Abstract
PURPOSE OF REVIEW Gynecological cancer is a very important cause of comorbidity and mortality in women. The current delay in motherhood is increasing the incidence of women under 40 years of age that have not yet achieved their maternity goals when they are diagnosed and standard treatment negatively impacts the reproductive potential of cancer survivors. In this review, we update the information available about the safety of fertility-sparing treatments in young gynecological cancer patients, as well as the safety and efficacy of assisted reproductive techniques (ART) in such group. We also evaluate the long-term gynecological cancer risk in women requiring ART. RECENT FINDINGS Although eligibility criteria continue to be very strict, there are more and more reports of fertility-sparing approaches outside of what traditionally has been considered safe. Molecular assessment is starting to be used in the selection of appropriate candidates. Data increasingly shows the long term safety and the efficacy of ART and pregnancy in these patients. SUMMARY Appropriate selection is key to safely preconize fertility-sparing alternatives. Because subfertility may be a result of these procedures, ART could be indicated in this setting. Neither ART nor pregnancy appear to increase recurrences or affect survival rates.

Abstract
OBJECTIVE The primary objective was to evaluate the response rate of conservative treatment for endometrial cancer, and the secondary objective was to assess oncological, fertility and obstetric outcomes in patients who underwent fertility preservation treatment. MATERIAL AND METHODS This multicentre, observational, retrospective study evaluated endometrial cancer patients who underwent fertility-sparing treatment in Spanish centres between January 2010 and January 2020. Seventy-three patients with stage IA endometrioid adenocarcinoma of the uterus were included in the study. RESULTS The levonorgestrel intrauterine device (LNG-IUD) was the most common fertility-sparing treatment (53.4%), followed by megestrol acetate (20.5%) and medroxyprogesterone acetate (16.4%). During the 24-month follow-up period, the rate of complete response to fertility-sparing management was 74% (n = 54), and 8.2% (n = 6) of patients presented a partial response. Additionally, 13 (17.8%) patients presented with persistent disease and six (8.2%) relapsed after response. The LNG-IUD was associated with a higher complete response rate than the other methods (87.2 vs. 58.8%; p = 0.01). Surgical treatment (at least hysterectomy) was performed in 44 (60.3%) patients as the end of fertility-sparing treatment. Four (5.5%) patients presented relapse after surgery, associated with final FIGO stage III (p = 0.036), myometrial invasion > 50% (p = 0.018) and final tumour grade 2-3 (p = 0.018). The mean follow-up period was 57.8 (range 6-159) months. The 5-year relapse-free survival and overall survival rates were 92.6% [95% CI (81.3, 97.2)] and 93.5% [95% CI (80.7, 97.9)], respectively. During follow-up, three patients (4.1%) died of the disease after completion of surgical treatment. Up to 50.7% of patients included in the study attempted to get pregnant. Of these, the rate of pregnancy was 81.1% (n = 30/37), and reproductive techniques were used for this purpose in 78.4% of cases. CONCLUSIONS Fertility-sparing management presented a high response rate in patients with endometrial cancer. LNG-IUD was associated with a better response rate compared to the other treatment options. Moreover, in patients using this management method, pregnancy could be achieved using reproductive techniques.

Abstract
BACKGROUND Living donation is a potential source of organs that could help to reduce the organ transplant deficit. Given that we have a worldwide aging population, it is important to assess the opinion of older people toward this type of donation. OBJECTIVES To analyze the attitude of people aged > 65 years toward living kidney donation (LKD) and living liver donation (LLD) and to investigate the variables affecting their attitudes. METHODS A multicentric study was carried out using a representative sample of people > 65 years stratified by sex and geographic location in southeastern Spain (n = 420). The measurement instrument was a validated questionnaire about LKD and LLD. Statistics were analyzed using SPSS version 21.0 (IBM Corp, Armonk, NY, United States) software. Descriptive analysis was carried out using Student t test, χ2 test, and a multivariate analysis. RESULTS The questionnaire completion rate was 84% (n = 351) with 88% (n = 310) in favor of LKD, and 89% (n = 311) in favor of LLD. Favorable attitude decreased to 3% when the donation under consideration was unrelated. Attitudes toward LKD and LLD were associated with having received information from the television (P = .016 and P = .045) and from friends (P = .017 and P = .03); accepting an autopsy after death (P = .001 and P = .002); and not being worried about scars (P = .015 and P = .044). In the multivariate analysis, the following variables continued to be significant: having received information from the television (odds ratio [OR], 2) and from friends (OR, 10.3); and the acceptance of an autopsy (OR, 2). CONCLUSIONS Older people are in favor of both LKD and LLD, assuming it is a related donation. In addition, the information the elderly population receives regarding organ donation and transplantation affects their attitudes.

