ABSTRACT Aim : To assess the cleaning efficacy of manual and automated instrumentation using 4% sodium hypochlorite singly and in combination with Glyde file Prep as root canal irrigant. Methodology : The study utilized 40 extracted human permanent premolars with single, straight and fully formed root. The teeth were then divided into four groups of ten each, Group I and II were prepared by manual instruments with 4% sodium hypochlorite used as irrigant singly [Group I] or in combination with Glyde file prep. Group III and IV were prepared by automated instruments at 250 rpm with 4% sodium hypochlorite as irrigant singly [Group III] and in combination with glyde file prep [Group IV] automated instrumentation. After completion of the root canal preparation the canal, teeth were prepared for SEM examination. These photomicrographs were qualitatively evaluated using criteria. Overall cleanliness, presence or absence of the smear layer, presence or absence of the debris, patency of the opening of dentinal tubules. Results : When comparing the cleansing efficacy of manual and automated instrumentation using 4% sodium hypochlorite better cleansing was there with manual instrumentation. When comparing the cleansing efficacy of manual and automated instrumentation using combination regime cleansing is better with automated instrumentation. When comparing the cleansing efficacy of manual instrumentation using 4% sodium hypochlorite singly and in combination with EDTA, the combination regime led to better cleansing. When comparing the cleansing efficacy of automated instrumentation using 4% sodium hypochlorite singly and in combination regime lead to better cleansing. Conclusion : Neither of instrumentation technique, nor irrigating regimes were capable of providing a completely clean canal. Automated instrumentation with a combination of sodium hypochlorite & EDTA resulted the best cleansing efficacy. PMID:27616839

Abstract Background and Aim: Low-volume polyethylene glycol with ascorbic acid (PEG-Asc) use is reported to be as safe and effective as traditional 4-L polyethylene glycol use. However, PEG-Asc produces bubbles, which cause problems during colonoscopy. Data on the effects of using antifoaming agents such as simethicone with PEG-Asc are lacking. The aim of this CONSORT-prospective, randomized, observer-blinded, controlled trial is to compare the quality of bowel preparation and compliance between PEG-Asc users and PEG-Asc plus simethicone users. Methods: Adult outpatients aged 18 to 80 years undergoing colonoscopy were recruited to the study. Two hundred sixty patients were randomly assigned to 1 of 2 treatment arms, PEG-Asc or PEG-Asc plus simethicone. The primary outcome measure was the bowel cleansing quality using Boston bowel preparation scale and bubble scores. The secondary outcome measures were patient tolerability and doctor tolerability. Results: The simethicone group showed superior cleansing results (6–9 Boston scale scores: 99% vs. 84%, <5% bubble scores: 96% vs. 49%, P < 0.001) and fewer gastrointestinal symptoms (abdominal fullness: 24% vs. 55%, colicky pain: 5% vs. 24%, P < 0.001) than the non-simethicone group. Moreover, endoscopist fatigue during colonoscopy was lower in the simethicone group than in the non-simethicone group (1.31 ± 0.75 vs. 2.97 ± 2.14, P < 0.001). Conclusion: PEG-Asc plus simethicone use was more effective and associated with better patient and endoscopist tolerance than PEG-Asc use. Therefore, this combination is recommended as one of the promising methods for bowel preparation before colonoscopy. PMID:27428209

Successful colonoscopies require good bowel preparations-poor bowel preparations can increase medical costs, rates of missed lesions, and procedure duration. The combination of polyethylene glycol (PEG) 3350 without electrolytes (MiraLAX; Schering-Plough Healthcare Products, Inc, Kenilworth, NJ) and 64 oz of Gatorade (PepsiCo, Inc, Purchase, NY) has gained popularity as a bowel preparation regimen. However, the efficacy and tolerability of this approach has not been compared with standard bowel preparations in clinical trials. We compared split-dose (PEG) 3350 with electrolytes (GoLytely; Braintree Laboratories, Inc, Braintree, MA) with split-dose MiraLAX alone and in combination with pretreatment medications (bisacodyl or lubiprostone) to determine the efficacy and patient tolerability of MiraLAX as an agent for bowel preparation. We performed a prospective, randomized, blinded, controlled trial at a tertiary care center. Patients (n=403) were randomly assigned to groups given GoLytely, MiraLAX, MiraLAX with bisacodyl (10 mg), or MiraLAX with lubiprostone (24 μg). MiraLAX was combined with 64 oz of Gatorade. All patients were surveyed regarding preparation satisfaction and tolerability. The Ottawa bowel preparation scale was used to grade colon cleanliness. GoLytely was more effective at bowel cleansing (average Ottawa score, 5.1) than MiraLAX alone (average Ottawa score, 6.9) or in combination with lubiprostone (average Ottawa score, 6.8), or bisacodyl (average Ottawa score, 6.3) (P<.001). MiraLAX was associated with a trend toward longer procedure duration (P=.096). Groups given MiraLAX rated the overall experience as more satisfactory than those given GoLytely (P<.001). There were no differences between polyp detection rates (P=.346) or adverse events (P=.823). Split-dose MiraLAX in 64 oz of Gatorade is not as effective as 4 L split-dose GoLytely in bowel cleansing for screening colonoscopies. Copyright © 2011 AGA Institute. Published by Elsevier Inc.

Many patients report discomfort because of the unpleasant taste of bowel preparation solutions. This study aimed to determine whether adding orange juice to 2 L of polyethylene glycol plus ascorbic acid is effective for reducing patient discomfort and improving palatability during bowel preparation. This was a single-blinded, randomized controlled trial. The study was conducted at a tertiary referral hospital and a generalized hospital. Consecutive outpatients and inpatients were randomly allocated to drink 2 L of polyethylene glycol-ascorbic acid or 2 L of polyethylene glycol-ascorbic acid with orange juice in a single dose or a split dose. Tolerability, palatability score, willingness, and related adverse events were investigated by questionnaires. Bowel cleansing was rated using the Aronchick scale. Each score was graded on a 5-point scale. A total of 107 patients, 53 in the orange juice group and 54 in the polyethylene glycol-ascorbic acid group who underwent elective colonoscopy were enrolled. The palatability score (mean ± SD) was higher in the orange juice group than in the control group (2.36 ± 0.76 vs 1.78 ± 0.88; p = 0.005). Nausea was less frequent in the orange juice group (26.4% vs 59.3%; p = 0.001). Total amount of bowel preparation ingested was not significantly different between the groups (p = 0.44). The bowel preparation score (mean ± SD) was not significantly different (1.49 ± 0.80 vs 1.43 ± 0.77; p = 0.94). Willingness to repeat the same process was higher in the orange juice group (90.4% vs 66.7%; p = 0.003). This study is limited because only ambulatory patients were enrolled. Orange juice intake before drinking 2 L of polyethylene glycol-ascorbic acid for colonoscopy can reduce patient discomfort, resulting in improved acceptability and patient compliance. This method is as effective for bowel cleansing as polyethylene glycol.

In gastroenterology a sufficient colon cleansing improves adenoma detection rate and prevents the need for preterm repeat colonoscopies due to invalid preparation. It has been shown that patient education is of major importance for improvement of colon cleansing. Objective of this study was to assess the function of an automated text messaging (short message service, SMS)-supported colonoscopy preparation starting 4 days before colonoscopy appointment. After preevaluation to assess mobile phone usage in the patient population for relevance of this approach, a Web-based, automated SMS text messaging system was developed, following which a single-center feasibility study at a tertiary care center was performed. Patients scheduled for outpatient colonoscopy were invited to participate. Patients enrolled in the study group received automated information about dietary recommendations and bowel cleansing during colonoscopy preparation. Data of outpatient colonoscopies with regular preparation procedure were used for pair matching and served as control. Primary end point was feasibility of SMS text messaging support in colonoscopy preparation assessed as stable and satisfactory function of the system. Secondary end points were quality of bowel preparation according to the Boston Bowel Preparation Scale (BBPS) and patient satisfaction with SMS text messaging-provided information assessed by a questionnaire. Web-based SMS text messaging-supported colonoscopy preparation was successful and feasible in 19 of 20 patients. Mean (standard error of the mean, SEM) total BBPS score was slightly higher in the SMS group than in the control group (7.3, SEM 0.3 vs 6.4, SEM 0.2) and for each colonic region (left, transverse, and right colon). Patient satisfaction regarding SMS text messaging-based information was high. Using SMS for colonoscopy preparation with 4 days' guidance including dietary recommendation is a new approach to improve colonoscopy preparation. Quality of colonoscopy preparation was sufficient and patients were highly satisfied with the system during colonoscopy preparation.

The pH at the surface of healthy human skin is around 5. Cleansing the skin with soap increases the pH of the skin, which then returns to a more acidic pH within a few hours. However, the effects of skin cleansing with soap over a long time on the pH regulatory system is still unclear. We compared the pH of the skin between users of a soap-based cleanser and of a mild-acidic cleanser prior to and following the cleansing. This study had two groups of subjects, one group who had used a soap-based cleanser for more than 5 years and the other group who had used a mild-acidic cleanser for more than 5 years. The pH on the inner forearm of each subject was measured prior to and for 6 h after cleansing with a soap bar. There were no differences between the pH of the skin these two groups prior to cleansing, immediately after cleansing or in the pH recovery rate for 6 h. These results suggest that long-term continuous use of a soap-based cleanser does not affect the pH-maintaining mechanism of human skin. © 2014 John Wiley & Sons A/S.

4-L polyethylene glycol preparations are effective for colon cleansing before colonoscopy. However, large volume and unpleasant taste reduce tolerability and acceptability limiting patient compliance. A new isosmotic low-volume polyethylene glycol preparation with citrates and simethicone plus bisacodyl has been developed to improve patient compliance and tolerability. To compare the efficacy of 2 different regimens of preparation vs a split-dose of polyethylene glycol solution. In this randomised, blinded, comparative study, 153 patients were allocated to 3 arms. Arm 1 (n=52) received bisacodyl and 2-L polyethylene glycol with citrates and simethicone the day before the procedure. Arm 2 (n=50) received bisacodyl the day before and 2-L polyethylene glycol with citrates and simethicone on the day of colonoscopy. Control group (n=51) received a split-dose of 4-L polyethylene glycol. Cleansing was evaluated according to Ottawa scale. The mean Ottawa score was not different in the 3 groups. Excellent cleansing was observed more frequently in arm 2 (70%) than in controls (49%) (p<0.05). No serious adverse events were observed in the 3 regimens. The willingness to repeat the same bowel preparation was superior in arms 1 and 2 than in controls (p<0.001). New low-volume preparations seem to be as effective as the split 4-L polyethylene glycol regimen, showing a better tolerability and acceptability. Copyright © 2012. Published by Elsevier Ltd.

This document was originally published in 1997 as a International Space University Master of Space Studies student's project. While the specifics may be a little dated, the results gleaned are still relevant and valid. Johnson Space Center is now abuzz with preparations for the International Space Station. The work on the various systems for the U.S. Habitation Module will begin in 1998. As a prelude, the Flight Crew Support Division perceived the need to take a closer, more critical took at planning the Whole Body Cleansing function for ISS. This report is an endeavour to retrieve all data available on whole body cleansing mechanisms used, past and present, by the Russians and the Americans, analyze it and create design concepts for products/product systems for zero-g whole body cleansing on ISS Alpha, for typical duration of about 90 days. This report takes a close look at the Skylab collapsible shower, the Mir shower/sauna, the full body cleansing methods currently in use onboard the Space Shuttle and Mir and at the Whole Body Shower designed and tested for Space Station Freedom. It attempts to "listen" carefully to what the Mir astronauts (Norm Thagard, Shannon Lucid and John Blaha) have to say about their personal hygiene experiences during their recent stays on Mir. The findings in the report call for a change in paradigm. What is good for Earth conditions is not necessarily good for Zero-g! It concludes that a shower is not a good idea for the ISS. The final concept that is proposed reflects very strongly what the Mir astronauts would like to have and to use onboard a station like the ISS, The report concludes with directions of how to take the "idea" further and realize it in the form of a product system for Whole Body Cleansing onboard the ISS.

Purpose Bowel cleansing is generally regarded as time-consuming and unpleasant among patients. Patients commonly state that bowel preparation provokes more discomfort than the actual colonoscopic examination. The purpose of this study was to compare two regimens of sodium phosphate (NaP) tablets versus polyethylene glycol (PEG) solution for bowel preparation in healthy Korean adults. Materials and Methods This was a single center, prospective, open-label, investigator-blinded, randomized, controlled-pilot study. A total of 62 healthy Korean subjects were randomly assigned to two groups (NaP vs. PEG). Efficacy, safety, and patient-related outcomes, as well as procedural parameters, were evaluated. Results Although there were no significant differences in total Ottawa bowel quality score, fluid scores and the rate of adequate bowel preparation were significantly better in the NaP group than the PEG group. Additionally, the NaP group showed better results regarding patient tolerance, satisfaction, preference, and rate of adverse events than the PEG group. Significant fluctuations in specific serum electrolytes were common and of a greater magnitude in the NaP group than the PEG group. However, these abnormalities were transient and did not result in serious complications and side effects. Conclusion In this study, NaP tablets were shown to be an effective, well-tolerated, and acceptable regimen for bowel preparation. Also, our study suggests that NaP tablets may be safe and can be used as a bowel cleansing agent in healthy adults undergoing elective colonoscopy. Further multicenter, large scale studies are needed to confirm these findings. PMID:25323890

Four liters or more of orally taken polyethylene glycol solution (PEG) has proved to be an effective large-bowel cleansing method prior to colonoscopy. The problem has been the large volume of fluid and its taste, which is unacceptable to some examinees. We aimed to investigate the effectiveness of 2 l PEG combined with senna compared with 4 l PEG for bowel preparation. The design was a single-center, prospective, randomized, investigator-blinded study with parallel assignment, in the setting of the Endoscopy Unit of Umeå University Hospital. Outpatients (n = 490) scheduled for colonoscopy were enrolled. The standard-volume arm received 4 l PEG, and the low-volume arm received 36 mg senna glycosides in tablets and 2 l PEG. The cleansing result (primary endpoint) was assessed by the endoscopist using the Ottawa score. The patients rated the subjective grade of ease of taking the bowel preparation. Analysis was on an intention-to-treat basis. There were significantly more cases with poor or inadequate bowel cleansing after the low-volume alternative with senna and 2 l PEG (22/203) compared with after 4 l PEG (8/196, p = 0.027). The low-volume alternative was better tolerated by the examinees: 119/231 rated the treatment as easy to take compared with 88/238 in the 4 l PEG arm (p = 0.001). 4 l PEG treatment is better than 36 mg senna and 2 l PEG as routine colonic cleansing before colonoscopy because of fewer failures.

Many protocols of bowel preparation are available for use in children; however, none of them is commonly accepted. The aim of the study was to evaluate the efficacy and acceptability of high-volume polyethylene glycol (PEG) versus low-volume PEG combined with bisacodyl (BPEG) versus sennosides for colonoscopy preparation in children. Participants ages 10 to 18 years were randomly assigned to receive either PEG 60 or PEG 30 mL kg⁻¹ day⁻¹ plus oral bisacodyl 10 to 15 mg/day or sennosides 2 mg kg⁻¹ day⁻¹ for 2 days. A blinded assessment of bowel cleansing was made by the endoscopist according to the Aronchick and Ottawa scales. Patient acceptability was evaluated with the visual-analog scale. Analysis was done on an available case analysis basis. Of 240 patients enrolled in the study 234 patients were available for analysis of the efficacy of colon cleansing. There were no significant differences found among the 3 groups for the proportions of participants with excellent/good (PEG: 35/79, BPEG: 26/79, sennosides 25/76) and poor/inadequate (PEG: 20/79, BPEG: 28/79, sennosides 28/76) bowel preparation evaluated with the Aronchick scale and for the mean Ottawa total score (PEG: 5.47 ± 3.63, BPEG: 6.22 ± 3.3, sennosides: 6.18 ± 3.53). Acceptability of bowel cleansing protocol was similar in all of the groups (P = 0.8). All 3 cleansing methods showed similar efficacy and tolerability; however, none of them was satisfactory.

Chronic constipation is a risk factor of inadequate bowel preparation for colonoscopy; however, no large clinical trials have been performed in this subgroup of patients. To compare bowel cleansing efficacy, tolerability and acceptability of 2-L polyethylene-glycol-citrate-simethicone (PEG-CS) plus 2-day bisacodyl (reinforced regimen) vs. 4-L PEG in patients with chronic constipation undergoing colonoscopy. Randomized, observer-blind, parallel group study. Adult outpatients undergoing colonoscopy were randomly allocated to 2-L PEG-CS/bisacodyl or 4-L PEG, taken as split regimens before colonoscopy. Quality of bowel preparation was assessed by the Ottawa Bowel Cleansing Scale (OBCS). The amount of foam/bubble interfering with colonic visualization was also measured. 400 patients were enrolled. There was no significant difference in successful cleansing (OBCS score ≤6): 80.2% in the 2-L PEG-CS/bisacodyl vs. 81.4% in the 4-L PEG group. Significantly more patients taking 2L PEG-CS/bisacodyl showed no or minimal foam/bubbles in all colonic segments (80% vs. 63%; p<0.001). 2-L PEG-CS/bisacodyl was significantly more acceptable for ease of administration (p<0.001), willingness to repeat (p<0.001) and showed better compliance (p=0.002). Split 2-L PEG-CS plus bisacodyl was not superior to split 4-L PEG for colonoscopy bowel cleansing in patients with chronic constipation; however, it performed better than the standard regimen in terms of colonic mucosa visualization, patient acceptance and compliance.

Use of the cytosensor microphysiometer to predict results of a 21-day cumulative irritation patch test in humans.

The cytosensor microphysiometer (mu phi) was investigated as a rapid, relatively inexpensive test to predict performance of skin cleansing wipes on the human 21-day cumulative irritation patch test (21CIPT). It indirectly measures metabolic rate changes in L929 cells as a function of test article dose, by measuring the acidification rate in a low-buffer medium. The dose producing a 50% reduction in metabolic rate (MRD50), relative to the baseline rate, is used as a measure of toxicity. The acute toxicity of the mu phi assay can be compared to the chronic toxicity of the 21CIPT, which is based largely on the exposure of test agents to the epidermal cells, resulting in damage and penetration of the stratum corneum leading to cell toxicity. Two series of surfactant-based cleansing wipe products were tested via the mu phi assay and 21CIPT. The first series, consisting of 20 products, was used to determine a prediction model. The second series of 38 products consisted of routine product development formulas or marketed products. Comparing the results from both tests, samples with an MRD50 greater than 50 mg/ml provided a 21CIPT score consistent with a product that performs satisfactorily in the market. When the MRD50 was greater than 78 mg/ml, the 21CIPT score was usually zero. The mu phi may be more sensitive than the 21CIPT for ranking minimally irritating materials. The mu phi assay is useful as a screen for predicting the performance of a wet wipes formula on the 21CIPT, and concurrently reduces the use of animals for safety testing in a product development program for cleansing wipes.

To investigate the efficacy and safety of premedication with simethicone/Pronase during esophagogastroduodenoscopy (EGD) with sedation. Six hundred and ten patients were randomly allocated to two groups based on type of premedication given. Premedication used in the control group was 10 mL lidocaine hydrochloride mucilage (LHM, N = 314) and premedication used in the intervention group was 80 mL simethicone/Pronase solution plus 10 mL lidocaine hydrochloride mucilage (SP/LHM, N = 296). EGD was done under sedation. Visibility scores, number of mucosal areas that needed cleansing, water consumption for cleansing, time taken for examination, diminutive lesions, pathological diagnosis, patients' gag reflex and oxygenation (pulse oximetry) were recorded. SP/LHM has significantly lower total visibility score than LHM (7.978 ± 1.526 vs 6.348 ± 1.097, P < 0.01). During the procedure, number of intragastric areas that needed cleansing and amount of water consumed were significantly less in the SP/LHM than in the LHM group (P < 0.01). In SP/LHM (P = 0.01), endoscopy procedure duration was significantly longer. Although there was no significant difference in rate of detection of diminutive lesions between LHM and SP/LHM, the endoscopist carried out more biopsies in SP/LHM. This led to a higher rate of diagnosis of atrophic gastritis (P = 0.014) and intestinal metaplasia (P = 0.024). There was no significant difference in gag reflex (P = 0.604) and oxygenation during the endoscopy procedure for either group of patients. Routine use of premedication with simethicone/Pronase should be recommended during EGD with sedation. © 2017 Japan Gastroenterological Endoscopy Society.

To identify an easy bowel preparation method for colonoscopy, we evaluated three different bowel preparation regimens regarding their efficacy and patient satisfaction. Methods In this randomized, comparative study, 892 patients who visited a secondary referral hospital for a colonoscopy between November 2012 and February 2013 were enrolled. Three regimens were evaluated: three packets of sodium picosulfate/magnesium citrate (PICO, group A), two packets of PICO with 1 L of PEG (PICO + PEG 1 L, group B), and two packets of PICO with 2 L of PEG (PICO + PEG 2 L, group C). A questionnaire survey regarding the patients' preference for the bowel preparation regimen and satisfaction was conducted before the colonoscopies. The quality of bowel cleansing was scored by the colonoscopists who used the Aronchick scoring scale and the Ottawa scale. Results The patients' satisfaction rate regarding the regimens were 72% in group A, 64% in group B, and 45.9% in group C. Nausea and abdominal bloating caused by the regimens were more frequent in group C than in group A or group B (P < 0.01). Group C showed the lowest preference rate compared to the other groups (P < 0.01). Group C showed better right colon cleansing efficacy than group A or group B. Conclusion Group A exhibited a better result than group B or group C in patient satisfaction and preference. In the cleansing quality, no difference was noted between groups A and C. PMID:25360429

A system concept for an inflight utensil/hand cleansing fixture is described which includes the following features: (1) capability for efficient cleansing and rinsing of utensils or hands, and (2) provision for general waste fluid disposal. The design concept provides for the capability of functioning for a 30 day shuttle mission containing seven occupants/users. The long range goal is to provide a functioning system capable of operating for missions of at least 120 days. The fixture is a self-contained unit that can be installed in the standard water interface requirements. Service to the unit is a single source of unheated potable water and water is discharged from the unit into a single return waste connection. In addition, the design includes provisions for the intake and discharge of purge air and the discharge of evolved gases. Both the air and the gases are filtered or processed in the assembly before releasing them into the habitability area.

Purpose: To evaluate the performance of a computer-aided detection (CAD) system for detecting colonic polyps at noncathartic computed tomography colonography (CTC) in conjunction with an automated image-based colon cleansing algorithm. Methods: An automated colon cleansing algorithm was designed to detect and subtract tagged-stool, accounting for heterogeneity and poor tagging, to be used in conjunction with a colon CAD system. The method is locally adaptive and combines intensity, shape, and texture analysis with probabilistic optimization. CTC data from cathartic-free bowel preparation were acquired for testing and training the parameters. Patients underwent various colonic preparations with barium or Gastroview in divided dosesmore » over 48 h before scanning. No laxatives were administered and no dietary modifications were required. Cases were selected from a polyp-enriched cohort and included scans in which at least 90% of the solid stool was visually estimated to be tagged and each colonic segment was distended in either the prone or supine view. The CAD system was run comparatively with and without the stool subtraction algorithm. Results: The dataset comprised 38 CTC scans from prone and/or supine scans of 19 patients containing 44 polyps larger than 10 mm (22 unique polyps, if matched between prone and supine scans). The results are robust on fine details around folds, thin-stool linings on the colonic wall, near polyps and in large fluid/stool pools. The sensitivity of the CAD system is 70.5% per polyp at a rate of 5.75 false positives/scan without using the stool subtraction module. This detection improved significantly (p = 0.009) after automated colon cleansing on cathartic-free data to 86.4% true positive rate at 5.75 false positives/scan. Conclusions: An automated image-based colon cleansing algorithm designed to overcome the challenges of the noncathartic colon significantly improves the sensitivity of colon CAD by approximately 15%.« less

Kambo cleanse is a purification, cleansing ritual traditionally performed by South American shaman to confer luck and health to hunters. We report a patient who presented to the emergency department with prolonged symptoms of vomiting, flushing, facial swelling, altered mental status, and agitation requiring chemical restraints, 22 h after a Kambo cleanse. The patient was found with four small, circular, superficial burns to the ankle at the site where the resin was introduced. The cleanse consists of rubbing resin obtained from the secretions of the giant leaf frog (Phyllomedusa bicolor) into superficial wounds to produce intense gastrointestinal symptoms followed by a sensation of increased stamina and strength. The cleanse is now being increasingly performed in Europe and USA.

To date, there are no legally binding requirements concerning product testing in cosmetics. This leads to various manufacturer-specific test methods and absent transparent information on skin cleansing products. A standardized in vivo test procedure for assessment of cleansing efficacy and corresponding barrier impairment by the cleaning process is needed, especially in the occupational context where repeated hand washing procedures may be performed at short intervals. For the standardization of the cleansing procedure, an Automated Cleansing Device (ACiD) was designed and evaluated. Different smooth washing surfaces of the equipment for ACiD (incl. goat hair, felt, felt covered with nitrile caps) were evaluated regarding their skin compatibility. ACiD allows an automated, fully standardized skin washing procedure. Felt covered with nitrile as washing surface of the rotating washing units leads to a homogenous cleansing result and does not cause detectable skin irritation, neither clinically nor as assessed by skin bioengineering methods (transepidermal water loss, chromametry). Automated Cleansing Device may be useful for standardized evaluation of the cleansing effectiveness and parallel assessment of the corresponding irritancy potential of industrial skin cleansers. This will allow objectifying efficacy and safety of industrial skin cleansers, thus enabling market transparency and facilitating rational choice of products. © 2013 John Wiley & Sons A/S.

1984-01-01

The requirements of a significant quantity of proposed life sciences experiments in Shuttle payloads for available wash water to support cleansing operations has provided the incentive to develop a technique for wash water renovation. A prototype wash water waste renovation system which has the capability to process the waste water and return it to a state adequate for reuse in a typical cleansing fixture designed to support life science experiments was investigated. The resulting technology is to support other developments efforts pertaining to water reclamation by serving as a pretreatment step for subsequent reclamation procedures.

Randomized trials from South Asia indicate umbilical cord chlorhexidine cleansing reduces mortality and omphalitis. No community-based data are available on bacteriological profile of the cord, early neonatal colonization dynamics, or impact of cord cleansing on colonizing organisms. Such data could clarify the design of scaled chlorhexidine interventions. Umbilical swabs were collected at home (days 1, 3, 6) after birth from infants participating in a trial of 3 cord-care regimens (no chlorhexidine, single cleansing, multiple cleansing) in Sylhet, Bangladesh. Overall and organism-specific positivity rates were estimated by cord-care regimen and by day of collection. Between September 2008 and October 2009, 1923 infants contributed 5234 umbilical swabs. Positivity rate was high (4057 of 5234, 77.5%) and varied substantially across groups. Immediate (day 1) reductions in cord colonization were observed in single- (prevalence rate ratio = 0.75, 95% confidence interval: 0.70-0.81) and multiple- (prevalence rate ratio = 0.71, 95% confidence interval: 0.66-0.77) cleansing groups. Reductions persisted and increased in magnitude through day 6 only if babies received multiple applications. On days 1, 3, and 6, respectively, multiple cleansing consistently reduced invasive organisms such as Escherichia coli (49%, 64%, and 42% lower), Klebsiella pneumoniae (46%, 53%, and 33% lower), and Staphylococcus aureus (34%, 84%, and 85% lower). Cord cleansing with 4.0% chlorhexidine immediately after birth reduces overall and organism-specific colonization of the stump. Reductions are greater and sustained longer with daily cleansing through the first week of life, suggesting that programs promoting chlorhexidine cleansing should favor multiple over single applications.

To assess the efficacy of low-volume powder polyethylene glycol (PEG)-3350 as a sole bowel preparation for colonoscopy. This case series examined 245 consecutive patients (a mixture of inpatients and outpatients undergoing screening colonoscopy) at a hospital endoscopy center over a 2-year period. The patients received powder PEG-3350 in the amount of 204 g dissolved in 32 oz of water and taken in 3 divided doses 1 hour apart with 8 oz of water in between each dose. Colon preparation scores (CPS) were used to assess the quality of colon cleansing. The results obtained from the 245 patients were collated and compared to those of patients receiving sodium phosphate, the historical control. The mean CPS was calculated to be 3.43, with a standard deviation of 1.12. Of the 245 patients, 92 were scored with a grade of 4, and 5 patients had incomplete colonoscopies secondary to failure of bowel preparation (CPS=0). Among the remaining patients, 22 and 26 were graded as poor (CPS=1) or fair (CPS=2) bowel preparations, respectively. The low-volume powder PEG-3350 formula used in our case series showed effective colon cleansing and may be considered for use as a sole bowel preparation.

Individuals engage in moral cleansing, a compensatory process to reaffirm one’s moral identity, when one’s moral self-concept is threatened. However, too much moral cleansing can license individuals to engage in future unethical acts. This study examined the effects of incentives and consequences of one’s actions on cheating behavior and moral cleansing. Results found that incentives and consequences interacted such that unethical thoughts were especially threatening, resulting in more moral cleansing, when large incentives to cheat were present and cheating explicitly harmed others. Implications are discussed in terms of ethics training, using incentives as motivators, and the depersonalized norms of science. PMID:26085781

Previous reports showed that cosmetic cleansing oil for removing makeup, which contains mineral oil and surfactant, can deform some silicone hydrogel contact lenses (SHCLs) when applied directly to the lenses, although plasma-coated SHCLs (lotrafilcon A and B) were not affected. In the present study, we investigated hydrogel lenses and SHCLs in both wet and dry conditions. Several brands of hydrogel and SHCLs were immersed in a cleansing oil solution containing Sudan Black B for 5 min under wet and dry conditions. The lenses under the wet condition were simply picked up from the saline, whereas those under the dry condition were blotted with paper wipes. After immersing, the excess solution remaining on the lenses was removed by finger rubbing with a multipurpose solution. The lenses were then examined using a stereomicroscope, and their mean brightness was measured and compared. The cosmetic cleansing oil was not absorbed by the hydrogel lenses under wet or dry conditions. However, four of seven brands of SHCLs absorbed the cosmetic cleansing oil under both conditions (dry and wet), whereas asmofilcon A absorbed it only under the dry condition. Lotrafilcon B and delefilcon A did not absorb cleansing oil even under the dry condition. Hydrogel lenses resist cosmetic cleansing oil. However, SHCLs have different degrees of resistance depending on the lens material. Some SHCLs absorbed cosmetic cleansing oil more under dry conditions than under wet conditions.

To evaluate interrelationships between bacterial vaginosis (BV), vaginal yeast, vaginal practices (cleansing and drying/tightening), mucosal inflammation, and HIV acquisition. A multicenter, prospective, observational cohort study was conducted, enrolling 4531 HIV-negative women aged 18 to 35 years attending family planning clinics in Zimbabwe and Uganda. Participants were tested for HIV and reproductive tract infections and were interviewed about vaginal practices every 3 months for 15 to 24 months. BV was measured by Gram stain Nugent scoring, vaginal yeast by wet mount, and mucosal inflammation by white blood cells on Gram stain. HIV incidence was 4.12 and 1.53 per 100 woman-years of follow-up in Zimbabwe and Uganda, respectively (a total of 213 incident infections). Women with BV or vaginal yeast were more likely to acquire HIV, especially if the condition was present at the same visit as the new HIV infection and the visit preceding it (hazard ratio [HR] = 2.50, 95% confidence interval [CI]: 1.68 to 3.72 and HR = 2.97, 95% CI: 1.67 to 5.28 for BV and yeast, respectively). These relationships did not seem to be mediated by mucosal inflammation. Vaginal drying/tightening was associated with HIV acquisition in univariate (HR = 1.49, 95% CI: 1.03 to 2.15) but not multivariate models. Vaginal cleansing was not associated with HIV acquisition. BV and yeast may contribute more to the HIV epidemic than previously thought.

Effect of bowel cleansing on colonic transit in constipation due to slow transit or evacuation disorder.

Sloots, C E J; Felt-Bersma, R J F

2002-02-01

Colon transit time measurement with radio-opaque markers is a method of studying the passage of luminal contents throughout the colon. Overall colonic transit time (CTT), as well as segmental transit times [right (RTT), left (LTT) and rectosigmoid (RSTT)], can be calculated. We hypothesize that CTT is influenced by faecal impaction when the rectum is emptied infrequently. The aim of this study is to investigate the effect of bowel cleansing on colonic transit time in patients with chronic constipation. In 25 women (age 41 years; range 20-65 years) with constipation according to Thompson criteria, CTT measurement was performed in an unprepared situation and repeated after cleansing with 4 L of Klean-Prepreg. Ten healthy female volunteers (age 41 years; range 27-57 years) were used as controls. In constipated patients, CTT decreased from a median 70 h (range 10-130 h) to 48 h (5-94 h) in the cleansed state (P < 0.001). A shortening of transit time was found in all three segments. In 10 patients with slow transit (ST) (CTT > 86 h), CTT decreased from 110 h (range 94-130) to 86 (38-94) (P < 0.001). Five of the 10 patients with ST before bowel cleansing had a CTT below 86 h after cleansing. In female controls, uncleansed CTT and RSTT shortened from 39 h (23 to 62) and 17 h (8-29) to 29 h (17-48) and 10 h (0-20) after bowel cleansing (P=0.058 and P=0.046). Colonic intraluminal contents have a substantial effect on colonic transit. In female controls, bowel cleansing shortened rectosigmoid transit. Women with constipation had faster transit in the cleansed state, however, the distribution of markers was not altered. Despite the effect of bowel cleansing on CTT, it seems unnecessary to prepare the bowel in clinical practice because the differentiation of patients between slow transit constipation and outlet obstruction is not changed. However, because in an infrequent defecation pattern, the influence of faecal impaction is considerable, CTT should be applied with care for critical clinical decisions in the treatment of constipation.

The 2 L polyethylene glycol (PEG) lavage solution has been proved to be similarly safe and effective as 4 L PEG formulations, in spite of the reduced volume. To compare low-volume PEG-based solution combined with ascorbic acid with high-volume PEG-based solution combined with simethicon in terms of efficacy and patient tolerability. This was a single-blind prospective randomized trial. Patients were randomized to receive either 2 L PEG plus ascorbic acid (PEG+Asc) or 4 L PEG plus simethicon (PEG+Sim). The primary endpoint was overall colon cleansing evaluation, assessed by blinded investigators using Aronchick score. Secondary end points included patient compliance and tolerability and adverse events. Sixty patients received PEG+Asc and 60 received PEG+Sim. Overall bowel cleansing score was considered adequate in 81.67% of the PEG+Asc and 80% of the PEG+Sim groups, respectively. Excellent and good ratings were recorded in 11.6% and 38.3% receiving PEG+Asc as compared with 26.6% and 23.3% of patients receiving PEG+Sim. Patient tolerability and safety were similar with both the preparations. According to our data, low-volume PEG+Asc has comparable efficacy, safety, and tolerability as high-volume PEG+Sim; therefore, it can be considered as a good alternative solution for bowel preparation. More improvements are necessary to achieve the target of a perfect preparation.

To analyze the changes occurred in the nasal cavity geometry, before and after nasal cleansing, through nasal aeration and acoustic rhinometry in children with oral breathing. Twenty children aged four to 12 years were included in the study. The gathering of participants was conducted at the Multifunctional Laboratory of the Speech Pathology Department of the Federal University of Pernambuco - UFPE. The following procedures were conducted: Identification Index of Signs and Symptoms of Oral Breathing; marking of nasal expiratory airflow using the graded mirror of Altmann, and examination of the Nasal Geometry by Acoustic Rhinometry. The same procedures were performed after nasal massage and cleansing with saline solution. Significant change was observed in the areas with respect to the nasal airflow on both sides after nasal cleansing and massage. As for nasal geometry, measured by acoustic rhinometry, comparison between the nostrils showed that the effect of cleansing and massage was discrete. Nasal aeration measures showed sensitivity to the cleansing and massage technique and measures of nasal geometry confirmed its effect on respiratory physiology.

To determine whether three epidural catheter port cleansing techniques used to apply a povidone-iodine solution differed with respect to the introduction of this solution through the epidural catheter. Experimental. Laboratory. Five DuPen (Davol, Cranston, RI) epidural catheters. Five DuPen epidural catheters each were cleansed twice with (a) a commercially available 10% povidone-iodine swabstick, (b) a commercially available pledget impregnated with 10% povidone-iodine, and (c) a gauze pad saturated with 10% povidone-iodine. The order of cleansing was randomized. Each solution was used to clean the port for 30 seconds, and the port was allowed to dry for 30 seconds, similar to the technique used in the clinical setting. After cleaning the catheter port, water was injected through the catheter, and the solution from the tip of the catheter was analyzed using absorbance spectrophotometry. Cleansing techniques, presence of povidone-iodine in catheter. A statistically significant difference existed between the three cleansing techniques, with the pledget yielding the lowest values of povidone-iodine contamination of the epidural catheter (Freidman test, p = 0.02). Use of pledgets allowed the least amount of povidone-iodine to enter the epidural catheter as compared with the swabsticks or gauze pads. Commercially available pledgets used to cleanse catheter injection ports may limit the introduction of 10% povidone-iodine into the epidural or intrathecal space.

Evaluation of mild skin cleansers.

PubMed

Wortzman, M S

1991-01-01

Each person makes the decision of how best to care for his or her own skin. Among the prime concerns, especially for facial skin, is the type of dirt, debris, or make-up to be removed. In most cases, all products do an adequate job in the removal of dirt; if not, the washing techniques can be modified to accomplish the task at hand. What cannot be controlled are the adverse side effects inherent in the use of that product. These adverse properties include damages to the barrier function of the skin; increased susceptibility to environmental sources of irritation and sensitization; frank irritation responses, such as erythema and edema; and reduction of the cosmetic qualities of the skin, such as degree of moisture and smoothness. Part of the problem is that most of these changes are subtle, occurring slowly over time. Often, the association of these problems with the use of a particular facial cleansing regimen is overlooked. The typical woman uses as many as 10 to 15 facial cosmetic and cleansing products each day, making the identification of a problem even more difficult. It is important to identify the risks associated with individual products and with product categories in general. Although the identification of a safe group of products to use for facial cleansing is desirable, the results of this investigation indicate that there are no simple answers. It has been assumed that because moisturizing cream formulations are routinely safe and mild in general use, a cleansing product in the same general form would share these attributes. We can see from the results in Table 2 and Figures 2, 3, 5, 7, and 9 that cleansing creams are not uniformly superior to cleansing bars in the key attributes that are used to evaluate mildness. In each evaluation there were individual cleansing creams that demonstrated statistically weaker performance than did cleansing bars in general. As a group, cleansing creams did well in the cosmetic categories of dryness and texture but surprisingly poorly in such indicators of clinical safety as erythema and TEWL. Further evaluation of the components of the facial-washing regimens proposed by the manufacturers of many of the cleansing-cream products involved the direct comparison of a cleansing cream against that same product used with an alcohol-based toning product. In all cases, the addition of alcohol-based products to the cleaning protocol reduced the cosmetic and clinical safety of the regimen (see Table 2 and Figures 3, 5, 7, and 9).(ABSTRACT TRUNCATED AT 400 WORDS)

With its long-lasting effectiveness, octenidine is an agent of first choice for antiseptic wound treatment. However, the manufacturer advises against instillation of the agent under pressure. A 50-year-old patient presented with erythema and extensive soft tissue induration after wound cleansing with octenidine under pressure. Due to the lack of resorption of the agent, this caused long-lasting interstitial soft tissue edema. This case demonstrates the importance of following the manufacturer's instructions for use. Advantages of the agent such as lack of systemic toxicity or broad spectrum efficacy can only be achieved if the agent is applied correctly.

Colonoscopy plays an important role in the diagnosis and treatment of gastrointestinal illness in both Western countries and Japan. However, preparative bowel cleansing for colonoscopy is frequently troublesome for elderly and/or constipated patients, since they must drink larger volumes of lavage solution for adequate cleansing. We investigated the use of prokinetic agents for improving the efficacy and tolerability of bowel cleansing prior to colonoscopy. 613 patients were divided into two groups according to oral lavage solution used (polyethylene glycol or magnesium citrate), and were further randomized to receive either vehicle (100 ml water) alone, vehicle with 5 mg mosapride citrate, or vehicle with 50 mg itopride hydrochloride 30 min before administration of lavage solution. Experimental parameters included bowel cleansing quality, times to first defecation and completion of bowel cleansing, and incidence of uncomfortable abdominal symptoms during colonoscopy preparation. Administration of mosapride citrate or itopride hydrochloride prior to oral lavage solution did not significantly improve bowel cleansing quality. However, statistically significantly fewer uncomfortable abdominal symptoms were found in patients who received mosapride citrate or itopride hydrochloride versus vehicle alone. Prokinetic agents effectively decreased the incidence of uncomfortable abdominal symptoms experienced during colonoscopy preparation. Copyright 2008 S. Karger AG, Basel.

Impact of the Quality of Bowel Cleansing on the Efficacy of Colonic Cancer Screening: A Prospective, Randomized, Blinded Study

PubMed Central

2015-01-01

Objectives Efficacy of two low volume bowel cleansing preparations, polyethylene glycol plus ascorbate (PEG+Asc) and sodium picosulfate/magnesium citrate (NaPic/MgCit), were compared for polyp and adenoma detection rate (PDR and ADR) and overall cleansing ability. Primary endpoint was PDR (the number of patients with ≥1 polypoid or flat lesion recorded by the colonoscopist). Methods Diagnostic, surveillance or screening colonoscopy patients were enrolled into this investigator-blinded, multi-center Phase IV study and randomized 1:1 to receive PEG+Asc (administered the evening before and the morning of colonoscopy, per label) or NaPic/MgCit (administered in the morning and afternoon the day before colonoscopy, per label). The blinded colonoscopist documented any lesion and assessed cleansing quality (Harefield Cleansing Scale). Results Of 394 patients who completed the study, 393 (PEG+Asc, N=200; NaPic/MgCit, N=193) had a colonoscopy. Overall PDR for PEG+Asc versus NaPic/MgCit was 51.5% versus 44.0%, p=0.139. PDR and ADR on the right side of the bowel were significantly higher with PEG+Asc versus NaPic/MgCit (PDR: 56[28.0%] versus 32[16.6%], p=0.007; ADR: 42[21.0%] versus 23[11.9%], p=0.015), as was detection of flat lesions (43[21.5%] versus 25[13.0%], p=0.025). Cleansing quality was better with PEG+Asc than NaPic/MgCit (98.5% versus 57.5% considered successful cleansing). Overall, there were 132 treatment-emergent adverse events (93 versus 39 for PEG+Asc and NaPic/MgCit, respectively). These were mainly mild abdominal symptoms, all of which were reported for higher proportions of patients in the PEG+Asc than NaPic/MgCit group. Twice as many patients in the NaPic/MgCit versus the PEG+Asc group reported tolerance of cleansing solution as ‘very good’. Conclusions Compared with NaPic/MgCit, PEG+Asc may be more efficacious for overall cleansing ability, and subsequent detection of right-sided and flat lesions. This is likely attributable to the different administration schedules of the two bowel cleansing preparations, which may positively impact the detection and prevention of colorectal cancer, thereby improving mortality rates.

Patient compliance with bowel cleansing procedures represents one of the most objectionable aspects of colonoscopy. Adverse reactions to the purgative may result in failure to complete the preparation, inadequate visualization of the colon, polyp and even carcinoma miss rate and unwillingness to attend a follow-up colonoscopy. The primary objective of the study was to evaluate the effectiveness of bowel cleansing with magnesium sulphate and low-volume polyethylene glycol (PEG) with electrolytes. The second objective was to evaluate whether bowel cleansing was better in participants scheduled for morning colonoscopies or afternoon colonoscopies. Magnesium sulphate mineral water (2 l) and 2 l of low-volume PEG and electrolytes solution were used as our bowel cleansing protocol. A total of 13 914 participants, who participated in the Slovenian colorectal cancer screening programme in the period between 2009 and 2011, were included. Excellent bowel preparation was achieved in 11 484 (82.61%) participants; 1894 (13.62%) participants had good bowel preparation, 439 (3.16%) participants had fair bowel preparation and 85 (0.61%) participants had poor bowel preparation. Better results were achieved in the afternoon colonoscopies and in younger participant groups (P<0.001). No serious side effects of bowel cleansing were reported. This is the first study to use magnesium sulphate mineral water and PEG plus electrolytes for bowel cleansing. We found excellent bowel cleansing in 82.61% participants and in more participants if colonoscopy was performed in the afternoon.

Reports an error in "Embodiment as procedures: Physical cleansing changes goal priming effects" by Ping Dong and Spike W. S. Lee ( Journal of Experimental Psychology: General , 2017[Apr], Vol 146[4], 592-605). In the article, the following F-value and p-values in the Results section of Experiment 3 were set incorrectly: The p -value p =.925 should be p =.922. The F - and p -values F (1, 201)=.011, p =.916 should be F (1, 201) .014, p = .906. (The following abstract of the original article appeared in record 2017-14922-010.) Physical cleansing reduces the influence of numerous psychological experiences, such as guilt from immoral behavior, dissonance from free choice, and good/bad luck from winning/losing. How do these domain-general effects occur? We propose an integrative account of cleansing as an embodied procedure of psychological separation. By separating physical traces from a physical target object (e.g., detaching dirt from hands), cleansing serves as the embodied grounding for the separation of psychological traces from a psychological target object (e.g., dissociating prior experience from the present self). This account predicts that cleansing reduces the accessibility of psychological traces and their consequences for judgments and behaviors. Testing these in the context of goal priming, we find that wiping one's hands (vs. not) decreases the mental accessibility (Experiment 1), behavioral expression (Experiment 2), and judged importance (Experiments 3-4) of previously primed goals (e.g., achievement, saving, fitness). But if a goal is primed after cleansing, its importance gets amplified instead (Experiment 3). Based on the logic of moderation-of-process, an alternative manipulation that psychologically separates a primed goal from the present self produces the same effects, but critically, the effects vanish once people wipe their hands clean (Experiment 4), consistent with the notion that cleansing functions as an embodied procedure of psychological separation. These findings have implications for the flexibility of goal pursuit. More broadly, our procedural perspective generates novel predictions about the scope and mechanisms of cleansing effects and may help integrate embodied and related phenomena.

Low-volume bowel preparations with polyethylene glycol (PEG) have been shown to provide an equivalent cleansing with improved tolerability as compared with standard PEG bowel preparation for colonoscopy. A new iso-osmotic sulphate-free formulation of PEG-Citrate-Simethicone (PEG-CS) in combination with bisacodyl has been recently developed. To compare the quality of bowel cleansing with PEG-CS with bisacodyl vs. PEG-Ascorbate (PEG-ASC) in adult out-patients undergoing colonoscopy. Randomised, observer-blind, parallel group study in adult out-patients undergoing colonoscopy in five Italian centres. Both preparations were taken the evening before the procedure. Subjects were instructed to take 2-4 tablets of 5 mg bisacodyl at 16:00 hours and 2 L of PEG-CS at 20:00 hours or 2 L of PEG-ASC plus 1 L of additional water the day before colonoscopy. Bowel cleansing was evaluated according to the Boston Bowel Preparation Scale (≥6 scores were considered as 'clinical success'), and mucosal visibility according to a 3-point scale. Tolerability, acceptability and compliance were also evaluated. Four hundred and eight patients were randomly allocated to PEG-CS and bisacodyl (n = 204, male patient 48%, mean age 59.1 years) or PEG-ASC (n = 204, male patient 51%, age 59.4 years). In the planned per-protocol analysis, the rate of successful preparation was 79.1% following PEG-CS with bisacodyl, and 70% following PEG-ASC (P < 0.05). Mucosal visibility was evaluated as optimal in 56.1% in the PEG-CS and bisacodyl and 46.3% in the PEG-ASC group (P < 0.05). There were no serious adverse events (AE) in each of the two experimental groups. Two subjects in the PEG-ASC group discontinued the study because of AE. Polyethylene glycol-Citrate-Simethicone in combination with bisacodyl was more effective for bowel cleansing than PEG-ASC for out-patient colonoscopy. Tolerability, safety, acceptability and compliance of the two low-volume bowel preparations were similar. © 2012 Blackwell Publishing Ltd.

The aim of this study was to evaluate the efficacy of various bowel preparations in accomplishing colonic cleansing for optimal mucosal visualization during colonoscopy. The study included a cohort of 980 patients who underwent colonoscopy at our endoscopy center within the last 3 years. All of the study patients were subdivided into four groups. Each group included 245 patients, all receiving a different type of bowel preparation. The bowel preparations used in this study included: magnesium citrate (Group I), a combination of oral sodium phosphate (fleets) and powder PEG-3350 (Group II), powder polyethylene glycol-3350 (PEG-3350 powder for Group III), and oral sodium phosphate (fleets for Group IV). A Colon Prep Score (CPS) was devised to compare the quality of the different bowel preparations used. The colonoscopy results from all of these patients were tabulated and analyzed statistically and expressed as mean ± 1 standard deviation. Statistical analysis was performed using a one way ANOVA with Holm-Sidak method for intergroup analysis. Group I patients received magnesium citrate and had a mean CPS ± 1 SD of 3.11 ± 0.91. Group II patients (fleets and powder PEG-3350 combination) achieved a CPS of 3.37 ± 1.16. The patients in Group III (powder PEG-3350) actually showed the highest mean CPS of 3.44 ± 1.12. Group IV patients who used oral sodium phosphate alone reached a mean CPS of 3.23 ± 1.01. Group III patients (powder PEG-3350 only) demonstrated a statistically higher CPS (P<0.0006) in colon cleansing as compared to Group I patients (magnesium citrate). Similarly, Group II patients (oral sodium phosphate and powder PEG-3350 combination) also showed improved colon cleansing statistically (P<0.006) as compared to Group I patients (magnesium citrate). Overall, all four colon preparations achieved an average CPS greater than 3.0 indicating clinically adequate colonic cleansing. However, powder PEG-3350 alone and in combination with oral sodium phosphate was observed to be statistically superior to magnesium citrate, when used for colon preparation for colonoscopy.

ATP bioluminescence, based on the firefly luciferase system, is used for the rapid determination of hygienic practices in the food industry. This study has demonstrated the use of caged ATP as an internal ATP standard and quantified the effects of industrial cleansing solutions, alcoholic beverages and pH on firefly luciferase activity. The light signal was quenched 6-47% by five cleansing solutions at standard working concentrations. Ethanol at 1% (v/v) inhibited bioluminescence by 15% (w/v) whereas concentrations above 4% enhanced the light output. The light signal was quenched by 20-25% at pH values below pH 4 and above pH 10.

The Bali STD/AIDS study: association between vaginal hygiene practices and STDs among sex workers.

