Autologous fat grafting efficacy in treating PostMastectomy pain syndrome: A prospective multicenter trial of two Senonetwork Italia breast centers.

Postmastectomy pain syndrome (PMPS) represents a common complication following breast surgery defined as a chronic neuropathic pain located in the front of the chest, in the axilla and in the upper arm that for more than 3 months after surgery. Several medications prove to be ineffective while autologous fat grafting revealed to be an innovative solution in the treatment of neuropathic pain syndromes based on retrospective studies. For this reason, we performed a prospective multicenter trial to reduce the memory bias and further increase the evidence of the results. From February 2018 to March 2019, 37 female patients aged between 18 and 80 years, underwent mastectomy or quadrantectomy with pathologic scarring and chronic persistent neuropathic pain, compatible with PMPS, are been included in the study and treated with autologous fat grafting. During the enrollment phase, patients were asked to estimate pain using the Visual Analogue Scale (VAS) and POSAS questionnaire in order to evaluate scar outcomes. The VAS scale, starting from 6.9 (1.3), decreased in the first month by 3.10 (1.59), continuing to fall by 0.83 (1.60) to 3 months and by 0.39 (2.09) at 6 months. Statistical analysis showed a significant reduction after 1 month (P < .0001) and 3 months (P < .005). All POSAS grades documented a statistically significant reduction (P < .0001) of the scores by both observers and patients. We observed that no significant association was found between age, BMI, menopausal status of patients, days from oncologic surgery to autologous fat grafting and reduction of VAS values over time while both smoking and axillary dissection were observed as the main factor significantly associated with a reduced clinical efficacy (respectively, P = .0227 and P = .0066). Our prospective multicenter trial confirms the efficacy of fat grafting in the treatment of PMPS based on the principle of regenerative medicine with a satisfactory response in terms of pain reduction and improvement of the quality of the treated tissues. Clinical questionnaires show that the cicatricial areas improve in terms of color, thickness, skin pliability, and surface irregularities. Regenerative effect is based also on the adoption of needles. The combined effect of fat grafting and needles determines a clinical full response

appraisal of clinical complications after 23 827 oocyte retrievals in a large assisted reproductive technology program

Objective To assess complications encountered after transvaginal oocyte retrieval procedures. Design Retrospective analysis. Setting University hospital, fertility center. Patient(s) A total of 23,827 consecutive transvaginal oocyte retrieval procedures in 12,615 patients. Intervention(s) Oocyte retrieval procedures performed between June 1996 and October 2016. Main Outcome Measure(s) All oocyte retrieval complications. Those requiring hospital admission for at least 24 hours were considered severe. Result(s) A total of 96 patients (0.76 %) suffered complications, with hospital admission necessary for 71 patients (0.56 %). When calculated per retrieval, the overall complication rate was 0.4%, whereas 0.29% was the admission rate, with an average duration of hospital stay of 2.77 ± 2.5 days. A surgical procedure was necessary for 24 patients (0.1% per retrieval and 0.19% per patient). Multivariate analysis showed a significant correlation between complications and women age, body mass index (BMI), the number oocyte retrieved, and the mean time to complete oocyte retrieval. The incidence of complications was significantly higher for physicians who had performed 250 retrievals (odds ratio 0.63, 95% confidence interval 0.40–0.99). Conclusion(s) Oocyte retrieval can be considered a safe procedure but is not without risks. The most important, identifiable, risk factors for the occurrence of complications are: [1] high number of oocytes retrieved, [2] a long duration of the procedure and mean time per oocyte retrieved, [3] inexperience of the surgeon, [4] younger patients with a lesser BMI, and [5] history of prior abdominal or pelvic surgery or pelvic inflammatory disease. Clinical Trial Registration Number NCT03282279

An Observational Retrospective Cohort Trial on 4,828 IVF Cycles Evaluating Different Low Prognosis Patients Following the POSEIDON Criteria

