ABSTRACT
In the context of a wide healthcare system reorganization, the Abruzzo Region of Italy used the Appropriateness Evaluation Protocol (AEP) to carry out a systematic evaluation of the appropriateness of the admissions performed during 2006 in all public hospitals. After specific training courses, a sample representative of all ordinary admissions was assessed twice: first by regional investigators (external assessment) then by the local personnel (internal assessment). Random-effect logistic regression was used to evaluate potential inappropriateness predictors. On a total of 13081 hospital days (2393 hospitalizations), 39.7% (95% Confidence interval: 38.9%-40.6%) were inappropriate at the regional assessment; 39.5% at the internal assessment, with high correlation between the two controls (K = 0.73). Another 10.4% of admissions, excluded by the evaluation, was assigned to DRGs at high risk of inappropriateness and should be considered. In single hospitals, the inappropriateness ranged between 17.9% and 57.9%, with large variation across wards. Additional significant predictors of inappropriateness were the day and hour of admission and hospital size, with lower inappropriateness in bigger ones. In 2006, there was a large degree of hospital misuse in public hospitals in the Abruzzo Region. The approach used in the survey may have contributed to the drastic reduction of the number of ordinary admissions observed in the Region between 2006 and 2007.

The study was aimed at evaluating whether the degree of hospital admission inappropriateness and timeliness was improved in the Abruzzo Region of Italy between the year 2001 and 2005. All hospital admissions for the year 2001 (n = 286,924) and 2005 (n = 280,761) in the Region were analysed (SDO discharge data), and three diseases were in-depth reviewed: diabetes mellitus; cholecystitis/cholelithiasis; and bacterial pneumonia. Using Disease Staging methodology, the timeliness of hospitalisation was assessed by grouping admissions in three categories: premature or medically unnecessary, timely, and late. Overall, the rate of medically unnecessary admissions for diabetes mellitus was 72.3% in 2001 and 73.4% in 2005. The percentage of late hospitalizations for the same disease was still 20.2% in 2005, when the rate of late admissions for cholelithiasis/cholecystitis was 53.3% (+10.5% compared to 2001);for bacterial pneumonia 14.5%. The rate of early admissions did not improve for any disease, and any of the six local health units in Abruzzo showed an improvement in all the measures evaluated. In the period 2001 and 2005, in the Abruzzo Region there is no evidence of an improvement in the rates of inappropriate hospital admission, both early and late, which are still excessively high for all diseases examined excepted bacterial pneumonia. Interventions to address this issue are strongly needed.

Current epidemiological data suggest that the number of preventive interventions aimed at controlling alcohol, drug, food abuse and smoking achieved only partial success, especially in young individuals. In order to improve preventive action efficacy, the literature suggests the adoption of contents and communication instruments specifically targeted to different groups of individuals. The Valentino Project is a comprehensive survey on the characteristics of abuse of a representative sample of 3000 young workers (aged 18-35 years)from the Abruzzo Region of Italy. This paper describes its main methodological issues and the complete version of the questionnaire HW-80 (Healthy-Worker 80), that will be administered. HW-80 questionnaire includes 80 items on demographic characteristics, self-reported health, job-related stress, work organization, pattern of abuse, physical activity and others, and several of these items have been taken or derived from repeatedly validated questionnaires (SF-12, CAGE, Job-Strain, Effort-Reward, EU-DAP, etc.). The aims of the Valentino Project are to quantify the prevalence of obesity, alcohol use, smoking and drug addiction in diverse typologies of workers, and to describe their pattern of use. The ultimate purpose is to provide the necessary knowledge for the development of preventive strategies targeted to different professions, in order to maximize their efficacy.

BACKGROUND: Pouchitis is a common and troublesome condition, and a disturbed microbiological flora and mucosal blood flow in the pouch have been suggested as possible causes. Laser Doppler flowmetry (LDF) has been used successfully to measure gastric and colonic mucosal perfusion in humans. The aim of this study was to evaluate the effect of intervention with probiotics on ileal pouch inflammation and perfusion in the pouch, assessed by endoscopy, histology, fecal calprotectin and LDF. METHODS: A fermented milk product (Cultura; 500 ml) containing live lactobacilli (La-5) and bifidobacteria (Bb-12) was given daily for 4 weeks to 10 patients operated with ileal-pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). Mucosal perfusion was measured with LDF and the degree of inflammation was examined at predefined levels of the distal bowel by endoscopy and histology. Stool samples were cultured for lactobacilli and bifidobacteria and calprotectin were measured before and after intervention. RESULTS: The LDF measurements were reproducible in the pelvic pouch at each of the predefined levels, but did not change after intervention. The mucosal perfusion was reduced in the distal compared to the proximal part of the pouch. Calprotectin levels did not change significantly after intervention. The median endoscopic score for inflammation was significantly reduced by 50% after intervention, whereas the histological score did not change significantly. CONCLUSION: The results suggest that probiotics primarily act superficially, with change of gross appearance of the mucosa at endoscopy, but without significant effect on histological picture, mucosal perfusion or faecal calprotectin, during a relatively short period of 4 weeks.
ABSTRACT
Several neurotrophic factors have been identified that influence neuronal populations during central nervous system development, maturation, and senescence. To examine the responsiveness of the intact and the lesioned adult mammalian spinal cord to neurotrophic factors, primary rat fibroblasts were genetically modified to produce and secrete human nerve growth factor (NGF). These NGF-producing cells were then grafted to nonlesioned or lesioned adult rat spinal cords for periods of up to 1 year in vivo. Robust outgrowth of sensory and noradrenergic neurites was elicited by grafts in the previously nonlesioned spinal cord. Equally robust growth of sensory and noradrenergic neurites was observed in the lesioned spinal cord; in addition, partial sprouting of local motor neurites was elicited in the lesioned spinal cord. Thus, multiple neuritic populations of the adult spinal cord respond to neurotrophic factors by extending neurites, and this responsiveness is maintained and extended after major injury. Nerve growth factor delivered by somatic gene transfer may be a useful means of promoting axon regrowth in the injured spinal cord.

