Abstract
From January 1982 to October 1987, 100 patients with multifocal superficial bladder cancer received intravesical MMC at the Institute of Urology, University of Padova. Seventy-three patients had papillary multifocal superficial bladder carcinoma (stages Ta-T1): treatment was divided into therapeutic (18 cases), and prophylactic (55 cases). 27 patients had carcinoma in situ. 39 patients affected by neoplasia relapsed to previous intravesical ADM treatment. All patients received 40 mg. intravesical MMC weekly for 8 consecutive weeks, repeating the cycle in cases of relapse. Complete response rates at 12 months was 53%, 50 to 67% for each group, respectively. Recurrence rate was lower compared to that before treatment; progression rate was also lower compared to a group who received only endoscopic treatment. In patients who relapsed with ADM treatment, the percentage of complete response was 69%. We underscore the efficacy of MMC in lowering relapse and progression in multifocal superficial bladder cancer, which represents the best indication for this kind of treatment.

Abstract
We evaluated nutritional status, pulmonary impairment, nutritional intake, and fat absorption in 73 cystic fibrosis (CF) patients to identify the primary factor(s) influencing growth. In general, the growth pattern in our patients was satisfactory since 60/73 were not underweight. When caloric intake is greater than or equal to 95% of RDA, wasting does not occur regardless of the degree of malabsorption, dietary fat content, or lung involvement. In the group of patients who consume less than the RDA, underweight is related to the severity of pulmonary disease; indeed, 11/13 underweight patients have a chest x-ray score over 15. Steatorrhea is well controlled in most patients; only 11 of 73 show a fat excretion greater than 25% of fat intake. The daily number of capsules of Pancrease varies from 4 to 57. The amount of Pancrease to be given was individualized to meet each patient's requirements using fat balance studies to determine the necessary daily Pancrease dose, then distributing the total dose in proportion to the fat content of each meal.

Abstract
Fifty consecutive patients with Friedreich's ataxia were examined to characterize their cardiac diastolic function. Electrocardiographic abnormalities were detected in 42 (80%) of the 50 patients. Echocardiography showed left ventricular hypertrophy in 14 patients (28%): concentric in 12 and asymmetric in 2. Left ventricular percent fractional shortening was normal in all except 2 patients. Diastolic filling characteristics measured from Doppler mitral flow velocity traces were not statistically different from those of 18 healthy control subjects. No abnormal diastolic flow pattern was observed in patients with left ventricular hypertrophy, whether concentric or asymmetric.

Abstract
Eleven children with cystic fibrosis (CF) and pancreatic insufficiency were given supplementation with taurine (30-40 mg/kg/day) for 2 months, while taking their usual dosage of enzymatic therapy. One patient dropped out of the study because she developed severe constipation. In the other 10 patients, urinary taurine excretion (88 +/- 30.1 mg/m2s.a./24 h) was similar to that of controls (86.2 +/- 6 mg/m2s.a./24 h) before taurine and increased markedly after supplementation (618.2 +/- 79.97 mg/m2s.a./24 h), indicating efficient intestinal absorption. Their coefficient of fat absorption was 81.2 +/- 2.3% and increased significantly after taurine (91.3 +/- 1.13%; p less than 0.01); the area under the curve of plasma triglyceride postprandial levels (1 +/- 0.1 mg X min/ml) also increased significantly after taurine (1.4 +/- 0.3 mg X min/ml; p less than 0.05), showing values very similar to those of controls. Conversely, no change was observed in the serum postprandial levels of glycocholic acid: the maximum postprandial peak before (1.2 +/- 0.3 mumol/l) and after taurine (1 +/- 0.1 mumol/l) remained significantly lower than in controls (2.4 +/- 0.3 mumol/l); p less than 0.01 and p less than 0.001, respectively. Mean total fecal bile acid (BA) excretion was 10.24 +/- 2.15 mg/kg/day before taurine and 12.8 +/- 4.27 mg/kg/day after taurine (normal pediatric values, 2.91 +/- 1.1 mg/kg/day); however, in the individual patients we found a variable trend, four of them showing a net increase in fecal BA excretion.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Steatocrit was determined through microcentrifugation of fecal homogenate from 110 pediatric controls and 107 patients with cystic fibrosis (CF). For 74 CF patients, steatocrit was determined in the same fecal material collected to determine a fat balance. In controls, steatocrit value was 0.7 +/- 1.0%, which was significantly lower than values found in CF patients with a coefficient of fat excretion less than 10% of intake (1.7 +/- 1.2%). Significantly increased values were found in CF patients with a coefficient of fat excretion ranging between 10 and 25% of intake (4.7 +/- 1.7%) and in those whose coefficient of fat excretion was greater than 25% of intake (11.3 +/- 4.3%). In the 74 CF patients, steatocrit was directly correlated to the coefficient of fat excretion (r = 0.93; P less than 0.001). We performed steatocrit several times in the course of the 1st year of life in 33 infants with CF diagnosed by means of CF screening. Values obtained at the time of diagnosis, before starting enzymatic therapy, were relatively high; they showed a progressive decrease when, using steatocrit as a guide, the dose of pancreatic enzymes had been increased. The normalization of steatocrit values was accompanied by a better growth rate in the majority of these infants, confirming the importance of an optimal early correction of pancreatic insufficiency. We propose that this simple semiquantitative test can be usefully performed for the frequent monitoring of fat absorption and for checking the response to enzymatic therapy in patients with CF.

