Background: Painful bladder syndrome/interstitial cystitis (PBS/IC) is defined as a syndrome of urgency, frequency, and suprapubic pain in the absence of positive urine culture or obvious bladder pathology. As no specific etiology has been identified yet, no specific methodology exists for diagnosis of this condition. One potential etiology of PBS/IC is inflammation of the bladder mucosa associated with abnormal angiogenesis and ulcerative lesions. The purpose of this study was to examine the feasibility of using transcutaneous near infrared spectroscopy (NIRS) of the bladder to monitor tissue oxygenation and hemodynamics as a means of differentiating subjects diagnosed with PBS/IC from those with other bladder conditions. Methods: Twenty-four adult patients with lower urinary tract dysfunction were divided into 2 groups, PBS/IC and non-PBS/IC after standard diagnostic investigations. Detrusor oxygen saturation percentage (TSI%) was measured in all subjects while they were at rest in a supine position, using a spatially resolved (SR) NIRS instrument. Mean values of detrusor TSI% were significantly different between the two groups (74.2%+/-4.9 in PBS/IC vs. 63.6%+/-5.5 in non-PBS/IC, P<0.0005). Results: Noninvasive NIRS interrogation of the bladder demonstrated that patients diagnosed as having PBS/IC had significantly higher detrusor oxygen saturation at rest. Conclusions: SR-NIRS as a feasible non-noninvasive entity for use in the evaluation of patients for the presence or absence of physiologic changes associated with PBS/IC.

Interstitial cystitis/painful bladder syndrome (IC/PBS) at present is a symptom-based diagnosis. The Interstitial Cystitis Symptom Index (ICSI), also known as the O'Leary-Sant Symptom Index, is a widely used scale that assesses the four cardinal symptoms of IC/PBS (ie, bladder pain, urgency, frequency, and nocturia), by asking how often each is experienced. In an ongoing case-control study of recent-onset IC/PBS, we compared the ICSI with a series of questions that addressed the severity of these symptoms. Recruiting nationally, we enrolled women with IC/PBS symptoms of 12 months' duration or less. We assessed the severity of pain, frequency, and urgency using Likert and categorical scales, and how often these symptoms were experienced using the ICSI. We compared these scales by frequency distributions and interscale correlations. In 138 women with recent-onset IC/PBS, the scores for frequency were correlated and, for pain, appeared to be complementary. However, for urgency, the ICSI question of "the strong need to urinate with little or no warning" consistently yielded lower scores than the severity question of "the compelling urge to urinate that is difficult to postpone." Some patients denied urgency to the ICSI question yet reported intense urgency to the severity question. Compared with the severity question, the ICSI underestimated the prevalence and degree of urgency. This observation is consistent with the views of others that sudden urgency does not define the sensation experienced by many patients with IC/PBS. Clarifying this symptom description may assist in developing a usable case definition for IC/PBS.

We evaluate the efficacy of hyaluronate acid instillation for treatment of interstitial cystitis (IC). From March 2008 to May 2009, a prospective study included 31 patients. We used the new definition of IC established by the ICS in 2002. Patients have a urinalysis, a cystoscopy, a hydrodistension test and bladder biopsies. The urodynamic evaluation was not systematic. Patients received weekly six instillations of 40mg (50ml) intravesical hyaluronate acid. We evaluated the efficacy and safety of treatment with two specific questionnaires of interstitial cystitis filled before and after 6 weeks of treatment: the O'Leary-Sant and Pelvic pain and Urgency/Frequency (PUF). Four groups were defined: good response, partial response, poor response and no response. They were composed by 14 patients (45%), two (7%), seven (22%) and eight patients (26%). We obtained 52% positive response (good response and partial response) after 6 weeks of treatment. Patients with cystoscopy and histology abnormal had a response rate of 60%. No serious side effects were observed. Hyaluronate acid has a place in the treatment of interstitial cystitis with an efficiency comparable to other treatments and good tolerance. The response rate to treatment can be improved by better selection of patients, particularly those having a cystoscopy and histology abnormal. Copyright © 2010 Elsevier Masson SAS.

Bladder pain syndrome/interstitial cystitis: a sense of urgency.

Hanno, Philip M; Chapple, Chris R; Cardozo, Linda D

A classic triad of symptoms (bladder pain, urinary frequency, and urgency) has served to define bladder pain syndrome/painful bladder syndrome/interstitial cystitis (BPS/PBS/IC) syndrome. BPS/PBS/IC is a distinct condition and it is likely that the urgency experienced by these patients differs from that experienced by those with overactive bladder syndrome. It is unclear how best to define urgency in the BPS/PBS/IC setting. Differences in the other primary symptoms associated with these conditions probably influence how urgency is perceived. Advances in research into the pathophysiology of urgency and underlying disease processes will help to optimize both the diagnosis and treatment of BPS/PBS/IC.

Bladder pain is a characteristic disorder of interstitial cystitis. Diazepam is well known for its antispasmodic activity in the treatment of muscular hypertonus. The aim of this work was to develop and characterize vaginal pessaries as an intravaginal delivery system of diazepam for the treatment of interstitial cystitis. In particular, the performance of two types of formulations, with and without beta-glucan, was compared. In particular, the preparation of pessaries, according to the modified Pharmacopeia protocol, the setup of the analytical method to determine diazepam, pH evaluation, dissolution profile, and photostability assay were reported. Results showed that the modified protocol permitted obtaining optimal vaginal pessaries, without air bubbles, with good consistency and handling and with good pH profiles. In order to determine the diazepam amount, calibration curves with good correlation coefficients were obtained, by the spectrophotometric method, using placebo pessaries as matrix with the addition of diazepam standard solution. This method was demonstrated sensible and accurate to determine the amount of drug in batches. Dissolution profiles showed a complete diazepam release just after 15 minutes, even if beta-glucan pessaries released drug more gradually. Finally, a possible drug photodegradation after exacerbated UV-visible exposition was evaluated. PMID:26555976

Bladder pain syndrome/interstitial cystitis (BPS/IC) is a disabling chronic condition that affects up to 7% of women in the USA. In men, BPS/IC seems to be less common, but might be underestimated because it can be confused with chronic prostatitis. The aetiology and pathophysiology of BPS/IC are not well understood. Consequently, diagnosis and treatment is challenging and most therapies used to date are off-label. These therapies include bladder instillation with dimethyl sulfoxide (DMSO) and BCG, as well as hyperbaric oxygen therapy. Overall, botulinum neurotoxin A injection, intravesical sodium hyaluronate instillation and DMSO instillation seem to be the best-performing treatments, with response rates of 79%, 76% and 75%, respectively, and can be used effectively as second-line or third-line therapies for BPS/IC. However, additional high-quality randomized controlled trials are necessary to improve the available data.

The present study explores the influence of psychosocial adversities on the etiology and progress of interstitial cystitis (IC). A systematic survey of the childhood risk factors was carried out using a specially developed, structured interview for pain patients (MSBA-Mainzer Strukturierte Biographische Anamnese) and additionally the Brief Symptom Inventory (BSI). Essentially a descriptive evaluation was performed. Thirty IC patients who fulfilled the current diagnostic criteria participated in the study. The investigation showed higher values for relevant childhood adversities in IC patients. A poor emotional relationship with both parents, chronic diseases of the parents, and physical maltreatment were frequently reported. In the cumulative adverse childhood experience score IC patients showed higher levels than published data of healthy control groups. The contemporary social history did not show relevant psychosocial adversities. The quality of life is extremely reduced because of IC symptoms. The BSI showed high levels especially in the dimensions somatization, anxiety, and phobic anxiety. The results of this study argue for a participatory role of psychosomatic factors in the assumed multifactorial etiology of interstitial cystitis.

No clinical characteristic picture and impact of symptoms on quality of life (QOL) of interstitial cystitis (IC) patients in Taiwan had been reported. This paper is intended to provide preliminary descriptive results of IC research in Taiwan. A total of 319 patients, based on National Institute of Arthritis, Diabetes, Digestive and Kidney Diseases (NIDDK) criteria, were enrolled in the study from February 2004 through March 2006. Evaluation data included baseline demographic information, patient and family medical history, dietary effects, pregnancy data, sexual relationships with symptoms, and impact of symptoms on quality of life. The main responsibility of the hospitals discussed was patient care and data collection. Taichung Hospital presents the results. The Interstitial Cystitis Database (ICDB) patients were predominantly female, that is, 86% of the total, with an average enrollment age of 46. The analysis of various symptoms indicates the following distribution: (i) 94% frequency; (ii) 80% pain; (iii) 53% nocturia; (iv) 43% urgency; and (v) 10% associated incontinence. Approximately 83% reported pain over the bladder while in full stage, and 74% reported pain relief after voiding. The predominant characteristic of pain was full sensation (54%) with the predominant position on low abdominal area (52%). Moreover, 80% reported sleeping disturbance due to disease, and 66% reported difficulty in performing daily work. Interstitial cystitis patients in Taiwan have lower economic status but lower impact on QOL than Western patients. However, the sexual-related pain and sleeping disorder were higher than previously thought and deserve our attention. Accordingly, this research provides a foundation for further investigations of baseline associations and longitudinal trends. © 2013 Wiley Publishing Asia Pty Ltd.

Many clinicians have suggested that a history of bladder and bowel dysfunction (BBD) in childhood predisposes to the development of interstitial cystitis/bladder pain syndrome (IC/BPS) or irritable bowel syndrome (IBS) in adulthood. We hypothesized that BBD symptoms in childhood would predict the IBS-associated phenotype in adult IC/BPS patients. Consecutive female patients (n=190) with a diagnosis of IC/BPS were administered a modified form of a clinical BBD questionnaire (BBDQ) to capture childhood BBD-like symptoms, as well as Interstitial Cystitis Symptoms Index (ICSI), Interstitial Cystitis Problem Index (ICPI), Pelvic Pain and Urgency/Frequency (PUF) questionnaires and UPOINT categorization. Patients were stratified to IBS-positive or IBS-negative according to clinical assessment of IBS-like symptoms. The 127 patients (67%) identified with IBS-like symptoms recalled significantly higher BBDQ scores than the 63 patients (33%) who were IBS-negative (2.8 vs. 2.3; p=0.05). The IBS-positive patients also reported a higher number of UPOINT domains than their non-IBS counterparts (3.8 vs. 2.9; p=0.0001), while their PUF total scores were significantly higher (13.6 vs. 12.3; p=0.04). IBS-positive patients more often recalled that in childhood they did not have a daily bowel movement (BM) (p=0.04) and had "to push for a BM" (p=0.009). In childhood, they "urinated only once or twice per day" (p=0.03) and recalled "painful urination" more than those without IBS (p=0.03). There were no significant differences between the groups in answers to the other five questions of the BBDQ. Our symptom recollection survey was able to predict the IBS phenotype of IC/BPS based on a childhood BBDQ. Further prospective studies are needed to further evaluate these novel findings.

Complementary and Alternative Therapies as Treatment Approaches for Interstitial Cystitis

PubMed Central

Whitmore, Kristene E

2002-01-01

The management of interstitial cystitis (IC) is predominantly the reduction of the symptoms of frequency, urgency, and pain. Multimodal treatment approaches for IC are helpful in customizing therapy for individual patients. Complementary and alternative therapies are a quintessential addition to the therapeutic armamentarium and frequently include dietary modification, nutraceuticals, bladder training, neuromodulation, stress reduction, and sex therapy. Dietary modification involves elimination of bladder irritants, fluid regulation, and a bowel regimen. Nutraceuticals studied for the treatment of IC include calcium glycerophosphate, L-arginine, mucopolysaccharides, bioflavinoids, and Chinese herbs. Bladder training is effective after pain reduction. The neuromodulation of high-tone pelvic-floor muscle dysfunction is achieved with physical therapy and acupuncture. Stress reduction and sex therapy are best administered by a qualified stress manager and sex therapist. Multimodal, nonconventional management may add efficacy to the treatment of IC. PMID:16986031

The purpose of this study was to describe the use of complementary and alternative medicine (CAM) therapies among interstitial cystitis (IC) patients, patients' perception of CAM therapies' effectiveness, and the association of time since diagnosis with perceived effectiveness of these therapies. In April 2009, the Interstitial Cystitis Association (ICA) initiated an Internet-based survey on CAM. Respondents indicated whether they received an IC diagnosis and how long ago, whether they tried CAM, and who recommended it. On a 5-point scale, respondents rated 49 therapies. For respondents confirming a diagnosis, we used a chi-square goodness-of-fit test to assess which therapies were rated positively or negatively by a majority of patients who tried them. Using separate one-way analyses of variance, we assessed differences in mean perceived effectiveness among groups based on time since diagnosis and conducted post hoc tests, if necessary. Using chi-square tests, we explored the association of time since diagnosis with the use of CAM and the number of therapies tried. A total of 2,101 subjects responded to the survey; 1,982 confirmed an IC diagnosis. Most (84.2 %) had tried CAM, and 55 % said physicians had recommended CAM. Of those trying CAM, 82.8 % had tried diet or physical therapy and 69.2 % other therapies. Of the therapies, 22 were rated positively and 20 negatively; 7 were inconclusive. Therapies patients perceived to be helpful included dietary management and pain management adjuncts such as physical therapy, heat and cold, meditation and relaxation, acupuncture, stress reduction, exercise, and sleep hygiene. Many therapies worked better for those diagnosed recently than for those diagnosed long before. Randomized, placebo-controlled studies are needed to demonstrate which therapies may indeed control IC symptoms and help send research in new and productive directions.

The aim of our study was to test the effect of a more viscous compound than existent hyaluronic acid formulation in helping to restore a defective glycosaminoglycan layer, and therefore in improving Interstitial Cystitis/Painful Bladder Syndrome (IC/PBS) symptoms when administered intravesically in IC/PBS patients. A total of 23 female patients completed the study. Patients received endovesical administration of hyaluronic acid and chondroitin sulfate in normal saline, 40 ml, weekly for 12 weeks and then bi-weekly for 6 months, if there was initial response. After 12 weeks treatment both Interstitial Cystitis Symptom and Problem Index (ICSI/ICPI), pelvic pain and Urgency/Frequency Symptom Scale (PUF) showed a mean significant improvement, which was maintained thereafter. The average number of voidings and mean voiding volumes revealed significant improvement after the 12 weeks' treatment period, with a significant reduction and increase, respectively. Mean voiding volume increased from 143 ml to 191, which apparently was not reflected in a corresponding reduction of number of daily voids (from 15,5 to 14). VAS values decreased from 5,4 to 3,6 (pain) and from 6,0 to 3,5 (urgency) after the treatment cycle, showing a significant improvement. In our preliminary experience, the administration of intravesical hyaluronic acid plus chondroitine sulphate appears to be a safe and efficacious method of treatment in IC/PBS.

This study aimed to describe the psychological functioning of interstitial cystitis/bladder pain syndrome patients utilizing MMPI-2-RF scoring. The MMPI-2 was administered to 60 individuals who reported a diagnosis of IC. Responses were scored in the MMPI-2-RF format. Fifty-one protocols were deemed valid. Elevations were discovered on scales FBS-r (symptom validity), RC1 (somatic complaints), and MLS (malaise). Participants were split into two groups based on extreme elevations on RC1; the high RC1 group produced higher scores on 39 scales including clinically significant elevations on 17 scales. Over 25% of this sample had an emotional component to their physical concerns. This knowledge about the psychological characteristics of IC patients may have clinical utility for physicians and other treatment providers. The results argue strongly for psychological evaluation as a component of IC diagnosis and treatment. Those with significant emotional overlay to their somatic complaints may be best managed through psychological interventions and minimally invasive treatments. Copyright © 2014 Elsevier Inc.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a debilitating chronic disease of unknown etiology. A naturally occurring disease termed feline interstitial cystitis (FIC) reproduces many features of IC/BPS patients. To gain insights into mechanisms underlying IC/BPS, we investigated pathological changes in the lamina propria (LP) of the bladder and proximal urethra in cats with FIC, using histological and molecular methods. Compared to control cat tissue, we found an increased number of de-granulated mast cells, accumulation of leukocytes, increased cyclooxygenase (COX)-1 expression in the bladder LP, and increased COX-2 expression in the urethra LP from cats with FIC. We also found increased suburothelial proliferation, evidenced by mucosal von Brunn’s nests, neovascularization and alterations in elastin content. Scanning electron microscopy revealed normal appearance of the superficial urethral epithelium, including the neuroendocrine cells (termed paraneurons), in FIC urethrae. Together, these histological findings suggest the presence of chronic inflammation of unknown origin leading to tissue remodeling. Since the mucosa functions as part of a “sensory network” and urothelial cells, nerves and other cells in the LP are influenced by the composition of the underlying tissues including the vasculature, the changes observed in the present study may alter the communication of sensory information between different cellular components. This type of mucosal signaling can also extend to the urethra, where recent evidence has revealed that the urethral epithelium is likely to be part of a signaling system involving paraneurons and sensory nerves. Taken together, our data suggest a more prominent role for chronic inflammation and tissue remodeling than previously thought, which may result in alterations in mucosal signaling within the urinary bladder and proximal urethra that may contribute to altered sensations and pain in cats and humans with this

We utilized physician-coded diagnoses and chart reviews to estimate the incidence of interstitial cystitis (IC) in women. A computer search of the Kaiser Permanente database was performed to identify newly coded diagnoses of IC (ICD-9 code 595.1) between May 2002 and May 2005. Chart reviews were performed and patient demographics, diagnosing physicians, and symptom characteristics were recorded. The IC incidence rate was 15 per 100,000 women per year. The mean age of the patients was 51 years (range 31-81 years). The most common presenting symptoms were frequency (70%), dysuria (52%), urgency (50%), suprapubic pain (50%), nocturia (35%), and dyspareunia (13%). Cases diagnosed by primary care physicians had a shorter median symptom duration (9 months) compared with those diagnosed by urologists (1 year) and gynecologists (3 years). IC is an uncommon diagnosis in the community setting, with an incidence rate of 15 per 100,000 women per year.

The diagnosis and treatment of interstitial cystitis/bladder pain syndrome (IC/BPS) has shifted from organ-specific to a multifactorial, multidisciplinary and individualized approach. Patients with refractory and debilitating symptoms may respond to complementary and alternative medical treatments (CAM). Through CAM therapies, practitioners assist the patient to be at the center of their care, empowering them to be emotionally and physically involved. Multi-disciplinary care, including urology, gynecology, gastroenterology, neurology, psychology, physiotherapy and pain medicine, is also identified to be the crux of adequate management of patients with chronic pelvic pain because of its variable etiology. The purpose of this review is to emphasize these changes and discuss management strategies.

Bladder wall nitric oxide production in patients with bladder pain syndrome type 3C is increased compared to undetectable nitric oxide in patients with nonHunner bladder pain syndrome and healthy controls. However, the underlying mechanism/s of the increased nitric oxide production is largely unknown. We compared mRNA expression of a select group of cytokines in patients with bladder pain syndrome/interstitial cystitis type 3C and in pain-free controls. Cold cup biopsies from 7 patients with bladder pain syndrome type 3C and 6 healthy subjects were analyzed. mRNA expression of IL-4, 6, 10 and 17A, iNOS, TNF-α, TGF-β and IFN-γ was estimated by real-time polymerase chain reaction. IL-17 protein expression was determined by immunohistochemistry. Mast cells were labeled with tryptase to evaluate cell appearance and count. IL-6, 10 and 17A, and iNOS mRNA levels as well as the number of mast cells infiltrating the bladder mucosa were significantly increased in patients with bladder pain syndrome type 3C compared to healthy controls. TNF-α, TGF-β and IFN-γ mRNA levels were similar in patients and controls. IL-17A expression at the protein level was up-regulated and localized to inflammatory cells and urothelium in patients with bladder pain syndrome type 3C. Patients with bladder pain syndrome/interstitial cystitis had increased mRNA levels of IL-17A, 10 and 6, and iNOS. IL-17A might be important in the inflammatory process. To our knowledge the increase in IL-17A is a novel finding that may have new treatment implications. Copyright © 2014 American Urological Association Education and Research, Inc.

We compared the rate of mental health disorders in male and female patients with pelvic pain and control subjects. Male patients with chronic prostatitis/chronic pelvic pain syndrome (174) and female patients with interstitial cystitis/painful bladder syndrome (111) were identified from a urology tertiary care clinic population. A control group consisting of 72 men and 175 women was also recruited. Subjects completed self-administered questionnaires that included items about demographics, medical history, medication use and urological symptoms. The Patient Health Questionnaire was used to identify depression and panic disorder. Multiple logistic regression was used to determine odds ratios for the presence of a mental health diagnosis. Mental health disorders were identified in 13% of the chronic prostatitis/chronic pelvic pain syndrome cases and 4% of male controls (OR 2.0, p = 0.04), as well as in 23% of interstitial cystitis/painful bladder syndrome cases and 3% of female controls (OR 8.2, p <0.0001). Disease status (case vs control) (OR 10.4, p = 0.001) and income greater than $50,000 (OR 0.34, p = 0.008) were the only 2 variables independently predictive of the presence of a mental health diagnosis. Age, gender, race/ethnicity and education were not predictive. Medications for anxiety, depression or stress were being taken by 18% of patients with chronic prostatitis/chronic pelvic pain syndrome, 37% of those with interstitial cystitis/painful bladder syndrome, 7% of male controls and 13% of female controls. Depression and panic disorder are significantly more common in men and women with pelvic pain conditions than in controls. Medication use data suggest that anxiety and depression may be more difficult to treat in patients with urological pain syndromes than in controls.

Bladder pain syndrome/interstitial cystitis (BPS/IC) is a common debilitating disease and there has not been consistently effective treatment. We aimed to evaluate all available literature regarding the efficacy and safety of sacral neuromodulation (SNM) for refractory BPS/IC. A comprehensive search of Pubmed, Web of Science and Cochrane Library through May 2016 was conducted. A total of 17 studies enrolling 583 patients were identified. Pooled analyses demonstrated that SNM was associated with great reduction in pelvic pain (weighted mean difference [WMD] -3.99; 95% confidence interval [CI] -5.22 to -2.76; p < 0.00001), Interstitial Cystitis Problem and Symptom Index scores (WMD -6.34; 95% CI -9.57 to -3.10; p = 0.0001; and WMD -7.17; 95% CI -9.90 to -4.45; p < 0.00001, respectively), daytime frequency (WMD -7.45; 95% CI -9.68 to -5.22; p < 0.00001), nocturia (WMD -3.01; 95% CI -3.56 to -2.45; p < 0.00001), voids per 24 hours (WMD -9.32; 95% CI -10.90 to -7.74; p < 0.00001) and urgency (WMD -1.08; 95% CI -1.79 to -0.37; p = 0.003) as well as significant improvement in average voided volume (WMD 95.16 ml; 95% CI 63.64 to 126.69; p < 0.0001). The pooled treatment success rate was 84% (95% CI 76% to 91%). SNM-related adverse events were minimal. Current evidence indicates that SNM might be effective and safe for treating refractory BPS/IC.

In contrast to the inconsistent results of organic causes, it has been found that psychological risk factors are reliably related to functional somatic syndromes (FSSs), including interstitial cystitis/bladder pain syndrome (IC/BPS). Compared to patients with acute cystitis, a subgroup of IC/BPS patients with a history of childhood relational trauma reported intensified unregulated affective states (i.e., anxiety and depression) and trauma-related psychopathology (i.e., dissociation). Nevertheless, it remains unknown whether psychosocial risk factors can be separated from bladder-centric factors. This study aimed to verify whether psychosocial factors such as alexithymia, which is a key psychological factor of FSSs, are less likely to be linked to a low bladder capacity in patients with IC/BPS. Ninety-four female IC/BPS patients were recruited from the outpatient departments of urology, obstetrics, and gynecology. Anxiety, depression, dissociation, childhood relational trauma, and alexithymia were assessed using standardized scales, and anesthetic bladder capacity was examined by cystoscopic hydrodistention. Positive correlations were found between anesthetic bladder capacity and the psychosocial variables, including alexithymia. An increased bladder capacity was associated with anxiety, dissociation, and childhood relational trauma, and a combination of high cognitive and low affective alexithymia mediated the correlations between bladder capacity and the psychosocial variables. Psychosocial variables that are associated with an aversive childhood relational environment and affect dysregulation may constitute a pathogenic trajectory that differs from bladder-centric defects such as a lower bladder capacity. The findings of this study support the notion that IC/BPS in some patients may be due to an FSS. Copyright © 2017 Elsevier Inc. All rights reserved.

Interstitial cystitis/bladder pain syndrome (IC) is associated with significant morbidity, yet underlying mechanisms and diagnostic biomarkers remain unknown. Pelvic organs exhibit neural crosstalk by convergence of visceral sensory pathways, and rodent studies demonstrate distinct bacterial pain phenotypes, suggesting that the microbiome modulates pelvic pain in IC. Stool samples were obtained from female IC patients and healthy controls, and symptom severity was determined by questionnaire. Operational taxonomic units (OTUs) were identified by16S rDNA sequence analysis. Machine learning by Extended Random Forest (ERF) identified OTUs associated with symptom scores. Quantitative PCR of stool DNA with species-specific primer pairs demonstrated significantly reduced levels of E. sinensis, C. aerofaciens, F. prausnitzii, O. splanchnicus, and L. longoviformis in microbiota of IC patients. These species, deficient in IC pelvic pain (DIPP), were further evaluated by Receiver-operator characteristic (ROC) analyses, and DIPP species emerged as potential IC biomarkers. Stool metabolomic studies identified glyceraldehyde as significantly elevated in IC. Metabolomic pathway analysis identified lipid pathways, consistent with predicted metagenome functionality. Together, these findings suggest that DIPP species and metabolites may serve as candidates for novel IC biomarkers in stool. Functional changes in the IC microbiome may also serve as therapeutic targets for treating chronic pelvic pain.

The bladder pain syndrome (BPS) is a spectrum of urological symptoms characterised by bladder pain with typical cystoscopic features. Diagnosis and management of this syndrome may be difficult. There is no evidence-based management approach for the diagnosis or treatment of BPS. The objective of this study was to critically review and summarise the evidence relating to the diagnosis and treatment of the bladder pain syndrome. A review of published data on the diagnosis and treatment of the BPS was performed. Our search was limited to English-language articles, on the "diagnosis", and "management" or "treatment" of "interstitial cystitis" and the "bladder pain syndrome" in "humans." Frequency, urgency and pain on bladder filling are the most common symptoms of BPS. All urodynamic volumes are reduced in patients with BPS. Associated conditions include psychological distress, depression, history of sexual assault, irritable bowel syndrome and fibromyalgia. Cystoscopy remains the test for definitive diagnosis, with visualisation of haemorrhage on cystoreduction. A multidisciplinary treatment approach is essential in the management of this condition. Orally administered amitriptyline is an efficacious medical treatment for BPS. Intravesical hyaluronic acid and local anaesthetic, with/without hydrodistension are among new treatment strategies. Sacral or pudendal neuromodulation is effective, minimally invasive and safe. Surgery is reserved for refractory cases. There remains a paucity of evidence for the diagnosis and treatment of BPS. We encountered significant heterogeneity in the assessment of symptoms, duration of treatment and follow up of patients in our literature review.

For decades, intravesical dimethyl sulfoxide (DMSO) cocktail therapy has been used for the treatment of interstitial cystitis/bladder pain syndrome (IC/BPS), but little is known about its long-term efficacy. We aimed to assess the long-term efficacy of intravesical DMSO/heparin/hydrocortisone/bupivacaine therapy in patients with IC/BPS. Patients with IC/BPS from our institutions who underwent this therapy with >2 years follow-up were surveyed with O'Leary-Sant interstitial cystitis symptom and problem index questionnaires before and after therapy. Chart reviews and telephone surveys were then conducted to determine their posttherapy course. Of 68 eligible women, 55 (80.0%) with a median follow-up of 60 months (range 24-142) were surveyed. Their mean age at therapy onset was 44.8 years and their mean body mass index was 26.2 kg/m 2 . There were statistically significant improvements in O'Leary-Sant and pain scores of 23-47% at both 6 weeks and the end of the follow-up period. At the end of the follow-up period, 19 of the 55 women (34.5%) were cured (requiring no further treatment) and 12 (21.8%) were significantly improved (requiring only ongoing oral medication). Univariate and multivariate analyses showed that DMSO treatment failure was more likely in patients with pretreatment day-time urinary frequency more than 15 episodes per day (OR 1.41), nocturia more than two episodes per night (OR 2.47), maximum bladder diary voided volume <200 ml (OR 1.39) and bladder capacity under anaesthesia <500 ml (OR 1.6). At a median follow-up of 60 months, intravesical DMSO cocktail therapy appeared moderately effective for the treatment of IC/BPS. Treatment failure was more frequent in patients with pretreatment symptoms of reduced bladder capacity.

Intravesical instillation with a hyaluronic acid (HA) solution is an effective treatment for interstitial cystitis/bladder pain syndrome (IC/BPS), but its impact on sexual functioning of patients is not known. The aim of this study was to evaluate the changes in sexual function of women with refractory IC/BPS who underwent a second-line intravesical HA therapy. A total of 103 women diagnosed with refractory IC/BPS were enrolled in this prospective, multicenter study. Sexual function was evaluated using the short form of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire (PISQ-9). Bladder-related symptoms and bother were assessed by the Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI), and a pain visual analog scale (VAS), respectively. Data were analyzed with univariate methods or multivariate logistic regression analysis accordingly. Changes in PISQ-9, ICSI, ICPI, and pain VAS scores after treatment were assessed. Mean age and duration of symptoms was 43.6 ± 11.8 and 5.1 ± 5.0 years, respectively. ICSI, ICPI, and pain VAS scores were significantly (P < 0.001) improved after 1 month and 6 months of treatment. Of the 87 (84.5%) sexually active women evaluated, PISQ-9 total scores improved significantly (P < 0.001) from the baseline (mean 18.9 ± 6.4), after 1 month (20.4 ± 5.8), and 6-months (21.5 ± 5.6) of treatment. Significantly improved PISQ-9 items included "dyspareunia" (P < 0.001) and "negative reactions" (P = 0.015) during sexual intercourse, and "intensity" (P < 0.001) of sexual orgasms. After a logistic regression analysis, we found that a baseline PISQ-9 score was negatively correlated with the duration of IC/BPS symptoms (P = 0.022). Meanwhile, the changes in PISQ-9 scores were positively correlated with the reduction in ICSI scores after treatment (P = 0.045). Intravesical HA is an effective treatment for refractory IC/BPS.

This study aims to evaluate the effectiveness of kenalog injection into Hunner's lesions. All patients had cystoscopy and bladder hydrodistention with corticosteroid injection into Hunner's lesions over a 2.5-year period. Data include patient characteristics and pre- and post-operative validated questionnaires. Spearman Correlation and Wilcoxon t -tests were used for analysis. One hundred patients were reviewed retrospectively. There was a 1.1 point decrease in pain at 12 weeks post-operation (p = 0.435). Urinary frequency decreased from a mean of 11.7 to 9.1 daily episodes (p = 0.05), and nocturia from a mean of 3 to 1.6 nightly episodes (p = 0.008). The use of a corticosteroid may be beneficial to symptom control and improvement in the quality of life of interstitial cystitis/painful bladder syndrome patients. Patients had improved frequency and nocturia 12 weeks post injection.

Squamous cell carcinoma (SCC) of the bladder is a relatively uncommon cause of bladder cancer accounting for <5% of bladder tumors in the western countries. SCC has a slight male predominance and tends to occur in the seventh decade of life. The main presenting symptom of SCC is hematuria, and development of this tumor in the western world is associated most closely with chronic indwelling catheters and spinal cord injuries. A 39-year-old Caucasian female presented with bladder and lower abdominal pain, urinary frequency, and nocturia which was originally believed to be interstitial cystitis (IC) but was later diagnosed as SCC of the bladder. Presentation of SCC without hematuria is an uncommon presentation, but the absence of this symptom should not lead a practitioner to exclude the diagnosis of SCC. This case is being reported in an attempt to explain the delay and difficulty of diagnosis. Background on the risk factors for SCC of the bladder and the typical presenting symptoms of bladder SCC and IC are also reviewed.

Feline idiopathic cystitis (FIC) is the only spontaneous animal model for human interstitial cystitis (IC), as both possess a distinctive chronical and relapsing character. Underlying pathomechanisms of both diseases are not clearly established yet. We recently detected increased urine fibronectin levels in FIC cases. The purpose of this study was to gain further insight into the pathogenesis by assessing interacting partners of fibronectin in urine of FIC affected cats. Several candidate proteins were identified via immunoprecipitation and mass spectrometry. Considerable changes in FIC conditions compared to physiological expression of co-purified proteins were detected by Western blot and immunohistochemistry. Compared to controls, complement C4a and thioredoxin were present in higher levels in urine of FIC patients whereas loss of signal intensity was detected in FIC affected tissue. Galectin-7 was exclusively detected in urine of FIC cats, pointing to an important role of this molecule in FIC pathogenesis. Moderate physiological signal intensity of galectin-7 in transitional epithelium shifted to distinct expression in transitional epithelium under pathophysiological conditions. I-FABP expression was reduced in urine and urinary bladder tissue of FIC cats. Additionally, transduction molecules of thioredoxin, NF-κB p65 and p38 MAPK, were examined. In FIC affected tissue, colocalization of thioredoxin and NF-κB p65 could be demonstrated compared to absent coexpression of thioredoxin and p38 MAPK. These considerable changes in expression level and pattern point to an important role for co-purified proteins of fibronectin and thioredoxin-regulated signal transduction pathways in FIC pathogenesis. These results could provide a promising starting point for novel therapeutic approaches in the future. PMID:23236492

To investigate whether urinary levels of macrophage migration inhibitory factor (MIF) are elevated in interstitial cystitis/bladder pain syndrome (IC/BPS) patients with Hunner lesions and also whether urine MIF is elevated in other forms of inflammatory cystitis. Urine samples were assayed for MIF by enzyme-linked immunosorbent assay. Urine samples from 3 female groups were examined: IC/BPS patients without (N = 55) and with Hunner lesions (N = 43), and non-IC/BPS patients (N = 100; control group; no history of IC/BPS; cancer or recent bacterial cystitis). Urine samples from 3 male groups were examined: patients with bacterial cystitis (N = 50), radiation cystitis (N = 18) and noncystitis patients (N = 119; control group; negative for bacterial cystitis). Urine MIF (mean MIF pg/mL ±  standard error of the mean) was increased in female IC/BPS patients with Hunner lesions (2159 ± 435.3) compared with IC/BPS patients without Hunner lesions (460 ± 114.5) or non-IC/BPS patients (414 ± 47.6). Receiver operating curve analyses showed that urine MIF levels discriminated between the 2 IC groups (area under the curve = 72%; confidence interval 61%-82%). Male patients with bacterial and radiation cystitis had elevated urine MIF levels (2839 ± 757.1 and 4404 ± 1548.1, respectively) compared with noncystitis patients (681 ± 75.2). Urine MIF is elevated in IC/BPS patients with Hunner lesions and also in patients with other bladder inflammatory and painful conditions. MIF may also serve as a noninvasive biomarker to select IC/BPS patients more accurately for endoscopic evaluation and possible anti-inflammatory treatment. Copyright © 2018 Elsevier Inc.

Alterations of microbiota in urine from women with interstitial cystitis

PubMed Central

2012-01-01

Background Interstitial Cystitis (IC) is a chronic inflammatory condition of the bladder with unknown etiology. The aim of this study was to characterize the microbial community present in the urine from IC female patients by 454 high throughput sequencing of the 16S variable regions V1V2 and V6. The taxonomical composition, richness and diversity of the IC microbiota were determined and compared to the microbial profile of asymptomatic healthy female (HF) urine. Results The composition and distribution of bacterial sequences differed between the urine microbiota of IC patients and HFs. Reduced sequence richness and diversity were found in IC patient urine, and a significant difference in the community structure of IC urine in relation to HF urine was observed. More than 90% of the IC sequence reads were identified as belonging to the bacterial genus Lactobacillus, a marked increase compared to 60% in HF urine. Conclusion The 16S rDNA sequence data demonstrates a shift in the composition of the bacterial community in IC urine. The reduced microbial diversity and richness is accompanied by a higher abundance of the bacterial genus Lactobacillus, compared to HF urine. This study demonstrates that high throughput sequencing analysis of urine microbiota in IC patients is a powerful tool towards a better understanding of this enigmatic disease. PMID:22974186

New Aspects in the Differential Diagnosis and Therapy of Bladder Pain Syndrome/Interstitial Cystitis

Diagnosis of bladder pain syndrome/interstitial cystitis (BPS/IC) is presently based on mainly clinical symptoms. BPS/IC can be considered as a worst-case scenario of bladder overactivity of unknown origin, including bladder pain. Usually, patients are partially or completely resistant to anticholinergic therapy, and therapeutical options are especially restricted in case of BPS/IC. Therefore, early detection of patients prone to develop BPS/IC symptoms is essential for successful therapy. We propose extended diagnostics including molecular markers. Differential diagnosis should be based on three diagnostical “columns”: (i) clinical diagnostics, (ii) histopathology, and (iii) molecular diagnostics. Analysis of molecular alterations of receptor expression in detrusor smooth muscle cells and urothelial integrity is necessary to develop patient-tailored therapeutical concepts. Although more research is needed to elucidate the pathomechanisms involved, extended BPS/IC diagnostics could already be integrated into routine patient care, allowing evidence-based pharmacotherapy of patients with idiopathic bladder overactivity and BPS/IC.

Although the etiology of bladder pain syndrome/interstitial cystitis (BPS/IC) is still unclear, a common theme with BPS/IC patients is comorbid disorders which are related to the autonomic nervous system that connects the nervous system to end-organs. Nevertheless, no study to date has reported the association between hyperthyroidism and BPS/IC. In this study, we examined the association of IC/BPS with having previously been diagnosed with hyperthyroidism in Taiwan. Data in this study were retrieved from the Longitudinal Health Insurance Database. Our study consisted of 736 female cases with BPS/IC and 2208 randomly selected female controls. We performed a conditional logistic regression to calculate the odds ratio (OR) for having previously been diagnosed with hyperthyroidism between cases and controls. Of the 2944 sampled subjects, there was a significant difference in the prevalence of prior hyperthyroidism between cases and controls (3.3% vs. 1.5%, p<0.001). The conditional logistic regression analysis revealed that compared to controls, the OR for prior hyperthyroidism among cases was 2.16 (95% confidence interval (CI): 1.27∼3.66). Furthermore, the OR for prior hyperthyroidism among cases was 2.01 (95% CI: 1.15∼3.53) compared to controls after adjusting for diabetes, coronary heart disease, obesity, hyperlipidemia, chronic pelvic pain, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, panic disorder, migraines, sicca syndrome, allergies, endometriosis, and asthma. Our study results indicated an association between hyperthyroidism and BPS/IC. We suggest that clinicians treating female subjects with hyperthyroidism be alert to urinary complaints in this population.

The design of an early mobile health application (app) prototype to manage interstitial cystitis/painful bladder syndrome, a chronic condition characterized by recurrent pain/discomfort in the bladder and pelvic floor, is described. The purpose of this app prototype is to help people who have IC/PBS manage and learn what triggers their symptoms. Another aim of this research was to provide an example of how sex and gender could be included into the design of a health information system. Based on a literature search of common symptoms and challenges faced by people living with IC/PBS, the researcher created an app prototype design including many features: resources for relaxation, mental health, intimacy, pregnancy, and daily life; reminders for appointments, and medication; logs for diet, activity, sleep, pain, menstruation; and a link to a public washroom locator. This prototype will later undergo usability and content evaluation.

Management of interstitial cystitis/bladder pain syndrome (IC/BPS) remains a challenge due to poor understanding on its etiology. Complementary and alternative medicine (CAM), as an optional treatment, has been widely used, because no definitive conventional therapy is available. The different domain of CAM provides miscellaneous treatments for IC/BPS, which mainly include dietary modification, nutraceuticals, bladder training, biofeedback, yoga, massage, physical therapy, Qigong, traditional Chinese medicine and acupuncture. Clinical evidence has shown that each therapy can certainly benefit a portion of IC/BPS patients. However, the target patient group of each therapy has not been well studied and randomized, controlled trials are needed to further confirm the efficacy and reliability of CAM on managing IC/BPS. Despite these limitations, CAM therapeutic characteristics including non-invasive and effectiveness for specific patients allow clinicians and patients to realize multimodal and individualized therapy for IC/BPS.

In recent years, there has been an increasing interest in alternative (complementary) treatments of interstitial cystitis/bladder pain syndrome (IC/BPS). This is due both to the high incidence of IC/BPS and to a lack of effectiveness of conventional treatments. One of the directions of alternative therapies is a traditional Chinese medicine using a special diet, various animal and plant-derived medicines, breathing exercises and acupuncture. This review analyzes the accumulated experience in using traditional Chinese medicine in the treatment of patients with IC/BPS. The presented data indicate that these methods appear to be promising, since they are effective in a significant number of patients, lead to an improvement in their quality of life, are non-invasive and well tolerated. However, due to the lack of clinical studies, the efficacy of this treatment modalities needs to be confirmed.

To assess the direct medical costs, medication, and procedure use associated with interstitial cystitis (IC) in women in the Kaiser Permanente Northwest (KPNW) managed care population. The KPNW electronic medical record was used to identify women diagnosed with IC (n = 239). Each of these patients was matched with three controls according to age and duration in the health plan. Health plan cost accounting data were used to determine the inpatient, outpatient, and pharmacy costs for 1998 to 2003. An analysis of the prescription medication use and cystoscopic and urodynamic procedures commonly associated with IC was also performed. To evaluate for co-morbidities, an automated risk-adjustment model linked to 28 chronic medical conditions was applied to the administrative data sets from both groups. The mean duration from the date of IC diagnosis to the end of the study period was 36.6 months (range 1.4 to 60). The mean yearly costs were 2.4-fold greater for the patients than for the controls ($7100 versus $2994), and the median yearly costs were 3.8-fold greater ($5000 versus $1304). These cost differences were predominantly due to outpatient and pharmacy expenses. Medication and procedure use were significantly greater for the patients than for the controls. These findings were consistent across risk-adjustment model categories, which suggest that the observed cost differences are IC specific. The direct per-person costs of IC are high, with average yearly costs approximately $4000 greater than for the age-matched controls. This cost differential is an underestimate, because the costs preceding the diagnosis, the use of alternative therapies, indirect costs, and the costs of those with IC that is not diagnosed were not included.

Keratin expression profiling of transitional epithelium in the painful bladder syndrome/interstitial cystitis.

Painful bladder syndrome/interstitial cystitis (PBS/IC) is a severely debilitating condition. Its cause is poorly understood; therapy is symptomatic and often unsuccessful. To study urothelial involvement, we characterized the keratin phenotype of bladder urothelium in 18 patients with PBS/IC using a panel of 11 keratin antibodies recognizing simple keratins found in columnar epithelia (keratins 7, 8, 18, and 20) and keratins associated with basal cell compartments of squamous epithelia (keratins 5, 13, 14, and 17). We also tested 2 antibodies recognizing more than 1 keratin also directed against basal cell compartments of squamous epithelia (D5/16 B4 and 34betaE12). Bladder urothelium in PBS/IC showed distinct differences in the profiles of keratins 7, 8, 14, 17, 18, and 20 compared with literature reports for normal bladder urothelium. These were characterized by a shift from the normal bladder urothelial keratin phenotype to a more squamous keratin profile, despite the lack of morphologic evidence of squamous epithelial differentiation and a loss of compartmentalization of keratin expression. The severity of these changes varied between biopsy specimens. Whether these changes are primary or secondary to another underlying condition remains to be determined.

Bladder pain syndrome/interstitial cystitis as a functional somatic syndrome.

PubMed

Warren, John W

2014-12-01

To determine whether bladder pain syndrome/interstitial cystitis (BPS/IC) has the characteristics of a functional somatic syndrome (FSS). There is no accepted definition of an FSS. Consequently, this paper reviewed the literature for common FSS characteristics and for reports that BPS/IC has these characteristics. Eleven articles met inclusion and exclusion criteria and yielded 18 FSS characteristics. BPS/IC patients manifest all but two: the exceptions were normal light microscopic anatomy (after hydrodistention under anesthesia, some BPS/IC bladders have Hunner's lesions and most have petechial hemorrhages) and normal laboratory tests (many BPS/IC patients have hematuria). Petechial hemorrhages and hematuria are probably related and may appear during naturally-occurring bladder distention. Without such distention, then, the 90% of BPS/IC patients without a Hunner's lesion have all the characteristics of an FSS. Comparisons in the opposite direction were consistent: several additional features of BPS/IC were found in FSSs. This systematic but untested method is consistent with but does not test the hypothesis that BPS/IC in some patients might best be understood as an FSS. Like most conditions, BPS/IC is probably heterogeneous; hence only a proportion of BPS/IC cases are likely to be manifestations of an FSS. This hypothesis has several implications. Explorations of processes that connect the FSSs might contribute to understanding the pathogenesis of BPS/IC. Patients with FSSs are at risk for BPS/IC and may benefit from future preventive strategies. Therapies that are useful in FSSs also may be useful in some cases of BPS/IC.

2005-11-01

We performed a prospective, open label study to examine the safety and efficacy of the long-term administration of the tricyclic antidepressant amitriptyline in patients with interstitial cystitis (IC). A total of 94 patients were stratified into 2 groups, namely a National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) group of those who fulfilled NIDDK criteria for IC and a nonNIDDK group of those who presented with characteristic IC symptoms but met at least 1 NIDDK exclusion criterion. Amitriptyline was received strictly at bedtime following an established self-titration protocol without a limitation of the maximum daily dose. Patients reporting improvement in a global response assessment questionnaire were considered treatment responders. Further efficacy measures were changes in pain and urgency, functional bladder capacity and frequency. Changes in the O'Leary-Sant IC index and rating of overall satisfaction with the therapeutic outcome were also reported. Mean study followup +/- SD was 19.0 +/- 12.5 months. The response rate was 64% (60 patients). The overall mean dose was 55 mg (range 12.5 to 150). Side effects occurred in 79 patients (84%), including dry mouth in 79% and weight gain in 59%. Patient overall satisfaction with the therapeutic result was excellent or good in 43 (46%). The dropout rate was 31% (29 patients) after a mean treatment period of 6 weeks at a mean dose of 70 mg. Nonresponse to treatment was the primary reason for dropout in all cases, while side effects contributed to dropout in 25 (86%). Improvement in the various IC symptoms was statistically significant compared with baseline. Long-term administration of amitriptyline is a feasible, safe and effective treatment for IC, provided that the drug is used judiciously to minimize adverse effects. The therapeutic response to amitriptyline was uniformly observed in patients fulfilling NIDDK criteria and in those with the pure clinical diagnosis of IC.

Interstitial cells of Cajal (ICC) are key regulatory cells in the gut. In the colon of patients with severe ulcerative colitis (UC), myenteric ICC had myoid ultrastructural features and were in close contact with nerve terminals. In all patients as opposed to controls, some ICC profiles showed degenerative changes, such as lipid droplets and irregular vacuoles. Nerve terminals often appeared swollen and empty. Glial cells, muscle cells, and fibroblast-like cells (FLC) showed no alterations. FLC enclosed macrophages (MLC), which were in close contact with naked axon terminals. The organization and cytological changes may be of pathophysiological significance in patients with UC.

To examine a self-regulation and coping model for interstitial cystitis/bladder pain syndrome (IC/BPS) that may help us understand the pain experience of patients with chronic IC/BPS. The model tested illness perceptions, illness-focused coping, emotional regulation, mental health and disability in a stepwise method using factor analysis and structural equation modelling. Step 1, explored the underlying constructs. Step 2, confirmed the measurement models to determine the structure/composition of the main constructs. Step 3, evaluated the model fit and specified pathways in the proposed IC/BPS self-regulation model. In all, 217 female patients with urologist diagnosed IC/BPS were recruited and diagnosed across tertiary care centres in North America. The data were collected through self-report questionnaires. An IC/BPS self-regulation model was supported. Physical disability was worsened by patient's negative perception of their illness, attempts to cope using illness-focused coping and poorer emotional regulation. Mental health was supported by perceptions that individuals could do something about their illness, using wellness-focused behavioural strategies and adaptive emotion regulation. The results clarify the complex and unique process of self-regulation in women with IC/BPS, implicating cognitive and coping targets, and highlighting emotional regulation. This knowledge should help clinicians understand and manage these patients' distress and disability. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

This study aimed to investigate oxidative stress in etiopathogenesis by analyzing serum total antioxidant capacity (TAC), total oxidant status (TOS), binding capacity of exogenous cobalt to human albumin (IMA), serum advanced oxidation protein products (AOPP), paraoxonase (PON), arylesterase, IgE, and C-reactive protein (CRP) in bladder pain syndrome/interstitial cystitis (BPS/IC). The study included 16 female patients diagnosed with BPS/IC and 25 healthy female subjects forming the control group. A bladder biopsy was performed on all patients in the BPS/IC group by carrying out cystoscopy with hydrodistention under general anesthesia. The results of serum TAC, TOS, IMA, AOPP, PON, arylesterase, IgE, and CRP of the subjects in both groups were compared. The mean age of the 16 female patients in the BPS/IC group was 43.6 ± 14.5 years, and the mean age of the 25 healthy subjects in the control group was 42.0 ± 10.3 years. According to the criteria of International Society for the Study of Interstitial Cystitis (ESSIC), eight patients were classified as Type 2A, three patients as Type 2B, four patients as Type 2C, and one patient as Type 3C. In the BPS/IC group, while TAC was found significantly lower than in the control group, IMA, IgE, and CRP were found significantly higher (P < 0.05). When binary logistic regression analysis was performed, the created model was determined to have 81.3 % sensitivity and 80 % specifity. In the etiology of BPS/IC, mechanism of oxidative damage comes into prominence. In the diagnosis of BPS/IC, IgE, CRP, and TAC are not specific markers when used separately; however, a higher specifity and sensitivity could be reached when used jointly in the suspected patients.

Our goal was to evaluate the pain response in an LL-37 induced murine model for interstitial cystitis/painful bladder syndrome (IC/PBS). In particular, we sought to characterize the dose dependence, time-course, and relationship of LL-37 induced bladder inflammation and pain. The IC/PBS model was induced in C57Bl/6 mice by instilling 50 μL of LL-37, an immunomodulatory human cathelicidin (anti-microbial peptide), in the bladder for 1 hr. Pain responses were measured using von Frey filaments (0.04 gm to 4.0 gm) before and after LL-37 instillation. Inflammation was evaluated using tissue myeloperoxidase (MPO) assay, gross inspection, and microscopic histologic examination. The dose response experiment demonstrated a graded pain response, with higher concentrations of LL-37 challenge yielding higher pain responses across all stimuli tested. Statistical significance was seen when comparing 1.0 gm von Frey filament results at 320 μM (68 ± 8% response) vs. 0 μM (38 ± 6% response). Interestingly, pain responses did not attenuate across time but increased significantly after 5 (p=0.0012) and 7 days (p=0.0096). Comparison with MPO data suggested that pain responses could be independent of inflammation. We demonstrated within our LL-37 induced IC/PBS model pain occurs in a dose-dependent fashion, pain responses persist beyond the initial point of insult, and our dose response and time course experiments demonstrated that pain was independent of inflammation.

