    Although there is a strong biological rationale to electively treat the pelvic nodes during bladder preservation, its clinical benefit is uncertain. This may be explained by the incidental dose received by the nodal regions when treating the bladder alone. This study was conducted to investigate the doses received by the different pelvic nodal regions when the bladder alone is treated by standard conformal radiotherapy. The computed tomography data sets of 20 patients with node-negative muscle-invasive bladder cancer treated in a bladder preservation protocol were studied. Patients were originally treated with conformal radiotherapy to the bladder alone. Replanning was done with additional delineation of the pelvic nodal regions namely common iliac (upper and lower), presacral, internal iliac, obturator, and external iliac. Dose volume parameters such as Dmean, Dmax, D100%, D66%, D33%, V40, and V50 to each of the nodal regions were estimated for all patients. The obturator nodes received the highest dose among all nodal regions. The mean dose received by obturator, external iliac, and internal iliac regions was 59, 45, and 36 Gy, respectively. The dose received by these 3 regions in the full bladder state was 63, 52, and 47 Gy, respectively. The dose received by all other pelvic nodal regions was low and not clinically relevant. The incidental dose received by obturator and external iliac nodes is clinically significant in bladder-only radiation, possibly enough to influence micrometastatic disease. This may be a reason for the lack of clear benefit seen with nodal irradiation in bladder cancer. Advances in Knowledge: This study highlights that the incidental dose received by obturator and external iliac nodes is clinically significant in bladder-only radiation. The obturator nodes received the highest dose among all nodal regions with mean dose of 59 Gy.

    Full Text Available The incidence of obesity has increased dramatically during recent decades. Obesity increases the risk for metabolic and cardiovascular diseases and may therefore contribute to premature death. With increasing fat mass, secretion of adipose tissue derived bioactive molecules (adipokines changes towards a pro-inflammatory, diabetogenic and atherogenic pattern. Adipokines are involved in the regulation of appetite and satiety, energy expenditure, activity, endothelial function, hemostasis, blood pressure, insulin sensitivity, energy metabolism in insulin sensitive tissues, adipogenesis, fat distribution and insulin secretion in pancreatic β-cells. Therefore, adipokines are clinically relevant as biomarkers for fat distribution, adipose tissue function, liver fat content, insulin sensitivity, chronic inflammation and have the potential for future pharmacological treatment strategies for obesity and its related diseases. This review focuses on the clinical relevance of selected adipokines as markers or predictors of obesity related diseases and as potential therapeutic tools or targets in metabolic and cardiovascular diseases.

    Diagnosis of pelvic inflammatory disease is difficult. We focus on a systematic literature review to study diagnostic values of history-taking, clinical examination, laboratory tests and imagery. After this literature review, we build a diagnostic model for pelvic inflammatory disease. This diagnostic model is built on two major criteria: presence of adnexal tenderness or cervical motion tenderness. Additional minor criteria, increasing the likelihood of the diagnosis of pelvic inflammatory disease were added based on their specificity and their positive likelihood ratio. These minor criteria are supported by history-taking, clinical examination, laboratory tests and also on relevant ultrasonographic criteria. Copyright © 2012 Elsevier Masson SAS.

    We aimed to develop a questionnaire that assesses the impact of pelvic pain on women, regardless of diagnosis, that has high utility, sound psychometric performance, easy scoring, and high reliability. Two studies, with 3 separate cohorts, were undertaken. Both studies were completed online. Studies included women with self-reported pelvic pain. Women were eligible to participate regardless of whether their pelvic pain was undiagnosed, self-diagnosed, or diagnosed by a clinician. Study 1 used a 3-round "patient-as-expert" Delphi technique. These rounds defined the 10 aspects of life with the self-reported greatest impact on the lives of women with pelvic pain, which formed the questionnaire. Study 2 used Rasch analysis to assess the psychometric properties of the resultant 10-item questionnaire. To assess its reliability, a subgroup completed the questionnaire 3 times over a 3-week period. In study 1, 443 women with pelvic pain participated. The resultant 10-item questionnaire consisted of 8 Likert questions and 2 supplemental, nonscored questions. In study 2, 1203 women with pelvic pain completed the questionnaire. Rasch analysis showed that the questionnaire targeted the pelvic pain population well, had appropriate Likert categories, constituted a unidimensional scale, and showed internal consistency. Twenty-seven women with pelvic pain completed the reliability trial. Test-retest reliability was high (intraclass correlation coefficient 0.91, P Pelvic Pain Impact Questionnaire assesses the life impact of pelvic pain. It uses patient-generated language, is easily administered and scored, has very strong psychometric properties, and it is suitable for research and clinical settings across primary, secondary, and tertiary care.

    Usually, in clinical practice the maneuver selected is the one that achieves a favorable outcome with a direct percentage of superiority of at least 10 %, or when the number needed to treat is approximately equal to 10. While this percentage difference is practical for estimating the magnitude of an association, we need to differentiate the impact measures (attributable risk, preventable fraction), measures of association (RR, OR, HR), and frequency measures (incidence and prevalence) applicable when the outcome is nominal. And we must identify ways to measure the strength of association and the magnitude of the association when the outcome variable is quantitative. It is not uncommon to interpret the measures of association as if they were impact measures. For example, for a RR of 0.68, it is common to assume a 32 % reduction of the outcome, but we must consider that this is a relative reduction, which comes from relations of 0.4/0.6, 0.04/0.06, or 0.00004/0.00006. However the direct reduction is 20 % (60 % - 40 %), 2 %, and 2 per 100,000, respectively. Therefore, to estimate the impact of a maneuver it is important to have the direct difference and/or NNT.

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

    In March this year, the American Statistical Association (ASA) posted a statement on the correct use of P-values, in response to a growing concern that the P-value is commonly misused and misinterpreted. We aim to translate these warnings given by the ASA into a language more easily understood by clinicians and researchers without a deep background in statistics. Moreover, we intend to illustrate the limitations of P-values, even when used and interpreted correctly, and bring more attention to the clinical relevance of study findings using two recently reported studies as examples. We argue that P-values are often misinterpreted. A common mistake is saying that P < 0.05 means that the null hypothesis is false, and P ≥0.05 means that the null hypothesis is true. The correct interpretation of a P-value of 0.05 is that if the null hypothesis were indeed true, a similar or more extreme result would occur 5% of the times upon repeating the study in a similar sample. In other words, the P-value informs about the likelihood of the data given the null hypothesis and not the other way around. A possible alternative related to the P-value is the confidence interval (CI). It provides more information on the magnitude of an effect and the imprecision with which that effect was estimated. However, there is no magic bullet to replace P-values and stop erroneous interpretation of scientific results. Scientists and readers alike should make themselves familiar with the correct, nuanced interpretation of statistical tests, P-values and CIs. © The Author 2017.

    Chlamydia infection in acute pelvic inflammatory disease (PID) is associated with serious complications including ectopic pregnancy, tubal infertility, Fitz-Hugh-Curtis syndrome and tubo-ovarian abscess (TOA). This study compared clinical and laboratory data between PID with and without chlamydia infection. The medical records of 497 women who were admitted with PID between 2002 and 2011 were reviewed. The patients were divided into two groups (PID with and without chlamydia infection), which were compared in terms of the patients' characteristics, clinical presentation, and laboratory findings, including inflammatory markers. The chlamydia and non-chlamydia groups comprised 175 and 322 women, respectively. The patients in the chlamydia group were younger and had a higher rate of TOA, a longer mean hospital stay, and had undergone more surgeries than the patients in the non- chlamydia group. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and CA-125 level were higher in the chlamydia group than in the non-chlamydia group, but there was no significant difference in the white blood cell count between the two groups. The CA-125 level was the strongest predictor of chlamydia infection, followed by the ESR and CRP level. The area under the receiving operating curve for CA-125, ESR, and CRP was 0.804, 0.755, and 0.663, respectively. Chlamydia infection in acute PID is associated with increased level of inflammatory markers, such as CA-125, ESR and CRP, incidence of TOA, operation risk, and longer hospitalization.

    Overactive bladder (OAB) and bladder pain syndrome (BPS) although common, are vaguely defined and difficult to diagnose and manage etiologies of storage-type lower urinary tract symptoms (LUTS). The lack of optimal management options is a direct consequence of deficient understanding of the pathophysiologic mechanisms underlying these conditions. These conditions are especially prevalent in females, and cumulative contemporary epidemiological, clinical and laboratory evidence implicates ischemia as one of the key players in the pathophysiologic foundation of both these disorders. Taken together they make up "the" diagnostic as well as therapeutic black-hole in urologic practice. Much akin to chronic ischemic heart disease, chronic ischemia-reperfusion has been shown to cause degenerative changes at cellular and subcellular level in the bladder mucosa, smooth muscle fibers, and vesical neural and microvascular structures leading to a hypersensitive, hyperactive bladder initially, which with time invariably progresses into a failed, fibrotic and pressurized bladder. Diagnosis and management of these diseases are currently symptom focused and remains a source of much frustration. Consideration of role of ischemia connotates hope and could lead to a paradigm shift in the management of these patients with a completely new therapeutic armamentarium attacking the pathology itself. The aim of the current review is to provide a clinical thought perspective on the etiology/pathophysiology of chronic pelvic ischemia and its role as a precursor to the aforementioned conditions, and shed some light upon the potential management strategies to consider.

  17. Valerian: No Evidence for Clinically Relevant Interactions

    2014-01-01

    Full Text Available In recent popular publications as well as in widely used information websites directed to cancer patients, valerian is claimed to have a potential of adverse interactions with anticancer drugs. This questions its use as a safe replacement for, for example, benzodiazepines. A review on the interaction potential of preparations from valerian root (Valeriana officinalis L. root was therefore conducted. A data base search and search in a clinical drug interaction data base were conducted. Thereafter, a systematic assessment of publications was performed. Seven in vitro studies on six CYP 450 isoenzymes, on p-glycoprotein, and on two UGT isoenzymes were identified. However, the methodological assessment of these studies did not support their suitability for the prediction of clinically relevant interactions. In addition, clinical studies on various valerian preparations did not reveal any relevant interaction potential concerning CYP 1A2, 2D6, 2E1, and 3A4. Available animal and human pharmacodynamic studies did not verify any interaction potential. The interaction potential of valerian preparations therefore seems to be low and thereby without clinical relevance. We conclude that there is no specific evidence questioning their safety, also in cancer patients.

    PurposeTo describe and categorize the angiographic findings regarding prostatic vascularization, propose an anatomic classification, and discuss its implications for the PAE procedure.MethodsAngiographic findings from 143 PAE procedures were reviewed retrospectively, and the origin of the inferior vesical artery (IVA) was classified into five subtypes as follows: type I: IVA originating from the anterior division of the internal iliac artery (IIA), from a common trunk with the superior vesical artery (SVA); type II: IVA originating from the anterior division of the IIA, inferior to the SVA origin; type III: IVA originating from the obturator artery; type IV: IVA originating from the internal pudendal artery; and type V: less common origins of the IVA. Incidences were calculated by percentage.ResultsTwo hundred eighty-six pelvic sides (n = 286) were analyzed, and 267 (93.3 %) were classified into I–IV types. Among them, the most common origin was type IV (n = 89, 31.1 %), followed by type I (n = 82, 28.7 %), type III (n = 54, 18.9 %), and type II (n = 42, 14.7 %). Type V anatomy was seen in 16 cases (5.6 %). Double vascularization, defined as two independent prostatic branches in one pelvic side, was seen in 23 cases (8.0 %).ConclusionsDespite the large number of possible anatomical variations of male pelvis, four main patterns corresponded to almost 95 % of the cases. Evaluation of anatomy in a systematic fashion, following a standard classification, will make PAE a faster, safer, and more effective procedure.

  20. Surgical Stabilization of Pelvic and Acetabular Fractures: A Review on the Determinants of Clinical Outcomes

    Directory of Open Access Journals (Sweden)

    SS Sathappan

    2010-03-01

    Full Text Available AIM: Pelvic and acetabular fractures are associated with high-energy trauma. The aim of this study was to identify factors that are associated with specific clinical outcomes following treatment for these fractures. METHODS: A consecutive series of 30 patients who had surgical intervention for either pelvic or acetabular fractures formed the sample for this study. Clinical variables reviewed were: age, associated injuries, number of surgical procedures, time to surgery and post-operative complications. Clinical outcomes were assessed using Matta’s grading of post- operative fracture reduction alignment, and functional outcomes were graded using D'Aubigne & Postel’s Hip scoring system. RESULTS: Study subjects included twelve pelvic fractures and eighteen acetabular fractures. Patients older than 50 years of age had poorer hip scores despite surgery. Earlier fracture fixation (within five days was associated with better hip scores. Patients with acetabular fractures generally had better functional outcomes than patients with pelvic fractures (mean hip score 15.0 vs. 13.5. Closer anatomical reduction of acetabular fractures was associated with better functional outcome. CONCLUSION: Improved clinical outcomes are associated with younger age, fewer concomitant injuries, shorter time interval to surgery and more closely approximated anatomical fracture reduction.

    The purpose of this paper is to clarify the clinical significance of CT in the diagnosis of severe pelvic fractures. Fifty-six consecutive patients with severe pelvic ring fractures were the subjects of this study. The assessments were as follows: comparison of the diagnostic value of plain X-P and CT for the detection of pelvic fractures, comparison hemodynamic findings before TAE therapy, comparison between abnormal angiographic findings and fracture sites on CT, and comparison between abnormal angiographic findings and volume of retroperitoneal hematomas on CT. CT was more useful for the detection of severe pelvic ring fractures, especially for sacral fracture and iliosacral joint dislocations, than plain X-P. Sacral fracture group was more severe than iliac fracture group on CT. There was a discrepancy between the angiographic findings and fracture sites in 20 of the 56 patients. Angiographic abnormalities without fracture were seen especially in the lateral sacral artery and iliolumbar artery. There was a discrepancy between the angiographic findings and retroperitoneal hematomas in 38 of the 56 patients. Retroperitoneal hematomas, especially around the ilium, were seen on CT in 40 areas in the absence of any abnormal angiographic findings. Conversely, angiographic extravasation without hematoma on CT was seen in 20 areas, especially in lateral sacral artery. CT is useful for detection and intervention in severe pelvic ring fractures.

    Embryology finds itself jostling for precious space in the crowded medical curriculum, yet remains important for helping students understand birth defects. It has been suggested that teaching embryology through clinical scenarios can increase its relevance and interest. The aim of this research was to determine the attitudes of final-year medical students to learning embryology and whether clinical scenarios aid understanding. Final-year medical students undertaking their paediatric rotation in 2009 and 2010 were invited to attend an optional lecture on clinical embryology and participate in the research. In the lecture, three clinical scenarios were presented, in which the lecturer traced the normal development of a foetus and the abnormal development that resulted in a birth defect. Outcomes were assessed quantitatively using a paper-based survey. The vast majority of students who valued embryology teaching in their medical programme thought it would assist them with clinical management, and believed learning through case scenarios helped their understanding. Students were divided in their beliefs about when embryology should be taught in the medical programme and whether it would increase their workload. Embryology teaching appears to be a valuable part of the medical curriculum. Embryology teaching was valued when taught in the clinical environment in later years of the medical programme. Students, clinicians and medical educators should be proactive in finding clinical learning opportunities for embryology teaching. © 2013 Royal Australasian College of Surgeons.

    Pelvic inflammatory disease (PID) is a common medical problem, with almost 1 million cases diagnosed annually. Historically, PID has been a clinical diagnosis supplemented with the findings from ultrasonography (US) or magnetic resonance (MR) imaging. However, the diagnosis of PID can be challenging because the clinical manifestations may mimic those of other pelvic and abdominal processes. Given the nonspecific clinical manifestations, computed tomography (CT) is commonly the first imaging examination performed. General CT findings of early- and late-stage PID include thickening of the uterosacral ligaments, pelvic fat stranding with obscuration of fascial planes, reactive lymphadenopathy, and pelvic free fluid. Recognition of these findings, as well as those seen with cervicitis, endometritis, acute salpingitis, oophoritis, pyosalpinx, hydrosalpinx, tubo-ovarian abscess, and pyometra, is crucial in allowing prompt and accurate diagnosis. Late complications of PID include tubal damage resulting in infertility and ectopic pregnancy, peritonitis caused by uterine and/or tubo-ovarian abscess rupture, development of peritoneal adhesions resulting in bowel obstruction and/or hydroureteronephrosis, right upper abdominal inflammation (Fitz-Hugh-Curtis syndrome), and septic thrombophlebitis. Recognition of these late manifestations at CT can also aid in proper patient management. At CT, careful assessment of common PID mimics, such as endometriosis, adnexal torsion, ruptured hemorrhagic ovarian cyst, adnexal neoplasms, appendicitis, and diverticulitis, is important to avoid misinterpretation, delay in management, and unnecessary surgery. Correlation with the findings from complementary imaging examinations, such as US and MR imaging, is useful for establishing a definitive diagnosis. (©)RSNA, 2016.

    The baroreflex, chemoreflex, pulmonary reflexes, Bezold-Jarisch and Bainbridge reflexes and their interaction with local mechanisms, are a demonstration of the richness of cardiovascular responses that occur in human beings. As well as these, the anesthesiologist must contend with other variables that interact by attenuating or accentuating cardiopulmonary reflexes such as, anesthetic drugs, surgical manipulation, and patient positioning. In the present article we review these reflexes and their clinical relevance in anesthesiology. Copyright © 2012 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

    Women with epilepsy (WWE) face specific challenges throughout their lifespan due to the effects of seizures and antiepileptic drugs on hormonal function, potentially affecting both sexual and reproductive health. This review article addresses the most common issues of practical relevance to clinicians treating WWE: epidemiology and clinical presentations (including catamenial epilepsy), contraception, reproductive and sexual dysfunction, pregnancy, lactation, menopause-related issues (including bone health), and mental health aspects. Awareness of these gender-specific issues and implementation/adaptation of effective interventions for WWE results in significantly improved health-related quality of life in this patient population.

    In forensic anthropology, identification begins by determining the sex, age, ancestry and stature of the individuals. Asymptomatic variations present on the skeleton, known as discrete traits, can be useful to identify individuals, or at least contribute to complete their biological profile. We decided to focus our work on the upper part of the skeleton, from the first vertebra to the pelvic girdle, and we chose to present 8 discrete traits (spina bifida occulta, butterfly vertebra, supraclavicular nerve foramen, coracoclavicular joint, os acromiale, suprascapular foramen, manubrium foramen and pubic spine), because they show a frequency lower than 10%. We examined 502 anonymous CT scans from polytraumatized individuals, aged 15 to 65 years, in order to detect the selected discrete traits. Age and sex were known for each subject. Thin sections in the axial, coronal and sagittal planes and 3D volume rendering images were created and examined for the visualization of the selected discrete traits. Supraclavicular foramina were found only in males and only on the left clavicle. Coracoclavicular joints were observed only in males. The majority of individuals with a suprascapular foramen were older than 50 years of age. Pubic spines were observed mostly in females. Other traits did not present significant association with sex, age and laterality. No association between traits was highlighted. Better knowledge of human skeletal variations will help anthropologists come closer to a positive identification, especially if these variations are rare, therefore making them more discriminant.

    The sacral perineural cyst was first described by Tarlov in 1938 as an incidental finding at autopsy. There are very few data in the literature regarding the role of Tarlov cysts in causing symptoms, however. Most studies report low numbers, and consequently, the recommendations for treatment are vague. Our aim, therefore, is to present further detail regarding the clinical relevance of Tarlov cysts and to identify whether or not they are a cause of lumbosacral spinal canal stenosis symptoms. Over a 5-year period, 3535 patients underwent magnetic resonance imaging (MRI) scan for lumbosacral symptoms. Fifty-four patients were identified as having Tarlov cysts, and their clinical picture was correlated with the findings on MRI. The majority of Tarlov cysts (n = 38) cannot be held responsible for patients' symptoms and are clinically unimportant. However, we encountered several patients in whom Tarlov cysts (n = 9) occurred at the same level as another pathology. In these cases, the cyst itself did not require any specific therapy; treatment was directed at the other pathology, and uneventful symptom resolution occurred. A smaller subgroup of cysts (n = 7) are the main cause of patients' symptoms and may require specific treatment to facilitate local decompression. The majority of Tarlov cysts are incidental findings on MRI. Where confusion exists as to the clinical relevance of a Tarlov cyst, treatment of the primary pathology (ie, non-Tarlov lesion) is usually sufficient. Tarlov cysts may, however, be responsible for a patient's symptoms; possible mechanisms by which this may occur and treatment strategies are discussed.

    2009-01-01

    One of the most exciting events in neurosciences over the past few years has been the discovery of a mechanism that unifies action perception and action execution. The essence of this 'mirror' mechanism is as follows: whenever individuals observe an action being done by someone else, a set of neurons that code for that action is activated in the observers' motor system. Since the observers are aware of the outcome of their motor acts, they also understand what the other individual is doing without the need for intermediate cognitive mediation. In this Review, after discussing the most pertinent data concerning the mirror mechanism, we examine the clinical relevance of this mechanism. We first discuss the relationship between mirror mechanism impairment and some core symptoms of autism. We then outline the theoretical principles of neurorehabilitation strategies based on the mirror mechanism. We conclude by examining the relationship between the mirror mechanism and some features of the environmental dependency syndromes.

  13. Extracellular vesicles: fundamentals and clinical relevance

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available All types of cells of eukaryotic organisms produce and release small nanovesicles into their extracellular environment. Early studies have described these vesicles as ′garbage bags′ only to remove obsolete cellular molecules. Valadi and colleagues, in 2007, were the first to discover the capability of circulating extracellular vesicles (EVs to horizontally transfer functioning gene information between cells. These extracellular vesicles express components responsible for angiogenesis promotion, stromal remodeling, chemoresistance, genetic exchange, and signaling pathway activation through growth factor/receptor transfer. EVs represent an important mode of intercellular communication by serving as vehicles for transfer between cells of membrane and cytosolic proteins, lipids, signaling proteins, and RNAs. They contribute to physiology and pathology, and they have a myriad of potential clinical applications in health and disease. Moreover, vesicles can pass the blood-brain barrier and may perhaps even be considered as naturally occurring liposomes. These cell-derived EVs not only represent a central mediator of the disease microenvironment, but their presence in the peripheral circulation may serve as a surrogate for disease biopsies, enabling real-time diagnosis and disease monitoring. In this review, we′ll be addressing the characteristics of different types of extracellular EVs, as well as their clinical relevance and potential as diagnostic markers, and also define therapeutic options.

    Full Text Available This review presents a generalized definition of vesicles as bilayer extracellular organelles of all celular forms of life: not only eu-, but also prokaryotic. The structure and composition of extracellular vesicles, history of research, nomenclature, their impact on life processes in health and disease are discussed. Moreover, vesicles may be useful as clinical instruments for biomarkers, and they are promising as biotechnological drug. However, many questions in this area are still unresolved and need to be addressed in the future. The most interesting from the point of view of practical health care represents a direction to study the effect of exosomes and microvesicles in the development and progression of a particular disease, the possibility of adjusting the pathological process by means of extracellular vesicles of a particular type, acting as an active ingredient. Relevant is the further elucidation of the role and importance of exosomes to the surrounding cells, tissues and organs at the molecular level, the prospects for the use of non-cellular vesicles as biomarkers of disease.

    Full Text Available Many gynecological and sexological problems (like urine incontinence, chronic pelvic pains, vulvodynia, and lack of lust, excitement, and orgasm are resistant to standard medical treatment. In our work at the Research Clinic for Holistic Medicine in Copenhagen, we have found that vaginal acupressure, or Hippocratic pelvic massage, can help some of these problems. Technically, it is a very simple procedure as it corresponds to the explorative phase of the standard pelvic examination, supplemented with the patient's report on the feelings it provokes and the processing and integration of these feelings. Sometimes it can be very difficult to control the emotions released by the technique, i.e., regression to earlier traumas from childhood sexual abuse. This review discusses the theory behind vaginal acupressure, ethical aspects, and presentation of a case story. This procedure helped the patient to become present in her pelvis and to integrate old traumas with painful emotions. Holistic gynecology and sexology can help the patient to identify and let go of negative feelings, beliefs, and attitudes related to sex, gender, sexual organs, body, and soul at large. Shame, guilt, helplessness, fear, disgust, anxiety, anger, hatred, and other strong feelings are almost always an important part of a sexual or functional problem as these feelings are “held” by the tissue of the pelvis and sexual organs. Acupressure through the vagina/pelvic massage must be done with great care by an experienced physician, with a third person present, after obtaining consent and the necessary trust of the patient. It must be followed by conversational therapy and further holistic existential processing.

    Full Text Available Introduction. Actinomycosis is a chronic bacterial infection caused by Actinomyces, Gram-positive anaerobic bacteria. Its symptomatology imitates some malignant pelvic tumours, tuberculosis, or nocardiosis, causing abscesses and fistulas. Actinomycoses are opportunistic infections and require normal mucous barriers to be altered. No epidemiological studies have been conducted to determine prevalence or incidence of such infections. Objective. To analyse the clinical cases of pelvic actinomycosis reported worldwide, to update the information about the disease. Methods. A systematic review of worldwide pelvic actinomycosis cases between 1980 and 2014 was performed, utilising the PubMed, Scopus, and Google Scholar databases. The following information was analysed: year, country, type of study, number of cases, use of intrauterine device (IUD, final and initial diagnosis, and method of diagnosis. Results. 63 articles met the search criteria, of which 55 reported clinical cases and 8 reported cross-sectional studies. Conclusions. Pelvic actinomycosis is confusing to diagnose and should be considered in the differential diagnosis of pelvic chronic inflammatory lesions. It is commonly diagnosed through a histological report, obtained after a surgery subsequent to an erroneous initial diagnosis. A bacterial culture in anaerobic medium could be useful for the diagnosis but requires a controlled technique and should be performed using specialised equipment.

    Full Text Available Objective. To evaluate the clinical outcomes and urodynamic effects of tailored anterior transvaginal mesh surgery (ATVM and tailored posterior transvaginal mesh surgery (PTVM. Methods. We developed ATVM for the simultaneous correction of cystocele and stress urinary incontinence and PTVM for the simultaneous correction of enterocoele, uterine prolapse, vaginal stump prolapse, and rectocele. Results. A total of 104 women enrolled. The median postsurgical follow-up was 25.5 months. The anatomic cure rate was 98.1% (102/104. Fifty-eight patients underwent urodynamic studies before and after surgeries. The pad weight decreased from 29.3 ± 43.1 to 6.4 ± 20.9 g at 3 months. Among the 20 patients with ATVM, 13 patients had objective stress urinary incontinence (SUI at baseline while 8 patients came to have no demonstrated SUI (NDSUI, and 2 improved after surgery. Among the 38 patients who underwent ATVM and PTVM, 24 had objective SUI at baseline while 18 came to have NDSUI, and 2 improved after surgery. Mesh extrusion (n = 4, vaginal hematoma (n = 3, and voiding difficulty (n = 2 were noted postoperatively. Quality of life was substantially improved. Conclusions. Our findings document the advantages of these two novel pelvic reconstructive surgeries for pelvic organ prolapse, which had a positive impact on quality of life. ATVM surgery additionally provided an anti-incontinence effect. This clinical trial is registered at ClinicalTrials.gov (NCT02178735.

  1. Serumferritin - diagnostic relevance and clinical usefulness

    1984-01-01

    The introduction of a WHO Standard for serumferritin effected a standardisation of different methods, improving quality and security for clinical routine diagnostic purposes. Therefore the clinical evaluation of serumferritin gained even more importance. For evaluation of iron stores of children, pregnant women, population studies, patients on hemodialysis or patients with rheumatoid arthritis low serumferritin values give safe results. In addition serumferritin is of clinical usefulness in monitoring therapy of both iron deficiency and iron overload. Evaluating a single serumferritin value one should consider the total clinical situation of the patient. As some tumors can produce and secrete serumferritin, e.g. acute myeloblastic leukemia, germ cell tumors, malignant melanoma, serumferritin might be helpful in monitoring the malignant disease. The ongoing characterization of tissue isoferritin, especially acidic isoferritin, may eventually lead to a clinically significant diagnostic marker of neoplasia.

Self-evaluated physical and mental health was significantly improved for the total group; the relationship with partner, the subjective sexual ability, and the quality of life that were measured with QOL1 and QOL5 questionnaires were all significantly improved. VA or Hippocratic pelvic massage is technically a simple procedure corresponding to the explorative phase of the standard pelvic examination, supplemented with the patient’s report on the feelings provoked followed by processing and integration of these feelings, but ethical aspects are complicated. Acupressure through the vagina/pelvic massage must be done according to the highest ethical standard with great care, after obtaining consent and the necessary trust of the patient within the framework of the local laws.

    AIM: To determine available information on an independent peptide transporter 1(Pep T1) and its potential relevance to treatment, this evaluation was completed.METHODS: Fully published English language literature articles sourced through Pub Med related to protein digestion and absorption, specifically human peptide and amino acid transport, were accessed and reviewed.Papers from 1970 to the present, with particular emphasis on the past decade, were examined. In addition,abstracted information translated to English in Pub Med was also included. Finally, studies and reviews relevant to nutrient or drug uptake, particularly in human intestine were included for evaluation. This work represents a summary of all of these studies with particular reference to peptide transporter mediated assimilation of nutrients and pharmacologically active medications.RESULTS: Assimilation of dietary protein in humans involves gastric and pancreatic enzyme hydrolysis to luminal oligopeptides and free amino acids. During the ensuing intestinal phase, these hydrolytic products are transported into the epithelial cell and, eventually, the portal vein. A critical component of this process is the uptake of intact di-peptides and tri-peptides by an independent Pep T1. A number of "peptide-mimetic" pharmaceutical agents may also be transported through this carrier, important for uptake of different antibiotics, antiviral agents and angiotensin-converting enzyme inhibitors. In addition, specific peptide products of intestinal bacteria may also be transported by Pep T1, with initiation and persistence of an immune response including increased cytokine production and associated intestinal inflammatory changes. Interestingly, these inflammatory changes may also be attenuated with orallyadministered anti-inflammatory tripeptides administered as site-specific nanoparticles and taken up by this Pep T1 transport protein. CONCLUSION: Further evaluation of the role of this transporter in treatment of

    Full Text Available In clinical holistic practice, it is recommended that ample time is spent with the gynecological or pelvic examination, especially in cases of women with suspected old emotional traumas following early childhood cases of incest or sexual abuse. The holistic principles of holding and processing should be followed with the purpose of healing the patient, re-establishing the natural relationship with the body, sexuality, and reproductive organs. Sexual violations are often forcibly repressed. It appears that the tissues that were touched during the violation often bear the trauma. It is characteristic of these patients that their love lives are often problematic and do not provide the necessary support to heal the old wounds in the soul and therapy is therefore indicated. When this is concerned with the reproductive organs, it poses particular difficulties, as the therapy can easily be experienced as a repetition of the original violation, not least due to the risk of projection and transference. There is, therefore, a need for a procedure that is familiar to and safe for the patient, for all work that involves therapeutic touching of sexual organs over and beyond what is standard medical practice. This paper presents one case story of earlier child sexual abuse and one case of temporary infertility. We have established a procedure of slow or extended pelvic examination, where time is spent to make the patient familiar with the examination and accept the whole procedure, before the treatment is initiated. The procedure is carried out with a nurse, and 3 h are set aside. It includes conversation on the present condition and symptoms; concept of boundaries; about how earlier assaults can be projected into the present; establishment of the therapeutic room as a safe place; exercises on when to say “stop”; therapeutic touch; visualization of the pelvic examination step by step beforehand; touching on the outside of the clothes with repetition of the

  6. Clinically Relevant Imaging in Tuberous Sclerosis

    Full Text Available Tuberous sclerosis (TS, also known as Bourneville disease or Bourneville-Pringle disease, is an autosomal dominant genetic disorder classically characterized by the presence of hamartomatous growths in multiple organs. TS and tuberous sclerosis complex (TSC are different terms for the same genetic condition. Both terms describe clinical changes due to mutations involving either of the two genes named TSC1 and TSC2, which regulate cell growth. The diagnosis of TSC is established using diagnostic criteria based on clinical and imaging findings. Routine screening and surveillance of patients with TSC is needed to determine the presence and extent of organ involvement, especially the brain, kidneys, and lungs, and identify the development of associated complications. As the treatment is organ specific, imaging plays a crucial role in the management of patients with TSC.

    One of the goals of translational cancer research is to understand basic 'phenomena' so that tumour response to therapy can be improved. One such phenomenon is intermittent tumour blood flow. The impact of the transient hypoxia that results from decreased tumour blood flow is now beginning to be appreciated in preclinical systems, and also receiving some attention in clinical practise. Thus in this article we review the nature and frequency of microregional blood flow changes in preclinical and clinical tumours and examine the impact of those changes on response to both radiotherapy and chemotherapy. Additionally, the implications of non-constant blood flow for both the growth of the unperturbed tumour and the regrowth of surviving tumour clonogens during and after therapy are examined.

    Early applications of diffusion weighted magnetic resonance imaging (DWI) were limited to neuroimaging, concentrating either on stroke or brain tumours. With recent advances in MRI hardware and software DWI is now increasingly being investigated for cancer assessment throughout the body. Clinical applications of DWI relating to female pelvic cancers have largely concentrated on detection, localisation and staging of disease. More recently investigators have started to evaluate the ability of DWI for determining tumour histology and even predicting the outcome of chemoradiation treatment. This article reviews the physical concepts of MR diffusion weighting, illustrates the biophysical basis of diffusion contrast and reports the clinical applications of DWI for cervical, endometrial, ovarian, rectal and bladder tumours.

    The QRS complex represents the electrical depolarization of ventricular myocardium. In the case of an undisturbed depolarization, the QRS complex has a normal configuration and duration, but abnormal electrical conduction leads to widening of the QRS complex. The block of one of the Tawara branches results in a typical bundle branch block pattern. A QRS complex that cannot be classified as bundle branch block due to an atypical configuration and contains notched R or S waves is called a fragmented QRS. The underlying pathophysiologies are manifold and include myocardial scars induced by ischemic heart disease, myocardial fibrosis due to other diseases, primary cardiac pathologies as well as systemic diseases with cardiac involvement. Pathologies on the cellular level, such as ion channel dysfunctions, also correlate with fragmented QRS. Besides the diagnostic relevance, fragmented QRS is known to have prognostic properties, for example in identifying high risk patients with coronary artery disease, cardiomyopathy, Brugada syndrome and acquired long QT syndrome; however, fragmented QRS may also be detected in ECGs of healthy individuals.

    Fascia is composed of collagenous connective tissue surrounding and interpenetrating skeletal muscle, joints, organs, nerves, and vascular beds. Fascial tissue forms a whole-body, continuous three-dimensional viscoelastic matrix of structural support. The classical concept of its mere passive role in force transmission has recently been disproven. Fascial tissue contains contractile elements enabling a modulating role in force generation and also mechanosensory fine-tuning. This hypothesis is supported by in vitro studies demonstrating an autonomous contraction of human lumbar fascia and a pharmacological induction of temporary contraction in rat fascial tissue. The ability of spontaneous regulation of fascial stiffness over a time period ranging from minutes to hours contributes more actively to musculoskeletal dynamics. Imbalance of this regulatory mechanism results in increased or decreased myofascial tonus, or diminished neuromuscular coordination, which are key contributors to the pathomechanisms of several musculoskeletal pathologies and pain syndromes. Here, we summarize anatomical and biomechanical properties of fascial tissue with a special focus on fascial dysfunctions and resulting clinical manifestations. Finally, we discuss current and future potential treatment options that can influence clinical manifestations of pain syndromes associated with fascial tissues.

  11. Clinically relevant subgroups in COPD and asthma

    Full Text Available As knowledge of airways disease has grown, it has become apparent that neither chronic obstructive pulmonary disease (COPD nor asthma is a simple, easily defined disease. In the past, treatment options for both diseases were limited; thus, there was less need to define subgroups. As treatment options have grown, so has our need to predict who will respond to new drugs. To date, identifying subgroups has been largely reported by detailed clinical characterisation or differences in pathobiology. These subgroups are commonly called “phenotypes”; however, the problem of defining what constitutes a phenotype, whether this should include comorbid diseases and how to handle changes over time has led to the term being used loosely. In this review, we describe subgroups of COPD and asthma patients whose clinical characteristics we believe have therapeutic or major prognostic implications specific to the lung, and whether these subgroups are constant over time. Finally, we will discuss whether the subgroups we describe are common to both asthma and COPD, and give some examples of how treatment might be tailored in patients where the subgroup is clear, but the label of asthma or COPD is not.

    While several lines of evidence prove that elevated concentrations of low-density lipoproteins (LDL) causally contribute to the development of atherosclerosis and its clinical consequences, high-density lipoproteins are still widely believed to exert atheroprotective effects. Hence, HDL cholesterol (HDL-C) is in general still considered as "good cholesterol". Recent research, however, suggests that this might not always be the case and that a fundamental reassessment of the clinical significance of HDL-C is warranted. This review article is based on a selective literature review. In individuals without a history of cardiovascular events, low concentrations of HDL-C are inversely associated with the risk of future cardiovascular events. This relationship may, however, not apply to patients with metabolic disorders or manifest cardiovascular disease. The classical function of HDL is to mobilise cholesterol from extrahepatic tissues for delivery to the liver for excretion. These roles in cholesterol metabolism as well as many other biological functions of HDL particles are dependent on the number as well as protein and lipid composition of HDL particles. They are poorly reflected by the HDL-C concentration. HDL can even exert negative vascular effects, if its composition is pathologically altered. High serum HDL-C is therefore no longer regarded protective. In line with this, recent pharmacological approaches to raise HDL-C concentration have not been able to show reductions of cardiovascular outcomes. In contrast to LDL cholesterol (LDL-C), HDL-C correlates with cardiovascular risk only in healthy individuals. The calculation of the ratio of LDL-C to HDL-C is not useful for all patients. Low HDL-C should prompt examination of additional metabolic and inflammatory pathologies. An increase in HDL-C through lifestyle change (smoking cessation, physical exercise) has positive effects and is recommended. However, HDL-C is currently not a valid target for drug therapy.

    Question answering systems try to give precise answers to a user's question posed in natural language. It is of utmost importance that the answers returned are relevant to the user's question. For clinical QA, the trustworthiness of answers is another important issue. Limiting the document collection to certified websites helps to improve the trustworthiness of answers. On the other hand, limited document collections are known to harm the relevancy of answers. We show, however, in a comparative evaluation, that promoting trustworthiness has no negative effect on the relevance of the retrieved answers in our clinical QA system. On the contrary, the answers found are in general more relevant.

  14. Clinical relevance of hepatitis B virus variants

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    The hepatitis B virus (HBV) is a global public health problem with more than 240 million people chronicallyinfected worldwide, who are at risk for end-stage liverdisease and hepatocellular carcinoma. There are anestimated 600000 deaths annually from complications ofHBV-related liver disease. Antiviral therapy with nucleos/tide analogs (NA) targeting the HBV polymerase (P) caninhibit disease progression by long-term suppression ofHBV replication. However, treatment may fail with firstgeneration NA therapy due to the emergence of drugresistantmutants, as well as incomplete medicationadherence. The HBV replicates via an error-prone reversetranscriptase leading to quasispecies. Due to overlappingopen reading frames mutations within the HBV P cancause concomitant changes in the HBV surface gene (S )and vice versa. HBV quasispecies diversity is associatedwith response to antiviral therapy, disease severity andlong-term clinical outcomes. Specific mutants havebeen associated with antiviral drug resistance, immuneescape, liver fibrosis development and tumorgenesis.An understanding of HBV variants and their clinicalrelevance may be important for monitoring chronichepatitis B disease progression and treatment response.In this review, we will discuss HBV molecular virology,mechanism of variant development, and their potentialclinical impact.

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

    2007-01-01

    Irritable bowel syndrome (IBS) and chronic pelvic pain (CPP) are both somatoform disorders with a high prevalence within the population in general. The objective was to compare both entities, to find the differences and the similarities related to epidemiology and psychosocial aspects like stressful life events, physical and sexual abuse, illness behaviour and comorbidity. The technical literature was reviewed systematically from 1971 to 2006 and compared. According to literature, IBS and CPP seem to be one rather than two different entities with the same localisation of pain. Both syndromes also are similar concerning prevalence, the coexistence of mental and somatoform disorders, the common history of sexual and physical abuse in the past and their health care utilization. It could be shown that there were many similarities between IBS and CPR Nevertheless both are traded as different clinical pictures as far. Therefore it seems to be reasonable and necessary to generate a common diagnosis algorithm and to bring gynaecologists and gastroenterologists into dialogue.

    @@ Pelvic pain is one of the most common symptoms in gynecologic outpatients. Primary dysmenorrhea, acute or chronic pelvic inflammatory disease, endometriosis, post-operational pelvic adhesion, blood stagnation of pelvic vein, etc., are mentioned as the often encountered causes of pelvic pain. It has been reported in the recent ten or more years that intramuscular injection of vitamin K3 (Vit K3) could relieve pain induced by smooth muscle spasm(1,2). In order to evaluate the effect of Vit K3 administered by acupoint injection in relieving pelvic pain, 180 patients were treated and observed from April 1997 to April 1999 in our hospital, and good therapeutic effect was obtained. It was reported as follows.

  18. A simple method to obtain consistent and clinically meaningful pelvic angles from euler angles during gait analysis.

    Wren, Tishya A L; Mitiguy, Paul C

    2007-08-01

    Clinical gait analysis usually describes joint kinematics using Euler angles, which depend on the sequence of rotation. Studies have shown that pelvic obliquity angles from the traditional tilt-obliquity-rotation (TOR) Euler angle sequence can deviate considerably from clinical expectations and have suggested that a rotation-obliquity-tilt (ROT) Euler angle sequence be used instead. We propose a simple alternate approach in which clinical joint angles are defined and exactly calculated in terms of Euler angles from any rotation sequence. Equations were derived to calculate clinical pelvic elevation, progression, and lean angles from TOR and ROT Euler angles. For the ROT Euler angles, obliquity was exactly the same as the clinical elevation angle, rotation was similar to the clinical progression angle, and tilt was similar to the clinical lean angle. Greater differences were observed for TOR. These results support previous findings that ROT is preferable to TOR for calculating pelvic Euler angles for clinical interpretation. However, we suggest that exact clinical angles can and should be obtained through a few extra calculations as demonstrated in this technical note.

    Laboratory observer performance measurements, receiver operating characteristic (ROC) and free-response ROC (FROC) differ from actual clinical interpretations in several respects, which could compromise their clinical relevance. The objective of this study was to develop a method for quantifying the clinical relevance of a laboratory paradigm and apply it to compare the ROC and FROC paradigms in a nodule detection task. The original prospective interpretations of 80 digital chest radiographs were classified by the truth panel as correct (C=1) or incorrect (C=0), depending on correlation with additional imaging, and the average of C was interpreted as the clinical figure of merit. FROC data were acquired for 21 radiologists and ROC data were inferred using the highest ratings. The areas under the ROC and alternative FROC curves were used as laboratory figures of merit. Bootstrap analysis was conducted to estimate conventional agreement measures between laboratory and clinical figures of merit. Also computed was a pseudovalue-based image-level correctness measure of the laboratory interpretations, whose association with C as measured by the area (rAUC) under an appropriately defined relevance ROC curve, is as a measure of the clinical relevance of a laboratory paradigm. Low correlations (e.g. κ=0.244) and near chance level rAUC values (e.g. 0.598), attributable to differences between the clinical and laboratory paradigms, were observed. The absolute width of the confidence interval was 0.38 for the interparadigm differences of the conventional measures and 0.14 for the difference of the rAUCs. The rAUC measure was consistent with the traditional measures but was more sensitive to the differences in clinical relevance. A new relevance ROC method for quantifying the clinical relevance of a laboratory paradigm is proposed.

    Full Text Available Background: To examine the association among pelvic girdle pain (PGP, urinary incontinence (UI and pelvic floor muscle (PFM function in pregnant women in second and third trimester. Methods: 300 pregnant women who admitted for standard pregnancy care were enrolled in the study. Urinary incontinency was measured via the international consultation on incontinence questionnaire short form. Pelvic girdle pain was diagnosed according to existing guidelines. Vaginal examination assessed pelvic muscles contract- relax patterns and muscle strength. The software stata version 13 (Stata Corp., TX, USA was used for data analysis. Results: Overall 300 women (150 with PGP and 150 without PGP were included in final analyses. There was not significant differences between the demographic data including, body mass index before pregnancy, maternal age, mode of delivery. Prevalence of urinary incontinence in women with pelvic girdle pain was 41.5 percent (CI 95%: 32.01- 51.48 while the prevalence of urinary incontinence in women without pain was 21.9 percent (CI 95%: 14.99-30.03. Using logistic regression, the relationship between urinary incontinence and pelvic girdle pain was significant. (CI 95%: 1.07-3.31, P=0.02. Multivariate logistic regression analysis was used to evaluate the relationship between PGP and pelvic floor muscle function and results showed that pelvic floor muscle strength in women with PGP was significantly lower than women without PGP. (CI 95%: 0.24-0.68, OR= 0.4, P<0.001. The duration of the contraction of the pelvic floor muscles in patients with PGP was significantly shorter than women without PGP. (CI 95%: 0.21-0.60, OR =0.35, P<0.001. Conclusion: There was a significant association between pelvic girdle pain and urinary incontinence during the second and third trimesters of pregnancy and also the pelvic floor muscle strength and duration of the contraction of the pelvic floor muscles in women with pelvic girdle pain was significantly

    The aim of this study was to identify factors that can predict clinical course among patients hospitalized with pelvic inflammatory disease (PID). Ninety-three patients who needed hospitalization with a diagnosis of PID were retrospectively studied. Patients who were discharged within 7 days by conservative treatment were defined as favorable course cases (n = 44). Patients who needed more than 7 days of hospitalization and/or surgery were defined as poor course cases (n = 49). Twenty variables were evaluated by univariate and logistic regression analysis: age, history of pregnancy/delivery, gynecological open/laparoscopic surgery, PID, oral contraceptives/intrauterine device use and intrauterine operation before onset, body temperature, signs of peritoneal irritation, vomiting/diarrhea, abnormal vaginal discharge, endometriosis/fibroid/adenomyosis/any cystic lesion detected by ultrasonography, white blood cell counts/C-reactive protein (CRP) levels . The cut-off value was calculated by receiver-operator curve (ROC) analysis. Factors associated with poor clinical course were advanced age (P < 0.01), history of gynecological open surgery (P < 0.05), any cystic lesion detected by ultrasonography (P < 0.05) and high CRP levels (P < 0.05). High CRP levels and intrauterine operation before onset were independently associated with poor clinical course. The cut-off value for CRP was 4.4 mg/dL. This study identified variables that can predict poor clinical course of PID. These results can assist gynecologists with identifying patients at risk and optimizing the choice of management. © 2013 The Authors.

