Abstract
In order to characterize biochemical markers of bone turnover in home parenteral nutrition(HPN) patients, 8 adult patients on HPN for benign intestinal failure were studied at 0, 6 and 12 months by evaluating serum osteocalcin (bone formation marker), urinary hydroxylysyl pyridinoline, lysyl pyridinoline and beta-galactosyl hydroxylysine (bone resorption markers), serum PTH, Calcitonin, 25 vitD, 1-25vitD, serum and urinary minerals, body weight, rehabilitation degree and HPN characteristics. Three patients entered the study 2-3 months after the beginning of HPN. Their features of bone turnover were homogeneous, characterized by increased resorption associated with normal or increased formation, at baseline, and normalization of resorption associated with an increase or a parallel decrease of formation, at 6 months. At 12 months, the patterns were similar to those observed at 6 months. The patients were not of the same sex and age and had different underlying diseases and types of intestinal failure, HPN composition and serum vitamin D levels. They had weight gain that was already present at baseline and the positive outcomes of the rehabilitation and clinical status in common. Five patients entered the study more than 1 year after the beginning of HPN. They showed heterogeneous features of bone turnover that were stable throughout the study, characterized by increased resorption associated with low or normal formation in two cases, low normal resorption associated with low or normal formation in three. In one patient, who had increased resorption and low formation, the bone turnover appeared to be explained by the nutritional and clinical outcomes, which were negative. These results appeared consistent with those obtained in previous studies by bone histomorphometry, indicating that bone turnover of short-term HPN patients differed from that of long-term patients, and suggesting that the early months of HPN were associated with increased bone resorption.

Abstract
The morphologic and cytoproliferative patterns of the duodenal mucosa of two adult patients, one of whom had a short bowel, were evaluated after more than 2 months of postoperative total parenteral nutrition and 2 and 12 months after the resumption of oral alimentation. Morphometric analysis was performed on routinely processed duodenal biopsies. Cell proliferation was evaluated by means of in vitro bromodeoxyuridine uptake. The results were compared with those obtained in five healthy controls. After parenteral nutrition, patients showed significantly lower villus height and crypt depth than those of controls and a normal bromodeoxyuridine labeling index. After 2 months of refeeding, villus and crypt returned to normal, and the labeling index was increased. After 12 months of oral refeeding, labeling index, villus height, and crypt depth were similar to those of controls. The patient with the short bowel showed a number of cells per unit length of villus and crypt significantly greater than those of the controls and of the patient who underwent shorter intestinal resection. In human duodenal mucosa, (1) hypoplasia develops after long-term total parenteral nutrition; (2) mucosal recovery occurs through an increased cell proliferation after oral refeeding; and (3) extensive small bowel resection determines the development of relative hyperplasia.

Abstract
Twenty-five patients underwent hysteroscopic resection of large symptomatic intrauterine fibroids. Patients were divided into one of three groups: those with pedunculated myomas (G0), those with intramural extension less than 50% (G1), and those with fibroids with intramural extension more than 50% (G2). In the first group (7 patients) the age ranged from 42-52 years (mean age 48 years), the operating time ranged from 15-60 min. (mean time 27 minutes), and the amount of fluid used for irrigation ranged from 1000-10000 ml (mean fluid 4400 ml). Four of the seven patients had concomitant endometrial polyps. Follow-up ranged from 3-32 months (mean 21 months), one patient was lost, and the success rate in 6 was 100%. In the second group (9 patients) the age ranged from 30-54 years (mean age 43.5 years), the operating time ranged from 35-90 minutes (mean time 62 minutes), and the amount of fluid used ranged from 2800-12500 ml (mean fluid 7150 ml). In one case endometrial ablation was associated. Two patients (45 and 54 years) had histopathological diagnosis of malignancy (endometrial stromal nodule and stromal myoma) and required hysterectomy. No residual stromal nodule was found in the uterus following hysteroscopy resection in one case. Follow-up ranged from 6-38 months (mean 20 months), two patients was lost and one had repeat hysteroscopic procedure. Four of the nine patients had a successful outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Home parenteral nutrition (HPN) was used for the treatment of 18 patients with chronic intestinal failure (CIF): short bowel syndrome (9), extensive intestinal disease (4), motility disorder (4), entero-enteric fistulas (1). The underlying diseases were: chronic inflammatory (7), mesenteric vascular (4), scleroderma (2), pseudo-obstruction (2), malignancy (2), radiation enteritis (1). HPN was more effective on protein-calorie nutritional status than on fluid and electrolyte balances. About two-thirds of the patients achieved full or partial social rehabilitation. During the 6 months before HPN, there were 20 hospitalizations (mean stay: 55 days). During HPN (mean length of treatment: 22 months/patient) there were 16 hospitalizations (mean stay: 22 days), 8 of which were caused by HPN complications (sepsis and deep vein thrombosis; overall incidence of catheter-related complications: 0.411 per patient-year). Bone demineralization, liver abnormalities and biliary stones developed, respectively, in 57%, 28% and 11% of the cases. The underlying intestinal condition played a role in their pathogenesis. The annual cost of HPN ranged from 40 (Hospital Pharmacy Service) to 80 (commercial firm) million lire per patient. To sum up, HPN improves the nutritional status and the quality of life of patients with CIF, and the risk of complications is acceptable. The medical and social advantages are considered to offset the cost of the technique.

