Abstract
BACKGROUND The aim of the study was to evaluate the efficacy of nicorandil and alprostadil on myocardial protection in patients undergoing elective percutaneous coronary intervention (PCI). METHODS In this prospective, single-blinded, randomized controlled study, 90 consecutive patients scheduled for elective PCI for de novo coronary lesions were assigned to the nicorandil, alprostadil, and nitroglycerin groups in a 1:1:1 ratio. Drugs were administered intracoronary via a targeted perfusion microcatheter. The primary endpoint was the thrombolysis in myocardial infarction (TIMI) myocardial perfusion frame count (TMPFC). Additionally, the corrected TIMI frame count (cTFC), TIMI myocardial perfusion grade (TMPG), and incidence of periprocedural myocardial injury (PMI) were assessed. RESULTS Both nicorandil and alprostadil were significantly effective in reducing TMPFC (114.6 ± 33.7 vs 93.4 ± 30.9, P = .016; 114.3 ± 34.3 vs 94.7 ± 33.3, P = .029, respectively). Similar findings were observed in the improvement of cTFC (20.3 ± 10.5 vs 13.5 ± 5.0, P = .003; 20.2 ± 7.4 vs 15.2 ± 5.2, P = .003, respectively) and percentage of TMPG 3 (100% vs 82.8%, P = .052; 83.3% vs 96.7%, P = .196, respectively); whereas, nitroglycerin produced a limited effect on TMPFC (114.4 ± 30.9 vs 112.1 ± 31.9, P = .739), cTFC (19.4 ± 7.2 vs 19.3 ± 7.2, P = .936), and percentage of TMPG 3 (86.7% vs 86.7%, P = 1.000). No significant difference was found in the incidence of PMI (16.7% vs 16.0% vs 27.6%, P = .537), though it was comparatively lower in the nicorandil and alprostadil groups. Furthermore, the intracoronary administration of nicorandil and alprostadil had a mild effect on blood pressure and heart rate. CONCLUSIONS The intracoronary administration of nicorandil and alprostadil via a targeted perfusion microcatheter was more effective in improving myocardial perfusion in patients undergoing elective PCI than nitroglycerin.

Abstract
ABSTRACT Lumbar spinal stenosis is one of the most commonly diagnosed spinal disorders worldwide and remains a major cause for surgery in older adults. Lumbar spinal stenosis is clinically defined as a progressive degenerative disorder with low back pain and associated neurogenic intermittent claudication. Conservative and surgical management of lumbar spinal stenosis has been shown to be minimally effective on its symptoms. A treatment option that has not been investigated in the United States is the utilization of prostaglandin E1 analogs, which have been used primarily in Japan for the treatment of lumbar spinal stenosis since the 1980s. The vasodilatory and antiplatelet aggregation effects of prostaglandin E1 presumably improve symptoms of lumbar spinal stenosis by increasing blood flow to the spinal nerve roots. This brief report examines the potential vascular pathology of lumbar spinal stenosis, reviews evidence on the use of prostaglandin E1 analog limaprost in Japan for lumbar spinal stenosis, and briefly discusses misoprostol as a possible alternative in the United States. The studies summarized in this report suggest that prostaglandin E1 analogs may provide benefit as a conservative treatment option for patients with lumbar spinal stenosis. However, higher-quality studies conducted in the United States and comparison with other currently used conservative treatments are required before it can be recommended for routine clinical use.

Abstract
BACKGROUND The pathogenesis of diabetic peripheral neuropathy is more complex and it is not yet clear, but studies have shown that microangiopathy and oxidative stress responses are closely related to their pathogenesis. At present, the treatment of improving microcirculation and antioxidant stress is mainly used in clinical. Alprostadil is a commonly used vasodilator, and alpha lipoic acid is an antioxidant, which can effectively reduce oxidative stress responses and delay the progression of diabetes mellitus and its complications. However, there is a lack of evidence-based medical evidence for alprostadil combined with alpha lipoic acid in the treatment of diabetic peripheral neuropathy, and this article aims to understand the clinical effectiveness and safety of alprostadil combined with alpha lipoic acid in the treatment of diabetic peripheral neuropath by a meta-analysis of published randomized controlled trials. METHODS In this study, we obtain the relevant literature by retrieving 8 electronic databases, including PubMed, EMBASE, Web of Science, the Cochrane Library, CBM, CNKI, VIP, and WanFang Database. Retrieving a randomized controlled study of alprostadil combined with alpha lipoic acid in the treatment of diabetic peripheral neuropath, while the language of the literature is restricted and it only includes Chinese and English literature. For the publication of literature, the time is from the beginning of the database to August 31, 2020. In the English database, using the retrieval method of subject word combined free word. The two researchers read the titles and abstracts of all the literature independently based on the inclusion and exclusion criteria. If it cannot be determined whether the literature is included by reading the title and abstract, then download and read the full text of the literature. If there is a dispute between the two researchers about the literature, so it should discuss the dispute with the third researcher in order to reach a conclusion. Using the bias risk assessment tool of randomized controlled trials in Cochrane systematic review to evaluate the bias risk of the included literature; Using RevMan 5.3 software to conduct statistical analysis; Using funnel plot analysis to analyze the situation of literature publication bias. RESULTS This study will provide a high-quality evidence on the effects of hydrolyzed protein formula milk on gastrointestinal diseases and physical development of premature infants. CONCLUSION This study will draw reliable evidence-based medical evidence for alprostadil combined with Alpha lipoic acid in the treatment of diabetic peripheral neuropathy, thus providing help for the clinical treatment of diabetic peripheral neuropathy.

Abstract
RATIONALE Erectile dysfunction (ED) and Peyronie's disease (PD) are conditions commonly observed in andrology. Despite the surgical refinement and the technical improvement in this field, even in expert hands, detrimental consequences have been reported and it can be related to patient's comorbidities or misconduct in the postoperative period. In this article we report anecdotal cases of severe complications following penile surgery for ED and PD in high volume centers, describe the strategies adopted to treat it and discuss the options that would have helped preventing these events. PATIENTS' CONCERNS The first case describes a patient with history of ED and PD causing penile shortening and a slight dorsal deviation of penile shaft. In the second case it is described a corporeal necrosis and urethral fistula following inflatable penile prosthesis implant. In the last case it is described the migration of reservoir into the abdomen after inflatable penile prosthesis implantation post-radical prostatectomy. DIAGNOSIS All 3 patients were investigated with a penile doppler ultrasound with PGE1 intracorporeal injection for ED and PD diagnosis. An abdominal computed tomography scan and magnetic resonance imaging were ordered for patient of case three. INTERVENTIONS The patients underwent different combined procedures depending on the case and including: glansectomy, penile prosthesis implantation associated with a penile elongation with double dorsal-ventral patch graft ("sliding technique"), penile urethroplasty with buccal mucosa graft, and laparotomy for reservoir removal. OUTCOMES No further serious complications were reported after the procedures described. LESSONS Penile surgery in patients with concomitant PD and systemic comorbidities can be at high risk of complications. As shown in this series there are possible dramatic evolution of these complications that may cause irreversible consequences to the patient. For this reason, a dedicated surgical and nursing team is necessary to reduce the chances that it happens. When this event occurs, a team trained in their management can improve the patient outcome.