    To prospectively evaluate feasibility, image quality and diagnostic accuracy of dynamic MR imaging the pelvic floor at 3.0 T in patients with urinary incontinence and to compare these results with those of MRI performed at 1.5 T. Ten patients with the diagnosis of urinary incontinence (clinical symptoms, clinical examination, pelvic ultrasound) were examined with a dynamic balanced FFE (B-FFE) sequence at 1.5 T and 3.0 T on the same day in a randomized order. Spatial (1.5 x 1.5 x 8 mm) and temporal (0.44 s) resolution at 3.0 T were comparable to the 1.5-T B-FFE sequence. Two radiologists assessed visual signal to noise (three-point scale), artefact level (five-point scale) and final MR diagnoses with regard to pelvic floor weakness (independent analysis). The diagnoses obtained at 1.5-T field strength and the results of the clinical tests served as standard of reference. In addition, ROI-based quantitative measurements were performed to assess different tissue contrasts at both field strengths. Data were analyzed for statistical differences by using the Wilcoxon's matched pairs test and the marginal homogeneity test. Visual signal to noise was rated higher at 3.0 T for all ten studies by both radiologists. With regard to artefact level, there was no statistically significant difference between the studies obtained at 3.0 T as compared to the corresponding 1.5-T studies (marginal homogeneity test: p = 0.18 for reviewer 1 and 0.41 for reviewer 2). Mean artefact level was rated minor to moderate by both reviewers for both field strengths (excellent interobserver agreement with Kendall-W value of 0.973). Except for a higher tissue contrast between fat and urethra at 1.5 T, there were no statistically significant differences between tissue contrast at 1.5 T as compared to 3.0 T (Wilcoxon's test). Final MR diagnoses regarding pelvic floor weakness did not differ between 3.0-T and 1.5-T field strength and correlated well with the results of the clinical tests

    Objective To evaluate factors predisposing women to chronic and recurrent pelvic pain. Design, data sources, and methods Systematic review of relevant studies without language restrictions identified through Medline, Embase, PsycINFO, Cochrane Library. SCISEARCH, conference papers, and bibliographies of retrieved primary and review articles. Two reviewers independently extracted data on study characteristics, quality, and results. Exposure to risk factors was compared between women with and without pelvic pain. Results were pooled within subgroups defined by type of pain and risk factors. Results There were 122 studies (in 111 articles) of which 63 (in 64 286 women) evaluated 54 risk factors for dysmenorrhoea, 19 (in 18 601 women) evaluated 14 risk factors for dyspareunia, and 40 (in 12 040 women) evaluated 48 factors for non-cyclical pelvic pain. Age < 30 years, low body mass index, smoking, earlier menarche (< 12 years), longer cycles, heavy menstrual flow, nulliparity, premenstrual syndrome, sterilisation, clinically suspected pelvic inflammatory disease, sexual abuse, and psychological symptoms were associated with dysmenorrhoea. Younger age at first childbirth, exercise, and oral contraceptives were negatively associated with dysmenorrhoea. Menopause, pelvic inflammatory disease, sexual abuse, anxiety, and depression were associated with dyspareunia. Drug or alcohol abuse, miscarriage, heavy menstrual flow, pelvic inflammatory disease, previous caesarean section, pelvic pathology, abuse, and psychological comorbidity were associated with an increased risk of non-cyclical pelvic pain. Conclusion Several gynaecological and psychosocial factors are strongly associated with chronic pelvic pain. Randomised controlled trials of interventions targeting these potentially modifiable factors are needed to assess their clinical relevance in chronic pelvic pain. PMID:16484239

    To evaluate the clinical relevance of pharmacist intervention on patient care in emergencies, to determine the severity of detected errors. Second, to analyse the most frequent types of interventions and type of drugs involved and to evaluate the clinical pharmacist's activity. A 6-month observational prospective study of pharmacist intervention in the Emergency Department (ED) at a 400-bed hospital in Spain was performed to record interventions carried out by the clinical pharmacists. We determined whether the intervention occurred in the process of medication reconciliation or another activity, and whether the drug involved belonged to the High-Alert Medications Institute for Safe Medication Practices (ISMP) list. To evaluate the severity of the errors detected and clinical relevance of the pharmacist intervention, a modified assessment scale of Overhage and Lukes was used. Relationship between clinical relevance of pharmacist intervention and the severity of medication errors was assessed using ORs and Spearman's correlation coefficient. During the observation period, pharmacists reviewed the pharmacotherapy history and medication orders of 2984 patients. A total of 991 interventions were recorded in 557 patients; 67.2% of the errors were detected during medication reconciliation. Medication errors were considered severe in 57.2% of cases and 64.9% of pharmacist intervention were considered relevant. About 10.9% of the drugs involved are in the High-Alert Medications ISMP list. The severity of the medication error and the clinical significance of the pharmacist intervention were correlated (Spearman's ρ=0.728/pclinical pharmacists identified and intervened on a high number of severe medication errors. This suggests that emergency services will benefit from pharmacist-provided drug therapy services. Published by the BMJ Publishing Group Limited.

    To prospectively investigate the survival benefit of para-aortic lymphadenectomy, we launched a new study, the JCOG1412. This is a randomized Phase III trial to confirm the superiority of pelvic and para-aortic lymphadenectomy to pelvic lymphadenectomy alone. Patients corresponding to possible FIGO Stage IB, II, IIIA, IIIB, and a part of IIIC1 are eligible for the first registration before surgery. Next, those patients without evidence of para-aortic lymph node metastasis and multiple pelvic lymph node metastasis during surgery will be included in the second registration and randomized to either the pelvic lymphadenectomy alone arm or the pelvic and para-aortic lymphadenectomy arm. After the initial surgery, patients with post-operative recurrence risks receive adjuvant chemotherapy. The primary endpoint is overall survival. Secondary endpoints include relapse-free survival, short-term surgical outcomes, adverse events related to adjuvant chemotherapy and recurrence patterns.

    Objective: To observe the therapeutic effects of Qi Jie Granule (芪竭颗粒) on chronic pelvic inflammation. Method: The therapeutic effect, T-lymphocytic subgroups and indexes of blood rheology were observed when 102 cases of chronic pelvic inflammation in the treatment group were treated with Qi Jie Granule, and another 70 cases were treated with Qian Jin Pian as the controls. Results: The total effective rate was 96.08% in the treatment group, but 84.29% in the control group with a significant difference between the two groups (P<0.01). Qi Jie Granule was also found effective in improving blood viscosity and regulating T-lymphocytic subgroups, and the difference before and after the treatment was also very significant (P<0.05 or P<0.01). Conclusion: The nature of chronic pelvic inflammation is qi deficiency and blood stasis in accordance with the theory of traditional Chinese medicine (TCM). As a drug that is indicated for chronic pelvic inflammation, its mechanism may be related to the improved blood circulation, accelerated inflammatory absorption and regulated immune function.

    2016-07-01

    Introduction The aim of this study was to establish the prevalence of pelvic floor symptoms in women referred to a colorectal two-week wait (2WW) clinic with suspected colorectal cancer. Methods A questionnaire assessing faecal incontinence (FI) (Wexner score) and obstructed defecation syndrome (ODS) (Renzi score) was offered to 98 consecutive female patients attending a colorectal 2WW clinic at a single trust. Results Overall, 56 (57%) of the 98 patients had significant ODS and/or FI (scores >9/20), 33 (34%) had ODS and 40 (41%) had FI. Seventeen patients (17%) had both ODS and FI. Analysis of the 63 patients referred with a change in bowel habit (CIBH) showed 40 (63%) to be Renzi and/or Wexner positive compared with 16 (46%) of the 35 patients who presented without CIBH (p=0.095, Fisher's exact test). Further analysis showed that 31 (78%) of the 40 patients with FI presented with CIBH compared with 32 (55%) of the 58 without FI (p=0.032). In terms of ODS, 23 (70%) of the 33 patients with ODS presented with CIBH compared with 40 (62%) of the 65 without ODS (p=0.506). Conclusions Over half of the female patients attending our colorectal 2WW clinic had significant pelvic floor dysfunction (FI/ODS), which may account for their symptoms (especially in the CIBH referral category). While it is important for malignancy to be excluded, many patients may benefit from investigation and management of their pelvic floor dysfunction as the cause for their presenting symptoms.

    Introduction: The purpose of the study was to assess the usefulness of dynamic MRI in patients with pelvic organ prolapse after pelvic floor repair with polypropylene mesh. Materials and methods: Fifteen consecutive patients (mean age 66.5 years) who were scheduled for either anterior (n = 9) or posterior (n = 6) pelvic floor repair were prospectively evaluated by clinical assessment and dynamic MRI 1 day before and 3 months after surgery. MRI diagnoses and MRI measurements of relevant anatomical points at rest and on straining were analysed before and after surgery. Results: At follow-up assessment 93.3% of all patients were clinically cured. Dynamic MRI showed newly developed (n = 6) or increased (n = 6) pelvic organ prolapse in 80% (n = 12) of all patients 3 months after pelvic floor repair. Most of them (n = 11; 91.7%) affected the untreated pelvic floor compartment. On straining anatomical points of reference in the anterior pelvic floor compartment were significantly (p < 0.05) elevated after anterior repair and rectal bulging was significantly (p = 0.036) reduced after posterior pelvic floor repair. Conclusions: In this study dynamic MRI could verify the effective support of anterior and posterior pelvic floor structures by anterior and posterior polypropylene implant respectively. But dynamic MRI demonstrates if one compartment of the pelvic floor is repaired another compartment frequently (73.3%) develops dysfunction. These results did not correspond to clinical symptoms on short-term follow-up (3 months). Studies with long-term follow-up are necessary to prove if dynamic MRI can reliably identify clinically significant pelvic organ prolapse after pelvic floor repair before the onset of symptoms.

    To investigatethe clinical significance of hip rotation center location after reconstruction with modular hemipelvic prostheses for periacetabula tumors. Forty-two patients who received periacetabular tumor resection and reconstruction with modular hemipelvic prosthesis between January 2004 and January 2014 in our institute were included. Postoperative complications, function (measured by MSTS score), survival rate and recurrence rate were analyzed. The position of prosthetic hip rotation center was measured. By its deviation angle from the ideal rotation center, the patients were divided into inward group, normal group and outward group in the horizontal level, and upward group, normal group and downward group in the vertical direction. And the relationship between positional difference of prosthetic hip rotation center and function at 1 month, 3 months, 6 months and 12 months after surgery was analyzed. Of forty-two cases in total, 25 patients were male and 17 patients were female. The age of the patients ranged from 12 and 69 years (median, 38 years). The minimal followup period was 12 months (mean,36 months; range,12-86 months). The complication rate was 31.0% and hip dislocation rate was 7.1%. The overall survival rate was 69.4% at 3 years and 43.7% at 5 years. After 1 month, 3 months, 6 months, the function of the reconstructed hip gradually improved, with MSTS score showing an increasing trend. The MSTS scores at these three time points were compared, the difference was statistically significant (P 0.05). The deviation of hip rotation center in the longitudinal direction and the horizontal direction did not affect the function of the hip (P > 0.05). It is safe and effective for patients with pelvic tumor to receive modular hemipelvic prosthesis reconstruction once the prosthesis is fixed in the most firmly position, where soft tissue fully covered, the muscles could be rebuilt more easily and where the eccentricity of the femoral got a certain degree of

    In last few years, special attention has been given to food-induced allergies, in which hazelnut allergy is highlighted. Hazelnut is one of the most commonly consumed tree nuts, being largely used by the food industry in a variety of processed foods. It has been regarded as a food with potential health benefits, but also as a source of allergens capable of inducing mild to severe allergic reactions in sensitized individuals. Considering the great number of reports addressing hazelnut allergens, with an estimated increasing trend, this review intends to assemble all the relevant information available so far on the following main issues: prevalence of tree nut allergy, clinical threshold levels, molecular characterization of hazelnut allergens (Cor a 1, Cor a 2, Cor a 8, Cor a 9, Cor a 10, Cor a 11, Cor a 12, Cor a 14, and Cor a TLP) and their clinical relevance, and methodologies for detection of hazelnut allergens in foods. A comprehensive overview of the current data about the molecular characterization of hazelnut allergens is presented, relating to biochemical classification and biological function with clinical importance. Recent advances in hazelnut allergen detection methodologies are summarized and compared, including all the novel protein-based and DNA-based approaches.

    Evisceration of the pelvic organs (EPO) is a fairly uncommon surgical treatment that removes all organs from a patient's pelvic cavity. We use gracilis musculocutaneous flap to repair pelvic floor after EPO. Over the period from November 2013 to December 2014 we carried out EPO with reconstructive repair of the pelvic floor with gracilis musculocutaneous flap in 10 patients with locally advanced pelvic tumors. We describe the surgical procedure and surgical outcomes in these patients. Mean age of the patients was 55 years. Mean duration of EPO with the pelvic floor repair was 285 min., mean blood loss--595 mL and the average length of hospital stay--19 days. Gracilis musculocutaneous flap has a sufficient arterial supply and mobility for pelvic floor reconstruction. Necrosis of flap's distal edge occurred in one of the 10 clinical cases, while the remaining flaps were fully preserved. Complete healing of wounds with no signs of weakening of the pelvic floor muscles was observed in all cases. Pelvic floor reconstruction is an essential procedure in order to reduce complications associated with the evisceration of the pelvic organs. The Gracilis musculocutaneous flap is the logical alternative to repair pelvic floor defect. It does not contribute to complications like functional deficiency of the lower limbs, complications of stoma formation or weakening of the muscles of the anterior abdominal wall.

    Social and psychological factors have long been proposed as being of importance in a sizeable subgroup of women complaining of unexplained chronic pelvic pain (CPP). The aim of this study was to examine this in two subgroups of CPP patients, thereby eliminating pain alone as the determining variable. Consecutive attenders at a clinic for CPP were assessed on a range of somatic, historical, social, and psychological variables using detailed interviews and questionnaires. They were subsequently allocated to one of two groups, based on the presence or absence of pelvic venous congestion (PVC). Significant associations emerged between some social arrangements, paternal parenting, and patterns of hostility in the group with pelvic venous congestion. The groups also differed in patterns of family illness, and the congested group tended to report more childhood sexual abuse (CSA). Clear case definition in CPP is important. In the subgroup with pelvic venous congestion early social experience may play an important role. Father-daughter relationships may be particularly relevant. Hostility patterns may influence the development of the condition. CSA does not appear to play a specific role in all unexplained CPP cases, but may have relevance for the subgroup with pelvic venous congestion.

  2. Sensitization to lupine flour: is it clinically relevant?

    Lupinus angustifolius (blue lupine) is used for human and animal consumption. Currently, the lupine content in bread varies from 0% to 10% and from 0.5% to 3% in pastry. Although lupine flour is present in many products, anaphylaxis on lupine flour is rarely seen. The aim of our study was to determine the clinical relevance of sensitization to lupine flour. From October 2004 until October 2005, we performed skin prick tests (SPT) with lupine flour, peanut and soy extracts in consecutive patients attending our allergy clinic with a suspected food allergy. In patients sensitized to lupine flour, double-blind placebo-controlled food challenges (DBPCFC) were performed and specific IgE was measured. We tested 372 patients. SPTs with peanut, soy and lupine flour were positive in 135, 58 and 22 patients, respectively. Nine patients with sensitization to lupine flour underwent DBPCFC, which was negative in eight cases. In contrast, one patient experienced significant symptoms. Four of these nine patients suspected lupine by history. Two other patients with a positive history to lupine declined from challenges. In these patients, a 3-day dietary record showed that they could consume lupine without symptoms. Specific IgE in the serum was positive for L. angustifolius, peanut and soy in all nine patients. These results demonstrate that clinical lupine allergy is very uncommon, even in the presence of sensitization to lupine flour. The estimated prevalence of lupine allergy, among patients with a suspected food allergy, referred to a tertiary allergy centre in the Netherlands is 0.27-0.81%. In most, although not all cases, sensitization is not clinically relevant and is most likely caused by cross-sensitization to peanut. In selected cases, eliciting doses are low, making significant reactions possible. © 2010 Blackwell Publishing Ltd.

    The aging world population had led to an increase in the prevalence of Alzheimer's disease (AD). The drugs used to slow down the onset of AD, galantamine, donepezil, rivastigmine and memantine, are generally well-tolerated. However, drug interactions between these drugs and other drugs are an important aspect of patient safety that should be borne in mind, particularly given the high burden of polypharmacy in the elderly. The aim of this review is to provide an updated review of clinically significant drug-drug interactions concerning drugs approved for AD. PubMed was searched for relevant keywords. No time limit was imposed but only articles in English published in peer-reviewed journals were selected. Relevant literature was also identified from the references of identified articles. Further information was obtained from drug summary of product characteristics. The major pharmacokinetic interactions identified concerned fluoxetine, paroxetine and ketoconazole when used with galantamine or donepezil. On the other hand, the major potential pharmacodynamic interactions concerned anti-dementia drugs and general anesthesia agents, anti-cholinergic drugs, conventional antipsychotics and bradycardia-inducing drugs. In clinical practice memantine shows a lower potential for pharmacodynamic drug-drug interactions (DDIs) compared to other drug classes. In conclusion, the concomitant use of anti-dementia drugs with other drugs can have variable clinical effects, making appropriate prescribing of these drugs very challenging. A simple and coherent way of presenting evidence on complex drug interaction information from heterogenous sources to clinicians is needed in order for the voluminous data available to have an impact on clinical practice.

    In 2001, the US Food and Drug Administration (FDA) approved the first transvaginal mesh kit to treat pelvic organ prolapse (POP). Since the introduction of vaginal mesh kits, some vaginal meshes have been associated with chronic pelvic pain after reconstructive pelvic floor surgery. Pelvic pain results in between 0 % and 30 % of patients following transvaginal mesh placement. Common causes of chronic pelvic pain include pelvic floor muscle spasm, pudendal neuralgia, and infection. Paucity of data exists on the effective management of chronic pelvic pain after pelvic reconstructive surgery with mesh. We outline the management of chronic pelvic pain after transvaginal mesh placement for reconstructive pelvic floor repair based on our clinical experience and adaptation of data used in other aspects of managing chronic pelvic pain conditions.

    Objectives: We sought to define the role of laparoscopy in identifying the clinical significance, cause, and association between adhesions and chronic pelvic pain. Methods: A retrospective chart review was conducted from October 2004 to July 2005, at the Kiel School of Gynecological Endoscopy, University Hospitals Schleswig-Holstein, Campus Kiel, Germany. Included in the study was the analysis of 462 laparoscopic procedures; 275 (59.5%) of the patients undergoing these procedures had pelvic or abdominal adhesions. Of these, 84 (30.5%) patients were admitted with the main complaint of chronic pelvic pain. Further evaluation and assessment of this group was carried out. Results: Among those patients with adhesions, the second most frequent reason for admission was chronic pelvic pain (30.5%) (P<0.0005). In our study, adhesions were found in 79.2% (n=84) of patients (n=106) with chronic pelvic pain. These adhesions were thin- filmy (19.0%) or thick-fibrous (81.0%) adhesions containing blood vessels. Thick-fibrous adhesions were present in 50.0% of patients at multiple abdominopelvic sites (P<0.005). Conclusions: Thick-fibrous adhesions that extend beyond the pelvic sidewall can cause significant chronic abdominopelvic pain. PMID:17931511

    Cerebrovascular malformations affect more than 3% of the population, exposing them to a lifetime risk of hemorrhagic stroke, seizures, and focal neurological deficits. Cerebral cavernous malformations (CCMs) exhibit an immature vessel wall, a brittle hemorrhagic tendency, and epileptogenesis, whereas arteriovenous malformations (AVMs) lack capillary beds and manifest apoplectic bleeding under high-flow conditions. There are also more benign venous anomalies, capillary malformations, and lesions with mixed and transitional features. Advances have been made toward understanding the natural history, radiological and pathological correlates, and clinical management. Yet, mechanisms of lesion genesis and clinical manifestations remain largely unknown, and the clinical behavior in individual patients is highly unpredictable. Lesion pathogenesis likely involves abnormal assembly or maintenance of blood vessels, resulting in dysmorphic vessel phenotypes. Familial CCM disease is in part caused by mutations in a cytoskeletal-related protein that is likely integral to interendothelial cell connectivity and maturation of the vascular wall. Rare familial forms of AVM disease have been correlated with two different transforming growth factor-beta receptor components, possibly causing disturbance in signaling during vascular assembly. Relevance of these mechanisms to the more common and otherwise identical sporadic CCM and AVM lesions is being explored. In this report, basic mechanisms of vasculogenesis and angiogenesis and how they possibly relate to the common cerebrovascular malformation lesions are reviewed. Novel concepts are discussed related to the cellular, molecular, and genetic substrates in CCM and AVM as well as to how this knowledge can be applied to predict, explain, and possibly modify clinical disease manifestations.

    We studied selected epidemiologic, clinical, serologic, and microbiologic findings and their interrelationships among 57 women with acute pelvic inflammatory disease (PID). Cervical cultures positive for Neisseria gonorrhoeae alone and for both N. gonorrhoeae and Chlamydia trachomatis were associated with young age, nulliparity, and use of birth-control pills. Positive serologic findings for C. trachomatis were associated with the isolation of C. trachomatis and/or N. gonorrhoeae from the cervix and predicted the presence of a pelvic mass. High levels of antibody to Mycoplasma hominis were associated with increasing age and parity, and predicted a low concentration of C-reactive protein (CRP), a long hospital stay, and a high convalescent-phase erythrocyte sedimentation rate (ESR). Women with recurrent PID had higher titers of antibody to C. trachomatis than those with primary PID. The use of an intrauterine contraceptive device predicted high CRP, high acute-phase ESR, long hospital stay, and was frequently associated with positive serologic tests for M. hominis. These results demonstrate that the clinical picture of PID depends not only on the microorganisms involved but also on many epidemiologic factors such as age, contraceptive method, and parity.

    Uterine leiomyomas (fibroids), the most common benign tumor in women of childbearing age, can cause symptoms including dysmenorrhea, menorrhagia, urinary symptoms, pain and infertility. Hysterectomy is a common approach to treating uterine fibroids, and less invasive surgical approaches such as myomectomy and uterine artery embolization also have been shown to alleviate symptoms. Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is the only totally non-invasive surgical approved method for treating uterine fibroids. In clinical trials, MRgFUS resulted in significant relief of uterine fibroid symptoms. The safe and effective use of MRgFUS is affected by fibroid type and location, position relative to adjacent anatomical structures and the presence of co-existent pelvic disease. Additionally, successful outcomes with MRgFUS have been correlated with the volume of fibroids ablated during the procedure. Thus, selection of patients in whom sufficient fibroid volumes can be treated safely using the MRgFUS system is critical for successful outcomes. The MR images in this pictorial essay provide examples of uterine fibroids for which MRgFUS should be considered and is designed to facilitate the selection of patients for whom MRgFUS is most likely to provide sustained symptom relief.

  11. Functional imaging of the pelvic floor

    Energy Technology Data Exchange (ETDEWEB)

    2003-08-01

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

    2012-08-01

    Acute myelogenous leukemia (AML) is an extremely heterogeneous neoplasm with several clinical, pathological, genetic and molecular subtypes. Combinations of various doses and schedules of cytarabine and different anthracyclines have been the mainstay of treatment for all forms of AMLs in adult patients. Although this combination, with the addition of an occasional third agent, remains effective for treatment of some young-adult patients with de novo AML, the prognosis of AML secondary to myelodysplastic syndromes or myeloproliferative neoplasms, treatment-related AML, relapsed or refractory AML, and AML that occurs in older populations remains grim. Taken into account the heterogeneity of AML, one size does not and should not be tried to fit all. In this article, the authors review currently understood, applicable and relevant findings related to cytarabine and anthracycline drug-metabolizing enzymes and drug transporters in adult patients with AML. To provide a prime-time example of clinical applicability of pharmacogenomics in distinguishing a subset of patients with AML who might be better responders to farnesyltransferase inhibitors, the authors also reviewed findings related to a two-gene transcript signature consisting of high RASGRP1 and low APTX, the ratio of which appears to positively predict clinical response in AML patients treated with farnesyltransferase inhibitors.

    This review describes different aspects to consider when developing implantable pressure sensor systems. Measurement of pressure is in general highly important in clinical practice and medical research. Due to the small size, light weight and low energy consumption Micro Electro Mechanical Systems (MEMS) technology represents new possibilities for monitoring of physiological parameters inside the human body. Development of clinical relevant sensors requires close collaboration between technological experts and medical clinicians. Site of operation, size restrictions, patient safety, and required measurement range and resolution, are only some conditions that must be taken into account. An implantable device has to operate under very hostile conditions. Long-term in vivo pressure measurements are particularly demanding because the pressure sensitive part of the sensor must be in direct or indirect physical contact with the medium for which we want to detect the pressure. New sensor packaging concepts are demanded and must be developed through combined effort between scientists in MEMS technology, material science, and biology. Before launching a new medical device on the market, clinical studies must be performed.

    Studies evaluating the association between obesity and pelvic organ prolapse report estimates that range from negative to positive associations. Heterogeneous definitions for pelvic organ prolapse and variable choices for categorizing obesity measures have made it challenging to conduct meta-analysis. We systematically evaluated evidence to provide quantitative summaries of association between degrees of obesity and pelvic organ prolapse, and identify sources of heterogeneity. We searched for all indexed publications relevant to pelvic organ prolapse up until June 18, 2015, in PubMed/MEDLINE to identify analytical observational studies published in English that reported risk ratios (relative risk, odds ratio, or hazard ratio) for body mass index categories in relation to pelvic organ prolapse. Random effects meta-analyses were conducted to report associations with pelvic organ prolapse for overweight and obese body mass index categories compared with women in the normal-weight category (referent: body mass index obesity and pelvic organ prolapse, 22 eligible studies provided effect estimates for meta-analysis of the overweight and obese body mass index categories. Compared with the referent category, women in the overweight and obese categories had meta-analysis risk ratios of at least 1.36 (95% confidence interval, 1.20-1.53) and at least 1.47 (95% confidence interval, 1.35-1.59), respectively. Subgroup analyses showed effect estimates for objectively measured clinically significant pelvic organ prolapse were higher than for self-reported pelvic organ prolapse. Other potential sources of heterogeneity included proportion of postmenopausal women in study and reported study design. Overweight and obese women are more likely to have pelvic organ prolapse compared with women with body mass index in the normal range. The finding that the associations for obesity measures were strongest for objectively measured, clinically significant pelvic organ prolapse further

    Ureteric herniations are extremely rare. We are reporting the case of a 57-year-old female presenting with an upper urinary tract sepsis due to a pelvic ureteral herniation into the supra-piriform sciatic foramen. The diagnosis was made by the CT scan and the treatment was performed in two steps: first the upper urinary tract was drained, and then the hernia was surgically treated. Although ureteral hernias are exceptional causes for nephritic colic, urologists must be aware of the specificity of the diagnosis and of the treatment in order to avoid complications.

    Full Text Available Streptococcus pyogenes (group A streptococci, GAS is an exclusive human bacterial pathogen. The virulence potential of this species is tremendous. Interactions with humans range from asymptomatic carriage over mild and superficial infections of skin and mucosal membranes up to systemic purulent toxic-invasive disease manifestations. Particularly the latter are a severe threat for predisposed patients and lead to significant death tolls worldwide. This places GAS among the most important Gram-positive bacterial pathogens. Many recent reviews have highlighted the GAS repertoire of virulence factors, regulators and regulatory circuits/networks that enable GAS to colonize the host and to deal with all levels of the host immune defense. This covers in vitro and in vivo studies, including animal infection studies based on mice and more relevant, macaque monkeys. It is now appreciated that GAS, like many other bacterial species, do not necessarily exclusively live in a planktonic lifestyle. GAS is capable of microcolony and biofilm formation on host cells and tissues. We are now beginning to understand that this feature significantly contributes to GAS pathogenesis. In this review we will discuss the current knowledge on GAS biofilm formation, the biofilm-phenotype associated virulence factors, regulatory aspects of biofilm formation, the clinical relevance, and finally contemporary treatment regimens and future treatment options.

    Atherosclerosis is the main contributor to cardiovascular disease and leads to intimal plaque formation, which may progress to plaque rupture with subsequent thromboembolic events and/or occlusion of the arterial lumen. There is increasing evidence that the development or progression of atherosclerosis is associated with advanced glycation endproducts (AGEs). AGEs are a heterogeneous group of compounds formed by the non-enzymatic reaction of reducing sugars with proteins, lipids, and nucleic acids. An increased understanding of the mechanisms of formation and interaction of AGEs has allowed the development of several potential anti-AGE strategies. This review summarizes AGE formation and biochemistry, the pathogeneic role of AGEs in cardiovascular disease, anti-AGE therapies and clinical relevance to vascular surgery.

    The author discusses ways to make the history of psychology course relevant for a clinical psychology doctoral program within a multidenominational Protestant theological seminary. She uses a personalist orientation to emphasize the need to integrate psychology, philosophy, and theology. She differentiates among the intrapersonal, interpersonal, impersonal, and transpersonal dimensions of experience. She illustrates the rich multidisciplinary historical roots of contemporary psychology by tracing the the history of the term psychology and examining its meanings in the existential psychology of Søren Kierkegaard and in the 19th-century novel. She includes brief histories of the "new psychology" and of the unconscious. She describes how she uses the field of psychotheological integration to illustrate principles of historiography and summarizes resources used to supplement traditional textbooks.

    Although previous studies show that physicians generally agree that nutrition knowledge is important for their daily clinical practice, several other studies report their poor knowledge of the subject. One of the strongest reasons given for this is the non-incorporation of Nutrition as a compulsory subject for the medical sciences degree. Dietary counselling and assessment of the patients' nutritional status don't seem to be systematic. The aim of this study is to asses how relevant physicians consider Nutrition to be in the successful running of a good practice. The study was undertaken at the general hospital of Vila Real/Peso da Régua (CHVR/PR) by distribution of a self- administered questionnaire to 153 of the physicians of the clinical body. Mean values were compared with the Student's t test and proportions with the Chi-square test. Of the 153 physicians, 108 replies were received (70,6%). Of these 108 replies, 53,3% consider nutrition knowledge important although 29,6% state their knowledge is poor. More than half say that Clinical Nutrition should be a compulsory subject of the Medical Sciences syllabus, and 99,1% deem it important to assess the patient's nutritional status. About 95% stated they provided written or verbal nutritional guidance, and most of the physicians had already sought the assistance of a nutritionist. This study shows that the clinical body of the CHVR/PR is aware of the importance nutrition knowledge has in their daily practice. It must be noted, though, that although almost one third of the physicians rate their nutrition knowledge poor, most of them provide nutritional guidance to their patients.

    Resveratrol is a naturally occurring compound contributing to cellular defense mechanisms in plants. Its use as a nutritional component and/or supplement in a number of diseases, disorders, and syndromes such as chronic diseases of the central nervous system, cancer, inflammatory diseases, diabetes, and cardiovascular diseases has prompted great interest in the underlying molecular mechanisms of action. The present review focuses on resveratrol, specifically its isomer trans-resveratrol, and its effects on intracellular calcium signaling mechanisms. As resveratrol's mechanisms of action are likely pleiotropic, its effects and interactions with key signaling proteins controlling cellular calcium homeostasis are reviewed and discussed. The clinical relevance of resveratrol's actions on excitable cells, transformed or cancer cells, immune cells and retinal pigment epithelial cells are contrasted with a review of the molecular mechanisms affecting calcium signaling proteins on the plasma membrane, cytoplasm, endoplasmic reticulum, and mitochondria. The present review emphasizes the correlation between molecular mechanisms of action that have recently been identified for resveratrol and their clinical implications.

    Full Text Available Amyotrophic lateral sclerosis (ALS, characterized by the progressive loss of both upper and lower motor neurons, is a fatal neurodegenerative disorder. This disease is often accompanied by a tremendous physical and emotional burden not only for the patients, but also for their families and friends as well. There is no clinically relevant treatment available for ALS. To date, only one Food and Drug Administration (FDA-approved drug, Riluzole, licensed 18 years ago, has been proven to marginally prolong patients′ survival without improving the quality of their lives. Because of the lack of an effective drug treatment and the promising outcomes from several preclinical studies, researchers have highlighted this disease as a suitable candidate for stem cell therapy. This review article highlights the finding of key preclinical studies that present a rationale for the use of different types of stem cells for the treatment of ALS, and the most recent updates on the stem cell-based ALS clinical trials around the world.

    Full Text Available Introduction. Natural Killer cells (NK cells represent the subset of peripheral lymphocytes that play critical role in the innate immune response to virus-infected and tumor transformed cells. Lysis of NK sensitive target cells could be mediated independently of antigen stimulation and without requirement of peptide presentation by the major histocompatibility complex (MHC molecules. NK cell activity and functions are controlled by a considerable number of cell surface receptors, which exist in both inhibitory and activating isoforms. There are several groups of NK cell surface receptors: 1 killer immunoglobulin like receptors-KIR, 2 C-type lectin receptors,3natural citotoxicity receptors-NCR and 4 Toll-like receptors-TLR. Functions of NK receptors. Defining the biology of NK cell surface receptors has contributed to the concept of the manner how NK cells selectively recognize and lyse tumor and virally infected cells while sparing normal cells. Further, identification of NK receptor ligands and their expression on the normal and transformed cells has led to the development of clinical approaches to manipulating receptor/ligand interactions that showed clinical benefit. NK cells are the first lymphocyte subset that reconstitute the peripheral blood following allogeneic HSCT and multiple roles for alloreactive donor NK cells have been demonstrated, in diminishing Graft vs. Host Disease (GvHD through selective killing recipient dendritic cells, prevention of graft rejection by killing recipient T cells and participation in Graft vs. Leukaemia (GvL effect through destruction of residual host tumor cells. Conclusion. Besides their role in HSCT, NK cell receptors have an important clinical relevance that reflects from the fact that they play a crucial role in the development of some diseases as well as in possibilities of managing all NK receptors through selective expansion and usage of NK cells in cancer immunotherapy.

    Congenital factor, obesity, aging, pregnancy and childbirth are the main risk factors for female pelvic floor disorders (urinary incontinence, anal incontinence, pelvic organ prolapse, dyspareunia). Vaginal delivery may cause injury to the pudendal nerve, the anal sphincter, or the anal sphincter. However the link between these injuries and pelvic floor symptoms is not always determined and we still ignore what might be the ways of prevention. Of the many obstetrical methods proposed to prevent postpartum symptoms, episiotomy, delivery in vertical position, delayed pushing, perineal massage, warm pack, pelvic floor rehabilitation, results are disappointing or limited. Caesarean section is followed by less postnatal urinary incontinence than vaginal childbirth. However this difference tends to disappear with time and following childbirth. Limit the number of instrumental extractions and prefer the vacuum to forceps could reduce pelvic floor disorders after childbirth. Ultrasound examination of the anal sphincter after a second-degree perineal tear is useful to detect and repair infra-clinic anal sphincter lesions. Scientific data is insufficient to justify an elective cesarean section in order to avoid pelvic floor symptoms in a woman without previous disorders.

    Detrusor instability is the second most frequent cause of female urinary incontinence. There are many therapeutic options, including non-invasive and surgical procedures. In this study, we evaluated the effects of pelvic floor vaginal electrostimulation using equipment designed in our institution, over three consecutive months, for treatment of 29 women with detrusor instability. After treatment 22 patients (76%) considered themselves cured or symptomatically improved; seven patients (24%) had no change in symptoms after therapy. There was objective cure and improvement in ten (34.5%) and in eight (27.5%) patients, respectively, and the urodynamic parameters did not change in 11 patients (38%). Electrical stimulation resulted in a gradual decrease in the number of urinary leakage episodes and increase in maximum cystometric capacity in first desire to void and in urinary volume.

    In <10% of patients with prostatitis syndrome, a causative uropathogenic organism can be detected. It has been shown that certain organisms that cause sexually transmitted infections can also cause chronic bacterial prostatitis, which can be hard to diagnose and treat appropriately because prostatic samples obtained by prostatic massage are not routinely tested to detect them. We conducted a clinical study to determine the prevalence of Chlamydia, mycoplasma, and trichomonas infection in 254 patients that were previously diagnosed and treated for chronic prostatitis/chronic pelvic pain syndrome due to negative urethral swab, urine, and prostate samples. Urethral swabs and standard Meares-Stamey four-glass tests were done. Detailed microbiological analysis was conducted to detect the above organisms. Thirty-five (13.8%) patients had positive expressed prostatic secretions/VB3 samples, of which 22 (10.1%) were sexually transmitted organisms that were not detected on previous tests.

There is a lack of studies with good sample size that provide a comprehensive psychological profile of women presenting to specialist chronic pain clinics. Therefore, the objective of this study was to describe the psychological profile of a representative sample of women presenting with CPP at a tertiary referral center. Design: This was a cross-sectional study. Women were asked to complete a questionnaire assessing symptoms of anxiety and depression, pain severity and interference, pain self-efficacy and catastrophizing beliefs, and sexual functioning. Methods: One-hundred and seventy-five women with CPP were recruited when they attended their initial assessment at a specialist CPP clinic of the Royal Women’s Hospital, a public ­hospital in Melbourne, Australia. Results: Over 75% of the participants had experienced pain for longer than 2 years. Fifty-three percent of women experienced either moderate or severe anxiety, and 26.7% experienced moderate-to-severe depression. There were strong correlations between depressive symptoms and pain interference, pain catastrophizing and self-efficacy beliefs. Conclusion: Our findings confirm previous evidence for high levels of psychological distress and functional impairment associated with this condition, and extend these findings by including measures that are highly relevant to treatment planning, such as thinking styles and pain self-efficacy. Therefore, treatment of this complex condition needs to be holistic, and a multi

    To propose a clinical phenotype system (urinary, psychosocial, organ specific, infection, neurologic/systemic, and tenderness [UPOINT]) to classify patients with urologic pelvic pain to help understand the etiology and guide therapy. We wished to validate this system in men with chronic pelvic pain syndrome (CPPS). CPPS is a heterogeneous syndrome with a variable treatment response. A total of 90 men with CPPS were retrospectively classified in each domain of our UPOINT system and the symptoms were measured using the Chronic Prostatitis Symptom Index. The percentage of patients positive for each domain was 52%, 34%, 61%, 16%, 37%, and 53% for the urinary, psychosocial, organ specific, infection, neurologic/systemic, and tenderness domains, respectively. Of the 90 patients, 22% were positive for only 1 domain, and a significant stepwise increase was found in the total Chronic Prostatitis Symptom Index score as the number of positive domains increased. A symptom duration of >2 years was associated with an increase in positive domains (2.9 +/- 0.21 vs 2.3 +/- 0.14, P = .01). Comparing the total Chronic Prostatitis Symptom Index score with the presence of each domain revealed significantly increased symptoms in patients positive for the urinary, psychosocial, organ specific, and neurologic/systemic domains. When this analysis was repeated for the pain subscore, the psychosocial, neurologic/systemic, and tenderness domains had significantly greater scores. Only the psychosocial and neurologic domains influenced the patients' quality of life. Applying the UPOINT system to patients with CPPS can discriminate clinical phenotypes, allowing for hypothesis testing for etiology and therapy. The number of positive domains correlated with symptom severity and a longer duration of symptoms increased the number of positive domains. Because each domain has specific targeted therapies, we propose that multimodal therapy might best be guided by the UPOINT phenotype.

    Orthostatic hypotension (OH) is highly prevalent in old age. The impact of OH on orthostatic complaints and falling is questionable. We wondered if the consensus definition of OH plays an essential role in the accuracy and direction of the prediction of these endpoints. We aimed to explore the relation between different definitions of OH, including relative decrease of blood pressure, and orthostatic complaints and falling. A cross-sectional study was performed with 1415 participants aged ≥65 years visiting a mobile fall-prevention team. The CAREFALL Triage Instrument and data on blood pressure, orthostatic complaints and previous fall incidents were collected. Multivariate binary logistic regression analyses were performed to assess the association of different definitions of OH and orthostatic complaints or falling. Ten different definitions of OH based on different relative declines of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were defined. The 2011 consensus definition of OH was not related to orthostatic complaints (Odds Ratio (OR) 1.07 (95 % Confidence Interval (CI) 0.68-1.69)) or previous fall incidents (OR 1.08 (95%CI 0.83-1.41)). A ≥ 25 % SBP decrease was significantly related to orthostatic complaints (OR 2.81 (95%CI 1.31-6.05)) and a ≥ 25 % DBP decrease was related to previous fall incidents (OR 2.56 (95%CI 1.08-6.09)). With the exception of a decrease of ≥25 % SBP or DBP, the clinical relevance of incidental OH blood pressure measurements seems very limited with respect to orthostatic complaints or fall incidents in elderly patients. Using relative decreases may be more appropriate in clinical practice. Geriatr Gerontol Int 2016; ••: ••-••. © 2017 Japan Geriatrics Society.

    Sulindac is a non-selective inhibitor of cyclooxygenases (COX) used to treat inflammation and pain. Additionally, non-COX targets may account for the drug's chemo-preventive efficacy against colorectal cancer and reduced gastrointestinal toxicity. Here, we demonstrate that the pharmacologically active metabolite of sulindac, sulindac sulfide (SSi), targets 5-lipoxygenase (5-LO), the key enzyme in the biosynthesis of proinflammatory leukotrienes (LTs). SSi inhibited 5-LO in ionophore A23187- and LPS/fMLP-stimulated human polymorphonuclear leukocytes (IC(50) approximately 8-10 microM). Importantly, SSi efficiently suppressed 5-LO in human whole blood at clinically relevant plasma levels (IC(50) = 18.7 microM). SSi was 5-LO-selective as no inhibition of related lipoxygenases (12-LO, 15-LO) was observed. The sulindac prodrug and the other metabolite, sulindac sulfone (SSo), failed to inhibit 5-LO. Mechanistic analysis demonstrated that SSi directly suppresses 5-LO with an IC(50) of 20 muM. Together, these findings may provide a novel molecular basis to explain the COX-independent pharmacological effects of sulindac under therapy.

    Full Text Available The authors present their experience related to the diagnosis, treatment, and followup of 431 patients with bullous pemphigoid, 14 patients with juvenile bullous pemphigoid, and 273 patients with pemphigus. The detection of autoantibodies plays an outstanding role in the diagnosis and differential diagnosis. Paraneoplastic pemphigoid is suggested to be a distinct entity from the group of bullous pemphigoid in view of the linear C3 deposits along the basement membrane of the perilesional skin and the “ladder” configuration of autoantibodies demonstrated by western blot analysis. It is proposed that IgA pemphigoid should be differentiated from the linear IgA dermatoses. Immunosuppressive therapy is recommended in which the maintenance dose of corticosteroid is administered every second day, thereby reducing the side effects of the corticosteroids. Following the detection of IgA antibodies (IgA pemphigoid, linear IgA bullous dermatosis, and IgA pemphigus, diamino diphenyl sulfone (dapsone therapy is preferred alone or in combination. The clinical relevance of autoantibodies in patients with autoimmune bullous dermatosis is stressed.

    2013-01-01

    The main objective of this paper is to examine evidence for the concept that epileptic activity should be envisaged in terms of functional connectivity and dynamics of neuronal networks. Basic concepts regarding structure and dynamics of neuronal networks are briefly described. Particular attention is given to approaches that are derived, or related, to the concept of causality, as formulated by Granger. Linear and non-linear methodologies aiming at characterizing the dynamics of neuronal networks applied to EEG/MEG and combined EEG/fMRI signals in epilepsy are critically reviewed. The relevance of functional dynamical analysis of neuronal networks with respect to clinical queries in focal cortical dysplasias, temporal lobe epilepsies, and "generalized" epilepsies is emphasized. In the light of the concepts of epileptic neuronal networks, and recent experimental findings, the dichotomic classification in focal and generalized epilepsy is re-evaluated. It is proposed that so-called "generalized epilepsies," such as absence seizures, are actually fast spreading epilepsies, the onset of which can be tracked down to particular neuronal networks using appropriate network analysis. Finally new approaches to delineate epileptogenic networks are discussed.

    Pedicle subtraction osteotomy (PSO) is one of the surgical options for treating alignment disorders of the fused spine (due to post-surgical fusion or related to arthritis). It enables satisfactory sagittal realignment and improved function due to economic sagittal balance. The aim of this study was to analyze clinical and radiological results of PSO after a minimum follow-up of 2 years and demonstrate the benefit of sub-group analysis as a function of pelvic incidence (PI). A descriptive prospective single center study of 63 patients presenting with spinal global malalignment who underwent correction by PSO. Function was assessed by the Oswestry disability index (ODI), a visual analog scale of lumbar pain (VAS) and a SF-36 questionnaire. Radiographic analyses of pre- and post-operative pelvic-spinal parameters were performed on X-rays obtained by EOS(®) imaging after 3D modeling. Global analysis and analysis of sub-groups as a function of pelvic incidence were performed and the full balance integrated index (FBI) was calculated. this series showed a marked clinical improvement and significant progress of functional scores. Global post-operative radiological analysis showed a significant improvement in all pelvic and spinal parameters. The mean correction obtained after PSO was 31.7° ± 8.4°, hence global improvement of lumbar lordosis of 22°. The sagittal vertical angle (SVA) decreased from +9 cm before surgery to +4.3 cm after surgery. Sub-group analysis demonstrated greater improvement in pelvic tilt, sacral slope and spinal parameters of patients with a small or moderate pelvic incidence; all had an FBI index 10° PSO is a surgical procedure enabling correction of multiplane rigid spinal deformities that require major sagittal correction. It was seen to be highly effective in patients with a small or moderate pelvic incidence (PI <60°) but was sometimes less effective in patients with large pelvic incidence due to insufficient lordosis correction

    Our objective was to measure the sagittal plane rotational (flexion and extension) displacement of hemipelvis radiologically and analyze the ratio of flexion and extension displacement of unstable pelvic fractures. We used 8 cadaveric models to study the radiographic evidence of pelvic fractures in the sagittal plane. We performed pelvic osteotomy on 8 cadavers to simulate anterior and posterior pelvic ring injury. Radiological data were measured in the flexion and extension group under different angles (5°, 10°, 15°, 20°, and 25°). We retrospectively reviewed 164 patients who were diagnosed with a unilateral fracture of the pelvis. Pelvic ring displacement was identified and recorded radiographically in cadaveric models. The flexion and extension displacement of pelvic fractures was measured in terms of the vertical distance of fracture from the top of iliac crest to the pubic tubercle (CD) or from the top of iliac crest to the lowest point of ischial tuberosity (AB). Fifty-seven pelves showed flexion displacement and 15 showed extension displacement. Closed reduction including internal fixation and external fixation was successfully used in 141 cases (86.0 %). The success rates of closed reduction in flexion and extension displacement groups were 77 and 73 %, respectively, which were lower than in unstable pelvic ring fractures. The sagittal plane rotation (flexion and extension) displacement of pelvic fractures could be measured by special points and lines on the radiographs. Minimally invasive reduction should be based on clearly identified differences between the sagittal plane rotation and the vertical displacement of pelvic fractures.

    PurposeThis study was designed to evaluate the clinical outcome and patients' satisfaction after a 5 year follow-up period for pelvic congestion syndrome (PCS) coil embolization in patients who suffered from chronic pelvic pain that initially consulted for lower limb venous insufficiency.MethodsA total of 202 patients suffering from chronic pelvic pain were recruited prospectively in a single center (mean age 43.5 years; range 27-57) where they were being treated for lower limb varices. Inclusion criteria were: lower limb varices and chronic pelvic pain (>6 months), >6 mm pelvic venous caliber in ultrasonography, and venous reflux or presence of communicating veins. Both ovarian and hypogastric veins were targeted for embolization. Pain level was assessed before and after embolotherapy and during follow-up using a visual analog scale (VAS). Technical and clinical success and recurrence of leg varices were studied. Patients completed a quality questionnaire. Clinical follow-up was performed at 1, 3, and 6 months and every year for 5 years.ResultsTechnical success was 100 %. Clinical success was achieved in 168 patients (93.85 %), with complete disappearance of symptoms in 60 patients (33.52 %). Pain score (VAS) was 7.34 {+-} 0.7 preprocedural versus 0.78 {+-} 1.2 at the end of follow-up (P < 0.0001). Complications were: groin hematoma (n = 6), coil migration (n = 4), and reaction to contrast media (n = 1). Twenty-three cases presented abdominal pain after procedure. In 24 patients (12.5 %), there was recurrence of their leg varices within the follow-up. The mean degree of patients' satisfaction was 7.4/9.ConclusionsCoil embolization of PCS is an effective and safe procedure, with high clinical success rate and degree of satisfaction.

