    Steroids have been widely used to treat inner-ear diseases such as sudden sensorineural hearing loss, tinnitus, and Meniere's disease. They can be given via either systemic or intratympanic (IT) injection. The purpose of the present study was to explore differences in intracochlear steroid distribution by the administration method employed (systemic vs. IT injection). Animal study. Twenty-three Sprague-Dawley rats were given fluorescein isothiocyanate-labeled dexamethasone (FITC-DEX) three times (on successive days) via intraperitoneal (IP) or IT injection. Cochlear uptake of FITC-DEX was evaluated via immunohistochemistry and flow cytometry at 6 hours, and 3 and 7 days after the final injection. FITC-DEX uptake was evident in spiral ganglion cells (SGs), the organ of Corti (OC), and the lateral walls (LWs), the basal turns of which were stained relatively prominently in both groups. Animals receiving IP injections exhibited higher FITC-DEX uptakes by the SGs and OC, whereas IT injection triggered higher-level FITC-DEX accumulation by the OC and LWs. Flow cytometry revealed that intracochlear FITC-DEX uptake by IT-injected animals was higher and more prolonged than in animals subjected to IP injections. We thus describe differences in cochlear steroid distributions after systemic and IT injections. This finding could help our understanding of the pharmacokinetics of steroids in the cochlea. NA.

    The best evidence for epidural injection appears to be in the setting of radicular pain with epidural steroid and non-steroid injections more efficacious than non-epidural injections. Studies showed the efficacy of non-particulate steroid to approach the efficacy of particulate steroid and very limited comparisons demonstrated no significant difference between epidural steroid and epidural non-steroid (local anesthetic) injection. Preliminary studies evaluating epidural injection of disease modifying anti-rheumatic drugs such etanercept and tocilizumab showed conflicting results and had significant limitations. Randomized studies support better efficacy of transforaminal injection due to greater incidence of ventral epidural spread of injectate when compared to interlaminar injection. Thus, the transforaminal approach is recommended when unilateral radicular pain is limited to one nerve root. However, the transforaminal approach is associated with greater incidence of central nervous system injury, including paraplegia, attributed to embolization of the particulate steroid. Recent studies showed that non-particulate steroids potentially last as long as particulate steroids. Therefore non-particulate steroid should be used in initial transforaminal epidural injection. Future studies should look into the role of adjunct diagnostic aids, including digital subtraction angiography, in detecting intravascular injection and the ideal site of needle placement, whether it is the safe triangle or the triangle of Kambin. Finally, the role of epidural disease -modifying antirheumatic drugs in the management of back pain needs to be better elucidated.

  3. Risk of Osteoporotic Fracture After Steroid Injections in Patients With Medicare.

    Carreon, Leah Y; Ong, Kevin L; Lau, Edmund; Kurtz, Steven M; Glassman, Steven D

    To further evaluate the relationship between steroid injections and osteoporotic fracture risk, we analyzed Medicare administrative claims data on both large-joint steroid injections (LJSIs) into knee and hip and transforaminal steroid injections (TSIs), as well as osteoporotic hip and wrist fractures. Our hypothesis was that a systemic effect of steroid injections would increase fracture risk in all skeletal locations regardless of injection site, whereas a local effect would produce a disproportionate increased risk of spine fracture with spine injection. Patients treated with an LJSI, a TSI, or an epidural steroid injection (ESI) were identified from 5% Medicare claims data. Patients under age 65 years and patients with prior osteoporotic fracture were excluded. Analyses were performed to determine fracture risk (adjusted hazard ratio) for each type of injection. Analysis of the Medicare data revealed that ESIs were associated with decreased osteoporotic spine fracture risk, but the effect was small and might not be clinically relevant. ESIs did not influence osteoporotic hip or wrist fracture risk, but LJSIs reduced the risk.

    Frozen shoulder is not an uncommon disorder, and steroid injection into the glenohumeral (GH) joint is one of the most well-known approaches for the frozen shoulder. However, their results have been varied with beneficial effects or no additional advantage. With the understanding about the pathological changes taking place in frozen shoulder and the biomechanics involved, we wanted to evaluate the short- and long-term efficacy of steroid injection by a novel three-site (NTS) injection technique and compare it with the single-site injection (SSI). This was a prospective study with 85 patients including all stages and randomized into two groups. SSI group received steroid injection through posterior approach. NTS group received the same dose of steroid in diluted doses at three sites (posterior capsule, subacromial and subcoracoid). Second sitting was repeated after 3 weeks. Both groups had received the same physiotherapy. The patients were evaluated by CONSTANT score at initial, 3 week, 6 week and 6 month. NTS group patients had significant pain relief and early improvement in activities of daily living ( p < 0.005). Both groups had improvement in shoulder movements but with NTS group, early near-normal scores were attained and sustained after 6 months. About 43% in SSI group could not attain near-normal levels and had relapses. The three-site approach to steroid instillation in frozen shoulder is a safe method and provides early recovery and better improvement in shoulder function with less relapses.

    To identify the diagnostic, therapeutic, and prognostic values of transforaminal epidural steroid injection as interventional rehabilitation for lumbar radiculopathy. Regional hospital, Hong Kong. A total of 232 Chinese patients with lumbar radiculopathy attributed to disc herniation or spinal stenosis received transforaminal epidural steroid injection between 1 January 2007 and 31 December 2011. Transforaminal epidural steroid injection. Patients' immediate response, response duration, proportion of patients requiring surgery, and risk factors affecting the responses to transforaminal epidural steroid injection for lumbar radiculopathy. Of the 232 patients, 218 (94.0%) had a single level of radiculopathy and 14 (6.0%) had multiple levels. L5 was the most commonly affected level. The immediate response rate to transforaminal epidural steroid injection was 80.2% in 186 patients with clinically diagnosed lumbar radiculopathy and magnetic resonance imaging of the lumbar spine suggesting nerve root compression. Of patients with single-level radiculopathy and multiple-level radiculopathy, 175 (80.3%) and 11 (78.6%) expressed an immediate response to transforaminal epidural steroid injection, respectively. The analgesic effect lasted for 1 to <3 weeks in 35 (15.1%) patients, for 3 to 12 weeks in 37 (15.9%) patients, and for more than 12 weeks in 92 (39.7%) patients. Of the 232 patients, 106 (45.7%) were offered surgery, with 65 (61.3%) undergoing operation, and with 42 (64.6%) requiring spinal fusion in addition to decompression surgery. Symptom chronicity was associated with poor immediate response to transforaminal epidural steroid injection, but not with duration of pain reduction. Poor response to transforaminal epidural steroid injection was not associated with a preceding industrial injury. The immediate response to transforaminal epidural steroid injection was approximately 80%. Transforaminal epidural steroid injection is a useful diagnostic, prognostic, and

    To compare the 6-week and 6-month outcome in 60 patients who received a single-dose injection of platelet-rich plasma (PRP) or steroid for subacromial impingement syndrome (SIS). 22 men and 38 women (mean age, 49.7 years) opted to receive a single-dose injection of PRP (n=30) or steroid (n=30) for SIS that had not responded to conservative treatment for >3 months. The PRP or a mixture of 1 ml 40 mg methylprednisolone and 8 ml prilocaine was administered via a dorsolateral approach through the interval just beneath the dorsal acromial edge. Both groups were instructed to perform standard rotator cuff stretching and strengthening exercises for 6 weeks. The use of non-steroid anti-inflammatory drugs was prohibited. Patients were evaluated before and 6 weeks and 6 months after treatment using the Constant score, visual analogue scale (VAS) for pain, and range of motion (ROM) of the shoulder. No local or systemic complication occurred. Improvement in the Constant score and VAS for pain at week 6 and month 6 was significantly better following steroid than PRP injection. The difference in the Constant score was greater than the mean clinically important difference of 10.4. Nonetheless, the 2 groups were comparable for improvement in ROM of the shoulder. Steroid injection was more effective than PRP injection for treatment of SIS in terms of the Constant score and VAS for pain at 6 weeks and 6 months.

    Spinal epidural lipomatosis is a rare disorder that can manifest with progressive neurological deficits. It is characterized by abnormal accumulation of unencapsulated epidural fat commonly associated with the administration of exogenous steroids associated with a variety of systemic diseases, endocrinopathies, and Cushing syndrome (Fogel et al. Spine J 5:202-211, 2005). Occasionally, spinal epidural lipomatosis may occur in patients not exposed to steroids or in patients with endocrinopathies, primarily in obese individuals (Fogel et al. Spine J 5:202-211, 2005). However, spinal lumbar epidural lipomatosis resulting from local steroid injection has rarely been reported. We report the case of a 45-year-old diabeticmore » man with claudication that was probably due to symptomatic lumbar spinal lipomatosis resulting from a single local epidural steroid injection.« less

    Background Lumbar transforaminal epidural steroid injection is a common and effective tool for managing lumbar radicular pain, although accidental intravascular injection can rarely result in paralysis. The purpose of this study is to determine the safest needle tip position for computed tomography (CT)-guided lumbar transforaminal epidural steroid injections as determined by incidence of intravascular injection. Methods Three radiologists, in consensus, reviewed procedural imaging for consecutive CT-fluoroscopic lumbar transforaminal epidural steroid injections performed during a 16-month period. Intravascular injections were identified and categorized by needle tip position, vessel type injected, intravascular injection volume and procedural phase containing the intravascular injection. Pearson chi-square and logistic regression testing were used to assess differences between groups, as appropriate. Results Intravascular injections occurred in 9% (52/606) of injections. The intravascular injection rate was significantly lower (P<0.001) for extraforaminal needle position (0%, 0/109) compared to junctional (8%, 27/319) and foraminal (14%, 25/178) needle tip positions. Of the intravascular injections, 4% (2/52) were likely arterial, 35% (18/52) were likely venous, and 62% (32/52) were indeterminate for vessel type injected. 46% (24/52) of intravascular injections were large volume, 33% (17/52) were small volume, and 21% (11/52) were trace volume. 56% (29/52) of intravascular injections occurred with the contrast trial dose, 29% (15/52) with the steroid/analgesic cocktail, and 15% (8/52) with both. Conclusions An extraforaminal needle position for CT-fluoroscopic lumbar transforaminal epidural steroid injections decreases the risk of intravascular injection and therefore may be safer than other needle tip positions.

    Persistent hiccup is uncommon, and the mechanism is poorly understood. We present the case of a 43-year-old male patient referred to the Algology department due to chronic back pain who developed what we believe a rare case of persistent hiccup secondary to caudal epidural steroid injection (CESI). The causes of hiccup are many and include electrolyte derangement, nutritional deficiencies, gastrointestinal disorders and instrumentation, cardiovascular disorders, renal impairment, central nervous system disorders, and drugs; however, the cause may be unknown. CESI is one of the treatments of back pain, in addition to various other modalities including surgical interventions. CESI has gained rapid and widespread acceptance for the treatment of lumbar and lower extremity pain. However, there are only a few well-designed, randomized, controlled studies on the effectiveness of steroid injections. Consequently, side effects should be considered. We aimed to present a persistent hiccup after CESI for chronic low back pain. PMID:28928587

    The objective of this study was to describe a patient with idiopathic supraglottic stenosis who experienced persistent disease despite multiple office-based and operative interventions, whose disease is now better controlled with scheduled serial office-based steroid injections. This is a case report and literature review. A 42-year-old female was referred for worsening supraglottic stenosis despite systemic steroids. She underwent awake tracheotomy. A thorough historical, histologic, and laboratory workup did not reveal an etiology to her stenosis. She later underwent endoscopic partial laryngectomy and was able to be decannulated. She underwent a second endoscopic partial laryngectomy two years later for worsening disease and then was managed over the next seven years with intermittent systemic steroids. Over the last year, she has undergone eight office-based steroid injections with improvement in her degree of stenosis and symptom burden. There are only four prior reported cases of idiopathic supraglottic stenosis, none of which has been managed with serial office-based steroid injections. This case report adds to the small body of literature on the management of this rare disease and proposes a new office-based treatment pathway that may help induce regression of stenosis.

    Intraarticular steroid injections are widely used in joint arthritis. However, the data regarding an association between an increased risk for arthroplasty infection after an intraarticular steroid injection are still conflicting. We conducted a meta-analysis to evaluate the evidence from relevant studies that examine the relation between intraarticular steroid injections and infection rates in subsequent joint arthroplasty and to develop GRADE based recommendations for using the steroid before arthroplasty. A systematic search of all studies published through August 2014 was conducted using the MEDLINE, EMBASE, OVID, ScienceDirect and Cochrane CENTRAL databases. The relevant studies that examined the relation between intraarticular steroid injections and infection rates in subsequent joint arthroplasty were identified. Demographic characteristics, infection rates and clinical outcomes were manually extracted from all of the selected studies. The evidence quality levels and recommendations were assessed using the GRADE system. Eight studies looking at hip and knee arthroplasties were included. Meta-analysis showed that patients with steroid injection before arthroplasty had a higher deep infection rate than patients without steroid injection (OR = 2.13, 95% CI 1.02-4.45), but no significant effect on superficial infection rate (OR = 1.75, 95% CI 0.74-4.16). The overall GRADE system evidence quality was very low, which lowers our confidence in their recommendations. Intraarticular steroid injections may lead to increased deep infection rates of subsequent joint arthroplasty but not the superficial infection rates. Due to the poor quality of the evidence currently available, further studies are still required.

    Percutaneous release (PR) of the A1 pulley is a quick, safe, and minimally invasive procedure for treating trigger fingers. The purpose of this study is to identify if PR with additional steroid injections can shorten the recovery to reach unlimited range of motion. Between January 2013 and December 2013, we included 432 trigger fingers with actively correctable triggering or severer symptoms without previous surgical release or steroid injections from two hand clinic offices (A and B). The same experienced surgeon performed PR at the office. Patients from Clinic A received PR with steroid injections and those from Clinic B received PR without steroid injections. Patients returned for follow-up 1 week, 6 weeks, and 12 weeks after the procedure. Between the steroid group and the nonsteroid group, there is no significant difference in the mean time for patients to return to normal work and the rate of residual extensor lag. Middle fingers showed a 5.09-fold chance of having a residual extensor lag over that of the other fingers. High grade trigger fingers recovered more slowly than low grade ones. The success rate of a 12-week follow-up was 98.4%. There was no significant difference between the steroid group (97.5%) and the nonsteroid group (99.1%). PR can treat trigger fingers effectively, but additional steroid injection does not provide more benefit. Some fingers showed temporary extensor lag, especially in middle fingers and high grade trigger fingers, but 85% of those will eventually reach full recovery after self-rehabilitation without another surgical release.

    Abstract To compare the effect of steroid injection and physiotherapy for patients with adhesive capsulitis of the shoulder (ACS). An electronic search was performed on Pubmed, Embase, and Cochrane library, and reference lists were also reviewed for randomized controlled trials (RCTs) comparing steroid injection and physiotherapy for patients with ACS. The quality of included studies were assessed using PEDro scale. Standardized mean differences (SMDs) and 95% confidence interval (CI) were used for comparisons. The primary outcome was functional improvement. Nine RCTs including 453 patients were identified. From 6–7 weeks to 24–26 weeks postintervention, no superiority was noted in favor of either steroid injection or physiotherapy for functional improvement (SMD 0.28; 95% CI −0.01–0.58; P = 0.06) or pain relief (SMD −0.10; 95% CI −0.70–0.50; P = 0.75). Steroid injection provided more improvement in passive external rotation at 24 to 26 weeks (3 studies, SMD 0.42; 95% CI 0.11–0.72; P = 0.007) but not at 6 to 7 weeks (4 studies, SMD 0.63; 95% CI 0.36–0.89; P = 0.32) or 12 to 16 weeks (3 studies, SMD −0.07; 95% CI −0.79–0.65; P = 0.85). Steroid injection was as safe as physiotherapy for patients with ACS (risk ratio 0.94; 95% CI 0.67–1.31). Both steroid injection and physiotherapy are equally effective for patients with ACS. One steroid injection might be the 1st choice for ACS. Results should be interpreted with caution due to the heterogeneity among the studies. PMID:27196452

    Lipomas are common benign tumours of fat cells. In most cases, surgical excision is curative and simple to perform; however, such a procedure requires general anaesthesia and may be associated with delayed wound healing, seroma formation and nerve injury in deep and intramuscular tumours. The objective of this study was to evaluate treatment of subcutaneous, subfascial or intermuscular lipomas using intralesional steroid injections in dogs. Fifteen dogs presenting with lipomas were selected for treatment with ultrasound-guided intralesional injection of triamcinolone acetonide at a dose of 40 mg/mL. Nine subcutaneous and subfascial tumours showed a complete regression. The other lipomas decreased in diameter, achieving, in some cases, remission of discomfort and regression of lameness. Steroid injection was a relatively safe and effective treatment for lipomas in dogs; only six dogs experienced polyuria/polydipsia for about 2 weeks post-treatment. PMID:23226250

    Parenterally administered steroids have been shown to affect the metabolism of glucose and to cause abnormal blood glucose levels in diabetic patients. These abnormal blood glucose levels in diabetic patients raise concerns that intra-articular steroid injections also may affect blood glucose levels. We performed a systematic review of studies examining the effect of intra-articular steroid injections on blood glucose levels in patients with diabetes mellitus. A literature search of the PubMed, EMBASE, AMED, and CINAHL databases using all relevant keywords and phrases revealed 532 manuscripts. After the application of inclusion criteria, seven studies with a total of seventy-two patients were analyzed. All studies showed a rise in blood glucose levels following intra-articular steroid injection. Four of the seven studies showed a substantial increase in blood glucose. Peak values reached as high as 500 mg/dL. The peak increase in blood glucose did not occur immediately following intra-articular steroid injection, and in some cases it took several days to occur. In many patients, post-injection hyperglycemia occurred within twenty-four to seventy-two hours. Intra-articular steroid injections may cause hyperglycemia in patients with diabetes mellitus, and patients should be warned of this complication. Diabetic patients should be advised to regularly monitor their blood glucose levels for up to a week after injection and should seek medical advice if safe thresholds are breached.

    Randomized clinical trial. To compare the effectiveness of facet joint injection versus systemic steroid in patients with a diagnosis of facet joint syndrome. The term facet joint syndrome has been used to define back pain originating from the facet joints. Treatment is mainly conservative, although interventions, including intra-articular injections and medial branch nerve blocks are used to manage facet-mediated pain. Several studies have evaluated the effectiveness of these interventions. Results of facet joint injection, however, are conflicting. Sixty subjects with a diagnosis of facet joint syndrome were enrolled in the study. They were randomized into experimental and control groups. The experimental group was administered with intra-articular injection of 6 lumbar facet joints with triamcinolone hexacetonide; the control group was administered with triamcinolone acetonide intramuscular injection of 6 lumbar paravertebral points. Visits were taken at baseline and at 1, 4, 12, and 24 weeks after interventions. Outcome measures were used: pain visual analogue scale, pain visual analogue scale during extension of the spine, Likert scale, improvement percentage scale, Roland-Morris, 36-Item Short Form Health Survey, and accountability of medications taken.Homogeneity was tested using the Student t, Pearson χ, and Mann-Whitney tests. Analysis of variance was used to analyze differences in the groups over time and the Student t test to analyze differences between groups at each time evaluation. The groups were similar at baseline. Comparisons between the groups showed, in analysis of variance analysis, an improvement in the experimental group regarding diclofenac intake and quality of life, in the "role physical" profile, assessed by 36-Item Short Form Health Survey.In the analysis at each time point, an improvement in the experimental group was also found in the Roland-Morris questionnaire, in the improvement percentage scale and in the response to treatment

    Epidural steroid injection has been used to treat low back pain for many decades. Numerous randomized trials have examined the efficacy of this approach. This review details the findings of older systematic reviews, newer randomized controlled trials, and two recent systematic reviews that examine the effectiveness of this treatment. Collectively, studies in acute radicular pain due to herniated nucleus pulposus have failed to show that epidural steroid injection reduces long-term pain or obviates the need for surgery. Similarly, there is scant evidence that epidural steroids have any beneficial effect in those with acute low back pain without leg pain or in those with chronic low back or leg pain. However, most studies have demonstrated more rapid resolution of leg pain in those who received epidural steroid injections versus those who did not. The role of epidural steroid injections in the management of acute radicular pain due to herniated nucleus pulposus is simply to provide earlier pain relief.

    We studied the effect of intratympanic steroid administration with different total injection times on hearing outcomes in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). The subjects were 191 consecutive patients (192 ears) with ISSNHL (hearing level ≥40 dB, interval between onset and treatment ≤30 days). They received systemic prednisolone (100 mg followed by tapered doses) combined with intratympanic injection of dexamethasone (4 mg/ml). Intratympanic injection was performed 4 times (days 1, 2, 4, and 7) in 92 patients (92 ears) or 2 times (days 1 and 2) in 99 patients (100 ears). The hearing outcomes were evaluated at 1 week from the start of treatment and 1 to 2 months after the completion of treatment. There was no significant difference in hearing outcomes between the 4- and 2-injection groups at either time point. Multiple regression analysis also showed that the hearing level after treatment did not depend on the total number of intratympanic steroid injections. These results indicate that a protocol using only 2 intratympanic steroid injections exerts a sufficient effect on the hearing outcomes of ISSNHL. This simplified treatment protocol would be greatly beneficial to relieve the physical and mental stress of patients.

    We report an extremely unusual iatrogenic infection of the spinal canal with Aspergillus fumigatus that resulted in intradural abscess formation following epidural steroid injection in an immunocompetent young individual. Although the imaging findings of the infection were relatively nonspecific, MR imaging not only allowed for a prompt diagnosis, but also helped in surgical localization to the intradural compartment. Complications from the use of these injections are briefly discussed.

    Current treatment options for idiopathic subglottic stenosis include endoscopic interventions, resection, and tracheotomy. Recently, serial office-based steroid injections were proposed as an alternative that may stabilize or induce regression of airway stenosis without the need for repeated operations. Procedure completion rate, pain, complications, effect on stenosis, time since the last operation, and limitations have not been described. Retrospective case series. Retrospective series of 19 patients undergoing serial office-based steroid injection for idiopathic subglottic stenosis. Outcome measures included completion rate, procedure-related pain scores, complications, percentage of airway stenosis, and time since the last operative intervention. Procedure completion rate was 98.8%. Average pain score during the procedure was 2.3 ± 1.7 on a 10-point scale. There were no immediate complications. One patient underwent awake tracheotomy 8 days after her second injection and was later decannulated. Average stenosis decreased from 35% ± 15% to 25% ± 15% (n = 16; P = .086) over the first of three injections and 40% ± 15% to 25% ± 10% to 20% ± 10% (n = 8; P = .002) for those patients completing two sets of three injections. Fourteen of 17 patients undergoing at least three injections have not returned to the operating room since the first injection. Office-based steroid injection represents a promising new treatment pathway for a disease that requires long-term management, offering a purely pharmacologic approach to a disorder that has traditionally been approached from a mechanical perspective. It is safe, well tolerated, and effective. Furthermore, it may help patients and physicians avoid repeated trips to the operating room and the associated risks. 4.

    2012-02-01

    To determine the incidence of inadvertent lumbar facet joint injection during an interlaminar epidural steroid injection (ESI). A total of 686 interlaminar lumbar ESIs were performed from January 1, 2009 to December 31, 2009. Archived images from these cases were retrospectively reviewed on the PACS. Positive cases of inadvertent lumbar facet joint injection were identified by the characteristic sigmoid-shaped contrast pattern projecting over the posterior elements on the lateral view and/or ovoid contrast projecting over the facet joints on the anteroposterior (AP) view. Eight positive events were identified (1.2%). There was no statistically significant gender or lumbar level predilection. In 3/8 of the positive cases (37.5%), the inadvertent facet joint injection was recognized by the operator. The needle was repositioned as a result, and contrast within the posterior epidural space was documented by the end of the procedure. In 5/8 of the positive cases (62.5%), the patients reported an immediate decrease in the presenting pain. The incidence of inadvertent lumbar facet joint injection during an interlaminar epidural steroid injection is low. Recognizing the imaging features of this event permits the operator to redirect the needle tip into the epidural space and/or identify the facet joint(s) as a source of the patient's presenting pain.

    Patients who present for steroid injections are not routinely screened for potential hypothalamic-pituitary-adrenal (HPA) axis suppression from previous steroid exposure. Patients often receive various steroid therapies that are not reported by the patient or recorded in available medical records. Yet, HPA axis suppression has been reported with a single intra-articular injection. An IRB-approved quality improvement questionnaire was implemented to comprehensively screen patients for risk of HPA axis suppression secondary to prior and/or concurrent corticosteroid use. This questionnaire was given to adult patients seen in a University Pain Management Clinic, who were being considered for a steroid injection, to define the extent of exposure to corticosteroids either by mouth, topically, inhaled, or systemic/local injection within the past 6 months. Two hundred patients completed the questionnaire. Eighty-nine patients (44.5%) screened positive for significant steroid exposure with a screen score of three or above. The average score for the screen positive group was 6.31 ± 3.47 (range 3-22). Women were 1.9 times more likely to screen positive than men (53.4% vs 27.5%, P < 0.0004). Otherwise, the screen positive and screen negative groups were similar in demographic characteristics (age, BMI, and diabetes status). Our results suggest that patients receive steroids from many sources and may be at risk for HPA axis suppression. Further testing is necessary to determine if these patients indeed have biochemical evidence of adrenal suppression. Utilization of a screening questionnaire might help identify patients who should be considered for HPA axis testing prior to steroid injections. Wiley Periodicals, Inc.

    We describe a patient who had an immediate, intense, localized synovitis due to intraarticular triamcinolone hexacetonide injection. The reaction was secondary to rapid intracellular ingestion of the steroid microcrystals as demonstrated by compensated polarized microscopy. We report the unique nature of this patient's response, and we review previous literature regarding "steroid flare" after intraarticular injection.

    Patients suffer significant pain during intralesional steroid injection treatment for keloids and hypertrophic scars. Vibration anesthesia has been shown to effectively and safely alleviate pain sensations, likely by reducing pain transmission from peripheral receptors to the brain. The objective was to evaluate the efficacy, safety, and patient satisfaction associated with vibration anesthesia for reducing pain during intralesional corticosteroid injection. The authors recruited 40 patients with 58 keloids who were scheduled to undergo intralesional triamcinolone acetonide (TA) injections. Half of each keloid was injected with concomitant vibration anesthesia, whereas the other half was injected without vibration anesthesia. Pain experienced by patients during both procedures was assessed according to visual analog scale (VAS) score. The authors also assessed procedure safety. The mean VAS score during intralesional TA injection therapy without vibration was 5.88 ± 2.34. By contrast, the same patients yielded a mean VAS score during intralesional TA injection therapy with vibration of 3.28 ± 1.85; the difference between the mean scores was significant (p < .05). Thirty-nine (97.5%) patients tolerated this therapy well. Vibration anesthesia is a promising option for reducing pain during keloid treatment with intralesional steroid injection.

    The use of anabolic steroids is prevalent in recreational athletes. This case report describes a young amateur bodybuilder who was referred to our outpatient clinic with jaundice and loss of appetite due to cholestatic hepatitis. Additional tests including a liver biopsy made it likely that the hepatitis was caused by the injectable anabolic steroid trenbolone enanthate. Cholestatic hepatitis may not be limited to the use of oral anabolic-androgenic steroids, as is widely assumed. Therefore, and because of other side effects, the recreational use of all forms of anabolic steroids should be discouraged.

    Open surgery is rarely justified for the initial treatment of a unicameral bone cyst, but there is some debate concerning the relative effectiveness of closed methods. This study compared the results of steroid injection with those of autologous bone marrow grafting for the treatment of unicameral bone cysts. Between 1990 and 2001, 30 patients were treated by steroid injection and 28 by grafting with autologous bone marrow. The overall success rates were 86.7% and 92.0%, respectively (p>0.05). The success rate after the initial procedure was 23.3% in the steroid group and 52.0% in those receiving autologous bone marrow (p<0.05), and the respective cumulative success rates after second injections were 63.3% and 80.0% (p>0.05). The mean number of procedures required was 2.19 (1 to 5) and 1.57 (1 to 3) (p<0.05), the mean interval to healing was 12.5 months (4 to 32) and 14.3 months (7 to 36) (p>0.05), and the rate of recurrence after the initial procedure was 41.7% and 13.3% in the steroid and in the autologous bone marrow groups, respectively (p<0.05). Although the overall rates of success of both methods were similar, the steroid group had higher recurrence after a single procedure and required more injections to achieve healing.

    Shoulder pain is very common in diabetic patients and often treated with steroid injections, with subsequent increases in blood glucose levels or the need for additional insulin being questioned. We report a case of significant and prolonged elevation of blood glucose levels and resultant insulin requirement in a type 1 diabetic man after a single 40 mg injection of triamcinolone for shoulder pain. Within 48 h, the shoulder pain as assessed by a visual analogue scale (0–10) was reduced to zero, but the elevated insulin requirements continued for 4 weeks after the injection. This finding suggests that steroid injections for shoulder pain in diabetics may not always be as safe as previously thought. We propose that medical practitioners advise their patients to monitor their glucose levels more carefully after such injections and that caution is exercised when considering administrating these injections to those who have poorly controlled blood glucose levels preinjection to avoid ketoacidosis.

    To compare the effectiveness of local steroid injection plus splinting with that of local steroid injection alone using clinical and electrophysiological parameters in patients with carpal tunnel syndrome (CTS). Randomized controlled study with 12 weeks of follow-up. Tertiary care center. Volunteer sample of patients (N=52) diagnosed with CTS. Participants were randomly assigned to the steroid injection group (n=26) or the steroid injection-plus-splinting group (n=26). Patients of both groups received ultrasound-guided steroid injection with 1mL of 10mg (10mg/mL) triamcinolone acetonide (Shincort) and 1mL of 2% lidocaine hydrochloride (Xylocaine). Participants in the second group also wore a volar splint in the neutral position while sleeping and also during daytime whenever possible for the 12-week intervention period. Participants were evaluated before the treatment and at 6 and 12 weeks after the onset of treatment. The primary outcome measure was Boston Carpal Tunnel Questionnaire scores. The secondary outcome measures were as follows: scores on the visual analog scale for pain; electrophysiological parameters, including median nerve distal motor latency, sensory nerve conduction velocity (SNCV), and compound muscle action potential and sensory nerve action potential (SNAP) amplitudes; and patient's subjective impression of improvement. At 12-week follow-up, improvements in symptom severity and functional status scores on the Boston Carpal Tunnel Questionnaire as well as SNCV and SNAP amplitudes were greater in the group that received steroid injection combined with splinting than in the group that received steroid injection alone. The between-group difference was .48 points (95% confidence interval [CI], .09-.88 points; P=.032) in the Symptom Severity Scale score, .37 points (95% CI, .06-.67 points; P=.019) in the Functional Status Scale score, 3.38m/s (95% CI, 0.54-6.22m/s; P=.015) in the SNCV amplitude, and 3.21μV (95% CI, 0.00-6.46μV; P=.025) in the SNAP

    Plantar fasciitis is the most common cause of heel pain in adults. A novel alternative medical instrument, the miniscalpel-needle (MSN), which is based on an acupuncture needle, has been recently developed in China. The objective of this study was to evaluate the effectiveness of the MSN release treatment versus that of traditional steroid injection for plantar fasciitis. Patients with plantar fasciitis were randomly assigned to 2 groups and followed up for 12 months, with 29 receiving MSN treatment and 25 receiving steroid injection treatment. The results showed that visual analog scale scores for morning pain, active pain, and overall heel pain all were decreased significantly in the MSN group from 1 to 12 months after treatment. In contrast, treatment with steroid injection showed a significant effect only at the 1-month follow-up but not at 6 or 12 months after treatment. Moreover, the MSN group achieved more rapid and sustained improvements than the steroid group throughout the duration of this study. No severe side effects were observed with MSN treatment. Our data suggest that the MSN release treatment is safe and has a significant benefit for plantar fasciitis compared to steroid injection. PMID:25114704

    Glucocorticoids have been known for years to be the most effective therapy in systemic lupus erythematosus. Their use, however, is limited by the need for high doses due to their unfavorable pharmacokinetics and biodistribution. We have previously developed a novel liposome-based steroidal (methylprednisolone hemisuccinate (MPS)) nano-drug and demonstrated its specific accumulation in inflamed tissues, as well as its superior therapeutic efficacy over that of free glucocorticoids (non-liposomal) in the autoimmune diseases, including the adjuvant arthritis rat model and the experimental autoimmune encephalomyelitis mouse model. In the present work we have evaluated the therapeutic effect of the above liposome-based steroidal (MPS) nano-drug in the MRL-lpr/lpr murine model of SLE and compared it with similar doses of the free MPS. MRL-lpr/lpr mice were treated with daily injections of free MPS or weekly injections of 10% dextrose, empty nano-liposomes or the steroidal nano-drug and the course of their disease was followed up to the age of 24 weeks. Treatment with the steroidal nano-drug was found to be significantly superior to the free MPS in suppressing anti-dsDNA antibody levels, proliferation of lymphoid tissue and renal damage, and in prolonging survival of animals. This significant superiority of our liposome based steroidal nano-drug administered weekly compared with daily injections of free methylprednisolone hemisuccinate in suppressing murine lupus indicates this glucocorticoid nano-drug formulation may be a good candidate for the treatment of human SLE. © The Author(s) 2016.

    To employ a national database to evaluate the association between intraoperative corticosteroid injection at the time of ankle arthroscopy and postoperative infection rates in Medicare patients. A national insurance database was queried for Medicare patients who underwent ankle arthroscopy, including arthroscopic removal of loose body, synovectomy, and limited or extensive debridement. Two groups were created: ankle arthroscopy with concomitant local steroid injection (n = 459) and a control group of patients who underwent ankle arthroscopy without intraoperative local steroid injection (n = 9,327). The demographics and Charlson Comorbidity Index of each group were compared. Infection rates within 6 months postoperatively were assessed using International Classification of Diseases, 9th revision, and Current Procedural Terminology codes and compared between groups using χ(2)-tests. A total of 9,786 unique patients who underwent ankle arthroscopy were included in the study. There were no statistically significant differences between the steroid injection study group and controls for the assessed infection-related variables, including gender, age group, obesity, smoking, and average Charlson Comorbidity Index. The infection rate for patients who had a local steroid injection at the time of surgery was 3.9% (18/459 patients), compared with 1.8% (168/9,327 patients) in the control group (odds ratio, 2.2; 95% confidence interval, 1.4 to 3.7; P = .002.) The majority of this difference was noted between the 65 and 79 years age groups. The use of intraoperative intraarticular corticosteroid injection at the time of ankle arthroscopy in Medicare patients is associated with significantly increased rates of postoperative infection compared with controls without intraoperative steroid injections.

The prospective study was conducted at Mayo Hospital, Lahore, from January 2008 to March 2014, and comprised patients diagnosed radiologically as a case of unicameral bone cyst. The patients were divided into two groups, with group 1 being treated with bone marrow aspiration injection, while group 2 was given steroids injection. Aspiration of bone marrow was done from tibial tuberosity. The 30 patients in the study were divided into two groups of 15(50%) each. In group 1, 8(53.34%) patients and in group 2, 3 (20%) patients achieved healing after the first injection (p<0.05), while overall success rates were 13(86.67%) in group 1, and 11(73.33%) in group 2 (p> 0.05). The mean number of procedures required in group 1 was 1.57± 0.495 (range: 01-3) and for 2.19 ± 1.076 (range: 1-5) in group 2 (p<0.05), and mean interval-to-healing was 14.3 months ± 8.705 (range: 7-36) for group 1 and 12.5 months ± 7.88 (range: 4-32) for group 2 (p> 0.05). Bone marrow aspiration injection was better than steroids in treating unicameral bone cyst.

    Bertolotti's syndrome (BS) refers to the possible association between the congenital malformation lumbosacral transitional vertebra (LSTV), and low back pain (LBP). Several treatments have been proposed including steroid injections, resections of the LSTV, laminectomy, and lumbar spinal fusion. The aim of this review was to compare the clinical outcomes in previous trials and case reports for these treatments in patients with LBP and LSTV. A PubMed search was conducted. We included English studies of patients diagnosed with LSTV treated with steroid injection, laminectomy, spinal fusion or resection of the transitional articulation. Of 272 articles reviewed 20 articles met the inclusion criteria. Their level of evidence were graded I-V and the clinical outcomes were evaluated. Only 1 study had high evidence level (II). The remainders were case series (level IV). Only 5 studies used validated clinical outcome measures. A total of 79 patients were reported: 31 received treatment with steroid injections, 33 were treated with surgical resection of the LSTV, 8 received lumbar spinal fusion, and 7 cases were treated with laminectomy. Surgical management seems to improve the patient's symptoms, especially patients diagnosed with "far out syndrome" treated with laminectomy. Clinical outcomes were more heterogenetic for patient's treated with steroid injections. The literature regarding BS is sparse and generally with low evidence. Non-surgical management (e.g., steroid injections) and surgical intervention could not directly be compared due to lack of standardization in clinical outcome. Generally, surgical management seems to improve patient's clinical outcome over time, whereas steroid injection only improves the patient's symptoms temporarily. Further studies with larger sample size and higher evidence are warranted for the clinical guidance in the treatment of BS. © The Authors, published by EDP Sciences, 2017.

    Background Infrequent but serious complications of transforaminal epidural steroid injection (TFESI) occur due to inadvertent intravascular injections. A few studies reported that the different needle types can influence on the occurrences of intravascular incidence in TFESI. This study prospectively evaluated whether short-bevel needle can reduce the incidences of intravascular injection of TFESI compared to long-bevel needles. Methods From March 2013 to December 2013, 239 consecutive patients were enrolled and received 249 fluoroscopically guided TFESI using the classic technique. Confirmation of intravascular spread was done initially with real time fluoroscopy and then with digital subtraction angiography method in a same patient. Injection technique for TFESI was the same for both short-bevel and long-bevel needle types. Results The incidences of intravascular injections with the long-bevel and short-bevel needles were 15.0% (21/140) and 9.2% (4/140), respectively. More than half of intravascular injections occurred simultaneously with epidural injections (8.0%, 20/249). There were no statistically significant differences between the long-bevel and the short-bevel needles in the rates of intravascular injections (P = 0.17). Conclusions Short-bevel needles did not demonstrate any benefits in reducing the incidence of intravascular injection. PMID:25302096

    The aim of this study was to determine 1) if repeat lumbar transforaminal epidural steroid injections (TFESIs) resulted in recovery of pain relief, which has waned since an index injection, and 2) if cumulative benefit could be achieved by repeat injections within 3 months of the index injection. Retrospective observational study with statistical modeling of the response to repeat TFESI. Academic radiology practice. Two thousand eighty-seven single-level TFESIs were performed for radicular pain on 933 subjects. Subjects received repeat TFESIs >2 weeks and <1 year from the index injection. Hierarchical linear modeling was performed to evaluate changes in continuous and categorical pain relief outcomes after repeat TFESI. Subgroup analyses were performed on patients with <3 months duration of pain (acute pain), patients receiving repeat injections within 3 months (clustered injections), and in patients with both acute pain and clustered injections. Repeat TFESIs achieved pain relief in both continuous and categorical outcomes. Relative to the index injection, there was a minimal but statistically significant decrease in pain relief in modeled continuous outcome measures with subsequent injections. Acute pain patients recovered all prior benefit with a statistically significant cumulative benefit. Patients receiving clustered injections achieved statistically significant cumulative benefit, of greater magnitude in acute pain patients. Repeat TFESI may be performed for recurrence of radicular pain with the expectation of recovery of most or all previously achieved benefit; acute pain patients will likely recover all prior benefit. Repeat TFESIs within 3 months of the index injection can provide cumulative benefit. Wiley Periodicals, Inc.

    To evaluate percutaneous computed tomography (CT)-guided intracystic and intra-articular steroid injections for the treatment of lumbar facet joint cyst causing radicular pain. A single-centre prospective study involving 120 consecutive patients with symptomatic lumbar facet joint cyst-induced radicular pain was done (72 women, 48 men). The average age was 68.2 years (52-84). Patients were treated by percutaneous CT-guided intracystic and intra-articular steroid injections. The clinical course of nerve root pain was evaluated after 1 day, and 1, 3 and 6 months, with long-term follow-up after 12 months. Patient follow-ups in our series show supportive results: within 120 patients, 54% of patients were satisfied with a long-lasting result from the first intra-cystic and intra-articular steroid injections (n = 65), while 20.8% were satisfied with a long-lasting result from a second intervention. Combining these two results shows that 75% of patients were satisfied with a long-lasting result. Our results showed that percutaneous treatment of vertebral lumbar facet joint cysts by double injections is an effective and economic therapeutic technical management among 75% of our patients. Thus we recommend that it should be considered as a first choice of treatment. Lumbar facet joint cysts are a common feature of back and radicular pain. They may be treated effectively by interventional radiologists using CT guidance. Percutaneous treatment using double injections can save surgery in 75% of patients.

    Retrospective evaluation of long-term effectiveness of the steroid injections treatment in patients with unicameral bone cysts (UBC). From January 1993 to April 2005, 23 children affected by proximal humeral UBC were evaluated according to the Neer-Cole classification system and treated with serial methylprednisolone acetate's injections. The patients were followed up at 1, 3, 6 and 12 months and then every year until the adolescence. After treatment, in 15 out of 23 patients (65.2%), the humeral cysts were referred, respectively, as Grade 1 and in four as Grade 2. In 4 patients, a refracture occurred. Statistical analysis showed an overall good response in 82.6% of patients at the end of the follow-up. Minor complication including skin discoloration accounted for 13.04%. The steroid injections showed to be an alternative excellent treatment for UBC, with complete healing of the lesions in the majority of cases. This procedure is not expensive, mini-invasive, with low surgical risk and short hospitalization.

    From the perspective of a multidisciplinary team, the authors describe the first reported use of ultrasound guidance for steroid injection into the pisotriquetral joint to relieve wrist pain of a person with spinal cord injury undergoing acute inpatient rehabilitation. Musculoskeletal ultrasound guidance was used to improve the accuracy of a corticosteroid injection of the pisotriquetral joint and the basal thumb in a 70-year-old man with paraplegia experiencing multifocal degenerative wrist pain. There was no bleeding or bruising after the injections, and the patient reported complete pain resolution 1 wk after the injections, which continued for over 1 yr. A multidisciplinary team was key in diagnosis, selection of treatment, and evaluation of treatment effect. Corticosteroid injection of the pisotriquetral joint under ultrasound guidance can be used as a treatment modality for managing wrist pain stemming from that joint. Further investigation and studies evaluating the use of ultrasound versus other imaging modalities for injection of the wrist are indicated.

    Purpose: The purpose of this study was to conduct a randomized trial of radiation therapy for plantar fasciitis and to compare radiation therapy with local steroid injections. Methods and Materials: Between March 2013 and April 2014, 128 patients with plantar fasciitis were randomized to receive radiation therapy (total dose of 6.0 Gy applied in 6 fractions of 1.0 Gy three times a week) or local corticosteroid injections a 1 ml injection of 40 mg methylprednisolone and 0.5 ml 1% lidocaine under the guidance of palpation. The results were measured using a visual analog scale, a modified von Pannewitz scale, andmore » a 5-level function score. The fundamental phase of the study was 3 months, with a follow-up period of up to 6 months. Results: The median follow-up period for all patients was 12.5 months (range, 6.5-18.6 months). For the radiation therapy patients, the median follow-up period was 13 months (range, 6.5-18.5 months), whereas in the palpation-guided (PG) steroid injection arm, it was 12.1 months (range, 6.5-18.6 months). After 3 months, results in the radiation therapy arm were significantly superior to those in the PG steroid injection arm (visual analog scale, P<.001; modified von Pannewitz scale, P<.001; 5-level function score, P<.001). Requirements for a second treatment did not significantly differ between the 2 groups, but the time interval for the second treatment was significantly shorter in the PG steroid injection group (P=.045). Conclusion: This study confirms the superior analgesic effect of radiation therapy compared to mean PG steroid injection on plantar fasciitis for at least 6 months after treatment.« less

    The purpose of this study was to conduct a randomized trial of radiation therapy for plantar fasciitis and to compare radiation therapy with local steroid injections. Between March 2013 and April 2014, 128 patients with plantar fasciitis were randomized to receive radiation therapy (total dose of 6.0 Gy applied in 6 fractions of 1.0 Gy three times a week) or local corticosteroid injections a 1 ml injection of 40 mg methylprednisolone and 0.5 ml 1% lidocaine under the guidance of palpation. The results were measured using a visual analog scale, a modified von Pannewitz scale, and a 5-level function score. The fundamental phase of the study was 3 months, with a follow-up period of up to 6 months. The median follow-up period for all patients was 12.5 months (range, 6.5-18.6 months). For the radiation therapy patients, the median follow-up period was 13 months (range, 6.5-18.5 months), whereas in the palpation-guided (PG) steroid injection arm, it was 12.1 months (range, 6.5-18.6 months). After 3 months, results in the radiation therapy arm were significantly superior to those in the PG steroid injection arm (visual analog scale, P<.001; modified von Pannewitz scale, P<.001; 5-level function score, P<.001). Requirements for a second treatment did not significantly differ between the 2 groups, but the time interval for the second treatment was significantly shorter in the PG steroid injection group (P=.045).

    Lower back and extremity pain in the amputee patient can be challenging to classify and treat. Radicular compression in a patient with lower limb amputation may present as or be superimposed upon phantom limb pain, creating diagnostic difficulties. Both patients and physicians classically find it difficult to discern phantom sensation from phantom limb pain and stump pain; radicular compression is often not considered. Many studies have shown back pain to be a significant cause of pain in lower limb amputees, but sciatica has been rarely reported in amputees. We present a case of L4/5 radiculitis in an above-knee amputee presenting as phantom radiculitis. Our patient is a 67 year old gentleman with new onset 10/10 pain in a phantom extremity superimposed upon a 40 year history of previously stable phantom limb pain. MRI showed a central disc herniation at L4/5 with compression of the traversing left L4 nerve root. Two fluoroscopically guided left transforaminal epidural steroid injections at the level of the L4 and L5 spinal nerve roots totally alleviated his new onset pain. At one year post injection, his phantom radiculitis pain was completely gone, though his underlying phantom limb pain remained. Lumbar radiculitis in lower extremity amputee patients may be difficult to differentiate from baseline phantom limb pain. When conservative techniques fail, fluoroscopically guided spinal nerve injection may be valuable in determining the etiology of lower extremity pain. Our experience supports the notion that epidural steroid injections can effectively treat phantom lumbar radiculitis in lower extremity amputees.

    Controversy exists regarding the efficacy of ligament prolotherapy in alleviating sacroiliac joint pain. The inconsistent success rates reported in previous studies may be attributed to variability in patient selection and techniques between studies. It was hypothesized that intra-articular prolotherapy for patients with a positive response to diagnostic block may mitigate the drawbacks of ligament prolotherapy. The purpose of this study was to evaluate the efficacy and long-term effectiveness of intra-articular prolotherapy in relieving sacroiliac joint pain, compared with intra-articular steroid injection. This was a prospective, randomized, controlled trial. The study was conducted at an outpatient pain medicine clinic at Chonnam National University Hospital in Gwang-ju, Korea. The study included patients with sacroiliac joint pain, confirmed by ≥50% improvement in response to local anesthetic block, lasting 3 months or longer, and who failed medical treatment. The treatment involved intra-articular dextrose water prolotherapy or triamcinolone acetonide injection using fluoroscopic guidance, with a biweekly schedule and maximum of three injections. Pain and disability scores were assessed at baseline, 2 weeks, and monthly after completion of treatment. The numbers of recruited patients were 23 and 25 for the prolotherapy and steroid groups, respectively. The pain and disability scores were significantly improved from baseline in both groups at the 2-week follow-up, with no significant difference between them. The cumulative incidence of ≥50% pain relief at 15 months was 58.7% (95% confidence interval [CI] 37.9%-79.5%) in the prolotherapy group and 10.2% (95% CI 6.7%-27.1%) in the steroid group, as determined by Kaplan-Meier analysis; there was a statistically significant difference between the groups (log-rank p < 0.005). Intra-articular prolotherapy provided significant relief of sacroiliac joint pain, and its effects lasted longer than those of steroid

    Osteogenesis imperfecta, also known as 'brittle bone disease', is a genetic connective tissue disease. It is characterized by bone fragility and osteopenia (low bone density). In this case, a 57-year old female presented to the University Hospital of the West Indies (UHWI), Physical Medicine and Rehabilitation Clinic with left low back pain rated 6/10 on the numeric rating scale (NRS). Clinically, the patient had sacroiliac joint mediated pain although X-rays did not show the sacroiliac joint changes. Fluoroscopy-guided left sacroiliac joint steroid injection was done. Numeric rating scale and Oswestry Disability Index (ODI) questionnaire were used to evaluate outcome. This was completed at baseline, one week follow-up and at eight weeks post fluoroscopy-guided sacroiliac joint steroid injection. Numeric rating scale improved from 6/10 before the procedure to 0/10 post procedure, and ODI questionnaire score improved from a moderate disability score of 40% to a minimal disability score of 13%. Up to eight weeks, the NRS was 0/10 and ODI remained at minimal disability of 15%. Fluoroscopy-guided sacroiliac joint injection is a known diagnostic and treatment method for sacroiliac joint mediated pain. To our knowledge, this is the first case published on the use of fluoroscopy-guided sacroiliac joint steroid injection in the treatment of sacroiliac joint mediated low back pain in a patient with osteogenesis imperfecta.

    Background Tennis elbow is an overuse injury affecting people performing repetitive forearm movements. It is a soft tissue disorder that causes significant disability and pain. The aim of the study was to establish that an intramuscular steroid injection is effective in the short-term pain relief and functional improvement of tennis elbow. The severity of pain at the injection site was monitored to determine whether the intramuscular injection is better tolerated than the intralesional injection. Methods and results 19 patients, who had no treatment for tennis elbow in the preceding 3 months, were recruited from Whipps Cross University Hospital, London, and were randomised to receive either 80 mg of intramuscular Depo-Medrone or 40 mg of intralesional Depo-Medrone injection. Blinding proved difficult as the injection sites differed and placebo arms were not included in the study. A Patient-Rated Tennis Elbow Evaluation (PRTEE) Questionnaire and a 10-point Likert scale were used to assess primary outcome. Six weeks after the treatment, there was a reduction in pain, improvement in function and total PRTEE scores in both intramuscular and intralesional groups (p=0.008) using a 95% CI for mean treatment difference of −26 to +16 points. A statistically significant result (p=0.001) in favour of intramuscular causing less pain at the injection site was noted. Conclusion Non-inferiority of intramuscular to intralesional injections was not confirmed; however, the intramuscular injection proved to be effective in reducing tennis elbow-related symptoms and was found less painful at the site of injection at the time of administration.

    Epstein, Nancy E.

    2013-01-01

    Background: Multiple type of spinal injections, whether epidural/translaminar or transforaminal, facet injections, are offered to patients with/without surgical spinal lesions by pain management specialists (radiologists, physiatrists, and anesthesiologists). Although not approved by the Food and Drug Administration (FDA), injections are being performed with an increased frequency (160%), are typically short-acting and ineffective over the longer-term, while exposing patients to major risks/complications. Methods: For many patients with spinal pain alone and no surgical lesions, the “success” of epidural injections may simply reflect the self-limited course of the disease. Alternatively, although those with surgical pathology may experience transient or no pain relief, undergoing these injections (typically administered in a series of three) unnecessarily exposes them to the inherent risks, while also delaying surgery and potentially exposing them to more severe/permanent neurological deficits. Results: Multiple recent reports cite contaminated epidural steroid injections resulting in meningitis, stroke, paralysis, and death. The Center for Disease Control (CDC) specifically identified 25 deaths (many due to Aspergillosis), 337 patients sickened, and 14,000 exposed to contaminated steroids. Nevertheless, many other patients develop other complications that go unreported/underreported: Other life-threatening infections, spinal fluid leaks (0.4-6%), positional headaches (28%), adhesive arachnoiditis (6-16%), hydrocephalus, air embolism, urinary retention, allergic reactions, intravascular injections (7.9-11.6%), stroke, blindness, neurological deficits/paralysis, hematomas, seizures, and death. Conclusions: Although the benefits for epidural steroid injections may include transient pain relief for those with/without surgical disease, the multitude of risks attributed to these injections outweighs the benefits.

    Most patients with Crohn's disease present with either terminal ileal or colonic disease, with 70% requiring surgery by 10 years after diagnosis. Recurrent stricturing at the anastomotic site is common, often symptomatic and can require re-operation with its inherent risks. Balloon dilation has been shown to provide good symptom relief from such strictures. However, repeat dilations may be required, and further surgical intervention to an anastomotic stricture is needed in up to 30% of cases. Injection of corticosteroids has been suggested as an adjunct to dilation in order to improve outcomes. This paper reviews the current literature on the use of intralesional steroid injections following endoscopic balloon dilation of anastomotic and de novo Crohn's strictures. There have been only two randomised placebo controlled trials and five small non-controlled or retrospective studies. Study numbers vary from 10 to 29 patients. The two randomised trials conflict in their conclusions and numbers are small in these studies. Currently therefore, no firm support can be given to the routine use of intralesional steroid injections. PMID:28839732

    Transforaminal epidural steroid injection (TFESI) is a commonly used interventional pain management procedures to treat radicular leg pain. Although most reported complications of TFESI are minor, serious morbidity has also been demonstrated including spinal cord infarction, paraplegia, and quadriparesis. Suggested mechanisms include direct vascular injury or intravascular injection of particulate steroid. We compared 2 different needle types, Whitacre and Quincke type needles, with regard to intravascular injection rate with total procedure time and the amount of radiation during lumbar TFESI. Prospective, randomized trial. An interventional pain management practice in South Korea. After Institutional Review Board approval, 149 patients undergoing lumbar TFESI for radicular leg pain were randomly assigned to one of 2 needle groups (Whitacre needle or Quincke type needle). After final confirmation of intravascular injection with digital subtraction angiography, total procedure time and amount of radiation exposure during TFESI were measured. The overall incidence of intravascular injection was 10.4% (28/269). We analyzed the overall incidence of intravascular injection according to the 2 different needle types. The incidence of intravascular injection of the Whitacre needle was 5.4% (8/146), whereas the incidence of intravascular injection of the Quincke needle was 16.2% (20/123). Total procedure time and amount of radiation required to complete the TFESI in the Whitacre and Quincke needle groups was 168.4 ± 57.9 (seconds) and 33.4 ± 15.9 (cGy/cm2), 131.9 ± 46.0 (seconds) and 33.2 ± 15.8 (cGy/cm2), respectively. The physician who performed the TFESI was not blinded to the type of needle for detecting intravascular injection. This study was focused on lumbar TFESI, however, most TFESIs are performed at the L4-5 or L5-S1 level. The Whitacre needle had the benefit of reducing the incidence of intravascular injection with minimal differences in technical

    Most cases of non-necrotising scleritis can be successfully treated with non-steroidal anti-inflammatory drugs. If these are ineffective, then high-dose systemic corticosteroids, with all their attendant side-effects, are usually required. We have used orbital floor injections of depot steroid in the management of nine patients with non-necrotising scleritis in an attempt to avoid the use of systemic steroids, or to allow the dose of steroids to be reduced while maintaining disease control. A temporary reduction in inflammation was achieved in all cases, which allowed the use of systemic steroids to be avoided altogether in two patients and delayed in the others. Non-steroidal anti-inflammatory drugs and systemic corticosteroids remain the mainstay of treatment for non-necrotising scleritis, but orbital floor injections may be a useful adjunct in certain cases.

    Plantar fasciitis is a common cause of heel pain. Considering different interventions which are applied for patients with plantar fasciitis, dry needling is proposed as a new modality of treatment recently. The aim of this study is to evaluate the effectiveness of dry needling versus steroid injection for plantar fasciitis. Sixty-six patients were recruited to this single-blind clinical trial study. Participants were randomly allocated to receive 1 ml (40 mg) of Depo-Medrol (methylprednisolone acetate) or dry needling. They were followed up for 12 months and monitored for total perception of pain using the visual analogue scale (VAS), with data obtained in baseline and at three weeks, six weeks, three months, six months and one year after treatment. Mean VAS score before treatment was 6.96 ± 0.87 for the steroid group and 6.41 ± 0.83 for the dry-needling group (P value = 0.54). Steroid injection reduced VAS scores rapidly until three weeks after treatment compared with dry needling (0.32 ± 0.71 and 3.47 ± 1.32, respectively; P value < 0.001). However, patients who were underwent dry needling reported lower VAS scores at the end of follow-up compared with the steroid group (0.69 ± 0.93 and 2.09 ± 1.58, respectively; P value = 0.004). Over the long term, 82.3% and 17.6% of changes in pain were contributed to time since treatment and treatment method, respectively (P values < 0.001). Steroid injection can palliate plantar heel pain rapidly but dry needling can provide more satisfactory results for patients with plantar fasciitis in the long term.

    To examine associations between imaging characteristics of compressive lesions and patient outcomes after lumbar transforaminal epidural steroid injections (TFESIs) stratified by steroid formulation (solution versus suspension). Retrospective observational study, academic radiology practice. A 516-patient sample was selected from 2,634 consecutive patients receiving lumbar TFESI for radicular pain. The advanced imaging study(s) preceding sampled TFESI were reviewed. Compressive lesions were described by a) nature of the lesion [disc herniation, fixed stenosis, synovial cyst, epidural fibrosis, no lesion] b) degree of neural compression [4 part scale], and c) presence of a tandem lesion. Associations between 2-month categorical outcomes (responder rates for pain, functional recovery) and imaging characteristics, stratified by steroid formulation, were examined with chi-squared tests of categorical outcomes and multivariable logistic regression models. Disc herniation patients had more responders for functional recovery than patients with fixed lesions (54% versus 38%, P = 0.01). Patients with fixed lesions receiving steroid solution (dexamethasone) had more responders for pain relief, with a similar trend for functional recovery, than patients receiving suspensions (59% versus 40%, P = 0.01). Outcomes for patients with fixed lesions treated with dexamethasone were not statistically different from those for disc herniation patients. Patients with single compressive lesions had more responders than those with tandem lesions (55% versus 41%, P = 0.03). In the entire sample, outcomes for disc herniations were more favorable than for fixed lesions. However, fixed lesions treated with dexamethasone had outcomes indistinguishable from disc herniations. Single lesions had better outcomes than tandem lesions. © 2016 American Academy of Pain Medicine. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

    Endoscopic submucosal dissection (ESD) of large gastric lesions results in an extensive artificial ulcer that can lead to marked gastric deformity. The aim of the current study was to evaluate therapeutic efficacy in the prevention of gastric deformity of local triamcinolone acetonide (TCA) injection into the extensive artificial ulcer following ESD. A total of 45 patients who were diagnosed with early gastric cancer were enrolled. Patients were randomly assigned by the sealed-envelope randomization method to either local TCA injections (n = 21) or sham-control (n = 20) groups. Two clips were placed at the two maximum outer edges of the artificial ulcer after the lesion had been resected (Day 0). Local TCA injections were performed on postoperative Day 5 and Day 12. The distance between the two clips was measured by endoscopic measuring forceps on Days 5, 12, 30, and 60. Granulation formation and gastric deformity were evaluated by visual analog scale (VAS) on Days 30 and 60. Local TCA injection did not alter clip-to-clip distance on postoperative Day 60, and formation of flat granulation tissue over the ulcer was followed by regenerative mucosa without any gastric deformity. The sham-control group showed significant shortening of clip-to-clip distance compared with the local steroid-injected group and protruded forms of granulation tissue with mucosal convergence. Histological evaluation revealed prominent growth of neovessels, swelling, and marked increases in endothelial cells in the local steroid-injected group compared with the sham-control group. Local steroid injection into the floor of a post-ESD artificial ulcer promotes the formation of granulation tissue at an early stage of the healing process leading to regeneration of gastric mucosa without mucosal convergence or gastric deformity. © Georg Thieme Verlag KG Stuttgart · New York.

