Abstract
Eggs and embryo manipulation is an important biotechnological challenge to enable positioning, entrapment, and selection of reproductive cells to advance into a new era of nature-like assisted reproductive technologies. Oviductin (OVGP1) is an abundant protein in the oviduct that binds reversibly to the zona pellucida, an extracellular matrix that surrounds eggs and embryos. Here, the study reports a new method coupling OVGP1 to magnetic nanoparticles (NP) forming a complex (NPOv). NPOv specifically surrounds eggs and embryos in a reversible manner. Eggs/embryos bound to NPOv can be moved or retained when subjected to a magnetic force, and interestingly only mature-competent eggs are attracted. This procedure is compatible with normal development following gametes function, in vitro fertilization, embryo development and resulting in the birth of healthy offspring. The results provide in vitro proof-of-concept that eggs and embryos can be precisely guided in the absence of physical contact by the use of magnets.

Abstract
The purpose of this State-of-the-Art Review was to provide a strategic analysis, in terms of strengths, weaknesses, opportunities and threats (SWOT analysis), of the current evidence regarding the management of uterine isthmocele (Cesarean scar defect). Strengths include the fact that isthmocele can be diagnosed on two-dimensional transvaginal ultrasound, and that surgical repair may restore natural fertility potential and prevent secondary infertility, as well as reduce the risk of miscarriage and other obstetric complications. However, there is a lack of high-quality evidence regarding the best diagnostic method and criteria, as well as the potential benefits of surgical repair with respect to fertility. There is a need for experienced surgeons skilled in the various isthmocele repair techniques. Isthmocele repair does not prevent the need for Cesarean delivery in subsequent pregnancies. There is increasing awareness regarding the accuracy of transvaginal ultrasound in diagnosing isthmocele. This may lead to surgical correction and prevention of obstetric and perinatal complications in subsequent pregnancies, including Cesarean scar pregnancy. Regarding threats, the existence of different surgical techniques means that there is a risk of selecting an inadequate approach if the type of isthmocele and the patient's characteristics are not considered. There is a risk of overtreatment when asymptomatic defects are repaired surgically. Finally, there is an absence of cost-effectiveness analyses to justify routine repair. Thus, while there are many data suggesting that isthmocele has an adverse effect on both natural fertility and the outcome of assisted reproduction techniques, high-quality evidence to support surgical isthmocele repair in all asymptomatic patients desiring future fertility are lacking. There is increasing agreement to recommend hysteroscopic repair of isthmocele as a first-line approach as long as the residual myometrial thickness is at least 2.5-3.0 mm. © 2023 The Authors.

Abstract
INTRODUCTION The reported incidence of parapneumonic pleural effusion, including empyema, has shown fluctuations in the last decades. It has been related to the implementation of different types of conjugate pneumococcal vaccines. METHODS We have retrospectively reviewed data from all 10 public hospitals in Alicante Province (Spain) covering a population of 279,000 children under 15 years of age, between 2010 and 2018. Effusions less than 10 mm (PE-) and those of 10 mm or more (PE+) were separated. RESULTS A total of 366 episodes of parapneumonic pleural effusion have been analyzed, 178 PE- (48.6%) and 188 PE+ (51.4%), with a median age of 4 years (interquartile range: 2-7 years) and marked seasonality with the maximum in winter and the minimum in summer. A culture proven bacterial agent was identified in 34 patients (9.3%), mainly Streptococcus pneumoniae (24 patients) followed by Streptococcus pyogenes (7 patients). The most frequent S. pneumoniae serotype was 19A (6 patients) and 3 vaccine failures were observed. The mean annual incidence rate was 14.3 cases per 100,000 children under 15 years of age (7.0 for PE- and 7.3 for PE+). No significant changes were observed in incidence over time, but noticeable differences in incidence were observed in different health departments. CONCLUSIONS We have not found temporal variations in incidence of parapneumonic effusion despite the implementation of the 13-valent pneumococcal conjugate vaccine. The unexplained disparity in incidence between close departments is noteworthy.

