RESUMO

INTRODUCTION: The treatment of patients with a cochlear implant (CI) is usually an elective, complex and interdisciplinary process. As an important source of information, patients often access the internet prior to treatment. The quality of internet-based information regarding thematic coverage has not yet been analysed in detail. Therefore, the aim of this study was to analyse the information on CI care available on the internet regarding its thematic coverage and readability. MATERIAL METHODS: Eight search phrases related to CI care were defined as part of the study. A checklist for completeness of thematic coverage was then created for each search phrase. The current German CI clinical practice guideline and the white paper on CI care in Germany were used as a basis. As a further parameter, readability was assessed using Flesch Reading Ease Scores. The search phrases were used for an internet search with Google. The first ten results were then analysed with regard to thematic coverage, readability and the provider of the website. RESULTS: A total of 80 websites were identified, which were set up by 54 different providers (16 providers were found in multiple entries) from eight different provider groups. The average completeness of thematic coverage was 41.6 ± 28.2%. Readability according to the Flesch Reading Ease Score was categorised as "hard to read" on average (34.7 ± 14.2 points, range: 0-72). There was a negative statistically significant correlation between the thematic coverage of content and readability (Spearman's rank correlation: r = - 0.413, p = 0.00014). The completeness of thematic coverage of information on CI care available on the internet was highly heterogeneous and had a significant negative correlation with the readability. This result should be taken into account by both the providers of internet information and by patients when using internet-based information on CI care and help to further improve the quality of web-based information.

RESUMO

Atopic dermatitis (AD) is a highly heterogeneous chronic inflammatory skin disorder that is frequently associated with a plethora of comorbidities. AD is, therefore, considered a systemic disease impacted by a considerable burden and leading to poor quality of life, especially in patients with moderate-to-severe disease. Since atopic and non-atopic comorbidities can further worsen the disease course, accurate establishment of the patient's individual intrinsic risk profile and needs is crucial and may help in guiding the selection of the best treatment option. Better quality of care for patients with AD can be delivered through a multidisciplinary team led by a dermatologist, for comprehensive patient management. The implementation of a multidisciplinary approach for AD could enhance the delivery of optimised and safe treatments, improve the standard of care and patient outcomes in the short and long term, and prevent or delay the lifelong impact of uncontrolled AD. Understanding the unmet needs, assessing correctly the patient risk profile and enhancing the shared patient-physician decision-making process can lead to disease control and quality-of-life improvement, especially in the context of the introduction of newer treatment for AD. This narrative review is a call for more data to establish standardised patient profiles and multidisciplinary strategies in AD management. In view on the fast-evolving treatments for AD, this review aims at highlighting the importance of a multidisciplinary approach to a comprehensive assessment and holistic care in patients with moderate-to-severe AD.

RESUMO

Although there are different data supporting benefits of HLA matching in kidney transplantation, its role in heart transplantation is still unclear. HLA mismatch (MM) between donor and recipient can lead to the development of donor-specific antibodies (DSA) which produces negative events on the outcome of heart transplantation. Moreover, DSAs are involved in the development of antibody-mediated rejection (AMR) and are associated with an increase in cardiac allograft vasculopathy (CAV). In this study it is analyzed retrospectively the influence of HLA matching and anti-HLA antibodies on overall survival, AMR and CAV in heart transplantation. For this retrospective study are recruited heart transplanted patients at the Cardiac Transplantation Centre of Naples between 2000 and 2019. Among the 155 heart transplant patients, the mean number of HLA-A, B, -DR MM (0 to 6) between donor and recipient was 4.5 ± 1.1. The results show a negative association between MM HLA-DR and survival (p = 0.01). Comparison of patients with 0-1 MM at each locus to all others with 2 MM, for both HLA class I and class II, has not showed significant differences in the development of CAV. Our analysis detected DSA in 38.1% of patients. The production of de novo DSA reveals that there is not an influence on survival (p = 0.72) and/or AMR (p = 0.39). Instead, there is an association between the production of DSA class II and the probability of CAV development (p = 0.03). Mean fluorescence intensity (MFI) values were significantly higher in CAV-positive patients that CAV-negative patients (p = 0.02). Prospective studies are needed to evaluate HLA class II matching as an additional parameter for heart allocation, especially considering the increment of waiting list time.