    The aims of this study were to: (a) Identify tendon sheaths most commonly treated with steroid injections in a pediatric patient population with Juvenile Idiopathic Arthritis (JIA); (b) Describe technical aspects of the procedure; (c) Characterize sonographic appearance of tenosynovitis in JIA; (d) Assess agreement between clinical request and sites injected. This was a 10 year single-center retrospective study (May 2006-April 2016) of patients with JIA referred by Rheumatology for ultrasound-guided tendon sheath injections. Patient demographics, clinical referral information, sonographic appearance of the tendon sheaths and technical aspects of the procedure were analyzed. There were 308 procedures of 244 patients (75% female, mean age 9.6 years) who underwent a total of 926 tendon sheath injections. Ankle tendons were most commonly injected (84.9%), specifically the tendon sheaths of tibialis posterior (22.3%), peroneus longus (20%) and brevis (19.7%). The majority of treated sites (91.9%) showed peritendinous fluid and sheath thickening on ultrasound. There were 2 minor intra-procedure complications without sequelae. A good agreement between clinical request and sites injected was observed. Ultrasound-guided tendon sheath injections with steroids are used frequently to treat patients with JIA. It is a safe intervention with a high technical success rate. The ankle region, specifically the medial compartment, is the site most commonly injected in this group of patients. The most common sonographic finding is peritendinous fluid and sheath thickening. These findings might assist clinicians and radiologists to characterize and more effectively manage tenosynovitis in patients with JIA.

    Treatment of pyoderma gangrenosum complicating ulcerative colitis has in the past been frustrating and usually unsuccessful, frequently resulting in colectomy. Intralesional steroid therapy has been used off and on in a few patients, but the treatment is not widely known to gastroenterologists. We report two patients successfully treated for early pyoderma gangrenosum by intralesional injection of triamcinolone acetonide (Kenalog, 40 mg injection) together with conventional doses of systemic steroids. A single series of injections was sufficient to bring about healing of the lesions in both patients. The treatment permitted early discharge of patients from the hospital, and the skin lesions were completely healed within 2 months. The lesions have not recurred in follow-up examinations of 11/2 and 21/2 years, respectively. We hope that other physicians will find this approach equally effective.

    To compare the effects of 2 different injection sites of low doses of botulinum toxin type A with steroid in treating lateral epicondylalgia. Double-blind, randomized, active drug-controlled trial. Tertiary medical center. Patients with lateral epicondylalgia for >6 months were recruited from a hospital-based outpatient population (N=26). A total of 66 patients were approached, and 40 were excluded. No participant withdrew because of adverse effects. Patients were randomly assigned into 3 groups: (1) botulinum toxin epic group (n=8), who received 20U of botulinum toxin injection into the lateral epicondyle; (2) botulinum toxin tend group (n=7), who received 20U of botulinum toxin injected into tender points of muscles; and (3) steroid group (n=11), who received 40mg of triamcinolone acetonide injected into the lateral epicondyle. A visual analog scale, a dynamometer, and the Patient-Rated Tennis Elbow Evaluation were used to evaluate the perception of pain, maximal grip strength, and functional status, respectively. Outcome measures were assessed before intervention and at 4, 8, 12, and 16 weeks after treatment. The primary outcome measure was a visual analog scale. At 4 weeks after injection, the steroid group was superior to the botulinum toxin tend group in improvement on the visual analog scale (P=.006), grip strength (P=.03), and Patient-Rated Tennis Elbow Evaluation (P=.02). However, these differences were not observed at the 8-, 12-, and 16-week follow-up assessments. There was no significant difference between the steroid and botulinum toxin epic groups. Injections with botulinum toxin and steroid effectively reduced pain and improved upper limb function in patients with lateral epicondylalgia for at least 16 weeks. The onset of effect was earlier in the steroid and botulinum toxin epic groups than in the botulinum toxin tend group. Copyright © 2016 American Congress of Rehabilitation Medicine.

    Transforaminal epidural steroid injections (TFESI) have demonstrated efficacy and effectiveness in treatment of radicular pain. Despite little evidence of efficacy/effectiveness, interlaminar epidural steroid injections (ILESI) are advocated by some as primary therapy for radicular pain due to purported greater safety. To assess immediate and delayed adverse event rates of TFESI and ILESI injections at three academic medical centers utilizing International Spine Intervention Society practice guidelines. Quality assurance databases from a Radiology and two physical medicine and rehabilitation (PM&R) practices were interrogated. Medical records were reviewed, verifying immediate and delayed adverse events. There were no immediate major adverse events of neurologic injury or hemorrhage in 16,638 consecutive procedures in all spine segments (14,956 TFESI; 1,682 ILESI). Vasovagal reactions occurred in 1.2% of procedures, more frequently (P = 0.004) in TFESI (1.3%) than ILESI (0.5%). Dural punctures occurred in 0.06% of procedures, more commonly after ILESI (0.2% vs 0.04%, P = 0.006). Delayed follow up on PM&R patients (92.5% and 78.5, next business day) and radiology patients (63.1%, 2 weeks) identified no major adverse events of neurologic injury, hemorrhage, or infection. There were no significant differences in delayed minor adverse event rates. Central steroid response (sleeplessness, flushing, nonpositional headache) was seen in 2.6% of both TFESI and ILESI patients. 2.1% of TFESI and 1.8% of ILESI patients reported increased pain. No long-term sequelae were seen from any immediate or delayed minor adverse event. Both transforaminal and ILESI are safely performed with low immediate and delayed adverse event rates when informed by evidence-based procedural guidelines. By demonstrating comparable safety, this study suggests that the choice between ILESI and TFESIs can be based on documented efficacy and effectiveness and not driven by safety concerns.

    Cervical necrotizing fasciitis is a rare, rapidly progressive, severe bacterial infection of the soft tissues of the neck. Uncommonly, it may descend into the mediastinum. We describe a case of descending necrotizing mediastinitis in a young man, where there was diagnostic confusion and delay, with an eventual fatal outcome. A steroid injection for neck pain is thought to be the source of infection. In this case, the signs of mediastinitis were initially masked, and the diagnosis delayed until cardiopulmonary arrest occurred. Early recognition with a low threshold for computed tomography (CT) scanning is essential. Aggressive multidisciplinary therapy with mediastinal drainage is mandatory.

    Background Epidural injections of anesthetic with or without steroids are widely used for treating lumbar spinal stenosis, a common cause of chronic low back pain, but there is a lack of rigorous data comparing the effectiveness of epidural injections of anesthetic with and without steroids. This meta-analysis presents a current, comprehensive picture of how epidural injections of anesthetic with steroids compare with those using local anesthetic alone. Methods PubMed, Embase, Web of Science, and Cochrane Library databases were searched from their inception through February 5, 2015. Weight mean difference, risk ratio, and 95% confidence intervals were calculated. A random effects model or fixed effects model was used to pool the estimates, according to the heterogeneity between the included studies. Results We included 13 randomized controlled trials, involving 1,465 patients. Significant pain relief (≥50%) was demonstrated in 53.7% of patients administered with epidural injections of anesthetic with steroids (group 1) and in 56.4% of those administered with local anesthetic alone (group 2). Patients showed a reduction in numeric rating scale pain score of 3.7 and 3.6 in the two groups, respectively. Significant functional improvement was achieved in 65.2% of patients in group 1 and 63.1% of patients in group 2, with Oswestry Disability Index reductions of 13.8 and 14.5 points, respectively. The overall number of injections per year was 3.2±1.3 and 3.4±1.2 with average total relief per year of 29.3±19.7 and 33.8±19.3 weeks, respectively. The opioid intakes decreased from baseline by 12.4 and 7.8 mg, respectively. Among the outcomes listed, only total relief time differed significantly between the two groups.

    We report on a patient with postsurgical cystoid macular edema (CME) after phacoemulsification and multifocal intraocular lens (MIOL) implantation. At first, there was a very good reaction to intravitreal triamcinolone, inducing complete regression of the edema without increasing intraocular pressure (IOP). One year later the patient suffered from retinal detachment and was treated with vitrectomy, laser, and gas tamponade. Afterward, he developed macular pucker with edema. After surgical treatment with pucker peeling and intravitreal triamcinolone, the patient showed a steroid response and an increase IOP. Postoperatively, there was a recurrence of CME. A coincidental administration of a steroid injection intramuscularly by the general practitioner achieved a prompt reduction of the CME without increasing IOP. This case shows that an initially good reaction to triamcinolone without increasing IOP does not rule out a future steroid response, and that a potential treatment option for CME in patients with a known steroid response could consist of intramuscularly injected steroids.

    To examine the effect of steroid therapy on the volume estimates and blood flow characteristics of childhood periorbital capillary haemangiomas. Children at risk of amblyopia due to periorbital haemangiomas were treated with intralesional steroid injections (between 1 and 4 courses) and serial assessment of the volume and blood-flow characteristics of the lesions measured using colour Doppler ultrasonography. The characteristics of the haemangiomas in these children were compared with a cohort of untreated cases. Eight of nine treated children were female, this proportion being significantly different from the equal sex distribution of an untreated cohort (p < 0.05). All children in the steroid-treated group presented within 1 month of birth, compared to the untreated children, who presented at an average of 2.1 months of age (range 0-14, median 2.9 months) (p = 0.04) and they required significantly longer follow-up in the Orbital service (mean 65 months, range 26-105), compared with an average of 35 months (range 4-92, median 23) in the untreated group (p = 0.002). The maximum estimated volume of the lesions were significantly larger in the treated group (treated group mean 8.9 ml, untreated group mean 4.1 ml; p = 0.016), with a trend towards higher maximum measured blood velocities in the treated group (treated mean 64 cm compared with untreated mean 52 cm; p = 0.1). Steroid injections appear to reduce the volume and blood flow of haemangiomas, this suppression persisting for several months (between 5 and 20) before the lesion later displays the cyclic fluctuations in volume and flow seen with untreated lesions. All treated haemangiomas had some residual vascular anomaly, detectable on ultrasonography, at last follow-up--this being despite absence of clinical signs in most cases. Periorbital capillary haemangiomas requiring steroid therapy for risk of amblyopia were significantly commoner in females, were larger lesions and presented at an earlier age

    The objective of this study was to compare the clinical outcomes of the cervical interlaminar epidural steroid injection (CIESI) for unilateral radiculopathy by the midline or paramedian approaches and to determine the prognostic factors of CIESI. We retrospectively analyzed 182 patients who underwent CIESI from January 2009 to December 2012. Inclusion criteria were no previous spinal steroid injection, presence of a cross-sectional image, and presence of follow-up records. Exclusion criteria were patients with bilateral cervical radiculopathy and/or dominant cervical axial pain, combined peripheral neuropathy, and previous cervical spine surgery. Short-term clinical outcomes were evaluated at the first follow-up after CIESI. We compared the clinical outcomes between the midline and paramedian approaches. Possible prognostic factors for the outcome, such as age, gender, duration of radiculopathy, and cause of radiculopathy were also analyzed. Cervical interlaminar epidural steroid injections were effective in 124 of 182 patients (68.1%) at the first follow-up. There was no significant difference in the clinical outcomes of CIESI, between midline (69.6%) and paramedian (63.7%) approaches (p = 0.723). Cause of radiculopathy was the only significant factor affecting the efficacy of CIESI. Patients with disc herniation had significantly better results than patients with neural foraminal stenosis (82.9% vs. 56.0%) (p < 0.001). There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy. The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis.

    Morton's neuroma is a common foot condition affecting health-related quality of life. Though its management frequently includes steroid injections, evidence of cost-effectiveness is sparse. So, we aimed to evaluate whether steroid injection is cost-effective in treating Morton's neuroma compared with anaesthetic injection alone. We undertook incremental cost-effectiveness and cost-utility analyses from the perspective of the National Health Service, alongside a patient-blinded pragmatic randomised trial in hospital-based orthopaedic outpatient clinics in Edinburgh, UK. Of the original randomised sample of 131 participants with Morton's neuroma (including 67 controls), economic analysis focused on 109 (including 55 controls). Both groups received injections guided by ultrasound. We estimated the incremental cost per point improvement in the area under the curve of the Foot Health Thermometer (FHT-AUC) until three months after injection. We also conducted cost-utility analyses using European Quality of life-5 Dimensions-3 Levels (EQ-5D-3L), enhanced by the Foot Health Thermometer (FHT), to estimate utility and thus quality-adjusted life years (QALYs). The unit cost of an ultrasound-guided steroid injection was £149. Over the three months of follow-up, the mean cost of National Health Service resources was £280 for intervention participants and £202 for control participants - a difference of £79 [bootstrapped 95% confidence interval (CI): £18 to £152]. The corresponding estimated incremental cost-effectiveness ratio was £32 per point improvement in the FHT-AUC (bootstrapped 95% CI: £7 to £100). If decision makers value improvement of one point at £100 (the upper limit of this CI), there is 97.5% probability that steroid injection is cost-effective. As EQ-5D-3L seems unresponsive to changes in foot health, we based secondary cost-utility analysis on the FHT-enhanced EQ-5D. This estimated the corresponding incremental cost-effectiveness ratio as £6,400 per

    Chronic lumbar pain syndromes without neurological deficits are generated by a multitude of causes. Functional, morphological and psychosocial factors are discussed. In many cases a diseased intervertebral disc is found on radiological examination but the clinical relevance of these findings is not clear. For this study it was postulated that a diseased disc results in a local inflammatory reaction therefore causing pain and impairing treatability of patients. An epidural injection of steroids can reduce inflammation and therefore improve treatability and ultimately treatment outcome. A double blind randomized prospective trial was carried out. Patients treated in hospital for a chronic lumbar pain syndrome without neurological deficits within a multimodal treatment program were screened for indications for an epidural steroid injection (e.g. diseased lumbar disc and intention to treat). Patients eligible for the study were randomized into two groups. The treatment group received an epidural injection of 80 mg triamcinolone and 8 ml bupivacaine 0.25 %. The control group received only an epidural injection of 8 ml bupivacaine 0.25 %. In both groups pain intensity and treatability showed a statistically significant improvement after the epidural injection. The differences between the control and treatment groups were small and not clinically relevant. A small subgroup might profit from the steroid injection. In addition the treatability was dependent on psychometric values and the long-term outcome from a reduction of muscular skeletal dysfunctions. After the epidural injection the decrease in pain and increase in treatability was statistically significant. The mechanism of the improvement is not clear and should be examined further. The epidural injection of a steroid in this subgroup of patients did not lead to a clinical improvement in the outcome.

    Olecranon bursitis might be a minor problem in the outpatient clinic but relatively be common to occur. However, there are few well-designed studies comparing approaches to treatment. (1) Which treatment (compression bandaging with nonsteroidal antiinflammatory drugs [NSAIDs], aspiration, or aspiration with steroid injections) is associated with the highest likelihood of resolution of nonseptic olecranon bursitis? (2) Which treatment is associated with earliest resolution of symptoms? (3) What factors are associated with treatment failure by 4 weeks? We enrolled 133 patients from two centers; after applying prespecified exclusions (septic bursitis or concomitant inflammatory arthritis, intraarticular elbow pathology, recent aspiration or steroid injection done elsewhere, and refusal to participate), 90 patients were randomly allocated to receive compression bandaging with NSAIDs (C), aspiration (A), or aspiration with steroid injection (AS) groups (30 patients in each). The groups were similar at baseline in terms of age and gender. Seven patients (four from Group A and three from Group AS) were lost to followup. All patients were followed up weekly for 4 weeks, and the same treatment procedure was repeated if the bursitis recurred with any substantial fluid collection. At 4 weeks, the state of resolution and pain visual analog scale (VAS) were evaluated. Failed resolution was defined as presence of persistent olecranon bursal fluid collection at Week 4 after the initiation of the treatment; on the contrary, if bursal fluid collection was clinically reduced or completely disappeared by the end of Week 4, the treatment was considered successful. We compared the proportion of resolution by Week 4 and the median times to resolution among the treatment groups. In addition, we evaluated whether the resolution affected pain VAS and what factors were associated with the resolution. There were no differences in the proportion of patients whose bursitis resolved by Week 4

    Perioperative management of patients on anticoagulant therapy prior to interventional pain procedures creates a challenge when balancing the risk of bleeding against thromboembolic events. We report a case of epidural hematoma formation in the cervical spine following interlaminar epidural steroid injection in an elderly woman with chronic neck and arm pain, who was on clopidogrel therapy. This is the first reported case of hematoma formation immediately following an epidural steroid injection possibly associated with clopidogrel, even though established guidelines on the timing of the discontinuation of clopidogrel prior to the procedure were exceeded. Severe pain appears to be the first symptom of hematoma formation, and therefore immediate diagnostic workup and evacuation of hematoma are essential in preventing neurological damage. It may be advisable to carry out a test specific for clopidogrel such as the P2Y12 to ensure that there is no residual action on platelet aggregation function, particularly in patients who may be slow metabolizers of clopidogrel. Caution is advised prior to administering analgesics with antiplatelet effects such as ketorolac.

    The aim of the study was to determine the efficacy of deep friction massage in the treatment of lateral epicondylitis by comparing outcomes with a control group treated with splinting and therapy and with an experimental group receiving a local steroid injection. A randomized clinical trial was conducted to compare outcomes after recruitment of consecutive patients presenting with lateral epicondylitis. Patients were randomized to receive one of 3 treatments: group 1: splinting and stretching, group 2: a cortisone injection, or group 3: a lidocaine injection with deep friction massage. Pretreatment and posttreatment parameters of visual analog scale (VAS) pain ratings, Disabilities of the Arm, Shoulder and Hand (DASH) scores, and grip strength were measured. Outcomes were measured at early follow-up (6-12 weeks) and at 6-month follow-up. There was a significant improvement in VAS pain score in all treatment groups at early follow-up. DASH score and grip strength improved in the cortisone injection group and the deep friction massage group at early follow-up; these parameters did not improve in the splinting and stretching group. At 6-month follow-up, only patients in the deep friction massage group demonstrated a significant improvement in all outcome measures, including VAS pain score, DASH score, and grip strength. Deep friction massage is an effective treatment for lateral epicondylitis and can be used in patients who have failed other nonoperative treatments, including cortisone injection.

    Treatment for rib fracture pain can be broadly divided into pharmacologic approaches with oral and/or parenteral medication and interventional approaches utilizing neuraxial analgesia or peripheral nerve blocks to provide pain relief. Both approaches attempt to control nociceptive and neuropathic pain secondary to osseous injury and nerve insult, respectively. Success of treatment is ultimately measured by the ability of the selected modality to decrease pain, chest splinting, and to prevent sequelae of injury, such as pneumonia. Typically, opioids and NSAIDs are the drugs of first choice for acute pain because of ease of administration, immediate onset of action, and rapid titration to effect. In contrast, neuropathic pain medications have a slower onset of action and are more difficult to titrate to therapeutic effect. Interventional approaches include interpleural catheters, intercostal nerve blocks, paravertebral nerve blocks, and thoracic and lumbar epidural catheters. Each intervention has its own inherent advantages, disadvantages, and success rates. Rib fracture pain management practice is founded on the thoracic surgical and anesthesiology literature. Articles addressing rib fracture pain are relatively scarce in the pain medicine literature. As life expectancy increases, and as healthcare system modifications are implemented, pain medicine physicians may be consulted to treat increasing number of patients suffering rib fracture pain and may need to resort to novel therapeutic measures because of financial constraints imposed by those changes. Here we present the first published case series of thoracic epidural steroid injections used for management of rib fracture pain. © 2012 The Authors Pain Practice © 2012 World Institute of Pain.

    To compare the therapeutic effects on upper extremity paresthesia of intra-muscular steroid injections into the scalene muscle with those of stretching exercise only. Twenty patients with upper extremity paresthesia who met the criteria were recruited to participate in this single-blind, crossover study. Fourteen of 20 patients were female. The average age was 45.0 ± 10.5 years and duration of symptom was 12.2 ± 8.7 months. Each participant completed one injection and daily exercise program for 2 weeks. After randomization, half of all patients received ultrasound-guided injection of scalene muscles before exercise, while the other was invested for the other patients. After two weeks, there was a significant decrease of the visual analog scale score of treatment effect compared with baseline in both groups (6.90 to 2.85 after injection and 5.65 to 4.05 after stretching exercise, p<0.01). However, injection resulted in greater improvements than stretching exercise (p<0.01). The number of patients with successful treatment, defined as >50% reduction in post-treatment visual analog scale, was 18 of 20 (90.0%) after injection, compared to 5 of 20 (25.0%) after stretching exercise. There were no cases of unintended brachial plexus block after injection. Ultrasound-guided steroid injection or stretching exercise of scalene muscles led to reduced upper extremity paresthesia in patients who present with localized tenderness in the scalene muscle without electrodiagnostic test abnormalities, although injection treatment resulted in more improvements. The results suggest that symptoms relief might result from injection into the muscle alone not related to blockade of the brachial plexus.

    Intralesional corticosteroid (IL-CS) injections have been used to treat a variety of dermatological and nondermatological diseases. Although an important therapeutic tool in dermatology, a number of local side effects, including skin atrophy, have been reported following IL-CS injections. We recently noticed that a subset of patients with steroid-induced atrophy presented with ivory-colored areas under trichoscopy. We performed a retrospective analysis of trichoscopic images and medical records from patients presenting ivory-colored areas associated with atrophic scalp lesions. In this paper, we associate this feature with the presence of steroid deposits in the dermis and report additional trichoscopic features of steroid-induced atrophy on the scalp, such as prominent blood vessels and visualization of hair bulbs.

    Response to lumbar epidural steroid injection in lumbar radicular pain varies. The purpose of this study is to characterize the changes in quantitative sensory testing (QST) phenotypes of subjects and compare the QST characteristics in patients who do respond to treatment of radicular pain with a lumbar epidural steroid injection (ESI). Prospective, observational pilot study. Outpatient pain center. Twenty subjects with a lower extremity (LE) radicular pain who were scheduled to have an ESI were recruited. At the visit prior to and four weeks following an ESI, subjects underwent QST measurements of both the affected LE and the contralateral unaffected UE. Following an ESI, nine subjects reported a greater than 30% reduction in radicular pain and 11 reported a less than 30% reduction in radicular pain. Subjects who had less than 30% pain reduction response (nonresponders) to an ESI had increased pre-injection warm sensation threshold (37.30 °C, SD = 2.51 vs 40.39, SD = 3.36, P = 0.03) and heat pain threshold (47.22 °C, SD = 1.38, vs 48.83 °C, SD = 2.10, P = 0.04). Further, the nonresponders also showed increased pre-injection warm sensation threshold as measured in the difference of warm sensation detection threshold difference in the affected limb and the unaffected arm (2.68 °C, SD = 2.92 vs 5.67 °C, SD = 3.22, P  = 0.045). Other QST parameters were not affected. The results show that the nonresponders to ESIs have increased detection threshold to heat pain and warm sensation, suggesting that a preexisting dysfunction in the C fibers in this group of subjects who can be detected by QST. Such altered QST characteristics may prognosticate the response to ESIs. © 2017 American Academy of Pain Medicine. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com

    Ultratrace analysis of sample components requires excellent analytical performance in terms of limits of quantitation (LOQ). Micro UHPLC coupled to sensitive tandem mass spectrometry provides state of the art solution for such analytical problems. Using on-line SPE with column switching on a micro UHPLC-MS/MS system allowed to decrease LOQ without any complex sample preparation protocol. The presented method is capable of reaching satisfactory low LOQ values for analysis of thirteen different steroid molecules from human plasma without the most commonly used off-line SPE or compound derivatization. Steroids were determined by using two simple sample preparation methods, based on lower and higher plasma steroid concentrations. In the first method, higher analyte concentrations were directly determined after protein precipitation with methanol. The organic phase obtained from the precipitation was diluted with water and directly injected into the LC-MS system. In the second method, low steroid levels were determined by concentrating the organic phase after steroid extraction. In this case, analytes were extracted with ethyl acetate and reconstituted in 90/10 water/acetonitrile following evaporation to dryness. This step provided much lower LOQs, outperforming previously published values. The method has been validated and subsequently applied to clinical laboratory measurement.

    The purpose of this study was to compare the apoptotic responses to systemic, topical, and intrapolyp injection of glucocorticoid with no treatment in nasal polyps. Prospective, randomized controlled study. Tertiary training hospital. The study was performed on 48 patients with nasal polyposis in the Department of Otorhinolaryngology between 2008 and 2009. Patients were assigned to 1 of 4 groups of 12 patients. Group A was treated with oral methylprednisolone 1 mg/kg/d, and the dose was tapered gradually. Group B received 0.3 mL triamcinolone acetonide (40 mg/mL), which was injected into polyp tissue. Group C was treated with topical 55 µg triamcinolone acetonide 2 times daily for 1 month. Group D received no medication. Samples were collected endoscopically after the seventh day for groups A and B, the first month for group C, and the first visit for group D. Apoptotic indexes were determined using the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method. Statistically significant differences in apoptotic index were found between each steroid-medicated group and the control group (P (D-A) = .0001; P (D-B) = .003; P (D-C) = .026) and between groups A and C (P (A-C) = .012). Group B did not differ significantly from either group A or C (P (A-B) = .11; P (B-C) = .75). The apoptotic index in nasal polyps treated with systemic, topical, and intrapolyp injection forms of glucocorticoids was higher than that in the control group. Systemic steroid treatment induced the most apoptosis.

    Several reviews have so far pointed out on the relevant physiological and pharmacological role exerted by neuroactive steroids in the central nervous system. In the present review we summarize observations indicating that synthesis and metabolism of neuroactive steroids also occur in the peripheral nerves. Interestingly, peripheral nervous system is also a target of their action. Indeed, as here reported neuroactive steroids are physiological regulators of peripheral nerve functions and they may also represent interesting therapeutic tools for different types of peripheral neuropathy.

    To analyze the factors associated with the benefits of concurrent administration of intratympanic steroid injection (ITSI) and oral steroids in patients with acute acoustic trauma (AAT) incurred during military training. Retrospective analysis. Nineteen patients eligible under the criteria established concerning treatment for AAT were retrospectively reviewed in this study. ITSI treatments were administered simultaneously alongside oral prednisolone. Patients were categorized into two groups depending on the time elapsed between exposure to the noise and treatment initiation: 1) "Early Treatment initiation," defined as the treatment being initiated between 3 and 7 days; and 2) "Delayed treatment initiation," defined as the treatment being initiated in >7 days. Pure-tone air conduction threshold audiometry, to record the pure-tone average (PTA) at 2, 4, and 8 kHz, was conducted upon each patient's initial visit, and 1 month after starting treatment. The degree of hearing gain (hearing gain [dB] = [initial PTA] - [final PTA]) was calculated and used as the metric for determining the treatment's outcome. The initial PTA and treatment onset were adopted as possible associated factors. The mean ages of each group were 22.00 ± 2.12 years and 22.83 ± 2.64 years, respectively (p = 0.28). The initial PTAs were 46.41 ± 12.73 dB and 47.22 ± 14.74 dB, respectively (p = 1.00).In the multivariable linear regression analysis, the initial PTA and the treatment initiation showed a significant association (R = 0.37). The unstandardized regression coefficient of the initial PTA was 0.37 (p = 0.04). Patients with early treatment initiation showed significant improvement in the degree of hearing gain compared with delayed treatment initiation (unstandardized regression coefficient = 12.63, p = 0.01). We demonstrated the importance of early treatment onset for maximizing the benefits of concurrent administration of ITSI with oral steroids in

    Purpose To determine if short term effects of intravitreal anti-vascular endothelial growth factor or steroid injection are correlated with fluid turbidity, as detected by spectral domain optical coherence tomography (SD-OCT) in diabetic macular edema (DME) patients. Methods A total of 583 medical records were reviewed and 104 cases were enrolled. Sixty eyes received a single intravitreal bevacizumab injection (IVB) on the first attack of DME and 44 eyes received triamcinolone acetonide treatment (IVTA). Intraretinal fluid turbidity in DME patients was estimated with initialintravitreal SD-OCT and analyzed with color histograms from a Photoshop program. Central macular thickness and visual acuity using a logarithm from the minimum angle of resolution chart, were assessed at the initial period and 2 months after injections. Results Visual acuity and central macular thickness improved after injections in both groups. In the IVB group, visual acuity and central macular thickness changed less as the intraretinal fluid became more turbid. In the IVTA group, visual acuity underwent less change while central macular thickness had a greater reduction (r = -0.675, p = 0.001) as the intraretinal fluid was more turbid. Conclusions IVB and IVTA injections were effective in reducing central macular thickness and improving visual acuity in DME patients. Further, fluid turbidity, which was detected by SD-OCT may be one of the indexes that highlight the influence of the steroid-dependent pathogenetic mechanism. PMID:25120338

    Acute low back pain, radiculopathy, and associated disabilities have a prevalence of 2% in the United States, which represents a significant health problem and a major cause of workplace absence. The condition primarily affects 25- to 45-year-old men and women. Epidural steroid injections (ESIs) are commonly administered to relieve this pain and improve mobility without surgery. This case report presents issues related to the treatment of an epidural hematoma in an 87-year-old man receiving long-term anticoagulant therapy. It reviews the risks, benefits, side effects, complications, and contraindications to ESI and the American Society of Regional Anesthesia consensus recommendations for the performance of neuraxial procedures in patients receiving anticoagulant therapy. It is imperative that any provider who performs ESIs know the risks, benefits, complications, and contraindications for this procedure. Practitioners must also be able to recognize and manage or appropriately refer patients having immediate or delayed complications related to the placement of an ESI.

    Transforaminal Epidural steroid injections (TFESI) have been widely adopted to alleviate and control radicular pain in accord with current guidelines. However, sometimes repeated steroid injections have adverse effects, and thus, this prospective randomized trial was undertaken to compare the effectivenesses of pulsed radiofrequency (PRF) administered to a targeted dorsal root ganglion (DRG) and TFESI for the treatment of radicular pain due to disc herniation. Subjects were recruited when first proved unsuccessful (defined as a score of > 4 on a visual analogue scale (VAS; 0-10 mm) and of > 30% according to the Oswestry Disability Index (ODI) or the Neck Disability Index (NDI)). Forty-four patients that met the inclusion criteria were enrolled. The 38 subjects were randomly assigned to receive either PRF (PRF group; n = 19) or additional TFESI (TFESI group; n = 19) and were then followed for 2, 4, 8, and 12 weeks. To evaluate pain intensity were assessed by VAS. ODI and NDI were applied to evaluate functional disability. Mean VAS scores for cervical and lumbar radicular pain were significantly lower 12 weeks after treatment in both study groups. NDI and ODI scores also declined after treatment. However, no statistically significant difference was observed between the PRF and TFESI groups in terms of VAS, ODI, or NDI scores at any time during follow-up. PRF administered to a DRG might be as effective as TFESI in terms of attenuating radicular pain caused by disc herniation, and its use would avoid the adverse effects of steroid.

    Aim To investigate the impact of statin use on response to fluoroscopy-assisted transforaminal anterior epidural steroid injection (TAESI). Methods Patients undergoing TAESI for low back pain were recruited and stratified according to statin use. Pain was evaluated with a visual analogue scale (VAS) before and at 1, 3, and 6 months after TAESI. Health-related quality-of-life was evaluated using the Short Form 36 (SF-36) questionnaire 6 months after TAESI. Results There were no significant differences in VAS scores after TAESI between statin users (n = 40) and statin nonusers (n = 253). The SF-36 subgroup: role limitations due to emotional problems score was significantly lower in statin users than statin nonusers. There were no significant between-group differences in any other SF-36 parameter. Conclusion Statin use had no effect on pain scores after TAESI. PMID:26912508

    We have compared three intra-articular steroid preparations in a double blind study on 30 patients with rheumatoid arthritis and bilateral synovitis of the knees. One knee was injected with 1.0 ml of either prednisolone t-butyl acetate, methyl prednisolone acetate, or triamcinolone hexacetonide, and the patients were followed up for 6 weeks with regular clinical and thermographic assessments. Thermographic improvement was seen with all 3 drugs but was greatest initially and longest lasting with triamcinolone. No significant systemic improvement was seen with any drug after a single injection, though all 3 steroid preparations suppressed endogenous cortisol. PMID:373651

    Lumbar disc herniation and radiculitis are common elements of low back and lower extremity pain. Among minimally invasive treatments, epidural injections are one of the most commonly performed interventions. However, the literature is mixed about their effectiveness in managing low back and lower extremity pain. In general, individual studies and systematic reviews of epidural steroid injections have been hampered by their study design, baseline differences between treatment groups, inadequate sample sizes, highly controlled settings, lack of validated outcome measures, and the inability to confirm the injectate location because fluoroscopy was not used. A randomized, controlled, double blind, active control trial. A private, interventional pain management practice, specialty referral center in the United States. To assess the effectiveness of fluoroscopically directed caudal epidural injections with local anesthetic with or without steroids in managing chronic low back and lower extremity pain in patients with disc herniation and radiculitis. One hundred twenty patients were randomized to two groups: Group I received 10 mL caudal epidural injections of local anesthetic, lidocaine 0.5%; Group II patients received caudal epidural injections of 0.5% lidocaine, 9 mL, mixed with 1 mL of steroid. Multiple outcome measures were utilized. The primary outcome measures were Numeric Rating Scale (NRS) and the Oswestry Disability Index 2.0 (ODI). Secondary outcome measures were employment status and opioid intake. Significant pain relief improvement was defined as 50% or more improvement in NRS and ODI scores. In the successful category, 77% of Group I had significant pain relief of >/= 50% and functional status improvement of >/= 50% reduction in ODI scores; in Group II it was 76%, whereas overall it was 60% and 65% in Groups I and II. Over the two years, Group I had an average number of procedures of 5.5 ± 2.8; Group II was 5.3 ± 2.4. Even though there was no significant

    Transforaminal and interlaminar epidural steroid injections are commonly used interventional pain management procedures in the treatment of radicular low back pain. Even though several studies have shown that transforaminal injections provide enhanced short-term outcomes in patients with radicular and low back pain, they have also been associated with a higher incidence of unintentional intravascular injection and often dire consequences than have interlaminar injections. We compared 2 different approaches, midline and lateral parasagittal, of lumbar interlaminar epidural steroid injection (LESI) in patients with unilateral lumbosacral radiculopathic pain. We also tested the role of concordant pressure paresthesia occurring during LESI as a prognostic factor in determining the efficacy of LESI. Prospective, randomized, blinded study. Pain management center, part of a teaching-community hospital in a major metropolitan US city. After Institutional Review Board approval, 106 patients undergoing LESI for radicular low back pain were randomly assigned to one of 2 groups (53 patients each) based on approach: midline interlaminar (MIL) and lateral parasagittal interlaminar (PIL). Patients were asked to grade any pressure paresthesia as occurring ipsilaterally or contralaterally to their "usual and customary pain," or in a distribution atypical of their daily pain. Other variables such as: the Oswestry Disability Index questionnaire, pain scores at rest and during movement, use of pain medications, etc. were recorded 20 minutes before the procedure, and on days 1, 7, 14, 21, 28, 60, 120, 180 and 365 after the injection. Results of this study showed statistically and clinically significant pain relief in patients undergoing LESI by both the MIL and PIL approaches. Patients receiving LESI using the lateral parasagittal approach had statistically and clinically longer pain relief then patients receiving LESI via a midline approach. They also had slightly better quality of

    In 79 consecutive patients with unicameral bone cysts we compared the results of aspiration and injection of bone marrow with those of aspiration and injection of steroid. All were treated by the same protocol. The only difference was the substance injected into the cysts. The mean radiological follow-up to detect activity in the cyst was 44 months (12 to 108). Of the 79 patients, 14 received a total of 27 injections of bone marrow and 65 a total of 99 injections of steroid. Repeated injections were required in 57% of patients after bone marrow had been used and in 49% after steroid. No complications were noted in either group. In this series no advantage could be shown for the use of autogenous injection of bone marrow compared with injection of steroid in the management of unicameral bone cysts.

    In the present review we summarize observations to date supporting the concept that neuroactive steroids are synthesized in the peripheral nervous system, regulate the physiology of peripheral nerves and exert notable neuroprotective actions. Indeed, neuroactive steroids have been recently proposed as therapies for different types of peripheral neuropathy, like for instance those occurring during aging, chemotherapy, physical injury and diabetes. Moreover, pharmacological tools able to increase the synthesis of neuroactive steroids might represent new interesting therapeutic strategy to be applied in case of peripheral neuropathy.

    Objective: To evaluate the efficacy of systemic glucocorticoid (steroid) combined with high dose inhaled steroid in the treatment of children with acute laryngitis. Methods: A total of 78 children with acute laryngitis were randomly divided into study group( n =40) and control group( n =38) between November 2016 and April 2017. In addition to routine treatment of anti infection and symptomatic treatment, Dexamethasone injection(0.3-0.5 mg/kg, 1-3 d, according to the patient's condition) was provided to each group. In addition to the treatment mentioned above, the study group were assigned to receive 1.0 mg Budesonide suspension for inhalation, oxygen-driven atomizing inhalation, every/30 minutes, 2 times in a row, after that every 12 hours. The improvement of inspiratory dyspnea, hoarseness, barking cough and wheezing of both groups was evaluated at 30 min, 1 h, 2 h, 6 h, 12 h, 24 h and 72 h after treatment.Sigmaplot 11.5 software was used to analyze the data. Results: No significant difference was detected in terms of inspiratory dyspnea, hoarseness, barking cough or stridor score before treatment between the two groups( P >0.05). Compared with those before treatment, symptoms of inspiratory dyspnea, hoarseness, barking cough and stridor score of both groups improved markedly at 12 h and 24 h after treatment( P <0.05). While there was no significant difference regarding inspiratory dyspnea, hoarseness, barking cough or stridor score at each time point after treatment between the two groups( P >0.05). The effective rate was 92.50% and 92.11% in study group and control group, respectively, and no significant difference was noted ( P >0.05). Conclusion: Compared with single systemic glucocorticoid, systemic glucocorticoids combined with inhaled steroid possessed similar efficacy in treating acute laryngitis and relieving laryngeal obstruction of children.

    INTRODUCTION: The potential for systemic effects due to percutaneous absorption of superpotent topical steroids has been a longstanding concern. The Food and Drug Administration currently recommends limiting the use of superpotent topical steroids to 50g per week for 2 or 4 consecutive weeks depending on the formulation, which is mostly based on the exact duration with which phase 3 clinical trials were allowed to be conducted per the FDA. This article reviews all published clinical incidence of adrenal adverse effects in the medical literature, specifically Cushing's syndrome (CS) and pathologic adrenal suppression (PAAS), to try to ascertain a more realistic limit for the safe use of superpotent topical steroids as it pertains to its potential systemic effects.

    METHODS: Literature search was conducted using PubMed. Only cases of CS and PAAS secondary to the use of Class I superpotent topical steroids were included. Pediatric cases and full articles unavailable in English were excluded.

    RESULTS: There were a total of 14 cases of CS and 5 cases of subsequent PAAS found in the current literature.

    DISCUSSION: From our review of these cases, if the amount used per week is within FDA guidelines, it appears that patients needed to use superpotent topical steroids for far greater than 2 or 4 weeks to develop CS or PAAS. CS did not necessarily predict occurrence of PAAS, but in all cases CS appeared to be a prerequisite for developing PAAS. All cases of CS and all but one case of PAAS were reversible. If excessive amount of greater than 50g per week is avoided, it appears that superpotent topical steroids may be safe to use consecutively for months, perhaps even years, without causing systemic effects.

    Ultratrace analysis of sample components requires excellent analytical performance in terms of limits of quantitation (LoQ). Micro UHPLC coupling with sensitive tandem mass spectrometry provides state of the art solutions for such analytical problems. Decreased column volume in micro LC limits the injectable sample volume. However, if analyte concentration is extremely low, it might be necessary to inject high sample volumes. This is particularly critical for strong sample solvents and weakly retained analytes, which are often the case when preparing biological samples (protein precipitation, sample extraction, etc.). In that case, high injection volumes may cause band broadening, peak distortion or even elution in dead volume. In this study, we evaluated possibilities of high volume injection onto microbore RP-LC columns, when sample solvent is diluted. The presented micro RP-LC-MS/MS method was optimized for the analysis of steroid hormones from human plasma after protein precipitation with organic solvents. A proper sample dilution procedure helps to increase the injection volume without compromising peak shapes. Finally, due to increased injection volume, the limit of quantitation can be decreased by a factor of 2-5, depending on the analytes and the experimental conditions. Copyright © 2016 Elsevier B.V.

    The use of systemic steroids in the treatment of psoriasis is not recommended by dermatological textbooks and guidelines because of the risk of disease deterioration after dose reduction or withdrawal. In contrast to these recommendations, a recent analysis using data from a German nationwide healthcare insurance revealed that systemic steroids were the most frequently prescribed drugs for psoriasis by general practitioners, internal medicine physicians and dermatologists. As there is an obvious discrepancy between the use of systemic steroids for psoriasis and the reported adverse effects, a non-systematic literature search starting 1950 until today was performed to address beneficial and adverse effect of systemic steroids in psoriasis. Non-systematic literature search. Regarding the widespread use of systemic steroids in psoriasis and other medical conditions taking the high prevalence of psoriasis of 2-3% at least in Caucasians into consideration, there is a remarkable lack of literature addressing adverse effects such as rebound, pustular or erythrodermic flares or even new occurrence of psoriasis in patients with a negative disease history. A re-evaluation of the treatment of psoriasis and/or psoriatic arthritis with systemic steroids is necessary. © 2012 The Authors.

    Transforaminal epidural steroid injection (TFESI) is a useful treatment modality for pain management. Most complications of TFESI are minor and transient. However, there is a risk of serious complications such as nerve injury, spinal cord infarct, or paraplegia. Some of the risks are related to direct injury to the vessel or intravascular injection of the particulate steroid. We prospectively tested the hypothesis that the intravascular injection rate of the Whitacre needle is lower than that of the Quincke needle during TFESI. This study was a randomized trial of 1376 TFESIs at the S1 level. We collected data of age, gender, height, weight, laterality (right/left), history of lumbosacral spine operation, history of appropriate interval discontinuation of anticoagulation medicines, and underlying disease. During the S1 TFESI, intrasacral bone contact, a blood aspiration test, and real-time fluoroscopy of the intravascular injection using contrast media were investigated. There were no significant differences in the intravascular injection rate with respect to age, gender, height, weight, hypertension, diabetes mellitus, laterality, history of lumbosacral spine operation, or history of appropriate interval discontinuation of anticoagulation medicines. Intravascular injection was significantly associated with a blood aspiration test (P < 0.001), needle tip type (P = 0.002), intrasacral bone contact (P < 0.001), and physicians (some P < 0.05). The use of Quincke needles and intrasacral bone contact increased the rate of intravascular injection. To reduce the risk of intravascular injection, the use of Whitacre needles without intrasacral bone contact may be a safer and more effective approach.

  1. Blood Glucose Levels After Local Musculoskeletal Steroid Injections in Patients With Diabetes Mellitus: A Clinical Review.

    Diabetes mellitus (DM) has become an epidemic in the United States and is associated with increased risk of multiple comorbidities, including painful musculoskeletal conditions. A common treatment for many of these painful musculoskeletal conditions is local soft tissue and intra-articular corticosteroid injection (CSI). These local injections have the potential to cause elevated blood glucose levels (BGLs) and cause complications in patients with DM. Therefore, it was the objective of this investigation to review the currently available evidence that directly addresses the effects of local CSIs used for painful musculoskeletal conditions on BGL in patients with DM. PubMed, Google Scholar, EMBASE, CINAHL, and Cochrane Review databases were searched with a combination of the terms corticosteroid, glucocorticoid, steroid, injection, musculoskeletal, and diabetes. Search limits included the English language. Bibliographic references from these articles were also examined to identify pertinent literature. Clinical review. Level 3. Ten studies that met the inclusion criteria were reviewed. All these studies showed significant but transient increases in postinjection BGL after a single local CSI in patients with DM. There were no adverse reactions or complications reported. Single, local soft tissue and intra-articular musculoskeletal CSIs are most likely safe in patients with well-controlled DM.

We performed a multicenter, randomized, double-blind, comparative-effectiveness study in 81 participants with ON or migraine with occipital nerve tenderness whose aim was to determine which treatment is superior. Forty-two participants were randomized to receive local anesthetic and saline, and three 120 second cycles of PRF per targeted nerve, and 39 were randomized to receive local anesthetic mixed with deposteroid and 3 rounds of sham PRF. Patients, treating physicians, and evaluators were blinded to interventions. The PRF group experienced a greater reduction in the primary outcome measure, average occipital pain at 6 weeks (mean change from baseline -2.743 ± 2.487 vs -1.377 ± 1.970; P < 0.001), than the steroid group, which persisted through the 6-month follow-up. Comparable benefits favoring PRF were obtained for worst occipital pain through 3 months (mean change from baseline -1.925 ± 3.204 vs -0.541 ± 2.644; P = 0.043), and average overall headache pain through 6 weeks (mean change from baseline -2.738 ± 2.753 vs -1.120 ± 2.1; P = 0.037). Adverse events were similar between groups, and few significant differences were noted for nonpain outcomes. We conclude that although PRF can provide greater pain relief for ON and migraine with occipital nerve tenderness than steroid injections, the superior analgesia may not be accompanied by comparable improvement on other outcome measures.

    Using a systematic review, we investigated whether there is an increased risk of post-operative infection in patients who have received an intra-articular corticosteroid injection to the hip for osteoarthritis prior to total hip arthroplasty (THA). Studies dealing with an intra-articular corticosteroid injection to the hip and infection following subsequent THA were identified from databases for the period between 1990 to 2013. Retrieved articles were independently assessed for their methodological quality. A total of nine studies met the inclusion criteria. Two recommended against a steroid injection prior to THA and seven found no risk with an injection. No prospective controlled trials were identified. Most studies were retrospective. Lack of information about the methodology was a consistent flaw. The literature in this area is scarce and the evidence is weak. Most studies were retrospective, and confounding factors were poorly defined or not addressed. There is thus currently insufficient evidence to conclude that an intra-articular corticosteroid injection administered prior to THA increases the rate of infection. High quality, multicentre randomised trials are needed to address this issue. Cite this article: Bone Joint J 2016;98-B:1027-35. ©2016 The British Editorial Society of Bone & Joint Surgery.

  5. Use of postoperative steroids to reduce pain and inflammation.

    Postoperative injection of a steroid is used by many podiatric surgeons to reduce pain and inflammation after foot surgery. The authors present a review of the literature on postoperative steroid use from many medical specialties as well as a review of wound and bone healing. The literature indicates that using a steroid is a safe and effective means to reduce postoperative pain and edema. Studies have shown steroids to delay healing, inhibit collagen synthesis, and increase the risk of postoperative infection. No author reported a delay in wound or bone healing or increased infection rate in patients in which a steroid was used. Although there is literature to support this practice, many questions remain and further investigation is needed.

    Intractable plantar fasciitis can be a difficult condition to treat. Early results of platelet rich plasma (PRP) injection have been promising. We compared PRP to traditional cortisone injection in the treatment of chronic cases of plantar fasciitis resistant to traditional nonoperative management. The aim of the study was to compare the efficacy of PRP to that of Steroid at 3, 6 and 12 months after injection. 60 heels with intractable plantar fasciitis who had failed conservative treatment were randomised to receive either PRP or Steroid injection. All patients were assessed with the Roles-Maudsley (RM) Score, Visual Analogue Score (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) score. Data was collected prospectively on the cohort, pre-treatment, at 3, 6 and 12 months post injection and the results were compared. Pre-injection, the two groups were well matched with no statistically significant difference. At 3 months, all three outcome scores had significantly improved from their pretreatment level in both groups. The scores in the Steroid arm were marginally better than in the PRP arm, but this difference was not statistically significant. At 6 months, there was no statistically significant difference between the two groups, though there was a trend for the PRP scores to become better than the Steroid scores. At 12 months, the RM, VAS and AOFAS scores in the PRP arm (1.9, 3.3 and 88.5) were significantly better than the Steroid arm (2.6, 5.3 and 75) with P values of .013, .028 and .033, respectively. PRP is as effective as Steroid injection at achieving symptom relief at 3 and 6 months after injection, for the treatment of plantar fasciitis, but unlike Steroid, its effect does not wear off with time. At 12 months, PRP is significantly more effective than Steroid, making it better and more durable than cortisone injection. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Purpose. To evaluate the treatment effect and side effect of Shenqi Fuzheng Injection (SFI) on alleviating transient worsening of myasthenia gravis (MG) symptoms caused by high-dose steroids pulse therapy. Methods. Sixty-six consecutive patients with MG were randomly divided into two groups: the treatment group treated with SFI and methylprednisolone pulse therapy (MPT) and the control group treated with MPT alone. The severity of MG before, during, and after MPT and the duration of transient worsening (TW) were evaluated and compared with the clinical absolute scoring (AS) and relative scoring (RS) system. Results. Twenty-nine patients experienced TW in each group. At TW, the AS was significantly increased (P < 0.000) in both groups compared with baseline data, with the AS increase in the treatment group (16.8 ± 2) significantly smaller (P < 0.05) than in the control group (24.9 ± 2.5). At the end of the treatment course, the AS for the treatment group was significantly decreased (7.5 ± 0.9) compared with at TW, although no significant difference compared with the control (9.7 ± 1.1). The TW lasted 1–6 days (mean 3.7) for the treatment group, significantly shorter (P < 0.05) than 2–12 days (mean 7.8) for the control. The RS for the treatment group at the end of treatment was 43.8%–100% (mean 76.8% ± 2.6%), significantly better than the control group: 33.3%–100% (mean 67.2 ± 3.6%). Slight side effects (18.75%) included maldigestion and rash in the treatment group. Conclusion. SFI has a better treatment effect and few side effects and can alleviate the severity and shorten the duration of the transient worsening of MG during steroids pulse therapy. PMID:24348721

    This study describes an on-line stacking CE approach by sweeping with whole capillary sample filling for analyzing five anabolic androgenic steroids in urine samples. The five anabolic steroids for detection were androstenedione, testosterone, epitestosterone, boldenone, and clostebol. Anabolic androgenic steroids are abused in sport doping because they can promote muscle growth. Therefore, a sensitive detection method is imperatively required for monitoring the urine samples of athletes. In this research, an interesting and reliable stacking capillary electrophoresis method was established for analysis of anabolic steroids in urine. After liquid-liquid extraction by n-hexane, the supernatant was dried and reconstituted with 30 mM phosphate buffer (pH 5.00) and loaded into the capillary by hydrodynamic injection (10 psi, 99.9 s). The stacking and separation were simultaneously accomplished at -20 kV in phosphate buffer (30 mM, pH 5.0) containing 100 mM sodium dodecyl sulfate and 40 % methanol. During the method validation, calibration curves were linear (r≥0.990) over a range of 50-1,000 ng/mL for the five analytes. In the evaluation of precision and accuracy for this method, the absolute values of the RSD and the RE in the intra-day (n=3) and inter-day (n=5) analyses were all less than 6.6 %. The limit of detection for the five analytes was 30 ng/mL (S/N=5, sampling 99.9 s at 10 psi). Compared with simple MECK, this stacking method possessed a 108- to 175-fold increase in sensitivity. This simple and sensitive stacking method could be used as a powerful tool for monitoring the illegal use of doping.

    Objective: A cervical epidural steroid injection is one of the most commonly performed interventions to manage chronic neck pain and cervical radiculopathy. Despite its many severe complications, cervical transforaminal epidural steroid injection (CTFESI) is a clinically necessary modality for managing neck pain and cervical radiculopathy. We aimed in this study to find a safer optimal needle entry angle to decrease the chance of an accidental vertebral artery (VA) puncture even with a proper needle entry angle and to visualize the target of the needle tip. Methods: This retrospective study included 312 patients with neck pain or cervical radiculopathy who had undergone magnetic resonance imaging scans for diagnosis and treatment. The first line was drawn from the midpoint of the two articular pillars and passed through the exact midline of the spinous process. The second line was drawn parallel to the ventral lamina line (conventional transforaminal approach line, CTAL). The third line was drawn parallel to the ventral margin at the midpoint of the superior articular process's ventral border (new transforaminal approach line, NTAL). The angle of intersection between the midline and CTAL versus with NTAL were measured from both sides (right and left) at C5-6, C6-7, and C7-T1 levels. Also, the distance of CTAL and NTAL from VA were measured from both sides at each level. We examined whether the CTAL and NTAL would penetrate the ipsilateral VA, internal carotid artery (ICA), and internal jugular vein (IJV). Results: There were significant differences between CTAL and NTAL angles at all levels (P < 0.001). There were significant differences between the distance of CTAL and NTAL from VA at all levels (P < 0.001). There were also significant differences between the observed frequency of CTAL and NTAL that would penetrate the major ipsilateral vessel (VA, ICA, and IJV) on all levels and sides (P < 0.001~0.030). Conclusion: The angle of NTAL (approximately 70°) is safer

    Diabetic macular edema (DME), pseudophakic cystoid macular edema (CME), age-related macular degeneration (AMD), retinal vascular occlusion (RVO), and uveitis are ocular conditions related to severe visual impairment worldwide. Corticosteroids have been widely used in the treatment of these retinal diseases, due to their well-known antiangiogenic, antiedematous, and anti-inflammatory properties. Intravitreal steroids have emerged as novel and essential tools in the ophthalmologist's armamentarium, allowing for maximization of drug efficacy and limited risk of systemic side effects. Recent advances in ocular drug delivery methods led to the development of intraocular implants, which help to provide prolonged treatment with controlled drug release. Moreover, they may add some potential advantages over traditional intraocular injections by delivering certain rates of drug directly to the site of action, amplifying the drug's half-life, contributing in the minimization of peak plasma levels of the drug, and avoiding the side effects associated with repeated intravitreal injections. The purpose of this review is to provide an update on the use of intravitreal steroids as a treatment option for a variety of retinal diseases and to review the current literature considering their properties, safety, and adverse events.

    The efficacy of pharmacological interventions in sciatica is limited and the use of systemic steroids is still controversial. We aimed at evaluating the efficacy and tolerance of systemic steroids in sciatica. A systematic literature search was performed in the Medline, Embase and Cochrane databases until February 2010. Randomized placebo-controlled trials evaluating the efficacy and the tolerance of systemic steroids in sciatica were included. Efficacy and tolerance were assessed using the relative risk (RR) and 95% CI with the inverse variance method (RR > 1 means that the event is more likely to occur in the steroid group). We explored the heterogeneity between the studies using subgroup analysis. Seven studies (383 patients) were included. The difference in the rate of responders between both groups was not statistically significant (RR = 1.22, 95% CI 0.96, 1.56). The rate of adverse events was 13.3% for the patients in the steroid group and 6.6% for the placebo group (RR = 2.01, 95% CI 1.06, 3.80). The number needed to harm was 20 (95% CI 10, ∞). Twenty (15.3%) patients in the steroid group and seven (5.7%) patients in the placebo group underwent surgery. A trend towards a higher requirement for spinal surgery was observed in the steroid group (RR = 1.14, 95% CI 0.74, 1.75). The methodological quality slightly influenced the results. We did not find any publication bias. Steroid efficacy is not superior to the placebo in sciatica, but it has more side effects. The tolerance : efficacy ratio indicates against the use of systemic steroids in sciatica.

    Endolymphatic sac decompression surgery (ELSD) may be used to treat patients who have Menière's 's disease refractory to medical therapy. In this study, we investigated whether or not the injection of steroid into the endolymphatic sac at the time of ELSD provides additional benefit to patient outcomes. Randomized prospective single-blinded placebo-controlled study. Tertiary center. Patients with Menière's disease with poorly controlled vertigo despite medical therapy and serviceable hearing that were offered ELSD. Patients randomized into two groups, with control group (n = 17) undergone ELSD without steroid injection and experimental group undergone ELSD with steroid injection (n = 18) MAIN OUTCOME MEASURE(S):: Audiogram, dizziness handicap inventory, tinnitus handicap inventory, frequency of vertigo spells, functional level scale, and quality of life were obtained at multiple intervals from preoperatively to 24 months postoperatively. ELSD resulted in a statistically significant improvement in vertigo control whether or not steroid was injected into the endolymphatic sac at the time of surgery. However, no additional benefit was observed with the addition of intra-sac steroid injection. No statistical difference in pure-tone average, tinnitus handicap inventory, dizziness handicap inventory, or quality of life was observed between the steroid and nonsteroid surgical groups up to 24 months postoperatively. ELSD is an effective treatment for Menière's disease refractory to medical therapy; however, the addition of intra-sac steroid injection at the time of surgery does not seem to result in a further improvement in patient outcomes.

    This study looks into the efficacy and safety of the transforaminal lumbar epidural steroid injection (TLESI) applied to patients with radiculopathy due to lumbar disk herniation. The patients' files which were applied TLESI, were retrospectively scanned. Patients who did not respond to one-month conservative treatment and who were detected to have bulging or protruding lumbar disk herniation as a result of imaging methods were included in the study. All applications were performed with C-arm fluoroscopy under local anesthesia by outpatient method. In all cases, a mix of 80 mg triamsinolone and 0.25% bupivacaine, was transforaminally injected to the anterior epidural area. Initial VAS pain scores were compared with the values of the 1, 3 and 6th months after the application. Patient satisfaction was determined through scoring. Furthermore, early and late term complications were collected for evaluation. A total of 222 patients were administered TLESI 460 times (average: 2.1, repeat interval: 1-6 times). The applications were carried out most frequently at the levels of L4-L5 and L5-S1. While the initial VAS score average was 8.2±0.7, after TLESI, it was 5.0±1.6, 4.8±1.5 and 5.1±1.5 in the 1, 3 and 6th months, respectively. 63.9% of the patients (n=142) defined the treatment as 'good and excellent'. No major complications were experienced and the overall minor complication rate was 11.1%. It was seen that TLESI was an efficient and safe method in the short and medium term.

    Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) allows for the direct analysis of multiple hormones in a single probe with minimal sample volume. Rodent-based animal studies strongly rely on microsampling, such as the dry blood spot (DBS) method. However, DBS suffers the drawback of hematocrit-dependence (non-volumetric). Hence, novel volumetric microsampling techniques were introduced recently, allowing sampling of fixed accurate volumes. We compared these methods for steroid analysis in the rat to improve inter-system comparability. We analyzed steroid levels in blood using the absorptive microsampling devices Whatman® 903 Protein Saver Cards, Noviplex™ Plasma Prep Cards and the Mitra™ Microsampling device and compared the obtained results to the respective EDTA plasma levels. Quantitative steroid analysis was performed via LC-MS/MS. For the determination of the plasma volume factor for each steroid, their levels in pooled blood samples from each human adults and rats (18weeks) were compared and the transferability of these factors was evaluated in a new set of juvenile (21days) and adult (18weeks) rats. Hematocrit was determined concomitantly. Using these approaches, we were unable to apply one single volume factor for each steroid. Instead, plasma volume factors had to be adjusted for the recovery rate of each steroid and device individually. The tested microsampling systems did not allow the use of one single volume factor for adult and juvenile rats based on an unexpectedly strong hematocrit-dependency and other steroid specific (pre-analytic) factors. Our study provides correction factors for LC-MS/MS steroid analysis of volumetric and non-volumetric microsampling systems in comparison to plasma. It argues for thorough analysis of chromatographic effects before the use of novel volumetric systems for steroid analysis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Frozen shoulder is a painful condition with gradual onset and loss of range of motion in the glenohumeral joint. To investigate the efficacy of ultrasound(US)-guided intra-articular (IA) ketorolac injection with capsular distension compared with steroid injection alone in patients with frozen shoulder by assessing pain relief, functional improvements, and range of motion at 1,3 and 6 months after the last injections. Between January 2009 and December 2012, 121 patient were treated with US-guided IA steroid injection or IA ketorolac injection with capsular distension for frozen shoulder. Patients (n= 57) of US-guided IA steroid injection group were administered with a mixture of 0.5% lidocaine (4 ml) plus triamcinolone (40 mg/ml; 1 ml) and patients (n= 64) of US-guided IA ketorolac injection with capsular distension group were administered by using 0.5% lidocaine (19 mL) plus ketorolac (30 mg/ml; 1 mL) for capsular distension. Outcome measurement was assessed by Shoulder Pain and Disability Index (SPADI), Verbal Numeric pain Scale (VNS) and passive range of motion (ROM) before injections and at 1, 3 and 6 months after the last injections. We regarded the outcomes as a success if patients obtained significant pain relief (as measured by > 50% improvement in the VNS score and 20 point improvement in the SPASI) at 1, 3 and 6 months after the last injections. SPADI, VNS and passive ROM were improved 1, 3 and 6 months after the last injections in both groups. The statistical differences were not observed in SPADI, VNS between groups (p< 0.05). Successful treatment rate were not significantly different between the groups as well as in 1, 3 and 6 month outcomes. However, greater improvement was found in a matter of range of motion in patients receiving IA ketorolac injection with capsular distension than participants receiving US-guided IA steroid injection alone. Significant differences in improvement at 3 and 6 months were observed for shoulder passive abduction and

    OBJECTIVE: To identify unsupervised anabolic steroid regimens used by athletes. METHODS: 100 athletes attending four gymnasia were surveyed using an anonymous self administered questionnaire. RESULTS: Anabolic steroid doses ranged from 250 to 3200 mg per week and users combined different drugs to achieve these doses. Injectable and oral preparations were used in cycles lasting four to 12 weeks. Eighty six per cent of users admitted to the regular use of drugs other than steroids for various reasons, including additional anabolic effects, the minimisation of steroid related side effects, and withdrawal symptoms. Acne, striae, and gynaecomastia were the most commonly reported subjective side effects. CONCLUSIONS: Multiple steroids are combined in megadoses and self administered in a cyclical fashion. Polypharmacy is practised by over 80% of steroid users. Skeletal muscle hypertrophy along with acne, striae, and gynaecomastia are frequent physical signs associated with steroid use.

    To systematically appraise published comparative effectiveness evidence (clinical and economic) of epidural steroid injections (ESI) for lumbar spinal stenosis and to estimate Medicare reimbursement amounts for ESI procedures. TYPE: Systematic review. PubMed, Embase, and CINAHL were searched through August 2012 for key words that pertain to low back pain, spinal stenosis or sciatica, and epidural steroid injection. We used institutional and Medicare reimbursement amounts for our cost estimation. Articles published in English that assessed ESIs for adults with lumbar spinal stenosis versus a comparison intervention were included. Our search identified 146 unique articles, and 138 were excluded due to noncomparative study design, not having a study population with lumbar spinal stenosis, not having an appropriate outcome, or not being in English. We fully summarized 6 randomized controlled trials and 2 large observational studies. Randomized controlled trial articles were reviewed, and the study population, sample size, treatment groups, ESI dosage, ESI approaches, concomitant interventions, outcomes, and follow-up time were reported. Descriptive resource use estimates for ESIs were calculated with use of data from our institution during 2010 and Medicare-based reimbursement amounts. ESIs or anesthetic injections alone resulted in better short-term improvement in walking distance compared with control injections. However, there were no longer-term differences. No differences between ESIs versus anesthetic in self-reported improvement in pain were reported. Transforaminal approaches had better improvement in pain scores (≤4 months) compared with interlaminar injections. Two observational studies indicated increased rates of lumbar ESI in Medicare beneficiaries. Our sample included 279 patients who received at least 1 ESI during 2010, with an estimated mean total outpatient reimbursement for one ESI procedure "event" to be $637, based on 2010 Medicare reimbursement

    Purpose: Patients diagnosed as thoracolumbar junction syndrome were divided into 3 treatment groups and the results of each modality were compared. Materials and Method: 30 Patients were included in the study with the definitive diagnosis of Maigne’s Syndrome. The first group received exercise therapy, the second group was treated with local steroid injections and the third group was the combination therapy group of both injection and exercise. Findings: 30 Patients were divided into 3 groups. Each group had 10 patients. The average age of the groups was detected to be 23.43 ± 3.75. A flattening was detected in 4 patients of the first group (40%), 6 patients of the second group (60%) and 4 patients of the third group (40%) during the lumbar lordosis. While the average difference of the VAS values was (2.80) as the lowest for the injection group before and after treatment at rest, the highest value (3.30) was observed in the combined treatment group. The results shown on the Oswestry scale of the first month difference (16.10), and the third month difference (22.40) were statistically better than the other groups in the combined treatment group. Results: As a result of this study, while in all three treatment groups in the Oswestry scale, VAS scores at rest or at movement during the regular controls before and after the treatment showed statistically significant difference; the best results were obtained in the group administered to the combined injection and exercise therapy.

    This study investigated multidimensional treatment outcomes, including prognostic factors and side effects of vocal fold steroid injection (VFSI). We recruited 126 consecutive patients, including patients with 49 nodules, 47 polyps, and 30 mucus retention cysts. All the patients received VFSI under local anesthesia in the office settings. Treatment outcomes were evaluated 1 and 2 months after the procedure, including endoscopic evaluation, perceptual voice quality (GRB scores), acoustic analysis, and 10-item Voice Handicap Index (VHI-10). More than 80% of the patients reported subjective improvements after VFSI. Objective measurements revealed significant improvements from baseline in most of the outcome parameters (P<0.05). Higher occupational vocal demands and fibrotic vocal nodules were significantly associated with poorer clinical responses as measured by the VHI-10 and GRB scores, respectively. For vocal polyps, dysphonia for more than 12 months were significantly associated with higher postoperative VHI-10 scores, whereas patients with laryngopharyngeal reflux (LPR) showed significantly poor postoperative voice quality as measured by GRB scores. Side effects after VFSI included hematoma (27%), triamcinolone deposits (4%), and vocal atrophy (1%), which resolved spontaneously within 1-2 months. Presentation with vocal fold ectasias/varicosities and higher vocal demands were significantly correlated with postoperative vocal hematoma. This study demonstrated significant improvements after VFSI in vocal nodules, polyps, and cysts. Occupational vocal demand and subtypes of vocal nodules are closely related to the treatment outcomes after VFSI, whereas symptom duration and LPR were significant prognostic factors for VFSI treatment outcomes in vocal polyps. Side effects after receiving VFSI were mostly self-limited without sequel, whereas the incidence rates might be varied by the injection approach and the timing for postoperative follow-up.

    Many hydrological and geochemical studies rely on data resulting from injection of tracers and chemicals into groundwater wells. The even distribution of liquids to multiple injection points can be challenging or expensive, especially when using multiple pumps. An injection system was designed using one chemical metering pump to evenly distribute the desired influent simultaneously to 15 individual injection points through an injection manifold. The system was constructed with only one metal part contacting the fluid due to the low pH of the injection solutions. The injection manifold system was used during a three-month pilot scale injection experiment at the Vineland Chemical Company Superfund site. During the two injection phases of the experiment (Phase I = 0.27 L/min total flow, Phase II = 0.56 L/min total flow), flow measurements were made 20 times over three months; an even distribution of flow to each injection well was maintained (RSD <4%). This durable system is expandable to at least 16 injection points and should be adaptable to other injection experiments that require distribution of air-stable liquids to multiple injection points with a single pump.

    The relationship of pain relief from a recently presented CT-guided indirect cervical nerve root injection with local anesthetics and steroids to surgical decompression as a treatment for single-level cervical radiculopathy is not clear. This retrospective study aimed to compare the immediate and 6-week post-injection effects to the short- and long-term outcomes after surgical decompression, specifically in regard to pain relief. Patients (n = 39, age 47 ± 10 years) who had undergone CT-guided indirect injection with local anesthetics and steroids as an initial treatment for single cervical nerve root radiculopathy and who subsequently needed surgical decompression were included retrospectively. Pain levels (VAS scores) were monitored before, immediately after, and 6 weeks after injection (n = 34), as well as 6 weeks (n = 38) and a mean of 25 months (SD ± 12) after surgical decompression (n = 36). Correlation analysis was performed to find potential associations of pain relief after injection and after surgery to investigate the predictive value of post-injection pain relief. There was no correlation between immediate pain relief after injection (-32 ± 27 %) and 6 weeks later (-7 ± 19 %), (r = -0.023, p = 0.900). There was an association by tendency between immediate pain relief after injection and post-surgical pain relief at 6 weeks (-82 ± 27 %), (r = 0.28, p = 0.08). Pain relief at follow-up remained high at -70 ± 21 % and was correlated with the immediate pain amelioration effect of the injection (r = 0.37, p = 0.032). Five out of seven patients who reported no pain relief from injection had a pain relief from surgery in excess of 50 %. The amount of immediate radiculopathic pain relief after indirect cervical nerve root injection is associated with the amount of pain relief achieved at long-term follow-up after surgical decompression of single-level cervical radiculopathy

    The forebrain circuits involved in singing and audition (the ‘song system’) in songbirds exhibit a remarkable capacity to synthesize and respond to steroid hormones. This review considers how local brain steroid production impacts the development, sexual differentiation, and activity of song system circuitry. The songbird forebrain contains all of the enzymes necessary for the de novo synthesis of steroids - including neuroestrogens - from cholesterol. Steroid production enzymes are found in neuronal cell bodies, but they are also expressed in pre-synaptic terminals in the song system, indicating a novel mode of brain steroid delivery to local circuits. The song system expresses nuclear hormone receptors, consistent with local action of brain-derived steroids. Local steroid production also occurs in brain regions that do not express nuclear hormone receptors, suggesting a non-classical mode-of-action. Recent evidence indicates that local steroid levels can change rapidly within the forebrain, in a manner similar to traditional neuromodulators. Lastly, we consider growing evidence for modulatory interactions between brain-derived steroids and neurotransmitter/neuropeptide networks within the song system. Songbirds have therefore emerged as a rich and powerful model system to explore the neural and neurochemical regulation of social behavior. PMID:19589382

    2015-01-01

    Background: The efficacy of epidural and facet joint injections has been assessed utilizing multiple solutions including saline, local anesthetic, steroids, and others. The responses to these various solutions have been variable and have not been systematically assessed with long-term follow-ups. Methods: Randomized trials utilizing a true active control design were included. The primary outcome measure was pain relief and the secondary outcome measure was functional improvement. The quality of each individual article was assessed by Cochrane review criteria, as well as the criteria developed by the American Society of Interventional Pain Physicians (ASIPP) for assessing interventional techniques. An evidence analysis was conducted based on the qualitative level of evidence (Level I to IV). Results: A total of 31 trials met the inclusion criteria. There was Level I evidence that local anesthetic with steroids was effective in managing chronic spinal pain based on multiple high-quality randomized controlled trials. The evidence also showed that local anesthetic with steroids and local anesthetic alone were equally effective except in disc herniation, where the superiority of local anesthetic with steroids was demonstrated over local anesthetic alone. Conclusion: This systematic review showed equal efficacy for local anesthetic with steroids and local anesthetic alone in multiple spinal conditions except for disc herniation where the superiority of local anesthetic with steroids was seen over local anesthetic alone.

    Ptosis is a rare complication of periocular steroid use. Studies report that local injections of steroids produce ptosis. We describe the first 2 cases of ptosis because of long-term treatment with topical steroid eye drops. Two cases admitted to our hospital because of ptosis of their right eye after long-term treatment with topical steroid eye drops. Both of them had uncontrolled Posner-Schlossman syndrome. Two cases were diagnosed as steroid-related ptosis. Regulatory anti-inflammation therapy was prescribed for case 1, and after inflammation control, phacoemulsification was done for her. Six months after steroid withdrawal, the levator resection of the right eye was performed. Case 2 refused our advice of steroid reduction and ptosis surgery. After surgery, case 1 retained a symmetrical appearance during a 1-year follow-up. In the surgery, we found thin levator muscles and slack levator palpebrae superioris aponeurosis (LPSA) in the affected eye. Postoperative transmission electron microscopy revealed typical signs of apoptosis in levator muscle cells. We suggest topical application of steroids induces levator muscle apoptosis and LPSA weakness, and results in ptosis. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc.

    IA steroid injections (IASIs) have been shown to relieve pain in knee OA and are widely used in clinical practice. There is, however, evidence of some variation in response. Knowledge of predictors of response could aid in the selection of patients for this therapy. The aim of this systematic review was to determine factors associated with response to IASI in knee OA. Medline, Embase, AMED, CINAHL, Web of Science and Cochrane Central Registers for Controlled Trials up to January 2012 were searched with additional hand searches of relevant articles. Studies included were those that involved adults diagnosed with knee OA in whom IASIs were administered and factors that predicted treatment response were investigated. Eleven publications meeting these criteria were reviewed and relevant information extracted. It was not possible to pool the results because of the different predictors studied, variable outcome measures, different criteria for symptom change and missing data. Given the relative paucity of data and small heterogeneously designed studies, it was difficult to identify predictors of response. Data from individual publications, although not consistent across studies, suggest that the presence of effusion, withdrawal of fluid from the knee, severity of disease, absence of synovitis, injection delivery under US guidance and greater symptoms at baseline may all improve the likelihood of response to IASI. Further larger-scale studies using standardized methods are required to characterize predictors of response and should focus on synovitis, effusion, pain and structural severity of disease. Such data would help in better targeting therapy to those most likely to benefit.

    Piriformis syndrome is an uncommon cause of buttock and leg pain. Some treatment options include the injection of piriformis muscle with local anesthetic and steroids. Various techniques for piriformis muscle injection have been described. Ultrasound allows direct visualization and real time injection of the piriformis muscle. We describe 5 consecutive patients, diagnosed of piriformis syndrome with no improvement after pharmacological treatment. Piriformis muscle injection with local anesthetics and steroids was performed using an ultrasound technique based on a standard technique. All 5 patients have improved their pain measured by numeric verbal scale. One patient had a sciatic after injection that improved in 10 days spontaneously. We describe an ultrasound-guided piriformis muscle injection that has the advantages of being effective, simple, and safe.

    Intratympanic (IT) steroids are often used to treat inner ear disorders such as sudden idiopathic sensorineural hearing loss, autoimmune inner ear disease, and Ménière disease. Administration of corticosteroids via IT injection, via application with a pledget to the round window, or via catheter has been used for this purpose. The frequency of adverse events related to the IT injection of steroids is low, with pain, short-lasting vertigo, otitis media, and tympanic perforations being the most common complications. However, the safety of IT steroid therapy has not yet been established in a randomized clinical trial. In this article, we discuss a group of 11 patients with sensorineural hearing loss who underwent myringotomy and tube placement for home-based dexamethasone instillation and subsequently developed the complication of tympanic membrane perforation. It appears that there is a significantly increased incidence of tympanic membrane perforations in this population.

  11. Design of an Escherichia coli system for whole cell mediated steroid synthesis and molecular evolution of steroid hydroxylases.

    The 15beta-hydroxylase (CYP106A2) from Bacillus megaterium, one of the few bacterial steroid hydroxylases, which has been isolated and characterized so far, catalyses the 15beta-hydroxylation of a variety of steroids. The enzyme can be supported in its activity with adrenodoxin (Adx) and adrenodoxin reductase (AdR) from bovine adrenals, supplying this enzyme with the reducing equivalents necessary for steroid hydroxylation activity. This three-component electron transfer chain was implemented in Escherichia coli by coexpression of the corresponding coding sequences from two plasmids, containing different selection markers and compatible origins of replication. The cDNAs of AdR and Adx on the first plasmid were separated by a ribosome binding sequence, with the reductase preceding the ferredoxin. The second plasmid for CYP106A2 expression was constructed with all features necessary for a molecular evolution approach. The transformed bacteria show the inducible ability to efficiently convert 11-deoxycorticosterone (DOC) to 15beta-DOC at an average rate of 1 mM/d in culture volumes of 300 ml. The steroid conversion system was downscaled to the microtiter plate format and a robot set-up was developed for a fluorescence-based conversion assay as well as a CO difference spectroscopy assay, which enables the screening for enzyme variants with higher activity and stability.

    Unicameral bone cysts are benign lesions that usually spontaneously regress with skeletal maturity; however, the high risk of pathologic fractures often justifies treatment that could reinforce a weakened bone cortex. Various treatments have been proposed but there is no consensus regarding the best procedure. We compared the healing rates and failures of two methods of cure based on multiple injections of corticosteroid or a single injection of demineralized bone matrix (DBM) in association with bone marrow concentrate (BMC). We retrospectively reviewed 184 patients who had one of the two treatments for unicameral bone cysts with cortical erosion. Clinical records were reviewed for treatment failures and radiographs for healing in all patients. The minimum followup was 12 months for the Steroids Group (mean, 48 months; range, 12-120 months) and 12 months for the DBM + BMC Group (mean, 20 months; range, 12-28 months). After one treatment we observed a lower healing rate of cysts treated with multiple injections of steroids compared with the healing after the first injection of DBM + BMC (21% versus 58%, respectively). At last followup, 38% healed with steroids and 71% with DBM + BMC. The rate of failure after one steroid injection was higher than after a single injection of BDM + BMC (63% versus 24%, respectively). We observed no difference in fracture rates after treatment between the two groups. A single injection of DBM added with autologous bone marrow concentrate appears to provide a higher healing rate with a lower number of failures compared with a single injection of steroids.

    Severe-to-profound sudden sensorineural hearing loss (SSNHL) has a poor prognosis. We aimed to compare the efficacy of simultaneous and sequential oral and intratympanic steroids for this condition. Fifty patients with severe-to-profound SSNHL (>70 dB HL) were included from 7 centers. The simultaneous group (27 patients) received oral and intratympanic steroid injections for 2 weeks. The sequential group (23 patients) was treated with oral steroids for 2 weeks and intratympanic steroids for the subsequent 2 weeks. Pure-tone averages (PTA) and word discrimination scores (WDS) were compared before treatment and 2 weeks and 1 and 2 months after treatment. Treatment outcomes according to the modified American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria were also analyzed. The improvement in PTA and WDS at the 2-week follow-up was 23 ± 21 dB HL and 20 ± 39% in the simultaneous group and 31 ± 29 dB HL and 37 ± 42% in the sequential group; this was not statistically significant. Complete or partial recovery at the 2-week follow-up was observed in 26% of the simultaneous group and 30% of the sequential group; this was also not significant. The improvement in PTA and WDS at the 2-month follow-up was 40 ± 20 dB HL and 37 ± 35% in the simultaneous group and 41 ± 25 dB HL and 48 ± 41% in the sequential group; this was not statistically significant. Complete or partial recovery at the 2-month follow-up was observed in 33% of the simultaneous group and 35% of the sequential group; this was also not significant. Seven patients in the sequential group did not need intratympanic steroid injections for sufficient improvement after oral steroids alone. Simultaneous oral/intratympanic steroid treatment yielded a recovery similar to that produced by sequential treatment. Because the addition of intratympanic steroids can be decided upon based on the improvement after an oral steroid, the sequential regimen can be recommended to avoid unnecessary

    The predictive value of short-term arm pain relief after 'indirect' cervical epidural steroid injection (ESI) for the 1-month treatment response has been previously demonstrated. It remained to be answered whether the long-term response could be estimated by the early post-interventional pain course as well. Prospective observational study, following a cohort of n = 45 patients for a period of 24 months after 'indirect' ESI for radiculopathy secondary to a single-level cervical disk herniation (CDH). Arm and neck pain on the visual analog scale (VAS), health-related quality of life with the Short Form-12 (SF-12), and functional outcome with the Neck Pain and Disability (NPAD) Scale were assessed. Any additional invasive treatment after a single injection (second injection or surgery) defined treatment outcome as 'non-response'. At 24 months, n = 30 (66.7%) patients were responders and n = 15 (33.3%) were non-responders. Non-responders exited the follow-up at 1 month (n = 10), at 3 months (n = 4), and at 6 months (n = 1). No patients were injected again or operated on between the 6- and 24-month follow-up. Patients with favorable treatment response at 24 months had significantly lower VAS arm pain (p < 0.05) than non-responders at days 6, 8-11, and at the 3-month follow-up. The previously defined cut-off of > 50% short term pain reduction was not a reliable predictor of the 24-month responder status. SF-12 and NPAD scores were better among treatment responders in the long term. Patients who require a second injection or surgery after 'indirect' cervical ESI for a symptomatic CDH do so within the first 6 months. Short-term pain relief cannot reliably predict the long-term outcome.

  1. The longitudinal effectiveness of lateral atlantoaxial intra-articular steroid injection in the treatment of cervicogenic headache.

    2007-03-01

    The most accepted mechanism of cervicogenic headache is referred pain from cervical structures innervated by the upper three cervical spinal nerves. The lateral atlantoaxial joint is not an uncommon cause of cervicogenic headache. In this retrospective study, we examined the effect of lateral atlantoaxial intra-articular steroid injection in managing 32 patients with cervicogenic headache who have a clinical picture suggestive of atlantoaxial joint pain. The data were collected retrospectively by reviewing the patient's medical records and pain questionnaires. A total of 115 patients with cervicogenic headache who were referred to our institute were identified. Of those patients, 32 had a clinical picture suggestive of atlantoaxial joint pain and subsequently underwent a diagnostic/therapeutic intra-articular block. Fifteen of the 32 patients (46.8%) had a postprocedure pain score of 0 (95% CI = 17.5-72.1%). Twenty-six of the 32 patients (81.2%) had a decrease in their postprocedure pain score of 50% or more (95% CI = 62.4-97.6%). The mean preprocedure pain score was 6.8 and postprocedure was 2.2 (Bonferroni-adjusted P < 0.001). At 1 and 3 months, the mean pain scores were 1.9 (P < 0.001) and 3.6 (P < 0.008), respectively. However, at 6 months, the mean pain score was 3.7, and this was not statistically significant (P = 0.208). Lateral atlantoaxial intra-articular corticosteroid injections may provide short-term analgesia for patients with pain originating from the lateral atlantoaxial joint.

    This review highlights early efforts to translate pre-clinical and clinical findings regarding the role of neuroactive steroids in stress adaptation and PTSD into new therapeutics for PTSD. Numerous studies have demonstrated PTSD-related alterations in resting levels or the reactivity of neuroactive steroids and their targets. These studies also have demonstrated substantial variability in the dysfunction of specific neuroactive steroid systems among PTSD subpopulations. These variabilities have been related to the developmental timing of trauma, severity and type of trauma, genetic background, sex, reproductive state, lifestyle influences such as substance use and exercise, and the presence of comorbid conditions such as depression and chronic pain. Nevertheless, large naturalistic studies and a small placebo-controlled interventional study have revealed generally positive effects of glucocorticoid administration in preventing PTSD after trauma, possibly mediated by glucocorticoid receptor-mediated effects on other targets that impact PTSD risk, including other neuroactive steroid systems. In addition, clinical and preclinical studies show that administration of glucocorticoids, 17β-estradiol, and GABAergic neuroactive steroids or agents that enhance their synthesis can facilitate extinction and extinction retention, depending on dose and timing of dose in relation to these complex PTSD-relevant recovery processes. This suggests that clinical trials designed to test neuroactive steroid therapeutics in PTSD may benefit from such considerations; typical continuous dosing regimens may not be optimal. In addition, validated and clinically accessible methods for identifying specific neuroactive steroid system abnormalities at the individual level are needed to optimize both clinical trial design and precision medicine based treatment targeting.

    To quantify the effect of intra-articular steroid injections (IASIs) on temporomandibular joint (TMJ) synovitis in children with juvenile idiopathic arthritis (JIA) using gadolinium-enhanced magnetic resonance imaging (MRI). The present study was a retrospective study of children with JIA who had undergone TMJ IASIs at Boston Children's Hospital. The patients were included if they had undergone contrast-enhanced MRI both before and after IASI and if the pre-IASI MRI had demonstrated synovitis (enhancement ratio [ER] >1.55). Patients with TMJ pathology or pain unrelated to JIA or a history of facial trauma were excluded. The predictor variables were age, gender, JIA subtype, exposure to medications for arthritis, and a family history of autoimmune disease. The primary outcome variable was the ER. Additional outcome variables included patient-reported pain and the maximal incisal opening (MIO). Twenty-nine subjects (83% female) with a total of 50 injected TMJs were included. The average age at JIA diagnosis and at IASI was 6.8 ± 1.7 years and 12.1 ± 1.9 years, respectively. The mean follow-up period was 22.9 ± 4.3 months (range 5 to 48). The ER decreased in all injected joints, with a mean reduction of 1.05 ± 1.01 (P < .001). The post-IASI ER was less than the normal threshold (1.55) in 18% of the injected TMJs. IASI was associated with an elimination of pain in 89% of the subjects (P < .001) and in augmentation of the MIO by 5.8 ± 2.6 mm (P < .001). In children with JIA and TMJ synovitis, TMJ IASI was associated with a reduction in synovial enhancement, decreased pain, and an increased MIO. Only 18% of injected joints, however, experienced complete resolution of synovitis. These results support the use of IASI in the management of the pain and dysfunction associated with TMJ synovitis. Further study is required to determine the efficacy of IASI in limiting inflammation and future joint destruction. Copyright © 2016 American Association of Oral and

    Endocrine disruptors (ED) are chemicals that affect various aspects of the endocrine system, often leading to the inhibition of steroidogenesis. Current chemical safety policies that restrict human exposure to such chemicals describe often time-consuming and costly methods for the evaluation of ED effects. We aimed to develop an effective tool for accurate phenotypic chemical toxicology studies. We developed an in vitro ED evaluation system using gas chromatography/mass spectrometry (GC/MS/MS) methods for metabolomic analysis of multi-marker profiles. Accounting for sample preparation and GC/MS/MS conditions, we established a screening method that allowed the simultaneous analysis of 17 steroids with good reproducibility and a linear calibration curve. Moreover, we applied the developed system to H295R human adrenocortical cells exposed to forskolin and prochloraz in accordance with the Organization for Economic Cooperation and Development (OECD) guidelines and observed dose-dependent variations in steroid profiles. While the OECD guidelines include only testosterone and 17β-estradiol, our system enabled a comprehensive and highly sensitive analysis of steroid profile alteration due to ED exposure. The application of our ED evaluation screen could be economical and provide novel insights into the hazards of ED exposure to the endocrine system.

    OBJECTIVE—To study the effect of accuracy on the clinical outcome of local steroid injections to the shoulder.
METHODS—37 patients with shoulder symptoms of at least two months' duration received local injections of a mixture of triamcinolone and radiographic contrast material using a standardised technique. Radiographs of the joint were taken immediately afterwards. Details of the patients' symptoms (assessed by visual analogue scales) and range of movement at the joint were obtained before and two weeks after the injection. At follow up the patients were also assessed by means of a five point global rating scale of maximum and current benefit.
RESULTS—14 of the 38 procedures (37%) were judged to be accurately placed: four of the 14 attempted subacromial injections (29%) and 10 of the 24 attempted glenohumeral injections (42%). There were significant differences in relation to outcome between the accurately placed and the inaccurately placed groups.
CONCLUSIONS—Accuracy of steroid placement by injection in patients with shoulder symptoms may significantly affect the clinical outcome.

    Headache is a potential complication of epidural injection. We report a patient who developed headache 5 days after a lumbar epidural steroid injection, which was not related to the epidural procedure, but caused by Duloxetine induced hyponatremia. Antidepressant drug induced headache should be considered in the differential diagnosis of post dural puncture headache.

    Juvenile idiopathic arthritis in temporomandibular joints (TMJs) is often treated with intra-articular steroid injections, which can inhibit condylar growth. The purpose of this study was to compare simvastatin (a cholesterol-lowering drug that reduces TMJ inflammation) with the steroid triamcinolone hexacetonide in experimental TMJ arthritis. Joint inflammation was induced by injecting complete Freund's adjuvant (CFA) into the TMJs of 40 growing Sprague Dawley rats; 4 other rats were left untreated. In the same intra-articular injection, one of the following was applied: (1) 0.5 mg of simvastatin in ethanol carrier, (2) ethanol carrier alone, (3) 0.15 mg of triamcinolone hexacetonide, (4) 0.5 mg of simvastatin and 0.15 mg of triamcinolone hexacetonide, or (5) nothing additional to the CFA. The animals were killed 28 days later, and their mandibles were evaluated morphometrically and with microcomputed tomography. The analysis showed that the TMJs subjected to CFA alone had decreased ramus height compared with those with no treatment (P <0.05). Groups that had injections containing the steroid overall had decreases in weight, ramus height, and bone surface density when compared with the CFA-alone group (P <0.0001). Groups that had injections containing simvastatin, however, had overall increases in weight (P <0.0001), ramus height (P <0.0001), condylar width (P <0.05), condylar bone surface density (P <0.05), and bone volume (P <0.0001) compared with the groups receiving the steroid injections, and they were not different from the healthy (no treatment) group. Treatment of experimentally induced arthritis in TMJs with intra-articular simvastatin preserved normal condylar bone growth. Copyright © 2015 American Association of Orthodontists.

    To determine the effectiveness of three different local injection modalities in the treatment of lateral epicondilitis. In a prospective randomized study on lateral epicondilitis, 75 patients were divided into three equal groups A, B and C (n = 25) and were treated using three different method of local injection. The patients in group A were treated with local injection of a steroid (1 mL triamcinolone) combined with local anaesthetic (1 mL lidocaine), those in group B were treated with injection of local anaesthetic (1 mL lidocaine) combined with peppering technique and those in group C with local injection of a steroid (1 mL triamcinolone) combined with local anaesthetic (1 mL lidocaine) and peppering technique. The outcome was defined by measuring the elbow pain during the activity using a 10-cm visual analogue scale (VAS) and satisfaction with the treatment using a scoring system based on the criteria of the Verhaar et al. at 3 weeks and 6 months after the injection and compared with the pre-treatment condition. There were significant (P = 0.006) differences in the successful outcomes between the three groups at 6 months. In group C in which local steroid + peppering injection technique were used; excellent results were obtained in 84% of patients comparing to 36% and 48% for patients in groups A and B, respectively. The successful outcomes were statistically higher in group C comparing to group A (P = 0.002) and group B (P = 0.011). In all groups, there was a significantly lower pain (VAS) at the 3-week and 6-month follow-ups comparing to the pre-treatment condition. VAS measured at 6-month follow-up were significantly lower in group C comparing to other groups (P = 0.002). In the treatment of lateral epicondilitis, combination of corticosteroid injections with peppering is more effective than corticosteroid injections or peppering injections alone and produces better clinical results.

    This career retrospective describes how the initial work on the mechanism of hormone action provided the tools for the study of hirsutism, virilism, and polycystic ovarian disease. After excessive ovarian and or adrenal androgen secretion in polycystic ovarian disease had been established, the question whether the disease was genetic or acquired, methods to manage hirsutism and methods for the induction of ovulation were addressed. Recognizing that steroid gonadotropin feedback was an important regulatory factor, initial studies were done on the secretion of LH and FSH in the ovulatory cycle. This was followed by the study of basic mechanisms of steroid-gonadotropin feedback system, using castration and steroid replacement and the events surrounding the natural onset of puberty. Studies in ovariectomized rats showed that progesterone was a pivotal enhancer of estrogen-induced gonadotropin release, thus accounting for the preovulatory gonadotropin surge. The effects of progesterone were manifested by depletion of the occupied estrogen receptors of the anterior pituitary, release of hypothalamic LHRH, and inhibition of enzymes that degrade LHRH. Progesterone also promoted the synthesis of FSH in the pituitary. The 3α,5α-reduced metabolite of progesterone brought about selective LH release and acted using the GABA(A) receptor system. The 5α-reduced metabolite of progesterone brought about selective FSH release; the ability of progesterone to bring about FSH release was dependent on its 5α-reduction. The GnRH neuron does not have steroid receptors; the steroid effect was shown to be mediated through the excitatory amino acid glutamate, which in turn stimulated nitric oxide. These observations led to the replacement of the long-accepted belief that ovarian steroids acted directly on the GnRH neuron by the novel concept that the steroid feedback effect was exerted at the glutamatergic neuron, which in turn regulated the GnRH neuron.

    Since it is established that human chorionic gonadotropin (hCG) affects testosterone production and release in the human body, the use of this hormone as a performance enhancing drug has been prohibited by the World Anti-Doping Agency. Nowadays, the only validated biomarker of a hCG doping is its direct quantification in urine. However, this specific parameter is subjected to large inter-individual variability and its determination is directly dependent on the reliability of hCG immunoassays used. In order to counteract these weaknesses, new biomarkers need to be evidenced. To address this issue, a pilot clinical study was performed on 10 volunteers submitted to 3 subsequent hCG injections. Blood and urine samples were collected during two weeks in order to follow the physiological effects on related compounds such as the steroid profile or hormones involved in the hypothalamo-pituitary axis. The hCG pharmacokinetic observed in all subjects was, as expected, prone to important inter-individual variations. Using ROC plots, level of testosterone and testosterone on luteinizing hormone ratio in both blood and urine were found to be the most relevant biomarker of a hCG abuse, regardless of inter-individual variations. In conclusion, this study showed the crucial importance of reliable quantification methods to assess low differences in hormonal patterns. In regard to these results and to anti-doping requirements and constraints, blood together with urine matrix should be included in the anti-doping testing program. Together with a longitudinal follow-up approach it could constitute a new strategy to detect a hCG abuse, applicable to further forms of steroid or other forbidden drug manipulation.

    Dual-fuel injection is an effort to reduce the dependency on diesel and gasoline fuel. Generally, there are two approaches to implement the dual-fuel injection in car system. The first approach is changing the whole injector of the car engine, the consequence is excessive high cost. Alternatively, it also can be achieved by manipulating the system's control signal especially the Electronic Control Unit (ECU) signal. Hence, the study focuses to develop a dual injection timing controller system that likely adopted to control injection time and quantity of compressed natural gas (CNG) and diesel fuel. In this system, Raspberry Pi 3 reacts as main controller unit to receive ECU signal, analyze it and then manipulate its duty cycle to be fed into the Electronic Driver Unit (EDU). The manipulation has changed the duty cycle to two pulses instead of single pulse. A particular pulse mainly used to control injection of diesel fuel and another pulse controls injection of Compressed Natural Gas (CNG). The test indicated promising results that the system can be implemented in the car as piggyback system.

    An important potential consequence of the anabolic steroid misuse is hypogonadotropic hypogonadism due to the inhibition of pituitary secretion of gonadotropins. By the symptoms as testicular atrophy, spermatogenic and fertility disturbances or dysfunction in sexual life, the anabolic steroids induced hypogonadism (ASIH) could be differentiated from organic hypogonadotropic hypogonadism only with difficulty unless the misuse is reported by the user. When diagnosed, the crucial step in the therapy is the stop of anabolic use. Convalescence lasts usually several months or even more than one year. First could be seen the retreat of testicular atrophy followed by the rearrangement of spermatogenesis. The users mainly well informed from internet use for amelioration of the symptoms injections of human choriogonadotropin (hCG), selective estrogen receptor modulators (SERM) or aromatase inhibitors.Key words: anabolic steroids - doping - hypogonadotropic hypogonadism - side effects.

Fifteen (54%) had an experience of inadvertent epidural injection, and five of them had two experiences. Injected drugs were ephedrine (6 times), a mixture of neostigmine and atropine (3), thiopental (2), etilefrine (2), vecuronium (1), suxamethonium (1), bicarbonate (1), midazolam (1), lactated Ringer's solution (1), nicardipine (1), and pentazocine (1). The inadvertent injection of thiopental or bicarbonate was noticed by back pain during injection. No treatment was added after the inadvertent injections, except a patient with an epidural steroid injection following thiopental. No neurological complications were found in any patients.

Several days before he started training he had used tablets and intramuscular injections containing the anabolic steroids: dehydro-chloro-methyltestosterone, boldenone and trenbolone. In addition, he had taken clenbuterol tablets, liothyronine tablets and subcutaneous injections of phosphatidylcholine. Laboratory investigations revealed massive rhabdomyolysis. The patient was treated with intravenous fluid replacement and sodium bicarbonate to alkalinize the urine. He recovered quickly and his renal function remained unaffected.

    Natural fluctuations in sex hormones during the ovarian cycle have enormous influences on ongoing psychological status in the female body. We report here studies of the effects of exogenous sex steroids on anxiety levels in female mice, as evaluated in the elevated cross maze test. Female NMRI mice were subjected to bilateral oophorectomy and one week later received s.c. injections of solvent (sesame oil, controls) or estradiol benzoate for 7 days, either alone or with an additional dose of progesterone on day 7. Elevated maze tests performed 6 h later showed that animals given progesterone had the highest levels of anxiety and the highest levels of grooming reactions as compared with the other groups. Immunohistochemical analysis of the distribution of progesterone receptors in different parts of the brain demonstrated significant increases in the numbers of immunopositive cells after injections of estradiol benzoate alone, with further increases after progesterone injections. Thus, the data obtained here suggest that the genomic effects of sex steroids are important, as they appear to be involved in non-sexual forms of behavior, particularly the level of anxiety.

    To evaluate the efficacy of intra-articular hyaluronic acid (IAHA) injection for hemiplegic shoulder pain (HSP) after stroke. Thirty-one patients with HSP and limited range of motion (ROM) without spasticity of upper extremity were recruited. All subjects were randomly allocated to group A (n=15) for three weekly IAHA injection or group B (n=16) for a single intra-articular steroid (IAS) injection. All injections were administered by an expert physician until the 8th week using a posterior ultrasonography-guided approach. Shoulder joint pain was measured using the Wong-Baker Scale (WBS), while passive ROM was measured in the supine position by an expert physician. There were no significant intergroup differences in WBS or ROM at the 8th week. Improvements in forward flexion and external rotation were observed from the 4th week in the IAHA group and the 8th week in the IAS group. Subjects experienced a statistically significant improvement in pain from the 1st week in the IAS and from the 8th week in IAHA group, respectively. IAHA seems to have a less potent ability to reduce movement pain compared to steroid in the early period. However, there was no statistically significant intergroup difference in WBS and ROM improvements at the 8th week. IAHA might be a good alternative to steroid for managing HSP when the use of steroid is limited.

    Background and PurposeIn CT fluoroscopy (CTF)-guided cervical transforaminal epidural steroid injection (TFESI), the majority of radiation dose is contributed by the planning CT scan rather than the CTF procedure itself. We replaced the planning helical CT with a spot CTF and accordingly changed the patient posture during scout and planning scans. The aim of this study was to test whether radiation dose reduction would be achieved by this protocol modification while still maintaining technical performance.MethodsOverall, 338 consecutive procedures before (control group: n = 163) and after (study group: n = 175) instituting the above-mentioned protocol modification were analyzed retrospectively, comparing patient characteristics (age, sex,more » neck diameter, and level injected) and technical performance [technical success rate, dose-length product (DLP), inadvertent contrast flow incidence, number of CTF acquisitions, and procedural time] between the two groups.ResultsAll injections were technically successful at every level from C3–C4 to C7–T1 without serious complications in both groups. The median DLP of the study group (7.92 mGy·cm) was significantly reduced compared to that of the control group (39.05 mGy·cm, P < 0.001). There were no significant differences between the two groups regarding the incidence of inadvertent contrast flow (20.6 vs. 17.2 %, P = 0.426), number of CTF acquisitions (median 5 vs. 4, P = 0.123), and the procedural time (median 6.62 vs. 6.90 min, P = 0.100).ConclusionsWhen conducting CTF-guided cervical TFESIs, a significant radiation dose reduction (median 79.7 % in DLP) can be achieved by modifying scout and planning steps, without compromising the technical performance.« less

    Low-dose local anesthetic is often used in cervical interlaminar epidural steroid injections (CIESI), yet its effect on upper extremity strength has not been studied. The presence of consequent weakness has potential implications for postprocedure safety. This study aimed to determine whether low-dose lidocaine in a C7-T1 CIESI causes objective weakness. Prospective case series. Academic pain center. Adults, cervical radicular pain. Participants underwent CIESI with 1 mL of 1% lidocaine (3 mL total injectate). Elbow flexion (EF), wrist extension (WE), elbow extension (EE), and handgrip strength were measured by dynamometry at baseline, 15 minutes, and 30 minutes postinjection. Changes in strength from baseline and the proportion of participants with a minimum perceptible change in EF, WE, EE, and handgrip strength (≥20%) and 95% confidence intervals (CIs) were calculated. Twenty-seven participants were included. At 15 and 30 minutes postinjection, there was no within-participant difference in EF, WE, EE, and handgrip strength from baseline overall. Nonetheless, five (19%, 95% CI = 4-33) of the participants demonstrated a 20% or greater strength decrease in at least one myotomal distribution. A 20% or greater decrease in strength was present in left EF 4% (95% CI = 0-11%), right EF 7% (95% CI = 0-17%), left WE 4% (95% CI = 0-11%), and right WE 7% (95% CI = 0-17%). The present data suggest that CIESI with an injectate volume of 3 mL that includes 1 mL of 1% lidocaine may result in objective upper extremity weakness that is above the minimum threshold of perception in a subset of patients. © 2017 American Academy of Pain Medicine.

    To assess in weaned lambs the palliative effects of the non-steroidal anti-inflammatory drug, carprofen, following intradermal injection of cetrimide to induce non-surgical mulesing. We allocated 40 weaned lambs (20-22 weeks old) to four groups of 10 animals: (1) control, 2) conventional surgical mules, (3) intradermal treatment and (4) intradermal treatment + carprofen. Non-surgical mulesing was induced by intradermal injection of 4% (w/w) cetrimide + 3% (w/w) polyvinylpyrrolidone in water. In group 4, carprofen (4 mg/kg, SC) was administered 1 h before intradermal treatment. Five weaners, including an animal from each treatment, were run in each pen. Neutrophil to lymphocyte ratio, cortisol, beta-endorphin and haptoglobin levels and rectal temperature were monitored at least daily for the first 7 days after treatment, then weekly until day 28. Body weight was measured weekly and behaviour was measured every 15 min for 12 h on the day of treatment, then on days 1, 2, 4, 6, 12, 21 and 28 following treatment. The intradermal treatment resulted in high fever and elevated blood cortisol by 12 h. Rectal temperatures were significantly elevated until 5 days after treatment, cortisol was elevated until 3 days after treatment, haptoglobin for at least 7 days after treatment and the neutrophil to lymphocyte ratio until 4 days after treatment. Average daily gain was depressed in the week following treatment. Abnormal behaviours (hunched standing, stiff walking, pawing, lateral lying and lying intention) were increased on the day of treatment and for 6 days post treatment. Carprofen reduced the time spent in abnormal behaviours by approximately two-thirds but did not ameliorate the physiological responses to the intradermal treatment. In weaner sheep, carprofen ameliorated the behavioural responses, but was unable to provide relief from the intense and sustained physiological responses to non-surgical mulesing by intradermal injection of cetrimide.

    A new method was developed for the analysis of natural and synthetic androgenic steroids and their selected metabolites in aquatic environmental matrices using direct large-volume injection (LVI) high performance liquid chromatography (HPLC) tandem mass spectrometry (MS/MS). Method accuracy ranged from 88 to 108% for analytes with well-matched internal standards. Precision, quantified by relative standard deviation (RSD), was less than 12%. Detection limits for the method ranged from 1.2 to 360 ng/L. The method was demonstrated on a series of 1-hr composite wastewater influent samples collected over a day with the purpose of assessing temporal profiles of androgen loads in wastewater. Testosterone, androstenedione, boldenone, and nandrolone were detected in the sample series at concentrations up to 290 ng/L and loads up to 535 mg. Boldenone, a synthetic androgen, had a temporal profile that was strongly correlated to testosterone, a natural human androgen, suggesting its source may be endogenous. An analysis of the sample particulate fraction revealed detectable amounts of sorbed testosterone and androstenedione. Androstenedione sorbed to the particulate fraction accounted for an estimated five to seven percent of the total androstenedione mass. PMID:21391574

    Summary of Background Data Lumbar spinal stenosis is a common incidental finding among adults over the age of 60, The use of ESI in these patients is common, although there is little evidence in the literature to demonstrate the long-term benefit of ESI in the treatment of lumbar stenosis. Objective The hypothesis of this study was that patients who received epidural steroid injections (ESI) during initial treatment as part of the Spine Patient Outcomes Research Trial (SPORT) would have improved clinical outcomes and a lower rate of crossover to surgery compared to patients who did not receive ESI. Methods Patients with lumbar spinal stenosis who received epidural steroid injections within the first three months of enrollment in SPORT (ESI) were compared to patients who did not receive epidural injections during the first three months of the study (No ESI). Results There were 69 ESI patients and 207 No-ESI patients. There were no significant differences in demographic factors, baseline clinical outcome scores, or operative details although there was a significant increase in baseline preference for nonsurgical treatment among ESI patients (62% vs. 33%, p <0.001). There was an average 26 minute increase in operative time and an increased length of stay by 0.9 days among the ESI patients who ultimately underwent surgical treatment. Averaged over four years, there was significantly less improvement in SF36 PF among surgically treated ESI patients (ESI 14.8 vs. No-ESI 22.5, p=0.025). In addition, there was also significantly less improvement among the nonsurgically treated patients in SF36 BP (ESI 7.3 vs. No-ESI 16.7, p=0.007) and SF36 PF (ESI 5.5 vs. No-ESI 15.2, p=0.009). Of the patients assigned to surgical treatment, there was a significantly increased crossover to nonsurgical treatment among patients who received an ESI (ESI 33% vs. No ESI 11%, p=0.012). Of the patients assigned to non-operative treatment, there was a significantly increased crossover to surgical

However, the action of these steroids on different body organs structures is still unclear; therefore, the aim of the present study was to investigate the effect of the intramuscular injection of BOL undecylenate on the different organ structures. A total of 10 adult New Zealand rabbits were divided into two main groups, the first group was the control group, which includes animals that were injected intramuscularly with olive oil and the second group included animals that received two intramuscular injections of 5 mg/kg body weight BOL dissected after 6 weeks. Our results showed that intramuscular injection of rabbits with BOL showed hypertrophy in both skeletal and cardiac muscles, disturbances of the hepatocytes radially arranged cords with multifocal hepatocellular vacuolations in the liver, glomerulus mass reduction with multifocal glomerular injury in the kidney, disturbances of the cycle of spermatogenesis in the testes. In conclusion, using BOL, while preparing for a young bodybuilding contest, may cause an alteration in the histological structure of most of the body organs; these findings suggested that especially young people who misuse anablic androgenic steroids should be careful if they want to use such steroids to enhance their strength and endurance. © The Author(s) 2013.

    To investigate the chemical interaction of calcium hydroxide with the corticosteroid triamcinolone acetonide in Ledermix Paste and in Odontopaste, a new steroid/antibiotic paste. Validated methods were developed to analyse the interaction of calcium hydroxide in two forms, Pulpdent Paste and calcium hydroxide powder, with triamcinolone acetonide within Odontopaste and Ledermix Paste. High-performance liquid chromatography (HPLC) was used to analyse the mixed samples of the pastes and calcium hydroxide. The concentration of triamcinolone acetonide within the pastes was determined over 0, 2, 6, 24 and 72-h time-points. All tests with the HPLC involved the testing of the standard with triplicate injections alongside the samples. All samples were tested in duplicate with each injected twice; therefore, four tests were performed for each investigation. Linearity, precision and specificity of the testing procedures and apparatus were validated. Descriptive statistics are provided. In both pastes, there was a marked rapid destruction of the triamcinolone acetonide steroid upon mixing with calcium hydroxide. Odontopaste suffered a lower rate of destruction of the triamcinolone acetonide component than Ledermix Paste, but both pastes showed very similar degrees of steroid destruction after 72 h. When using calcium hydroxide powder with Ledermix Paste, the triamcinolone was destroyed entirely and immediately. The addition of calcium hydroxide to Odontopaste or Ledermix Paste results in the rapid destruction of the steroid. © 2011 International Endodontic Journal.

    A randomized, controlled, double-blind trial. To assess the effectiveness of fluoroscopically directed caudal epidural injections in managing chronic low back and lower extremity pain in patients with disc herniation and radiculitis with local anesthetic with or without steroids. The available literature on the effectiveness of epidural injections in managing chronic low back pain secondary to disc herniation is highly variable. One hundred twenty patients suffering with low back and lower extremity pain with disc herniation and radiculitis were randomized to one of the two groups: group I received caudal epidural injections with an injection of local anesthetic, lidocaine 0.5%, 10 mL; group II patients received caudal epidural injections with 0.5% lidocaine, 9 mL, mixed with 1 mL of steroid. The Numeric Rating Scale (NRS), the Oswestry Disability Index 2.0 (ODI), employment status, and opioid intake were utilized with assessment at 3, 6, and 12 months posttreatment. The percentage of patients with significant pain relief of 50% or greater and/or improvement in functional status with 50% or more reduction in ODI scores was seen in 70% and 67% in group I and 77% and 75% in group II with average procedures per year of 3.8 ± 1.4 in group I and 3.6 + 1.1 in group II. However, the relief with first and second procedures was significantly higher in the steroid group. The number of injections performed was also higher in local anesthetic group even though overall relief was without any significant difference among the groups. There was no difference among the patients receiving steroids. Caudal epidural injection with local anesthetic with or without steroids might be effective in patients with disc herniation or radiculitis. The present evidence illustrates potential superiority of steroids compared with local anesthetic at 1-year follow-up.

  10. Steroidal Saponins

    Sahu, N. P.; Banerjee, S.; Mondal, N. B.; Mandal, D.

    The medicinal activities of plants are generally due to the secondary metabolites (1) which often occur as glycosides of steroids, terpenoids, phenols etc. Saponins are a group of naturally occurring plant glycosides, characterized by their strong foam-forming properties in aqueous solution. The cardiac glycosides also possess this, property but are classified separately because of their specific biological activity. Unlike the cardiac glycosides, saponins generally do not affect the heart. These are classified as steroid or triterpenoid saponins depending on the nature of the aglycone. Steroidal glycosides are naturally occurring sugar conjugates of C27 steroidal compounds. The aglycone of a steroid saponin is usually a spirostanol or a furostanol. The glycone parts of these compounds are mostly oligosaccharides, arranged either in a linear or branched fashion, attached to hydroxyl groups through an acetal linkage (2, 3). Another class of saponins, the basic steroid saponins, contain nitrogen analogues of steroid sapogenins as aglycones.

    Perioperative systemic steroid administration for rapid recovery in total knee and hip arthroplasty (TKA/THA) is an important and controversial topic. We conducted this systematic review and meta-analysis to evaluate the overall benefits and harms of perioperative systemic steroid in patients undergoing TKA and THA. A comprehensive search was performed on PubMed, OVID, and Web of Science databases, and a systematic approach was carried out starting from the PRISMA recommendations. Relevant randomized controlled trials (RCTs) were selected. The risk of bias was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions version. Data were extracted and meta-analyzed or qualitatively synthesized for all the outcomes. Data were extracted from 11 trials involving 774 procedures. Meta-analysis showed that high-dose systemic steroid (dexamethasone > 0.1 mg/kg) rather than low dose is effective to reduce postoperative nausea and vomiting and postoperative acute pain (within 24 h). In addition, systemic steroid is associated within faster functional rehabilitation and greater inflammation control. On the other hand, systemic steroid is associated with a higher level of postoperative serum glucose on the operation day. The complications between groups are similarly low. Our study suggests that by providing lower incidence of postoperative nausea and vomiting and less postoperative acute pain, high-dose systemic steroid plays a critical role in rapid recovery to TKA and THA. The preliminary results also show the superior possibility of systemic steroid in functional rehabilitation and inflammation control. More large, high-quality studies that investigate the safety and dose-response relationship are necessary.

    2008-04-01

    For further optimization of the automotive power train of diesel engines, advanced combustion processes require a highly flexible injection system, provided e.g. by the common rail (CR) injection technique. In the past, the feasibility to implement injection nozzle volumetric flow sensors based on the thermo-resistive measurement principle has been demonstrated up to injection pressures of 135 MPa (1350 bar). To evaluate the transient behaviour of the system-integrated flow sensors as well as an injection amount indicator used as a reference method, hydraulic simulations on the system level are performed for a CR injection system. Experimentally determined injection timings were found to be in good agreement with calculated values, especially for the novel sensing element which is directly implemented into the hydraulic system. For the first time pressure oscillations occurring after termination of the injection pulse, predicted theoretically, could be verified directly in the nozzle. In addition, the injected amount of fuel is monitored with the highest resolution ever reported in the literature.

  18. Selection and use of crystallization inhibitors for matrix-type transdermal drug-delivery systems containing sex steroids.

    PubMed

    Lipp, R

    1998-12-01

    The purpose of this study was to stabilize transdermal drug-delivery systems (TDDS) highly loaded with sex steroids against recrystallization of drugs during storage. To facilitate the selection of potential crystallization inhibitors a drug-excipient interaction test was also established. Analysis of the thermal behaviour of 1:1 steroid-excipient mixtures by differential scanning calorimetry (DSC) revealed that oestradiol and gestodene interact strongly with silicone dioxide and povidones, e.g. povidone K12. The addition of povidone K12 to polyacrylate-based matrix TDDS containing either 3% oestradiol or 2% gestodene resulted in stable systems which did not recrystallize during storage at 25 degrees C for more than 5 years. Significant recrystallization was, on the other hand, observed in non-stabilized reference patches even after 1 to 2 months storage. The DSC screening model proved very effective for selection of inhibitors of the crystallization of sex steroids in matrix TDDS. The crystallization inhibitor approach is a highly versatile stabilization tool for matrix patches containing high concentrations of sex steroids.

    Steroid acne is a folliculitis that can result from systemic or topical administration of steroid, and has been described as showing a similar clinical picture to Pityrosporum folliculitis, but there have been few reports about the incidence of Pityrosporum ovale and the effect of antimycotic drugs in steroid acne and other acneiform eruptions. Our purpose was to describe the association between steroid acne and P. ovale, and to confirm the superior efficacy of oral antifungal drugs over anti-acne drugs in the treatment of steroid acne. The history, clinical features direct microscopy, histopathologic analysis, and therapeutic results of 125 cases with steroid acne or other acneiform eruptions were described and compared. Over 80% of patients with acneiform eruption receiving systemic steroid revealed significant numbers of P. ovale in the lesional follicle. Furthermore, oral antifungal drug (itraconazole) showed significantly better clinical and mycologic effects than any other group of medications used in this study. Steroid acne and other acneiform eruptions showing discrete follicular papules and/or pustules localized to the upper trunk and acneiform facial skin lesions associated with multiple acneiform lesions on the body in the summer period should be suspected as Pityrosporum folliculitis. In addition, oral antifungal drugs recommended for Pityrosporum folliculitis; however, it will require a larger case-control study to confirm the superiority of antifungal therapy over anti-acne treatment.

    A needle-free delivery system may lead to improved satisfaction and compliance, as well as reduced anxiety among patients requiring frequent or ongoing injections. This report describes a first-in-man assessment comparing Portal Instruments' innovative needle-free injection system with subcutaneous injections using a 27G needle. Forty healthy volunteer participants each received a total of four injections of 1.0 mL sterile saline solution, two with a standard subcutaneous injection using a 27G needle, and two using the Portal injection system. Perception of pain was measured using a 100-mm visual analog scale (VAS). Injection site reactions were assessed at 2 min and at 20-30 min after each injection. Follow-up contact was made 24-48 h after the injections. Subject preference regarding injection type was also assessed. VAS pain scores at Portal injection sites met the criteria to be considered non-inferior to the pain reported at 27G needle injection sites (i.e., upper 95% confidence bound less than +5 mm). Based on a mixed effects model, at time 0, accounting for potential confounding variables, the adjusted difference in VAS scores indicated that Portal injections were 6.5 mm lower than the 27G needle injections (95% CI -10.5, -2.5). No clinically important adverse events were noted. Portal injections were preferred by 24 (60%) of the subjects (P = 0.0015). As an early step in the development of this new needle-free delivery system, the current study has shown that a 1.0-mL saline injection can be given with less pain reported than a standard subcutaneous injection using a 27G needle.

    Epidural steroid injections (ESI) are the most commonly performed pain procedures. Despite numerous studies, controversy continues to surround their effectiveness. The purpose of this study is to determine whether a standard, clinical local anesthetic injection can predict outcomes for ESI. In this multicenter study, 103 patients received two ESI 2 weeks apart. Prior to their first injection, subjects rated the pain intensity of a standardized subcutaneous (SQ) injection of lidocaine prior to the full dose. Numerical rating scale pain scores were correlated with leg and back pain relief, and functional improvement, through 3-month follow-up. A composite successful outcome was predetermined to be a ≥2-point decrease in leg pain score, coupled with a positive global perceived effect. A small but significant relationship was found between SQ pain score and reduction in leg (r = -0.21, 95% CI -0.38 to -0.04; P = 0.03) and back pain (r = -0.22, 95% CI -0.36 to -0.07; P = 0.03). Subjects with a positive outcome at 1 month had a mean SQ pain score of 2.5 (SD 1.9) vs 4.1 (SD 2.7) in those with a negative outcome (P = 0.04). Subjects with SQ pain scores <4/10 had lower leg and back pain scores than those with pain scores ≥4 at 1-month (mean 3.2, SD 2.6 vs 5.1, SD 2.7 for leg, P < 0.01; mean 3.7, SD 2.6 vs 5.0, SD 3.0 for back, P = 0.02) and 3-month (mean 3.8, SD 2.7 vs 5.2, SD 3.1 for leg, P = 0.01; mean 4.0, SD 2.6 vs 4.9, SD 3.1 for back; P = 0.14) follow-up. The results of this study found a weak positive correlation between SQ pain scores and treatment results. Further research should consider whether pain perception in conjunction with other variables might prove to be a reliable predictor for ESI and other procedural outcomes. Wiley Periodicals, Inc.

