Pepsinogen is one component of the gastric juice which participes in the digestion. This macromolecule enters the blood circulation in a small measurable quantities in healthy subjects. Therefore, blood pepsinogen is claimed to be an indicator of the integrity of the gastric mucosa. This paper was written to review the use of porcine in the diagnostic of stomach ulcers and Hyostrongylus rubidus infection. The methods of measurement of blood pepsinogen and the diagnostic values are discussed. [less ▲]

The aim of the PREVOS study (PREVention Of early postmenopausal bone loss by Strontium ranelate) and the STRATOS study (STRontium Administration for Treatment of OSteoporosis) was to determine the minimum dose at which strontium ranelate (SR) is effective in, respectively, the prevention of bone loss in early postmenopausal nonosteoporotic women and the treatment of postmenopausal vertebral osteoporosis. Both studies were randomized, double-blind, placebo-controlled, dose-finding studies in parallel groups and lasted 2 years. In the PREVOS study, 160 early postmenopausal women were randomized to receive placebo, SR 125 mg/day, 500 mg/day or 1 g/day. In the STRATOS study, 353 osteoporotic postmenopausal women with at least one previous vertebral fracture and a lumbar T-score < -2.4 were randomized to receive placebo, SR 500 mg/day, 1 g/day or 2 g/day. In both studies, the primary efficacy parameter was lumbar bone mineral density (BMD) measured by dual-energy X-ray absorptiometry. Secondary efficacy criteria included incidence of new vertebral deformities (in the STRATOS study only) and biochemical markers of bone metabolism. In the PREVOS study, the increase in lumbar BMD from baseline in the 1 g/day group (+ 5.53%) was significantly different from the decrease in the placebo group (p < 0.001). In the STRATOS study, the annual increase in lumbar BMD in the 2 g/day group (+7.3% per year) was significantly higher than in the placebo group (p<0.001). There was a significant reduction in the number of patients experiencing new vertebral deformities in the second year of treatment in the 2 g/day group (relative risk: 0.56; 95% confidence interval: 0.35, 0.89). In both studies, there was a significant increase in the bone formation marker (bone alkaline phosphatase) in the higher-dose group. Urinary excretion of the marker of bone resorption (cross-linked N-telopeptide) was lower with SR than with placebo in the STRATOS study. SR was very well tolerated in both studies. The minimum dose at which SR is effective in preventing bone loss in early postmenopausal nonosteoporotic women and in the treatment of postmenopausal osteoporosis is 1 g/day and 2 g/day, respectively.

BACKGROUND: Relapse after treatment of Hodgkin's disease (HD) is usually identified as a result of the investigation of symptoms. We undertook this study to examine the value of whole-body positron emission tomography (PET) for the detection of preclinical relapse. PATIENTS AND METHODS: Thirty-six patients underwent 2-[fluorine-18]fluoro-2-deoxy-D-glucose ((18)F-FDG) PET at the end of treatment and than every 4-6 months for 2-3 years after the end of polychemotherapy and/or radiotherapy. In those cases of abnormal (18)F-FDG accumulation a confirmatory study was performed 4-6 weeks later. RESULTS: One patient had residual tumor and four patients relapsed during a follow-up of 5-24 months. All five events were correctly identified early by (18)F-FDG PET. Residual tumor or relapse was never first diagnosed based on clinical examination, laboratory findings or computed tomography (CT) studies. Two patients presented B symptoms and the three others were asymptomatic at the time of residual disease or relapse. Confirmation of residual disease or relapse was obtained by biopsy in four patients 1, 1, 5 and 9 months after PET and by unequivocal clinical symptoms and CT studies in one patient 3 months after PET. False-positive (18)F-FDG PET studies incorrectly suggested possible relapse in six other patients, but the confirmatory PET was always negative. Our study also provides important information about physiological (18)F-FDG uptake in the thymus. CONCLUSIONS: Our data suggest the potential of (18)F-FDG PET to detect preclinical relapse in patients with HD. This could help identify patients requiring salvage chemotherapy at the time of minimal disease rather than at the time of clinically overt relapse. Further studies are warranted to determine the impact of PET on treatment management and outcome. In fact, the aim of follow-up procedures is not only to detect preclinical relapse but mainly to obtain better results by starting salvage treatment earlier. A cost-benefit analysis will also be necessary before (18)F-FDG PET can be used routinely in the follow-up of patients with HD. [less ▲]

