Role of Tris-CaEDTA as an adjuvant with nebulised tobramycin in cystic fibrosis patients with Pseudomonas aeruginosa lung infections: A randomised controlled trial.

BACKGROUND: We tested if disrupting iron utilisation by P. aeruginosa by adding the Tris-buffered chelating agent CaEDTA to nebulised tobramycin would enhance bacterial clearance and improve lung function in CF patients. METHODS: In this double-blind, randomised controlled trial, 26 episodes (25 patients) with P. aeruginosa infection admitted to two CF centres for treatment of an acute pulmonary exacerbation were randomly assigned to receive either 75 mg CaEDTA in Tris-buffered saline or placebo (Tris-buffered saline) nebulised in combination with 250 mg tobramycin twice daily for six weeks followed with four week safety follow-up. Primary endpoints were safety, tolerability, and bacterial density of P. aeruginosa. A secondary endpoint was lung function. RESULTS: The study drug was well tolerated with adverse events comparable in both groups. The mean (SD) reduction in sputum P. aeruginosa count (log10 CFU/g) in the CaEDTA vs placebo group was 2·05 (2·57) vs 0·82 (2·71) at two weeks relative to admission (p = 0·39). The mean improvement in ppFEV1 was 16 vs 5 (p = 0·16); 11 vs 2 (p = 0·28); and 6 vs 2 percentage points (p = 0·47) at two, six, and ten weeks in CaEDTA and placebo groups, respectively. CONCLUSIONS: In this pilot study in CF patients, an increase in the reduction of sputum density of P. aeruginosa and an increase in ppFEV1 was observed in the group of patients who received Tris-CaEDTA added to inhaled tobramycin compared to the group who received inhaled tobramycin alone, although these differences were not statistically significant. The treatment was also shown to be safe.

The efficacy of dexketoprofen for migraine attack: A meta-analysis of randomized controlled studies.

BACKGROUND: The efficacy of dexketoprofen for migraine attack remains controversial. We conduct a systematic review and meta-analysis to explore the influence of dexketoprofen supplementation versus placebo on pain control in migraine attack patients. METHODS: We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through March 2019 for randomized controlled trials (RCTs) assessing the effect of dexketoprofen supplementation versus placebo on pain control for migraine attack patients. This meta-analysis is performed using the random-effect model. RESULTS: Five RCTs involving 794 patients are included in the meta-analysis. Overall, compared with control group for migraine attack, dexketoprofen supplementation is associated with substantially increased pain free at 2 hours (RR = 1.90; 95% CI = 1.43-2.53; P < .0001), pain free at 48 hours (RR = 1.63; 95% CI = 1.07-2.49; P = .02), good or excellent treatment (RR = 1.48; 95% CI = 1.24-1.78; P < .0001) and pain relief at 2 hours (RR = 1.80; 95% CI = 1.17-2.77; P = .007), as well as reduced need for rescue drug (RR = 0.64; 95% CI = 0.43-0.94; P = .02), with no significant increase in adverse events (RR = 1.51; 95% CI = 0.87-2.62; P = .14). CONCLUSION: Dexketoprofen supplementation benefits to improve pain control at 48 hours and reduce the need for rescue drug in migraine attack patients.

Intradermal mesotherapy versus systemic therapy in the treatment of musculoskeletal pain: A prospective randomized study.

INTRODUCTION: Acute musculoskeletal injuries are one of the most common painful presentation when admission to the emergency department. The aim of the study is to compare the tenoxicam mesotherapy with intravenous dexketoprofen in pain control in patients with acute musculoskeletal injury. METHODS: This parallel randomized controlled trial was conducted with the patients admitted to the emergency department with musculoskeletal injury. Intravenous dexketoprofen was administered to the control group, and mesotherapy treatment was performed to the other group. Differences between 10th, 30th, 60th and 120th minutes VAS scores and on the admission VAS score, clinically meaningful change in pain intensity, and adverse effect of the procedures were compared among groups. THE RESULTS: The differences in VAS scores and the presence of clinically meaningful change in pain intensity were statistically significantly higher in mesotherapy group than the systemic therapy group in all time periods. During one-week follow-up period, there was no reported adverse effect neither in mesotherapy group nor in the systemic therapy group. CONCLUSIONS: The mesotherapy treatment may be superior than the systemic therapy for pain relief in musculoskeletal injury in short term follow-up in emergency department settings.

