Abstract
BACKGROUND Isolated gastrocnemius contracture has been associated with more than 30 lower limb disorders, including plantar heel pain/plantar fasciitis, Achilles tendinosis, equinus foot, adult flatfoot, and metatarsalgia. Although many techniques are available for gastrocnemius recession, potential anesthetic, cosmetic, and wound-related complications can lead to patient dissatisfaction. Open and endoscopic recession techniques usually require epidural or general anesthesia, exsanguination of the lower extremities and stitches and can damage the sural nerve, which is not under the complete control of the surgeon at all stages of the procedure. The purpose of this study is to evaluate the clinical results of a surgical technique for gastrocnemius lengthening with a needle, as previously described in cadaver specimens. METHODS AND RESULTS We performed a prospective study of ultrasound-guided gastrocnemius tendon lengthening in level II using a needle in 24 cases (19 patients) of gastrocnemius contracture. The study population comprised 12 males and 7 females. Mean age was 41 years (18-64). All but 5 recessions were bilateral and occurred simultaneously. The indication for the procedure was gastrocnemius contracture; although the patients also presented other conditions such as non-insertional Achilles tendinopathy in 6 patients (2 were bilateral), insertional Achilles calcifying enthesitis in 4 (1 was bilateral), metatarsalgia in 4, flexible flat foot in 1 and plantar fasciitis in 5 (2 were bilateral). The inclusion criteria were the failure of a previous conservative protocol, that the Silfverskiöld test was positive, and that the pathology suffered by the patient was within the indications for surgical lengthening of the patients and were described in the scientific literature. The exclusion criteria were that the inclusion criteria were not met, and patients with surgical risk ASA 3 or more and children. In these patients, although possible, it is preferable to perform the procedure in the operating room with monitoring, as well as in children since they could be agitated during the procedure at the office. We used the beveled tip of an Abbocath needle as a surgical scalpel. All patients underwent recession of the gastrocnemius tendon, as in an incomplete Strayer release. We evaluated pre- and postoperative dorsiflexion, outcomes, and procedural pain (based on a visual analog scale and the American Orthopedic Foot and Ankle Society scores), as well as potential complications. No damage was done to the sural bundle. RESULTS Ankle dorsiflexion increased on average by 17.89°. The average postoperative visual analog score for pain before surgery was 5.78, 5.53 in the first week, 1.89 at 1 month, and 0.26 at 3 months, decreasing to 0.11 at 9 months. The mean postoperative American Orthopedic Foot and Ankle Society Ankle-Hindfoot score the average was 50.52 before surgery, 43.42 at 1 week, 72.37 at 1 month, 87.37 at 3 months, and 90.79 at 9 months. CONCLUSION Ultrasound-guided needle lengthening of the gastrocnemius tendon is a novel, safe, and effective technique that enables the surgeon to check all the structures clearly, thus minimizing the risk of neurovascular damage. The results are encouraging, and the advantages of this approach include absence of a wound and no need for stitches. Recovery is fast and relatively painless. A specific advantage of ultrasound-guided needle lengthening of the gastrocnemius tendon is the fact that it can be performed in a specialist's office, with a very basic instrument set and local anesthesia, thus reducing expenses.

