BackgroundA careful assessment of a living donor is mandatory to minimize the short- and long-term risk related to kidney donation. In this study, we evaluated the incidence of incidental findings (IFs) in a large population of potential living kidney donors. Moreover, this study evaluated if the presence of IFs could influence the chance of living kidney donation and post-transplant outcomes.MethodsOne hundred and sixty consecutive potential prospective living kidney transplant donors, who underwent a multidetector computed tomography angiography (MDCTA), were included in the study. An IF was defined as an incidentally discovered mass or lesion, detected by computed tomography angiography during the imaging evaluation of potential living donors. Clinical outcomes of living donors with IF were compared with those without IF.ResultsIn 10 patients (6.2%) an incidental finding was detected at MDCTA assessment. Among the 10 patients presenting with an IF, 7 patients (4.3%) were excluded from the living donation: 2 patients with an adrenal lesion, 3 patients with cancer, and 2 patients with a large (>8 cm) renal cyst. Graft and patient survival of kidney transplant recipients of donors with IFs were not significantly different to those receiving a kidney from living donors without IFs.ConclusionsIncidental findings are frequently discovered during living kidney donor evaluation. Whereas most are asymptomatic or not clinically relevant, predonation screening could identify potentially life-threatening diseases at an earlier stage, allowing for a more radical treatment. 相似文献
Hypoactive sexual desire disorder (HSDD) is a common multidimensional condition which is characterized by a decrease in sexual desire that causes marked personal distress and/or interpersonal difficulty. There are a number of potential causes and contributing factors to HSDD and a balanced approach comprising both biological and psycho-relational factors is mandatory for accurate diagnosis and tailored management in clinical practice. It is clearly evident that sex hormones play a crucial role in modulating sexual response during the entire reproductive life span of women. On the other hand, a better understanding of the neurobiological basis of sexual desire supports the idea that selective psychoactive agents may be proposed as non-hormonal treatments to restore the balance between excitatory and inhibitory stimuli leading to a normal sexual response cycle. However, there are currently no approved pharmacological treatments for premenopausal women with HSDD, while transdermal testosterone is approved in Europe for post-menopausal women who experience HSDD as a result of a bilateral oophorectomy. That being so, the ideal clinical approach remains to be established in term of efficacy and safety and further research is needed to develop specific pharmacotherapies for individualized care of women with sexual dysfunction of any age. 相似文献
PURPOSE: To prospectively determine the accuracy of combination positron emission tomography-computed tomography (PET/CT) in lymph node staging in patients with early-stage cervical cancer, with histopathologic results as the reference standard. MATERIALS AND METHODS: The study was institutional review board approved, and all patients gave informed consent. Forty-seven consecutive women aged 29-71 years with clinical stage IA or IB cervical carcinoma were included in the study. All 47 patients were scheduled for radical hysterectomy with pelvic lymph node dissection. Before surgery, all patients underwent fluorine 18 fluorodeoxyglucose (FDG) PET/CT. PET/CT findings were interpreted by two readers in consensus and then compared with histopathologic results. At histopathologic examination, the dissected lymph nodes were classified as nonmetastatic or metastatic. RESULTS: Fifteen (32%) patients had metastatic lymph nodes at histopathologic examination, and 32 (68%) had no histopathologically confirmed nodal metastasis. Of the total 1081 lymph nodes histopathologically sampled, 18 were found to be positive for malignant cells. The overall node-based sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of PET/CT were 72% (13 of 18), 99.7% (1060 of 1063), 81% (13 of 16), 99.5% (1060 of 1065), and 99.3% (1073 of 1081), respectively. Corresponding values for PET/CT-based diagnosis of lymph nodes larger than 0.5 cm in diameter were 100% (13 of 13), 99.6% (675 of 678), 81% (13 of 16), 100% (675 of 675), and 99.6% (688 of 691), respectively. The overall patient-based sensitivity, specificity, PPV, NPV, and accuracy of PET/CT were 73% (11 of 15), 97% (31 of 32), 92% (11 of 12), 89% (31 of 35), and 89% (42 of 47), respectively. CONCLUSION: PET/CT proved to be valuable for lymph node staging in patients with early-stage cervical cancer, with short-axis diameter greater than 0.5 cm being the size threshold for accurate depiction of metastatic nodes. 相似文献
Although dual diagnosis has been a topic of great scientific interest for a long time, few studies have investigated the personality traits that characterize patients suffering from substance use disorders and co-occurring personality disorders through a dimensional approach. The present study aimed to evaluate structural personality profiles among dual-diagnosis inpatients to identify specific personality impairments associated with dual diagnosis.
