    The aim of the present work was to investigate the potential of microemulsions for the buccal administration of triamcinolone acetonide. Microemulsions were developed by the construction of pseudoternary phase diagrams, using the aqueous titration method. Among all microemulsions prepared and tested for stability, three were selected and submitted to characterization and in vitro permeation/retention experiments, using pig esophageal epithelium, an accepted model of the buccal mucosa. Furthermore, one microemulsion was added of excipients (stearylamine, CTAB and chitosan) able to alter the charge of droplets. The results obtained show that the permeation of triamcinolone acetonide across pig esophageal epithelium was not influenced by the droplet size nor by the composition, but only by the presence of chitosan, polysaccharide able to increase the transport across mono and stratified epithelia. The determination of the permeation parameters allowed us to show that chitosan acts on the diffusion parameter across the tissue and not on the partitioning parameter; for the same reason the tissue retention of triamcinolone acetonide was not modified. Triamcinolone flux (2.6 μg cm -2  h -1 ) was too low to make systemic administration feasible (dose required 2.5 to 60 mg/day). The amount of triamcinolone acetonide recovered in the mucosa after only 10 min. of microemulsion application was much higher than after overnight application of the commercial paste Omicilon® A. This suggests that triamcinolone acetonide microemulsions can be an interesting alternative to the commercial formulation to treat diseases of the buccal mucosa. Owing to the fast uptake by the tissue, the formulation can be used as a mouthwash. Copyright © 2018 Elsevier B.V. All rights reserved.

    The aim of the study was to evaluate the efficacy of intralesional triamcinolone acetonide injection in primary and recurrent chalazion. The study included 30 patients with primary and recurrent chalazion (37 cases) and 24 patients as a control group. Patients with primary and recurrent chalazion received intralesional injection of 0.1 to 0.2 mL triamcinolone acetonide (40 mg/mL). Control group received intralesional injection of 0.1 to 0.2 mL 0.9% NaCl. Data on the lesion size, including digital color photography, lesion regression or recurrence, and complete ophthalmic examination were recorded at the time of injection and after a week or two until resolution or surgical excision. Success was defined as at least 80% decrease in size with no recurrence. Resolution of the lesion was found in 35 cases after one or two injections, with a mean time to resolution of 15.27 +/- 6.12 days. Subcutaneous injection of the steroid triamcinolone acetonide in primary and recurrent chalazion appears to be a simple and efficacious therapeutic option for chalazion.

    The study is a prospective blinded randomised controlled trial to compare the efficacy of triamcinolone acetonide, bupivacaine or in combination in managing pain after lumbar discectomy. Patients undergoing primary single-level lumbar discectomy were randomised. Triamcinolone acetonide, bupivacaine or in combination was instilled at the nerve root as decompression. Preoperative, day 1 and 6 weeks pain score, 24-h postoperative opiate requirements and duration of inpatient stay were recorded. Data was analysed using Mann-Whitney test for statistical significance. 100 patients were recruited. A significant difference was noted in day one postoperative mean pain score, mean 24-h opiate requirement and mean inpatient stay in the triamcinolone acetonide and bupivacaine group. At 8 weeks postoperatively, no significant differences were seen in the pain score in all groups. Significant postoperative pain reduction and opiate requirements in the first 24 h, and significantly shortened duration of inpatient stay were achieved in the triamcinolone acetonide and bupivacaine group compared with other groups.

    To evaluate the effect of intravitreal injection of triamcinolone acetonide(IVTA) combining with retinal laser treating for diabetic macular edema(DME). Twenty five patients(32 eyes) with DME who has microangioma in macula lutea were randomly divided into group A, B,C and D(8 eyes each group). Eyes in group A were treated with laser photocoagulation. Eyes in group B were treated with multiplier-532 laser photocoagulation and transpupillary thermotherapy. Eyes in group C were treated with multiplier-532 laser photocoagulation and intravitreal triamcinolone acetonide. Eyes in group D were treated with multiplier-532 laser, transpupillary thermotherapy plus triamcinolone acetonide injection. Intravitreal injection of 4 mg triamcinolone acetonide was done 1 week after laser photocoagulation in group C and D. The visual acuity, intraocular pressure, macular thickness (foveal thickness) of the eyes in 4 groups were observed before and 1, 3 and 6 months after treatment. The visual acuity, intraocular pressure and foveal thickness of the 4 groups before treatment showed no significant difference(p> ). The visual acuity, intraocular pressure, macular thickness of eyes in group A, B were better than those of group C, D at 1, 3 and 6 months after treatment, and they had significant difference(p0.05). The effect of laser photocoagulation and intravitreal triamcinolone acetonide, laser photocoagulation combining with transpupillary thermotherapy plus triamcinolone acetonide injectionvisual treating for DME was better than laser photocoagulation alone, laser photocoagulation combining with transpupillary thermotherapy.

    A radioimmunoassay (RIA) was developed for the detection of triamcinolone acetonide (TAAc) in equine blood plasma. These antibodies exhibited cross reactions of 0,015% with cortisol and of 0,1% with other endogenous glucocorticoids. Four different synthetic corticosteroids interfered in a range of 0,21 to 0,93%. In vitro 86 of TAAc could be recovered. This method proved sufficient reproducibility down to a limit of 131,7 fmol/ml = 57,2 pg/ml. The TAAc RIA is suitable for the detection of a TAAc application particularly during the 1st day p.i. The results may obtain a higher limit of confidence by the simultaneous demonstration of cortisol suppression. By the use of this test more detailed conclusions may be drawn about presence and duration of a pharmacodynamic action originating from the TAAc depot. (orig./TRV) [de

    Tendinopathies are often empirically treated with oral/topical nonsteroidal anti-inflammatory medications and corticosteroid injections despite their unclear effects on tendon regeneration. Recent studies indicate that tendon progenitors exhibit stem cell-like properties, i.e., differentiation to osteoblasts, adipocytes, and chondrocytes, in addition to tenocytes. Our present study aims at understanding the effects of triamcinolone acetonide and diclofenac on tenocytic differentiation of mesenchymal stem cells. The murine fibroblast C3H10T1/2 cell line was induced to tenocytic differentiation by growth differentiation factor-7. Cell proliferation and differentiation with the exposure of different concentrations of triamcinolone acetonide and diclofenac were measured by WST-1 assay and real-time polymerase chain reaction analysis, respectively. Cell proliferation was decreased in a concentration-dependent manner when exposed to triamcinolone acetonide and diclofenac. In addition to tenocytic differentiation, adipocyte formation was observed, both at gene expression and microscopic level, when the cells were exposed to triamcinolone acetonide or high concentrations of diclofenac. Our results indicate that triamcinolone acetonide and diclofenac might alter mesenchymal stem cell differentiation in a nonfavorable way regarding tendon regeneration; therefore, these medications should be used with more caution clinically.

    Full Text Available Objective: To evaluate the effectiveness of steroid and 5-fluorouracil (5-FU injection combination for keloid management. Methods: A 22-year-old female patient was presented with recurrent skin lesions. The skin lesions first appeared 10 years prior to consultation, had been surgically excised, and were given triamcinolone acetonide injection. However, no improvement was observed. A decision was made to use and evaluate treatment using an intralesional 4 mg (0.1 ml of 40 mg/ml triamcinolone acetonide and 45 mg (0.9 ml of 50 mg/ml 5-FU injection combination for 5 weeks. Results: Clinical improvements were observed in the third week as the lesions softened and pruritic sensation dinimished. At the end of the fifth week, improvements in the form of keloid lesion flattening and size reduction were observed. Conclusions: Intralesional injection using a combination of triamcinolone acetonide and 5-fluorouracil is effective for keloid lesion treatment.

    Full Text Available Purpose: To compare the results of intracameral dexamethasone and intracameral triamcinolone acetonide injection in patients that underwent cataract surgery with phacoemulsification. Materials and Methods: Sixty eyes of 60 patients that underwent cataract surgery with phacoemulsification were randomized into two groups. Preoperative visual acuity of all patients was 0.5 or lower and intraocular pressures were under 21mmHg. After surgery, eyes in group 1 (30 eyes were injected with 0.4 mg/0.1 ml dexamethasone into the anterior chamber, and eyes in group 2 (30 eyes were injected with 2 mg/0.05 ml triamcinolone acetonide into the anterior chamber. All eyes received standard postoperative prednisolone acetate and moxifloxacin eye drops. The biomicroscopic evaluation, visual acuity, and intraocular pressure measurements were done at baseline (preoperatively and on postoperative days 1, 7 and 30. Results: There were no statistically significant differences in mean visual acuity, the amount of anterior cells and flare between the two groups (P ≥ 0.05. Mean intraocular pressure values at postoperative first day were significantly higher in group 2 than in group 1 (P = 0.009. The mean intraocular pressures on days 7 and 30 after surgery were not statistically different between the two groups (P ≥ 0.05. Conclusions: Intracameral dexamethasone and intracameral triamcinolone acetonide were similarly effective in controlling postoperative inflammation following phacoemulsification. However, the intraocular pressures on postoperative first day were higher in patients receiving intracameral triamcinolone acetonide. The highest intraocular pressure in triamcinolone acetonide group was 24 mmHg, and stabilized in a few days, therefore using triamcinolone acetonide may impose a minimal risk to patients. Nevertheless, intracameral dexamethasone seems to be a better alternative to apply at the end of surgery to suppress the inflammation during the first 24 hours.

    Subacromial impingement is a common cause of shoulder complaints in general practice. When the initial treatment with acetaminophen and low dose Non Steroidal Anti Inflammatory Drugs fails, triamcinolone acetonide injections are commonly used. Triamcinolone acetonide injections are effective at four to six weeks. Little is known about the pain relief effect of triamcinolone acetonide injections in the first days after injection and the effect of repeated injection. In this study we investigate the effect of triamcinolone acetonide injections compared to hyaluronic acid and NaCl injections using a pain diary. 159 Patients recruited for an RCT comparing the effect of subacromial injections of triamcinolone acetonide, hyaluronic acid and sodium chloride (NaCl) were used in this study. They were blinded for their treatment and could receive up to three injections. Primary outcome consisted of the patient perceived pain on a VAS score recorded on a daily basis during 21 days following injection. Secondary outcome consisted of the amount of taken escape medication following injection and adverse effects. All patients received the first injection. 150 patients also received the second and third injections. 97% Of the paper and pencil pain diaries were returned for data analysis.The triamcinolone acetonide group showed the largest decrease in pain on the VAS scores after injection compared to the hyaluronic acid and NaCl group in the first week after injection. The reduction in pain was best achieved after the first injection, the second triamcinolone acetonide injection showed a further reduction in pain. The third triamcinolone acetonide injection only showed a slight improvement in pain reduction. In this study we could show a booster effect in pain reduction after repeated triamcinolone acetonide injection. The triamcinolone acetonide group showed a faster reduction in pain after injection compared to the hyaluronic acid and NaCl group. The effect was best seen after

    The aim of the study was to compare the effect of submucosal injection of dexamethasone and triamcinolone acetonide on postoperative pain, swelling, and trismus occurring after impacted mandibular third molar surgery. A total of 78 patients (aged 18 to 35) with asymptomatic, unilateral, impacted mandibular third molar, and without any systemic disease were included in this study. Patients were divided into three groups randomly (control, dexamethasone, and triamcinolone acetonide). In the experimental groups, dexamethasone and triamcinolone acetonide were injected into submucosa at about 1 cm above the surgical area submucosally. The control group of patients did not take any drug submucosally but the same surgical procedure was applied. Pain evaluation was performed by visual analog scale (VAS). Swelling was measured using a flexible standard ruler measuring the dimensions of the axes between certain points on the face. For trismus evaluation, maximum mouth opening was measured. Measurements taken on the preoperative, and on postoperative first, third, and seventh days were compared with each other and statistically evaluated. There were statistically significant differences between the control and experimental groups on the different days of the postoperative period. The effect of triamcinolone acetonide on pain started on the first day postoperatively and the effect of triamcinolone acetonide on trismus and pain was better than other groups at the third and seventh days. However, there was no statistically significant difference between the effects of dexamethasone and triamcinolone acetonide regarding postoperative complications. The submucosal injection of dexamethasone or triamcinolone acetonide might be an effective treatment for postoperative discomfort occurring following impacted mandibular third molar surgery, and triamcinolone acetonide could be applied as an alternative to dexamethasone.

    Background Accumulating evidence on the causal role of spinal cord microglia activation in the development of neuropathic pain after peripheral nerve injury suggests that microglial activation inhibitors might be useful analgesics for neuropathic pain. Studies also have shown that polyamidoamine dendrimer may function as a drug delivery vehicle to microglia in the central nervous system. In this regard, we developed polyamidoamine dendrimer-conjugated triamcinolone acetonide, a previously identified microglial activation inhibitor, and tested its analgesic efficacy in a mouse peripheral nerve injury model. Result Polyamidoamine dendrimer was delivered selectively to spinal cord microglia upon intrathecal administration. Dendrimer-conjugated triamcinolone acetonide inhibited lipoteichoic acid-induced proinflammatory gene expression in primary glial cells. In addition, dendrimer-conjugated triamcinolone acetonide administration (intrathecal) inhibited peripheral nerve injury-induced spinal cord microglial activation and the expression of pain-related genes in the spinal cord, including Nox2, IL-1β, TNF-α, and IL-6. Dendrimer-conjugated triamcinolone acetonide administration right after nerve injury almost completely reversed peripheral nerve injury-induced mechanical allodynia for up to three days. Meanwhile, dendrimer-conjugated triamcinolone acetonide administration 1.5 days post injury significantly attenuated mechanical allodynia. Conclusion Our data demonstrate that dendrimer-conjugated triamcinolone acetonide inhibits spinal cord microglia activation and attenuates neuropathic pain after peripheral nerve injury, which has therapeutic implications for the treatment of neuropathic pain.

    Full Text Available Active serpiginous choroiditis (SC is a vision-threatening condition which requires intensive treatment using corticosteroids and/or immunosuppressives, especially if the lesions are involving or encroaching on the macula. Use of oral and intravenous high-dose steroids are contraindicated in uncontrolled diabetics. Intravitreal steroid delivers a localized dose in such situations. This case report highlights the efficacy of reduced dose of intravitreal triamcinolone acetonide (2 mg in the treatment of active SC.

    To compare the efficacy of subcutaneous extralesional triamcinolone acetonide injection versus conservative treatment for chalazion. Randomised controlled trial. Eye clinics of two regional hospitals in Hong Kong. Patients over 18 years old presenting with primary chalazion were randomised into two groups. In group 1, 12 patients were treated with lid hygiene, warm compresses, and chloramphenicol 1% ointment 4 times a day. In group 2, 16 patients were treated with 0.3 mL triamcinolone acetonide (10 mg/mL) injection to the subcutaneous tissue extralesionally via the percutaneous route. Exclusion criteria were: acutely infected chalazion with preseptal cellulitis, recurrent chalazion, small chalazion (chalazion. Size of chalazion, recurrence of chalazion, intra-ocular pressure, and complications from treatment, including skin pigmentary change or atrophy and pyogenic granuloma. There was a clinically and statistically significant difference between the success rates in group 1 (58.3%) and group 2 (93.8%). In group 1, the mean prior duration of chalazion before treatment was significantly shorter in success cases than in failed cases. One patient with multiple chalazia in group 2 developed hypopigmentary skin changes at one treatment site. Subcutaneous extralesional triamcinolone acetonide injection was more effective than conservative treatment for chalazion.

    Full Text Available We report a case of a human leukocyte antigen B27 (HLA-B27-negative patient with cystoid macular edema (CME and ankylosing spondylitis (AS after treatment with triamcinolone acetonide. The patient complained of deterioration of visual acuity of the right eye during the last 10 days. At presentation visual acuity of the right eye was 0.2, and the ophthalmic examination did not reveal any sign of active uveitis. Fluorescein angiography (FA and ocular coherent tomography (OCT showed CME. The left eye was normal with a visual acuity of 0.9. Eight weeks after intravitreal injection of triamcinolone acetonide, visual acuity improved to 0.8 and OCT revealed regression of macular edema. Six months later no recurrence was observed. Our case report indicates for the first time that CME may occur in AS independently of the presence of HLA-B27 and intraocular inflammation. Intravitreal use of triamcinolone acetonide can reduce macular edema and restore visual acuity.

    Iatrogenic Cushing's syndrome is a well-known adverse effect of glucocorticoids. It usually develops after prolonged exposure to excessive amounts of synthetic glucocorticolds. The development of iatrogenic Cushing's syndrome (ICS) after a single and low dose of synthetic glucocorticoid is an exceptional event. Up to now, only a few number of cases have been associated with triamcinolone acetonide and they have always been related to local administration. We report, for the first time, a patient who developed ICS after a single low dose of parenterally (im) administered triamcinolone acetonide. She was a 45-yr-old woman who referred to us because of cushingoid appearance, whose hormonal determinations were suggestive of secondary adrenal insufficiency. Clinical features were developed one month after the administration of a 40 mg single-dose of im triamcinolone acetonide because of acute laryngitis. Endocrinological evaluation confirmed the hypothalamic-pituitary-adrenal (HPA) axis suppression. Eight months later, cushingoid phenotype had completely disappeared and HPA function had spontaneously recovered. We review clinical features and comment on the possible pathogenic mechanisms of this particular and new form of ICS.

    Results of previous studies on the benefits of ocular drug delivery using polymeric mucoadhesive nanoparticles suggested longer presence and better penetration of nanoparticles, and, thus, increased effect and bioavailability of drugs entrapped in nanoparticles. In this study, a novel polymer, poly β-amino ester, was used for the preparation of triamcinolone acetonide-loaded nanoparticles using a modified emulsification/solvent diffusion method. Mucoadhesiveness studies, in vitro drug release, x-ray powder diffraction, differential scanning calorimetry, and scanning electron microscopy were used for physicochemical characterization of nanoparticles. Thirty-six hours after inducing uveitis by intravitreal injection of a lipopolysaccharide, sampling from the aqueous humor was done and inflammatory factors, such as cell, protein, nitric oxide, and prostaglandin E2, were compared. Nanoparticles with a mean size of 178 nm and drug loading of 5.3% were prepared and used for in vivo studies in rabbits with uveitis. Higher anti-inflammatory effect was observed for polymeric nanoparticles of triamcinolone acetonide compared with microparticles of prednisolone acetate and triamcinolone acetonide, and an equal effect compared with subconjunctival injection of triamcinolone acetonide in terms of inhibiting inflammation and inflammatory mediators. It can be concluded that polymeric nanoparticles of triamcinolone acetonide will provide as good an anti-inflammatory effect as the subconjunctival injection method and are better compared with other drug delivery systems.

    To assess the effect of intraoperative intravitreal injection of triamcinolone acetonide on the central macular thickness, visual outcomes, and development of cystoid macular edema (CME) after phacoemulsification in diabetic patients. Farabi Eye Hospital, Tehran, Iran. In this prospective randomized controlled study, patients with diabetes were randomly assigned to a treatment group, which received an intravitreal injection of triamcinolone acetonide at the end of phacoemulsification, and a control group, which had routine phacoemulsification. Visual acuity, center-point thickness, central 1.0 mm subfield mean thickness, CME development, and diabetic retinopathy progression were compared between the 2 groups 1, 3, and 6 months postoperatively. The treatment group comprised 20 eyes and the control group, 21 eyes. There was no statistically significant difference between the 2 groups in the mean corrected distance visual acuity at any follow-up examination (P>.05). The mean change in center-point thickness and central 1.0 mm subfield mean thickness was statistically significantly lower in the treatment group than in the control group at all follow-up visits (P<.05). Four eyes in the control group and no eye in the treatment group developed CME (P = .059). Three eyes (15%) in the treatment group developed an intraocular pressure rise that was managed by topical medication. Intravitreal injection of triamcinolone reduced the amount of increase in center-point thickness and central 1.0 mm subfield mean thickness after phacoemulsification in eyes of diabetic patients. Although it also reduced the incidence of CME, it had no effect on visual acuity gain. (c) 2010 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

    International Nuclear Information System (INIS)

    In this paper a method for the radioimmunological determination of triamcinolone acetonide (TAAc) in plasma is described. The antiserum used in the radioimmunological determinations showed high specifity for TAAc; the minimal detectable amount was 0.2 ng. The course of the plasma concentrationtime curve of TAAc after intravenous injection into rats was analysed. The concentration of TAAc in the blood of the patients after topical application of the drug is very low. No detectable amount of TAAc was found in the blood of out-patients. Hospitalized patients treated with TAAc under plastic occlusion showed plasma levels ranging from 0.8 to 3.4 ng/ml. This level remained constant throughout the treatment. (orig.) 891 AJ [de

    Full Text Available Macular edema (ME is one of the eventual outcomes of various intraocular and systemic pathologies. The pathogenesis for ME is not yet entirely understood; however, some of the common risk factors for its development have been identified. While this investigation will not discuss the numerous etiologies of ME in detail, it appraises the two most widely studied delivery modalities of intraocular corticosteroids in the treatment of ME—intravitreal injection (IVI and sub-Tenon’s infusion (STI. A thorough review of the medical literature was conducted to identify the efficacy and safety of IVI and STI, specifically for the administration of triamcinolone acetonide (TA, in the setting of ME in an attempt to elucidate a preferred steroid delivery modality for treatment of ME.

    Many different non systemic corticosteroid administrations can cause iatrogenic Cushing's Syndrome (CS). We herein report a case series of iatrogenic CS from keloid scars treatment and aesthetic regimen called mesotherapy. Our first patient developed CS after having exceeded recommended dose of intralesional injection of Triamcinolone Acetonide (TAC). Second case presented with CS followed by unidentified mesotherapy treatment for local fat reduction. Subcutaneous injections of dexamethasone were found to be the part of mesotherapy regimen in one case. Physicians should be insightful in prescribing TAC especially in those patients who have high predisposing factors for developing CS. In the same way, off-label mesotherapy combine with corticosteroid can lead to iatrogenic CS and Hypothalamic-Pituitary-Adrenal (HPA) axis suppression. Currently, there are no standard guidelines for mesotherapy treatment. Therefore, further clinical trials on dosage, duration and effective combination of mesotherapy regimens are needed to increase safety uses.

    Interpretation and conclusion Topical tacrolimus 0.03% ointment induced better initial therapeutic response than triamcinolone acetonide 0.1 % ointment. However, relapses occurred in two subjects in group ′A′ and three subjects in group ′B′ after the cessation of the respective treatments. Nevertheless, at present topical tacrolimus may be a valuable addition to the already existing therapeutic modalities for treating subjects with OLP.

    Full Text Available PURPOSE: To evaluate the inflammatory response in the choroid, retina and vitreous in rabbit eyes underwent cryotherapy followed by intravitreal triamcinolone acetonide and to compare with those underwent cryotherapy followed by intravitreal injection of saline solution. METHODS: This is a prospective case-control study. Surgical procedures were performed in eleven rabbits. Two animals were excluded because they did not complete the postoperative period or had intraoperative or postoperative complications. All rabbits underwent superior temporal peritomy and transscleralcryotherapy in both eyes. After cryotherapy, animals received intravitreal injection of triamcinolone acetonide in one eye and saline solution in the fellow eye. Animals were sacrificed seven days after the procedure and their eyes were enucleated. Histological sections of eyeballs were prepared and the vitreous humor was aspirated. The count of inflammatory cells was performed by light microscopy. RESULTS: Histological sections of both eyes of nine rabbits were analyzed. Inflammatory cells were found only in the choroid. There was no statistically significant difference in the number of inflammatory cells between the two groups, regardless of cell type analyzed. CONCLUSION: This study showed no statistically significant difference between the use or absence of intravitreal triamcinolone acetonide in the inflammatory response to cryotherapy in rabbit eyes. Studies with larger samples are needed to confirm the trend of this paper.

    The use of triamcinolone acetonide (TA) in performance horses necessitates establishing appropriate withdrawal times prior to performance. To describe the plasma pharmacokinetics of TA and time-related urine and synovial fluid concentrations following i.m. and intra-articular administration to exercised Thoroughbred horses. Block design. Twelve racing fit adult Thoroughbred horses received a single i.m. administration of TA (0.1 mg/kg bwt). After an appropriate washout period, the same horses then received a single intra-articular TA administration (9 mg) into the right antebrachiocarpal joint. Blood, urine and synovial fluid samples were collected prior to, and at various times, up to 60 days post drug administration and analysed using liquid chromatography-mass spectrometry. Plasma data were analysed using noncompartmental analysis. Maximum measured plasma TA concentrations were 0.996 ± 0.391 at 13.2 h and 1.27 ± 0.278 ng/ml at 6.5 h for i.m. and intra-articular administration, respectively. The plasma terminal elimination half-life was 11.4 ± 6.53 and 0.78 ± 1.00 days for i.m. and intra-articular administration, respectively. Following i.m. administration, TA was below the limit of detection (LOD) by Days 52 and 60 in plasma and urine, respectively. Following intra-articular administration TA was undetectable by Day 7 in plasma and Day 8 in urine. Triamcinolone acetonide was also undetectable in any of the joints sampled following i.m. administration and remained above the limit of quantitation (LOQ) for 21 days following intra-articular administration. This study extends previous studies describing the pharmacokinetics of TA following i.m. and intra-articular administration to the horse and suggests that plasma and urine concentrations are not a good indicator of synovial fluid concentrations. Furthermore, results of this study supports an extended withdrawal time for TA given i.m. © 2013 EVJ Ltd.

    Full Text Available Objectives: To investigate the effect of intravitreal triamcinolone acetonide (IVTA used for the macular edema on intraocular pressure (IOP and to determine the risk factors for IOP elevation. Materials and Methods: This retrospective study included 93 eyes of 85 patients who had 4 mg intravitreal triamcinolone injection. Of the 85 patients, 56 (65.8% had diabetic macular edema, 22 (25.8% had branch retinal, and 7 (8.2% had central retinal vein occlusion. IOP changes after injection as well as the relation between IOP elevation and age, sex, lens status, etiology of macular edema, baseline IOP were evaluated. Results: Fourty-six male and 39 female patients with mean age 61.58±9.5 years were evaluated. IOP was recorded to be >24 mmHg in 30 eyes (32.2% at follow-up visit after an average of 7.5 weeks. Normalization of IOP with medication was achieved in all IOP elevated eyes. Fifteen of 29 eyes (51.7% with vein occlusion and 15 of 64 eyes (23.3% with diabetic macula edema had IOP elevation (p=0.01. Twenty-six of 73 phakic (35.6% and 4 of 20 pseudophakic eyes (20% had IOP >24 mmHg (p=0.16. There was no association between IOP elevation and sex (p=0.33. Baseline IOP was 16.47±2.8 mmHg in eyes which had elevated IOP and 14.78±2.4 mmHg in the remaining. There was significant relation between IOP elevation and baseline IOP level (p=0.01. Conclusion: Elevated IOP is common side effect after IVTA, but normalization is usually achieved by topical medication. Patients with baseline IOP ≥15 mmHg and vein occlusion have higher risk for IOP elevation. (Turk J Ophthalmol 2015; 45: 86-91

    Subacromial bursitis is caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon from the overlying coraco-acromial ligament and acromion. While multiple cytokines are implicated, interleukin-1 beta appears to play a prominent role. Rilonacept, an interleukin-1 trap, may be an alternative to corticosteroid injection for the management of this condition. This single center, randomized, non-inferiority, unblinded study recruited 33 subjects over 9 months. Twenty subjects received 160mg intrabursal injection of rilonacept and 13 received a 6mL mixture of lidocaine, bupivacaine, and 80mg triamcinolone acetonide. QuickDASH, subject reported pain, and adverse events were recorded at time of injection, 2 days later, 2 weeks later, and 4 weeks later. Primary outcome was improvement in QuickDASH 4 weeks post-injection. Secondary outcomes were improvement in subject reported pain and occurrence of adverse events at 4 weeks. Both study groups were equally matched for age, gender, ethnicity, and site of bursa injection. Both medications demonstrated a statistically significant improvement in QuickDASH 4 weeks post-injection, but triamcinolone acetonide injection offered greater improvement (P=0.004). Both medications demonstrated improvement in subject reported pain but between group comparison at 4 weeks showed that triamcinolone was superior (P=0.044). No statistically significant differences in adverse events were noted between groups, but subjects who received rilonacept experienced more episodes of diarrhea and headache. While improvement in QuickDASH and pain was noted with a single intrabursal injection of rilonacept at 4 weeks, injection with triamcinolone acetonide was more efficacious.

    Spasticity is a common feature in patients with multiple sclerosis (MS). Although options have broadened over the last years, there are still patients with no response to common therapeutic agents. Intrathecal administered triamcinolone acetonide (TCA) has been tested for spasticity in patients with MS. However, the long run effects are not known so far. The aim of this study was to evaluate the effects of repeated cycles of intrathecal TCA instillations on clinical parameters. A total of 54 patients with clinically definite MS and no response to commonly utilized antispastic drugs were enrolled. TCA was administered every 3 months for a period of 9 months. Clinical assessments including spasticity, disability (EDSS), mobility (walking distance, and timed 25-foot walk), bladder function, and quality of life were carried out prior to and at the end of each treatment cycle. Repeated TCA treatment led to repeated effects on spasticity (P spasticity or EDSS was not shown at end of the study. Effects diminished over 3 months. Repeated TCA instillations led to replicable effects on spasticity; subgroup analyses suggest that higher spasticity, more frequent treatments, and higher EDSS may lead to pronounced effects on spasticity and EDSS. Intrathecal TCA treatment was safe and no severe side effects occurred. We hypothesize a significant time dependence of re-administration of TCA and that an interval of 3 months between the treatments might be too long. © 2015 John Wiley & Sons Ltd.

    To investigate the effect of intravitreal triamcinolone acetonide injection on the resolution of subretinal fluid (SRF), and its correlation with visual outcome after scleral buckle (SB) surgery. A prospective consecutive case series was conducted in patients who underwent SB surgery for macula-off rhegmatogenous retinal detachment (RRD) at Farabi Eye Hospital from February 1, 2012 to August 30, 2013. Exclusion criteria included previous ocular surgery (e.g. primary surgical failure) except cataract surgery, recurrent retinal detachment, macular hole, epiretinal membrane, proliferative vitreoretinopathy grade C, history of trauma, other retinal diseases, and diabetes mellitus. Patients were assigned to two groups. In group 1, patients received 2 mg of intravitreal triamcinolone acetonide injection at the end of surgery while patients in group 2 received intravitreal balanced saline solution for balancing the intraocular pressure (IOP). Patients were followed up at 1 day, 1 week, 1 month, 2 months and 3 months after the surgery by best-corrected visual acuity (BCVA), slitlamp examination, indirect ophthalmoscopy and optical coherence tomography (OCT). OCT (Heidelberg Engineering, Heidelberg, Germany) was used at all visits except day 1 after the surgery. Student's t test and χ(2) tests were used for comparisons; p value ≤ 0.05 was considered significant. Sixty-two eyes of 62 patients were enrolled in the study. There were 33 male patients (53%) and 29 female patients (47%). The average age was 43.8 years (18-72 years). The mean duration of symptoms was 34.7 ± 46.8 days. There were 29 eyes in group 1 and 33 eyes in group 2. Twelve weeks after the operation, 25 patients (40%) had SRF beneath the macula, but there was no significant difference (p = 0.24, χ(2) test) between the two groups.

    Drug nanosuspensions (NSs) show a significant potential to improve loading and release properties of the poorly water soluble drug triamcinolone acetonide (TA) from poly(hydroxyethyl methacrylate) (pHEMA) soft contact lenses. In this work, TA NSs were developed by a controlled precipitation method using a fractional factorial Plackett-Burmann design. Poloxamer 407 (PL) and polyvinyl alcohol (PVA) as stabilizing agents were selected. NSs were characterized in terms of their drug content, particle size and morphology. Results indicate that all studied factors, except homogenization speed and sonication, have significant influence on the drug incorporation yield into NSs. Drug nanoparticles showed an interesting size that may be suitable for their incorporation into topical ocular drug delivery systems, as hydrogels. pHEMA hydrogels and daily-wear Hilafilcon B commercial contact lenses (SCLs) were employed to study TA loading capacity and drug release properties using NSs as loading system. Hydrogels have been synthesised by copolymerization of 2-hydroxyethyl methacrylate (HEMA) with methacrylic acid (MA) in accordance with a previous work (García-Millán et al., 2015). Both synthesised hydrogels and SCLs were characterized in terms of their mechanical and physical properties and TA loading and release properties. Selected TA NS was further characterized by studying its physical-chemical stability during the loading process. Results show that the use of TA NSs as loading medium significantly increases drug loading capacity and release of soft contact lenses in comparison with drug saturated solution. Synthesised pHEMA hydrogels and SCLs lenses have good properties as ophthalmic drug delivery systems, but SCLs load higher quantities of drug and release TA in shorter time periods than synthesised pHEMA hydrogel.

    To evaluate the rate of sterile endophthalmitis (SE) following intravitreal injection of three different formulations of triamcinolone acetonide (TA) in a single physician practice and also to assess the mean diameter and concentration of particles of the two TA formulations currently available commercially in the USA. It was hypothesized that TA formulations with smaller particles and/or greater concentrations would have a higher incidence of SE. Single-site, interventional case series in which the medical records of 392 consecutive eyes receiving intravitreal TA as Triesence(®), Kenalog(®)-40, or preservative-free TA between September 2008 and October 2013 were retrospectively reviewed for the incidence of SE. Particle sizing of TA formulations was conducted by an independent commercial laboratory. Five cases of SE were identified. The four cases of SE following Triesence(®) (4.6%) represented a rate significantly higher than the one case of SE following preservative-free TA (0.6%; P=0.049) and the 0% incidence rate of SE following Kenalog(®)-40 (P=0.0210). Triesence(®) had significantly smaller particles than Kenalog(®)-40 (P<0.0001). The rate of SE was the highest with the formulation of TA that had the smallest particle size and highest particle load (number of particles injected). The lowest rate of SE was seen with Kenalog(®)-40, the only TA formulation that contained a benzyl alcohol preservative. The data do not support a principal causative role of benzyl alcohol in the development of TA-induced SE. Instead, the data support the particle theory of TA-induced SE; however, larger-scale, multicenter studies are needed to confirm and expand on these findings.

    A high-performance liquid chromatography (HPLC) method with UV detection at 232 nm was developed and validated for the simultaneous determination of triamcinolone acetonide (TAA) and oxymetazoline hydrochloride (OXY) in nasal spray formulations. The chromatographic system consisted of a micro Bondapak CN column (150 mm x 3.9 mm), 5 microm particle size with a mobile phase composition of acetonitrile:ammonium acetate (pH 5.0, 20mM) (10:90, v/v) at a flow rate of 1.0 mL/min. Calibration curves were linear for both TAA and OXY in the concentration range of 2.5-25.0 microg/mL. The limit of detection and quantitation were 0.29 and 0.88 microg/mL for OXY and 0.24 and 0.73 microg/mL for TAA. The described method was further applied to the analysis and stability studies of two nasal spray formulations I and II prepared from TAA and OXY commercial nasal spray products. The stability of OXY and TAA in the commercial products and the nasal formulations I and II were analyzed after 30 days at room temperature and 30 days at 40 degrees C/60% relative humidity. The results of the stability study showed that OXY and TAA in the commercial nasal spray products and the nasal formulations I and II were stable at 20-25 degrees C (room temperature) but TAA was unstable at 40 degrees C/60% relative humidity. TAA exhibited more than 10% loss at 14 days in both the nasal formulations and in the commercial products. OXY showed increased degradation at 40 degrees C/60% relative humidity but <10%.

    Idiopathic bulbar urethritis (IBU) is characterized by hematuria ± dysuria without infection. Symptoms result from inflammation of the bulbar urethra, distal to external sphincter. IBU is difficult to manage and there is no recommended therapy. To determine whether instillation of triamcinolone acetonide is a useful treatment of IBU and its associated complications. Data were prospectively collected, for 22 months, on 14 consecutive patients presenting with terminal hematuria or blood spotting ± dysuria to a pediatric urology unit. Median age was 12 years (range: 10-15). Mean symptom duration was 13 months (range: 8-24). Normal baseline laboratory blood tests, urine cultures, and ultrasound assessments were seen in all; therefore, none were excluded on the basis of a known pathology. Follow-up telephone interviews, to assess symptom persistence and side effects, were performed at 6 weeks postintervention. The mean follow-up period was 15 months (range: 4-20). Visual confirmation of IBU was obtained cystoscopically and 40 mg of triamcinolone was instilled to the inflamed area under direct vision using an open-ended ureteral catheter. Symptoms resolution was the primary outcome. Repeat cystoscopic assessment ± triamcinolone instillation was recorded, as was the occurrence of complications. Seven patients (50%) required at least one further treatment. Overall complete or partial resolution was reported in 12/14 patients (85.7%). No side effects were reported. This small prospective series demonstrates that intraurethral instillation of triamcinolone seems to be a promising treatment option to alleviate inflammatory symptoms in majority of cases of idiopathic urethritis. Patient Summary: Fourteen boys with inflammation of the urethra, with no identifiable cause, were treated by topically triamcinolone, directly to the inflamed area. We demonstrate an 85.7% complete/partial resolution of symptoms with no side effects seen.