Abstract
BACKGROUND The cryptic Aspegillus species are rare, these microorganisms are usually more resistant to common antifungal therapies. Therefore, a correct identification is important when evaluating the impact of such species in aspergillosis. AIMS We aimed to describe the frequency, clinical and microbiological characteristics, and the outcomes of those cases of aspergillosis caused by cryptic species in a tertiary hospital. METHODS We retrospectively identified all microbiologically documented cases of aspergillosis between January 2013 and December 2018. Definitive species identification of clinically significant isolates was achieved via sequencing methods. The polymerase chain reaction (PCR) products were sequenced, and the results obtained were compared to sequences deposited in GenBank. Antifungal susceptibility testing was performed using the Sensititre® YeastOne® panel. RESULTS A total of 679 Aspergillus isolates were recovered from 489 patients, of which 109 were clinically relevant. Ten (9.2%) isolates were identified as cryptic species: Aspergillus arcoverdensis (2), Aspergillus lentulus (2), Aspergillus ellipticus (2), Aspergillus alliaceus (1), Aspergillus nomius (1), Aspergillus tubingensis (1) and Aspergillus montevidensis (1). Most patients already suffered some type of immunosuppression. Half of these patients had required intensive care before the infection showed up, and most of them had a pulmonary infection. Mortality at the 100-day follow-up was 40%. Antifungal susceptibility testing was performed on three of the isolates (A. arcoverdensis, A. tubingensis and A. nomius), which showed high minimum inhibitory concentrations (MIC) for azoles and amphotericin B. CONCLUSIONS The frequency of cryptic species in our centre was 9.2%. Most patients had some degree of immunosuppression, and the mortality rate was 40%.

Abstract
BACKGROUND This study aims to analyze the clinical outcome of a new ultrasound-guided surgery for partial plantar fasciotomy performed with a needle for treatment of plantar fasciitis. METHODS We performed a retrospective review of 107 patients diagnosed with plantar fasciitis who underwent ultrasound-guided release of the plantar fascia. The series included 62 males (57.9%) and 45 females (42.1%) treated between April 2014 and February 2018, with a mean follow-up of 21.05 ± 10.96 months (7-66) and a minimum follow-up of 24 months. The mean age was 48.10 ± 10.27 years (27-72). Clinical assessments and ultrasound examination were carried out before treatment, after 1 week, and then after 1, 3, 12, and 24 months. The clinical assessment was based on a visual analog scale and the Foot and Ankle Disability Index. RESULTS Heel pain improved in 92.5% (99) of patients, but not in 7.4% (8 patients). In the group of patients whose heel pain improved, 9 experienced overload on the lateral column and dorsum of the foot, which improved with the use of plantar orthoses and a rehabilitation program. We recorded no nerve complications (e.g., paresthesia), vascular injuries, or wound-related problems. CONCLUSION Ultrasound-guided partial plantar fasciotomy with a needle is safe, since structures are under direct visualization of the surgeon and the risk of damage is minimal. Stitches are not necessary, and recovery is fast. Consequently, costs are low, and the patient can return to work quickly. This technique may represent a valid option for treatment of plantar fasciitis.

Abstract
Background This study aims to analyse the clinical results of ultrasound-guided surgery for the decompression of the tibial nerve, including its distal medial and lateral branches, to treat tarsal tunnel syndrome. These structures are the complete flexor retinaculum and the deep fascia of the abductor hallucis muscle, including individualised release of the medial and lateral plantar nerve tunnels. Method This is a retrospective review of 81 patients (36 men and 45 women) with an average age of 41 years old (32–62) and an average clinical course of 31 months (8–96) compatible with idiopathic tarsal tunnel syndrome, who underwent ultrasound-guided decompression of the proximal and distal tarsal tunnel between February 2015 and November 2017 (both months included), with a minimum follow-up of 18 months. Results Based on the Takakura et al. scale for the 81 patients, 76.54% obtained excellent results, 13.58% good results, and 9.87% poor results. The patients with the longest course of symptoms displayed the worst results. Conclusion Although 9% of patients did not improve, ultrasound-guided tarsal tunnel release might be a viable alternative to conventional open approaches.

