In this prospective study, a significant incidence of fever (47%), true bacteremia (15%), and sepsis (12%), were found in 60 cardiac patients treated with an intra-aortic balloon counterpulsation pump. The benefit of antibiotic prophylaxis in this setting should therefore be evaluated. 相似文献

Chronic hepatitis C virus (HCV) infection is associated with the development of lymphoproliferative disorders (LPDs). The aim of this investigation was to determine the prevalence and characterization of monoclonal gammopathy and benign and malignant LPDs in individuals with chronic hepatitis C. A total of 233 subjects diagnosed with chronic hepatitis C (male/female ratio: 131/102, median age; 49 years) were studied. Serum and urine were examined for the presence of a monoclonal gammopathy. A bone marrow aspirate and biopsy was obtained in individuals with a monoclonal gammopathy. Thirty-two patients (13.7%, 32 of 233) had a monoclonal gammopathy; 75% of them were benign and were not associated with malignant disorders (24 of 32) while 25% were associated with malignant LPDs or a plasma cell disorder (eight of 32). Two additional subjects without monoclonal gammopathy were diagnosed as having a malignant LPDs. The prevalence of malignant LPDs/plasma cell disorder in individuals with HCV-induced chronic liver disease was 4.3%. No difference was found in terms of disease duration, HCV genotype, viral load, alanine aminotransferase level or histopathologic score between the subjects with or without a monoclonal gammopathy. The presence of mixed cryoglobulinaemia was strongly associated with the presence of an underlying malignant disorder. Hence a monoclonal gammopathy is found in 14% of patients with chronic hepatitis C and is associated with malignant B-cell LPD in more than a quarter of such patients. The prevalence of LPDs in individuals with HCV-induced chronic liver disease is greater than that of the normal healthy population. 相似文献

The aim of this clinical trial was to evaluate the pulsatile perfusion mode in pediatric patients who had complex cardiac pathologies according to Jenkins stratifications (category 4) undergoing cardiopulmonary bypass procedures (CPB). Patients with transposition of great arteries (TGA) and ventricular septal defect (VSD) were included in this clinical study. Eighty‐nine consecutive pediatric patients undergoing open heart surgery for repair of TGA‐VSD were prospectively entered into the study and were randomly assigned to either the pulsatile perfusion group (Group P, n = 58) or the nonpulsatile perfusion group (Group NP, n = 31). There were no differences between groups in terms of demographical and intraoperative parameters. The pulsatile group needed significantly less inotropic support (P < 0.05) and had lower lactate levels (P < 0.001), higher urine output (P < 0.01), and higher albumin levels (P < 0.05). In addition, the pulsatile group had less ICU (P < 0.01) and hospital stays (P < 0.001). We conclude that the use of pulsatile flow is a better option and should be considered for repair of the complex congenital heart defects. 相似文献

Purpose:The aim of this study was to evaluate the structural and functional changes occurring in patients with branch retinal vein occlusion (BRVO) according to the distance of the affected arteriovenous (AV) crossing to the centers of the fovea and optic disc by optic coherence tomography angiography (OCTA).Methods:Forty-five patients with unilateral BRVO and 45 age- and sex-matched healthy controls were included in this retrospective observational study. Images of the macula (3 mm × 3 mm) and affected AV crossing sites were obtained by OCTA. The fovea-AV crossing distance (FAVD), optic disc-AV crossing distance (DAVD), and optic disc-fovea distance (DFD) were measured.Results:The FAVD/DFD ratio was positively correlated with the vessel density in the superficial and deep affected hemifields (r = 0.430, P < 0.05 and r = 0.308, P < 0.05, respectively) and negatively correlated with the superficial foveal avascular zone and logarithm of the minimum angle of resolution (logMAR) visual acuity (r = –0.412, P < 0.05 and r = –0.356, P < 0.05, respectively). The DAVD/DFD ratio was not correlated with the logMAR visual acuity, superficial FAZ area or vessel densities in the affected hemifield (all P > 0.05).Conclusion:The affected AV crossing site that was further away from the fovea had better visual acuity and quantitative microvascular parameters in the affected hemifields. However, this correlation was not observed for the distance between the affected AV crossing site and the optic disc. 相似文献

Plasma cell neoplasms (multiple myeloma, solitary plasmocytoma of bone and extra medullar plasmocytoma) are characterized by a monoclonal neoplastic proliferation of plasma cells. Solitary plasmocytoma of bone (SPB) is a localized form of them. SPB is most frequently seen in vertebrae and secondarily in long bones. Its presence in jaws is extremely rare and when it is seen, angulus and ramus mandible are most common sites of occurrence. Prognosis of SPB is worse than extra medullar plasmacytoma (EMP) and approximately 50% of SPB will transform to multiple myelom. A 76-year old woman consulted to our clinic with a chief complaint of slowly developed swelling in her mandible. She had an operation from caput femur because of plasmocytoma two months before. Panoramic radiography revealed a radiolucent lesion in the mandibular anterior region, 60x35 mm in dimension. Aspiration biopsy was performed and histopathological examination was reported as plasmocytoma. She was referred to the oncology department for treatment but died before the treatment finished. 相似文献

Mandibular symphyseal distraction osteogenesis (MSDO) is an alternative strategy to correct mandibular transverse deficiencies and dental crowding. Only a limited number of practitioners have reported their clinical experience and potential complications of this procedure to widen the mandible in a large case series. This study involved retrospective analysis of 40 patients who underwent mandibular symphyseal distraction osteogenesis. Three different types of distractor were used to widen the mandible: tooth-borne in 21 patients, bone-borne in 5 patients and hybrid (both bone and tooth-borne) in 14 patients. The distraction amount ranged from 7 to 11 mm (mean 7.31 mm). While 39 patients underwent successful mandibular symphyseal distraction, there was one failure. Most of the complications were experienced in bone-borne distractors, such as breakage of the distractor rod, gingival recession, secondary infection and ptosis of the chin. In the light of these findings, it is suggested that a lingually placed tooth-borne hyrax appliance is more suitable and reliable than the other distraction devices. Further larger studies are needed in order to better evaluate the effectiveness of bone-borne or hybrid devices. 相似文献

This study compared the safety and efficacy of the on-demand (OD) use of sertraline (50 mg), sertraline (100 mg) and dapoxetine (30 mg), and the daily use of sertraline (50 mg) in the treatment of patients with premature ejaculation (PE). This prospective randomised study involved 120 lifelong PE patients (intravaginal ejaculatory latency time [IELT]: <1 min; Arabic Index of Premature Ejaculation [AIPE] score: < 30) without secondary causes of PE, identified between March 2018 and May 2020. Patients were divided into 4 groups (30 patients per group) and treated for 8 weeks. Assessments were conducted using the AIPE form as a diagnostic tool. Sertraline (50 mg, daily; 196.7 ± 115.5 s) and sertraline (100 mg, OD; 173.3 ± 97.0 s) had similar IELT and AIPE scores. The latter groups had better results in comparison with sertraline (50 mg, OD; 100.5 ± 54.4 s) and dapoxetine (93.7 ± 53.5 s; p < 0.01). Sertraline (100 mg, OD) had a similar efficacy to that of sertraline (50 mg, daily) and was more effective than sertraline (50 mg, OD) and dapoxetine (30 mg, OD). Sertraline (100 mg, OD) can be considered in the treatment of lifelong PE treatment, having tolerable side effects. 相似文献
