 10-day-old colonies on PDA and placed in wounds made with a sterile blade in the bark of stem and twigs. Inoculated wounds (10 for each plant) were wrapped with Parafilm. The same number of control plants were wounded and inoculated with sterile PDA plugs. All inoculated plants were incubated in a growth chamber at 22°C with 80 to 90% relative humidity for 14 days. Blight symptoms and lesions on the stem and twigs identical to those observed in the nursery developed on all plants with both types of inoculum. Noninoculated control plants remained symptomless. S. sclerotiorum was reisolated from all symptomatic tissues and identified by morphology as previously described, completing Koch's postulates. To our knowledge, this is the first report of S. sclerotiorum stem and twig blight on C. volkameriana. Worldwide, Sclerotinia stem and twig blight is considered a minor disease on citrus (1), but this evidence suggests that in eastern Sicily, S. sclerotiorum may be an important pathogen of young C. volkameriana seedlings in nurseries.

Abstract
The authors present a case of disseminated Kaposi's sarcoma in a male patient, HIV negative and Hepatitis C virus (HCV) positive. Although it is well-known that in HCV positive patients the onset of cutaneous diseases such as porphyria cutanea tarda, mixed essential cryoglobulinemia, lichen planus, polyarteritis nodosa, itch/prurigo, is possible, papers on its association with disseminated Kaposi's sarcoma in HIV negative patients are rare in the literature. Such an association is probably not a matter of chance: in fact, the changes to the immune system induced by the HCV virus, in synergy with those induced by the Human Herpetic virus-8, could likewise play a role in the development of Kaposi's sarcoma as happens in patients with immunodeficiency .

Abstract
This case report is about a 4-year-old patient with a IIA2 ''Y-type'' duplication, with the accessory urethra arising from the anterior orthotopic urethra and exiting in perineal-scrotal position, in association with posterior urethral valves (PUV). Cystourethroscopy through the ventral urethra revealed a type III urethral valve (diaphragm) and this was fulgurated. Duplicated dorsal urethra was excised surgically. Postoperative period was uneventful. This case is unique, because it shows PUV in a child with a very rare type of ''Y-type'' duplication. The presence of PUV in patients with urethral duplication is probably not an incidental finding but, to date, embryology of this rare association is not known.

Abstract
PURPOSE To make a visual field retrospective analysis on a group of patients with primary open angle glaucoma (POAG) and to evaluate whether different refractive errors could have different progression of the 30 degrees central sensitivity. METHODS A total of 110 patients with POAG (52 men and 58 women) were included in the study. All the patients were divided into four subgroups based on the refractive error. The visual field of all the included patients was assessed by an Octopus 30 degrees central visual field every 6 months, for a total of 837 visual fields examined. The resulting data were analyzed by PERIDATA for Windows 1.7 TREND function. Mean defect (MD) and loss variance (LV) were considered for the analysis. RESULTS At the first examination, 82% of eyes showed a global decrease of differential light sensitivity (MD >2 dB) and in 67% the distribution of the defect was nonhomogeneous (LV >6 dB). The analysis of variance for subgroups showed a more significant decrease of MD in highly myopic patients. A linear regression analysis highlighted a statistically significant change in time of MD in 36% and of LV in 34% of the eyes studied. Highly myopic patients had the highest (p<0.01) percentage of change of MD and LV (46% and 42%, respectively). Among the four subgroups, there was no difference in progression of MD decrease in time. CONCLUSIONS These results showed that after 5 years of glaucoma, the visual field was altered in most of the eyes examined (82%) and that in 67% of cases, its defect was nonhomogeneous and worsened with the increase of myopia. The regression linear analysis of visual field changes in time showed a progressive increase of MD and LV in approximately one third of all the eyes examined.

Abstract
Despite the efforts made, a serum marker reliable for the screening and follow-up of patients with gastric cancer has not yet been identified. The aim of this preliminary study was to test the role of pro-inflammatory cytokines interleukin 1beta, interleukin 8 and tumour necrosis factor alpha in patients with gastric cancer and in control groups. The statistical analysis of cytokines serum levels in the group with gastric cancer versus control groups has shown considerable differences (p < 0.001) in their mean rates. The results indicate that the cytokines interleukin 1beta, interleukin 8 and tumour necrosis factor alpha might perhaps act as diagnostic markers in patients with gastric cancer. Therefore, it is hypothesized that after more extended trials, their use in the screening and prognostic assessment of these patients could be a possibility.