Reed, B D; Ford, K; Wirawan, D N

2001-02-01

To assess the association between genital cleansing practices and the prevalence of sexually transmitted diseases and of sexual health knowledge among female sex workers in Bali, Indonesia. Low priced commercial sex workers (CSWs) participated in the Bali STD/AIDS Study, a 3 year educational project evaluating the effect of education on the subsequent use of condoms and the prevalence of STDs and AIDS. Structured interviews, genital evaluation, laboratory evaluation for STDs, and treatment were performed. Vaginal cleansing characteristics including frequency, type, and reasons for use, were evaluated. Associations between these characteristics and the presence of bacterial and viral genital infections were assessed. Of 625 female sex workers evaluated between May and July 1998, 99.1% used substances, such as soap and toothpaste, to clean the vagina at least daily, with 69.3% performing this after each intercourse. The women using such cleansers after each client did not differ from those using them once or less daily in education, AIDS and condom use knowledge, time working as a CSW, or number of clients in the previous day. However, they were younger than those using vaginal cleansers daily or less, and reported lower condom usage in the past week. Several genital symptoms, such as discoloured discharge and odour, were reported less by women with the highest frequency of vaginal cleanser use. Prevalence of genital infections in this population of women was substantial, with bacterial infections more prevalent than viral infections. Infections were not associated with the type of cleanser used, using a genital cleanser on the day of examination, or using a cleanser after each client versus daily or less, except for candida colonisation, which was more prevalent in women cleansing after each client (OR=1.87, 95% CI 1.21, 2.90). However, symptomatic candida vulvovaginitis (positive culture plus presence of symptoms) was not associated with the prevalence of genital cleansing. Women using genital cleansing in part for "infection avoidance" (39.7%) were more likely to have heard of STDs and AIDS, but were less knowledgeable about these infections, compared with women not citing this reason for genital cleansing. Commercial sex workers in low priced brothels in Bali have a high rate of genital infections, with lower rates of viral compared with bacterial infections. Genital cleansers, on a daily or after each intercourse schedule, are used routinely. Although genital cleansing after each intercourse was associated with fewer genital symptoms, the prevalence of STDs did not differ significantly based on this frequency, and the women's knowledge of STDs and AIDS was less than that of women cleansing less often. The effect of genital cleansing in general on STD and AIDS prevalence could not be assessed in this population owing to the lack of a non-cleansing cohort. Further study to elucidate the effect of vaginal cleansing practices on STD prevalence and resistance is needed.

To assess the efficacy of vaginal cleansing before cesarean delivery in reducing postoperative endometritis. MEDLINE, Ovid, EMBASE, Scopus, Clinicaltrials.gov, and Cochrane Library were searched from their inception to January 2017. Selection criteria included all randomized controlled trials comparing vaginal cleansing (ie, intervention group) with a control group (ie, either placebo or no intervention) in women undergoing cesarean delivery. Any method of vaginal cleansing with any type of antiseptic solution was included. The primary outcome was the incidence of endometritis. Meta-analysis was performed using the random-effects model of DerSimonian and Laird to produce summary treatment effects in terms of relative risk (RR) with 95% CI. Sixteen trials (4,837 women) on vaginal cleansing immediately before cesarean delivery were identified as relevant and included in the review. In most of the included studies, 10% povidone-iodine was used as an intervention. The most common way to perform the vaginal cleansing was the use of a sponge stick for approximately 30 seconds. Women who received vaginal cleansing before cesarean delivery had a significantly lower incidence of endometritis (4.5% compared with 8.8%; RR 0.52, 95% CI 0.37-0.72; 15 studies, 4,726 participants) and of postoperative fever (9.4% compared with 14.9%; RR 0.65, 95% CI 0.50-0.86; 11 studies, 4,098 participants) compared with the control group. In the planned subgroup analyses, the reduction in the incidence of endometritis with vaginal cleansing was limited to women in labor before cesarean delivery (8.1% compared with 13.8%; RR 0.52, 95% CI 0.28-0.97; four studies, 440 participants) or those with ruptured membranes (4.3% compared with 20.1%; RR 0.23, 95% CI 0.10-0.52; three studies, 272 participants). Vaginal cleansing immediately before cesarean delivery in women in labor and in women with ruptured membranes reduces the risk of postoperative endometritis. Because it is generally inexpensive and a simple intervention, we recommend preoperative vaginal preparation before cesarean delivery in these women with sponge stick preparation of povidone-iodine 10% for at least 30 seconds. More data are needed to assess whether this intervention may be also useful for cesarean deliveries performed in women not in labor and for those without ruptured membranes.

There are no studies that looked into the bubble eliminating efficacy of polyethylene glycol with ascorbic acid (PEGA), which has been one of the shortcomings of polyethylene glycol (PEG). In this study, we compared newly introduced PEGA regimen by adding either simethicone or 1 L of water. A prospective randomized controlled study was carried out at Dongguk Universtiy Gyeongju Hospital from July 2014 to September 2014. A total of 90 patients were randomly assigned to 3 groups; PEGA group (n=30) which served as control, simethicone addition group (n=30) to which simethicone 400 mg was additionally prescribed, and water addition group (n=30) to whom additional 1 L of water was given. Cleansing effectiveness, gas elimination efficacy, side effects, and patient satisfaction were compared between the groups. PEGA group demonstrated the highest cleansing effectiveness, but there was no statistically significant difference among the groups. Simethicone addition group showed significantly lesser amount of bubbles than the other groups (2.57±2.05 vs. 1.10±1.83 vs. 2.60±2.84, p=0.017). The rates of side effects in each group were 20.00% vs. 16.77% vs. 53.33%. Water addition group had significantly more side effects than the PEGA group and the simethicone addition group (p=0.003). The patient satisfaction score of each group was 3.37±0.85 vs. 3.73±0.74 vs. 3.20±0.66 with simethicone addition group showing significantly higher satisfaction than water addition group (p=0.020). PEGA bowel preparation agent showed satisfactory bowel cleansing despite the decrease in dosage, and addition of simethicone resulted in better bubble elimination.

The approach to small bowel preparation before capsule endoscopy (CE) is still suboptimal. One hundred eighty patients were randomly allocated to 3 groups. Patients in Group A took 250 mL 20% mannitol and 1 L 0.9% saline orally at 05:00 hours on the day of the procedure. In Group B the same preparation was taken at 20:00 on the day before, and at 05:00 on the day of CE; in addition, 20 mL oral simethicone was taken 30 minutes before CE. Group C was treated identically to Group B, except that the patients fasted for 3 days and took 3 g senna orally 3 times daily before CE. The length of bowel containing green luminal contents was assessed by ImageJ software and bowel cleanliness was evaluated by computed assessment of the cleansing score. Cleansing of the whole small bowel and the distal small bowel were significantly different between the 3 groups (χ = 22.470, P = .000; χ = 17.029, P = .000, respectively). There were also significant differences between the 3 groups in the length of small bowel and specifically the length of the distal small bowel containing green luminal contents (χ = 12.390, P = .000, χ = 15.141, P = .000, respectively), but not with regard to the proximal small bowel (χ = 0.678, P = .509). Three days fasting and oral senna, combined with 20% mannitol and simethicone, before CE, can reduce the effects of bile on the small bowel and improve small bowel cleansing, especially in the distal small intestine.

Cesarean delivery is one of the most common surgical procedures performed by obstetricians. Infectious morbidity after cesarean delivery can have a tremendous impact on the postpartum woman's return to normal function and her ability to care for her baby. Despite the widespread use of prophylactic antibiotics, postoperative infectious morbidity still complicates cesarean deliveries. To determine if cleansing the vagina with an antiseptic solution before a cesarean delivery decreases the risk of maternal infectious morbidities, including endometritis and wound complications. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (21 July 2014). We included randomized and quasi-randomized trials assessing the impact of vaginal cleansing immediately before cesarean delivery with any type of antiseptic solution versus a placebo solution/standard of care on post-cesarean infectious morbidity. We independently assessed eligibility and quality of the studies. Five trials randomizing 1946 women (1766 analyzed) evaluated the effects of vaginal cleansing (all with povidone-iodine) on post-cesarean infectious morbidity. The risk of bias was generally low, with the quality of most of the studies being high. Vaginal preparation immediately before cesarean delivery significantly reduced the incidence of post-cesarean endometritis from 7.2% in control groups to 3.6% in vaginal cleansing groups (average risk ratio (RR) 0.39, 95% confidence interval (CI) 0.16 to 0.97, five trials, 1766 women). The risk reduction was particularly strong for women with ruptured membranes (1.4% in the vaginal cleansing group versus 15.4% in the control group; RR 0.13, 95% CI 0.02 to 0.66, two trials, 148 women). No other outcomes realized statistically significant differences between the vaginal cleansing and control groups. No adverse effects were reported with the povidone-iodine vaginal cleansing.The quality of the evidence using GRADE was low for post-cesarean endometritis, moderate for postoperative fever, and low for wound infection. Vaginal preparation with povidone-iodine solution immediately before cesarean delivery reduces the risk of postoperative endometritis. This benefit is particularly realized for women undergoing cesarean delivery with ruptured membranes. As a simple, generally inexpensive intervention, providers should consider implementing preoperative vaginal cleansing with povidone-iodine before performing cesarean deliveries.

Informatics in Radiology: Dual-Energy Electronic Cleansing for Fecal-Tagging CT Colonography

Kim, Se Hyung; Lee, June-Goo; Yoshida, Hiroyuki

2013-01-01

Electronic cleansing (EC) is an emerging technique for the removal of tagged fecal materials at fecal-tagging computed tomographic (CT) colonography. However, existing EC methods may generate various types of artifacts that severely impair the quality of the cleansed CT colonographic images. Dual-energy fecal-tagging CT colonography is regarded as a next-generation imaging modality. EC that makes use of dual-energy fecal-tagging CT colonographic images promises to be effective in reducing cleansing artifacts by means of applying the material decomposition capability of dual-energy CT. The dual-energy index (DEI), which is calculated from the relative change in the attenuation values of a material at two different photon energies, is a reliable and effective indicator for differentiating tagged fecal materials from various types of tissues on fecal-tagging CT colonographic images. A DEI-based dual-energy EC scheme uses the DEI to help differentiate the colonic lumen—including the luminal air, tagged fecal materials, and air-tagging mixture—from the colonic soft-tissue structures, and then segments the entire colonic lumen for cleansing of the tagged fecal materials. As a result, dual-energy EC can help identify partial-volume effects in the air-tagging mixture and inhomogeneous tagging in residual fecal materials, the major causes of EC artifacts. This technique has the potential to significantly improve the quality of EC and promises to provide images of a cleansed colon that are free of the artifacts commonly observed with conventional single-energy EC methods. © RSNA, 2013 PMID:23479680

The efficacy of 2 oral hygiene products, an experimental toothpaste specific for complete denture cleansing and a regular standard toothpaste, was compared in terms of denture biofilm removal and cure of palatal lesions in patients with atrophic chronic candidiasis. The degree of correlation between presence of biofilm and mucosa erythema was also evaluated. Twenty-four complete denture wearers (45-80 years old) were divided into 2 groups: experimental paste and standard toothpaste (Sorriso-Kolynos, Brazil). Both groups received soft toothbrushes. The internal surfaces of upper dentures were stained using 1% sodium fluorescein and photographed at a 45 masculine angle at 0, 15, 30 and 60 days. The slides were scanned and the areas of interest (denture total area and biofilm area) were measured (Image Tool software). The degree of erythema was evaluated on slides according to the Prosthesis Tissue Index. There was a significant reduction (1%) in the degree of biofilm (ANOVA/Tukey) between the two initial visits (0 and 15 days) and the two final visits (30 and 60 days), and in the average erythema scores (Kruskal-Wallis) between 0 and 60 days, in both groups. The Mann-Whitney test showed a significant difference (1%) between pastes in terms of biofilm degree, but no difference was found for the erythema score. Correlation values between biofilm and erythema degree were 0.3801 (experimental paste) and (0.3678 (standard toothpaste). We may therefore conclude that the experimental product was efficient for the removal of denture plaque biofilm.

Tolerability was measured via a patient questionnaire. The intent-to-treat population consisted of 601 patients who self-administered P/MC (n = 304) or 2L PEG-3350 and bisacodyl tablets (n = 297). P/MC was superior to 2L PEG-3350 and bisacodyl tablets in overall colon cleansing (84.2% vs 74.4%; 1-sided 97.5% confidence interval [CI], 3.4) (Aronchick scores of excellent or good) and in cleansing of the ascending (89.5% vs 78.8%; 1-sided 97.5% CI, 4.9), mid (transverse and descending) (92.4% vs 85.9%; 1-sided 97.5% CI, 1.6), and rectosigmoid (92.4% vs 87.2%; 1-sided 97.5% CI, 0.4) segments of the colon (Ottawa scores of excellent, good, or fair). Commonly reported AEs related to the bowel preparations were nausea, vomiting, headache, and chills. Patient-reported tolerability, including ease of consumption and taste, was significantly higher for P/MC than 2L PEG-3350 and bisacodyl tablets (P < .0001). Because of differences in administration and volume of the bowel preparations, the study was designed to be a single-assessor, blinded study. The bowel-cleansing effects and patient acceptability of split-dose P/MC were superior to day-before dosing with 2L PEG-3350 and bisacodyl tablets.

2012-01-01

Background Polyethylene Glycol-3350 without electrolytes (MiraLAX®; Schering-Plough Healthcare Products Inc.) + a carbohydrate-electrolyte solution (Gatorade; PepsiCo Inc.) + bisacodyl is frequently used for bowel cleansing, although limited data quantifies its efficacy and safety. No prior studies have assessed this in a community setting or with PM-only dosing, which is still used frequently. Aim To compare the frequency of excellent/good/fair/poor bowel cleansing with PM-only dosing of MiraLAX®-Gatorade-bisacodyl vs. 4L GoLytely®. Methods This is a retrospective endoscopic database analysis of ≥ 50 year old average-risk individuals with a normal screening colonoscopy at a community hospital and ambulatory endoscopy center. Data was extracted for the last four months when 4L GoLytely® was the preferred bowel purgative and the first 4 months when 238g MiraLAX® in 64 ounces Gatorade and four 5-mg bisacodyl tablets became the preferred purgative. All patients used PM-only dosing of bowel purgative. Results 778 subjects [GoLytely® (n=395) vs. MiraLAX® + Gatorade + bisacodyl (n=383)] were identified. Patients who took the MiraLAX® bowel preparation were more likely to achieve an excellent/good bowel cleansing compared to patients taking the GoLytely® preparation (93.3% vs. 89.3%, respectively; p = 0.048). However, when only ASA Class I patients are studied, there was no difference in frequency of excellent/good bowel cleansing (91.1% vs 93.6%, respectively; p = 0.498). No serious adverse events were identified. An excellent/good bowel cleansing was strongly associated with a recommendation for repeat colonoscopy in 10 years compared to patients with a fair cleansing [OR = 28.01; 95% CI: 13.96-56.19]. Conclusions The MiraLAX® + Gatorade + bisacodyl combination produces similar rates of excellent/good bowel cleansing as compared to GoLytely® in most average-risk individuals undergoing colonoscopy for CRC screening in a community setting.

This paper presents a study of the self-siphon sediment cleansing set (SSCS), a system designed to remove sediment from the deep combined sewer overflow (CSO) chamber during dry-weather periods. In order to get a better understanding of the sediment removal effectiveness and operational conditions of the SSCS system, we carried out a full-scale field study and comparison analysis on the sediment depth changes in the deep CSO chambers under the conditions with and without the SSCS. The field investigation results demonstrated that the SSCS drains the dry-weather flow that accumulated for 50-57 min from the sewer channel to the intercepting system in about 10 min. It is estimated that the bed shear stress in the CSO chamber and sewer channel is improved almost 25 times on average. The SSCS acts to remove the near bed solids with high pollution load efficiently. Moreover, it cleans up not only the new sediment layer but also part of the previously accumulated sediment.

AIM: To evaluate small bowel cleansing quality, diagnostic yield and transit time, comparing three cleansing protocols prior to capsule endoscopy. METHODS: Sixty patients were prospectively enrolled and randomized to one of the following cleansing protocols: patients in Group A underwent a 24 h liquid diet and overnight fasting; patients in Group B followed protocol A and subsequently were administered 2 L of polyethylene glycol (PEG) the evening before the procedure; patients in Group C followed protocol B and were additionally administered 100 mg of simethicone 30 min prior to capsule ingestion. Small bowel cleansing was independently assessed by two experienced endoscopists and classified as poor, fair, good or excellent according to the proportion of small bowel mucosa under perfect conditions for visualization. When there was no agreement between the two endoscopists, the images were reviewed and discussed until a consensus was reached. The preparation was considered acceptable if > 50% or adequate if > 75% of the mucosa was in perfect cleansing condition. The amount of bubbles was assessed independently and it was considered significant if it prevented a correct interpretation of the images. Positive endoscopic findings, gastric emptying time (GET) and small bowel transit time (SBTT) were recorded for each examination. RESULTS: There was a trend favoring Group B in achieving an acceptable (including fair, good or excellent) level of cleansing (Group A: 65%; Group B: 83.3%; Group C: 68.4%) [P = not significant (NS)] and favoring Group C in attaining an excellent level of cleansing (Group A: 10%; Group B: 16.7%; Group C: 21.1%) (P = NS). The number of patients with an adequate cleansing of the small bowel, corresponding to an excellent or good classification, was 5 (25%) in Group A, 5 (27.8%) in Group B and 4 (21.1%) in Group C (P = 0.892). Conversely, 7 patients (35%) in Group A, 3 patients (16.7%) in Group B and 6 patients (31.6%) in Group C were considered to have poor small bowel cleansing (P = 0.417), with significant fluid or debris such that the examination was unreliable. The proportion of patients with a significant amount of bubbles was 50% in Group A, 27.8% in Group B and 15.8% in Group C (P = 0.065). This was significantly lower in Group C when compared to Group A (P = 0.026). The mean GET was 27.8 min for Group A, 27.2 min for Group B and 40.7 min for Group C (P = 0.381). The mean SBTT was 256.4 min for Group A, 256.1 min for Group B and 258.1 min for Group C (P = 0.998). Regarding to the rate of complete examinations, the capsule reached the cecum in 20 patients (100%) in Group A, 16 patients (88.9%) in Group B and 17 patients (89.5%) in Group C (P = 0.312). A definite diagnosis based on relevant small bowel endoscopic lesions was established in 60% of the patients in Group A (12 patients), 44.4% in Group B (8 patients) and 57.8% in Group C (11 patients) (P = 0.587). CONCLUSION: Preparation with 2 L of PEG before small bowel capsule endoscopy (SBCE) may improve small bowel cleansing and the quality of visualization. Simethicone may further reduce intraluminal bubbles. No significant differences were found regarding GET, SBTT and the proportion of complete exploration or diagnostic yield among the three different cleansing protocols. PMID:23424190

The purpose of this study was to determine whether the occurrence of numerous colonic bubbles during CT colonography (CTC) performed with polyethylene glycol cleansing and oral iohexol fecal/fluid tagging could be prevented by use of simethicone. Adults with suspected colonic neoplasia who had been randomly assigned to control and simethicone intervention groups underwent CTC after cleansing with 4 L of polyethylene glycol, tagging with 50 mL of 350 mg I/mL oral iohexol, and without (control) or with (intervention) oral administration of 200 mg of simethicone. Colonic segments in the control and intervention groups were evaluated for amount of colonic bubbles during CTC. A 6-point grading system was used in which 0 indicated no bubbles and 5 indicated that more than three fourths of the air-distended mucosa was covered with bubbles. The primary endpoint was a per-patient colonic bubble grade, derived as an average of the segmental grades. Eighty adults with suspected colonic neoplasia were randomly assigned to the control (40 patients) and simethicone intervention (40 patients) groups. A total of 659 colonic segments in the control group and 689 segments in the intervention group were evaluated for amount of colonic bubbles during CTC. The per-patient colonic bubble score was significantly lower in the simethicone intervention group than in the control group. The mean score was 0.0±0.1 (SD) versus 1.2±0.8 (p<0.001; 95% CI for the mean difference, -1.4 to -1.0). In the intervention group, 673 (97.7%) segments were grade 0, and 16 (2.3%) were grade 1. In contrast, in the control group, 226 (34.3%) segments were grade 0; 173 (26.3%), grade 1; 175 (26.6%), grade 2; 45 (6.8%), grade 3; 23 (3.5%), grade 4; and 17 (2.6%), grade 5. The colonic bubbles associated with fecal/fluid tagging with iohexol can be successfully prevented by adding simethicone to the colonic preparation.

There are no current recommendations for bowel cleansing before colonoscopy in children. The Israeli Society of Pediatric Gastroenterology and Nutrition (ISPGAN) established an iterative working group to formulate evidence-based guidelines for bowel cleansing in children prior to colonoscopy. Data were collected by systematic review of the literature and via a national-based survey of all endoscopy units in Israel. Based on the strength of evidence, the Committee reached consensus on six recommended protocols in children. Guidelines were finalized after an open audit of ISPGAN members. Data on 900 colonoscopies per year were accrued, which represents all annual pediatric colonoscopies performed in Israel. Based on the literature review, the national survey, and the open audit, several age-stratified pediatric cleansing protocols were proposed: two PEG-ELS protocols (polyethylene-glycol with electrolyte solution); Picolax-based protocol (sodium picosulphate with magnesium citrate); sodium phosphate protocol (only in children over the age of 12 years who are at low risk for renal damage); stimulant laxative-based protocol (e. g. bisacodyl); and a PEG 3350-based protocol. A population-based analysis estimated that the acute toxicity rate of oral sodium phosphate is at most 3/7320 colonoscopies (0.041 %). Recommendations on diet and enema use are provided in relation to each proposed protocol. There is no ideal bowel cleansing regimen and, thus, various protocols are in use. We propose several evidence-based protocols to optimize bowel cleansing in children prior to colonoscopy and minimize adverse events. © Georg Thieme Verlag KG Stuttgart · New York.

To prospectively compare the homogeneity, adequacy, and patient acceptance of nonionic iodine-based regimens with those of a barium-based regimen for computed tomographic (CT) colonography with electronic subtraction cleansing. After institutional review board approval and informed consent were obtained, 68 subjects (41 men (60%) men, 27 (40%) women; mean age, 60 years +/- 6 [standard deviation]) with average or moderate risk factors for development of colorectal carcinoma were recruited and placed into three study groups. Group 1 (n = 25) ingested 150-mL aliquots of 2% barium sulfate suspension with meals and snacks for 48 hours prior to imaging, without other diet modification or a cathartic. Group 2 (n = 21) ingested 10-mL aliquots of nonionic iodinated contrast material (iopromide) with a concentration of 300 mg per milliliter with meals and snacks for 2 days before imaging, without diet modification or a cathartic. Group 3 (n = 22) ingested nonionic iodinated contrast material (iohexol) with a concentration of 300 mg per milliliter with meals and snacks for 2 days before imaging and ingested 34 g of magnesium citrate the evening prior to imaging. CT colonography was also performed on 10 control subjects who ingested polyethylene glycol electrolyte solution prior to imaging. Subjective and numerical measures of bowel preparation quality, homogeneity, and patient comfort among the noncathartic and cathartic cohorts were compared with nonparametric analysis of variance, the Fisher exact test, and the F test, as appropriate. The study was HIPAA compliant. Study subjects who received tagging preparations reported significantly improved discomfort scores when compared with those of the control subjects (P < .05, each comparison). There was no significant difference in discomfort scores among groups 1, 2, and 3. For each reader, scores of subtracted image readability were highest for group 3. Dichotomized rates of preparation "success" were also greatest for group 3. In this series, the patient discomfort scores were significantly improved with tagging preparations for CT colonography. Nonionic iodinated contrast material in conjunction with a hyperosmotic laxative (magnesium citrate) was associated with the best subjective and numerical indices of readability. (c) RSNA, 2006.

Budget-impact model for colonoscopy cost calculation and comparison between 2 litre PEG+ASC and sodium picosulphate with magnesium citrate or sodium phosphate oral bowel cleansing agents.

With the availability of several bowel cleansing agents, physicians and hospitals performing colonoscopies will often base their choice of cleansing agent purely on acquisition cost. Therefore, an easy to use budget impact model has been developed and established as a tool to compare total colon preparation costs between different established bowel cleansing agents. The model was programmed in Excel and designed as a questionnaire evaluating information on treatment costs for a range of established bowel cleansing products. The sum of costs is based on National Health Service reference costs for bowel cleansing products. Estimations are made for savings achievable when using a 2-litre polyethylene glycol with ascorbate components solution (PEG+ASC) in place of other bowel cleansing solutions. Test data were entered into the model to confirm validity and sensitivity. The model was then applied to a set of audit cost data from a major hospital colonoscopy unit in the UK. Descriptive analysis of the test data showed that the main cost drivers in the colonoscopy process are the procedure costs and costs for bed days rather than drug acquisition costs, irrespective of the cleansing agent. Audit data from a colonoscopy unit in the UK confirmed the finding with a saving of £107,000 per year in favour of PEG+ASC when compared to sodium picosulphate with magnesium citrate solution (NaPic+MgCit). For every patient group the model calculated overall cost savings. This was irrespective of the higher drug expenditure associated with the use of PEG+ASC for bowel preparation. Savings were mainly realized through reduced costs for repeat colonoscopy procedures and associated costs, such as inpatient length of stay. The budget impact model demonstrated that the primary cost driver was the procedure cost for colonoscopy. Savings can be realized through the use of PEG+ASC despite higher drug acquisition costs relative to the comparator products. From a global hospital funding perspective, the acquisition costs of bowel preparations should not be used as the primary reason to select the preferred treatment agent, but should be part of the consideration, with an emphasis on the clinical outcome.

Urine culture is the gold standard test for revealing the microbial agent causing urinary tract infection (UTI). Culture results are affected by sampling techniques; improper sampling leads to contamination of urine and thus contamination of the culture with urogenital flora. We aimed to evaluate the effect of urogenital cleansing, performed with chlorhexidine-containing genital region cleansing wipes (GRCW) on contamination rates. A total of 2,665 patients with UTI-related complaints and with urine culture requests from various outpatient clinics were enrolled in the study. Of the patients, 1,609 in the experimental group used GRCW before sampling, while 1,046 in the control group did not use any wipes. The contamination rate in the experimental group patients was 7.7%, while it was 15.8% in the control group. Contamination rates were significantly higher in the control group than in the experimental group for both women and men. Contamination rates for children and adults were also significantly lower in the experimental group than in the control group. Our study, conducted in a large population, showed that the use of chlorhexidine-containing cleansing wipes significantly reduced urine culture contamination rates in both genders, in both child and adult age groups. Using GRCW, collection of urine after urogenital area cleansing will decrease the contamination problem.

Purpose: To prospectively compare adequacy of colonic cleansing, adequacy of solid stool and fluid tagging, and patient acceptance by using reduced-volume, 2-L polyethylene glycol (PEG) versus magnesium citrate bowel preparations for CT colonography. Materials and Methods: This study was approved by the institutional Committee on Human Research and was compliant with HIPAA; all patients provided written consent. In this randomized, investigator-blinded study, 50 patients underwent oral preparation with either a 2-L PEG or a magnesium citrate solution, tagging with oral contrast agents, and subsequent CT colonography and segmentally unblinded colonoscopy. The residual stool (score 0 [best] to 3 [worst]) and fluid (score 0 [best] to 4 [worst]) burden and tagging adequacy were qualitatively assessed. Residual fluid attenuation was recorded as a quantitative measure of tagging adequacy. Patients completed a tolerance questionnaire within 2 weeks of scanning. Preparations were compared for residual stool and fluid by using generalized estimating equations; the Mann-Whitney test was used to compare the qualitative tagging score, mean residual fluid attenuation, and adverse effects assessed on the patient experience questionnaire. Results: The mean residual stool (0.90 of three) and fluid burden (1.05 of four) scores for PEG were similar to those for magnesium citrate (0.96 [P = .58] and 0.98 [P = .48], respectively). However, the mean fecal and fluid tagging scores were significantly better for PEG (0.48 and 0.28, respectively) than for magnesium citrate (1.52 [P < .01] and 1.28 [P < .01], respectively). Mean residual fluid attenuation was higher for PEG (765 HU) than for magnesium citrate (443 HU, P = .01), and mean interpretation time was shorter for PEG (14.8 minutes) than for magnesium citrate (18.0 minutes, P = .04). Tolerance ratings were not significantly different between preparations. Conclusion: Reduced-volume PEG and magnesium citrate bowel preparations demonstrated adequate cleansing effectiveness for CT colonography, with better tagging and shorter interpretation time observed in the PEG group. Adequate polyp detection was maintained but requires further validation because of the small number of clinically important polyps. © RSNA, 2011 Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11110217/-/DC1 PMID:21873253

SUMMARY Background. Urinary tract infection (UTI) in the United States is the most common bacterial infection, and urine cultures often make up the largest portion of workload for a hospital-based microbiology laboratory. Appropriately managing the factors affecting the preanalytic phase of urine culture contributes significantly to the generation of meaningful culture results that ultimately affect patient diagnosis and management. Urine culture contamination can be reduced with proper techniques for urine collection, preservation, storage, and transport, the major factors affecting the preanalytic phase of urine culture. Objectives. The purposes of this review were to identify and evaluate preanalytic practices associated with urine specimens and to assess their impact on the accuracy of urine culture microbiology. Specific practices included collection methods for men, women, and children; preservation of urine samples in boric acid solutions; and the effect of refrigeration on stored urine. Practice efficacy and effectiveness were measured by two parameters: reduction of urine culture contamination and increased accuracy of patient diagnosis. The CDC Laboratory Medicine Best Practices (LMBP) initiative's systematic review method for assessment of quality improvement (QI) practices was employed. Results were then translated into evidence-based practice guidelines. Search strategy. A search of three electronic bibliographic databases (PubMed, SCOPUS, and CINAHL), as well as hand searching of bibliographies from relevant information sources, for English-language articles published between 1965 and 2014 was conducted. Selection criteria. The search contained the following medical subject headings and key text words: urinary tract infections, UTI, urine/analysis, urine/microbiology, urinalysis, specimen handling, preservation, biological, preservation, boric acid, boric acid/borate, refrigeration, storage, time factors, transportation, transport time, time delay, time factor, timing, urine specimen collection, catheters, indwelling, urinary reservoirs, continent, urinary catheterization, intermittent urethral catheterization, clean voided, midstream, Foley, suprapubic, bacteriological techniques, and microbiological techniques. Main results. Both boric acid and refrigeration adequately preserved urine specimens prior to their processing for up to 24 h. Urine held at room temperature for more than 4 h showed overgrowth of both clinically significant and contaminating microorganisms. The overall strength of this body of evidence, however, was rated as low. For urine specimens collected from women, there was no difference in rates of contamination for midstream urine specimens collected with or without cleansing. The overall strength of this evidence was rated as high. The levels of diagnostic accuracy of midstream urine collection with or without cleansing were similar, although the overall strength of this evidence was rated as low. For urine specimens collected from men, there was a reduction in contamination in favor of midstream clean-catch over first-void specimen collection. The strength of this evidence was rated as high. Only one study compared midstream collection with cleansing to midstream collection without cleansing. Results showed no difference in contamination between the two methods of collection. However, imprecision was due largely to the small event size. The diagnostic accuracy of midstream urine collection from men compared to straight catheterization or suprapubic aspiration was high. However, the overall strength of this body of evidence was rated as low. For urine specimens collected from children and infants, the evidence comparing contamination rates for midstream urine collection with cleansing, midstream collection without cleansing, sterile urine bag collection, and diaper collection pointed to larger reductions in the odds of contamination in favor of midstream collection with cleansing over the other methods of collection. This body of evidence was rated as high. The accuracy of diagnosis of urinary tract infection from midstream clean-catch urine specimens, sterile urine bag specimens, or diaper specimens compared to straight catheterization or suprapubic aspiration was varied. Authors' conclusions. No recommendation for or against is made for delayed processing of urine stored at room temperature, refrigerated, or preserved in boric acid. This does not preclude the use of refrigeration or chemical preservatives in clinical practice. It does indicate, however, that more systematic studies evaluating the utility of these measures are needed. If noninvasive collection is being considered for women, midstream collection with cleansing is recommended, but no recommendation for or against is made for midstream collection without cleansing. If noninvasive collection is being considered for men, midstream collection with cleansing is recommended and collection of first-void urine is not recommended. No recommendation for or against is made for collection of midstream urine without cleansing. If noninvasive collection is being considered for children, midstream collection with cleansing is recommended and collection in sterile urine bags, from diapers, or midstream without cleansing is not recommended. Whether midstream collection with cleansing can be routinely used in place of catheterization or suprapubic aspiration is unclear. The data suggest that midstream collection with cleansing is accurate for the diagnosis of urinary tract infections in infants and children and has higher average accuracy than sterile urine bag collection (data for diaper collection were lacking); however, the overall strength of evidence was low, as multivariate modeling could not be performed, and thus no recommendation for or against can be made.

The need for colonoscopy is common among diabetic patients. However, there are no standards per se for bowel preparation in patients with type 2 diabetes. In this study, we evaluated the efficacy, safety, and tolerability of sodium phosphate (NaP), and the quality of bowel cleansing in relation to glycemic control and late complications. A total of 50 consecutive type 2 diabetic patients and 50 non-diabetic patients underwent bowel preparation by NaP. Fasting blood glucose, sodium (Na), potassium (K), calcium (Ca), phosphorus (P), magnesium, and creatinine levels were measured on the procedure day. Patients were given a tolerability questionnaire regarding symptoms. With regard to bowel preparation quality, optimal bowel cleansing was achieved in 35 (70%) diabetic and 47 (94%) non-diabetic patients (P = 0.002). Abdominal pain or discomfort during and an hour after the procedure was similar in both groups (P >0.05). The changes in Na, K, Ca, P and creatinine levels after NaP use did not reach statistical significance between the groups (P >0.05). In the diabetic patients, there was a significant correlation between the quality of bowel cleansing and mean age, duration of diabetes mellitus, level of hemoglobin A1c (HbA1c), fasting blood glucose level, and diabetic late complications (P <0.05). These data suggest that NaP is safe and tolerable in diabetic patients, but the quality of bowel cleansing is worse than in non-diabetic patients. These observations support the concept that the quality of bowel cleansing in those with type 2 diabetes is closely related to the duration and regulation of the disease and the presence of late complications.

To assess the properties of a novel body wash containing the mild surfactant glycinate. Biochemical and clinical assays. Research laboratories and clinical sites in the United States and Canada. Women 18 to 65 years of age (cleansing efficacy); male and female subjects 26 to 63 years of age with mild or moderate dryness and erythema (leg-controlled application test); subjects 5 to 65 years of age with mild-to-moderate eczema (eczema compatibility); and women 18 to 64 years of age (home use). Assessments across studies included colorimetric dye exclusion to assess skin damage potential (corneosurfametry), efficacy of cosmetic product removal from skin, change from baseline in visual dryness, change from baseline in Eczema Area and Severity Index, and self-perceived eczema attributes and self-reported product preference. The glycinate-based cleanser demonstrated mildness to skin components when evaluated in a corneosurfametry assay. Short-term use under exaggerated wash conditions in subjects with dryness scores <3 and erythema scores <2 (both on a 0-6 scale) indicated an initial reduction in visual dryness. In subjects with eczema, normal use resulted in significant improvements (p<0.05) at Week 4 compared with baseline in skin dryness (change from baseline = -0.73), rash (-0.56), itch (-0.927), tightness (-0.585), and all eczema (-0.756). The glycinate-based body wash removed 56 percent of a long-lasting cosmetic foundation from skin compared with less than 30 percent removed by two competitive products tested. The glycinate-based body wash was preferred over a competitive mild cleansing product overall. The patented glycinate-containing body wash demonstrated better product mildness and patient-preferred attributes and clinical benefits.

AIM: To compare the bowel cleansing efficacy of same day ingestion of 4-L sulfa-free polyethylene glycol (4-L SF-PEG) vs 2-L polyethylene glycol solution with ascorbic acid (2-L PEG + Asc) in patients undergoing afternoon colonoscopy. METHODS: 206 patients (mean age 56.7 years, 61% male) undergoing outpatient screening or surveillance colonoscopies were prospectively randomized to receive either 4-L SF-PEG (n = 104) or 2-L PEG + Asc solution (n = 102). Colonoscopies were performed by two blinded endoscopists. Bowel preparation was graded using the Ottawa scale. Each participant completed a satisfaction and side effect survey. RESULTS: There was no difference in patient demographics amongst groups. 4-L SF-PEG resulted in better Ottawa scores compared to 2-L PEG + Asc, 4.2 vs 4.9 (P = 0.0186); left colon: 1.33 vs 1.57 respectively (P = 0.0224), right colon: 1.38 vs 1.63 respectively (P = 0.0097). No difference in Ottawa scores was found for the mid colon or amount of fluid. Patient satisfaction was similar for both arms but those assigned to 4-L SF-PEG reported less bloating: 23.1% vs 11.5% (P = 0.0235). Overall polyp detection, adenomatous polyp and advanced adenoma detection rates were similar between the two groups. CONCLUSION: Morning only 4-L SF-PEG provided superior cleansing with less bloating as compared to 2-L PEG + Asc bowel preparation for afternoon colonoscopy. Thus, future studies evaluating efficacy of morning only preparation for afternoon colonoscopy should use 4-L SF-PEG as the standard comparator. PMID:25132784

Background and study aims  Dietary restrictions are integral to colonoscopy preparation and impact patient satisfaction. Utilizing split-dose, lower-volume polyethylene glycol 3350-electrolyte solution (PEG-ELS), this study compared colon preparation adequacy of a low-residue diet to clear liquids using a validated grading scale. Patients and methods  This was a prospective, randomized, single-blinded, single-center non-inferiority study evaluating diet the day prior to outpatient colonoscopy. Subjects were randomized to a Low-Residue diet for breakfast and lunch, or Clears only. All subjects received split dose PEG-ELS. The primary endpoint was preparation adequacy using the Boston Bowel Preparation Scale (BBPS), with adequate defined as a score > 5. Secondary endpoints included mean BBPS scores for the entire colon and individual segments, satisfaction, adverse events, polyp and adenoma detection rates, and impact on sleep and daily activities. Results  Final analysis included 140 subjects, 72 assigned to Clears and 68 to Low-Residue. The Low-Residue diet was non-inferior to Clears (risk difference = - 5.08 %, P  = 0.04) after adjusting for age. Mean colon cleansing scores were not significantly different overall and for individual colonic segments. Satisfaction with the Low-Residue diet was significantly greater ( P  = 0.01). The adenoma detection rate was not statistically significantly different between study groups, but the number of adenomas detected was significantly greater with Clears ( P  = 0.01). Adverse events and impact on sleep and activities did not differ significantly between diet arms. Conclusions  A low-residue diet for breakfast and lunch the day prior to colonoscopy was non-inferior to clear liquids alone for achieving adequate colon cleansing when using split dose PEG-ELS.

The Moral Virtue of Authenticity: How Inauthenticity Produces Feelings of Immorality and Impurity.

PubMed

Gino, Francesca; Kouchaki, Maryam; Galinsky, Adam D

2015-07-01

The five experiments reported here demonstrate that authenticity is directly linked to morality. We found that experiencing inauthenticity, compared with authenticity, consistently led participants to feel more immoral and impure. This link from inauthenticity to feeling immoral produced an increased desire among participants to cleanse themselves and to engage in moral compensation by behaving prosocially. We established the role that impurity played in these effects through mediation and moderation. We found that inauthenticity-induced cleansing and compensatory helping were driven by heightened feelings of impurity rather than by the psychological discomfort of dissonance. Similarly, physically cleansing oneself eliminated the relationship between inauthenticity and prosocial compensation. Finally, we obtained additional evidence for discriminant validity: The observed effects on desire for cleansing were not driven by general negative experiences (i.e., failing a test) but were unique to experiences of inauthenticity. Our results establish that authenticity is a moral state--that being true to thine own self is experienced as a form of virtue. © The Author(s) 2015.

Case series: PTSD symptoms in adolescent survivors of "ethnic cleansing." Results from a 1-year follow-up study.

The authors describe the psychiatric sequelae of "ethnic cleansing" in adolescent Bosnian refugees, via a 1-year follow-up study. Ten Bosnian adolescent refugees from the war in Bosnia-Herzegovina received a baseline assessment within the first year after their resettlement and a follow-up assessment 1 year later. Evaluations included an assessment scale for posttraumatic stress disorder (PTSD) symptom severity. At baseline, 3 subjects met criteria for PTSD. At follow-up, this diagnosis persisted in none of these subjects, though 1 subject met criteria at follow-up only. For the group, mean PTSD severity scores at baseline and at follow-up were 8.9 and 4.0, respectively. At baseline, reexperiencing symptoms were present 43% of the time, avoidance symptoms were present 33% of the time, and hyperarousal symptoms were present 33% of the time; at follow-up, these proportions were 35%, 16%, and 18%, respectively. Overall, rates of PTSD symptoms diminished during the 1-year follow-up interval, suggesting that they may be transient and not representative of enduring psychopathology. This finding may reflect the relative resiliency of adolescents, as well as a variety of factors that facilitated adaptation in our particular group of adolescent refugees.

Cleansing the world of the germ of laziness: hygiene, sanitation, and the Javanese population in Suriname.

PubMed

Hoefte, Rosemarijn

2014-01-01

In 1915 the Rockefeller Foundation took its hookworm eradication campaign to Suriname, but was soon disappointed because of opposition from its main target group: the Javanese. Moreover, authorities and planters objected to the construction of latrines because of the costs and their belief that the Javanese were "unhygienic". In describing the labor migration from Java to Suriname, I show that this "lack of hygiene" was closely related to the system's organization. I argue that uncleanliness was the consequence of harmful socio-economic and ecological conditions. Secondly I suggest that even though the Foundation did not manage to cleanse Suriname of hookworm, its educational efforts, its emphasis on prevention, and its training of local health workers probably had more impact than Rockefeller officials thought.

The high volume and poor palatability of 4 L of polyethylene glycol (PEG)-based bowel cleansing preparation required before a colonoscopy represent a major obstacle for patients. The aim of this study was to compare two low volume PEG-based preparations with standard 4 L PEG in individuals with a positive fecal immunochemical test (FIT) within organized screening programs in Italy. A total of 3660 patients with a positive FIT result were randomized to receive, in a split-dose regimen, 4 L PEG or 2 L PEG plus ascorbate (PEG-A) or 2 L PEG with citrate and simethicone plus bisacodyl (PEG-CS). The noninferiority of the low volume preparations vs. 4 L PEG was tested through the difference in proportions of adequate cleansing. A total of 2802 patients were included in the study. Adequate bowel cleansing was achieved in 868 of 926 cases (93.7 %) in the 4 L PEG group, in 872 out of 911 cases in the PEG-A group (95.7 %, difference in proportions  + 1.9 %, 95 % confidence interval [CI]  - 0.1 to 3.9), and in 862 out of 921 cases in the PEG-CS group (93.6 %, difference in proportions  - 0.2 %, 95 %CI  - 2.4 to 2.0). Bowel cleansing was adequate in 95.5 % of cases when the preparation-to-colonoscopy interval was between 120 and 239 minutes, whereas it dropped to 83.3 % with longer intervals. Better cleansing was observed in patients with regular bowel movements (95.6 %) compared with those with diarrhea (92.4 %) or constipation (90.8 %). Low volume PEG-based preparations administered in a split-dose regimen guarantee noninferior bowel cleansing compared with 4 L PEG. Constipated patients require a personalized preparation.

Background Intravaginal practices (IVP) are highly prevalent in sub-Saharan African and have been implicated as risk factors for HIV acquisition. However, types of IVP vary between populations, and detailed information on IVP among women at risk for HIV in different populations is needed. We investigated IVP among women who practice transactional sex in two populations: semi-urban, facility workers in Tanzania who engage in opportunistic sex work; and urban, self-identified sex workers and bar workers in Uganda. The aim of the study was to describe and compare IVP using a daily pictorial diary. Methodology/Principal Findings Two hundred women were recruited from a HIV prevention intervention feasibility study in Kampala, Uganda and in North-West Tanzania. Women were given diaries to record IVP daily for six weeks. Baseline data showed that Ugandan participants had more lifetime partners and transactional sex than Tanzanian participants. Results from the diary showed that 96% of Tanzanian participants and 100% of Ugandan participants reported intravaginal cleansing during the six week study period. The most common types of cleansing were with water only or water and soap. In both countries, intravaginal insertion (e.g. with herbs) was less common than cleansing, but insertion was practiced by more participants in Uganda (46%) than in Tanzania (10%). In Uganda, participants also reported more frequent sex, and more insertion related to sex. In both populations, cleansing was more often reported on days with reported sex and during menstruation, and in Uganda, when participants experienced vaginal discomfort. Participants were more likely to cleanse after sex if they reported no condom use. Conclusions While intravaginal cleansing was commonly practiced in both cohorts, there was higher frequency of cleansing and insertion in Uganda. Differences in IVP were likely to reflect differences in sexual behaviour between populations, and may warrant different approaches to interventions targeting IVP. Vaginal practices among women at high risk in Uganda and Tanzania: recorded behaviour from a daily pictorial diary. PMID:23555618

Texture-based CAD improves diagnosis for low-dose CT colonography

Computed tomography (CT)-based virtual colonoscopy or CT colonography (CTC) currently utilizes oral contrast solutions to tag the colonic fluid and possibly residual stool for differentiation from the colon wall and polyps. The enhanced image density of the tagged colonic materials causes a significant partial volume (PV) effect into the colon wall as well as the lumen space (filled with air or CO II). The PV effect on the colon wall can "bury" polyps of size as large as 5mm by increasing their image densities to a noticeable level, resulting in false negatives. It can also create false positives when PV effect goes into the lumen space. We have been modeling the PV effect for mixture-based image segmentation and developing text-based computer-aided detection of polyp (CADpolyp) by utilizing the PV mixture-based image segmentation. This work presents some preliminary results of developing and applying texture-based CADpolyp technique to low-dose CTC studies. A total of 114 studies of asymptomatic patients older than 50, who underwent CTC and then optical colonoscopy (OC) on the same day, were selected from a database, which was accumulated in the past decade and contains various bowel preparations and CT scanning protocols. The participating radiologists found ten polyps of greater than 5 mm from a total of 16 OC proved polyps, i.e., a detection sensitivity of 63%. They scored 23 false positives from the database, i.e., a 20% false positive rate. Approximately 70% of the datasets were marked as imperfect bowel cleansing and/or presence of image artifacts. The impact of imperfect bowel cleansing and image artifacts on VC performance is significant. The texture-based CADpolyp detected all the polyps with an average of 2.68 false positives per patient. This indicates that texture-based CADpolyp can improve the CTC performance in the cases of imperfect cleansed bowels and presence of image artifacts.

Abstract Background and Study Aims: The approach to small bowel preparation before capsule endoscopy (CE) is still suboptimal. Patients and Methods: One hundred eighty patients were randomly allocated to 3 groups. Patients in Group A took 250 mL 20% mannitol and 1 L 0.9% saline orally at 05:00 hours on the day of the procedure. In Group B the same preparation was taken at 20:00 on the day before, and at 05:00 on the day of CE; in addition, 20 mL oral simethicone was taken 30 minutes before CE. Group C was treated identically to Group B, except that the patients fasted for 3 days and took 3 g senna orally 3 times daily before CE. The length of bowel containing green luminal contents was assessed by ImageJ software and bowel cleanliness was evaluated by computed assessment of the cleansing score. Results: Cleansing of the whole small bowel and the distal small bowel were significantly different between the 3 groups (χ2 = 22.470, P = .000; χ2 = 17.029, P = .000, respectively). There were also significant differences between the 3 groups in the length of small bowel and specifically the length of the distal small bowel containing green luminal contents (χ2 = 12.390, P = .000, χ2 = 15.141, P = .000, respectively), but not with regard to the proximal small bowel (χ2 = 0.678, P = .509). Conclusions: Three days fasting and oral senna, combined with 20% mannitol and simethicone, before CE, can reduce the effects of bile on the small bowel and improve small bowel cleansing, especially in the distal small intestine.

Design, fabrication and acceptance testing of a zero gravity whole body shower, volume 1

NASA Technical Reports Server (NTRS)

1973-01-01

The effort to design whole body shower for the space station prototype is reported. Clothes and dish washer/dryer concepts were formulated with consideration given to integrating such a system with the overall shower design. Water recycling methods to effect vehicle weight savings were investigated and it was concluded that reusing wash and/or rinse water resulted in weight savings which were not sufficient to outweigh the added degree of hardware complexity. The formulation of preliminary and final designs for the shower are described. A detailed comparison of the air drag vs. vacuum pickup method was prepared that indicated the air drag concept results in more severe space station weight penalties; therefore, the preliminary system design was based on utilizing the vacuum pickup method. Tests were performed to determine the optimum methods of storing, heating and sterilizing the cleansing agent utilized in the shower; it was concluded that individual packages of pre-sterilized cleansing agent should be used. Integration features with the space station prototype system were defined and incorporated into the shower design as necessary.

Studies of contamination of three broiler breeder houses with Salmonella enteritidis before and after cleansing and disinfection.

Three broiler breeder houses on three different sites were sampled before and after cleansing and disinfection. None of the farms achieved total elimination of Salmonella enteritidis from the poultry house environment but substantial improvements were seen when errors in the cleansing and disinfection protocol in the first house had been corrected. Fundamental errors such as over-dilution and inconsistent application of disinfectants were observed despite supervision of the process by technical advisors. In each of the three poultry units failure to eliminate a mouse population that was infected with S. enteritidis was likely to be the most important hazard for the next flock.

The aim of the study was to assess the cleansing-effect of two endodontic handpieces (Excalibur, W & H; MM 1400 Micro Méga) in root canals that were previously manually prepared, and treated with chlor-(Neomagnol) and citric acid containing solutions. The analyses were performed by scanning electron microscope (SEM). The elimination of the Smear Layer (SL) with Neomagnol was not successful with either of the two handpieces. The cleansing of the Superficial Debris (SD) with Neomagnol activated by MM 1400 was significantly more effective in the apical (p < 0.05) and in the middle (p < 0.01) third of the root-canal, than by Excalibur. In contrast, SL was better eliminated by Excalibur using citric acid, significant differences--when compared with MM 1400--could be seen in the middle third (p < 0.05) of the root-canal. The handpieces seem to have their own specific characteristics: thus MM 1400 was better in eliminating the SD (used with Neomagnol), while Excalibur was superior in eliminating the SL (used with citric acid).

We investigated condom and lubricant use, rectal cleansing and rectal gel use for penile-anal intercourse (PAI), during in-depth interviews with women from South Africa, Uganda and Zimbabwe who formerly participated in VOICE, a five-arm HIV prevention trial of two antiretroviral tablets and a vaginal gel. Few studies have addressed practices related to PAI among women; existing data from Africa on condom and lubricant use for PAI, as well as preparatory practices of PAI such as rectal cleansing, are limited to men who have sex with men. Women demonstrated a lack of awareness of HIV transmission risks of PAI and none of the participants reported using condom-compatible lubricants for PAI. Participants described a variety of preparatory rectal cleansing practices. Some participants disclosed rectal use of the vaginal study gel. Understanding practices related to PAI in Africa is critical to microbicide development, as these practices are likely to influence the acceptability, feasibility, and use of both vaginal and rectal microbicide products.

