Abstract
The introduction of the 7-valent pneumococcal conjugate vaccine in children has led to a change in the pattern of pneumococcal serotypes causing pneumococcal disease. The aim of this study was to compare the clinical presentation and outcome of invasive pneumococcal pneumonia (IPP) in adults between the pre and post-vaccine era. We have conducted an observational study of all adults hospitalized with IPP, from 1996 to 2001 (pre-vaccine period), and from 2005 to 2009 (post-vaccine period). Incidence, serotype distribution and clinical data were compared between both periods. A total of 653 episodes of IPP were diagnosed. The overall incidence of IPP increased from 14.2 to 17.9 cases per 100 000 population-year (p 0.003). In the post-vaccine period IPP caused by vaccine serotypes decreased (-36%; 95% CI, -52 to -15) while IPP caused by non-vaccine serotypes increased (71%; 95% CI, 41-106). IPP in the post-vaccine period was associated with higher rates of septic shock (19.1% vs. 31.1%, p <0.001). Among patients aged 50-65 years there was a trend towards a greater proportion of case-fatalities (11.6-23.5%, p 0.087). Independent risk factors for septic shock were IPP caused by serotype 3 (OR 2.38; 95% CI, 1.16-4.87) and serotype 19A (OR 6.47, 95% CI, 1.55-27). Serotype 1 was associated with a lower risk of death (OR 0.1; 95% CI, 0.01-0.78). In conclusion, the incidence of IPP in the post-vaccine period has increased in our setting, it is caused mainly by non-vaccine serotypes and it is associated with higher rates of septic shock.

Abstract
OBJECTIVE to evaluate the effect of LH surge and progesterone rise in IUI cycles under gonadotropin stimulation with GnRH antagonist coadministration on pregnancy rates (PR). STUDY DESIGN The population under study consisted of 152 women prospectively studied and subjected to IUI. RESULTS The higher the progesterone cutoff value, the lower the PR were 26.5% and 10.9% when the cutoff was 1 ng/mL, 26.0% and 8.6% when the cutoff was 1.2 ng/mL, 25.6% and 7.1% when the cutoff was 1.4 ng/mL and 25.3% and 0% when the cutoff was 1.6 ng/mL. CONCLUSION In IUI cycles under GnRH antagonist coadministration, serum progesterone levels over 1.0 ng/mL are associated with lower PR, the higher the progesterone levels, the lower the PR.

Abstract
BACKGROUND CONTEXT Present studies concerning the safety and reliability of neurophysiological monitoring during thoracic pedicle screw placement remain inconclusive, and therefore, universally validated threshold levels that confirm osseous breakage of the instrumented pedicles have not been properly established. PURPOSE The objective of this work was to analyze whether electromyographic (EMG) thresholds, after stimulation of the thoracic pedicle screw, depend on the distance between the neural structures and the screws. The modifier effect of different interposed tissues between a breached pedicle and neural structures was also investigated. STUDY DESIGN This experimental study uses a domestic pig model. METHODS Electromyographic thresholds were recorded after the stimulation of 18 thoracic pedicle screws that had been inserted into five experimental animals using varying distances between each screw and the spinal cord (8 and 2 mm). Electromyographic thresholds were also registered after the medial pedicle cortex was broken and after different biological tissues were interposed (blood, muscle, fat, and bone) between the screw and the spinal cord. RESULTS Mean EMG thresholds increased to 14.1±5.5 mA for screws with pedicle cortex integrity that were placed 8 mm away from the dural sac. After the medial pedicle cortex was broken and without varying the distance of the screw to the dural sac, the mean EMG thresholds were not appreciably changed (13.6±6.3 mA). After repositioning the screw at a distance of 2 mm from the spinal cord and after medial cortical breach of the pedicle, the mean threshold significantly slowed to 7.4±3.4 mA (p<.001). When the screw was placed in contact with the spinal dural sac, even lower EMG thresholds were registered (4.9±1.9, p<.001). Medial pedicle cortex rupture and the interposition of different biological tissues in experimental animals did not alter the stimulation thresholds of the thoracic pedicle screws. CONCLUSIONS In the experimental animals, the observed electrical impedance depended on the distance of screws from the neural structures and not on the integrity of the pedicle cortex. The screw-triggered EMG technique did not reliably discriminate the presence or absence of bone integrity after pedicle screw placement. The response intensity was not related to the type of interposed tissue.

