An Italian multicenter retrospective real-life analysis of patients with brain metastases from renal cell carcinoma: the BMRCC study.

BACKGROUND: The treatment of patients with brain-spread renal cell carcinoma (RCC) is an unmet clinical need, although more recent therapeutic strategies have significantly improved RCC patients' life expectancy. Our multicenter, retrospective, observational study investigated a real-world cohort of patients with brain metastases (BM) from RCC (BMRCC). PATIENTS AND METHODS: A total of 226 patients with histological diagnosis of RCC and radiological evidence of BM from 22 Italian institutions were enrolled. Univariate and multivariate models were performed to investigate the impact of clinicopathological features and multimodal treatments on both overall survival (OS) from the BM diagnosis and intracranial progression-free survival (iPFS). RESULTS: The median OS from the BM diagnosis was 18.8 months (interquartile range: 6.2-43 months). Multivariate analysis confirmed the following as positive independent prognostic factors: a Karnofsky Performance Status >70% [hazard ratio (HR) = 0.49, 95% confidence interval (CI) 0.26-0.92, P = 0.0026] and a single BM (HR = 0.51, 95% CI 0.31-0.86, P = 0. 0310); in contrast, the following were confirmed as worse prognosis factors: progressive extracranial disease (HR = 1.66, 95% CI 1.003-2.74, P = 0.00181) and only one line of systemic therapy after the BM occurrence (HR = 2.98, 95% CI 1.62-5.49, P = 0.029). Subgroup analyses showed no difference in iPFS according to the type of the first systemic treatment [immunotherapy (IT) or targeted therapy (TT)] carried out after the BM diagnosis (HR = 1.033, 95% CI 0.565-1.889, P = 0.16), and revealed that external radiation therapy (eRT) significantly prolonged iPFS when combined with IT (10.7 months, 95% CI 4.9-48 months, P = 0.0321) and not when combined with TT (9.01 months, 95% CI 2.7-21.2 months, P = 0.59). CONCLUSIONS: Our results suggest a potential additive effect in terms of iPFS for eRT combined with IT and encourage a more intensive multimodal therapeutic strategy in a multidisciplinary context to improve the survival of BMRCC patients.

Analysis of risk factors associated with gas embolism and evaluation of predictors of mortality in 482 loggerhead sea turtles.

Sea turtles that are entrapped in static and towed nets may develop gas embolism which can lead to severe organ injury and death. Trawling characteristics, physical and physiologic factors associated with gas-embolism and predictors of mortality were analysed from 482 bycaught loggerheads. We found 204 turtles affected by gas-embolism and significant positive correlations between the presence of gas-embolism and duration, depth, ascent rate of trawl, turtle size and temperature, and between mortality and ascent time, neurological deficits, significant acidosis and involvement of > 12 cardiovascular sites and the left atrium and sinus venosus-right atrium. About 90% turtles with GE alive upon arrival at Sea Turtle Clinic recovered from the disease without any supportive drug therapy. Results of this study may be useful in clinical evaluation, prognostication, and management for turtles affected by gas-embolism, but bycatch reduction must become a priority for major international organizations. According to the results of the present study the measures to be considered to reduce the catches or mortality of sea turtles for trawling are to be found in the modification of fishing nets or fishing operations and in greater awareness and education of fishermen.

Chemical signature of colorectal cancer: case-control study for profiling the breath print.