  2. Ultrasound guided therapeutic injections of the cervical spine and brachial plexus.

    PubMed

    2014-02-01

    Introduction : Recent applications in ultrasound imaging include ultrasound assessment and ultrasound guided therapeutic injections of the spine and brachial plexus. Discussion : Ultrasound is an ideal modality for these regions as it allows accurate safe and quick injection of single or multiple sites. It has the added advantages of lack of ionising radiation, and can be done without requiring large expensive radiology equipment. Conclusion : Brachial plexus pathology may be present in patients presenting for shoulder symptoms where very little is found at imaging the shoulder. It is important to understand the anatomy and normal variants that may exist to be able to recognise when pathology is present. When pathology is demonstrated it is easy to do a trial of therapy with ultrasound guided injection of steroid around the nerve lesion. This review will outline the normal anatomy and variants and common pathology, which can be amenable to ultrasound guided injection of steroid.

  3. Effective prescribing in steroid allergy: controversies and cross-reactions.

    Contact allergy to topical corticosteroids should be considered in all patients who do not respond to, or are made worse by, the use of topical steroids. The incidence of steroid allergy in such patients is reported as 9% to 22% in adult patients and in 25% of children. It can often go undiagnosed for a long time in patients with a long history of dermatologic conditions and steroid use. Although rare, both immediate and delayed-type hypersensitivity reactions have been reported to systemic corticosteroids with an incidence of 0.3%. Reported reactions range from localized eczematous eruptions to systemic reactions, anaphylaxis, and even death. Delayed type reactions to systemically administered steroids may present as a generalized dermatitis, an exanthematous eruption, or occasionally, with blistering or purpura. In this contribution, we clarify the issues surrounding the pathogenesis of steroid allergy, cover the importance of cross-reactions, and describe strategies for the investigation and management for patients with suspected steroid allergy.

    Ethanol and the steroid 3{alpha}-hydroxy-5{alpha}-pregnan-20-one (3{alpha}) are each potent general anesthetics that bring about the rapid loss of the righting response (LRR) in mice. Ethanol is known to enhance the actions of a range of sedative and anesthetic agents. However the effects of ethanol on steroid anesthesia have not previously been described. When ethanol was co-injected with 3{alpha} as compared to 3{alpha} injected alone, the percentage of mice that lost the righting response was substantially increased; the time to LRR was shortened; and 3{alpha} brain levels were increased. The interactions between the two agents were analyzed with the aid ofmore » an isobologram and they were found to be consistent with a hypothesis of additivity. The authors speculate that the role of ethanol as an enhancer of administered 3{alpha} activity described here may extend to the enhancement of endogenous 3{alpha} activity.« less

    1984-01-01

    Patients receiving steroids or having disease processes which increase natural steroid production often demonstrate ''the classic x-ray changes'' of avascular necrosis of bone. Bone scintigraphy in these patients most frequently demonstrates an increased radionuclide localization. The literature suggests that the increased activity is related to healing of the avascular process. In a recent study of Legg-Calve-Perthes Disease (LCPD), 37 of the children had multiple studies and increased activity within the epiphysis during revascularization was extremely rare. Not only are the scintigraphic findings in steroid osteopathy dissimilar to that in healing LCPD, but the time interval for healing is much tomore » short for that of a vascular necrosis and no patients demonstrated an avascular phase on bone scintigraphy. Of 15 children with renal transplants on steroid therapy, 9 demonstrated x-ray and clinical findings of osteopathy. In 8 of 9 instances, bone scintigraphy showed increased localization of radionuclide in the affected bone. Improvement or a return to normal occurred in those patients in whom steroids were discontinued. The following is a proposed mechanism for steroid osteopathy. Steroids affect the osteoblastic and osteoclastic activity of bone and weaken its internal structure. Ordinary stress produces microtrabecular fractures. Fractures characteristically stimulate reactive hyperemia and increase bone metabolism. The result is increased bone radiopharmaceutical localization. The importance of recognizing this concept is that steroid osteopathy is preventable by reducing the administered steroid dose. As opposed to avascular necrosis, bone changes are reversible.« less

    Recent studies have provided evidence that 15α-hydroxytestosterone (15α-T) and 15α-hydroxyprogesterone (15α-P) are produced in vitro and in vivo in adult male sea lampreys (Petromyzonmarinus), and that circulatory levels increase in response to injections with gonadotropin-releasing hormone (GnRH). We examined four species from the Petromyzontidae family including silver lampreys (Ichthyomyzon unicuspis), chestnut lampreys (I. castaneus), American brook lampreys (Lethenteron appendix), and Pacific lampreys (Entosphenus tridentatus) to determine if these unusual steroids were unique to sea lampreys or a common feature in lamprey species. In vitro production was examined through incubations of testis with tritiated precursors, and 15α-T and 15α-P production was confirmed in all species through co-elution with standards on both high performance liquid chromatography (HPLC) and thin layerchromatography. In vivo production was proven by demonstrating that HPLC-fractionated plasma had peaks of immunoreactive 15α-T and 15α-P that co-eluted with standards through using previously developed radioimmunoassays for 15α-T and 15α-P. The possible functionality of 15α-T and 15α-P was further examined in silver and Pacific lampreys by investigating the effect of injection of either type of lamprey GnRH on plasma concentrations of 15α-T and 15α-P. Injections with exogenous GnRH did not affect circulatory levels of either steroid in silver lampreys, and only GnRH III elicited higher levels of both steroids in Pacific lampreys. The 15α-hydroxylase enzyme(s) for steroids appeared to present in adult males of all species examined, but the question of whether 15α-hydroxylated steroids are functional in these lamprey species, and the significance of the 15-hydroxyl group, requires further research.

    To evaluate the effect of the topical steroid, fluorometholone, and the non-steroidal anti-inflammatory drugs (NSAIDs), nepafenac and ketorolac, on inflammatory cytokine expression of the ocular surface in the botulium toxin B-induced murine dry eye model. Topical artificial tears (0.5% carboxymethylcellulose sodium), 0.1% fluorometholone, 0.1% nepafenac, and 0.4% ketorolac were applied 3 times per day in a dry eye mouse model 1 week after intralacrimal botulium toxin B (BTX-B) or saline (sham) injection. Tear production and corneal fluorescein staining were evaluated in all groups before injection at baseline and at 3 time points up to 4 weeks after injection. The pro-inflammatory cytokines interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were evaluated by immunohistochemistry. BTX-B-injected mice showed significantly decreased aqueous tear production and increased corneal fluorescein staining at the 1 and 2 week time points compared with normal control and saline-injected mice. In the BTX-B-injected mice, immunofluorescent staining for TNF-α and IL-1β in corneal and conjunctival epithelial cells increased significantly at the 2 and 4 week time points compared to that of normal and saline-injected mice, and returned to normal levels at the 4 week time point. Topical fluorometholone significantly improved corneal surface staining in the BTX-B-injected mice after 1 week of treatment, and increased the tear production within 2 weeks, but without statistical significant difference. Topical fluorometholone significantly decreased the staining of TNF-α and IL-1β in corneal and conjunctival epithelia after 1-week treatment. Topical artificial tears, 0.1% nepafenac, and 0.4% ketorolac did not show obvious effects on tear production, corneal surface staining, and levels of IL-1β and TNF-α expression in normal, and BTX-B-injected dry eye mice. Topical fluorometholone caused suppression of inflammatory cytokine expression on the ocular surface in the

    Acupuncture with combined manual and low-frequency electrical stimulation, or electroacupuncture (EA), reduces endocrine and reproductive dysfunction in women with polycystic ovary syndrome (PCOS), likely by modulating sympathetic nerve activity or sex steroid synthesis. To test this hypothesis, we induced PCOS in rats by prepubertal implantation of continuous-release letrozole pellets (200 µg/day) or vehicle. Six weeks later, rats were treated for 5-6 weeks with low-frequency EA 5 days/week, subcutaneous injection of 17β-estradiol (2.0 µg) every fourth day, or a β-adrenergic blocker (propranolol hydrochloride, 0.1 mg/kg) 5 days/week. Letrozole controls were handled without needle insertion or injected with sesame oil every fourth day. Estrous cyclicity, ovarian morphology, sex steroids, gonadotropins, insulin-like growth factor I, bone mineral density, and gene and protein expression in ovarian tissue were measured. Low-frequency EA induced estrous-cycle changes, decreased high levels of circulating luteinizing hormone (LH) and the LH/follicle-stimulating hormone (FSH) ratio, decreased high ovarian gene expression of adiponectin receptor 2, and increased expression of adiponectin receptor 2 protein and phosphorylation of ERK1/2. EA also increased cortical bone mineral density. Propranolol decreased ovarian expression of Foxo3, Srd5a1, and Hif1a. Estradiol decreased circulating LH, induced estrous cycle changes, and decreased ovarian expression of Adipor1, Foxo3, and Pik3r1. Further, total bone mineral density was higher in the letrozole-estradiol group. Thus, EA modulates the circulating gonadotropin levels independently of sex steroids or β-adrenergic action and affects the expression of ovarian adiponectin system.

    Abstract Drop attack (DA) associated with Ménière's disease (MD) and delayed endolymphatic hydrops (DEH) is not common and may cause life-threatening clinical problems. The intratympanic dexamethasone (ITD) is one of primary treatments for MD or DEH. Our study investigated the effect of ITD on the DA associated with endolymphatic hydrops (EH). We retrospectively reviewed 10 patients with MD- and DEH-associated DA between January 2009 and December 2013 in Outpatient Department of Otolaryngology, Union Hospital, Wuhan, China. Among them, 7 patients (5 cases with MD, 2 cases of DEH) received ITD (4 times, on weekly basis). Further repeated ITD courses or intratympanic gentamicin (ITG) were given if the vertigo was not satisfactorily controlled. The number of DA and status of vertigo control after intratympanic injection were evaluated. After a follow-up study lasting from 19 to 35 months, DA in 5 cases (71.4%) disappeared after initial ITD course. In 2 cases, DA was altogether controlled after an additional intratympanic injection (repeated ITD or/and ITG). This study showed that ITD promises to be a first-line conservative treatment for MD- or DEH-related DA since the steroid possesses no inner-ear toxicity. Furthermore, for MD- or DEH-related DA refractory to ITD, ITG can be an effective alternative. PMID:28033296

    Since the introduction of intra-articular steroid therapy 40 yr ago there have been many changes in the treatment of rheumatoid patients. Previous studies suggest differing times of response for the same agents. This study reports the response, measured by a five-point pain chart, of 300 patients with painful rheumatoid knees. Sixty received hydrocortisone succinate (HC), 150 received triamcinolone acetonide (TA), and 120 triamcinolone hexacetonide (TH). Results demonstrated little effect with HC, but good responses with TA and TH. More patients were rendered painfree for a longer time with TH; 18% at 12 weeks, as against 9% with TA (chi 2 test P < 0.005). At 12 weeks 59% showed continued improvement with TH as against 44% with TA (chi 2 test P < 0.05). TH is the preferred preparation for injection of the rheumatoid knee.

    The inflow, transformation, and attenuation of natural steroid hormones, phytoestrogens, and estrogenic activity was assessed across the lagoon/sprayfield system of a prototypical commercial swine sow operation. Free and conjugated steroid hormones (estrogens, androgens, and progesterone) were detected in urine and feces of sows across reproductive stages, with progesterone being the most abundant steroid hormone. Excreta also contained phytoestrogens indicative of a soy-based diet; particularly daidzein, genistein, and equol. During storage in barn pits and the anaerobic lagoon, conjugated hormones dissipated, and androgens and progesterone were attenuated. Estrone and equol persisted along the waste disposal route. Following application of lagoon slurry to agricultural soils, all analytes exhibited attenuation within 2 days. However, analytes including estrone, androstenedione, progesterone, and equol remained detectable in soil at two months post-application. Estrogenic activity in the yeast estrogen screen and T47D-KBluc in vitro bioassays generally tracked well with analyte concentrations. Estrone found to be the greatest contributor to estrogenic activity across all sample types. This investigation encompasses the most comprehensive suite of natural hormone and phytoestrogen analytes examined to date across a lagoon/sprayfield system, and provides global insight into the fate of these analytes in this widely used waste management system.

    This study intends to validate the effectiveness of vocal fold steroid injection (VFSI) for mucus retention cysts (MRCs) by comparing the treatment outcome with a control group and investigate the risk factors for recurrence. This study recruited 57 patients with vocal fold MRCs treated with in-office VFSI between January 2014 and December 2016. Another 24 patients with MRCs receiving only conservative treatment during the same study period were included as the control group. Treatment outcomes comparison of the 22 age- and sex- matched patients between the VFSI and control groups demonstrated significantly better improvements among the patients receiving VFSI in maximal phonation, perceptual voice quality, and 10-item voice handicap index. Among the 48 patients exhibited significant lesion resolution after VFSI for MRCs, follow up of a median interval of 18 months showed 16 patients with recurring lesions, ranging from 3 to 43 months. Patients with active alcohol consumption were associated with a higher risk for recurrence. When microsurgery for MRCs is not feasible, VFSI might offer temporary symptom relief. Nevertheless, patients should be informed that the duration of VFSI varies, recurrence is common, and microsurgery remain the gold standard. This article is protected by copyright.

    Membrane receptors are often modulated by steroids and it is necessary to distinguish the effects of steroids at these receptors from effects occurring at nuclear receptors. Additionally, it may also be mechanistically important to distinguish between direct effects caused by binding of steroids to membrane receptors and indirect effects on membrane receptor function caused by steroid perturbation of the membrane containing the receptor. In this regard, ent-steroids, the mirror images of naturally occurring steroids, are novel tools for distinguishing between these various actions of steroids. The review provides a background for understanding the different actions that can be expected of steroids and ent-steroids in biological systems, references for the preparation of ent-steroids, a short discussion about relevant forms of stereoisomerism and the requirements that need to be fulfilled for the interaction between two molecules to be enantioselective. The review then summarizes results of biophysical, biochemical and pharmacological studies published since 1992 in which ent-steroids have been used to investigate the actions of steroids in membranes and/or receptor-mediated signaling pathways.

    Injectable fillers have become a prevalent means of facial rejuvenation and volume expansion. While typically well tolerated, serious complications have been reported. The authors present a case in which an otherwise healthy female with a history of multiple filler injections including poly-L-lactic acid, developed 3 weeks of neuropathic pain in the left temporal fossa following injection. To the best of the authors knowledge, neuropathic pain has not been reported as a complication following poly-L-lactic acid injection. The patient was treated with an injection of steroid and long-acting anesthetic with resolution of symptoms.

    Sex steroids are thought to play a critical developmental role in shaping both cortical and subcortical structures in the human brain. Periods of profound changes in sex steroids invariably coincide with the onset of sex differences in mental health vulnerability, highlighting the importance of sex steroids in determining sexual differentiation of the brain. Yet, most of the evidence for the central effects of sex steroids relies on non-human studies, as several challenges have limited our understanding of these effects in humans: the lack of systematic assessment of the human sex steroid metabolome, the different developmental trajectories of specific sex steroids, the impact of genetic variation and epigenetic changes, and the plethora of interactions between sex steroids, sex chromosomes, neurotransmitters, and other hormonal systems. Here we review how multimodal strategies may be employed to bridge the gap between the basic and clinical understanding of sex steroid-related changes in the human brain.

  17. Cyclodextrins sequester neuroactive steroids and differentiate mechanisms that rate limit steroid actions

    Background and purpose: Neuroactive steroids are potent modulators of GABAA receptors and are thus of interest for their sedative, anxiolytic, anticonvulsant and anaesthetic properties. Cyclodextrins may be useful tools to manipulate neuroactive effects of steroids on GABAA receptors because cyclodextrins form inclusion complexes with at least some steroids that are active at the GABAA receptor, such as (3α,5α)-3-hydroxypregnan-20-one (3α5αP, allopregnanolone). Experimental approach: To assess the versatility of cyclodextrins as steroid modulators, we investigated interactions between γ-cyclodextrin and neuroactive steroids of different structural classes. Key results: Both a bioassay based on electrophysiological assessment of GABAA receptor function and optical measurements of cellular accumulation of a fluorescent steroid analogue suggest that γ-cyclodextrin sequesters steroids rather than directly influencing GABAA receptor function. Neither a 5β-reduced A/B ring fusion nor a sulphate group at carbon 3 affected the presumed inclusion complex formation between steroid and γ-cyclodextrin. Apparent dissociation constants for interactions between natural steroids and γ-cyclodexrin ranged from 10-60 μM. Although γ-cyclodextrin accommodates a range of natural and synthetic steroids, C11 substitutions reduced inclusion complex formation. Using γ-cyclodextrin to remove steroid not directly bound to GABAA receptors, we found that cellular retention of receptor-unbound steroid rate limits potentiation by 3α- hydroxysteroids but not inhibition by sulphated steroids. Conclusions and implications: We conclude that γ-cyclodextrins can be useful, albeit non-specific, tools for terminating the actions of multiple classes of naturally occurring neuroactive steroids.

    To describe whether negative affect and sleep impairment are associated with the clinical effect of epidural steroid injections (ESIs) for low back pain. Observational study; patients were evaluated before ESI and 1 and 3 months after ESI. Spine center and related treatment sites. Participants (N=158) seeking treatment for low back pain with or without radiculopathy. ESI for low back pain with or without radiculopathy. We assessed the dependent (global pain severity for back and leg pain, pain behavior, pain interference) and independent variables (depression, sleep disturbance, and covariates of back pain response) with the Patient-Reported Outcome Measurement Information System (PROMIS) and legacy measures. Outcome was assessed cross-sectionally using multiple regression and longitudinally with path analysis. After 1 month, sleep disturbance was the only predictor for the global ratings of improvement in back pain (R(2)=16.8%) and leg pain (R(2)=11.4%). The proportions of variance explained by sleep disturbance and negative affect for all dependent variables were greater at 3 months than 1 month. Mediation analysis was significant for negative affect for the 3-month outcomes on PROMIS pain behavior (β=.87, P<.01) and pain interference (β=.37, P<.01). There was no evidence of mediation by sleep disturbance for any outcome. Negative affect and sleep disturbance are associated with worse outcomes after ESI. Further research is needed to determine if treatment of negative affect and sleep disturbance prior to or concurrently with ESI will improve outcomes.

    To assess the effectiveness of IA corticosteroid (IAS) injections in PsA and to determine the association between macrophage migration inhibition factor (MIF) gene polymorphism and response to IAS injections. A cohort analysis of PsA patients who were followed prospectively was performed. Clinical response was defined as no tenderness or effusion in the injected joint at 3 months. Relapse was defined as re-occurrence of joint pain or effusion. MIF 173C > G genotyping (rs755622) was performed. Two hundred and twenty patients with 245 IAS injections were included in the study. The probability of responding at 3 months was 41.6%. Within 12 months, 25.5% of the joints relapsed. Clinical factors that were associated with response included duration of psoriasis [Odds ratio (OR) 1.03] and the use of MTX or anti-TNF agents at the time of injection (OR 2.68). Factors that were associated with relapse included injection into large joints (OR 4.58) and elevated sedimentation rate (OR 15.0), whereas absence of clinical and/or radiographic damage (OR 0.23) and duration of PsA (OR 0.92) reduced risk of relapse. MIF polymorphism was not associated with clinical response, but was associated with relapse (OR 3.2). On multivariate analysis including clinical covariates, the association between MIF polymorphism and relapse was lost. IAS injections are effective in PsA. MIF gene polymorphism is associated with relapse. However, this effect is explained by clinical variables that reflect disease activity, suggesting that MIF gene polymorphism influences inflammatory activity.

    The purpose of this review was to identify the relative impact of injected material, location of injury, time to debridement, injection pressure, infection, and the use of adjuvant steroid medication upon the need for amputation after high-pressure injection injuries to the upper extremity. A Medline literature search extending from 1966 to December 2003 was performed, referencing the key words "high-pressure injection injury," "grease gun injury," "paint gun injury," "pressure gun injury," and "high-pressure injection." The results were limited to the English language and to reports involving human subjects. Each abstract was reviewed to confirm that the described injury had occurred in the upper extremity and that it had truly been a high-pressure injection. The reference pages from each of the papers were reviewed to identify additional reports of high-pressure injection injury. Manuscripts describing injuries resulting from hand held syringes or other low-pressure mechanisms were excluded. All of the manuscripts were analyzed to identify the clinical outcome, age, hand dominance, site of injection, substance injected, injection pressure, elapsed time to wide debridement, use of steroids, and incidence of infection. These variables were subjected to a Pearson chi test to determine their impact upon the need for amputation. Four hundred thirty-five cases of high-pressure injection injury to the upper extremity were identified. The amputation rate after these injuries was 30%. The location of the injury and the material injected contributed significantly to the need for amputation. For injections of paint, paint thinner, gasoline, oil, or jet fuel (organic solvents), the amputation risk was lower if wide surgical debridement occurred within 6 hours of injury. Steroids did not impact the amputation rate or incidence of infection. The presence of infection did not affect the incidence of amputation.

    To study metalloproteinase activity and sex steroid hormone production in serum after intra-articular glucocorticoid treatment for knee synovitis. 18 female patients with rheumatoid arthritis and synovitis of the knee with need for intra-articular glucocorticoid treatment were included in this study. Serum samples of matrix metalloproteinases (MMP-1/TIMP complex and MMP-3), dehydroepiandrosterone sulphate, testosterone, oestradiol, steroid hormone binding globulin, follicle stimulating hormone and luteinising hormone were collected before injection with 20 mg triamcinolone hexacetonide, and 24 h, 48 h, 1 week and 2 weeks after injection, respectively. Serum levels of MMP-3 were significantly decreased, but MMP-1/TIMP complex was unaffected. Dehydroepiandrosterone sulphate, testosterone and oestradiol levels all decreased and tended to return to baseline levels during the observation period. Steroid hormone binding globulin, follicle stimulating hormone and luteinising hormone levels were unchanged. Intra-articular glucocorticoid treatment causes a temporary, but considerable suppression of sex steroid hormone secretion. The reduction of MMP-3 indicates an inhibition of the inflammatory, but probably also the cartilage destructive processes within the treated joint.

    Boldenone (BOL) is an androgenic steroid that improves the growth and food conversion in food-producing animals. In most countries worldwide, this anabolic steroid is forbidden for human uses and meat production as it was developed for veterinary use. Recently, BOL is used by bodybuilders in both off season and pre-contest, where it is well known for increasing vascularity while preparing for a bodybuilding contest. The present study was designed to investigate the physiological and biochemical changes in rabbits after injection with the growth promoter BOL. A total of 32 adult New Zealand rabbits were divided into four groups, where the control group includes animals that were injected intramuscularly with olive oil and dissected after 3 weeks. The remaining three experimental groups included animals that received one, two and three intramuscular injections of 5 mg/kg body weight BOL, respectively, and were dissected after 3, 6 and 9 weeks, respectively. The animals from practice appeared healthy and did not show clinical signs of disease and none of the rabbits died during the experimental period. Serum total protein, globulin, alanine aminotransferase, asparate aminotransferase, urea, creatinine, testosterone, luteinizing hormone and follicle-stimulating hormone levels were significantly increased while serum direct bilirubin, albumin and albumin/globulin ratio were significantly decreased (p < 0.05) after one, two and three intramuscular injections of BOL as compared to their relative values in the control group. These findings explain the common phenomena in athletes and bodybuilders who suffer from infertility, renal and hepatic alterations following injection with some drugs as steroids (BOL) to build muscles. © The Author(s) 2013.

    From the middle of the 19th century, it is known that endocrine and immune systems interact bi-directionally in different processes that ensure organism homeostasis. Endocrine and nervous systems have a pivotal role in the balancing of pro- and anti-inflammatory functions of immune system, and constitute a complex circadian neuroendocrine network. Autoimmune diseases have in fact a complex pathogenic origin in which the importance of endocrine system was demonstrated. In this chapter, we will mention the structure and function of steroidal hormones involved in the neuroendocrine immune network and we will address the ways in which endocrine and immune systems influence each other, in a bi-directional fashion. Adrenal hormones, sex hormones, vitamin D, and melatonin and prolactin importantly all contribute to the homeostasis of the immune system. Indeed, some of the steroidal hormone activities determine inhibition or stimulation of immune system components, in both physiological (i.e. suppression of an unwanted response in pregnancy, or stimulation of a protective response in infections) and pathological conditions. We will finally mention the rationale for optimization of exogenous administration of glucocorticoids in chronic autoimmune diseases, and the latest developments concerning these drugs. © 2017 S.

    If a radioimmunoassay, a protein binding method, or a colorimetric assay for the assessment of a steroid level is replaced by high performance liquid chromatography (HPLC), the cost for the determination of a steroid level increases at least initially because one must acquire the new HPLC equipment. Therefore, if an older method provides the same results as the new, "advanced" HPLC method, the only advantage resulting from the introduction of a high performance chromatographic assay is that gained by the manufacturer in terms of greater sales. Thus, justification for the assessment of steroids by HPLC is only obtained if the quality and/or quantity of information gained is significantly increased as compared to that provided by the conventional methods. But this evidential relation, that more and better information justifies a higher price in any case, is no longer true in health care, with the birth some years ago of the categoric imperative for the reduction of costs in the medical sector. That is, each new technology introduced for health maintenance should demonstrate at least a stabilizing impact on total medical expenditures. Therefore, after reviewing the presently available HPLC methods for the clinically important steroids, we will consider whether HPLC analyses for these steroids can be recommended without violating this vox populi.

    This review evaluates the potential benefits as well as adverse effects from adjunctive therapy with systemic steroids in patients with pneumonia: either mild-to-moderate or severe, community-acquired or hospital-acquired, of bacterial or of viral origin (in particular H1N1 viral infection). Steroids potentially modulate the marked and persistent activation of the immune system in pneumonia. However, several recent randomized controlled trials and large prospective observational studies have repeatedly shown that steroids had no impact on survival, the clinical event of interest, but in severe pneumonia some studies pointed to potential harmful effect. In addition, adverse effects, namely hyperglycemia, superinfections, as well as increased length-of-stay, were frequent findings in the steroid-treated patients. According to the current evidence, there are no data to support the well tolerated use of systemic steroids as a standard of care in pneumonia, neither in mild-to-moderate and severe, nor in bacterial and viral infection. Clinical and basic research should work together to improve trial designs to identify reliable surrogate markers of outcome, in particular of mortality. This may improve the patient selection and facilitate the identification of subgroups that can benefit from adjunctive steroid therapy.

However, there have been no controlled prospective evaluations of epidural and nerve root contrast distribution patterns and other aspects of fluoroscopically directed lumbosacral transforaminal epidural steroid injections. To evaluate contrast flow patterns and intravascular needle placement of fluoroscopically guided lumbosacral transforaminal epidural injections. A prospective, observational study. A total of 100 consecutive patients undergoing fluoroscopically guided transforaminal epidural steroid injections were evaluated. The contrast flow patterns, ventral or dorsal epidural filling, nerve root filling, C-arm time, and intravascular needle placement were evaluated. Ventral epidural filling was seen in 88% of the procedures, in contrast to dorsal filling noted in 9% of the procedures. Nerve root filling was seen in 97% of the procedures. Total intravenous placement of the needle was noted in 22% of the procedures, whereas negative flashback and aspiration was noted in 5% of the procedures. Lumbosacral transforaminal epidural injections, performed under fluoroscopic visualization, provide excellent nerve root filling and ventral epidural filling patterns. However, unrecognized intravascular needle placement with negative flashback or aspiration was noted in 5% of the procedures.

    BACKGROUND: Steroids have proven to be of some benefit in rhinoplasty edema and ecchymosis when administered at a high and repeated dose. OBJECTIVE: To evaluate the effects of single-dose, long-acting intramuscular steroids on postoperative edema and ecchymosis after closed rhinoplasty with osteotomies compared with placebo. METHODS: A randomized, double-blinded, placebo-controlled trial was performed. Fifty-four patients were randomly assigned to two groups: 28 received a single dose of long-acting dexamethasone (mean [± SD] dose 16±4 mg) immediately before anesthetic induction; the remaining 26 received an intramuscular injection of saline solution. The same surgeon performed all surgeries, with patients under general anesthesia. Acetaminophen was the only analgesic used to control postoperative pain. High-resolution digital photographs were taken on postoperative days 1, 3, 7 and 14. Scoring was performed separately for eyelid swelling and ecchymosis by an independent observer using a graded scale (0 to 5) for edema and a scoring system (0 to 13) for ecchymosis. RESULTS: No statistically significant differences in terms of age, sex or amount of bleeding during surgery were found between the two groups. No statistically significant difference was observed in the decrease of both ecchymosis and edema between placebo and high-dose, long-acting dexamethasone. A statistically significant difference in operation time was found, favouring the steroid group. No severe complications were observed due to steroid use. DISCUSSION: Osteotomies are basically a form of (controlled) trauma, with considerable disruption of the abundant blood vessels in this facial region and, therefore, are associated with with undesirable effects. A recent meta-analysis failed to show benefits of the use of steroids after postoperative day 3. Only a trend toward reduction in edema and ecchymosis with the use of long-acting steroids compared with placebo was demonstrated in the present study

    Steroid hormones are involved in the regulation of a variety of processes like embryonic development, sex differentiation, metabolism, immune responses, circadian rhythms, stress response, and reproduction in vertebrates. Teleost fishes and humans show a remarkable conservation in many developmental and physiological aspects, including the endocrine system in general and the steroid hormone related processes in particular. This review provides an overview of the current knowledge about steroid hormone biosynthesis and the steroid hormone receptors in teleost fishes and compares the findings to the human system. The impact of the duplicated genome in teleost fishes on steroid hormone biosynthesis and perception is addressed. Additionally, important processes in fish physiology regulated by steroid hormones, which are most dissimilar to humans, are described. We also give a short overview on the influence of anthropogenic endocrine disrupting compounds on steroid hormone signaling and the resulting adverse physiological effects for teleost fishes. By this approach, we show that the steroidogenesis, hormone receptors, and function of the steroid hormones are reasonably well understood when summarizing the available data of all teleost species analyzed to date. However, on the level of a single species or a certain fish-specific aspect of physiology, further research is needed. Copyright © 2015 Elsevier Inc. All rights reserved.

    Kaposi's sarcoma has been reported in patients receiving immunosuppressive therapy, most of whom are organ transplant recipients. The development of Kaposi's sarcoma after treatment with corticosteroids has been reported in only 38 patients who have not had acquired immunodeficiency syndrome or undergone organ transplantation. Cutaneous Kaposi's sarcoma developed 2 months after intraarticular steroid injections in a man with ulnar nerve entrapment. The lesions regressed spontaneously after 3 months but reappeared with visceral involvement 18 months later, shortly after initiation of a course of epidural steroid injections for treatment of low back pain. The cutaneous lesions and some visceral lesions rapidly regressed after cessation of treatment.

    To compare short-term outcomes and procedure times for intra-articular steroid injection (IASI) to the temporomandibular joint (TMJ) with and without the use of intraoperative image guidance for patients with juvenile idiopathic arthritis (JIA). This is a retrospective study of children with JIA who underwent TMJ IASI at Boston Children's Hospital (Boston, MA). Patients were divided into groups according to IASI technique: 1) "landmark" group if performed by an oral and maxillofacial surgeon using an anatomic landmark technique with no intraoperative image guidance or 2) "image-guided" group if performed by an interventional radiologist using intraoperative ultrasound and computed tomography. Predictor variables included IASI technique (landmark vs image guided), age, gender, JIA subtype, category of medications for arthritis, and presence of family history of autoimmune disease. Outcome variables were changes in patient-reported pain, maximal incisal opening (MIO), synovial enhancement ratio (ER), and total procedure time. Forty-five patients with 71 injected TMJs were included. Twenty-two patients with 36 injected TMJs were in the landmark group and 23 patients with 35 injected joints were in the image-guided group. There were no relevant differences in age, gender, family history of rheumatologic disease, or disease subtype between groups. There were no differences in resolution of pain (P = 1.00), increase in MIO (P = .975), or decrease in ER (P = .492) between groups, but procedure times averaged 49 minutes longer for the image-guided group (P < .008). There were no statistical differences in short-term outcomes, but procedure times were longer for the image-guided group. Although specific indications for the use of image guidance might exist, routine use of this procedure cannot be justified. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

    There is a growing need for compressed air free of entrained oil to be used in industry. In many cases it can be supplied by oil flooded screw compressors with multi stage filtration systems, or by oil free screw compressors. However, if water injected screw compressors can be made to operate reliably, they could be more efficient and therefore cheaper to operate. Unfortunately, to date, such machines have proved to be insufficiently reliable and not cost effective. This paper describes an investigation carried out to determine the current limitations of water injected screw compressor systems and how these could be overcome in the 15-315 kW power range and delivery pressures of 6-10 bar. Modern rotor profiles and approach to sealing and cooling allow reasonably inexpensive air end design. The prototype of the water injected screw compressor air system was built and tested for performance and reliability. The water injected compressor system was compared with the oil injected and oil free compressor systems of the equivalent size including the economic analysis based on the lifecycle costs. Based on the obtained results, it was concluded that water injected screw compressor systems could be designed to deliver clean air free of oil contamination with a better user value proposition than the oil injected or oil free screw compressor systems over the considered range of operations.

    Lipidots are original nanoparticulate lipid delivery vectors for drugs and contrast agents made from materials generally regarded as safe. Here, we characterized the in vivo stability, biodistribution, and pharmacokinetics of lipidots. Lipidots 55 nm in diameter and coated with a phospholipid/poly(ethyleneglycol) surfactant shell were triply labeled with (3)H-cholesteryl-hexadecyl-ether, cholesteryl-(14)C-oleate, and the 1,1'-dioctadecyl-3,3,3',3'-tetramethylindotricarbocyanine infrared fluorescent dye and injected intravenously into immunocompetent Friend virus B-type mice. The pharmacokinetics and biodistribution of lipidots were analyzed quantitatively in serial samples of blood and tissue and with in vivo optical imaging and were refined by microscopic examination of selected target tissues. The plasmatic half-life of lipidots was approximately 30 min. Radioactive and fluorescent tracers displayed a similar nanoparticle-driven biodistribution, indicative of the lipidots' integrity during the first hours after injection. Lipidots distributed in the liver and, surprisingly, in the steroid-rich organs adrenals and ovaries, but not in the spleen. This tropism was confirmed at the microscopic level by histologic detection of 1,1'-dioctadecyl-3,3,3',3'-tetramethylindotricarbocyanine. Nanoparticle loading with cholesterol derivatives increased accumulation in ovaries in a dose-dependent manner. This previously unreported distribution pattern is specific to lipidots and attributed to their nanometric size and composition, conferring on them a lipoproteinlike behavior. The affinity of lipidots for steroid hormone-rich areas is of interest to address drugs and contrast agents to lipoprotein-receptor-overexpressing cancer cells found in hormone-dependent tumors.

    Bacteria frequently found in equine urine samples may cause degradation of 17beta-OH steroids. A simple liquid chromatography/tandem mass spectrometry (LC/MS/MS) method has been developed to evaluate the microbiological contamination of equine urine as a marker of poor storage conditions. Norethandrolone was used as the internal standard, and the linearity, sensitivity, precision and accuracy of the method were evaluated. 17beta-OH oxidation was demonstrated for testosterone, nandrolone, trenbolone and boldenone, but did not occur in alpha-epimers such as alpha-boldenone and epitestosterone, demonstrating the stereoselectivity of the reaction. A rapid test was performed by spiking one of the four 17beta-OH steroids in samples of diluted equine urine. The steroids were transformed into their respective ketones in the presence of bacterial activity. The test allows direct injection of diluted samples into the LC/MS system, without the need for prior extraction. Results show that the best method of storage is freezing at -18 degrees C. Urine specimens should be analyzed as soon as possible after thawing. This allows bacterial degradation of equine urine to be arrested temporarily, so that the urine can be used for qualitative or quantitative analysis of 17beta-OH steroids.

    Intraarticular steroid injections are a common first-line therapy for severe osteoarthritis, which affects an estimated 27 million people in the United States. Although topical, oral, intranasal, and inhalational steroids are known to increase intraocular pressure in some patients, the effect of intraarticular steroid injections on intraocular pressure has not been investigated, to the best of our knowledge. If elevated intraocular pressure is sustained for long periods of time or is of sufficient magnitude acutely, permanent loss of the visual field can occur. How does intraocular pressure change 1 week after an intraarticular knee injection either with triamcinolone acetonide or hyaluronic acid? A nonrandomized, nonblinded prospective cohort study was conducted at an outpatient, ambulatory orthopaedic clinic. This study compared intraocular pressure elevation before and 1 week after intraarticular knee injection of triamcinolone acetonide versus hyaluronic acid for management of primary osteoarthritis of the knee. Patients self-selected to be injected in their knee with either triamcinolone acetonide or hyaluronic acid before being informed of the study. The primary endpoint was intraocular pressure elevation of ≥ 7 mm Hg 1 week after injection. This cutoff is determined as the minimum significant pressure change in the ophthalmology literature recognized as an intermediate responder to steroids. Intraocular pressure was measured using a handheld Tono-Pen® applanation device. This device is frequently used in intraocular pressure measurement in clinical and research settings; 10 sequential measurements are obtained and averaged with a confidence interval. Only measurements with a 95% confidence interval were used. Over a 6-month period, a total of 96 patients were approached to enroll in the study. Sixty-two patients out of 96 approached (65%) agreed. Thirty-one (50%) were injected with triamcinolone and 31 (50%) were injected with hyaluronic acid. Patients

    The inflow, transformation, and attenuation of natural steroid hormones and phytoestrogens and estrogenic activity were assessed across the lagoon/sprayfield system of a prototypical commercial swine sow operation. Free and conjugated steroid hormones (estrogens, androgens, and progesterone) were detected in urine and feces of sows across reproductive stages, with progesterone being the most abundant steroid hormone. Excreta also contained phytoestrogens indicative of a soy-based diet, particularly, daidzein, genistein, and equol. During storage in barn pits and the anaerobic lagoon, conjugated hormones dissipated, and androgens and progesterone were attenuated. Estrone and equol persisted along the waste disposal route. Following application of lagoon slurry to agricultural soils, all analytes exhibited attenuation within 2 days. However, analytes including estrone, androstenedione, progesterone, and equol remained detectable in soil at 2 months postapplication. Estrogenic activity in the yeast estrogen screen and T47D-KBluc in vitro bioassays generally tracked well with analyte concentrations. Estrone was found to be the greatest contributor to estrogenic activity across all sample types. This investigation encompasses the most comprehensive suite of natural hormone and phytoestrogen analytes examined to date across a livestock lagoon/sprayfield and provides global insight into the fate of these analytes in this widely used waste management system.

    The purpose of this study was to evaluate the analgesic effect of botulinum toxin A (BoNTA) injections in patients with myofascial pain syndrome (MPS) who were previously treated with the local infiltration of anesthetic and steroids (LIAS). The study included a retrospective phase and a longitudinal open-label prospective phase, which were conducted on consecutive patients with MPS previously treated with the local infiltration of anesthetic (levobupivacaíne 0.25%) and steroids (triamcinolone 40 mg). Eligible patients were treated with a single intramuscular injection of BoNTA (Botox; Allergan, Inc., Irvine, CA). The treatment efficacy was determined according to the degree of pain relief obtained. Eighty-two patients met the inclusion/exclusion criteria and were included in the study. Successful results were obtained for 32 (39.0%) and 30 (36.6%) patients, during treatment with BoNTA and LIAS, respectively. The mean (standard deviation) length of the analgesic effect was significantly longer with BoNTA (29.6 [SD = 17.7] weeks) than with LIAS (8.5 [SD = 6.4] weeks), P <.0001. As regards the side effects, 19 (23.2%) patients reported transient soreness at the injection site for 2 to 3 days with BoNTA. The MPS patients previously treated with a local infiltration of anesthetic and steroids who then received a single injection of BoNTA experienced significantly reduced pain for a relatively long time.

    Loss of bone microstructure integrity is thought to be related to osteonecrosis. But the relationship between the time when bone microstructure integrity loss appears and the onset of osteonecrosis has not yet been determined. Our study demonstrated abnormal changes of subchondral bone microstructure involved in the early pathogenesis of osteonecrosis. Using a rabbit model, we investigated the changes of subchondral bone microstructure following steroid administration to identify the onset of abnormal bone microstructure development in steroid-induced osteonecrosis. Fifty-five adult female Japanese White rabbits (mean body weight 3.5 kg; mean age 24 months) were used and randomly divided among three time points (3, 7, and 14 days) consisting of 15 rabbits each, received a single intramuscular injection of methylprednisolone acetate (MP; Pfizer Manufacturing Belgium NV) at a dose of 4 mg/kg, and a control group consisting of 10 rabbits was fed and housed under identical conditions but were not given steroid injections. A micro-CT scanner was applied to detect changes in the trabecular region of subchondral bone of excised femoral head samples. Parameters including bone volume fraction (BV/TV), bone surface (BS), trabecular bone pattern factor (Tb.Pf), trabecular thickness/number/separation (Tb.Th, Tb.N, and Tb.Sp), and structure model index (SMI) were evaluated using the software CTAn (SkyScan). After micro-CT scans, bilateral femoral heads were cut in the coronal plane at a thickness of 4 μm. The sections were then stained with haematoxylin-eosin and used for the diagnosis of osteonecrosis and the rate of development of osteonecrosis. The BV/TV, BS, Tb.Th and Tb.N demonstrated a time-dependent decline from 3, 7, and 14 days compared with the control group, while the Tb.Pf, Tb.Sp and SMI demonstrated an increase at 3, 7, and 14 days compared with the control group. For the histopathology portion, osteonecrosis was not seen 3 days after steroid treatment, but was

    The objective of our study was to correlate patterns of injury on preprocedural MRI with outcome after targeted fluoroscopy-guided steroid and local anesthetic injection of the symphysis pubis and its muscular attachments in a group of athletes with chronic groin pain. Forty-five patients with chronic sports-related groin pain underwent MRI of the pelvis and a targeted fluoroscopy-guided symphyseal corticosteroid and local anesthetic injection. Preprocedural MRI was reviewed. The presence or absence of a "superior cleft" sign (i.e., rectus abdominis-adductor longus attachment microtearing), "secondary cleft" sign (i.e., short adductor [gracilis, adductor brevis, and pectineus muscles] attachment microtearing), osteitis pubis, and extrasymphyseal pelvic abnormalities was recorded. Patients were followed up a mean time of 23 months after the procedure, and outcome was recorded. Correlation was made between preprocedural MRI findings and outcome. Forty-two percent of the patients had an isolated superior cleft sign, 7% had an isolated secondary cleft sign, and 11% had isolated osteitis pubis. Thirty-one percent of patients had a more complex injury, and 9% had a normal symphysis pubis. Overall, 89% of the patients experienced an improvement in symptoms. The response was sustained after a minimum of 6 months in 58% of the patients. The presence of the superior cleft sign was more frequently associated with a complete recovery. Fluoroscopy-guided corticosteroid symphyseal injection is a safe and effective treatment of sports-related groin pain. It is more frequently associated with a complete recovery in patients who display an isolated superior cleft sign on MRI. MRI not only is useful in characterizing groin injuries but also may be helpful in predicting response to therapeutic injection.

    The aim of the present study was to verify the efficacy and the safety of intratympanic dexamethasone to treat sudden sensorineural hearing loss as salvage therapy. A prospective study was conducted on patients affected by idiopathic sudden hearing loss who were treated before with some systemic therapy, but without recovery of the hearing The patients able to undergo the study, but who refused salvage treatment were considered as control group. A solution of Dexamethasone 4 mg/ml was then injected through the posterior-inferior quadrant filling completely the middle ear. The follow-up in the following 6 months included an audiogram every month. The number of patients treated with salvage therapy was 36. The patients who refused treatment were further 10. The salvage treatment was done with a mean delay of 24.3 days from the onset of symptoms. Mean hearing threshold after the onset of sudden hearing loss at PTA was 66.5 dB. After the failed treatment the mean PTA was 59.6 dB. The mean PTA after the intratympanic steroid administration was 46.8 dB, with a mean improvement of 12.8 dB. No hearing change was noted in the 10 patients who refused salvage therapy. The patients that assumed systemic steroid as first therapy showed a better PTA threshold after the salvage intratympanic treatment (p<0.01). A significant difference (p<0.05) of hearing recovery was evidenced between non-smoker patients and those with smoking habit. Our data showed that a salvage treatment with intratympanic dexamethasone should be suggested to all patients who failed the first systemic treatment. The systemic steroid therapy done before the salvage treatment seems to exert a protective role for the inner ear, as shown by our series. On the contrary the smoke habit is a negative prognostic factor in the hearing recovery. Copyright © 2013 Elsevier Inc. All rights reserved.

    In vitro studies of CWR22 tumor cells lack steroid specificity. We sought to determine if CWR22 xenografts also lack steroid specificity. We injected castrated nude mice with CWR22 tumor cells (6 x 10(6) cells) and implanted Alzet osmotic pumps that delivered approximately 1 mg steroid/kg body weight/day. Serum PSA levels were detectable in intact mice and castrated mice treated with testosterone (T), but not in those treated with estradiol (E(2)), progesterone (P), or flutamide (F). T maintained mean tumor weight similar to that in intact mice (P = NS). We observed no tumors in castrated mice or mice treated with E(2), P, or F, and tumor histology was consistent with weights. The mutation of the androgen receptor (H874Y) that occurs in the CWR22 xenograft model of human prostate cancer does not significantly affect in vivo steroid specificity for E(2), P, or F.

    Objective Arthritis of the knee affects 46 million Americans. We aimed to determine the level of evidence of intraarticular knee injections in the management of arthritic knee pain. Methods We systematically searched PUBMED/MEDLINE and the Cochrane databases for articles published on knee injections and evaluated their level of evidence and recommendations according to established criteria. Results The evidence supports the use of intraarticular corticosteroid injections for rheumatoid arthritis (1A+ level), osteoarthritis (1A+ level), and juvenile idiopathic arthritis (2C+ level). Pain relief and functional improvement are significant for months up to one year after the injection. Triamcinolone hexacetonide offers an advantage over triamcinolone acetonide and should be the intraarticular steroid of choice (2B+ level). Intraarticular injection of hyaluronate may provide longer pain relief than steroid injection in osteoarthritis (2B+ level). It can also be effective for rheumatoid arthritis knee pain (1A+ level). However, it is only recommended for patients with significant surgical risk factors and for patients with mild radiographic disease in whom conservative treatment has failed (2B± level). Botulinum toxin Type A injection is effective in reducing arthritic knee pain (2B+ level) and so is tropisetron (2B+ level) and tanezumab (2B+ level). The new agents, such as rAAV2-TNFR:Fc, SB-210396/CE 9.1, and various radioisotopes have provided various degrees of success, but their long-term safety and efficacy remains to be determined. Conclusions We conclude that strong evidence supports the use of intraarticular knee injection as a valuable intervention in the continuum of management of arthritis between conservative treatment and knee surgeries.

    Local steroids have been used as an adjuvant therapy to patients undergoing internal urethrotomy (IU) in treating urethral strictures. Whether this technique is effective and safe is still controversial. The aim of this study is to determine the efficacy and safety of local steroids as applied with the IU procedure. A systematic review of the literature was performed by searching Medline, Embase, Cochrane Library Databases, and the Web of Science. We included only prospective randomized, controlled trials that compared the efficacy and safety between IU procedures with applied local steroids and those without. Eight studies were found eligible for further analysis. In total, 203 patients undergoing IU were treated with steroid injection or catheter lubrication. Time to recurrence is statistically significant (mean: 10.14 and 5.07 months, P<0.00001).The number of patients with recurrent stricture formation significantly decreased at different follow-up time points (P=0.05).No statistically significant differences were found between the recurrence rates, adverse effects, and success rates of second IUs in patients with applied local steroids and those without. The use of local steroids with IU seems to prolong time to stricture recurrence but does not seem to affect the high stricture recurrence rate following IU. When local steroids are applied with complementary intention, the disease control outcomes are encouraging. Further robust comparative effectiveness studies are now required.

    To explore the expression of P-glycoprotein (P-gp) in the peripheral blood nucleated cells (PBNCs) of children with nephrotic syndrome in relation to their clinical response to glucocorticoid treatment. Thirty-six children with nephrotic syndrome (20 cases of steroid-responsive and 16 cases of steroid-resistant) were examined. All the participants were subjected to complete history taking, thorough clinical examination, laboratory investigations (24-h urinary protein, serum albumin, complete blood count with differential white blood cell count, serum cholesterol, serum urea, serum creatinine) and functional assay of P-gp using FACS Calibur flowcytometry. P-gp assay was done in both groups during remission. P-gp activity was significantly higher in steroid-resistant than steroid-sensitive cases. P-gp can be used as a predictor of outcome, as a part of laboratory evaluation of the cases before starting steroid therapy, so as to determine whether to use alternative line of therapy or use one of the P-gp inhibitors with steroid therapy.

    Sensitive, specific, and reproducible methods for the quantitative determination of eight anabolic steroids in guinea pig hair have been developed using LC/MS/MS and GC/MS/MS. Methyltestosterone, stanozolol, methandienone, nandrolone, trenbolone, boldenone, methenolone and DHEA were administered intraperitoneally in guinea pigs. After the first injection, black hair segments were collected on shaved areas of skin. The analysis of these segments revealed the distribution of anabolic steroids in the guinea pig hair. The major components in hair are the parent anabolic steroids. The time courses of the concentrations of the steroids in hair (except methenolone, which does not deposit in hair) demonstrated that the peak concentrations were reached on days 2-4, except stanozolol, which peaked on day 10 after administration. The concentrations in hair appeared to be related to the physicochemical properties of the drug compound and to the dosage. These studies on the distribution of drugs in the hair shaft and on the time course of their concentration changes provide information relevant to the optimal time and method of collecting hair samples. Such studies also provide basic data that will be useful in the application of hair analysis in the control of doping and in the interpretation of results.

PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were searched for studies published in all languages from 1984 to January 2009. Additional studies were identified from cited references. Selection criteria Randomised controlled trials that compared steroids with the combination of steroids and antivirals for the treatment of Bell's palsy were included in this study. At least one month of follow-up and a primary end point of at least partial facial muscle recovery, as defined by a House-Brackmann grade of at least 2 (complete palsy is designated a grade of 6) or an equivalent score on an alternative recognised scoring system, were required. Review methods Two authors independently reviewed studies for methodological quality, treatment regimens, duration of symptoms before treatment, length of follow-up, and outcomes. Odds ratios with 95% confidence intervals were calculated and pooled using a random effects model. Six trials were included, a total of 1145 patients; 574 patients received steroids alone and 571 patients received steroids and antivirals. The pooled odds ratio for facial muscle recovery showed no benefit of steroids plus antivirals compared with steroids alone (odds ratio 1.50, 95% confidence interval 0.83 to 2.69; P=0.18). A one study removed analysis showed that the highest quality studies had the greatest effect on the lack of difference between study arms shown by the odds ratio. Subgroup analyses assessing causes of heterogeneity defined a priori (time from symptom onset to treatment, length of follow-up, and type of antiviral studied) showed no benefit of antivirals in addition to that provided by steroids. Antivirals did not provide an added benefit in achieving at least partial facial muscle recovery compared with steroids alone in patients with

    Steroid sulfation and desulfation are fundamental pathways vital for a functional vertebrate endocrine system. After biosynthesis, hydrophobic steroids are sulfated to expedite circulatory transit. Target cells express transmembrane organic anion-transporting polypeptides that facilitate cellular uptake of sulfated steroids. Once intracellular, sulfatases hydrolyze these steroid sulfate esters to their unconjugated, and usually active, forms. Because most steroids can be sulfated, including cholesterol, pregnenolone, dehydroepiandrosterone, and estrone, understanding the function, tissue distribution, and regulation of sulfation and desulfation processes provides significant insights into normal endocrine function. Not surprisingly, dysregulation of these pathways is associated with numerous pathologies, including steroid-dependent cancers, polycystic ovary syndrome, and X-linked ichthyosis. Here we provide a comprehensive examination of our current knowledge of endocrine-related sulfation and desulfation pathways. We describe the interplay between sulfatases and sulfotransferases, showing how their expression and regulation influences steroid action. Furthermore, we address the role that organic anion-transporting polypeptides play in regulating intracellular steroid concentrations and how their expression patterns influence many pathologies, especially cancer. Finally, the recent advances in pharmacologically targeting steroidogenic pathways will be examined. PMID:26213785

    It has been widely reported that the incidence and the severity of natural parasitic infections are different between males and females of several species, including humans. This sexual dimorphism involves a distinct exposure of males and females to various parasite infective stages, differential effects of sex steroids on immune cells, and direct effects of these steroids on parasites, among others. Typically, for a large number of parasitic diseases, the prevalence and intensity is higher in males than females; however, in several parasitic infections, males are more resistant than females. In the present work, we review the effects of sex hormones on immunity to protozoa and helminth parasites, which are the causal agents of several diseases in humans, and discuss the most recent research related to the role of sex steroids in the complex host-parasite relationship. © 2012 New York Academy of Sciences.

    There is continued debate on the effectiveness, indications, and medical necessity of epidural injections in managing pain and disability from lumbar disc herniation, despite extensive utilization. There is paucity of literature on interlaminar epidural injections in managing lumbar disc herniation or radiculitis in contemporary interventional pain management settings utilizing fluoroscopy. A randomized, double-blind, active-control trial was undertaken to assess the effectiveness of lumbar interlaminar epidural injections with or without steroids for disc herniation and radiculitis. The primary outcome was defined as pain relief and functional status improvement of ≥ 50%. One hundred twenty patients were randomly assigned to 1 of the 2 groups. Group I patients received lumbar interlaminar injections containing a local anesthetic (lidocaine 0.5%, 6 mL), whereas Group II patients received lumbar interlaminar epidural injections of 0.5% lidocaine, 5 mL, mixed with 1 mL of non-particulate betamethasone. In the patients who responded with initial 2 procedures with at least 3 weeks of relief, significant improvement was seen in 80% of the patients in the local anesthetic group and 86% of the patients in the local anesthetic and steroid group. The overall average procedures per year were 3.6 in the local anesthetic group and 4.1 in the local anesthetic and steroid group, with an average relief of 33.7 ± 18.1 weeks in the local anesthetic group and 39.1 ± 12.2 weeks in the local anesthetic and steroid group over a period of 52 weeks in the overall population. Lumbar interlaminar epidural injections of local anesthetic with or without steroids might be effective in patients with disc herniation or radiculitis, with potential superiority of steroids compared with local anesthetic alone at 1 year follow-up. © 2012 The Authors Pain Practice © 2012 World Institute of Pain.

    A chemical analysis technique known as flow injection analysis, wherein small quantities of chemical reagents and sample are intermixed and reacted within a capillary flow system and the reaction products are detected optically, electrochemically, or by other means. A highly miniaturized version of a flow injection analysis system has been fabricated utilizing microfabrication techniques common to the microelectronics industry. The microflow system uses flow capillaries formed by etching microchannels in a silicon or glass wafer followed by bonding to another wafer, commercially available microvalves bonded directly to the microflow channels, and an optical absorption detector cell formed near the capillary outlet, with light being both delivered and collected with fiber optics. The microflow system is designed mainly for analysis of liquids and currently measures 38.times.25.times.3 mm, but can be designed for gas analysis and be substantially smaller in construction.

    The ability of steroid hormones to rapidly influence cell physiology through nongenomic mechanisms raises the possibility that these molecules may play a role in the dynamic regulation of social behavior, particularly in species in which social stimuli can rapidly influence circulating steroid levels. We therefore tested if testosterone (T), which increases in male goldfish in response to sexual stimuli, can rapidly influence approach responses towards females. Injections of T stimulated approach responses towards the visual cues of females 30-45 min after the injection but did not stimulate approach responses towards stimulus males or affect general activity, indicating that the effect is stimulus-specific and not a secondary consequence of increased arousal. Estradiol produced the same effect 30-45 min and even 10-25 min after administration, and treatment with the aromatase inhibitor fadrozole blocked exogenous T's behavioral effect, indicating that T's rapid stimulation of visual approach responses depends on aromatization. We suggest that T surges induced by sexual stimuli, including preovulatory pheromones, rapidly prime males to mate by increasing sensitivity within visual pathways that guide approach responses towards females and/or by increasing the motivation to approach potential mates through actions within traditional limbic circuits.

    Steroid and local anaesthetic injection to the acromioclavicular joint (ACJ) is a very common diagnostic and therapeutic procedure, which is often performed in the outpatient department. However, it can be difficult to localize this joint because of its small size, presence of osteophytes and variable morphology in the population. We performed a study to determine whether the use of an image intensifier (X-ray guidance), in theatre, improves the accuracy of this injection. This was a prospective study carried out between March 2014 and March 2015. The injections were performed by two senior orthopaedic surgeons. First, we clinically palpated the ACJ and marked the area over this point as A. Then, with the use of a needle and an image intensifier in a single plane, we identified the actual location of the ACJ and marked this point as B. We measured the distance between A and B in millimetres (mm) and determined the accuracy of the injections. Further analysis taking into account the ACJ capsular attachments was also performed. In total, 45 patients and 50 injections were included in the study; five patients had repeated injections at different times. We found that only 12 injections (24%) were palpated to be correct with no discrepancies between A and B (95% confidence interval: 14-37%). For the remaining 38 injections (76%), the use of an image intensifier had significantly improved the accuracy of ACJ location ( p < 0.05). Taking the capsular attachments of the ACJ into consideration reduced the number of inaccurate injections to 27 (54%). We recommend the use of an image intensifier (or ultrasound guidance) to accurately determine the location of the ACJ for steroid and local anaesthetic injections. This prevents an injection into the wrong place, which can lead to wrong diagnosis and/or suboptimal treatment.

    In recent years a new picture of human sperm biology is emerging. It is now widely recognized that sperm contain nuclear encoded mRNA, mitochondrial encoded RNA and different transcription factors including steroid receptors, while in the past sperm were considered incapable of transcription and translation. One of the main targets of steroid hormones and their receptors is reproductive function. Expression studies on Progesterone Receptor, estrogen receptor, androgen receptor and their specific ligands, demonstrate the presence of these systems in mature spermatozoa as surface but also as nuclear conventional receptors, suggesting that both systemic and local steroid hormones, through sperm receptors,more » may influence male reproduction. However, the relationship between the signaling events modulated by steroid hormones and sperm fertilization potential as well as the possible involvement of the specific receptors are still controversial issues. The main line of this review highlights the current research in human sperm biology examining new molecular systems of response to the hormones as well as specific regulatory pathways controlling sperm cell fate and biological functions. Most significant studies regarding the identification of steroid receptors are reported and the mechanistic insights relative to signaling pathways, together with the change in sperm metabolism energy influenced by steroid hormones are discussed.The reviewed evidences suggest important effects of Progesterone, Estrogen and Testosterone and their receptors on spermatozoa and implicate the involvement of both systemic and local steroid action in the regulation of male fertility potential. - Highlights: • One of the main targets of steroid hormones and their receptors is reproductive function. • Pg/PR co-work to stimulate enzymatic activities to sustain a capacitation process. • E2/ERs regulate sperm motility, capacitation and acrosome reaction and act as survival factors.

