[The relationship between mobbing and depression syndrome in the female working population of service industry: the problem statement and the prevention strategies in Sicilian environment]. / Rapporto tra mobbing e sindrome depressiva nella popolazione lavorativa femminile del terziario avanzato: dimensione del problema e strategie di prevenzione nella realtà Siciliana.

The concept of "work" and the social interactions in the workplace contribute to develop the working satisfaction and the social and personal identity of the adult. The aim of the survey is that of checking up on the presence of a statistically significant relation between The Depression Syndrome and The Mobbing Phenomenon. It is necessary to understand and value if and how some of the employer's behaviours could have a heavy influence on the worker's psychophysical condition, up to causing a state of anxiety and depression. It has been used the now famous "LIPT" (Leymann Inventory of Psychological Terror), elaborated by Leymann at the beginning of the 90's. It is a short anonymous questionnaire recognized all over Europe as a standard to confirm the Mobbing existence in organizational contexts. The current version of the questionnaire is called "LIPT EGE", a more suitable tool to check the seven parameters of the Mobbing determination, as well as the quantification of the consequent harm. Some scales for depressive symptoms evaluation have been added to the Mobbing questionnaire: The Self Rating Depression Scale (SDS) and The Depression Status Inventory (DSI) of Zung. The questionnaires are administered to 500 workers women in public and private corporation in Sicily, exactly in Siracusa and Catania provinces. 206 women aged 34-50 have answered the questionnaires. In addition to the age and the sex, the distinction variables of the examined people are the position in the firm, nationality, vocational qualification, and the yearly gross income. The research has begun in july and has continued on august 2006. Attention has been focused only on the administrative sectors. Through the chi2 test and the exact Fisher test, the dependence between the changeable presence of depression in the two questionnaires (Zung 1 and Zung 2) and every single variable of the questionnaire on the Mobbing has been pointed out. In particular, the results establish a connection between the presence of depression and systematic isolation, and depression and the changes in the working tasks. The survey has pointed out the working conditions that may lead to Mobbing situations and to psychological frustration; it follows that the Mobbing prevention is a key element if you want to better working life and avoid social emargination.

Kidney transplantation from donors with viral B and C hepatitis.

INTRODUCTION: The success of renal transplantation as a treatment for end-stage renal disease has created a chronic shortage of donor organs. We present our experience in transplanting kidneys from donors with hepatitis B virus (HBV) or hepatitis C virus (HCV) among matched serology-positive recipients. MATERIALS AND METHODS: From January 2002 to November 2005, 44 patients with end-stage renal disease and HCV seropositivity underwent kidney transplantation. In 28 transplants in HCV+ recipients, the donor was HCV+ (DC+/RC+) and in 16 of these cases the donor (one living donor) was HCV- (DC-/RC+). In the same period 14 patients with HBV infection and HbsAg seropositivity underwent kidney transplantation: eight received their graft from a cadaveric HbsAg-positive donor (DB+/RB+), while six patients received their graft from an HbsAg-negative donor. RESULTS: Viral reactivation was higher among DC+/RC+ (21.4%) than DC-/RC+ patients (6%). Graft survivals were 90% and 88% for DC+/RC+ and DC-/RC+, respectively; patient survivals were 100% for DC+/RC+ and 94% for DC-/RC+. Among the group of DB+/RB+, all the patients developed an HBV-DNA positivity in the early postoperative period. Patient and graft survivals were 100% in both groups. CONCLUSIONS: Our results suggest that HBV- and HCV-positive donors can be considered as an alternative donor source, because their kidneys are allocated to the matched serology-positive recipients, shortening their time on the waiting list.

Caspofungin in the treatment of azole-refractory esophageal candidiasis in kidney transplant recipients.