Abstract
Abstract
Study question
Are recombinant FSH biosimilars approved by the European Medicines Agency (EMA) comparable in efficacy and safety to the originator follitropin alfa?
Summary answer
Pooled analysis from studies comparing EMA-approved biosimilars with the reference product did not detect differences in efficacy or safety between these two gonadotropins.
What is known already
A biosimilar is, according to EMA, a biological medicine highly similar to another already approved (‘reference’), and are approved according to the same standards of quality, safety and efficacy. Their development and approval opens a window of opportunity to make IVF treatments more affordable for the general population. Two previous meta-analysis of phase III non-inferiority randomized controlled trials (RCT) including non EMA-approved rFSH biosimilars (Chua et al., 2021 and Budani et a., 2021) have suggested that pregnancy and live births are lower with biosimilars compared to follitropin alfa.
Study design, size, duration
Systematic review with meta-analysis following PRISMA guidelines.
Participants/materials, setting, methods
Databases searched from inception to november 2021 were: PubMed-MEDLINE, WOS, The Cochrane Library, ClinicalTrials.gov, EudraCT and Google Scholar using these keywords: ‘biosimilars’, ‘follitropin alfa’, `originator’ and ‘ovarian stimulation’. RCTs and non-randomized comparative studies were included. Risk of bias was assessed with ROB-2 tool and Newcastle-Ottawa Scale studies. Pooled Odds Ratios (OR) and mean differences (MD) when applicable, with a 95% confidence interval (CI), were calculated. PROSPERO protocol registration has been requested.
Main results and the role of chance
After the systematic search,five studies were included in the meta-analysis: two phase-III RCT (Strawitzki, 2016 and Rettenbacher, 2015) and three non-randomized comparative studies, one of them prospective (Kaplan 2021) and the other two retrospective (Sprem Goldstajn, 2021 and Van den Haute, 2021) involving 2173 IVF cycles. Risk of bias was low for the two RCT and moderate for the observational studies. The OR of clinical pregnancy was 0.89 (95% CI = 0.74,1.07; I2=0%) and the OR of live birth was 0.86 (95% CI = 0.71,1.04; I2=0%). No differences were observed in the cumulative birth rate either (OR = 0.86; 95% CI = 0.68, 1.09; I2 0%). The total number of oocytes retrieved was similar (MD = 0.25; 95%CI,-0.93, 1.43; I2 79%); as it was the total dose of gonadotropins employed (MD=-19.56; 95% CI, -57.88, 18.76; I2 0%) and the length of the stimulation (MD = 0.12; 95% CI,-0.23, 0.47; I2 80%). The risk of Ovarian Hyperstimulation Syndrome was similar in both cases (OR = 1.36; 95% CI, 0.63, 2.91; I2 21%).
Limitations, reasons for caution
Main limitations of this meta-analysis include the fact that three of the five included studies are not randomized studies and two of them are retrospective, which can bias the results.
Wider implications of the findings
This is the first meta-analysis including only results from studies with biosimilars EMA-approved. The results show that there are no differences between the biosimilars and the reference in terms of efficacy or safety. Larger RCTs including patients with different patterns of ovarian response are needed to confirm these findings.

Abstract
Abstract
Study question
Is there an optimum progesterone threshold level below which gestational results are significantly worse in frozen embryo transfer cycles (FET) with hormone replacement therapy (HRT)?
Summary answer
Low serum progesterone during luteal phase of HRT-FET cycles impairs substantially its gestational outcomes, regardless of threshold level, origin of oocytes and euploidy of embryos.
What is known already
HRT for endometrial preparation in FET or oocyte donation cycles is widely used. Oestrogen doses are usually patient-tailored varying upon endometrial thickness, whereas the optimal level of progesterone exposure has not been defined. Various studies have found a negative association between serum progesterone levels measured during luteal phase and FET results in terms of pregnancy and miscarriage rates. Most likely there is an optimal level below which results are worse but a standard threshold level is yet to be established, as in almost every study a different threshold has been found.
Study design, size, duration
Systematic review and stratified meta-analysis with meta-regression following PRISMA guidelines. An electronic search of MEDLINE, EMBASE, Web of Science, Cochrane Gynaecology and Fertility Specialised Register of Controlled Trials and ClinicalTrials.gov was conducted from inception to January 2021. The aim was to identify prospective or retrospective cohort studies measuring serum progesterone levels around frozen embryo transfer date in HRT cycles. A combination of the following key search terms was used: “progesterone”, “serum”, “frozen embryo”, “transfer”, “frozen-thawed”.
Participants/materials, setting, methods
Studies analyzing association of luteal serum progesterone with FET-HRT outcomes were included. Risk of bias within studies was assessed using the Newcastle-Ottawa Scale (NOS). Clinical/ongoing pregnancy and miscarriage rates (C/OPR,MR) were considered as primary and secondary outcomes respectively. Odds Ratios with 95% Confidence Interval (OR,95%CI) were calculated applying a random effects model meta-analysis. Heterogeneity was assessed using the I2 statistic. A meta-regression was conducted to examine the association of the effect with the threshold level.
Main results and the role of chance
The systematic search retrieved 792 studies, 494 after duplicates removal of which 343 were screened and 51 assessed for eligibility. 12 studies, reporting 14 threshold levels, were included in the meta-analysis involving 5009 HRT-FET cycles. Two of them were prospective cohort studies while the rest were retrospective. 10 of them have been published in peer review journals and two were conference abstracts. Quality of studies assessed with NOS varied between 5 and 9. The progesterone threshold ranged from 5.0 to 21.94 ng/ml. Low progesterone levels were associated with less C/OPR (OR: 0.52; 95% CI: 0.40 to 0.66; 11 studies, 5009 cycles). Low progesterone was also associated with high MR (OR: 2.01; 95% CI: 1.57 to 2.58; 9 studies, 2560 pregnancies). These effects showed remarkable consistency in specific sub-analyses considering separately studies with progesterone thresholds up to or above 10 mg/mL, and studies carried out in cycles using oocyte donation, autologous oocytes and embryo aneuploidies screening. Meta-regression did not identify significant association between size effect and progesterone threshold, regarding neither C/OPR (regression coefficient: 0.02; CI 95%: –0.02 to 0.06; p: 0.28) nor MR (regression coefficient: 0.11; CI 95%: –0.13 to 0.36; p: 0.32).
Limitations, reasons for caution
High degree of clinical and statistical heterogeneity was found due to different routes and doses of progesterone administration, date of progesterone analyses and variety of thresholds as well as high diversity of embryo origin. Despite sensibility analysis by embryo origin any of these sources of heterogeneity can preclude the results.
Wider implications of the findings: Despite low progesterone levels are significantly associated to lower gestational results, and a threshold of 10 ng/ml constitutes the median value of our distribution, high quality prospective studies are needed to validate the prognostic value of progesterone levels and to establish an standardised threshold level for clinical application.

