Communication in NICUs.

In a Neonatal Intensive Care Unit (NICU) counseling should be a shared culture for all the care givers: it should be developed by all the professionals, to face up to parents' needs of information, explanations, facility of decisions, finding of resources, agreement, help, reassurance, attention. The first essential aspect is the training in counseling skills, by periodic courses for all professionals of the department (physicians, nurses, and physiotherapists). In our department, a professional counselor is present, assisting the medical staff in direct counseling. The counselor's intervention allows a better parent orientation in the situation. A more effective sharing of these rules also facilitates the communication among parents and medical staff. Periodic meetings are established among the medical staff, in which the professional counselor discusses difficult situations to share possible communicative strategies. We wanted to have not only a common communicative style, but also common subjects, independent from the characteristics of each of us. Individuals are often faced with different situations. For every setting that we more frequently face in communication (for example the first interview with a parent of a very preterm infant) we have built an 'algorithm' that follows a pattern: (1) information always given; (2) frequent questions from parents; and (3) frequent difficulties in the communication. Counselling is also a tool to face some critical issue, such as the decision to open the department to parents 24 h on 24, or the promotion of mother's milk use in Very Low Birth Weight Infants (VLBWI).

Communicative strategies in a neonatal intensive care unit.

Counseling is a professional intervention based on skills to communicate and to build relationships. The project 'Not alone', related to counseling at our Neonatal Intensive Care Unit, is aimed to let counseling become a 'shared culture' for all the care givers. The first essential aspect is to form the ability of counseling through periodic courses for all professionals of the department (physicians, nurses, and physiotherapists). In our department, a professional counselor is present assisting the medical staff in direct counseling. The counselor's intervention allows a better parent orientation in the situation. A more effective sharing of these rules also facilitates the communication among parents and medical staff. Periodic meetings are established among the medical staff, in which the professional counselor discusses difficult situations to share possible communicative strategies. We wanted to have not only a common communicative style, but also common subjects, independent from the characteristics of each of us. Individuals are often faced with diverse situations. For every setting that we more frequently face in communication (for example the first interview with a parent of a very preterm infant) we have built an 'algorithm' that follows a pattern: (1) information always given; (2) frequent questions from parents; and (3) frequent difficulties in the communication. We also need to record important moments, for instance the 'case history of the communication': in fact it would be desirable to have the case history, a sheet dedicated to important communications that are absolutely to be shared with other professionals.

Serum iron indices as a measure of iron deposits in chronic hepatitis C.

Serum iron indices are believed to be elevated in patients with hepatitis C virus (HCV) infection in connection to the presence of hepatic inflammation, though this hypothesis has never been formally tested. We studied 69 consecutive, unselected anti HCV antibody positive patients, aged 14 to 70 years. Iron, transferrin saturation and ferritin were measured in fasting serum samples. Histologically detectable iron (HDI) as well as histologic grading and staging were estimated semiquantitatively in liver biopsy samples. The median values for serum iron, transferrin saturation and serum ferritin were 24 micromol/l (range, 8-61), 29 percent (range, 6-77) and 170 microg/l (range, 1-954), respectively. At univariate analysis, all three serum iron indices were positively correlated with grading and staging scores, as well as with HDI in the liver; only serum iron was positively correlated with transaminases. At multivariate analysis, independent associations were found between serum iron and the grading score; ferritin and sinusoidal and portal HDI; transferrin saturation and total hepatic HDI. In conclusion, in hepatitis C, serum iron reflects the degree of current hepatic inflammation and necrosis, whereas the extent of progressive deposition of iron in sites of fibrosis is best reflected by serum ferritin. Transferrin saturation is the best predictor of the status of hepatic iron deposits.

Bilateral empyema caused by adult-onset Still's disease.