BACKGROUND: Infection is a common cause of morbidity and mortality in kidney transplant recipients. The incidence of esophageal and urogenital candidiasis in kidney and kidney-pancreas transplant recipients has not been well documented. Azoles are safe, effective agents to treat esophageal candidiasis. However, resistance to azoles is now becoming common. This study reports the use of caspofungin for the treatment of azole-resistant esophageal and urogenital candidiasis in kidney transplant recipients. PATIENTS AND METHODS: The incidence of esophageal and urogenital candidiasis was evaluated among 140 kidney transplantations and four combined kidney-pancreas transplants performed over a 2-year period. RESULTS: Twenty-two patients (15.7%) presented with esophageal candidiasis, while seven patients (5%) showed urogenital candidiasis. Thirteen patients with esophageal candidiasis (59%) and four patients (57%) with urogenital candidiasis did not improve after a week of azole treatment. A regimen of caspofungin was started in these patients, who tolerated the treatment. Urogenital candidiasis recurred in two patients 2 and 3 months after the treatment. One patient with esophageal candidiasis did not improve with caspofungin and was switched to amphotericin B therapy. There were no other recurrences of candidiasis among patients treated with caspofungin for a median follow-up of 8 months. CONCLUSIONS: Renal transplant patients remain at high risk for fungal infections. Although the number of patients was limited, the results of this study indicated that caspofungin is an effective, well-tolerated alternative for difficult-to-treat, azole-resistant candida infections in kidney and pancreas transplant recipients. The high costs of the drug limit the use of caspofungin as first-line antifungal therapy, reserving its use to recipients who had undergone unsuccessful azole therapy.

Kidney transplantation from cadaveric donors unsuitable for other centers and older than 60 years of age.

INTRODUCTION: The demand for kidney transplants and the improvement in recipient outcomes over the last years have stimulated surgeons to expand the criteria for usable donor organs, by accepting older patients to expand their donor pool. We herein report our experience with kidney transplants from donors aged older than 60 years, who have been declined by other transplantation centers. PATIENTS AND METHODS: Sixty kidney transplantations were performed with grafts procured from donors aged older than 60 years. Forty-five patients received a single kidney graft (SKG) and 15 received a dual kidney graft (DKG). Mean donor age was 62 years for SKG and 64 years for DKG. Double kidney transplantations were performed with the ipsilateral allocation of both grafts. RESULTS: No primary graft nonfunction occurred. Delayed graft function was observed in 22 SKG (48.8%) and in 7 DKG (46.6%). Acute rejection rates were 9% for SKG and 0% for DKG. One-year patient survival rates were 95% and 100% for SKG and DKG, respectively. Mean serum creatinine levels at 1-year posttransplantation were 1.9 mg/dL for SKG and 1.3 mg/dL for DKG. There were no surgical postoperative complications and mortality. Death censored 1-year graft survival rate was 88% for SKG and 94% for DKG. CONCLUSIONS: Our experience with marginal donors who have been declined by other transplantation centers has demonstrated that such organs, with accurate selection criteria, could be safely allocated to elderly recipients with no increase in postoperative complications, guaranteeing satisfactory results in the short and medium term, allowing a significant improvement in the number of transplants.

Kidney transplantation from hepatitis B surface antigen-positive donors into hepatitis B surface antigen-positive recipients: preliminary findings.

INTRODUCTION: The success of renal transplantation as a treatment for end-stage renal disease has created a chronic shortage of donor organs. We present our initial experience in transplanting kidneys from hepatitis B surface antigen (HbsAg)-positive donors into HbsAg-positive recipients. MATERIAL AND METHODS: From January 2002 to March 2004, 5 patients with end-stage renal disease, hepatitis B virus (HBV) infection, and HbsAg seropositivity underwent a kidney transplantation from a cadaveric HbsAg-positive donor. The median time on the waiting list was 8 months, compared with the median of 3 years on the national waiting list. RESULTS: One patient experienced an acute rejection; 1 patient had an increase in serum level of aspartate aminotransferase (AST)/alanine aminotransferase (ALT) with no signs of recurrence of hepatitis. Graft and patient survival at a median follow-up of 12 months was 100%. CONCLUSIONS: Although the number of patients is small and the follow-up is short, our results suggest that HbsAg-positive donors can be considered as an alternative donor source because their kidneys are allocated to the matched serology-positive recipients, shortening their time on the waiting list.

Kidney transplantation from hepatitis C virus-positive donors into hepatitis C virus-positive recipients: a safe way to expand the donor pool?

