Abstract
INTRODUCTION The management of patients with prostate cancer (PCa) is established in clinical practice guidelines, which are based on randomized studies according to the level of evidence. In Spain, the degree of compliance with these guidelines in clinical practice is unknown. OBJECTIVES To describe the profiles of PCa patients at the time of diagnosis and the management of patients with localized PCa and those with BCR in Spain. MATERIALS & METHODS A medical survey was conducted in specialized care (85 urologists [UROs], 64 radiation oncologists [ROs], and 21 medical oncologists [MOs]). Three questionnaires were developed for this study with 22 (UROs and ROs) or 21 questions (MOs). RESULTS The annual incidence of PCa was 24,057 in participating hospitals (N = 131). The extrapolated annual incidence in Spain is 40,531 cases. The estimated prevalence of PCa in Spain is 221,689. Of note, 79% and 80% of patients seen by UROs and ROs, respectively had localized PCa at diagnosis. Biopsy was the most used diagnostic test among the three specialties, followed by abdominopelvic computer tomography. More than 90% of patients with BCR underwent standard tests. Next generation imaging tests and PET-choline/PSMA are still used residually. Most patients with localized PCa are currently treated with either surgery or radiotherapy, while for BCR patients, UROs and ROs prefer radiotherapy and MOs androgen deprivation therapy alone or in combination. CONCLUSION This study describes patient profiles at the time of diagnosis and provides an overview of the current therapeutic management of localized PCa and BCR in clinical practice in Spain.

Abstract
INTRODUCTION Amino acid PET is a tool recommended by the main neuroimaging societies in the differential diagnosis between radionecrosis (RNC) and umour recurrence (TR) in brain tumours, but its use in our country is still limited. The aim of this work is to present our experience with 6-[18F]FDOPA PET/CT (FDOPA) in brain tumours (primary and M1), comparing these results with other published results. MATERIAL AND METHODS Retrospective study of 62 patients with suspected tumour recurrence (TR): 42 brain metastases (M1) and 20 primary, who underwent FDOPA. Images were analysed visually and semi-quantitatively, obtaining SUVmax and SUVmaxlesion/SUVmaxstriatum (L/S) and SUVmaxlesion/SUVmaxcortex (L/C) ratios. The diagnostic validity of PET was analysed and the best performing cut-off points were calculated. PET results were compared with clinical-radiological follow-up and/or histopathology. RESULTS TR was identified in 49% of M1 and 76% of brain primaries. The best performing FDOPA interpretation was visual and semi-quantitative, with a sensitivity and specificity in primaries of 94% and 80% and in M1s of 96% and 72% respectively. The cut-off points with the best diagnostic performance were L/C1.44 in M1 and L/C1.55 in primaries. There are discrepant results with other published results. CONCLUSION FDOPA PET/CT is a useful tool in the differential diagnosis between recurrence and RNC in brain tumours. It is needed a standardization to contribute to homogenise FDOPA results a inter-centre level.

Abstract
Bipolar disorders (BD) are characterized by cognitive impairment during the euthymic phase, to which treatments can contribute. The anticholinergic properties of medications, i.e., the ability of a treatment to inhibit cholinergic receptors, are associated with cognitive impairment in elderly patients and people with schizophrenia but this association has not been well characterized in individuals with remitted BD. Moreover, the validity of only one anticholinergic burden scale designed to assess the anticholinergic load of medications has been tested in BD. In a literature review, we identified 31 existing scales. We first measured the associations between 27 out of the 31 scales and objective cognitive impairment in bivariable regressions. We then adjusted the bivariable models with covariates: the scales significantly associated with cognitive impairment in bivariable and multiple logistic regressions were defined as having good concurrent validity to assess cognitive impairment. In a sample of 2,031 individuals with euthymic BD evaluated with a neuropsychological battery, two scales had good concurrent validity to assess cognitive impairment, whereas chlorpromazine equivalents, lorazepam equivalents, the number of antipsychotics, or the number of treatments had not. Finally, similar analyses with subjective anticholinergic side-effects as outcome variables reported 14 scales with good concurrent validity to assess self-reported peripheral anticholinergic side-effects and 13 to assess self-reported central anticholinergic side-effects. Thus, we identified valid scales to monitor the anticholinergic burden in BD, which may be useful in estimating iatrogenic cognitive impairment in studies investigating cognition in BD.