Sacral neuromodulation (SNM) may improve interstitial cystitis/painful bladder syndrome (IC/BPS) symptoms of urinary frequency, urgency and perhaps even pain, but objective measures of improvement are lacking. We evaluated the potential for urinary chemokines to serve as measures of treatment response over time to SNM. Women with IC/BPS undergoing SNM consented for this study. Three-day bladder/pain diaries were collected at baseline and validated Interstitial Cystitis Symptom Problem Index (ICSPI) scores and mid-stream urine specimens were collected at baseline and at 24 weeks after successful implant. Collected urine was screened for infection by dipstick and analyzed for chemokines by luminex xMAP analysis. At baseline (n = 16), urine levels of CXCL-1 positively correlated with pain score (r = 0.63, P = 0.009), urgency (r = 0.61, P = 0.01), ICSPI (r = 0.43, P = 0.09) and daily voids (r = 0.44, P = 0.08). ICSPI and pain scores also positively correlated with sIL-1ra (r = 0.50, P = 0.04) and monocyte chemotactic protein-1 (MCP-1) or CCL2 positively correlated with daily voids (r = 0.45, P = 0.07) only. At 24 weeks, the median ICSPI index fell from 28 to 15 (n = 7, P = 0.008). Urine levels of sIL-1ra (633.8 ± 188.2 vs. 149.9 ± 41.62 pg/mL) and MCP-1 (448.3 ± 11.6 vs. 176.9 ± 46.16 pg/mL) and CCL5 (20.78 ± 4.09 vs. 11.21 ± 4.12 pg/mL) were also significantly reduced at the follow-up relative to baseline values (P = 0.04). Multivariable analysis of data revealed that sIL-1ra and MCP-1 together explained the majority of variance in data. Levels of CXCL-1, CXCL-10, interleukin (IL)-8, vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF) were also reduced at 24 weeks, but differences were not significant. Concomitant decrease in urine levels of chemokines especially MCP-1 was associated with treatment response of SNM. These results

Purpose To evaluate changes in urine markers and symptom scores after bladder distention in interstitial cystitis (IC) patients. Materials and Methods Subjects were 33 new patients with no prior IC treatments. Urine specimens were taken before and one month after bladder distention. University of Wisconsin (UW) symptom scores were done the same day as the urine specimen collection. Urine marker levels and symptom scores before and after distention were compared. Changes in markers were tested for associations with changes in symptom scores and other markers. Pre-distention markers and specific pre-distention symptoms were tested for their association with post-distention symptom improvement. Results After distention, the median total UW score decreased significantly (28.5 before, 10 after, p<0.001). Twelve patients (36%) had at least 30% improvement in UW score, and eight patients (24%) had at least 50% improvement. No pre-distention markers or symptoms predicted which patients would have a good response. Two of the urine markers improved significantly after distention: anti-proliferative factor (APF) activity (median −96% before, −17% after, p< 0.001) and heparin binding-epidermal growth factor-like growth factor (HB-EGF) levels (median 0.34 ng/mg creatinine before, 4.1 after, p<0.001). None of the changes in urine markers associated with changes in symptom scores. Conclusions The median symptom score for newly diagnosed IC patients decreased after distention, but only a minority of patients had at least 30% symptom improvement. Bladder distention altered urine APF activity and HB-EGF levels towards normal, but the mechanism of symptom relief after distention is still unknown. PMID:17222633

BKV was first postulated to be a potential pathogen in 1971 when it was isolated in the urine of a renal transplant recipient. The pathology of BKV is generally confined to the urinary tract. In renal transplant recipients, BKV has been associated with hemorrhagic cystitis, urethral stenosis, and interstitial nephritis. Reports of BKV infection in lung transplant recipients are limited to a few case reports in adult patients. A recent report revealed that up to 32% of adult lung transplant recipients may shed BKV in their urine without symptoms or renal dysfunction. To our knowledge, there are no published reports of pediatric lung transplant recipients with BKV-associated hematuria. We hereby report a case of BKV-induced hemorrhagic cystitis in a pediatric lung transplant recipient.

Abstract Pelvic inflammatory disease (PID) has been investigated in Western countries and identified to be associated with chronic pelvic pain and inflammation. Bladder pain syndrome/interstitial cystitis (BPS/IC) is a complex syndrome that is significantly more prevalent in women than in men. Chronic pelvic pain is a main symptom of BPS/IC, and chronic inflammation is a major etiology of BPS/IC. This study aimed to investigate the correlation between BPS/IC and PID using a population-based dataset. We constructed a case–control study from the Taiwan National Health Insurance program. The case cohort comprised 449 patients with BPS/IC, and 1796 randomly selected subjects (about 1:4 matching) were used as controls. A Multivariate logistic regression model was constructed to estimate the association between BPS/IC and PID. Of the 2245 sampled subjects, a significant difference was observed in the prevalence of PID between BPS/IC cases and controls (41.7% vs 15.4%, P < 0.001). Multivariate logistic regression analysis revealed that the odds ratio (OR) for PID among cases was 3.69 (95% confidence interval [CI]: 2.89–4.71). Furthermore, the ORs for PID among BPS/IC cases were 4.52 (95% CI: 2.55–8.01), 4.31 (95% CI: 2.91–6.38), 3.00 (95% CI: 1.82–4.94), and 5.35 (95% CI: 1.88–15.20) in the <35, 35–49, 50–64, and >65 years age groups, respectively, after adjusting for geographic region, irritable bowel syndrome, and hypertension. Joint effect was also noted, specifically when patients had both PID and irritable bowel disease with OR of 10.5 (95% CI: 4.88–22.50). This study demonstrated a correlation between PID and BPS/IC. Clinicians treating women with PID should be alert to BPS/IC-related symptoms in the population. PMID:26579800

To compare urgency symptoms in women with interstitial cystitis/bladder pain syndrome (IC/BPS) and overactive bladder (OAB). Women with diagnoses of IC/BPS (n=194) and OAB (n=85) were recruited from the clinical practices of Urologists (n=8) and Gynecologists (n=16) with recognized expertise in the diagnosis and management of these conditions. Subjects completed a comprehensive telephone survey about their current symptoms. The questionnaire included 11 questions about urinary urgency. Responses were compared between the two groups. Urgency was commonly reported as a symptom by women with both conditions (81% IC/BPS and 91% OAB). Compared with IC/BPS, urgency in OAB more often resulted in leakage, and was perceived to be more of a problem. In IC/BPS, the urgency was primarily reported as due to pain, pressure, or discomfort, while in OAB the urgency was more commonly due to fear of leakage. However, approximately 40% of women with OAB also report urgency due to pain, pressure, or discomfort. Similar proportions of both groups (∼ 60%) indicated that the urgency occurred "suddenly" instead of more gradually over a period of minutes or hours. Urgency symptoms differed in women diagnosed with IC/BPS versus those diagnosed with OAB, but there was significant overlap. This suggests that "urgency" is not a well-defined and commonly understood symptom that can be utilized to clearly discriminate between IC/BPS and OAB. These findings reinforce the clinical observation that it is often challenging to differentiate between these two conditions. Copyright © 2010 Wiley-Liss, Inc.

Psychosocial factors amplify symptoms of Interstitial Cystitis (IC/BPS). While psychosocial self-management is efficacious in other pain conditions, its impact on an IC/BPS population has rarely been studied. The objective of this review is to learn the prevalence and impact of psychosocial factors on IC/BPS, assess baseline psychosocial characteristics, and offer recommendations for assessment and treatment. Following PRISMA guidelines, primary information sources were PubMed including MEDLINE, Embase, CINAHL, and GoogleScholar. Inclusion criteria included: (i) a clearly defined cohort with IC/BPS or with Chronic Pelvic Pain Syndrome provided the IC/BPS cohort was delineated with quantitative results from the main cohort; (ii) all genders and regions; (iii) studies written in English from 1995 to April 14, 2017; (iv) quantitative report of psychosocial factors as outcome measures or at minimum as baseline characteristics. Thirty-four of an initial 642 articles were reviewed. Quantitative analyses demonstrate the magnitude of psychosocial difficulties in IC/BPS, which are worse than average on all measures, and fall into areas of clinical concern for 7 out of 10 measures. Meta-analyses shows mean Mental Component Score of the Short-Form 12 Health Survey (MCS) of 40.80 (SD 6.25, N = 2912), where <36 is consistent with severe psychological impairment. Averaged across studies, the population scored in the range seen in clinical depression (CES-D 19.89, SD 13.12, N = 564) and generalized anxiety disorder (HADS-A 8.15, SD 4.85, N = 465). The psychological impact of IC/BPS is pervasive and severe. Existing evidence of treatment is lacking and suggests self-management intervention may be helpful. © 2017 Wiley Periodicals, Inc.

Chylothorax is a disease in which chyle leaks and accumulates in the thoracic cavity. Interstitial pneumonia and pneumomediastinum are common thoracic manifestations of dermatomyositis, but chylothorax complicated with dermatomyositis is not reported. We report a case of dermatomyositis with interstitial pneumonia complicated by chylothorax. A 77-year-old woman was diagnosed as dermatomyositis with Gottron's papules, skin ulcers, anti-MDA5 antibody and rapid progressive interstitial pneumonia. Treatment with betamethasone, tacrolimus and intravenous high-dose cyclophosphamide was initiated, and her skin symptoms and interstitial pneumonia improved once. However, right-sided chylothorax began to accumulate and gradually increase, and at the same time, her interstitial pneumonia began to exacerbate, and skin ulcers began to reappear on her fingers and auricles. Although her chylothorax improved by fasting and parenteral nutrition, she died due to further exacerbations of dermatomyositis and interstitial pneumonia in spite of steroid pulse therapy, increase in the betamethasone dosage, additional intravenous high-dose cyclophosphamide and plasma pheresis. An autopsy showed no lesions such as malignant tumors in the thoracic cavity. This is the first report of chylothorax complicated by dermatomyositis with interstitial pneumonia.

Although one prior study reported an association between bladder pain syndrome/interstitial cystitis (BPS/IC) and urinary calculi (UC), no population-based study to date has been conducted to explore this relationship. Therefore, using a population-based data set in Taiwan, this study set out to investigate the association between BPS/IC and a prior diagnosis of UC. This study included 9,269 cases who had received their first-time diagnosis of BPS/IC between 2006 and 2007 and 46,345 randomly selected controls. We used conditional logistic regression analysis to compute the odds ratio (OR) and its corresponding 95 % confidence interval (CI) for having been previously diagnosed with UC between cases and controls. There was a significant difference in the prevalence of prior UC between cases and controls (8.1 vs 4.3 %, p < 0.001). Conditional logistic regression analysis revealed that cases were more likely to have been previously diagnosed with UC than controls (OR = 1.70; 95 % CI = 1.56-1.84) after adjusting for chronic pelvic pain, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, panic disorder, migraine, sicca syndrome, allergy, endometriosis, and asthma. BPS/IC was found to be significantly associated with prior UC regardless of stone location; the adjusted ORs of kidney calculus, ureter calculus, bladder calculus, and unspecified calculus when compared to controls were 1.58 (95 % CI = 1.38-1.81), 1.73 (95 % CI = 1.45-2.05), 3.80 (95 % CI = 2.18-6.62), and 1.83 (95 % CI = 1.59-2.11), respectively. This work generates the hypothesis that UC may be associated with BPS/IC.

It has been reported in an open-label study that the combination of alkalinized lidocaine and heparin can immediately relieve the symptoms of urinary urgency, frequency, and pain associated with interstitial cystitis (IC). This combination has also been reported to relieve pain associated with sex in patients with IC. The aim of this study was to corroborate these findings in a multicenter setting. The study design was a multicenter prospective, double-blind, crossover, placebo-controlled trial. Each participant met all of the clinical National Institute of Diabetes and Digestive and Kidney Diseases criteria (excluding cystoscopy) for IC. Each patient received drug and control, in random order, within 48 hours of enrolling in the study. The primary outcome measure was percent change in pain score (11-point analog pain scale) 12 hours after receiving the drug or control. Secondary measures were the global assessment response (GAR) of symptoms and 12-hour average urgency reduction determined from 11-point urgency scales. Eighteen (18) patients completed the trial. The average reduction of pain over 12 hours was 21% for control and 42% for active drug (P = 0.0363). GAR was 13% for control and 50% for drug (P = 0.0137). Average urgency reduction was 13% for control and 35% for drug (P = 0.0328). The combination of alkalinized lidocaine and heparin provides up to 12 hours of relief from urgency and pain associated with IC. This combination provides significant immediate relief of symptoms for patients with IC. © 2011 International Society for Sexual Medicine.

Objective This study assessed the direct medical costs, medication and procedure use associated with interstitial cystitis (IC) in women in the Kaiser Permanente Northwest (KPNW) managed care population. Methods The KPNW electronic medical record was utilized to identify women diagnosed with interstitial cystitis (n=239). Each of these cases was matched with three controls based on age and duration in the health plan. Health plan cost accounting data were used to determine inpatient, outpatient, and pharmacy costs for 1998-2003. An analysis of prescription medication use, cystoscopic and urodynamic procedures commonly associated with IC was also performed. To evaluate for comorbidities, an automated risk-adjustment model (RxRisk) linked to 28 chronic medical conditions was applied to the administrative datasets from both groups. Results The mean duration from the date of IC diagnosis to the end of the study period was 36.6 months (range 1.4-60). Mean yearly costs were 2.4-fold greater in cases than controls ($7100 vs. $2994), and median yearly costs were 3.8-fold greater ($5000 vs. $1304). These cost differences were predominantly due to outpatient and pharmacy expenses. Medication and procedure use were significantly greater in cases than controls. These findings were consistent across RxRisk categories, which suggest that the observed cost differences are IC-specific. Conclusions The direct per-person costs of IC are high, with average yearly costs approximately $4000 greater than age-matched controls. This cost differential is an underestimate, as costs preceding the diagnosis, use of alternative therapies, indirect costs and costs of those with IC that is not diagnosed are not included.

Unique barrier properties of the urothelial surface membrane permit urine storage without contents leak into the bloodstream. Previous reports suggested that the bladder urothelial barrier might be compromised in interstitial cystitis/painful bladder syndrome (IC/PBS). We examined the changes of tight junction proteins (zonula occludens-1 (ZO-1) and occludin) in IC/PBS patients. Bladder samples were derived from of 32 patients with IC/PBS and eight controls. We detected the tight junction proteins of ZO-1 and occludin expression by immunoblotting, immunohistochemical (IHC) staining and double immunofluorescent (IF) staining with confocal microscopy. Data were analyzed using the Mann-Whitney U-test. Expression of ZO-1 and occludin in the IC/PBS group was reduced compared to the control group by immunoblotting and IHC staining. Also, the thinning and denudation of urothelium were demonstrated in the IC/PBS group by histological study. IF staining showed the interruption of bladder urothelium in IC/PBS patients under confocal microscopy. Our data showed that decreased expression of tight junction proteins (ZO-1 and occludin) and interruption of bladder urothelium in IC/PBS patients. Treatment to repair the discontinuous urothelium may be useful to relieve some clinical symptoms of patients with IC/PBS. Copyright © 2012. Published by Elsevier B.V.

To investigate the overall treatment efficacy and safety of botulinum toxin type A (BoNTA) injections compared with placebo in interstitial cystitis/bladder pain syndrome (IC/BPS). We conducted a systematic review and meta-analysis of the published literature in PubMed, Cochrane Library, and EMBASE on BoNTA use in IC/BPS. Outcome measures included changes of OLS, ICSI, ICPI, VAS, frequency, nocturia, FBC, Qmax, and PVR from baseline and also included adverse events. A total of five studies were included, with a total sample size of 252 subjects (133 subjects in the experimental group and 119 subjects in the control group). The duration of follow-up ranged from 8 to 12 weeks. The BoNTA dosage was from 50 to 200 U. The pooled overall SMD in the mean change of VAS for the BoNTA group versus the placebo group was -0.49 (95 % CI -0.74, -0.23). There were also significant improvements in ICPI and frequency. The other outcomes (ICSI, nocturia, Qmax, and FBC) were not statistically different between the two groups. Although BoNTA is not regulatory approved indication, this first evidence-based systematic review and meta-analysis of BoNTA injection for IC/BPS showed significant differences in efficacy of treatment compared with placebo, especially for pain control, and also showed no differences in the rate of procedure-related adverse events.

Intravesical treatment of bladder pain syndrome/interstitial cystitis: from the conventional regimens to the novel botulinum toxin injections.

Dellis, Athanasios; Papatsoris, Athanasios G

Bladder pain syndrome (BPS) includes interstitial cystitis (IC) and is often used as a synonym of it (i.e., BPS/IC). It is associated with lower urinary tract symptoms as well as with negative cognitive, behavioral, sexual and/or emotional consequences. Unfortunately, none of the numerous existing oral and intravesical treatments have been effective for all of the BPS subtypes and therefore relevant research is ongoing. In this review, the authors analyze the existing literature for the intravesical treatment of BPS/IC with focus on the novel administration of botulinum toxin (BTX). Several intravesical drugs have been studied in the past, including lidocaine, heparin, pentosan polysulfate sodium, dimethyl sulfoxide, chondroitin sulfate, hyaluronic acid as well as investigational drugs such as GM-0111. Recently, intravesical submucosal injections of BTX have been studied in patients with BPS/IC. Most of the recent studies use BTX-A with no serious adverse effects and with satisfactory results in patients who do not respond to oral or standard intravesical therapy. Nevertheless, there is no consensus regarding the best dosage scheme of BTX, the injection sites and the treatment intervals. BTX intravesical administration in patients with BPS/IC is a safe and efficient treatment option; yet the level of evidence of the initial studies is not high. There is still the need for large randomized controlled studies so that a consensus can be reached for the ideal BTX dosage, injection sites and intervals between treatments.

We evaluated 5 different rat models using different agents in order to establish a standard animal model for interstitial cystitis (IC) in terms of the functional and pathologic characteristics of the bladder. Five IC models were generated in 8-week-old female Sprague-Dawley rats via transurethral instillation of 0.1M hydrogen chloride (HCl) or 3% acetic acid (AA), intraperitoneal injection of cyclophosphamide (CYP) or lipopolysaccharide (LPS), or subcutaneous injection of uroplakin II (UPK2). After generating the IC models, conscious cystometry was performed on days 3, 7, and 14. All rats were euthanized on day 14 and their bladders were obtained for histological and pro-inflammatory-related gene expression analysis. In the cystometric analysis, all experimental groups showed significantly decreased intercontraction intervals compared with the control group on day 3, but only the LPS and UPK groups maintained significantly shorter intercontraction intervals than the control group on day 14. The histological analysis revealed that areas with severe urothelial erosion (HCl, AA, and UPK) and hyperplasia (CYP and LPS), particularly in the UPK-treated bladders, showed a markedly increased infiltration of toluidine blue-stained mast cells and increased tissue fibrosis. In addition, significantly elevated expression of interleukin-1b, interleukin-6, myeloperoxidase, monocyte chemotactic protein 1, and Toll-like receptors 2 and 4 was observed in the UPK group compared to the other groups. Among the 5 different agents, the injection of UPK generated the most effective IC animal model, showing consequent urothelial barrier loss, inflammatory reaction, tissue fibrosis stimulation, and persistent hyperactive bladder.

To evaluate the clinical efficacy of bladder hydrodistention and intravesical sodium hyaluronate in the treatment of interstitial cystitis (IC). Twenty-one patients with IC received intravesical sodium hyaluronate therapy under nerve block or intravenous anesthesia. Bladders were perfused with 100 cmH2O perfusion pressure and expanded for 10 min and were later injected with 40 mg/50 mL sodium hyaluronate through the catheter. After 1 h, the perfusion fluid was released. Perfusion was applied once per week, 4 to 6 times as a course of treatment. Under anesthesia, the average bladder capacity was 191.62 ± 88.67 mL, and after bladder expansion, the bladder capacity reached 425.33 ± 79.83 mL (P = .000). There were 2 suspected bladder ruptures after bladder expansion at 6.5 min and 7.2 min. After 10 min of bladder expansion, there were 19 cases of significantly gross hematuria. After treatment, the catheters of 17 patients were removed at 24 h; for the 2 cases of hematuria, catheters were removed at 72 h and for the 2 cases of suspected bladder rupture, catheters were removed after 4 days. After catheter removal, the pain threshold significantly decreased, and the maximum urinary output increased slightly. Compared with values before treatment, the day before the second injection of sodium hyaluronate, the frequency of urination decreased significantly (32.8 vs. 18.5 times/24 h), the maximum urinary output increased significantly (86.7 vs. 151.9 mL), the pain decreased significantly (8.7 vs. 3.0), and the O'Leary-Sant IC score and quality of life score were significantly decreased (30.0 vs. 17.0 and 5.9 vs. 2.4, respectively) (P = .000). Bladder hydrodistention under anesthesia for patients with severe intractable IC produces immediate effectiveness; sodium hyaluronic infusion can alleviate frequent urination and pain, and the efficacy was positively correlated with the duration of treatment.

This study tests the hypothesis that combined melatonin and adipose-derived mesenchymal stem cell (ADMSC, 1.2 × 10(6) given intravenously) treatment offer superior protection against cyclophosphamide (CYP 150 mg/kg)-induced acute interstitial cystitis (AIC) in rats. Male adult Sprague-Dawley rats were treated as follows: sham controls, AIC alone, AIC + melatonin, AIC + ADMSC, and AIC + melatonin +ADMSC. When melatonin was used, it was given as follows: 20 mg/kg at 30 min after CYP and 50 mg/kg at 6 and 18 hr after CYP. Twenty-four-hour urine volume, urine albumin level, and severity of hematuria were highest in AIC rats and lowest in the controls; likewise urine volume was higher in AIC + melatonin rats than in AIC + ADMSC and AIC + melatonin + ADMSC treated rats; in all cases, P < 0.001. The numbers of CD14+, CD74+, CD68+, MIP+, Cox-2+, substance P+, cells and protein expression of IL-6, IL-12, RANTES, TNF-α, NF-κB, MMP-9, iNOS (i.e. inflammatory biomarkers), glycosaminoglycan level, expression of oxidized protein, and protein expression of reactive oxygen species (NOX-1, NOX-2, NOX-4) in the bladder tissue exhibited an identical pattern compared with that of hematuria among the five groups (all P < 0.0001). The integrity of epithelial layer and area of collagen deposition displayed an opposite pattern compared to that of hematuria among all groups (P < 0.0001). The cellular expressions of antioxidants (GR, GPx, HO-1, NQO 1) showed a significant progressive increase form controls to AIC + melatonin + ADMSC (all P < 0.0001). Combined regimen of melatonin and ADMSC was superior to either alone in protecting against CYP-induced AIC. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Objective To compare sickness behaviors (SB) in response to unusual external events (UEE) in healthy cats with those of cats with feline interstitial cystitis (FIC). Design Prospective observational study. Animals 12 healthy cats and 20 donated cats with FIC. Procedures Cats were housed in a vivarium. Sickness behaviors referable to the gastrointestinal and urinary tracts, the skin, and behavior problems were recorded by a single observer for 77 weeks. Instances of UEE (eg, changes in caretakers, vivarium routine, and lack of interaction with the investigator) were identified during 11 of the 77 weeks. No instances of UEE were identified during the remaining 66 weeks, which were considered control weeks. Results An increase in age and exposure to UEE, but not disease status, significantly increased total number of SB when results were controlled for other factors. Evaluation of individual SB revealed a protective effect of food intake for healthy males. An increase in age conferred a small increase in relative risk (RR) for upper gastrointestinal tract signs (RR, 1.2) and avoidance behavior (1.7). Exposure to UEE significantly increased the RR for decreases in food intake (RR, 9.3) and for no eliminations in 24 hours (6.4). Exposure to UEE significantly increased the RR for defecation (RR, 9.8) and urination (1.6) outside the litter box. Conclusions and Clinical Relevance SB, including some of the most commonly observed abnormalities in client-owned cats, were observed after exposure to UEE in both groups. Because healthy cats and cats with FIC were comparably affected by UEE, clinicians should consider the possibility of exposure to UEE in cats evaluated for these signs. PMID:21194324

Patients with a history of bladder pain syndrome/interstitial cystitis (BPS/IC) and who responded poorly or unsatisfactorily with previous treatment were compared taking intravesical hyaluronic acid (HA) or hyaluronic acid-chondroitin sulphate (HA-CS). Patients were treated with intravesical instillation with 50 mL sterile sodium hyalurinic acid (Hyacyst, Syner-Med, Surrey, UK) (n = 32) and sodium hyaluronate 1.6% sodium chondroitin sulphate 2% (Ialuril, Aspire Pharma, UK) (n = 33). Intravesical instillations were performed weekly in first month, every 15 days in the second month and monthly in third and fourth months, for a total of 8 doses. Patients were evaluated using a visual analog pain scale (VAS), interstitial cystitis symptom index (ICSI), interstitial cystitis problem index (ICPI), voiding diary for frequency/nocturia, cystometric bladder capacity and voided volume at the beginning and at 6 months. All patients had a potassium sensitivity test (PST) initially. Wilcoxon and Mann-Whitney U tests were used for statistical analysis. In total, 53 patients met the study criteria. There were 30 patients in the HA-CS group (mean age: 48.47) and 23 patients in the HA group (mean age: 49.61) (p > 0.05). The initial PST was positive in 71.7% patients (38/53) overall with no difference between groups (p > 0.05). Responses for VAS, ICCS, ICPS, 24-hour frequency/nocturia statistically improved in both groups at 6 months. There was no significant difference in symptomatic improvement (p > 0.05). Eight patients had mild adverse events. HA and HA/CS instillation can be effective in BPS/IC patients who do not respond to conservative treatment. An important limitation of our study is that the HA dosage of the 2 treatment arms were different. It would be more appropriate with same HA dosage in both groups; however, there was no commercially available glycosaminoglycan (GAG) substance with same HA dosage for single and combination therapy.

To demonstrate the effects of intravesical dexpanthenol use on bladder histology and lipid peroxidation in a chemical cystitis animal model. Thirty-five New Zealand rabbits were divided into 3 groups. Cystitis was conducted with transurethral intravesical hydrochloric acid instillation on the subjects in groups I and II. Then, Group I subjects were transurethrally administered intravesical dexpanthenol therapy twice a week, Group II subjects were given only intravesical isotonic NaCl instillation, and Group III subjects were administered intravesical isotonic NaCl instillation without conducting chemical cystitis to create the same stress. Treatment schemes of all groups were arranged in the same manner. After 6-week therapy, the rabbits were sacrificed and histopathologic investigations were carried out to demonstrate changes in the urinary bladder. Serum and tissue malondialdehyde (MDA) values were examined to investigate the effect of dexpanthenol on lipid peroxidation. We observed that the basal membrane and mucosal integrity were maintained, inflammatory cells were suppressed, and MDA levels decreased in group I, which received dexpanthenol therapy. However, it was also observed that mucosal integrity was spoiled, numerous inflammatory cells were accumulated, and MDA levels were significantly increased in group II, which was administered isotonic NaCl. In light of our findings, intravesical dexpanthenol therapy could be a new therapeutic approach in the treatment of interstitial cystitis because of its low cost and acceptable side effects.

Manikandan, R.; Kumar, Santosh; Dorairajan, Lalgudi N.

2010-01-01

Severe hemorrhagic cystitis often arises from anticancer chemotherapy or radiotherapy for pelvic malignancies. Infectious etiologies are less common causes except in immunocompromised hosts. These cases can be challenging problems for the urologist and a source of substantial morbidity and sometimes mortality for the patients. A variety of modalities of treatment have been described for the management of hemorrhagic cystitis but there is none that is uniformly effective. Some progress has been made in the understanding and management of viral hemorrhagic cystitis. This article reviews the common causes of severe hemorrhagic cystitis and the currently available management options. PMID:20877590

We conducted a retrospective analysis of acute cystitis (AC) patients to evaluate the risk factors of recurrent cystitis (RC) patients following AC. The clinical records of 254 subjects with a confirmed diagnosis of AC and 90 healthy subjects who visited the Health Promotion Center between 2008 and 2012 were reviewed. A patient was diagnosed with RC if she was treated for three or more symptomatic episodes of cystitis over a 12-month period. Results were analyzed according to three groups: normal control (group A, n = 90), AC (group B, n = 121), and RC (group C, n = 133). Women in the cystitis groups (groups B and C) were more likely to have diabetes, be menopausal, have a history of catheterization or sexually transmitted infections (STI), have a low daily water intake, have frequent sexual intercourse, and to use contraception more frequently than the normal control group (P < 0.05). In groups B and C, Escherichia coli was the most common uropathogen, followed by Staphylococcus saprophyticus, Enterococcus species, and Klebsiella species. There were no differences between groups in the detection rates of these uropathogens. Factors that affected progression to RC were diabetes, catheterization history, STI history, sexual intercourse more than four times per month, sexual intercourse in the last month, and the use of contraceptives (P < 0.05). The identification of these factors may help develop preventive, diagnostic, and therapeutic strategies for treating RC that has progressed from AC.

Bladder disorders associated with interstitial cystitis are frequently characterized by increased contractility and pain. The purposes of this study were to examine (1) the effects of blocking mammalian target of rapamycin (mTOR) on the exaggerated bladder activity and pain evoked by cystitis and (2) the underlying mechanisms responsible for the role of mTOR in regulating cystic sensory activity. The expression of p-mTOR, mTOR-mediated phosphorylation of p70 ribosomal S6 protein kinase 1 (p-S6K1), 4 E-binding protein 4 (p-4 E-BP1), as well as phosphatidylinositide 3-kinase (p-PI3K) pathway were amplified in cyclophosphamide rats as compared with control rats. Blocking mTOR by intrathecal infusion of rapamycin attenuated bladder hyperactivity and pain. In addition, blocking PI3K signal pathway attenuated activities of mTOR, which was accompanied with decreasing bladder hyperactivity and pain. Inhibition of either mTOR or PI3K blunted the enhanced spinal substance P and calcitonin gene-related peptide in cyclophosphamide rats. The data for the first time revealed specific signaling pathways leading to cyclophosphamide-induced bladder hyperactivity and pain, including the activation of mTOR and PI3K. Inhibition of these pathways alleviates cystic pain. Targeting one or more of these signaling molecules may present new opportunities for treatment and management of overactive bladder and pain often observed in cystitis. © The Author(s) 2016.

BK virus-associated hemorrhagic cystitis after pediatric stem cell transplantation

2014-01-01

Hemorrhagic cystitis is a common stem cell transplantation-related complication. The incidence of early-onset hemorrhagic cystitis, which is related to the pretransplant conditioning regimen, has decreased with the concomitant use of mesna and hyperhydration. However, late-onset hemorrhagic cystitis, which is usually caused by the BK virus, continues to develop. Although the BK virus is the most common pathogenic microorganism of poststem cell transplantation late-onset hemorrhagic cystitis, pediatricians outside the hemato-oncology and nephrology specialties tend to be unfamiliar with hemorrhagic cystitis and the BK virus. Moreover, no standard guidelines for the early diagnosis and treatment of BK virus-associated hemorrhagic cystitis after stem cell transplantation have been established. Here, we briefly introduce poststem cell transplantation BK virus-associated hemorrhagic cystitis. PMID:25653684

This study aims to investigate the differences in the utilization of healthcare services between patients with bladder pain syndrome/interstitial cystitis (BPS/IC) and patients without using a population-based database in Taiwan. This study comprised of 350 patients with BPS/IC and 1,750 age-matched controls. Healthcare resource utilization was evaluated in the one-year follow-up period as follows: number of outpatient visits and inpatient days, and the mean costs of outpatient and inpatient treatment. A multivariate regression analysis was used to evaluate the relationship between BPS/IC and total costs of health care services. For urological services, patients with BPS/IC had a significantly higher number of outpatient visits (2.5 vs. 0.2, p<0.001) as well as significantly higher outpatient costs ($US166 vs. $US6.8, p<0.001) than the controls. For non-urologic services, patients with BPS/IC had a significantly high number of outpatient visits (35.0 vs. 21.3, p<0.001) as well as significantly higher outpatient cots ($US912 vs. $US675, p<0.001) as compared to the controls. Overall, patients with BPS/IC had 174% more outpatient visits and 150% higher total costs than the controls. Multiple-regression-analyses also showed that the patients with BPS/IC had significantly higher total costs for all healthcare services than the controls. This study found that patients with BPS/IC have a significantly higher number of healthcare related visits, and have significantly higher healthcare related costs than age-matched controls. The high level of healthcare services utilization accrued with BPS/IC was not necessarily exclusive for BPS/IC, but may have also been associated with medical co-morbidities.

Bladder pain syndrome/interstitial cystitis (BPS/IC) is associated with urothelial lesions. Pathomechanisms of urothelial damage and factors for urothelial restoration are unknown. hCG is a factor for cellular differentiation, angiogenesis and immune competence of the endometrium during pregnancy. Clinical observations demonstrate improvement of BPS/IC symptoms during pregnancy or during infertility treatment with hCG. Our research aims were to examine the expression of hCG and luteinizing hormone receptor (LHR) in the urothelium of BPS/IC patients and compare the levels of hCGβ with healthy controls. Bladder biopsies of BPS/IC (CLSM: n = 10; qPCR: n = 15); Tumour-free control tissue from cystectomies (n = 12). hCGα, hCGβ and LHR expression were examined by confocal laser scanning microscopy (CLSM), and hCGβ expression was quantified. hCGβ5 and hCGβ7 mRNA splice variants were quantified in real-time polymerase chain reaction. We found constitutive expression of hCGα, hCGβ and LHR in healthy controls. HCGβ was significantly upregulated in BPS/IC patients in CLSM. PCR analysis revealed higher levels of hCGβ7 than hCGβ5 in controls and BPS/IC patients. The constitutive expression of hCG and LHR speaks in favour for a functional signalling in urothelial cells without any association with either pregnancy or tumour. We show for the first time that hCGβ is upregulated in BPS/IC urothelium and that hCGβ7 is the dominant splice variant in those cells. Our findings imply a major role of hCG for urothelial integrity and a disturbance of hCG signalling in case of BPS/IC. We conclude that hCG could gain therapeutical relevance in the future.

The purpose of this study was to investigate change in bladder capacity as a measure of response to combined intravesical dimethyl sulfoxide (DMSO) and triamcinolone instillations for the treatment of newly diagnosed bladder pain syndrome/interstitial cystitis (BPS/IC). 141 newly diagnosed women were identified retrospectively. 79 were treated with weekly DMSO/triamcinolone instillations. Change in bladder capacity with bladder retrofill, daytime urinary frequency, nocturia episodes per night, and Likert scale symptom scores were reviewed. Wilcoxon signed-rank tests, Wilcoxon rank-sum tests, Spearman's rank correlations, COX regression analysis, and a Kaplan-Meier survival curve were performed. Significant changes (median (25(th)-percentile to 75(th)-percentile) were noted for bladder capacity (75 mL (25 to 130 mL), p < 0.0001), inter-void interval (0 hrs (0 to 1 hour), p < 0.0001), nocturia episodes per night (-1 (-2 to 0), p < 0.0001), and aggregate Likert symptom scores (-2 points (-5 to 0), p < 0.0001). Percent change in bladder capacity correlated positively with percent change in inter-void interval (p = 0.03) and negatively with percent changes in nocturia (p = 0.17) and symptom scores (p = 0.01). Women without detrusor overactivity (DO) had greater percent changes in capacity than women with DO (62.5 % vs. 16.5 %, p = 0.02). 61.3 % of patients were retreated with a 36 weeks median time to retreatment and no difference in time to retreatment based upon DO. Greater capacity was protective against retreatment (hazard ratio = 0.997 [95 % CI 0.994,0.999], p = 0.02). Percent change in bladder capacity is a useful objective measure of response to intravesical DMSO/triamcinolone for newly diagnosed BPS/IC. Clinical outcomes do not differ based upon presence of DO.

Dysregulation of neurotransmitter receptors may contribute to bladder overactivity (OAB) symptoms. To address the question whether specific receptor expression patterns are associated with bladder pain syndrome/interstitial cystitis (BPS/IC), we examined the expression of muscarinic, purinergic and histamine receptors in the detrusor. Detrusor receptor expression was investigated in bladder biopsies of female BPS/IC patients (n = 44; age 60.64 ± 13.78, mean ± SD) and carcinoma patients (n = 11; age 58.91 ± 12.72) undergoing cystectomy. Protein expression of muscarinic (M2, M3), purinergic (P2X1-3) and histamine receptors (H1, H2) was analysed by confocal immunofluorescence, and gene expression was quantified by real-time polymerase chain reaction (qPCR). M2, P2X1, P2X2 and H1 receptor immunoreactivity (-IR) was significantly enhanced in BPS/IC compared to the control group, while there was no difference for M3-, P2X3- and H2-IR. We calculated a score, which separated BPS/IC from control patients with an AUC of 89.46%, showing 84.09% sensitivity and 90.91% specificity. Patients had a 9.25 times enhanced calculated risk for BPS/IC. In addition, two patient subgroups (M2 > M3 and M3 > M2) were observed, which differed in associated purinergic and histamine receptor expression. M2, P2X1, P2X2 and H1 were significantly upregulated in BPS/IC patients, and H2 was occasionally highly overexpressed. There was no significant correlation between receptor protein and gene expression, implying posttranslational mechanisms being responsible for the altered receptor expressions. On the basis of individual receptor profiles, upregulated receptors could be targeted by monotherapy or combination therapy with already approved receptor inhibitors, thereby promoting tailored therapy for patients suffering from BPS/IC-like symptoms.

Advances in Therapeutic Development for Radiation Cystitis.

Radiation treatment for pelvic malignancies is typically associated with radiation injury to urinary bladder that can ultimately lead to radiation cystitis (RC). The late sequelae of radiation therapy may take many years to develop and include bothersome storage symptoms such as hematuria, which may be life-threatening in severe cases of hemorrhagic cystitis. Although no definitive treatment is currently available, various interventions are used for radiation and hemorrhagic cystitis including blood transfusion, bladder irrigation, intravesical instillation of substances such as alum, silver nitrate, prostaglandins or formalin, and fulguration of intravesical bleeding sites and surgery options such as supravesical urinary diversions and cystectomy. Effects of non-surgical treatments for radiation and hemorrhagic cystitis are of modest success and studies are lacking to control the effects caused by RC. When such measures have proven ineffective, use of bladder botulinum toxin injection has been reported. New therapy, such as intravesical immunosuppression with local tacrolimus formulation is being developed for the treatment of radiation hemorrhagic cystitis. © 2013 Wiley Publishing Asia Pty Ltd.

Hemorrhagic cystitis is a potentially life-threatening complication in patients receiving cancer therapy. This urologic emergency is commonly associated with the chemotherapeutic use of oxazaphosphorine alkylating agents. This report describes a case of hemorrhagic cystitis associated with dacarbazine treatment. A 63-year-old man with asymptomatic metastatic malignant melanoma received 3 cycles of dacarbazine (600-850 mg/m2) monochemotherapy, each 3 weeks apart. Two weeks after the third cycle, he presented with gross hematuria and mild dysuria. Physical examination revealed no significant finding. Hematuria was confirmed by urinalysis, and urinary infection was excluded by repeated urine cultures. Ultrasonography revealed diffuse bladder wall thickening with no discrete mass or ulceration. Cystoscopy findings revealed generalized inflammation and edema of the mucosa of the bladder, confirming the diagnosis of hemorrhagic cystitis. The patient's gross hematuria continued for 2 weeks and then completely resolved with supportive care. Two weeks after complete resolution, the patient experienced 2 transient episodes of gross hematuria that lasted a few hours and subsided spontaneously. Dacarbazine is currently considered the standard first-line treatment in patients with advanced malignant melanoma. At standard prescribed doses (a single dose of 850-1000 mg/m2 or 250 mg/m2 for 5 days per cycle), dacarbazine is a reasonably well tolerated chemotherapeutic drug; nausea, vomiting, and myelosuppression are the most common adverse effects. Association of dacarbazine with hemorrhagic cystitis has not been reported previously (in a PubMed literature search from 1950-2006), and only 1 case report associates temozolomide (an analog of dacarbazine) with hemorrhagic cystitis. Based on the Naranjo adverse drug reactions probability scale, an objective assessment revealed dacarbazine to be a probable cause of hemorrhagic cystitis in this case. This case report suggests that

Emphysematous cystitis: a rare cause of gross hematuria.

Emphysematous cystitis is a relatively rare infectious condition of the urinary bladder. The mortality rate is high if the diagnosis is delayed or if the treatment is inadequate. We present an uncommon case of emphysematous cystitis and highlight the risk factors for this disease. An 81-year-old man with a past medical history of type 2 diabetes and a central pontine infarction presented to the Emergency Department due to gross hematuria. Computed tomography (CT) and plain radiography revealed localized gas within the bladder that was compatible with the diagnosis of emphysematous cystitis. A Foley catheter was inserted. Urine culture grew Klebsiella pneumoniae; 2 g cefotaxime daily was initiated. Subsequent plain radiography and CT scan showed regression of intraluminal gas. We recommend CT for the definitive diagnosis of emphysematous cystitis. Adequate antibiotic therapy, strict blood glucose control, adequate drainage of urine, and early goal-directed therapy for suspected sepsis are suggested to prevent the complications of emphysematous cystitis.

To investigate the efficacy of low dose triamcinolone injection for effectiveness and durability in interstitial cystitis/bladder pain syndrome (IC/BPS) patients with Hunner Lesions (HL). Clinical data from patients with HL who underwent endoscopic submucosal injection of triamcinolone were reviewed: Demographics, pre/post operative pain and nocturia scores, and long-term clinical outcomes were assessed. Duration of response was estimated by time to repeat procedure. Kaplan-Meier estimator was used to evaluate time to repeat procedure. 36 patients who received injections of triamcinolone between 2011 and 2015 were included. Median age±SD of patients was 61.5±12.0 years 23; 28 (77.8%) of patients were female and 8 (22.2%) were male. 26 patients (72.2%) received only 1 set of injections, 8 (22.2%) received 2 sets of injections, and 2 (5.56%) received 3 or more sets of injections. Average time between injections in those receiving more than one set of injections was 344.9 days (median: 313.5, range: 77-714). Pre-procedural pain scores were 8.3±1.2 (mean±SD) on Likert pain scale (0-10), and mean post-procedural pain scores at approximately one month were 3.8±2.2 p<0.001. Mean pre-procedural nocturia bother scores were 7.5±2.0 and mean post-procedural nocturia bother scores were 5.1±2.5) p<0.001. Endoscopic submucosal injection of low dose triamcinolone in IC/BPS patients with HL is an effective and durable adjunct to existing treatment modalities. This approach is associated with low morbidity and can be performed on an outpatient basis. Copyright © 2018. Published by Elsevier Inc.

To investigate the incidence and risk factors associated with persistent urinary frequency, and to evaluate the efficacy of antimuscarinic treatment. Interstitial cystitis/bladder pain syndrome (IC/BPS) patients complaining of persistent urinary frequency despite improved pain were evaluated. Before initial conventional treatment, each patient completed a voiding diary and symptom questionnaires. After conventional treatment, patients were divided according to the presence of pain and frequency. Improved pain was defined as lesser than 3 points in visual analogue scale, and persistent urinary frequency as >10 times/d. Risk factors for persistent frequency were identified through multivariate analysis. The efficacy of antimuscarinic treatment was assessed by the mean change of frequency. Of 171 IC/BPS patients treated with conventional therapy, 132 had improved pain after 3 months, but 72 had persistent frequency (72 of 132, 54.5%). Patients with persistent frequency had lower voided volume (p=0.008), lower maximal flow rate (p<0.001), lower maximal bladder capacity (p=0.003), and more frequent micturition (p<0.001) at baseline compared to those with improved frequency. Patients who took antimuscarinic agents showed slightly decreased urinary frequency, from 14.6 times/d to 13.5 times/d (p=0.438) after 3 months of medication. No patients showed more than a 20% decrease in frequency with antimuscarinics. About half of the patients with IC/BPS showed persistent frequency, with poor voiding function identified as a risk factor; antimuscarinic treatment was not effective in these patients.

Interstitial cystitis (IC), also known as painful bladder syndrome (PBS), is a debilitating chronic condition that afflicts over 3 million women above the age of 18 in the U.S., and most patients fail to respond to current treatment options. Mast cells have previously been implicated as both a diagnostic and prognostic marker in IC/PBS. Patients with IC/PBS have been shown to have elevated levels of IL-33, a cytokine released in response to tissue insult, in their urine. We hypothesize that mast cell-mediated inflammation induced from IL-33 may play an important role in initiating pain and inflammation in IC/PBS. A human cathelicidin, LL-37, which is found at elevated levels in IC/PBS patients, was used to induce an IC/PBS-like state of inflammation and bladder pain in mast cell deficient C-kit (-/-) and wild type C57Bl/6 (WT) mice. Inflammation was quantified using myeloperoxidase (MPO) expression in bladder tissues measured via ELISA. Response rate to suprapubic stimulation from von Frey filaments was used to assess the relative pain and discomfort. Both types of mice increased IL-33 expression in response to LL-37 exposure. However, mast cell deficient mice demonstrated significantly lower levels of inflammation (p < 0.001) and reduced pain response (p < 0.001) compared to WT mice. These findings implicate an IL-33-mast cell dependent axis with a potential etiology of pain and inflammation in IC/PBS. Future therapeutics aimed at targeting the IL-33 - mast cell axis could potentially serve as useful targets for treating IC/PBS. Copyright © 2018. Published by Elsevier Ltd.

To study the correlation between polyoma virus load and hemorrhagic cystitis after allogeneic stem cells transplantation for prevention of hemorrhagic cystitis. Blood and urine specimens were collected from 40 healthy persons, 40 patient with stem cells transplantation and 20 cases complicated with hemorrhagic cystitis for determination of VP1 gene of polyomaviruses BK virus (BKV)/Jamestown Canyon virus (JCV) and simian virus 40 (SV40) by polymerase chain reaction (PCR) and EvaGreen stain fluorescence quantitative assay. In the peripheral blood, all genes of BKV/JCV and SV40 were negative, while BKV gene in urine and blood from healthy persons and patient with stem cells transplantation was 15% (6/40) and 100% (40/40), respectively. The gene of JCV was positive in 10% (4/40) and 12% (5/40), the gene of SV40 was negative. Genes of BKV and JCV was detectable in urine specimens of healthy persons and there was a correlation between the load of polyomavirus and incidence of hemorrhagic cystitis.

To investigate the changes including expression and localization of 2 potassium channels, renal outer medullary K + channel (ROMK) and voltage-gated K + channel 7.1 (KCNQ1), after increased urinary potassium leakage in patients with interstitial cystitis/painful bladder syndrome (IC/PBS). The study group included 24 patients with IC/PBS and a control group consisting of 12 volunteers without any IC/PBS symptoms. Bladder biopsies were taken from both groups. We determined the protein expression and distribution of potassium channels using immunoblotting, immunohistochemistry, and immunofluorescent staining under confocal laser microscopy. The results revealed that ROMK was predominantly expressed in apical cells of the bladder urothelium at significantly higher levels (3.3-fold) in the study group than in the control group. In contrast, KCNQ1 was expressed in the basolateral membrane according to confocal microscopy results and did not significantly differ between groups. Our data showed that the abundance of ROMK protein in apical cells was increased in the IC/PBS group, whereas KCNQ1, which was distributed in the basolateral membrane of the bladder urothelium, showed similar abundance between groups. These results suggest that upregulation of the ROMK channel in apical cells might permit avid potassium flux into the bladder lumen to maintain intracellular K + homeostasis in the dysfunctional urothelium.

This study was performed to investigate the clinical characteristics of lupus cystitis and determine the risk factors and clinical outcomes of lupus cystitis in patients with systemic lupus erythematosus (SLE). We retrospectively reviewed 1064 patients at Seoul St. Mary's Hospital in Seoul, Korea, from 1998 to 2013. Twenty-four patients had lupus cystitis. Lupus cystitis was defined as unexplained ureteritis and/or cystitis as detected by imaging studies, cystoscopy, or bladder histopathology without urinary microorganisms or stones. Three-fourths of patients with lupus cystitis had concurrent lupus mesenteric vasculitis (LMV). The initial symptoms were gastrointestinal in nature for most patients (79.2%). High-dose methylprednisolone was initially administered to most patients (91.7%) with lupus cystitis. Two patients (8.3%) died of urinary tract infections. Sixty-five age- and sex-matched patients with SLE who were admitted with other manifestations were included as the control group. Patients with lupus cystitis showed a lower C3 level (p = 0.031), higher SLE Disease Activity Index score (p = 0.006), and higher ESR (p = 0.05) upon admission; more frequently had a history of LMV prior to admission (p < 0.001); and less frequently had a history of neuropsychiatric lupus (p = 0.031) than did patients with SLE but without lupus cystitis. The occurrence of lupus cystitis was associated with a history of LMV (OR, 21.794; 95% CI, 4.061-116.963). The median follow-up period was 3.4 years, and the cumulative one-year mortality rate was 20%. Complications developed in 33.3% of patients with lupus cystitis and were related to survival (log-rank p = 0.021). Our results suggest that the possibility of lupus cystitis should be considered when a patient with SLE and history of LMV presents with gastrointestinal symptoms or lower urinary tract symptoms. Development of complications in patients with lupus cystitis can be fatal. Thus, intensive treatment

Intravesical application of an anti-inflammatory drug is an efficient strategy for acute cystitis therapy. Quercetin (QU) is a potent anti-inflammatory agent; however, its poor water solubility restricts its clinical application. In an attempt to improve water solubility of QU, biodegradable monomethoxy poly(ethylene glycol)-poly(ɛ-caprolactone) (MPEG-PCL) micelles were used to encapsulate QU by self-assembly methods, creating QU/MPEG-PCL micelles. These QU/MPEG-PCL micelles with DL of 7% had a mean particle size of <34 nm, and could release QU for an extended period in vitro. The in vivo study indicated that intravesical application of MPEG-PCL micelles did not induce any toxicity to the bladder, and could efficiently deliver cargo to the bladder. Moreover, the therapeutic efficiency of intravesical administration of QU/MPEG-PCL micelles on acute cystitis was evaluated in vivo. Results indicated that QU/MPEG-PCL micelle treatment efficiently reduced the edema and inflammatory cell infiltration of the bladder in an Escherichia coli-induced acute cystitis model. These data suggested that MPEG-PCL micelle was a candidate intravesical drug carrier, and QU/MPEG-PCL micelles may have potential application in acute cystitis therapy. PMID:22661886

Anterior vaginal wall tenderness (AVWT) as a physical symptom in chronic pelvic pain.

Paulson, John D; Paulson, Joseph N

2011-01-01

Chronic pelvic pain is often difficult to diagnose and treat properly. Physicians called on to treat this problem may not be able to give a specific diagnosis. The aim of this study was to see whether the physical presence of anterior vaginal wall tenderness could help narrow down and elucidate diagnoses in a practice focusing on diagnosis and treatment of chronic pelvic pain. The study cohort comprised 284 patients with chronic pelvic pain limited to gynecologic and lower urinary problems. Histories, physical examinations, and endoscopic procedures were performed on each patient. An analysis of this information was conducted. Of the chronic pelvic pain patients, 78% had endometriosis, 81% had interstitial cystitis, and 61% had both concurrently. The sensitivity of anterior vaginal wall tenderness (AVWT) in patients with interstitial cystitis was 95%, and in those with only endometriosis and no interstitial cystitis, the sensitivity was 17%. The positive predictive value for interstitial cystitis was 85%, and for endometriosis it was 67%. Examination of the anterior vaginal wall with an empty bladder at the initial examination can lead one to suspect interstitial cystitis and possibly either concomitant or singular endometriosis and allow the physician to approach the workup accordingly.

BK virus is associated with hemorrhagic cystitis after hematopoietic stem cell transplantation (HSCT), although evidence supporting a causal relationship remains limited. Although BK viruria is common after HSCT, BK viremia may better predict clinically significant cystitis, similar to its predictive value for nephropathy after kidney transplantation. We hypothesized that BK viremia would precede hemorrhagic cystitis in a cohort of 88 consecutive children prospectively enrolled to originally study thrombotic microangiopathy in the first 100 days after allogeneic HSCT. Cox regression models with time-varying covariates assessed the association between different BK viremia cutoffs and the development of hemorrhagic cystitis, defined as at least macroscopic hematuria. Subjects with a peak plasma BK viral load 1 to 9999 copies/mL had an adjusted hazard ratio of 4.2 (95% confidence interval (CI), 1.3 to 13.7) for the development of hemorrhagic cystitis. Those with peak BK viremia >100,000 copies/mL had an adjusted hazard ratio of 116.8 (95% CI, 12 to 1136) for cystitis. Other independent risk factors for hemorrhagic cystitis included age >7 years and HHV-6 viremia. Neither graft-versus-host disease nor achieving engraftment increased the risk for cystitis. If therapeutic strategies are found to be effective, these observations may support screening for BK viremia after HSCT, as currently recommended for other DNA viruses. PMID:23665115

Weiss, J.P.; Boland, F.P.; Mori, H.

The effects of hyperbaric oxygen on radiation cystitis have been documented in 3 patients with radiation-induced hemorrhagic cystitis refractory to conventional therapy. Cessation of gross hematuria and reversal of cystoscopic bladder changes were seen in response to a series of hyperbaric oxygen treatments of 2 atmosphere absolute pressure for 2 hours. To our knowledge this is the first report of cystoscopically documented healing of radiation-induced bladder injury.

