Abstract
The CGI-BPD scale is an adaptation of the Clinical Global Impression (CGI) scale designed to assess severity and post-intervention changes in patients with Borderline Personality Disorder (BPD). It contains 10 items that score the nine relevant psychopathological domains of BPD, plus an additional global score. The CGI-BPD has two formats, the CGI-BPD-S, to evaluate the present severity, and the CGIBPD- I to evaluate improvement. To establish the psychometric properties of the CGI-BPD, the test was administered to 78 BPD patients, 11 men and 67 women, within the framework of a 4-month therapeutic intervention. The modified scale showed good validity and reliability (alpha 0.85 and 0.89; CCI: 0.86 and 0.78), adequate sensitivity to change, and a two-factor structure accounting for 67.4 % of total variance. While remaining simple to administer, the CGI-BPD may correct the excessive generalisation contained in its original version and is a useful tool to evaluate severity and change in BPD patients.

Abstract
16009 Background: According to prescribing information, pegfilgrastim should not be administered within 14 days prior to, or within 24 hours after, the administration of cytotoxic CT. However, little data exist to support this recommendation. The purpose of the current study is to determine the safety and efficacy of administering pegfilgrastim on the same day as myelosuppressive CT in patients with ovarian or primary peritoneal carcinoma. Methods: A retrospective review was conducted of all ovarian and primary peritoneal cancer patients that received prophylactic pegfilgrastim on the same day as CT from May 2003 to June 2006. Results: Forty-six patients (mean age: 57, range: 21–82) were treated for the following malignancies: 35 (76%) epithelial ovarian, 6 (13%) primary peritoneal, and 5 (11.0%) ovarian germ cell or stromal cell carcinoma. Twenty-six patients (56%) had primary cancers and 20 (44 %) had recurrent disease. All patients met the ASCO or NCCN recommendations of using colony-stimulating factors for prophylaxis against febrile neutropenia (FN) (Risk of FN > 20%). A total of 269 cycles of CT were administered including 125 cycles (46.5%) docetaxel + carboplatin, 39 cycles (14.5%) gemcitabine + platinum, 30 cycles (11.1%) intravenous paclitaxel + carboplatin, 28 cycles (10.4%) liposomal doxorubicin, 19 cycles (7.1%) paclitaxel + intraperitoneal platinum, 6 cycles (2.2%) docetaxel, 6 cycles (2.2%) liposomal doxorubicin + cisplatin, 5 cycles (2%) bleomycin + etoposide + cisplatin, 4 cycles (1.5%) topotecan, 3 cycles (1.1%) of paclitaxel, 2 cycles (0.7%) vincristine + actinomycin-D + cyclophosphamide, and 2 cycles (0.7%) docetaxel + gemcitabine. All patients received pegfilgrastim within one hour of the completion of CT administration. Grade 1 or 2 neutropenia developed in 10 cycles (3.7%) out of the 269 cycles, mean absolute neutrophil count = 4926 (range, 1293 -24300). No patients had FN episodes, hospitalizations or antibiotic use secondary to neutropenia, or dose-reductions and CT delays due to neutropenia. Conclusions: Administration of pegfilgrastim on the same day as CT in ovarian and primary peritoneal cancer patients is more convenient to the patient and appears safe and effective. No significant financial relationships to disclose.

Abstract
Few therapeutic options are available for mucocutaneous leishmaniasis (MCL). We conducted a randomized open trial to evaluate the efficacy, safety, and tolerance of parenteral aminosidine sulphate (AS) 14 mg/kg/d for 21 days compared with intravenous meglumine antimonate (MA) 20 mg/kg/d for 28 days in patients with moderate MCL in Cuzco, Peru. Cure was defined as complete healing with re-epithelialization within 1 year of follow-up. The trial was stopped after 38 patients were enrolled (17 in the MA group and 21 in the AS group) because of marked differences in response. Study groups were comparable in baseline characteristics. Cure rates were 0/21 in the AS group compared with 8/17 (47%, 95% confidence interval: 23-71%) in the MA group (P < 0.001). Side effects and laboratory abnormalities were mild in both groups. We conclude that parenteral AS given on its own is not effective for MCL in Peru.