Abstract
Background Treatments for Hepatitis C virus (HCV) infection have vastly improved over the past few decades with current regimens now offering pangenotypic activity with excellent cure rates reported in clinical trials, including in the HIV-HCV coinfected population. However, there is some concern that stringent inclusion and exclusion criteria in the trials may lead to results that are not achievable in real-world populations. Methods Our study evaluated a real-world HIV-HCV coinfected population and compared them to the eligibility criteria for trials of two of the most recent approved HCV agents; sofosbuvir/velpatasvir and glecaprevir/pibrentasvir. Results Our study included 219 HIV-HCV coinfected patients and found that 89% met exclusion criteria for the sofosbuvir/velpatasvir trial and 90% met exclusion criteria for the glecaprevir/pibrentasvir trial. The majority of patients met more than one exclusion criteria with the most frequent criteria for exclusion being a non-approved ART regimen (58 and 47% respectively), having a psychiatric disorder (52%), active alcohol or injection drug use (27%), having an HIV viral load > 50 copies/ml (15%), a CrCl < 60 ml/min (13%) and a history of decompensated cirrhosis (13%). Conclusion Although the newer Hepatitis C treatments are very effective, the real world HIV-HCV coinfected population often have comorbidities and other characteristics that make them ineligible for clinical trials, such that they are barriers to treatment. These barriers need to be recognized and addressed in order to optimize treatment outcomes in the HIV patient population.

Abstract
OBJECTIVE To determine whether maternal diet supplementation with omega-3 long chain polyunsaturated fatty acids (omega-3 LC-PUFAs) during the last trimester of pregnancy and the breastfeeding period influences the levels of inflammatory cytokines in mother and infants. MATERIAL AND METHOD This registered, double-blind randomized study included 46 pregnant women, who were randomly allocated to either an experimental group receiving 400mL/day of a fish oil-enriched dairy drink [320mg docosahexaenoic acid (DHA) + 72mg eicoapentaenoic acid] (FO group, n = 24) or to a control group receiving 400mL/day of a non-supplemented dairy drink (CT group, n = 22), from week 28 of pregnancy until the fourth month of lactation. During the study, maternal dietary patterns were monitored by a nutritionist, who encouraged compliance with current recommendations of fatty acids intake. DHA concentrations and cytokine levels (GM-CSF, IL-2, IL-4, IL-6, IL-10, INF-γ and TNF-α) were measured in maternal plasma at the moment of recruitment and in maternal (n = 46) and infant (n = 46) plasma at birth and 2.5 months after birth. RESULTS Maternal plasmatic IL-4 levels were higher in FO than in CT subjects (p = 0.009). Additionally, a tendency was observed to higher IL-10 and IL-2 in the FO group. Plasmatic IL-6 however, was higher in CT mothers (p = 0.001). TNF-α was higher in CT infants at birth and 2.5 months after birth (p = 0.005). An analysis of possible relationships between DHA and the concentrations of different cytokines revealed negative correlation between maternal plasmatic IL-6 and DHA (higher plasmatic DHA corresponded to lower IL-6). CONCLUSIONS Maternal dietary omega-3 LC-PUFAs supplementation during critical periods like pregnancy, lactation and early newborn development may influence the levels of certain inflammatory cytokines, reducing pro-inflammatory cytokines and promoting an anti-inflammatory "environment".

Abstract
The next generation of ionic liquids must be synthetized taking into account structures that guarantee the suitable properties for a defined application as well as ecological data. Thus, searching of the right methodologies to know, quickly and efficiently, the ecological effects of these compounds is a preliminary task. The effects of two imidazolium based ionic liquids with different anions, 1-butyl-3-methylimidazolium tetrafluoroborate, [C4C1Im][BF4], and 1-propyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [C3C1Im][NTf2], on seedling emergence of six tree species and on the microbial behaviour of two soils were determined in this work. Results showed that the highest doses of both ionic liquids caused the total inhibition of germination for almost all the species studied and that the seeds are more sensitive to the presence of these compounds than soil microbial activity. Nevertheless, signals of stress and death are observed from the results of heat released by microorganisms after the addition of the highest doses of both ionic liquids. The novelty of this work resides in the enlargement of knowledge of toxicity of ILs on complex organisms such as arboreal species and microbial activity of soils studied for the first time through a microcalorimetric technique.

