Hemodynamic effects of creatine phosphate in patients with congestive heart failure: a double-blind comparison trial versus placebo.

BACKGROUND: The use of metabolic drugs effective in addition to conventional therapy represents a significant challenge in patients with left ventricular dysfunction. HYPOTHESIS: The aim of this double-blind, placebo-controlled study was to investigate the hemodynamic effects of acute intravenous (i.v.) administration of creatine phosphate (CP) and of short-term treatment in patients with congestive heart failure (CHF) from ischemic heart disease (IHD) or dilated cardiomyopathy in addition to conventional therapy. METHODS: We compared the hemodynamic effects of exogenous creatine phosphate (CP) and placebo in a double-blind, crossover design study in 13 hospitalized patients (12 men, 1 woman, mean age 52 +/- 8 years) with CHF. All patients were in New York Heart Association (NYHA) class II-III and received conventional pharmacologic therapy for CHF; this was not changed during the study period. The study design consisted of two treatment periods (CP or placebo and placebo or CP, respectively) of 4 days each, separated by a 2-day washout interval. The intravenous infusion consisted of 6 g CP or placebo (acute treatment) or 6 g CP or placebo daily for 4 days (short-term treatment) diluted in 50 ml of NaCl 0.9%; infusion duration was about 10 min. Mono-bidimensional echocardiographic examination (Hewlett Packard Sonos 1000, with a 2.5 MHz transducer) was performed at baseline, after acute infusion, and 12 h after the end of short-term treatment. Data were analyzed by ANOVA and Student's t-test for paired data; the results obtained after acute and short-term therapy were compared with the baseline values. RESULTS: After placebo therapy, no significant change was observed. The results after treatment with CP showed a significant reduction of end-systolic diameter [baseline: 4.5 +/- 0.6; acute: 4.2 +/- 0.5, (p < 0.001); short-term 4.3 +/- 0.6 cm, (p < 0.05)] and systemic vascular resistance (baseline: 1064.9 +/- 483.7; acute: 947.5 +/- 390.2 (p < 0.05); short-term: 950.7 +/- 394.3 dyne-s-cm-5 (p < 0.05); moreover, a significant increase of percent ejection fraction [baseline: 48 +/- 12%; acute 53 +/- 12% (p < 0.01); short-term 52 +/- 11% (p < 0.01)], and of percent fractional shortening [baseline: 25 +/- 7; acute 28 +/- 8 (p < 0.05); short-term 28 +/- 7% (p < 0.05)] was observed. CONCLUSION: CP was shown to improve cardiac function, even in the presence of a conventional CHF pharmacologic therapy.

Reactive arthritis by staphylococcus epidermidis: report of an unusual case.

In the literature many cases of Staphylococcus epidermidis (SE) complications are reported, but we have not found any reference about reactive arthritis secondary to SE. We report an unusual case of a patient with SE bacteriaemia, who developed elbow arthritis, asymmetrical sacroiliitis, keratoderma and restrictive cardiomyopathy. The clinical pictures, the instrumental and biochemical findings, in particular the positivity of HLA B27, allow us to set this case in the complex and heterogeneous chapter of reactive arthritis.

Incidence of non-A, non-B and HCV positive hepatitis in healthcare workers in Italy.

In Italy, using figures from a surveillance system for acute viral hepatitis, the incidence rate of acute non-A, non-B hepatitis (NANBH) and hepatitis C virus (HCV) hepatitis cases was evaluated in healthcare workers (HCWs) and the general population of the same age over the period 1988-1994. The NANBH incidence among the general population declined from 4.7/100,000 in 1988 to 2.1/100,000 in 1994; the corresponding figures among HCWs were 12.3/100,000 (RR 2.62; CI 95% = 1.66-4.15) in 1988 and 4.3/100,000 (RR 2.05; CI 95% = 1.13-3.77) in 1994. Since 1991, NANBH cases have been tested for antibodies to HCV (anti-HCV). During the period 1991-1994 the proportion of NANBH cases tested for anti-HCV was 81% (38/47) in HCWs and 85% (1019/1193) in other NANBH cases. A similar proportion of NANBH cases in each group (74% and 70%) were shown to be due to HCV. The incidence rate of HCV positive cases among the general population was 1.3/100,000 in 1991 and 1.8/100,000 in 1994; the corresponding figures among HCWs were 3.7/100,000 (RR 2.85; CI 95% = 1.42-5.92) in 1991 and 3.1/100,000 (RR 1.72; CI 95% = 0.88-3.59) in 1994. The proportion of cases with jaundice was 56.2% in HCWs and 63.7% in the general population. Needlestick injury without major risk factors such as blood transfusion, intravenous drug use or surgical intervention was reported by 12.0% of HCWs and by 0.1% of the general population. Lack of any risk factor was reported by 40.2% of HCWs. These findings strongly suggest that in Italy healthcare workers are at greater risk than the general population of acquiring NANBH, as well as HCV.

Risk factors for recent toxoplasma infection in pregnant women in Naples.

Effective primary prevention of congenital toxoplasmosis requires up to date information on locally relevant risk factors for infection in pregnant women. In Naples, risk factors for toxoplasma infection were compared in recently infected women (as assessed by detection of specific IgM in serum) and susceptible, IgG negative women. Recent infection was strongly associated with frequency of consumption of cured pork and raw meat. Eating cured pork or raw meat at least once a month increased the risk of toxoplasma infection threefold. This simple study design for determining locally relevant sources of toxoplasma infection is the first report of cured pork as a risk factor for infection. Further research is required to determine cyst viability in cured pork products. Our findings suggest that in southern Italy, cured pork and raw meat should be avoided by susceptible pregnant women.

[Heart involvement in Behcet's disease: a personal caseload en review of the literature].