    The anterior pelvic exenteration is technically demanding surgical intervention carried out in advanced malignant genito-urethral process origin. It is characterized by a high percentage of intra and postoperative complications. They can be reduced through new surgical techniques, such as extra peritoneal approach to perform this operation. We present a clinical case of 56 years old patient with adenocarcinoma of the urethra/bladder established histologically by TUR (Transurethral) - biopsy. Of the clinical and imaging studies - data for the invasion to the anterior vaginal wall. The patient is after Total Hysterectomy with bilateral salpingo oophorectomy on the occasion of the fibroids in the uterus. After a routine preoperative preparation, we did: extra peritoneal anterior pelvic exenteration with total urethrectomy and vaginectomy. Bilateral extra peritoneal ureterocutaneostomy with "JJ" stents. Bilateral extra peritoneal pelvic lymph dissection. Our clinical case, proves the thesis of many authors about the benefits of extra peritoneal approach for anterior pelvic exenteration. Reduce significantly the intra/post-operative complications, hospital stay and a time to follow postoperative therapy. We consider that the extra peritoneal approach for radical surgery should be applied whenever possible in the interest of the health of the patient.

    Pelvic actinomycosis is a rare chronic infection caused by bacteria of the family Actinomycetaceae. Prolonged use of an intrauterine contraceptive device (IUD) is a well known risk factor. We report six patients with pelvic actinomycosis, all of whom had an IUD inserted for over six years. Diagnostic problems necessitated a laparotomy in all patients. The pathohistological diagnosis was based on the characteristic microscopic image and specific staining. The patients were treated with penicillin and amoxycillin for several months.

    Full Text Available Objective: To compare the efficacy of ceftriaxone plus Ofloxacin or Azithromycin for cases of pelvic inflammatory disease (PID.Materials and Methods:  This clinical terial was performed on 180 women with PID from March 2005 to March 2007 in Parastarane-Shahed Hospital. Patients with PID were randomly divided to receive injection of Ceftriaxone 250 mg plus Ofloxacin 200 mg per day or Azithromycin 1 g per week for two weeks (90 cases in each group. The degree of pain was assessed on days 7, 14, 30 and clinical cure was assessed on days 14 and 30. Statistical analysis was done based on Fisher exact test, Mann-Whitny and student t-test.Results: From 180 patients eligible for the study, 138 cases were enrolled for protocol analysis. Significant differences were observed regarding the degree of pain between two groups. Clinical cure was 90% (70 of 78 for Azithromycin and 83.3% (50 of 60 for Ofloxacin. Conclusion: Combination of Ceftriaxone plus weekly Azithromycin for two weeks is not only equivalent to Ceftriaxone plus daily Ofloxacin for two weeks but also seems to be better for the treatment of mild PID.

    Pelvic floor muscle exercises have been recommended for urinary incontinence since first described by obstetrician gynecologist Dr. Arnold Kegel more than six decades ago. These exercises are performed to strengthen pelvic floor muscles, provide urethral support to prevent urine leakage, and suppress urgency. In clinical urology practice, expert clinicians also teach patients how to relax the muscle to improve bladder emptying and relieve pelvic pain caused by muscle spasm. When treating lower urinary tract symptoms, an exercise training program combined with biofeedback therapy has been recommended as first-line treatment. This article provides clinical application of pelvic floor muscle rehabilitation using biofeedback as a technique to enhance pelvic floor muscle training.

    Our objective was to compare survival and complication rates of horses undergoing pelvic flexure enterotomy closure with a TA-90 stapler to those with hand-sewn closure. Medical records of horses undergoing pelvic flexure enterotomy between 2001 and 2008 were reviewed. History, clinical signs, surgical findings, surgical techniques, and post-operative complications were recorded. Long-term outcome was established by telephone questionnaire. Of 84 pelvic flexure enterotomies performed, 70 were stapled and 14 were hand-sewn. Seventy-seven horses survived to discharge (91.7%). There were no significant associations between survival and closure technique (P = 0.69). Follow-up was available for 54 horses; 50 survived long-term (93.0%). No statistical significance was identified between long-term survival and closure method (P = 0.39). Forty horses went on to athletic performance (80.0%). TA-90 stapled closure of pelvic flexure enterotomies is a safe technique resulting in survival and complication rates equivalent to those of hand-sewn closure.

    2016-01-01

    Objective Chronic pelvic pain (CPP) is widely acknowledged as a common problem with significant consequences for those diagnosed with this condition. There is a lack of studies with good sample size that provide a comprehensive psychological profile of women presenting to specialist chronic pain clinics. Therefore, the objective of this study was to describe the psychological profile of a representative sample of women presenting with CPP at a tertiary referral center. Design This was a cross-sectional study. Women were asked to complete a questionnaire assessing symptoms of anxiety and depression, pain severity and interference, pain self-efficacy and catastrophizing beliefs, and sexual functioning. Methods One-hundred and seventy-five women with CPP were recruited when they attended their initial assessment at a specialist CPP clinic of the Royal Women’s Hospital, a public hospital in Melbourne, Australia. Results Over 75% of the participants had experienced pain for longer than 2 years. Fifty-three percent of women experienced either moderate or severe anxiety, and 26.7% experienced moderate-to-severe depression. There were strong correlations between depressive symptoms and pain interference, pain catastrophizing and self-efficacy beliefs. Conclusion Our findings confirm previous evidence for high levels of psychological distress and functional impairment associated with this condition, and extend these findings by including measures that are highly relevant to treatment planning, such as thinking styles and pain self-efficacy. Therefore, treatment of this complex condition needs to be holistic, and a multidisciplinary approach is likely to be the best way to achieve this. PMID:27895510

  12. Evidence-Based Clinical Significance in Health Care: Toward an Inferential Analysis of Clinical Relevance

    Full Text Available Evidence-based dental practice requires the developmment and evaluation of protocols that en-sure translational effectiveness: that is, the efficient incorporation of the best available efficacy and effec-tiveness findings in specific clinical dentistry settings and environments. Evidence-based dentistry predi-cates the synthesis of research for obtaining the best available evidence in a validated, stringent, systematic and unbiased fashion. Research synthesis is now established as a science in its own right, precisely because it adheres to the scientific process that is driven by a research question and a hypothesis, follows through clearly defined methodology and design, yielding quantifiable data that are analyzed statistically, and from which stringent statistical inferences are drawn. The conclusions from the protocol of research synthesis define the best available evidence, which is used in the process of evidence-based revision of clinical practice guidelines. One important hurdle of the process of applying research synthesis in evidence-based dentistry lies in the fact that the statistical inferences produced by research must be translated into clinical relevance. Here, we present a model to circumvent this limitation by means of text analysis/mining protocols, which could lead the path toward a novel, valid and reliable ap-proach for the inferential analysis of clinical relevance.

    Incomplete history and concern for occult injury in suspected child abuse occasionally results in CT screenings of the abdomen and pelvis. At our institution, we noted that these exams were infrequently positive. To identify clinical or laboratory criteria that may predict intra-abdominal injury and guide the use of abdominal and pelvic CT in this population. This retrospective review involved 68 children older than 36 months who had a CT of the abdomen/pelvis for suspected abuse. CT results and patient charts were reviewed for physical exam and historical and laboratory variables. CTs were positive in 16% of patients (11/68). Hypoactive/absent bowel sounds (P = 0.01, specificity = 94.7%) and AST and ALT values greater than twice normal (P = 0.004 and P = 0.003 respectively, NPV = 93.6%) were significantly associated with positive CTs. Multiple abnormal physical exam or laboratory findings were also significantly associated with positive CTs (P = 0.03 and P = 0.002 respectively, specificity = 91.3% and NPV = 93.6% respectively). CTs of the abdomen and pelvis are infrequently positive in cases of suspected abuse. To reduce radiation exposure, CTs should only be ordered if there are findings indicating that they may be positive. In our population, these findings include absent/hypoactive bowel sounds, LFTs greater than twice normal and {>=}2 abnormal labs or physical exam findings. (orig.)

    To compare the acupuncture treatment and the medical treatment with antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs) on pain control, urinary symptoms, and quality of life of category IIIB chronic prostatitis-chronic pelvic pain syndrome (CP-CPPS). From November 2008 to May 2009, 54 male patients with category IIIB CP-CPPS were randomly divided into 2 groups: the medical treatment group (group 1, n = 28) and the acupuncture treatment group (group 2, n = 26). Group 1 took levofloxacin 500 mg daily and ibuprofen 200 mg twice a day for 6 weeks. In the acupuncture group (group 2), bilateral BL32 (Ciliao) and BL33 (Zhongliao) acupoints were used to stimulate the sacral nerve using an electrical pulse generator, twice a week for 7 weeks. The change in National Institutes of Health Chronic Prostatitis Symptom Index scores from the baseline to the end of the treatment was observed. The mean follow-up was 28 weeks from the baseline (range, 20-43 weeks). In acupuncture group, reduction of pain, urinary symptoms, quality of life, and total National Institutes of Health Chronic Prostatitis Symptom Index score was higher compared with the medical group. However the treatment of CP-CPPS is challenging and difficult for the urologists. This clinical study showed that the acupuncture treatment is a safe and effective treatment of category IIIB CP-CPPS.

    Determine how varying longitudinal historical training data can impact prediction of future clinical decisions. Estimate the "decay rate" of clinical data source relevance. We trained a clinical order recommender system, analogous to Netflix or Amazon's "Customers who bought A also bought B..." product recommenders, based on a tertiary academic hospital's structured electronic health record data. We used this system to predict future (2013) admission orders based on different subsets of historical training data (2009 through 2012), relative to existing human-authored order sets. Predicting future (2013) inpatient orders is more accurate with models trained on just one month of recent (2012) data than with 12 months of older (2009) data (ROC AUC 0.91 vs. 0.88, precision 27% vs. 22%, recall 52% vs. 43%, all P<10(-10)). Algorithmically learned models from even the older (2009) data was still more effective than existing human-authored order sets (ROC AUC 0.81, precision 16% recall 35%). Training with more longitudinal data (2009-2012) was no better than using only the most recent (2012) data, unless applying a decaying weighting scheme with a "half-life" of data relevance about 4 months. Clinical practice patterns (automatically) learned from electronic health record data can vary substantially across years. Gold standards for clinical decision support are elusive moving targets, reinforcing the need for automated methods that can adapt to evolving information. Prioritizing small amounts of recent data is more effective than using larger amounts of older data towards future clinical predictions. Copyright © 2017 The Authors. Published by Elsevier B.V.

    Sørensen, Jakob; Sjøgren, Per

    2011-03-28

    Opioids are widely used as analgesics in chronic pain of malignant as well as non-malignant origin. During opioid treatment, pain is occasionally worsened. This could be due to progression of the disease or tolerance or opioid-induced hyperalgesia (OIH). The present article summarizes the preclinical and clinical data in support of the existence of OIH. Further, possible mechanisms and potential treatments are outlined. We conclude that only a few clinical studies on OIH are available. However, a growing body of experimental data supports the presence of OIH in clinical settings. Diagnostic tools for assessment of OIH have yet to be developed.

    Full Text Available Abstract Background For the moment, scientific evaluation of programs on treatment of pregnancy-related pelvic girdle and/or low back pain after delivery is hardly available with only one study with a positive result, suggesting uncertainty about the optimal approach. Investigators draw particular attention to biomedical factors but there is growing evidence that biopsychosocial factors appear to be even more important as a basis of an intervention program. Methods We studied the effectiveness of a tailor-made program with respect to biopsychosocial factors (intervention group in women with pregnancy-related pelvic girdle and/ or low back pain versus usual care based on a pain contingent basis (control group shortly after delivery in a randomized controlled trial. Women with severe complaints shortly after delivery were selected from a longitudinal prospective cohort study (n = 7526, aimed at pregnancy-related pelvic girdle and/or low back pain in the Netherlands. A concealed block randomization was performed after collecting baseline data. Researchers were blinded to treatment assignment. Outcomes were evaluated within the domains of the biopsychosocial approach. Primary outcome concerned limitations in activities (RDQ. Follow-up measurements were performed 12 weeks after delivery. Results Since May 2001 until July 2003, 869 women out of the cohort made a request for treatment by a physiotherapist, 10 days after delivery. Because of a quick recovery in two weeks time, we included only 126 women three weeks after delivery. There was a statistically significant and clinically relevant difference in improvement on the primary outcome (RDQ between the two groups in favor of the experimental intervention. Conclusion The results favored the hypotheses. Women's worries about their condition were major targets in the experimental intervention. The prognosis after delivery, especially in de first weeks, turned out to be favorable.

  19. Post Pelvic Radiotherapy Bony Changes

    There has been recent interest in radiation-induced bone injury in clinical conditions, especially for pelvic insufficiency fracture (PIF). A PIF is caused by the effect of normal or physiological stress on bone with demineralization and decreased elastic resistance. Pelvic radiotherapy (RT) can also contribute to the development of a PIF. A PIF has been regarded as a rare complication with the use of megavoltage equipment. However, recent studies have reported the incidence of PIFs as 8.2{approx}20% after pelvic RT in gynecological patients, an incidence that was higher than previously believed. The importance of understanding a PIF lies in the potential for misdiagnosis as a bony metastasis. If patients complain of pelvic pain after whole-pelvis radiation therapy, the presence of a PIF must be considered in the differential diagnosis. The use of multibeam arrangements and conformal RT to reduce the volume and dose of irradiated pelvic bone can be helpful to minimize the risk of fracture. In addition to a PIF, osteonecrosis and avascular necrosis of the femoral head can develop after radiation therapy. Osteoradionecrosis of the pelvic bone is a clinical diagnostic challenge that must be differentiated from an osseous metastasis. A post-radiation bone sarcoma can result as a long-term sequela of pelvic irradiation for uterine cervical cancer.

  20. Opioid-induced hyperalgesia: clinically relevant or extraneous research phenomenon?

    Science.gov (United States)

    Tompkins, D Andrew; Campbell, Claudia M

    2011-04-01

    Opioids have become the unequivocal therapy of choice in treating many varieties of chronic pain. With the increased prescription of opioids, some unintended consequences have occurred. After prolonged opioid exposure, opioid-induced hyperalgesia (OIH), the paradoxical effect that opioid therapy may in fact enhance or aggravate preexisting pain, may occur. Over the past several decades, an increasing number of laboratory and clinical reports have suggested lowered pain thresholds and heightened atypical pain unrelated to the original perceived pain sensations as hallmarks of OIH. However, not all evidence supports the clinical importance of OIH, and some question whether the phenomenon exists at all. Here, we present a nonexhaustive, brief review of the recent literature. OIH will be reviewed in terms of preclinical and clinical evidence for and against its existence; recommendations for clinical evaluation and intervention also will be discussed.

    The clinical relevance of the host immune system in breast cancer has long been unexplored. Studies developed over the past decade have highlighted the biological heterogeneity of breast cancer, prompting researchers to investigate whether the role of the immune system in this malignancy is similar across different molecular subtypes of the disease. The presence of high levels of lymphocytic infiltration has been consistently associated with a more-favourable prognosis in patients with early stage triple-negative and HER2-positive breast cancer. These infiltrates seem to reflect favourable host antitumour immune responses, suggesting that immune activation is important for improving survival outcomes. In this Review, we discuss the composition of the immune infiltrates observed in breast cancers, as well as data supporting the clinical relevance of host antitumour immunity, as represented by lymphocytic infiltration, and how this biomarker could be used in the clinical setting. We also discuss the rationale for enhancing immunity in breast cancer, including early data on the efficacy of T-cell checkpoint inhibition in this setting.

    This study aimed to evaluate the relationship between the degree of perihepatitis and the severity of pelvic inflammatory disease (PID) on multidetector computed tomography (MDCT). A total of 177 women with PID who underwent biphasic abdominal computed tomography (CT) scans were enrolled. Two reviewers retrospectively reviewed the CT scans with consensus and subjectively categorized the severity of PID into 4 grades (normal, mild, moderate, and severe). Another reviewer independently assigned the extent (grades 0 to 4) and the depth (grades 0 to 4) of hepatic surface enhancement in terms of the degree of perihepatitis. Relationships between the degree of perihepatitis and the CT severity as well as each CT manifestation of PID were evaluated using the χ test or a cumulative logistic regression analysis. Of the 177 patients, 99 (55.9%) showed hepatic surface enhancement. The severity of PID on MDCT was significantly related with the degree of perihepatitis (all P pelvic fat haziness, complicated ascites, and omental/mesenteric fat infiltration were significantly related with the degree of perihepatitis (all P < 0.05). Among these variables, omental/mesenteric fat infiltration (odds ratio = 10.9) and salpingitis (odds ratio = 6.0) were the CT manifestations that were most associated with the presence of perihepatitis in PID. The degree of perihepatitis seems to show a relationship with the severity of PID on MDCT. Omental/mesenteric fat infiltration and salpingitis can be strongly related with perihepatitis in PID.

    The extensor pollicis longus (EPL) is a consistent structure with rare anomalies, the most common being a group of different tendon duplications passing through the fourth compartment without symptoms. The second form comprises anomalies in the course of the EPL having significant clinical importance due to the predisposition for creating tenosynovitis of the EPL mimicking other types of tendon tenosynovitis. Clinical symptoms of radial dorsal wrist pain mimicking intersection syndrome or de-Quervain disease with the "absent snuff box" sign should raise suspicions for an anomaly in the course of the EPL.

    Full Text Available PURPOSE: Actinomycosis is a chronic granulomatous infection caused by the gram-positive anaerobic bacteria, Actinomyces israelli. This paper reviews the etiology and clinical presentation associated with Actinomycosis that often presents as a pelvic mass that mimics a pelvic malignancy. MATERIALS AND METHODS: A combination of patients treated by the authors in the recent past and a literature review of patients with pelvic Actinomycosis were assessed for diographic, clinical and predisposing co-factors. An analysis is made of age distribution, gender, diagnostic methods and treatment concepts. RESULTS: Thirty-three patients were included in the study that included 2 current patients and 31 obtained from literature review. There were 27 fiales (age range 16 - 69 years, mean 38 years and 6 males (16 - 55 years, mean 36 years. Presenting signs and symptoms were lower abdominal mass in 28 (85%; lower abdominal pain in 21 (63%; vaginal discharge or hiaturia in 7 (22%. Two patients developed fistulae (entero-vesico 1; vesico-cutaneous 1. Nineteen (70% of the 27 fiale patients had intra-uterine contraceptive devices (IUD. Four patients (12.5% (3 males and 1 fiale had urachus or urachal rinants. Cystoscopy in 12 patients noted an extrinsic mass effect, bullous edia and in one patient vegetative proliferation proven to be a chronic inflammatory change. Exploratory laparotomy was performed in 32 of the 33 patients who had excision of mass and involved organs. Diagnosis was established by histologic examination of rioved tissue. Penicillin (6 weeks therapy was utilized to control infections. CONCLUSION: Pelvic actinomycosis mimics pelvic malignancy and may be associated with the long-term use of intra-uterine contraceptive devices, and persistent urachal rinants. Rioval of infected mass and antibiotic therapy will eradicate the inflammatory process.

    The study aimed to determine the fungal diversity in clinical waste samples from a healthcare facility in Penang Malaysia. Different fungi species were detected in 83.75 % of the 92 clinical waste samples that were screened from different sections of the healthcare facility. One hundred fifty fungal isolates comprising of 8 genera and 36 species were obtained. They were purified by using single spore isolation technique. Subsequently, the isolates were identified by phenotypic method based on morphological and culture characteristics on different culture media. Among all fungal isolates, Aspergillus spp. in section Nigri 10.2 %, Aspergillus niger 9.5 %, Aspergillus fumigatus 8.8 %, Penicillium. simplicissium 8 %, Aspergillus tubingensis 7.3 %, Aspergillus terreus var. terreus 6.6 %, Penicillium waksmanii 5.9 % and Curvularia lunata 6.5 % were the most frequent. Among five sections of the Wellness Centre, the clinical wastes collected from the diagnostic labs of haematology section had the highest numbers of fungal species (29 species). Glove wastes had the highest numbers of fungal species (19 species) among 17 types of clinical wastes screened. Among all fungal species, Aspergillus spp. exhibited higher growth at 37 °C than at 28 °C, indicating the potential of these opportunistic fungi to cause diseases in human.

    We aimed to compare the presentation, management, and clinical course in patients with perimesencephalic and nonperimesencephalic (aneurysmal) bleeding patterns on noncontrast CT, but negative initial 4-vessel digital subtraction angiography (DSA). We retrospectively reviewed clinical and imaging data for 280 patients presenting with spontaneous SAH admitted between 2005 and 2011. We identified 56 patients (20%) with SAH diagnosed on high resolution head CT performed within 48 hours of admission, and negative initial DSA, and divided them into perimesencephalic and non-perimesencephalic groups based on hemorrhage patterns. Patients with traumatic subarachnoid bleeding and those with initial positive DSA were excluded from this analysis. Perimesencephalic SAH was seen in 25 patients (45%); non-perimesencephalic bleeding patterns were seen in 31 (55%). All patients with perimesencephalic SAH presented with Hunt and Hess (HH) I, versus 45% HH I and 55% HH II-IV in those with non-perimecenphalic SAH. All patients with perimesencephalic SAH achieved modified Rankin score (mRS) 0 at discharge and 6-month follow-up, compared with 45% mRS 0 at discharge and 68% at 6-month follow-up in non-perimesencephalic SAH. Patients with perimesencephalic SAH presented a uniformly uncomplicated clinical course. Among non-perimesencephalic SAH patients there were 19 neurological/neurosurgical and 10 medical complications, two small aneurysms diagnosed at follow-up DSA, and one death. In this series, perimesencephalic SAH was associated with good clinical grades, consistently negative initial and follow-up angiograms, and an excellent prognosis. In contrast, non-perimesencephalic SAH was associated with a worse clinical presentation, higher complication rates, higher rates of true aneurysm detection on follow-up angiogram, and a poorer outcome.

    2011-12-29

    Abstract Sustainable research capacity building requires training individuals at multiple levels within a supportive institutional infrastructure to develop a critical mass of independent researchers. At many African medical institutions, a PhD is important for academic promotion and is, therefore, an important focal area for capacity building programs. We examine the training at the Infectious Diseases Institute (IDI) as a model for in-country training based on systems capacity building and attention to the academic environment. PhD training in Africa should provide a strong research foundation for individuals to perform independent, original research and to mentor others. Training the next generation of researchers within excellent indigenous academic centers of excellence with strong institutional infrastructure will empower trainees to ask regionally relevant research questions that will benefit Africans.

    When we look at the difference between two therapies or the association of a risk factor or prognostic indicator with its outcome, we need to evaluate the accuracy of the result. This assessment is based on a judgment that uses information about the study design and statistical management of the information. This paper specifically mentions the relevance of the statistical test selected. Statistical tests are chosen mainly from two characteristics: the objective of the study and type of variables. The objective can be divided into three test groups: a) those in which you want to show differences between groups or inside a group before and after a maneuver, b) those that seek to show the relationship (correlation) between variables, and c) those that aim to predict an outcome. The types of variables are divided in two: quantitative (continuous and discontinuous) and qualitative (ordinal and dichotomous). For example, if we seek to demonstrate differences in age (quantitative variable) among patients with systemic lupus erythematosus (SLE) with and without neurological disease (two groups), the appropriate test is the "Student t test for independent samples." But if the comparison is about the frequency of females (binomial variable), then the appropriate statistical test is the χ(2).

    Collado, Luis; Figueras, Maria José

    2011-01-01

    Summary: The genus Arcobacter, defined almost 20 years ago from members of the genus Campylobacter, has become increasingly important because its members are being considered emergent enteropathogens and/or potential zoonotic agents. Over recent years information that is relevant for microbiologists, especially those working in the medical and veterinary fields and in the food safety sector, has accumulated. Recently, the genus has been enlarged with several new species. The complete genomes of Arcobacter butzleri and Arcobacter nitrofigilis are available, with the former revealing diverse pathways characteristic of free-living microbes and virulence genes homologous to those of Campylobacter. The first multilocus sequence typing analysis showed a great diversity of sequence types, with no association with specific hosts or geographical regions. Advances in detection and identification techniques, mostly based on molecular methods, have been made. These microbes have been associated with water outbreaks and with indicators of fecal pollution, with food products and water as the suspected routes of transmission. This review updates this knowledge and provides the most recent data on the taxonomy, species diversity, methods of detection, and identification of these microbes as well as on their virulence potential and implication in human and animal diseases.

    2010-01-01

    Full Text Available Introduction Natural Killer cells (NK cells represent the subset of peripheral lymphocytes that play critical role in the innate immune response to virus-infected and tumor transformed cells. Lysis of NK sensitived target cells could be mediated independently of antigen stimulation, and unlike cytotoxic T-lymphocytes, they do not require peptide presentation by the major histocompatibility complex (MHC molecules. NK cell cytotoxic activity is controlled by considerable number of cell surface Killer cell Immunoglobulin like Receptors (KIRs, which can exist in both inhibitory and activating isoforms. The inhibitory KIRs are mostly specific for HLA class I ligands and I HLA class like molecules, while the specificity of activating receptors is regarded to lectine-like superfamily. The role of NK cells in allogeneic haematopoietic stem cell transplantation (HSCT: NK cells are the first lymphocyte subset that reconstitute the peripheral blood following allogeneic HSCT. By selecting donors mismatched for relevant HLA ligands in the context of recipients KIR genotype, multiple roles for alloreactive donor NK cells have been demonstrated, in diminishing Graft vs. Host Disease (GvHD through selective killing of recipient dendritic cells, prevention of graft rejection by killing recipient T cells and participation in Graft vs. Leukaemia (GvL effect through destruction of residual host tumor cells. Conclusion Investigation of KIRs heterogenity play an important role in the field of HSCT, because it is useful for the early diagnosis of post transplant complications and can serve as a predictive risk factor for GvHD development.

    The lack of effective conventional therapies for the treatment of advanced stage melanoma has stimulated interest in the development of novel strategies for the management of patients with malignant melanoma. Among them, immunotherapy has attracted much attention because of the potential role played by immunological events in the clinical course of melanoma. For many years, T cell-based immunotherapy has been emphasized in part because of the disappointing results of the monoclonal antibody (mAb)-based clinical trials conducted in the early 1980s and in part because of the postulated major role played by T cells in tumor growth control. More recently, mAb-based therapies have gained in popularity given their clinical and commercial success for a variety of malignant diseases. As a result, there has been increased interest in identifying and characterizing antibody-defined melanoma antigens. Among them, the chondroitin sulfate proteoglycan 4 (CSPG4), also known as high molecular weight-melanoma associated antigen (HMW-MAA) or melanoma chondroitin sulfate proteoglycan (MCSP), has attracted much attention in recent years because of the growing experimental evidence that it fulfills two requirements for immunotherapy to be therapeutically effective: (1) targeting of cancer stem cells (CSC) and (2) development of combinatorial therapies to counteract the escape mechanisms driven by the genetic instability of tumor cells. With this in mind, in this chapter, we have reviewed recent information related to the distribution of CSPG4 on various types of tumors, including CSC, its expression on pericytes in the tumor microenvironment, its recognition by T cells, its role in cell biology as well as the potential mechanisms underlying the ability of CSPG4-specific immunity to control malignant cell growth.

    The implantable cardioverter-defibrillator (ICD) has established itself as life-saving therapy in patients at risk for sudden cardiac death. Remarkable technological advances have made ICDs easier and safer to implant, with improved therapeutic and diagnostic functions and reduced morbidity. Guidelines on ICD indications have been proposed by American and European scientific societies since a number of years, based upon trials and expert opinion. In the context of variable economic and political constraints, it is questionable whether these guidelines may be applied to all settings. This review discusses the guideline-based indications, critically examines their applicability to clinical practice, and discusses alternatives to ICD therapy.

  2. Thyroid Autoantibodies in Pregnancy: Their Role, Regulation and Clinical Relevance

    Full Text Available Autoantibodies to thyroglobulin and thyroid peroxidase are common in the euthyroid population and are considered secondary responses and indicative of thyroid inflammation. By contrast, autoantibodies to the TSH receptor are unique to patients with Graves' disease and to some patients with Hashimoto's thyroiditis. Both types of thyroid antibodies are useful clinical markers of autoimmune thyroid disease and are profoundly influenced by the immune suppression of pregnancy and the resulting loss of such suppression in the postpartum period. Here, we review these three types of thyroid antibodies and their antigens and how they relate to pregnancy itself, obstetric and neonatal outcomes, and the postpartum.

    Frailty is a clinical syndrome that is increasingly prevalent during aging. Frailty involves the confluence of reduced strength, speed, physical activity, and endurance and is associated with adverse health outcomes. The present study adapts existing clinical and preclinical indices of frailty to the Fischer (F344) rat. Male F344 rats (n = 133; 17 mo) completed a battery of behavioral tasks, including forelimb wire suspension (strength), rotarod (speed), open field (physical activity), and inclined screen (endurance). Rats that performed poorly (lowest quintile) on two tasks were considered mildly frail (17.29%, n = 23), and rats that performed poorly on 3-4 tasks were considered frail (2.26%, n = 3). Logistic regression of 100-day survival revealed that mildly frail rats were 3.8 times and frail rats were 27.5 times more likely to die during that period than nonfrail rats (p = .038; 95% confidence interval: 2.030, 372.564). The selected criterion tests, cutoff points, and index provide a potential tool for identifying frailty in aged F344 rats, which is consistent with existing frailty indices for humans and mice.

    Koppert, W

    2004-05-01

    Opioids are the drugs of choice for the treatment of moderate to severe acute and chronic pain. However, clinical evidence suggests that opioids can elicit increased sensitivity to noxious stimuli suggesting that administration of opioids can activate both pain inhibitory and pain facilitatory systems. Acute receptor desensitization via uncoupling of the receptor from G-proteins, up-regulation of the cAMP pathway, activation of the N-methyl-D-aspartate (NMDA) receptor system, as well as descending facilitation, have been proposed as potential mechanisms underlying opioid-induced hyperalgesia. Numerous reports exist demonstrating that opioid-induced hyperalgesia is observed both in animal and human experimental models. Brief exposures to micro-receptor agonists induce long-lasting hyperalgesic effects for days, which might by reflected by clinical observations that large doses of intraoperative micro-receptor agonists increased postoperative pain and morphine consumption. Furthermore, the prolonged use of opioids in patients often requires increasing doses and may be accompanied by the development of abnormal pain. Successful strategies that may decrease or prevent opioid-induced hyperalgesia include the concomitant administration of drugs like NMDA-antagonists, alpha(2)-agonists, or non-steroidal anti-inflammatory drugs (NSAIDs), opioid rotation or combinations of opioids with different receptor selectivity.

  5. Update on Eosinophilic Meningoencephalitis and Its Clinical Relevance

    2009-01-01

    Summary: Eosinophilic meningoencephalitis is caused by a variety of helminthic infections. These worm-specific infections are named after the causative worm genera, the most common being angiostrongyliasis, gnathostomiasis, toxocariasis, cysticercosis, schistosomiasis, baylisascariasis, and paragonimiasis. Worm parasites enter an organism through ingestion of contaminated water or an intermediate host and can eventually affect the central nervous system (CNS). These infections are potentially serious events leading to sequelae or death, and diagnosis depends on currently limited molecular methods. Identification of parasites in fluids and tissues is rarely possible, while images and clinical examinations do not lead to a definitive diagnosis. Treatment usually requires the concomitant administration of corticoids and anthelminthic drugs, yet new compounds and their extensive and detailed clinical evaluation are much needed. Eosinophilia in fluids may be detected in other infectious and noninfectious conditions, such as neoplastic disease, drug use, and prosthesis reactions. Thus, distinctive identification of eosinophils in fluids is a necessary component in the etiologic diagnosis of CNS infections. PMID:19366917

    We describe the pattern of sensitisation to pet IgE components and its association with clinical symptoms. Hundred and fifty nine consecutive patients with rhinitis/asthma sensitised to dog, cat, and horse were recruited. Specific IgE to whole extracts and to pet recombinant allergens were performed. Only 5% of patients were monosensitised to animal allergens. Specific IgE to Can f 1 was significantly associated with persistent rhinitis, Can f 2 with asthma diagnosis, Can f 3 with moderate/severe rhinitis (M/S-R) and asthma diagnosis (AD), and Can f 5 with persistent and M/S-R. Positive IgE to Fel d 2 was significantly associated with M/S-R and AD, Equ c 1 with M/S-R and Equ c 3 with persistent rhinitis, AD and severe asthma. Sensitisation to ≥2 molecules or to pet albumins was associated with more severe respiratory symptoms. Molecular diagnosis in patients with pet allergy may also help clinicians to predict clinical symptoms and their severity.

    INTRODUCTION: Variation in shape, position and treatment response of both tumor and organs at risk are major challenges for accurate dose delivery in radiotherapy. Adaptive radiotherapy (ART) has been proposed to customize the treatment to these motion/response patterns of the individual patients......Med. For each tumor site, the identified papers were screened independently by two researches for selection of studies describing all processes of an ART workflow: treatment monitoring and evaluation, decision and execution of adaptations. Both brachytherapy and external beam studies were eligible for review....... RESULTS: The review consisted of 43 clinical studies and 51 in silico studies. For prostate, 1219 patients were treated with offline re-planning, mainly to adapt prostate motion relative to bony anatomy. For gyne 1155 patients were treated with online brachytherapy re-planning while 25 ano-rectal cancer...

    In oncology, early and individualized nutritional intervention for each patient is essential to improve nutritional intake and status, to reduce morbidity during treatment, enhance tolerance to treatment and improve Quality of Life. For medical students to evaluate nutritional risk and status, analyse the prevalence of undernutrition in a population of patients with diverse types of tumours. We aimed to identify difficulties regarding the use of the MUST tool (Malnutrition Universal Screening Tool) for nutritional risk by the students. This study included 35 cancer patients consecutively referenced for Radiotherapy (RT) in the Radiotherapy Department of the University Hospital of Santa Maria. Nutritional risk was evaluated by MUST; nutritional status by Patient Generated-Subjective Global Assessment (PG-SGA) validated and specific for oncology. Students identified 13 patients (36%) at moderate/high risk of undernutrition. According to PG-SGA, 31,5% (11/35) of patients presented moderate or severe undernutrition, of which 77% of patients needed individualized nutritional counselling. Students successfully detected undernourished patients using these specific methods. Risk of undernutrition and undernutrition are common in oncology, therefore indicating the critical need to educate all health professionals for risk screening and for the relevance of nutritional intervention in the multidisciplinary context. MUST is a simple and quick tool, that demonstrated to be adequate when applied by medical students, well accepted by these health professionals and effectively used. Nutritional risk evaluation can and must be performed by health professionals such as the medical team, as long as they are involved in patient's treatment. Our methodology may be used as a model allowing for early guidance to individualized intervention, human resources' optimization and education for the importance of nutrition care.

    The role of plain radiographs in monitoring the disease process in JIA is being increasingly superseded by MRI. The use of ultrasound by clinicians is contentious, but has the potential to corroborate and supplement the clinical impression of individual joint inflammation and it can be very useful for localising intra-articular treatment at the bedside. There are exciting developments in MRS technology which may eventually allow in vivo evaluation of the acute inflammatory process, measurement of early responses to treatment and detection of residual inflammation. The aim of this article is to describe a clinician's view of the current role of imaging in the diagnosis and monitoring of JIA. (orig.)

    New sequencing technologies provide in a short time and at low cost high amount of genomic sequences useful for applications such as: a) development of diagnostic PCRs and/or serological tests; b) detection of virulence factors (virulome) or genes/SNPs associated with resistance to antibiotics (resistome) and c) investigation of transmission and dissemination of bacterial pathogens. Thus, bacterial genomics of medical importance is useful to clinical microbiologists, to infectious diseases specialists as well as to epidemiologists. Determining the microbial composition of a sample by metagenomics is another application of new sequencing technologies, useful to understand the impact of bacteria on various non-infectious diseases such as obesity, asthma, or diabetes. Genomics and metagenomics will likely become a specialized diagnostic analysis.

    2013-06-01

    Beyond the well-known effects on blood pressure (BP) of the DASH and the Mediterranean diets, a large number of studies have investigated the possible a BP-lowering effect from different dietary supplements and nutraceuticals, mostly antioxidant agents with a high tolerability and safety profile. In particular, a relatively large body of evidence support the use of potassium, L-arginine, vitamin C, cocoa flavonoids, coenzyme Q10, controlled-release melatonin, and aged garlic extract. However there is a need for data about the long-term safety of a large part of these products. Moreover, further clinical research is advisable to identify between the available active nutraceuticals and those with the best cost-effectiveness and risk-benefit ratio for widespread use in a general population with low added cardiovascular risk related to uncomplicated hypertension.

    Ischemic stroke has been shown to cause hypermetabolism of glucose in the ischemic penumbra. Experimental and clinical data indicate that infarct-related systemic hyperglycemia is a potential therapeutic target in acute stroke. However, clinical studies aiming for glucose control in acute stroke have neither improved functional outcome nor reduced mortality. Thus, further studies on glucose metabolism in the ischemic brain are warranted. We used a rat model of stroke that preserves collateral flow. The animals were analyzed by [2-(18)F]-2-fluoro-2-deoxy-d-glucose positron emission tomography or magnetic resonance imaging during 90-minute occlusion of the middle cerebral artery and during 60 minutes after reperfusion. Results were correlated to magnetic resonance imaging of cerebral blood flow, diffusion of water, lactate formation, and histological data on cell death and blood-brain barrier breakdown. We detected an increased [2-(18)F]-2-fluoro-2-deoxy-d-glucose uptake within ischemic regions succumbing to infarction and in the peri-infarct region. Magnetic resonance imaging revealed impairment of blood flow to ischemic levels in the infarct and a reduction of cerebral blood flow in the peri-infarct region. Magnetic resonance spectroscopy revealed lactate in the ischemic region and absence of lactate in the peri-infarct region. Immunohistochemical analyses revealed apoptosis and blood-brain barrier breakdown within the infarct. The increased uptake of [2-(18)F]-2-fluoro-2-deoxy-d-glucose in cerebral ischemia most likely reflects hypermetabolism of glucose meeting increased energy needs of ischemic and hypoperfused brain tissue, and it occurs under both anaerobic and aerobic conditions measured by local lactate production. Infarct-related systemic hyperglycemia could serve to facilitate glucose supply to the ischemic brain. Glycemic control by insulin treatment could negatively influence this mechanism. © 2015 American Heart Association, Inc.

  13. Nocebo phenomena in medicine: their relevance in everyday clinical practice.

    Häuser, Winfried; Hansen, Ernil; Enck, Paul

    2012-06-01

    Nocebo phenomena are common in clinical practice and have recently become a popular topic of research and discussion among basic scientists, clinicians, and ethicists. We selectively searched the PubMed database for articles published up to December 2011 that contained the key words "nocebo" or "nocebo effect." By definition, a nocebo effect is the induction of a symptom perceived as negative by sham treatment and/or by the suggestion of negative expectations. A nocebo response is a negative symptom induced by the patient's own negative expectations and/or by negative suggestions from clinical staff in the absence of any treatment. The underlying mechanisms include learning by Pavlovian conditioning and reaction to expectations induced by verbal information or suggestion. Nocebo responses may come about through unintentional negative suggestion on the part of physicians and nurses. Information about possible complications and negative expectations on the patient's part increases the likelihood of adverse effects. Adverse events under treatment with medications sometimes come about by a nocebo effect. Physicians face an ethical dilemma, as they are required not just to inform patients of the potential complications of treatment, but also to minimize the likelihood of these complications, i.e., to avoid inducing them through the potential nocebo effect of thorough patient information. Possible ways out of the dilemma include emphasizing the fact that the proposed treatment is usually well tolerated, or else getting the patient's permission to inform less than fully about its possible side effects. Communication training in medical school, residency training, and continuing medical education would be desirable so that physicians can better exploit the power of words to patients' benefit, rather than their detriment.

  14. Complementary feeding: clinically relevant factors affecting timing and composition.

    Exclusive breastfeeding for the first 6 mo of life followed by optimal complementary feeding are critical public health measures for reducing and preventing morbidity and mortality in young children. Clinical factors, such as birth weight, prematurity, and illness, that affect the iron and zinc requirements of younger infants are discussed. Maternal diet and nutritional status do not have a strong effect on the mineral content of human milk, but physiologic changes in milk and the infants' status determine the dependence of the infant on complementary foods in addition to human milk to meet iron and zinc requirements after 6 mo. The nature of zinc absorption, which is suitably characterized by saturation response modeling, dictates that plant-based diets, which are low in zinc, are associated with low absolute daily absorbed zinc, which is inadequate to meet requirements. Foods with a higher zinc content, such as meats, are much more likely to be sufficient to meet dietary requirements. Current plant-based complementary feeding patterns for older fully breastfed infants in both developed and developing countries pose a risk of zinc deficiency. The strong rationale for the potential benefits of providing meat as an early complementary food, and the examples of successful intervention programs, provide potent incentives to pursue broader implementation programs, with concurrent rigorous evaluation of both efficacy and effectiveness.

    To determine the frequency and characteristics of babesiosis cases, and to assess the impact of the introduction of a tick-borne infection diagnostic panel on babesiosis diagnosis in the region surrounding La Crosse, Wisconsin, where babesiosis in non-travelers was previously rare. In the spring of 2013, we conducted a point-in-time survey of Ixodes scopuloris ticks for the presence of Babesia microti. We also conducted a retrospective study of all babesiosis cases diagnosed in our health system between January 1, 2004, and November 1, 2013. Finally, we compared the number of babesiosis cases diagnosed during the study period before and after the June 1, 2012, introduction of a tick-borne infection diagnostic panel in our organization. Babesia microti was present in 5% of ticks surveyed in our region. Twenty-two cases. of babesiosis were diagnosed in our organization during the study period-19 since 2010. The tick-borne infection diagnostic panel was used widely by clinicians, with an attendant increase in babesiosis diagnoses. Babesiosis should be considered endemic in southwestern Wisconsin, and testing should be considered for patients with compatible clinical and laboratory features.

    Drug interactions are commonly seen in the treatment of cancer patients. Psychotropics are often indicated for these patients since they may also suffer from pre-existing psychological disorders or experience insomnia and anxiety associated with cancer therapy. Thus, the risk of anticancer drug (ACD)-psychotropic drug-drug interactions (DDIs) is high. Drug interactions were compiled from the British National Formulary (53rd edn), Lexi-Comp's Drug Information Handbook (15th edn), Micromedex (v5.1), Hansten & Horn's Drug Interactions (2000) and Drug Interaction Facts (2008 edn). Product information of the individual drugs, as well as documented literature on ACD-psychotropic interactions from PubMed and other databases was also incorporated. This paper identifies clinically important ACD-psychotropic DDIs that are frequently observed. Pharmacokinetic DDIs were observed for tyrosine kinase inhibitors, corticosteroids and antimicrotubule agents due to their inhibitory or inductive effects on cytochrome P450 isoenzymes. Pharmacodynamic DDIs were identified for thalidomide with central nervous system depressants, procarbazine with antidepressants, myelosuppressive ACDs with clozapine and anthracyclines with QT-prolonging psychotropics. Clinicians should be vigilant when psychotropics are prescribed concurrently with ACDs. Close monitoring of plasma drug levels should be carried out to avoid toxicity in the patient, as well as to ensure adequate chemotherapeutic and psychotropic coverage.

    BACKGROUND: Skin prick testing is the standard for diagnosing IgE-mediated allergies. A positive skin prick reaction, however, does not always correlate with clinical symptoms. A large database from a Global Asthma and Allergy European Network (GA(2)LEN) study with data on clinical relevance...... was used to determine the clinical relevance of sensitizations against the 18 most frequent inhalant allergens in Europe. The study population consisted of patients referred to one of the 17 allergy centres in 14 European countries (n = 3034, median age = 33 years). The aim of the study was to assess...... the clinical relevance of positive skin prick test reactions against inhalant allergens considering the predominating type of symptoms in a pan-European population of patients presenting with suspected allergic disease. METHODS: Clinical relevance of skin prick tests was recorded with regard to patient history...

    Full Text Available Graves’ disease is the most common cause of thyrotoxicosis in women of childbearing age. Approximately 1% of pregnant women been treated before, or are being treated during pregnancy for Graves’ hyperthyroidism. In pregnancy, as in not pregnant state, thyroid-stimulating hormone (TSH receptor (TSHR antibodies (TRAbs are the pathogenetic hallmark of Graves’ disease. TRAbs are heterogeneous for molecular and functional properties and are subdivided into activating (TSAbs, blocking (TBAbs, or neutral (N-TRAbs depending on their effect on TSHR. The typical clinical features of Graves’ disease (goiter, hyperthyroidism, ophthalmopathy, dermopathy occur when TSAbs predominate. Graves’ disease shows some peculiarities in pregnancy. The TRAbs disturb the maternal as well as the fetal thyroid function given their ability to cross the placental barrier. The pregnancy-related immunosuppression reduces the levels of TRAbs in most cases although they persist in women with active disease as well as in women who received definitive therapy (radioiodine or surgery before pregnancy. Changes of functional properties from stimulating to blocking the TSHR could occur during gestation. Drug therapy is the treatment of choice for hyperthyroidism during gestation. Antithyroid drugs also cross the placenta and therefore decrease both the maternal and the fetal thyroid hormone production. The management of Graves’ disease in pregnancy should be aimed at maintaining euthyroidism in the mother as well as in the fetus. Maternal and fetal thyroid dysfunction (hyperthyroidism as well as hypothyroidism are in fact associated with several morbidities. Monitoring of the maternal thyroid function, TRAbs measurement, and fetal surveillance are the mainstay for the management of Graves’ disease in pregnancy. This review summarizes the biochemical, immunological, and therapeutic aspects of Graves’ disease in pregnancy focusing on the role of the TRAbs in maternal and

    Full Text Available Background: Tibial torsion is an important anatomical parameter in clinical practice and displays variability among individuals. These variations are extremely significant in view of alignment guides such as those related to rotational landmarks of tibia in total knee arthroplasty. Further, precise knowledge and information pertaining to angle of tibial torsion also helps in correction of traumatic malunion or congenital maltorsion of tibia. Methods: The present study was carried out to determine the angle of tibial torsion in 100 adult dry tibia bones in the Department of Anatomy, Government Medical College, Amritsar. The study group comprised 50 males and 50 females with equal number of right- and left-sided bones. The measurements were meticulously recorded and the data were subjected to statistical analysis. The results were analyzed and discussed in the light of existing literature. Results: On the right side, it was found to be 29.84° ± 4.86°° (range = 22.00° -38.00° in males and 28.92° ± 5.10°° (range = 15.00°-38.00° in females. On the left side, it was found to be 28.00° ± 4.94°° (range = 20.00°-40.00°° in males and 28.12° ± 4.28°° (range = 20.00°-37.00°° in females. Conclusion: The present study is an endeavor to provide baseline data with reference to the angle of tibial torsion in the Indian population. The results of the study assume special importance in view of the technical advancements in reconstructive surgical procedures in orthopedic practice.