Abstract
To evaluate whether the addition of an aminoglycoside might enhance the clinical efficacy of ceftazidime in cystic fibrosis patients with acute exacerbations of chronic Pseudomonas lung infections we carried out a prospective, comparative, randomized blind study with three schedules: ceftazidime vs. ceftazidime plus sisomicin (C/S) vs. piperacillin plus sisomicin, for a total of 60 courses of 14 days of treatment. Each treatment led to clinical and radiologic improvement with marked reduction of signs of acute infection. Statistically there was no significant difference in clinical responses among the schedules. No side effect appeared during treatments with ceftazidime or C/S. Hyperpyrexia was seen in 35% of patients receiving piperacillin. Decrease in Pseudomonas aeruginosa count to less than 10(5) colony-forming units/ml of sputum was achieved in 60% of patients treated with C/S and in 30% of patients who received ceftazidime or piperacillin plus sisomicin (statistically not significant). A transient increase in mean geometric minimal inhibitory concentrations for ceftazidime and piperacillin was observed at the end of the combined therapies. A larger percentage of persistent resistant strains of P. aeruginosa was seen after the combined therapies. We conclude that ceftazidime as monotherapy may be an effective alternative in Pseudomonas lung infections in cystic fibrosis patients. Its clinical efficacy seems not to be enhanced by the addition of an aminoglycoside, although reduction of Pseudomonas in the sputum was better achieved by the combination of C/S.

Abstract
The effect of saline extracellular volume expansion (4 ml/min/10 kg b.w. X 60 min) on renal function has been studied in patients with cystic fibrosis (CF) and in normal age-matched controls. Basal values for glomerular filtration rate (GFR), renal plasma flow (RPF), tubular sodium and chloride (Na, Cl) handling were similar in both groups. Saline expansion resulted in an increase in GFR and RPF in the CF patients: 127 +/- 18 ml/min/1.73 sqm BSA to 166 +/- 5; p less than 0.001, but not in the control group: 112 +/- 10 to 120 +/- 20. These hemodynamic changes were associated with increased proximal tubular reabsorption of NaCl in the CF patients whereas controls had reduced NaCl reabsorption. Renin and aldosterone levels suggested that increased NaCl reabsorption in CF patients was not secondary to chronic extracellular volume contraction or salt loss. These results support the hypothesis that the renal tubule is involved in the generalised electrolyte transport disorder exhibited in other epithelial structures. This study also indicated that the regulation of renal hemodynamics is altered in CF. The relationship between the disorder of proximal tubular salt handling and changes in renal hemodynamics is not known, but the observed changes imply a tubulo-glomerular feedback mechanism.

Abstract
Dermatitis herpetiformis was diagnosed in seventy-six children by its clinical features and by detection of granular IgA deposits in the papillary dermis of perilesional skin. Enteric alterations demonstrated by measurement of D-xylose absorption and by small intestinal biopsies were detected in over 90% of all patients. A complete follow-up was obtained for all children who were followed for 3 to 10 years. Treatment with a gluten-free diet alone led to a reversal of the intestinal abnormality in 100% of our children and to the disappearance of cutaneous lesions in 82% of reported cases. This suggests that a complete remission of symptoms can be obtained with a gluten-free diet alone. Dapsone alone is effective therapy for the rash but does not affect the intestinal alterations. Furthermore, the lack of side effects to dietetic therapy for a long period of time makes the diet the treatment of choice in this disease.