Efficacy and safety of motherwort injection add-on therapy to carboprost tromethamine for prevention of post-partum blood loss: A meta-analysis of randomized controlled trials.

Motherwort (YiMuCao), a traditional Chinese herb, has been shown beneficial effects for women's diseases. This meta-analysis aimed to evaluate the efficacy and safety of motherwort injection add-on therapy to carboprost tromethamine for prevention of post-partum blood loss. A systematic literature search was conducted in PubMed, Embase, Cochrane Library, CNKI, VIP and Wanfang from their inception to December 2017. Randomized controlled trials that determined the add-on effects of motherwort injection to carboprost for prevention of post-partum blood loss were eligible. Pooled risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI) were used to summarize the effect sizes. Eight trials including 1276 pregnant women fulfilled the inclusion criteria. Prophylactic use of motherwort injection add-on therapy significantly reduced the post-partum 2 h (MD -127.5 mL; 95% CI -149.13 to -105.88) and 24 h (MD -146.85 mL; 95% CI -179.77 to -113.94) blood loss and incidence of post-partum hemorrhage (RR 0.28; 95% CI 0.17-0.45) than carboprost. Moreover, adjunctive treatment with motherwort injection significantly decreased the length of the third stage of labor (MD -3.41 min; 95% CI -4.33 to -2.49) and duration of lochia (MD -7.13 days; 95% CI -8.49 to -5.76). There was no statistical significant difference in the incidence of adverse events (RR 0.76; 95% CI 0.50-1.16). Prophylactic use of motherwort injection add-on therapy to carboprost tromethamine could reduce post-partum blood loss. However, more well-designed trials are necessary to confirm the findings of this study due to the methodological flaws of the included trials.

[Issues of spectrum and local sensitivity of E. coli in female patients with acute uncomplicated lower urinary tract infection a review of M. Seitz study and own observations].

RELEVANCE: Acute uncomplicated lower urinary tract infections (AULUTI) are one of the most common diseases in urological practice. The management of cystitis is commonly based on antibacterial therapy. Despite the high efficiency, inadequate prescription of antibiotics leads to an increase in microorganisms resistance. In light of these matters, the selection of antibacterial agents to which the sensitivity of bacteria is the highest is becoming increasingly challenging. AIM: To estimate the spectrum and local sensitivity of E. coli in patients with AULUTI. MATERIALS AND METHODS: The present study analyzed the results of bacterial culture sampled from 45 patients with AULUTI. The mean age of the patients was 44+/-17 years. All bacterial cultures were obtained in out-patient settings in the framework of a multicenter initiative study on the prevention of recurrent AULUTI with d-mannose. RESULTS: Microbiological studies of the urine of patients with AULUTI revealed the growth of E. coli in concentrations ranging from 104 to 107 CFU/ml. Assessment of sensitivity demonstrated 100% sensitivity of Escherichia coli to fosfomycin trometamol. CONCLUSION: According to the findings of microbiological studies, the patients with the AULUTI retain the highest sensitivity level of E.coli to phosphomycin trometamol, which allows it to be used as a first-line drug.

Multimodal analgesia in moderate-to-severe pain: a role for a new fixed combination of dexketoprofen and tramadol.