    Little is known about the underlying effects controlling in vitro-in vivo correlations (IVIVCs) for biodegradable controlled release microspheres. Most reports of IVIVCs that exist are empirical in nature, typically based on a mathematical relationship between in vitro and in vivo drug release, with the latter often estimated by deconvolution of pharmacokinetic data. In order to improve the ability of in vitro release tests to predict microsphere behavior in vivo and develop more meaningful IVIVCs, the in vivo release mechanisms need to be characterized. Here, two poly(lactic-co-glycolic acid) (PLGA) microsphere formulations encapsulating the model steroid triamcinolone acetonide (Tr-A) were implanted subcutaneously in rats by using a validated cage model, allowing for free fluid and cellular exchange and microsphere retrieval during release. Release kinetics, as well as mechanistic indicators of release such as hydrolysis and mass loss, was measured by direct analysis of the recovered microspheres. Release of Tr-A from both formulations was greatly accelerated in vivo compared to in vitro using agitated phosphate buffered saline +0.02% Tween 80 pH7.4, including rate of PLGA hydrolysis, mass loss and water uptake. Both microsphere formulations exhibited erosion-controlled release in vitro, indicated by similar polymer mass loss kinetics, but only one of the formulations (low molecular weight, free acid terminated) exhibited the same mechanism in vivo. The in vivo release of Tr-A from microspheres made of a higher molecular weight, ester end-capped PLGA displayed an osmotically induced/pore diffusion mechanism based on confocal micrographs of percolating pores in the polymer, not previously observed in vitro. This research indicates the need to fully understand the in vivo environment and how it causes drug release from biodegradable microspheres. This understanding can then be applied to develop in vitro release tests which better mimic this environment and cause

    BACKGROUND: So-called anti-irritants are added to cosmetic formulations because of their alleged beneficial effect on irritated skin. Documentation for these claims is often limited. However, glycerol has shown anti-irritant properties in experimentally induced irritation from sodium lauryl sulfate...... and nonanoic acid (NON). This study was designed to further substantiate that glycerol added to cosmetic formulations has an anti-irritant effect on experimentally induced skin irritation. OBJECTIVE: We sought to compare glycerol with triamcinolone acetonide as treatments for cutaneous irritation in human....... The treatments (including vehicle and no treatment) were randomized to sites using a Latin square design. The reactions were evaluated clinically and instrumentally. LIMITATIONS: Study was designed to only detect potent anti-irritants. CONCLUSION: Glycerol reduced the irritant effect of both sodium lauryl...

We collected data before and after surgery on intraocular pressure (IOP, anterior chamber (AC cells, best-corrected visual acuity (BCVA, morphologic characteristics of the filtering bleb and complications.Results: The mean time between injection and surgery was 7.8±3.88 days. Postoperative IOP level was significantly lower than preoperative level (31.3±11.44 mmHg at all visits (P<0.02. Antiglaucoma medications were decreased from preoperative (4.9±0.88 to 12-month postoperative (0.8±1.31; P-value <0.001 and also discontinued in seven eyes (70%. About 12 months after surgery, eight eyes (80% with qualified success and two eyes (20% with failed treatment were recorded. AC cells and BCVA did not differ significantly from baseline; however, all inflammations were controlled successfully. Most desirable bleb morphology was shown at 12 months as well. Complications were blepharoptosis and hypotony maculopathy in two eyes (20%.Conclusion: A preoperative PSTA may be an effective and safe option in controlling intraocular inflammation and maintaining bleb function after trabeculectomy in noninfectious uveitic patients with secondary glaucoma during a 12-month period.

    The efficacy of corticosteroid has not been thoroughly studied in the treatment of non-allergic rhinitis. This study was designed to compare the efficacy of nasal corticosteroid in patients with allergic rhinitis (AR), and non-allergic rhinitis (NAR). The efficacy of triamcinolone acetonide nasal spray (TANS) on total nasal symptom scores (TNSS), and nasal peak inspiratory flow rate (nPIFR) was studied in a six-week parallel-group trial of NAR (n: 25), and AR (n: 16) patients. Health-related quality of life (HRQoL) and Epworth Sleepiness Scale (ESS) were also analysed. The TNSSs, and symptom scores of conjunctivitis, snoring, and postnasal drainage were significantly improved in both groups, after two and six weeks of treatment. In contrast to AR, patients with NAR had statistically significant improvement in nasal obstruction, and postnasal drainage beginning from two weeks of the treatment. nPIFR slightly increased in both groups. Scores of generic (SF-36), rhinitis specific (MiniRQLQ) and ESS questionnaires generally improved better in AR than NAR. TANS was well-tolerated in AR and NAR groups with minor adverse events including headache, nasal burning, and bitter mouth taste. Our study disproved the idea of ineffectiveness of corticosteroid treatment in NAR, and showed that triamcinolone acetate may be an alternative drug in the treatment of NAR. Copyright © 2012 SEICAP.

    Full Text Available Lymphangiomas (LMs are uncommon congenital malformations of the lymphatic system, with an estimated incidence of one in 2,000 to 4,000 live births.1 About half of these lesions are diagnosed at birth, and by two years of age, 90% of those with lesions have been diagnosed.2 Histologically, LMs are benign lesions; however, they can pose a serious threat to the patient due to possible growth into surrounding structures, sometimes causing life-threatening complications. Treatment of large head and neck lymphangiomas in young infants is very challenging, due to the risk of surgical complications. Further challenges include the limited volume of blood loss that infants can tolerate, the lack of the option for radiotherapy or radiosurgery, and the high chance of life-threatening complications if the LM is not treated. Here, we report a case of a two-month-old baby girl presenting with a large head and neck lymphangioma. She was successfully treated with intralesional triamcinolone acetonide injections, followed by surgical resection of the lesion.

    Oral lichen planus (OLP) is a common chronic mucocutaneous disease. Patients with atrophic and erosive types of OLP often have symptoms of soreness, and require proper treatment. The main treatment for OLP has been the administration of topical or systemic corticosteroids. The objective of this study was to compare the efficacy of adcortyl cream (triamcinolone acetonide in orabase) with topical pimecrolimus cream for the treatment of erosive OLP. Twenty-eight patients with OLP were enrolled in a single blind clinical trial and assigned to either a pimecrolimus 1% cream group or an adcortyl 0.1% cream group. The medication was applied every day for 2 months and patients were assessed every 2 weeks. The mean lesion size and mean pain and burning sensation scores did not differ between the pimecrolimus and adcortyl cream groups. The pimecrolimus cream was well tolerated. No clinical drug-related adverse events were observed. Topical pimecrolimus cream may be recommended as a safe and effective alternative therapy in the treatment of OLP. Pimecrolimus cream is as effective as adcortyl cream in managing the signs and symptoms of OLP.

    The aim of this present work was to prepare triamcinolone acetonide (TA)-loaded nanostructured lipid carriers (TA-loaded NLCs) for buccal drug delivery systems using the Box-Behnken design. A hot homogenization method was used to prepare the TA-loaded NLCs. Spermaceti (X₁), soybean oil (X₂), and Tween 80 (X₃) were used as solid lipid, liquid lipid, and stabilizer, respectively. The particle size of TA-loaded NLCs was lower than 200 nm and the zeta potential displayed the negative charge in all formulations. The percentage encapsulation efficiency (%EE) of the TA-loaded NLCs showed that it was higher than 80% for all formulations. Field emission scanning electron microscope (FESEM) confirmed that the size of TA-loaded NLCs was approximately 100 nm and energy-dispersive X-ray spectroscopy (EDS) confirmed that the TA could be incorporated in the NLC system. The Higuchi model gave the highest value of the R², indicating that this model was a fit for the TA release profiles of TA-loaded NLCs. Confocal laser scanning microscopy (CLSM) was used to observe the drug penetration within the porcine buccal mucosa and Nile red-loaded NLCs showed significantly higher penetration depth at 8 h than at 2 h. Therefore, TA-loaded NLCs could be an efficient carrier for drug delivery through the buccal mucosa.

    Central giant cell granuloma is a benign condition of the jaws which may present an aggressive behavior. A 9-year-old boy was complaining of swelling in the floor of the mouth. A solid swelling was observed in the area of the lower incisors. From the radiographic exam, we observed a radiolucent image in the mandibular bone with well-defined limits extending from the apical region of tooth 33 to the apical region of tooth 42. Due to the diagnosis and the age of the patient, we chose a conservative treatment, administering subcutaneous injections of calcitonin. During this treatment, no reduction to the lesion was observed. Therefore, we chose to treat the lesion with triamcinolone acetonide. Monthly follow-ups demonstrated good lesion reduction and the absence of any clinical symptoms during the first 2 years. After a 3-year follow-up, the patient returned, presenting mobility of the lower incisors. A significant increase in the size of the lesion was observed. After a biopsy, with the removal of tissue which had the appearance of a cyst capsule, microscopic analyses were found to be compatible with a secondarily infected cyst. Two months following this procedure, the patient did not present tooth mobility anymore and the oral mucosa presented a normal aspect. Following a radiographic exam, full lesion repair was observed. These conservative treatments should be the first option in cases of central giant cell granuloma and the patient must be observed for a long period of time, until no further clinical or radiographic signs of lesions are observed.

    Triamcinolone acetonide (TA) employed for the treatment of atopic dermatitis exhibits limited penetration into the epidermis. This investigation aimed to explore the role of binary solvents in topical drug delivery of TA by developing nanoethosomal glycolic lipid vesicles by infusion method. Screening of vesicles (TA1-TA17) formulated by Box Behnken design identified the optimized formulation (TA10) that was developed as carbomer gels. The gels were then evaluated for pharmaceutical properties and compared with control and reference ethosomal gel (RG). Higher in vitro permeation was found in gels containing TA10, prepared with or without using penetration enhancer (EGP 83.76 ± 0.72% and EG 82.42 ± 0.89%, respectively). CLSM studies depicted deeper uniform penetration of fluorescent tracer into the epidermis via EG as compared with RG and control gel. Enhanced penetration was due to combinational solvent effect exerted by ethanol and propylene glycol. Histological analysis confirmed the non-irritant potential of the gel. Thus, it can be concluded that nanoethosomal glycolic vesicles proved to be an effective non irritant carrier for improvised penetration of triamcinolone acetonide for potential topical therapeutics.

    Intravitreal administration is the method of choice for drug delivery to the posterior segment of the eye with special emphasis on the vitreous body and its surrounding retinal vasculature. In order to gain a better understanding of the underlying distribution processes, an in vitro model simulating the vitreous body (Vitreous Model, VM) and a system simulating the impact of movement on the VM (Eye Movement System, EyeMoS) was previously developed. In the study reported here, these systems were modified in regard to a standardized injection procedure, the diversity of simulated eye movements, extended periods of investigation, the opportunity to simulate the state after vitrectomy and in considering the physiological temperature. Fluorescein sodium (FS) and triamcinolone acetonide (TA) were used as (model) drugs to examine the drug distribution within the VM. Vitrectomy was simulated by replacing half the volume of the polyacrylamide gel that was used as vitreous substitute with the clinically used Siluron® 5000 whereas for a simulated liquefaction half the volume of the gel was replaced by buffer. A simulated liquefaction caused a 12-fold faster distribution of FS compared to the simulated juvenile VM, which was most likely caused by convective forces and mass transfer. Also, the injection technique (injection into the gel or into the buffer compartment) influenced the resulting distribution pattern. Without any liquefaction, the previously described initial injection channel occurred with both (model) drugs and, in the case of TA, remained almost unchanged during the investigation period of 72h. Simulating vitrectomized eyes, TA did not spread uniformly, but either remained in the depot or strongly sedimented within the VM suggesting that a homogenous distribution of a TA suspension is highly unlikely in vitrectomized eyes. High variabilities were observed with ex vivo animal eyes, demonstrating the limited benefit of explanted tissues for such distribution

    Full Text Available Background and aims. Lichen planus is a relatively common mucocutaneous disease, with an unknown etiology. There is no complete cure for oral lichen planus (OLP, but some drugs, including corticosteroids, retinoids, cyclosporine and antibiotics are commonly used for treatment of OLP. The aim of the present study was to compare the effect of combination of triamcinolone and vitamin A mouthwash with triamcinolone mouthwash alone on OLP. Materials and methods. Twenty OLP patients were randomly divided into two groups of 10. The experimental group was treated with combination of triamcinolone and vitamin A mouthwash and the control group was treated with triamcinolone-containing mouthwash alone. The patients were examined once every two weeks and the lesion size, pain and burning sensation were recorded based on visual analogue scale during a two-month period. Data were analyzed by MannWhitney U test using SPSS software. Results. The use of combination of triamcinolone-vitamin A mouthwash was effective in decreasing the pain and burning sensation of OLP (P = 0.012. Decrease in pain and burning sensation were similar in both groups (P = 0.73. The use of combination of triamcinolone-vitamin A mouthwash led to a decrease in the size of keratotic, atrophic and erosive OLP lesions (P = 0. Decrease in the size of the lesions was significantly greater in the study group compared to the control group (P = 0.029. Conclusion. The use of combination of triamcinolone-vitamin A mouthwash is effective in decreasing the size of keratotic, atrophic or erosive lesions.

    The development of an iatrogenic Cushing's syndrome (ICS) followed by secondary adrenal failure remains an exceptional event after a single dose administration of a synthetic glucocorticoid. Medical attention has been drawn recently on the possible impact of ritonavir-based antiretroviral regimens on the systemic deleterious effects of a chronic administration of corticosteroids in HIV-infected patients. Three HIV-infected patients treated by a ritonavir-boosted protease inhibitor (PI) regimen received a single intra-articular injection of 40 mg triamcinolone acetonide in our university hospital. The three patients rapidly developed signs and symptoms of ICS followed by secondary adrenal insufficiency. Special attention must be paid when a single administration of corticosteroids has to be given in HIV-positive patients under ritonavir-boosted antiretroviral treatment, as these patients are at risk of developing early cushingoid features and a prolonged suppression of their hypothalamic-pituitary-adrenal axis.

    A novel and fast simultaneous determination of triamcinolone acetonide (TCA) and salicylic acid (SA) in topical pharmaceutical formulations by sequential injection chromatography (SIC) as an alternative to classical high performance liquid chromatography (HPLC) has been developed. A recently introduced Onyxtrade mark monolithic C18 (50mmx4.6mm, Phenomenex((R))) with 5mm monolithic precolumn were used for the first time for creating sequential injection chromatography system based on a FIAlab((R)) 3000 with a six-port selection valve and 5.0mL syringe pump in study. The mobile phase used was acetonitrile/water (35:65, v/v), pH 3.3 adjusted with acetic acid at flow rate 0.9mLmin(-1). UV detection provided by fibre-optic DAD detector was set up at 240nm. Propylparaben was chosen as suitable internal standard (IS). There is only simple pre-adjustment of the sample of topical solution (dilution with mobile phase) so the analysis is not uselessly elongated. Parameters of the method showed good linearity in wide range, correlation coefficient >0.999; system precision (relative standard deviation, R.S.D.) in the range 0.45-1.95% at three different concentration levels, detection limits (3sigma) 1.00mugmL(-1) (salicylic acid), 0.66mugmL(-1) (triamcinolone acetonide) and 0.33mugmL(-1) (propylparaben) and recovery from the pharmaceutical preparations in the range 97.50-98.94%. The chromatographic resolution between peaks of compounds was more than 4.5 and analysis time was 5.1min under the optimal conditions. The advantages of sequential injection chromatography against classical HPLC are discussed and showing that SIC can be a method of option in many cases.

    Full Text Available PURPOSE: To evaluate the effect of preoperative intravitreal bevacizumab (IVB or triamcinolone (IVT on the rate of early postvitrectomy hemorrhage in proliferative diabetic retinopathy (PDR. METHODS: Eligible eyes were assigned randomly to 1 of 3 groups: the IVB group received 1.25 mg bevacizumab, the IVT group received 4,0mg triamcinolone and the control group underwent a sham procedure. The primary outcome measure was the incidence of early postvitrectomy hemorrhage. Secondary outcome measures included changes in visual acuity (BCVA and adverse events. RESULTS: Twenty and seven eyes, 9 in each group were randomized. The incidence of vitreous hemorrhage was lower in the IVB group (p=0.18. Postoperative vitreous hemorrhage at 1 month also was less in the IVB group compared with the control group (p > 0.05. The rate of bleeding immediately after surgery was higher in IVT group with 4 (44.4% cases. The overall mean visual acuity was 1.72 ± 0.37 logMAR preoperatively and 1.32 ± 0.73 logMAR in 6 months after surgery. Accessing visual acuity by group evidenced that the IVB group had initial mean logMAR VA of 1.87 and 1.57 logMAR VA at the six months (p = 0.84. In IVT group, initial mean VA was 1.75 logMAR and 0.96 logMAR VA at six months (p < 0.001. And in control group, the initial mean VA was 1.85 logMAR and 1.57 logMAR VA at six months (p= 0.34. CONCLUSION: Intravitreal injection of bevacizumab 1 week before vitrectomy seems to reduce the incidence of early postvitrectomy hemorrhage in diabetic patients. There was a better visual acuity outcome in the triamcinolone group.

    To compare the effects of intravitreal injection of bevacizumab (IVB) with intravitreal triamcinolone acetonide (IVTA) on the treatment of cystoid macular edema (CME) secondary to retinal vein occlusion (RVO). A literature search was conducted using PubMed, the Cochrane Central Register of Controlled Trials, Web of Science and the Chinese Biomedical Database. The comparison was divided into two groups, group 1 conducted comparison in branch RVO (BRVO) or central RVO (CRVO), group 2 conducted comparison in ischemic-RVO or nonischemic-RVO. Pooled mean differences (MDs) for changes in visual acuity (VA), central macular thickness (CMT) and intraocular pressure (IOP) were calculated in groups at 4, 12 and 24wk after treatment respectively. Eight studies comparing the efficacy of IVB with IVTA were included in the Meta-analysis. In group 1, in BRVO, significant difference was shown on the comparison of CMT at 24wk (MD, -45.66; 95% CI, -76.03 to -15.28; P=0.003), IVB was effective on BRVO for at least 24wk; no significant differences were found in the comparison of VA at each time points (P>0.05 respectively). In CRVO, no significant differences were found in the comparison of VA or CMT between IVB and IVTA at each time points (P>0.05, respectively). In group 2, in ischemic-RVO, significant differences were shown in the comparison of VA (MD, -0.28; 95% CI, -0.42 to -0.14; Pcomparison of VA or CMT between IVB and IVTA at each time points (P>0.05, respectively). The occurrence of high IOP was much lower in IVB group. This Meta-analysis suggested that IVB was effective in decreasing CMT in BRVO for at least 24wk, IVB is more effective on improving VA and reducing CMT in ischemic-RVO. IVB is more promising on RVO than IVTA.

    Background Ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) with intrabursal steroid injection is an elective treatment for painful rotator cuff calcific tendinopathy. Purpose To compare the efficacy of post-US-PICT intrabursal 40 mg injection of triamcinolone acetonide (TA) versus methylprednisolone acetate (MA). Material and Methods Forty patients (22 women; mean age 48.7 ± 7.2 years) with painful shoulder calcific tendinopathy, treated with TA or MA injected intrabursally after US-PICT, were included in this randomized controlled trial. At baseline and after 1, 7, 15, 30, 45, and 180 days, patients underwent US and clinical examination, using Constant (CS) and VAS (VS) scores. Complications and analgesic use were also recorded. Results Compared to baseline, at the 45-day follow-up, TA and MA group showed a similar improvement (Δ) in CS (42 ± 10 versus 36 ± 9 points) and VS (-4.4 ± 1.3 versus -3.6 ± 1.3 points). At the 180-day follow-up, the improvement was higher in TA versus MA (ΔCS: 53 ± 7 versus 44 ± 7 points; ΔVS: -4.9 ± 1.1 versus -3.9 ± 1 points). Multivariate analysis showed a mean CS higher ( P = 0.02) in TA versus MA group, while VS was similar. TA had a 5 × higher ( P = 0.007) chance of reaching complete remission (CS = 100 points) than MA group. A progressive decrease in analgesic use, concomitant to a significant and similar reduction of bursitis and calcifications, was observed in both groups. No major complications occurred. Conclusion Two-needle US-PICT with intrabursal steroid injection is safe and effective. The chance of reaching better scores and, even more important for a clinical perspective, of functional recovery, is higher in patients treated with TA than MA.

    The aim of the study was to formulate a microemulsion (ME) using chitosan (CH) and the butter oil (BO) as a permeation enhancer for targeting drug to the posterior segment of the eye, via topical route. Triamcinolone acetonide (TA) was selected as the model drug since it undergoes extensive first-pass metabolism, leading to poor oral bioavailability of 23%. For optimisation of BO concentration, different ratios of TA:BO were prepared by simple physical mixing in the ratio of 1:9 to 9:1 and diffusion study was performed. MEs containing TA, TA:BO and TA CH ME were formulated by water titration method. Globule sizes of TA ME, TA:BO ME and TA CH ME were found to be 66.06 ± 0.32 nm, 78.52 ± 1.50 nm and 97.30 ± 2.50 nm, respectively. In ex vivo diffusion studies using goats eye, TA:BO ME (31.33 ± 0.46 and 33.98 ± 0.23) and TA CH ME (24.10 ± 0.41 and 27.00 ± 0.18) showed higher percentage of drug diffusion in comparison to TA ME (13.29 ± 0.41and 15.56 ± 0.34) and TA solution (8.20 ± 1.04 and 10.39 ± 0.22) in presence and in absence of vitreous humour. Fluorescence intensity of coumarin-6 (as a marker) loaded ME with BO and CH was found to be higher, confirming their role in altering membrane permeability and facilitating coumarin-6 diffusion to the posterior chamber. Overall, it was concluded that BO enhances the bioavailability of TA across the retina, thereby proving its potential as permeation enhancer in facilitating drug delivery to the posterior segment of the eye.

    Intra-articular (IA) corticosteroids relieve osteoarthritis (OA) pain, but rapid absorption into systemic circulation may limit efficacy and produce untoward effects. We compared the pharmacokinetics (PK) of IA triamcinolone acetonide (TA) delivered as an extended-release, microsphere-based formulation (FX006) vs a crystalline suspension (TAcs) in knee OA patients. This Phase 2 open-label study sequentially enrolled 81 patients who received a single IA injection of FX006 (5 mL, 32 mg delivered dose, N = 63) or TAcs (1 mL, 40 mg, N = 18). Synovial fluid (SF) aspiration was attempted in each patient at baseline and one post-IA-injection visit (FX006: Week 1, Week 6, Week 12, Week 16 or Week 20; TAcs: Week 6). Blood was collected at baseline and multiple post-injection times. TA concentrations (validated LC-MS/MS, geometric means (GMs)), PK (non-compartmental analysis models), and adverse events (AEs) were assessed. SF TA concentrations following FX006 were quantifiable through Week 12 (pg/mL: 231,328.9 at Week 1; 3590.0 at Week 6; 290.6 at Week 12); post-TAcs, only two of eight patients had quantifiable SF TA at Week 6 (7.7 pg/mL). Following FX006, plasma TA gradually increased to peak (836.4 pg/mL) over 24 h and slowly declined to IA injection prolonged SF joint residency, diminished peak plasma levels, and thus reduced systemic TA exposure relative to TAcs.

    Full Text Available Background Tight control of severe rheumatoid arthritis (RA in patients with high disease activity, even when using biologics, is sometimes difficult using a treat-to-target strategy. Switching from one biologic to another is associated with lower efficacy than that in treatment-naive cases. We developed the K-method that involves simultaneous treatment with golimumab and intra-articular joint injection of triamcinolone acetonide (TA in patients undergoing switching of biologics. We performed this retrospective case–control study to investigate the efficacy of achieving an immediate treatment response using the K-method. Methods This study involved 20 patients with RA (control group, 10 patients; K-method group, 10 patients. Patients in the control group were switched to golimumab from other biologics without intra-articular injection of TA. The K-method involved injection of 1 mL of TA (40 mg/mL and 2 mL of 1% lidocaine hydrochloride into swollen or painful joints on the same day as golimumab treatment. A quick response one day after treatment was compared between the two groups according to the disease activity score 28 based on C-reactive protein (DAS28 CRP, clinical disease activity index (CDAI, simplified disease activity index (SDAI, European League Against Rheumatism (EULAR response, and remission rate. These parameters were investigated for 24 weeks. Results The K-method group showed significant improvements in DAS28 CRP, CDAI, and SDAI at one day, 12 weeks, and 24 weeks compared with the control group. The number of swollen and tender joints and the patient and doctor global visual analog scale scores were also significantly different between the two groups. The remission rates based on DAS28 CRP were 30% at one day, 50% at 12 weeks, and 60% at 24 weeks in the K-method group. The EULAR good/moderate response rates were 80% at one day, 90% at 12 weeks, and 90% at 24 weeks in the K-method group; however, these rates were only 10%, 40

    Objective: To compare the use of intralesional triamcinolone acetonide and its combination with 5 flourouracil in the treatment of keloid and hypertrophic scars in terms of reduction in initial height of the scar. Methods: The randomised controlled trial was conducted at the Department of Plastic Surgery, King Edward Medical University, Lahore, from March 2011 to December 2012. It comprised patients of both genders having keloids or hypertrophic scars (1 cm to 5 cm in size) having no history of treatment for the scars in preceding 6 months. Those who were pregnant, planning pregnancy or lactating were excluded. The subjects were divided into two groups: Group A received intralesional triamcinolone acetonide alone; and Group B received triamcinolone acetonide + 5 flourouracil. Eight injections were given at weekly interval. Scars were assessed 4 weeks after the completion of treatment on a five-point scale. SPSS 16 was used for statistical analysis. Results: The 150 subjects in the study were divided into two equal groups of 75(50%) each. Good to excellent results were seen in 51(68%) cases in Group A compared to 63(84%) in Group B. Frequency of complications was 18(24%) and 6(8%) in Group A and Group B respectively. Conclusion: Combination of triamcinolone acetonide and 5 flourouracil is superior to triamcinolone acetonide therapy in the treatment of keloids and hypertrophic scars. (author)

    Full Text Available Background. Cervical interlaminar epidural steroid injections (ESIs are commonly performed procedures to treat painful cervical radiculopathy, but little is known about the systemic absorption and serum levels of steroids following injection. The primary objective of this study was to investigate the pharmacokinetics of fluoroscopy-guided cervical epidural-administered triamcinolone acetonide in a cohort of patients with cervical radicular pain seeking treatment in a pain medicine clinic. Methods. The study cohort included eight patients undergoing a fluoroscopically guided C7-T1 interlaminar ESI at a pain medicine specialty clinic. Blood was collected prior to the ESI and on days 1, 2, 4, 6, 8, 14, 21, 28, 35, and 42 following the injection. The sample extract was analyzed by tandem mass spectrometry. Results. The terminal elimination half-life of cervical epidural-administered triamcinolone in a noncompartmental analysis was 219 hours. In the noncompartmental analysis, peak triamcinolone concentrations of 5.4 ng/mL were detected within 22.1 hours after administration. Conclusions. The pharmacokinetics of cervical epidural-administered triamcinolone is consistent with our previous study of lumbar ESI, demonstrating that the elimination half-life is longer than that which has been reported following intravenous triamcinolone. The elimination half-life was shorter following cervical ESI than that which has been reported following lumbar ESI.

    Full Text Available We report two cases of fulminant toxoplasmic retinochoroiditis following intravitreal triamcinolone acetonide (IVTA administration. Case 1: A 42-year-old female received IVTA for presumed non-infectious panuveitis. Within 2 months, she developed diffuse macular retinochoroiditis with optic disc edema. Upon starting anti-toxoplasmic therapy (ATT, her intraocular inflammation resolved with catastrophic damage to the disc and macula. Case 2: A 30-year-old male received IVTA for presumed reactivation of previously scarred toxoplasmic retinochoroiditis. Despite simultaneous ATT, within 6 weeks, he developed extensive, multifocal macular retinochoroiditis. He continued to require ATT for 18 months and later underwent vitrectomy with silicone oil placement for severe epiretinal proliferation. Aqueous tap polymerase chain reactions were found positive for Toxoplasma gondii in both cases. In conclusion, IVTA administration can lead to fulminant toxoplasmic retinochoroiditis even when used with appropriate ATT. Extreme caution should be exercised while administering depot corticosteroids in eyes with panuveitis of unknown origin.

    AIM: To evaluate the efficacy of intravitreal triamcinolone (IVTA) for the treatment of diffuse diabetic macular oedema (DME) refractory to conventional argon macular laser therapy. METHODS: A prospective, consecutive, and noncomparative case series was undertaken involving 38 eyes of 38 patients with refractory DME. Triamcinolone acetonide (4 mg) in 0.1 ml was injected intravitreally. LogMar visual acuity (VA) and macular thickness measured by ocular coherence tomography (OCT) were assessed preoperatively and postoperatively at 1, 3, and 6 months. RESULTS: All patients completed 6 months of follow up. VA (mean+\\/-SD) improved from 0.905+\\/-0.23 to 0.605+\\/-0.28, 0.555+\\/-0.29, and 0.730+\\/-0.30 at 1, 3, and 6 months, respectively. Macular thickness baseline (mean+\\/-SD) on OCT was 418.7+\\/-104.2 microm and this decreased to 276.9+\\/-72.6 microm, 250.6+\\/-53.1 microm, and 308.8+\\/-87.3 microm at 1, 3, and 6 months, respectively. CONCLUSIONS: IVTA may be a potential temporary treatment for refractory DME. It is effective in decreasing macular thickness and improving VA but the effect lasts approximately for 6 months in the majority of patients. Further investigations are required to establish the safety of IVTA for the treatment of DME.

    Full Text Available Background: Alopecia areata (AA is a chronic non-scarring alopecia that involves the scalp and/or body, and is characterized by patchy areas of hair loss without any signs of clinical inflammation. Various therapies have been proposed for their treatment.But none have been shown to alter the course of the disease. Platelet Rich Plasma (PRP is a volume of autologous plasma that has a high platelet concentration. Growth factors released from platelets may act on stem cells in the bulge area of the follicles, stimulating the development of new follicles and promoting neovascularization. Aim: To evaluate and compare the efficacy of intralesional injection of autologous platelet rich plasma with intralesional injection of triamcinolone acetonide (10mg/ml in the treatment of alopecia areata. Methodology: 74 patients with alopecia areata were allocated into 2 groups and treated with triamcinolone and PRP injections. Treatment outcome was measured by taking into account extent and density of regrowth of hair and was expressed as a percentage of overall growth. Results: Forty eight patients were treated with triamcinolone injections and 26 patients were treated with PRP injections. Patients treated with PRP had an earlier response at the end of 6weeks than patients treated with triamcinolone. However, this difference was statistically insignificant. The overall improvement at the end of 9 weeks was 100% for all patients in both groups. Conclusion: PRP is a safe, simple, biocompatible and effective procedure for the treatment of alopecia areata with efficacy comparable with triamcinolone.

    Full Text Available Steven M Couch, Sophie J BakriMayo Clinic Department of Ophthalmology, Mayo Clinic, Rochester, MN, USAAbstract: Triamcinolone acetonide (TA is a corticosteroid that has many uses in the treatment of ocular diseases because of its potent anti-inflammatory and anti-permeability actions. Intraocular inflammation broadly referred to as uveitis can result from several causes, including the immune system and after ophthalmic surgery. One of the most common reasons for vision loss with uveitis is macular edema. TA has been used for many years as an intravitreal injection for the treatment of ocular diseases. Several case control studies have been reported showing the efficacy of TA in the treatment of intraocular inflammation and associated macular edema caused by Behcet’s disease, Vogt-Koyanagi-Harada syndrome, sympathetic ophthalmia and white dot syndromes. It has also been shown efficacious in cases of pars planitis and idiopathic posterior uveitis. Some authors have reported its use in postoperative cystoid macular edema. Many of the studies on the use of TA in controlling intraocular inflammation and concomitant macular edema showed its effect to be transient in many patients requiring reinjection. Complications can arise from intravitreal injection of TA including elevated intraocular pressure and cataract. Rarely, it can be associated with infectious and non-infectious endophthalmitis. TA may be useful as an adjuvant in the treatment of uveitis and its associated macular edema, especially in patients resistant or intolerant to standard treatment.Keywords: triamcinolone acetonide, Behcet’s disease, sympathetic ophthalmia, Vogt-Koyanagi-Harada syndrome, white dot syndromes, uveitis, cataract surgery, macular edema, endophthalmitis

    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

    To compare the flow rate through different gauge needles of triamcinolone acetonide with benzyl alcohol (TABA) versus preservative-free triamcinolone acetonide injectable suspension (TAIS). Experimental injections of 1 mL of TABA or TAIS were performed through a 27-, 30-, or 32-gauge needle. A piezoelectric pressure transducer connected to a personal computer was placed between the syringe and needle to record the force-time relationship and assess the flow rate (mL/s). Measurements were performed in triplicate. Flow rates were similar between preparations using a 27-gauge needle. Using a 30-gauge needle, the flow rate was 0.058 mL/s for TABA and 0.178 mL/s for TAIS. Using a 32-gauge needle, no flow was sustained by TABA, whereas the flow rate of TAIS was 0.114 mL/s (P gauge needle without the risk of obstruction. Occlusions were seen with TABA using the 30- and 32-gauge needles. Copyright 2014, SLACK Incorporated.

    To determine the triamcinolone concentration in the aqueous humor after anterior sub-Tenon injection versus posterior sub-Tenon injection and the possible association between the levels of triamcinolone in the aqueous and the elevation in intraocular pressure (IOP). University teaching hospitals at Wenzhou and Shanghai, China. Prospective case series. The aqueous humor was sampled and triamcinolone quantitated after anterior sub-Tenon injection or posterior sub-Tenon injection in a cohort of patients and in experimental rabbits. Patients' IOPs were measured before and up to 3 months after triamcinolone acetonide injection. The study comprised 46 patients and 18 rabbits. The mean aqueous humor triamcinolone concentration in rabbit eyes and human eyes was significantly higher after an anterior sub-Tenon injection than that after a posterior sub-Tenon injection (rabbit eye: anterior sub-Tenon injection, 2.67 ng/mL ± 0.78 [SD] and posterior sub-Tenon injection 1.38 ± 0.48 ng/mL; human eye: 133.8 ± 149.2 ng/mL and 10.2 ± 10.9 ng/mL, respectively) (both P humor was significantly higher in human eyes than in rabbit eyes (133.8 ± 149.2 ng/mL versus 11.0 ± 8.1 ng/mL) (P = .0003). The levels of triamcinolone in the human aqueous humor had a significant positive association with the elevation in IOP (β = 0.12, P = .026). The triamcinolone level in aqueous humor was associated with IOP elevation after sub-Tenon application. Posterior sub-Tenon injection with a small injection volume of concentrated suspension offered a better targeted delivery and might significantly reduce steroid-associated IOP elevation.

    Intranasal antihistamine has not been thoroughly studied in the treatment of rhinitis of different etiologies. This study was designed to show the comparative efficacy of nasal antihistamine and nasal corticosteroid in patients with allergic rhinitis (AR) and nonallergic rhinitis (NAR). A comparison of the efficacy of azelastine nasal spray (AZENS) versus triamcinolone acetonide nasal spray (TANS) on total nasal symptom scores (TNSS), nasal peak inspiratory flow rate (nPIFR), and nasal cytology was studied in a 2-week randomized parallel-group trial. The Epworth Sleepiness Scale (ESS) and health-related quality of life (HRQoL) were also analyzed. The study group consisted of 132 patients (100 women and 32 men) with a mean age of 33.14 +/- 12.52 years. Sixty-nine patients had AR and 63 had NAR. Although TNSS including sneezing, itching, rhinorrhea, congestion-but not anosmia-significantly improved in both groups, intranasal azelastine reduced ocular symptoms greatly compared with intranasal triamcinolone (p = 0.05). Patients with NAR seemed to respond more to TANS, whereas AZENS was more useful in AR. The nPIFR improved in AR and NAR, with no significant difference between the treatment groups. Neither intranasal azelastine nor intranasal triamcinolone changed cytology in nasal lavage. Both medications were well tolerated, but AZENS led to more adverse events than TANS (56.9 and 19%, respectively; p = 0.001), mainly because of bitter taste. Scores on each domain of generic HRQoL (36-Item Short-Form Health Survey) and mini-rhinitis QoL questionnaires, as well as ESS score, significantly improved in both groups, irrespective of rhinitis etiology. In this first comparative demonstration, AZENS appears to be as effective as triamcinolone in symptom scores, nPIFR, ESS, and HRQoL, equally in AR and NAR.

  2. [Kounis syndrome: a paradoxal non-ST elevation myocardial infarction case after triamcinolone treatment for dermatitis].

    2018-04-01

    Kounis syndrome is defined as the clinical development of acute coronary syndrome caused by the activation of inflammatory cells due to an allergy, hypersensitivity, anaphylaxis, or anaphylactic reaction. Corticosteroids that are used in the treatment of many inflammatory conditions may paradoxically cause allergic reactions and even anaphylaxis. This article is a description of the case of a 52-yearold female patient who had a non-ST elevation myocardial infarction after the administration of triamcinolone that was relieved with antihistaminic treatment. The patient had been diagnosed with dermatitis at another medical center and injected with 40 mg/mL (intravenous [IV]) of triamcinolone acetonide and developed chest pain 15 minutes after the first dose. Despite a normal physical examination and echocardiogram, laboratory tests revealed troponin positivity and an inferolateral ST depression was present on an electrocardiogram (ECG). The ECG findings and clinical symptoms resolved completely after conservative anti-ischemic treatment and antihistaminic therapy (pheniramine maleate 45.5 mg/2 mL, Avil ampoule, IV; Sanofi-Aventis, Paris, France) and coronary angiography evaluation of the arteries was normal. The heart, and in particular the coronary arteries, are among the organs that are most damaged during hypersensitivity reactions and anaphylaxis. Although Kounis syndrome is not a rare condition, few cases have been reported in clinical practice. The failure to recognize Kounis syndrome due to inadequately defined cases may lead to unwanted medical results. Kounis syndrome should be kept in mind in order to make a rapid and accurate diagnosis.

    Endoscopic submucosal dissection (ESD) of large gastric lesions often leads to severe gastric strictures, especially in cases of large ESD in the antrum of the stomach. It has recently been reported that balloon dilation, mucosal incision, and local steroid injections can successfully treat gastric strictures. However, there are some complications with existing methods and decreasing the quality of life. We have developed a novel method to prevent severe gastric strictures that does not involve balloon dilation, mucosal incision, or steroid injections after circumferential ESD. Our original method involves the submucosal injection of a mixed solution composed of triamcinolone acetonide and a general solution of glycerol, hyaluronic acid, and a small amount of indigo carmine and epinephrine during the ESD procedure; this mixture is called a mixed solution of triamcinolone (MST). According to standard ESD procedures, several milliliters of MST are injected into the submucosal layer for the purpose of elevating the submucosa during ESD resulting in prevention of severe strictures. Our method using MST take several advantages such as MST method suppress inflammation in ulcer from initial phase, prevention of stricture without obstructive symptoms, and does not require several ballooning. Therefore, MST method is safe and gentle, shorten the hospitalization duration. Here, we described two cases in which we prevented severe strictures of the gastric antrum after completing a circumferential ESD using MST without any complications.