Abstract
RESEARCH QUESTION Does ovarian stimulation for oocyte vitrification affect disease-free survival and overall survival rates in women with early breast cancer? DESIGN This cohort study included 259 patients with early breast cancer; 148 patients underwent ovarian stimulation, whereas 111 patients did not. Patients were treated between January 2008 and December 2016. To calculate the disease-free survival time and overall survival rate, the time of definitive surgery was defined as the starting point. The follow-up was conducted up to 5 years. RESULTS Exposed and non-exposed groups were comparable in tumour, node and metastases classification, Nottingham grade, hormonal receptor status, tumour molecular phenotype, histology and pathology stage. The exposed group was younger than the non-exposed. Recurrences occurred in 9/148 women (6.1%) in the exposed group and 15/111 women (13.5%) in the non-exposed group, with no significant difference. The mean disease-free survival time was 63.9 months (95% confidence interval [CI]: 61.5-66.4) in the exposed group and 60.6 months (95% CI: 56.9-64.2) in the non-exposed, with no significant difference (log-rank [Mantel-Cox] test). Overall survival rates were comparable; 2/148 (1.4%) and 4/111 (3.6%) patients died, in exposed and non-exposed groups, respectively, during the period analysed. Mean overall survival times were 67.2 months (95% CI: 66.2-68.2) in the exposed group and 65.9 months (95% CI: 64.0-67.9) in the unexposed, with no significant difference (log-rank [Mantel-Cox] test). CONCLUSIONS This study suggests that ovarian stimulation in patients with early-stage breast cancer is safe in the long term.

Abstract
STUDY QUESTION Is the indication for fertility preservation (FP) related to success in IVF cycles after elective-FP (EFP) for age-related fertility decline and FP before cancer treatment (Onco-FP)? SUMMARY ANSWER Although success rates were lower in cancer patients, there was no statistically significant association between malignant disease and reproductive outcome after correction for age and controlled-ovarian stimulation (COS) regime. WHAT IS KNOWN ALREADY FP is increasingly applied in assisted reproduction, but little is known about the outcome of IVF cycles with vitrified oocytes in FP patients. STUDY DESIGN, SIZE, DURATION Retrospective, observational multicenter study of vitrification cycles for FP and of the warming cycles of women who returned to attempt pregnancy from January 2007 to May 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS In all, 6362 women (EFP = 5289 patients; 7044 cycles + Onco-FP = 1073 patients; 1172 cycles) had their oocytes vitrified for FP. A logistic regression analysis was performed to examine the impact of indication for FP corrected for age at vitrification. The protocol used for COS was also included as a possible confounder. The main outcome measures were oocyte survival and live birth. A detailed description of the baseline and clinical data is provided, with comparisons between EFP and Onco-FP. The cumulative live birth rate (CLBR) per utilized oocyte according to age at vitrification was analyzed in those patients returning to use their oocytes. MAIN RESULTS AND ROLE OF CHANCE Age at vitrification was significantly older in EFP patients (37.2 ± 4.9 vs. 32.3 ± 3.5 year; P < 0.0001). Fewer oocytes were retrieved and vitrified per cycle in EFP (9.6 ± 8.4 vs. 11.4 ± 3.5 and 7.3 ± 11.3 vs. 8.7 ± 2.1, respectively; P < 0.05), but numbers became comparable when analyzed per patient (12.8 ± 7.4 vs. 12.5 ± 3.2 and 9.8 ± 6.4 vs. 9.5 ± 2.6). Storage time was shorter in EFP (2.1 ± 1.6 vs. 4.1 ± 0.9 years; P < 0.0001). In all, 641 (12.1%) EFP and 80 (7.4%) Onco-FP patients returned to attempt pregnancy (P < 0.05). Overall oocyte survival was comparable (83.9% vs. 81.8%; NS), but lower for onco-FP patients among younger (≤35 year) subjects (81.2% vs. 91.4%; P > 0.05). Fewer EFP cycles finished in embryo transfer (50.2% vs. 72.5%) (P < 0.05). The implantation rate was 42.6% and 32.5% in EFP versus Onco-FP (P < 0.05). Ongoing pregnancy (57.7% vs. 35.7%) and live birth rates (68.8% vs. 41.1%) were higher in EFP patients aged ≤35 than the Onco-FP matching age patients (P < 0.05). The reason for FP per se had no effect on oocyte survival (OR = 1.484 [95%CI = 0.876-2.252]; P = 0.202) or the CLBR (OR = 1.275 [95%CI = 0.711-2.284]; P = 0.414). Conversely, age (<36 vs. ≥36 y) impacted oocyte survival (adj.OR = 1.922 [95%CI = 1.274-2.900]; P = 0.025) and the CLBR (adj.OR= 3.106 [95%CI = 2.039-4.733]; P < 0.0001). The Kaplan-Meier analysis showed a significantly higher cumulative probability of live birth in patients <36 versus >36 in EFP (P < 0.0001), with improved outcomes when more oocytes were available for IVF. LIMITATIONS, REASONS FOR CAUTION Statistical power to compare IVF outcomes is limited by the few women who came to use their oocytes in the Onco-FP group. The patients' ages and the COS protocols used were significantly different between the EFP and ONCO-PP groups. WIDER IMPLICATIONS OF THE FINDINGS Although the implantation rate was significantly lower in the Onco-FP patients the impact of cancer disease per se was not proven'. EFP patients should be counseled according to their age and number of available oocytes. STUDY FUNDING/COMPETING INTEREST(S) No external funding was used for this study. The authors have no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
Isotretinoin (13-cis-retinoic acid) is a pharmaceutical vitamin A analog that is frequently used in the treatment of severe cystic acne, many women at reproductive age being exposed to this substance. This drug has a clearly documented teratogenicity and data from rodents and humans indicate that a direct aggression to ovarian follicles also occurs. Here we report the case of a 29-year-old woman with breast cancer referred for emergency preservation of reproductive potential that used isotretinoin up to the day before the initiation of ovarian stimulation. Ultrasound scan showed an antral follicle count of 17 and 13 follicles on the right and the left ovary, respectively, and her antimüllerian hormone levels were 4.03 ng/ml. Standard ovarian stimulation for oocyte vitrification in oncological patients was initiated during the luteal phase and final estradiol levels were 49 pg/ml. Three mature oocytes were obtained. Other four oocytes were retrieved in the germinal vesicle and metaphase I developmental stage, all of which matured in vitro in the following 30 h and were also vitrified. Response to ovarian stimulation, both in terms of the number of mature oocytes obtained and serum sex steroids production were in the lower range of what is observed in patients with a similar clinical profile. These findings suggest that isotretinoin impairs follicular-oocyte maturation.