Objective: To study the actual controlled ovarian stimulation (COS) management in women with suboptimal response, comparing clinical outcomes to the gonadotropins consume, considering potential role of luteinizing hormone (LH) addition to follicle-stimulating hormone (FSH).Design: Monocentric, observational, retrospective, real-world, clinical trial on fresh intra-cytoplasmic sperm injection (ICSI) cycles retrieving from 1 to 9 oocytes, performed at Humanitas Fertility Center from January 1st, 2012 to December 31st, 2015.Methods: COS protocols provided gonadotropin releasing-hormone (GnRH) agonist long, flare-up, short and antagonist. Both recombinant and urinary FSH were used for COS and LH was added according to the clinical practice. ICSI outcomes considered were: gonadotropins dosages; total, mature, injected and frozen oocytes; cumulative, transferred and frozen embryos; implantation rate; pregnancy, delivery and miscarriage rates. Outcomes were compared according to the gonadotropin regimen used during COS.Results: Our cohort showed 20.8% of low responders, defined as 1-3 oocytes retrieved and 79.2% of "suboptimal" responders, defined as 4-9 oocytes retrieved. According to recent POSEIDON stratification, cycles were divided in group 1 (6.9%), 2 (19.8%), 3 (11.7%), and 4 (61.5%). The cohort was divided in 3 groups, according to the gonadotropin's regimen. Women treated with FSH plus LH showed worst prognostic factors, in terms of age, basal FSH, AMH, and AFC. This difference was evident in suboptimal responders, whereas only AMH and AFC were different among treatment groups in low responders. Although a different result, in terms of oocytes and embryos detected, major ICSI outcomes (i.e., pregnancy and delivery rates) were similar among groups of COS treatment. Outcomes were significantly different among Poseidon groups. Implantation, pregnancy and delivery rates were significantly higher in Poseidon group 1 and progressively declined in other POSEIDON groups, reaching the worst percentage in group 4.Conclusions: In clinical practice, women with worst prognosis factors are generally treated with a combination of LH and FSH. Despite low prognosis women showed a reduced number of oocytes retrieved, the final ICSI outcome, in terms of pregnancy, is similarly among treatment group. This result suggests that the LH addition to FSH during COS could improve the quality of oocytes retrieved, balancing those differences that are evident at baseline

low molecular weight heparin in women with repeated implantation failure

Implantation failure is common in assisted reproduction techniques (ART). The role of low-molecular-weight heparin (LMWH) is a matter of debate as a potential factor to improve implantation. Aim: To evaluate the pregnancy rate in patients with or without heparin administration. Materials & methods: We performed a retrospective observational analysis of patients with at least two IVF/intracytoplasmic sperm injection cycles with implantation failure, screened for inherited thrombophilia and submitted to further ART cycles with or without administration of LMWH. A total of 265 patients fulfilled the enrollment criteria. Of these 149 (56%) were primary infertile and 116 (44%) were secondary infertile. Their mean age was 36.3 ± 3.6 years. We analyzed basal FSH, smoking habit, gene variants for inherited thrombophilia (i.e., MTHFR C677T, prothrombin G202A10G and Factor V Leiden). The patients underwent 569 new ART cycles: 512 (90%) without and 57 (10%) with LMWH. Results: In total 105 clinical pregnancies were ..

No difference at two years between all inside transtibial technique and traditional transtibial technique in anterior cruciate ligament reconstruction

Background: one of the most recent technique is the “all inside” anterior cruciate ligament (ACL) reconstruction. One of the main characteristic ofthis procedure is the sparing of the tibial cortex. Furthermore, the all-inside technique requires only one tendon harvested. Purpose: the present study describes two year clinical outcomes of the all-inside method for ACL reconstruction, and compares them with clinical results of a group of patients treated with the traditional transtibial single-bundle ACL reconstruction technique using the semitendinosus and gracilis tendons (ST-G). Study design: pilot study, using historical controls. Methods: ACL reconstruction was performed on two groups of 20 patients each. The patients in one group underwent the all-inside transtibial technique with ST tendon alone. The second group underwent ACL reconstruction with the traditional transtibial single-bundle procedure using quadrupled ST-G tendons. Follow up at 24 months was undertaken using the IKDC, VAS pain score, Lysholm and Tegner scales. Results: the VAS pain score for the traditional ACL group was 84.6 ± 12.6; whereas the score for the all-inside group was 81.6 ± 13.1, with no statistically significant differences between the two groups. In the traditional ACL reconstruction group the Lysholm scale gave a “good results” for 7 patient (35%) and “excellent results” for 13 patients (65%) and the all-inside group gave “sufficient results” for 4 patients (20%), “good results” for 7 patients (35%) and “excellent results” for 9 patients (45%) (n.s.). The median of Tegner score was 6.5 (2-10) for the standard method group and 6 (1-9) for the all-inside group (n.s). The IKDC evaluated 50% of patients from the standard technique group as class A, and 45% as class B and 5% as class C. As regards patients of the all inside technique 55% were class A, 40% class B and, here too, just 5% scored as class C. No patients were classed as group D in each group. Conclusions: this study suggests that, in respect to return to sports and adequate articular function, there are no differences between the all-inside transtibial ACL reconstruction technique and the traditional transtibial ACL reconstruction using ST-G. The role of all-inside transtibial ACL reconstruction remains dubious. Level of evidence: III or Level C according with Oxford Center of EB

