Abstract
AIMS Exposure to polycyclic aromatic hydrocarbons (PAH), among the main compounds present in polluted urban air, is of concern for children's health. Childhood exposure to PAH was assessed by urinary monitoring of 1-hydroxypyrene (1-OHP), a pyrene metabolite, investigating its association with exposure to air pollution and other factors related to PAH in air. METHODS A group of 174 4-year-old children were recruited and a questionnaire on their indoor and outdoor residential environment was completed by parents. At the same time, environmental measurements of traffic-related air pollution (NO2) were carried out. A urine sample was collected from each child in order to analyze 1-OHP using HPLC with fluorescence detection, correcting for creatinine concentrations. Non-parametric tests and regression analyses were used to identify environmental factors that influence 1-OHP excretion. RESULTS Mean urinary 1-OHP concentration was 0.061 micromol/mol creatinine, ranging from 0.004 to 0.314 micromol/mol. Non-parametric tests and regression analysis showed positive and significant associations (P<or=0.05) between 1-OHP and predicted residential exposure to NO2 (which was based on outdoor environmental measurements and geo-statistical analysis), self-reported residential vehicle traffic, passive smoking and cooking appliance. 1-OHP levels tended to be higher among children living in urban areas (0.062 micromol/mol vs. 0.058 micromol/mol for children living in rural areas) but differences were not significant (P=0.20). CONCLUSION In Southern Spain, concentrations of urinary 1-OHP were in the lower range of those generally reported for children living in non-polluted areas in Western Europe and the USA. Traffic-related air pollution, passive smoking and cooking appliance influenced urinary 1-OHP level in the children, which should be prevented due to the health consequences of the inadvertent exposure to PAH during development.

Abstract
BACKGROUND Acute esophageal necrosis has been considered a rare event. It is defined as the presence of diffuse dark pigmentation of the esophagus on upper endoscopy. Its incidence has not yet been established. The pathogenesis remains unknown. PATIENTS AND METHODS A retrospective analysis of clinical, laboratory, endoscopic, and histological data, and of the clinical course of 11 patients with acute necrotizing esophagitis was carried out over a 2-year period. RESULTS Among 3,976 patients who underwent upper endoscopy, 11 (0.28%) with acute esophageal necrosis were identified. Nutritional status was poor for 6 patients. Complete resolution of acute esophageal necrosis without further recurrence was observed in 4. One stricture appeared during follow-up and other patient developed new-onset acute esophageal necrosis. Seven patients died, but no death was directly related to acute esophageal necrosis. CONCLUSIONS The incidence of acute esophageal necrosis in our series is 0.28%. Acute esophageal necrosis is associated with high mortality rates.

Abstract
Scientists interested in contamination normally deal only with pollution itself, not with people's perceptions of pollution or the relationship between pollution and land use. The overall objective of this article was to examine the relationship between people's perceptions of pollution and their views on future land use. People were interviewed at an Earth Day Festival near the Department of Energy's Brookhaven National Laboratory (BNL) on Long Island, New York. On an open-ended question, people thought that BNL should be left as it is, or maintained as a preserve, park or conservation area, or used for environmental research. Almost no one thought that it should be used for housing or industrial purposes. When asked to rate a list of possible future land uses, maintaining BNL as a National Environmental Research Park for research and for recreation were rated the highest (nuclear storage was rated the lowest). This was consistent with the subjects' views that pollution was the greatest concern about BNL. The congruence between perceptions about concerns or problems and future land use preferences suggests a unified view of management of contaminated sites, such as BNL, at least among a group of people whose environmental interests were evident by their presence at the event.

Abstract
Threshold photoemission excited by polarization-modulated ultraviolet femtosecond laser light is exploited for phase-sensitive detection of magnetic circular dichroism (MCD) for a magnetite thin film. Magnetite (Fe(3)O(4)) shows a magnetic circular dichroism of ∼(4.5 ± 0.3) × 10(-3) for perpendicularly incident circularly polarized light and a magnetization vector switched parallel and antiparallel to the helicity vector by an external magnetic field. The asymmetry in threshold photoemission is discussed in comparison to the magneto-optical Kerr effect. The optical MCD contrast in threshold photoemission will provide a basis for future laboratory photoemission studies on magnetic surfaces.