Abstract
Lymphomas of the CNS are the second most frequent primary brain malignancy in adults after gliomas. Presurgical suspicion of lymphoma greatly impacts patient management. The radiologic features of this tumor have been widely covered in the literature for decades, but under current classifications, mainly corresponding to the most common presentations of the most frequent type: primary diffuse large B-cell lymphoma of the CNS. Nevertheless, rarer presentations of this specific lymphoma and of other World Health Organization lymphoma subtypes with different imaging features are rarely treated. Moreover, important advances in imaging techniques, changing epidemiologic factors with relevant impact on these tumors (eg, immunodeficiency/dysregulation), and recent updates of the World Health Organization Classification of CNS Tumors 2021 and Hematolymphoid Tumors 2022 may have rendered some accepted concepts outdated. In this article, the authors aim to fulfill a critical need by providing a complete update-review, emphasizing the latest clinical-radiologic features of the full spectrum of lymphomas involving the CNS.

Abstract
BACKGROUND AND PURPOSE Immunodeficiency-associated CNS lymphoma may occur in different clinical scenarios beyond AIDS. This subtype of CNS lymphoma is diffuse large B-cell and Epstein-Barr virus-positive. Its accurate presurgical diagnosis is often unfeasible because it appears as ring-enhancing lesions mimicking glioblastoma or metastasis. In this article, we describe clinicoradiologic features and test the performance of DSC-PWI metrics for presurgical identification. MATERIALS AND METHODS Patients without AIDS with histologically confirmed diffuse large B-cell Epstein-Barr virus-positive primary CNS lymphoma (December 2010 to January 2022) and diagnostic MR imaging without onco-specific treatment were retrospectively studied. Clinical, demographic, and conventional imaging data were reviewed. Previously published DSC-PWI time-intensity curve analysis methodology, to presurgically identify primary CNS lymphoma, was used in this particular lymphoma subtype and compared with a prior cohort of 33 patients with Epstein-Barr virus-negative CNS lymphoma, 35 with glioblastoma, and 36 with metastasis data. Normalized curves were analyzed and compared on a point-by-point basis, and previously published classifiers were tested. The standard percentage of signal recovery and CBV values were also evaluated. RESULTS Seven patients with Epstein-Barr virus-positive primary CNS lymphoma were included in the study. DSC-PWI normalized time-intensity curve analysis performed the best for presurgical identification of Epstein-Barr virus-positive CNS lymphoma (area under the receiver operating characteristic curve of 0.984 for glioblastoma and 0.898 for metastasis), followed by the percentage of signal recovery (0.833 and 0.873) and CBV (0.855 and 0.687). CONCLUSIONS When a necrotic tumor is found in a potentially immunocompromised host, neuroradiologists should consider Epstein-Barr virus-positive CNS lymphoma. DSC-PWI could be very useful for presurgical characterization, with especially strong performance of normalized time-intensity curves.

Abstract
BACKGROUND AND PURPOSE DSC-PWI has demonstrated promising results in the presurgical diagnosis of brain tumors. While most studies analyze specific parameters derived from time-intensity curves, very few have directly analyzed the whole curves. The aims of this study were the following: 1) to design a new method of postprocessing time-intensity curves, which renders normalized curves, and 2) to test its feasibility and performance on the diagnosis of primary central nervous system lymphoma. MATERIALS AND METHODS Diagnostic MR imaging of patients with histologically confirmed primary central nervous system lymphoma were retrospectively reviewed. Correlative cases of glioblastoma, anaplastic astrocytoma, metastasis, and meningioma, matched by date and number, were retrieved for comparison. Time-intensity curves of enhancing tumor and normal-appearing white matter were obtained for each case. Enhancing tumor curves were normalized relative to normal-appearing white matter. We performed pair-wise comparisons for primary central nervous system lymphoma against the other tumor type. The best discriminatory time points of the curves were obtained through a stepwise selection. Logistic binary regression was applied to obtain prediction models. The generated algorithms were applied in a test subset. RESULTS A total of 233 patients were included in the study: 47 primary central nervous system lymphomas, 48 glioblastomas, 39 anaplastic astrocytomas, 49 metastases, and 50 meningiomas. The classifiers satisfactorily performed all bilateral comparisons in the test subset (primary central nervous system lymphoma versus glioblastoma, area under the curve = 0.96 and accuracy = 93%; versus anaplastic astrocytoma, 0.83 and 71%; versus metastases, 0.95 and 93%; versus meningioma, 0.93 and 96%). CONCLUSIONS The proposed method for DSC-PWI time-intensity curve normalization renders comparable curves beyond technical and patient variability. Normalized time-intensity curves performed satisfactorily for the presurgical identification of primary central nervous system lymphoma.