BACKGROUNDS: Various cardiac abnormalities have been described in patients with Behçet's disease. The number of reports remains small, but increasing awareness have widened the spectrum of manifestations. We report our evaluation of cardiac involvement in 15 patients affected by Behçet's disease, diagnosed according to the criteria for the International Study Group for Behçet's Disease. PATIENTS AND METHODS: All the patients have been examined by a clinical, biochemical and instrumental point of view. Six patients resulted to be affected by heart diseases, in particular by mitral valve prolapse; moreover one of them presented an unexpected dilatative cardiomyopathy. CONCLUSIONS: The authors affirm that the pathological heart features are not so uncommon as previously reported in literature, emphasizing the necessity of a constant evaluation for the cardiovascular system also in the asymptomatic patients.

[The efficacy and safety of glucosamine sulfate in the treatment of gonarthritis].

This study was performed to evaluate the therapeutic efficacy and tolerability of glucosamine sulfate in patients with gonarthritis. During the 12-month study period, the signs and symptoms of the disease were evaluated, as well as the dosage of the urinary pyridinoline. In this trial, we demonstrated that glucosamine sulfate has a chondroprotective activity, which was significant after the first 3 months of therapy. Moreover, this study showed that the side effects due to glucosamine sulfate were mild to moderate and did not require discontinuation of the drug.

[Hyperechogenicity of the renal medulla in children: clinico-echographic correlations].

Increased renal medullary echogenicity by renal ultrasound associated with hypercalciuria and nephrocalcinosis is often present in childhood. 17 children, 9 boys and 8 girls, aged from 8 months to 10 years were classified into three groups based on ultrasound findings according to Patriquin and Robitaille: type A faint hyperechogenic rim around the sides and tip of the medullary pyramid; type B more intense echogenic rim of the pyramids; type C intense echoes throughout the pyramid. Clinic-echographic correlations showed a pattern C in 4 children with distal renal tubular acidosis and in an infant treated with furosemide; pattern B in 3 patients having different types of tubulopathy associated with hypercalciuria; pattern A in 6 children with congenital tubulopathy and in 3 children treated with vitamin D. Abdominal X-rays detected medullary calcinosis in 2 (11.7%) of total 17 patients. Ultrasonography appears to be an important tool in early diagnosis of renal medullary nephrocalcinosis.

[Echographic diagnosis of nephro-urological neoplasia in a pediatric nephrology center].

The use of ultrasound for the diagnosis of urologic neoplasms in simple and accurate. Nowadays nephrologists and urologists advocate the use of ultrasound and the procedure now plays a complementary role of the clinical examination. We present a retrospective study regarding our experience with ultrasonography in the diagnosis of urologic problems. In the period february 95-february 96 we performed 672 ultrasound examination on children ranging in age from 30 days to 16 years. All examinations were performed using a 3.5-5 MHz real time convex scanner. The patients were examined in the supine position for imaging of the bladder and in the prone position for imaging of the kidneys. We report 3 cases of neoplasm of the genito-urinary tract screened with the use of ultrasounds in a selected paediatric population.

Tolerability of nabumetone: a pilot in vitro study showing absence of injury to articular cartilage.

Nabumetone, a compound of the naphthylalkanone class, has shown considerable anti-inflammatory, analgesic and antipyretic effects, together with high systemic and organ-specific tolerability. Its reputation for tolerability has been increased by an in-vitro study evaluating the mature collagen metabolism's markers under nabumetone treatment, which shows that, nabumetone does not interfere with collagen synthesis. Therefore, unlike some nonsteroidal anti-inflammatory drugs, nabumetone might not be injurious to articular cartilage. This feature makes nabumetone even safer for long-term treatment of rheumatic and orthopaedic conditions.

Beauty treatments and risk of parenterally transmitted hepatitis: results from the hepatitis surveillance system in Italy.

The role of ear-piercing, tattooing, attendance at chiropodist or manicurist and barber shop shaving in transmitting hepatitis B and hepatitis non-A, non-B was evaluated. Data reported here were collected from 1985 to 1993 by the National Viral Hepatitis Surveillance System. The association between parenterally transmitted hepatitis and the considered risk factors was estimated, comparing 6,395 hepatitis B and 2,558 hepatitis non-A, non-B cases with 4,789 hepatitis A cases, using the case-control method. Of the non-A, non-B cases tested from 1991 to 1993, 56.6% were anti-HCV positive. The incidence of parenterally transmitted hepatitis cases reporting specific beauty treatments was also evaluated. Tattooing, ear-piercing and barber shop shaving were associated with both parenterally transmitted hepatitides, while attendance at a chiropodist or manicurist was associated only with hepatitis B. During the study period the incidence of acute hepatitis B and non-A, non-B cases reporting beauty treatments declined by 49%. In spite of this decline, considering that a large part of the general population is exposed to the considered risk factors, the role of beauty treatments in transmitting hepatitis B and hepatitis non-A, non-B should not be underestimated.

Case control study of risk factors for hepatitis A: Naples 1990-1991. Hepatitis Collaborating Group.

An increased incidence of hepatitis A was observed in Naples from 1990-1991. A hospital-based case-control study was carried out to evaluate the relative importance of various risk factors. A hundred and ninety-eight cases and 238 hospital controls were recruited during the study period. The strongest association was contact with a jaundiced person among children. A correlation was also shown for children and adults with raw shellfish consumption and pre-school nursery attendance or presence in the household of children attending pre-school nurseries. History of travel and intravenous drug use were risk factors for adult subjects. Considering the relative importance of the specific risk factors we found that 38% of the acute hepatitis A cases were attributable to contact with a jaundiced person, 15% to presence in the household of children attending pre-school nurseries and 28% to raw shellfish consumption.