The goal was to compare the efficacy of oral 25% dextrose treatment and/or skin-to-skin contact for analgesia in term newborns during intramuscular injection of a hepatitis B vaccine. A prospective, randomized, partially blinded, clinical trial was performed with 640 healthy term newborns. Infants at 12 to 72 hours of life were assigned randomly to receive an intramuscular injection of hepatitis B vaccine in the right thigh according to 4 analgesia groups, that is, no analgesia (routine); oral 25% dextrose treatment, given 2 minutes before the injection; skin-to-skin contact, initiated 2 minutes before the injection and persisting throughout the procedure; and a combination of the oral dextrose treatment and skin-to-skin contact strategies. For all groups, Neonatal Facial Coding System and Neonatal Infant Pain Scale scores were evaluated before the procedure, during thigh cleansing, during the injection, and 2 minutes after the injection. Premature Infant Pain Profile scores also were assessed for all infants. Pain scores were compared among the 4 groups. The use of oral 25% dextrose treatment reduced the duration of procedural pain in the studied population. Skin-to-skin contact decreased injection pain and duration. The combination of the 2 analgesic measures was more effective than either measure separately for term newborns. Nonpharmacologic analgesic measures were effective for the treatment of procedural pain in term infants. The combination of oral 25% dextrose treatment and skin-to-skin contact acted synergistically to decrease acute pain in healthy neonates.

Necrotizing fasciitis (NF) is a severe, rare, potentially lethal soft tissue infection that develops in the scrotum and perineum, the abdominal wall, or the extremities. The infection progresses rapidly, and septic shock may ensue; hence, the mortality rate is high (median mortality 32.2%). Prognosis becomes poorer in the presence of co-morbidities, such as diabetes mellitus, immunosuppression, chronic alcohol disease, chronic renal failure, and liver cirrhosis. NF is classified into four types, depending on microbiological findings. Most cases are polymicrobial, classed as type I. The clinical status of the patient varies from erythema, swelling, and tenderness in the early stage to skin ischemia with blisters and bullae in the advanced stage of infection. In its fulminant form, the patient is critically ill with signs and symptoms of severe septic shock and multiple organ dysfunction. The clinical condition is the most important clue for diagnosis. However, in equivocal cases, the diagnosis and severity of the infection can be secured with laboratory-based scoring systems, such as the laboratory risk indicator for necrotizing fasciitis score or Fournier’s gangrene severity index score, especially in regard to Fournier’s gangrene. Computed tomography or ultrasonography can be helpful, but definitive diagnosis is attained by exploratory surgery at the infected sites. Management of the infection begins with broad-spectrum antibiotics, but early and aggressive drainage and meticulous debridement constitute the mainstay of treatment. Postoperative management of the surgical wound is also important for the patient’s survival, along with proper nutrition. The vacuum-assisted closure system has proved to be helpful in wound management, with its combined benefits of continuous cleansing of the wound and the formation of granulation tissue.

After heavy rainfall, sewer overflow spills to receiving water bodies cause serious concern for the environment, aesthetics and public health. To overcome these problems this study investigated a new self-cleansing sewer overflow screening device. The device has a sewer overflow chamber, a rectangular tank and a slotted ogee weir to capture the gross pollutants. To design an efficient screening device a numerical computational fluid dynamic (CFD) model was used. A plausibility check of the CFD model was done using a one-dimensional analytical model. Results showed that an inlet parallel to the weir ensured better self-cleansing than an inlet perpendicular to the weir. Perforations should be at the bottom of the weir to get increased velocity and shear stress to create a favourable self-cleaning effect of the screening device. Increasing inlet length from 0.3 to 1.5 m reduced wave reflection up to 10%, which increased flow uniformity downstream and improved self-cleansing effect. The orientation of the ogee weir with the rectangular tank was found most uniform with a 1:3 (horizontal:vertical) slope. These results will help to maximise functional efficiency of the new sewer overflow screening device. Otherwise it would be too expensive to alter after installation and at times difficult to customise accordingly to existing urban drainage systems.

The aim of this work was an elaboration of mild cleansing compositions, containing supercritical CO2 extract from strawberry seeds (SC-CO2 strawberry seed oil), as a moisturizing and skin-softening agent. The influence of concentration of the oil on user properties of shower/bath products was studied. A series of products (shower/bath cosmetics) composed mainly of mild surfactants (amphoacetates, sulfosuccinates, betaines) and containing different amounts of the oil (0.5 up to 5.0%) were prepared. For the stable products (formulations containing up to 2% of the oil), the influence of the SC-CO2 strawberry seed oil addition on the products' stability, foam ability, surface tension, pH and rheological properties was studied. Moreover, the skin compatibility and moisturizing efficiency of the cleansing products were recorded in a group of 15 volunteers (including 10 women and five men, aged 20-30 years), using skin diagnosis system AramoTS, Aram Huvis Co. Additionally, characterization of CO2 extract from strawberry seeds was performed. Measurements of the oil's analytical constants, that is acid value and saponification number, were conducted according to Polish Standard PN-EN ISO 660:2010 and PN-EN ISO 3657:2013, respectively. The oil concentration influences stability of the products. Only the formulations containing 0.5-2% of the extract have shown high stability. Moreover, used in the amount up to 2% the SC-CO2, strawberry seed oil does not affect significantly the cleansing and foaming properties of the products. The obtained shower/bath cosmetics showed good user properties and additionally good skin-moisturizing effect. The supercritical CO2 extract from strawberry seeds, rich source of unsaturated fatty acid, could be successfully used in the formulation of body washing compositions as a moisturizing and skin-softening agent. © 2015 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Background: Yoga and Ayurveda texts emphasize the role of cleansing the bowel as an important component of management of hypertension (HTN). Observations during our clinical experience and pilot studies on Laghu shankha prakshalana kriya (LSP), a yogic bowel cleansing technique, appeared to be safe and complimentary. Objective: To test the safety and effectiveness of LSP in patients with essential hypertension. Materials and Methods: This self control study recruited 32 patients with mild to moderate essential HTN admitted for a week long residential integrated yoga therapy program at the integrative health home in Bengaluru. Patients had a daily routine of 6 hours of integrated approach of yoga therapy (IAYT) module for HTN that included physical postures, relaxation sessions, pranayama and meditations. LSP, an additional practice, that involved drinking of luke-warm water (with or without a herbal combination, triphala) followed by a set of specific yoga postures that activates defecation reflex, was administered on 2nd (LSP without triphala) and 5th day (LSP with triphala). Assessments (sitting blood pressure and pulse rate) were done just before and after both the sessions of LSP. Secondary outcome measures such as body mass index (BMI), symptom scores, medication scores, fatigue, state and trait anxiety, general health and quality of life were assessed on 1st and 6th day of IAYT intervention. Results: There was significant (P < 0.001, paired t test) reduction in blood pressure (systolic and diastolic) and pulse rate immediately after both the sessions (LSP with and without triphala). There were no adverse effects reported during or after LSP. There was no significant difference between the two techniques (P < 0.505, independent samples t test), although the percentage change appeared to be higher after triphala LSP session. The number of visits to clear the bowel during the procedure was significantly (P < 0.001, independent samples t test) higher after LSP with triphala than LSP without triphalā. After weeklong IAYT, there were significant reductions in blood pressure (P < 0.001), BMI (P < 0.004), medication score (P < 0.001), symptoms score (P < 0.001), fatigue (P < 0.001), state and trait anxiety (STAI, P < 0.001), scores of general ill health (GHQ, P < 0.001), and increase in comfort level (P < 0.001) and quality of sleep (P < 0.001). Conclusion: LSP (a part of IAYT) is a safe and useful procedure for patients with essential hypertension. LSP with triphala is more useful. PMID:25624697

AIM To performed a systematic review and meta-analysis to determine any possible differences in terms of effectiveness, safety and tolerability between existing colon-cleansing products in patients with inflammatory bowel disease. METHODS Systematic searches were performed (January 1980-September 2016) using MEDLINE, EMBASE, Scopus, CENTRAL and ISI Web of knowledge for randomized trials assessing preparations with or without adjuvants, given in split and non-split dosing, and in high (> 3 L) or low-volume (2 L or less) regimens. Bowel cleansing quality was the primary outcome. Secondary outcomes included patient willingness-to-repeat the procedure and side effects/complications. RESULTS Out of 439 citations, 4 trials fulfilled our inclusion criteria (n = 449 patients). One trial assessed the impact of adding simethicone to polyethylene glycol (PEG) 4 L with no effect on bowel cleansing quality, but a better tolerance. Another trial compared senna to castor oil, again without any differences in term of bowel cleansing. Two trials compared the efficacy of PEG high-volume vs PEG low-volume associated to an adjuvant in split-dose regimens: PEG low-dose efficacy was not different to PEG high-dose; OR = 0.84 (0.37-1.92). A higher proportion of patients were willing to repeat low-volume preparations vs high-volume; OR = 5.11 (1.31-20.0). CONCLUSION In inflammatory bowel disease population, PEG low-volume regimen seems not inferior to PEG high-volume to clean the colon, and yields improved willingness-to-repeat. Further additional research is urgently required to compare contemporary products in this population. PMID:28932092

 Colon preparation rates are the limiting factor for a successful diagnostic colonoscopy in children. Different colon cleansing protocols have been published for use in children. Unfortunately, the applicability of those published research protocols has not been formally evaluated in routine clinical practice. We investigated the success rate of our previously published colon cleansing protocol as utilized in our clinical practice.  This was a retrospective study. In the clinical practice, the colon cleansing protocol included PEG-3350 at a dose of 2 g/kg/day plus Dulcolax (Bisacodyl, Boehringer Ingelheim, TX USA) 5 mg/day for 2 days. Adequate colon preparation was graded between 1 - 5, as previously described, and grade ≥ 4.0 was considered an adequate preparation. Patients were instructed to complete a questionnaire that included PEG-3350 dose, number of stools per day, consistency of each stool, and side effects (vomiting, abdominal pain). Clinical and endoscopic results were compared between the protocol under research conditions and routine practice.  The success rate of the colon preparation in our clinical practice was similar to the results observed under our research protocol (75 % vs. 73.6 %). Moreover, the total number of stools, stool consistency, and the intubation rate of the terminal ileum were also similar. We concluded, that in our experience, the colon cleansing protocol used under research conditions was effective and appropriate for use in routine clinical practice.  We recommend testing each new protocol under the routine conditions of clinical practice to confirm its applicability for general practitioners.

The inhibitory effect of indirect latex contamination on the polymerization of vinyl polysiloxane (VPS) impression material has been previously reported. However, the transfer of specific elements that cause inhibition has not been confirmed, nor has the removal of such contaminants been reported. This study examined the surfaces of materials commonly used in restorative procedures that were contaminated by indirect latex glove contact and then evaluated for inhibition of polymerization of VPS. The effect of selected cleansing procedures was then studied. Four experimental groups (n = 8) were prepared: (1) clean vinyl gloves (control), (2) clean gingival retraction cords (control), (3) contaminated vinyl gloves, and (4) contaminated gingival retraction cord. Microscopic evaluation of the appearance and the characterization of surface particulate contamination were performed for each. Three cleansing protocols were then evaluated for efficacy in cleaning vinyl glove surfaces contaminated by latex contact (n = 10): (1) brushing with water, (2) brushing with soap/rinsing with water, (3) cleansing with rubbing alcohol. The subsequent degree of VPS polymerization inhibition was evaluated subjectively. A chi-square test was used for data analysis (alpha=.05). Particulate sulfur elements and sulfur-chloride compounds were present on the contaminated substrates. None of the 3 cleansing procedures eliminated polymerization inhibition (P =.33). Residual elemental sulfur remained on all tested surfaces. Particulate sulfur and sulfur-chloride compounds were identified as the particulate contamination that resulted in polymerization inhibition of the tested VPS dental impression material. Removal of these contaminants from the tested vinyl gloves and gingival retraction cord was not possible with the 3 cleansing protocols tested in this study.

Why Does the “Sinner” Act Prosocially? The Mediating Role of Guilt and the Moderating Role of Moral Identity in Motivating Moral Cleansing

PubMed Central

Numerous studies have found that people tend to commit prosocial acts subsequent to previous immoral acts, as a response to the latter. This phenomenon is called moral cleansing or moral compensation. However, the specific mechanism how previous immoral acts motivate moral compensatory behaviors is still not fully understood. This study aimed to examine the roles of guilt and moral identity in the relation between previous immoral acts and subsequent prosocial behaviors to clarify the mechanism. Based on the extant research, the current study proposed a moderated mediation model to illustrate the process of moral cleansing. Specifically, a previous immoral act motivates guilt, which further leads to subsequent prosocial behaviors, while moral identity facilitates this process. The participants were primed by a recalling task (immoral act vs. a neutral event). The results support the hypothesized model and provide a framework that explains moral cleansing by integrating the roles of guilt and moral identity. These findings highlight the dynamic nature of people’s morality with regard to how people adapt moral behaviors to protect their moral self-image. PMID:27660617

Behavior of pathogenic bacteria in the oyster, Crassostrea commercialis, during depuration, re-laying, and storage.

Oysters (Crassostrea commercials) harvested from major cultivation areas within the state of New South Wales, Australia, were commonly contaminated with low levels of the food-poisoning organisms Bacillus cereus, Clostridium perfringens, and Vibrio parahaemolyticus. Salmonella was found in oysters on only one occasion. These bacteria were cleansed from oysters during oyster purification by re-laying in a non-polluted waterway. Oysters were laboratory contaminated to levels in excess 1,000 cells per g with either B. cereus, C. perfringens, V. parahaemolyticus, Salmonella typhimurium, or S. senftenberg. These species were cleansed from such oysters during purification in a laboratory depuration unit that used ultraviolet light for sterilizing the depuration water. Escherichia coli was also cleansed from oysters under the same re-laying or depuration conditions so that its measurement alone could be used to indicate the cleansing of the above pathogenic species. The levels of these bacteria were also measured during the storage of oysters under conditions that occur during marketing. While B. cereus counts remained relatively stable during storage, the Salmonella spp. gradually decreased in numbers and C. perfringens rapidly died off. V. parahaemolyticus counts increased slightly during the first 4 days of storage, after which decreases occurred. PMID:6257164

2014-01-01

Colonoscopy is a widely accepted method for the evaluation of the colon and terminal ileum. Its diagnostic accuracy and therapeutic safety are influenced by prerequisites, including modulation of medication and bowel cleansing. Appropriate choices of sedative medication and bowel-cleansing regimen, together with diet modification, should be made based on the patient's underlying disease, age, and medication intake. Moreover, effective methods for patient education regarding bowel preparation should be considered. PMID:25133119

In addition to an initial socket discomfort, ocular prosthesis (OP) installation may allow the adherence of fungi and/or bacteria due to the superficial characteristics of the prosthesis’ material, use of inadequate cleansing solutions and methods, or because the void located between the internal portion of the prosthesis and the anophthalmic cavity (AC) mucosa. Objective: The aim of this study was to evaluate OP biofilm formation and the level of contamination of the internal portion of the OP and the AC in 24 patients. Material and Methods: Material was collected from the AC at the beginning of the study and 15 days after cleansing of the OP with 3 cleansing solutions: a neutral liquid soap, a multiuse solution for contact lens (Complete) and 0.12% chlorhexidine (Periogard). The collected materials were sowed in Petri dishes containing selective media for aerobic and facultative microorganisms, specifically staphylococci (Hipersalt agar with egg yolk), aerobic microorganisms (Brain Heart Infusion Blood Agar), streptococci (Mitis salivarius Agar), gram-negative bacilli (MacConkey Agar) and yeasts (Chromagar CandidaTM), incubated at 35°C or 37°C and the number of colony forming units were counted. Data were analyzed statistically by ANOVA, Friedman’s test and Spearman’s correlation. Results: Aerobic microorganisms, gram-negative bacilli and S. aureus were found in the OP biofilm and in the AC. There was statistically significant difference (p<0.05) between the number of microorganisms before and after the use of the cleansing solutions. Conclusion: There was positive correlation with respect to the microorganisms present in the OP biofilm and AC for the 4 proposed treatments, indicating that the decrease of OP contamination leads to AC contamination as well.

Dual-energy electronic cleansing (DE-EC) provides a promising means for cleansing the tagged fecal materials in fecaltagging CT colonography (CTC). However, the increased radiation dose due to the double exposures in dual-energy CTC (DE-CTC) scanning is a major limitation for the use of DE-EC in clinical practice. The purpose of this study was to develop and evaluate a low-dose DE-EC scheme in fecal-tagging DE-CTC. In this study, a custom-made anthropomorphic colon phantom, which was filled with simulated tagged materials by non-ionic iodinated contrast agent (Omnipaque iohexol, GE Healthcare), was scanned by a dual-source CT scanner (SOMATON Definition Flash, Siemens Healthcare) at two photon energies: 80 kVp and 140 kVp with nine different tube current settings ranging from 12 to 74 mAs for 140 kVp, and then reconstructed by soft-tissue reconstruction kernel (B30f). The DE-CTC images were subjected to a low-dose DE-EC scheme. First, our image-space DE-CTC denoising filter was applied for reduction of image noise. Then, the noise-reduced images were processed by a virtual lumen tagging method for reduction of partial volume effect and tagging inhomogeneity. The results were compared with the registered CTC images of native phantom without fillings. Preliminary results showed that our low-dose DE-EC scheme achieved the cleansing ratios, defined by the proportion of the cleansed voxels in the tagging mask, between 93.18% (12 mAs) and 96.62% (74 mAs). Also, the soft-tissue preservation ratios, defined by the proportion of the persevered voxels in the soft-tissue mask, were maintained in the range between 94.67% and 96.41%.

Adjuncts to colonic cleansing before colonoscopy.

PubMed

Park, Sanghoon; Lim, Yun Jeong

Pre-procedural cleansing of the bowel can maximize the effectiveness and efficiency of colonoscopy. Yet, efficacy of the current gold standard colonic preparation method - high-volume oral administration of purgative agents 12-24 h prior to the procedure - is limited by several factors, such as patient compliance (due to poor palatability and inconvenience of the dosing regimen) and risks of complications (due to drug interactions or intolerance). Attempts to resolve these limitations have included providing adjunctive agents and methods to promote the colonic cleansing ability of the principal purgative agent, with the aim of lessening unpleasant side effects (such as bloating) and reducing the large ingested volume requirement. Several promising adjunctive agents are bisacodyl, magnesium citrate, senna, simethicone, metoclopramide, and prokinetics, and each are being investigated for their potential. This review provides an up to date summary of the reported investigations into the potencies and weaknesses of the key adjuncts currently being applied in clinic as supplements to the traditional bowel preparation agents. While the comparative analysis of these adjuncts showed that no single agent or method has yet achieved the goal of completely overcoming the limitations of the current gold standard preparation method, they at least provide endoscopists with an array of alternatives to help improve the suboptimal efficacy of the main cleansing solutions when used alone. To aid in this clinical endeavor, a subjective grade was assigned to each adjunct to indicate its practical value. In addition, the systematic review of the currently available agents and methods provides insight into the features of each that may be overcome or exploited to create novel drugs and strategies that may become adopted as effective bowel cleansing adjuncts or alternatives.

Small-bowel contents can hamper the quality of video-capsule endoscopy (VCE). No standardized protocol has been proposed and overnight fasting remains the proposed preparation for VCE. The aim was to evaluate the effects of 2 regimens of bowel preparation on small intestine cleansing, diagnostic yield and capsule transit times. This is a prospective, randomized, blinded, and controlled study. Sixty patients referred for VCE were randomized into 2 groups. Group A ingested 2l of a polyethylene glycol and simethicone solution 16h before VCE. Group B were instructed to consume a fibre-free diet and allowed to consume clear liquids the day before VCE. The small-bowel cleansing was graded as "complete" if the entire wall was assessable, "incomplete" if more than 50% of the wall was visible, and "insufficient" if less than 50% of the wall was visible. In group A, a "complete", "incomplete" and "insufficient" small-bowel cleansing was achieved in 42%, 39% and 19% of cases respectively. In group B, a "complete", "incomplete" and "insufficient" small-bowel cleansing was achieved in 43%, 33% and 24% of cases respectively. No significant differences were observed between the two groups, regarding small-bowel cleansing level (p=0.65). No differences were also observed in the diagnostic yield (48.2%, 13.8% and 38% vs 65.5%, 6.9% and 27.6% of positive, suspicious and no findings respectively, in groups A and B [p=0.39]) and small-bowel transit times (mean 288min and 299 min in groups A and B respectively [p=0.70]). The results of the present study do not support the use of 2l of a polyethylene glycol and simethicone solution before VCE. Copyright 2009 Editrice Gastroenterologica Italiana S.r.l.

The plastic microbeads, used in many cleansers, will be banned in cosmetic and personal care products within 2017 since they are non-degradable and can disturb the living organisms in water reservoirs. Various choices of biodegradable beads are commercially available, but their efficacy has not been proven yet. This study aimed to compare the cleansing efficacy in dirt and sebum removal aspects of three types of exfoliating beads. The gel scrubs with polyethylene (PE) beads, mannan beads or wax beads, were formulated and evaluated for their stability. The in vivo evaluation was done in 38 healthy volunteers and the skin irritation, efficacy for dirt and sebum removal were measured by Mexameter ® , Colorimeter ® , and Sebumeter ® , respectively. The selected gel scrubs did not cause an irritation in any volunteers. The differences in dirt residues between before and after scrubbing were not statistically significant among three gel scrubs and the similar result was also reported in the sebum removal study. All gel scrubs demonstrated the comparable cleansing efficacy in term of dirt and sebum removal. Thus, mannan beads and wax beads may be replaced non-biodegradable PE beads to achieve the similar cleansing effect. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Application of a high-velocity steam-air micromist jet spray (HVS-AMJS; micromist average diameter: 2.4 μm) for cleansing the skin is proposed. Low-pressure steam is mixed with compressed air (pH 6.5) in a nozzle, and then sprayed at a pressure of ≦0.25 MPa and a velocity of ≧0.34 m/s on the skin or surface of material located approximately 5-10 cm from the nozzle. The temperature on the sprayed surface and water flow rate could be controlled between 42 °C and 46 °C and at approximately 50 mL/min, respectively. Compared with ultrasonic cleansing with tap water and rubbing with only tap water, the HVS-AMJS successfully removed fluorescent lotion covering pieces of wood and significantly reduced both the number of coliforms and the total viable counts on pieces of wood and gauze. Furthermore, the HVS-AMJS effectively removed oily ink from the skin of hairless rats, and temporarily elevated the skin temperature and blood flow, indicating massage effects. The striking characteristics of this cleansing technique using HVS-AMJS are not only its ability to remove microbes and residue without using any chemicals or detergents but also its massage effects.

Spray head translates and rotates to clean entire inner surface of tank or pipe. Cleansing effected by three laterally balanced gas/liquid jets from spray head that rotates about longitudinal axis. Uses much less liquid. Cleaning process in system relies on mechanical action of jets instead of contaminant dissolution. Eliminates very difficult machining needed to make multiple converging/diverging nozzles within one spray head. Makes nozzle much smaller. Basic two-phase-flow, supersonic-nozzle design applied to other spray systems for interior or exterior cleaning.

One hundred Sprague-Dawley rats were subjected to a contamination protocol followed by a cleansing procedure. Four petroleum contaminants and five cleansing solutions were selected. The protocol consisted of shaving, initial punch biopsy, contamination, precleansing punch biopsy, standardized scrub protocol, and postcleansing punch biopsy. Biopsy samples were analyzed for petroleum residue using fluorometry. The 10% DS solution had the highest reduction of crude oil, grease, and tar: 99.6 +/- 0.4% (mean +/- SD) contaminant reduction for crude oil, 99.8 +/- 0.2% for grease, and 99.8 +/- 0.2% for tar. The other cleansers showed less efficacy (p < 0.05). Concentrated DS appears to be significantly more effective at cleaning petroleum products from skin than the commonly chosen surgical and commercial cleansers.

Oral cleansing with chlorhexidine decreases the incidence of nosocomial pneumonia in patients after cardiac surgery. However, evidence of its benefit in ICU patients is conflicting. Patients admitted to the ICU of an Indian tertiary care teaching hospital were randomized to twice-daily oropharyngeal cleansing with 0.2% chlorhexidine or 0.01% potassium permanganate (control) solution. Effects on the incidence of nosocomial pneumonia during ICU stay (primary outcome) and length of ICU stay and in-hospital mortality (secondary outcomes) were studied. Five hundred twelve patients were randomized to either the chlorhexidine group (n = 250) or the control group (n = 262). Of the 471 subjects who completed the protocol, nosocomial pneumonia developed in 16 of 224 subjects (7.1%) in the chlorhexidine group and 19 of 247 subjects (7.7%) in the control group (p = 0.82; relative risk, 0.93; 95% confidence interval, 0.49 to 1.76); intention-to-treat analysis of 21 patients in whom the cleansing protocol was not followed revealed similar results. There was no significant difference between the study and control groups in the median day of development of pneumonia (5.0 days: interquartile range [IQR], 3.0 to 7.7 vs 5.0 days: IQR, 3.0 to 6.0, respectively), median ICU stay (5.0 days: IQR, 3.0 to 8.0 vs 6.0 days: IQR, 3.0 to 8.0, respectively), and mortality (34.8% vs 28.3%, respectively). On subgroup analysis, there was no significant difference in the primary and secondary outcomes in patients on mechanical ventilation, tracheal intubation, and coma (Glasgow coma scale

A scanning electron microscope was used to evaluate the cleansing properties of a 25% tannic acid solution on the dentinal surface in the pulp chamber of endodontically prepared teeth. This was compared with the amorphous smear layer of the canal with the use of hydrogen peroxide and sodium hypochlorite solution as an irrigant. The tannic acid solution removed the smear layer more effectively than the regular cleansing agent.

Electronic cleansing for CT colonography using spectral-driven iterative reconstruction

Dual-energy computed tomography is used increasingly in CT colonography (CTC). The combination of computer-aided detection (CADe) and dual-energy CTC (DE-CTC) has high clinical value, because it can detect clinically significant colonic lesions automatically at higher accuracy than does conventional single-energy CTC. While CADe has demonstrated its ability to detect small polyps, its performance is highly dependent on several factors, including the quality of CTC images and electronic cleansing (EC) of the images. The presence of artifacts such as beam hardening and image noise in ultra-low-dose CTC can produce incorrectly cleansed colon images that severely degrade the detection performance of CTC for small polyps. Also, CADe methods are very dependent on the quality of input images and the information about different tissues in the colon. In this work, we developed a novel method to calculate EC images using spectral information from DE-CTC data. First, the ultra-low dose dual-energy projection data obtained from a CT scanner are decomposed into two materials, soft tissue and the orally administered fecal-tagging contrast agent, to detect the location and intensity of the contrast agent. Next, the images are iteratively reconstructed while gradually removing the presence of tagged materials from the images. Our preliminary qualitative results show that the method can cleanse the contrast agent and tagged materials correctly from DE-CTC images without affecting the appearance of surrounding tissue.

In the medical anthropology section of the Nanterre Hospital (France) for migrants and refugees, three cases were recorded of "virgin cleansing" in sub-Saharan African countries. These consisted of sexual assaults (2 instances of rape and 1 of sexual interference) on sexually immature females (young girls) by patients with sexually transmitted infections (mainly HIV, syphilis) hoping they might thereby be cured. These particularly atrocious hetero-aggressive sexual practices based on magical arguments are unfortunately universal and are not limited to a specific culture. At the medical anthropology level, the belief in cleansing by virgins is based on the notion that the patient is dirty and impure. In the same way that emetics and/or laxatives are prescribed in the case of intestinal disorders (to "eliminate" the disease), some subjects use diuretics for urinary abnormalities or, literally, "clean vaginas (or anuses)" to purge their own miasma. The rising tide of population migrations (some of whom carry chronic infections), refugee camps, prolonged incarcerations, etc., makes observations of such phenomena increasingly frequent. Belief in cleansing by virgins (and the fatal consequences thereof) will be difficult to eradicate. The education of populations and health professionals should promote absolute respect for the body of children, and, more generally, of others, particularly since at this time of increasingly marked migratory flows, this problem sadly risks becoming widespread.

The cleansing efficiencies of laundry detergents depend on composition and variation of ingredients such as surfactants, phosphate, and co-builders. Among these ingredients, surfactants and phosphate are considered as hazardous materials. Knowledge on compositions and micellar behavior is very useful for understanding their cleansing efficiencies and environmental impact. With this view, composition, critical micelle concentration, and dissolved oxygen level in aqueous solution of some laundry detergents available in Bangladesh such as keya, Wheel Power White, Tibet, Surf Excel, and Chaka were determined. Surfactant and phosphate were found to be maximum in Surf Excel and Wheel Power White, respectively, while both of the ingredients were found to be minimum in Tibet. The critical micelle concentration decreased with increasing surfactant content. The amount of laundry detergents required for efficient cleansing was found to be minimum for Surf Excel and maximum for Chaka; however, cleansing cost was the highest for Surf Excel and the lowest for Tibet. The maximum amount of surfactants and phosphate was discharged by Surf Excel and Wheel Power White, respectively, while discharges of both of the ingredients were minimum for Tibet. The maximum decrease of dissolved oxygen level was caused by Surf Excel and the minimum by Tibet. Therefore, it can be concluded that Tibet is cost-effective and environment friendly, whereas Surf Excel and Wheel Power White are expensive and pose a threat to water environment.

There are no widely-accepted methodical specifications with which to objectify cleansing effectiveness and skin compatibility of occuptional skin cleansing products in Europe. Therefore the German Social Insurance Agency (DGUV) initiated a study with the goal to evaluate such products in view of the potency and the safety of hand cleansers. A market analysis was a part of the project. The product descriptions and safety data sheets of 120 products (5-20/manufacturer) of 11 manufacturers were evaluated between 02/2008 and 04/2008. The manufacturers used mainly ingredients of low irritancy. The declaration of the applied ingredients was in the majority of the cases correctly labeled according to the INCI Declaration. Although there was documentation of skin tolerability for most products, the manufacturers used widely differing tests of skin compatibility. Evidences for cleansing effectiveness were not declared or have not been provided. One manufacturer even promised medical effects of its products. There was no uniform general classification of products making it difficult to identify characteristics of cleansers and choose between them. Presently, there are no commonly accepted criteria to classify products in view of cleansing effectiveness und skin compatibility. Generally accepted criteria and test methods are needed for the evaluation of hand cleansers in order to provide the possibility of transparency and comparability. © The Authors • Journal compilation © Blackwell Verlag GmbH, Berlin.

Bowel cleansing before colonoscopy: Balancing efficacy, safety, cost and patient tolerance

PubMed Central

Harrison, Nicole M; Hjelkrem, Michael C

2016-01-01

Effective colorectal cancer screening relies on reliable colonoscopy findings which are themselves dependent on adequate bowel cleansing. Research has consistently demonstrated that inadequate bowel preparation adversely affects the adenoma detection rate and leads gastroenterologists to recommend earlier follow up than is consistent with published guidelines. Poor preparation affects as many as 30% of colonoscopies and contributes to an increased cost of colonoscopies. Patient tolerability is strongly affected by the preparation chosen and manner in which it is administered. Poor tolerability is, in turn, associated with lower quality bowel preparations. Recently, several new developments in both agents being used for bowel preparation and in the timing of administration have brought endoscopists closer to achieving the goal of effective, reliable, safe, and tolerable regimens. Historically, large volume preparations given in a single dose were administered to patients in order to achieve adequate bowel cleansing. These were poorly tolerated, and the unpleasant taste of and significant side effects produced by these large volume regimens contributed significantly to patients’ inability to reliably complete the preparation and to a reluctance to repeat the procedure. Smaller volumes, including preparations that are administered as tablets to be consumed with water, given as split doses have significantly improved both the patient experience and efficacy, and an appreciation of the importance of the preparation to colonoscopy interval have produced additional cleansing.

Introduction The customs of widow cleansing and widow inheritance are practiced in several communities throughout sub-Saharan Africa. In the Nyanza Province of Kenya, according to tradition, Luo widows are expected to engage in sexual intercourse with a “cleanser,” without the use of a condom, in order to remove the impurity ascribed to her after her husband's death. Luo couples, including widows, are also expected to engage in sex preceding specific agricultural activities, building homes, funerals, weddings, and other significant cultural and social events. Widows who are inherited for the purpose of fulfilling cultural obligation have a higher prevalence of HIV than those who remain un-inherited or are inherited for the purpose of companionship. Methods As part of a larger descriptive qualitative study to inform study procedures for FEM-PrEP, an HIV prevention pre-exposure prophylaxis clinical trial, we conducted 15 semi-structured interviews (SSIs) with widows, 15 SSIs with inheritors, and four focus group discussions with widows in the Bondo and Rarieda districts in Nyanza Province to explore the HIV risk context within widow cleansing and inheritance practices. Thematic qualitative analysis was used to analyze the data. Results The majority of widows reported in the demographic questionnaire being inherited, and most widows in the SSIs described participating in the cleansing ritual. We identified two main themes related to HIV prevention within the context of widow cleansing and inheritance: 1) widows must balance limiting their risk for HIV infection with meeting cultural expectations and ensuring that their livelihood needs are met, and 2) sexual abstinence undermines cultural expectations in widowhood while the use of condoms is deemed inappropriate in fulfilling culturally prescribed sexual rituals, and is often beyond the widow's ability to negotiate. Conclusions Women-controlled HIV prevention methods such as antiretroviral-based oral pre-exposure prophylaxis, vaginal gels, and vaginal rings are needed for HIV-negative widows who engage in sexual rituals related to widowhood.

In a previous communication, we demonstrated that, in the prevention of exit-site infection (ESI) in children, the cleansing agent 50% Amuchina (electrolytic chloroxidizer. Amuchina SpA, Genoa, Italy) is more effective than 10% povidone iodine and as effective as 4% chlorhexidine, but with fewer adverse secondary effects. In the present study, we assessed, in an Argentine pediatric population, whether Amuchina 3% is as effective as Amuchina 50% in preventing ESI in children on chronic peritoneal dialysis. In an open-label, single-center prospective study, 27 children (mean age: 7.2 years; range: 1.7-17 years) used 3% Amuchina as a cleansing agent for the daily care of a healthy exit site. Of the 27 children, 14 were switched from 50% Amuchina to 3% Amuchina, and 13 were using the 3% Amuchina for the first time. The control group consisted of 18 patients who had previously used 50% Amuchina as a cleansing agent. We followed the recommendations of the International Society for Peritoneal Dialysis with regard to exit-site care, which include keeping the cleansing agent out of the sinus and rinsing the exit site with sterile water. Amuchina was used from the first post-implantation care of the exit site. No adverse secondary effects were seen with the use of Amuchina at either concentration. Patients using 3% Amuchina presented an ESI rate similar to that of patients using Amuchina 50%. The cost of 3% Amuchina was significantly lower than that of the 50% concentration, and it was even lower than the cost for 10% povidone iodine or 4% chlorhexidine. Although more research trials are needed to assess the efficacy of 3% Amuchina, we conclude that 3% Amuchina is the best and most cost-effective cleansing agent for the daily care of a healthy exit site in children on chronic peritoneal dialysis.

Baby Shampoo Versus Povidone-Iodine or Isopropyl Alcohol in Reducing Eyelid Skin Bacterial Load.

Garcia, Giancarlo A; Nguyen, Christine V; Yonkers, Marc A; Tao, Jeremiah P

Baby shampoo is used as an alternative surgical skin preparation, but the evidence supporting its use is scarce with no descriptions of efficacy in the periocular region. The authors compare the efficacy of baby shampoo, povidone-iodine (PI, Betadine) and isopropyl alcohol (IA) in reducing eyelid skin bacterial load. Prospective, randomized, comparative, and interventional trial. Bacterial load on adult, human eyelid skin was quantitated before and after cleansing with 1) dilute baby shampoo, 2) 10% PI, or 3) 70% IA. Paired skin swabs were collected from a 1 cm area of the upper eyelid of subjects before and after a standardized surgical scrub technique. Samples were cultured on 5% sheep blood agar for 24 hours. The number of colony forming units (CFU) was assessed and bacterial load per square centimeter of eyelid skin was quantified. Baseline and postcleansing samples were assessed from 42 eyelids of 42 subjects (n = 14 for each of baby shampoo, PI, and IA). Before cleansing, similar amounts of bacterial flora were grown from all specimens (median log CFU/cm = 2.04 before baby shampoo, 2.01 before PI, 2.11 before IA; p > 0.05). All 3 cleansing agents significantly reduced the bacterial load (p < 0.01 for each). There was no statistically significant difference in postcleansing bacterial load between the 3 cleansing agents (median log CFU/cm = 0.48 after baby shampoo, 0.39 after PI, 0.59 after IA; p > 0.05). Change from baseline in bacterial load was statistically similar for all 3 agents (median reduction in log CFU/cm = 1.28 with baby shampoo, 1.57 with PI, 1.40 with IA; p > 0.05). These corresponded to bacterial load reductions of 96.3%, 96.6%, and 98.4% for baby shampoo, PI, and IA, respectively. Baby shampoo achieved comparable diminution in eyelid skin bacterial load to PI or IA. These data suggest baby shampoo may be an effective preoperative cleansing agent.

Morality and soap in engineers and social scientists: the Macbeth effect interacts with professions.

PubMed

Schaefer, Michael

2017-11-07

Several studies demonstrate that physical cleansing is actually efficacious to cope with threatened morality, thus demonstrating that physical and moral purity are psychologically interwoven. This so-called Macbeth effect has been explained, for example, by the conceptual metaphor theory that suggests an embodiment of the moral purity metaphor. Recent research draws attention to individual differences when using conceptual metaphors. The present study shows that the moral purity link interacts with different professions. Engineering and social science students were asked to hand copy a text in which the protagonist behaved in an immoral way (or in a moral way, control condition). Subsequently, they had to rate cleansing and other products. Both groups of participants showed higher ratings for cleansing products when hand copying the unethical story, but this Macbeth effect was significantly stronger for the group of engineering students. The results demonstrate that the Macbeth effect interacts with individual differences of the chosen profession. The outcome is discussed in terms of recent theories on individual differences in disgust sensitivity.

Combined low-volume polyethylene glycol solution plus stimulant laxatives versus standard-volume polyethylene glycol solution: A prospective, randomized study of colon cleansing before colonoscopy

Hookey, Lawrence C; Depew, William T; Vanner, Stephen J

2006-01-01

INTRODUCTION The effectiveness of polyethylene glycol solutions (PEG) for colon cleansing is often limited by the inability of patients to drink adequate portions of the 4 L solution. The aim of the present study was to determine whether a reduced volume of PEG combined with stimulant laxatives would be better tolerated and as or more effective than the standard dose. METHODS Patients undergoing outpatient colonoscopy were randomly assigned to receive either low-volume PEG plus sennosides (120 mg oral sennosides syrup followed by 2 L PEG) or the standard volume preparation (4 L PEG). The subjects rated the tolerability of the preparations and their symptoms. Colonoscopists were blind to the colonic cleansing preparation and graded the cleansing efficacy using a validated tool (the Ottawa scale). RESULTS The low-volume PEG plus sennosides preparation was significantly better tolerated than the standard large volume PEG (P<0.001) but was less efficacious (P=0.03). Thirty-eight per cent of patients in the large volume PEG group were unable to finish the preparation, compared with only 6% in the reduced volume group. There were no adverse events reported. CONCLUSIONS Although the low-volume PEG plus sennosides preparation was better tolerated, it was not as effective as standard large-volume PEG. However, in view of the significant difference in tolerance, further research investigating possible improvements in the reduced-volume regimen seems warranted. PMID:16482236

Enzyme-containing personal cleansing products were being considered for the consumer market. Although enzymes have been marketed safely for many years as ingredients in laundry products, their use in a personal cleansing application represented a new type of exposure for consumers that was not supported by the historical safety data. An exposure assessment and additional safety data would be needed before marketing to ensure consumer safety. The work in this paper was designed to evaluate the potential for inhalation exposure to the enzyme during use of this new product while showering. Then a clinical trial was conducted to determine whether or not the level, duration, and routes of exposure encountered during use of this product would induce a Type I sensitization response to the enzyme. Exposure was assessed during normal showering activities by collecting air samples with both high volume and personal samplers and quantitating enzyme levels with an ELISA. To assess the potential for sensitization, panelists were asked to use a prototype protease-containing bar product for all personal cleansing tasks and to keep a use diary reporting any associated symptoms. Physical and dermatologic examinations and skin prick tests with enzyme were conducted before the test commenced and at 2-month intervals. Exposure assessment results showed that airborne enzyme levels were primarily dependent on the concentration of the enzyme in the personal cleansing product. Mean values for total airborne enzyme protein ranged from 5.7 to 11.8 ng/m3 when enzyme concentration, time of use, and measurement technique remained constant. After 6 months of at-home product use, four of 61 test subjects using the enzyme-containing bar had positive skin prick test responses when tested with the enzyme. The skin prick test data were supplemented with serologic analyses, which detected IgE specific for the protease enzyme. None of these subjects showed any clinical symptoms indicative of allergic reaction. The ability of enzymes to induce development of allergic antibodies in this study led to the conclusion that this prototype enzyme-containing personal cleansing bar would represent an inappropriate use of enzymes in a consumer product application. The likelihood of both induction of an immunologic response and subsequent elicitation of allergy symptoms in a small but significant fraction of the user population was high. This finding resulted in the decision to halt further development of this prototype.

Surface alteration of implant screws after function may be associated with mechanicalffailure. This type of metal fatigue appears to be the most common cause of structural failure. The purpose of this study was to evaluate surface alteration of implant screws after function through an examination of used and unused implant screws via scanning electron microscopy (SEM). In this study, abutment screws (Steri-oss, 3i, USA), gold retaining screws (3i, USA), and titanium retaining screws (3i, USA) were retrieved from patients, New, unused abutment, and retaining screws were prepared for a control group. Each of the old, used screws was retrieved with a screwdriver. The retrieved implant complex of a Steri-oss system was also prepared for this study. SEM investigation and energy dispersive spectroscopy (EDS) analysis of the abutment and retaining screws were then performed, as well as SEM investigation of a cross-sectioned sample of the retrieved implant complex in the case of new, unused implant screws, as-manufactured circumferential grooves were regularly examined and screw threads were sharply maintained. Before ultrasonic cleansing of old, used implant screws, there was a large amount of debris accumulation and corrosion products. After ultrasonic cleansing of old, used implant screws, circumferential grooves were examined were found to be randomly deepened and scratching increased. Also, dull screw fhreads were observed. More surface alterations after function were observed in titanium screws than in gold screws. Furthermore, more surface alteration was observed when the screws were retrieved with a driver than without a driver. These surface alterations after function may result in screw instability. Regular cleansing and exchange of screws is therefore recommended. We also recommend the use of gold screws over titanium screws, and careful manipulation of the driver.

Skin contamination by alpha-emitting actinides is a risk to workers during nuclear fuel production and reactor decommissioning. Also, the list of items for potential use in radiological dispersal devices includes plutonium and americium. The actinide chemical form is important and solvents such as tributyl phosphate, used to extract plutonium, can influence plutonium behavior. This study investigated skin fixation and efficacy of decontamination products for these actinide forms using viable pig skin in the Franz cell diffusion system. Commonly used or recommended decontamination products such as water, cleansing gel, diethylenetriamine pentaacetic acid, or octadentate hydroxypyridinone compound 3,4,3-LI(1,2-HOPO), as well as diethylenetriamine pentaacetic acid hydrogel formulations, were tested after a 2-h contact time with the contaminant. Analysis of skin samples demonstrated that more plutonium nitrate is bound to skin as compared to plutonium-tributyl phosphate, and fixation of americium to skin was also significant. The data show that for plutonium-tributyl phosphate all the products are effective ranging from 80 to 90% removal of this contaminant. This may be associated with damage to the skin by this complex and suggests a mechanical/wash-out action rather than chelation. For removal of americium and plutonium, both Trait Rouge cleansing gel and diethylenetriamine pentaacetic acid are better than water, and diethylenetriamine pentaacetic acid hydrogel is better than Osmogel. The different treatments, however, did not significantly affect the activity in deeper skin layers, which suggests a need for further improvement of decontamination procedures. The new diethylenetriamine pentaacetic acid hydrogel preparation was effective in removing americium, plutonium, and plutonium-tributyl phosphate from skin; such a formulation offers advantages and thus merits further assessment.

Neglected aspects in the management of acne.

Acne is the result of excessive grease on the skin. The successful treatment of acne depends essentially on the degreasing of the skin to an extent which produces peeling, which is the observable index of adequate treatment. The use of antibiotics is supplementary to degreasing and peeling. Degreasing is best achieved by thrice daily washing with Neutrogena acne cleansing soap, followed by the application of a benzoyl peroxide preparation of a suitable strength. If necessary, further degreasing can be achieved by cleansing with isopropyl alcohol after washing with the Neutrogena soap. PMID:2941579

The purpose of this paper is to present a CAD prototype system for Crohn's disease. Crohn's disease causes inflammation or ulcers of the gastrointestinal tract. The number of patients of Crohn's disease is increasing in Japan. Symptoms of Crohn's disease include intestinal stenosis, longitudinal ulcers, and fistulae. Optical endoscope cannot pass through intestinal stenosis in some cases. We propose a new CAD system using abdominal fecal tagging CT images for efficient diagnosis of Crohn's disease. The system displays virtual unfolded (VU), virtual endoscopic, curved planar reconstruction, multi planar reconstruction, and outside views of both small and large intestines. To generate the VU views, we employ a small and large intestines extraction method followed by a simple electronic cleansing method. The intestine extraction is based on the region growing process, which uses a characteristic that tagged fluid neighbor air in the intestine. The electronic cleansing enables observation of intestinal wall under tagged fluid. We change the height of the VU views according to the perimeter of the intestine. In addition, we developed a method to enhance the longitudinal ulcer on views of the system. We enhance concave parts on the intestinal wall, which are caused by the longitudinal ulcer, based on local intensity structure analysis. We examined the small and the large intestines of eleven CT images by the proposed system. The VU views enabled efficient observation of the intestinal wall. The height change of the VU views helps finding intestinal stenosis on the VU views. The concave region enhancement made longitudinal ulcers clear on the views.

Drainage systems must be designed in a way to minimize undesired problems such as decrease in hydraulic capacity of the channel, blockage and transport of pollutants due to deposition of sediment. Channel design considering self-cleansing criteria are used to solve the sedimentation problem. Incipient deposition is one of the non-deposition self-cleansing design criteria that can be used as a conservative method for channel design. Experimental studies have been carried out in five different cross-section channels, namely trapezoidal, rectangular, circular, U-shape and V-bottom. Experiments were performed in a tilting flume using four different sizes of sands as sediment in nine different channel bed slopes. Two well-known methods, namely the Novak & Nalluri and Yang methods are considered for the analysis of sediment motion. Equations developed using experimental data are found to be in agreement with the literature. It is concluded that the design velocity depends on the shape of the channel cross-section. Rectangular and V-bottom channels need lower and higher incipient deposition velocities, respectively, in comparison with other channels.

Efficacy of dry-ice blasting in preventive maintenance of auto robotic assemblies

Welding robots are extensively applied in the automotive assemblies and `Spot Welding' is the most common welding application found in the auto stamping assembly manufacturing. Every manufacturing process is subject to variations - with resistance welding, these include; part fit up, part thickness variations, misaligned electrodes, variations in coating materials or thickness, sealers, weld force variations, shunting, machine tooling degradation; and slag and spatter damage. All welding gun tips undergo wear; an elemental part of the process. Though adaptive resistance welding control automatically compensates to keep production and quality up to the levels needed as gun tips undergo wear so that the welds remain reliable; the system cannot compensate for deterioration caused by the slag and spatter on the part holding fixtures, sensors, and gun tips. To cleanse welding robots of slag and spatter, dry-ice blasting has proven to be an effective remedy. This paper describes Spot welding process, analyses the slag and spatter formation during robotic welding of stamping assemblies, and concludes that the dry ice blasting process's utility in cleansing of welding robots in auto stamping plant operations is paramount and exigent.

Optimal bowel preparation is vital for the efficacy and safety of colonoscopy. The inconvenience, discomfort, required consumption of large volumes of product, and potential adverse effects associated with some bowel preparations deter patients from colonoscopy and may provide inadequate cleansing. A dual-action, non-phosphate, natural orange-flavored, low-volume preparation containing sodium picosulfate and magnesium citrate (P/MC) is currently being reviewed for bowel cleansing. This was a phase 3, randomized, multicenter, assessor-blinded, prespecified non-inferiority, head-to-head study to investigate the efficacy, safety, and tolerability of day-before administration of P/MC vs. 2L polyethylene glycol solution and two 5-mg bisacodyl tablets (2L PEG-3350 and bisacodyl tablets (HalfLytely and Bisacodyl Tablets Bowel Prep Kit)) in adult patients preparing for colonoscopy (SEE CLEAR II Study). The primary objective of the study was to demonstrate the non-inferiority of P/MC to 2L PEG-3350 and bisacodyl tablets in overall colon cleansing using a modified Aronchick scale. In addition, efficacy in the ascending, mid (transverse and descending), and recto-sigmoid segments of colon was evaluated using a modified Ottawa scale. Patient acceptability and tolerability of the bowel preparations were assessed via a standard questionnaire. Safety was assessed based on the monitoring of adverse events (AEs) and meaningful findings on clinical evaluations including physical examinations, vital sign measurements, and electrocardiograms (ECGs). A total of 603 patients were randomized to receive either P/MC (n = 300) or 2L PEG-3350 and bisacodyl tablets (n = 303). Based on the Aronchick scale, successful overall cleansing was similar in patients receiving P/MC (83.0%) and patients receiving 2L PEG-3350 and bisacodyl tablets (79.7%). P/MC demonstrated non-inferiority to 2L PEG-3350 and bisacodyl tablets in overall cleansing of the colon, as measured by the Aronchick scale. Similarly, the efficacy of P/MC, as measured by the Ottawa scale, was non-inferior to 2L PEG-3350 and bisacodyl tablets in cleansing the ascending, mid, and recto-sigmoid segments of the colon. Patient-reported acceptability and tolerability for each item examined on the questionnaire was significantly greater for P/MC compared with 2L PEG-3350 and bisacodyl tablets (P<0.0001).Treatment-emergent AEs related to the bowel preparation reported by 1% of patients receiving P/MC or 2L PEG-3350 and bisacodyl tablets were nausea (3.0% vs. 4.3%), vomiting (1.4% vs. 2.0%), and headache (2.7% vs. 1.7%). No clinically meaningful changes were noted in either treatment arm in data collected from physical examinations, vital sign measurements, and ECGs. When administered as a day-before dose, the bowel cleansing effects of P/MC were non-inferior compared with 2L PEG-3350 and bisacodyl tablets using the clinician-rated Aronchick and Ottawa scales. Treatment acceptability was significantly more favorable in patients receiving P/MC than in patients receiving 2L PEG-3350 and bisacodyl tablets.

Congenital cytomegalovirus (CMV) transmission can occur when women acquire CMV while pregnant. Infection control guidelines may reduce risk for transmission. We studied the duration of CMV survival after application of bacteria to the hands and after transfer from the hands to surfaces and the effectiveness of cleansing with water, regular and antibacterial soaps, sanitizer, and diaper wipes. Experiments used CMV AD169 in saliva at initial titers of 1 × 10(5) infectious particles/ml. Samples from hands or surfaces (points between 0 and 15 min) were placed in culture and observed for at least 2 weeks. Samples were also tested using CMV real-time PCR. After application of bacteria to the hands, viable CMV was recovered from 17/20 swabs at 0 min, 18/20 swabs at 1 min, 5/20 swabs at 5 min, and 4/20 swabs at 15 min. After transfer, duration of survival was at least 15 min on plastic (1/2 swabs), 5 min on crackers and glass (3/4 swabs), and 1 min or less on metal and cloth (3/4 swabs); no viable virus was collected from wood, rubber, or hands. After cleansing, no viable virus was recovered using water (0/22), plain soap (0/20), antibacterial soap (0/20), or sanitizer (0/22). Viable CMV was recovered from 4/20 hands 10 min after diaper wipe cleansing. CMV remains viable on hands for sufficient times to allow transmission. CMV may be transferred to surfaces with reduced viability. Hand-cleansing methods were effective at eliminating viable CMV from hands.

