Shared motherhood IVF: high delivery rates in a large study of treatments for lesbian couples using partner-donated eggs.

Shared motherhood IVF treatment is becoming increasingly accepted among assisted reproductive techique practitioners and patients in Europe, although data on its overall efficiency remain scarce. This 6-year retrospective study from a single, private, UK HFEA-regulated centre included consecutive lesbian couples (n = 121) undergoing shared motherhood IVF treatment (141 cycles). Recipients were more parous and had undergone more previous intrauterine insemination and IVF treatments than donor partners, who had slightly higher ovarian reserve markers than recipients. Indications in most cycles (60%) were non-medical. Most (79%) egg-providers were stimulated with gonadotrophin releasing hormone antagonist protocol, and no moderate or severe cases of ovarian hyperstimulation syndrome (OHSS) arose. A total of 172 fresh and vitrified-warmed embryo transfers were carried out: 70% at the blastocyst-stage and 58% involved a single embryo. Cumulative live birth rate per receiver was 60% (72/120), and twin delivery rate was 14% (10/72). Perinatal outcome parameters were better for singleton than twin pregnancies, although the latter also achieved generally favourable outcomes. No significant difference in cumulative outcomes were found between synchronized and non-synchronized cycles. Shared motherhood IVF combines ovarian stimulation with single blastocyst transfer to provide a safe and effective treatment modality offering reassuring obstetrical and perinatal outcomes.

Investigation of the sample preparation and curing treatment effects on mechanical properties and bioactivity of silica rich metakaolin geopolymer.

In many biomedical applications both the biological and mechanical behaviours of implants are of relevant interest; in the orthopaedic field, for example, favourable bioactivity and biocompatibility capabilities are necessary, but at the same time the mechanical characteristics of the implants must be such as to allow one to support the body weight. In the present work, the authors have examined the application of geopolymers with composition H24AlK7Si31O79 and ratio Si/Al=31 to be used in biomedical field, considering two different preparation methods: one of the activators (KOH) has been added as pellets in the potassium silicate solution, in the other as a water solution with 8M concentration. Moreover, a different water content was used and only some of the synthesized samples were heat treated. The chemical and microstructural characterizations of those materials have been carried out by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Subsequently, the effects of the adopted preparation on the mechanical and biological properties have been studied: compressive strength tests have demonstrated that more fragile specimens were obtained when KOH was added as a solution. The bioactivity was successfully evaluated with the soaking of the samples in a simulated body fluid (SBF) for 3 weeks. The formation of a layer of hydroxyapatite on the surface of the materials has been shown both by SEM micrographs and EDS analyses.

Induction therapy with alemtuzumab (campath) in combined liver-kidney transplantation: University of Bologna experience.

BACKGROUND: Combined liver-kidney transplantation (LKT) is considered to be a safe procedure, but the appropriate immunosuppressive regimen is unclear. PATIENTS AND METHODS: Between January 1997 and October 2011, 55 patients were listed for LKT: 45 (82%) were effectively transplanted, 5 (9.2%) died whereon here the waiting list, 3 (5.5%) temporarily out of waiting list, 1 (1.8%) was on waiting list and 1 (1.8%) refused LKT. Five LKTs treated with cyclosporine (CyA) were excluded from the analysis. Mean recipient age was 50.32 ± 10.32 years (14-65), MELD score at time of LKT was 19.22 ± 4.69 (8-29), mean waiting list time was 8.14 ± 9.50 months (0.1-35.76), and follow-up, 4.09 ± 3.02 years (0.01-10.41). Main indications for LKT were policystic disease (n = 15; 37%), hepatitis virus C (HCV)-related cirrhosis (n = 9; 22%) metabolic disease (n = 5; 13%), hepatitis virus B (HBV) cirrhosis (n = 4; 10%), alcoholic cirrhosis (n = 4; 10%), and cholestatic disease (n = 3; 8%). Immunosuppressive regimen was based on tacrolimus and steroids in 40 cases with induction therapy with alemtuzumab (Campath; 0.3 mg/kg) in 13 of 40 instances cases administered on day 0 and day 7. RESULTS: Postoperative mortality was 2.5%. Acute cellular rejection episodes were biopsy-proven in 2 (5%) cases, post-LKT infections developed in 17 cases (42.5%), and de novo cancer developed in 3 (7.5%) cases. Similar 5-year overall survivals were obtained irrespective of the LKT indication: 100% in cholestatic and alcoholic cirrhosis patients, 86% in policystic disease, 75% in metabolic disease and HBV patients, and 66% in HCV cirrhosis. Overall survivals for the alemtuzumab vs without-induction therapy groups at 1, 3, and 5-years were 100%, 85.7%, and 85.7% vs 76%, 76%, and 70%, respectively (P = .04). CONCLUSION: An immunosuppressive regimen based on tacrolimus and steroids with induction therapy with alemtuzumab was safe, with excellent long-term results for combined LKT.