Abstract
OBJECTIVE: Obesity adversely affects frontal lobe brain structure and function. Here we sought to show that people who are obese versus those who are of normal weight over a 5-year period have differential global and regional brain volumes. DESIGN: Using voxel-based morphometry, contrasts were done between those who were recorded as being either obese or of normal weight over two time points in the 5 years prior to the brain scan. In a post-hoc preliminary analysis, we compared scores for obese and normal weight people who completed the trail-making task. SUBJECTS: A total of 292 subjects were examined following exclusions (for example, owing to dementia, stroke and cortical infarcts) from the Prospective Investigation of the Vasculature in Uppsala Seniors cohort with a body mass index of normal weight (<25 kg m−2) or obese (⩾30 kg m−2). RESULTS: People who were obese had significantly smaller total brain volumes and specifically, significantly reduced total gray matter (GM) volume (GMV) (with no difference in white matter or cerebrospinal fluid). Initial exploratory whole brain uncorrected analysis revealed that people who were obese had significantly smaller GMV in the bilateral supplementary motor area, bilateral dorsolateral prefrontal cortex (DLPFC), left inferior frontal gyrus and left postcentral gyrus. Secondary more stringent corrected analyses revealed a surviving cluster of GMV difference in the left DLPFC. Finally, post-hoc contrasts of scores on the trail-making task, which is linked to DLPFC function, revealed that obese people were significantly slower than those of normal weight. CONCLUSION: These findings suggest that in comparison with normal weight, people who are obese have smaller GMV, particularly in the left DLPFC. Our results may provide evidence for a potential working memory mechanism for the cognitive suppression of appetite that may lower the risk of developing obesity in later life.

Recording triggered EMG thresholds from axillary chest wall electrodes: a new refined technique for accurate upper thoracic (T2-T6) pedicle screw placement. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2011; 20:1620-5.

Abstract
This study was aimed at evaluating the sensitivity and safety of a new technique to record triggered EMG thresholds from axillary chest wall electrodes when inserting pedicle screws in the upper thoracic spine (T2-T6). A total of 248 (36.6%) of a total of 677 thoracic screws were placed at the T2-T6 levels in 92 patients with adolescent idiopathic scoliosis. A single electrode placed at the axillary midline was able to record potentials during surgery from all T2-T6 myotomes at each side. Eleven screws were removed during surgery because of malposition according to intraoperative fluoroscopic views. Screw position was evaluated after surgery in the remaining 237 screws using a CT scan. Malposition was detected in 35 pedicle screws (14.7%). Pedicle medial cortex was breached in 24 (10.1%). Six screws (2.5%) were located inside the spinal canal. Mean EMG threshold was 24.44 ± 11.30 mA in well-positioned screws, 17.98 ± 8.24 mA (p < 0.01) in screws violating the pedicle medial cortex, and 10.38 ± 3.33 mA (p < 0.005) in screws located inside the spinal canal. Below a threshold of 12 mA, 33.4% of the screws (10/30) were malpositioned. Furthermore, 36% of the pedicle screws with t-EMG stimulation thresholds within the range 6-12 mA were malpositioned. In conclusion, assessment of upper thoracic pedicle screw placement by recording tEMG at a single axillary electrode was highly reliable. Thresholds below 12 mA should alert surgeons to suspect screw malposition. This technique simplifies tEMG potential recording to facilitate safe placement of pedicle screws at upper thoracic levels.