Abstract
IntroductionWe present the case report of a 21-year-old Chinese female, who was brought to the emergency department. We open the debate between the operative criteria stablished by DSM-5 of the clinical entity dissociative amnesia and Shenjing Shuairuo - the Chinese “culture-bound syndrome”.ObjectivesTo expose the relevance of the cultural formulation in the clinical evaluation of patients with a different non-Western culture in Psychiatry.AimsThe Shenjing Shuairuo syndrome (“nervous system weakness”) was originally descripted in China, it has a gradual onset, usually after a stressful event. It involves a minimum 3 of 5 symptoms group: weakness, emotions, excitement, neurological pain and sleep. This complex group of symptoms overlap with dissociative syndrome such as dissociative amnesia.Methods/resultsThe cultural formulation interview (CFI) was used for the diagnostic and subsequent treatment of dissociative amnesia with fugue in a different culture patient who met the clinical criteria of this two divergent clinic entities.ConclusionsIn our clinical practice, we will deal with different culture patients, who could present common clinical entities or with the so-called “culture-bound syndromes”. The cultural formulation of the clinical cases will help the clinicians to diagnose and have better treatment's options in clinical manifestations do not correspond to the conventional entities included in mostly Western-based nomenclatures.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
UNLABELLED Phototherapy for hyperbilirubinemia has rare complications. We report a case of phototherapy induced eruption in a neonate with transient porphyrinemia. Our patient received phototherapy due to hyperbilirubinemia secondary to erythroblastosis fetalis (hemolytic disease of the newborn). He developed a cutaneous rash in the light-exposed areas of his skin. Erythrocyte and plasma porphyrins were elevated at the time. Phototherapy induced eruption with a transient porphyrinemia is rare. Upon review of the literature, we found only 5 other cases of patients with phototherapy induced rash and elevated porphyrins reported. We compared the five other reported cases to our case, looking at drug exposure, age, and receipt of exchange transfusion. CONCLUSION While this is an uncommon occurrence, transient porphyrinemia should be considered in neonates with phototherapy induced cutaneous eruption and erythroblastosis fetalis.

Abstract
En el presente trabajo se determinó la respuesta inmune posterior a las campañas de vacunación antirrábica masiva realizadas en 19 distritos de la ciudad de Lima. El método utilizado fue la titulación de anticuerpos antirrábicos mediante la prueba de seroneutralización en ratón, técnica que fue aplicado a un muestreo significativo de sueros sanguíneos de la población de canes vacunados. Se tomaron al azar 54 muestras de canes mordedores que ingresaron al Centro Antirrábico de Lima para ser observados clínicamente por un periodo de 10 días. De las 54 muestras de suero que se sometieron a la prueba, 28 (52%) fueron positivos (títulos de 0,5-8,39 UI/ml), mientras que las 26 (48%) muestras restantes dieron títulos inferiores a 0,5 UI/ml y otros fueron negativos a la prueba. El grupo etáreo de mayor muestreo correspondió a la población de canes de más riesgo (1-3 años de edad). En este grupo etáreo, 14 canes (26%) presentaron sueros con títulos de protección, mientras que en 18 canes (33%) la prueba fue negativa. En lo referente al sexo, el grupo de canes machos (considerados de mayor riesgo) presentaron mayor número de individuos (44 canes) respecto al grupo de hembras (10 canes) y solo en 24 canes machos (45%) dieron títulos de protección antirrábica. En conclusión, podemos decir que el 52% de canes vacunados durante las anteriores campañas de vacunación antirrábica masiva en la ciudad de Lima, en 1993, tuvieron títulos de anticuerpos protectores contra el virus de la rabia.