    To investigate whether intravitreal Kenalog (IVTK; Bristol Meyers Squibb Company, Princeton, NJ) produces histologic or electroretinographic changes in the rabbit retina up to 3 months after injection. Ten Dutch-belted rabbits were injected with 4 mg/0.1 mL Kenalog in one eye and 0.1 mL physiologic salt solution (PSS) in the fellow eye. Simultaneous bilateral dark-adapted electroretinography was performed 2 weeks and 12 weeks after injection in 10 and 6 rabbits, respectively. Saturated a-wave amplitude, maximal scotopic b-wave amplitude, and individual a-wave and b-wave amplitudes of IVTK-injected and control eyes were compared at 2 and 12 weeks after injection. Light microscopy was performed on both eyes of three animals 3 months after injection. Immunohistochemistry was performed with antibodies recognizing vimentin and human alveolar macrophage (HAM)-56, markers of glial cells and macrophages, respectively. No significant difference was observed in the saturated a-wave or maximal scotopic b-wave amplitudes between the PSS-injected eyes and the IVTK-injected eyes at 2 weeks (P = 0.95 and P = 0.56, respectively) and 12 weeks (P = 0.82 and P = 0.17) after injection. Light microscopy and immunohistochemistry disclosed only rare macrophages in the vitreous of IVTK-injected eyes. Retinal layers, retinal pigment epithelium, and choriocapillaris in treatment and control eyes were unremarkable. No demonstrable electroretinographic or histologic changes occurred to suggest immediate or delayed widespread retinal toxicity of IVTK.

    Aim: To evaluate the efficacy of periocular triamcinolone acetonide for the treatment of thyroid associated ophthalmopathy (TAO), and the presence of ocular or systemic adverse effects. Methods: A multicentre prospective pilot study was performed on patients diagnosed with Graves’ ophthalmopathy less than 6 months before entry to the study. Patients were admitted to the study and were randomised into two groups: treatment and control. The treatment group received four doses of 20 mg of triamcinolone acetate 40 mg/ml in a peribulbar injection to the inferolateral orbital quadrant. Both groups were evaluated by measuring the area of binocular vision without diplopia on a Goldmann perimeter and the size of the extraocular muscles on computed tomography (CT) scans. Ophthalmological and systemic examinations were done to rule out ocular and systemic adverse effects. Follow up was 6 months for both groups. Results: 50 patients were eligible for the study. 41 patients completed the study. There was an increase in the area of binocular vision without diplopia in the treatment group (Σ initial: mean 231.1 (SD 99.9) and final absolute change, mean 107.1 (SD 129.0)) compared to the control group (Σ initial: mean 350.7 (SD 86.5) and final absolute change, mean −4.5 (SD 67.6)). The sizes of the extraocular muscles were reduced in the treatment group (mean (inferior rectus initial values): 1.3 (0.7), final percentage change: −13.2 (25.7), medial rectus initial values: 1.2 (0.6), final percentage change: −8.2 (20.7), superior rectus-levator palpebrae initial values: 1.2 (0.6), final percentage change: −9.5 (29.1), lateral rectus initial values: 1.0 (0.4), final percentage change: −11.5 (20.6)) compared to the control group (inferior rectus initial values: 0.9 (0.3), final percentage change: −4.0 (21.5), medial rectus initial values: 0.9 (0.3), final percentage change: 0.6 (22.4), superior rectus-levator palpebrae initial values: 0.9 (0.3), final percentage change

    Multiple sclerosis (MS) is an autoimmune disease affecting young people and is a major cause of disability. In the course of time, disability progresses and symptoms like spasticity may occur. Spasticity is a major cost factor in MS patients. Various agents are approved for the treatment of spasticity, but each of those agents may have several side effects. Intrathecally administered steroids (triamcinolone-acetonide (TCA)) may be efficient in treating spasticity in patients with lesions in the spinal cord and no response to first-line therapeutics. The aim of this study is to show effects of TCA treatment on clinical parameters in patients with MS. This multicentre open label study included 54 patients with MS. The clinical outcome parameters were spasticity, disability, maximum walking distance, bladder function and quality of life. All patients received physiotherapy in addition to TCA treatment to obtain optimal effects on clinical parameters. Spasticity, maximum walking distance as well as disability improved significantly (P ⩽ 0.001) during TCA applications. Bladder function improved in every seventh patient. We observed the effects of intrathecally administered TCA on different clinical parameters including bladder function. TCA administration is a safe method to treat different symptoms in MS patients. Longitudinal trials with repeated TCA cycles are needed to show long-term effects. Besides TCA treatment, physiotherapy contributes to the improvement of clinical parameters.

    There is little evidence about the comparative efficacy of corticosteroids in the treatment of painful shoulder. The main aim was to compare the efficacy of methylprednisolone (MTP) versus triamcinolone (TMC) in the treatment of painful shoulder using an ultrasound-guided injection. Patients with painful shoulder due to subacromial bursitis and partial or full-thickness rotator cuff tears demonstrated by musculoskeletal ultrasound received a guided-injection of MTP acetate 40 mg (12 patients) or TMC acetonide 40 mg (12 patients). Range of motion and pain visual analogue scale were registered at 10 and 30 min, 1 and 2 weeks postinjection. Two weeks postinjection, both groups reported a mean improvement in range of motion (33%) and relief of pain (61%). Relief of pain of 50% or more was observed in 92% of patients in MTP group and 50% of TMC group (p = 0.02). Two months postinjection, 50% of the patients in MTP group and 25% in TMC group reported total relief of pain (p = 0.3). Patients with painful shoulder receiving an ultrasound-guided injection of MTP or TMC have a rapid and sustained overall response. Relief of pain tends to be more rapid with MTP than TMC.

This study aimed to assess the effectiveness of combined transpupillary thermotherapy (TTT with subtenon triamcinolone acetonide (TA injection in treatment of choroidal neovascularization (CNV in patients with ARMD. Materials & Methods: In this clinical trial, 63 eyes of 57 patients with CNV secondary to exudative age-related macular degeneration (ARMD were studied. All CNVs (including 20 predominantly classic and 43 predominantly occult lesions were treated with diode laser (810nm. In 20 eyes with predominantly classic CNVs, 20 mg and 40 mg subtenon triamcinolone was injected in 12 and 8 eyes respectively. The patients were followed for a mean of 9.1 months (ranging from 5.5 to 16 months. The average number of treatment sessions was 1.25. In 43 eyes with occult CNV, 20 mg and 40 mg subtenon triamcinolone was injected in 31 eyes and in 12 eyes respectively. Mean follow up time was 12 months (4.5 to 23 months. Mean treatment times was 1.17. A variable spot size of 0.8, 1.2, 2 and 3 mm was used depending on the size of CNV and treatment was given in one area for 1 minute. Thermotherapy was adminstered through a contact lens at a power range between 120-560 mw. At the end of treatment, each patient randomly received 20 mg or 40 mg subtenon triamcinolone acetonide injection in superotemporal quadrant. Outcome was assessed with clinical and angiographic examination.collected data were analyzed by one-sample and paired –sample T test, using SPSS software. Results: At the end of the study in first group, visual acuity remained stable (0 to ± one line in 14 out of 20 (70 % of eyes, improved (> one line in 2 of 20 (10 % eyes and showed a

    The aim of the study was to compare the length of treatment and efficiency of applied therapy in two groups of patients with chalazion who underwent surgical procedure or got triamcinolone application in chalazion. Our study included 30 patients with chalazions that persisted for about one month. All of them were resistant to applied topical antimicrobial therapy. These patients were devided in two groups. 15 patients underwent surgical procedure that included incision, excochleation and excision of the capsule of chalazion, while other 15 patients underwent triamcinolone aplication directly in chalazion (dosage of 2-4 mg). Patients were followed up a day after therapy, two weeks after therapy and one month after applied therapy. We found that chalazion treatment with triamcinolone application directly in the lesion was to be more comfortable for patients, took less time to treat and needed no additional topical antimicrobial therapy.

    João Márcio Prazeres dos Santos

    Full Text Available OBJECTIVE:to assess the effects of injectable triamcinolone on keloid scars length, height and thickness, and on the number of cells undergoing apoptosis.METHODS:This study consists in a prospective, controlled, randomized, single-blinded clinical trial, conducted with fifteen patients with ear keloids divided into two groups: group 1 - seven patients undergoing keloid excisions, and group 2 - eight patients undergoing keloid excisions after three sessions of infiltration with one ml of Triamcinolone hexacetonide (20mg/ml with three week intervals between them and between the last session and surgery. The two groups were homogeneous regarding age, gender and evolution of the keloid scar. The keloid scars of patients in group 2 were measured for the length, height and thickness before triamcinolone injection and before surgery. A blinded observer performed morphological detailing and quantification of cells in hematoxylin-eosin-stained surgical specimens. An apoptotic index was created.RESULTS: The apoptotic index in group 1 was 56.82, and in group 2, 68.55, showing no significant difference as for apoptosis (p=0.0971. The reduction in keloid dimensions in Group 2 was 10.12% in length (p=0.6598, 11.94% in height (p=0.4981 and 15.62% in thickness (p=0.4027.CONCLUSION:This study concluded that the infiltration of triamcinolone in keloid scars did not increase the number of apoptosit and did not reduce keloids' size, length, height or thickness.

    Full Text Available Background: We report a case of reversal of an acute corneal graft rejection following multiquadrant subtenon triamcinolone injection. Case Presentation: A 19-year-old woman who had acute corneal graft rejection failed to show resolution of the graft rejection after standard treatment with systemic, intravenous, and topical steroids. The graft rejection, however, responded to injection of triamcinolone in multiple subtenon quadrants. Conclusions: For corneal graft rejection, multiquadrant subtenon triamcinolone injections may be a safe adjunct to systemic treatment.

    Full Text Available The purpose of this report is to evaluate the efficacy and safety of combined intravitreal injection of bevacizumab and intravitreal triamcinolone acetonide (IVTA for recurrent inflammatory choroidal neovascular membrane (CNVM. It was a prospective interventional study of a young female, who was a known case of Vogt-Koyanagi-Harada syndrome. She presented with an inflammatory choroidal neovascualar membrane and signs of panuveitis in the right eye. She underwent a complete ophthalmic examination. She was given intravitreal injection of bevacizumab and IVTA at different sites. There was complete regression of CNVM and ocular inflammation within a week. After six months, she had recurrence of CNVM in the same eye, which was treated similarly. There was a complete resolution of CNVM and ocular inflammation after the combination therapy and systemic steroids, until one year of follow-up. No serious systemic or ocular adverse events were noted. Combination therapy appears to be an effective and safe method in the management of recurrent inflammatory CNVM.

    Cushing's syndrome is a collection of signs and symptoms due to hypercortisolism. Prolong use of topical steroid may cause this syndrome and suppression of hypothalamic and pituitary function, however such events are more common with oral and parenteral route. There are very few cases of Cushing's syndrome with a topical application amongst which triamcinolone is the rarest drug. We report a case of 11-year-old boy is presented who developed Cushing's disease by topical application. The child had body rashes for which the caregiver consulted a local quack, a topical cream of triamcinolone was prescribed. After application for three months, the patient became obese and developed a moon-like face. A thorough biochemical workup and diagnostic test for Cushing's disease was done to confirm. The following case report a dramatic example of development of the syndrome from chronic topical application of the least potent corticosteroid.

    Full Text Available Christos Haritoglou, Aljoscha S Neubauer, Marcus KerntDepartment of Ophthalmology, Ludwig-Maximilians-University, Munich, GermanyAbstract: Diabetic macular edema (DME is a potentially sight-threatening disease that predominantly affects patients with type 2 diabetes. The pathogenesis is complex, with many contributing factors involved. In addition to overexpression of vascular endothelial growth factor in the diabetic eye, there is an inflammatory pathway that contributes to the breakdown of the blood-retina barrier and nonperfusion. In addition to vascular endothelial growth factor inhibitors, clinical and experimental investigations underline the great potential of steroids in the treatment of DME. Fluocinolone acetonide is currently the only corticosteroid approved for the treatment of DME in Europe. It is manufactured as an intravitreal insert, releasing fluocinolone acetonide at a rate of 0.2 µg per day. Phase III clinical studies have demonstrated that the beneficial effect of the fluocinolone acetonide insert lasts up to 3 years. Improvement in visual acuity was especially remarkable in patients with a prolonged duration of DME of at least 3 years at the initiation of therapy. Cataract formation occurs in nearly all phakic eyes treated, and needs to be considered when the indication for treatment is made. Given the efficacy versus potential complications of the insert, fluocinolone acetonide represents a promising second-line treatment option in patients with DME. Fluocinolone appears to be especially beneficial for patients whose options for visual recovery have seemed limited up until now.Keywords: diabetic macular edema, fluocinolone acetonide

    To describe a case of iatrogenic Cushing's syndrome (ICS) following a triamcinolone injection for subscapular bursitis in an HIV-positive patient receiving an antiretroviral regimen that included ritonavir boosted-atazanavir. University outpatient HIV clinic. A 60-year-old HIV-positive man on a ritonavir-boosted, atazanavir-containing antiretroviral regimen was diagnosed with subscapular bursitis. The patient received two intrabursal injections with 1% lidocaine plus triamcinolone 20 mg. Four weeks after the injections, the patient experienced symptoms of Cushing's syndrome with a pronounced drop in his CD4+ T-cell count, requiring treatment of oral candidiasis and prophylaxis for opportunistic infections. The interaction between ritonavir and oral corticosteroids, resulting in ICS, has been established. This case adds to the literature as one of the few cases illustrating that interaction can also occur between ritonavir and intrabursal administration of corticosteroids. This case further supports concerns regarding use of corticosteroids in HIV-infected patients who are treated with ritonavir-containing antiretroviral regimens.

    conducted. The sample was made up of 30 diabetic patients who were seen at "Dr Miguel Enríquez" clinical and surgical hospital from January to June 2007, with diagnosis of diabetic macular edema, and who met the inclusion criteria. RESULTS: Females prevailed and the 55-65 year age group was the most common. Length of development of the disease was associated with the presence of macular edema; it was evident that this pathology declined and that visual acuity improved after the treatment whereas no serious complications occurred. CONCLUSIONS: The use of triamcinolone acetonide through posterior subtenon way of administration is an alternative for the treatment of macular edema.

All 131 eyes received 4 mg IVTA at the end of surgery.Methods: Pre- and postoperative IOP, use of pressure-lowering medications, and rate of glaucoma surgery were analyzed. Pre-operative risk factors were analyzed.Main outcome measures: IOP, glaucoma medications, or glaucoma surgery.Results: Secondary ocular hypertension (defined as IOP ≥25 mmHg was found in 28 eyes (21%, the majority during postoperative day 1 only. Twelve eyes (9% had an elevated IOP measurement noted at a visit after the first postoperative day. Five (4% had an IOP rise of ≥10 mmHg over baseline at any time after postoperative day 1. Six (5% required glaucoma medications. One eye required a glaucoma drainage implant for diabetic neovascular angle closure glaucoma, and one eye required enucleation for intractable neovascular glaucoma due to radiation retinopathy. Elevated postoperative IOP was statistically associated with higher baseline IOP and presence of preoperative glaucoma.Conclusions: Therapeutic intravitreal triamcinolone with combined vitrectomy and phacoemulsification causes infrequent and usually mild secondary ocular hypertension. Secondary ocular hypertension is associated with preoperative glaucoma and high IOP.Keywords: glaucoma, cataract, inflammation

    Full Text Available Background : The calcium channel blocker, verapamil stimulates procollagenase synthesis in keloids and hypertrophic scars. Aim : To study the effect of verapamil in the treatment of hypertrophic scars and keloids and to evaluate the effect of verapamil on the rate of reduction of hypertrophic scars and keloids in comparison with triamcinolone. Methods : The study was a randomized, single blind, parallel group study in which 54 patients were allocated to to receive either verapamil or triamcinolone. Drugs were administered intralesionally in both groups. Improvement of the scar was measured using modified Vancouver scale and by using a centimeter scale serially till the scar flattened. Results : There was a reduction in vascularity, pliability, height and width of the scar with both the drugs after 3 weeks of treatment. These changes were present at one year of follow-up after stopping treatment. Scar pigmentation was not changed desirably by either drug. Length of the scars was also not altered significantly by either drug. The rate of reduction in vascularity, pliability, height and width of the scar with triamcinolone was faster than with verapamil. Adverse drug reactions were more with triamcinolone than with verapamil. Conclusion : Intralesional verapamil may be a suitable alternative to triamcinolone in the treatment of hypertrophic scars and keloids.

    Full Text Available Chronic expanding haematoma (CEH is a rare type of haematoma that enlarges slowly and continuously without coagulation. It can occur following surgery because of shear stress-induced bleeding in the scar tissue between the subcutaneous fat and fascia. We present three cases of large chronic CEH that were successfully treated with triamcinolone injections. Three female patients developed large chronic CEH at 9 months, 5 years, and 6 years, respectively, after latissimus dorsi flap harvesting for breast reconstruction. Although the condition did not improve after multiple sessions of haematoma aspiration in the first two patients, it resolved following a single 40-mg triamcinolone injection along with appropriate compression dressing for several weeks. In the third patient, triamcinolone was injected immediately after the initial aspiration of the haematoma, and the condition improved considerably. There were no side effects in any of the patients. To the best of our knowledge, this is the first report of successful treatment of large CEH using triamcinolone. Therefore, we suggest that triamcinolone injections be considered for the treatment of CEH.

    A comparison of the two methods of corticosteroid (triamcinolone) use in reducing supratip edema (pollybeak deformity) after rhinoplasty. Ninety patients who were candidates for rhinoplasty were randomly divided into three groups. Group A received no treatment, group B received 8 mg/mL of triamcinolone, and group C received 16 mg/mL of triamcinolone. Their effects on dorsal edema were evaluated by using the patients' and surgeons' visual analog scale scores. Also, dorsal edema was measured by using photo editing software. There was no significant difference in the patients' characteristics in the study groups. The surgeons' visual analog scale scores were significantly better in those patients who received triamcinolone injection than in the control group (p = 0.02). However, none of the other assessment methods showed significant differences among the study groups. There was no significant difference between the two evaluated concentrations. Triamcinolone injection had positive temporary effects on reducing supratip edema without any important complications.

  4. Ritonavir and epidural triamcinolone as a cause of iatrogenic Cushing's syndrome.

    2012-07-01

    Ritonavir is a protease inhibitor (PI) frequently prescribed with highly active antiretroviral therapy. It functions to boost the effectiveness of other PIs as a result of blocking their breakdown by the cytochrome P450 (3A4) pathway. Through this same mechanism, ritonavir has been shown to cause iatrogenic Cushing's syndrome (ICS) in patients using inhaled fluticasone. In addition, a small number of recent cases suggest that ritonavir may also cause this disorder by prolonging the duration of injected corticosteroids, such as triamcinolone. This case report presents a human immunodeficiency virus (HIV) patient taking ritonavir with ICS and secondary adrenal insufficiency, presumably due to systemic absorption and decreased metabolism of an epidural triamcinolone injection. To the authors knowledge, there have only been 4 previously reported cases describing ritonavir-potentiating ICS after receiving a corticosteroid epidural. This provides further proof that caution should be taken with nonparenteral use of triamcinolone in HIV patients on PIs.

    To compare the efficacy of intravitreal bevacizumab (IVB) injection alone or with intravitreal triamcinolone acetonide (IVB/IVT) versus macular photocoagulation (MPC) in bilateral diabetic macular edema (DME). In this study we revisited data from a subset of subjects previously enrolled in a randomized clinical trial. The original study included 150 eyes randomized to three treatment arms: 1.25 mg IVB alone, combined injection of 1.25 mg IVB and 2 mg IVT, and focal or modified grid MPC. To eliminate the possible effects of systemic confounders, we selected fellow eyes of bilaterally treated subjects who had undergone different treatments; eventually 30 eyes of 15 patients were re-evaluated at baseline, 6, 12, 18, and 24 months. Using mixed model analysis, we compared the treatment protocols regarding visual acuity (VA) and central macular thickness (CMT). Improvement in VA in the IVB group was significantly greater compared to MPC at months 6 and 12 (P = 0.037 and P = 0.035, respectively) but this difference did not persist thereafter up to 24 months. Other levels of VA were comparable at different follow-up intervals (all P > 0.05). The only significant difference in CMT was observed in favor of the IVB group as compared to IVB/IVT group at 24 months (P = 0.048). Overall VA was superior in IVB group as compared to MPC up to 12 months. Although the IVB group showed superiority regarding CMT reduction over 24 months as compared to IVB/IVT group, it was comparable to the MPC group through the same period of follow up.

    1989-01-01

    Pennsylvania Power and Light wanted to cover deteriorating concrete in unit 2 of its Susquehanna BWR with a smooth, durable, decontaminable coating. Traditionally, floors in the plant had been coated with epoxy paint, but many of these floors suffered delamination, and failed in three to five years. Painting with epoxy would also interrupt operations for as much as three days while the floor dried, yet critical instruments in some areas had to be monitored at least once per shift. In addition, conventional floor surface preparation produced dust and vibration around sensitive equipment. The solution was a dustless scabbling system for surface preparation, followed by the installation of a high-strength acrylic industrial floor known as Silakal. The work was carried out by Pentek. Silikal bonds to the underlying concrete, so that delamination of the floor will not occur even under severe traffic conditions. Another advantage of this type of flooring is that it cures in one hour, so floor resurfacing has only minimal impact on plant operations. (author)

Eighty patients with adhesive capsulitis of less than 6 months duration were randomized to one of four groups: Group A, injection of triamcinolone 20 mg and eight sessions of standardized physiotherapy; Group B, injection of triamcinolone 20 mg alone; Group C, placebo injection and eight sessions of standardized physiotherapy; or Group D, placebo injection alone. All subjects were given an identical home exercise programme. Outcome measures were assessed at 6 weeks and 16 weeks. The primary outcome measure was Shoulder Disability Questionnaire (SDQ) score. Secondary outcomes were measurement of pain using a visual analogue scale (VAS), global disability using VAS and range of passive external rotation. A two-way analysis of variance was used to explore the effects of corticosteroid injection and physiotherapy. At 6 weeks, the SDQ had improved significantly more in the groups receiving corticosteroid injection (P = 0.004). Physiotherapy improved passive external rotation at 6 weeks (P = 0.02) and corticosteroid injection improved self-assessment of global disability at 6 weeks (P = 0.04). There was no interaction effect between injection and physiotherapy. At 16 weeks, all groups had improved to a similar degree with respect to all outcome measures. Corticosteroid injection is effective in improving shoulder-related disability, and physiotherapy is effective in improving the range of movement in external rotation 6 weeks after treatment.

    Slips and falls contribute to occupational injuries and fatalities globally. Both floor slipperiness and floor roughness affect the occurrence of slipping and falling. Investigations on fall-related phenomena are important for the safety and health of workers. The purposes of this study were to: compare the perceived floor slipperiness before and after walking on the floor; compare the perceived floor slipperiness with and without shoes for males and females; discuss the perceived floor roughness based on barefoot walking; and establish regression models to describe the relationship between perceived floor slipperiness and actual friction of the floors. Male and female subjects walked on 3 m walkways with or without shoes. The perceived floor slipperiness ratings both before and after their walk were collected. The perceived floor slipperiness both before and after walking were significantly affected by both floor and surface conditions. Gender, floor, surface, and footwear conditions were all significant factors affecting the adjustment of perceived floor slipperiness. The subjects made more adjustment on perceived floor slipperiness rating when they had shoes on than when they were barefooted. Regression models were established to describe the relationship between perceived floor slipperiness and floor coefficient of friction. These models may be used to estimate perceived floor slipperiness, or in reverse, the coefficient of friction of the floor, so as to prevent slipping and falling in workplaces.

    Full Text Available We report a case of unusually long persistence of triamcinolone crystals after intra-vitreal injection. Crystals were noted on fundus examination predominantly confined to the posterior pole. Optical coherence tomography localized the crystals to the posterior hyaloidal surface. Over 6 years of follow-up the patient has retained good visual acuity and no observable changes in the retina. As the condition clinically resembles both crystalline maculopathy and asteroid hyalosis, we suggest the term ′drug-induced benign crystalline hyaloidopathy′.

    Full Text Available Introduction: Alopecia Areota is a chronic inflammatory disease that involves hair follicles, and sometimes nails, caused by T-cell mediated autoimmune mechanism. Current treatment modalities includes corticosteroids (oral, topical or intralesional, Minoxidil, Contact sensitizers like DNCB, DPCP and SADBE, Immunosuppressants like Methotrexate or Azathioprine, DMARDs like Sulfasalazine, and Phototherapy. Materials and methods: After taking consent, 40 patients treated with excimer light, 46 patients treated with triamcinolone injection intralesionally and 14 patients treated with topical minoxidil 5% were compared by their photographs taken prior to treatments, at 2 months and 6 months follow up. Results: Among the excimer group, 21/32 (61.76% with single patch and 1/6 (16.67% with multiple patches achieved >50% hair regrowth. Among Triamcinolone group, 23/30 (76.67% with single patch and 10/16 (62.5% with multiple patches achieved >50% hair regrowth. Among the Minoxidil group, 4/12 (33.33% with single patch and none .i.e 0/2 with multiple patches achieved >50% regrowth. Conclusion: After comparing the efficacy of Excimer light therapy, intralesional triamcinolone and 5% Minoxidil, it was concluded that intralesional triamcinolone seems to be the most efficacious. Multiple patches were more resistant than single patch. Scalp response much better than beard.

    The aim of this study was to establish a method for injecting corticosteroid into the rotator interval under sonographic guidance and to measure the effect on function, pain and range of motion after 4 and 12 weeks. This study involved a multicenter cohort trial and carried out at outpatient clinics of the physical medicine and rehabilitation departments in Oslo and Porsgrunn, Norway. 39 patients with adhesive capsulitis lasting between 3 and 12 months. Sonographic-guided corticosteroid and lidocaine injection into the rotator interval medial to the biceps tendon using 20 mg triamcinolon hexacetat and 3 ml 20 mg/ml xylocain. Change in the shoulder pain and disability index score (SPADI) after 12 weeks. The change in SPADI was 42 points (95 % confidence interval, 33-51). Changes in the secondary outcomes shoved highly statistically significant increase in active and passive range of motion. One ultrasound-guided corticosteroid injection into the rotator interval seems to give significant improvement in SPADI and active range of motion after 12 weeks. The protocol was evaluated by the research faculty at Oslo university hospital, dept of physical medicine. The study was regarded as regular clinical procedure as injections with triamcinolon already is standard treatment. No trial registration was obtained but the protocol presented the local ethics committee without comments.

    Lateral elbow pain is common with a population prevalence of 1%-3%. The study was a comparative trial to validate the efficacy of single injection of platelet-rich plasma (PRP) for tennis elbow as compared with single injections of triamcinolone and placebo (normal saline) over a short term period. Comparative trial with 3- and 6-month followup evaluated with visual analog scale (VAS) and facial pain scale (FPS). Our study included a total of eighty patients with unilateral or bilateral tennis elbows. The study population included patients between 20 and 40 years age group belonging to either sex with seventy unilateral and ten bilateral affections for more than 3-month duration. Patients suffering from elbow pain due to other problems or those who have received any form of injection were excluded from the study. One milliliter of 2% Xylocaine injection was given before injecting the proposed formulation under trial. VAS and FPS were used for scoring pain. Kruskal-Wallis test and Mann-Whitney U-tests were used for statistical analyses at 12 and 24 weeks. Overall, 49 females and 31 males were included with thirty elbows in each group. Both the PRP and triamcinolone groups had better pain relief at 3 and 6 months as compared to normal saline group ( P < 0.05), but at 6 months followup, the PRP group had statistically significant better pain relief than triamcinolone group. In the triamcinolone group, 13 patients had injection site hypopigmentation and 3 patients had subdermal atrophy. Over a short term period, PRP gives better pain relief than triamcinolone or normal saline in tennis elbow which needs to be validated over long term period by further studies.

    2014-10-01

    The successful treatment of women with vestibulodynia and its associated chronic pelvic floor dysfunctions requires interventions that address a broad field of possible pain contributors. Pelvic floor muscle hypertonicity was implicated in the mid-1990s as a trigger of major chronic vulvar pain. Painful bladder syndrome, irritable bowel syndrome, fibromyalgia, and temporomandibular jaw disorder are known common comorbidities that can cause a host of associated muscular, visceral, bony, and fascial dysfunctions. It appears that normalizing all of those disorders plays a pivotal role in reducing complaints of chronic vulvar pain and sexual dysfunction. Though the studies have yet to prove a specific protocol, physical therapists trained in pelvic dysfunction are reporting success with restoring tissue normalcy and reducing vulvar and sexual pain. A review of pelvic anatomy and common findings are presented along with suggested physical therapy management. Copyright © 2014 Elsevier Ltd. All rights reserved.

    ón del edema por tomografía de coherencia óptica. El tratamiento con acetato de triamcinolona intravítrea constituye una alternativa en la mejoría del edema macular diabético.It is estimated at present that there are 120 million diabetics worldwide and that the number of these patients doubles every 15 years. Some data is descriptive in reflecting the current situation: only 30 % of type I diabetics are properly controlled wheres and 7 % of type 2 diabetics of high risk have never been checked by any ophthalmologist in developed countries. The prevalence of diabetic retinopathy depends on the type of diabetes and the age of patient, so it decreases with the age. The most common type is the non-proliferative diabetic retinopahy found in 80 % versus the proliferative in 20 % of patients. Diabetes mellitus in Cuba has a prevalence rate of 1 per 10 000 pop. Recent studies yielded 20-25 % retinopathy prevalence in diabetic patients. Early detection and treatment of retinopathy and macular edema are essential for reducing visual disability in diabetics. This paper evaluated the effectiveness of intravitreal triamcinolone as general anti-angiogenic and anti-inflamatory theraphy for macular edema in a group of diabetic patients, who had been seen at “Ramón Pando Ferrer” Ophthalmology Institute from January to July, 2006. A prospective and descriptive case-control study was performed in which the patient was the control at the same time. The sample was made up of 30 diabetic patients diagnosed with diabetic macular edema and eligible for the use of this drug. Females aged over 6 years of age predominated; although the visual acuity improved, this did not match with the evident reduction of macular edema. Those patients with no previous laser treatment had a better response to the applied drug. The main post-treatment complications were ocular hypertension and edema involution. The intravitreal triamcinolone acetonide is a therapeutical choice for diabetic macular edema.

    Our goal is to provide an update on the results of pelvic floor rehabilitation in the treatment of urinary incontinence and genital prolapse symptoms. Pelvic floor muscle training allows a reduction of urinary incontinence symptoms. Pelvic floor muscle contractions supervised by a healthcare professional allow cure in half cases of stress urinary incontinence. Viewing this contraction through biofeedback improves outcomes, but this effect could also be due by a more intensive and prolonged program with the physiotherapist. The place of electrostimulation remains unclear. The results obtained with vaginal cones are similar to pelvic floor muscle training with or without biofeedback or electrostimulation. It is not known whether pelvic floor muscle training has an effect after one year. In case of stress urinary incontinence, supervised pelvic floor muscle training avoids surgery in half of the cases at 1-year follow-up. Pelvic floor muscle training is the first-line treatment of post-partum urinary incontinence. Its preventive effect is uncertain. Pelvic floor muscle training may reduce the symptoms associated with genital prolapse. In conclusion, pelvic floor rehabilitation supervised by a physiotherapist is an effective short-term treatment to reduce the symptoms of urinary incontinence or pelvic organ prolapse.

    We report two HIV-positive patients on highly active antiretroviral therapy (HAART) who developed clinical features in keeping with secondary adrenal suppression following epidural and subacromial triamcinolone. Both patients were on ritonavir-boosted protease inhibitor containing HAART and both required maintenance hydrocortisone therapy following diagnosis. This highlights the need for radiologists and clinicians practicing these injections to be aware of this complication, to elicit an accurate drug history, and to take adequate measures to minimize these adverse effects.

    To quantitatively compare short-term hard exudates (HEs) alteration in patients with diabetic macular edema (DME) after intravitreal triamcinolone, dexamethasone implant or bevacizumab injections. This retrospective study enrolled DME eyes with HEs that underwent a single-dose intravitreal injection of triamcinolone (25 eyes), dexamethasone implant (20 eyes), or three monthly injections of bevacizumab (25 eyes) and completed at least three months of follow-up. All patients were examined before and after 1, 2 and 3 months of injections. Using color fundus photographs, the amount of HEs was quantified by two masked graders. The difference in HEs area between baseline and each follow-up visit was compared among the three groups. After three months, HEs area was reduced to 52.9 ± 4.21% (P bevacizumab group. A significant reduction in HEs appeared at one month in the triamcinolone group (53.5 ± 4.91%, P bevacizumab does not. Therefore, intravitreal steroids may be useful in DME with HEs in the fovea.

    The electromagnetic precursors of seismic hazards are widely accepted as strong evidence of the approaching earthquake or volcano eruption. The monitoring of these precursors are of main interest in densely populated areas, what creates serious problems to extract them at the strong industrial noise background. An interesting possibility to improve signal-to-noise ratio gives the installation of the observation points in the shelf zones near the possible earthquake places, what is fairly possible in most seismically active areas in Europe, e. g. in Greece and Italy. The serious restriction for this is the cost of the underwater instrumentation. To realize such experiments it requires the unification of efforts of several countries (e. g., GEOSTAR) or of the funds of some great companies (e. g., SIO magnetotelluric instrument). The progress in electronic components development as well as the appearance of inexpensive watertight glass spheres made it possible to decrease drastically the price of recently developed sea floor magnetic stations. The autonomous vector magnetometer LEMI-301 for sea bed application is described in the report. It is produced on the base of three-component flux-gate sensor. Non-magnetic housing and minimal magnetism of electronic components enable the instrument to be implemented as a monoblock construction where the electronic unit is placed close to the sensor. Automatic circuit provides convenient compensation of the initial field offset and readings of full value (6 digits) of the measured field. Timing by internal clock provides high accuracy synchronization of data. The internal flash memory assures long-term autonomous data storage. The system also has two-axes tilt measurement system. The methodological questions of magnetometer operation at sea bed were studied in order to avoid two types of errors appearing at such experimental cases. First is sea waving influence and second one magnetometer orientation at its random positioning on

    The current study aimed to assess the value of microplasma radiofrequency technology combined with triamcinolone for the therapy of Chinese patients with hypertrophic scar. A total of 120 participants with hypertrophic scars were enrolled in the current study. Participants were divided into two groups based on sex, and then randomly and evenly divided into four groups (Groups A, B, C, and D). Participants in Group A received microplasma radiofrequency technology combined with triamcinolone. Participants in Group B received microplasma radiofrequency technology combined with normal saline. Participants in Groups C and D received triamcinolone (40 and 10 mg/mL) injected directly into scar. Experienced physicians evaluated the condition of scars according to the Vancouver Scar Scale 1 month before and after the therapy. There was no difference in age, sex, area, height and location of scars, and Vancouver Scar Scale scores before the therapy between any groups (P>0.05 for all). Vancouver Scar Scale scores after the therapy were significantly lower than those before the therapy in all groups (P0.05 for all). Incidences of tissue atrophy after the therapy were significantly lower in Groups A and B than in Group C (P0.05 for all). Microplasma radiofrequency technology combined with triamcinolone improved the therapeutic effect on Chinese patients with hypertrophic scar and reduced the risk of tissue atrophy compared with the use of either microplasma radiofrequency technology or triamcinolone injection alone.

    Physical therapists are uniquely qualified to treat pelvic floor dysfunction with conservative management techniques. Techniques associated with incontinence and support functions of the pelvic floor include bladder training and pelvic floor rehabilitation: pelvic floor exercises, biofeedback therapy, and pelvic floor electrical stimulation. Pain associated with mechanical pelvic floor dysfunction can be treated by physical therapists utilizing various manual techniques and modalities. Research documents that conservative management is effective in treating many conditions associated with pelvic floor dysfunction. Research should be conducted to determine if addressing diastasis recti and contracture of the pelvic floor musculature should be a component of the standard physical therapy protocol.

Methods: In a randomized controlled clinical trial, 30 phakic eyes with recent (less than 10 weeks′ duration BRVO were assigned to two groups. The treatment group (16 eyes received 4 mg IVT and the control group (14 eyes received subconjunctival sham injections. Changes in visual acuity (VA were the main outcome measure. Results: VA and central macular thickness (CMT changes were not significantly different between the study groups at any time point. Within group analysis showed significant VA improvement from baseline in the IVT group up to three months (P 0.05. Significant reduction in CMT was noticed only in the treatment group (‑172 ± 202 μm, P = 0.029 and at 4 months. Ocular hypertension occurred in 4 (25% and 2 (14.3% eyes in the IVT and control groups, respectively. Conclusion: A single IVT injection had a non-significant beneficial effect on VA and CMT in acute BRVO as compared to the natural history of the condition. The 3-month deferred treatment protocol advocated by the Branch Vein Occlusion Study Group may be a safer option than IVT injection considering its potential side effects.

    The placenta is a glucocorticoid target organ, and glucocorticoids (GCs) are essential for the development and maturation of fetal organs. They are widely used for treatment of a variety of diseases during pregnancy. In various tissues, GCs have regulated by glucose transport systems; however, their effects on glucose transporters in the human placental endothelial cells (HPECs) are unknown. In the present study, HPECs were cultured 24 h in the presence or absence of 0.5, 5 and 50 µmol · l(-1) of synthetic GC triamcinolone (TA). The glucose carrier proteins GLUT 1, GLUT 3 and GC receptor (GR) were detected in the HPECs. We showed increased expression of GLUT 1 and GLUT 3 proteins and messenger RNA (mRNA) levels (p GLUT 1 and GLUT 3 expression through GR. Excessive exposure to GCs causes maternal and fetal hypoglycemia and diminished fetal growth. We speculate that to compensate for fetal hypoglycemia and diminished fetal growth, the expression of placental endothelial glucose transporters might be increased.

