Gynecomastia in epileptics treated with phenobarbital, phenytoin and fluoresone: Two case reports

Gynecomastia developed in two epileptic patients some months after the addition of oral fluoresone 750 mg daily to the phenobarbital and phenytoin already being administered. The common systemic diseases that may give rise to gynecomastia were excluded. One of the patients presented hyperprolactinemia and a raised estrogen/androgen ratio but the hormone levels were not raised in the other. The onset of symptoms after fluoresone in both cases is highly suggestive, although the pathogenetic mechanism is not clear.

Sommario Una ginecomastia insorta in due epilettici viene riportata. Il quadro si è sviluppato alcuni mesi dopo che ad un precedente trattamento con PB e PHT si era aggiunto fluoresone alla dose di 750 mg/die per os. Le comuni malattie sistemiche che possono determinare una ginecomastia sono state escluse. I rilievi ormonali hanno evidenziato soltanto in un caso un'iperprolattinemia ed un aumento del rapporto estrogeni-androgeni circolanti. La relazione temporale fra somministrazione del fluoresone e comparsa del quadro appare cruciate, tuttavia il meccanismo patogenetico resta da chiarire.

     

Knee arthrodesis with a press-fit modular intramedullary nail without bone-on-bone fusion after an infected revision TKA

IntroductionKnee arthrodesis can be an effective treatment after an infected revision Total Knee Arthroplasty (TKA). The main hypothesis of this study is that a two-stage arthrodesis of the knee using a press-fit, modular intramedullary nail and antibiotic loaded cement, to fill the residual gap between the bone surfaces, prevents an excessive limb shortening, providing satisfactory clinical and functional results even without direct bone-on-bone fusion.Material and methodsThe study included 22 patients who underwent knee arthrodesis between 2004 and 2009 because of recurrent infection following revision-TKA (R-TKA). Clinical and functional evaluations were performed using the Visual Analogue Scale (VAS) and the Lequesne Algofunctional Score. A postoperative clinical and radiographical evaluation of the residual limb-length discrepancy was conducted by three independent observers.ResultsVAS and LAS results showed a significant improvement with respect to the preoperative condition. The mean leg length discrepancy was less than 1 cm. There were three recurrent infections that needed further surgical treatment.DiscussionThis study demonstrated that reinfection after Revision of total knee Arthroplasty can be effectively treated with arthrodesis using a modular intramedullary nail, along with an antibiotic loaded cement spacer and that satisfactory results can be obtained without direct bone-on-bone fusion.     

Biweekly rituximab, cyclophosphamide, vincristine, non-pegylated liposome-encapsulated doxorubicin and prednisone (R-COMP-14) in elderly patients with poor-risk diffuse large B-cell lymphoma and moderate to high 'life threat' impact cardiopathy

This Phase II study assessed feasibility and efficacy of a biweekly R-COMP-14 regimen (rituximab, cyclophosphamide, non-pegylated liposome-encapsulated doxorubicin, vincristine and prednisone) in untreated elderly patients with poor-risk diffuse large B-cell lymphoma (DLBCL) and moderate to high 'life threat' impact NIA/NCI cardiac comorbidity. A total of 208 courses were delivered, with close cardiac monitoring, to 41 patients (median age: 73years, range: 62-82; 37% >75years) at a median interval of 15·6 (range, 13-29) days; 67% completed all six scheduled courses. Response rate was 73%, with 68% complete responses (CR); 4-year disease-free survival (DFS) and time to treatment failure (TTF) were 72% and 49%, respectively. Failures were due to early death (n=3), therapy discontinuations (no-response n=2; toxicity n=6), relapse (n=6) and death in CR (n=3). Incidence of cardiac grade 3-5 adverse events was 7/41 (17%; 95% confidence interval: 8-31%). Time to progression and overall survival at 4-years were 77% and 67%, respectively. The Age-adjusted Charlson Comorbidity Index (aaCCI) correlated with failures (P=0·007) with patients scoring ≤7 having a longer TTF (66% vs. 29%; P=0·009). R-COMP-14 is feasible and ensures a substantial DFS to poor-risk DLBCL patients who would have been denied anthracycline-based treatment due to cardiac morbidity. The aaCCI predicted both treatment discontinuation rate and TTF.     

Single-bundle patellar tendon versus non-anatomical double-bundle hamstrings ACL reconstruction: a prospective randomized study at 8-year minimum follow-up

Purpose  

The purpose of this study was to compare subjective, objective and radiographic outcome of the lateralized single-bundle bone-patellar tendon-bone autograft with a non-anatomical double-bundle hamstring tendons autograft anterior cruciate ligament (ACL) reconstruction technique at long-term follow-up.     

Changes in the orientation of knee functional flexion axis during passive flexion and extension movements in navigated total knee arthroplasty

Purpose

Recently, the functional flexion axis has been considered to provide a proper rotational alignment of the femoral component in total knee arthroplasty. Several factors could influence the identification of the functional flexion axis. The purpose of this study was to analyse the estimation of the functional flexion axis by separately focusing on passive flexion and extension movements and specifically assessing its orientation compared to the transepicondylar axis, in both the axial plane and the frontal plane.

Methods

Anatomical and kinematic acquisitions were performed using a commercial navigation system on 79 patients undergoing total knee arthroplasty with cruciate substituting prosthesis design. The functional flexion axis was estimated from passive movements, between 0° and 120° of flexion and back. Intra-observer agreement and reliability, internal–external rotation and the angle with the surgical transepicondylar axis, in axial and frontal planes, were separately analysed for flexion and extension, in pre- and post-implant conditions.

Results

The analysis of reliability and agreement showed good results. The identification of the functional flexion axis showed statistically significant differences both in relation to flexion and extension and to pre- and post-implant conditions, both in frontal plane and in axial plane. The analysis of internal–external rotation confirmed these differences in kinematics (p < 0.05, between 25° and 35° of flexion).

Conclusions

The identification of the functional flexion axis changed in relation to passive flexion and extension movements, above all in frontal plane, while it resulted more stable and reliable in axial plane. These findings supported the possible clinical application of the functional flexion axis in the surgical practice by implementing navigated procedures. However, further analyses are required to better understand the factors affecting the identification of the functional flexion axis.