Abstract
La artrosis de la base del pulgar es una de las patologías más frecuentes en la mano. Tras el tratamiento conservador, son muchos los tratamientos descritos para el tratamiento de la misma (artrodesis, artroplastia, artroplastia de interposición…). En el presente trabajo presentamos la técnica de Zancolli modificada para el tratamiento de la rizartrosis, Es una técnica quirúrgica fiable y reproducible para el tratamiento de la rizartrosis en estadio III-IV, con buenos resultados y bajo índice de complicaciones. Hemos desarrollado algún cambio técnico de la técnica original, que permite realizar la cirugía con una menor incisión y obtener tendones abductores accesorios de mayor longitud. Esto permite disminuir la morbilidad quirúrgica y en cierto modo disminuir las complicaciones, aumentando el volumen de suspensión-interposición. Una de las ventajas principales es el corto tiempo de inmovilización y los buenos porcentajes de pacientes libres de dolor (95%) con una pinza estable y fuerte.

Abstract
Distal mouse chromosome 16 (MMU16) shares conserved linkage with human chromosome 21 (HSA21), trisomy for which causes Down syndrome (DS). A 4.5-Mb physical map extending from Cbr1 to Tmprss2 on MMU16 provides a minimal tiling path of P1 artificial chromosomes (PACs) for comparative mapping and genomic sequencing. Thirty-four expressed sequences were positioned on the mouse map, including 19 that were not physically mapped previously. This region of the mouse:human comparative map shows a high degree of evolutionary conservation of gene order and content, which differs only by insertion of one gene (in mouse) and a small inversion involving two adjacent genes. "Low-pass" (2.2x) mouse sequence from a portion of the contig was ordered and oriented along 510 kb of finished HSA21 sequence. In combination with 68 kb of unique PAC end sequence, the comparison provided confirmation of genes predicted by comparative mapping, indicated gene predictions that are likely to be incorrect, and identified three candidate genes in mouse and human that were not observed in the initial HSA21 sequence annotation. This comparative map and sequence derived from it are powerful tools for identifying genes and regulatory regions, information that will in turn provide insights into the genetic mechanisms by which trisomy 21 results in DS.

Abstract
The distal end of human Chromosome (HSA) 21 from PDXK to the telomere shows perfect conserved linkage with mouse Chromosome (MMU) 10. This region is bounded on the proximal side by a segment of homology to HSA22q11.2, and on the distal side by a region of homology with HSA19p13.1. A high-resolution PAC-based physical map is described that spans 2.8 Mb, including the entire 2.1 Mb from Pdxk to Prmt2 corresponding to HSA21. Thirty-four expressed sequences are mapped, three of which were not mapped previously in any species and nine more that are mapped in mouse for the first time. These genes confirm and extend the conserved linkage between MMU10 and HSA21. The ordered PACs and dense STS map provide a clone resource for biological experiments, for rapid and accurate mapping, and for genomic sequencing. The new genes identified here may be involved in Down syndrome (DS) or in several genetic diseases that map to this conserved region of HSA21.

Abstract
OBJECTIVE To find the sort of information given to cancer patients in PC and the factors which affect the disclosure of the diagnosis. DESIGN A descriptive crossover study, carried out through a personal interview. SETTING A county hospital with no oncology service. PATIENTS All those patients with cancer (histologically confirmed) admitted to the hospital during April and May 1993. MEASUREMENTS AND MAIN RESULTS Each patient was asked what illness he/she had, who told him/her and where, along with his/her sociodemographic details. Later the date of diagnosis and the site and spread of the tumour were taken from the medical records. Out of 108 patients under study, 8 knew they had cancer, 1 said he/she had a tumour and 11 believed they had "something bad". 7 patients had no information about their illness and 81 gave alternative diagnoses (inflammation, cyst...). Disclosure was more common in the cases of breast cancer, haematological cancer and those diagnosed over 6 months previously. No significant differences regarding the spread of the tumour or the sociodemographic variables were found. CONCLUSIONS The disclosure of a diagnosis of cancer is the exception, not the rule. Concealment is only abandoned in the case of potentially curable tumours and those which offer a longer life expectancy.