BACKGROUND: Effective screening for colorectal cancer can reduce mortality by early detection of tumours and colonic polyps. An altered pattern of volatile organic compounds (VOCs) in exhaled breath has been proposed as a potential non-invasive diagnostic tool for detection of cancer. The aim of this study was to evaluate the reliability of breath-testing for colorectal cancer screening and early diagnosis using an advanced breath sampler. METHODS: The exhaled breath of patients with colorectal cancer and non-cancer controls with negative findings on colonoscopy was collected using the ReCIVA® Breath Sampler. This portable device is able to capture the alveolar breath fraction without environmental contamination. VOCs were desorbed thermally and analysed by gas chromatography-mass spectrometry. The discriminatory ability of VOCs in detecting colorectal cancer was evaluated by receiver operating characteristic (ROC) curve analysis for each VOC, followed by cross-validation by the leave-one-out method, and by applying stepwise logistic regression analysis. RESULTS: The study included 83 patients with colorectal cancer and 90 non-cancer controls. Fourteen VOCs were found to have significant discriminatory ability in detecting patients with colorectal cancer. The model with the diagnosis of cancer versus no cancer resulted in a statistically significant likelihood of discrimination of 173·45 (P < 0·001), with an area under the ROC curve of 0·979. Cross-validation of the model resulted in a true predictive value for colorectal cancer of 93 per cent overall. Reliability of the breath analysis was maintained irrespective of cancer stage. CONCLUSION: This study demonstrated that analysis of exhaled VOCs can discriminate patients with colorectal cancer from those without. This finding may eventually lead to the creation of a smart online sensory device, capable of providing a binary answer (cancer/no cancer) and directing to further screening.

ANTECEDENTES: Un cribaje efectivo del cáncer colorrectal (colorectal cáncer, CRC) puede reducir la mortalidad mediante la detección precoz de cáncer/pólipos del colon. La identificación de un patrón de compuestos volátiles orgánicos (volatile organic compounds, VOCs) en el aire espirado se ha propuesto como un procedimiento potencial de diagnóstico no invasivo para la detección del cáncer. El objetivo de este estudio fue evaluar la factibilidad del test de la respiración para el cribaje del CRC y diagnóstico precoz empleando un equipo avanzado de muestreo del aliento. MÉTODOS: Se recogieron muestras de aire espirado de 83 pacientes con CRC y de 90 controles sin cáncer con colonoscopia negativa empleando el ReCIVA Breath Sampler©. Este equipo portátil es capaz de capturar la fracción de aire alveolar espirada ausente de contaminación ambiental. Los VOCs fueron aislados térmicamente y analizados mediante cromatografía de gases acoplada a espectrometría de masas. La capacidad discriminatoria de los VOCs para detectar pacientes con CCR se evaluó mediante un análisis de la curva ROC para cada VOC seguida de validación cruzada mediante el método ir eliminando paso a paso cada uno de los VOCs en un modelo de regresión logística. RESULTADOS: Se observó que 14 VOCs tenían habilidad discriminatoria significativa para la detección de pacientes con CRC. El modelo con el diagnóstico de cáncer versus no cáncer mostró una probabilidad estadísticamente significativa de 151,03 (P < 0,0001) con un área bajo la curva (area under the curve, AUC) de 0,963. En la validación cruzada del modelo se obtuvo un valor global predictivo verdadero para el CRC del 92,5%. La fiabilidad del análisis del aire espirado se mantuvo con independencia del estadio del cáncer. CONCLUSIÓN: Este estudio ha demostrado que el análisis de los VOCs en el aire espirado puede discriminar pacientes con CRC de pacientes sin cáncer. Este hallazgo podría ser de ayuda para diceñar un dispositivo sensorial inteligente en línea, capaz de proporcionar una respuesta binaria (cáncer/NO cáncer) y asimismo contribuir a la indicación de una futura colonoscopia.

JAM-A as a prognostic factor and new therapeutic target in multiple myeloma.

Cell adhesion in the multiple myeloma (MM) microenvironment has been recognized as a major mechanism of MM cell survival and the development of drug resistance. Here we addressed the hypothesis that the protein junctional adhesion molecule-A (JAM-A) may represent a novel target and a clinical biomarker in MM. We evaluated JAM-A expression in MM cell lines and in 147 MM patient bone marrow aspirates and biopsies at different disease stages. Elevated JAM-A levels in patient-derived plasma cells were correlated with poor prognosis. Moreover, circulating soluble JAM-A (sJAM-A) levels were significantly increased in MM patients as compared with controls. Notably, in vitro JAM-A inhibition impaired MM migration, colony formation, chemotaxis, proliferation and viability. In vivo treatment with an anti-JAM-A monoclonal antibody (αJAM-A moAb) impaired tumor progression in a murine xenograft MM model. These results demonstrate that therapeutic targeting of JAM-A has the potential to prevent MM progression, and lead us to propose JAM-A as a biomarker in MM, and sJAM-A as a serum-based marker for clinical stratification.

