    Full Text Available Abstract Background Antibody serology is an important tool in the investigation of celiac disease (CD, but does not always correlate with mucosal appearance in the small intestine. Patients with positive CD serology but normal mucosa (Marsh 0 are at increased risk of future CD. In this study we describe a model for identifying and characterizing individuals with normal mucosa but positive CD serology. Such individuals are sometimes referred to as having latent CD. Methods The records of ten Swedish pathology departments were used to identify individuals with biopsies indicating normal duodenal/jejunal mucosa. Using the national personal identification number, these data were linked with CD serology data (antigliadin, antiendomysial and tissue transglutaminase antibodies; and we thereby identified 3,736 individuals with normal mucosa but positive CD serology. Two independent reviewers then manually reviewed their biopsy reports to estimate comorbidity. We also randomly selected 112 individuals for validation through patient chart review. Results The majority of the 3,736 individuals were females (62%. Children (0–15 years made up 21.4%. The median number of biopsy specimen was 3. Our review of biopsy reports found that other gastrointestinal comorbidity was rare (inflammatory bowel disease: 0.4%; helicobacter pylori infection: 0.2%. Some 22% individuals selected for patient chart review had a relative with CD. The most common symptoms among these individuals were diarrhea (46% and abdominal pain (45%, while 26% had anemia. Although 27% of the individuals selected for validation had been informed about gluten-free diet, only 13% were adhering to a gluten-free diet at the end of follow-up. Conclusion Individuals with positive CD serology but normal mucosa often have CD-like symptoms and a family history of CD.

    Objective To determine the type and frequency of neurological signs and symptoms in individuals with fibromyalgia (FM). Methods Persons with FM (n=166) and pain-free controls (n=66) underwent systematic neurological examination by a neurologist blinded to disease status. Neurological symptoms present over the preceding 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurological symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Results Compared to the control group, age and gender adjusted estimates revealed the FM group had significantly more neurological abnormalities in multiple categories including: cranial nerves IX and X (42% vs. 8%), sensory (65% vs. 25%), motor (33% vs. 3%), and gait (28% vs. 7%). Similarly, the FM group endorsed significantly more neurological symptoms than the control group in 27 of 29 categories with the biggest differences observed for photophobia (70% vs. 6%), poor balance (63% vs. 4%), and weakness (58% vs. 2%) and tingling (54% vs. 4%) in the arms and legs. Poor balance, coordination, tingling, weakness in the arms and legs, and numbness in any part of body correlated with appropriate neurological exam findings in the FM group. Conclusions This blinded, controlled study demonstrated neurological physical examination findings in persons with FM. The FM group had more neurological symptoms than controls, with moderate correlation between symptoms and signs. These findings have implications for the medical work-up of patients with FM.

    To determine the type and frequency of neurologic signs and symptoms in individuals with fibromyalgia (FM). Persons with FM (n = 166) and pain-free controls (n = 66) underwent systematic neurologic examination by a neurologist blinded to disease status. Neurologic symptoms lasting at least 3 months were assessed with a standard questionnaire. We used logistic regression to evaluate the association of neurologic symptoms and examination findings with FM status. Within the FM group we examined the correlation between self-reported symptoms and physical examination findings. Age- and sex-adjusted estimates revealed that compared with the control group, the FM group had significantly more neurologic abnormalities in multiple categories, including greater dysfunction in cranial nerves IX and X (42% versus 8%) and more sensory (65% versus 25%), motor (33% versus 3%), and gait (28% versus 7%) abnormalities. Similarly, the FM group had significantly more neurologic symptoms than the control group in 27 of 29 categories, with the greatest differences observed for photophobia (70% versus 6%), poor balance (63% versus 4%), and weakness (58% versus 2%) and tingling (54% versus 4%) in the arms or legs. Poor balance or coordination, tingling or weakness in the arms or legs, and numbness in any part of the body correlated with appropriate neurologic examination findings in the FM group. This blinded, controlled study demonstrated neurologic physical examination findings in persons with FM. The FM group had more neurologic symptoms than did the controls, with moderate correlation between symptoms and signs. These findings have implications for the medical evaluation of patients with FM.

    2002-01-01

    The aim of the study was to consider Kimmerle anomaly (ponticulus posterior of the atlas) as an anatomic variant, which can cause a set of clinical symptoms and signs. A hundred and eight patients, 58 females and 50 males at the age of 18-59 years (M. 36.9 years, SD = 9.6) with radiologically verified Kimmerle anomaly were examined. A control group comprised 40 healthy subjects at the similar age range. The diagnosis of headaches was based on the criteria proposed by the IHS. A character of headaches, their localization, frequency, duration, number of days with headaches per year, circumstances associated with their onset and concomitant symptoms were evaluated. All the patients were subjected to electrophysiological studies (ENG, EEG and VEP). The results were statistically analyzed using a SPSS/PC+ computer system. It was revealed that clinical symptoms and signs in Kimmerle anomaly occurred most frequently in the third and fourth decade of life (65% of cases). These were most often tension-type headaches (50% of cases with headaches), vascular headaches (26% of cases) and neuralgia (24% of cases). Intensity of headaches was high. Headaches were accompanied by other complaints like vertigo (59% of cases) and in one third of cases--nausea. About 10% of patients also suffered from vomiting, paresthesia, dizziness, short periods of loss of consciousness. Sporadically--tinitus, drop attack, and vegetative symptoms. In cases without pain the most frequent signs were short periods of loss of consciousness, dizziness, and also nausea and dizziness. The EEG examination revealed pathology in 40% of patients with Kimmerle anomaly. The ENG examination in more than 33% of anomaly cases showed injury in the central part of vestibular system. Improper answers were reported in about 75% of the patients during the VEP examination.

    The percentage of children who are symptomatic has been shown to increase with the number of signs of convergence insufficiency (CI). Our goal was to investigate whether there is a relationship between the severity of the clinical signs of CI and symptom level reported in children with a three-sign symptomatic CI. The Convergence Insufficiency Treatment Trial enrolled 221 children with symptomatic CI from ages 9 to 17 years. Inclusion criteria included the following three signs of CI: (1) exophoria at near at least 4Δ greater than at distance, (2) insufficient positive fusional vergence (PFV) at near, and (3) a receded near point of convergence (NPC) of 6 cm break or greater. The relationships between the severity of each sign of CI (mild, moderate, and severe) and the level of symptoms as measured by the Convergence Insufficiency Symptom Survey (CISS) at baseline were evaluated. Mean CISS scores were not significantly different between mild, moderate, and severe exophoria (p = 0.60), PFV blur (p = 0.99), Sheard's criterion (p = 0.89), or NPC break (p = 0.84). There was also no difference between the frequency of subjects scoring at mild, moderate, or severe levels on the CISS and the severity of each sign of CI. Correlations between individual clinical signs and the CISS score were very low and not statistically significant. Among symptomatic children with a CISS score of 16 or higher and three clinical signs of CI, there is no further association between the severity of the clinical signs and their level of symptoms.

    The frequent lack of association between dry eye (DE) symptoms and signs leads to challenges in diagnosing and assessing the disease. Participants underwent ocular surface examinations to evaluate signs of disease and completed questionnaires to assess ocular symptoms, psychological status and medication use. To assess nociceptive system integrity, quantitative sensory testing (QST), including vibratory and thermal threshold measures and temporal summation of pain were obtained at the forearm and forehead. Correlations between DE discordance score (degree of discrepancy between symptom severity and DE signs) and patient characteristics were determined. Higher discordance scores indicated more symptoms than signs. 326 patients participated (mean age: 62 years; SD: 10 years; 92% men). Age was negatively correlated with DE discordance score (Pearson r=-0.30, p<0.0005), while mental health indices were positively correlated. Chronic pain elsewhere in the body (ie, non-ocular pain conditions) and intensity ratings of prolonged aftersensations of pain evoked by noxious hot and cold stimuli were also significantly correlated with DE discordance score. Multiple linear regression demonstrated that post-traumatic stress disorder and non-ocular pain intensity were important predictors of DE discordance score, Dry Eye Questionnaire-5 and Ocular Surface Disease Index and that DE discordance was also sensitive to QST as well. The present study provides evidence that the degree of discordance between DE symptom report and measurable signs of ocular surface disease is associated with comorbidities related to clinical pain and to hyperalgesia as demonstrated with QST. Understanding the epidemiology of DE discordance can aid in interpreting the DE exam and individualising treatment. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Justin John Gandy, Ilze Laurens, Jacques Rene Snyman Department of Pharmacology, School of Medicine, Faculty of Health Sciences, University of Pretoria, Pretoria, Gauteng, South Africa Introduction: Abundant anecdotal evidence for products claiming to reduce veisalgia after alcohol overindulgence are available on the Internet and as many advertisements in journals. None of these claims are, however, substantiated by research. The aim of this research was to ascertain the validity of such claims for the substance Absorbatox™, a potentiated aluminosilicate (cation exchanger able to bind NH4+, histamine, and other positively charged ions by investigating the signs and symptoms, as well as blood or breath alcohol levels, in healthy volunteers. Methods: Blood or breath alcohol levels were measured in all volunteers in initial controlled experiments, and symptoms were scored on a diary card for gastrointestinal tract symptoms, as well as other symptoms such as headache and light sensitivity. Eighteen volunteers completed the initial blood alcohol study, which investigated the effect of Absorbatox™ on blood alcohol levels after fasting. The follow-up studies researched the effects of the symptoms and signs of alcohol overindulgence. The “night out” study was completed by ten volunteers in a typical controlled environment, which was followed by the real-life four-leg crossover study. In the crossover study, volunteers (number =25 completers had to fill matching diary cards to containers of two placebo and two active drugs after a night out where they themselves decided on the container (color coded to be used and the amount of alcohol to be consumed. Results: Absorbatox™ had no effect on blood alcohol levels, but it significantly reduced the symptoms and signs of veisalgia by approximately 40%–50%. Conclusion: This research indicates that Absorbatox™ does not have an effect on blood- or breath-alcohol levels. Furthermore, treatment with

    The purpose of this study was to, in a pediatric population, describe the frequency of opioid withdrawal signs and symptoms and to identify factors associated with these opioid withdrawal signs and symptoms. Opioids are used routinely in the pediatric intensive care population for analgesia, sedation, blunting of physiologic responses to stress, and safety. In children, physical dependence may occur in as little as 2-3 days of continuous opioid therapy. Once the child no longer needs the opioid, the medications are reduced over time. A prospective, descriptive study was conducted. The sample of 26 was drawn from all patients, ages 2 weeks to 21 years admitted to the Children's Hospital of Richmond pediatric intensive care unit (PICU) and who have received continuous infusion or scheduled opioids for at least 5 days. Data collected included: opioid withdrawal score (WAT-1), opioid taper rate (total dose of opioid per day in morphine equivalents per kilogram [MEK]), pretaper peak MEK, pretaper cumulative MEK, number of days of opioid exposure prior to taper, and age. Out of 26 enrolled participants, only 9 (45%) had opioid withdrawal on any given day. In addition, there was limited variability in WAT-1 scores. The most common symptoms notes were diarrhea, vomit, sweat, and fever. For optimal opioid withdrawal assessments, clinicians should use a validated instrument such as the WAT-1 to measure for signs and symptoms of opioid withdrawal. Further research is indicated to examine risk factors for opioid withdrawal in children. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Background Inflammatory Bowel Disease is known for its extra intestinal manifestations, the oral cavity is no exception. Objectives The aim of this study was to evaluate the association between Inflammatory Bowel Disease and oral mucosa lesions and symptoms, and complementary to evaluate their possible relation with oral hygiene, smoking habits, drug therapy, duration and activity of the disease. Methods Patients were selected from the Gastroenterology Clinic of a Portuguese tertiary referral hospital. This sample consisted of 113 patients previously diagnosed with ulcerative colitis or Crohn’s disease along with a control group of 58 healthy individuals that were accompanying the study group patients to their appointments. Clinical interviews and clinical examinations were performed for data collection. Results The patients in the study group were more affected by oral symptoms (P=0.011, and showed a trend towards a higher incidence of oral mucosal lesions, even though statistical significance was not reached (8.8% versus 3.4% in the control group; P=0.159. Patients in active phase were the most affected. No differences were detected between Crohn’s disease and ulcerative colitis, or concerning smoking habits. The corticosteroid and immunosuppressant therapy seemed to increase the incidence of oral symptoms (P=0.052. The oral mucosa lesions increased and the oral symptoms decreased over the course of the disease, however without statistical significance. Conclusion Oral mucosa’s lesions and oral symptoms were positively associated with Inflammatory Bowel Disease, mainly during disease activity periods and conceivably, associated with corticosteroid and immunosuppressant therapy.

    To evaluate the degree of identification of main signs and symptoms of streptococcal pharyngitis by resident doctors, general practitioners, family physicians and pediatricians. A prospective, cross-sectional and comparative study was done. A validated questionnaire was applied including the following topics: social demographic, main signs and symptoms, clinical cases; and clinical pictures. We interviewed resident doctors (n = 40), general physicians (n = 21), family physicians (n = 35) and pediatricians (n = 19) from different institutions (SSa, ISSSTE, IMSS) in Guadalajara, Mexico, from March to August 2005. Scores were interpreted as very good, good, regular and poor, and these scores were related with the specialty and clinical years of experience. chi2, student t test and linear regression. This study included 115 physicians between 22 to 60 years old (mean = 39) and with 0 to 31 (mean = 10) clinical years of experience. Regarding the conceptual identification of main signs and symptoms, tonsil exudates were recognized by 33 to 61% of physicians, and a clinical case of streptococcal tonsillitis was recognized by 50 to 70%. A clinical picture of tonsil caseum was misinterpreted as streptococcal tonsillitis by 13 to 35% of the physicians. There was no association between years of clinical experience and the scores obtained in clinical cases (r = 0.20) or clinical pictures (r = 0.09). The clinical identification of streptococcal tonsillitis was regular to poor among all the interviewed physicians, and there had no correlation with the years of clinical experience. The reinforcement in teaching to recognize the key signs and symptoms of streptococcal tonsillitis at medical school would result in better recognition, more rational use of antimicrobials and reduction in health institutions costs.

    Women are more likely to present temporomandibular disorders (TMD); however, studies comparing genders in Brazilian samples are rare. To analyze the proportion of men and women, as well as the association between gender and age, problem duration, and TMD symptoms in patients admitted to an university clinic for treatment. Interview and assessment data of protocols from 1,000 patients diagnosed with TMD were collected and analyzed and then divided into two groups, male (n = 177) and female (n = 823). The exploratory analysis was based on contingency tables and χ2 test was carried out. Subsequently, the logistic regression model was used and the odds ratios (OR) concerning the evaluated comparisons were calculated. Females were more prevalent in the sample, and mean ages and TMD duration were similar between the groups, with higher occurrence in young adults (19 to 40 years old). The OR values showed an association between the female gender and the signs/symptoms of pain in the temporomandibular joint, pain in the facial muscles, neck and shoulders, headache, fatigue in the muscles of mastication, otologic symptoms, and dysphonia. Women had two times higher chances of presenting these symptoms than men. In the sample of Brazilian patients with TMD, the number of women who presented a higher prevalence of painful symptoms was greater, followed by otologic symptoms and complaints of dysphonia. The prevalence of joint noise was similar in both studied groups.

    To determine the chest radiographic findings in patients of adult neurotuberculosis, with no pulmonary signs and symptoms. A total of 100 patients fulfilling pre-defined criteria of neurotuberculosis were included. Chest radiographic (CXR) evidence of pulmonary TB was looked for in those patients and its frequency, pattern and association with the clinical grades at presentation was determined by using Chi-square test. Out of the 100 patients of neurotuberculosis, with no clinical evidence of pulmonary TB, radiographic evidence of pulmonary TB was seen in only 30% patients. The predominant patterns on CXR were apical infiltration (26.6%), military mottling (20%) and hilar enlargement (16.6%). Positive CXR was found in 16.7% patients in clinical grade I and 40% and 43.3% in patients in grade II and III respectively. There was a strong association of grade II and grade III with positive chest radiographic findings (p= 0.03). Patients of neurotuberculosis may have chest radiographic evidence of pulmonary TB even in the absence of pulmonary signs and symptoms at presentation. There is a strong association of clinical grade II and grade III with positive chest radiographic findings. (author)

  4. Cushing's syndrome: update on signs, symptoms and biochemical screening.

    2015-10-01

    Endogenous pathologic hypercortisolism, or Cushing's syndrome, is associated with poor quality of life, morbidity, and increased mortality. Early diagnosis may mitigate against this natural history of the disorder. The clinical presentation of Cushing's syndrome varies, in part related to the extent and duration of cortisol excess. When hypercortisolism is severe, its signs and symptoms are unmistakable. However, most of the signs and symptoms of Cushing's syndrome are common in the general population (e.g., hypertension and weight gain) and not all are present in every patient. In addition to classical features of glucocorticoid excess, such as proximal muscle weakness and wide purple striae, patients may present with the associated comorbidities that are caused by hypercortisolism. These include cardiovascular disease, thromboembolic disease, psychiatric and cognitive deficits, and infections. As a result, internists and generalists must consider Cushing's syndrome as a cause, and endocrinologists should search for and treat these comorbidities. Recommended tests to screen for Cushing's syndrome include 1  mg dexamethasone suppression, urine free cortisol, and late night salivary cortisol. These may be slightly elevated in patients with physiologic hypercortisolism, which should be excluded, along with exogenous glucocorticoid use. Each screening test has caveats and the choice of tests should be individualized based on each patient's characteristics and lifestyle. The objective of this review is to update the readership on the clinical and biochemical features of Cushing's syndrome that are useful when evaluating patients for this diagnosis. © 2015 European Society of Endocrinology.

    2016-06-01

    Full Text Available Abstract Objective: The abnormalities of the genitourinary tract development are the leading cause of chronic kidney disease (CKD in children. The diagnosis of this disease in Brazil is late and incomplete, which results in increased morbidity and mortality in this age group. Early diagnosis of this condition is the prerogative of generalist pediatricians, and the aim of this study was to review the clinical signs and symptoms associated with developmental abnormalities of the genitourinary tract. Data sources: Based on the description of a symbolic clinical case, the authors conducted a non-systematic review of medical literature. Data synthesis: The results suggest that the following data should be used as a warning for early diagnosis of affected children: (a combined urinary tract abnormalities (chromosomal abnormalities; sequence of malformations [VACTERLand Prune-Belly]; and musculoskeletal, digestive tract, heart, and nervous system malformations; (b previous history (congenital anomalies of the kidney and urinary tract [CAKUT] in the family, low birth weight, and oligoamnios; (c clinical signs (polyuria/nocturia, urinary tract infection, systemic arterial hypertension, failure to thrive, weak urinary stream, difficulty to start urination, distended bladder, non-monosymptomatic enuresis, urinary/urge incontinence, and bowel and bladder dysfunction; and (d pre- and postnatal ultrasonographic alterations (increased anteroposterior diameter of the renal pelvis, mainly in the third trimester of pregnancy; single kidney; hydronephrosis associated with other abnormalities; and hydronephrosis with parenchymal involvement in the post-neonatal assessment. Conclusion: The suggestions shown here can help the pediatrician to establish clinical hypotheses for the early diagnosis of developmental abnormalities of the genitourinary tract without resorting to expensive and invasive procedures.

    This study investigated the prevalence of Temporomandibular Disorders (TMD) in the elderly and its association with palpation of the temporomandibular joint (TMJ), masticatory and cervical muscles as well as the presence of headache and joint noises. The sample consisted of 200 elderly of both genders (mean age: 69.2±5.7 years). The clinical evaluation of TMD signs and symptoms was divided into three stages: an anamnestic questionnaire, a TMJ evaluation, and a muscular examination. The results were analyzed through descriptive statistics as well as using χ2 and the tendency tests. The presence of TMD was observed in 61% of the sample (mild: 43.5%, moderate: 13%, severe: 4.5%). A significantly greater prevalence of TMD was found for females (72.4%) compared with that for men (41.1%) (pheadaches and the presence of TMD (p=0.0001). The association between the presence of joint noises and sensitivity to TMJ palpation was not significant. The elderly presented high TMD prevalence, mostly in females, with mild severity and related to TMJ and masticatory/cervical muscles palpation. Thus, the accomplishment of a detailed clinical examination to investigate the presence of such disorders is essential and it must not be neglected during the treatment of elderly patients.

    2016-05-01

    Full Text Available Objective: The abnormalities of the genitourinary tract development are the leading cause of chronic kidney disease (CKD in children. The diagnosis of this disease in Brazil is late and incomplete, which results in increased morbidity and mortality in this age group. Early diagnosis of this condition is the prerogative of generalist pediatricians, and the aim of this study was to review the clinical signs and symptoms associated with developmental abnormalities of the genitourinary tract. Data sources: Based on the description of a symbolic clinical case, the authors conducted a non-systematic review of medical literature. Data synthesis: The results suggest that the following data should be used as a warning for early diagnosis of affected children: (a combined urinary tract abnormalities (chromosomal abnormalities; sequence of malformations [VACTERLand Prune-Belly]; and musculoskeletal, digestive tract, heart, and nervous system malformations; (b previous history (congenital anomalies of the kidney and urinary tract [CAKUT] in the family, low birth weight, and oligoamnios; (c clinical signs (polyuria/nocturia, urinary tract infection, systemic arterial hypertension, failure to thrive, weak urinary stream, difficulty to start urination, distended bladder, non-monosymptomatic enuresis, urinary/urge incontinence, and bowel and bladder dysfunction; and (d pre- and postnatal ultrasonographic alterations (increased anteroposterior diameter of the renal pelvis, mainly in the third trimester of pregnancy; single kidney; hydronephrosis associated with other abnormalities; and hydronephrosis with parenchymal involvement in the post-neonatal assessment. Conclusion: The suggestions shown here can help the pediatrician to establish clinical hypotheses for the early diagnosis of developmental abnormalities of the genitourinary tract without resorting to expensive and invasive procedures.