Abstract
INTRODUCTION To assess the management of immunocompetent patients with primary central nervous system lymphomas (PCNSL) in Spain. METHODS Retrospective analysis of 327 immunocompetent patients with histologically confirmed PCNSL diagnosed between 2005 and 2014 in 27 Spanish hospitals. RESULTS Median age was 64 years (range: 19-84; 33% ≥ 70 years), 54% were men, and 59% had a performance status (PS) ≥ 2 at diagnosis. Median delay to diagnosis was 47 days (IQR 24-81). Diagnostic delay > 47 days was associated with PS ≥ 2 (OR 1.99; 95% CI 1.13-3.50; p = 0.016) and treatment with corticosteroids (OR 2.47; 95% CI 1.14-5.40; p = 0.023), and it did not improve over the years. Patients treated with corticosteroids (62%) had a higher risk of additional biopsies (11.7% vs 4.0%, p = 0.04) but corticosteroids withdrawal before surgery did not reduce this risk and increased the diagnostic delay (64 vs 40 days, p = 0.04). Median overall survival (OS) was 8.9 months [95% CI 5.9-11.7] for the whole series, including 52 (16%) patients that were not treated, and 14.1 months (95%CI 7.7-20.5) for the 240 (73.4%) patients that received high-dose methotrexate (HD-MTX)-based chemotherapy. Median OS was shorter in patients ≥ 70 years (4.1 vs. 13.4 months; p < 0.0001). Multivariate analysis identified age ≥ 65 years, PS ≥ 2, no treatment, and cognitive/psychiatric symptoms at diagnosis as independent predictors of short survival. CONCLUSIONS Corticosteroids withdrawal before surgery does not decrease the risk of a negative biopsy but delays diagnosis. In this community-based study, only 73.4% of patients could receive HD-MTX-based chemotherapy and OS remains poor, particularly in elderly patients ≥ 70 years.

Abstract
Abstract
BACKGROUND
Radiation-induced necrosis (RDN) is a side effect observed in patients who underwent stereotactic radiosurgery (SRS) alone or combined with whole brain radiotherapy (WBRT) as treatment for their brain tumors. Nowadays, RDN diagnosis and differentiation from tumor progression using the standard imaging techniques represents a challenge, and histological diagnosis still is the gold standard.Our aim is to assess the positive and negative predictive values (PPV, NPV) of FDG-PET and perfusion magnetic resonance imaging (MRI) in RDN diagnosis.
MATERIAL AND METHODS
From our Pathology department database, all patients with RDN or mixed (tumor plus RDN) brain lesions diagnosis during last 5 years were reviewed. Demographic, clinical and oncologic treatment characteristics were recorded. MRI and FDG-PET images at the suspicion (clinical or radiological) of progression or RDN were registered and compared with the definite diagnosis provided by the tissue sample analysis. Sensitivity, specificity, as such as PPV and NPV for perfusion MRI sequences and FDG-PET image analysis were calculated.
RESULTS
162 patients underwent SRS+/- WBRT in a 5 year period. During follow-up, 11 patients had surgery-confirmed RDN. There are 11 patients (3 women) with 12 lesions, 3 from a breast cancer, 6 from a lung tumor, 1 from a melanoma, 1 atypical meningioma and 1 glioblastoma. 9 of them were treated with both SRS and WBRT, and the 3 others with WBRT alone. The mean age was 65.36 (range: 44–77) years. The median time between the completion of radiation therapy and the suspicion of RDN was 19.7 (range: 3–34) months. With the evolution, it was observed an evident increase in the size of surronding oedema (2–6 times) by FLAIR RMI. We estimate a PPV 0.40 and NPV 0.80 for perfusion MRI, and PPV 0.25 and NPV 0.75 for FDG-PET, respectively.
CONCLUSION
The diagnostic performance of both techniques in our series is low and similar to published data; therefore its results must be carefully interpreted in each case. It is peremptory to implement new diagnostic tools in the standard of care with better diagnostic outcomes.