Slow-release, nonbioerodible fluocinolone acetonide (FAc) implants have shown efficacy in the treatment of DMO; however, the National Institute for Health and Care Excellence recommends that FAc should be used in patients with chronic DMO considered insufficiently responsive to other available therapies only if the eye to be treated is pseudophakic. The goal of this analysis was to examine treatment outcomes in phakic patients who received 0.2 μg/day FAc implant. This analysis of the phase 3 FAME (Fluocinolone Acetonide in Diabetic Macular Edema) data examines the safety and efficacy of FAc implants in patients who underwent cataract extraction before (cataract before implant (CBI) group) or after (cataract after implant (CAI) group) receiving the implant. The data were further examined by DMO duration. Best corrected visual acuity (BCVA) after 36 months was comparable in the CAI and CBI groups. Both the percentage of patients gaining ≥ 3 lines of vision and mean change in BCVA letter score were numerically greater in the CAI group. In addition, most patients who underwent cataract surgery experienced a net gain in BCVA from presurgery baseline as well as from original study baseline. These data support the use of 0.2 μg/day FAc implants in phakic as well as in pseudophakic patients. These findings will serve as a pilot for design of future studies to evaluate the potential protective effect of FAc implants before cataract surgery in patients with DMO and cataract.

    Price floors in greenhouse gas emissions trading schemes can guarantee minimum abatement efforts if prices are lower than expected, and they can help manage cost uncertainty, possibly as complements to price ceilings. Provisions for price floors are found in several recent legislative proposals for emissions trading. Implementation however has potential pitfalls. Possible mechanisms are government commitments to buy back permits, a reserve price at auction, or an extra fee or tax on acquittal of emissions permits. Our analysis of these alternatives shows that the fee approach has budgetary advantages and is more compatible with international permit trading than the alternatives. It can also be used to implement more general hybrid approaches to emissions pricing. - Research highlights: → Price floors for emissions trading schemes guarantee a minimum carbon price. → Price floors mean that emissions can be less than specified by the ETS cap. → We examine how price floors can relate to different policy objectives. → We compare different mechanisms for implementing a price floor. → We find that a mechanism where there is an extra tax or fee has advantages.

    The purpose of this study was to compare the changes in the aqueous cytokine levels after intravitreal bevacizumab with those after combined intravitreal bevacizumab and subtenon triamcinolone injection in diabetic macular edema (DME). This study examined 24 eyes of 23 patients with DME. Each patient with DME received randomly either an intravitreal injection of bevacizumab (IVBe) or IVBe with a subtenon triamcinolone injection (IVBe + STTA). Best corrected visual acuity and foveal thickness were evaluated and aqueous samples were obtained before and 4 weeks after the injection. The aqueous concentrations of interleukin (IL)-6, IL-8, interferon-induced protein (IP)-10, monocyte chemotactic protein (MCP)-1, platelet-derived growth factor (PDGF)-AA, and vascular endothelial growth factor (VEGF) were measured using a multiplex bead assay. After the injection, the foveal thickness decreased more in the IVBe + STTA group than in the IVBe group (P = 0.042). The MCP-1, PDGF-AA, and VEGF levels decreased significantly in the IVBe + STTA group (p = 0.013, p = 0.004 and p = 0.018 respectively), but only the VEGF level decreased in the IVBe group (p = 0.001). IL-8 was significantly increased in the IVBe + STTA group (p = 0.003) but the changes in the VEGF levels were smaller than in the IVBe group (p = 0.025). Intravitreal bevacizumab and subtenon triamcinolone injection reduces the VEGF, MCP-1 and PDGF-AA levels and increases the IL-8 level in the plural cytokine profiles of patients with DME, which might explain the limited therapeutic effect of combination therapy.

    Generally, descriptions of the pelvic floor are discordant, since its complex structures and the complexity of pathological disorders of such structures; commonly the descriptions are sectorial, concerning muscles, fascial developments, ligaments and so on. On the contrary to understand completely nature and function of the pelvic floor it is necessary to study it in the most unitary view and in the most global aspect, considering embriology, philogenesy, anthropologic development and its multiple activities others than urological, gynaecological and intestinal ones. Recent acquirements succeeded in clarifying many aspects of pelvic floor activity, whose musculature has been investigated through electromyography, sonography, magnetic resonance, histology, histochemistry, molecular research. Utilizing recent research concerning not only urinary and gynecologic aspects but also those regarding statics and dynamics of pelvis and its floor, it is now possible to study this important body part as a unit; that means to consider it in the whole body economy to which maintaining upright position, walking and behavior or physical conduct do not share less than urinary, genital, and intestinal functions. It is today possible to consider the pelvic floor as a musclefascial unit with synergic and antagonistic activity of muscular bundles, among them more or less interlaced, with multiple functions and not only the function of pelvic cup closure.

    Full Text Available The occurrence of pelvic floor dysfunction may increase steadily during the aging process in women. Pelvic floor dysfunction may be associated with dysfunctions of micturition, defecation, prolapse, and sex. The natural history and mechanism of pelvic floor dysfunction in aged women are not well understood or explored. In this article, we review the effect of age on the prevalence of pelvic floor dysfunction and on the structural and functional changes of the lower urinary tract, anorectum and pelvic floor. Altogether, the aging process has a negative impact on either the function or structure of the lower urinary tract, anorectum and pelvic floor in women.

    Bottom trawling is a non-selective commercial fishing technique whereby heavy nets and gear are pulled along the sea floor. The direct impact of this technique on fish populations and benthic communities has received much attention, but trawling can also modify the physical properties of seafloor sediments, water–sediment chemical exchanges and sediment fluxes. Most of the studies addressing the physical disturbances of trawl gear on the seabed have been undertaken in coastal and shelf environments, however, where the capacity of trawling to modify the seafloor morphology coexists with high-energy natural processes driving sediment erosion, transport and deposition. Here we show that on upper continental slopes, the reworking of the deep sea floor by trawling gradually modifies the shape of the submarine landscape over large spatial scales. We found that trawling-induced sediment displacement and removal from fishing grounds causes the morphology of the deep sea floor to become smoother over time, reducing its original complexity as shown by high-resolution seafloor relief maps. Our results suggest that in recent decades, following the industrialization of fishing fleets, bottom trawling has become an important driver of deep seascape evolution. Given the global dimension of this type of fishery, we anticipate that the morphology of the upper continental slope in many parts of the world’s oceans could be altered by intensive bottom trawling, producing comparable effects on the deep sea floor to those generated by agricultural ploughing on land.

    Imaging for pelvic floor defaecatory dysfunction includes defaecation proctography. Integrated total pelvic floor ultrasound (transvaginal, transperineal, endoanal) may be an alternative. This study assesses ultrasound accuracy for the detection of rectocele, intussusception, enterocele and dyssynergy compared with defaecation proctography, and determines if ultrasound can predict symptoms and findings on proctography. Treatment is examined. Images of 323 women who underwent integrated total pelvic floor ultrasound and defaecation proctography between 2011 and 2014 were blindly reviewed. The size and grade of rectocele, enterocele, intussusception and dyssynergy were noted on both, using proctography as the gold standard. Barium trapping in a rectocele or a functionally significant enterocele was noted on proctography. Demographics and Obstructive Defaecation Symptom scores were collated. The positive predictive value of ultrasound was 73% for rectocele, 79% for intussusception and 91% for enterocele. The negative predictive value for dyssynergy was 99%. Agreement was moderate for rectocele and intussusception, good for enterocele and fair for dyssynergy. The majority of rectoceles that required surgery (59/61) and caused barium trapping (85/89) were detected on ultrasound. A rectocele seen on both transvaginal and transperineal scanning was more likely to require surgery than if seen with only one mode (P = 0.0001). If there was intussusception on ultrasound the patient was more likely to have surgery (P = 0.03). An enterocele visualized on ultrasound was likely to be functionally significant on proctography (P = 0.02). There was, however, no association between findings on imaging and symptoms. Integrated total pelvic floor ultrasound provides a useful screening tool for women with defaecatory dysfunction such that defaecatory imaging can avoided in some.

    Full Text Available Triamcinolone (TRI, a drug widely used in the treatment of ocular inflammatory diseases, is practically insoluble in water, which limits its use in eye drops. Cyclodextrins (CDs have been used to increase the solubility or dissolution rate of drugs. The purpose of the present study was to validate a UV-Vis spectrophotometric method for quantitative analysis of TRI in inclusion complexes with beta-cyclodextrin (B-CD associated with triethanolamine (TEA (ternary complex. The proposed analytical method was validated with respect to the parameters established by the Brazilian regulatory National Agency of Sanitary Monitoring (ANVISA. The analytical measurements of absorbance were made at 242nm, at room temperature, in a 1-cm path-length cuvette. The precision and accuracy studies were performed at five concentration levels (4, 8, 12, 18 and 20μg.mL-1. The B-CD associated with TEA did not provoke any alteration in the photochemical behavior of TRI. The results for the measured analytical parameters showed the success of the method. The standard curve was linear (r2 > 0.999 in the concentration range from 2 to 24 μg.mL-1. The method achieved good precision levels in the inter-day (relative standard deviation-RSD <3.4% and reproducibility (RSD <3.8% tests. The accuracy was about 80% and the pH changes introduced in the robustness study did not reveal any relevant interference at any of the studied concentrations. The experimental results demonstrate a simple, rapid and affordable UV-Vis spectrophotometric method that could be applied to the quantitation of TRI in this ternary complex. Keywords: Validation.

    Natural stone can be use on nearly every surface, inside and outside buildings, but decay is more commonly reported from the ones exposed to outdoor aggressively conditions. This study instead, is an example of limestone weathering of uncertain origin in the interior of a residential building. The stone, used as flooring, started to exhibit loss of material in the form of scaling. These damages were observed before the building, localized in the South of Spain (Málaga), was inhabited. Moreover, according to the company the limestone satisfies the following European standards UNE-EN 1341: 2002, UNE-EN 1343: 2003; UNE-EN 12058: 2004 for floorings. Under these circumstances the main objective of this study was to assess the causes of this phenomenon. For this reason the composition of the mortar was determined and the stone was characterized from a mineralogical and petrological point of view. The last material, which is a fossiliferous limestone from Egypt with natural fissure lines, is mainly composed of calcite, being quartz, kaolinite and apatite minor phases. Moreover, under different spectroscopic and microscopic techniques (FTIR, micro-Raman, SEM-EDX, etc) samples of the weathered, taken directly from the buildings, and unweathered limestone tiles were examined and a new mineralogical phase, trona, was identified at scaled areas which are connected with the natural veins of the stone. In fact, through BSE-mapping the presence of sodium has been detected in these veins. This soluble sodium carbonate would was dissolved in the natural waters from which limestone was precipitated and would migrate with the ascendant capilar humidity and crystallized near the surface of the stone starting the scaling phenomenon which in historic masonry could be very damaging. Therefore, the weathering of the limestone would be related with the hygroscopic behaviour of this salt, but not with the constructive methods used. This makes the limestone unable to be used on restoration

Eighty-two patients on stable therapy were allocated at random to receive intra-articular TH alone, TH and methotrexate (TH+M) or TH and rifampicin (TH+R). Pain was recorded by a weekly chart and analysed using the area under the curve (AUC), periods of total pain relief and duration of effect. Examinations and microwave thermography were performed by an independent meteorologist at baseline, 3 and 6 months. Using the AUC, pain was significantly better in the TH+R group compared with TH alone (P=0.039, Mann Whitney U). The median duration of improved pain scores was 13.5 weeks with TH alone, 10 with TH+M and 19 with TH+R. Examination and microwave thermography revealed improvements compared with baseline, but there were no significant differences between the groups. Eleven of 28 patients treated with TH + R developed a flare of post-injection pain. Whilst the addition of rifampicin improved pain relief, the occurrence of pain after injection remains a problem. Measures to minimize this are needed when TH+R is used.

    Identify good response predictors to intra-articular injection (IAI) with triamcinolone hexacetonide (TH). This study was carried out in rheumatoid arthritis (RA) patients (American College of Rheumatology criteria) submitted to IAI (mono, pauci or polyarticular injection). A "blinded" observer prospectively evaluated joints at one week (T1), four weeks (T4), twelve weeks (T12) and 24 weeks (T24) after IAI. Outcome measurements included Visual Analogue Scale (0-10 cm) at rest, in movement and for swollen joints. Clinical, demographic and variables related to injection at baseline were analyzed according to IAI response. We studied 289 patients with RA (635 joints) with a mean age of 48.7 years (±10.68), 48.5% of them Caucasians, VAS for global pain=6.52 (±1.73). Under univariate analysis, the variables relating the best responses following IAI (improvement > 70%) were: "elbow and metacarpophalangeal (MCP) IAI, and functional class II". Under multivariate analysis, "males" and "non-whites" were the predictors with the best response to IAI at T4, while "elbow and MCP IAI", "polyarticular injection", "use of methotrexate" and "higher total dose of TH" obtained the best response at T24. Several predictors of good response to IAI in patients with RA were identified. The best-response predictors for TH IAI of long term were "apply elbow and MCP IAI" and "apply polyarticular injection". Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

  20. Pelvic floor and sexual male dysfunction

    Directory of Open Access Journals (Sweden)

    Antonella Pischedda

    2013-04-01

    Full Text Available The pelvic floor is a complex multifunctional structure that corresponds to the genito- urinary-anal area and consists of muscle and connective tissue. It supports the urinary, fecal, sexual and reproductive functions and pelvic statics. The symptoms caused by pelvic floor dysfunction often affect the quality of life of those who are afflicted, worsening significantly more aspects of daily life. In fact, in addition to providing support to the pelvic organs, the deep floor muscles support urinary continence and intestinal emptying whereas the superficial floor muscles are involved in the mechanism of erection and ejaculation. So, conditions of muscle hypotonia or hypertonicity may affect the efficiency of the pelvic floor, altering both the functionality of the deep and superficial floor muscles. In this evolution of knowledge it is possible imagine how the rehabilitation techniques of pelvic floor muscles, if altered and able to support a voiding or evacuative or sexual dysfunction, may have a role in improving the health and the quality of life.

    Understanding the anatomic relationship of the pelvic floor muscles with the pelvic girdle, spine, and hips aids the rehabilitation provider in diagnosis, management, and appropriate referrals. The bony anatomy of the pelvic girdle consists of 3 bones and 3 joints. The pelvic floor muscles are comprised mainly of the levator ani muscles with somatic innervation from the lumbosacral plexus. The bony and muscular pelvis is highly interconnected to the hip and gluteal musculature, which together provide support to the internal organs and core muscles. Pelvic floor physiology is centered on bladder and bowel control, sexual functioning, and pregnancy. Copyright © 2017 Elsevier Inc. All rights reserved.

    This article discusses the background and appraisal of endoluminal ultrasound of the pelvic floor. It provides a detailed anatomic assessment of the muscles and surrounding organs of the pelvic floor. Different anatomic variability and pathology, such as prolapse, fecal incontinence, urinary incontinence, vaginal wall cysts, synthetic implanted material, and pelvic pain, are easily assessed with endoluminal vaginal ultrasound. With pelvic organ prolapse in particular, not only is the prolapse itself seen but the underlying cause related to the anatomic and functional abnormalities of the pelvic floor muscle structures are also visualized.

    This paper compares the attractiveness of floor trading and anonymous electronic trading systems. It is argued that in times of low information intensity the insight into the order book of the electronic trading system provides more valuable information than floor trading, but in times of high information intensity the reverse is true. Thus, the electronic system's market share in trading activity should decline in times of high information intensity. This hypothesis is tested by data on BUND...

    Full Text Available Abstract Introduction The aim of this clinical trial was to compare the degree of short term post-operative irritation after application of a triamcinolone/demeclocycyline based or a calcium hydroxide based provisional cement. Methods A total of 109 patients (55 female and 54 male; mean age: 51 ± 14 years with primary or secondary dentinal caries were randomly assigned to the two treatment groups of this biomedical clinical trial (phase III. Selection criteria were good systemic health and treated teeth, which were vital and showed no symptoms of pulpitis. Up to three teeth were prepared for indirect metallic restorations, and the provisional restorations were cemented with a triamcinolone/demeclocycyline (Ledermix or a calcium hydroxide (Provicol based material. The intensity of post-operative pain experienced was documented according to the VAS (4, 12, 20, 24, and 82 h and compared to VAS baseline. Results A total of 159 teeth were treated (Ledermix: 83 teeth, Provicol: 76 teeth. The minor irritation of the teeth, experienced prior to treatment, was similar in both groups; however, 4 h after treatment this value was significantly higher in the Provicol group than in the Ledermix group (p Conclusions The patients had no long term post-operative pain experience in both groups. However, within the first hours after cementation the sensation of pain was considerably higher in the Provicol group than in the Ledermix group.

    macular edema, the laser-photocoagulation had not the desired effects. AIMS: to review the present state of intravitreous route of Triamcinolone use acetate by in patients presenting this entity. DEVELOPMENT: Triamcinolone acetate is a corticoid agent with a potent anti-inflammatory and antiangiogenic action stabilizing the hematoretinal barrier and to inhibit the angiogenesis, thus, its use in diabetic macular edema treatment where the damage to above mentioned barrier and the release of angiogenic factors in response to hypoxia are closely involved in pathogenesis of this type of edema. Intravitreous administration in many dosages and not in few occasions in a repetitive way, has showed some controversial results in comparing the beneficial effect achieved by Triamcinolone acetate, with a short term effect and the concerns related to complications (ocular hypertension, endophthalmitis, vitreous hemorrhage, etc related to reinjections. Nowadays new devices are assayed releasing the Triamcinolone acetate in a slow way and lengthening its effect to find a more reasonable treatment strategy and with higher therapeutical effects than non-desirable ones. CONCLUSIONS: Triamcinolone acetate treatment is a alternative to improve the diabetic macular edema, although prospective studies and with a long-term follow-up period are needed to arrive to more consistent results.

    Solanki, Deepa; Schizas, Alexis M P; Williams, Andrew B

    2015-01-01

    Total pelvic floor ultrasound is used for the dynamic assessment of pelvic floor dysfunction and allows multicompartmental anatomical and functional assessment. Pelvic floor dysfunction includes defaecatory, urinary and sexual dysfunction, pelvic organ prolapse and pain. It is common, increasingly recognized and associated with increasing age and multiparity. Other options for assessment include defaecation proctography and defaecation MRI. Total pelvic floor ultrasound is a cheap, safe, imaging tool, which may be performed as a first-line investigation in outpatients. It allows dynamic assessment of the entire pelvic floor, essential for treatment planning for females who often have multiple diagnoses where treatment should address all aspects of dysfunction to yield optimal results. Transvaginal scanning using a rotating single crystal probe provides sagittal views of bladder neck support anteriorly. Posterior transvaginal ultrasound may reveal rectocoele, enterocoele or intussusception whilst bearing down. The vaginal probe is also used to acquire a 360° cross-sectional image to allow anatomical visualization of the pelvic floor and provides information regarding levator plate integrity and pelvic organ alignment. Dynamic transperineal ultrasound using a conventional curved array probe provides a global view of the anterior, middle and posterior compartments and may show cystocoele, enterocoele, sigmoidocoele or rectocoele. This pictorial review provides an atlas of normal and pathological images required for global pelvic floor assessment in females presenting with defaecatory dysfunction. Total pelvic floor ultrasound may be used with complementary endoanal ultrasound to assess the sphincter complex, but this is beyond the scope of this review. PMID:26388109

  11. WOODEN FLOORING – BETWEEN PRESENT AND FUTURE

    Full Text Available The paper aims at presenting a systematization of the wood floors, both in terms of the areas of application, and in terms of the fastening solutions and structures in constructions. In this respect, an extensive bibliographic research was achieved, on the researchers’ preoccupations. Starting from the current situation and forecasting the future, from the point of view of the chances held by wooden flooring, in competition with other types of materials, we dare say the wooden flooring or the wood in combination with other materials are not likely to be eliminated from the “civil-engineering market”. The wood floors are likely to develop as an application, especially in the area of the “special floors”, specific to the indoor sports or social halls; and even for some industrial sectors, with strict operating conditions (elasticity, thermal insulation, soundproofing that cannot be provided by other types of materials or structures. Starting from this last observation, the paper also aims at submitting current opinions with respect to this type of floors, both in the light of the current databases and in the light of the future researches, to this end

    Full Text Available Tile is no doubt rich in antiquity; its primordial  show, came as mosaic with primary prospect in sacred floor finish before its oblivion, courtesy of, later consciousness towards wall finish in banquets, kitchens, toilets, restaurants and even bars. Today, its renaissance as floor finish is apparent in private and public architectural structures with prevalence in residential, recreational, commercial, governmental and other spaces. In Nigeria, the use of glazed tiles as floor finish became apparent, supposedly in mid-twentieth century; and has since, witnessed ever increasing demands from all sundry; a development that is nascent and has necessitated its mass  production locally with pockets of firms in the country. The latter however, is a resultant response to taste cum glazed tiles affordability, whose divergent sophistication in design, colour, size and shape is believed preferred to terrazzo, carpet and floor flex tile. Accessible as glazed tile and production is, in recent times; its dearth of a holistic literature in Nigeria is obvious. In the light of the latter, this paper examine glazed tiles as floor finish in Nigeria, its advent, usage, production, challenge, benefit and prospect with the hope of opening further frontier in discipline specifics.

    To report an analysis of the concept 'pelvic floor health'. 'Pelvic floor health' is a term used by multiple healthcare disciplines, yet as a concept is not well defined. Rodger's evolutionary view was used to guide this analysis. Academic literature databases and public domain websites viewed via the Internet search engine Google. Literature in English, published 1946-July 2014 was reviewed. Websites were accessed in May 2014, then analysed of presentation for relevance and content until data saturation. Thematic analysis identified attributes, antecedents and consequences of the concept. Based on the defining attributes identified in the analysis, a contemporary definition is offered. 'Pelvic floor health' is the physical and functional integrity of the pelvic floor unit through the life stages of an individual (male or female), permitting an optimal quality of life through its multifunctional role, where the individual possesses or has access to knowledge, which empowers the ability to prevent or manage dysfunction. This analysis provides a definition of 'pelvic floor health' that is based on a current shared meaning and distinguishes the term from medical and lay terms in a complex, multifaceted and often under-reported area of healthcare knowledge. This definition provides a basis for theory development in future research, by focusing on health rather than disorders or dysfunction. Further development of the meaning is required in an individual's social context, to ensure a contemporaneous understanding in a dynamic system of healthcare provision. © 2015 John Wiley & Sons Ltd.

    Floor covering resistance (material and thickness) can be influenced by subjective choices (architectural design, interior design, texture, etc.) with significant effects on the performance of a radiant heating and cooling system. To study the effects of floor covering resistance on system...... performance, a water-based radiant floor heating and cooling system (dry, wooden construction) was considered to be coupled to an air-to-water heat pump, and the effects of varying floor covering resistances (0.05 m2K/W, 0.09 m2K/W and 0.15 m2K/W) on system performance were analyzed in terms of energy...... and exergy. In order to achieve the same heating and cooling outputs, higher average water temperatures are required in the heating mode (and lower temperatures in the cooling mode) with increasing floor covering resistance. These temperature requirements decrease the heat pump’s performance (lower...

    The Dermoid cyst account for the 0.01 % of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits. (author)

    Radioactive liquid wastes generated at BWR plants are collected and treated as required. These days, however, generation of floor drain has deceased and HFF (Hollow Fiber Filter) has experienced a wide applicability to several kinds of liquid wastes. We should consider that the floor drain can be mixed and diluted with equipment drain and be purified by HFF. That enables some of the sumps and long priming pipes to be combined. From this point of view, we have developed a highly rationalized waste liquid system. We have evaluated the applicability of this system after an investigation into the generation and properties of floor drain and equipment drain at the latest BWR'S and an on-site test at a typical BWR.

    Disorders of the posterior pelvic floor are relatively common. The role of imaging in this field is increasing, especially in constipation, prolapse and anal incontinence, and currently imaging is an integral part of the investigation of these pelvic floor disorders. Evacuation proctography provides both structural and functional information for rectal voiding and prolapse. Dynamic MRI may be a valuable alternative as the pelvic floor muscles are visualised, and it is currently under evaluation. Endoluminal imaging is important in the management of anal incontinence. Both endosonography and endoanal MRI can be used for detection of anal sphincter defects. Endoanal MRI has the advantage of simultaneously evaluating external sphincter atrophy, which is an important predictive factor for the outcome of sphincter repair. Many aspects of constipation and prolapse remain incompletely understood and treatment is partly empirical; however, imaging has a central role in management to place patients into treatment-defined groups.

    A lot of experts propose to dispose of the Co2 in the Oceans; but there is some confusion on that subject. The possibility of dispersing the Carbon Dioxide on the Ocean floor must be considered with great caution, carefully studying all the possible balances Co2 is subject to. A parameter which must be considered is the possibility for Co2 - whatever the form may be - of solving in the sea water, even when very deep. At the moment, the most safe way of storing the Co2 in the oceans seems to be the introduction of Co2 Hydrates into the sediments under the ocean floor [it

  20. Thermal Performance Analysis of Reinforced Concrete Floor Structure with Radiant Floor Heating System in Apartment Housing

    2015-01-01

    Full Text Available The use of the resilient materials in the radiant floor heating systems of reinforced concrete floor in apartment housing is closely related to the reduction of the floor impact sound and the heating energy loss. This study examined the thermal conductivity of expanded polystyrene (EPS foam used for the resilient material in South Korea and analysed the thermal transfer of reinforced concrete floor structure according to the thermal conductivity of the resilient materials. 82 EPS specimens were used to measure the thermal conductivity. The measured apparent density of EPS resilient materials ranged between 9.5 and 63.0 kg/m3, and the thermal conductivity ranged between 0.030 and 0.046 W/(m·K. As the density of resilient materials made of expanded polystyrene foam increases, the thermal conductivity tends to proportionately decrease. To set up reasonable thermal insulation requirements for radiant heating floor systems, the thermal properties of floor structure according to thermal insulation materials must be determined. Heat transfer simulations were performed to analyze the surface temperature, heat loss, and heat flow of floor structure with radiant heating system. As the thermal conductivity of EPS resilient material increased 1.6 times, the heat loss was of 3.4% increase.

  1. A Review of the Effectiveness and Side-Effects of Fluocinolone Acetonide 0.1% in the Treatment of Oral Mucosal Diseases

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Topical steroids have been widely used in the treatment of symptomatic oral lesions to reduce pain and inflammation. Potent topical steroids such as clobetasol propionate, fluocinolone acetonide (FA, and fluocinonide have been widely used in the treatment of severe oral mucosal lesions. Many reports have demonstrated that these steroids were effective in treating oral lesions with only minor side-effects. This review describes the effectiveness and side-effects of using FA 0.1% in the treatment of symptomatic oral lichen planus (OLP, oral lichenoid drug reaction (OLDR, oral pemphigus, and herpes associated erythema multiforme (HAEM. FA 0.1% was effective and safe in the treatment of patients with multiple systemic diseases and a pregnant patient with HAEM. Moreover, this topical steroid rapidly reduced pain, inflammation, and enhanced lesion healing with no serious side-effects other than pseudomembranous candidiasis, which is easily treated. In some cases, a long-term treatment with FA 0.1% resulted in hyperpigmentation at the areas of previously healed oral lesions; however, this hyperpigmentation was gradually resolved after discontinuing topical steroid treatment.

    Paradoxical contraction of the pelvic floor during attempts to defaecate is described as pelvic floor dyssynergia (anismus). It is a behavioural disorder (no associated morphological or neurological abnormalities); consequently, biofeedback training has been recommended as a behavioural therapy for such a disorder. The aim of the present study was to evaluate long-term satisfaction of patients diagnosed with pelvic floor dyssynergia after biofeedback. Sixty patients (35 females and 25 males) with a mean age of 30±12years and a 4year duration of constipation were included. Forty-five patients had normal colonic transit and 15 patients had slow colonic transit. History, physical examination and barium enema were done to exclude constipation secondary to organic causes. Colonic and pelvic floor functions (colon-transit time, anorectal manometry, EMG and defaecography) were performed before and after biofeedback treatments. Patients were treated on a weekly basis with an average of (6±2) sessions. At the end of sessions, 55 out of 60 patients (91.6%) reported a subjectively overall improvement. Symptoms of dyschezia were reported less frequently after biofeedback. Age and gender were not predictive factors of outcome. No symptoms at initial assessment were predictive for patient's satisfaction but the only factor of predictive value was the diagnosis of anismus and the motivated patient who wanted to continue the sessions. Biofeedback remains a morbidity free, low-cost and effective outpatient therapy for well-motivated patients complaining of functional constipation and diagnosed as pelvic floor dyssynergia.

  10. Functional imaging of the pelvic floor

    Energy Technology Data Exchange (ETDEWEB)

    Lienemann, Andreas E-mail: andreaslienemann@web.de; Fischer, Tanja

    2003-08-01

    Introduction/Objective: Pelvic floor dysfunction and associated pelvic organ prolapse represent a major problem in our present-day society, mostly afflicting parous women. Magnetic resonance imaging (MRI) is assuming an increasingly important role in the more accurate delineation of the extent of the problem. This article briefly reviews one of the main radiological methods for the dynamic evaluation of the pelvic floor: functional cine MRI. Methods and Material: Out of the literature the smallest common denominator for functional cine MRI can be defined as follows: high field system; patient either in supine or sitting position; fast gradient echo sequence; midsagittal slice orientation; either a stack of slices or repeated measurements at the same slice position with the patient at rest or straining; image analysis using the pubococcygeal reference line. Results: All except two publications stress the usefulness of functional cine MRI in the evaluation of patients with organ descent and prolapse. This well accepted method allows for the visualization of all relevant structures in the anterior, middle and posterior compartment. It is especially useful in the detection of enteroceles, and provides a reliable postoperative follow-up tool. Isolated urinary or stool incontinence are not an indication for functional cine MRI, as is the case in patients with equivocal clinical findings. To date it does not allow for real 3D imaging of the pelvic floor or sufficient determination of fascial defects. Discussion: Functional cine MRI of the pelvic floor is a promising new imaging method for the detection of organ descent and prolapse in patients with equivocal clinical findings. The combination of function and morphology allows for an innovative view of the pelvic floor, and thus adds to our understanding of the various interactions of the structures.

    The rate of urinary incontinence after prostatectomy, as reported in several studies, varies between 0 and 88%. In the last years, pelvic floor rehabilitation in the women stress incontinence has been strengthened, with a great amount of clinical studies and results. Recently, the rehabilitation treatment has been studied in men who underwent a radical prostatectomy. The Cochrane Database of Systematic Reviews recently published the "Conservative management for post prostatectomy incontinence". The aim of this study was to determine the effects of conservative management in post prostatectomy urinary incontinence. Randomized or almost-randomized trials were analyzed up to January 1999; five studies were included, with the following results: 1. Pelvic floor muscle training versus no active treatment. Two trials compared pelvic floor muscle training with patients in a control group. In both groups there was a clinical improvement, especially in the first months after prostatectomy. The results of the two studies suggest a benefit in the treated group, even if not statistically significant, mainly in the first months after surgery. 2. Pelvic floor muscle training + biofeedback versus no active treatment. The treated group regained continence in shorter time, with decrease of incontinence episodes, of urinary frequency, of the quantity of urine loss; these data were not statistically significant. 3. Pelvic floor muscle training + rectal electrical stimulation versus no active treatment No detectable differences among the two groups, either in number of men still incontinent, and in Pad-test results. 4. Pelvic floor muscle training + rectal electrical stimulation + biofeedback versus no active treatment. Pad-test evaluation was similar in the treated and in the control group; no other outcomes were described. 5. Pelvic floor muscle training + rectal electrical stimulation versus pelvic floor muscle training. There was a progressive improvement in three months of

  9. RFID Data Cleaning for Shop Floor Applications

    Science.gov (United States)

    Ziekow, Holger; Ivantysynova, Lenka; Günter, Oliver

    In several case studies we found that shop-floor applications in manufacturing pose special challenges to cleaning RFID data. The underlying problem in many scenarios is the uncertainty about the exact location of observed RFID tags. Simple filter s provided in common middleware solutions do not cope well with these challenges. Therefore we have developed an approach based on maximum-likelihood estimation to infer a tag's location within the reader range. This enables improved RFID data cleaning in a number of application scenarios. We stress the benefits of our approach along exemplary application scenarios that we found in manufacturing. In simulations and experiments with real world data we show that our approach outperforms existing solutions. Our approach can extend RFID middleware or reader firmware, to improve the use of RFID in a range of shop-floor applications.

    Sreekumar, K.; Gangamohan, M.; Kannan, R.K.; Rajan, S.

    2005-01-01

    Contamination check of floors and walkways in and around Reactor building areas forms an integral part of Radiation Protection Program in Power Stations. Though random swipe check method is adopted for the detection of loose contamination, this method has the disadvantage of leaving the fixed contamination and hotspots undetected. Hence, scanning the area with a sensitive detector, held close to the surface provides positive means for the detection of contamination. Checking large areas and walkways by holding the detector close to the surface involves physical work. Also, areas which are unapproachable due to congestion of equipment, may go uncovered by contamination monitoring in order to eliminate the physical strain involved in such contamination monitoring and to cover unapproachable areas, a small size prototype device that can be operated remotely was fabricated. This device detects contamination instantaneously and accurately. This paper describes design and fabrication of the device used for floor contamination monitoring. (author)

    Orbital floor fractures of varying sizes commonly occur after orbital injuries and remain a serious challenge. Serious complications of such fractures include enopthalmos, restriction of extraocular movement, and diplopia. There is a dearth of literature that can be applied widely, easily, and successfully in all such situations, and therefore there is no consensus on the treatment protocol of this pathology yet. Autogenous grafts and alloplastic and allogenic materials with a wide variety of advantages and disadvantages have been discussed. The value of preoperative and postoperative ophthalmological examination should be standard of care in all orbital fracture patients. An ideal reconstructed orbital floor fracture should accelerate the restoration of orbital function with acceptable cosmetic results. Management parameters of orbital fractures such as timing of surgery, incision type, and implant materials, though widely discussed, remain controversial. In this study, 55 patients with orbital floor fractures surgically reconstructed with conchal cartilage grafts between 2008 and 2014 were retrospectively evaluated. Complications and long-time follow-up visit results have been reported with clinical and radiographic findings. The aim of this study was to present the authors' clinical experiences of reconstruction of blow-out fractures with auricular conchal graft and to evaluate the other materials available for use.

    We describe a proactive method using electronic patient records (EPR) to identify pseudophakic patients with diabetic macular oedema (DMO) that might benefit from treatment with 0.2 µg/day fluocinolone acetonide (FAc; ILUVIEN(®)) implant. Our EPR audit tool (Medisoft(®)) identified diabetic patients (May 2011-December 2014) with National Screening Committee-confirmed grade M1 maculopathy. Searches segmented this DMO patient population into patient groups who: (1) had received ranibizumab therapy, (2) had received ≥2 macular laser treatments, or (3) were unsuitable for macular laser or ranibizumab therapy. Pre-specified criteria identified patients insufficiently responsive to treatment, and their electronic case notes were flagged for clinicians to consider FAc, based on National Institute for Health and Care Excellence (NICE) TA301. Using this methodology, 138 patients with DMO were identified, of whom 87 were assigned to group 1, 32 to group 2, and 29 to group 3 (10 patients were included in both groups 2 and 3). From these, 28 different pseudophakic eyes were identified as suitable for treatment with FAc, based on insufficient response to prior treatment. EPR audit offers a real-world methodology to efficiently identify patients that might benefit from treatment with FAc. Limitations apply, and thorough documentation of lens status and ocular comorbidities is vital; however, this approach was more rapid than prospective recruitment through the clinic. Flagging patient records using EPR audit offers a practical process for application to clinical practice, thereby optimizing patient care in line with NICE TA301 guidelines. Alimera Sciences Ltd.