INTRODUCTION: Because the disparity between the number of patients waiting for kidney transplants and the number of available cadaveric renal allografts continues to increase, there is a clear need to review the inclusion criteria for cadaveric donors. PATIENTS AND METHODS: From January 2001 to March 2004, 24 patients with end-stage renal disease and hepatitis C virus (HCV) seropositivity underwent a kidney transplantation. In 10 transplants in HCV-positive recipients, the donor was HCV-positive (D+/R+) and in 14 cases the donor (1 living donor) was HCV-negative (D-/R+). RESULTS: Two of 3 HCV-RNA-negative recipients who received a HCV-RNA+ kidney became HCV-RNA+ in the posttransplantation period. There was a low rate of acute rejection (8.3%). One D+/R+ patient experienced an acute vascular rejection, which finally resulted in graft loss, due to the resurgence of severe infectious disease. The serum creatinine levels at 6 months posttransplantation were similar in both groups. Acute liver dysfunction was observed in 1 patient. There was no death in the entire series. Graft survival was 92% and 90% for D+/R+ and D-/R+, respectively.

Use of hepatitis B core antibody-positive donor kidneys in hepatitis B surface antibody-positive and -negative recipients.

INTRODUCTION: The rate of hepatitis B virus transmission via organs from with isolated hepatitis B virus core antibody-positive (HBcAb+) donors in kidney transplant recipients seems very low. PATIENTS AND METHODS: Over 4 years, we performed 36 transplants from Ig HBcAb+, hepatitis B surface antigen (HBsAg)-negative donors into recipients with a history of prior hepatitis B virus (HBV) infection or reported vaccination (28 patients) and in recipients who were not immunized and received a pretransplant prophylaxis with hepatitis B immunoglobulins. We examined the HBV-related outcomes in these 36 patients in comparison with 40 recipients of allografts from HBcAb- donors. RESULTS: No patient receiving an allograft from an HBcAb+ donor developed clinical HBV infection or HBSAg positivity. The rate of seroconversion was 14.2% in immunized patients, 12.5% in nonimmunized patients, and 0% in the control group. The 17.8% of immunized patients developed elevated transaminases after transplant, in comparison with 25% and 10% in the nonimmunized patients and the control group, respectively. Graft and patient survival was 93% and 93% for immunized patients, 100% and 100% for nonimmunized patients, and 98% and 95% for the control group, respectively. CONCLUSION: The use of anti-HBc antibody-positive kidneys was associated with no risk of transmission of HBV infection, without affecting graft and patient survival, and could be considered a safe way to expand the donor pool. Our preliminary results suggest that such kidneys could be safely transplanted even in not immunized patients who underwent a prophylaxis with hepatitis B immunoglobulins.

Ability of recombinant factor VIIa to generate thrombin during inhibition of tissue factor in human subjects.

BACKGROUND: In view of the central role of the tissue factor-factor VIIa pathway in the initiation of blood coagulation, novel therapeutic strategies aimed at inhibiting this catalytic complex are currently being evaluated. A limitation of this new class of anticoagulants may be the lack of an appropriate strategy to reverse the effect if a bleeding event occurs. The aim of this study was to investigate the in vivo potential of recombinant factor VIIa (rVIIa) to induce thrombin generation in healthy subjects pretreated with recombinant nematode anticoagulant protein c2, a specific inhibitor of the tissue factor-factor VIIa complex, in a double-blind randomized crossover study. METHODS AND RESULTS: Administration of nematode anticoagulant protein c2 (3.5 microgram/kg) caused a prolongation of the prothrombin time from 13.7+/-0.6 to 16.9+/-1.2 seconds. The subsequent injection of rVIIa (90 microgram/kg) resulted in an immediate and complete correction of the prothrombin time and a marked generation of thrombin, reflected by increased levels of prothrombin activation fragment F1+2 and thrombin-antithrombin complexes from 0.75+/-0.64 to 3.29+/-6.3 nmol/L and from 2.4+/-0.6 to 10.7+/-3.9 microgram/mL, respectively. Factor X and IX activation peptides showed a 3.5-fold and a 3.8-fold increase, respectively, after the administration of rVIIa in the presence of nematode anticoagulant protein c2. CONCLUSIONS: During treatment with an inhibitor of the tissue factor-factor VIIa complex, the infusion of rVIIa resulted in thrombin generation. Our results indicate that rVIIa may be a good candidate as an antidote for inhibitors of tissue factor.

The effect of the administration of recombinant activated factor VII (NovoSeven) on perioperative blood loss in patients undergoing transabdominal retropubic prostatectomy: the PROSE study.