Methods
The present study involved 97 participants divided into three groups: 37 dual-diagnosis inpatients, 30 psychiatric outpatients and 30 nonclinical controls. Dimensions of personality functioning were assessed and differences between groups were tested using Kernberg's dimensional model of personality.
Results
Results showed that dual diagnosis was associated with the presence of difficulties in three main dimensions of personality functioning. Dual-diagnosis inpatients reported a poorly integrated identity with difficulties in the capacity to invest, poorly integrated moral values, and high levels of self-direct and other-direct aggression.
Conclusions
The present study highlighted that a dimensional approach to the study of dual diagnosis may clarify the personality functioning of patients suffering from this pathological condition. The use of the dimensional approach could help to advance research on dual diagnosis, and it could have important implications on clinical treatment programs for dual-diagnosis inpatients. 相似文献
To investigate clinical factors associated to lymphnodal metastasis load in patients who underwent to radical prostatectomy (RP) and extended pelvic lymph node dissection (ePLND).
Materials and methods
Between November 2014 and December 2019, ET was measured in 617 consecutive patients not under androgen deprivation therapy who underwent RP and ePLND. Lymphnode invasion (LNI) was codified as not present (N?=?0) or with one (N?=?1) or more than one metastatic node (N?>?1). The risk of multiple pelvic lymph node metastasis (N?>?1, mPLNM) was assessed by comparing it to the other two groups (N?>?1 vs. N?=?0 and N?>?1 vs. N?=?1). Then, we assessed the association between ET and lymphnode invasion for standard predictors, such as PSA, percentage of biopsy positive cores (BPC), tumor stage greater than 1 (cT?>?1) and tumor grade group greater than two (ISUP?>?2).
Results
Overall, LNI was detected in 70 patients (11.3%) of whom 39 (6.3%) with N?=?1 and 31 (5%) with N?>?1. On multivariate analysis, ET was inversely associated with the risk of N?>?1 when compared to both N?=?0 (odds ratio, OR 0.997; CI 0.994–1; p?=?0.027) as well as with N?=?1 cases (OR 0.994; 95% CI 0.989–1.000; p?=?0.015).
Conclusions
In clinical PCa, the risk of mPLNM was increased by low ET levels. As ET decreased, patients had an increased likelihood of mPLNM. Because of the inverse association between ET and mPLNM, higher ET levels were protective against aggressive disease. The influence of locally advanced PCa with high metastatic load on ET levels needs to be explored by controlled trials.