Acetaldehyde, the first ethanol metabolite, was recently suggested to play a major role in many behavioral effects of ethanol. However, no studies have directly investigated the behavioral effects of acetaldehyde after acute administration. Therefore, the aim of the present study was to characterize the locomotor, hypnotic and ataxic effects of acetaldehyde in C57BL/6J mice. Various acetaldehyde doses (0-300 mg/kg) were injected intraperitoneally and their effects were investigated with several classical behavioral tests. The locomotor effects of acetaldehyde were measured in standard activity boxes. In addition, the loss of righting reflex was used to assess the hypnotic effects of acetaldehyde. Finally, the ataxic effects of acetaldehyde were studied with the horizontal wire test. The results show that acetaldehyde induced a significant hypolocomotor effect at 170 mg/kg and higher doses. In addition, the hypnotic effects of acetaldehyde were evidenced by a loss of righting reflex in doses between 170 and 300 mg/kg. However, the locomotor and hypnotic effects of acetaldehyde were very brief relative to what is observed after ethanol administration. After 170 mg/kg acetaldehyde, normal activity was recovered in less than 30 minutes and the loss of righting reflex lasted only an average of 6.14 ± 1.29 minutes after the administration of 300 mg/kg acetaldehyde, the highest testable dose before lethality. Ataxic effects were observed with lower doses that did not significantly affect locomotor activity. These results show that acetaldehyde, like ethanol, possesses sedative, hypnotic and ataxic properties and therefore indicate that the first product of ethanol metabolism might be involved in these ethanol effects.

It has been postulated that a number of central effects of ethanol are mediated through the action of its first metabolite, acetaldehyde. In particular, acetaldehyde might be involved in the anxiolytic and hedonic effects of ethanol and is therefore believed to play an important role in alcohol abuse. In agreement with this assumption, previous studies indicated that acetaldehyde is mainly reinforcing in rats, which have been shown to readily self-administer acetaldehyde both peripherally and centrally. However, the hedonic effects of acetaldehyde have never been tested in mice, and the possible amnesic and anxiolytic effects of acetaldehyde remain to be elucidated. Therefore, the present studies were aimed at characterizing the anxiolytic, hedonic and amnesic effects of acetaldehyde after its acute peripheral administration to C57BL/6J mice. The effects of intraperitoneal acetaldehyde (0-300 mg/kg) injections were assessed in several classical behavioral tests. The anxiolytic effects were tested with the elevated plus maze, the hedonic effects with the place conditioning procedure and the amnesic effects with the passive avoidance apparatus. Our results show that acetaldehyde dose-dependently altered memory consolidation as evidenced by a reduced performance in the passive avoidance test when acetaldehyde was injected immediately after training at doses between 100 and 300 mg/kg. The elevated plus-maze showed that acetaldehyde, in contrast to ethanol, does not possess anxiolytic properties. Finally, the results of the place conditioning experiment confirmed that acetaldehyde displays significant hedonic properties. The present results add further support to the role of acetaldehyde in ethanol amnesic and hedonic effects but interestingly suggest that acetaldehyde is not involved in ethanol anxiolytic effects.

The phase 3 program for strontium ranelate, a new oral agent in the treatment of women with postmenopausal osteoporosis, was aimed to assess the efficacy and safety of the daily oral dose of 2 g. This program was conducted in 12 countries, involved 75 centers, and was structured in 3 studies: FIRST (Fracture International Run-in for Strontium ranelate Trial), SOTI (Spinal Osteoporosis Therapeutic Intervention study) and TROPOS (TReatment Of Peripheral OSteoporosis). FIRST, a run-in open study, was designed to start the normalization of the calcium and vitamin D status of the patients, check all entry criteria, and ensure inclusion of a sufficient number of well-motivated patients in either one of the two therapeutic intervention protocols, SOTI or TROPOS: FIRST included 9,196 patients. SOTI and TROPOS were prospective, randomized, double-blind clinical trials comparing, in two parallel groups, the daily oral dose of 2 g of strontium ranelate with placebo, the patients of both groups receiving calcium and vitamin D according to their own deficiencies. The main objective of SOTI and TROPOS was to demonstrate a reduction in the incidence of postmenopausal women experiencing a new osteoporotic fracture (vertebral fracture in SOTI and nonvertebral fracture in TROPOS) over a 3-year treatment period, the total duration of the studies being 5 years. SOTI included 1,649 women with at least one osteoporotic vertebral fracture at inclusion and a lumbar BMD less than or equal to 0.840 g/cm(2). TROPOS included 5,091 women with a femoral neck BMD less than or equal to 0.600 g/cm(2). The phase 3 program for the clinical development of strontium ranelate in women with postmenopausal osteoporosis is a long-term program with the main statistical analysis after 3 years of treatment. Its aim is to demonstrate the effect of strontium ranelate on the axial and appendicular skeleton as well as its tolerability in osteoporotic patients with replete calcium and vitamin D stores.