Knowledge, attitudes, and behavior concerning dental trauma among parents of children attending primary school.

BACKGROUND: Traumatic dental injuries occur frequently in children and adolescents. The purpose of the present study is to examine the levels of knowledge and behaviors regarding dental trauma among parents of children attending primary schools in the Apulia region of Italy. METHODS: The study was carried out using an anonymous questionnaire with closed answers distributed to 2,775 parents who were enrolled based on the entire regional school population. Analyses were conducted using the PROC CORRESP (procedure to perform multiple correspondence analysis) and PROC FASTCLUS (procedure to perform cluster analysis). Statistical significance was set at p-value <0.05. RESULTS: A total 15.5% of the sample reported that their children had experienced dental trauma. Overall, 53.8% of respondents stated that they knew what to do in cases of dental injury. Regarding the time limit within which it is possible to usefully intervene for dental trauma, 56.8% of respondents indicated "within 30 minutes". Of the total sample, 56.5% knew how to preserve a displaced tooth. A total 62.9% of parents felt it was appropriate for their children to use dental guards during sports activities. The multivariate analysis showed that wrong knowledge are distributed among all kinds of subject. Parents with previous experience of dental trauma referred right behaviours, instead weak knowledge and wrong behaviours are associated with parents that easily worried for dental events. CONCLUSIONS: This study showed that most parents reported no experience of dental trauma in their children, and half of them did not know what to do in case of traumatic dental injury and they would intervene within 30 minutes, suggesting that dental trauma may trigger panic. However, they did not have the information needed to best assist the affected child. Motivating parents to assume a preventive approach towards dental trauma may produce positive changes that would result an increase of long-term health benefits among both parents and children.

SCCA-IC serum levels are predictive of clinical response in HCV chronic hepatitis to antiviral therapy: a multicentric prospective study.

The combination of pegylated interferon (Peg-IFN) and ribavirin is currently the gold standard therapy in patients with HCV chronic infection. The duration of therapy, as well as the therapeutic dosage, depend on the genotype. Identification of the genotype and rapid virological response (RVR) are widely accepted as the most important predictors of clinical outcome during antiviral therapy but to optimize cost-benefits and to reduce possible side effects, further prognostic factors are needed. Squamous cell carcinoma antigens immunocomplex (SCCA-IC) has been reported to be increased in the serum of patients with liver cancer. In this multicentric prospective study, we investigated the serum levels of SCCA-IC in 103 patients with HCV chronic infection. Serum HCV-RNA was detected before the beginning of treatment, after 4, 12, 24 or 48 weeks, and at week 24 during follow-up. RVR, early virological response and sustained virological response (SVR) were assessed following the international guidelines. SCCA-IC levels were higher in responders (238 AU, interquartile difference 130-556 AU) and decreased significantly to 125 AU (70-290 AU). The mean baseline value in nonresponders was 149 AU (86.5-306.5 AU), but after 4 weeks of treatment the serum levels decreased to 115 AU (80-280 AU): the profile of reduction was different between patients with or without a positive SVR. Logistic regression with SVR as dependent variable identified as significant independent variables: the reduction in SCCA-IC after 1 month (OR = 4.82; 95% CI 1.39-16.67; P = 0.131) and a genotype other than 1 (OR = 0.094; 95% CI 0.21-0.42; P = 0.002); sex and age were also significant factors influencing SVR. SCCA-IC seems to be a reliable independent prognostic marker of therapeutic effectiveness in anti-HCV positive patients undergoing antiviral therapy.

The effects of weight loss due to gastric banding and lifestyle modification on red blood cell aggregation and deformability in severe obese subjects.