Abstract
BACKGROUND Papaverine is used to induce maximal hyperemia for index of coronary microcirculatory resistance (IMR) measurement in animal experiments, although it can lead to polymorphic ventricular tachycardia and ventricular fibrillation. OBJECTIVES This study investigated the effect of an intracoronary (IC) bolus of high adenosine triphosphate (ATP) and nicorandil doses for IMR measurement and explored the possibility of inducing maximal hyperemia with an IC alprostadil bolus. MATERIAL AND METHODS Index of coronary microcirculatory resistance was measured in a hyperemic state induced by 7 experimental conditions in 21 pigs (IC bolus of papaverine (18 mg), ATP (40 μg, 80 μg, 160 μg, and 240 μg), and nicorandil (2 mg and 4 mg)). The 7 conditions were induced sequentially, and the average IMR was calculated. Because of the long-term hyperemic condition in the pilot experiments, the IMR was measured 1, 3, 5, 8, and 10 min after an IC bolus of alprostadil (10 μg) in another 7 pigs. RESULTS The IMR induced by 240 μg of ATP or 4 mg of nicorandil was not significantly different from that induced by 18 mg of papaverine (both p > 0.05). A strong linear correlation was observed between IMRs with papaverine (18 mg) and nicorandil (4 mg) (R2 = 0.936, p < 0.001) and with papaverine (18 mg) and ATP (240 μg) (R2 = 0.838, p < 0.05). The IC bolus of nicorandil (4 mg) produced the smallest changes, whereas papaverine caused the most significant changes in mean blood pressure and heart rate (p < 0.05). Tachypnea and transient ST depression were more common with increasing ATP dosages (especially 240 μg). Alprostadil (5 min) yielded a significant hyperemic response but reduced baseline blood pressure by almost 40% for a long time. CONCLUSIONS Intracoronary bolus administration of 4 mg of nicorandil was better than 18 mg of papaverine or 240 μg of ATP for induction of maximal hyperemia and IMR measurement in a pig model, whereas alprostadil was not suitable for IMR measurement.

Abstract
INTRODUCTION Prostaglandin E1 (PGE1) administered to patients in the immediate post-transplant period has been known to reduce ischemic reperfusion injuries (IRIs), but the effect on IRI of PGE1 administered to the donor is unknown. The purpose of this study was to determine the effect on IRI of PGE1 injected into donor rats during heterotopic heart transplantation. METHODS Genetically identical male Sprague Dawley rats with a body weight of 300-320 g at 8-9 weeks of age were used for the study. Experimental methods were the same in the control (G0, n = 6) and experimental groups (G1, n = 6), but only the donor rats in the experimental group received an intramuscular injection of PGE1 (5 μg/kg) prior to the donor surgery. On day 1 the animals were sacrificed with the removal of the transplanted heart. Histologic analysis was performed in the hematoxylin-eosin-stained slides to assess interstitial edema and neutrophil infiltration by a pathologist. RESULTS Median times of the donor organ procurement, cold ischemia, and warm ischemia were 37, 69, and 35 minutes, respectively, in the G0 group and 38, 76.5, and 33 minutes respectively in G1 group; there were no statistical differences. Heartbeats were observed in the transplanted graft in 2 of the G0 group and 2 of G1 group immediately after heart transplantation, but in all transplanted grafts on day 1 after surgery. Histologic scores for neutrophil infiltration showed significantly lower in the G1 group than in the G0 group. CONCLUSION PGE1 administration to donors in a rat heart transplantation model may significantly reduce IRI.

Abstract
OBJECTIVE To compare the hemodynamic indexes of penile cavernosal arteries in different phases of penile erection and determine the optimal time for color Doppler ultrasonography of the penis. METHODS Forty healthy adult male volunteers with normal erectile function received intracavernous injection of 10 μg Alprostadil together with visual and auditory stimuli. Within the next 30 minutes, we monitored dynamically the blood flow in the bilateral penile cavernosal arteries, and recorded and compared the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) in the phases of latency, tumescence, full erection and rigid erection. RESULTS Fourteen of the subjects experienced latency, tumescence and full erection only, but failed to achieve rigid erection. PSV and RI were significantly higher while EDV remarkably lower in the tumescence and full erection phases than in the latency phase (all P < 0.01). Statistically significant differences were observed between the tumescence and full erection phases in EDV and RI (both P < 0.01) but not in PSV (P > 0.05). Among the 26 males that achieved rigid erection, PSV, EDV and RI showed significant differences between the full and rigid erection phases (all P < 0.01), but not between the left and right cavernosal arteries in the same phase (P > 0.05). CONCLUSIONS The blood flow in the penile cavernosal arteries changes dynamically in the process of penile erection, and the hemodynamic indexes obtained in the full erection phase can better reflect the function of penile cavernous vessels.

Abstract
BACKGROUND AND OBJECTIVE To evaluate the efficacy of systemic prostaglandin E1 (PGE1) infusion within the first 24 hours of acute central retinal artery occlusion (CRAO). PATIENTS AND METHODS Best corrected visual acuity (BCVA) was analyzed in a case series of six eyes from six patients (mean age: 69.33 years) with acute CRAO who were treated with twice-daily intravenous infusion of 40 μg PGE1. Therapy continued until the patient no longer experienced visual acuity improvements for 24 hours. RESULTS Average time to presentation was 8.33 hours (range: 2 to 12 hours). The logMAR BCVA at presentation was 2.73. BCVA at the final visit 1 month after initial presentation was 1.48 (P = .025). All patients experienced vision improvement. No systemic adverse events were experienced. CONCLUSION Intravenous PGE1 infusion resulted in significant visual improvement in patients presenting with acute CRAO and is well tolerated with few adverse effects.

Abstract
BACKGROUND Prostaglandin E1 (P) or methylcobalamin (M) treatment has been suggested as a therapeutic approach for diabetic peripheral neuropathy (DPN) in many clinical trial reports. However, the combined effects of 2 drugs still remain dubious. OBJECTIVE The aim of this report was to evaluate the efficacy of M plus P (M + P) for the treatment of DPN compared with that of P monotherapy, in order to provide a reference resource for rational drug use. METHODS Randomized controlled trials (RCTs) of M + P for DPN published up to September 2017 were searched. Risk ratio (RR), mean difference (MD), and 95% confidence interval (CI) were calculated and heterogeneity was assessed with the I test. Subgroup and sensitivity analyses were also performed. The outcomes measured were as follows: the clinical efficacy, median motor nerve conduction velocities (MNCV), median sensory nerve conduction velocity (SNCV), peroneal MNCV, peroneal SNCV, and adverse effects. RESULTS Sixteen RCTs with 1136 participants were included. Clinical efficacy of M + P combination therapy was significantly better than P monotherapy (fifteen trials; RR 1.25, 95% CI 1.18-1.32, P < .00001, I = 27%). Compared with P monotherapy, the pooled effects of M + P combination therapy on nerve conduction velocity were (MD 6.29, 95% CI 4.63-7.94, P < .00001, I = 90%) for median MNCV, (MD 5.68, 95% CI 3.53-7.83, P < .00001, I = 94%) for median SNCV, (MD 5.36, 95% CI 3.86-6.87, P < .00001, I = 92%) for peroneal MNCV, (MD 4.62, 95% CI 3.48-5.75, P < .00001, I = 86%) for peroneal SNCV. There were no serious adverse events associated with drug intervention. CONCLUSIONS M + P combination therapy was superior to P monotherapy for improvement of neuropathic symptoms and NCVs in DPN patients. Moreover, no serious adverse events occur in combination therapy.