    Over the past two decades, the classical understanding of steroid action has been updated to include rapid, membrane-initiated, neurotransmitter-like functions. While steroids were known to function on very short time spans to induce physiological and behavioral changes, the mechanisms by which these changes occur are now becoming more clear. In avian systems, rapid estradiol effects can be mediated via local alterations in aromatase activity, which precisely regulates the temporal and spatial availability of estrogens. Acute regulation of brain-derived estrogens has been shown to rapidly affect sensorimotor function and sexual motivation in birds. In rodents, estrogens and progesterone are critical for reproduction, including preovulatory events and female sexual receptivity. Membrane progesterone receptor as well as classical progesterone receptor trafficked to the membrane mediate reproductive-related hypothalamic physiology, via second messenger systems with dopamine-induced cell signals. In addition to these relatively rapid actions, estrogen membrane-initiated signaling elicits changes in morphology. In the arcuate nucleus of the hypothalamus, these changes are needed for lordosis behavior. Recent evidence also demonstrates that membrane glucocorticoid receptor is present in numerous cell types and species, including mammals. Further, membrane glucocorticoid receptor influences glucocorticoid receptor translocation to the nucleus effecting transcriptional activity. The studies presented here underscore the evidence that steroids behave like neurotransmitters to regulate CNS functions. In the future, we hope to fully characterize steroid receptor-specific functions in the brain. PMID:27911748

    In this article, we examine evidence supporting the role of reproductive steroids in the regulation of mood and behavior in women and the nature of that role. In the first half of the article, we review evidence for the following: (i) the reproductive system is designed to regulate behavior; (ii) from the subcellular to cellular to circuit to behavior, reproductive steroids are powerful neuroregulators; (iii) affective disorders are disorders of behavioral state; and (iv) reproductive steroids affect virtually every system implicated in the pathophysiology of depression. In the second half of the article, we discuss the diagnosis of the three reproductive endocrine-related mood disorders (premenstrual dysphoric disorder, postpartum depression, and perimenopausal depression) and present evidence supporting the relevance of reproductive steroids to these conditions. Existing evidence suggests that changes in reproductive steroid levels during specific reproductive states (i.e., the premenstrual phase of the menstrual cycle, pregnancy, parturition, and the menopause transition) trigger affective dysregulation in susceptible women, thus suggesting the etiopathogenic relevance of these hormonal changes in reproductive mood disorders. Understanding the source of individual susceptibility is critical to both preventing the onset of illness and developing novel, individualized treatments for reproductive-related affective dysregulation. © 2016 American Physiological Society.

    1997-07-01

    A chemical analysis technique known as flow injection analysis is described, wherein small quantities of chemical reagents and sample are intermixed and reacted within a capillary flow system and the reaction products are detected optically, electrochemically, or by other means. A highly miniaturized version of a flow injection analysis system has been fabricated utilizing microfabrication techniques common to the microelectronics industry. The microflow system uses flow capillaries formed by etching microchannels in a silicon or glass wafer followed by bonding to another wafer, commercially available microvalves bonded directly to the microflow channels, and an optical absorption detector cell formed near the capillary outlet, with light being both delivered and collected with fiber optics. The microflow system is designed mainly for analysis of liquids and currently measures 38{times}25{times}3 mm, but can be designed for gas analysis and be substantially smaller in construction. 9 figs.

    Effects of a single injection of 17β-estradiol (E2), testosterone (T), or 5β-dihydrotestosterone (DHT) on expression of genes central to the growth hormone (GH)/insulin-like growth factor (IGF) axis, muscle-regulatory factors, transforming growth factor-beta (TGFβ) superfamily signaling cascade, and estrogen receptors were determined in rainbow trout (Oncorhynchus mykiss) liver and white muscle tissue. In liver in addition to regulating GH sensitivity and IGF production, sex steroids also affected expression of IGF binding proteins, as E2, T, and DHT increased expression of igfbp2b and E2 also increased expression of igfbp2 and igfbp4. Regulation of this system also occurred in white muscle in which E2 increased expression of igf1, igf2, and igfbp5b1, suggesting anabolic capacity may be maintained in white muscle in the presence of E2. In contrast, DHT decreased expression of igfbp5b1. DHT and T decreased expression of myogenin, while other muscle regulatory factors were either not affected or responded similarly for all steroid treatments. Genes within the TGFβ superfamily signaling cascade responded to steroid treatment in both liver and muscle, suggesting a regulatory role for sex steroids in the ability to transmit signals initiated by TGFβ superfamily ligands, with a greater number of genes responding in liver than in muscle. Estrogen receptors were also regulated by sex steroids, with era1 expression increasing for all treatments in muscle, but only E2- and T-treatment in liver. E2 reduced expression of erb2 in liver. Collectively, these data identify how physiological mechanisms are regulated by sex steroids in a manner that promotes the disparate effects of androgens and estrogens on growth in salmonids.

    This review aims to evaluate the role of anaesthetics, steroids and platelet-rich plasma (PRP) employed with ultrasound-guided injection in the management of musculoskeletal pathology of the extremities. Ultrasound-guided injection represents an interesting and minimally invasive solution for the treatment of tendon and joint inflammatory or degenerative diseases. The availability of a variety of new drugs such as hyaluronic acid and PRP provides expansion of the indications and therapeutic possibilities. The clinical results obtained in terms of pain reduction and functional recovery suggest that the use of infiltrative procedures can be a good therapeutic alternative in degenerative and inflammatory joint diseases.

    It is important to profile steroids in many physiological and pathological processes. Recently, hair has been used for the long-term measurement of endogenous steroid hormones. Analyzing hair has advantages of being noninvasive and time sequential compared with other bio-specimens. Liquid chromatography-mass spectrometry (LC-MS) techniques have been widely used over the past decades; however, it is challenging to profile estrogens in hair by LC-MS, and more comprehensive steroid profiling is required. In this paper, an ultra high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed to simultaneously profile 28 multifunctional steroids, including corticosteroids (n = 6), estrogens (n = 13), androgens (n = 5) and progestogens (n = 4), in human scalp hair in a single run. To optimize the sample preparation procedure, we evaluated extraction time, post-incubation purification and hair fragment length; 30 mg hair samples were washed with hexane, cut into 5 mm pieces and incubated in methanol for 18 h at 25 °C. Methanol extraction derivatized using Girard P and dansyl chloride reagent was analyzed within 25 min using an automated injection program combined with a diverter valve switch and step analysis (AIDSA). The method was well validated in terms of linearity, limit of detection (LOD), limit of quantification (LOQ), precision, accuracy, matrix effect and recovery, and was successfully applied to a steroid profile from male and female hairs. Significant differences were observed between genders. In addition, steroids showed a declining trend from the proximal to more distal hair segments; thus, care should be taken when obtaining hair samples for analysis to account for this difference in steroid levels along the length of hair.

    Objective To determine whether steroids plus antivirals provide a better degree of facial muscle recovery in patients with Bell’s palsy than steroids alone. Design Meta-analysis. Data sources PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were searched for studies published in all languages from 1984 to January 2009. Additional studies were identified from cited references. Selection criteria Randomised controlled trials that compared steroids with the combination of steroids and antivirals for the treatment of Bell’s palsy were included in this study. At least one month of follow-up and a primary end point of at least partial facial muscle recovery, as defined by a House-Brackmann grade of at least 2 (complete palsy is designated a grade of 6) or an equivalent score on an alternative recognised scoring system, were required. Review methods Two authors independently reviewed studies for methodological quality, treatment regimens, duration of symptoms before treatment, length of follow-up, and outcomes. Odds ratios with 95% confidence intervals were calculated and pooled using a random effects model. Results Six trials were included, a total of 1145 patients; 574 patients received steroids alone and 571 patients received steroids and antivirals. The pooled odds ratio for facial muscle recovery showed no benefit of steroids plus antivirals compared with steroids alone (odds ratio 1.50, 95% confidence interval 0.83 to 2.69; P=0.18). A one study removed analysis showed that the highest quality studies had the greatest effect on the lack of difference between study arms shown by the odds ratio. Subgroup analyses assessing causes of heterogeneity defined a priori (time from symptom onset to treatment, length of follow-up, and type of antiviral studied) showed no benefit of antivirals in addition to that provided by steroids. Conclusions Antivirals did not provide an added benefit in achieving at least partial facial muscle

    Prospective cohort study. Although lumbar radiculopathy is regarded as a specific diagnosis, the most effective treatment strategy is unclear. Commonly used treatments include transforaminal epidural steroid injections (TESIs) and Mechanical Diagnosis & Therapy (MDT), but no studies have investigated the effectiveness of this combination. MDT differentiates pain centralization (C) from non-centralization (NC), which indicates good vs. poor prognostic validity respectively. The main aims were 1) to determine changes in Mechanical Diagnosis and Therapy (MDT) pain response classifications after transforaminal epidural steroid injections (TESIs) in candidates for lumbar herniated disc surgery and 2) to evaluate differences in short and long term outcomes for patients with different pain response classifications. Candidates for lumbar herniated disc surgery were assessed with a MDT protocol and their pain response classified as centralizing or peripheralizing. For this study,only patients were eligible who showed a peripheralizing pain response at intake. All patients then received TESIs and were reassessed and classified using the MDT protocol, into groups according to pain response (resolved, centralizing, peripheralizing with less pain and peripheralising with severe pain). After receiving targeted treatment based on pain response after TESIs, ranging from advice, MDT or surgery, follow-up assessments were completed at discharge and at 12 months. The primary outcomes were disability (Roland-Morris Disability Questionnaire [RMDQ] for Sciatica), pain severity in leg (visual analogue scale [VAS], 0-100) and global perceived effect (GPE). Linear mixed-models were used to determine between-groups differences in outcome. A total of 77 patients with lumbar disc herniation and peripheralizing symptoms were included. Patients received an average of 2 (SD 0.7) TESIs. After TESIs, 17 patients (22%) were classified as peripheralizing with continuing severe pain.These patients

    Steroid estrogens, such as estrone (E 1 ), 17β-estradiol (E 2 ), estriol (E 3 ), and 17α-ethinylestradiol (EE 2 ), are natural and synthetic hormones released into the environment through incomplete sewage discharge. This review focuses on the sources of steroid estrogens in wastewater treatment plants (WWTPs). The mechanisms and fate of steroid estrogens throughout the entire wastewater treatment system are also discussed, and relevant information on regulatory aspects is given. Municipal, pharmaceutical industry, and hospitals are the main sources of steroid estrogens that enter WWTPs. A typical WWTP comprises primary, secondary, and tertiary treatment units. Sorption and biodegradation are the main mechanisms for removal of steroid estrogens from WWTPs. The fate of steroid estrogens in WWTPs depends on the types of wastewater treatment systems. Steroid estrogens in the primary treatment unit are removed by sorption onto primary sludge, followed by sorption onto micro-flocs and biodegradation by microbes in the secondary treatment unit. Tertiary treatment employs nitrification, chlorination, or UV disinfection to improve the quality of the secondary effluent. Activated sludge treatment systems for steroid estrogens exhibit a removal efficiency of up to 100%, which is higher than that of the trickling filter treatment system (up to 75%). Moreover, the removal efficiency of advance treatment systems exceeds 90%. Regulatory aspects related to steroid estrogens are established, especially in the European Union. Japan is the only Asian country that implements a screening program and is actively involved in endocrine disruptor testing and assessment. This review improves our understanding of steroid estrogens in WWTPs, proposes main areas to be improved, and provides current knowledge on steroid estrogens in WWTPs for sustainable development.

    The short-term outcomes of vocal fold steroid injection (VFSI) are well documented. However, few studies have reported the long-term outcomes following VFSI. To investigate the incidence rates of symptom recurrence and secondary interventions following VFSI for benign vocal fold lesions. This prospective cohort study was conducted at a tertiary referral medical center in Taipei, Taiwan. The cohort included 189 patients with vocal fold lesions who had received VFSI as the primary treatment between August 2011 and September 2013. All participants underwent VFSI. Long-term surveillance was conducted through structured telephonic interviews and by reviewing medical charts every 6 months over a 2-year period. We assessed the 10-item voice handicap index, dysphonic symptoms, and whether the patients had received any additional interventions after the initial VFSI. The 189 participants (32 men and 157 women; mean [SD] age, 39 [10] years [range, 20-74 years] included patients who had undergone VFSI for vocal fold nodules (n = 72), polyps (n = 72), or mucus-retention cysts (n = 45). Following VFSI, 141 patients (74.6%; 23 men and 118 women; mean age, 39 years [range, 20-70 years]) showed positive response (ie, clinically significant symptom resolution without the need for additional procedures) and received long-term surveillance. The median follow-up period was 19.4 months, and 2 patients were lost to follow-up postoperatively within 1 year. The cumulative failure rates (subjective symptom recurrence plus secondary treatments) at 6, 12, 18, and 24 months after VFSI were 12%, 17%, 24%, and 32%, respectively. When the initial response rate to VFSI (141 of 189, 74.6%) was considered altogether, VFSI remained effective after 2 years in 50% of the initially recruited 189 patients. The highest rate of long-term effectiveness of VFSI occurred in vocal polyps (54%), followed by nodules (49%) and cysts (43%). This study demonstrates that VFSI can be beneficial in

  8. Effects of Sex Steroids on Fish Leukocytes

    Cabas, Isabel

    2018-01-01

    In vertebrates, in addition to their classically reproductive functions, steroids regulate the immune system. This action is possible mainly due to the presence of steroid receptors in the different immune cell types. Much evidence suggests that the immune system of fish is vulnerable to xenosteroids, which are ubiquitous in the aquatic environment. In vivo and in vitro assays have amply demonstrated that oestrogens interfere with both the innate and the adaptive immune system of fish by regulating the main leukocyte activities and transcriptional genes. They activate nuclear oestrogen receptors and/or G-protein coupled oestrogen receptor. Less understood is the role of androgens in the immune system, mainly due to the complexity of the transcriptional regulation of androgen receptors in fish. The aim of this manuscript is to review our present knowledge concerning the effect of sex steroid hormones and the presence of their receptors on fish leukocytes, taking into consideration that the studies performed vary as regard the fish species, doses, exposure protocols and hormones used. Moreover, we also include evidence of the probable role of progestins in the regulation of the immune system of fish. PMID:29315244

    Corticosteroids used as immunosuppressants to prevent acute rejection (AR) and graft loss (GL) following kidney transplantation are associated with serious cardiovascular and other adverse events. Evidence from short-term randomized controlled trials suggests that many patients on a tacrolimus-based immunosuppressant regimen can withdraw from steroids without increased AR or GL risk. To measure the long-term tradeoff between GL and adverse events for a heterogeneous-risk population and determine the optimal timing of steroid withdrawal. A discrete event simulation was developed including, as events, AR, GL, myocardial infarction (MI), stroke, cytomegalovirus, and new onset diabetes mellitus (NODM), among others. Data from the United States Renal Data System were used to estimate event-specific parametric regressions, which accounted for steroid-sparing regimen (avoidance, early 7-d withdrawal, 6-mo withdrawal, 12-mo withdrawal, and maintenance) as well as patients' demographics, immunologic risks, and comorbidities. Regression-equation results were used to derive individual time-to-event Weibull distributions, used, in turn, to simulate the course of patients over 20 y. Patients on steroid avoidance or an early-withdrawal regimen were more likely to experience AR (45.9% to 55.0% v. 33.6%, P < 0.05) and GL (51.5% to 68.8% v. 37.8%, P < 0.05) compared to patients on steroid maintenance. Patients in 6-mo and 12-mo steroid withdrawal groups were less likely to experience MI (11.1% v. 13.3%, P < 0.05), NODM (30.7% to 34.4% v. 37.7%, P < 0.05), and cardiac death (29.9% to 30.5% v. 32.4%, P < 0.05), compared to steroid maintenance. Strategies of 6- and 12-mo steroid withdrawal post-kidney transplantation are expected to reduce the rates of adverse cardiovascular events and other outcomes with no worsening of AR or GL rates compared with steroid maintenance.

    The illicit use of anabolic steroids among the gym population continues to rise, along with the number of steroid using clients attending harm reduction services in the UK. This presents serious challenges to public health. Study objectives were to account for the experiences of anabolic steroid users and investigate how 'risk environments' produce harm. Qualitative face-to-face interviews with 24 users of anabolic steroids engaged with harm reduction services in the UK. Body satisfaction was an important factor when deciding to start the use of anabolic steroids. Many users were unaware of the potential dangers of using drugs from the illicit market, whereas some had adopted a range of strategies to negotiate the hazards relating to the use of adulterated products, including self-experimentation to gauge the perceived efficacy and unwanted effects of these drugs. Viewpoints, first-hand anecdotes, norms and practices among groups of steroid users created boundaries of 'sensible' drug use, but also promoted practices that may increase the chance of harms occurring. Established users encouraged young users to go to harm reduction services but, at the same time, promoted risky injecting practices in the belief that this would enhance the efficacy of anabolic steroids. Current steroid-related viewpoints and practices contribute to the risk environment surrounding the use of these drugs and may undermine the goal of current public health strategies including harm reduction interventions. The level of harms among anabolic steroid users are determined by multiple and intertwining factors, in addition to the harms caused by the pharmacological action or injury and illness associated with incorrect injecting techniques.

    The method of high sensitive gas chromatographic/time-of-flight mass-spectrometric (GC/TOF-MS) analysis of steroids was developed. Low-resolution TOF-MS instrument (with fast spectral acquisition rate) was used. This method is based on the formation of the silyl derivatives of steroids; exchange of the reagent mixture (pyridine and N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA)) for tert-butylmethylether; offline large sample volume injection of this solution based on sorption concentration of the respective derivatives from the vapour-gas mixture flow formed from the solution and inert gas flows; and entire analytes solvent-free concentrate transfer into the injector of the gas chromatograph. Detection limits for 100 µl sample solution volume were 0.5-2 pg/µl (depending on the component). Application of TOF-MS model 'TruTOF' (Leco, St Joseph, MO, USA) coupled with gas chromatograph and ChromaTOF software (Leco, St Joseph, MO, USA) allowed extraction of the full mass spectra and resolving coeluted peaks. Due to use of the proposed method (10 µl sample aliquot) and GC/TOF-MS, two times more steroid-like compounds were registered in the urine extract in comparison with the injection of 1 µl of the same sample solution.

    Objective To determine the rate of vasovagal (vv) complications in fluoroscopically guided interventional procedures. Design Retrospective case series analysis of prospectively collected data from March 8, 2004 to January 30, 2009. Setting A single academic medical center. Subjects Four thousand one hundred eighty-three subjects undergoing 8,010 consecutive injections. Outcome Measures Pearson's chi-square test was used to determine the relationship between categorical variables. Results A total of 8,010 injections, including epidural steroid injections, radiofrequency nerve ablations, medial branch blocks, hip injections, knee injections, and glenohumeral injections were performed. Overall vv reaction rate was 2.6%, with 0.8% of procedures resulting in early terminated due to vv reaction. Peripheral joint injections had a vv rate of 0.2%, all occurring in hip injections. Transforaminal epidural steroid injections had a vv rate of 3.5%. Diagnostic blocks of the medial branches had the highest rate of vv (5.1%). Other predictors of vv reactions were identified including preprocedure pain score visual analog scale <5 (P = 0.004), male gender (P < 0.001), and age less than 65 years old (P < 0.001). Conclusions vv reactions have an overall low occurrence rate (2.6%) in interventional procedures ranging from 0% in peripheral knee and shoulder injections to 5.1% in medial branch blocks. Conservative treatment of vv reaction and willingness to terminate procedures resulted in no serious adverse events related to vv reaction in 8,010 procedures. PMID:24118835

Forty-seven patients with Dupuytren disease who were candidates for PNA (at least 1 contracture of at least 20°) participated in the study. Patients were randomized either to receive TA injections immediately following and 6 weeks and 3 months after the procedure or to receive no injections. Injections were administered into cords. The number of injections and the amount of TA per injection was determined based on the number of digits involved and the cord size. All subjects returned for 3 follow-up visits after the procedure, and contractures were measured using a goniometer. Change in total active extension deficit (TAED) was analyzed using a repeated measures analysis of variance to assess for differences between groups, time points, and interaction between group and time point. Descriptive statistics were calculated for all variables of interest. Continuous measures were summarized using means and standard deviations. There was no significant difference in TAED between groups before cord aponeurotomy. Correction at 6 months was 87% of preoperative TAED for the TA group versus 64% for the control group. This difference was statistically significant. The amount of TA administered did not correlate with TAED improvement. The study group who received TA in combination with PNA experienced a significantly greater degree of correction of flexion deformity at 6 months than those who had PNA alone.

    The aim of this study was to illustrate the risk of vocal fold atrophy in patients who receive serial subepithelial steroid injections for vocal fold scar. This study is a retrospective case report of two patients who underwent a series of weekly subepithelial infusions of 10 mg/mL dexamethasone for benign vocal fold lesion. Shortly after the procedures, both patients developed a weak and breathy voice. The first patient was a 53-year-old man with radiation-induced vocal fold stiffness. Six injections were performed unilaterally, and 1 week later, he developed unilateral vocal fold atrophy with new glottal insufficiency. The second patient was a 67-year-old woman with severe vocal fold inflammation related to laryngitis and calcinosis, Raynaud's phenomenon, esophagean dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome. Five injections were performed bilaterally, and 1 week later, she developed bilateral vocal fold atrophy with a large midline glottal gap during phonation. In both cases, the steroid-induced vocal atrophy resolved spontaneously after 4 months. Serial subepithelial steroid infusions of the vocal folds, although safe in the majority of patients, carry the risk of causing temporary vocal fold atrophy when given at short intervals.

    To determine if a mail reminder system leads to an increase in the percentage of depot medroxyprogesterone acetate (Depo-Provera) injections administered on time, the charts of 184 women were reviewed. The reminder postcard included the due dates of both the next medroxyprogesterone injection and the next Papanicolaou test. Timeliness of injections improved with the reminder system from 64% administered on time to 76% (P < .02). Injections given late despite the reminders were late a mean of 8 days. Injections given late before the reminder system began were late a mean of 20 days (P < .05). If injections given during the injection's 14-day "grace" period are included, the on-time rate improved from 87% to 96% with the reminder system (P < .005). The reminder system was not effective in ensuring annual Papanicolaou testing. Vigilance is needed to ensure that women receiving medroxyprogesterone injections also receive timely Papanicolaou testing.

    The purpose of this study was to compare the outcome of percutaneous curettage with intralesional injection of methylprednisolone and bone marrow for unicameral bone cysts (UBCs). This was a retrospective review of 46 children and adolescents with UBC treated with autologous bone marrow injection, methylprednisolone acetate injection or percutaneous curettage alone. Inclusion criteria were a radiological diagnosis of UBC and at least 24 months follow-up from the last procedure. Healing was determined using Neer/Cole 4-grades rating scale. The 3 treatment groups were comparable with regard to age, sex, location of the cyst, and the number of procedures undertaken. At 2 years follow-up, the proportion of patients with satisfactory healing (Neer/Cole grades I and II) was greatest among those who underwent percutaneous curettage (70%) compared with bone marrow injection (21%) and methylprednisolone acetate injection (41%) (P = 0.03). We found no association between healing and age (P = 0.80) nor between healing and sex (P = 0.61). These results suggest that mechanical disruption of the cyst membrane may be helpful in healing of cysts and that this technique may be preferred to simple intralesional injections. Level III.

    To illustrate whether the steroid-antivirals treatment could acquire a better recovery in patients with Bell's palsy than the steroids alone treatment. We conducted an exhaustive search over Pub med/Medline, Ovid, Elsevier search engines and the Cochrane library thereby collecting the randomized controlled trials in the treatment of patients with Bell's palsy with steroid-antivirals and steroids. The qualities of relevant articles were assessed by GRADE, which was used to present the overall quality of evidence as recommended by the Cochrane Handbook for Systematic Reviews of Interventions. Two investigators evaluated these papers independently, and resolved the disagreements by discussion. At last 8 eligible papers (1816 patients included: 896 treated with steroid-antivirals and 920 treated with steroids alone) match the criteria. Owing to the result (chi(2) = 12.57, P = 0.08, I(2) = 44%) presented by the formal test for heterogeneity, the fixed effect meta-analysis model was chosen. The facial muscle recovery between the steroids-antivirals group and the steroids alone group show significant differences (OR = 1.52, 95% CI: 1.20-1.94), while the statistical outcome of adverse effect shows no statistical significance (OR = 1.28, 95% CI: 0.71-2.31). The present meta-analysis indicates that the steroid-antivirals treatment could improve the recovery rate in patients with Bell's palsy when comparing with the steroid alone treatment. This meta-analysis showed that the steroid-antivirals treatment achieved the better outcomes in patients with Bell's palsy. Clinicians should consider that steroid-antivirals therapy is an alternative choice for the patients with Bell's palsy.

    Study Design: A randomized, double-blind, active controlled trial. Objective: To evaluate the effectiveness of cervical interlaminar epidural injections of local anesthetic with or without steroids in the management of chronic neck pain and upper extremity pain in patients with disc herniation and radiculitis. Summary of Background Data: Epidural injections in managing chronic neck and upper extremity pain are commonly employed interventions. However, their long-term effectiveness, indications, and medical necessity, of their use and their role in various pathologies responsible for persistent neck and upper extremity pain continue to be debated, even though, neck and upper extremity pain secondary to disc herniation and radiculitis, is described as the common indication. There is also paucity of high quality literature. Methods: One-hundred twenty patients were randomly assigned to one of 2 groups: Group I patients received cervical interlaminar epidural injections of local anesthetic (lidocaine 0.5%, 5 mL); Group II patients received 0.5% lidocaine, 4 mL, mixed with 1 mL of nonparticulate betamethasone. Primary outcome measure was ≥ 50 improvement in pain and function. Outcome assessments included Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), opioid intake, employment, and changes in weight. Results: Significant pain relief and functional status improvement (≥ 50%) was demonstrated in 72% of patients who received local anesthetic only and 68% who received local anesthetic and steroids. In the successful group of participants, significant improvement was illustrated in 77% in local anesthetic group and 82% in local anesthetic with steroid group. Conclusions: Cervical interlaminar epidural injections with or without steroids may provide significant improvement in pain and function for patients with cervical disc herniation and radiculitis.

    The purpose of this study was to evaluate the effects of intra-articular temporomandibular joint (TMJ) treatment in patients with juvenile idiopathic arthritis (JIA). The inclusion criteria were met by 21 patients (38 joints). Joints were randomly selected for either arthrocentesis alone (n=17) or arthrocentesis with the additional use of triamcinolone hexacetonide (n=21) using a closed single-needle system. Measurements of pain and function were performed at baseline and at follow-up after 3 and 8 months. Pain on opening and lateral excursion improved significantly after injections. Pain decreased significantly from baseline to first and second control on a visual analogue scale (VAS) for overall pain (49-18-8) and overall function (41-19-4). Significant improvement was recorded for pain on palpation of muscles and joints. There was no statistically significant difference between the treatment modalities, with or without glucocorticoid injection. Arthrocentesis in the TMJ treatment of patients with JIA may be beneficial and steroids had no additional effect. Further studies are needed to evaluate the long-term effects on the TMJ structures and on condylar growth from arthrocentesis and intra-articular steroid injections.

  2. Rapid steroid influences on visually guided sexual behavior in male goldfish

    2013-01-01

    The ability of steroid hormones to rapidly influence cell physiology through nongenomic mechanisms raises the possibility that these molecules may play a role in the dynamic regulation of social behavior, particularly in species in which social stimuli can rapidly influence circulating steroid levels. We therefore tested if testosterone (T), which increases in male goldfish in response to sexual stimuli, can rapidly influence approach responses towards females. Injections of T stimulated approach responses towards the visual cues of females 30–45 min after the injection but did not stimulate approach responses towards stimulus males or affect general activity, indicating that the effect is stimulus-specific and not a secondary consequence of increased arousal. Estradiol produced the same effect 30–45 min and even 10–25 min after administration, and treatment with the aromatase inhibitor fadrozole blocked exogenous T’s behavioral effect, indicating that T’s rapid stimulation of visual approach responses depends on aromatization. We suggest that T surges induced by sexual stimuli, including preovulatory pheromones, rapidly prime males to mate by increasing sensitivity within visual pathways that guide approach responses towards females and/or by increasing the motivation to approach potential mates through actions within traditional limbic circuits.

    Free and conjugated steroids coexist in a dynamic equilibrium due to complex biosynthetic and metabolic processes. This may have clinical significance related to various physiological conditions, including sex development involving the reproductive system. Therefore, we performed quantitative profiling of 16 serum steroids conjugated with glucuronic and sulfuric acids using liquid chromatography-mass spectrometry (LC-MS). All steroid conjugates were purified by solid-phase extraction and then separated through a 3-μm particle size C18 column (150mm×2.1mm) at a flow rate of 0.3 mL/min in the negative ionization mode. The LC-MS-based analysis was found to be linear (r(2)>0.99), and all steroid conjugates had a limit-of-quantification (LOQ) of 10ng/mL, except for cholesterol sulfate and 17β-estradiol-3,17-disulfate (20ng/mL). The extraction recoveries of all steroid conjugates ranged from 97.9% to 110.7%, while the overall precision (% CV) and accuracy (% bias) ranged from 4.8% to 10.9% and from 94.4% to 112.9% at four different concentrations, respectively. Profiling of steroid conjugates corrected by adiposity revealed decreased levels of steroid sulfates (P<0.01) in overweight and obese girls compared to normal girls. The suggested technique can be used for evaluating metabolic changes in steroid conjugates and for understanding the pathophysiology and relative contributions of adiposity in childhood obesity.

  5. Steroid and sterol 7-hydroxylation: ancient pathways.

    PubMed

    Lathe, Richard

    2002-11-01

    B-ring hydroxylation is a major metabolic pathway for cholesterols and some steroids. In liver, 7 alpha-hydroxylation of cholesterols, mediated by CYP7A and CYP39A1, is the rate-limiting step of bile acid synthesis and metabolic elimination. In brain and other tissues, both sterols and some steroids including dehydroepiandrosterone (DHEA) are prominently 7 alpha-hydroxylated by CYP7B. The function of extra-hepatic steroid and sterol 7-hydroxylation is unknown. Nevertheless, 7-oxygenated cholesterols are potent regulators of cell proliferation and apoptosis; 7-oxygenated derivatives of DHEA, pregnenolone, and androstenediol can have major effects in the brain and in the immune system. The receptor targets involved remain obscure. It is argued that B-ring modification predated steroid evolution: non-enzymatic oxidation of membrane sterols primarily results in 7-oxygenation. Such molecules may have provided early growth and stress signals; a relic may be found in hydroxylation at the symmetrical 11-position of glucocorticoids. Early receptor targets probably included intracellular sterol sites, some modern steroids may continue to act at these targets. 7-Hydroxylation of DHEA may reflect conservation of an early signaling pathway.

    This review aims to evaluate the role of anaesthetics, steroids and platelet-rich plasma (PRP) employed with ultrasound-guided injection in the management of musculoskeletal pathology of the extremities. Ultrasound-guided injection represents an interesting and minimally invasive solution for the treatment of tendon and joint inflammatory or degenerative diseases. The availability of a variety of new drugs such as hyaluronic acid and PRP provides expansion of the indications and therapeutic possibilities. The clinical results obtained in terms of pain reduction and functional recovery suggest that the use of infiltrative procedures can be a good therapeutic alternative in degenerative and inflammatory joint diseases.

    This study aimed to determine the factors associated with response to intra-articular steroid injection (IASI) in patients with knee joint osteoarthritis. One hundred seventy-four female patients, age ranging from 30 to 80 years, diagnosed to have osteoarthritis of the knee joint, were given IASI. Response to IASI was assessed by using WOMAC and VAS at 2 weeks, 4 weeks and 3 months. At 3 months, the subjects were categorized as responders, partial responders and non-responders to treatment by IASI. Various factors were narrowed down to see their effect on response, namely age, BMI, smoking habits, comorbidities, presence of clinical effusion, radiographic score, local knee tenderness, range of movement and socioeconomic status. One hundred twenty-four patients completed the study. 16.1 % showed 50 % or more improvement in WOMAC score at 3 months post IASI therapy, whereas 38.7 % of OA patients had more than 50 % improvement in VAS score. Out of all factors, range of movement, local knee tenderness and radiographic score of the affected joint are the three parameters which can predict the improvement in WOMAC score after 3 months of IASI therapy (P = 0.013, P = 0.045 and P = 0.000, respectively). Age of the patient can predict improvement in VAS at 3 months post IASI (P = 0.027). We conclude that age, range of movement, local knee tenderness and radiographic score of the affected joint can predict response to IASI after 3 months of IASI therapy.

    The plastic industry is a very important manufacturing sector and injection molding is a widely used forming method in that industry. The contribution of this work is the development of a strategy to retrofit control of an injection molding machine based on an embedded system microprocessors sensor network on a field programmable gate array (FPGA) device. Six types of embedded processors are included in the system: a smart-sensor processor, a micro fuzzy logic controller, a programmable logic controller, a system manager, an IO processor and a communication processor. Temperature, pressure and position are controlled by the proposed system and experimentation results show its feasibility and robustness. As validation of the present work, a particular sample was successfully injected. PMID:23202036

    Of children with idiopathic nephrotic syndrome, 10%–20% fail to respond to steroids or develop secondary steroid resistance (termed initial steroid sensitivity) and the majority progress to transplantation. Although 30%–50% of these patients suffer disease recurrence after transplantation, with poor long-term outcome, no reliable indicator of recurrence has yet been identified. Notably, the incidence of recurrence after transplantation appears reduced in patients with steroid-resistant nephrotic syndrome (SRNS) due to monogenic disorders. We reviewed 150 transplanted patients with SRNS to identify biomarkers that consistently predict outcome of SRNS after transplantation. In all, 25 children had genetic or familial SRNS and did not experience post-transplant recurrence. We reviewed phenotypic factors, including initial steroid sensitivity, donor type, age, ethnicity, time to ESRD, and time on dialysis, in the remaining 125 children. Of these patients, 57 (45.6%) developed post-transplant recurrence; 26 of 28 (92.9%) patients with initial steroid sensitivity recurred after transplantation, whereas only 26 of 86 (30.2%) patients resistant from the outset recurred (odds ratio, 30; 95% confidence interval, 6.62 to 135.86; P<0.001). We were unable to determine recurrence in two patients (one with initial steroid sensitivity), and nine patients did not receive initial steroids. Our data show that initial steroid sensitivity is highly predictive of post-transplant disease recurrence in this pediatric patient population. Because a pathogenic circulating permeability factor in nephrotic syndrome remains to be confirmed, we propose initial steroid sensitivity as a surrogate marker for post-transplant recurrence.

    To realize site-specific and variable-rate application of agricultural pesticides, accurately metering and controlling the chemical injection rate is necessary. This study presents a prototype of a direct nozzle injection system (DNIS) by which chemical concentration transport lag was greatly reduced. In this system, a rapid-reacting solenoid valve (RRV) was utilized for injecting chemicals, driven by a pulse-width modulation (PWM) signal at 100 Hz, so with varying pulse width the chemical injection rate could be adjusted. Meanwhile, a closed-loop control strategy, proportional-integral-derivative (PID) method, was applied for metering and stabilizing the chemical injection rate. In order to measure chemical flow rates and input them into the controller as a feedback in real-time, a thermodynamic flowmeter that was independent of chemical viscosity was used. Laboratory tests were conducted to assess the performance of DNIS and PID control strategy. Due to the nonlinear input-output characteristics of the RRV, a two-phase PID control process obtained better effects as compared with single PID control strategy. Test results also indicated that the set-point chemical flow rate could be achieved within less than 4 s, and the output stability was improved compared to the case without control strategy.

    The detection of the abuse of anabolic steroids in equine sport is complicated by the endogenous nature of some of the abused steroids, such as testosterone and nandrolone. These steroids are commonly administered as intramuscular injections of esterified forms of the steroid, which prolongs their effects and improves bioavailability over oral dosing. The successful detection of an intact anabolic steroid ester therefore provides unequivocal proof of an illegal administration, as esterified forms are not found endogenously. Detection of intact anabolic steroid esters is possible in plasma samples but not, to date, in the traditional doping control matrix of urine. The analysis of equine mane hair for the detection of anabolic steroid esters has the potential to greatly extend the time period over which detection of abuse can be monitored. Equine mane hair samples were incubated in 0.1M phosphate buffer (pH 9.5) before anabolic steroids (testosterone, nandrolone, boldenone, trenbolone and stanozolol), anabolic steroid esters (esters of testosterone, nandrolone, boldenone and trenbolone) and associated compounds (fluticasone propionate and esters of hydroxyprogesterone) were extracted by liquid-liquid extraction with a mix of hexane and ethyl acetate (7:3, v:v). Further sample clean up by solid phase extraction was followed by derivatisation with methoxylamine HCL and analysis by UHPLC-MS/MS. Initial method development was performed on a representative suite of four testosterone esters (propionate, phenylpropionate, isocaproate and decanoate) and the method was later extended to include a further 18 compounds. The applicability of the method was demonstrated by the analysis of mane hair samples collected following the intramuscular administration of 500 mg of Durateston(®) (mixed testosterone esters) to a Thoroughbred mare (560 kg). The method was subsequently used to successfully detect boldenone undecylenate and stanozolol in hair samples collected following

  13. Steroid dysregulation and stomatodynia (burning mouth syndrome).

    PubMed

    Woda, Alain; Dao, Thuan; Gremeau-Richard, Christelle

    2009-01-01

    Stomatodynia ( burning mouth syndrome) is characterized by a spontaneous, continuous burning pain felt in the oral mucosa typically of anxiodepressive menopausal women. Because there is no obvious organic cause, it is considered a nonspecific pain. This Focus Article proposes a hypothesis based on the following pathophysiological cascade: chronic anxiety or post traumatic stress leads to a dysregulation of the adrenal production of steroids. One consequence is a decreased or modified production of some major precursors for the neuroactive steroid synthesis occurring in the skin, mucosa, and nervous system. At menopause, the drastic fall of the other main precursor supply , the gonadal steroids, leads to a brisk alteration of the production of neuroactive steroids. This results in neurodegenerative alterations of small nerves fibers of the oral mucosa and /or some brain areas involved in oral somatic sensations. These neuropathic changes become irreversible and precipitate the burning pain, dysgeusia, and xerostomia associated with stomatodynia, which all involve thin nerve fibers.

    Sex steroids are essential for reproduction and development in animals and humans, and sex steroids also play an important role in neuroprotection following brain injury. New data indicate that sex-specific responses to brain injury occur at the cellular and molecular levels. This review summarizes the current understanding of neuroprotection by sex steroids, particularly estrogen, androgen, and progesterone, based on both in vitro and in vivo studies. Better understanding of the role of sex steroids under physiological and pathological conditions will help us to develop novel effective therapeutic strategies for brain injury. PMID:20595940

Painting bumper magnets are used for both horizontal and vertical phase space painting. Closed-orbit bumper magnets are used for facilitating the installation of the injection septa and decreasing proton traversal in the stripping foil. Even with large beam emittance of about 300 {pi}mm.mrad used, BSNS/RCS still approaches the space charge limit during the injection/trapping phase for the accumulated particles of 1.9*10{sup 13} and at the low injection energy of 80 MeV.

    In April 2014, the Food and Drug Administration (FDA) issued a Drug Safety Communication requesting that corticosteroid labeling include warnings that injection of corticosteroids into the epidural space of the spine may result in rare but serious adverse events, including loss of vision, stroke, paralysis, and death. The International Spine Intervention Society spearheaded a collaboration of more than a dozen other medical societies in submitting the letter below to the FDA on November 7, 2014. We are publishing the letter to ensure that the readership of Pain Medicine is aware of the multisociety support for the safety and effectiveness of these procedures.

    Polycystic ovary syndrome is a heterogeneous endocrine disorder that affects reproductive-age women. The mechanisms underlying the endocrine heterogeneity and neuroendocrinology of polycystic ovary syndrome are still unclear. In this study, we investigated the expression of the kisspeptin system and gonadotropin-releasing hormone pulse regulators in the hypothalamus as well as factors related to luteinizing hormone secretion in the pituitary of polycystic ovary syndrome rat models induced by testosterone or estradiol. A single injection of testosterone propionate (1.25 mg) (n=10) or estradiol benzoate (0.5 mg) (n=10) was administered to female rats at 2 days of age to induce experimental polycystic ovary syndrome. Controls were injected with a vehicle (n=10). Animals were euthanized at 90-94 days of age, and the hypothalamus and pituitary gland were used for gene expression analysis. Rats exposed to testosterone exhibited increased transcriptional expression of the androgen receptor and estrogen receptor-β and reduced expression of kisspeptin in the hypothalamus. However, rats exposed to estradiol did not show any significant changes in hormone levels relative to controls but exhibited hypothalamic downregulation of kisspeptin, tachykinin 3 and estrogen receptor-α genes and upregulation of the gene that encodes the kisspeptin receptor. Testosterone- and estradiol-exposed rats with different endocrine phenotypes showed differential transcriptional expression of members of the kisspeptin system and sex steroid receptors in the hypothalamus. These differences might account for the different endocrine phenotypes found in testosterone- and estradiol-induced polycystic ovary syndrome rats.

    In the present study, we have investigated the sex steroid hormone levels, oocyte maturation and spawning performance in Waigieu seaperch (Psammoperca waigiensis) exposed to different doses (0, (control), 0.05, 0.25 and 0.5 mg/kg fish) of thyroxin (T(4)) both through diet (continuously) and injection (single injection). In addition, we also studied plasma steroid hormone levels and spawning performances in female fish injected with a single dose of D-Ala(6), Pro(9)-Net-mGnRH (LHRHa: 50 microg/kg), human chronic gonadotropin (HCG: 1,500 IU/kg) and carp pituitary extract (CPE: 10 mg/kg). In all experiments, samples were collected at 0, 6, 12, 24 and 48 h after exposure. T4 exposure via dietary route produced differential and enhanced effects, compared with when the compound was injected to the broodstock. A significant association between exposure to dietary T4, elevated plasma steroid hormone levels, maturation-, spawning-, fertilization- and hatching rate, egg diameter, embryogenesis and larval growth were observed. Interestingly, we observed that broodstock groups fed with T4 doses spawned 20 days earlier than the control group. Thus, we propose that these differences may be attributed to higher systemic availability of T4 due to dietary exposure that is easily transferable to eggs and embryos, as opposed to injection that require absorption to increase bioavailability. Furthermore, our results show that LHRHa, CPE and HCG produced significant increase in spawning rate, but significantly reduced fertilization- and hatching rates. Waigieu seaperch is a new candidate for marine aquaculture in Vietnam and relatively little is known about the reproductive biology and endocrinology of this species. Therefore, the present study forms an integral basis for understanding the reproductive endocrinology of a tropical marine finfish with increasing aquaculture prospects and may also contribute in the development of sustainable aquaculture of this species in a developing

    In support of the Carbon dioxide And Moisture Removal Amine Swing-bed (CAMRAS) testing, a contaminant injection system as well as a contaminant monitoring system has been developed by the Johnson Space Center Air Revitalization Systems (JSC-ARS) team. The contaminant injection system has been designed to provide trace level concentrations of contaminants generated by humans in a closed environment during space flight missions. The contaminant injection system continuously injects contaminants from three gas cylinders, two liquid reservoirs and three permeation ovens. The contaminant monitoring system has been designed to provide real time gas analysis with accurate flow, humidity and gas concentration measurements for collection during test. The contaminant monitoring system consists of an analytical real time gas analyzer, a carbon monoxide sensor, and an analyzer for ammonia and water vapor.

    To explore possible changes in adrenal steroid metabolism and androgenic-anabolic status in female endurance athletes as a mechanism for their hypercortisolism. Adrenal steroids and androgenic-anabolic factors were studied during basal conditions and in response to ACTH stimulation related to menstrual status. Department of Obstetrics and Gynecology, Karolinska Hospital, Stockholm, Sweden. Thirteen female elite middle to long distance runners (six eumenorrheic, seven oligoamenorrheic) and seven regularly menstruating controls. Blood samples were collected before and after an injection of 250 micrograms IV synthetic ACTH 1-24. Body weight, height, and body fat were measured. Basal serum concentrations of cortisol, androstenedione (A), DHEA, DHEAS, 17 alpha-hydroxyprogesterone (17-OHP), T, steroid-binding proteins, and insulin-like growth factor I and ACTH-induced response (area under the curve) of cortisol, DHEA, and 17-OHP. Oligoamenorrheic athletes had higher basal cortisol and A concentrations compared with healthy controls, whereas basal levels of DHEA and DHEAS were normal. Important findings in the oligoamenorrheic athletes were a significantly lower ratio between the ACTH-induced increments of DHEA and 17-OHP and an increased ratio between basal A and DHEAS. Insulin-like growth factor I was correlated negatively to sex hormone-binding globulin and to the amount of body fat in the combined material. The results indicate a redistribution of adrenal steroid metabolism in favor of glucocorticoid production in female endurance athletes. We suggest that hypercortisolism in female endurance athletes is a physiological adaptation to maintain adequate blood glucose levels during a condition of energy deficiency.

    Cervical interlaminar epidural steroid injections (ESIs) are commonly performed as one part of a multi-modal analgesic regimen in the management of upper extremity radicular pain. Spinal epidural hematoma (SEH) is a rare complication with a reported incidence ranging from 1.38 in 10,000 to 1 in 190,000 epidurals. Current American Society of Regional Anesthesia (ASRA), American Society of Interventional Pain Physicians (ASIPP), and the International Spine Intervention Society (ISIS) recommendations are that non-steroidal anti-inflammatory drugs (NSAIDs) do not need to be withheld prior to epidural anesthesia. We report a case wherein intramuscular ketorolac and oral fluoxetine contributed to a SEH and tetraplegia following a cervical interlaminar (ESI). A 66 year-old woman with chronic renal insufficiency and neck pain radiating into her right upper extremity presented for evaluation and was deemed an appropriate CESI candidate. Cervical magnetic resonance imaging (MRI) revealed multi-level neuroforaminal stenosis and degenerative intervertebral discs. Utilizing a loss of resistance to saline technique, an 18-gauge Tuohy-type needle entered the epidural space at C6-7. After negative aspiration, 4 mL of saline with 80 mg of methyl-prednisolone was injected. Immediately thereafter, the patient reported significant spasmodic-type localized neck pain with no neurologic status changes. A decision was made to administer 30 mg intramuscular ketorolac as treatment for the spasmodic-type pain. En route home, she developed a sudden onset of acute tetraplegia. She was brought to the emergency department for evaluation including platelet and coagulation studies which were normal. MRI demonstrated an epidural hematoma extending from C5 to T7. She underwent a bilateral C5-T6 laminectomy with epidural hematoma evacuation and was discharged to an acute inpatient rehabilitation hospital. Chronic renal insufficiency, spinal stenosis, female gender, and increasing age have been

    Several factors influencing the carbon isotope ratios (CIR) of endogenous urinary steroids have been identified in recent years. One of these should be the metabolism of steroids inside the body involving numerous different enzymes. A detailed look at this metabolism taking into account differences found between steroids excreted as glucuronides or as sulphates and hydrogen isotope ratios of different steroids pointed out possibility of unequal CIR at the main production sites inside the male body - the testes and the adrenal glands. By administration of β-HCG it is possible to strongly stimulate the steroid production within the testes without influencing the production at the adrenal glands. Therefore, this treatment should result in changed CIR of urinary androgens in contrast to the undisturbed pre-treatment values. Four male volunteers received three injections of β-HCG over a time course of 5 days and collected their urine samples at defined intervals after the last administration. Those samples showing the largest response in contrast to the pre-administration urines were identified by steroid profile measurements and subsequent analysed by GC/C/IRMS. CIR of androsterone, etiocholanolone, testosterone, 5α- and 5β-androstanediol and pregnanediol were compared. While pregnanediol was not influenced, most of the investigated androgens showed depleted values after treatment. The majority of differences were found to be statistically significant and nearly all showed the expected trend towards more depleted δ(13)C-values. These results support the hypothesis of different CIR at different production sites inside the human body. The impact of these findings on doping control analysis will be discussed.

    A simulation model of an electronically controlled two solenoid valve fuel injection system for a diesel engine is established in the AMESim environment. The accuracy of the model is validated through comparison with experimental data. The influence of pre-injection control parameters on main-injection quantity under different control modes is analyzed. In the spill control valve mode, main-injection fuel quantity decreases gradually and then reaches a stable level because of the increase in multi-injection dwell time. In the needle control valve mode, main-injection fuel quantity increases with rising multi-injection dwell time; this effect becomes more obvious at high-speed revolutions and large main-injection pulse widths. Pre-injection pulse width has no obvious influence on main-injection quantity under the two control modes; the variation in main-injection quantity is in the range of 1 mm3.

    Objectives/Hypothesis To describe the presentation, stenosis characteristics, etiological differences, and outcomes of adult laryngotracheal stenosis treated with endoscopic cold incision, balloon dilation, topical mitomycin C application, and steroid injection. Study Design Retrospective chart review. Methods Demographic and clinical data were extracted for patients treated between March 2000 and December 2010. Prolonged intubation and idiopathic patient data were utilized for comparative analysis. Results Eighty patients (65 females; 15 males; 220 procedures; 2.9 years mean follow-up) presented with dyspnea (81%) and/or exercise intolerance (40%). Most commonly, etiologies were idiopathic (53 of 80; 66%) or prolonged intubation (14 of 80; 18%). Mean procedures per patient and interval between procedures were 2.8 procedures and 405 days, respectively. Mean stenosis length and distance from the caudal phonating edge of the true vocal folds were 9 mm and 19 mm. Complication, tracheotomy, and open-procedure rates were 1.8%, 1.4%, and 10.0%, respectively. Patients with more than two procedures demonstrated a mean 4-mm reduction in stenosis length and a 2-mm cephalad progression of stenosis over time. More caudal stenoses required more frequent procedures. Procedures were less frequent as more procedures were performed. Stenosis characteristics, interval between procedures, and total procedures were similar between idiopathic patients with or without intubation histories, but different between idiopathic and prolonged intubation patients. Conclusions This procedure was shown to be a viable option in adult laryngotracheal stenosis. Repeat dilation was likely, but was performed without adversely affecting stenosis characteristics. Stenoses farther from the vocal folds required procedures more frequently. Idiopathic patients with a history of brief, elective intubation had stenosis characteristics and responses to therapy similar to idiopathic patients without an

    : Millions of men use androgenic-anabolic steroids (AAS) to stimulate muscle growth and improve physical appearance. Although 1 out of 3 people who uses androgenic-anabolic steroids develops a steroid use disorder, the effects of the drugs on the central nervous system and the psyche are still not well understood. Although most addictive substances improve mood immediately after administration, AAS exert less pronounced euphoric effects. Instead, they are primarily taken for the delayed gratification of increased muscle mass. Withdrawal from AAS may lead to a range of somatic and psychiatric symptoms, and, in many cases, comprehensive treatment supervised by an endocrinologist and a psychiatrist is required.

    Objective: To investigate the efficacy of corticosteroid injections into the carpometacarpal joint of the thumb (CMCJ) in patients with osteoarthritis. Design: A double blind, randomised controlled trial using 40 hospital referred patients with CMCJ osteoarthritis who received intra-articular injections of 5 mg triamcinolone hexacetonide (0.25 ml) or sterile 0.9% saline (0.25 ml). Injections were given under imaging control. Main outcome measures: The primary outcome was improvement in a pain visual analogue score (VAS) of 20% at 24 weeks. In addition patients were assessed at 4, 12, and 24 weeks for joint stiffness, joint tenderness, and physician and patient global assessments. Hand radiographs were evaluated for the degree of CMC joint space narrowing and marginal osteophytes according to the OARSI atlas. Results: Baseline clinical variables were not significantly different between the two treatment groups. There was no improvement in the VAS of pain at 24 weeks. At each assessment point there was no significant difference between the steroid and placebo groups in median values for joint stiffness, joint tenderness, or patient and physician global assessments. Non-parametric analysis of each group individually revealed statistically significant improvements in patient and physician global assessments at weeks 4, 12, and 24 in the placebo group and at weeks 4 and 12 in the steroid group. Conclusions: No clinical benefit was gained from intra-articular steroid injection to the CMCJ in moderate to severe osteoarthritis compared with placebo injection. PMID:15361383

    2015-01-01

    Background: To illustrate whether the steroid-antivirals treatment could acquire a better recovery in patients with Bell’s palsy than the steroids alone treatment. Materials and methods: We conducted an exhaustive search over Pub med/Medline, Ovid, Elsevier search engines and the Cochrane library thereby collecting the randomized controlled trials in the treatment of patients with Bell’s palsy with steroid-antivirals and steroids. The qualities of relevant articles were assessed by GRADE, which was used to present the overall quality of evidence as recommended by the Cochrane Handbook for Systematic Reviews of Interventions. Results: Two investigators evaluated these papers independently, and resolved the disagreements by discussion. At last 8 eligible papers (1816 patients included: 896 treated with steroid-antivirals and 920 treated with steroids alone) match the criteria. Owing to the result (chi2 = 12.57, P = 0.08, I2 = 44%) presented by the formal test for heterogeneity, the fixed effect meta-analysis model was chosen. The facial muscle recovery between the steroids-antivirals group and the steroids alone group show significant differences (OR = 1.52, 95% CI: 1.20-1.94), while the statistical outcome of adverse effect shows no statistical significance (OR = 1.28, 95% CI: 0.71-2.31). Conclusions: The present meta-analysis indicates that the steroid-antivirals treatment could improve the recovery rate in patients with Bell’s palsy when comparing with the steroid alone treatment. Clinical significance: This meta-analysis showed that the steroid-antivirals treatment achieved the better outcomes in patients with Bell’s palsy. Clinicians should consider that steroid-antivirals therapy is an alternative choice for the patients with Bell’s palsy. PMID:25785012

    2017-10-01

    The brain has long been known as a dimorphic organ and as a target of sex steroids. It is also a site for their synthesis. Sex steroids in numerous ways can modify cerebral physiology, and along with many processes adult neurogenesis is also modulated by sex steroids. This review will focus on the effects of the main steroids, estrogens, androgens and progestogens, and unveil some aspects of their partly disclosed mechanisms of actions. Gonadal steroids act on different steps of neurogenesis: cell proliferation seems to be increased by estrogens only, while androgens and progestogens favor neuronal renewal by increasing cell survival; differentiation is a common target. Aging is characterized by a cognitive deficiency, paralleled by a decrease in the rate of neuronal renewal and in the levels of circulating gonadal hormones. Therefore, the effects of gonadal hormones on the aging brain are important to consider. The review will also be expanded to related molecules which are agonists to the nuclear receptors. Sex steroids can modify adult neuronal renewal and the extensive knowledge of their actions on neurogenesis is essential, as it can be a leading pathway to therapeutic perspectives.

  12. Treatment of central giant cell lesions using bisphosphonates with intralesional corticosteroid injections

    PubMed Central

    2012-01-01

    Central giant cell lesions are benign intraosseous proliferative lesions that have considerable local aggressiveness. Nonsurgical treatment methods, such as intralesional corticosteroid injections, systemic calcitonin and interferon have been reported. Recently, bisphosphonates have been used to treat central giant cell lesions. A case of a 36-year-old male with a central giant cell lesion crossing the mandibular midline was treated with intralesional corticosteroids combined with alendronate sodium for the control of systemic bone resorption. The steroid injections and the use of bisphosphonates were stopped after seven months when further needle penetration into the lesion was not possible due to new bone formation. After two years, the bony architecture was near normal, and only minimal radiolucency was present around the root apices of the involved teeth. The patient was followed up for four years, and panoramic radiography showed areas of new bone formation. Thus far, neither recurrence nor side effects of the medication have been detected.

  13. Designing Fault-Injection Experiments for the Reliability of Embedded Systems

    White, Allan L.

    2012-01-01

    This paper considers the long-standing problem of conducting fault-injections experiments to establish the ultra-reliability of embedded systems. There have been extensive efforts in fault injection, and this paper offers a partial summary of the efforts, but these previous efforts have focused on realism and efficiency. Fault injections have been used to examine diagnostics and to test algorithms, but the literature does not contain any framework that says how to conduct fault-injection experiments to establish ultra-reliability. A solution to this problem integrates field-data, arguments-from-design, and fault-injection into a seamless whole. The solution in this paper is to derive a model reduction theorem for a class of semi-Markov models suitable for describing ultra-reliable embedded systems. The derivation shows that a tight upper bound on the probability of system failure can be obtained using only the means of system-recovery times, thus reducing the experimental effort to estimating a reasonable number of easily-observed parameters. The paper includes an example of a system subject to both permanent and transient faults. There is a discussion of integrating fault-injection with field-data and arguments-from-design.

  14. Conserved steroid hormone homology converges on NFκB to modulate inflammation in asthma

    Asthma is a complex, multifactorial disease comprising multiple different subtypes, rather than a single disease entity [1], yet has a consistent clinical phenotype: recurring episodes of chest tightness, wheezing, and difficulty breathing. Despite the complex pathogenesis of asthma, steroid hormones (e.g. glucocorticoids) are ubiquitous in the acute and chronic management of all types of asthma. Overall, steroid hormones are a class of widely-relevant, biologically-active compounds originating from cholesterol and altered in a stepwise fashion, but maintain a basic 17-carbon, 4-ring structure. Steroids are lipophilic molecules that diffuse readily through cell membranes to directly and/or indirectly affect gene transcription. In addition, they employ rapid, non-genomic actions to affect cellular products. Steroid hormones are comprised of several groups (including glucocorticoids, sex steroid hormones, and secosteroids) with critical divergent biological and physiological functions relevant to health and disease. However, the conserved homology of steroid hormone molecules, receptors, and signaling pathways suggest that each of these is part of dynamic system of hormone interaction, likely involving overlap of downstream signaling mechanisms. Therefore, we will review the similarities and differences of these three groups of steroid hormones (i.e. glucocorticoids, sex steroid hormones, and secosteroids), identifying NFκB as a common inflammatory mediator. Despite our understanding of the impact of individual steroids (e.g. glucocorticoids, sex steroids and secosteroids) on asthma, research has yet to explain the interplay of the dynamic system in which these hormones function. To do so, there needs to be better understanding of the interplay of classical, non-classical, and non-genomic steroid hormone function. However, clues from the conserved homology steroid hormone structure and function and signaling pathways, offer insight into a possible model of steroid

    Occipital neuralgia is a form of headache that involves the posterior occiput in the greater or lesser occipital nerve distribution. Pain can be severe and persistent with conservative treatment. We present a case of intractable occipital neuralgia that conventional therapeutic modalities failed to ameliorate. We speculate that, in this case, the cause of headache could be the greater occipital nerve entrapment by the obliquus capitis inferior muscle. After steroid and local anesthetic injection into obliquus capitis inferior muscles under fluoroscopic and sonographic guidance, the visual analogue scale was decreased from 9-10/10 to 1-2/10 for 2-3 weeks. The patient eventually got both greater occipital neurectomy and partial resection of obliquus capitis inferior muscles due to the short term effect of the injection. The successful steroid and local anesthetic injection for this occipital neuralgia shows that the refractory headache was caused by entrapment of greater occipital nerves by obliquus capitis inferior muscles.

