Abstract
BACKGROUND The present study has been carried out in order to assess the clinical and functional efficacy and tolerability of galactosa-minoglucuronoglycan sulphate (GGGS). The molecule has been intra-articularly administered in patients affected by moderate primary gonarthritis, according to clinical and functional parameters. METHODS At the beginning and at the end of each period of treatment the following parameters have been evaluated: spontaneous pain, provoked pain, pain during active movement, pain during passive movement, pain at rising (7-8:00 a.m.) pain at bed time (10:00 p.m.), execution time (expressed in seconds) of up-down from a chair (five times), execution time (expressed in seconds) to walk 15 meters. Fifty patients affected by osteoarthritis of the knee were treated weekly, during one year, for two periods of six weeks each with a total amount of 12 injections. RESULTS Treatment with Galactosaminglucuronoglycan sulphate (GGGS) seems to be effective in the therapy of osteoarthritis of the knee. The pain scores decreased and the functional levels significantly (p < 0.01) improved in a large proportion of patients and GGGS was very well tolerated. CONCLUSIONS This study suggests that intra-articular treatment is a substantially new way for GGGS administration in the therapy of osteoarthritis of the knee.

Abstract
BACKGROUND We evaluated the clinical efficacy and the tolerance of Nabumetone (N), in comparison with a pool of non-steroidal anti-inflammatory drugs (NSAIDs), in a cohort of patients affected by rheumatoid arthritis, osteoarthritis, non-articular rheumatisms and primary fibromyalgic syndrome. METHODS One hundred and seventy patients were observed in an open-non randomized study. The patients have been recruited alternatively and subdivided into two groups: 84 patients that received N and 86 patients that received one of the other NSAIDs. All the patients affected by rheumatoid arthritis received a disease-modifying anti-rheumatic drug (OH-chloroquine, d-penicillamine, auranofin, cyclosporine-A); while benzodiazepines are administered in the patients suffering from primary fibromyalgic syndrome. A follow-up not inferior to 12 consecutive weeks was realized and the following clinical parameters were studied: spontaneous pain, provoked pain, pain on active movement, pain on passive movement, pain at rising, pain at bed time, morning stiffness, limited joint mobility, number of tender points, number of affected joints and number of swollen joints. All the patients were monitored for hematological, biochemical, urinary and clotting tests. RESULTS The results revealed an excellent tolerability of nabumetone with a clinical efficacy not inferior to the NSAIDs' pool. Moreover, the number of drop-outs in the N-group were significantly inferior in comparison to the NSAIDs'-pool group. CONCLUSIONS We conclude that N can be considered as effective as other NSAIDs. Moreover it seems to be better tolerated that the other NSAIDs utilized in our study.

Abstract
The clinical efficacy and the tolerance of galactosaminoglucuronoglycan sulphate (GGGS), administered both orally and intra-articularly were evaluated for the treatment of generalized and localized osteoarthritis (OA). The study included 154 patients: 52 treated orally with GGGS, observed during three periods of three consecutive months of therapy followed by eight weeks of withdrawal, 52 treated only with non-steroidal anti-inflammatory drugs (NSAIDs), and 50 patients treated two times in a year with a total of twelve (6 x 2) knee intra-articular weekly injections. The tolerance to GGGS was excellent, and the monitoring of the clinical measurements revealed a significant improvement of the articular data with a decreasing of NSAID's consumption.

Abstract
OBJECTIVE Diabetic patients (DP) refer increased hunger sensation (HS) when hyperglycemic but not yet ketogenic. As HS shows a within-day (ultradian cyclicity) and intra-day (circadian cyclicity) repetitivity, its recursive pattern was investigated in patients with type 1 and type 2 diabetes mellitus (DM), in compensated and uncompensated metabolic stage. METHOD HS was approached in its cyclic structure by means of spectral analysis (SA), and in its circadian rhythmicity by means of Single Cosinor analysis (SCA), applied to self-rated scores of HS given every 30 min to their HS (orexigram) by DP. RESULTS Exaggerated periprandial, interprandial, and/or nocturnal peaks of HS were seen in the orexigram of both the type I and type II DP. Specific alterations in HS periodogram were detected, structurally denoting a relative prevalence of the ultradian components along with the deamplification and loss of the circadian harmonics. DISCUSSION The increase of HS (hyperorexia) in nonketotic DM may be formally attributed to a mechanism of frequency multiplication and amplitude demodulation in the multifrequency bioperiodic structure which physiologically regulates the recursive pattern to the daily HS in human beings.

