Background/Aims-Infection with Helicobacter pylori strains harbouring the cagA gene (cagA+) is associated with an increased risk of developing peptic ulcer and gastric cancer. The aim of this study was to assess whether H pylori isolates with diVerent cagA status were present in patients with non-ulcer dyspepsia, and whether a variable cagA status is relevant to histological gastric mucosal damage and glandular cell proliferation. Methods-Well separated H pylori colonies (between 2 and 25) from primary plates, per gastric area, for each of 19 patients with non-ulcer dyspepsia were examined for cagA by hybridisation. Western blotting was used to examine both representative colonies for CagA expression and the patients' sera for antibody response to CagA. Glandular gastric cell proliferation was assessed immunohistochemically. Results-Of the 747 colonies examined, 45.3% were cagA+. All colonies from four patients were cagA+, and all colonies from two patients were cagA−. In 13 patients (68%) both cagA+ and cagA− colonies were found. CagA expression of isolates corresponded to their cagA status. H pylori strains with diVerent CagA molecular masses were present in three patients. Results based on all 19 patients studied showed that the prevalence of cagA+ colonies in areas with mucosal atrophy associated or not with intestinal metaplasia (67.9%) was significantly higher than in normal mucosa (44.7%) and mucosa from patients with chronic gastritis (44.0%) (p< 0.001). High levels of cell proliferation were associated with histological atrophy with or without intestinal metaplasia, but not with the possession of cagA by organisms colonising the same mucosal sites. Conclusions-Most patients with nonulcer dyspepsia are infected by both cagA+ and cagA− H pylori colonies. The cagA status of infecting organisms may play a role in the development of atrophy and intestinal metaplasia. (Gut 1998;42:772-778)

The laparoscopic approach has proved to be an extremely reliable procedure for benign pathologies and isolated metastases. There may yet be doubts about its use for the treatment of adrenal carcinomas preoperatively diagnosed. When surgery is performed using Harmonic Scalpel, operative time is significantly reduced and surgery is easier and less expensive. Infact use of the Harmonic Scalpel allowed the cost per operation to be reduced $70. Moreover, if surgery is performed using the nondisposable clip applier, the expenses are reduced $105.

Purpose In both preclinical and clinical settings, testosterone treatment (TTh) of hypogonadism has shown beneficial effects on insulin sensitivity and visceral and liver fat accumulation. This prospective, observational study was aimed at assessing the change in markers of fat and liver functioning in obese men scheduled for bariatric surgery. Methods Hypogonadal patients with consistent symptoms (n = 15) undergoing 27.63 ± 3.64 weeks of TTh were compared to untreated eugonadal (n = 17) or asymptomatic hypogonadal (n = 46) men. A cross-sectional analysis among the different groups was also performed, especially for data derived from liver and fat biopsies. Preadipocytes isolated from adipose tissue biopsies were used to evaluate insulin sensitivity, adipogenic potential and mitochondrial function. NAFLD was evaluated by triglyceride assay and by calculating NAFLD activity score in liver biopsies. Results In TTh-hypogonadal men, histopathological NAFLD activity and steatosis scores, as well as liver triglyceride content were lower than in untreated-hypogonadal men and comparable to eugonadal ones. TTh was also associated with a favorable hepatic expression of lipid handling-related genes. In visceral adipose tissue and preadipocytes, TTh was associated with an increased expression of lipid catabolism and mitochondrial bio-functionality markers. Preadipocytes from TTh men also exhibited a healthier morpho-functional phenotype of mitochondria and higher insulin-sensitivity compared to untreated-hypogonadal ones. Conclusions The present data suggest that TTh in severely obese, hypogonadal individuals induces metabolically healthier preadipocytes, improving insulin sensitivity, mitochondrial functioning and lipid handling. A potentially protective role for testosterone on the progression of NAFLD, improving hepatic steatosis and reducing intrahepatic triglyceride content, was also envisaged.

Our study shows that laparoscopy is feasible and safe for AIs, regardless of the preoperative probability of malignancy. The size of the AI was the only determinant for choosing a laparotomy. Further long-term studies are necessary to confirm the laparoscopic efficacy in terms of oncologic safety.

Various authors have suggested that laparoscopic adrenalectomy (LA) leads to better surgical outcomes than open surgery. The debate is still open, however, and indications and limitations of minimally invasive surgery have not been completely established. The objective of our study was to compare surgical outcomes of LA and open adrenalectomy (OA), using multivariate analysis to adjust for potential confounding factors (e.g., size of the lesion, histology). Between 1995 and June 2000 at "Careggi" Hospital in Florence, Italy patients with an indication for adrenalectomy were treated laparoscopically if the lesion was < 10 cm and there was no clinical evidence of malignancy. All 79 patients who underwent LA have been included in this study. Among 152 patients who underwent OA at "La Sapienza" University in Rome, 93 had an adrenal lesion < 10 cm and no clinical evidence of malignancy; they were selected for comparison. Multivariate analysis has been used to analyze the effect of the surgical approach (OA vs. LA) on the surgical outcome, controlling for potential confounders.Multiple logistic regression showed that there is no significant difference in intraoperative outcomes (i.e., surgical time > 2 hours, blood loss ≥ 500 ml) between patients operated on through a traditional approach and those who underwent LA. On the other hand, patients operated on laparoscopically have a significantly higher probability than the OA group of experiencing a better recovery from surgery (i.e., require less postoperative analgesics and return to normal activities earlier). The results of the present study show that, although LA does not add much benefit in terms of expected intraoperative outcomes, it dramatically speeds patients' recovery from surgery. The two approaches are complementary and should both be integrated into the technical background of all endocrine surgeons.

We report a case of bilateral intertrigo of the third and fourth interdigital spaces of the feet in a 34-year-old immunocompetent Senegalese male. A diagnosis of Fusarium solani infection was made. Systemic and topical therapy with terbinafine led to clinical but not mycological recovery. As this mould is potentially dangerous for immunodepressed subjects, early diagnosis and rigorous follow-up of skin diseases caused by this agent are advisable.
