BACKGROUND: We report here an extremely rare case of cystosarcoma phyllodes of the seminal vesicle. METHODS: A 65-year-old man presented with urinary hesitancy, frequency and constipation. Clinical examinations including two needle biopsies were performed, and the patient had undergone open surgery. RESULTS: The final pathological diagnosis was cystosarcoma phyllodes of the seminal vesicle. Seven months after the operation, a chest X-ray showed lung metastasis, and the patient died 11 months after the operation. CONCLUSION: To our knowledge, only one case of cystosarcoma phyllodes of the seminal vesicle has been previously reported. 相似文献

Background and objective: The aim of the present study was to examine clinical and other features that might allow prognostic distinctions between histological patterns in presentations with rapidly progressive interstitial pneumonia (RPIP), and to assess prognostic factors for survival. Methods: Patients with RPIP among 425 consecutive patients with diffuse lung disease, who underwent surgical lung biopsy, were studied retrospectively. The discriminatory value of clinical and investigative features for identifying disease with a better outcome was evaluated. An a priori comparison was made between diffuse alveolar damage (DAD)/usual interstitial pneumonia with DAD pattern (Group A), and organizing pneumonia/non‐specific interstitial pneumonia pattern (Group B). Results: Twenty‐eight patients (6.6%) fulfilled the criteria for RPIP. The diagnosis was Group A disease in 15 (DAD in 10, usual interstitial pneumonia with DAD in 5), and Group B disease in 13 (organizing pneumonia in 8, non‐specific interstitial pneumonia in 5). There were no significant differences in initial findings between the groups. Prognosis was significantly better for Group B patients than for Group A patients (P = 0.021). Neither BAL nor parenchymal high‐resolution CT score was indicative of therapeutic responsiveness or outcome. Distinction between Group A and Group B on the basis of disease pattern was the only significant determinant of prognosis. Conclusions: RPIP included varied histological patterns with different outcomes, and in many cases these could not be predicted using baseline clinical data. Histology was the only significant predictor of ultimate prognosis. 相似文献

Abstract Although antimitochondrial auto-antibodies are characteristically present in the serum of patients with primary biliary cirrhosis (PBC), there is a discrepancy between the positivity for antimitochondrial antibody (AMA) and that for anti-M2 auto-antibody. In an attempt to explain the discrepancy, this study investigates the relationship between the AMA titre, determined by indirect immunofluorescence, and immunoreactivity to four inner mitochondrial membrance proteins (M2 proteins) with molecular weights of 70, 50, 47, and 40 kDa in 129 patients with PBC. Antimitochondrial antibody positivity was identified in 114 (88%) of 129 patients with clinically and histologically confirmed PBC. There were no significant differences between the AMA-negative and AMA-positive groups in clinical characteristics or histologically determined disease stage. Immunoblot analysis showed that all patients had anti-M2 auto-antibodies to one or more of the four M2 proteins. Nine (60%) of the 15 AMA-negative patients had antibodies to only one M2 protein (either 70 or 47 kDa). In contrast, 34 (53%) of the 64 patients with high AMA titres ( 1: 320) had antibodies to all four M2 proteins. There was a significant rank correlation between the AMA titre and the number of antibodies to M2 proteins ( P < 0.01). These findings indicate that the AMA titre is not influenced by the immunogenicity of M2 protein but by the number of M2 proteins that elicit an antibody response and that decreased immunoreactivity to M2 proteins may induce AMA negativity in PBC serum samples. 相似文献

Objective
Acetaldehyde is the first metabolite of ethanol and is produced in the epithelium by mucosal ALDH, while higher levels are derived from microbial oxidation of ethanol by oral microflora such as Candida species. However, it is uncertain whether acetaldehyde concentration in human breath is related to oral condition or local production of acetaldehyde by oral microflora. The aim of this pilot study was to investigate the relationship between physiological acetaldehyde concentration and oral condition in healthy volunteers.Material and Methods
Sixty-five volunteers (51 males and 14 females, aged from 20 to 87 years old) participated in the present study. Acetaldehyde concentration in mouth air was measured using a portable monitor. Oral examination, detection of oral Candida species and assessment of alcohol sensitivity were performed.Results
Acetaldehyde concentration [median (25%, 75%)] in mouth air was 170.7 (73.5, 306.3) ppb. Acetaldehyde concentration in participants with a tongue coating status score of 3 was significantly higher than in those with a score of 1 (p<0.017). After removing tongue coating, acetaldehyde concentration decreased significantly (p<0.05). Acetaldehyde concentration was not correlated with other clinical parameters, presence of Candida species, smoking status or alcohol sensitivity.Conclusion
Physiological acetaldehyde concentration in mouth air was associated with tongue coating volume. 相似文献9.

Prostaglandin E1 (PGE1) has been reported to have, experimentally and clinically, a protective effect against liver damage. This effect may result from the relaxation of hepatic stellate cells, whose contraction induces vasoconstriction of hepatic sinusoids. However, prostaglandins are unstable and a new drug delivery system is necessary to administer a sufficient amount of prostaglandin to achieve a protective effect in the liver. The aim of the study is to investigate the effects of lipo-prostaglandin E1 (lipo-PGE1) which has a novel drug delivery system on the stellate cell contraction induced by endothelin-1 in vitro. Lipo-PGE1 inhibited endothelin-1-induced stellate cell contraction in concentrations of 10, 30 and 50 ng/mL. Therefore, lipo-PGE1 may show a cytoprotective effect in the liver through the relaxation of stellate cells and an increase in the hepatic sinusoidal blood flow. 相似文献