Abstract
The Authors, on the basis of their experience on the use of self-expanding prostheses in abdominal surgery, report on the use of these prostheses in two patients who, having undergone a gastrectomy for cancer, developed a fistula of the esophago-jejunal anastomosis. Given recent data from literature, using a prosthesis for an anastomotic fistula may be a valid alternative to a second operation, which, apart from obvious difficulties, has a high mortality rate in patients in weakened general health conditions. In these cases, after the application of a stent, excellent results can be obtained and, after some days, the patients can begin a semi-liquid diet, then proceeding to a semi-solid diet, improving quality of life; in addition, within a reasonable time span, after the healing of the fistula, the prosthesis can easily be removed by endoscopy.

Abstract
INTRODUCTION Rectal varices, primitive or secondary to hypertensive or thrombotic disorders of mesenteric-portal circle, represent an uncommon cause of lower digestive bleeding. The presence of rectal varices associated to idiopathic venous portal thrombosis represents a distinct nosologic entity, with important clinical and therapeutic problems related to it. CASE REPORT Patient of young age, with positive anamnesis for primitive rectal varices, admitted to our department for a serious recttorragy. The laboratory underlined moderate anaemia and the endoscopy documented the presence of multiple rectal varices, without evident signs of bleeding; the endoscopy documented the presence of two esophageal small varicose cords F1. The hepatobiliary sonography and the portography showed the massive thrombosis of the portal vein. The new serious episode of rectal bleeding induced us to subject the patient to a surgical operation of Hartmann recto-sigmoid resection. CONCLUSION Because of the slight number of reported cases of primitive rectal varices and because of the scattering of many dates it is difficult to draw an univocal diagnostic and therapeutic algorithm. Clinical framing and subsequent therapeutic approach rise often up from personal experience rather than well defined guidelines. The treatment is controversial, time by time many therapeutic options are reported either conservative or interventionist. The failure of conservative therapy and the recurrent episodes of bleeding give indication to surgical treatment, that is represented by Hartmann colonic resection and/or the porto-systemic shunts in the cases of portal hypertension; in our case we made colonic resection sec. because of lapsed performing status of the patient.

Abstract
BACKGROUND The treatment of acute cholecystitis in the elderly is still a subject of debate, particularly with reference to the timing of surgery and the role of laparoscopy. PATIENTS From January 1994 to June 2002 we observed 27 patients aged over 70 years with acute calcolous cholecystitis. The patients were submitted to ultrasonographic percutaneous cholecystostomy within 12 h of the acute attack. For two patients (7.4%) at high operative risk, we chose a conservative treatment. Twenty-five patients (92.6%) were submitted, in 15 cases (60%) within 5 days and in 10 patients (40%) within 8 days, to a laparoscopic cholecystectomy. Statistical significance was accepted when the value of p was less than 0.05. RESULTS Ultrasonographic percutaneous cholecystostomy was performed successfully in all patients, without major morbidity or mortality, and complete resolution of clinical symptoms was obtained within 48 h. The conversion rate of laparoscopy was 20% (13.3% in patients submitted to surgery within 5 days and 30% in the group submitted within 8 days--p > 0.05). The postoperative morbidity rate was 24%; it was higher (40% versus 15%) in patients converted to laparotomy (p > 0.05); mortality was 4%. The period of hospitalization was 11 days in patients operated laparoscopically and 21 days in those converted to open cholecystectomy (p < 0.001). CONCLUSIONS The more rational treatment of acute calcolous cholecystitis in elderly patients is represented by ultrasonographic percutaneous cholecystostomy followed, within 5 days, by laparoscopic cholecystectomy using an abdominal insufflation maximum to 12 mmHg and a limited 10-15 degrees head-up tilt.