Prognostic significance of disordered calcium metabolism in hormone-refractory prostate cancer patients with metastatic bone disease.

Bone metabolic disruption that occurs in bone metastatic prostate cancer could lead to disturbances of calcium metabolism. The prognostic role of either hypocalcemia or hypercalcemia was assessed in a consecutive series of hormone-refractory bone metastatic prostate cancer patients. Serum calcium was measured in 192 patients. The presence of hypocalcemia and hypercalcemia was related with baseline biochemical and clinical characteristics and the role of these two calcium disturbances in predicting prognosis and adverse skeletal-related events (SREs) was assessed. As compared to normocalcemic patients, hypocalcemic patients (n=51) had higher tumor load in bone (P=0.005), higher plasma chromogranin A (CgA, P=0.01), serum alkaline phosphatase (P=0.01), urinary N-telopeptide (NTX, P=0.002) and lower hemoglobin values (P=0.01), while hypercalcemic patients (n=16) had higher plasma CgA (P=0.001) and serum lactate dehydrogenase values (P=0.001), higher bone pain (P=0.003) and a lower frequency of pure osteoblastic lesions (P=0.001). Hypercalcemia was significantly associated with poor prognosis: hazard ratio (HR), 1.9 (95% confidence Interval (CI) 1.2-3.3) and higher risk to develop SREs HR, 2.5 (95% CI 1.2-5.2, P=0.01), while hypocalcemia was not associated with poor prognosis. The prognostic role of hypercalcemia was maintained in multivariate analysis after adjusting for validated prognostic parameters: HR, 2.72 (95% CI 1.1-6.8, P=0.03). These data suggest that serum calcium levels should be taken into account in the clinical decision-making process of bone metastatic prostate cancer patients. Patients with asymptomatic hypercalcemia could benefit of a strict follow-up and an immediate bisphosphonate treatment. Further prospective clinical trials are needed to confirm this finding.

Predictive factors for skeletal complications in hormone-refractory prostate cancer patients with metastatic bone disease.

Factors predictive of skeletal-related events (SREs) in bone metastatic prostate cancer patients with hormone-refractory disease were investigated. We evaluated the frequency of SREs in 200 hormone-refractory patients consecutively observed at our Institution and followed until death or the last follow-up. Baseline parameters were evaluated in univariate and multivariate analysis as potential predictive factors of SREs. Skeletal-related events were observed in 86 patients (43.0%), 10 of which (5.0%) occurred before the onset of hormone-refractory disease. In univariate analysis, patient performance status (P=0.002), disease extent (DE) in bone (P=0.0001), bone pain (P=0.0001), serum alkaline phosphatase (P=0.0001) and urinary N-telopeptide of type one collagen (P=0.0001) directly correlated with a greater risk to develop SREs, whereas Gleason score at diagnosis, serum PSA, Hb, serum albumin, serum calcium, types of bone lesions and duration of androgen deprivation therapy did not. Both DE in bone (hazard ratio (HR): 1.16, 95% confidence interval (CI): 1.07-1.25, P=0.000) and pain score (HR: 1.13, 95% CI: 1.06-1.20, P=0.000) were independent variables predicting for the onset of SREs in multivariate analysis. In patients with heavy tumour load in bone and great bone pain, the percentage of SREs was almost twice as high as (26 vs 52%, P<0.02) and occurred significantly earlier (P=0.000) than SREs in patients with limited DE in bone and low pain. Bone pain and DE in bone independently predict the occurrence of SREs in bone metastatic prostate cancer patients with hormone-refractory disease. These findings could help physicians in tailoring the skeletal follow-up most appropriate to individual patients and may prove useful for stratifying patients enrolled in bisphosphonate clinical trials.