    Numerous members of the genus Exophiala are potential agents of human and animal mycoses. The majority of these infections are cutaneous and superficial, but also fatal systemic infections are known. We re-identified 188 clinical isolates from the United States, which had a preliminary morphological identification of Exophiala species, by sequencing internal transcribed spacer (ITS) region of the rRNA. Molecular identifications of the strains were as follows, in order of frequency: 55 E. dermatitidis (29.3%), 37 E. xenobiotica (19.7%), 35 E. oligosperma (18.6%), 13 E. lecanii-corni (6.9%), 12 E. phaeomuriformis (6.4%), 7 E. jeanselmei (3.7%), 7 E. bergeri (3.7%), 6 E. mesophila (3.2%), 5 E. spinifera (2.7%), 3 Exophiala sp. 1 (1.6%), 3 E. attenuata (1.6%), 3 Phialophora europaea (1.3%), 1 E. heteromorpha (0.5%), and 1 Exophiala sp. 2 (0.5%) strains. Exophiala strains were repeatedly isolated from deep infections (39.9%) involving lung, pleural fluid, sputum, digestive organs (stomach, intestines, bile), heart, brain, spleen, bone marrow, blood, dialysis fluid, lymph node, joint, breast, middle ear, throat, and intraocular tissues. About 38.3% of the Exophiala spp. strains were agents of cutaneous infections including skin, mucous membranes, nail, and corneal epithelium lesions. The other strains caused superficial infections (0.5%, including hair) or subcutaneous infection (12.0%, including paranasal sinusitis, mycetoma, and subcutaneous cyst). The systemic infections were preponderantly caused by E. dermatitidis, E. oligosperma, E. phaeomuriformis, E. xenobiotica, and E. lecanii-corni. Strains of E. bergeri, E. spinifera, E. jeanselmei, E. mesophila, and E. attenuata mainly induced cutaneous and subcutaneous infections. Since relatively few unknown ITS motifs were encountered, we suppose that the list of opportunistic Exophiala species in temperate climates is nearing completion, but a number of species still have to be described.

    A retrospective radiographical study. To compare the prediction abilities of T1 pelvic angle (TPA) and other parameters for postoperative sagittal balance, and investigate the relationships between these parameters and health-related quality of life. Using sagittal vertical axis (SVA) to assess sagittal alignment fails to take account of the pelvic compensation. A new parameter, TPA, has been recommended to represent the global sagittal balance of adult scoliosis. A retrospective review was performed on patients with adult scoliosis undergoing correction surgery from May 2009 to March 2013. The Spearman ρ was used to determine the correlations between the radiographical parameters (preoperative, postoperative, and changes) and the overall Oswestry Disability Index (ODI), visual analogue scale (VAS), and Scoliosis Research Society-22 (SRS-22) questionnaire scores. Significant correlations were found between the changes of TPA and the changes of lumbar lordosis, pelvic tilt, sacral slope, pelvic incidence, SVA, spinosacral angle, ODI, VAS, SRS-22, and pedicle subtraction osteotomy (PSO) degrees (P 0.05). Significant correlations were found between the changes of spinosacral angle and the changes of thoracolumbar kyphosis, TPA, ODI, VAS, SRS-22, and PSO degrees (P 0.05). TPA could better reflect the postoperative changes of sagittal alignment and health-related quality of life for patients with adult scoliosis. Moreover, the changes of TPA are strongly correlated to the osteotomy degrees for PSO and, TPA could be used as a reference parameter in surgical planning. 4.

Methods The clinical data of 18 cases of female pelvic tuberculosis which were misdiagnosed as ovary carcinoma from January 2002 to December 2011 in our hospital were concluded and analyzed retrospectively. Results Pelvic tuberculosis is more often occurred in Women in child-bearing period. The course of pelvic tuberculosis usually moved slowly. Pelvic tuberculosis had less typical symptoms and was poor in sensitivity and specificity of test. Therefore, misdiagnosis of pelvic tuberculosis are common. Conclusion We should pay more attention to pelvic tuberculosis, collect such medical histories completely and attach importance to tests correla- ted to tuberculosis. We can apply puncture under ultrasound-guided , laparoscopy and other methods reasonably, and then the probability of misdiagnosis of pelvic tuberculosis would be decreased.

    Full Text Available Abstract Ideally, a clinical trial should be able to demonstrate not only a statistically significant improvement in the primary efficacy endpoint, but also that the magnitude of the effect is clinically relevant. One proposed approach to address this question is a responder analysis, in which a continuous primary efficacy measure is dichotomized into "responders" and "non-responders." In this paper we discuss various weaknesses with this approach, including a potentially large cost in statistical efficiency, as well as its failure to achieve its main goal. We propose an approach in which the assessments of statistical significance and clinical relevance are separated.

    The multidisciplinary management of patients with pelvic trauma has improved prognosis, but mortality is still very high. The appropriate treatment strategy remains controversial, especially regarding the control of bleeding in patients whose clinical situation is extreme by using angiography or pelvic packing. We propose using a tool of evidence-based medicine (CAT) the benefit of the completion of pelvic packing in relation to a specific clinical question from a specific situation. What is best for the management of bleeding, extraperitoneal pelvic packing or angiography, in patients with hemodynamically unstable pelvic fracture in extremis? From this study we can conclude that angiography may improve control of bleeding in patients with arterial bleeding and hemodynamically stable but the packing has priority in patients with pelvic fractures and hemodynamic instability.

    To prospectively explore the clinical application of diffusion tensor imaging (DTI) and fibre tractography in evaluating the pelvic floor. Ten patients with pelvic organ prolapse, ten with pelvic floor symptoms and ten asymptomatic women were included. A two-dimensional (2D) spin-echo (SE) echo-planar imaging (EPI) sequence of the pelvic floor was acquired. Offline fibre tractography and morphological analysis of pelvic magnetic resonance imaging (MRI) were performed. Inter-rater agreement for quality assessment of fibre tracking results was evaluated using weighted kappa ({kappa}). From agreed tracking results, eigen values ({lambda}1, {lambda}2, {lambda}3), mean diffusivity (MD) and fractional anisotropy (FA) were calculated. MD and FA values were compared using ANOVA. Inter-rater reliability of DTI parameters was interpreted using the intra-class correlation coefficient (ICC). Substantial inter-rater agreement was found ({kappa} = 0.71 [95% CI 0.63-0.78]). Four anatomical structures were reliably identified. Substantial inter-rater agreement was found for MD and FA (ICC 0.60-0.91). No significant differences between groups were observed for anal sphincter, perineal body and puboperineal muscle. A significant difference in FA was found for internal obturator muscle between the prolapse group and the asymptomatic group (0.27 {+-} 0.05 vs 0.22 {+-} 0.03; P = 0.015). DTI with fibre tractography permits identification of part of the clinically relevant pelvic structures. Overall, no significant differences in DTI parameters were found between groups. circle Diffusion tensor MRI offers new insights into female pelvic floor problems. (orig.)

    To evaluate technical success, complications, and effective dose in patients undergoing CT fluoroscopy-guided iliosacral screw placement for the fixation of unstable posterior pelvic ring injuries. Our retrospective analysis includes all consecutive patients with vertical sacral fractures and/or injury of the iliosacral joint treated with CT fluoroscopy-guided screw placement in our department from 11/2005 to 03/2013. Interventions were carried out under general anesthesia and CT fluoroscopy (10-20 mAs; 120 kV; 16- or 128-row scanner, Siemens Healthcare, Erlangen, Germany). Technical outcome, major and minor complications, and effective patient dose were analyzed. We treated 99 consecutive patients (mean age 53.1 ± 21.7 years, 50 male, 49 female) with posterior pelvic ring instability with CT fluoroscopy-guided screw placement. Intervention was technically successful in all patients (n = 99). No major and one minor local complication occurred (1 %, secondary screw dislocation). General complications included three cases of death (3 %) due to pulmonary embolism (n = 1), hemorrhagic shock (n = 1), or cardiac event (n = 1) during a follow-up period of 30 days. General complications were not related to the intervention. Mean effective patient radiation dose per intervention was 12.28 mSv ± 7.25 mSv. Mean procedural time was 72.1 ± 37.4 min. CT fluoroscopy-guided screw placement for the treatment of posterior pelvic ring instabilities can be performed with high technical success and a low complication rate. This method provides excellent intrainterventional visualization of iliac and sacral bones, as well as the sacral neuroforamina for precise screw placement by applying an acceptable effective patient dose.

    Objective: To observe the clinical efficacy of Penyanqing Capsule (盆炎清胶囊, PYQC) in treating pelvic inflammation of Qi-stagnation with blood stasis syndrome. Methods: The randomized, single blinded, parallel positive drug controlled method was adopted, with 82 patients assigned into two groups by envelop method. The 42 patients in the treated group received PYQC 3 times a day, 4 capsules each time taken orally; the 40 patients in the control group were given orally Fuyankang tablets (妇炎康片, FYKT) 3 times a day, 6 tablets each time. The therapeutic course for both groups was 2 months, and 2 courses of treatment were given successively to observe the comprehensive effect, changes of symptoms and signs before and after treatment. The effects of PYQC on hemorrheological character in part of the patients and on the pathogenetic chlamydia and mycoplasma were also observed. Results: The total effective rate in the treated group was 83.3 %, which was insignificantly different from that in the control group ( 77.5 %, P > 0.05 ).However, PYQC could significantly lower the hemorrheologic indexes in patients and showed definite influence on the pathogenetic chlamydia and mycoplasma. Conclusion: PYQC has good therapeutic effect in treating chronic pelvic inflammation of Qi-stagnation with blood stasis syndrome, and showed definite effect on chlamydia and mycoplasma.

    2016-11-22

    Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas can exhibit a wide spectrum of macroscopic and microscopic appearances. This not only causes occasional difficulties for the reporting pathologist in distinguishing these tumours from other lesions, but is also relevant clinically. As evidence accumulates, it becomes clear that multiple macroscopic and histological features of these neoplasms are relevant to the risk for malignant transformation and, consequently, of prime importance for clinical patient management. The need for detailed reporting is therefore increasing. This review discusses the panoply of gross and microscopic features of IPMN as well as the recommendations from recent consensus meetings regarding the pathology reporting on this tumour entity.

    Full Text Available The objective of this prospective study was to determine the plasma levels of nitric oxide (NO in women with chronic pelvic pain secondary to endometriosis (n=24 and abdominal myofascial pain syndrome (n=16. NO levels were measured in plasma collected before and 1 month after treatment. Pretreatment NO levels (μM were lower in healthy volunteers (47.0±12.7 than in women with myofascial pain (64.2±5.0, P=0.01 or endometriosis (99.5±12.9, P<0.0001. After treatment, plasma NO levels were reduced only in the endometriosis group (99.5±12.9 vs 61.6±5.9, P=0.002. A correlation between reduction of pain intensity and reduction of NO level was observed in the endometriosis group [correlation = 0.67 (95%CI = 0.35 to 0.85, P<0.0001]. Reduction of NO levels was associated with an increase of pain threshold in this group [correlation = -0.53 (-0.78 to -0.14, P<0.0001]. NO levels appeared elevated in women with chronic pelvic pain diagnosed as secondary to endometriosis, and were directly associated with reduction in pain intensity and increase in pain threshold after treatment. Further studies are needed to investigate the role of NO in the pathophysiology of pain in women with endometriosis and its eventual association with central sensitization.

    The use of pelvic trainers in undergraduate teaching was evaluated, using a questionnaire based on examination findings of a series of four pelvic trainers by 20 medical students and 34 gynaecologists. The main outcome measures were the ability to correctly identify pelvic findings in the trainers, and the numbers of false positive findings. There were two adnexal masses in two of the trainers. One was correctly identified by 33 (14 (70%) medical students and 19 (56%) doctors) in one trainer, whereas the other was missed by 52 of 54 examiners. Prolapse was missed by 41 of 54. The normal pelvis was correctly identified by 30 (16 (80%) medical students and 20 (59%) doctors. There were 15 false positive identifications of adnexal masses (6 by medical students and 9 by doctors) and 22 false positive identification of uterine enlargements (5 by medical students and 17 by doctors). The pelvic trainers were of value in demonstrating the process of pelvic and speculum examination. Some of the clinical conditions emulated were missed by most of the gynaecologists, suggesting that they were not suitable for training students in abnormal findings. Although the figures were not statistically significant, there was a trend for qualified doctors rather than medical students to make false positive findings.

    Susana Monge

    Full Text Available BACKGROUND: The aim was to analyse trends in clinically relevant resistance to first-line antiretroviral drugs in Spain, applying the Stanford algorithm, and to compare these results with reported Transmitted Drug Resistance (TDR defined by the 2009 update of the WHO SDRM list. METHODS: We analysed 2781 sequences from ARV naive patients of the CoRIS cohort (Spain between 2007-2011. Using the Stanford algorithm "Low-level resistance", "Intermediate resistance" and "High-level resistance" categories were considered as "Resistant". RESULTS: 70% of the TDR found using the WHO list were relevant for first-line treatment according to the Stanford algorithm. A total of 188 patients showed clinically relevant resistance to first-line ARVs [6.8% (95%Confidence Interval: 5.8-7.7], and 221 harbored TDR using the WHO list [7.9% (6.9-9.0]. Differences were due to a lower prevalence in clinically relevant resistance for NRTIs [2.3% (1.8-2.9 vs. 3.6% (2.9-4.3 by the WHO list] and PIs [0.8% (0.4-1.1 vs. 1.7% (1.2-2.2], while it was higher for NNRTIs [4.6% (3.8-5.3 vs. 3.7% (3.0-4.7]. While TDR remained stable throughout the study period, clinically relevant resistance to first line drugs showed a significant trend to a decline (p = 0.02. CONCLUSIONS: Prevalence of clinically relevant resistance to first line ARVs in Spain is decreasing, and lower than the one expected looking at TDR using the WHO list. Resistance to first-line PIs falls below 1%, so the recommendation of screening for TDR in the protease gene should be questioned in our setting. Cost-effectiveness studies need to be carried out to inform evidence-based recommendations.

    Screening pelvic radiographs to rule out pelvic fractures are routinely used for the initial evaluation of pediatric blunt trauma. Recently, the utility of routine pelvic radiographs in certain subsets of patients with blunt trauma has been questioned. There is a growing amount of evidence that shows the clinical exam is reliable enough to obviate the need for routine screening pelvic radiographs in children. To identify variables that help predict the presence or absence of pelvic fractures in pediatric blunt trauma. We conducted a retrospective study from January 2005 to January 2010 using the trauma registry at a level 1 pediatric trauma center. We analyzed all level 1 and level 2 trauma victims, evaluating history, exam and mechanism of injury for association with the presence or absence of a pelvic fracture. Of 553 level 1 and 2 trauma patients who presented during the study period, 504 were included in the study. Most of these children, 486/504 (96.4%), showed no evidence of a pelvic fracture while 18/504 (3.6%) had a pelvic fracture. No factors were found to be predictive of a pelvic fracture. However, we developed a pelvic fracture screening tool that accurately rules out the presence of a pelvic fracture P = 0.008, NPV 99, sensitivity 96, 8.98 (1.52-52.8). This screening tool combines eight high-risk clinical findings (pelvic tenderness, laceration, ecchymosis, abrasion, GCS <14, positive urinalysis, abdominal pain/tenderness, femur fracture) and five high-risk mechanisms of injury (unrestrained motor vehicle collision [MVC], MVC with ejection, MVC rollover, auto vs. pedestrian, auto vs. bicycle). Pelvic fractures in pediatric major blunt trauma can reliably be ruled out by using our pelvic trauma screening tool. Although no findings accurately identified the presence of a pelvic fracture, the screening tool accurately identified the absence of a fracture, suggesting that pelvic radiographs are not warranted in this subset of patients.

    Laparoscopic pelvic lymph node dissection (LPLND) is a low-morbidity procedure used to stage prostate cancer accurately prior to definitive local therapy. To better select patients for LPLND, we reviewed the clinical features of 120 patients with clinically localized prostate cancer who underwent LPLND to define significant risk factors for nodal metastases. The age ranged from 43 to 79 years (mean 68). Serum prostate specific antigen (PSA) concentration ranged from 1.3 to 329 ng/mL, Gleason score ranged from 2 to 9, and clinical stage ranged from T1b to T3c. Nodal metastases were discovered in 15 patients (13%). Among men with a Gleason score > or = 7, 21% had nodal metastases (P = 0.004). A serum PSA > 20 ng/mL and clinical stage T1b, T2b, or greater also were statistically significant predictors of lymph node metastases (20% and 19%, respectively). In multivariate analysis, Gleason score significantly predicted nodal metastases when controlling for all other clinical measures. Therefore, LPLND is indicated for any patient with a Gleason score > or = 7, PSA > 20 ng/mL, and advanced clinical T stage, independently or in combination.

    Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance. (orig.) [German] Inzidentelle kardiovaskulaere Befunde sind ein haeufiges Phaenomen bei CT-Untersuchungen.

Die Mehrzahl der inzidentellen kardiovaskulaeren Befunde sind klinisch nur von untergeordneter Bedeutung, allerdings werden immer wieder auch hochgradig relevante Zufallsbefunde wie beispielsweise Aortenaneurysmata oder - gerade bei onkologischen Patienten - Thrombosen und thrombembolische Ereignisse detektiert. Jede CT-Untersuchung sollte gezielt nach inzidentellen Befunden durchsucht werden, da diese je nach klinischer Relevanz von entscheidender Bedeutung fuer das weitere klinische Management des Patienten sein koennen.

    National Institutes of Health category III prostatitis, also known as chronic prostatitis/chronic pelvic pain syndrome, is a common condition with significant impact on quality of life. This clinically defined syndrome has a multifactorial etiology and seems to respond best to multimodal therapy. At least half of these patients have pelvic floor spasm. There are several approaches to therapy including biofeedback, acupuncture, and myofascial release physical therapy. However, the only multicenter study of pelvic floor physical therapy for pelvic floor spasm in men failed to show an advantage over conventional Western massage. We have proposed a clinical phenotyping system called UPOINT to classify patients with urologic chronic pelvic pain and subsequently direct appropriate therapy. Here, we review the current approach to category III prostatitis and describe how clinical phenotyping with UPOINT may improve therapy outcomes.

    The use of personal mobile devices in the medical field has grown quickly, and a large proportion of physicians use their mobile devices as an immediate resource for clinical decision-making, prescription information and other medical information. The iTunes App Store (Apple, Inc.) contains approximately 20,000 apps in its "Medical" category, providing a robust repository of resources for clinicians; however, this represents only 2% of the entire App Store. The App Store does not have strict criteria for identifying content specific to practicing physicians, making the identification of clinically relevant content difficult. The objective of this study is to quantify the characteristics of existing medical applications in the iTunes App Store that could be used by emergency physicians, residents, or medical students. We found applications related to emergency medicine (EM) by searching the iTunes App Store for 21 terms representing core content areas of EM, such as "emergency medicine," "critical care," "orthopedics," and "procedures." Two physicians independently reviewed descriptions of these applications in the App Store and categorized each as the following: Clinically Relevant, Book/Published Source, Non-English, Study Tools, or Not Relevant. A third physician reviewer resolved disagreements about categorization. Descriptive statistics were calculated. We found a total of 7,699 apps from the 21 search terms, of which 17.8% were clinical, 9.6% were based on a book or published source, 1.6% were non-English, 0.7% were clinically relevant patient education resources, and 4.8% were study tools. Most significantly, 64.9% were considered not relevant to medical professionals. Clinically relevant apps make up approximately 6.9% of the App Store's "Medical" Category and 0.1% of the overall App Store. Clinically relevant apps represent only a small percentage (6.9%) of the total App volume within the Medical section of the App Store. Without a structured search

    We determined the efficacy and safety of pelvic floor myofascial physical therapy compared to global therapeutic massage in women with newly symptomatic interstitial cystitis/painful bladder syndrome. A randomized controlled trial of 10 scheduled treatments of myofascial physical therapy vs global therapeutic massage was performed at 11 clinical centers in North America. We recruited women with interstitial cystitis/painful bladder syndrome with demonstrable pelvic floor tenderness on physical examination and a limitation of no more than 3 years' symptom duration. The primary outcome was the proportion of responders defined as moderately improved or markedly improved in overall symptoms compared to baseline on a 7-point global response assessment scale. Secondary outcomes included ratings for pain, urgency and frequency, the O'Leary-Sant IC Symptom and Problem Index, and reports of adverse events. We compared response rates between treatment arms using the exact conditional version of the Mantel-Haenszel test to control for clustering by clinical center. For secondary efficacy outcomes cross-sectional descriptive statistics and changes from baseline were calculated. A total of 81 women randomized to the 2 treatment groups had similar symptoms at baseline. The global response assessment response rate was 26% in the global therapeutic massage group and 59% in the myofascial physical therapy group (p=0.0012). Pain, urgency and frequency ratings, and O'Leary-Sant IC Symptom and Problem Index decreased in both groups during followup, and were not significantly different between the groups. Pain was the most common adverse event, occurring at similar rates in both groups. No serious adverse events were reported. A significantly higher proportion of women with interstitial cystitis/painful bladder syndrome responded to treatment with myofascial physical therapy than to global therapeutic massage. Myofascial physical therapy may be a beneficial therapy in women with this

    Objectives To determine the efficacy and safety of pelvic floor Myofascial Physical Therapy (MPT) in women with newly-symptomatic IC/PBS, as compared to Global Therapeutic Massage (GTM). Materials and Methods A randomized controlled trial of 10 scheduled treatments of MPT vs. GTM was performed at 11 clinical centers located in North America. We recruited women with IC/PBS with demonstrable pelvic floor tenderness on physical examination and a limitation of no more than 3 years symptom duration. The primary outcome was the proportion of responders defined as ‘moderately improved’ or ‘markedly improved’ in overall symptoms compared to baseline on a 7-point scale Global Response Assessment (GRA). Secondary outcomes included ratings for pain, urgency, frequency; the O'Leary-Sant IC Symptom and Problem Index (ICSI/ICPI) and reports of adverse events. We compared response rates between treatment arms using the exact conditional version of the Mantel-Haenszel test to control for clustering by clinical center. For secondary efficacy outcomes, cross-sectional descriptive statistics and changes from baseline were calculated. Results Eighty-one women randomized to the two treatment groups had similar symptoms at baseline. The GRA response rate was 26% in the GTM group and 59% in the MPT group (p=0.0012). Pain, urgency, and frequency ratings and in ICSI/ICPI decreased in both groups during follow-up and were not significantly different between the groups. Pain was the most common adverse event, occurring at similar rates in both groups. There were no serious adverse events reported. Conclusions A significantly higher proportion of women with IC/PBS reponded to treatment with MPT than with GTM. MPT may be a beneficial therapy in women with this syndrome. PMID:22503015

    Grapefruit juice interacts with a number of drugs. This commentary provides feedback on a previously proposed approach for predicting clinically relevant interactions with grapefruit juice based on the average inherent oral bioavailability (F) and magnitude of increase in bioavailability with other CYP3A inhibitors of the drug. Additional factors such as variability of the magnitude of the pharmacokinetic interaction among individuals, product monograph cautionary statements and vulnerability of the patient population should be considered. A flow diagram is provided that should improve prediction of the pharmacokinetic interaction and clinical relevance for affected drugs and that recommends different courses of action for patient management. Forecasting the clinical importance of a particular drug interaction with grapefruit can be improved through consideration of additional readily available drug regulatory information. © 2016 John Wiley & Sons Ltd.

    Cystic echinococcosis caused by Echinococcus granulosus is still an important health problem in endemic areas. Cystic echinococcosis may involve different organs or areas with the most common sites being the liver and the lungs. Pelvic involvement has previously been reported and was mainly accepted as secondary to cystic echinococcosis in other organs, isolated pelvic involvement is very rare. In this case report, we aimed to present the case with pelvic cystic mass that was finally diagnosed with isolated pelvic cystic echinococcosis in and after the operation, and we would like to draw attention to include "cystic echinococcosis" in the differential diagnosis of pelvic masses.

Emerging evidence shows that bacteria and fungi can have synergistic or antagonistic interactions, each with important implications for human colonization and disease. It is now appreciated that some of these interactions may be strategic and helps promote the survival of one or both microorganisms within the host. This review will shed light on clinically relevant interactions between fungi and Gram-negative bacteria. Mechanism of interaction, host immune responses, and preventive measures will also be reviewed. © 2016 John Wiley & Sons Ltd.

    To describe chronic rectal mucosal damage after pelvic radiotherapy (RT) for cervical cancer and correlate these findings with clinical symptoms and radiation dose. Thirty-two patients who underwent pelvic RT were diagnosed with radiation-induced proctitis based on endoscopy findings. The median follow-up period was 35 months after external beam radiotherapy (EBRT) and intracavitary radiotherapy (ICR). The Vienna Rectoscopy Score (VRS) was used to describe the endoscopic findings and compared to the European Organization for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) morbidity score and the dosimetric parameters of RT (the ratio of rectal dose calculated at the rectal point [RP] to the prescribed dose, biologically effective dose [BED] at the RP in the ICR and EBRT plans, {alpha}/{beta} = 3). Rectal symptoms were noted in 28 patients (rectal bleeding in 21 patients, bowel habit changes in 6, mucosal stools in 1), and 4 patients had no symptoms. Endoscopic findings included telangiectasia in 18 patients, congested mucosa in 20, ulceration in 5, and stricture in 1. The RP ratio, BEDICR, BEDICR+EBRT was significantly associated with the VRS (RP ratio, median 76.5%; BEDICR, median 37.1 Gy3; BEDICR+EBRT, median 102.5 Gy3; p < 0.001). The VRS was significantly associated with the EORTC/RTOG score (p = 0.038). The most prevalent endoscopic findings of RT-induced proctitis were telangiectasia and congested mucosa. The VRS was significantly associated with the EORTC/RTOG score and RP radiation dose.

    The prevalence of pelvic floor disorders (PFD) and their impact on quality of life of women vary among different populations. The purpose of this study was to assess the prevalence of symptoms of PFD, and their degree of bother in a convenience sample of Lebanese women, and to evaluate health-care seeking (HCS) behavior related to PFD. Women visiting clinics in a University Medical Center in Beirut, Lebanon, completed the self-filled validated Arabic version of the Global Pelvic Floor Bother Questionnaire (PFBQ). Data covering demographics, comorbidities, and HCS behavior related to PFD were collected. Total individual PFBQ scores, individual PFD symptom scores and HCS behavior were correlated to demographic data and comorbidities. The study participants included 900 women. PFBQ scores were significantly higher in women of older age, women with a lower level of education, women with higher vaginal parity, and women who engaged in heavy lifting/physical activity. BMI >25 kg/m(2) was the strongest independent risk factor for the presence of PFD symptoms. The overall prevalence of urinary incontinence was 42 %. Anal incontinence was the most bothersome PFD. Almost two thirds of the women reported HCS due to any aspect of PFD. Among symptomatic women who believed that their PFD warranted HCS, financial concern was the most common obstacle irrespective of age and educational level. In this convenience sample of Lebanese women, PFD symptoms were common and were significantly correlated with demographic characteristics and self-reported comorbidities. The key reason for not seeking health care related to PFD was financial concern.

    We wanted to evaluate the correlation of mild renal pelvic dilatation (RPD) that is observed to be less than 10 mm on ultrasound (US) with urinary tract infection (UTI) and vesicoureteral reflux (VUR) in neonates. We reviewed 137 kidneys of 107 neonates who had RPD less than 10 mm on US. All the kidneys were divided into two groups: Group I (RPD <= 5.0 mm) and Group II (RPD > 5.0 mm), and we statistically analyzed the RPD change according to UTI and VUR. Seven neonates had VUR (5.1%), and there was no statistical significance between Group I (6 neonates, 5.6%) and Group II (1 neonate, 3.3%). Thirty seven cases (27%) had UTI and there was no statistical significance between Group I (30 cases, 28.0%) and Group II (7 cases, 23.3%). The RPD did not change in 81.8% of the cases, it increased in 4.4% of the cases and it decreased in 13.9% of the cases on follow up US. The incidence of VUR and UTI were not different according to the change of RPD. There were no statistical differences between the changes of RPD and the incidences of UTI and VUR in neonates with mild RPD less than 10 mm. Most of RPD did not change on the follow up US

    Pelvic inflammatory disease (PID) generates diagnostic difficulty even for experienced doctors. Junior doctors and nurses also assess women with symptoms suggestive of PID. We aimed to determine if and how PID diagnoses vary between clinicians with different experience levels. Cross-sectional study conducted in U.K. sexual health clinic, nested within a Chlamydia trachomatis (CT), and Neisseria gonorrhoea diagnostic test accuracy study. Proportions and characteristics of women diagnosed clinically with PID by clinicians with varying experience were compared. Outcomes included demographics, presenting symptoms and signs and CT, and CT and/or gonococcal (GC) (CT/GC) positivity. In 3804 women assessed by 36 clinicians, rates of PID, CT and GC were 4.4%, 10.5%, and 2.5%, with no differences between experienced and inexperienced clinicians (p=0.84, p=0.13 and p=0.07, respectively). 63.7% of PID diagnosed by experienced clinicians met Centers for Disease Control and Prevention (CDC) key clinical criteria versus 41.2% by inexperienced; experienced versus inexperienced OR 2.51; 95% CI 1.16 to 5.40). Proportions of CT (CT/GC)-positive PID increased with experience (5.9% (11.8%) to 31.9% (34.1%)); experienced versus inexperienced (OR 3.90; 95% CI 1.12 to 13.5). Percentages of women with CT (CT/GC) who were diagnosed with PID also rose with experience (2.2% (3.9%) to 14.2% (13.7%)), but CT prevalence in PID cases diagnosed by inexperienced clinicians (8.8%) was no greater than in all women they assessed (9.0%), suggesting poorer discriminative skills. Clinical diagnostic acumen for PID improves with experience. Inexperienced clinicians should focus on the presence of lower abdominal pain with pelvic tenderness and consider additional supportive symptoms, to improve specificity of their diagnoses.

    Full Text Available Tumor cell dissemination is a common phenomenon observed in most cancers of epithelial origin. One-third of breast cancer patients present with disseminated tumor cells (DTCs in bone marrow at time of diagnosis; these patients, as well as patients with persistent DTCs, have significantly worse clinical outcome than DTC-negative patients. Since DTC phenotype may differ from the primary tumor with regard to ER and HER2 status, reevaluation of predictive markers on DTCs may optimize treatment choices. In the present review, we report on the clinical relevance of DTC detection in breast cancer.

    Evidence is currently limited for the effect of exercise on breast cancer clinical outcomes. However, several of the reported physical benefits of exercise, including peak oxygen consumption, functional capacity, muscle strength and lean mass, cardiovascular risk factors, and bone health, have established associations with disability, cardiovascular disease risk, morbidity, and mortality. This review will summarize the clinically relevant physical benefits of exercise interventions in breast cancer survivors and discuss recommendations for achieving these benefits. It will also describe potential differences in intervention delivery that may impact outcomes and, lastly, describe current physical activity guidelines for cancer survivors.

    Background. Diethylthiourea is widely used in the rubber industry, particularly in neoprene rubber, and may cause allergic contact dermatitis. However, as thiourea allergens are not part of the European baseline series, the diagnosis of allergic contact dermatitis caused by thiourea compounds......, and positive reactions were found in 15% (13/88). Thus, 15% (37/239) had positive patch test reactions to diethylthiourea, all with current clinical relevance and all strong. Conclusion.

    2011-07-01

    The prognostic impact of minimal residual disease (MRD) has been demonstrated for several hematologic malignancies. While in acute lymphoblastic leukemias MRD assessment by polymerase chain reaction (PCR)-based methods has been established as an important tool for clinical risk assessment and is part of clinical management, data demonstrating a prognostic value of MRD in mantle cell lymphoma (MCL) were sparse and results from randomized trials have been published only recently. In the present review technical aspects of different MRD detection methods are discussed, as well as the prognostic relevance of MRD in the context of clinical trials in patients with MCL. Furthermore, recommendations are given for workflow and useful implication of MRD in future clinical trials design.

  14. Using mixed methods to identify and answer clinically relevant research questions.

    Shneerson, Catherine L; Gale, Nicola K

    2015-06-01

    The need for mixed methods research in answering health care questions is becoming increasingly recognized because of the complexity of factors that affect health outcomes. In this article, we argue for the value of using a qualitatively driven mixed method approach for identifying and answering clinically relevant research questions. This argument is illustrated by findings from a study on the self-management practices of cancer survivors and the exploration of one particular clinically relevant finding about higher uptake of self-management in cancer survivors who had received chemotherapy treatment compared with those who have not. A cross-sectional study generated findings that formed the basis for the qualitative study, by informing the purposive sampling strategy and generating new qualitative research questions. Using a quantitative research component to supplement a qualitative study can enhance the generalizability and clinical relevance of the findings and produce detailed, contextualized, and rich answers to research questions that would be unachievable through quantitative or qualitative methods alone.

  15. High Prevalence and Clinical Relevance of Genes Affected by Chromosomal Breaks in Colorectal Cancer.

    Directory of Open Access Journals (Sweden)

    Evert van den Broek

    Full Text Available Cancer is caused by somatic DNA alterations such as gene point mutations, DNA copy number aberrations (CNA and structural variants (SVs. Genome-wide analyses of SVs in large sample series with well-documented clinical information are still scarce. Consequently, the impact of SVs on carcinogenesis and patient outcome remains poorly understood. This study aimed to perform a systematic analysis of genes that are affected by CNA-associated chromosomal breaks in colorectal cancer (CRC and to determine the clinical relevance of recurrent breakpoint genes.Primary CRC samples of patients with metastatic disease from CAIRO and CAIRO2 clinical trials were previously characterized by array-comparative genomic hybridization. These data were now used to determine the prevalence of CNA-associated chromosomal breaks within genes across 352 CRC samples. In addition, mutation status of the commonly affected APC, TP53, KRAS, PIK3CA, FBXW7, SMAD4, BRAF and NRAS genes was determined for 204 CRC samples by targeted massive parallel sequencing. Clinical relevance was assessed upon stratification of patients based on gene mutations and gene breakpoints that were observed in >3% of CRC cases.In total, 748 genes were identified that were recurrently affected by chromosomal breaks (FDR 3% of cases, indicating that prevalence of gene breakpoints is comparable to the prevalence of well-known gene point mutations. Patient stratification based on gene breakpoints and point mutations revealed one CRC subtype with very poor prognosis.We conclude that CNA-associated chromosomal breaks within genes represent a highly prevalent and clinically relevant subset of SVs in CRC.

    'Relevance' is a key concept in adult learning. Hence, this study sought to examine students' perceptions of relevance of the teaching and learning in relation to different instructional designs employed in a Comprehensive Patient Care (CPC) course that aims to develop integrated clinical reasoning skills. Third to fifth year students (2009-2011) were asked to anonymously rate the relevance of the instructional design (RELID) they participated in by means of visual analogue scales at the School of Dentistry, University of Pretoria. They were also asked to rate their perceptions of the alignment between teaching and learning and outcomes (ATLO), assessments' contribution to learning (ACL), course organisation (CO) and teacher competence (TC). RELID served as the outcome measure in stepwise linear regression analyses. ATLO, ACL, CO, TC and the instructional design (case-based learning (CBL = 1) and the combination of discipline-based and lecture-based teaching in CPC (DB-LBT = 0)) served as the co-variables for each of the years of study. The analyses showed positive correlations between RELID and ATLO and between RELID and ACL for all the years of study. RELID was associated with TC in year three and four and CO was associated with RELID in year four and five. CBL outperformed DB-LBT in terms of perceived relevance of the teaching and learning. The results suggest that students' perceptions of the relevance of the instructional design may be enhanced when outcomes, teaching, learning and assessment are constructively aligned during the development of clinical reasoning skills. © 2015 John Wiley & Sons A/S.

    Purpose We determined the effects of alpha-blockers and quinolone in patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) classified by National Institute of Health (NIH) consensus group. Materials and Methods Data from a total of 111 patients who were diagnosed with CP/CPPS between June 2010 and June 2012 were analyzed retrospectively. The patients were classified into group 1 (category IIIA, n=40) and group 2 (category IIIB, n=71). Treatment using alfuzosin and levofloxacin was given to both groups for 6 weeks. International Prostate Symptom Score (IPSS) and NIH Chronic Prostatitis Symptom Index were measured before and after therapy. Results Group 1 had a significant decrease in total IPSS score, CPSI pain score, CPSI quality of life (QoL) score, and total CPSI score (p=0.043, p=0.006, p=0.015, and p=0.006, respectively). Group 2 had a significant decrease in IPSS voiding symptom score, IPSS storage symptom score, total IPSS, CPSI pain score, CPSI voiding score, CPSI QoL score, and total CPSI score (p=0.002, p=0.004, p=0.001, p=0.001, p=0.006, p=0.001, and p=0.001, respectively). The CPSI score was reduced by 6 points or more in 50.0% of patients (n=18) in group 1 and in 51.6% of patients (n=32) in group 2. However, there was no statistically significant difference between the changes in IPSS and CPSI scores across the 2 groups. Conclusions Although combination treatment reduced the CPSI score in both groups, there was no significant difference between the groups after combination treatment. We suggest that factors other than inflammation also contribute to symptoms associated with CP/CPPS. PMID:24741418

  1. Limited clinical relevance of mitochondrial DNA mutation and gene expression analyses in ovarian cancer

    2008-10-01

    Full Text Available Abstract Background In recent years, numerous studies have investigated somatic mutations in mitochondrial DNA in various tumours. The observed high mutation rates might reflect mitochondrial deregulation; consequently, mutation analyses could be clinically relevant. The purpose of this study was to determine if mutations in the mitochondrial D-loop region and/or the level of mitochondrial gene expression could influence the clinical course of human ovarian carcinomas. Methods We sequenced a 1320-base-pair DNA fragment of the mitochondrial genome (position 16,000-750 in 54 cancer samples and in 44 corresponding germline control samples. In addition, six transcripts (MT-ATP6, MT-CO1, MT-CYB, MT-ND1, MT-ND6, and MT-RNR1 were quantified in 62 cancer tissues by real-time RT-PCR. Results Somatic mutations in the D-loop sequence were found in 57% of ovarian cancers. Univariate analysis showed no association between mitochondrial DNA mutation status or mitochondrial gene expression and any of the examined clinicopathologic parameters. A multivariate logistic regression model revealed that the expression of the mitochondrial gene RNR1 might be used as a predictor of tumour sensitivity to chemotherapy. Conclusion In contrast to many previously published papers, our study indicates rather limited clinical relevance of mitochondrial molecular analyses in ovarian carcinomas. These discrepancies in the clinical utility of mitochondrial molecular tests in ovarian cancer require additional large, well-designed validation studies.

    Increased usage of computed tomography and magnetic resonance imaging has led to a large increase in identified pancreatic cysts of up to 25% in population-based studies. The clinical and economic relevance of identifying so many cystic lesions has not been established. Compared to other organs such as liver or kidney, dysontogenetic pancreatic cysts are rare. Pancreatic cysts comprise a variety of benign, premalignant or malignant lesions; however, precise diagnosis before resection has an accuracy of only 80%. The focus of recent research was the malignant potential of intraductal papillary mucinous neoplasms (IPMN) with the aim of establishing clinical pathways addressing risk of malignancy, age and comorbidity, treatment-related morbidity and mortality as well as cost-effectiveness of treatment and surveillance. The focus of this review is to analyze the clinical and socio-economic relevance as well as the cost-benefit relation for IPMNs. For analysis, the following MESH terms were used to identify original articles, reviews, and guidelines in PubMed: ('intraductal papillary mucinous neoplasm' OR 'pancreatic cysts') and (incidence OR relevance OR socio-economic OR economic OR cost-effectiveness OR cost-benefit). The retrieved publications were reviewed with a focus on clinical and socio-economic relevance in relation to the increasing incidence of IPMN. Addressing the increasing prevalence of pancreatic cystic lesions, recent consensus guidelines suggested criteria for risk stratification according to 'worrisome features' and 'high-risk stigmata'. Recent prospective cohort studies evaluated whether these can be applied in clinical practice. Evaluation of three different clinical scenarios with regard to costs and quality-adjusted life years suggested a better effectiveness of surveillance after initial risk stratification by endoscopic ultrasound-guided fine-needle aspiration with cyst fluid analysis compared with immediate resection or follow-up without

    Pelvic lymph nodal regions receive an incidental dose from conformal treatment of the prostate. This study was conducted to investigate the doses received by the different pelvic nodal regions with varying techniques used for prostate radiotherapy. Twenty patients of high-risk node-negative prostate cancer treated with intensity-modulated radiotherapy to the prostate alone were studied. Replanning was done for intensity-modulated radiotherapy, 3-dimensional conformal treatment, and 2-dimensional conventional radiotherapy with additional delineation of the pelvic nodal regions, namely, common iliac (upper and lower), presacral, internal iliac, obturator, and external iliac. Dose-volume parameters such as Dmean, D100%, D66%, D33%, V40, and V50 to each of the nodal regions were estimated for all patients. The obturator nodes received the highest dose among all nodal regions. The mean dose received by obturator nodal region was 44, 29, and 22 Gy from 2-dimensional conventional radiotherapy, 3-dimensional conformal treatment, and intensity-modulated radiotherapy, respectively. The mean dose was significantly higher when compared between 2-dimensional conventional radiotherapy and 3-dimensional conformal treatment ( P < .001), 2-dimensional conventional radiotherapy and intensity-modulated radiotherapy ( P < .001), and 3-dimensional conformal treatment and intensity-modulated radiotherapy ( P < .001). The D33% of the obturator region was 64, 39, and 37 Gy from 2-dimensional conventional radiotherapy, 3-dimensional conformal treatment, and intensity-modulated radiotherapy, respectively. The dose received by all other pelvic nodal regions was low and not clinically relevant. The incidental dose received by obturator regions is significant especially with 2-dimensional conventional radiotherapy and 3-dimensional conformal treatment techniques as used in the trials studying elective pelvic nodal irradiation. However, with intensity-modulated radiotherapy, this dose is lower

    Pelvic inflammatory disease (PID) remains an important source of preventable reproductive morbidity, but no recent studies have singularly focused on US sexually transmitted disease (STD) clinics in relationship to established guidelines for diagnosis and treatment. Of the 83,076 female patients seen in 14 STD clinics participating in the STD Surveillance Network, 1080 (1.3%) were diagnosed as having PID from 2010 to 2011. A random sample of 219 (20%) women were selected, and medical records were reviewed for clinical history, examination findings, treatment, and diagnostic testing. Our primary outcomes were to evaluate how well PID diagnosis and treatment practices in STD clinic settings follow the Centers for Disease Control and Prevention (CDC) treatment guidelines and to describe age group-specific rates of laboratory-confirmed Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) in patients clinically diagnosed as having PID in the last 12 months, inclusive of the PID visit. Among the 219 women, 70.3% of the cases met the CDC treatment case definition for PID, 90.4% had testing for CT and GC on the PID visit, and 68.0% were treated with a CDC-recommended outpatient regimen. In the last 12 months, 95.4% were tested for CT or GC, and positivity for either organism was 43.9% in women aged 25 years or younger with PID, compared with 19.4% of women older than 25 years with PID. Compliance with CDC guidelines was documented for many of the women with PID, though not all. Our findings underscore the need for continued efforts to optimize quality of care and adherence to current guidance for PID management given the anticipated expertise of providers in these settings.

    To assess the epidemiological features and the trend of care of patients diagnosed with pelvic inflammatory disease (PID) and to assess most predictive parameters of severe disease, for which surgical management is warranted, in particular when surgery is certain to cause permanent infertility. The study population was divided into 3 groups: medical therapy only, conservative surgery, and destructive surgery (surgical procedures that impaired fertility). Data from the 3 groups were compared with respect to general and medical history data, clinical signs on admission, laboratory tests, and ultrasound findings. The p value was considered significant when disease severity. Ultrasound evidence of ovaritis generally led to medical therapy. Conversely, when sonography revealed pyosalpinx or tuboovarian abscesses, surgery was performed. Clinical presentation is fundamental in diagnostic counseling but should be supplemented with further laboratory tests to detect inflammation and sonograms. The latter, along with CRP and D-dimer assays, may represent useful parameters to consider when planning patient management because they appear indicative of the need for surgical treatment.

    To investigate the antigen spreading pattern in the CHP-MAGE-A4-vaccinated patients and analyze the clinical relevance of antigen spreading pattern as a surrogate marker of patient survival. 12 patients who had been injected with 300 μg of CHP-MAGE-A4 and 0.5 Klinische Einheit of OK-432 in more than five vaccinations were analyzed. Increases in the anti-MAGE-A4-specific antibody response were observed in eight patients (66.7%), compared with six patients (50%) for anti-NY-ESO-1 and five patients (41.7%) for anti-MAGE-A3 after five vaccinations. We identified frequent antigen spreading following MAGE-A4 vaccinations without associations with the clinical response or patient prognosis. Antigen spreading pattern might reflect tumor shrinkage as a response to treatment and treatment history (clinical trial registration number: UMIN000001999).

    Many patients with osteosarcoma (OS) will succumb to distant metastasis, often involving the lungs. Effective therapies for treating lung metastases depend on the availability of a clinically relevant pre-clinical model. Mice were surgically implanted with OS tumor fragments. The time course of primary tumor growth and subsequent spread to the lung were determined. Following development of a lytic and proliferative primary bone lesion, tumor metastasized to the lung in the majority of mice. There was no evidence of tumor at three weeks, but 10 out of 11 mice ultimately developed secondary OS in the lung within 12 weeks. Implantation of OS tumor fragments leads to the development of primary bone tumors and secondary lung metastases, recapitulating the clinical behavior of OS. This model offers an advantage over cell suspension injection models by precluding initial seeding of the lung with tumor cells.

    Diabetic retinopathy (DR) is a vision-threatening complication from diabetes mellitus, a medical condition that is rising globally. Unfortunately, many patients are unaware of this complication because of absence of symptoms. Regular screening of DR is necessary to detect the condition for timely treatment. Content-based image retrieval, using archived and diagnosed fundus (retinal) camera DR images can improve screening efficiency of DR. This content-based image retrieval study focuses on two DR clinical findings, microaneurysm and neovascularization, which are clinical signs of non-proliferative and proliferative diabetic retinopathy. The authors propose a multi-class multiple-instance image retrieval framework which deploys a modified color correlogram and statistics of steerable Gaussian Filter responses, for retrieving clinically relevant images from a database of DR fundus image database.

    The use of lupine in food has been increasing during the last decade and allergic reactions to lupine have been reported, especially in peanut-allergic patients. The frequency and the degree of cross-reactivity to other legumes are not known. The aim of the study was to investigate the frequency of sensitization to lupine, and in addition to pea and soy, and its clinical relevance, in peanut-sensitized patients. Furthermore, to determine the eliciting dose (ED) for lupine using double-blind placebo-controlled food challenges (DBPCFC). Thirty-nine unselected peanut-sensitized patients were evaluated by skin prick tests (SPT) and ImmunoCAP to lupine, pea, and soy. Clinical reactivity was measured by DBPCFC for lupine, and by history for pea and soy. Eighty-two percent of the study population was sensitized to lupine, 55% to pea, and 87% to soy. Clinically relevant sensitization to lupine, pea, or soy occurred in 35%, 29%, and 33% respectively of the study population. None of the patients was aware of the use of lupine in food. The lowest ED for lupine, inducing mild subjective symptoms, was 0.5 mg, and the no observed adverse effect level (NOAEL) was 0.1 mg. No predictive factors for lupine allergy were found. In peanut-sensitized patients, clinically relevant sensitization to either lupine or to pea or soy occurs frequently. The ED for lupine is low (0.5 mg), which is only fivefold higher than for peanut. Patients are not aware of lupine allergy and the presence of lupine in food, indicating that education is important to build awareness.

    Flavio Meirelles Siqueira

    Full Text Available OBJECTIVES: To evaluate the clinical response and success rate after periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome and to report the safety of endovascular treatment and its rate of complications. METHODS: Retrospective cohort of patients undergoing endovascular treatment of pelvic congestion syndrome in our department from January 2012 to November 2015. Data were analyzed based on patient background, imaging findings, embolized veins, rate of complications, and clinical response as indicated by the visual analog pain scale. RESULTS: We performed periuterine varices embolization in 22 patients during the study, four of which required a second embolization. Seventeen patients reported a reduction in pelvic pain after the first embolization and three patients reported a reduction in pelvic pain after the second embolization. Minor complications were observed in our patients, such as postural hypotension, postoperative pain, and venous perforation during the procedure, without clinical repercussion. CONCLUSION: Periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome appears to be an effective and safe technique.