    To evaluate the response of the vaginal mucosa with TX-004HR and its correlation with vulvar and vaginal atrophy (VVA) symptoms, and whether visual examination is a useful measure for assessing VVA. REJOICE was a 12-week, phase 3, multicenter, randomized, double-blind, placebo-controlled study of a vaginal, muco-adhesive, 17β-estradiol softgel capsule (TX-004HR 4, 10, and 25 μg) in postmenopausal women with VVA and moderate-to-severe dyspareunia. Treatments were self-administered vaginally once per day for 2 weeks, then twice per week for 10 weeks. The vagina was visually examined at baseline and at weeks 2, 6, 8, and 12; changes were evaluated using a 4-item scale for vaginal color, vaginal epithelial integrity, vaginal epithelial surface thickness, and vaginal secretions. Significant improvements were observed with all three TX-004HR doses versus placebo in vaginal color (least square mean score changes of -0.96 to -1.06 for TX-004HR doses vs -0.60 for placebo at week 12), epithelial integrity (-0.97 to -1.07 vs -0.60), epithelial surface thickness (-0.94 to -1.03 vs -0.61), and secretions (-1.01 to -1.06 vs -0.64) (P vaginal dryness (P vaginal mucosa of postmenopausal women with VVA and moderate-to-severe dyspareunia were observed with TX-004HR versus placebo, and vaginal mucosa assessment scores correlated with vaginal symptoms of dyspareunia and dryness. Visual vaginal assessment by healthcare professionals is a useful measure for diagnosing VVA and assessing response to treatment.

    2010-09-01

    To analyze whether gender, self-reported bruxism, and variations in dental occlusion predicted incidence and persistence of temporomandibular disorder (TMD) during a 2-year period. The study population comprised 280 dental students at Umeå University in Sweden. The study design was that of a case-control study within a 2-year prospective cohort. The investigation comprised a questionnaire and a clinical examination at enrolment and at 12 and 24 months. Cases (incidence) and controls (no incidence) were identified among those without signs and symptoms of TMD at the start of the study. Cases with 2-year persistence of signs and symptoms of TMD were those with such signs and symptoms at all three examinations. Clinical registrations of baseline variables were used as independent variables. Odds ratio estimates and 95% confidence intervals of the relative risks of being a case or control in relation to baseline registrations were calculated using logistic regression analyses. The analyses revealed that self-reported bruxism and crossbite, respectively increased the risk of the 2-year cumulative incidence and duration of temporomandibular joint (TMJ) signs or symptoms. Female gender was related to an increased risk of developing and maintaining myofascial pain. Signs of mandibular instability increased the risk of maintained TMD signs and symptoms during the observation period. This 2-year prospective observational study indicated that self-reported bruxism and variations in dental occlusion were linked to the incidence and persistence of TMJ signs and symptoms to a higher extent than to myofascial pain.

    2006-04-01

    Full Text Available Background Gastroesophageal reflux disease (GERD is very common in developed world, with the prevalence of disease is between 6 and 20%. Pathologic reflux can provoke not only typical symptoms (heartburn and regurgitation but also atypical symptoms and diseases of extraoesophageal organs (pulmonary, ENT, mouth. High prevalence of GERD in patients with unexplained chest pain, asthma, chronic cough, chronic laryngitis, hoarsness and dental erosions is not a proof of causality. GERD can cause these diseases with reflux of acid and pepsin into pharynx, larynx, lungs and mouth (reflux theory or through vasovagal mechanisms (reflex theory. Conclusions Good therapeutic success with medical or operative treatment in early methodologically not well conducted studies has not been completely proven in double-blind placebo controlled studies. GERD is an ethyological reason for these extraoesophageal symptoms and diseases in an approximately one third of patients. With diagnostic modalities that we have now, we cannot clearly define in which patient is GERD is an ethyologic factor or a contributer, before we start the treatment. In patients suspected of having GERD, there is therapeutic option of a trial with high dose of proton pump inhibitor for 3 to 6 months. In other patients with low clinical suspicion of GERD, 24-hour pH testing should be done first.

    This study was designed to evaluate the common signs and symptoms of hypothyroidism in persons with clinical diagnosis of hypothyroidism that was confirmed with laboratory tests. This descriptive cross-sectional study was done during 13 months in medical centers of Shahrood city, in central part of Iran. All cases with probable diagnosis of hypothyroidism based on the signs and symptoms, referred to health care services were included in the study. Radioimmunoassay tests and thyroid hormones evaluation were done. Demographic data and signs were recorded through interview. Data were entered in the computer and analyzed by SPSS software. Patients who completed questionnaires (n=50) were interviewed three times during this period. Female/male ratio was 6/1. The most common signs were cold intolerance (95%), weight gain and menorrhagia. The most common symptoms were edema (80%) and pallor (60%). The severe disease was seen in 4%. Mild type was the most common presentation of hypothyroidism (60%). The most common signs and symptoms of hypothyroidism in the central part of Iran (Shahrood city), that is one of the iodine deficient areas in Iran; were different from other studies. Socio-demographic and nutritional status, illiteracy level and personal self-care are among the probable causes. Unfortunately, concomitance of some of the signs and symptoms are not diagnostic for hypothyroidism. It seems that strong clinical suspicious and laboratory confirmation are the only reliable methods for hypothyroidism diagnosis. (author)

  18. About signs and symptoms: can semiotics expand the view of clinical medicine?

    Science.gov (United States)

    Nessa, J

    1996-12-01

    Semiotics, the theory of sign and meaning, may help physicians complement the project of interpreting signs and symptoms into diagnoses. A sign stands for something. We communicate indirectly through signs, and make sense of our world by interpreting signs into meaning. Thus, through association and inference, we transform flowers into love, Othello into jealousy, and chest pain into heart attack. Medical semiotics is part of general semiotics, which means the study of life of signs within society. With special reference to a case story, elements from general semiotics, together with two theoreticians of equal importance, the Swiss linguist Ferdinand de Saussure and the American logician Charles Sanders Peirce, are presented. Two different modes of understanding clinical medicine are contrasted to illustrate the external link between what we believe or suggest, on the one hand, and the external reality on the other hand.

    Full Text Available Aim. To determine the level of knowledge of signs and symptoms of heart attack and stroke in Singapore resident population, in comparison to the global community. Methods. A population based, random sample of 7,840 household addresses was selected from a validated national sampling frame. Each participant was asked eight questions on signs and symptoms of heart attack and 10 questions on stroke. Results. The response rate was 65.2% with 4,192 respondents. The level of knowledge for preselected, common signs and symptoms of heart attack and stroke was 57.8% and 57.1%, respectively. The respondents scored a mean of 5.0 (SD 2.4 out of 8 for heart attack, while they scored a mean of 6.8 (SD 2.9 out of 10 for stroke. Respondents who were ≥50 years, with lower educational level, and unemployed/retired had the least knowledge about both conditions. The level of knowledge of signs and symptoms of heart attack and stroke in Singapore is comparable to USA and Canada. Conclusion. We found a comparable knowledge of stroke and heart attack signs and symptoms in the community to countries within the same economic, educational, and healthcare strata. However older persons, those with lower educational level and those who are unemployed/retired, require more public health education efforts.

    Objective: To determine the incidence, timing, and severity of neurologic findings in acute HIV infection (pre–antibody seroconversion), as well as persistence with combination antiretroviral therapy (cART). Methods: Participants identified with acute HIV were enrolled, underwent structured neurologic evaluations, immediately initiated cART, and were followed with neurologic evaluations at 4 and 12 weeks. Concurrent brain MRIs and both viral and inflammatory markers in plasma and CSF were obtained. Results: Median estimated HIV infection duration was 19 days (range 3–56) at study entry for the 139 participants evaluated. Seventy-three participants (53%) experienced one or more neurologic findings in the 12 weeks after diagnosis, with one developing a fulminant neurologic manifestation (Guillain-Barré syndrome). A total of 245 neurologic findings were noted, reflecting cognitive symptoms (33%), motor findings (34%), and neuropathy (11%). Nearly half of the neurologic findings (n = 121, 49%) occurred at diagnosis, prior to cART initiation, and most of these (n = 110, 90%) remitted concurrent with 1 month on treatment. Only 9% of neurologic findings (n = 22) persisted at 24 weeks on cART. Nearly all neurologic findings (n = 236, 96%) were categorized as mild in severity. No structural neuroimaging abnormalities were observed. Participants with neurologic findings had a higher mean plasma log10 HIV RNA at diagnosis compared to those without neurologic findings (5.9 vs 5.4; p = 0.006). Conclusions: Acute HIV infection is commonly associated with mild neurologic findings that largely remit while on treatment, and may be mediated by direct viral factors. Severe neurologic manifestations are infrequent in treated acute HIV. PMID:27287217

    Akinetic mutism is thought to be an appropriate therapeutic end-point in patients with sporadic Creutzfeldt-Jakob disease (sCJD). However, prognostic factors for akinetic mutism are unclear and clinical signs or symptoms that precede this condition have not been defined. The goal of this study was to identify prognostic factors for akinetic mutism and to clarify the order of clinical sign and symptom development prior to its onset. The cumulative incidence of akinetic mutism and other clinical signs and symptoms was estimated based on Japanese CJD surveillance data (455 cases) collected from 2003 to 2008. A proportional hazards model was used to identify prognostic factors for the time to onset of akinetic mutism and other clinical signs and symptoms. Periodic synchronous discharges on electroencephalography were present in the majority of cases (93.5%). The presence of psychiatric symptoms or cerebellar disturbance at sCJD diagnosis was associated with the development of akinetic mutism [hazard ratio (HR) 1.50, 95% confidence interval (CI) 1.14-1.99, and HR 2.15, 95% CI1.61-2.87, respectively]. The clinical course from cerebellar disturbance to myoclonus or akinetic mutism was classified into three types: (i) direct path, (ii) path via pyramidal or extrapyramidal dysfunction and (iii) path via psychiatric symptoms or visual disturbance. The presence of psychiatric symptoms or cerebellar disturbance increased the risk of akinetic mutism of sCJD cases with probable MM/MV subtypes. Also, there appear to be sequential associations in the development of certain clinical signs and symptoms of this disease. © 2016 The Authors.

    In this prospective study, we evaluated the effect of gluten-free diet (GFD) in a cohort of 65 children with potential celiac disease. Patients received GFD for signs/symptoms (N = 47) or parents' choice (N = 18). Most frequent signs/symptoms were low body mass index (36%), recurrent abdominal pain (34%), and diarrhea (19%). Of the 35/47 patients followed-up on GFD, only 54% (19/35) showed a complete clinical response. In 9 of 65 patients an intestinal biopsy was also performed after at least 1 year of GFD. No significant differences were observed in terms of Marsh grade (P = 0.33), lamina propria CD25+ cells (P = 0.80), CD3+ (P = 0.9), and γδ+ (P = 0.59) intraepithelial lymphocytes density and intestinal anti-TG2 deposits (P = 0.60). In conclusion, caution is necessary before attributing all symptoms to gluten in this condition.

    2005-08-01

    Full Text Available Abstract Background Early diagnosis of serious infections in children is difficult in general practice, as incidence is low, patients present themselves at an early stage of the disease and diagnostic tools are limited to signs and symptoms from observation, clinical history and physical examination. Little is known which signs and symptoms are important in general practice. With this qualitative study, we aimed to identify possible new important diagnostic variables. Methods Semi-structured interviews with parents and physicians of children with a serious infection. We investigated all signs and symptoms that were related to or preceded the diagnosis. The analysis was done according to the grounded theory approach. Participants were recruited in general practice and at the hospital. Results 18 children who were hospitalised because of a serious infection were included. On average, parents and paediatricians were interviewed 3 days after admittance of the child to hospital, general practitioners between 5 and 8 days after the initial contact. The most prominent diagnostic signs in seriously ill children were changed behaviour, crying characteristics and the parents' opinion. Children either behaved drowsy or irritable and cried differently, either moaning or an inconsolable, loud crying. The parents found this illness different from previous illnesses, because of the seriousness or duration of the symptoms, or the occurrence of a critical incident. Classical signs, like high fever, petechiae or abnormalities at auscultation were helpful for the diagnosis when they were present, but not helpful when they were absent. Conclusion behavioural signs and symptoms were very prominent in children with a serious infection. They will be further assessed for diagnostic accuracy in a subsequent, quantitative diagnostic study.

    Introduction In contrast to the premonitory phase of migraine, little is known about the pre-attack (prodromal) phase of a cluster headache. We aimed to describe the nature, prevalence, and duration of pre-attack symptoms in cluster headache. Methods Eighty patients with episodic cluster headache or chronic cluster headache, according to ICHD-3 beta criteria, were invited to participate. In this observational study, patients underwent a semi-structured interview where they were asked about the presence of 31 symptoms/signs in relation to a typical cluster headache attack. Symptoms included previously reported cluster headache pre-attack symptoms, premonitory migraine symptoms and accompanying symptoms of migraine and cluster headache. Results Pre-attack symptoms were reported by 83.3% of patients, with an average of 4.25 (SD 3.9) per patient. Local and painful symptoms, occurring with a median of 10 minutes before attack, were reported by 70%. Local and painless symptoms and signs, occurring with a median of 10 minutes before attack, were reported by 43.8% and general symptoms, occurring with a median of 20 minutes before attack, were reported by 62.5% of patients. Apart from a dull/aching sensation in the attack area being significantly ( p cluster headache. Since the origin of cluster headache attacks is still unresolved, studies of pre-attack symptoms could contribute to the understanding of cluster headache pathophysiology. Furthermore, identification and recognition of pre-attack symptoms could potentially allow earlier abortive treatment.

    Full Text Available AIM: The purpose of this study was to assess in a sample of female community cases the relationship between the increase of percentage of cervical signs and symptoms and the severity of temporomandibular disorders (TMD and vice-versa. MATERIAL AND METHODS: One hundred women (aged 18-26 years clinically diagnosed with TMD signs and symptoms and cervical spine disorders were randomly selected from a sample of college students. RESULTS: 43% of the volunteers demonstrated the same severity for TMD and cervical spine disorders (CSD. The increase in TMD signs and symptoms was accompanied by increase in CSD severity, except for pain during palpation of posterior temporal muscle, more frequently observed in the severe CSD group. However, increase in pain during cervical extension, sounds during cervical lateral flexion, and tenderness to palpation of upper fibers of trapezius and suboccipital muscles were observed in association with the progression of TMD severity. CONCLUSION: The increase in cervical symptomatology seems to accompany TMD severity; nonetheless, the inverse was not verified. Such results suggest that cervical spine signs and symptoms could be better recognized as perpetuating rather than predisposing factors for TMD.

    Chiari malformation is an alteration of the base of the skull with herniation through the foramen magnum of the brain stem and cerebellum. Although the most common presentation is occipital headache, the association of audio-vestibular symptoms is not rare. The aim of our study was to describe audio-vestibular signs and symptoms in Chiari malformation type i (CM-I). We performed a retrospective observational study of patients referred to our unit during the last 5 years. We also carried out a literature review of audio-vestibular signs and symptoms in this disease. There were 9 patients (2 males and 7 females), with an average age of 42.8 years. Five patients presented a Ménière-like syndrome; 2 cases, a recurrent vertigo with peripheral features; one patient showed a sudden hearing loss; and one case suffered a sensorineural hearing loss with early childhood onset. The most common audio-vestibular symptom indicated in the literature in patients with CM-I is unsteadiness (49%), followed by dizziness (18%), nystagmus (15%) and hearing loss (15%). Nystagmus is frequently horizontal (74%) or down-beating (18%). Other audio-vestibular signs and symptoms are tinnitus (11%), aural fullness (10%) and hyperacusis (1%). Occipital headache that increases with Valsalva manoeuvres and hand paresthesias are very suggestive symptoms. The appearance of audio-vestibular manifestations in CM-I makes it common to refer these patients to neurotologists. Unsteadiness, vertiginous syndromes and sensorineural hearing loss are frequent. Nystagmus, especially horizontal and down-beating, is not rare. It is important for neurotologists to familiarise themselves with CM-I symptoms to be able to consider it in differential diagnosis.

    The purpose of this study is to develop patient-reported (PRO) and observer-reported (ObsRO) outcome measures of ulcerative colitis (UC) signs/symptoms in children aged 5-17 with mild/moderate UC. The daily ulcerative colitis signs and symptoms scale (DUCS) was developed in two phases. Phase I involved concept elicitation interviews with patients and healthcare providers, review of website posts and item generation. Phase II involved cognitive debriefing and assessment of usability and feasibility of the eDiaries. Participants were recruited from five US clinical sites, a research recruitment agency, and internet advertising. Thematic and content analysis was performed to identify concepts from Phase I. The Phase II cognitive debriefing interviews were analyzed iteratively to identify problems with clarity and relevance of eDiary content. The US Food and Drug Administration (FDA) also reviewed and provided feedback on the eDiaries. Phase I included 32 participants (22 remission; 10 active disease). Phase II included 38 participants (22 remission; 16 active disease). A core set of seven signs and symptoms emerged that were reported by at least 30% of the patients interviewed: abdominal pain, blood in stool, frequent stools, diarrhea, stool urgency, nighttime stools, and tiredness. Participant input influenced changes such as refinement of item wording, revision of graphics, and selection of response scales. Revisions suggested by FDA included simplifying the response scale and adding questions to capture symptoms during sleeping hours. The findings of instrument development suggest that the DUCS PRO and ObsRO eDiaries are content-valid instruments for capturing the daily signs and symptoms of pediatric patients with mild to moderate UC in a clinical trial setting.

    Gijs Elshout

    Full Text Available CONTEXT: Febrile children in primary care have a low risk for serious infection. Although several alarming signs and symptoms are proposed to have predictive value for serious infections, most are based on research in secondary care. The frequency of alarming signs/symptoms has not been established in primary care; however, in this setting differences in occurrence may influence their predictive value for serious infections. OBJECTIVE: To determine the frequency of alarming signs/symptoms in febrile children in primary care. DESIGN: Observational cohort study. Clinical information was registered in a semi-structured way and manually recoded. SETTING: General practitioners' out-of-hours service. SUBJECTS: Face-to-face patient contacts concerning children (aged ≤16 years with fever were eligible for inclusion. MAIN OUTCOME MEASURES: Frequency of 18 alarming signs and symptoms as reported in the literature. RESULTS: A total of 10,476 patient contacts were included. The frequency of alarming signs/symptoms ranged from n = 1 (ABC instability; 40°C as reported by the parents; 12.9% to 8,647 contacts (parental concern; 82.5%. CONCLUSION: Although the prevalence of specific alarming signs/symptoms is low in primary care, ≥50% of children have one or more alarming signs/symptoms. There is a need to determine the predictive value of alarming signs/symptoms not only for serious infections in primary care, but as well for increased risk of a complicated course of the illness.

    Many peripheral intravenous catheter (PIVC) infusion phlebitis scales and definitions are used internationally, although no existing scale has demonstrated comprehensive reliability and validity. We examined inter-rater agreement between registered nurses on signs, symptoms and scales commonly used in phlebitis assessment. Seven PIVC-associated phlebitis signs/symptoms (pain, tenderness, swelling, erythema, palpable venous cord, purulent discharge and warmth) were observed daily by two raters (a research nurse and registered nurse). These data were modelled into phlebitis scores using 10 different tools. Proportions of agreement (e.g. positive, negative), observed and expected agreements, Cohen's kappa, the maximum achievable kappa, prevalence- and bias-adjusted kappa were calculated. Two hundred ten patients were recruited across three hospitals, with 247 sets of paired observations undertaken. The second rater was blinded to the first's findings. The Catney and Rittenberg scales were the most sensitive (phlebitis in >20% of observations), whereas the Curran, Lanbeck and Rickard scales were the most restrictive (≤2% phlebitis). Only tenderness and the Catney (one of pain, tenderness, erythema or palpable cord) and Rittenberg scales (one of erythema, swelling, tenderness or pain) had acceptable (more than two-thirds, 66.7%) levels of inter-rater agreement. Inter-rater agreement for phlebitis assessment signs/symptoms and scales is low. This likely contributes to the high degree of variability in phlebitis rates in literature. We recommend further research into assessment of infrequent signs/symptoms and the Catney or Rittenberg scales. New approaches to evaluating vein irritation that are valid, reliable and based on their ability to predict complications need exploration. © 2015 John Wiley & Sons, Ltd.

    Depression in the elderly is common and often resistant to treatment. It has been suggested that late-life depression may be related to underlying neurobiological changes. However, these observations are derived from diverse clinical samples and as yet have not been confirmed in a more representative population study. Our aim was to investigate associations between neurological signs as markers of underlying brain dysfunction and caseness for depression in an elderly community sample, controlling for physical health and comorbid/past neurological disorders. A cross-sectional analysis of 2102 older people without dementia from the ESPRIT project. Depressive symptomatology was ascertained using the CES-D and abnormal neurological signs/comorbidity from a full neurological examination according to ICD-10 criteria. Pyramidal, extrapyramidal, cranial nerve and sensory deficit signs were significantly associated with case-level depressive symptoms. However, all odds ratios were close to null values in participants who did not have previous neurological disorder. We confirmed previous findings of an association between neurological signs and case-level depressive symptoms in late life. However, this association may simply reflect the impact of more severe comorbid neurological disorder. (c) 2009 John Wiley & Sons, Ltd.