Abstract
A study was performed to assess the efficacy and tolerability of rifaximin in the treatment of encephalopathy during cirrhosis of the liver. Fifty-five patients suffering from grade 1, 2 and 3 portosystemic encephalopathy, with a mean age of 58.9 years (range 30 to 86 years) were evaluated. The patients were treated for 15 consecutive days with rifaximin, an antibiotic which is not absorbed by the intestinal wall, at a dosage of 1200 mg/day in association with sufficient lactulose to induce 2 or 3 evacuations per day. Combined use of the 2 drugs proved an efficient means of controlling the majority of signs and symptoms. After just a few days, an improvement in the signs of encephalopathy was noted in all patients. The treatment was well tolerated and the patients completed the trial without any drug-related side-effects. The results of our trial, although in the context of an open assessment, confirm the clinical efficacy of rifaximin in association with a non-absorbable disaccharide such as lactulose. The 2 compounds have a synergetic effect in reducing ammonia-producing flora. Its efficacy and good tolerability make rifaximin a valid alternative to the use of aminoglycoside antibiotics associated with disaccharides in the treatment of patients with liver disease, particularly in the case of prolonged therapy.

Abstract
The Authors report the results of a study intended to asses the prevalence of obesity in Terni's medical department. Body mass index (BMI) was used as a measure of obesity: it can easily be calculated from weight and height (W/H2) for any individual. A sample of 1195 patients (569 males and 626 females) was studied; obesity was found in 30% of the females and in 10% of the males.

Abstract
The presence of HBV DNA was assessed in the serum samples from 878 HBsAg negative Sardinian blood donors. They were composed of 481 (55%) donors selected because of abnormal serum alanine aminotransferase (ALT) levels during routine testing of their blood donation, and of 397 donors (45%) selected on the basis of normal serum ALT activities. HBV DNA sequences were detected in 37 (7.7%) out of 481 subjects with abnormal ALT and in 2 (0.5%) out of 397 subjects with normal ALT. Anti-HBc was detected in 199 (41%) of the 481 subjects with abnormal ALT and in 81 (20%) out of 397 subjects with normal ALT. Among the 39 subjects positive for serum HBV DNA, 12 (31%) were positive for anti-HBc, while 27 (69%) were negative for all serological HBV markers. These data show in Sardinia, where HBV infection is endemic, there is a high frequency of HBsAg negative HBV DNA positive individuals in whom multiplication of HBV may occur without conventional serological HBV markers, suggesting the possible existence of HBV-like viruses which may be responsible for some of the presumed non-A non-B hepatitis.

Abstract
Fifteen Hodgkin's disease patients (8 male, 7 female) aged 19-72 years, who had been in complete unmaintained remission for 1 year or more when the study was initiated, were given 50 mg thymostimulin (TS) IM daily for 60 consecutive days. When compared with 26-30 age- and sex-matched controls, as a group the patients' circulating ENR+, OKT+3, and OKT+4 cells were depressed (0.001 less than or equal to P less than or equal to 0.06), whereas their OKT+8 cell population was not. Low (greater than 1 SD or greater than 2 SD below mean in controls) or borderline (mean value of two subsequent tests greater than 1 SD below mean in controls) values of ENR+, OKT+3, and OKT+4 cells were seen in nine (group I) of the 15 patients tested, while the remaining six patients (group II) had normal T-cell proportions. Following TS treatment, the proportions of ENR+, OKT+3, and OKT+4 cells increased to normal in all group I patients. The T-cell levels, however, decreased to pretreatment values 60-70 days after completion of TS therapy. TS had no effect on the group II patients whose T-cell percentages had initially been normal. Spontaneous cell-mediated cytotoxicity (SCMC) was assessed in 11 patients, and irrespective of the baseline values, there was a significant enhancement (P less than 0.005) by day 15 of TS administration, which was maintained during treatment. SCMC, however, returned to pretreatment levels 60-70 days after TS was discontinued. The delayed skin test reactivity to DNCB was significantly depressed in all cases. Although TS restored the T-cell proportions, it failed to reverse DNCB reactivity from negative to positive in any of the patients tested. TS can thus restore defective T-cell frequencies and can enhance cytolytic functions that are potentially important in host immunosurveillance, but it apparently failed to improve the skin reactivity to neoantigen.