Abstract
Renal involvement is observed frequently in association with malignant gammopathies, mainly those related to light chain deposition, although has also been described in non-malignant monoclonal gammopathy. This study reports the clinicopathological findings and outcome in 9 patients with nephropaty secondary to monoclonal immunoglobulin deposit in absence of malignancy. They were three men and six women and they were 59.2+/-12 years old. All patients presented proteinuria and different levels of renal insufficiency (mean creatinin = 315+/-187 micromol/L) at the moment of diagnostic. Two patients required dialysis at the time of renal biopsy. The pathology studies revealed a nodular sclerosing glomerulopathy in four cases, mesangiocapilary glomerulonephritis in three cases, only tubular lesions in one and mesangial lesions in the other one. The treatment applied was: Prednisone alone (two cases), with chemotherapy associated (melfalan in two, clorambucil in one and ciclophosphamide in another one). One patient received plasmapheresis and mycophenolate and another patient undergone a bone marrow authotransplant associated to mycophenolate and prednisone. One of the two patients who required dialysis at the moment of presentation was not treated. After a follow-up of more than 4 years (4.89 +/-DE: 3.69) renal function improved or remained stable in three patients and proteinuria was disappeared in more than 50% of patients. Four patients had a worsening of renal function and they required dialysis during the time of follow-up (in 2,4 years +/- DE: 4,3). In any case malignitation was observed. Chemotherapy stabilized or improved renal function in 3 of nine patients (33%) with non-malignant monoclonal gammopathy. Non-malignant monoclonal gammopathy could go unnoticed. Appearance of abnormalities in renal routine tests deserves more in-depth diagnostic procedures, including renal biopsy. Evolution to end stage renal disease could probably be avoided or reduced in severity with early detection and treatment of this entity.

Abstract
BACKGROUND The cutaneous influence areas of the different sympathetic ganglia have not been fully established to date. The aim of this study was to define the cutaneous influence area of sympathetic ganglia T2-T3. METHODS A total of 210 patients with primary hyperhidrosis (PH) underwent 420 thoracoscopic sympathicolysis procedures of ganglia T2-T3 in a prospective study. All completed a preoperative questionnaire and a second questionnaire 12 months after the operation. The questionnaires evaluated perspiration in the different body areas. Only the zones of anhidrosis were considered in delimiting the cutaneous expression of sympathetic ganglia T2-T3. RESULTS Redistribution of perspiration as reported by the patients comprised significant reduction in the palms, axillas, and soles, and an increase in the abdomen, back, and gluteal and popliteal regions. Regarding the incidence of anhidrosis by anatomical location, statistically significant changes were recorded in the head, hands, axillas, and soles (p < 0.001). CONCLUSIONS Bilateral upper thoracic sympathicolysis is followed by redistribution of body perspiration, with a clear decrease in the zones regulated by mental or emotional stimuli, and an increase in the areas regulated by environmental stimuli, though we are unable to establish the etiology of this redistribution.

Abstract
HIV prevalence is increasing among high-risk populations in the Mexican-U.S. border cities of Tijuana and Ciudad Juarez. In 2005, the molecular epidemiology of HIV-1 was studied among injecting drug users (IDU) and female sex workers (FSW) in these cities, which are corridors for over two-thirds of the migrant flow between Mexico and the United States. Eleven samples (eight IDU and three FSW) were successfully amplified, sequenced, and analyzed. The results revealed that all 11 samples were subtype B. There was no phylogenetic clustering or separation of the strains between IDU and FSW or between Tijuana and Ciudad Juarez nor was the Mexican strain phylogenetically distinct from other subtype B strains. Two of three drug naive FSWs had low-level HIV-1 resistance mutations. This community-based study demonstrated that HIV-positive IDUs and FSWs in Ciudad Juarez and Tijuana were predominantly infected with subtype B. Further prevalence studies on HIV-1 resistance mutations among FSWs in these border cities are warranted.