Abstract
AIM The scientific literature contains recent data on the prevalence of blindness and low vision for a few European countries, but most of these studies have been focused exclusively on the elderly sector of the populations. The purpose of the present study was to provide age-specific estimates of the prevalence and causes of visual loss in an Italian population aged 40 years and over. METHODS In total, 847 of the 1,200 citizens >40 years of age (70.6%) in the island community of Ponza underwent complete standardized ophthalmological examinations. Visual acuity (VA) was measured using a standard logarithmic chart. World health organization (WHO) definitions of blindness and low vision were adopted (respectively, VA>1.3 logMAR or a visual field <10 degrees around central fixation, and VA >0.5 to 1.3 logMAR or a visual field <20 degrees around central fixation). Prevalence rates based on presenting VAs were also calculated. RESULTS The overall best-corrected prevalence rates were 0.6% (presenting, 0.8%) for better eye blindness, 2.1% (presenting, 6.7%) for better eye low vision, 1.8% (presenting, 2.6%) for monocular blindness, 5.0% (presenting, 11.2%) for monocular low vision. Cataract, glaucoma, degenerative myopia, and AMD were the main causes of better eye visual loss. CONCLUSION Age-specific prevalence rates in Ponza are fairly consistent with those for other European countries with similar socio-economic conditions and public healthcare systems. A substantial percentage of visual losses remains uncorrected despite the availability of potentially curative therapy. Greater emphasis needs to be placed on educating the public regarding the importance of good vision.

Abstract
The Author's report the case of the simple form of Caroli's disease, a rare malformation, and review literature pointing out the difficulty of an early diagnosis, because disease can be silent for a long time too and it is identified for complication. Today, imaging, endoscopy and interventionist radiology are the most valid tools for a correct diagnosis and treatment, above all in a case of emergency, when other therapeutic solutions are not possible.

Abstract
Ureteral stenting is a routine procedure in endourology. To increase the success rate in difficult cases, it may be helpful to use the rendezvous technique, a combined antegrade and retrograde approach. We performed 16 urological rendezvous in 11 patients with ureteral strictures or urologic lesions. The combined approach was successful in all patients, without morbidity or mortality. In our experience the rendezvous technique increased the success rate of antegrade ureteral stenting from 78.6 to 88.09% (p > 0.05). This procedure is a valid option in case of failure of conventional ureteral stenting.

Abstract
Cystic tumours of the pancreas include a pathologically heterogeneous and rare group of tumours, which however have many common clinical features. They represent about 10% of pancreatic cystic lesions and 1% of all forms of neoplasms, thus having a certain relevance in organ surgery. So far two distinct categories of cystic tumours have been identified, the basically benign serous form and the potentially malign mucinous form, which may sometimes show malignant features as early as the diagnostic stage. As neoplasms are very difficult to interpret before operation, it is essential that diagnosis is as accurate as possible in order to streamline surgery, which will have to be carried out after histological tests have been performed on an adequate number of tumour sections. Basing on these two cases of cystic tumours of the pancreas and on current literature, the Authors discuss the effectiveness of imaging techniques, such as contrast echography, dosage of specific tumour markers and histological tests backed up by immunohistochemistry in identifying these neoplasms, in order to study this rare but interesting pathology more accurately.

Abstract
Fifty-five retrieved tibial inserts with four different locking mechanisms were evaluated for evidence for polyethylene wear between the inferior surface of the tibial insert and metal tray. This type of wear will be referred to as backside wear. Backside wear was assessed by evaluating manufacturer's stamped markings on the inferior polyethylene surface. Because these markings are embossed into the polyethylene surface, they were used as indicators of backside wear. Decreases in the depths of markings indicated that backside wear was clearly evident, regardless of design, in 24 (44%) of the inserts. In eight of these 24 inserts, the manufacturer's stamped markings were removed completely. The amount of polyethylene wear was as a high as 591 mg from the inferior surface. This corresponds to a polyethylene wear rate from the backside of the tibial insert of greater than 100 mg per year, which is two to four times higher than wear rates associated with total hip replacements. The current work provides direct evidence of backside wear in all four tibial insert designs. Backside wear of tibial inserts can be a significant contributor to polyethylene wear in total knee arthroplasty. Close attention should be given to the fixation of tibial inserts to metal trays by manufacturers and surgeons.