2016-07-13

Bowel preparation for colonoscopy is a key quality indicator that impacts on all aspects of the procedure, such as patient comfort, diagnostic yield, and adverse events. Although most laxative regimens currently employed have been compared in a multitude of settings, the optimal preparation regimen still remains an open question. Recent studies have focused on developing new regimens by modifying dosage, timing of administration or by combining laxatives with synergic mechanisms of action with the purpose of increasing patient tolerability while maximizing bowel cleansing. Several low-volume preparations and combinations of laxatives and adjunctive medication have shown promise in delivering both adequate preparation of the colon and good patient tolerability. Also, we have gained a better understanding of the influence of patient-related factors such as health literacy and education on the quality of bowel preparation. Although several novel regimens have been tested in recent trials, it remains unclear which, if any, of these bowel preparations can replace the standard bowel cleansing regimens in clinical practice. Also, further data are required on how to improve bowel cleansing by choosing the appropriate regimen for the individual patient.

Silver ionization water purification technology was originally developed for Apollo spacecraft. It was later used to cleanse swimming pools and has now been applied to industrial cooling towers and process coolers. Sensible Technologies, Inc. has added two other technologies to the system, which occupies only six square feet. It is manufactured in three capacities, and larger models are custom built on request. The system eliminates scale, corrosion, algae, bacteria and debris, and because of the NASA technology, viruses and waterborne bacteria are also destroyed. Applications include a General Motors cooling tower, amusement parks, ice manufacture and a closed-loop process cooling system.

Stennis Space Center's aquaculture research program has led to an attractive wastewater treatment for private homes. The system consists of a septic tank or tanks for initial sewage processing and a natural secondary treatment facility for further processing of septic tanks' effluent, consisting of a narrow trench, which contains marsh plants and rocks, providing a place for microorganisms. Plants and microorganisms absorb and digest, thus cleansing partially processed wastewater. No odors are evident and cleaned effluent may be discharged into streams or drainage canals. The system is useful in rural areas, costs about $1,900, and requires less maintenance than mechanical systems.

Metal pins are used to apply skeletal traction or external fixation devices in the management of orthopaedic fractures. These percutaneous pins protrude through the skin, and the way in which they are treated after insertion may affect the incidence of pin site infection. This review set out to summarise the evidence of pin site care on infection rates. To assess the effect on infection rates of different methods of cleansing and dressing orthopaedic percutaneous pin sites. In September 2013, for this third update, we searched the Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. We evaluated all randomised controlled trials (RCTs) that compared the effect on infection and other complication rates of different methods of cleansing or dressing orthopaedic percutaneous pin sites. Two review authors independently assessed the citations retrieved by the search strategies for reports of relevant RCTs, then independently selected trials that satisfied the inclusion criteria, extracted data and undertook quality assessment. A total of eleven trials (572 participants) were eligible for inclusion in the review but not all participants contributed data to each comparison. Three trials compared a cleansing regimen (saline, alcohol, hydrogen peroxide or antibacterial soap) with no cleansing (application of a dry dressing), three trials compared alternative sterile cleansing solutions (saline, alcohol, peroxide, povidone iodine), three trials compared methods of cleansing (one trial compared identical pin site care performed daily or weekly and the two others compared sterile with non sterile techniques), one trial compared daily pin site care with no care and six trials compared different dressings (using different solutions/ointments and dry and impregnated gauze or sponges). One small blinded study of 38 patients found that the risk of pin site infection was significantly reduced with polyhexamethylene biguanide (PHMB) gauze when compared to plain gauze (RR 0.23, 95% CI 0.12 to 0.44) (infection rate of 1% in the PHMB group and 4.5% in the control group) but this study was at high risk of bias as the unit of analysis was observations rather than patients. There were no other statistically significant differences between groups in any of the other trials. The available trial evidence was not extensive, was very heterogeneous and generally of poor quality, so there was insufficient evidence to be able to identify a strategy of pin site care that minimises infection rates. Adequately-powered randomised trials are required to examine the effects of different pin care regimens, and co-interventions - such as antibiotic use - and other extraneous factors must be controlled in the study designs.

Getting ready for a colonoscopy is difficult and involves many steps. Information given to patients is very important for adherence to treatment. We created a novel smart phone application (SPA) aimed to increase bowel preparation quality and patient satisfaction. We carried out a prospective, endoscopist-blinded, randomized, controlled trial. We enrolled 260 outpatient (58% female, age range 21-75 years) owners of a smartphone. Patients were allocated to two different protocols: instructions provided by SPA (SPA group; n = 108) or written instructions with visual aids (control group; n = 152). All procedures were carried out in the afternoon and patients received the same purgative regimen (2 L polyethylene glycol (PEG) solution plus ascorbic acid), in a full-dose same-day regimen. The study was designed to detect an improvement in quality of bowel preparation using the Harefield Cleansing Scale (HCS) scale. Effect of protocol on patient satisfaction was assessed with a specific questionnaire at the time of colonoscopy. Proportion of patients who obtained successful bowel preparation for colonoscopy (HCS A or B) was significantly higher in the SPA group than in the control group (100% vs 96.1%, respectively; P = 0.037). Mean global HCS scores were similar in both groups. Patient-reported tolerability and overall experience with the prescribed bowel preparation were significantly higher for the SPA group than for the control group. Successful cleansing and patient acceptability with the use of SPA were superior to written instructions in outpatients submitted for colonoscopy using 2 L PEG solution plus ascorbic acid. © 2015 The Authors.

A review of current issues underlying colon cleansing before colonoscopy

Hookey, Lawrence C; Vanner, Stephen

2007-01-01

The present review examines four current issues related to the efficacy, patient tolerance and safety of the following bowel cleansing agents: oral sodium phosphate (NaP), polyethylene glycol (PEG) and magnesium citrate (Pico-Salax, Ferring Pharmaceuticals Inc, Canada), an agent recently made available in Canada. MedLine and PubMed databases were systematically searched to identify studies related to the efficacy of altered PEG solutions combined with adjunct treatments; the efficacy, tolerability and safety of Pico-Salax; the association between nephrocalcinosis, and chronic renal failure and oral NaP use; and the role of diet. Although lower volume PEG solutions combined with adjuvant agents were generally associated with better patient tolerance, their efficacy was varied and interpretation of this end point is complicated by study design issues. There are very few reported studies of Pico-Salax, and as a result, there are insufficient data to draw conclusions about the efficacy of this agent. The available data suggest that Pico-Salax may be better tolerated by patients, than oral NaP and PEG solutions. There is a paucity of hemodynamic monitoring data pre- and postadministration, but the available data suggests that this small-volume osmotic agent could cause subclinical contraction of the intravascular space. Recent case reports suggest an association between nephrocalcinosis and oral NaP ingestion, but to date, these reports have been confined to a single centre. Preliminary studies suggest that this is not a widespread problem, but more studies are needed. There are only a few studies examining diet and patient tolerability, but they do suggest that diet may be liberalized with some cleansing regimens to enhance tolerability without decreasing efficacy. The present review highlights current controversies and advances in colon cleansing before colonoscopy, and also identifies areas for further study. PMID:17299615

Evaluating cleansing effects on trace elements and stable isotope values in feathers of oiled birds.

Feathers of seabirds are widely used as a nondestructive tissue for pollution monitoring of trace elements, as well as convenient samples for trophic ecology studies by means of stable isotope analysis (SIA). Nevertheless, feathers can be occasionally impregnated with oil from deliberate ship discharges and from massive oil spill accidents. The feather structure makes them effective traps for particles and are subject to external contamination. It is unknown to what extent the oil adhered to feathers can change trace element concentrations or stable isotope signatures. This study has two primary objectives: (1) to assess if there are differences between trace element concentrations and stable isotope signatures of oiled and clean feathers, and (2) to determine if the cleansing of oiled feathers using commonly applied techniques such as sodium hydroxide (NaOH) washes in combination with an organic solvent (hexane) is more effective than using NaOH alone. In order to do this, we analysed trace elements (Se, Hg, Pb, Cu and Zn) and stable isotopes (delta(13)C and delta(15)N) of individual feathers of yellow-legged gulls (Larus michahellis) which were affected by the 2002 Prestige oil spill in Galicia (NW Spain). Two sets of feathers were analysed, one group were oil-free (Control group) and the other had oil adhered to its surface (Oiled group). We expected to find differences between control and oiled feathers when cleaning exclusively with NaOH and no differences when using hexane. Our results did not show significant differences between Control and Oiled groups as a consequence of the cleansing method used. Unexpectedly, the additional cleansing with hexane resulted in decreasing selenium concentrations and increasing zinc and delta(15)N values in all groups of feathers.

The ideal preparation regimen for pediatric colonoscopy remains elusive, and available preparations continue to represent a challenge for children. The aim of this study was to compare the efficacy, safety, tolerability, and acceptance of 4 methods of bowel cleansing before colonoscopy in children. This randomized, investigator-blinded, noninferiority trial enrolled all children aged 2 to 18 years undergoing elective colonoscopy in a referral center for pediatric gastroenterology. Patients were randomly assigned to receive polyethylene glycol (PEG) 4000 with simethicon (PEG-ELS group) or PEG-4000 with citrates and simethicone plus bisacodyl (PEG-CS+Bisacodyl group), or PEG 3350 with ascorbic acid (PEG-Asc group), or sodium picosulfate plus magnesium oxide and citric acid (NaPico+MgCit group). Bowel cleansing was evaluated according to the Boston Bowel Preparation Scale. The primary end point was overall colon cleansing. Tolerability, acceptability, and compliance were also evaluated. Two hundred ninety-nine patients were randomly allocated to the 4 groups. In the per-protocol analysis, PEG-CS+Bisacodyl, PEG-Asc, and NaPico+MgCit were noninferior to PEG-ELS in bowel-cleansing efficacy of both the whole colon (P = .910) and colonic segments. No serious adverse events occurred in any group. Rates of tolerability, acceptability, and compliance were significantly higher in the NaPico+MgCit group. Low-volume PEG preparations (PEG-CS+Bisacodyl, PEG-Asc) and NaPico+MgCit are noninferior to PEG-ELS in children, representing an attractive alternative to high-volume regimens in clinical practice. Because of the higher tolerability and acceptability profile, NaPico+MgCit would appear as the most suitable regimen for bowel preparation in children.

A new sulfate-free polyethylene glycol electrolyte lavage solution (SF-ELS) for colonoscopy was formulated to taste better and have less net water and electrolyte secretion and absorption than a standard polyethylene glycolelectrolyte lavage solution (PEG-ELS). At two centers, 157 patients were prospectively randomized to receive SF-ELS or PEG-ELS to assess adequacy of preparation, patient tolerance, weight changes, and various hematologic and biochemical parameters. Physician assessment of colon cleansing showed no difference between those patients receiving SF-ELS (N = 74) or PEG-ELS (N = 78). Eighty-two percent of all preps were found to be "clinically acceptable." Subjects receiving SF-ELS had significantly less fullness and cramps, while PEG-ELS subjects reported less nausea. There was no difference between groups for vomiting, overall discomfort, or willingness to repeat the preparation received. Eighty percent of all patients would repeat the randomized cleansing methods. There were no clinically significant changes in weight or assessed laboratory parameters, with the exception of potassium where PEG-ELS patients had an mean decrease of 0.22 mEq/liter vs. 0.01 mEq/liter for SF-ELS (p less than or equal to 0.01). Patient taste questionnaires in those patients expressing a preference showed a preference for SF-ELS (76.6%) over PEG-ELS (23.4%) (p less than or equal to 0.001). Thirty-two (22.5%) of total respondents indicated no preference. We conclude that SF-ELS when compared with PEG-ELS is similarly a safe and effective method of colon cleansing for colonoscopy that is well tolerated. Patients prefer the taste of the new solution.

A new mouldable seal, Brava® Protective Seal, was evaluated by patients on aspects related to residue, durability, and preference. A total of 135 patients from four countries participated (Denmark, Germany, Japan and the USA) and the new product was compared to the patients' usual pouching systems. Less residue and easier skin cleansing was observed, which may benefit patient quality of life. The possible benefits of less residue for peristomal skin health need further investigation.

Current endodontic therapy involves debridement and disinfection of the root canal by means of mechanical instrumentation and chemical irrigation. However, several studies have shown that these techniques fail to achieve complete cleansing. Recently, lasers have been suggested for use within root canals. This study was conducted to determine the efficacy of Holmium:YAG laser irradiation in removing intracanal debris and smear layer. Root canal surfaces of freshly-extracted human teeth were exposed to pulsed Ho:YAG laser radiation. Subsequently, laser induced structural changes were investigated using scanning electron microscopy. Temperature measurements during irradiation were performed by means of thermocouples. The result of this survey give a preliminary indication of the ability of the Ho:YAG laser to improve current endodontic treatment survey give a preliminary indication of the ability of the Ho:YAG laser to improve current endodontic treatment modalities. However, limitations exist with regard to circumscribed and well-quantified irradiation of root canal surfaces, due to the lack of perpendicular delivery of the laser beam. Additional studies will be required to develop suitable optical transmission systems, in order to achieve complete cleansing and to avoid damage to the periradicular tissues, respectively.

Alertness, mood, and math computations were assessed in 11 healthy adults who sniffed a cosmetic cleansing gel with lavender floral blend aroma, developed to be relaxing using Mood Mapping. EEG patterns and heart rate were also recorded before, during, and after the aroma session. The lavender fragrance blend had a significant transient effect of improving mood, making people feel more relaxed, and performing the math computation faster. The self-report and physiological data are consistent with relaxation profiles during other sensory stimuli such as massage and music, as reported in the literature. The data suggest that a specific cosmetic fragrance can have a significant role in enhancing relaxation.

Purpose. This study evaluated the effects of using a newly developed eye cleansing formulation (Eye Shampoo) to cleanse the eyelids for 4 weeks in a parallel-group comparative study in women with chronic eye discomfort caused by heavy use of eye makeup and poor eye hygiene habits. Methods. Twenty women participants who met the inclusion criteria were randomly allocated to 2 groups comprising 10 participants each. The participants were asked to use either artificial tears alone or artificial tears in conjunction with Eye Shampoo for 4 weeks. The participants answered the questionnaire again and were reexamined, and changes in symptoms within each group and variations of symptoms between the two groups were statistically analyzed. Results. In the group using only artificial tears, improvements in subjective symptoms but not in ophthalmologic examination results were found. In the group using Eye Shampoo together with artificial tears, significant improvements were observed in the subjective symptoms, meibomian orifice obstruction, meibum secretion, tear breakup time, and superficial punctate keratopathy. Conclusion. In patients with chronic eye discomfort thought to be caused by heavy eye makeup, maintaining eyelid hygiene using Eye Shampoo caused a marked improvement in meibomian gland blockage and dry eye symptoms.

An oil-in-water cleansing emulsion containing calixarene molecule, an actinide specific chelating agent, was formulated in order to improve the decontamination of uranium from the skin. Commonly commercialized cosmetic ingredients such as surfactants, mineral oil, or viscosifying agents were used in preparing the calixarene emulsion. The formulation was characterized in terms of size and apparent viscosity measurements and then was tested for its ability to limit uranyl ion permeation through excoriated pig-ear skin explants in 24-h penetration studies. Calixarene emulsion effectiveness was compared with two other reference treatments consisting of DTPA and EHBP solutions. Application of calixarene emulsion induced the highest decontamination effect with an 87% decrease in uranium diffusion flux. By contrast, EHBP and DTPA solutions only allowed a 50% and 55% reduction of uranium permeation, respectively, and had the same effect as a simple dilution of the contamination by pure water. Uranium diffusion decrease was attributed to uranyl ion-specific chelation by calixarene within the formulation, since no significant effect was obtained after application of the same emulsion without calixarene. Thus, calixarene cleansing emulsion could be considered as a promising treatment in case of accidental contamination of the skin by highly diffusible uranium compounds.

Purpose. This study evaluated the effects of using a newly developed eye cleansing formulation (Eye Shampoo) to cleanse the eyelids for 4 weeks in a parallel-group comparative study in women with chronic eye discomfort caused by heavy use of eye makeup and poor eye hygiene habits. Methods. Twenty women participants who met the inclusion criteria were randomly allocated to 2 groups comprising 10 participants each. The participants were asked to use either artificial tears alone or artificial tears in conjunction with Eye Shampoo for 4 weeks. The participants answered the questionnaire again and were reexamined, and changes in symptoms within each group and variations of symptoms between the two groups were statistically analyzed. Results. In the group using only artificial tears, improvements in subjective symptoms but not in ophthalmologic examination results were found. In the group using Eye Shampoo together with artificial tears, significant improvements were observed in the subjective symptoms, meibomian orifice obstruction, meibum secretion, tear breakup time, and superficial punctate keratopathy. Conclusion. In patients with chronic eye discomfort thought to be caused by heavy eye makeup, maintaining eyelid hygiene using Eye Shampoo caused a marked improvement in meibomian gland blockage and dry eye symptoms.

Developing New Methods for Microsampling and Sm/Nd Dating of Zoned Garnet

Garnets provide one of the Earth Science community's most useful tools for studying rates, duration and timing of crustal processes. In this study we describe new techniques for fine sampling of multiple growth zones of garnet and Sm/Nd dating of each individual zone. We test these techniques on large (>5cm) garnets from a shear zone in the Tauern Window of Austria where we seek to quantify the growth history of garnet in a manner similar to dating tree rings. Microsampling permits a more precise quantification of duration, episodicity and kinetics of metamorphic reactions. Past studies of garnet growth duration - based on core and rim garnet ages - have been limited by sampling methods for extracting discrete, and accurate, growth zones. Modeling of radial growth symmetry in garnet shows that previous studies may underestimate garnet growth duration by as much as 50%. We are able to dramatically improve microsampling by using microdrilling guided by chemical maps of the garnet composition. This provides much improved precision and accuracy in sampling. By using chemical mapping of the garnet we can be sure that we are correctly sampling narrow (~500 micron wide) growth (i.e. age) zones rather than smearing and averaging multiple growth zones together. In principle, tens of growth zones (and ages) spanning the entire interval of garnet growth may be sampled and resolved. Microdrilled domains, the results of which are an ultrafine powder, are drilled and collected in water. Due to the adverse geochronological effect of unavoidable micro-inclusions in garnet, we have tested several partial dissolution techniques to cleanse the garnet of inclusions and yield higher 147Sm/144Nd and hence, more precise ages. Analysis of a finely crushed bulk Tauern Window garnet sample after HF/HClO3 cleansing indicates that 147Sm/144Nd at least as high as 0.89 is attainable in this particular sample, but cleansing efforts on microdrilled powders have thus far failed to yield such high ratios suggesting that the powders respond in unexpectedly different ways to our standard garnet cleansing procedures. Preliminary Sm/Nd age analysis of bulk garnet confirms a ~25Ma age for garnet growth. Progress in our inclusion cleansing procedures on microdrilled powders will be reported.

AIM To assess the cleansing efficacy and safety of a new Colon capsule endoscopy (CCE) bowel preparation regimen. METHODS This was a multicenter, prospective, randomized, controlled study comparing two CCE regimens. Subjects were asymptomatic and average risk for colorectal cancer. The second generation CCE system (PillCam® COLON 2; Medtronic, Yoqneam, Israel) was utilized. Preparation regimens differed in the 1st and 2nd boosts with the Study regimen using oral sulfate solution (89 mL) with diatrizoate meglumine and diatrizoate sodium solution (“diatrizoate solution”) (boost 1 = 60 mL, boost 2 = 30 mL) and the Control regimen oral sulfate solution (89 mL) alone. The primary outcome was overall and segmental colon cleansing. Secondary outcomes included safety, polyp detection, colonic transit, CCE completion and capsule excretion ≤ 12 h. RESULTS Both regimens had similar cleansing efficacy for the whole colon (Adequate: Study = 75.9%, Control = 77.3%; P = 0.88) and individual segments. In the Study group, CCE completion was superior (Study = 90.9%, Control = 76.9%; P = 0.048) and colonic transit was more often < 40 min (Study = 21.8%, Control = 4%; P = 0.0073). More Study regimen subjects experienced adverse events (Study = 19.4%, Control = 3.4%; P = 0.0061), and this difference did not appear related to diatrizoate solution. Adverse events were primarily gastrointestinal in nature and no serious adverse events related either to the bowel preparation regimen or the capsule were observed. There was a trend toward higher polyp detection with the Study regimen, but this did not achieve statistical significance for any size category. Mean transit time through the entire gastrointestinal tract, from ingestion to excretion, was shorter with the Study regimen while mean colonic transit times were similar for both study groups. CONCLUSION A CCE bowel preparation regimen using oral sulfate solution and diatrizoate solution as a boost agent is effective, safe, and achieved superior CCE completion. PMID:29358870

AIM: To evaluate the efficacy, tolerability, acceptability and feasibility of bisacodyl plus low volume polyethyleneglycol-citrate-simeticone (2-L PEG-CS) taken the same day as compared with conventional split-dose 4-L PEG for late morning colonoscopy. METHODS: Randomised, observer-blind, parallel group, comparative trial carried out in 2 centres. Out patients of both sexes, aged between 18 and 85 years, undergoing colonoscopy for diagnostic investigation, colorectal cancer screening or follow-up were eligible. The PEG-CS group received 3 bisacodyl tablets (4 tablets for patients with constipation) at bedtime and 2-L PEG-CS in the morning starting 5 h before colonoscopy. The control group received a conventional 4-L PEG formulation given as split regimen; the morning dose was taken with the same schedule of the low volume preparation. The Ottawa Bowel Preparation Scale (OBPS) score was used as the main outcome measure. RESULTS: A total of 164 subjects were enrolled and 154 completed the study; 78 in the PEG-CS group and 76 in the split 4-L PEG group. The two groups were comparable at baseline. The OBPS score in the PEG-CS group (3.09 ± 2.40) and in the PEG group (2.39 ± 2.55) were equivalent (difference +0.70; 95%CI: -0.09-1.48). This was confirmed by the rate of successful bowel cleansing in the PEG-CS group (89.7%) and in the PEG group (92.1%) (difference -2.4%; 95%CI: -11.40- 6.70). PEG-CS was superior in terms of mucosa visibility compared to PEG (85.7% vs 72.4%, P = 0.042). There were no significant differences in caecum intubation rate, time to reach the caecum and withdrawal time between the two groups. The adenoma detection rate was similar (PEG-CS 43.6% vs PEG 44.7%). No serious adverse events occurred. No difference was found in tolerability of the bowel preparations. Compliance was equal in both groups: more than 90% of subjects drunk the whole solution. Willingness to repeat the same bowel preparations was about 90% for both regimes. CONCLUSION: Same-day PEG-CS is feasible, effective as split-dose 4-L PEG for late morning colonoscopy and does not interfere with work and daily activities the day before colonoscopy. PMID:24044042

Adequate bowel preparation is essential before a colonoscopy, allowing us to make a proper examination of the entire mucosa. The ideal method of colon cleansing should be fast, safe, and get a proper cleaning with minimal discomfort for the patient. Today we have a wide variety of colon cleansing products, information sometimes becomes confused. A good colon preparation depends partly on correct choice of the same, but also upon dietary restriction. Knowledge of all these products, with their advantages and limitations, we can make a better selection for each patient, and although the efficacy is comparable, is the experience of the browser, patient preferences, and the degree of compliance with the instructions preparation, which greatly influence the results.

The authors used the SCID-DES (disorders of extreme stress) instrument to assess for personality change in Bosnian survivors of "ethnic cleansing." Twenty four refugees underwent systematic, trauma-focused, research assessments, including the SCID-DES interview. Overall, this group of Bosnian survivors had been severely traumatized as a result of the Serbian nationalists' genocide. However, no subject met diagnostic criteria for DES. The SCID-DES yields far lower rates of trauma-related personality change in Bosnian survivors of genocide than in adult survivors of prolonged early life traumas. Therefore, the DES construct may have better application to prolonged, interpersonal, early life traumas than to the prolonged, communal traumas of genocide.

Debris buildup on the bracket-wire interface can influence friction. Cleansing brackets with air-powder polishing can affect this process. The aim of this study was to evaluate the frictional force and amount of debris remaining on orthodontic brackets subjected to prophylaxis with air-powder polishing. Frictional force and debris buildup on the surface of 28 premolar brackets were evaluated after orthodontic treatment. In one hemiarch, each bracket was subjected to air-powder polishing (n = 14) for five seconds, while the contralateral hemiarch (n = 14) served as control. Mechanical friction tests were performed and images of the polished bracket surfaces and control surfaces were examined. Wilcoxon test was applied for comparative analysis between hemiarches at p < 0.05. Brackets that had been cleaned with air-powder polishing showed lower friction (median = 1.27 N) when compared to the control surfaces (median = 4.52 N) (p < 0.01). Image analysis showed that the control group exhibited greater debris buildup (median = 2.0) compared with the group that received prophylaxis with air-powder polishing (median = 0.5) (p < 0.05). Cleansing orthodontic brackets with air-powder polishing significantly reduces debris buildup on the bracket surface while decreasing friction levels observed during sliding mechanics.

The evolution of aerosols in the tropical upper troposphere/lower stratosphere between June 2006 and October 2009 is examined using the observations of the space borne CALIOP lidar aboard the CALIPSO satellite. Superimposed on several volcanic plumes and soot from an extreme biomass-burning event in 2009, the measurements reveal the existence of fast cleansing episodes of the lower stratosphere to altitudes as high as 20 km. The cleansing of the full 14-20km layer takes place within 1-4 months. Its coincidence with the maximum of convective activity in the southern tropics, suggests that the cleansing is the result of a large number of overshooting towers, injecting aerosol-poor tropospheric air into the lower stratosphere. The enhancements of aerosols at the tropopause level during the NH summer may be due to the same transport process but associated with intense sources of aerosols at the surface. Since, the tropospheric air flux derived from CALIOP observations during North Hemisphere winter is 5 20 times larger than the slow ascent by radiative heating usually assumed, the observations suggest that convective overshooting is a major contributor to troposphere-to-stratosphere transport with concommitant implications to the Tropical Tropopause Layer top height, chemistry and thermal structure.

Polyethylene glycol- (PEG-) based bowel preparations for colonoscopies are often poorly tolerated due to the large volumes of fluid intake required. We compared low-volume “modified” PEG + ascorbic acid (AJG522) with standard PEG with electrolytes (PEG + E) in addition to a stimulant laxative and an agent to improve bowel function for the bowel cleansing before colonoscopy to evaluate its efficacy, safety, and acceptability. Outpatients scheduled to undergo colonoscopy were randomized to receive either AJG522 or PEG + E. Bowel cleansing conditions were assessed via macroscopic fecal findings by blinded and independent investigators. A survey of the patients' feedback regarding the preparation was conducted by questionnaire. Successful cleansing was achieved in all cases, except for 4 cases in the PEG + E group, at 3 hours after taking the preparation. The fecal properties were significantly clearer in the AJG522 group than in the PEG + E group at 2 hours after taking each preparation (P = 0.013). Although the total liquid volume of the bowel preparation was not reduced, the AJG522 preparation could significantly reduce the required volume of the preparation (P < 0.0001). Moreover, the patients in the AJG522 group had better acceptability (P = 0.010). There were no significant differences in the safety profiles between groups (UMIN000013892). PMID:25688357

The World Health Organization recommends dry cord care for newborns but this recommendation may not be optimal in low resource settings where most births take place in an unclean environment and infections account for up to half of neonatal deaths. A previous trial in Nepal indicated that umbilical cord cleansing with 4.0% chlorhexidine could substantially reduce mortality and omphalitis risk, but policy changes await additional community-based data. The Projahnmo Chlorhexidine study was a three-year, cluster-randomized, community-based trial to assess the impact of three cord care regimens on neonatal mortality and omphalitis. Women were recruited mid-pregnancy, received a basic package of maternal and neonatal health promotion messages, and were followed to pregnancy outcome. Newborns were visited at home by local village-based workers whose areas were randomized to either 1) single- or 2) 7-day cord cleansing with 4.0% chlorhexidine, or 3) promotion of dry cord care as recommended by WHO. All mothers received basic messages regarding hand-washing, clean cord cutting, and avoidance of harmful home-base applications to the cord. Death within 28 days and omphalitis were the primary outcomes; these were monitored directly through home visits by community health workers on days 1, 3, 6, 9, 15, and 28 after birth. Due to report in early 2010, the Projahnmo Chlorhexidine Study examines the impact of multiple or single chlorhexidine cleansing of the cord on neonatal mortality and omphalitis among newborns of rural Sylhet District, Bangladesh. The results of this trial will be interpreted in conjunction with a similarly designed trial previously conducted in Nepal, and will have implications for policy guidelines for optimal cord care of newborns in low resource settings in Asia.

To compare the bowel cleansing efficacy, tolerability and acceptability of split 2-L polyethylene glycol (PEG)-citrate-simethicone (PEG-CS) plus bisacodyl (BIS) vs 4-L PEG for fecal occult blood test-positive screening colonoscopy. This was a randomised, observer-blind comparative study. Two hundred and sixty-four subjects underwent screening colonoscopy (mean age 62.5 ± 7.4 years, male 61.7%). The primary objective of the study was to compare the bowel cleansing efficacy of the two preparations. BIS plus PEG-CS: 3 tablets of 5-mg BIS at 16:00, PEG-CS 1-L at 19:00 and 1-L at 7:00, 4-L PEG: 3-L at 17:00, and 1-L at 7:00. Colonoscopy was carried out after 11:00, at least 3 h after the completion of bowel preparation. Bowel cleansing was evaluated using the Harefield Cleansing Scale. Bowel preparation was successful for 92.8% of subjects in the PEG-CS group and for 92.1% of subjects in the 4-L PEG (RR = 1.01; 95%CI: 0.94-1.08). BIS + PEG-CS was better tolerated than 4-L PEG. A greater rate of patients in the BIS + PEG-CS group had no difficulty and/or were willing to repeat the same preparation compared to split-dose 4-L PEG group. Subjects in the BIS + PEG-CS group rated the prep as good or satisfactory in 90.6% as compared to 77% in the 4-L PEG (P = 0.003). Subjects receiving BIS + PEG-CS stated they fully adhered to instructions drinking all the 2-L solution in 97.1% compared with 87.3% in the 4-L PEG (P = 0.003). BIS plus split 2-L PEG-CS was as effective as but better tolerated and accepted than split 4-L PEG for screening colonoscopy. This new procedure may increase the positive attitude and participation to colorectal cancer screening colonoscopy.

As one of the most common dermatologic chronic-recurrent disease, variable therapeutic options are available today for management of psoriasis. Although topical high potency corticosteroids, alone or in association with salicylic acid or vitamin D analogues, are still considered the best treatment, they do not seem to possess the capability for a long-term control of the disease or prevent recurrences, as their side effects are major contraindications for continuative use. The aim of this study was to investigate whether Dr. Michaels® product family is comparable to methylprednisolone aceponate (MPA) as a viable alternative treatment option for the treatment and management of stable chronic plaque psoriasis. Thirty adults (13 male, 17 female, mean age 40 years) with mild to severe stable chronic plaque psoriasis, were included in the study. Patients were advised to treat the lesions of the two sides of their body (left and right) with two different unknown modalities for 8 weeks; the pack of Dr. Michaels® products on the left side (consisting of a cleansing gel, an ointment and a skin conditioner) and a placebo pack on the right side, consisting of a cleansing gel, methylprednisolone ointment and a placebo conditioner. Assessment was done using the Psoriasis Activity Severity Index (PASI) scores before treatment and after 2, 4, 6 and 8 weeks. The results achieved with the Dr. Michaels® (Soratinex®) product family for the treatment of chronic plaque psoriasis were better than the results achieved with methylprednisolone aceponate (MPA), even though quicker resolution was achieved with the steroid with 45% of patients achieving resolution within 8-10 days in comparison to 5-6 weeks in the Dr. Michaels® (Soratinex®) group. Before therapy, the mean PASI score of the LHS in Dr. Michaels® (Soratinex®) group was 13.8±4.1 SD and 14.2±4.2 SD in the RHS methylprednisolone aceponate (MPA) group. After 8 weeks of treatment 62% of the Dr. Michaels® (Soratinex®) group had achieved resolution whilst in the methylprednisolone aceponate (MPA) group, the figure remained at 45%. The mean PASI score after 8 weeks of treatment was calculated and in the LHS Dr. Michaels® (Soratinex®) group it was 2.8±1.6 SD and 6.8±2.4 SD in the RHS methylprednisolone aceponate group. In the RHS -methylprednisolone aceponate (MPA) group, 22% of patients failed to respond to the treatment in comparison to 6% in the LHS Dr. Michaels® (Soratinex®) group. Based on the results of this study, Dr. Michaels® products are a more effective treatment option, with insignificant side effects, compared to local treatment with methylprednisolone aceponate (MPA).

Hand-cleansing products that are milder to the skin of health care personnel are being developed, but the available methodologies to appropriately evaluate these products and quantify differences are not generally being applied in well-controlled studies. Two randomized, blinded, bilateral comparison studies evaluated skin condition during use of 2 antiseptic hand preparation products: a new 1% chlorhexidine gluconate (CHG)/61% wt/wt ethanol antiseptic hand preparation in a unique emollient system for waterless/brushless application and a conventional 4% CHG antimicrobial product that is applied with water and a scrub brush. Trained technicians applied treatments 6 times (for a surgical scrub study) or 24 times (for a personnel handwash study) daily to the hands of healthy volunteers during 5 days of controlled washing. An expert grader evaluated skin for dryness, erythema, and roughness. Subjects completed a self-assessment questionnaire on skin condition. Transepidermal water loss was measured by an evaporimeter, and the skin surface hydration level was measured by an electrical conductance meter. Fifty-eight subjects were enrolled in the 2 studies and received both treatments. In general, skin treated with the waterless CHG/ethanol product scored significantly (P <.004) better on evaluations of visual dryness and erythema and showed greater improvement in the level of hydration (P <.003). In the health care personnel handwash study, transepidermal water loss was less than that for skin treated with the conventional CHG product (P <.002). Subject assessments showed similar results (total score, P <.007). All 3 approaches of expert grader evaluation, subject assessment, and instrumentation were in concordance, demonstrating that the waterless CHG/ethanol product was gentler to skin than the conventional CHG product.

The effect of denture cleansing solutions and multiple pulls on the retention of pink Locator patrices was studied. Five groups of pink Locator attachments (3.0 lb. Light Retention replacement patrix attachments; five in each group) were soaked for the equivalent of 6 months of clinical use in the following solutions: water (control), Efferdent, Polident Overnight, 6.15% sodium hypochlorite (NaOCL, 1:10 dilution), and Listerine mouthwash. A universal testing machine set at a 2 in/min crosshead speed was used to perform 548 pulls (548 cycles of insertion and removal). The reduction in load to dislodgement (retention) after the initial pull and the final pull and the percent reduction in retention after 6 months were compared between the groups using a one-way ANOVA followed by Tukey's Honestly Significant Difference (HSD) Test (α= 0.05). Denture cleansing solutions significantly reduced the retentive values of pink Locator attachments after the initial pull (F = 17.435, p < 0.0001). The retentive values of Efferdent, Listerine, Polident Overnight, and water were significantly higher than the retentive value of the attachments soaked in NaOCl. After 6 months of simulated use (548 pulls), the four denture cleansing solutions had significant effects on the retentive values of pink Locator attachments (F = 5.855, p = 0.003). The retentive values for attachments soaked in NaOCl (7.29 ± 1.0 N) were significantly lower than those of attachments soaked in Listerine (15.82 ± 4.7 N) and in Polident Overnight (14.41 ± 3.6 N). These cleansing solutions also had a significant effect on the percentage of retention lost (F = 3.271, p = 0.032). The loss of retention in attachments soaked in Listerine (29 ± 9%) was significantly lower than attachments soaked in water (53 ± 12%). The loss of retention in attachments soaked in Efferdent was 49 ± 9%; in Polident Overnight, 34 ± 18%; and in NaOCl, 42 ± 11%. There was no significant difference in the percentage of retention loss between water, Efferdent, NaOCl, and Polident Overnight. There was also no significant difference in the percentage of retention loss between Efferdent, NaOCl, Polident Overnight, and Listerine. NaOCl significantly decreased the retentive value of Locators. Therefore, it should not be routinely recommended for use as a denture cleanser. Listerine significantly increased the retention of the Locator attachments; however, it is premature to recommend Listerine for use as a denture cleanser. © 2011 by The American College of Prosthodontists.

Microplastic particles (MPPs; <5 mm) are found in skin cleansing soaps and are released into the environment via the sewage system. MPPs in the environment can sorb persistent organic pollutants (POPs) that can potentially be assimilated by organisms mistaking MPPs for food. Amphipods (Allorchestes compressa) exposed to MPPs isolated from a commercial facial cleansing soap ingested ≤45 particles per animal and evacuated them within 36 h. Amphipods were exposed to polybrominated diphenyl ether (PBDEs) congeners (BDE-28, -47, -99, -100, -153, -154, and -183) in the presence or absence of MPPs. This study has demonstrated that PBDEs derived from MPPs can be assimilated into the tissue of a marine amphipod. MPPs reduced PBDE uptake compared to controls, but they caused greater proportional uptake of higher-brominated congeners such as BDE-154 and -153 compared to BDE-28 and -47. While MPPs in the environment may lower PBDE uptake compared to unabsorbed free chemicals, our study has demonstrated they can transfer PBDEs into a marine organism. Therefore, MPPs pose a risk of contaminating aquatic food chains with the potential for increasing public exposure through dietary sources. This study has demonstrated that MPPs can act as a vector for the assimilation of POPs into marine organisms.

Successful colonoscopy depends on the insertion of the instrument to the cecum, a detailed examination, and minimal discomfort to the patient during the procedure. The aim of this study was to determine the effects of alverine citrate plus simethicone on the cecal intubation time, colonic spasm and bowel cleanliness. A prospective, randomized, controlled trial in a consecutive series of patients was conducted to compare alverine citrate as an antispasmodic agent for relaxation of spasm with elective colonoscopy. The drug used consisted of 60 mg alverine citrate plus 300 mg simethicone. Sodium phosphate soda and enema were recommended for bowel cleansing. During colonoscopy, spasticity, difficulty of the procedure, pain, and cleanliness of the colon were scored between 0-4. The time required to reach the cecum was recorded as minutes. Of 165 total patients, 83 and 82 patients were randomized as the drug group (mean age: 51.85+/-13.47 years) and control group (mean age: 51.68+/-16.28 years), respectively. There was a statistically significant difference between the groups in the mean time to reach the cecum in favor of the drug group (7.48+/-3.45 minutes vs. 6.20+/-3.24 minutes; p=0.02). The time to reach the cecum prolonged with an increase in pain score and difficulty score (p=0.0001 and p=0.001, respectively). Alverine citrate plus simethicone reduced the intubation time significantly by 19%, from 7.48 minutes to 6.20 minutes.

Poison ivy, oak, and sumac dermatitis identification, treatment, and prevention.

PubMed

Garner, L A

1999-05-01

Allergic contact dermatitis from poison ivy, oak, or sumac is common among people who work or exercise outdoors. The plants, classified in the genus Rhus or Toxicodendron, contain allergens that can cause reactions ranging from mild pruritus to severe urticaria or generalized maculopapular eruptions. Initial management includes cleansing, cold compresses, and, possibly, oral antihistamines for symptomatic relief. Topical corticosteroids are given for localized nonfacial eruptions; systemic corticosteroids are used for severe eruptions. Prevention involves avoiding contact with the plants and washing exposed skin within 2 hours.

Causality implies inflationary back-reaction

NASA Astrophysics Data System (ADS)

Basu, S.; Tsamis, N. C.; Woodard, R. P.

2017-07-01

There is a widespread belief among inflationary cosmologists that a local observer cannot sense super-horizon gravitons. The argument goes that a local observer would subsume super-horizon gravitons into a redefinition of his coordinate system. We show that adopting this view for pure gravity on de Sitter background leads to time variation in the Hubble parameter measured by a local observer. It also leads to a violation of the gravitational field equation R = 4Λ because that equation is obeyed by the full metric, rather than the one which has been cleansed of super-horizon modes.

A prospective randomized trial on the use of Coca-Cola Zero(®) vs water for polyethylene glycol bowel preparation before colonoscopy.

PubMed

2016-07-01

The study aimed to determine whether Coca-Cola (Coke) Zero is a safe and effective solvent for polyethylene glycol (PEG). Between December 2013 and April 2014, 209 healthy adults (115 men, 95 women) scheduled for elective colonoscopy were randomized to use either Coke Zero (n = 100) or drinking water (n = 109) with PEG as bowel preparation. Each patient received two sachets of PEG to dissolve in 2 l of solvent, to be completed 6 h before colonoscopy. Serum electrolytes were measured before and after preparation. Bowel cleanliness and colonoscopy findings were recorded. Palatability of solution, adverse effects, time taken to complete and willingness to repeat the preparation were documented via questionnaire. Mean palatability scores in the Coke Zero group were significantly better compared with the control group (2.31 ± 0.61 vs 2.51 ± 0.63, P = 0.019), with a higher proportion willing to use the same preparation again (55% vs 43%). The mean time taken to complete the PEG + Coke Zero solution was significantly faster (74 ± 29 min vs 86 ± 31 min, P = 0.0035). The quality of bowel cleansing was also significantly better in the Coke Zero group (P = 0.0297). There was no difference in the frequency of adverse events (P = 0.759) or the polyp detection rate (32% vs 31.2%). Consumption of either preparation did not significantly affect electrolyte levels or hydration status. Coke Zero is a useful alternative solvent for PEG. It is well tolerated, more palatable, leads to quicker consumption of the bowel preparation and results in better quality cleansing.

2009-01-01

Of the 4 million neonatal deaths and 500,000 maternal deaths that occur annually worldwide, almost 99% are in developing countries and one-third are associated with infections. Implementation of proven interventions and targeted research on a select number of promising high-impact preventative and curative interventions are essential to achieve Millennium Development Goals for reduction of child and maternal mortality. Feasible, simple, low-cost interventions have the potential to significantly reduce the mortality and severe morbidity associated with infection in these settings. Studies of chlorhexidine in developing countries have focused on three primary uses: 1) intrapartum vaginal and neonatal wiping, 2) neonatal wiping alone, and 3) umbilical cord cleansing. A study of vaginal wiping and neonatal skin cleansing with chlorhexidine, conducted in Malawi in the 1990s suggested that chlorhexidine has potential to reduce neonatal infectious morbidity and mortality. A recent trial of cord cleansing conducted in Nepal also demonstrated benefit. Although studies have shown promise, widespread acceptance and implementation of chlorhexidine use has not yet occurred. This paper is derived in part from data presented at a conference on the use of chlorhexidine in developing countries and reviews the available evidence related to chlorhexidine use to reduce mortality and severe morbidity due to infections in mothers and neonates in low-resource settings. It also summarizes issues related to programmatic implementation. PMID:17399714

Washing away your (good or bad) luck: physical cleansing affects risk-taking behavior.

PubMed

Xu, Alison Jing; Zwick, Rami; Schwarz, Norbert

2012-02-01

Many superstitious practices entail the belief that good or bad luck can be "washed away." Consistent with this belief, participants who recalled (Experiment 1) or experienced (Experiment 2) an episode of bad luck were more willing to take risk after having as opposed to not having washed their hands, whereas participants who recalled or experienced an episode of good luck were less willing to take risk after having as opposed to not having washed their hands. Thus, the psychological effects of physical cleansings extend beyond the domain of moral judgment and are independent of people's motivation: incidental washing not only removes undesirable traces of the past (such as bad luck) but also desirable ones (such as good luck), which people would rather preserve.

NASA environmental research has led to a plant-based air filtering system. Dr. B.C. Wolverton, a former NASA engineer who developed a biological filtering system for space life support, served as a consultant to Terra Firma Environmental. The company is marketing the BioFilter, a natural air purifier that combines activated carbon and other filter media with living plants and microorganisms. The filter material traps and holds indoor pollutants; plant roots and microorganisms then convert the pollutants into food for the plant. Most non-flowering house plants will work. After pollutants have been removed, the cleansed air is returned to the room through slits in the planter. Terra Firma is currently developing a filter that will also disinfect the air.

Gfatter, R; Hackl, P; Braun, F

1997-01-01

In adults the influence of cleansing preparations on the pH, fat content and hydration of the skin is well documented. Studies in newborn and small infants have not been reported. Our study aimed at examining whether similar effects can be ascertained in infants. Infants without skin disease, aged 2 weeks to 16 months, entered an open, controlled and randomized study. Ten infants each had skin washed with tap water (control group), liquid detergent (pH 5.5), compact detergent (pH 5.5) or alkaline soap (pH 9.5). The pH, fat content and hydration were measured before and 10 min after cleansing. Findings were statistically evaluated by parametric covariance analysis. The skin pH increased from an average of 6.60 after cleansing in all groups. The smallest increase (+0.19) was observed in the control group, the largest (+0.45) after washing with alkaline soap. After treatment with liquid or compact detergent, the increase of the pH was only 0.09 higher than for the control group. In comparison to the compact and liquid detergents, the alkaline soap group had a significantly higher increase in pH. The fat content (mean starting value: 4.34 micrograms/cm2) decreased after washing in all groups; the smallest effect was observed in the control group (decrease of 0.93 micrograms/cm2), the highest for the alkaline soap group (decrease of 4.81 micrograms/cm2). In comparison to the compact and liquid detergents, the alkaline soap group had a higher decrease in fat content. This difference was significant for compact detergents. No statistically significant differences were observed for hydration before versus after washing. Each cleansing agent, even normal tap water, influences the skin surface. The increase of the skin pH irritates the physiological protective 'acid mantle', changes the composition of the cutaneous bacterial flora and the activity of enzymes in the upper epidermis, which have an acid pH optimum. The dissolution of fat from the skin surface may influence the hydration status leading to a dry and squamous skin.

AIM: To compare the bowel cleansing efficacy, tolerability and acceptability of split 2-L polyethylene glycol (PEG)-citrate-simethicone (PEG-CS) plus bisacodyl (BIS) vs 4-L PEG for fecal occult blood test-positive screening colonoscopy. METHODS: This was a randomised, observer-blind comparative study. Two hundred and sixty-four subjects underwent screening colonoscopy (mean age 62.5 ± 7.4 years, male 61.7%). The primary objective of the study was to compare the bowel cleansing efficacy of the two preparations. Interventions: BIS plus PEG-CS: 3 tablets of 5-mg BIS at 16:00, PEG-CS 1-L at 19:00 and 1-L at 7:00, 4-L PEG: 3-L at 17:00, and 1-L at 7:00. Colonoscopy was carried out after 11:00, at least 3 h after the completion of bowel preparation. Bowel cleansing was evaluated using the Harefield Cleansing Scale. RESULTS: Bowel preparation was successful for 92.8% of subjects in the PEG-CS group and for 92.1% of subjects in the 4-L PEG (RR = 1.01; 95%CI: 0.94-1.08). BIS + PEG-CS was better tolerated than 4-L PEG. A greater rate of patients in the BIS + PEG-CS group had no difficulty and/or were willing to repeat the same preparation compared to split-dose 4-L PEG group. Subjects in the BIS + PEG-CS group rated the prep as good or satisfactory in 90.6% as compared to 77% in the 4-L PEG (P = 0.003). Subjects receiving BIS + PEG-CS stated they fully adhered to instructions drinking all the 2-L solution in 97.1% compared with 87.3% in the 4-L PEG (P = 0.003). CONCLUSION: BIS plus split 2-L PEG-CS was as effective as but better tolerated and accepted than split 4-L PEG for screening colonoscopy. This new procedure may increase the positive attitude and participation to colorectal cancer screening colonoscopy. PMID:24023492

To evaluate the effects of the various methods of small bowel preparation on the quality of visualization of the small bowel and the gastrointestinal transit time of capsule endoscopy (CE). Ninety patients referred for CE were prospectively randomized to three equal groups according to the preparation used: (a) a control group, in which patients were requested to drink 1 L of clear liquids only, 12 h before the examination; (b) a purgative group, in which patients were requested to ingest 1 L of a polyethylene glycol (PEG)/electrolyte solution only, 12 h before the examination; or (c) a purgative combined with simethicone group (P-S group), in which patients were requested to ingest 1 L of PEG, 12 h before the examination, and 300 mg of simethicone, 20 min before the examination. Effects of the different bowel preparations on the gastric transit time (GTT), small bowel transit time (SBTT), examination completion rate, quality of images of the entire small intestine, and cleansing of the proximal small bowel and distal ileum were evaluated. The number of patients with "adequate" cleansing of the entire small intestine was 17 in the P-S group, 12 in the purgative group, and seven in the control group (P= 0.002). The P-S group had significantly better image quality than the control group (P= 0.001). The P-S group had significantly better image quality for the proximal small bowel (segment A [Seg A]) than the control group (P= 0.0001). Both the P-S group (P= 0.0001) and the purgative group (P= 0.0002) had significantly better image quality for the distal ileum (segment B [Seg B]) than the control group; the P-S group had significantly better image quality than the purgative group as well (P= 0.0121). Gastrointestinal transit time was not different among the three groups, nor was the examination completion rate. Purgative bowel cleansing combined with simethicone before CE improved the quality of imaging of the entire small bowel as well as the visualization of the mucosa in the proximal and distal small intestine.

OBJECTIVE Hospital-based data from Africa suggest that newborn skin-cleansing with chlorhexidine may reduce neonatal mortality. Evaluation of this intervention in the communities where most births occur in the home has not been done. Our objective was to assess the efficacy of a 1-time skin-cleansing of newborn infants with 0.25% chlorhexidine on neonatal mortality. METHODS The design was a community-based, placebo-controlled, cluster-randomized trial in Sarlahi District in southern Nepal. Newborn infants were cleansed with infant wipes that contained 0.25% chlorhexidine or placebo solution as soon as possible after delivery in the home (median: 5.8 hours). The primary outcome was all-cause mortality by 28 days. After the completion of the randomized phase, all newborns in study clusters were converted to chlorhexidine treatment for the subsequent 9 months. RESULTS A total of 17 530 live births occurred in the enrolled sectors, 8650 and 8880 in the chlorhexidine and placebo groups, respectively. Baseline characteristics were similar in the treatment groups. Intention-to-treat analysis among all live births showed no impact of the intervention on neonatal mortality. Among live-born infants who actually received their assigned treatment (98.7%), there was a nonsignificant 11% lower neonatal mortality rate among those who were treated with chlorhexidine compared with placebo. Low birth weight infants had a statistically significant 28% reduction in neonatal mortality; there was no significant difference among infants who were born weighing ≥2500 g. After conversion to active treatment in the placebo clusters, there was a 37% reduction in mortality among low birth weight infants in the placebo clusters versus no change in the chlorhexidine clusters. CONCLUSIONS Newborn skin-wiping with chlorhexidine solution once, soon after birth, reduced neonatal mortality only among low birth weight infants. Evidence from additional trials is needed to determine whether this inexpensive and simple intervention could improve survival significantly among low birth weight infants in settings where home delivery is common and hygiene practices are poor.