OBJECTIVE: To investigate the changes in the aggregation index (AI) and the elongation index (EI), in severe obese subjects (MbObS) undergoing laparoscopic adjustable gastric banding (LAGB). AI and EI are measured by Laser assisted Optical Rotational Red Cell Analyzer (LORCA) and are markers of erythrocyte aggregation and deformability, respectively. DESIGN AND SUBJECTS: Before, 3 and 6 months after LAGB plus lifestyle changes (Mediterranean diet plus daily moderate exercise), we evaluated AI, EI, body mass index (BMI), total (ToT) cholesterol (Chol), high-density lipoprotein (HDL)-Chol, low-density lipoprotein (LDL)-Chol, triglycerides and fasting glucose and insulin levels in 20 MbObS. The Student's t-test was used for comparisons between independent groups and the analysis of variance to assess differences in AI and EI at the 3 time points. Pearson's correlation coefficient was used to assess correlation among continuous variables and multiple linear regression analysis to assess predictive factors for AI and EI changes. RESULTS: BMI and all blood parameters showed a statistically significant decline 3 and 6 months after LAGB as compared with basal, except for EI and HDL-Chol that significantly increased. Stepwise selection of predictors shows that at 3 and 6 months, EI values depended on HDL-Chol values at the same time point. In the EI model, blood glucose was also statistically significant at 6 months. CONCLUSION: Our data show a significant improvement in EI after LAGB-induced weight loss, which correlates with an improved lipid pattern and support the idea that the rapid weight loss induced by LAGB plus lifestyle changes might reduce the thromboembolic risk and the high mortality risk found in MbObS.

Clinical aggressiveness of incidental and non-incidental thyroid cancer.

BACKGROUND: With the increasing use of thyroid ultrasound, the recognition of thyroid nodules in a large proportion of apparently healthy subjects has become common. Because also the papillary thyroid microcarcinomas (PTMC) are being increasingly discovered, it is important to ascertain whether PTMC may exhibit heterogenous clinical features, associated with different aggressiveness. AIM: We retrospectively examined 122 subjects [98 female (80.3%), and 24 male (19.7%)] with thyroid cancer to find potential clinical and pathological findings that could be predictive of clinically aggressive behavior. RESULTS: Twenty of the 31 patients with true incidental cancer (64.5%) in comparison to 20 of the 91 patients with non-incidental cancer (21.9%) had a diameter <10 mm, and this difference was statistically significant (p<0.0001). There was a statistically significant association between size and invasiveness because 19.3% of invasive cancers were <10 mm whereas 44.6% of non-invasive cancers were <10 mm (p=0.005). The relationship between incidental discovery and invasiveness was also evaluated, but the proportion of incidental invasive cancer (19.3%) was not significantly different from that of incidental non-invasive cancer (30.8%). In the multivariate analysis, only size <10 mm (odds ratio=0.35, p=0.013) and papillary vs other histotypes (odds ratio=0.35, p=0.04) were statistically significant protective factors against invasiveness. CONCLUSIONS: a) Incidentally discovered thyroid cancers are more frequently microcarcinomas; b) there appears to be no difference in terms of invasive behavior between incidental and non-incidental thyroid cancer; c) smaller tumor size emerges as a protective factor.

Hospitalisation for COPD in Puglia: the role of hospital discharge database to estimate prevalence and incidence.

BACKGROUND AND AIM: Chronic Obstructive Pulmonary Disease (COPD), although largely preventable, is a great health burden in all the countries worldwide. Statistics of morbidity and mortality of COPD show the need for correct management of the disease. Chronic Obstructive Respiratory Diseases (DRG 88) are in 9th place for discharge in in-patient hospital admission. It is necessary to establish specific indicators which are efficacious and relevant for the patient, the doctor and the health manager. This study will analyse the information in respect of hospital admissions (Hospital discharge database) in Puglia for the period 2000-2005. METHODS: The analysis was carried out utilising the Puglia Region hospital patient discharge database, selecting those patients with admission for chronic respiratory disease as principal or secondary diagnosis. RESULTS: Chronic respiratory diseases are more frequent in males and in people over 45 years old with frequency increasing with age. Geographical distribution shows that there are greater rates of hospitalisation in big cities and in the neighbourhood of industrial areas. Although the trend over time is slight. A higher percentage of re-admission has been found for patients with COPD, and the interval between the two admissions occurs within one or two months; the diagnosis at the second admission is the same as for the first. 10.6% of discharge forms report one diagnosis, especially in patients older than 65 years of age. Little could be said about diagnostic procedures because these are not reported on the discharge form. CONCLUSION: Hospitalisation data confirms expectations regarding age and sex of patients. The high hospitalisation rates indicate that in-patients care still remains the only viable treatment for COPD and other chronic respiratory diseases. The high number of exacerbations reflect the absence of out-patients service or community care, and the same diagnosis in more than one episode shows the lack of efficiency of health services and disease management. This data is necessary to understand disease distribution and the modification of disease management in order to reduce health care costs, to increase efficacy in disease control and to limit repeated exacerbation and so to obtain the maximum benefit for the patients.