  18. Pelvic floor dysfunction in inflammatory bowel disease.

    Science.gov (United States)

    Bondurri, A; Maffioli, A; Danelli, P

    2015-12-01

    Advances in tailored medical therapy and introduction of biologic agents for inflammatory bowel disease (IBD) treatment have ensured long-term disease remission. Some patients, however, still report defecatory symptoms. Patients present with a wide spectrum of conditions - anal incontinence, obstructed defecation and pelvic pain among the most frequent - that have a great impact on their quality of life. Due to IBD diagnosis, little relevance is attributed to this type of symptoms and their epidemiologic distribution is unknown. Pathogenetic hypotheses are currently under investigation. Routine diagnostic workflow and therapeutic options in pelvic floor service are often underused. The evaluation of these disorders starts with an endoscopy to rule out ongoing disease; the following diagnostic workflow is the same as in patients without IBD. For fecal incontinence and obstructed defecation, simple conservative therapy with dietary modifications and appropriate fluid intake is effective in most cases. In non-responding patients, anorectal physiology tests and imaging are required to select patients for pelvic floor muscle training and biofeedback. These treatments have been proven effective in IBD patients. Some new minimally invasive alternative strategies are available for IBD patients, as sacral nerve and posterior tibial nerve stimulation; for other ones (e.g., bulking agent implantation) IBD still remains an exclusion criterion. In order to preserve anatomical areas that could be useful for future reconstructive techniques, surgical options to cure pelvic floor dysfunction are indicated only in a small group of IBD patients, due to the high risk of failure in wound healing and to the possible side effects of surgery, which can lead to anal incontinence or to a possible proctectomy. A particular issue among defecatory symptoms in patients with IBD is paradoxical puborectalis contraction after restorative proctocolectomy: if this disorder is properly diagnosed, a

  19. Investigation of Floor Surface Finishes for Optimal Slip Resistance Performance

    Directory of Open Access Journals (Sweden)

    In-Ju Kim

    2018-03-01

    Full Text Available Background: Increasing the slip resistance of floor surfaces would be desirable, but there is a lack of evidence on whether traction properties are linearly correlated with the topographic features of the floor surfaces or what scales of surface roughness are required to effectively control the slipperiness of floors. Objective: This study expands on earlier findings on the effects of floor surface finishes against slip resistance performance and determines the operative ranges of floor surface roughness for optimal slip resistance controls under different risk levels of walking environments. Methods: Dynamic friction tests were conducted among three shoes and nine floor specimens under wet and oily environments and compared with a soapy environment. Results: The test results showed the significant effects of floor surface roughness on slip resistance performance against all the lubricated environments. Compared with the floor-type effect, the shoe-type effect on slip resistance performance was insignificant against the highly polluted environments. The study outcomes also indicated that the oily environment required rougher surface finishes than the wet and soapy ones in their lower boundary ranges of floor surface roughness. Conclusion: The results of this study with previous findings confirm that floor surface finishes require different levels of surface coarseness for different types of environmental conditions to effectively manage slippery walking environments. Collected data on operative ranges of floor surface roughness seem to be a valuable tool to develop practical design information and standards for floor surface finishes to efficiently prevent pedestrian fall incidents. Keywords: floor surface finishes, operational levels of floor surface roughness, slip resistance, wet, soapy and oily environments

  20. VOC- and SVOC-emissions from adhesives, floor coverings and complete floor structures.

    Science.gov (United States)

    Wilke, Olaf; Jann, Oliver; Brödner, Doris

    2004-01-01

    Emissions of volatile organic compounds (VOC) and semivolatile organic compounds (SVOC) from materials for flooring installation (primer, screed, adhesive, floor covering) were measured by means of emission test chambers and cells over a time period of at least 28 days at 23 degrees C, 50% relative humidity and an area specific air flow rate of q = 1.25 m(3)/m(2) h. Single components were tested in comparison to three complete structures (same concrete, primer, screed, adhesive) with different types of floor covering (PVC, carpet, linoleum). Sorption into concrete/screed and different permeability of flooring materials affected the emissions from the complete structures. The complete structures with linoleum and PVC showed the same types of emission and emission rates as the individual floor coverings themselves. Emissions from the carpet-covered structure resulted also from the lower layers. In all cases emissions from the complete structures were lower than the sum of emissions from the single components. For two adhesives the formation of secondary emissions (aldehydes and organic acids) was observed starting after the standard testing time of 28 days. This paper gives a survey of possible emissions of VOCs and SVOCs from flooring materials and adhesives. On the example of these materials it is shown that the determination of SVOC-emissions from materials is important because after a few weeks the emission rates for SVOCs might be higher than for VOCs. In the real indoor environment SVOCs will be probably adsorbed to dust but by means of emission test chambers or cells the determination of emission rates from materials is possible. With the knowledge of this "emission potential" it is possible to estimate also the release of SVOCs into the (indoor) environment.

    2014-01-01

    Recently, many residents living in apartment buildings in Korea have been bothered by noise coming from the houses above. In order to reduce noise pollution, communities are increasingly imposing bylaws, including the limitation of floor impact sound, minimum thickness of floors, and floor soundproofing solutions. This research effort focused specifically on the deflection of resilient materials in the floor sound insulation systems of apartment houses. The experimental program involved conducting twenty-seven material tests and ten sound insulation floating concrete floor specimens. Two main parameters were considered in the experimental investigation: the seven types of resilient materials and the location of the loading point. The structural behavior of sound insulation floor floating was predicted using the Winkler method. The experimental and analytical results indicated that the cracking strength of the floating concrete floor significantly increased with increasing the tangent modulus of resilient material. The deflection of the floating concrete floor loaded at the side of the specimen was much greater than that of the floating concrete floor loaded at the center of the specimen. The Winkler model considering the effect of modulus of resilient materials was able to accurately predict the cracking strength of the floating concrete floor.

    2016-02-01

    Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for

    2010-01-01

    The objective of this study was to quantify the proportion of kneeling work activities among floor layers and to assess external knee joint forces in five different kneeling work positions. Thirty-three floor layers were videotaped discontinuously and four floor layers were videotaped continuously...... for a whole working day. External knee forces were measured in five different kneeling work positions in ten floor layers using Computer Dynography. The study showed that floor layers spent a high percentage of time in knee-straining work positions. Kneeling work tasks, particularly gluing and crawling caused...... high external knee forces ranging from 0.3 Newton (SD 0.2) times body weight when floor layers were kneeling back on the heels, to 3.5 Newton (SD 0.3) times body weight in the crawling work position. The study highlights the need for prevention by minimizing the amount of kneeling work positions among...

    Orbital floor fractures are commonly seen in clinical practice, yet the etiology underlying the mechanism of fracture is not well understood. Current research focuses on the buckling theory and hydraulic theory, which implicate trauma to the orbital rim and the globe, respectively. To elucidate and define the biomechanical factors involved in an orbital floor fracture. A total of 10 orbits from 5 heads (3 male and 2 female) were used for this study. These came from fresh, unfixed human postmortem cadavers that were each selected so that the cause of death did not interfere with the integrity of orbital walls. Using a drop tower with an accelerometer, we measured impact force on the globe and rim of cadaver heads affixed with strain gauges. The mean impacts for rim and globe trauma were 3.9 J (95% CI, 3.4-4.3 J) and 3.9 J (95% CI, 3.5-4.3 J), respectively. Despite similar impact forces to the globe and rim, strain-gauge data displayed greater mean strain for globe impact (6563 μS) compared with rim impact (3530 μS); however, these data were not statistically significant (95% CI, 3598-8953 μS; P = .94). Our results suggest that trauma directly to the globe predisposes a patient to a more posterior fracture while trauma to the rim demonstrates an anterior predilection. Both the hydraulic and buckling mechanisms of fracture exist and demonstrate similar fracture thresholds. NA.

    The study aimed to investigate sacral peripheral nerve function and continuity of pudendal nerve in patients with chronic spinal cord injury (SCI) using pelvic floor electrophysiological tests. Twelve patients with low cervical or thoracic SCI were prospectively included. Quantitative external anal sphincter (EAS) muscle electromyography (EMG), pudendal nerve terminal motor latency (PNTML) testing, bulbocavernosus reflex (BCR) testing and pudendal short-latency somatosensory-evoked potential (SEP) measurement were performed. In EAS muscle EMG, two patients had abnormal increased spontaneous activity and seven prolonged motor unit potential duration. PNTML was normal in 10 patients. BCR was present with normal latency in 11 patients and with prolonged latency in one. The second component of BCR could be recorded in four patients. SEPs showed absent cortical responses in 11 patients and normal latency in one. Pudendal nerve and sacral lower motor neuron involvement are significantly associated with chronic SCI, most prominently in EAS muscle EMG. The frequent finding of normal PNTML latencies supports earlier concerns on the utility of this test; however, BCR and pudendal SEPs may have clinical relevance. As intact peripheral nerves including pudendal nerve are essential for efficient supportive therapies, pelvic floor electrophysiological testing prior to these interventions is highly recommended.

    To determine the effect of pelvic floor muscle exercises combined with electrical stimulation of pelvic floor on lower urinary tract dysfunction in multiple sclerosis (MS) patients with near normal (current symptoms of lower urinary tract dysfunction. The muscle activity of the pelvic floor muscles was tested using surface EMG. Subjective urinary symptoms were assessed using a questionnaire. Pelvic floor muscles were stimulated using electrical stimulation at six sessions. During and after the final session the patients were taught to exercise their pelvic floor muscles and advised to continue these exercises regularly for at least six months. The control group was not treated. The maximal contraction power and endurance of the pelvic floor muscles increased after six sessions of electrical stimulation with interferential currents. Symptoms of urinary urgency, frequency and incontinence were significantly less frequent in the treated group than in the untreated subjects. Male patients appeared to respond better to the treatment than female patients. Compliance with the pelvic floor exercises was over 60% at the end of a follow-up for six months. Most drop-outs were due to the disappearance of urinary tract symptoms or to severe relapses in MS. The present study indicates that pelvic floor muscle exercises combined with electrical stimulation of the pelvic floor constitute an effective treatment for lower urinary tract dysfunction at least in male patients with MS.

    2016-03-01

    As the field of reconstructive pelvic surgery continues to evolve, with descriptions of new procedures to repair pelvic organ prolapse, it remains imperative to maintain a functional understanding of pelvic floor anatomy and support. The goal of this review was to provide a focused, conceptual approach to differentiating anatomic defects contributing to prolapse in the various compartments of the vagina. Rather than provide exhaustive descriptions of pelvic floor anatomy, basic pelvic floor anatomy is reviewed, new and historical concepts of pelvic floor support are discussed, and relevance to the surgical management of specific anatomic defects is addressed.

    Telezhenko, E; Magnusson, M; Bergsten, C

    2017-08-01

    This study assessed the slip resistance of different types of solid flooring in cattle housing using a range of technical tests and gait analysis. Dynamic and static coefficient of friction, skid resistance, and abrasiveness were tested on concrete flooring with a smooth finish, a grooved pattern, or a tamped pattern, acid-resistant mastic asphalt, soft rubber mats, and a worn slatted concrete floor. Coefficients of friction and skid resistance were tested under clean and slurry-soiled conditions. Linear kinematic variables were assessed in 40 cows with trackway measurements after the cows passed over the floors in a straight walk. All gait variables were assessed as deviations from those obtained on the slatted concrete floor, which was used as a baseline. The coefficient of friction tests divided the floors into 3 categories: concrete flooring, which had a low coefficient of friction (0.29-0.41); mastic asphalt flooring, which had medium values (0.38-0.45); and rubber mats, which had high values (0.49-0.57). The highest abrasion (g/10 m) was on the asphalt flooring (4.48), and the concrete flooring with a tamped pattern had significantly higher abrasiveness (2.77) than the other concrete floors (1.26-1.60). Lowest values on the skid-resistance tests (dry/wet) were for smooth concrete (79/35) and mastic asphalt (65/47), especially with a slurry layer on the surface. Gait analysis mainly differentiated floors with higher friction and abrasion by longer strides and better tracking. Step asymmetry was lower on floors with high skid-resistance values. The most secure cow gait, in almost every aspect, was observed on soft rubber mats. Relationships between gait variables and physical floor characteristics ranged from average to weak (partial correlations 0.54-0.16). Thus, none of the physical characteristics alone was informative enough to characterize slip resistance. With reference to gait analysis, the abrasiveness of the hard surfaces was more informative than the

    The aim of this study was to investigate the effects of intra-articular injection of polydeoxyribonucleotide (PDRN), compared with intraarticular triamcinolone (TA) injection, in subacute stroke patients with hemiplegic shoulder pain (HSP).Participants were subacute stroke patients with HSP who had undergone 2 consecutive intra-articular injections of TA or PDRN.Numeric rating scale (NRS) and passive range of motion (PROM) of hemiplegic shoulder were evaluated until 4 weeks after 2nd injection.In the results, there were significant improvements in all PROM measures 2 weeks after the second injection, compared with pre-injection results, in both groups (P < .05). In the PDRN group, however, none of the PROM measures were significantly improved at 3 and 4 weeks after the second injection, compared with pre-injection results (P ≥ .05). When comparing pre-injection results with those at 4 weeks after the second injection, all PROM and NRS measures in the TA group were more improved than in the PDRN group, but this was not statistically significant (P ≥ .05).In conclusion, considering the systemic side effects of steroids, especially among patients with diabetes or metabolic syndrome, PDRN seems to be a worthwhile treatment option for HSP, although PDRN does not seem to have an equivalent persistence effects when compared with TA.

  15. PHYSICAL ACTIVITY AND THE PELVIC FLOOR

    2015-01-01

    Pelvic floor disorders (PFDs) are common, with one in four U.S. women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review is to summarize studies reporting the association between physical activity and PFDs. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include: Urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this exam finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for women. However

    2008-12-01

    This investigation shows that, in most cases, the floor cleaning procedure of typical restaurants could be improved, resulting in a better cleaning efficiency and a better floor friction. This simple approach could help reduce slips and falls in the workplace. Food safety officers visited ten European style restaurants in the London Borough of Bromley (UK) to identify their floor cleaning procedure in terms of the cleaning method, the concentration and type of floor cleaner and the temperature of the wash water. For all 10 restaurants visited, the cleaning method was damp mopping. Degreasers were used in three sites while neutral floor cleaners were used in seven sites. Typically, the degreasers were over diluted and the neutrals were overdosed. The wash water temperature ranged from 10 to 72 degrees C. The on-site cleaning procedures were repeated in the laboratory for the removal of olive oil from new and sealed quarry tiles, fouled and worn quarry tiles and new porcelain tiles. It is found that in 24 out of 30 cases, cleaning efficiency can be improved by simple changes in the floor cleaning procedure and that these changes result in a significant improvement of the floor friction. The nature of the improved floor cleaning procedure depends on the flooring type. New and properly sealed flooring tiles can be cleaned using damp mopping with a degreaser diluted as recommended by the manufacturer in warm or hot water (24 to 50 degrees C). But as the tiles become worn and fouled, a more aggressive floor cleaning is required such as two-step mopping with a degreaser diluted as recommended by the manufacturer in warm water (24 degrees C).

    A test program was developed and coordinated with State and Federal Regulators and carried out at Fort Sill, Oklahoma. This program was carefully designed to create the worst conditions in order to evaluate whether asbestos fibers are released when asbestos containing floor tile and mastic are removed. There were over 1,000 samples taken and analyzed during the execution of the program. The conclusions reached were based upon analysis of the critical samples using the Transmission Electron Microscope (TEM) technology. Additionally, the TEM procedures were used to evaluate personnel samples to determine whether those fibers found were asbestos or other materials. Most of the (TEM) samples were analyzed by the US Environmental Protection Agency (EPA) Risk Reduction Engineering Laboratory in Cincinnati, Ohio.

    1980-05-01

    The behavioral and strength characteristics of composite steel deck floor slab diaphragms are reported. Principal characteristics investigated include maximum load, ductility, stiffness, and failure mode. The addition of studs increases the flexural load capacity of one-way steel deck reinforced slabs by 10 to 30 percent. Non-studded specimens ultimately fail because of loss of interfacial force in the shear span. Studded specimens ultimately fail due to tearing of the deck near the stud. Two analysis procedures were used, a contributing forces approach and a shear-bond approach. The former was found to be a potential analysis procedure, and results from the shear-bond increase approach demonstrated its feasibility for studded specimens.

    The focus of this work is to validate the fluid model with different flooring materials and the measurements of an instrument to test flooring materials and its force attenuating capabilities using mathematical models to describe the signature and coefficients of the floor. The main contribution of the present work focus on the development of a mathematical fluid model for floors. The aim of the thesis was to analyze, compare different floor materials and to study the linear dynamics of falling impacts on floors. The impact of the hammer during a fall is captured by an accelerometer and response is collected using a picoscope. The collected data was analyzed using matlab least square method which is coded as per the fluid model. The finding from this thesis showed that the fluid model works with more elastic model but it doesn’t work for rigid materials like wood. The importance of parameters like velocity, mass, energy loss and other coefficients of floor which influences the model during the impact of falling on floors were identified and a standardized testing method was set.

    Although a relationship between pelvic floor dysfunction and lower urinary tract symptoms is described in the literature, the mechanism and pathways need further characterization. We developed an animal model of pelvic floor dysfunction after noxious stimulation of the pubococcygeus (PC) muscle. Fifteen female adult rabbits were evaluated with cystometry (CMG) and electromyography (EMG) recordings from the PC muscle. Cystometry/EMG was performed before and after treatment animal (n = 11) received noxious pelvic floor electrical stimulation through the PC EMG electrode, and controls (n = 4) underwent sham needle placement. Two animals underwent S3 dorsal rhizotomy to demonstrate that the observed results required afferent innervation. Voiding changes were demonstrated in 9 of 11 rabbits after stimulation. Most of the rabbits (7/9) exhibited a prolonged-dysfunctional voiding pattern with larger capacity (mean, 17 mL [SEM, ±8 mL]), longer intercontractile interval (227% [SEM, ±76%]) and duration (163% [SEM, ±20%]), and increased postvoid residual (24 mL [SEM, ±6 mL]). The remaining dysfunctional rabbits (2/9) exhibited an overactive-dysfunctional voiding pattern with lower capacity (-26 mL [SEM, ±6 mL]), shortened intercontractile interval (16% [SEM, ±9%]) and duration (56% [SEM, ±30%]), and decreased postvoid residual (-27 mL [SEM, ±6 mL]). Nonresponder rabbits (2/11) were relatively unchanged in their micturition cycles after stimulation. Rhizotomy animals were acontractile and filled until overflow incontinence occurred. Using noxious electrical stimulation of the pelvic musculature, we were able to produce an animal model of pelvic floor dysfunction in most rabbits as hallmarked by a larger bladder capacity, an increased intercontractile interval, and prolonged contraction duration.

  15. Pelvic floor dysfunction, and effects of pregnancy and mode of delivery on pelvic floor

    Directory of Open Access Journals (Sweden)

    Murat Bozkurt

    2014-12-01

    Full Text Available Pelvic floor dysfunction (PFD, although seems to be simple, is a complex process that develops secondary to multifactorial factors. The incidence of PFD is increasing with increasing life expectancy. PFD is a term that refers to a broad range of clinical scenarios, including lower urinary tract excretory and defecation disorders, such as urinary and anal incontinence, overactive bladder, and pelvic organ prolapse, as well as sexual disorders. It is a financial burden on the health care system and disrupts women's quality of life. Strategies applied to decrease PFD are focused on the course of pregnancy, mode and management of delivery, and pelvic exercise methods. Many studies in the literature define traumatic birth, usage of forceps, length of the second stage of delivery, and sphincter damage as modifiable risk factors for PFD. Maternal age, fetal position, and fetal head circumference are nonmodifiable risk factors. Although numerous studies show that vaginal delivery affects pelvic floor structures and their functions in a negative way, there is not enough scientific evidence to recommend elective cesarean delivery in order to prevent development of PFD. PFD is a heterogeneous pathological condition, and the effects of pregnancy, vaginal delivery, cesarean delivery, and possible risk factors of PFD may be different from each other. Observational studies have identified certain obstetrical exposures as risk factors for pelvic floor disorders. These factors often coexist; therefore, the isolated effects of these variables on the pelvic floor are difficult to study. The routine use of episiotomy for many years in order to prevent PFD is not recommended anymore; episiotomy should be used in selected cases, and the mediolateral procedures should be used if needed.

    Provide guidelines for clinical practice concerning postpartum rehabilitation. Systematically review of the literature concerning postpartum pelvic floor muscle training and abdominal rehabilitation. Pelvic-floor rehabilitation using pelvic floor muscle contraction exercises is recommended to treat persistent urinary incontinence at 3 months postpartum (grade A), regardless of the type of incontinence. At least 3 guided sessions with a therapist is recommended, associated with pelvic floor muscle exercises at home. This postpartum rehabilitation improves short-term urinary incontinence (1 year) but not long-term (6-12 years). Early pelvic-floor rehabilitation (within 2 months following childbirth) is not recommended (grade C). Postpartum pelvic-floor rehabilitation in women presenting with anal incontinence, is associated with a lower prevalence of anal incontinence symptoms in short-term (1 year) (EL3) but not long-term (6 and 12) (EL3). Postpartum pelvic-floor rehabilitation is recommended to treat anal incontinence (grade C) but results are not maintained in medium or long term. No randomized trials have evaluated the pelvic-floor rehabilitation in asymptomatic women in order to prevent urinary or anal incontinence in medium or long term. It is therefore not recommended (expert consensus). Rehabilitation supervised by a therapist (physiotherapist or midwife) is not associated with better results than simple advice for voluntary contraction of the pelvic floor muscles to prevent/correct, in short term (6 months), a persistent prolapse 6 weeks postpartum (EL2), whether or not with a levator ani avulsion (EL3). Postpartum pelvic-floor rehabilitation is not associated with a decrease in the prevalence of dyspareunia at 1-year follow-up (EL3). Postpartum pelvic-floor rehabilitation guided by a therapist is therefore not recommended to treat or prevent prolapse (grade C) or dyspareunia (grade C). No randomized trials have evaluated the effect of pelvic

  17. Recognition and Management of Nonrelaxing Pelvic Floor Dysfunction

    Faubion, Stephanie S.; Shuster, Lynne T.; Bharucha, Adil E.

    2012-01-01

    Nonrelaxing pelvic floor dysfunction is not widely recognized. Unlike in pelvic floor disorders caused by relaxed muscles (eg, pelvic organ prolapse or urinary incontinence, both of which often are identified readily), women affected by nonrelaxing pelvic floor dysfunction may present with a broad range of nonspecific symptoms. These may include pain and problems with defecation, urination, and sexual function, which require relaxation and coordination of pelvic floor muscles and urinary and anal sphincters. These symptoms may adversely affect quality of life. Focus on the global symptom complex, rather than the individual symptoms, may help the clinician identify the condition. The primary care provider is in a position to intervene early, efficiently, and effectively by (1) recognizing the range of symptoms that might suggest nonrelaxing pelvic floor dysfunction, (2) educating patients, (3) performing selective tests when needed to confirm the diagnosis, and (4) providing early referral for physical therapy.

    renovating housing. In Denmark, there are about 1 million dwellings in multi-storey housing. About half of the dwellings are built with timber floors, and the other half with wooden floors on concrete slabs, either in-situ cast or prefabricated hollow-core elements. In a project including mapping of sound...... insulation in the Danish housing stock and investigation of improvement possibilities, a pilot laboratory study of wooden floors on concrete was carried out. The laboratory study included impact sound improvement measurements of full-scale samples (10 m2) fulfilling the conditions in EN ISO 10140....... The measurements indicated up to about 8 dB improvement potential compared to floor constructions typical before the latest change of regulations, namely wooden floors on joists on PE wedges or similar. In addition, tests of small-scale samples (1 m2) – unsuitable for type testing – were performed to provide...

    The Strategic Petroleum Reserve (SPR) contains the largest supply is the largest stockpile of government-owned emergency crude oil in the world. The oil is stored in multiple salt caverns spread over four sites in Louisiana and Texas. Cavern infrastructure near the bottom of the cavern can be damaged from vertical floor movement. This report presents a comprehensive history of floor movements in each cavern. Most of the cavern floor rise rates ranged from 0.5-3.5 ft/yr, however, there were several caverns with much higher rise rates. BH103, BM106, and BH105 had the three highest rise rates. Information from this report will be used to better predict future vertical floor movements and optimally place cavern infrastructure. The reasons for floor rise are not entirely understood and should be investigated.

    Pelvic floor dysfunction after delivery is quite common. New mothers deserve to receive targeted care for pelvic floor dysfunction, but how should women who are at risk be identified and selected for treatment? This study investigated risk factors and puerperal health-seeking behaviours to develop a restrictive patient selection model for postpartum pelvic floor dysfunction assessment. This prospective observational study involved women who were at ≥32 weeks gestational age when they delivered in a tertiary referral maternity hospital in Milan, Italy, between July and December 2014. Eligible women were scheduled for a 3-month postnatal pelvic floor clinic. The adherence rate to the pelvic floor clinic and the prevalence of pelvic floor dysfunctions at 3 months postpartum were recorded. Univariable and logistic multivariable analyses were performed to select risk factors for pelvic floor dysfunctions. Risk factors were then tested for sensitivity and specificity for 3-month postpartum pelvic floor dysfunctions. Of 1606 eligible women, 1293 (80.5%) were included in the analysis; 685 puerperal women (53.0%) adhered to the 3-month postnatal pelvic floor clinic; pelvic floor dysfunctions were detected in 238 women (34.7%). Four elements emerged as risk factors: symptoms before pregnancy (OR 1.72, 95% CI 1.15-2.56; p=0.008), symptoms during pregnancy (OR 2.13, 95% CI 1.49-3.06; p<0.0001), vacuum extractor use (OR 1.62, 95% CI 1.04-2.54; p=0.034), and severe perineal tears (OR 19.45, 95% CI 2.42-156.15; p=0.005). The combined sensitivity and specificity for the 4 risk factors were 82% and 39%, respectively. Internal risk factors analysis offers the potential to efficiently restrict patient selection for follow-up. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    To calculate the prevalence of pelvic floor tenderness in the population of women with pelvic pain and to determine its implications for symptoms of pelvic pain. We conducted a retrospective review of patients with pelvic pain at a tertiary referral centre. Pelvic floor tenderness was defined as levator ani tenderness on at least one side during single digit pelvic examination. The prevalence of pelvic floor tenderness in this cohort of women with pelvic pain was compared with the prevalence in a cohort of women without pain attending a gynaecology clinic. In the women with pelvic pain, multiple regression was performed to determine which variables were independently associated with pelvic floor tenderness. The prevalence of pelvic floor tenderness was 40% (75/189) in the cohort with pelvic pain, significantly greater than the prevalence of 13% (4/32) in the cohort without pain (OR 4.61; 95% CI 1.55 to 13.7, P = 0.005). On multiple logistic regression, superficial dyspareunia (OR 4.45; 95% CI 1.86 to 10.7, P = 0.001), abdominal wall pain (OR 4.04; 95% CI 1.44 to 11.3, P = 0.005), and bladder base tenderness (OR 4.65; 95% CI 1.87 to 11.6, P = 0.001) were independently associated with pelvic floor tenderness. Pelvic floor tenderness was similarly present in women with or without underlying endometriosis. Pelvic floor tenderness is common in women with pelvic pain, with or without endometriosis, and is a contributor to superficial dyspareunia. Pelvic floor tenderness was also associated with abdominal wall pain and bladder base tenderness, suggesting that nervous system sensitization is involved in the etiology of pelvic floor tenderness.

    Conclusion: Persistent nursing intervention for pregnant/postpartum women helped to shorten the second stage of labour and contributed to the recovery of postpartum pelvic floor myodynamia. The influence of this intervention on the delivery mode, and rates of episiotomy and perineal laceration remains unknown. Medical staff should strengthen health education programmes that involve pelvic floor functional rehabilitation.

    Defaecatory MRI allows multicompartmental assessment of defaecatory dysfunction but is often inaccessible. Integrated total pelvic floor ultrasound (transperineal, transvaginal, endoanal) may provide a cheap, portable alternative. The accuracy of total pelvic floor ultrasound for anatomical abnormalities when compared with defaecatory MRI was assessed. The dynamic images from 68 females who had undergone integrated total pelvic floor ultrasound and defaecatory MRI between 2009 and 2015 were blindly reviewed. The following were recorded: rectocoele, enterocoele, intussusception and cystocoele. There were 26 rectocoeles on MRI (49 rectocoeles on ultrasound), 24 rectocoeles with intussusception on MRI (19 rectocoeles on ultrasound), 23 enterocoeles on MRI (24 enterocoeles on ultrasound) and 49 cystocoeles on MRI (35 cystocoeles on ultrasound). Sensitivity and specificity of total pelvic floor ultrasound were 81% and 33% for rectocoele, 60% and 91% for intussusception, 65% and 80% for enterocoele and 65% and 84% for cystocoele when compared with defaecatory MRI. This gave a negative-predictive value and positive-predictive value of 74% and 43% for rectocoele, 80% and 79% for intussusception, 82% and 63% for enterocoele and 48% and 91% for cystocoele. Integrated total pelvic floor ultrasound may serve as a screening tool for pelvic floor defaecatory dysfunction; when normal, defaecatory MRI can be avoided, as rectocoele, intussusception and enterocoele are unlikely to be present. Advances in knowledge: This is the first study to compare integrated total pelvic floor ultrasound with defaecatory MRI. The results support the use of integrated total pelvic floor ultrasound as a screening tool for defaecatory dysfunction.

    The aim of this study was to investigate the effects of pelvic floor muscle exercise during pregnancy and the postpartum period on pelvic floor muscle activity and voiding functions. Pregnant women (n = 60) were randomly assigned into two groups (Training [n = 30] and Control [n = 30]) using a computer-based system. Pelvic floor muscle strength was measured using a perineometry device. Urinary symptoms were measured using the Urinary Distress Inventory (UDI-6), Incontinence Impact Questionnaire (IIQ-7), and the Overactive Bladder Questionnaire (OAB-q). Voiding functions were measured using uroflowmetry and 3-day voiding diaries. Measurements were obtained at week 28, weeks 36-38 of pregnancy, and postpartum weeks 6-8. Pelvic floor muscle strength significantly decreased during the pregnancy (P pelvic floor muscle strength improvement was significantly higher in the Training group compared to the Control group (P  0.05). However, UDI-6, coping, concern, and total scores of OAB-q were significantly decreased during weeks 36-38 of pregnancy in the Control group (P pelvic floor muscle strength, urinary symptoms, quality of life, and voiding functions.

    Introduction and Hypothesis We evaluated the associations between pelvic floor muscle strength and tone with sexual activity and sexual function in women with pelvic floor disorders. Methods This was a secondary analysis of a multicenter study of women with pelvic floor disorders from the US and UK performed to validate the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR). Participants were surveyed about whether they were sexually active and completed the PISQ-IR and Female Sexual Function Index (FSFI) questionnaires to assess sexual function. Physical exams included assessment of pelvic floor strength by the Oxford Grading Scale, and assessment of pelvic floor tone per ICS guidelines. Results The cohort of 585 women was middle aged (mean age 54.9 +/−12.1) with 395 (67.5%) reporting sexual activity. Women with a strong pelvic floor (n=275) were more likely to report sexual activity than women with weak strength (n=280) (75.3 vs. 61.8%, ppelvic floor tone was not associated with sexual activity (68.8 vs. 60.2%, normal vs. hypoactive, p=0.08). After multivariable analysis, a strong pelvic floor remained predictive of sexual activity (OR 1.89, CI 1.18–3.03, ppelvic floor was associated with higher scores on the PISQ-IR domain of condition impact (Parameter Estimate 0.20+/−0.09, P=0.04), and FSFI orgasm domain (PE 0.51+/−0.17, P=0.004). Conclusion A strong pelvic floor is associated with higher rates of sexual activity as well as higher sexual function scores on the condition impact domain of the PISQ-IR and orgasm domain of the FSFI.

    To compare the functional and anatomical outcomes after a 0.2 µg/day fluocinolone acetonide (FAc) implant between vitrectomized and nonvitrectomized eyes with chronic diabetic macular edema (DME). This is a retrospective, comparative analysis of 43 eyes with chronic DME. All eyes were treated with a single 0.2 µg/day FAc implant and followed up for a mean period of 8.5 months (median, 6.0 months; range, 1-21 months). The patients with a 0.2 µg/day FAc implant were divided into 2 groups: 24 eyes which had undergone pars plana vitrectomy prior to 0.2 µg/day FAc (group 1) and 19 eyes which had not been vitrectomized (group 2). Outcome measures included mean changes in best corrected visual acuity (BCVA) in Early Treatment Diabetic Retinopathy Study letters, central subfield foveal thickness (CSFT), and intraocular pressure (IOP), and were measured prior to administration of the 0.2 µg FAc implant, in the first week, at month 1, and quarterly thereafter. Following the 0.2 μg/day FAc implant, the mean change in BCVA at the last observation point, from baseline, was +16.9 ± 3.39 (mean ± SE) letters (p ≤ 0.001) in group 1 and +8.2 ± 4.62 letters (p = 0.092) in group 2. From baseline, a gain of ≥15 letters was achieved in 37.5 and 36.8% of the eyes in group 1 and group 2, respectively. Additionally, an improvement in vision ≥20/40 in 29.2% of group 1 and 15.8% of group 2 was observed. The mean change in CSFT was -217.7 ± 40.8 µm and -155.6 ± 43.4 µm in group 1 and group 2, respectively. The mean change in IOP was +1.6 ± 0.7 mm Hg in group 1 and +0.8 ± 1.3 mm Hg in group 2, relative to baseline. At the last observation point, there were no significant differences between groups 1 and 2 (p > 0.05) in terms of their changes in BCVA, CSFT, and IOP. The results from the real-life practice study demonstrate that the 0.2 μg/day FAc implant is effective and well tolerated in vitrectomized and nonvitrectomized eyes of patients with chronic DME.

    2018-01-01

    Pelvic floor damage can occur during pregnancy, during childbirth or post-partum, and may be expressed by symptoms such as urinary incontinence, fecal and gas incontinence, sexual dysfunction, pelvic organ prolapse and chronic pelvic pain. Some of the symptoms, which manifest later in a woman's life, will go unrecognized in the immediate postpartum period. Most women do not mention their general health, unless specifically asked. Physiotherapists, who are adept with the anatomy of the musculoskeletal system and the ability to diagnose unique differences, can aid in the diagnosis and treatment of postpartum pelvic floor problems. Monitoring, pelvic floor physiotherapy and exercise can be effective both in treatment and prevention of functional disorders of the pelvic floor. In this article, we will discuss pelvic floor problems and their appearance throughout pregnancy and childbirth, and the means of treatment from the physiotherapist's perspective. We raise the question as to whether all postpartum women could benefit from a training program of pelvic floor muscles. Pelvic floor physiotherapy is included in the health basket in Israel, but is not broadly utilized. Wider use could be adopted, particularly in light of the latest research evidence.

  11. Floor-Fractured Craters through Machine Learning Methods

    2015-12-01

    Floor-fractured craters are impact craters that have undergone post impact deformations. They are characterized by shallow floors with a plate-like or convex appearance, wide floor moats, and radial, concentric, and polygonal floor-fractures. While the origin of these deformations has long been debated, it is now generally accepted that they are the result of the emplacement of shallow magmatic intrusions below their floor. These craters thus constitute an efficient tool to probe the importance of intrusive magmatism from the lunar surface. The most recent catalog of lunar-floor fractured craters references about 200 of them, mainly located around the lunar maria Herein, we will discuss the possibility of using machine learning algorithms to try to detect new floor-fractured craters on the Moon among the 60000 craters referenced in the most recent catalogs. In particular, we will use the gravity field provided by the Gravity Recovery and Interior Laboratory (GRAIL) mission, and the topographic dataset obtained from the Lunar Orbiter Laser Altimeter (LOLA) instrument to design a set of representative features for each crater. We will then discuss the possibility to design a binary supervised classifier, based on these features, to discriminate between the presence or absence of crater-centered intrusion below a specific crater. First predictions from different classifier in terms of their accuracy and uncertainty will be presented.

    Projections of energy demands for the year 2000 show that nuclear power will likely be one of our energy sources. But the benefits of nuclear power must be balanced against the drawbacks of its by-product: high-level wastes. While it may become possible to completely destroy or eliminate these wastes, it is at least equally possible that we may have to dispose of them on earth in such a way as to assure their isolation from man for periods of the order of a million years. Undersea regions in the middle of tectonic plates and in the approximate center of major current gyres offer some conceptual promise for waste disposal because of their geologic stability and comparatively low organic productivity. The advantages of this concept and the types of detailed information needed for its accurate assessment are discussed. The technical feasibility of permanent disposal beneath the deep sea floor cannot be accurately assessed with present knowledge, and there is a need for a thorough study of the types and rates of processes that affect this part of the earth's surface. Basic oceanographic research aimed at understanding these processes is yielding answers that apply to this societal need. (U.S.)

    We hypothesised that the pressure on the cervix increases with advancing gestation and it may lead to a cervical shortening and cause preterm labour in women with weak pelvic floor muscles. The aim of this prospective study was to measure vaginal resting pressure and pelvic floor muscle strength in the first trimester of pregnancy and to investigate their effects on labour. A study was conducted on the pregnant women with a low risk for preterm birth. The pelvic floor muscle strength and vaginal resting pressure were assessed in 320 pregnant women at their first trimester with a vaginal pressure measurement device. Fifty-two pregnant women were hospitalised for tocolytic therapy because of spontaneous preterm labour. Thirty-two of them (10.2%) had a preterm delivery despite the tocolytic therapy. Both the vaginal resting pressure (p = .009, 95%CI: 0.8; 5.9) and the pelvic floor muscle strength (p = .01, 95%CI: 3.5; 13.1) were significantly lower in the women with a preterm labour. Impact statement What is already known on this subject? The pelvic floor muscles have an essential role in continence and provide support to the pelvic organs. They also have an impact on labour. The pelvic floor muscles should distend to allow the passage of the foetus during labour. The rotation and flexion of the foetal head is due to the pelvic floor resistance. The effect of a vaginal birth on the pelvic floor's function is readily understood. On the other hand, the effect of the pelvic floor muscle function on labour is still controversial. What do the results of this study add? This prospective study showed that there is a negative association between the pelvic floor muscle strength and preterm labour. This is the first clinical study indicating that weak pelvic floor muscles may cause a preterm labour. What are the implications of these findings for clinical practice and/or further research? Pelvic floor physical therapy may be an alternative preventive strategy to reduce

    Vulvar pain affects up to 20% of women at some point in their lives, and most women with vulvar pain have associated pelvic floor impairments. Pelvic floor dysfunction is associated with significant functional limitations in women by causing painful intercourse and urinary, bowel, and sexual dysfunction. A quick screening of the pelvic floor muscles can be performed in the gynecology office and should be used when patients report symptoms of pelvic pain. It is now known the vulvar pain syndromes are heterogeneous in origin; therefore, successful treatment plans are multimodal and include physical therapy. Copyright © 2017 Elsevier Inc.

    A 53-year-old patient presented with recurrent epicleritis of the right eye for 6 months and progressive diplopia. He had a past history of orbital floor repair over 30 years. A CT scan showed a radiodense migrated orbital floor sheet implant in the maxillary sinus causing obstruction of the maxillary sinus ostium, secondary maxillary sinusitis with retrobulbar involvement. The silastic orbital implant was removed via a Caldwell Luc approach and resolution of the patient's symptoms and signs quickly ensued. We discuss this late complication of orbital floor fracture repair presenting initially as recurrent episcleritis and maxillary sinusitis with intraorbital extension. This report also emphasizes the importance of history taking.