  15. Identifying signs and symptoms of intimate partner violence in an oncology setting.

    Domestic violence (DV), or intimate partner violence (IPV), is a prevailing problem in public health. Often, healthcare providers may be the first people that victims of DV will approach to reveal their problem or seek assistance. IPV is a pattern of control using assault and intimidating behaviors that has devastating effects on individuals, their families, and communities. Oncology nurses need to become familiar with common indicators of DV so that signs and symptoms of abuse can be identified when assessing patients in an oncology setting. Standards of oncology nursing practice support that the psychosocial impact of cancer on patients and their families or significant others needs to be considered at all stages of diagnosis and treatment. The psychosocial impact of other personal situations or concerns, such as IPV, can add to the complexity of cancer management. Routine screening for signs and symptoms of psychosocial distress helps identify patients who require additional interventions. Oncology nursing practice is based on a holistic approach to patient care, which supports that identification of physical and psychosocial needs are equally important. Oncology nursing provides many unique opportunities to help patients cope with cancer. Routine nursing assessment for signs and symptoms of abuse will provide an opportunity to assist patients with cancer to manage not only the life-threatening aspects of their diagnosis but also the life-threatening aspects of IPV.

  16. Root resorption: Focus on signs and symptoms of importance for avoiding root resorption during orthodontic treatment

    Full Text Available Introduction: This paper summarizes the different conditions, which have a well-known influence on the resorption of tooth roots, exemplified by trauma and orthodontic treatment. The concept of the paper is to summarize and explain symptoms and signs of importance for avoiding resorption during orthodontic treatment. The Hypothesis: The hypothesis in this paper is that three different tissue layers covering the root in the so-called periroot sheet can explain signs and symptoms of importance for avoiding root resorption during orthodontic treatment. These different tissue layers are; outermost - an ectodermal tissue layer (Malassez′s epithelium, a middle layer - composed by the collagen-mesodermal tissue layer, and an innermost root-close innervation layer. Abnormalities in one of these tissue layers are thought to cause inflammatory processes in the periodontal membrane comparable to inflammatory processes provoked by trauma and orthodontic pressure. Inflammatory reactions are followed by resorptive processes in the periroot sheet and along the root surface. Evaluation of the Hypothesis: Different morphologies in the dentition are signs of abnormal epithelium or an abnormal mesodermal layer. It has formerly been demonstrated how demyelinization of the myelin sheaths in the peripheral nerves close to the root provoke resorption. Accordingly, conditions affecting these tissue layers can be associated not only with different morphologies but also with general symptoms and diseases (e.g., ectodermal dysplasia and hypophosphatasia.

    Thirty-five patients suffering from schizophrenia, as diagnosed by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, were preselected from 7 clinical trials according to a priori criteria of catatonic signs and symptoms based on 3 Positive and Negative Syndrome Scale (PANSS) items: scores for PANSS item 19 (mannerism and posturing) and either item 4 (excitement) or item 21 (motor retardation) had to exceed or equal 4 at baseline. This particular patient population represents a severely psychotic sample: mean +/- SD PANSS total scores at baseline were 129.26 +/- 19.76. After I week of olanzapine treatment, mean PANSS total score was decreased significantly (-13.14; p < .001), as was mean PANSS total score after 6 weeks of olanzapine treatment (-45.16; p < .001); additionally, the positive subscale, negative subscale, and mood scores improved significantly. A significant improvement in the catatonic signs and symptoms composite score was also observed at week 6 (-4.96; p < .001). The mean +/- SD daily dose of olanzapine was 18.00 +/- 2.89 mg after 6 weeks of treatment. The present data analysis suggests the efficacy of olanzapine in the treatment of severely ill schizophrenic patients with nonspecified catatonic signs and symptoms.

    To assess the prevalence of signs and symptoms related to TMJ disorders in a group of young people with intelectual disability (ID) and a matched group of healthy adolescents. A group of 105 young Special Olympics (SO) athletes (ID group) aged from 14 to 25 years and a control group were examined for the presence or absence of signs and symptoms of TMD through interview and clinical examination. A total of 64 young people with ID (61%) had at least one sign of TMD compared to 41 (39%) of the individuals screened that was free of any TMD symptoms. A significantly higher prevalence of TMJ sounds (palpation and stethoscope), TMJ tenderness, maximum vertical opening, headaches were observed among SO athletes compared to the healthy control group (pdisabled patients and a possible cause of pain that should be examined more in detail. We suggest that oral screening in people with a mental disability should be modified by including basic TMJ examination parameters in order to allow better understanding of the pathological aspects so as to address effective preventive and therapeutic measures.

    Significant associations have been reported between (a) specific bacterial species isolated from root canals and (b) between individual bacterial species and endodontic symptoms and signs. The prime objective of this study was to determine whether particular combinations of specific bacteria are associated with individual endodontic symptoms and signs. Seventy root canals were investigated microbiologically taking care to maintain the viability of obligate anaerobes, which accounted for 64% of the total species isolated, including Peptostreptococcus micros, Prevotella melaninogenica, Prevotella oralis, Eubacterium aerofaciens, Eubacterium lentum, Fusobacterium nucleatum, Prevotella buccae and Prevotella intermedia. Significant associations were found between individual clinical features and the following pairs of species: (a) pain (37 cases) and Peptostreptococcus spp./Prevotella spp., Peptostreptococcus spp./Prevotella melaninogenica, Pstr. micros/Prev. melaninogenica (all P spp. (P spp./Eubacterium spp. (P spp./Eubacterium spp. (P < 0.05). Thus data from this investigation suggests that statistically significant associations exist between individual endodontic symptoms and signs and particular combinations of specific bacteria.

    This retrospective chart review was conducted to determine the presenting signs and symptoms of patients with primary brain tumors diagnosed in the emergency department. There were 101 patients (65 males and 36 females) identified with a hospital discharge diagnosis of primary brain tumor who were admitted through the emergency department. The presenting symptoms included headache (56 patients), altered mental status (51 patients), ataxia (41 patients), nausea or vomiting (37 patients), weakness (27 patients), speech deficits (21 patients), and sensory abnormalities (18 patients). The presenting signs included motor weakness (37 patients), ataxia (37 patients), papilledema (28 patients), cranial nerve palsies (26 patients), visual deficits (20 patients), and speech deficits (12 patients). The average age was 42.8 years, with a range of 3 days to 88 years. The majority of tumors were malignant astrocytomas. Tumor location was cortical in 68 patients, subcortical in 9 patients, and brainstem or cerebellum in 24 patients. In conclusion, patients of all ages may present to the emergency department with a variety of symptoms resulting from a primary brain tumor. Headache and altered mental status were common in our series of patients, but symptoms will depend on the size, location, and type of tumor. A complete neurologic examination is essential, including evaluation for papilledema.

    To study the frequency of cervical spine dysfunction (CCD) signs and symptoms in subjects with and without temporomandibular disorder (TMD) and to assess the craniocervical posture influence on TMD and CCD coexistence. Participants were 71 women (19 to 35 years), assessed about TMD presence; 34 constituted the TMD group (G1) and 37 comprised the group without TMD (G2). The CCD was evaluated through the Craniocervical Dysfunction Index and the Cervical Mobility Index. Subjects were also questioned about cervical pain. Craniocervical posture was assessed by cephalometric analysis. There was no difference in the craniocervical posture between groups. G2 presented more mild CCD frequency and less moderate and severe CCD frequency (p=0.01). G1 presented higher percentage of pain during movements (p=0.03) and pain during cervical muscles palpation (p=0.01) compared to G2. Most of the TMD patients (88.24%) related cervical pain with significant difference when compared to G2 (p=0.00). Craniocervical posture assessment showed no difference between groups, suggesting that postural alterations could be more related to the CCD. Presence of TMD resulted in higher frequency of cervical pain symptom. Thus the coexistence of CCD and TMD signs and symptoms appear to be more related to the common innervations of the trigeminocervical complex and hyperalgesia of the TMD patients than to craniocervical posture deviations.

  3. The genealogy of major depression: symptoms and signs of melancholia from 1880 to 1900.

    How deep are the historical roots of our concept of major depression (MD)? I showed previously that psychiatric textbooks published in 1900-1960 commonly described 18 characteristic depressive symptoms/signs that substantially but incompletely overlapped with the current DSM (Diagnostic and Statistical Manual of Mental Disorders) MD criteria. I here expand that inquiry to the key years of 1880-1900 during which our major diagnostic categories of manic-depressive illness (MDI) and dementia praecox were developed. I review the symptoms of depression/melancholia in 28 psychiatric textbooks and 8 other relevant documents from this period including monographs, reviews and the first portrayal of melancholia Kraepelin in 1883. Descriptions of melancholia in the late nineteenth and twentieth century textbooks closely resembled each other, both reporting a mean of 12.4 characteristic symptoms, and emphasizing core features of mood change and alterations in cognitive content and psychomotor behavior. The detailed monographs, reviews and the early description of Kraepelin were more thorough, reporting a mean of 16.6 of these characteristic symptoms. These nineteenth century texts often contained phenomenologically rich descriptions of changes in mood and cognition, loss of interest and anhedonia and emphasized several features not in DSM including changes in volition/motivation, posture/facial expression and derealization/depersonalization. In the early nineteenth century, melancholia was often defined primarily by delusions or as the initial phase of a unitary psychosis transitioning to mania and then dementia. By 1880, the concept of depression as an independent mood disorder with characteristic symptoms/signs and a good prognosis had stabilized. Kraepelin incorporated this syndrome into his diagnostic concept of MDI, changing its name to 'Depressive States', but did not alter its underlying nature or clinical description.

    Full Text Available OBJECTIVE: Evaluation of the clinical signs and symptoms predicting bacterial and viral pneumonia, in accordance with the Brazilian National Control Program for Acute Respiratory (ARI. METHODS: Observational prospective study. Seventy-six children from birth to six months of age who had pneumonia were studied in the emergency room. The patients were subdivided into two groups, based on radiological findings (gold-standard: 47 had bacterial pneumonia, and 29 had viral pneumonia. The frequencies, sensitivities, and specificities of the signs and symptoms were evaluated. RESULTS: The sensibilities and sensitivities of general findings in bacterial pneumonia were, respectively: fever 53.2%/40.0%; hypoactivity 68.4%/55.6% and prostration detected by the doctor 72.7%/55.0%. The same findings in viral pneumonias showed, respectively: 37.9%/40.0%, 66.7%/55.6% and 66.7%/55.6%. The sensibilities and sensitivities of respiratory findings in bacterial pneumonia were, respectively: coughing 66.0/38.1%, Respiratory rate = 50 ripm 76.6%/38.1%, altered respiratory auscultation 91.3%/10.5%, and chest indrawing 46.7%/80.0%. The same findings in viral pneumonias were, respectively: 69.0%/38.1%, 86.2%/38.1%, 85.7%/10.5% and 44.8%/80.0%. CONCLUSION: Analysis of signs and symptoms in each group did not distinguish bacterial from viral pneumonia. Our findings reinforce the adequacy of the ARI program in Brazil, which gives an early diagnosis of pneumonia, independent of its etiology.

    Solitary rectal ulcer syndrome (SRUS) is often resistant to medical and surgical treatment. This study assessed the effect of biofeedback in decreasing the symptoms and the healing of endoscopic signs in SRUS patients. Before starting the treatment, endoscopy and colorectal manometry was performed to evaluate dyssynergic defecation. Patients were followed every four weeks, and during each visit their response to treatment was evaluated regarding to manometry pattern. After at least 50% improvement in manometry parameters, recipients underwent rectosigmoidoscopy. Endoscopic response to biofeedback treatment and clinical symptoms were investigated. Duration of symptoms was 43.11±36.42 months in responder and 63.9 ± 45.74 months in non-responder group (P=0.22). There were more ulcers in non-responder group than responder group (1.50 ±0.71 versus 1.33±- 0.71 before and 1.30 ± 0.95 versus 0.67 ±0.50 after biofeedback), although the difference was not significant (P=0.604, 0.10 respectively). The most prevalent symptoms were constipation (79%), rectal bleeding (68%) and anorectal pain (53%). The most notable improvement in symptoms after biofeedback occured in abdominal pain and incomplete evacuation, and the least was seen in mucosal discharge and toilet waiting as shown in the bar chart. Endoscopic cure was observed in 4 of 10 patients of the non-responder group while 8 patients in responder group experienced endoscopic improvement. It seems that biofeedback has significant effect for pathophysiologic symptoms such as incomplete evacuation and obstructive defecation. Improvement of clinical symptoms does not mean endoscopic cure; so to demonstrate remission the patients have to go under rectosigmoidoscopy.

    The aims of this study was to compare the diagnostic accuracy of Conventional Radiography (CR). Radionuclide Angiography (RNA). Planar Scintigraphy (PS) and Single Photon Emission Computed Tomography (SPECT) for the evaluation of temporomandibular joint (TMJ) disorder; and to show whether technetium-99m-MDP uptake on quantitative SPECT correlated with the symptom and/or signs. Three Phase Bone Scintigraphy (TPBS) and SPECT of both TMJ were performed in 51 patients (M : F = 10 : 41 mean age= 30.4 :28.6, respectively) with unilateral TMJ disorder after an intravenous injection of 25 mCi (925 MBq) of 99mTc-MDP. Data were analyzed by creating three regions of interest (ROIs) over designated areas both on the PS and SPECT: Lesion (L). Non-lesion(NL) which is contralateral to L and Background (BG). L/ NL and L/BG (=[(L-BG)/500,000] x 100 (%)] ratios were calculated for each patients. L/NL ratios on SPECT were compared according to the symptom/signs or not. There was a fair correlation of L/N values between three slice-and seven slice-added SPECT images (r=0.5124, p=0.006, y=0.5588 + 0.5414X). The percentages of symptoms or signs were: pain (76.5%), mouth opening limitation (49.0%), joint sound (39.2%), discomfort (43.1%), headache(27.5%), neck stiffness (21.6%), closed lock (5.9%) / tenderness (47.1%), joint click (54.9%) and limitation of maximum mouth opening (45.1%). The Sensitive of SPECT(86.3%) was better than PS(66.7%), RNA(27.5%), and CR(26.3%). According to the presence of symptom/sign or not, comparative analysis of L/NL ratios on SPECT showed a fair correlation in pain (1.16 : 1.11) mouth opening limitation (1.21 : 1.09), joint sound (1.19 : 1.08), discomfort (1.22 : 1.09), headache (1.19: 1.13), tenderness (1.16 : 1.14) and limitation of maximum mouth opening (1.16 : 1.13), but little correlation in neck stiffness (1.12 : 1.15), closed lock (1.06 : 1.15), dislocation (1.08 : 1.15) joint click (1.12 : 1.18). In conclusion, quantitative SPECT is the noninvasive

    The aim of this study was to investigate oral symptoms and clinical parameters in dry eye patients. Subjective reports of the sensation of a dry mouth, salivary flow rates, and clinical parameters of oral disease related to three different types of dry eye patients were examined. There were 224 individuals, including dry eye patients and control subjects. The dry eye patients were classified into three types: patients with Sjögren's syndrome (SS-DE), patients without SS-DE (non-SS-DE), and patients with Stevens-Johnson syndrome (SJS-DE). Salivary flow rates were measured using two kinds of sialometry. Subjective and objective oral symptoms and signs were also examined. Over half of the dry eye patients complained of a dry mouth. The flow rates of their stimulated whole saliva and parotid saliva were significantly lower than those of the control groups (P Candida frequently occurred in dry eye patients.

    Labial mucosa transplantation for the treatment of canine keratoconjunctivitis sicca (KCS) has been reported recently. Postoperative alleviation of clinical signs was noted and assumed to be the result of labial salivary glands providing lubrication to the ocular tissue. The aim of this study was to evaluate the presence of minor salivary glands (MSG) in the canine oral mucosa. Oral mucosal biopsies were collected from six dogs that died (n = 1) or were euthanized (n = 5) for reasons unrelated to this study. The breeds included were two Doberman Pinschers, one Labrador Retriever, one Portuguese Water Dog, one German Shepherd Dog, and one mixed canine. Three were spayed females, and three were castrated males with the median age of 9 years (range, 6-13 years). Samples were obtained by an 8-mm punch biopsy at the following locations of the canine oral cavity: upper rostral labial mucosa at midline, lower rostral labial mucosa at midline, upper labial mucosa near the commissure, lower labial mucosa near the commissure, and buccal mucosa approximately 1 cm caudal to the commissure. Samples were routinely processed with hematoxylin and eosin, and periodic acid-Schiff stains. Samples were evaluated by light microscopy. At the selected locations, no MSG or other secreting cells were detected. Minor salivary glands are not associated with alleviation of canine KCS symptoms following labial mucosa transplantation. Further studies are needed to determine the mechanism leading to the transient improvement of KCS symptoms in canine patients following labial mucosa transplantation. © 2017 American College of Veterinary Ophthalmologists.

    INTRODUCTION Chronic excess growth hormone production results in acromegaly, a condition associated with widespread physical changes, including soft tissue and bony overgrowth. When untreated, acromegaly reduces life expectancy. Patients usually remain undiagnosed for years after the onset of symptoms, by which stage irreversible physical changes have often occurred. METHOD A cross-sectional questionnaire study involving patients with acromegaly from the Waikato Endocrine Unit and the New Zealand Acromegaly Society evaluated features of acromegaly that were present before diagnosis. The aim of this study was to identify acromegaly features that were most prevalent to promote increased awareness about the disease by healthcare providers. RESULTS 81 participants were included. The main pre-diagnosis physical changes participants reported were acral changes, alterations in facial features and oral symptoms. For some, these features were present for more than 10 years before the acromegaly diagnosis. Multiple co-morbidities associated with acromegaly were reported. Two-thirds of the participants felt that an earlier diagnosis was possible. Most participants were in contact with General Practitioners (GPs) and/or dentists before diagnosis. Endocrinologists had the highest diagnosis rate, followed by GPs. Dentists had a low diagnosis rate despite a high prevalence of oral symptoms among study participants. CONCLUSION Increased awareness of acromegaly among primary care clinicians is important as they are the first-point-of-contact with the healthcare system for most patients. Health professionals' early recognition of symptoms and signs of acromegaly would reduce delays in time-to-diagnosis, enable earlier treatment and may improve outcomes for patients with acromegaly.

    The absence of classical symptoms and signs of hyperthyroidism often results in delayed diagnosis and treatment. The objective of the study was to determine the prevalence of symptoms and signs of hyperthyroidism according to patients' age and gender as well as severity and type of hyperthyroidism. This was a cross-sectional study of 3049 consecutive patients with hyperthyroidism presenting to a single secondary/tertiary care clinic. Calculation of adjusted odds ratios for presence/absence of symptoms/signs of hyperthyroidism simultaneously analyzing the influence of patients' age/gender, disease etiology/severity, symptom duration, and smoking. The majority of patients older than 61 yr had two or more symptoms. The lowest proportion of subjects reporting five or more symptoms was found in those older than 61 yr. Increasing age was associated with reduced adjusted odds ratio for the presence of most classical symptoms except for weight loss and shortness of breath, independent of disease severity. Those with more severe hyperthyroidism and smokers had increased odds ratios for most symptoms. Older age, higher serum free T(4) concentrations at diagnosis, male gender, and toxic nodular hyperthyroidism were independently associated with risk of atrial fibrillation. Signs of ophthalmopathy were associated with increasing age, smoking, longer symptom duration, and female gender. Classical symptoms and signs of hyperthyroidism are significantly less prevalent in older patients and more prevalent in smokers and subjects with higher free T(4) concentrations. We propose a lower threshold for performing thyroid function tests in patients older than 60 yr, especially in those presenting with atrial fibrillation, weight loss, or shortness of breath.

    Clinical Decision Support Systems (CDSS) help to improve health care and reduce costs. However, the lack of knowledge management and modelling hampers their maintenance and reuse. Current EHR standards and terminologies can allow the semantic representation of the data and knowledge of CDSS systems boosting their interoperability, reuse and maintenance. This paper presents the modelling process of respiratory conditions' symptoms and signs by a multidisciplinary team of clinicians and information architects with the help of openEHR, SNOMED and clinical information modelling tools for a CDSS. The information model of the CDSS was defined by means of an archetype and the knowledge model was implemented by means of an SNOMED-CT based ontology.

    Lack of self-monitoring of blood glucose (SMBG) records in actual practice settings continues to create therapeutic challenges for clinicians, especially in adjusting insulin therapy. In order to overcome this clinical obstacle, a "Symptom-based Insulin adjustment for Glucose Normalization" (SIGN) algorithm was developed to guide clinicians in caring for patients with uncontrolled type 2 diabetes who have few to no SMBG records. This study examined the clinical outcome and safety of the SIGN algorithm. Glycated hemoglobin (HbA1c), insulin usage, and insulin-related adverse effects of a total of 114 patients with uncontrolled type 2 diabetes who refused to use SMBG or performed SMBG once a day for less than three times per week were studied 3 months prior to the implementation of the algorithm and prospectively at every 3-month interval for a total of 6 months after the algorithm implementation. Patients with type 1 diabetes, nonadherence to diabetes medications, or who were not on insulin therapy at any time during the study period were excluded from this study. Mean HbA1c improved by 0.29% at 3 months (P = 0.015) and 0.41% at 6 months (P = 0.006) after algorithm implementation. A slight increase in HbA1c was observed when the algorithm was not implemented. There were no major hypoglycemic episodes. The number of minor hypoglycemic episodes was minimal with the majority of the cases due to irregular meal habits. The SIGN algorithm appeared to offer a viable and safe approach when managing uncontrolled patients with type 2 diabetes who have few to no SMBG records.