Abstract
PURPOSE OF REVIEW It is necessary to clarify the fertility preservation-related points of concern that often frighten patients or physicians when it comes to deciding about oocyte cryopreservation for fertility preservation, which are often perceived as procedure limitations, are sometimes real and often theoretical and may make the prognosis worse. RECENT FINDINGS Letrozole added to gonadotrophins for controlled ovarian stimulation is safe when applied to hormone-sensitive cancer patients as it avoids associated high estradiol levels. This benefit is only for estrogens, but not for progesterone. Triggering ovulation with gonadotropin releasing hormone agonist bolus and adding the gonadotropin releasing hormone antagonist after oocyte retrieval help minimize its effect. A random start is currently widespread as neither results nor offspring are compromised, and it avoids waiting for menstruation and, therefore, delaying treatment. SUMMARY The cumulative live birth rate is conditioned by the number of available oocytes and patient's age. Assisted reproductive technologies may help cancer patients to achieve pregnancy with good obstetric outcomes and apparent oncological safety. Although counseling should be provided on an individual basis, fertility preservation in cancer patients and later pregnancy in survivors after adequate treatment and follow-up should not be discouraged.

Abstract
OBJECTIVE To provide a detailed description of the current oocyte vitrification status as a means of elective fertility preservation (EFP). DESIGN Retrospective observational multicenter study. SETTING Private university-affiliated center. PATIENT(S) A total of 1,468 women who underwent EFP because of age or having associated a medical condition other than cancer (January 2007 to April 2015). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Survival and cumulative live birth rate (CLBR) per consumed oocyte. RESULT(S) Mean age was higher with EFP due to age versus having an associated medical reason (37.7 y [95% confidence interval (CI) 36.5-37.9] vs. 35.7 y [95% CI 34.9-36.3]). In total, 137 patients (9.3%) returned to use their oocytes. Overall survival rate was 85.2% (95% CI 83.2-87.2). Live birth rate per patient was higher in women ≤35 years old than ≥36 years old (50% [95% CI 32.7-67.3] vs. 22.9% [95% CI 14.9-30.9]). CLBR was higher and increased faster in younger women. The gain in CLBR was sharp from 5 (15.4%, 95% CI -4.2 to 35.0) to 8 oocytes (40.8%, 95% CI 13.2-68.4), with an 8.4% gain per additional oocyte, in the ≤35-year-old group. The increase was slower with 10-15 oocytes, reaching a plateau CLBR of 85.2%. A milder increase (4.9% gain) was observed in the ≥36-year-old group (from 5.1% [95% CI -0.6 to 10.7] to 19.9% [95% CI 8.7-31.1] when 5-8 oocytes were consumed), reaching the plateau with 11 oocytes (CLBR 35.6%). Forty babies were born. CONCLUSION(S) At least 8-10 metaphase II oocytes are necessary to achieve reasonable success. Numbers should be individualized in women >36 years old. We suggest encouraging women who are motivated exclusively by a desire to postpone childbearing because of age, to come at younger ages to increase success possibilities.