RESUMO

INTRODUCTION: Atopic dermatitis (AD) is a chronic inflammatory skin disease that negatively impacts the quality of life and work productivity of patients. OBJECTIVES: We sought to evaluate the real-world burden of AD patients in Italy. METHODS: This sub-analysis of the MEASURE-AD multicountry study conducted between December 2019-2020 included patients diagnosed with moderate-to-severe AD eligible for or receiving systemic therapy in the previous 6 months. During a single visit, physician and patient-reported questionnaires were used. RESULTS: A total of 118 adult patients were enrolled and 57.6% (N = 68) of patients had moderate-to-severe AD at the time of enrolment according to the Eczema Area and Severity Index. Sleep disorders interfered with daily function in the previous week in 58.5% (N = 69) of patients, pruritus was severe in 50% (N = 59) and 42.4% (N = 50) reported a flare lasting >7 days in the previous 6 months. According to the Dermatology Quality of Life Index, 37.3% (N = 44) of patients reported a severe impact of AD and approximately 10% had clinical depression/anxiety. Current drug therapy was considered inadequate in controlling AD in 26.3% (N=31) of patients. Work activity impairment was 38.6±31.7% and monthly AD-related expenses were 148.6±134.6 Euros per patient. CONCLUSIONS: This real-life study documents a high burden of disease in patients with moderate-severe AD in Italy.

RESUMO

BACKGROUND: In elderly patients with newly diagnosed multiple myeloma (MM), the addition of bortezomib to standard, combined oral melphalan and prednisone (MP) significantly increases the response rate and event-free survival compared with MP alone. METHODS: In this phase 1/2 trial, the authors assessed the dosing, efficacy, and safety of a lower dose-intensity MP schedule plus weekly bortezomib as salvage treatment for elderly patients with MM. To assess the maximum tolerated dose, 19 patients who had relapsed/refractory MM after 1 or 2 lines of treatment entered the first phase of the study. They received melphalan at a dose of 24 mg for 28 days; bortezomib 1.3 mg/m(2) on days 1, 8, 15, and 22; and prednisone at a dose of 50 mg every other day of a 28-day cycle for a total of 9 cycles. At the end of the first phase, based on the good efficacy and acceptable toxicity of this combination, an additional 23 patients were enrolled. RESULTS: After a median follow-up of 21 months, of 42 patients who relapsed, 24 (57%) obtained at least a partial response, 4 had stable disease, and 11 had progressive disease. The median time to progression was 18 months, and the median overall survival was 30 months. Grade 3 and 4 toxicity was observed in 16 of 42 patients (38%) and was more frequent during the early cycles. CONCLUSIONS: A weekly infusion of bortezomib associated with lower dose-intensity MP induced a high proportion of responses and was well tolerated in elderly patients with relapsed/refractory MM.

RESUMO

Monoclonal gammopathy of undetermined significance (MGUS) has been associated with an increased risk of thrombosis. We carried out a retrospective multicentre cohort study on 1491 patients with MGUS. In 49 patients (3.3%) MGUS was diagnosed after a thrombotic event. Follow-up details for a period of at least 12 months after diagnosis of MGUS were obtained in 1238 patients who had no recent history of thrombosis (<2 years) prior to diagnosis, for a total of 7334 years. During the follow-up, 33 of 1238 patients (2.7%) experienced thrombosis, with an incidence of 2.5 arterial events and 1.9 venous events per 1000 patient-years. Multivariate analysis showed increased risks of arterial thrombosis in patients with cardiovascular risk factors [hazard ratio (HR) 4.92, 95%confidence interval (CI) 1.42-17.04], and of venous thrombosis in patients with a serum monoclonal (M)-protein level >16 g/l at diagnosis (HR 3.08, 95%CI 1.01-9.36). No thrombosis was recorded in patients who developed multiple myeloma (n = 50) or other neoplastic diseases (n = 21). The incidence of arterial or venous thrombosis in patients with MGUS did not increase relative to that reported in the general population for similarly aged members. Finally, the risk of venous thrombosis did increase when the M-protein concentration exceeded >16 g/l.