    Silodosin is an α-adrenoceptor antagonist with high selectivity for α(1A)- relative to α(1B)- adrenoceptors. In men aged >50 years with benign prostatic hyperplasia (BPH), silodosin 8 mg once daily, compared with placebo, was associated with a significantly more rapid and effective improvement in the total International Prostate Symptom Score (IPSS) and the storage and voiding IPSS subscores in three 12-week, phase III trials conducted in Europe and the US. In the European trial, silodosin was at least as effective as tamsulosin 0.4 mg once daily in improving the total IPSS. Silodosin was significantly more effective than placebo (all three phase III trials) and tamsulosin (European phase III trial) in simultaneously improving nocturia, frequency and incomplete emptying, according to a post hoc analysis. Long-term, open-label extension trials demonstrated that silodosin provided sustained relief of the signs and symptoms of BPH for up to 1 year. Silodosin was generally well tolerated, and was associated with minimal cardiovascular adverse effects. Abnormal ejaculation, a class effect of α(1A)-adrenoceptor antagonists, was the most common silodosin-associated adverse reaction, but resulted in treatment withdrawal of only a limited number of patients. © 2011 Adis Data Information BV.

    Andre Gide wrote, "Everything has been said before, but since nobody listens we have to keep going back and beginning all over again." To a certain extent, that statement applies to the importance of accurate and systematic history taking and physical examination in clinical practice. Although we are trained in habits of comprehension and accuracy in history taking and examination of patients, periodic reminders are required to develop a diagnostic framework based on observation (inspection), palpation, percussion, and auscultation. This monograph reemphasizes the method to be pursued in the treatment of a patient with pulmonary symptoms. It consists of three parts: (1) questioning the patient about his or her medical history; (2) performing the physical examination of the respiratory system; and (3) examining the extrapulmonary signs and symptoms. Once a strong clinical framework has been constructed, its further development and refinement depend on the clinician's experience, power of observation, and systematic reading of the medical literature. Good physicians must continue to learn throughout their careers; this is the most essential element of a physician's development. Be patient, however; as Cowper said, "Knowledge, to become wisdom, needs experience."

    The purpose of this study is to highlight the evidence of signs and symptoms of craniomandibular disorders (CMD) in patients suffering from fibromyalgia. The study has been carried out from May 2011 to May 2015, recruiting a sample of fibromyalgia patients at the Department of Neurophysiopathology at the hospital Policlinico in Bari. Among the 150 examined patients, 60 of them have been diagnosed to suffer from fibromyalgia and 27 accepted to be investigated with a gnathologic examination at the Dental School at the University of Bari. 24 patients (88.9%) were women and 3 (11.1%) men; from 26 to 66 years old (average age, 39). 14 patients (51.9%) were affected by primary fibromyalgia, the remaining 13 (48.1%) by secondary fibromyalgia, mainly associated with hypothyroidism (29.6%). VAS average score was about 8 ± 1.85. The frequency of pain was daily in 15 patients (55.6%); twice a week in 10 patients (37.03%) and a few times a month in 2 patients (7.4%). 11 patients (40.7%) attributed the onset of fibromyalgia to a specific instigating event. In addition, from the gnathologic anamnesis, 11 patients (40,7%) reported a painful symptom in the head-neck region, especially in the frontal region, in the neck, in the masseter muscle and ATM. VAS average score was 3.4 ± 2.8, significantly lower than the one referring to the fibromyalgia pain. The gnathological examination found CMD signs and symptoms in 18 patients (66.7%). Concerning the prevalence of CMD, in type I fibromyalgia, myofascial pain was more frequent (5 patients), whereas in type II fibromyalgia, what was more frequent was a dislocation with reduction (3 patients). Based on clinic experience, we can affirm that some patients with CMD report pain in other regions. It is difficult to distinguish the CMD forms directly correlated to fibromyalgia from those engendered by parafunctional activities; hence the need is to resolve the fibromyalgia syndrome adopting a multidisciplinary approach.

    The majority of deaths from cancer occur in low and middle income countries, partly due to poor public awareness of the signs and symptoms of cancer. A community based survey using the Cancer Awareness Measure (CAM) questionnaire was conducted in three different communities in Oman. Omani adults aged 18 years and above were invited to participate in the study. A total of 345 responded from 450 invited participants (response rate=76.7%). The majority of respondents were unable to identify the common signs and symptoms of cancer identified in the CAM (average awareness was 40.6%). The most emotional barrier to seeking help was worry about what the doctor might find (223, 64.6%); a practical barrier was too busy to make an appointment (259, 75.1%) and a service barrier was difficulty talking to the doctor (159, 46.1%). The majority of respondents (more than 60% for seven out of ten symptoms) would seek medical help in two weeks for most signs or symptoms of cancer. Females were significantly more likely than males to be embarrassed (pawareness of the signs and symptoms of cancer in Oman. This might leads to earlier diagnosis, improved prognosis and reduced mortality from cancer.

    The aim was to identify the main signs and symptoms of cardiac patients hospitalized in a unit of intensive cardiology care in order to infer the main nursing diagnoses (NDs). We performed a cross-sectional study; the sample consisted of 77 randomly selected records. Those records included only patients hospitalized for cardiovascular causes and with electronic chart available. Signs and symptoms identified at admission were psychic (40.3%), compressive dressing on arterial puncture site (33.8%), chest pain (29.9%), tachycardia (22.1%), and hemodynamic instability (20.8%). According to the data collected, we were able to infer that acute pain, excess of fluid volume, decreased cardiac output, spontaneous ventilation impaired, anxiety and impaired skin integrity are priority for the NDs in the studied population.

    In a study comprising 100 patients referred to a surgical clinic with symptons suggestive of gastro-oesophageal reflux disease, the value of different diagnostic procedures was investigated. Positive acid perfusion and 24-h pH tests were the commonest findings. Forty-nine per cent showed normal oesophageal mucosa or diffuse oesophagitis at endoscopy. The severity of heartburn and regurgitation did not differ between patients with normal oesophageal mucosa and oesophagitis of various severities. The severity of macroscopic oesophagitis was significantly corelated to the total reflux time, the presence of reflux or a hiatal hernia at radiology, an open cardia or reflux at endoscopy, pressure transmission or reflux, and low lower oesophageal sphincter pressure at manometry. Gastric hypersecretion was found in 66% of the patients. Gastric acid secretion was not correlated to the severity of oesophagitis or to the findings at 24-h pH test. In patients with severe oesophagitis the sensivity for radiologic, manometric and endoscopic signs of incompetence of the gastro-oesophageal junction was 94%.

    [Purpose] To assess the association between the oclusal characteristics, headache, parafunctional habits and clicking sounds and signs/symptoms of TMD in adolescents. [Subjects] Adolescents between 14 and 18 years of age. [Methods] The participants were evaluated using the Helkimo Index and a clinical examination to track clicking sounds, parafunctional habits and other signs/symptoms of temporomandibular disorder (TMD). Subjects were classified according to the presence or absence of headache, type of occlusion, facial pattern and type of bite. In statistical analyse we used the chi-square test and Fisher's exact test, with a level of significance of 5%. [Results] The sample was made up of 81 adolescents with a mean age of 15.64 years; 51.9% were male. The prevalence of signals/symptoms of TMD was 74.1%, predominantly affecting females. Signals/symptoms of TMD were significantly associated with clicking sounds, headache and nail biting. No associations were found between signals/symptoms of TMD and angle classification, type of bite and facial pattern. [Conclusion] Headache is one of the most closely associated symptoms of TMD. Clicking sounds were found in the majority of cases. Therefore, the sum of two or more factors may be necessary for the onset and perpetuation of TMD.

    Nondystrophic myotonias (NDMs) are rare diseases caused by mutations in skeletal muscle ion channels. Patients experience delayed muscle relaxation causing functionally limiting stiffness and pain. Mexiletine-induced sodium channel blockade reduced myotonia in small studies; however, as is common in rare diseases, larger studies of safety and efficacy have not previously been considered feasible. To determine the effects of mexiletine for symptoms and signs of myotonia in patients with NDMs. A randomized, double-blind, placebo-controlled 2-period crossover study at 7 neuromuscular referral centers in 4 countries of 59 patients with NDMs conducted between December 23, 2008, and March 30, 2011, as part of the National Institutes of Health-funded Rare Disease Clinical Research Network. Oral 200-mg mexiletine or placebo capsules 3 times daily for 4 weeks, followed by the opposite intervention for 4 weeks, with 1-week washout in between. Patient-reported severity score of stiffness recorded on an interactive voice response (IVR) diary (scale of 1 = minimal to 9 = worst ever experienced). Secondary end points included IVR-reported changes in pain, weakness, and tiredness; clinical myotonia assessment; quantitative measure of handgrip myotonia; and Individualized Neuromuscular Quality of Life summary quality of life score (INQOL-QOL, percentage of maximal detrimental impact). Mexiletine significantly improved patient-reported severity score stiffness on the IVR diary. Because of a statistically significant interaction between treatment and period for this outcome, primary end point is presented by period (period 1 means were 2.53 for mexiletine and 4.21 for placebo; difference, -1.68; 95% CI, -2.66 to -0.706; P < .001; period 2 means were 1.60 for mexiletine and 5.27 for placebo; difference, -3.68; 95% CI, -3.85 to -0.139; P = .04). Mexiletine improved the INQOL-QOL score (mexiletine, 14.0 vs placebo, 16.7; difference, -2.69; 95% CI, -4.07 to -1.30; P < .001) and

    The relationship of the frequency of temple headache to signs and symptoms of temporomandibular joint (TMJ) disorders (TMD) was investigated in a subset of a larger convenience sample of community TMD cases. The study sample included 86 painful TMD, nonheadache subjects; 309 painful TMD subjects with varied frequency of temple headaches; and 149 subjects without painful TMD or headache for descriptive comparison. Painful TMD included Research Diagnostic Criteria for Temporomandibular Disorders diagnoses of myofascial pain, TMJ arthralgia, and TMJ osteoarthritis. Mild to moderate-intensity temple headaches were classified by frequency using criteria based on the International Classification of Headache Disorder, 2nd edition, classification of tension-type headache. Outcomes included TMD signs and symptoms (pain duration, pain intensity, number of painful masticatory sites on palpation, mandibular range of motion), pressure pain thresholds, and temple headache resulting from masticatory provocation tests. Trend analyses across the painful TMD groups showed a substantial trend for aggravation of all of the TMD signs and symptoms associated with increased frequency of the temple headaches. In addition, increased headache frequency showed significant trends associated with reduced PPTs and reported temple headache with masticatory provocation tests. In conclusion, these findings suggest that these headaches may be TMD related, as well as suggesting a possible role for peripheral and central sensitization in TMD patients.

    To assess dry eye treatment with four preservative-free dry eye artificial tear treatments to facilitate evidence-based prescribing. A randomised, single masked crossover trial of Clinitas Soothe, Hyabak, Tears Again and TheraTears artificial tears was conducted on 50 symptomatic dry eye patients, aged 60.8±14.2years. At baseline and after trialling each treatment for 4 weeks, signs and symptoms were assessed using the Ocular Surface Disease Index (OSDI), non-invasive tear break-up time, fluorescein tear break-up time, tear meniscus height (TMH), Phenol Red test, lid-parallel conjunctival folds (LIPCOF), ocular surface staining, and lipid layer grading and osmolarity (baseline visit only). OSDI (p=0.002), LIPCOF (p=0.014) and conjunctival staining (pdry eye treatment on ocular symptoms and signs was similar. Clinitas Soothe and Hyabak were preferred by 34%/30% of participants, but only subjective comparison with the other drops influenced this choice. TheraTears was preferred (by 24%) by those with a lower baseline tear volume (p=0.01) and Tears Again (by 12%) by those with a thinner baseline lipid layer (p=0.04). The treatment that afforded the greatest improvement in clinical signs did not consistently match each individual's preferred treatment. If prescribed to a general dry eye population, the artificial tears performed similarly, improving symptoms and conjunctival signs. However, osmolarity balanced artificial tears were the preferred treatment in individuals with low baseline tear volume and lipisomal spray for individuals with a baseline lipid layer deficiency.

    Context Non-dystrophic myotonias (NDM) are rare diseases caused by mutations in skeletal muscle ion channels. Patients experience delayed muscle relaxation causing functionally-limiting stiffness and pain. Mexiletine-induced sodium channel blockade reduced myotonia in case studies and one single blind trial. As is common in rare diseases, larger studies of safety and efficacy have not previously been considered feasible. Objective To determine the effects of mexiletine for symptoms and signs of myotonia in NDM. Design, Setting, and Participation Fifty-nine patients with NDM participated in a randomized, double-blind, placebo-controlled two-period crossover study conducted between December 23, 2008 and March 30, 2011 at 7 neuromuscular referral centers in 4 countries, as part of the NIH-funded Rare Disease Clinical Research Network. Intervention Oral 200 mg mexiletine or placebo capsules three times daily for 4 weeks, followed by the opposite intervention for 4 weeks, with 1 week wash-out between periods. Main Outcome Measures Patient-reported stiffness recorded on an interactive voice response diary (IVR) was the primary endpoint (1 ‘minimal’ to 9 ‘worst ever experienced’). Secondary endpoints included IVR-reported changes in pain, weakness, and tiredness, clinical myotonia assessment, quantitative grip myotonia, Individualized Neuromuscular Quality of Life (INQoL, percent of maximal detrimental impact), SF-36, electrophysiological exercise testing, and needle EMG. Results Mexiletine significantly improved patient-reported stiffness on the IVR. Because of a statistically significant interaction between treatment and period for this outcome, primary endpoint is presented by period (period 1 means were mexiletine 2.53 versus placebo 4.21, difference −1.68, 95% Confidence Interval [CI] −2.66, −0.706, P<0.001; period 2 means were mexiletine 1.60 versus placebo 5.27, difference −3.68, 95% CI −3.85, −0.139, P=0.04). Mexiletine improved the INQoL QOL

    To search for signs and symptoms before serious infection (SI) occurs in tocilizumab (TCZ)-treated rheumatoid arthritis (RA) patients. Individual case safety reports, including structured (age, sex, adverse event [AE]) and unstructured (clinical narratives) data, were analyzed by automated text mining from a Japanese post-marketing AE-reporting database (16 April 2008-10 April 2015) assuming the following: treated in Japan; TCZ RA treatment; ≥1 SI; unable to exclude causality between TCZ and SIs. The database included 7653 RA patients; 1221 reports met four criteria, encompassing 1591 SIs. Frequent SIs were pneumonia (15.9%), cellulitis (9.9%), and sepsis (5.0%). Reports for 782 patients included SI onset date; 60.7% of patients had signs/symptoms ≤28 days before SI diagnosis, 32.7% had signs/symptoms with date unidentified, 1.7% were asymptomatic, and 4.9% had unknown signs/symptoms. The most frequent signs/symptoms were for skin (swelling and pain) and respiratory (cough and pyrexia) infections. Among 68 patients who had normal laboratory results for C-reactive protein, body temperature, and white blood cell count, 94.1% had signs or symptoms of infection. This study identified prodromal signs and symptoms of SIs in RA patients receiving TCZ. Data mining clinical narratives from post-marketing AE databases may be beneficial in characterizing SIs.

    Full Text Available We aimed to assess the efficacy of Centella asiatica for improvement of the signs and symptoms of chronic venous insufficiency (CVI. We searched 13 electronic databases including the Cochrane Central Register of Controlled Trials for randomised controlled trials assessing the efficacy of Centella asiatica for CVI. Two review authors independently selected studies, assessed the risks of bias of included studies and extracted data. The treatment effects of similar studies were pooled whenever appropriate. Eight studies met the inclusion criteria. The pooling of data of similar studies showed that Centella asiatica significantly improved microcirculatory parameters such as transcutaneous partial pressure of CO2 and O2, rate of ankle swelling and venoarteriolar response. Three out of the eight studies did not provide quantitative data. However, these studies reported that patients treated with Centella asiatica showed significant improvement in CVI signs such as leg heaviness, pain and oedema. Our results show that Centella asiatica may be beneficial for improving signs and symptoms of CVI but this conclusion needs to be interpreted with caution as most of the studies were characterised by inadequate reporting and thus had unclear risks of bias, which may threaten the validity of the conclusions.

    Assessment of disease severity for patients with hyperthyroidism involves clinical evaluation and laboratory testing. To determine if there is a correlation between symptoms and thyroid function test results, we prospectively studied hyperthyroid patients using a standardized symptom rating scale and serum thyroid function parameters. We examined 25 patients with untreated, newly diagnosed Graves' disease using the Hyperthyroid Symptom Scale (HSS) and serum levels of thyroxine (T4), triiodothyronine (T3) relative insulin area (RIA), and estimates of free thyroxine index (FTI). In addition, we compared thyroid hormone levels with standard measures of depression and anxiety in these patients. When regression analyses controlling for age were performed, none of these symptom ratings were associated with FTI or T3 RIA. The HSS was correlated with goiter size and anxiety ratings and was inversely correlated with age. The present study suggests that there is no relationship between the clinical assessment of disease severity and serum levels of thyroid hormone in untreated Graves' disease.

    This study measured the impact of previous contact lens wearing schedule on the resolution of signs and contact lens-related symptoms among wearers of lotrafilcon A lenses. One hundred forty adapted low Dk daily wear (DW) and 140 adapted low Dk extended wear (EW) subjects were enrolled and examined for 1 year (overall study length is 3 years). All subjects wore lotrafilcon A lenses on a wearing schedule of up to 30 nights continuous wear with monthly replacement of lenses. Examinations were conducted at 1 week, 1, 6, and 12 months. The former EW wearers presented at baseline with significantly higher conjunctival staining and epithelial microcysts (p Dk DW and EW wearers within 1 week as did severity of dryness during the day for the former DW wearers, in part as a result of their higher prevalence at baseline in the DW group. Subjects reported redness improved significantly by the 1-month visit. Continuous wear of high Dk silicone hydrogel lenses resulted in an improvement in ocular redness and neovascularization and dryness symptoms among subjects in this trial, regardless of their previous low Dk lens-wearing schedule. All improvements in signs and symptoms were sustained through 12 months.

    Up to half of all people with HIV infection have some degree of cognitive impairment. This impairment is typically mild, but nonetheless often disabling. Although early detection of cognitive impairment offers the greatest hope of effective intervention, there are important barriers to this goal in most clinical settings. These include uncertainty about how self-reported cognitive symptoms relate to objective impairments, and the paucity of bedside measurement tools suitable for mild deficits. Clinicians need guidance in interpreting cognitive symptoms in this population, and a brief cognitive measurement tool targeted to mild impairment. We addressed these two problems together here. The objective of this study was to determine the extent to which performance on cognitive tests and self-reported cognitive symptoms form a unidimensional construct. Two hundred three HIV+ individuals completed the Montreal Cognitive Assessment, computerized cognitive tasks and a questionnaire eliciting cognitive symptoms. Rasch measurement theory was applied to determine whether patient-reported and performance items could be combined to measure cognition as a unidimensional latent construct. Performance-based items and cognitive symptoms are arranged hierarchically along the same continuum of cognitive ability, forming a measure with thresholds covering a broad spectrum of ability that has good internal reliability. The cognitive symptoms that fit the measurement model relate to important aspects of everyday life, providing evidence that the identified construct is meaningful. This finding lays the foundation for a rapid measure of cognitive ability in people with HIV infection that is feasible for routine clinical use, and shows that some cognitive symptoms are systematically related to performance in this population.

    Full Text Available OBJECTIVE: The aim of this study was to evaluate the occurrence of the well-known predisposing factors and signs and symptoms usually associated with either overreaching or overtraining syndrome in physical fitness centers in São Paulo City, Brazil. METHOD: A questionnaire consisting of 13 question groups pertaining to either predisposing factors (1-7 or signs and symptoms (8-13 was given to 413 subjects. The general training schedule of the volunteers was characterized by workout sessions of 2.18 ± 0.04 h for a total of 11.0 ± 0.3 h/week for 33 ± 2 months independent of the type of exercise performed (walking, running, spinning, bodybuilding and stretching. A mean score was calculated ranging from 1 (completely absent to 5 (severe for each question group. A low occurrence was considered to be a question group score lower than 4, which was observed in all 13 question groups. RESULTS: The psychological evaluation by POMS Mood State Questionnaire indicated a normal non-inverted iceberg. The hematological parameters, creatine kinase activity, cortisol, total testosterone and free testosterone concentrations were within the normal ranges for the majority of the volunteers selected for this analysis (n = 60. CONCLUSION: According to the questionnaire score analysis, no predisposing factors or signs and symptoms usually associated with either overreaching or overtraining were detected among the members of physical fitness centers in São Paulo City, Brazil. This observation was corroborated by the absence of any significant hematological or stress hormone level alterations in blood analyses of the majority of the selected volunteers (n = 60.