Abstract
The purpose of this study is to report the long-term follow-up result of allograft reconstruction of segmental defect of the humeral head associated with posterior dislocation of the shoulder. Six men underwent operative management of defects of the humeral head involving 40% of the articular surface, following posterior dislocation of the humeral head. The period of time between dislocation and surgery ranged from 7 to 8 weeks. The defect in the head was filled with an allogeneic segment of humeral head contoured to restore the spherical shape. All the patients returned to their occupation 4 months later. All the cases were evaluated clinically and by radiographs and computed tomography (CT) scan at a mean of 122 (96-144) months after the operative procedure. Three men had no complaints of pain, instability, clicking or catching, whereas three had pain, clicking, catching and stiffness. The three patients with good clinical result showed also good radiographic result. The computed tomography (CT) confirmed incorporation of the allograft and no osteoarthrosis. Another patient had a good clinical and radiographic result until the eighth postoperative year. At 8-year follow-up examination, this patient developed shoulder osteoarthrosis and he had pain and stiffness. He needed an arthroplasty 10 years after the operation. The other two patients developed collapse of the graft and osteoarthrosis that were yet evident at 4-year follow-up. These patients required a shoulder arthroplasty 8 years after the procedure. We conclude that the treatment of segmental defects of the humeral head associated with posterior dislocations of the shoulder by allograft reconstruction has a good long-term follow-up result in 50% of the patients.

Abstract
The aim of this review is to provide current knowledge on oocyte cryopreservation, with special emphasis on vitrification as a means to preserve fertility in different indications. Major advancements achieved in the past few years in the cryolaboratory have facilitated major changes in our practice. Areas such as fertility preservation for social or oncologic reasons, the possibility to create oocyte banks for egg donation programs, the opportunity to avoid ovarian hyperstimulation syndrome, or to accumulate oocytes in low-yield patients, or even to offer treatment segmentation by stimulating the ovaries, vitrifying, and then transferring in a natural cycle are some of the options that are now available with the development of cryopreservation. We present general experience from our group and others on fertility preservation for age-related fertility decline as well as in oncologic patients, confirming that oocyte vitrification is a standardized, simple, reproducible, and efficient option.

Abstract
OBJECTIVE To evaluate the usefulness of preimplantation genetic screening (PGS) using fluorescence in situ hybridization (FISH) for two different indications: repetitive implantation failure (RIF) and advanced maternal age (AMA). DESIGN Two prospective, randomized controlled trials with patients allocated in two arms: blastocyst transfer on day 5 (group A) or PGS with transfer on day 5 (group B). SETTING University-affiliated private clinics. PATIENT(S) The RIF study included women <40 years with three or more failed IVF cycles without other known causal factors (91 patients). The AMA study included intracytoplasmic sperm injection patients aged between 41 and 44 (183 patients). INTERVENTION(S) In the PGS group, single-cell day 3 biopsy was performed with aneuploidy screening for chromosomes 13, 15, 16, 17, 18, 21, 22, X, and Y. In both the blastocyst transfer group and the PGS group, ET was performed on day 5. MAIN OUTCOME MEASURE(S) Live-birth rate per patient and per started cycle. RESULT(S) A significant increase in live-birth rates per patient was found in the PGS group compared with the blastocyst group for the AMA study (30/93 patients [32.3%] vs. 14/90 patients [15.5%]; odds ratio, 2.585; confidence interval, [1.262-5.295]). In the RIF study no significant differences were observed (23/48 patients [47.9%] vs. 12/43 patients [27.9%]). CONCLUSION(S) PGS with FISH was shown to be beneficial for the AMA group.

Abstract
The registration of 2D and 3D images is one of the key tasks in medical image processing and analysis. Accurate registration is a crucial preprocessing step for many tasks; consequently, the evaluation of its accuracy becomes necessary. Unfortunately, this is a difficult task, especially when no golden pattern (true result) is available and when the signal values may have changed between successive images to be registered. This is the case this paper deals with: we have a series of 3D images, magnetic resonance images (MRI) of the liver and adjacent areas that have to be registered. They have been taken while a contrast is diffused through the liver tissue, so intensity of each observed point changes for two reasons: contrast diffusion/perfusion and deformation of the liver (due to body movement and breathing). In this paper, we introduce a new method to automatically compare two or more registration algorithms applied to the same case of a perfusion magnetic resonance dynamic image so that the best of them can be chosen when no ground truth is available. This is done by modeling the function that gives the intensity at a given point as a functional datum, and using statistical techniques to assess its change in comparison with other functions. An example of the application is shown by comparing two parametrizations of a B-spline based registration algorithm. The main result of the proposed method is a suggestive evidence to guide the physician in the process of selecting a registration algorithm, that recommends the algorithm of minimal complexity but still suitable for the case to be analyzed.