Abstract
BACKGROUND Despite efforts to preserve the neurovascular bundles with nerve-sparing surgery, erectile dysfunction remains common following radical prostatectomy. Postoperative penile rehabilitation seeks to restore erectile function but results have been conflicting. OBJECTIVES To evaluate the effects of penile rehabilitation strategies in restoring erectile function following radical prostatectomy for prostate cancer. SEARCH METHODS We performed a comprehensive search of multiple databases (CENTRAL, MEDLINE, Embase), the Cochrane Library, Web of Science, clinical trial registries (ClinicalTrials.gov, International Clinical Trials Registry Platform) and a grey literature repository (Grey Literature Report) from their inception through to 3 January 2018. We also searched the reference lists of other relevant publications and abstract proceedings. We applied no language restrictions. SELECTION CRITERIA We included randomised or quasi-randomised trials with a parallel or cross-over design. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodological procedures. Two review authors independently screened the literature, extracted data, assessed risk of bias and rated quality of evidence according to GRADE on a per-outcome basis. Primary outcomes were self-reported potency, erectile function measured by validated questionnaires (with potency defined as an International Index of Erectile Function (IIEF-EF) score of 19 or greater and or an IIEF-5 of score of 17 or greater) and serious adverse events. For all quality of life assessments on a continuous scale, higher values indicated better quality of life. MAIN RESULTS We included eight randomised controlled trials with 1699 participants across three comparisons. This abstract focuses on the primary outcomes of this review only.Scheduled phosphodiesterase type 5 inhibitors (PDE5I) versus placebo or no treatmentScheduled PDE5I may have little or no effect on short-term (up to 12 months) self-reported potency (risk ratio (RR) 1.13, 95% confidence interval (CI) 0.91 to1.41; very low quality evidence), which corresponds to 47 more men with self-reported potency per 1000 (95% CI 33 fewer to 149 more) and short-term erectile function as assessed by a validated instrument (RR 1.11, 95% CI 0.80 to 1.55; very low quality evidence), which corresponds to 28 more men per 1000 (95% CI 50 fewer to 138 more), but we are very uncertain of both of these findings. Scheduled PDE5I may result in fewer serious adverse events compared to placebo (RR 0.32, 95% CI 0.11 to 0.94; low quality evidence), though this does not appear biologically plausible and may represent a chance finding. We are also very uncertain of this finding. We found no long-term (longer than 12 months) data for any of the three primary outcomes.Scheduled PDE5I versus on-demand PDE5I Daily PDE5I appears to result in little to no difference in both short-term and long-term (greater than 12 months) self-reported potency (short term: RR 0.97, 95% CI 0.62 to 1.53; long term: RR 1.00, 95% CI 0.60 to 1.67; both very low quality evidence); this corresponds to nine fewer men with self-reported short-term potency per 1000 (95% CI 119 fewer to 166 more) and zero fewer men with self-reported long-term potency per 1000 (95% CI 153 fewer to 257 more). We are very uncertain of these findings. Daily PDE5I appears to result in little to no difference in short-term and long-term erectile function (short term: RR 1.00, 95% CI 0.65 to 1.55; long term; RR 0.74, 95% CI 0.48 to 1.14; both very-low quality evidence), which corresponds to zero men with short-term erectile dysfunction per 1000 (95% CI 80 fewer to 125 more) and 119 fewer men with long-term erectile dysfunction per 1000 (95% CI 239 fewer to 64 more). We are very uncertain of these findings. Scheduled PDE5I may result in little or no effects on short-term adverse events (RR 0.69 95% CI 0.12 to 4.04; very low quality evidence), which corresponds to seven fewer men with short-term serious adverse events (95% CI 18 fewer to 64 more), but we are very uncertain of these findings. We found no long-term data for serious adverse events.Scheduled PDE5I versus scheduled intraurethral prostaglandin E1At short-term follow-up, daily PDE5I may result in little or no effect on self-reported potency (RR 1.10, 95% CI 0.79, to 1.52; very low quality evidence), which corresponds to 46 more men per 1000 (95% CI 97 fewer to 241 more). Daily PDE5I may result in a small improvement of erectile function (RR 1.64, 95% CI 0.84 to 3.20; very low quality evidence), which corresponds to 92 more men per 1000 (95% CI 23 fewer to 318 more) but we are very uncertain of both these findings. We found no long-term (longer than 12 months) data for any of the three primary outcomes.We found no evidence for any other comparisons and were unable to perform any of the preplanned subgroup analyses based on nerve-sparing approach, age or baseline erectile function. AUTHORS' CONCLUSIONS Based on mostly very-low and some low-quality evidence, penile rehabilitation strategies consisting of scheduled PDE5I use following radical prostatectomy may not promote self-reported potency and erectile function any more than on demand use.

Abstract
BACKGROUND Prostaglandin E1 (PGE1) is widely used as a pretreatment for myocardial reperfusion injury in animal experiments. However, the cardioprotective effects of PGE1 in patients have not been established. We performed a meta-analysis to investigate whether PGE1 is cardioprotective, based on the reduction of correlative reperfusion injury events (CRIE), major adverse cardiac events (MACE), and biomarker release in patients with ischemia reperfusion injury. METHODS The Medline, EMBASE, and Cochrane databases were searched for randomized clinical trials confirming the effects of PGE1. Two investigators independently selected suitable trials, assessed trial quality, and extracted data. RESULTS Six studies in patients undergoing percutaneous coronary intervention (4 studies) and cardiac surgery (2 studies), comprising a total of 445 patients, were included in this review. The results showed that PGE1 reduced the incidence of CRIE (relative ratio 0.4 [95% confidence interval 0.43, 0.95]), the incidence of MACE (0.35 [0.17, 0.70]), and the level of troponin T (standardized mean difference 20.28 [20.47, 20.09]), creatine kinase-MB (-1.74 [-3.21, - 0.27]), interleukin-6 (-1.37 [-2.69, - 0.04]), and interleukin-8 (-2.05 [-2.75, - 1.34]). CONCLUSION PGE1 may have beneficial effects on myocardial reperfusion injury in the clinic.

Abstract
OBJECTIVE To analyse the predictive utility of penile colour Doppler ultrasonography after the injection of vasoactive agents for recovering erectile function after radical prostatectomy. MATERIAL AND METHODS A retrospective study was conducted on patients with erectile dysfunction after radical prostatectomy who were treated with intracavernous injections of prostaglandins E1 between January 1, 2006 and December 31, 2012. The study included patients with no history of erectile dysfunction prior to the surgery and who did not respond to medical treatment. Colour Doppler was performed on all patients after the intracavernous injection. A peak systolic velocity ≥30cm/sec and an end diastolic velocity ≤5cm/sec were considered normal haemodynamic values. We assessed the result of the treatment during the follow-up using the International Index of Erectile Function-5. RESULTS We included 197 patients. The mean age was 60.8 (±6.3). The pathological diagnosis for all patients was adenocarcinoma, 74.1% of which were confined to the organ (T1-T2/Nx-N0). Treatment with injections after the surgery was started after a mean duration of 6.8 months (+3.5). The Doppler ultrasonography results were normal for 53 patients (26.9%). During the follow-up, 113 patients (57.4%) maintained functional erections; 55 of these patients (28%) did not require injections. Normal Doppler ultrasonography results were associated with a favourable response to treatment (p<.01). CONCLUSIONS The prostaglandin E1 test will help provide a diagnosis in erectile dysfunction for patients who have undergone prostatectomies. The test helps provide information on the vascular condition of the penis and useful prognostic information for the follow-up of these patients.

Abstract
D-transposition of the great arteries (D-TGA) is the most commonly diagnosed cyanotic congenital heart disease presenting in the neonatal period. The survival after an arterial switch operation, with freedom from adverse cardiovascular events, has been reported to be as high as 93% at 25 years. However, despite excellent surgical outcomes, there continues to be significant preoperative morbidity and potential mortality due to compromise in the delivery room from foramen ovale closure requiring urgent balloon atrial septostomy for stabilization in the first minutes of life. The prenatal diagnosis of D-TGA using fetal echocardiography has aided in the perinatal management and delivery planning of these infants, lowering preoperative morbidity and mortality and preventing delivery room compromise. Fetuses with D-TGA have more highly oxygenated blood supplying the pulmonary arteries and ductus arteriosus which likely results in ductal constriction and increased pulmonary blood flow. This may be the cause of foramen ovale restriction or closure in-utero, which then increases the risk for postnatal compromise at delivery. Theories regarding the cause of the abnormal pulmonary vasculature that may be seen in D-TGA, including aorto-pulmonary collateral formation, have been proposed but to our knowledge, observation of the ultrasound findings throughout mid and late gestation describing the progression of the abnormal fetal physiology have not been previously described. We present a case of D-TGA in which serial assessment using fetal echocardiography enabled observation of the in-utero progression of disease, predicting postnatal compromise and facilitating the planning of life-saving specialized delivery room care and intervention.