RESUMO

BACKGROUND: Smoldering multiple myeloma (SMM) presents a high risk of progression to symptomatic MM (sy-MM). Herein, we analyzed some predictors of development of sy-MM. In 144 patients with SMM, we also compared the risk of progression predicted by bone marrow plasma cell (BMPC) involvement on the bone marrow biopsy (BMB) versus bone marrow aspirates (BMA). METHODS: From January 1980 to July 2010, 397 patients with SMM observed in 12 centers of the Multiple Myeloma GIMEMA (Gruppo Italiano Malattie EMatologiche dell'Adulto) Latium Working Group have been analyzed. At progression to sy-MM, the severity of clinical presentation was graded according to the need of intensive supportive care. RESULTS: After a median follow-up of 135 months, the cumulative incidence of progression rates to sy-MM were 45%, 55%, and 75% at 10, 15, and 20 years, respectively. Hemoglobin ≤12.5 g/dL, monoclonal component ≥2.5 g/dL, and BMPC ≥60% were the only parameters negatively affecting the cumulative incidence of progression. In particular, 10 of 397 (2.5%) patients with BMPC ≥60% had a 5.6-fold increased risk of fast progression (within 2 years), which occurred with severe clinical manifestations in 62% of cases. BMB was more sensitive for the detection of BMPC involvement, even though BMA was a more reliable indicator of a rapid progression to sy-MM. CONCLUSIONS: The highest risk of rapid evolution to sy-MM and the severity of clinical manifestation at the progression suggest that SMM patients with a BMPC ≥60% should be treated soon after diagnosis. Moreover, BMPC is a more reliable index for progression to sy-MM if assessed by BMA.

RESUMO

In a recent phase 3 trial, bortezomib-melphalan-prednisone-thalidomide followed by maintenance treatment with bortezomib-thalidomide demonstrated superior efficacy compared with bortezomib-melphalan-prednisone. To decrease neurologic toxicities, the protocol was amended and patients in both arms received once-weekly instead of the initial twice-weekly bortezomib infusions: 372 patients received once-weekly and 139 twice-weekly bortezomib. In this post-hoc analysis we assessed the impact of the schedule change on clinical outcomes and safety. Long-term outcomes appeared similar: 3-year progression-free survival rate was 50% in the once-weekly and 47% in the twice-weekly group (P > .999), and 3-year overall survival rate was 88% and 89%, respectively (P = .54). The complete response rate was 30% in the once-weekly and 35% in the twice-weekly group (P = .27). Nonhematologic grade 3/4 adverse events were reported in 35% of once-weekly patients and 51% of twice-weekly patients (P = .003). The incidence of grade 3/4 peripheral neuropathy was 8% in the once-weekly and 28% in the twice-weekly group (P < .001); 5% of patients in the once-weekly and 15% in the twice-weekly group discontinued therapy because of peripheral neuropathy (P < .001). This improvement in safety did not appear to affect efficacy. This study is registered at http://www.clinicaltrials.gov as NCT01063179.

RESUMO

High-dose (200 mg/m(2), MEL200) and intermediate-dose melphalan (100 mg/m(2), MEL100) showed significant activity in myeloma. In a phase 3 study, 298 patients were randomly assigned to receive 2 autologous transplantations after conditioning with MEL200 or MEL100. Ninety-six of 149 (64%) completed MEL200 and 103 of 149 (69%) MEL100. Best response to MEL200 was: complete remission 22 of 149 (15%); partial remission 95 of 149 (64%), for an overall response rate of 79%. Best response to MEL100 was: complete remission 12 of 149 (8%); partial remission 95 of 149 (64%), for an overall response rate of 72%. Overall survival did not differ (P = .13); median progression-free survival (31.4 vs 26.2 months, P = .01), median time to progression (34.4 vs 27.0 months, P = .014) were longer in the MEL200. Treatment-related mortality was 3.1% in the MEL200 and 2.9% in the MEL100 group. Severe neutropenia and infections were marginally superior, whereas severe thrombocytopenia, mucositis, gastrointestinal adverse events, and the overall occurrence of at least 1 nonhematologic grade 3 or 4 adverse event were significantly higher in the MEL200 cohort. We conclude that MEL200 leads to longer remission duration and should be considered the standard conditioning regimen for autologous transplantation. This study was registered at www.clinicaltrials.gov as #NCT00950768.