BACKGROUND: Untreated and under-treated pain represent one of the most pervasive health problems, which is worsening as the population ages and accrues risk for pain. Multiple treatment options are available, most of which have one mechanism of action, and cannot be prescribed at unlimited doses due to the ceiling of efficacy and/or safety concerns. Another limitation of single-agent analgesia is that, in general, pain is due to multiple causes. Combining drugs from different classes, with different and complementary mechanism(s) of action, provides a better opportunity for effective analgesia at reduced doses of individual agents. Therefore, there is a potential reduction of adverse events, often dose-related. Analgesic combinations are recommended by several organizations and are used in clinical practice. Provided the two agents are combined in a fixed-dose ratio, the resulting medication may offer advantages over extemporaneous combinations. CONCLUSIONS: Dexketoprofen/tramadol (25 mg/75 mg) is a new oral fixed-dose combination offering a comprehensive multimodal approach to moderate-to-severe acute pain that encompasses central analgesic action, peripheral analgesic effect and anti-inflammatory activity, together with a good tolerability profile. The analgesic efficacy of dexketoprofen/tramadol combination is complemented by a favorable pharmacokinetic and pharmacodynamic profile, characterized by rapid onset and long duration of action. This has been well documented in both somatic- and visceral-pain human models. This review discusses the available clinical evidence and the future possible applications of dexketoprofen/tramadol fixed-dose combination that may play an important role in the management of moderate-to-severe acute pain.

Postarthroscopy analgesia using intraarticular levobupivacaine and intravenous dexketoprofen trometamol.

PURPOSE: The aim of this prospective study was to determine the efficacy of intraarticular levobupivacaine with and without intravenous dexketoprofen trometamol for postarthroscopy analgesia. METHODS: Sixty patients who underwent arthroscopic knee surgery were randomly assigned to three treatment groups. When the surgical procedure was completed, patients received the following treatments: group I (n = 20) patients received 20 mL intraarticular normal saline and 2 mL intravenous dexketoprofen trometamol (50 mg); group II (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous normal saline; and group III (n = 20) patients received 20 mL intraarticular 0.5 % levobupivacaine (100 mg) and 2 mL intravenous dexketoprofen trometamol (50 mg). The visual analogue scale (VAS) was used, and the total analgesic consumption was assessed at 1, 2, 4, 6, 12, and 24 h post-operatively. RESULTS: The VAS scores at 1, 2, 4, 6, 12, and 24 h post-operatively were significantly increased in group I and group II compared with group III (p < 0.05). The average VAS score during the first 24 h post-operatively was significantly lower in group III than in group I and group II (p < 0.001). Total meperidine consumption was significantly lower in group III than in groups I and II (p < 0.001). CONCLUSION: Intraarticular levobupivacaine with adjuvant intravenous dexketoprofen trometamol administration provided better pain relief and less analgesic requirement after arthroscopic knee surgery during the first 24 h than that induced by dexketoprofen alone or levobupivacaine intraarticular alone. LEVEL OF EVIDENCE: II.

Factors affecting the success of resynchronization protocols with or without progesterone supplementation in dairy cows.

The objective of this study was to investigate factors that influence the success of resynchronization protocols for bovines with and without progesterone supplementation. Cow synchronized and not found pregnant were randomly assigned to two resynchronization protocols: ovsynch without progesterone (P4) supplementation (n = 66) or with exogenous P4 administered from Days 0 to 7 (n = 67). Progesterone levels were measured on Days 0 and 7 of these protocols as well as 4 and 5 days post-insemination. Progesterone supplementation raised the P4 levels on Day 7 (p < 0.05), but had no overall effect on resynchronization rates (RRs) or pregnancy per artificial insemination (P/AI). However, cows with Body Condition Score (BCS) > 3.5 had increased P/AI values while cows with BCS < 2.75 had decreased P/AI rates after P4 supplementation. Primiparous cows had higher P4 values on Day 7 than pluriparous animals (p = 0.04) and tended to have higher RRs (p = 0.06). Results of this study indicate that progesterone supplementation in resynchronization protocols has minimal effects on outcomes. Parity had an effect on the levels of circulating progesterone at initiation of the protocol, which in turn influenced the RR.

