Abstract
Since a few years, the transoral robotic surgery reduced the morbidity of oropharyngeal tumors excision. Large posterior tumors can now be removed without any scar visible on the face. In this context and to respect the thinness required for reconstructions at the junction of the upper aerodigestive tract, the free radial forearm flap still remains the solution of choice. However, if the transoral robotic surgery respects the anatomy and the aesthetics of patients at the visible and social area that represents the face, the forearm flap provides visible scars on the other region of social interaction that represents the upper limb. The aim of our work was to prove the feasibility and the benefits in terms of reducing sequelae when using a thin anterolateral perforator flap harvested above the plane of the superficial fascia. We present this new original method in detail and the advantages it offers to patients after surgery.

Abstract
e20019 Background: The number of agents active in patients with metastatic melanoma is limited and cure is not an objective for treatment at this stage, so that clinical benefit in these patients is the most important. The aim of the study was to evaluate the efficacy and safety of combination regimen consisting of paclitaxel and carboplatin as second-line chemotherapy, in patients with MM. Based on reports of responses to PC, 17 patients with MM was treated at the National Cancer Institute of Mexico. Methods: We evaluated retrospectively the combination of PC in patients with MM. Data regarding patient characteristics and outcomes were abstracted from medical records of NCI of Mexico from 01/05 to 12/08. The regimen was weekly paclitaxel (at a dose of 80 mg/m2) received on days 1, 8, and 15 of a 21-day cycle and carboplatin (AUC 5) on day 1. Response evaluation was using RECIST and toxicity was according to National Cancer Institute Common Toxicity Criteria. This study was approved by the hospital ethics committee. Results: Seventeen patients with MM were treated with PC. All patients were previously treated (and failed) with dacarbazine (DTIC). Sixteen were assessable for response with three cycles of chemotherapy and seventeen for toxicity. One patient was deemed to be ineligible because they presented severe hypersensitivity reaction to paclitaxel at beginning. Objective partial response were obtained in 4 patients (25%); 8 stable disease (50%) at least four months. No patient had a complete response to therapy. Progression disease was in 4 patients (25%). In 12 (75%) we noted clinical benefit. The median time to disease progression for the entire group was 4.2 months (range, 1–11 mos), with a median overall survival of 8.1 months (range, 5.6–10.5 mos). The toxicity grade 3 reported was thrombocytopenic in 2 patients (11%) and anemia in one patient (6%). Additional patients had reversible toxicities grade 3 including alopecia, nausea and fatigue; 2 of them presented moderate hypersensitivity reactions to paclitaxel. No toxic death was noted. Conclusions: The PC combination appears to be safety and well tolerated in second line chemotherapy in MM, however we need more patients to demonstrate a true clinical benefit, we outcomes are according with other clinical reports. No significant financial relationships to disclose.

Abstract
BACKGROUND Although global studies such as the International Study of Asthma and Allergies in Childhood (ISAAC) have provided valuable data on the prevalence of asthma in children in Latin America, there is little information on the relationship between asthma symptoms, pulmonary function, bronchial hyperresponsiveness (BHR) and atopy in the region. METHODS This study examined the relationship between self-reported wheezing in the past 12 months, pulmonary function, airway responsiveness and atopy in children from a low income population in a neighbourhood of Santiago, Chile. Two random samples (100 each) of children aged 13-14 years who participated in ISAAC phase I were selected according to whether or not they reported wheezing in the past 12 months. Spirometry, the methacholine bronchial challenge test and the prick test were performed in all individuals. RESULTS Children who reported current wheezing had significantly higher BHR to methacholine compared with those without wheezing (71.6% vs 52.6%; p = 0.007) and no significant difference was found in forced expiratory volume in 1 s (116.7 (12.3)% vs 120.3 (14.5%); p = 0.11). The prevalence of atopy was not significantly different between those children who reported wheezing compared with those who did not (44.2% vs 42.3%; p = 0.89). Multiple regression analysis showed that only BHR to methacholine (OR 2.72, 95% CI 1.25 to 4.13; p = 0.01) and maternal asthma (OR 3.1, 95% CI 1.2 to 8.3, p = 0.03) were significant risk factors for current wheezing. CONCLUSIONS Our results support previous findings suggesting that in adolescents from underprivileged populations, self-reported current wheezing is related to BHR but not to atopy.

Abstract
BACKGROUND In developed countries, the prevalence of asthma in children has significantly increased in the last decades. However, there is no information about the trends of asthma in Latin America. AIM To determine changes in asthma prevalence between 1994 and 2002 in Chilean schoolchildren. MATERIAL AND METHODS The prevalence of asthma symptoms in schoolchildren aged 7 (n =18.697) and 13 years (n =18.939), from South Santiago, Valdivia and Punta Arenas, obtained during phases I and III of the ISAAC, carried out in 1994 and 2002, was compared. RESULTS From 1994 to 2002, the mean national prevalence of "wheezing in the last 12 months" in the group aged 6-7 years, changed from 18.2% to 17.9% (p =NS); "asthma ever" from 12.5% to 10.7% (p =NS), and "severe episode" from 3.2% to 2.8% (p =NS). There was a significant increase of the prevalence of "wheezing in the last 12 months", in children aged 13-14 years, from 9.8% to 15.5% (p =0.01); in "asthma ever" from 10.2% to 14.9% (p =0.01), and for "severe episode" from 2.8% to 3.8% (p =0.01). CONCLUSIONS There was a significant increase in the prevalence of respiratory symptoms related to asthma in children aged 13-14 years that was consistent in all the 3 participating centres of the ISAAC. However, the prevalence of asthma symptoms in children aged 6-7 years remained without significant changes between 1994 and 2002.