Abstract
BACKGROUND Persistent inflammation and immune activation are associated with lymph node fibrosis and end-organ diseases in treatment-suppressed people living with HIV (PLWH). We investigated the effect of switching to raltegravir and/or adding losartan on lymphoid tissue fibrosis and on the inflammatory/immune-activation mediators in treated HIV patients. METHODS Chronic HIV-infected patients treated with two nucleoside reverse transcriptase inhibitors (2NRTI) and one non-NRTI (NNRTI) or protease inhibitor (PI) during at least 48 weeks were randomized to four groups (n = 48): 2NRTI + efavirenz (EFV), 2NRTI + EFV + losartan, 2NRTI + raltegravir and 2NRTI + raltegravir + losartan for 48 weeks. Tonsillar biopsy and peripheral blood markers of CD4 and CD8 T-lymphocyte activation and senescence, monocyte activation and soluble markers of inflammation were determined at baseline and at week 48 and compared between groups. RESULTS No changes in lymphoid tissue architecture were observed. Adding losartan had no impact on lymphocyte subsets. Conversely, patients who switched to raltegravir showed a higher decrease in all activated [CD4+CD38+HLA-DR+, -0.3 vs. 0.48 (P = 0.033); CD8+CD38+ HLA-DR+, -1.6 vs. 1.3 (P = 0.02)] and senescent [CD4+CD28-CD57+, -0.3 vs. 0.26 (P = 0.04); CD8+CD28-CD57+, -6.1 vs. 3.8 (P = 0.002)] T lymphocytes. In addition, the median CD4/CD8 ratio increased by 0.35 in patients in the raltegravir group vs. 0.03 in the other arms (P = 0.002). Differences between groups in monocyte subpopulations or soluble inflammation markers were not observed. CONCLUSIONS Losartan had no effect on lymphoid fibrosis or immune activation/inflammation. Conversely, switching to a regimen with raltegravir significantly decreased activated and senescent T-lymphocyte subpopulations and increased CD4/CD8 ratio in successfully treated PLWH.

Abstract
Introduction: The most appropriate treatment for parapneumonic effusion (PPE), including empyema, is controversial. We analyzed the experience of our center and the hospitals in its reference area after adopting a more conservative approach that reduced the use of chest tube pleural drainage (CTPD). Methods: Review of the clinical documentation of all PPE patients in nine hospitals from 2010 to 2018. Results: A total of 318 episodes of PPE were reviewed; 157 had a thickness of <10 mm. The remaining 161 were 10 mm or thicker and were subdivided into three increasing sizes: PE+1, PE+2, and PE+3. There was a strong relationship between the size of the effusion and complicated effusion/empyema, defined by its appearance on imaging studies or by the physical or bacteriological characteristics of the pleural fluid. The size of effusion was also strongly related to the duration of fever and intravenous treatment and was the best independent predictor of the length of hospital stay (LHS) (p < 0.001). CTPD was placed in 2.9% of PE+1 patients, 19.3% of PE+2, and 63.9% of PE+3 (p < 0.001). The referral of patients with PE+1 decreased over time (p = 0.033), as did the use of CTPD in the combined PE+1/PE+2 group (p = 0.018), without affecting LHS (p = 0.814). There were no changes in the use of CTPD in the PE+3 group (p = 0.721). Conclusions: The size of the PPE is strongly correlated with its severity and with LHS. Most patients can be treated with antibiotics alone.

