In this study the Authors have evaluated the use of cefonicid in "short-term" post-surgical prophylaxis in gynecology. No effects, nor alteration to hematochemical parameters related to the administration of this medicine have been observed and the analysis of data shows that the use of cefonicid contributes to reducing the incidence of post-surgical infections in hospital in a cure group compared to a control group.  相似文献

Background and aims

Familial hypercholesterolemia (FH) is underdiagnosed and public cholesterol screening may be useful to find new subjects. In this study, we aim to investigate the prevalence of FH patients in a hospital screening program and evaluate their atherosclerotic burden using intima-media thickness (IMT).

Methods and results

We screened 1575 lipid profiles and included for genetic analysis adults with a low-density lipoprotein (LDL) cholesterol >190 mg/dL and triglycerides <200 mg/dL and first-degree child relatives with LDL cholesterol >160 mg/dL and triglycerides <200 mg/dL. The diagnosis of FH was presumed by Dutch Lipid Clinic Network (DLCN) criteria and confirmed by the presence of the genetic variant. Mean common carotid intima-media thickness (IMT) was assessed using consensus criteria. After confirming LDL cholesterol value and excluding secondary hypercholesterolemia, 56 subjects with a DLCN ≥4 performed genetic analysis. Of these, 26 had an FH genetic variant. The proportion of patients with a mutation having a DLCN score of 6–8 was 75%; in individuals with a DLCN score >8 it was 100%. Mean IMT was higher in FH patients compared to non FH (0.73 [0.61–0.83] vs 0.71 [0.60–0.75] mm, p < 0.01). Moreover, we detected two mutations not previously described. Finally, simple regression analysis showed a correlation of IMT with LDL cholesterol >190 mg/dL and corneal arcus (p < 0.01 and p < 0.001, respectively).

Conclusions

A hospital screening was useful to detect FH subjects with increased atherosclerosis. Also, next-generation sequencing was able to detect new FH mutations.  相似文献

To evaluate whether, in a sample of patients radically treated for colorectal carcinoma, the preoperative determination of the carcinoembryonic antigen (p-CEA) may have a prognostic value and constitute an independent risk factor in relation to disease-free survival. The preoperative CEA seems to be related both to the staging of colorectal neoplasia and to the patient''s prognosis, although this—to date—has not been conclusively demonstrated and is still a matter of intense debate in the scientific community. This is a retrospective analysis of prospectively collected data. A total of 395 patients were radically treated for colorectal carcinoma. The preoperative CEA was statistically compared with the 2010 American Joint Committee on Cancer (AJCC) staging, the T and N parameters, and grading. All parameters recorded in our database were tested for an association with disease-free survival (DFS). Only factors significantly associated (P < 0.05) with the DFS were used to build multivariate stepwise forward logistic regression models to establish their independent predictors. A statistically significant relationship was found between p-CEA and tumor staging (P < 0.001), T (P < 0.001) and N parameters (P = 0.006). In a multivariate analysis, the independent prognostic factors found were: p-CEA, stages N1 and N2 according to AJCC, and G3 grading (grade). A statistically significant difference (P < 0.001) was evident between the DFS of patients with normal and high p-CEA levels. Preoperative CEA makes a pre-operative selection possible of those patients for whom it is likely to be able to predict a more advanced staging.Key words: Colorectal carcinoma, Preoperative carcinoembryonic antigen, Disease-free survival, Independent prognostic factorIn the world today, more than 1 million cases of patients with colorectal neoplasia are identified each year. Forty percent of these will have a poor prognosis for which targeted therapeutic strategies could most likely be more effective.13 For this reason, finding prognostic factors that are early, reliable, and related to the extent of the tumor is of the utmost importance. Among these, the most that are considered even to this day are T and N parameters.1,2,4,5 Less relied upon, however, is the M parameter, which is often understaged due to inadequate pretreatment diagnostic methods.6 However, these parameters, which are available to us only after surgery, do not represent the gold standard. In fact, the prognosis of patients with the same staging is often various and that the need to continually implement ever-changing variables in an already excessively fragmented staging is still present.2,4,7–9Recently, in light of these needs, great attention has been paid to the study of molecular and genetic markers. At present, these markers still have not found a regular application due to the complexity of their determination, the difficulty of standardization and, last but not least, the low cost-benefit ratio.1,3,4,9,10With this in mind, in our opinion, the carcinoembryonic antigen (CEA) maintains its position, as for over 30 years it has continued to be the most widely used marker11 and whose validity, with regard to colorectal follow-up, has been sanctioned by leading organizations such as the American Society of Clinical Oncology (ASCO)12 and the European Group on Tumor Markers.13 Moreover, as Herrera14 and Wanebo15 had already reported by the end of the ‘70s, the preoperative determination of the CEA (p-CEA) seems to be related both to the staging of colorectal neoplasia and to the patient''s prognosis. However, to date, none of this has been conclusively demonstrated and is still a matter of intense debate both in prestigious scientific journals4,7,11,1621 as well as in different guidelines.22The American Society of Clinical Oncology itself, if on the one hand suggests using the determination of the CEA in the preoperative staging thus justifying a worse prognosis when increased,12 on the other, does not validate using the p-CEA in the determination of an adjuvant or neo-adjuvant therapeutic strategy.23Regarding this issue, we believe it still pertinent to evaluate whether in a sample of patients radically treated for colorectal carcinoma, the determination of the p-CEA may have a prognostic value and constitute an independent risk factor in relation to disease-free survival (DFS).  相似文献

The Authors, after a careful examination of the literature on endometrial hyperplasias, review the results of a preliminary study on 15 patients affected with postmenopausal metrorrhagia, cured by Danazol (200 mg/die) through 90 consecutive days. Also recognizing the best tolerance to the drug and the low incidence of the side effects, they think the results obtained by Danazol need further confirmation by more protracted controls.  相似文献

The Authors have been investigating the behaviour of ceftriaxone in gynecological surgery employing 1 g of the drug through intravenous injection an hour before the operation, after executing a cutaneous pomphus the night before. They obtained satisfactory results since out of 25 cases analyzed nowhere had they to intervene with other antibiotics. The drug, despite the 15 cases of infectious pathology observed, has been showing great tolerance and an utmost ease and usefulness of usage.  相似文献

A case of extrauterine pregnancy is reported. After a short review of the literature on the subject, personal experience of early diagnosis is reported and importance is attributed in IUD carriers to menstrual dysrhythmia and pelvic pain. For correct early diagnosis, such symptomatology must be integrated with laboratory tests and pelvic echography.  相似文献