    The use of chewing-gum and piercing has become common among adolescents and might result in increased oral muscle activity and overloading. Aim To investigate the frequency of oral piercing and parafunctions in relation to symptoms of temporomandibular disorders (TMD) among adolescents. One hundred and twenty-four third level high school students, living either in a city or in a small town, enrolled in either science or media programmes, were included. The students completed a questionnaire regarding different parafunctions and symptoms of TMD. A clinical examination of the temporomandibular system and estimation of the tooth wear was performed in 116 students. Chewing-gum was used by 86% of the students (25% with a daily use) and 14% had an oral piercing. The science students used more chewing gum than the media students (p = 0.008), while the media students had more piercings (p headache, 18% for clicking, 7% for facial pain and 6% for difficulty to open wide. Girls reported more headaches (p = 0.007) and more severe symptoms (p = 0.003), had more medical consultations and used more analgesics (both p headache (p temporomandibular joints and muscles (both p headache and muscle tenderness (both p headache (p < 0.05) and tooth wear (p = 0.004). There is an association between use of chewing gum, nail biting, oral piercing, and symptoms of TMD.

    To investigate changes in signs, symptoms, and tear cytokines following punctal plug occlusion in patients with dry eye. A single-center study was conducted at Singapore Eye Research Institute. Nonabsorbable punctal plugs were inserted in the lower punctum of both eyes in patients with moderate dry eye. Over 3 weeks, in the more severe eye, dry eye symptoms, fluorescein corneal staining, Schirmer I (without topical anesthesia) test, tear film breakup time (TFBUT), and safety were assessed. Cytokine and matrix metalloproteinase-9 (MMP-9) levels in tear samples were measured. Twenty-nine patients (mean age 49.8 years) with moderate dry eye were evaluated. At baseline, mean (standard deviation) global symptoms score was 53.8 (26.5), Schirmer I test score was 5.1 (2.8) mm, and TFBUT was 2.2 (0.6) seconds. After 3 weeks, punctal occlusion significantly reduced global irritation symptoms score (Pdry eye disease. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

    Usher syndrome types I and II are clinical syndromes with substantial genetic and clinical heterogeneity. We undertook the current study in order to identify ocular symptoms and signs that could differentiate between the two types. Sixty-seven patients with Usher syndrome were evaluated. Based on audiologic and vestibular findings, patients were classified as either Usher type I or II. The severity of the ocular signs and symptoms present in each type were compared. Visual acuity, visual field area, electroretinographic amplitude, incidence of cataract and macular lesions were not significantly different between Usher types I and II. However, the ages when night blindness was perceived and retinitis pigmentosa was diagnosed differed significantly between the two types. There seems to be some overlap between types I and II of Usher syndrome in regard to the ophthalmologic findings. However, night blindness appears earlier in Usher type I (although the difference in age of appearance appears to be less dramatic than previously assumed). Molecular elucidation of Usher syndrome may serve as a key to understanding these differences and, perhaps, provide a better tool for use in clinical diagnosis, prognosis and genetic counseling.

    Full Text Available Abstract Background Lung cancer is the leading cause of cancer death in Australia. There is potential that health promotion about the risks and warning signs of lung cancer could be used to reduce delays in symptom presentation when symptoms are first detected. This study investigated knowledge, attitudes and beliefs which might impact help-seeking behaviour and could provide insight into possible public health interventions in New South Wales (NSW. Methods A convergent mixed method study design was used wherein data from 16 qualitative focus groups of residents (40+ years, purposefully recruited and stratified by smoking status, age and geography (metropolitan/regional, were compared with a CATI administered population-wide telephone survey (n = 1,000 using the Cancer Research UK cancer awareness measure (LungCAM. Qualitative findings were analysed thematically using NVIVO. Logistic regression analysis was used to investigate predictors of symptom knowledge in STATA. Findings were integrated using triangulation techniques. Results Across focus groups, haemoptysis was the only symptom creating a sense of medical urgency. Life experiences evoked a ‘wait and see’ attitude to any health deterioration. Perceived risk was low amongst those at risk with current smokers preferring to deny their risk while former smokers were generally unaware of any ongoing risk. The quantitative sample consisted of females (62 %, 40–65 years (53 %, low SES (53 %, former (46 % and current smokers (14 %. In quantitative findings, haemoptysis and dyspnoea were the most recognised symptoms across the sample population. Age (<65 years, sex (female and high socio-economic status contributed to a higher recognition of symptoms. Smoking was recognised as a cause of lung cancer, yet ever-smokers were less likely to recognise the risk of lung cancer due to second-hand smoke (OR 0.7 95 % CI 0.5–0.9. Conclusion While there was some recognition of risk factors

    The selection of topical and systemic therapies for the treatment of venous ulcers with signs of infection is challenging and should be accompanied by specific precautionary measures to protect against cross-contamination in the presence of multidrug-resistant microorganisms. However, there are still no clinical indicators for this situation, and confirmation of resistant strains occurs through culture and sensitivity, which can take up to 14 days. During this period, protective measures may no longer be taken, contributing to the spread of these pathogens. This study aimed to analyze the relationship between clinical signs and symptoms of infection in venous ulcers and the presence of antimicrobial-resistant Staphylococcus aureus and/or Pseudomonas spp. A cross-sectional study was developed including 69 patients with 98 venous ulcers. Clinical observation protocol was applied to detect infection indicators established by the European Wound Management Association and microbiological analysis of samples of the lesions. Fisher's exact test and χ 2 were used for analyses (P 70%): discoloration of the opaque type and/or dark brick red and increased exudate volume; 31 (31.6%) ulcer samples showed positive culture for the bacteria studied. There was no relationship between signs and symptoms of infection and the presence of multidrug-resistant microorganisms. Taking into account the percentage of lesions with resistant strains, for safe care, contact precautionary measures should be implemented in the treatment rooms, in addition to standard precautions.

    Full Text Available Data collected during the 2012 Ebola virus disease (EVD epidemic in the Democratic Republic of the Congo were analysed for clinical signs, symptoms and case fatality of EVD caused by Bundibugyo virus (BDBV, establishment of differential diagnoses, description of medical treatment and evaluation of the quality of clinical documentation. In a quantitative observational prospective study, global epidemiological data from 52 patients (34 patients within the community, 18 patients treated in the Ebola Treatment Centre were entered anonymously into a database, subsequently matched and analysed. Relevant findings include an over-representation of females among community EVD cases (85.3% and of community EVD cases in the age group of 15-54 years (82.4%. All ETC patients had fever (55.6% of all 18 ETC patients during their hospital stay or self-reported fever (88.2% upon admission at some point of time during their illness. Major symptoms of ETC patients during hospital stay included asthenia (82.4%, anorexia (82.4%, myalgia (70.6%, sore throat/difficulty swallowing (70.6%, arthralgia (76.5% and nausea (70.6%. Gastrointestinal signs and symptoms (nausea, diarrhoea, vomiting (76.4% as well as general pain (94.1% were frequent in ETC patients. The median duration of EVD was 18 days, while the mean incubation period was 11.3 days. Differential diagnosis of EVD included malaria (28.3%, intestinal parasitosis (10.9%, and infectious syndrome (10.9%. There was also an important variation in clinical evolvement. Quality of documentation was adversely affected by the way patient file contents were transferred from inside to outside the high-risk zone, entailing a mean mismatch value of 27.3% between patient file contents inside vs. outside the high-risk zone. This study adds further description of EVD (frequently non-specific signs and symptoms, non frequent bleeding, a long incubation period, long duration of disease and emphasizes the need for improving

  11. Predicting acute uncomplicated urinary tract infection in women: a systematic review of the diagnostic accuracy of symptoms and signs

    2010-10-24

    Abstract Background Acute urinary tract infections (UTI) are one of the most common bacterial infections among women presenting to primary care. However, there is a lack of consensus regarding the optimal reference standard threshold for diagnosing UTI. The objective of this systematic review is to determine the diagnostic accuracy of symptoms and signs in women presenting with suspected UTI, across three different reference standards (102 or 103 or 105 CFU\\/ml). We also examine the diagnostic value of individual symptoms and signs combined with dipstick test results in terms of clinical decision making. Methods Searches were performed through PubMed (1966 to April 2010), EMBASE (1973 to April 2010), Cochrane library (1973 to April 2010), Google scholar and reference checking. Studies that assessed the diagnostic accuracy of symptoms and signs of an uncomplicated UTI using a urine culture from a clean-catch or catherised urine specimen as the reference standard, with a reference standard of at least ≥ 102 CFU\\/ml were included. Synthesised data from a high quality systematic review were used regarding dipstick results. Studies were combined using a bivariate random effects model. Results Sixteen studies incorporating 3,711 patients are included. The weighted prior probability of UTI varies across diagnostic threshold, 65.1% at ≥ 102 CFU\\/ml; 55.4% at ≥ 103 CFU\\/ml and 44.8% at ≥ 102 CFU\\/ml ≥ 105 CFU\\/ml. Six symptoms are identified as useful diagnostic symptoms when a threshold of ≥ 102 CFU\\/ml is the reference standard. Presence of dysuria (+LR 1.30 95% CI 1.20-1.41), frequency (+LR 1.10 95% CI 1.04-1.16), hematuria (+LR 1.72 95%CI 1.30-2.27), nocturia (+LR 1.30 95% CI 1.08-1.56) and urgency (+LR 1.22 95% CI 1.11-1.34) all increase the probability of UTI. The presence of vaginal discharge (+LR 0.65 95% CI 0.51-0.83) decreases the probability of UTI. Presence of hematuria has the highest diagnostic utility, raising the post-test probability of

    Delayed onset muscle soreness (DOMS) occurs after unaccustomed physical activity or competitive sport, resulting in stiff, painful muscles with impaired function. Acustat electro-membrane microcurrent therapy has been used to treat postoperative pain and soft tissue injury; however, its efficacy in reducing symptoms of muscle damage is not known. Thirty healthy men were recruited for a double-blind, placebo-controlled trial. The muscles of their nondominant arms were damaged using an eccentric-exercise protocol. Subjects were then randomly assigned to treatment with either Acustat or a matching placebo membrane for 96 h and monitored for a total of 168 h. Subjects in both groups experienced severe pain and swelling of the elbow flexors after the eccentric exercise. After 24 h, the elbow joint angle of the placebo group had increased significantly more than those in the Acustat group (13.7 +/- 8.9 degrees vs 7.5 +/- 5.5 degrees; placebo vs Acustat, P microcurrent therapy reduces the severity of the symptoms. The mechanisms of action are unknown but are likely related to maintenance of intracellular Ca2+ homeostasis after muscle damaging exercise.

    Limited cutaneous systemic sclerosis (lcSSc) was formerly known as CREST syndrome in reference to the associated clinical features: Calcinosis, Raynaud's phenomenon, Esophageal dysfunction, Sclerodactyly, and Telangiectasias. The transforming growth factor beta (TGF-β) has been identified has a major player in the pathogenic process, while low level light therapy (LLLT) has been shown to modulate this cytokine superfamily. This case study was conducted to assess the efficacy of 940nm using microsecond domain pulsing and continuous wave mode (CW) on osteoarticular signs and symptoms associated with lcSSc. The patient was treated two to three times a week for 13 weeks, using a sequential pulsing mode on one elbow, and a CW mode on the other. Efficacy assessments included inflammation, symptoms, pain, and health scales, patient satisfaction, clinical global impression, and adverse effects monitoring. Significant functional and morphologic improvements were observed after LLLT, with best results seen with the pulsing mode. No significant adverse effects were noted. Two mechanisms of action may be at play. The 940nm wavelength provides inside-out heating possibly vasodilating capillaries which in turn increases catabolic processes leading to a reduction of in situ calcinosis. LLLT may also improve symptoms by triggering a cascade of cellular reactions, including the modulation of inflammatory mediators.

    Spontaneous pain, hyperalgesia as well as sensory abnormalities, autonomic, trophic, and motor disturbances are key features of Complex Regional Pain Syndrome (CRPS). This study was conceived to comprehensively characterize the interaction of these symptoms in 118 patients with chronic upper limb CRPS (duration of disease: 43±23 months). Disease-related stress, depression, and the degree of accompanying motor disability were likewise assessed. Stress and depression were measured by Posttraumatic Stress Symptoms Score and Center for Epidemiological Studies Depression Test. Motor disability of the affected hand was determined by Sequential Occupational Dexterity Assessment and Michigan Hand Questionnaire. Sensory changes were assessed by Quantitative Sensory Testing according to the standards of the German Research Network on Neuropathic Pain. Almost two-thirds of all patients exhibited spontaneous pain at rest. Hand force as well as hand motor function were found to be substantially impaired. Results of Quantitative Sensory Testing revealed a distinct pattern of generalized bilateral sensory loss and hyperalgesia, most prominently to blunt pressure. Patients reported substantial motor complaints confirmed by the objective motor disability testings. Interestingly, patients displayed clinically relevant levels of stress and depression. We conclude that chronic CRPS is characterized by a combination of ongoing pain, pain-related disability, stress and depression, potentially triggered by peripheral nerve/tissue damage and ensuing sensory loss. In order to consolidate the different dimensions of disturbances in chronic CRPS, we developed a model based on interaction analysis suggesting a complex hierarchical interaction of peripheral (injury/sensory loss) and central factors (pain/disability/stress/depression) predicting motor dysfunction and hyperalgesia.

    Tinea pedis is the most common dermatophyte infection. Treatment is critical to alleviate pruritic symptoms, to reduce the risk for secondary bacterial infection, and to limit the spread of infection to other body sites or other individuals. The objective of this study was to compare the abilities of econazole nitrate topical foam, 1% and ketoconazole cream (2%) to reduce pruritus, thus improving quality of life, and to determine patient preference for the foam product versus the cream product in patients with interdigital tinea pedis. A single-center, investigator-blinded, observational pilot study was conducted to compare econazole nitrate topical foam (1%) to ketoconazole cream (2%). In this split-body study, 20 subjects received both econazole nitrate topical foam and ketoconazole cream and applied the medications daily to either the right or left foot for 14 days. Improvements in patient quality of life (pruritus) and patient preference were measured using the pruritus visual analog scale (VAS), Skindex-16, and patient preference questionnaires. Nineteen subjects completed the study and one subject was lost to follow-up. Reductions in VAS scores of econazole nitrate topical foam were significantly greater than those of ketoconazole cream, indicating the superiority of the econazole nitrate foam in reducing pruritus. Skindex-16 data showed significant reductions in total scores and individual domains, including patient symptom, emotional, and functional domains, by the final visit. Since each subject received both medications the questionnaire was not medication-specific. Responses to patient preference questionnaires showed that econazole nitrate topical foam,1% was rated as "good" or "excellent" in all measures assessed. One adverse event was noted. In patients with interdigital tinea pedis, application of econazole nitrate topical foam 1% twice daily for two weeks was clinically effective and significantly superior to ketoconazole cream 2% in reducing

    This study independently examined the effects of three hydrotherapy interventions on the physiological and functional symptoms of delayed onset muscle soreness (DOMS). Strength trained males (n = 38) completed two experimental trials separated by 8 months in a randomised crossover design; one trial involved passive recovery (PAS, control), the other a specific hydrotherapy protocol for 72 h post-exercise; either: (1) cold water immersion (CWI: n = 12), (2) hot water immersion (HWI: n = 11) or (3) contrast water therapy (CWT: n = 15). For each trial, subjects performed a DOMS-inducing leg press protocol followed by PAS or one of the hydrotherapy interventions for 14 min. Weighted squat jump, isometric squat, perceived pain, thigh girths and blood variables were measured prior to, immediately after, and at 24, 48 and 72 h post-exercise. Squat jump performance and isometric force recovery were significantly enhanced (P < 0.05) at 24, 48 and 72 h post-exercise following CWT and at 48 and 72 h post-exercise following CWI when compared to PAS. Isometric force recovery was also greater (P < 0.05) at 24, 48, and 72 h post-exercise following HWI when compared to PAS. Perceived pain improved (P < 0.01) following CWT at 24, 48 and 72 h post-exercise. Overall, CWI and CWT were found to be effective in reducing the physiological and functional deficits associated with DOMS, including improved recovery of isometric force and dynamic power and a reduction in localised oedema. While HWI was effective in the recovery of isometric force, it was ineffective for recovery of all other markers compared to PAS.

    As a mechanisms-based classification of pain \\'nociceptive pain\\' (NP) refers to pain attributable to the activation of the peripheral receptive terminals of primary afferent neurones in response to noxious chemical, mechanical or thermal stimuli. The symptoms and signs associated with clinical classifications of NP have not been extensively studied. The purpose of this study was to identify symptoms and signs associated with a clinical classification of NP in patients with low back (± leg) pain. Using a cross-sectional, between-subjects design; four hundred and sixty-four patients with low back (± leg) pain were assessed using a standardised assessment protocol after which their pain was assigned a mechanisms-based classification based on experienced clinical judgement. Clinicians then completed a clinical criteria checklist indicating the presence\\/absence of various symptoms and signs. A regression analysis identified a cluster of seven clinical criteria predictive of NP, including: \\'Pain localised to the area of injury\\/dysfunction\\

    In order to assess the current nutrition status of Mongolian population, including rickets and vitamin D deficiency of children and women, the Fourth National Nutrition Cross-Sectional Survey was conducted in 21 aimags (provinces) of 4 economic regions of the country and capital city Ulaanbaatar in 2010. Children of age under five years, and non-pregnant women of reproductive age were used as subjects for assessing rickets and vitamin D deficiency. A total of 400 households were randomly selected from each of 4 economic regions and Ulaanbaatar city. Clinical examinations were performed on 706 children of age under five years. Interviews were used to assess vitamin D supplement use. The serum level of 25-hydroxyvitamin D was measured in 524 children aged 6-59 months and in 867 women of reproductive age. This survey found that 21.8% of children had vitamin D deficiency, 20.6% had low vitamin D reserve, and 30.0% of women had vitamin D deficiency and 22.2% had low vitamin D reserve. The prevalence of vitamin D deficiency in children (35.0%, 95% CI, 24.7-47.0) and women (54.9%, 95% CI 45.5-64.0) in the Eastern Region was (35.0%, 95% CI, 24.7-47.0) significantly higher than in the Western, Khangai, Central Regions, and Ulaanbaatar. Further it was found that 27.4% of children under-two years had received vitamin D supplementation. The proportion of children, who did not receive vitamin D supplementation had a higher prevalence of vitamin D deficiency than that of the children of the Eastern Region. None of the women who were involved in this survey had received vitamin D supplementation; 10.2% of them had delivered in the past 12 months, and 22.5% were breastfeeding. The prevalence of classic signs and symptoms of rickets were commonly reported among children of age under five, and skeletal abnormalities more commonly reported in children aged 12-47 months. In conclusion, there is a high prevalence of classic signs and symptoms of rickets in children of age under five

    Infection with Toxoplasma gondii in brain may cause some symptoms that resemble those in women with premenstrual syndrome. To determine the association of T. gondii infection with symptoms and signs of premenstrual syndrome, we examined 489 women aged 30–40 years old. Sera of participants were analyzed for the presence of anti-Toxoplasma IgG and IgM antibodies using enzyme-linked immunoassays (EIA) and T. gondii DNA by polymerase chain reaction (PCR). Anti-T. gondii IgG antibodies were found in 38 (7.8%) of the women studied. Anti-T. gondii IgM antibodies were found in 13 (34.2%) of the 38 IgG seropositive women. Logistic regression showed two variables associated with seropositivity to T. gondii: presence of diarrhea (odds ratio [OR] = 6.10; 95% confidence interval [CI]: 1.37–27.85; P = 0.01) and weight gain (OR = 2.89; 95% CI: 1.37–6.07; P = 0.005), and two variables associated with high (>150 IU/ml) levels of IgG against T. gondii: presence of diarrhea (OR = 7.40; 95% CI: 1.79–30.46; P = 0.006) and abdominal inflammation (OR = 3.38; 95% CI: 1.13–10.10; P = 0.02). Positivity to EIA IgG and PCR was positively associated with obesity and negatively associated with joint pain by bivariate analysis. Our study for the first time reveals a potential association of T. gondii infection with clinical manifestations of premenstrual syndrome. PMID:27980858

    Due to a relative lack of outpatient heart failure (HF) clinical registries, we aimed to describe symptoms, signs, and medication treatment among ambulatory patients with heart failure (HF) over time. Using health records from 234 PINNACLE (Practice Innovation and Clinical Excellence) U.S. cardiology practices (2008-2014), serial visits for patients with HF were characterized. Symptoms, signs, and HF medications (angiotensin-converting enzyme inhibitors [ACEI], angiotensin receptor blockers [ARB], beta blockers [BB], and diuretics) were compared between visits. Among 763,331 patients with HF, 550,581 had ≥2 clinic visits < 1 year apart, with 2,998,444 visit pairs. In the 12 months following an index visit, patients had a mean of 2.5 ± 2.3 additional visits. Recorded index visit symptoms ranged from dyspnea (53.6%) to orthopnea (23.1%); signs ranged from peripheral edema (52.2%) to hepatomegaly (0.6%). Of those with ejection fraction < 40%, ACEI was prescribed in 58.6%, ARB in 18.5%, BB in 85.2%, and diuretics in 70.0%. Between-visit recorded changes were infrequent: dyspnea appeared in 3.8%, resolved in 2.7%; NYHA class increased in 2.9%, decreased in 2.9%; number of signs increased in 6.0%, decreased in 5.1%; ACEI/ARB or BB added in 6.4%, removed in 6.2%; diuretic added in 3.7%, removed in 3.8%. Changes in recorded symptoms were rarely associated with initiation or discontinuation in HF medication classes. Ambulatory HF care in U.S. cardiology practices seldom recorded changes in symptoms, signs, and medication class. Although templated medical records and absence of medication dosing likely underestimated the degree to which clinical changes occur over serial visits for HF, these PINNACLE data suggest opportunities for greater symptom-based and therapy-focused visits.