Inflammatory breast cancer is a rare and aggressive form of breast cancer. Venous thromboembolism is often related to cancer conditions but this report presents a case in which the thromboembolic event predicted the diagnosis of cancer. A 48-year-old female was admitted with the evidence of acute right axillary vein thrombosis. There was also erythema and edema of the skin of the right breast. Further evidence revealed a case of inflammatory breast cancer. The patient underwent anticoagulant therapy, and neoadjuvant systemic chemotherapy was initiated. The patient underwent extensive unilateral mastectomy following neoadjuvant chemotherapy. Follow-up (after 2 months of anticoagulation therapy for deep vein thrombosis) revealed recanalization of the right axillary vein, without evidence of residual thrombus. A case of acute vein thrombosis as the first manifestation of breast cancer may delay the diagnosis and subsequent appropriate treatment. 相似文献
BackgroundLaparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure, while laparoscopic adjustable gastric banding (LAGB) has been for a decade one of the most popular interventions for weight loss. After LSG and LAGB, some patients may require a second surgery due to weight regain or late complications. One anastomosis gastric bypass (OAGB) is a promising bariatric procedure, which provides effective long-term weight loss and has a favorable effect on type 2 diabetes.ObjectivesTo retrospectively analyze data from 10 Italian centers on conversion from LAGB and LSG to OAGB.SettingHigh-volume centers for bariatric surgery.MethodsProspectively collected data from 10 high-volume centers were retrospectively reviewed. Body mass index (BMI), percentage of excess BMI loss, reasons for redo, remission from co-morbidities (hypertension, diabetes, gastroesophageal reflux, and dyslipidemia), and major complications were recorded.ResultsThree hundred patients were included in the study; 196 patients underwent conversion from LAGB to OAGB and 104 were converted from LSG. BMI was 45.1 ± 7 kg/m2 at the time of first intervention, 41.8 ± 6.3 kg/m2 at redo time, and 30.5 ± 5.5 kg/m2 at last follow-up appointment. Mean percentage of excess BMI loss was 13.2 ± 28.2 at conversion and 73.4 ± 27.5 after OAGB. Remission rates from hypertension, diabetes, gastroesophageal reflux, and dyslipidemia were 40%, 62.5%, 58.7% and 52%, respectively. Mean follow-up was 20.8 (range, 6–156) months and overall complications rate was 8.6%.ConclusionOur data show that OAGB is a safe and effective revisional procedure after failed restrictive bariatric surgery. 相似文献
Venous ulcers are common, especially in the elderly, accounting for more than 50% of all lower extremity ulcers with important socioeconomic problems. Improving extracellular matrix functioning, by heparin administration, seems to be a way to support wound healing. A total of 284 patients with venous ulcers were recruited in a 4‐year period. All patients were subjected to the most appropriate treatment after considering their preference (compression therapy followed or not by vein surgery). Patients were randomised into two groups of 142 persons in each (group A and group B as cases and controls, respectively). Patients of group A, in addition to the basic treatment as described earlier, received administration of nadroparin 2850 IU/0.3 ml through subcutaneous injection once a day for 12 months, whereas group B patients received basic treatment alone. Healing was assessed by means of direct ulcer tracing with computerised planimetry. Group A showed a healing rate of 83·80% at 12 months, whereas that of group B was 60·56%. Results by age group surprisingly showed that the group of older patients took the most advantage from long‐term treatment with low molecular weight heparin; this group also had lowest recurrence rate. 相似文献
Prolidase loaded chitosan nanoparticles were set up in order to suggest an innovative therapeutic approach for Prolidase Deficiency (PD), a rare autosomal inherited disorder of the connective tissue. The satisfactory drug loading efficiency (42.6+/-2.1%) as well as the suitable physical characteristics (mean diameter of 365.5+/-35.1nm and a positive zeta-potential of 17.94+/-0.12mV) was achieved. In order to verify the compatibility of the chitosan nanoparticles with cells, the influence of the nanoparticles on the growth and the viability (MTT assay) of cultured skin fibroblasts were determined: the nanoparticles showed a good biocompatibility up to 5mug of chitosan/10,000 fibroblasts. Uptake of chitosan nanoparticles by fibroblasts was verified by confocal microscopy using FITC-labelled chitosan nanoparticles. The ex vivo experiments were performed by incubating different amounts of prolidase loaded chitosan nanoparticles with skin human fibroblasts from PD patients for scheduled times. The restored prolidase activity was quantitatively monitored by a capillary electrophoretic method and confirmed by cells morphological observations. Standing from the nanoparticles internalization, the enzymatic activity was progressively restored reaching the best value (about 66%) after 5 days of co-incubation. Moreover, prolidase loaded chitosan nanoparticles permitted to restore prolidase activity in PD fibroblasts for a prolonged period of time (8 days). 相似文献