Abstract
We investigated the shelf life of fresh Tilapia spp. fillets packaged in high-barrier film under both 100% air and a modified atmosphere (MA) of 75% CO2:25% N2, and stored under refrigeration (4°C) and abuse temperatures (8 and 16°C). The chemical spoilage indicators trimethylamine, K-value, and surface pH, as well as microbial counts, were compared with the sensory characteristics of spoilage. For fillets packaged under 100% air, the shelf life was 9 to 13 days at a storage temperature of 4°C, but decreased to 3 to 6 days at 16°C. However, the shelf life of MA-packaged fillets stored at 4°C increased to >25 days when the lag phase and generation time of the bacteria were extended. MA packaged fillets stored under temperature-abuse conditions (8 and 16°C) had a shorter shelf life. The trimethylamine content associated with onset of sensory spoilage for MA packaged fillets increased as storage temperature increased and differed for each temperature. The surface pH and K-values of MA-packaged fillets were not good indicators of spoilage onset.

Environmental air samples were collected with personal diffusive samplers by adsorption on activated charcoal during exposure and from end-expired air (alveolar air) on cartridges of activated charcoal after exposure. Both compounds were desorbed with carbon disulphide and analysed by gas chromatography. Linear regression analyses showed a good correlation between environmental and end-expired air concentrations (r = 0.82 for n-hexane and r = 0.81 for toluene). These correlations allowed us to calculate the concentrations in expired air corresponding to current environmental limit values. The calculated concentrations in end-expired air that correspond to current environmental threshold limit values of 176 mg m-3 for n-hexane and 377 mg m-3 for toluene are 28 mg m-3 (95% confidence limit, 27-29 mg m-3) and 40 mg m-3 (95% confidence limit, 39-41 mg m-3), respectively. Similar correlations were found when the data from the two study periods were analysed separately.

Abstract
To compare two methods of biological monitoring for the evaluation of risk of occupational exposure to n-hexane, we analyze the relationship between environmental exposure to this solvent and urinary excretion of 2,5-hexanedione and n-hexane in exhaled air in 69 workers employed in the shoe industry. Environmental exposure to the solvent was monitored with personal diffusive samplers, which were desorbed with carbon sulfide and analyzed by gas chromatography. To measure 2,5-hexanedione, urine was subjected to acid hydrolysis, separation in octadecyl silane columns, elution with 5% aqueous acetonitrile solution and extraction with dichloromethane, followed by gas chromatography. In exhaled air, n-hexane was measured with a sampling system that permitted concentration of aliquots of end-exhaled air (alveolar air) from one or more exhalations in a tube packed with activated charcoal, which was then desorbed with carbon sulfide and analyzed by gas chromatography. Concentrations of n-hexane in breathing zone air were significantly correlated with urinary concentrations of 2,5-hexanedione (r = 0.88) and with exhaled air n-hexane (r = 0.86); in addition, the two biological indicators correlated significantly (r = 0.70). Analyses in both exhaled air and urine were thus considered useful for biological monitoring of the risk of exposure to n-hexane.

Abstract
Abnormal carnitine distribution in muscle was found in 22 of 77 patients (29%), with mitochondrial myopathy. Furthermore, total (TC) and free (FC) carnitine levels in muscle were lower in patients than in controls (P < 0.01). Muscle long-chain acylcarnitines (LCAC) were significantly increased in these patients (P < 0.01). Muscle carnitine deficiency was found in 31.5% of patients with lipid storage myopathy (LSM) and in 25.6% of patients with ragged-red fibers (RRF). Therefore, carnitine deficiency can be found in patients with mitochondrial myopathy even in the absence of LSM. Muscle levels of TC and FC were lower in patients with respiratory chain defects than in those with normal respiratory chain (P < 0.01). In contrast, LCAC levels were significantly increased (P < 0.05). Carnitine levels did not differ significantly, among patients with different respiratory-chain defects. Consequently, these patients, owing to their biochemical block, reduce progressively the muscle carnitine pool and subsequent LCAC rise, due to long-chain fatty acid (LCFA) accumulation.