Comparison of the effect of lidocaine adding dexketoprofen and paracetamol in intravenous regional anesthesia.

OBJECTIVE: Comparison of dexketoprofen and paracetamol added to the lidocaine in Regional Intravenous Anesthesia in terms of hemodynamic effects, motor and sensorial block onset times, intraoperative VAS values, and analgesia requirements. METHOD: The files of 73 patients between 18 and 65 years old in the ASA I-II risk group who underwent hand and forearm surgery were analyzed and 60 patients were included in the study. Patients were divided into 3 groups: Group D (n = 20), 3 mg/kg 2% lidocaine and 50 mg/2 mL dexketoprofen trometamol; Group P (n = 20), 3 mg/kg 2% lidocaine and 3 mg/kg paracetamol; Group K (n = 20), 3 mg/kg 2% lidocaine. Demographic data, motor and sensorial block times, heart rate, mean blood pressure, VAS values, and intraoperative and postoperative analgesia requirements were recorded. RESULTS: Sensorial and motor block onset durations of Group K were significantly longer than other groups. Motor block termination duration was found to be significantly longer in Group D than in Group K. VAS values of Group K were found higher than other groups. There was no significant difference in VAS values between Group D and Group P. Analgesia requirement was found to be significantly more in Group K than in Group P. There was no significant difference between the groups in terms of heart rates and mean arterial pressures. CONCLUSION: We concluded that the addition of 3 mg/kg paracetamol and 50 mg dexketoprofen to lidocaine as adjuvant in Regional Intravenous Anesthesia applied for hand and/or forearm surgery created a significant difference clinically.

Can the addition of a paracervical block to systemic or local analgesics improve the pain perceived by the patient during hysterosalpingography?

The aim of the present study was to investigate whether the addition of a paracervical block to local intrauterine anaesthesia or the use of an intramuscular non-steroidal anti-inflammatory drug was effective for pain control during and at 30 min after hysterosalpingography (HSG). A total of 120 patients undergoing hysterosalpingography were randomised into four groups. Patients received intramuscular dexketoprofen trometamol with or without a paracervical block or intracavitary lidocaine instillation with or without paracervical block. The primary outcome was the overall pain score from the four stages of the procedure. The lowest pain scores were observed in the patients receiving dexketoprofen trometamol with a paracervical block, whereas the highest pain scores were observed in patients with intracavitary lidocaine instillation without a paracervical block (p = 0.021). No beneficial effect was found when a paracervical block (PCB) was added to either systemic or local analgesics. The combination of intramuscular dexketoprofen and a paracervical block with plain lidocaine produced the best pain relief during the three specified steps and at up to 30 min after the HSG procedure.

Estudio comparativo aleatorizado para la evaluación de un nuevo esquema terapéutico de fosfomicina trometamol en mujeres posmenopáusicas con infección no complicada del tracto urinario inferior / Randomized Comparative Study for the Assessment of a New Therapeutic Schedule of Fosfomycin Trometamol in Postmenopausal Women with Uncomplicated Lower Urinary Tract Infection