Abstract
Serum conjugated cholic acid (CCA) and conjugated chenodeoxycholic acid (CCDCA) fasting levels were measured in 30 children with cystic fibrosis (CF) without liver involvement, and mean levels were not significantly different from control values. In seven children (four with partially corrected pancreatic insufficiency and three without pancreatic insufficiency) serum levels of both primary bile acids (BAs) were also measured after the ingestion of a standard liquid meal; the values were then compared with those for total and fractional fecal BA excretion. The CCA mean peak increase was significantly reduced in patients with pancreatic insufficiency (p less than 0.01), as well as in those without pancreatic insufficiency (p less than 0.05), as compared to controls. The CCDCA mean peak increase was reduced only in patients with pancreatic insufficiency (p less than 0.01). Fecal results confirmed serum data, showing a significantly increased excretion of cholic and deoxycholic acids in patients without pancreatic insufficiency as compared to controls (p less than 0.02), despite a similar total BA excretion. In patients with pancreatic insufficiency, total fecal BA levels were markedly increased compared to control values (p less than 0.001); the fecal percentage of chenodeoxycholic and lithocholic acids was greater than that recorded in patients without pancreatic insufficiency (p less than 0.05), in agreement with the different behaviour of serum CCDCA postprandial curves for the two groups of patients. The results are consistent with selective malabsorption of cholic acid in CF, independent of the presence of pancreatic insufficiency; they confirm the usefulness of serum BA postprandial determinations in measuring BA malabsorption.

Abstract
HLA phenotypes of 64 Italian pediatric patients with celiac disease (CD) were compared with those of a group of healthy controls. DR3 and DR7 are significantly increased as reported in other populations. In addition an increase of heterozygotes DR5/DR7 was observed in our patients. The Hardy-Weinberg distribution in the patients group shows a disequilibrium due to the genotype DR5/DR7. Our data confirm that more than one HLA gene product is associated with CD: one with DR3 and the other with DR7.

Abstract
It has been suggested that the adynamic or hypokinetic appearance of the ventricular septum is a unique echocardiographic feature of hypertrophic cardiomyopathy (HC). To determine how characteristic of HC the adynamic septum is, 70 patients with this disease, and 31 with other cardiac diseases that produce left ventricular (LV) hypertrophy and pressure overload (aortic valvular stenosis or systemic hypertension), and 25 subjects with normal hearts were studied by echocardiography. On M-mode echocardiography, 53 of 70 patients (75%) with HC had an abnormally low value for percent systolic thickening of the septum associated with either reduced or normal septal excursion; however, 17 patients (25%) showed normal septal dynamics. Twenty of 31 patients (64%) with other cardiac diseases that produce pressure overload showed normal septal thickening and excursion, while 11 (36%) had reduced systolic thickening associated with either diminished or normal excursion. Greatly reduced values for percent systolic thickening of the septum were present both in patients with HC (13 +/- 1%) and in patients with other cardiac diseases (21 +/- 2%). However, differences in systolic septal thickening between the 2 groups were largely a manifestation of the greater absolute diastolic septal thickness in patients with HC. When values for percent systolic thickening were normalized for diastolic septal thickness, or when systolic thickening was compared in only patients with similar diastolic septal thicknesses, differences in septal thickening between patients with HC and those patients with other cardiac diseases were not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A stimulated altitude of 7000 m was applied in rats chronically exposed to hypoxia in a hypobaric chamber. In these experimental conditions the contralateral ventricle not exposed to pressure overload (that is, the left) showed a significant degree of hypertrophy. The hypoxic stimulus did not affect systemic artery pressure or the heart rate. Chronic adrenergic stimulation performed in the rat treated with low doses of isoprenaline (a direct stimulating adrenergic drug) or with tyramine (primarily a releaser of endogenous catecholamines) induced hypertrophy of the right ventricle, left ventricle, and interventricular septum without modifying the haemodynamic parameters mentioned above. The development of ventricular hypertrophy in the absence of pressure overload is stressed. A role for neurohumoral factors (that is, adrenergic stimulation and catecholamines) in the development of ventricular hypertrophy is suggested.