    2011-06-01

    Abstract Background Stratifying patients with a sore throat into the probability of having an underlying bacterial or viral cause may be helpful in targeting antibiotic treatment. We sought to assess the diagnostic accuracy of signs and symptoms and validate a clinical prediction rule (CPR), the Centor score, for predicting group A β-haemolytic streptococcal (GABHS) pharyngitis in adults (> 14 years of age) presenting with sore throat symptoms. Methods A systematic literature search was performed up to July 2010. Studies that assessed the diagnostic accuracy of signs and symptoms and\\/or validated the Centor score were included. For the analysis of the diagnostic accuracy of signs and symptoms and the Centor score, studies were combined using a bivariate random effects model, while for the calibration analysis of the Centor score, a random effects model was used. Results A total of 21 studies incorporating 4,839 patients were included in the meta-analysis on diagnostic accuracy of signs and symptoms. The results were heterogeneous and suggest that individual signs and symptoms generate only small shifts in post-test probability (range positive likelihood ratio (+LR) 1.45-2.33, -LR 0.54-0.72). As a decision rule for considering antibiotic prescribing (score ≥ 3), the Centor score has reasonable specificity (0.82, 95% CI 0.72 to 0.88) and a post-test probability of 12% to 40% based on a prior prevalence of 5% to 20%. Pooled calibration shows no significant difference between the numbers of patients predicted and observed to have GABHS pharyngitis across strata of Centor score (0-1 risk ratio (RR) 0.72, 95% CI 0.49 to 1.06; 2-3 RR 0.93, 95% CI 0.73 to 1.17; 4 RR 1.14, 95% CI 0.95 to 1.37). Conclusions Individual signs and symptoms are not powerful enough to discriminate GABHS pharyngitis from other types of sore throat. The Centor score is a well calibrated CPR for estimating the probability of GABHS pharyngitis. The Centor score can enhance appropriate

    The aim of this study was to investigate the association between patterns of jaw motor activity during sleep and clinical signs and symptoms of sleep bruxism. A total of 35 university students and staff members participated in this study after providing informed consent. All participants were divided into either a sleep bruxism group (n = 21) or a control group (n = 14), based on the following clinical diagnostic criteria: (1) reports of tooth-grinding sounds for at least two nights a week during the preceding 6 months by their sleep partner; (2) presence of tooth attrition with exposed dentin; (3) reports of morning masticatory muscle fatigue or tenderness; and (4) presence of masseter muscle hypertrophy. Video-polysomnography was performed in the sleep laboratory for two nights. Sleep bruxism episodes were measured using masseter electromyography, visually inspected and then categorized into phasic or tonic episodes. Phasic episodes were categorized further into episodes with or without grinding sounds as evaluated by audio signals. Sleep bruxism subjects with reported grinding sounds had a significantly higher total number of phasic episodes with grinding sounds than subjects without reported grinding sounds or controls (Kruskal-Wallis/Steel-Dwass tests; P bruxism subjects with tooth attrition exhibited significantly longer phasic burst durations than those without or controls (Kruskal-Wallis/Steel-Dwass tests; P bruxism subjects with morning masticatory muscle fatigue or tenderness exhibited significantly longer tonic burst durations than those without or controls (Kruskal-Wallis/Steel-Dwass tests; P bruxism represents different aspects of jaw motor activity during sleep. © 2016 European Sleep Research Society.

    There is evidence that water-loss dehydration is common in older people and associated with many causes of morbidity and mortality. However, it is unclear what clinical symptoms, signs and tests may be used to identify early dehydration in older people, so that support can be mobilised to improve hydration before health and well-being are compromised. To determine the diagnostic accuracy of state (one time), minimally invasive clinical symptoms, signs and tests to be used as screening tests for detecting water-loss dehydration in older people by systematically reviewing studies that have measured a reference standard and at least one index test in people aged 65 years and over. Water-loss dehydration was defined primarily as including everyone with either impending or current water-loss dehydration (including all those with serum osmolality ≥ 295 mOsm/kg as being dehydrated). Structured search strategies were developed for MEDLINE (OvidSP), EMBASE (OvidSP), CINAHL, LILACS, DARE and HTA databases (The Cochrane Library), and the International Clinical Trials Registry Platform (ICTRP). Reference lists of included studies and identified relevant reviews were checked. Authors of included studies were contacted for details of further studies. Titles and abstracts were scanned and all potentially relevant studies obtained in full text. Inclusion of full text studies was assessed independently in duplicate, and disagreements resolved by a third author. We wrote to authors of all studies that appeared to have collected data on at least one reference standard and at least one index test, and in at least 10 people aged ≥ 65 years, even where no comparative analysis has been published, requesting original dataset so we could create 2 x 2 tables. Diagnostic accuracy of each test was assessed against the best available reference standard for water-loss dehydration (serum or plasma osmolality cut-off ≥ 295 mOsm/kg, serum osmolarity or weight change) within each study.

    Low back pain (LBP) symptoms and signs are nonspecific. If required, diagnostic blocks may find the source of pain, but indicators of suspect diagnosis must be defined to identify anatomical targets. To reach a consensus from an expert panel on the indicators for the most common causes of LBP. A 3-round (2 telematic and 1 face-to-face) modified Delphi survey with a questionnaire on 78 evidence-based indicators of 7 LBP etiologies was completed by 23 experts. 98.7% of the questionnaire was consensuated. The most accepted indicators were for zygapophysial joint pain, painful ipsilateral paravertebral palpation, worsening with trunk extension, paravertebral musculature spasm on the affected articulation, and referred pain above the knee, without radicular pattern. For sacroiliac joint pain, unilateral pain when seating, with at least 3 described provoking tests: Approximation; gapping; Patrick's; Gaenslen's; thigh thrust; Fortin finger; and Gillet's tests. For discogenic pain, midline pain that may be provoked by pressure on the spinal processes at the affected level; for quadratus lumborum muscle, painful palpation on both the L1 level paravertebral region, referred to iliac crest, and the iliac crest, referred to greater trochanter. For iliopsoas muscle, pain elicited by thigh flexion, referred to buttock, inguinal region, and anterior thigh. For pyramidal muscle, pain while sitting on the affected side and positive Freiberg's test. For radicular pain, paresthesias and positive Lassègue's test at 60°. Seventy-seven diagnostic suspect indicators of LBP conditions were consensuated. These may facilitate conservative or interventional pain management decision-making. © 2013 World Institute of Pain.

  1. Symptoms and signs in particular: the influence of the medical concern on the shape of physician-patient talk.

    Hamilton, Heidi E

    2004-01-01

    Talk between physicians and their patients has been shown to be shaped by participant characteristics,phase of the visit, and professional and institutional constraints. Surprisingly, the medical concern that brings the participants together has not been systematically and thoroughly investigated as a shaping influence on such talk. Based on a synthesis of separate interactional sociolinguistic studies of ten different medical concerns involving 395 patients and 105 physicians, I identify seven major differences across medical issues that may shape physician-patient discourse. In this paper I then focus on the first of these seven--the indication of the medical problem. Beginning with the traditional medical distinction between symptoms and signs, I characterize the kinds of evidence introduced by physicians and patients in talk about medical concerns. I then turn to the fuller discourse context of these reports, specifically examining how the indications emerge and play themselves out in the visit. Following Becker (1995b), I identify a two-step 'attunement' process, in which one participant (1) uses language to move toward a clearer understanding of the other's evidence and then displays this emerging understanding, and (2) takes up a stance toward the other's evidence--either corroborating or dismissing it with evidence of his or her own. In closing, I argue the importance of considering the shaping influences of differences across medical concerns, both for discourse analysts in their quest to account for particularities within physician-patient discourse as well as for healthcare professionals who believe that more attuned communication practices can result in better medical practices.

    Temporomandibular Disorder (TMD) has attained a prominent role within the context of dental care due to its high prevalence. The aim of this study was to evaluate the prevalence of signs and symptoms of TMD in students at the State University of West of Paraná (UNIOESTE) with natural dentition, and in patients with removable partial dentures and double complete dentures. A total of 210 randomly selected individuals of both genders were evaluated, being divided into three groups: seventy students at the UNIOESTE with natural dentition (Group 1), seventy patients with removable partial dentures (Group 2) and seventy patients with bimaxillary complete dentures (Group 3). The data were collected by a single examiner using the American Academy of Orofacial Pain questionnaire for triage, where a single affirmative response to any of the situations mentioned was enough to carry out clinical evaluation. Kolmogorov Smirnov, Mann Whitney, Chi-Square, ANOVA and Tukey's statistical tests were performed. The most prevalent signs and symptoms of TMD in Group 1 were pain or difficulty in chewing or talking, perception of recent change in bite and deviations during the course of mandibular movements. In Group 2 they were perceptions of recent changes in the bite, deflections in the mandibular movements, presence of joint sounds, pain during excursive movements and muscle tenderness. The most prevalent signs and symptoms in Group 3 were limited to mouth opening and poor stability and retention of at least one of the prostheses. Group 3 also reported having received treatment for headaches or facial pain with a high prevalence. Group 2 had the highest prevalence of signs and symptoms. Prevalence was similar in Groups 1 and 3.

    Full Text Available Achieving safe and readily accessible sources for cell replacement therapy in Parkinson's disease (PD is still a challenging unresolved issue. Recently, a primitive neural crest stem cell population (hOMSC was isolated from the adult human oral mucosa and characterized in vitro and in vivo. In this study we assessed hOMSC ability to differentiate into dopamine-secreting cells with a neuronal-dopaminergic phenotype in vitro in response to dopaminergic developmental cues and tested their therapeutic potential in the hemi-Parkinsonian rat model. We found that hOMSC express constitutively a repertoire of neuronal and dopaminergic markers and pivotal transcription factors. Soluble developmental factors induced a reproducible neuronal-like morphology in the majority of hOMSC, downregulated stem cells markers, upregulated the expression of the neuronal and dopaminergic markers that resulted in dopamine release capabilities. Transplantation of these dopaminergic-induced hOMSC into the striatum of hemi-Parkinsonian rats improved their behavioral deficits as determined by amphetamine-induced rotational behavior, motor asymmetry and motor coordination tests. Human TH expressing cells and increased levels of dopamine in the transplanted hemispheres were observed 10 weeks after transplantation. These results demonstrate for the first time that soluble factors involved in the development of DA neurons, induced a DA phenotype in hOMSC in vitro that significantly improved the motor function of hemiparkinsonian rats. Based on their neural-related origin, their niche accessibility by minimal-invasive procedures and their propensity for DA differentiation, hOMSC emerge as an attractive tool for autologous cell replacement therapy in PD.

    As a mechanisms-based classification of pain \\'central sensitisation pain\\' (CSP) refers to pain arising from a dominance of neurophysiological dysfunction within the central nervous system. Symptoms and signs associated with an assumed dominance of CSP in patients attending for physiotherapy have not been extensively studied. The purpose of this study was to identify symptoms and signs associated with a clinical classification of CSP in patients with low back (± leg) pain. Using a cross-sectional, between-subjects design; four hundred and sixty-four patients with low back (± leg) pain were assessed using a standardised assessment protocol. Patients\\' pain was assigned a mechanisms-based classification based on experienced clinical judgement. Clinicians then completed a clinical criteria checklist specifying the presence or absence of various clinical criteria. A binary logistic regression analysis with Bayesian model averaging identified a cluster of three symptoms and one sign predictive of CSP, including: \\'Disproportionate, non-mechanical, unpredictable pattern of pain provocation in response to multiple\\/non-specific aggravating\\/easing factors\\

    The aim of this longitudinal study was to determine the effects of orthognathic surgery on signs and symptoms of temporomandibular disorders (TMD) and on pressure pain thresholds (PPTs) of the jaw muscles. Fourteen consecutive class III patients undergoing pre-surgical orthodontic treatment were treated by combined Le Fort I osteotomy and bilateral sagittal ramus osteotomy. The clinical examination included the assessment of signs and symptoms of TMD and the assessment of PPTs of the masseter and temporalis muscles. Anamnestic, clinical and algometric data were collected during five sessions over a 1-year period. Seven out of 14 patients presented with disc displacement with reduction at baseline, whereas four patients (two of them were new cases) did so at the end of follow up (p>0.05). None of the patients were diagnosed with myofascial pain of the jaw muscles at the beginning or end of follow up. PPTs of the masseter and temporalis muscles did not change significantly from baseline values throughout the whole study period. The occurrence of signs and symptoms of TMD fluctuates with an unpredictable pattern after orthognathic surgery for class III malocclusions.

    Full Text Available In recent years, substantial changes have occurred in the structure of oral mucosa diseases, in particular an increased ratio of precancerous diseases, so that an effective non-invasive detection of any sign of malignancy appears as an urgent and most actual task of dentistry. Aim: To study the proliferative activity of epithelial cells in Ki-67 antigenin patients with leukoplakia of the oral mucosa. Materials and method: A complex clinical and laboratory examination was performed on 155 patients with oral leukoplakia, who addressed the Operative Dentistry Department of the “A.A.Bogomolets” National Medical University of Kiev between 2010 and 2014. All patients have been subjected to a careful clinical examination, which included: dental anamnesis, visual inspection, oral examination and digital palpation of oral mucosa and tongue mucosa, biopsy of leukoplakia lesions for cytological and histological examination. Results: Histological evaluation of the material has been performed according to the WHO (2005 classification of leukoplakia. 10 (14% sites of unaltered mucosa, 10 (14% samples of hyperkeratosis without atypia, 14 (19% biopsy specimens of hyperkeratosis SIN1, 15 (21% – hyperkeratosis SIN2, 10 (14% - SIN3 and 13 (18% cases of squamous cell carcinoma were evidenced. Immunohistochemical investigation evidenced the presence of protein Ki-67 in the nuclei of epithelial cells. In the unmodified epithelium of the oral mucosa, all epithelial cells with stained nuclei are virtually located in the basal layer. Conclusion: Against the general increase of the proliferative activity of epithelial cells with increasing SIN, a characteristic distribution of proliferating cells in the thickness of the epithelium was revealed for each studied group, as follows: in the control group and in leukoplakia without atypia, immunopositive cells are located in the basal layer, in leukoplakia (SIN1, SIN2 and SIN3 – in parabasal position while, in squamous

    Studies on the relationships between postural deviations and the temporomandibular system (TS) functional health are controversial and inconclusive. This study stems from the hypothesis that such inconclusiveness is due to authors considering functional pathologies of the TS (FPTS) as a whole, without taking into account subjects' specific FPTS signs and symptoms. Based on the author and collaborators' previous studies, the present study analyzed data on body posture from a sample of 50 subjects with (30) and without (20) FPTS. Correlation analyses were applied, taking as independent variables age, sex, Helkimo anamnestic, occlusal, and dysfunction indices, as well as FPTS specific signs and symptoms. Postural assessments of the head, cervical spine, shoulders, lumbar spine, and hips were the dependent variables. Linear regression equations were built that proved to partially predict the presence and magnitude of body posture deviations by drawing on subjects' characteristics and specific FPTS symptoms. Determination coefficients for these equations ranged from 0.082 to 0.199 in the univariate, and from 0.121 to 0.502 in the multivariate regression analyses. Results show that factors intrinsic to the subjects or the TS may potentially interfere in results of studies that analyze relationships between FPTS and body posture. Furthermore, a trend to specificity was found, e.g. the degree of cervical lordosis was found to correlate to age and FPTS degree of severity, suggesting that some TS pathological features, or malocclusion, age or sex, may be more strongly correlated than others with specific posture patterns.

    Evidence suggests that individuals with Alzheimer's disease (AD) are often diagnosed in the later stages of their disease with a poor prognosis. This study aimed to identify patterns in signs and symptoms preceding the clinical diagnosis of AD to suggest a predictive model for earlier diagnosis of the disease in the primary care. A retrospective medical record review; nested case control design. Participants included one hundred and nine patients from three general practice (GP) surgeries in Milton Keynes and Luton Clinical Commissioning groups (CCG) (37 cases with AD and 72 controls without AD). A retrospective analysis using the logistic regression of the presence of signs and symptoms before the diagnosis of AD was attained. Identification of the timing and sequence of appearance of these presentations as first reported before the clinical diagnosis was measured. Episodic memory with an odds ratio of 1.85 was the most frequent presentation, documented in 1.38% of the controls and 75.6% in cases. Auditory disturbance with an odds ratio of 3.03, which has not previously been noted except in the form of auditory hallucination, could have a diagnostic value. Auditory disturbance, which occurred mostly in the Caucasian females, could discriminate individuals with AD from those without. The symptom, which presented up to 14.5 (mean time) years prior to clinical diagnosis, was identified in Caucasians and mixed race individuals only.

    Limited cutaneous systemic sclerosis (lcSSc) was formerly known as CREST syndrome in reference to the associated clinical features: calcinosis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasias. The transforming growth factor beta has been identified as a major player in the pathogenic process, where low-level light therapy (LLLT) has been shown to modulate this cytokine superfamily. This case study was conducted to assess the efficacy of 940 nm using millisecond pulsing and continuous wave (CW) modes on osteoarticular signs and symptoms associated with lcSSc. The patient was treated two to three times a week for 13 weeks using a sequential pulsing mode on one elbow and a CW mode on the other. Efficacy assessments included inflammation, symptoms, pain, health scales, patient satisfaction, clinical global impression, and adverse effects monitoring. Considerable functional and morphologic improvements were observed after LLLT, with the best results seen with the pulsing mode. No adverse effects were noted. Pulsed LLLT represents a treatment alternative for osteoarticular signs and symptoms in limited scleroderma (CREST syndrome).

    Objective Late diagnosis of Alzheimer’s disease (AD) may be due to diagnostic uncertainties. We aimed to determine the sequence and timing of the appearance of established early signs and symptoms in people who are subsequently diagnosed with AD. Methods We used systematic review methodology to investigate the existing literature. Articles were reviewed in May 2016, using the following databases: MEDLINE, PsycINFO, CINAHL, British Nursing Index, PubMed central and the Cochrane library, with no language restriction. Data from the included articles were extracted independently by two authors and quality assessment was undertaken with the quality assessment and diagnostic accuracy tool-2 (QUADAS tool-2 quality assessment tool). Results We found that depression and cognitive impairment were the first symptoms to appear in 98.5% and 99.1% of individuals in a study with late-onset AD (LOAD) and 9% and 80%, respectively, in early-onset AD (EOAD). Memory loss presented early and was experienced 12 years before the clinically defined AD dementia in the LOAD. However, the rapidly progressive late-onset AD presented predominantly with 35 non-established focal symptoms and signs including myoclonus (75%), disturbed gait (66%) and rigidity. These were misdiagnosed as symptoms of Creutzfeldt-Jacob disease (CJD) in all the cases. The participant with the lowest mini-mental state examination score of 25 remained stable for 2 years, which is consistent with the score of the healthy family members. Conclusions The findings of this review suggest that neurological and depressive behaviours are an early occurrence in EOAD with depressive and cognitive symptoms in the measure of semantic memory and conceptual formation in LOAD. Misdiagnosis of rapidly progressive AD as CJD and the familial memory score can be confounding factors while establishing a diagnosis. However, the study was limited by the fact that each one of the findings was based on a single study. PMID:28851777

    Objective. To determine the first signs and symptoms, and the clinical, biological and radiological characteristics of patients with early SpA. Methods. A total of 150 SpA patients were selected from 2367 listed in REGISPONSER (Registro Español de Espondiloartritis de la Sociedad Española de Reumatología). The inclusion criterion was a disease course of ⩽2 yrs from the onset of symptoms or the appearance of the first sign of disease. Results. Forty-six patients had AS, 51 psoriatic SpA (Ps-SpA), 43 uSpA, 5 ReA, 4 IBD arthropathy and 1 JCA. The mean age at onset of symptoms and at diagnosis was higher in Ps-SpA group (48.1 ± 13.6 and 48.5 ± 13.6 yrs) than in AS group (38.1 ± 12.8 and 38.9 ± 12.7 yrs) and uSpA group (36.3 ± 11.5 and 36.9 ± 11.4 yrs). The most frequent signs or symptoms were back pain: 72% AS group and 56% uSpA group. Lower limb arthritis was the first symptom in 57% Ps-SpA patients, 35% uSpA patients and 20% AS patients; upper limb arthritis was the first symptom in 53% Ps-SpA group and <16% of the remainder. Compared with longer duration disease, at onset, AS patients report upper limb arthritis more frequently and uSpA patients report more of enthesitis. Early radiological sacroiliitis was observed in all AS patients, of whom 54% had Grade II, 39% had Grade III and 7% had Grade IV. Conclusions. In our population, the first manifestations of SpA were low back pain and SI syndrome in AS and uSpA patients and peripheral arthritis in the Ps-SpA group. We can find early SI joint affectation in AS patients. PMID:19208685

    Introduction Foreign body in the oral cavity may be asymptomatic for long time and only sometimes it can lead to a typical granulomatous foreign body reaction. Some patients may complain of oral pain and present signs of inflammation with purulent discharge. A granuloma is a distinct, compact microscopic structure composed of epithelioid-shaped macrophages typically surrounded by a rim of lymphocytes and filled with fibroblasts and collagen. Nowadays, the increase of cosmetic invasive procedures such as injection of prosthetic materials in lips and cheeks may lead to unusual forms of inflammatory granulomas. Objectives Describe an unusual presentation of a foreign body reaction in the buccal mucosa due to previous injection of cosmetic agent. Resumed Report A 74-year-old woman was referred to the Department of Otorhinolaryngology, Head and Neck Surgery to investigate the presence of multiple painless, bilateral nodules in the buccal mucosa, with progressive growth observed during the previous 2 months. The histologic results showed a foreign body inflammatory reaction. Conclusion Oral granulomatosis lesions represent a challenging diagnosis for clinicians and a biopsy may be necessary. Patients may feel ashamed to report previous aesthetic procedures, and the clinicians must have a proactive approach.