Abstract
A physicochemical sludge with high microbial content (10(2)-10(4) FPU/g TS bacteriophages, 10(6)-10(7) MPN/g TS faecal coliforms, 10(4) MPN/g TS Salmonella spp., 10(4) MPN/g TS Shigella spp., 10(3) MPN/g TS Pseudomonas aeruginosa, 10(2) MPN/g TS Vibrio cholerae, 10(2)-10(3) cysts/g TS Giardia sp., 10(2)-10(4) oocyts/g TS Cryptosporidium sp., 168-215 viable helminth ova/g TS) was disinfected using silver, silver-copper, and silver-copper plus a synergistic agent (SA). Twenty milligrams Ag/g TS inactivated 4.8 log of faecal coliforms in 1 h; however, 40 mg Ag/g TS are needed to reduce helminth ova viability from 84 to 38.4% in the same period of time. Combinations of Ag-Cu (60:600 mg Ag-Cu/g TS) and Ag-SA (60:24 mg Ag-SA/g TS) inactivated 7.8 log of faecal coliforms and around 90% of helminth ova in 60 min. To produce USEPA class A biosolids, 10:100:8 and 5:50:13.3 mg Ag-Cu-SA/gTS are needed. Bacterial regrowth was not observed for all conditions producing <1000 MPN/gTS faecal coliforms, suggesting a residual disinfection effect. Recommended doses to produce class A biosolids inactivated 2-4 log of bacteriophages, 4 log of Salmonella spp., 4 log of Shigella spp., 3 log of Pseudomonas aeruginosa, 2 log of Vibrio cholerae, 87-99.9% of Giardia sp., and 75-99.9% of Cryptosporidium sp.

Abstract
About 10% of health care professionals vaccinated against hepatitis B virus (HBV) fail to develop protective antibodies. We tested the capacity of peripheral blood lymphocytes from 121 health care professionals, including 76 non-responders, to proliferate to four HBV vaccines, examined the proliferating cells' subset, production of IFN-gamma, IL-4 and IL-10, and for 22 subjects, the cytokine production genotype. Specific proliferative responses to at least one HBV antigen were noted in 75% humoral non-responders. These cells differed from the CD4+ strongly proliferating cells of responders. Non-responders frequently displayed a genotype of high TGF-beta and intermediate IL-10 secretion. Most humoral non-responders to HBV thus develop specific cellular immune responses, eventually liable to protect them against viral infection.

Abstract
A 32-year-old male patient was admitted at our department presenting microhematuria and full nephrotic syndrome in April 1995. A percutaneous kidney biopsy showed a stage I-lI membranous nephropathy and an eight-week course with oral prednisone was initiated without response. Then, oral cyclosporine A (3.5 mg/kg/day) was given and after 5 weeks of treatment, remission of the nephrotic syndrome was observed but creatinine raised to 1.6 mg/dl, normalizing after reducing the dose of cyclosporine A. We discuss the settings, prognostic and therapeutic alternatives for idiopathic membranous nephropathy.

Abstract
Glial glutamate receptors are likely to play a role in plasticity, learning, and memory and in a number of neuropathologies. An enhanced glutamate-dependent tyrosine phosphorylation has been detected in such processes. Using primary cultures of chick Bergmann glia cells and chick cerebellar slices, we addressed whether glial glutamate receptors can activate the nonreceptor tyrosine kinase pp125 focal adhesion kinase (pp125(FAK)). A dose- and time-dependent tyrosine phosphorylation of pp125(FAK) was found in both preparations upon glutamate treatment. This effect was mediated through alpha-amino-3-hydroxy-5-methyl-4-isoaxazolepropionate (AMPA)/kainate (KA) receptors, as shown by its inhibition by the specific antagonists 2,3-dioxo-6-nitro-1,2,3,4-tetrahydrobenzo[f]quinoxaline-7- sulfonamide (NBQX) and 6,7-dinitroquinoxaline-2,3-dione (DNQX) and the lack of effect of metabotropic agonists. FAK tyrosine phosphorylation was dependent on phosphatidylinositol 3-kinase activity. As expected, an increase in pp125(FAK) catalytic activity was found upon glutamate treatment. Immunprecipitation experiments demonstrated that FAK associates with ionotropic glutamate receptors. Taken together, these results suggest a role for glial glutamate receptors in cytoskeletal rearrengments and focal adhesion contact formation and provide new insight into the signaling transactions elicited by this neurotransmitter in glial cells.