Abstract
Coagulation proteases are involved in a highly orchestrated proteolytic cascade which is essential for haemostasis and blood clotting. In particular, the initiator of the coagulation cascade, Factor VIIa, binds to its cofactor, tissue factor, and its substrate, Factor X, via exosite interactions to form a ternary catalytic complex named extrinsic Xase. These exosite interactions have also been shown to allosterically induce the active conformation of the catalytic site of Factor VIIa. We have developed a direct continuous fluorescence polarization-based extrinsic Xase assay, which has been used to screen in excess of 1 million structurally diverse low-molecular-mass compounds as a potential starting point for the development of anticoagulants. The primary screen hits were categorized with deconvolution assays into either active-site or exosite inhibitors. The latter category of hits displayed both competitive and uncompetitive modalities of inhibition with respect to Factor X activation. An uncompetitive mechanism of action is of particular interest as it offers a hypothetical inhibitory advantage in the context of inhibiting a proteolytic cascade such as the blood coagulation pathway.

Abstract
Microarray technology has remarkably accelerated the understanding of the molecular events of neoplasias. By means of gene expression profiles, a molecular subclassification of cancer patients and the identification of thousand of genes involved in this pathology have been achieved. Herein, the general use of DNA microarrays in cervical cancer tumorigenesis is reviewed. Finally, putative molecular tumour markers as useful factors in diagnosis, prognosis, and tailor-made therapy for this disease are proposed.

Abstract
OBJECTIVE To evaluate the safety and tolerability of long-term treatment with olanzapine versus risperidone in schizophrenic outpatients with prominent negative symptoms. METHODS This was a multi-center, randomised, open-label, parallel, dose-flexible, 1 year study of outpatients with schizophrenia (DSM-IV criteria) with prominent negative symptoms (SANS Global score > or =10). Safety was evaluated by recording treatment-emergent adverse events, vital signs, body weight and, when available, laboratory parameters. Extrapyramidal symptoms (EPS) were evaluated by a questionnaire based on the UKU scale, and sexual dysfunction by the Psychotropic-Related Sexual Dysfunction Questionnaire (PRSexDQ). RESULTS The mean (+/- SD) modal dose throughout the study was 12.3 (+/- 6.3) mg/day for olanzapine and 5.2 (+/- 2.5) mg/day for risperidone. EPS were significantly more frequent in the risperidone-treated patients 50.4 % versus 28.9 % for olanzapine (p = 0.0006). Olanzapine patients showed significantly greater reductions (improvement) from baseline in the PRSexDQ score (p=0.0292) and risperidone patients reported significantly more sexual adverse events (21.1% versus 7.3% for olanzapine; p=0.0018). Mean body weight gain was not significantly different at endpoint (3.5 kg gained with olanzapine versus 1.9 kg gained with risperidone; p=0.3522), but the proportion of patients showing a body weight increase > or =7% was higher among the olanzapine-treated patients (37.8% versus 16.8%; p=0.0012). CONCLUSIONS Significantly less treatment-emergent extrapyramidal and sexual adverse events were observed in patients treated with olanzapine compared to those treated with risperidone. Mean body weight increases with both drugs were not significantly different after one year. Olanzapine patients presented a significantly higher incidence of clinically important body weight increase when compared with patients treated with risperidone.

Abstract
INTRODUCTION This study was conducted to determine effectiveness and safety of olanzapine in patients with severe agitation. METHOD A naturalistic, open-label study in 80 acutely agitated psychotic patients visited in our psychiatric emergency department. Patients received either a 20-mg olanzapine orally-disintegrating tablet or conventional treatment depending on attending psychiatrist's preference. Efficacy was assessed by the Excitement Component of the Positive and Negative Syndrome Scale (PANSS-EC), the Agitation-Calmness Evaluation Scale (ACES) and pragmatic variables (second pharmacological intervention and need for physical restraints). RESULTS 60 % patients completed a 6 hour trial. Both groups showed a significant reduction in mean PANSS-EC score. The olanzapine-treated group showed statistically significant improvements: PANSS-EC (F=122.9; df=2.4; p=0.000), ACES (F=68.2; df=2.8; p=0.000). Treatment was well-tolerated and no serious side-effects were observed. CONCLUSIONS In this naturalistic study in patients with severe agitation, 20-mg oral olanzapine was effective, rapid and safe.