Abstract
Molecular epidemiological studies revealed that the epicenter of the HIV pandemic was Kinshasa, the capital city of the Democratic Republic of the Congo (DRC) in Central Africa. All known subtypes and numerous complex recombinant strains co-circulate in the DRC. Moreover, high intra-subtype diversity has been also documented. During two previous surveys on HIV-1 antiretroviral drug resistance in the DRC, we identified two divergent subtype C lineages in the protease and partial reverse transcriptase gene regions. We sequenced eight near full-length genomes and classified them using bootscanning and likelihood-based phylogenetic analyses. Four strains are more closely related to subtype C although within the range of inter sub-subtype distances. However, these strains also have small unclassified fragments and thus were named CRF92_C2U. Another strain is a unique recombinant of CRF92_C2U with an additional small unclassified fragment and a small divergent subtype A fragment. The three remaining strains represent a complex mosaic named CRF93_cpx. CRF93_cpx have two fragments of divergent subtype C sequences, which are not conventional subtype C nor the above described C2, and multiple divergent subtype A-like fragments. We then inferred the time-scaled evolutionary history of subtype C following a Bayesian approach and a partitioned analysis using major genomic regions. CRF92_C2U and CRF93_cpx had the most recent common ancestor with conventional subtype C around 1932 and 1928, respectively. A Bayesian demographic reconstruction corroborated that the subtype C transition to a faster phase of exponential growth occurred during the 1950s. Our analysis showed considerable differences between the newly discovered early-divergent strains and the conventional subtype C and therefore suggested that this virus has been diverging in humans for several decades before the HIV/M diversity boom in the 1950s.

Abstract
During development of the nigrostriatal dopamine system, a patchy and a diffuse type of striatal innervation pattern can be seen. It has been suggested that when fetal dopaminergic neurons, obtained from the ventral mesencephalon (VM), are grafted adjacent to mature striatal tissue, only the diffuse growth is induced. Intraocular grafting studies have indicated that the dopaminergic growth pattern might be influenced by the age of the target area, the lateral ganglionic eminence (LGE). In this study VM grafts were allowed to innervate LGE grafts of different ages. Fetal VM was implanted next to 2-wk-old or 26-day-old striatal in oculo grafts, and the resulting dopaminergic innervation of the striatal grafts was studied using tyrosine hydroxylase (TH) immunohistochemistry. In striatal grafts receiving innervation at the age of 2 wk in oculo, a patchy TH-immunoreactive growth pattern was found, while in striatal grafts innervated at the age of 26 days mainly the diffuse growth pattern was seen. This implies that grafted striatum reached maturity at approximately 1 mo of age. The age of the dopaminergic neurons at dissection and grafting was also studied concerning the ability to induce patchy growth into mature striatum. Thus, VM dissected from 13- and 18-mm fetuses was implanted to either 4-mo-old LGE (grafted in sequence) or to LGE from the same fetus (grafted simultaneously) as controls. TH-positive innervation of striatal tissue, evaluated 4 wk after implantation of VM, revealed a patchy growth pattern in LGE grafted simultaneously with 13- and 18-mm VM. However, when the striatum was mature at the time of innervation, diffuse growth was observed in striatum innervated by VM dissected from 13-mm fetuses. Interestingly, patchy growth was noted in striatal areas close to VM grafts when the dopaminergic neurons were derived from older fetuses (CRL 18 mm). Furthermore, potassium-induced dopamine release was greater in striatal grafts exhibiting the patchy growth than those showing the diffuse pattern of innervation. In conclusion, patchy dopaminergic growth can be induced in mature striatal tissue by grafting VM from older fetuses. Functionally, potassium-evoked dopamine release is enhanced in dopaminergic patches. These results have implications in terms of finding ways to induce patchy growth when grafting to the mature striatum of patients suffering from Parkinson's disease.