    Several urogynecologic syndromes are associated with the clinical finding of a short, painful, tender and weak pelvic floor and a variety of connective tissue abnormalities. Techniques for rehabilitation include the avoidance of perpetuating factors, rehabilitation of extrapelvic musculoskeletal abnormalities, the use of manual techniques and needling to promote resolution of connective tissue problems, closure of any diastasis recti, and transvaginal/transrectal manual release of muscular trigger points and contractures. Therapy can be facilitated by pudendal or epidural nerve block. Patients contribute to their success through home maintenance programs.

    In a prospective study of 83 women, two different physiotherapy methods for strengthening the pelvic floor muscles after childbirth were evaluated. The training program was carried out by the patients at home for 12 weeks, starting 8 weeks after spontaneous uneventful delivery. Forty-two women did pelvic floor exercises in accordance with the method presented by Kegel. Forty-one women used standard vaginal cones with weights increasing in 10 g stages from 20 to 100 g, to be retained in the vagina both when standing erect and moving. Pelvic floor muscle strength, defined as the weight in grams of the heaviest cone that could be retained in the vagina, was recorded before and after the 12-week training period. Training with vaginal cones produced significantly better pelvic floor muscle strength than did exercise without cones.

    Plessis, T.A. du; Badenhorst, F.

    1988-01-01

    Gamma radiation presents a unique method of transforming highly plasticized PVC floor tiles, manufactured at high speed through injection moulding, into a high quality floor covering at a cost at least 30% less than similarly rated rubber tiles. A specially formulated PVC compound was developed in collaboration with a leading manufacturer of floor tiles. These tiles are gamma crosslinked in its shipping cartons to form a dimensionally stable product which is highly fire resistant and inert to most chemicals and solvents. These crosslinked tiles are more flexible than the highly filled conventional PVC floor tiles, scratch resistant and have a longer lifespan and increased colour fastness. These tiles are also less expensive to install than conventional rubber tiles. (author)

    This test program was initiated because a need existed at the Kennedy Space Center (KSC) to have this information readily available to the engineer who must make the choice of which electrostatic safe floor to use in a specific application. The information, however, should be of value throughout both the government and private industry in the selection of a floor covering material. Included are the test results of 18 floor covering materials which by test evaluation at KSC are considered electrostatically safe. Tests were done and/or the data compiled in the following areas: electrostatics, flammability, hypergolic compatibility, outgassing, floor type, material thickness, and available colors. Each section contains the test method used to gather the data and the test results.

    To understand the function of the pelvic floor muscles (PFM) at different ages in healthy women and in puerperal women with pelvic floor dysfunctions (PFD) and to ascertain whether there are differences among them. A descriptive cross-sectional study was conducted between June 2014 and September 2016 and included 177 women, 70 of whom had no symptoms of PFD, 53 primiparous mothers in late postpartum and 54 with PFD. The function of the PFM was measured through vaginal palpation (quality of the contraction); manometry (force); dynamometer (tone, strength, and response to stretching), and surface electromyography (neuromuscular activity and resistance). The healthy women showed superior values for PFM tone, maximum strength, neuromuscular activity and resistance than the puerperal mothers and the women with PFD (P.05). The muscle function of the healthy women did not vary significantly with age, except in the case of tone, which was lower in the women older than 46 years (P=.004). Age and births decrease the baseline tone of the PFM in healthy women. Therefore, lower strength, resistance and neuromuscular activity appear to be the main difference between the PFM of women with PFD and the PFM of healthy women. Copyright © 2016 AEU.

    Successful management of dysfunctional voiding in children hinges on retraining inappropriate pelvic floor muscle recruitment. Recently dynamic pelvic floor muscle activity was visualized in adults using transabdominal ultrasound. We evaluated transabdominal ultrasound for visualizing and measuring pelvic floor muscle activity in normative children. A total of 21 volunteers, including 10 boys and 11 girls 7 to 16 years old (mean age 11.6) who were free of bladder disorders consented to participate in the study. Subjects were screened and demonstrated normative bladder emptying before being imaged while supine and standing using a sagittal curved linear array 2 to 5 MHz transducer over the suprapubic region. After pelvic floor muscle contraction was explained 4 parameters were measured 3 times each, including the direction of movement/displacement from freeze-frame ultrasound images, and endurance and coordination from ultrasound movie loops. The methodology for digitizing movie data were developed, tested and found to be reliable. New variables of endurance as a percent of maximum coordination amplitude and coordination as the amplitude between maximum and minimum effort were created. Overall 66% and 71% of subjects demonstrated anterior displacement of the pelvic floor during voluntary contraction while lying and standing, respectively, with no significant difference in lying vs standing. However, coordination displacement was greater while lying than standing. During 20-second contractions pelvic floor muscle activity attained peak amplitude at 5.5 seconds, followed by a marked decay with 1 or more cycles of muscular re-recruitment. It was observed that fatigue led to repeat recruitment of the rectus and oblique abdominal muscles. In children free of voiding dysfunction pelvic floor displacement and coordination are highly variable. Noninvasive ultrasound of the pelvic floor provided visual assessment of muscular activity, a biofeedback component for the patient

    Kuo, Tricia L C; Ng, L G; Chapple, Christopher R

    2015-07-01

    Pelvic floor disorders can present with lower urinary tract symptoms, bowel, sexual dysfunction, and/or pain. Symptoms of pelvic muscle spasm (nonrelaxing pelvic floor or hypertonicity) vary and can be difficult to recognize. This makes diagnosis and management of these disorders challenging. In this article, we review the current evidence on pelvic floor spasm and its association with voiding dysfunction. To distinguish between the different causes of voiding dysfunction, a video urodynamics study and/or electromyography is often required. Conservative measures include patient education, behavioral modifications, lifestyle changes, and pelvic floor rehabilitation/physical therapy. Disease-specific pelvic pain and pain from pelvic floor spasm needs to be differentiated and treated specifically. Trigger point massage and injections relieves pain in some patients. Botulinum toxin A, sacral neuromodulation, and acupuncture has been reported in the management of patients with refractory symptoms. Pelvic floor spasm and associated voiding problems are heterogeneous in their pathogenesis and are therefore often underrecognized and undertreated; it is therefore essential that a therapeutic strategy needs to be personalized to the individual patient's requirements. Therefore, careful evaluation and assessment of individuals using a multidisciplinary team approach including a trained physical therapist/nurse clinician is essential in the management of these patients.

  15. Role of pelvic floor in lower urinary tract function.

    Chermansky, Christopher J; Moalli, Pamela A

    2016-10-01

    The pelvic floor plays an integral part in lower urinary tract storage and evacuation. Normal urine storage necessitates that continence be maintained with normal urethral closure and urethral support. The endopelvic fascia of the anterior vaginal wall, its connections to the arcus tendineous fascia pelvis (ATFP), and the medial portion of the levator ani muscles must remain intact to provide normal urethral support. Thus, normal pelvic floor function is required for urine storage. Normal urine evacuation involves a series of coordinated events, the first of which involves complete relaxation of the external urethral sphincter and levator ani muscles. Acquired dysfunction of these muscles will initially result in sensory urgency and detrusor overactivity; however, with time the acquired voiding dysfunction can result in intermittent urine flow and incomplete bladder emptying, progressing to urinary retention in severe cases. This review will start with a discussion of normal pelvic floor anatomy and function. Next various injuries to the pelvic floor will be reviewed. The dysfunctional pelvic floor will be covered subsequently, with a focus on levator ani spasticity and stress urinary incontinence (SUI). Finally, future research directions of the interaction between the pelvic floor and lower urinary tract function will be discussed. Copyright © 2015 Elsevier B.V. All rights reserved.

    2008-01-01

    Endoscopic repair of orbital blow-out fractures could become a predictable and efficient treatment alternative to traditional methods. However, maxillary sinus endoscopy provides a complex and disorienting view of the orbital floor. To be a useful and consistent technique for providing access to the orbital floor, specific knowledge of maxillary endoscopic anatomy is required. The purpose of the study was to provide an anatomic description of the orbital floor via the endoscopic approach. Objectives include defining consistent landmarks for use in endoscopic repair of orbital floor fractures. Using 0- and 30-degree rigid endoscopes, 6 fresh cadavers (12 maxillary sinuses) were examined via a standard Caldwell-Luc approach. Computed tomographic scans, plastic molds, and digital images were used to compare observable averages within bony anatomy. Potential bony landmarks were correlated with soft-tissue anatomy in fresh specimens. The maxillary ostium, orbital floor, and lateral ethmoid air cells were visualized, and their structures were described. Observations were made in relation to the anatomy of the orbital floor and maxillary sinus, including fracture pattern and force transmission pathways. An "orbitomaxillary" sinus bony thickening was identified and described for the first time. This study provides the basis for further refinement of surgical technique and opens the door for future clinical trials using endoscopic repair.

    This paper describes the generation of floor time histories and corresponding floor response spectrums at various locations in reactor containment building (RCB) for 500 MWe Prototype Fast Breeder Reactor (PFBR). The RCB and its internal structures are modeled with equivalent 3D-beam elements (stick model), which have got the essential global stiffness and inertial properties of the corresponding building. The main aspect in the simulation of beam model is derivation of equivalent cross sectional properties such as bending, torsional and shear rigidities including shear centers. These properties have been obtained through 3D plate/shell element models with appropriate kinematic constraints, for the zones between floors of corresponding buildings. The stick model includes a set of springs and dampers to simulate soil effects, on which base raft and various sticks are mounted. The soil stiffness and damping values are derived based on equations given in ASCE-98. Time history analysis has been done using three uncorrelated time histories, which are derived from the site dependent design response spectra. Floor time histories (FTH) are extracted at important locations from which the corresponding floor response spectrums (FRS) have been generated for various damping values. Peak broadening of the response spectrums has been done according ASCE criteria. Floor response spectrum corresponds to reactor assembly support shows amplification 2.5 for SSE and 3 for OBE. CASTEM 3M is used for seismic analysis and generation of FRS. (author)

    Chronic prostatitis/chronic pelvic pain syndrome is a common condition that often requires multimodal therapy. Patients with chronic pelvic pain syndrome have a high incidence of pelvic floor spasm, which can be treated with pelvic floor physical therapy. However, this is a specialized skill. We compared outcomes of pelvic floor physical therapy as part of multimodal therapy in patients with chronic pelvic pain syndrome between those treated at our institution and elsewhere. We identified patients from our chronic pelvic pain syndrome registry with pelvic floor spasm who were seen between 2010 and 2014 for more than 1 visit. Patient phenotype was assessed with the UPOINT system and symptom severity was determined by the National Institutes of Health CPSI. A 6-point decrease in CPSI was used to define patient improvement. A total of 82 patients fit the study criteria. Mean age was 41.6 years (range 19 to 75) and median symptom duration was 24 months (range 3 to 240). Mean CPSI was 26.8 (range 10 to 41), the median number of positive UPOINT domains was 3 (range 1 to 6) and 27 patients (32.9%) were treated locally. At followup 9 patients had refused pelvic floor physical therapy, and 24 and 48 had undergone pelvic floor physical therapy elsewhere and at CCF, respectively. The mean change in CPSI was 1.11 ± 4.1 in patients who refused, -3.46 ± 6.7 in those treated elsewhere and -11.3 ± 7.0 in those treated at CCF (p physical therapy at CCF (OR 4.23, p = 0.002) and symptom duration (OR 0.52, p = 0.03) predicted improvement. Pelvic floor physical therapy can be effective for chronic pelvic pain syndrome in patients with pelvic floor spasm. However, the outcome depends on specialty training and experience of therapists.

    Full Text Available Introduction: Panoramic radiograph is frequently prescribed by dentists for implant planning and, hence, accurate assessment of anatomical structures in panoramic radiograph is of utmost importance. Aims: The aim of the present study is to know the accuracy of panoramic radiograph in assessment of relationship between maxillary sinus floor and posterior teeth roots, and the distance from alveolar crest to nasal floor by comparing it with that of cone-beam computed tomographic (CBCT image. Materials and Methods: Panoramic and CBCT images of 30 patients were analyzed. The topographic relationship of each root of posterior teeth to the maxillary sinus floor was evaluated and classified into three classes. The distance from the peak point on maxillary alveolar crest to nasal floor was measured in panoramic radiograph as well as in CBCT image. All the measurements were made by built-in measurement tools. Results: Class 1 roots in panoramic radiograph showed high agreement (86% with CBCT image, followed by class 0 (76%. There was a significant difference in the measurements of alveolar bone height (ABH in the nasal floor region with a P value of 0.018. Conclusion: Panoramic radiograph is reliable in assessment of nasal floor and maxillary sinus, provided position of the patient, distortion, and the inherent magnification factor are taken into consideration.

    Chronic pelvic pain is a prevalent and debilitating condition with a wide range of etiologies. An estimated 30% to 70% of chronic pelvic cases involve musculoskeletal component pain including high-tone pelvic floor dysfunction (HTPFD). Pelvic floor physical therapy has been shown to be a beneficial treatment for HTPFD, yet many patients do not have access to this treatment. The objective of this study was to identify the barriers preventing patients from following through with the first-line management, physical therapy. Participants with a diagnosis of HTPFD (n = 154) were identified from the list of referrals sent from the obstetrics and gynecology department to an affiliated PFPT center. Participants were contacted and asked to complete a phone survey addressing demographics and perceived barriers to care. Responses were collected in REDCap. Univariate and bivariate analyses were performed using a statistical analysis software. Seventy surveys were completed. The top barriers identified by participants were financial constraints (51.4%), perceived lack of utility (37.1%), time constraints (30.0%), and travel issues (18.6%); 84.4% of participants had 1 or more comorbid pain condition. Whereas 51.4% expressed some level of anxiety regarding the PFPT option, only 9.6% of participants did not start treatment because of fear of treatment. The majority of treatment barriers identified were concrete restraints, with insurance noncoverage and time constraints being the top issues. A fair number of participants expressed anxiety about the treatment or felt they received unclear explanations of the treatment. These are areas in which providers can potentially alleviate some barriers to care.

    Objective: To analyze re-treatments of recurrence after the pelvic floor repair surgery. Methods: The protocol and the effect of re-treatments were investigated by reviewing and analyzing the clinical data of 81 recurrent patients (grade Ⅱ and above), who had received the pelvic floor repair surgery from January 2011 to January 2016. Pelvic organ prolapse quantitation system (POP-Q) and two questionnaires about quality of life [pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire short form (PFIQ-7)] were used to evaluate objective and subjective efficacy, respectively. Results: Among 81 recurrent patients who were followed up for a median of 35 months (10- 69 months), 78 cases (with prolapse up to grade Ⅲ or Ⅳ) were treated by surgical operation with both objective cure rate and subjective satisfaction being 100% (78/78); 3 cases (with grade Ⅱ prolapse) were treated by pelvic floor electrical stimulation biofeedback, and 1 case among the three cases had the vaginal foreign body sensation, the subjective satisfaction was 2/3. The methods of surgical operation for the 78 recurrent patients included: total pelvic floor reconstructive surgery (55 cases; 3 of which involve trachelectomy), anterior pelvic reconstructive surgery (2 cases), posterior pelvic reconstructive surgery (3 cases), Y-mesh sacral colpopexy (2 cases), colpocleisis (11 cases), vaginal hysterectomy combined posterior fornix forming (3 cases), and vaginal hysterectomy combined posterior pelvic reconstructive surgery(2 cases). Conclusion: The extent of recurrence, the recurrent site and complications must be carefully considered and evaluated for re-treatments of recurrence after pelvic floor repair surgery, and then an appropriately individualized re-treatment protocol could be designed for each of the patients.

    To analyze the proven mechanisms of action of pelvic rehabilitation in women presenting with urinary incontinence. Review of literature (PubMed, Embase, Cochrane Database) using following keywords: female; urinary incontinence; overactive bladder syndrome; stress urinary incontinence; bladder training; bladder diary; pelvic floor muscle training; pelvic floor rehabilitation; physiotherapy; cognitive therapies. Among 2906 articles (animal and anatomical studies have been excluded); 66 have been selected because they focused on the evaluation of the pathophysiological mechanisms of pelvic floor rehabilitation concerning female urinary incontinence. Studies on pelvic floor muscles training exercises showed a significant increase in the force of contraction of these muscles and it was correlated with improved scores of urinary incontinence and pad test (coefficient of correlation r ranged from 0.23 to 0.34) for women presenting with stress urinary incontinence. These studies have not observed an increase in the maximum urethral closure pressure (MUCP) or correction of urethral hypermobility related with the improvement of incontinence after rehabilitation sessions. Studies concerning pelvic floor stimulation observed an increase in the force of contraction of pelvic floor muscles after rehabilitation and a decrease in the intensity of detrusor contractions without changing the MUCP. There is very little data on the precise mechanisms of action of biofeedback and cognitive behavioral therapy. In studies that objectively evaluated the mechanisms of action of pelvic rehabilitation, it was observed that pelvic floor muscles voluntary exercises and electrostimulation resulted an increase in force of contraction of these muscles without changing the MUCP.

    Phase change materials (PCMs) can be used to shift the cooling or heating load from the peak period to the off-peak period. In this paper, a new double layer phase change material (PCM) floor is put forward. The two layers of PCM have different melting temperature. The system is used to store heat or cold energy in the off-peak period and release them in the peak period during heating or cooling. According to the numerical model built in this paper, the thermal performances of the floor are analyzed. The results show that the optimal melting temperatures of PCMs exist. The fluctuations of the floor surface temperatures and the heat fluxes will be reduced and the system still can provide a certain amount of heat or cold energy after the heat pump or chiller has been turned off for a long time. Compared to the floor without PCM, the energy released by the floor with PCM in peak period will be increased by 41.1% and 37.9% during heating and cooling when the heat of fusion of PCM is 150 kJ/kg. - Highlights: → A new double layer phase change material floor is put forward. → The system is used to store heat or cold energy in the off-peak period and release them in the peak period during heating or cooling. → The optimal melting temperatures of PCMs in the system exist. → The heat and cold energy released by the floor with PCM in peak period can be increased by 41.1% and 37.9%.

    Objective To assess prenatal counseling practices of obstetrical providers related to postpartum pelvic floor dysfunction at centers with integrated urogynecology services. Study Design A cross-sectional survey was distributed to obstetrical providers through urogynecology colleagues. The survey included questions about level of training as well as counseling practices related to common postpartum pelvic floor symptoms. All statistical tests were two sided, and P values <0.05 were considered statistically significant. Results One hundred ninety-two surveys were received; 19 respondents did not perform their own prenatal counseling and were excluded. Among the remaining 173 respondents, 94 (56.3%) of those who answered the question reported never discussing postpartum urinary incontinence, and 73.7% reported never discussing postpartum fecal incontinence during prenatal counseling. Obstetrics and gynecology residents were significantly less likely than attending physicians to report discussing various pelvic floor dysfunction topics in prenatal counseling. Among those who reported not counseling women regarding pelvic floor dysfunction, the most common reason cited was lack of time (39.9%) followed by lack of sufficient information (30.1%). Conclusion Prenatal counseling of pelvic floor dysfunction risk is lacking at all levels of obstetrical training. Limitations of time and information are the obstacles most often cited by providers.

    2015-02-01

    A significant reduction in hiatal area and anteroposterior diameter can be induced by pelvic floor muscle contraction, and this has been demonstrated using three-dimensional/four-dimensional (3D/4D) transperineal ultrasound (TPS) in a small group of women. Our objective was to correlate pelvic floor muscle contractility using digital assessment with the change in TPS hiatus measurements during maximum pelvic floor muscle contraction. Nulliparous pregnant women were recruited from the antenatal clinic. Pelvic floor muscle contractility was assessed by digital palpation using the validated Modified Oxford Scale (MOS). Subsequently, women underwent 3D/4D TPS. Measurements of the hiatal area and anteroposterior diameter were taken from the rendered ultrasound images at rest and at maximum contraction, and differences in measurements were expressed as percentages. Spearman's rank (ρ) was used to assess the correlation. Four hundred and fifty-nine assessments were performed, of which 268 were from women at around 36 weeks' gestation, and 191 were from women following delivery at 3 months postpartum. The overall correlation between MOS and TPS was found to be ρ = 0.47 for hiatal area (P biofeedback when training patients in pelvic floor muscle exercises. As TPS is non-intrusive, it may be the method of choice for some women. Copyright © 2014 ISUOG. Published by John Wiley & Sons Ltd.

    Full Text Available Introduction. Pelvic floor dysfunction syndromes present with voiding, sexual, and anorectal disturbances, which may be associated with one another, resulting in complex presentation. Thus, an integrated diagnosis and management approach may be required. Pelvic muscle rehabilitation (PMR is a noninvasive modality involving cognitive reeducation, modification, and retraining of the pelvic floor and associated musculature. We describe our standardized PMR protocol for the management of pelvic floor dysfunction syndromes. Pelvic Muscle Rehabilitation Program. The diagnostic assessment includes electromyography and manometry analyzed in 4 phases: (1 initial baseline phase; (2 rapid contraction phase; (3 tonic contraction and endurance phase; and (4 late baseline phase. This evaluation is performed at the onset of every session. PMR management consists of 6 possible therapeutic modalities, employed depending on the diagnostic evaluation: (1 down-training; (2 accessory muscle isolation; (3 discrimination training; (4 muscle strengthening; (5 endurance training; and (6 electrical stimulation. Eight to ten sessions are performed at one-week intervals with integration of home exercises and lifestyle modifications. Conclusions. The PMR protocol offers a standardized approach to diagnose and manage pelvic floor dysfunction syndromes with potential advantages over traditional biofeedback, involving additional interventions and a continuous pelvic floor assessment with management modifications over the clinical course.

  12. TOWARDS OBJECT DRIVEN FLOOR PLAN EXTRACTION FROM LASER POINT CLOUD

    Full Text Available During the last years, the demand for indoor models has increased for various purposes. As a provisional step to proceed towards higher dimensional indoor models, powerful and flexible floor plans can be utilised. Therefore, several methods have been proposed that provide automatically generated floor plans from laser point clouds. The prevailing methodology seeks to attain semantic enhancement of a model (e.g. the identification and labelling of its components built upon already reconstructed (a priori geometry. In contrast, this paper demonstrates preliminary research on the possibility to directly incorporate semantic knowledge, which is itself derived from the raw data during the extraction, into the geometric modelling process. In this regard, we propose a new method to automatically extract floor plans from raw point clouds. It is based on a hierarchical space partitioning of the data, integrated with primitive selection actuated by object detection. First, planar primitives corresponding to vertical architectural structures are extracted using M-estimator SAmple and Consensus (MSAC. The set of the resulting line segments are refined by a selection process through a novel door detection algorithm, considering optimization of prior information and fitness to the data. The selected lines are used as hyperlines to partition the space into enclosed areas. Finally, a floor plan is extracted from these partitions by Minimum Description Length (MDL hypothesis ranking. The algorithm is applied on a real mobile laser scanner dataset and the results are evaluated both in terms of door detection and consecutive floor plan extraction.

  13. Valorization of Municipal Waterworks Sludge to Produce Ceramic Floor Tiles

    2018-03-01

    Full Text Available In municipal waterworks large amounts of waste in the form of sludge have to be discarded. This investigation focuses on the processing of ceramic floor tiles incorporated with a municipal waterworks sludge. Four floor tile formulations containing up to 10 wt. % of the municipal waterworks sludge were prepared in order to replace the kaolin. The floor tile processing route consisted of dry powder granulation, uniaxial pressing, and firing between 1190 and 1250 °C using a fast-firing cycle (<60 min. The densification behavior and technological properties of the floor tile pieces as function of the sludge addition and firing temperature were determined. The development of the microstructure was followed by XRD and SEM/EDS. The results show that the replacement of kaolin with municipal waterworks sludge, in the range up to 10 wt. %, allows the production of ceramic floor tiles (group BIb and group BIIa, ISO 13006 Standard at lower firing temperatures. These results suggest a new possibility of valorization of municipal waterworks sludge in order to bring economic and environmental benefits.

    Floor heating systems are important components of nowadays home-automation setups. The control of a floor heating system is a nontrivial task and the present solutions essentially implement variants of a simple bang-bang controller that opens for a hot water circulation in a room if its current...... temperature is below the user defined target temperature, otherwise it closes for the heating in the room.

  18. Acoustics advances study of sea floor hydrothermal flow

    Science.gov (United States)

    Rona, Peter A.; Jackson, Darrell R.; Bemis, Karen G.; Jones, Christopher D.; Mitsuzawa, Kyohiko; Palmer, David R.; Silver, Deborah

    Sub-sea floor hydrothermal convection systems discharge as plumes from point sources and as seepage from the ocean bottom. The plumes originate as clear, 150-400°C solutions that vent from mineralized chimneys; precipitate dissolved metals as particles to form black or white smokers as they turbulently mix with ambient seawater; and buoyantly rise hundreds of meters to a level of neutral density where they spread laterally. The seepage discharges from networks of fractures at the rock-water interface as clear, diffuse flow, with lower temperatures, metal contents, and buoyancy than the smokers. The diffuse flow may be entrained upward into plumes, or laterally by prevailing currents in discrete layers within tens of meters of the sea floor. The role of these flow regimes in dispersing heat, chemicals, and biological material into the ocean from sub-sea floor hydrothermal convection systems is being studied on a global scale.

  19. Gait Analysis Using Floor Markers and Inertial Sensors

    Directory of Open Access Journals (Sweden)

    Young Soo Suh

    2012-02-01

    Full Text Available In this paper, a gait analysis system which estimates step length and foot angles is proposed. A measurement unit, which consists of a camera and inertial sensors, is installed on a shoe. When the foot touches the floor, markers are recognized by the camera to obtain the current position and attitude. A simple planar marker with 4,096 different codes is used. These markers printed on paper are placed on the floor. When the foot is moving off the floor, the position and attitude are estimated using an inertial navigation algorithm. For accurate estimation, a smoother is proposed, where vision information and inertial sensor data are combined. Through experiments, it is shown that the proposed system can both track foot motion and estimate step length.

  20. Floor response spectra of buildings with uncertain structural properties

    International Nuclear Information System (INIS)

    Chen, P.C.

    1975-01-01

    All Category I equipment, such as reactors, vessels, and major piping systems of nuclear power plants, is required to withstand earthquake loadings in order to minimize risk of seismic damage. The equipment is designed by using response spectra of the floor on which the equipment is mounted. The floor response spectra are constructed usually from the floor response time histories which are obtained through a deterministic dynamic analysis. This analysis assumes that all structural parameters, such as mass, stiffness, and damping have been calculated precisely, and that the earthquakes are known. However, structural parameters are usually difficult to determine precisely if the structures are massive and/or irregular, such as nuclear containments and its internal structures with foundation soil incorporated into the analysis. Faced with these uncertainties, it has been the practice to broaden the floor response spectra peaks by +-10 percent of the peak frequencies on the basis of conservatism. This approach is based on engineering judgement and does not have an analytical basis to provide a sufficient level of confidence in using these spectra for equipment design. To insure reliable design, it is necessary to know structural response variations due to variations in structural properties. This consideration leads to the treatment of structural properties as random variables and the use of probabilistic methods to predict structural response more accurately. New results on floor response spectra of buildings with uncertain structural properties obtained by determining the probabilistic dynamic response from the deterministic dynamic response and its standard deviation are presented. The resulting probabilistic floor response spectra are compared with those obtained deterministically, and are shown to provide a more reliable method for determining seismic forces

    2015-06-01

    Traditionally, pelvic floor retraining for faecal incontinence or obstructed defaecation has been delivered to patients through individual sessions with a specialist pelvic floor nurse, a resource-intensive practice. This study aimed to assess whether a similar outcome can be achieved by delivering retraining to patients in small groups, allowing considerable savings in the use of resources. Data were collected prospectively in a pelvic floor database. Patients received pelvic floor retraining either individually or in a small group setting and completed baseline and follow-up questionnaires. Two hundred and fifteen patients were treated, 119 individually and 96 in a small group setting. Scores before and after treatment for the two settings were compared for the Gastrointestinal Quality of Life Index, the Fecal Incontinence Severity Index and the Patient Assessment of Constipation Symptoms. Additionally patients receiving group treatment completed a short questionnaire on their experience. The median change in Gastrointestinal Quality of Life Index score was 5 (range -62 to 73) for individual treatment and 4 (range -41 to 47) for group treatment, both showing statistically significant improvement. However, there was no significant difference between the settings. Similar results were obtained with the Fecal Incontinence Severity Index and Patient Assessment of Constipation Symptoms scores for the faecal incontinence and obstructed defaecation subgroups respectively. The majority of patients experienced symptomatic improvement following pelvic floor retraining and there was no significant difference in the resulting improvement according to treatment setting. As treatment costs are considerably less in a group setting, group pelvic floor retraining is more cost-effective than individual treatment.

  2. Generation of airborne Listeria innocua from model floor drains.

    Science.gov (United States)

    Berrang, Mark E; Frank, Joseph F

    2012-07-01

    Listeria monocytogenes can colonize floor drains in poultry processing and further processing facilities, remaining present even after cleaning and disinfection. Therefore, during wash down, workers exercise caution to avoid spraying hoses directly into drains in an effort to prevent the escape and transfer of drain microflora to food contact surfaces. The objective of this study was to examine the extent to which an inadvertent water spray into a colonized floor drain can cause the spread of airborne Listeria. Listeria innocua was used to inoculate a polyvinyl chloride model floor drain, resulting in approximately 10(8) cells per ml of phosphate-buffered saline and 10(4) attached cells per square centimeter of inner surface. Each model drain was subjected to a 2-s spray of tap water at 68.9 kPa from a distance of 1 m. Drains were sprayed while filled and again after emptying. Airborne cells were collected by using sedimentation plates containing Listeria selective agar which were placed on the floor and walls of a contained room at incremental horizontal and vertical distances of 0.6, 1.2, 2.4, or 4.0 m from the drain. Sedimentation plates were exposed for 10 min. A mechanical sampler was used to also collect air by impaction on the surface of Listeria selective agar to determine the number of cells per liter of air. The experiment was conducted in triplicate rooms for each of four replications. L. innocua was detected on sedimentation plates on the floor as far as 4.0 m from the drain and on walls as high as 2.4 m above the floor and 4 m from the drain. A 2-s spray with a water hose into a contaminated drain can cause airborne spread of Listeria, resulting in the potential for cross-contamination of food contact surfaces, equipment, and exposed product.

    To compare the degree of pain relief between high-dose (40 mg of triamcinolone acetonide) and low-dose (20 mg of triamcinolone acetonide) corticosteroid injections in patients with severe pain due to adhesive capsulitis. A prospective, randomized, double-blind, dose-comparative study. A total of 32 patients who were diagnosed with adhesive capsulitis and who expressed severe pain intensity, 8 or more points on a numeric rating scale (NRS). Patients received injections of high- or low-dose triamcinolone acetonide under ultrasound guidance. NRS, Shoulder Pain and Disability Index (SPADI), and the passive range of motion (PROM) in four directions were evaluated before and three weeks after the injection. NRS scores showed significant improvement three weeks after the injection in both groups (P = 0.01 in both the low-dose group and high-dose group), but there was no statistically significant difference between the two groups (P = 0.63). SPADI score significantly improved at three weeks after the injection in both groups (P = 0.02 in the low-dose group and P adhesive capsulitis; hence, 20 mg of triamcinolone acetonide can be recommended in patients with adhesive capsulitis with severe pain. © 2017 American Academy of Pain Medicine.

    2014-04-01

    The objective of this study was to validate the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7) in Dutch women. Patients with pelvic floor dysfunction completed the Dutch questionnaires at (1) inclusion to evaluate internal consistency, (2) 1 week later to assess test-retest reliability, and (3) 6 months later to assess responsiveness and interpretability of change. To assess validity, floor and ceiling effects and construct validity were tested. A population-based sample (reference group) completed the questionnaires once. Data of 111 patients and 283 reference group participants were analyzed. Internal consistency of baseline scores in patient and reference groups was moderate (Cronbach's alpha 0.52-0.60) to adequate in the PFDI-20 (Cronbach's alpha 0.71-0.84) and adequate in the PFIQ-7 (Cronbach's alpha 0.88-0.94). Both measures presented adequate test-retest reliability (intraclass correlation coefficient 0.79-0.91) and adequate responsiveness (area under the receiver-operating characteristic curve both 0.77). Interpretability was adequate for PFDI-20 and acceptable for PFIQ-7 with a clinically relevant minimally important change of -23 and -29 points, respectively. At baseline, the scales of the PFIQ-7 showed floor effects (44-55 %) in patients, though the PFIQ-7 summary score did not. No ceiling effects were observed. Construct validity was adequate with all predefined hypotheses confirmed regarding subgroup discrimination using pooled patient and reference group baseline data. For assessing distress and health-related quality of life of pelvic floor dysfunction, the Dutch PFDI-20 and PFIQ-7 are reliable and valid in the general Dutch population, and also responsive and interpretable among tertiary care-seeking women.

    Science.gov (United States)

    Yun, Jaeseok

    2011-01-01

    This paper presents a system of identifying individuals by their gait patterns. We take into account various distinguishable features that can be extracted from a user’s gait and then divide them into two classes: walking pattern and stepping pattern. The conditions we assume are that our target environments are domestic areas, the number of users is smaller than 10, and all users ambulate with bare feet considering the everyday lifestyle of the Korean home. Under these conditions, we have developed a system that identifies individuals’ gait patterns using our biometric sensor, UbiFloorII. We have created UbiFloorII to collect walking samples and created software modules to extract the user’s gait pattern. To identify the users based on the gait patterns extracted from walking samples over UbiFloorII, we have deployed multilayer perceptron network, a feedforward artificial neural network model. The results show that both walking pattern and stepping pattern extracted from users’ gait over the UbiFloorII are distinguishable enough to identify the users and that fusing two classifiers at the matching score level improves the recognition accuracy. Therefore, our proposed system may provide unobtrusive and automatic user identification methods in ubiquitous computing environments, particularly in domestic areas. PMID:22163758

    2009-01-01

    Floor surfaces are notable for the diverse roles that they play in our negotiation of everyday environments. Haptic communication via floor surfaces could enhance or enable many computer-supported activities that involve movement on foot. In this paper, we discuss potential applications of such interfaces in everyday environments and present a haptically augmented floor component through which several interaction methods are being evaluated. We describe two approaches to the design of structured vibrotactile signals for this device. The first is centered on a musical phrase metaphor, as employed in prior work on tactile display. The second is based upon the synthesis of rhythmic patterns of virtual physical impact transients. We report on an experiment in which participants were able to identify communication units that were constructed from these signals and displayed via a floor interface at well above chance levels. The results support the feasibility of tactile information display via such interfaces and provide further indications as to how to effectively design vibrotactile signals for them.

  5. The floor effect: impoverished spatial memory for elevator buttons.

    Science.gov (United States)

    Vendetti, Michael; Castel, Alan D; Holyoak, Keith J

    2013-05-01

    People typically remember objects to which they have frequently been exposed, suggesting that memory is a by-product of perception. However, prior research has shown that people have exceptionally poor memory for the features of some objects (e.g., coins) to which they have been exposed over the course of many years. Here, we examined how people remember the spatial layout of the buttons on a frequently used elevator panel, to determine whether physical interaction (rather than simple exposure) would ensure the incidental encoding of spatial information. Participants who worked in an eight-story office building displayed very poor recall for the elevator panel but above-chance performance on a recognition test. Performance was related to how often and how recently the person had used the elevator. In contrast to their poor memory for the spatial layout of the elevator buttons, most people readily recalled small distinctive graffiti on the elevator walls. In a more implicit test, the majority were able to locate their office floor and the eighth floor button when asked to point toward these buttons when in the actual elevator, with the button labels covered. However, identification was very poor for other floors (including the first floor), suggesting that even frequent interaction with information does not always lead to accurate spatial memory. These findings have implications for understanding the complex relationships among attention, expertise, and memory.

    2012-10-01

    Pelvic floor disorders affect women of all ages and are associated with significant economic burden and poor quality of life. Current literature suggests an association between childbirth and these disorders. In this review, we summarize recent advancements in our understanding of this association. Vaginal childbirth appears to be strongly associated with stress urinary incontinence and pelvic organ prolapse. There is less evidence to suggest an association between vaginal delivery and overactive bladder symptoms. History of more than one perineal laceration increases the likelihood of developing prolapse. Similar association has not been established for episiotomy. Disruption or denervation of structural components of pelvic floor support system, particularly levator ani muscle complex, is associated with later development of pelvic floor disorders. Imbalance in homeostasis of connective tissue remodeling of the vaginal wall from overstretching during childbirth is another possible mechanism. Pelvic floor disorders represent a significant health problem affecting women of all ages. Identification of potential modifiable risk factors and advancement in understanding of the underlying pathophysiology is crucial for primary and secondary prevention of these disorders and for improvement in treatment strategies.

    Full Text Available Background/Aim. Pelvic floor dysfunction is a frequent problem affecting more than 50% of women in peri- and postmenopause. Considering that ageing and menopause befall in the significant factors causing this issue, as well as the expected longevity of women in the world and in our country, pelvic floor dysfunction prevelence is foreseen to be even higher. The aim of the study was to evaluate impact of the symptoms of pelvic dysfunction on quality of life and examine body image satisfaction in adult women with pelvic organ prolapse presenting to tertiary care clinic for surgical treatment. Methods. This prospective case-control study included 50 patients who presented to tertiary care gynecology clinic for surgical treatment and 50 controls with normal pelvic floor support and without urinary incontinence who presented tertiary care gynecology clinic for other reasons. Both, patients and controls, completed two quastionnaires recommended for the evaluation of symptoms (Pelvic floor distress inventory - short forms and quality of life impact (Pelvic floor impact questionnaire - short form of pelvic organ prolapse, and Body Image Scale. Results. The patients scored significantly worse on the prolapse, urinary, colorectal scales and overall score of Pelvic floor distress inventory - 20 than controls subjects (134.91 vs 78.08; p < 0.01. The patients also measured significant decrease in condition- specific quality of life (89.23 vs 3.1; p < 0.01. They were more likely to feel self-conscious (78% vs 42%; p < 0.01, less likely to feel physically attractive (78% vs 22%; p < 0.01, more likely to have difficulty looking at themselves naked (70% vs 42%; p < 0.01, less likely to feel sexually attractive (64% vs 32%; p < 0.01, and less likely to feel feminine (56% vs 16%; p < 0.05, than controls. There were no differencies in their feeling of dissatisfaction with appearance when dressed, avoiding people because of appereance and overall dissatisfaction with

    The mechanical properties of dance floors have the potential to influence dancers' performance and injury risk. Little information is available that describes dancers' preferences for dance floor mechanical properties. Investigation of dancers' perceptions of varied dance floors can serve to enlighten governing bodies, floor manufacturers, and the dance community. The aim of this study was to assess the perceptions of dancers from a touring professional ballet company regarding four floors with varied force reduction (FR) that were created to replicate those used by the company in normal dance training and performance. A specialized questionnaire was developed that incorporated a series of qualitative and quantitative measures that could be used by participants to express their perceptions of the custom built dance floors. Floor FR was quantified with reference to the protocols specified by European standards. Dancer perceptions were in general agreement with floor FR values; however, some discrepancies were observed. Dancers expressed a preference for floor FR within the mid to upper limits (57% to 72%) of the European standards, although a minority preferred low FR (approximately 36%) floors. A limited ability to perceive inconsistencies in FR across test floors was observed, which may have implications for injury risk. Investigation of the perceptions of dancers from more diverse backgrounds, on floors that provide a closer representation of typical dance studio and stage sizes, over longer periods of time, would provide further insight into the perceptual and adaptive responses of dancers to varied floor mechanical properties.