Abstract
Se evaluó la morfometría de pezuñas en bovinos criados en los humedales del Ñeembucú y áreas de influencia. Participaron 80 hembras adultas agrupadas por genotipos en Criollo Ñeembucú; Criollo Pilcomayo; Nelore; Brahman y Brangus, analizándose Longitud muralla (LM); Altura pezuña (AP); Longitud talón (LT); Longitud pezuña (LP); Diagonal pezuña (DP); Grosor pezuña (GP). El análisis con el software R incluyó varianza paramétrica y no paramétrica, y en las pezuñas anterior medial y posterior lateral, Análisis de Componentes Principales, Discriminante Canónico y Clúster por el método de Ward. El Criollo Ñeembucú mostró mayores LM y AP, el Nelore las menores; la LT, reveló estabilidad longitudinal en nativos, no así en el Nelore. La LP fue mayor en Criollos, Nelore y Brangus. La DP mostró adecuado reparto de las cargas. El GP, mayor en el Nelore y Brangus, fue menor en el Brahman, con talones bajos y menores DP y LP. El ACP explicó más del 70% de la variación. El CP1 se asoció positivamente a DP, LP, LM, LT y AP; el CP2 fue vinculado a GP. El ADC explicó mejor la variabilidad entre genotipos, con valores elevados de GP en el Nelore y bajos en el Brahman. El método de Ward conformó grupos con la mayoría de los genotipos, revelando poca diferencia entre individuos; no obstante, algunos clústeres concentraron en grupos diferentes a la mayoría de los animales Nelore y Brahman.

Abstract
Hepatic perivascular epithelioid cell tumors (PEComas) are uncommon mesenchymal neoplasms. PEComas concurrent with other hepatic lesions is a very rare occurrence, with only two previously reported cases. We report a primary hepatic PEComa associated with focal nodular hyperplasia in a patient with a previous history of cutaneous melanoma. Diagnostic imaging studies suggested a hepatic adenoma and the patient underwent a segmentectomy. The tumor was mainly composed of epithelioid cells, adipose tissue and smooth muscle fibers intermixed with blood vessels. The neoplastic cells were diffusely immunoreactive for HMB-45, Melan-A and smooth muscle actin, but not for Hepatocyte, S100, MITF or BRAF. Molecular studies were negative for BRAFV600 mutation. The final diagnosis was hepatic epithelioid angiomyolipoma/PEComa. The differential diagnosis of hepatic PEComa is discussed.

Abstract
The world's highest levels of surface ultraviolet (UV) irradiance have been measured in the Atacama Desert. This area is characterized by its high altitude, prevalent cloudless conditions, and a relatively low total ozone column. In this paper, we provide estimates of the surface UV (monthly UV index at noon and annual doses of UV-B and UV-A) for all sky conditions in the Atacama Desert. We found that the UV index at noon during the austral summer is expected to be greater than 11 in the whole desert. The annual UV-B (UV-A) doses were found to range from about 3.5 kWh/m2 (130 kWh/m2) in coastal areas to 5 kWh/m2 (160 kWh/m2) on the Andean plateau. Our results confirm significant interhemispherical differences. Typical annual UV-B doses in the Atacama Desert are about 40% greater than typical annual UV-B doses in northern Africa. Mostly due to seasonal changes in the ozone, the differences between the Atacama Desert and northern Africa are expected to be about 60% in the case of peak UV-B levels (i.e. the UV-B irradiances at noon close to the summer solstice in each hemisphere). Interhemispherical differences in the UV-A are significantly lower since the effect of the ozone in this part of the spectrum is minor.

Abstract
The Atacama Desert has been pointed out as one of the places on earth where the highest surface irradiance may occur. This area is characterized by its high altitude, prevalent cloudless conditions and relatively low columns of ozone and water vapor. Aimed at the characterization of the solar spectrum in the Atacama Desert, we carried out in February-March 2015 ground-based measurements of the spectral irradiance (from the ultraviolet to the near infrared) at seven locations that ranged from the city of Antofagasta (on the southern pacific coastline) to the Chajnantor Plateau (5,100 m altitude). Our spectral measurements allowed us to retrieve the total ozone column, the precipitable water, and the aerosol properties at each location. We found that changes in these parameters, as well as the shorter optical path length at high-altitude locations, lead to significant increases in the surface irradiance with the altitude. Our measurements show that, in the range 0–5100 m altitude, surface irradiance increases with the altitude by about 27% in the infrared range, 6% in the visible range, and 20% in the ultraviolet range. Spectral measurements carried out at the Izaña Observatory (Tenerife, Spain), in Hannover (Germany) and in Santiago (Chile), were used for further comparisons.

