Fructose intolerance (FI) is a widespread non-genetic condition in which the incomplete absorption of fructose leads to gastro-intestinal disorders. The crucial role of microbial dysbiosis on the onset of these intolerance symptoms together with their persistence under free fructose diets are driving the scientific community towards the use of probiotics as a novel therapeutic approach. In this study, we evaluated the prevalence of FI in a cohort composed of Romanian adults with Functional Grastrointestinal Disorders (FGIDs) and the effectiveness of treatment based on the probiotic formulation EQBIOTA® (Lactiplantibacillus plantarum CECT 7484 and 7485 and Pediococcus acidilactici CECT 7483). We evaluated the impact of a 30-day treatment both on FI subjects and healthy volunteers. The gastrointestinal symptoms and fecal volatile metabolome were evaluated. A statistically significant improvement of symptoms (i.e., bloating, and abdominal pain) was reported in FI patient after treatment. On the other hand, at the baseline, the content of volatile metabolites was heterogeneously distributed between the two study arms, whereas the treatment led differences to decrease. From our analysis, how some metabolomics compounds were correlated with the improvement and worsening of clinical symptoms clearly emerged. Preliminary observations suggested how the improvement of gastrointestinal symptoms could be induced by the increase of anti-inflammatory and protective substrates. A deeper investigation in a larger patient cohort subjected to a prolonged treatment would allow a more comprehensive evaluation of the probiotic treatment effects. 相似文献

The current study was designed to clarify whether biodegradable poly-L/DL lactide pins provide an operative alternative for fixation of Pipkin fractures. Nine patients with Pipkin fractures (one with Pipkin Type I, one with Pipkin Type II, and seven with Pipkin Type IV fractures) were treated surgically between 1996 and 2002. In all patients, the femoral head fractures were fixed with biodegradable, 2.7-mm and 2.0-mm polylactide pins. Eight patients were followed up for an average of 54.2 months. One patient died before the final followup. Eight fractures healed uneventfully. In one patient, a persisting femoral head defect led to posttraumatic arthritis requiring insertion of a femoral endoprosthesis at 1 year. The average range of motion of the affected hips of all patients at followup was 109 degrees -0 degrees -0 degrees in flexion and extension. External and internal rotation averaged 37 degrees -0 degrees -29 degrees . One patient had Brooker Grade I heterotopic ossification develop, and another had a Grade II heterotopic develop. Merle d'Aubigne and Postel ratings showed two excellent and five satisfactory results (average score, 13.1). Adverse effects from the polylactide implants were not observed. Pipkin fractures can be fixed successfully with biodegradable polylactide pins. 相似文献

ABT-335 is the choline salt of fenofibric acid under clinical development as a combination therapy with rosuvastatin for the management of dyslipidemia. ABT-335 and rosuvastatin have different mechanisms of actions and exert complementary pharmacodynamic effects on lipids. The current study assessed the pharmacokinetic interaction between the 2 drugs following a multiple-dose, open-label, 3-period, randomized, crossover design. Eighteen healthy men and women received 40 mg rosuvastatin alone, 135 mg ABT-335 alone, and the 2 drugs in combination once daily for 10 days. Blood samples were collected prior to dosing on multiple days and up to 120 hours after day 10 dosing for the measurements of fenofibric acid and rosuvastatin plasma concentrations. Coadministering 40 mg rosuvastatin had no significant effect on the steady-state Cmax, Cmin, or AUC24 of fenofibric acid (P > .05). Coadministering ABT-335 had no significant effect on the steady-state Cmin or AUC24 of rosuvastatin (P > .05) but increased Cmax by 20% (90% confidence interval: 12%-28%). All 3 regimens were generally well tolerated with no clinically significant changes in clinical laboratory values, vital signs, or electrocardiograms during the study. Results from this study demonstrate no clinically significant pharmacokinetic interaction between ABT-335 at the full clinical dose and rosuvastatin at the highest approved dose. 相似文献

A 25-year-old male patient was admitted to our clinic for abdominal pain, diarrhea, intermittent rectal bleeding and weight loss. The family history revealed two deaths due to colorectal cancer (maternal grandmother and patient's mother). The colonoscopy showed hundreds of polyps throughout the colon, and an ulcerative rectosigmoidian tumor. The diagnosis was Familial Adenomatous Polyposis (FAP). Colectomy with ileorectal anastomosis was performed. Histopathological diagnosis revealed moderately differentiated adenocarcinoma. Adjuvant chemotherapy was carried out. The patient had three brothers, without clinical symptoms. They had a colonoscopic examination for screening. Two of them were diagnosed with adenomatous polyposis - the first with classic FAP and the other one with the attenuated type (AFAP). The diagnosis of FAP can be made on the basis of either clinical or genetic criteria. When the family history, clinical features, and pathological findings are classic, the diagnosis is straightforward. Screening and prophylactic surgery are effective to prevent colorectal cancer in patients with FAP. Lifelong regular surveillance is necessary to detect and manage extracolonic lesions. 相似文献