Optimal Bowel Preparation for Video Capsule Endoscopy

PubMed Central

Song, Hyun Joo; Moon, Jeong Seop; Shim, Ki-Nam

2016-01-01

During video capsule endoscopy (VCE), several factors, such as air bubbles, food material in the small bowel, and delayed gastric and small bowel transit time, influence diagnostic yield, small bowel visualization quality, and cecal completion rate. Therefore, bowel preparation before VCE is as essential as bowel preparation before colonoscopy. To date, there have been many comparative studies, consensus, and guidelines regarding different kinds of bowel cleansing agents in bowel preparation for small bowel VCE. Presently, polyethylene glycol- (PEG-) based regimens are given primary recommendation. Sodium picosulphate-based regimens are secondarily recommended, as their cleansing efficacy is less than that of PEG-based regimens. Sodium phosphate as well as complementary simethicone and prokinetics use are considered. In this paper, we reviewed previous studies regarding bowel preparation for small bowel VCE and suggested optimal bowel preparation of VCE. PMID:26880894

We report a systematic review and meta-analysis of published randomised and quasi-randomised trials evaluating the efficacy of pre-operative skin antisepsis and cleansing techniques in reducing foot and ankle skin flora. The post-preparation culture number (Post-PCN) was the primary outcome. The data were evaluated using a modified version of the Cochrane Collaboration’s tool. We identified eight trials (560 participants, 716 feet) that met the inclusion criteria. There was a significant difference in the proportions of Post-PCN between hallux nailfold (HNF) and toe web spaces (TWS) sites: 0.47 vs 0.22, respectively (95% confidence interval (CI) 0.182937 to 0.304097; p < 0.0001). Meta-analyses showed that alcoholic chlorhexidine had better efficacy than alcoholic povidone-iodine (PI) at HNF sites (risk difference 0.19 (95% CI 0.08 to 0.30); p = 0.0005); a two-step intervention using PI scrub and paint (S&P) followed by alcohol showed significantly better efficacy over PI (S&P) alone at TWS sites (risk difference 0.13 (95% CI 0.02 to 0.24); p = 0.0169); and a two-step intervention using chlorhexidine scrub followed by alcohol showed significantly better efficacy over PI (S&P) alone at the combined (HNF with TWS) sites (risk difference 0.27 (95% CI 0.13 to 0.40); p < 0.0001). No significant difference was found between cleansing techniques.

A 6% Benzoyl Peroxide Foaming Cloth Cleanser Used in the Treatment of Acne Vulgaris

PubMed Central

2009-01-01

Objective: The study was conducted to evaluate the product attributes of a new benzoyl peroxide-containing foaming cloth cleanser and to compare the overall patient satisfaction of this product with two currently available benzoyl peroxide acne products (6% benzoyl peroxide cleanser and 4% benzoyl peroxide wash). Design: This was a randomized, single-blind study. Setting: Two clinical trial sites. Participants: Male and female subjects (N=193) aged 17 to 30 years with a history of acne vulgaris were enrolled. Measures: Subjects initially cleansed their face with the benzoyl peroxide foaming cloth and then completed a product-attribute survey. Following an interval of five minutes or more, subjects cleansed their face again using one of two randomly assigned comparator benzoyl peroxide-containing cleansing products and then completed a comparative survey. Survey results were tabulated and a top-two box analysis was performed. Results: Following the use of the benzoyl peroxide-containing foaming cloth, 94 percent of the product-attribute responses were positive (p≤0.05). With respect to convenience, usability, and cosmetic elegance, the majority of subjects indicated a preference for the benzoyl peroxide foaming cloth compared to the 6% benzoyl peroxide cleanser and 4% benzoyl peroxide wash (for each, p≤0.05). There were no reports of adverse events. Conclusion: These attributes supporting preference for the benzoyl peroxide foaming cloth cleanser may improve patient satisfaction with topical acne treatment resulting in improved patient compliance.

Objectives: To assess the effect of cleansing treatments following saliva and blood contamination at different bonding stages to dentin. Materials and Methods: Labial surfaces of 168 permanent maxillary central incisors were ground flat exposing superficial dentin. Specimens were divided into: uncontaminated control (A), contamination after etching (B), contamination after adhesive application (C), contamination after adhesive polymerization (D). Groups were further subdivided according to cleansing treatments into: rinsing (B1, C1, D1), re-etching (B2, D3), sodium hypochlorite application (B3), ethyl alcohol application (C2), acetone application (C3), rinsing and rebonding (D2), re-etching and rebonding (D4). Composite microcylinders were bonded to treated substrates and shear loaded micro-shear bond strength (μSBS) until failure and treated surfaces were examined with scanning electron microscope. Debonded surfaces were classified as adhesive, cohesive or mixed failure. The data were analyzed using one-way ANOVA and Tukey's post hoc test. Results: The μSBS values were ranked as follow; Group B: A > B3 > B2 > B1 > B, Group C: A > C3 > C2 > C1 > C, Group D: A > D4 > D1 = D2 ≥ D3. Debonded surfaces showed adhesive failure in Group B while cohesive failure in Groups C and D. Conclusions: Cleansing treatments differ according to bonding step; re-etching then rebonding suggested if etched substrate or polymerized adhesive were contaminated while acetone application decontaminated affected unpolymerized adhesive.

Background and aim To evaluate the diagnostic accuracy of magnetic resonance colonography (MRC) without bowel cleansing in a screening population and compare the results to colonoscopy as a standard of reference. Methods 315 screening patients, older than 50 years with a normal risk profile for colorectal cancer, were included in this study. For MRC, a tagging agent (5.0% Gastrografin, 1.0% barium sulphate, 0.2% locust bean gum) was ingested with each main meal within 2 days prior to MRC. No bowel cleansing was applied. For the magnetic resonance examination, a rectal water enema was administered. Data collection was based on contrast enhanced T1 weighted images and TrueFISP images. Magnetic resonance data were analysed for image quality and the presence of colorectal lesions. Conventional colonoscopy and histopathological samples served as reference. Results In 4% of all colonic segments, magnetic resonance image quality was insufficient because of untagged faecal material. Adenomatous polyps >5 mm were detected by means of MRC, with a sensitivity of 83.0%. Overall specificity was 90.2% (false positive findings in 19 patients). However, only 16 of 153 lesions <5 mm and 9 of 127 hyperplastic polyps could be visualised on magnetic resonance images. Conclusions Faecal tagging MRC is applicable for screening purposes. It provides good accuracy for the detection of relevant (ie, adenomatous) colorectal lesions >5 mm in a screening population. However, refinements to optimise image quality of faecal tagging are needed. PMID:17341542

There is no consensus concerning small bowel preparation before capsule endoscopy (CE). This study evaluated the effects of 4 regimens on small bowel cleansing and diagnostic yield. Patients were randomly divided into 4 groups. Group A consumed a clear liquid diet after lunch on the day before CE, followed by overnight fasting. Group B took 250 mL 20% mannitol and 1 L 0.9% saline orally at 05:00 hours on the day of the procedure. In group C, the same regimen was taken at 20:00 hours on the day before and at 05:00 hours on the day of CE. In group D, in addition to the group C regimen, 20 mL oral simethicone was taken 30 minutes before CE. Two hundred patients were prospectively enrolled, and 7 were excluded from the final analysis because of incomplete small bowel transit. No significant difference was noted among the 4 groups for small bowel transit time. Bowel preparation in group D was significantly better than for the other regimens for overall cleansing of the proximal small bowel, and showed improved overall cleansing of the distal small bowel when compared with 10-hours overnight fasting. Pathological lesions of the proximal and distal small bowel were, respectively, achieved in 82 and 74 patients, mostly distributed in group D. Small bowel preparation that involves split-dose oral mannitol plus single-dose simethicone for CE can improve mucosal visualization and subsequent diagnostic yield when compared with 10-hours overnight fasting.

Staphylococcus aureus is known to form a biofilm and colonize on damaged skin of the hands. We investigated changes in the quantity of S aureus on the hands and changes in skin damage when using a hand-cleansing formulation with potassium oleate but without a sanitizer (formulation A), which is highly effective in removing S aureus biofilm and causes minimal skin damage. The participants (14 medical staff members) used 2 types of hand-cleansing formulations (formulations A and B), each for 4 weeks. S aureus of the hands was cultured from swab samples on agar plates. Surface of hands was measured using an ultraviolet light microscope. The quantity of S aureus after using formulation A for 4 weeks was 10(1.08 ± 0.05) CFU/mL, a statistically significant decrease from the quantity of S aureus (10(1.59 ± 0.19) CFU/mL) just before use (P = .029). Also, dryness of hand surfaces decreased. With formulation B, the quantity of S aureus did not significantly change from before to after use (P > .05). This presumably occurs because formulation A gently removes S aureus biofilm. Formulation A removed S aureus from the hands of participants, and skin damage on the hands improved.

Systematic review and meta-analysis: Sodium picosulphate with magnesium citrate as bowel preparation for colonoscopy

PubMed Central

Munsterman, Isabelle D; Eskes, Anne M; Maaskant, Jolanda M; van der Hulst, René

2016-01-01

Background An effective and tolerable bowel preparation is important to secure quality of colonoscopies. It remains unclear if sodium picosulphate with magnesium citrate (SPMC), which is considered a tolerable bowel preparation agent, is also an effective alternative for polyethylene glycol (PEG) and sodium phosphate (NaP). Aim The aim of this article is to compare effectiveness of SPMC to PEG and NaP through assessment of quality of bowel cleansing measured by validated tools. Methods We searched electronic databases up to January 2015. Only randomised controlled trials (RCTs) were included. Two authors independently performed selection of studies, risk of bias assessment and data extraction. Results Thirteen RCTs were included, with overall good quality, but large heterogeneity. SPMC had slightly better quality of bowel cleansing than PEG (pooled RR 1.06; 95% CI 1.02 to 1.11). In most trials SPMC was significantly better tolerated than PEG. There were no significant differences in effectiveness or tolerability between SPMC and NaP. Side effects were similar between agents, except for dizziness (pooled RR 1.71; 95% CI 1.32 to 2.21 in favour of PEG vs. SPMC) and vomiting (pooled RR 0.35; 95% CI 0.13 to 0.95 in favour of single-dose SPMC vs. split-dose). Conclusions SPMC is equally effective to NaP and little superior to PEG in terms of bowel cleansing. SPMC preparations were better tolerated than PEG preparations. SPMC may be considered as standard bowel preparation for colonoscopy. PMID:29163958

Skin cleansing preparations consisting of identical synthetic detergents but differing in pH-value (pH 5.5 and 7.0) were applied twice daily on the forehead and forearm of healthy volunteers in a randomized crossover trial. The skin surface pH was found to be significantly higher when the neutral preparation had been used, as was the propionibacterial count (p less than 0.05). The number of propionibacteria was significantly linked to the skin pH. Hence even minor differences in the pH of skin cleansing preparations seem to be of importance for the integrity of the skin surface. This should be taken into account when planning the formulation of optimal skin care products.

The failures of root canal preparation are due to some anatomical deviation (canal in "C" or "S") and some technique errors. The technique errors are usually present in canal root cleansing and shaping stage and are the result of endodontic treatment objectives deviation. Our study was made on technique errors while preparing the canal roots with hand ProTaper. Our study was made "in vitro" on 84 extracted teeth (molars, premolars, incisors and canines). The canal root of these teeth were cleansed and shaped with hand ProTaper by crown-down technique and canal irrigation with NaOCl(2,5%). The dental preparation control was made by X-ray. During canal root preparation some failures were observed like: canal root overinstrumentation, zipping and stripping phenomenon, discarded and/or fractured instruments. Hand ProTaper represents a revolutionary progress of endodontic treatment, but a deviation from accepted rules of canal root instrumentation can lead to failures of endodontic treatment.

Dirty liberals! Reminders of physical cleanliness influence moral and political attitudes.

PubMed

Helzer, Erik G; Pizarro, David A

2011-04-01

Many moral codes place a special emphasis on bodily purity, and manipulations that directly target bodily purity have been shown to influence a variety of moral judgments. Across two studies, we demonstrated that reminders of physical purity influence specific moral judgments regarding behaviors in the sexual domain as well as broad political attitudes. In Study 1, individuals in a public setting who were given a reminder of physical cleansing reported being more politically conservative than did individuals who were not given such a reminder. In Study 2, individuals reminded of physical cleansing in the laboratory demonstrated harsher moral judgments toward violations of sexual purity and were more likely to report being politically conservative than control participants. Together, these experiments provide further evidence of a deep link between physical purity and moral judgment, and they offer preliminary evidence that manipulations of physical purity can influence general (and putatively stable) political attitudes.

Deployment and testing of a second prototype expandable surgical chamber in microgravity

NASA Technical Reports Server (NTRS)

Markham, Sanford M.; Rock, John A.

1991-01-01

During microgravity exposure, two separate expandable surgical chambers were tested. Both chambers had been modified to fit the microgravity work station without extending over the sides of the table. Both chambers were attached to a portable laminar flow generator which served two purposes: to keep the chambers expanded during use; and to provide an operative area environment free of contamination. During the tests, the chambers were placed on various parts of a total body moulage to simulate management of several types of trauma. The tests consisted of cleansing contusions, debridement of burns, and suturing of lacerations. Also, indigo carmine dye was deliberately injected into the chamber during the tests to determine the ease of cleansing the chamber walls after contamination by escaping fluids. Upon completion of the tests, the expandable surgical chambers were deflated, folded, and placed in a flattened state back into their original containers for storage and later disposal. Results are briefly discussed.

The authors describe the use of three new antidepressants: Sertralilne, Paroxetine and Venlafaxine in treating Posttraumatic Stress Disorder and symptoms of Depression in adult Bosnian refugees victims of ethnic cleansing. 32 Bosnian refugees with PTSD and symptoms of Depression presenting for treatment of the mental health consequences of surviving ethnic cleansing, participated in a case series study. All subjects completed open trials of Sertraline (15), Paroxetine (12) or Venlafaxine (5), with standard clinical doses. Overall, Sertraline and Paroxetine yielded statistically significant improvement at 6 weeks in the total PTSD symptom severity, in each symptom cluster, in Beck Depression Inventory and in Global Assessment of Functioning. Venlafaxine produced statistically significant improvement at 6 weeks in the total PTSD symptom severity, in each symptom cluster and in Global Assessment of Functioning but did not yield significant improvement in symptoms of depression and had a high rate of side effects.

The efficacy of tea seed oil to clean foundation and eyeliner was evaluated. The safe and efficient tea seed oil makeup remover was developed. In vitro cleansing efficacy of makeup remover was UV-spectrophotometric validated. The stability evaluation by means of accelerated stability test was conducted. In vitro and in vivo cleansing efficacy of the removers was conducted in a comparison with benchmark majorly containing olive oil. Tea seed oil cleaned 90.64±4.56% of foundation and 87.62±8.35% of eyeliner. The stable with most appropriate textures base was incorporated with tea seed oil. Three tea seed oil removers (50, 55 and 60%) were stabled. The 60% tea seed oil remover significantly removed foundation better than others (94.48±3.37%; P<0.001) and the benchmark (92.32±1.33%), but insignificant removed eyeliner (87.50±5.15%; P=0.059). Tea seed oil remover caused none of skin irritation as examined in 20 human volunteers. A single-blind, randomized control exhibited that the tea seed oil remover gained a better preference over the benchmark (75.42±8.10 and 70.00±7.78%; P=0.974). The safe and efficient tea seed oil makeup removers had been developed. The consumers' choices towards the makeup remover containing the bio-oils are widen. In vitro cleansing efficacy during the course of makeup remover development using UV-spectrophotometric method feasible for pharmaceutic industries is encouraged.

Accurate electronic cleansing (EC) for CT colonography (CTC) enables the visualization of the entire colonic surface without residual materials. In this study, we evaluated the accuracy of a novel multi-material electronic cleansing (MUMA-EC) scheme for non-cathartic ultra-low-dose dual-energy CTC (DE-CTC). The MUMA-EC performs a wateriodine material decomposition of the DE-CTC images and calculates virtual monochromatic images at multiple energies, after which a random forest classifier is used to label the images into the regions of lumen air, soft tissue, fecal tagging, and two types of partial-volume boundaries based on image-based features. After the labeling, materials other than soft tissue are subtracted from the CTC images. For pilot evaluation, 384 volumes of interest (VOIs), which represented sources of subtraction artifacts observed in current EC schemes, were sampled from 32 ultra-low-dose DE-CTC scans. The voxels in the VOIs were labeled manually to serve as a reference standard. The metric for EC accuracy was the mean overlap ratio between the labels of the reference standard and the labels generated by the MUMA-EC, a dualenergy EC (DE-EC), and a single-energy EC (SE-EC) scheme. Statistically significant differences were observed between the performance of the MUMA/DE-EC and the SE-EC methods (p<0.001). Visual assessment confirmed that the MUMA-EC generated less subtraction artifacts than did DE-EC and SE-EC. Our MUMA-EC scheme yielded superior performance over conventional SE-EC scheme in identifying and minimizing subtraction artifacts on noncathartic ultra-low-dose DE-CTC images.

Single-dose lubiprostone along with split-dose PEG solution without dietary restrictions for bowel cleansing prior to colonoscopy: a randomized, double-blind, placebo-controlled trial.

Stengel, Joel Z; Jones, David P

2008-09-01

Proper colonic cleansing prior to colonoscopy is paramount to ensuring complete mucosal visualization and polyp identification. In a double-blind fashion, we compared single-dose lubiprostone (24 microg) versus placebo pretreatment prior to a split-dose polyethylene glycol electrolyte (PEG-E) bowel preparation without dietary restriction to determine the efficacy, safety, and patient tolerability. Two hundred patients referred for outpatient colorectal cancer screening were randomized to receive a single-dose of unlabeled lubiprostone (24 microg) or placebo prior to a split-dose PEG-E bowel preparation without dietary restriction. The patients were surveyed prior to the colonoscopy on the tolerability of the bowel preparation, and any adverse events were recorded. The cleanliness of the colon was graded by the endoscopist during the procedure utilizing the Ottawa bowel preparation scale. One hundred ninety-one patients completed the study (95%). Split-dose PEG-E with lubiprostone pretreatment was found to be more effective at bowel cleansing in each segment of the colon when compared with split-dose PEG-E with placebo (P < 0.001). Patients enrolled in the lubiprostone treatment arm rated the overall experience as more tolerable (P 0.003) and complained of less abdominal bloating (P 0.049). No differences were observed between the groups for treatment-emergent side effects or adverse events (P > 0.05). Single-dose lubiprostone prior to split-dose PEG-E without dietary restriction significantly improves colonic mucosa visualization during colonoscopy and is well tolerated by patients.

Development of efficacious anti-bacterial skin cleansing products has been limited by the availability of a pre-clinical (in vitro) method to predict clinical efficacy adequately. We report a simple and rapid method, designated as rapid agar plate assay (RAPA), that uses the bacteriological agar surface as a surrogate substrate for skin and combines elements of two widely used in vivo (clinical) methods (Agar Patch and Cup Scrub). To simulate the washing of the human hand or forearm skin with the test product, trypticase soy agar plates were directly washed with the test product and rinsed under running tap water. After air-drying the washed plates, test bacteria (Staphylococcus aureus or Escherichia coli) were applied and the plates were incubated at 37 degrees C for 18-24 h. Using S. aureus as the test organism, anti-bacterial bar soap containing triclocarbanilide showed a strong linear relationship (R(2) = 0.97) between bacterial dose and their per cent reduction. A similar dose-response relationship (R(2) = 0.96) was observed for anti-bacterial liquid hand soap against E. coli. RAPA was able to distinguish between anti-bacterial products based on the nature and level of actives in them. In limited comparative tests, results obtained by RAPA were comparable with the results obtained by clinical agar patch and clinical cup scrub methods. In conclusion, RAPA provides a simple, rugged and reproducible in vitro method for testing the relative efficacy of anti-bacterial skin cleansing products with a likelihood of comparable clinical efficacy. Further testing is warranted to improve the clinical predictability of this method.

The purpose of our study was to measure the dual-energy index (DEI) value of colonic luminal air in both phantom and clinical fecal-tagging dual-energy computed tomography (CT) colonography (DE-CTC) images and to demonstrate its impact on dual-energy electronic cleansing. For the phantom study, a custom-ordered colon phantom was scanned by a dual-energy CT scanner (SOMATON Definition Flash; Siemens Healthcare, Forchheim, Germany) at two photon energies: 80 and 140 kVp. Before imaging, the phantom was filled with a 300-mL mixture of simulated fecal materials tagged by a nonionic iodinated contrast agent at three contrast concentrations: 20, 40, and 60 mg/mL. Ten regions-of-interest (ROIs) were randomly placed in each of the colonic luminal air, abdominal fat, bony structure, and tagged material in each scan. For the clinical study, 22 DE-CTC (80 and 140 kVp) patient cases were collected, who underwent a low-fiber, low-residue diet bowel preparation and orally administered iodine-based fecal tagging. Twenty ROIs were randomly placed in each of the colonic luminal air, abdominal fat, abdominal soft tissue, and tagged fecal material in each scan. For each ROI, the mean CT values in both 80- and 140-kVp images were measured, and then its DEI was calculated. In the phantom study, the mean DEI values of luminal air were 0.270, 0.298, 0.386, and 0.402 for the four groups of tagging conditions: no tagged material and tagged with three groups of contrast concentrations at 20, 40, and 60 mg/mL. In the clinical study, the mean DEI values were 0.341, -0.012, -0.002, and 0.188 for colonic luminal air, abdominal fat, abdominal soft tissue, and tagged fecal material, respectively. In our study, we observed that the DEI values of colonic luminal air in DE-CTC images (>0.10) were substantially higher than the theoretical value of 0.0063. In addition, the observed DEI values of colonic luminal air were significantly higher than those of soft tissue. These findings have an important impact on electronic cleansing: it may provide an effective means of differentiating colonic soft-tissue structures from the air-tagging mixture caused by the partial volume effect and thus of minimizing the cleansing artifacts.

Achieving the best bowel preparation for colonoscopy

Bowel preparation is a core issue in colonoscopy, as it is closely related to the quality of the procedure. Patients often find that bowel preparation is the most unpleasant part of the examination. It is widely accepted that the quality of cleansing must be excellent to facilitate detecting neoplastic lesions. In spite of its importance and potential implications, until recently, bowel preparation has not been the subject of much study. The most commonly used agents are high-volume polyethylene glycol (PEG) electrolyte solution and sodium phosphate. There has been some confusion, even in published meta-analyses, regarding which of the two agents provides better cleansing. It is clear now that both PEG and sodium phosphate are effective when administered with proper timing. Consequently, the timing of administration is recognized as one of the central factors to the quality of cleansing. The bowel preparation agent should be administered, at least in part, a few hours in advance of the colonoscopy. Several low volume agents are available, and either new or modified schedules with PEG that usually improve tolerance. Certain adjuvants can also be used to reduce the volume of PEG, or to improve the efficacy of other agents. Other factors apart from the choice of agent can improve the quality of bowel cleansing. For instance, the effect of diet before colonoscopy has not been completely clarified, but an exclusively liquid diet is probably not required, and a low-fiber diet may be preferable because it improves patient satisfaction and the quality of the procedure. Some patients, such as diabetics and persons with heart or kidney disease, require modified procedures and certain precautions. Bowel preparation for pediatric patients is also reviewed here. In such cases, PEG remains the most commonly used agent. As detecting neoplasia is not the main objective with these patients, less intensive preparation may suffice. Special considerations must be made for patients with inflammatory bowel disease, including safety and diagnostic issues, so that the most adequate agent is chosen. Identifying neoplasia is one of the main objectives of colonoscopy with these patients, and the target lesions are often almost invisible with white light endoscopy. Therefore excellent quality preparation is required to find these lesions and to apply advanced methods such as chromoendoscopy. Bowel preparation for patients with lower gastrointestinal bleeding represents a challenge, and the strategies available are also reviewed here. PMID:25548470

Allograft tissue is a common graft choice for anterior cruciate ligament reconstruction (ACLR). Allograft sterilization methods vary widely across numerous commercial tissue vendors. Multiple studies, despite being limited in sample size, have suggested a higher rate of clinical failure associated with the use of allograft tissue in ACLR when compared with autograft. To examine the association of graft processing techniques, patient characteristics, and graft type with risk of revision surgery after allograft ACLR. Cohort study; Level of evidence, 3. A retrospective cohort study was conducted that used an integrated United States health care system's ACLR registry to identify primary unilateral cases in which allografts were used. Aseptic revision was the endpoint of the study. Allograft type, processing methods (irradiation dose, AlloWash, AlloTrue, BioCleanse), and graft donor age were assessed as potential risk factors for revision, with adjustment for patient age, sex, and body mass index (BMI) by use of survival analysis. Hazard ratios (HR) and 95% confidence intervals (CIs) were calculated. A total of 5968 primary ACLR cases with allograft were included in the study, of which 3688 (61.8%) were male patients. The median age of the cohort at the time of surgery was 34.1 years (interquartile range, 24.1-42.9 years). The mean time to follow-up (±SD) was 2.1 ± 1.5 years. There were 3751 (62.9%) allograft ACLRs using soft tissue, 1188 (19.9%) with Achilles tendon, and 1029 (17.2%) with bone-patellar tendon-bone (BPTB). Graft processing groups included BioCleanse (n = 367), AlloTrue or AlloWash (n = 2278), irradiation greater than 1.8 Mrad (n = 1146), irradiation up to 1.8 Mrad (n = 3637), and no irradiation (n = 1185). There were 156 (2.6%) aseptic revisions. After adjustment for patient age, sex, and BMI, the use of BioCleanse (HR = 2.45; 95% CI, 1.36-4.40) and irradiation greater than 1.8 Mrad (HR = 1.64; 95% CI, 1.08-2.49) were associated with a higher risk of revision when compared with all other methods of processing. BPTB allografts were at higher risk of revision (HR = 1.79; 95% CI, 1.20-2.66) when compared with soft tissue allografts. Conversely, with every 5-year increase in age, the risk of revision was 0.67 (95% CI, 0.61-0.73) times lower. Male patients were found to be at higher risk of revision when compared with females (HR = 1.47; 95% CI, 1.04-2.07). The use of AlloWash or AlloTrue processing, patient BMI, and graft donor age did not affect revision rate significantly. In the largest known study of its kind examining outcome after primary allograft ACLR, graft irradiation greater than 1.8 Mrad, BioCleanse graft processing, younger patient age, male patients, and BPTB allograft were all associated with a higher risk of clinical failure and subsequent revision surgery. © 2015 The Author(s).

Clay liquid detergents (CLDs) were developed for cleansing religiously-prohibited dirt ('najis') according to Islamic law. Four types of clay were selected: marl, kaolin, bentonite and veegum. After product development trials, five CLD formulations with varying combinations of clays were qualified for stability testing. Three exaggerated temperature conditions were considered: 4 degrees C for 24 h, 50 degrees C for 7 days, and 40 degrees C for 1 month. The CLDs were also evaluated at 30, 60 and 90 days after production, while being stored at room temperature (RT30, RT60 and RT90). Physical and chemical characteristics including pH, colour, viscosity, surface tension, foam tests and sensory liking scores were evaluated. Our results showed that the kaolin-based formula, F2, had an optimal pH (closest to skin pH) of 5.08. The other formulas ranged from pH 6 to 8. Colour shades of the CLDs ranged from white, to creamy white, to mildly greenish-white. The foaming properties of the CLDs, the means +/- SD of foam heights at 0 and 5 min, using the Ross-Miles test, were 19.13 +/- 0.25 to 20.88 +/- 0.45 cm at RT90 and were comparable with those of commercial detergents. Foam stability of all CLDs was high, as shown from the foam heights between 0 and 5 min being not significantly different (P > 0.05). The surface tensions, means +/- SD, of CLD solutions were between 27.94 +/- 0.08 and 28.72 +/- 0.04 mN m(-1), which were slightly better than the surface tension of 29.08 +/- 0.04 mN m(-1) for sodium lauryl sulphate. There was a weak negative relationship between surface activity and foam height, based on the pooled data of the CLDs (R(2) = 0.209, P < 0.01). The viscosity of four CLDs ranged from 16 317 to 49 036 mPa s. In conclusion, CLDs can be formulated with good stability. F2 (kaolin-based, with a white, creamy texture) was the best CLD formula. It had the highest surface activity, moderate lathering and pleasant physical appearance.

Low-volume plus ascorbic acid vs high-volume plus simethicone bowel preparation before colonoscopy

AIM: To investigate the effectiveness of low-volume plus ascorbic acid [polyethylene glycol plus ascorbic acid (PEG + Asc)] and high-volume plus simethicone [polyethylene glycol plus simethicone (PEG + Sim)] bowel preparations. METHODS: A total of one hundred and forty-four outpatients (76 males), aged from 20 to 84 years (median age 59.5 years), who attended our Department, were divided into two groups, age and sex matched, and underwent colonoscopy. Two questionnaires, one for patients reporting acceptability and the other for endoscopists evaluating bowel cleansing effectiveness according to validated scales, were completed. Indications, timing of examination and endoscopical findings were recorded. Biopsy forceps were used as a measuring tool in order to determine polyp endoscopic size estimation. Difficulty in completing the preparation was rated in a 5-point Likert scale (1 = easy to 5 = unable). Adverse experiences (fullness, cramps, nausea, vomiting, abdominal pain, headache and insomnia), number of evacuations and types of activities performed during preparation (walking or resting in bed) were also investigated. RESULTS: Seventy-two patients were selected for each group. The two groups were age and sex matched as well as being comparable in terms of medical history and drug therapies taken. Fourteen patients dropped out from the trial because they did not complete the preparation procedure. Ratings of global bowel cleansing examinations were considered to be adequate in 91% of PEG + Asc and 88% of PEG + Sim patients. Residual Stool Score indicated similar levels of amount and consistency of residual stool; there was a significant difference in the percentage of bowel wall visualization in favour of PEG + Sim patients. In the PEG + Sim group, 12 adenomas ≤ 10 mm diameter (5/left colon + 7/right colon) vs 9 (8/left colon + 1/right colon) in the PEG + Asc group were diagnosed. Visualization of small lesions seems to be one of the primary advantages of the PEG + Sim preparation. CONCLUSION: PEG + Asc is a good alternative solution as a bowel preparation but more improvements are necessary in order to achieve the target of a perfect preparation. PMID:22180711

Seventy-two patients were selected for each group. The two groups were age and sex matched as well as being comparable in terms of medical history and drug therapies taken. Fourteen patients dropped out from the trial because they did not complete the preparation procedure. Ratings of global bowel cleansing examinations were considered to be adequate in 91% of PEG + Asc and 88% of PEG + Sim patients. Residual Stool Score indicated similar levels of amount and consistency of residual stool; there was a significant difference in the percentage of bowel wall visualization in favour of PEG + Sim patients. In the PEG + Sim group, 12 adenomas ≤ 10 mm diameter (5/left colon + 7/right colon) vs 9 (8/left colon + 1/right colon) in the PEG + Asc group were diagnosed. Visualization of small lesions seems to be one of the primary advantages of the PEG + Sim preparation. PEG + Asc is a good alternative solution as a bowel preparation but more improvements are necessary in order to achieve the target of a perfect preparation.

Acute sore throat (pharyngitis) is one of the most common illnesses for which children are seen by primary care physicians. Most cases are caused by viruses and are benign and self-limiting. Clinically proven, over-the-counter throat lozenges provide rapid and effective relief of acute sore throat symptoms, and are increasingly important in self-management of this condition. The purpose of this study (International Standard Randomized Controlled Trial Number: ISRCTN34958871) was to evaluate the acceptability of two licensed, commercially available sore throat lozenges containing amylmetacresol and 2,4-dichlorobenzyl (AMC/DCBA)--one strawberry flavored and the other orange flavored--in healthy children. This was an open-label, single-dose, crossover, taste-testing study in children recruited via a clinical database and advertisements over a 3.5-week period. Potentially eligible participants were invited to attend the taste-testing session at a clinic. At the screening session, which took place either before or on the day of taste testing, details of relevant medical history, medication, and demographics were recorded. Of the 108 screened subjects, 102 were recruited. These were healthy male and female children aged 6-12 years. Each child cleansed their palate with water and water biscuits before tasting a strawberry-flavored lozenge (Strepsils® strawberry sugar free, Reckitt Benckiser Healthcare Limited, Nottingham, UK; PL 00063/0395), which was sucked for 1 minute and then expelled. The orange-flavored lozenge (Strepsils® orange with vitamin C, Reckitt Benckiser Healthcare Limited, Nottingham, UK; PL 016242152) was tasted at least 15 minutes later following further cleansing of the palate. The spontaneous reaction of the child on tasting each lozenge was observed and recorded. Subjects were asked to indicate their liking for each lozenge, using a 7-point hedonic facial scale, and were required to answer a series of questions relating to what they liked and disliked about the taste and the feel of the lozenge in the mouth and throat. The primary endpoint was the proportion of subjects with a hedonic facial score of >4. Secondary endpoints included the spontaneous reaction of the child on tasting the lozenge and responses to questions related to taste. The taste of the lozenge was scored >4 (i.e. 'good', 'really good', or 'super good') by 85.3% of subjects for the strawberry flavor and 49.0% for the orange flavor (p < 0.0001). The mean (standard deviation) score was 5.72 (1) for the strawberry-flavored lozenge and 4.35 (2) for the orange-flavored lozenge. The proportion of subjects willing to take the lozenge again was 94% for the strawberry flavor and 56% for the orange flavor. Strawberry-flavored AMC/DCBA lozenges were liked by, and acceptable to, the majority of the children. AMC/DCBA orange-flavored lozenges were also liked by, and acceptable to, approximately half the children. Overall, both strawberry and orange would be suitable flavors for lozenges intended for children when they suffer from sore throat.

Prolonged Effect of Severe Wildfires on Mercury and Other Volatiles in Forest Soils of the Lake Superior Region, USA

NASA Astrophysics Data System (ADS)

Cannon, W. F.; Woodruff, L. G.

2003-12-01

Soils in Isle Royale National Park, Michigan and Voyageurs National Park, Minnesota show spatial patterns of depletion of total Hg, organic C, Se, total S, P, and Pb within areas of severe, stand-replacing wildfires that burned in 1936, approximately 65 years prior to our current study. The fires burned during a regional drought, were of high severity, and likely consumed a high percentage of organic forest-floor material (O-horizon). A "fire factor" is defined by positive correlations among Hg, C, Se, S, P, and Pb. A factor score for this six-element grouping derived from factor analysis was assigned to each sample. The scores show a high spatial correlation with the footprint of the 1936 fires in both parks, particularly for A-horizon soils. Because many of these elements are volatile, and are highly correlated with soil organic matter, observed depletions likely represent instantaneous atmospheric release during combustion of O-horizon soils coupled with decades-long reduction of organic matter on the forest floor and near-surface soils. Nearly complete combustion of the modern O-horizon would release roughly 1 mg Hg/m2 from the forest floor. Decades-long disturbance resulting from destruction of mature forests and gradual regrowth following fire also play an important role in Hg cycling. Destruction of a mature forest results in decreased deposition of Hg from litterfall as well as throughfall, which contributes Hg by wash-off of dry deposited Hg from foliar surfaces. Hg in forest soils may follow a fire-dependent cycle in which sudden Hg loss during fire is followed by a period of continued Hg loss as evasion exceeds sequestration in the early stand-replacement stage, finally to resume gradual buildup in later stages of forest regrowth. In the Lake Superior region this cycle exceeds 65 years in duration and is of the same magnitude as the fire return interval for this region. Forests that are controlled by fire-induced cycles of stand replacement may also be in continuous cycles of Hg sequestration and emission. Fire history appears to be a major determinant in the amount of Hg stored in forest soils. Fire almost certainly releases Hg to the atmosphere as forest floor material is burned and thus contributes to atmospheric Hg loads. Fire also appears to cleanse burned areas of Hg both by the atmospheric release during combustion and longer-term release during post-fire forest reorganization. Fire cleansing appears to persist for decades after severe fires and may ameliorate Hg contamination of aquatic food webs by decreasing the soil Hg load of burned watersheds.

Deep multi-spectral ensemble learning for electronic cleansing in dual-energy CT colonography

NASA Astrophysics Data System (ADS)

2017-03-01

We developed a novel electronic cleansing (EC) method for dual-energy CT colonography (DE-CTC) based on an ensemble deep convolution neural network (DCNN) and multi-spectral multi-slice image patches. In the method, an ensemble DCNN is used to classify each voxel of a DE-CTC image volume into five classes: luminal air, soft tissue, tagged fecal materials, and partial-volume boundaries between air and tagging and those between soft tissue and tagging. Each DCNN acts as a voxel classifier, where an input image patch centered at the voxel is generated as input to the DCNNs. An image patch has three channels that are mapped from a region-of-interest containing the image plane of the voxel and the two adjacent image planes. Six different types of spectral input image datasets were derived using two dual-energy CT images, two virtual monochromatic images, and two material images. An ensemble DCNN was constructed by use of a meta-classifier that combines the output of multiple DCNNs, each of which was trained with a different type of multi-spectral image patches. The electronically cleansed CTC images were calculated by removal of regions classified as other than soft tissue, followed by a colon surface reconstruction. For pilot evaluation, 359 volumes of interest (VOIs) representing sources of subtraction artifacts observed in current EC schemes were sampled from 30 clinical CTC cases. Preliminary results showed that the ensemble DCNN can yield high accuracy in labeling of the VOIs, indicating that deep learning of multi-spectral EC with multi-slice imaging could accurately remove residual fecal materials from CTC images without generating major EC artifacts.

Whole body cleaning agent containing N-acyltaurate

NASA Technical Reports Server (NTRS)

Lentsch, Steven E. (Inventor)

1992-01-01

The subject invention relates to a human cleansing agent particularly suitable for use in long duration spaceflight and to a method of bathing with the agent. The agent of the subject invention is in the form of a paste having a pH of 5.0 to 7.9 which comprises an acyltaurate, a skin conditioner, a hair conditioner, and a preservative. More specifically, it includes sodium N-coconut acid-N-methyl taurate, in combination with soybean lecithin, polyquaternium 16, and formalin. This particular combination satisfies the following objectives: (1) that it be usable with a minimum amount of water per shower (approximately 1 gallon); (2) that it be easily separated from the water for purposes of water reclamation; (3) that it be pH compatible with skin and hair; (4) that it rinse well in deionized water; (5) that it be mild to skin and eyes; (6) that it effectively clean both skin and hair; (7) that it be suitable for use in zero gravity; and (8) that it provide ease of combing of wet and dry hair. The method of the invention includes the steps of wetting the skin and hair with a small quantity of water, lathering the skin with the paste, rinsing the lather from the skin and hair with a small quantity of water to produce a rinse water containing the cleansing agent, defoaming the rinse water, and supplying the defoamed rinse water to a water reclamation unit for recycling the water. The novelty of the invention appears to lie in the particular formulation of the cleansing agent and its method of use which provide optimal results under the given constraints and objectives.

Constipation is a common complaint, frequently treated with cleansing enema. Enemas can be very effective but may cause serious adverse events, such as perforation or metabolic derangement. Our aim was to evaluate the outcome of the use of cleansing enema for acute constipation and to assess adverse events within 30 days of therapy. We performed a two-phase study: an initial retrospective and descriptive study in 2010, followed by a prospective study after intervention, in 2011. According to the results of the first phase we established guidelines for the treatment of constipation in the Emergency Department and then used these in the second phase. There were 269 and 286 cases of severe constipation in the first and second periods of the study, respectively. In the first study period, only Fleet® Enema was used, and in the second, this was changed to Easy Go enema (free of sodium phosphate). There was a 19.2% decrease in the total use of enema, in the second period of the study (P < 0.0001). Adverse events and especially, the perforation rate and the 30-day mortality in patients with constipation decreased significantly in the second phase: 3 (1.4%) versus 0 (P = 0.0001) and 8 (3.9%) versus 2 (0.7%) (P = 0.0001), for perforation and death in the first and second period of the study, respectively. Enema for the treatment of acute constipation is not without adverse events, especially in the elderly, and should be applied carefully. Perforation, hyperphosphatemia (after Fleet Enema), and sepsis may cause death in up to 4% of cases. Guidelines for the treatment of acute constipation and for enema administration are urgently needed.

Background. The aim of the present study was to evaluate the effect of Corega and 2.5% sodium hypochlorite cleansing agents on the shear and tensile bond strengths of GC soft liner to denture base. Methods. A total of 144 samples (72 samples for tensile and 72 for shear bond strength evaluations) were prepared. The samples in each group were subdivided into three subgroups in terms of the cleansing agent used (2.5% sodium hypochlorite, Corega and distilled water [control group]). All the samples were stored in distilled water, during which each sample was immersed for 15 minutes daily in sodium hypochlorite or Corega solutions. After 20 days the tensile and shear bond strengths were determined using a universal testing machine. In addition, a stereomicroscope was used to evaluate fracture modes. Data were analyzed with one-way ANOVA, using SPSS 16. Results. The results of post hoc Tukey tests showed significant differences in the mean tensile and shear bond strength values between the sodium hypochlorite group with Corega and control groups (P=0.001 for comparison of tensile bond strengths between the sodium hypochlorite and control groups, and P<0.001 for the comparison of tensile bond strengths between the sodium hypochlorite and Corega groups and the shear bond strengths between the sodium hypochlorite and Corega groups, and sodium hypochlorite and control groups).The majority of failures were cohesive in the control and Corega groups and cohesive/adhesive in the sodium hypochlorite group. Conclusion. Immersion of soft liners in Corega will result in longevity of soft liners compared to immersion in sodium hypochlorite solution and sodium hypochlorite solution significantly decreased the tensile and shear bond strengths compared to the control and Corega groups.

To assess visual outcomes of retreatment after laser in situ keratomileusis (LASIK) by lifting the flap or performing photorefractive keratectomy (PRK) on the flap, as well as to establish whether there was an increased risk of epithelial ingrowth (EIG) when LASIK and lifting of the flap are separated by a long time interval and to determine the incidence of corneal haze after PRK. Retrospective study of 4077 patients (5468 eyes) who underwent LASIK and subsequent retreatment were reviewed in order to study their visual results and identify cases of EIG and corneal haze. Enhancements included 5196 eyes from 3876 patients that were retreated by lifting the flap, and 272 eyes from 201 patients that were retreated by PRK on the flap. No statistically significant differences were found between the retreatments in terms of predictability, efficacy, and safety. A total of 704 cases of EIG were found after lifting the flap, for which surgical cleansing was necessary in 70. Surgical cleansing decreased the efficacy index when compared with patients with EIG who did not need cleansing (P=.01). Differences in terms of safety and predictability were not statistically significant. The incidence of corneal haze after ablation of the surface of the previous flap was 14.34%, although none of these cases were clinically relevant. Visual outcomes were similar between patients who were retreated by lifting the flap and those who underwent PRK. The incidence of EIG when the flap was lifted was 13.55%. The incidence of EIG increases with the time elapsed between the primary procedure and retreatment. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

Faecal serine proteases (FSPs) may play a role in irritable bowel syndrome with diarrhoea (IBS-D), but their origin is unclear. We aimed to structurally characterise them and define the impact of colonic cleansing and transit time. Faecal samples were obtained from 30 healthy volunteers (HV) and 79 patients with IBS-D participating in a trial of ondansetron versus placebo. Colonic transit was measured using radio-opaque markers. Samples were also obtained from 24 HV before and after colonic cleansing with the osmotic laxative MoviPrep. FSPs were purified from faecal extracts using benzamidine-Sepharose affinity chromatography. SDS-PAGE profiled components were identified using trypsinolysis and tandem mass spectrometry. Functional protease activity in faecal extracts was measured using a colorimetric assay based on the proteolysis of azo-casein. Protein analysis identified the most abundant FSPs as being of human origin and probably derived from pancreatic juice. Functional assays showed increased faecal protease (FP) and amylase in patients with IBS-D compared with HV. Those with higher amylase had significantly higher FP and greater anxiety. FP activity correlated negatively with whole gut transit in patients with IBS-D (Spearman r=-0.32, p=0.005) and HV (r=-0.55, p=0.014). Colon cleansing caused a significant rise in FP activity in HV from a baseline of median (IQR) 253 (140-426) to 1031 (435-2296), levels similar to those seen in patients with IBS-D. FSP activity correlated positively with days/week with urgency. The most abundant FSPs are of human origin. Rapid transit through the colon and/or decreased (possibly bacterial) proteolytic degradation increases their faecal concentration and could contribute to visceral hypersensitivity in patients with IBS-D.

Background: Studies have shown that Integrated Yoga reduces pain, disability, anxiety and depression and increases spinal flexibility and quality-of-life in chronic low back pain (CLBP) patients. Objective: The objective of this study was to compare the effect of two yoga practices namely laghu shankha prakshalana (LSP) kriya, a yogic colon cleansing technique and back pain specific asanas (Back pain special technique [BST]) on pain, disability, spinal flexibility and state anxiety in patients with CLBP. Materials and Methods: In this randomized control (self as control) study, 40 in-patients (25 were males, 15 were females) between 25 and 70 years (44.05 ± 13.27) with CLBP were randomly assigned to receive LSP or BST sessions. The measurements were taken immediately before and after each session of either of the practices (30 min) in the same participant. Randomization was used to decide the day of the session (3rd or 5th day after admission) to ensure random distribution of the hang over effect of the two practices. Statistical analysis was performed using the repeated measures analysis of variance. Results: Significant group * time interaction (P < 0.001) was observed in 11 point numerical rating scale, spinal flexibility (on Leighton type Goniometer) and (straight leg raise test in both legs), Oswestry Disability Index, State Anxiety (XI component of Spieldberger's state and trait anxiety inventory. There was significantly (P < 0.001, between groups) better reduction in LSP than BST group on all variables. No adverse effects were reported by any participant. Conclusion: Clearing the bowel by yoga based colon cleansing technique (LSP) is safe and offers immediate analgesic effect with reduced disability, anxiety and improved spinal flexibility in patients with CLBP.

Bacterial skin infections: management of common streptococcal and stapylococcal lesions.

PubMed

Witkowski, J A; Parish, L C

1982-10-01

Skin infection occurs in any age-group, sex, and race but is particularly common in children. It is usually minor, but may indicate underlying systemic disease or may lead to systemic infection. Streptococci and staphylococci are common causes. Group A beta-hemolytic streptococci account for the majority of streptococcal infections in man. Infection most often involves the lower extremities and produces spreading erythema and necrosis but little purulence. Staphylococcal infections most commonly involve the face, the hair follicles and eccrine sweat ducts being the initial sites. Lesions appear as bullae and pustules with a narrow rim of erythema. Intense cellulitis surrounding the lesions usually points to a virulent, penicillin-resistant strain of Staphylococcus. Treatment of both types of infection consists of cleansing with antibacterial agents, removal of crusts, application of warm compresses, and use of topical or systemic antibiotics, depending on the severity of the infection and the type of pyoderma involved.

Context: Plaque control has been shown to be pivotal in maintaining the optimal periodontal health. Mechanical plaque control is the most popular option for establishing the optimal oral health. Toothbrushes have been the novel tool for mechanical cleansing. However, the abrasive potential of the toothbrushes on the enamel surface is an area in gray. Aims: The aim of this in vitro study is to evaluate the abrasivity of the toothbrush versus the velcro fasteners. Materials and Methods: The mounted teeth of both the groups were subjected to abrasion test, and the tooth surfaces were observed for the possible abrasions from the oscillating strokes (toothbrush) and frictional contacts (hook and loop velcro) and examined under the scanning electron microscope. Results: Comparative assessment of both velcro (hook and loop) and toothbrush bristles did not reveal any evidence of abrasion on the tooth specimens. Conclusions: Veclro fasteners are safe and qualitatively at par to the manual toothbrush for their efficacy and efficiency in teeth cleansing PMID:26229264

Washing the guilt away: effects of personal versus vicarious cleansing on guilty feelings and prosocial behavior

2014-01-01

For centuries people have washed away their guilt by washing their hands. Do people need to wash their own hands, or is it enough to watch other people wash their hands? To induce guilt, we had participants write about a past wrong they had committed. Next, they washed their hands, watched a washing-hands video, or watched a typing-hands video. After the study was over, participants could help a Ph.D. student complete her dissertation by taking some questionnaires home and returning them within 3 weeks. Results showed that guilt and helping behavior were lowest among participants who washed their hands, followed by participants who watched a washing-hands video, followed by participants who watched a typing-hands video. Guilt mediated the effects of cleansing on helping. These findings suggest that washing one’s own hands, or even watching someone else wash their hands, can wash away one’s guilt and lead to less helpful behavior. PMID:24616686

The failures of root canal preparation are due to some anatomical deviation (canal in “C” or “S”) and some technique errors. The technique errors are usually present in canal root cleansing and shaping stage and are the result of endodontic treatment objectives deviation. Objectives: Our study was made on technique errors while preparing the canal roots with hand ProTaper. Methodology: Our study was made “in vitro” on 84 extracted teeth (molars, premolars, incisors and canines). The canal root of these teeth were cleansed and shaped with hand ProTaper by crown-down technique and canal irrigation with NaOCl(2,5%). The dental preparation control was made by X-ray. Results: During canal root preparation some failures were observed like: canal root overinstrumentation, zipping and stripping phenomenon, discarded and/or fractured instruments. Conclusions: Hand ProTaper represents a revolutionary progress of endodontic treatment, but a deviation from accepted rules of canal root instrumentation can lead to failures of endodontic treatment.

The Buildings Performance Database (BPD) includes empirically measured data from a variety of data sources with varying degrees of data quality and data availability. The purpose of the data preparation process is to maintain data quality within the database and to ensure that all database entries have sufficient data for meaningful analysis and for the database API. Data preparation is a systematic process of mapping data into the Building Energy Data Exchange Specification (BEDES), cleansing data using a set of criteria and rules of thumb, and deriving values such as energy totals and dominant asset types. The data preparation processmore » takes the most amount of effort and time therefore most of the cleansing process has been automated. The process also needs to adapt as more data is contributed to the BPD and as building technologies over time. The data preparation process is an essential step between data contributed by providers and data published to the public in the BPD.« less

As part of the feasibility study for the Microbicides Development Programme Phase 3 trial of a vaginal microbicide in Mwanza, a variety of quantitative and qualitative methods were used to describe these practices, associations with behaviour and underlying social norms among women working in food and recreational facilities. Intravaginal cleansing by inserting fingers and either water alone or soap and water was thought necessary to remove “uchafu” (dirt), referring to vaginal secretions, including menstrual blood and post-coital discharge. Vaginal cleansing was carried out within 2 hours after 45% of sex acts. Sexual enhancement practices were less common. Intravaginal and menstrual practices and associated behaviours and demographic factors should be measured and monitored throughout microbicide trials to enable analyses of their impacts on microbicide effectiveness.