Abstract
The aim of this study was to analyse the eventual changes in health-related quality of life (HRQoL) and left ventricular function (LVF) over a 1-year follow-up period in a cohort of patients with lower risk myelodysplastic syndromes (MDS) receiving standard supportive treatment, in order to identify potential clues for early clinical intervention, as well as to analyse how they relate to haemoglobin levels and other aspects of the disease. A total of 39 adult anaemic patients with lower risk MDS were included in a prospective, observational, multi-centre study. Changes in performance status, functional capacity and HRQoL were collected by using standardised measures (ECOG scale; SPPB, Short Physical Performance Battery; SF-36, Short-Form 36 questionnaire; QLQ-C30, Quality of Life Core Questionnaire; FACT-An, Functional Assessment of Cancer Therapy-Anaemia scale questionnaires respectively). Need for transfusion (Linear Analogue Scale Assessment), as perceived independently by the patient and the haematologist, was also recorded. No changes in HRQoL (or LVF) were found, except for slight reductions in SF-36 physical function (P = 0.034), SPPB gait speed (P = 0.038) and FACT-An score (P = 0.029), all without apparent immediate clinical relevance for HRQoL, that were unrelated to changes in haemoglobin level. Periodical evaluation of gait speed may assist the clinician in early detection of patient's occult functional decline before it becomes clinically relevant.

Abstract
BACKGROUND Sharka is caused by Plum pox virus (PPV) in stone fruit trees. In orchards, the virus is transmitted by aphids and by grafting. In Arabidopsis, PPV is transferred by mechanical inoculation, by biolistics and by agroinoculation with infectious cDNA clones. Partial resistance to PPV has been observed in the Cvi-1 and Col-0 Arabidopsis accessions and is characterized by a tendency to escape systemic infection. Indeed, only one third of the plants are infected following inoculation, in comparison with the susceptible Ler accession. RESULTS Genetic analysis showed this partial resistance to be monogenic or digenic depending on the allelic configuration and recessive. It is detected when inoculating mechanically but is overcome when using biolistic or agroinoculation. A genome-wide association analysis was performed using multiparental lines and 147 Arabidopsis accessions. It identified a major genomic region, rpv1. Fine mapping led to the positioning of rpv1 to a 200 kb interval on the long arm of chromosome 1. A candidate gene approach identified the chloroplast phosphoglycerate kinase (cPGK2) as a potential gene underlying the resistance. A virus-induced gene silencing strategy was used to knock-down cPGK2 expression, resulting in drastically reduced PPV accumulation. CONCLUSION These results indicate that rpv1 resistance to PPV carried by the Cvi-1 and Col-0 accessions is linked to allelic variations at the Arabidopsis cPGK2 locus, leading to incomplete, compatible interaction with the virus.

Abstract
Background: Mucoepidermoid carcinoma (MEC) shows differences in biological behaviour depending mainly on its histological grade. High-grade tumours usually have an aggressive biological course and they require additional oncological treatment after surgery. Methods: In a series of 43 MECs of the salivary glands, we studied the epidermal growth factor receptor (EGFR) gene by using dual-colour chromogenic in situ hybridisation (CISH). Moreover, we assessed the protein expressions of the EGFR and the activated extracellular signal-regulated kinases (pERK1/2) by using immunohistochemistry. These results were correlated with the histological grade of the tumours and the outcome of the patients. Results: The CISH study demonstrated a high-EGFR gene copy number, with balanced chromosome 7 polysomy, in 8 out of 11 high-grade MECs (72.7%), whereas 27 low-grade and 15 intermediate-grade tumours had a normal EGFR gene copy number (P<0.001). The EGFR gene gains correlated with disease-free interval (P=0.003) and overall survival of the patients (P=0.019). The EGFR protein expression had a significant correlation with the histological grade of the tumours but not with the outcome of the patients. The pERK1/2 expression correlated with histological grade of tumours (P<0.001), disease-free interval (P=0.004) and overall survival (P=0.001). Conclusions: The EGFR/ERK pathway is activated in high-grade MECs with aggressive behaviour. Patients with these tumours who require oncological treatment in addition to surgery could benefit from EGFR and mitogen-activated protein kinase pathway inhibitors.