Abstract
Components of the cytochrome P(450) monooxygenase system (MFO) and antioxidant enzymes were investigated in the coral Montastraea faveolata exposed to the organic contaminant benzo(a)pyrene (B(a)P). For bioassays the corals were exposed to increasing concentrations of B(a)P (0.01 and 0.1 ppm) for 24 and 72 h, with water renewal every 24 h. Enzymatic activity of catalase (CAT), superoxide dismutase (SOD) and glutathione S-transferase (GST) were measured in host (polyp) and hosted (zooxanthellae) cells. NADPH cytochrome c reductase activity and contents of cytochrome P(450) and P(420) were only measured in the polyp. Antioxidant enzymes CAT and SOD in polyps and zooxanthellae and GST in polyps increased significantly at the highest concentration and maximum time of exposure. Cytochrome P(420) was found in all colonies, and the cytochrome P(450) content was greatest in the colonies from the highest concentrations of contaminant. NADPH cytochrome c reductase activity and the concentration of pigments did not vary between treatments. This is the first report of the induction of both detoxifying mechanisms, the MFO system and antioxidant enzymes on acute exposure to an organic contaminant in the reef-constructing coral species M. faveolata.

Abstract
BACKGROUND Symptomatic hypotension is the most frequent acute complication affecting patients during chronic hemodialysis treatment sessions. Many reports have demonstrated that the use of cool dialysate has a protective effect on blood pressure during hemodialysis treatments. In the present study, we investigated whether preventing the hyperthermic response had favourable effects on hemodynamic stability during the hemodialysis procedure while affording good tolerance to patients. METHODS We investigated the effect of thermal control of dialysate on hemodynamic stability in hypotension-prone patients in our center. Patients were eligible for the study if they had symptomatic hypotensive episodes (> 3/12session/ month) during the screening phase. The study was designed with two phases for the same selected patients and two treatment arms, each phase lasting 4 weeks. In the first phase, we adjusted dialysate temperature on 36 masculineC for 12 sessions (cold dialysis) and in the second phase we used a device allowing the regulation of thermal balance (Blood Temperature Monitor; Fresenius Medical Care, Bad Homberg, Germany), that keep body temperature unchanged (isothermic dialysis). RESULTS Nine HD patients were enrolled and completed the study. During the screening phase the mean ultrafiltration was 4 1% of dry weight, and blood pressure decreased from 9916 to 8016 mm Hg (p<0.001). In 5.01.7 sessions of 12 treatments were complicated by hypotension. In the first and second phase we observed a decrease of complicated treatments with symptomatic hypotension (5.01.7 versus 2.71.6 y 2.81.7; p<0.01). Both procedures: Cold dialysis and Isothermic dialysis was well tolerated by patients. CONCLUSION Results show that active control of body temperature can significantly improve intradialytic tolerance in hypotension-prone patients.