Empyemas are usually of infectious origin. Noninfectious causes of empyema may be a considerable diagnostic challenge, as exemplified in the present case report. A 21-year-old male presented with high fever, sore throat and myalgias of 1 week duration. In the following days, bilateral pleural effusions developed, with cellular counts in the pleural fluid up to 117 x 10(9)/liter (98% neutrophils). Despite institution of empiric antibiotic therapy, spiking fever continued. All culture studies resulted in being negative. Following the report of a serum ferritin concentration of 6,975 microg/l, adult-onset Still's disease was diagnosed and successfully treated with anti-inflammatory drugs. This case adds adult-onset Still's disease to the list of noninfectious causes of empyema and underlies the value of measuring serum ferritin as a diagnostic tool.

Evaluation of circulating activin-A as a serum marker of hepatocellular carcinoma.

Because in experimental hepatocarcinogenesis apoptosis increases from normal to preneoplastic to carcinoma tissue, proapoptotic factors, such as activin-A, may represent useful markers for hepatocellular carcinoma (HCC). In this study, serum activin-A was measured in 99 cirrhotic patients, of whom 55 had HCC. Activin-A concentrations were higher in HCC patients (median, 2.33 ng/ml; range, 0.41-8.12) than in patients with nonmalignant cirrhosis (1.28 ng/ml; range, 0.35-6.25) (P < .05). All 12 patients with activin-A greater than 3 ng/ml and serum alpha-fetoprotein greater than 30 ng/ml had HCC, in comparison to 32 of 41 patients who had only one and to 11 of 46 patients who had both markers below these cutoffs (P < .0001). No correlation was found between activin-A and alpha-fetoprotein in the two groups, whereas in patients with HCC, activin-A was strictly correlated with serum aspartate aminotransferase (P < .001). Activin-A mRNA for inhibin betaA subunit was expressed both in tumor and nontumor liver tissues in a case of HCC superimposed on cirrhosis and was not expressed in a case of HCC without cirrhosis. In conclusion, cirrhotic patients with HCC have high serum activin-A, to the production of which both the cirrhotic liver and the liver tumor are likely to contribute.

Kinetics of serum soluble tumour necrosis factor receptor (TNF-R) type-I and type-II after a single interferon-alpha (IFN-alpha) injection in chronic hepatitis C.

Circulating soluble TNF receptors, which act as TNF inhibitors, increase following the administration of IFN-alpha. Whether this is due to a direct IFN action or to indirect mechanisms involving the release of other cytokines is unclear. The kinetics of serum IFN, TNF, IL-6, IL-10, soluble TNF receptor type-I (sTNF-RI) and sTNF-RII were evaluated by enzyme immunoassays in 11 patients with chronic hepatitis C, following the first dose of recombinant human IFN-alpha2b (3 MU given subcutaneously). sTNF-RI concentrations paralleled IFN concentrations, rising from a mean +/- s.e.m. value of 3.5 +/- 0.3 ng/ml at baseline to a peak value of 5.5 +/- 0.5 ng/ml after 9 h, followed by a return to 4.1 +/- 0.4 ng/ml after 24 h (P = 0.0001). sTNF-RII concentrations, which were 7.6 +/- 0.5 ng/ml at baseline, fell initially to 6.9 +/- 0.5 ng/ml, to reach a peak at 24 h of 9.0 +/- 0.7 ng/ml (P < 0.0001). In contrast, the concentrations of TNF, IL-6 and IL-10 fluctuated with no significant changes at any time point. The area under the curve (AUC) of incremental IFN values had a strong positive correlation with the AUC of incremental sTNF-RI values (r = 0.75, P < 0.01). In patients with hepatitis C, IFN concentrations reached after a single dose of IFN were paralleled by correlationally increased concentrations of sTNF-RI, which are a much better marker of administered IFN than sTNF-RII, IL-6 or IL-10.

Relationship among hepatic inflammatory changes, circulating levels of cytokines, and response to IFN-alpha in chronic hepatitis C.