Abstract
INTRODUCTION The use of M-tor inhibitors plus withdrawal of anticalcineurins after 3 months of posttransplantation is usually linked to improvements in renal function. The long-term effects of substitution of anticalcineurinis by everolimus remain unknown. The aim in this study was to evaluate the evolution of renal function and the proteinuria after a complete switch of long-term functioning allograft patients to everolimus. We treated 30 renal transplanted patients with everolimus, at a mean time posttransplantation of 123.8 +/- 74.2 months. The 27 patients, including 17 treated with tacrolimus and 10 with cyclosporine, who were controlled for at least 6 months were included in this study. Seventeen of them were diagnosed to display chronic allograft nephropathy (CAN). RESULTS The patients with CAN showed a basal creatinine of 1.81 +/- 0.4; with after a year, 1.61 +/- 0.38; and after 2 years, 1.56 +/- 0.49 mg/dL (P < .05). No significant changes were observed among patients without CAN: 1.1 +/- 0.32, 0.97 +/- 0.15, and 0.97 +/- 0.15 mg/dL, respectively. In CAN patients, the protein/creatinine quotient was: basal = 0.30 +/- 0.13, one year = 0.63 +/- 0.68, and 2 years = 0.48 +/- 0.34. In the other patients the values were 0.2 +/- 0.07, 0.73 +/- 0.7, and 0.32 +/- 0.17, respectively, after a late switch to everolimus. CONCLUSION The improved renal function occurred mainly in patients with CAN. Patients who did not suffer from it showed a greater rise in proteinuria. Nevertheless, both groups experienced decreased proteinuria after 2 years.

Abstract
The usefulness of mycophenolate mofetil (MMF) levels in stable kidney transplant patients is not well known. We measured MMF trough levels in 137 adult kidney recipients with more than 1 year of stable graft function. The MMF dose was adjusted according to hematological or gastrointestinal toxicity, it was 500 mg in 22 (16%) patients; 750 mg in 22 (16%); 1000 mg in 69 (50.5%); 1500 mg in 15 (11%); and 2000 mg in 9 (6.5%). We analyzed the total dose, virgule dose/kg, and MMF levels in relation to efficacy parameters (creatinine, proteinuria) and hematological toxicity (erythrocytes, leukocytes, and platelets) at the time of MMF level determinations and 3 months thereafter. Statistical analyses were performed with SSPS 12.0, including sensitivity and specificity analyses by ROC. Mean MMF levels were 3.68 mg/L (Pc25, 1.6-Pc75, 4.4 mg/L) with significant differences according to dose (P < .001). Trough MMF levels did not have discriminatory capacity in the area under the ROC for anemia, renal failure, or proteinuria at the time of determination or 3 months later. The percentage of patients without proteinuria was high among patients with MMF levels between 1.6 and 4.4 mg/L. The MMF levels were low in patients who had a major increase in creatinine (1.6 vs 3.8 mg/L, P < .05). In stable renal transplant patients the levels of MMF were related to the administered dose, and they are higher than those previously described in patients with less than a year follow-up with a functioning kidney. They did not have discriminatory value at the time of determination or 3 months later. Nevertheless, low MMF levels could help recognize patients at risk of developing chronic nephropathy.