Synovitis of small joints: sonographic guided diagnostic and therapeutic approach.

OBJECTIVE: The aim of this pictorial essay is to describe the sonographic guided approach to investigation and local injection therapy of a small joint in a patient with psoriatic arthritis (PA). METHODS: Sonographic pictures are obtained using a high frequency ultrasonography apparatus equipped with a 13-MHz transducer. RESULTS: Ultrasonography allows a careful morphostructural assessment of soft tissue involvement in PA patients. Sonographic findings include joint cavity widening, capsular thickening, synovial proliferation, synovial fluid changes, tendon sheath widening. Ultrasound guided placement of the needle within the joint and injection of corticosteroid under sonographic control can be easily performed. CONCLUSIONS: High frequency ultrasonography is a quick and safe procedure that allows a useful diagnostic and therapeutic approach in patients with arthritis of small joints.

Sonographic imaging of normal and osteoarthritic cartilage.

OBJECTIVES: This study was undertaken to describe representative sonographic features of normal and osteoarthritic cartilage. METHODS: Sonographic evaluation was performed with real-time ultrasound equipment, using 7.5-, 10-, 13-, 15-, and 20-MHz transducers. Normal and osteoarthritic cartilage has been studied in healthy subjects and in patients with osteoarthritis. RESULTS: Ultrasonography allows a safe, quick, and careful evaluation of both normal and osteoarthritic cartilage. A spectrum of images ranging from loss of cartilage transparency to marked narrowing of the cartilage layer can be depicted clearly in patients with osteoarthritis. Loss of clarity of the cartilaginous band and loss of the normal sharpness of the synovial space-cartilage interface are the earlier features of cartilage damage. CONCLUSIONS: Although the value of ultrasonography in the evaluation of articular cartilage remains to be determined, this imaging method can be regarded as a useful bedside procedure for initial diagnostic screening of osteoarthritic femoral condylar cartilage.

Prospective evaluation of high-dose ifosfamide-related nephrotoxicity in young adult patients with recurrent osteosarcoma previously treated with cisplatin, methotrexate and standard-dose ifosfamide.

A prospective evaluation of high-dose ifosfamide (IFO)-related nephrotoxicity in adults and young adults previously treated with cisplatin, methotrexate (MTX) and standard-dose IFO was performed. Eighteen patients (median age 22) with recurrent osteosarcoma were studied: 11 were pretreated with MTX, cisplatin and standard-dose IFO, and seven with MTX and cisplatin. The treatment was comprised of four cycles of high-dose IFO (15 g/m2 over 5 days CI) and mesna at equivalent dose with granulocyte colony stimulating factor support. Renal function was assessed before treatment, after each IFO cycle and after chemotherapy completion. Acute nephrotubular damage was always observed after each IFO cycle with significant changes of renal tubular enzymes N-acetyl-beta-D-glucosaminidase, alanine aminipeptidase, urinary excretion and reduction of tubular reabsorption of phosphate. The appearance of glycosuria was related to the cumulative dose received. Transient and reversible renal tubular acidosis was observed in three patients. WHO grade I renal toxicity was observed in two patients. After chemotherapy completion, persistent mild glomerular and nephrotubular impairment was observed in one patient who had also received aminoglycoside antibiotics due to febrile neutropenia. Persistent and mild glycosuria was documented in another patient. No significant changes compared to baseline values were observed in the remaining patients. We conclude that a chemotherapy regimen with high-dose IFO in young adults pretreated with MTX, cisplatin and standard-dose IFO is feasible with a mild, usually reversible, nephrotoxicity.