Objetivos: Comparación de 2 regímenes terapéuticos en términos de erradicación bacteriana para mujeres posmenopáusicas con cistitis aguda no complicada, que completan el tratamiento antibiótico. Material y método: Estudio multicéntrico prospectivo aleatorizado y controlado entre 2 pautas de antibioterapia corta: fosfomicina trometamol (FMT) 3g, 2 dosis cada 72h y ciprofloxacino 250mg cada 12h durante 3 días. Se incluyeron 118 mujeres posmenopáusicas en el estudio. Se practicó cultivo de orina inicial para conocer el microorganismo responsable y la sensibilidad al tratamiento, y se repitió 5-7 días y 4 semanas después del tratamiento, para evaluar erradicación bacteriana. También se evaluaron los síntomas clínicos y la seguridad del tratamiento. Resultados: Existen datos microbiológicos al inicio del tratamiento en 82 mujeres (69,49%), 27 no presentaron cultivo positivo en la primera visita (30,51%), completaron todos los requisitos del protocolo 76 (64,41%) y se recogieron los efectos adversos del tratamiento en 113 (95,76%) de los pacientes inicialmente incluidos en el estudio. Los gérmenes aislados con mayor frecuencia fueron Escherichia coli (E. coli) (76,83%), Klebsiella pneumoniae (K. pneumoniae) (7,32%), Proteus mirabilis (P. mirabilis) (4,89%) y Enterococo sp. (3,66%). En términos de eficacia no se detectaron diferencias en la proporción de pacientes que consiguieron erradicación bacteriana entre los 2 brazos del estudio: 62,16% de los pacientes que recibieron FMT y 58,97% de los tratados con ciprofloxacino (Chi-cuadrado, p=0,78). La proporción de pacientes que consiguieron curación clínica fue también parecido (86,49% para FMT y 82,05% para ciprofloxacino; Chi-cuadrado, p=0,59). Estos resultados indican una eficacia parecida de ambos antibióticos en el tratamiento de la infección urinaria de vías bajas no complicada en mujeres posmenopáusicas. En lo que respecta a los datos de seguridad la proporción de efectos adversos globales asociados a los tratamientos fueron 3,45% para FMT y 9,09% para ciprofloxacino. La adherencia al tratamiento fue del 100% para FMT y del 83,64% para ciprofloxacino. Conclusiones: La FMT administrada en dosis de 3g cada 72h (2 dosis total) y ciprofloxacino en dosis de 250mg cada 12h durante 3 días (6 dosis total) tienen un perfil de eficacia equiparable en la infección del tracto urinario inferior de la mujer posmenopáusica que completa apropiadamente el tratamiento, con una seguridad también equiparable, la FMT presenta un mejor perfil de sensibilidad antimicrobiana y mejor tasa de adherencia terapéutica (AU)

Objectives: To compare two therapeutic regimes in terms of bacterial eradication of post-menopausal with uncomplicated acute cystitis who complete antibiotic treatment. Materials and method: A multicenter, randomized, prospective and controlled study between two short antibiotic regimes: fosfomycin trometamol (FMT) 3g, 2 doses separated by 72hours and ciprofloxacin 250mg every 12hours for 3 days. A total of 118 post-menopausal women were enrolled in the study. They underwent an initial urine culture to know the responsible microorganism and susceptibility to treatment. This was repeated 5-7 days and 4 weeks after the treatment to evaluate bacterial eradication. Clinical symptoms and treatment safety were also evaluated. Results: There were microbiological data at the onset of the treatment in 82 women (69.49%). Of these, 27 did not have positive culture at the first visit (30.51%), 76 (64.41%) fulfilled all the protocol requirements and adverse effects from the treatment were collected in 113 (95.76%) of the patients enrolled in the study. The germs isolated most frequently were Escherichia coli (E. coli) (76.83%), Klebsiella pneumoniae (K. pneumoniae) (7.32%), Proteus mirabilis (P. mirabilis) (4.89%) and Enterococo sp. (3.66%). In terms of efficacy, no differences were detected in the proportion of patients who achieved bacterial eradication between the two study arms: 62.16% of the patients who received FMT and 58.97% of those treated with ciprofloxacin (chi-square, p=0.78). The proportion of patients who achieved clinical cure was also similar (86.49% for FMT and 82.05% for ciprofloxacin; square, p=0.59). These results indicate similar efficacy of both antibiotics in the treatment of uncomplicated lower tract urinary infection in post-menopausal women. In regards to safety data, the proportion of global adverse effects associated to the treatments was 3.45% for FMT and 9.09% for ciprofloxacin. Treatment compliance was 100% for FMT and 83.64% for ciprofloxacin. Conclusions: The FMT administered at a dose of 3g every 72hours (2 total doses) and ciprofloxacin at a dose of 250mg every 12hours during 3 days (6 total doses) have a comparable efficacy profile in lower tract urinary infection in post-menopausal women who adequately comply with the treatment, also having comparable safety. The FMT has a better antimicrobial susceptibility profile and better rate of treatment compliance (AU)

[Treatment and metaphylaxis of gout complicated by nephropathy and urolithiasis].