Abstract
Moving from the most recent progresses in some address international acts on bioethics of the research, the Convention of human rights and biomedicine and La declaration universelle sur le génome humain e les droits de l'homme, this paper describes the legislative acts which regard many aspects of theoretical and practical scientific research, both in the Italian national and supra-national fields. This legislation concerns mainly the following topics: rights of the human subjects of research, informed consent, privacy on the personal data, activity on organ transplantation, research in genetics, activity in the field of treatment of human gametes and embrios. The author here quotes these legislative acts referring briefly to national and international laws.

Abstract
The spillage of gallstones into the peritoneal cavity from iatrogenic perforation of the gallbladder that occurs during laparoscopic cholecystectomy can result in late and serious complications. We report a case of vesical granuloma with symptoms of dysuria, pollakiuria, and vesical tenesmus that occurred 23 months after a laparoscopic cholecystectomy. Preoperative diagnostic evaluation showed a 3-cm vesical neoformation. A partial cystectomy was performed; macroscopic and histologic examination documented a central nidus of fragmented gallstones and a picture of chronic granulomatous inflammation. Although complications related to unretrieved gallstones that spill into the peritoneal cavity during laparoscopic cholecystectomy are rare, they are being reported with increasing frequency. Therefore, it is important to use tools and techniques that prevent lacerations of the gallbladder and involve retrieval of spilled gallstones.

Abstract
The Longo technique using a circular stapler has changed haemorrhoid therapy. Thanks to the advent of this technique for treating haemorrhoids without excision, we can now successfully eliminate the mechanism responsible for their pathogenesis. The aims of circumferential stapled anoplasty are to correct the anodermal prolapse and restore the haemorrhoidal cushions to their anatomical position. Furthermore, with a few variants the technique can be utilised for other proctological problems, such as obstructed defecation in rectocele and incomplete internal prolapse (or rectal intussusception). The authors report on their experience in a consecutive series of 122 cases undergoing circular stapled anoplasty for haemorrhoids, associated in 10 cases with rectocele or rectal intussuscep-tion, analysing early and late complications after an accurate follow-up. The procedure can be performed with local or spinal anaesthesia. The operation lasted on average 19 minutes. There were few complications: early bleeding (4.9%), late bleeding (0.8%), mild stricture (2.5%) and thrombosis of external piles (8.2%). This new surgical technique is effective and rapid, causes only minimal postoperative pain and could be proposed as an alternative to traditional surgery also in the day surgery setting.

Abstract
Previous classifications of severity for total knee arthroplasty revisions have been based largely on bone loss of the femur and tibia. These approaches failed to address the more technically difficult issues in revision surgery such as surgical exposure, contractures, extremity alignment, implant removal, soft tissue stability (in the anteroposterior and in the sagittal planes), extensor mechanism integrity, and patellar revisability. Through the Knee Society, the authors developed a severity index that incorporated these latter factors into one measure. The current authors describe the application of the Knee Society Index of Severity for failed total knee arthroplasty and its method of scoring.

Abstract
Compared with primary knee replacement, total knee arthroplasty revision surgery is a more complex procedure and accounts for greater expenditures of healthcare resources at each clinical stage. Overall, patients having revision procedures have poorer functional outcomes and higher complication rates than patients having primary arthroplasty. Despite the expanded scope of revision problems and the rapidly emerging technology in revision surgery, the long-term success of any method remains in question. Because there is little consensus on the timing of revision surgery, optimal surgical reconstruction, and the type of prosthesis to be implanted, the Knee Society began development of an Index of Severity for Failed Total Knee Arthroplasty. Fifty-four percent of Knee Society members completed an 82-item questionnaire that determined their clinical impression about potential risk factors for the outcomes of revision surgery for failed total knee replacements. Using these results, a consensus group developed the final version of the index. The result of the nominal group process was the Knee Society Index of Severity, which was based on eight distinct domains. Each domain was divided into attributes and weights based on the questionnaire responses and consensus meeting. Actual case scenarios from five institutions were used to test interrater reliability and validity. The interrater reliability of the average score of all ratings was 0.95; the correlation of the criterion rating with the mean rating was 0.77. When three outliers were not included, the Pearson product correlation increased to 0.92. These data support the application of the Knee Society Index of Severity as a critical component of risk factor studies, effectiveness research, and cost-effectiveness analysis involving revisions of total knee replacements.