Transabdominal retropubic prostatectomy is associated with significant perioperative blood loss, often requiring blood transfusion. However, the administration of allogeneic blood and blood products may induce serious immunological or infectious complications. Several studies show that recombinant activated factor VII (rFVIIa; NovoSeven, Novo Nordisk A/S, Bagsvaerd, Denmark) induces short-term local hemostasis. This ongoing study will evaluate the safety and efficacy of rFVIIa on blood loss in patients with normal coagulation undergoing retropubic prostatectomy. Thirty-six patients will be randomized to three different dose levels and receive either rFVIIa as a single intravenous bolus dose or saline. Perioperative blood loss will be assessed from blood-volume suction containers and drains. Blood sample analysis, physical examination and electrocardiography will be performed postoperatively. Eighteen patients have enrolled in the study. Blood loss was 630-4455 ml (mean = 1698 ml), while the number of red cell transfusions varied between 0 and 4 units (mean = 0.9 units). None of the patients developed venous thromboembolism. An independent committee performed an interim analysis after patient 12 and identified a positive trend between treatment groups (not statistically significant). Although a single bolus injection of rFVIIa appears to decrease perioperative blood loss safely and effectively, definite conclusions must await study completion.

[Gallbladder motility following intake of mineral bicarbonate-alkaline water. Ultrasonographic assessment]. / Motilità colecistica dopo assunzione di un'acqua minerale bicarbonato-alcalina. Valutazione ecotomografica.

Sonographic measurement of gallbladder volume has allowed us to assay the influence of many substances (hormones, drugs, etc.) on gallbladder kinetics playing a pivotal role in digestive mechanisms. The aim of the present study has been to evaluate the effect of an alkaline bicarbonate water (Donata) on gallbladder emptying. The study was performed in cross-over. Ten healthy volunteers randomly assumed alkaline bicarbonate water or saline (400 ml). Gallbladder volumes were measured by ultrasonography, according to ellipsoid method, before and 15', 30', 45', 60', 90', 120' after water or saline intake. A week later the test was repeated. Gallbladder kinetics was evaluated referring to fasting volume, residual volume, absolute emptying and maximum percent emptied. Student's "t" test for paired data was used for statistical evaluation of the results. Gallbladder volumes were significantly reduced 15', 30', 45' and 60' after alkaline bicarbonate water administration, whereas saline did not induced gallbladder emptying. The present results suggest that Donata water may be employed in order to ameliorate dyspepsia due to biliary dyskinesia, moreover it may play a complementary role in the prevention and in the medical treatment of biliary lithiasis.

Cisapride improves gallbladder kinetics in patients affected with myotonic muscular dystrophy.

Smooth muscle involvement is relatively common in myotonic muscular dystrophy (MMD). The effects of cisapride on gallbladder motor function in myotonic patients have been investigated in 10 alithiasic patients and in 10 healthy volunteers. Gallbladder volumes were measured by ultrasonography in fasting state and 15, 30, 45 and 60 min after milk intake. The patients were treated with cisapride for two months, after which they underwent a second ultrasonographic examination. Gallbladder emptying was slower and less effective in dystrophic patients than in healthy volunteers. Cisapride was found to improve gallbladder kinetics (efficacy of contraction and rate of emptying) in patients affected with myotonic muscular dystrophy.

[Evaluation of the efficacy of bicarbonate-alkaline water action on gallbladder motility]. / Valutazione dell'efficacia di un'acqua bicarbonato-alcalina sulla motilità colecistica.

Physiological gallbladder contraction, delivering bile salts during meals, plays a key role in digestive mechanisms. A bicarbonate-alkaline water (Uliveto) shows a positive effect on gallbladder kinetics: so it may be useful in order to improve dyspepsia due to delayed gallbladder emptying.

Double pylorus: report of two cases and review of the literature.

Double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb; in most cases it is a complication of penetrating ulcer, sometimes it is a congenital abnormality. The prevalence of this rare anomaly ranges from 0.02% to 0.13%; the male:female ratio is about 2:1. Two cases of acquired double pylorus are reported with a review of the literature. The first case represented an occasional report; in the other one the development of double pylorus from confluent prepiloric and bulbar ulcers was documented through serial endoscopies. Both patients were affected with chronic renal failure and referred previous treatment with diclofenac; however, their relationship with double pylorus onset remains unproven.