The evaluation of clinical efficacy of combined treatment and metaphylaxis in 58 patients with gout complicated by nephropathy and urolithiasis was performed. The study included 41 (71%) men and 27 (29%) women aged 44 to 88 years (mean age - 58 +/- 7 years). All patients received parenteral therapy with trometamol H, 5 -10 infusion for the course, an average of 7 infusions. For the metaphylaxis, all patients received biologically active supplement urisan 2 tablets 2 times a day during next three months against the background of drug therapy. Findings indicate a high clinical efficacy of the trometamol H in the combined treatment of patients with gout, complicated by nephropathy and urolithiasis, considering that improvement of renal function, microcirculation in the renal parenchyma, increased glomerular filtration rate, normalization of nitrogenous wastes levels, partial or complete dissolution of concretions of the kidneys, a significant decrease in the tophs size, an increase in motor activity were observed, which ultimately improves the quality of life for these patients. Metaphylaxis using urisan for 3 months on a background of traditional therapy contributed to a stable normalization of blood uric acid levels, which prevented the exacerbation of underlying disease and recurrent stone formation. These data allow to recommend reducing the dose of traditional anti-gout drugs and conducting repeated course of metaphylaxis with the urisan after 5-6 months during 3 months.

Antinociceptive and anti-exudative synergism between dexketoprofen and tramadol in a model of inflammatory pain in mice.

Preclinical studies have demonstrated antinociceptive synergism between dexketoprofen (DEX) and tramadol (TRM) in acute animal models of nociception. The aim of the present study was to investigate the type of interaction between DEX and TRM in a chronic musculoskeletal pain model in mice, which fairly replicates the characteristics of chronic osteoarticular pain in humans. Inflammation was induced by a subplantar injection of complete Freund's adjuvant (CFA) in male CF1 mice. Nociceptive thresholds were evaluated using the hot plate, the nocifensive spontaneous behavior and the acetone tests, while plasma extravasation (PE) was assessed with Evan's blue. We used the following experimental groups: control (no inflammation), acute (1 day after CFA injection), and chronic inflammation (7 days after CFA). Dose-response curves for DEX and TRM, individually and combined in a 1 : 1 proportion based on their potency were obtained, and the doses that produced a 50% inhibition calculated. The isobolographic analysis revealed that in all groups of study (no inflammation, acute, and chronic inflammation), the combination of DEX : TRM was synergistic, for both the inhibition of nociception and the PE. The results suggest that the DEX : TRM (1 : 1) combination could be useful in the management of acute and chronic inflammatory musculoskeletal pains in humans; in addition, the synergistic interaction between the drugs observed both during acute and chronic inflammation suggests that less doses would be required of each drug to obtain effective analgesia.

The analgesic effect of dexketoprofen when added to lidocaine for intravenous regional anaesthesia: a prospective, randomized, placebo-controlled study.