Abstract
To obtain translocations involving specific chromosomes in rye, pollen of a line in which chromosome 1R has large C-bands on its two telomeres, but which lacks C-bands (or has very small ones) on the telomeres of the remaining chromosomes, was X-irradiated. All translocations involving the labelled chromosome (1R) could be easily recognized in C-banded mitotic metaphases. The non-labelled chromosome involved in each translocation was identified either from mitotic C-banding analysis or from the meiotic configurations observed in some specific progenies. A physical map including 40 translocation breakpoints has been developed by means of synaptonemal complex (SC) analysis of well-paired pachytene quadrivalents. The results agree with the hypothesis of chromosomes 2R to 7R having similar probabilities of participating in translocations with chromosome 1R. However, the locations of the breakpoints are not entirely random: an excess of translocation breakpoints located on the short arm of chromosome 1R was obtained, and the two acentric translocated segments of each translocation show a trend towards having similar sizes. The possible reasons for these two non-random situations are discussed.

Abstract
Agitation is relatively common among Borderline Personality Disorder (BPD) patients in Psychiatric Emergency Services (PES). New injectable atypical antipsychotics are indicated for treatment in agitated psychotic or maniac patients but not for agitated BDP patients. Twenty agitated BPD patients were treated with intramuscular atypical antipsychotics (olanzapine or ziprasidone). Results suggest intramuscular atypical antipsychotics may be effective, fast and safe for treating acute BPD patients.

Abstract
INTRODUCTION Here, we describe our Tissue Banking experiences of 4 years of activity in Mexico. METHODS Data of allografts provided by our Bank and bone retrievals performed by our teams between February of 2001 and August of 2004 were included. RESULTS There were 100 bone donors, a total of 1,107 tissues were obtained with an average of 11 tissues by retrieval, samples from all tissues were obtained during retrieval and cultured for bacterial contamination, 250 tissues were positives to bacterial growth with an average of 22.58% of bacterial contamination of tissue by retrieval. A total of 4,493 allografts were provided and were utilized in 3,643 patients. The allografts were used mainly by orthopedic surgeons (62%) and dentists (30%). The most used allografts were morcellized cancellous bone 31%, pulverized 25% and chips of cancellous bone 20%. Among orthopedic patients the most frequent procedures were related with spine degenerative diseases 39.09%, followed by non-pathological fractures and its complications 28.67% and bone tumors and cystic bone lesions 11.59%. CONCLUSIONS Sustained increase of allograft utilization in Mexico reflects a great necessity for them in our country. The increase in public awareness about tissue donation has allowed an increase in tissue donations and retrievals.

Abstract
Stroke is a major health problem worldwide. Its pharmacological management includes thrombolytic therapy for the acute phase and antiplatelet drugs for stroke recovery and prevention. Statins can help in the acute phase and in preventing stroke in secondary prevention patients. Policosanol is a cholesterol-lowering drug with concomitant antiplatelet effects, with protective effects in stroke models. This observational study investigated the effects of policosanol (20 mg/day) administered during the acute phase and for 5 years later on the neurological recovery of patients with ischemic stroke treated with antiplatelets and vitamins. After hospital discharge, patients were followed up every 3 (first year) and 6 (thereafter) months. Neurological improvement was assessed with the modified Canadian Neurological Scale. Adverse events were recorded. Fifty patients were included; all completed the study. Neurological score improved throughout the study. No patient died, and most [40 (80.0%)] did not experience new vascular events; only one (2.0%) suffered a new stroke, and two (4.0%) suffered more than one transient ischemic attack. The time to the first recurrent event was 46.2 months. Policosanol persistently lowered serum total cholesterol, with such reduction correlating with the neurological improvement (R = 0.995253301). Triglycerides were unchanged. Treatment was well tolerated. Policosanol administered to patients suffering ischemic stroke treated with aspirin and vitamins showed good results on neurological outcomes and recurrent events. This study, however, has limitations, since it was open and uncontrolled, and patients also consumed aspirin and vitamins. New randomized, controlled studies are needed to assess the usefulness of policosanol in stroke management.