RESUMO

OBJECTIVE: In field hockey, injuries are assessed by various recording techniques leading to a heterogenic collection of poorly comparable injury data. METHODS: Injury data were prospectively collected at the 2016 Men's Hockey Junior World Cup using the match injury reports (MIRs), video injury clips provided by the Fédération Internationale de Hockey, and daily medical reports (DMRs). A pilot study comparing injury type, mechanism, location on the field, injured body part and overall injury incidence among the different injury recording techniques was performed. RESULTS: MIRs and video injury clips were completely available for analysis. DMRs were returned from 11 out of 16 teams (69%). In total, MIRs yielded 28, video analysis 36, and DMRs 56 injuries. Overall injury rate varied between 24.8 and 57.9 injuries per 1000 player match hours. The majority of injuries affected the lower limbs by all three methods (41.7-61.2%) and were mainly caused by having been hit by the ball (20.4-50%) or stick (11.1-28.6%). Reports of concussions during competition were incoherent between MIR (2 cases) and DMR (no cases). The DMR was the only method to record overuse injuries (16.1%), injuries in training (12.5%), and time-loss injuries of one or two days (12.5%) or of three or more days (14.3%). CONCLUSION: Injury data vary substantially between the MIR, DMR and injury video recording technique. Each recording technique revealed specific strengths and limitations. To further advance injury research in field hockey, the strengths of each recording technique should be brought together for a synergistic injury assessment model.

RESUMO

Philadelphia positive (Ph+) chronic myeloid leukaemia (CML) presenting synchronously or following non-Hodgkin lymphoma (NHL) has only rarely been reported. Herein, we refer on a case of Ph+ CML occurring after a breast cancer and a NHL with multiple relapses. After obtaining complete cytogenetic remission with imatinib, the patient presented a new NHL relapse, that was treated with rituximab concomitantly to imatinib. Therapy was well tolerated and the patient is presently alive in complete remission of either NHL and CML. We also reviewed the literature relating the uncommon association of these two unrelated diseases.

RESUMO

One of the major changes suggested by the World Health Organization (WHO) classification with respect to the French-American-British (FAB) proposal for myelodysplastic syndromes (MDS) was to lower the bone marrow (BM) blast count from 30 to 20%, thus eliminating the refractory anaemia with excess of blasts in transformation (RAEB-t) category. However, a general consensus has not been reached, and several authors still retain RAEB-t as an MDS sub-entity. We re-evaluated our series of 74 patients classified as RAEB-t according to the FAB criteria by stratifying them into two subsets: patients with at least 5% peripheral blast (PB) cells but with BM blasts <20% (group I) and patients with BM blastosis between 20 and 30% and PBs <5% (group II). We found differences among the two groups regarding sex, haematological parameters at presentation (white blood cell and neutrophil counts, haemoglobin level) and frequency of infectious episodes during the course of disease. We did not find differences as to the frequency of acute myeloid leukaemia transformation, but a significant difference was evidenced as to survival (9.3 vs. 16 months in group I vs. group II, respectively; p = 0.02). Furthermore, at our institution, we compared the RAEB-t group I patients who, based on >5% PBs, should be included in the RAEB-II category according to the WHO criteria, with a group of 98 patients who were diagnosed as RAEB-II according to the WHO criteria. The findings showed that the aggregation of these two subsets appeared inappropriate, because patients of the two groups showed different clinical features and rates of acute transformation. In conclusion, the RAEB-t entity according to the FAB criteria, although including heterogeneous clinical patient subsets, should more likely be considered as an advanced stage of MDS, rather than a true acute myeloid leukaemia.