Abstract
OBJECTIVE The objective was to define the toxicity and activity of weekly docetaxel administered with a short course of estramustine and enoxaparine in patients with hormone-resistant prostate cancer (HRPC). PATIENTS AND METHODS Twenty-four patients were treated with the next regimen: weekly docetaxel 36 mg/m(2) iv for three consecutive weeks every 28 days, and estramustine 280 mg three times a day for three consecutive days beginning the day before docetaxel (days 1-3, 8-10 and 15-17). In order to prevent thromboembolic events, 40 mg of subcutaneous enoxaparine was administered daily sc on the same days as estramustine. Primary endpoints were: toxicity, especially the presence of thromboembolic events, PSA response rate and response in measurable disease. Secondary endpoints were: time to PSA progression and overall survival. RESULTS Nineteen of 24 patients (79.1%, 95% CI 71-87%) had a PSA response = or >50%. Four of the eleven patients with measurable disease had a partial response. The median time to PSA progression was 7 months (CI 95%: 6.5-9) and the median survival was 19 months (IC 95%: 11-24). Toxicity was manageable with no treatment- related mortality. Only two patients had grade 4 neutropenia. Two patients had thrombotic events, one deep venous thrombosis and one stroke. The main grade 3 non-haematologic toxicity was diarrhoea and asthenia, both in 25% of patients. CONCLUSIONS Weekly docetaxel with a short course of estramustine and enoxaparine is active and tolerable in HRPC patients. The observed incidence of thrombosis was lower than previously reported but the association of enoxaparine was not enough to completely prevent the thromboembolic events.

Abstract
INTRODUCTION Neurophysiological monitoring in spine surgery can be performed by a number of methods, although there is no general agreement about which is the best. AIM The aim of this study was to evaluate our experiences using the method of spinal cord stimulation with recording carried out on the peripheral nerve. PATIENTS AND METHODS We studied 51 patients with scoliosis who were submitted to surgical correction. Stimuli were administered with the cathode located in the dorsal epidural space, two levels above the curve to be corrected, and recording was performed on the posterior tibial nerve in the popliteal fossa. RESULTS Potential was obtained in 78% of cases, with a very low number of averages and the maximum reduction in the amplitude of the potential was found to be 33%. Spinal cord stimulation evokes muscular responses in several muscles and sensory responses in the sural nerve. None of the patients who were monitored using this method presented postoperative neurological deficits added to their previous pathology. CONCLUSIONS The neurogenic potentials obtained by epidural spinal cord stimulation are very useful for monitoring spine surgery because they are very stable, they can be obtained quickly, they avoid the need to interfere with the anaesthetist's field and because, albeit to a small extent, they may contain information about motor pathways. The main drawback is that it is not always possible to place the electrode and that in 22% of cases we have not managed to obtain the motor component and we have therefore had to be cautious in evaluating it, since its disappearance would only give rise to a partial reduction in the potential.

Abstract
The authors present a retrospective study of 23 patients in their growing period who underwent resection of more than 2 cm of the fibula. Long-term effects in the ankle and tibia were analyzed. The patients were radiologically studied using the contralateral side as control. Representative radiologic findings were distal migration of the fibula head in 75% (but without clinical relevance), thickening of the external tibial cortex in 20%, talar tilt in 45%, proximal migration of the lateral malleolus in 55%, and diaphyseal valgus of the tibia in 20% of the cases. Incomplete regeneration of fibula was observed in 58% of the cases. Two patients suffered a spiral diaphyseal fracture and another a slow physeal fracture of the distal tibia. In this study, many radiologic changes were observed after fibula resection. The authors suggest using reconstruction methods after fibula resection when it is possible.