Abstract
OBJECTIVE To observe the clinical efficacy of different doses of alprostadil (lipo-prostaglandin E1, lipo-PGE1) in the treatment of painful diabetic peripheral neuropathy (DPN). METHODS Sixty patients with painful DPN were equally and randomly assigned into three groups. Two groups received different doses of lipo-PGE1 by intravenous drip injection (A group: low-dose lipo-PGE1; B group: high-dose lipo-PGE1) following intravenous bolus injection of mecobalamin (MeCbl, 0.5mg once daily (QD)); the third group received MeCbl alone (C group). All patients received optimized treatment to lower blood glucose, blood pressure, and blood lipids to target levels. The efficacy of lipo-PGE1 in the three groups of patients was observed after 3weeks of treatment. RESULTS The overall response rate was 90% in the B group, significantly higher than that in the A and C groups (80% and 55%, respectively; P<0.05). During the observation period, there was no incidence of serious adverse reactions (e.g., acute heart failure, sudden drop in blood pressure, or malignant arrhythmias) in any of the three groups. CONCLUSIONS High-dose lipo-PGE1 has better efficacy than low-dose lipo-PGE1 or MeCbl alone in the treatment of painful DPN.

Abstract
The incidence rate of erectile dysfunction (ED) is reportedly as high as 30-90% after radical prostatectomy for prostate cancer, which seriously affects the patients' quality of life. Penile rehabilitation is defined as the use of any drug or device at or after radical prostatectomy to maximize erectile function recovery. A variety of treatment options are available for post-prostatectomy ED patients, including oral phosphodiesterase 5 inhibitors (PDE5I) , intracorporal injections, vacuum erection device, and penile prosthesis. This article presents an overview of the currently used methods for the drug treatment and penile rehabilitation of the ED patients after radical prostatectomy. It seems proper to recommend daily use of a vacuum erection device plus oral PDE5I in the early postoperative period. For those who fail to respond to this therapy, intraurethral alprostadil, intracorporal injections, or a penile prosthesis could be considered.

Abstract
Alprostadil, a prostaglandin, has been marketed for many years as a urethral stick and an intracavernous injection for the treatment of erectile dysfunction.(1) It is now available in the form of a cream (Vitaros-Takeda). Adverts for the product declare: "Sex with no pills, pellets or needles. Spot on." In this article, we consider the evidence for alprostadil cream, and its place in the management of erectile dysfunction.

Abstract
We herein report a case regarding a 90-year-old woman with a history of recurrent episodes of urinary tract infections presenting with fever. Urinalysis revealed bacteria and white blood cells. Computed tomography showed dilated and fecally loaded rectum and colon with signs of obstructive uropathy. The patient was treated for urinary tract infection and constipation. Her bowel habits were controlled with lubiprostone, and she was discharged in good medical condition. This case highlights the importance of considering fecal impaction as a cause of urinary tract obstruction or infection.

Abstract
BACKGROUND Peripheral arterial disease is a major health problem, and in about 1% to 2% of patients the disease progresses to critical limb ischaemia (CLI). In a substantial number of patients with CLI, no effective treatment option other than amputation is available and around a quarter of these patients will require a major amputation during the following year. This is an update of the review first published in 2011. OBJECTIVES To determine the effectiveness and safety of local intramuscular transplantation of autologous adult bone marrow mononuclear cells (BMMNCs) as a treatment for critical limb ischaemia (CLI). SEARCH METHODS For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched February 2014) and the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 1). SELECTION CRITERIA We included all randomised controlled trials of CLI in which participants were randomly allocated to intramuscular administration of autologous adult BMMNCs or control (either no intervention or conventional conservative therapy). We excluded studies on patients with intermittent claudication. DATA COLLECTION AND ANALYSIS Two authors independently selected trials, assessed trials for eligibility and methodological quality, and extracted data. Disagreements were resolved by consensus or by the third author. MAIN RESULTS Only two small studies, with a combined total of 57 participants, met our inclusion criteria and were finally included. They were classified as having a moderate risk of bias with unclear issues regarding their methods, and according to the GRADE approach, the overall quality of the evidence would be considered as moderate. In one study the effects of intramuscular injections of BMMNCs in the ischaemic lower limbs of patients with CLI were compared with control (standard conservative treatment). No deaths were reported and no significant difference was observed between the two groups for either pain (P = 0.37) or the ankle brachial index (ABI) parameter. However, the treatment group showed a significantly smaller proportion of participants undergoing amputation compared with the control group (P = 0.026).In the other study, following subcutaneous injections of granulocyte colony-stimulating factor (G-CSF) for five days, peripheral blood derived mononuclear cells were collected and then transplanted by intramuscular injections into ischaemic lower limbs. The effects were compared with daily intravenous prostaglandin E1 injections (control group). No deaths were reported. Pain reduction was greater in the treatment group than in the control group (P < 0.001) as was increase in ABI (mean increase 0.13 versus 0.02, P < 0.01). The treatment group experienced a statistically significant increase in pain-free walking distance (PFWD) compared with the control group (mean increase 306.4 m versus 78.6 m, P = 0.007). A smaller proportion of participants underwent amputation in the treatment group compared with the control group (0% versus 36%, P = 0.007). AUTHORS' CONCLUSIONS The data from the published trials suggest that there is insufficient evidence to support this treatment. These results were based on only two trials which had a very small number of participants. Therefore evidence from larger randomised controlled trials is needed in order to provide adequate statistical power to assess the role of intramuscular mononuclear cell implantation in patients with CLI.

Abstract
OBJECTIVE To evaluate if the 72 hours interval between mifepristone and gemeprost has a similar efficacy compared to the 48 hours interval for second trimester termination of pregnancy STUDY DESIGN Two-hundred and fifteen consecutive pregnant women, admitted to our hospital, for second trimester TOP, were included in this retrospective analysis. Standard protocol was followed for all patients. On the first day of the procedure oral mifepristone 200 mg was administered. After 72 (group A, n = 78) or 48 hours (group B, n = 113) women were admitted for administration of gemeprost 1 mg pessary as per protocol. The induction to abortion time was defined as the interval between the insertion of the first gemeprost pessary and the expulsion of the fetus. RESULTS There are no significant differences in the number of pessaries in the two groups. The induction to abortion interval was longer in group A than in group B. Twenty-one women required surgical evacuation of the uterus for retained placenta or incomplete abortion without difference between groups. CONCLUSION A 48-hours interval between mifepristone and gemeprost leads to better results than a 72-hours interval, with a shorter abortion length and represents the elective method for second trimester TOP.

Abstract
OBJECTIVES Fetuses with pulmonary outflow tract obstruction (POTO) have altered blood flow to the pulmonary vasculature. We sought to determine whether pulmonary vascular impedance, as assessed by the pulsatility index (PI), is different in fetuses with POTO compared with normal controls. METHODS Branch pulmonary artery PI was evaluated in age-matched normal control fetuses (n=22) and 20 POTO fetuses (pulmonary stenosis n=15, pulmonary atresia n=5). Pulsed-wave Doppler was performed in the proximal (PA1), mid (PA2) and distal (PA3) branch pulmonary artery. The direction of flow in the ductus arteriosus was noted. The study and control groups were compared with Student's t-test and ANOVA. A linear mixed model evaluated the relationship between PI and ductus arteriosus flow patterns. RESULTS There was no difference in PI between control, pulmonary stenosis and pulmonary atresia subjects at PA1 and PA2; however, there was a significant difference at PA3. Subjects with pulmonary atresia had a lower PI at PA3 than did controls (P=0.003) and pulmonary stenosis subjects (P=0.003). Subjects with retrograde flow in the ductus arteriosus had lower PIs in PA2 and PA3 than did those with antegrade flow (P=0.01 and 0.005, respectively). The PI in PA3 was lower in fetuses that required prostaglandin postnatally than in those that did not (P=0.008). CONCLUSIONS Fetuses with pulmonary atresia or severe pulmonary stenosis with retrograde flow in the ductus arteriosus have decreased PI in the distal pulmonary vasculature. Our findings indicate the capacity of the fetal pulmonary vasculature to vasodilate in response to anatomical obstruction of flow.