To characterize the nature and impact of sleep disturbances on quality of life (QOL) in women with interstitial cystitis/bladder pain syndrome (IC/BPS). Participants were 3,397 women from a telephone probability survey who met IC/BPS symptom criteria. Sleep quality, duration, and IC/BPS nocturnal symptoms (i.e., trouble sleeping due to bladder pain, urgency, or needing to use the bathroom), general QOL (mental and physical health and sexual functioning), and IC/BPS QOL impairment were assessed via self-report during telephone interview. Over half of the sample reported poor sleep quality, sleep duration ≤ 6 hours, or trouble sleeping due to IC/BPS symptoms. After covariate adjustment, short sleep duration was significantly associated with greater IC/BPS QOL impairment (β = -0.04; p < 0.001) and poorer self-reported physical health (β = 1.86; p < 0.001). Poor sleep quality was significantly associated with greater IC/BPS QOL impairment (β = 0.06; p < 0.001), poorer self-reported physical health (β = -2.86; p < 0.001), and greater sexual dysfunction (β = -0.04; p < 0.05). IC/BPS nocturnal symptoms were significantly associated with greater IC/BPS impairment (β = 0.14; p < 0.001), poorer physical health (β = -2.76; p < 0.001) and mental health (β = 0.52; p < 0.01), and greater sexual dysfunction (β = -0.10; p < 0.001), after covariate adjustment. After further adjustment for IC/BPS nocturnal symptoms, we found that poor sleep quality and short sleep duration were independent correlates of poor self-reported physical health. Poor sleep quality and short sleep duration, as well as disorder-specific sleep disturbances, are highly prevalent in women with IC/BPS and are associated with poorer disease-specific and general QOL. © 2014 American Academy of Sleep Medicine.

Cyclophosphamide and its derivatives induce hemorrhagic cystitis. A substantial number of patients receive bladder augmentation or replacements using bowel. If patients who have undergone colocystoplasty need treatment with cyclophosphamide before or after the operation, does hemorrhagic cystitis develop? We evaluated the histological changes produced in the colon wall and bladder related to cyclophosphamide and its derivatives in rats that underwent colocystoplasty. Sprague-Dawley rats of each sex were grouped according to whether they received a single 200 mg./kg. dose of cyclophosphamide, underwent colocystoplasty, underwent each technique or served as controls. The technique of colocystoplasty was the same in all groups. Results were analyzed according to previously reported criteria, by the gross appearance of the bladder and colon segment used for colocystoplasty, and by histological changes. Two weeks after surgery colocystoplasty had not resulted in secondary changes in the implanted colon segment or original bladder, while there were only nonspecific changes of an inflammatory type in the anastomotic area. After cyclophosphamide administration the animals lost considerable weight and in the bladder area we observed hemorrhagic cystitis that was greater in males than in females, and greater in isolated bladder than when the bladder was sutured to the colon segment. In the colon there was no inflammation or hemorrhage damage of the hemorrhagic cystitis type in the bladder. A total of 12 days after colocystoplasty there were no secondary histological changes except in the anastomotic area. A single 200 mg./kg. dose of cyclophosphamide caused substantial weight loss and hemorrhagic cystitis. Cystitis was quantitatively greater in males than in females and greater in isolated bladder than in bladder anastomosed to the colon. Administering a single dose of cyclophosphamide did not result in lesions in the colon segment used for colocystoplasty analogous to those

An 8-year-old intact male Persian cat was presented for investigation of chronic haematuria. The cat had episodes of haematuria on several occasions that were non-responsive to antimicrobial therapy. Abdominal ultrasound examination revealed dilation of the renal pelvis and ureters of both kidneys. The urinary bladder wall was thickened, a mass of heterogeneous echogenicity filled the lumen of the bladder, and two parallel thin hyperechoic lines were identified within the lumen, which suggested a urethral catheter. Differential diagnoses for the urinary bladder mass included cystitis and neoplasia. The mass was surgically removed from the urinary bladder, and a urethral catheter was found embedded in the mass. Histopathological findings were consistent with cystitis glandularis of a typical type. Periodic bladder ultrasonographic studies were performed; at the time of writing, over 2 years later, recurrence had not been detected.

Biomarker discovery is limited by readily assessable, cost efficient human samples available in large numbers that represent the entire heterogeneity of the disease. We developed a novel, active participation crowdsourcing method to determine BP-RS (Bladder Permeability Defect Risk Score). It is based on noninvasive urinary cytokines to discriminate patients with interstitial cystitis/bladder pain syndrome who had Hunner lesions from controls and patients with interstitial cystitis/bladder pain syndrome but without Hunner lesions. We performed a national crowdsourcing study in cooperation with the Interstitial Cystitis Association. Patients answered demographic, symptom severity and urinary frequency questionnaires on a HIPAA (Health Insurance Portability and Accountability Act) compliant website. Urine samples were collected at home, stabilized with a preservative and sent to Beaumont Hospital for analysis. The expression of 3 urinary cytokines was used in a machine learning algorithm to develop BP-RS. The IP4IC study collected a total of 448 urine samples, representing 153 patients (147 females and 6 males) with interstitial cystitis/bladder pain syndrome, of whom 54 (50 females and 4 males) had Hunner lesions. A total of 159 female and 136 male controls also participated, who were age matched. A defined BP-RS was calculated to predict interstitial cystitis/bladder pain syndrome with Hunner lesions or a bladder permeability defect etiology with 89% validity. In this novel participation crowdsourcing study we obtained a large number of urine samples from 46 states, which were collected at home, shipped and stored at room temperature. Using a machine learning algorithm we developed BP-RS to quantify the risk of interstitial cystitis/bladder pain syndrome with Hunner lesions, which is indicative of a bladder permeability defect etiology. To our knowledge BP-RS is the first validated urine biomarker assay for interstitial cystitis/bladder pain syndrome and one of the

Background: We investigated whether extracorporeal shock wave (ECSW) therapy can attenuate cyclophosphamide (CYP)-induced acute interstitial cystitis (AIC) in rats. Methods and Results: Eighteen male-adult Sprague-Dawley rats were equally divided into group 1 (sham control), group 2 (AIC induced by 150 mg/kg CYP by intra-peritoneal injection) and group 3 (AIC + ECSW 200 impulses at 0.11 mJ/mm2 to the urinary bladder at 3 and 24 h after CYP treatment). Smooth-muscle cells co-culture with menadione (25 µM) with and without ECSW treatment was performed. Western-blot results demonstrated that ECSW significant attenuated oxidative stress and inflammatory reactions in this in-vitro studies (all p < 0.001). 24-hour urine amount and microscopic findings of red-blood-cell count (i.e., hematuria) were higher in group 2 than in groups 1 and 3, and significantly higher in group 3 than in group 1 (all p < 0.001). The urine levels of albumin and interleukin-6 showed an identical pattern of hematuria among all three groups (all p < 0.001). The cellular and mRNA expressions of macrophage migration inhibitory factor (MIF)+, CD74+, CD68+, substance p+, and Cox-2+ cells in the bladder tissue exhibited an identical pattern of hematuria among all groups (all p < 0.0001). The integrity of epithelial layer and collagen-deposition area as stained by Sirius red displayed an opposite pattern of hematuria among the three groups (p < 0.0001). The protein expression of IL-12, iNOS, TNF-α, NF-κB, MMP-9, NOX-1, NOX-2, RANTES, and Oxyblot displayed an identical pattern of hematuria among all groups (all p < 0.01). Conclusion: ECSW therapy markedly attenuated CYP-induced AIC through inhibitions of the inflammation and oxidative stress. PMID:25628776

Background Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a condition characterized by pelvic pain and urinary symptoms. Some IC/BPS patients have pain confined to the pelvic region, while others suffer widespread pain. Inflammatory processes have previously been linked to pelvic pain in IC/BPS, but their association with widespread pain in IC/BPS has not been characterized. Methods Sixty-six women meeting criteria for IC/BPS completed self-report measures of pain as part of the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP), collected 3 days of saliva for cortisol assays, and provided blood samples. Peripheral blood mononuclear cells (PBMCs) were stimulated with Toll-Like Receptor (TLR) 2 and 4 agonists and cytokines were measured in supernatant; IL-6 was also measured in plasma. Associations between inflammatory variables and the likelihood of endorsing extra-pelvic pain, or the presence of a comorbid syndrome, were tested by logistic regression and General Linear Models, respectively. A subset of patients (n=32) completed Quantitative Sensory Testing. Results A one standard deviation increase in TLR-4 inflammatory response was associated with a 1.59 greater likelihood of endorsing extra-pelvic pain (p = .019). Participants with comorbid syndromes also had higher inflammatory responses to TLR-4 stimulation in PBMCs (p = .016). Lower pressure pain thresholds were marginally associated with higher TLR-4 inflammatory responses (p = .062), and significantly associated with higher IL-6 in plasma (p = .031). Conclusions TLR-4 inflammatory responses in PBMCs are a marker of widespread pain in IC/BPS, and should be explored in other conditions characterized by medically unexplained pain. PMID:25771510

Acute cystitis refers to uncomplicated lower urinary tract infections, with the recurrence rates after the first cystitis episode being 50%. The basic treatment for the above diseases is antibacterial therapy, whose efficiency depends entirely on the right choice of a drug during initial empiric therapy. The paper gives the European Association of Urology guidelines and Russian guidelines, which are based on the results of both international (ARESC) and Russian (DARMIS) studies of urinary tract infection pathogens and their susceptibility to antibacterial drugs. Phosphomycin trometamol and furasidine potassium are the drugs of choice to treat acute cystitis in Russia now.

Interstitial cystitis/bladder pain syndrome (IC/BPS) has several well-known comorbid psychiatric manifestations, including insomnia, anxiety, and depression. We hypothesized that somatoform disorder, which is a psychosomatic disease, can be used as a sensitive psychiatric phenotype of IC/BPS. We investigated whether somatoform disorder increases the risk of IC/BPS.A nested case-control study and a retrospective cohort study were followed up over a 12-year period (2002-2013) in the Taiwan Health Insurance Reimbursement Database. In the nested case-control study, 1612 patients with IC/BPS were matched in a 1:2 ratio to 3224 controls based on propensity scores. The odds ratio for somatoform disorder was calculated using conditional logistic regression analysis. In the retrospective cohort study, 1436 patients with somatoform disorder were matched in a 1:2 ratio to 2872 patients with nonsomatoform disorder based on propensity scores. Cox regression analysis was used to estimate the hazard ratio associated with the development of IC/BPS in patients with somatoform disorder, and the cumulative survival probability was tested using the Kaplan-Meier analysis.We found that the odds ratio for somatoform disorder was 2.46 (95% confidence interval [CI], 1.05-5.76). Although the average time until IC/BPS development in the control subjects was 11.5 ± 1.3 years, this interval was shorter in patients with somatoform disorder (6.3 ± 3.6 years). The hazard ratio for developing IC/BPS was 2.50 (95% CI 1.23-5.58); the adjusted hazard ratio was 2.26 (95% CI 1.002-5.007). The patients and controls also differed significantly in their cumulative survival probability for IC/BPS (log rank P < .05).Evidence from the nested case-control study and retrospective cohort study consistently indicated that somatoform disorder increases the risk for IC/BPS. Our study suggests that somatoform disorder can be used as a sensitive psychiatric phenotype to predict IC/BPS. Any past history

Thirty-five patients, 38 to 88 years of age, were treated with 125-Iodine or 192-Iridium interstitial implants at Stanford University Medical Center between July 1974, and December, 1978. There were 25 primary epithelial malignancies, eight extensions from intrapelvic organs and two metastatic tumors (hypernephroma and Hodgkin's disease). The involved sites were: urethra (6 patients); vulva (9 patients); vagina (8 patients); anus (7 patients); cervix (5 patients). Implantation was usually performed to treat evident or microscopic disease in conjunction with external beam pelvic treatment with or without local excision. Computerized implant preplanning was used.125-Iodine seeds were inserted either directly or within absorbablemore » suture Polyglactin 910; 192-Iridium in nylon carriers was placed by suture or transperineal template. Two patients were lost to follow-up leaving 33 patients, 27 of whom are alive and free of local disease from 37 to 76 months. The overall local control rate was 88%, or 29/33 patients. All four local recurrences appeared before 24 months. Minor complications included: 10 patients with transient mucositis, four with superficial ulcers, and one patient with infection at the implanted site. Two major complications occurred: a necrotic rectal ulcer requiring a colostomy and a contracted, painful bladder necessitating a urinary diversion. It is concluded that in selected cases interstitial irradiation provides good local control of perineal and gynecological malignancies with low morbidity in this elderly and quite often fragile group of patients.« less

Eosinophilic cystitis with recurrent urinary retention: case report.

2017-01-01

Eosinophilic cystitis is a rare inflammatory disease of the bladder whose origin, pathogenesis, and treatment are unknown. Frequency, dysuria, and hematuria are frequent symptoms. Here, we report a rare occurrence of recurrent urinary retention and repetitive catheterization. A 67-year-old male presented with acute urinary retention and intermittent gross hematuria of 2 weeks duration. Urethral catheterization followed by a trial without catheter, was successful. Complete blood count showed presence of eosinophils (eosinophilia) and computed tomography of kidneys, ureter and bladder with contrast showed thickened bladder wall and small prostate. Cystoscopy revealed an erythematous lesion over the anterior wall. The rest of the mucosa was normal. Transurethral biopsies of the lesion were performed and histologic examination showed features of eosinophilic cystitis. Despite multiple medication regimens containing corticosteroids and antihistamines, he presented with recurrent urinary retention, approximately once every month. After 6 months, he was started on bethanechol, which led to no catheterization for up to 2 years. To the best of our knowledge, this is the first report on the successful use of bethanechol as a treatment for eosinophilic cystitis with recurrent urinary retention.

Research performed in the late 1960s, using 24Na, suggested that the perfusion of skin and subcutaneous tissues is critically dependent on the relationship between capillary (Pc) and tissue pressures (Pt). Perfusion changes differed significantly between controls and patients with venous disease and the differences could be interpreted as evidence that Pt remained high in venous diseased patients. From this starting point, a biomechanical theory for the aetiology of venous ulceration was developed and tested by measuring skin elasticity, limb cross-sectional area and laser Doppler flux. The results confirm that, modelled as a two-compartment system (vascular and interstitial fluid), forces can be demonstrated sufficient to cause intermittent capillary closure and subsequent reperfusion injury. These forces are maximal in the gaiter area, the site of most leg ulcers. Images Figure 2 Figure 4 PMID:10364960

CASE DESCRIPTION AS-year-old male Dwarf rabbit and 4-year-old female Mini-Rex rabbit were evaluated because of anorexia and urine scalding of the perineum. CLINICAL FINDINGS Abdominal radiography revealed a diffuse increase in the opacity of the urinary bladder attributable to urinary sludge. In 1 rabbit, abdominal ultrasonography revealed several mass-like lesions protruding from the mucosal surface into the lumen of the urinary bladder. Rabbits were anesthetized, and cystoscopy was performed with a rigid 2.7-mm, 30° endoscope. Histologic analysis of tissue samples obtained through the cystoscope operating channel revealed findings consistent with polypoid cystitis. TREATMENT AND OUTCOME To remove the urinary sludge from each rabbit, the urinary bladder was filled with sterile saline (0.9% NaCl) solution and emptied with a gentle massage several times until the ejected fluid was transparent. Rabbits were treated with NSAIDs, antimicrobials (chosen following microbial culture of urine and antimicrobial susceptibility testing), bathing of the perineum, and a low-calcium diet. The male rabbit died of unrelated causes 18 months later; postmortem examination findings confirmed the polypoid cystitis. The female rabbit remained disease free through to last follow-up (12 months after initial evaluation). CLINICAL RELEVANCE This was the first report of polypoid cystitis in pet rabbits. Although ultrasonographic findings supported this diagnosis, a definitive diagnosis was achieved through cystoscopy and lesion biopsy. Treatments administered were intended to reduce the potential sources of irritation. Research is needed to investigate the effectiveness of the applied interventions and the association between excessive urinary calcium excretion and polyploid cystitis in rabbits.

Weiss, J.P.; Neville, E.C.

Of 8 patients with symptoms of advanced cystitis due to pelvic radiation treated with hyperbaric oxygen 7 are persistently improved during followup. All 6 patients treated for gross hematuria requiring hospitalization have been free of symptoms for an average of 24 months (range 6 to 43 months). One patient treated for stress incontinence currently is dry despite little change in bladder capacity, implying salutary effect from hyperbaric oxygen on the sphincter mechanism. One patient with radiation-induced prostatitis failed to respond. This experience suggests that hyperbaric oxygen should be considered the primary treatment for patients with symptomatic radiation-induced hemorrhagic cystitis.

BACKGROUND The cause of acute uncomplicated cystitis is determined on the basis of cultures of voided midstream urine, but few data guide the interpretation of such results, especially when gram-positive bacteria grow. METHODS Women from 18 to 49 years of age with symptoms of cystitis provided specimens of midstream urine, after which we collected urine by means of a urethral catheter for culture (catheter urine). We compared microbial species and colony counts in the paired specimens. The primary outcome was a comparison of positive predictive values and negative predictive values of organisms grown in midstream urine, with the presence or absence of the organism in catheter urine used as the reference. RESULTS The analysis of 236 episodes of cystitis in 226 women yielded 202 paired specimens of midstream urine and catheter urine that could be evaluated. Cultures were positive for uropathogens in 142 catheter specimens (70%), 4 of which had more than one uropathogen, and in 157 midstream specimens (78%). The presence of Escherichia coli in midstream urine was highly predictive of bladder bacteriuria even at very low counts, with a positive predictive value of 102 colony-forming units (CFU) per milliliter of 93% (Spearman’s r = 0.944). In contrast, in midstream urine, enterococci (in 10% of cultures) and group B streptococci (in 12% of cultures) were not predictive of bladder bacteriuria at any colony count (Spearman’s r = 0.322 for enterococci and 0.272 for group B streptococci). Among 41 episodes in which enterococcus, group B streptococci, or both were found in midstream urine, E. coli grew from catheter urine cultures in 61%. CONCLUSIONS Cultures of voided midstream urine in healthy premenopausal women with acute uncomplicated cystitis accurately showed evidence of bladder E. coli but not of enterococci or group B streptococci, which are often isolated with E. coli but appear to rarely cause cystitis by themselves.

This manuscript aims to address the evidence availale in the literature on the efficacy of Botulinum Toxin A (BoNT-A) and sacral neuromodulation (SNM) in patients suffering from Interstitial Cystitis (IC)/BPS and propose further research to identify mechanisms of action and establish the clinical efficacy of either therapy. At the International Consultation on Incontinence-Research Society (ICI-RS) in 2017, a panel of Functional Urologists and Urogynaecologists participated in a Think Tank (TT) discussing the management of IC/BPS by BoNT-A and SNM, using available data from both PubMed and Medicine literature searches. The role of BoNT-A and SNM in the treatment of IC/BPS are discussed and mechanisms of actions are proposed. Despite the available randomized trial data on the effect of intravesical BoNT-A treatment on symptoms of IC/BPS, a consistent conclusion of a positive effect cannot be drawn at the moment, as the published studies are small and heterogeneous in design. There is substantive evidence for the positive effects of SNM on symptoms of IC/BPS patients however, during patient selection, it is important to distinguish the degree and the location of pain in order to tailor the best therapy to the right patients. Both intravesical BoNT-A treatment and SNM have been shown to have positive effects in patients with IC/BPS. However, firm conclusions cannot yet be drawn. Patient-reported outcomes and quality of life should be assessed in addition to urinary and pain symptoms. Since current treatments mainly focus on symptomatic relief, future research should also focus on clarifying the pathogenic mechanisms involved in IC/BPS. © 2018 Wiley Periodicals, Inc.

Hematopoietic stem cell transplant recipients frequently develop BK virus (BKV)-associated hemorrhagic cystitis, which coincides with BK viruria. However, the precise role of BKV in the etiology of hemorrhagic cystitis in hematopoietic stem cell transplant recipients remains unclear, since approximately 50% of all such adult transplant recipients excrete BKV, yet do not develop this clinical condition. In the present study, BKV were analyzed to determine if mutations in the non-coding control region (NCCR), and specific BKV sub-types defined by sequence analysis of major capsid protein VP1, were associated with development of hemorrhagic cystitis in hematopoietic stem cell transplant recipients. The regions encoding VP1 and NCCRs of BKV in urine samples collected from 15 hematopoietic stem cell transplant recipients with hemorrhagic cystitis and 20 without this illness were amplified and sequenced. Sequence variations in the NCCRs of BKV were identified in urine samples from those with and without hemorrhagic cystitis. Furthermore, five unique sequence variations within transcription factor binding sites in the canonical NCCR, O-P-Q-R-S, were identified, representing new BKV variants from a population of cloned quasi-species obtained from patients with and without hemorrhagic cystitis. Thirty-five BKV VP1 sequences were analyzed by phylogenetic analysis but no specific BKV sub-type was associated with hemorrhagic cystitis. Five previously unrecognized naturally occurring variants of the BKV are described which involve amplifications, deletions, and rearrangements of the archetypal BKV NCCRs in individuals with and without hemorrhagic cystitis. Architectural rearrangements in the NCCRs of BKV did not appear to be a prerequisite for development of hemorrhagic cystitis in hematopoietic stem cell transplant recipients.

To evaluate and compare the ocular surface condition in herpetic interstitial stromal keratitis and neurotrophic ulcer groups and their normal fellow eyes. In this observational, cross-sectional case-control study, 85 consecutive patients were included, including 56 cases of treated herpetic interstitial keratitis and 29 patients with neurotrophic ulcers. Fifty-six age- and sex-matched participants were also recruited from a normal population as the control group. We evaluated and scored the subjective and objective measures of dry eye for both eyes of all patients. Then, we compared the score of the groups with one another and also with the control group. The main outcome measures were the discomfort level, visual symptoms of dry eye, conjunctival injection, conjunctival staining, corneal staining, corneal tear signs of dry eye, meibomian gland dysfunction, tear break-up time, Schirmer test score with anesthesia, and tear osmolarity. The normal fellow eye of the herpetic keratitis group had significantly higher discomfort levels (1.4 ± 0.9 vs. 1.3 ± 0.5, P = 0.003), visual symptoms (1.7 ± 0.8 vs. 1.3 ± 0.7, P = 0.002), tear break-up time (8.3 ± 3.2 vs. 12.1 ± 3.3 seconds, P = 0.003), Schirmer test scores (9.2 ± 3.9 vs. 12.9 ± 3 mm, P = 0.04), and tear osmolarity (9.2 ± 3.9 vs. 12.9 ± 3 mm, P = 0.003) in comparison with normal controls. The normal fellow eyes of the neurotrophic ulcer group had significantly worse values for discomfort level (1.9 ± 0.9 vs. 1.3 ± 0.5, P < 0.001), tear break-up time (7.9 ± 4 vs. 12.1 ± 3.3, P = 0.004), Schirmer test score (8.1 ± 3.9 vs. 12.9 ± 3, P = 0.005), and tear osmolarity (295 ± 9.2 vs. 292.7 ± 5.9, P = 0.02) compared with normal controls. Both eyes of patients with neurotrophic ulcer and interstitial herpetic keratitis have a significantly poorer ocular surface condition compared with that of normal controls.

Recurrent uncomplicated cystitis in women: allowing patients to self-initiate antibiotic therapy.

PubMed

2014-02-01

Acute uncomplicated cystitis is a lower urinary tract infection occurring in the absence of anatomic or functional abnormalities of the urinary tract or any other complicating factors.The organism responsible is often an enterobacterium, especially Escherichia coli. What is the role of antibiotic therapy for non-pregnant women with recurrent acute uncomplicated cystitis? We reviewed the available evidence using the standard Prescrire methodology. A single oral dose of fosfomycin trometamol is the antibiotic of choice for treating an episode of acute uncomplicated cystitis. Alternative antibiotics are certain fluoroquinolones or co-trimoxazole (a fixed-dose combination of sulfamethoxazole and trimethoprim). For recurrent acute uncomplicated cystitis, cranberry juice has modest efficacy in reducing the frequency of episodes. A number of non-drug measures are typically proposed, although their effects are unproven: drinking sufficient fluids and urinating regularly; urinating after sexual intercourse; and avoiding spermicides. The strategy that results in the lowest antibiotic exposure is a short course of antibiotics for each episode of urinary tract infection, initiated as soon as clinical symptoms appear. Long-term antibiotic therapy is sometimes offered. According to one systematic review, women taking long-term prophylactic antibiotic therapy had about 6 times fewer clinical recurrences than with placebo. According to one randomised trial, 3 g of fosfomycin trometamol taken as a single dose every ten days reduced the frequency of recurrence, resulting in 0.14 episodes of infection per year on average versus about 3 episodes with placebo (p < 0.001). The amount of antibiotic used when fosfomycin trometamol is taken every 10 days for 6 months is equivalent to treatment of 18 acute episodes of cystitis. When cystitis appears to be associated with sexual intercourse, two small randomised trials suggest that routine postcoital antibiotic treatment is more effective

Over 70% of the general population worldwide is positive for antibodies against polyomavirus hominis type 1 (BKV). Polyomavirus can be reactivated in immunocompromised patients and thereby induce urogenital tract infection, including cystitis. To describe the computed tomography (CT) findings of human polyomavirus-induced cystitis in adult patients after allogeneic hematopoietic stem cell transplantation (allogeneic HCT). The study population was a retrospective cohort of 11 consecutive adult patients (eight men, three women; age range 22-59 years, mean 42.9 years) who received allogeneic HCT between December 2003 and December 2007 and were tested positive for urinary BKV infection. All CT scans were evaluated with regard to bladder wall thickness, mucosal enhancement, distinct layering of thickened bladder wall, and presence of intravesical clots, perivesical stranding as well as attenuation values of intravesical urine. Clinical data concerning transplant and conditioning regimen variables and laboratory parameters were correlated with degree and extent of imaging findings. All patients had clinical signs of cystitis with different degrees of thickening of the urinary bladder wall. Well-delineated urinary bladder layers were present in six patients. Thickening of the urinary bladder wall was continuous in nine of 11 patients. Increased attenuation of intravesical urine was found in seven patients with hemorrhagic cystitis. Four patients had intraluminal clots. Perivesical stranding was not a major CT finding, occurring in a mild fashion in three of 11 patients. The clinical classification of hemorrhagic cystitis did not correlate with the analyzed imaging parameters. Patient outcome was not influenced by this infectious complication. CT findings in patients with polyomavirus BK cystitis consist of different degrees of bladder wall thickening usually with good delineation of all mural layers and increased mucosal enhancement. These findings are not specific for

Xanthogranulomatous cystitis is a rare, benign, chronic inflammatory disease of the bladder, mimicking malignancy with unknown etiology. Herein, we report a 57-year-old man who presented with pollakiuria, nocturia, dysuria, left flank pain, and a palpable mass on the right lower abdomen. Computerized tomography demonstrated an obstructing 10-mm stone in the lower third of the left ureter and a 6-cm solid mass on the right at the anterolateral wall of the bladder. The mass presented local perivesical invasion at the anterolateral side. Cystouretroscopy revealed a mass protruding into the bladder cavity with edematous smooth surface. Frozen section analysis of the partial cystectomy specimen could not rule out malignancy. Therefore, radical cystoprostatectomy and ureterolithotomy were performed. Histologically, fibrosis, numerous plasma cells, eosinophils, and, immunohistochemically, CD68-positive epithelioid and foamy macrophages were detected. Localized prostatic adenocarcinoma was also found. The present case of xanthogranulomatous cystitis is the 23rd to be reported in the world literature.

ABSTRACT Purpose To examine the safety and efficacy of hyperbaric oxygen as the primary and sole treatment for severe radiation-induced haemorrhagic cystitis. Materials and methods Hyperbaric oxygen was prospectively applied as primary treatment in 38 patients with severe radiation cystitis. Our primary endpoint was the incidence of complete and partial response to treatment, while the secondary endpoints included the duration of response, the correlation of treatment success-rate to the interval between the onset of haematuria and initiation of therapy, blood transfusion need and total radiation dose, the number of sessions to success, the avoidance of surgery and the overall survival. Results All patients completed therapy without complications with a mean follow-up of 29.33 months. Median number of sessions needed was 33. Complete and partial response rate was 86.8% and 13.2%, respectively. All 33 patients with complete response received therapy within 6 months of the haematuria onset. One patient needed cystectomy, while 33 patients were alive at the end of follow-up. Conclusions Our study suggests the early primary use of hyperbaric oxygen for radiation-induced severe cystitis as an effective and safe treatment option. PMID:28338304

Intracavitary irradiation is effective in the treatment of noninvasive papillary transitional cell carcinoma and carcinoma in situ of the bladder. Mortality has not been associated with this form of therapy. The morbidity associated with intracavitary irradiation consists of mild to severe radiation cystitis and we report 2 such cases. One patient is from a series of 65 patients with noninvasive bladder tumors treated with intracavitary irradiation at this clinic since 1965. The second patient had noninvasive bladder tumors and was treated with intracavitary irradiation elsewhere. In both patients severe radiation cystitis subsequently developed, requiring simple cystectomy and urinary diversion. Themore » potential for this serious side effect must be considered when choosing a form of therapy for patients with noninvasive papillary transitional cell carcinoma and carcinoma in situ of the bladder.« less

Interstitial nephritis.

There are many causes of interstitial nephritis other than pyelonephritis. The term interstitial nephritis does not connote a single etiologic or pathogenetic mechanism; it rather arbitrarily places together a wider variety of renal diseases that have a predilection for early and major involvement of the renal interstitium. The prototype of acute interstitial nephritis is acute pyelonephritis. In addition, there is a drug-related acute interstitial disease that is probably of immunological nature and usually reverses with discontinuance of the offending drug. Chronic interstitial nephritis includes many diverse illnesses. Nonobstructive pyelonephritis occurs but its prevalence is debated. Analgesic abuse nephropathy is not rare and is potentially reversible. Papillary necrosis has many causes and a wide spectrum of clinical presentations. Heavy metals, such as lead, cause interstitial nephritis. Balkan nephropathy occurs in an endemic area and although not bacterial in origin is of unknown cause.

Effect of tramadol on pain-related behaviors and bladder overactivity in rodent cystitis models.

PubMed

Oyama, Tatsuya; Homan, Takashi; Kyotani, Junko; Oka, Michiko

2012-02-15

Tramadol is a widely used analgesic that stimulates the μ opioid receptor and inhibits serotonin and noradrenalin reuptake. There have been studies on the analgesic effects of tramadol based on the tail-flick test, the formalin test, and the induction of allodynia by sciatic-nerve ligation. However, the effects of tramadol on behaviors related to bladder pain and bladder overactivity induced by cystitis have not been reported. To investigate the usefulness of tramadol for patients with cystitis, we investigated these effects of tramadol in rodent cystitis models. Intraperitoneal injection of cyclophosphamide caused bladder-specific inflammation and increases in pain-related behaviors, the number of voids and bladder weight in mice. Tramadol suppressed the cyclophosphamide-induced pain-related behaviors but did not affect the number of voids or the bladder weight. During continuous-infusion cystometrograms in anesthetized rats, cyclophosphamide shortened the intercontraction interval, indicating bladder overactivity. Tramadol significantly prolonged the intercontraction interval, and the effect was partially blocked by the opioid antagonist naloxone. This finding indicates that μ opioid receptors may be involved in the action of tramadol. In conclusion, tramadol ameliorated cyclophosphamide-induced bladder-pain-related behaviors and bladder overactivity in rodents. These findings suggest that tramadol might be a treatment option for cystitis-induced bladder pain and bladder overactivity. Copyright © 2011 Elsevier B.V. All rights reserved.

Hemorrhagic cystitis is a common complication in hematopoietic stem cell transplant recipients. We report here a case of severe BKV-associated hemorrhagic cystitis who did not respond to intravenous cidofovir. Overt hematuria successfully resolved after a few days on hyperbaric oxygen and intravesical instillations of cidofovir, while BK viruria dropped after a few weeks and remained low. We review the literature for therapeutic options in hemorrhagic cystitis and try to explain how hyperbaric oxygen stimulates mucosal repair in the urinary bladder.

Diffusion and interactions of interstitials in hard-sphere interstitial solid solutions

van der Meer, Berend; Lathouwers, Emma; Smallenburg, Frank; Filion, Laura

2017-12-01

Using computer simulations, we study the dynamics and interactions of interstitial particles in hard-sphere interstitial solid solutions. We calculate the free-energy barriers associated with their diffusion for a range of size ratios and densities. By applying classical transition state theory to these free-energy barriers, we predict the diffusion coefficients, which we find to be in good agreement with diffusion coefficients as measured using event-driven molecular dynamics simulations. These results highlight that transition state theory can capture the interstitial dynamics in the hard-sphere model system. Additionally, we quantify the interactions between the interstitials. We find that, apart from excluded volume interactions, the interstitial-interstitial interactions are almost ideal in our system. Lastly, we show that the interstitial diffusivity can be inferred from the large-particle fluctuations alone, thus providing an empirical relationship between the large-particle fluctuations and the interstitial diffusivity.

Intravesical instillation of hyaluronic acid (HA) plus chondroitin sulfate (CS) in women with bladder pain syndrome/interstitial cystitis (BPS/IC) has shown promising results. This study compared the efficacy, safety, and costs of intravesical HA/CS (Ialuril ® , IBSA) to dimethyl sulfoxide (DMSO). Randomized, open-label, multicenter study involving 110 women with BPS/IC. The allocation ratio (HA/CS:DMSO) was 2:1. Thirteen weekly instillations of HA (1.6%)/CS (2.0%) or 50% DMSO were given. Patients were evaluated at 3 (end-of-treatment) and 6 months. Primary endpoint was reduction in pain intensity at 6 months by visual analogue scale (VAS) versus baseline. Secondary efficacy measurements were quality of life and economic analyses. A significant reduction in pain intensity was observed at 6 months in both treatment groups versus baseline (P < 0.0001) in the intention-to-treat population. Treatment with HA/CS resulted in a greater reduction in pain intensity at 6 months compared with DMSO for the per-protocol population (mean VAS reduction 44.77 ± 25.07 vs. 28.89 ± 31.14, respectively; P = 0.0186). There were no significant differences between treatment groups in secondary outcomes. At least one adverse event was reported in 14.86% and 30.56% of patients in the HA/CS and DMSO groups, respectively. There were significantly fewer treatment-related adverse events for HA/CS versus DMSO (1.35% vs. 22.22%; P = 0.001). Considering direct healthcare costs, the incremental cost-effectiveness ratio of HA/CS versus DMSO fell between 3735€/quality-adjusted life years (QALY) and 8003€/QALY. Treatment with HA/CS appears to be as effective as DMSO with a potentially more favorable safety profile. Both treatments increased health-related quality of life, while HA/CS showed a more acceptable cost-effectiveness profile. © 2016 Wiley Periodicals, Inc.

Background/Aim: Breast cancer survivors in adjuvant therapy, frequently experience the estrogen deficiency with genitourinary symptoms mostly represented by recurrent bacterial cystitis. The objective of the present study was to evaluate the effectiveness of N-acetylcysteine, D-mannose and Morinda citrifolia fruit extract (NDM), when associated to antibiotic therapy, in reducing the persistence of recurrent cystitis in this risk population. Patients and Methods: Sixty breast cancer survived women with recurrent cystitis were retrospectively examined. Group 1, comprised of 40 patients treated with antibiotic therapy associated with NDM lasting for six months, Group 2 comprised of 20 patients treated with antibiotics alone. Results: The use of NDM in combination with antibiotic therapy showed a significant reduction in positive urine cultures, compared to antibiotics alone. Subjects of Group 1 rather than those of Group 2, showed improvement in symptoms score of urgency, frequency, urge incontinence, recurrent cystitis, bladder and urethral pain.

Breast cancer survivors in adjuvant therapy, frequently experience the estrogen deficiency with genitourinary symptoms mostly represented by recurrent bacterial cystitis. The objective of the present study was to evaluate the effectiveness of N-acetylcysteine, D-mannose and Morinda citrifolia fruit extract (NDM), when associated to antibiotic therapy, in reducing the persistence of recurrent cystitis in this risk population. Sixty breast cancer survived women with recurrent cystitis were retrospectively examined. Group 1, comprised of 40 patients treated with antibiotic therapy associated with NDM lasting for six months, Group 2 comprised of 20 patients treated with antibiotics alone. The use of NDM in combination with antibiotic therapy showed a significant reduction in positive urine cultures, compared to antibiotics alone. Subjects of Group 1 rather than those of Group 2, showed improvement in symptoms score of urgency, frequency, urge incontinence, recurrent cystitis, bladder and urethral pain. In breast cancer survived women affected by genitourinary discomfort, the combination of NDM and antibiotic therapy showed a greater efficacy in reducing urinary tract infections and urinary discomfort with respect to antibiotic use only.

Background Hemorrhagic cystitis is a common cause of morbidity after allogeneic stem cell transplantation, frequently associated with BK virus infection. We hypothesized that patients with positive BK viruria before unrelated or mismatched related donor allogeneic hematopoietic stem cell transplantation have a higher incidence of hemorrhagic cystitis. Design and Methods To test this hypothesis, we prospectively studied 209 patients (median age 49 years, range 19–71) with hematologic malignancies who received bone marrow (n=78), peripheral blood (n=108) or umbilical cord blood (n=23) allogeneic hematopoietic stem cell transplantation after myeloablative (n=110) or reduced intensity conditioning (n=99). Donors were unrelated (n=201) or haploidentical related (n=8). Results Twenty-five patients developed hemorrhagic cystitis. Pre-transplant BK viruria detected by quantitative PCR was positive in 96 patients. The one-year cumulative incidence of hemorrhagic cystitis was 16% in the PCR-positive group versus 9% in the PCR-negative group (P=0.1). The use of umbilical cord blood or a haploidentical donor was the only significant predictor of the incidence of hemorrhagic cystitis on univariate analysis. There was also a trend for a higher incidence after myeloablative conditioning. Multivariate analysis showed that patients who had a positive PCR pre-transplant and received haploidentical or cord blood grafts with myeloablative conditioning had a significantly higher risk of developing hemorrhagic cystitis (58%) than all other recipients (7%, P<0.001). Conclusions Hemorrhagic cystitis is the result of a complex interaction of donor type, preparative regimen intensity, and BK viruria. PMID:20410183

We have assessed the efficacy and safety of Escherichia coli extract (ECE; Uro-Vaxom®) which contains active immunostimulating fractions, in the prophylactic treatment of chronically recurrent cystitis. Forty-two patients with more than 2 episodes of cystitis in the proceeding 6 months were treated for 3 months with one capsule daily of ECE and observed for a further 6 months. The primary efficacy criterion was the number of episodes of recurrent cystitis during the 6 months after treatment compared to those during the 6 months before treatment. At the end of the 9-month trial, 34 patients (all women) were eligible for statistical analysis. Their mean age was 56.4 yr (range, 34-75 yr), and they had experienced recurrent urinary tract infections for 7.2±5.2 yr. The number of recurrences was significantly lower during the 6-month follow-up period than during the 6 months preceding the trial (0.35 vs. 4.26, P<0.001). During the follow-up, 28 (82.4%) patients had no recurrences and 4 (11.8%) had 1 each. In patients who relapsed, ECE alleviated cystitis symptoms, including painful voiding, frequency and urgency. There were no serious adverse events related to the study drug. Our study demonstrates the efficacy and safety of ECE in the prophylactic treatment of chronically recurrent cystitis. PMID:20191044

Anorectal and Pelvic Pain

Bharucha, Adil E.; Lee, Tae Hee

2016-01-01

Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the three most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first two conditions occur in both sexes, while the latter occurs only in men. They are defined by symptoms, supplemented with levator tenderness (levator ani syndrome) and bladder mucosal inflammation (interstitial cystitis). Although distinct, these conditions share several similarities, including associations with dysfunctional voiding or defecation, comorbid conditions (eg, fibromyalgia, depression), impaired quality of life, and increased health care utilization. Several factors, including pelvic floor muscle tension, peripheral inflammation, peripheral and central sensitization, and psychosocial factors, have been implicated in the pathogenesis. The management is tailored to symptoms, is partly supported by clinical trials, and includes multidisciplinary approaches such as lifestyle modifications and pharmacologic, behavioral, and physical therapy. Opioids should not be avoided, and surgery has a limited role, primarily in refractory interstitial cystitis. PMID:27712641

Antibiotic-resistant Escherichia coli in women with acute cystitis in Canada

McIsaac, Warren J; Moineddin, Rahim; Meaney, Christopher; Mazzulli, Tony

2013-01-01

BACKGROUND: Trimethoprim-sulfamethoxazole (TMP-SMX) has been a traditional first-line antibiotic treatment for acute cystitis; however, guidelines do not recommend TMP-SMX in regions where Escherichia coli resistance exceeds 20%. While resistance is increasing, there are no recent Canadian estimates from a primary care setting to guide prescribing decisions. METHODS: A total of 330 family physicians assessed 752 women with suspected acute cystitis between 2009 and 2011. Physicians documented clinical features and collected urine for cultures for 430 (57.2%) women. The proportion of resistant isolates of E coli and exact binomial 95% CIs were estimated nationally, and compared regionally and demographically. These estimates were compared with those from a 2002 national study. RESULTS: The proportion of TMP-SMX-resistant E coli was 16.0% nationally (95% CI 11.3% to 21.8%). This was not statistically higher than 2002 (10.9% [P=0.14]). TMP-SMX resistance was increased in women ≤50 years of age (21.4%) compared with older women (10.7% [P=0.037]). In women with no antibiotic exposure in the previous three months, TMP-SMX-resistant E coli remained more prevalent in younger women (21.8%) compared with older women (4.4% [P=0.003]). The proportion of ciprofloxacin-resistant E coli was 5.5% nationally (95% CI 2.7% to 9.9%), and was increased compared with 2002 (1.1% [P=0.036]). Ciprofloxacin resistance was highest in British Columbia (17.7%) compared with other regions (2.7% [P=0.003]), and was increased compared with 2002 levels in this province (0.0% [P=0.025]). Nitrofurantoin-resistant E coli levels were low (0.5% [95% CI 0.01% to 2.7%). DISCUSSION: The proportion of TMP-SMX-resistant E coli causing acute cystitis in women in Canada remains below 20% nationally, but may exceed this level in premenopausal women. Ciprofloxacin resistance has increased, notably in British Columbia. Nitrofurantoin resistance levels are low across the country. These observations indicate that

Objective The aim of this study was to evaluate the usefulness of ultrasonography in the diagnosis of hemorrhagic cystitis following bone marrow transplantation in children. Material and methods The study involved an analysis of clinical material and the results of imaging tests performed in 334 patients who underwent hematopoietic cell transplantation. Ultrasonographic findings in 42 patients with hemorrhagic cystitis were analyzed in detail. The ultrasound images served to assess the severity of hemorrhagic cystitis and the results were compared with the clinical assessment of the disease on the Droller scale, as well as the laboratory and endoscopic tests. Results In the studied group of patients hemorrhagic cystitis following allogeneic transplantation was diagnosed in 12.5% cases. 73.8% patients received transplants from unrelated donors, 26.2% – from compatible siblings. The study revealed a higher incidence of hemorrhagic cystitis in children above 10 years of age. Grade 3 according to the Droller was diagnosed in 42.9%, grade 2 – in 30.9%, grade 4 – in 14.3%, and grade 1 – in 11.9% patients. The number of ultrasound examinations depended on the clinical symptoms, severity, duration and co-occurrence of other complications following the transplantation and was within the 1–15 range (average: 4.6). Grades 3 and 4 were related to the poor clinical condition of the patients and to their longer hospitalization. During this period there was an increased risk of renal malfunction and acute renal failure, post-inflammatory narrowing of the ureters, hydronephrosis, and in grade 4 the fibrosis of the bladder with reduced bladder capacity. Analyses demonstrated a significant correlation between the ultrasound image of the bladder wall and the clinical severity. Conclusions Ultrasound with Doppler options remains the primary diagnostic tool in the evaluation of hemorrhagic cystitis, and is useful in terms of its diagnosis, determination of the severity, and

Cryptosporidium infection was associated with colitis and cystitis in 2 green iguanas (Iguana iguana). The disease was characterized by a chronic clinical course of cloacal prolapses and cystitis. Histological examination of the gut and urinary bladder showed numerous Cryptosporidium developmental stages on the surface of the epithelium with mixed inflammatory response in the lamina propria. Cryptosporidium oocysts were visualised in a cytological preparation of the faeces. Based on the small subunit ribosomal RNA gene the cryptosporidia were characterized as belonging to the intestinal cryptosporidial lineage, but not to Cryptosporidium saurophilum or Cryptosporidium serpentis species.

A Novel Approach for the Treatment of Radiation-Induced Hemorrhagic Cystitis with the GreenLight™ XPS Laser

PubMed Central

Martinez, Daniel Roberto; Ercole, Cesar E; Lopez, Juan Gabriel; Parker, Justin; Hall, Mary K

2015-01-01

ABSTRACT Introduction: The treatment of pelvic malignancies with radiotherapy can develop severe sequelae, especially radiation-induced hemorrhagic cystitis. It is a progressive disease that can lead to the need for blood transfusion, hospitalizations, and surgical interventions. This tends to affect the quality of life of these patients, and management can at times be difficult. We have evaluated the GreenLight Xcelerated Performance System (XPS) with TruCoag, although primarily used for management of benign prostatic hypertrophy (BPH), for the treatment of radiation-induced hemorrhagic cystitis. Materials and Methods: After International Review Board (IRB) approval, a retrospective chart review was performed in addition to a literature search. A series of four male patients, mean age of 81 years, with radiation-induced hemorrhagic cystitis secondary to radiotherapy for pelvic malignancies (3 prostate cancer, 1 rectal cancer) were successfully treated with the GreenLight laser after unsuccessful treatment with current therapies described in the literature. Results: All four patients treated with the GreenLight laser had resolution of their hematuria after one treatment and were discharge from the hospital with clear urine. Conclusion: The GreenLight XPS laser shows promising results for the treatment of patients with radiation-induced hemorrhagic cystitis, and deserves further evaluation and validation, especially since there is limited data available in the literature regarding the use of this technology for the treatment of this devastating condition.

To evaluate urinary bladder wall thickness (BWT) assessed by ultrasound as a diagnostic tool for cystitis cystica. This was a 9-year prospective study comprising 120 prepubertal girls. Sixty subjects of whom half underwent cystoscopy represented cases while the other 60 (those with a single urinary tract infection and healthy subjects) represented controls. Based on receiver operating characteristics (ROC) analysis, BWT discriminated very well between cases and controls with area under the ROC curve close to 1.0. At the optimum cut-off defined at 3.9 mm, negative predictive value (NPV) was 100% leaving no probability of cystic cystitis with BWT <3.9 mm. Positive predictive value (PPV) was also very high (95.2%), indicating only around 4.82% probability of no cystic cystitis in patients with BWT values ≥3.9 mm. BWT could also distinguish between healthy subjects and those with a cured single urinary tract infection, although discriminatory properties were moderate (area under ROC 86.7%, PPV 78.8%, NPV 85.2%). Ultrasound mucosal bladder wall measurement is a non-invasive, simple and quite reliable method in diagnosis of cystitis cystica in prepubertal girls with recurrent urinary tract infections.

This study utilized magnetic resonance imaging (MRI) to monitor the real-time status of the urinary bladder in normal and diseased states following cyclophosphamide (CYP)-induced cystitis, and also examined the role of the phosphoinositide 3-kinase (PI3K) pathway in the regulation of urinary bladder hypertrophy in vivo. Our results showed that under MRI visualization the urinary bladder wall was significantly thickened at 8 h and 48 h post CYP injection. The intravesical volume of the urinary bladder was also markedly reduced. Treatment of the cystitis animals with a specific PI3K inhibitor LY294002 reduced cystitis-induced bladder wall thickening and enlarged the intravesical volumes. To confirm the MRI results, we performed H&E stain postmortem and examined the levels of type I collagen by real-time PCR and western blot. Inhibition of the PI3K in vivo reduced the levels of type I collagen mRNA and protein in the urinary bladder ultimately attenuating cystitis-induced bladder hypertrophy. The bladder mass calculated according to MRI data was consistent to the bladder weight measured ex vivo under each drug treatment. MRI results also showed that the urinary bladder from animals with cystitis demonstrated high magnetic signal intensity indicating considerable inflammation of the urinary bladder when compared to normal animals. This was confirmed by examination of the pro-inflammatory factors showing that interleukin (IL)-1α, IL-6 and tumor necrosis factor (TNF)α levels in the urinary bladder were increased with cystitis. Our results suggest that MRI can be a useful technique in tracing bladder anatomy and examining bladder hypertrophy in vivo during disease development and the PI3K pathway has a critical role in regulating bladder hypertrophy during cystitis.

Mycoplasma species relevant to the urogenital tract include mycoplasma hominis, mycoplasma genitalia and ureaplasma urealyticum. Their occurrence in the context of urogynaecological disease has been demonstrated in urethritis, cystitis and upper renal tract infections. Their role in hyperactive bladder and interstitial cystitis/painful bladder syndrome is controversial. All the above-mentioned microorganisms can occur as commensals or as potential pathogens. In most cases their role in any particular pathology cannot be proven, only presumed. The aim of this systematic review was to summarise current knowledge on the influence of mycoplasma and ureaplasma in urogynaecological pathology and to provide clinical guidance on diagnosis (when and how is pathogen detection indicated?) and treatment. 377 relevant articles were analysed. In summary: a urethral swab for PCR analysis of the three bacteria should be performed in the context of symptomatic sterile leukocyturia, chronic urethritis and suspected hyperactive bladder or interstitial cystitis/painful bladder syndrome. Symptomatic women should be treated strictly according to results of the antibiogram. PMID:29269957

Numerous proinflammatory cytokines have been implicated in the reorganization of lower urinary tract function following cyclophosphamide (CYP)-induced cystitis. The present study investigated the functional profile of three pleiotropic transforming growth factor-β (TGF-β) isoforms and receptor (TβR) variants in the normal and inflamed (CYP-induced cystitis) rat urinary bladder. Our findings indicate that TGF-β (1, 2, and 3) and TβR (1, 2, and 3) transcript and protein expression were regulated to varying degrees in the urothelium or detrusor smooth muscle following intermediate (48 h; 150 mg/kg ip) or chronic (75 mg/kg ip; once every 3 days for 10 days), but not acute (4 h; 150 mg/kg ip), CYP-induced cystitis. Conscious, open-outlet cystometry was performed to determine whether aberrant TGF-β signaling contributes to urinary bladder dysfunction following intermediate (48 h) CYP-induced cystitis. TβR-1 inhibition with SB505124 (5 μM) significantly (p ≤ 0.001) decreased voiding frequency and increased bladder capacity (2.5-fold), void volume (2.6-fold), and intercontraction intervals (2.5-fold) in CYP-treated (48 h) rats. Taken together, these results provide evidence for 1) the involvement of TGF-β in lower urinary tract neuroplasticity following urinary bladder inflammation, 2) a functional role of TGF-β signaling in the afferent limb of the micturition reflex, and 3) urinary bladder TβR-1 as a viable target to reduce voiding frequency with cystitis.

Objective To describe our technique utilising photoselective vaporisation of the bladder (PVB) for the management of haemorrhagic cystitis and initial results of 12 patients. Materials and Method An audit of theatre records of a single surgeon was performed to identify patients who had undergone PVB for management of radiation-cystitis. Rigid cystoscopy was performed. Ureteric catheters were placed and active bleeding sites targeted to optimise vision. Ablation was commenced using the vaporize function. When lasering around delicate structures the coagulation function was used. Ureteric catheters remained in situ for 24h. An 18Fr Foley catheter was placed. When urine output was clear continuous bladder irrigation was ceased. Both uretetric catheters and Foley catheter were removed prior to the 24hour mark. Results 12 patients were identified. 8 had previously required blood transfusion secondary to bladder haemorrhage. 9 were successfully treated and 2 saw improvement in haematuria but required a repeat procedure at 3 weeks post operatively. 4 went on to receive hyperbaric oxygenation as consolidative therapy. 1 patient was unsuccessfully treated and went on to cystectomy. There were no mortalities. No patients sustained bladder perforation or damage to surrounding structures. Conclusion Radiation cystitis can be life threatening and remains a challenge for the urologist with traditional intra-vescical treatments such as aluminium or formalin having variable results. We present an alternate technique using PVB to ablate the bladder mucosa, with good results. Consolidation with hyperbaric oxygen therapy may be considered. Our study is limited by small sample size and the presence of bilateral ureteric catheters leaving the bladder free from urine may impact immediate post operative outcomes. These initial results are promising however further prospective evaluation with a larger cohort and pre and post operative cystograms would enable better evaluation of this

Emphysematous cystitis is a rare clinically entity, more commonly seen in diabetic, immunocompromised patients, which was characterized by air within the bladder wall and lumen. A 83-year-old woman was introduced to our department with fever elevation and abnormal findings of computed tomography (CT). She took orally prednisolone for autoimmune hepatitis. Pelvic CT revealed diffuse air throughout the bladder wall. Urinalysis showed combined hematuria and pyuria. Escherichia coli was detected in blood culture. Abnormal findings of complete blood count and laboratory examination included an elevated WBC count (12,200/μL), C-reactive protein (11.7 mg/dL), and creatinine (1.07 mg/dL). Cystoscopy confirmed diffuse submucosal emphysema throughout. On the basis of diagnosis with emphysematous cystitis, she was treated with antibiotics based on the results of blood culture and indwelling Foley catheter. After treatment, the improvement of inflammatory findings and submucosal emphysema on cystoscopy and CT were achieved.