Abstract
A retrospective approach has been adopted to investigate the frequency and duration of breast feeding and the time of gluten introduction in the diet in 216 celiac children and their healthy siblings of three different centers--Naples, Milan, and Turin. In this matched case-control study, the selected controls were healthy siblings of the cases. Children formula-fed from birth, or breast-fed for less than 30 days, were found to have a relative risk of developing symptoms of celiac disease four times higher than children breast-fed for more than 30 days (p less than 0.0001). To investigate more deeply the effect of the duration of breast feeding as a possible protecting factor, the linear trend for different periods of breast feeding was tested and found to be highly significant (G1: 18.3 with 1 df). Therefore, increased duration of breast feeding is associated with decreased risk of developing celiac symptoms. On the contrary, there was no apparent relationship between early introduction of gluten into the diet and frequency of celiac disease. Our findings are consistent with the hypothesis that a wider diffusion of breast feeding is a factor underlying the recently reported decrease of the incidence of celiac disease in children.

Abstract
The pharmacokinetics and clinical efficacy of ceftazidime, a cephalosporin with activity against Pseudomonas aeruginosa, were studied in children with cystic fibrosis. Ceftazidime had high in vitro activity against P. aeruginosa strains isolated from our patients, with a mean MIC90 of 8 micrograms/ml. The first dose of 50 mg/kg IV of ceftazidime achieved serum concentrations of 40.8 +/- 19.7 micrograms/ml at one hour and 3.8 +/- 1 micrograms/ml at four hours after administration (mean values +/- SD). The MIC90 was exceeded by serum concentrations for up to three hours. The elimination of the drug from the blood followed a biexponential decay with an elimination half-life of 60.4 +/- 6.8 min and a total body clearance of 6.0 +/- 3.1 ml/min/kg. Renal clearance of the drug accounted for 75% of the total clearance; these are higher values than those reported for adults. Peak concentrations of ceftazidime in the sputum two hours after a single administration were 4.13 +/- 2.06 micrograms/ml; after seven and 14 days of treatment, sputum concentrations were significantly lower. Eleven children with acute pulmonary exacerbation were treated for 14 days with ceftazidime at a dose of 150 mg/kg/day (12 treatment courses). Significant clinical and radiologic improvements were obtained in nine of 12 patients. In six of 11 cases the P. aeruginosa count decreased by 10(4) CFU/ml. Ceftazidime was well tolerated, and no side effects appeared during treatment.

We correlated the incidence and degree of exercise induced ventricular arrhythmias (EIVA) with the angiographic severity of coronary artery disease (CAD) in 162 patients with a history of stable effort angina, all showing a positive exercise stress test for myocardial ischemia and a greater than or equal to 70% stenosis of a major coronary artery. Patients were grouped according to the following criteria: presence of electrocardiographic evidence of old transmural myocardial infarction (MI), number of significant coronary stenoses and number of left ventricular (LV) areas showing abnormal segmental wall motion (ASWM). The incidence of EIVA in patients with multivessel CAD was higher than in patients with single vessel CAD, but this difference was not statistically significant. The number of LV areas with ASWM was better correlated with the frequency of EIVA, which was 20.0% in patients with normal LV wall motion, 31.2% in patients with 1 area of ASWM, 54.0% in patients with 2 areas of ASWM (p less than 0.005 vs normal LV wall motion), 74.1% in patients with 3 or more areas of ASWM (p less than 0.001 vs normal LV wall motion and 1 area of ASWM), and 81.8% in patients with LV aneurysm (p less than 0.001 vs normal LV wall motion and 1 area of ASWM, p less than 0.005 vs 2 areas of ASWM). Patients with old MI showed a significantly higher incidence of EIVA than those without MI (p less than 0.001), but this difference was due to the more severe LV asynergy in the MI group. In conclusion, our results show that, in a selected population of patients with CAD, the incidence of EIVA correlates better with the extent of LV segmental wall motion abnormalities than with the number of diseased coronary arteries or the presence of an old transmural MI.

Abstract
A 36-year-old woman was admitted to our hospital with exertional dyspnea, palpitation and cardiac enlargement on standard chest X-ray. Physical examination did not reveal any significant abnormality and routine laboratory tests were normal. ECG showed atrial fibrillation and negative T waves in lead III and a VF, with a stiffened ST segment. M-mode echocardiography showed absence of pericardial effusion and normal size of both ventricular chambers. Two-dimensional echocardiography showed a large saccular dilation of the right atrium without significant enlargement of other cardiac chambers. A slight displacement of tricuspid valve leaflets was also present. Cardiac catheterization was effective in the diagnosis of idiopathic enlargement of the right atrium. Although two-dimensional echocardiography has some limitations in the diagnosis of this unusual malformation, it may prove useful in the noninvasive follow-up of these patients, in order to monitor the eventual increase of atrial size and to promptly detect late complications.