BACKGROUNDSuperior mesenteric artery syndrome is a disease with a complex diagnosis, and it is associated with complications that make it even harder to identify. Currently, a frequent association with psychiatric disorders has been noted. Despite numerous case reports and case series, the variability of the disease has not allowed the development of protocols regarding diagnosis and management.CASE SUMMARYA 33-year-old woman presented with abdominal pain, nausea, and bile vomiting over the last 15 mo, associated with a 15-kg weight loss over the last three months. After the onset of the symptoms, the patient was diagnosed with anxiety-depressive disorder and treated appropriately. Standard examinations excluded an organic cause, and the cause of the symptoms was considered psychogenic. The persistence of symptoms, even under treatment, prompted a computer tomography angiography examination of the abdomen and pelvis. The examination identified emergence at a sharp angle of 13.7° of the superior mesenteric artery, with a reduced distance between the artery and the anterior wall of the aorta up to a maximum of 8 mm. A diagnosis of aortomesenteric clamp was established. Surgical treatment by laparoscopic duodenojejunostomy was performed. Postoperative evolution was marked by a patent anastomosis at 1 mo, with a 10-kg weight gain and improvement of the associated anxiety.CONCLUSIONThis case report underlines two major aspects. One aspect refers to the predisposition of patients with superior mesenteric artery syndrome to develop psychiatric disorders, with an excellent outcome when proper treatment is administered. The second aspect underlines the key role of a multidisciplinary approach and follow-up. 相似文献

Background: Assessing the diagnostic value of liver ultrasound image computerized analysis (USICA) for hepatic fibrosis (HF) staging in respect to the “gold standard” provided by liver biopsy (LB).Methods: Two-hundred twenty-eight patients with chronic hepatopathies were prospectively enrolled in the study. All the patients underwent LB and abdominal ultrasound (US). For quantitative US assessment of HF, an image analysis software was developed and 3 parameters were extracted by wavelet processing of the region of interest: mHLlivermHHliver, mHLlivermLLliver, and mHLlivermHLspleen. To assess the relevance of each feature, the support vector machine (SVM) classifiers were employed to discriminate between the 2 severity classes (i.e., incipient F1-F2 vs advanced F3-F4 fibrosis). The statistical significance of the HF staging was assessed using SVM classifiers, in terms of sensitivity (Se), specificity (Sp), and receiver operating characteristic (ROC) curves.Results: A cut-off value of 0.342 of mHLlivermHHliver allowed the discrimination between the incipient and advanced HF with 79.5% Se and 77.4% Sp, at an area under receiver operating characteristic (AUROC) value of 0.867 (P ˂ .001). Conclusion: The proposed USICA using wavelet filter parameters proved to be an innovative method that is useful for the initial non-invasive evaluation and quantification of HF, with the advantages of simplicity, short calculation time, accessibility, and repeatability.The mHLlivermHHliver parameter has demonstrated good accuracy in distinguishing incipient and advanced HF and can be considered an effective non-invasive imaging marker for the assessment of HF in patients with chronic hepatic disease. 相似文献

Studies using comparative genomic hybridization (CGH) indicate that portions of chromosome arm 8q from 8q12 to 8qter are present at an increased relative copy number in a broad range of solid tumors. In this study we define an ∼ 1 Mb wide region that appears to be frequently abnormal in copy number or structure in breast cancer cell lines and primary tumors. This was accomplished by fluorescence in situ hybridization (FISH) with yeast artificial chromosomes (YACs) mapped to 8q12-q22. Eleven breast cancer cell lines and ten primary tumors were analyzed. A minimal region of rearrangement was localized to the CEPH-YAC 928F9 in three breast cancer cell lines with unbalanced translocation breakpoints mapping in this region. Unbalanced translocations also were detected in two primary tumors mapping between CEPH-YAC clones 890C4 and 936B3, flanking 928F9. An increased copy number in the minimal region was detected in nine cell lines and in multiple primary tumors. This suggests the possibility that a single gene mapping to 928F9 is involved in breast cancer development or progression and may be deregulated by copy number increases in some tumors and by translocation in others. Four expressed sequence tags were mapped to YAC 928F9 and analyzed for rearrangements by Southern analysis and for abnormal expression by Northern analysis.

The phenolic antioxidant components of the grape (flavonoids and non-flavonoids) cause it to stand out. The article states the structure and main families of phenolic components found in the grape. Moderate consumption of grapes and products derived from grapes (containing polyphenols) can lead to decreased platelet aggregation as well as dilating the blood vessels. The physiological effects of consuming polyphenols derived from grapes on diabetes, raised blood-pressure or arthritis demonstrate in vivo prevention of these pathologies, with synergy if ethanols are associated with the grape polyphenols by various mechanisms. Grape polyphenols can therefore be said to have a role in preventive nutrition. 相似文献

Pill esophagitis is a rare clinical diagnosis. We report a series of two patients who experienced ulcerative esophagitis while taking doxycycline (patient 1) and alendronate (patient 2). Both patients presented with retrosternal pain, odynophagia and dysphagia. Symptoms developed after 3 days of treatment with doxycycline in patient 1 and after 3 months of treatment with alendronate in patient 2. Endoscopy revealed ulcerative lesions in the mid-esophagus, sparing the distal esophagus. Biopsies showed inflammatory infiltrate (patient 1) and ulceration and hyperplastic cells (patient 2). Patient 1 recovered completely endoscopically after discontinuation of the antibiotic and a one month course of sucralfate treatment. Patient 2 did not accept the discontinuation of alendronate therapy. She also had a course of one month treatment with sucralfate. At one, two and even at seven months after the first diagnosis, endoscopy still showed the persistence of millimetric defects of epithelisation. She is still under endoscopical survey. In conclusion, doxycycline and alendronate can cause chemical esophagitis when taken improperly. In adults and elderly patients exclusion of esophageal carcinoma by histology is necessary. Continuation of treatment with the offending drug can delay healing. Pill esophagitis is a preventable cause of morbidity that consists of giving simple advice of how and when to take medication. 相似文献