Abstract
OBJECTIVE Thoracic sympatholysis and sympathectomy are the current standard treatments for primary hyperhidrosis. In this study, we evaluated the incidence of peri- and postoperative complications associated with these procedures. PATIENTS AND METHODS From 1996 to 2004, 520 consecutive patients (364 women), with a mean age of 26.8 years, were treated for primary hyperhidrosis at our hospital. The procedure was bilateral in all but 24 cases. The 484 patients in the sympatholysis group underwent a single intervention while the 36 patients in the sympathectomy group underwent 2 separate interventions. RESULTS No deaths occurred. Anhidrosis of the target area was achieved in 97.6% of patients while 2.2% experienced hypohidrosis. In 0.2% of the cases, the procedure was initially unsuccessful and a second intervention was required. The mean duration of hospital stay was 72 hours for patients in the sympathectomy group and 17 hours for the sympatholysis group. Serious intraoperative complications requiring conversion to thoracotomy were recorded in 0.2% of patients. Postoperative complications--of which pneumothorax was the most common--occurred in 5.2% of the cases (in 22.5% of the sympathectomy group and 3.55% of the sympatholysis group). Compensatory hyperhidrosis occurred in 48.4% of the patients, excessive dryness of the hands and palpebral ptosis in 0.38%, and gustatory sweating in 0.9%. The degree of patient satisfaction was quite high (88.5%) and only 2.3% were very unsatisfied. CONCLUSIONS Given the results obtained, we can conclude that both sympatholysis and sympathectomy are appropriate treatments for hyperhidrosis. Nonetheless, because sympatholysis is both easier to perform and less aggressive, we consider it the treatment of choice for primary hyperhidrosis.

Abstract
A retrospective analysis of data from January 1996 to June 2004 was performed to evaluate the transmission of bacterial infections from organ donors to recipients. Donors were classified according to blood culture results: group 1 with negative blood culture (n = 216), and group 2 with positive blood cultures (n = 52). The age, cause of death, temperature, leukocytes, and number of organs procured were similar in both groups. Donors of group 2 had significantly more days in the intensive care unit (ICU): group 1 (3.14 +/- 3) versus group 2 (4.39 +/- 3.38 days P = .038). Fifty-one percent of group 1 and 52% of group 2 received antibiotic treatment, in most cases because of the suspected presence of a respiratory infection. In 22 donors the organisms that yielded in the blood culture were considered potentially pathogenic/contaminants (subgroup 2A) and in 30 donors the organisms were considered pathogenic (subgroup 2B). The demographic profiles of these two subgroups were similar. During the first month after transplantation, kidney and liver recipients were closely monitored. Recipients received wide-spectrum antimicrobial prophylaxis. Ten of 61 renal recipients developed infectious diseases. In nine cases (four in subgroup 2A and five in subgroup 2B) there were urinary infections. One recipient of subgroup 2B developed prostatitis. Six of 34 hepatic recipients developed infectious diseases. Four of the six cases (four in group 2A and five in group 2B) developed catheter infections and two cases of peritoneal infections. We could not find any case where a bacterial blood isolate from a donor matched a positive culture in the corresponding recipient. A longer stay of a donor in the ICU resulted in the more pronounced growth of organisms in blood cultures, as expected. In our experience, organs obtained from a donor with a positive blood culture may be transplanted safely, probably due to the low virulence of the organisms as well as the polymicrobial therapy routinely given to the recipients.

Abstract
BACKGROUND Bilateral upper thoracic sympathectomy or sympathicolysis, currently the standard treatment for palmar or axillary hyperhidrosis, is regarded as a safe procedure. This study evaluates the quantitative and qualitative incidence of intraoperative and postoperative complications resulting from bilateral thoracic sympathicolysis. METHODS From 1996 to 2004, 458 consecutive patients with primary hyperhidrosis underwent surgery. These patients comprised 143 men (31.2%) and 315 women (68.7%) with a mean age of 26 years (range, 14-52 years). In all but seven cases, the procedure was bilaterally synchronous. RESULTS No mortality was recorded. The anhydrosis rate was 97.4%, with a hypohidrosis rate of 2.4% and a failure rate of 0.2%. The latter was resolved with reintervention. The mean hospital stay was 17 h. The rate of major perioperative complications with conversion to thoracotomy was 0.4%. The overall rate of postoperative complications was 3.6%. The complications and rates observed were as follows: pneumothorax (2.06%), subcutaneous emphysema (1.08%), pleural bleeding (0.2%), hemothorax (0.1%), and atelectasis (0.1%). Compensatory hyperhidrosis was observed in 48.4% of the patients, but the sensation of compensatory hyperhidrosis was reported in 85.6% of the cases. Excessive dryness of the hands was reported in 0.38%, Horner's syndrome in 0.32%, and gustatory hyperhidrosis in 1.1% of the cases. The overall satisfaction rate was 88.5%. CONCLUSIONS The results suggest that endoscopic bilateral thoracic sympathicolysis is an effective method for managing primary hyperhidrosis, especially severe palmar hyperhidrosis, but it is necessary to inform patients fully concerning the undesirable effects.