The aim of this study was to investigate the prevalence of Demodex spp. in the eyelash follicles obtained from patients seen in our ophthalmology clinic, to define the symptoms of this infestation, and to examine the effectivity of the therapy. This study was conducted in Department of Ophthalmology and Parasitology, Dokuz Eylül University, School of Medicine. Our study included 82 cases that were seen in the Ophthalmology Department and Parasitology Department for various reasons. We have also observed that the presence of Demodex spp. provokes itching and redness in the eyes and that using baby shampoo for cleansing the face reduces the risk of infestation. After the treatment of 32 cases with 4% pilocarpin HCl gel, we achieved a total cure in 12 eyes (37.5%), partial improvement in 13 eyes (40.6%), (making a total of 25 eyes, 78.1%). The treatment was unsuccessful in 7 eyes (21.9%). In patients with Demodex spp. cleansing with baby shampoo and treating by pilocarpin gel may be used in treatment.

Role of female intimate hygiene in vulvovaginal health: Global hygiene practices and product usage.

2017-12-01

Women use various feminine hygiene products, often as part of their daily cleansing routine; however, there is a paucity of published medical literature related to the external vulva and how personal hygiene practices can affect it. This review article provides background information on the physiological changes that occur during women's lives and reviews the relevance of transient and resident microbiota as they relate to common vaginal and vulvar disorders. It also discusses the need for female intimate hygiene, common practices of feminine hygiene from a global perspective, and the potential benefits of using suitable external, topical feminine vulvar washes to minimize the risk of vulvovaginal disorders and to improve overall intimate health in women around the world. Supported by international guidelines, daily gentle cleansing of the vulva is an important aspect of feminine hygiene and overall intimate health. Women should be encouraged to choose a carefully formulated and clinically tested external wash that provides targeted antimicrobial and other health benefits without negatively impacting on the natural vulvovaginal microbiota.

Wash water waste pretreatment system

1977-01-01

Investigations were completed on wash waters based on each candidate personal cleansing agent. Evaluations of coagulants, antifoam agents, and the effect of promising antifoams on the chemical precipitation were included. Based on these evaluations two candidate soaps as well as their companion antifoam agents were selected for further work. Operating parameters included the effect of soap concentration, ferric chloride concentration, duration of mixing, and pore size of depth filters on the degree of soap removal. The effect of pressure on water flow through filter cartridges and on the rate of decline of water flow was also investigated. The culmination of the program was the recommendation of a pretreatment concept based on chemical precipitation followed by pressure filtration.

Wound healing in orthopaedic care is affected by the causes of the wound, as well as concomitant therapies used to repair musculoskeletal structures. Promoting the health of the host and creating an environment to foster natural healing processes is essential for helping to restore skin integrity. Normal wound healing physiologic processes, factors affecting wound healing, wound classification systems, unique characteristics of orthopaedic wounds, wound contamination and drainage characteristics, and potential complications are important to understand in anticipation of patient needs. Accurate wound assessment and knowledge of nursing implications with specific wound care measures (cleansing, debridement, and dressings) is important for quality care. New technologies are enhancing traditional wound care measures with goals of effective comfortable wound care to promote restoration of skin integrity.

Introduction: Alveolar osteitis (AO) is a complication of tooth extraction which indicates inflammation of alveolar bone of either maxilla or mandible. This study uses Apitherapy where honey catalyses biological reactions to improve immune system, makes local environment unbearable for microorganisms in the affected socket and enhances healing. Materials and Methods: 50 patients of AO were included in the study. After cleansing of the affected socket, honey dressing was applied. Dressings were changed daily for first 2 days and then altenatively. In biochemical investigations, CRP levels in the body were measured using Nephelometry method. Microbiological examination was done for the identification of microorganism and semi quantitative count of colony forming units. Result: Results were assessed from clinical, microbiological, biochemical and radiological findings at 1st, 2nd, 3rd, 5th, 7th day based on VAS score, erythema, pus discharge, swelling, lymphadenitis, fever, bleeding on probing, exposed bone and necrotic debris. Pre-Treatment CRP was 2.08 ± 1.62 which significantly (P = 0.0001) decreased to 0.82 ± 0.48. Mean change and average percentage change were 1.25 ± 1.51 and 44.1% respectively. Conclusion: Majority of the patients with exposed bone got healed socket with evidance of granulation tissue and healing gingiva in about one week. CRP levels at the completion of treatment of AO with honey dressing showed a significant decrease from the pre-treatment values indicating fast recovery. Microbiological examination showed presence of normal commensal flora at AO sites like Streptococcus, Staphyloccocus and Enterococcus. So, the role of bacteria in the genesis of AO, if any, appears unclear. PMID:28356684

Cleaner Air for Home and Office

NASA Technical Reports Server (NTRS)

1989-01-01

Increased insulation has led to higher concentrations in homes and offices of toxic chemicals caused by emissions from synthetic building components. Recent NASA research regarding future interplanetary manned spacecraft has shown that certain plants can absorb gasses, reducing indoor air pollution. After working with water purifying water hyacinths, Dr. B. C. Wolverton at NSTL developed a carbon/plant filter system to remove chemicals, smoke, etc. Two companies have commercialized the system. Bio-safe provides plants, a bed of activated carbon and an air pump installed near the plant's roots. Pollutants are trapped by the charcoal and either digested by the roots or broken down by microorganisms. Purified air is then directed back into the room. Applied Indoor Resource Company markets Bio-Pure, which includes plants on a layer of patented soil medium with activated carbon. Legumes and mosses filter the air; a blower moves air through the filtering system for cleansing by microorganisms. Research at NSTL continues, and the system may eventually be enlarged.

2017-05-01

Seven halogenated volatile organic compounds (HVOCs) and two haloacetic acids were detected and quantified in 15 household products, including sodium hypochlorite, by gas chromatography-mass spectrometry (GC-MS). Chloroform was detected in a range of 0.2-30.2 mg kg -1 in all products, and carbon tetrachloride was observed in 13 samples in a range of 0.05-352 mg kg -1 . Dichloroacetic acid and trichloroacetic acid were also detected up to 94 and 146 mg kg -1 in household products. The estimated human exposures of chloroform, carbon tetrachloride, dichloroacetic acid and trichloroacetic acid were calculated to 0.041, 0.240, 0.913 and 2.39 mg/kg/day by the exposure algorithm from the Japan National Institute of Technology and Evaluation, respectively. According to the calculated result, the total estimated human exposure of chloroform were determined to exceed the tolerable concentration of inhalation exposure presented by the World Health Organization. The DBPs should be controlled to the lowest concentrations in the chlorine-containing household cleansing products. Copyright © 2017 Elsevier Ltd. All rights reserved.

Combination could be another tool for bowel preparation?

PubMed Central

Soh, Jae Seung; Kim, Kyung-Jo

2016-01-01

Optimal bowel preparation increases the cecal intubation rate and detection of neoplastic lesions while decreasing the procedural time and procedural-related complications. Although high-volume polyethylene glycol (PEG) solution is the most frequently used preparation for bowel cleansing, patients are often unwilling to take PEG solution due to its large volume, poor palatability, and high incidence of adverse events, such as abdominal bloating and nausea. Other purgatives include osmotic agents (e.g., sodium phosphate, magnesium citrate, and sodium sulfate), stimulant agents (e.g., senna, bisacodyl, and sodium picosulfate), and prokinetic agents (e.g., cisapride, mosapride, and itopride). A combination of PEG with an osmotic, stimulant, or prokinetic agent could effectively reduce the PEG solution volume and increase patients’ adherence. Some such solutions have been found in several published studies to not be inferior to PEG alone in terms of bowel cleansing quality. Although combination methods showed similar efficacy and safety, the value of these studies is limited by shortcomings in study design. New effective and well-tolerated combination preparations are required, in addition to rigorous new validated studies. PMID:26973388

Contamination of blood cultures during venepuncture: fact or myth?

PubMed Central

Shahar, E.; Wohl-Gottesman, B. S.; Shenkman, L.

1990-01-01

Contamination of blood cultures is believed to occur mainly during the venepuncture procedure. Consequently, meticulous preparation of the venepuncture site is widely recommended. To determine whether the contamination rate is indeed affected by the quality of the antiseptic procedure at the venepuncture site, 181 paired cultures were collected from 176 patients during a 6-month period after either strict antiseptic cleansing of skin with alcohol followed by povidone-iodine, or after brief disinfection with alcohol alone. The contamination rate was not influenced by the antiseptic procedure, and corresponded to the accepted percentage reported in most other studies. Eight false positive cultures (4.4%) were obtained after strict antisepsis of the skin and 6 (3.3%) after short simple cleansing with alcohol (P = 0.39). Our results suggest that contamination of blood cultures may not be related to the venepuncture procedure--regardless of the antiseptic technique used--but may be due to later stages of laboratory handling and processing of the specimens. Review of the literature has provided further indirect evidence to support this conclusion. PMID:2084653

2016-12-01

Instructional videos on bowel preparation have been shown to improve bowel preparation scores during colonoscopy. YouTube™ is one of the most frequently visited website on the internet and contains videos on bowel preparation. In an era where patients are increasingly turning to social media for guidance on their health, the content of these videos merits further investigation. We assessed the content of bowel preparation videos available on YouTube™ to determine the proportion of YouTube™ videos on bowel preparation that are high-content videos and the characteristics of these videos. YouTube™ videos were assessed for the following content: (1) definition of bowel preparation, (2) importance of bowel preparation, (3) instructions on home medications, (4) name of bowel cleansing agent (BCA), (5) instructions on when to start taking BCA, (6) instructions on volume and frequency of BCA intake, (7) diet instructions, (8) instructions on fluid intake, (9) adverse events associated with BCA, and (10) rectal effluent. Each content parameter was given 1 point for a total of 10 points. Videos with ≥5 points were considered by our group to be high-content videos. Videos with ≤4 points were considered low-content videos. Forty-nine (59 %) videos were low-content videos while 34 (41 %) were high-content videos. There was no association between number of views, number of comments, thumbs up, thumbs down or engagement score, and videos deemed high-content. Multiple regression analysis revealed bowel preparation videos on YouTube™ with length >4 minutes and non-patient authorship to be associated with high-content videos.

The use of hydrodynamic vortex separators and screening systems to improve water quality.

PubMed

Andoh, R Y G; Saul, A J

2003-01-01

The paper reviews the evolution of Hydrodynamic Vortex Separators (HDVS) in the context of application as high rate rotary flow separators for achieving water quality improvements to meet with regulatory requirements in Europe and North America. The types of HDVS and their application for the control of wet-weather discharges such as combined sewer overflows (CSOs), sanitary sewer overflows (SSOs) and stormwater are outlined and a number of myths surrounding their use, dispelled. Reference is made to outputs of peer reviewed comprehensive monitoring, evaluation and demonstration projects on pilot and full-scale installations to demonstrate the efficacy and extensive track record of these systems. Recent developments and innovations in HDVS technologies are discussed, focusing on their combined use as solids liquid separators, contact vessels for wastewater disinfection, the incorporation of self-cleansing screening devices for the control of aesthetic pollutants (e.g. floatables) and the use of computational modelling for optimisation.

Efficacy of umbilical cord cleansing with a single application of 4% chlorhexidine for the prevention of newborn infections in Uganda: study protocol for a randomized controlled trial.

2017-07-12

Yearly, nearly all the estimated worldwide 2.7 million neonatal deaths occur in low- and middle-income countries. Infections, including those affecting the umbilical cord (omphalitis), are a significant factor in approximately a third of these deaths. In fact, the odds of all-cause mortality are 46% higher among neonates with omphalitis than in those without. Five large randomized controlled trials in Asia and Sub-Saharan Africa (SSA) have examined the effect of multiple cord stump applications with 4% chlorhexidine (CHX) for at least 7 days on the risk of omphalitis and neonatal death. These studies, all community-based, show that multiple CHX applications reduced the risk of omphalitis. Of these trials, only one study from South Asia (the Bangladeshi study) and none from Africa examined the effect of a single application of CHX as soon as possible after birth. In this Bangladeshi trial, CHX led to a reduction in the risk of mild-moderate omphalitis and neonatal death. It is important, in an African setting, to explore the effect of a single application among health-facility births. A single application is programmatically much simpler to implement than daily applications for 7 days. Therefore, our study compares umbilical cord cleansing with a single application of 4% CHX at birth with dry cord care among Ugandan babies born in health facilities, on the risk of omphalitis and severe neonatal illness. The CHX study is a facility-based, individually randomized controlled trial that will be conducted among 4760 newborns in Uganda. The primary outcomes are severe illness and omphalitis during the neonatal period. Analysis will be by intention-to-treat. This study will provide novel evidence, from a Sub-Saharan African setting, of the effect of umbilical cord cleansing with a single application of 4% CHX at birth and identify modifiable risk factors for omphalitis.

2008-12-01

Colon preparation for a colonoscopy in children is a difficult task because of the unpalatable taste and large volume of cleansing solution that needs to be consumed to ensure a clean colon. Consequently, an unprepared colon frequently occurs in routine practices, which causes early termination and a repeated procedure. (1) To assess the effectiveness of polyethylene glycol solution (PEG 3350) in preparing the colon of children scheduled for a colonoscopy and (2) to investigate clinical markers associated with an adequate colon preparation before a colonoscopy. A total of 167 children scheduled for a colonoscopy. In a prospective study, children scheduled for a colonoscopy were given PEG 3350 solution (1.5 g/kg per day, up to 100 g/d) over a 4-day preparation period. Each day, a simple questionnaire that documents the amount of liquid consumed, adverse effects, and the number and consistency of stool was completed by the parents. After a colonoscopy procedure, the colon preparation was assigned a number grade. The data were later assessed and were compared to determine the association between the grade of cleansing and the frequency and/or consistency of stool during preparation. Colon preparation was completed in 149 children, 133 of whom were adequately prepared. Inadequate preparation was found in 16 children; the procedure was terminated prematurely in 2 of these patients because of unacceptable conditions. No significant adverse effects were noted. A number of >or=5 stools/d, and liquid stool consistency in the last 2 days of preparation were associated with adequate colon preparation. PEG 3350 solution is safe, efficacious, and tolerable for children. Stool frequency and consistency in the last 2 days of preparation were excellent markers (positive predictive value 91%-95%), which predict an adequately clean colon before a colonoscopy in children.

Whole-bowel irrigation for mechanical colon cleansing.

PubMed

Michael, K A; DiPiro, J T; Bowden, T A; Tedesco, F J

1985-01-01

The physiology, solution composition, indications, efficacy, and safety of whole-bowel irrigation (WBI) for mechanical bowel cleansing are reviewed. WBI with isotonic electrolyte solutions produces diarrhea when the infusion rate exceeds the capacity of the intestine to distend and absorb the solution. A number of solutions are used for WBI, including 0.9% sodium chloride, balanced electrolyte solutions, lactated Ringer's, mannitol, and electrolyte solutions containing polyethylene glycol 3350 (PEG). WBI solution administration rates vary from 15-90 mL/min, by oral ingestion or nasogastric tube, with total volumes ranging from 1 to 20 L. The onset of diarrhea occurs as soon as 20 minutes with clearing of the effluent as early as 90 minutes. Faster administration rates appear to shorten overall cleansing time. Two PEG-electrolyte lavage solutions (ELSs) have recently gained FDA approval. The recommended dosage rate is 1.2-1.8 L/hr orally or by nasogastric tube until rectal effluent is clear. In most patients, this requires a maximum of 4-6 L. Initial data indicate that PEG-ELSs are safe for elderly patients and for patients who have an increased risk of fluid overload, but these solutions have not been evaluated in children, pregnant women, or patients with inflammatory bowel disease. WBI is an effective alternative to other regimens for removing fecal material and reducing bowel lumen bacterial counts before colonoscopy and colorectal surgery. Retention of bacterial counts before colonoscopy and colorectal surgery. Retention of excess WBI solution may interfere with the quality of barium enema radiographs; this can be minimized by completing the irrigation the evening before the examination. Gastrointestinal side effects occur in about one third of the patients following WBI, but do not generally require discontinuing the irrigation. Solutions containing PEG with sodium sulfate as the primary electrolyte result in the least net water and electrolyte movement and are preferred over other solutions.

The purpose of this study was to assess the cosmetic appearance of commonly marketed facial cosmetics when used after the application of metronidazole gel 1%. An observational. open-label, single-site study was conducted with women (N=30) aged 20 to 75 years and diagnosed with moderate papulopustular rosacea (investigator global severity score of 3). After cleansing the face with a gentle skin cleanser, participants applied metronidazole gel 1% once daily before applying their usual facial foundation. Two surveys were conducted: (1) investigator assessment of cosmetic appearance; and (2) participant assessment of cosmetic appearance. The investigator also evaluated erythema, disease severity, and tolerability at baseline and week 2. Adverse events were collected. The 28 per-protocol (PP) participants had a mean age (standard deviation [SD]) of 54.0 (10.3) years and a mean duration (SD) of rosacea of 15.4 (13.2) years. The median response score for both the investigator and participant assessments of cosmetic appearance was 10 (best) for each survey question. Signs and symptoms of rosacea did not increase with use of metronidazole gel 1% and the participants' selected cosmetic regimen. At baseline all 28 participants were classified as having moderate erythema. At week 2, 18 (64%) participants were classified as having moderate erythema and 10 (36%) mild. At baseline all 28 (100%) participants were classified as having moderate rosacea according to the investigator global severity score. At week 2, 10 (36%) participants were classified as mild and 18 (64%) moderate. In addition, few participants reported cutaneous irritation during the study. At week 2, 10 participants had dryness, 2 had itching, 8 had scaling, and 2 had stinging/burning. According to surveys completed by the investigator and the participants themselves, most participants had a good cosmetic appearance with their facial foundation cosmetics that were applied after metronidazole gel 1%. The use of various cosmetic regimens after application of metronidazole gel 1% did not cause rosacea symptoms to worsen and treatment was well-tolerated.

Young, Daniel L; Chakravarthy, Debashish; Drower, Edward; Reyna, Roxana

2014-01-01

Cleansing, moisturizing, and protecting neonatal skin is important, but literature evaluating specific product lines is limited. The purpose of this study was to measure the influence of a skin care product line on overall skin condition, perineal erythema, and pain when applied to neonates in a neonatal intensive care unit (NICU). This was an open label, descriptive study. Comparisons were made between measurements taken at the beginning of the study to those at the end, on the same subjects. The study was conducted in a 41-bed NICU at Driscoll Children's Hospital in Corpus Christi, Texas, that serves 31 counties in the region. This NICU treats children needing level 2 and 3 care, with a 1:1 or 2:1 nurse staffing ratio. This is not a birthing center; patients come from other community hospitals. Twenty-nine neonates participated in the study; their average body weight was 1.39 kg (3.06 lb) and their average gestation was 31.7 weeks. A skin care product line was introduced into a neonatal intensive care unit for 14 days. The products included 2 cleansers, 2 moisturizers, and a skin protectant with zinc oxide. Three outcome measures were tracked: Neonatal Skin Condition Score (NSCS), Skin Erythema Scale (SES), and pain. Nurses were also given a product evaluation survey. Descriptive statistics were used to report percentages and trends. Paired t tests were used to compare the mean NSCS, SES, and pain scores from the first 2 days a subject was in the study to the mean of the scores from the last 2 days they were in the study. Subjects experienced approximately 1774 exposures to individual products during data collection. No differences were found in pain scores (P = .132), SES score (P = .059), or NSCS (P = .603) when mean values were compared at the beginning and end of the study. Analysis of the product evaluation survey for questions on cleaning, moisturizing, and reducing discomfort found that more than 90% of nurses ranked the new products as better than or equal to similar products used previously. Use of a skin care product line was not associated with significant increases in overall neonatal skin condition measured with the NSCS, perineal erythema measured with the SES, or pain. The nurses caring for the subjects in this study prefer these products to others they have used in the past.

1974-01-01

Recent research and development programs have established the ability of the zero gravity whole body shower to maintain a comfortable environment in which the crewman can safely cleanse and dry the body. The purpose of this program was to further advance the technology of whole body bathing and to demonstrate technological readiness including in-flight maintenance by component replacement for flight applications. Three task efforts of this program are discussed. Conceptual designs and system tradeoffs were accomplished in task 1. Task 2 involved the formulation of preliminary and final designs for the shower, while task 3 included the fabrication and test of the shower assembly. Particular attention is paid to the evaluation and correction of test anomalies during the final phase of the program.

Laser Angioplasty

The principal method of dealing with coronary artery blockage is bypass surgery. A non-surgical alternative available to some patients is balloon angioplasty. For several years, medical researchers have been exploring another alternative that would help a wider circle of patients than the balloon treatment and entail less risk than bypass surgery. A research group is on the verge of an exciting development: laser angioplasty with a 'cool' type of laser, called an excimer laser, that does not damage blood vessel walls and offers non-surgical cleansing of clogged arteries with extraordinary precision. The system is the Dymer 200+ Excimer Laser Angioplasty System, developed by Advanced Intraventional Systems. Used in human clinical tests since 1987, the system is the first fully integrated 'cool' laser capable of generating the requisite laser energy and delivering the energy to target arteries. Thirteen research hospitals in the U.S. have purchased Dymer 200+ systems and used them in clinical trials in 121 peripheral and 555 coronary artery cases. The success rate in opening blocked coronary arteries is 85 percent, with fewer complications than in balloon angioplasty. Food and Drug Administration approval for the system is hoped for in the latter part of 1990. * Advanced Intraventional Systems became Spectranetics in 1994 and discontinued the product.

Human microbiota-associated (HMA) mice are an important model to study the relationship between liver diseases and intestinal microbiota. We describe a new method to humanize conventional mice based on bowel cleansing with polyethylene glycol followed by fecal microbiota transplantation (FMT) from a human donor. Four successive bowel cleansings were sufficient to empty the intestine and decrease the microbiota by 90%. We then compared four different strategies based on the frequency of FMT over four weeks: (1) twice a week; (2) once a week; (3) two FMTs; (4) one FMT. We were able to transfer human bacteria to mice, irrespective of the strategy used. We detected human bacteria after four weeks, even if only one FMT was performed, but there was a shift of the microbiota over time. FMT twice a week for four weeks was too frequent and perturbed the stability of the newly formed ecosystem. FMT once a week appears to be the best compromise as it allowed engraftment of Faecalibacterium, and a higher diversity of bacteria belonging to the Bacteroidales order. Our easy to establish HMA mouse model could be used as an alternative to classical HMA mice to study the relationship between the liver and the microbiota.

Modelling lake-water photochemistry: three-decade assessment of the steady-state concentration of photoreactive transients (·OH, CO3(-·) and (3)CDOM(∗)) in the surface water of polymictic Lake Peipsi (Estonia/Russia).

2013-03-01

Over the last 3-4 decades, Lake Peipsi water (sampling site A, middle part of the lake, and site B, northern part) has experienced a statistically significant increase of bicarbonate, pH, chemical oxygen demand, nitrate (and nitrite in site B), due to combination of climate change and eutrophication. By photochemical modelling, we predicted a statistically significant decrease of radicals ·OH and CO3(-·) (site A, by 45% and 35%, respectively) and an increase of triplet states of chromophoric dissolved organic matter ((3)CDOM(∗); site B, by ∼25%). These species are involved in pollutant degradation, but formation of harmful by-products is more likely with (3)CDOM(∗) than with ·OH. Therefore, the photochemical self-cleansing ability of Lake Peipsi probably decreased with time, due to combined effects of climate change and eutrophication. In different environments (e.g. Lake Maggiore, NW Italy), ecosystem restoration policies had the additional advantage of enhancing sunlight-driven detoxification, suggesting that photochemical self-cleansing would be positively correlated with lake water quality.

Foot burns: epidemiology and management.

PubMed

Hemington-Gorse, S; Pellard, S; Wilson-Jones, N; Potokar, T

2007-12-01

This is a retrospective study of the epidemiology and management of isolated foot burns presenting to the Welsh Centre for Burns from January 1998 to December 2002. A total of 289 were treated of which 233 were included in this study. Approximately 40% were in the paediatric age group and the gender distribution varied dramatically for adults and children. In the adult group the male:female ratio was 3.5:1, however in the paediatric group the male:female ratio was more equal (1.6:1). Scald burns (65%) formed the largest group in children and scald (35%) and chemical burns (32%) in adults. Foot burns have a complication rate of 18% and prolonged hospital stay. Complications include hypertrophic scarring, graft loss/delayed healing and wound infection. Although isolated foot burns represent a small body surface area, over half require treatment as in patients to allow for initial aggressive conservative management of elevation and regular wound cleansing to avoid complications. This study suggests a protocol for the initial acute management of foot burns. This protocol states immediate referral of all foot burns to a burn centre, admission of these burns for 24-48 h for elevation, regular wound cleansing with change of dressings and prophylactic antibiotics.

Chronic constipation is a common functional disorder of the gastrointestinal tract, affecting up to 35% of the general population, and especially the elderly. However, its definition as perceived by the patient can vary, making it difficult to understand the problem and find appropriate therapeutic measures. The approach to chronic constipation, thus, needs a thorough understanding of the patient's complaint and the main pathophysiological mechanism requiring treatment. Lifestyle changes do not usually meet with complete patient satisfaction. Other treatments include different types of laxatives. Of these, osmotic laxatives appear one of the most effective and are, therefore, frequently prescribed. This review will cover the topic of osmotic laxatives, specifically focusing on polyethylene glycol (PEG/macrogol 4000) in chronic constipation and as a key agent for bowel cleansing prior to colonoscopy. PEG formulations, including macrogol 4000, are safe, effective treatments for constipation, even in children and elderly patients. Macrogol 4000 may well be more palatable than combined formulations (macrogol 3350 with electrolytes), which could help improve adherence to the long-term treatment required for chronic constipation. PEG/macrogol is also recommended as an effective option for bowel cleansing prior to colonoscopy. The improved cost-effectiveness of macrogol over other commonly prescribed laxatives, such as lactulose, should be taken into consideration.

To establish the effectiveness of human breast milk and barrier cream (40% zinc oxide with cod liver oil formulation) applied for the skincare of newborns in the neonatal intensive care unit on the healing process of diaper dermatitis. Diaper dermatitis is the most common dermatological condition in newborns who are cared for in the neonatal intensive care unit. Recently, there are several kinds of complementary skincare methods suggested for newborns, such as sunflower oil, human breast milk, etc. Also, some chemical formulations are still being used in many neonatal intensive care units. Randomised controlled, prospective, experimental. This study was carried out with a population including term and preterm newborns who developed diaper rash while being treated in the neonatal intensive care unit of a university hospital in Istanbul between February-October 2010. On completion of the research, a total of 63 newborns from human breast milk (n = 30) and barrier cream (n = 33) groups were contacted. Genders, mean gestation weeks, feeding method, antibiotic use, diaper area cleansing methods, diaper brands and prelesion scores of newborns in both groups were found to be comparable (p > 0·05). There was no statistically significant difference (p = 0.294) between the groups in terms of mean number of clinical improvement days, but postlesion score of the barrier cream group was statistically significantly lower (p = 0·002) than the human breast milk group. Barrier cream delivers more effective results than treatment with human breast milk, particularly in the treatment of newborns with moderate to severe dermatitis in the result of the study. This study will shed light on nursing care of skin for newborns who are treated in neonatal intensive care unit. © 2013 Blackwell Publishing Ltd.

Is water exchange superior to water immersion for colonoscopy? A systematic review and meta-analysis.

PubMed

2018-06-05

Recently, water exchange (WE) instead of water immersion (WI) for colonoscopy has been proposed to decrease pain and improve adenoma detection rate (ADR). This systematic review and meta-analysis is conducted to assess whether WE is superior to WI based on the published randomized controlled trials (RCTs). We searched studies from PubMed, Cochrane Central Register of Controlled Trials, EMBASE, and MEDLINE. Only RCTs were eligible for our study. The pooled risk ratios (RRs), pooled mean difference (MD), and pooled 95% confidence intervals (CIs) were calculated by using the fixed-effects model or random-effects model based on heterogeneity. Five RCTs consisting of 2229 colonoscopies were included in this study. WE was associated with a significantly higher ADR than WI (RR = 1.18; CI = 1.05-1.32; P = 0.004), especially in right colon (RR = 1.31; CI = 1.07-1.61; P = 0.01). Compared with WI, WE was confirmed with lower pain score, higher Boston Bowel Preparation Scale score, but more infused water during insertion. There was no statistical difference between WE and WI in cecal intubation rate and the number of patients who had willingness to repeat the examination. Furthermore, both total procedure time and cecal intubation time in WE were significantly longer than that in WI (MD = 2.66; CI = 1.42-3.90; P < 0.0001; vs MD = 4.58; CI = 4.01-5.15; P < 0.0001). This meta-analysis supports the hypothesis that WE is superior to WI in improving ADR, attenuating insertion pain and providing better bowel cleansing, but inferior in time and consumption of infused water consumption during insertion.

Background Ethyl-2-cyanoacrylate (ECA) is a tissue adhesive material applied to close superficial wounds. The aim of this study was to explore the benefits of cyanoacrylates in the emergency department in children with current application with regard to cost-effectiveness, satisfaction and long follow up. Findings Patients were treated after assignment of the consent with an explanation by the relatives in a tertiary emergency department (ED), 2007. The evaluation was based on different superficial wound repairs due to blunt trauma within a 2-hour time period (<6 hours), and small wounds (≤3 cm). These wounds were cleansed with serum sale and then dried with gauze. Wound repairs were observed for six months in order to observe the tissue changes. The patient's age, sex, indication, application time, pain score, cost, additional tending (if needed), complications, and cosmetic satisfaction were recorded. A total of 9 patients were evaluated and followed for 6 months. Except for one, all children were treated without any serious complications. ECA was cost-effective, time-saving, and provided successful repair satisfaction by a blinded plastic surgeon and patient/parents. Conclusion This report displayed the pediatric effective use of cyanoacrylates, even in non- traditional repairs in the emergency departments. PMID:19594954

Currently, there is no standardized protocol for bowel preparation before small bowel capsule endoscopy (SBCE). This study aimed to investigate the effect of simethicone combined with polyethylene glycol (PEG) on the visualization quality (VQ) of the SBCE in patients with or without known or suspected Crohn's disease (CD). This observational, prospective, single-center study included consecutive patients undergoing a SBCE between 2007 and 2008. Patients received either a standard bowel cleansing preparation of 2 L PEG and 80 mg simethicone orally 12 and 1 h before SBCE respectively (Group A) or only PEG (Group B). VQ, based on scores for luminal bubbles in frames taken from the small intestine, examination completeness, SBCE diagnostic yield, gastric and small bowel transit times were recorded. Of the 115 patients finally included (Group A, n=56 and Group B, n=59) the cecum was visualized in 103 (89.6%). Simethicone overall improved the VQ in the proximal [OR: 2.43 (95%CI: 1.08-5.45), P=0.032] but not in the distal bowel segment (P=0.064). Nevertheless, this effect was not observed in patients undergoing SBCE for either known or suspected CD. Simethicone as an adjunct to PEG for bowel preparation in patients undergoing SBCE significantly improved the VQ in non-CD patients.

Spacecraft disinfectant/cleansing agent development

NASA Technical Reports Server (NTRS)

Abbate, M.

1977-01-01

The sanitation agent container, which was selected in a trade off study, employs two chambers, a rigid outer container and an inner flexible bladder. The bladder contains the sanitation agent formulation and its release is controlled by a manually operated valve. The outer container holds a high pressure vapor. There is no void in the bladder which makes the package operation independent of orientation and therefore usable in zero gravity. Foam is developed by a low boiling point fluid or dissolved in the product. When the product is dispensed at atmospheric presure, the evolved gas or vapor whips up a goam in the valve. The sanitation agents were initially formulated with freons which produces an excellent foam. However freon is incompatible with the life support system and was replaced with carbon dioxide dissolved at high pressure. The CO2 system may limit high temperature exposure to prevent leakage or package distortion. The sanitation agents have been shown to be effective in cleaning soils from personnel and material.

A Galactic Binary Detection Pipeline

Littenberg, Tyson B.

2011-01-01

The Galaxy is suspected to contain hundreds of millions of binary white dwarf systems, a large fraction of which will have sufficiently small orbital period to emit gravitational radiation in band for space-based gravitational wave detectors such as the Laser Interferometer Space Antenna (LISA). LISA's main science goal is the detection of cosmological events (supermassive black hole mergers, etc.) however the gravitational signal from the galaxy will be the dominant contribution to the data - including instrumental noise over approximately two decades in frequency. The catalogue of detectable binary systems will serve as an unparalleled means of studying the Galaxy. Furthermore, to maximize the scientific return from the mission, the data must be "cleansed" of the galactic foreground. We will present an algorithm that can accurately resolve and subtract 2:: 10000 of these sources from simulated data supplied by the Mock LISA Data Challenge Task Force. Using the time evolution of the gravitational wave frequency, we will reconstruct the position of the recovered binaries and show how LISA will sample the entire compact binary population in the Galaxy.

Life cycle of a data warehousing project in healthcare.

Hill Physicians Medical Group (and its medical management firm, PriMed Management) early on recognized the need for a data warehouse. Management demanded that data from many sources be integrated, cleansed, and formatted. As a first step, an operational data store (ODS) was built and populated with data from the main transactional system; encounter data were added. The ODS has served its purpose well and has whetted management's appetite for more information and faster, more reliable access, all in one location. PriMed hired Annams Systems Consulting (Annams) for this effort. A team was formed, made up of consultants from Annams and members of PriMed's information services (IS) team. The "classical" approach is being taken: enhancing the ODS, which is largely normalized in structure, and integrating data from various sources, along with enforcing business rules. The team is designing and implementing data marts and a "star schema" style of data modeling--a useful tool for management to evaluate results before investing further.

Some national guidelines recommend the use of water alone for napkin cleansing. Yet, there is a readiness, amongst many parents, to use baby wipes. Evidence from randomised controlled trials, of the effect of baby wipes on newborn skin integrity is lacking. We conducted a study to examine the hypothesis that the use of a specifically formulated cleansing wipe on the napkin area of newborn infants (<1 month) has an equivalent effect on skin hydration when compared with using cotton wool and water (usual care). A prospective, assessor-blinded, randomised controlled equivalence trial was conducted during 2010. Healthy, term babies (n=280), recruited within 48 hours of birth, were randomly assigned to have their napkin area cleansed with an alcohol-free baby wipe (140 babies) or cotton wool and water (140 babies). Primary outcome was change in hydration from within 48 hours of birth to 4 weeks post-birth. Secondary outcomes comprised changes in trans-epidermal water loss, skin surface pH and erythema, presence of microbial skin contaminants/irritants at 4 weeks and napkin dermatitis reported by midwife at 4 weeks and mother during the 4 weeks. Complete hydration data were obtained for 254 (90.7 %) babies. Wipes were shown to be equivalent to water and cotton wool in terms of skin hydration (intention-to-treat analysis: wipes 65.4 (SD 12.4) vs. water 63.5 (14.2), p=0.47, 95% CI -2.5 to 4.2; per protocol analysis: wipes 64.6 (12.4) vs. water 63.6 (14.3), p=0.53, 95% CI -2.4 to 4.2). No significant differences were found in the secondary outcomes, except for maternal-reported napkin dermatitis, which was higher in the water group (p=0.025 for complete responses). Baby wipes had an equivalent effect on skin hydration when compared with cotton wool and water. We found no evidence of any adverse effects of using these wipes. These findings offer reassurance to parents who choose to use baby wipes and to health professionals who support their use. Current Controlled Trials ISRCTN86207019.

Summary Background Omphalitis contributes to neonatal morbidity and mortality in developing countries. Umbilical cord cleansing with antiseptics might reduce infection and mortality risk, but has not been rigorously investigated. Methods In our community-based, cluster-randomised trial, 413 communities in Sarlahi, Nepal, were randomly assigned to one of three cord-care regimens. 4934 infants were assigned to 4·0% chlorhexidine, 5107 to cleansing with soap and water, and 5082 to dry cord care. In intervention clusters, the newborn cord was cleansed in the home on days 1−4, 6, 8, and 10. In all clusters, the cord was examined for signs of infection (pus, redness, or swelling) on these visits and in follow-up visits on days 12, 14, 21, and 28. Incidence of omphalitis was defined under three sign-based algorithms, with increasing severity. Infant vital status was recorded for 28 completed days. The primary outcomes were incidence of neonatal omphalitis and neonatal mortality. Analysis was by intention-to-treat. This trial is registered with Clinicaltrials.gov, number NCT00109616. Findings Frequency of omphalitis by all three definitions was reduced significantly in the chlorhexidine group. Severe omphalitis in chlorhexidine clusters was reduced by 75% (incidence rate ratio 0·25, 95% CI 0·12−0·53; 13 infections/4839 neonatal periods) compared with dry cord-care clusters (52/4930). Neonatal mortality was 24% lower in the chlorhexidine group (relative risk 0·76 [95% CI 0·55−1·04]) than in the dry cord care group. In infants enrolled within the first 24 h, mortality was significantly reduced by 34% in the chlorhexidine group (0·66 [0·46−0·95]). Soap and water did not reduce infection or mortality risk. Interpretation Recommendations for dry cord care should be reconsidered on the basis of these findings that early antisepsis with chlorhexidine of the umbilical cord reduces local cord infections and overall neonatal mortality.

Katharsis of the skin: Peeling applications and agents of chemical peelings in Greek medical textbooks of Graeco-Roman antiquity.

PubMed

2018-04-28

Recipes for peelings date back to medical texts of old Egypt. The oldest medical papyri contain recipes for "improving beauty of the skin" and "removing wrinkles" by use of agents like salt and soda. The Egyptian Queen Cleopatra (69-30 BC) is said to have taken bathes in donkey's milk in order to improve the beauty of her skin. However, little is known about other agents and peeling applications in later Greek medical textbooks. We will discover new agents and describe ancient peeling applications. First, we will have to identify ancient Greek medical terms for the modern terms "peeling" and "chemical peeling". Second, based on the identified terms we will perform a systematic fulltext search for agents in original sources. Third, we will categorize the results into three peeling applications: (1) cleansing, (2) aesthetical improvement of the skin, and (3) therapy of dermatological diseases. We performed a full systematic keyword search with the identified Greek terms in databases of ancient Greek texts. Our keywords for peeling and chemical peeling are "smēxis" and "trīpsis". Our keywords for agents of peeling and chemical peeling are "smégmata", "rhýmmata", "kathartiká", and "trímmata". Diocles (4 th century BC) was the first one who mentioned "smēxis" and "trīpsis" as parts of daily cleansing routine. Criton (2 nd century AD) wrote about peeling applications, but any reference to the agents is lost. Antyllos (2 nd century AD) composed three lists of peeling applications including agents. Greek medical textbooks of Graeco-Roman antiquity report several peeling applications like cleansing, brightening, darkening, softening, and aesthetical improvement of the skin by use of peeling and chemical peeling, as well as therapy of dermatological diseases. There are 27 ancient agents for what is contemporarily called peeling and chemical peeling. We discovered more specific agents than hitherto known to research. This article is protected by copyright.

Regular cleaning of dentures is essential to the oral and general health of denture wearers. Only limited systematic data are available on the recommendations that dental health care professionals (DHCPs) make to patients for denture cleaning. Data on denture wearers' cleaning regimens are also lacking. The purpose of this study was to provide data on recommendations that DHCPs make to patients for denture cleaning and on the cleaning regimens of denture wearers. DHCPs (n=613), including dentists and hygienists, were surveyed in developed (Japan, USA, Italy) and developing (Brazil, India) countries. A questionnaire assessing a range of denture cleaning recommendations was used. The questions addressed products, frequency, how to use remedies, the suggested dilution and duration of cleansing treatment, the location of dentures while cleaning, and the reasoning behind the recommendation of particular products or modes of treatment. Denture cleansing methods and the routine of denture wearers in developed and developing countries were also surveyed with a questionnaire (n=2862) and a 1-week diary (n=1462). An average of more than 2 treatments was recommended by DHCPs. Specialist denture cleanser tablets, "regular" toothpaste, mouthwash, soap and water, denture paste, foam or liquid denture cleanser, and dishwashing detergents were most commonly recommended; other product recommendations included baking soda, vinegar, salt water, and bleach. More than 10% of DHCPs made no primary recommendation on cleaning. Denture tablets were more commonly recommended in developed countries, whereas toothpaste was the most common recommendation in developing countries. Denture wearers used products and methods similar to those recommended by DHCPs. Toothpaste, water, and mouthwash were used more frequently than denture tablets. More than 75% of denture wearers reported using denture cleanser tablets for more than 5 minutes, whereas soap and toothpaste were typically used for less than 2 minutes. DHCP recommendations and denture wearer habits are diverse, with no consensus on the most appropriate denture cleaning methods. This reflects a lack of clear, systematic evidence upon which to base recommendations. Copyright © 2016 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

Studies using a 755 nm picosecond laser with a focus lens array have been reported to be effective for facial wrinkles and pigmentation. This study reports the safety and efficacy using a shorter interval of 2-3 weeks between treatments. Nineteen female subjects and one male subject, primarily Fitzpatrick skin types II and III (one skin type I), who had mild to moderate wrinkles and sun-induced pigmentation were enrolled and treated using the 755 nm PicoSure Laser with focus lens array. The skin was cleansed then wiped with an alcohol wipe prior to treatment. Lidocaine 30% ointment and/or forced air cooling could be used to increase subject comfort. Adjacent pulses, with minimal overlap (10% or less), were delivered to the full face. Subjects received four treatments, performed at 2-3-week intervals. The laser energy used was 0.71 J/cm 2 . The physician administered 3-7 passes with an average total of 6,253 pulses per treatment. Follow-up visits occurred at 1 and 3 months post-last treatment at which the physician scored satisfaction and improvement and subjects scored satisfaction and likelihood to recommend to others. The most common side effects were mild swelling, pain, redness, and crusting, most of which subsided within hours of the treatment, with the latest resolving within 48 hours. This is similar to a previous reported study (Weiss et al. ASLMS 2015) where treatments were performed every 6 weeks with side effects resolving within 24 hours. At the 1 and 3 month follow-up visits, 94% (n = 19) and 93% (n = 15) of subjects scored themselves as satisfied or extremely satisfied with their overall results and 81% and 93% were likely to recommend the treatment based on global assessment, respectively. The treating physician was satisfied with 93% of subject's overall results. Three blinded evaluators were able to correctly identify the baseline from post-treatment photographs in 77% of the subjects at the 1 month follow-up and 69% of the subjects at the 3 month follow-up, on average. The average treatment pain score was 4.2 on a 1-10 scale. A compressed treatment interval expedites results without increasing side effects and resulted in a high physician and subject satisfaction rate. Lasers Surg.

 Lubiprostone has been reported to be an anti-constipation drug. The aim of the study was to investigate the usefulness of lubiprostone both for bowel preparation and as a propulsive agent in small bowel endoscopy.  This was a double-blind, placebo-controlled, 2-way crossover study of subjects who volunteered to undergo capsule endoscopy (CE). A total of 20 subjects (16 male and 4 female volunteers) were randomly assigned to receive a 24-μg tablet of lubiprostone 120 minutes prior to capsule ingestion for CE (L regimen), or a placebo tablet 120 minutes prior to capsule ingestion for CE (P regimen). Main outcome was gastric transit time (GTT) and small-bowel transit time (SBTT). Secondary outcome was adequacy of small-bowel cleansing and the fluid score in the small bowel. The quality of the capsule endoscopic images and fluid in the small bowel were assessed on 5-point scale.  The capsule passed into the small bowel in all cases. Median GTT was 57.3 (3 - 221) minutes for the P regimen and 61.3 (10 - 218) minutes for the L regimen ( P  = 0.836). Median SBTT was 245.0 (164 - 353) minutes for the P regimen and 228.05 (116 - 502) minutes for the L regimen ( P  = 0.501). The image quality score in the small bowel was 3.05 ± 1.08 for the P regimen and 3.80 ± 0.49 for the L regimen ( P  < 0.001). The fluid score in the small bowel was 2.04 ± 1.58 for the P regimen and 2.72 ± 1.43 for the L regimen ( P  < 0.001). There was a significant difference between the 2 regimens with regard to image quality. The fluid score was more plentiful for the L regimen than for the P regimen. There were no cases of capsule retention or serious adverse events in this study.  Our study showed that use of lubiprostone prior to CE significantly improved visualization of the small bowel during CE as a result of inducing fluid secretion into the small bowel.

There is no consensus regarding the diagnostic and therapeutic strategy for pubic osteomyelitis secondary to pelvic pressure sores. Diagnosis is often difficult and bone biopsies with microbiological and anatomical-pathological examination remain the gold standard. The rate of cicatrisation of pressure sores is low. Cleansing and negative pressure treatment are key elements of the treatment. Optimising the care management with medical-surgical collaboration is being studied in the Ostear protocol.

Hand Washing Induces a Clean Slate Effect in Moral Judgments: A Pupillometry and Eye-Tracking Study

PubMed Central

Kaspar, Kai; Krapp, Vanessa; König, Peter

2015-01-01

Physical cleansing is commonly understood to protect us against physical contamination. However, recent studies showed additional effects on moral judgments. Under the heading of the “Macbeth effect” direct links between bodily cleansing and one’s own moral purity have been demonstrated. Here we investigate (1) how moral judgments develop over time and how they are altered by hand washing, (2) whether changes in moral judgments can be explained by altered information sampling from the environment, and (3) whether hand washing affects emotional arousal. Using a pre-post control group design, we found that morality ratings of morally good and bad scenes acquired more extreme values in the control group over time, an effect that was fully counteracted by intermediate hand washing. This result supports the notion of a clean slate effect by hand washing. Thereby, eye-tracking data did not uncover differences in eye movement behavior that may explain differences in moral judgments. Thus, the clean slate effect is not due to altered information sampling from the environment. Finally, compared to the control group, pupil diameter decreased after hand washing, thus demonstrating a direct physiological effect. The results shed light on the physiological mechanisms behind this type of embodiment phenomenon. PMID:25994083

A Load-Based Temperature Prediction Model for Anomaly Detection

NASA Astrophysics Data System (ADS)

Sobhani, Masoud

Electric load forecasting, as a basic requirement for the decision-making in power utilities, has been improved in various aspects in the past decades. Many factors may affect the accuracy of the load forecasts, such as data quality, goodness of the underlying model and load composition. Due to the strong correlation between the input variables (e.g., weather and calendar variables) and the load, the quality of input data plays a vital role in forecasting practices. Even if the forecasting model were able to capture most of the salient features of the load, a low quality input data may result in inaccurate forecasts. Most of the data cleansing efforts in the load forecasting literature have been devoted to the load data. Few studies focused on weather data cleansing for load forecasting. This research proposes an anomaly detection method for the temperature data. The method consists of two components: a load-based temperature prediction model and a detection technique. The effectiveness of the proposed method is demonstrated through two case studies: one based on the data from the Global Energy Forecasting Competition 2014, and the other based on the data published by ISO New England. The results show that by removing the detected observations from the original input data, the final load forecast accuracy is enhanced.

To test the use of meglumine and sodium diatrizoate (Gastrografin) as an agent for preoperative mechanical bowel preparation. Prospective randomised comparison. County general hospital, Greece. 58 patients listed for elective colorectal operations were randomly divided into 2 groups. The first (n = 30) was given Gastrografin 200 ml orally for 2 consecutive days before operation, and the second (n = 28) was given Ringer's solution through a nasogastric tube. Tolerability, acceptability, quality of cleansing, and complications. There were no disturbances in electrolyte concentrations, and other laboratory variables also remained unchanged. Two patients treated with Ringer's solution had appreciable increases in arterial blood pressure, but there were no significant overall changes. About half the patients given Ringer's felt nauseated and a third vomited. Such symptoms were uncommon in patients treated with Gastrografin (p < 0.01). 28/30 and 26/28 (93%) had a clean colonic lumen at operation, whereas in the reminder the lumen was evaluated as containing "slight residue". There were no operation-related complications. Gastrografin can be used successfully as an agent for mechanical bowel preparation before elective colorectal surgery, as it gives equally good cleansing results compared with the established method of whole gut irrigation. It also seems to be better tolerated and accepted by patients.

A new fractional order derivative based active contour model for colon wall segmentation

2018-02-01

Segmentation of colon wall plays an important role in advancing computed tomographic colonography (CTC) toward a screening modality. Due to the low contrast of CT attenuation around colon wall, accurate segmentation of the boundary of both inner and outer wall is very challenging. In this paper, based on the geodesic active contour model, we develop a new model for colon wall segmentation. First, tagged materials in CTC images were automatically removed via a partial volume (PV) based electronic colon cleansing (ECC) strategy. We then present a new fractional order derivative based active contour model to segment the volumetric colon wall from the cleansed CTC images. In this model, the regionbased Chan-Vese model is incorporated as an energy term to the whole model so that not only edge/gradient information but also region/volume information is taken into account in the segmentation process. Furthermore, a fractional order differentiation derivative energy term is also developed in the new model to preserve the low frequency information and improve the noise immunity of the new segmentation model. The proposed colon wall segmentation approach was validated on 16 patient CTC scans. Experimental results indicate that the present scheme is very promising towards automatically segmenting colon wall, thus facilitating computer aided detection of initial colonic polyp candidates via CTC.

The objective of this research was to develop methods to conserve water necessary to cleanse beef heads prior to USDA-FSIS inspection. This was to be accomplished by establishing a baseline for the minimum amount of water necessary to adequately wash a head and application of image analysis to provide an objective measure of head cleaning. Twenty-one beef heads were manually washed during the harvest process. An average 18.75 L (2.49 SD) and a maximum of 23.88 L were required to cleanse the heads to USDA-FSIS standards. Digital images were captured before and after manual washing then evaluated for percentage red saturation using commercially available image analysis software. A decaying exponential curve extracted from these data indicated that as wash water increased beyond 20 L the impact on red saturation decreased. At 4 sigma from the mean of 18.75 L, red saturation is 16.0 percent, at which logistic regression analysis indicates 99.994 percent of heads would be accepted for inspection, or less than 1 head in 15,000 would be rejected. Reducing to 3 sigma would increase red saturation to 27.6 percent, for which 99.730 percent of heads likely would be accepted (less than 1 in 370 would be rejected). Copyright 2009 Elsevier Ltd.

2006-02-01

Whole gut lavage with a polyethylene glycol electrolyte solution (PEG) is a common bowel cleansing method for diagnostic and therapeutic colon interventions. Absorption of orally administered PEG from the gastrointestinal tract in healthy human beings is generally considered to be poor. In patients with inflammatory bowel disease (IBD), intestinal permeability and PEG absorption were previously reported to be higher than in normal subjects. In the current study, we investigated the absorption of PEG 3350 in patients undergoing routine gut lavage. Urine specimens were collected for 8 hours in 24 patients undergoing bowel cleansing with PEG 3350 for colonoscopy. The urinary excretion of PEG 3350, measured by size exclusion chromatography, ranged between 0.01 and 0.51 % of the ingested amount, corresponding to 5.8 and 896 mg in absolute amounts, respectively. Mean PEG excretion in patients with impaired mucosa such as inflammation or ulceration of the intestine (0.24 % +/- 0.19, n = 11) was not significantly higher (p = 0.173) compared to that in subjects with macroscopically normal intestinal mucosa (0.13 % +/- 0.13, n = 13). The results indicate that intestinal absorption of PEG 3350 is higher than previously assumed and underlies a strong inter-individual variation. Inflammatory changes of the intestine do not necessarily lead to a significantly higher permeability of PEG.