    Prolonged steroid therapy is generally used for steroid-dependent nephrotic syndrome in pediatric patients. However, dwarfism secondary to a long-term regimen and its successful reverse is rarely reported. The underlying mechanism of dwarfism is still poorly understood, as both long-term steroid use and nephrotic syndrome may interact or independently interfere with the process of growth. Here, we present a 17-year-old patient with dwarfism and steroid-dependent nephrotic syndrome and the successful treatment by recombinant human growth factor and cyclosporine A with withdrawal of steroid. We also briefly review the current understanding and the management of dwarfism in pediatric patients with nephrotic syndrome.

    A deregulation in the peripheral and brain concentrations of neuroactive steroids has been found in certain pathological conditions characterized by emotional or affective disturbances, including major depression and anxiety disorders. In this article we summarize data pertaining to the modulatory effects of oral contraceptive treatment on neuroactive steroids in women and rats. Given that the neuroactive steroids concentrations are reduced by oral contraceptives, together with the evidence that a subset of women taking oral contraceptives experience negative mood symptoms, we propose the use of this pharmacological treatment as a putative model to study the role of neuroactive steroids in the etiopathology of mood disorders. Moreover, since neuroactive steroids are potent modulators of GABA(A) receptor function and plasticity, the treatment with oral contraceptives might also represent a useful experimental model to further investigate the physiological role of these steroids in the modulation of GABAergic transmission.

    The relation between steroid hormones and pancreatic function has been poorly discussed and not very well understood. In general, there is a lack of recognition among the scientific community about the importance of steroids in pancreatic function (current paradigm). In the present article we present basic, as well as clinic and epidemiologic data that demonstrate steroid synthesis and steroid biotransformation by pancreatic tissue, how exocrine and endocrine functions are modulated by steroids, the gender specific frequency and behavior of some tumors and the use of synthetic steroids and steroid action antagonists as therapeutic agents. With the available information it is possible to establish that: 1. Pancreatic tissue synthesize and transform steroid hormones. 2. Pancreatic tissue respond to steroid hormones and express steroid specific receptor molecules. 3. Some endocrine functions such as insulin synthesis and release are modulated by steroids. 4. Tumor growth is modulated by steroids and anti-steroid drugs. This set of data creates a new paradigm for the holistic study of pancreas and opens new research fields. The application of this new paradigm might result in an increase in the knowledge of pancreatic physiology, in the design of new and better diagnostic methods and eventually in the design of more effective medical treatments for the pancreatic cancers.

    The numbers using illicit anabolic-androgenic steroids are a cause of concern for those seeking to reduce health harms. Using the 'risk environment' as a conceptual framework to better comprehend how steroid users' practices and perspectives impact on health risks, this paper examines steroid user motivations, patterns of use, and the ways in which these practices are accounted for. As part of a wider mixed-method study into performance and image enhancing drug (PIED) use and supply in one mid-sized city in South West England, qualitative interviews were undertaken with 22 steroid users. Participants were recruited from a local safer injecting service, rather than bodybuilding gyms, in order to access a wider cross-section of steroid users. A limitation of this approach is potential sample bias towards those showing more health optimising behaviours. The research findings highlight that patterns of steroid use varied according to motivation for use, experience and knowledge gained. Most reported having had little or no knowledge on steroids prior to use, with first use being based on information gained from fellow users or suppliers-sometimes inaccurate or incomplete. In accounting for their practices, many users differentiated themselves from other groups of steroid users-for example, older users expressed concern over patterns of use of younger and (what they saw as) inexperienced steroid users. Implicit in these accounts were intimations that the 'other' group engaged in riskier behaviour than they did. Examining social contexts of use and user beliefs and motivations is vital to understanding how 'risk' behaviours are experienced so that this, in turn, informs harm reduction strategies. This paper examines the ways in which use of steroids is socially situated and the implications of this for policy and practice. Copyright © 2016 Elsevier B.V. All rights reserved.

    Background It is widely accepted that cervical interlaminar steroid injection (CIESI) is more effective in treating radicular pain than axial neck pain, but without direct comparison. And the differences of effect after CIESI according to MRI findings are inconsistent. In this retrospective study, we evaluated the therapeutic response of CIESI according to pain sites, durations, MRI findings, and other predictive factors altogether, unlike previous studies, which evaluated them separately. Methods The medical records of 128 patients who received fluoroscopy guided CIESI were analyzed. We evaluated the therapeutic response (more than a 50% reduction on the visual analog scale [VAS] by their second visit) after CIESI by (1) pain site; neck pain without radicular pain/radicular pain with or without neck pain, (2) pain duration; acute/chronic (more than 6 month), and (3) findings of MRI; herniated intervertebral disc (HIVD)/spinal stenosis, respectively and altogether. Results Eighty-eight patients (68%) responded to CIESI, and there were no significant differences in demographic data, initial VAS score, or laboratory findings. And there were no significant differences in the response rate relating to pain site, pain duration, or MRI findings, respectively. In additional analysis, acute radicular pain with HIVD patients showed significantly better response than chronic neck pain with spinal stenosis (P = 0.04). Conclusions We cannot find any sole predictive factor of therapeutic response to the CIESI. But the patients having acute radicular pain with HIVD showed the best response, and those having other chronic neck pain showed the worst response to CIESI. PMID:27103964

    This report presents the results of an investigation to determine experimentally the instantaneous pressures at the discharge orifice of a common-rail fuel injection system in which the timing valve and cut-off valve were at some distance from the automatic fuel injection valve, and also to determine the methods by which the pressure fluctuations could be controlled. The results show that pressure wave phenomena occur between the high-pressure reservoir and the discharge orifice, but that these pressure waves can be controlled so as to be advantageous to the injection of the fuel. The results also give data applicable to the design of such an injection system for a high-speed compression-ignition engine.

    Chronic persistent neck pain with or without upper extremity pain is common in the general adult population with prevalence of 48% for women and 38% for men, with persistent complaints in 22% of women and 16% of men. Multiple modalities of treatments are exploding in managing chronic neck pain along with increasing prevalence. However, there is a paucity of evidence for all modalities of treatments in managing chronic neck pain. Cervical epidural injections for managing chronic neck pain are one of the commonly performed interventions in the United States. However, the literature supporting cervical epidural steroids in managing chronic pain problems has been scant. A systematic review of cervical interlaminar epidural injections for cervical disc herniation, cervical axial discogenic pain, cervical central stenosis, and cervical postsurgery syndrome. To evaluate the effect of cervical interlaminar epidural injections in managing various types of chronic neck and upper extremity pain emanating as a result of cervical spine pathology. The available literature on cervical interlaminar epidural injections in managing chronic neck and upper extremity pain were reviewed. The quality assessment and clinical relevance criteria utilized were the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials and the criteria developed by the Newcastle-Ottawa Scale criteria for observational studies. The level of evidence was classified as good, fair, and limited based on the quality of evidence developed by the U.S. Preventive Services Task Force (USPSTF). Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to December 2011, and manual searches of the bibliographies of known primary and review articles. The primary outcome measure was pain relief (short-term relief = up to 6 months and long-term > 6 months). Secondary outcome measures were improvement in functional status

    Sexual dimorphism is a characteristic of a large number of species, ranging from lower invertebrates to mammals and, last but not least, humans. Recognition of the various factors regulating sexual dimorphism initial establishment (i.e. sex determination and differentiation) and subsequent life-long adaptation to distinct functional and behavioural patterns has remained a hot topic for several decades. As our understanding of the various molecular pathways involved in this process increases, the significant role of sex steroids becomes more evident. At the same time, the recognition of new sites of steroid production (e.g. parts of the brain) and aromatization, as well as new target cells (owing to the proposed presence of additional receptors to those classically considered as primary steroid receptors) has lead to the need to revisit their spectrum of actions within a novel, multifactorial context. Thus, anthropology and medicine are presented with the challenge to unravel a major mystery, i.e. that of sexual orientation and differentiation and its potential contribution in human evolution and civilization development, taking advantage of the high-tech research tools provided by modern biotechnology. This short review summarizes the basic principles of sex determination and sex steroid function as they have been classically described in the literature and then proceeds to present examples of how modern research methods have started to offer a new insight on the more subtle details of this process, stressing that it is extending to virtually every single part and system of the body.

    Athletes and bodybuilders have recognized for several decades that the use of anabolic steroids can promote muscle growth and strength but it is only relatively recently that these agents are being revisited for clinical purposes. Anabolic steroids are being considered for the treatment of cachexia associated with chronic disease states, and to address loss of muscle mass in the elderly, but nevertheless their efficacy still needs to be demonstrated in terms of improved physical function and quality of life. In sport, these agents are performance enhancers, this being particularly apparent in women, although there is a high risk of virilization despite the favourable myotrophic-androgenic dissociation that many xenobiotic steroids confer. Modulation of androgen receptor expression appears to be key to partial dissociation, with consideration of both intracellular steroid metabolism and the topology of the bound androgen receptor interacting with co-activators. An anticatabolic effect, by interfering with glucocorticoid receptor expression, remains an attractive hypothesis. Behavioural changes by non-genomic and genomic pathways probably help motivate training. Anabolic steroids continue to be the most common adverse finding in sport and, although apparently rare, designer steroids have been synthesized in an attempt to circumvent the dope test. Doping with anabolic steroids can result in damage to health, as recorded meticulously in the former German Democratic Republic. Even so, it is important not to exaggerate the medical risks associated with their administration for sporting or bodybuilding purposes but to emphasize to users that an attitude of personal invulnerability to their adverse effects is certainly misguided.

    Transforaminal epidural steroid injections (TFESI) are a mainstay in the treatment of spine pain. Though this commonly performed procedure is generally felt to be safe, devastating complications following inadvertent intra-arterial injections of particulate steroid have been reported. The use of digital subtraction angiography (DSA) has been suggested as a means of detecting intra-arterial needle placements prior to medication injection. To examine the efficacy of DSA in detecting intra-arterial needle placements during TFESI. Prospective cohort study evaluating the impact of DSA on detecting intra-arterial needle placements during TFESI. We enrolled 150 consecutive patients presenting to a university-affiliated spine center with discogenic and/or radicular symptoms affecting the cervical, lumbar, and sacral regions. For each injection, prior to imaging with DSA, traditional methods for vascular penetration detection were employed, including the identification of blood in the needle hub (flash), negative aspiration of blood prior to injection, and live fluoroscopic injection of contrast. Once these tests were performed and negative for signs of intra-arterial needle placement, DSA imaging was utilized prior to medication administration for identification of vascular flow. A total number of 222 TFESI were performed, 41 injections at the cervical levels (18.47%), 113 at the lumbar levels (50.9%), and 68 at the sacral levels (30.36%). Flash was observed in 13 injections performed (5.85% of the total number of injections): one (0.45%) in the cervical, 2 (0.9%) in the lumbar, and 10 (4.5%) in the sacral levels. In 11 TFESI blood aspiration was obtained (4.95% of all injections): 3 (1.3%) in cervical, 4 (1.8%) in lumbar, and 4 (1.8%) in sacral injections. Live fluoroscopy during contrast injection detected 46 (20.72%) intravascular flow patterns: 7 (3.1%) cervical, 17 (7.6%) lumbar, and 22 (9.9%) sacral. DSA identified an additional 5 intravascular injections after all

    Antenatal steroid treatment to enhance fetal lung maturity and surfactant treatment to prevent or treat respiratory distress syndrome have been major advances in perinatal medicine in the past 40 years contributing to improved outcomes for preterm infants. Use of postnatal steroids to prevent or treat chronic lung disease in preterm infants has been less successful and associated with adverse neurodevelopmental outcomes. Although early (in the first week of life) postnatal steroid treatment facilitates earlier extubation and reduces the risk of chronic lung disease, it is associated with adverse effects, such as hyperglycemia, hypertension, gastrointestinal bleeding and perforation, hypertrophic cardiomyopathy, growth failure, and cerebral palsy, and cannot be recommended. Early treatment with hydrocortisone may also improve survival without chronic lung disease, but concerns remain about possible adverse effects such as gastrointestinal perforation and sepsis, particularly in very preterm infants. Early inhaled budesonide also reduces the incidence of chronic lung disease but there are concerns that this may occur at the expense of increased risk of death. More studies of early low-dose steroids with adequate long-term follow-up are needed before they can be recommended for the prevention of chronic lung disease. Late (after the first week of life) postnatal steroids may have a better benefit-to-harm ratio than early steroids. A Cochrane Review shows that late steroid treatment reduces chronic lung disease, the combination of death and chronic lung disease at both 28 days and 36 weeks' corrected age, and the need for later rescue dexamethasone. Adverse effects include hyperglycemia, hypertension, hypertrophic cardiomyopathy, and severe retinopathy of prematurity but without an increase in blindness. Long-term neurodevelopmental effects are not significantly increased by late postnatal steroid treatment. Current recommendations are that postnatal steroid treatment

    In this study, the fate of steroid hormones in beef cattle manure composting is evaluated. The fate of 16 steroids and metabolites was evaluated in composted manure from beef cattle administered growth promotants and from beef cattle with no steroid hormone implants. The fate of estrogens (primary detected as estrone), androgens, progesterone, and the fusarium metabolite and implant α-zearalanol was monitored in manure compost piles. First-order decay rates were calculated for steroid half-lives in compost and ranged from 8 d for androsterone to 69 d for 4-androstenedione. Other steroid concentration data could not be fit to first-order decay models, which may indicate that microbial processes may result in steroid production or synthesis in composting systems. We demonstrate that composting is an effective strategy to remove steroid hormones from manure. Total steroid hormone removal in composted beef cattle manure ranged from 79 to 87%.

    To evaluate the health-related quality of life effects of muscle stretching, manual therapy and steroid injections in addition to 'stay active' care in acute or subacute low back pain patients. A randomized, controlled trial during 10 weeks with four treatment groups. Nine primary health care and one outpatient orthopaedic hospital department. One hundred and sixty patients with acute or subacute low back pain. Ten weeks of 'stay active' care only (group 1), or 'stay active' and muscle stretching (group 2), or 'stay active', muscle stretching and manual therapy (group 3), or 'stay active', muscle stretching, manual therapy and steroid injections (group 4). The Gothenburg Quality of Life instrument subscales Well-being score and Complaint score. In a multivariate analysis adjusted for possible outcome affecting variables other than the treatment given Well-being score was 68.4 (12.5), 72.1 (12.4), 72,3 (12.4) and 72.7 (12.5) in groups 1-4, respectively (P for trend <0.05). There were significant trends for the well-being components patience (P < 0.005), energy (P < 0.05), mood (P < 0.05) and family situation (P < 0.05). The remaining two components and Complaint score showed a non-significant trend towards improvement. The effects on health-related quality of life were greater the larger the number of treatment modalities available. The 'stay active' treatment group, with the most restricted number of modalities, had the most modest health-related quality of life improvement, while group 4 with the most generous choice of treatment modalities, had the greatest improvement.

    The copulatory neuromuscular system of green anoles is sexually dimorphic and differentiates during embryonic development, although details of the process were unknown. In Experiment 1, we determined the time course of normal ontogeny. Both male and female embryos possessed bilateral copulatory organs (hemipenes) and associated muscles until incubation day 13; the structures completely regressed in female embryos by incubation day 19 (total incubation 34 days). In Experiment 2, we treated eggs with testosterone, dihydrotestosterone, estradiol, or vehicle on both incubation days 10 and 13 to determine whether these steroid hormones mediate sexual differentiation. These time points fall between gonadal differentiation, which was determined in Experiment 1 to complete before day 10, and regression of the peripheral copulatory system in females. Tissue was collected on the day of hatching. Gonads were classified as testes or ovaries; presence versus absence of hemipenes and muscles, and the number and size of copulatory motoneurons were determined. Copulatory system morphology of vehicle-treated animals matched their gonadal sex. Hemipenes and muscles were absent in estradiol-treated animals, and androgens rescued the hemipenes and muscles in most females. Both testosterone and dihydrotestosterone treatment also caused hypertrophy of the hemipenes, which were everted in animals treated with these steroids. Copulatory motoneurons, assessed on the day of hatching in both experiments, were not dimorphic in size or number. Steroid treatment significantly increased motoneuron size and number overall, but no significant differences were detected in pairwise comparisons. These data demonstrate that differentiation of peripheral copulatory neuromuscular structures occurs during embryonic development and is influenced by gonadal steroids (regression by estradiol and enhancement by androgens), but associated motoneurons do not differentiate until later in life.

    BACKGROUND: Studies on peripheral benzodiazepine receptor function have yielded a diverse list of activities of which the anti-inflammatory effects need to be further examined. AIMS: To evaluate the role of steroids, nitric oxide and adenosine-deaminase in the anti-inflammatory effect of PK11195. METHODS: Pleurisy was induced by intrapleural injection of carrageenan in mice pre-treated or not with PK11195. Leukocytes, exudation, adenosine-deaminase (ADA) activity and nitric oxide (NO) level were measured. Steroid involvement was evaluated by pre-treatment with D,L-aminogluthetimide before PK11195. RESULTS: Leukocytes, exudation and NO levels were reduced by PK11195 in the early (4 h) phase. In the late (48 h) phase, PK11195 decreased leukocytes and ADA activity. D,L-aminogluthetimide reversed the effect of PK11195 on exudate (4 h), as well as total and differential leukocytes and NO levels (48 h). CONCLUSIONS: Steroids, NO and ADA are implicated in the anti-inflammatory action of PK11195. PMID:15203550

    Apparatus for eliminating siphoning, "dead" regions, and fluid concentration gradients in microscale analytical devices. In its most basic embodiment, the present invention affords passive injection control for both electric field-driven and pressure-driven systems by providing additional fluid flow channels or auxiliary channels disposed on either side of a sample separation column. The auxiliary channels are sized such that volumetric fluid flow rate through these channels, while sufficient to move the sample away from the sample injection region in a timely fashion, is less than that through the sample separation channel or chromatograph.

    Intratympanic injections or titration is a potential medical therapeutic strategy for patients with incurable inner ear diseases. Dexamethasone represent an attractive steroid source in intratympanic steroids strategies in the treatment of inner ear disorders. Here, we evaluated the effectiveness of intratympanic dexamethasone injections (IDI) in outpatients with refractory Meniere’s disease (MD). Vestibular function measured by Vestibular Ocular Reflex (VOR) gain and caloric test revealed that 21 outpatients out of 43 (48.8%) had complete sufficient vertigo control, while 9 (20.9%) of them were attached to fundamental manipulation. Out of the 13 remaining outpatients, 4 (9.3%) had a limit control and 9 had less modification. Therefore, 5 of 9 received re-treatment with IDI and 2 of 9 patients were administered ablative treatment with gentamicin. Meanwhile, audiology data suggested that 3 (7.0%), 4 (9.3%), 32 (74.4%), 4 (9.3%) patients were attached to the level of A, B, C, D, respectively. Furthermore, the symptom of tinnitus in 5 outpatients vanished, 21 (48.8%) diminished, 10 (23.3%) invariable, 7 (16.3%) aggravated. In 4 of 24 cases (16.7%), aural fullness disappeared after IDI, when the aural fullness was alleviated in 11 cases (45.8%) even intensive in 9 patients (37.5%). Together, our results demonstrate that intratympanic dexamethasone injection, as an effective therapeutic strategy for refractory Meniere’s disease, could either be used for cascade therapy preoperation or used for patients who couldn’t accept the surgery.

    2016-02-01

    Growth factors acting through receptor tyrosine kinases (RTKs) of ERBB family, along with steroid hormones (SH) acting through nuclear receptors (NRs), are critical signalling mediators of cellular processes. Deregulations of ERBB and steroid hormone receptors are responsible for several diseases, including cancer, thus demonstrating the central role played by both systems. This review will summarize and shed light on an emerging crosstalk between these two important receptor families. How this mutual crosstalk is attained, such as through extensive genomic and non-genomic interactions, will be addressed. In light of recent studies, we will describe how steroid hormones are able to fine-tune ERBB feedback loops, thus impacting on cellular output and providing a new key for understanding the complexity of biological processes in physiological or pathological conditions. In our understanding, the interactions between steroid hormones and RTKs deserve further attention. A system biology approach and advanced technologies for the analysis of RTK-SH crosstalk could lead to major advancements in molecular medicine, providing the basis for new routes of pharmacological intervention in several diseases, including cancer.

    In an effort to begin to construct a psychological profile of anabolic steroid users, the authors compared weight lifters and bodybuilders who did or did not use anabolic steroids on an objective measure of narcissism and on clinical ratings of empathy. The subjects were 16 weight lifters and bodybuilders who reported that they had used anabolic steroids within the past year and a comparison group of 20 weight lifters who had not used steroids. The Narcissistic Personality Inventory and clinical ratings of empathy were used to assess narcissism. Steroid users had significantly higher scores on dimensions of pathological narcissism and significantly lower scores on clinical ratings of empathy. These preliminary results document a relationship between anabolic steroid use and narcissistic personality traits. They also indicate the need for further research to determine whether narcissistic personality traits contribute to the initiation of anabolic steroid use or result from their use.

    Subacromial pain syndrome (SAPS) accounts for around 50 % of all cases of shoulder pain. The most commonly used treatments are glucocorticosteroid (steroid) injections and exercise therapy; however, despite treatment SAPS patients often experience relapse of their symptoms. Therefore the clinical effect of combining steroid and exercise therapy is highly relevant to clarify. The aim of this randomized controlled trial was to investigate if exercise therapy added to steroid injection in patients with SAPS will improve the effect of the injection therapy on shoulder pain. In this two-arm randomized trial running over 26 weeks, patients with unilateral shoulder pain (> 4 weeks) and thickened subacromial bursa (> 2 mm on US) were included. At baseline all participants received two steroid injections into the painful shoulder with an interval of one week. Subsequently they were randomized (1:1) to either 10 weeks exercise of the involved shoulder (intervention group) or exercise of the uninvolved shoulder (control group). The patients were re-examined after the exercise program (at week 13) and again at week 26. The primary outcome assessed after 26 weeks was change in shoulder pain analyzed using the intention-to-treat principle (non-responder imputation). Ninety-nine SAPS patients (58 female) participated (49 intervention/50 control). At both follow up visits (week 13 and 26) no statistically significant between-group differences in pain changes on a visual analog scale (mm) were seen (13 weeks: pain at rest 1.7 (95 % CI -3.6 to 7.0; P = 0.53); pain in activity 2.2 (95 % CI -6.5 to 10.9; P = 0.61), 26 weeks: rest 5.6 (95 % CI -0.9 to 12.1; P = 0.09); activity 2.2 (95 % CI -6.8 to 11.2; P = 0.62). The reduction in pain was most evident in the control group at all four pain measurements. The only difference between groups was seen by US examination at week 13, where fewer participants with impingement were observed in the intervention group compared

    A large number of patients with Bell's palsy fail to recover facial function completely after steroid therapy. Only a few small trials have been conducted to test whether outcomes can be improved by the addition of antiviral therapy. To evaluate the efficacy of treatment with steroid alone versus steroid + antiviral in a group of patients with moderately severe to severe acute Bell's palsy. Fifty eligible patients out of a total of 65 with acute onset Bell's palsy were randomized to receive the two treatments. Evaluation was performed before starting treatment, after 2 weeks of treatment and 3 months after onset, using the House and Brackmann facial nerve grading system (HB) and the Sunnybrook grading system.This study was registered with ClinicalTrials.gov, number NCT02328079. Both treatments had comparable demographics and clinical scores at baseline. There was greater improvement in the mean HB and Sunnybrook scores of the steroid + antiviral group in comparison to steroid group at 3 months. At the end of the 3rd month, 17 patients (68%) had good recovery and 8 patients (32%) had poor recovery in the steroid group compared with 23 patients (92%) and 2 (8%) respectively in the steroid and antiviral group (p = 0.034). The combination of steroid and antiviral treatment increases the possibility of recovery in moderately severe to complete acute Bell's palsy.

    To report a case of Purtscher-like retinopathy with paracentral acute middle maculopathy preceded by febrile illness after filler injection into the buttock muscles bilaterally for cosmesis to achieve a "Brazilian booty." Retrospective case report. A 35-year-old female presented with febrile illness and then decreased vision after repeat polymethyl methacrylate injections into her buttock muscles in Mexico. Examination was significant for retinal whitening, especially in the perifoveal areas, and intraretinal hemorrhages. Optical coherence tomography and fluorescein angiography imaging were consistent with small-vessel ischemic disease in the retina and choroid. Once systemic infection was ruled out, patient was treated with high-dose intravenous and then oral steroids. Vision recovery was good, with retinal atrophy on optical coherence tomography in the previous areas of retinal whitening. A Purtscher-like retinopathy with paracentral acute middle maculopathy and loss of vision may occur after filler injection below the neck, not just the face. This is the first report of vision loss caused by filler injected outside the face.

  5. Steroid hormones, stress and the adolescent brain: a comparative perspective.

    Steroid hormones, including those produced by the gonads and the adrenal glands, are known to influence brain development during sensitive periods of life. Until recently, most brain organisation was assumed to take place during early stages of development, with relatively little neurogenesis or brain re-organisation during later stages. However, an increasing body of research has shown that the developing brain is also sensitive to steroid hormone exposure during adolescence (broadly defined as the period from nutritional independence to sexual maturity). In this review, we examine how steroid hormones that are produced by the gonads and adrenal glands vary across the lifespan in a range of mammalian and bird species, and we summarise the evidence that steroid hormone exposure influences behavioural and brain development during early stages of life and during adolescence in these two taxonomic groups. Taking a cross-species, comparative perspective reveals that the effects of early exposure to steroid hormones depend upon the stage of development at birth or hatching, as measured along the altricial-precocial dimension. We then review the evidence that exposure to stress during adolescence impacts upon the developing neuroendocrine systems, the brain and behaviour. Current research suggests that the effects of adolescent stress vary depending upon the sex of the individual and type of stressor, and the effects of stress could involve several neural systems, including the serotonergic and dopaminergic systems. Experience of stressors during adolescence could also influence brain development via the close interactions between the stress hormone and gonadal hormone axes. While sensitivity of the brain to steroid hormones during early life and adolescence potentially leaves the developing organism vulnerable to external adversities, developmental plasticity also provides an opportunity for the developing organism to respond to current circumstances and for behavioural

    2014-01-01

    Background Localized inflammation of lumbar dorsal root ganglia (DRG) may contribute to low back pain. Local injections of corticosteroids used for low back pain are sometimes ineffective. Many corticosteroids activate not only the target glucocorticoid receptor (GR) but also the mineralocorticoid receptor (MR), which may have pro-inflammatory effects countering the effects of GR activation. Methods A low back pain model was implemented in rats (n = 6 -10 per group) by locally inflaming the L5 DRG. Sensory neuron excitability and mechanical hypersensitivity of the hind paws were measured. Tested steroids were applied locally to the inflamed DRG or orally. Results The selective MR blocker eplerenone reduced pain behaviors when given orally starting at the time of surgery, or starting 7 days later. The highly GR-selective agonist fluticasone, applied locally to the inflamed DRG, was much more effective in reducing mechanical hypersensitivity. The MR/GR agonist 6-α methylprednisolone, commonly injected for low back pain, reduced mechanical hypersensitivity when applied locally to the DRG, but was less effective than fluticasone. Its effectiveness was improved by combining it with local eplerenone. All tested steroids reduced hyperexcitability of myelinated sensory neurons (n = 71 – 220 cells per group) after inflammation, particularly abnormal spontaneous activity. Conclusions This preclinical study indicates the MR may play an important role in low back pain involving inflammation. Some MR effects may occur at the level of the sensory neuron. It may be useful to consider the action of clinically used steroids at the MR as well as at the GR. PMID:24781496

    2012-01-01

    Sex differences in the biology of different organ systems and the influence of sex hormones in modulating health and disease are increasingly relevant in clinical and research areas. Although work has focused on sex differences and sex hormones in cardiovascular, musculoskeletal, and neuronal systems, there is now increasing clinical evidence for sex differences in incidence, morbidity, and mortality of lung diseases including allergic diseases (such as asthma), chronic obstructive pulmonary disease, pulmonary fibrosis, lung cancer, as well as pulmonary hypertension. Whether such differences are inherent and/or whether sex steroids play a role in modulating these differences is currently under investigation. The purpose of this review is to define sex differences in lung structure/function under normal and specific disease states, with exploration of whether and how sex hormone signaling mechanisms may explain these clinical observations. Focusing on adult age groups, the review addresses the following: 1) inherent sex differences in lung anatomy and physiology; 2) the importance of certain time points in life such as puberty, pregnancy, menopause, and aging; 3) expression and signaling of sex steroid receptors under normal vs. disease states; 4) potential interplay between different sex steroids; 5) the question of whether sex steroids are beneficial or detrimental to the lung; and 6) the potential use of sex steroid signaling as biomarkers and therapeutic avenues in lung diseases. The importance of focusing on sex differences and sex steroids in the lung lies in the increasing incidence of lung diseases in women and the need to address lung diseases across the life span.

    This study compared the therapeutic efficacy of steroidal and non-steroidal agents for treating oral lichen planus. Forty patients with clinical and/or histologically proven oral lichen planus were randomly placed into four groups and treated with topical triamcinolone, oral dapsone, topical tacrolimus or topical retinoid for three months. Pre- and post-treatment symptoms and signs were scored for each patient. Patients in all treatment groups showed significant clinical improvement after three months (p 0.05) and for topical retinoid vs topical tacrolimus (p > 0.05). Non-steroidal drugs such as dapsone, tacrolimus and retinoid are as efficacious as steroidal drugs for treating oral lichen planus, and avoid the side effects associated with steroids.

    This paper investigates the safety of a novel 'magnetic injection' method of delivering therapy to the cochlea, in a rodent model. In this method of administration, a magnetic field is employed to actively transport drug-eluting iron oxide-core nanoparticles into the cochlea, where they then release their drug payload (we delivered the steroid prednisolone). Our study design and selection of control groups was based on published regulatory guidance for safety studies that involve local drug delivery. We tested for both single and multiple delivery doses to the cochlea, and found that magnetic delivery did not harm hearing. There was no statistical difference in hearing between magnetically treated ears versus ears that received intra-tympanic steroid (a mimic of a standard-of-care for sudden sensorineural hearing loss), both 2 and 30 days after treatment. Since our treatment is local to the ear, the levels of steroid and iron circulating systemically after our treatment were low, below mass-spectrometry detection limits for the steroid and no different from normal for iron. No adverse findings were observed in ear tissue histopathology or in animal gross behavior. At 2 and 30 days after treatment, inflammatory changes in the ear were limited to the middle ear, were very mild in severity, and by day 90 there was ongoing and almost complete reversibility of these changes. There were no ear tissue scarring or hemorrhage trends associated with magnetic delivery. In summary, after conducting a pre-clinical safety study based on FDA guidance documents, no adverse safety issues were observed. Copyright © 2017. Published by Elsevier B.V.

    Within the combined DFG research project "Sulfated Steroids in Reproduction" an analytical method was needed for determining sulfated and unconjugated steroids with highest specificity out of different biological matrices such as aqueous solution, cell lysate and serum. With regard to this analytical challenge, LC-MS-MS presents the technique of choice because it permits (1) analysis of the intact steroid conjugate, (2) allows for simultaneous determination of multiple analytes (profiling, targeted metabolomics approach) and (3) is independent of phenomena such as cross-reactivity. Sample work up consisted of incubation of sample with internal standards (deuterium labeled steroids) followed by solid phase extraction. Only serum samples required a protein precipitation step prior to solid phase extraction. The extract was divided in two parts: six steroid sulfates (E1S, E2S, AS, 16-OH-DHEAS, PREGS, DHEAS) were analyzed by C18aQ-ESI-MS-MS in negative ion mode and eleven unconjugated steroids (E3, 16-OH-DHEA, E1, E2, (4)A, DHEA, T, 17-OH-PREG, Prog, An, PREG) were analyzed by C18-APCI-MS-MS in positive ion mode. For steroid sulfates, we found high sensitivities with LoQ values ranging from 0.08 to 1 ng mL(-1). Unconjugated steroids showed LoQ values between 0.5 and 10 ng mL(-1). Calibration plots showed excellent linearity. Mean intra- and inter-assay CVs were 2.4% for steroid sulfates and 6.4% for unconjugated steroids. Accuracy - determined in a two-level spike experiment - showed mean relative errors of 5.9% for steroid sulfates and 6.1% for unconjugated steroids. In summary, we describe a novel LC-MS-MS procedure capable of profiling six steroid sulfates and eleven unconjugated steroids from various biological matrices.

    Anabolic androgenic steroids (AAS) use by adolescents is steadily increasing. Adolescence involves remodeling of steroid-sensitive neural circuits that mediate social behaviors, and previous studies using animal models document effects of AAS on male social behaviors. The present experiments tested whether AAS have persistent and more pronounced behavioral consequences when drug exposure occurs during adolescence as compared to exposure in adulthood. Male Syrian hamsters were injected daily for 14 days with either vehicle or an AAS cocktail containing testosterone cypionate (2 mg/kg), nandrolone decanoate (2 mg/kg), and boldenone undecylenate (1 mg/kg), either during adolescence (27-41 days of age) or adulthood (63-77 days of age). As adults, subjects were tested two or four weeks after the last injection for either sexual behavior with a receptive female or male-male agonistic behavior in a resident-intruder test. Compared with vehicle-treated males, AAS-treated males, regardless of age of treatment, displayed fewer long intromissions and a significant increase in latency to the first long intromission, indicative of reduced potential to reach sexual satiety. Increased aggression was observed in males exposed to AAS compared with males treated with vehicle, independently of age of AAS treatment. However, unlike hamsters exposed to AAS in adulthood, hamsters exposed to AAS during adolescence did not display any submissive or risk-assessment behaviors up to 4 weeks after discontinuation of AAS treatment. Thus, AAS have long-lasting effects on male sexual and agonistic behaviors, with AAS exposure during adolescence resulting in a more pronounced reduction in submissive behavior compared to AAS exposure in adulthood.

    A system for monitoring and controlling the injection rate of fluid by an injection well of an in-situ remediation system for treating a contaminated groundwater plume. The well is fitted with a gated insert, substantially coaxial with the injection well. A plurality of openings, some or all of which are equipped with fluid flow sensors and gates, are spaced along the insert. The gates and sensors are connected to a surface controller. The insert may extend throughout part of, or substantially the entire length of the injection well. Alternatively, the insert may comprise one or more movable modules which can be positioned wherever desired along the well. The gates are opened part-way at the start of treatment. The sensors monitor and display the flow rate of fluid passing through each opening on a controller. As treatment continues, the gates are opened to increase flow in regions of lesser flow, and closed to decrease flow in regions of greater flow, thereby approximately equalizing the amount of fluid reaching each part of the plume.

    This protocol describes a method for in vivo measurement of steroid hormones in brain circuits of the zebra finch. In vivo microdialysis has been used successfully to detect fluctuating neurosteroids in the auditory forebrain (Remage-Healey et al., 2008; 2012; Ikeda et al., 2012) and in the hippocampus (Rensel et al., 2012; 2013) of behaving adult zebra finches. In some cases, the steroids measured are derived locally (e.g., ‘neurosteroids’ like estrogens in males) whereas in other cases the steroids measured reflect systemic circulating levels and/or central conversion (e.g., the primary androgen testosterone and the primary glucocorticoid corticosterone). We also describe the method of reverse-microdialysis (‘retrodialysis’) of compounds that can influence local steroid neurochemistry as well as behavior. In vivo microdialysis can now be used to study steroid signaling in the brain for a variety of experimental purposes. Furthermore, similar methods have been developed to examine changing levels of catecholamines in behaving zebra finches (e.g., Sasaki et al., 2006). Thus, the combined study of neurochemistry and behavior in a vocal learning species now has a new set of powerful tools. PMID:25342066

    SIRT1 is a highly-conserved NAD+-dependent protein deacetylase that plays essential roles in the regulation of energy metabolism, genomic stability, and stress response. Although the functions of SIRT1 in many organs have been extensively studied in tissue-specific knockout mouse models, the systemic role of SIRT1 is still largely unknown as a result of severe developmental defects that result from whole-body knockout in mice. Here, we investigated the systemic functions of SIRT1 in metabolic homeostasis by utilizing a whole-body SIRT1 heterozygous mouse model. These mice are phenotypically normal under standard feeding conditions. However, when chronically challenged with a 40% fat diet, they become obese and insulin resistant, display increased serum cytokine levels, and develop hepatomegaly. Hepatic metabolomic analyses revealed that SIRT1 heterozygous mice have elevated gluconeogenesis and oxidative stress. Surprisingly, they are depleted of glycerolipid metabolites and free fatty acids, yet accumulate lysolipids. Moreover, high-fat feeding induces elevation of serum testosterone levels and enlargement of seminal vesicles in SIRT1 heterozygous males. Microarray analysis of liver mRNA indicates that they have altered expression of genes involved in steroid metabolism and glycerolipid metabolism. Taken together, our findings indicate that SIRT1 plays a vital role in the regulation of systemic energy and steroid hormone homeostasis.—Purushotham, A., Xu, Q., Li, X.

    The quantification of endogenous steroid hormone concentrations in hair is increasingly used as a method for obtaining retrospective information on long-term integrated hormone exposure. Several different analytical procedures have been employed for hair steroid analysis, with liquid chromatography-mass spectrometry (LC-MS) being recognized as a particularly powerful analytical tool. Several methodological aspects affect the performance of LC-MS systems for hair steroid analysis, including sample preparation and pretreatment, steroid extraction, post-incubation purification, LC methodology, ionization techniques and MS specifications. Here, we critically review the differential value of such protocol variants for hair steroid hormones analysis, focusing on both analytical quality and practical feasibility issues. Our results show that, when methodological challenges are adequately addressed, LC-MS protocols can not only yield excellent sensitivity and specificity but are also characterized by relatively simple sample processing and short run times. This makes LC-MS based hair steroid protocols particularly suitable as a high-quality option for routine application in research contexts requiring the processing of larger numbers of samples.

    Adrenal insufficiency has been reported among critically ill HIV-infected patients. This is the first study that attempts to detect subclinical hypoadrenal states in non-critical HIV patients through salivary steroids in response to intramuscular low-dose ACTH injection. We studied 21 ambulatory adult HIV-infected patients without specific clinical signs or symptoms of adrenal insufficiency. Normal salivary flow-rate and salivary alpha-amylase activity confirmed adequate salivary gland function. Salivary cortisol (SAF) and salivary aldosterone (SAL) were obtained at baseline and 30 min after the injection of 25 microg of ACTH in the deltoid muscle (LDT(s)). Assessment of salivary steroids after stimulation with 250 microg of intramuscular ACTH (HDT(s)) was performed on those who hyporesponded to LDT(s). Basal blood samples were drawn for steroids, renin and ACTH measurements. At baseline SAF and SAL correlated significantly (p=0.0001) with basal serum cortisol and aldosterone (r=0.70 and 0.91, respectively). Plasma ACTH and renin concentrations were within the normal range in all patients. Eight of the twenty-one HIV(+) patients were LDT(s) hyporesponders in either SAF (n:1) or SAL (n:7). LDT(s) repeated in six cases after a year reconfirmed the impairment of aldosterone secretion. LDT(s) hyporesponders had normal steroid responses to HDT(s). LDT(s) is a simple, safe, well-accepted and non-invasive approach to assess adrenal function in HIV-infected ambulatory patients. It revealed subnormal cortisol (5%) and aldosterone responses (33%) when HDT(s) results were normal.

    The objective of this study was to investigate the protective effects of molecular hydrogen, a novel and selective antioxidant, on steroid-induced osteonecrosis (ON) in a rabbit model. Sixty rabbits were randomly divided into two groups (model group and hydrogen group). Osteonecrosis was induced according to an established protocol of steroid-induced ON. Rabbits in the hydrogen group were treated with intraperitoneal injections of molecular hydrogen at 10 ml/kg body weight for seven consecutive days. Plasma levels of total cholesterol, triglycerides, soluble thrombomodulin(sTM), glutathione(GSH) and malondialdehyde(MDA) were measured before and after steroid administration. The presence or absence of ON was examined histopathologically. Oxidative injury and vascular injury were assessed in vivo by immunohistochemical staining of 8-hydoxy-2-deoxyguanosine(8-OHdG) and MDA, and ink artery infusion angiography. The terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assays were performed to measure apoptosis. The incidence of steroid-induced ON was significantly lower in hydrogen group (28.6%) than that in model group (68.0%). No statistically differences were observed on the levels of total cholesterol and triglycerides. Oxidative injury, vascular injury and apoptosis were attenuated in the hydrogen group compared with those in the model group in vivo. These results suggested that molecular hydrogen prevents steroid-induced osteonecrosis in rabbits by suppressing oxidative injury, vascular injury and apoptosis.

    Currently, dozens of anabolic androgenic steroids (AAS) are forbidden in the World Anti-Doping Agency Prohibited List, however, despite extensive investigation, there are still lots of AAS without corresponding monoclonal antibodies. A steroid analog antigen microarray made up of ten AAS was fabricated to screen the hybridoma and it was found an original unsuccessful clone turned out to be a candidate anti-boldenone antibody, without any cross-reactions with endogenous AAS or 44 different AAS standard reference materials tested. Our findings suggested that steroid analog antigen microarray could be a promising tool to screen and characterize new applications of antibodies for structure analogs, and this also exhibits the potential to fast identify effective epitopes of hybridomas in a single assay.

    The purpose of the role of antioxidant enzymes and mitochondria in the developmental mechanism of steroid-associated osteonecrosis in the femur. In the present study Japanese white rabbits (mean weight 3.5kg) were injected into the gluteus with methylprednisolone (MP) 20mg/kg, and killed after 3 days (MP3 group), 5 days (MP5 group), and 14 days (MP14 group) (n=3 each). As a Control group (C group) Japanese white rabbits not administered MP were used. In experiment 1, the expression of the antioxidant enzymes Superoxide dismutade (SOD) and catalase was compared in liver, kidney, heart, humerus, and femur in C group, and the presence/absence of mitochondria transcription factor A (TFAM) expression was determined by Western blotting (WB) and used to evaluate the number of mitochondria and their function. In experiment 2, the presence/absence of necrosis was determined by immunohistochemistry, while changes in the expression of SOD, catalase, and TFAM in the femur after steroid administration were determined by Western blotting (WB). In experiment 1, intense expression of all of SOD, catalase, and TFAM was found in the liver, kidney, and heart as compared to the humerus and femur. In experiment 2, the expression of all of SOD, catalase, and TFAM in MP3 and MP5 groups was decreased on WB as compared with C group, while in MP14 group a tendency to improvement was seen. Accordingly, steroid-associated mitochondrial injury and redox failure are concluded to be important elements implicated in the pathogenesis of osteonecrosis. PMID:29483810

Cabrera-Muñoz et al., show that progesterone participates in the regulation of human brain tumors growth. The contribution of Martocchia suggests that sex steroid receptor modulating drugs provide new therapeutic approaches to autoimmune diseases. The role of sex steroid participation in the differentiation of stem cells to neurones is discussed by I. Velasco. Pérez-Torres and collaborators demonstrate that sex steroids play an important role in the appearance and development of renal diseases and the metabolic syndrome, the new epidemics of our century. Paris and Frye hypthetize that gestational stress, have effects on cognitive performance and/or neuronal integrity in the fetus, and that exposure to variable stress during gestation can perturb cognitive performance, concomitant with dendrite development in hippocampus and diencephalon. Muñoz-Cruz et al. thoroughly review the growing body of evidence that shows reciprocal relationship between sex steroids and the immune system, and conclude that understanding the mechanisms of action of sex steroids on immune cells is important for further progress in the development of novel therapies for chronic diseases associated to immune dysregulation. Besides, the effects of sexual steroids on pancreatic function and diabetes are reviewed by Morimoto et al. Yanes et al. review some of the contradictions raised in the context of the recently proposed critical period hypothesis, which takes into account the frame-time after cessation of ovarian function. Finally, another vey intetresting aspect of the non-reproductive effects of sex-steroids, is the related to some cognition-related aspects, which is reviewed by Picazo et al.

The goals of the AIPS fault injection study were: (1) to present the fault injection study components addressing the AIPS validation objective; (2) to obtain feedback for fault removal from the design implementation; (3) to obtain statistical data regarding fault detection, isolation, and reconfiguration responses; and (4) to obtain data regarding the effects of faults on system performance. The parameters are described that must be varied to create a comprehensive set of fault injection tests, the subset of test cases selected, the test case measurements, and the test case execution. Both pin level hardware faults using a hardware fault injector and software injected memory mutations were used to test the system. An overview is provided of the hardware fault injector and the associated software used to carry out the experiments. Detailed specifications are given of fault and test results for the I/O Network and the AIPS Fault Tolerant Processor, respectively. The results are summarized and conclusions are given.

    Anabolic steroid abuse adversely affects the endocrine system, blood lipids, and the liver, but renal injury has not been described. We identified an association of focal segmental glomerulosclerosis (FSGS) and proteinuria in a cohort of 10 bodybuilders (six white and four Hispanic; mean body mass index 34.7) after long-term abuse of anabolic steroids. The clinical presentation included proteinuria (mean 10.1 g/d; range 1.3 to 26.3 g/d) and renal insufficiency (mean serum creatinine 3.0 mg/dl; range 1.3 to 7.8 mg/dl); three (30%) patients presented with nephrotic syndrome. Renal biopsy revealed FSGS in nine patients, four of whom also had glomerulomegaly, and glomerulomegaly alone in one patient. Three biopsies revealed collapsing lesions of FSGS, four had perihilar lesions, and seven showed ≥40% tubular atrophy and interstitial fibrosis. Among eight patients with mean follow-up of 2.2 yr, one progressed to ESRD, the other seven received renin-angiotensin system blockade, and one also received corticosteroids. All seven patients discontinued anabolic steroids, leading to weight loss, stabilization or improvement in serum creatinine, and a reduction in proteinuria. One patient resumed anabolic steroid abuse and suffered relapse of proteinuria and renal insufficiency. We hypothesize that secondary FSGS results from a combination of postadaptive glomerular changes driven by increased lean body mass and potential direct nephrotoxic effects of anabolic steroids. Because of the expected rise in serum creatinine as a result of increased muscle mass in bodybuilders, this complication is likely underrecognized. PMID:19917783

    Little is known about the role of the endocrine system in financial decision-making. Here, we survey research on steroid hormones and their cognitive effects, and examine potential links to trader performance in the financial markets. Preliminary findings suggest that cortisol codes for risk and testosterone for reward. A key finding of this endocrine research is the different cognitive effects of acute versus chronic exposure to hormones: acutely elevated steroids may optimize performance on a range of tasks; but chronically elevated steroids may promote irrational risk-reward choices. We present a hypothesis suggesting that the irrational exuberance and pessimism observed during market bubbles and crashes may be mediated by steroid hormones. If hormones can exaggerate market moves, then perhaps the age and sex composition among traders and asset managers may affect the level of instability witnessed in the financial markets.

    To report a rare outbreak of toxic anterior segment syndrome (TASS) in 4 patients who underwent vitrectomy with silicone oil injection. Review of the medical charts of all patients who underwent surgery in the operating theater of our department during a 10-day period in May 2011. We report on 4 patients who developed TASS after vitrectomy with silicone oil injection. The clinical presentation was typical of TASS, and different from the anterior chamber reaction that may occur after silicone oil injection. All cases were treated effectively with topical steroids, and the outbreak stopped after the silicone oil batch was exchanged. We discuss the possible mechanisms for this unusual TASS outbreak, and suggest the silicone oil as its cause.

    To conduct a systematic review and meta-analysis on the efficacy of oral non-steroidal anti-inflammatory drugs for rotator cuff tendinopathy. Systematic review. A literature search was conducted in 4 databases for randomized controlled trials published until 05/2013, comparing the efficacy of oral anti-inflammatory drugs to any other intervention. Studies characteristics were extracted using a standardized form and the methodological quality was evaluated. Results were summarized qualitatively or quantitatively. The mean methodological score of the 12 included studies was 53.6 ± 8.8%. The majority of studies included acute cases and were underpowered to detect differences in adverse events. Compared to a placebo, oral non-steroidal anti-inflammatory drugs were found to provide short-term pain relief (pooled mean difference: -2.69; 95% confidence interval: -1.96 to -3.41) but not function. Oral anti-inflammatory- drugs and corticosteroids injections have similar short-term efficacy in terms of pain reduction as well as in function (pooled standardized mean difference: 0.09; 95% confidence interval: -0.25 to 0.44). Low to moderate grade evidence exists regarding the efficacy of non-steroidal anti-inflammatory drugs for rotator cuff tendinopathy. Oral anti-inflammatory drugs are effective in reducing short-term pain but not function. In terms of pain and function, oral anti-inflammatory drugs in the short term are as effective as corticosteroid injections.

    An injectable, self-healing hydrogel (≈1.5 kPa) is developed for healing nerve-system deficits. Neurosphere-like progenitors proliferate in the hydrogel and differentiate into neuron-like cells. In the zebrafish injury model, the central nervous system function is partially rescued by injection of the hydrogel and significantly rescued by injection of the neurosphere-laden hydrogel. The self-healing hydrogel may thus potentially repair the central nervous system. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Steroid receptor coactivators are necessary for efficient transcriptional regulation by ligand-bound nuclear receptors, including estrogen and androgen receptors. SRC-2 modulates estrogen- and progesterone-dependent sexual behavior in female rats but its implication in the control of male sexual behavior has not been studied to our knowledge. We cloned and sequenced the complete quail SRC-2 transcript and showed by semi-quantitative PCR that SRC-2 expression is nearly ubiquitous, with high levels of expression in the kidney, cerebellum and diencephalon. Real time quantitative PCR did not reveal any differences between intact males and females the medial preoptic nucleus (POM), optic lobes and cerebellum. We next investigated the physiological and behavioral role of this coactivator using in vivo antisense oligonucleotide (AS) techniques. Daily injections in the third ventricle at the level of the POM of locked nucleic acid antisense targeting SRC-2 significantly reduced the expression of testosterone-dependent male-typical copulatory behavior but no inhibition of one aspect of the appetitive sexual behavior was observed. The volume of POM, defined by aromatase-immunoreactive cells, was markedly decreased in animals treated with AS as compared to controls. These results demonstrate that SRC-2 plays a prominent role in the control of steroid-dependent male sexual behavior and its associated neuroplasticity in Japanese quail. PMID:21854393

    To examine the role of oral steroid therapy in the treatment of nondiabetic cases of acute nonarteritic anterior ischemic optic neuropathy (NAAION). Randomized double-blind clinical trial. Thirty-eight patients with acute nondiabetic NAAION divided into 2 arms of 19 patients each. One arm constituted the cases and the other constituted the controls. Cases received oral steroid therapy and were designated the steroid group, whereas controls received placebo and were designated the nonsteroid group. Best-corrected visual acuity (BCVA), visual evoked response (VER), and OCT were performed at baseline, 1 month, 3 months, and 6 months after recruitment into the trial. Best-corrected visual acuity, VER, and retinal nerve fiber layer changes on OCT. Both groups showed significant improvement in BCVA, VER latency, and resolution of disc edema on OCT parameters over 6 months. Final outcome showed no statistically significant difference with regard to visual acuity, although VER was better in the steroid group (P = 0.011). Best-corrected visual acuity, VER amplitude, and VER latency (P = 0.02, P = 0.02, and P = 0.04, respectively) showed a greater percentage improvement in the steroid group, which also saw a faster resolution of disc edema on OCT (1-month follow-up). Oral steroids in acute NAAION did not improve the visual acuity significantly at 6 months. However, they improved resolution of disc edema significantly and enabled a greater improvement in VER parameters. This subtle benefit of oral steroids in NAAION is clinically unimportant and does not provide support for its use. Copyright © 2018 American Academy of Ophthalmology. Published by Elsevier Inc.

    In the last couple of decades fungal infections have become a significant clinical problem. A major interest into fungal steroid action has been provoked since research has proven that steroid hormones are toxic to fungi and affect the host/fungus relationship. Steroid hormones were found to differ in their antifungal activity in ascomycetous fungi Hortaea werneckii, Saccharomyces cerevisiae and Aspergillus oryzae. Dehydroepiandrosterone was shown to be the strongest inhibitor of growth in all three varieties of fungi followed by androstenedione and testosterone. For their protection, fungi use several mechanisms to lower the toxic effects of steroids. The efficiency of biotransformation in detoxification depended on the microorganism and steroid substrate used. Biotransformation was a relatively slow process as it also depended on the growth phase of the fungus. In addition to biotransformation, steroid extrusion out of the cells contributed to the lowering of the active intracellular steroid concentration. Plasma membrane Pdr5 transporter was found to be the most effective, followed by Snq2 transporter and vacuolar transporters Ybt1 and Ycf1. Proteins Aus1 and Dan1 were not found to be involved in steroid import. The research of possible targets of steroid hormone action in fungi suggests that steroid hormones inhibit ergosterol biosynthesis in S. cerevisiae and H. werneckii. Results of this inhibition caused changes in the sterol content of the cellular membrane. The presence of steroid hormones most probably causes the degradation of the Tat2 permease and impairment of tryptophan import. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Allergic rhinitis is a global health problem, and its prevalence rate and socioeconomic burden continue to increase. Intranasal steroid (INS) is the first treatment choice in the majority of patients, because of its ability to effectively control allergic symptoms. However, patients and clinicians are concerned about the potential adverse effects of prolonged INS use. We performed to review for evaluating systemic and local safety of INS use, by searching MEDLINE, EMBASE, and Cochrane Library database for identification of relevant articles. In the present study, the systemic bioavailabilities of several commercially available INSs were researched, and then systemic safeties were reviewed with focus on suppression of the hypothalamus-pituitary-adrenal axis and their effects on pediatric growth. In addition, local adverse effects, such as, epistaxis and nasal septal perforation, were investigated. Finally, the authors proposed some techniques in order to avoid these complications. INSs offer a safe, effective means of treating allergic rhinitis in the short- and long-term with no or minimal adverse systemic and local effects.

    All vertebrate embryos are exposed to maternally derived steroids during development. In placental vertebrates, metabolism of maternal steroids by the placenta modulates embryonic exposure, but how exposure is regulated in oviparous vertebrates is less clear. Recent work in oviparous vertebrates has demonstrated that steroids are not static molecules, as they can be converted to more polar steroid sulfates by sulfotransferase enzymes. Importantly, these steroid sulfates can be converted back to the parent compound by the enzyme steroid sulfatase (STS). We investigated when and where STS was present during embryonic development in the red-eared slider turtle, Trachemys scripta We report that STS is present during all stages of development and in all tissues we examined. We conclude that STS activity may be particularly important for regulating maternal steroid exposure in oviparous vertebrates. © 2017. Published by The Company of Biologists Ltd.

    A randomized, double-blind, active-controlled trial. To assess the effectiveness of cervical interlaminar epidural injections of local anesthetic with or without steroids for the management of axial or discogenic pain in patients without disc herniation, radiculitis, or facet joint pain. Cervical discogenic pain without disc herniation is a common cause of suffering and disability in the adult population. Once conservative management has failed and facet joint pain has been excluded, cervical epidural injections may be considered as a management tool. Despite a paucity of evidence, cervical epidural injections are one of the most commonly performed nonsurgical interventions in the management of chronic axial or disc-related neck pain. One hundred and twenty patients without disc herniation or radiculitis and negative for facet joint pain as determined by means of controlled diagnostic medial branch blocks were randomly assigned to one of the 2 treatment groups. Group I patients received cervical interlaminar epidural injections of local anesthetic (lidocaine 0.5%, 5 mL), whereas Group II patients received 0.5% lidocaine, 4 mL, mixed with 1 mL or 6 mg of nonparticulate betamethasone. The primary outcome measure was ≥ 50% improvement in pain and function. Outcome assessments included numeric rating scale (NRS), Neck Disability Index (NDI), opioid intake, employment, and changes in weight. Significant pain relief and functional improvement (≥ 50%) was present at the end of 2 years in 73% of patients receiving local anesthetic only and 70% receiving local anesthetic with steroids. In the successful group of patients, however, defined as consistent relief with 2 initial injections of at least 3 weeks, significant improvement was illustrated in 78% in the local anesthetic group and 75% in the local anesthetic with steroid group at the end of 2 years. The results reported at the one-year follow-up were sustained at the 2-year follow-up. Cervical interlaminar epidural

    2018-04-01

    The cryogenic engine has received increasing attention due to its promising potential as a zero-emission engine. In this study, a new robust liquid nitrogen injection system was commissioned and set up to perform high-pressure injections into an open vessel. The system is used for quasi-steady flow tests used for the characterisation of the direct injection process for cryogenic engines. An electro-hydraulic valve actuator provides intricate control of the valve lift, with a minimum cycle time of 3 ms and a frequency of up to 20 Hz. With additional sub-cooling, liquid phase injections from 14 to 94 bar were achieved. Results showed an increase in the injected mass with the increase in pressure, and decrease in temperature. The injected mass was also observed to increases linearly with the valve lift. Better control of the injection process, minimises the number of variables, providing more comparable and repeatable sets of data. Implications of the results on the engine performance were also discussed.

  19. Endogenous steroid profiling in the athlete biological passport.

    The Athlete Biological Passport (ABP) is an individual electronic document that collects data regarding a specific athlete that is useful in differentiating between natural physiologic variations of selected biomarkers and deviations caused by artificial manipulations. A subsidiary of the endocrine module of the ABP, that which here is called Athlete Steroidal Passport (ASP), collects data on markers of an altered metabolism of endogenous steroidal hormones measured in urine samples. The ASP aims to identify not only doping with anabolic-androgenic steroids, but also most indirect steroid doping strategies such as doping with estrogen receptor antagonists and aromatase inhibitors. Development of specific markers of steroid doping, use of the athlete's previous measurements to define individual limits, with the athlete becoming his or her own reference, the inclusion of heterogeneous factors such as the UDPglucuronosyltransferase B17 genotype of the athlete, the knowledge of potentially confounding effects such as heavy alcohol consumption, the development of an external quality control system to control analytical uncertainty, and finally the use of Bayesian inferential methods to evaluate the value of indirect evidence have made the ASP a valuable alternative to deter steroid doping in elite sports. The ASP can be used to target athletes for gas chromatography/combustion/ isotope ratio mass spectrometry (GC/C/IRMS) testing, to withdraw temporarily the athlete from competing when an abnormality has been detected, and ultimately to lead to an antidoping infraction if that abnormality cannot be explained by a medical condition. Although the ASP has been developed primarily to ensure fairness in elite sports, its application in endocrinology for clinical purposes is straightforward in an evidence-based medicine paradigm.