Abstract
BACKGROUND Upper gastrointestinal motility is regulated by the presence of nutrients in the distal gut. The present study evaluated whether lipid-induced ileal brake on gastric emptying (1) can be elicited by low fat concentrations; (2) is a dose-dependent phenomenon; and (3) is related to gastrointestinal peptide release. METHODS Seven patients were studied in the defunctionalized stage of total colectomy, on three separate occasions. On each study day, patients ate a meal labeled in the solid component; 30 minutes later, one of the following solutions was randomly infused into the ileal pouch: 0.9% saline, 2% oleic acid, and 20% oleic acid. Plasma concentrations of peptide YY (PYY), enteroglucagon, neurotensin, and motilin were measured. RESULTS Both oleic acid solutions slowed gastric emptying compared with saline (P < 0.001), the effect being dose dependent (P < 0.001). Ileal infusions did not modify neurotensin and enteroglucagon levels but induced a dose-dependent increase of PYY (P < 0.01) and a borderline decrease of motilin (P = 0.05) levels. Slower rates of gastric emptying were related to increased plasma concentrations of PYY (r = 0.615; P < 0.05). CONCLUSIONS This study shows that (1) the ileal brake on gastric emptying can be evoked by low doses of lipids in the distal ileum; (2) the delay of gastric emptying is related to the release of PYY; and (3) both phenomena are dose dependent.

Abstract
The relationship between intestinal permeability to an oral dose (100 mu Ci) of [51CR]EDTA and the inflammatory activity of Crohn's disease was studied in 63 adult patients (32 unresected and 31 resected) who underwent 162 evaluations. The results of the [51CR]EDTA test were compared with the serum levels of the acute-phase reactant proteins (APRP) and with the result of the [111In]leukocyte scanning, respectively, as an indirect and direct method to assess intestinal inflammation. In a group of healthy adult controls, the upper normal value for the 24-hr urinary [51CR]EDTA excretion was 3.61 (97.5% percentile) and the mean coefficient of variation was 21%. Sensitivity and specificity of the [51CR]EDTA test in identifying active inflammation expressed by increased serum levels of APRP were, respectively, 97% and 54% in the unresected group and 68% and 52% in the resected group of patients. The low specificity of the test was due to the presence of increased [51CR]EDTA urinary excretion in about half the cases with normal serum levels of APRP. The [111In]leukocyte scanning was performed in a subgroup of 11 patients (three unresected and eight resected) with normal serum levels of APRP, six with increased and five with normal [51CR]EDTA urinary excretion. All six patients with increased intestinal permeability had a positive 111In image of mild to moderate degree of activity. A positive 111In scan was present in two of the five patients with normal permeability; these were two resected patients.(ABSTRACT TRUNCATED AT 250 WORDS)