RESUMO

The differential diagnosis between multiple myeloma (MM) and Waldenström's macroglobulinemia (WM) is generally well defined. Consistent with a diagnosis of MM is the presence of a non-IgM monoclonal gammopathy associated to multiple osteolytic lesions and plasma cell infiltration of the bone marrow. Characteristic of WM is the presence of an IgM monoclonal gammopathy associated to lymphoadenopathy, hepatosplenomegaly, anemia and hyperviscosity syndrome in the presence of a monoclonal lymphoplasmacytoid proliferation in the bone marrow. Nonetheless, few cases of IgM myeloma have been reported that display clinico-pathologic features intermediate between MM and WM. Here, this study describes four of 317 (1.2%) patients with an IgM monoclonal gammopathy in whom the morphologic and clinical features were consistent with a diagnosis of IgM myeloma.

RESUMO

Liver plasmacytoma is a very rare form of solitary plasmacytoma, in fact the presence of plasma cells in the liver is generally associated with a more aggressive form of multiple myeloma. We report an unusual case of liver plasmacytoma without systemic disease, diagnosed by percutaneous needle biopsy of the hepatic lesion, treated with six courses of melphalan and prednisone who achieved a good clinical remission after five years of follow-up.

RESUMO

Susceptibility to apoptosis varies in different forms of myelodysplastic syndromes (MDS). Our in vitro study aimed at better defining the cell kinetic profile by investigating whether G-CSF and interferon-alpha (IFNalpha) were capable of controling apoptotic/proliferative mechanisms in RAEB as well as in RAEB-t forms. Apoptosis and cell-cycle distribution were measured in mononuclear and in CD34+ cells from bone marrow samples of 27 MDS patients with RAEB (n = 15) and RAEB-t (n = 12). In selected samples, the in vitro influence of G-CSF and lymphoblastoid (Ly)-IFNalpha on the apoptotic susceptibility and on the cell kinetics of the above MDS populations was evaluated. RAEB samples showed a significantly greater apoptosis than RAEB-t ones, both in mononuclear cells (14.76%+/-8.73 vs. 5.95%+/-3.88, P= 0.0058) and in CD34+ cells (24.66%+/-16.08 vs. 3.96%+/-2.57, P = 0.0007). Short-term cell culture in the presence of G-CSF reduced apoptosis in CD34+ cells in all 4 RAEB samples tested (39.1%+/-40.7 vs. 21.0%+/-23.5, P = n.s.); the percentage of cells in S-phase significantly increased in 3/4 samples (19.90%+/-4.40 vs. 32.40%+/-7.85, P = 0.03). Ly-IFNalpha protected CD34+ cells from apoptosis in 3/4 RAEB samples (25.7%+/-8.06 vs. 10.9%+/-8.8, P = n.s.), but did not modulate cell-cycle distribution. G-CSF and Ly-IFNalpha failed to affect apoptosis and proliferation in RAEB-t. These observations indicate that in RAEB forms increased apoptosis can be efficiently counteracted in most of the samples by both G-CSF and Ly-IFNalpha, suggesting that only in these forms a retained regulatory mechanism on the apoptotic/ proliferative balance may allow therapeutic intervention with apoptotic regulators.