From January 1, 1991, to October 31, 1993, 67 patients with a histologic diagnosis of benign cystic teratoma were treated by operative laparoscopy in nine centers in Rome. The mean age of patients was 29.7. years, ranging from 16 to 45 years. The mean diameter of the cysts was 41.6 mm, ranging from 20 to 120 mm. The procedures were completed by laparoscopy in 62 cases (92.5%) whereas 5 cases were converted to laparotomy. Conservative treatment was performed in all cases except seven cases (10.44%), where ovariectomy was performed. No recurrences occurred in all patients, with a follow-up of at least 3 months. We conclude that operative laparoscopy can be considered a valid alternative to classic laparotomy for dermoid cysts.
ABSTRACT
The cytogenetic follow-up of a case of refractory anemia with excess of blasts (RAEB) that rapidly evolved to acute myeloblastic leukemia (M1-FAB type) is described. Bone marrow analysis at presentation revealed two chromosomally abnormal clones that shared an interstitial deletion of the long arm of chromosome 5 (5q-) and a terminal deletion of the short arm of chromosome 12 (12p-), but that differed from one another in the localization of a very similar segment of chromosome 17 (i.e. 17q11-12qter) on two clearly distinct karyotypic sites: 2q37 and 17q25. Fourteen percent of the metaphases examined bore the 2q+ marker and 38% the 17q+ marker; the remaining cells had a normal karyotype. A second study carried out 4 months later, at onset of the acute phase, revealed that the clone with normal karyotype had almost completely disappeared and that there had been an inversion in the ratio of the two abnormal cell populations. In the final study, made 1 month before death, the cells with t(2;17) had totally effaced the other clone. These findings seem to indicate that, among the karyotypic changes that occurred in an original clone with 5q- and 12p-, only the t(2;17) could have played a crucial role in the final leukemic transformation.

Two sequential lymph node biopsies taken from a non-Hodgkin lymphoma patient revealed two karyotype abnormalities peculiar to B cell neoplasias: trisomy 12 and t(2;8)(p12;q24) translocation. The first was documented in all cells analyzed, while the second was present in 20% of the metaphases from the first biopsy and in 100% from the second. This suggests that the t(2;8) translocation arose as a secondary karyotypic change. In addition, although immunological characterization of the neoplastic cells disclosed a monoclonal B cell population that expressed immunoglobulin kappa light chains, as usually found in Burkitt's lymphoma with t(2;8) translocation, Southern blot analysis provided evidence of rearrangement in only one kappa chain allele.

Cytogenetic investigation of lymph node-derived cells taken from a peripheral T-cell lymphoma patient revealed an insertion of the segment 11q21q25 into the band p22 of chromosome #6 as the only anomaly. The probable role of the three rearranged chromosomal regions on the development of this neoplasia is discussed.

A phenotypically otherwise normal homosexual man with a 46,XY,inv(2)(q21q33) karyotype inherited from his mother is described. The breakpoints were different from those observed in the only other case of familial paracentric inversion of chromosome 2 reported in the literature, but in our case they seem to correspond to constitutive and aphidicolin-induced fragile sites.

A chronic myeloid leukemia (CML) patient who had presented a t(2;9;22) translocation during the chronic phase developed an unusual t(4;21) (p16;q22) translocation during the M2 type FAB classification blastic crisis. The role of these two recombinant chromosomes in the genesis of the terminal phase is discussed, particularly as the breakpoint on chromosome 21 near to the ets-2 oncogene locus, seems to be the same as that described in the t(8;21) (q22;q22) translocation specific of type M2 AML.

Cytogenetic analysis of bone marrow from a chronic myeloid leukemia patient in chronic phase revealed a classical Philadelphia chromosome from a complex translocation t(2;9;22). The break points on 9 and 22 were, apparently, the same as for the standard translocation (9;22). However, whereas the terminal band of 9 (9q34) was translocated in the usual site, that is on 22q-, the tract deleted from 22 was present on band p13 of chromosome 2. The finding of this rare 22 translocation in classical CML would seem to support the hypothesis that the crucial event in the pathogenesis of CML is the translocation of band 9q34, that contains the c-abl oncogene, onto the Ph' chromosome, rather than the translocation of the tract deleted from 22 to some other chromosome site.