    2003-01-01

    Diabetes mellitus is the most common endocrinologic disease all over the world. 150 million people suffer from this disease, in Poland about 2 million. The disease on the basis of the onset and pathophysiology may be divided into type I and type II. Pathophysiologic changes include diabetic microangiopathy, macroangiopathy and neuropathy. The most common presentations in head and neck are otitis externa, hypoacusis, vertigo, disequilibrium, xerostomia, dysphagia, fungal and recurrent infections. The changes in nasal mucosa are not very well known. Only few papers concerned the problem. The main complaints of patients regarding the nose are xeromycteria, hyposmia and various degree of decreased patency of the nose. Chronic atrophic rhinitis, septal perforation, ulceration of nasal mucosa, alar necrosis, symptoms of staphylococcal or fungal infection can be found during otolaryngologic examination. The treatment in this group of patients should consist of systemic therapy of diabetes mellitus and on the other hand focal therapy with the use of a solution to moisten the nasal mucosa.

    2014-01-01

    Background Mutations in the EDAR-gene cause hypohidrotic ectodermal dysplasia, however, the oral phenotype has been described in a limited number of cases. The aim of the present study was to clinically describe individuals with the c.1072C > T mutation (p. Arg358X) in the EDAR gene with respect to dental signs and saliva secretion, symptoms from other ectodermal structures and to assess orofacial function. Methods Individuals in three families living in Sweden, where some members had a known c.1072C > T mutation in the EDAR gene with an autosomal dominant inheritance (AD), were included in a clinical investigation on oral signs and symptoms and self-reported symptoms from other ectodermal structures (n = 37). Confirmation of the c.1072C > T mutation in the EDAR gene were performed by genomic sequencing. Orofacial function was evaluated with NOT-S. Results The mutation was identified in 17 of 37 family members. The mean number of missing teeth due to agenesis was 10.3 ± 4.1, (range 4–17) in the mutation group and 0.1 ± 0.3, (range 0–1) in the non-mutation group (p  T mutation in the EDAR-gene displayed a typical pattern of congenitally missing teeth in the frontal area with functional consequences. They therefore have a need for special attention in dental care, both with reference to tooth agenesis and low salivary secretion with an increased risk for caries. Sweating problems were the most frequently reported symptom from other ectodermal structures. PMID:24884697

    Introduction The purpose of this study was to determine whether ligamentum flavum hypertrophy among disc herniated patients causes contralateral pain symptoms. For this reason we measured the thickness of the ligament in disc herniated patients with ipsilateral or contralateral symptoms. Material and methods Two hundred disc herniated patients with ipsilateral symptoms as group I were compared with five disc herniated patients with only contralateral symptoms as group II. Ligamenta flava thicknesses and spinal canal diameters of both groups were measured on magnetic resonance imaging (MRI) with a micro-caliper. Results Both groups underwent surgery only on the disc herniated side. The total thicknesses of the ligamenta flava in group II was thicker than in group I. There was no spinal stenosis in either group and no significance difference between the groups. Statistically significant differences were found for both ipsilateral and contralateral thickness of the ligament flava in both groups. We also compared thickness of the ligamenta flava for each level of disc herniation in group I; ligamenta flava hypertrophy was more common at L3-L4 and L4-L5 levels of vertebrae in females. Conclusions Aetiology of contralateral sciatica among disc herniated patients may be related to hypertrophy of the ligamenta flava, especially on the opposite side. Surgical approaches of the disc herniated side alone may be sufficient for a good outcome. PMID:22371809

    This study examined the effects of beta-hydroxyl-beta-methylbutyrate (HMB) and alpha-ketoisocaproic acid (KIC) supplementation on signs and symptoms of exercise-induced muscle damage following a single bout of eccentrically biased resistance exercise. Six non-resistance trained male subjects performed an exercise protocol designed to induce muscle damage on two separate occasions, performed on the dominant or non-dominant arm in a counter-balanced crossover design. Subjects were assigned to an HMB/KIC (3 g HMB and 0.3 g alpha-ketoisocaproic acid, daily) or placebo treatment for 14 d prior to exercise in the counter-balanced crossover design. One repetition maximum (1RM), plasma creatine kinase activity (CK), delayed onset muscle soreness (DOMS), limb girth, and range of motion (ROM) were determined pre-exercise, at 1h, 24 h, 48 h, and 72 h post-exercise. DOMS and the percentage changes in 1RM, limb girth, and ROM all changed over the 72 h period (P HMB//IC supplementation attenuated the CK response, the percentage decrement in 1RM, and the percentage increase in limb girth (P HMB/KIC treatment. In conclusion, 14 d of HMB and KIC supplementation reduced signs and symptoms of exercise-induced muscle damage in non-resistance trained males following a single bout of eccentrically biased resistance exercise.

    This study evaluates the influence of air humidification in aircraft on symptoms, tear-film stability, nasal patency, and peak expiratory flow. Commercial air crew (N=71) were given a medical examination during eight flights from Stockholm to Chicago and eight flights in the opposite direction. Examinations were done onboard one Boeing 767 aircraft equipped with an evaporation humidifier in the forward part of the cabin. The investigators followed the air crew, staying one night in Chicago and returning with the same crew. Four of the flights had the air humidification device active in-flight to Chicago and deactivated when returning to Stockholm. The other four flights had the inverse humidification sequence. The humidification sequence was randomized and double blind. Hygienic measurements were performed. The humidification increased the relative air humidity by 10% in the 1st row in business class, by 3% in the last row (39th row) in tourist class, and by 3% in the cockpit. Air humidification increased tear-film stability and nasal patency and decreased ocular, nasal, and dermal symptoms and headache. The mean concentration of viable bacteria [77-108 colony-forming units (cfu)/m(3)], viable molds (74-84 cfu/m(3)), and particulate matter (1-8 microg/m(3)) was low, both during the humidified and non-humidified flights. Relative air humidity is low (10-12%) during intercontinental flights and can be increased by the use of a ceramic evaporation humidifier, without any measurable increase of microorganisms in cabin air. Air humidification could increase passenger and crew comfort by increasing tear-film stability and nasal patency and reducing various symptoms.

    Full Text Available Abstract Background In a previous study of computer operators we have demonstrated the relation of upper limb pain to individual and patterns of neurological findings (reduced function of muscles, sensory deviations from normal and mechanical allodynia of nerve trunks. The identified patterns were in accordance with neural afflictions at three specific locations (brachial plexus at chord level, posterior interosseous and median nerve on elbow level. We have introduced an intervention program aiming to mobilize nerves at these locations and tested its efficacy. Methods 125 and 59, respectively, computer operators in two divisions of an engineering consultancy company were invited to answer a questionnaire on upper limb symptoms and to undergo a blinded neurological examination. Participants in one division were subsequently instructed to participate in an upper limb stretching course at least three times during workdays in a six month period. Subjects from the other division served as controls. At the end of the intervention both groups were invited to a second identical evaluation by questionnaire and physical examination. Symptoms and findings were studied in the right upper limb. Perceived changes of pain were recorded and individual and patterns of physical findings assessed for both groups at baseline and at follow-up. In subjects with no or minimal preceding pain we additionally studied the relation of incident pain to the summarized findings for parameters contained in the definition of nerve affliction at the three locations. Results Summarized pain was significantly reduced in the intervention group but unchanged in controls. After the intervention, fewer neurological abnormalities in accordance with nerve affliction were recorded for the whole material but no conclusion could be drawn regarding the relation to the intervention of this reduction. Incident pain correlated to findings in accordance with the three locations of nerve

    The aim of this study was to analyze and compare prevalence of signs and frequently occurring symptoms indicative of temporomandibular disorder (TMD) and headaches in 35-, 50-, 65- and 75-year-old men and women in Västerbotten County, Sweden. From a total target population of 11 324 subjects living in Västerbotten County in the year 2002, 300 individuals in each age group were randomly selected. Of these, 998 (82% response rate) answered and returned a postal questionnaire and 779 (65% response rate) individuals accepted a clinical examination. The prevalence of frequent TMD symptoms peaked among 50-year-old women and then declined. Women at this age reported significantly higher prevalence compared to men for all TMD symptoms except temporomandibular joint locking. In the 65- and 75-year-olds, the prevalence was practically equal between men and women as well as between these ages. Frequent headaches showed the highest prevalence among 35- and 50-year-old women, with a statistically significant difference between men and women of 50 years of age (p temporomandibular joint sounds (p headaches showed a similar pattern, with higher prevalence among the 35- and 50-year-old, as compared to the 65- and 75-year-old, participants.

    There is a lack of knowledge about the effectiveness of manual therapy (MT) on subjects with temporomandibular disorders (TMD). The aim of this systematic review is to synthetise evidence regarding the isolated effect of MT in improving maximum mouth opening (MMO) and pain in subjects with signs and symptoms of TMD. MEDLINE(®) , Cochrane, Web of Science, SciELO and EMBASE(™) electronic databases were consulted, searching for randomised controlled trials applying MT for TMD compared to other intervention, no intervention or placebo. Two authors independently extracted data, PEDro scale was used to assess risk of bias, and GRADE (Grading of Recommendations Assessment, Development and Evaluation) was applied to synthetise overall quality of the body of evidence. Treatment effect size was calculated for pain, MMO and pressure pain threshold (PPT). Eight trials were included, seven of high methodological quality. Myofascial release and massage techniques applied on the masticatory muscles are more effective than control (low to moderate evidence) but as effective as toxin botulinum injections (moderate evidence). Upper cervical spine thrust manipulation or mobilisation techniques are more effective than control (low to high evidence), while thoracic manipulations are not. There is moderate-to-high evidence that MT techniques protocols are effective. The methodological heterogeneity across trials protocols frequently contributed to decrease quality of evidence. In conclusion, there is widely varying evidence that MT improves pain, MMO and PPT in subjects with TMD signs and symptoms, depending on the technique. Further studies should consider using standardised evaluations and better study designs to strengthen clinical relevance. © 2015 John Wiley & Sons Ltd.

    Full Text Available Moyamoya disease is a rare neurological condition that affects children and adults of all ages. It is characterized by chronic, progressive stenosis of the circle of Willis that ultimately leads to the development of extensive collateral vessels. Presenting symptoms are usually due to cerebral ischemia or hemorrhage. The Japanese term moyamoya (meaning puffy or obscure was coined to describe the characteristic ‘smoke in the air’ appearance of these vessels on cerebral angiography. Moyamoya has the highest recorded incidence in Japan (0.28 per 100,000. In the west it is an extremely rare condition with an overall incidence of (0.086 per 100,000 in the Western United States. Etiology for the most part is unknown; however, genetic susceptibility related to RNF213 gene on chromosome 17q25.3 has been suggested. Moyamoya is being diagnosed more frequently in all races with varying clinical manifestations. Moyamoya disease is a rare progressive neurologic condition characterized by occlusion of the cerebral circulation with extensive collaterals recruitment in children and adults. Distinguished radiological findings confirm the diagnosis. Early recognition and swift institution of therapy is vital in order to minimize neurological deficits. We present the case of a 19-year-old African American female who presented with left-sided parastheia, weakness, and headache for 2 days duration.

    Lupus nephritis is one of the most serious complications of systemic lupus erythematosus (SLE). In the kidney, immune complexes and autoantibodies activate mesangial cells that secrete cytokines that can further amplify inflammatory processes. We present the case of a 42-year-old woman with lupus nephritis accompanied by periods of exacerbation of SLE, with necrotic-like skin lesions, psoriatic arthritis without skin psoriasis, purpura of the lower limb, petechial rash, joint pain, fever, eyelid edema with bilateral conjunctival hyperemia and itching. The patient underwent a dialytic treatment of hemodiafiltration with endogenous reinfusion. The technique uses the super-high-flux membrane Synclear 02 (SUPRA treatment) coupled with an adsorbent cartridge that has affinity for many toxins and mediators. Fever and joint pain were immediately reduced after treatment and, subsequently, there was a notable reduction of the skin damage. Prednisone and immunosuppressive drugs were gradually reduced until complete suspension. High-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer was performed for identification of proteins captured by a resin bed during a dialysis session of the patient. This technique identified several biomarkers of kidney injuries, uremic toxins, fragments of immunoglobulins, antigens involved in antiphospholipid syndrome and a new marker (α-defensin) that correlated significantly with disease activity. The removal of these different proteins could possibly provide an explanation of the improvement in the patient's symptoms and the normalization of her SLE. SUPRA coupled with an adsorption may be a promising new technique for the treatment of lupus nephritis.

    An analysis of 10-year experience of a radiological department (962 patients) indicated late admission of oral mucosa cancer patients for specialized treatment: 75-85% of the patients were admitted with Stage 2-4 disease. The assessment of the efficacy of radiotherapy according to the 3 ad 5-year survival rates showed that better results were obtained for buccal mucosa cancer and the worst for mouth fundus cancer. Regional metastates are a poor prognostic sign, particularly fixed metastases in patients with tongue and mouth fundus cancer. Combined therapy turned out be the most effective in tongue cancer. In different variants of dose delivery in time the most favorable results were obtained with small fractionation (a conventional course). However it should be noted that a split course was usually applied to weak elderly patients with advanced stages of disease

    Full Text Available Heterotopic gastric mucosa (HGM is occasionally found at endoscopy in the proximal esophagus of adults and children, when it manifests as an asymptomatic small island of reddish pink mucosa just below the upper esophageal sphincter. There are few reports of esophageal HGM detected by endoscopy after repair of esophageal atresia (EA with tracheo-esophageal fistula (TEF. We report a child with multiple patches of HGM in the proximal and distal esophagus seen at endoscopy after EA/TEF repair. No obvious symptoms were related to the HGM and she remains under endoscopic surveillance. The incidence of esophageal HGM may be increased in patients with EA and its distribution can be more extensive than a simple “inlet patch”. There is evidence to suggest that esophageal HGM increases the risk of developing Barrett's esophagus and has a malignant potential. Heterotopic gastric mucosa extends the spectrum of potential pathologies affecting the esophagus in patients with EA/TEF and supports current international guidelines for endoscopic surveillance of these patients.

    The concentrations in the intestinal mucosa after the initial dose of cefoxitin, piperacillin and clindamycin have been studied. The antibiotics were given at the induction of anesthesia as prophylaxis to patients undergoing elective colorectal surgery. The concentrations of the antibiotics in serum and intestinal mucosa taken during the operation were determined by the microbiological agar diffusion method. Therapeutic concentrations in intestinal mucosa were maintained during the major part of the operation period. The mean mucosa/serum concentration ratios were for cefoxitin 0.4, for piperacillin 0.5 and for clindamycin 1.2.

    The objective of the present study was to determine if there is correlation between signs of reflux laryngitis (RL) and reflux oesophagitis (RE) in patients with gastro-oesophageal reflux disease (GORD) symptoms. Laryngeal photography obtained from patients during oesophagogastroduodenoscopy were examined by two otolaryngologists experienced in the field of extra-oesophageal reflux regarding the presence and severity of RL. The presence of RE was evaluated by gastroenterologist. Smokers, heavy drinkers and patients with bronchial asthma were excluded from the statistical analysis. A total of 681 patients were analysed. RL was diagnosed in 367 (53.9%) cases, of whom 182 patients had mild, 118 moderate and 67 severe (Reflux Finding Score > 7) RL. RE was diagnosed in 103 (28.1%) patients with RL and in 80 (25.7%) patients without RL. Neither the difference between the overall group of patients with RL and those without (OR 1.141, 95% CI 0.811-1.605, p = 0.448), nor the differences between the respective subgroups of patients with mild, moderate and severe RL and those without RL were statistically significant. The OR and 95% CI for mild, moderate and severe RL were 1.042, 95% CI 0.712-1.526, p = 0.834, 1.182, 95% CI 0.764-1.831, p = 0.453 and 1.0, 95% CI 0.566-1.766, p = 0.999 respectively. It can be concluded that there is no correlation between RL and RE in patients with GORD symptoms. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    We investigated the prognostic utility of onset age at first signs and symptoms (SS) to predict onset age at loss of ambulation (LOA) for childhood-onset Duchenne and Becker Muscular Dystrophies (DBMD). Our cohort comprised male cases with DBMD ascertained by the population-based Muscular Dystrophy Surveillance, Tracking, and Research Network (MD STARnet). Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models for associations between onset ages of first SS and LOA. Covariates controlled for were corticosteroid use, family history of DBMD, birth year, race/ethnicity, and MD STARnet site. Onset age at first SS was considered as a continuous and as a categorical variable. A one-year increase in onset age at first SS was significantly associated with a 10% reduction in annual risk of LOA (HR = 0.90, CI = 0.87-0.94). Treating onset age at first SS as a categorical variable yielded a similar association (≥ 5 years: referent; ≥ 3 to Becker muscular dystrophies.

    Distinction between neuropathic pain and nociceptive pain helps facilitate appropriate management of pain; however, diagnosis of neuropathic pain remains a challenge. The aim of this study was to develop a Korean version of the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) pain scale and assess its reliability and validity. The translation and cross-cultural adaptation of the original LANSS pain scale into Korean was established according to the published guidelines. The Korean version of the LANSS pain scale was applied to a total of 213 patients who were expertly diagnosed with neuropathic (n = 113) or nociceptive pain (n = 100). The Korean version of the scale had good reliability (Cronbach's α coefficient = 0.815, Guttman split-half coefficient = 0.800). The area under the receiver operating characteristic curve was 0.928 with a 95% confidence interval of 0.885-0.959 (P < 0.001), suggesting good discriminate value. With a cut-off score ≥ 12, sensitivity was 72.6%, specificity was 98.0%, and the positive and negative predictive values were 98% and 76%, respectively. The Korean version of the LANSS pain scale is a useful, reliable, and valid instrument for screening neuropathic pain from nociceptive pain. PMID:26339176

    Chronic pain is a well-known phenomenon. The differential diagnosis between neuropathic and nociceptive pain syndromes is a challenge. Consequently, assessment instruments that can distinguish between these conditions in a standardized way are of the utmost importance. The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) is a screening tool developed to identify chronic neuropathic pain. The aim of this study was the Portuguese language translation, linguistic adaptation of the LANSS pain scale, its semantic validation, internal consistency, temporal stability, as well its validity and discriminative power. LANSS Portuguese version scale was applied to 165 consecutive patients attending the pain clinic: 103 fulfilled the clinical criteria for the diagnosis of pain of neuropathic origin and the remaining 62 fulfilled the criteria for nociceptive pain. The scale proved to be an internally consistent (Cronbach's alpha = 0.78) and reliable instrument with good test-retest stability (r = 0.7; P cross-cultural version is a reliable and valid instrument for the differentiation of this type of pain.

    The effect of xylometazolin spray (OTRIVEN) on the nasal mucosa was tested on persons with and without clinical signs of rhinitis and sinusitis. MRI is an excellent means to show the decongestive effect. The reaction is chiefly seen at the inferior and middle nasal concha and becomes manifest in a few minutes. No significant effect is noticeable at the maxillary sinus mucosa and infiltrated ethmoidal sinus. Generally, it is possible to show and examine the pharmacological effects that change the size and the liquid consistency of organs. (orig.) [de

    The self-administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS) scale is a tool designed to identify patients with pain with neuropathic features. To assess the validity and reliability of the Spanish-language version of the S-LANSS scale. Our study included a total of 182 patients with chronic pain to assess the convergent and discriminant validity of the S-LANSS; the sample was increased to 321 patients to evaluate construct validity and reliability. The validated Spanish-language version of the ID-Pain questionnaire was used as the criterion variable. All participants completed the ID-Pain, the S-LANSS, and the Numerical Rating Scale for pain. Discriminant validity was evaluated by analysing sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC). Construct validity was assessed with factor analysis and by comparing the odds ratio of each S-LANSS item to the total score. Convergent validity and reliability were evaluated with Pearson's r and Cronbach's alpha, respectively. The optimal cut-off point for S-LANSS was ≥12 points (AUC=.89; sensitivity=88.7; specificity=76.6). Factor analysis yielded one factor; furthermore, all items contributed significantly to the positive total score on the S-LANSS (P<.05). The S-LANSS showed a significant correlation with ID-Pain (r=.734, α=.71). The Spanish-language version of the S-LANSS is valid and reliable for identifying patients with chronic pain with neuropathic features. Copyright © 2016 Sociedad Española de Neurología.