Cystitis is a common infection. The alarmingly high resistance rates exhibited by contemporary uropathogens necessitate the re-evaluation of old antibiotics. To evaluate the effectiveness and safety of fosfomycin compared with other antibiotics for the treatment of patients with cystitis. We performed a meta-analysis of randomized controlled trials (RCTs), generated from searches performed in PubMed, Scopus and Cochrane CENTRAL, which involved patients with cystitis treated with fosfomycin versus other antibiotics. Twenty-seven trials (eight double-blind) were included. Sixteen of these 27 trials involved exclusively non-pregnant female patients, 3 involved adult mixed populations of older age, 5 involved pregnant patients and 3 involved paediatric patients. Regarding clinical success, no difference was found in the comprehensive analysis regarding all comparators combined [10 RCTs, 1657 patients, risk ratio (RR) = 1.00, 95% confidence interval (CI) = 0.98-1.03] in trials involving non-pregnant females and in trials involving mixed populations. Insufficient relevant data were provided from trials involving paediatric and pregnant patients. No difference between fosfomycin and comparators was also found in all comparisons regarding the remaining effectiveness outcomes (namely microbiological success/relapse/re-infection). Fosfomycin had a comparable safety profile with the evaluated comparators in non-pregnant women, mixed and paediatric populations, whereas it was associated with significantly fewer adverse events in pregnant women (4 RCTs, 507 patients, RR = 0.35, 95% CI = 0.12-0.97). In the era of high drug resistance rates, reported even among community-acquired uropathogens, fosfomycin may provide a valuable alternative option for the treatment of cystitis in non-pregnant and pregnant women and in elderly and paediatric patients.

Synthetic feline facial pheromone (FFP) (Feliway; Ceva Animal Health) was assessed for the management of cats with recurrent feline idiopathic cystitis (FIC). Nine of 12 cats completed the randomised, double-blinded, placebo-controlled, crossover pilot study. They had their environment treated daily with either FFP or placebo for 2 months, after which time the treatment groups were reversed. Owners used visual analogue scales to define the severity of their cat's clinical signs and behavioural changes. Five (56%) of the owners stated that their cat's overall health was better when they were using FFP. Four (44%) of the owners noticed no difference between when using the FFP and when using the placebo. While there were no statistical differences between the two treatment groups there was a trend for the cats exposed to FFP to show fewer days with clinical signs of cystitis (FFP total, mean per cat+/-standard deviation, 30, 4.3+/-6.7; placebo 69, 9.9+/-19.1), a lower overall clinical score (1667, 238+/-476; 2009, 287+/-425), a reduced number of episodes of cystitis (9, 1.3+/-2.0; 10, 1.4+/-2.1) and reduced negative behavioural traits (e.g., less aggression and fear) (-128, -18.3+/-65.8; -73, -10.4+/-35.1).

Hodgkin's lymphoma is a disease with a high rate of curability under classic chemo-radiotherapy regimes. Complications due to chemotherapy could include viral reactivation due to chronic lymphopenia. BK virus (BKV) is a polyoma virus belonging to the Papovaviridae family with antibody seroprevalences in healthy populations varying from 60% to 80%. Initial infections are asymptomatic usually occur in early childhood, after which the viruses remain latent in the kidneys or urothelium. Reactivation of BKV occurs in individuals with severe immunosuppression during HIV infections, transplantation or, exceptionally, after classical chemotherapy. BKV incidence is approximately 0% to 5% in immunocompetent individuals. Reactivation is associated with nephropathy and haemorrhagic cystitis. Herein, we present a case of a haemorrhagic cystitis due to BKV reactivation in a patient with Hodgkin's disease treated with chemotherapy. PMID:22937308

We have determined if cyclophosphamide (CYP)-induced cystitis produces additional changes in growth factor/receptors expression in the urinary bladder (urothelium, detrusor) and lumbosacral (L6-S1) dorsal root ganglia (DRG) in a transgenic mouse model with chronic urothelial overexpression of NGF (NGF-OE). Functionally, NGF-OE mice treated with CYP exhibit significant increases in voiding frequency above that observed in control NGF-OE mice (no CYP). Quantitative PCR was used to determine NGF, BDNF, VEGF, and receptors (TrkA, TrkB, p75(NTR)) transcripts expression in tissues from NGF-OE and wild-type (WT) mice with CYP-induced cystitis of varying duration (4 h, 48 h, 8 days). In urothelium of control NGF-OE mice, NGF mRNA was significantly (p ≤ 0.001) increased. Urothelial expression of NGF mRNA in NGF-OE mice treated with CYP (4 h, 48 h, 8 days) was not further increased but maintained with all durations of CYP treatment evaluated. In contrast, CYP-induced cystitis (4 h, 48 h, 8 days) in NGF-OE mice demonstrated significant (p ≤ 0.05) regulation in BDNF, VEGF, TrkA, TrkB, and P75(NTR) mRNA in urothelium and detrusor smooth muscle. Similarly, CYP-induced cystitis (4 h, 48 h, 8 days) in NGF-OE mice resulted in significant (p ≤ 0.05), differential changes in transcript expression for NGF, BDNF, and receptors (TrkA, TrkB, p75(NTR)) in S1 DRG that was dependent on the duration-of CYP-induced cystitis. In general, NGF, BDNF, TrkA, and TrkB protein content in the urinary bladder increased in WT and NGF-OE mice with CYP-induced cystitis (4 h). Changes in NGF, TrkA and TrkB expression in the urinary bladder were significantly (p ≤ 0.05) greater in NGF-OE mice with CYP-induced cystitis (4 h) compared to WT mice with cystitis (4 h). However, the magnitude of change between WT and NGF-OE mice was only significantly (p ≤ 0.05) different for TrkB expression in urinary bladder of NGF-OE mice treated with CYP. These studies are

Summary Uropathogenic Escherichia coli (UPEC) contain multiple horizontally acquired pathogenicity-associated islands (PAI) implicated in the pathogenesis of urinary tract infection. In a murine model of cystitis, type 1 pili-mediated bladder epithelial invasion and intracellular proliferation are key events associated with UPEC virulence. In this study, we examined the mechanisms by which a conserved PAI contributes to UPEC pathogenesis in acute cystitis. In the human UPEC strain UTI89, spontaneous excision of PAI IIUTI89 disrupts the adjacent leuX tRNA locus. Loss of wild-type leuX-encoded tRNA5Leu significantly delayed, but did not eliminate, FimB recombinase-mediated phase variation of type 1 pili. FimX, an additional FimB-like, leuX-independent recombinase, was also found to mediate type 1 pili phase variation. However, whereas FimX activity is relatively slow in vitro, it is rapid in vivo as a non-piliated strain lacking the other fim recombinases rapidly expressed type 1 pili upon experimental infection. Finally, we found that disruption of leuX, but not loss of PAI IIUTI89 genes, reduced bladder epithelial invasion and intracellular proliferation, independent of type 1 piliation. These findings indicate that the predominant mechanism for preservation of PAI IIUTI89 during the establishment of acute cystitis is maintenance of wild-type leuX, and not PAI IIUTI89 gene content.

Intravesical instillation of glycosaminoglycans is a promising option for the treatment of chronic cystitis, as it supports the regeneration of the damaged urothelial layer. We investigated the efficacy of short-term intravesical chondroitin sulphate treatment (six courses of instillation) in patients with chronic radiotherapy- or chemotherapy-associated cystitis. This prospective, observational study included patients with chronic radiotherapy- or chemotherapy-associated cystitis, who received six once-weekly intravesical instillations of 0.2% chondroitin sulphate 40 mL. Every week, patients recorded their symptoms and their benefits and tolerance of treatment, using a self-completed questionnaire. The study included 16 patients (mean age 68.5 years; 50% male). During the study, a reduction in all evaluated parameters was observed. After one dose of chondroitin sulphate, symptom improvement was observed in 38% of patients, and after the second dose, an additional 31% of patients showed improvement. At week 6, 80% of patients had either improved or were symptom free, and significant improvements in urinary urgency (p = 0.0082), pollakisuria (p = 0.0022), urge frequency (p = 0.0033) and lower abdominal pain (p = 0.0449) were observed. Haematuria, present in 9 of the 16 patients at baseline, was completely resolved in all cases after 6 weeks. The majority of patients (93%) evaluated the tolerance of chondroitin sulphate as 'good' or 'very good'. No treatment-related adverse events were reported. Intravesical administration of chondroitin sulphate was effective for the treatment of radiotherapy- or chemotherapy-associated cystitis. Even short-term treatment appears to be effective in reducing symptoms and improving the quality of life of patients.

Smoking-related interstitial lung diseases.

In pulmonary pathology, a wide spectrum of morphological changes is related to the consequences of smoking, and recognizing them on surgical specimens and on small transbronchial biopsies represents a challenge for the pathologist. Respiratory bronchiolitis, also referred to as smoker's bronchiolitis, is a common histologic feature found in the lung tissue of cigarette smokers. When identified as the sole histopathologic finding in the clinical setting of symptomatic interstitial lung disease, a diagnosis of respiratory bronchiolitis-interstitial lung disease is made. Since smoking is recognized to cause a variety of histologic patterns encompassing respiratory bronchiolitis, respiratory bronchiolitis-interstitial lung disease, desquamative interstitial pneumonia and pulmonary Langerhans cell hystiocytosis, smoking-related interstitial lung disease may be a useful concept to keep in mind for the pathologists. The relationship of smoking with each of these entities has been largely established on the basis of epidemiologic evidence. Although they have been retained as distinct and separate conditions in various classifications of interstitial lung diseases, these entities share a number of clinical, radiologic, and pathologic features suggesting that they represent a spectrum of patterns of interstitial lung disease occurring in predisposed individuals who smoke. Evaluation of histologic features, particularly in surgical lung biopsy samples, is important in making the distinction between these disorders. However, even after tissue biopsy, it may sometimes be difficult to clearly separate these entities. Recently, respiratory bronchiolitis-interstitial lung disease with fibrosis has been described and postulated that this is a smoking-related condition distinct from fibrotic non-specific interstitial pneumonia.

This chapter explains the procedure of ethanol-induced ulcer to check the protective effect of drugs over induced ulcer in rats. Ulcer is defined as the erosion in the lining of the stomach or duodenum and is caused by the disruptions of the gastric mucosal defence and repair systems. Ulceration of stomach is called gastric ulcer and that of duodenum is called duodenal ulcer and together peptic ulcer. In clinical practice, peptic ulcer is one of the most prevalent gastrointestinal disorders, which commonly occurs in developed countries.

OBJECTIVE To determine the prevalence of bacteriuria (ie, a positive microbial culture result for ≥ 1 urine sample) in dogs with chronic kidney disease (CKD) and characterize findings of subclinical bacteriuria (SBU), bacterial cystitis, or pyelonephritis in these patients. DESIGN Retrospective, observational study. ANIMALS 182 dogs. PROCEDURES Medical records from January 2010 through July 2015 were reviewed to identify dogs with CKD that underwent urinalysis and urine microbial culture. Signalment, clinicopathologic data, stage of CKD according to previously published guidelines, results of urinalysis and urine culture, and abdominal ultrasonographic findings were recorded. Dogs with positive urine culture results were categorized as having SBU, bacterial cystitis, or pyelonephritis on the basis of these data. Prevalence of bacteriuria was calculated. Associations between CKD stage, presence of bacteriuria, and diagnosis category were analyzed statistically. RESULTS 33 of 182 (18.1%) dogs (40/235 [17.0%] urine samples) had positive culture results. All dogs received antimicrobials on the basis of culture and susceptibility test findings. Most positive culture results (18/40 [45%] samples) were found for dogs with SBU, followed by dogs with pyelonephritis (16/40 [40%]) and cystitis (6/40 [15%]). Escherichia coli was the most frequently observed isolate (29/40 [73%] cultures from 25/33 dogs). The CKD stage was not associated with presence of bacteriuria or diagnosis category. CONCLUSIONS AND CLINICAL RELEVANCE The prevalence of positive urine culture results in dogs with CKD was lower than that reported for dogs with some systemic diseases that may predispose to infection. Prospective research is needed to assess the clinical importance of SBU in dogs with CKD.

Recently, abnormal cellular immune response has been considered responsible for the oral lesion in the recurrent aphthous ulceration (RAU). For reasons not yet defined, antigens of the oral microbiota would trigger abnormal Th1 immune response against epithelial cells. On the other hand, studies have demonstrated that heat shock proteins (HSP) can block the production of proinflammatory cytokine through inhibition of NF-kappaB and mitogen-activated protein kinase pathways or activate anti-inflammatory cytokines and therefore control the magnitude of the immune response. HSP27 has been considered a powerful inductor of IL-10, a major inhibitor of Th1 response. Using immunohistochemistry, we studied the expression and location of HSP27 and IL-10 in ulcerated lesions clinically diagnosed as RAU (n = 27) and to compare it with that of oral clinically normal mucosa (CT; n = 6) and of other inflammatory chronic diseases such as oral fibrous inflammatory hyperplasia (FIH; n = 18), Crohn's disease (CD; n = 10) and ulcerative colitis (UC; n = 9). A lower proportion of HSP27-positive epithelial cells in RAU and CD were observed when compared with CT and FIH (P < 0.001**; P = 0.013**). A lower proportion of IL-10-positive interstitial cells in RAU was observed when compared with FIH, UC, CT and CD (P < 0.001**; P < 0.001**; P < 0.001**; P = 0.034*). Altogether the data suggest that a reduced cellular expression of HSP27 and IL-10 in RAU might be related with the aetiopathogenesis of the ulcerated oral lesions.

To study the magnitude of radiation cystitis following radiation therapy for carcinoma cervix, and propose an algorithm to decide on early diversion, with or without vesicovaginostomy. Women who developed radiation cystitis following radiotherapy for carcinoma cervix from January 1998 to December 2011 were included in this retrospective study. Electronic hospital records were analysed to document the presence of radiation cystitis. All women who developed evidence of radiation-induced cystitis, according to the common toxicity and Radiation Therapy Oncology Group criteria, were included in the study. We looked at transfusion requirements, number of hospital admissions, quality of life and cost involved. Chi-square tests were done where applicable. SPSS version 16 was used for analysis. Of the 902 patients who received radiation for carcinoma cervix in the 13-year period, 62 (6.87%) developed grade 3/4 cystitis. Twenty-eight of them underwent ileal conduit diversion, with 18 undergoing concomitant vesicovaginostomy. When compared with the patients who did not have diversion, the transfusion requirements, number of hospital admissions and quality of life had a statistically significant difference. Cost analysis of early diversion too showed a marginal benefit with early diversion. The limitation of the study was that it was retrospective in nature. In radiation cystitis, multiple hospital admissions and consequential increase in cost is the norm. In severe disease, early diversion is a prudent, cost-effective approach with good quality of life and early return to normal activity. © 2014 Royal Australasian College of Surgeons.

Urinary tract infections (UTIs) are common in the female population and, over a lifetime, about half of women have at least one episode of UTI requiring antibiotic therapy. The aim of the current study was to compare two different strategies for preventing recurrent bacterial cystitis: intravesical instillation of hyaluronic acid (HA) plus chondroitin sulfate (CS), and antibiotic prophylaxis with sulfamethoxazole plus trimethoprim. This was a retrospective review of two different cohorts of women affected by recurrent bacterial cystitis. Cases (experimental group) were women who received intravesical instillations of a sterile solution of high concentration of HA + CS in 50 mL water with calcium chloride every week during the 1(st) month and then once monthly for 4 months. The control group included women who received traditional therapy for recurrent cystitis based on daily antibiotic prophylaxis using sulfamethoxazole 200 mg plus trimethoprim 40 mg for 6 weeks. Ninety-eight and 76 patients were treated with experimental and control treatments, respectively. At 12 months after treatment, 69 and 109 UTIs were detected in the experimental and control groups, respectively. The proportion of patients free from UTIs was significantly higher in the experimental than in the control group (36.7% vs. 21.0%; p = 0.03). Experimental treatment was well tolerated and none of the patients stopped it. The intravesical instillation of HA + CS is more effective than long-term antibiotic prophylaxis for preventing recurrent bacterial cystitis. Copyright © 2015. Published by Elsevier B.V.

What's known on the subject? and What does the study add? Interstitial cystitis (IC) is a prevalent and debilitating pelvic disorder generally accompanied by chronic pain combined with chronic urinating problems. Over one million Americans are affected, especially middle-aged women. However, its aetiology or mechanism remains unclear. No efficient drug has been provided to patients. Several urinary biomarker candidates have been identified for IC; among the most promising is antiproliferative factor (APF), whose biological activity is detectable in urine specimens from >94% of patients with both ulcerative and non-ulcerative IC. The present study identified several important mediators of the effect of APF on bladder cell physiology, suggesting several candidate drug targets against IC. In an attempt to identify potential proteins and genes regulated by APF in vivo, and to possibly expand the APF-regulated network identified by stable isotope labelling by amino acids in cell culture (SILAC), we performed an integration analysis of our own SILAC data and the microarray data of Gamper et al. (2009) BMC Genomics 10: 199. Notably, two of the proteins (i.e. MAPKSP1 and GSPT1) that are down-regulated by APF are involved in the activation of mTORC1, suggesting that the mammalian target of rapamycin (mTOR) pathway is potentially a critical pathway regulated by APF in vivo. Several components of the mTOR pathway are currently being studied as potential therapeutic targets in other diseases. Our analysis suggests that this pathway might also be relevant in the design of diagnostic tools and medications targeting IC. • To enhance our understanding of the interstitial cystitis urine biomarker antiproliferative factor (APF), as well as interstitial cystitis biology more generally at the systems level, we reanalyzed recently published large-scale quantitative proteomics and in vivo transcriptomics data sets using an integration analysis tool that we have developed. • To

The objective of this study was to determine if neonatal cystitis alters colonic sensitivity later in life and to investigate the role of peripheral mechanisms. Neonatal rats received intravesical zymosan, normal saline, or anesthesia only for three consecutive days [(postnatal (PN) days 14-16)]. The estrous cycle phase was determined prior to recording the visceromotor response (VMR) to colorectal distension (CRD) in adult rats. Eosinophils and mast cells were examined from colon and bladder tissues. CRD- or urinary bladder distension (UBD)-sensitive pelvic nerve afferents (PNAs) were identified and their responses to distension were examined. The relative expression of N-methyl-d-aspartic acid (NMDA)-NR1 subunit in the lumbo-sacral (L6-S1) spinal cord was examined using Western blot. The VMR to CRD (≥10mmHg) in the neonatal zymosan group was significantly higher than control in both the diestrus, estrus phase and in all phases combined. There was no difference in the total number of eosinophils, mast cells or number of degranulated mast cells between groups. The spontaneous firing of UBD, but not CRD-sensitive PNAs from the zymosan-treated rats was significantly higher than the saline-treated control. However, the mechanosensitive properties of PNAs to CRD or UBD were no different between groups (P>0.05). The expression of spinal NR1 subunit was significantly higher in zymosan-treated rats compared with saline-treated rats (P<0.05). Neonatal cystitis results in colonic hypersensitivity in adult rats without changing tissue histology or the mechanosensitive properties of CRD-sensitive PNAs. Neonatal cystitis does result in overexpression of spinal NR1 subunit in adult rats. © 2011 Blackwell Publishing Ltd.

Cyclophosphamide (CYP) induced hemorrhagic cystitis is a dose-limiting side effect involving increased oxidative stress, inflammatory cytokines and suppressed activity of nuclear factor related erythroid 2-related factor (Nrf2). Thymoquinone (TQ), an active constituent of Nigella sativa seeds, is reported to increase the expression of Nrf2, exert antioxidant action, and anti-inflammatory effects in the experimental animals. The present study was designed to explore the effects of TQ on CYP-induced hemorrhagic cystitis in Balb/c mice. Cystitis was induced by a single intraperitoneal injection of CYP (200 mg/kg). TQ was administered intraperitoneally at 5, 10 and 20 mg/kg doses twice a day, for three days before and three days after the CYP administration. The efficacy of TQ was determined in terms of the protection against the CYP-induced histological perturbations in the bladder tissue, reduction in the oxidative stress, and inhibition of the DNA fragmentation. Immunohistochemistry was performed to examine the expression of Nrf2. TQ protected against CYP-induced oxidative stress was evident from significant reduction in the lipid peroxidation, restoration of the levels of reduced glutathione, catalase and superoxide dismutase activities. TQ treatment significantly reduced the DNA damage evident as reduced DNA fragmentation. A significant decrease in the cellular infiltration, edema, epithelial denudation and hemorrhage were observed in the histological observations. There was restoration and rise in the Nrf2 expression in the bladder tissues of mice treated with TQ. These results confirm that, TQ ameliorates the CYP-induced hemorrhagic cystitis in mice through reduction in the oxidative stress, inhibition of the DNA damage and through increased expression of Nrf2 in the bladder tissues.

BK virus (BKV) hemorrhagic cystitis (HC) is a serious cause of morbidity and mortality after allogeneic hematopoietic SCT (allo-HSCT) in patients with hematological malignancies. Around half of allogenic HSCT patients present with BKV viruria at some point after HSCT; about 5-40% of these patients subsequently develop active HC. Supportive care including bladder irrigation, blood transfusions and symptomatic pain management remains the mainstay of therapy; the acyclic nucleoside analogue cidofovir is currently the front-line drug for BKV-HC treatment. Here we report the first case of severe hemorrhagic cystitis from India who was successfully treated with low dose cidofovir therapy. © Journal of the Association of Physicians of India 2011.

The Uzbek version of the Acute Cystitis Symptom Score (ACSS) was developed as a simple self-reporting questionnaire to improve diagnosis and therapy of women with acute cystitis (AC). The purpose of this work was to validate the ACSS in the German language. The ACSS consists of 18 questions in four subscales: (1) typical symptoms, (2) differential diagnosis, (3) quality of life, and (4) additional circumstances. Translation of the ACSS into German was performed according to international guidelines. For the validation process 36 German-speaking women (age: 18-90 years), with and without symptoms of AC, were included in the study. Classification of participants into two groups (patients or controls) was based on the presence or absence of typical symptoms and significant bacteriuria (≥ 10(3) CFU/ml). Statistical evaluations of reliability, validity, and predictive ability were performed. ROC curve analysis was performed to assess sensitivity and specificity of ACSS and its subscales. The Mann-Whitney's U test and t-test were used to compare the scores of the groups. Of the 36 German-speaking women (age: 40 ± 19 years), 19 were diagnosed with AC (patient group), while 17 women served as controls. Cronbach's α for the German ACSS total scale was 0.87. A threshold score of ≥ 6 points in category 1 (typical symptoms) significantly predicted AC (sensitivity 94.7%, specificity 82.4%). There were no significant differences in ACSS scores in patients and controls compared to the original Uzbek version of the ACSS. The German version of the ACSS showed a high reliability and validity. Therefore, the German version of the ACSS can be reliably used in clinical practice and research for diagnosis and therapeutic monitoring of patients suffering from AC.

Birth-cohort patterns of mortality from ulcerative colitis and peptic ulcer.

PubMed

Sonnenberg, Amnon

2008-10-01

The aim was to follow the time trends of mortality from ulcerative colitis and compare them with those of gastric and duodenal ulcer. Mortality data from 21 different countries between 1941 and 2004 were analyzed. The age-specific death rates of each individual country, as well as the average age-specific rates of all countries, were plotted against the periods of birth and death. The average trends of mortality from ulcerative colitis, gastric and duodenal ulcer reveal distinctive and unique birth-cohort patterns of all three diseases. Similar to both types of peptic ulcer, the risk of developing ulcerative colitis started to rise in successive generations born during the second half of the 19(th) century. It peaked shortly before the turn of the century and has continued to decline since then. The rise and fall in the occurrence of ulcerative colitis preceded those of both ulcer types. The birth-cohort pattern indicates that exposure to the relevant risk factors of ulcerative colitis occurs during early life. As the model of H. pylori and its associated birth-cohort patterns of gastric and duodenal ulcer suggest, an enteric infection provides a possible explanation for such temporal trends of ulcerative colitis as well.

Pathophysiology of wound healing and alterations in venous leg ulcers-review.

Raffetto, Joseph D

2016-03-01

Venous leg ulcer (VLU) is one of the most common lower extremity ulcerated wound, and is a significant healthcare problem with implications that affect social, economic, and the well-being of a patient. VLU can have debilitating related problems which require weekly medical care and may take months to years to heal. The pathophysiology of VLU is complex, and healing is delayed in many patients due to a persistent inflammatory condition. Patient genetic and environmental factors predispose individuals to chronic venous diseases including VLU. Changes in shear stress affecting the glycocalyx are likely initiating events, leading to activation of adhesion molecules on endothelial cells, and leukocyte activation with attachment and migration into vein wall, microcirculation, and in the interstitial space. Multiple chemokines, cytokines, growth factors, proteases and matrix metalloproteinases are produced. The pathology of VLU involves an imbalance of inflammation, inflammatory modulators, oxidative stress, and proteinase activity. Understanding the cellular and biochemical events that lead to the progression of VLU is critical. With further understanding of inflammatory pathways and potential mechanisms, certain biomarkers could be revealed and studied as both involvement in the pathophysiology of VLU but also as therapeutic targets for VLU healing. © The Author(s) 2016.

INTRODUCTION There are few Canadian studies that have assessed prescribing patterns and antibiotic preferences of physicians for acute uncomplicated cystitis. A cross-Canada study of adult women with symptoms of acute cystitis seen by primary care physicians was conducted to determine current management practices and first-line antibiotic choices. METHODS A random sample of 2000 members of The College of Family Physicians of Canada were contacted in April 2002, and were asked to assess two women presenting with new urinary tract symptoms. Physicians completed a standardized checklist of symptoms and signs, indicated their diagnosis and antibiotics prescribed. A urine sample for culture was obtained. RESULTS Of the 418 responding physicians, 246 (58.6%) completed the study and assessed 446 women between April 2002 and March 2003. Most women (412 of 420, for whom clinical information about antibiotic prescriptions was available) reported either frequency, urgency or painful urination. Physicians would have usually ordered a urine culture for 77.0% of the women (95% CI 72.7 to 80.8) and prescribed an antibiotic for 86.9% of the women (95% CI 83.3 to 90.0). The urine culture was negative for 32.8% of these prescriptions. The most commonly prescribed antibiotic was trimethoprim/sulfamethoxazole (40.8%; 95% CI 35.7 to 46.1), followed by fluoroquinolones (27.4%; 95% CI 22.9 to 32.3) and nitrofurantoin (26.6%; 95% CI 22.1 to 31.4). CONCLUSION Empirical antibiotic prescribing is standard practice in the community, but is associated with high levels of unnecessary antibiotic use. While trimethoprim/sulfamethoxazole is the first-line empirical antibiotic choice, fluoroquinolone antibiotics have become the second most commonly prescribed empirical antibiotic for acute cystitis. The effect of current prescribing patterns on community levels of quinolone-resistant Escherichia coli may need to be monitored. PMID:19436509

Hyperbaric Oxygen Treatment in Radiation-Induced Cystitis and Proctitis: A Prospective Cohort Study on Patient-Perceived Quality of Recovery

Oscarsson, Nicklas, E-mail: nicklas.oscarsson@vgregion.se; Arnell, Per; Lodding, Pär

Purpose: In this prospective cohort study, the effects of hyperbaric oxygen treatment (HBOT) were evaluated concerning patient-perceived symptoms of late radiation-induced cystitis and proctitis secondary to radiation therapy for pelvic cancer. Methods and Materials: Thirty-nine patients, 35 men and 4 women with a mean age of 71 (range, 35-84) years were included after informed consent and institutional ethics approval. They had all been treated with radiation therapy for prostate (n=34), cervix (n=2), or rectal (n=3) cancer using external beam radiation at a dose of 25 to 75 Gy. Patients with hematuria requiring blood transfusion were excluded. The HBOT was deliveredmore » with 100% oxygen for 90 minutes at 2.0 to 2.4 atmospheres (ATA). Mean number of treatments was 36 (28-40). Symptoms were prospectively assessed using the Expanded Prostate Index Composite score before, during, and 6 to 12 months after HBOT. Results: The HBOT was successfully conducted, and symptoms were alleviated in 76% for patients with radiation cystitis, 89% for patients with radiation proctitis, and 88% of patients with combined cystitis and proctitis. Symptom reduction was demonstrated by an increased Expanded Prostate Index Composite score in the urinary domain from 50 ± 16 to 66 ± 20 after treatment (P<.001) and in the bowel domain from 48 ± 18 to 68 ± 18 after treatment (P<.001). For 31% of the patients with cystitis and 22% with proctitis, there were only trivial symptoms after HBOT. The improvement was sustained at follow-up in both domains 6 to 12 months after HBOT. No severe side effects were observed related to HBOT, and treatment compliance was high. Conclusions: HBOT can be an effective and safe treatment modality for late radiation therapy-induced soft tissue injuries in the pelvic region.« less

Interstitial laser prostatectomy

Johnson, Douglas E.; Cromeens, Douglas M.; Price, Roger E.

1994-05-01

Interstitial laser coagulation of the canine prostate using the Sharplan interstitial thermal therapy fiber (Model 25432) was performed in 9 adult dogs and the subsequent gross and histopathologic changes occurring in the prostate were studied at intervals ranging from 1 hour to 5 weeks. A large well-demarcated area of acute coagulative necrosis developed around each fiber tract which in turn was surrounded by a prominent narrow zone of marked tissue disruption and an outer zone of hemorrhage. Liquefaction developed within the coagulative areas within 24 hours and by 4 days, each prostatic lobe contained an irregular cavity which became lined by normal-appearing transitional epithelium and that by 5 weeks, communicated with the prostatic urethra. These changes, similar to those reported following transurethral visual laser ablation of the prostate, suggest that interstitial laser thermal therapy may provide an alternative means for treating selected patients suffering from prostatic enlargement.

Advances in the treatment of rheumatic interstitial lung disease.

Vassallo, Robert; Thomas, Charles F

2004-05-01

Interstitial lung disease frequently complicates the rheumatic diseases. The purpose of this review is to outline recent advances and current concepts regarding the management of these interstitial lung diseases. Several histologic lesions cause interstitial lung disease in rheumatic diseases, including nonspecific interstitial pneumonia, usual interstitial pneumonia, organizing pneumonia, lymphocytic interstitial pneumonia, desquamative interstitial pneumonia, and acute interstitial pneumonia. Although the relative frequency of occurrence of these histopathologic lesions is not definitively established, it seems that nonspecific interstitial pneumonia accounts for a large proportion of rheumatic disease-associated interstitial lung diseases. Although usual interstitial pneumonia generally responds poorly to corticosteroid therapy, other forms of interstitial pneumonia are often steroid responsive and have a more favorable long-term prognosis. Pulmonary hypertension is increasingly recognized as a complication of these interstitial lung diseases. Treatment of pulmonary hypertension in these patients provides clinical benefit and may suppress pulmonary inflammation and fibrosis. Lung transplantation is a treatment option for selected patients with severe pulmonary involvement and limited life expectancy. Interstitial lung disease is common in the rheumatic diseases, may be caused by a variety of lesions that respond differently to treatment, and may lead to the development of pulmonary hypertension. Whether the prognosis of interstitial lung disease associated with rheumatic disease is similar to that associated with the idiopathic interstitial pneumonias is not known. Treatment of these interstitial lung diseases should take into account the specific histologic lesion, the activity of the underlying rheumatic disease, and associated pulmonary hypertension, if present. The diagnosis of a rheumatic disease is no longer an absolute contraindication to lung

The results of the treatment of 38 children (6 boys and 32 girls, age 6-14 years) with chronic pyelonephritis and/or cystitis complicated with neurogenic dysfunction of the urinary bladder (NDUB) and/or vesicoureteral reflux (VUR) of the first-third degree demonstrate efficacy of intravesical electrostimulation (IVES) and adrenal magnetotherapy. IVES was conducted with high-frequency current impulses (2.2 kHz) by means of INTRASTIM attachment to the device AMUS-01-INTRAMAG in the region of the urethrovesical anastomosis via solution of the drugs for instillation. As the result of exposure to both physical factors in the presence of standard medication, NDUB symptoms alleviated (by E.L. Vishnevsky's criteria) by 59.5% against 38.1% in the control group. Dopplerographic examination of renal vessels stated a 24.3% increase in blood flow in the major renal artery in the study group against 10.5% in the control. The proposed complex pharmacological plus physiotherapeutic treatment of chronic pyelonephritis and cystitis in abnormal urodynamics resulted in a 2.2-fold decrease in the number of recurrences compared to the standard treatment.

Around 125,785 new cases in year 2013-14 of leprosy were detected in India as per WHO report on leprosy in September 2015 which accounts to approximately 62% of the total new cases. Anaesthetic foot caused by leprosy leads to uneven loading of foot leading to ulcer in approximately 20% of the cases. Much efforts have gone in identifying newer techniques to efficiently monitor the progress of ulcer healing. Current techniques followed in measuring the size of ulcers, have not been found to be so accurate but are still is followed by clinicians across the globe. Quantification of prognosis of the condition would be required to understand the efficacy of current treatment methods and plan for further treatment. This study aims at developing a non contact technique to precisely measure the size of ulcer in patients affected by leprosy. Using MATLAB software, GUI was designed to process the acquired ulcer image by segmenting and calculating the pixel area of the image. The image was further converted to a standard measurement using a reference object. The developed technique was tested on 16 ulcer images acquired from 10 leprosy patients with plantar ulcers. Statistical analysis was done using MedCalc analysis software to find the reliability of the system. The analysis showed a very high correlation coefficient (r=0.9882) between the ulcer area measurements done using traditional technique and the newly developed technique, The reliability of the newly developed technique was significant with a significance level of 99.9%. The designed non-contact ulcer area calculating system using MATLAB is found to be a reliable system in calculating the size of ulcers. The technique would help clinicians have a reliable tool to monitor the progress of ulcer healing and help modify the treatment protocol if needed. Copyright © 2017 European Foot and Ankle Society.

Furagin (a nitrofurantoin analogue) has the same efficacy in treating acute cystitis as ciprofloxacin, however the duration of therapy is longer. We established a hypothesis that therapy with ciprofloxacin results in faster resolution of mucosal inflammation in comparison with furagin. Rates of urinary secretion of immunoglobulins class A, M and G and interleukin-8 (IL-8) were evaluated before and after initiation of therapy in adult women presenting with acute cystitis confirmed by urine culture. Women were randomised into two groups receiving either ciprofloxacin 250mg twice a day for 3 days (n=13) or furagin 100mg three times a day for 7 days (n=14). Median lengths of follow-up were 4 days and 5 days in the ciprofloxacin and furagin groups, respectively. Treatment with ciprofloxacin resulted in faster eradication of pathogens. No bacteria or nitrates were detected in the ciprofloxacin group, whilst leukocyte esterase was positive in only one case. In the furagin group there were four positive cultures, seven cases with positive nitrates and five cases with positive esterase. Secretion rates of all four substances dropped significantly, but the changes over time were similar in both groups.

1997-01-01

The purpose of this study was to describe the types of periosteal reaction seen in response to long-standing leg ulcers and to differentiate the types associated with osteomyelitis. Over a 10-year span, we retrospectively evaluated the radiographs of 20 patients with lower leg soft-tissue ulceration and adjacent periosteal bone reaction of the tibia or fibula. Two of us evaluated the location and appearance of periosteal reaction, and one of us evaluated the patients' medical records for evidence of peripheral vascular disease, systemic illnesses, and osteomyelitis. Twelve patients had organized periosteal reactions that resulted in the appearance of ulcer osteoma. None of these patients subsequently developed osteomyelitis. Eight patients had interrupted lamellar nodular periosteal reactions; six of the eight patients had superimposed osteomyelitis. Our study showed two types of periosteal response to chronic leg ulcers: a solid organized type that over time formed an ulcer osteoma and a lamellar nodular type that was often associated with osteomyelitis. Both types of ulcers were seen in patients with peripheral vascular disease, IV drug abuse, sickle cell disease, and neurologic impairment.

This morphological study aims to investigate the effects of defibrotide, a deoxyribonucleic acid derivative drug with cytoprotective, immunosuppressive and vasorelaxant effects, on protamine sulfate induced bladder injury. Wistar albino female rats were catheterized and intravesically infused with phosphate buffered solution (control group) or, either protamine sulfate (bladder injury group) or protamine sulfate+defibrotide (bladder injury+defibrotide group) dissolved in phosphate buffered solution. The morphology of the urinary bladder was investigated using light and electron microscopy. The number of mast cells in the mucosa, mucosal alterations, intercellular junctions, surface topography and the glycosaminoglycan (GAG) layer as well as microvillus formation on the luminal surface were evaluated. In the bladder injury group, ulcerated areas, irregularity of the GAG layer, increased number of mast cells, vacuole formation, dilated perinuclear cistern, formation of pleomorphic and uniform microvilli and dilatations in the intercellular spaces in the urothelium were observed. In the bladder injury+defibrotide group a relatively normal urothelial topography, GAG layer and a few mast cells in the mucosa, some dilatations between the intercellular areas, less uniform microvilli, regular perinuclear cistern and tight junctions were observed. These results show that defibrotide can inhibit PS induced bladder damage.

Fatal complication of intravesical formalin during control of intractable hemorrhage from radiation cystitis

Rao, M.S.; Singhal, P.C.; Bapna, B.C.

Fatal acute tubular necrosis occurred in 1 patient in whom intravesical formalin was used to control massive persistent hemorrhage from radiation cystitis. A suggestion is made to monitor blood formic acid levels and institute prompt dialysis whenever these exceed 80 mg per 100 ml to avert such a catastrophe. Intravenous sodium bicarbonate appears to be indicated prophylactically in combating the associated metabolic acidosis due to absorbed formic acid.

The objective of this article was to study characteristics of pressure ulcer patients and their ulcers, pressure ulcer preventive and treatment measures in four Indonesian general hospitals. A multicentre cross-sectional design was applied to assess pressure ulcers and pressure ulcer care in adult patients in medical, surgical, specialised and intensive care units. Ninety-one of the 1132 patients had a total of 142 ulcers. Half (44·0%) already had pressure ulcers before admission. The overall prevalence of category I-IV pressure ulcers was 8·0% (95% CI 6·4-9·6), and the overall nosocomial pressure ulcer prevalence was 4·5% (95% CI 3·3-5·7). Most pressure ulcer patients had friction and shear problems, were bedfast, had diabetes and had more bedridden days. Most ulcers (42·3%) were category III and IV. One third of the patients had both pressure ulcers and moisture lesions (36·3%) and suffered from pain (45·1%). The most frequently used prevention measures were repositioning (61·5%), skin moisturising (47·3%), patient education (36·3%) and massage (35·2%). Most pressure ulcer dressings involved saline-impregnated or antimicrobial gauzes. This study shows the complexities of pressure ulcers in Indonesian general hospitals and reveals that the quality of pressure ulcer care (prevention and treatment) could be improved by implementing the recent evidence-based international guideline. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

We have previously demonstrated nerve growth factor (NGF) regulation of pituitary adenylate cyclase-activating polypeptide (PACAP)/receptors in bladder reflex pathways using a transgenic mouse model of chronic NGF overexpression in the bladder using the urothelial-specific uroplakin II promoter. We have now explored the contribution of target-derived NGF in combination with cyclophosphamide (CYP)-induced cystitis to determine whether additional changes in neuropeptides/receptors are observed in micturition reflex pathways due to the presence of additional inflammatory mediators in the urinary bladder. Quantitative PCR was used to determine PACAP/vasoactive intestinal polypeptide (VIP), substance P, galanin, and receptor transcript expression in the urinary bladder (urothelium, detrusor) in mice with overexpression of NGF in the urothelium (NGF-OE) and wild-type (WT) mice with CYP-induced cystitis (4 h, 48 h, and chronic). With CYP-induced cystitis (4 h), WT and NGF-OE mice exhibited similar changes in galanin transcript expression in the urothelium (30-fold increase) and detrusor (threefold increase). In contrast, PACAP, VIP, and substance P transcripts exhibited differential changes in WT and NGF-OE with CYP-induced cystitis. PAC1, VPAC1, and VPAC2 transcript expression also exhibited differential responses in NGF-OE mice that were tissue (urothelium vs. detrusor) and CYP-induced cystitis duration-dependent. Using conscious cystometry, NGF-OE mice treated with CYP exhibited significant (p ≤ 0.01) increases in voiding frequency above that observed in control NGF-OE mice. In addition, no changes in the electrical properties of the major pelvic ganglia neurons of NGF-OE mice were detected using intracellular recording, suggesting that the urinary bladder phenotype in NGF-OE mice is not influenced by changes in the efferent limb of the micturition reflex. These studies are consistent with target-derived NGF and other inflammatory mediators affecting

Cost-effectiveness of wound management in France: pressure ulcers and venous leg ulcers.

This study set out to define realistic protocols of care for the treatment of chronic venous leg ulcers and pressure ulcers in France and, by developing cost-effectiveness models, to compare the different protocols of care for the two ulcer groups, enabling a calculation of direct medical costs per ulcer healed in a typical French health insurance plan. Clinical outcomes and some treatment patterns were obtained from published literature. Validations of different treatment patterns were developed using an expert consensus panel similar to the Delphi approach. Costs were calculated based on national averages and estimates from the UK and Germany. The models were used to measure costs per healed ulcer over a 12-week period. For both the pressure ulcer and venous leg ulcer models, three protocols of care were identified. For pressure ulcers and venous leg ulcers, the hydrocolloid DuoDERM (ConvaTec, also known as Granuflex in the UK and Varihesive in Germany) was most cost-effective in France. The combination of published data and expert consensus opinion is a valid technique, and in this case suggests that treating pressure ulcers and venous leg ulcers with hydrocolloid dressings is more cost-effective than treating them with saline gauze, in spite of the lower unit cost of the latter.

Haemorrhagic cystitis is an uncommon and, in its severe form, potentially life-threatening complication of haematopoietic stem cell transplantation or cancer therapy in children. The severe form involves macroscopic haematuria with blood clots, urinary obstruction and/or renal impairment. There are many therapeutic options to treat acute haemorrhage, but only recombinant factor VII has a high level of clinical evidence in children. Supraselective vesical artery embolization (SVAE) is an increasingly used therapeutic procedure for controlling haemorrhage in adults, but is less commonly used in children. This might be due to several factors, such as the invasive nature of the procedure, lack ofmore » appropriate medical experience and possible long-term side effects. We present three cases of children successfully treated by means of effective SVAE.« less

Interstitial granulomatous dermatitis with arthritis is an uncommon systemic disorder involving the cutaneous and musculoskeletal systems. The eruption may mimic other dermatoses including granuloma annulare, erythema chronicum migrans, and the inflammatory stage of morphea. Key histopathologic characteristics, along with clinical correlation, allow accurate diagnosis. We describe the clinical, serologic, and histologic features in three patients with interstitial granulomatous dermatitis with arthritis. Skin biopsy specimens were examined and correlated with the clinical and laboratory findings. Erythematous, annular, indurated plaques on the extremities were present in two women. An erythematous, papular eruption on the head and neck was present in a third patient. All patients had myalgia and migratory polyarthralgias of the extremities along with various serologic abnormalities. Histologic examination revealed a dense lymphohistiocytic interstitial infiltrate involving primarily the reticular dermis. Foci of necrobiotic collagen were present. Vasculitis was absent. Interstitial granulomatous dermatitis with arthritis is unique multisystem disease with variable cutaneous expression. Abnormal serologic findings indicate a possible connection to collagen vascular disease.

Despite the continually increasing rates of adverse perinatal outcomes across the globe, the molecular mechanisms that underlie adverse perinatal outcomes are not completely understood. Clinical studies report that 10% of pregnant women will experience a urinary tract infection (UTI) and there is an association of UTIs with adverse perinatal outcomes. We introduced bacterial cystitis into successfully outbred female mice at gestational day 14 to follow pregnancy outcomes and immunological responses to determine the mechanisms that underlie UTI-mediated adverse outcomes. Outbred fetuses from mothers experiencing localized cystitis displayed intrauterine growth restriction (20–80%) as early as 48 hours post-infection and throughout the remainder of normal gestation. Robust infiltration of cellular innate immune effectors was observed in the uteroplacental tissue following introduction of UTI despite absence of viable bacteria. The magnitude of serum proinflammatory cytokines is elevated in the maternal serum during UTI. This study demonstrates that a localized infection can dramatically impact the immunological status as well as the function of non-infected distal organs and tissues. This model can be used as a platform to determine the mechanism(s) by which proinflammatory changes occur between non-contiguous genitourinary organs PMID:22470490

Lung transplantation and interstitial lung disease.

2005-09-01

Interstitial lung disease includes a heterogeneous group of disorders that leads to respiratory insufficiency and death in a significant number of patients. Lung transplantation is a therapeutic option in select candidates. The indications, transplant procedure options, and outcomes continue to evolve. Various recipient comorbidities influence the choice of procedure in patients with interstitial lung disease. Single lung transplants are used as the procedure of choice and bilateral transplants are reserved for patients with suppurative lung disease and patients with pulmonary hypertension. Issues unique to patients with interstitial lung disease affect the morbidity, mortality and recurrence of the disease. Lung transplantation is an effective therapy for respiratory failure in interstitial lung disease with survival following transplant being similar to that achieved in transplant recipients with other diseases.

Connective tissue disorders (CTD), which are often also termed collagen vascular diseases, include a number of related inflammatory conditions. Some of these diseases include rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis (scleroderma), localized scleroderma (morphea variants localized to the skin), Sjogren's syndrome, dermatomyositis, polymyositis, and mixed connective tissue disease. In addition to the systemic manifestations of these diseases, there are a number of cutaneous features that make these conditions recognizable on physical exam. Lower extremity ulcers and digital ulcers are an infrequent but disabling complication of long-standing connective tissue disease. The exact frequency with which these ulcers occur is not known, and the cause of the ulcerations is often multifactorial. Moreover, a challenging component of CTD ulcerations is that there are still no established guidelines for their diagnosis and treatment. The morbidity associated with these ulcerations and their underlying conditions is very substantial. Indeed, these less common but intractable ulcers represent a major medical and economic problem for patients, physicians and nurses, and even well organized multidisciplinary wound healing centers.

History of Helicobacter pylori, duodenal ulcer, gastric ulcer and gastric cancer

Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19th century. The environment before the 20th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20th century physician’s believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for “surgical disease” or for “Sippy” diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori

Balance point characterization of interstitial fluid volume regulation.

Dongaonkar, R M; Laine, G A; Stewart, R H; Quick, C M

2009-07-01

The individual processes involved in interstitial fluid volume and protein regulation (microvascular filtration, lymphatic return, and interstitial storage) are relatively simple, yet their interaction is exceedingly complex. There is a notable lack of a first-order, algebraic formula that relates interstitial fluid pressure and protein to critical parameters commonly used to characterize the movement of interstitial fluid and protein. Therefore, the purpose of the present study is to develop a simple, transparent, and general algebraic approach that predicts interstitial fluid pressure (P(i)) and protein concentrations (C(i)) that takes into consideration all three processes. Eight standard equations characterizing fluid and protein flux were solved simultaneously to yield algebraic equations for P(i) and C(i) as functions of parameters characterizing microvascular, interstitial, and lymphatic function. Equilibrium values of P(i) and C(i) arise as balance points from the graphical intersection of transmicrovascular and lymph flows (analogous to Guyton's classical cardiac output-venous return curves). This approach goes beyond describing interstitial fluid balance in terms of conservation of mass by introducing the concept of inflow and outflow resistances. Algebraic solutions demonstrate that P(i) and C(i) result from a ratio of the microvascular filtration coefficient (1/inflow resistance) and effective lymphatic resistance (outflow resistance), and P(i) is unaffected by interstitial compliance. These simple algebraic solutions predict P(i) and C(i) that are consistent with reported measurements. The present work therefore presents a simple, transparent, and general balance point characterization of interstitial fluid balance resulting from the interaction of microvascular, interstitial, and lymphatic function.

Maintenance therapy with sucralfate in duodenal ulcer: genuine prevention or accelerated healing of ulcer recurrence?

PubMed

Bynum, T E; Koch, G G

1991-08-08

We sought to compare the efficacy of sucralfate to placebo for the prevention of duodenal ulcer recurrence and to determine that the efficacy of sucralfate was due to a true reduction in ulcer prevalence and not due to secondary effects such as analgesic activity or accelerated healing. This was a double-blind, randomized, placebo-controlled, parallel groups, multicenter clinical study with 254 patients. All patients had a past history of at least two duodenal ulcers with at least one ulcer diagnosed by endoscopic examination 3 months or less before the start of the study. Complete ulcer healing without erosions was required to enter the study. Sucralfate or placebo were dosed as a 1-g tablet twice a day for 4 months, or until ulcer recurrence. Endoscopic examinations once a month and when symptoms developed determined the presence or absence of duodenal ulcers. If a patient developed an ulcer between monthly scheduled visits, the patient was dosed with a 1-g sucralfate tablet twice a day until the next scheduled visit. Statistical analyses of the results determined the efficacy of sucralfate compared with placebo for preventing duodenal ulcer recurrence. Comparisons of therapeutic agents for preventing duodenal ulcers have usually been made by testing for statistical differences in the cumulative rates for all ulcers developed during a follow-up period, regardless of the time of detection. Statistical experts at the United States Food and Drug Administration (FDA) and on the FDA Advisory Panel expressed doubts about clinical study results based on this type of analysis. They suggested three possible mechanisms for reducing the number of observed ulcers: (a) analgesic effects, (b) accelerated healing, and (c) true ulcer prevention. Traditional ulcer analysis could miss recurring ulcers due to an analgesic effect or accelerated healing. Point-prevalence analysis could miss recurring ulcers due to accelerated healing between endoscopic examinations. Maximum ulcer

Pressure ulcer prevention: an evidence based analysis The cost-effectiveness of prevention strategies for pressure ulcers in long-term care homes in Ontario: projections of the Ontario Pressure Ulcer Model (field evaluation) Management of chronic pressure ulcers: an evidence-based analysis (anticipated pubicstion date - mid-2009) Purpose A pressure ulcer, also known as a pressure sore, decubitus ulcer, or bedsore, is defined as a localized injury to the skin/and or underlying tissue occurring most often over a bony prominence and caused by pressure, shear, or friction, alone or in combination. (1) Those at risk for developing pressure ulcers include the elderly and critically ill as well as persons with neurological impairments and those who suffer conditions associated with immobility. Pressure ulcers are graded or staged with a 4-point classification system denoting severity. Stage I represents the beginnings of a pressure ulcer and stage IV, the severest grade, consists of full thickness tissue loss with exposed bone, tendon, and or muscle. (1) In a 2004 survey of Canadian health care settings, Woodbury and Houghton (2) estimated that the prevalence of pressure ulcers at a stage 1 or greater in Ontario ranged between 13.1% and 53% with nonacute health care settings having the highest prevalence rate (Table 1).

This study investigated the anti-ulcer and ulcer healing potentials of the methanol extract of Musa sapientum peel in the laboratory rats. Methanol extract of the peels on Musa sapientum (MEMS) was evaluated for its anti-ulcer using alcohol-induced, aspirin-induced, and pyloric ligation-induced models, and for its ulcer healing employing acetic acid-induced ulcer models in rats. The findings from this experiment showed that MEMS (50, 100 and 200 mg/kg, b.w.) anti-ulcer and ulcer healing activity (P ≤ 0.05) is dose-dependent. Also, MEMS exhibited healing of the ulcer base in all the treated groups when compared with the control group. The outcomes of this experiment revealed that the anti-ulcer effect of MEMS may be due to its anti-secretory and cyto-protective activity. The healing of the ulcer base might not be unconnected with basic fibroblast growth factors responsible for epithelial regeneration.

In our previous study, the SLCO1B1 521TT genotype and the SLCO1B1*1b haplotype were significantly associated with the risk of peptic ulcer in patients taking low-dose aspirin (LDA). The aim of the present study was to investigate pharmacogenomic profile of LDA-induced peptic ulcer and ulcer bleeding. Patients taking 100 mg of enteric-coated aspirin for cardiovascular diseases and with a peptic ulcer or ulcer bleeding and patients who also participated in endoscopic surveillance were studied. Genome-wide analysis of single nucleotide polymorphisms (SNPs) was performed using the Affymetrix DME Plus Premier Pack. SLCO1B1*1b haplotype and candidate genotypes of genes associated with ulcer bleeding or small bowel bleeding identified by genome-wide analysis were determined using TaqMan SNP Genotyping Assay kits, polymerase chain reaction-restriction fragment length polymorphism, and direct sequencing. Of 593 patients enrolled, 111 patients had a peptic ulcer and 45 had ulcer bleeding. The frequencies of the SLCO1B1*1b haplotype and CHST2 2082 T allele were significantly greater in patients with peptic ulcer and ulcer bleeding compared to the controls. After adjustment for significant factors, the SLCO1B1*1b haplotype was associated with peptic ulcer (OR 2.20, 95% CI 1.24-3.89) and CHST2 2082 T allele with ulcer bleeding (2.57, 1.07-6.17). The CHST2 2082 T allele as well as SLCO1B1*1b haplotype may identify patients at increased risk for aspirin-induced peptic ulcer or ulcer bleeding. © 2014 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Gastroduodenal ulceration in foals.