Abstract
e17058 Background: With the new indications of chemotherapy or cetuximab in HNSC, the rate of pts receiving these therapies nowadays is unclear. Methods: This retrospective study identified all consecutive pts with HNSC from January 1, 2006, to December 31, 2007, presented in a multidisciplinary team to decide further treatment in a single institution. ASCO guidelines for larynx preservation were followed to select surgery or chemoradiotherapy (ChRt). We classified the intention-to-treat as palliative, adjuvant or induction therapy. In the last case, always with concomitant radiotherapy (Rt) or prior to concomitant ChRt. Cetuximab was indicated with Rt as induction therapy for pts with problems to receive platin-based chemotherapy. Results: : A total of 350 pts were identified, 320 were male (91%), and 30 female (9%), with mean age 60.4 (range 41–90). Primary tumor was located in glottis (41%), supraglottis (19%), hypopharynx (11%), oropharynx (20%), or mouth (9%). Staging was I (27%), II (22%), III (16%), or IV (35%). Surgery alone was performed in 136 pts (39%) and chemotherapy or cetuximab in 214 other pts (61%). The intention-to-treat was palliative in 69 (32%), adjuvant in 51 (24%), or induction 94(44%) of the pts respectively. Rt plus cetuximab was administered to 31/97 (33%) and Rt plus chemotherapy in 63/97 (67%) pts as induction therapy. During this 2-year period, some pts received both induction/adjuvant and palliative chemotherapy. Conclusions: Chemotherapy or cetuximab is indicated as part of treatment in more than a half of pts with HNSC. Induction therapy is the most frequent indication. No significant financial relationships to disclose.

Abstract
INTRODUCTION This work has aimed to evaluate the prevalence of patent foramen ovale in subjects with migraine with aura by transcranial contrast doppler and to describe the clinical and risk profile of these patients. METHOD We performed a transcranial contrast doppler in 94 consecutive out-patients with migraine with aura (MWA) in a neurology outpatient clinic. They were divided into two groups according to the presence of patent foramen ovale: MWA_RLsh (with right-to-left shunt) and MWA_RLNsh (without right-to-left shunt). Differences between the groups were analyzed according to endpoints of age, gender, clinical severity, aura type and attacks frequency, comorbility, cardiovascular risk factors (CVRFs), neuroimaging findings, severity of shunt and treatment. RESULTS n=94; MWA_RLsh: 47 (54%). MWA_RLNsh: 40 (46%). Age: 33.13; standard desviation (SD): 10.8 vs 33.496; SD: 11.2; p=0.728. Female: 66 vs 72.5%; p=0.511. Visual aura: 73.9% vs 78.9%; p=0.921. There were no significant differences in regards to the risk factors studied or to the comorbid diseases that are associated to migraine. The patients with patent foramen ovale have an odds ratio (OR) of ischemic stroke: 1.189 (95% confidence interval [CI]: 0.226 to 6.248; p=0.840), OR for subclinical brain lesions in cranial magnetic resonance imaging (MRI): 0.589 (95% CI: 0.193 to 1.799; p=0.35) and OR for combined previous ischemic stroke and subclinical brain lesions: 0.745 (95% CI: 0.261 to 2.129; p=0.58). Migraine attack frequency >1 per month: 27.9 vs 36.4; p=0.464. Need for prophylaxis therapy: 44.7 vs 57.7%; p=0.284. CONCLUSIONS Both groups are similar regarding their clinical profile. We did not find a greater prevalence of stroke or silent brain lesions in the group with positive shunt..

Abstract
INTRODUCTION The aim of this study is to compare the diagnosis, management, clinical course and outcome of the very major patients with acute stroke in our sanitary area. METHOD Retrospective collection of data from a hospital-based registry, between January 2002 and March 2004, 130 stroke patients aged 84 and older admitted consecutively. We compared the patients admitted to the neurology unit (NU) to those admitted to other services (GWs). Demographic analysis, risk factors, morbidity to hospital admission (dementia, cancer, previous stroke and laboratory variables), neurological deficit measured for Canadian Neurological Scale (CNS) score, diagnostic studies, length of stay, outcomes variables (in-hospital mortality, complications developed during hospitalization and Rankin scale at hospital discharge) and need for institutionalization were analyzed. RESULTS from a total of 130 patients, 44 (34,1 %) admitted to NU and 85 (65,9 %) to GWs. No difference was seen in demographic analysis, risk factors, morbidity to hospital admission, neurological deficit and outcomes variables. Length of stay was 8,4 days; 5,5 in the NU and 12,87 days among patients in the GWs (p=0,0001). There are significant differences in diagnostic studies in favor to NU (p < 0,05). Among the patients admitted into GWs the percentage of institutionalization to the discharge was of 28,8 % opposite to 5,6 % in the NU (p=0,006). CONCLUSIONS There are not evidences of age discrimination for access to neurological units for demographic, risk factors, morbidity or neurological deficit. The diagnostic process is more rigorous and less costly in the NU than in the GWs.