    Root canal treatment, including obturation with gutta-percha and a zinc oxide and eugenol sealer, was conducted, under general anesthesia, on the canine teeth of 12 young ferrets. Six of the ferrets were given 0.5 mg/kg dexamethasone daily. Three months after the root canal treatment, under general anesthesia, the animals were perfused with fixative and the canine periapical tissues prepared for histological examination. The extent of periapical inflammation was measured and the degree of neural sprouting in the periodontal and subapical regions estimated. Periapical lesions in steroid-treated animals were 30% of the size of those in untreated animals. Innervation density in the subapical region of the steroid-treated animals was lower than that in the animals who did not receive steroids and not significantly different from controls. Reduction in periapical inflammation induced by systemic steroids is accompanied by a reduction in neural sprouting.

    To determine whether the intraarticular (IA) dose of triamcinolone hexacetonide (TH) or triamcinolone acetonide (TA) influences time to relapse among patients with juvenile idiopathic arthritis (JIA). The primary endpoint variable was the time to relapse of arthritis in the affected joint after an intraarticular (IA) injection. A relapse was defined as the reoccurrence of active arthritis in the injected joint. Analysis was carried out including only the first IA joint injection for each patient. Further analysis was conducted including the first knee injection alone. A separate analysis within the IA corticosteroid groups was performed using the Spearman rank coefficient, to determine if dose of IA steroid affected time to relapse. Records from 186 patients with JIA (145 females, 41 males) injected with either TH or TA were collected from January 1995 through December 2003. All subjects were followed for a minimum of 15 months from the time of IA injection. Of the 794 joint injections, 422 (53.1%) were injected with TH and 372 (46.9%) with TA. There were 111 first joint injections (all joints) with TH and 70 with TA. There were 89 first joint injections (knee only) with TH and 56 with TA. TH proved more effective than TA with respect to the time to relapse for first injection into all joints (10.47 ± 0.42 mo vs 8.66 ± 0.59 mo; p < 0.001), and for first injections into knee only (11.04 ± 0.44 vs 8.99 ± 0.65 mo; p < 0.001). IA doses ranged from 0.4 to 4 mg/kg (mean 1.56 ± 0.76) for TH and from 0.5 to 8 mg/kg (mean 2.54 ± 1.74) for TA. There was no correlation between time to relapse and dose of either TH and TA (r = 0.1, p > 0.5). There was no correlation between time to relapse and sex, duration of illness, age of patient, concurrent medications, or subtype of JIA. In a larger dataset (794 injections) we have confirmed our previous findings (227 injections) that TH is a more effective IA corticosteroid than TA. In this much larger data analysis, dose of IA

    Drug-induced and indeterminate acute liver failure (ALF) might be due to an autoimmune-like hepatitis that is responsive to corticosteroid therapy. The aim of this study was to evaluate whether corticosteroids improve survival in fulminant autoimmune hepatitis, drug-induced, or indeterminate ALF, and whether this benefit varies according to the severity of illness. We conducted a retrospective analysis of autoimmune, indeterminate, and drug-induced ALF patients in the Acute Liver Failure Study Group from 1998-2007. The primary endpoints were overall and spontaneous survival (SS, survival without transplant). In all, 361 ALF patients were studied, 66 with autoimmune (25 steroids, 41 no steroids), 164 with indeterminate (21 steroids, 143 no steroids), and 131 with drug-induced (16 steroids, 115 no steroids) ALF. Steroid use was not associated with improved overall survival (61% versus 66%, P = 0.41), nor with improved survival in any diagnosis category. Steroid use was associated with diminished survival in certain subgroups of patients, including those with the highest quartile of the Model for Endstage Liver Disease (MELD) (>40, survival 30% versus 57%, P = 0.03). In multivariate analysis controlling for steroid use and diagnosis, age (odds ratio [OR] 1.37 per decade), coma grade (OR 2.02 grade 2, 2.65 grade 3, 5.29 grade 4), MELD (OR 1.07), and pH < 7.4 (OR 3.09) were significantly associated with mortality. Although steroid use was associated with a marginal benefit in SS overall (35% versus 23%, P = 0.047), this benefit did not persistent in multivariate analysis; mechanical ventilation (OR 0.24), MELD (OR 0.93), and alanine aminotransferase (1.02) were the only significant predictors of SS. Corticosteroids did not improve overall survival or SS in drug-induced, indeterminate, or autoimmune ALF and were associated with lower survival in patients with the highest MELD scores. © 2013 by the American Association for the Study of Liver Diseases.

    High-speed motion pictures were taken of individual fuel sprays from a pump injection system. The changes in the spray-tip penetration with changes in the pump speed, injection-valve opening and closing pressures, discharge-orifice area, injection-tube length and diameter, and pump throttle setting were measured. In addition, the effects of the variables on the time lag and duration of injection can be controlled by the dimensions of the injection tube, the area of the discharge orifice, and the injection-valve opening and closing pressures.

    The purpose of the study was to evaluate the accuracy of injections into the carpal tunnel using three different portals in cadavers, and to define safe guidelines. In this study, 150 wrists of 75 cadavers (54 male, 21 female) were included. To compare three injection sites, 50 wrists of 25 cadavers were used for each technique; we used 23 gauge needles, and acrylic dye. The first injection technique: the needle was inserted 1cm proximal to the wrist crease and directed distally by roughly 45 in an ulnar direction through the flexor carpi radialis tendon. The second injection technique: the needle was inserted into the carpal tunnel from a point just ulnar to the palmaris longus tendon and 1cm proximal to the wrist crease. The third injection technique: the needle was inserted just distal to the distal skin crease of the wrist in line with the fourth ray. The first injection technique gave the highest accuracy rate, and this was also the safest injection site. Median nerve injuries caused by injection was seen mostly with the second technique. Although a steroid injection may provide symptomatic relief in patients with carpal tunnel syndrome, the median nerve and other structures in the carpal tunnel are at risk of injury. Because of that, the injection should be given using the correct technique by physicians skilled in carpal tunnel surgery.

    Prospective cohort study. To report the clinical course of patients with MRI-confirmed lumbar disc herniation-related radicular noncentralizing pain who received transforaminal epidural steroid injections (TESIs) and mechanical diagnosis and therapy (MDT). Noncentralizing symptoms in patients with lumbar disc herniation are associated with poor outcome. Commonly used treatments for these patients include TESIs and MDT. No study has evaluated the outcome of combining both strategies. Consecutive candidates for herniated lumbar disc surgery with noncentralizing chronic pain were eligible. Patients received TESIs followed by MDT. The primary outcomes were pain severity in the leg, disability (Roland-Morris Disability Questionnaire for Sciatica), and global perceived effect (GPE). Outcomes were measured at baseline, discharge, and 12 months. Linear mixed-models and McNemar's tests were used to analyze outcome data. Sixty-nine patients receive TESIs. After TESIs, symptoms were resolved completely in 11 patients (16%). In these patients, symptom resolution was maintained at 12 months. A second subgroup of 32 patients (46%) reported significantly less pain after TESIs and showed centralization with MDT reassessment (significant reductions in leg pain and disability [P < 0.001]) and a satisfaction rate of 90% at 12 months. A third subgroup of 11 patients (16%) reported significantly less pain after TESIs but still showed noncentralization with MDT reassessment (significant reductions in leg pain and disability [P < 0.05] and a satisfaction rate of 50% at 12 months). A fourth subgroup of 15 patients (22%) did not respond on TESIs and received an operative intervention. The results indicate that a course of TESIs followed by MDT may be able to avoid surgery in a substantial proportion of candidates for herniated lumbar disc surgery. Wiley Periodicals, Inc.

    While effects of different steroids on the gene expression and regulation are well established, it is proven that steroids can also exert rapid non-genomic actions in several tissues and cells. In most cases, these non-genomic rapid effects of steroids are actually due to intracellular mobilization of Ca(2+)- and other ions suggesting that Ca(2+) channels are involved in such effects. Transient Receptor Potential (TRP) ion channels or TRPs are the largest group of non-selective and polymodal ion channels which cause Ca(2+)-influx in response to different physical and chemical stimuli. While non-genomic actions of different steroids on different ion channels have been established to some extent, involvement of TRPs in such functions is largely unexplored. In this review, we critically analyze the literature and summarize how different steroids as well as their metabolic precursors and derivatives can exert non-genomic effects by acting on different TRPs qualitatively and/or quantitatively. Such effects have physiological repercussion on systems such as in sperm cells, immune cells, bone cells, neuronal cells and many others. Different TRPs are also endogenously expressed in diverse steroid-producing tissues and thus may have importance in steroid synthesis as well, a process which is tightly controlled by the intracellular Ca(2+) concentrations. Tissue and cell-specific expression of TRP channels are also regulated by different steroids. Understanding of the crosstalk between TRP channels and different steroids may have strong significance in physiological, endocrinological and pharmacological context and in future these compounds can also be used as potential biomedicine.

    In recent years, the potential for anabolic steroid abuse in equine sports has increased due to the growing availability of designer steroids. These compounds are readily accessible online in 'dietary' or 'nutritional' supplements and contain steroidal compounds which have never been tested or approved as veterinary agents. They typically have unusual structures or substitution and as a result may pass undetected through current anti-doping screening protocols, making them a significant concern for the integrity of the industry. Despite considerable focus in human sports, until recently there has been limited investigation into these compounds in equine systems. To effectively respond to the threat of designer steroids, a detailed understanding of their metabolism is needed to identify markers and metabolites arising from their misuse. A summary of the literature detailing the metabolism of these compounds in equine systems is presented with an aim to identify metabolites suitable for incorporation into screening protocols by anti-doping laboratories. The future of equine anti-doping research is likely to be guided by the incorporation of alternate testing matrices into routine screening, the improvement of in vitro technologies that can mimic in vivo equine metabolism, and the improvement of instrumentation or analytical methods that allow for the development of untargeted screening, and metabolomics approaches for use in anti-doping screening protocols.

    a fuel injection system for gas turbines is described including a pair of high pressure pumps. The pumps provide fuel and a carrier fluid such as air at pressures above the critical pressure of the fuel. A supercritical mixing chamber mixes the fuel and carrier fluid and the mixture is sprayed into a combustion chamber. The use of fuel and a carrier fluid at supercritical pressures promotes rapid mixing of the fuel in the combustion chamber so as to reduce the formation of pollutants and promote cleaner burning.

    Many of the long-term complications in lung transplantations are secondary effects of immunosuppression. Corticosteroids are partially responsible for the development of osteoporosis, raised blood pressure, diabetes, muscular disorders, gastric ulcers, and other conditions. We analyzed the long-term result of steroid withdrawal in our lung transplant recipients. When respiratory function stabilized, to avoid secondary effects, steroid treatment was withdrawn in 34 of the 375 lung transplant patients in our centers We evaluated the characteristics of the donors and recipients, their compatibility, the pre, and post-steroid withdrawal complications, and type of immunosuppressant. The mean age of patients was 42 +/- 7 years and of donors, 25 +/- 9 years. The primary diseases were: 15 emphysema, six pulmonary fibrosis, 10 cystic fibrosis, and three primary pulmonary hypertension. Twenty seven patients had double lung transplants and seven single lung. The mean steroid withdrawal period was 881 +/- 237 days posttransplantation. The most frequent treatment regimen at the time of steroid withdrawal was cyclosporine, azathioprine, and minimal steroid doses. Six recipients had to be restarted on steroids one patient who required a kidney transplant, three cases due to an infectious process with a differential diagnosis of rejection, and two cases due to loss of FEV1 (forced expiratory volume in 1 s), suggestive of chronic rejection. There was an improvement in blood pressure in five patients, in plasma cholesterol and triglyceride levels in eight patients, and insulin withdrawal in two diabetic patients. Steroid treatment may be suspended 2 to 3 years, posttransplant in selected lung transplant recipients. The usual patient profile shows few rejection episodes with cyclosporine and azathioprine immunosuppression. What is notable is the low mean age of donors. Close clinical monitoring and lung function testing are of major importance in the weeks following steroid

    Data indicates that some steroid derivatives may induce changes on glucose levels; nevertheless, data are very confusing. Therefore, more pharmacological data are needed to characterize the activity induced by the steroid derivatives on glucose levels. The aim of this study was to synthesize a new steroid derivative for evaluate its hypoglycemic activity. The effects of steroid derivative on glucose concentration were evaluated in a diabetic animal model using glibenclamide and metformin as controls. In addition, the pregnenolone-dihydrotestosterone conjugate was bound to Tc-99m using radioimmunoassay methods, to evaluate the pharmacokinetics of the steroid derivative over time. The results showed that the pregnenolone-dihydrotestosterone conjugate induces changes on the glucose levels in similar form than glibenclamide. Other data showed that the biodistribution of Tc-99m-steroid derivativein brain was higher in comparison with spleen, stomach, intestine liver and kidney. In conclusion, the pregnenolone-dihydrotestosterone conjugate exerts hypoglycemic activity and this phenomenon could depend of its physicochemical properties which could be related to the degree of lipophilicity of the steroidderivative.

    Estrogens, acting via estrogen receptor (ER) play key roles in growth, differentiation and gene regulation in the reproductive, central nervous and skeletal systems. ER-mediated gene transcription contributes to the development and spread of breast, uterine, and liver cancer. Steroid receptor coactivator-1a (SRC1a) belongs to the P160 family of coactivators, which is the best known of the many coactivators implicated in ER-mediated transactivation. Binding of full-length P160 coactivators to steroid receptors has been difficult to investigate in vitro. This chapter details how to investigate the interaction of SRC1a with ER using the fluorescence anisotropy/polarization microplate assay (FAMA). PMID:23436375

    Corticosteroids are effective rescue therapies for patients with inflammatory bowel disease (IBD), but have significant side effects, which may be amplified in the growing population of elderly patients with IBD. We aimed to compare the use of steroids and steroid-sparing therapies (immunomodulators and biologics) and rates of complications among elderly (≥65) and younger patients in a national cohort of veterans with IBD. We used national Veterans Health Administrative data to conduct a retrospective study of veterans with IBD between 2002 and 2010. Medications and the incidence of complications were obtained from the Veterans Health Administrative Decision Support Systems. Multivariate logistic regression accounting for facility-level clustering was used to identify predictors of use of steroid-sparing medications. We identified 30,456 veterans with IBD. Of these, 94% were men and 40% were more than 65, and 32% were given steroids. Elderly veterans were less likely to receive steroids (23.8% versus 38.3%, P < 0.001) and were less likely to be prescribed steroid-sparing medications (25.5% versus 46.9%, respectively, P < 0.001). In multivariate analysis controlling for sex, age <65 (odds ratio, 2.19; 95% CI, 1.54-3.11) and gastroenterology care (odds ratio, 8.42; 95% CI, 6.18-11.47) were associated with initiation of steroid-sparing medications. After starting steroids, fracture rates increased in the elderly patients with IBD, whereas increases in venous thromboembolism and infections after starting steroids affected both age groups. Elderly veterans are less likely to receive steroids and steroid-sparing medications than younger veterans; elderly patients exposed to steroids were more likely to have fractures than the younger population.

    To evaluate the effects of oral steroids alone or followed by intranasal steroids versus watchful waiting on the resolution of otitis media with effusion in children aged 2-11 years. A total of 290 children with bilateral otitis media with effusion were assigned to 3 groups: group A was treated with oral steroids followed by intranasal steroids, group B was treated with oral steroids alone and group C was managed with watchful waiting. Patients were evaluated with audiometry and tympanometry. The complete resolution rates of otitis media with effusion were higher in groups A and B than in group C at six weeks. There were no significant differences in otitis media with effusion resolution rates between the groups at three, six and nine months. Oral steroids lead only to a quick resolution of otitis media with effusion, with no long-term benefits. There was no benefit of using intranasal steroids in the management of otitis media with effusion.

    A retrospective case-control study. The aim of this study was to determine the effect of retropharyngeal steroids on postoperative dysphagia scores and clinical outcomes following multilevel anterior cervical discectomy and fusion (ACDF). Dysphagia is a well-known complication following ACDF surgery and increased rates of dysphagia are seen with increased levels of surgery. Retropharyngeal steroids have been shown to decrease painful swallowing and prevertebral soft tissue (PSTS) swelling in 1- and 2-level anterior cervical surgery. A retrospective review of 44 patients undergoing multilevel (2-, 3-, 4-level) ACDF. Twenty-two patients who received retropharyngeal steroids (methylprednisone) placed on a collagen sponge at the time of surgery were compared with a matched cohort of controls who did not receive local steroids. Postoperative day 1 and 6-week radiographs were analyzed for differences in PSTS. Clinical outcomes were measured pre-operatively, 6 weeks, and 3 months postoperatively utilizing the Neck Disability Index (NDI), the Bazaz-Yoo Dysphagia Scoring System, and Eat Assessment Tool (EAT-10). Significant improvement in dysphagia scores were seen utilizing both outcome measures. Bazaz-Yoo scores were significantly better at both 6 weeks and 3 months in patients receiving local steroids compared with controls (P = 0.008 and P = 0.022, respectively). EAT-10 showed similar improvement of the steroid group versus control at 6 weeks and 3 months (P = 0.067 and P = 0.012, respectively). A trend toward decreased PSTS was found with locally delivered steroids on initial postoperative radiographs (P = 0.07), but was no longer evident at 6 weeks. NDI, although improved from pre-operative scores, failed to demonstrate significant differences between groups. No differences in length of stay or complications were observed between the groups. The use of retropharyngeal steroids resulted in decreased rates of dysphagia following multilevel ACDF

    To report on the management of five cases of pyomyositis in athletes after the use of anabolic steroids. Over the past 10 years, five cases of athletes who developed pyomyositis after using anabolic steroids were attended at the Sports Trauma Center (CETE), EPM-UNIFESP. All the patients were diagnosed clinically and through laboratory and imaging tests. Surgical treatment was carried out (with collection of material for culturing) and antibiotic therapy was administered. In four cases, the injection sites were in the upper limbs and in one case, in the gluteus muscles bilaterally as well as in the upper limbs. In all five cases, occurrences of leukocytosis and neutrophilia were observed in the hemogram. After debridement, the germs of normal skin (S. aureus and S. viridans) were found in cultures on the secretions. Demarcation of the abscess and examination of the muscle plane in which the abscess was located were performed using ultrasound and magnetic resonance imaging. All the patients responded to broad-spectrum antibiotic therapy. Two cases required more than one surgical procedure because of the appearance of more than one abscess site with different evolution times. The use of anabolic steroids by some athletes may have grave consequences. Rapid, energetic and multidisciplinary intervention is necessary in such cases in order to avoid undesirable results. The right treatment healed the athletes completely, and they returned to their sports at the same level.

    High-performance liquid chromatography (HPLC)-UV and HPLC-Mass Spectrometry (MS) methods were developed for the quantitative analysis of the family of Hoodia gordonii steroid glycosides with appetite suppressing properties in dried plant material, in purified and enriched extracts and in various prototype food-products fortified with H. gordonii extracts. For solid materials, e.g. dried plants or for non-fatty foods, extraction of the steroid glycosides is performed using methanol. For products where the steroid glycosides are present in an oil matrix, direct injection of the oil after dilution in tetrahydrofuran is applied. The HPLC separation is performed on an octyl-modified reversed-phase column in the gradient mode with UV detection at lambda = 220 nm. Quantification is performed against an external calibration line prepared using either one of the pure steroid glycosides or geranyl-tiglate. Short- and long-term repeatabilities of the methods are better than 3 and 6%, respectively. Recoveries are better than 85%, even in the analysis of the least abundant steroid glycosides in a complex yoghurt drink. Linearity is better than 3-4 orders of magnitude and the detection limits are below approximately 2 microg g(-1) for the individual steroid glycosides in dried plant material and food products. HPLC-MS is used to confirm that the steroid glycosides contain the characteristic steroid core, the carbohydrate chain and the tigloyl group.

    Age-related differences in the expression of inflammatory cytokines in the inner ear may contribute to the development of age-related hearing loss (ARHL). ARHL is characterized by tissue remodeling, ischemia, ion homeostasis, and inflammation. Steroid therapy is an otoprotective strategy that likely acts by reducing inflammation. We examined age-related changes in cytokine gene expression in the cochlea of the BALB/cJ mouse model of premature ARHL after systemic or intratympanic steroid delivery. 'Young' (2.5-3 months) and 'Old' (5-9 months) mice were treated with dexamethasone or fludrocortisone administered either orally or intratympanically. Cytokine gene expression in cochlear RNA was analyzed using prefabricated cDNA arrays. Old groups were compared to Young groups to identify age-related changes. Down-regulation of a cytokine associated with bone remodeling (SPP1) was observed in the untreated Old group. Numerous genes were up- or down-regulated by more than twofold by steroid treatment, including proinflammatory interleukins (IL-16) and anti-inflammatory cytokines.

    Background and Aims: Diabetes affects peripheral and central neurons causing paresthesia, allodynia, hyperalgesia, and spontaneous pain. However, the effect of diabetes on response to epidural steroid injection (ESI) remains unknown. We hypothesized that diabetic patients receiving ESI will have different pain scores compared to nondiabetic patients. We tested a secondary hypothesis that pain reduction differs at different levels of hemoglobin A1c (HbA1c) for patients with diabetes. Material and Methods: Data from 284 consecutive patients given ESIs for radiculopathy were obtained via a manual review of electronic medical records. We initially compared diabetic and nondiabetic groups with respect to balance on baseline demographic and morphometric characteristics. Next, a linear regression model was developed to evaluate the association between existing diabetes and postinjection reduction in pain scores. And finally, we univariably characterized the association between HbA1c and pain reduction. Results: After exclusion of nine patients, 275 patients were analysed, including 55 (20%) who were diabetic. Pain reduction after ESI was comparable in diabetic and nondiabetic patients (Wald test P = 0.61). The degree of pain reduction generally decreased with the level of HbA1c until reaching HbA1c levels of approximately 7.5%, after which point it stayed fairly constant. Conclusion: There was no difference in pain reduction after ESIs comparing diabetic with nondiabetic patients; however, for diabetic patients, pain reduction may decrease with uncontrolled diabetes determined by high HbA1c values, thus suggesting pain physicians to take an active role in guiding their patients to have their blood glucose levels better regulated to improve outcomes of their ESIs.

    Steroids are often used as medical therapy for active thyroid eye disease (TED). While high-dose steroids have been shown to be effective in reducing the severity of TED symptoms, the side effects of steroids can be severe. As the pathogenesis of TED is thought to involve the upregulation of proinflammatory cytokines, including tumor necrosis factor-α (TNF-α), it has been postulated that anti-TNF agents may be used as steroid-sparing agents in the treatment of TED. This retrospective study was conducted to examine the efficacy of adalimumab, a subcutaneously administered TNF-α antagonist, in treating the inflammatory symptoms of active TED. All patients in the inflammatory phase of TED who were treated with adalimumab at the Jules Stein Eye Institute over a 2-year period were reviewed. Data concerning visual acuity, optic nerve function, extraocular motility restriction, binocular visual fields, and proptosis were extracted from patient charts. Clinical photographs from baseline and 3-month follow-up visits were reviewed by masked orbital specialists. Each photograph was graded on the severity of conjunctival injection, chemosis, eyelid erythema, and eyelid edema on a scale from 1 to 4. An inflammatory score was calculated as the sum of these 4 elements. Groups were compared using paired t tests. Six of 10 patients showed a decrease in inflammatory score while on adalimumab, whereas 3 showed an increase and 1 stayed the same. One patient experienced a significant complication (hospital admission for sepsis). Eight patients received concomitant tapering steroids during the first 6 weeks of therapy as the adalimumab reached maximum efficacy. When data from all 10 subjects were analyzed together, there was no significant change in inflammatory index after 3 months of treatment with adalimumab. However, when the 5 patients with a high baseline inflammatory index (>4) were considered separately, there was a significant improvement (mean decrease of 5.2±2.7; p<0

    Steroid-sparing strategies have been attempted in recent decades to avoid morbidity from long-term steroid intake among kidney transplant recipients. Previous systematic reviews of steroid withdrawal after kidney transplantation have shown a significant increase in acute rejection. There are various protocols to withdraw steroids after kidney transplantation and their possible benefits or harms are subject to systematic review. This is an update of a review first published in 2009. To evaluate the benefits and harms of steroid withdrawal or avoidance for kidney transplant recipients. We searched the Cochrane Kidney and Transplant Specialised Register to 15 February 2016 through contact with the Information Specialist using search terms relevant to this review. All randomised and quasi-randomised controlled trials (RCTs) in which steroids were avoided or withdrawn at any time point after kidney transplantation were included. Assessment of risk of bias and data extraction was performed by two authors independently and disagreement resolved by discussion. Statistical analyses were performed using the random-effects model and dichotomous outcomes were reported as relative risk (RR) and continuous outcomes as mean difference (MD) with 95% confidence intervals. We included 48 studies (224 reports) that involved 7803 randomised participants. Of these, three studies were conducted in children (346 participants). The 2009 review included 30 studies (94 reports, 5949 participants). Risk of bias was assessed as low for sequence generation in 19 studies and allocation concealment in 14 studies. Incomplete outcome data were adequately addressed in 22 studies and 37 were free of selective reporting.The 48 included studies evaluated three different comparisons: steroid avoidance or withdrawal compared with steroid maintenance, and steroid avoidance compared with steroid withdrawal. For the adult studies there was no significant difference in patient mortality either in studies

    The objective of this study was to treat posttraumatic anosmia with oral steroid and evaluate its effect. One-hundred sixteen posttraumatic patients whose olfactory thresholds were -1.0 by the phenyl ethyl alcohol threshold test assembled in our department. They were treated with a course of high-dose steroid, and followed up for at least 3 months. During the latter period of this study, magnetic resonance imaging was performed to measure the volumes of olfactory bulbs and to detect subfrontal lobe damage. Among them, 19 (16.4%) patients' olfactory thresholds improved after steroid treatment, but the other 97 patients' thresholds did not change. The incidences of loss of consciousness and intracranial hemorrhage after head injury, the ratios of admission and craniotomy, the intervals between head injury and steroid treatment, the volumes of olfactory bulbs, and the incidences of subfrontal lobe damage were not significantly different between patients whose thresholds improved and those whose thresholds did not improve. However, patients with olfactory improvement were significantly younger than those who remained unchanged. Our study showed that oral steroid treatment might improve olfactory acuity in some patients with posttraumatic anosmia, but the possibility of spontaneous recovery cannot be ruled out.

    Objective This study was performed to confirm the efficacy of long-interval cytapheresis on steroid-dependent ulcerative colitis (UC). Methods To discontinue steroids in patients with steroid-dependent UC, we previously designed a novel regimen of cytapheresis (CAP), which we termed “long-interval cytapheresis (LI-CAP)”, in which CAP was performed as one session every two or three weeks and continued during the whole period of tapering steroid dosage. In this study, we performed LI-CAP therapy 20 times (11 male and 9 female; mean age 41.8 years) between April 2010 and April 2015 for 14 patients with steroid-dependent UC. We evaluated the effectiveness of LI-CAP by examining the improvement in Lichtiger's clinical activity index (CAI), the rate of clinical remission, and the rate of steroid discontinuation. We further examined the rate of sustained steroid-free clinical remission at 6 and 12 months after LI-CAP in patients who successfully discontinued steroid-use after LI-CAP. The primary endpoint was the rate of discontinuation of steroids after LI-CAP. Results The mean CAI score before LI-CAP (7.550) significantly decreased to 1.65 after LI-CAP (p<0.0001). The rate of clinical remission after LI-CAP was 80%. The rate of steroid discontinuation after LI-CAP was 60.0%. The mean dose of daily prednisolone was significantly decreased after LI-CAP (2.30 mg) compared with that before therapy (17.30 mg) (p=0.0003). The rate of sustained steroid-free clinical remission after LI-CAP was 66.7% at 6 months and 66.7% at 12 months. Conclusion We confirmed that LI-CAP has therapeutic effects on reducing the dosage and discontinuing steroids in patients with steroid-dependent UC. PMID:28924114

    The goal of this manuscript is to assess data suggesting that intravitreal injection of anti-vascular endothelial growth factors (anti-VEGFs) could result in systemic adverse events (AEs). The class-specific systemic AEs should be similar to those encountered in cancer trials. The most frequent AE observed in oncology, hypertension and proteinuria, should thus be the most common expected in ophthalmology, but their severity should be lower because of the much lower doses of anti-VEGFs administered intravitreally. Such AEs have not been frequently reported in ophthalmology trials. In addition, pharmacokinetic and pharmacodynamic data describing systemic diffusion of anti-VEGFs should be interpreted with caution because of significant inconsistencies reported. Thus, safety data reported in ophthalmology trials and pharmacokinetic/pharmacodynamic data provide robust evidence that systemic events after intravitreal injection are very unlikely. Additional studies are needed to explore this issue further, as much remains to be understood about local and systemic side effects of anti-VEGFs. Copyright © 2018 Elsevier Masson SAS.

  14. Steroids and endocrine disruptors--History, recent state of art and open questions.

    This introductory chapter provides an overview of the levels and sites at which endocrine disruptors (EDs) affect steroid actions. In contrast to the special issue of Journal of Steroid Biochemistry and Molecular Biology published three years ago and devoted to EDs as such, this paper focuses on steroids. We tried to point to more recent findings and opened questions. EDs interfere with steroid biosynthesis and metabolism either as inhibitors of relevant enzymes, or at the level of their expression. Particular attention was paid to enzymes metabolizing steroid hormones to biologically active products in target cells, such as aromatase, 5α-reductase and 3β-, 11β- and 17β-hydroxysteroid dehydrogenases. An important target for EDs is also steroid acute regulatory protein (StAR), responsible for steroid precursor trafficking to mitochondria. EDs influence receptor-mediated steroid actions at both genomic and non-genomic levels. The remarkable differences in response to various steroid-receptor ligands led to a more detailed investigation of events following steroid/disruptor binding to the receptors and to the mapping of the signaling cascades and nuclear factors involved. A virtual screening of a large array of EDs with steroid receptors, known as in silico methods (≡computer simulation), is another promising approach for studying quantitative structure activity relationships and docking. New data may be expected on the effect of EDs on steroid hormone binding to selective plasma transport proteins, namely transcortin and sex hormone-binding globulin. Little information is available so far on the effects of EDs on the major hypothalamo-pituitary-adrenal/gonadal axes, of which the kisspeptin/GPR54 system is of particular importance. Kisspeptins act as stimulators for hormone-induced gonadotropin secretion and their expression is regulated by sex steroids via a feed-back mechanism. Kisspeptin is now believed to be one of the key factors triggering puberty in

    Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease. Prolonged complete remission is rare. Most patients with SLE need long-term treatment with glucocorticoid and immunomodulators. However, side effects because of the above medications are common. We evaluated the effect of adding-on Dan-Chi-Liu-Wei combination (DCLWC) on SLE patients with conventional therapy in tapering steroid and preventing disease flare-up. This was a double-blind and randomized controlled trial. Sixty-six SLE patients were recruited into this study and 53 patients who fulfilled the 1997 revised criteria for the classification of SLE with an SLE disease activity index (SLEDAI) score of 2-12 and a steroid (measured with prednisolone) daily dose of less than 20mg/d were enrolled. The patients were randomized into either an experimental or control group. We checked the urine analysis, hemogram, liver function, renal function, C3, C4, erythrocyte sedimentation rate, and anti-dsDNA, evaluated the SLEDAI score, and recorded the steroid dose at 0 months, 3 months, and 6 months, respectively. After 6 months of study, the C4 and blood urea nitrogen level revealed a statistically significant difference in either group. There was a tendency toward a decreased SLEDAI score in the experimental group (p=0.083) but not in the control group (p=0.867). The steroid dose was not statistically significant in either group. Renal function and liver function revealed no statistically significant statistics changes in either group. Adding-on DCLWC to conventional therapy for the treatment of SLE was safe and might have a borderline effect in decreasing disease activity, but it was not possible to taper the dosage of steroid after 6 months of clinical trial. Therefore, a long-term follow-up and a large-scale study are necessary to confirm the effect of DCLWC. Copyright © 2011 Elsevier Taiwan LLC. All rights reserved.

  1. Modification of the plasma clearance and liver uptake of steroid ester-conjugated oligodeoxynucleotides by association with (lactosylated) low-density lipoprotein.

    Low-density lipoprotein (LDL) has been proposed as carrier for the selective delivery of anticancer drugs to tumor cells. We reported earlier the association of several lipidic steroid-conjugated anticancer oligodeoxynucleotides (ODNs) with LDL. In the present study, we determined the stability of these complexes. When the complexes were incubated with a mixture of high-density lipoprotein and albumin, or with rat plasma, the oleoyl steroid-conjugated ODNs appeared to be more stably associated with LDL than the cholesteryl-conjugated ODN. Intravenously injected free lipid-ODNs were very rapidly cleared from the circulation of rats. The area under the curve (AUC) of the lipid-ODNs in plasma was <0.4 microg x min/mL. After complexation with LDL, plasma clearance of the lipid-ODNs was delayed. This was most evident for ODN-5, the ODN conjugated with the oleoyl ester of lithocholic acid (AUC = 6.82 +/- 1.34 microg x min/mL). The AUC of ODN-4, a cholesteryl-conjugated ODN, was 1.49 +/- 0.37 microg x min/mL. In addition, the liver uptake of the LDL-complexed lipid-ODNs was reduced. The lipid-ODNs were also administered as a complex with lactosylated LDL, a modified LDL particle that is selectively taken up by the liver. A high proportion of ODN-5 was transported to the liver along with lactosylated LDL (69.1 +/- 8.1% of the dose at 15 min after injection), whereas much less ODN-4 was transported (36.6 +/- 0.1% of the dose at 15 min after injection). We conclude that the oleoyl ester of lithocholic acid is a more potent lipid anchor than the other steroid lipid anchors. Because of the stable association, the oleoyl ester of lithocholic acid is an interesting candidate for tumor targeting of anticancer ODNs with lipoproteins.

    High-speed motion pictures were taken of individual fuel sprays from a pump injection system. The changes in the spray-tip penetration with changes in the pump speed, injection-valve opening and closing pressures, discharge-orifice area, injection-tube length and diameter, and pump throttle setting were measured. The pump was used with and without a check valve. The results show that the penetration of the spray tip can be controlled by the dimensions of the injection tube, the area of the discharge orifice, and the injection-valve opening and closing pressures.

    Connexin(Cx)43 and microRNA(miR)-206 play an important role in osteogenesis. However, their role in steroid-induced femoral head osteonecrosis (SANFH) is still ambiguous. The present study aimed to establish a rabbit model and investigate osteogenesis in steroid-induced femoral head osteonecrosis occurring via Cx43/miR-206 and the changes of Wnt/β-catenin signal pathway-related proteins. A total of 72 adult New Zealand white rabbits were divided randomly into a model group (Group A) and a control group (Group B) of 36 rabbits each. Group A was injected intravenously with lipopolysaccharide (10μg/kg body weight, once per day). After 48h, three injections of methylprednisolone (MPS; 20mg/kg body weight) were administered intramuscularly at 24-hour intervals. Group B were fed and housed under identical conditions but received saline injections. All animals were sacrificed at two, four, and eight weeks from the first MPS injection. Typical early osteonecrosis symptoms were observed in Group A. The expression of miR-206 in Group A was significantly higher than that of Group B. The mRNA and protein levels of Cx43, β-catenin, runt-related transcription factor 2, and alkaline phosphatase gradually decreased while Dickkopf-1 (Dkk-1) gradually increased in Group A compared with Group B. These findings indicated that Cx43/miR-206 is involved in the pathogenesis of early stage SANFH and may be associate with Wnt/β-catenin signal pathway. Copyright © 2016 Elsevier Inc.

    Many adverse effects have been associated with abuse of anabolic-androgenic steroids (AAS), including disorders of the urogenital tract. The objective of this study is to analyze the morphological modifications in the prostate ventral lobe of pubertal and adult rats chronically treated with AAS, using morphometric methods. We studied 39 male Wistar rats weighing between 400 g and 550 g. The rats were divided into four groups: (a) control rats, with 105 days of age (C105) (n = 7); (b) control rats with 65 days of age (C65) (n = 9), injected only with the vehicle (peanut oil); (c) treated rats, with 105 days of age (T105) (n = 10) and (d) treated rats with 65 days of age (T65) (n = 13). The treated rats were injected with nandrolone decanoate at a dose of 10 mg.Kg-1 body weight. The steroid hormone and the vehicle were administered by intramuscular injection once a week for eight weeks. The rats were killed at 161 days of age (C105 and T105) and 121 days of age (C65 and T65) and the ventral prostate lobe was dissected and processed for histology. The height of the acinar epithelium, the surface densities of the lumen, epithelium and stroma were observed with X400 magnification using an Olympus light microscope coupled to a Sony CCD video camera, and the images transferred to a Sony monitor KX14-CP1. The selected histological areas were then quantified using the M42 test-grid system on the digitized fields. The data were analyzed with the Graphpad software. To compare the quantitative data in both groups (controls and treated) and the outcomes, Student's t-test was used (p < 0.05 was considered significant). The weight (p < 0.001) and volume (p = 0.004) of the prostate ventral lobe showed differences between C65 and T65 groups and between C105 and T105 groups. The epithelium height showed no difference between groups C65 and T65 (p = 0.8509), but the T105 group showed an increase of 32% compared to C105 (p = 0.0089). Concerning the lumen, surface density presented no

    Unfavorable post-partum changes to mental well-being affect more than half of all women, and are a risk to the health of both mother and baby. Their effects place strains on health and social systems. Currently, no generally accepted theory exists of the causes and mechanisms of post-partum mental disorders. Literature search up to 2012, using PubMed and search words: neuroactive steroids, post-partum mental disorders, depression, corticotropin-releasing hormone and estrogens. There are several theories for post-partum depression. One is that autoimmune diseases are involved. Others revolve around genes responsible or that lead to increased disposition to the disorder. It is likely however that the process is associated with the separation of the placenta and the fetal zone of fetal adrenal gland, the main sources of corticotropin-releasing hormone and sexual and neuroactive steroids during pregnancy, and the ability of the receptor system to adapt to these changes. The central nervous system is able to produce neurosteroids, but the drop in levels of peripheral steroids likely leads to a sudden deficit in neuroinhibitory steroids modulating ionotropic receptors in the brain. Post-partum depression is a multifactorial disease with unknown etiology. It is probably associated with sudden changes in the production of hormones influencing the nervous system, and on the other hand the ability of the receptor system to adapt to these changes. When the relative changes in concentrations of hormones, rather than their absolute levels, is likely more important.

  7. Epidural steroids for treating "failed back surgery syndrome": is fluoroscopy really necessary?

    Epidural steroids are commonly administered in the treatment of "failed back surgery syndrome." Because patient response is dependent on accurate steroid placement, fluoroscopic guidance has been advocated. However, because of ever-increasing medical expenditures, the cost-benefit of routine fluoroscopy should be critically evaluated. Therefore, 50 patients were enrolled into this institutional review board-approved, prospective, controlled, single-blinded study. At a predetermined intervertebral level, the epidural space was identified using an air loss of resistance technique. Thereafter, an epidural catheter was inserted 2 cm through the epidural needle. To determine the accuracy of the clinical placement, contrast medium was administered through the epidural catheter; antero-posterior and lateral lumbar spine radiographs were then obtained. The number of attempts required to successfully locate the epidural space, the reliability of the air loss of resistance technique in indicating successful epidural penetration in failed back surgery syndrome, the ability of the clinician to accurately predict the intervertebral space at which the epidural injection was performed, and the spread of contrast medium within the epidural space were recorded. A total of 48 epidurograms were performed. The number of attempts to successfully enter the epidural space was 2 +/- 1. In 44 cases, the radiological studies confirmed the clinical impression that the epidural space had been successfully identified. In three patients, the epidural catheter was in the paravertebral tissue. One myelogram was recorded. In 25 patients, the epidural catheter did not pass through the predetermined intervertebral space. In 35 cases, the contrast medium did not reach the level of pathology. The clinical sign of loss of resistance is a reliable indicator of epidural space penetration in most cases of "failed back surgery syndrome." However, surface anatomy is unreliable and may result in inaccurate

    We report a case of a 19-year-old girl who presented with 5-year history of swelling of upper lip and fissured tongue treated with dapsone then oral steroids without any improvement. Clinical examination found peripheral facial nerve paralysis and Labial mucosa biopsy showed non-necrotizing giganto-epithelioid granuloma. Diagnosis of Melkersson-Rosenthal syndrome was retaind because of association of cheilitis, lingua plicata and facial paralysis. Given the failure of dapsone and oral steroid we suggested an association of betamethasone injection and doxycycline. Gradual and permanent reduction of the upper lip volume was observed. One year follow up objectified no reactivation of cheilitis. PMID:23397029

    Juvenile idiopathic arthritis often affects the temporomandibular joint (TMJ), resulting in facial deformities, and intra-articular injections of anti-inflammatory steroids used in treatment may inhibit bone growth in the developing condyle. The purpose of this pilot study was to evaluate the anti-inflammatory properties of simvastatin (SIM), a bone anabolic drug, compared with the common steroid triamcinolone hexacetonide (TH) in experimental TMJ arthritis of growing rats. Joint inflammation was induced by injecting complete Freund's adjuvant (CFA) into the TMJs of 32 growing (4-week-old) Sprague-Dawley rats while simultaneously receiving 1) ethanol drug carrier, 2) 0.1 mg of SIM, 3) 0.5 mg of SIM, or 4) 0.15 mg of TH. Six rats had no treatment to the TMJ. Animals were euthanized 28 days later, and TMJs were decalcified and stained with hematoxylin-eosin. Histopathologic TMJ results showed that CFA injection along with drug carrier induced increased thickness of the articular layer on the head of the condyle and inflammation of the retrodiscal area (CFA and ethanol). Although both TH and SIM reduced the articular layer thickness, 0.5 mg of SIM was more effective at reducing subsynovial inflammation. Intra-articular simvastatin showed anti-inflammatory properties in this TMJ model, prompting its further study in the growing TMJ, where bone anabolic properties would be important.

  10. Optimised deconjugation of androgenic steroid conjugates in bovine urine.

    PubMed

    Pedersen, Mikael; Frandsen, Henrik L; Andersen, Jens H

    2017-04-01

    After administration of steroids to animals the steroids are partially metabolised in the liver and kidney to phase 2 metabolites, i.e., glucuronic acid or sulphate conjugates. During analysis these conjugated metabolites are normally deconjugated enzymatically with aryl sulphatase and glucuronidase resulting in free steroids in the extract. It is well known that some sulphates are not deconjugated using aryl sulphatase; instead, for example, solvolysis can be used for deconjugation of these aliphatic sulphates. The effectiveness of solvolysis on androgenic steroid sulphates was tested with selected aliphatic steroid sulphates (boldenone sulphate, nortestosteron sulphate and testosterone sulphate), and the method was validated for analysis of androgenic steroids in bovine urine using free steroids, steroid sulphates and steroid glucuronides as standards. Glucuronidase and sulphuric acid in ethyl acetate were used for deconjugation and the extract was purified by solid-phase extraction. The final extract was evaporated to dryness, re-dissolved and analysed by LC-MS/MS.

    The inappropriate programming of developing organ systems by exposure to excess native or environmental steroids, particularly the contamination of our environment and our food sources with synthetic endocrine disrupting chemicals that can interact with steroid receptors, is a major concern. Studies with native steroids have found that in utero exposure of sheep to excess testosterone, an estrogen precursor, results in low birth weight offspring and leads to an array of adult reproductive / metabolic deficits manifested as cycle defects, functional hyperandrogenism, neuroendocrine / ovarian defects, insulin resistance, and hypertension. Furthermore, the severity of reproductive dysfunction is amplified by excess postnatal weight gain. The constellation of adult reproductive and metabolic dysfunction in prenatal testosterone-treated sheep is similar to features seen in women with polycystic ovary syndrome. Prenatal dihydrotestosterone treatment failed to result in similar phenotype suggesting that many effects of prenatal testosterone excess are likely facilitated via aromatization to estradiol. Similarly, exposure to environmental steroid imposters such as bisphenol A (BPA) and methoxychlor (MXC) from days 30-90 of gestation had long-term but differential effects. Exposure of sheep to BPA, which resulted in maternal levels of 30-50 ng/ml BPA, culminated in low birth-weight offspring. These female offspring were hypergonadotropic during early postnatal life and characterized by severely dampened preovulatory LH surges. Prenatal MXC-treated females had normal birth weight and manifested delayed but normal amplitude LH surges. Importantly, the effects of BPA were evident at levels, which approximated twice the highest levels found in human maternal circulation of industrialized nations. These findings provide evidence in support of developmental origin of adult reproductive and metabolic diseases and highlight the risk posed by exposure to environmental endocrine

  12. Steroid Assays in Paediatric Endocrinology

    PubMed Central

    2010-01-01

    Most steroid disorders of the adrenal cortex come to clinical attention in childhood and in order to investigate these problems, there are many challenges to the laboratory which need to be appreciated to a certain extent by clinicians. The analysis of sex steroids in biological fluids from neonates, over adrenarche and puberty present challenges of specificities and concentrations often in small sample sizes. Different reference ranges are also needed for interpretations. For around 40 years, quantitative assays for the steroids and their regulatory peptide hormones have been possible using immunoassay techniques. Problems are recognised and this review aims to summarise the benefits and failings of immunoassays and introduce where tandem mass spectrometry is anticipated to meet the clinical needs for steroid analysis in paediatric endocrine investigations. It is important to keep a dialogue between clinicians and the laboratory, especially when any laboratory result does not make sense in the clinical investigation. Conflict of interest:None declared.

    A dual-channel sequential injection microchip capillary electrophoresis system with pressure-driven injection is demonstrated for simultaneous separations of anions and cations from a single sample. The poly(methyl methacrylate) (PMMA) microchips feature integral in-plane contactless conductivity detection electrodes. A novel, hydrodynamic "split-injection" method utilizes background electrolyte (BGE) sheathing to gate the sample flows, while control over the injection volume is achieved by balancing hydrodynamic resistances using external hydrodynamic resistors. Injection is realized by a unique flow-through interface, allowing for automated, continuous sampling for sequential injection analysis by microchip electrophoresis. The developed system was very robust, with individual microchips used for up to 2000 analyses with lifetimes limited by irreversible blockages of the microchannels. The unique dual-channel geometry was demonstrated by the simultaneous separation of three cations and three anions in individual microchannels in under 40 s with limits of detection (LODs) ranging from 1.5 to 24 μM. From a series of 100 sequential injections the %RSDs were determined for every fifth run, resulting in %RSDs for migration times that ranged from 0.3 to 0.7 (n = 20) and 2.3 to 4.5 for peak area (n = 20). This system offers low LODs and a high degree of reproducibility and robustness while the hydrodynamic injection eliminates electrokinetic bias during injection, making it attractive for a wide range of rapid, sensitive, and quantitative online analytical applications.

    Study Design: A randomized, double-blind, active-controlled trial. Objective: To assess the effectiveness of cervical interlaminar epidural injections of local anesthetic with or without steroids for the management of axial or discogenic pain in patients without disc herniation, radiculitis, or facet joint pain. Summary of Background Data: Cervical discogenic pain without disc herniation is a common cause of suffering and disability in the adult population. Once conservative management has failed and facet joint pain has been excluded, cervical epidural injections may be considered as a management tool. Despite a paucity of evidence, cervical epidural injections are one of the most commonly performed nonsurgical interventions in the management of chronic axial or disc-related neck pain. Methods: One hundred and twenty patients without disc herniation or radiculitis and negative for facet joint pain as determined by means of controlled diagnostic medial branch blocks were randomly assigned to one of the 2 treatment groups. Group I patients received cervical interlaminar epidural injections of local anesthetic (lidocaine 0.5%, 5 mL), whereas Group II patients received 0.5% lidocaine, 4 mL, mixed with 1 mL or 6 mg of nonparticulate betamethasone. The primary outcome measure was ≥ 50% improvement in pain and function. Outcome assessments included numeric rating scale (NRS), Neck Disability Index (NDI), opioid intake, employment, and changes in weight. Results: Significant pain relief and functional improvement (≥ 50%) was present at the end of 2 years in 73% of patients receiving local anesthetic only and 70% receiving local anesthetic with steroids. In the successful group of patients, however, defined as consistent relief with 2 initial injections of at least 3 weeks, significant improvement was illustrated in 78% in the local anesthetic group and 75% in the local anesthetic with steroid group at the end of 2 years. The results reported at the one-year follow

    Importance Rising pharmaceutical costs in the United States are an increasing source of financial burden for payers and patients. Although topical steroids are among the most commonly prescribed medications in dermatology, there are limited data on steroid-related spending and utilization. Objective To characterize Medicare and patient out-of-pocket costs for topical steroids, and to model potential savings that could result from substitution of the cheapest topical steroid from the corresponding potency class. Design, Setting, and Participants This study was a retrospective cost analysis of the Medicare Part D Prescriber Public Use File, which details annual drug utilization and spending on both generic and branded drugs from 2011 to 2015 by Medicare Part D participants who filled prescriptions for topical steroids. Main Outcomes and Measures Total and potential Medicare and out-of-pocket patient spending. Costs were adjusted for inflation and reported in 2015 dollars. Results Medicare Part D expenditures on topical steroids between 2011 and 2015 were $2.3 billion. Patients’ out-of-pocket spending for topical steroids over the same period was $333.7 million. The total annual spending increased from $237.6 million to $775.9 million, an increase of 226.5%. Patients’ annual out-of-pocket spending increased from $41.4 million to $101.8 million, an increase of 145.9%. The total number of prescriptions were 7.7 million in 2011 and 10.6 million in 2015, an increase of 37.0%. Generic medication costs accounted for 97.8% of the total spending during this time period. The potential health care savings and out-of-pocket patient savings from substitution of the cheapest topical steroid within the corresponding potency class were $944.8 million and $66.6 million, respectively. Conclusions and Relevance Most topical steroids prescribed were generic drugs. There has been a sharp increase in Medicare and out-of-pocket spending on topical steroids that is driven by higher

    To evaluate whether adding perioperative topical ketorolac tromethamine 0.4% improves cataract surgery outcomes relative to topical steroids alone in patients without known risk factors for cystoid macular edema (CME). Prospective, randomized, investigator-masked, multicenter clinical trial. Patients scheduled to undergo phacoemulsification and with no recognized CME risks (diabetic retinopathy, retinal vascular disease, or macular abnormality) were randomized to receive either prednisolone acetate 1% 4 times daily (QID) alone (steroid group; n = 278) or prednisolone 1% QID plus ketorolac 0.4% QID (ketorolac/steroid group; n = 268) for approximately four weeks postoperatively. In the ketorolac/steroid group, patients also received topical ketorolac 0.4% QID for three days preoperatively. In both groups, patients received four doses of ketorolac 0.4% one hour before surgery. Patients with capsular disruption or vitreous loss intraoperatively were exited from the study. Outcome measures included CME incidence, retinal thickness as measured by optical coherence tomography (OCT), best-corrected visual acuity, and contrast sensitivity. No patients in the ketorolac/steroid group and five patients in the steroid group had clinically apparent CME (P = .032). Based on OCT, no ketorolac/steroid patient had definite or probable CME, compared with six steroid patients (2.4%; P = .018). In the ketorolac/steroid group, mean retinal thickening was less (3.9 microm vs 9.6 microm; P = .003), and fewer patients had retinal thickening of more than 10 microm as compared with the steroid group (26% vs 51%; P < .001). This study suggests that adding perioperative ketorolac to postoperative prednisolone significantly reduces the incidences of CME and macular thickening in cataract surgery patients already at low risk for this condition.

    Steroid profiling is the most versatile and informative technique adapted by doping control laboratories for detection of steroid abuse. The absolute concentrations and ratios of endogenous steroids including testosterone, epitestosterone, androsterone, etiocholanolone, 5α-androstane-3α,17β-diol and 5β-androstane-3α,17β-diol constitute the significant characteristics of a steroid profile. In the present study we report the influence of various oxidizing adulterants on the steroid profile of human urine. Gas chromatography-mass spectrometry analysis was carried out to develop the steroid profile of human male and female urine. Oxidants potassium nitrite, sodium hypochlorite, potassium permanganate, cerium ammonium nitrate, sodium metaperiodate, pyridinium chlorochromate, potassium dichromate and potassium perchlorate were reacted with urine at various concentrations and conditions and the effect of these oxidants on the steroid profile were analyzed. Most of the oxidizing chemicals led to significant changes in endogenous steroid profile parameters which were considered stable under normal conditions. These oxidizing chemicals can cause serious problems regarding the interpretation of steroid profiles and have the potential to act as masking agents that can complicate or prevent the detection of the steroid abuse.

    Background Chronic low back pain without disc herniation is common. Various modalities of treatments are utilized in managing this condition, including epidural injections. However, there is continued debate on the effectiveness, indications, and medical necessity of any treatment modality utilized for managing axial or discogenic pain, including epidural injections. Methods A randomized, double-blind, actively controlled trial was conducted. The objective was to evaluate the ability to assess the effectiveness of caudal epidural injections of local anesthetic with or without steroids for managing chronic low back pain not caused by disc herniation, radiculitis, facet joints, or sacroiliac joints. A total of 120 patients were randomized to two groups; one group did not receive steroids (group 1) and the other group did (group 2). There were 60 patients in each group. The primary outcome measure was at least 50% improvement in Numeric Rating Scale and Oswestry Disability Index. Secondary outcome measures were employment status and opioid intake. These measures were assessed at 3, 6, 12, 18, and 24 months after treatment. Results Significant pain relief and functional status improvement (primary outcome) defined as a 50% or more reduction in scores from baseline, were observed in 54% of patients in group 1 and 60% of patients in group 2 at 24 months. In contrast, 84% of patients in group 1 and 73% in group 2 saw significant pain relief and functional status improvement in the successful groups at 24 months. Conclusion Caudal epidural injections of local anesthetic with or without steroids are effective in patients with chronic axial low back pain of discogenic origin without facet joint pain, disc herniation, and/or radiculitis.

    Steroids are perhaps one of the most widely used group of drugs in present day. Beside the established utilization as immunosuppressive, anti-inflammatory, anti-rheumatic, progestational, diuretic, sedative, anabolic and contraceptive agents, recent applications of steroid compounds include the treatment of some forms of cancer, osteoporosis, HIV infections and treatment of declared AIDS. Steroids isolated are often available in minute amounts. So biotransformation of natural products provides a powerful means in solving supply problems in clinical trials and marketing of the drug for obtaining natural products in bulk amounts. If the structure is complex, it is often an impossible task to isolate enough of the natural products for clinical trials. The microbial biotransformation of steroids yielded several novel metabolites, exhibiting different activities. The metabolites produced from pregnenolone acetate by Cunning hamella elegans and Rhizopus stolonifer were screened against tyrosinase and cholinesterase showed significant inhibitory activities than the parent compound. Diosgenin and its transformed sarsasapogenin were screened for their acetyl cholinesterase and butyryl cholinesterase inhibitory activities. Sarsasapogenin was screened for phytotoxicity, and was found to be more active than the parent compound. Diosgenin, prednisone and their derivatives were screened for their anti-leishmanial activity. All derivatives were found to be more active than the parent compound. The biotransformation of steroids have been reviewed to a little extent. This review focuses on the biotransformation and functions of selected steroids, the classification, advantages and agents of enzymatic biotransformation and examines the potential role of new enzymatically transformed steroids and their derivatives in the chemoprevention and treatment of other diseases. tyrosinase and cholinesterase inhibitory activities, severe asthma, rheumatic disorders, renal disorders and

    No randomized controlled trial has evaluated the efficacy of steroids in acute cerebral venous thrombosis (CVT). We aimed to analyze the effect of steroids on the outcome of patients in the International Study on Cerebral Veins and Dural Sinus Thrombosis (ISCVT). ISCVT is a prospective observational study that included 624 CVT patients. Death or dependence at 6 months was compared between cases (patients treated with steroids) and controls (patients not treated with steroids), using 3 designs: (1) Matched case-control study (each case matched with a control for prognostic factors); (2) Nonmatched case-control study of the ISCVT cohort; (3) Case-control study in different strata according to the number of poor prognostic variables in each patient. One hundred and fifty (24%) patients were treated with steroids. (1) In the matched case-control study, poor outcome was similar in the two groups of patients (26/146 versus 17/149, OR=1.7; 95% CI 0.9 to 3.3, P=0.119). (2) In the ISCVT cohort, no significant difference in poor outcomes was found whether patients were treated with steroids or not (26/146 versus 60/469, OR=1.5; 95% CI 0.9 to 2.4). Patients without parenchymal lesions treated with steroids had worse prognosis than those treated without steroids (8/45 versus 9/184, OR=4.2, 95% CI 1.6 to 11.6, P=0.008). (3) Treatment with steroids was not associated with a better outcome in any strata of patients according to the number of poor prognostic factors. Steroids in the acute phase of CVT were not useful and were detrimental in patients without parenchymal cerebral lesions. These results do not support the use of steroids in CVT (evidence level III).

    A tracer-encapsulated solid pellet (TESPEL) injection system for the TJ-II stellarator was recently developed. In order to reduce the time and cost for the development, we combined a TESPEL injector provided by National Institute for Fusion Science with an existing TJ-II cryogenic pellet injection system. Consequently, the TESPEL injection into the TJ-II plasma was successfully achieved, which was confirmed by several pellet diagnostics including a normal-incidence spectrometer for monitoring a tracer impurity behavior.

    Sex steroidal hormones coordinate the development and maintenance of tissue architecture in many organs, including the central nervous systems (CNS). Within the CNS, sex steroids regulate the morphology, physiology, and behavior of a wide variety of neural cells including, but not limited to, neurons, glia, endothelial cells, and immune cells. Sex steroids spatially and temporally control distinct molecular networks, that, in turn modulate neural activity, synaptic plasticity, growth factor expression and function, nutrient exchange, cellular proliferation, and apoptosis. Over the last several decades, it has become increasingly evident that sex steroids, often in conjunction with neuroinflammation, have profound impact on the occurrence and severity of neuropsychiatric and neurodegenerative disorders. Here, I review the foundational discoveries that established the regulatory role of sex steroids in the CNS and highlight recent advances toward elucidating the complex interaction between sex steroids, neuroinflammation, and CNS regeneration through adult neurogenesis. The majority of recent work has focused on neuroinflammatory responses following acute physical damage, chronic degeneration, or pharmacological insult. Few studies directly assess the role of immune cells in regulating adult neurogenesis under healthy, homeostatic conditions. As such, I also introduce tractable, non-traditional models for examining the role of neuroimmune cells in natural neuronal turnover, seasonal plasticity of neural circuits, and extreme CNS regeneration.

    Alkaline phosphatase (ALP) has been used as one of the biomarkers for bone resorption and liver diseases. Normally, total alkaline phosphatase is quantified along with other symptoms to determine the releasing source of the alkaline phosphatase. A semi-automated flow injection-bead injection system was proposed to conveniently and selectively assay bone alkaline phosphatase (BALP) based on its specific binding to wheat germ coated beads. Amount of BALP in serum was determined from the intensity of the yellow product produced from bound BALP on the retained beads and its substrate pNPP. The used beads were discarded and the fresh ones were introduced for the next analysis. The reaction cell was designed to be opened and closed using a computer controlled solenoid valve for a precise incubation time. The performance of the proposed system was evaluated by using it to assay BALP in human serum. The results were compared to those obtained by using a commercial ELISA kit. The system is proposed to be an easy and cost effective system for quantification of BALP as an alternative to batch wise wheat germ specific binding technique.