PubMed

Becht, J L; Byars, T D

1986-07-01

Gastroduodenal ulceration is becoming recognised as an important disease in foals during the first few months of life. Aetiopathogenesis is presumed to be similar to peptic disease in humans associated with back diffusion of hydrogen ions into the mucosa. Many factors have been incriminated as predisposing foals to ulceration but few have been proven. To date, use of non-steroidal anti-inflammatory agents has been the only documented cause of gastroduodenal ulceration in foals. The clustering of affected foals on certain farms suggests an infectious aetiology but attempts to identify a causative organism have been unsuccessful. Four clinical syndromes defined for foals with gastroduodenal ulceration include: silent ulcers, which occur most often in the non-glandular stomach along the margo plicatus and are identified as incidental findings at necropsy; active ulcers which are often manifested by abdominal pain, excessive salivation and bruxism; perforating ulcers which usually result in a severe, diffuse peritonitis; and pyloric or duodenal obstruction from a healing ulcer. General approaches to therapy of a foal with active ulceration consist of reduction of gastric acidity and enhancement of mucosal protection. Antacids and type 2 histamine receptor antagonists are used most often to neutralise or decrease acid secretion, respectively. Sucralfate, a locally active sulphated sucrose preparation, is commonly used as a cytoprotective agent. The efficacy and safety of many products used have not been evaluated adequately in foals. Perforating ulcers are usually associated with death or humane destruction of the foal because of fulminating peritonitis. Surgical intervention and bypass procedures are indicated in foals that develop pyloric or duodenal obstructions from healing ulcers.

We examined the effects of intravesical application of rebamipide (Otsuka Pharmaceutical, Tokyo, Japan) on bladder inflammation and overactivity in a chemically induced cystitis model. Female Sprague Dawley® rats under isoflurane anesthesia were injected with 150 mg/kg cyclophosphamide in the peritoneum, and 1 mM or 10 mM rebamipide or vehicle was administered in the bladder and remained for 1 hour. Control rats were injected with saline in the peritoneum and vehicle was administered in the bladder. The bladder was harvested at 48 hours. Hematoxylin and eosin staining was performed and the inflammation grade was assessed. The amount of myeloperoxidase was measured using enzyme-linked immunosorbent assay. Proinflammatory cytokines were quantified using reverse transcriptase-polymerase chain reaction. Cystometrogram was done in awake rats 48 hours after cyclophosphamide treatment to measure voiding reflex parameters. Histological evaluation revealed that bladder inflammation in cyclophosphamide treated rats was suppressed by rebamipide in a dose dependent manner. Up-regulated myeloperoxidase, IL-1β, IL-6 and TNF-α expression in cyclophosphamide treated rats was also suppressed in rebamipide treated rats. Cystometrogram demonstrated that the intercontraction interval decreased in cyclophosphamide treated rats but was prolonged by rebamipide. Intravesical application of rebamipide suppressed bladder inflammation and overactivity in a dose dependent manner. This may provide a new treatment strategy for chemotherapy associated cystitis.

Long-term bedridden patients are at high risk of acquring pressure ulcers (PUs). In this group of patients, prevention is necessary to cut the health costs, improve quality of life and reduce the mortality. Here, we evaluated the effectiveness of a cross-linked hyaluronic acid (HA) as plastic bulking-agent filling and remodelling the deep dermis and subcutaneous space of the skin areas exposed to the risk of necrosis. Our work hypothesis has been to inflate a sub-dermal elastic cushion, filled with a natural ECM component, with the aim to induce a stronger tissue background resistant to the ulcerative process. All the patients had an increased risk of PUs, at the sacral, ileum or heel skin. Patients were being nursed accordingly to the standard orthopaedic ward management with a pressure relieveing air mattress. The standard protocol consisted in body mobilisation every 3 hours, 24 hours a day and accurate cleaning of the skin with liquid soap and water without any towel friction and without adding any cream or lotion for the skin protection. Our filling protocol enclosed: accurate disinfection of the skin to be injected with povidone-iodine solution, followed by a local anaesthesia with 28G 13 mm needle, injecting 1.5 ml of 1% xylocaine. Then slow, deep, subcutaneous injection of cross-linked HA was performed with a 18G long needle, in order to deliver a homogeneous, soft gel layer underneath and around the whitish erythematous skin edges at risk of ulceration. Patients' tolerability of the compound and adverse events were also recorded. There were 15 patients (78-94 years old) who participated in the study. All tolerated the procedure very well and no serious side effects were declared. No skin pressure ulceration was detected in the four weeks follow-up Conclusion: We have demonstrated the safety and tolerability of a cross-linked HA subdermal injection in PUs prevention. The compound stratifies in a soft, elastic, interstitial bulk into the deep dermis, thus

Chlorella sp. is a green microalgae containing nutrients, vitamins, minerals, and chlorophyll. In some communities, Chlorella sp. is a traditional medicinal plant used for the management of inflammation-related diseases. In a rat model, ROQUETTE Chlorella sp. (RCs) benefits were investigated on visceral pain and associated inflammatory parameters related to cystitis both induced by cyclophosphamide (CYP). RCs was orally administered every day from day 1-16 (250 and 500 mg/kg body weight). Six hours after an intraperitoneal injection of 200 mg/kg body weight of CYP, body temperature, general behavior, food intake, and body weight were recorded. Twenty-four hours after CYP injection, rats were tested in two behavioral tests, an open field and the aversive light stimulus avoidance conditioning test, to evaluate the influence of pain on general activity and learning ability of rats. After euthanasia, bladders were weighed, their thickness was scored, and the urinary hemoglobin was measured. RCs orally administered at the two dosages significantly reduced visceral pain and associated inflammatory parameters related to cystitis both induced by CYP injection, and improved rat behavior. To conclude, RCs demonstrated beneficial effects against visceral pain and cystitis.

Ghana is a Buruli ulcer (BU) endemic country yet there is paucity of socio-cultural research on BU. Examining distinctive experiences and meanings for pre-ulcers and ulcers of BU may clarify the disease burden, illness experience and local perceptions of causes and spread, and environmental features of BU, which are useful to guide public health programmes and future research. This study aimed to explain local meanings and experiences of BU for persons with pre-ulcers and ulcers in the Ga-West and Ga-South municipalities in Accra. Semi-structured interviews based on the Explanatory Model Interview Catalogue framework were administered to 181 respondents comprising 15 respondents with pre-ulcers and 166 respondents with ulcers. The Wilcoxon rank-sum test was used to compare categories of illness experiences (PD) and perceived causes (PC) among respondents with pre-ulcer and ulcer conditions. The Fisher's exact test was used to compare the most troubling PD and the most important PC variables. Qualitative phenomenological analysis of respondents' narratives clarified illness experiences and meanings with reference to PC and PD variables. Families of respondents with pre-ulcers and the respondents themselves were often anxious about disease progression, while families of respondents with ulcers, who had to give care, worried about income loss and disruption of school attendance. Respondents with pre-ulcers frequently reported swimming in ponds and rivers as a perceived cause and considered it as the most important PC (53.3%). Respondents with ulcers frequently attributed their BU illness to witchcraft (64.5%) and respondents who claimed they had no water contact, questioned the credibility of health messages Affected persons with pre-ulcers are likely to delay treatment because of social and financial constraints and the absence of pain.

Interstitial hydraulic conductivity and interstitial fluid pressure for avascular or poorly vascularized tumors.

PubMed

Liu, L J; Schlesinger, M

2015-09-07

A correct description of the hydraulic conductivity is essential for determining the actual tumor interstitial fluid pressure (TIFP) distribution. Traditionally, it has been assumed that the hydraulic conductivities both in a tumor and normal tissue are constant, and that a tumor has a much larger interstitial hydraulic conductivity than normal tissue. The abrupt transition of the hydraulic conductivity at the tumor surface leads to non-physical results (the hydraulic conductivity and the slope of the TIFP are not continuous at tumor surface). For the sake of simplicity and the need to represent reality, we focus our analysis on avascular or poorly vascularized tumors, which have a necrosis that is mostly in the center and vascularization that is mostly on the periphery. We suggest that there is an intermediary region between the tumor surface and normal tissue. Through this region, the interstitium (including the structure and composition of solid components and interstitial fluid) transitions from tumor to normal tissue. This process also causes the hydraulic conductivity to do the same. We introduce a continuous variation of the hydraulic conductivity, and show that the interstitial hydraulic conductivity in the intermediary region should be monotonically increasing up to the value of hydraulic conductivity in the normal tissue in order for the model to correspond to the actual TIFP distribution. The value of the hydraulic conductivity at the tumor surface should be the lowest in value. Copyright © 2015 Elsevier Ltd. All rights reserved.

Epimorphin expression in interstitial pneumonia

Epimorphin modulates epithelial morphogenesis in embryonic mouse organs. We previously suggested that epimorphin contributes to repair of bleomycin-induced pulmonary fibrosis in mice via epithelium-mesenchyme interactions. To clarify the role of epimorphin in human lungs, we evaluated epimorphin expression and localization in normal lungs, lungs with nonspecific interstitial pneumonia (NSIP), and lungs with usual interstitial pneumonia (UIP); we also studied the effect of recombinant epimorphin on cultured human alveolar epithelial cells in vitro. Northern and Western blotting analyses revealed that epimorphin expression in NSIP samples were significantly higher than those in control lungs and lungs with UIP. Immunohistochemistry showed strong epimorphin expression in mesenchymal cells of early fibrotic lesions and localization of epimorphin protein on mesenchymal cells and extracellular matrix of early fibrotic lesions in the nonspecific interstitial pneumonia group. Double-labeled fluorescent images revealed expression of matrix metalloproteinase 2 in re-epithelialized cells overlying epimorphin-positive early fibrotic lesions. Immunohistochemistry and metalloproteinase activity assay demonstrated augmented expression of metalloproteinase induced by recombinant epimorphin in human alveolar epithelial cells. These findings suggest that epimorphin contributes to repair of pulmonary fibrosis in nonspecific interstitial pneumonia, perhaps partly by inducing expression of matrix metalloproteinase 2, which is an important proteolytic factor in lung remodeling.

Rebamipide is used as a topical therapeutic agent for various organs. We examined the healing effects of intravesical rebamipide on damaged urothelium in a rat model of chemically induced cystitis. Hydrochloride was injected in the bladder of female Sprague Dawley® rats to induce cystitis. On days 1 and 4 rebamipide (1 or 10 mM) or vehicle was administered in the bladder and maintained for 1 hour. Histopathology, urothelial permeability, cystometrogram and nociceptive behaviors were evaluated on day 7. Also, tissue rebamipide concentrations after the 1-hour bladder instillation were quantified using high performance liquid chromatography. Intravesically administered rebamipide permeated the bladder, particularly in hydrochloride treated rats, and the pharmacologically effective tissue dose remained for greater than 6 hours. Bladder histological evaluation revealed polymorphological inflammatory cell infiltration and decreased positive staining for uroplakin 3A in hydrochloride treated rats. Scanning electron microscopy showed damaged tight junctions in the hydrochloride group. Evans blue absorption in the bladder wall was increased in hydrochloride treated rats. These findings, which were associated with urothelial injury and increased permeability, were dependently suppressed by the rebamipide treatment dose. Cystometrogram demonstrated that the intercontraction interval was shorter in hydrochloride treated rats but prolonged by rebamipide. The increased nociceptive behaviors observed after intravesical resiniferatoxin administration were also suppressed by rebamipide. Intravesical rebamipide accelerated the repair of damaged urothelium, protected urothelial barrier function and suppressed bladder overactivity and nociception.

Malignant Degeneration of Gastric Ulcer

PubMed Central

Finsterer, H.

1939-01-01

Malignant degeneration is the most serious complication of gastric ulcer. Its recognition is difficult both in the early stage and in advanced cases in which only the evidence of a previous ulcer-cavity, and the radiating folds of the mucous membrane indicate progressive development of carcinoma from an original ulcer. It is impossible to say how often gastric ulcer becomes malignant; one can only state the frequency of ulcer-carcinoma, found in gastric resections. One hundred and forty-one personal cases of ulcer-carcinoma are recorded, and are divided into three groups. Group I: 41 which were diagnosed clinically and at operation as cases of ulcer, but in which histological examination showed incipient cancer. Group II: 55 diagnosed clinically as cases of ulcer, but in which a diagnosis of ulcer-carcinoma was made during operation and afterwards histologically confirmed. Group III: 45 diagnosed both clinically and macroscopically (from the typical folding of the mucous membrane) as cases of ulcer-cancer, in which the cancer had entirely overgrown the ulcer. Therefore in the series of 532 resections for gastric ulcer the frequency of ulcer-carcinoma was 20.9%, or 15.2% if the third group is omitted. In a series of 718 resections for gastric cancer, the frequency of ulcer-carcinoma was 19.6% (or 14.2% if the third group is omitted). The mortality in simple two-third resection of the stomach is low (four deaths in 99 cases = 4%). When the pancreas, liver, colon, or œsophagus, is involved, the resection mortality is high (14 deaths in 42 cases = 33.3%), but even in these cases the operation is justifiable because permanent cures were achieved in a number of cases. The prognosis in cases of ulcer-cancer is very grave. In many cases, judging from the author's own experience, patients suffering from incipient ulcer-cancer—only histologically diagnosed as cancer—die from liver metastases, in spite of radical resection. It will thus be seen that the end-results of

To explore microcirculatory changes within the first 48 hours after admission, to compare them with clinical manifestations of bleeding and to define the dependence of recurrent bleeding from the therapy. The study included 108 patients with ulcerative gastroduodenal bleeding who were treated at the Clinical Hospital #71 for the period 2012-2014. There were 80 (74.1%) men and 28 (25.9%) women. Age ranged 20-87 years (mean 54.4±16.8 years). Patients younger than 45 years were predominant (33.4%). J. Forrest classification (1974) was used in endoscopic characterization of bleeding. Roccal Prognostic Scale for gastroduodenal bleeding was applied in all patients at admission to assess the risk of possible recurrence. Patients were divided into 2 groups. Group 1 included 53 (49.1%) patients without recurrent bleeding; group 2-55 (50.1%) patients who had recurrent bleeding within the first two days of treatment. Investigation of microcirculation showed the role of vegetative component including blood circulation centralization, blood flow slowing, blood cells redistribution providing sufficient blood oxygenation. By the end of the first day we observed pronounced hemodilution, decreased blood oxygenation, blood flow restructuring with its acceleration above 1 ml/s, violation of tissue oxygenation, signs of hypovolemia. These changes were significantly different from group 2 and associated with circulatory decentralization with possible pulmonary microcirculation disturbances and interstitial edema. This processes contribute to disruption of tissue oxygenation. We assume that recurrent bleeding in group 2 was caused by fluid therapy in larger volumes than it was necessary in this clinical situation. Infusion therapy should be significantly reduced for the debut of gastroduodenal ulcerative bleeding. Sedative therapy is advisable to reduce the influence of central nervous system.

Urinary tract infections (UTIs) are the most common bacterial infection in women. Most UTIs are acute uncomplicated cystitis caused by Escherichia coli (86%). This study was undertaken to assess the effectiveness of an association of a cranberry dry extract, D-mannose, a gelling complex composed of the exopolysaccharides produced by Streptococcus thermophilus ST10 (DSM 25246) and tara gum, as well as the 2 microorganisms Lactobacillus plantarum LP01 (LMG P-21021) and Lactobacillus paracasei LPC09 (DSM 24243) in women affected by acute uncomplicated cystitis. Thirty-three premenopausal, nonpregnant women diagnosed with acute uncomplicated cystitis were enrolled in a pilot prospective study and completed the treatment protocol. Subjects were instructed to take 2 doses per day during the first month, and then to continue with 1 sachet per day until the sixtieth day. Nitrites and leukocyte esterase on urine dipstick testing were used as indicators of cystitis, with analysis performed at enrollment, after 30 and 60 days, and after 1 month of follow-up. Typical UTI symptoms, namely dysuria, frequent voiding of small volumes, urinary urgency, suprapubic pain, and gross hematuria were scored 0 to 3 and evaluated at each visit. Positive results for the presence of nitrites and leukocyte esterase were found in 14 and 20 subjects after 30 days and in 9 and 14 women after 60 days, respectively (P<0.001). At the end of the follow-up period, positive results for nitrites and leukocyte esterase were recorded in only 4 and 3 of 24 and 19 subjects (16.7%, P=0.103; 15.8%, P=0.325, respectively), with negative results after 60 days. Typical symptoms of cystitis, specifically dysuria, frequent voiding, urgency, and suprapubic pain were significantly improved as well. No significant differences were recorded in the incidence and severity of hematuria at any visit.

Interstitial space and collagen alterations of the developing rat diaphragm

The effect of growth on the relative interstitial space [%total cross-sectional area (CSA)] and collagen content of the rat diaphragm muscle was examined at postnatal ages of 0, 7, 14, and 21 days as well as in adult males. The proportion of interstitial space relative to total muscle CSA was determined by computerized image analysis of lectin-stained cross sections of diaphragm muscle. To assess collagen content and extent of collagen maturation (i.e., cross-linking), high-pressure liquid chromatography analysis was used to measure hydroxyproline concentration and the nonreducible collagen cross-link hydroxylysylpyridinoline (HP), respectively. At birth, interstitial space accounted for approximately 47% of total diaphragm muscle CSA. During postnatal growth, the relative contribution of interstitial space decreased such that by adulthood the interstitial space accounted for approximately 18% of total muscle CSA. The change in relative interstitial space occurred without a concomitant change in hydroxyproline concentration. However, the concentration of HP markedly increased with age such that the adult diaphragm contained approximately 17 times more HP than at birth. These results indicate that during development the relative CSA occupied by interstitial space decreases as muscle fiber size increases. However, the reduction in relative interstitial space is not associated with a change in collagen concentration. Thus collagen density in the interstitial space may increase with age. It is possible that the observed changes in relative interstitial space and collagen influence the passive length-force properties of the diaphragm.

This population-based nationwide Swedish cohort study included 29,032 patients receiving H pylori eradication therapy after peptic ulcer disease in 2005 to 2013. Predefined time intervals between date of peptic ulcer diagnosis and date of eradication therapy were analyzed in relation to study outcomes. Cox regression provided hazard ratios (HRs) and 95% confidence intervals (95% CIs), adjusted for age, sex, comorbidity, history of ulcer disease, use of ulcerogenic drugs, and use of proton pump inhibitors (PPIs). Compared with eradication therapy within 7 days of peptic ulcer diagnosis, eradication therapy within 8 to 30, 31 to 60, 61 to 365, and >365 days corresponded with HRs of recurrent ulcer of 1.17 (95% CI, 1.08-1.25), 2.37 (95% CI, 2.16-2.59), 2.96 (95% CI, 2.76-3.16), and 3.55 (95% CI, 3.33-3.79), respectively. The corresponding HRs for complicated ulcer were 1.55 (95% CI, 1.35-1.78), 3.19 (95% CI, 2.69-3.78), 4.00 (95% CI, 3.51-4.55), and 6.14, (95% CI, 5.47-6.89), respectively. For gastric cancer the corresponding HRs were .85 (95% CI, .32-2.23), 1.31 (95% CI, .31-5.54), 3.64 (95% CI, 1.55-8.56), and 4.71 (95% CI, 2.36-9.38), respectively. Delays in H pylori eradication therapy after peptic ulcer diagnosis time-dependently increase the risk of recurrent ulcer, even more so for complicated ulcer, starting from delays of 8 to 30 days.

Elevated dynamic plantar pressures are a consistent finding in diabetes patients with peripheral neuropathy with implications for plantar foot ulceration. This meta-analysis aimed to compare the plantar pressures of diabetes patients that had peripheral neuropathy and those with neuropathy with active or previous foot ulcers. Published articles were identified from Medline via OVID, CINAHL, SCOPUS, INFORMIT, Cochrane Central EMBASE via OVID and Web of Science via ISI Web of Knowledge bibliographic databases. Observational studies reporting barefoot dynamic plantar pressure in adults with diabetic peripheral neuropathy, where at least one group had a history of plantar foot ulcers were included. Interventional studies, shod plantar pressure studies and studies not published in English were excluded. Overall mean peak plantar pressure (MPP) and pressure time integral (PTI) were primary outcomes. The six secondary outcomes were MPP and PTI at the rear foot, mid foot and fore foot. The protocol of the meta-analysis was published with PROPSERO, (registration number CRD42013004310). Eight observational studies were included. Overall MPP and PTI were greater in diabetic peripheral neuropathy patients with foot ulceration compared to those without ulceration (standardised mean difference 0.551, 95% CI 0.290-0.811, p<0.001; and 0.762, 95% CI 0.303-1.221, p = 0.001, respectively). Sub-group analyses demonstrated no significant difference in MPP for those with neuropathy with active ulceration compared to those without ulcers. A significant difference in MPP was found for those with neuropathy with a past history of ulceration compared to those without ulcers; (0.467, 95% CI 0.181- 0.753, p = 0.001). Statistical heterogeneity between studies was moderate. Plantar pressures appear to be significantly higher in patients with diabetic peripheral neuropathy with a history of foot ulceration compared to those with diabetic neuropathy without a history of ulceration.

Objective: To investigate the possible protective effect of a single dose of ketamine and the synergistic effect between ketamine and 2-mercaptoethane sulfonate (mesna) against ifosfamide-induced hemorrhagic cystitis. Materials and Methods: 35 adult female wistar rats were divided into five groups and pretreated with ketamine at 10 mg/kg and/or mesna 400 mg/kg 30 minutes before intraperitoneal injection of IFS (400 mg/kg) or with saline (control group). Hemorrhagic cystitis was evaluated 24 hours after IFS injection according to bladder wet weight (BWW), and microscopic changes, i.e. edema, hemorrhage, cellular infiltration, and urothelial desquamation. The markers of oxidative damage including nitric oxide (NO) and malondialdehyde (MDA) levels and the expressions of tumor necrosis factor alpha (TNF-α), interleukin 1-beta (IL-1β), inducible nitric oxide synthase (i-NOS) and endothelial nitric oxide synthase (e-NOS) were also assayed in the bladder tissues. Results: Pretreatment with ketamine alone or ketamine in combination with mesna reduced the IFS-induced increase of BWW (58,47% and 63,33%, respectively, P < 0.05). IFS- induced microscopic alterations were also prevented by ketamine with or without mesna (P < 0.05). In addition, also statistically insignificant, the bladder tissue expressions of IL-1β were lower in ketamine and/or mesna-receiving groups (P > 0,05). The parameters of oxidative stress, the NO and the MDA contents of the bladder tissues of the study groups were not different. Conclusion: The results of the present study suggest that a single dose of ketamine pretreatment attenuates experimental IFS-induced bladder damage. It is therefore necessary to investigate ketamine locally and systematically with various dosing schedulesin order to reduce the bladder damage secondary to oxazaphosphorine-alkylating agents and these results may widen the spectrum of ketamine.

Native interstitial defects in ZnGeN2

NASA Astrophysics Data System (ADS)

Skachkov, Dmitry; Lambrecht, Walter R. L.

2017-10-01

A density functional study is presented of the interstitial Zni, Gei, and Ni in ZnGeN2. Corrections to the band gap are included by means of the LDA+U method. The Zn and Ge interstitials are both found to strongly prefer the larger octahedral site compared to the two types of tetrahedral sites. The Zn interstitial is found to be a shallow double donor, but it has higher energy than previously studied antisite defects. It has a resonance in the conduction band that is Zn-s like. The Ge interstitial is an even higher energy of formation defect and also behaves as a shallow double donor, but it also has a deep level in the gap corresponding to a Ge-s orbital character while the Ge-p forms a resonance in the conduction band. The nitrogen interstitial forms a split-interstitial configuration, as also occurs in GaN. Its electronic levels can be related to that of a N2 molecule. The defect levels in the gap correspond to the πg-like lowest unoccupied molecular orbital of the molecule, which here becomes filled with three electrons in the defect's neutral charge state. They are found to prefer a high-spin configuration in the q =+1 state. The corresponding transition levels are obtained and show that this is an amphoteric trap level occurring in +2 , +1 , 0, and -1 charge states. The two possible sites for this split interstitial, on top of Zn or on top of Ge, differ slightly in N2 bond length. While the Ni defects have the lowest formation energy among the interstitials, it is still higher than that of the antisites. Hence they are not expected to occur in sufficient concentration to affect the intrinsic Fermi level position. In particular, they do not contribute to the unintentional n -type background doping.

A group of 133 patients treated for bleeding peptic ulcer in our Department, is reviewed. Within several hours of admission, all patients underwent upper gastrointestinal tract gastroscopy and obliteration of the bleeding ulcer. Bleeding gastric ulcers were found in 41 patients, and duodenal ulcers in 92 patients. Patients were classified according to the Forrest scale: IA – 11 patients, IB – 49 patients, IIA – 35 patients, lIB – 40 patients. In 126 (94.7%) patients the bleeding was stopped, and 7 required urgent surgery: 3 patients with gastric ulcer underwent gastrectomy, and 4 with duodenal ulcer – truncal vagotomy with pyloroplasty and had the bleeding site underpinned. Fifty-five patients underwent elective surgery: gastrectomy and vagotomy (18 patients with gastric ulcer), highly selective vagotomy (25 patients with duodenal ulcer) and truncal vagotomy and pyloroplasty (12 patients with duodenal ulcer). None of the patients was observed to have recurrent bleeding. PMID:18493453

To compare the clinical outcome of patients presenting with symptoms of uncomplicated cystitis who were seen by a doctor, with patients who were given treatment following a diagnostic algorithm. Randomized controlled trial. Out-of-hours service, Oslo, Norway. Women with typical symptoms of uncomplicated cystitis were included in the trial in the time period September 2010-November 2011. They were randomized into two groups. One group received standard treatment according to the diagnostic algorithm, the other group received treatment after a regular consultation by a doctor. Women (n = 441) aged 16-55 years. Mean age in both groups 27 years. Number of days until symptomatic resolution. No significant differences were found between the groups in the basic patient demographics, severity of symptoms, or percentage of urine samples with single culture growth. A median of three days until symptomatic resolution was found in both groups. By day four 79% in the algorithm group and 72% in the regular consultation group were free of symptoms (p = 0.09). The number of patients who contacted a doctor again in the follow-up period and received alternative antibiotic treatment was insignificantly higher (p = 0.08) after regular consultation than after treatment according to the diagnostic algorithm. There were no cases of severe pyelonephritis or hospital admissions during the follow-up period. Using a diagnostic algorithm is a safe and efficient method for treating women with symptoms of uncomplicated cystitis at an out-of-hours service. This simplification of treatment strategy can lead to a more rational use of consultation time and a stricter adherence to National Antibiotic Guidelines for a common disorder.

Late glaucoma after interstitial keratitis.

PubMed

Grant, W M

1975-01-01

In a systematic study of 45 patients who had syphilitic interstitial keratitis early in life and, many years later, were discovered to have glaucoma, there was evidence of two different but equally common mechanisms. In one group of patients, a deep-chamber type of glaucoma was superimposed on old inflammatory changes, was characteristically refractory to medical treatment, but did well with filtering surgery. The other group of patients had reversible angle-closure glaucoma associated with anatomically small anterior segments, and typically responded well to iridectomy. The late, refractory, deep-chamber type of glaucoma may involve endothelialization and formation of glass membrane in the angle, as seen in one excised eye. Occurrence of the shallow-chamber, reversible angle-closure type of glaucoma after interstitial keratitis may be coincidental, since no other evidence supports the idea that small anterior segments might be particularly prevalent among patients who have had congenital syphilis or interstitial keratitis.

2016-01-01

To measure the prevalence of incontinence in the 2013-2014 International Pressure Ulcer Prevalence (IPUP) surveys and determine the relative risk of developing a facility-acquired pressure ulcers (FAPUs) by stage and by Braden Scale score groupings. The IPUP survey is an observational, cross-sectional cohort database designed to determine the frequency and severity of pressure ulcers in various populations. The survey includes acute care (91.4%), long-term acute care (1.7%), rehabilitation patients (1.7%) and long-term care residents (5.2%). Geographic distribution included 182,832 patients in the United States, 22,282 patients in Canada, and the rest of the world, primarily in Europe and the Middle East. We analyzed data from the 2013 and 2014 IPUP surveys to better understand the relationship between incontinence and the frequency and severity of FAPUs. The IPUP survey is an annual voluntary survey of patients who are hospitalized or who reside in long-term care facilities. Data were collected over a 24-hour period within each participating facility. Data collection included limited demographics, presence and stage of pressure ulcers, and pressure ulcer risk assessment score (Braden Scale for Pressure Sore Risk, Braden Q, Norton, Waterlow, and others). In addition, data were collected on pertinent pressure ulcer risk factors including the number of linen layers, use of a pressure redistributing surface, adherence to repositioning schedule, and whether moisture management was provided in the last 24 hours. We aggregated data by urinary, urinary catheter, fecal, fecal management system, double (urinary and fecal), and ostomy incontinence category. If patients were managed by indwelling urinary catheter or fecal management systems, they were considered incontinent in this analysis. In order to analyze ulcers likely to be affected by incontinence, we defined a subset of ulcers as Relevant Pressure Ulcers, which are ulcers that are facility-acquired, non

Interstitial Cells: Regulators of Smooth Muscle Function

PubMed Central

Sanders, Kenton M.; Ward, Sean M.; Koh, Sang Don

2014-01-01

Smooth muscles are complex tissues containing a variety of cells in addition to muscle cells. Interstitial cells of mesenchymal origin interact with and form electrical connectivity with smooth muscle cells in many organs, and these cells provide important regulatory functions. For example, in the gastrointestinal tract, interstitial cells of Cajal (ICC) and PDGFRα+ cells have been described, in detail, and represent distinct classes of cells with unique ultrastructure, molecular phenotypes, and functions. Smooth muscle cells are electrically coupled to ICC and PDGFRα+ cells, forming an integrated unit called the SIP syncytium. SIP cells express a variety of receptors and ion channels, and conductance changes in any type of SIP cell affect the excitability and responses of the syncytium. SIP cells are known to provide pacemaker activity, propagation pathways for slow waves, transduction of inputs from motor neurons, and mechanosensitivity. Loss of interstitial cells has been associated with motor disorders of the gut. Interstitial cells are also found in a variety of other smooth muscles; however, in most cases, the physiological and pathophysiological roles for these cells have not been clearly defined. This review describes structural, functional, and molecular features of interstitial cells and discusses their contributions in determining the behaviors of smooth muscle tissues. PMID:24987007

The pathophysiology of peptic ulcer disease.

PubMed

Brooks, F P

1985-11-01

Heterogeneity is the most important consideration in the pathophysiology of peptic ulcer disease. Acute ulcers and erosions present clinically with gastrointestinal bleeding or perforation. If they heal there is no predictable recurrence. Factors concerned with mucosal defense are relatively more important than aggressive factors such as acid and pepsin. Local ischemia is the earliest recognizable gross lesion. The gastric mucosa is at least as vulnerable as the duodenal mucosa and probably more so. Most drug-induced ulcers occur in the stomach. Chronic or recurrent true peptic ulcers (penetrating the muscularis mucosae) usually present with abdominal pain. Many duodenal ulcer patients report that the pain occurs when the stomach is empty or is relieved by food, and follows a pattern of relatively long periods of freedom from symptoms between recurrences. Approximately 50% of patients experience a recurrence within a year if anti-ulcer medication is stopped. In most western countries recurrent duodenal ulcer is more common than gastric ulcer. Peptic ulcer disease is also more common in men. Recent evidence indicates genetic and familial factors in duodenal ulcer and increased acid-pepsin secretion in response to a variety of stimuli. However, it is also becoming clear that of all the abnormal functions noted, few are present in all subjects and many are clustered in subgroups. In chronic gastric ulcer of the corpus, defective defense mechanisms, such as duodenogastric reflux and atrophic gastritis, seem to be more important than aggressive factors. Nevertheless, antisecretory medications accelerate the healing of such ulcers. It remains to be seen whether prostaglandins, mucus secretion, or gastric mucosal blood flow are impaired in chronic ulcer disease.

[Drug-induced oral ulcerations].

Madinier, I; Berry, N; Chichmanian, R M

2000-06-01

Different side effects of drugs have been described in the oral cavity, including oral ulcerations. Direct contact between drugs and oral mucosa may induce chemical burn or local hypersensitivity. Less frequently, these drug-induced oral ulcerations are part of a complex reaction with cutaneous or systemic manifestations. Sometimes, one or more oral ulcerations appear as the main side-effect of a drug, or exceptionally as solitary lesions. Solitary oral ulcerations usually appear after few weeks of treatment. In most of cases, these lesions resist to conventional treatments, with a rapid healing following the suppression of the responsible drug. This diagnosis is usually difficult, particularly with patients receiving multiple drug therapy. Besides, special attention must be paid to new drugs. Oral ulcerations following symptoms of burning mouth, metallic taste, dysgueusia or agueusia are strongly suggestive of a pharmacological origin. Most of the molecules able to induce solitary oral ulcerations are commonly prescribed in a) rheumatology: NSAI (diclofenac, flurbiprofen, indomethacin, naproxen), long-term rheumatoid arthritis therapy (azathioprine, methotrexate, penicillamine, gold compounds, tiopronin); b) cardiology: angiotensin-converting-enzyme inhibitors (captopril, enalapril), angiotensin 2-receptor antagonist (losartan), anti-angorous (nicorandil), c) psychiatry: antidepressants (fluoxetine, lithium), d) AIDS therapy (foscarnet, zalcitabine).

New insights into canted spiro carbon interstitial in graphite

NASA Astrophysics Data System (ADS)

EL-Barbary, A. A.

2017-12-01

The self-interstitial carbon is the key to radiation damage in graphite moderator nuclear reactor, so an understanding of its behavior is essential for plant safety and maximized reactor lifetime. The density functional theory is applied on four different graphite unit cells, starting from of 64 carbon atoms up to 256 carbon atoms, using AIMPRO code to obtain the energetic, athermal and mechanical properties of carbon interstitial in graphite. This study presents first principles calculations of the energy of formation that prove its high barrier to athermal diffusion (1.1 eV) and the consequent large critical shear stress (39 eV-50 eV) necessary to shear graphite planes in its presence. Also, for the first time, the gamma surface of graphite in two dimensions is calculated and found to yield the critical shear stress for perfect graphite. Finally, in contrast to the extensive literature describing the interstitial of carbon in graphite as spiro interstitial, in this work the ground state of interstitial carbon is found to be canted spiro interstitial.

Venous leg ulcers

2011-01-01

Introduction Leg ulcers usually occur secondary to venous reflux or obstruction, but 20% of people with leg ulcers have arterial disease, with or without venous disorders. Between 1.5 and 3.0/1000 people have active leg ulcers. Prevalence increases with age to about 20/1000 in people aged over 80 years. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of standard treatments, adjuvant treatments, and organisational interventions for venous leg ulcers? What are the effects of advice about self-help interventions in people receiving usual care for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2011 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 101 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: compression bandages and stockings, cultured allogenic (single or bilayer) skin replacement, debriding agents, dressings (cellulose, collagen, film, foam, hyaluronic acid-derived, semi-occlusive alginate), hydrocolloid (occlusive) dressings in the presence of compression, intermittent pneumatic compression, intravenous prostaglandin E1, larval therapy, laser treatment (low-level), leg ulcer clinics, multilayer elastic system, multilayer elastomeric (or non-elastomeric) high-compression regimens or bandages, oral treatments (aspirin, flavonoids

Executive Summary In April 2008, the Medical Advisory Secretariat began an evidence-based review of the literature concerning pressure ulcers. Please visit the Medical Advisory Secretariat Web site, http://www.health.gov.on.ca/english/providers/program/mas/tech/tech_mn.html to review these titles that are currently available within the Pressure Ulcers series. Pressure ulcer prevention: an evidence based analysis The cost-effectiveness of prevention strategies for pressure ulcers in long-term care homes in Ontario: projections of the Ontario Pressure Ulcer Model (field evaluation) Management of chronic pressure ulcers: an evidence-based analysis Objective The Medical Advisory Secretariat (MAS) conducted a systematic review on interventions used to treat pressure ulcers in order to answer the following questions: Do currently available interventions for the treatment of pressure ulcers increase the healing rate of pressure ulcers compared with standard care, a placebo, or other similar interventions? Within each category of intervention, which one is most effective in promoting the healing of existing pressure ulcers? Background A pressure ulcer is a localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in conjunction with shear and/or friction. Many areas of the body, especially the sacrum and the heel, are prone to the development of pressure ulcers. People with impaired mobility (e.g., stroke or spinal cord injury patients) are most vulnerable to pressure ulcers. Other factors that predispose people to pressure ulcer formation are poor nutrition, poor sensation, urinary and fecal incontinence, and poor overall physical and mental health. The prevalence of pressure ulcers in Ontario has been estimated to range from a median of 22.1% in community settings to a median of 29.9% in nonacute care facilities. Pressure ulcers have been shown to increase the risk of mortality among geriatric patients by

Peptic ulcer disease.

Lanas, Angel; Chan, Francis K L

2017-08-05

The rapidly declining prevalence of Helicobacter pylori infection and widespread use of potent anti-secretory drugs means peptic ulcer disease has become substantially less prevalent than it was two decades ago. Management has, however, become more challenging than ever because of the threat of increasing antimicrobial resistance worldwide and widespread use of complex anti-thrombotic therapy in the ageing population. Peptic ulcers not associated with H pylori infection or the use of non-steroidal anti-inflammatory drugs are now also imposing substantial diagnostic and therapeutic challenges. This Seminar aims to provide a balanced overview of the latest advances in the pathogenetic mechanisms of peptic ulcers, guidelines on therapies targeting H pylori infection, approaches to treatment of peptic ulcer complications associated with anti-inflammatory analgesics and anti-thrombotic agents, and the unmet needs in terms of our knowledge and management of this increasingly challenging condition.

2014-09-01

Chronic leg ulcers caused by venous disease, arterial disease or a combination of both need to be clearly identified before treatment can be commenced. Their management will depend on the diagnosis, combining direct management of the ulcer as well as management of patient factors. Other chronic wounds commonly observed in practice include pressure wounds, skin tears, atypical leg ulcers. This paper will outline a simple way to manage people with chronic ulcers. Conclusion The prevalence of chronic wounds is expected to rise given that people are living longer and that the incidence of diabetes is increasing. There is a need is to clearly identify the underlying cause of any wound, including factors that may delay healing, and to treat appropriately. Treatment should address the wound environment, tissue base, presence of bacteria and the level of slough. If there is no improvement in wound healing after 4 weeks then seek help from a wound specialist. The prevalence of chronic ulcers in Australia has been estimated at 2-5%. Comprehensive assessment of the ulcer, the region and the whole person is an important first step in treatment. The aim of management is to promote healing and minimise the impact on the patient.

A low curability of ulcers infected with Candida has been reported in the literature. The aim of the study reported here was to investigate experimentally whether Candida infection affects the healing of ulcers. Candida albicans (the Candida group) or saline (the control group) was administered intragastrically into rats with a cysteamine-induced duodenal ulcer. The duodenal lesions, vascular endothelial growth factor A (VEGF-A) and proliferating cell nuclear antigen (PCNA) were assessed. On Day 7 post-administration, 70.4% rats of the Candida group had a duodenal ulcer compared with 33.3% in the control group (P < 0.05). The duodenal ulcer in the Candida group was significantly larger and deeper than that in the control group. The number of VEGF-A- and PCNA-positive cells was smaller and the area of VEGF-A expression was lower in the Candida group. Using a rat model, we have demonstrated that Candida infection can delay the wound healing process of duodenal ulcers by means of a low expression of VEGF-A and PCNA.

Fatal hemorrhagic cystitis induced by pelvic irradiation and cyclophosphamide therapy. Case reports and review

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

Price, W.E.; Keldahl, L.R.

The potent cytotoxic drug cyclophosphamide has been used extensively for neoplastic and non-neoplastic diseases. Patients taking this drug may have received or may be receiving pelvic irradiation concurrently. This report describes two patients who developed fatal hemorrhagic cystitis induced by pelvic irradiation and cyclophosphamide therapy. Etiology, incidence, pathologic descriptions, and diagnostic and therapeutic aspects of this entity are described. The incidence and risk of serious, life-threatening bladder hemorrhage from cyclophosphamide therapy is increased by prior or concurrent pelvic irradiation. Alternative cytotoxic, non-urotoxic chemotherapy should be used in these high-risk patients.

Interstitial Photoacoustic Sensor for the Measurement of Tissue Temperature during Interstitial Laser Phototherapy

PubMed Central

Photothermal therapy is an effective means to induce tumor cell death, since tumor tissue is more sensitive to temperature increases than normal tissue. Biological responses depend on tissue temperature; target tissue temperature needs to be precisely measured and controlled to achieve desired thermal effects. In this work, a unique photoacoustic (PA) sensor is proposed for temperature measurement during interstitial laser phototherapy. A continuous-wave laser light and a pulsed laser light, for photothermal irradiation and photoacoustic temperature measurement, respectively, were delivered to the target tissue through a fiber coupler. During laser irradiation, the PA amplitude was measured. The Grüneisen parameter and the bioheat equation were used to determine the temperature in strategic positions in the target tissue. Our results demonstrate that the interstitial PA amplitude is a linear function of temperature in the range of 22 to 55 °C, as confirmed by thermocouple measurement. Furthermore, by choosing appropriate laser parameters, the maximum temperature surrounding the active diffuse fiber tip in tissue can be controlled in the range of 41 to 55 °C. Thus, this sensor could potentially be used for fast, accurate, and convenient three-dimensional temperature measurement, and for real-time feedback and control of interstitial laser phototherapy in cancer treatment.

The number of patients who contacted a doctor again in the follow-up period and received alternative antibiotic treatment was insignificantly higher (p = 0.08) after regular consultation than after treatment according to the diagnostic algorithm. There were no cases of severe pyelonephritis or hospital admissions during the follow-up period. Conclusion. Using a diagnostic algorithm is a safe and efficient method for treating women with symptoms of uncomplicated cystitis at an out-of-hours service. This simplification of treatment strategy can lead to a more rational use of consultation time and a stricter adherence to National Antibiotic Guidelines for a common disorder. PMID:25961367

Pressure ulcers continue to be a significant problem in hospitals, nursing homes and community care settings. Pressure ulcer incidence is widely accepted as an indicator for the quality of care. Negative attitudes towards pressure ulcer prevention may result in suboptimal preventive care. A reliable and valid instrument to assess attitudes towards pressure ulcer prevention is lacking. Development and psychometric evaluation of the Attitude towards Pressure ulcer Prevention instrument (APuP). Prospective psychometric instrument validation study. A literature review was performed to design the instrument. Content validity was evaluated by nine European pressure ulcer experts and five experts in psychometric instrument validation in a double Delphi procedure. A convenience sample of 258 nurses and 291 nursing students from Belgium and The Netherlands participated in order to evaluate construct validity and stability reliability of the instrument. The data were collected between February and May 2008. A factor analysis indicated the construct of a 13 item instrument in a five factor solution: (1) attitude towards personal competency to prevent pressure ulcers (three items); (2) attitude towards the priority of pressure ulcer prevention (three items); (3) attitude towards the impact of pressure ulcers (three items); (4) attitude towards personal responsibility in pressure ulcer prevention (two items); and (5) attitude towards confidence in the effectiveness of prevention (two items). This five factor solution accounted for 61.4% of the variance in responses related to attitudes towards pressure ulcer prevention. All items demonstrated factor loadings over 0.60. The instrument produced similar results during stability testing [ICC=0.88 (95% CI=0.84-0.91, P<0.001)]. For the total instrument, the internal consistency (Cronbachs alpha) was 0.79. The APuP is a psychometrically sound instrument that can be used to effectively assess attitudes towards pressure ulcer prevention

Prevention of hospital-acquired pressure ulcers requires the implementation of evidence-based interventions. A quality improvement project was conducted to provide nurses with data on the frequency with which pressure ulcer prevention interventions were performed as measured by documentation. Documentation reports provided feedback to stakeholders, triggering reminders and reeducation. Intervention reports and modifications to the documentation system were effective both in increasing the documentation of pressure ulcer prevention interventions and in decreasing the number of avoidable hospital-acquired pressure ulcers.

There is an enigma of inflammatory bowel diseases, despite significant advantages during last 10 years in medicamentous and surgical treatment. Ulcerative colitis and Crohns disease are chronic with remissions and recidives. Crohns disease involves any part of digestive tube. Histological changes in ulcerative colitis are: inflammation of mucosa and submucosal tissue, crypt abscesses and ulcerations, pseudopolpys, bowel shortening and toxic megacolon in severe inflammation. In Crohns disease, transmural inflammation, "jumping lesions", deeper ulcerations, coble-stone mucosa, progressive fibrosis, granuloma with gigantic epithelial cells. ulcerative colitis: mesalazine, rectal 5-ASA and hydrocortisone enemas, surgery. Crohns disease: mesalazine and prednisolone. For terminal ilcitis, corticosteroid budesonid could be applied. Severe symptomatic disease: hospitalization, parenteral nutrition, antibiotics, prednisone, surgery in partial bowel obstruction, fistulas, abscessus, perforation.

The Pathogenesis of Peptic Ulcer

PubMed Central

Cox, Alvin J.

1955-01-01

Peptic ulcers of the stomach and duodenum look much alike and the reaction around them is nonspecific, yet other evidence indicates that ulcers in the two locations do not represent the same disease. It is suggested that a common causal factor is the digestive effect of gastric juice, and that hypersecretion may produce duodenal ulcer without any predisposing change in the relatively susceptible duodenum. The development of a gastric ulcer, which may occur without hypersecretion, presumably requires some previous alteration of the normally resistant gastric mucosa. Focal metaplasia of the gastric mucosa to tissue resembling the lining of the small intestine, which is observed frequently in association with gastric ulcer, may be a factor in providing decreased resistance to peptic injury.

The evolution of magnetic anisotropy in bcc Fe as a function of interstitial boron atoms was investigated in thin films grown by molecular beam epitaxy. The thermodynamic nonequilibrium conditions during film growth allowed one to stabilize an interstitial boron content of about 14 at .% accompanied by lattice tetragonalization. The c /a ratio scaled linearly with the boron content up to a maximum value of 1.05 at 300 °C substrate growth temperature, with a room-temperature magnetization of. In contrast to nitrogen interstitials, the magnetic easy axis remained in-plane with an anisotropy of approximately -5.1 ×106erg /cm3 . Density functional theory calculations using the measured lattice parameters confirm this value and show that boron local ordering indeed favors in-plane magnetization. Given the increased temperature stability of boron interstitials as compared to nitrogen interstitials, this study will help to find possible ways to manipulate boron interstitials into a more favorable local order.

The available operative procedures for perforated gastric ulcer are gastrectomy, ulcer excision and omental patch closure. This study analysed the outcome of these operative options in a single institution. Seventy-two patients (mean age 43 years, 62 males) with perforated gastric ulcers were managed by laparotomy. There were 34 lesser curve (incisural) and 38 antral ulcers. Partial gastrectomy was performed in 27 patients, ulcer excision in 27 and simple patch closure in 18. Two ulcers were malignant. The mortality rate was 18% (26% for gastrectomy, 19% for ulcer excision and 5% for patch closure). Shock on admission (p = 0.006) and Candida (p = 0.020) in the histological specimen were predictive of poor outcome. Hospital stay was similar in the 3 groups. Omental patch closure and ulcer excision are as effective as gastrectomy in the management of perforated gastric ulcer and merit consideration as first-line therapy in technically applicable cases.

Transient enhanced diffusion (TED) and electrical activation after nonamorphizing Si implantations into lightly B-doped Si multilayers shows two distinct timescales, each related to a different class of interstitial defect. At 700°C, ultrafast TED occurs within the first 15 s with a B diffusivity enhancement of > 2 × 10 5. Immobile clustered B is present at low concentration levels after the ultrafast transient and persists for an extended period (˜ 10 2-10 3 s). The later phase of TED exhibits a near-constant diffusivity enhancement of ≈ 1 × 10 4, consistent with interstitial injection controlled by dissolving {113} interstitial clusters. The relative contributions of the ultrafast and regular TED regimes to the final diffusive broadening of the B profile depends on the proportion of interstitials that escape capture by {113} clusters growing within the implant damage region upon annealing. Our results explain the ultrafast TED recently observed after medium-dose B implantation. In that case there are enough B atoms to trap a large proportion of interstitials in SiB clusters, and the remaining interstitials contribute to TED without passing through an intermediate {113} defect stage. The data on the ultrafast TED pulse allows us to extract lower limits for the diffusivities of the Si interstitial ( DI > 2 × 10 -10 cm 2s -1) and the B interstitial(cy) defect ( DBi > 2 × 10 -13 cm 2s -1) at 700°C.

In biofilms, the matrix of extracellular polymeric substances (EPSs) retains water in the interstitial region of the EPS. This interstitial water is the ambient environment for microorganisms in the biofilms. The nutrient condition in the interstitial water may affect microbial activity in the biofilms. In the present study, we measured the concentrations of dissolved organic nutrients, i.e., saccharides and proteins, contained in the interstitial water of biofilms formed on the stones. We also analyzed the molecular weight distribution, chemical species, and availability to bacteria of some saccharides in the interstitial water. Colorimetric assays showed that the concentrations of saccharides and proteins in the biofilm interstitial water were significantly higher (ca. 750 times) than those in the surrounding lake waters (p < 0.05). Chromatographic analyses demonstrated that the saccharides in the interstitial waters were mainly of low molecular-weight saccharides such as glucose and maltose, while proteins in the interstitial water were high molecular-weight proteins (over 7000 Da). Bacterial growth and production of EPS occurred simultaneously with the decrease in the low molecular-weight saccharide concentrations when a small portion of biofilm suspension was inoculated to the collected interstitial water, suggesting that the dissolved saccharides in the interstitial water support bacterial growth and formation of biofilms.

Deaths from peptic ulcer disease overcome other common emergency situations. Laparoscopic repair of the perforated peptic ulcer (PPU) is the gold standard approach for simple perforation. However, in patients with large perforated chronic ulcers laparotomy with pyloroplasty is the standard treatment. It is generally accepted to perform open surgery in PPU emergencies because of the greater knowledge and experience gathered over the past decades and less potential harm for the patient or surgical complications.

To explore the quality/comprehensiveness of nursing documentation of pressure ulcers and to investigate the relationship between the nursing documentation and the incidence of pressure ulcers in four intensive care units. Pressure ulcer prevention requires consistent assessments and documentation to decrease pressure ulcer incidence. Currently, most research is focused on devices to prevent pressure ulcers. Studies have rarely considered the relationship among pressure ulcer risk factors, incidence and nursing documentation. Thus, a study to investigate this relationship is needed to fill this information gap. A retrospective, comparative, descriptive, correlational study. A convenience sample of 196 intensive care units patients at the selected medical centre comprised the study sample. All medical records of patients admitted to intensive care units between the time periods of September 1, 2011 through September 30, 2012 were audited. Data used in the analysis included 98 pressure ulcer patients and 98 non-pressure ulcer patients. The quality and comprehensiveness of pressure ulcer documentation were measured by the modified European Pressure Ulcer Advisory Panel Pressure Ulcers Assessment Instrument and the Comprehensiveness in Nursing Documentation instrument. The correlations between quality/comprehensiveness of pressure ulcer documentation and incidence of pressure ulcers were not statistically significant. Patients with pressure ulcers had longer length of stay than patients without pressure ulcers stay. There were no statistically significant differences in quality/comprehensiveness scores of pressure ulcer documentation between dayshift and nightshift. This study revealed a lack of quality/comprehensiveness in nursing documentation of pressure ulcers. This study demonstrates that staff nurses often perform poorly on documenting pressure ulcer appearance, staging and treatment. Moreover, nursing documentation of pressure ulcers does not provide a complete

The Significance of Interstitial Cells in Neurogastroenterology

Smooth muscle layers of the gastrointestinal tract consist of a heterogeneous population of cells that include enteric neurons, several classes of interstitial cells of mesenchymal origin, a variety of immune cells and smooth muscle cells (SMCs). Over the last number of years the complexity of the interactions between these cell types has begun to emerge. For example, interstitial cells, consisting of both interstitial cells of Cajal (ICC) and platelet-derived growth factor receptor alpha-positive (PDGFRα+) cells generate pacemaker activity throughout the gastrointestinal (GI) tract and also transduce enteric motor nerve signals and mechanosensitivity to adjacent SMCs. ICC and PDGFRα+ cells are electrically coupled to SMCs possibly via gap junctions forming a multicellular functional syncytium termed the SIP syncytium. Cells that make up the SIP syncytium are highly specialized containing unique receptors, ion channels and intracellular signaling pathways that regulate the excitability of GI muscles. The unique role of these cells in coordinating GI motility is evident by the altered motility patterns in animal models where interstitial cell networks are disrupted. Although considerable advances have been made in recent years on our understanding of the roles of these cells within the SIP syncytium, the full physiological functions of these cells and the consequences of their disruption in GI muscles have not been clearly defined. This review gives a synopsis of the history of interstitial cell discovery and highlights recent advances in structural, molecular expression and functional roles of these cells in the GI tract.