Abstract
AIMS To analyse the long-term outcome of the largest reported cohort of patients presenting asystole during head-up tilt test. METHODS AND RESULTS Since 1990, 1322 patients with syncope of unknown origin have undergone tilt-table testing. Of those, 330 patients (24 X 9%) presented an abnormal response (syncope or pre-syncope). Furthermore, 58 of those patients (17 X 5%) suffered a period of asystole (> or = 3000 ms) during the test. Asystole (median (interquartile range)) lasted 10 (4, 19 X 2) s (range 3-90). Two different protocols (angles) of tilting (Westminster (60 degrees) n=1124; isoproterenol (80 degrees) n=198)) influenced the time to the syncopal episode (13 (6 X 5, 20 X 5) vs 2 (1, 6 X 5) min, P=0,0005) but not the duration of the asystole. During this period, therapy for asystole featured three different stages: first patients were treated with pacemakers; later drug therapy (metoprolol and/or etilefrine) was recommended; lastly (from 1995), no specific treatment was given. In a cohort age- and gender-matched study, those patients without were compared to those with asystole in a 2:1 basis. During 40 X 7 months of follow-up (17 X 7, 66 X 8), 12 patients (20 X 6%) with asystole had syncopal recurrences. Furthermore, 34 patients (28 X 8%) without asystole presented syncopal episodes during a follow-up of 51 X 6 months (29 X 3, 73 X 1) (P=ns). The Kaplan-Meier analysis in patients with and without asystole showed a mean time free of recurrence of 92 X 6 +/- 6 months vs 82 X 6 +/- 4 X 7 months (P=ns). The previous number of syncopes had a significant relationship with recurrences (P=0 X 002), but not therapy. There were no cardiac related deaths. CONCLUSIONS (1) Asystole during head-up tilt test does not imply a malignant outcome and syncope recurrence is low; (2) pacemaker or drug therapy do not significantly influence outcome which correlates to the previous number of syncopal episodes but not to gender, age, asystole occurrence, asystole duration and timing to asystole during head-up tilt test; (3) tilting protocol (angle) might influence time to and incidence of asystole during head-up tilt test.

Abstract
AIMS Syncope is a common occurrence, the prevalence of which increases with age, and among the multiple causes of syncope, neurally mediated syncope is thought to be a frequent cause in the young and in the elderly. Head-up tilt table testing (HUT) has become the diagnostic test of choice for neurally mediated syncope, the response to which varies clearly with age. The purpose of this study is to report the differences among patients suffering syncope referred for HUT, and the influence of age and gender on HUT results (percentage of positive responses and response patterns) in two study protocols (basal and isoprenaline). METHODS AND RESULTS One thousand, two hundred and nineteen patients with syncope were referred to the authors' Cardiology Department for HUT from September 1990 to April 2000; 1061 undergoing basal HUT (Group A) and 158 undergoing isoprenaline tilt table testing (Group B). Complications were noted in neither protocol. Females were more frequent among young people, and males in the elderly (P<0.05). Head-up tilt table testing was abnormal in 259 (24.4%) patients in Group A and in 85 (53.7%) patients in Group B (P<0.05), and no gender differences were observed. The positive rate of tests in men and women significantly declined with age in Group A (P<0.05), but not in Group B (P=ns). There were no differences in the patterns of haemodynamic collapse in both groups. CONCLUSIONS In the study of syncope, basal HUT has a high positive rate in young people; a decrease in positive rate with age suggests, however, the need for using another protocol with a similar diagnostic accuracy in the elderly.

Abstract
The effect of manothermosonication (MTS), an emergent technology for food preservation, on thiamin, riboflavin, carotenoids, and ascorbic acid was evaluated in milk and orange juice. The effect of both heat treatment and MTS on several compounds produced in nonenzymatic browning in model systems was also studied. MTS does not affect significantly the nutrient content studied. However, it changes the behavior of nonenzymatic browning. No formation of 5-(hydroxymethyl)-2-furfuraldehyde (HMF) was detected in fruit juice model systems after heat and MTS treatments at the experimental conditions used. In a milk-resembling system, free HMF formation by MTS is higher compared to that by heat treatment. As the MTS temperature increases, free HMF production by both treatments equaled on another. For bound HMF the production rate is lower by MTS than by heat treatment under the experimental conditions used. Formation kinetics of brown pigments and that of fluorescent compounds are different for both treatments. Fluorescence and brown pigment production are faster in MTS.

Abstract
Heart transplantation is contraindicated as an effective treatment for end-stage Chagas' heart disease because of post-operative recurrence of Trypanosoma cruzi infection and reactivation of disease after immunosupression. In a follow-up study of a heart transplanted patient with Chagas' disease, we prospectively evaluated the usefulness of the polymerase chain reaction (PCR) for early diagnosis of reactivation. We monitored post-operative recurrence of Trypanosoma cruzi infection with microscopic observation of the parasite in peripheral blood (Strout's method), endomyocardial biopsies (EMBs), skin lesions, and 2 PCR assays, based on the amplification of specific T cruzi kinetoplastid and nuclear DNA sequences. During follow-up, parasite DNA was amplified in blood samples and EMB sections 41 days before we observed patent parasitemia and cutaneous manifestations of reactivation, proving that PCR is much more sensitive than direct microscopic observation for early diagnosis of disease reactivation in heart-transplanted Chagas' disease patients.