    The detection of misuse with naturally occurring steroids is a great challenge for doping control laboratories. Intake of natural anabolic steroids alters the steroid profile. Thus, screening for exogenous use of these steroids can be established by monitoring a range of endogenous steroids, which constitute the steroid profile, and evaluate their concentrations and ratios against reference ranges. Elevated values of the steroid profile constitute an atypical finding after which a confirmatory IRMS procedure is needed to unequivocally establish the exogenous origin of a natural steroid. However, the large inter-individual differences in urinary steroid concentrations and the recent availability of a whole range of natural steroids (e.g. dehydroepiandrosterone and androstenedione) which each exert a different effect on the monitored parameters in doping control complicate the interpretation of the current steroid profile. The screening of an extended steroid profile can provide additional parameters to support the atypical findings and can give specific information upon the steroids which have been administered. The natural concentrations of 29 endogenous steroids and 11 ratios in a predominantly Caucasian population of athletes were determined. The upper reference values at 97.5%, 99% and 99.9% levels were assessed for male (n=2027) and female (n=1004) populations. Monitoring minor metabolites and evaluation of concentration ratios with respect to their natural abundances could improve the interpretation of the steroid profile in doping analysis.

    Rosen, C J; Glowacki, J; Craig, W

    1998-01-01

    Aging is associated with profound changes in the growth hormone/insulin-like growth factor (IGF) regulatory system. These include reductions in growth hormone, IGF-I, IGFBP3, and IGFBP-5 and an increase in IGFBP-4. These changes, coupled with rather marked declines in sex steroid production from both the ovary and adrenals may combine to have very deleterious effects on several organ systems in the postmenopausal woman. In particular, the prevalence of two very common diseases, osteoporosis and coronary artery disease, increase dramatically after the cessation of gonadal steroid production. The complex interrelationship between the IGF regulatory system and estrogens/androgens in the postmenopausal period may provide important clues as to the pathophysiology of both these disorders. In this paper, we begin to define the role of IGF-I (and its constituent IGF binding proteins) in skeletal and vascular tissue. Recent experimental data show the effects of estrogen on circulating and tissue IGFs in older individuals. Finally, estrogen replacement therapy affects the IGF regulatory system in postmenopausal women. Although conclusions from early studies remain somewhat preliminary, it is likely that the IGF regulatory system will be a prime target for future studies into the pathogenesis of several age and sex hormone related degenerative disorders.

  11. Systemic effects of intranasal steroids: an endocrinologist's perspective.

    Intranasal steroids (INSs) are established as first-line treatment for allergic rhinitis. Extensive use of INSs with few reported adverse events supports the safety of these medications. Nevertheless, the prescription of more potent INSs for consistent and more prolonged use to younger and older patients, often in combination with inhaled corticosteroids, justifies the careful examination of their potential adverse systemic effects. Systemic bioavailability of INSs, by way of nasal and intestinal absorption, can be substantial; but current INSs vary significantly in their degree of first-pass hepatic inactivation and clearance from the body of the swallowed drug. For safety studies of INSs, distinguishing detectable physiologic perturbations from important adverse events is aided by an understanding of normal endocrine physiology and the methods used to test these systems. A review of available information indicates that (1) sensitive tests can measure the effects of INSs on biologic feedback systems, but they do not accurately predict clinically relevant adverse effects; (2) the primary factors that influence the relationship between therapeutic and adverse systemic effects of INSs are dosing frequency and efficiency of hepatic inactivation of swallowed drug; (3) INS treatment in recommended doses does not cause clinically significant hypothalamic-pituitary-adrenal axis suppression; (4) growth suppression can occur with twice-daily administration of certain INSs but does not appear to occur with once-daily dosing or with agents with more complete first-pass hepatic inactivation; (5) harmful effects of INSs on bone metabolism have not yet been adequately studied but would not be expected with the use of an INS dose and dosing frequency that do not suppress basal hypothalamic-pituitary-adrenal axis function or growth; and (6) these conclusions apply to INS treatment alone and in recommended doses-the risk of adverse effects in individual patients who are treated

    We described a microfluidic chip-based system capable of generating droplet array with a large scale concentration gradient by coupling flow injection gradient technique with droplet-based microfluidics. Multiple modules including sample injection, sample dispersion, gradient generation, droplet formation, mixing of sample and reagents, and online reaction within the droplets were integrated into the microchip. In the system, nanoliter-scale sample solution was automatically injected into the chip under valveless flow injection analysis mode. The sample zone was first dispersed in the microchannel to form a concentration gradient along the axial direction of the microchannel and then segmented into a linear array of droplets by immiscible oil phase. With the segmentation and protection of the oil phase, the concentration gradient profile of the sample was preserved in the droplet array with high fidelity. With a single injection of 16 nL of sample solution, an array of droplets with concentration gradient spanning 3-4 orders of magnitude could be generated. The present system was applied in the enzyme inhibition assay of β-galactosidase to preliminarily demonstrate its potential in high throughput drug screening. With a single injection of 16 nL of inhibitor solution, more than 240 in-droplet enzyme inhibition reactions with different inhibitor concentrations could be performed with an analysis time of 2.5 min. Compared with multiwell plate-based screening systems, the inhibitor consumption was reduced 1000-fold. © 2011 American Chemical Society

    Clinical outcomes between the use of platelet-rich plasma (PRP), autologous blood (AB) and corticosteroid (CS) injection in lateral epicondylitis are still controversial. A systematic review and network meta-analysis of randomized controlled trials was conducted with the aim of comparing relevant clinical outcomes between the use of PRP, AB and CS injection. Medline and Scopus databases were searched from inception to January 2015. A network meta-analysis was performed by applying weight regression for continuous outcomes and a mixed-effect Poisson regression for dichotomous outcomes. Ten of 374 identified studies were eligible. When compared to CS, AB injection showed significantly improved effects with unstandardized mean differences (UMD) in pain visual analog scale (VAS), Disabilities of Arm Shoulder and Hand (DASH), Patient-Related Tennis Elbow Evaluation (PRTEE) score and pressure pain threshold (PPT) of -2.5 (95 % confidence interval, -3.5, -1.5), -25.5 (-33.8, -17.2), -5.3 (-9.1, -1.6) and 9.9 (5.6, 14.2), respectively. PRP injections also showed significantly improved VAS and DASH scores when compared with CS. PRP showed significantly better VAS with UMD when compared to AB injection. AB injection has a higher risk of adverse effects, with a relative risk of 1.78 (1.00, 3.17), when compared to CS. The network meta-analysis suggested no statistically significant difference in multiple active treatment comparisons of VAS, DASH and PRTEE when comparing PRP and AB injections. However, AB injection had improved DASH score and PPT when compared with PRP injection. In terms of adverse effects, AB injection had a higher risk than PRP injection. This network meta-analysis provided additional information that PRP injection can improve pain and lower the risk of complications, whereas AB injection can improve pain, disabilities scores and pressure pain threshold but has a higher risk of complications.

    Purpose The purpose of this study was to describe a combination treatment for choroidal neovascular (CNV) membrane, secondary to punctate inner choroidopathy (PIC). Patient and methods A 44-year-old female patient was diagnosed with PIC complicated by the development of recurrent juxtafoveal neovascular membrane. The treatment included a sequence of monotherapy regimens: systemic steroid therapy, photodynamic therapy, and intravitreal injections of vascular endothelial growth factor (VEGF) inhibitor (anti-VEGF). Owing to the CNV membrane resistance to various types of monotherapy, a combination treatment consisting of local injections of steroid underneath the Tenon’s capsule and intravitreal anti-VEGF injections was used. Results Systemic steroid therapy resulted in rapid local improvement with a very short remission period. No positive effects of photodynamic therapy were observed. Sequential anti-VEGF injections led to remission periods of several months. Permanent regression of CNV membrane was achieved following combined local application of steroid and intravitreal anti-VEGF injections. Conclusion A combination treatment including steroid and anti-VEGF medication characterized by anti-inflammatory and antiangiogenic effects may be a very beneficial option for the treatment of recurrent CNV membrane as a complication of PIC.

    Injection for interdigital neuroma (IDN) may not selectively target the common digital nerve. We investigated the anatomical localization and extent of extravasation with injection for IDN. Two fellowship-trained foot and ankle surgeons injected radiopaque contrast into the third webspace of 49 cadaveric specimens (29 with 2 mL and 20 with 1 mL). Computed tomography scan of each specimen was obtained. An independent blinded foot and ankle surgeon analyzed the scans. All injections were accurate. Contrast was found in the second (greater than 70%) and fourth (greater than 30%) webspaces in both injection volume groups. No contrast was found within the third metatarsophalangeal joint. Extravasation extent was significantly greater with 2 mL versus 1 mL of solution in the medial to lateral (27.9 [7.8] mm vs 23.7 [6.0] mm; P = .05) and distal to proximal (52.1 [13.7] mm vs 40.4 [16.1] mm; P = .01) planes. No differences were observed in extravasation extent between surgeons. Injection for IDN was accurate, and extravasation extended into adjacent webspaces in a large percentage of specimens with both solution volumes. Lower extent of extravasation with 1 mL of solution did not indicate better selectivity of injection. Steroid injections for interdigital neuroma were accurate for therapeutic purposes but not diagnostic, except potentially for distinguishing webspace pain from joint pain.

    Gestational exposure to excess T leads to intrauterine growth restriction, low birth weight, and adult metabolic/reproductive disorders in female sheep. We hypothesized that as early mediators of such disruptions, gestational T disrupts steroidal and metabolic homeostasis in both the mother and fetus by both androgenic and metabolic pathways. Maternal blood samples were measured weekly for levels of insulin, glucose, and progesterone from four groups of animals: control; gestational T (twice weekly im injections of 100 mg of T propionate from d 30 to d 90 of gestation); T plus an androgen antagonist, flutamide (15 mg/kg·d oral; T-Flutamide); and T plus the insulin sensitizer, rosiglitazone (0.11 mg/kg·d oral; T-Rosi) (n = 10–12/group). On day 90 of gestation, maternal and umbilical cord samples were collected after a 48-hour fast from a subset (n = 6/group) for the measurement of steroids, free fatty acids, amino acids, and acylcarnitines. Gestational T decreased maternal progesterone levels by 36.5% (P < .05), which was prevented by flutamide showing direct androgenic mediation. Gestational T also augmented maternal insulin levels and decreased medium chained acylcarnitines, suggesting increased mitochondrial fatty acid oxidation. These changes were prevented by rosiglitazone, suggesting alterations in maternal fuel use. Gestational T-induced increases in fetal estradiol were not prevented by either cotreatment. Gestational T disrupted associations of steroids with metabolites and progesterone with acylcarnitines, which was prevented either by androgen antagonist or insulin sensitizer cotreatment. These findings suggest a future combination of these treatments might be required to prevent alteration in maternal/fetal steroidal and metabolic milieu(s). PMID:25763641

    Fulminant hepatic failure is a life-threatening disease. Hepatitis A virus (HAV) can cause fulminant hepatic failure and death in about 0.2% of cases. Extensive destruction of infected hepatocytes by immune-mediated lysis is thought to be the cause. We aimed to evaluate the use of steroid therapy in children with fulminant HAV. This study included 33 children with fulminant HAV in two groups. Steroid group: comprised of 18 children who received prednisolone (1 mg/kg/d) or its equivalent dose of methylprednisolone, and the nonsteroid group: comprised another 15 children who did not receive steroid therapy. Age and sex were matched for both groups (P > .05), and they were comparable regarding baseline clinical and laboratory characteristics. Of the steroid group, 15 patients survived and 3 died, while in the nonsteroid group, 4 patients survived and 11 died (P = .001). Of the living patients, 15 of 19 (78.9%) received steroids while only 3 of 14 (21.4%) of the dead patients received steroids (P = .001). Stepwise regression analysis showed that steroid therapy was the only independent variable associated with recovery (P = .001). Steroid therapy in children with fulminant HAV associated significantly with improved outcome and survival. Future studies on a larger population size are strongly recommended. © 2018 John Wiley & Sons Ltd.

    2015-06-01

    There is increasing recognition that sex hormones (estrogen, progesterone, and testosterone) have biological and pathophysiological actions in peripheral, non-reproductive organs, including the lung. Clinically, sex differences in the incidence, morbidity and mortality of lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, lung cancer and pulmonary hypertension have been noted, although intrinsic sex differences vs. the roles of sex steroids are still not well-understood. Accordingly, it becomes important to ask the following questions: 1) Which sex steroids are involved? 2) How do they affect different components of the lung under normal circumstances? 3) How does sex steroid signaling change in or contribute to lung disease, and in this regard, are sex steroids detrimental or beneficial? As our understanding of sex steroid signaling in the lung improves, it is important to consider whether such information can be used to develop new therapeutic strategies to target lung diseases, perhaps in both sexes or in a sex-specific manner. In this review, we focus on the basics of sex steroid signaling, and the current state of knowledge regarding how they influence structure and function of specific lung components across the life span and in the context of some important lung diseases. We then summarize the potential for sex steroids as useful biomarkers and therapeutic targets in these lung diseases as a basis for future translational research in the area of gender and individualized medicine.

    Inhaled, intranasal, and cutaneous steroids are prescribed by physicians for a plethora of disease processes including asthma and rhinitis. While the high efficacy of this class of medication is well known, the wide range of adverse effects, both local and systemic, is not well elucidated. It is imperative to monitor total steroid burden in its varied forms as well as tracking for possible side effects that may be caused by a high cumulative dose of steroids. This review article highlights the adverse effects of different steroid modalities as well as suggests a monitoring tool to determine steroid totality and side effects.

  7. Elimination of fuel pressure fluctuation and multi-injection fuel mass deviation of high pressure common-rail fuel injection system

    The influence of fuel pressure fluctuation on multi-injection fuel mass deviation has been studied a lot, but the fuel pressure fluctuation at injector inlet is still not eliminated efficiently. In this paper, a new type of hydraulic filter consisting of a damping hole and a chamber is developed for elimination of fuel pressure fluctuation and multi-injection fuel mass deviation. Linear model of the improved high pressure common-rail system(HPCRS) including injector, the pipe connecting common-rail with injector and the hydraulic filter is built. Fuel pressure fluctuation at injector inlet, on which frequency domain analysis is conducted through fast Fourier transformation, is acquired at different target pressure and different damping hole diameter experimentally. The linear model is validated and can predict the natural frequencies of the system. Influence of damping hole diameter on fuel pressure fluctuation is analyzed qualitatively based on the linear model, and it can be inferred that an optimal diameter of the damping hole for elimination of fuel pressure fluctuation exists. Fuel pressure fluctuation and fuel mass deviation under different damping hole diameters are measured experimentally, and it is testified that the amplitude of both fuel pressure fluctuation and fuel mass deviation decreases first and then increases with the increasing of damping hole diameter. The amplitude of main injection fuel mass deviation can be reduced by 73% at most under pilot-main injection mode, and the amplitude of post injection fuel mass deviation can be reduced by 92% at most under main-post injection mode. Fuel mass of a single injection increases with the increasing of the damping hole diameter. The hydraulic filter proposed by this research can be potentially used to eliminate fuel pressure fluctuation at injector inlet and improve the stability of HPCRS fuel injection.

    Anabolic androgenic steroids (AAS) are illicitly administered to enhance athletic performance and body image. Although conferring positive actions on performance, steroid abuse is associated with changes in anxiety and aggression. AAS users are often keenly invested in understanding the biological actions of these drugs. Thus, mechanistic information on AAS actions is important not only for the biomedical community, but also for steroid users. Here we review findings from animal studies on the impact of AAS exposure on neural systems that are crucial for the production of anxiety and aggression, and compare the effects of the different classes of AAS and their potential signaling mechanisms, as well as context-, age- and sex-dependent aspects of their actions.

    In the present study an ultra-performance convergence chromatography tandem mass spectrometry (UPC 2 -MS/MS) analytical method was developed and validated for the determination of 17 C 19 and 14 C 21 steroids, including C11-oxy C 19 and C11-oxy C 21 steroids. The limit of detection and limit of quantification ranged from 0.01 to 10 ng/mL and from 0.01 to 20 ng/mL, respectively, and the method shows the recovery, matrix effect and process efficiency of steroids isolated from a serum matrix to be within acceptable limits. Good accuracy, repeatability and reproducibility were also shown and the method provided excellent sensitivity and selectivity as stereoisomers and regioisomers were also resolved and quantified accurately. Clinical conditions such as congenital adrenal hyperplasia, polycystic ovary syndrome in females and disorders of sex development in neonates and in children, amongst others, are characterized by abnormal steroid levels. Steroid profiling is essential to accurately diagnose steroid levels in the above settings as well as in androgen excess or deficiency in adrenal-linked endocrine diseases. Our method, separating C 19 and C 21 steroids in a single chromatographic step, offers a reduced sample turnover rate in the clinical setting, while providing comprehensive steroid profiles of in vivo steroids in the nmol/L range. This is, to our knowledge, the first method reported to simultaneously separate C 19 and C 21 steroids, together with their C11-hydroxy and C11-keto metabolites -one which may hold promise in the identification of new steroid markers in steroid-linked endocrine diseases, in addition to profiling steroid metabolism and abnormal enzyme activity in patients.

    The use of anabolic androgenic steroids has not been traditionally discussed in mainstream medicine. With the increased diagnosis of hypogonadism a heterogeneous population of men is now being evaluated. In this larger patient population the existence of anabolic steroid induced hypogonadism, whether transient or permanent, should now be considered. We performed an initial retrospective database analysis of all 6,033 patients who sought treatment for hypogonadism from 2005 to 2010. An anonymous survey was subsequently distributed in 2012 to established patients undergoing testosterone replacement therapy. Profound hypogonadism, defined as testosterone 50 ng/dl or less, was identified in 97 men (1.6%) in the large retrospective cohort initially reviewed. The most common etiology was prior anabolic androgenic steroid exposure, which was identified in 42 men (43%). Because of this surprising data, we performed an anonymous followup survey of our current hypogonadal population of 382 men with a mean±SD age of 49.2±13.0 years. This identified 80 patients (20.9%) with a mean age of 40.4±8.4 years who had prior anabolic androgenic steroid exposure. Hypogonadal men younger than 50 years were greater than 10 times more likely to have prior anabolic androgenic steroid exposure than men older than 50 years (OR 10.16, 95% CI 4.90-21.08). Prior anabolic androgenic steroid use significantly correlated negatively with education level (ρ=-0.160, p=0.002) and number of children (ρ=-0.281, p<0.0001). Prior anabolic androgenic steroid use is common in young men who seek treatment for symptomatic hypogonadism and anabolic steroid induced hypogonadism is the most common etiology of profound hypogonadism. These findings suggest that it is necessary to refocus the approach to evaluation and treatment paradigms in young hypogonadal men.

  13. Steroid biotransformations in biphasic systems with Yarrowia lipolytica expressing human liver cytochrome P450 genes

    PubMed Central

    2012-01-01

    Background Yarrowia lipolytica efficiently metabolizes and assimilates hydrophobic compounds such as n-alkanes and fatty acids. Efficient substrate uptake is enabled by naturally secreted emulsifiers and a modified cell surface hydrophobicity and protrusions formed by this yeast. We were examining the potential of recombinant Y. lipolytica as a biocatalyst for the oxidation of hardly soluble hydrophobic steroids. Furthermore, two-liquid biphasic culture systems were evaluated to increase substrate availability. While cells, together with water soluble nutrients, are maintained in the aqueous phase, substrates and most of the products are contained in a second water-immiscible organic solvent phase. Results For the first time we have co-expressed the human cytochromes P450 2D6 and 3A4 genes in Y. lipolytica together with human cytochrome P450 reductase (hCPR) or Y. lipolytica cytochrome P450 reductase (YlCPR). These whole-cell biocatalysts were used for the conversion of poorly soluble steroids in biphasic systems. Employing a biphasic system with the organic solvent and Y. lipolytica carbon source ethyl oleate for the whole-cell bioconversion of progesterone, the initial specific hydroxylation rate in a 1.5 L stirred tank bioreactor was further increased 2-fold. Furthermore, the product formation was significantly prolonged as compared to the aqueous system. Co-expression of the human CPR gene led to a 4-10-fold higher specific activity, compared to the co-overexpression of the native Y. lipolytica CPR gene. Multicopy transformants showed a 50-70-fold increase of activity as compared to single copy strains. Conclusions Alkane-assimilating yeast Y. lipolytica, coupled with the described expression strategies, demonstrated its high potential for biotransformations of hydrophobic substrates in two-liquid biphasic systems. Especially organic solvents which can be efficiently taken up and/or metabolized by the cell might enable more efficient bioconversion as compared

    In the steroid-sensitive nephrotic syndrome (SSNS) the prolonged treatment with steroids could decrease the frequency of relapses. We conducted a comparative study of prolonged steroid scheme and the usual treatment of primary SSNS to assess: the number of patients with relapses, mean time to treatment initiation, to remission and to first relapse, total number of relapses, total cumulative dose of steroids, and the steroid toxicity. Patients were divided into two groups: group A (27 patients) received 16-β-methylprednisolone for 12 weeks, reducing the steroid until week 24. Group B (29 patients) received 16-β-methylprednisolone for 12 weeks and placebo until week 24. Cumulative incidence rate of relapse (person/years) for group A was of 36/100 and 66/100 for group B (p=0.04). Average elapsed time to first relapse was of 114 days for group A and of 75 days to for group B (p=0.01). The difference in time for initial response to treatment and up to achieve remission between both groups was not significant. Total cumulative relapses were 9 for group A and 17 for group B (p=0.04). Total patients with relapses were 3 for group A and 7 for group B (p=0.17). Cumulative average dose per patient was 5,243mg/m 2 for group A and 4,306mg/m 2 for group B (p=0.3), and serum cortisol was 14μg/dl for group A and 16μg/dl for group B (p=0.4). There were no steroid toxicity differences between groups. The duration of the treatment had an impact on the number of relapses without increasing steroid toxicity.

    Background/aim: This study aimed to compare the effectiveness of ultrasound (US)-guided injection versus blind injection of corticosteroids in the treatment of carpal tunnel syndrome (CTS). Materials and methods: This prospective, randomized clinical trial included patients with severe CTS based on clinical and electrophysiological criteria. The patients were evaluated for clinical and electrophysiological parameters at baseline and 4 weeks after treatment. Symptom severity and hand function were assessed by the Boston questionnaire. The patients underwent blind injection or US-guided injection. Results: When compared with baseline, both groups showed significant improvement in Boston questionnaire scores and all electrophysiological parameters. Significant differences were observed between the groups for clinical parameters (Boston Symptom Severity Scale: P = 0.007; Functional Status Scale: P < 0.001) in favor of the US-guided group. Conclusion: This study demonstrated that both US-guided and blind injections were effective in reducing symptoms and improving hand function. US-guided injections may yield more effective clinical results in the short-term than blind injections in the treatment of patients with severe CTS.

    Proper storage conditions of biological samples are fundamental to avoid microbiological contamination that can cause chemical modifications of the target analytes. A simple liquid chromatography/tandem mass spectrometry (LC/MS/MS) method through direct injection of diluted samples, without prior extraction, was used to evaluate the stability of phase II metabolites of boldenone and testosterone (glucuronides and sulphates) in intentionally poorly stored equine urine samples. We also considered the stability of some deuterated conjugated steroids generally used as internal standards, such as deuterated testosterone and epitestosterone glucuronides, and deuterated boldenone and testosterone sulphates. The urines were kept for 1 day at room temperature, to mimic poor storage conditions, then spiked with the above steroids and kept at different temperatures (-18 degrees C, 4 degrees C, room temperature). It has been possible to confirm the instability of glucuronide compounds when added to poorly stored equine urine samples. In particular, both 17beta- and 17alpha-glucuronide steroids were exposed to hydrolysis leading to non-conjugated steroids. Only 17beta-hydroxy steroids were exposed to oxidation to their keto derivatives whereas the 17alpha-hydroxy steroids were highly stable. The sulphate compounds were completely stable. The deuterated compounds underwent the same behaviour as the unlabelled compounds. The transformations were observed in urine samples kept at room temperature and at a temperature of 4 degrees C (at a slower rate). No modifications were observed in frozen urine samples. In the light of the latter results, the immediate freezing at -18 degrees C of the collected samples and their instant analysis after thawing is the proposed procedure for preventing the transformations that occur in urine, usually due to microbiological contamination.

    To induce experimental peripheral facial paralysis by inoculation of HSV1 and to compare the effects of steroid, acyclovir, lipoprostoglandin E2 and steroid + acyclovir treatments in terms of clinical recovery, electrophysiologically and histopathologically. A total of 132 adult female rats were used in this study. HSV type 1 strain was inoculated at the back of the left ear by using 27 gauge needle. Of all animals, 70 (53%) rats which developed facial paralysis were divided into five groups (n = 14 for each group) as control, steroid + acyclovir, lipoprostaglandin E1, steroid only and acyclovir only. At the end of the 21 days period, the rats were clinically examined and electrophysiological tests were performed, then decapitated and the nerve specimens were obtained. A modified electroneurography (ENoG) test was performed and the latencies and the amplitudes were compared. The findings of the intact side were better, but with no significant difference. Histopathologicaly edema was significantly smaller in all groups compared to the controls (p < 0.05). Similarly, no difference was seen in terms of vacuolar degeneration and Schwann cell hyperchromatisation among the groups and no significant difference in recovery period and rate of facial paralysis when all groups were compared. Facial paralysis induced by HSV1 recovered spontaneously within a week. In the treatment of facial paralysis, steroid alone, acyclovir alone, steroid + acyclovir, or lipoprostaglandin E1 all reduced edema in the infected facial nerve but there was no statistical difference in of the rate or degree of recovery.

    2016-07-01

    In this paper modeling and common-rail pressure control of high pressure common rail injection system (HPCRIS) is presented. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The mathematical model is validated by the software Matlab and a virtual detailed simulation environment. For the considered HPCRIS, an effective model free controller which is called Extended State Observer - based intelligent Proportional Integral (ESO-based iPI) controller is designed. And this proposed method is composed mainly of the referred ESO observer, and a time delay estimation based iPI controller. Finally, to demonstrate the performances of the proposed controller, the proposed ESO-based iPI controller is compared with a conventional PID controller and ADRC. Copyright © 2016 ISA.

    Doping with endogenous anabolic steroids is one of the most serious issues in sports today. The measurement of anabolic steroid levels in human hair is necessary in order to distinguish between pharmaceutical steroids and natural steroids. This is the first investigation into the physiological concentrations of anabolic steroids in human hair in Chinese subjects. A gas chromatography-tandem mass spectrometry (GC/MS/MS) method was developed for the simultaneous identification and quantitation of five endogenous anabolic steroids (testosterone, epitestosterone, androsterone, etiocholanolone and dehydroepiandrosterone) in hair. After basic hydrolysis, hair samples were extracted with diethyl ether, derivatized and then detected using GC/MS/MS in the multiple-reaction monitoring mode (MRM). The one precursor/two product ion transitions for each anabolic steroid were monitored. The limits of detection for the five endogenous anabolic steroids were in the 0.1-0.2 pg/mg range. All analytes showed good linearity and the extraction recoveries were 74.6-104.5%. Within-day and between-day precisions were less than 20%. This method was applied to the analysis of testosterone, epitestosterone, androsterone, etiocholanolone, and dehydroepiandrosterone in human hair. Full-length hair samples were taken at the skin surface from the vertex of 39 males, 30 females and 11 children from China. None of the subjects were professional athletes. Testosterone and dehydroepiandrosterone were detected in all the hair segments. The physiological concentrations of testosterone were in the range 0.8-24.2 pg/mg, 0.1-16.8 pg/mg and 0.2-11.5 pg/mg in males, females and children, respectively, however, the mean values of dehydroepiandrosterone were much higher than the concentrations of testosterone. These data are suitable reference values and are the basis for the interpretation of results from investigations into the abuse of endogenous anabolic steroids.

    1933-01-01

    Using the method of weighing fuel collected in a receiver during a definite interval of the injection period, rates of discharge were determined, and the effects noted, when various changes were made in a fuel-injection system. The injection system consisted primarily of a by-pass controlled fuel pump and an automatic injection valve. The variables of the system studied were the pump speed, pump-throttle setting, discharge-orifice diameter, injection-valve opening and closing pressures, and injection-tube length and diameter.

  10. Circulating steroids negatively correlate with tinnitus.

    While not a disease entity in itself; symptoms of tinnitus (from Latin tinnio - clink) accompany a number of diseases. Tinnitus prevalence increases with age, deteriorates one's quality of life, and may even result in suicidal behavior. Tinnitus develops in response to a variety of risk factors, otoxic substances, noise exposure, hearing disorders, and psychological alterations. Tinnitus is closely related to mood, depression, and psychological state. In the present study, we focused on alterations of the steroid metabolome and particularly neuroactive, neuroprotective, and immunomodulatory steroids in patients with tinnitus. The study group consisted of 28 patients without evidence of an organic cause of tinnitus as well as without associated diseases or the effect of ototoxic medications. All patients underwent a complete audiological assessment and laboratory tests including routine biochemical markers and quantification of circulating steroids using gas chromatography/mass spectrometry and immunoassays. To rule out a pathology in the cerebellopontine angle area, CT scan or MRI were performed. To diagnose stem lesions, evoked potentials were also measured. Pearson's correlations and multivariate regression were used to assess any links between tinnitus intensity and frequency on the one hand, and steroid levels on the other. Results indicated a significant and consistent negative correlation between tinnitus indices and intensity of adrenal steroidogenesis. The circulating steroid metabolome including hormones and neuroactive, neuroprotective, and immunomodulatory steroids negatively correlates with the degree of tinnitus due to hypothalamo-pituitary-adrenal axis malfunction. Our results may help explain the pathophysiology of tinnitus and improve its diagnosis. However, further studies are needed to verify our postulation. Copyright © 2017 Elsevier Inc.

    2017-06-16

    The chiral pool amino acids have been utilized for the construction of steroidal and non-steroidal architectures in the quest for steroidomimetics. Chirality derived from amino acid-based architectures provides new and easy to incorporate chiral chemical space, which is otherwise very difficult to introduce and comprised of several synthetic steps for asymmetric steroids. The different and exciting ligand-receptor interactions may arise from the use of each amino acid enantiomer that was introduced into the chiral steroidal backbone. The A and D rings of steroidal architectures can be mimicked by the phenyl group of the amino acid tyrosine. The Mitsunobu reaction, nucleophilic substitution and elimination, etc. were utilized for constructing diverse tri- and tetracyclic steroidal skeletons as well as benzofused seco-steroids from amino acids. These benzofused, amino acid-derived steroidal and nonsteroidal molecules had promising biological activity in hormonal related disorders. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  13. Effect of sexual steroids on boar kinematic sperm subpopulations.

    Ayala, E M E; Aragón, M A

    2017-11-01

    Here, we show the effects of sexual steroids, progesterone, testosterone, or estradiol on motility parameters of boar sperm. Sixteen commercial seminal doses, four each of four adult boars, were analyzed using computer assisted sperm analysis (CASA). Mean values of motility parameters were analyzed by bivariate and multivariate statistics. Principal component analysis (PCA), followed by hierarchical clustering, was applied on data of motility parameters, provided automatically as intervals by the CASA system. Effects of sexual steroids were described in the kinematic subpopulations identified from multivariate statistics. Mean values of motility parameters were not significantly changed after addition of sexual steroids. Multivariate graphics showed that sperm subpopulations were not sensitive to the addition of either testosterone or estradiol, but sperm subpopulations responsive to progesterone were found. Distribution of motility parameters were wide in controls but sharpened at distinct concentrations of progesterone. We conclude that kinematic sperm subpopulations responsive to progesterone are present in boar semen, and these subpopulations are masked in evaluations of mean values of motility parameters. © 2017 International Society for Advancement of Cytometry. © 2017 International Society for Advancement of Cytometry.

    Steroid-resistant nephrotic syndrome overwhelmingly progresses to ESRD. More than 30 monogenic genes have been identified to cause steroid-resistant nephrotic syndrome. We previously detected causative mutations using targeted panel sequencing in 30% of patients with steroid-resistant nephrotic syndrome. Panel sequencing has a number of limitations when compared with whole exome sequencing. We employed whole exome sequencing to detect monogenic causes of steroid-resistant nephrotic syndrome in an international cohort of 300 families. Three hundred thirty-five individuals with steroid-resistant nephrotic syndrome from 300 families were recruited from April of 1998 to June of 2016. Age of onset was restricted to <25 years of age. Exome data were evaluated for 33 known monogenic steroid-resistant nephrotic syndrome genes. In 74 of 300 families (25%), we identified a causative mutation in one of 20 genes known to cause steroid-resistant nephrotic syndrome. In 11 families (3.7%), we detected a mutation in a gene that causes a phenocopy of steroid-resistant nephrotic syndrome. This is consistent with our previously published identification of mutations using a panel approach. We detected a causative mutation in a known steroid-resistant nephrotic syndrome gene in 38% of consanguineous families and in 13% of nonconsanguineous families, and 48% of children with congenital nephrotic syndrome. A total of 68 different mutations were detected in 20 of 33 steroid-resistant nephrotic syndrome genes. Fifteen of these mutations were novel. NPHS1 , PLCE1 , NPHS2 , and SMARCAL1 were the most common genes in which we detected a mutation. In another 28% of families, we detected mutations in one or more candidate genes for steroid-resistant nephrotic syndrome. Whole exome sequencing is a sensitive approach toward diagnosis of monogenic causes of steroid-resistant nephrotic syndrome. A molecular genetic diagnosis of steroid-resistant nephrotic syndrome may have important consequences

    ABSTRACT Steroids are ubiquitous in natural environments and are a significant growth substrate for microorganisms. Microbial steroid metabolism is also important for some pathogens and for biotechnical applications. This study delineated the distribution of aerobic steroid catabolism pathways among over 8,000 microorganisms whose genomes are available in the NCBI RefSeq database. Combined analysis of bacterial, archaeal, and fungal genomes with both hidden Markov models and reciprocal BLAST identified 265 putative steroid degraders within only Actinobacteria and Proteobacteria, which mainly originated from soil, eukaryotic host, and aquatic environments. These bacteria include members of 17 genera not previously known to contain steroid degraders. A pathway for cholesterol degradation was conserved in many actinobacterial genera, particularly in members of the Corynebacterineae, and a pathway for cholate degradation was conserved in members of the genus Rhodococcus. A pathway for testosterone and, sometimes, cholate degradation had a patchy distribution among Proteobacteria. The steroid degradation genes tended to occur within large gene clusters. Growth experiments confirmed bioinformatic predictions of steroid metabolism capacity in nine bacterial strains. The results indicate there was a single ancestral 9,10-seco-steroid degradation pathway. Gene duplication, likely in a progenitor of Rhodococcus, later gave rise to a cholate degradation pathway. Proteobacteria and additional Actinobacteria subsequently obtained a cholate degradation pathway via horizontal gene transfer, in some cases facilitated by plasmids. Catabolism of steroids appears to be an important component of the ecological niches of broad groups of Actinobacteria and individual species of Proteobacteria. PMID:26956583

    The purpose of this study was to evaluate the effect that two steam autoclaves and an unsaturated chemical vapor sterilizer had on killing bacterial endospores present on commercial spore strips or applied to sterile anesthetic injection systems placed within sharps containers. Three types of sterilizers were used: a gravity steam autoclave, a high vacuum steam autoclave and an unsaturated chemical vapor sterilizer. The microbial challenge for the sterilizers were Bacillus stearothermophilus spores present on commercial spore strips or drawn into and applied onto sliding sheath anesthetic injection systems with anesthetic carpules attached. Spore-soiled items were placed into the middle of sharps containers three-quarters-filled with representative clinical waste and sterilized. If, after culturing, sterilization of all test items in a group was not achieved, additional sterilization time was applied. Spore strips were killed within a single cycle of each sterilizer. Spore-soiled injection systems and carpules could not be routinely sterilized in the gravity steam autoclave or unsaturated chemical vapor sterilizers, even after three consecutive sterilization cycles. These items, however, were sterilized by exposure to a single-treatment cycle in a high-vacuum steam autoclave. Results indicate that routine sterilization of spore contaminated anesthetic carpules or injection systems could not be accomplished in a reasonable amount of time using sterilizers commonly found in dental offices.

  18. Transsynaptic trophic effects of steroid hormones in an avian model of adult brain plasticity

    PubMed Central

    Brenowitz, Eliot A.

    2014-01-01

    The avian song control system provides an excellent model for studying transsynaptic trophic effects of steroid sex hormones. Seasonal changes in systemic testosterone (T) and its metabolites regulate plasticity of this system. Steroids interact with the neurotrophin brain-derived neurotrophic factor (BDNF) to influence cellular processes of plasticity in nucleus HVC of adult birds, including the addition of newborn neurons. This interaction may also occur transsynpatically; T increases the synthesis of BDNF in HVC, and BDNF protein is then released by HVC neurons on to postsynaptic cells in nucleus RA where it has trophic effects on activity and morphology. Androgen action on RA neurons increases their activity and this has a retrograde trophic effect on the addition of new neurons to HVC. The functional linkage of sex steroids to BDNF may be of adaptive value in regulating the trophic effects of the neurotrophin and coordinating circuit function in reproductively relevant contexts.

    Background Steroid-responsive encephalopathy associated with subacute thyroiditis has, to our knowledge, not been reported previously. Case Report A 49-year-old woman was found collapsed and brought to our institution with decreased mentality, dysarthria, and gait disturbance. Brain magnetic resonance imaging and angiography were normal but blood tests revealed thyroid-autoantibody-negative thyrotoxicosis. Results of a 99mtechnetium-pertechnetate scan were compatible with the thyrotoxic phase of subacute thyroiditis. 14-3-3 proteins were detected in cerebrospinal fluid. Her mental status began to improve from the day following steroid administration. Recurrent encephalopathy was found 2 months after the initial admission, which was also effectively treated with steroid. Conclusions We speculate that steroid-responsive recurrent encephalopathy associated with subacute thyroiditis is a subtype of Hashimoto's encephalopathy, and consider that steroid treatment should not be delayed in suspected patients.

    To assess the efficacy of the intraarticular steroid(IAS) injection in the management of arthritis and the possible related complications in children with chronic arthritis. We evaluated 11 children of chronic arthritis (4 girls and 7 boys), age of onset ranged from 2-13.6 years, who had persistent arthritis treated with IAS from November 1994 to June 1997. The results of injections showed that the beneficial effect was noted within one day to 2 weeks without significant adverse reactions, remission exceeding 6 months was seen in 10 of 11 patients (in 14 of 18 joints). According to subgroups of chronic arthritis, the remission rate of IAS injection in children with pauciarticular arthritis reached 100%. A significant fall in C-reactive protein (CRP) between pre- and post-IAS injection (p = 0.03), but there were no differences in hemoglobin (Hb), white blood cells (WBCs), thrombocytes (Plts), erythrocyte sedimentation rate (ESR) and osteocalcin level. No injection-related complications were found. In conclusion, the IAS injection was an effective and safe treatment in children with chronic arthritis with no obvious complications especially in pauciarticular arthritis.

    Steroids have been frequently detected in surface waters, and might pose adverse effects on aquatic organisms. However, little information is available regarding the occurrence and spatiotemporal distribution of steroids in lake environments. In addition to pollution sources, the occurrence and spatiotemporal distribution of steroids in lake environments might be related to lake types (shallow or deep), lake hydrodynamics, and sorption-desorption processes in the water-sediment systems. In this study, the occurrence, spatiotemporal distribution, and ecological risks of 36 steroids in a large shallow lake were evaluated by investigating surface water and sediment samples at 32 sites in Lake Taihu over two seasons. Twelve and 15 analytes were detected in aqueous and sedimentary phases, respectively, with total concentrations ranging from 0.86 to 116ng/L (water) and from 0.82 to 16.2ng/g (sediment, dry weight). Temporal variations of steroid concentrations in the water and sediments were statistically significant, with higher concentrations in winter. High concentrations of steroids were found in the seriously polluted bays rather than in the pelagic zone of the lake. Strong lake currents might mix pelagic waters, resulting in similar concentrations of steroids in the pelagic zone. Mass balance analysis showed that sediments in shallow lakes are in general an important sink for steroids. Steroids in the surface water and sediments of Lake Taihu might pose potential risks to aquatic organisms. Overall, our study indicated that the concentrations and spatiotemporal distribution of steroids in the large shallow lake are influenced simultaneously by pollution sources and lake hydrodynamics. Steroids in the large shallow Lake Taihu showed clear temporal and spatial variations and lake sediments may be a potential sink of steroids. Copyright © 2016 Elsevier B.V. All rights reserved.

    Peripheral intracrine sex steroid synthesis from adrenal precursors dehydroepiandrosterone (DHEA) and DHEA-sulfate has evolved in humans. We sought to establish if there are differences in intracrine, paracrine, and endocrine regulation of sex steroids by primary cultures of human skin epidermal keratinocytes and dermal fibroblasts. Microarray analysis identified multifunctional genes modulated by steroids, quantitative RT-PCR (qRT-PCR) mRNA expression, enzymatic assay aromatase activity, scratch assay cell migration, immunocytochemistry α-smooth muscle actin (α-SMA), and collagen gel fibroblast contraction. All steroidogenic components were present, although only keratinocytes expressed the organic anion organic anion transporter protein (OATP) 2B1 transporter. Both expressed the G-protein-coupled estrogen receptor (GPER1). Steroids modulated multifunctional genes, up-regulating genes important in repair and aging [angiopoietin-like 4 (ANGPTL4), chemokine (C-X-C motif) ligand 1 (CXCL1), lamin B1 (LMNB1), and thioredoxin interacting protein (TXNIP)]. DHEA-sulfate (DHEA-S), DHEA, and 17β-estradiol stimulated keratinocyte and fibroblast migration at early (4 h) and late (24-48 h) time points, suggesting involvement of genomic and nongenomic signaling. Migration was blocked by aromatase and steroid sulfatase (STS) inhibitors confirming intracrine synthesis to estrogen. Testosterone had little effect, implying it is not an intermediate. Steroids stimulated fibroblast contraction but not α-SMA expression. Mechanical wounding reduced fibroblast aromatase activity but increased keratinocyte activity, amplifying the bioavailability of intracellular estrogen. Cultured fibroblasts and keratinocytes provide a biologically relevant model system to investigate the complex pathways of sex steroid intracrinology in human skin. © FASEB.

    Background In preclinical testing, ventricular wall injection of hydrogels has been shown to be effective in modulating ventricular remodeling and preserving cardiac function. For some approaches, early-stage clinical trials are under way. The hydrogel delivery method varies, with minimally invasive approaches being preferred. Endocardial injections carry a risk of hydrogel regurgitation into the circulation, and precise injection patterning is a challenge. An epicardial approach with a thermally gelling hydrogel through the subxiphoid pathway overcomes these disadvantages. Methods A relatively stiff, thermally responsive, injectable hydrogel based on N-isopropylacrylamide and N-vinylpyrrolidone (VP gel) was synthesized and characterized. VP gel thermal behavior was tuned to couple with a transepicardial injection robot, incorporating a cooling feature to achieve injectability. Ventricular wall injections of the optimized VP gel have been performed ex vivo and on beating porcine hearts. Results Thermal transition temperature, viscosity, and gelling time for the VP gel were manipulated by altering N-vinylpyrrolidone content. The target parameters for cooling in the robotic system were chosen by thermal modeling to support smooth, repeated injections on an ex vivo heart. Injections at predefined locations and depth were confirmed in an infarcted porcine model. Conclusions A coupled thermoresponsive hydrogel and robotic injection system incorporating a temperature-controlled injectate line was capable of targeted injections and amenable to use with a subxiphoid transepicardial approach for hydrogel injection after myocardial infarction. The confirmation of precise location and depth injections would facilitate a patient-specific planning strategy to optimize injection patterning to maximize the mechanical benefits of hydrogel placement.

    Current challenges in the development of scaffolds for bone regeneration include the engineering of materials that can withstand normal dynamic physiological mechanical stresses exerted on the bone and provide a matrix capable of supporting cell migration and tissue ingrowth. The objective of the present work was to develop and characterize a hybrid polymer–ceramic injectable system that consists of an alginate matrix crosslinked in situ in the presence of strontium(Sr), incorporating a ceramic reinforcement in the form of Sr-rich microspheres. The incorporation of Sr in the microspheres and in the vehicle relies on the growing evidence that Sr has beneficial effects in bone remodeling and in the treatment of osteopenic disorders and osteoporosis. Sr-rich porous hydroxyapatite microspheres with a uniform size and a mean diameter of 555 μm were prepared, and their compression strength and friability tested. A 3.5% (w/v) ultrapure sodium alginate solution was used as the vehicle and its in situ gelation was promoted by the addition of calcium (Ca) or Sr carbonate and Glucone-δ-lactone. Gelation times varied with temperature and crosslinking agent, being slower for Sr than for Ca, but adequate for injection in both cases. Injectability was evaluated using a device employed in vertebroplasty surgical procedures, coupled to a texture analyzer in compression mode. Compositions with 35%w of microspheres presented the best compromise between injectability and compression strength of the system, the force required to extrude it being lower than 100 N.Micro CT analysis revealed a homogeneous distribution of the microspheres inside the vehicle, and a mean inter-microspheres space of 220 μm. DMA results showed that elastic behavior of the hybrid is over the viscous one and that the higher storage modulus was obtained for the 3.5%Alg–35%Sr-HAp-Sr formulation.

  8. Do mollusks use vertebrate sex steroids as reproductive hormones? Part I: Critical appraisal of the evidence for the presence, biosynthesis and uptake of steroids.

    The consensus view is that vertebrate-type steroids are present in mollusks and perform hormonal roles which are similar to those that they play in vertebrates. Although vertebrate steroids can be measured in molluscan tissues, a key question is 'Are they formed endogenously or they are picked up from their environment?'. The present review concludes that there is no convincing evidence for biosynthesis of vertebrate steroids by mollusks. Furthermore, the 'mollusk' genome does not contain the genes for key enzymes that are necessary to transform cholesterol in progressive steps into vertebrate-type steroids; nor does the mollusk genome contain genes for functioning classical nuclear steroid receptors. On the other hand, there is very strong evidence that mollusks are able to absorb vertebrate steroids from the environment; and are able to store some of them (by conjugating them to fatty acids) for weeks to months. It is notable that the three steroids that have been proposed as functional hormones in mollusks (i.e. progesterone, testosterone and 17β-estradiol) are the same as those of humans. Since humans (and indeed all vertebrates) continuously excrete steroids not just via urine and feces, but via their body surface (and, in fish, via the gills), it is impossible to rule out contamination as the sole reason for the presence of vertebrate steroids in mollusks (even in animals kept under supposedly 'clean laboratory conditions'). Essentially, the presence of vertebrate steroids in mollusks cannot be taken as reliable evidence of either endogenous biosynthesis or of an endocrine role. Crown Copyright © 2012.

    To assess the validity of fluoroscopically guided diagnostic intra-articular injections of local anesthetic and effectiveness of intra-articular steroid injections in treating sacroiliac joint (SIJ) pain. Systematic review. Ten reviewers independently assessed 45 publications on diagnostic validity or effectiveness of fluoroscopically guided intra-articular SIJ injections. For diagnostic injections, the primary outcome was validity; for therapeutic injections, analgesia. Secondary outcomes were also described. Of 45 articles reviewed, 39 yielded diagnostic data on physical exam findings, provocation tests, and SIJ injections for diagnosing SIJ pain, and 15 addressed therapeutic effectiveness. When confirmed by comparative local anesthetic blocks with a high degree of pain relief, no single physical exam maneuver predicts response to diagnostic injections. When at least three physical exam findings are present, sensitivity, and specificity increases significantly. The prevalence of SIJ pain is likely 20-30% among patients that have suspected SIJ pain based on history and physical examination. This estimate may be higher in certain subgroups such as the elderly and fusion patients. Two randomized controlled trials and multiple observational studies supported the effectiveness of therapeutic sacroiliac joint injections. Based on this literature, it is unclear whether image-guided intra-articular diagnostic injections of local anesthetic predict positive responses to therapeutic agents. The overall quality of evidence is moderate for the effectiveness of therapeutic SIJ injections. Wiley Periodicals, Inc.

    The pathophysiology of lumbar radicular pain is a subject of ongoing research. The prevalence of sciatica or radiculitis ranges from 1.2% to 43%. Epidural injections are one of the most commonly performed interventions in the United States in managing chronic low back and lower extremity pain secondary to disc herniation and radiculitis. There is a paucity of evidence with contemporary methodology used in performing epidural injections under fluoroscopy and based on pain relief and functional status improvement. A randomized, double-blind, equivalence trial. An interventional pain management practice, a specialty referral center, a private practice setting in the United States. To evaluate the effectiveness of caudal epidural injections with or without steroids in managing chronic low back and lower extremity pain secondary to disc herniation or radiculitis in providing effective and long-lasting pain relief and evaluate the differences between local anesthetic with or without steroids. Patients were assigned to one of 2 groups; Group I patients received caudal epidural injections with an injection of local anesthetic (lidocaine 0.5%), whereas, Group II patients received caudal epidural injections with 0.5% lidocaine 9 mL mixed with 1 mL of steroid. Randomization was performed by computer-generated random allocations sequence by simple randomization. Multiple outcome measures were utilized which included the Numeric Rating Scale (NRS), the Oswestry Disability Index 2.0 (ODI), employment status, and opioid intake with assessment at 3 months, 6 months, and 12 months post-treatment. Significant pain relief was defined as 50% or more, whereas significant improvement in disability score was defined as a reduction of 40% or more. The percentage of patients with significant pain relief of 50% or greater at 12 months was 79% in Group I and 81% in Group II. Reduction of Oswestry scores of at least 40% was seen in 83% of the patients in Group I and 91% in Group II. The

    As an important representative of modern Chinese medicine, traditional Chinese medicine (TCM) injzection has become an indispensable part of the Chinese medicine industry. However, its development is now restricted by the bottleneck of insufficient core competitiveness, low-level research and production, even injection quality and the safe use are not guaranteed. Thus, it is urgent to reevaluate post-marketing TCM injection generally and to make secondary development. Under current circumstances, taking major brands which have good clinical and market foundation, as well as research value, as the main subject of cultivation and evaluation is an important approach to innovative development of TCM injection industry. Unlike oral proprietary Chinese medicine, the cultivatation of major brands of TCM injection needs higher technical support, quality standards and more timely feedback. Therefore, a post-market integral evaluation system adaptive to TCM injection is required. This article discussed some key points on the construction of a post-market integral evaluation system of TCM injection in three levels: optimizing evaluation methods, building synergistic innovation platforms which combine the medical research institutions and pharmaceutical enterprises, and finally constructing the integral evaluation system. A "five to one" structure has been proposed to enhance TCM injection effectiveness, safety and adaptability on the whole, which are from the following aspects: mechanism research, clinical evidence validation, literature information mining, sustainable development of resources and industrialization operation.

    A rapid, selective and sensitive UPLC-MS/MS assay was established to determine the plasma concentrations of four steroidal saponins. Sprague-Dawley rats were allocated to four groups which were orally administered Anemarrhena asphodeloides extracts (ASE), ASE combined with macromolecular fraction (ASE-MF), ASE combined with small molecule fraction (ASE-SF) and ASE combined with small molecule and macromolecular fraction (ASE-SF-MF) containing approximately the same dose of ASE. At different time points, the concentration of timosaponin BII, anemarsaponin BIII, timosaponin AIII and timosaponin E1 in rat plasma were determined and main pharmacokinetic parameters including Cmax, Tmax, T1/2, AUC were calculated using the DAS 3.2 software package. The statistical analysis was performed using the Student's t-test with p < 0.05 as the level of significance. MF had no effect on the pharmacokinetic behaviors and parameters of four steroidal saponins. It was found that Cmax and AUC of four steroidal saponins in group ASE-SF and ASE-SF-MF, were significantly increased compared with those in group ASE. These results indicate that SF in A. asphodeloides extracts could increase the absorption and improve the bioavailability of the steroidal saponins.

    To assess the prevalence of gastroprotective agent prescription in patients treated with non-steroidal anti-inflammatory drugs in France and to analyze the determinants of this prescription. A cross-sectional observational study was performed in 2576 patients treated with non-steroidal anti-inflammatory drugs recruited prospectively in the French primary care system. Thirty-nine percent of the patients (n=1002) received gastroprotective agents, mostly proton pump inhibitors (99.5%). In patients with a single risk factor, the gastroprotection rates were: 50% for age>65, 67% for concurrent use of corticosteroids or antithrombotics, and 87% and 100% for history of uncomplicated and complicated gastroduodenal ulcers. In patients without risk factors, gastroprotective agents were prescribed in 31.8%. Among them, two thirds had symptoms of gastro-oesophageal reflux or history of non-steroidal anti-inflammatory drug intolerance or dyspepsia. Conversely, 40% (n=256) of at-risk non-steroidal anti-inflammatory drug users did not receive gastroprotective agents. Gastroprotection was significantly associated with history of gastroduodenal ulcer (OR: 8.2; 95%CI: 4.3-15.6) or history of non-steroidal anti-inflammatory drug intolerance (OR: 6; 95%CI: 4.5-8.1), gastro-oesophageal reflux (OR: 6; 95%CI: 4.4-8.2), dyspepsia (OR: 5.2; 95%CI: 3.7-7.5), concurrent gastrotoxic treatment (OR: 3.3; 95%CI: 1.9-5.6) and age>65 (OR: 3; 95%CI: 2.3-4.1). Despite widespread recommendations, gastroprotection is still largely underprescribed in patients at risk of gastrointestinal non-steroidal anti-inflammatory drug complications in France. Only half of non-steroidal anti-inflammatory drug users above 65 years are prescribed gastroprotective agents. Copyright © 2010 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

    Brassinosteroids (BS) are the first group of steroid-hormonal compounds isolated from and acting in plants. Among numerous physiological effects of BS growth stimulation and adaptogenic activities are especially remarkable. In this review, we provide evidence that BS possess similar types of activity also beyond plant kingdom at concentrations comparable with those for plants. This finding allows looking at steroids from a new point of view: how common are the mechanisms of steroid bioregulation in different types of organisms from protozoa to higher animals.

    Following its secretion mainly by the adrenal glands, dehydroepiandrosterone (DHEA) acts primarily in the cells/tissues which express the enzymes catalyzing its intracellular conversion into sex steroids by the mechanisms of intracrinology. Although reliable assays of endogenous serum steroids are now available using mass spectrometry (MS)-based technology, sample preparation from tissue matrices remains a challenge. This is especially the case with high lipid-containing tissues such as the brain. With the combination of a UPLC system with a sensitive tandem MS, it is now possible to measure endogenous unconjugated steroids in monkey brain tissue. A Shimadzu UPLC LC-30AD system coupled to a tandem MS AB Sciex Qtrap 6500 system was used. The lower limits of quantifications are achieved at 250 pg/mL for DHEA, 200 pg/mL for 5-androstenediol (5-diol), 12 pg/mL for androstenedione (4-dione), 50 pg/mL for testosterone (Testo), 10 pg/mL for dihydrotestosterone (DHT), 4 pg/mL for estrone (E1) and 1 pg/mL for estradiol (E2). The linearity and accuracy of quality controls (QCs) and endogenous quality controls (EndoQCs) are according to the guidelines of the regulatory agencies for all seven compounds. We describe a highly sensitive, specific and robust LC-MS/MS method for the simultaneous measurement of seven unconjugated steroids in monkey brain tissue. The single and small amount of sample required using a relatively simple preparation method should be useful for steroid assays in various peripheral tissues and thus help analysis of the role of locally-made sex steroids in the regulation of specific physiological functions.

    To evaluate color Doppler imaging (CDI) as the primary imaging modality in the diagnosis of pediatric orbital capillary hemangioma. This is a retrospective study of 36 consecutive cases of orbital capillary hemangiomas between January 2006 and July 2011. Data on demographic details, clinical findings, gray-scale ultrasonography, CDI characteristics, treatment, and follow-up period were reviewed. The mean age of onset was 7 weeks. Twenty-nine (81%) lesions presented as eyelid masses, whereas seven (19%) presented as exophthalmos. Nineteen (53%) tumors were located on the upper eyelid, seven (19%) on the lower eyelid, six (17%) in the medial canthus, and one on both upper and lower eyelids. Ultrasonography depicted a heterogeneous, well-defined, irregular tumor with a low or moderate echogenicity. All lesions presented with abundant color blood flow on CDI. The intralesional blood flow had a mean peak systolic velocity of 37.5 ± 24.5 cm/second, and a mean resistance index of 0.69 ± 0.16, representing a shift in the pulse Doppler toward high velocity and high resistance. After a single intratumoral injection of betamethasone, 18 cases (50%) resolved. Additionally, 15 (42%) and four (11%) cases resolved after two injections and three injections, respectively. Only three (8%) masses persisted after three injections within the follow-up period. The blood flow characteristics of CDI play a vital role in the differentiation of orbital capillary hemangiomas from other orbital lesions. The availability and lack of adverse effects of CDI enable its utilization in the early clinical diagnosis of pediatric orbital capillary hemangioma. Copyright © 2014. Published by Elsevier B.V.

    Anabolic steroid abuse is common among athletes and is associated with a number of medical complications. We describe a case of a 27-year-old male bodybuilder with multiple hepatic adenomas induced by anabolic steroids. He initially presented with tumor hemorrhage and was treated with left lateral hepatic segmentectomy. Regression of the remaining tumors was observed with cessation of steroid use. However, 3 years and a half after his initial hepatic segmentectomy, he presented with recurrent tumor enlargement and intraperitoneal hemorrhage in the setting of steroid abuse relapse. Given his limited hepatic reserve, he was conservatively managed with embolization of the right accessory hepatic artery. This is the first reported case of hepatic adenoma re-growth with recidivistic steroid abuse, complicated by life-threatening hemorrhage. While athletes and bodybuilders are often aware of the legal and social ramifications of steroid abuse, they should continue to be counseled about its serious medical risks.

    This study focused on the reasons for practicing bodybuilding and the use of anabolic steroids, as well as the social representations and uses of the body among bodybuilding steroid users. This ethnographic study involved participant observation in middle and lower-class bodybuilding gyms in Salvador, Bahia State, Brazil, and 43 in-depth interviews with steroid users. Aesthetic reasons are the main motivation for bodybuilding and steroid use in both middle and lower-class users. Dissatisfaction with one's real body as compared to the ideal standard flaunted by the mass media, fear of being devalued or shunned by one's peer groups, the symbolic capital associated with a 'pumped-up' body, and the sense of immediacy in obtaining results all contributed to steroid use. Preventive campaigns are needed, targeting young people and combining a critical view and deconstruction of the values assigned to the body by consumer society, counteracted by high-quality information on the health risks associated with anabolic steroid use.