Abstract
We report on the first measurement of the F(2) structure function of the neutron from the semi-inclusive scattering of electrons from deuterium, with low-momentum protons detected in the backward hemisphere. Restricting the momentum of the spectator protons to ≲100 MeV/c and their angles to ≳100° relative to the momentum transfer allows an interpretation of the process in terms of scattering from nearly on-shell neutrons. The F(2)(n) data collected cover the nucleon-resonance and deep-inelastic regions over a wide range of Bjorken x for 0.65<Q(2)<4.52 GeV(2), with uncertainties from nuclear corrections estimated to be less than a few percent. These measurements provide the first determination of the neutron to proton structure function ratio F(2)(n)/F(2)(p) at 0.2≲x≲0.8 with little uncertainty due to nuclear effects.

Abstract
OBJECTIVE To evaluate the results of controlled ovarian stimulation before chemotherapy for oocyte vitrification to preserve fertility in women diagnosed with cancer and compare them with a historical control group. DESIGN A retrospective, multicenter, observational study performed between March 2007 and January 2011. SETTING University-affiliated infertility clinics. PATIENT(S) Of 272 patients affected by cancer in our Fertility Preservation Program, 223 women underwent a stimulated cycle for oocyte vitrification according to our protocols before cancer treatment. Their results were compared with a historical control group of 98 patients diagnosed with male factor infertility who were stimulated for a conventional IVF cycle. INTERVENTION(S) Controlled ovarian stimulation and oocyte retrieval. MAIN OUTCOME MEASURE(S) Days of stimulation, total dose of gonadotropins, estrogen levels, and number of oocytes retrieved and vitrified. RESULT(S) No differences were found in days of stimulation, but significant differences in E(2) levels and the number of retrieved oocytes were measured, especially in the hormone-dependent cancer group. CONCLUSION(S) Patients with hormone-dependent cancer had a weaker response to controlled ovarian stimulation compared with patients with non-hormone-dependent cancer. Whether the oncological disease already affects the ovaries before chemo-/radiotherapy remains to be elucidated.

Abstract
INTRODUCTION The use of elderly donors can increase the pool of organs available for transplant. The aim of this study was to analyze the outcomes of grafts from donors older than 75 years. PATIENTS AND METHODS We selected 29 patients transplanted from January 2003 to January 2010 with livers from donors older than 75 years for comparison with a control group (58 patients), selected among patients transplanted immediately before or after each study case. Data analyzed using SPSS 15.0 were considered statistically significant at P < .05. RESULTS Statistically significant differences were evident in the mean age of donors (78.3 ± 2.9 vs 50.4 ± 17.8 years, P < .001), levels of aspartate aminotransferase alanine aminotransferase (30.8 ± 18.13/24.9 ± 14.4 vs 53.81 ± 68.4/39.37 ± 39.94 U/L, P < .05), and waiting list time of (122.4 ± 94.3 vs 169.2 ± 135.5 days, P = .034) of elderly donor versus control graft cohorts. The median follow-up was 32 months (range: 4-88.0) No differences were observed at 1 and 3 years after transplantation: graft survival was 78% and 61% in the older donor group and 83% and 71% in the younger donor group, respectively. CONCLUSION The use of expanded donors from elderly subjects can increase the donor pool with good results.

Abstract
The best treatment for hepatocellular carcinoma (HCC) associated with liver cirrhosis is liver transplantation and the best results are obtained when the tumors fulfill the Milan criteria. However, although the number of transplants is increasing, the organ deficit is growing, which lengthens time on the waiting list, increasing the risk of tumor progression of and exclusion from the list. The use of elderly donors is a valid option for patients on the transplant waiting list with HCC, reducing time on the waiting list. We report our experience with patients transplanted for HCC associated with hepatic cirrhosis using livers from donors >75 years of age. Our preliminary results supported the use of elderly suboptimal donors making it possible to give priority to these patients. All patients in the series achieved good graft function after a follow-up of 2 years with a 100% disease-free survival rate. More extensive long-term studies are needed to confirm these findings.

