BACKGROUND: Positron emission tomography (PET) with 18-fluorodeoxyglucose (FDG) is an accurate method for differentiating benign from malignant disease. The use of FDG-PET for the aetiological diagnosis of pleural disease was investigated in 25 patients. METHODS: PET was performed on each subject before invasive procedures were used to determine the aetiological diagnosis. The PET data were analysed by visual interpretation of coronal, sagittal, and transverse slices. RESULTS: Sixteen patients were found to have malignant pleural disease and nine had benign disease. All patients with histologically confirmed malignant disease showed FDG uptake within the pleural thickening which was intense in 14 cases and moderate in two. PET imaging showed the absence of FDG uptake and correctly categorised seven non-malignant lesions. Two patients with infectious pleural diseases showed a localised and moderate FDG uptake. CONCLUSION: Our preliminary results suggest that FDG-PET could be an effective tool for differentiating between benign and malignant pleural diseases. [less ▲]

The high frequency of familial Crohn's disease (CD) suggests a genetic predisposition. The most recent data from epidemiology and molecular biology are consistent with a multifactorial, polygenic inheritance with a possible genetic heterogeneity. The aim of our study was, first to compare familial and sporadic CD on the basis of the type and location of the disease, and age at diagnosis, and second, to evaluate among families, the concordance rate for the type and location of the disease. PATIENTS AND METHODS: 18 families with 2 (n = 16) and 3 (n = 2) affected first degree relatives were studied. They were compared to a population of 154 sporadic CD coming from the same gastroenterology unit. RESULTS: Age at diagnosis was the same in sporadic and familial CD. There was an increased frequency of ileal (p = 0.02), and fibro stenotic (p = 0.005) CD and a decreased frequency of colonic (p = 0.006) and inflammatory (p = 0.02) disease, in familial CD. There was a significant increase in concordance rate for fibrostenotic disease (p < 0.001) and a decrease for inflammatory disease (p < 0.01), among the families. The observed concordance rate for the location of the disease was not significantly different from the expected one. In conclusion, these data suggest that CD may be heterogenous and that different clinical patterns may be determined either by genetic or environmental factors. [less ▲]

Objective: To assess the proliferative activity of eutopic and ectopic endometrium throughout the menstrual cycle and its correlation to steroid receptor content. Design: The immunohistochemical use of Ki 67 was applied to investigate the proliferation index. A recently advanced stereographic computer technology was used to investigate steroid receptors. Setting: University hospital department of gynecology. Patient(s): Biopsies of eutopic endometrium, black and red peritoneal endometriotic lesions, and ovarian endometriomas were taken from infertile patients and classified according to the phase of the cycle. Result(s): In normal endometrium, the glandular proliferation index was highest during the proliferative phase and was statistically significantly reduced during the secretory phase. No proliferative activity was observed in the late secretory phase. No statistically significant differences were found between ectopic endometrium and eutopic endometrium except during the late secretory phase, when proliferative activity was still present in endometriotic tissue. The stromal proliferation index was similar in red lesions, ovarian endometriomas, and eutopic endometrium during the secretory phase. In normal endometrium, the highest concentrations of estrogen receptors (ERs) and P receptors (PRs) occurred in the epithelial and stromal cells during the late proliferative phase of the menstrual cycle. Estrogen receptor and PR content declined throughout the secretory phase. In ectopic endometrium, PR persisted in the glandular epithelium during the late secretory phase. Estrogen receptors persisted in the glandular epithelium and stroma of red peritoneal lesions and ovarian endometriomas during the late secretory phase. Conclusion(s): The high proliferative activity and the persistence of ERs and PRs in the stroma of red lesions and ovarian endometriomas emphasize the primordial role of the stroma in the development of endometriosis and suggest different mechanisms of proliferation control from those observed in eutopic endometrium.

The relationship between the dispersion conditions of silicon nitride slurries and the compaction behaviour of spray dried granules is reported in the case of two commercial powders. Two parameters have been retained: the solid loading, varied between 10 and 30 vol.% and the degree of stability of the suspension, controlled by adjustment of the pH. [less ▲]

Objective: To determine whether interstitial collagenase (matrix metalloproteinase-1), known to play a pivotal role in the initiation of menstruation, contributes to the pathogenesis of endometriosis. Design: Serial sections of peritoneal red and black endometriotic lesions, ovarian endometriotic cysts, and rectovaginal adenomyotic nodules were analyzed by in situ hybridization for the expression of matrix metalloproteinase-1 by silver staining for the integrity of the fibrillar extracellular matrix and by immunolabeling for the abundance of sex steroid receptors. Setting: Academic hospital and research laboratory. Patient(s): Premenopausal women undergoing laparoscopy for endometriosis. Intervention(s): Biopsy of endometriotic lesions, combined with endometrium whenever possible. Main Outcome Measure(s): Expression of matrix metalloproteinase-1 messenger RNA (mRNA). Result(s): Matrix metalloproteinase-1 mRNA was expressed focally in red peritoneal and ovarian endometriosis irrespective of the phase of the menstrual cycle but was not detectable in black peritoneal and rectovaginal lesions. Foci of matrix metalloproteinase-1 expression closely correlated with matrix breakdown and with the absence of P receptors in adjacent epithelial cells. Conclusion(s): Correlation of matrix metalloproteinase-1 expression with activity of endometriotic tissue suggests its involvement in tissue remodeling and bleeding, and possibly in the secondary shedding and reimplantation of endometriotic lesions.

Hysteroscopic resection of an intrauterine septum may benefit patients suffering from infertility or recurrent pregnancy loss. A partial or complete uterine septum can be easily resected using a Nd-YAG laser. If present, the vaginal septum may also be removed during the same procedure. The reproductive outcome of women treated by operative hysteroscopy for an intrauterine septum is reviewed. To avoid pregnancy in a non-communicating rudimentary horn, the removal of the horn and the homolateral tube may be performed by either bipolar coagulation or a CO2 laser. [less ▲]

The expression of members of the IGF system in a mesothelioma from a patient suffering from hypoglycemia, in term placenta and HT29 colon adenocarcinoma cells were compared. Very high levels of IGF-II mRNA and protein were detected in the mesothelioma. Moreover, half of the IGF-II protein took the high-molecular-weight form. We also analyzed the parental imprinting status and the promoter usage of the IGF-II gene. Our results showed loss of imprinting (LOI) in the mesothelioma while the imprinting was maintained in HT29 cells, expressing moderate levels of the transcript. Promoter P4 was active in the three tissues we analyzed, whereas IGF-II mRNA transcription from promoter P3 was only detected in the mesothelioma and the placenta, expressing comparably high levels of the transcript. IGF-II gene structure was identical in the analyzed tissues and cells. The type-I receptor mRNA expression was very low in the tumor. IGFBP-2, -4 and -5 mRNAs were detected in the mesothelioma, while IGFBP-2, -3 and -5 transcripts were detected in the placenta. IGFBP-1 and -6 transcripts were not detected. [less ▲]