Abstract
In medicine a considerable amount of resources are used in research, but very little attention is paid to ensuring that the findings of research are implemented in routine clinical practice. This prospective study has the aim to evaluate the efficiency of some clinical management strategies (feedback, benchmarking and improving plans) on haemodialysis treatment results in 4 different dialysis centres. We collected consensus data related to haemodialysis results every 6-8 months and informed each centre about its own results (feedback) and how these related to the others(benchmarking). We designed improving plans for any bad result detected. By the end of two years of follow up, 294 patients had been included in the study. The results obtained at the end of the study had improved in comparison with those obtained at the beginning (statistically significant) for the following indicators: % of patients with Hb< 11 g/dl, % patients with Kt/v < 1.2, mean Kt/v, mean albumin, % patients with albumin< 3.5 g/dl y % patients with C reactive protein (CRP) > 5 mg/dl. No statistical changes were found in: mean erythropoietin (EPO) doses, blood pressure (BP), phosphorus plasmatic,calcium-phosphorus product, parathormone (PTHi) and vascular access distribution. We explained the absence of any improvement because of adequate start indicators in some areas (BP and vascular access), therapy with limited efficiency (calcitriol, calcium carbonate and others), lack of support resources (dietetic unit) or inadequate design/implementation of improving plans.In conclusion, our intervention illustrates that combined clinical management strategies(feedback, benchmarking and improving plans) are efficiency in improving some areas of haemodialysis treatment (anaemia, dialysis dose, nutrition and inflammation), although it does not improve calcium phosphate metabolism related indicators.

Abstract
Meningiomas are infrequent tumours in infancy but when they appear in this age group, the intraventricular location is more frequent than in adults. We report the case of a 5-year-old girl with intracranial hypertension and a VI nerve palsy. Computed tomography and magnetic resonance imaging of the brain revealed a tumoral lesion involving the right lateral ventricle with intense enhancement after contrast administration. It was completely resected through a mean temporal circunvolution route. Histological diagnosis was of atypical meningioma.

Abstract
OBJECTIVE To determine the location of hyperhidrosis, the accompanying signs and symptoms, and patient anxiety assessed on 2 scales and standardized psychometric instruments. PATIENTS AND METHODS A prospective study of patients with hyperhidrosis was carried out between September 1, 2001 and June 30, 2003 with a self-administered preoperative questionnaire. The variables studied included the location of hyperhidrosis, the accompanying signs and symptoms, and the self-reported degree of anxiety and perception of its effect on daily life assessed by the State-Trait Anxiety Inventory (STAI) and a questionnaire designed in our department. RESULTS Palmar hyperhidrosis was reported by 93.6% of patients, plantar by 70.2%, axillary by 66.4%, facial by 12.1%, groin by 8.2%, chest by 5%, and abdominal by 2%. While more than 50% of the patients reported facial blushing and palpitations as accompanying signs and symptoms, approximately 30% experienced epigastric pain, trembling, and headaches. Over half of the patients reported that their anxiety was incapacitating, and a mere 1.2% experienced none at all. STAI scores were similar to those of the general population whereas scores on our department's questionnaire reflected those of the self-reported anxiety ratings. CONCLUSIONS Primary hyperhidrosis is a disorder in which excessive sweating occurs mainly, but not exclusively, on the palms. The condition is accompanied by signs and symptoms typical of autonomic nervous system hyperactivity and by a degree of anxiety that has an incapacitating effect on normal life, although that anxiety is not detected by the STAI questionnaire alone.