Abstract
Many carbonyl species from either lipid peroxidation or glycoxidation are extremely reactive and can disrupt the function of proteins and enzymes. 4-hydroxynonenal and methylglyoxal are the most abundant and toxic lipid-derived reactive carbonyl species. The presence of these toxics leads to carbonyl stress and cause a significant amount of macromolecular damages in several diseases. Much evidence indicates trapping of reactive carbonyl intermediates may be a useful strategy for inhibiting or decreasing carbonyl stress-associated pathologies. There is no rapid and convenient analytical method available for the assessment of direct carbonyl scavenging capacity, and a very limited number of carbonyl scavengers have been identified to date, their therapeutic potential being highlighted only recently. In this context, we have developed a new and rapid sensitive fluorimetric method for the assessment of reactive carbonyl scavengers without involvement glycoxidation systems. Efficacy of various thiol- and non-thiol-carbonyl scavenger pharmacophores was tested both using this screening assay adapted to 96-well microplates and in cultured cells. The scavenging effects on the formation of Advanced Glycation End-product of Bovine Serum Albumin formed with methylglyoxal, 4-hydroxynonenal and glucose-glycated as molecular models were also examined. Low molecular mass thiols with an α-amino-β-mercaptoethane structure showed the highest degree of inhibitory activity toward both α,β-unsaturated aldehydes and dicarbonyls. Cysteine and cysteamine have the best scavenging ability toward methylglyoxal. WR-1065 which is currently approved for clinical use as a protective agent against radiation and renal toxicity was identified as the best inhibitor of 4-hydroxynonenal. We describe a rapid method for assessment of reactive carbonyl scavengers. We evaluated the carbonyl scavenger activity of various pharmacophores. α-amino-β-mercaptoethane structure showed the highest degree of activity.

Abstract
INTRODUCTION Bifocal fractures of the mandible often associate the angle and condyle or symphysis. Little data is available on biangular fractures. The authors had for aim to study their characteristics and to suggest an adapted management. MATERIAL AND METHODS We retrospectively reviewed the records of patients operated on for a biangular fracture from January 2005 to December 2009. The impact of a third molar was evaluated using Pell and Gregory's and Shiller's classifications. RESULTS Six hundred and forty patients underwent surgery for a mandibular fracture, seven of whom (1.1%) for biangular fractures. The patients' mean age was 27.6 years. Patients were predominantly men (85.7%). Assaults or brawls were the most frequent etiology (85.7%). The mechanism was direct impact in every case. The inferior alveolar nerve was injured in 57.1% of cases. There was an impacted third molar in 71.4% of cases. Most of the time, a single miniplate was sufficient for each angle. Two cases of postoperative infection were noted. The mean follow-up was 52.2months. The occlusion was restored in every case. Three patients presented with neurological sequels in the V3 area. DISCUSSION Biangular fractures are rare and present a high risk of infection and neurological sequels. The presence of a mesioangular impacted third molar seems to be a predisposing factor. The risk of neurological sequels requires performing surgery rapidly.

Abstract
We reported, in previous experiments, that AA is a global regulator of cAMP pools. In this study, we demonstrate that K873, an analog of AA we synthesized and presenting antiproliferative properties, has also an impact on cAMP production. However, K873 has no antioxidant activity, at the contrary of AA. It definitively demonstrates that action of AA on the cAMP production is not linked to antioxidant activity. These data suggest that AA, and derivatives of this molecule, could be promising drug acting on biological processes that are under the control of cAMP dependent pathway.

Abstract
A protocol was developed for genetic transformation of somatic embryos derived from juvenile and mature Quercus robur trees. Optimal transformation conditions were evaluated on the basis of the results of transient GUS expression assays with five oak embryogenic lines and a strain of Agrobacterium tumefaciens (EHA105) harbouring a p35SGUSINT plasmid containing a nptII and a uidA (GUS) genes. For stable transformation, embryo clumps at globular/torpedo stages (4-10 mg) were inoculated with EHA105:p35SGUSINT bacterial cultures, cocultivated for 4 days and selected in proliferation medium with 75 mg/l of kanamycin. Putatively transformed masses appeared after 20-30 weeks of serial transfers to selective medium. Histochemical and molecular analysis (PCR and Southern blot) confirmed the presence of nptII and uidA genes in the plant genomes. Transformation efficiencies ranged from up to 2% in an embryogenic line derived from a 300-year-old tree, to 6% in a juvenile genotype. Twelve independent transgenic lines were obtained from these oak genotypes, and transgenic plantlets were recovered and acclimatized into the soil. This is the first demonstration of the production of transformed somatic embryos and regenerated plants from juvenile and mature trees of Q. robur and suggests the possibility of introducing other genetic constructions to develop trees that are tolerant/resistant to pathogens and/or biotic stresses.