Abstract
Specific and sensitive reverse transcription-PCR (RT-PCR) assays were developed for the detection of eastern, western, and Venezuelan equine encephalitis viruses (EEE, WEE, and VEE, respectively). Tests for specificity included all known alphavirus species. The EEE-specific RT-PCR amplified a 464-bp region of the E2 gene exclusively from 10 different EEE strains from South and North America with a sensitivity of about 3,000 RNA molecules. In a subsequent nested PCR, the specificity was confirmed by the amplification of a 262-bp fragment, increasing the sensitivity of this assay to approximately 30 RNA molecules. The RT-PCR for WEE amplified a fragment of 354 bp from as few as 2,000 RNA molecules. Babanki virus, as well as Mucambo and Pixuna viruses (VEE subtypes IIIA and IV), were also amplified. However, the latter viruses showed slightly smaller fragments of about 290 and 310 bp, respectively. A subsequent seminested PCR amplified a 195-bp fragment only from the 10 tested strains of WEE from North and South America, rendering this assay virus specific and increasing its sensitivity to approximately 20 RNA molecules. Because the 12 VEE subtypes showed too much divergence in their 26S RNA nucleotide sequences to detect all of them by the use of nondegenerate primers, this assay was confined to the medically important and closely related VEE subtypes IAB, IC, ID, IE, and II. The RT-PCR-seminested PCR combination specifically amplified 342- and 194-bp fragments of the region covering the 6K gene in VEE. The sensitivity was 20 RNA molecules for subtype IAB virus and 70 RNA molecules for subtype IE virus. In addition to the subtypes mentioned above, three of the enzootic VEE (subtypes IIIB, IIIC, and IV) showed the specific amplicon in the seminested PCR. The practicability of the latter assay was tested with human sera gathered as part of the febrile illness surveillance in the Amazon River Basin of Peru near the city of Iquitos. All of the nine tested VEE-positive sera showed the expected 194-bp amplicon of the VEE-specific RT-PCR-seminested PCR.

Abstract
A membrane form of L-glutamate decarboxylase (GAD) was identified and purified to apparent homogeneity from hog brain. The purified GAD was established as an integral membrane protein by phase-partitioning assay, charge-shift electrophoresis, and chromatography on a hydrophobic interaction column. This membrane GAD has a native molecular mass of 96 +/- 5 kDa and is a homodimer of 48 +/- 3-kDa subunits. Immunoprecipitation and immunoblotting tests revealed the presence of antibodies against this membrane GAD in sera from patients with insulin-dependent diabetes mellitus. Since this form of GAD appears to be an integral membrane protein and is presumed to have extracellular domains exposed, it seems reasonable to suggest that membrane GAD is more likely than soluble GAD to be involved in the pathogenesis of insulin-dependent diabetes and related autoimmune disorders such as stiff-man syndrome.

Abstract
1. Chromaffin cells of the toad were used to investigate the effects of total replacement of extracellular Na+ by monovalent cations or sucrose on secretion of catecholamine (CA). 2. K+, Rb+ or Cs+ in place of Na+ produced an immediate secretory response, which are dependent on extracellular Ca2+ and it was blocked by Co2+. Li+ or choline+ did not affect basal secretion. 3. Isosmotic replacement of Na+ by sucrose caused CA secretion even in the absence of external Ca2+ or in the presence of Ca-channel blockers. 4. Tetraethylammonium decreased the extent of CA release produced by either K+ or Rb+. 5. The secretagogue effect of Na+/K+, Na+/Rb+ or Na+/Cs+ replacement could be explained by a depolarization of the cell membrane, which ultimately will cause Ca2+ influx through voltage-dependent Ca-channels. However, the present results indicate that Na+ may be sufficient but not necessary for CA secretion.

Abstract
A study of long-term results (mean follow-up: 10.6 years) in 22 patients operated on for acute carotid thrombosis between 1962 and 1973 is reported. In most instances, surgery was performed at the acute phase of a massive cerebrovascular occlusion, usually more than 8 hours after onset (10 cases). Five of these patients (22%) died in the postoperative period. Eight (35%) recovered without residual disease. In six, the condition improved, while it remained unchanged or worsened in three (14%). There were ten delayed deaths, including two from a recurrent cerebrovascular episode and four from cardiac disease. The actuarial survival curve does not differ from that of patients treated conservatively, with rates being 60% at five years, 36% at ten years and 28% at thirteen years. The quality of certain postoperative results suggests that surgical indications at the acute stage of carotid occlusion be reviewed. The study of thirty series from the literature (1 046 cases) shows a 17% mortality rate, while 50% of patients recover or improve. This mortality is significantly lower in recent statistics, under 10%: this improvement may be ascribable to more rigid surgical indications (delay under 6 hours, operation in variable neurologic deficiencies, early diagnosis by the Doppler procedure, better postoperative management). The authors conclude that surgical management of acute carotid thrombosis should no longer be systematically dismissed.