RESUMO

PURPOSE: The present study was undertaken to determine the feasibility of using primary stability as a predictor of implant success in patients whose implants were immediately loaded. MATERIALS AND METHODS: The study included 40 patients, in whom a total of 190 implants were placed, 102 in maxillary sites and 88 in mandibular sites. All were loaded within 72 hours of placement. Sixteen patients were completely edentulous in the mandible and/or the maxilla. The remaining 24, who were partially edentulous, received fixed partial dentures or single-implant restorations. All of the definitive implant restorations were screw retained. The criterion for loading was clinical judgment of primary stability, verified by a "screw test." Impressions were made after implant placement to facilitate the fabrication of a laboratory-made heat-processed provisional restoration from acrylic resin. Following a 4-month period for osseointegration and soft tissue healing, definitive fixed prostheses were fabricated. RESULTS: There were no surgical complications. After 1 to 2 years, all 190 implants had survived and were considered 100% successful, as determined by independent testing of mobility and radiographic evidence of osseointegration. In 4 patients, fracture of the provisional restoration occurred during the healing period. DISCUSSION: Clinical research has shown that immediate loading is a viable treatment modality. The favorable success rate reported in this study for rough-surfaced implants suggests that adherence to a protocol, an important parameter of which is primary stability above 32 Ncm, can lead to osseointegration. CONCLUSION: The results of this limited investigation suggest that patients who are partially or completely edentulous may be immediately restored with implants and fixed provisional restorations, provided that the dental implants are adequately stable immediately after their surgical placement. This alternative therapeutic approach did not appear to affect the up-to-2-year survival of the implants in this patient population.

RESUMO

PURPOSE: Dental implants are accepted as a successful alternative to conventional fixed and removable prostheses for the treatment of partial or complete edentulism. However, there have been few studies of the success of implants from the patients' perspective. The purpose of this study was to assess patient overall satisfaction with the outcome of treatment with maxillary anterior implants. MATERIALS AND METHODS: A self-administered mailed questionnaire, which was developed for this project, and a data abstraction form, which was designed based on information available from the corresponding dental records of 123 eligible subjects, were utilized to survey implant patients. RESULTS: Seventy-eight of 123 eligible subjects responded to the mailed, self-administered, structured questionnaire. Twelve of the 24 questionnaire variables demonstrated statistically significant bivariate associations with the dependent variable "overall patient satisfaction." Five variables--implant position, definitive restoration shape, appearance, effect on speech, and chewing capacity--were strongly associated with overall satisfaction. No demographic or treatment-related, dental record-abstracted variable, of the 25 that were examined, was statistically significant. DISCUSSION: The practitioner who provides implant restorations should be aware of the multidimensional aspects of patient satisfaction with implant treatment. This study suggests that patient satisfaction with key elements influences the overall acceptance of maxillary anterior implant prostheses, which are esthetically critical. Communication between dentist and patient is important to achieve optimal results that will be satisfactory to both. Discussion of treatment limitations may also help patients to develop realistic expectations of the final result. CONCLUSIONS: In this limited investigation, patient satisfaction with implant position, restoration shape, overall appearance, effect on speech, and chewing capacity were critical for patient overall acceptance of the dental implant treatment.

RESUMO

PURPOSE: Bortezomib-melphalan-prednisone (VMP) has improved overall survival in multiple myeloma. This randomized trial compared VMP plus thalidomide (VMPT) induction followed by bortezomib-thalidomide maintenance (VMPT-VT) with VMP in patients with newly diagnosed multiple myeloma. PATIENTS AND METHODS: We randomly assigned 511 patients who were not eligible for transplantation to receive VMPT-VT (nine 5-week cycles of VMPT followed by 2 years of VT maintenance) or VMP (nine 5-week cycles without maintenance). RESULTS: In the initial analysis with a median follow-up of 23 months, VMPT-VT improved complete response rate from 24% to 38% and 3-year progression-free-survival (PFS) from 41% to 56% compared with VMP. In this analysis, median follow-up was 54 months. The median PFS was significantly longer with VMPT-VT (35.3 months) than with VMP (24.8 months; hazard ratio [HR], 0.58; P < .001). The time to next therapy was 46.6 months in the VMPT-VT group and 27.8 months in the VMP group (HR, 0.52; P < .001). The 5-year overall survival (OS) was greater with VMPT-VT (61%) than with VMP (51%; HR, 0.70; P = .01). Survival from relapse was identical in both groups (HR, 0.92; P = .63). In the VMPT-VT group, the most frequent grade 3 to 4 adverse events included neutropenia (38%), thrombocytopenia (22%), peripheral neuropathy (11%), and cardiologic events (11%). All of these, except for thrombocytopenia, were significantly more frequent in the VMPT-VT patients. CONCLUSION: Bortezomib and thalidomide significantly improved OS in multiple myeloma patients not eligible for transplantation.