Abstract
The purpose of this article was to report an arthroscopic treatment method for greater tuberosity malunion. Eight patients with malunion of the greater tuberosity were treated by arthroscopic acromioplasty, detachment of rotator cuff, tuberoplasty of the greater tuberosity and repair of the rotator cuff. On the basis of the UCLA rating scale, the overall score increased from 11.1 (range 9-14) to 30.2 (range 25-35) postoperatively, with one excellent result, six good results, and one poor result. All patients had less pain than preoperatively. Full activity level was achieved in two patients, five patients had only slight functional restriction, and one patient had mild limitation in activities of daily living. Seven patients returned to their previous occupations without restrictions. One patient did not return to work because of residual upper extremity weakness. We conclude that arthroscopic tuberoplasty is a good method for the treatment of greater tuberosity malunion.

Furthermore, there is medical suggestive evidence of a direct relationship between certain measures of vascular characteristics in the ocular fundus (arteriolar and venular calibers and focal arteriolar narrowing) and cardiovascular diseases. In order to establish such relationship on sound statistical basis a method must be provided to measure the needed values in an easy, yet precise and repeatable way. This paper presents a system to assist physicians in signaling and storing the data associated to signs of vascular deterioration and vascular calibers in non-mydriatic ocular fundus images. The system is built around a graphical user interface that, even not fully automatic, guides the practitioner to mark certain anatomic visible features in an easy and precise way. The data are exported in common database formats for further processing and a statistical summary is also presented.

Abstract
A prospective study is presented of 551 hip fractures treated with the ITST (inter-trochanteric/sub-trochanteric) nail with a minimum mandatory follow-up of 1 year. Of the patients 73% were female, the rest male. The average age was 82.8 years. Fractures were classified according to the AO system, the most common sub-type recorded being the A2 (56%). Clinical and radiographic controls were performed at 1, 3, 6 and 12 months. The system allowed early mobilisation and walking in the majority of our patients, along with fracture consolidation in an acceptable time (12 weeks on average). There were technical complications during the operation in 10.5% of the cases, complications in the immediate postoperative period in 22.3% and late complications were detected in 5.1% of patients at 12 months. The ability to recover previous walking ability was 58%. The ITST nail emerges as a good system of osteosynthesis for fractures of the trochanteric region of the femur, allowing early weight-bearing, which favours bone consolidation. The surgical technique is not complex, the number of complications recorded is acceptable and the overall results obtained are comparable and even superior to those obtained with other osteosynthesis systems available for treatment of this type of fracture.

Abstract
INTRODUCTION Oocyte cryopreservation is a useful tool for preserving the fertility of cancer patients at risk of losing ovarian function due to undergoing potentially sterilising therapies. Results obtained with different cryopreservation protocols have been disappointing, particularly those obtained with slow cooling procedures. The efficacy of vitrification as an application in clinical practice has recently been demonstrated. The aim of this study is to report results obtained with the Cryotop method of oocyte vitrification in a population of healthy women and to point out its potential usefulness for fertility preservation in oncological patients. MATERIALS AND METHODS The study population consisting of non-oncological patients included 47 oocyte donors and 57 recipients undergoing an oocyte donation cycle of assisted reproductive technology (ART). A total of 693 mature metaphase II oocytes were collected following ovarian stimulation using long protocol down-regulation plus gonadotropin administration. Vitrification was carried out by means of the Cryotop method. Oocytes were donated to a compatible recipient after endometrial preparation. RESULTS Of the 693 oocytes, 666 (96.1%) survived. A total of 487 (73.1%) were fertilised successfully. One hundred and seventeen embryos were transferred to 57 recipients. Pregnancy rate per transfer and implantation rates were 63.2% and 38.5% respectively. Twenty-eight healthy babies were later born. CONCLUSIONS Oocyte cryo-banking by means of the Cryotop vitrification method represents a viable option for healthy women, producing excellent survival rates and a clinical outcome similar to that obtained with fresh oocytes. This approach could potentially be used in cancer patients who want to safeguard their fertility. Cancer patients could potentially benefit from this approach by storing their oocytes before the onset of the oncological therapy.

Abstract
The Cryotop vitrification method has been shown to be a very useful tool for oocyte cryopreservation, giving excellent results regarding survival and clinical outcome. There are several clinical situations in which oocyte cryopreservation provides solutions that have not been available to date. This report describes three of these situations: (i) a low-responder patient who needed a single gene diagnosis due to the presence of a genetic disease; (ii) a patient undergoing endometrial bleeding on the day of oocyte retrieval who was also affected by a genetic disorder; and (iii) a patient who failed to become pregnant after the donation of vitrified oocytes and subsequently had the re-vitrified surplus embryos transferred. The resolution of these cases provides evidence of the enormous potential of the Cryotop method as a tool within assisted reproduction technology.