Prevalence of atopic symptoms among blood donor carriers of mannose-binding lectin variant alleles.

Mannose-binding lectin (MBL) is a C-type soluble collectin involved in the innate immune response. Carriers of MBL gene variant alleles (MBLva) have decreased plasma concentrations of MBL and increased susceptibility to bacterial and viral infections. The aim of the present study is to test the hypothesis that carriers of MBLva could have a different frequency of atopic symptoms as compared to wild-type carriers. A total of 385 consecutively enrolled Caucasian blood donors were studied. Blood specimens underwent genomic analysis and genotyping for MBLva by polymerase chain reaction (PCR). MBLva carrier status was associated with a reduced frequency of allergic rhinitis (OR 0.41 [95% CI 0.2 to 0.8], chi2 = 6.98, p =.008). No relationship was found between MBLva carrier status and asthma or atopic skin symptoms. MBLva might be one of the host-related genetic factors involved in atopic disorders, namely allergic rhinitis.

Helicobacter pylori seroprevalence in selected groups of Albanian volunteers.

BACKGROUND: Albania is a Mediterranean, South-East European developing country where epidemiological data on infectious diseases are scarce. In this study, the seroprevalence of Helicobacter pylori infection in 1,088 Albanian healthy volunteers (472 females followed-up to a prenatal clinic, 173 recruits, 443 health care workers) was evaluated. MATERIALS AND METHODS: Sera were tested for immunoglobulin-G (IgG) antibodies against H. pylori using a quantitative enzyme immunosorbent assay. RESULTS: The overall H. pylori seroprevalence was 70.7%. The H. pylori seroprevalence increased by age, from 60.4% in individuals younger than 20 years to 81% among those > or = 50 years of age with a significant trend of increase by age. The overall seroprevalence was 73.9% for females and 59.5% for males. In addition the seroprevalence was 55.3% for people living in rural areas and 72.3% for people living in urban areas. No significant differences were found according to level of education except for individuals with elementary level of education. Nurses and hospital auxiliaries have significantly higher H. pylori seroprevalence when compared to other health care workers (physicians and office workers). When each variable (age, gender, area of residence, occupation, and education level) was adjusted for the confounding effect of the other variables by stepwise logistic analysis, we observed that age greater than 40 years and female gender remain the only variables independently associated with the presence of H. pylori IgG antibodies. CONCLUSIONS: H. pylori is highly prevalent among the Albanian population. Improving living conditions, education in hygiene, and the supply of running water are measures to prevent the transmission of H. pylori infection and other infections spread by the fecal-oral route in Albania.

MMP-2, MMP-9, VEGF and CA 15.3 in breast cancer.