Effect of superoxide dismutase supplementation on sperm DNA fragmentation

Background: antioxidants supplementation improves sperm quality, but few trials have analyzed the effects on sperm DNA fragmentation (SDF). This study compares the effectiveness of SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol in reducing SDF with other antioxidants without SOD, hydroxytyrosol, and carnosol. Materials and methods: men with high SDF at baseline were selected in our clinical database. The patients taken into account had a 2-month control. SDF was measured by Sperm Chromatin Dispersion test (SCD). Untreated men were used as a control group. The remaining subjects received some oral antioxidant supplements (12 different combinations of both hydrophilic and lipophilic antioxidants), with some of them receiving nutritional support with a SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol. Results: 118 men were selected for a retrospective study. Mean age 39.3 ± 5.4 years. Fifteen had no treatment, 55 were treated with a SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol, and 48 took some antioxidant supplements for 2 months. Clinically, variations of at least 10% in baseline values of classic semen parameters and sperm DNA fragmentation were taken into consideration. Classic seminal parameters did not vary significantly in the three groups, with the exception of viability (p = 0.001). We assessed which of the active substances (no. 19) in different formulations were associated with variations in SDF. In the multivariable analysis of the 7 active substances that passed the univariable analysis, only the SOD molecule appeared to be linked to an improvement in SDF (&lt; 0.0001). In detail, only one patient in the control group showed a spontaneous improvement in SDF (6%), compared to 16/48 (33%) of those taking various oral antioxidant supplements, and 31/55 (56%) of those taking a SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol. Conclusions: SOD-based antioxidant supplementation plus hydroxytyrosol and carnosol seems to provide a better chance of improving sperm DNA integrity than other classical antioxidant molecules

Dataset related to article "Clinical and radiological outcomes of an uncemented metaphyseal short stem at minimum 10 years of follow‑up: a prospective observational study".

This record contains raw data related to article "Clinical and radiological outcomes of an uncemented metaphyseal short stem at minimum 10 years of follow‑up: a prospective observational study" Abstract Purpose: There is growing interest around short stems as they provide a less invasive approach for total hip arthroplasty preserving bone stock for a possible revision surgery if required. The main purpose of this work was to assess the long-term performance of an uncemented metaphyseal short stem in terms of survival rate and in addition its clinical and radiological outcomes. Materials and methods: From January to December 2010, we prospectively enrolled all consecutive patients undergoing primary total hip arthroplasty with an uncemented metaphyseal short stem in our institution with a minimum follow-up of 10 years. The radiographic features investigated were the varus-valgus stem orientation, areas of osteolysis and radiolucencies, stress shielding, and heterotopic calcifications. The clinical outcomes were measured using the HHS. Results: A total of 163 patients (172 hips) were finally included and the measured survival rate at 10 years was 99.6%. The average HHS increased from 55.0 preoperatively to 97.8 at the last follow-up (p < 0.0001). Among them, 137 patients (164 hips) were also available for radiographic assessment. Mild varus malalignment was observed in 40% of cases and remained stable in the serial X-rays and was not associated with step loosening. Mild stress shielding was observed around 13 stems (9%) and moderate only around 3 implants. Conclusion: In conclusion, the uncemented metaphyseal short stems showed excellent survival and clinical results at 10 years and at a radiographical level very low stress shielding was observed; moreover, besides the high frequency of varus alignment the implanted stems was not associated with revision surgery or with worse clinical outcomes.