The clinical features of rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by progressive damage of synovial-lined joints and variable extra-articular manifestations. Tendon and bursal involvement are frequent and often clinically dominant in early disease. RA can affect any joint, but it is usually found in metacarpophalangeal, proximal interphalangeal and metatarsophalangeal joints, as well as in the wrists and knee. Articular and periarticular manifestations include joint swelling and tenderness to palpation, with morning stiffness and severe motion impairment in the involved joints. The clinical presentation of RA varies, but an insidious onset of pain with symmetric swelling of small joints is the most frequent finding. RA onset is acute or subacute in about 25% of patients, but its patterns of presentation also include palindromic onset, monoarticular presentation (both slow and acute forms), extra-articular synovitis (tenosynovitis, bursitis), polymyalgic-like onset, and general symptoms (malaise, fatigue, weight loss, fever). The palindromic onset is characterized by recurrent episodes of oligoarthritis with no residual radiologic damage, while the polymyalgic-like onset may be clinically indistinguishable from polymyalgia rheumatica in elderly subjects. RA is characteristically a symmetric erosive disease. Although any joint, including the cricoarytenoid joint, can be affected, the distal interphalangeal, the sacroiliac, and the lumbar spine joints are rarely involved. The clinical features of synovitis are particularly apparent in the morning. Morning stiffness in and around the joints, lasting at least 1 h before maximal improvement is a typical sign of RA. It is a subjective sign and the patient needs to be carefully informed as to the difference between pain and stiffness. Morning stiffness duration is related to disease activity. Hand involvement is the typical early manifestation of rheumatoid arthritis. Synovitis involving the metacarpophalangeal, proximal interphalangeal and wrist joints causes a characteristic tender swelling on palpation with early severe motion impairment and no radiologic evidence of bone damage. Fatigue, feveret, weight loss, and malaise are frequent clinical signs which can be associated with variable manifestations of extra-articular involvement such as rheumatoid nodules, vasculitis, hematologic abnormalities, Felty's syndrome, and visceral involvement. Although there is no laboratory test to exclude or prove the diagnosis of rheumatoid arthritis, several laboratory abnormalities can be detected. Abnormal values of the tests for evaluation of systemic inflammation are the most typical humoral features of RA. These include: erythrocyte sedimentation rate, acute phase proteins and plasma viscosity. Erythrocyte sedimentation rate and C-reactive protein provide the best information about the acute phase response. The C-reactive protein is strictly correlated with clinical assessment and radiographic changes. Plain film radiography is the standard investigation to assess the extent of anatomic changes in rheumatoid arthritis patients. The radiographic features of the hand joints in early disease are characterized by soft tissue swelling and mild juxtaarticular osteoporosis. In the the past 10 years, ultrasonography has gained acceptance for studying joint, tendon and bursal involvement in RA. It may improve the early clinical assessment and the follow-up of these patients, showing such details as synovial thickening even within finger joints. Other imaging techniques, such as magnetic resonance, computed tomography and scintigraphy may provide useful information about both the features and the extent for anatomic damage in selected rheumatoid arthritis patients. The natural history of the disease is poorly defined; its clinical course is fluctuating and the prognosis unpredictable. RA is an epidemiologically relevant cause of disability. An adequate early treatment of RA may alter the diseas

Methotrexate-induced pneumonitis in patients with rheumatoid arthritis and psoriatic arthritis: report of five cases and review of the literature.

Pneumonitis is emerging as one of the most unpredictable and potentially serious, adverse effects of treatment with MTX. Its prevalence in rheumatoid arthritis (RA) has been estimated from several retrospective and prospective studies to range from 0.3% to 18%. On the other hand, MTX-induced pneumonitis seems to be very rare in psoriatic arthritis (PsA). Our review of 194 RA patients and 38 PsA patients receiving MTX has identified four RA patients and one PsA patient with MTX-induced pneumonitis, giving a prevalence of 2.1% and 0.03%, respectively. Diagnosis was suggested by clinical history and radiographic findings, but the bronchoalveolar lavage plays an important role both in excluding infectious agents and in providing information for understanding the pathogenesis of lung injury. The presence of a lymphocyte alveolitis with a predominance of CD4+ T cells in 3 RA patients and CD8+ T cells with a concomitant increase in neutrophils in another case suggests that immunologically mediated reactions may be one damage mechanism in MTX-induced pneumonitis. Although risk factors for MTX-induced pulmonary toxicity are poorly understood, the presence in 3 out of 5 of our patients of pre-existing lung disease, represented by diffuse interstitial changes on chest X-ray, and mild bronchial asthma in two RA patients and by pulmonary silicosis in the patient with PsA may account for a predisposition to the development of MTX pneumonitis.