Abstract
A procedure for inducing somatic embryos in shoot apex explants (2 mm) excised from shoot proliferation cultures established from adult oak trees (Quercus robur) was investigated. Embryogenesis was induced in shoot tip as well as leaf explants in three out of the five genotypes evaluated. Somatic embryos were formed by culture in induction medium supplemented with 21.48 muM naphthalene acetic acid and 2.22 muM benzyladenine for 8 weeks, and successive transfer of explants to expression media with a low concentration of growth regulators and without them. Both types of explants formed callus tissue from which somatic embryos developed, indicating indirect embryogenesis. Although the embryogenic frequencies were lower than 12%, it did not prevent the establishment of clonal embryogenic lines maintained by repetitive embryogenesis. Histological study confirmed an indirect somatic embryogenesis process from shoot tip explants, in which leaf primordia and the corresponding axial zones were involved in generating callus, whereas the apical meristem itself did not proliferate. The origin of embryogenic cells appeared to be associated with dedifferentiation of certain parenchymal cells in callus regions after transfer of explants to expression media without auxin. Division of embryogenic cells gave rise to proembryo aggregates of unicellular origin, although a multicellular origin from bulging embryogenic areas would also seem possible. Further development led to the formation of cotyledonary-stage somatic embryos and nodular embryogenic structures that may be considered as anomalous embryos with no clear bipolarity. Inducement of somatic embryos from explants isolated from shoot cultures ensures plant material all year round, thus providing a significant advantage over the use of leaf explants from field-grown trees.

Abstract
The aneurysmal bone cyst is a rare, expansive, osteolytic, pseudocystic lesion with an unknown etiology. It usually affects long bones and the spine. Two to 5 % of cases have mandibular localization (between 75 and 100 % present on the mandible) accounting for 1 % of all mandibular cysts. Less than 200 cases have been reported in English and French literature.

Abstract
We studied some biochemical, toxic and immunological characteristics of the venoms of Bothrops atrox, Bothrops brazili and Lachesis muta, Viperidae responsible for most of the bites of venomous snakes in French Guiana. Chromatographic (HPLC) and electrophoretical profiles (SDS-PAGE), lethal, hemorrhagic, defibrinogenating, coagulant, thrombin like, proteolytic, fibrino(geno)lytic and phospholipase activities were studied. In addition, the neutralization of some toxic activities conferred by four antivenins was compared. The chromatographic and electrophoretic profiles were different for the three venoms, showing differences between Bothrops and L. muta venoms. In general, bothropic venoms showed the highest toxic and enzymatic activities, while the venom of L. muta showed the lowest lethal, hemorrhagic and coagulant activities. The enzymes of bothropic venoms responsible for gelatinolytic activity were around 50-90 kDa. All the venoms were able to hydrolyze a and beta chains of the fibrinogen, showing different patterns of degradation. Although all the antivenoms tested were effective to various degrees in neutralizing the venom of B. brazili and B. atrox, neutralization of L. muta venom was significantly better achieved using the antivenom including this venom in its immunogenic mixture. For the neutralization of L. muta venom, homologous or polyvalent antivenoms that include the "bushmaster" venom in their immunogenic mixture should be preferred.