Abstract
BACKGROUND Peak oxygen uptake (peak VO(2)) is a reference parameter in the assessment of functional capacity of patients with chronic heart failure, but the procedure for cardiopulmonary exercise testing with expired gas analysis is complex and expensive, so more simple and available methods are desirable. METHODS We compared the usefulness of a time-limited walk test, the 6-minute walk test (6-MT), with that of a symptom-limited walk test, the shuttle walk test (SWT), in the evaluation of patients with moderate to severe chronic heart failure. We prospectively studied 46 clinically stable patients in New York Heart Association class II to IV heart failure with left ventricular ejection fraction <40% (aged 53 +/- 10 years, ejection fraction 23% +/- 8%, New York Heart Association functional class 2.8 +/- 0.7). Each patient performed two 6-MT, two SWT and a cardiopulmonary exercise testing within 2 weeks. RESULTS We found a close correlation between distance walked in SWT and peak VO(2 ) (r = 0.83, P <.001) and a moderate correlation between distance in 6-MT and peak VO(2) (r = 0.69, P <.001). Both walk tests showed to be reproducible after just one practice walk. All patients who walked > 450 m in SWT had a peak VO(2) >14 mL/kg/min. The overall discriminatory accuracy for SWT distance was greater than that for 6-MT distance for predicting a peak VO(2 ) <14 mL/kg/min (area under receiver operator characteristic curves 0.97 and 0.83 respectively, P =.02). Stepwise multivariate regression analysis, including clinical, exercise testing, echocardiographic, radionuclide-angiographic, and rest hemodynamic data, showed that distance walked in SWT was the only independent predictor of peak VO(2) (P <.001) and the strongest predictor of percent achieved of age- and sex-predicted peak VO(2) (%PVO(2)) (P <.001), with only age offering additional information (P =.02). CONCLUSIONS The SWT shows to be a feasible and safe method to evaluate patients with chronic heart failure that strongly and independently predicts peak VO(2) and %PVO(2.) This symptom-limited walk test seems to be more useful than 6-MT in the assessment of functional capacity in these patients.

Abstract
Pectinmethylesterase of navel oranges shows two fractions greatly differing in thermostability. The most thermostable fraction accounts for approximately 10% of total activity. The thermal inactivation of this fraction follows first-order kinetics both in 5 mM, pH 3.5, citrate buffer and in orange juice at the same pH, showing a z value of 5.1 degrees C and an activation energy (E(a)) of 435 kJ mol(-)(1) K(-)(1). The heat resistance of the enzyme is approximately 25-fold higher in the juice than in citrate buffer. When ascorbic acid, sucrose, glucose, and fructose are added to the citrate buffer at the concentrations found in orange juice, the heat resistance of the enzyme increases 3-fold. The addition of pectin at 0.01% concentration multiplies it by a factor of 50. Manothermosonication (MTS), the simultaneous application of heat and ultrasound under moderate pressure (200 kPa), at 72 degrees C, increases the inactivation rate 25 times in buffer and >400 times in orange juice. MTS inactivation shows a higher z value (35.7 degrees C) and lower E(a) (56.9 kJ mol(-)(1) K(-)(1)) than simple heating.