A 14-year-old girl with Fanconi anemia was submitted to allogeneic hematopoietic stem cell transplantation. After 17 days she developed hemorrhagic cystitis due to polyoma BK virus (BKV), confirmed by PCR (polymerase chain reaction). Two weeks after the appearance of the urinary symptoms the patient presented numerous papules and vesicles on both hands and feet. PCR of the skin lesions and plasma was positive for BKV. The relationship of BKV with frequent infections in immunocompromised patients is well established. The positive PCR of vesicular fluid suggests that this was the causative agent of the skin lesion in this case. There are no reports of skin lesions with positive PCR for BKV. © 2011 Wiley Periodicals, Inc.

Cigarette smoking is associated with emphysema and radiographic interstitial lung abnormalities. The degree to which interstitial lung abnormalities are associated with reduced total lung capacity and the extent of emphysema is not known. We looked for interstitial lung abnormalities in 2416 (96%) of 2508 high-resolution computed tomographic (HRCT) scans of the lung obtained from a cohort of smokers. We used linear and logistic regression to evaluate the associations between interstitial lung abnormalities and HRCT measurements of total lung capacity and emphysema. Interstitial lung abnormalities were present in 194 (8%) of the 2416 HRCT scans evaluated. In statistical models adjusting for relevant covariates, interstitial lung abnormalities were associated with reduced total lung capacity (-0.444 liters; 95% confidence interval [CI], -0.596 to -0.292; P<0.001) and a lower percentage of emphysema defined by lung-attenuation thresholds of -950 Hounsfield units (-3%; 95% CI, -4 to -2; P<0.001) and -910 Hounsfield units (-10%; 95% CI, -12 to -8; P<0.001). As compared with participants without interstitial lung abnormalities, those with abnormalities were more likely to have a restrictive lung deficit (total lung capacity <80% of the predicted value; odds ratio, 2.3; 95% CI, 1.4 to 3.7; P<0.001) and were less likely to meet the diagnostic criteria for chronic obstructive pulmonary disease (COPD) (odds ratio, 0.53; 95% CI, 0.37 to 0.76; P<0.001). The effect of interstitial lung abnormalities on total lung capacity and emphysema was dependent on COPD status (P<0.02 for the interactions). Interstitial lung abnormalities were positively associated with both greater exposure to tobacco smoke and current smoking. In smokers, interstitial lung abnormalities--which were present on about 1 of every 12 HRCT scans--were associated with reduced total lung capacity and a lesser amount of emphysema.

Nonspecific interstitial pneumonitis (NSIP) initially described by Katzenstein and Fiorelli in 1994, seems to be a distinct clinicopathologic entity among idiopathic interstitial pneumonitis (IIP). Besides different histologic features from other IIP, NSIP is characterized by a better long-term outcome, associated with a better steroids responsiveness than idiopathic pulmonar fibrosis (IPF), where usually were included. Thus, differentiating NSIP from other IIP, namely IPF is very significant, since it has important therapeutic and prognostic implications. NSIP encloses different pathologies, namely those with inflammatory predominance (cellular subtype) or fibrous predominance (fibrosing subtype). NSIP is reviewed and discussed by the authors, after two clinical cases description.

To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison ofmore » emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease.« less

Sarcoidosis is a multisystemic disease of unknown etiology. Up to 30% of patients develop cutaneous manifestations, either specific or nonspecific. Ulcerating sarcoidosis leading to leg ulcers is a rare observation that may lead to confusions with other, more common types of chronic leg ulcers. We report the case of a 45-year-old female patient with chronic multisystemic sarcoidosis presenting with pretibial leg ulcers. Other etiology could be excluded. Histology revealed nonspecific findings. Therefore, the diagnosis of nonspecific leg ulcers in sarcoidosis was confirmed. Treatment consisted of oral prednisolone and good ulcer care. Complete healing was achieved within 6 months. Sarcoidosis is a rare cause of leg ulcers and usually sarcoid granulomas can be found. Our patient illustrates that even in the absence of sarcoid granulomas, leg ulcers can be due to sarcoidosis. © The Author(s) 2016.

Between 1.5 and 3.0/1000 people have active leg ulcers. Prevalence increases with age to about 20/1000 in people aged over 80 years. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of standard treatments, adjuvant treatments, and organisational interventions for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 80 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

This article describes the development of an educational electronic application (app) designed for use by patients at risk of pressure ulcers, and their carers. The app can be downloaded to Windows, Android or Apple smartphones or tablets. The app is based on the current pressure ulcer prevention and management guidelines from the National Pressure Ulcer Advisory Panel and the National Institute for Health and Care Excellence, and is designed to educate patients and carers about how to prevent a pressure ulcer, how to recognise a pressure ulcer, and what to do if they suspect they are developing a pressure ulcer. We hope the app will be used to help with educational conversations among patients, carers and healthcare professionals.

Pressure ulcer assessment and management.

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.

The discovery that Helicobacter pylori infection is the major cause of peptic ulcer disease revolutionised our views on the etiology and treatment of the disease. This discovery has tempted many experts to conclude that psychological factors and, specifically, stress are unimportant. However, Helicobacter pylori infection alone does not explain fully the incidence and prevalence of peptic ulcer disease. It has been demonstrated that stress can cause peptic ulcer disease even in the absence of Helicobacter pylori infection, supporting a multicausal model of peptic ulcer etiology. Psychological stress among other risk factors can function as a cofactor with Helicobacter pylori infection.

In recipients of hematopoietic stem cell transplants (HSCTs), BK virus (BKV) has been associated with late-onset hemorrhagic cystitis (HC). In our institution, HSCT recipients with BKV-associated HC are treated with 1 mg/kg of cidofovir weekly. We identified HSCT recipients with BKV-associated HC, treated with weekly cidofovir. Microbiological response was defined as at least a one log reduction in urinary BKV viral load; clinical response was defined as improvement in symptoms and stability or reduction in the grade of cystitis. Nineteen allogeneic HSCT patients received a mean of 4.5 weekly doses of cidofovir. HC occurred at a mean of 68.7 days after transplant. A clinical response was detected in 16/19 (84%) patients, and 9/19 (47%) had a measurable microbiological response (8/10 nonresponders had a BKV viral load above the upper limit of the assay before treatment). Fourteen out of nineteen (74%) patients had no significant increase in serum creatinine. Five patients with renal dysfunction resolved after completion of the therapy and removal of other nephrotoxic agents. We conclude that weekly low-dose cidofovir appears to be a safe treatment option for BKV-associated HC. Although the efficacy of low-dose cidofovir is not proven, a prospective trial is warranted.

Acetylene is a colorless gas commonly used for welding. It acts mainly as a simple asphyxiant. In this paper, however, we present a patient who developed a severe interstitial pneumonitis after acetylene exposure during aluminum welding. A 44-year old man was welding with acetylene, argon and aluminum electrode sticks in a non-ventilated aluminum tank for 2 h. Four hours after welding dyspnea appeared and 22 h later he was admitted at the Emergency Department due to severe respiratory insufficiency with pO2 = 6.7 kPa. Chest X-ray showed diffuse interstitial infiltration. Pulmonary function and gas diffusion tests revealed a severe restriction (55% of predictive volume) and impaired diffusion capacity (47% of predicted capacity). Toxic interstitial pneumonitis was diagnosed and high-dose systemic corticosteroid methylprednisolone and inhalatory corticosteroid fluticasone therapy was started. Computed Tomography (CT) of the lungs showed a diffuse patchy ground-glass opacity with no signs of small airway disease associated with interstitial pneumonitis. Corticosteroid therapy was continued for the next 8 weeks gradually reducing the doses. The patient's follow-up did not show any deterioration of respiratory function. In conclusion, acetylene welding might result in severe toxic interstitial pneumonitis that improves after an early systemic and inhalatory corticosteroid therapy.

Hospital-acquired pressure ulcer occurrences have declined over the past decade as reimbursement policies have changed, evidence-based practice guidelines have been implemented, and quality improvement initiatives have been launched. However, the 2006-2008 Institute for Healthcare Improvement goal of zero pressure ulcers remains difficult to achieve and even more challenging to sustain. Magnet hospitals tend to have lower hospital-acquired pressure ulcer rates than non-Magnet hospitals, yet many non-Magnet hospitals also have robust pressure ulcer prevention programs. Successful programs share commonalities in structure, processes, and outcomes. A national summit of 55 pressure ulcer experts was convened at the Virginia Commonwealth University Medical Center in March 2014. The group was divided into 3 focus groups; each was assigned a task to develop a framework describing components of a proposed Magnet-designated Center of Pressure Ulcer Prevention Excellence. Systematic literature reviews, analysis of exemplars, and nominal group process techniques were used to create the framework. This article presents a framework describing the proposed Magnet-designated Centers of Pressure Ulcer Prevention Excellence. Critical attributes of Centers of Excellence are identified and organized according to the 4 domains of the ANCC model for the Magnet Recognition Program: transformational leadership; structural empowerment; exemplary professional practice; and new knowledge innovation and improvements. The structures, processes, and outcome measures necessary to become a proposed Center of Pressure Ulcer Prevention Excellence are discussed.

This study aimed to determine the incidence of pressure ulcers in patients on mechanical ventilation and selected risk factors likely to play a role in pressure ulcer development. The study included 110 patients recruited from an anesthesia critical care unit of a university hospital. Data were collected with a demographic and clinical characteristics form. The form was composed of questions about demographic characteristics and clinical features including diagnosis, duration of mechanical ventilation, general well-being, oxygenation, perfusion, and skin condition. The incidence of pressure ulcer was 15.5%. Duration of mechanical ventilation was longer and the body mass index was higher in patients developing pressure ulcers than in those without pressure ulcers. Additionally, 90.11% of patients with pressure ulcers had edema and 82.35% of patients with pressure ulcers received vasopressin. The patients with pressure ulcers had higher PH levels, lower PaO2 levels, higher PCO2 levels, lower SaO2 levels, and higher urine output. It can be recommended that nurses and other health professionals should be aware of factors playing a role in pressure ulcer development and should be able to conduct appropriate interventions to prevent pressure ulcers.

Ca v 3.2 T-type Ca 2+ channel activity is suppressed by zinc that binds to the extracellular histidine-191 of Ca v 3.2, and enhanced by H 2 S that interacts with zinc. Ca v 3.2 in nociceptors is upregulated in an activity-dependent manner. The enhanced Ca v 3.2 activity by H 2 S formed by the upregulated cystathionine-γ-lyase (CSE) is involved in the cyclophosphamide (CPA)-induced cystitis-related bladder pain in mice. We thus asked if zinc deficiency affects the cystitis-related bladder pain in mice by altering Ca v 3.2 function and/or expression. Dietary zinc deficiency for 2 weeks greatly decreased zinc concentrations in the plasma but not bladder tissue, and enhanced the bladder pain/referred hyperalgesia (BP/RH) following CPA at 200mg/kg, a subeffective dose, but not 400mg/kg, a maximal dose, an effect abolished by pharmacological blockade or gene silencing of Ca v 3.2. Acute zinc deficiency caused by systemic N,N,N',N'-tetrakis-(2-pyridylmethyl)-ethylendiamine (TPEN), a zinc chelator, mimicked the dietary zinc deficiency-induced Ca v 3.2-dependent promotion of BP/RH following CPA at 200mg/kg. CPA at 400mg/kg alone or TPEN plus CPA at 200mg/kg caused Ca v 3.2 overexpression accompanied by upregulation of Egr-1 and USP5, known to promote transcriptional expression and reduce proteasomal degradation of Ca v 3.2, respectively, in the dorsal root ganglia (DRG). The CSE inhibitor, β-cyano-l-alanine, prevented the BP/RH and upregulation of Ca v 3.2, Egr-1 and USP5 in DRG following TPEN plus CPA at 200mg/kg. Together, zinc deficiency promotes bladder pain accompanying CPA-induced cystitis by enhancing function and expression of Ca v 3.2 in nociceptors, suggesting a novel therapeutic avenue for treatment of bladder pain, such as zinc supplementation.

Background: The risk factors for urinary tract infections (UTIs) from developed countries are not applicable to women from developing world. Objective: To analyze the behavioral practices and psychosocial aspects pertinent to women in our region and assess their association with acute first time or recurrent UTI. Materials and Methods: Sexually active premenopausal women with their first (145) and recurrent (77) cystitis with Escherichia coli as cases and women with no prior history of UTI as healthy controls (257) were enrolled at a tertiary care hospital in India, between June 2011 and February 2013. Questionnaire-based data was collected from each participant through a structured face-to-face interview. Results: Using univariate and multivariate regression models, independent risk factors for the first episode of cystitis when compared with healthy controls were (presented in odds ratios [ORs] with its 95% confidence interval [CI]): Anal sex (OR = 3.68, 95% CI = 1.59-8.52), time interval between last sexual intercourse and current episode of UTI was <5 days (OR = 2.27, 95% CI = 1.22-4.23), use of cloth during menstrual cycle (OR = 2.36, 95% CI = 1.31-4.26), >250 ml of tea consumption per day (OR = 4.73, 95% CI = 2.67-8.38), presence of vaginal infection (OR = 3.23, 95% CI = 1.85-5.62) and wiping back to front (OR = 2.52, 95% CI = 1.45-4.38). Along with the latter three, history of UTI in a first-degree female relative (OR = 10.88, 95% CI = 2.41-49.07), constipation (OR = 4.85, 95% CI = 1.97-11.92) and stress incontinence (OR = 2.45, 95% CI = 1.18-5.06) were additional independent risk factors for recurrent cystitis in comparison to healthy controls. Conclusion: Most of the risk factors for initial infection are potentially modifiable but sufficient to also pose risk for recurrence. Many of the findings reflect the cultural and ethnic practices in our country. PMID:26917870

The aim of this study was to calculate and analyze the cost of treatment for stage IV pressure ulcers. A retrospective chart analysis of patients with stage IV pressure ulcers was conducted. Hospital records and treatment outcomes of these patients were followed up for a maximum of 29 months and analyzed. Costs directly related to the treatment of pressure ulcers and their associated complications were calculated. Nineteen patients with stage IV pressure ulcers (11 hospital-acquired and 8 community-acquired) were identified and their charts were reviewed. The average hospital treatment cost associated with stage IV pressure ulcers and related complications was $129,248 for hospital-acquired ulcers during 1 admission, and $124,327 for community-acquired ulcers over an average of 4 admissions. The costs incurred from stage IV pressure ulcers are much greater than previously estimated. Halting the progression of early stage pressure ulcers has the potential to eradicate enormous pain and suffering, save thousands of lives, and reduce health care expenditures by millions of dollars.

Objectives To provide comprehensive trial methods and baseline data for the Steroids for Corneal Ulcers Trial and to present epidemiological characteristics such as risk factors, causative organisms, and ulcer severity. Methods Baseline data from a 1:1 randomized, placebo-controlled, double-masked clinical trial comparing prednisolone phosphate, 1%, with placebo as adjunctive therapy for the treatment of bacterial corneal ulcers. Eligible patients had a culture-positive bacterial corneal ulcer and had been taking moxifloxacin for 48 hours. The primary outcome for the trial is best spectacle-corrected visual acuity at 3 months from enrollment. This report provides comprehensive baseline data, including best spectacle-corrected visual acuity, infiltrate size, microbio-logical results, and patient demographics, for patients enrolled in the trial. Results Of 500 patients enrolled, 97% were in India. Two hundred twenty patients (44%) were agricultural workers. Median baseline visual acuity was 0.84 logMAR (Snellen, 20/125) (interquartile range, 0.36-1.7; Snellen, 20/50 to counting fingers). Baseline visual acuity was not significantly different between the United States and India. Ulcers in India had larger infiltrate/scar sizes (P=.04) and deeper infiltrates (P=.04) and were more likely to be localized centrally (P=.002) than ulcers enrolled in the United States. Gram-positive bacteria were the most common organisms isolated from the ulcers (n=366, 72%). Conclusions The Steroids for Corneal Ulcers Trial will compare the use of a topical corticosteroid with placebo as adjunctive therapy for bacterial corneal ulcers. Patients enrolled in this trial had diverse ulcer severity and on average significantly reduced visual acuity at presentation. PMID:21987581

Psychological factors in ulcerative colitis.

Almost 50 years ago ulcerative colitis was included among the seven classical psychosomatic diseases. The psychodynamics and personality structures specific to ulcerative colitis sufferers were sought and the main-stay of treatment was psychotherapy. However, for the past decade the psychogenic approach to this disorder has been replaced by physiological and immunological explanations and treatments. The history of medical and psychogenic explanations and treatments of ulcerative colitis has been traced to the present. Ulcerative colitis remains a "riddle," as it was described almost 50 years ago, a complex disorder whose pattern is to flare up and subside, its cause and cure still unknown despite almost 100 years of study.

A prospective microbiological study of 48 patients with corneal ulcers due to bacterial infection was performed. Positive cultures of corneal ulcer samples were obtained in 60% of all patients; about half of these patients had received antimicrobial treatment prior to sampling. A relatively high incidence of Staphylococcus epidermidis was isolated from ulcer patients (27%) compared with normal controls (10%). Gram stains of ulcer samples were positive for organisms in only 27% of all patients and were not considered useful in determining initial therapy in this series. We concluded that treatment should be started with a broad combination of antibiotics while awaiting the culture results. PMID:3082352

Fibrous and interstitial proteins compose the extracellular matrix of the vocal fold lamina propria and account for its biomechanic properties. Vocal fold scarring is characterized by altered biomechanical properties, which create dysphonia. Although alterations of the fibrous proteins have been confirmed in the rabbit vocal fold scar, interstitial proteins, which are known to be important in wound repair, have not been investigated to date. Using a rabbit model, interstitial proteins decorin, fibromodulin, and fibronectin were examined immunohistologically, two months postinduction of vocal fold scar by means of forcep biopsy. Significantly decreased decorin and fibromodulin with significantly increased fibronectin characterized scarred vocal fold tissue. The implications of altered interstitial proteins levels and their affect on the fibrous proteins will be discussed in relation to increased vocal fold stiffness and viscosity, which characterizes vocal fold scar.

Radiation damage not only seriously degrades the mechanical properties of tungsten (W) but also enhances hydrogen retention in the material. Introducing a large amount of defect sinks, e.g. grain boundaries (GBs) is an effective method for improving radiation-resistance of W. However, the mechanism by which the vacancies are dynamically annihilated at long timescale in nano-crystal W is still not clear. The dynamic picture for eliminating vacancies with single interstitials and small interstitial-clusters has been investigated by combining molecular dynamics, molecular statics and object Kinetic Monte Carlo methods. On one hand, the annihilation of bulk vacancies was enhanced due to the reflection of an interstitial-cluster of parallel ≤ft< 1 1 1 \\right> crowdions by the GB. The interstitial-cluster was observed to be reflected back into the grain interior when approaching a locally dense GB region. Near this region, the energy landscape for the interstitial was featured by a shoulder, different to the decreasing energy landscape of the interstitial near a locally loose region as indicative of the sink role of the GB. The bulk vacancy on the reflection path was annihilated. On the other hand, the dynamic interstitial emission efficiently anneals bulk vacancies. The single interstitial trapped at the GB firstly moved along the GB quickly and clustered to be the di-interstitial therein, reducing its mobility to a value comparable to that that for bulk vacancy diffusion. Then, the bulk vacancy was recombined via the coupled motion of the di-interstitial along the GB, the diffusion of the vacancy towards the GB and the accompanying interstitial emission. These results suggest that GBs play an efficient role in improving radiation-tolerance of nano-crystal W via reflecting highly-mobile interstitials and interstitial-clusters into the bulk and annihilating bulk vacancies, and via complex coupling of in-boundary interstitial diffusion, clustering of the interstitial

The study was aimed at comparatively assessing the efficacy of treatment for venous trophic ulcers at stages II-III of the wound process using special compression knee-length socks of the ULCER X kit (Sigvaris AG, St. Gallen, Switzerland) and long-stretch bandages Lauma. Compression therapy was included into the programme of outpatient treatment of forty 31-to-74-year-old patients presenting with trophic ulcers (stage II-III of the wound process) with an average area of 5,36±1,1 cm2. The Study Group consisting of 20 patients used compression knitted fabrics in the form of knee-length socks ULCER X and the comparison group (n=20) used long-stretch bandages Lauma. The obtained findings (6 months) demonstrated that using compression therapy exerted a positive effect on the process of healing of venous trophic ulcers, also proving advantages of compression therapy with the knee-length socks ULCER X that create an adequate level of pressure on the crus and maintain it in long-term daily use, reliably accelerating the healing of venous trophic ulcers as compared with elastic long-stretch bandages. The use of long-stretch elastic bandages in treatment of venous trophic ulcers turned out to be not only ineffective but fraught with a possibility of the development of various complications. During 6 months of follow up the patients using the special knee-length socks ULCER X were found to have 80 % of ulcers healed (16 patients), mainly within the first 2 months, whereas using elastic bandages resulted in only 30 % of healing (6 patients) by the end of the study. Along with it, we documented a considerable decrease in the malleolar circumference in the study group patients (from 30,05±0,78 to 28,35±0,86 cm) and in the control group from 31,2±30,35 to 30,25±0,75 cm), accompanied and followed by more than a two-fold increase in quality of life of the patients along all the parameters in the study group and a 1.4-fold increase in the control group patients.

Airway-centered interstitial fibrosis is a little known clinical entity that has only recently been described in the literature. Its pathology is characterized by bronchial fibrosis and localized interstitial pulmonary fibrosis around the airways. The disease has been associated with inhalation of a variety of substances, environmental or occupational, organic or inorganic. Clinical signs, radiographic manifestations, and lung function in patients with airway-centered interstitial fibrosis are similar to those of patients with idiopathic interstitial pneumonia. We describe a case of airway-centered interstitial fibrosis related to exposure to fumes from cleaning products.

The healing process of cysteamine-induced duodenal ulcer was studied by (/sup 3/H)thymidine autoradiography. After the development of ulcer in the duodenum, cell proliferation was markedly activated not only in the crypts but also in the Brunner's glands near the ulcer. In the initial stages of ulcer healing, they both contributed to form the surface covering regenerating epithelium. Granulation tissue also proliferated at the base of the ulcer. In later stages of ulcer healing, new crypts were formed in the floor of the ulcer. New villi regenerated from these crypts and Brunner's glands regenerated by proliferation in situ. The ulcer basemore » then was completely covered with new villi and granulation tissue was replaced by dense fibrous connective tissue.

Hyperbaric oxygen therapy (HBOT) is a medical technique which delivers oxygen at ambient pressures to increase the amount of dissolved oxygen in the blood and oxygen distribution to tissues. There are several beneficial properties of HBOT concomitant with elevated oxygen distribution in tissue including anti-inflammation, angiogenesis through vascular endothelial growth factor proliferation, augmented fibroblast activity through fibroblast growth factor proliferation, tissue and wound repair, enhancement of lymphocyte and macrophage activity, increased male testosterone secretion, and bactericidal activity. Given its renown in treating conditions such as decompression sickness and carbon monoxide poisoning, HBOT is making gradual strides for use in genitourinary medicine due to its low risk and likeliness to achieve favorable results. Early success has been observed in the treatment of Fournier's gangrene, radiation cystitis, and interstitial cystitis via the elimination of clinical symptoms such as pain. Further indications that have exhibited positive outcomes despite HBOT's ambiguous mechanism of action include cyclophosphamide hemorrhagic cystitis, emphysematous cystitis, pelvic radiation disease, radiation-induced proctopathy, dystrophic calcification of the prostate, erectile dysfunction secondary to urethroplasty, priapism, abnormal renal morphology, blood testosterone, calcific uremic arteriolopathy, and hidradenitis suppurativa. For other indications, multicenter studies must be conducted to determine HBOT's true efficacy, mechanism of action, risks, and advantages over conventional treatments.

Novel Treatment of Chronic Bladder Pain Syndrome and Other Pelvic Pain Disorders by OnabotulinumtoxinA Injection.

2015-06-18

Chronic pelvic pain (CPP) is defined as pain in the pelvic organs and related structures of at least 6 months' duration. The pathophysiology of CPP is uncertain, and its treatment presents challenges. Botulinum toxin A (BoNT-A), known for its antinociceptive, anti-inflammatory, and muscle relaxant activity, has been used recently to treat refractory CPP with promising results. In patients with interstitial cystitis/bladder pain syndrome, most studies suggest intravesical BoNT-A injection reduces bladder pain and increases bladder capacity. Repeated BoNT-A injection is also effective and reduces inflammation in the bladder. Intraprostatic BoNT-A injection could significantly improve prostate pain and urinary frequency in the patients with chronic prostatitis/chronic pelvic pain syndrome. Animal studies also suggest BoNT-A injection in the prostate decreases inflammation in the prostate. Patients with CPP due to pelvic muscle pain and spasm also benefit from localized BoNT-A injections. BoNT-A injection in the pelvic floor muscle improves dyspareunia and decreases pelvic floor pressure. Preliminary studies show intravesical BoNT-A injection is useful in inflammatory bladder diseases such as chemical cystitis, radiation cystitis, and ketamine related cystitis. Dysuria is the most common adverse effect after BoNT-A injection. Very few patients develop acute urinary retention after treatment.

The Alport syndrome is a hereditary glomerular disease linked to structural abnormalities of collagen IV. In a mouse model of Alport syndrome, the interstitial lymphocyte influx was important for disease progression. CXCR3 is a chemokine receptor involved in lymphocyte recruitment to the kidney. We hypothesized that CXCR3-positive T cells might be involved in human Alport syndrome. Immunohistochemistry was performed on formalin-fixed, paraffin-embedded biopsies from 17 patients with Alport syndrome, 10 with immunoglobulin A (IgA) nephropathy, and 11 healthy donor kidneys. We investigated the expression of the alpha5 chain of collagen IV to confirm the morphologic diagnosis, the chemokine receptor CXCR3 and CD3-positive T cells. Alport syndrome biopsies demonstrated a complete loss of the alpha5 chain of collagen IV from the glomerular basement membrane and the morphologic features consistent with Alport syndrome on electron microscopy. A prominent number of CXCR3-positive cells were found in the tubulointerstitium. Most of the CXCR3-positive cells were CD3-positive T cells, demonstrated by double-labeling in selected biopsies. The number of CXCR3-positive cells in kidneys with Alport syndrome correlated with serum creatinine (P < .05) and with morphologic features of a progressive disease (eg, interstitial fibrosis, glomerulosclerosis, and tubular atrophy). The severity of interstitial CXCR3-positive cell influx was similar in Alport syndrome as compared to immunoglobulin A nephropathy. The noninflammatory glomerular lesion of Alport syndrome is associated with prominent interstitial accumulation of CD3- and CXCR3-positive lymphocytes. The degree of infiltration correlated with renal function. We speculate that targeting T lymphocytes, for example, by CXCR3 blocking agents, might be a novel approach to inhibit disease progression in patients with Alport syndrome.

Critically ill patients are at high risk of developing pressure ulcers resulting in serious untoward patient and health care system outcomes. Pressure ulcer prevention is therefore an important patient safety priority and establishing a structured approach to pressure ulcer risk assessment to identify patients at risk is a critical first step. The literature was searched using three electronic databases from 2000 to 2011 to identify papers reporting on pressure ulcer risk factors and assessment in adult critical care. The review and appraisal of papers were conducted by two critical care nurses. Papers underwent detailed review if they met inclusion criteria where they identified pressure ulcer assessment scores, scales or risk factors and related to adult critical care patients Seven papers were reviewed. No single assessment tool was sufficiently validated for critically ill patients and seven key critical care risk factors were identified. These risk factors were: mechanical ventilation, impaired circulation, dialysis, long surgery, low protein and too unstable to turn. The tool Critical Care Pressure Ulcer Assessment Tool made Easy (CALCULATE) was developed utilizing the risk factors from the literature and expert critical care nursing consensus decision-making. In the absence of current consensus, valid assessment scales and limited evidence for the most appropriate pressure ulcer assessment for critically ill patients, this assessment tool offers an easy, appropriate alternative for critically ill patients than existing tools primarily validated for acute care wards. 'CALCULATE' offers an important contribution towards the advancement and development of critical care pressure ulcer risk assessment. Future research is needed to further enhance and inform pressure ulcer risk assessment of the critically ill patients. The identification of critical care risk factors may be an indicative method of assessing pressure ulcer risk in the critically ill patients. �

Since 1997, we, the community pharmacists, have established this society, Aichi Prefecture Society for the Study of Pressure Ulcers Care, in order to furnish drug information about pressure ulcers care. Moist atmosphere is required for the healing of pressure ulcers. The moist environment that could be regulated depends on the physicochemical property of ointment bases. Therefore, ointment should reasonably be chosen to adjust the moisture. Since 2000, we have been committed to providing pharmacists, who work on home care, with a booklet to instruct how to choose ointments for pressure ulcers treatment. In 2002, when the Aichi pharmaceutical association held a training conference held at various hospitals using the booklet as a teaching material, hospital pharmacists cooperated by making a field study trip to observe pressure ulcers treatments. Nowadays researchers at pharmaceutical colleges have also cooperated in studying the efficacy and economical effect of the method of blending different ointments to improve the healing process of pressure ulcers.

Although prevalence of peptic ulcer is decreasing, the number of peptic ulcer perforations appears to be unchanged. This complication of peptic ulcer is traditionally surgically treated. In recent years, a number of papers have been published where the authors managed perforated duodenal peptic ulcer in selected patients using laparoscopic approach. Laparoscopic treatment of perforated duodenal ulcer has been described as safe and advantageous compared to open technique but advantages are still not clear due to small number of cases in published studies. Based on these recommendations we decided to establish our own protocol for laparoscopic treatment of perforated peptic duodenal ulcer. In this prospective study we evaluated the first 10 patients in whom we performed laparoscopic repair of perforated duodenal ulcer. There were no conversions to open procedure and no early postoperative complications. The patients were contacted by phone a year after the operation, and all were satisfied with the operation and the appearance of postoperative scars. We regard laparoscopic repair of selected patients with perforated duodenal ulcer as a safe and preferable treatment.

The treatment of a bleeding chronic posterior duodenal ulcer, with bleeding recurrence or persistence despite endoscopic therapy, requires surgical treatment and constitutes a challenge for the surgeon; furthermore such chronic ulcers are often wide and sclerotic, so the surgeon needs to avoid the risk of recurrent bleeding if conservative surgery is applied. If radical surgery must be performed, the greater risk involves duodenal leakage, hepatic hilar injury, or pancreatic injury. This study aimed to evaluate the efficacy and complications arising from a surgical procedure, described by Dubois in 1971 (Gastrectomy and gastroduodenal anastomosis for post-bulbar ulcers and peptic ulcers of the second part of the duodenum. J Chir 101:177-186). This operation involves antroduonectomy with gastroduodenal anastomosis. It is similar to a Billroth I gastrectomy but without dissection of the ulcer. We retrospectively studied the medical data of patients who underwent this procedure for the treatment of bleeding chronic posterior duodenal ulcers during the past 20 years. There were 28 such patients admitted to our institution for emergency surgery, who went on to be treated by the Dubois procedure. Ulcerous disease was efficiently treated without rebleeding or duodenal leakage. The mortality rate was 17%; most deaths resulted from medical failure in older patients suffering from massive bleeding. The rate of medical complications reached 21%. Surgical complications developed in 14% of patients. The Dubois antroduodenectomy is a safe and effective surgical procedure for the treatment of bleeding chronic duodenal ulcers. The number of fatal outcomes among patients with this condition remains high, particularly in older and vulnerable patients experiencing massive bleeding.

The incidence of peptic ulcer has steadily declined through out the world. This decreasing trend is also noticeable in this subcontinent. The point prevalence of peptic ulcer (PUD) in Bangladesh was around 15% in eighties. The aim of this study was to see the present prevalence of peptic ulcer at endoscopy and to identify changing trends in the occurrence of peptic ulcer in Bangladesh. This retrospective analysis of the endoscopic records of multiple tertiary referral centres of Dhaka city were done from January 2012 to July 2013. A total of 5608 subjects were the study samples. We included those patients having peptic ulcer in the form of duodenal ulcer, benign gastric ulcer including pre-pyloric ulcer and gastric outlet obstruction due to peptic ulcer. Duodenal ulcer and benign gastric ulcer were found in 415(7.4%) and 184(3.28%) patients respectively and gastric outlet obstruction due to peptic ulcer was found in 23(0.40%) patients.

Antacids and peptic ulcer--a reappraisal.

Antacids can reduce gastroduodenal acidity for long periods if taken in substantial quantities after food. Their healing effect on gastric ulcer is minimal, if present at all, and easily overwhelmed by the benefit obtained from admission to hospital. Intensive antacid therapy appears effective in healing duodenal ulcer and preventing haemorrhage from stress ulcer, and is comparable in these respects with cimetidine but with a higher incidence of side-effects. Clinical impression strongly suggests that antacids relieve pain in peptic ulcer but objective confirmation is lacking. PMID:38192

Fotemustine is an alkylating cytostatic drug belonging to the nitrosourea family and is used in particular in the treatment of disseminated malignant melanoma. Herein, we report a case of interstitial lung disease associated with fotemustine. An 81-year-old man treated with fotemustine for metastatic melanoma presented acute interstitial lung disease 20 days after a fourth course of fotemustine monotherapy. The condition regressed spontaneously, with the patient returning to the clinical, radiological and blood gas status that had preceded fotemustine treatment. After other potential aetiologies had been ruled out, acute fotemustine-induced lung toxicity was considered and this treatment was definitively withdrawn. Other cytostatic agents belonging to the nitrosourea family can cause similar pictures, with a number of cases of interstitial lung disease thus being ascribed to fotemustine and dacarbazine. To our knowledge, this is the first case of interstitial lung disease induced by fotemustine monotherapy. This diagnosis should be considered where respiratory signs appear in melanoma patients undergoing fotemustine treatment. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Support surfaces for pressure ulcer prevention.

Pressure ulcers (i.e. bedsores, pressure sores, pressure injuries, decubitus ulcers) are areas of localised damage to the skin and underlying tissue. They are common in the elderly and immobile, and costly in financial and human terms. Pressure-relieving support surfaces (i.e. beds, mattresses, seat cushions etc) are used to help prevent ulcer development. This systematic review seeks to establish:(1) the extent to which pressure-relieving support surfaces reduce the incidence of pressure ulcers compared with standard support surfaces, and,(2) their comparative effectiveness in ulcer prevention. In April 2015, for this fourth update we searched The Cochrane Wounds Group Specialised Register (searched 15 April 2015) which includes the results of regular searches of MEDLINE, EMBASE and CINAHL and The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2015, Issue 3). Randomised controlled trials (RCTs) and quasi-randomised trials, published or unpublished, that assessed the effects of any support surface for prevention of pressure ulcers, in any patient group or setting which measured pressure ulcer incidence. Trials reporting only proxy outcomes (e.g. interface pressure) were excluded. Two review authors independently selected trials. Data were extracted by one review author and checked by another. Where appropriate, estimates from similar trials were pooled for meta-analysis. For this fourth update six new trials were included, bringing the total of included trials to 59.Foam alternatives to standard hospital foam mattresses reduce the incidence of pressure ulcers in people at risk (RR 0.40 95% CI 0.21 to 0.74). The relative merits of alternating- and constant low-pressure devices are unclear. One high-quality trial suggested that alternating-pressure mattresses may be more cost effective than alternating-pressure overlays in a UK context.Pressure-relieving overlays on the operating table reduce postoperative pressure ulcer incidence

Objective: Gastric ulcer is an important clinical problem, chiefly due to extensive use of some drugs. The aim was to assess the activity of Mumijo extract (which is used in traditional medicine) against acetic acid induced gastric ulcer in rats. Materials and Methods: The aqueous extract of Mumijo was prepared. Animals were randomly (n = 10) divided into four groups: Control, sham-operated group (received 0.2 ml of acetic acid to induce gastric ulcer), Mumijo (100 mg/kg/daily) were given for 4 days postacetic acid administration, and ranitidine group (20 mg/kg). The assessed parameters were pH and pepsin levels (by Anson method) of gastric contents and gastric histopathology. Ranitidine was used as reference anti-ulcer drug. Results: The extract (100 mg/kg/daily, p.o.) inhibited acid acetic-induced gastric ulceration by elevating its pH versus sham group (P < 0.01) and decreasing the pepsin levels compared to standard drug, ranitidine (P < 0.05). The histopathology data showed that the treatment with Mumijo extract had a significant protection against all mucosal damages. Conclusion: Mumijo extract has potent antiulcer activity. Its anti-ulcer property probably acts via a reduction in gastric acid secretion and pepsin levels. The obtained results support the use of this herbal material in folk medicine. PMID:25709338

Pressure ulcers: Back to the basics

Pressure ulcer in an otherwise sick patient is a matter of concern for the care givers as well as the medical personnel. A lot has been done to understand the disease process. So much so that USA and European countries have established advisory panels in their respective continents. Since the establishment of these organizations, the understanding of the pressure ulcer has improved significantly. The authors feel that the well documented and well publicized definition of pressure ulcer is somewhat lacking in the correct description of the disease process. Hence, a modified definition has been presented. This disease is here to stay. In the process of managing these ulcers the basic pathology needs to be understood well. Pressure ischemia is the main reason behind the occurrence of ulceration. Different extrinsic and intrinsic factors have been described in detail with review of literature. There are a large number of risk factors causing ulceration. The risk assessment scales have eluded the surgical literature and mostly remained in nursing books and websites. These scales have been reproduced for completion of the basics on decubitus ulcer. The classification of the pressure sores has been given in a comparative form to elucidate that most of the classifications are the same except for minor variations. The management of these ulcers is ever evolving but the age old saying of “prevention is better than cure” suits this condition the most. PMID:23162223

2007-01-01

The occurrence of giant urticaria and ulcerative colitis is very infrequent. A 23 year-old female reported the initial eruption of short-lived cutaneous itchy weals on her arms. Then lesions ran together and became confluent, extending to her legs, followed by undefined abdominal pain and a slight increase of body temperature. Exams showed hystologically confirmed ulcerative colitis, with perinuclear anti-neutrophil cytoplasmic antibody positivity. Ulcerative colitis therapy led not only to the remission of the colitic symptoms, but also to the prompt recovery of skin manifestations. Urticaria was the epiphenomenon of ulcerative colitis.

Objective: TNF-α is an inflammatory cytokine that plays a central role in promoting the cascade of events leading to an inflammatory response. Recent studies have suggested that TNF-α may play a key role in the formation and rupture of cerebral aneurysms, and that the underlying cerebral inflammatory response is a major determinate of outcome following subrarachnoid hemorrhage (SAH). Methods: We studied 14 comatose SAH patients who underwent multimodality neuromonitoring with intracranial pressure (ICP) and cerebral microdialysis as part of their clinical care. Continuous physiological variables were time-locked every 8 hours and recorded at the same point that brain interstitial fluid TNF-α was measured in brain microdialysis samples. Significant associations were determined using generalized estimation equations. Results: Each patient had a mean of 9 brain tissue TNF-α measurements obtained over an average of 72 hours of monitoring. TNF-α levels rose progressively over time. Predictors of elevated brain interstitial TNF-α included higher brain interstitial fluid glucose levels (β=0.066, P<0.02), intraventricular hemorrhage (β=0.085, P<0.021), and aneurysm size >6 mm (β=0.14, p<0.001). There was no relationship between TNF-α levels and the burden of cisternal SAH; concurrent measurements of serum glucose, or lactate-pyruvate ratio. Interpretation: Brain interstitial TNF-α levels are elevated after SAH, and are associated with large aneurysm size, the burden of intraventricular blood, and elevation brain interstitial glucose levels.

Gastric ulcer and the anti-arthritic drugs

PubMed Central

Sixteen cases are described of gastric ulcer in patients receiving anti-arthritic drugs. Half of the ulcers were in the antrum or on the greater curve. Ten patients were under treatment with indomethacin and/or prednisone, seven of them receiving both drugs. The ulcers healed readily when the drugs were withdrawn, and in the case of prednisone a continued daily dose of 10 mg or less did not prevent healing. All the patients with haemorrhage were taking aspirin, with or without other drugs. The literature is reviewed, and it is suggested that the increased incidence of peptic ulcer in patients receiving anti-arthritic drugs is confined to gastric ulcer. There is suggestive evidence of an increased susceptibility to antral ulcer in severe rheumatoid disease, which may largely account for the ‘steroid ulcer’. Indomethacin is potentially ulcerogenic, and its combined use with steroids may be inadvisable. Apart from its tendency to produce haemorrhagic erosions, the role of aspirin in the aetiology of chronic ulcer remains doubtful. No serious ill-effects have been reported in the use of ibuprofen or Distalgesic in ulcer subjects. PMID:5576491

Some immunological factors are responsible in the pathogenesis of ulcerative colitis. There is a relationship between cytokines and ulcerative colitis. In this study 20 ulcerative colitis patients (mean age 36.2 years old, 9 women, 11 men) and 20 healthy control groups (mean age 27.2 years old, 11 women, 9 men) were involved in the study. We established that IL-2Rsp, IL-6, IL-8 and IL-10 levels were different at the patients and control groups (p < 0.005). TNF-alpha and IL-1 beta were similar at the both groups. According to these results, IL-2Rsp, IL-6, 11-8 and IL-10 play an important role in the pathogenesis of ulcerative colitis. We consider that these cytokines are beneficial parameters in the diagnosis, treatment and prognosis of ulcerative colitis.

Parsons, C.L.; Anwar, H.; Stauffer, C.

Numerous investigators report data obtained using an in vitro quantitative assay for measuring bacterial adherence to epithelial cells. In the modified assay described here, we eliminated the need for visual counting of bacteria by incorporating the use of radioactively labeled Escherichia coli. This allowed quantitation of bacterial adherence to as many as 50,000 vaginal cells, whereas the visual counting system limits the determination to perhaps 50 cells. Using the modified method, we found no statistically significant differences among values for adherence of E. coli type 04 to the vaginal cells of control and cystitis-prone women at either pH 6.4 ormore » 4.0.« less

2015-07-15

This article reports on the introduction of an innovative computer-based system developed to record and report pressure ulcer risk and incidence at an acute NHS trust. The system was introduced to ensure that all patients have an early pressure ulcer risk assessment, which prompts staff to initiate appropriate management if a pressure ulcer is detected, thereby preventing further patient harm. Initial findings suggest that this electronic process has helped to improve the timeliness and accuracy of data on pressure ulcer risk and incidence. In addition, it has resulted in a reduced number of reported hospital-acquired pressure ulcers.

Edemagenic gain and interstitial fluid volume regulation.

PubMed

Dongaonkar, R M; Quick, C M; Stewart, R H; Drake, R E; Cox, C S; Laine, G A

2008-02-01

Under physiological conditions, interstitial fluid volume is tightly regulated by balancing microvascular filtration and lymphatic return to the central venous circulation. Even though microvascular filtration and lymphatic return are governed by conservation of mass, their interaction can result in exceedingly complex behavior. Without making simplifying assumptions, investigators must solve the fluid balance equations numerically, which limits the generality of the results. We thus made critical simplifying assumptions to develop a simple solution to the standard fluid balance equations that is expressed as an algebraic formula. Using a classical approach to describe systems with negative feedback, we formulated our solution as a "gain" relating the change in interstitial fluid volume to a change in effective microvascular driving pressure. The resulting "edemagenic gain" is a function of microvascular filtration coefficient (K(f)), effective lymphatic resistance (R(L)), and interstitial compliance (C). This formulation suggests two types of gain: "multivariate" dependent on C, R(L), and K(f), and "compliance-dominated" approximately equal to C. The latter forms a basis of a novel method to estimate C without measuring interstitial fluid pressure. Data from ovine experiments illustrate how edemagenic gain is altered with pulmonary edema induced by venous hypertension, histamine, and endotoxin. Reformulation of the classical equations governing fluid balance in terms of edemagenic gain thus yields new insight into the factors affecting an organ's susceptibility to edema.

Background: Historically, complication rates after pressure ulcer reconstruction utilizing flap coverage have been high. Patients undergoing operations for pressure ulcer coverage typically have multiple risk factors for postoperative complications. The purpose of this study was to examine a large patient series in the pressure ulcer population to uncover objective evidence of the linkage between risk factors and outcomes after flap coverage. Methods: This study was a retrospective chart review of patients who underwent flap reconstruction for a pressure ulcer between 1997 and 2015. The characteristics of patients were analyzed to determine those who had complications such as pressure ulcer recurrence, wound dehiscence, and wound infection. Results: All patients (N = 276) underwent flap coverage of their pressure ulcers. The overall complication rate was 58.7% (162 patients). Wound dehiscence was the most common complication (31.2%), and the pressure ulcer recurrence rate was 28.6%. Multivariate regression for pressure ulcer recurrence revealed that body mass index <18.5 [relative risk (RR) 3.13], active smoking (RR 2.33), and ischial pressure ulcers (RR 3.46) were independent risk factors for pressure ulcer recurrence. Ischial pressure ulcers (RR 2.27) and preoperative osteomyelitis (RR 2.78) were independent risk factors for wound dehiscence. Diabetes was an independent risk factor for wound infection (RR 4.34). Conclusions: Our retrospective analysis revealed numerous factors that are associated with high rates of major postoperative complications. Risk factors must be taken into account when offering flap coverage, and risk-reducing strategies must be implemented in patients before pressure ulcer reconstruction. PMID:28203494

Therapeutics for Equine Gastric Ulcer Syndrome.

PubMed

Zavoshti, Fereydon Rezazadeh; Andrews, Frank M

2017-04-01

Equine gastric ulcer syndrome (EGUS) is an umbrella term used to describe ulcers in the nonglandular squamous and glandular mucosa, terminal esophagus, and proximal duodenum. Gastric ulcers in the squamous and glandular regions occur more often than esophageal or duodenal ulcers and likely have a different pathogenesis. At present, omeprazole is accepted globally as the best pharmacologic therapy for both regions of the stomach; however, the addition of coating agents and synthetic prostaglandins could add to its effectiveness in treatment of EGUS. Dietary and environmental management are necessary for prevention of recurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

Hospital acquired pressure ulcers (HAPU) are serious, debilitating, and preventable complications in all inpatient populations. Despite evidence of the development of pressure ulcers in the pediatric population, minimal research has been done. Based on observations gathered during quarterly HAPU audits, bedside nursing staff recognized trends in pressure ulcer locations that were not captured using current pressure ulcer risk assessment tools. Together, bedside nurses and nursing leadership created and conducted multiple research studies to investigate the validity and reliability of the Pediatric Pressure Ulcer Prediction and Evaluation Tool (PPUPET).

The Yersiniabactin-Associated ATP Binding Cassette Proteins YbtP and YbtQ Enhance Escherichia coli Fitness during High-Titer Cystitis

PubMed Central

Koh, Eun-Ik; Hung, Chia S.

2016-01-01

The Yersinia high-pathogenicity island (HPI) is common to multiple virulence strategies used by Escherichia coli strains associated with urinary tract infection (UTI). Among the genes in this island are ybtP and ybtQ, encoding distinctive ATP binding cassette (ABC) proteins associated with iron(III)-yersiniabactin import in Yersinia pestis. In this study, we compared the impact of ybtPQ on a model E. coli cystitis strain during in vitro culture and experimental murine infections. A ybtPQ-null mutant exhibited no growth defect under standard culture conditions, consistent with nonessentiality in this background. A growth defect phenotype was observed and genetically complemented in vitro during iron(III)-yersiniabactin-dependent growth. Following inoculation into the bladders of C3H/HEN and C3H/HeOuJ mice, this strain exhibited a profound, 106-fold competitive infection defect in the subgroup of mice that progressed to high-titer bladder infections. These results identify a virulence role for YbtPQ in the highly inflammatory microenvironment characteristic of high-titer cystitis. The profound competitive defect may relate to the apparent selection of Yersinia HPI-positive E. coli in uncomplicated clinical UTIs. PMID:26883590

The lymphatic system is a highly complex biological system that facilitates the drainage of excess fluid in body tissues. In addition, it is an integral part of the immunological control system. Understanding the mechanisms of fluid absorption from the interstitial space and flow through the initial lymphatics is important to treat several pathological conditions. The main focus of this study is to computationally model the lymphatic drainage from the interstitial space. The model has been developed to consider a 3D lymphatic network and uses biological data to inform the creation of realistic geometries for the lymphatic capillary networks. We approximate the interstitial space as a porous region and the lymphatic vessel walls as permeable surfaces. The dynamics of the flow is approximated by Darcy's law in the interstitium and the Navier-Stokes equations in the lymphatic capillary lumen. The proposed model examines lymph drainage as a function of pressure gradient. In addition, we have examined the effects of interstitial and lymphatic wall permeabilities on the lymph drainage and the solute transportation in the model. The computational results are in accordance with the available experimental measurements.

Corneal ulceration following measles in Nigerian children.

PubMed Central

Sandford-Smith, J H; Whittle, H C

1979-01-01

Acute corneal ulceration in malnourished children is the commonest cause of childhood blindness in Northern Nigeria and usually develops after measles. Other severe diseases in malnourished children rarely precipitate corneal ulceration. A survey in a school for blind children showed that 69% of the children were blind from corneal disease, and a survey of children with corneal scars showed that at least 42% were caused by ulceration after measles. The clinical appearance of the active ulcers was very varied. The serum retinol-binding protein and prealbumin levels in children with corneal ulcers following measles were below normal, but a group of malnourished children without eye complaints following measles were found to have even lower levels. Thus a specific deficiency of vitamin A does not appear to be the primary cause of these ulcers, though it may be a contributory one. A specific measles keratitis and secondary herpes simplex infectious may be local factors contributing to this ulceration, and there is nearly always a background of protein calorie malnutrition. Racial factors may also be of some significance. PMID:508686

Mortality rates in complicated peptic ulcer disease are high. This study aimed to examine the prognostic importance of ulcer site in patients with peptic ulcer bleeding (PUB) and perforated peptic ulcer (PPU). a nationwide cohort study with prospective and consecutive data collection. all patients treated for PUB and PPU at Danish hospitals between 2003 and 2014. demographic and clinical data reported to the Danish Clinical Registry of Emergency Surgery. 90- and 30-d mortality and re-intervention. the crude and adjusted association between ulcer site (gastric and duodenal) and the outcome measures of interest were assessed by binary logistic regression analysis. Some 20,059 patients with PUB and 4273 patients with PPU were included; 90-d mortality was 15.3% for PUB and 29.8% for PPU; 30-d mortality was 10.2% and 24.7%, respectively. Duodenal bleeding ulcer, as compared to gastric ulcer (GU), was associated with a significantly increased risk of all-cause mortality within 90 and 30 d, and with re-intervention: adjusted odds ratio (OR) 1.47 (95% confidence interval 1.30-1.67); p < 0.001, OR 1.60 (1.43-1.77); p < 0.001, and OR 1.86 (1.68-2.06); p < 0.001, respectively. There was no difference in outcomes between gastric and duodenal ulcers (DUs) in PPU patients: adjusted OR 0.99 (0.84-1.16); p = 0.698, OR 0.93 (0.78 to 1.10); p = 0.409, and OR 0.97 (0.80-1.19); p = 0.799, respectively. DU site is a significant predictor of death and re-intervention in patients with PUB, as compared to GU site. This does not seem to be the case for patients with PPU.

Brandt, B.B.; Harney, J.