Abstract
Histological affected or close margin is an adverse factor in conventional surgery of larynx-hypopharynx cancer. Our objective was to analyze the relevance of the margins in transoral laser microsurgery (TLM). A retrospective study of 357 consecutive patients with cancer of the larynx and hypopharynx (T1-T4) treated with TLM. Three possible margins were considered: tumor free, affected, and uncertain. An affected margin showed marked tumor infiltration. An uncertain margin was defined when the sample was insufficient, when it showed carbonization impeding accurate evaluation, or when tumor cells were less than 2 mm. Margins were free in 254 (71.1%) patients, affected in 64 (17.9%) and uncertain in 39 (10.9%). One hundred and three patients (28.9%) presented tumor relapse. The margins were associated with tumor relapse (P < 0.001), but were not significantly related to the tumor site (P = 0.307), the pT classification (P = 0.183), or the difficulty of surgical exposure (P = 0.427). Distant metastases were found in 4.7% of the patients with free margins, in 7.7% of those with uncertain margins, and in 14.1% with affected margins. These differences were statistically significant (P = 0.028). Tumor involvement of the surgical margin was associated with higher rates of local relapse, distant metastasis and the necessity of salvage surgery, together with a lower specific actuarial survival rate.

Abstract
AIMS Adenosquamous carcinoma (ASC) of the head and neck is an unusual neoplasm in which a general consensus with regard to diagnostic criteria has not yet been reached. In this study we report the clinicopathological results of 12 ASCs, with special attention to their histological and immunohistochemical characteristics in order to define this neoplasm more precisely. METHODS AND RESULTS All the patients were male with a peak incidence in the sixth decade of life. The tumours were located most frequently in the larynx and oral cavity, followed by the nasal cavity and pharynx. ASCs had two distinct histological components. The most extensive one was an usual keratinizing squamous cell carcinoma, arising from the surface epithelium, where characteristically severe dysplasia or carcinoma in situ was found in all cases. The second component was an adenocarcinoma, usually displayed in the deepest areas of the tumour. Evidence of origin from salivary or seromucinous glands was not found. Immunohistochemical studies demonstrated in most cases positivity of glandular differentiated areas for carcinoembryonic antigen (CEA) (11/12), CK7 (9/12) and CAM5.2 (7/12), whereas the squamous cell component was unreactive or reacted only focally for these markers. High-molecular-weight cytokeratin 34BE12 was positive in both components and CK20 was always negative. All cases showed high expression of Ki67 antigen. Most of them had overexpression of p53 (8/12) and DNA aneuploidy (10/12). Fifty percent of patients with ASC died of disease after a mean period of 23 months (range 12-35 months). CONCLUSIONS ASC of the head and neck is an aggressive neoplasm that originates in the surface epithelium of the upper respiratory tract. Severe dysplasia or carcinoma in situ is usually found and its recognition helps to make the diagnosis. In addition to mucin stains, positive immunoreactivity for CEA, CK7 and CAM5.2 helps to identify the glandular component.

Abstract
We present a new family of pupil masks to control the axial component of the intensity distribution in the focal region of tightly focused light fields. The filters, which consist of a circular clear pupil with a single shaded ring, allow to control the width of the central lobe of the axial spot together with the residual sidelobes energy. The filters can be applied to improve the optical sectioning capacity of different scanning microscopes.

Abstract
INTRODUCTION Hydrocephalus, cerebrospinal fluid (CSF) leak, pseudomeningocele and CSF infection are potential complications related to surgical treatment of posterior fossa tumors. The objectives of this study were to review the incidence of such complications and to identify contributing factors related to them. MATERIAL AND METHODS This study is based on a retrospective review of the medical records of 71 consecutive patients who underwent posterior fossa surgery for a tumor between the period January 1997 and December 2001. Postoperative hydrocephalus was defined as enlargement of the ventricles and the subsequent clinical worsening requiring surgical treatment. Criteria for CSF leakage were:observed leak of CSF through the wound, rhinorrhea or otorrhea. Pseudomeningocele was determined when there was a large epidural CSF collection diagnosed in the postoperative period or by magnetic resonance imaging performed at least three months after posterior fossa surgery. Finally, CSF infection was defined on clinical ground and positive biochemical examination, but not necessarily positive cultures. RESULTS The series included 84 operations for resection of posterior fossa tumors on 71 patients. There were CSF related complications in 31% (26/84)with the following detailed incidence: 9.5% (8/84) postoperative hydrocephalus; 14.3% (12/84) CSF leak, 7.1% (6/84) pseudomeningocele; 8.3% (7/84) CSF infection. The mortality rate is 5.9% (5/84). The tumor size was the only statistically significant factor associated with the occurrence of CSF related complications (mean 39.43 mm, SD 18.51 mm vs.29.80 mm, SD 14.12 mm, p=0.015). In the subgroup of patients, in which hydrocephalus was managed preoperatively, the election of an external ventricular drain vs.other strategies (subcutaneous reservoir, definite shunt or endoscopic third ventriculostomy) was associated with a higher occurrence of CSF related complications (p=0.006). The mortality rate was associated with age (mean 63.60 years, SD 5.86 years vs.49.18 years, SD 16.39 years; p=0.002). The occurrence of CSF related complications also influenced mortality (p=0.030), particularly postoperative hydrocephalus (p< 0.001). Inpatient hospital stay was longer in the subgroup of patients who developed CSF related complications (p=0.002). CONCLUSIONS Tumor size was the only factor associated with the development of CSF related complications after surgery for posterior fossa tumors. In the subgroup of patients in which hydrocephalus was surgically treated preoperatively, the election of an external ventricular drain compared to other surgical modalities was associated with a higher rate of CSF related complications. The development of such complications, particularly hydrocephalus, was related with mortality.