Abstract
STUDY DESIGN A technique for anterior endoscopic exposure of the thoracolumbar spine is described. OBJECTIVE To develop an endoscopic approach to the thoracolumbar spine with fewer complications than are encountered in the conventional approach. SUMMARY OF BACKGROUND DATA The efficacy of the anterior endoscopic approach to the thoracic spine has been shown. The thoracolumbar hinge is usually approached by open surgery. METHODS The study was performed in three stages. The first phase was carried out on experimental animals (pigs). Once the bases were established, the approach was studied in fresh cadavers. Finally, it was performed on three patients with thoracolumbar scoliosis who required discectomy and anterior release. RESULTS After a series of attempts on the animals, it was found that the most effective method for exposure of the thoracolumbar spine was the initial thoracoscopic approach followed by the retroperitoneal endoscopic approach. This was confirmed in cadavers. When applied to the clinical situation, there were no significant complications in any of the patients treated with this method, and postoperative pain and discomfort were minimal. CONCLUSIONS The anterior endoscopic approach to the lumbar spine involves minor trauma, results in rapid recovery and less pain, and produces good results aesthetically.

Abstract
A dehumidification system for low gravity plant growth experiments requires the generation of no free-liquid condensate and the recovery of water for reuse. In the systems discussed in this paper, the membrane is a barrier between the humid air phase and a liquid-coolant water phase. The coolant water temperature combined with a transmembrane pressure differential establishes a water flux from the humid air into the coolant water. Building on the work of others, we directly compared different hydrophilic membranes for humidity control. In a direct comparison of the hydrophilic membranes, hollow fiber cellulose ester membranes were superior to metal and ceramic membranes in the categories of condensation flux per surface area, ease of start-up, and stability. However, cellulose ester membranes were inferior to metal membranes in one significant category, durability. Dehumidification systems using mixed cellulose ester membranes failed after operational times of only hours to days. We propose that the ratio of fluid surface area to membrane material area (approximately = membrane porosity) controls the relative performances among membranes. In addition, we clarified design equations for operational parameters such as the transmembrane pressure differential. This technology has several potential benefits related to earth environmental issues including the minimization of airborne pathogen release and higher energy efficiency in air conditioning equipment. Utilizing these study results, we designed, constructed, and flew on the space shuttle missions a membrane-based dehumidification system for a plant growth chamber.

Abstract
The aims of this study were two-fold: first, to assess the relative diagnostic performance of non-isotopic in situ hybridization (ISH) and the nested polymerase chain reaction (nested-PCR) applied to Epstein-Barr virus (EBV) detection in a series of 55 unselected nasopharyngeal carcinoma (NPC) cases and, secondly, to correlate these data with histopathological classification. Our study shows that in 76.36% of NPC cases positive nuclear signals were observed using EBV-ISH. Overall, EBV-ISH positivity varied according to histological type, in that undifferentiated carcinomas showed a higher proportion of positive cases than differentiated cell carcinomas, although ISH results do not show significant differences in relation to histological types when employing two different schemes (WHO and Micheau). However, in adequate quality DNA samples (54 NPC cases), EBV-DNA was detected in 100% of cases using a nested-PCR, supporting the previous view that all histological types of NPC are in reality variants of EBV-infected neoplasia. ISH-negative cases probably reflect a lower sensitivity than PCR, particularly when a small number of viral copies are present, as well as a variable technical effectiveness for detected EBV, independent of the NPC histological type.

Abstract
We report the retrospective results of 17 displaced radial neck fractures (O'Brien type II-III) in children aged between 6 and 16 years treated with closed intramedullary pinning according to the Metaizeau technique, from 1988 to 1992 in our Pediatric Orthopaedic Service at the Ramón y Cajal Hospital. The average follow-up was 4.1 years. Excellent results were observed in all cases except one (94%). Overgrowth of the radial head was present in three cases without functional impairment. We recommend this closed method of treatment because it is simple, easy to perform, and obtains exciting results with few complications.

Abstract
Proximal tibiofibular dislocation is an exceptional lesion. Rarer still is its presentation in childhood. We describe the clinical case of a 6-year-old boy, the victim of a road accident. He had a tibiofibular dislocation associated with a metaphyseal fracture of the tibia.