    The application of machine learning to epilepsy can be used both to develop clinically useful computer-aided diagnostic tools, and to reveal pathologically relevant insights into the disease. Such studies most frequently use neurologically normal patients as the control group to maximize the pathologic insight yielded from the model. This practice yields potentially inflated accuracy because the groups are quite dissimilar. A few manuscripts, however, opt to mimic the clinical comparison of epilepsy to non-epileptic seizures, an approach we believe to be more clinically realistic. In this manuscript, we describe the relative merits of each control group. We demonstrate that in our clinical quality FDG-PET database the performance achieved was similar using each control group. Based on these results, we find that the choice of control group likely does not hinder the reported performance. We argue that clinically applicable computer-aided diagnostic tools for epilepsy must directly address the clinical challenge of distinguishing patients with epilepsy from those with non-epileptic seizures.

    Array comparative genomic hybridization (aCGH) is a powerful tool for the molecular elucidation and diagnosis of disorders resulting from genomic copy-number variation (CNV). However, intragenic deletions or duplications--those including genomic intervals of a size smaller than a gene--have remained beyond the detection limit of most clinical aCGH analyses. Increasing array probe number improves genomic resolution, although higher cost may limit implementation, and enhanced detection of benign CNV can confound clinical interpretation. We designed an array with exonic coverage of selected disease and candidate genes and used it clinically to identify losses or gains throughout the genome involving at least one exon and as small as several hundred base pairs in size. In some patients, the detected copy-number change occurs within a gene known to be causative of the observed clinical phenotype, demonstrating the ability of this array to detect clinically relevant CNVs with subkilobase resolution. In summary, we demonstrate the utility of a custom-designed, exon-targeted oligonucleotide array to detect intragenic copy-number changes in patients with various clinical phenotypes.

    Evidence-based practice (EBP) continues to gain momentum within health care. The purpose of this four-part EBP series is to provide an introductory overview of the EBP process, emphasizing EBP steps one through three, in order to assist nurse practitioners (NPs) in building EBP skills that can be integrated into clinical practice. The relevance of EBP to the NP's clinical practice, an introduction to the EBP process steps, and clinical inquiry process begin the series. Scientific literature review, gray literature, and online evidence-based practice databases and resources. EBP has become increasingly important to NPs, yet there is evidence suggesting it is not being fully implemented in clinical practice. EBP is one way to keep the busy NP's knowledge up to date, enhance clinical judgment, and augment the existing provider-client decision-making process. The principles of EBP have become the cornerstone strategy for NPs to translate research findings into clinical practice. Practicing in an ever-changing healthcare environment, NPs have a responsibility to provide their clients with the best available evidence, while incorporating that evidence into the provider-client decision-making process. ©2012 The Author(s) Journal compilation ©2012 American Academy of Nurse Practitioners.

    Objectif : La douleur pelvienne chronique (DPC) est un trouble prévalent, débilitant et coûteux. Bien que des lignes directrices nationales et des données empiriques soutiennent l’utilisation d’un modèle de soins multidisciplinaires pour les patientes qui présentent des DPC, les cliniques canadiennes offrant un tel modèle sont peu nombreuses. Le BC Women’s Centre for Pelvic Pain and Endometriosis a été créé pour répondre à ce besoin et un intérêt a été manifesté à l’endroit des effets de ce modèle de soins sur le fardeau de la maladie en Colombie-Britannique. Nous avons cherché à créer une approche envers son évaluation en utilisant le cadre de référence RE-AIM (Reach, Efficacy, Adoption, Implementation, Maintenance) pour déterminer les effets de ce modèle de soins et pour orienter le processus décisionnel clinique et la formulation de politiques en la matière. Méthodes : Le cadre d’évaluation RE-AIM a été appliqué pour nous permettre d’envisager les diverses dimensions des effets du BC Centre. Les mesures proposées, les sources de données et les stratégies de gestion des données pour cette approche à méthodes mixtes ont été identifiées. Résultats : Les cinq dimensions des effets ont été prises en considération aux niveaux personnel et organisationnel, et des indicateurs correspondants ont été proposés pour en permettre l’intégration dans l’infrastructure de données existante, en vue de faciliter la collecte des données et l’évaluation précoce du programme. Conclusion : Le cadre RE-AIM peut être appliqué à l’évaluation d’une clinique multidisciplinaire visant la douleur pelvienne chronique. Cela permettra la tenue d’une meilleure évaluation des effets de modèles novateurs de soins chez les femmes qui connaissent des douleurs pelviennes chroniques.

    Pelvic inflammatory disease (PID) occurs when pathogens, often sexually transmitted, ascend to the upper genital tract, yet a causative pathogen is not detected in a substantial proportion of diagnosed PID. We assessed the characteristics associated with PID in women in whom chlamydia, gonorrhoea, Mycoplasma genitalium (MG) and bacterial vaginosis (BV) were not detected ('pathogen-negative-PID'). Cross-sectional analysis of routinely collected clinical data from new female patients attending a sexual health clinic between 2006 and 2013. Women were eligible if they had been diagnosed with PID and tested for genital chlamydia, gonorrhoea, MG and BV. Logistic regression was conducted to identify characteristics associated with pathogen-negative-PID. Among 330 women with clinically diagnosed PID, 204 (61.8%, 95% CI 56.3% to 67.1%) had pathogen-negative-PID. Compared with pathogen-positive-PID, pathogen-negative-PID cases were more likely to be aged ≥30 years (adjusted odds ratio (AOR) 1.7, 95% CI 1.0 to 3.0), had less evidence of vaginal inflammation (AOR 0.5, 95% CI 0.3 to 0.9) and reported less unprotected sex (AOR 0.6, 95% CI 0.4 to 1.0). These findings highlight uncertainties around PID diagnosis and aetiology. Pathogen-negative-PID could represent (i) a false positive diagnosis where the woman does not have a sexually transmitted infection (STI) or PID, (ii) PID of another microbiological aetiology or associated with a past STI or (iii) PID where the cervical infection has cleared. However, until diagnostic biomarkers are available, PID treatment should be based on clinical features and sexual risk. Published by the BMJ Publishing Group Limited.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is still a challenge to manage for all physicians. We feel that a summary of the current literature and a systematic review to evaluate the therapeutic efficacy of flower pollen extract would be helpful for physicians who are considering a phytotherapeutic approach to treating patients with CP/CPPS. A comprehensive search of the PubMed and Embase databases up to June 2016 was performed. This comprehensive analysis included both pre-clinical and clinical trials on the role of flower pollen extract in CP/CPPS patients. Moreover, a meta-analysis of available randomized controlled trials (RCTs) was performed. The NIH Chronic Prostatitis Symptom Index (NIH-CPSI) and Quality of Life related questionnaires (QoL) were the most commonly used tools to evaluate the therapeutic efficacy of pollen extract. Pre-clinical studies demonstrated the anti-inflammatory and anti-proliferative role of pollen extract. 6 clinical, non-controlled studies including 206 patients, and 4 RCTs including 384 patients were conducted. The mean response rate in non-controlled studies was 83.6% (62.2%-96.0%). The meta-analysis revealed that flower pollen extract could significantly improve patients' quality of life [OR 0.52 (0.34-.0.81); p = 0.02]. No significant adverse events were reported. Most of these studies presented encouraging results in terms of variations in NIH-CPSI and QoL scores. These studies suggest that the use of flower pollen extract for the management of CP/CPPS patients is beneficial. Future publications of robust evidence from additional RCTs and longer-term follow-up would provide more support encouraging the use of flower pollen extracts for CP/CPPS patients.

  17. MDMA, methamphetamine, and CYP2D6 pharmacogenetics: what is clinically relevant?

    Full Text Available In vitro human studies show that the metabolism of most amphetamine-like psychostimulants is regulated by the polymorphic cytochrome P450 isozyme CYP2D6. Two compounds, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA, were selected as archetypes to discuss the translation and clinical significance of in vitro to in vivo findings. Both compounds were chosen based on their differential interaction with CYP2D6 and their high abuse prevalence in society. Methamphetamine behaves as both a weak substrate and competitive inhibitor of CYP2D6, while MDMA acts as a high affinity substrate and potent mechanism-based inhibitor (MBI of the enzyme. The MBI behavior of MDMA on CYP2D6 implies that subjects, irrespective of their genotype/phenotype, are phenocopied to the poor metabolizer phenotype. The fraction of metabolic clearance regulated by CYP2D6 for both drugs is substantially lower than expected from in vitro studies. Other isoenzymes of cytochrome P450 and a relevant contribution of renal excretion play a part in their clearance. These facts tune down the potential contribution of CYP2D6 polymorphism in the clinical outcomes of both substances. Globally, the clinical relevance of CYP2D6 polymorphism is lower than that predicted by in vitro studies.

    An interesting case of pelvic actinomycosis with paculiar clinical manifestation is presented. A 42 years-old patient came to our emergency service for an abdominal pelvic pain and fever. Past history showed IUD in situ for over 15 years. The patient was submitted to a ultrasonographic scan and a complete hematological screening was performed. The diagnosis was of subacute abdomen, and an exploratory laparotomy was carried out. During laparotomy an atypical reactive tissue and a suppurative cavity were found. The histological finding of tissue biopsy showed pelvic actinomycosis. On the basis of these findings the conclusion is drawn that a better prevention of pelvic actinomycosis is necessary of its diffusion in the last years due to sexual habit changes.

    Two patients presented with ureteric obstruction, and voiding symptoms and constipation, respectively, and were examined by means of intravenous urography and computed tomography. One patient was additionally examined by means of MR tomography. After CT (performed in both patients) and MRT (performed in one patient) had shown a diffuse, contrast-enhancing, infiltrating process in the small pelvis with infiltration of adjacent organs and vessels, surgical biopsy proved the diagnosis of idopathic pelvic fibrosis. Extension of retroperitoneal fibrosis below the pelvic rim is very rare. Clinical symptoms of pelvic fibrosis are variable and imaging findings may lead to a broad list of differential diagnoses. We present two patients with idiopathic pelvic fibrosis and discuss radiological findings and differential diagnoses of this rare disease. (orig.)

    The objective of this paper was to review and evaluate the literature on metronidazole-associated peripheral neuropathy and determine the relevance in clinical practice. MEDLINE/PubMed, EBSCO, and Google Scholar were searched through February 2017 using the search terms metronidazole and peripheral neuropathy, or polyneuropathy, or paresthesia, or neurotoxicity. Relevant case reports, retrospective studies, surveys, and review articles were included. Bibliographies of all relevant articles were reviewed for additional sources. Overall, metronidazole is generally well tolerated but serious neurotoxicity, including peripheral neuropathy, has been reported. The overall incidence of peripheral neuropathy associated with metronidazole is unknown. Our review found 36 case reports (40 unique patients) of metronidazole-associated peripheral neuropathy with the majority of cases receiving >42 total grams (>4 weeks) of therapy (31 out of 40). In addition, we reviewed 13 clinical studies and found varying rates of peripheral neuropathy from 0-50%. Within these clinical studies, we found a higher incidence of peripheral neuropathy in patients receiving >42 total grams (>4 weeks) of metronidazole compared to those patients receiving ≤ 42 total grams (17.9% vs 1.7%). Nearly all patients had complete resolution of symptoms. In conclusion, peripheral neuropathy is exceedingly rare in patients who receive ≤ 42 total grams of metronidazole. Patients who receive larger total doses may be at higher risk of peripheral neuropathy but most patients have resolution of symptoms after discontinuing therapy. Antimicrobial stewardship programs may consider use of antibiotic combinations that include metronidazole over broad-spectrum alternatives when treating with ≤42 grams of the drug (≤4 weeks).

    Medical anthropology provides an excellent resource for nursing research that is relevant to clinical nursing. By expanding the understanding of ethnographic research beyond ethnicity, nurses can conduct research that explores patient's constructions and explanatory models of health and healing and how they make meaning out of chronic conditions and negotiate daily life. These findings can have applicability to culturally competent care at both the organizational or systems level, as well as in the patient/provider encounter. Individual patient care can be improved by applying ethnographic research findings to build provider expertise and then using a cultural negotiation process for individualized patient care.

    Chronic metabolic acidosis (CMA) is a common complication of the more advanced stages of chronic kidney diseases (CKD), and is associated with morbidity and mortality of CKD patients and possibly with the progression of renal disease. Nevertheless, there is limited evidence or information on the prevalence, the potential causal factors, the clinical impact and the effects of correction of CMA in kidney transplant recipients. In this review, we briefly look at the more relevant, though scanty, studies which have, over time, addressed the above-mentioned points, with the hope that in the future the interest of transplant nephrologists and surgeons will grow towards this unreasonably neglected issue.

    2012-01-01

    Full Text Available Nonmotor symptoms (NMSs of Parkinson’s disease (PD are common, but they are often underrecognized in clinical practice, because of the lack of spontaneous complaints by the patients, and partly because of the absence of systematic questioning by the consulting physician. However, valid specific instruments for identification and assessment of these symptoms are available in 2012. The administration of the self-completed screening tool, NMSQuest, associated with questioning during the consultation, improves the diagnosis of NMSs. NMSs play a large role in degradation of quality of life. More relevant NMSs are described in this review, mood disorders, impulse control disorders, cognitive deficits, hallucinations, pain, sleep disorders, and dysautonomia.

    Carbon dioxide production during cardiopulmonary bypass derives from both the aerobic metabolism and the buffering of lactic acid produced by tissues under anaerobic conditions. Therefore, carbon dioxide removal monitoring is an important measure of the adequacy of perfusion and oxygen delivery. However, routine monitoring of carbon dioxide removal is not widely applied. The present article reviews the main physiological and pathophysiological sources of carbon dioxide, the available techniques to assess carbon dioxide production and removal and the clinically relevant applications of carbon dioxide-related variables as markers of the adequacy of perfusion during cardiopulmonary bypass.

    2011-06-01

    This article reviews the culture of biomedicine and current practices in pain management education, which often merge to create a hostile environment for effective chronic pain care. Areas of cultural tensions in chronic pain frequently involve the struggle to achieve credibility regarding one's complaints of pain (or being believed that the pain is real) and complying with pain medication protocols. The clinically relevant continuum model is presented as a framework allowing providers to approach care from an evidence-based, culturally appropriate (patient centered) perspective that takes into account the highest level of evidence available, provider expertise, and patient preferences and values.

    Full Text Available Abstract Cardiovascular disease is the major cause of morbidity and mortality associated with diabetes. There is increasing evidence that advanced glycation endproducts (AGEs play a pivotal role in atherosclerosis, in particular in diabetes. AGE accumulation is a measure of cumulative metabolic and oxidative stress, and may so represent the "metabolic memory". Furthermore, increased AGE accumulation is closely related to the development of cardiovascular complications in diabetes. This review article will focus on the clinical relevance of measuring AGE accumulation in diabetic patients by focusing on AGE formation, AGEs as predictors of long-term complications, and interventions against AGEs.

    2008-07-01

    Full Text Available Abstract Background St. John's wort (SJW, used to treat depression, is popular in the USA, Canada, and parts of Europe. However, there are documented interactions between SJW and prescription medications including warfarin, cyclosporine, indinavir, and oral contraceptives. One source of information about these safety considerations is the product label. The aim of this study was to evaluate the clinically relevant safety information included on labeling in a nationally representative sample of SJW products from the USA. Methods Eight clinically relevant safety issues were identified: drug interactions (SJW-HIV medications, SJW-immunosupressants, SJW-oral contraceptives, and SJW-warfarin, contraindications (bipolar disorder, therapeutic duplication (antidepressants, and general considerations (phototoxicity and advice to consult a healthcare professional (HCP. A list of SJW products was identified to assess their labels. Percentages and totals were used to present findings. Results Of the seventy-four products evaluated, no product label provided information for all 8 evaluation criteria. Three products (4.1% provided information on 7 of the 8 criteria. Four products provided no safety information whatsoever. Percentage of products with label information was: SJW-HIV (8.1%, SJW-immunosupressants (5.4%, SJW-OCPs (8.1%, SJW-warfarin (5.4%, bipolar (1.4%, antidepressants (23.0%, phototoxicity (51.4%, and consult HCP (87.8%. Other safety-related information on labels included warnings about pregnancy (74.3%, lactation (64.9%, discontinue if adverse reaction (23.0%, and not for use in patients under 18 years old (13.5%. The average number of a priori safety issues included on a product label was 1.91 (range 0–8 for 23.9% completeness. Conclusion The vast majority of SJW products fail to adequately address clinically relevant safety issues on their labeling. A few products do provide an acceptable amount of information on clinically relevant safety

    Full Text Available The in vitro antifungal activity of nine dirutheniumpentadithiocarbamate complexes C1–C9 was investigated and assessed for its activity against four different fungal species with clinical interest and related to invasive fungal infections (IFIs, such as Candida spp. [C. albicans (two clinical isolates, C. glabrata, C. krusei, C. parapsolisis, C. tropicalis, C.dubliniensis (six clinical isolates], Paracoccidioides brasiliensis (seven clinical isolates, Cryptococcus neoformans and Sporothrix schenckii. All synthesized complexes C1–C9 and also the free ligands L1–L9 were submitted to in vitro tests against those fungi and the results are very promising, since some of the obtained MIC (minimal inhibitory concentration values were very low (from 10−6 mol mL−1 to 10−8 mol mL−1 against all investigated clinically relevant fungal pathogens, except for C. glabrata, that the MIC values are close to the ones obtained for fluconazole, the standard antifungal agent tested. Preliminary structure-activity relations (SAR might be suggested and a strong influence from steric and lipophilic parameters in the antifungal activity can be noticed. Cytotoxicity assays (IC50 showed that the complexes are not as toxic (IC50 values are much higher—30 to 200 fold—than MIC values. These ruthenium complexes are very promising lead compounds for novel antifungal drug development, especially in IFIs, one of most harmful emerging infection diseases (EIDs.

    PURPOSE To develop an atlas of the clinical target volumes (CTV) definitions for the post-operative radiotherapy of endometrial and cervical cancer to be utilized for planning pelvic Intensity Modulated Radiation Therapy (IMRT). METHODS AND MATERIALS The Radiation Therapy Oncology Group (RTOG) led an international collaberation of cooperative groups in development of the atlas. The groups included RTOG the Gynecologic Oncology Group (GOG), the National Cancer Institute of Canada (NCIC), the European Society of Therapeutic Radiology and Oncology (ESTRO), and the American College of Radiology Imaging Network (ACRIN). Members of the group were asked by questionnaire to define areas that were to be included in the CTV and were asked to outline theses areas on individual Computed Tomography (CT) images. The initial formulation of the group began in late 2004 and culminated with a formal consensus conference in June of 2005. RESULTS The committee achieved a consensus CTV definition for the post-operative therapy of endometrial and cervical cancer. The CTV should include the common, external, and internal iliac lymph node regions. The upper 3.0 cm of vagina and paravaginal soft tissue lateral to the vagina should also be included. For patients with cervical cancer, or endometrial cancer with cervical stromal invasion, it is also recommended that the CTV include the presacral lymph node-region. CONCLUSIONS This manuscript serves as an international template for the definition of the CTV for the post-operative IMRT of endometrial and cervical cancer. PMID:18037584

    The "curative potential" in almost any clinical setting depends on a caregiver establishing and maintaining an empathic connection with patients so as to achieve "narrative competence" in discerning and acting in accord with their preferences and best interests. The "narrative medicine" model of shared "close reading of literature and reflective writing" among clinicians as a means of fostering a capacity for clinical empathy has gained validation with recent empirical studies demonstrating the enhancement of theory of mind (ToM), broadly conceived as empathy, in readers of literary fiction. Talmudic legends, like that of Rabbi Judah's death, are under-appreciated, relevant sources of literary fiction for these efforts. The limitations of narrative medicine are readily counterbalanced by simultaneously practiced attention to traditional bioethical principles, including-especially-beneficence, non-maleficence, and autonomy.

  1. Less than meets the eye: reappraising the clinical relevance of attentional bias in addiction.

    Christiansen, Paul; Schoenmakers, Tim M; Field, Matt

    2015-05-01

    Recent years have seen an explosion of interest in attentional bias in addiction, particularly its clinical relevance. Specifically, numerous articles claimed to demonstrate either that (1) attentional bias measured in treatment settings could predict subsequent relapse to substance use, or (2) direct modification of attentional bias reduced substance use and improved treatment outcomes. In this paper, we critically evaluate empirical studies that investigated these issues. We show that the evidence regarding both of these claims is decidedly mixed, and that many of the studies that appear to yield positive findings have serious methodological and statistical limitations. We contend that the available literature suggests that attentional bias for drug cues fluctuates within individuals because it is an output of the underlying motivational state at that moment in time, but there is no convincing evidence that it exerts a causal influence on substance use. Future research should make use of experience sampling methodology to characterise the clinical significance of fluctuations in attentional bias over time.

    Disease stratification, using phenotypic characterization performed either by hypothesis- or data-driven methods, was developed to improve clinical decisions. However, cluster analysis has not been used for allergic rhinitis. To define clusters in allergic rhinitis and to compare them with ARIA (Allergic Rhinitis and Its Impact on Asthma), a hypothesis-driven approach. A French observational prospective multicenter study (EVEIL: Echelle visuelle analogique dans la rhinite allergique) was carried out on 990 patients consulting general practitioners for allergic rhinitis and treated as per clinical practice. In this study, changes in symptom scores, visual analogue scales and quality of life were measured at baseline and after 14 days of treatment. A post hoc analysis was performed to identify clusters of patients with allergic rhinitis – using Ward's hierarchical method – and to define their clinical relevance at baseline and after 14 days of treatment. The cluster approach was compared to the ARIA approach. Patients were clustered into 4 phenotypes which partly followed the ARIA classes. These phenotypes differed in their disease severity including symptoms and quality of life. Physicians in real-life practice prescribed medication regardless of the phenotype and severity, with the exception of patients with ocular symptoms. Prescribed treatments were comparable in hypothesis- and data-driven analyses. The prevalence of uncontrolled patients during treatment was similar in the 4 clusters, but was significantly different according to the ARIA classes. Cluster analysis using demographic and clinical parameters only does not appear to add relevant information for disease stratification in allergic rhinitis. © 2015 S. Karger AG, Basel.

    Full Text Available The marine brown alga Halidrys siliquosa is known to produce compounds with antifouling activity against several marine bacteria. The aim of this study was to evaluate the antimicrobial and antibiofilm activity of organic extracts obtained from the marine brown alga H. siliquosa against a focused panel of clinically relevant human pathogens commonly associated with biofilm-related infections. The partially fractionated methanolic extract obtained from H. siliquosa collected along the shores of Co. Donegal; Ireland; displayed antimicrobial activity against bacteria of the genus Staphylococcus; Streptococcus; Enterococcus; Pseudomonas; Stenotrophomonas; and Chromobacterium with MIC and MBC values ranging from 0.0391 to 5 mg/mL. Biofilms of S. aureus MRSA were found to be susceptible to the algal methanolic extract with MBEC values ranging from 1.25 mg/mL to 5 mg/mL respectively. Confocal laser scanning microscopy using LIVE/DEAD staining confirmed the antimicrobial nature of the antibiofilm activity observed using the MBEC assay. A bioassay-guided fractionation method was developed yielding 10 active fractions from which to perform purification and structural elucidation of clinically-relevant antibiofilm compounds.

    Nicotine abuse is associated with variety of diseases including arrhythmias, most often atrial fibrillation (AF). Altered inward rectifier potassium currents including acetylcholine-sensitive current I K(Ach) are known to be related to AF pathogenesis. Since relevant data are missing, we aimed to investigate I K(Ach) changes at clinically relevant concentrations of nicotine. Experiments were performed by the whole cell patch clamp technique at 23 ± 1 °C on isolated rat atrial myocytes. Nicotine was applied at following concentrations: 4, 40 and 400 nM; ethanol at 20 mM (∼0.09%). Nicotine at 40 and 400 nM significantly activated constitutively active component of I K(Ach) with the maximum effect at 40 nM (an increase by ∼100%); similar effect was observed at -110 and -50 mV. Changes at 4 nM nicotine were negligible on average. Coapplication of 40 nM nicotine and 20 mM ethanol (which is also known to activate this current) did not show cumulative effect. In the case of acetylcholine-induced component of I K(Ach), a dual effect of nicotine and its correlation with the current magnitude in control were apparent: the current was increased by nicotine in the cells showing small current in control and vice versa. The effect of 40 and 400 nM nicotine on acetylcholine-induced component of I K(Ach) was significantly different at -110 and -50 mV. We conclude that nicotine at clinically relevant concentrations significantly increased constitutively active component of I K(Ach) and showed a dual effect on its acetylcholine-induced component, similarly as ethanol. Synchronous application of nicotine and ethanol did not cause additive effect.

  5. Colonization, pathogenicity, host susceptibility, and therapeutics for Staphylococcus aureus: what is the clinical relevance?

    Staphylococcus aureus is a human commensal that can also cause a broad spectrum of clinical disease. Factors associated with clinical disease are myriad and dynamic and include pathogen virulence, antimicrobial resistance, and host susceptibility. Additionally, infection control measures aimed at the environmental niches of S. aureus and therapeutic advances continue to impact upon the incidence and outcomes of staphylococcal infections. This review article focuses on the clinical relevance of advances in our understanding of staphylococcal colonization, virulence, host susceptibility, and therapeutics. Over the past decade key developments have arisen. First, rates of nosocomial methicillin-resistant S. aureus (MRSA) infections have significantly declined in many countries. Second, we have made great strides in our understanding of the molecular pathogenesis of S. aureus in general and community-associated MRSA in particular. Third, host risk factors for invasive staphylococcal infections, such as advancing age, increasing numbers of invasive medical interventions, and a growing proportion of patients with healthcare contact, remain dynamic. Finally, several new antimicrobial agents active against MRSA have become available for clinical use. Humans and S. aureus co-exist, and the dynamic interface between host, pathogen, and our attempts to influence these interactions will continue to rapidly change. Although progress has been made in the past decade, we are likely to face further surprises such as the recent waves of community-associated MRSA.

    In L5-S1 spondylolisthesis, it has been clearly demonstrated over the past decade that sacro-pelvic morphology is abnormal and that it can be associated to an abnormal sacro-pelvic orientation as well as to a disturbed global sagittal balance of the spine. The purpose of this article is to review the work done within the Spinal Deformity Study Group (SDSG) over the past decade, which has led to a classification incorporating this recent knowledge. The evidence presented has been derived from the analysis of the SDSG database, a multi-center radiological database of patients with L5-S1 spondylolisthesis, collected from 43 spine surgeons in North America and Europe. The classification defines 6 types of spondylolisthesis based on features that can be assessed on sagittal radiographs of the spine and pelvis: (1) grade of slip, (2) pelvic incidence, and (3) spino-pelvic alignment. A reliability study has demonstrated substantial intra- and inter-observer reliability similar to other currently used classifications for spinal deformity. Furthermore, health-related quality of life measures were found to be significantly different between the 6 types, thus supporting the value of a classification based on spino-pelvic alignment. The clinical relevance is that clinicians need to keep in mind when planning treatment that subjects with L5-S1 spondylolisthesis are a heterogeneous group with various adaptations of their posture. In the current controversy on whether high-grade deformities should or should not be reduced, it is suggested that reduction techniques should preferably be used in subjects with evidence of abnormal posture, in order to restore global spino-pelvic balance and improve the biomechanical environment for fusion.

    Full Text Available Background: Shoulder pain is the most common and well-documented site of musculoskeletal pain in elite swimmers. Structural abnormalities on magnetic resonance imaging (MRI of elite swimmers’ symptomatic shoulders are common. Little has been documented about the association between MRI findings in the asymptomatic shoulder versus the symptomatic shoulder.Objective: To assess clinically relevant MRI findings in the shoulders of symptomatic and asymptomatic elite swimmers.Method: Twenty (aged 16–23 years elite swimmers completed questionnaires on their swimming training, pain and shoulder function. MRI of both shoulders (n = 40 were performed and all swimmers were given a standardised clinical shoulder examination. Results: Both shoulders of 11 male and 9 female elite swimmers (n = 40 were examined. Eleven of the 40 shoulders were clinically symptomatic and 29 were asymptomatic. The most common clinical finding in both the symptomatic and asymptomatic shoulders was impingement during internal rotation, with impingement in 54.5% of the symptomatic shoulders and in 31.0% of the asymptomatic shoulders. The most common MRI findings in the symptomatic and asymptomatic shoulders were supraspinatus tendinosis (45.5% vs. 20.7%, subacromial subdeltoid fluid (45.5% vs. 34.5%, increased signal in the AC Joint (45.5% vs. 37.9% and AC joint arthrosis (36.4% vs. 34.5%. Thirty-nine (97.5% of the shoulders showed abnormal MRI features.Conclusion: MRI findings in the symptomatic and asymptomatic shoulders of young elite swimmers are similar and care should be taken when reporting shoulder MRIs in these athletes. Asymptomatic shoulders demonstrate manifold MRI abnormalities that may be radiologically significant but appear not to be clinically significant.

    Full Text Available Purpose: Coryneform or the non-diphtherial Corynebacterium species largely remains a neglected group with the traditional consideration of these organisms as contaminants. This concept, however, is slowly changing in the light of recent observations. This study has been done to find out the species distribution and antibiogram of various members of the clinically relevant Coryneform group, isolated from various clinical materials. Materials and Methods: One hundred and fourteen non-duplicate isolates of diphtheroids from various clinical isolates were selected for the study. The isolates were identified to the species level by using a battery of tests; and antimicrobial susceptibility was tested by using a combination of Clinical and Laboratory Standards Institute (CLSI and the British Society for Antimicrobial Chemotherapy (BSAC guidelines, in the absence of definitive CLSI guidelines. Results: Corynebacterium amycolatum was the predominant species (35.9% in our series followed by the CDC Group G organisms (15.7%. Each of the remaining 19 species comprised of less than 10% of the isolates. More than half the total isolates were resistant to the penicillins, erythromycin, and clindamycin; while excellent activity (all the strains being susceptible was shown by vancomycin, linezolid, and tigecycline. Chloramphenicol and tetracycline also had good activity in inhibiting more than 80% of the isolates. Multiply drug resistance was exhibited by all the species. Conclusion: This study was an attempt to establish the clinical significance of coryneform organisms. The high level of resistance shown by this group to some of the common antibacterial agents highlights the importance of processing these isolates in select conditions to guide the clinicians towards an appropriate therapy.

    The translocation t(8;21), leading to a fusion between the RUNX1 gene and the RUNX1T1 locus, was the first chromosomal translocation identified in cancer. Since the first description of this balanced rearrangement in a patient with acute myeloid leukemia (AML) in 1973, RUNX1 translocations and point mutations have been found in various myeloid and lymphoid neoplasms. In this chapter, we summarize the currently available data on the clinical relevance of core binding factor gene alterations in hematological disorders. In the first section, we discuss the prognostic implications of the core binding factor translocations RUNX1-RUNX1T1 and CBFB-MYH11 in AML patients. We provide an overview of the cooperating genetic events in patients with CBF-rearranged AML and their clinical implications, and review current treatment approaches for CBF AML and the utility of minimal residual disease monitoring. In the next sections, we summarize the available data on rare RUNX1 rearrangements in various hematologic neoplasms and the role of RUNX1 translocations in therapy-related myeloid neoplasia. The final three sections of the chapter cover the spectrum and clinical significance of RUNX1 point mutations in AML and myelodysplastic syndromes, in familial platelet disorder with associated myeloid malignancy, and in acute lymphoblastic leukemia.

  12. Polanyi's tacit knowing and the relevance of epistemology to clinical medicine.

    Henry, Stephen G

    2010-04-01

    Most clinicians take for granted a simple, reductionist understanding of medical knowledge that is at odds with how they actually practice medicine; routine medical decisions incorporate more complicated kinds of information than most standard accounts of medical reasoning suggest. A better understanding of the structure and function of knowledge in medicine can lead to practical improvements in clinical medicine. This understanding requires some familiarity with epistemology, the study of knowledge and its structure, in medicine. Michael Polanyi's theory of tacit knowing is advanced as the basis for developing a more accurate understanding of medical knowledge. Tacit knowing, which explores the taken-for-granted background knowledge that underlies all human knowing, is explained in detail with a focus on its relevance for clinical medicine. The implications of recognizing tacit knowing in medicine and medical decisions are discussed. These include the ability to explain the importance of the clinical encounter in medical practice, mechanisms for analysing patient and doctor as persons, and the need for humility given the uncertainty that the tacit dimension injects into all medical decisions. This more robust medical epistemology allows clinicians to better articulate the nature and importance of patient-centred care, to avoid pitfalls inherent in reductionist approaches to medical knowledge, and to think more clearly about the relationships between medicine and health care at the individual and population levels.

    This study examined whether gene-specific DNA variant databases for inherited diseases of the kidney fulfilled the Human Variome Project recommendations of being complete, accurate, clinically relevant and freely available. A recent review identified 60 inherited renal diseases caused by mutations in 132 genes. The disease name, MIM number, gene name, together with "mutation" or "database," were used to identify web-based databases. Fifty-nine diseases (98%) due to mutations in 128 genes had a variant database. Altogether there were 349 databases (a median of 3 per gene, range 0-6), but no gene had two databases with the same number of variants, and 165 (50%) databases included fewer than 10 variants. About half the databases (180, 54%) had been updated in the previous year. Few (77, 23%) were curated by "experts" but these included nine of the 11 with the most variants. Even fewer databases (41, 12%) included clinical features apart from the name of the associated disease. Most (223, 67%) could be accessed without charge, including those for 50 genes (40%) with the maximum number of variants. Future efforts should focus on encouraging experts to collaborate on a single database for each gene affected in inherited renal disease, including both unpublished variants, and clinical phenotypes. © 2014 WILEY PERIODICALS, INC.

    Myofascial pelvic pain is fraught with many unknowns. Is it the organs of the pelvis, is it the muscles of the pelvis, or is the origin of the pelvic pain from an extrapelvic muscle? Is there a single source or multiple? In this state of confusion what is the best way to manage the many symptoms that can be associated with myofascial pelvic pain. This article reviews current studies that attempt to answer some of these questions. More questions seem to develop as each study presents its findings.

    To determine the association between simplified pelvic organ prolapse quantification system(S-POP-Q)and the standard pelvic organ prolapse quantification system(POP-Q)in describing pelvic organ prolapse. This was an observational study. From Jan. 2010 to Jan. 2014, 256 subjects with pelvic floor disorder symptoms underwent two exams: a POP-Q exam and a S-POP-Q exam. For the S-POP-Q system, vaginal segments of the exam were defined using points Ba, Bp, C, and D. For the POP-Q system vaginal segments of the exam were defined using points Aa, Ba, Ap, Bp, C, and D. The inter-system consistency between the overall ordinal stages, the anterior vaginal wall stages, the posterior vaginal wall stages, the cervix stages, the posterior fornix or vaginal cuff stages from each two kind of exam were compared. The Kendall tau-b correlation coefficient for overall stage was 0.81, the Kendall tau-b correlation coefficients were 0.81, 0.81, 0.85, 0.88 for the anterior vaginal wall, for the posterior vaginal wall, for the cervix, for the posterior fornix or vaginal cuff, respectively. There is almost perfect association between S-POP-Q and POP-Q in describing pelvic organ prolapse.

    Despite the long held hypothesis that oxidant stress results in accumulated oxidative damage to cellular macromolecules and subsequently to aging and age-related chronic disease, it has been difficult to consistently define and specifically identify markers of oxidant stress that are consistently and directly linked to age and disease status. Inflammation because it is also linked to oxidant stress, aging, and chronic disease also plays an important role in understanding the clinical implications of oxidant stress and relevant markers. Much attention has focused on identifying specific markers of oxidative stress and inflammation that could be measured in easily accessible tissues and fluids (lymphocytes, plasma, serum). The purpose of this review is to discuss markers of oxidant stress used in the field as biomarkers of aging and age-related diseases, highlighting differences observed by race when data is available. We highlight DNA, RNA, protein, and lipid oxidation as measures of oxidative stress, as well as other well-characterized markers of oxidative damage and inflammation and discuss their strengths and limitations. We present the current state of the literature reporting use of these markers in studies of human cohorts in relation to age and age-related disease and also with a special emphasis on differences observed by race when relevant.

    Large-magnitude numerical distinctions (>10-fold) among drug responses of genetically contrasting cancers were crucial for guiding the development of some targeted therapies. Similar strategies brought epidemiological clues and prevention goals for genetic diseases. Such numerical guides, however, were incomplete or low magnitude for Fanconi anemia pathway (FANC) gene mutations relevant to cancer in FANC-mutation carriers (heterozygotes). We generated a four-gene FANC-null cancer panel, including the engineering of new PALB2/FANCN-null cancer cells by homologous recombination. A characteristic matching of FANCC-null, FANCG-null, BRCA2/FANCD1-null, and PALB2/FANCN-null phenotypes was confirmed by uniform tumor regression on single-dose cross-linker therapy in mice and by shared chemical hypersensitivities to various inter-strand cross-linking agents and γ-radiation in vitro. Some compounds, however, had contrasting magnitudes of sensitivity; a strikingly high (19- to 22-fold) hypersensitivity was seen among PALB2-null and BRCA2-null cells for the ethanol metabolite, acetaldehyde, associated with widespread chromosomal breakage at a concentration not producing breaks in parental cells. Because FANC-defective cancer cells can share or differ in their chemical sensitivities, patterns of selective hypersensitivity hold implications for the evolutionary understanding of this pathway. Clinical decisions for cancer-relevant prevention and management of FANC-mutation carriers could be modified by expanded studies of high-magnitude sensitivities.

    Full Text Available In view of the tremendous potential benefits of clinical information systems (CIS for the quality of patient care; it is hard to understand why not every CIS is embraced by its targeted users, the physicians. The aim of this study is to propose a framework for assessing hospital physicians' CIS-acceptance that can serve as a guidance for future research into this area. Hereto, a review of the relevant literature was performed in the ISI Web-of-Science database. Eleven studies were withheld from an initial dataset of 797 articles. Results show that just as in business settings, there are four core groups of variables that influence physicians' acceptance of a CIS: its usefulness and ease of use, social norms, and factors in the working environment that facilitate use of the CIS (such as providing computers/workstations, compatibility between the new and existing system.... We also identified some additional variables as predictors of CIS-acceptance.

    The study aim was to assess if an undersized mitral annuloplasty for functional mitral regurgitation (FMR) in dilated cardiomyopathy can determine a clinically relevant mitral stenosis during exercise. Both, rest and stress echocardiography were performed in 12 patients submitted to an undersized ring annuloplasty for FMR in dilated cardiomyopathy. The mean ring size was 27 +/- 1.3 mm. All patients were in NYHA functional classes I-II, were in stable sinus rhythm, and without significant residual mitral regurgitation (grade stroke volume (63 +/- 15 versus 77 +/- 14 ml, p FMR. Stress echocardiography represents a valuable tool to assess an appropriate cardiac response to exercise and to detect a significant exercise-induced pulmonary hypertension after undersized annuloplasty ring surgery.

    Full Text Available Conventional X-ray-based cystography uses radio-opaque materials, but this method uses harmful ionizing radiation and is not sensitive. In this study, we demonstrate nonionizing and noninvasive photoacoustic (PA and fluorescence (FL cystography using clinically relevant indocyanine green (ICG in vivo. After transurethral injection of ICG into rats through a catheter, their bladders were photoacoustically and fluorescently visualized. A deeply positioned bladder below the skin surface (i.e., ~1.5–5 mm was clearly visible in the PA and FL image using a laser pulse energy of less than 2 mJ/cm2 (1/15 of the safety limit. Then, the in vivo imaging results were validated through in situ studies. Our results suggest that dual modal cystography can provide a nonionizing and noninvasive imaging tool for bladder mapping.

    A thorough understanding of developmental cardiovascular physiology is essential for early recognition of cardiovascular compromise, selective screening of at-risk groups of neonates, and individualized management using pathophysiology-targeted interventions. Although we have gained a better understanding of the physiology and pathophysiology of postnatal cardiovascular transition over the past decade with the use of sophisticated methods to study neonatal hemodynamics, most aspects of neonatal hemodynamics remain incompletely understood. In addition, targeted therapeutic interventions of neonatal hemodynamic compromise have not been shown to improve mortality and clinically relevant outcomes. However, the recent development of comprehensive hemodynamic monitoring systems capable of non-invasive, continuous and simultaneous bedside assessment of cardiac output, organ blood flow, microcirculation, and tissue oxygen delivery has made sophisticated analysis of the obtained physiologic data possible and has created new research opportunities with the potential of direct implications to patient care.

    Full Text Available High throughput sequencing has accelerated knowledge on the oral microbiome. While the bacterial component of oral communities has been extensively characterized, the role of the fungal microbiota in the oral cavity is largely unknown. Interactions among fungi and bacteria are likely to influence oral health as exemplified by the synergistic relationship between Candida albicans and oral streptococci. In this perspective, we discuss the current state of the field of fungal-bacterial interactions in the context of the oral cavity. We highlight the need to conduct longitudinal clinical studies to simultaneously characterize the bacterial and fungal components of the human oral microbiome in health and during disease progression. Such studies need to be coupled with investigations using disease-relevant models to mechanistically test the associations observed in humans and eventually identify fungal-bacterial interactions that could serve as preventive or therapeutic targets for oral diseases.

    Advanced glycation end products (AGEs) are protein-bound compounds derived from glycaemic and oxidative stress that contain fluorescent properties, which can be non-invasively measured as skin autofluorescence (SAF) by the AGE Reader. SAF has been demonstrated to be a biomarker of cumulative skin AGEs and potentially may be a better predictor for the development of chronic complications and mortality in diabetes than glycated haemoglobin A1c. However, there are several confounding factors that should be assessed prior to its broader application: these include presence of other fluorescent compounds in the skin that might be measured (eg, fluorophores), skin pigmentation and use of skin creams. The aim of this article is to provide a theoretical background of this newly developed method, evaluate its clinical relevance and discuss the potential confounding factors that need further analysis.

    The surgical treatment of tetralogy of Fallot can be considered as a success story in the history of congenital heart diseases. Since the early outcome is no longer the main issue, the focus moved to the late sequelae of TOF repair, i.e. the pulmonary insufficiency and the secondary adaptation of the right ventricle. This review provides recent insights into the pathophysiological alterations of the right ventricle in relation to the reconstruction of the right ventricular outflow tract after repair of tetralogy of Fallot. Its clinical relevance is documented by addressing the policy changes regarding the optimal management at the time of surgical repair as well as properly defining criteria and timing for late pulmonary valve implantation.

    To assess MRI measures to quantify pelvic morphology that may predispose to ischiofemoral impingement (IFI). We hypothesized that patients with IFI have a wider interischial distance and an increased femoral neck angle compared with normal controls. The study was IRB-approved and complied with HIPAA guidelines. IFI was diagnosed based on clinical findings (hip or buttock pain) and ipsilateral edema of the quadratus femoris muscle on MRI. Control subjects did not report isolated hip/buttock pain and underwent MRI for surveillance of neoplasms or to exclude pelvic fractures. Two MSK radiologists measured the ischiofemoral (IF) and quadratus femoris (QF) distance, the ischial angle as a measure of inter-ischial distance, and the femoral neck angle. The quadratus femoris muscle was evaluated for edema. Groups were compared using ANOVA. Multivariate standard least-squares regression modeling was used to control for age and gender. The study group comprised 84 patients with IFI (53 ± 16 years, 73 female, 11 male) and 51 controls (52 ± 16 years, 33 female, 18 male). Thirteen out of 84 patients (15 %) had bilateral IFI. Patients with IFI had decreased IF and QF distance (p < 0.0001), increased ischial angle (p = 0.004), and increased femoral neck angle (p = 0.02) compared with controls, independent of age and gender. Patients with IFI have increased ischial and femoral neck angles compared with controls. These anatomical variations in pelvic morphology may predispose to IFI. MRI is a useful method of not only assessing the osseous and soft-tissue abnormalities associated with IFI, but also of quantifying anatomical variations in pelvic morphology that can predispose to IFI.

  10. Clinical relevance of the ROC and free-response paradigms for comparing imaging system efficacies.

    Observer performance studies are widely used to assess medical imaging systems. Unlike technical/engineering measurements observer performance include the entire imaging chain and the radiologist. However, the widely used receiver operating characteristic (ROC) method ignores lesion localisation information. The free-response ROC (FROC) method uses the location information to appropriately reward or penalise correct or incorrect localisations, respectively. This paper describes a method for improving the clinical relevance of FROC studies. The method consists of assigning appropriate risk values to the different lesions that may be present on a single image. A high-risk lesion is one that is critical to detect and act upon, and is assigned a higher risk value than a low-risk lesion, one that is relatively innocuous. Instead of simply counting the number of lesions that are detected, as is done in conventional FROC analysis, a risk-weighted count is used. This has the advantage of rewarding detections of high-risk lesions commensurately more than detections of lower risk lesions. Simulations were used to demonstrate that the new method, termed case-based analysis, results in a higher figure of merit for an expert who detects more high-risk lesions than a naive observer who detects more low-risk lesions, even though both detect the same total number of lesions. Conventional free-response analysis is unable to distinguish between the two types of observers. This paper also comments on the issue of clinical relevance of ROC analysis vs. FROC for tasks that involve lesion localisation.

    Recent findings in colon cancer cells indicate that inhibition of the mitochondrial H+-adenosine triphosphate (ATP) synthase by the ATPase inhibitory factor 1 (IF1) promotes aerobic glycolysis and a reactive oxygen species (ROS)-mediated signal that enhances proliferation and cell survival. Herein, we have studied the expression, biological relevance, mechanism of regulation and potential clinical impact of IF1 in some prevalent human carcinomas. We show that IF1 is highly overexpressed in most (>90%) of the colon (n=64), lung (n=30), breast (n=129) and ovarian (n=10) carcinomas studied as assessed by different approaches in independent cohorts of cancer patients. The expression of IF1 in the corresponding normal tissues is negligible. By contrast, the endometrium, stomach and kidney show high expression of IF1 in the normal tissue revealing subtle differences by carcinogenesis. The overexpression of IF1 also promotes the activation of aerobic glycolysis and a concurrent ROS signal in mitochondria of the lung, breast and ovarian cancer cells mimicking the activity of oligomycin. IF1-mediated ROS signaling activates cell-type specific adaptive responses aimed at preventing death in these cell lines. Remarkably, regulation of IF1 expression in the colon, lung, breast and ovarian carcinomas is exerted at post-transcriptional levels. We demonstrate that IF1 is a short-lived protein (t1/2 ∼100 min) strongly implicating translation and/or protein stabilization as main drivers of metabolic reprogramming and cell survival in these human cancers. Analysis of tumor expression of IF1 in cohorts of breast and colon cancer patients revealed its relevance as a predictive marker for clinical outcome, emphasizing the high potential of IF1 as therapeutic target.