  14. Statistical Analysis Of Tank 19F Floor Sample Results

    2010-01-01

    Representative sampling has been completed for characterization of the residual material on the floor of Tank 19F as per the statistical sampling plan developed by Harris and Shine. Samples from eight locations have been obtained from the tank floor and two of the samples were archived as a contingency. Six samples, referred to in this report as the current scrape samples, have been submitted to and analyzed by SRNL. This report contains the statistical analysis of the floor sample analytical results to determine if further data are needed to reduce uncertainty. Included are comparisons with the prior Mantis samples results to determine if they can be pooled with the current scrape samples to estimate the upper 95% confidence limits (UCL95%) for concentration. Statistical analysis revealed that the Mantis and current scrape sample results are not compatible. Therefore, the Mantis sample results were not used to support the quantification of analytes in the residual material. Significant spatial variability among the current scrape sample results was not found. Constituent concentrations were similar between the North and South hemispheres as well as between the inner and outer regions of the tank floor. The current scrape sample results from all six samples fall within their 3-sigma limits. In view of the results from numerous statistical tests, the data were pooled from all six current scrape samples. As such, an adequate sample size was provided for quantification of the residual material on the floor of Tank 19F. The uncertainty is quantified in this report by an UCL95% on each analyte concentration. The uncertainty in analyte concentration was calculated as a function of the number of samples, the average, and the standard deviation of the analytical results. The UCL95% was based entirely on the six current scrape sample results (each averaged across three analytical determinations).

  19. Pyroclastic Deposits in the Floor-fractured Crater Alphonsus

    Alphonsus, the 118 km diameter floor-fractured crater, is located immediately east of Mare Nubium. Eleven pyroclastic deposits have been identified on the crater's floor. Early telescopic spectra suggest that the floor of Alphonsus is noritic, and that the pyroclastic deposits contain mixtures of floor material and a juvenile component including basaltic glass. Head and Wilson contend that Nubium lavas intruded the breccia zone beneath Alphonsus, forming dikes and fractures on the crater floor. In this model, the magma ascended to the level of the mare but cooled underground, and a portion broke thru to the surface in vulcanian (explosive) eruptions. Alternatively, the erupted material could be from a source unrelated to the mare, in the style of regional pyroclastic deposits. High-resolution images and spectroscopy from the Moon Mineralogy Mapper (M3), Diviner Lunar Radiometer, and Lunar Reconnaissance Orbiter Camera Narrow Angle Camera (NAC) provide data to test these formation models. Spectra from M3 confirm that the crater floor is primarily composed of noritic material, and that the Nubium lavas are basaltic. Spectra from the three largest pyroclastic deposits in Alphonsus are consistent with a minor low- Ca pyroxene component in a glass-rich matrix. The centers of the 2 micron absorption bands have wavelengths too short to be of the same origin as the Nubium basalts. Diviner Christiansen feature (CF) values were used to estimate FeO abundances for the crater floor, Nubium soil, and pyroclastic deposits. The estimated abundance for the crater floor (7.5 +/- 1.4 wt.%) is within the range of FeO values for Apollo norite samples. However, the estimated FeO abundance for Nubium soil (13.4 +/- 1.4 wt.%) is lower than those measured in most mare samples. The difference may reflect contamination of the mare soil by highland ejecta. The Diviner-derived FeO abundance for the western pyroclastic deposit is 13.8 +/- 3.3 wt.%. This is lower than the values for mare soil

    On September 28, 2015, debris collected from the PRF (236-Z) canyon floor, Pan J, was observed to exhibit chemical reaction. The material had been transferred from the floor pan to a collection tray inside the canyon the previous Friday. Work in the canyon was stopped to allow Industrial Hygiene to perform monitoring of the material reaction. Canyon floor debris that had been sealed out was sequestered at the facility, a recovery plan was developed, and drum inspections were initiated to verify no additional reactions had occurred. On October 13, in-process drums containing other Pan J material were inspected and showed some indication of chemical reaction, limited to discoloration and degradation of inner plastic bags. All Pan J material was sealed back into the canyon and returned to collection trays. Based on the high airborne levels in the canyon during physical debris removal, ETGS (Encapsulation Technology Glycerin Solution) was used as a fogging/lock-down agent. On October 15, subject matter experts confirmed a reaction had occurred between nitrates (both Plutonium Nitrate and Aluminum Nitrate Nonahydrate (ANN) are present) in the Pan J material and the ETGS fixative used to lower airborne radioactivity levels during debris removal. Management stopped the use of fogging/lock-down agents containing glycerin on bulk materials, declared a Management Concern, and initiated the Potential Inadequacy in the Safety Analysis determination process. Additional drum inspections and laboratory analysis of both reacted and unreacted material are planned. This report compiles the results of many different sample analyses conducted by the Pacific Northwest National Laboratory on samples collected from the Plutonium Reclamation Facility (PRF) floor pans by the CH2MHill’s Plateau Remediation Company (CHPRC). Revision 1 added Appendix G that reports the results of the Gas Generation Rate and methodology. The scope of analyses requested by CHPRC includes the determination of

    Slips and falls are a leading cause of injury at work. Few studies, however, have systematically examined risk factors of slipping outside the laboratory environment. This study examined the association between floor surface characteristics, slip-resistant shoes, floor cleaning frequency and the risk of slipping in limited-service restaurant workers. 475 workers from 36 limited-service restaurants from three major chains in six states in the USA were recruited to participate in a prospective cohort study of workplace slipping. Kitchen floor surface roughness and coefficient of friction (COF) were measured in eight working areas and then averaged within each restaurant. The use of slip-resistant shoes was determined by examining the participant's shoes and noting the presence of a 'slip-resistant' marking on the sole. Restaurant managers reported the frequency of daily kitchen floor cleaning. Participants reported their slip experience and work hours weekly for up to 12 weeks. The survey materials were made available in three languages: English, Spanish and Portuguese. The associations between rate of slipping and risk factors were assessed using a multivariable negative binomial generalised estimating equation model. The mean of individual slipping rate varied among the restaurants from 0.02 to 2.49 slips per 40 work hours. After adjusting for age, gender, BMI, education, primary language, job tenure and restaurant chain, the use of slip-resistant shoes was associated with a 54% reduction in the reported rate of slipping (95% CI 37% to 64%), and the rate of slipping decreased by 21% (95% CI 5% to 34%) for each 0.1 increase in the mean kitchen COF. Increasing floor cleaning frequency was significantly associated with a decreasing rate of slipping when considered in isolation but not after statistical adjustment for other factors. These results provide support for the use of slip-resistant shoes and measures to increase COF as preventive interventions to reduce slips

    About 200 Floor Fractured Craters (FFCs) have been identified by Schultz (1976) on the Moon, mainly around the lunar maria. These craters are a class of impact craters that are distinguished by having radi-ally and concentric floor-fractured networks and ab-normally shallow floors. In some cases, the uplift of the crater floor can be as large as 50% of the initial crater depth. These impact craters are interpreted to have undergone endogenous deformations after their formation.

    In this paper, we utilize novel sensors built-in commercial smart devices to propose a schema which can identify floors with high accuracy and efficiency. This schema can be divided into two modules: floor identifying and floor change detection. Floor identifying module starts at initial phase of positioning, and responsible for determining which floor the positioning start. We have estimated two methods to identify initial floor based on K-Nearest Neighbors (KNN) and BP Neural Network, respectively. In order to improve performance of KNN algorithm, we proposed a novel method based on weighting signal strength, which can identify floors robust and quickly. Floor change detection module turns on after entering into continues positioning procedure. In this module, sensors (such as accelerometer and barometer) of smart devices are used to determine whether the user is going up and down stairs or taking an elevator. This method has fused different kinds of sensor data and can adapt various motion pattern of users. We conduct our experiment with mobile client on Android Phone (Nexus 5) at a four-floors building with an open area between the second and third floor. The results demonstrate that our scheme can achieve an accuracy of 99% to identify floor and 97% to detecting floor changes as a whole.

    2009-07-01

    This publication assesses the long-term economic and climatic effects of introducing price caps and price floors in hypothetical global climate change mitigation policy. Based on emission trends, abatement costs and equilibrium climate sensitivity from IPCC and IEA reports, this quantitative analysis confirms that price caps could significantly reduce economic uncertainty. This uncertainty stems primarily from unpredictable economic growth and energy prices, and ultimately unabated emission trends. In addition, the development of abatement technologies is uncertain. Furthermore,this analysis shows that rigid targets may entail greater economic risks with little or no comparative advantage for the climate. More ambitious emission objectives, combined with price caps and price floors, could still entail significantly lower expected costs while driving similar, or even slightly better, climatic outcomes in probabilistic terms.

    Chatoor, Dave; Soligo, Marco; Emmanuel, Anton

    2009-01-01

    The evolution of the multidisciplinary approach to the management of chronic conditions is a reflection of how medicine has evolved from a singular to a plural effort recognising the complex causations and consequences of such disorders. This thinking should not be confined to tertiary centres alone and should be adapted where local expertise is available. Such an approach is especially important in pelvic floor disorders, where the correlation between structure and function is not always straightforward. There is a need to avoid over-investigation by accurate clinical assessment allied to tailored investigation, leading to a step-wise approach to treatment (which may include behavioural, physiotherapy, medical or surgical management). The algorithms here on faecal incontinence, obstetric trauma, pelvic floor prolapse and chronic pelvic pain attempt to provide such a logical approach to patients.

  17. Systematic evaluations of probabilistic floor response spectrum generation

    International Nuclear Information System (INIS)

    Lilhanand, K.; Wing, D.W.; Tseng, W.S.

    1985-01-01

    The relative merits of the current methods for direct generation of probabilistic floor response spectra (FRS) from the prescribed design response spectra (DRS) are evaluated. The explicit probabilistic methods, which explicitly use the relationship between the power spectral density function (PSDF) and response spectra (RS), i.e., the PSDF-RS relationship, are found to have advantages for practical applications over the implicit methods. To evaluate the accuracy of the explicit methods, the root-mean-square (rms) response and the peak factor contained in the PSDF-RS relationship are systematically evaluated, especially for the narrow-band floor spectral response, by comparing the analytical results with simulation results. Based on the evaluation results, a method is recommended for practical use for the direct generation of probabilistic FRS. (orig.)

    Cui, Zimo; Chanda, Emmanuel; Zhao, Jingli; Wang, Zhihe

    2018-01-01

    Although longwall top-coal caving (LTCC) has been a popular, more productive and cost-effective method in recent years, roadway floor heave and rock bursts frequently appear when exploiting such coal seams with large dip angle. This paper proposes addressing this problem by adopting three-dimensional roadway layout of stagger arrangement (3-D RLSA). In this study, the first step was to analyse the stress distribution characteristics in the vicinity of coal seam floor based on the stress slip line field theory. In the second step, numerical calculation using FLAC3D was conducted. Finally, an evaluation of the 3-D RLSA for solving this particular issue was given. Results indicate that for this particular mine the proposed 3-D RLSA results in 24% increase in the coal recovery ratio and a modest reduction in excavation and maintenance costs compared to the conventional LTCC method.

Participative ergonomics and user-centred design approaches were used. The material collected was reviewed to better understand the floor layers' viewpoints on sustainability. The solutions that were retained and the challenges encountered to make material handling and physical work easier and to develop training and a website are presented. The importance of OHS as a sustainability factor, its structuring effect, what distinguishes MiE from small businesses and possible strategies for workings with them are also discussed.

    A study was undertaken to investigate the influence of soil-structure interaction on floor response spectra developed in typical nuclear power plant structures. A horizontal earthquake time history, whose spectra envelops the Regulatory Guide 1.60 criteria and is scaled to a log peak acceleration, was used as input to structural models. Two different structural stick models were used, representing typical BWR and PWR facilities. By varying the structural and soil stiffness parameters, a wide range of system behaviors were investigated. Floor response spectra, required to assess equipment qualification, were of primary interest. It was found from a variation of parameter study that the interaction soil parameters, particularly radiation damping, greatly affect the nature of the calculated responses. 2 refs., 2 figs., 2 tabs

    The Brief discuss primarily two aspects of air flow management in raised floor data centers. Firstly, cooling air delivery through perforated tiles will be examined and influence of the tile geometry on flow field development and hot air entrainment above perforated tiles will be discussed. Secondly, the use of cold aisle containment to physically separate hot and cold regions, and minimize hot and cold air mixing will be presented. Both experimental investigations and computational efforts are discussed and development of computational fluid dynamics (CFD) based models for simulating air flow in data centers is included. In addition, metrology tools for facility scale air velocity and temperature measurement, and air flow rate measurement through perforated floor tiles and server racks are examined and the authors present thermodynamics-based models to gauge the effectiveness and importance of air flow management schemes in data centers.

  8. Modern Theories of Pelvic Floor Support : A Topical Review of Modern Studies on Structural and Functional Pelvic Floor Support from Medical Imaging, Computational Modeling, and Electromyographic Perspectives.

    Weakened pelvic floor support is believed to be the main cause of various pelvic floor disorders. Modern theories of pelvic floor support stress on the structural and functional integrity of multiple structures and their interplay to maintain normal pelvic floor functions. Connective tissues provide passive pelvic floor support while pelvic floor muscles provide active support through voluntary contraction. Advanced modern medical technologies allow us to comprehensively and thoroughly evaluate the interaction of supporting structures and assess both active and passive support functions. The pathophysiology of various pelvic floor disorders associated with pelvic floor weakness is now under scrutiny from the combination of (1) morphological, (2) dynamic (through computational modeling), and (3) neurophysiological perspectives. This topical review aims to update newly emerged studies assessing pelvic floor support function among these three categories. A literature search was performed with emphasis on (1) medical imaging studies that assess pelvic floor muscle architecture, (2) subject-specific computational modeling studies that address new topics such as modeling muscle contractions, and (3) pelvic floor neurophysiology studies that report novel devices or findings such as high-density surface electromyography techniques. We found that recent computational modeling studies are featured with more realistic soft tissue constitutive models (e.g., active muscle contraction) as well as an increasing interest in simulating surgical interventions (e.g., artificial sphincter). Diffusion tensor imaging provides a useful non-invasive tool to characterize pelvic floor muscles at the microstructural level, which can be potentially used to improve the accuracy of the simulation of muscle contraction. Studies using high-density surface electromyography anal and vaginal probes on large patient cohorts have been recently reported. Influences of vaginal delivery on the

  10. Urinary incontinence, pelvic floor dysfunction, exercise and sport.

    Science.gov (United States)

    Bø, Kari

    2004-01-01

    Urinary incontinence is defined as "the complaint of any involuntary leakage of urine" and is a common problem in the female population with prevalence rates varying between 10% and 55% in 15- to 64-year-old women. The most frequent form of urinary incontinence in women is stress urinary incontinence, defined as "involuntary leakage on effort or exertion, or on sneezing or coughing". The aim of this article is to systematically review the literature on urinary incontinence and participation in sport and fitness activities with a special emphasis on prevalence and treatment in female elite athletes. Stress urinary incontinence is a barrier to women's participation in sport and fitness activities and, therefore, it may be a threat to women's health, self-esteem and well-being. The prevalence during sports among young, nulliparous elite athletes varies between 0% (golf) and 80% (trampolinists). The highest prevalence is found in sports involving high impact activities such as gymnastics, track and field, and some ball games. A 'stiff' and strong pelvic floor positioned at an optimal level inside the pelvis may be a crucial factor in counteracting the increases in abdominal pressure occurring during high-impact activities. There are no randomised controlled trials or reports on the effect of any treatment for stress urinary incontinence in female elite athletes. However, strength training of the pelvic floor muscles has been shown to be effective in treating stress urinary incontinence in parous females in the general population. In randomised controlled trials, reported cure rates, defined as athletes than in other women. There is a need for more basic research on pelvic floor muscle function during physical activity and the effect of pelvic floor muscle training in female elite athletes.

  14. SIMON: A mobile robot for floor contamination surveys

    International Nuclear Information System (INIS)

    Dudar, E.; Teese, G.; Wagner, D.

    1991-01-01

    The Robotics Development group at the Savannah River Site is developing an autonomous robot to perform radiological surveys of potentially contaminated floors. The robot scans floors at a speed of one-inch/second and stops, sounds an alarm, and flashes lights when contamination in a certain area is detected. The contamination of interest here is primarily alpha and beta-gamma. The contamination levels are low to moderate. The robot, a Cybermotion K2A, is radio controlled, uses dead reckoning to determine vehicle position, and docks with a charging station to replenish its batteries and calibrate its position. It has an ultrasonic collision avoidance system as well as two safety bumpers that will stop the robot's motion when they are depressed. Paths for the robot are preprogrammed and the robot's motion can be monitored on a remote screen which shows a graphical map of the environment. The radiation instrument being used is an Eberline RM22A monitor. This monitor is microcomputer based with a serial I/O interface for remote operation. Up to 30 detectors may be configured with the RM22A. For our purposes, two downward-facing gas proportional detectors are used to scan floors, and one upward-facing detector is used for radiation background compensation. SIMON is interfaced with the RM22A in such a way that it scans the floor surface at one-inch/second, and if contamination is detected, the vehicle stops, alarms, and activates a voice synthesizer. Future development includes using the contamination data collected to provide a graphical contour map of a contaminated area. 3 refs

    2013-01-01

    The available floor space has a strong impact on the execution of various behaviours of laying hens. Presently, in Germany detailed requirements on the housing of pullets are insufficient. In order to get a first approximation, the floor space covered by pullets was determined by the colour contrast planimetric method KobaPlan. The measurements on standing and sitting pullets were done on a random sample of Lohmann Brown (LB), Lohmann Tradition (LT), Lohmann Selected Leghorn (LSL) and Dekalb White (DW) hybrids from the 6th week of life to 18/20 weeks at regular intervals. The hens were weighed and photographed digitally in a specific planimetric box (n = 2600 photographs from pullets in standing and 1360 in sitting position). Afterwards the KobaPlan software program calculated the animal area.The results showed a correlation between floor space covered by the pullets in standing position and the live weight (R2 = 0.80-0.96). The mean floor space covered by LB and LT at the end of rearing (body weight 1450 +/- 25 g LB and 1500 +/- 25 g LT) was 422.4 +/- 41.9 cm2 (LB) and 446.7 +/- 49.0 cm2 (LT) stand- ing, respectively 448.0 +/- 51.0 cm2 (LB) and 464.5 +/- 42.6 cm2 (LT) sitting. LSL and DW (body weight 1300 +/- 25 g) used 371.0 +/- 41.3 cm2 (LSL) and 349.3 +/- 26.3 cm2 (DW), respectively in standing and 379.5 +/- 41.2 cm2 (LSL) in sitting position. Maximum stocking density recommendation for pullets based on these planimetric results compared with the space allowance in alternative housing systems for laying hens are between eleven and 14 birds/m2. To verify this stocking density recommendation for pullets further studies should be complemented by specific ethological observations.

  17. PHASE CHANGE MATERIALS IN FLOOR TILES FOR THERMAL ENERGY STORAGE

    Energy Technology Data Exchange (ETDEWEB)

    Douglas C. Hittle

    2002-10-01

    Passive solar systems integrated into residential structures significantly reduce heating energy consumption. Taking advantage of latent heat storage has further increased energy savings. This is accomplished by the incorporation of phase change materials into building materials used in passive applications. Trombe walls, ceilings and floors can all be enhanced with phase change materials. Increasing the thermal storage of floor tile by the addition of encapsulated paraffin wax is the proposed topic of research. Latent heat storage of a phase change material (PCM) is obtained during a change in phase. Typical materials use the latent heat released when the material changes from a liquid to a solid. Paraffin wax and salt hydrates are examples of such materials. Other PCMs that have been recently investigated undergo a phase transition from one solid form to another. During this process they will release heat. These are known as solid-state phase change materials. All have large latent heats, which makes them ideal for passive solar applications. Easy incorporation into various building materials is must for these materials. This proposal will address the advantages and disadvantages of using these materials in floor tile. Prototype tile will be made from a mixture of quartz, binder and phase change material. The thermal and structural properties of the prototype tiles will be tested fully. It is expected that with the addition of the phase change material the structural properties will be compromised to some extent. The ratio of phase change material in the tile will have to be varied to determine the best mixture to provide significant thermal storage, while maintaining structural properties that meet the industry standards for floor tile.

    To investigate the relationship between pelvic floor symptoms using the Pelvic Floor Bother Questionnaire (PFBQ) and the Pelvic Organ Prolapse Quantification system (POP-Q) measurements. This was a retrospective study. Consecutive women seeking care for pelvic floor symptoms were evaluated. The PFBQ was self-administered by all patients before they were examined by three urogynecologists according to the POP-Q. Pearson's correlation and a receiver operating characteristic (ROC) curve were used to investigate relationship between symptoms and POP-Q findings. Four hundred and sixty-seven patients completed the questionnaire and underwent standardized pelvic examination. Anterior, posterior and apical compartment prolapse were found in 95.5%, 78.8% and 35.9%, respectively. Moderate correlations were found between a feeling of bulging and the increasing severity of prolapse of all compartments. For all 8 pelvic floor symptoms, the area under the curve for a feeling of bulge with point Ba and point C was significantly greater than 0.7, suggesting fair ability to predict symptomatic patients. The sensitivity and specificity of the symptom were 60% and 83% when point Ba was 1 cm below the hymen. Whereas they were 55% and 83% when point C was 3 cm above the hymen. The feeling of a bulge in the vagina is the only symptom that correlated with prolapse of all compartments. The specific thresholds for the feeling of a bulge appear to be 1 cm below the hymen for anterior vaginal wall prolapse, and 3 cm above the hymen for apical prolapse. Neurourol.

    Women with pelvic floor dysfunction can have tender areas on vaginal examination, which can be treated with trigger-point injections. There are no publications to evaluate the accuracy of pelvic floor muscle injections. Trigger-point injections were performed on 2 fresh cadaveric pelvises using a curved nasal cannula guide and 7-in spinal needle. This was performed using our standard template of 2 sets of injections at the 1-, 3-, and 5-o'clock positions distally and proximally. The first pelvis was dissected to examine dye penetration. Based on these results, we modified our technique and repeated the injections on the second cadaver. We dissected the second pelvis and compared our findings. The 1-o'clock proximal and distal injections stained the obturator internus and externus near the insertion at the ischiopubic ramus. The 3-o'clock injections stained the midbody of the pubococcygeus and puborectalis. The distal 5-o'clock position was too deep and stained the fat of the ischiorectal space. The proximal 5-o'clock injection stained the area of the pudendal nerve. Our goal at the distal 5-o'clock position was to infuse the iliococcygeus muscle, so we shortened the needle depth from 2 to 1 cm beyond the cannula tip. In our second dissection, the distal 5-o'clock injection again stained only the fat of the ischiorectal space. This is the first study to characterize the distribution of pelvic floor muscle injections in a cadaver model and confirms the ability to deliver medications effectively to the pelvic floor muscles.

    The objectives of this study were (i) to evaluate different fracture mechanisms for orbital floor fractures and (ii) to measure forces and displacement of intraorbital tissue after orbital traumata to predict the necessity of strength for reconstruction materials. Six fresh frozen human heads were used, and orbital floor defects in the right and left orbit were created by a direct impact of 3.0 J onto the globe and infraorbital rim, respectively. Orbital floor defect sizes and displacement were evaluated after a Le Fort I osteotomy. In addition, after reposition of the intraorbital tissue, forces and displacement were measured. The orbital floor defect sizes were 208.3 (SD, 33.4) mm(2) for globe impact and 221.8 (SD, 53.1) mm(2) for infraorbital impact. The intraorbital tissue displacement after the impact and before reposition was 5.6 (SD, 1.0) mm for globe impact and 2.8 (SD, 0.7) mm for infraorbital impact. After reposition, the displacement was 0.8 (SD, 0.5) mm and 1.1 (SD, 0.7) mm, respectively. The measured applied forces were 0.061 (SD, 0.014) N for globe impact and 0.066 (SD, 0.022) N for infraorbital impact. Different fracture-inductive mechanisms are not reflected by the pattern of the fracture. The forces needed after reposition are minimal (~0.07 N), which may explain the success of PDS foils [poly-(p-dioxanone)] and collagen membranes as reconstruction materials.

  4. Pelvic floor disorders in gynecological malignancies. An overlooked problem?

    2018-04-01

    Full Text Available Cervical, endometrial, ovarian, vulvar, and vaginal cancers affect women of a broad age spectrum. Many of these women are still sexually active when their cancer is diagnosed. Treatment options for gynecological malignancies, such as gynecological surgery, radiation, and chemotherapy, are proven risk factors for pelvic floor dysfunction. The prevalence of urinary incontinence, fecal incontinence, and sexual dysfunction before cancer treatment is still unclear. Hypotheses have been raised in the literature that these manifestations could represent early symptoms of pelvic cancers, but most remain overlooked even in cancer surviving patients. The primary focus of therapy is always cancer eradication, but as oncological and surgical treatment options become more successful, the number of cancer survivors increases. The quality of life of patients with gynecological cancers often remains an underrated subject. Pelvic floor disorders are not consistently reported by patients and are frequently overlooked by many clinicians. In this brief review we discuss the importance of pelvic floor dysfunction in patients with gynecological malignant tumors.

    1997-01-01

    The floors of the K Basins at the Hanford Site are refinished to make decontamination easier if spills occur as the spent nuclear fuel (SNF) is being unloaded from the basins for shipment to dry storage. Without removing the contaminated existing coating, the basin floors are to be coated with an epoxy coating material selected on the basis of the results of field tests of several paint products. The floor refinishing activities must be reviewed by a management review board to ensure that work can be performed in a controlled manner. Major documents prepared for management board review include a report on maintaining radiation exposure as low as reasonably achievable, a waste management plan, and reports on hazard classification and unreviewed safety questions. To protect personnel working in the radiation zone, Operational Health Physics prescribed the required minimum protective methods and devices in the radiological work permit. Also, industrial hygiene safety must be analyzed to establish respirator requirements for persons working in the basins. The procedure and requirements for the refinishing work are detailed in a work package approved by all safety engineers. After the refinishing work is completed, waste materials generated from the refinishing work must be disposed of according to the waste management plan

    Obesity is one of the well-documented risk factors of pelvic floor disorders (PFDs). The PFDs include urinary and fecal incontinence (UI, FI) and pelvic organ prolapse (POP). Surgery-induced weight loss improves different kinds of incontinence as well as POP symptoms. However, there is a lack of evidence how bariatric surgery influences pelvic floor anatomy and function in women without previous PFDs and whether it may be concerned as PFD prophylaxis tool. The present analysis is a prospective, non-randomized case-control study from January 2014 to September 2017. Participants underwent pelvic floor ultrasound examination with bladder neck position estimation at rest, during levator ani tension, and at Valsalva maneuver before surgery and 12-18 months after. Pelvic organ prolapse quantification (POPQ) > 2 stage and PFD complaints were the exclusion criteria. Fifty-nine patients underwent bariatric surgery (57 sleeve gastrectomy and 2 gastric bypass). Mean BMI decreased from 43.8 ± 5.9 to 29 ± 4.6 kg/m 2 after surgery (p elevation at tension after weight loss. Bariatric surgery is associated with a betterment of bladder neck position at rest, tension, and Valsalva maneuver in women without PFDs. We postulate that bariatric surgery may be a tool for PFD prevention. It does not improve levator ani function and does not limit bladder neck mobility, which implicates that it has no influence on preexisting pelvic dysfunction.

English and Spanish versions were administered to 50 Hispanic/Latina women with pelvic symptoms. Kappa correlations of items and correlation coefficients for scales were computed. Psychometric testing for translations demonstrated good (0.80-0.89), very good (0.90-0.95), or excellent (>0.95) correlations for primary scales of the PFDI, PFIQ, MESA, Hunskaar, PISQ, and LOT. Strict translation techniques and testing yielded valid Spanish translations of instruments assessing pelvic symptoms/functional life impact in women with pelvic floor disorders.

    Pelvic floor disorders are highly prevalent in women of all ages and can greatly impair quality of life. Pelvic floor muscle training (PFMT) is a viable treatment option for several pelvic floor conditions including urinary incontinence and pelvic organ prolapse. PFMT is a program of therapy initiated by an experienced clinician (e.g., women's health or urology nurse practitioner (NP), physical therapist (PT)) that involves exercises for women with stress urinary incontinence (UI) and exercises combined with behavioral or conservative treatments (lifestyle changes, bladder training with urge suppression) for women with urgency or mixed UI. These exercise programs are more comprehensive than simple Kegel exercises. Despite evidence-based research indicating the efficacy and cost-effectiveness for treatment of urinary incontinence, PFMT is not commonly used as a first-line treatment in clinical practice in the USA (Abrams et al., 2012). This article will review PFMT for the treatment of UI and pelvic organ prolapse (POP) and theorize how this conservative therapy can be utilized more effectively in the USA.

    To assess function and prevalence of spasms and trigger points of the pelvic floor muscles in women with deep endometriosis. One hundred and four (104) patients were assessed. Group 1 (G1) was composed of 52 subjects diagnosed with deep endometriosis proven by magnetic resonance imaging (MRI); Group 2 (G2) was composed of 52 women with no signs of endometriosis. Subjects from both G1 and G2 were seen at the Division of Pelvic Pain and Endometriosis and at Center for Prevention of Sexually Transmitted Diseases, both at Federal University of São Paulo (UNIFESP), respectively. A full physical therapy evaluation was carried out, including medical history, presence of dyspareunia and physical examination, which included detailed evaluation of pelvic floor muscles and occurrence of muscle spasm, trigger point and muscle function. The average age of the subjects in the study group was 36.4 and 30.9 years in the control group (p = 0.002). A greater prevalence of deep dyspareunia was found in the subjects in the endometriosis group when compared to the control group (p = 0.010). Women in G1 had higher prevalence of muscle spasms. In this group, 53.9 % had spasms-compared to only 17.3 % of women in G2 (p pelvic floor muscle spasms when compared to the control group.

  10. Evaluation of the thermal comfort of ceramic floor tiles

    Full Text Available In places where people are bare feet, the thermal sensation of cold or hot depends on the environmental conditions and material properties including its microstructure and crustiness surface. The uncomforting can be characterized by heated floor surfaces in external environments which are exposed to sun radiation (swimming polls areas or by cold floor surfaces in internal environments (bed rooms, path rooms. The property named thermal effusivity which defines the interface temperature when two semi-infinite solids are putted in perfect contact. The introduction of the crustiness surface on the ceramic tiles interferes in the contact temperature and also it can be a strategy to obtain ceramic tiles more comfortable. Materials with low conductivities and densities can be obtained by porous inclusion are due particularly to the processing conditions usually employed. However, the presence of pores generally involves low mechanical strength. This work has the objective to evaluate the thermal comfort of ceramics floor obtained by incorporation of refractory raw materials (residue of the polishing of the porcelanato in industrial atomized ceramic powder, through the thermal and mechanical properties. The theoretical and experimental results show that the porosity and crustiness surface increases; there is sensitive improvement in the comfort by contact.

  11. Analysis of an Attached Sunspace with a Thermal Inertia Floor

    2018-05-01

    Full Text Available An attached sunspace is a partially or fully glazed enclosure, usually located on the first floor, facing south (in the Northern Hemisphere and adjacent to a conditioned room. Because of the length and orientation of the glazed area, the temperature in the sunspace is usually higher than outside the building. As a Trombe–Mitchel wall, the sunspace has a considerable mass that accumulates thermal energy, but in this case the thermal mass is located in the floor. This capacity to accumulate thermal energy confers the attached sunspace features beyond passive insulation. The sunspace studied in this paper is part of an experimental building located in the North of Spain that was built in the frame of the so-called ARFRISOL project. It consists of a south-facing glazed exterior wall with both clear glass and semi-transparent photovoltaic panels, an intermediate space with a thick layer of sand over a concrete floor, and a partially glazed interior wall. In this paper, a three-dimensional computational model has been implemented to analyse the thermal behaviour inside the sunspace. This analysis takes into account, among other factors, the effects of sun position, incident solar irradiation and temperature both inside and outside.

  12. Constructive solutions for beamless capitalless floors with prestressed reinforcement

    2014-07-01

    Full Text Available In the article the authors present advanced constructions of prestressed reinforced concrete flat ceiling, where high-strength ropes in elastic shell are used as stressed reinforcement. The novelty of the solution lays in diagonal arrangement of hard valves and use of high-strength ropes in a flexible shell of "Monostrand" type. This type of prestress, in our opinion, is the most acceptable from technical point of view for selective reinforcement of separate tense rods or cables. The use of pre-stressed reinforcement in the form of individual rods or cables increases the rigidity and crack resistance of concrete beamless slabs. The use of high-strength ropes in the monostrand-type shell makes it possible to prestress in frames of single cell plate or floor in general and to reduce labour input for stressing armature. The paper presents original solution with diagonal position of the valve. The authors suggest the use of prestressed diagonal valves as in all cells of the floor with the cells of the same or only slightly different size and in separate cells of the floor (for roofs with different cells. The diagonal location of stressed reinforcement proposed in the work is an efficient solution for extending the range of dimensions and loads size.

    Terrestrial ecosystems, mainly plants, emit large amounts of volatile organic compounds (VOCs) into the atmosphere. In addition to plants, VOCs also have less-known sources, such as soil. VOCs are a very diverse group of reactive compounds, including terpenoids, alcohols, aldehydes and ketones. Due to their high reactivity, VOCs take part in formation and growth of secondary organic aerosols in the atmosphere and thus affect also Earth's radiation balance (Kulmala et al. 2004). We have studied boreal soil and forest floor VOC fluxes with chamber and snow gradient techniques we were developed. Spatial and temporal variability in VOC fluxes was studied with year-round measurements in the field and the sources of boreal soil VOCs in the laboratory with fungal isolates. Determination of the compounds was performed mass spectrometrically. Our results reveal that VOCs from soil are mainly emitted by living roots, above- and belowground litter and microbes. The strongest source appears to be litter, in which both plant residuals and decomposers play a role in the emissions. Soil fungi showed high emissions of lighter VOCs, like acetone, acetaldehyde and methanol, from isolates. Temperature and moisture are the most critical physical factors driving VOC fluxes. Since the environment in boreal forests undergoes strong seasonal changes, the VOC flux strength of the forest floor varies markedly during the year, being highest in spring and autumn. The high spatial heterogeneity of the forest floor was also clearly visible in VOC fluxes. The fluxes of other trace gases (CO2, CH4 and N2O) from soil, which are also related to the soil biological activity and physical conditions, did not show correlations with the VOC fluxes. These results indicate that emissions of VOCs from the boreal forest floor account for as much as several tens of percent, depending on the season, of the total forest ecosystem VOC emissions. This emphasises that forest floor compartment should be taken into

    2017-12-13

    Hypopressive abdominal gymnastics has been proposed as a new paradigm in rehabilitating the pelvic floor. Its claims contraindicate the recommendation for pelvic floor muscle training during the postpartum period. To determine whether hypopressive abdominal gymnastics is more effective than pelvic floor muscle training or other alternative conservative treatments for rehabilitating the pelvic floor. We consulted the databases of the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Library, Latin American and Caribbean Health Sciences Literature (LILACS), Physiotherapy Evidence Database (PEDro), PubMed, Scopus, Trip Database and Web of Science. We selected systematic reviews, clinical trials and analytical studies that assessed the efficacy of hypopressive abdominal gymnastics in women. The measured outcomes were the strengthening of the pelvic floor muscles, the incidence of urine incontinence or prolapse and symptom remission. We included 4 clinical trials, whose quality was measured with the PEDro scale. Hypopressive gymnastics is less effective than pelvic floor muscle training for activating pelvic floor muscles, achieving closure of the levator hiatus of the anus and increasing pelvic floor muscle thickness, strength and resistance. The evidence reviewed does not support the recommendation for hypopressive abdominal gymnastics for strengthening the pelvic floor either during the postpartum period or outside that period. Pelvic floor muscle training remains the first-line treatment for pelvic floor dysfunction. There is a lack of quality clinical trials that have evaluated the efficacy of hypopressive abdominal gymnastics. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    To determine whether symptoms of urinary incontinence is reduced by pelvic floor muscle training, to determine whether urinary incontinence can be totally eliminated by strengthening the pelvic floor muscle to grade 5 on the Oxford scale. Prospective randomized controlled clinical trial. Outpatient urogynecology department. One hundred thirty cases with stress and mixed urinary incontinence. All participants were randomly allocated to the pelvic floor muscle training group or control group. A 12-week home based exercise program, prescribed individually, was performed by the pelvic floor muscle training group. Urinary incontinence symptoms (Incontinence Impact Questionnaire-7, Urogenital Distress Inventory-6, bladder diary, stop test and pad test) were assessed, and the pelvic floor muscle strength was measured for (PERFECT testing, perineometric and ultrasound) all participants before and after 12 weeks of treatment. The pelvic floor muscle training group had significant improvement in their symptoms of urinary incontinence (P=0.001) and an increase in pelvic floor muscle strength (P=0.001, by the dependent t test) compared with the control group. All the symptoms of urinary incontinence were significantly decreased in the patients that had reached pelvic floor muscle strength of grade 5 and continued the pelvic floor muscle training (P<0.05). The study demonstrated that pelvic floor muscle training is effective in reducing the symptoms of stress and mixed urinary incontinence and in increasing pelvic floor muscle strength. © The Author(s) 2014.