BACKGROUND: It is commonly stated that risk factors for postoperative nausea are the same as for vomiting. The authors designed a prospective study to identify and differentiate the risk factors for postoperative nausea and vomiting in various surgical populations in a clinical audit setting. METHODS: The study included 671 consecutive surgical inpatients, aged 15 yr or more, undergoing various procedures. The study focused on postoperative nausea visual analog scale scores every 4 h and vomiting episodes within 72 h. Both vomiting and retching were considered as emetic events. Patient-, anesthesia-, and surgery-related variables that were considered to have a possible effect on the proportion of patients experiencing postoperative nausea and/or vomiting were examined. The bivariate Dale model for binary correlated outcomes was used to identify selectively the potential risk factors of postoperative nausea and vomiting. RESULTS: Among the 671 patients in the study, 126 (19%) reported one or more episodes of nausea, and 66 patients (10%) suffered one or more emetic episodes during the studied period. There was a highly significant association between the two outcomes. Some risk factors were predictive of both nausea and vomiting (female gender, nonsmoking status, and general anesthesia). History of migraine and type of surgery were mainly responsible for nausea but not for vomiting. The predictive effect of risk factors was controlled for postoperative pain and analgesic drugs. CONCLUSION: This study shows that differences exist in risk factors of postoperative nausea and vomiting. These could be explained by differences in the physiopathology of the two symptoms. [less ▲]

Since the 1st April 2002, the European Union has extended the Transmissible Spongiform Encephalopathy testing in ruminants by including sheep and goats in the survey studies. In small ruminants, presence of the agent of Bovine Spongiform Encephalopathy was demonstrated in tonsils, so these are considered as specified risk materials. This article gives an overview of the anatomical localisation and histological structure of the tonsils in small ruminants. Anatomically, 6 different tonsils can be distinguished: 3 are located in the oropharyngeal tract (tonsilla palatina, tonsilla lingualis, tonsilla veli palatini), 2 in the nasopharyngeal tract (tonsilla pharyngea and tonsilla tubaria), and one in the laryngopharyngeal tract (tonsilla paraepiglottica). Several tonsils show a cryptic overlying epithelium (cryptic tonsil) whereas other don't (non-cryptic tonsil). Several immunological features of the tonsils are described. [less ▲]

The treatment of pituitary tumours strongly depends on their clinical presentation. In general, the treatment aims are reducing tumour volume and/or decreasing hormone hypersecretion. It relies on single or a combination of three different methods: surgery, medication and radiotherapy. The rationale for deciding the treatment are many but include the aggressiveness of the tumour. The aetiologies of sporadic pituitary adenomas are not fully understood. However, several causes have been identified resulting in specific familial phenotypes like multiple endocrine neoplasia type I (MEN1). MEN1 is related to mutations in the MEN1 gene, a tumour suppressor gene localized on chromosome 11q13 and which encodes menin, a 610 amino acid protein. During the last years, an evidence progressively emerged that MEN1-related adenomas were more aggressive and less responsive to therapy than their sporadic counterparts. In this article, we review the differences between sporadic and MEN1-related adenomas and suggest specific ways of treatment and follow-up for MEN1-related tumours. [less ▲]

The paper analyses the ability of thin-film tactile sensors in providing information during static compression tests of ‘Jonagold’ apples (Malus pumila) of different ripeness stages. Such sensors are able to measure the contact surface and the interfacial pressure distribution during compression of fruits, this latter being characterised by suitable mathematical parameters. Results of compression tests between two flat steel plates are presented. The differentiated evolution of the pressure distribution according to the fruit maturity is pointed out. Ability of the sensor in evaluating the firmness is also discussed. [less ▲]