Abstract
The only prostaglandin analogue licensed in Italy for induction of labour in spontaneous and therapeutic abortion is gemeprost. The authors report a case of spontaneous uterine rupture of a scarred uterus, for previous caesarean sections, in a woman at 20 weeks of gestation with a diagnosis of spontaneous abortion. She received a pessary of gemeprost every three hours. After the fifth pessary, she complained of severe pain. At the ultrasound examination, uterine cavity appeared empty and the dead fetus was dislocated in the abdomen. Emergency laparotomy was performed and uterine tear was repaired. To induce labour for fetal demise or therapeutic abortion in second trimester in women with scarred uterus, the authors decided to lengthen the time between administrations of pessary from four to five hours depending on patient's symptoms. However the appropriate drug regimen has still to be found and more data are necessary.

Abstract
PURPOSE To present the use of intravenous prostaglandin E1 (PGE1), a powerful vasodilator of the microcirculation, in the treatment of an ischemic diabetic eye. METHODS A 27-year-old diabetic man with ischemic diabetic retinopathy and glaucoma had a decreased visual acuity of no light perception in his right eye and hand motions in his left eye. He was started on intravenous PGE1 and has been treated for over 4.5 years. RESULTS The visual acuity in his right eye remained unchanged and in his left eye improved gradually to 1.5/30. He has been stable for 4.5 years. CONCLUSION Intravenous PGE1 may be useful in ischemic diabetic eyes to improve the ocular blood flow and visual acuity. It is safe and tolerated well.

Abstract
Prostaglandin E1 (PGE1) is the drug of choice for providing ductal patency in cyanotic congenital heart disease (CCHD) for a short period of time until essential surgical management. Occasionally, prolonged use of PGE1 is required when the surgical procedure is delayed due to certain clinical conditions. Prolonged use of PGE1 may lead to bone and tissue changes such as pretibial and soft tissue swelling of the extremities and reversible cortical proliferation of the bones. Venous stasis as an additional risk factor can result in generalized periosteal reaction that initially can cause the separation of the periosteum from the cortex. We report an infant with CCHD who developed severe tissue swelling and generalized periosteal reaction due to coexistence of prolonged use of PGE1 and venous stasis. To the best of our knowledge, this is the first case report with both of these risk factors.

Abstract
PURPOSE To evaluate the protective effects of alprostadil on contrast-induced nephropathy (CIN) in elderly patients. METHODS We randomized 370 patients into the control or alprostadil group. The patients in the control group were injected with 100 ml sterile saline and the patients in the alprostadil group with alprostadil (0.4 μg/kg/day) in 100 ml sterile saline before and after iohexol-enhanced (100 ml) computed tomography (CT). Serum creatinine (Scr), blood urea nitrogen (BUN), cystatin C (CysC), and creatinine clearance (Ccr) were analyzed or calculated. ΔScr and ΔCysC were determined by the changes between baseline and highest Scr and CysC levels. The standard for CIN was a postdose Scr increase >44.2 μmol/l or >25 % over baseline. RESULTS In the control group, peak Scr (P < 0.05) and ΔScr (P < 0.01) were higher than those in the alprostadil group. The postdose CysC at 24 h (P < 0.05), 48 h (P < 0.05), and 72 h (P < 0.05), peak CysC (P < 0.01), and ΔCysC (P < 0.05) in the control group were higher than those in the alprostadil group. The incidence of CIN in the control group was 22.2 %, which was higher than in the alprostadil group (9.1 %, P < 0.01). Subgroup analyses in patients with advanced age (≥ 80 years), concomitant hypertension or diabetes, and abnormal baseline renal function (Ccr ≤ 60 ml/min) showed that the alprostadil group had lower ΔScr and ΔCysC than the control group after contrast-enhanced CT examination in all four subgroups (P < 0.05 or P < 0.01). CONCLUSIONS In this cohort of older patients undergoing contrast CT, the use of alprostadil reduced the incidence of CIN.

Abstract
OBJECTIVE The study was aimed at assessing efficacy and safety of administering the generic alprostadil VAP in patients presenting with lower limb critical ischaemia. MATERIAL AND METHODS We carried out a prospective study including a total of 30 patients with lower limb critical ischaemia. The patients' mean age was 67.7±7.8 years, with men predominating - 60%. Trophic ulcers were observed in 40% of patients. The proximal level of the lesion was localized in the arteries below the inguinal ligament in 19 (63.3%) patients, in the aortofemoral segment - in 9 (30%) patients, and in the popliteal-crural-plantar segment - in 2 (6.6%) subjects. The average ankle-brachial index amounted to 0.49±0.4. The studied agent was used at a dose of 40 mcg once a day in patients with stage III ischaemia and a dose of 40 mcg twice daily in patients with stage IV ischaemia. The drug was administered for 14 days followed by a 14-day follow-up period. RESULTS The pain syndrome score over the 14 days of treatment decreased twofold from 6.1±2.5 to 3.5±2.6 and within the subsequent 14 days it did not increase - 2.4±3.1 (p< 0.05). The number of patients in whom the pain syndrome decreased by 50% amounted to 19 (63.3%). The consumption of analgesic agents decreased from 60% (at the beginning of treatment) to 12 (40%) (14 days after treatment) and to 8 (26.6%) (at the end of the follow-up period). In patients with trophic ulcers, the average size of the ulcers during treatment decreased from 3.3±3.7 cm to 2.8±3.8 after 14 days, and at the end of the follow-up period the size of the ulcers amounted to 2.1±2.8 cm (p >0.05). The number of patients responding to treatment amounted to 22 (77.3%). The ABI during treatment did not change, being 0.49 ± 0.4 at the beginning of treatment, 0.53±0.4 after 14 days of treatment, and 0.47±0.3 at the end of the follow-up period. There were no amputations either during treatment or within the follow-up period. Only one lethal outcome occurred which was related to acute coronary insufficiency. The "response to treatment" was significantly influenced only by the level of the proximal lesion and age (p<0.05). CONCLUSION VAP 20® demonstrated good efficacy and tolerability comparable to those of the original preparations.

Abstract
OBJECTIVE To investigate the effect of prostaglandins E1 combined with Xuebijing injection on the expression of transforming growth factor-β₁ (TGF-β₁) and tumor necrosis factor-α (TNF-α) in rats with acute pulmonary interstitial fibrosis. METHODS A rat model of pulmonary interstitial fibrosis was established by intratracheal injection of bleomycin (1 ml/kg). One hundred and eight Wistar rats were randomly divided into six groups with 18 in each group, which were normal control group, model group, hormone (methylprednisolone) treatment group, Xuebijing treatment group, prostaglandin E1 treatment group and combination treatment group (prostaglandin E1 and Xuebijing injection). Except for those in the normal control group, the rats in each group were sacrificed on the 7th, 14th and 28th day after treatment. The TGF-β₁ expression in lung tissue was measured by immunohistochemical staining. The TNF-α concentration in bronchoalveolar lavage fluid (BALF) of rat model was determined by enzyme-linked immunosorbent assay. RESULTS The combination treatment group showed significantly more macrophages with TGF-β₁ expression in lung tissue at each time point, as compared with the model group, Xuebijing treatment group, methylprednisolone treatment group and prostaglandin E1 treatment group (P < 0.05). On the 7th day, the TNF-α concentration in BALF in the combination treatment group was significantly lower than those in the model group, methylprednisolone treatment group and prostaglandin E1 treatment group (P < 0.05); on the 14th day, the TNF-α concentration in BALF in the combination treatment group was significantly lower than that in the model group (P < 0.05); on the 28th day, the levels of TNF-α in the prostaglandin E1 treatment group and combination treatment group were significantly lower than that in the model group (P < 0.05). CONCLUSION Prostaglandin E1 combined with Xuebijing injection may significantly inhibit TGF-β₁ expression in the lung tissue of rats with acute pulmonary interstitial fibrosis, which reduces alveolar inflammatory response.