Abstract
The prognostic value of DNA content measured by means of flow cytometry was analyzed in formalin-fixed, paraffin-embedded samples from 231 breast cancer patients treated between 1984 and 1988, with a mean follow-up period of 55 months. We followed the guidelines of a Consensus Meeting held on this issue in Maine, USA, in 1992. DNA-diploid and -aneuploid tumors were evaluated separately for the fraction of cells in S-phase (SPF) contained in them, this being divided into three groups ('high', 'intermediate', and 'low'), defined by the 25th and 75th centile of the SPF-distribution corresponding to either DNA-diploid or DNA-aneuploid tumors. Unequivocally readable histograms were obtained from 174 samples (75.3%). A high SPF in diploid tumors was significantly associated with a higher recurrence rate (p = 0.015), a shorter disease-free survival (p = 0.014), advanced (IIIB) clinical stage (p = 0.034), and almost significantly with total survival (p = 0.055). In a multivariate Cox regression analysis, a high SPF in diploid tumors retained its independent prognostic power, being significantly associated with a shorter disease-free survival (p = 0.00049) and total survival (p = 0.0077). It also allowed to identify a subgroup with an ominous prognosis among patients < or = 50 years of age with early stage tumors. Our results fully validate the recommendations of the 1992 Maine Consensus Meeting.

Abstract
Serum levels of sICAM-1 and sVCAM-1 adhesion molecules as well as TNF cytokine were measured in 50 kidney transplant recipients [14 patients with stable graft function, 18 patients with acute rejection, 10 patients with CsA toxicity, 6 patients with ATN, and 2 patients with cytomegalovirus (CMV) disease] during the first 3 postoperative weeks. All the patients studied showed, on the first posttransplant day, elevated serum levels of sICAM-1 (260 +/- 53 ng/mL). Interestingly, all the patients with good graft function presented thereafter a reduction of sICAM-1 serum levels close to the normal values (185.2 +/- 40 ng/mL). In contrast, the group of patients with acute allograft rejection showed significantly increased serum levels of sICAM-1 (371.5 +/- 86 ng/mL; p < 0.001), 3-4 days before diagnosis of acute rejection. Although sVCAM-1 levels were increased in both acute graft rejection (2263 +/- 106) and CsA toxicity (1650 +/- 315) patients, such increase was not significant among either group of patients when the group with CsA toxicity was compared with either ATN (1320 +/- 204) or stable renal function (1089 +/- 167). No statistical differences in the levels of TNF were demonstrated between the different groups of patients studied. Our findings demonstrate that quantitative determination of serum sICAM-1 may be of predictive clinical value in transplanted patients with acute renal allograft rejection.

Abstract
Percutaneous transcatheter sclerosis with iodate-povidone has been proposed as a treatment of posttransplant lymphocele. We treated 19 lymphoceles with iodate-povidone, 10 of them totally resolved and 6 promptly recurred. Three recurrences were treated conservatively and in 3 the treatment was repeated with success. Therefore, we have a low recurrence and retreatment rate. Our total resolution rate was 100%. Complications due to the treatment were rare. In the long term no patient has developed any renal or perirenal complication related to iodine sclerosis. We conclude that iodine sclerosis is a safe and effective treatment of posttransplant lymphocele. We think that surgical procedures must be reserved to collections adjacent to renal hilum or inaccessible for safe puncturing.

Abstract
The cases of 35 patients in whom a triplane fracture had been treated at the Ramón y Cajal Hospital were reviewed. The diagnosis of biplane and triplane fracture can now be made by standard radiograph. However, plain radiographs alone did not accurately demonstrate the configuration of the fracture, and computed tomography must be performed. Closed reduction should be attempted first. Failure to obtain or maintain (or both) an adequate closed reduction is an indication for operative treatment. Prognosis is surprisingly good. Only when adequate reduction (< 2 mm displacement) has not been achieved can degenerative changes be seen at long-term follow-up (> 5 years).