BACKGROUND: Matrix metalloproteinases (MMPs) are a family of extracellular matrix degrading proteinases. Owing to their matrix-degrading abilities and high expression in advanced tumours, MMPs were originally implicated in cancer progression, invasion and metastasis. PATIENTS AND METHODS: In this study, the correlation was determined between the expression of gelatinases (MMP-2 and MMP-9) in the sera of breast cancer patients from zymographic analysis and serum concentrations of VEGF and CA 15.3, before surgery and after 1 and 6 months; the association of both markers with clinicopathological features including histological type, stage of disease and estrogen (ER) and progesterone (PgR) receptors status were also analysed. In all, 88 breast cancer patients and 20 healthy women were involved in this study. RESULTS: No statistically significant correlation between pro MMP-2, pro MMP-9, VEGF and CA 15.3 serum levels was found (p>0.05). In breast cancer patients, a significant decrease of the pro MMP-2 serum expression 1 month after surgery with respect to serum levels before surgery (p=0.0008) was evident, as well as of CA 15.3 serum levels at baseline and after 1 month (p=0.017). Moreover a strong decrease of pro MMP-9 serum levels was found in 88 breast cancer patients after 1 month (p=0.028) and after 6 months (p =0.009) from surgery. On the other hand, no significant differences in the serum levels of VEGF, CA 15.3, pro MMP-2 or pro MMP-9 between 88 breast cancer patients preoperatively and 20 healthy women as controls were found. Our findings did indicate a significant positive association between higher preoperative levels of CA 15.3 and progression of disease (p=0.03), as well as a longer disease-free survival in patients who exhibited a decrease of serum pro MMP-9 expression compared to other biomarkers. No relationship between these four markers and the main clinical and pathological parameters was found. CONCLUSION: The present study failed to demonstrate any association between serum levels of MMPs, VEGF and CA 15.3 and well-known clinicopathological characteristics of breast carcinoma, while demonstrating the prognostic value of CA 15.3 and pro MMP-9 in the follow-up of breast cancer patients.

Free triiodothyronine and thyroid stimulating hormone are directly associated with waist circumference, independently of insulin resistance, metabolic parameters and blood pressure in overweight and obese women.

OBJECTIVE: To examine whether obesity, body fat distribution and insulin resistance have an independent effect on serum TSH and free thyroid hormones (FT3 and FT4) in a cohort of euthyroid women, represented by overweight and obese patients. DESIGN AND PATIENTS: A total of 201 women, aged 18-68 years, with body mass index (BMI) > or = 25.0 kg/m(2) and TSH levels < 4.0 mU/l were investigated. MEASUREMENTS: Fasting TSH, FT3, FT4, insulin, glucose, and serum lipid concentrations, and the level of insulin resistance, estimated by the homeostasis model assessment for insulin resistance (HOMA-IR). Waist circumference was measured as an indirect parameter of central fat accumulation. RESULTS: FT3 was directly associated with BMI (P < 0.01) and waist circumference (P < 0.01), and negatively correlated with age (P < 0.001). FT4 was negatively associated with HOMA-IR (P < 0.05) and fasting insulin levels (P < 0.05). TSH was positively correlated with waist circumference (P < 0.05) and negatively associated with age (P < 0.05). When multiple regression analysis was performed with FT3 as the dependent variable, and waist circumference, HOMA-IR, blood pressure levels and serum lipid concentrations as independent variables, FT3 maintained an independent association only with waist circumference (positive, P < 0.05) and age (negative, P < 0.001). When multiple regression analysis was performed with TSH as the dependent variable, and the above parameters as independent variables, TSH maintained an independent association only with waist circumference (positive, P < 0.05) and age (negative, P < 0.05). By contrast, when multiple regression analysis was performed with FT4 as the dependent variable, FT4 did not maintain an independent association with any of the independent parameters. CONCLUSIONS: Progressive central fat accumulation is associated with an increase in both FT3 and TSH serum levels, independently of insulin sensitivity, metabolic parameters and blood pressure. These results suggest that (1) progressive central fat accumulation is associated with a parallel increase in FT3 levels, possibly as an adaptive thermogenic phenomenon, and (2) the control of TSH secretion by free thyroid hormones is possibly impaired in obesity.

Endometriosis is characterized by an impaired localization of laminin-5 and alpha3beta1 integrin receptor.

Endometriosis is an estrogen-correlated benign disease characterized by a marked ability of endometrial-like cells to invade and proliferate outside uterine cavity, resembling for some invasive aspect the cancer growth. The molecular mechanisms regulating endometrial cell invasiveness are mostly unknown, although interactions between extracellular matrix (ECM) proteins and their transmembrane receptors, integrins, are likely to play a central role. In particular, laminin (Ln)-5 could be closely involved, as it is in cancer. We have investigated the expression of Ln-1, Ln-5, and collagen IV (Coll IV) ECM proteins and their receptors, alpha3beta1 and alpha6beta4 integrins, in atrophic, proliferative, and secretive endometrium and in endometriosis. The results show that Ln-5, but not Ln-I and Coll IV, is altered in secretive endometrium as well as in endometriosis tissues. No alterations are observed in atrophic or proliferative endometrium. Consistently, the polarization of both integrin subunits alpha3 and beta1, but not alpha6 and beta4, is altered in secretive endometrium and endometriosis tissues, but not in atrophic and proliferative endometrium. These results seem to suggest that Ln-5 and alpha3beta1 could be involved in the invasive mechanism of endometriosis. The altered expression of Ln-5, by upregulating matrix metalloproteases activity, suggest an invading process similar to that of many cancer processes.