Abstract
PURPOSE Vascular disorders and viral infections are considered the main causes of sudden hearing loss (SHL), although its pathogenesis remain unclear. Treatments include carbogen inhalation and lipo-prostaglandin E1 (lipo-PGE1), both of which have circulation-enhancing effects. We investigated the effectiveness of carbogen inhalation and lipo-PGE1 in SHL. MATERIALS AND METHODS This retrospective review included 202 patients with idiopathic SHL who visited our clinic within 14 days of symptom onset between January 2006 and June 2010. All patients received oral prednisolone for 10 days. Of the 202 patients, 44 received no additional treatment, 106 received additional carbogen inhalation, and 52 received additional lipo-PGE1. Hearing improvement was measured using Siegel's criteria. RESULTS Overall recovery rates were 67.9% in the carbogen group, 53.8% in the lipo-PGE1 group, and 52.3% in the steroid-only control group (p=0.097). Limited to type 1 and type 2 categories of Sigels's criteria, the carbogen group had a significantly higher recovery rate (53.8%) than the lipo-PGE1 group (26.9%) and the steroid-only control group (38.6%) (p=0.005). CONCLUSION Carbogen inhalation added to steroid was a more effective treatment than lipo-PGE1 added to steroid or steroid alone in patients with SHL.

Abstract
AIM Intermittent claudication (IC) in peripheral vascular disease is characterized by lower limb pain appearing on effort. Treatment with PGE1 has been successfully used to manage IC patients. This registry has evaluated safety and costs of PGE1 in the management of IC. METHODS In this study a long-term treatment protocol (LTP), a short-term protocol (STP) and an outpatient (OP), "on-demand" treatment have been compared. A treadmill effort test has been used to evaluate walking distance. The follow up for these three protocols was 40 weeks. PGE1 treatment was associated to a risk reduction plan and to an exercise program. RESULTS The final analysis has included 252 LTP patients, 223 STP patients and 284 OP patients (total 659 valid cases). A group of 171 comparable patients not treated with PGE1 was used for a parallel comparison. Cardiovascular mortality and morbidity has been evaluated in 731 PGE1 patients completing 24 months of follow up. All protocols have been well tolerated. No side effects were observed. The lower cost has been observed for OP patients. In the long term, mortality and morbidity were lower in patients treated with PGE1 in comparison with patients not treated with PGE1. CONCLUSION Considering costs and results (increase in walking distance) and improvement in Karnofsky scale the STP plan appears to be better than LTP for IC patients. The OP, "on-demand" treatment offers further improvements. This last treatment plan is simpler; the plan allows better timing for exercise. The treatment can be used even in non-specialized centers.

Abstract
INTRODUCTION To evaluate erectile function among men who had undergone laparoscopic radical prostatectomy and received postoperative medical therapy for erectile dysfunction. MATERIALS AND METHODS We performed a prospective study in men who underwent laparoscopic radical prostatectomy between September 2003 and November 2005 at our center and who received penile rehabilitation after surgery. All patients had antegrade interfascial dissection. They received 10 mg tadalafil on the fifth postoperative day and continued to receive it every other day, regardless of erectile function. Intracavernous injection of alprostadil was initiated at 3 or 6 months depending on response to treatment with tadalafil. Follow up evaluations were done at 3, 6, 12, 18 and 24 months. Oncologic and functional outcomes and compliance were assessed. Patients filled in International Index of Erectile Function-5 (IIEF-5) questionnaires. RESULTS Of 1078 men who underwent laparoscopic radical prostatectomy during this time, 586 patients met inclusion criteria, complied with the study medication, and had complete data for 24 months. The patients had a median preoperative baseline IIEF-5 score of 22. A total of 150 patients (26%) underwent unilateral nerve-sparing surgery, while 436 patients (74%) had bilateral nerve-sparing surgery. At 24 months, 35% of patients who underwent unilateral nerve-sparing surgery and 68% of patients who underwent bilateral nerve-sparing surgery reported having sufficient erectile function for intercourse without using intracavernous injection of alprostadil. At 24 months after surgery, the median IIEF-5 score was 13 (1-25) for the whole cohort, 5 (1-25) for patients who had undergone unilateral nerve-sparing surgery, and 15 (1-25) for patients who had undergone bilateral nerve-sparing surgery. CONCLUSIONS The findings suggest that adequate patient selection and postoperative medical intervention allows the preservation or recovery of erectile function after laparoscopic radical prostatectomy. Inaccurate selection of patients and postoperative assessment might explain inferior erectile function results following this surgery.

Abstract
PURPOSE Prostaglandin E1 (PGE1) has been used to improve hepatic blood flow and to reduce ischemia reperfusion injuries of allografts in liver transplantation. However, PGE1 undergoes extensive metabolic clearance in the pulmonary and splanchnic circulation during intravenous administration. We analyzed the effect of intraportally administered PGE1. METHODS Sixty living-donor liver transplant recipients received continuous infusions of PGE1 for 10 days immediately after the reperfusion of the allografts. Of them, 40 recipients received PGE1 intravenously (IV group) via the internal jugular vein, and 20 recipients received PGE1 intraportally (IP group) through a catheter in the inferior mesenteric vein. Data were collected for 3 weeks postoperatively. RESULTS The IP group exhibited lower initial aspartate aminotransferase and alanine aminotransferase levels compared with the IV group. However, no apparent differences were recognized in the serum albumin, total bilirubin, alkaline phosphatase, r-glutamyl transpeptidase, or prothrombin time levels between the 2 groups. Chylorous ascites were observed more frequently in the IP group. There was no difference in portal venous flow measured by Doppler sonogram between the 2 groups during the first postoperative week. CONCLUSION This study demonstrated that intraportal administration of PGE1 had a better cytoprotective effect against hepatocellular damage than intravenous administration, although it did not have additional benefits for perihepatic hemodynamics.

Abstract
Postoperative decline of renal function remains a common and unpredictable complication after abdominal aortic aneurysm (AAA) reconstruction. The oxidative stress that occurs during perioperative ischemia/reperfusion injury (I/R) may contribute to the development of this complication. In this study, the influence of intraoperative prostaglandin E (alprostadil) administration on erythrocyte and platelet antioxidants as well as postoperative kidney function modulation were verified. AAA patients were randomly divided into control and study/alprostadil groups. Blood samples were collected directly before aortic clamping and 5 min after aortic declamping. Superoxide dismutase, catalase, glutathione, glutathione peroxidase (GPx), and glutathione transferase (GST) were measured using spectrophotometry. During I/R, the activity of catalase (57.14+/-30.65 vs 128.35+/-91.94 U/mg protein; P < 0.009), GPx (0.21+/-0.18 vs 0.35+/-0.21 mU/g protein; P = 0.028), and GST (217.49+/-101.39 vs 310.66+/-88.86 mU/g protein; P = 0.0006) significantly increased in the control group. GST activity before the aortic clamping was significantly lower in the study/alprostadil group (2.84+/-2.28 vs 3.48+/-2.30 U/g Hb; P = 0.05). The activity of the selected antioxidants proved to be of a diagnostic value for predicting postoperative decline in renal function. In conclusion, during I/R after AAA reconstruction, activation of various erythrocyte and platelet antioxidants occurs. Perioperative administration of alprostadil is associated with disruption of this activation.

