We examined need-related and reciprocal provision of support in couples facing radical prostatectomy and its sequelae, including patients’ urinary incontinence. Partners’ reciprocal support provision to patients was assumed to drop from prior to until after patients’ surgeries and increase again in the following months, while need-related indicators were assumed to remain unique correlates throughout. In this study of German prostatectomy patients and their partners, N = 141 couples provided data on 4 measurement occasions from presurgery to 1-year postsurgery. Need-based predictors of partners’ support provision were patients’ mobilized support, such as efforts to obtain advice or comfort, and degree of postsurgery incontinence. Strength of association between partner-received and provided supports served as an indicator of reciprocal support provision. Data suggested that partners’ reciprocal support provision dropped significantly postsurgery and then increased again in the following months. This was true for emotional as well as instrumental reciprocal support provision. Findings also indicated that one need-based predictor of partners’ support provision, patients’ mobilization of support from their partners, remained a unique correlate of partners’ support provision to patients. Reciprocal support provision in couples may vary during the adaptation to illness-related functional impairment and coexist with need-oriented support provision.  相似文献

PURPOSECyclophosphamide (CY) in a dose of 2–4 g/m2 is widely used for hemopoietic progenitor stem cells mobilization. CY administration is associated with several adverse effects, including chemotherapy-induced nausea and vomiting (CINV). This study aimed to evaluate the efficacy and tolerability of granisetron transdermal system (GTDS) plus dexamethasone in the management of CINV in MM patients undergoing chemo-mobilization with CY.METHODSIn this single-center, prospective, observational, real world study, GTDS plus dexamethasone was administered to MM patients receiving chemo-mobilization based on CY 2 g/m2 plus G-CSF in an outpatient setting. The rate of complete response was evaluated as the main outcome. Other outcomes were rate of complete control of CINV, incidence of nausea/vomiting of any grade and safety.RESULTSA total of 88 patients were enrolled. A complete response was achieved in 45.5 % of patients; among them, 39.77 % attained complete control of CINV. Nausea and vomiting never occurred in 34.1 % and 45.5 % of patients, respectively. No episodes of grade 3–4 nausea and/or vomiting were documented. GTDS was safe and well tolerated.CONCLUSIONIn real world, GTDS provided an innovative, effective, and well-tolerated control of CINV in MM patients after chemo-mobilization with CY. The study found out effectiveness of a non-invasive delivery system of antiemetic.  相似文献

ObjectiveTo investigate the feasibility of correcting coexistent penile torsion and chordee without hypospadias by mobilization of the urethra and spongiosum.Materials and MethodsA retrospective study of nine patients with simultaneous penile torsion and chordee without hypospadias was undertaken between January 2006 and December 2012. During this period, a total of 364 cases of hypospadias and 38 of chordee without hypospadias were operated on, making a total of 402 patients with hypospadias-related complexes. The same steps were used for correction of both torque and chordee. After a circumcoronal incision, the penis was fully degloved and the spongiosum with urethra was lifted up off the cavernosa. Next, mobilization of the hypoplastic urethra with spongiosum was extended into the glans. If chordee or torque persisted, urethral mobilization was performed proximally up to the bulbar urethra, as required. Spongioplasty and glansplasty were done and a per-urethral stent was kept in for three to five days.ResultsThe age of the patients ranged from 5 to 16 years (median 6 years). Penile torsion ranged from 30° to 120°, with a median of 75°. Ventral chordee ranged from 45° to 100°, with a median of 50°. A ratio of 1:9.6 was found for chordee without hypospadias compared to the total hypospadias cases, with an incidence of 9.5%. The ratio of chordee without hypospadias with torsion compared to the total hypospadias cases was 1:29. There was an incidence of chordee without hypospadias with penile torsion of 3.5% in all patients with hypospadias. The ratio of chordee without hypospadias with torsion to only chordee without hypospadias was 1:1.71, with an incidence of 37.0%. Every step contributed to the correction of curvature and torsion. Chordee was corrected in two patients by penile degloving and lifting of the spongiosa off the urethral plate; three patients required additional mobilization of the urethra into the glans. Another two patients needed proximal urethral mobilization and one required a dorsal plication. In five patients, torque was corrected by penile degloving, lifting of the spongiosa and mobilization of the urethra into the glans; four patients required further proximal urethral mobilization. All patients had excellent functional and cosmetic results. No residual chordee or torque was observed in any patient on follow-up at 12–24 months.ConclusionThe technique of distally mobilizing a hypoplastic urethra with spongiosum from the corpora into the glans, and proximally up to the bulbar region corrects moderate to severe chordee and torsion with excellent cosmetic results. The incidence of torsion with chordee without hypospadias was 3.5% of all cases of hypospadias.  相似文献

Incidental dural tears being a familiar complication in spine surgery could result in dreaded postoperative outcomes. Though the literature pertaining to their incidence and management is vast, it is limited by the retrospective study designs and smaller case series. Hence, we performed a prospective study in our institute to determine the incidence, surgical risk factors, complications and surgical outcomes in patients with unintended durotomy during spine surgery over a period of one year. The overall incidence in our study was 2.3% (44/1912). Revision spine surgeries in particular had a higher incidence of 16.6%. The average age of the study population was 51.6 years. The most common intraoperative surgical step associated with dural tear was removal of the lamina, and 50% of the injuries were during usage of kerrison rongeur. The most common location of the tear was paramedian location (20 patients) and the most common size of the tear was about 1 mm-5mm (31 patients). We observed that the dural repair techniques, placement of drain and prolonged post-operative bed rest didnot significantly affect the post-operative outcomes. One patient in our study developed persistent CSF leak, which was treated by subarachnoid lumbar drain placement. No patients developed pseudomeningocele or post-operative neurological worsening or re-exploration for dural repair. Wound complications were noted in 4 patients and treated by debridement and antibiotics. Based on our study, we have proposed a treatment algorithm for the management of dural tears in spine surgery.  相似文献

Tocopherol mobilization during intensive exercise   总被引:1,自引:0,他引:1  
Summary This work shows that the level of plasma tocopherol (vitamin E) which has free radical scavenging properties rises significantly during intensive exercise. It is proposed that mobilization of tocopherol could help to prevent lipoperoxidation phenomena occurring in exercising skeletal muscle. A hypothetical mechanism relating to a lipolysis effect is discussed to explain this mobilization.  相似文献