Reports about the nature of the ingredients responsible for allergic contact dermatitis caused by specific cosmetic products are scarce. Between January 2000 and December 2010, the specific cosmetic products having caused allergic contact dermatitis, as well as the individual allergenic cosmetic ingredients present in them, were recorded by use of a standardized form. Among 11 different categories of cosmetic product, skin care products, followed by hair care and body-cleansing products, were most often involved. The presence of the allergenic ingredient(s) in a specific cosmetic product was confirmed according to the ingredient label in 959 of 1448 records. Six hundred and twenty-one of 959 concerned non-fragrance components, preservatives being responsible for 58% of them. Reactions to formaldehyde and formaldehyde-releasers were most often correlated with body-cleansing products, particularly 2-bromo-2-nitropropane-1,3-diol and skin care products. They were followed by the methylchloroisothiazolinone/methylisothiazolinone mixture, most frequently found as allergens in hair care and intimate hygiene products, and facial cleansers (in the last category together with diazolidinyl urea). Octocrylene was by far the most frequent (photo)allergen in sun care products. This study provides information on the presence and frequency of allergens in specific causal cosmetic products. © 2011 John Wiley & Sons A/S.

To examine variation in feminine hygiene practices as a function of increasing age. A nonexperimental, descriptive research design with study sample stratified by age. Women over 18 years of age. Of 713 women who completed and returned the feminine hygiene practices questionnaire, 180 were younger than 41 years, 171 were 41-48 years, 184 were 49-57 years, and 178 were 58 years or older. All participants were members of a California professional home economics organization. A 40-item feminine hygiene practices questionnaire dealing with body cleansing practices, feminine products usage, and both general and specific menses collection and protection practices. Significant age-related differences were found in several areas of body cleansing and feminine products usage, including sponge bathing and use of feminine and deodorant spray, wet wipes, and panty liners. In all age groups, 20-30% of women reported douching, even in the face of continued reports of the dangers in this practice. In addition, reduced numbers of women (n = 245) in all age groups reported washing hands before using tampons or pads, although more (n = 314) reported washing their hands afterward. Continuing education about proper feminine hygiene practices, especially regarding douching and handwashing before and after genitourinary contact, will be important across all age groups.

The PuriLens contact lens system is indicated for cleaning and disinfection of soft (hydrophilic) contact lenses by means of subsonic agitation to remove lens deposits and microorganisms, and ultraviolet irradiation of the storage solution for disinfection. The capacity of the PuriLens system to disinfect storage solutions contaminated with known concentrations of Staphylococcus aureus, Pseudomonas aeruginosa, and Acanthamoeba species was evaluated. An in vitro assessment of the antibacterial and antiparasitic efficacy of the PuriLens system was performed. Separated batches of the storage solution for the cleansing system were contaminated with stock strains of S. aureus and P. aeruginosa. A comparison of the microbiologic content was made between the solution before and after the cycle. The PuriLens system effectively eradicated S. aureus and P. aeruginosa organisms after a 15-minute cycle. However, viable cysts of acanthamoeba were recovered in the solution after the 15-minute cycle. The PuriLens system is highly efficient in protecting against contamination with common bacterial ocular pathogens. Acanthamoeba cysts, however, can survive in the solution or contact lens bath undergoing integrated subsonic debridement and indirect ultraviolet light disinfection. Use of chemical disinfecting solutions that contain agents such as chlorhexidine or other cationic antiseptics may be advisable in conjunction with use of the PuriLens device, especially in high-risk settings.

Automated virtual colonoscopy

Virtual colonscopy (VC) is a minimally invasive alternative to conventional fiberoptic endoscopy for colorectal cancer screening. The VC technique involves bowel cleansing, gas distension of the colon, spiral computed tomography (CT) scanning of a patient's abdomen and pelvis, and visual analysis of multiplanar 2D and 3D images created from the spiral CT data. Despite the ability of interactive computer graphics to assist a physician in visualizing 3D models of the colon, a correct diagnosis hinges upon a physician's ability to properly identify small and sometimes subtle polyps or masses within hundreds of multiplanar and 3D images. Human visual analysis is time-consuming, tedious, and often prone to error of interpretation.We have addressed the problem of visual analysis by creating a software system that automatically highlights potential lesions in the 2D and 3D images in order to expedite a physician's interpretation of the colon data.

A compilation of generation rates and chemical compositions of potential waste streams in a typical crewed space habitat, reported in a prior NASA Technical Memorandum and a related journal article, was updated. This report augments that compilation by the inclusion of the following new data: those data uncovered since completion of the prior report; those obtained from Soviet literature relevant to life support issues; and those for various minor human body wastes not presented previously (saliva, flatus, hair, finger- and toenails, dried skin and skin secretions, tears, and semen), but included here for purposes of completeness. These waste streams complement those discussed previously: toilet waste (urine, feces, etc.), hygiene water (laundry, shower/handwash, dishwasher water and cleansing agents), trash, humidity condensate, perspiration and respiration water, trace contaminants, and dust generation. This report also reproduces the latest information on the environmental control and life support system design parameters for Space Station Freedom.

In the proposal for this project, we noted how the explosion of digitized information available through corporate databases, data stores and online search systems has resulted in the knowledge worker being bombarded by information. Knowledge workers typically spend more than 20-30% of their time seeking and sorting information, only finding the information 50-60% of the time . This information exists as unstructured, semi-structured and structured data. The problem of information overload is compounded by the production of duplicate or near-duplicate information. In addition, near-duplicate items frequently have different origins, creating a situation in which each item may have unique informationmore » of value, but their differences are not significant enough to justify maintaining them as separate entities. Effective tools can be provided to eliminate duplicate and near-duplicate information. The proposed approach was to extract unique information from data sets and consolidation that information into a single comprehensive file.« less

Periodontal margin in the older adult: considerations for position, placement, and support.

PubMed

McVaney, T P; Ettinger, R L

1991-01-01

Some of the oral health problems of older adults arise from loss of function, which is catalyzed by changes in oral health induced by systemic disease and its treatment. The successful maintenance of a healthy gingival to root surface interface depends on the development of appropriate dental and gingival contours to facilitate self-cleansing and proper hygiene procedures by the patient. This article, with the use of case histories, discusses only one of the complications to restorative care in older adults, that is, loss of function and its relationship to marginal placement. Prevention of oral disease in the older adult may require modification of the long-held periodontal/restorative philosophy of placing margins above the tissue wherever possible. In addition, the professional prophylaxis of restorations adjacent to the gingival margin must address the problems of the creation of a roughened surface by abrasion to composites from pastes and polishing.

Background Currently, there is no standardized protocol for bowel preparation before small bowel capsule endoscopy (SBCE). This study aimed to investigate the effect of simethicone combined with polyethylene glycol (PEG) on the visualization quality (VQ) of the SBCE in patients with or without known or suspected Crohn’s disease (CD). Methods This observational, prospective, single-center study included consecutive patients undergoing a SBCE between 2007 and 2008. Patients received either a standard bowel cleansing preparation of 2 L PEG and 80 mg simethicone orally 12 and 1 h before SBCE respectively (Group A) or only PEG (Group B). VQ, based on scores for luminal bubbles in frames taken from the small intestine, examination completeness, SBCE diagnostic yield, gastric and small bowel transit times were recorded. Results Of the 115 patients finally included (Group A, n=56 and Group B, n=59) the cecum was visualized in 103 (89.6%). Simethicone overall improved the VQ in the proximal [OR: 2.43 (95%CI: 1.08-5.45), P=0.032] but not in the distal bowel segment (P=0.064). Nevertheless, this effect was not observed in patients undergoing SBCE for either known or suspected CD. Conclusion Simethicone as an adjunct to PEG for bowel preparation in patients undergoing SBCE significantly improved the VQ in non-CD patients. PMID:26423317

Scalable, High-performance 3D Imaging Software Platform: System Architecture and Application to Virtual Colonoscopy

Yoshida, Hiroyuki; Wu, Yin; Cai, Wenli; Brett, Bevin

2013-01-01

One of the key challenges in three-dimensional (3D) medical imaging is to enable the fast turn-around time, which is often required for interactive or real-time response. This inevitably requires not only high computational power but also high memory bandwidth due to the massive amount of data that need to be processed. In this work, we have developed a software platform that is designed to support high-performance 3D medical image processing for a wide range of applications using increasingly available and affordable commodity computing systems: multi-core, clusters, and cloud computing systems. To achieve scalable, high-performance computing, our platform (1) employs size-adaptive, distributable block volumes as a core data structure for efficient parallelization of a wide range of 3D image processing algorithms; (2) supports task scheduling for efficient load distribution and balancing; and (3) consists of a layered parallel software libraries that allow a wide range of medical applications to share the same functionalities. We evaluated the performance of our platform by applying it to an electronic cleansing system in virtual colonoscopy, with initial experimental results showing a 10 times performance improvement on an 8-core workstation over the original sequential implementation of the system.

The objective of this study was to compare the sorption and solubility of heat-cure and self-cure acrylic resins in different solutions. One heat-cure acrylic resin (Trevalon) and one self-cure acrylic resin (Rapid Repair) were studied. Five groups of square-shaped specimens (20 mm × 20 mm × 2 mm) were prepared for each acrylic resin and then immersed in five solutions: distilled water, artificial saliva, denture cleansing solution, distilled water, and denture cleaning solution for 12 h alternatively, artificial saliva and denture cleaning solution for 12 h alternatively at 37 ± 2°C, and tested sorption and solubility by weight gain/loss method, respectively, after 1, 6, and 11 weeks. The data were analyzed by one-way analysis of variance followed by post hoc Tukey's test. Water sorption mean values varied from 17.5 ± 0.88 to 27.25 ± 1.04 μg/mm 3 for heat cure and from 12.75 ± 0.55 to 19.75 ± 1.04 μg/mm 3 for self-cure in the different solutions after different interval periods of 1, 6, and 11 weeks. These values were statistically significant (P< 0.001). Water solubility mean values varied from 0.25 ± 0.55 to 1.5 ± 0.55 μg/mm 3 for heat cure and from 1.5 ± 0.55 to 6.5 ± 0.55 μg/mm 3 for self-cure in the different solutions after different interval periods of 1, 6, and 11 weeks. These values were statistically not significant (P > 0.05). There was no linear correlation between sorption and solubility values. Overall, analysis of results showed the maximum sorption value in denture cleansing solution followed by alternative soaking in distilled water and artificial saliva. Least sorption was observed with artificial saliva followed by distilled water. Both heat-cure and self-cure acrylic resins showed varying water sorption and solubility. The results of both water sorption and solubility showed compliance with the International Standards Organization specification. No correlation was found between water sorption and solubility. Artificial saliva solution is a better storage medium than distilled water and denture cleansing solution for both heat-cure and self-cure acrylic resins.

A Detection Pipeline for Galactic Binaries in LISA Data

NASA Technical Reports Server (NTRS)

Littenberg, Tyson B.

2012-01-01

The Galaxy is suspected to contain hundreds of millions of binary white dwarf systems, a large fraction of which will have sufficiently small orbital period to emit gravitational radiation in band for space-based gravitational wave detectors such as the Laser Interferometer Space Antenna (LISA). LISA's main science goal is the detection of cosmological events (supermassive black hole mergers) etc.) however the gravitational signal from the galaxy will be the dominant contribution to the data - including instrumental noise - over approximately two decades in frequency. The catalogue of detectable binary systems will serve as an unparalleled means of studying the Galaxy. Furthermore, to maximize the scientific return from the mission, the data must be "cleansed" of the galactic foreground. We will present an algorithm that can accurately resolve and subtract greater than or equal to 10000 of these sources from simulated data supplied by the Mock LISA Data Challenge Task Force. Using the time evolution of the gravitational wave frequency, we will reconstruct the position of the recovered binaries and show how LISA will sample the entire compact binary population in the Galaxy.

Unravelling nocebo effect: the mediating effect of anxiety between anticipation and pain at wound dressing change.

PubMed

Woo, Kevin Y

2015-07-01

The purpose of this study was to examine the mediating effect of anxiety in the relationship between anticipation and pain in people with chronic wounds. Pain is common in people with chronic wounds. Anticipation or negative expectation of discomfort has been shown to have an augmenting effect on pain; also known as nocebo hyperalgesia. This was a cross-sectional study with repeated measures. Prior to dressing change, anticipatory pain level was evaluated by a 11-point numerical rating scale and anxiety by the Six-items State-Trait Anxiety Inventory (STAI-6). During wound dressing changes, pain was measured before dressing removal, at dressing removal, at cleansing and dressing application using the numerical scale. Analysis was completed based on the data from a convenience sample of 96 patients. Participants reported more pain at cleansing and dressing removal than baseline. High levels of anticipation, anxiety and pain at dressing change for wounds were related to heavy exudate and wound that were covered with necrotic tissue. Finally, the relationship between anticipation and pain perception was mediated by anxiety. Anticipation of pain triggers anxiety that can lead to increased pain. There is a need to incorporate evaluation of anxiety and personal expectations as part of comprehensive pain assessment. Clinicians should be aware of the impact of emotions and anticipation on overall pain experience. © 2015 John Wiley & Sons Ltd.

This descriptive study describes the planning and development of a mobile application (app) for prevention and treatment of pressure injuries for use by providers in a university research center. The app delineates risk factors for pressure injury development, provides an evaluation of the wound, recommends wound cleansing procedures, performs pressure injury staging, and recommends treatment interventions. A mobile app was developed using a contextualized instructional design, which involves a constructivist proposal and planning, developing, and applying specific didactic situations, thus incorporating mechanisms that favor contextualization. A literature search was conducted to identify relevant studies for the construction of the mobile app. The development process involved the selection of app tools, definition of the navigation structure, and planning of the environment configuration. The environment for downloading the app software on the Internet and installing it on the mobile device was created. The literature search yielded 18 articles, 2 books, and 1 master's degree thesis. A mobile app was created with an easy-to-use graphic interface. The app stores the patient's demographic characteristics and provides an evaluation of his/her wound, a list of risk factors for pressure injury development, wound cleansing procedures, and treatment interventions. The developed app may be useful in clinical practice, helping to prevent pressure injuries and promote select nursing interventions for the treatment of patients with pressure injury.

This seminar will provide an overview of structural health monitoring (SHM) research that is being undertaken at Los Alamos National Laboratory (LANL). The seminar will begin by stating that SHM should be viewed as an important component of the more comprehensive intelligent life-cycle engineering process. Then LANL's statistical pattern recognition paradigm for addressing SHM problems will be introduced and current research that is focused on each part of the paradigm will be discussed. In th is paradigm, the process can be broken down into four parts: (1) Operational Evaluation, (2) Data Acquisition and Cleansing, (3) Feature Extraction, and (4) Statisticalmore » Model Development for Feature Discrimination. When one attempts to apply this paradigm to data from real world structures, it quickly becomes apparent that the ability to cleanse, compress, normalize and fuse data to account for operational and environmental variability is a key implementation issue when addressing Parts 2-4 of this paradigm. This discussion will be followed by the introduction a new project entitled 'Intelligent Wind Turbines' which is the focus of much of our current SHM research . This summary will be followed by a discussion of issues that must be addressed if this technology is to make the transition from research to practice and new research directions that are emerging for SHM.« less

How to promote and preserve eyelid health.

PubMed

Benitez-Del-Castillo, Jose M

2012-01-01

Disorders of the lacrimal functional unit are common in ophthalmological practice, with meibomian gland dysfunction, blepharitis, and dry eye forming a significant part of the general ophthalmologist's practice. The eyelid and its associated structures form a complex organ designed to protect the fragile corneal surface and improve visual acuity. This organ is subject to a number of disorders, including meibomian gland dysfunction, dry eye syndrome, anterior blepharitis, allergic and dermatological conditions, and disorders associated with contact lens use. Although commonly described separately, disorders of the lacrimal function unit are better considered as a group of interacting pathologies that have inflammatory mediators as a central feature. Eyelid hygiene, in the sense of routine cleansing and massage of the eyelids, is well accepted in the management of many disorders of the eyelid. However, a broader concept of eyelid health may be appropriate, in which eyelid cleansing is but a part of a more complete program of care that includes screening and risk assessment, patient education, and coaching. The ophthalmologist has an important role to play in helping patients persist with routine eyelid care that may be long-term or lifelong. A number of preparations exist to make routine eyelid care both more effective and more pleasant, and might also improve compliance. Several such preparations have been devised, and are being assessed in clinical studies, and appear to be effective and preferred by patients over traditional soap and water or baby shampoo.

Does modifying personal responsibility moderate the mental contamination effect?

PubMed

Kennedy, Tinisha S; Simonds, Laura M

2017-12-01

Mental contamination is the psychological sense of internal dirtiness that arises in the absence of physical contact with a perceived contaminant. Mental contamination can be evoked through imagining perpetrating a moral transgression. This study experimentally evoked mental contamination by asking men to imagine perpetrating a non-consensual kiss. It explored whether reducing sense of personal responsibility for the kiss moderated the mental contamination effect. Male students (N = 60) imagined giving either a consensual or non-consensual kiss. Personal responsibility for the kiss was manipulated in one of two non-consensual kiss conditions by way of the inclusion of social influence information. Feelings of mental contamination were assessed by self-report and through a behavioural index. Mental contamination was successfully induced in the two non-consensual kiss conditions. There was evidence to support the hypothesis that reducing personal responsibility might moderate specific components of mental contamination (shame, dirtiness and urge to cleanse). The effect of responsibility modification was evident in the self-report measures, but not in the behavioural index. The sample comprised male university students which limits generalizability of the findings. The behavioural assessment of mental contamination was limited to a proxy measure. Imagined moral violations are associated with increases in indices of mental contamination. Further research should investigate whether feelings of shame, dirtiness and urge to cleanse are particularly responsive to responsibility modifications. Copyright © 2017 Elsevier Ltd.

2015-01-01

Significance: Traumatic injuries are the leading cause of morbidity and mortality in children. The purpose of this review is to provide an overview of the initial assessment and management of traumatic and burn wounds in children. Special attention is given to wound cleansing, debridement techniques, and considerations for pain management and psychosocial support for children and families. Recent Advances: Basic and translational research over the last 5–7 years has advanced our knowledge related to the optimal care of acute pediatric traumatic and burn wounds. Data concerning methods, volume, solution and timing for irrigation of acute traumatic wounds, timing and methods of wound debridement, including hydrosurgery and plasma knife coblation, and wound dressings are presented. Additionally, data concerning the long-term psychosocial outcomes following acute injury are presented. Critical Issues: The care of pediatric trauma and burn-related wounds requires prompt assessment, pain control, cleansing, debridement, application of appropriate dressings, and close follow-up. Ideally, a knowledgeable multidisciplinary team cares for these patients. A limitation in the care of these patients is the relative paucity of data specific to the care of acute traumatic wounds in the pediatric population. Future Directions: Research is ongoing in the arenas of new debridement techniques and instruments, and in wound dressing technology. Dedicated research on these topics in the pediatric population will serve to strengthen and advance the care of pediatric patients with acute traumatic and burn wounds. PMID:26487978

Bowel preparation regimens for colon capsule endoscopy are not yet standardized since they are not well optimized. The aim of the present study was to evaluate the feasibility of a novel low-volume and sodium phosphate-free bowel preparation regimen for colon capsule endoscopy. A total of 31 patients were prospectively enrolled. In the novel regimen, on the day prior to examination, a low-fiber diet was permitted, 5 mg mosapride citrate was administered twice (1 h prior to lunch and supper) and 1 l polyethylene glycol was administered in the evening. On the day of the examination, an additional 1 l polyethylene glycol, 5 mg mosapride citrate and 200 mg simethicone were administered before capsule ingestion. Polyethylene glycol booster (0.5 l) was administered twice, at 1 and 4 h following capsule ingestion. Colon cleansing levels, ileocecal valve transit time and completion rate were evaluated. A total of 29 patients were included in the final analysis, 90% of whom achieved adequate preparation of the overall colon. Ileocecal valve transit time was 2.35±0.82 h and completion rate was 79.3%. The results revealed that the novel low-volume and sodium phosphate-free bowel preparation regimen for colon capsule endoscopy was feasible, with adequate colon cleansing and completion rates, and has the potential to be used as an alternative regimen.

Patients with atopic dermatitis (AD) have increased susceptibility to irritants. Some patients have questions about types of water for bathing or skin cleansing. We studied the pH of water from various sources to give an overview for physicians to recommend patients with AD. Water from various sources was collected for measurement of the pH using a pH meter and pH-indicator strips. Bottled drinking still water had pH between 6.9 and 7.5 while the sparkling type had pH between 4.9 and 5.5. Water derived from home water filters had an approximate pH of 7.5 as same as tap water. Swimming pool water had had pH between 7.2 and 7.5 while seawater had a pH of 8. Normal saline and distilled water had pH of 5.4 and 5.7, respectively. Facial mineral water had pH between 7.5 and 8, while facial makeup removing water had an acidic pH. Normal saline, distilled water, bottled sparkling water and facial makeup removing water had similar pH to that of normal skin of normal people. However, other factors including benefits of mineral substances in the water in terms of bacteriostatic and anti-inflammation should be considered in the selection of cleansing water.

What's growing on your stethoscope? (And what you can do about it).

Studies have shown that rubbing alcohol pads on stethoscope diaphragms can reduce bacterial colonization, but alcohol pads are used infrequently used and not always available. We conducted a prospective, single-blinded study to investigate whether simultaneously scrubbing hands and stethoscope head with alcohol-based hand foam would significantly reduce bacterial counts on the stethoscope. Using their own stethoscope, participants imprinted the stethoscope head onto a chocolate agar plate, then used alcohol-based hand foam to cleanse their hands while simultaneously rubbing the stethoscope head. Once the stethoscope heads were dry, the participants imprinted their stethoscope heads onto a second plate. After 48 hours' incubation, we determined the bacterial counts for the prewash and post-wash plates, and compared the 2. We analyzed a total of 184 cultures (from 92 stethoscopes). Both the mean (28 prewash vs 3 post-wash, P=.001) and median (11 prewash vs 1 post-wash, P=.001) colony counts were significantly greater before being cleansed. Three methicillin-resistant Staphylococcus aureus (MRSA) colonies were identified in the prewash period; all were destroyed by the foam. The estimated number of hand washes needed to prevent 1 MRSA colony is 31 (95% confidence interval [CI], 18-89). Simultaneously using hand foam to clean hands and stethoscope heads reduces bacterial counts on stethoscopes. Further research is needed to determine whether this intervention can reduce morbidity and mortality associated with bacterial infection.

The effect of shower/bath frequency on the health and operational effectiveness of soldiers in a field setting: Recommendation of showering frequencies for reducing performance-degrading nonsystemic microbial skin infections

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hall, L.C.; Daniels, J.I.; Aly, R.

Historically, military personnel deployed in the field, particularly in hot, humid environments, have suffered disabling microbial infections of the skin severe enough to contribute to significant reductions in combat-troop strength. Currently, the US Army makes facilities available to field personnel for showering on a weekly basis to prevent infestations of the body louse and the subsequent spread of louse-borne disease. However, a weekly showering frequency has never been evaluated for its efficacy in preventing microbial infections of the skin -- a significant cause of man-days lost from combat in modern-day military conflicts. Consequently, field showers may be more important formore » maintaining combat effectiveness of military personnel than previously thought; however, providing such facilities requires tremendous logistical support. Therefore, we developed shower frequencies for troops in field environments that should minimize or prevent microbial skin infections. According to our calculations, the optimum showering frequency can range from as often as four times per day to as little as once every seven days, depending on skin integrity, environmental conditions, and cleansing agent. We also reviewed the scientific and regulatory information concerning the efficacy and safety of skin-cleansing products; the antimicrobial and antiseptic compounds, triclocarban and chlorhexidine, may be the most suitable for routine use by US military personnel.« less

Methods Water from various sources was collected for measurement of the pH using a pH meter and pH-indicator strips. Results Bottled drinking still water had pH between 6.9 and 7.5 while the sparkling type had pH between 4.9 and 5.5. Water derived from home water filters had an approximate pH of 7.5 as same as tap water. Swimming pool water had had pH between 7.2 and 7.5 while seawater had a pH of 8. Normal saline and distilled water had pH of 5.4 and 5.7, respectively. Facial mineral water had pH between 7.5 and 8, while facial makeup removing water had an acidic pH. Conclusion Normal saline, distilled water, bottled sparkling water and facial makeup removing water had similar pH to that of normal skin of normal people. However, other factors including benefits of mineral substances in the water in terms of bacteriostatic and anti-inflammation should be considered in the selection of cleansing water. PMID:23956962

Realistic estimates of chemical aggregate exposure are needed to ensure consumer safety. As exposure estimates are a critical part of the equation used to calculate acceptable "safe levels" and conduct quantitative risk assessments, methods are needed to produce realistic exposure estimations. To this end, a probabilistic aggregate exposure model was developed to estimate consumer exposure from several rinse off personal cleansing products containing the anti-dandruff preservative zinc pyrithione. The model incorporates large habits and practices surveys, containing data on frequency of use, amount applied, co-use along with market share, and combines these data at the level of the individual based on subject demographics to better estimate exposure. The daily-applied exposure (i.e., amount applied to the skin) was 3.79 mg/kg/day for the 95th percentile consumer. The estimated internal dose for the 95th percentile exposure ranged from 0.01-1.29 μg/kg/day after accounting for retention following rinsing and dermal penetration of ZnPt. This probabilistic aggregate exposure model can be used in the human safety assessment of ingredients in multiple rinse-off technologies (e.g., shampoo, bar soap, body wash, and liquid hand soap). In addition, this model may be used in other situations where refined exposure assessment is required to support a chemical risk assessment. Copyright © 2015 Elsevier Ltd. All rights reserved.

A retrospective analysis of halo device associated morbidity over a 4-year period. To assess the impact of a new pin care regimen on halo pin site related morbidity. Halo orthosis treatment still has a role in cervical spine pathology, despite increasing possibilities of open surgical treatment. Published figures for pin site infection range from 12% to 22% with pin loosening from 7% to 50%. We assessed the outcome of a new pin care regimen on morbidity associated with halo spinal orthoses, using a retrospective cohort study from 2001 to 2004. In the last two years, our pin care regimen was changed. This involved pin site care using chlorhexidene & regular torque checking as part of a standard protocol. Previously, povidone iodine was used as skin preparation in theatre, followed by regular sterile saline cleansing when pin sites became encrusted with blood. There were 37 patients in the series, the median age was 49 (range, 22-83) and 20 patients were male. The overall infection rate prior to the new pin care protocol was 30% (n=6) and after the introduction, it dropped to 5.9% (n=1). This difference was statistically significant (p<0.05). Pin loosening occurred in one patient in the group prior to the formal pin care protocol (3%) and none thereafter. Reduced morbidity from halo use can be achieved with a modified pin cleansing and tightening regimen.

Water for colostomy irrigation is largely absorbed by the colon, which may result in less efficient expulsion of stool. This study compared the outcome of colonic cleansing with water and polyethylene glycol solution. In a cross-over study, 41 colostomy irrigators were randomly assigned to water or polyethylene glycol solution irrigation first and then the other regimen, each for one week. Patients recorded fluid inflow time, total washout time, cramps, leakage episodes, number of stoma pouches used, and satisfaction scores (Visual Analog Scale, 1-10: 1 = poor, and 10 = excellent). The median and interquartile range for each variable was calculated, and the two treatments were compared (Wilcoxon's test). Eight patients failed to complete the study. Thirty-three patients (20 females; mean age, 55 (range, 39-73) years) provided 352 irrigation sessions: water (n = 176), and polyethylene glycol solution (n = 176). Irrigation was performed every 24, 48, and 72 hours by 17, 9, and 7 patients respectively, using 500 ml (n = 1), 750 ml (n = 2), 1,000 ml (n = 16), 1,500 ml (n = 11), 2,000 ml (n = 2), and 3,500 ml (n = 1) of fluid. The median and interquartile range for water vs. polyethylene glycol solution were: fluid inflow time (6 (range, 4.4-10.8) vs. 6.3 (range, 4.1-11) minutes; P = 0.48), total washout time (53 (range, 33-69) vs. 38 (range, 28-55) minutes; P = 0.01), leakage episodes (2.3 (range, 1.7-3.8) vs. 0.7 (range, 0.2-1); P < 0.001), satisfaction score (5.8 (range, 4-7.5) vs. 8.8 (range, 8.3-10); P < 0.001), and stoma pouch usage per week (75 (range, 45-80) vs. 43 (range, 0-80); P = 0.008). No difference was demonstrated for frequency of cramps ( P = 0.24). Polyethylene glycol solution performed significantly better than water and may be a superior alternative fluid regimen for colostomy irrigation.

 Ideal bowel preparation for colonoscopy requires complete removal of fluid and foam from the colon. Polyethylene glycol (PEG) is widely used for bowel preparation, with antifoaming agents such as simethicone commonly used in combination with PEG. Data on the effect of simethicone on the adenoma detection rate (ADR) were limited. This study therefore aimed to investigate whether preprocedure simethicone could increase the ADR.  This was a prospective, multicenter, endoscopist-blinded randomized controlled trial involving consecutive patients who underwent colonoscopy in six centers in China. Patients were randomly assigned to one of two groups: PEG plus simethicone or PEG alone. The primary outcome was ADR; secondary outcomes were quality of bowel preparation, measured by the Boston bowel preparation scale (BBPS) and bubble scores.  583 patients were included. More adenomas were detected in the PEG plus simethicone group than in the PEG alone group (ADR 21.0 % vs. 14.3 %, P  = 0.04; advanced ADR 9.0 % vs. 7.0 %, P  = 0.38). The mean number of adenomas detected was 2.20 ± 1.36 vs. 1.63 ± 0.89 ( P  = 0.02). Patients in the PEG plus simethicone group showed better bowel cleansing efficacy: BBPS ≥ 6 in 88.3 % vs. 75.2 % ( P  < 0.001) and bubble scores of 1.00 ± 1.26 vs. 3.98 ± 2.50 ( P  < 0.001). Abdominal bloating was reported less frequently in the PEG plus simethicone group (7.8 % vs . 19.7 %, P  < 0.001) than in the PEG alone group.  Combined use of PEG and simethicone is associated with a significantly increased ADR in a Chinese population. © Georg Thieme Verlag KG Stuttgart · New York.

AIM: To evaluate the efficacy of same-day bowel preparation with Senna alkaloids combined with bisacodyl tablets in routine colonoscopy procedures. METHODS: Between March and June 2013, a same-day bowel preparation was implemented in our endoscopy unit. The preparation consisted of a semi-liquid, fiber-free diet one day prior to the procedure, with two bisacodyl tablets after lunch and dinner, and 250 mL of Senna alkaloid with 1.5 L of drinking water at 6 am the day of the procedure. The quality control parameters of colonoscopy were evaluated and implemented according to the guidelines of the American Society for Gastrointestinal Endoscopy. The pre-procedure, during-procedure and post-procedure patient data were collected and analyzed: (1) pre-procedure (age, gender, comorbid diseases, colonoscopy indications, complete lack of compliance with the bowel preparation protocol); (2) during-procedure (sedation dose, duration of colonoscopy, withdrawal time, cecal intubation rate, polyp detection rate, Boston Bowel Preparation Scores and presence of foam and clear liquid); and (3) post-procedure (visual analogue scale score, pain during the procedure, patient satisfaction and premature withdrawal due to the insufficient bowel preparation). RESULTS: A total of 75 patients were included in this study with a mean age of 54.64 ± 13.29 years; 53.3% (40/75) were female and 46.7% (35/75) were male. A complete lack of compliance with the bowel preparation protocol was seen in 6.7% of patients (5/75). The mean total duration of colonoscopy was 16.12 ± 6.51 min, and the mean withdrawal time was 8.89 ± 4.07 min. The cecal intubation rate was 93.8% (61/64) and the polyp detection rate was 40% (30/75). The mean Boston Bowel Preparation Score was 7.38 ± 1.81, with the following distribution: right colon, 2.34 ± 0.89; transverse colon, 2.52 ± 0.67; left colon, 2.52 ± 0.63. The mean visual analogue scale score was 4.59 ± 1.57. Due to insufficient bowel preparation, seven patients (7/75; 9.3%) were asked to repeat the procedure. Of these, five patients had poor or modest compliance with the protocol, and two patients reported constipation. Premature withdrawal due to insufficient bowel preparation was 2.7% (2/75). The overall satisfaction with the protocol was 86.7% (65/75), with patients reporting they would prefer the same protocol in a repeat procedure. CONCLUSION: The same-day administration of Senna alkaloids appears to be a safe and effective bowel cleansing protocol for colonoscopy procedures. PMID:25386088

Cardiovascular disease (CVD) is a major issue to public health. It contributes 41% to the Chinese death rate each year. This huge loss encouraged us to develop a Wearable Efficient teleCARdiology systEm (WE-CARE) for early warning and prevention of CVD risks in real time. WE-CARE is expected to work 24/7 online for mobile health (mHealth) applications. Unfortunately, this purpose is often disrupted in system experiments and clinical trials, even if related enabling technologies work properly. This phenomenon is rooted in the overload issue of complex Electrocardiogram (ECG) data in terms of system integration. In this study, our main objective is to get a system light-loading technology to enable mHealth with a benchmarked ECG anomaly recognition rate. To achieve this objective, we propose an approach to purify clinical features from ECG raw data based on manifold learning, called the Manifold-based ECG-feature Purification algorithm. Our clinical trials verify that our proposal can detect anomalies with a recognition rate of up to 94% which is highly valuable in daily public health-risk alert applications based on clinical criteria. Most importantly, the experiment results demonstrate that the WE-CARE system enabled by our proposal can enhance system reliability by at least two times and reduce false negative rates to 0.76%, and extend the battery life by 40.54%, in the system integration level.

Several topical treatments are used in the management of Chronic Rhinosinusitis (CRS), some of which the safety and efficacy has yet to be determined. The purpose of this study was to investigate the effect of commonly used topical treatments on the sinonasal epithelial barrier. Normal saline (0.9% Sodium Chloride), hypertonic saline (3% Sodium Chloride), FESS Sinu-Cleanse Hypertonic, FLO Sinus Care and Budesonide 1 mg/ 2 ml were applied to the apical side of air-liquid interface (ALI) cultures of primary human nasal epithelial cells (HNECs) from CRS patients (n=3) and non-CRS controls (n=3) for 24 hours. Epithelial barrier structure and function was assessed using trans-epithelial electrical resistance (TEER), measuring the passage of Fluorescein Isothiocyanate labelled Dextrans (FITC-Dextrans) and assessing the expression of the tight junction protein Zona Occludens-1 (ZO-1) using immunofluorescence. Toxicity was assessed using a Lactate Dehydrogenase (LDH) assay. Data was analysed using ANOVA, followed by Tukey HSD post hoc test. Hypertonic solution and budesonide significantly increased TEER values in CRS derived HNECs. In contrast, FESS Sinu-Cleanse Hypertonic significantly reduced TEER 5 minutes after application of the solution followed by an increase in paracellular permeability of FITC-Dextrans (30 minutes) and increased LDH levels 6 hours after application of the solution. Our findings confirm that isotonic and hypertonic saline solutions do not compromise epithelial barrier function in vitro but underscore the importance of examining safety and efficacy of over-the-counter wash solutions.

Use of the probiotic Lactobacillus plantarum 299 to reduce pathogenic bacteria in the oropharynx of intubated patients: a randomised controlled open pilot study

Introduction Ventilator-associated pneumonia (VAP) is usually caused by aspiration of pathogenic bacteria from the oropharynx. Oral decontamination with antiseptics, such as chlorhexidine (CHX) or antibiotics, has been used as prophylaxis against this complication. We hypothesised that the probiotic bacteria Lactobacillus plantarum 299 (Lp299) would be as efficient as CHX in reducing the pathogenic bacterial load in the oropharynx of tracheally intubated, mechanically ventilated, critically ill patients. Methods Fifty critically ill patients on mechanical ventilation were randomised to either oral mechanical cleansing followed by washing with 0.1% CHX solution or to the same cleansing procedure followed by oral application of an emulsion of Lp299. Samples for microbiological analyses were taken from the oropharynx and trachea at inclusion and at defined intervals thereafter. Results Potentially pathogenic bacteria that were not present at inclusion were identified in oropharyngeal samples from eight of the patients treated with Lp299 and 13 of those treated with CHX (p = 0.13). Analysis of tracheal samples yielded similar results. Lp299 was recovered from the oropharynx of all patients in the Lp299 group. Conclusions In this pilot study, we found no difference between the effect of Lp299 and CHX used in oral care procedures, when we examined the effects of those agents on colonisation of potentially pathogenic bacteria in the oropharynx of intubated, mechanically ventilated patients.

Opponency of astringent and fat sensations.

In most cultures, people ingest a variety of astringent foods and beverages during meals, but the reasons for this practice are unclear. Many popular beliefs and heuristics, such as high tannin wines should be balanced with fatty foods, for example 'red wine with red meat', suggest that astringents such as pickles, sorbets, wines, and teas 'cleanse' the palate while eating. Oral astringents elicit 'dry, rough' sensations [1], in part, by breaking down mucinous lubricating proteins in saliva [2,3]. The introduction of oral lubricants, including fats, partially diminishes strong astringent sensations [4,5]. Thus, it appears that astringency and fattiness can oppose each other perceptually on an oral rheological spectrum. Most teas, wines, and 'palate cleansers', however, are only mildly astringent and an explanation of how they could oppose the fattiness of meals is lacking. Here, we demonstrate that weakly astringent stimuli can elicit strong sensations after repeated sampling. Astringency builds with exposures [6] to an asymptotic level determined by the structure and concentration of the compound. We also establish that multiple sips of a mild astringent solution, similar to a wine or tea, decrease oral fat sensations elicited by fatty food consumption when astringent and fatty stimuli alternate, mimicking the patterning that occurs during a real meal. Consequently, we reveal a principle underlying the international practice of 'palate cleansing'. Repeatedly alternating samples of astringent beverages with fatty foods yielded ratings of fattiness and astringency that were lower than if rinsing with water or if presented alone without alternation.

Joshi, Saumitra V; Ghosh, Sat

2014-11-21

The detrimental impact of rising air pollution levels in urban landscapes has become conspicuous over the last decade, particularly in developing countries. This novel numerical study quantifies the cleansing efficiency of green façades draped with a copiously growing tropical creeper Vernonia elaeagnifolia. Turbulent transport of SO2 to the leaf boundary layer and subsequent diffusion across stomatal pores into the mesophyllic cells is modeled at the micro level, including its ionic dissociation in the leaf׳s interior. A SEM analysis indicates stomatal dimensions and density. Whilst previous studies have used either spatially averaged equations or resistance models, a spatially discretized computational approach is adopted in this study. The resulting concentration distribution is used to calculate the deposition velocity on stomatal pores, which is then extrapolated over the entire façade to yield bulk pollutant removal rates. A deposition velocity of 1.53mms(-1) and 0.72mms(-1) is obtained for open and closed pores respectively, with removal rates equal to 1.11×10(-6)s(-1) and 1.05×10(-6)s(-1) for dry and humid weather respectively. Sensitivity studies on the removal rate are carried out based on humidity, stomatal aperture and leaf temperature. The removal rate dependence on the Leaf Area Index (LAI) is also investigated. It is inferred from simulations that vegetated façades are efficient at mitigation of residual pollution. Copyright © 2014 Elsevier Ltd. All rights reserved.

Background/Aims: Bile is the main cause of poor bowel preparation for capsule endoscopy (CE). We aimed to determine whether cholestyramine and hydrotalcite can eliminate bile in the bowel. Patients and Methods: Patients undergoing CE were randomized into two groups. Group A patients (n = 75) recieved 250 mL 20% mannitol and 1 L 0.9% saline orally at 20:00 hours on the day before and at 05:00 hours on the day of CE and 20 mL simethicone 30 min before CE. Group B patients (n = 73) were treated identically, except for taking oral cholestyramine and hydrotalcite, starting 3 days before CE. Greenish luminal contents were assessed by four tissue color bar segments using Color Area Statistics software. Bowel cleanliness was evaluated by visualized area percentage assessment of cleansing (AAC) score. Result: Bowel cleanliness (82.7% [62/75] vs 46.6% [34/73]; χ2 = 14.596, P = 0.000). and detected greenish luminal contents (20.0% [15/75] vs 8.2% [6/73]; χ2 = 4.217, P = 0.040) were significantly greater in Group A than in Group B. Greenish luminal contents in the two groups differed significantly in the captured small-bowel (t = −13.74, P = 0.000) segments and proximal small-bowel (t = −0.7365, P = 0.000) segments, but not for the distal small-bowel (t = −0.552, P = 0.581) segments. Conclusions: Cholestyramine and hydrotalcite were ineffective in eliminating bile and improving small-bowel preparation. PMID:26997218

Dizziness and vertigo are the most common complaints of patients that has a high economic burden on the health system. In modern medicine, treatment for dizziness and vertigo consists of chemical pharmacological therapy. Although these drugs are useful in controlling the disease, their side effects and inefficiency in full control of the disease require the use of complementary medicine in this field. Persian medicine consists of valuable experiences of Persian medicine scholars based on the theory of humors and temperaments. In Persian medicine, 2 types of disease are presented: dizziness (sadar) and vertigo (dovar). Persian medicine physicians expressed a different mechanism of action than modern medicine for these diseases. They believed that accumulation of abnormal humors, reeh (normal bloating) or causative pathologic substances, is the basic cause of sadar and dovar and that the most important treatment is cleansing the body, particularly the head from accumulated substances by bloodletting methods.

Background and objective: Chemical cleansing by denture cleansers is first choice for denture plaque control. The most common problems while using denture cleansers are hardening, porosity, odor sorption, water sorption, solubility, and colour change, bacterial and fungal growth. Chemical cleansing procedures have been found to have an effect on the physical and mechanical properties of denture liners. Thus, this study was conducted to evaluate the effect of commercially available denture cleansers on surface hardness and roughness of acrylic and silicon based denture liners at various time interval. Method: Two autopolymerising denture liners Kooliner (acrylic) and GC reline soft (silicon) were tested with two commercially available denture cleansers, polident and efferdent plus. Total of 120 specimens were prepared and all the specimens were divided into six groups based on the relining materials and denture cleansers used. Surface hardness and surface roughness was tested using Shore A durometer and profilometer respectively at the end of day 1, day 7, day 30 and day 90. All the specimens were stored in artificial saliva throughout the study. Cleanser solution was prepared daily by adding Polident and Efferdent plus denture cleanser tablet into 250ml of enough very warm (not hot) water. Acrylic and silicon liner groups were cleansed in a solution of denture cleanser and water for 15 minutes daily, rinsed with water and stored in artificial saliva at room temperature. The data was analyzed with one way ANOVA and independent t-test. Result: The acrylic soft lining showed gradual hardening and increase in surface roughness after immersion in denture cleanser and also with time. Acrylic liner material showed maximum hardness and roughness with Polident followed by Efferdent plus and water (control group). Silicone lining material showed a slight difference in hardness and roughness between the test group and control group. There was a slight increase in hardness in all the groups with time. Very slight increase in mean surface roughness of all the silicon liner groups from day 1 to day 90 was observed. A statistically significant change was noted between and within the all silicon liner groups on day 7, day 30 and day 90. Conclusion: The average surface hardness and surface roughness were lower in silicon liner material than acrylic liner material. Maximum surface roughness was noted by Polident followed by Efferdent Plus and Water for both acrylic liner group and silicon liner group. PMID:28190983

Going through numerous psychological metamorphoses in her lifetime and confronted with numerous challenges, Ksenija Atanasijević developed a specific philosophical-psychological system of consolation prominently featuring the concepts of happiness, bliss, moderation, courage and wisdom. Modifying the original teachings of Democritus and Epicurus, Ksenija Atanasijević developed a distinctive anthropology based on confrontation with but equally the overcoming of obstacles, both internal (spiritual) as well as external ones. The philosopheress developed a reflexive and indeed metaphysical defensive psychotherapeutical skill at the root of which was cleansing the soul, as well as dedication to the realm of fancy, fantasy and imagination. Ksenija Atanasijević also had precious literary talent which was best expressed in her analyses of the poetry and prose of great Serbian writers (Pandurović, Njegos, Nastasijević, etc.). It is quite certain that this, with Anica Savić-Rebac, definitely greatest Serbian philosopheress, through personal suffering, creative solitude and shrouded desperation built an utterly authentic and harmonious system of philosophical comfort.

The hand hygiene technique that the World Health Organization recommends for cleansing hands with soap and water or alcohol-based handrub consists of 7 poses. We used an automated training system to improve clinicians' hand hygiene technique and test whether this affected hospitalwide hand hygiene compliance. Seven hundred eighty-nine medical and nursing staff volunteered to participate in a self-directed training session using the automated training system. The proportion of successful first attempts was reported for each of the 7 poses. Hand hygiene compliance was collected according to the national requirement and rates for 2011-2014 were used to determine the effect of the training system on compliance. The highest pass rate was for pose 1 (palm to palm) at 77% (606 out of 789), whereas pose 6 (clean thumbs) had the lowest pass rate at 27% (216 out of 789). One hundred volunteers provided feedback to 8 items related to satisfaction with the automated training system and most (86%) expressed a high degree of satisfaction and all reported that this method was time-efficient. There was no significant change in compliance rates after the introduction of the automated training system. Observed compliance during the posttraining period declined but increased to 82% in response to other strategies. Technology for training clinicians in the 7 poses played an important education role but did not affect compliance rates. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

The study aims at evaluating the potentials of soaps and germicides/disinfectants as adjunct topical anti-vulvovaginal candidasis agents. In vitro inhibitory activities of the test agents, prepared according to the manufacturer's specification for toilet and midwifery purposes were determined using modified agar well-diffusion method. Varied susceptibility patterns were exhibited by Candida albicans (26.5%), C. glabrata (18.4%), C. pseudotropicalis (14.3%) and C. tropicalis (40.8%) implicated in vulvovaginal candidasis, indicating Crusader oil (100%), Meriko (95%), Tetmosol (84.7%) and Aloe (68.4%) as the most inhibitory soaps against the Candida strains. The in vitro inhibitory activities of the germicides and disinfectants ranged between (Dettol; 34.6% and Purit; 84.6%) for C. albicans; (Roberts; 33.3% and Purit; 83.3%) for C. glabrata; (Roberts; 21.4% and Purit; 92.9%) for C. pseudotropicalis; (Dettol; 35.0% and Purit; 87.5%) for C. tropicalis respectively. All the Candida strains were totally inhibited by the germicides and disinfectants at the second lower dilutions, except in Morigad towards C. albicans (69.2%]) C. glabrata (72.2%), C. pseudotropicalis (92.9%) and C. tropicalis (82.5%) but none of the vaginal Lactobacillus strains was inhibited by the soaps, germicides or disinfectant. About 90% of a control group indicated relief after pubic cleansing with soaps, germicides and disinfectants. Results indicatied the safety of soaps, germicides and disinfectants as potential adjunct topical cleansing-agents in cases of vaginal itching and candidasis, a common mucosal infection caused by opportunistic yeasts of the Candida genus.

To compare between 2 and 4 d colon cleansing protocols. Children who were scheduled for colonoscopy procedure (2010-2012) for various medical reasons, were recruited from the pediatric gastroenterology clinic at Marshall University School of Medicine, Huntington, WV. Exclusion criteria were patients who were allergic to the medication used in the protocols [polyethylene glycol (PEG) 3350, Bisacodyl], or children with metabolic or renal diseases. Two PEG 3350 protocols for 4 d (A) and 2 d (B) were prescribed as previously described. A questionnaire describing the volume of PEG consumed, clinical data, and side effects were recorded. Colon preparation was graded by two observers according to previously described method. Rate of adequate colon preparation. A total of 78 patients were considered for final calculation (group A: 40, group B: 38). Age and stool consistency at the last day was comparable in both groups, but the number of stools/day was significantly higher in group B (P = 0.001). Adequate colon preparation was reached in 57.5% (A) and 73.6% (B), respectively (P = 0.206). Side effects were minimal and comparable in both groups. There was no difference in children's age, stool characteristics, or side effects between the children with adequate or inadequate colon preparation. Correlation and agreement between observers was excellent (Pearson correlation = 0.972, kappa = 1.0). No difference between protocols was observed, but the 2 d protocol was superior for its shorter time. Direct comparison between different colon cleansing protocols is crucial in order to establish the "gold standard" protocol for children.

Scoring systems are used in all diagnostic areas of medicine. Several parameters are evaluated and rated with points according to their value in order to simplify a complex clinical situation with a score. The application ranges from the classification of disease severity through determining the number of staff for the intensive care unit (ICU) to the evaluation of new therapies under study conditions. Since the introduction of scoring systems in the 1980's a variety of different score models has been developed. The scoring systems that are employed in intensive care and are discussed in this article can be categorized into prognostic scores, expenses scores and disease-specific scores. Since the introduction of compulsory recording of two scoring systems for accounting in the German diagnosis-related groups (DRG) system, these tools have gained more importance for all intensive care physicians. Problems remain in the valid calculation of scores and interpretation of the results.

Silver sulfadiazine is commonly used in the treatment of partial-thickness burns, but it sometimes forms pseudo-eschar and delays wound healing. Polyhexanide/betaine gel, a new wound cleansing and moisturizing product, has some advantages in removing biofilm and promotes wound healing. This study was designed to compare clinical efficacy of polyhexanide/betaine gel with silver sulfadiazine in partial-thickness burn treatment. From September 2013 to May 2015, 46 adult patients with partial-thickness burn ≥10% total body surface area that were admitted to the Burn Unit of Siriraj Hospital within 48 hours after injury were randomly allocated into 2 groups. One group was treated with polyhexanide/betaine gel, and the other group was treated with silver sulfadiazine. Both groups received daily dressing changes and the same standard care given to patients with burns in this center. Healing times in the polyhexanide/betaine gel group and silver sulfadiazine group were 17.8 ± 2.2 days and 18.8 ± 2.1 days, respectively ( P value .13). There were no significant differences in healing times, infection rates, bacterial colonization rates, and treatment cost in both groups. The pain score of the polyhexanide/betaine gel group was significantly less than the silver sulfadiazine group at 4 to 9 days after treatment ( P < .001). The satisfactory assessment result of the polyhexanide/betaine gel group was better than that in the silver sulfadiazine group. These data indicate the need for adequately designed studies to elicit the full potential of polyhexanide gel as a wound dressing for partial-thickness burn wounds.

Fecal calprotectin (FC) is the best noninvasive biomarker of disease activity in inflammatory bowel disease. Its correlation with endoscopic mucosal lesions could save inconvenient, expensive, and repeated endoscopic examinations in particular clinical settings. To assess the correlation between FC and the existence and severity of endoscopic postoperative recurrence (POR), a group of clinically stable outpatients with Crohn's disease for whom an ileocolonoscopy was routinely planned to assess POR were invited to collect a stool sample before starting bowel cleansing to measure FC. POR was graded by means of Rutgeerts endoscopic score. One hundred nineteen ileocolonoscopies were included, 42% with endoscopic POR. FC was significantly lower in the absence of endoscopic POR and in the absence of any endoscopic lesion. The area under the receiver operating characteristic curve was 0.76 (95% confidence interval, 0.68-0.85) for the diagnosis of the absence of lesions and 0.75 (95% confidence interval, 0.66-0.84) for endoscopic POR. Better sensitivity and negative predictive value were observed when combining FC and serum C-reactive protein (CRP), leading to a sensitivity of 82%, a specificity of 53%, and negative and positive predictive values of 81% and 54%, respectively, for the prediction of endoscopic POR with a combination of FC 100 μg/g and CRP 5 mg/L cutoff values. FC correlates closely with endoscopic POR in clinically stable postoperative patients with Crohn's disease and, when used in combination with CRP, might save endoscopic examinations and allow for a high-grade suspicion of endoscopic POR in the long-term monitoring of these patients.