Abstract
The termination of pregnancy trial (Newcastle upon Tyne, UK), is the only randomised trial on termination of pregnancy methods incorporating a qualitative element that aimed to understand the experiences of women participating in the trial. Based on the results of this qualitative work, this article aims to provide insights into two strands of understanding; firstly, women's experience of participating in research about abortion and secondly, their experience of participating in a randomised preference trial. Semi-structured interviews were conducted of up to 90 minutes with 30 participants recruited at a single hospital site. A total of 20 women from the preference arm and 10 from the random arm were interviewed. The analysis and discussion of our findings use reflexive modernisation as a framework for understanding and interpreting some of the actions of social agents, that is, the participants and trial recruiters in the course of a clinical trial as an expert system. We found that the factors that shape women's experiences and decisions include trust in the expert system and reflexivity and agency on the part of both participants and trial recruiters.

Abstract
The efficacy of combined high-dose steroid and PGE1 treatment initiated immediately after the onset of sudden deafness was analyzed with the outcome of 174 patients begun on treatment within 7 days of the onset of sudden deafness. Four potential prognostic factors (days from onset to treatment, age, initial hearing level, presence of vertigo) and hearing outcome were examined with a multiple logistic regression analysis. Days from onset to treatment and age significantly correlated with hearing improvement. The efficacy of the treatment of patients begun on treatment within 3 days of the onset was significantly better than that of patients on treatment 4-7 days after the onset (p < 0.001). In the examination of patients younger than 50 years, the efficacy of the treatment of patients begun on treatment within 3 days of the onset didn't differ significantly from that of patients on treatment 4-7 days after the onset. On the other hand, in the examination of patients aged 50 years and older, the efficacy of the treatment of patients begun on treatment within 3 days of the onset was significantly better than that of patients on treatment 4-7 days after the onset (p < 0.001). These results suggest that significant efficacy may be expected from the combined high-dose steroid + PGE1 treatment, if its use is started within 7 days of the onset of sudden deafness, and started within 3 days of the onset of sudden deafness in patients 50 years old and older.

OBJECTIVES Chemokines favour leukocyte homing and participate actively in inflammation and accumulation of extracellular matrix. The aim of our work is to assess in patients with systemic sclerosis (SSc) the serum levels of CC chemokines: CCL2 monocyte chemotactic protein-1 (MCP-1/CCL2), CCL5 'regulated upon activation, normal T expressed and secreted' (RANTES/CCL5) and CCL3 'macrophage inflammatory protein 1 α' (MIP1α/CCL3), their associations with clinical characteristics and modulation by infusions of the prostaglandin E1 (PGE1) analogue, alprostadil alpha-cyclodextrin. METHODS Serum levels of MCP1/CCL2, RANTES/CCL5 and MIP1α/CCL3 were studied by ELISA in 40 patients with SSc (34 lSSc, 6 dSSc) before and after 3 consecutive daily PGE1 infusions (60 μg) and compared to 30 healthy controls. We recorded clinical (age, duration of disease, ulcers, teleangectasias, calcinosis, skin score [mRSS], capillaroscopy pattern, heart and lung involvement) and immunological characteristics (ANA/ACA/Scl70) of patients. RESULTS MCP1/CCL2, RANTES/CCL5 and MIP1α/CCL3 levels were significantly higher in SSc patients than in controls and significantly decreased after PGE1 treatment. MCP-1 levels, higher in dSSc and Scl 70 positive patients, correlated with mRSS. CONCLUSIONS The high levels of circulating chemokines might support a role of MCP1/CCL2, RANTES/CCL5 and MIP1α/CCL3 in SSc pathogenesis and the correlation of MCP-1 with the extent of skin fibrosis might imply its involvement in the development of fibrosis in SSc. PGE1 down-regulates serum MCP1/CCL2 and RANTES/CCL5 levels, suggesting its possible additional effect on inflammation and cell trafficking in SSc.

Abstract
BACKGROUND scoliosis correction surgery is common in children, and adolescents. Deliberate hypotension is indicated in scoliosis correction procedures, because bloodless field is needed for exposure of the nerve roots, and to decrease the need for blood transfusion. Protection of the kidneys during deliberate hypotension is essential. The ideal hypotensive drug maintains the renal function and the urine output during the period of hypotension. Aim of this study is to compare Prostaglandin E1, and Esmolol hypotensive effects, bleeding score, and their effects on the serum creatnine, and urine output. PATIENTS AND METHODS Twenty patients under went hypotensive anesthesia during scoliosis correction procedure, were enrolled in this clinical trial. In group 1 (n = 10) (Esmolol infusion), group 2 (n = 10) (prostaglandin E1 infusion), Parameters were measured: Mean arterial blood pressure, Heart rate, (preoperative, just after induction, 15 minutes, 30 minutes, 60 minutes after starting the infusions, and 15 minutes after discontinuation of infusions). The bleeding score was assessed at (15 minutes, 30 minutes, 60 minutes after starting the infusions). RESULTS heart rate was significantly higher in prostaglandin E1 group than Esmolol group at 15, 30, 45, and 60 minutes. There was significant difference in the bleeding score only after 30 minutes, The target mean blood pressure (50 mmHg) was achieved at 30 minutes in group 2 (prostaglandin E1), while it was achieved at 60 minutes in group 1 (Esmolol group). There were significant differences in Mean blood pressure between both groups at 15, 30, 45, 60 minutes after starting the infusions. Creatnine level was significantly lower in prostaglandin E1 group, while the introperative urine output was significantly higher in prostaglandin E1 group. CONCLUSIONS Prostaglandin E1 hypotensive effects started earlier than Esmolol and its bleeding score is better than esmolol especially at thirty minutes after initiation of the infusion. Prostaglandin E1 can maintain renal function and urine output more than Esmolol. This study recommended using Prostaglandin E1 to induce hypotensive anesthesia in scoliosis correction

Abstract
A 74-year-old man underwent an operation for an extremely large mediastinal tumor. Despite the lack of respiratory difficulty or distention of the jugular veins, preoperative computed tomography showed suppression of the left atrium by the huge tumor. We suspected pulmonary hypertension and monitored continuously with a pulmonary catheter. The Pp/Ps ratio decreased gradually from 0.8 to 0.7 by continuous administration of alprostadil or olprinone. After tumor resection, the Pp/Ps ratio was reduced and maintained at 0.2 even after alprostadil and olprinone administration was discontinued. The tumor was considered to have caused the severe pulmonary hypertension, as anticipated from the preoperative CT.

Abstract
The aim of this study was to investigate the expression of prostaglandin EP1 receptor within the ventrolateral periaqueductal grey (VL PAG). The role of VL PAG EP1 receptor in controlling thermonociception and rostral ventromedial medulla (RVM) activity in healthy and neuropathic rats was also examined. EP1 receptor was indeed found to be expressed within the VL PAG and co-localized with vesicular GABA transporter. Intra-VL PAG microinjection of ONO-DI-004, a selective EP1 receptor agonist, dose-dependently reduced tail flick latency as well as respectively increasing and decreasing the spontaneous activity of ON and OFF cells. Furthermore, it increased the ON cell burst and OFF cell pause. Intra-VL PAG prostaglandin E2 (PGE2) behaved similarly to ONO-DI-004. The effects of ONO-DI-004 and PGE2 were antagonized by intra-VL PAG L335677, a selective EP1 receptor antagonist. L335677 dose-dependently increased the tail flick latency and ongoing activity of the OFF cells, while reducing the ongoing ON cell activity. It also decreased the ON cell burst and OFF cell pause. In neuropathic rats using spare nerve injury (SNI) of the sciatic nerve model, EP1 receptor expression decreased in the VL PAG. However, ONO-DI-004 and L335677 were able to alter pain responses and ON and OFF cell activity, as they did in healthy animals. Collectively, these data show that within the VL PAG, EP1 receptor has a facilitatory effect on the nociceptive response and consistently affects RVM neuron activity. Thus, the blockade of EP1 receptor in the VL PAG leads to antinociception in neuropathic pain conditions, despite its down-regulation. The expression of EP1 receptor on GABAergic neurons is consistent with an EP1 receptor blockade-induced disinhibition of the antinociceptive descending pathway at VL PAG level.