Abstract
INTRODUCTION Psychomotor agitation is a common event in psychiatric emergency services (PES) with a prevalence of approximately 10 %. There is no general consensus on to how to manage psychomotor agitation; benzodiazepines, typical antipsychotics and now atypical antipsychotics have demonstrated similar efficacy. The aim of our study was to describe the epidemiology and clinical management of agitation in "real-life" in a psychiatric emergency service. METHODS A naturalistic study was performed in acutely agitated patients recruited consecutively in a psychiatric emergency service. Demographics, clinical and therapeutic characteristics were analyzed. Efficacy was assessed by the Excitement Component of the Positive and Negative Syndrome Scale (PANSS-EC) and the Agitation-Calmness Evaluation Scale (ACES). Pragmatic variables such as the need for second pharmacological intervention and the need for physical restraints were assessed. RESULTS The study included 100 patients with psychomotor agitation. Mean age was 36.2 % and 54% were women. The most prevalent diagnoses were psychotic disorder (48 %) and personality disorder (24 %). Physical restraint was required in 39 % of patients and 52 % accepted oral treatment. Haloperidol was the most frequent oral treatment and olanzapine was the most frequent intramuscular treatment. CONCLUSIONS A naturalistic approach provides data based on clinical reality in psychiatric emergency services. Strict research designs of clinical trials of efficacy imply sample selection biases and are generally distanced from the clinical reality. Atypical antipsychotics have become the first-line treatment in acute agitation

Abstract
OBJECTIVE The aim of this study was to evaluate and compare the area, perimeter, and form (D factor and fractal dimension) of the dental wear among bruxist and nonbruxist children with mixed dentition in order to determine if the dental wear may be used as criteria to diagnose bruxism. METHODS The children were 8 to 11 years old and were classified as bruxist or nonbruxist, according to anxiety level and temporomandibular disorders. Dental casts of the upper arch were obtained for the bruxist (n = 24) and the control (n = 29) group. The dental wear was measured in digital format and processed automatically. The complete and pathological dental wear was compared between the two groups, using the Student's t-test and Mann-Whitney test. RESULTS Statistically significant differences were observed between the two groups, with a higher area, perimeter, and more irregular form of the pathological dental wear among the bruxist group. Regarding complete dental wear, differences were only significant for the D factor (an un-dimensional quantitative parameter which produces a relation between the area and the perimeter of an object). CONCLUSION Digital imaging of dental wear may be used as criteria to diagnose bruxism in children with mixed dentition after making an analysis of the area, perimeter, and irregularity of the form of pathological dental wear.

PATIENTS AND METHODS From 05/98 to 10/02, 114 patients were treated with preoperative chemoradiation (4500-5040 cGy + oral Tegafur 1200 mg/day) for cT(3)-(4)N(+/x)M(0) rectal cancer. Starting 05/01, 52 consecutive patients additionally received induction FOLFOX-4, oxaliplatin (85 mg/m(2) iv d1), 5-FU (400 mg/m(2) iv bolus d1) and 600 mg/m(2) iv continuous infusion in 22 h with leucovorin (200 mg iv) d1 and d2, every 15 days (2 cycles), followed by the previously described Tegafur chemoradiation regime. Surgery was performed in 5-6 weeks. Pathological assessment investigated post-treatment T and N status in the rectal wall and peri-rectal tissues. RESULTS Patients, tumor and treatment characteristics were comparable between groups. Incidence of pT(0) specimens was significantly increased by induction FOLFOX-4 (P = 0.006). Total T and N downstaging were 58% versus 75% and 42% versus 40%, respectively (P = ns). T downstaging of > or =2 categories was significantly superior in FOLFOX-4 group (P = 0.029). CONCLUSIONS Short-intense induction FOLFOX-4 significantly improves pathologic complete response in LARC patients treated with tegafur-sensitized preoperative chemoradiation. The 44% rate of pT(0)-(1) specimens observed in the oxaliplatin group should impulse innovative surgical approaches to promote ano-rectal sphincter conserving protocols.

Abstract
The majority of the neutralizing epitopes of papillomaviruses (PV) are conformation-specific and have not been fully characterised. Studies have, to date, been limited to a few HPV types only. We analysed the epitopes on the major capsid protein (L1) of Human papillomavirus (HPV) type 31 using monoclonal antibodies (MAbs) generated against HPV-31 virus-like particles (VLPs). The type-specific MAbs against HPV-31 were all found to be neutralizing and recognized conformation-dependent epitopes. Two other MAbs directed against a conformational epitope were found to be cross-reactive with other HPV types, and one of them was found to be cross-neutralizing. Cross-reactive antibodies were further investigated using wild-type HPV-16 L1 VLPs and two mutants. The results obtained suggested the existence of a cross-neutralizing conformational epitope at the N-terminal part of the FG loop of the major capsid protein, and the other four cross-reactive MAbs recognized epitopes also located at the N-terminal part of the FG loop.