The epidemiology and demographic profile of acne vulgaris has evolved over the past several decades, with a noted earlier onset occurring in patients as young as 7 years of age. The combination of a foaming facial wash and a facial moisturizer with a sun protection factor (SPF) of 30 is an over-the-counter cleansing and moisturizing regimen for acne-prone skin that has been shown to be safe and tolerable in subjects 12 years of age and older. To assess the tolerability of this skin care regimen in children ages 7 to 11 years with acne-prone skin. This was an open-label, single-center study that investigated the safety and tolerability of these products in subjects 7 to 11 years of age (ClinicalTrials.gov, NCT01909713). Subjects used the foaming wash twice daily and the SPF 30 moisturizer once daily. Subjects were assessed for cutaneous tolerability, and satisfaction at baseline and weeks 1 and 3. Thirty-five subjects enrolled and completed the study. The cutaneous tolerability score of most subjects was none when assessed by the investigator and subject or legally authorized representative at weeks 1 and 3. The products were well tolerated and a positive impression for cosmetic acceptability was reported for both products by the study population on the questionnaire. This study supports the use of a skin care regimen comprising a wash and a moisturizer in acne-prone patients as young as 7 years old since these products were safe, well tolerated, and liked by subjects. © 2015 Wiley Periodicals, Inc.

Polyethylene glycol (PEG) 3350 is a non-absorbable, non-metabolised osmotic agent used in lavage solutions for gut cleansing. To compare the efficacy of PEG and lactulose in chronic constipation. A total of 115 patients with chronic constipation entered a multicentre, randomised, comparative trial. They initially received two sachets containing either PEG (13 g/sachet) or lactulose (10 g/sachet) and were given an option to change the dose to one or three sachets/day, depending on response. Ninety nine patients completed the trial. After four weeks, patients in the PEG group (n=50) had a higher number of stools and a lower median daily score for straining at stool than patients in the lactulose group (n=49). Overall improvement was greater in the PEG group. Clinical tolerance was similar in the two groups, but flatus was less frequently reported in the PEG group. The mean number of liquid stools was higher in the PEG group but the difference was significant only for the first two weeks. There were no serious adverse events and no significant change in laboratory tests in either group. At the end of the study, the number of sachets used by the patients was 1.6 (0.7)/day in the PEG group and 2.1 (0.7)/day in the lactulose group. Sixty one patients completed a further two months open study of one to three sachets PEG daily; there was no loss of efficacy and no serious toxicity. Low dose PEG 3350 was more effective than lactulose and better tolerated.

Pressure ulcer assessment and management.

PubMed

Ratliff, C R; Rodeheaver, G T

1999-01-01

A pressure ulcer is an area of localized tissue destruction directly related to prolonged pressure. The loss of skin integrity produces significant consequences not only for the individual, but also for the community, with reported costs of $8.5 billion for pressure-ulcer care. Because of these costs, health care providers should be seeking prevention programs that identify high-risk individuals and implement preventive measures before the ulcer begins. Once the individual develops an ulcer, assessment of healing is critical to determine the appropriate treatment. Successful treatment depends on the principles of debridement, cleansing, bacterial control, wound dressing, and occasionally, surgical intervention.

Root canal treatment is still a problem in dentistry. Very often the conventional treatment fails and several treatment sessions are necessary to save the tooth from root resection or extraction. Application of lasers may help in this situation. Bacteria reduction has been demonstrated both in vitro and clinically and is either based on laser induced thermal effects or by using an ultraviolet light source. Root canal cleansing is possible by Er:YAG/YSGG-Lasers, using the hydrodynamic motion of a fluid filled in the canals. However root canal shaping using lasers is still a problem. Via falsas and fiber breakage are points of research.

Therapeutic colonoscopy with electrocautery is widely used around the world. Adequate colonic cleansing is considered a crucial factor for the safety of this procedure. Colonic gas explosion, although rare, is one of the most frightening iatrogenic complications during colonoscopy with electrocautery. This complication is the result of an accumulation of colonic gases to explosive concentrations, but may be prevented by meticulous bowel preparation. The purpose of this review is to discuss the indications and the types of bowel preparations for therapeutic colonoscopy, and to contribute recommendations for the adequate bowel preparation for colonoscopy with electrocautery.

Incomplete understanding of menstruation may place girls at risk for sexually transmitted diseases (STDs) and unintended pregnancy. Prior research suggests that European American and African American girls incompletely understand menstruation, yet little is known about menstrual knowledge in other ethnic groups. Using audiotaped focus group and individual interviews with 73 African American, Mexican American, Arab American, and European American girls, we assessed girls' menstrual understanding. Responses included reproduction, growing up, cleansing, messages about femininity, and not knowing. We found ethnic differences in the prominence of these themes. We learned that social and cultural factors play an important role in transmission of menstrual knowledge.

2011-08-01

The provision of the patient bed-bath is a fundamental nursing care activity yet few quantitative data and no qualitative data are available on registered nurses' (RNs) clinical practice in this domain in the intensive care unit (ICU). The aim of this study was to describe ICU RNs current practice with respect to the timing, frequency and duration of the patient bed-bath and the cleansing and emollient agents used. The study utilised a two-phase sequential explanatory mixed method design. Phase one used a questionnaire to survey RNs and phase two employed semi-structured focus group (FG) interviews with RNs. Data was collected over 28 days across four Australian metropolitan ICUs. Ethical approval was granted from the relevant hospital and university human research ethics committees. RNs were asked to complete a questionnaire following each episode of care (i.e. bed-bath) and then to attend one of three FG interviews: RNs with less than 2 years ICU experience; RNs with 2-5 years ICU experience; and RNs with greater than 5 years ICU experience. During the 28-day study period the four ICUs had 77.25 beds open. In phase one a total of 539 questionnaires were returned, representing 30.5% of episodes of patient bed-baths (based on 1767 bed occupancy and one bed-bath per patient per day). In 349 bed-bath episodes 54.7% patients were mechanically ventilated. The bed-bath was given between 02.00 and 06.00h in 161 episodes (30%), took 15-30min to complete (n=195, 36.2%) and was completed within the last 8h in 304 episodes (56.8%). Cleansing agents used were predominantly pH balanced soap or liquid soap and water (n=379, 71%) in comparison to chlorhexidine impregnated sponges/cloths (n=86, 16.1%) or other agents such as pre-packaged washcloths (n=65, 12.2%). In 347 episodes (64.4%) emollients were not applied after the bed-bath. In phase two 12 FGs were conducted (three FGs at each ICU) with a total of 42 RN participants. Thematic analysis of FG transcripts across the three levels of RN ICU experience highlighted a transition of patient hygiene practice philosophy from shades of grey - falling in line for inexperienced clinicians to experienced clinicians concrete beliefs about patient bed-bath needs. This study identified variation in process and products used in patient hygiene practices in four ICUs. Further study to improve patient outcomes is required to determine the appropriate timing of patient hygiene activities and cleansing agents used to improve skin integrity.

Dog bite wounds represent a major health problem. Despite their importance, their management and especially the role of primary closure remain controversial. In this randomised controlled trial, the outcome between primary suturing and non-closure was compared. 168 consecutive patients with dog bite injuries were included in this study. The wounds were allocated randomly in two treatment approaches: Group 1, consisting of eighty-two patients, had their wound sutured, whilst Group 2, consisting of eighty-six patients, did not have their wounds sutured. All wounds were cleansed using high-pressure irrigation and povidone iodine. All patients received the same type of antibiotic treatment. Our measured outcomes included presence of infection and cosmetic appearance. Cosmetic outcome was evaluated using the Vancouver Scar Scale (VSS). Wound and patient characteristics, such as time of management, wound location and size, and patient age, were recorded and analysed for their potential role in the resulting outcome. The overall infection rate was 8.3%. No difference in the infection rate between primary suturing and non-suturing group was detected in the present study. The cosmetic appearance of the sutured wounds was significantly better (mean score 1.74) compared to the wounds that were left open (mean score 3.05) (p=0.0001). The infection rate was comparable among all age groups. Wounds treated within 8h of injury demonstrated an infection rate of 4.5%, which is lower compared to the 22.2% rate observed in wounds treated later than 8h. The wounds located at the head and neck exhibited better results in both infection rate and cosmetic outcome. Additionally, wounds >3 cm negatively affected the cosmetic appearance of the outcome. Primary suturing of wounds caused by dog bites resulted in similar infection rate compared to non-suturing. However, primary suturing exhibited improved cosmetic appearance. Time of management appeared to be critical, as early treatment resulted in lower infection rate and improved cosmetic appearance regardless suturing or not. Furthermore, wounds located at the head and face demonstrated better results. Copyright © 2013 Elsevier Ltd. All rights reserved.

No bowel preparation for colonoscopy is optimal with regard to efficacy, safety, and tolerability. New options for bowel preparation are needed. To compare a new hybrid preparation consisting of a reduced dose of oral sulfate solution (OSS) plus 2 L of sulfate-free electrolyte lavage solution (SF-ELS) with 2 low-volume preparations based on polyethylene glycol electrolyte lavage solution (PEG-ELS). Two randomized, controlled trials. Twenty-four U.S. centers. A total of 737 outpatients undergoing colonoscopy. In study 1, OSS plus SF-ELS was given as a split dose, and in study 2, OSS plus SF-ELS was given in its entirety the evening before colonoscopy. In study 1, the active control was 2 L of PEG-ELS plus ascorbic acid (PEG-EA) given as a split dose. In study 2, the control was 10 mg of bisacodyl plus 2 L of SF-ELS taken the evening before colonoscopy. Rates of successful (good or excellent) bowel preparation. In study 1, the rates of successful (excellent or good) preparation with OSS plus SF-ELS and PEG-EA were identical at 93.5% for split-dose preparation. OSS plus SF-ELS was noninferior to PEG-EA (P < .001). In study 2, OSS plus SF-ELS resulted in successful preparation in 89.8% of patients compared with 83.5% with bisacodyl plus SF-ELS in a same-day preparation regimen. OSS plus SF-ELS was noninferior to bisacodyl plus SF-ELS (P <.001). In study 1, vomiting was more frequent with OSS plus SF-ELS (13.5% vs 6.7%; P = .042), and bloating was rated worse with PEG-EA (P = .025). In study 2, overall discomfort was rated worse with OSS plus SF-ELS (mean score 2.1 vs 1.8; P = .032). There were no deaths in either study and no serious adverse events considered related to the preparation. Bowel cleansing was not scored by colon segment. Adenoma detection was not compared between the regimens. OSS plus SF-ELS is a new, safe, and effective bowel preparation for colonoscopy.

Acute appendicitis is the most common surgical condition presented in emergency departments worldwide. Clinical scoring systems, such as the Alvarado and modified Alvarado scoring systems, were developed with the goal of reducing the negative appendectomy rate to 5%-10%. The Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) scoring system was established in 2008 specifically for Asian populations. The aim of this study was to compare the modified Alvarado with the RIPASA scoring system in Kuwait population. This study included 180 patients who underwent appendectomies and were documented as having "acute appendicitis" or "abdominal pain" in the operating theatre logbook (unit B) from November 2014 to March 2016. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), diagnostic accuracy, predicted negative appendectomy and receiver operating characteristic (ROC) curve of the modified Alvarado and RIPASA scoring systems were derived using SPSS statistical software. A total of 136 patients were included in this study according to our criteria. The cut-off threshold point of the modified Alvarado score was set at 7.0, which yielded a sensitivity of 82.8% and a specificity of 56%. The PPV was 89.3% and the NPV was 42.4%. The cut-off threshold point of the RIPASA score was set at 7.5, which yielded a 94.5% sensitivity and an 88% specificity. The PPV was 97.2% and the NPV was 78.5%. The predicted negative appendectomy rates were 10.7% and 2.2% for the modified Alvarado and RIPASA scoring systems, respectively. The negative appendectomy rate decreased significantly, from 18.4% to 10.7% for the modified Alvarado, and to 2.2% for the RIPASA scoring system, which was a significant difference (P<0.001) for both scoring systems. Based on the results of this study, the RIPASA score is a simple scoring system with better sensitivity and specificity than the modified Alvarado scoring system in Asian populations. It consists of 14 clinical parameters that can be obtained from a good patient history, clinical examination and laboratory investigations. The RIPASA scoring system is more accurate and specific than the modified Alvarado scoring system for Kuwait population.

The aims of this study were to compare various genotypic scoring systems commonly used to predict virological outcome to etravirine, and examine their concordance with etravirine phenotypic susceptibility. Six etravirine genotypic scoring systems were assessed: Tibotec 2010 (based on 20 mutations; TBT 20), Monogram, Stanford HIVdb, ANRS, Rega (based on 37, 30, 27 and 49 mutations, respectively) and virco(®)TYPE HIV-1 (predicted fold change based on genotype). Samples from treatment-experienced patients who participated in the DUET trials and with both genotypic and phenotypic data (n=403) were assessed using each scoring system. Results were retrospectively correlated with virological response in DUET. κ coefficients were calculated to estimate the degree of correlation between the different scoring systems. Correlation between the five scoring systems and the TBT 20 system was approximately 90%. Virological response by etravirine susceptibility was comparable regardless of which scoring system was utilized, with 70-74% of DUET patients determined as susceptible to etravirine by the different scoring systems achieving plasma viral load <50 HIV-1 RNA copies/ml. In samples classed as phenotypically susceptible to etravirine (fold change in 50% effective concentration ≤3), correlations with genotypic score were consistently high across scoring systems (≥70%). In general, the etravirine genotypic scoring systems produced similar results, and genotype-phenotype concordance was high. As such, phenotypic interpretations, and in their absence all genotypic scoring systems investigated, may be used to reliably predict the activity of etravirine.

The rat whole embryo culture (WEC) system has been used extensively for characterizing teratogenic properties of test chemicals. In this chapter, we describe the methodology for culturing rat embryos as well as a new morphological score system, the Dysmorphology Score (DMS) system for assessing morphology of mid gestation (gestational day 11) rat embryos. In contrast to the developmental stage focused scoring associated with the Brown and Fabro score system, this new score system assesses the respective degree of severity of dysmorphology, which delineates normal from abnormal morphology of specific embryonic structures and organ systems. This score system generates an approach that allows rapid identification and quantification of adverse developmental findings, making it conducive for characterization of compounds for teratogenic properties and screening activities.

Mammalian short palate lung and nasal epithelial clone 1 (SPLUNC1) in pH-dependent airway hydration✩

PubMed Central

Tarran, Robert; Redinbo, Matthew R.

2014-01-01

The epithelia that line the conducting airways are the lung’s first point of contact with inhaled pathogens and toxicants. As such, they are known to play an important role in the lung’s innate defense system, which includes (i) the production of airway surface liquid (ASL) that helps cleanse the airways through the physical removal of pathogens and toxicants on the mucociliary escalator and (ii) the secretion of anti-microbial proteins into the ASL to kill inhaled pathogens. Interestingly, the recently crystallized short palate lung and nasal epithelial clone 1 (SPLUNC1) protein appears to be a multi-functional protein. That is, it not only acts as an anti-microbial agent, but also modulates ASL homeostasis by acting as an endogenous inhibitor of the epithelial Na+ channel (ENaC). This review will focus on the latter function of SPLUNC1, and will discuss new structural and physiological data regarding SPLUNC1’s failure to function as a regulator of ASL hydration in CF airways.

Treatment-induced mucositis: an old problem with new remedies.

PubMed

Symonds, R P

1998-05-01

Mucositis may be a painful, debilitating, dose-limiting side-effect of both chemotherapy and radiotherapy for which there is no widely accepted prophylaxis or effective treatment. The basis of management is pain relief, prevention of dehydration and adequate nutrition. When tested vigorously, most antiseptic mouthwashes and anti-ulcer agents are ineffective. Simple mechanical cleansing by saline is the most effective traditional measure. A variety of new agents are effective. Granulocyte macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) act outwith the haemopoeitic system and can reduce mucositis, but the best schedule, dosage and method of administration is not known or which is the best growth factor to prevent this side-effect. A placebo-controlled randomized trial of antibiotic pastilles has shown a significant reduction in mucositis and weight loss during radiotherapy for head and neck cancer. Another method to reduce radiation effects in normal tissue is to stimulate cells to divide before radiotherapy by silver nitrate or interleukin 1. These methods may be particularly effective when given along with hyperfractionated radiation treatment such as CHART.

Muriatic acid (hydrochloric acid), a common cleaning and resurfacing agent for concrete pools, can cause significant burn injuries. When coating a pool with chlorinated rubber-based paint, the pool surface is initially cleansed using 31.45% muriatic acid. Here we report a 50-year-old Hispanic male pool worker who, during the process of a pool resurfacing, experienced significant contact exposure to a combination of muriatic acid and blue chlorinated rubber-based paint. Confounding the clinical situation was the inability to efficiently remove the chemical secondary to the rubber-based nature of the paint. Additionally, vigorous attempts were made to remove the rubber paint using a variety of agents, including bacitracin, chlorhexidine soap, GOOP adhesive, and Johnson's baby oil. Resultant injuries were devastating fourth-degree burns requiring an immediate operative excision and amputation. Despite aggressive operative intervention and resuscitation, he continued to have severe metabolic derangements and ultimately succumbed to his injuries. We present our attempts at debridement and the system in place to manage patients with complex chemical burns.

Patients with perforated peptic ulcer (PPU) often present with acute, severe illness that carries a high risk for morbidity and mortality. Mortality ranges from 3-40% and several prognostic scoring systems have been suggested. The aim of this study was to review the available scoring systems for PPU patients, and to assert if there is evidence to prefer one to the other. We searched PubMed for the mesh terms "perforated peptic ulcer", "scoring systems", "risk factors", "outcome prediction", "mortality", "morbidity" and the combinations of these terms. In addition to relevant scores introduced in the past (e.g. Boey score), we included recent studies published between January 2000 and December 2012) that reported on scoring systems for prediction of morbidity and mortality in PPU patients. A total of ten different scoring systems used to predict outcome in PPU patients were identified; the Boey score, the Hacettepe score, the Jabalpur score the peptic ulcer perforation (PULP) score, the ASA score, the Charlson comorbidity index, the sepsis score, the Mannheim Peritonitis Index (MPI), the Acute physiology and chronic health evaluation II (APACHE II), the simplified acute physiology score II (SAPS II), the Mortality probability models II (MPM II), the Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity physical sub-score (POSSUM-phys score). Only four of the scores were specifically constructed for PPU patients. In five studies the accuracy of outcome prediction of different scoring systems was evaluated by receiver operating characteristics curve (ROC) analysis, and the corresponding area under the curve (AUC) among studies compared. Considerable variation in performance both between different scores and between different studies was found, with the lowest and highest AUC reported between 0.63 and 0.98, respectively. While the Boey score and the ASA score are most commonly used to predict outcome for PPU patients, considerable variations in accuracy for outcome prediction were shown. Other scoring systems are hampered by a lack of validation or by their complexity that precludes routine clinical use. While the PULP score seems promising it needs external validation before widespread use.

In most low- and middle-income countries (LMICs), the resources to accurately quantify injury severity using traditional injury scoring systems are limited. Novel injury scoring systems appear to have adequate discrimination for mortality in LMIC contexts, but they have not been rigorously compared where traditional injury scores can be accurately calculated. To determine whether novel injury scoring systems perform as well as traditional ones in a HIC with complete and comprehensive data collection. Data from an American level-I trauma registry collected 2008-2013 were used to compare three traditional injury scoring systems: Injury Severity Score (ISS); Revised Trauma Score (RTS); and Trauma Injury Severity Score (TRISS); and three novel injury scoring systems: Kampala Trauma Score (KTS); Mechanism, GCS, Age and Pressure (MGAP) score; and GCS, Age and Pressure (GAP) score. Logistic regression was used to assess the association between each scoring system and mortality. Standardized regression coefficients (β 2 ), Akaike information criteria, area under the receiver operating characteristics curve, and the calibration line intercept and slope were used to evaluate the discrimination and calibration of each model. Among 18,746 patients, all six scores were associated with hospital mortality. GAP had the highest effect size, and KTS had the lowest median Akaike information criteria. Although TRISS discriminated best, the discrimination of KTS approached that of TRISS and outperformed GAP, MGAP, RTS, and ISS. MGAP was best calibrated, and KTS was better calibrated than RTS, GAP, ISS, or TRISS. The novel injury scoring systems (KTS, MGAP, and GAP), which are more feasible to calculate in low-resource settings, discriminated hospital mortality as well as traditional injury scoring systems (ISS and RTS) and approached the discrimination of a sophisticated, data-intensive injury scoring system (TRISS) in a high-resource setting. Two novel injury scoring systems (KTS and MGAP) surpassed the calibration of TRISS. These novel injury scoring systems should be considered when clinicians and researchers wish to accurately account for injury severity. Implementation of these resource-appropriate tools in LMICs can improve injury surveillance, guiding quality improvement efforts, and supporting advocacy for resource allocation commensurate with the volume and severity of trauma.

A stage is a stage is a stage: a direct comparison of two scoring systems.

Dawson, Theo L

L. Kohlberg (1969) argued that his moral stages captured a developmental sequence specific to the moral domain. To explore that contention, the author compared stage assignments obtained with the Standard Issue Scoring System (A. Colby & L. Kohlberg, 1987a, 1987b) and those obtained with a generalized content-independent stage-scoring system called the Hierarchical Complexity Scoring System (T. L. Dawson, 2002a), on 637 moral judgment interviews (participants' ages ranged from 5 to 86 years). The correlation between stage scores produced with the 2 systems was .88. Although standard issue scoring and hierarchical complexity scoring often awarded different scores up to Kohlberg's Moral Stage 2/3, from his Moral Stage 3 onward, scores awarded with the two systems predominantly agreed. The author explores the implications for developmental research.

Improvement of the Mair scoring system using structural equations modeling for classifying the diagnostic adequacy of cytology material from thyroid lesions.

The scoring system developed by Mair et al. (Acta Cytol 1989;33:809-813) is frequently used to grade the quality of cytology smears. Using a one-factor analytic structural equations model, we demonstrate that the errors in measurement of the parameters used in the Mair scoring system are highly and significantly correlated. We recommend the use of either a multiplicative scoring system, using linear scores, or an additive scoring system, using exponential scores, to correct for the correlated errors. We suggest that the 0, 1, and 2 points used in the Mair scoring system be replaced by 1, 2, and 4, respectively. Using data on fine-needle biopsies of 200 thyroid lesions by both fine-needle aspiration (FNA) and fine-needle capillary sampling (FNC), we demonstrate that our modification of the Mair scoring system is more sensitive and more consistent with the structural equations model. Therefore, we recommend that the modified Mair scoring system be used for classifying the diagnostic adequacy of cytology smears. Diagn. Cytopathol. 1999;21:387-393. Copyright 1999 Wiley-Liss, Inc.

We present preliminary results obtained from a spatio-temporal analysis of mountain worship directions at the Atacama Indian community of Socaire, northern Chile (23°35'28''S, 67°52'36''W, 3,274 masl). These results can be linked to cultural, geographical, climatic, psychological and astronomical information from ethno-archaeological data. We propose a"system of offering to mountains" that includes concepts such as ceque (straight line), mayllku or mallku (mountain lord or ancestor), and pacha (space and time), which is understood as the projection of a left human hand in the visible horizon (Tumisa, Lausa, Chiliques, Ipira and Miñiques Mountains) (PAH-Triad). This system regulates annual activities such as planting (August 1st), harvesting (May 1st), cleansing of irrigation channels (October 24-26th), and the Catholic rituals and festivities of Saint Bartholomew (August 24th), Saint Barbara (December 4th), Christmas-Summer solstice (December 25th), Carnival (between February and March), Holy Cross (May 3rd), and Saint John-Winter solstice (June 24th). More importantly: it gives a basis for Socaireños' worldview including categories of"above, here, and down";"right and left";"female and male";"noon and midnight";"north and south";"visible and non-visible", along with the Andean concepts of center (ushnu);"two, three, four and five division"; and"humanized landscape".

Use of antibiotics in the management of postirradiation wound infection and sepsis

Brook, I.

1988-07-01

Ionizing gamma irradiation depresses the host defenses and enhances the susceptibility of the immunocompromised host to local and systemic infection due to endogenous or exogenous microorganisms. Trauma and wounding act synergistically and decrease the survival after exposure to irradiation. The current antimicrobial agents suitable for controlling serious infections and their use in post irradiation local and systemic infection with and without trauma are discussed. The experience gained in managing immunocompromised patients following chemotherapy is reviewed. Empiric single agent or combination agent therapy should be directed at the eradication of potential gram-negative as well as gram-positive pathogens. The most important organismsmore » known to cause these infections are Pseudomonas sp. and Enterobacteriaceae. Management of intra-abdominal infections following trauma should include early surgical correlation and antimicrobials directed against the Bacteroides fragilis group and Enterobacteriaceae. Staphylococcus aureus and Streptococcus pyogenes cause most skin and soft tissue infections following trauma. Chemoprophylaxis of enteric sources of systemic infection can be achieved by antimicrobials that selectively inhibit the Enterobacteriaceae sp. and preserve the anaerobic flora. The management of infection in the injured and irradiated host includes supportive and restorative therapy. Supportive therapy includes debridement and cleansing of wounds, fluids, immunoglobulin, and antimicrobials. Restorative therapy includes definite surgery repair and replenishment of the immune system by use of immunomodulators, growth factors, and bone marrow transplantation. Further studies are needed to examine the usefulness of presently available drugs and experimental agents in the irradiated and traumatized host. 111 references.« less

Objective: To investigate the feasibility of laxative-free bowel preparation to relieve the patient stress in colon cleansing for virtual colonoscopy. Materials and Methods: Three different bowel-preparation protocols were investigated by 60 study cases from 35 healthy male volunteers. All the protocols utilize low-residue diet for two days and differ in diet for the third day - the day just prior to image acquisition in the fourth day morning. Protocol Diet-1 utilizes fluid or liquid diet in the third day, Diet-2 utilizes a food kit, and Diet-3 remains the low-residue diet. Oral contrast of barium sulfate (2.1%, 250 ml) was added respectively to the dinner in the second day and the three meals in the third day. Two doses of MD-Gastroview (60 ml) were ingested each in the evening of the third day and in the morning before image acquisition. Images were acquired by a single-slice detector spiral CT (computed tomography) scanner with 5 mm collimation, 1 mm reconstruction, 1.5-2.0:1.0 pitch, 100-150 mA, and 120 kVp after the colons were inflated by CO2. The contrasted colonic residue materials were electronically removed from the CT images by specialized computer-segmentation algorithms. Results: By assumptions that the healthy young volunteers have no polyp and the image resolution is approximately 4 mm, a successful electronic cleansing is defined as "no more than five false positives and no removal of a colon fold part greater than 4 mm" for each study case. The successful rate is 100% for protocol Diet-1, 77% for Diet-2 and 57% for Diet-3. Conclusion: A laxative-free bowel preparation is feasible for virtual colonoscopy.

Background A split-dose (SD) regimen is crucial for colonoscopy quality. Compliance with SD for early morning colonoscopy is generally poor. The present study evaluated whether pre-colonoscopy counselling, in addition to a dedicated leaflet, might increase SD uptake. Methods Consecutive 50–69-year-old patients undergoing screening colonoscopy before 10 a.m. were randomized to either receive written information only on bowel preparation (Written Group, WG) or written and oral instructions (Written and Oral Group, WaOG). The leaflet strongly encouraged SD adoption. The primary endpoint was the number of patients adopting SD in each group. The secondary endpoints were predictors of SD uptake, compliance with preparation schemes and cleansing adequacy. Results A total of 286 patients (143 WG, 143 WaOG) were enrolled (mean age 59.6 ± 6.1 years, men 49.3%). SD was adopted by 114 and 125 patients in the WG and WaOG, respectively (79.7% versus 87.4%, p = 0.079). No significant differences were observed for the proportion of patients with full compliance with preparation scheme (97.9% versus 97.2%, p = 0.99) and of procedures with adequate bowel cleansing (95.6% versus 95.1%, p = 0.77). At multivariate analysis, a > 1 h travel time to the endoscopy service was inversely correlated with SD uptake (odds ratio (OR) 0.30, 95% confidence interval (CI) 0.09–0.98). Conclusions Our leaflet guaranteed satisfactory uptake of SD and excellent adherence to the preparation scheme for early morning colonoscopy. Its use might marginalize the need for additional oral instructions, particularly in open-access settings. PMID:29511558

Colonic bubbles associated with polyethylene glycol-electrolyte solution (PEG-ELS) are common and obscure mucosal visualization. This study aimed to determine whether adding simethicone decreases the incidence of bubbles. Prospective, single-blind, randomized comparison of split dose PEG-ELS vs. PEG-ELS+simethicone (PEG-S) for outpatient colonoscopy. Bubble severity for colonic segments was assessed on withdrawal as A=no/minimal bubbles, B=moderate bubbles/interfere with detecting 5 mm polyp, C=severe bubbles/interfere with detecting 10 mm polyp. Primary end point was Grade B or C bubbles in any colon segment. Secondary end points were cleansing quality, incidence and severity of side effects, and polyp detection. One hundred and thirty nine patients enrolled; 13 withdrew before colonoscopy. Of 123 patients evaluated, 62 took PEG-S and 61 PEG-ELS. The incidence of grade B or C bubbles was much lower with PEG-S compared with PEG-ELS (2% vs. 38%; P=0.001). Overall cleansing (excellent or good) quality was not significantly different for either the whole colon (89% PEG-ELS, 94% of PEG-S, P=0.529) or right colon (88% PEG-ELS, 94% PEG-S, P=0.365). More PEG-S patients had excellent rather than good preps (whole colon 53% vs. 28%, P=0.004; right colon 53% vs. 35%, P=0.044). Need for any flushing was less with PEG-S (38% vs. 70%, P=0.001). The groups were not significantly different with respect to total procedure and withdrawal times, incidence or severity of side effects, or number of polyps/patient or adenomas/patient. Adding simethicone to PEG-ELS effectively eliminates bubbles, substantially reduces the need for flushing, and results in more excellent preparations.

Foodborne pathogens, such as Salmonella, may remain in abattoir lairages after cleansing and pose a risk of transfer and contamination from one processing day to the next. These organisms may be transferred to the outer surface of animals held in lairage facilities, and the skin or hide may be a significant source of microbial contamination on the red meat carcasses subsequently produced. Sponge samples were taken from various sites in the lairage (n = 556), and single-pass sponge samples were taken from one side of red meat carcasses (n = 1,050) at five commercial abattoirs in Southwest England and tested for the presence of Salmonella. Of these, 6.5% of lairage samples were positive, containing estimated numbers of up to 10(4) Salmonella organisms per sampled area (50 by 50 cm). Salmonella was found on 9.6% of 240 lamb carcasses, 12.7% of 330 beef carcasses, 31% of 70 pig carcasses, 20% of 80 calf carcasses younger than 14 days of age, and none of 330 cull cow and bull carcasses. Subtyping divided the 137 isolates into seven serogroups and three pulsed-field gel electrophoresis clusters, and sensitivity testing against a bank of 16 antimicrobials indicated that 47 isolates had resistance to one or more antimicrobial agents. These results indicate that Salmonella contamination can persist in the lairage environment from one processing day to the next and that Salmonella is present on red meat carcasses, although the implications of residual lairage contamination on carcass meat microbiology are not clear from this study. Abattoir owners should take steps to reduce the level of contamination in their premises to prevent contamination from being carried over from one processing day to the next.

This study was aimed to evaluate the efficacy and safety of two low-volume agents, polyethylene glycol (PEG)-3350 plus ascorbic acid (PEG + Asc) and sodium picosulfate with magnesium citrate (SPMC), for bowel preparation. We performed a prospective, endoscopist-blinded, single-center, randomized controlled trial comparing PEG + Asc with SPMC to evaluate the bowel cleansing efficacy of the two regimens using the modified Ottawa bowel preparation scale (OBPS) and the Aronchick scale. Patients' taste and overall tolerance were assessed with a questionnaire. In total, 200 patients were randomized to receive either PEG + Asc (n = 98) or SPMC (n = 102). Both treatments were similarly efficacious in bowel cleansing, based on the modified OBSP (PEG + Asc 4.01 ± 2.29 vs SPMC 3.86 ± 2.47, P = 0.62) and Aronchick scale (PEG + Asc 1.96 ± 0.70 vs SPMC 1.89 ± 0.70, P = 0.42). Patient-reported taste and tolerance of each regimen, as reported by the questionnaire, were significantly greater in the PEG + Asc group than in the SPMC group (P = 0.01). In terms of adverse events, dizziness was more frequently observed in the PEG + Asc group (P = 0.03), whereas nausea was more common in the SPMC group (P = 0.02). PEG + Asc and SPMC show similar efficacy for bowel preparation. However, patient's overall tolerance is higher in the PEG + Asc group. © 2016 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

2013-01-01

AIM: To compare between 2 and 4 d colon cleansing protocols. METHODS: Children who were scheduled for colonoscopy procedure (2010-2012) for various medical reasons, were recruited from the pediatric gastroenterology clinic at Marshall University School of Medicine, Huntington, WV. Exclusion criteria were patients who were allergic to the medication used in the protocols [polyethylene glycol (PEG) 3350, Bisacodyl], or children with metabolic or renal diseases. Two PEG 3350 protocols for 4 d (A) and 2 d (B) were prescribed as previously described. A questionnaire describing the volume of PEG consumed, clinical data, and side effects were recorded. Colon preparation was graded by two observers according to previously described method. Main outcome measurements: Rate of adequate colon preparation. RESULTS: A total of 78 patients were considered for final calculation (group A: 40, group B: 38). Age and stool consistency at the last day was comparable in both groups, but the number of stools/day was significantly higher in group B (P = 0.001). Adequate colon preparation was reached in 57.5% (A) and 73.6% (B), respectively (P = 0.206). Side effects were minimal and comparable in both groups. There was no difference in children’s age, stool characteristics, or side effects between the children with adequate or inadequate colon preparation. Correlation and agreement between observers was excellent (Pearson correlation = 0.972, kappa = 1.0). CONCLUSION: No difference between protocols was observed, but the 2 d protocol was superior for its shorter time. Direct comparison between different colon cleansing protocols is crucial in order to establish the “gold standard” protocol for children. PMID:23596539

Multiparametric and semiquantitative scoring systems for the evaluation of mouse model histopathology - a systematic review

PubMed Central

2013-01-01

Background Histopathology has initially been and is still used to diagnose infectious, degenerative or neoplastic diseases in humans or animals. In addition to qualitative diagnoses semiquantitative scoring of a lesion`s magnitude on an ordinal scale is a commonly demanded task for histopathologists. Multiparametric, semiquantitative scoring systems for mouse models histopathology are a common approach to handle these questions and to include histopathologic information in biomedical research. Results Inclusion criteria for scoring systems were a first description of a multiparametric, semiquantiative scoring systems which comprehensibly describe an approach to evaluate morphologic lesion. A comprehensive literature search using these criteria identified 153 originally designed semiquantitative scoring systems for the analysis of morphologic changes in mouse models covering almost all organs systems and a wide variety of disease models. Of these, colitis, experimental autoimmune encephalitis, lupus nephritis and collagen induced osteoarthritis colitis were the disease models with the largest number of different scoring systems. Closer analysis of the identified scoring systems revealed a lack of a rationale for the selection of the scoring parameters or a correlation between scoring parameter value and the magnitude of the clinical symptoms in most studies. Conclusion Although a decision for a particular scoring system is clearly dependent on the respective scientific question this review gives an overview on currently available systems and may therefore allow for a better choice for the respective project.

Acute appendicitis is a common but elusive surgical condition and remains a diagnostic dilemma. It has many clinical mimickers and diagnosis is primarily made on clinical grounds, leading to the evolution of clinical scoring systems for pin pointing the right diagnosis. The modified Alvarado and RIPASA scoring systems are two important scoring systems, for diagnosis of acute appendicitis. We prospectively compared the two scoring systems for diagnosing acute appendicitis in 50 patients presenting with right iliac fossa pain. The RIPASA score correctly classified 88 % of patients with histologically confirmed acute appendicitis compared with 48.0 % with modified Alvarado score, indicating that RIPASA score is more superior to Modified Alvarado score in our clinical settings.

To identify websites providing information about early pregnancy loss and compare this information with published guidelines from the Royal College of Obstetricians and Gynaecologists (RCOG). The value of 'Silberg' and 'Health on the net (HON)' website scoring systems in predicting the information provided via websites identified was assessed. A cross-sectional survey. Nineteen websites identified via two search engines (http://www.lycos.co.uk and http://www.msn.co.uk). Websites were searched for specific information in a structured manner and then scored by two independent observers against the website scoring systems and against a scoring system derived from guidelines published by the RCOG. Website scores against the scoring systems and against RCOG guidelines. Information concerning miscarriage contained within these websites was poor and scored accordingly against the RCOG guidelines (median score, 4.5/8). The website scoring systems did not predict the RCOG scores for a website (HON score R(S)=0.193 (95% confidence interval from -0.286 to 0.595), Silberg score, R(S)=0.035 (95% confidence interval from -0.426 to 0.482)). Few relevant websites were identified despite searching a large number via two search engines. The websites found did not answer our specific questions and consequently scored poorly against the RCOG guidelines. RCOG scores did not correlate with either scoring system. Web-based information for women attending with early pregnancy complications needs to be easily accessed and comprehensive. Written information given to women when seen with early pregnancy complications should include details of available comprehensive websites. Professional organisations, colleges or Government agencies should provide this type of information.

Scoring systems for outcome prediction in patients with perforated peptic ulcer

PubMed Central

2013-01-01

Background Patients with perforated peptic ulcer (PPU) often present with acute, severe illness that carries a high risk for morbidity and mortality. Mortality ranges from 3-40% and several prognostic scoring systems have been suggested. The aim of this study was to review the available scoring systems for PPU patients, and to assert if there is evidence to prefer one to the other. Material and methods We searched PubMed for the mesh terms “perforated peptic ulcer”, “scoring systems”, “risk factors”, ”outcome prediction”, “mortality”, ”morbidity” and the combinations of these terms. In addition to relevant scores introduced in the past (e.g. Boey score), we included recent studies published between January 2000 and December 2012) that reported on scoring systems for prediction of morbidity and mortality in PPU patients. Results A total of ten different scoring systems used to predict outcome in PPU patients were identified; the Boey score, the Hacettepe score, the Jabalpur score the peptic ulcer perforation (PULP) score, the ASA score, the Charlson comorbidity index, the sepsis score, the Mannheim Peritonitis Index (MPI), the Acute physiology and chronic health evaluation II (APACHE II), the simplified acute physiology score II (SAPS II), the Mortality probability models II (MPM II), the Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity physical sub-score (POSSUM-phys score). Only four of the scores were specifically constructed for PPU patients. In five studies the accuracy of outcome prediction of different scoring systems was evaluated by receiver operating characteristics curve (ROC) analysis, and the corresponding area under the curve (AUC) among studies compared. Considerable variation in performance both between different scores and between different studies was found, with the lowest and highest AUC reported between 0.63 and 0.98, respectively. Conclusion While the Boey score and the ASA score are most commonly used to predict outcome for PPU patients, considerable variations in accuracy for outcome prediction were shown. Other scoring systems are hampered by a lack of validation or by their complexity that precludes routine clinical use. While the PULP score seems promising it needs external validation before widespread use. PMID:23574922

Introduction: We evaluate the efficacy of the Peristeen (Coloplast A/S, Kokkedal, Denmark) transanal irrigation (TAI) system, as a stool cleansing mechanism, to gain stool continence in children who need reconstructive bladder surgery and have fecal incontinence. Methods: We prospectively evaluated children with neuropathic bladder and bowel dysfunction who were intended for reconstructive bladder surgery and the Malone antegrade continence enema (MACE) procedure. All patients were started on the Peristeen TAI system at least 3 months before surgery to assess their response. Each patient’s bowel function, frequency of using the system, satisfaction (and that of their parents) and diaper independency were evaluated before and after reconstructive surgery. Results: We included 18 patients (11 female, 7 male) who were evaluated from April 2006 to the present. The mean age of the group was 7.6 years (range: 4–15). Fifteen patients (83.3%) showed complete dryness from stools. Of the 15 patients, 8 (53.3%) were able to be diaper-free, while 6 continued wearing diapers due to fear of soiling and 1 due to urinary incontinence. The patients underwent reconstructive bladder surgery and continued to use the Peristeen TAI system with the same results postoperatively. The main limitation of this study is the small number of patients included, although this is a very specific patient group. Conclusion: Our initial results suggest that the Peristeen TAI system is a successful conservative substitute for the MACE procedure in children who require reconstructive bladder surgery.

This study aims to investigate the feasibility and performance of a two-step scoring system of ultrasound imaging in the diagnosis of prostate cancer. 75 patients with 888 consecutive histopathologically verified lesions were included in this study. Step 1, an initial 5-point scoring system was developed based on conventional transrectal ultrasound (TRUS). Step 2, a final scoring system was evaluated according to contrast-enhanced transrectal ultrasound (CE-TRUS). Each lesion was evaluated using the two-step scoring system (step 1 + step 2) and compared with only using conventional TRUS (step 1). 888 lesions were histologically verified: 315 of them were prostate cancer from 46 patients and 573 were benign prostatic hypertrophy (BPH) from 29 patients. According to the two-step scoring system, 284 lesions were upgraded and 130 lesions were downgraded from step 1 to step 2 (this means using step 2 to assess the results by step 1). However, 96 cases were improperly upgraded after step 2 and 48 malignant lesions were still missed after step 2 as score-1. For the two-step scoring system, the sensitivity, specificity, and accuracy were 84.7%, 83.2%, and 83.7%, respectively, versus 22.8%, 96.6%, and 70.4%, respectively, for conventional TRUS. The area under the ROC curve (AUC) for lesion diagnosis was 0.799-0.952 for the two-step scoring system, versus 0.479-0.712 for conventional TRUS. The difference in the diagnostic accuracy of the two-step scoring system and conventional TRUS was statistically significant (P<0.0001). The two-step scoring system was straightforward to use and achieved a considerably accurate diagnostic performance for prostate cancer. The application of the two-step scoring system for prostate cancer is promising.

Degeneration of intervertebral discs and facet joints is one of the most frequently encountered spinal disorders. In order to describe and quantify degeneration and evaluate a possible relationship between degeneration and biomechanical parameters, e.g., the intervertebral range of motion and intradiscal pressure, a scoring system for degeneration is mandatory. However, few scoring systems for the assessment of degeneration of the cervical spine exist. Therefore, two separate objective scoring systems to qualitatively and quantitatively assess the degree of cervical intervertebral disc and facet joint degeneration were developed and validated. The scoring system for cervical disc degeneration consists of three variables which are individually scored on neutral lateral radiographs: "height loss" (0-4 points), "anterior osteophytes" (0-3 points) and "endplate sclerosis" (0-2 points). The scoring system for facet joint degeneration consists of four variables which are individually scored on neutral computed tomography scans: "hypertrophy" (0-2 points), "osteophytes" (0-1 point), "irregularity" on the articular surface (0-1 point) and "joint space narrowing" (0-1 point). Each variable contributes with varying importance to the overall degeneration score (max 9 points for the scoring system of cervical disc degeneration and max 5 points for facet joint degeneration). Degeneration of 20 discs and facet joints of 20 patients was blindly assessed by four raters: two neurosurgeons (one senior and one junior) and two radiologists (one senior and one junior), firstly based on first subjective impression and secondly using the scoring systems. Measurement errors and inter- and intra-rater agreement were determined. The measurement error of the scoring system for cervical disc degeneration was 11.1 versus 17.9% of the subjective impression results. This scoring system showed excellent intra-rater agreement (ICC = 0.86, 0.75-0.93) and excellent inter-rater agreement (ICC = 0.78, 0.64-0.88). Surgeons as well as radiologists and seniors as well as juniors obtained excellent inter- and intra-rater agreement. The measurement error of the scoring system for cervical facet joint degeneration was 20.1 versus 24.2% of the subjective impression results. This scoring system showed good intra-rater agreement (ICC = 0.71, 0.42-0.89) and fair inter-rater agreement (ICC = 0.49, 0.26-0.74). Both scoring systems fulfilled the criteria for recommendation proposed by Kettler and Wilke. Our scoring systems can be reliable and objective tools for assessing cervical disc and facet joint degeneration. Moreover, the scoring system of cervical disc degeneration was shown to be experience- and discipline-independent.

Currently there is a situation that makes it difficult to provide the population with quality drinking water for the sanitary-hygienic requirements. One of the urgent problems is the need for water disinfection. Since the emergence of microorganisms that are pathogens transmitted through water such as typhoid, cholera, etc. requires constant cleansing of waters against pathogenic bacteria. In the water treatment process is destroyed up to 98% of germs, but among the remaining can be pathogenic viruses, the destruction of which requires special handling. As a result, the conducted research the following methods have been proposed for combating harmful microorganisms: sterilization of water by laser radiation and using a UV lamp.

Four candidate cleansing agents evaluated in terms of potential hazards to crew members included two soaps (Neutrogena bar soap and Olive Leaf Liquid), one nonfoaming surfactant (Miranol JEM), and one laundry detergent (sodium dodecylbenzene sulfonate). None of the four exhibited adverse dermatological effects from skin patch tests or supported growth of potentially pathogenic microorganisms. Aqueous solutions of Neutrogena did support a mold species. Neutrogena and Miranol JEM were used in a simulated Skylab personal hygiene regimen with no adverse effects on skin or skin microflora. Based on our results, each of these agents appear to be a promising candidate material for the use intended.

Lipopeptides are biosurfactants extensively used in cosmetics. The consumption of cosmetics containing lipopeptides is increasing as a result of the exceptional surface properties and diverse biological activities of lipopeptides which facilitate a vast number of applications not only in the pharmaceutics industry which includes cosmetics but also in the food industry. Cosmetics containing lipopeptides are available in various dosage forms according to their beneficial surface properties, which include anti-wrinkle and moisturizing activities and cleansing cosmetics. The microbial production of lipopeptides particularly those with biological and surface activities applicable to cosmetics are summarized based on appropriate studies and patents up to the year 2008 to manage the information and sufficiently review the data.

This is a case study of a family that survived genocide and a discussion of families and massive psychic trauma. This family, like many others from Bosnia-Herzegovina, was driven from their home by Serb forces-"ethnically cleansed"-then eventually escaped to Croatia, and was later resettled in the United States. They were referred to us, a group of mental health professionals who established the Bosnian Refugee Trauma Program at the Yale Psychiatric Institute (YPI). We have done clinical, testimony, and research work with the refugee families from Bosnia who resettled in our region, described in part in prior reports (Weine, Becker et al. 1995a, 1995b; Weine and Laub 1995).

The Clock Drawing Test is a frequently used cognitive screening test with several scoring systems in elderly populations. We compare simple and complex scoring systems and evaluate the usefulness of the combination of the Clock Drawing Test with the Mini-Mental State Examination to detect patients with mild cognitive impairment. Patients with amnestic mild cognitive impairment (n = 48) and age- and education-matched controls (n = 48) underwent neuropsychological examinations, including the Clock Drawing Test and the Mini-Mental State Examination. Clock drawings were scored by three blinded raters using one simple (6-point scale) and two complex (17- and 18-point scales) systems. The sensitivity and specificity of these scoring systems used alone and in combination with the Mini-Mental State Examination were determined. Complex scoring systems, but not the simple scoring system, were significant predictors of the amnestic mild cognitive impairment diagnosis in logistic regression analysis. At equal levels of sensitivity (87.5%), the Mini-Mental State Examination showed higher specificity (31.3%, compared with 12.5% for the 17-point Clock Drawing Test scoring scale). The combination of Clock Drawing Test and Mini-Mental State Examination scores increased the area under the curve (0.72; p < .001) and increased specificity (43.8%), but did not increase sensitivity, which remained high (85.4%). A simple 6-point scoring system for the Clock Drawing Test did not differentiate between healthy elderly and patients with amnestic mild cognitive impairment in our sample. Complex scoring systems were slightly more efficient, yet still were characterized by high rates of false-positive results. We found psychometric improvement using combined scores from the Mini-Mental State Examination and the Clock Drawing Test when complex scoring systems were used. The results of this study support the benefit of using combined scores from simple methods.

We evaluated the performance of seven existing risk scoring systems in predicting advanced colorectal neoplasia in an asymptomatic Chinese cohort. We prospectively recruited 5,899 Chinese subjects aged 50-70 years in a colonoscopy screening programme(2008-2014). Scoring systems under evaluation included two scoring tools from the US; one each from Spain, Germany, and Poland; the Korean Colorectal Screening(KCS) scores; and the modified Asia Pacific Colorectal Screening(APCS) scores. The c-statistics, sensitivity, specificity, positive predictive values(PPVs), and negative predictive values(NPVs) of these systems were evaluated. The resources required were estimated based on the Number Needed to Screen(NNS) and the Number Needed to Refer for colonoscopy(NNR). Advanced neoplasia was detected in 364 (6.2%) subjects. The German system referred the least proportion of subjects (11.2%) for colonoscopy, whilst the KCS scoring system referred the highest (27.4%). The c-statistics of all systems ranged from 0.56-0.65, with sensitivities ranging from 0.04-0.44 and specificities from 0.74-0.99. The modified APCS scoring system had the highest c-statistics (0.65, 95% C.I. 0.58-0.72). The NNS (12-19) and NNR (5-10) were similar among the scoring systems. The existing scoring systems have variable capability to predict advanced neoplasia among asymptomatic Chinese subjects, and further external validation should be performed.

To assess and compare the predictive ability of three risk evaluation systems (SinoSCORE, EuroSCORE II and the STS risk evaluation system) in patients aged ≥70, and who underwent coronary artery bypass grafting (CABG) in East China. Three risk evaluation systems were applied to 1,946 consecutive patients who underwent isolated CABG from January 2004 to September 2016 in two hospitals. Patients were divided into two subsets according to their age: elderly group (age ≥70) with a younger group (age <70) used for comparison. The outcome of interest in this study was in-hospital mortality. The entire cohort and subsets of patients were analyzed. The calibration and discrimination in total and in subsets were assessed by the Hosmer-Lemeshow and the C statistics respectively. Institutional overall mortality was 2.52%. The expected mortality rates of SinoSCORE, EuroSCORE II and the STS risk evaluation system were 0.78(0.64)%, 1.43(1.14)% and 0.78(0.77)%, respectively. SinoSCORE achieved the best discrimination (the area under the receiver operating characteristic curve (AUC) = 0.829), followed by the STS risk evaluation system (AUC = 0.790) and EuroSCORE II (AUC = 0.769) in the entire cohort. In the elderly group, the observed mortality rate was 4.82% while it was 1.38% in the younger group. SinoSCORE (AUC = .829) also achieved the best discrimination in the elderly group, followed by the STS risk evaluation system (AUC = .730) and EuroSCORE II (AUC = 0.640) while all three risk evaluation systems all had good performances in the younger group. SinoSCORE, EuroSCORE II and the STS risk evaluation system all achieved positive calibrations in the entire cohort and subsets. The performance of the three risk evaluation systems was not ideal in the entire cohort. In the elderly group, SinoSCORE appeared to achieve better predictive efficiency than EuroSCORE II and the STS risk evaluation system.