Abstract
There are no definitive data on the frequency of beta-thalassaemia in the Province of Terni; a mass screening programme has not been carried out. Preliminary studies confirm that there is a strong incidence of beta-thalassaemia heterozygotes. A theory can be put forward for the presence of beta-thalassaemia trait, based on the notion of the multicentric genesis of the disorder: the malaria may have been the dominant selective factor.

Abstract
We determined erythrocyte concentration of phosphorylated glycolytic intermediates and adenosine nucleotides in 9 non-ketotic diabetics under different conditions of glycemic control. We showed a significant increase of G6P, F6P and FDP levels in the 9 diabetics with poor glycemic control, whereas other phosphorylated glycolytic intermediates were in the normal range. After achieving fair glycemic control G6P, F6P and FDP fell to normal value. G6P, F6P and FDP were well correlated with simultaneously determined plasma glucose. Another 5 diabetics with poor glycemic control were connected to Biostator in order to determine the time relationship between blood glucose and erythrocyte levels of G6P, F6P and FDP. We demonstrated a prompt decrease to the normal values of the phosphorylated glycolytic intermediates where blood glucose fell to normal 60-90 minutes after automatic insulin delivery. Finally, we determined RBC glycolytic intermediates in 5 subjects with normal OGTT and in 5 subjects with normal fasting plasma glucose but abnormal OGTT. In this group we observed a prompt and persistent increase of G6P, F6P and FDP levels over the three hours hyperglycemia phase which has been induced by glucose load. No significant increase was found in subjects with normal OGTT. Our results demonstrate that erythrocyte glycolytic metabolism in abnormal in diabetics, depending strictly on the degree of glycemic control.

Abstract
The authors report a case of pheochromocytoma revealed by a de novo appeared hypertension in a young female patient at her 3rd trimester of pregnancy. An early diagnosis and an appropriate medical management allowed a successful maternal outcome. Since maternal and fetal prognosis of pheochromocytoma associated with pregnancy is strictly related to an antepartum diagnosis, the importance of suspecting pheochromocytoma as underlying cause of de novo appearing hypertension (or hypertension of unknown origin) during pregnancy is emphasized. Biochemical tests (plasma and/or urinary catecholamine or metabolite determination) are recommended as the most suitable approach to the screening of pheochromocytoma in pregnancy.

Abstract
In order to verify whether or not insulin-induced blood glucose control can acutely lower glycosylated haemoglobin levels, HbAI (a+b+c) (HbAI) was measured in 11 diabetics before, during and after 3 days of treatment with an "artificial endocrine pancreas" (Biostator). Initially 5 patients were in fair glycaemic control (group A), while the other 6 showed poor control (group B). HbAI levels decreased significantly after 3 days in both groups A (from 9.6 +/- 0.2% to 8.5 +/- 0.3%, mean +/- SEM, p less than 0.05) and B (from 13.7 +/- 0.2% to 12.6 +/- 0.3%, p less than 0.05). A further HbAI decrease was observed until day 60 following Biostator treatment, during which period glycaemic control improved, as assessed by fasting and post-lunch plasma glucose values and daily glycosuria determined every 10 days. These results suggest that increased HbAI levels may be reversed early by strict blood glucose control during a 3 day period. It is concluded that HbAI levels not only reflect long-term glycaemic control, but also recent acute variations in mean blood glucose values.

RBC 2,3-DPG resulted statistically increased versus normal subjects in 22 insulin-dependent diabetics affected by arterial vasculopathy and in 19 vasculopathic non-diabetic patients. RBC 2,3-DPG, on the other hand, did not differ from the normal mean in 16 insulin-dependent diabetics without vascular involvement. The increase of RBC 2,3-DPG represents principally a consequence of the vasculopathy.

Abstract
Sympathetic activity was determined in 13 ketoacidotic diabetics by evaluation of plasma and urinary catecholamines, before and in the course of medical management. Patients were divided into two groups. Group A (severe ketoacidosis, n = 5) and Group B (moderate ketoacidosis, = 8), depending on plasma glucose, pH and plasma bicarbonate levels. The results showed an enhanced sympathetic activity in all patients before treatment, with significant decrease during therapy. In Group A plasma catecholamines were higher than in Group B, both before and in the course of therapy. A significant correlation was found between basal plasma catecholamines and initial plasma glucose, plasma bicarbonate, hours of therapy and insulin dosage required to obtain plasma glucose levels below 150 mg/100 ml .These results, suggesting a close correlation between glycometabolic control and adrenergic activity, emphasize the role of the sympathetic nervous system as a powerful contrainsular factor in the pathogenesis and metabolic derangement of diabetic ketoacidosis.