Abstract
1. The effects of racemic (rac) ibuprofen and its S(+)- and R(-)-enantiomers on functions of human polymorphonuclear cells (PMN) and platelets were studied in vitro. 2. Rac-ibuprofen inhibited PMN functions (O2- generation, beta-glucuronidase release, LTB4 formation). Similar IC50 values (40-100 microM) were obtained for the S(+)- and R(-)-enantiomers. 3. All forms of ibuprofen inhibited cyclooxygenase-related platelet functions (aggregation, thromboxane formation). The S(+)-enantiomer was about twice as active as the racemate while the R(-)-enantiomer was at least 10-fold less active. This demonstrates that the S(+) is the only cyclooxygenase inhibitory component of the racemate. 4. The concentrations of rac-ibuprofen in PMN and platelets were similar to those in the incubation medium and represented equal concentrations of the enantiomers. This indicates that neither interconversion nor tissue accumulation of the compounds occurred. 5. These data indicate that antineutrophil effects of ibuprofen on human PMN are independent of cyclooxygenase inhibition. Therefore, R(-)-ibuprofen may be superior to the S(+)-isomer for the treatment of PMN-dependent inflammatory diseases. However, effective free drug concentrations may not be obtained in vivo.

Abstract
OBJECTIVE We studied the effect of 1.5% isoflurane end expiratory fraction on arterial oxygenation and on systemic and pulmonary hemodynamics during nonsurgical single lung ventilation. MATERIAL AND METHODS The study includes 6 patients undergoing surgical thoracotomy. In all cases a double lumen endotracheal tube was inserted and pulmonary ventilation was performed with a FiO2 = 1. Patients were placed on lateral decubitus position. The following variables were measured: mean arterial pressure (MAP), mean pulmonary artery pressure (MPAP), central venous pressure (CVP), capillary pulmonary pressure (CPP), cardiac output (CO), and Qs/Qt. Measurements were taken at three different situations. The first was done under bilateral pulmonary ventilation and intravenous anesthesia with thiopental, fentanyl, and diazepam. The nondependent lung was collapsed by means of a selective ventilation of the dependent lung, and the second series of measurements was done 20 min after intravenous anesthesia. The third block of data was obtained after 15 min of respiratory ventilation with 1.5% isoflurane. RESULTS Single lung ventilation induced a significant decrease of Pa O2 (379 +/- 96 mmHg vs 208 +/- 93 mmHg) and a significant increase in Qs/Qt (20 +/- 8% vs 30 +/- 10%). However, during isoflurane ventilation there were no significant changes in PaO2 (208 +/- 93 mmHg vs 204 +/- 94 mmHg) nor in Qs/Qt (30 +/- 10 vs 28 +/- 8). Isoflurane elicited a significant decrease of the CO, whereas MPAP, RVS, and PvO2 did not show significant variations. CONCLUSIONS We conclude that 1.5% isoflurane end expiratory concentrations did not significantly affect pulmonary oxygenation during single lung ventilation.

Abstract
This study compares biological activities of racemic ibuprofen (rac-IBU) and its S(+) and R(-) enantiomeres in human platelet and polymorphonuclear cells (PMN). Rac-IBU inhibited cyclooxygenase-related platelet functions (aggregation, thromboxane (TX) B2 formation) in vitro, the S-(+) enantiomer being 40-100-times more active than the R-(-) form. rac-IBU also inhibited PMN functions (O2- generation, beta-glucuronidase release). These effects in PMN were not stereospecific. The data suggest cyclooxygenase-independent actions of ibuprofen in human PMN which may contribute to its antiinflammatory effects in vivo.