Intestinal parasites in healthy subjects in Albania.

The purpose of this study was to evaluate the prevalence of intestinal parasites in 277 healthy subjects in the city of Mamuras (Albania, South Eastern Europe) and the correlation between parasitic infections and possible risk factors. Faecal samples collected with sodium-acetate-formalin fixative were concentrated by formalin ethylacetate sedimentation and examined as wet mounts, permanent stains and by anti-Giardia/Cryptosporidium fluorescent antibodies. Data concerning age, sex, level of education, availability of piped water, number of people living in the same house, and residence in rural or urban area were collected for each subject. Statistical analysis was performed by chi-square test and regression logistic analysis. The overall prevalence of intestinal parasites was 183/277 (66.06%). In particular, pathogenic protozoa or helminths were found in 67 subjects (24.18%), including Trichuris trichiura in 34 (12.27%), Giardia duodenalis in 31 (11.19%), Hymenolepis nana in 5 (1.8%), Ascaris lumbricoides in 3 (1.08%). A significant correlation was observed only between parasite colonization and older age and between Trichuris trichiura infection and residence in rural areas.

Drinking habits and performance in an attention test in young people frequenting discotheques.

Throughout July and August 2002, at the same time as a campaign on driving safety, questionnaire and breath alcohol tests was submitted to young people outside the best-frequented discotheques of the Apulia area (Italy), to describe the role of alcohol intake in the evening-time amusement and assess its influence on their attention level. 217 young people, aged between 18-30 years, accepted to fill in a questionnaire, and undergo a 'breathalizer' test and attention test, before and after having spent time in the discotheque. The score difference between entry and exit on the attention test was -1.48 points and alcohol blood level increase up to 0.14 g/l. Established the lower reference limit for the attention test to be 21 points, it was found that 9.7% had an attention score lower than the reference limit, and 61.9% of this group had a blood alcohol level higher than 0.5 g/l. A linear regression model between the difference of blood alcohol level before and after the time spent in the discotheque and attention score on exiting from it, turned out to be statistically significant. It's necessary to go on with continuous police checks and informative awareness campaigns regarding alcohol use, driving and night amusement.

Cisplatin and vinorelbine as neoadjuvant chemotherapy in locally advanced cervical cancer: a phase II study.

Fifty eight consecutive untreated patients with locally advanced cervical carcinoma (LACC) received neoadjuvant chemotherapy (NACT) with cisplatin (CDDP) 80 mg/sqm (day 1) + vinorelbine (VRL) 25 mg/sqm (day 1 and 8). Three cycles of chemotherapy were planned every 21 days. Within 28 days from the completion of chemotherapy patients in complete or partial response were submitted to radical hysterectomy with pelvic lymphadenectomy. On 155 cycles, hematologic toxicity was mild (G3-4 neutropenia and anemia occurred in 16% and 5%, respectively). Forty-seven patients (81%) were submitted to radical surgery; eight (14%) patients were deemed ineligible for surgery because of poor response to treatment, two (3%) for anesthesia contraindications and one (2%) refused surgery. At pathologic examination 12 patients (25%) had a complete response, one (2%) in-situ carcinoma, six (13%) residual microinvasive disease, and 28 (60%) a partial response. None had extracervical disease. Eight patients (14%) had microscopic lymph node metastases. The number of cycles administered was significantly associated with a good pathologic response. Association of CDDP and VRL as NACT in LACC appears safe and effective. Low cost and modest toxicity would support the initiation of a multicenter randomized phase III trial to compare this association with cisplatin alone.