[Quantitative analysis of radiologic progression in rheumatoid arthritis: controversies and perspectives]. / L'analisi quantitativa della progressione radiologica nell'artrite reumatoide: controversie e prospettive.

Rheumatoid arthritis (RA) is a chronic inflammatory disease with symmetrical polyarthritis as the major feature. Persistent inflammation leads to largely irreversible joint damage which can be seen radiographically. Radiographs depict the progression of joint damage and alterations, which are one of the major parameters of RA evolution. Delayed radiologic progression is a good indicator of the success/failure of long-term drug treatment, but the quantitative analysis of changes over time and the reliability of scoring systems remain difficult steps. This paper focuses of the main current scoring systems, with an emphasis on the following four: Larsen method and its modification by Kayle, Sharp method and its modification by van der Heijde. The scoring method--be it grading, counting, or weighted counting--did not appear to influence reliability or repeatability, while the radiologist's training and the film reading technique were critical to identify disease progression accurately. Our data consistently suggest the paired reading method as the most suitable for radiologic progression assessment in RA. The radiologic studies of 62 patients with early RA after 7 years' follow-up showed joint damage in 82% of patients. The average annual progression rate of the total radiologic score obtained with Sharp method, summing erosions and joint space abnormalities, was faster in the earlier years of the disease (8.8 units/year) than later on (4.9 units/year) (p < 0.01). From the trialist's point of view, these results imply that disease duration is a critical feature for RA treatment outcome.

[Sulfasalazine: side effects and duration of therapy in patients with rheumatoid arthritis]. / La sulfasalazina: effetti collaterali e durata della terapia in pazienti affetti da artrite reumatoide.

Sulphasalazine (SSZ) is now recognised to be a useful agent in the management of rheumatoid arthritis (RA). We studied SSZ toxicity (2 g/die) and duration of therapy in 102 patients with RA. Adverse events occurred in 25.4% of all patients. In all patients the reactions subsided on either discontinuation of the drug or decrease of the dose. Gastrointestinal was the most common. At 5 years of follow-up the percentage of patients treated with SSZ still on drug was 29%, the inefficacy was 40% of the total drop-out.

Flow cytometry evaluation of urinary sediment in renal transplantation.

The value of exfoliative urinary cytology for the diagnosis of different pathological conditions in renal transplantation is widely recognized. The method, however, has not yet gained full acceptance, mainly because identification of the different cells is not always possible by means of standard staining techniques. In view of its characteristics, flow cytometry (FC) seems to represent a consistently reliable, rapid and innovative approach for differentialing the various cells present in the urinary sediment and assessing their number. This study gives the examination result of 223 urinary specimens from 127 transplanted patients selected according to pathology. Sediment cells, collected from fresh urine samples, were washed, treated with a lysing solution, resuspended in saline solution and directly analysed in a FACSCAN cytometer. Morphological evaluation showed: a small number of cells in patients with stable renal function; a larger number of cells, with predominance of lymphocytes, during acute rejection episodes; an absolute predominance of neutrophils during bacterial infection; large-sized cellular debris in cases of post-transplant tubular necrosis; and small cell debris in cases of cyclosporine cytotoxicity. Lymphocyte surface-marker evaluation made it possible to differentiate lymphocyte populations observed during acute rejection episodes (cytotoxic T-cell, CD8 and HLA class II and NK cells) from those detected during bacterial infection (T-cell CD4 positive). These results suggest that urinary FC may be a reliable diagnostic tool in clinical renal transplantation.