  12. Per-beam, planar IMRT QA passing rates do not predict clinically relevant patient dose errors

    Purpose: The purpose of this work is to determine the statistical correlation between per-beam, planar IMRT QA passing rates and several clinically relevant, anatomy-based dose errors for per-patient IMRT QA. The intent is to assess the predictive power of a common conventional IMRT QA performance metric, the Gamma passing rate per beam. Methods: Ninety-six unique data sets were created by inducing four types of dose errors in 24 clinical head and neck IMRT plans, each planned with 6 MV Varian 120-leaf MLC linear accelerators using a commercial treatment planning system and step-and-shoot delivery. The error-free beams/plans were used as ''simulated measurements'' (for generating the IMRT QA dose planes and the anatomy dose metrics) to compare to the corresponding data calculated by the error-induced plans. The degree of the induced errors was tuned to mimic IMRT QA passing rates that are commonly achieved using conventional methods. Results: Analysis of clinical metrics (parotid mean doses, spinal cord max and D1cc, CTV D95, and larynx mean) vs IMRT QA Gamma analysis (3%/3 mm, 2/2, 1/1) showed that in all cases, there were only weak to moderate correlations (range of Pearson's r-values: -0.295 to 0.653). Moreover, the moderate correlations actually had positive Pearson's r-values (i.e., clinically relevant metric differences increased with increasing IMRT QA passing rate), indicating that some of the largest anatomy-based dose differences occurred in the cases of high IMRT QA passing rates, which may be called ''false negatives.'' The results also show numerous instances of false positives or cases where low IMRT QA passing rates do not imply large errors in anatomy dose metrics. In none of the cases was there correlation consistent with high predictive power of planar IMRT passing rates, i.e., in none of the cases did high IMRT QA Gamma passing rates predict low errors in anatomy dose metrics or vice versa

    Although visual inspection is the most commonly used method for caries detection, and consequently the most investigated, studies have not been concerned about the clinical relevance of this procedure. Therefore, we conducted a systematic review in order to perform a critical evaluation considering the clinical relevance and methodological quality of studies on the accuracy of visual inspection for assessing caries lesions. Two independent reviewers searched several databases through July 2013 to identify papers/articles published in English. Other sources were checked to identify unpublished literature. The eligible studies were those which (1) assessed the accuracy of the visual method for detecting caries lesions on occlusal, approximal or smooth surfaces, in primary or permanent teeth, (2) used a reference standard, and (3) reported data about sample size and accuracy of the methods. Aspects related to clinical relevance and the methodological quality of the studies were evaluated. 96 of the 5,578 articles initially identified met the inclusion criteria. In general, most studies failed in considering some clinically relevant aspects: only 1 included study validated activity status of lesions, no study considered its prognosis, 79 studies did not consider a clinically relevant outcome, and only 1 evaluated a patient-centred outcome. Concerning methodological quality, the majority of the studies presented a high risk of bias in sample selection. In conclusion, studies on the accuracy of the visual method for caries detection should consider clinically relevant outcomes besides accuracy; moreover, they should be conducted with higher methodological quality, mainly regarding sample selection.

    Full Text Available Abstract Background It has been shown in in-vitro experiments that "withdrawal" of tamoxifen inhibits growth of tumor cells. However, evidence is scarce when this is extrapolated into clinical context. We report our experience to verify the clinical relevance of "withdrawal therapy". Methods Breast cancer patients since 1998 who fulfilled the following criteria were selected from the departmental database and the case-notes were retrospectively reviewed: (1 estrogen receptor positive, operable primary breast cancer in elderly (age > 70 years, locally advanced or metastatic breast cancer; (2 disease deemed suitable for treatment by hormonal manipulation; (3 disease assessable by UICC criteria; (4 received "withdrawal" from a prior endocrine agent as a form of therapy; (5 on "withdrawal therapy" for ≥ 6 months unless they progressed prior. Results Seventeen patients with median age of 84.3 (53.7-92.5 had "withdrawal therapy" as second to tenth line of treatment following prior endocrine therapy using tamoxifen (n = 10, an aromatase inhibitor (n = 5, megestrol acetate (n = 1 or fulvestrant (n = 1. Ten patients (58.8% had clinical benefit (CB (complete response/partial response/stable disease ≥ 6 months with a median duration of Clinical Benefit (DoCB of 10+ (7-27 months. Two patients remain on "withdrawal therapy" at the time of analysis. Conclusion "Withdrawal therapy" appears to produce sustained CB in a significant proportion of patients. This applies not only to "withdrawal" from tamoxifen, but also from other categories of endocrine agents. "Withdrawal" from endocrine therapy is, therefore, a viable intercalating option between endocrine agents to minimise resistance and provide additional line of therapy. It should be considered as part of the sequencing of endocrine therapy.

    Actinomycosis is a rare suppurative disease due to Actinomyces species. These Gram-positive, non-acid fast anaerobic filamentous bacteria are normal inhabitants of the human body, tending to reside in the oropharynx and bowel but are occasionally found in the vagina. Pelvic actinomycosis is a rare bacterial disease in women. Clinical manifestations are various and non specific and may be acute or chronic. No consensus exists for treatment. We reviewed files and identified all five cases of pelvic actinomycosis managed at Obstetrics and Gynaecology department "A" at the Maternity Center of Tunis over an eight-year period (1998-2005). The women's average age was 39.2 years. One patient was menopausal and consulted for bleeding. The other four patients were younger and had all been using an intrauterine device (IUD) for contraception. They presented with acute clinical manifestations. Their main symptom was pelvic pain. Three women had fever, and two presented with urinary tract obstruction. All patients had surgery. A pelvic abscess was found in four cases. Laparoscopic management was possible in only one case. Laparotomy was necessary in the other four. Four women had adnexectomies, two with hysterectomy. Digestive complications occurred in three cases. Actinomycosis was diagnosed only after surgery, by the histological examination. This series confirms the difficulties encountered in the management of pelvic actinomycosis. We review the recent literature and describe the diagnostic and therapeutic procedures currently recommended. The relationship between pelvic actinomycosis and IUDs, the most common method of contraception in Tunisia, is clearly established. Clinical diagnosis of pelvic actinomycosis is difficult because the symptoms are non-specific. Laboratory tests can help by showing serious inflammation, however. Imaging findings are also non-specific and may suggest an abscess or an inflammatory or neoplastic process. Interventional radiology, specifically

    2015-01-01

    Background The β1,3-N-acetylglucosaminyltransferase-3 gene (B3GNT3) encodes a member of the B3GNT family that functions as the backbone structure of dimeric sialyl-Lewis A and is involved in L-selectin ligand biosynthesis, lymphocyte homing and lymphocyte trafficking. B3GNT3 has been implicated as an important element in the development of certain cancers. However, the characteristics of B3GNT3 in the development and progression of cancer remain largely unknown. Thus, our study aimed to investigate the expression pattern and the prognostic value of B3GNT3 in patients with early-stage cervical cancer. Methods The mRNA and protein levels of B3GNT3 expression were examined in eight cervical cancer cell lines and ten paired cervical cancer tumors, using real-time PCR and western blotting, respectively. Immunohistochemistry (IHC) was used to analyze B3GNT3 protein expression in paraffin-embedded tissues from 196 early-stage cervical cancer patients. Statistical analyses were applied to evaluate the association between B3GNT3 expression scores and clinical parameters, as well as patient survival. Results B3GNT3 expression was significantly upregulated in cervical cancer cell lines and lesions compared with normal cells and adjacent noncancerous cervical tissues. In the 196 cases of tested early-stage cervical cancer samples, the B3GNT3 protein level was positively correlated with high risk TYPES of human papillomavirus (HPV) infection (P = 0.026), FIGO stage (P cervical cancer patients. Conclusions Our study demonstrated that elevated B3GNT3 expression is associated with pelvic lymph node metastasis and poor outcome in early-stage cervical cancer patients. B3GNT3 may be a novel prognostic marker and therapeutic target for the treatment of cervical cancer. PMID:26709519

The definition of CP/CPPS includes genitourinary pain with or without voiding symptoms in the absence of uropathogenic bacteria, as detected by standard microbiological methods, or another identifiable cause such as malignancy. The efficacy of various medical therapies, has been evaluated in clinical studies, but evidence is lacking or conflicting. We compared Serenoa Repens in monotherapy versus Palmitoylethanolamide (PEA in combination with Alpha-lipoic acid (ALA and evaluated the efficacy of these treatments in patients with CP/CPPS. Methods: We conducted a randomized, single-blind trial. 44 patients diagnosed with CP/CPPS (mean age 41.32 ± 1.686 years were randomly assigned to treatment with Palmitoylethanolamide 300 mg plus Alpha-lipoic acid 300 mg (Peanase®, or Serenoa Repens at 320 mg. Three questionnaires (NIH-CPSI, IPSS and IIEF5 were administered at baseline and after 12 weeks of treatment in each group. Results: 12 week treatment with Peanase significantly improved the IPSS score compared to the same period of treatment with Serenoa Repens, and significantly reduced NIH-CPSI score. Similar results were observed in the different NIH-CPSI subscores break down. However, the same treatment did not result in significant improvement of the IIEF5 score. Both treatments did not produce undesired effects. Conclusions: The present results document the efficacy of an association of Palmitoylethanolamide (PEA and Alpha-lipoic acid (ALA administered for 12 weeks for treating patients with CP/CPPS, compared with Serenoa Repens monotherapy.

    To determine the clinical characteristics that indicate the presence of tubo-ovarian abscess (TOA) among patients with severe pelvic inflammatory disease (PID). An observational cohort study was performed from October 2011 to March 2013. The study included all patients with a diagnosis of TOA and PID admitted to a university hospital in Mexico. A complete medical history and physical examination were performed, and laboratory studies were reviewed. A logistic regression analysis was performed on variables with statistical significance. Overall, 26 patients with PID and TOA (TOA group) and 26 with PID without TOA (PID group) were included in the study. Significant differences between patients with TOA and PID were found with regard to the patients' age (39.3years vs 33.1years; P=0.04), educational level (only elementary, 13 [50%] vs 5 [19%]; P=0.14), presentation with fever (23 [88%] vs 16 [62%]; P=0.025), white blood cell count (21.8×10(9)/L vs 14.9×10(9)/L; P<0.001), number of deliveries (2.2 vs 1.1; P=0.01), and presence of diarrhea (16 [62%] vs 5 [19%]; P<0.001). The triad of fever, leukocytosis, and diarrhea was positively related to the presence of TOA. The triad of fever, leukocytosis, and diarrhea should alert clinicians to the possibility of TOA formation in patients with PID.

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

    Severe pelvic inflammatory disease and tuboovarian abscesses (TOAs) are common pelvic infections requiring inpatient admission. There are few large randomized trials guiding appropriate clinical management of TOA, including antibiotic selection and timing of surgical management and drainage. The pathogenesis, diagnosis, and management of severe pelvic inflammatory disease and TOA are summarized and reviewed from the most current literature.

    Limited sensitivity of existing assays has prevented investigation of whether Adriamycin-DNA adducts are involved in the anti-tumour potential of Adriamycin. Previous detection has achieved a sensitivity of a few Adriamycin-DNA adducts/10(4) bp DNA, but has required the use of supra-clinical drug concentrations. This work sought to measure Adriamycin-DNA adducts at sub-micromolar doses using accelerator mass spectrometry (AMS), a technique with origins in geochemistry for radiocarbon dating. We have used conditions previously validated (by less sensitive decay counting) to extract [(14)C]Adriamycin-DNA adducts from cells and adapted the methodology to AMS detection. Here we show the first direct evidence of Adriamycin-DNA adducts at clinically-relevant Adriamycin concentrations. [(14)C]Adriamycin treatment (25 nM) resulted in 4.4 +/- 1.0 adducts/10(7) bp ( approximately 1300 adducts/cell) in MCF-7 breast cancer cells, representing the best sensitivity and precision reported to date for the covalent binding of Adriamycin to DNA. The exceedingly sensitive nature of AMS has enabled over three orders of magnitude increased sensitivity of Adriamycin-DNA adduct detection and revealed adduct formation within an hour of drug treatment. This method has been shown to be highly reproducible for the measurement of Adriamycin-DNA adducts in tumour cells in culture and can now be applied to the detection of these adducts in human tissues.

    Dextromethorphan (DM) has been used for more than 50years as an over-the-counter antitussive. Studies have revealed a complex pharmacology of DM with mechanisms beyond blockade of N-methyl-d-aspartate (NMDA) receptors and inhibition of glutamate excitotoxicity, likely contributing to its pharmacological activity and clinical potential. DM is rapidly metabolized to dextrorphan, which has hampered the exploration of DM therapy separate from its metabolites. Coadministration of DM with a low dose of quinidine inhibits DM metabolism, yields greater bioavailability and enables more specific testing of the therapeutic properties of DM apart from its metabolites. The development of the drug combination DM hydrobromide and quinidine sulfate (DM/Q), with subsequent approval by the US Food and Drug Administration for pseudobulbar affect, led to renewed interest in understanding DM pharmacology. This review summarizes the interactions of DM with brain receptors and transporters and also considers its metabolic and pharmacokinetic properties. To assess the potential clinical relevance of these interactions, we provide an analysis comparing DM activity from in vitro functional assays with the estimated free drug DM concentrations in the brain following oral DM/Q administration. The findings suggest that DM/Q likely inhibits serotonin and norepinephrine reuptake and also blocks NMDA receptors with rapid kinetics. Use of DM/Q may also antagonize nicotinic acetylcholine receptors, particularly those composed of α3β4 subunits, and cause agonist activity at sigma-1 receptors.

    Against a backdrop of ever-changing diagnostic and treatment modalities, stakeholder perceptions (medical students, clinicians, anatomy educators) are crucial for the design of an anatomy curriculum which fulfils the criteria required for safe medical practice. This study compared perceptions of students, practising clinicians, and anatomy educators with respect to the relevance of anatomy education to medicine. A quantitative survey was administered to undergraduate entry (n = 352) and graduate entry students (n = 219) at two Irish medical schools, recently graduated Irish clinicians (n = 146), and anatomy educators based in Irish and British medical schools (n = 30). Areas addressed included the association of anatomy with medical education and clinical practice, mode of instruction, and curriculum duration. Graduate-entry students were less likely to associate anatomy with the development of professionalism, teamwork skills, or improved awareness of ethics in medicine. Clinicians highlighted the challenge of tailoring anatomy education to increase student readiness to function effectively in a clinical role. Anatomy educators indicated dissatisfaction with the time available for anatomy within medical curricula, and were equivocal about whether curriculum content should be responsive to societal feedback. The group differences identified in the current study highlight areas and requirements which medical education curriculum developers should be sensitive to when designing anatomy courses.

  12. Relevance of cellular to clinical electrophysiology in interpreting antiarrhythmic drug action.

    1989-12-01

    The usefulness of cellular electrophysiologic techniques in elucidating the fundamental actions of antiarrhythmic drugs is contrasted with their apparent lack of relevance to the selection of drugs for the treatment of particular arrhythmias. Clinical electrophysiologists employ different techniques, but their results may be explained in terms of cellular drug actions. The varying clinical effects of class IA, IB and IC agents are due to differences in the speed of their attachment to, and detachment from, sodium channels. The role of sympathetic activity in arrhythmogenesis is complex, but again readily explicable in terms of the electrophysiologic cellular actions of stimulation of the individual types of adrenoceptors (alpha 1, alpha 2, beta 1 and beta 2) and the distribution of these receptors, and of the longterm effects of sympathetic deprivation, either by antisympathetic drugs (class II) or by sympathetic denervation. Delayed repolarization (e.g., by class III drugs or prolonged beta blockade) is antiarrhythmic because it is homogeneous, despite the incidental prolongation of QT. If, however, QT is prolonged by heterogeneity of conduction or repolarization, or by partial sympathetic denervation (long QT syndrome or post myocardial infarction), this indicates increased risk of arrhythmia. Finally, the efficacy of calcium antagonists (class IV) in supraventricular arrhythmias is attributable to the cellular electrophysiologic characteristics of sinoatrial and atrioventricular nodal and transitional elements.

    Background Pulmonary hypertension (PH) is common in patients with maintenance hemodialysis (MHD) and is associated with high mortality. This study analyzed clinically relevant factors for pulmonary hypertension in MHD patients and the effect of serum pentraxin3 (PTX3) in the pathogenesis of PH to provide the basis for early diagnosis and treatment of MHD patients with PH. Material/Methods This study included 60 MHD patients (group A) and 30 healthy controls (group B). Group A was further divided into PH and non-PH groups. Clinical characteristics, auxiliary examination results and serum PTX3 level of the PH and non-PH groups were compared. Binary logistic regression was used to assess the risk factors for PH in MHD patients. ROC curve was applied to evaluate the diagnostic value of PTX3 in PH. Results The incidence rate of PH in MHD patients was 50%, and most presented as mild to moderate. Compared with the non-PH group, patients in PH group presented significantly longer atrial diameter, right ventricular diameter and main pulmonary artery diameter (PMHD patients. AUC of PTX3 was 0.721 (95%CI: 0.590–0.851, P=0.003). Conclusions The prevalence of PH was higher in MHD patients and mostly presented as mild to moderate. Such patients often developed heart structural changes and cardiac ultrasound was highly recommended. Serum PTX3 level was significantly elevated and could be used as a marker of PH in MHD patients.

    Pseudoxanthoma elasticum (PXE) is a multisystem ectopic mineralization disorder caused by mutations in the ABCC6 gene. Warfarin, a commonly used anticoagulant, is associated with increased mineralization of the arterial blood vessels and cardiac valves. We hypothesized that warfarin may accelerate ectopic tissue mineralization in PXE, with clinical consequences. To test this hypothesis, we developed a model in which Abcc6(-/-) mice, which recapitulate features of PXE, were fed a diet supplemented with warfarin and vitamin K1. Warfarin action was confirmed by significantly increased serum levels of oxidized vitamin K. For mice placed on a warfarin-containing diet, quantitative chemical and morphometric analyses revealed massive accumulation of mineral deposits in a number of tissues. Mice fed a warfarin-containing diet were also shown to have abundant uncarboxylated form of matrix Gla protein, which allowed progressive tissue mineralization to ensue. To explore the clinical relevance of these findings, 1747 patients with PXE from the approximately 4000 patients in the PXE International database were surveyed about the use of warfarin. Of the 539 respondents, 2.6% reported past or present use of warfarin. Based on the prevalence of PXE (approximately 1:50,000), thousands of patients with PXE worldwide may be at risk for worsening of PXE as a result of warfarin therapy.

  15. Clinical Relevance of Androgen Receptor Splice Variants in Castration-Resistant Prostate Cancer.

    2015-12-01

    Metastatic castration-resistant prostate cancer (mCRPC) currently benefits from a wealth of treatment options, yet still remains lethal in the vast majority of patients. It is becoming increasingly understood that this disease entity continues to evolve over time, acquiring additional and diverse resistance mechanisms with each subsequent therapy used. This dynamic relationship between treatment pressure and disease resistance can be challenging for the managing clinician. The recent discovery of alternate splice variants of the androgen receptor (AR) is one potential mechanism of escape in mCRPC, and recognizing this resistance mechanism might be important for optimal treatment selection for our patients. AR-V7 appears to be the most relevant AR splice variant, and early clinical data suggest that it is a negative prognostic marker in mCRPC. Emerging evidence also suggests that detection of AR-V7 may be associated with resistance to novel hormonal therapy (abiraterone and enzalutamide) but may be compatible with sensitivity to taxane chemotherapy (docetaxel and cabazitaxel). Adding to this complexity is the observation that AR-V7 is a dynamic marker whose status may change across time and depending on selective pressures induced by different therapies. Finally, it is possible that AR-V7 may represent a therapeutic target in mCRPC if drugs can be designed that degrade or inhibit AR splice variants or block their transcriptional activity. Several such agents (including galeterone, EPI-506, and bromodomain/BET inhibitors) are now in clinical development.

    This study was conducted to assess the seroprevalence and clinical relevance of Corynebacterium pseudotuberculosis, which is the causative agent of caseous lymphadenitis (CLA), in native Korean goats (Capra hircus coreanae). A total of 466 native Korean goats from 40 herds (11 to 12 samples per herd) were randomly selected throughout the nation and evaluated by direct palpation, bacterial isolation, ELISA, and PCR. In serological examinations, 267 (57.3 %) of the goats tested were positive against C. pseudotuberculosis. When seroprevalence was analyzed according to age, region, and season, statistically significant differences were observed in relation to all three parameters (P < 0.05). For clinical examination, the superficial lymph nodes of all goats were palpated to diagnose CLA. Pus samples taken from superficial abscesses were used for bacterial isolation. Among the 466 goats tested, 34 (7.3 %) were presumptively diagnosed with CLA, and C. pseudotuberculosis was isolated from 24 goats (70.6 % of goats with CLA lesions) whose infections were confirmed by PCR. Considering the high seroprevalence and bacterial isolation rate from most of the superficial CLA lesions, it is suspected that many internal CLA lesions exist in this goat population. These results suggest that C. pseudotuberculosis infection is widespread in native Korean goats, and appropriate control programs need to be established.

    In Central Europe, hazel (Corylus sp.) pollen is considered to be an important aeroallergen in early spring. This study examines hazel pollen levels in Poznań, western Poland, and the clinical relevance of this aeroallergen in the city. Corylus pollen data (1996-2010) were obtained by volumetric spore trap located near the centre of Poznań. Clinical data (2006-2010), i.e. skin prick test (SPT) and allergen-specific IgE measurements (asIgE), were supplied by the Allergy Diseases Diagnostic Centre in Poznań. Mean diurnal hazel pollen concentrations peaked around 14:00-16:00 when mean bi-hourly pollen concentrations were ~60 P m(-3). Onset of the hazel pollen season varied up to 87 days annually, and was significantly (r=-0.647; pHazel pollen has a detrimental effect on the allergic population of Poznań, with more than half of those sensitised to hazel pollen allergens showing symptoms of atopic dermatitis. Hazel pollen concentrations reach levels recognized as being able to induce allergy symptoms, especially in the afternoon and early evening when many people are returning home from work. The cross-reactivity with other members of the Fagales order also increases the allergenic potential of hazel pollen.

    The objectives of this study were to use magnetic resonance (MR) imaging to evaluate the prevalence, size, location, and clinical relevance of tendon rerupture following complete repair of full-thickness rotator cuff tear (RCT). A total of 78 surgically proven full-thickness rotator cuff tears in 74 patients were retrospectively included in the study. Clinical assessment was performed using the University of California at Los Angeles score. Postoperative MR imaging was evaluated to determine prevalence, size, and location of tendon rerupture. At a mean 48.4 months' follow-up, 62 shoulders (79.5%) had favorable outcomes and 45 shoulders (57.6%) showed rerupture on MR imaging studies. Reruptures were significantly more prevalent among patients with intermediate-to-bad outcomes (81.3%), with surgically demonstrated two-tendon tears (78.9%) or three-tendon tears (100%), and with preoperative fatty degeneration of the supraspinatus muscle greater than 1 (91.6%). Reruptures were also significantly larger in those subgroups. Complete repair of RCT of all sizes may have favorable outcomes in a significant proportion of patients in spite of a high prevalence of reruptures. Preoperative tear size and degree of muscle fatty degeneration influence the prevalence and rerupture size. After repair of supraspinatus tears, reruptures tend to invade the posterior aspect of the tendon. (orig.)

    Purpose: To evaluate the toxicity and clinical outcome in patients with locally advanced cervical cancer (LACC) treated with whole pelvic conventional radiation therapy (WP-CRT) versus intensity modulated radiation therapy (WP-IMRT). Methods and Materials: Between January 2010 and January 2012, 44 patients with International Federation of Gynecology and Obstetrics (FIGO 2009) stage IIB-IIIB squamous cell carcinoma of the cervix were randomized to receive 50.4 Gy in 28 fractions delivered via either WP-CRT or WP-IMRT with concurrent weekly cisplatin 40 mg/m{sup 2}. Acute toxicity was graded according to the Common Terminology Criteria for Adverse Events, version 3.0, and late toxicity was graded according to the Radiation Therapy Oncology Group system. The primary and secondary endpoints were acute gastrointestinal toxicity and disease-free survival, respectively. Results: Of 44 patients, 22 patients received WP-CRT and 22 received WP-IMRT. In the WP-CRT arm, 13 patients had stage IIB disease and 9 had stage IIIB disease; in the IMRT arm, 12 patients had stage IIB disease and 10 had stage IIIB disease. The median follow-up time in the WP-CRT arm was 21.7 months (range, 10.7-37.4 months), and in the WP-IMRT arm it was 21.6 months (range, 7.7-34.4 months). At 27 months, disease-free survival was 79.4% in the WP-CRT group versus 60% in the WP-IMRT group (P=.651), and overall survival was 76% in the WP-CRT group versus 85.7% in the WP-IMRT group (P=.645). Patients in the WP-IMRT arm experienced significantly fewer grade ≥2 acute gastrointestinal toxicities (31.8% vs 63.6%, P=.034) and grade ≥3 gastrointestinal toxicities (4.5% vs 27.3%, P=.047) than did patients receiving WP-CRT and had less chronic gastrointestinal toxicity (13.6% vs 50%, P=.011). Conclusion: WP-IMRT is associated with significantly less toxicity compared with WP-CRT and has a comparable clinical outcome. Further studies with larger sample sizes and longer follow-up times are warranted to justify

    Preeclampsia, a cardiovascular disorder of late pregnancy, is characterized as a low-renin hypertensive state relative to normotensive pregnancy. Because other nonpregnant low-renin hypertensive disorders often exhibit and are occasionally dependent on elevated arginine vasopressin (AVP) secretion, we hypothesized a possible use for plasma AVP measurements in the prediction of preeclampsia. Copeptin is an inert prosegment of AVP that is secreted in a 1:1 molar ratio and exhibits a substantially longer biological half-life compared with AVP, rendering it a clinically useful biomarker of AVP secretion. Copeptin was measured throughout pregnancy in maternal plasma from preeclamptic and control women. Maternal plasma copeptin was significantly higher throughout preeclamptic pregnancies versus control pregnancies. While controlling for clinically significant confounders (age, body mass index, chronic essential hypertension, twin gestation, diabetes mellitus, and history of preeclampsia) using multivariate regression, the association of higher copeptin concentration and the development of preeclampsia remained significant. Receiver operating characteristic analyses reveal that as early as the sixth week of gestation, elevated maternal plasma copeptin concentration is a highly significant predictor of preeclampsia throughout pregnancy. Finally, chronic infusion of AVP during pregnancy (24 ng per hour) is sufficient to phenocopy preeclampsia in C57BL/6J mice, causing pregnancy-specific hypertension, renal glomerular endotheliosis, proteinuria, and intrauterine growth restriction. These data implicate AVP release as a novel predictive biomarker for preeclampsia very early in pregnancy, identify chronic AVP infusion as a novel and clinically relevant model of preeclampsia in mice, and are consistent with a potential causative role for AVP in preeclampsia in humans. © 2014 American Heart Association, Inc.

    Efficacious therapy is of utmost importance to save lives and prevent bacterial resistance in critically ill patients. This review summarizes pharmacokinetic (PK) and pharmacodynamic (PD) modeling methods to optimize clinical care of critically ill patients in empiric and individualized therapy. While these methods apply to all therapeutic areas, we focus on antibiotics to highlight important applications, as emergence of resistance is a significant problem. Nonparametric and parametric population PK modeling, multiple-model dosage design, Monte Carlo simulations, and Bayesian adaptive feedback control are the methods of choice to optimize therapy. Population PK can estimate between patient variability and account for potentially increased clearances and large volumes of distribution in critically ill patients. Once patient- specific PK data become available, target concentration intervention and adaptive feedback control algorithms can most precisely achieve target goals such as clinical cure of an infection or resistance prevention in stable and unstable patients with rapidly changing PK parameters. Many bacterial resistance mechanisms cause PK/PD targets for resistance prevention to be usually several-fold higher than targets for near-maximal killing. In vitro infection models such as the hollow fiber and one-compartment infection models allow one to study antibiotic-induced bacterial killing and emergence of resistance of mono- and combination therapies over clinically relevant treatment durations. Mechanism-based (and empirical) PK/PD modeling can incorporate effects of the immune system and allow one to design innovative dosage regimens and prospective validation studies. Mechanism-based modeling holds great promise to optimize mono- and combination therapy of anti-infectives and drugs from other therapeutic areas for critically ill patients.

  2. New insights of an old defense system: structure, function, and clinical relevance of the complement system.

    2011-01-01

    The complement system was discovered a century ago as a potent defense cascade of innate immunity. After its first description, continuous experimental and clinical research was performed, and three canonical pathways of activation were established. Upon activation by traumatic or surgical tissue damage, complement reveals beneficial functions of pathogen and danger defense by sensing and clearing injured cells. However, the latest research efforts have provided a more distinct insight into the complement system and its clinical subsequences. Complement has been shown to play a significant role in the pathogenesis of various inflammatory processes such as sepsis, multiorgan dysfunction, ischemia/reperfusion, cardiovascular diseases and many others. The three well-known activation pathways of the complement system have been challenged by newer findings that demonstrate direct production of central complement effectors (for example, C5a) by serine proteases of the coagulation cascade. In particular, thrombin is capable of producing C5a, which not only plays a decisive role on pathogens and infected/damaged tissues, but also acts systemically. In the case of uncontrolled complement activation, "friendly fire" is generated, resulting in the destruction of healthy host tissue. Therefore, the traditional research that focuses on a mainly positive-acting cascade has now shifted to the negative effects and how tissue damage originated by the activation of the complement can be contained. In a translational approach including structure-function relations of this ancient defense system, this review provides new insights of complement-mediated clinical relevant diseases and the development of complement modulation strategies and current research aspects.

    Full Text Available INTRODUCTION : Percutaneous nephrolithotomy (PCNL is the most frequently performed surgery for stone disease at our institution. Nearly 100 PCNL procedures are being performed in a year at our institution. Septicemia following PCNL can be catastrophic despite sterile preoperative urine and prophylactic antibiotics. Infected stones, obstructed kidneys , and comorbidit y have been held responsible. In this study we analyzed various culture specimens, namely Mid - stream urine (MSU, renal pelvic urine and crushed stones. MATERIALS AND METHODS : We performed a prospective clinical study in all our patients undergoing PCNL b etween January 2013 and December 2014. MSU was sent for culture and sensitivity testing (C&S one day prior to surgery. Percutaneous access into the ipsilateral pelvicaliceal system is achieved under image intensification using a fine, 14 gauge Kellet need le. Urine from the pelvicaliceal system is first aspirated and sent as pelvic urine C&S. Stone fragments are collected to be proces0sed for C&S. The data collected were divided into 3 main groups, that is MSU C&S, pelvic urine C&S and stone C&S. RESULTS : A total of 83 patients were included in the study, of this MSU C&S was positive in 9/83 (10.8% patients, Pelvic C&S in 10 /73 (13.7% patients and Stone C&S in 25/83 (30.1% patients. Out of 25 cases of stone culture positive patients 17 patients develope d Systemic Inflammatory Response Syndrome (SIRS but only 2 patients developed SIRS in MSU C & S positive patients. CONCLUSIONS: The results of our study suggest that positive stone C&S is the better predictor of potential urosepsis than MSU. Stone cultur e is available only after surgery but appears to be the best guide for antibiotic therapy in case of sepsis. So the routine collection of stone for C&S will be beneficial

    Digital pathology systems typically consist of a slide scanner, processing software, visualization software, and finally a workstation with display for visualization of the digital slide images. This paper studies whether digital pathology images can look different when presenting them on different display systems, and whether these visual differences can result in different perceived contrast of clinically relevant features. By analyzing a set of four digital pathology images of different subspecialties on three different display systems, it was concluded that pathology images look different when visualized on different display systems. The importance of these visual differences is elucidated when they are located in areas of the digital slide that contain clinically relevant features. Based on a calculation of dE2000 differences between background and clinically relevant features, it was clear that perceived contrast of clinically relevant features is influenced by the choice of display system. Furthermore, it seems that the specific calibration target chosen for the display system has an important effect on the perceived contrast of clinically relevant features. Preliminary results suggest that calibrating to DICOM GSDF calibration performed slightly worse than sRGB, while a new experimental calibration target CSDF performed better than both DICOM GSDF and sRGB. This result is promising as it suggests that further research work could lead to better definition of an optimized calibration target for digital pathology images resulting in a positive effect on clinical performance.

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

    Purpose Pelvic inflammatory disease (PID) disproportionately affects adolescent and young adult (AYA) women and can negatively influence reproductive health trajectories. Few randomized controlled trials (RCTs) have focused on strategies to improve outpatient adherence or to reduce reproductive morbidity in this population. This paper describes the research methods and preliminary effectiveness of recruitment, retention, and intervention strategies employed in a novel RCT designed to test a technology-enhanced community-health nursing (TECH-N) intervention among urban AYA with PID. Methods AYA women aged 13–25 years were recruited during acute PID visits in outpatient clinics and emergency departments (ED) to participate in this IRB-approved trial. Participants completed an audio-computerized self-interview (ACASI), provided vaginal specimens, and were randomized to standard treatment or the intervention. Intervention participants received text-messaging support for 30 days and a community health nurse (CHN) interventionist performed a home visit with clinical assessment within 5 days after enrollment. All patients received a full course of medications and completed research visits at 14-days (adherence), 30 days and 90 days with by an outreach worker. STI testing performed at the 30-and 90-day visits. Exploratory analyses using descriptive statistics were conducted to examine recruitment, retention, and follow-up data to test the overall design of the intervention. Results In the first 48 months, 64% of 463 patients were eligible for the study and 81.2% of 293 eligible patients were recruited for the study (63.3%); 238 (81.2%) of eligible patients were enrolled. Most participants were African American (95.6%) with a mean age of 18.6 (2.3). Ninety-four percent of individuals assigned to the TECH-N intervention completed the nursing visits. All completed visits have been within the 5-day window and over 90% of patients in both arms have been retained over the 3

    Full Text Available Now pelvic inflammatory disease (PID is one of the most urgent problems in modern gynecology. Pelvic inflammatory diseases (PID have a leading position not only in the structure of gynecological morbidity, but also are the most frequent cause of damage to the reproductive health of women, thereby creating health, social and economic problems. In modern conditions, inflammatory diseases of the genitals are characterized by several features: multifocal inflammatory lesion; the lack of specific clinical symptoms; transformation of clinical finding toward obligated and atypical forms which causes significant difficulties in diagnosis. Latent, obligated, indolent, asymptomatic, subclinical, and in English literature - "dumb, atypical or unrecognized" inflammation is 60% of all PID (V.I. Kulakov, 2005, A.P. Nikonov, 2006, Bezbakh I.V., 2006, Lineva O.I., 2006, Kovalev, L.A., 2010, Sweet R.L., 2009 Serov V.N., 2011. In 2012 European Guideline IUSTI / WHO on keeping patients with pelvic inflammatory disease was published. Unfortunately, conventional methods for routine laboratory studies often have a diagnostic value only in patients with severe clinical manifestations of the disease. Thus, to assess the severity of the inflammatory process only by conventional clinical criteria are currently not possible. Search of diagnostic criteria based on objective indicators, is highly relevant [1], [3].

    Background Helminth infections can negatively affect the immunologic host control, which may increase the risk of progression from latent Mycobacterium tuberculosis infection to tuberculosis (TB) disease and alter the clinical presentation of TB. We assessed the prevalence and determined the clinical relevance of helminth co-infection among TB patients and household contact controls in urban Tanzania. Methodology Between November 2013 and October 2015, we enrolled adult (≥18 years) sputum smear-positive TB patients and household contact controls without TB during an ongoing TB cohort study in Dar es Salaam, Tanzania. We used Baermann, FLOTAC, Kato-Katz, point-of-care circulating cathodic antigen, and urine filtration to diagnose helminth infections. Multivariable logistic regression models with and without random effects for households were used to assess for associations between helminth infection and TB. Principal findings A total of 597 TB patients and 375 household contact controls were included. The median age was 33 years and 60.2% (585/972) were men. The prevalence of any helminth infection among TB patients was 31.8% (190/597) and 25.9% (97/375) among controls. Strongyloides stercoralis was the predominant helminth species (16.6%, 161), followed by hookworm (9.0%, 87) and Schistosoma mansoni (5.7%, 55). An infection with any helminth was not associated with TB (adjusted odds ratio (aOR) 1.26, 95% confidence interval (CI): 0.88–1.80, p = 0.22), but S. mansoni infection was (aOR 2.15, 95% CI: 1.03–4.45, p = 0.040). Moreover, S. mansoni infection was associated with lower sputum bacterial load (aOR 2.63, 95% CI: 1.38–5.26, p = 0.004) and tended to have fewer lung cavitations (aOR 0.41, 95% CI: 0.12–1.16, p = 0.088). Conclusions/Significance S. mansoni infection was an independent risk factor for active TB and altered the clinical presentation in TB patients. These findings suggest a role for schistosomiasis in modulating the pathogenesis of human TB

    The category 'eating disorder 'not otherwise specified'' (EDNOS) in DSM-IV is restricted to eating disorders of clinical severity that do not completely fulfil the criteria for anorexia and bulimia nervosa. The EDNOS category is, by definition, often regarded as a a residual category and in principle designed to incorporate a small group of patients with atypical characteristics. Health insurance companies argue that the treatment of patients diagnosed with EDNOS should not be treated in mental health institutions and therefore should not get their treatment costs reimbursed by the insurance companies. The most important argument of the insurance companies is that patients in the EDNOS category do not display serious psychiatric symptoms. The aim of this paper is to show that EDNOS is an eating disorder category of clinical relevance. The article provides a critical overview of literature on EDNOS which studies the prevalence, severity and course of the disorder. We also discuss to what extent the fifth version of dsm solves the problems relating to this residual category. We reviewed the literature. The classification given in DSM-IV is not an accurate reflection of clinical reality. Half of the patients presenting with an eating disorder and seeking treatment do meet the criteria for EDNOS. The duration and the severity of eating disorder psychopathology, the presence of comorbidity, the mortality, and the use of the mental health care services by individuals with an eating disorder appear to be very similar in EDNOS patients and in patients with anorexia and bulimia nervosa. Eating disorder classifications can be regarded as snapshots taken throughout the course of an illness. Over of the years patients can be afflicted with various subtypes of an eating disorder. DSM-5 places fewer patients in the EDNOS category that did DSM-IV. In the latest version of dsm, namely DSM-5, the number of patients with an eating disorder classified as EDNOS has declined. There

    Compression of the lateral femoral cutaneous nerve (LFCN), known as meralgia paresthetica (MP), is common. We investigated the topographic anatomy of the LFCN focusing on the inguinal ligament and adjacent structures. Distances from various bony and soft-tissue landmarks to the LFCN were investigated in 33 formalin-embalmed cadavers. The mean distance from the anterior superior iliac spine (ASIS) to the LFCN was 8.8 mm. In approximately 90% of cases, the LFCN lay <2 cm from the medial tip of the ASIS, whereas, in 76% of cases, it was <1 cm away. The mean angle between the inguinal ligament and LFCN was 83.3°. We determined the variability of the location of the LFCN at the boundary between the pelvic and femoral portions. The reported results will be helpful for diagnosis and treatment of MP.

    Neural networks (NN) are typically developed to minimize the squared difference between the network's output and the target value for a set of training patterns; namely the mean squared error (MSE). However, lower MSE does not necessarily translate into a clinically more useful decision model. The purpose of this study was to investigate the particle swarm optimization (PSO) algorithm as an alternative way of NN optimization with clinically relevant objective functions (e.g., ROC and partial ROC area indices). The PSO algorithm was evaluated with respect to a NN-based CAD system developed to discriminate mammographic regions of interest (ROIs) that contained masses from normal regions based on 8 computer-extracted morphology-oriented features. Neural networks were represented as points (particle locations) in a D-dimensional search/optimization space where each dimension corresponded to one adaptable NN parameter. The study database of 1,337 ROIs (681 with masses, 656 normal) was split into two subsets to implement two-fold cross-validation sampling scheme. Neural networks were optimized with the PSO algorithm and the following objective functions (1) MSE, (2) ROC area index AUC, and (3) partial ROC area indices TPFAUC with TPF=0.90 and TPF=0.98. For comparison, performance of neural networks of the same architecture trained with the traditional backpropagation algorithm was also evaluated. Overall, the study showed that when the PSO algorithm optimized network parameters using a particular training objective, the NN test performance was superior with respect to the corresponding performance index. This was particularly true for the partial ROC area indices where statistically significant improvements were observed.

    Full Text Available Background. In Central Europe, hazel ([i]Corylus[/i] sp. pollen is considered to be an important aeroallergen in early spring. Objective. This study examines hazel pollen levels in Poznań, western Poland, and the clinical relevance of this aeroallergen in the city. Methods. [i]Corylus[/i] pollen data (1996–2010 were obtained by volumetric spore trap located near the centre of Poznań. Clinical data (2006–2010, i.e. skin prick test (SPT and allergen-specific IgE measurements (asIgE, were supplied by the Allergy Diseases Diagnostic Centre in Poznań. Results. Mean diurnal hazel pollen concentrations peaked around 14:00–16:00 when mean bi-hourly pollen concentrations were ~60 P m-3. Onset of the hazel pollen season varied up to 87 days annually, and was significantly (r=–0.647; p<0.01 related to mean maximum temperature during late December. SPT data revealed that ~11% of allergy patients had positive skin reactions to [i]Corylus[/i] pollen allergens, and most of these (94.4% reacted to pollen allergens from other members of the Betulaceae family – alder or birch. Of those sensitized, 53% suffered from atopic dermatitis. Of patients examined for serum asIgE, 26.0% had asIgE measurements in classes 5 and 6. Conclusions. Hazel pollen has a detrimental effect on the allergic population of Poznań, with more than half of those sensitised to hazel pollen allergens showing symptoms of atopic dermatitis. Hazel pollen concentrations reach levels recognized as being able to induce allergy symptoms, especially in the afternoon and early evening when many people are returning home from work. The cross-reactivity with other members of the Fagales order also increases the allergenic potential of hazel pollen.

    The comorbidity of headache and psychiatric disorders is a well-recognized clinical phenomenon warranting further systematic research. Affective disorders occur with at least three-fold greater frequency among migraineurs than among the general population, and the prevalence increases in clinical populations, especially with chronic daily headache. When present, psychiatric comorbidity complicates headache management and portends a poorer prognosis for headache treatment. However, the relationship between headache and psychopathology has historically been misunderstood, and measures of psychopathology have not always met the standard of formal Diagnostic and Statistical Manual of Mental Disorders, 4th ed. (DSM-IV) criteria. In some cases, headache has been inappropriately attributed to psychological or psychiatric features, based on anecdotal observations. The challenge for future studies is to employ research methods and designs that accurately identify and classify the subset of headache patients with psychiatric disorders, evaluate their impact on headache symptoms and treatment, and identify optimal behavioral and pharmacologic treatment strategies. This article offers methodological considerations and recommendations for future research including: (i) ascribing dual-International Classification of Headache Disorders, 2nd ed. (ICHD-2) headache and DSM-IV psychiatric diagnoses according to reliable and valid diagnostic criteria, (ii) differentiating subclinical levels of depression and anxiety from major psychiatric disorders, (iii) encouraging validation studies of the recently published ICHD-2 diagnoses for "headache attributed to psychiatric disorder," (iv) expanding epidemiological research to address the range of DSM-IV Axis I and II psychiatric diagnoses among various headache populations, (v) identifying relevant psychiatric and behavioral mediator/moderator variables, and (vi) developing empirically based screening and treatment algorithms.

    An Expert Panel group of scientists and clinicians met to consider several aspects related to non-fasting and postprandial triglycerides (TGs) and their role as risk factors for cardiovascular disease (CVD). In this context, we review recent epidemiological studies relevant to elevated non-fasting TGs as a risk factor for CVD and provide a suggested classification of non-fasting TG concentration. Secondly, we sought to describe methodologies to evaluate postprandial TG using a fat tolerance test (FTT) in the clinic. Thirdly, we discuss the role of non-fasting lipids in the treatment of postprandial hyperlipemia. Finally, we provide a series of clinical recommendations relating to non-fasting TGs based on the consensus of the Expert Panel: 1). Elevated non-fasting TGs are a risk factor for CVD. 2). The desirable non-fasting TG concentration is fast and should consist of 75 g of fat, 25 g of carbohydrates and 10 g of protein. 4). A single TG measurement 4 h after a FTT meal provides a good evaluation of the postprandial TG response. 5). Preferably, subjects with non-fasting TG levels of 1-2 mmol/l (89-180 mg/dl) should be tested with a FTT. 6). TG concentration ≤ 2.5 mmol/l (220 mg/dl) at any time after a FTT meal should be considered as a desirable postprandial TG response. 7). A higher and undesirable postprandial TG response could be treated by aggressive lifestyle modification (including nutritional supplementation) and/or TG lowering drugs like statins, fibrates and nicotinic acid.

    Little evidence exists examining cardiovascular risk factors among Asian Americans and how social determinants such as nativity status and education pattern risk in the United States (U.S.) context. We used the 2011-2014 National Health and Nutrition Examination Survey, which purposely oversampled Asian Americans from 2011 to 2014, and examined prevalence of Type II diabetes, smoking and obesity for Asian Americans (n=1363) and non-Latino Whites (n=4121). We classified Asian Americans as U.S. or foreign-born and by years in the U.S. Obesity status was based on standard body mass index (BMI) cut points of ≥30kg/m(2) and Asian-specific cut points (BMI≥25kg/m(2)) that may be more clinically relevant for this population. We fit separate logistic regression models for each outcome using complex survey design methods and tested for the joint effect of race, nativity and education on each outcome.Diabetes and obesity prevalence (applying Asian-specific BMI cut points) were higher among Asian Americans when compared to non-Latino Whites but smoking prevalence was lower. These patterns remained in fully adjusted models and showed small increases with longer duration in the U.S. Joint effects models showed higher odds of prevalent Type II diabetes and obesity (Asian-specific) for foreign-born Asians, regardless of years in the U.S. and education, when compared to non-Latino Whites with high education. Smoking models showed significant interaction effects between race and education for non-Latino Whites only. Our study supports the premise that social as well as clinical factors should be considered when developing health initiatives for Asian Americans.

    Full Text Available Abstract Background A strong dose-volume relationship exists between the amount of small bowel receiving low- to intermediate-doses of radiation and the rates of acute, severe gastrointestinal toxicity, principally diarrhea. There is considerable interest in the application of highly conformal treatment approaches, such as intensity-modulated radiation therapy (IMRT, to reduce dose to adjacent organs-at-risk in the treatment of carcinoma of the rectum. Therefore, we performed a comprehensive dosimetric evaluation of IMRT compared to 3-dimensional conformal radiation therapy (3DCRT in standard, preoperative treatment for rectal cancer. Methods Using RTOG consensus anorectal contouring guidelines, treatment volumes were generated for ten patients treated preoperatively at our institution for rectal carcinoma, with IMRT plans compared to plans derived from classic anatomic landmarks, as well as 3DCRT plans treating the RTOG consensus volume. The patients were all T3, were node-negative (N = 1 or node-positive (N = 9, and were planned to a total dose of 45-Gy. Pairwise comparisons were made between IMRT and 3DCRT plans with respect to dose-volume histogram parameters. Results IMRT plans had superior PTV coverage, dose homogeneity, and conformality in treatment of the gross disease and at-risk nodal volume, in comparison to 3DCRT. Additionally, in comparison to the 3DCRT plans, IMRT achieved a concomitant reduction in doses to the bowel (small bowel mean dose: 18.6-Gy IMRT versus 25.2-Gy 3DCRT; p = 0.005, bladder (V40Gy: 56.8% IMRT versus 75.4% 3DCRT; p = 0.005, pelvic bones (V40Gy: 47.0% IMRT versus 56.9% 3DCRT; p = 0.005, and femoral heads (V40Gy: 3.4% IMRT versus 9.1% 3DCRT; p = 0.005, with an improvement in absolute volumes of small bowel receiving dose levels known to induce clinically-relevant acute toxicity (small bowel V15Gy: 138-cc IMRT versus 157-cc 3DCRT; p = 0.005. We found that the IMRT treatment volumes were typically larger than that

    Full Text Available Bacterial isolates are often transported between laboratories for research and diagnostic purposes. Silica desiccant packets (SDPs, which are inexpensive and do not require freezing, were evaluated for storage and recovery of bacterial isolates. Conditions such as inoculum size, swab type and temperature of storage were investigated using ten Streptococcus pneumoniae isolates. The optimized protocol was then tested using 49 additional S. pneumoniae isolates representing 40 serogroups. Overall, S. pneumoniae growth was considered satisfactory (>100 colony forming units for 98/109 (89.9% and 20/20 (100% swabs after 14 days at room temperature or 28 days at 4° C, respectively. Storage in SDPs did not impact on the ability of S. pneumoniae isolates to be subsequently serotyped. When the survival of nine other clinically relevant bacterial species was tested, seven were viable after 28 days at room temperature, the exceptions being Neisseria gonorrhoeae and Haemophilus influenzae. SDPs are suitable for transport and short-term storage of bacterial species including S. pneumoniae.