This prospective, randomized, placebo-controlled study evaluated the effects of dexketoprofen as an adjunct to lidocaine in intravenous regional anaesthesia (IVRA) or as a supplemental intravenous (i.v.) analgesic. Patients scheduled for elective hand or forearm soft-tissue surgery were randomly divided into three groups. All 45 patients received 0.5% lidocaine as IVRA. Dexketoprofen was given either i.v. or added into the IVRA solution and the control group received an equal volume of saline both i.v. and as part of the IVRA. The times of sensory and motor block onset, recovery time and postoperative analgesic consumption were recorded. Compared with controls, the addition of dexketoprofen to the IVRA solution resulted in more rapid onset of sensory and motor block, longer recovery time, decreased intra- and postoperative pain scores and decreased paracetamol use. It is concluded that coadministration of dexketoprofen with lidocaine in IVRA improves anaesthetic block and decreases postoperative analgesic requirements.

Comparison of oral nonsteroidal analgesic and intrauterine local anesthetic for pain relief in uterine fractional curettage: a randomized, double-blind, placebo-controlled trial.

OBJECTIVE: We sought to investigate the analgesic efficacy of oral dexketoprofen trometamol and intrauterine lidocaine in patients undergoing fractional curettage. STUDY DESIGN: A randomized, double-blind, placebo-controlled trial was conducted on 111 women. Subjects were randomly assigned into 4 groups to receive either 25 mg of dexketoprofen or similar-appearing placebo tablets and either 5 mL intrauterine 2% lidocaine or saline. The main outcome measure was the intensity of pain measured by a 10-cm visual analog scale. Pain scoring was performed prior to, during, and 30 minutes after the procedure. RESULTS: No statistically significant difference was found among the mean pain scores of women during the procedure in the dexketoprofen and saline, placebo and lidocaine, and dexketoprofen and lidocaine groups. The mean pain scores in all 3 groups revealed significant reduction when compared with placebo and saline combination (P = .001). CONCLUSION: Administration of intrauterine lidocaine or oral dexketoprofen appears to be effective in relieving fractional curettage associated pain. However, a combination of them does not work better in further reduction of pain.

In vitro activity of an ear rinse containing tromethamine, EDTA, benzyl alcohol and 0.1% ketoconazole on Malassezia organisms from dogs with otitis externa.

The purpose of this study was to evaluate the in vitro activity of an ear rinse containing tromethamine, EDTA, benzyl alcohol and 0.1% ketoconazole in purified water on Malassezia organisms from dogs with otitis externa. Malassezia organisms were collected from ear swab samples from the external ear canal of 19 dogs with otitis externa plus one control strain of Malassezia pachydermatis. Three test solutions were evaluated: ER (EDTA, tromethamine, benzyl alcohol), ER + keto (EDTA, tromethamine, benzyl alcohol, ketoconazole), and H2O (purified water). Ten-millilitre aliquots of each test solution was transferred into 20 tubes and inoculated with one of the isolates (1 tube per isolate: 19 clinical and 1 control strain). Samples were retrieved from each tube at five time points (0, 15, 30, 45 and 60 min), transferred to Petri dishes, mixed with Sabouraud dextrose agar supplemented with 0.5% Tween 80 and incubated. Following incubation, the plates were examined for growth and colonies counted as colony-forming units per millilitre. The data were analysed using a repeated measures analysis, with pair-wise comparisons of solution-time combinations. There was a significant reduction in Malassezia growth in ER + keto at all time points (P < 0.0001) compared to time zero. Neither ER nor H2O had any effect on the growth of Malassezia. ER + keto was significantly more effective in reducing Malassezia growth (P < 0.0001) at all time points compared to both ER and H2O. ER + keto may be useful in the treatment of Malassezia otitis externa. Future studies should be performed to evaluate the in vivo efficacy of ER + keto as treatment for otic infections caused by Malassezia.

Fosfomycin tromethamine in uncomplicated urinary tract infections: a clinical study.

The aim of our study was to verify if the empiric therapy with a single dose of 3 g fosfomycin tromethamine in patients with uncomplicated urinary tract infections (UTIs) was able to clinically resolveand to microbiologically eradicate the infection. A total of 387 out of the 400 patients (274 cases with acute and 113 cases with recurrent uncomplicated UTIs) were enrolled in the clinical study. Clinical and microbiological assessments were performed before and at 8-10 days after the administration. At follow-up high clinical recovery (88.9%) and bacteriological (94.9%) eradication rates were achieved. Gastrointestinal side effects were found in only 4.3% of patients. In conclusion, a single-dose administration regimen of fosfomycin tromethamine should be encouraged as a first choice of drug therapy for uncomplicated UTIs.