Abstract
Six men underwent operative management of defects of the humeral head involving at least 40% of the articular surface, following posterior dislocation of the humeral head. The cause of dislocation was a grand mal seizure in three and a fall in three cases. In five cases the dislocation was reduced under general anaesthesia, and in all the posterior dislocation recurred early. Time between dislocation and surgery ranged from 7 to 8 weeks. The defect in the head, revealed by CT, was filled with an allogeneic segment of humeral head contoured to restore the spherical shape. All the patients returned to their occupation 4 months later. The mean duration of follow-up was 62.6 (60-68) months. At discharge, four of the men had no complaints of pain, instability, clicking or catching; two had pain, clicking, catching and stiffness. Radiographs and CT revealed no failures of fixation or of incorporation of the allograft. In four cases the contour and volume of the graft were maintained, but in the two with a bad clinical result, flattening and collapse of the graft and osteoarthrosis were observed. If the procedure fails, prosthetic reconstruction should be simple because the skeletal anatomy has not been distorted.

Abstract
Rotator interval tear is one of the lesions identified in patients with glenohumeral instability. We present our technique for arthroscopic interval capsule repair. After having performed Bankart reconstruction, we pull the anterosuperior cannula back some millimeters and introduce a Penetrator suture retriever forceps (Arthrex, Naples, FL) through the upper interval capsule into the joint. Then we also remove some millimeters of the anterior cannula and introduce a suture passer (Spectrum; Linvatec, Largo, FL) loaded with a monofilament suture through the lower interval capsule. The suture is pushed into the joint and, using the Penetrator suture retriever forceps, we retrieve it out of the joint. This suture is replaced if desired by a permanent braided suture. Next, a suture passer (Arthrex) advances the end of the suture from the anterosuperior portal into the joint. The suture is retrieved out of the joint from the anterior cannula with a crochet hook. We tie the suture down the anterior cannula to close the anterior capsule. Because we use cannulas, we can use a sliding knot. The degree of tightening can be observed directly under arthroscopic view but the knot is outside of the capsule. We believe that this method is easy, effective, and reproducible.

Abstract
We present the results of a retrospective study of the epidemiology of distal forearm fractures in patients over 15 years of age in Zaragoza (Spain) during 1998-1999. We analysed a total of 2506 fractures of the distal forearm. Fractures were classified according to age, sex, Frykman classification and mechanism of injury. Fractures were Frykman type III in 23.5% of cases, Frykman II in 17.9%, Frykman IV in 14.5% and Frykman I in 12.8%. The rest of fractures were distributed homogeneously between the remaining fracture types. The mechanisms of injury was low energy in 78.2% of cases and high in 21.8%. Analysis of the age distribution showed an increase in the incidence of this type of fracture over 50 years of age, with a peak between 60 and 69 years as a result of accidental falls. We found an increased incidence in males below 49 years of age, as a result of traffic accidents, and a predominance of females over 50 years of age due to osteoporosis and an increased number of falls.

Abstract
One hundred and ninety three parental lines obtained from 26 countries for an international rice molecular breeding program were evaluated using 101 well-distributed simple sequence repeat (SSR) markers. An overall genetic diversity of 0.68 and an average of 6.3 alleles per locus were revealed, indicating a high level of genetic variation in these lines. Cluster analysis of the 193 accessions showed three major groups and nine subgroups. Group I corresponded to the classical indica subspecies, whereas groups II and III belong to the japonica subspecies. Indica and japonica differentiation accounted for only 6.5% of the total variation in the entire sample and 93.5% was due to within-subspecies diversity. Differentiation among eco-geographic regions accounted for 24% of the diversity within the subspecies. Larger amounts of the eco-geographical differentiation were resolved within japonica than within indica. The largest indica-japonica differentiation based on the single locus level was detected by markers on chromosomes 9 and 12, while the smallest differentiation was detected by markers on chromosomes 4 and 8. Furthermore, genetic differences at the single-locus and two-locus levels, as well as components due to allelic and gametic differentiation, were revealed between indica and japonica and among the main geographic regions. The multilocus analysis in genetic diversity showed a higher proportion of variation caused by predominant non-random associations of different loci within and among the classified subspecies and geographic subdivisions. The results suggest that selection for eco-geographical adaptation on multilocus associations was largely responsible for the maintenance of the extensive variation in the primary gene pool of rice.