To investigate the relationship among circulating cytokines, inflammation in the liver, and kind of response to interferon-alpha (IFN-alpha) in hepatitis C, we studied 63 consecutive patients (38 male, 25 female), treated with IFN for up to 1 year. Serum tumor necrosis factor-alpha (TNF-alpha) was measured at baseline and after 3 months of treatment. Transient (TR) or sustained response (SR) was observed in 29 and 16 patients, respectively. Baseline levels of TNF < or = 22 ng/L were observed in 69% of patients with SR, 55% of patients with TR, and 22% of nonresponders (p < 0.01). There was a significant correlation between baseline TNF levels and histologic grading score of hepatitis (p < 0.01). After 3 months of treatment, TNF levels >22 ng/L were observed in 63% of patients with SR, 69% of patients with TR, and 83% of nonresponders (p NS). Independent of the treatment outcome, TNF levels were lower at baseline and increased significantly with treatment in patients with lower histologic grading (p < 0.005). In conclusion, in patients with chronic hepatitis C, circulating TNF levels correlate with the degree of inflammation in the liver. Response to IFN is accompanied by an inflammatory response involving the release of TNF.

Antineuronal antibody in a patient with neuroblastoma and opsoclonus-myoclonus-ataxia: a case report.

We describe a case of a patient with neuroblastoma and opsoclonus- myoclonus ataxia displaying serum and CSF anti-Hu antibodies that were able to recognize antigens of the patient's own tumor.

Endogenous interferon-alpha concentration and outcome of interferon treatment in patients with chronic hepatitis C.

To verify its value with regard to the outcome of therapy in chronic hepatitis C, serum interferon-alpha (IFN) was measured by ELISA in 70 patients (43 male, 27 female) with chronic hepatitis C, treated with IFN 9 MU/week subcutaneously for up to one year. Serum IFN was detectable in 49/70 patients, 16 of whom had IFN values >125 pg/ml. Only 1/22 patients who maintained a sustained response six months after the end of treatment had pretreatment serum IFN > 125 pg/ml, in comparison to 15/48 patients who did not respond or who relapsed (chi2 6.1, P < 0.02). At multivariate analysis the predictive value of serum IFN was independent of age, sex, presence of cirrhosis, infection by genotype 1b (improvement chi2 7.1, P < 0.01). In patients with chronic hepatitis C, measurement of serum IFN at baseline might be useful for the selection of patients with higher probability of long-term response.

Increased soluble ICAM-1 concentration and impaired delayed-type hypersensitivity skin tests in patients with chronic liver disease.

AIMS/BACKGROUND: Soluble ICAM-1 may act as an antagonist of the membrane bound form, which is essential for the adhesion of leucocytes to endothelial cells. The aim of this study was to investigate whether the presence of high concentrations of soluble ICAM-1 are related to the impairment of delayed-type hypersensitivity reactions. METHODS: The study population comprised 73 patients (53 men and 20 women) with chronic liver disease (19 with chronic hepatitis, 36 with cirrhosis and 18 with hepatocellular carcinoma), and 21 age-matched controls (11 men and 10 women). Serum soluble ICAM-1 was measured using an enzyme immunoassay. Skin tests for seven different antigens (tetanus, diphtheria, streptococcus group C, tuberculin, Candida, tricophyton, and proteus) were considered positive when diameters > or = 2 mm were recorded; the diameters of positive tests were added to calculate a cumulative score. RESULTS: Patients with chronic liver disease had fewer positive skin tests (median 2) and a lower cumulative score (median 7) than controls (median 3 and 12, respectively). Multivariate analysis suggested the existence of an independent association between alkaline phosphatase and anergy to skin tests and between soluble ICAM-1 concentrations and the cumulative score. CONCLUSIONS: The strong association observed between increased soluble ICAM-1 concentrations and impairment of delayed-type hypersensitivity skin tests suggests that soluble ICAM-1 may be implicated in the immune depression seen in patients with chronic liver disease.

Antineuronal antibodies in patients with neuroblastoma: relationships with clinical features.

We evaluated the frequency of serum antineuronal antibodies in a cohort of 39 neuroblastoma patients and related their presence to clinical features. Twelve patients displayed antineuronal antibodies at immunocytochemistry. Only one of these 12 patients suffered from a clinically overt paraneoplastic syndrome. No significant differences emerged between autoantibody-positive and autoantibody-negative patients in terms of progression-free and overall survival, although when only patients evolving to disease progression were considered, the time interval between diagnosis and progression was slightly longer in autoantibody-positive patients.