Abstract
BACKGROUND AND PURPOSE Radiofrequency (RF) is an efficient, inexpensive, safe, and friendly option for the management of small renal tumors. The objective was to evaluate the ideal temperature for renal cell destruction in dogs by RF and to verify whether the injection of vasoactive drugs, such as prostaglandin E1 and adrenaline, can help to improve the results, compared with "dry" RF ablation. MATERIALS AND METHODS The study was divided into three phases: Initially, 16 dogs of comparable weight underwent RF ablation of the renal parenchyma at temperatures of 80°C, 90°C, and 100°C. After that, seven other dogs received adrenaline (vasoconstrictor) and seven received prostaglandin E1 (vasodilator). Finally, the results from 14 animals were compared with those of the 16 (dry RF) dogs at the optimum temperature found. After 14 days, the animals underwent nephrectomy to evaluate the size of the lesions (width and depth), histology examination, and were then sacrificed. RESULTS There were no clinical or surgical complications in any of the dogs, and none died before the 14th day after the procedure. The optimum temperature was found to be 90°C. Prostaglandin E1 resulted in significantly larger lesions (in depth and width) than adrenaline, with lower impedance. Prostaglandin did not increase the lesions compared with dry RF. All the kidneys presented total coagulation necrosis, with no viable cells in the histologic analysis of the treated tissue. CONCLUSION In the ablation of renal cells by RF, prostaglandin produced larger lesions (in depth and width) than the same procedure using adrenaline, and its performance was similar to that of RF without injection of drugs.

Abstract
Ischemia of the optic nerve, the retina and the choroid are common problems in ophthalmology. This paper presents the different types of ischemia and their treatment with prostaglandin E1 (PGE1), a powerful vasodilator of the microcirculation. This is a review article of various previously published case reports and studies presenting patients with different types of ocular and optic nerve ischemia. Their treatment with intravenous (IV) PGE1 is described. Treatment for acute and chronic problems is presented. The visual acuity and/or the visual fields improved in almost all the treated patients. When measured, the blood flow velocities also improved. No complications due to the use of PGE1 were seen. Treatment with IV PGE1 should be considered in cases of ocular and optic nerve ischemia to immediately restore blood flow to these structures and improve the visual acuity. Intravenous prostaglandin E1 is an effective treatment for ocular and optic nerve ischemia leading to immediate visual improvement.

Abstract
The optimal prescription of transdermal preparations of prostaglandin E1 (PGE1) for treatment of peripheral vascular diseases has been investigated. The chemical stability of PGE1 in fatty alcohol/propylene glycol (FAPG) ointment was markedly improved by carboxymethyl-ethyl-β-cyclodextrin (CME-β-CyD). Application of a PGE1 ointment containing the penetration enhancer, 1-dodecylazacycloheptane-2-one (Azone) or 1-[2-(decylthio)ethyl]azacyclopentane-2-one (HPE-101), onto the skin of hairless mice showed the increase of blood flow in the skin due to the vasodilating action of PGE1. In particular, the ointment containing a PGE1-CME-β-CyD complex supplemented with HPE-101 showed the most prominent increase of the blood flow. Compared with other ointments, this ointment was found to show significantly greater transfer of HPE-101 into in-vitro preparations of the skin of hairless mice. Transfer of PGE1 into the skin was thought to be facilitated by this increased transfer of HPE-101. These results suggest that a combination of CME-β-CyD and HPE-101 is useful for designing PGE1 ointments for topical application with good chemical stability and percutaneous permeability.

Abstract
OBJECTIVE Recent investigation has demonstrated that prostaglandin E(1) (PGE(1)) therapy increased capillary density in explanted hearts. Dynamic (13)N-ammonia positron emission tomography (PET) is reliable for non-invasive measurement of myocardial blood flow and myocardial perfusion reserve (MPR). The aim of this study was to investigate the effects of PGE(1) therapy during 4 weeks on reduction of myocardial perfusion abnormalities and increase of MPR in the patients with ischemic heart disease. METHODS In this double-blind, placebo-controlled trial, we randomly assigned 11 patients who had symptomatic heart failure and documented myocardial ischemia to 4 weeks intravenous infusion of PGE(1) (2.5 ng/kg/min; 8 patients, age 60 ± 13 years) or saline (3 patients, age 57 ± 13 years). Dynamic (13)N-ammonia PET scans at rest and during adenosine stress were obtained at baseline and 12 weeks after treatment completion. Quantitative size/severity of perfusion defects and MPR change from baseline to follow-up PET were determined using a 17-segment model. RESULTS Compared with the control group, baseline MPR in the PGE(1) group was significantly lower (1.96 ± 0.78 vs. 2.71 ± 0.73; P < 0.001). MPR significantly improved 12 weeks after completion of PGE(1) infusion (1.96 ± 0.78 to 2.16 ± 0.77; P < 0.001). In contrast, MPR declined significantly in the placebo group (2.71 ± 0.73 to 2.01 ± 0.58, P < 0.001). CONCLUSION Four weeks of PGE(1) infusion sustained MPR improvement in patients with ischemic heart disease. This may be an attractive therapeutic approach for no-option patients with severe ischemic cardiomyopathy.

Abstract
OBJECTIVE To investigate the efficacy and safety of alprostadil cream in management of female sexual arouse disorder (FSAD), and its appropriate dose for clinical prescription. METHODS The volunteers were assigned randomly to four groups which received alprostadil cream in different dosage (500 μg, 700 μg and 900 μg) or placebo cream, respectively. The cream was applied to the clitoris and G-spot before coitus. The efficacy was assessed by comparing the satisfactory rate of sexual arousal, the score of female sexual function index (FSFI) and female sex disorder scale (FSDS) and the general appraised question (GAQ) before and after the treatment. The safety was evaluated by the adverse effects that appeared including symptoms, physical and biochemical examination. RESULTS Totally, 400 women enrolled in this study with 374 assigned to the group for efficacy evaluation and 387 cases to the group for safety analysis. No significant difference was found among the four groups in the demographic characters and sexual baseline. The increase of satisfactory percentage of sexual arousal in the four groups (placebo, 500 μg, 700 μg and 900 μg) was 22.63%, 36.67%, 34.01%, and 44.29%, respectively (P<0.05), and the increase was statistically higher in the 900 μg group than in the placebo group (P<0.0167). The elevated FSFI score above the baseline in the treatment groups (900 μg 22.89, 700 μg 21.69, and 500 μg 20.71) were higher than that in the placebo group (14.68, P<0.05), while the reduced FSDS score below the baseline (900 μg 25.97, 700 μg 21.98, and 500 μg 20.27) were higher than that of the placebo (17.60, P<0.05). No significant difference was found in the four groups in GAQ (P=0.054). The main common adverse effect was topical stimulation. No adverse effect was reported in physical and biochemical examination, electrocardiogram (ECG) or Thinprep cytologic test (TCT). CONCLUSION Alprostadil cream can treat female sexual arousal disorder effectively with the maximum effect at the dose of 900 μg and without significant adverse effect except for mild topical stimulation.

Abstract
The results of prostaglandin E1 et systemic antibacterial therapy use in 1836 patients, suffering purulent-necrotic affection of foot, were summarized. There was established, that cefuroxym constitutes the first line preparation for the ostheoarthropathy focus elimination, when the affection is limited and the patient state is stable, and meronem--for extended affection and unstable patient's state. In the pronounced ischemia of the foot the initial administration of cefepim is the most effective. For purulent-necrotic affection as a consequence of the foot wounding, erysipelas or operative intervention it is expedient to use carbapenem or meropenem. The systemic antibacterial therapy administration had promoted significant reduction of the treatment duration and improvement of its result.