Abstract
This article describes the improvement of organ donation and transplantation in Italy during 1995-1999. In 1999, the mean number of donors per million population reached 13.7 in Italy. In addition, an analysis regarding major characteristics of donors and recipients is presented, focusing particularly on donor characteristics that have changed in the past 5 years. Despite the encouraging results, further efforts are required to reach the European mean, which still remains higher than the Italian national mean. In particular, an increase of organ donation and procurement in regions with a poor activity in this field is crucial. A 1999 law on donation and transplantation should help in solving problems that continue to affect part of the nation, especially preparing the healthcare staff dedicated to organ retrieval to promote organ procurement.

Abstract
This paper focuses on the history of the two systems that have been adopted in Italy for the surveillance of Salmonellosis and describes their respective characteristics. Both systems have been subsequently modified: (1) The National Laboratory-based Surveillance System (NLSS) which was created in 1967 for Enteropathogenic Bacteria and subsequently, in 1992, became part of the European computerised Laboratory-based Surveillance System of Salmonellae isolates, the SALM-NET (Salmonella network); (2) The National Infectious Disease Reporting System (NIDRS) which was set up in the 1930s, revised in 1990 and has been used, since 1994, along with the Infectious Disease Informative System (IDIS). The results obtained with the different surveillance systems are presented: (1) The number of isolates from the laboratory surveillance from 1973 to 1997 are described. Total Salmonellae isolates have a slope with an increasing trend from 4372 isolates in 1973 to 15,041 isolates in 1988 drastically dropping to 5479 isolates in 1990 and increasing again to 13,596 isolates in 1993. Attention is given particularly to the epidemiology of S. enteritidis in Italy which increased progressively since 1982 (225 isolates) to 5435 isolates in 1994. S. typhimurium showed a slightly increasing trend in the period 1973-1988 (from 1694 to 3383 isolates) then decreased for reaching again previous levels. S. typhi showed a marked reduction from 573 isolates in 1973 to 33 isolates in 1996. On the contrary, other less frequent serotypes increased. (2) The number of cases of Salmonellosis reported during 1971-1997 are also presented. Other Infections by Salmonellae increased from 12,516 cases in 1976 (renamed Non Typhoidal Salmonellosis in 1990) to more than 20,000 cases in 1992. The number of cases of Typhoid Fever and Infections by S. paratyphi are also described. Particular attention has to be paid to the parallel trends of Salmonellosis using both surveillance systems: number of isolates and number of cases, particularly comparing Other Infections by Salmonellae and total Salmonellae isolates: after the 1992-1993 peak, an initial decrease was observed.

Abstract
The Authors, taking recent literature on tumoral pathology breast studies in to consideration, studied a group of patients with a node or a suspect adenous zone by clinical and instrumental examination with mammoscintigraphy. 22 patients were selected by clinical examination, mammography and ultrasonography. A mammoscintigraphy (Tc 99m Sestamibi) was performed before the surgical operation. The histologic examination revealed 14 cases of breast cancer; 12 of these (86%) resulted positive after scintigraphy, while 2 were false negative. In this study, the scintigraphic exam and its diagnostic accuracy were analyzed, both in relation to anatomical structure of the mammary gland (thick breast, fibrocystic mastopathy, postsurgical scars, etc.) and also in relation to characteristics of the suspected node, the nature of which was not possible to determine from other exams carried out. In conclusion, after comparison between our experience and those reported in literature, we conclude that because of its high specificity and sensibility the mammoscintigraphy exam assumes an important comparative index in obtaining elements for an additional evaluation when other instrumental examinations are dubious.