Abstract
OBJECTIVE The results obtained with therapy of intracranial aneurysms, in terms of morbidity and mortality, are very important when the patient has to choose between microsurgical techniques or endovascular management. The aim of this paper is to review the information regarding current microsurgical treatment of intracranial aneurysms, and presenting our experience over the last five years. MATERIAL AND METHODS We studied 101 consecutive patients with 121 intracranial aneurysms admitted between 1996 and 2000 with the initial diagnosis of subarachnoid hemorrhage. We paid special attention to the day of admission from the onset of the symptomatic hemorrhage to the grade of Hunt&Hess scale and the possibility of early or delayed microsurgical treatment. The diagnosis was based on four vessels cerebral angiography and in a few cases with CT-angiography. All patients were treated by microsurgical technique and such treatment was completed by nimodipine, intensive care unit management and in some cases of postoperative suspected vasospasm, induced arterial hypertension was applied. Post surgical angiography was carried out in all patients to confirm the clipping of the cerebral aneurysm. The 12 months assessment was based on the Glasgow Outcome Scale (GOS). RESULTS The 92.1% of the patients were admitted with a grade equal or below III in the Hunt&Hess scale. A 80% were operated within the 72 hours of admission and in the remaining cases, the surgical treatment was delayed due to a grade IV or V or to a medical contraindication. Four patients died (3.9%). At 12 months follow up, 88.9% presented a score I or II in the GOS. CONCLUSION According to our results, there are a substantial improvements in the microsurgical treatment of cerebral aneurysms, specially in patients admitted early after the onset of the symptoms of their hemorrhage, who have a grade I to III in the Hunt&Hess scale and showed a good level of consciousness. We think that the improvement of our results are due to: l. the high percentage of patients admitted with grades I to III. 2. the high percentage of patients operated within the first 72 hours from the onset of their symptomatic hemorrhage. 3. surgery was always carried out by the same two experienced vascular neurosurgeons. 4. intraoperative measures taken to prevent the rupture of the aneurysm. 5. early administration of nimodipine, ICU management, doppler studies and in seldom cases, induced hypertension therapy to treat the vasospasm and postoperative hypotension.

Abstract
In this article, the sensorineural hearing loss is presented as a possible sequelae of neonatal hyperbilirubinemia. In our program of early hipoacusia detection, 241 babies were examined from January 1996 until November 1999; 7 cases had a history of hyperbilirubinemia in the neonatal period and 2 of them were diagnosed of sensorineural hearing loss. We discuss how the bilirubin or any other associated factor might have been the cause and this could explain the selective affectation of some children.

Abstract
A novel procedure for shaping the axial component of the point spread function of nonparaxial focusing systems by use of phase-only pupil filters is presented. The procedure is based on the Toraldo technique for tailoring focused fields. The resulting pupil filters consist of a number of concentric annular zones with constant real transmittance. The number of zones and their widths can be adapted according to the shape requirements. Our method is applied to design filters that produce axial superresolution in confocal scanning systems.

Abstract
Susceptibility to two-stage skin carcinogenesis in the mouse is affected by several genes. In addition, studies suggest that genes that modify the response of mice to skin tumor promotion by 12-O-tetradecanoylphorbol-13-acetate (TPA) also may influence histologic changes in the skin as the result of TPA treatment. One TPA susceptibility locus, Psl1, previously was mapped to distal chromosome 9. The mapping of this locus was confirmed by marker-based genotypic selection. Furthermore, Psl1 or a gene closely linked to Psl1 influenced epidermal hyperplasia and epidermal labeling index of mice treated with TPA.