Abstract
OBJECTIVES To calculate the proportion of cases of dementia detected in people over 70 living in their homes and to describe the use made by people with dementia of the health and social services. MATERIAL AND METHODS Population survey of the survivors of the cohort "Growing old in Leganés", started in 1993. In the third monitoring (1999-2000), the clinical diagnosis of dementia on the basis of a neurological examination and an extensive neuro-psychological battery was included. Their use of health and social services and prior diagnoses were also asked. RESULTS In the sample of survivors (n=527), there was 12.1% prevalence of dementia. Only 30% of the demented had previously been diagnosed by the health services. The proportion of undetected dementia was significantly associated with its seriousness (light 95%, moderate 69%, severe 36%). Compared with older persons who were not demented, the demented used more often hospital services, medical and nursing consultations at home and consultations through third parties; and less often, preventive and rehabilitation services. This trend was accentuated in patients with grave dementia. The use of community social services was very low (below 8% in the most serious cases). CONCLUSIONS The detection of dementia in the elderly is very low and efforts to detect it in primary care need to be stepped up. Specific social-health resources for this population also need to be increased and the attendance guide-lines for primary care teams, and for health professionals in general, need to be changed.

Abstract
We report the result of the treatment of 26 lower limb fractures in patients with established paraplegia. We treated one fracture of the femoral neck, one intertrochanteric, two subtrochanteric, two of the femoral shaft, seven of the supracondylar region, six of the proximal tibia, one of the tibial shaft, and six pilon fractures. Nine fractures were treated non-operatively, and the remaining fractures were treated operatively. Union was achieved in all the patients, but we think that open reduction and internal fixation may improve the level of independence and mobility of these patients during fracture healing.

Abstract
The resistance of rice to its bacterial blight pathogen Xanthomonas oryzae pv. oryzae (Xoo) has both qualitative and quantitative components that were investigated using three near-isogenic line sets for four resistance (R) genes (Xa4, xa5, xa13, and Xa21) and 12 Xoo races. Our results indicate that these two resistance components of rice plants were associated with the properties of the R genes. The qualitative component of the R genes was reflected by their large effects against corresponding avirulent Xoo races. The quantitative component of the R genes was their residual effects against corresponding virulent races and their epistatic effects, which together could lead to high-level resistance in a race-specific manner. Our results revealed important differences between the different types of R genes. Two R genes, Xa4 and Xa21, showed complete dominance against the avirulent Xoo races and had large residual effects against virulent ones. They acted independently and cumulatively, suggesting they are involved in different pathways of the rice defensive system. The third R gene, xa5, showed partial dominance or additivity to the avirulent Xoo races and had relatively small but significant residual effects against the virulent races. In contrast, xa13 was completely recessive, had no residual effects against the virulent races, and showed more pronounced race specificity. There was a strong interaction leading to increased resistance between xa13 and xa5 and between either of them and Xa4 or Xa21, suggesting their regulatory roles in the rice defensive pathway(s). Our results indicated that high-level and durable resistance to Xoo should be more efficiently achieved by pyramiding different types of R genes.

Abstract
OBJECTIVE Moderate hyperhomocyst(e)inemia is an independent risk factor for stroke, but it is unclear whether it also would be a risk factor for secondary vascular events after stroke. METHODS Longitudinal study of 137 consecutive ischemic stroke patients (age 45-91 years) who were prospectively studied with a standard clinical protocol. Vascular events (stroke recurrence, ischemic heart disease, deep venous thrombosis or peripheral arterial disease) were identified during 2 years of follow-up. Serum homocyst(e)ine was determined 3 months after the stroke. The cumulative proportion of patients with homocyst(e)ine above or below the 75th percentile who survived free of vascular events was determined by Kaplan-Meier analysis. Cox models were used to estimate the relative risk of vascular events after controlling for other confounding factors. RESULTS Serum homocyst(e)ine was significantly higher in patients with vascular events (26.2 versus 19.4 micromol/l; p = 0.016). The cumulative proportion of patients with vascular events was 46.5% in the group with homocyst(e)ine over the 75th percentile (>30 micromol/l) and 20.2% in the other group (log-rank test 7.5; p = 0.0062). After adjustment for age, sex, high blood pressure, diabetes, heart disease, previous cerebrovascular disease, smoking and serum cholesterol, the relative risk of vascular event for patients above compared with those below the 75th percentile of serum homocyst(e)ine was 2.8 (CI 95% 1.3-6; p = 0.01). CONCLUSION Hyperhomocyst(e)inemia is a significant risk factor for vascular events after ischemic stroke. This finding is independent of other risk factors such as hypertension, and may have therapeutic relevance in the secondary prevention of vascular diseases in stroke patients.

Abstract
We measured the cross section and response functions for the quasielastic 16O(e,e'p) reaction for missing energies 25< or =E(m)< or =120 MeV at missing momenta P(m)< or =340 MeV/c. For 25<E(m)<50 MeV and P(m) approximately 60 MeV/c, the reaction is dominated by a single 1s(1/2) proton knockout. At larger P(m), the single-particle aspects are increasingly masked by more complicated processes. Calculations which include pion exchange currents, isobar currents, and short-range correlations account for the shape and the transversity, but for only half of the magnitude of the measured cross section.