Interstitial thermoradiotherapy, an experimental cancer treatment that combines interstitial radiation implants (brachytherapy) and interstitial hyperthermia, is in the early stages of investigation. In accordance with the procedure used in a current national trial protocol, a 60-minute hyperthermia treatment is administered after catheters are placed into the tumor area while the patient is under general anesthesia. This is immediately followed by loading of radioactive Iridium-192 seeds into the catheters for a defined period of time. Once the prescribed radiation dose is delivered, the radioactive sources are removed and a second, 60-minute hyperthermia treatment is administered. Clinical trials with hyperthermia in combinationmore » with radiation have increased in recent years. Nurses caring for these patients need to become more knowledgeable about this investigational therapy. This paper provides an overview of the biologic rationale for this therapy, as well as a description of the delivery method and clinical application. Specific related nursing interventions are defined in a nursing protocol.23 references.« less

To evaluate the role of activity in the development of neuropathic foot ulceration in individuals with diabetes. We evaluated the first 100 consecutive individuals with diabetes (95.0% male, aged 68.5 +/- 10.0 years with concomitant neuropathy, deformity, and/or a history of lower-extremity ulceration/partial foot amputation) enrolled in an ongoing prospective longitudinal activity study. Subjects used a high-capacity continuous computerized activity monitor. Data were collected continuously over a minimum of 25 weeks (or until ulceration) with daily activity units expressed as means +/- SD. Eight subjects ulcerated during the evaluation period of 37.1 +/- 12.3 weeks. The average daily activity was significantly lower in individuals who ulcerated compared with individuals who did not ulcerate (809.0 +/- 612.2 vs. 1,394.5 +/- 868.5, P = 0.03). Furthermore, there was a large difference in variability between groups. The coefficient of variation was significantly greater in the ulceration group compared with the no ulceration group (96.4 +/- 50.3 vs. 44.7 +/- 15.4%, P = 0.0001). In the 2 weeks preceding the ulcerative event, the coefficient of variation increased even further (115.4 +/- 43.0%, P = 0.02), but there was no significant difference in average daily activity during that period (P = 0.5). The results of this study suggest that individuals with diabetes who develop ulceration may actually have a lower overall activity than their counterparts with no ulceration, but the quality of that activity may be more variable. Perhaps modulating the "peaks and valleys" of activity in this population through some form of feedback might prove to reduce risk for ulceration in this very-high-risk population.

The connection between Helicobacter pylori and complicated peptic ulcer disease in peptic ulcer bleeding (PUB) patients taking nonsteroidal anti-inflammatory drugs has not been established. In this study, we sought to determine whether delayed H. pylori eradication therapy in PUB patients increases complicated recurrent peptic ulcers. We identified inpatient PUB patients using the Taiwan National Health Insurance Research Database. We categorized patients into early (time lag ≤120 days after peptic ulcer diagnosis) and late H. pylori eradication therapy groups. The Cox proportional hazards model was used. The primary outcome was rehospitalization for patients with complicated recurrent peptic ulcers. Our data indicated that the late H. pylori eradication therapy group had a higher rate of complicated recurrent peptic ulcers (hazard ratio [HR], 1.52; p=0.006), with time lags of more than 120 days. However, our results indicated a similar risk of complicated recurrent peptic ulcers (HR, 1.20; p=0.275) in time lags of more than 1 year and (HR, 1.10; p=0.621) more than 2 years. H. pylori eradication within 120 days was associated with decreased complicated recurrent peptic ulcers in patients with PUB. We recommend that H. pylori eradication should be conducted within 120 days in patients with PUB.

The pre-ulcerative phase of carrageenan-induced colonic ulceration was investigated in guinea-pigs supplied 3% degraded carrageenan as an aqueous solution as drinking fluid for 2 or 3 days during which no ulceration of the bowel was observed with the naked eye or dissecting microscope. Mucosal microscopic changes, from caecum to rectum, were multifocal and included cellular infiltrates, dilatation of glands, crypt abscesses, micro-ulcers and sulphated polysaccharide in the lamina propria. Sulphated polysaccharide was also demonstrated histologically for the first time within the surface epithelium and showed ultrastructural features similar to carrageenan. The results indicate that colonic epithelium in the guinea-pig is capable of macromolecular absorption. Carrageenan, a highly active polyanionic electrolyte, within the surface epithelial cells is most likely a primary factor in the breakdown of mucosal integrity. Macromolecular absorption causing enteropathy of the large bowel is a new pathophysiological concept which may have implications in man, particularly in the pathology of large bowel disease.

Medical management of venous ulcers.

Venous disease is the most common cause of chronic leg ulceration and represents an advanced clinical manifestation of venous insufficiency. Due to their frequency and chronicity, venous ulcers have a high socioeconomic impact, with treatment costs accounting for 1% of the health care budget in Western countries. The evaluation of patients with venous ulcers should include a thorough medical history for prior deep venous thrombosis, assessment for an hypercoagulable state, and a physical examination. Use of the CEAP (clinical, etiology, anatomy, pathophysiology) Classification System and the revised Venous Clinical Severity Scoring System is strongly recommended to characterize disease severity and assess response to treatment. This venous condition requires lifestyle modification, with affected individuals performing daily intervals of leg elevation to control edema; use of elastic compression garments; and moderate physical activity, such as walking wearing below-knee elastic stockings. Meticulous skin care, treatment of dermatitis, and prompt treatment of cellulitis are important aspects of medical management. The pharmacology of chronic venous insufficiency and venous ulcers include essentially two medications: pentoxifylline and phlebotropic agents. The micronized purified flavonoid fraction is an effective adjunct to compression therapy in patients with large, chronic ulceration. Copyright © 2015 Elsevier Inc. All rights reserved.

BK polyomavirus-associated hemorrhagic cystitis (BK-PyVHC) is a significant complication of allogenic hematopoietic stem cell transplantation (HSCT), but risk factors and treatment are currently unresolved. BK-PyVHC typically presents with clinical cystitis, macrohematuria, and increasing urine and blood BKV loads. Characterization of children undergoing allogeneic HSCT with BK-PyVHC and their clinical and antibody response to cidofovir treatment. By prospective screening of urine and plasma in 50 pediatric allogenic HSCT performed between 2008 and 2010, we identified 6 (12%) children with BK-PyVHC. Cidofovir was administered intravenously to 5 patients and intravesically to 4 patients (3 double treatments). Decreasing BKV viremia of>2log(10)copies/mL and clinical resolution was seen in 4 patients over 5-12 weeks. Responses occurred only in patients mounting BKV-specific IgM and IgG responses. Epidemic curve plots, BKV genotyping and contact tracing provided evidence of transmission between 2 BKV-seronegative patients, but ruled out transmission among the remaining four patients The data suggest that BK-PyVHC may be the result of nosocomial transmission in children with low/undetectable BKV antibodies and raises urgent questions about appropriate infection control measures and the role of cidofovir.

Pressure ulcers are common in clinical practice and pose a significant health problem worldwide. Apart from causing suffering to patients, they also result in longer hospital stays and increase the cost of health care. A variety of methods are used for treating pressure ulcers, including pressure relief, patient repositioning, biophysical strategies, nutritional supplementation, debridement, topical negative pressure, and local treatments including dressings, ointments and creams such as bacitracin, silver sulphadiazine, neomycin, and phenytoin. Phenytoin is a drug more commonly used in the treatment of epilepsy, but may play an important role in accelerating ulcer healing. To assess the effects of topical phenytoin on the rate of healing of pressure ulcers of any grade, in any care setting. In September 2016, we searched the following electronic databases to identify relevant randomized clinical trials: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library); Ovid MEDLINE; Ovid Embase; and EBSCO CINAHL Plus. We handsearched conference proceedings from the European Pressure Ulcer Advisory Panel, European Wound Management Association and the Tissue Viability Society for all available years. We searched the references of the retrieved trials to identify further relevant trials. We also searched clinical trials registries to identify ongoing and unpublished studies. There were no restrictions with respect to language, date of publication or study setting. We included all randomized controlled trials (RCTs) addressing the effects (both benefits and harms) of topical phenytoin on the healing of pressure ulcers of any grade compared with placebo or alternative treatments or no therapy, irrespective of blinding, language, and publication status. Two review authors independently selected studies, extracted information on participants, interventions, methods and results and assessed risk of bias using

Pathophysiology diabetic foot ulcer

Diabetes Mellitus (DM) is known to have many complications. Diabetes and its complications are rapidly becoming the world’s most significant cause of morbidity and mortality, and one of the most distressing is Diabetic Foot Ulcer (DFU). Chronic wound complications are a growing concern worldwide, and the effect is a warning to public health and the economy. The etiology of a DFU is multifaceted, and several components cause added together create a sufficient impact on ulceration: neuropathy, vasculopathy, immunopathy, mechanical stress, and neuroarthropathy. There are many classifications of the diabetic foot. About 50% of patients with foot ulcers due to DM present clinical signs of infection. It is essential to manage multifactorial etiology of DFU to get a good outcome.

Ulcer disease of trout

USGS Publications Warehouse

Fish, F.F.

1934-01-01

During the summer of 1933, lesions of a disease were noted among some fingerling brook, rainbow, blackspotted, and lake trout at the Cortland (New York) trout hatchery. Although these lesions bore a marked superficial resemblance to those of furunculosis, they were sufficiently atypical to warrant further investigation. A more detailed examination of the lesions proved them to be of a distinct disease, which for lack of a better name is herein called "ulcer disease," for the lesions closely resemble those described by Calkins (1899) under this name. Because of the marked resemblance to furunculosis, ulcer disease has not been generally recognized by trout culturists, and any ulcer appearing on fish has been ascribed by them to furunculosis without further question.

Introduction Renal interstitial fibrosis (RIF) is a significant cause of end-stage renal failure. The goal of this study was to characterize the distribution of transplanted induced autologous stem cells in a rabbit model of renal interstitial fibrosis and evaluate its therapeutic efficacy for treatment of renal interstitial fibrosis. Methods A rabbit model of renal interstitial fibrosis was established. Autologous fibroblasts were cultured, induced and labeled with green fluorescent protein (GFP). These labeled stem cells were transplanted into the renal artery of model animals at 8 weeks. Results Eight weeks following transplantation of induced autologous stem cells, significant reductions (P < 0.05) were observed in serum creatinine (SCr) (14.8 ± 1.9 mmol/L to 10.1 ± 2.1 mmol/L) and blood urea nitrogen (BUN) (119 ± 22 µmol/L to 97 ± 13 µmol/L), indicating improvement in renal function. Conclusions We successfully established a rabbit model of renal interstitial fibrosis and demonstrated that transplantation of induced autologous stem cells can repair kidney damage within 8 weeks. The repair occurred by both inhibition of further development of renal interstitial fibrosis and partial reversal of pre-existing renal interstitial fibrosis. These beneficial effects lead to the development of normal tissue structure and improved renal function. PMID:24367598

Guilty as charged: bugs and drugs in gastric ulcer.

PubMed

Sontag, S J

1997-08-01

Gastric ulcer disease remains a cause of hemorrhage, perforation, outlet obstruction, and death. Recent advances in the understanding of peptic ulcer disease indicate that infection with Helicobacter pylori and ingestion of nonsteroidal anti-inflammatory drugs (NSAIDs) are the cause of almost all gastric and duodenal ulcers. Our therapy, therefore, is in a state of transition: the old acid-suppressive temporary therapy that allows frequent ulcer recurrences and complications is being replaced by curative therapies. The old therapy, by reducing gastric acid secretion or enhancing gastric mucosal defenses, inhibited the cofactors needed for ulcer development. Acid suppression relieved symptoms and healed ulcers, while defense enhancers, such as prostaglandin analogs healed and prevented acute NSAID-induced gastric ulcers. These benefits were maintained, however, only as long as acid-reducing agents or mucosal defense enhancers were continued. On the other hand, curative therapies (such as eradicating H. pylori infection and/or stopping the use of NSAIDs) eliminate the causes of ulcer. Curative combination regimens consisting of antibiotics, ranitidine bismuth citrate, bismuth, and proton pump inhibitors have been approved by the Food and Drug Administration. These new regimens can cure benign gastric ulcer. Unfortunately, we cannot always determine which gastric ulcers are benign, and concern about gastric cancer remains. All gastric ulcers therefore still require biopsy and histological examination. With new treatment regimens, the time may be rapidly approaching when ulcer disease will be "history."

Probiotics and prebiotics in ulcerative colitis.

Derikx, Lauranne A A P; Dieleman, Levinus A; Hoentjen, Frank

2016-02-01

The intestinal microbiota is one of the key players in the etiology of ulcerative colitis. Manipulation of this microflora with probiotics and prebiotics is an attractive strategy in the management of ulcerative colitis. Several intervention studies for both the induction and maintenance of remission in ulcerative colitis patients have been performed. Most of these studies evaluated VSL#3 or E. Coli Nissle 1917 and in general there is evidence for efficacy of these agents for induction and maintenance of remission. However, studies are frequently underpowered, lack a control group, and are very heterogeneous investigating different probiotic strains in different study populations. The absence of well-powered robust randomized placebo-controlled trials impedes the widespread use of probiotics and prebiotics in ulcerative colitis. However, given the promising results that are currently available, probiotics and prebiotics may find their way to the treatment algorithm for ulcerative colitis in the near future.

Biologics in oral medicine: ulcerative disorders.

PubMed

O'Neill, I D; Scully, C

2013-01-01

Inflammatory ulcerative diseases of the oral mucosa are wide ranging but include especially aphthous and aphthous-like ulceration, vesiculobullous disorders and erosive lichen planus (LP). While most patients with these conditions respond to conventional topical and/or systemic immunosuppressive agents, treatment-resistant cases remain challenging. In these, the use of biologics such as tumour necrosis factor alpha (TNF-α) inhibitors or rituximab may be of benefit. This article reviews the use of biologics in ulcerative oral conditions, highlighting potential benefits, adverse effects and principles of use and future developments. TNF-α inhibitors such as infliximab can be effective in inducing resolution in oral aphthous and aphthous-like ulcers and may be an appropriate therapy in those patients in which disease is severe and refractory to, or patients are intolerant of, traditional immunomodulatory regimens. There would also seem support and rationale for use of biologics (mainly rituximab) in pemphigus but not in oral LP or other oral ulcerative conditions. © 2012 John Wiley & Sons A/S.

The National Expert Standard Pressure Ulcer Prevention in Nursing and pressure ulcer prevalence in German health care facilities: a multilevel analysis.

2010-12-01

The objective of this study was to describe the relationship between the German National Expert Standard Pressure Ulcer Prevention and the pressure ulcer prevalence in German nursing homes and hospitals. The patient outcome pressure ulcer does not only depend on individual characteristics of patients, but also on institutional factors. In Germany, National Expert Standards are evidence-based instruments that build the basis of continuing improvement in health care quality. It is expected that after having implemented the National Expert Standard Pressure Ulcer Prevention, the number of pressure ulcers should decrease in health care institutions. The analysed data were obtained from two cross-sectional studies from 2004-2005. A multilevel analysis was performed to show the impact of the National Expert Standard Pressure Ulcer Prevention on pressure ulcer prevalence. A total of 41.5% of hospitals and 38.8% of the nursing homes claimed to use the National Expert Standard in the process of developing their local protocols. The overall pressure ulcer prevalence grade 2-4 was 4.7%. Adjusted for hospital departments, survey year and individual characteristics, there was no significant difference in the prevalence of pressure ulcers between institutions that refer to the National Expert Standard or those referring to other sources in developing their local protocols (OR=1.14, 95% CI=0.90-1.44). There was no empirical evidence demonstrating that local protocols of pressure ulcer prevention based on the National Expert Standard were superior to local protocols which refer other sources of knowledge with regard to the pressure ulcer prevalence. The use of the National Expert Standard Pressure Ulcer Prevention can neither be recommended nor be refused. The recent definition of implementation of Expert Standards should be mandatory for all health care institutions which introduce Expert Standards. © 2010 Blackwell Publishing Ltd.

The Acute Cystitis Symptom Score - ACSS was originally developed in the Uzbek language and has demonstrated high reliability and validity. The study was aimed to develop a Russian version of the ACSS questionnaire and evaluate its psychometric properties. Translation and adaptation of the ACSS questionnaire containing 18 questions, 6 of them - for the typical symptoms of acute cystitis (AC), 4 - for the differential diagnosis; 3 - for the quality of life, and 5 - for the conditions that may affect the choice of treatment, were performed according to the recommendations developed by the Mapi Research Institute. Study involved 83 Russian-speaking women (mean age, 35.6 ±13.7 years); 38 (45.8%) patients were in the main group (patients with AC), and 45 (54.2%) - in the control group (without AC). Medical examination and appropriate treatment of the respondents were conducted in accordance with approved standards. After completing the course of therapy, 19 (50%) patients of the main group came for the control examination. There was statistically significant difference in the scores obtained in the two groups. Score profiles positively correlated with the results of laboratory tests (rho = 0.26-0.48). Cronbach's alpha for the Russian version of the questionnaire was 0.86 (95% CI, 0.81-0.91), area under the curve in the ROC analysis was 0.96. The results of testing the Russian version correspond to those of the original version. The Russian version of the ACSS questionnaire has high. reliability and validity, and can be recommended for clinical research and diagnosis of primary AC, and dynamic monitoring of the effectiveness of the treatment of the Russian-speaking population of patients.

Diabetic foot ulcer (DFU) patients have a greater than twofold increase in mortality compared with nonulcerated diabetic patients. We investigated (a) cause of death in DFU patients, (b) age at death, and (c) relationship between cause of death and ulcer type. This was an eleven-year retrospective study on DFU patients who attended King's College Hospital Foot Clinic and subsequently died. A control group of nonulcerated diabetic patients was matched for age and type of diabetes mellitus. The cause of death was identified from death certificates (DC) and postmortem (PM) examinations. There were 243 DFU patient deaths during this period. Ischaemic heart disease (IHD) was the major cause of death in 62.5% on PM compared to 45.7% on DC. Mean age at death from IHD on PM was 5 years lower in DFU patients compared to controls (68.2 ± 8.7 years versus 73.1 ± 8.0 years, P = 0.015). IHD as a cause of death at PM was significantly linked to neuropathic foot ulcers (OR 3.064, 95% CI 1.003–9.366, and P = 0.049). Conclusions. IHD is the major cause of premature mortality in DFU patients with the neuropathic foot ulcer patients being at a greater risk. PMID:27213157

The Centers for Medicare & Medicaid Services' regulations regarding nonpayment for hospital-acquired conditions such as pressure ulcers have prompted a marked increase in focus on preventive care. Our hospital also used this change in payment policy as an opportunity to strengthen our pressure ulcer prevention practices. We used an 8-spoke prevention wheel to develop and implement practice changes that reduced pressure ulcer incidence from 7.3% to 1.3% in 3 years. Because it is about the journey, we will describe the mechanisms we designed and implemented, and identify strategies that worked or did not work as we promulgated a quality improvement process for pressure ulcer prevention in our large urban hospital center.

Dynamics and changes in the biochemical composition in the interstitial fluid and the muscle water were studied in hemorrhagic shock. The interstitial fluid was collected from implanted perforated capsules. Muscle biopsies were examined with regard to their water content by the steady state magnetic nuclear resonance spectroscopy. The consistent and what appears to be the most significant changes were the fall in the interstitial fluid pressures, the quantitative reduction of muscle water, a sharp fall in the blood and interstitial blood pH, the moderate hyperkalemia and lack of change in blood an interstitial fluid sodium, and the rise in blood glucose levels not accompanied by a rise in the interstitial fluid glucose levels.

The drywall construction trade has in the past been associated with exposure to airborne asbestos fibres. This paper reports a drywall construction worker with 32 years of dust exposure who developed dyspnoea and diminished diffusing capacity, and showed diffuse irregular opacities on chest radiography. He did not respond to treatment with corticosteroids. Open lung biopsy examination showed desquamative interstitial pneumonia. Only a single ferruginous body was seen on frozen section, but tissue examination by electron microscopy showed an extraordinary pulmonary burden of mineral dust with especially high concentrations of chrysotile asbestos fibres. This report emphasises the need to consider asbestos fibre as an agent in the aetiology of desquamative interstitial pneumonia. The coexistent slight interstitial fibrosis present in this case is also considered to have resulted from exposure to mineral dust, particularly ultramicroscopic asbestos fibres. Images PMID:1645584

All patients with non-syphilitic spirochaetal infection were uncircumcised. Non-syphilitic treponemes were seen in only two of 60 uncircumcised men who had urethritis without genital ulceration. In 14 patients with ulcerative balanoposthitis no cause of genital ulceration could be identified. Most patients presented with large, serpiginous, superficial, foul smelling, and tender ulcers, the base of which was purulent with undermined edges. Non-tender inguinal lymphadenopathy was present in seven of 14 patients. One female sexual partner of a patient with non-syphilitic spirochaetal infection had a vaginal infection with non-syphilitic spirochaetes. Images PMID:3949350

This paper highlights the methodology in measuring interstitial pressure in pancreatic adenocarcinoma tumors. A Millar Mikrotip pressure catheter (SPR-671) was used in this study and a system was built to amplify and filter the output signal for data collection. The Millar pressure catheter was calibrated prior to each experiment in a water column at 37°C, range of 0 to 60 inH2O (112 mmHg), resulting in a calibration factor of 33 mV / 1 inH2O. The interstitial pressures measured in two orthotopically grown pancreatic adenocarcinoma tumor were 57 mmHg and 48 mmHg, respectively. Verteporfin uptake into the pancreatic adenocarcinoma tumor was measured using a probe-based experimental dosimeter.

Background In developing countries the prevalence of duodenal ulceration is related to the staple diet and not to the prevalence of Helicobacter pylori. Experiments using animal peptic ulcer models show that the lipid fraction in foods from the staple diets of low prevalence areas gives protection against ulceration, including ulceration due to non-steroidal anti-inflammatory drugs (NSAIDs), and also promotes healing of ulceration. The lipid from the pulse Dolichos biflorus (Horse gram) was highly active and used for further investigations. Further experiments showed the phospholipids, sterol esters and sterols present in Horse gram lipid were gastroprotective. Dietary phospholipids are known to be protective, but the nature of protective sterols in staple diets is not known. The present research investigates the nature of the protective phytosterols. Methods Sterol fractions were extracted from the lipid in Dolichos biflorus and tested for gastroprotection using the rat ethanol model. The fractions showing protective activity were isolated and identification of the components was investigated by Gas Chromatography-Mass Spectrometry (GC-MS). Results The protective phytosterol fraction was shown to consist of stigmasterol, β-sitosterol and a third as yet unidentified sterol, isomeric with β-sitosterol. Conclusions Dietary changes, affecting the intake of protective phospholipids and phytosterols, may reduce the prevalence of duodenal ulceration in areas of high prevalence and may reduce the incidence of recurrent duodenal ulceration after healing and elimination of Helicobacter pylori infection. A combination of phospholipids and phytosterols, such as found in the lipid fraction of ulceroprotecive foods, may be of value in giving protection against the ulcerogenic effect of NSAIDs.

A marginal ulcer developing after an initial operation for gastroduodenal ulcer is a serious threat to the patient, and a challenge to surgeons. Helicobacter pylori is the primary cause of peptic ulcer disease. However, its role in ulcer recurrence, especially of marginal ulcer (MU), after peptic ulcer surgery is unclear. This study aimed to determine any association between H. pylori infection and perforated MU by comparing the prevalence of H. pylori and nonsteroidal anti-inflammatory drugs (NSAIDs) use in patients with perforated (PMU) and in those with nonperforated MU (NPMU). The study retrospectively evaluated the records of 16 patients with PMU who underwent surgical treatment and 24 patients with NPMU who underwent medical treatment in Atatürk University, School of Medicine, Department of General Surgery and Gastroenterology, between January 1995 and December 2004. The rate of H. pylori in the PMU group was significantly higher than that of the NPMU group (P < 0.01). There was a significant relationship between NSAID consumption and PMU compared with NPMU patients (P < 0.01). There was also a significant relationship between NSAID consumption and H. pylori and PMU (P < 0.01). Eradication of H. pylori after the first PMU operation especially in cases with impaired hemodynamics, severe peritoneal contamination, and/or a diameter smaller than 1 cm and avoiding the use of NSAIDs will surely reduce the risk of relapsing ulcers.

Raynaud, digital ulcers and calcinosis are frequent manifestations of patients with systemic sclerosis. Digital ulcers are seen in more than half of the patients with scleroderma. Hospitalizations, ischemic complications and impairment of hand function are frequently observed in patients with digital ulcers, especially if treatment is delayed. Rapid and intensive treatment escalation in patients with scleroderma and refractory Raynaud's phenomenon is one of the most effective preventive action available in order to avoid the development of digital ulcers and tissue loss.

Pressure ulcers are painful and cause discomfort, have a negative effect on quality of life, and are costly to treat. The incidence and severity of preventable pressure ulcers is an important indicator of quality of care; it is essential that healthcare providers monitor prevalence and incidence rates to ensure that care strategies implemented are effective. Frail older people are at increased risk of developing pressure ulcers. This article discusses the complexities of preventing pressure ulcers in frail older people and emphasises the importance of structured educational programmes that incorporate effective clinical leadership and multidisciplinary teamwork.

The objective of this paper was to evaluate effect of laser's biostimulation on the process of healing of crural ulcerations. Three comparative groups of patients, A, B and C, were made at random from the patients with venous crural ulcerations. The group A consisted of 17, the group B 15, the group C 17 patients. The patients in all comparative groups were treated pharmacologically and got compress therapy. Ulcerations at patients in group A were additionally irradiated by light of biostimulation's laser (810 nm) in this way that every time ulcerations got dose of energy 4 J/cm2. The patient's in-group B additionally got blind trial (with placebo in the form of quasi-laserotherapy). The evaluated factors were to estimate how laser's biostimulation causes any changes of the size of the ulcers and of the volume of tissue defect. The speed of changes of size and volume of tissue defect per week was calculated. After the treatment there was statistically significant decrease of size of ulcers in all comparative groups while there was no statistically significant difference between the groups observed. After the treatment there was statistically significant decrease of volume of ulcers only in groups A and C but there was no statistically significant difference between the groups observed.

OBJECTIVE: To review underlying causes of diabetic foot ulceration, provide a practical assessment of patients at risk, and outline an evidence-based approach to therapy for diabetic patients with foot ulcers. QUALITY OF EVIDENCE: A MEDLINE search was conducted for the period from 1979 to 1999 for articles relating to diabetic foot ulcers. Most studies found were case series or small controlled trials. MAIN MESSAGE: Foot ulcers in diabetic patients are common and frequently lead to lower limb amputation unless a prompt, rational, multidisciplinary approach to therapy is taken. Factors that affect development and healing of diabetic patients' foot ulcers include the degree of metabolic control, the presence of ischemia or infection, and continuing trauma to feet from excessive plantar pressure or poorly fitting shoes. Appropriate wound care for diabetic patients addresses these issues and provides optimal local ulcer therapy with débridement of necrotic tissue and provision of a moist wound-healing environment. Therapies that have no known therapeutic value, such as foot soaking and topical antiseptics, can actually be harmful and should be avoided. CONCLUSION: Family physicians are often primary medical contacts for patients with diabetes. Patients should be screened regularly for diabetic foot complications, and preventive measures should be initiated for those at risk of ulceration. PMID:11398715

Peptic ulcer perforation is a serious complication of peptic ulcer disease with a significant morbidity and mortality. To evaluate 76 patients operated for peptic ulcer perforation and analyse the associated factors in Zewditu Memorial Hospital, Addis Ababa from September 2006 to August 2008. A retrospective analysis of medical records of 76 patients who were operated up on for perforated peptic ulcer over a two year period (2006-2008). The male to female ratio was 6.6:1 with a mean age being 31.5 years. The most common presenting symptom was abdominal pain in 76 (100%) patients. History of smoking and khat chewing was documented in 53/64 (82.8%) and 48/64 (75%) of the patients respectively. Twenty five per cent of the patients gave no history of previous peptic ulcer disease. Seventy patients (92.1%) presented after 48 hours of their illness. The mean hospital stay was 14.5 days. Leucocytosis was found in 31.6% of the cases. Sixty five (85.5%) patients had duodenal ulcer perforation. Postoperative complications occurred in 24 (31.6%) patients. Twelve (15.8%) patients died in the hospital. Early presentation of patients and change in life style may reduce morbidity and mortality in patients with peptic ulcer perforation.

Here, we improve the Self-Evolving Atomistic Kinetic Monte Carlo (SEAKMC) algorithm by integrating the Activation Relaxation Technique nouveau (ARTn), a powerful open-ended saddle-point search method, into the algorithm. We use it to investigate the reaction of 37-interstitial 1/2[1 1 1] and 1/2[View the MathML source] loops in FeCr at 10 at.% Cr. They transform into 1/2[1 1 1], 1/2[View the MathML source], [1 0 0] and [0 1 0] 74-interstitial clusters with an overall barrier of 0.85 eV. We find that Cr decoration locally inhibits the rotation of crowdions, which dictates the final loop orientation. Moreover, the final loop orientationmore » depends on the details of the Cr decoration. Generally, a region of a given orientation is favored if Cr near its interface with a region of another orientation is able to inhibit reorientation at this interface more than the Cr present at the other interfaces. Also, we find that substitutional Cr atoms can diffuse from energetically unfavorable to energetically favorable sites within the interlocked 37-interstitial loops conformation with barriers of less than 0.35 eV.« less

This review of the current literature aims to study correlations between the chemical structure and gastric anti-ulcer activity of tannins. Tannins are used in medicine primarily because of their astringent properties. These properties are due to the fact that tannins react with the tissue proteins with which they come into contact. In gastric ulcers, this tannin-protein complex layer protects the stomach by promoting greater resistance to chemical and mechanical injury or irritation. Moreover, in several experimental models of gastric ulcer, tannins have been shown to present antioxidant activity, promote tissue repair, exhibit anti Helicobacter pylori effects, and they are involved in gastrointestinal tract anti-inflammatory processes. The presence of tannins explains the anti-ulcer effects of many natural products. PMID:22489149

Pelton, A.R.

1982-06-01

Recent developments have elucidated the atomistic mechanisms of precipitation of interstitial elements in simple alloy systems. However, in the more technologically important iron base alloys, interstitial phase precipitation is generally not well understood. The present experimental study was therefore designed to test the applicability of these concepts to more complex ferrous alloys. Hence, a comparative study was made of interstitial phase precipitation in ferritic Fe-Si-C and in austenitic phosphorus-containing Fe-Cr-Ni steels. These systems were subjected to a variety of quench-age thermal treatments, and the microstructural development was subsequently characterized by transmission electron microscopy.

Spinal cord injury pressure ulcer treatment: an experience-based approach.

PubMed

Sunn, Gabriel

2014-08-01

Pressure ulcers continue to impact the lives of spinal cord injury patients severely. Pressure ulcers must be accurately staged according to National Pressure Ulcer Advisory recommendations before treatment design. The first priority in treatment of pressure ulcers is offloading. Intact skin ulcers may be treated with noncontact nonthermal low-frequency ultrasound. Superficial pressure ulcers may be treated with a combination of collagenase and foam dressings. Deeper pressure ulcers warrant negative-pressure wound therapy dressings along with biologic adjuncts to fill in wound depth. Discovery and treatment of osteomyelitis is a high priority when initially evaluating pressure ulcers. Surgical intervention must always be considered. Published by Elsevier Inc.

2010-03-01

The diagnosis of bladder pain syndrome/interstitial cystitis (BPS/IC) is challenging, since pathogenetic mechanisms and the definition of clinical relevant parameters are still under lively discussion. The criteria recently proposed by the European Society for the Study of Interstitial Cystitis (ESSIC) define a collective of patients based on the cardinal symptom of bladder pain which is heterogeneous, and therefore cannot receive standardised consistent therapy. Thus an extended diagnosis based on molecular markers seems to be indicated to render individual pharmacotherapy possible, and to contribute to elucidation of BPS/IC pathogenesis. For this purpose we feel the vital need for taking a bladder biopsy. The diagnosis of BPS/IC should rely on 3 "columns": (1) clinical diagnostics; (2) histopathology; (3) molecular diagnostics/protein expression. Since a significant contribution of the 3 functional units of the bladder to the pathophysiology is most evident, the examinations should ideally include urothelium, lamina propria, and detrusor musculature. Generation of receptor profiles of the detrusor muscle represents a first attempt to define a diagnostic tool for the individualisation of BPS/IC pharmacotherapy. Other factors, e.g., beta-hCG expression in the urothelium, need further evaluation. Extended BPS/IC diagnostics could be realistically integrated into routine patient care within a clinic/laboratory network. Georg Thieme Verlag Stuttgart New York.

2015-09-01

Urethral pain syndrome is a symptom complex including dysuria, urinary urgency and frequency, nocturia and persistent or intermittent urethral and/or pelvic pain in the absence of proven infection. These symptoms overlap with several other conditions, such as interstitial cystitis bladder pain syndrome and overactive bladder. Urethral pain syndrome may occur in men but is more frequent in women. The exact etiology is unknown but infectious and psychogenic factors, urethral spasms, early interstitial cystitis, hypoestrogenism, squamous metaplasia as well as gynecological risk factors are discussed. These aspects should be ruled out or confirmed in the diagnostic approach. Despite the assumption of a multifactorial etiology, pathophysiologically there is a common pathway: dysfunctional epithelium of the urethra becomes leaky which leads to bacterial and abacterial inflammation and ends in fibrosis due to the chronic impairment. The therapeutic approach should be multimodal using a trial and error concept: general treatment includes analgesia, antibiotics, alpha receptor blockers and muscle relaxants, antimuscarinic therapy, topical vaginal estrogen, psychological support and physical therapy. In cases of nonresponding patients intravesical and/or surgical therapy should be considered. The aim of this review is to summarize the preliminary findings on urethral pain syndrome and to elucidate the diagnostic and therapeutic options.

Molecular mechanisms of ulcer healing.

PubMed

Tarnawski, A

2000-04-01

An ulcer in the gastrointestinal tract is a deep necrotic lesion penetrating the entire mucosal thickness and muscularis mucosae. Ulcer healing is an active process of filling the mucosal defect with proliferating and migrating epithelial and connective tissue cells. At the ulcer margin, epithelial cells proliferate and migrate onto the granulation tissue to cover (reepithelialize) the ulcer and also invade granulation tissue to reconstruct glandular structures within the ulcer scar. The reepithelialization and reconstruction of glandular structures is controlled by growth factors: trefoil peptides, EGF, HGF, bFGF and PDGF; and locally produced cytokines by regenerating cells in an orderly fashion and integrated manner to ensure the quality of mucosal restoration. These growth factors, most notably EGF, trigger cell proliferation via signal transduction pathways involving EGF-R, adapter proteins (Grb2, Shc and Sos), Ras, Raf1 and MAP (Erk1/Erk2) kinases, which, after translocation to nuclei, activate transcription factors and cell proliferation. Cell migration requires cytoskeletal rearrangements and is controlled by growth factors via Rho/Rac and signaling pathways involving PLC-gamma, PI-3 K and phosphorylation of focal adhesion proteins. Granulation tissue develops at the ulcer base. It consists of connective tissue cells: fibroblasts, macrophages and proliferating endothelial cells forming microvessels under the control of angiogenic growth factors: bFGF, VEGF and angiopoietins, which all promote angiogenesiscapillary vessel formation, essential for the restoration of microvascular network in the mucosa and thus crucial for oxygen and nutrient supply. The major mechanism of activation of angiogenic growth factors and their receptor expression appears to be hypoxia, which activates hypoxia-inducible factor, which binds to VEGF promoter.

Peptic ulcer etiology has been changing because of H. pylori decline. To estimate peptic ulcer prevalence in 10 years-interval and compare the association with H. pylori and use of non-steroidal anti-inflammatory drugs. Methods Records assessment in two periods: A (1997-2000) and B (2007-2010), searching for peptic ulcer, H. pylori infection and non-steroidal anti-inflammatory drugs use. Peptic ulcer occurred in 30.35% in A and in 20.19% in B. H. pylori infection occurred in 73.3% cases in A and in 46.4% in B. Non-steroidal anti-inflammatory drugs use was 3.5% in A and 13.3% in B. Neither condition occurred in 10.4% and 20.5% in A and B respectively. Comparing both periods, we observed reduction of peptic ulcer associated to H. pylori (P=0.000), increase of peptic ulcer related to non-steroidal anti-inflammatory drugs (P=0.000) and idiopathic peptic ulcer (P=0.002). The concurrent association of H. pylori and non-steroidal anti-inflammatory drugs was also higher in B (P=0.002). Rates of gastric ulcer were higher and duodenal ulcer lower in the second period. After 10 years, the prevalence of peptic ulcer decreased, as well as ulcers related to H. pylori whereas ulcers associated to non-steroidal anti-inflammatory drugs increased. There was an inversion in the pattern of gastric and duodenal ulcer and a rise of idiopathic peptic ulcer.

The aim of this study was to investigate the effect of preemptive pantoprazole infusion on early endoscopic findings in patients with acute ulcer bleeding. Records of 333 patients admitted with acute ulcer bleeding were analyzed. Ulcer bleeders were given either 80 mg bolus of pantoprazole followed by continuous infusion of 8 mg per hour or saline infusion until endoscopy. In 93 patients saline infusion whereas in 240 patients bolus plus infusion of pantoprazole was administrated with mean (±SD) durations of 5.45 ± 12.9 hours and 6.9 ± 13.2 hours, respectively (P = 0.29). Actively bleeding ulcers were detected in 46/240 (19.2%) of cases in the pantoprazole group as compared with 23/93 (24.7%) in the saline infusion group (P = 0.26). Different durations of pantoprazole infusion (0–4 hours, >4 hours, and >6 hours) had no significant effect on endoscopic and clinical outcome parameters in duodenal ulcer bleeders. Gastric ulcer bleeders on pantoprazole infusion longer than 4 and 6 hours before endoscopy had actively bleeding ulcers in 4.3% and 5% compared to the 19.5% active bleeding rate in the saline group (P = 0.02 and P = 0.04). Preemptive infusion of high-dose pantoprazole longer than 4 hours before endoscopy decreased the ratio of active bleeding only in gastric but not in duodenal ulcer patients. PMID:23125849

To evaluate the impact of urinary symptoms of Painful Bladder/Pelvic Pain Syndrome and Radiation Cystitis (PBCPPS) on the Quality of Life, and self-esteem of the patient. An observational, multicenter, epidemiological and cross-sectional study was performed on patients with Painful Bladder/Chronic Pelvic Pain Syndrome and Radiation Cystitis. Data was recorded on severity of urinary symptoms and QoL impairment using the PUF Score. The patients evaluated the QoL deterioration grade through the King's Health Questionnaire (KHQ), and the level of their anxiety and self-esteem with the Goldberg's Anxiety Scale (GAS) and Rosenberg's Self-Esteem Scale (RSES), respectively. Post-hoc comparisons were performed between the results of the KHQ of this study and a sample of patients with urinary incontinence (UI). Results on RSES were analyzed with data from the general population and from patients with erectile dysfunction. A total of 530 cases, mostly female patients, who had been diagnosed with PBCPPS, were analyzed. High levels of deterioration in QoL were described: KHQ scores were significantly higher when compared with patients with UI (P<.01). Involvement of self-esteem was higher in patients with RC and men, who obtained scores similar to those of patients with erectile dysfunction. Patients with Painful Bladder Syndrome/Chronic Pelvic Pain Syndrome and Radiation Cystitis present high levels of anxiety, and significant reductions in both quality of life and self-esteem. Especially for men, this affectation is similar to that caused by erectile dysfunction. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

Abstract Although endoscopic ultrasonography (EUS) is the first-choice imaging modality for predicting the invasion depth of early gastric cancer (EGC), the prediction accuracy of EUS is significantly decreased when EGC is combined with ulceration. The aim of present study was to compare the accuracy of EUS and conventional endoscopy (CE) for determining the depth of EGC. In addition, the various clinic-pathologic factors affecting the diagnostic accuracy of EUS, with a particular focus on endoscopic ulcer shapes, were evaluated. We retrospectively reviewed data from 236 consecutive patients with ulcerative EGC. All patients underwent EUS for estimating tumor invasion depth, followed by either curative surgery or endoscopic treatment. The diagnostic accuracy of EUS and CE was evaluated by comparing the final histologic result of resected specimen. The correlation between accuracy of EUS and characteristics of EGC (tumor size, histology, location in stomach, tumor invasion depth, and endoscopic ulcer shapes) was analyzed. Endoscopic ulcer shapes were classified into 3 groups: definite ulcer, superficial ulcer, and ill-defined ulcer. The overall accuracy of EUS and CE for predicting the invasion depth in ulcerative EGC was 68.6% and 55.5%, respectively. Of the 236 patients, 36 patients were classified as definite ulcers, 98 were superficial ulcers, and 102 were ill-defined ulcers, In univariate analysis, EUS accuracy was associated with invasion depth (P = 0.023), tumor size (P = 0.034), and endoscopic ulcer shapes (P = 0.001). In multivariate analysis, there is a significant association between superficial ulcer in CE and EUS accuracy (odds ratio: 2.977; 95% confidence interval: 1.255–7.064; P = 0.013). The accuracy of EUS for determining tumor invasion depth in ulcerative EGC was superior to that of CE. In addition, ulcer shape was an important factor that affected EUS accuracy. PMID:27472672

Little has been published about how to prevent pressure ulcers in severely debilitated, immobile patients in intensive care units. To present a possible prevention strategy for postoperative cardiovascular surgery patients at high risk for development of pressure ulcers. Staff chose to implement air fluidized therapy beds, which provide maximal immersion and envelopment as a measure for preventing pressure ulcers in patients who (1) required vasopressors for at least 24 hours and (2) required mechanical ventilation for at least 24 hours postoperatively. Only 1 of 27 patients had a pressure ulcer develop while on the air fluidized therapy bed (February 2008 through August 2008), and that ulcer was only a stage I ulcer, compared with 40 ulcers in 25 patients before the intervention. Patients spent a mean of 7.9 days on the mattress, and the cost of bed rental was approximately $18000, which was similar to the cost of treatment of 1 pressure ulcer in stage III or IV (about $40000) and was considered cost-effective.

Massage therapy for preventing pressure ulcers.

Pressure ulcers affect approximately 10% of patients in hospitals and the elderly are at highest risk. Several studies have suggested that massage therapy may help to prevent the development of pressure ulcers, but these results are inconsistent. To assess the evidence for the effects of massage compared with placebo, standard care or other interventions for prevention of pressure ulcers in at-risk populations.The review sought to answer the following questions:Does massage reduce the incidence of pressure ulcers of any grade?Is massage safe in the short- and long-term? If not, what are the adverse events associated with massage? We searched the Cochrane Wounds Group Specialised Register (8 January 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 1), Ovid MEDLINE (1946 to 8 January 2015), Ovid MEDLINE (In-Process Other Non-Indexed Citations 8 January 2015), Ovid EMBASE (1974 to 8 January 2015), and EBSCO CINAHL (1982 to 8 January 2015). We did not apply date or language restrictions. We planned to include all randomised controlled trials (RCTs) and quasi-randomised controlled trials (Q-RCTs) that evaluated the effects of massage therapy for the prevention of pressure ulcers. Our primary outcome was the proportion of people developing a new pressure ulcer of any grade. Two review authors independently carried out trial selection. Disagreements were resolved by discussion. No studies (RCTs or Q-RCTs) met the inclusion criteria. Therefore, neither a meta-analysis nor a narrative description of studies was possible. There are currently no studies eligible for inclusion in this review. It is, therefore, unclear whether massage therapy can prevent pressure ulcers.

Temporal comorbidity of mental disorder and ulcerative colitis.

Ulcerative colitis is an inflammatory bowel disease that rarely exists in isolation in affected patients. We examined the association of ulcerative colitis and International Classification of Diseases mental disorder, as well as the temporal comorbidity of three broad International Classification of Diseases groupings of mental disorders in patients with ulcerative colitis to determine if mental disorder is more likely to occur before or after ulcerative colitis. We used physician diagnoses from the regional health zone of Calgary, Alberta, for patient visits from fiscal years 1994 to 2009 for treatment of any presenting concern in that Calgary health zone (763,449 patients) to identify 5113 patients age younger than 1 year to age 92 years (2120 males, average age = 47 years; 2993 females, average age = 48 years) with a diagnosis of ulcerative colitis. The 16-year cumulative prevalence of ulcerative colitis was 0.0058%, or 58 cases per 10,000 persons (95% confidence interval = 56-60 per 10,000). Although the cumulative prevalence of mental disorder in the overall sample was 5390 per 10,000 (53.9%), we found that 4192 patients with ulcerative colitis (82%) also had a diagnosis of a mental disorder. By annual rate of ulcerative colitis, patients with mental disorder had a significantly higher annual prevalence. The mental disorder grouping neuroses/depressive disorders was most likely to arise before ulcerative colitis (odds ratio = 1.87 for males; 2.24 for females). A temporal association was observed between specific groups of International Classification of Diseases mental disorder and ulcerative colitis, indicating a possible etiologic relationship between the disorders or their treatments, or both.

Peptic ulcer has been associated with an increased risk of stroke. This study aimed to evaluate the impacts of peptic ulcer on stroke recurrence and mortality. Patients with first-ever ischemic stroke were retrospectively confirmed with or without a history of peptic ulcer. The primary end point was defined as fatal and nonfatal stroke recurrence. Risks of 1-year fatal and nonfatal stroke recurrence were analyzed with the Kaplan-Meier method. Predictors of fatal and nonfatal stroke recurrence were evaluated with the Cox proportional hazards model. Among the 2577 enrolled patients with ischemic stroke, 129 (5.0%) had a history of peptic ulcer. The fatal and nonfatal stroke recurrence within 1 year of the index stroke was higher in patients with peptic ulcer than in patients without peptic ulcer (12.4% versus 7.2%, P = .030). Cox proportional hazards model detected that age (hazard ratio [HR] = 1.018, 95% confidence interval [CI] 1.005-1.031, P = .008), hypertension (HR = 1.397, 95% CI 1.017-1.918, P = .039), and history of peptic ulcer (HR = 1.853, 95% CI 1.111-3.091, P = .018) were associated with stroke recurrence. Ischemic stroke patients with peptic ulcer may have an increased risk of stroke recurrence. The results emphasize the importance of appropriate prevention and management of peptic ulcer for secondary stroke prevention. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

Eradication of Helicobacter pylori has become part of the standard therapy for peptic ulcer. However, the role of H pylori eradication in perforation of peptic ulcers remains controversial. It is unclear whether eradication of the bacterium confers prolonged ulcer remission after simple repair of perforated peptic ulcer. A systematic review and meta-analysis of randomized controlled trials was performed to evaluate the effects of H pylori eradication on prevention of ulcer recurrence after simple closure of perforated peptic ulcers. The primary outcome to evaluate these effects was the incidence of postoperative ulcers; the secondary outcome was the rate of H pylori elimination. The meta-analysis included five randomized controlled trials and 401 patients. A high prevalence of H pylori infection occurred in patients with perforated peptic ulcers. Eradication of H pylori significantly reduced the incidence of ulcer recurrence at 8 wk (risk ratio 2.97; 95% confidence interval: 1.06-8.29) and 1 y (risk ratio 1.49; 95% confidence interval: 1.10-2.03) postoperation. The rate of H pylori eradication was significantly higher in the treatment group than in the nontreatment group. Eradication therapy should be provided to patients with H pylori infection after simple closure of perforated gastroduodenal ulcers. Copyright © 2013 Elsevier Inc. All rights reserved.

Nutritional care in peptic ulcer

Introduction Peptic ulcer is a lesion of the mucosal lining of the upper gastrointestinal tract characterized by an imbalance between aggressive and protective factors of the mucosa, having H. pylori as the main etiologic factor. Dietotherapy is important in the prevention and treatment of this disease. Aim To update nutritional therapy in adults' peptic ulcer. Methods Exploratory review without restrictions with primary sources indexed in Scielo, PubMed, Medline, ISI, and Scopus databases. Results Dietotherapy, as well as caloric distribution, should be adjusted to the patient's needs aiming to normalize the nutritional status and promote healing. Recommended nutrients can be different in the acute phase and in the recovery phase, and there is a greater need of protein and some micronutrients, such as vitamin A, zinc, selenium, and vitamin C in the recovery phase. In addition, some studies have shown that vitamin C has a beneficial effect in eradication of H. pylori. Fibers and probiotics also play a important role in the treatment of peptic ulcer, because they reduce the side effects of antibiotics and help reduce treatment time. Conclusion A balanced diet is vital in the treatment of peptic ulcer, once food can prevent, treat or even alleviate the symptoms involving this pathology. However, there are few papers that innovate dietotherapy; so additional studies addressing more specifically the dietotherapy for treatment of peptic ulcer are necessary. PMID:25626944

Understanding non ulcer dyspepsia.

Loh, K Y; Siang, T K

2008-06-01

Non ulcer dyspepsia is one of the most common problems encountered in primary care practice. The underlying pathophysiology of non ulcer dyspepsia is not fully understood, but it is known that this condition is associated with H. pylori infection and motility disorder. The presenting abdominal symptoms are non specific: they include bloating, belching, flatulence, excessive fullness after eating and nausea. Psychological condition such as anxiety, depression and stress do play a role in the recurrence of symptoms. Upper GI endoscopy is necessary in patients who presents with alarm symptoms suggestive of possible underlying organic condition before one makes the diagnosis of non ulcer dyspepsia. Pharmacological therapy using H2 receptor antagonist and proton pump inhibitors are effective for symptom relief. Patient's education and supportive care should be part of the management strategy in recurrent chronic dyspepsia.

The semiological characteristics of the ulcerated gastric lesions, benign and malignant, are on study. Its frequency and location is analysed in 32,829 subjects of 40 or more years of age, apparently in good health, finding gastric ulcers in 2.98% been unique in 2.3% and multiple in 0.68%. A symptomatic group of 8,765 people of 40 or more years, showed gastric ulcer in 7.11% been unique in 5.18% and multiple in 1.93%. It is also reported the frequency of gastric cancer in both studied groups, which leads to permanently propose the differential diagnostic with benign lesions, underlying by its frequency those of ulcerated type. The value of the gastric biopsy in differential diagnosis represents finally an aid of major importance because its high yield.

Restoring Psychology's Role in Peptic Ulcer

Overmier, J Bruce; Murison, Robert

2013-01-01

This paper reviews the history of the transition from the belief that gastrointestinal ulcers are caused primarily by psychological factors to the current state of belief that they are caused primarily by infection and argues that neither is fully accurate. We argue that psychological factors play a significant role as predisposing to vulnerability, modulating of precipitation, and sustaining of gastric ulceration. We review data that challenge the assumption of a simple infectious disease model and adduce recent preclinical data that confirm the predisposing, modulatory, and sustaining roles for psychological factors. We note that others, too, are now challenging the adequacy of the contemporary simple bacterial infection model. We hope to replace the competition between psychology and medicine with cooperation in understanding and treating patients suffering gastric ulceration and ulcer. PMID:23457084

Cost consequences due to reduced ulcer healing times - analyses based on the Swedish Registry of Ulcer Treatment.

Resource use and costs for topical treatment of hard-to-heal ulcers based on data from the Swedish Registry of Ulcer Treatment (RUT) were analysed in patients recorded in RUT as having healed between 2009 and 2012, in order to estimate potential cost savings from reductions in frequency of dressing changes and healing times. RUT is used to capture areas of improvement in ulcer care and to enable structured wound management by registering patients with hard-to-heal leg, foot and pressure ulcers. Patients included in the registry are treated in primary care, community care, private care, and inpatient hospital care. Cost calculations were based on resource use data on healing time and frequency of dressing changes in Swedish patients with hard-to-heal ulcers who healed between 2009 and 2012. Per-patient treatment costs decreased from SEK38 223 in 2009 to SEK20 496 in 2012, mainly because of shorter healing times. Frequency of dressing changes was essentially the same during these years, varying from 1·4 to 1·6 per week. The total healing time was reduced by 38%. Treatment costs for the management of hard-to-heal ulcers can be reduced with well-developed treatment strategies resulting in shortened healing times as shown in RUT. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Background/Aims BK virus (BKV) has been associated with late-onset hemorrhagic cystitis (HC) in recipients of hematopoietic stem cell transplantation (HSCT). Cidofovir has been used at higher doses (3 to 5 mg/kg/wk) with probenecid prophylaxis; however, cidofovir may result in nephrotoxicity or cytopenia at high doses. Methods Allogeneic HSCT recipients with BKV-associated HC are treated with 1 mg/kg intravenous cidofovir weekly at our institution. A microbiological response was defined as at least a one log reduction in urinary BKV viral load, and a clinical response was defined as improvement in symptoms and stability or reduction in cystitis grade. Results Eight patients received a median of 4 weekly (range, 2 to 11) doses of cidofovir. HC occurred a median 69 days (range, 16 to 311) after allogeneic HSCT. A clinical response was detected in 7/8 patients (86%), and 4/5 (80%) had a measurable microbiological response. One patient died of uncontrolled graft-versus-host disease; therefore, we could not measure the clinical response to HC treatment. One microbiological non-responder had a stable BKV viral load with clinical improvement. Only three patients showed transient grade 2 serum creatinine toxicities, which resolved after completion of concomitant calcineurin inhibitor treatment. Conclusions Weekly intravenous low-dose cidofovir without probenecid appears to be a safe and effective treatment option for patients with BKV-associated HC. PMID:25750563

Protocols for pressure ulcer prevention: are they evidence-based?