Abstract
Myogenic gastric tumours are a rare pathology and present difficulties in terms of nosographic classification, which in most cases can be overcome thanks to improvements in imaging and immunohistochemical techniques. Over the period 1995-1999 we observed 5 patients with aspecific dyspeptic symptoms and occasional epigastric pain, suffering from non-epithelial gastric tumours, associated, in one case, with a carcinoma of the stomach. Histological examination of endoscopic biopsies was inconclusive for a definite histopathological diagnosis, while intraoperative biopsies showed the myogenic origin and the absence of morphostructural abnormalities. In the light of these data, we performed three wedge resections, one distal gastric resection and, in the patient with advanced gastric cancer, a D3 total gastrectomy. Histological examination, immunohistochemistry and cytofluorometry enabled us to diagnose stromal tumours with a low risk of malignancy in all cases. At follow-up after 9-54 months all patients are still alive and free of disease. Though the preoperative diagnosis of stromal tumours is possible with endosonography and CT, only histology, immunohistochemistry and cytofluorometry enable us to define the condition nosographically and establish a prognosis with sufficient accuracy to allow correct surgical treatment. A prolonged follow-up is always necessary to identify eventual relapses and/or metastases, which are particularly frequent in the borderline group or in cases with a high risk of malignancy.

Abstract
Allgrove syndrome, rare autosomal recessive pathology, characterized by adrenocortical insufficiency, achalasia and alacrimia, rises usually in pediatric age, while its observation in adults is very rare. A clinical case appeared in an adult, observed by the Authors, is the reason to evaluate the etiopathogenetic mechanisms of this syndrome, with particular attention about potential role of genetic abnormalities and about others factors, again not well known.

Abstract
We report all the first computerised data collected in Italy for the surveillance of Salmonella isolates. Primarily, within the wide framework of the European Community Human Salmonella Surveillance Project (SALM-NET), we report data on the most commonly isolated serotypes in Italy from January 1994 to December 1996. In addition, we report all computerised data historically collected by some Italian regions regarding the period 1980-1993. Total data included in the Italian SALM-NET data base account for 59,336 Salmonella isolates. In the list of the most frequent isolates starting from 1989, S. Enteritidis always ranked first, followed by S. Typhimurium.

Within the wide framework of the European Community Human Salmonella Surveillance Project (SALM-NET), the data on the most commonly isolated serotypes in Italy from January 1994 to December 1996 are reported. The total data included in the Italian SALM-NET data base account for 34,412 Salmonella isolates. In the list of the most frequent isolates, S. enteritidis ranked always first in the years 1994, 1995 and 1996 with 5435 (43.4%), 4589 (37.1%) and 4044 (42.4%), respectively, over the total number of Salmonella isolates. This serotype is followed by S. typhimurium in the list of the top ten isolates, with 2236 (17.9%), 2831 (22.9%) and 2239 (23.5%). The other serotypes included in this list accounted for a much lower number and percentages ranging from 505 isolates of S. derby (4.0%) to 99 isolates of S. brandenburg (0.8%).

Abstract
In this paper we report the distribution of Salmonella Typhi isolates in Italy and their resistance patterns to antibiotics. The data were collected by the Italian SALM-NET surveillance system in a pilot retrospective study of the period 1980-96. Data on drug-resistance were available for 82 isolates out of 176 S. Typhi isolated in Italy. Of these 82 isolates, 32 (39%) were resistant or intermediate to 1 or more antibiotics. Eight isolates were resistant and 7 intermediate to streptomycin; 4 isolates were resistant to ampicillin alone or in association with other antibiotics; only 2 strains (1 isolated in Lombardia in 1993 and the other 1 in Lazio in 1994) were resistant to chloramphenicol, and 2 (isolated in Sardegna and Piemonte in 1995 and 1996, respectively) showed intermediate resistance to chloramphenicol. The strains showing resistance to 3 or more antibiotics were very scarce: 1 (with 5 complete resistances) was isolated in Lazio in 1994, and another 1 (with complete resistance to 10 antibiotics and intermediate resistance to 2 antibiotics) was isolated in Molise in 1988. In conclusion, besides the routine activities to control typhoid fever, an accurate and continuous surveillance is necessary in order to quickly identify multidrug-resistant (MDR) S. Typhi strains and prevent their spread, even though their level, in our country, is still quite low.