Ouabain at nanomolar concentration promotes synthesis and release of angiotensin II from the endothelium of the tail vascular bed of spontaneously hypertensive rats.

The effects of 1 nM ouabain (OUA) on the contractile actions of phenylephrine (PHE, 0.001-100 microg) and functional activity of the sodium pump (NKA) in isolated-perfused tail vascular beds from WKY and SHR were investigated. In preparations from SHR, perfusion with OUA in the presence of endothelium (E+) increased the sensitivity (pED50) of PHE (before: 2.14 +/- 0.06 versus after: 2.47 +/- 0.07; P < 0.05) without altering the maximal response (Emax). After endothelial damage, OUA reduced the Emax of PHE in SHR (before: 350 +/- 29 versus after: 293 +/- 25 mm Hg; P < 0.05). In SHR/E+, pretreatment with losartan (10 microM) or enalaprilat (1 microM) prevented the increased sensitivity to PHE induced by OUA. OUA increased NKA activity in SHR/E+ (before: 45 +/- 6 versus after: 58 +/- 5%, P < 0.05). Losartan (10 mg/Kg, i.v.) also abolished the increment in systolic and diastolic blood pressure induced by OUA (0.18 microg/Kg, i.v.) in anesthetized SHR. OUA did not alter the actions of PHE in either anesthetized WKY rats or vascular preparations. Results suggest that 1 nM OUA increased the vascular reactivity to PHE only in SHR/E+. This effect is mediated by OUA-induced activation of endothelial angiotensin converting enzyme that promotes the local formation of angiotensin II, which sensitizes the vascular smooth muscle to the actions of PHE.

Response to repeated equal doses of epinephrine during cardiopulmonary resuscitation in dogs.

STUDY OBJECTIVE: Advanced cardiac life support (ACLS) guidelines recommend a 3- to 5-minute interval between repeated doses of epinephrine. This recommendation does not take into account the dose of epinephrine used, and only very limited data exist regarding the hemodynamic responses to repeated "high" doses of epinephrine. The objective of this study was to analyze the hemodynamic responses to repeated, equal, high doses of epinephrine administered during cardiopulmonary resuscitation (CPR) in a canine model of ventricular fibrillation (VF). METHODS: This study used a secondary analysis of data collected in a prospective, randomized study, primarily designed to assess the effects of acid buffers in a canine model of cardiac arrest. VF was electrically induced. After 10 minutes, CPR was initiated, including ventilation with FIO(2)=1.0, external chest compressions, administration of epinephrine (0.1 mg/kg repeated every 5 minutes) and defibrillation. Animals were randomized to receive either NaHCO(3), Carbicarb, tromethamine (THAM), or NaCl. The hemodynamic variables were sampled from each experiment's paper chart at 1-minute intervals, and the responses to the first 4 doses of epinephrine were compared. RESULTS: Thirty-six animals (9 in each buffer group) were included in this analysis. Systolic, diastolic, and coronary perfusion pressures increased steeply (by 100%, 130%, and 190%, respectively) only after the first epinephrine dose. These pressures peaked at 2 to 3 minutes and decreased only slightly and insignificantly during the rest of the 5-minute interval, until the next epinephrine dose. No further significant increases in arterial pressures were observed in response to the next 3 doses of epinephrine, administered 5 minutes apart. CONCLUSION: The hemodynamic effects of high-dose epinephrine (0.1 mg/kg) during CPR appear to last longer than 5 minutes. Therefore, longer intervals between doses may be justified with high doses of epinephrine.