PubMed

Chaves, Lidice M; Grypdonck, Mieke H F; Defloor, Tom

2010-03-01

This study is a report of a study to determine the quality of protocols for pressure ulcer prevention in home care in the Netherlands. If pressure ulcer prevention protocols are evidence-based and practitioners use them correctly in practice, this will result a reduction in pressure ulcers. Very little is known about the evidence-based content and quality of the pressure ulcer prevention protocols. In 2008, current pressure ulcer prevention protocols from 24 home-care agencies in the Netherlands were evaluated. A checklist developed and validated by two pressure ulcer prevention experts was used to assess the quality of the protocols, and weighted and unweighted quality scores were computed and analysed using descriptive statistics. The 24 pressure ulcer prevention protocols had a mean weighted quality score of 63.38 points out of a maximum of 100 (sd 5). The importance of observing the skin at the pressure points at least once a day was emphasized in 75% of the protocols. Only 42% correctly warned against the use of materials that were 'less effective or that could potentially cause harm'. Pressure ulcer prevention commands a reasonable amount of attention in home care, but the incidence of pressure ulcers and lack of a consistent, standardized document for use in actual practice indicate a need for systematic implementation of national pressure ulcer prevention standards in the Netherlands to ensure adherence to the established protocols.

2012-05-01

To elucidate the patterns of interstitial lung disease during everolimus treatment in patients with metastatic renal cell carcinoma, we reviewed seven cases of everolimus-induced interstitial lung disease. Seven patients with metastatic renal cell carcinoma, which continued to progress despite treatment with sunitinib or sorafenib, developed interstitial lung disease after treatment with everolimus. Chest X-ray demonstrated diffuse infiltrates in lung fields, and chest computed tomography showed bilateral reticular and ground-glass opacities. Serum levels of lactate dehydrogenase (7/7), C-reactive protein (6/7), pulmonary surfactant associated protein D (1/7) and Krebs von den Lungen 6 (5/7) were elevated. The bronchoalveolar lavage fluid obtained from four patients with Grade 3 interstitial lung disease showed lymphocytosis. The transbronchial lung biopsy specimens showed interstitial lymphocytic infiltration and septal thickening of alveolar walls. In two cases with mild interstitial lung disease, the everolimus therapy was successfully continued. In four cases with Grade 3 interstitial lung disease, the drug was discontinued and steroid therapy was initiated. Pulmonary symptoms and radiological abnormalities resolved within 2 months. Serum Krebs von den Lungen 6 was elevated compared with baseline in all cases with interstitial lung disease. Some patients who developed mild interstitial lung disease during everolimus treatment could continue to receive the treatment. Even when severe interstitial lung disease developed, withdrawal of the drug and short-term use of high-dose steroids resulted in rapid recovery. Prompt recognition of interstitial lung disease exacerbation as well as exclusion of progressive disease or infection is of primary importance.

A Clinical Approach to Vulvar Ulcers.

2017-09-01

This article discusses the differential diagnosis of vulvar ulcers and describes a general clinical approach to this common but nonspecific examination finding. The differential diagnosis includes sexually and nonsexually transmitted infections, dermatitides, trauma, neoplasms, hormonally induced ulcers, and drug reactions. Patient history and physical examination provide important clues to the cause of a vulvar ulcer. However, laboratory testing is usually required for accurate diagnosis because the clinical presentation is often nonspecific and may be atypical due to secondary conditions.

2018-05-01

Sarcoidosis affects multiple organs including lung, heart and kidney. Sarcoidosis causes hypercalcemia, hypergammaglobulinemia, and rarely, granulomatous interstitial nephritis, resulting in renal stromal damage. Granulomatous interstitial nephritis is characterized as interstitial nephritis with noncaseating epithelioid granulomas. Diagnosing granulomatous interstitial nephritis before patient's death is challenging; hence, only few cases proven by renal biopsy have been reported till date. We present a case of acute kidney injury caused by granulomatous interstitial nephritis as a renal manifestation of sarcoidosis proven by renal biopsy, which can be confirmed by 18 F-fluorodeoxyglucose positron emission tomography/computed tomography. Glucocorticoid therapy was helpful for improving and maintaining her renal function over a 6-year period.

Ulcerative colitis with acute pleurisy

PubMed Central

Lu, Shuming; Wang, Lihua; Zhang, Weisheng; Zhang, Zhuqing; Liu, Lina; Wang, Yingde; Meng, Hua

2017-01-01

Abstract Rationale: Inflammatory bowel diseases (IBD), including ulcerative colitis (UC) and Crohn's disease, are associated with a large number of extraintestinal manifestations. Pulmonary manifestations are infrequently seen in patients with IBD. Moreover, serositis including pleural and pericardial manifestations in UC is rare. Patient concerns: We report a case of UC with acute pleurisy in a 43-year-old man; review literature; and discuss the diagnosis, differential diagnosis, and treatment. Diagnoses: Active duodenal ulcer was found using gastroscopy. Multiple ulcers in segmented pattern were noticed in the left hemi-colon using colonoscopy. An UC in active stage was confirmed subsequently by histology. Intervention: The patient was treated with bifidobacterium tetravaccine tablets, oral mesalazine and mesalazine enemas. The omeprazole and mucosal protective agents were given to treat the duodenal ulcer. Outcomes: As follow-up, the therapy including oral mesalazine and infliximab regularly was continued and the patient condition was stabilized. Main lesson: Pulmonary involvement should be considered in patients who develop pleurisy in UC. Infliximab is considered the better available treatment for patients presenting with pleurisy in UC.

Although this article is a stand-alone article, it sets the scene for later articles in this issue. Pressure ulcers are considered to be a largely preventable problem, and yet despite extensive training and the expenditure of a large amount of resources, they persist. This article reviews the current understanding of pressure ulcer aetiology: pressure, shear and microclimate. Individual risk factors for pressure ulceration also need to be understood in order to determine the level of risk of an individual. Such an assessment is essential to determine appropriate prevention strategies. The main prevention strategies in terms of reducing pressure and shear and managing microclimate are studied in this article. The problem of pressure ulceration related to medical devices is also considered as most of the standard prevention strategies are not effective in preventing this type of damage. Finally, the possibility of using dressings as an additional preventive strategy is raised along with the question: is there enough evidence to support their use? © 2013 The Authors.

Current and emerging biologics for ulcerative colitis.

PubMed

Park, Sung Chul; Jeen, Yoon Tae

2015-01-01

Conventional medical treatment for ulcerative colitis can have limited efficacy or severe adverse reactions requiring additional treatment or colectomy. Hence, different biological agents that target specific immunological pathways are be-ing investigated for treating ulcerative colitis. Anti-tumor necrosis factor (TNF) agents were the first biologics to be used for treating inflammatory bowel disease. For example, infliximab and adalimumab, which are anti-TNF agents, are be-ing used for treating ulcerative colitis. Recently, golimumab, another anti-TNF agent, and vedolizumab, an anti-adhesion therapy, have been approved for ulcerative colitis by the U.S. Food and Drug Administration. In addition, new medications such as tofacitinib, a Janus kinase inhibitor, and etrolizumab, another anti-adhesion therapy, are emerging as therapeutic agents. Therefore, there is a need for further studies to select appropriate patient groups for these biologics and to improve the outcomes of ulcerative colitis treatment through appropriate medical usage.

PRESSURE ULCER PREVENTION: FUNDAMENTALS FOR BEST PRACTICE.

Collier, Mark

2016-01-01

This introduction has highlighted both the complex nature of the aetiology of pressure ulcer development and the complex nature of the assessment process intended to identify those patients who are or might be at an enhanced risk of pressure ulcer development. The latter statement assumes that all patients cared for in any healthcare setting are vulnerable to pressure ulcer development. Whilst it is acknowledged that the use of a risk assessment tool can be important in an overall pressure ulcer prevention strategy, it is important that the limitations of these tools are acknowledged and that they are not an finite assessment in themselves and that they should be used by a practitioner with a fundamental breadth of relevant knowledge and an appreciation of the range of appropriate preventative equipment/techniques available and the role of the multi-disciplinary team in the prevention of all avoidable pressure ulcers.

The behaviour of stacking fault energy upon interstitial alloying.

Stacking fault energy is one of key parameters for understanding the mechanical properties of face-centered cubic materials. It is well known that the plastic deformation mechanism is closely related to the size of stacking fault energy. Although alloying is a conventional method to modify the physical parameter, the underlying microscopic mechanisms are not yet clearly established. Here, we propose a simple model for determining the effect of interstitial alloying on the stacking fault energy. We derive a volumetric behaviour of stacking fault energy from the harmonic approximation to the energy-lattice curve and relate it to the contents of interstitials. The stacking fault energy is found to change linearly with the interstitial content in the usual low concentration domain. This is in good agreement with previously reported experimental and theoretical data.

This article discusses the clinical evaluation and approach to patients with 3 complex ulcerative vulvar conditions: hidradenitis suppurativa, metastatic Crohn disease of the vulva, and aphthous ulcers. These conditions are particularly challenging to medical providers because, although each is known to present with nonspecific examination findings that vary in morphology, the predominance of the diagnosis is based on clinical examination and exclusion of a wide variety of other conditions. Care of patients with these conditions is further complicated by the lack of therapeutic data and the significant impact these conditions have on quality of life. Copyright © 2017 Elsevier Inc.

Acute Exacerbation in Interstitial Lung Disease

PubMed Central

Leuschner, Gabriela; Behr, Jürgen

2017-01-01

Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) has been defined as an acute, clinically significant deterioration that develops within less than 1 month without obvious clinical cause like fluid overload, left heart failure, or pulmonary embolism. Pathophysiologically, damage of the alveoli is the predominant feature of AE-IPF which manifests histopathologically as diffuse alveolar damage and radiologically as diffuse, bilateral ground-glass opacification on high-resolution computed tomography. A growing body of literature now focuses on acute exacerbations of interstitial lung disease (AE-ILD) other than idiopathic pulmonary fibrosis. Based on a shared pathophysiology it is generally accepted that AE-ILD can affect all patients with interstitial lung disease (ILD) but apparently occurs more frequently in patients with an underlying usual interstitial pneumonia pattern. The etiology of AE-ILD is not fully understood, but there are distinct risk factors and triggers like infection, mechanical stress, and microaspiration. In general, AE-ILD has a poor prognosis and is associated with a high mortality within 6–12 months. Although there is a lack of evidence based data, in clinical practice, AE-ILD is often treated with a high dose corticosteroid therapy and antibiotics. This article aims to provide a summary of the clinical features, diagnosis, management, and prognosis of AE-ILD as well as an update on the current developments in the field. PMID:29109947

Abstract Background: Pressure ulcers often seriously affect the quality of life of patients. Moist Exposed Burn Ointment (MEBO) has been developed to treat patients with pressure ulcers. The present study aimed to evaluate the efficacy and safety of MEBO in the treatment of pressure ulcers in Chinese patients. Methods: Seventy-two patients with pressure ulcers were randomly assigned to 2 groups who received a placebo or MEBO for 2 months. The primary outcomes included the wound surface area (WSA) and pressure ulcer scale for healing (PUSH) tool. The secondary outcomes included a visual analog scale (VAS), questionnaire of ulcer status, and adverse effects. Results: Sixty-seven patients completed the study. After 2 months of treatment, the difference of mean change from the baseline was greater for MEBO (vs placebo) for WSA mean (SD) −6.0 (−8.8, −3.3), PUSH Tool −2.6 (−4.7, −1.5), and VAS score −2.9 (−4.4, −1.7). On the basis of the questionnaire, the pressure ulcers were “completely healed” (50.0% vs 16.7%) (P < .05) in patients after 2 months of treatment with MEBO versus placebo. No major adverse effects were found in the 2 groups. Conclusion: We showed that MEBO is effective and well tolerated for improving wound healing in Chinese patients with pressure ulcers.

Digital ulcers (DU) are the most common vascular complication of systemic sclerosis (SSc). We compared the characteristics between patients with prior or current DU with those never affected and evaluated whether a history of DU may be a predictor of vascular, organ involvement, and/or death in patients with SSc. Data from SSc patients with or without prior or current DU were collected by 19 referral centers in an ongoing registry of Spanish SSc patients, named Registro de ESCLErodermia (RESCLE). Demographics, organ involvement, autoimmunity features, nailfold capillary pattern, survival time, and causes of death were analyzed to identify DU related characteristics and survival of the entire series and according to the following cutaneous subsets-diffuse cutaneous SSc (dcSSc), limited cutaneous SSc (lcSSc), and SSc sine scleroderma (ssSSc). Out of 1326, 552 patients enrolled in the RESCLE registry had prior or current DU, 88% were women, the mean age was 50 ± 16 years, and the mean disease duration from first SSc symptom was 7.6 ± 9.6 years. Many significant differences were observed in the univariate analysis between patients with and without prior/current DU. Multivariate analysis identified that history of prior/current DU in patients with SSc was independently associated to younger age at SSc diagnosis, diffuse cutaneous SSc, peripheral vascular manifestations such Raynaud's phenomenon, telangiectasia, and acro-osteolysis but no other vascular features such as pulmonary arterial hypertension or scleroderma renal crisis. DU was also associated to calcinosis cutis, interstitial lung disease, as well as worse survival. Multivariate analysis performed in the cutaneous subsets showed that prior/current DU were independently associated: (1) in dcSSc, to younger age at SSc diagnosis, presence of telangiectasia and calcinosis and rarely a non-SSc pattern on nailfold capillaroscopy; (2) in lcSSc, to younger age at SSc diagnosis, presence of Raynaud's phenomenon as

Budesonide is a high-potency, second-generation corticosteroid designed to minimize systemic adverse consequences of conventional corticosteroids. We performed 2 randomized, phase 3 trials to evaluate the ability of budesonide rectal foam, formulated to optimize retention and provide uniform delivery of budesonide to the rectum and distal colon, to induce remission in patients with ulcerative proctitis or ulcerative proctosigmoiditis. Two identically designed, randomized, double-blind, placebo-controlled trials evaluated the efficacy of budesonide foam for induction of remission in 546 patients with mild to moderate ulcerative proctitis or ulcerative proctosigmoiditis who received budesonide foam 2 mg/25 mL twice daily for 2 weeks, then once daily for 4 weeks, or placebo. Remission at week 6 occurred significantly more frequently among patients receiving budesonide foam than placebo (Study 1: 38.3% vs 25.8%; P = .0324; Study 2: 44.0% vs 22.4%; P < .0001). A significantly greater percentage of patients receiving budesonide foam vs placebo achieved rectal bleeding resolution (Study 1: 46.6% vs 28.0%; P = .0022; Study 2: 50.0% vs 28.6%; P = .0002) and endoscopic improvement (Study 1: 55.6% vs 43.2%; P = .0486; Study 2: 56.0% vs 36.7%; P = .0013) at week 6. Most adverse events occurred at similar frequencies between groups, although events related to changes in cortisol values were reported more frequently with budesonide foam. There were no cases of clinically symptomatic adrenal insufficiency. Budesonide rectal foam was well tolerated and more efficacious than placebo in inducing remission in patients with mild to moderate ulcerative proctitis and ulcerative proctosigmoiditis.

Nowadays, pressure ulcers are a mayor health problem with serious consequences for the patient, directly influence by the increase of morbid-mortality and the detriment of the quality of life. Today we know that the best care for pressure ulcers is the prevention and every effort must be oriented in this direction, specially when it is estimated that almost the 95% of the pressure ulcers are preventable and a 60% of the occasions are initiated and developed in hospital. The study's objective is to promote healing of ulcers with a joint technical nursing care and the application of electric current by physiotherapist. This is a descriptive research design and intervention. The sample is composed grade IV ulcer patients who are admitted to the high level of nursing care unit in Complejo Asistencial Benito Menni (Ciempozuelos-Madrid). These patients have different associated pathologies and the study shows the process from the beginning of the ulcer until the end of treatment. The most relevant results show that the application of electric currents favors nursing techniques, promoting a better and faster cleaning, vascularization and subsequent the healing of ulcers.

Third compartment ulcers in the llama.

The diagnosis of third compartment ulcers in the llama and alpaca is largely one of exclusion. Clinical signs may include mild to severe colic, inappetence, decreased fecal output, bruxism, and depression. Abdominocentesis results are usually unremarkable if C3 perforation has not occurred but reflective of a generalized peritonitis if full thickness ulceration has occurred. The H-2 receptor antagonists cimetidine and ranitidine do not suppress C3 acid production for a significant period of time and are of questionable efficacy in the management of C3 ulcers.

Two components represent Fe atoms substituting Mg as Fe2+ and Fe3+, respectively; a third component is due to Fe in a strongly implantation-induced disturbed region. The fourth component, which is the focus of this paper, can be assigned to Fe at an interstitial site. Comparison of its measured isomer shift with ab initio calculations suggests that the interstitial Fe is located on, or close to, the face of the rock-salt MgO structure. To harmonize such an assignment with the measured near-zero quadrupole interaction a local motion process (cage motion) of the Fe has to be stipulated. The relation of such a local motion as a starting point for long range diffusion is discussed.

Controlled trial of Iodosorb in chronic venous ulcers.

Cadexomer iodine (Iodosorb) is a hydrophilic starch powder containing iodine, which is a suitable dressing for granulating wounds such as venous ulcers. A total of 61 outpatients with chronic venous ulcers participated in a randomised optional crossover trial using cadexomer iodine or a standard dressing for their ulcers. The trial lasted for 24 weeks or until the ulcer had healed. Two patients withdrew during the course of the trial. Both treatments were highly effective, but the epithelium of ulcers dressed with cadexomer iodine grew again significantly faster (p less than 0.001). At the midpoint of the trial (12th week) 13 of 30 patients receiving standard treatment were changed to cadexomer iodine, while only three of 29 receiving cadexomer iodine changed to the standard dressing (p less than 0.02). In most cases ulcers were dressed and rebandaged daily by the patients themselves after instruction and supervision. This may be better than having dressings and bandages applied by professionals less regularly. PMID:3926169

Dressings and topical agents for arterial leg ulcers.

PubMed

Forster, Rachel; Pagnamenta, Fania

2015-06-29

It is estimated that people in industrialised countries have a 1% chance of suffering from a leg ulcer at some time in their life. The majority of leg ulcers are associated with circulation problems; poor blood return in the veins causes venous ulcers (around 70% of ulcers) and poor blood supply to the legs causes arterial ulcers (around 22% of ulcers). Treatment of arterial leg ulcers is directed towards correcting the poor arterial blood supply, for example by correcting arterial blockages (either surgically or pharmaceutically). If the blood supply has been restored, these arterial ulcers can heal following principles of good wound care. Dressings and topical agents make up a part of good wound care for arterial ulcers but there are many products available and it is unclear what impact these have on ulcer healing. This is an update of a review first published in 2003. To determine whether topical agents and wound dressings affect healing in arterial ulcers. To compare healing rates, patient-centred outcomes and costs between wound dressings and topical agents. For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched November 2014) and The Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library) (2014, Issue 10). Randomised controlled trials (RCTs), or controlled clinical trials (CCTs) evaluating dressings and topical agents in the treatment of arterial leg ulcers were eligible for inclusion. The participants had to have ulcers that were described as arterial, and the time to healing, proportion completely healed, or rate of reduction in ulcer area had to be reported. All wound dressings and topical agents were eligible for inclusion in this review. The two review authors independently extracted information on the participants' characteristics, the interventions, and outcomes using a standardised data extraction form.

Compression stockings for treating venous leg ulcers: measurement of interface pressure under a new ulcer kit.

PubMed

Partsch, B; Partsch, H

2008-01-01

The aim of this study was to measure the interface pressure of a newly designed two-layer compression stocking (Mediven ulcer kit Medi QMBH, Bayreuth, Germany) in different body positions and to compare the values with those obtained with another two-layer product. Interface pressure was measured on the distal medial leg in 16 legs of volunteers, with the basic layer alone and with the whole stocking kit in the supine, sitting and standing position for both stocking systems. The literature concerning ulcer-healing rates is reviewed. Mediven ulcerkit produced statistically significant higher pressure values than the ulcer stocking with a median resting value of 35.5 mmHg in the supine and 42.5 mmHg in the standing position. The pressure while standing comes close to values exerted by bandages. The basic layer alone applies a pressure of 20.5 mmHg. Especially designed compression stockings exerting sufficient interface pressure may be indicated in patients with small ulcers of short duration.

Alveolar epithelial cells undergo epithelial-mesenchymal transition in acute interstitial pneumonia: a case report

PubMed Central

2014-01-01

Background Acute interstitial pneumonia is a rare interstitial lung disease that rapidly progresses to respiratory failure or death. Several studies showed that myofibroblast plays an important role in the evolution of diffuse alveolar damage, which is the typical feature of acute interstitial pneumonia. However, no evidence exists whether alveolar epithelial cells are an additional source of myofibroblasts via epithelial-mesenchymal transition in acute interstitial pneumonia. Case presentation In this report, we present a case of acute interstitial pneumonia in a previously healthy 28-year-old non-smoking woman. Chest high-resolution computed tomography scan showed bilateral and diffusely ground-glass opacification. The biopsy was performed on the fifth day of her hospitalization, and results showed manifestation of acute exudative phase of diffuse alveolar damage characterized by hyaline membrane formation. On the basis of the preliminary diagnosis of acute interstitial pneumonia, high-dose glucocorticoid was used. However, this drug showed poor clinical response and could improve the patient’s symptoms only during the early phase. The patient eventually died of respiratory dysfunction. Histological findings in autopsy were consistent with the late form of acute interstitial pneumonia. Conclusions The results in this study revealed that alveolar epithelial cells underwent epithelial-mesenchymal transition and may be an important origin of myofibroblasts in the progression of acute interstitial pneumonia. Conducting research on the transformation of alveolar epithelial cells into myofibroblasts in the lung tissue of patients with acute interstitial pneumonia may be beneficial for the treatment of this disease. However, to our knowledge, no research has been conducted on this topic. PMID:24755111

Populations of subplate and interstitial neurons in fetal and adult human telencephalon.

In the adult human telencephalon, subcortical (gyral) white matter contains a special population of interstitial neurons considered to be surviving descendants of fetal subplate neurons [Kostovic & Rakic (1980) Cytology and the time of origin of interstitial neurons in the white matter in infant and adult human and monkey telencephalon. J Neurocytol9, 219]. We designate this population of cells as superficial (gyral) interstitial neurons and describe their morphology and distribution in the postnatal and adult human cerebrum. Human fetal subplate neurons cannot be regarded as interstitial, because the subplate zone is an essential part of the fetal cortex, the major site of synaptogenesis and the 'waiting' compartment for growing cortical afferents, and contains both projection neurons and interneurons with distinct input-output connectivity. However, although the subplate zone is a transient fetal structure, many subplate neurons survive postnatally as superficial (gyral) interstitial neurons. The fetal white matter is represented by the intermediate zone and well-defined deep periventricular tracts of growing axons, such as the corpus callosum, anterior commissure, internal and external capsule, and the fountainhead of the corona radiata. These tracts gradually occupy the territory of transient fetal subventricular and ventricular zones.The human fetal white matter also contains distinct populations of deep fetal interstitial neurons, which, by virtue of their location, morphology, molecular phenotypes and advanced level of dendritic maturation, remain distinct from subplate neurons and neurons in adjacent structures (e.g. basal ganglia, basal forebrain). We describe the morphological, histochemical (nicotinamide-adenine dinucleotide phosphate-diaphorase) and immunocytochemical (neuron-specific nuclear protein, microtubule-associated protein-2, calbindin, calretinin, neuropeptide Y) features of both deep fetal interstitial neurons and deep (periventricular

Pressure ulcer prevention in care home settings.

Ellis, Michael

2017-03-31

Pressure ulcer prevention in the care home setting can be challenging and is often compromised by a lack of access to education and resources. There are measures that have been shown to consistently improve outcomes in pressure ulcer prevention including assessment of the patient and their individual risks, delivery of a consistent plan of care that meets patients' needs, and regular evaluation to identify shortfalls. In addition, there should be a robust approach to investigating events that lead to a person developing a pressure ulcer and that information should be used to improve future practice. Pressure ulcer prevention in care homes is achievable and nurses should all be aware of the necessary measures detailed in this article.

In vivo interstitial glucose characterization and monitoring in the skin by ATR-FTIR spectroscopy

Successful development of real-time non-invasive glucose monitoring would represent a major advancement not only in the treatment and management of patients with diabetes mellitus and carbohydrate metabolism disorders, but also for understanding in those biochemical, metabolic and (patho-)physiological processes of glucose at the molecular level in vivo. Here, ATR-FTIR spectroscopy technique has been challenged not only for in vivo measurement of interstitial glucose levels, but also for their non-invasive molecular qualitative and quantitative comparative characterization in the skin tissue. The results, based on calculated mean values of determined 5 glucose-specific peaks in the glucose-related 1000-1160 cm-1 region, showed intra- and inter-subject differences in interstitial glucose activity levels with their changes at different times and doses of OGTT, while raising questions about the relationships between interstitial and blood glucose levels. In conclusion, the introduction of ATR-FTIR spectroscopy technique has opened up an access to the interstitial fluid space in the skin tissue for interstitial glucose characterization and monitoring in vivo. Though interstitial versus blood glucose monitoring has different characteristics, it can be argued that accurate and precise measurements of interstitial glucose levels may be more important clinically.

Diffuse Alveolar Damage: A Common Phenomenon in Progressive Interstitial Lung Disorders

PubMed Central

Kaarteenaho, Riitta; Kinnula, Vuokko L.

2011-01-01

It has become obvious that several interstitial lung diseases, and even viral lung infections, can progress rapidly, and exhibit similar features in their lung morphology. The final histopathological feature, common in these lung disorders, is diffuse alveolar damage (DAD). The histopathology of DAD is considered to represent end stage phenomenon in acutely behaving interstitial pneumonias, such as acute interstitial pneumonia (AIP) and acute exacerbations of idiopathic pulmonary fibrosis (IPF). Acute worsening and DAD may occur also in patients with nonspecific interstitial pneumonias (NSIPs), and even in severe viral lung infections where there is DAD histopathology in the lung. A better understanding of the mechanisms underlying the DAD reaction is needed to clarify the treatment for these serious lung diseases. There is an urgent need for international efforts for studying DAD-associated lung diseases, since the prognosis of these patients has been and is still dismal. PMID:21637367

Disseminated Lyme disease presenting with nonsexual acute genital ulcers.

Finch, Justin J; Wald, Jenna; Ferenczi, Katalin; Khalid, Saima; Murphy, Michael

2014-11-01

Nonsexual acute genital ulceration (NAGU) is a rare vulvar skin condition typically affecting girls and young women, characterized by acute onset of singular or multiple painful vaginal ulcers. The etiology of this ulcerative dermatosis has not been identified, although it has been associated with systemic infections. To our knowledge, this is the first report of an association with Lyme disease. A case of a woman with early disseminated Lyme disease presenting with NAGU is reported. A thorough workup ruled out other causes of genital ulceration, and the ulcers completely resolved after treatment with topical steroids and oral doxycycline. Although the etiology of NAGU is unknown, the vulvar ulcers may result from an exuberant immune response to infection. Most patients with NAGU exhibit nonspecific symptoms such as myalgias and fever, suggesting an infectious agent, but the majority have no identifiable pathogen. In addition to previously reported associations with systemic infection, which are reviewed herein, Lyme disease should be considered in women presenting with acute-onset genital ulcers.

Objective The objective of this study was to assess whether there are racial and ethnic disparities in the time to development of a pressure ulcer and number of pressure ulcer treatments in individuals aged 65 and older after nursing home admission. Method Multi-level predictors of time to a pressure ulcer from three national surveys were analyzed using Cox proportional hazards regression for White Non-Hispanic residents. Using the Peters–Belson method to assess for disparities, estimates from the regression models were applied to American Indians/Alaskan Natives, Asians/ Pacific Islanders, Blacks, and Hispanics separately resulting in estimates of expected outcomes as if they were White Non-Hispanic, and were then compared with their observed outcomes. Results More Blacks developed pressure ulcers sooner than expected. No disparities in time to a pressure ulcer disadvantaging other racial/ethnic groups were found. There were no disparities in pressure ulcer treatment for any group. Discussion Reducing disparities in pressure ulcer development offers a strategy to improve the quality of nursing home care.

The aims of the study were to determine: (1) Jordanian nurses' level of knowledge of pressure ulcer prevention and treatment of hospitalized patients based on guidelines for pressure ulcer prevention and treatment. (2) Frequency of utilization of pressure ulcer prevention and treatment interventions in clinical practice. (3) Variables that are associated with nurses' utilization of pressure ulcer prevention and treatment interventions. Pressure ulcers are common and previous studies have shown education, knowledge and attitude affect implementation of interventions. A cross-sectional survey design was used to collect data from 460 nurses between June 2010 and November 2010. We used a questionnaire, which was informed by earlier work and guidelines, to collect data about nurses' knowledge and practice of pressure ulcer prevention and treatment. Knowledge and education show an association with implementation of prevention, and demographic variables do not. Similarly knowledge and type of hospital showed an association with implementing treatment. Of concern the use of "donuts" and massage are reported in use. Although pressure ulcer care is well known by nurses, inappropriate pressure ulcer interventions were reported in use. Copyright © 2013 Tissue Viability Society. Published by Elsevier Ltd.

Pressure ulcer guideline development and dissemination in Europe.

To explore the current state of pressure ulcer guideline development and dissemination, from national to local level (i.e. nursing homes) in six European countries: England, Germany, Italy, the Netherlands, Portugal and Sweden. Pressure ulcers are a persistent problem in healthcare institutions. Their prevalence is influenced by many factors, one of them being the development and dissemination of pressure ulcer guidelines. These are difficult and complex processes and it is not clear whether they differ between European countries. Literature review and semi-structured interviews. Interviews were conducted in six countries at national and nursing home level. Four countries had national pressure ulcer prevention and treatment guidelines. Portugal had no national guidelines and Sweden had shifted the responsibility to regional level. All participating nursing homes had pressure ulcer guidelines except those in Portugal. Control and monitoring of guideline dissemination was carried out only in Sweden and England. All countries studied have national or regional pressure ulcer prevention and treatment guidelines, except Portugal. Portugal is also the only country where none of the nursing homes included had pressure ulcer guidelines. Because the dissemination of such guidelines does not imply actual implementation, further research should focus on the implementation process. Clinical guidelines, like pressure ulcer guidelines, are important tools in guiding the care processes in healthcare institutions. Successful dissemination of guidelines from national level to individual healthcare institutions is a first and necessary step in actually applying them. Monitoring of the guideline dissemination process is therefore essential.

Is postural tremor size controlled by interstitial potassium concentration in muscle?

PubMed Central

Lakie, M; Hayes, N; Combes, N; Langford, N

2004-01-01

Objectives: To determine whether factors associated with postural tremor operate by altering muscle interstitial K+. Methods: An experimental approach was used to investigate the effects of procedures designed to increase or decrease interstitial K+. Postural physiological tremor was measured by conventional means. Brief periods of ischaemic muscle activity were used to increase muscle interstitial K+. Infusion of the ß2 agonist terbutaline was used to decrease plasma (and interstitial) K+. Blood samples were taken for the determination of plasma K+. Results: Ischaemia rapidly reduced tremor size, but only when the muscle was active. The ß2 agonist produced a slow and progressive rise in tremor size that was almost exactly mirrored by a slow and progressive decrease in plasma K+. Conclusions: Ischaemic reduction of postural tremor has been attributed to effects on muscle spindles or an unexplained effect on muscle. This study showed that ischaemia did not reduce tremor size unless there was accompanying muscular activity. An accumulation of K+ in the interstitium of the ischaemic active muscle may blunt the response of the muscle and reduce its fusion frequency, so that the force output becomes less pulsatile and tremor size decreases. When a ß2 agonist is infused, the rise in tremor mirrors the resultant decrease in plasma K+. Decreased plasma K+ reduces interstitial K+ concentration and may produce greater muscular force fluctuation (more tremor). Many other factors that affect postural tremor size may exert their effect by altering plasma K+ concentration, thereby changing the concentration of K+ in the interstitial fluid. PMID:15201362

Previous investigation suggests that visually detected interstitial changes in the lung parenchyma of smokers are highly clinically relevant and predict outcomes, including death. Visual subjective analysis to detect these changes is time-consuming, insensitive to subtle changes, and requires training to enhance reproducibility. Objective detection of such changes could provide a method of disease identification without these limitations. The goal of this study was to develop and test a fully automated image processing tool to objectively identify radiographic features associated with interstitial abnormalities in the computed tomography scans of a large cohort of smokers. An automated tool that uses local histogram analysis combined with distance from the pleural surface was used to detect radiographic features consistent with interstitial lung abnormalities in computed tomography scans from 2257 individuals from the Genetic Epidemiology of COPD study, a longitudinal observational study of smokers. The sensitivity and specificity of this tool was determined based on its ability to detect the visually identified presence of these abnormalities. The tool had a sensitivity of 87.8% and a specificity of 57.5% for the detection of interstitial lung abnormalities, with a c-statistic of 0.82, and was 100% sensitive and 56.7% specific for the detection of the visual subtype of interstitial abnormalities called fibrotic parenchymal abnormalities, with a c-statistic of 0.89. In smokers, a fully automated image processing tool is able to identify those individuals who have interstitial lung abnormalities with moderate sensitivity and specificity.

Pradaxa-induced esophageal ulcer.

PubMed

Wood, Michele; Shaw, Paul

2015-10-09

Pradaxa (dabigatran) is a direct thrombin inhibitor approved for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. We describe a case of esophageal ulceration associated with Pradaxa administration in a 75-year-old man. The patient reported difficulty swallowing and a burning sensation after taking his first dose of Pradaxa. An esophagogastroduodenoscopy (EGD) revealed linear ulcerations in the mid-esophagus. Pradaxa was held beginning the day before the EGD. The patient reported that his pain and difficulty swallowing resolved on stopping Pradaxa. Pradaxa is formulated with a tartaric acid excipient to reduce variability in absorption. We hypothesise that the capsule lodged in the patient's esophagus and the tartaric acid may have caused local damage resulting in an esophageal ulcer. It is important to educate patients on proper administration of Pradaxa, to decrease the risk of this rare, but potentially serious adverse event. 2015 BMJ Publishing Group Ltd.

This paper discusses the critical determinants of pressure ulcer development and proposes a new pressure ulcer conceptual framework. Recent work to develop and validate a new evidence-based pressure ulcer risk assessment framework was undertaken. This formed part of a Pressure UlceR Programme Of reSEarch (RP-PG-0407-10056), funded by the National Institute for Health Research. The foundation for the risk assessment component incorporated a systematic review and a consensus study that highlighted the need to propose a new conceptual framework. Discussion Paper. The new conceptual framework links evidence from biomechanical, physiological and epidemiological evidence, through use of data from a systematic review (search conducted March 2010), a consensus study (conducted December 2010-2011) and an international expert group meeting (conducted December 2011). A new pressure ulcer conceptual framework incorporating key physiological and biomechanical components and their impact on internal strains, stresses and damage thresholds is proposed. Direct and key indirect causal factors suggested in a theoretical causal pathway are mapped to the physiological and biomechanical components of the framework. The new proposed conceptual framework provides the basis for understanding the critical determinants of pressure ulcer development and has the potential to influence risk assessment guidance and practice. It could also be used to underpin future research to explore the role of individual risk factors conceptually and operationally. By integrating existing knowledge from epidemiological, physiological and biomechanical evidence, a theoretical causal pathway and new conceptual framework are proposed with potential implications for practice and research. © 2014 The Authors.

Impact of Facial Conformation on Canine Health: Corneal Ulceration

Packer, Rowena M. A.; Hendricks, Anke; Burn, Charlotte C.

2015-01-01

Concern has arisen in recent years that selection for extreme facial morphology in the domestic dog may be leading to an increased frequency of eye disorders. Corneal ulcers are a common and painful eye problem in domestic dogs that can lead to scarring and/or perforation of the cornea, potentially causing blindness. Exaggerated juvenile-like craniofacial conformations and wide eyes have been suspected as risk factors for corneal ulceration. This study aimed to quantify the relationship between corneal ulceration risk and conformational factors including relative eyelid aperture width, brachycephalic (short-muzzled) skull shape, the presence of a nasal fold (wrinkle), and exposed eye-white. A 14 month cross-sectional study of dogs entering a large UK based small animal referral hospital for both corneal ulcers and unrelated disorders was carried out. Dogs were classed as affected if they were diagnosed with a corneal ulcer using fluorescein dye while at the hospital (whether referred for this disorder or not), or if a previous diagnosis of corneal ulcer(s) was documented in the dogs’ histories. Of 700 dogs recruited, measured and clinically examined, 31 were affected by corneal ulcers. Most cases were male (71%), small breed dogs (mean± SE weight: 11.4±1.1 kg), with the most commonly diagnosed breed being the Pug. Dogs with nasal folds were nearly five times more likely to be affected by corneal ulcers than those without, and brachycephalic dogs (craniofacial ratio <0.5) were twenty times more likely to be affected than non-brachycephalic dogs. A 10% increase in relative eyelid aperture width more than tripled the ulcer risk. Exposed eye-white was associated with a nearly three times increased risk. The results demonstrate that artificially selecting for these facial characteristics greatly heightens the risk of corneal ulcers, and such selection should thus be discouraged to improve canine welfare.

Pressure ulcers are costly and life-threatening complications for people with spinal cord injury (SCI). People with SCI also exhibit differential blood flow properties in non-ulcerated skin. We hypothesized that a computer simulation of the pressure ulcer formation process, informed by data regarding skin blood flow and reactive hyperemia in response to pressure, could provide insights into the pathogenesis and effective treatment of post-SCI pressure ulcers. Agent-Based Models (ABM) are useful in settings such as pressure ulcers, in which spatial realism is important. Ordinary Differential Equation-based (ODE) models are useful when modeling physiological phenomena such as reactive hyperemia. Accordingly, we constructed a hybrid model that combines ODEs related to blood flow along with an ABM of skin injury, inflammation, and ulcer formation. The relationship between pressure and the course of ulcer formation, as well as several other important characteristic patterns of pressure ulcer formation, was demonstrated in this model. The ODE portion of this model was calibrated to data related to blood flow following experimental pressure responses in non-injured human subjects or to data from people with SCI. This model predicted a higher propensity to form ulcers in response to pressure in people with SCI vs. non-injured control subjects, and thus may serve as novel diagnostic platform for post-SCI ulcer formation.

Herein, we report a case that CMV gastric ulcer complicated with pyloric obstruction in a patient with ulcerative colitis during ganciclovir therapy, which was resolved by surgical gastrojejunostomy with review of literature.

Nurses' knowledge of pressure ulcer management in elderly people.

Wilkes, L M; Bostock, E; Lovitt, L; Dennis, G

The nursing management of pressure ulcers has not been extensively reported in the Hong Kong context. This article reports the results of a survey of 34 Hong Kong registered nurses to determine their knowledge and practices in preventing and treating pressure ulcers in the elderly. The findings indicate that, overall, the nurses had a sound knowledge of the prevention and treatment of pressure ulcers, but that there were inconsistencies in their practices. This situation could be improved if standardized systems for assessing patients at risk of developing pressure ulcers and for grading (staging) these pressure ulcers were used.

We present a unique case of duodeno-duodenal intussusception from a duodenal bulb ulcer. A 38-year-old man presented with nausea, vomiting, and abdominal pain. Computed tomography showed duodenal intussusception. Esophagogastroduodenoscopy (EGD) showed a linear gastric ulcer and a duodenal bulb ulcer with an overlying blood clot. Helicobacter pylori status was positive. Intussusception resolved spontaneously without intervention. He completed treatment for H. pylori infection, and repeat EGD showed ulcer healing. Duodenal intussusception is rarely reported; intussusception from an edematous duodenal ulcer with an overlying blood clot mimicking a mass lesion acting as lead point has never been reported to our knowledge.

Peptic ulcer bleeding can be fatal. Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immunosuppressive agents are administered for long-term usage. The present study assessed the association between peptic ulcer bleeding and administration of NSAIDs, corticosteroids and immunosuppressive agents. Furthermore, the efficacy of lowering the risk of peptic ulcer bleeding with proton pump inhibitors (PPI) and histamine 2 receptor antagonists (H2RA) was evaluated. Medical records were retrospectively analyzed for patients subjected to an upper gastrointestinal (GI) endoscopy performed at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) from October 2014 to September 2015. During this period, a total of 1,023 patients underwent an upper GI endoscopy. A total of 1,023 patients, including 431 males (age, 68.1±12.9 years) and 592 females (age, 66.4±12.3 years), who had been administered NSAIDs, corticosteroids, immunosuppressive agents, PPIs and H2RAs, were respectively enrolled. Endoscopic findings of the patients were reviewed and their data were statistically analyzed. Logistic regression analysis was used to determine the odds ratio of peptic ulcer bleeding for each medication; immunosuppressive agents had an odds ratio of 5.83, which was larger than that for NSAIDs (4.77). The Wald test was applied to confirm the correlation between immunosuppressive agents and peptic ulcer bleeding. Furthermore, χ 2 tests were applied to the correlation between peptic ulcer bleeding and administration of PPIs or H2RAs. Immunosuppressive agents had the largest χ 2 , and the P-value was 0.03. Administration of PPIs was significantly correlated with non-peptic ulcer bleeding (P=0.02); furthermore, a tendency toward non-peptic ulcer bleeding with administration of H2RA was indicated, but it was not statistically significant (P=0.12). In conclusion, immunosuppressive agents were correlated with peptic ulcer bleeding and PPIs were effective at

Peptic ulcer bleeding can be fatal. Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immunosuppressive agents are administered for long-term usage. The present study assessed the association between peptic ulcer bleeding and administration of NSAIDs, corticosteroids and immunosuppressive agents. Furthermore, the efficacy of lowering the risk of peptic ulcer bleeding with proton pump inhibitors (PPI) and histamine 2 receptor antagonists (H2RA) was evaluated. Medical records were retrospectively analyzed for patients subjected to an upper gastrointestinal (GI) endoscopy performed at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) from October 2014 to September 2015. During this period, a total of 1,023 patients underwent an upper GI endoscopy. A total of 1,023 patients, including 431 males (age, 68.1±12.9 years) and 592 females (age, 66.4±12.3 years), who had been administered NSAIDs, corticosteroids, immunosuppressive agents, PPIs and H2RAs, were respectively enrolled. Endoscopic findings of the patients were reviewed and their data were statistically analyzed. Logistic regression analysis was used to determine the odds ratio of peptic ulcer bleeding for each medication; immunosuppressive agents had an odds ratio of 5.83, which was larger than that for NSAIDs (4.77). The Wald test was applied to confirm the correlation between immunosuppressive agents and peptic ulcer bleeding.

Objective NOD-like receptors (NLRs) sense sterile and non-sterile signals and form inflammasomes which trigger an inflammatory response through the activation of caspase-1 and release of IL-1β. Recently we have shown the presence of several NLRs in the bladder urothelia and demonstrated the importance of NLRP3 in bladder outlet obstruction and cyclophosphamide-induced cystitis, both models of sterile inflammation. In this study we explore a role for NLRP3 in mediating the response to LPS, a key antigen of uropathogenic bacteria. Method In order to bypass the protective glycosaminoglycan layer lining the urothelium, LPS was directly injected into the bladder wall of Sprague-Dawley rats. Glyburide (a NLRP3 inhibitor) or vehicle was administered orally prior to and after injection. Rats were analyzed 24 h later. Inflammasome activity (caspase-1 activity, IL-1β release) and inflammation (Evan’s Blue extravasation, bladder weight) were assessed, as was physiological bladder function (urodynamics). Results Injection of LPS stimulated inflammasome activation (caspase-1 activity) and the release of IL-1β into the urine which was prevented by glyburide. Likewise, LPS increased inflammation, (bladder weight and the extravasation of Evan’s blue dye), and this was reversed by glyburide. Functionally, animals injected with saline alone demonstrated decreased voiding volume as measured by urodynamics. In the presence of LPS, additional urinary dysfunction was evident with decreased voiding pressures and threshold pressures. The decrease in voiding pressure was blocked by glyburide but the decrease in threshold pressure was not, suggesting that LPS has significant effects mediated by inflammasome-dependent and -independent mechanisms. Conclusion Overall, the results demonstrate the potential importance of inflammasomes in bacterial cystitis as well as the ability of the bladder wall injection technique to isolate the in vivo effects of specific inflammasome ligands to the

Diffusionless displacive lattice rearrangements, which include martensitic transformations, are in real materials often accompanied by a displacive drag of interstitials. The interplay of both processes leads to a particular atomistic arrangement of the interstitials in the product phase, which is decisive for its performance. An archetype example is the martensitic transformation in Fe-C alloys. One of the puzzles for this system is that the deviation from the cubic symmetry (i.e., the tetragonality) in the martensite resulting from this interplay is lower than what thermodynamics dictates. In our ab initio approach, the relative motion of C in the transforming lattice is studied with the nudged elastic band method. We prove that an atomic shearlike shuffle mechanism of adjacent (11 2 ¯) Fe layers along the ±[111] bcc directions is essential to achieve a redistribution of C atoms during the fcc → bcc transition, which fully explains the abnormal behavior. Furthermore, the good agreement with experiment validates our method to treat a diffusionless redistribution of interstitials and a displacive rearrangement of the host lattice simultaneously.

Healing of venous leg ulcers is improved by the use of compression bandaging but some venous ulcers remain unhealed, and some people are unsuitable for compression therapy. Pentoxifylline, a drug which helps blood flow, has been used to treat venous leg ulcers. To assess the effects of pentoxifylline (oxpentifylline or Trental 400) for treating venous leg ulcers, compared with a placebo or other therapies, in the presence or absence of compression therapy. For this fifth update we searched the Cochrane Wounds Group Specialised Register (searched 20 July 2012); The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 7); Ovid MEDLINE (2010 to July Week 2 2012); Ovid MEDLINE (In-Process & Other Non-Indexed Citations, July 19, 2012); Ovid EMBASE (2010 to 2012 Week 28); and EBSCO CINAHL (2010 to July 13 2012). Randomised trials comparing pentoxifylline with placebo or other therapy in the presence or absence of compression, in people with venous leg ulcers. One review author extracted and summarised details from eligible trials using a coding sheet. One other review author independently verified data extraction. No new trials were identified for this update. We included twelve trials involving 864 participants. The quality of trials was variable. Eleven trials compared pentoxifylline with placebo or no treatment. Pentoxifylline is more effective than placebo in terms of complete ulcer healing or significant improvement (RR 1.70, 95% CI 1.30 to 2.24). Pentoxifylline plus compression is more effective than placebo plus compression (RR 1.56, 95% CI 1.14 to 2.13). Pentoxifylline in the absence of compression appears to be more effective than placebo or no treatment (RR 2.25, 95% CI 1.49 to 3.39).More adverse effects were reported in people receiving pentoxifylline (RR 1.56, 95% CI 1.10 to 2.22). Nearly three-quarters (72%) of the reported adverse effects were gastrointestinal. Pentoxifylline is an effective adjunct to compression

The Japanese Society of Gastroenterology (JSGE) revised the evidence-based clinical practice guidelines for peptic ulcer disease in 2014 and has created an English version. The revised guidelines consist of seven items: bleeding gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcer, non-H. pylori, non-nonsteroidal anti-inflammatory drug (NSAID) ulcer, surgical treatment, and conservative therapy for perforation and stenosis. Ninety clinical questions (CQs) were developed, and a literature search was performed for the CQs using the Medline, Cochrane, and Igaku Chuo Zasshi databases between 1983 and June 2012. The guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Therapy is initially provided for ulcer complications. Perforation or stenosis is treated with surgery or conservatively. Ulcer bleeding is first treated by endoscopic hemostasis. If it fails, surgery or interventional radiology is chosen. Second, medical therapy is provided. In cases of NSAID-related ulcers, use of NSAIDs is stopped, and anti-ulcer therapy is provided. If NSAID use must continue, the ulcer is treated with a proton pump inhibitor (PPI) or prostaglandin analog. In cases with no NSAID use, H. pylori-positive patients receive eradication and anti-ulcer therapy. If first-line eradication therapy fails, second-line therapy is given. In cases of non-H. pylori, non-NSAID ulcers or H. pylori-positive patients with no indication for eradication therapy, non-eradication therapy is provided. The first choice is PPI therapy, and the second choice is histamine 2-receptor antagonist therapy. After initial therapy, maintenance therapy is provided to prevent ulcer relapse.

BACKGROUND: Among the chronic leg ulcers, venous ulcers are the most common and constitute a major burden to public health. Despite all technology available, some patients do not respond to established treatments. In our study, carboxymethylcellulose was tested in the treatment of refractory chronic venous ulcers. OBJECTIVE: To evaluate the efficacy of carboxymethylcellulose 20% on the healing of chronic venous ulcers refractory to conventional treatments. METHODS: This is an analytical, pre-experimental study. Thirty patients were included with refractory venous ulcers, and applied dressings with carboxymethylcellulose 20% for 20 weeks. The analysis was based on measurement of the area of ulcers, performed at the first visit and after the end of the treatment. RESULTS: There was a reduction of 3.9 cm2 of lesion area (p=0.0001), corresponding to 38.8% (p=0.0001). There was no interruption of treatment and no increase in lesion area in any patient. CONCLUSIONS: Carboxymethylcellulose 20% represents a low cost and effective therapeutic alternative for the treatment of refractory chronic venous ulcers. However, controlled studies are necessary to prove its efficacy. PMID:26982773

Objectives We aimed at determining peptic ulcer disease (PUD) incidence among chronic kidney disease (CKD) patients during 1998–2008, compared to patients without CKD, and at examining associations between CKD and PUD. Methods Data for 1998–2008 were extracted from the National Health Insurance Research Database in Taiwan. The annual PUD incidence (cases per thousand persons per year) was calculated separately for patients with and without CKD. Characteristics of patients with newly diagnosed PUD (n = 16322) were compared to those of a control group without PUD (n = 32644). The 2 groups were matched for age, sex, and index year. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Results Over the 10-year period, the PUD incidence was ∼10–12 times higher in CKD patients than in those without CKD. Its incidence in elderly CKD patients increased rapidly over time. For CKD patients, most PUD events (>95%) were managed during hospitalization. Peptic ulcer risk, adjusted for all potential confounders, was much higher in CKD patients undergoing hemodialysis (adjusted OR, 9.74; 95% CI, 7.11–13.31). Maintenance hemodialysis patients were 2 times more likely to have gastric ulcers than duodenal ulcers, while CKD patients not on dialysis had similar risks for both. There were no significant interactions between medications and CKD status on the peptic ulcer risk. Unlike CKD patients on nonsteroidal anti-inflammatory drugs and clopidogrel, those on aspirin did not have a higher peptic ulcer risk (adjusted OR, 0.88; 95% CI, 0.44–1.77). Conclusions CKD patients have a substantially increased PUD risk, and the majority of CKD patients with PUD require hospital management. Further, peptic ulcer risk is affected by hemodialysis therapy, patient status (inpatient vs. outpatient), and ulcerogenic medications. PMID:24498412

Geographic and temporal variations in the occurrence of peptic ulcer disease.

The epidemiology of peptic ulcer is characterised by marked geographic and temporal variations. Gastric ulcer occurs about 5-10 times more often than duodenal ulcer in Japan. In most European countries and the USA, duodenal ulcer is about twice as frequent as gastric ulcer. The variation among different European countries does not show any clear-cut relationship to European geography. The reported differences in healing rate, relapse rate after discontinuation of treatment with histamine2 (H2)-blockers, and harmful effects of smoking are probably related to the varying fraction of bad healers recruited for controlled clinical trials in different countries. In male migrant workers who emigrated from Southern to Central Europe, duodenal ulcer occurs twice as frequent as in the native population. A similar phenomenon has been reported from South Africa. Peptic ulcer used to be a rare disease before the 19th century. In the beginning of the 19th century acute perforations of gastric ulcers were first reported in young girls. With progress of the 19th century peptic ulcer became more frequent also in men. By the end of the century the incidence of duodenal ulcer had surpassed that of gastric ulcer. Studies from the USA and England reported that the number of hospital admissions, surgical operations, and deaths due to duodenal or gastric ulcer had declined during the last 20 years. A cohort analysis demonstrates that the temporal changes of peptic ulcer in all European countries, in Japan, and in the USA occur in a fashion characteristic of those due to changes in birth-cohort risks. Generations born in the last 30 years of the 19th century manifested the highest risk of developing peptic ulcer and carried it throughout their lives. The birth-cohorts with a high risk for duodenal ulcer lagged 10-30 years behind those with a high risk for gastric ulcer. The cohort phenomenon starts at an age below 5 years for both gastric and duodenal ulcer. The cohort phenomenon implies