This study reports on the cryostorage of embryogenic lines derived from selected mature Quercus robur trees, following application of the PVS2-vitrification based procedure. In seven oak genotypes, embryo recovery levels ranging from 57-92% were obtained when 4-6 mg embryo clumps were precultured for 3 days on 0.3 M sucrose basal medium, treated with PVS2 solution for 60 min at 24 degrees C, and then immersed in liquid nitrogen (LN). Embryos of six out of seven lines were cryostored for one week and one year and used to evaluate cryopreservation tolerance, germination ability and to assess genetic fidelity by random amplified polymorphic DNA (RAPD) markers. There were no significant differences between the recovery frequencies of samples retrieved from LN after 1 week and 1 year of cryostorage. In five out of six lines, RAPD profiles of cryopreserved somatic embryos and regenerated plantlets were identical to those of the controls. Although polymorphisms were detected in only one cryostored embryo of one genotype, no genetic instability was found in the regenerated plantlets. This methodology appears to be suitable for long-term storage of this valuable germplasm, as the recovered plantlets were found to be genetically stable.

Abstract
Since 1990 when the first series on substaging were published, they have published numerous publications on the invasion sublevel of high degree T1 carcinomas. The deep invasion entails a high risk of progression (around 30-35% of cases progress) as opposed to the cases of superficial invasion over "muscularis mucosae", in which the progression is around 10%, reason why most authors consider subT1, in patient management. In this revision the more exhaustive series that have evaluated substaging are shown and also the different methods to carry out this staging considering the inherent difficulty to the samples that come from transurethral resection (RTU).

Abstract
INTRODUCTION Facial reconstruction technique can be simple or complicated. The choice of performing a flap is made according to several criteria. Since its first description the submental flap has been used in several indications. The aim of this article was to document maxillofacial surgeons on this flap technique. ANATOMY The submental artery is a major branch of the facial artery. This artery runs medial to the mandible and ends next to the mandibular symphysis. The submental artery supplies the submandibular lymph nodes, submandibular salivary gland, mylohyoid and digastric muscles, and the skin of the chin. The submental vein drains the tissues of the chin as well as the submandibular region. TECHNIQUE The integrity of the facial artery is a sine qua none condition before performing this flap. It is important that the submandibular gland and the submental vessels be well exposed. The anterior belly of the homolateral digastric muscle must be included in the flap. The donor side is closed after a large subcutaneous dissection of the neck and chin. INDICATIONS The pedicled submental flap is indicated in defects of the oral cavity and the lower two-thirds of the face. ADVANTAGES The submental flap is relatively easy to raise. This flap avoids dyschromia and provides soft-tissues presenting with the same quality as that of the tissue surrounding the defect. Sequels on the donor side are minor. DISADVANTAGES The submental flap is not indicated if a submental neck dissection is needed or in case of intraoral/frontal reconstruction with bearded skin. The submental flap is a simple and reliable procedure, with good aesthetics results and minor sequels.

Abstract
INTRODUCTION The technique used for reconstruction of a cervicofacial defect depends on the extent of the tissue loss. Locoregional or free flaps are commonly used for this type of reconstruction. The type of flap used depends on donor site availability and morbidity. The aim of this technical note was to present appropriate use of the fascia temporalis flap in maxillofacial surgery. ANATOMIC BASIS: The superficial fascia temporalis lies just under the scalp. Blood is supplied via the superficial temporal artery which widely irrigates this anatomic region. Venous blood is drained by the superficial temporal vein and the posterior auricular vein. SURGICAL TECHNIQUE First, the skin flap is drawn after determining the required size and length of the vascular pedicle. The T or Y incision enables complete exposure of the superficial fascia temporalis and the temporal vessels. The superficial fascia temporalis fascia is then resected at the desired size and easily dissected from the deep temporal fascia via the avascular plane. This dissection is easily achieved manually using a compress. INDICATIONS This flap can be used in the auricular region, for commissural reconstruction to ensure facial motricity, for eyelids defects, for defects in the frontal or zygomatic area and for defects of the palate or labial or cheek mucosa. ADVANTAGES This flap can be raised rapidly and easily without any specific requierment. The flap is reliable and allows a long pedicle. The superficial fascia temporalis is thin and easily remodeled. The scar at the donor site is masked by the hair. DRAWBACKS: This flap may not be available in the event of previous trauma or surgery with a high risk of injury to the temporal vessels. This flap is not suitable in patients with prior irradiation exposure or malformatve disease (Franceschetti's syndrome, hemifacial atrophy etc.). Facial palsy due to facial nerve injury, sensorial disorders or local alopecia can develop post-operatively. For reconstruction of the lower third of the face, other flaps should be preferred.