Abstract
Carcinoid tumors arise from neuroendocrine system and one of their preferred sites is the appendix. Most of appendiceal carcinoids almost always are clinically silent and are incidentally found at histological examination. For this reason, histological examination of the appendix is recommended in every case of the appendicectomy. Prognostic factors are: tumor stage, histologic pattern and differentiation. The authors present 6 cases of appendiceal carcinoid tumor, clinically silent and found at histologic examination (3 cases of appendicectomy for acute appendicitis, 3 cases of appendicectomy associated with abdominal surgical interventions for other pathology) and compare their experience with the most recent literature on this subject. The conclusion is drawn that the size of this tumor is the main factor that surgeons must consider for the choice of surgical treatment. Incidental, clinical silent, small (less than 2 cm in size) appendiceal carcinoid tumors can be treated by appendicectomy, and they do not need follow-up. Greater (more than 2 cm in size) appendiceal carcinoid tumors, in young patients must be treated with a right hemicolectomy and they need follow-up (periodically radiological, ultrasonographic and endoscopic examinations, tumor markers) because there is the possibility of recurrence or metastases.

Abstract
This paper describes the existing legislation for evaluating the bioethics of clinical trials (drug studies conducted on humans after completion of drug testing on animals). The legislation is presented in chronologic order; thus that of the United States is presented first, followed by a description of the European Union legislation, which includes a brief comment on Italian legislation. The rationale for informed consent and the specific requirements are addressed. Ethical committees are discussed in terms of their membership, responsibilities, and methods of revision. The paper concludes with a comparison between the USA and the European Union legislations.

Abstract
This retrospective investigation attempts to define the incidence of fusion success after postoperative infection after a posterior lumbar fusion, as well as which risk factors may adversely affect arthrodesis after successful debridement. At an average follow-up of 37 months, 18 of 29 patients (62.1%) had a successful arthrodesis. Eighty-seven percent of patients whose fusion excluded the sacrum had a solid arthrodesis, compared with only 36% of those fusions including the sacrum. The fusion rate in female patients was 33.3%, compared with 82.4% in male patients. The rate of fusion with allograft bone was 17.2 versus 83.3% with autograft bone. Female sex, the use of allograft bone, and extension of the fusion mass to the sacrum significantly increase the incidence of nonunion after a postoperative deep spinal wound infection.

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVES To determine the factors influencing symptom relief after uninstrumented posterolateral spinal fusion with or without decompression in adult patients with chronic back pain and previously asymptomatic low-grade isthmic spondylolisthesis. SUMMARY OF BACKGROUND DATA The role of previously asymptomatic low-grade isthmic spondylolisthesis in chronic adult low back pain is unclear. Operative intervention in this setting is controversial. METHODS Twenty-four consecutive adult patients with chronic low back pain and low-grade isthmic spondylolisthesis first detected during routine work-up of new onset low back pain underwent spinal fusion with or without decompression. The influence of active worker's compensation or litigation claims, radicular pain, concomitant laminectomy, age, gender, fusion to L4, intervertebral disc bulge, and pseudarthrosis were investigated. RESULTS All 13 patients involved in worker's compensation claims or pending litigation had fair or poor results. Nine of 11 patients without such issues had good or excellent results. Although the strong association of worker's compensation with poor results made it difficult to assess the importance of other risk factors, the data suggest that good results may be more likely in patients with radiculopathy who undergo laminectomy. CONCLUSIONS This investigation, although limited by a number of factors including small sample size and retrospective, unblinded review, suggests that active worker's compensation and litigation issues are associated strongly with poor results of operative management for chronic low back pain in adult patients with low-grade spondylolisthesis.

Abstract
On occasions when the posterior approach to the upper cervical spine is not feasible, the options provided by a lateral exposure can be invaluable. A case of a nonunited posterior fusion between C1 and C2, with a free-floating posterior C1 arch due to nonhealing of a previous intraoperative C1 ring fracture, is presented to illustrate this point. This 28-year-old man underwent screw fixation between the first and second cervical vertebrae, supplemented with autogenous iliac crest cancellous bone graft, via the lateral approach of Whitesides. The patient's symptoms subsequently resolved, and radiographic evaluation 3 months after the procedure revealed a solid fusion.