    Advances in understanding many of the fundamental mechanisms of cancer progression have led to the development of molecular targeted therapies. While molecular targeted therapeutics continue to improve the outcome for cancer patients, tumor heterogeneity among patients, as well as intratumoral heterogeneity, limits the efficacy of these drugs to specific patient subtypes, as well as contributes to relapse. Thus, there is a need for a more personalized approach toward drug development and diagnosis that takes into account the diversity of cancer patients, as well as the complex milieu of tumor cells within a single patient. Three-dimensional (3D) culture systems paired with patient-derived xenografts or patient-derived organoids may provide a more clinically relevant system to address issues presented by personalized or precision medical approaches. In this review, we cover the current methods available for applying 3D culture systems toward personalized cancer research and drug development, as well as key challenges that must be addressed in order to fully realize the potential of 3D patient-derived culture systems for cancer drug development. Greater implementation of 3D patient-derived culture systems in the cancer research field should accelerate the development of truly personalized medical therapies for cancer patients.

    Complementary and alternative medicines (CAMs), in particular herbal medicines, are commonly used by cancer patients in conjunction with chemotherapy treatment for their anticancer properties and supportive care. However, the effects of many of these herbs are not well-documented due to limited studies done on them. Severe herb-drug interactions (HDIs) have been recorded in some cases, and failure to recognize these harmful HDIs can lead to dire consequences in cancer patients. This study discusses clinically-relevant interactions between anticancer drugs (ACDs) and herbs classified into 7 categories: cancer treatment and prevention, immune-system-related, alopecia, nausea and vomiting, peripheral neuropathy and pain, inflammation, and fatigue. Some promising patents which contain these herbs and thus may manifest these interactions are also presented in this article. Pharmacokinetic interactions involved mainly induction or inhibition of the cytochrome P450 isozymes and p-glycoprotein, while pharmacodynamic interactions were related to increased risks of central nervous system-related effects, hepatotoxicity and bleeding, among others. Clinicians should be vigilant when treating cancer patients who take CAMs with concurrent chemotherapy since they face a high risk of HDIs. These HDIs can be minimized or avoided by selecting herb-drug pairs which are less likely to interact. Furthermore, close monitoring of pharmacological effects and plasma drug levels should be carried out to avoid toxicity and ensure adequate chemotherapeutic coverage in patients with cancer.

    Full Text Available Clostridium difficile is considered to be one of the most important causes of health care-associated infections worldwide. In order to understand more fully the adaptive response of the organism to stressful conditions, we examined transcriptional changes resulting from a clinically relevant heat stress (41 °C versus 37 °C in C. difficile strain 630 and identified 341 differentially expressed genes encompassing multiple cellular functional categories. While the transcriptome was relatively resilient to the applied heat stress, we noted upregulation of classical heat shock genes including the groEL and dnaK operons in addition to other stress-responsive genes. Interestingly, the flagellin gene (fliC was downregulated, yet genes encoding the cell-wall associated flagellar components were upregulated suggesting that while motility may be reduced, adherence--to mucus or epithelial cells--could be enhanced during infection. We also observed that a number of phage associated genes were downregulated, as were genes associated with the conjugative transposon Tn5397 including a group II intron, thus highlighting a potential decrease in retromobility during heat stress. These data suggest that maintenance of lysogeny and genome wide stabilisation of mobile elements could be a global response to heat stress in this pathogen.

    Purpose Evaluate the potential Drug–Drug Interactions (pDDI) found in prescription orders of adult Intensive Care Unit (ICU) of a Brazilian public health system hospital; quantify and qualify the pDDI regarding their severity and risks to the critical patient, using the database from Micromedex®. Methods Prospective study (January–December of 2011) collecting and evaluating 369 prescription orders (convenient sampling), one per patient. Results During the study 1844 pDDIs were identified and distributed in 405 pairs (medication A × medication B combination). There was an average of 5.00 ± 5.06 pDDIs per prescription order, the most prevalent being moderate and important interactions, present in 74% and 67% of prescription orders, respectively. In total, there were 9 contraindicated, 129 important and 204 moderate pDDIs. Among them 52 had as management recommendation to “avoid concomitant use” or “suspension of medication”, while 306 had as recommendation “continuous and adequate monitoring”. Conclusion The high number of pDDIs found in the study combined with the evaluation of the clinical relevancy of the most frequent pDDIs in the ICU shows that moderate and important interactions are highly incident. As the majority of them demand monitoring and adequate management, being aware of these interactions is major information for the safe and individualized risk management. PMID:27134536

    Although high biocompatibility promotes the use of titanium (Ti) alloy in spinal implants, this material shows high stiffness, which is an issue for removal by drilling. The recently developed, porous Ti foam implants, which have shown enhanced osteoformation, may overcome this flaw. Thus, this study aimed to compare the mechanical and thermal characteristics of Ti-foam (80 % porosity) and conventional Ti alloy (0 % porosity) implants drilled in clinically relevant conditions. Mechanical properties were analyzed by measuring axial and torque forces using a pressure sensor with a drill of 2.5-mm diameter at a rotation frequency of 20 Hz. Thermography was used to evaluate the heat generated by a diamond burr attached to a high-speed (80,000 rpm) drill. The torque and axial strengths of Ti foam (13.63 ± 1.43 and 82.60 ± 7.78 N, respectively) were significantly lower (P = 0.001) than those of Ti alloy (73.58 ± 13.60 and 850.72 ± 146.99 N, respectively). Furthermore, irrigation reduced the area of local heating for Ti foam to 56-82 % of that for Ti alloy, indicating lower thermal conductivity. These data suggest that the use of Ti foam implants may be advantageous in cases with a probability of implant drilling in the future.

    Full Text Available Extracellular membrane vesicles are fragments shed from plasma membranes off all cell types that are undergoing apoptosis or are being subjected to various types of stimulation or stress.  Even in the process of programmed cell death (apoptosis, cell fall apart of varying size vesicles. They expose phosphatidylserine (PS on the outer leaflet of their membrane, and bear surface membrane antigens reflecting their cellular origin. Extracellular membrane vesicles have been isolated from many types of biological fluids, including serum, cerebrospinal fluid, urine, saliva, tears and conditioned culture medium. Flow cytometry is one of the many different methodological approaches that have been used to analyze EMVs. The method attempts to characterize the EMVs cellular origin, size, population, number, and structure. EMVs are present and accumulate in blood products (erythrocytes, platelets as well as in fresh frozen plasma during storage. The aim of this review is to highlight the importance of extracellular vesicles as a cell-to-cell communication system and the role in the pathogenesis of different diseases. Special emphasis will be given to the implication of extracellular membrane vesicles in blood products and their clinical relevance. Although our understanding of the role of  EMVs in disease is far from comprehensive, they display promise as biomarkers for different diseases in the future and also as a marker of quality and safety in the quality control of blood products.

    2015-01-01

    The development of dysfunctional or exhausted T cells is characteristic of immune responses to chronic viral infections and cancer. Exhausted T cells are defined by reduced effector function, sustained upregulation of multiple inhibitory receptors, an altered transcriptional program and perturbations of normal memory development and homeostasis. This review focuses on (a) illustrating milestone discoveries that led to our present understanding of T cell exhaustion, (b) summarizing recent developments in the field, and (c) identifying new challenges for translational research. Exhausted T cells are now recognized as key therapeutic targets in human infections and cancer. Much of our knowledge of the clinically relevant process of exhaustion derives from studies in the mouse model of Lymphocytic choriomeningitis virus (LCMV) infection. Studies using this model have formed the foundation for our understanding of human T cell memory and exhaustion. We will use this example to discuss recent advances in our understanding of T cell exhaustion and illustrate the value of integrated mouse and human studies and will emphasize the benefits of bi-directional mouse-to-human and human-to-mouse research approaches.

    Genus Campylobacter has been recognized as a causative bacterial agent of animal and human diseases. Human Campylobacter infections have caused more concern. Campylobacters can be classified into two groups in terms of their original host: zoonotic and human oral species. The major zoonotic species are Campylobacter jejuni and Campylobacter coli, which mostly reside in the intestines of avian species and are transmitted to humans via consumption of contaminated poultry products, thus causing human gastroenteritis and other diseases as sequelae. The other campylobacters, human oral species, include C. concisus, C. showae, C. gracilis, C. ureolyticus, C. curvus, and C. rectus. These species are isolated from the oral cavity, natural colonization site, but have potential clinical relevance in the periodontal region to varying extent. Two species, C. jejuni and C. coli, are believed to be mainly associated with intestinal diseases, but recent studies suggested that oral Campylobacter species also play a significant role in intestinal diseases. This review offers an outline of the two Campylobacter groups (zoonotic and human oral), their virulence traits, and the associated illnesses including gastroenteritis.

    The beautiful report by Sachse in this issue of the journal represents the culmination of 2 decades of increasingly exciting work on the {open_quotes}debrisoquine oxidation polymorphism,{close_quotes} one of dozens of pharmacogenetic or ecogenetic polymorphisms that have been shown to have an important impact on innumerable clinical diseases. Pharmacogenetics is the study of the hereditary basis of the differences in responses to drugs. Ecogenetics is the broader field of interindividual differences in response to all environmental chemical and physical agents (e.g., heavy metals, insecticides, compounds formed during combustion, and UV radiation). It is now clear that each of us has his or her own {open_quotes}individual fingerprint{close_quotes} of unique alleles encoding the so-called drug-metabolizing enzymes (DMEs) and the receptors that regulate these enzymes. In this invited editorial, I first introduce the current thinking in the field of DME (and DME-receptor) research and how DMEs have evolved from animal-plant interactions. I then describe the debrisoquine oxidation polymorphism, as well as two other relevant DME polymorphisms; show the relationship between these polymorphisms and human disease; provide examples of synergistic effects caused by the combination of two DME polymorphisms; and discuss the ethical considerations of such research. Last, I speculate on why these allelic frequencies of the DME genes might exist in human populations in the first place. 35 refs.

  9. Clinical relevance of oxidative stress and sperm chromatin damage in male infertility: an evidence based analysis

    2007-10-01

    Full Text Available Oxidative stress (OS in the reproductive tract is now a real entity and concern due to the potential harmful effects of high levels of reactive oxygen species (ROS on sperm number, motility, quality, and function including damage to sperm nuclear DNA. Evaluation of OS related damage to non-functional sperm is highly relevant as intracytoplasmic sperm injection (ICSI technique, an effective therapy for severe male factor infertility, bypasses the majority of reproductive tract deficiencies. Despite the controversial findings in the existing literature, there is now enough evidence to show that sperm DNA damage is detrimental to reproductive outcomes. In addition, spermatozoa of infertile men are suggested to carry more DNA damage than do the spermatozoa from fertile men. Besides impairment of fertility such damage is likely to increase the transmission of genetic diseases during the assisted reproductive procedures. Standardization of protocols to assess reactive oxygen species and DNA damage is very important in introducing these tests in such clinical practice. Thus evaluation of seminal ROS levels and extent of sperm DNA damage especially in an infertile male may help develop new therapeutic strategies and improve success of assisted reproductive techniques (ART.

    Full Text Available Purpose. To investigate the reproducibility of aortic distensibility (D measurement using CT and assess its clinical relevance in patients with infrarenal abdominal aortic aneurysm (AAA. Methods. 54 patients with infrarenal abdominal aortic aneurysm were studied to determine their distensibility by using 64-MDCT. Aortic cross-sectional area changes were determined at two positions of the aorta, immediately below the lowest renal artery (level 1. and at the level of its maximal diameter (level 2. by semiautomatic segmentation. Measurement reproducibility was assessed using intraclass correlation coefficient (ICC and Bland-Altman analyses. Stepwise multiple regression analysis was performed to assess linear associations between aortic D and anthropometric and biochemical parameters. Results. A mean distensibility of Dlevel  1.=(1.05±0.22×10-5  Pa-1 and Dlevel  2.=(0.49±0.18×10-5  Pa-1 was found. ICC proved excellent consistency between readers over two locations: 0.92 for intraobserver and 0.89 for interobserver difference in level 1. and 0.85 and 0.79 in level 2. Multivariate analysis of all these variables showed sac distensibility to be independently related (R2=0.68 to BMI, diastolic blood pressure, and AAA diameter. Conclusions. Aortic distensibility measurement in patients with AAA demonstrated high inter- and intraobserver agreement and may be valuable when choosing the optimal dimensions graft for AAA before endovascular aneurysm repair.

    Intestinal transporters are crucial determinants in the oral absorption of many drugs. We therefore studied the mRNA expression (N = 33) and absolute protein content (N = 10) of clinically relevant transporters in healthy epithelium of the duodenum, the proximal and distal jejunum and ileum, and the ascending, transversal, descending, and sigmoidal colon of six organ donors (24-54 years). In the small intestine, the abundance of nearly all studied proteins ranged between 0.2 and 1.6 pmol/mg with the exception of those of OCT3 (intestinal segment. ABCB1, ABCG2, PEPT1, and ASBT were significantly more abundant in jejunum and ileum than in colon. In contrast to this, the level of expression of ABCC2, ABCC3, and OCT3 was found to be highest in colon. Site-dependent differences in the levels of gene and protein expression were observed for ABCB1 and ASBT. Significant correlations between mRNA and protein levels have been found for ABCG2, ASBT, OCT3, and PEPT1 in the small intestine. Our data provide further physiological pieces of the puzzle required to predict intestinal drug absorption in humans.

    Objective:To determine the accuracy of TB diagnosis of TB in Zambia in the era of increasing HIV prevalence. Methods: Sputum of the clinically diagnosed TB cases was additionally subjected to liquid culture and molecular identification. This study distinguished between TB cases confirmed by positive Mycobacterium tuberculosis (M. tuberculosis) cultures and mycobacterial disease caused by non-tuberculous mycobacteria (NTM). Results: Only 49%of the 173 presumptively diagnosed TB cases was M. tuberculosis cultured, while in 13%(22) cases, a combination of M. tuberculosis and NTM was found. In 18%of the patients only NTM were cultured. In 28%, no mycobacteria was cultivable. HIV positive status was correlated with the isolation of NTM (P<0.05). Conclusions:The diagnosis of tuberculosis based on symptoms, sputum smear and/or chest X-ray leads to significant numbers of false-positive TB cases in Zambia, most likely due to the increased prevalence of HIV. The role of NTM in tuberculosis-like disease also seems relevant to the false diagnosis of TB in Zambia.

    Microbiological drinking water safety is traditionally monitored mainly by bacterial parameters that indicate faecal contamination. These parameters correlate with gastro-intestinal illness, despite the fact that viral agents, resulting from faecal contamination, are usually the cause. This leaves behind microbes that can cause illness other than gastro-intestinal and several emerging pathogens, disregarding non-endemic microbial contaminants and those with recent pathogenic activity reported. This white paper focuses on one group of contaminants known to cause allergies, opportunistic infections and intoxications: Fungi. It presents a review on their occurrence, ecology and physiology. Additionally, factors contributing to their presence in water distribution systems, as well as their effect on water quality are discussed. Presence of opportunistic and pathogenic fungi in drinking water can pose a health risk to consumers due to daily contact with water, via several exposure points, such as drinking and showering. The clinical relevance and influence on human health of the most common fungal contaminants in drinking water is discussed. Our goal with this paper is to place fungal contaminants on the roadmap of evidence based and emerging threats for drinking water quality safety regulations.

    Occult hepatitis B virus (HBV) infection is a world-wide entity, following the geographical distribution of detectable hepatitis B. This entity is defined as the persistence of viral genomes in the liver tissue and in some instances also in the serum, associated to negative HBV surface antigen serology. The molecular basis of the occult infection is related to the life cycle of HBV, which produces a covalently closed circular DNA that persists in the cell nuclei as an episome, and serves as a template for gene transcription. The mechanism responsible for the HBsAg negative status in occult HBV carriers is a strong suppression of viral replication, probably due to the host's immune response, co-infection with other infectious agents and epigenetic factors. There is emerging evidence of the potential clinical relevance of occult HBV infection, since this could be involved in occult HBV transmission through orthotopic liver transplant and blood transfusion, reactivation of HBV infection during immunosuppression, impairing chronic liver disease outcome and acting as a risk factor for hepatocellular carcinoma. Therefore it is important to bear in mind this entity in cryptogenetic liver diseases, hepatitis C virus/HIV infected patients and immunosupressed individuals.It is also necessary to increase our knowledge in this fascinating field to define better strategies to diagnose and treat this infection.

    Despite the satisfactory short-term implant survivorship of metal-on-metal hip resurfacing arthroplasty, periprosthetic soft-tissue masses such as pseudotumours are being increasingly reported. Cytotoxic effects of cobalt or chromium have been suggested to play a role in its aetiology. The aim of this study was to investigate the effects of clinically relevant metal nanoparticles and ions on the viability of macrophages in vitro. A RAW 264.7 murine macrophage cell line was cultured in the presence of either: (1) cobalt, chromium and titanium nanoparticles sized 30-35 nm; or (2) cobalt sulphate and chromium chloride. Two methods were used to quantify cell viability: Alamar Blue assay and Live/Dead assay. The cytotoxicity was observed only with cobalt. Cobalt nanoparticles and ions demonstrated dose-dependent cytotoxic effects on macrophages in vitro: the cytotoxic concentrations of nanoparticles and ions were 1 x 10{sup 12} particles ml{sup -1} and 1000 {mu}M, respectively. The high concentration of cobalt nanoparticles required for cytotoxicity of macrophages in vitro suggests that increased production of cobalt nanoparticles in vivo, due to excessive MoM implant wear, may lead to local adverse biological effects. Therefore, cytotoxicity of high concentrations of metal nanoparticles phagocytosed by macrophages located in the periprosthetic tissues may be an important factor in pathogenesis of pseudotumours.

    We have designed a clinically relevant model of perinatal asphyxia providing intrapartum hypoxia in rats. On gestation day 22 SD rats were anesthetized and the uterine horns were exteriorized and placed in a water bath at 37°C for up to 20min. After this, pups were delivered from the uterus and manually stimulated to initiate breathing in an incubator at 37°C for 1 h in air. Brains were harvested and stained with cresyl violet, caspase-3, and TUNEL to detect morphological and apoptotic changes on postnatal days (PND) 1, 3, and 7. Separate cohorts were maintained until PND 50 and tested for learning and memory using Morris water maze (WM). Survival rate was decreased with longer hypoxic time, and 100% mortality was noted when hypoxia time was beyond 18min. Apoptosis was increased with the duration of hypoxia with neuronal loss and cell shrinkage in the CA1 of hippocampus. The time taken for the juveniles to locate the hidden platform during WM was increased in animals subjected to hypoxia. These data demonstrate that perinatal ischemic injury leads to neuronal death in the hippocampus and long-lasting cognitive dysfunction. This model mimics hypoxic ischemic encephalopathy in humans and may be appropriate for investigating therapeutic interventions. Copyright © 2011 Elsevier B.V. All rights reserved.

    2012-01-01

    Spinal muscular atrophy (SMA), a motoneuron disease caused by a deficiency of the survival of motor neuron (SMN) protein, is characterized by motoneuron loss and muscle weakness. It remains unclear whether widespread loss of neuromuscular junctions (NMJs) is involved in SMA pathogenesis. We undertook a systematic examination of NMJ innervation patterns in >20 muscles in the SMNΔ7 SMA mouse model. We found that severe denervation (<50% fully innervated endplates) occurs selectively in many vulnerable axial muscles and several appendicular muscles at the disease end stage. Since these vulnerable muscles were located throughout the body and were comprised of varying muscle fiber types, it is unlikely that muscle location or fiber type determines susceptibility to denervation. Furthermore, we found a similar extent of neurofilament accumulation at NMJs in both vulnerable and resistant muscles before the onset of denervation, suggesting that neurofilament accumulation does not predict subsequent NMJ denervation. Since vulnerable muscles were initially innervated, but later denervated, loss of innervation in SMA may be attributed to defects in synapse maintenance. Finally, we found that denervation was amendable by trichostatin A (TSA) treatment, which increased innervation in clinically relevant muscles in TSA-treated SMNΔ7 mice. Our findings suggest that neuromuscular denervation in vulnerable muscles is a widespread pathology in SMA, and can serve as a preparation for elucidating the biological basis of synapse loss, and for evaluating therapeutic efficacy.

[/b]The Medline database was searched using the key words ‘chronic pelvic pain’ and ‘pelvic congestion syndrome’, published in English during the past 15 years. The condition markedly deteriorates the quality of life of the affected. Its aetiology has not been fully described and elucidated, although organic, functional and psychosomatic factors are implicated. Pain associated with parametrial varices was defined as pelvis congestion syndrome (PCS. Since the aetiology of CPP is complex, multi-directional diagnostic procedures are required. [b]Results. [/b]The main diagnostic methods employed are imaging examinations (ultrasound, computer tomography, magnetic resonance. Advances in interventional radiology considerably contributed to the CPP treatment. Currently, embolization of parametrial vessels is one of the most effective methods to relieve pain associated with pelvic congestion syndrome. [b]Conclusions. [/b]Due to the complex aetiology of chronic pelvic pain, the most beneficial effects are obtained when the therapy is based on cooperation of the gynaecologist, physiotherapist, psychologist and interventional radiologist.

    2014-01-01

    Clinicians and clinical researchers often seek information in electronic health records (EHRs) that are relevant to some concept of interest, such as a disease or finding. The heterogeneous nature of EHRs can complicate retrieval, risking incomplete results. We frame this problem as the presence of two gaps: 1) a gap between clinical concepts and their representations in EHR data and 2) a gap between data representations and their locations within EHR data structures. We bridge these gaps with a knowledge structure that comprises relationships among clinical concepts (including concepts of interest and concepts that may be instantiated in EHR data) and relationships between clinical concepts and the database structures. We make use of available knowledge resources to develop a reproducible, scalable process for creating a knowledge base that can support automated query expansion from a clinical concept to all relevant EHR data.

    Directory of Open Access Journals (Sweden)

    Weijing Zhang

    Full Text Available The β1,3-N-acetylglucosaminyltransferase-3 gene (B3GNT3 encodes a member of the B3GNT family that functions as the backbone structure of dimeric sialyl-Lewis A and is involved in L-selectin ligand biosynthesis, lymphocyte homing and lymphocyte trafficking. B3GNT3 has been implicated as an important element in the development of certain cancers. However, the characteristics of B3GNT3 in the development and progression of cancer remain largely unknown. Thus, our study aimed to investigate the expression pattern and the prognostic value of B3GNT3 in patients with early-stage cervical cancer.The mRNA and protein levels of B3GNT3 expression were examined in eight cervical cancer cell lines and ten paired cervical cancer tumors, using real-time PCR and western blotting, respectively. Immunohistochemistry (IHC was used to analyze B3GNT3 protein expression in paraffin-embedded tissues from 196 early-stage cervical cancer patients. Statistical analyses were applied to evaluate the association between B3GNT3 expression scores and clinical parameters, as well as patient survival.B3GNT3 expression was significantly upregulated in cervical cancer cell lines and lesions compared with normal cells and adjacent noncancerous cervical tissues. In the 196 cases of tested early-stage cervical cancer samples, the B3GNT3 protein level was positively correlated with high risk TYPES of human papillomavirus (HPV infection (P = 0.026, FIGO stage (P < 0.001, tumor size (P = 0.025, tumor recurrence (P = 0.004, vital status (P < 0.001, concurrent chemotherapy and radiotherapy (P = 0.016, lymphovascular space involvement (P = 0.003 and most importantly, lymph node metastasis (P = 0.003. Patients with high B3GNT3 expression had a shorter overall survival (OS and disease-free survival (DFS compared with those with low expression of this protein. Multivariate analysis suggested that B3GNT3 expression is an independent prognostic indicator for cervical cancer patients.Our study

    To evaluate the clinical relevance of antiphospholipid antibodies (aPL) in systemic sclerosis (SSc). A systematic search of EMBASE and PubMed databases from January 1983 to July 2016 was carried out according to PRISMA guidelines whereas Peto׳s odds ratio (OR) for rare events was used for the meta-analysis. The pooled prevalence of participants positive for IgG and IgM anticardiolipin (aCL) antibodies was higher in SSc than controls (12.8% vs 1.6% and 7.8% vs 0.6%; p < 0.0001 for both) as was that of IgG and IgM anti-beta-2-glycoprotein-I antibodies (aβ2GPI) (6.1% vs 0.58%, p < 0.0001; 3.5% vs 0.3%, p = 0.001). The pooled prevalence of pulmonary arterial hypertension (PAH) was more common in SSc positive than negative patients for aCL (IgG/IgM combined) (26.5% vs 10.9%, p < 0.0001) whereas the pooled prevalence of renal disease (RD) was more common in IgG aCL positive than negative patients (36.3% vs 10.9%, p = 0.02). The pooled prevalence of thrombosis was higher in IgG aCL, IgM aCL, and IgM aβ2GPI positive than negative SSc patients (12.6% vs 1.4%, p < 0.0001), (15.1% vs 2.7%, p = 0.002) and (15% vs 0.78%, p = 0.009), respectively. The pooled prevalence of digital infarction/ischemia (DI) was higher in IgG aCL and IgM positive than negative SSc (52.8% vs 39.8%, p = 0.002) and (68.1% vs 29%, p = 0.07). A strong relationship exists between aCL and aβ2GPI of IgG/IgM isotype and SSc; patients positive for these antibodies are more likely to suffer from PAH, RD, thrombosis, and DI. However, data expressed as frequency of aPL positive patients rather than average antibody titers preclude further insight into the relevance of these assumptions. Copyright © 2017 Elsevier Inc.

In this study, host tissue response and biomechanical properties of mesh fabricated from co-electrospun poly(L-lactide-co-caprolactone (PLCL and fibrinogen (Fg were compared with those of polypropylene mesh (PPM in a canine abdominal defect model. Macroscopic, microscopic, histological, and biomechanical evaluations were performed over a 24-week period. The results showed that PLCL/Fg mesh had similar host tissue responses but better initial vascularization and graft site tissue organization than PPM. The efficacy of the PLCL/Fg mesh was further examined in human pelvic floor reconstruction. Operation time, intraoperative blood loss, and pelvic organ prolapse quantification during 6-month follow-up were compared for patients receiving PLCL/Fg mesh versus PPM. According to the pelvic organ prolapse quantification scores, the anterior vaginal wall 3 cm proximal to the hymen point (Aa point, most distal edge of the cervix or vaginal cuff scar point (C point, and posterior fornix point (D point showed significant improvement (P<0.01 at 1, 3, and 6 months for both groups compared with preoperatively. At 6 months, improvements at the Aa point in the PLCL/Fg group were significantly more (P<0.005 than the PPM group, indicating that, while both materials improve the patient symptoms, PLCL/Fg mesh resulted in more obvious

    Full Text Available Abstract Background Chondrosarcoma responds poorly to adjuvant therapy and new, clinically relevant animal models are required to test targeted therapy. Methods Two human chondrosarcoma cell lines, JJ012 and FS090, were evaluated for proliferation, colony formation, invasion, angiogenesis and osteoclastogenesis. Cell lines were also investigated for VEGF, MMP-2, MMP-9, and RECK expression. JJ012 and FS090 were injected separately into the mouse tibia intramedullary canal or tibial periosteum. Animal limbs were measured, and x-rayed for evidence of tumour take and progression. Tibias and lungs were harvested to determine the presence of tumour and lung metastases. Results JJ012 demonstrated significantly higher proliferative capacity, invasion, and colony formation in collagen I gel. JJ012 conditioned medium stimulated endothelial tube formation and osteoclastogenesis with a greater potency than FS090 conditioned medium, perhaps related to the effects of VEGF and MMP-9. In vivo, tumours formed in intratibial and periosteal groups injected with JJ012, however no mice injected with FS090 developed tumours. JJ012 periosteal tumours grew to 3 times the non-injected limb size by 7 weeks, whereas intratibial injected limbs required 10 weeks to achieve a similar tumour size. Sectioned tumour tissue demonstrated features of grade III chondrosarcoma. All JJ012 periosteal tumours (5/5 resulted in lung micro-metastases, while only 2/4 JJ012 intratibial tumours demonstrated metastases. Conclusions The established JJ012 models replicate the site, morphology, and many behavioural characteristics of human chondrosarcoma. Local tumour invasion of bone and spontaneous lung metastasis offer valuable assessment tools to test the potential of novel agents for future chondrosarcoma therapy.

  19. Anatomical masking of pressure footprints based on the Oxford Foot Model: validation and clinical relevance.

    2017-03-01

    Plantar pressure analysis is widely used in the assessment of foot function. In order to assess regional loading, a mask is applied to the footprint to sub-divide it into regions of interest (ROIs). The most common masking method is based on geometric features of the footprint (GM). Footprint masking based on anatomical landmarks of the foot has been implemented more recently, and involves the integration of a 3D motion capture system, plantar pressure measurement device, and a multi-segment foot model. However, thorough validation of anatomical masking (AM) using pathological footprints has not yet been presented. In the present study, an AM method based on the Oxford Foot Model (OFM) was compared to an equivalent GM. Pressure footprints from 20 young healthy subjects (HG) and 20 patients with clubfoot (CF) were anatomically divided into 5 ROIs using a subset of the OFM markers. The same foot regions were also identified by using a standard GM method. Comparisons of intra-subject coefficient of variation (CV) showed that the OFM-based AM was at least as reliable as the GM for all investigated pressure parameters in all foot regions. Clinical relevance of AM was investigated by comparing footprints from HG and CF groups. Contact time, maximum force, force-time integral and contact area proved to be sensitive parameters that were able to distinguish HG and CF groups, using both AM and GM methods However, the AM method revealed statistically significant differences between groups in 75% of measured variables, compared to 62% using a standard GM method, indicating that the AM method is more sensitive for revealing differences between groups.

  20. Human Y chromosome microdeletion analysis by PCR multiplex protocols identifying only clinically relevant AZF microdeletions.

    Science.gov (United States)

    Vogt, Peter H; Bender, Ulrike

    2013-01-01

    PCR multiplex assays are the method of choice for quickly revealing genomic microdeletions in the large repetitive genomic sequence blocks on the long arm of the human Y chromosome. They harbor the Azoospermia Factor (AZF) genes, which cause male infertility when functionally disrupted. These protein encoding Y genes are expressed exclusively or predominantly during male germ cell development, i.e., at different phases of human spermatogenesis. They are located in three distinct genomic sequence regions designated AZFa, AZFb, and AZFc, respectively. Complete deletion of an AZF region, also called "classical" AZF microdeletion, is always associated with male infertility and a distinct testicular pathology. Partial AZF deletions including single AZF Y genes can cause the same testicular pathology as the corresponding complete deletion (e.g., DDX3Y gene deletions in AZFa), or might not be associated with male infertility at all (e.g., some BPY2, CDY1, DAZ gene deletions in AZFc). We therefore propose that a PCR multiplex assay aimed to reduce only those AZF microdeletions causing a specific testicular pathology-thus relevant for clinical applications. It only includes Sequence Tagged Site (STS) deletion markers inside the exon structures of the Y genes known to be expressed in male germ cells and located in the three AZF regions. They were integrated in a robust standard protocol for four PCR multiplex mixtures which also include the basic principles of quality control according to the strict guidelines of the European Molecular Genetics Quality Network (EMQN: http://www.emqn.org). In case all Y genes of one AZF region are deleted the molecular extension of this AZF microdeletion is diagnosed to be yes or no comparable to that of the "classical" AZF microdeletion by an additional PCR multiplex assay analyzing the putative AZF breakpoint borderlines.

  1. Molecular Mechanisms of Glutamine Synthetase Mutations that Lead to Clinically Relevant Pathologies.

    Full Text Available Glutamine synthetase (GS catalyzes ATP-dependent ligation of ammonia and glutamate to glutamine. Two mutations of human GS (R324C and R341C were connected to congenital glutamine deficiency with severe brain malformations resulting in neonatal death. Another GS mutation (R324S was identified in a neurologically compromised patient. However, the molecular mechanisms underlying the impairment of GS activity by these mutations have remained elusive. Molecular dynamics simulations, free energy calculations, and rigidity analyses suggest that all three mutations influence the first step of GS catalytic cycle. The R324S and R324C mutations deteriorate GS catalytic activity due to loss of direct interactions with ATP. As to R324S, indirect, water-mediated interactions reduce this effect, which may explain the suggested higher GS residual activity. The R341C mutation weakens ATP binding by destabilizing the interacting residue R340 in the apo state of GS. Additionally, the mutation is predicted to result in a significant destabilization of helix H8, which should negatively affect glutamate binding. This prediction was tested in HEK293 cells overexpressing GS by dot-blot analysis: Structural stability of H8 was impaired through mutation of amino acids interacting with R341, as indicated by a loss of masking of an epitope in the glutamate binding pocket for a monoclonal anti-GS antibody by L-methionine-S-sulfoximine; in contrast, cells transfected with wild type GS showed the masking. Our analyses reveal complex molecular effects underlying impaired GS catalytic activity in three clinically relevant mutants. Our findings could stimulate the development of ATP binding-enhancing molecules by which the R324S mutant can be repaired extrinsically.

    This study evaluated interaction potential between sugammadex and aspirin on platelet aggregation. This was a randomized, double-blind, placebo-controlled, four-period crossover study in 26 healthy adult males. Treatments were i.v. placebo, i.v. sugammadex 4 mg/kg, and i.v. placebo/sugammadex with oncedaily oral aspirin 75 mg. Primary objective was to assess interaction between sugammadex and aspirin on platelet aggregation using collagen-induced whole-blood aggregometry. Effects on activated partial thromboplastin time (APTT) and cutaneous bleeding time were also evaluated. Platelet aggregation and APTT were evaluated by geometric mean ratios, using area-under-effect curves 3 - 30 minutes after sugammadex/placebo dosing. Bleeding time ratio was evaluated at 5 minutes post-dosing. Non-inferiority margins were pre-specified via literature review. Type I error was controlled using a hierarchical strategy. Ratio for platelet aggregation for aspirin with sugammadex vs. aspirin alone was 1.01, with lower limit of two-sided 90% CI of 0.91(above non-inferiority margin of 0.75). Ratio for statistical interaction between sugammadex and aspirin on APTT was 1.01, with upper 90% CI of 1.04 (below non-inferiority margin of 1.50), and for sugammadex vs. placebo alone was 1.06, with an upper 90% CI of 1.07 (below non-inferiority margin of 1.50). Ratio for bleeding time for aspirin with sugammadex vs. aspirin plus placebo was 1.20, with upper 90% CI of 1.45 (below non-inferiority margin of 1.50). Sugammadex was generally well tolerated. There was no clinically relevant reduction in platelet aggregation with addition of sugammadex 4 mg/kg to aspirin. Pre-determined non-inferiority margins were not exceeded for bleeding time and APTT.

    We conducted an evaluation of the intercamera (i.e., between cameras) variability in clinically relevant performance characteristics for Symbia gamma cameras (Siemens Medical Solutions, Malvern, PA) based on measurements made using nine separate systems. The significance of the observed intercamera variability was determined by comparing it to the intracamera (i.e., within a single camera) variability. Measurements of performance characteristics were based on the standards of the National Electrical Manufacturers Association and reports 6, 9, 22, and 52 from the American Association of Physicists in Medicine. All measurements were performed using 99mTc (except 57Co used for extrinsic resolution) and low-energy, high-resolution collimation. Of the nine cameras, four have crystals 3/8 in. thick and five have crystals 5/8 in. thick. We evaluated intrinsic energy resolution, intrinsic and extrinsic spatial resolution, intrinsic integral and differential flood uniformity over the useful field-of-view, count rate at 20% count loss, planar sensitivity, single-photon emission computed tomography (SPECT) resolution, and SPECT integral uniformity. The intracamera variability was estimated by repeated measurements of the performance characteristics on a single system. The significance of the observed intercamera variability was evaluated using the two-tailed F distribution. The planar sensitivity of the gamma cameras tested was found be variable at the 99.8% confidence level for both the 3/8-in. and 5/8-in. crystal systems. The integral uniformity and energy resolution were found to be variable only for the 5/8-in. crystal systems at the 98% and 90% confidence level, respectively. All other performance characteristics tested exhibited no significant variability between camera systems. The measured variability reported here could perhaps be used to define nominal performance values of Symbia gamma cameras for planar and SPECT imaging.

    Full Text Available Abstract Background The biological relevance of nuclear ErbB-2/HER2 (NuclErbB-2 presence in breast tumors remains unexplored. In this study we assessed the clinical significance of ErbB-2 nuclear localization in primary invasive breast cancer. The reporting recommendations for tumor marker prognostic studies (REMARK guidelines were used as reference. Methods Tissue microarrays from a cohort of 273 primary invasive breast carcinomas from women living in Chile, a Latin American country, were examined for membrane (MembErbB-2 and NuclErbB-2 expression by an immunofluorescence (IF protocol we developed. ErbB-2 expression was also evaluated by immunohistochemistry (IHC with a series of antibodies. Correlation between NuclErbB-2 and MembErbB-2, and between NuclErbB-2 and clinicopathological characteristics of tumors was studied. The prognostic value of NuclErbB-2 in overall survival (OS was evaluated using Kaplan-Meier method, and Cox model was used to explore NuclErbB-2 as independent prognostic factor for OS. Results The IF protocol we developed showed significantly higher sensitivity for detection of NuclErbB-2 than IHC procedures, while its specificity and sensitivity to detect MembErbB-2 were comparable to those of IHC procedures. We found 33.6% NuclErbB-2 positivity, 14.2% MembErbB-2 overexpression by IF, and 13.0% MembErbB-2 prevalence by IHC in our cohort. We identified NuclErbB-2 positivity as a significant independent predictor of worse OS in patients with MembErbB-2 overexpression. NuclErbB-2 was also a biomarker of lower OS in tumors that overexpress MembErbB-2 and lack steroid hormone receptors. Conclusions We revealed a novel role for NuclErbB-2 as an independent prognostic factor of poor clinical outcome in MembErbB-2-positive breast tumors. Our work indicates that patients presenting NuclErbB-2 may need new therapeutic strategies involving specific blockage of ErbB-2 nuclear migration.

    2015-04-01

    Obesity is a growing public health concern now reaching epidemic status worldwide for children and adults due to multiple problems impacting on energy intake and expenditure with influences on human reproduction and infertility. A positive family history and genetic factors are known to play a role in obesity by influencing eating behavior, weight and level of physical activity and also contributing to human reproduction and infertility. Recent advances in genetic technology have led to discoveries of new susceptibility genes for obesity and causation of infertility. The goal of our study was to provide an update of clinically relevant candidate and known genes for obesity and infertility using high resolution chromosome ideograms with gene symbols and tabular form. We used computer-based internet websites including PubMed to search for combinations of key words such as obesity, body mass index, infertility, reproduction, azoospermia, endometriosis, diminished ovarian reserve, estrogen along with genetics, gene mutations or variants to identify evidence for development of a master list of recognized obesity genes in humans and those involved with infertility and reproduction. Gene symbols for known and candidate genes for obesity were plotted on high resolution chromosome ideograms at the 850 band level. Both infertility and obesity genes were listed separately in alphabetical order in tabular form and those highlighted when involved with both conditions. By searching the medical literature and computer generated websites for key words, we found documented evidence for 370 genes playing a role in obesity and 153 genes for human reproduction or infertility. The obesity genes primarily affected common pathways in lipid metabolism, deposition or transport, eating behavior and food selection, physical activity or energy expenditure. Twenty-one of the obesity genes were also associated with human infertility and reproduction. Gene symbols were plotted on high resolution

    Full Text Available BACKGROUND: Current blood based diagnostic assays to detect heart failure (HF have large intra-individual and inter-individual variations which have made it difficult to determine whether the changes in the analyte levels reflect an actual change in disease activity. Human saliva mirrors the body's health and well being and ∼20% of proteins that are present in blood are also found in saliva. Saliva has numerous advantages over blood as a diagnostic fluid which allows for a non-invasive, simple, and safe sample collection. The aim of our study was to develop an immunoassay to detect NT-proBNP in saliva and to determine if there is a correlation with blood levels. METHODS: Saliva samples were collected from healthy volunteers (n = 40 who had no underlying heart conditions and HF patients (n = 45 at rest. Samples were stored at -80°C until analysis. A customised homogeneous sandwich AlphaLISA((R immunoassay was used to quantify NT-proBNP levels in saliva. RESULTS: Our NT-proBNP immunoassay was validated against a commercial Roche assay on plasma samples collected from HF patients (n = 37 and the correlation was r(2 = 0.78 (p<0.01, y = 1.705× +1910.8. The median salivary NT-proBNP levels in the healthy and HF participants were <16 pg/mL and 76.8 pg/mL, respectively. The salivary NT-proBNP immunoassay showed a clinical sensitivity of 82.2% and specificity of 100%, positive predictive value of 100% and negative predictive value of 83.3%, with an overall diagnostic accuracy of 90.6%. CONCLUSION: We have firstly demonstrated that NT-proBNP can be detected in saliva and that the levels were higher in heart failure patients compared with healthy control subjects. Further studies will be needed to demonstrate the clinical relevance of salivary NT-proBNP in unselected, previously undiagnosed populations.

  11. Current Concepts of Pelvic Congestion and Chronic Pelvic Pain

    Science.gov (United States)

    2001-01-01

    Chronic pelvic pain in women is a common and disabling illness caused by numerous organic pathologies usually accompanied by varying psychological dysfunctions. Many patients may receive misdiagnosis, misdirected therapies, or do not seek help at all. Pelvic congestion may be responsible for pain in patients without more common diseases, such as endometriosis and pelvic adhesions, among others. Our view of this condition is evolving. In the United States, this medical condition remains controversial. More recent research from the United Kingdom has caused a fresh look at the diagnosis and treatment of chronic pelvic pain produced by pelvic congestion. Potentially, many patients may benefit from a reconsideration of this approach. PMID:11394421

    2016-05-01

    Full Text Available Lymphangioleiomyomatosis (LAM, a rare multisystem disease affecting mainly young women, is characterized by an abnormal proliferation of smooth muscle-like cells in the lungs. We report a case of endometriosis with chronic pelvic pain due to pelvic LAM. A 41-year-old gravida 1, para 1 woman had been experiencing intermittent left pelvic pain for several years. She also complained of dyspnea on effort 2 years previously, and was diagnosed with pulmonary LAM. Abdominal magnetic resonance imaging showed a right ovarian endometriotic cyst and a left pelvic mass. She was referred to our hospital for the treatment of pelvic pain; she underwent laparoscopic cystectomy of the right ovarian endometriotic cyst. Her left pelvic cyst was found in the retroperitoneal space, and biopsy confirmed the diagnosis of LAM. Therefore, we suggest that LAM localized in the pelvis should be considered when a patient with pulmonary LAM presents with pelvic pain or abdominal distention.

    Clinically relevant extended-spectrum beta-lactamase (ESBL)-producing multi-resistant Escherichia coli have been on the rise for years. Initially restricted to mostly a clinical context, recent findings prove their prevalence in extraclinical settings independent of the original occurrence of antimicrobial resistance in the environment. To get further insights into the complex ecology of potentially clinically relevant ESBL-producing E. coli, 24 isolates from wild birds in Berlin, Germany, and 40 ESBL-producing human clinical E. coli isolates were comparatively analyzed. Isolates of ST410 occurred in both sample groups (six). In addition, three ESBL-producing E. coli isolates of ST410 from environmental dog feces and one clinical dog isolate were included. All 10 isolates were clonally analyzed showing almost identical macrorestriction patterns. They were chosen for whole-genome sequencing revealing that the whole-genome content of these 10 E. coli isolates showed a very high genetic similarity, differing by low numbers of single nucleotide polymorphisms only. This study gives initial evidence for a recent interspecies transmission of a new successful clone of ST410 E. coli between wildlife, humans, companion animals and the environment. The results underline the zoonotic potential of clinically relevant multi-resistant bacteria found in the environment as well as the mandatory nature of the 'One Health' approach.

    Laparoendoscopic single site (LESS) has recently gained momentum as feasible techniques for minimal access surgery. Our aim is to describe the current status of laparoendoscopic single site (LESS) in pelvic surgery. A comprehensive revision of the literature in LESS pelvic surgery was performed. References for this manuscript were obtained by performing a review of the available literature in PubMed from 01-01-01 to 30-11-11. References outside the search period were obtained selected manuscript΄s bibliography. Search terms included: pelvic anatomy, less in gynecology, single port colectomy, urological less, single port, single site, NOTES, LESS and single incision. 314 manuscripts were initially identified. Out of these, 46 manuscripts were selected based in their pelvic anatomy or surgical content; including experimental experience, clinical series and literature reviews. LESS drastically limit the surgeon's ability to perform in the operative field and the latter becomes hardened by the lack of space in anatomical location like the pelvis. Potential advantages of LESS are gained with the understanding that the surgical procedure is more technically challenging. Pelvic surgical procedures related to colorectal surgery, gynecology and urology have been performed with LESS technique and information available is mostly represented by case reports and short case series. Comparative series remain few. LESS pelvic surgery remain in its very beginning and due to the very specific anatomical conditions further development of LESS surgery in the mentioned area can be clearly be facilitated by using robotic technology. Standardization ad reproducibility of techniques are mandatory to further develop LESS in the surgical arena..

    Laboratory receiver operating characteristic (ROC) studies, that are often used to evaluate medical imaging systems, differ from ‘live’ clinical interpretations in several respects which could compromise their clinical relevance. The aim was to develop methodology for quantifying the clinical relevance of a laboratory ROC study. A simulator was developed to generate ROC ratings data and binary clinical interpretations classified as correct or incorrect for a common set of images interpreted under clinical and laboratory conditions. The area under the trapezoidal ROC curve (AUC) was used as the laboratory figure-of-merit and the fraction of correct clinical decisions as the clinical figure-of-merit. Conventional agreement measures (Pearson, Spearman, Kendall and kappa) between the bootstrap-induced fluctuations of the two figures of merit were estimated. A jackknife pseudovalue transformation applied to the figures of merit was also investigated as a way to capture agreement existing at the individual image level that could be lost at the figure-of-merit level. It is shown that the pseudovalues define a relevance-ROC curve. The area under this curve (rAUC) measures the ability of the laboratory figure-of-merit-based pseudovalues to correctly classify incorrect versus correct clinical interpretations. Therefore, rAUC is a measure of the clinical relevance of an ROC study. The conventional measures and rAUC were compared under varying simulator conditions. It was found that design details of the ROC study, namely the number of bins, the difficulty level of the images, the ratio of disease-present to disease-absent images and the unavoidable difference between laboratory and clinical performance levels, can lead to serious underestimation of the agreement as indicated by conventional agreement measures, even for perfectly correlated data, while rAUC showed high agreement and was relatively immune to these details. At the same time rAUC was sensitive to factors such

    The multisystem nature of female chronic pelvic pain (CPP) makes this condition a challenge for physical therapists and other health care providers to manage. This article uses a case scenario to illustrate commonly reported somatic, visceral, and neurologic symptoms and their associated health and participation impact in a female with CPP. Differential diagnosis of pain generators requires an in-depth understanding of possible anatomic and physiologic contributors to this disorder. This article provides a detailed discussion of the relevant clinical anatomy with specific attention to complex interrelationships between anatomic structures potentially leading to the patient's pain. In addition, it describes the physical therapy management specific to this case, including examination, differential diagnosis, and progression of interventions.