    2004-05-01

    Full Text Available In this paper we describe the development, experiments and evaluation of the iFloor, an interactive floor prototype installed at the local central municipality library. The primary purpose of the iFloor prototype is to support and stimulate community interaction between collocated people. The context of the library demands that any user can walk up and use the prototype without any devices or prior introduction. To achieve this, the iFloor proposes innovative interaction (modes/paradigms/patterns for floor surfaces through the means of video tracking. Browsing and selecting content is done in a collaborative process and mobile phones are used for posting messages onto the floor. The iFloor highlights topics on social issues of ubiquitous computing environments in public spaces, and provides an example of how to exploit human spatial movements, positions and arrangements in interaction with computers.

    To assess the efficacy of pelvic floor physical therapy (PFPT) as primary treatment of urinary urgency and frequency symptoms We conducted a prospective cohort study of women with urinary urgency and frequency symptoms. Participants underwent PFPT once or twice per week for 10 weeks. Symptom improvement was assessed by validated questionnaires (Pelvic Floor Distress Inventory-Short Form 20 and Patient Global Impression of Improvement), voiding diaries, and subjective measures. Fifty-seven participants enrolled; 21 (36.8%) withdrew or completed less than 5 weeks of PFPT. Thirty-one (54.4%) of the remaining 36 participants completed 10 weeks of PFPT. The mean age of the study group (n = 36) was 48.9 ± 15.0 years. The primary diagnoses were overactive bladder syndrome (n = 24, 66.7%) and painful bladder syndrome (n = 12, 33.3%). Women attended a median of 14.0 (interquartile range [IQR], 8.0-16.0) PFPT visits over a median of 11.9 weeks (IQR, 10.0-18.1). At baseline, the median Pelvic Floor Distress Inventory-Short Form 20 score was 79.2 (IQR, 53.1-122.9), and decreased to 50.0 (IQR, 25.0-88.5; P therapies. The high dropout rates suggest that motivation or logistic factors may play a significant role in the utilization and success of this treatment option.

    Highlights: • Floor flexibility plays a non-negligible role in amplifying horizontal vibrations. • COV of in-floor horizontal and vertical acceleration are 0.15–0.25 and 0.25–0.55. • In-floor variation of vibrations is higher in lower floors. • Floor spectra from limited nodes underestimates vibrations by a factor of 1.5–1.75. - Abstract: Floor vibration of a reactor building subjected to seismic loads was investigated, with the aim of quantifying the variability of vibrations on each floor. A detailed 3D building model founded on the bedrock was excited simultaneously in three directions by artificial accelerograms compatible with Finnish ground response spectra. Dynamic simulation for 21 s was carried out using explicit time integration. The extracted results of the simulation were acceleration in several floor locations, transformed to pseudo-acceleration (PSA) spectra in the next stage. At first, the monitored locations on the floors were estimated by engineering judgement in order to arrive at a feasible number of floor nodes for post processing of the data. It became apparent that engineering judgment was insufficient to depict the key locations with high floor vibrations, which resulted in un-conservative vibration estimates. For this reason, a more systematic approach was later considered, in which nodes of the floors were selected with a more refined grid of 2 m. With this method, in addition to the highest PSA peaks in all directions, the full vibration distribution in each floor can be determined. A statistical evaluation of the floor responses was also carried out in order to define floor accelerations and PSAs with high confidence of non-exceedance. The conclusion was that in-floor variability can be as high as 50–60% and models with sufficiently dense node grids should be used in order to achieve a realistic estimate of floor vibration under seismic action. The effects of the shape of the input spectra, damping, and flexibility of the

    To review the literature on the origin, anatomical rationale, techniques, and evidence-based effectiveness of peripartum pelvic floor exercises (PFEs) in the prevention of pelvic floor problems including urinary and anal incontinence, and prolapse. Literature was reviewed for background information. MEDLINE, EMBASE, CINAHL, and proceedings of scientific meetings were searched for evidence-based data. A comprehensive literature search was performed to find all studies that involved the use of antepartum and/or postpartum PFEs. For the MEDLINE (1966 to 2002) and CINAHL (1980 to 2002) searches, the following key words were used: urinary incontinence (prevention and control, rehabilitation, therapy), fecal incontinence, exercise or exercise therapy, Kegel, muscle contraction, muscle tonus, muscle development, pelvic floor, pregnancy, puerperium, puerperal disorders. For the EMBASE (1980 to 2002) search, the following key words were used: micturition disorder (prevention, rehab, disease management, therapy), fecal incontinence, labour complication, pregnancy disorder, puerperal disorder, antepartum care, pregnancy, kinesiotherapy, exercise, pelvic floor, bladder. A manual search was performed of available abstracts presented at the annual scientific meetings of the International Continence Society (1997, 1999 to 2002), American Urogynecologic Association (1997 to 1998, 2000 to 2002), and International Urogynecological Association (1997, 1999 to 2002). Twelve studies evaluating the role of antepartum PFE were found, of which 3 randomized controlled trials (RCTs) comparing PFEs for the prevention of urinary incontinence to controls were included. Twelve studies evaluating postpartum PFEs for prevention of urinary incontinence were reviewed, of which 4 RCTs were included. Five studies evaluating postpartum PFEs for the prevention of anal incontinence were reviewed, of which 4 RCTs were included. Participants in the studies were primiparous women. DATA TABULATION AND

    A smart floor is demonstrated by integrating a square-frame triboelectric nanogenerator (SF-TENG) into a standard wood floor. The smart floor has two working modes based on two pairs of triboelectric materials: one is purposely chosen polytetrafluoroethylene films and aluminum (Al) balls, and the other is the floor itself and the objects that can be triboelectrically charged, such as basketball, shoe soles, and Scotch tape, etc. Utilizing the Al balls enclosed inside shallow boxes, the smart floor is capable of harvesting vibrational energy and, hence, provides a nonintrusive way to detect sudden falls in elderly people. In addition, when the basketball is bounced repeatedly on the floor, the average output voltage and current are 364 ± 43 V and 9 ± 1 μA, respectively, and 87 serially connected light-emitting diodes can be lit up simultaneously. Furthermore, the friction between the triboelectrically chargeable objects and the floor can also induce an alternating current output in the external circuit without the vibration of the Al balls. Normal human footsteps on the floor produce a voltage of 238 ± 17 V and a current of 2.4 ± 0.3 μA. Therefore, this work presents a smart floor with built-in SF-TENG without compromising the flexibility and stability of the standard wood floor and also demonstrates a way to harvest ambient energy solely by using conventional triboelectric materials in our daily life.

    Chronic pelvic pain (CPP) is a syndrome of related diagnoses including pain originating from the muscles of the pelvic floor. The objective of this study was to evaluate which muscles are important to examine, in what manner pelvic floor muscle pain contributes to patients' pain experience, or what thresholds should be applied to identify significant pelvic floor muscle pain by comparing exam findings with outcome measures A total of 428 patients meeting the definition for CPP were evaluated using a standardized physical examination of the abdominal wall, pelvic floor, and vestibule along with the 12 domain Patient Reported Outcome Measures Information System (PROMIS). These scores were evaluated for unidimensionality followed by latent profile analysis. The areas under the receiver operator characteristic curves were used to identify the best pain threshold for each muscle. The eight pelvic floor muscle sites all loaded onto a single factor, separate from other areas examined. Two latent classes were found within all the variables. Patients in the severe pelvic floor pain class had significantly worse pain related PROMIS scores. Optimal thresholds for identifying significant pelvic floor pain ranged between 3 and 5. Pain in the pelvic floor muscles is distinguishable from pain in the abdominal wall and vulva. Any of the lateral muscle sites evaluated can be used to identify patients with significant pelvic floor pain. Two latent classes of CPP patients were identified: those with limited and those with severe pain, as identified by moderate to severe pelvic floor tenderness.

    Increasing public and professional attention has recently been focused on the issue of both faecal and urinary incontinence following childbirth and these symptoms are sometimes being cited as indications for elective caesarean section. Faecal incontinence has a female-to-male preponderance of 8:1, consistent with childbirth as the principal causative factor, although most symptomatic women do not seek medical advice until after the menopause. Similarly, urinary stress incontinence is almost an exclusively female phenomenon. Obstetric injury may take the form of direct muscular damage to the anal sphincter, as occurs during a third-degree tear, and/or may be the result of cumulative damage to the pudendal nerves. Mechanical, neural and endocrine factors may all play a causative role in faecal incontinence. Symptoms are rarely volunteered by the patient, and may be present for many years after the index pregnancy, and clinical examination alone may fail to detect specific abnormalities. The performance of anal manometry, endoanal ultrasound, urodynamics and neurophysiology studies of the pelvic floor may help to increase the diagnostic yield. Treatment for both urinary and faecal incontinence is available in the form of physiotherapy, fluid and dietary manipulation and in more severe cases, surgery. Adequate primary management of third-degree tears requires careful appraisal as this injury, in particular, is the most important risk factor for subsequent faecal incontinence symptoms. In this chapter we aim to outline the mechanism of damage to the pelvic floor during childbirth, concentrating primarily on anal sphincter damage. We describe the necessary investigations, follow-up and treatment which women with significant pelvic floor damage should receive following delivery, and we finally discuss the issue of further deliveries and, specifically, the current place of caesarean section.

    Full Text Available OBJECTIVE: Prospective study to objectively evaluate the benefits of pelvic floor strengthening exercises associated to biofeedback for the treatment of stress urinary incontinence. MATERIALS AND METHODS: Fourteen patients diagnosed with stress urinary incontinence (SUI were selected for this study. All patients underwent a pelvic floor training associated to biofeedback for 12 consecutive weeks. Urodynamic tests, pad test and bladder diary were analyzed at the beginning of the study, at the end and after 3 months. The King's Health Questionnaire (KHQ was applied before and after treatment to assess the impact in the quality of life. RESULTS: There was a significant reduction in the pad weight (from 14.21 g to 1 g, number of urinary leakage episodes (from 8.14 per day to 2.57 per day and daytime frequency (from 7.93 per day to 5.85 per day. At urodynamics the authors observed a significant increase in Valsalva leak-point pressure (from 103.93 cm H2O to 139.14 cm H2O, cistometric capacity (from 249.29 mL to 336.43 mL, p = 0.0015 and bladder volume at first desire to void (from 145 mL to 215.71 mL. Those differences were kept during the first 3 months of follow up. The KHQ revealed significant differences except in the case of "general health perception", which covers health in general and not exclusively urinary incontinence. CONCLUSION: Treatment of SUI with pelvic floor exercises associated to biofeedback caused significant changes in the parameters analyzed, with maintenance of good results 3 months after treatment.

    Magnetic resonance colpocystorectography (MR-CCRG) is presented in the evaluation of patients with pelvic-floor disorders. Five healthy volunteers and 44 female patients with isolated or combined visceral descent underwent dynamic MRI and dynamic fluoroscopy (DF). MR-CCRG was performed with the patient in a supine position using a True FISP sequence (1 image/1.2 s; in-plane resolution 1.02 mm) during pelvic floor contraction, relaxation, and straining maneuvers. Relevant organs, such as urethra, bladder, vagina, and rectum, were opacified by using a saline solution, Magnevist (Schering AG, Berlin, Germany), and sonography gel, respectively. The clinical evaluation and the intraoperative results (30 cases) were used as reference. MR-CCRG and DF were non-diagnostic in 3 cases each. Most patients had a combined type of visceral prolapse, the most frequent combination being a vaginal vault prolapse and a cystocele. The points of reference were sufficiently outlined by DF and MR-CCRG. In comparison with the clinical and intraoperative results, MR-CCRG proved to be especially beneficial in the diagnosis of different types of enteroceles including a uterovaginal prolapse. MR-CCRG showed an equal or higher sensitivity and specificity for all individual sites when compared with DF. Also, predominant herniation obscuring other concomitant prolapse could be verified in 8 cases. MR-CCRG is superior to DF and accurately depicts pelvic-floor descent and prolapse in women. The possibility of dynamic presentation (see enclosed CD-ROM) allows for a better understanding of the organ movements within a given topographic reference setting. (orig.). With 5 figs., 3 tabs.

    Dynamic endoanal ultrasound has emerged in recent years as a test that could replace the now existing tests in the diagnosis of pelvic floor disorders. The aim of this paper is to determine the usefulness of echodefecography in the diagnosis and evaluation of patients with symptoms of anorrectal obstruction, and show the results obtained after its implementation in a pelvic floor unit, as a complementary tool that could replace conventional defecography. In this retrospective study we analyzed 66 patients with a mean age of 55 years (19-83), 61 women (92%). All dynamic ultrasound was performed in 3 dimensions and was correlated with symptoms and physical findings in the consultation. A descriptive and inferential study was performed to find a kappa correlation between physical examination and echodefecography. The reasons for consultation were: Anorrectal obstruction syndrome 36 patients (54.5%), pelvic organ prolapse 27 patients (40.9%), and anorrectal obstruction syndrome along with pelvic organ prolapse 3 patients (4.5%). The correlation of the 2 groups indicated that echodefecography diagnosed more patients with grade III rectocele, enteroceles, and anismus than the combination of scan-ultrasound-manometry-proctoscopy (Kappa 0.26, 0.38 and 0.21, 95% CI: from 0,07 to 1.00, 0.15 to 1.00 and from 0.12 to 1.00, respectively) (P<.001). Conversely, echodefecography diagnosed less perineal descense (Kappa 0.28, 95% CI: 0.12 to 1.00). Dynamic anal ultrasonography may have a role as a complementary test in patients with pelvic floor disorders, achieving diagnoses that would go undetected by inspection, physical examination and manometry.

    Living learning communities are collaborations between university housing and academic departments designed to enhance the overall student experience by integrating classroom/laboratory learning, student life and extracurricular activities. At Coastal Carolina University, the residential community associated with the Marine Science program is known as the Sea Floor. Students selected to become members of the Sea Floor remain "in residence" for two consecutive semesters. These students are first-time freshman that share a common course connection. This course is usually Introduction to Marine Science (MSCI 111) or MSCI 399s, which are one credit field/laboratory centered internships. The common course connection is designed so residents can establish and maintain an educational dialog with their peers. Activities designed to enhance the students' networking skills and educational and social development skills include monthly lunches with marine science faculty and dinner seminars with guest speakers from academia, industry and government. Additionally, each semester several activities outside the classroom are planned so that students can more frequently interact with themselves and their faculty and staff partners. These activities include field trips to regional aquariums, local boat trips that include water sample collection and analysis, and an alternative spring break trip to the Florida Keys to study the marine environment firsthand. The resident advisor that supervises the Sea Floor is usually a sophomore or junior marine science major. This provides the residents with daily communication and mentoring from a marine science major that is familiar with the marine science program and residence life. Assessment activities include: a university housing community living survey, student interest housing focus groups, fall to spring and fall to fall retention, and evaluation of program advisors and program activities.

    Full Text Available Schwannoma (neurilemmoma is a benign nerve sheath tumor that is composed entirely of well-differentiated Schwann cells. It is important to highlight that schwannoma is usually found in the head and neck and rarely in the oral cavity. Schwannoma is a benign tumor that originates from the Schwann cells of the peripheral nerves. They are usually asymptomatic, do not recur, and malignant transformation is rare. Here, we report a case of neurilemmoma that was located at an unusual location, i.e., floor of the mouth.

    2007-08-01

    This commentary provides an overview of the current concepts and evidence related to rehabilitative ultrasound imaging of pelvic floor (levator ani) function. As this is an emerging topic, the goal is to provide a basic understanding of ultrasound imaging applications related to levator ani function: the available quantitative and qualitative information, the limitations, as well as how ultrasound imaging can be incorporated as a form of biofeedback during rehabilitation. Furthermore, as the ability to compile and compare existing evidence depends on the degree of similarity in methodology by investigators, this commentary highlights points of consideration and provides guidelines, as well as an agenda, for future investigation.

    Using a lifespan model, this article presents new scientific findings regarding risk factors for pelvic floor disorders (PFDs), focusing on the role of childbirth in the development of single or multiple coexisting PFDs. Phase I of the model includes predisposing factors, such as genetic predisposition and race. Phase II includes inciting factors, such as obstetric events. Prolapse, urinary incontinence (UI), and fecal incontinence (FI) are more common among vaginally parous women, although the impact of vaginal delivery on risk of FI is less dramatic than prolapse and UI. Phase III includes intervening factors, such as age and obesity. Copyright © 2016 Elsevier Inc. All rights reserved.

    An important cause or maintaining factor for pain in Urological Chronic Pelvic Pain Syndrome (UCPPS) may be pelvic floor muscle (PFM) dysfunction, which may also be implicated in sexual dysfunction and influenced by psychosocial factors. Pelvic floor ultrasound is a noninvasive, reliable, and relatively simple method to assess PFM morphology and function and can be assessed by the anorectal angle (ARA) and levator plate angle (LPA). The aim of the present study was to examine PFM morphology in men with UCPPS as compared with controls and to examine the correlation with pain and psychosocial measures. Our participants were 24 men with UCPPS and 26 controls. A GE Voluson E8 ultrasound probe was placed on the perineum, and three-dimensional images were taken at rest and during PFM contraction. The main outcomes were ARA and LPA at rest and contraction. Participants also completed the National Institute of Health (NIH) Chronic Prostatitis Symptom Index, Male Sexual Health Questionnaire, State Anxiety Inventory, and Pain Catastrophizing Scale. Men with UCPPS had more acute ARAs than controls both at rest and during contraction. The two groups did not differ in LPA at rest; however, men with UCPPS had significantly more acute angles during contraction and LP excursion. Acute ARAs were positively correlated with greater pain report and sexual dysfunction. Anxiety was correlated with more acute ARAs and more obtuse LPAs. Three implications can be drawn from the findings. First, ARA at rest and during contraction as well as LP angle during contraction and LPA excursion separates men with UCPPS from controls. Second, ARA at rest and during contraction was correlated with pain and sexual dysfunction, while LPA at rest was related to anxiety. Third, pelvic floor ultrasound has the potential to be a useful and objective method of assessing PFM morphology in UCPPS. © 2011 International Society for Sexual Medicine.

    The objective of this study was to assess the performance of a semiautomated pelvic floor measurement algorithmic model on dynamic magnetic resonance imaging (MRI) images compared with manual pelvic floor measurements for pelvic organ prolapse (POP) evaluation. We examined 15 MRIs along the midsagittal view. Five reference points used for pelvic floor measurements were identified both manually and using our semiautomated measurement model. The two processes were compared in terms of accuracy and precision. The semiautomated pelvic floor measurement model provided highly consistent and accurate locations for all reference points on MRI. Results also showed that the model can identify the reference points faster than the manual-point identification process. The semiautomated pelvic floor measurement model can be used to facilitate and improve the process of pelvic floor measurements on MRI. This will enable high throughput analysis of MRI data to improve the correlation analysis with clinical outcomes and potentially improve POP assessment.

    This paper presents the results of the seismic proving tests, undertaken at Tadotsu Engineering Center of NUPEC, of three process computer systems installed on a seismic isolation floor. At first, we investigated the function and seismic input conditions required for the seismic floor isolation system. The process computer systems were installed on a large-scale floor seismically isolated in the horizontal direction. Seismic excitation tests were carried out by using the 1000 ton shaking table. The isolation performance of the floor and the functional capability of the computer systems were evaluated by the seismic vibration tests. Further, vibration analyses of the isolation floor were carried out and the design method for a process computer system combined with a seismic floor isolation system was evaluated from the test results and the analyses.

    2014-01-01

    Full Text Available Shop floor performance management is a method to ensure the effective utilization of people, processes, and equipment. Changes in the shop floor might have a positive or negative effect on production performance. Therefore, optimal shop floor operation is required to enhance shop floor performance and to ensure the long-term efficiency of the production process. This work presents a case study of a semiconductor industry. The punching department is modeled to investigate the effect of changes in the shop floor on production performance through discrete event simulation. The effects on the throughput rate, machine utilization, and labor utilization are studied by adjusting the volume of parts, number of operators, and flow pattern of parts in a series of models. Simulation results are tested and analyzed by using analysis of variance (ANOVA. The best model under changes in the shop floor is identified during the exploration of alternative scenarios.

  19. Friction between footwear and floor covered with solid particles under dry and wet conditions.

    Solid particles on the floor, both dry and wet, are common but their effects on the friction on the floor were seldom discussed in the literature. In this study, friction measurements were conducted to test the effects of particle size of solid contaminants on the friction coefficient on the floor under footwear, floor, and surface conditions. The results supported the hypothesis that particle size of solids affected the friction coefficient and the effects depended on footwear, floor, and surface conditions. On dry surfaces, solid particles resulted in friction loss when the Neolite footwear pad was used. On the other hand, solid particles provided additional friction when measured with the ethylene vinyl acetate (EVA) footwear pad. On wet surfaces, introducing solid particles made the floors more slip-resistant and such effects depended on particle size. This study provides information for better understanding of the mechanism of slipping when solid contaminants are present.

    To determine if there is evidence of levator ani atrophy in primiparous women. This was a prospective observational cohort study of 202 primiparous women recruited between November 2006 and March 2008. Translabial ultrasound volumes were obtained at 36-38 weeks' gestation and at a mean of 4.5 months postpartum. Peripartum changes in bladder neck elevation and reduction of anteroposterior hiatal diameter on pelvic floor muscle contraction (PFMC) and changes in muscle thickness were analyzed. Of the 202 participants enrolled, 158 (78%) completed the study. There was a significant reduction in bladder neck elevation (P = 0.001) and change in anteroposterior hiatal diameter (P = 0.03) on PFMC when comparing antenatal and postnatal results, the latter being significantly associated with delivery mode (P = 0.013). No significant changes were detected in muscle thickness (P = 0.76). There is a reduction in sonographic measures of pelvic floor function after childbirth, but muscle atrophy is unlikely to be a significant factor. Copyright © 2013 ISUOG.

    'Green' building materials may be defined as being made of materials and by processes that have low impact on the environment. Linoleum is an example of a sustainable 'green' building material. It is durable, easy to repair, is inherently antimicrobial, and has low-cost maintenance. Unlike most other floor coverings, linoleum has naturally occurring anti-static properties, making it easy to clean, since dust and dirt will not adhere to it. The ingredients in linoleum are linseed oil, resin, limestone, wood flour, pigments and jute, all obtainable from natural sources. Vibrant colours for the flooring are created by using organic pigments with no heavy metals such as lead or calcium which, consequently, pose no threat to the environment. Linoleum is also biodegradable. It can be put into a landfill, where it will decompose; in some parts of the world it is incinerated to produce electricity. When used as feedstock for electricity, used linoleum products have an energy content of 18.6 MJ/kg, which is equivalent to coal. As no toxic or corrosive gases are released, the need for gas purification is avoided.

    In recent years, there is an increased in floor vibration problems of structures like residential and commercial building. Vibration is defined as a serviceability issue related to the comfort of the occupant or damage equipment. Human activities are the main source of vibration in the building and it could affect the human comfort and annoyance of residents in the building when the vibration exceed the recommend level. A new building, Madrasah Tahfiz located at Yong Peng have vibration problem when load subjected on the first floor of the building. However, the limitation of vibration occurs on building is unknown. Therefore, testing is needed to determine the vibration behaviour (frequency, damping ratio and mode shape) of the building. Heel-drop with pace 2Hz was used in field measurement to obtain the vibration response. Since, the heel-drop test results would vary in light of person performance, test are carried out three time to reduce uncertainty. Natural frequency from Frequency Response Function analysis (FRF) is 17.4Hz, 16.8, 17.4Hz respectively for each test.

    This project developed a low emission, cost effective, fuel efficient, medium-duty community/transit shuttle bus that meets American's with Disabilities Act (ADA) requirements and meets National Energy Policy Act requirements (uses alternative fuel). The Low Profile chassis, which is the basis of this vehicle is configured to be fuel neutral to accommodate various alternative fuels. Demonstration of the vehicle in Yellowstone Park in summer (wheeled operation) and winter (track operation) demonstrated the feasibility and flexibility for this vehicle to provide year around operation throughout the Parks system as well as normal transit operation. The unique configuration of the chassis which provides ADA access with a simple ramp and a flat floor throughout the passenger compartment, provides maximum access for all passengers as well as maximum flexibility to configure the vehicle for each application. Because this product is derived from an existing medium duty truck chassis, the completed bus is 40-50% less expensive than existing low floor transit buses, with the reliability and durability of OEM a medium duty truck.

    To demonstrate the anatomy of the female pelvic floor and to determine the anatomic differences between normal controls and women with stress urinary incontinence, using MRI. Five healthy, young, nulliparous women and 12 with stress urinary incontinence underwent MR imaging. We obtained FSE T2-weighted axial images, 3mm thick, of the region extending from the urethroversical junction to the perineal membrane. The following parameters were determined : angle, asymmetry and signal intensity of the levator ani muscles, the distance between the urethra and symphysis, and the presence, shape and angulation of urethropelvic ligament. In contrast to normal controls, frequent findings in women with stress incontinence were as follows : increased angle (43%), asymmetry (43%) and higher signal intensity (67%) of the levator ani muscles; increased distance between the urethra and symphysis; loss (43%), discontinuity (60%) and dorsal angulation (43%) of the urethropelvic ligament. In women with stress urinary incontinence, MRI clearly demonstrates the anatomy of the female pelvic floor, changes in the levator ani muscles, the distance between the urethra and symphysis, and the urethropelvic ligament. The modality can therefore be used to evaluate the anatomical changes occurring in cases of stress urinary incontinence. (author)

    To explore the role of sensory nerve impairment in women with pelvic organ prolapse, painful bladder syndrome, urinary and fecal incontinence, and sexual dysfunction. Medline and Embase were searched for articles in which sensory testing, either quantitative sensory testing or current perception thresholds, had been used to evaluate women with pelvic organ prolapse, stress and urge urinary incontinence, fecal incontinence and female sexual dysfunction. All search terms were expanded within each database prior to searching. Research to date has included small numbers of participants, used poorly matched controls, lacked a systemic sensory examination and applied non-standardized sensory testing techniques. However, the evidence suggests women with pelvic organ prolapse demonstrate sensory dysfunction. The role of sensory impairment in stress urinary incontinence is inconclusive. In women with urge urinary incontinence there is some evidence to suggest it may be urethrally mediated. Women with painful bladder syndrome may have more sensitive nerve endings which are unable to ignore repeated stimuli. Sensory impairment is common in women with sexual dysfunction, typically involving larger nerve fibres. There were no studies evaluating sensory function in women with fecal incontinence. Current evidence suggests women with pelvic floor dysfunction demonstrate sensory impairment though the causes remain unclear. Further studies are needed to investigate the different conditions of pelvic floor dysfunction using standardized sensory testing techniques, as well as evaluate the timing and mechanism by which any sensory impairment develops.

    Efforts have to be taken to ensure efficient waste management system in shop floors, with minimum utilization of space and energy when it comes to disposing metal chips formed during machining processes. The salvaging of junk metallic chips and the us e of scrap are important for the economic production of a steelworks. For this purpose, we have fabricated a metal chip compaction machine, which can compact the metal chips into small briquettes. The project started with the survey of chips formed in shop floors and the practices involved in waste management. Study was done on the requirements for a better compaction. The heating chamber was designed taking into consideration the temperature required for an easy compaction of the metal chips. The power source for compaction and the pneumatic design for mechanism was done following the appropriate calculations regarding the air pressure provided and thrust required. The processes were tested under different conditions and found effective. The fabrication of the machine has been explained in detail and the results have been discussed.

    Floor-sitting is culturally relevant to the Indian context. The present study aimed to examine the effect of age and activity on the movement patterns used and time taken to perform floor-sitting in Indian adults. Video-recordings of 30 young (23.30 ± 2.53 years) and 30 older (69.67 ± 6.45 years) adults performing floor-sitting without and with an activity (simulated feeding) were analyzed using the Floor-sitting Movement Analysis Proforma (FMAP) developed for the study. For inter-rater reliability of the FMAP, two raters analyzed the performance of a random sample of 20 participants. An almost perfect inter-rater agreeability (κ ≥ .8) was obtained for the FMAP. Cross-legged sitting was the most preferred (95%) floor-sitting position. Older adults used more number of movement components, asymmetrical patterns, more support, and more time (p sitting (p = .004). The study establishes the influence of age and activity on performance of floor-sitting. Older adults use lower developmental movement patterns that may be a "normal" adaptation to age-related sensorimotor changes. Retraining of floor-sitting is a "culturally" desired goal among Indian adults and should involve the practice of age-appropriate movement patterns in the context of meaningful activities.

    The mechanical properties of the floors used by dancers have often been suggested to be associated with injury, yet limited etiological evidence is available to support this hypothesis. The dance floors at three theatres regularly used by a touring professional ballet company were mechanically quantified with the aim of comparing floor properties with injury incidence in dancers. Cross sectional. Test points on the floors were quantified in accordance with European Sports Surface Standard protocols for force reduction. Injuries and associated variables occurring within the ballet company dancers during activity on the three floors were recorded by the company's medical staff. An injury was recorded if a dancer experienced an incident that restricted the dancer from performing all normal training or performance activities for a 24 h period. Injuries were delimited to those occurring in the lower limbs or lumbar region during non-lifting tasks. Floor construction varied between venues and a range of floor mechanical properties were observed. None of the floors complied with the range of force reduction values required by the European Sport Surface Standards. The highest injury rate was observed on the floor with the greatest variability of force reduction magnitudes. No difference in injury frequency was observed between the venues with the highest and lowest mean force reduction magnitudes. Professional dancers can be required to perform on floors that may be inadequate for safe dance practice. Intra-floor force reduction variability may have a stronger association with injury risk than mean floor force reduction magnitude. Copyright © 2013 Sports Medicine Australia.

    To investigate morphological and functional changes after pelvic floor muscle training in women with pelvic organ prolapse. This randomized controlled trial was conducted at a university hospital and a physical therapy clinic. One hundred nine women with pelvic organ prolapse stages I, II, and III were randomly allocated by a computer-generated random number system to pelvic floor muscle training (n=59) or control (n=50). Both groups received lifestyle advice and learned to contract the pelvic floor muscles before and during increases in intraabdominal pressure. In addition the pelvic floor muscle training group did individual strength training with a physical therapist and daily home exercise for 6 months. Primary outcome measures were pelvic floor muscle (pubovisceral muscle) thickness, levator hiatus area, pubovisceral muscle length at rest and Valsalva, and resting position of bladder and rectum, measured by three-dimensional ultrasonography. Seventy-nine percent of women in the pelvic floor muscle training group adhered to at least 80% of the training protocol. Compared with women in the control group, women in the pelvic floor muscle training group increased muscle thickness (difference between groups: 1.9 mm, 95% confidence interval [CI] 1.1-2.7, Ppelvic floor muscle stiffness. Supervised pelvic floor muscle training can increase muscle volume, close the levator hiatus, shorten muscle length, and elevate the resting position of the bladder and rectum. www.clinicaltrials.gov, NCT00271297.

    Full Text Available With the development of renewable energy, energy substitution technology has been applied to many fields. This research suggests that solar energy, as renewable energy, takes the place of conventional energy: a floor radiant heating system driven by solar energy is combined with a photovoltaic floor radiant heating system, and the photothermal floor radiant heating system has been proposed and investigated in this study. This research also designs a fuzzy PID (Proportion, Integration, Differentiation control system to control the indoor temperature within the set range precisely. In this paper, the proposed floor radiant heating system has been tested and analyzed. The experimental results show that the inhomogeneity of the indoor floor surface temperature distribution is larger than that of other places, and the standard deviation of the indoor floor surface temperature can reach 1.87 °C. The standard deviation was approximately 0.36 °C at 0.6 m, 1.2 m and 1.8 m, which indicates this is suitable for habitation. Three kinds of floor radiant heating systems were compared and analyzed to demonstrate the advantage of the proposed floor radiant heating system. The calculation method of the heating system was proposed and applied to the actual heating system in this paper. The proposed floor radiant heating system is a highly efficient and environmental protection system that can be used for heating extensive areas to realize the objective of energy saving and emission reduction.

    Full Text Available Farmed blue foxes (Vulpes lagopus are traditionally housed on mesh floors where they are unable to perform certain species-specific behaviours, such as digging, which may compromise the animals' welfare. This study describes how a possibility to use in-cage sand floor affects welfare-related variables like growth of the claws, adrenal cortex function, and fur properties in juvenile blue foxes. The foxes (N=32 were housed in male-female sibling pairs in an outdoor fur animal shed in cage systems consisting of two traditional fox cages. For the eight male-female sibling pairs of the Control group, there was a mesh floor in both cages of each cage system, whereas for the eight pairs of the Sand group there was a mesh floor in one cage and a 30–40 cm deep earth floor in the other cage. The results show that sand floor is beneficial for the wearing of the claws of foxes. Furthermore, an early experience of sand floor may have positive effects on the foxes' fur development. The results, however, also suggest that there might appear welfare problems observed as disturbed claw growth and increased adrenal cortex activation if foxes that are once provided with clean and unfrozen sand floor are not allowed to enjoy this floor all the time.

    The anatomy of the pelvic floor is complex and clinical examination alone is often insufficient to diagnose and assess pathology. With a greater understanding of pelvic floor dysfunction and treatment options, imaging is becoming increasingly common. This review compares three imaging techniques. Ultrasound has the potential for dynamic assessment of the entire pelvic floor. Magnetic resonance imaging is able to rapidly image the entire pelvic floor but it is expensive and tends to underestimate pathology. Dynamic defaecating proctography or cystocolpoproctography is the current gold standard for posterior compartment imaging but requires opacification of the bladder to provide a global view.

    The prevalence, cost and disability associated with lumbopelvic pain continues to rise despite the range of available therapeutic interventions, indicating a deficiency in current approaches. A literature base highlighting a correlation between lumbopelvic pain and pelvic floor function is developing; however, the features that characterize this correlation have yet to be fully established. The purpose of this study was to determine the prevalence and characteristics of pelvic floor muscle function among women with lumbopelvic pain. A cross-sectional study was conducted on non-pregnant women presenting with lumbopelvic pain to one of seven outpatient orthopaedic clinics in Canada. Potential participants underwent a screening process to assess for pelvic floor muscle dysfunction. A total of 182 women were recruited and 97 were excluded, leaving 85 participants (n = 85). Of these, 95.3% were determined to have some form of pelvic floor dysfunction. Specifically, 71% of the participants had pelvic floor muscle tenderness, 66% had pelvic floor weakness and 41% were found to have a pelvic organ prolapse. Participants with combined low back pain and pelvic girdle pain presented with higher levels of disability and increased characteristics of pelvic floor dysfunction. Our findings corroborate and extend recent research supporting the hypothesis that a high proportion of pelvic floor muscle dysfunction is present among women with lumbopelvic pain. Specifically, increased pelvic floor muscle pressure-pain sensitivity represented the most frequent characteristic, the clinical implications of which require further study.

    The aim of the study was to evaluate the effects of a 6-week sEMG-biofeedback-assisted pelvic floor muscle training program on pelvic floor muscle activity in young continent women. Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Biofeedback training was continued for 6 weeks, 3 times a week. Muscle strenghtening and endurance exercises were performed alternately. SEMG (surface electromyography) measurements were recorded on four different occasions: before training started, after the third week of training, after the sixth week of training, and one month after training ended. A 6-week sEMG-biofeedback-assisted pelvic floor muscle training program significantly decreased the resting activity of the pelvic floor muscles in supine lying and standing. The ability to relax the pelvic floor muscles after a sustained 60-second contraction improved significantly after the 6-week training in both positions. SEMG-biofeedback training program did not seem to affect the activity of the pelvic floor muscles or muscle fatigue during voluntary pelvic floor muscle contractions. SEMG-biofeedback-assisted pelvic floor muscle training might be recommended for physiotherapists to improve the effectiveness of their relaxation techniques.

    The aim of the current study was to evaluate the effect of pelvic floor muscle training in men with poststroke lower urinary tract symptoms. Thirty-one poststroke men, median age 68 years, were included in this single-blinded randomized controlled trial. Thirty participants, 15 in each group......, completed the study. The intervention consisted of 3 months (12 weekly sessions) of pelvic floor muscle training in groups and home exercises. The effect was evaluated by the DAN-PSS-1 (Danish Prostate Symptom Score) questionnaire, a voiding diary, and digital anal palpation of the pelvic floor muscle...... statistically significantly in pelvic floor muscle function (p

    Background. Increasingly more people live in tall buildings and on higher floor levels. Factors relating to floor level may protect against or cause cardiovascular disease (CVD). Only one previous study has investigated the association between floor level and CVD. Methods. We studied associations between floor of bedroom and self-reported history of stroke, venous thromboembolism (VTE), and intermittent claudication (IC) among 12.525 inhabitants in Oslo, Norway. We fitted multivariate logistic regression models and adjusted for sociodemographic variables, socioeconomic status (SES), and health behaviors. Additionally, we investigated block apartment residents ( N = 5.374) separately. Results. Trend analyses showed that disease prevalence increased by floor level, for all three outcomes. When we investigated block apartment residents alone, the trends disappeared, but one association remained: higher odds of VTE history on 6th floor or higher, compared to basement and 1st floor (OR: 1.504; 95% CI: 1.007-2.247). Conclusion. Floor level is positively associated with CVD, in Oslo. The best-supported explanation may be residual confounding by building height and SES. Another explanation, about the impact of atmospheric electricity, is also presented. The results underline a need to better understand the associations between residence floor level and CVD and multistory housing and CVD.