Abstract
During 1994, 603 cases of bacterial meningitis were reported in Italy. Seventy-five percent of cases with determined etiology was due to three agents: Neisseria meningitidis (33.4%), Streptococcus pneumoniae (23.4%) and Haemophilus influenzae (18.6%). The majority of cases due to N. meningitidis and H. influenzae occurred in subjects below five years of age (35.7% and 84.8%, respectively) while S. pneumoniae accounted for 52.8% of meningitis cases in subjects older than 44 year of age. The estimated incidence of N. meningitidis on the national population in 1994 was 0.27 per 100,000. Serogroup B accounted for 62.5% of the serotyped isolates, group C for 23.1%, group A for 7.2%, group W135 for 3.6%, group Y for 1.8%. All tested meningococcal strains were susceptible to penicillin as well as to rifampin. Incidence of meningococcal meningitis in 1994 has been low suggesting that its relative importance compared to other bacteria causing meningitis is likely to change in the future. Therefore, extended surveillance on bacterial meningitis by other etiological agents has to be maintained and implemented in order to undertake the appropriate control measures and evaluate their effect.

Abstract
The cases of three patients with a history of paralytic poliomyelitis in childhood who developed the flat back syndrome before or after spinal fusion for degenerative disease as adults were reviewed. The flat back syndrome, a combination of an inability to stand erect because of forward flexion of the trunk and pain in the low back and/or legs, typically occurs in the setting of decreased lumbar lordosis as a result of distraction instrumentation of the spine for scoliosis, vertebral fracture, or degenerative disease. Focus was placed on determining the factors responsible for the development and/or persistence of the flat back syndrome in these patients despite maintenance of, or partial operative restoration of, lumbar lordosis. Considering the essential role that the trunk extensor musculature plays in maintaining upright posture, it may be that a new onset of weakness (postpolio syndrome) in this musculature represents a major contributing factor to the flat back syndrome in these patients. Spine surgeons considering operative procedures in patients with a remote history of paralytic poliomyelitis should be aware of the possible increased risk of the flat back syndrome in this population of patients.

Abstract
To estimate the incidence of Haemophilus influenzae type b (Hib) invasive disease in Italian infants we performed a prospective study in a cohort of newborns enrolled for a randomized trial on safety and efficacy of three pertussis vaccines and followed for onset of serious disease or pertussis. The overall cumulative incidence observed in 15,601 children was 51.3/100,000 for all invasive Hib infections and 38.4/100,000 for Hib meningitis, over 27 months of observation. The incidence density of all invasive Hib disease was 28.7/100,000 person-years, while meningitis occurred with an incidence of 21.5/100,000 person-years. Among the eight cases detected, six were meningitis, one sepsis, and one cellulitis. The child with sepsis died. The incidence and epidemiology of invasive Hib disease in Italy are comparable to those reported from other European countries. Cost-benefit analyses are needed for planning Italian vaccination policy.

Abstract
This report summarizes studies on 1699 foodborne outbreaks, in Italy, reported to the Istituto Superior di Sanità (ISS) (the National Institute of Health of Italy, Rome) during the period 1991-4. The most frequently reported foodborne outbreaks were caused by salmonellae (81%), in particular by Salmonella enteritidis and non-serotyped group D salmonella (34% and 33% of the total salmonella outbreaks, respectively). A vehicle was implicated in 69% of the salmonella outbreaks; eggs were implicated in 77% of the outbreaks for which a vehicle was identified or suspected. Salmonella strains isolated in 54 outbreaks were studied for phenotypic and genotypic characteristics. The isolates belonged to S. enteritidis (50 outbreaks), S. typhimurium (three outbreaks) and S. hadar (one outbreak). In the S. enteritidis outbreaks, phage type 4 was most frequently isolated (64.8%), followed by phage type 1 (14.8%). The virulence plasmid of 38 megadaltons was found in many different phage types of S. enteritidis.

Abstract
Retinal involvement has been documented in a number of patients with pigment dispersion syndrome, which also appears to be associated with a higher than normal risk of retinal detachment. We studied 24 patients with this syndrome to determine the prevalence of lattice degeneration and other retinal disorders associated with a predisposition to detachment. Lattice degeneration was found in 8 of 24 patients examined, with a prevalence that is significantly higher than that reported for normal subjects. Four eyes presented areas of retinoschisis and only one displayed a rhegmatogenous detachment. A father and son (both myopes) were found to have similar lattice lesions in the same retinal quadrants. These findings suggest that pigment dispersion syndrome may be associated with developmental anomalies that are not restricted to the anterior chamber but involve other portions of the bulb as well.