    Full Text Available Abstract Background The major metabolic complications of obesity and type 2 diabetes may be prevented and managed with dietary modification. The use of sweeteners that provide little or no calories may help to achieve this objective. Methods We did a systematic review and network meta-analysis of the comparative effectiveness of sweetener additives using Bayesian techniques. MEDLINE, EMBASE, CENTRAL and CAB Global were searched to January 2011. Randomized trials comparing sweeteners in obese, diabetic, and healthy populations were selected. Outcomes of interest included weight change, energy intake, lipids, glycated hemoglobin, markers of insulin resistance and glycemic response. Evidence-based items potentially indicating risk of bias were assessed. Results Of 3,666 citations, we identified 53 eligible randomized controlled trials with 1,126 participants. In diabetic participants, fructose reduced 2-hour blood glucose concentrations by 4.81 mmol/L (95% CI 3.29, 6.34 compared to glucose. Two-hour blood glucose concentration data comparing hypocaloric sweeteners to sucrose or high fructose corn syrup were inconclusive. Based on two ≤10-week trials, we found that non-caloric sweeteners reduced energy intake compared to the sucrose groups by approximately 250-500 kcal/day (95% CI 153, 806. One trial found that participants in the non-caloric sweetener group had a decrease in body mass index compared to an increase in body mass index in the sucrose group (-0.40 vs 0.50 kg/m2, and -1.00 vs 1.60 kg/m2, respectively. No randomized controlled trials showed that high fructose corn syrup or fructose increased levels of cholesterol relative to other sweeteners. Conclusions Considering the public health importance of obesity and its consequences; the clearly relevant role of diet in the pathogenesis and maintenance of obesity; and the billions of dollars spent on non-caloric sweeteners, little high-quality clinical research has been done.

    Grey matter atrophy is common in multiple sclerosis. However, in contrast with other neurodegenerative diseases, it is unclear whether grey matter atrophy in multiple sclerosis is a diffuse 'global' process or develops, instead, according to distinct anatomical patterns. Using source-based morphometry we searched for anatomical patterns of co-varying cortical thickness and assessed their relationships with white matter pathology, physical disability and cognitive functioning. Magnetic resonance imaging was performed at 3 T in 208 patients with long-standing multiple sclerosis (141 females; age = 53.7 ± 9.6 years; disease duration = 20.2 ± 7.1 years) and 60 age- and sex-matched healthy controls. Spatial independent component analysis was performed on cortical thickness maps derived from 3D T1-weighted images across all subjects to identify co-varying patterns. The loadings, which reflect the presence of each cortical thickness pattern in a subject, were compared between patients with multiple sclerosis and healthy controls with generalized linear models. Stepwise linear regression analyses were used to assess whether white matter pathology was associated with these loadings and to identify the cortical thickness patterns that predict measures of physical and cognitive dysfunction. Ten cortical thickness patterns were identified, of which six had significantly lower loadings in patients with multiple sclerosis than in controls: the largest loading differences corresponded to the pattern predominantly involving the bilateral temporal pole and entorhinal cortex, and the pattern involving the bilateral posterior cingulate cortex. In patients with multiple sclerosis, overall white matter lesion load was negatively associated with the loadings of these two patterns. The final model for physical dysfunction as measured with Expanded Disability Status Scale score (adjusted R(2) = 0.297; P atrophy patterns relevant for multiple sclerosis were found. This suggests that

    Human fully upright ambulation, with fully extended hips and knees, and the body's center of gravity directly above the hips, is unique in nature, and distinguishes humans from all other mammalians. This bipedalism is made possible by the development of a lordosis between the ischium and ilium; it allows to ambulate in this unique bipedal manner, without sacrificing forceful extension of the legs. This configuration in space introduces unique biomechanical forces with relevance for a number of spinal conditions. The aim of this study was to quantify the development of this lordosis between ischium and ilium in the normal growing and adult spine and to evaluate its correlation with the well-known clinical parameter, pelvic incidence. Consecutive series of three-dimensional computed tomography scans of the abdomen of 189 children and 310 adults without spino-pelvic pathologies were used. Scan indications were trauma screening or acute abdominal pathology. Using previously validated image processing techniques, femoral heads, center of the sacral endplate and the axes of the ischial bones were semi-automatically identified. A true sagittal view of the pelvis was automatically reconstructed, on which ischio-iliac angulation and pelvic incidence were calculated. The ischio-iliac angle was defined as the angle between the axes of the ischial bones and the line from the midpoint of the sacral endplate to the center of the femoral heads. A wide natural variation of the ischio-iliac angle (3°-46°) and pelvic incidence (14°-77°) was observed. Pearson's analysis demonstrated a significant correlation between the ischio-iliac angle and pelvic incidence (r = 0.558, P lordosis is unique in nature, is in harmonious continuity with the highly individual lumbar lordosis and defines the way the human spine is biomechanically loaded. The practical parameter that reflects this is the pelvic incidence; both values increase during growth and remain stable in adulthood.

    Background and purpose. Many observations on potential inadequate coverage of tumour volume at risk in advanced cervical cancer (CC) when conventional radiation fields are used, have further substantiated by investigators using MRI, CT or lymph-angiographic imaging. This work tries to obtain three dimensional margins by observing enlarged nodes in CT scans in order to improve pelvic nodal chains clinical target volumes (CTVs) drawing, and by looking for corroborative evidence in the literature for a better delineation of tumour CTV. Method. Eleven consecutive patients (seven males, four females, mean age 62 years, range 43 8) with CT diagnosis of nodal involvement caused by pathologically proved carcinoma of the cervix (n = 2), carcinoma of the rectum (n = 2), carcinoma of the prostate (n = 2), non-Hodgkin lymphoma (n 2), Hodgkin lymphoma (n = 1), carcinoma of the penis (n = 1) and carcinoma of the corpus uteri (n = 1) were retrospectively reviewed. Sixty CT scans with 67 enlarged pelvic nodes were reviewed in order to record the more proximal structures (muscle, bone, vessels, cutis or sub-cutis and other organs) to each enlarged node or group of nodes according to the four surfaces (anterior, lateral, posterior and medial) in a clockwise direction. Results. summary of the observations of each nodal chain and the number of occurrences of every marginal structure on axial CT slices is presented. Finally, simple guidelines are proposed. Conclusions. Tumour CTV should be based on individual tumour anatomy mainly for lateral beams as it results from sagittal T2 weighted MRI images. Boundaries of pelvic nodes CTVs can be derived from observations of enlarged lymph nodes in CT scans. (author)

    Full Text Available Introduction: Chronic pelvic pain (CPP is a common medical problem affecting women. Too often the physical signs are not specific. This study aims at determining the accuracy of diagnostic laparoscopy over clinical pelvic examination. Settings and Design: A retrospective study of patients who underwent diagnostic laparoscopy for CPP. Materials and Methods: The medical records of 86 women who underwent laparoscopic evaluation for CPP of at least 6-month duration were reviewed for presentation of symptoms, pelvic examination findings at the admission, operative findings and follow up when available. Statistical analysis used: McNemar Chi-square test for frequencies in a 2 x 2 table. Results: The most common presentation was acyclic lower abdominal pain (79.1%, followed by congestive dysmenorrhoea (26.7%. 61.6% of women did not reveal any significant signs on pelvic examination. Pelvic tenderness was elicited in 27.9%. Diagnostic laparoscopy revealed significant pelvic pathology in 58% of those who essentially had normal pervaginal findings. The most common pelvic pathology by laparoscopy was pelvic adhesions (20.9%, followed by pelvic congestion (18.6%. Laparoscopic adhesiolyis achieved pain relief only in one-third of the women. Conclusion: The study revealed very low incidence of endometriosis (4.7%. Overall clinical examination could detect abnormality in only 38% of women, where as laparoscopy could detect significant pathology in 66% of women with CPP. This shows superiority of diagnostic laparoscopy over clinical examination in detection of aetiology in women with CPP (P < 0.001. Adhesiolysis helps only small proportion of women in achieving pain control.

    Introduction: Chronic pelvic pain (CPP) is a common medical problem affecting women. Too often the physical signs are not specific. This study aims at determining the accuracy of diagnostic laparoscopy over clinical pelvic examination. Settings and Design: A retrospective study of patients who underwent diagnostic laparoscopy for CPP. Materials and Methods: The medical records of 86 women who underwent laparoscopic evaluation for CPP of at least 6-month duration were reviewed for presentation of symptoms, pelvic examination findings at the admission, operative findings and follow up when available. Statistical analysis used: McNemar Chi-square test for frequencies in a 2 × 2 table. Results: The most common presentation was acyclic lower abdominal pain (79.1%), followed by congestive dysmenorrhoea (26.7%). 61.6% of women did not reveal any significant signs on pelvic examination. Pelvic tenderness was elicited in 27.9%. Diagnostic laparoscopy revealed significant pelvic pathology in 58% of those who essentially had normal pervaginal findings. The most common pelvic pathology by laparoscopy was pelvic adhesions (20.9%), followed by pelvic congestion (18.6%). Laparoscopic adhesiolyis achieved pain relief only in one-third of the women. Conclusion: The study revealed very low incidence of endometriosis (4.7%). Overall clinical examination could detect abnormality in only 38% of women, where as laparoscopy could detect significant pathology in 66% of women with CPP. This shows superiority of diagnostic laparoscopy over clinical examination in detection of aetiology in women with CPP (P < 0.001). Adhesiolysis helps only small proportion of women in achieving pain control. PMID:21188008

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

    Full Text Available Abstract Introduction Pelvic actinomycosis constitutes 3% of all human actinomycosis infections. It is usually insidious, and is often mistaken for other conditions such as diverticulitis, abscesses, inflammatory bowel disease and malignant tumors, presenting a diagnostic challenge pre-operatively; it is identified post-operatively in most cases. Here we present a case that presented as pelvic malignancy and was diagnosed as pelvic actinomycosis post-operatively. Case presentation A 48-year-old Caucasian Turkish woman presented to our clinic with a three-month history of abdominal pain, weight loss and difficulty in defecation. She had used an intra-uterine device for 16 years, however it had recently been removed. The rectosigmoidoscopy revealed narrowing of the lumen at 12 cm due to a mass lesion either in the wall or due to an extrinsic lesion that prevented the passage of the endoscope. On examination, there was no gynecological pathology. Magnetic resonance imaging showed a mass, measuring 5.5 × 4 cm attached to the rectum posterior to the uterus. The ureter on that side was dilated. Surgically there was a pelvic mass adhered to the rectum and uterine adnexes, measuring 10 × 12 cm. It originated from uterine adnexes, particularly ones from the left side and formed a conglomerated mass with the uterus and nearby organs; the left ureter was also dilated due to the pelvic mass. Because of concomitant tubal abscess formation and difficulty in dissection planes, total abdominal hysterectomy and bilateral salphingo-oophorectomy was performed (our patient was 48 years old and had completed her childbearing period. The cytology revealed inflammatory cells with aggregates of Actinomyces. Penicillin therapy was given for six months without any complication. Conclusions Pelvic actinomycosis should always be considered in patients with a pelvic mass especially in ones using intra-uterine devices, and who have a history of appendectomy, tonsillectomy

    The aim of this study was to evaluate the frequency of abnormal findings in magnetic resonance imaging (MRI) in children with headache, the clinical relevance of these findings, and whether more sophisticated technologies also result in more relevant abnormal findings. The MRIs of 1004 children with age ranging from 1 to 17 years were retrospectively analyzed. Children who were investigated with established sequences (n = 419) were compared with those examined with state-of-the-art MRI acquisition technology (n = 585). In 216/1004 investigations, MRI was performed because of headache (74/216 with established sequences, 142/216 with state-of-the-art acquisition technology). In 114/216 (52.8%) patients with headache, the MRI was abnormal with relevant findings in 23/114 patients and findings without clinical relevance in 91/114 children. A higher incidence of abnormal findings than in previous reports was found but there was only limited clinical gain of information using modern sequences in children with headache.

    Purpose: To inform radiation treatment planning for clinically staged, node-negative bladder cancer patients by identifying clinical factors associated with the presence and location of occult pathologic pelvic lymph nodes. Methods and Materials: The records of patients with clinically staged T1-T4N0 urothelial carcinoma of the bladder undergoing radical cystectomy and pelvic lymphadenectomy at a single institution were reviewed. Logistic regression was used to evaluate associations between preoperative clinical variables and occult pathologic pelvic or common iliac lymph nodes. Percentages of patient with involved lymph node regions entirely encompassed within whole bladder (perivesicular nodal region), small pelvic (perivesicular, obturator, internal iliac, and external iliac nodal regions), and extended pelvic clinical target volume (CTV) (small pelvic CTV plus common iliac regions) were calculated. Results: Among 315 eligible patients, 81 (26%) were found to have involved pelvic lymph nodes at the time of surgery, with 38 (12%) having involved common iliac lymph nodes. Risk of occult pathologically involved lymph nodes did not vary with clinical T stage. On multivariate analysis, the presence of lymphovascular invasion (LVI) on preoperative biopsy was significantly associated with occult pelvic nodal involvement (odds ratio 3.740, 95% confidence interval 1.865-7.499, P<.001) and marginally associated with occult common iliac nodal involvement (odds ratio 2.307, 95% confidence interval 0.978-5.441, P=.056). The percentages of patients with involved lymph node regions entirely encompassed by whole bladder, small pelvic, and extended pelvic CTVs varied with clinical risk factors, ranging from 85.4%, 95.1%, and 100% in non-muscle-invasive patients to 44.7%, 71.1%, and 94.8% in patients with muscle-invasive disease and biopsy LVI. Conclusions: Occult pelvic lymph node rates are substantial for all clinical subgroups, especially patients with LVI on biopsy. Extended

    Laboratory receiver operating characteristic (ROC) studies, that are often used to evaluate medical imaging systems, differ from “live” clinical interpretations in several respects which could compromise their clinical relevance. The aim was to develop methodology for quantifying the clinical relevance of a laboratory ROC study. A simulator was developed to generate ROC ratings data and binary clinical interpretations classified as correct or incorrect for a common set of images interpreted under clinical and laboratory conditions. The area under the trapezoidal ROC curve was used as the laboratory figure-of-merit and the fraction of correct clinical decisions as the clinical figure-of-merit. Conventional agreement measures (Pearson, Spearman, Kendall and kappa) between the bootstrap-induced fluctuations of the two figures-of-merit were estimated. A jackknife pseudovalue transformation applied to the figures-of-merit was also investigated as a way to capture agreement existing at the individual image level that could be lost at the figure-of-merit level. It is shown that the pseudovalues define a relevance ROC curve the area under which (rAUC) measures the ability of the laboratory figure-of-merit based pseudovalues to correctly classify incorrect vs. correct clinical interpretations, and is a measure of the clinical relevance of an ROC study. The conventional measures and rAUC were compared under varying simulator conditions. It was found that design details of the ROC study, namely the number of bins, the difficulty level of the images, the ratio of disease-present to disease-absent images, and the unavoidable difference between laboratory and clinical performance levels, can seriously underestimate the agreement as indicated by conventional agreement measures, even for perfectly correlated data, while rAUC showed high agreement and was relatively immune to these details. At the same time rAUC was sensitive to factors such as intrinsic correlation between the

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

    Introduction: In recent years, researchers and clinicians do not treat passive suicidal ideation as a clinically relevant risk factor for suicide, while underestimating the strength of this desire to die, compared with making a plan for suicide in individuals having active suicidal ideation. This research study is clinically prospective, cross-sequential, but also partly retrospective because it involves also variables from the past, such as patients’ history data (number of suicidal attempts...

    AIM: To observe the hepatic injury induced by carbon dioxide pneumoperitoneum (CDPP) in rabbits, compare the effffects off low- and high-pressure pneumoperitoneum, and to determine the degree off hepatic injury induced by these two clinically relevant CDPP pressures. METHODS: Thirty healthy male New Zealand rabbits weighing 3.0 to 3.5 kg were randomly divided into three groups (n = 10 ffor each group) and subjected to the ffollowing to CDPP pressures: no gas control, 10 mmHg, or 15 mmHg. Histological changes in liver tissues were observed with hematoxylin and eosin staining and transmission electron microscopy. Liver ffunction was evaluated using an automatic biochemical analyzer. Adenine nucleotide translocator (ANT) activity in liver tissue was detected with the atractyloside-inhibitor stop technique. Bax and Bcl-2 expression levels were detected by western blotting. RESULTS: Liver ffunctions in the 10 mmHg and 15 mmHg experimental groups were significantly disturbed compared with the control group. Affter CDPP, the levels off alanine transaminase and aspartate transaminase were 77.3 ± 14.5 IU/L and 60.1 ± 11.4 IU/L, respectively, in the 10 mmHg experimental group and 165.1 ± 19.4 IU/L and 103.8 ± 12.3 IU/L, respectively, in the 15 mmHg experimental group, which were all higher than those off the control group (PP < 0.05). There was no difffference in pre-albumin concentration between the 10 mmHg experimental group and the control group, but the pre-albumin level off the 15 mmHg experimental group was significantly lower than that of the control group (< 0.05). No significant differences were observed in the levels off total bilirubin or albumin among the three groups. Affter 30 and 60 min off CDPP, pH was reduced (PP < 0.05) and PPaCO2 was elevated (< 0.05) in the 10 mmHg group compared with controls, and these changes were more pronounced in the 15 mmHg group. Hematoxylin and eosin staining showed no significant change in liver morphology, except ffor mild

    Until recently, few molecular signatures of drug resistance identified in drug-induced resistant cancer cell models can be translated into clinical practice. Here, we defined differentially expressed genes (DEGs) between pre-chemotherapy colorectal cancer (CRC) tissue samples of non-responders and responders for 5-fluorouracil and oxaliplatin-based therapy as clinically relevant drug resistance genes (CRG5-FU/L-OHP). Taking CRG5-FU/L-OHP as reference, we evaluated the clinical relevance of several types of genes derived from HCT116 CRC cells with resistance to 5-fluorouracil and oxaliplatin, respectively. The results revealed that DEGs between parental and resistant cells, when both were treated with the corresponding drug for a certain time, were significantly consistent with the CRG5-FU/L-OHP as well as the DEGs between the post-chemotherapy CRC specimens of responders and non-responders. This study suggests a novel strategy to extract clinically relevant drug resistance genes from both drug-induced resistant cell models and post-chemotherapy cancer tissue specimens.

    Pelvic ring fractures are associated with high rates of mortality and thus can provide key information about circumstances surrounding death. These injuries can be particularly informative in skeletonized remains, yet difficult to diagnose and interpret. This study adapted a clinical system of classifying pelvic ring fractures according to their resultant degree of pelvic stability for application to gross human skeletal remains. The modified Tile criteria were applied to the skeletal remains of 22 individuals from the Cleveland Museum of Natural History and Universidad Nacional Autónoma de México that displayed evidence of pelvic injury. Because these categories are tied directly to clinical assessments concerning the severity and treatment of injuries, this approach can aid in the identification of manner and cause of death, as well as interpretations of possible mechanisms of injury, such as those typical in car-to-pedestrian and motor vehicle accidents. © 2014 American Academy of Forensic Sciences.

    Patients with genetic cardiomyopathy that involves myocardial hypertrophy often develop clinically relevant arrhythmias that increase the risk of sudden death. Consequently, guidelines for medical device therapy were established for hypertrophic cardiomyopathy, but not for conditions with only anecdotal evidence of arrhythmias, like Fabry cardiomyopathy. Patients with Fabry cardiomyopathy progressively develop myocardial fibrosis, and sudden cardiac death occurs regularly. Because 24-hour Holter electrocardiograms (ECGs) might not detect clinically important arrhythmias, we tested an implanted loop recorder for continuous heart rhythm surveillance and determined its impact on therapy. This prospective study included 16 patients (12 men) with advanced Fabry cardiomyopathy, relevant hypertrophy, and replacement fibrosis in "loco typico." No patients previously exhibited clinically relevant arrhythmias on Holter ECGs. Patients received an implantable loop recorder and were prospectively followed with telemedicine for a median of 1.2 years (range 0.3 to 2.0 years). The primary end point was a clinically meaningful event, which required a therapy change, captured with the loop recorder. Patients submitted data regularly (14 ± 11 times per month). During follow-up, 21 events were detected (including 4 asystole, i.e., ECG pauses ≥3 seconds) and 7 bradycardia events; 5 episodes of intermittent atrial fibrillation (>3 minutes) and 5 episodes of ventricular tachycardia (3 sustained and 2 nonsustained). Subsequently, as defined in the primary end point, 15 events leaded to a change of therapy. These patients required therapy with a pacemaker or cardioverter-defibrillator implantation and/or anticoagulation therapy for atrial fibrillation. In conclusion, clinically relevant arrhythmias that require further device and/or medical therapy are often missed with Holter ECGs in patients with advanced stage Fabry cardiomyopathy, but they can be detected by telemonitoring with

    Méndez Fernández, R; Barrera Ortega, J

    Endometriosis is common in women of reproductive age; it can cause pelvic pain and infertility. It is important to diagnose endometriosis and to thoroughly evaluate its extension, especially when surgical treatment is being considered. Magnetic resonance imaging (MRI) with careful examination technique and interpretation enables more accurate and complete diagnosis and staging than ultrasonography, especially in cases of deep pelvic endometriosis. Furthermore, MRI can identify implants in sites that can be difficult to access in endoscopic or laparoscopic explorations. In this article, we describe the appropriate MRI protocol for the study of pelvic endometriosis and the MRI signs of pelvic organ involvement. It is necessary to know the subtle findings and to look for them so we can ensure that they are not overlooked. We describe clinical grading systems for endometriosis and review the diagnostic efficacy of MRI in comparison with other imaging techniques and surgery. Copyright © 2017 SERAM.

    Pelvic inflammatory disease and upper genital tract infection describe inflammatory changes in the upper female genital tract of any combination: endometritis, salpingitis, tubo-ovarian abscess and peritonitis in the small pelvis. In most cases the infection is ascending, Chlamydia trachomatis and Neisseria gonorrhoeae are common with increasing incidence. The spectrum ranges from subclinical, asymptomatic infection to severe, life-threatening illness. Antibiotic treatment should be initiated promptly and must cover a broad spectrum of germs. Surgical treatment is necessary in cases of failure of antibiotic treatment and in cases with persisting symptoms after antibiotic treatment. Pelvic inflammatory diseases are one of the main causes of tubal sterility, ectopic pregnancies and chronic abdominal pain.

    INTRODUCTION Despite the vast literature on pelvic fascia, there is confusion over the periprostatic structures and their nomenclature, including their orientation, the neurovascular bundles and the existence of the prostatic ‘capsule’. In this review, we seek to clarify some of these issues. MATERIALS AND METHODS Review of published medical literature relating to the anatomy of the pelvic fascia including a Pubmed search using the terms – pelvic fascia, Denonvilliers' fascia, prostate capsule, neurovascular bundle of Walsh, pubo-prostatic ligament and the detrusor apron. CONCLUSIONS The findings of the study were as follows: The ‘capsule’ of the prostate does not exist. Rather, the fibromuscular band surrounding the prostate forms an integral part of the gland.The prostate is surrounded by fascial structures – anteriorly/anterolaterally by the prostatic fascia and posteriorly by the Denonvilliers' fascia. Laterally, the prostatic fascia merges with the endopelvic fascia.The posterior longitudinal fascia of the detrusor comprises a ‘posterior layer’ of the detrusor apron, extending from the bladder neck to the prostate base.The neurovascular structures tend to be located posterolaterally, but may not always form a bundle. A significant proportion of fibres may lie away from the main nerve structures, along the lateral/posterior aspects of the prostate. PMID:18828961

    2016-03-01

    Full Text Available ABSTRACT Objectives: To demonstrate the recovery of lumbar sagittal pelvic alignment and sagittal pelvic balance after surgical reduction of lumbar spondylolisthesis and establish the benefits of the surgery for reduction and fixation of the lumbar spondylolisthesis with 360o circumferential arthrodesis for 2 surgical approaches by clinical and functional evaluation. Method: Eight patients with lumbar spondylolisthesis treated with surgical reduction and fixation of listhesis and segmental circumferential fusion with two surgical approaches were reviewed. They were evaluated before and after treatment with Oswestry, Visual Analogue for pain and Odom scales, performing radiographic measurement of lumbar sagittal alignment and pelvic sagittal balance with the technique of pelvic radius. Results: Oswestry scales and EVA reported improvement of symptoms after treatment in 8 cases; the Odom scale had six outstanding cases reported. The lumbar sagittal alignment presented a lumbosacral lordosis angle and a lumbopelvic lordosis angle reduced in 4 cases and increased in 4 other cases; pelvic sagittal balance increased the pelvic angle in 4 cases and decreased in 3 cases and the sacral translation of the hip axis to the promontory increased in 6 cases. Conclusion: The surgical procedure evaluated proved to be useful by modifying the lumbar sagittal alignment and the pelvic balance, besides reducing the symptoms, enabling the patient to have mobility and movement and the consequent satisfaction with the surgery.

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

    Awareness of cognitive deficits and clinical competence were investigated in 79 mild to moderate Alzheimer's disease patients. Awareness was assessed by the anosognosia questionnaire for dementia, and clinical competence by specific neuropsychological tests such as trail making test-A, Babcock story recall test, semantic and phonemic verbal fluency. The findings show that 66 % of the patients were aware of memory deficits, while the 34 % were unaware. Deficit in awareness correlated with lower scores on the Mini Mental State Examination test that, in the score range from 24.51 to 30 and from 19.50 to 24.50, appeared to be a significant predictor of level of awareness. None of the AD patients had fully preserved clinical competence, only 7 patients (9 %) had partially preserved clinical competence and 72 patients (91 %) had completely lost clinical competence. All the patients with partially preserved clinical competence (9 %) were aware of their memory deficit. The study indicates that neuropsychological tests used for the assessment of executive functions are not suitable for investigating clinical competence. Therefore, additional and specific tools for the evaluation of clinical competence are necessary. Indeed, these might allow clinicians to identify AD patients who, despite their deficits in selected functions, retain their autonomy of choice as well as recognize those patients who should proceed to the nomination of a legal representative.

    Although magnetic resonance imaging has become the dominant modality for cross-sectional musculo-skeletal imaging, the widespread availability, speed, and versatility of computed tomography (CT) continue to make it a mainstay of emergency room (ER) diagnostic imaging. Pelvic ring and acetabular fractures occur as the result of significant trauma secondary to either a motor vehicle accident or a high-velocity fall. These injuries are correlated with significant morbidity and mortality, both from the complications of pelvic ring fractures and from commonly associated injuries. The most commonly used classification of pelvic and acetabular fractures has been based on conventional radiographs that are, in the majority of cases, sufficient to determine the type of injury. However, because of the complexity of pelvic and acetabular fractures, precise pathological anatomy is not easily demonstrated by routine radiographs and in many cases details of fractures are not visible. Moreover, the insufficient co-operation of the patient or the difficulty of maintaining special positions can be overcome by using computed tomography. Spiral computed tomography provides information regarding the extent of the fractures and is complementary to radiography for ascertaining the spatial arrangement of fracture fragments. Spiral computed tomography is an effective tool for understanding complex fracture patterns, particularly when combined with multi-planar reconstruction two-dimensional (MPR 2D) reformatted images or three-dimensional images (3D) images. Including these techniques of reconstruction in routine pelvic imaging protocols can change management in a significant number of cases. Subtle fractures, particularly those oriented in the axial plane, are better seen on MPR images or 3D volume-rendered images. Complex injuries can be better demonstrated with 3D volume-rendered images, and complicated spatial information about the relative positions of fracture fragments can be easily

    Full Text Available Background: Pelvic lymph node metastasis (LNM is an important prognostic factor in cervical cancer. Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers. Analyses of the effects of the number of positive lymph nodes (LNs, unilateral versus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking. The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence. Methods: We performed a retrospective review of 296 patients diagnosed with Stage IA-IIB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People′s Hospital from November 2004 to July 2013. Ten clinicopathological variables were evaluated as risk factors for pelvic LNM: Age at diagnosis, gravidity, clinical stage, histological grade, tumor diameter, lymph-vascular space involvement (LVSI, depth of cervical stromal invasion, uterine invasion, parametrial invasion, and neoadjuvant chemotherapy. Results: The incidence of pelvic LNM was 20.27% (60/296 cases. Pelvic LNM (P = 0.00 was significantly correlated with recurrence. Pelvic LNM (P = 0.00, the number of positive pelvic LNs (P = 0.04 and a single group versus multiple groups of pelvic LNM (P = 0.03 had a significant influence on survival. Multivariate analysis revealed that LVSI (P = 0.00, depth of cervical stromal invasion (P = 0.00 and parametrial invasion (P = 0.03 were independently associated with pelvic LNM. Conclusions: Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes. Furthermore, more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive IA-IIB cervical squamous cell carcinoma.

    Full Text Available CONTEXT AND OBJECTIVE: Previous studies have shown that women with pelvic floor dysfunctions present decreased cross-sectional area (CSA of the levator ani muscle. One way to assess the effects of training programs is to measure the CSA of the muscle, using ultrasonography. The aim here was to evaluate the efficacy of pelvic floor muscle training and hypopressive exercises for increasing the CSA of the levator ani muscle in women with pelvic organ prolapse. DESIGN AND SETTING: Prospective randomized controlled trial at the Urogynecology outpatient clinic of Universidade Federal de São Paulo. METHODS: Fifty-eight women with stage II pelvic organ prolapse were divided into three groups for physiotherapy: a pelvic floor muscle training group (GI; a hypopressive exercise group (GII; and a control group (GIII. The patients underwent transperineal ultrasonographic evaluation using a transducer of frequency 4-9 MHz. The (CSA of the levator ani muscle was measured before physiotherapy and after 12 weeks of treatment. RESULTS: The groups were homogeneous regarding age, number of pregnancies, number of vaginal deliveries, body mass index and hormonal status. Statistically significant differences in CSA were found in GI and GII from before to after the treatment (P < 0.001, but not in relation to GIII (P = 0.816. CONCLUSIONS: The CSA of the levator ani muscle increased significantly with physiotherapy among the women with pelvic organ prolapse. Pelvic floor muscle training and hypopressive exercises produced similar improvements in the CSA of the levator ani muscle.

  2. Opioid-induced hyperalgesia: is it clinically relevant for the treatment of pain patients?

    2013-09-01

    There is a curious and paradoxic phenomenon, reliably demonstrated in animal models, that consists of an increased sensitivity to pain that is apparently induced by the very opioid drugs used to ameliorate the pain. This phenomenon is termed "opioid-induced hyperalgesia." Whether opioid-induced hyperalgesia occurs in humans, and, if so, to what extent and consequence, is far less established. This is a critical question for attempting to treat pain. If opioid-induced hyperalgesia develops in a patient, it would masquerade as tolerance (because the clinical effectiveness of the opioid would be diminished), yet the appropriate clinical adjustment would be precisely the opposite to that of tolerance. It would be to decrease, rather than increase, the dose of opioid. We review the evidence, particularly the clinical evidence, about opioid-induced hyperalgesia and the postulated mechanisms. We conclude that given the clinical ramifications, opioid-induced hyperalgesia is one of the most understudied important aspects of opioid research.

    Wounds that exhibit delayed healing add extraordinary clinical, economic, and personal burdens to patients, as well as to increasing financial costs to health systems. New interventions designed to ease such burdens for patients with cancer, renal, or ophthalmologic conditions are often cleared for approval by the U.S. Food and Drug Administration (FDA) using multiple endpoints but the requirement of complete healing as a primary endpoint for wound products impedes FDA clearance of interventions that can provide other clinical or patient-centered benefits for persons with wounds. A multidisciplinary group of wound experts undertook an initiative, in collaboration with the FDA, to identify and content validate supporting FDA criteria for qualifying wound endpoints relevant to clinical practice (CP) and patient-centered outcomes (PCO) as primary outcomes in clinical trials. As part of the initiative, a research study was conducted involving 628 multidisciplinary expert wound clinicians and researchers from 4 different groups: the interdisciplinary core advisory team; attendees of the Spring 2015 Symposium on Advanced Wound Care (SAWC); clinicians employed by a national network of specialty clinics focused on comprehensive wound care; and Association for the Advancement of Wound Care (AAWC) and Wound Healing Society (WHS) members who had not previously completed the survey. The online survey assessed 28 literature-based wound care endpoints for their relevance and importance to clinical practice and clinical research. Fifteen of the endpoints were evaluated for their relevance to improving quality of life. Twenty-two endpoints had content validity indexes (CVI) ≥ 0.75, and 15 were selected as meriting potential inclusion as additional endpoints for FDA approval of future wound care interventions. This study represents an important first step in identifying and validating new measurable wound care endpoints for clinical research and practice and for regulatory

    Several musculoskeletal diagnoses are frequently concomitant with pelvic floor pathology and pain. The definition of pelvic pain itself often depends on the medical specialist evaluating the patient. Because there is variability among disorders associated with pelvic pain, patients may seek treatment for extended periods as various treatment options are attempted. Further, health care providers should recognize that there may not be a single source of dysfunction. This article discusses the musculoskeletal disorders of the pelvic girdle (structures within the bony pelvis) and their association with lumbar spine and hip disorders.

    Objective: To assess the spectrum and clinical relevance of extracoronary findings in coronary CT angiography (CCTA), and to compare a small (cardiac) field of view (FOV) to a large (thoracic) FOV setting. Material and methods: 1084 consecutive patients (mean 57 years) with low-to-intermediate risk of coronary artery disease were enrolled. 542 CCTA scans were interpreted with small FOV (160-190 mm{sup 2}) encompassing the cardiac region. In another 542 CCTA (patients matched for age and gender), read-out of an additional full FOV (>320 mm{sup 2}) covering the thorax was performed. Clinical relevance of extracoronary findings was considered as either 'significant' or 'non-significant'. 'Significant' findings were subclassified as either score 1: findings necessitating immediate therapeutic actions, or score 2: findings with undoubted clinical or prognostic relevance, requiring clinical awareness, follow-up or further investigations (non-urgent). 'Non-significant' findings were assigned to either score 3: findings not requiring follow-up or further tests, or as score 4: irrelevant incidental findings. Results: Significantly more patients with extracoronary findings were identified by using a full FOV with 43.2% (234/542) compared to a small FOV with 33.6% (182/542) (p = 0.001). Similarly, a higher total number of extracoronary findings (n = 394) was found on full FOV compared to small FOV (n = 250) (p < 0.001). The detection rate of clinically significant findings was higher by using full FOV compared to small FOV (25.6% versus 15.4%) (p < 0.001), out of those 2.2% versus 1.8% of findings required immediate actions (score 1), and 23.4% versus 13.6% (p = 0.0001), respectively were of clinical relevance (non-urgent, score 2). The rate of malign findings was 0.2%, and of acute pulmonary embolism 0.1%. More lung pathologies were observed by using full FOV compared to small FOV (22% versus 7%) (p < 0.0001), and the detection rate of

    Pelvic inflammatory disease (PID) is commonly encountered in clinical practice. To provide up-to-date guidelines on management of PID. An initial search of the Cochrane database, PubMed, and Embase was performed using keywords related to PID to identify reports in any language published between January 1990 and January 2012, with an update in May 2015. All identified reports relevant to the areas of focus were included. A level of evidence based on the quality of the data available was applied for each area of focus and used for the guidelines. PID must be suspected when spontaneous pelvic pain is associated with induced adnexal or uterine pain (grade C). Pelvic ultrasonography is necessary to exclude tubo-ovarian abscess (grade B). Microbiological diagnosis requires vaginal and endocervical sampling for molecular and bacteriological analysis (grade B). First-line treatment for uncomplicated PID combines ofloxacin and metronidazole for 14days (grade B). Treatment of tubo-ovarian abscess is based on drainage if the collection measures more than 3cm (grade B), with combined ceftriaxone, metronidazole, and doxycycline for 14-21days. Current management of PID requires easily reproducible investigations and treatment, and thus can be applied worldwide. Copyright © 2016 International Federation of Gynecology and Obstetrics.

    Full Text Available BACKGROUND: Recent data showed that a six-domain UPOINT is a flexible and responsive new classification system that has the clinical applicability in CP/CPPS. However, the utility of UPOINT algorithm in men in China with CP/CPPS has not been comprehensively studied. For international validation and adoption, we evaluated this clinical phenotype system for a large cohort of Chinese CP/CPPS patients and correlated it with patient symptoms and erectile dysfunction (ED. We also investigated the addition of an ED domain in regard to symptom correlation. METHODS: A total of 389 Chinese males with CP/CPPS were prospectively collected and classified in each domain of the UPOINT system. Symptom severity was measured using the NIH-CPSI and IPSS. The erectile function was evaluated using the IIEF-5. Clinically relevant associations were calculated. RESULTS: The percentage of patients positive for each domain was 54.0%, 42.1%, 41.9%, 20.8%, 26.7%, and 40.4% for the Urinary, Psychosocial, Organ-specific, Infection, Neurological/systemic, and Tenderness, respectively. There were significant correlations between the number of positive UPOINT domains and total NIH-CPSI (r = 0.706, p<0.001, IPSS (r = 0.682, p<0.001 and IIEF-5 scores (r = 0.631, P = 0.007 in Chinese cohort. Except for patients age, symptom duration was associated with a significantly greater number of positive domains (r = 0.638, P  = 0.005. After adding an ED domain to create a modified UPOINT system, the correlation between the number of phenotypic domains and symptom severity was improved (0.706 to 0.844, p<0.001. CONCLUSIONS: The clinical applicability of using UPOINT phenotyping system has been validated in the Chinese patients with CP/CPPS. In our cohort, the number of positive domains was also correlated with ED symptoms and the significant association between the number of UPOINT domains and NIH-CPSI scores was further refined by adding a domain for ED.

    Patau syndrome (trisomy 13) is one of the most common chromosomal anomalies clinically characterized by the presence of numerous malformations with a limited survival rate for most cases. Babies are usually identified at birth and the diagnosis is confirmed with genetic testing. In this review we outline the clinical and cytogenetic aspects of trisomy 13 and associated phenotypes for 5 cases analyzed in the last 3 years, referred to our Clinical Genetics Department. For each child cytogenetic analysis was performed to determine the genetic variant; also, the patients were investigated for other associated malformations (cardiac, cerebral, renal, ocular anomalies). All 5 cases presented multiple malformations, including some but not all signs of the classical clinical triad suggestive of Patau syndrome. The cytogenetic investigation confirmed for each case the suspected diagnosis and also indicated the specific genetic variant, this being a valuable information for the genetic counselling of the families. The application of genetic analysis can increase diagnosis and prognosis accuracy and have an impact on clinical management.

    Full Text Available Addressing safety concerns such as drug-induced kidney injury (DIKI early in the drug pharmaceutical development process ensures both patient safety and efficient clinical development. We describe a unique adjunct to standard safety assessment wherein the metabolite profile of treated animals is compared with the MetaMap Tox metabolomics database in order to predict the potential for a wide variety of adverse events, including DIKI. To examine this approach, a study of five compounds (phenytoin, cyclosporin A, doxorubicin, captopril, and lisinopril was initiated by the Technology Evaluation Consortium under the auspices of the Drug Safety Executive Council (DSEC. The metabolite profiles for rats treated with these compounds matched established reference patterns in the MetaMap Tox metabolomics database indicative of each compound’s well-described clinical toxicities. For example, the DIKI associated with cyclosporine A and doxorubicin was correctly predicted by metabolite profiling, while no evidence for DIKI was found for phenytoin, consistent with its clinical picture. In some cases the clinical toxicity (hepatotoxicity, not generally seen in animal studies, was detected with MetaMap Tox. Thus metabolite profiling coupled with the MetaMap Tox metabolomics database offers a unique and powerful approach for augmenting safety assessment and avoiding clinical adverse events such as DIKI.

    Miniature swine provide a preclinical model of hematopoietic cell transplantation (HCT) for studies of graft-versus-host disease. HCT between MHC-matched or -mismatched pigs can be performed to mimic clinical scenarios with outcomes that closely resemble those observed in human HCT recipients. With myeloablative conditioning, HCT across MHC barriers is typically fatal, with pigs developing severe (grade III or IV) GVHD involving the gastrointestinal tract, liver, and skin. Unlike rodent models, miniature swine provide an opportunity to perform extended longitudinal studies on individual animals, because multiple tissue biopsies can be harvested without the need for euthanasia. In addition, we have developed a swine GVHD scoring system that parallels that used in the human clinical setting. Given the similarities of GVHD in pigs and humans, we hope that the use of this scoring system facilitates clinical and scientific discourse between the laboratory and the clinic. We anticipate that results of swine studies will support the development of new strategies to improve the identification and treatment of GVHD in clinical HCT scenarios.

    Genetic conditions are individually rare but are common in aggregate, and they often present in the neonatal and early pediatric periods. These conditions are often severe, can be difficult to diagnose and manage, and may heavily affect patients, families, health care systems, and society. Because of recent technological advances, the availability and uptake of genetic and genomic testing are increasing rapidly. However, there is a dearth of trained geneticists and genetic counselors to help guide and explain these conditions and relevant tests. To help hospitalists, neonatologists, and related practitioners navigate this complex and evolving field, we have compiled a list of free (mostly Web-based) resources relevant to the diagnosis and management of genetic conditions and related disorders. These resources, which we describe individually, can be useful for nongeneticist clinicians, and some also include material that can be used to explain concepts and conditions to patients or families. The resources presented are divided into the following categories (which overlap): general information, databases of genetic conditions, resources that can help generate differential diagnoses, databases of genetic testing laboratories (to help with logistics of ordering tests), information on newborn screening, and other resources. We also include a separate list of helpful textbooks and manuals. We conclude with 2 examples describing how some of these resources would be used by a pediatric hospitalist or neonatologist during the inpatient management of a child with a suspected genetic condition.

    Del Rosso, James Q

    2017-03-01

    The author sought to discover why seborrheic keratoses that are not symptomatic or clinically suspicious are not considered therapeutically important to most clinicians. The author conducted an office-based, observational study examining how the diagnosis of asymptomatic seborrheic keratoses personally affects patients and what these patients think concerning treatment. Many patients reported being bothered by the diagnosis of seborrheic keratoses, even when told it's not cancerous, and indicated an interest in its treatment. Lack of insurance coverage for the treatment of non-symptomatic seborrheic keratoses may be the primary reason clinicians do not consider seborrheic keratoses therapeutically important, as clinicians often find the discussion of "self payment" with their patients to be awkward. Furthermore, patients may not understand the implications that "lack of medical necessity" may have on their treatment options. The author describes a clinical approach that may better serve patients and clinicians through the compartmentalization of asymptomatic seborrheic keratoses treatment as a cosmetic procedure within the clinical practice model.

    PCR-based detection of Mucorales species could improve diagnosis of suspected invasive fungal infection, leading to a better patient outcome. This study describes two independent probe-based real-time PCR tests for detection of clinically relevant Mucorales, targeting specific fragments of the 18S and the 28S rRNA genes. Both assays have a short turnaround time, allow fast, specific and very sensitive detection of clinically relevant Mucorales and have the potential to be used as quantitative tests. They were validated on various clinical samples (fresh and formalin-fixed paraffin-embedded specimens, mainly biopsies, n = 17). The assays should be used as add-on tools to complement standard techniques; a combined approach of both real-time PCR assays has 100 % sensitivity. Genus identification by subsequent sequencing is possible for amplicons of the 18S PCR assay. In conclusion, combination of the two independent Mucorales assays described in this study, 18S and 28S, detected all clinical samples associated with proven Mucorales infection (n = 10). Reliable and specific identification of Mucorales is a prerequisite for successful antifungal therapy as these fungi show intrinsic resistance to voriconazole and caspofungin.

    The recent prospect of pharmaceutical interventions for cognitive impairment of Down syndrome (DS) has boosted a number of clinical trials in this population. However, running the trials has raised some methodological challenges and questioned the prevailing methodology used to evaluate cognitive functioning of DS individuals. This is usually achieved by comparing DS individuals to matched healthy controls of the same mental age. We propose a new tool, the TESDAD Battery that uses comparison with age-matched typically developed adults. This is an advantageous method for probing the clinical efficacy of DS therapies, allowing the interpretation and prediction of functional outcomes in clinical trials. In our DS population the TESDAD battery permitted a quantitative assessment of cognitive defects, which indicated language dysfunction and deficits in executive function, as the most important contributors to other cognitive and adaptive behavior outcomes as predictors of functional change in DS. Concretely, auditory comprehension and functional academics showed the highest potential as end-point measures of therapeutic intervention for clinical trials: the former as a cognitive key target for therapeutic intervention, and the latter as a primary functional outcome measure of clinical efficacy. Our results also emphasize the need to explore the modulating effects of IQ, gender and age on cognitive enhancing treatments. Noticeably, women performed significantly better than men of the same age and IQ in most cognitive tests, with the most consistent differences occurring in memory and executive functioning and negative trends rarely emerged on quality of life linked to the effect of age after adjusting for IQ and gender.

    Full Text Available The recent prospect of pharmaceutical interventions for cognitive impairment of Down syndrome(DS has boosted a number of clinical trials in this population. However, running the trials has raised some methodological challenges and questioned the prevailing methodology used to evaluate cognitive functioning of DS individuals. This is usually achieved by comparing DS individuals to matched healthy controls of the same mental age. We propose a new tool, the TESDAD Battery that uses comparison with age-matched typically developed adults. This is an advantageous method for probing the clinical efficacy of DS therapies, allowing the interpretation and prediction of functional outcomes in clinical trials. In our DS population the TESDAD battery permitted a quantitative assessment of cognitive defects, which indicated language dysfunction and deficits in executive function, as the most important contributors to other cognitive and adaptive behavior outcomes as predictors of functional change in DS.

    Full Text Available Introduction and aim of the study: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPSS is a pathology of high prevalence in Italian male population, difficult to diagnose and to treat and with poor response to conventional therapy. Aim of this study was to review the evidence of the literature about the therapeutic effects of a plant product containing flower pollen extracts and group B vitamins on symptoms resolution and amelioration of CP/CPPS patients’ quality of life and to investigate the knowledge among practicing urologists about the clinical application of this product. Materials and methods: A group of 38 urologists was submitted to an investigational survey of the knowledge of the clinical applications of a plant product containing flower pollen extracts and group B vitamins Results: 71% of the urologists interviewed prescribed the plant product for CBP and CP/CPPS at least one time in a month and 11% prescribed it more than 5 times; 67% had evidence of clear ameliorations in pain relief and on patient's quality of life and 47% reported that the effectiveness is comparable to NSAIDs; 39% also reported a significant effect for the improvement of the urinary symptoms of patients. No gastric or general side effects have been noticed during the administration period of this plant product. Finally, the cost of the product has always reported to be sustainable for the patients. Conclusions: From the results of this investigational survey, we can state that the plant product containing flower pollen extracts and group B vitamins is well-known and demonstrated beneficial effects on symptoms resolution and amelioration of quality of life in patients with chronic prostatitis/chronic pelvic pain syndrome.

    Pelvic actinomycosis is an uncommon, slowly progressing granulomatous infection that has been associated with the presence of intrauterine devices. Due to its unspecific clinical and radiologic findings, it can mimic pelvic or intra-abdominal malignancy leading to mutilating surgery of high morbidity. Rarely, diagnosis is made preoperatively and in most cases surgical intervention is necessary. The patient in our case is a 42-year-old female with an IUD for 15 years diagnosed with pelvic actinomycosis. Patient was uniquely diagnosed preoperatively through paracentesis and treated conservatively with prolonged antibiotic therapy and without any type of surgical intervention. Follow-up at 1 year showed almost complete radiologic resolution of the inflammatory mass, nutritional recovery, and absence of symptoms. Pelvic actinomycosis can be successfully diagnosed and treated medically without surgical interventions. PMID:28299218

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

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

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