    To estimate the cost of functional gastrointestinal disorders (FGIDs) and related signs and symptoms in infants to the third party payer and to parents. To estimate the cost of illness (COI) of infant FGIDs, a two-stage process was applied: a systematic literature review and a COI calculation. As no pertinent papers were found in the systematic literature review, a 'de novo' analysis was performed. For the latter, the potential costs for the third party payer (the National Health Service (NHS) in England) and for parents/carers for the treatment of FGIDs in infants were calculated, by using publicly available data. In constructing the calculation, estimates and assumptions (where necessary) were chosen to provide a lower bound (minimum) of the potential overall cost. In doing so, the interpretation of the calculation is that the true COI can be no lower than that estimated. Our calculation estimated that the total costs of treating FGIDs in infants in England were at least £72.3 million per year in 2014/2015 of which £49.1 million was NHS expenditure on prescriptions, community care and hospital treatment. Parents incurred £23.2 million in costs through purchase of over the counter remedies. The total cost presented here is likely to be a significant underestimate as only lower bound estimates were used where applicable, and for example, costs of alternative therapies, inpatient treatments or diagnostic tests, and time off work by parents could not be adequately estimated and were omitted from the calculation. The number and kind of prescribed products and products sold over the counter to treat FGIDs suggest that there are gaps between treatment guidelines, which emphasise parental reassurance and nutritional advice, and their implementation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    We aimed to assess the diagnostic utility of the linguistically validated Japanese version of the Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale (LANSS-J) as a screening tool for neuropathic pain in the clinical setting. Patients with neuropathic pain or nociceptive pain who were 20 to 85 years of age were included. Sensitivity and specificity using the original cutoff value of 12 were assessed to evaluate the diagnostic utility of the LANSS-J. Sensitivity and specificity with possible cutoff values were calculated, along with area under the receiver operating characteristic curve. We then evaluated agreement regarding assessment of the LANSS-J by two investigators. We used the intraclass correlation coefficient (ICC) for the total score and Cohen's kappa coefficient for each item. Data for patients with neuropathic pain (n = 30) and those with nociceptive pain (n = 29) were analyzed. With a cutoff of 12, the sensitivity was 63.3% (19/30) and the specificity 93.1% (27/29). Sensitivity improved substantially with a cutoff of ≤ 11 (≥ 83.3%, 25/30). High specificity (93.1%, 27/29) was sustained with a cutoff of 9 to 12. The ICC for the total score was 0.85, indicating sufficient agreement. Kappa coefficients ranged from 0.68 to 0.84. The LANSS-J is a valid screening tool for detecting neuropathic pain. Our results suggest that employing the original cutoff value provides high specificity, although a lower cutoff value of 10 or 11 (with its high specificity maintained) may be more beneficial when pain attributed to neuropathic mechanisms is suspected in Japanese patients. © 2016 World Institute of Pain.

    Schools may be poorly ventilated and may contain furry pet allergens, particles and microorganisms. We studied health effects when changing from mixing ceiling ventilation to two types of displacement ventilation, front ventilation system (FVS) and floor master system (FMS). The study included pupils in three elementary school classes (N = 61), all with floor heating. One class received blinded interventions; the two others were unchanged (controls). Ventilation flow and supply air temperature was kept constant. The medical investigation included tear film stability (BUT), nasal patency and a questionnaire containing rating scales. When changing from mixing ventilation to FVS, the pupils (N = 26) perceived better air quality (P = 0.006) and less dyspnoea (P = 0.007) as compared to controls (N = 35), and BUT was improved (P = 0.03). At desk level, mean CO(2) was reduced from 867 to 655 ppm. Formaldehyde and viable bacteria were numerically lower, while total bacteria and molds were higher with displacement ventilation. There was no difference in symptoms or signs when changing from FVS to FMS. Cat (Der p1), dog (Can f1) and horse allergen (Equ cx) were common in air at all conditions. In conclusion, displacement ventilation may have certain positive health effects among pupils, as compared to conventional mixing ceiling systems. Displacement ventilation may be a suitable ventilation principle for achieving good indoor environment in classrooms. The type of supply air diffuser does not seem to be of major importance. The combination of floor heating and displacement ventilation can be a useful way of avoiding the previously described problem of thermal discomfort. © 2011 John Wiley & Sons A/S.

    Full Text Available Objective: The Self-administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS is a 7-item self-report scale developed to identify pain which is of predominantly neuropathic origin. The aim of this study was to develop a Malayalam version of the LANSS and to test its validity and reliability in chronic pain patients. Methodology: We enrolled 101 Malayalam-speaking chronic pain patients who visited the Division of Palliative Medicine, Regional Cancer Centre, Thiruvananthapuram, Kerala, India. The translated version of S- LANSS was constructed by standard means. Fifty-one neuropathic pain and fifty nociceptive pain patients were identified by an independent pain physician and were subjected to the new pain scale by a palliative care nurse who was blinded to the diagnosis. The “gold standard diagnosis” is what the physician makes after clinical examination. Its validation, sensitivity, specificity, and positive and negative predictive values were determined. Results: Fifty-one neuropathic pain and fifty nociceptive pain patients were subjected to the Malayalam version of S-LANSS pain scale for validity testing. The agreement by Cohen's Kappa 0.743, Chi-square test P < 0.001, sensitivity 89.58, specificity 84.91, positive predictive value 84.31, negative predictive value 90.00, accuracy by 87.13, and likelihood ratio 5.94. Conclusion: The Malayalam version of S-LANSS pain scale is a validated screening tool for identifying neuropathic pain in chronic pain patients in Malayalam-speaking regions.

    Chronic granulomatous disease (CGD) is a rare inherited disorder in which phagocytes are unable to eradicate pathogens because of a deficit of nicotinamide adenine dinucleotide phosphate oxidase. Among CGD patients, ∼ 30% to 50% develop severe gastrointestinal tract symptoms. Although characteristic histologic findings of CGD-associated colitis have been reported, information on endoscopic features remained vague. A total of 8 male patients with CGD (ages 2-23 years) from 2 Japanese institutions underwent colonoscopy for the evaluation of their fever, diarrhea, bloody stool, and abdominal pain. The endoscopic and histologic findings were retrospectively reviewed. The endoscopic findings of CGD-associated colitis appeared varied. Notably, brownish dots over a yellowish edematous mucosa were observed in 3 of the 8 patients. Prominent pigment-laden macrophages were noted histologically on the mucosa. Although nonspecific endoscopic findings of CGD-associated colitis have been reported before, our observation of brownish dots spread across a yellowish edematous mucosa, termed "leopard sign," could be a unique feature of this condition.

    Species and quantitative characteristics of upper respiratory tract (URT) mucosa microflora in women at gestation period. The results of a bacteriological study of 68 samples of mucus from posterior pharyngeal wall in women at gestation period (from 14 weeks), 52 of those--from pregnant women with acute respiratory infection (ARI) symptoms and 16--from women without signs of disease, are presented. Qualitative and quantitative composition of microflora was studied by a generally accepted bacteriological method. During primary bacteriological study 111 microorganism cultures were isolated. 88 (79.3%) of strains belonged to Gram-positive flora, 20 (18.0%)--to Gram-negative, and Candida genus fungi constituted 3 (2.7%) isolates. Streptococcus pyogenes and Moraxella catarrhalis were isolated from pregnant women with ARI signs at 23.1% and 5.8% frequency of occurrence, respectively. A higher detectability of Staphylococcus aureus--in 31.3% and Candida spp.--in 6.3% of women who did not complain as opposed to patients with URT lesions (in 21.2 and 3.9%, respectively) was determined. In patients without ARI signs the amount of bacteria did not exceed 10(5)--10(6) CFU/ml, in pregnant women with ARI diagnosis in 8 of 52 cases semination of pharyngeal mucuswas observed--10(7)--10(8) CFU/ml. Prevalence of S. aureus, Streptococcus agalactiae, S. pyogenes, Streptococcus mutans in composition of pharyngeal mucus microflora of pregnant women both with URT lesion signs and without them was shown, however the degree of semination by pathogens in the groups was different that determined the severity of disease manifestations.

    Full Text Available In order to investigate how holmium laser enucleation of the prostate (HoLEP improves urinary storage symptoms, we assessed blood flow in the urinary bladder mucosa of patients with benign prostatic hyperplasia (BPH before and after laser surgery. Seventy-four consecutive patients with BPH (median age 69 years, range; 53-88 underwent HoLEP at our institution and are included in this study. We prospectively assessed the International Prostate Symptom Score (IPSS, IPSS-QOL Score, the Overactive Bladder Symptom Score (OABSS, uroflowmetry, and blood flow in the urinary bladder, before and after surgery. Blood flow in the bladder mucosa was measured using the OMEGA FLOW (OMEGAWAVE, Tokyo, Japan laser Doppler flowmeter. The median volume of the enucleated adenomas was 45.0 g (range: 25.0 to 83.2. The median IPSS improved significantly from 20 (range: 6-35 to 3 (0-22 (p < 0.001; Wilcoxon signed-rank test, as did the storage symptoms score, which decreased from 13 (2-20 to 3 (1-8 (p < 0.001. Median bladder blood flow increased at the trigone from 9.57 ± 0.83 ml/sec to 17.60 ± 1.08 ml/sec. Multiple regression analysis for the improved storage symptom score eliminated all explanatory variables except increased bladder perfusion. The data suggest that HoLEP improves blood flow in the bladder mucosa, which independently leads to the improvement of storage symptoms.

    Full Text Available Both immunologic and nonimmunologic drug reactions can be seen in oral mucosa. Since considerable number of these reactions heals spontaneously without being noticed by the patients, exact frequency of the lesions is unknown. Most common lesions are xerostomia, taste disorders, mucosal ulcerations and edema. In this article, oral lesions resulting from drug intake similar to those from oral lesions of local and systemic diseases, and diagnostic problems caused by these similarities, have been reviewed.

    Urethral strictures can occur on the basis of trauma, infections, iatrogenic-induced or idiopathic and have a great influence on the patient's quality of life. The current prevalence rate of male urethral strictures is 0.6% in industrialized western countries. The favored form of treatment has experienced a transition from less invasive interventions, such as urethrotomy or urethral dilatation, to more complex open surgical reconstruction. Excision and primary end-to-end anastomosis and buccal mucosa graft urethroplasty are the most frequently applied interventions with success rates of more than 80%. Risk factors for stricture recurrence after urethroplasty are penile stricture location, the length of the stricture (>4 cm) and prior repeated endoscopic therapy attempts. Radiation-induced urethral strictures also have a worse outcome. There are various therapy options in the case of stricture recurrence after a failed urethroplasty. In the case of short stricture recurrences, direct vision urethrotomy shows success rates of approximately 60%. In cases of longer or more complex stricture recurrences, redo urethroplasty should be the therapy of choice. Success rates are higher than after urethrotomy and almost comparable to those of primary urethroplasty. Patient satisfaction after redo urethroplasty is high. Primary buccal mucosa grafting involves a certain rate of oral morbidity. In cases of a redo urethroplasty with repeated buccal mucosa grafting, oral complications are only slightly higher.

    Celiac Disease (CD) is an immune reaction to gluten containing foods such as rye, wheat and barley. This condition affects individuals with a genetic predisposition; it targets the small bowel and may cause symptoms including diarrhea, malabsorption, weight loss, abdominal pain and bloating. The diagnosis is made by serologic testing of celiac-specific antibodies and confirmed by histology. Certain endoscopic characteristics, such as scalloping, reduction in the number of folds, mosaic-pattern mucosa or nodular mucosa, are suggestive of CD and can be visualized under white light endoscopy. Due to its low sensitivity, endoscopy alone is not recommended to diagnose CD; however, enhanced visual identification of suspected mucosal abnormalities through the use of new technologies, such as narrow band imaging with magnification (NBI-ME), could assist in targeting biopsies and thereby increasing the sensitivity of endoscopy. This is a case series of seven patients with serologic and histologic diagnoses of CD who underwent upper endoscopies with NBI-ME imaging technology as part of their CD evaluation. By employing this imaging technology, we could identify patchy atrophy sites in a mosaic pattern, with flattened villi and alteration of the central capillaries of the duodenal mucosa. We refer to this epithelial pattern as "Leopard Skin Sign". Since epithelial lesions are easily seen using NBI-ME, we found it beneficial for identifying and targeting biopsy sites. Larger prospective studies are warranted to confirm our findings.

    To determine whether ocular phenotypic features of keratoconjunctivitis sicca (KCS) and/or participant-reported symptoms of dry eye disease are associated with depression in women participants enrolled in the Sjögren's International Collaborative Clinical Alliance (SICCA). Cross-sectional study. Women enrolled in the SICCA registry from 9 international research sites. Participants met at least 1 of 5 inclusion criteria for registry enrollment (including complaints of dry eyes or dry mouth, a previous diagnosis of Sjögren syndrome (SS), abnormal serology (positive anti-Sjögren syndrome antigen A and/or B [anti-SSA and/or anti-SSB]), or elevated antinuclear antibody and rheumatoid factor), bilateral parotid gland enlargement, or multiple dental caries). At baseline, participants had oral, ocular, and rheumatologic examination; blood and saliva collection; and a labial salivary gland biopsy (LSGB). They also completed an interview and questionnaires including assessment of depression with the Patient Health Questionnaire 9 (PHQ-9). Univariate logistic regression was used to assess the association between depression and demographic characteristics, participant-reported health, phenotypic features of Sjögren syndrome, and participant-reported symptoms. Mixed-effects modeling was performed to determine if phenotypic features of KCS and/or participant-reported symptoms of dry eye disease were associated with depression, controlling for health, age, country or residence, and sex and allowing for nonindependence within geographic site. Dry eye complaints produced a 1.82-fold (95% confidence interval [CI] 1.38-2.40) higher odds of having depression compared to being symptom-free (P dry eyes and/or dry mouth rather than SS itself resulted in higher odds of depression. One particular ocular phenotypic feature of SS, a positive ocular staining score, was inversely correlated with depression. Participant-reported eye symptoms, particularly specific ocular sensations such as

    Telomere length in human somatic cells gradually decreases with the number of cell divisions and is regarded as a marker of somatic cell turnover. Mucosal cells of the affected colon show rapid turnover in individuals with active ulcerative colitis (UC). Telomere length was determined by Southern blot analysis of terminal restriction fragments (TRFs) from the colonic mucosa of 17 patients with UC in remission, two of whom showed dysplasia, and 17 control subjects without colitis. For each individual, mean TRF length was compared between rectal mucosa and unaffected cecal mucosa. The mean TRF length of the rectal mucosa was significantly less than that of cecal mucosa in UC patients (7.87 +/- 0.36kb versus 8.77 +/- 0.21 kb; P = 0.0015, Wilcoxon signed rank test), whereas no significant difference was detected in the control subjects. The extent of telomere shortening was 10.6 +/- 3.35% in UC patients, compared with 0.8 +/- 0.64% in noncolitis controls (P = 0.0024, Mann-Whitney U-test). Four UC patients, two of whom had dysplasia, showed telomere shortening of more than 20% in the rectal mucosa. These observations suggest that telomere shortening in the colonic mucosa of individuals with UC may represent the history of mucosal inflammation during disease of long duration, and that it may contribute to aneuploidy in UC.

    To compare gut bacterial diversity and amount of Enterobacteriaceae in colonic mucosa between patients with and without diverticular disease (DD). Patients in a stable clinical condition with planned elective colonoscopy were included. Blood samples and colon mucosa biopsies were collected at the colonoscopy. Study questionnaires including questions about gastrointestinal symptoms were completed by the patients and physicians. DNA from mucosa samples was isolated and the amount of Enterobacteriaceae was estimated using PCR assay. Terminal restriction fragment length polymorphism was applied to assess microbial diversity. Diversity was estimated by calculations of richness (number of terminal restriction fragments) and Shannon-Wiener and Simpson's indices. A total of 51 patients were included, 16 patients with DD [68 (62-76) years] and 35 controls [62 (40-74) years] without any diverticula. Patients with DD had significantly higher levels of Enterobacteriaceae than those without DD ( P = 0.043), and there was an inverse relationship between the amount of Enterobacteriaceae and the Simpson's index (rs = -0.361, P = 0.033) and the Shannon-Wiener index (rs = -0.299, P = 0.081). The Simpson's index ( P = 0.383), Shannon-Wiener index ( P = 0.401) or number of restrictions fragments ( P = 0.776) did not differ between DD and controls. The majority of patients experienced gastrointestinal symptoms, and 22 patients (43.1%) fulfilled the criteria for irritable bowel syndrome, with no difference between the groups ( P = 0.212). Demography, socioeconomic status, lifestyle habits, inflammatory biomarkers, or symptoms were not related to the amount of Enterobacteriaceae or bacterial diversity. Patients with DD had higher amount of Enterobacteriaceae in the colon mucosa compared to patients without diverticula.

A total of 55 cohorts totaling 2,268 pods of 3-10 cm length, one to two months of age, were tagged weekly. Pods were assessed throughout their lifetime, every one or two weeks, and classified in 3 different categories: healthy, diseased with no sporulation, diseased with sporulating lesions. As a first step, we used Generalized Linear Mixed Models (GLMM to determine with no a priori the period (when and for how long each climatic variable was better related with the appearance of symptoms and sporulation. Then the significance of the candidate variables was tested in a complete GLMM. Daily average wetness frequency from day 14 to day 1, before tagging, and daily average maximum temperature from day 4 to day 21, after tagging, were the most explanatory variables of the symptoms appearance. The former was positively linked with the symptoms appearance when the latter exhibited a maximum at 30°C. The most important variables influencing sporulation were daily average minimum temperature from day 35 to day 58 and daily average maximum temperature from day 37 to day 48, both after tagging. Minimum temperature was negatively linked with the sporulation while maximum temperature was positively linked. Results indicated that the fungal microclimatic requirements vary from the early to the late cycle stages, possibly due to the pathogen's long latent period. This

  11. Localization of ectopic gastric mucosa by scintigraphy

    D'Alonzo, W.A. Jr.

    1988-01-01

    When gastric mucosal tissue occurs outside of the confines of the stomach, it is termed ectopic or heterotopic. Ectopic gastric mucosa may be found within Meckel's diverticulum, duplications of the alimentary tract, and Barrett's esophagus. In addition, a surgeon may inadvertently leave behind antral gastric mucosa while performing a partial gastrectomy for peptic ulcer disease (i.e., retained gastric antrum). It is important to detect the presence and location of ectopic mucosa because acid and pepsin secretion may cause ulceration in the adjacent tissue resulting in serious complications. The only currently available specific diagnostic technique for detecting ectopic gastric mucosa is pertechnetate Tc 99m (TcO 4- ) scintigraphy. This chapter reviews the functional anatomy of gastric mucosa, the mechanism of TcO 4 - localization, the various entities containing ectopic gastric mucosa, and the methods and results of TcO 4 - scanning for these disorders

    Conclusion: The study demonstrates that oral mucosa alterations accompanying oral candidosis are a sensitive indicator of ID. All oral changes can be successfully ameliorated by iron therapy plus antifungals when candidosis exists. Investigating the origin of IDA is necessary, because it may be the first sign of a more serious disease, particularly malignancy.

    Our objective was a prospective comparison of MR enteroclysis (MRE) with multidetector spiral-CT enteroclysis (MSCTE). Fifty patients with various suspected small bowel diseases were investigated by MSCTE and MRE. The MSCTE was performed using slices of 2.5 mm, immediately followed by MRE, obtaining T1- and T2-weighted sequences, including gadolinium-enhanced acquisition with fat saturation. Three radiologists independently evaluated MSCTE and MRE searching for 12 pathological signs. Interobserver agreement was calculated. Sensitivities and specificities resulted from comparison with pathological results (n=29) and patient's clinical evolution (n=21). Most pathological signs, such as bowel wall thickening (BWT), bowel wall enhancement (BWE) and lymphadenopathy (ADP), showed better interobserver agreement on MSCTE than on MRE (BWT: 0.65 vs 0.48; BWE: 0.51 vs 0.37; ADP: 0.52 vs 0.15). Sensitivity of MSCTE was higher than that of MRE in detecting BWT (88.9 vs 60%), BWE (78.6 vs 55.5%) and ADP (63.8 vs 14.3%). Wilcoxon signed-rank test revealed significantly better sensitivity of MSCTE than that of MRE for each observer (p=0.028, p=0.046, p=0.028, respectively). Taking the given study design into account, MSCTE provides better sensitivity in detecting lesions of the small bowel than MRE, with higher interobserver agreement. (orig.)

    To identify associations between clinical symptoms of temporomandibular joint disorders and radiographic findings. Two hundred four adult patients (156 women, 48 men, mean age 40 years) with temporomandibular joint (TMJ) pain/sounds or changes in mandibular motion were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Bilateral sagittal corrected TMJ tomograms in closed and open positions were assessed for the presence of flattening, erosion, osteophytes, and sclerosis in the joint components and the range of mandibular motion. Logistic regression analyses were performed with the radiographic findings as the dependent variables and the following clinical variables as independent variables: opening pattern, maximal jaw opening, TMJ sounds, number of painful muscle/TMJ sites, duration of pain, presence of arthritic disease, depression and somatization scores, graded chronic pain, and age and gender. Coarse crepitus on opening/closing (odds ratio [OR] > or = 3.12), on lateral excursions (odds ratio > or = 4.06), and on protrusion (OR > or = 5.30) was associated with increased risk of degenerative findings in tomograms. A clinical diagnosis of osteoarthritis increased the risk of radiographic findings (OR > or = 2.95) and so did increasing age (OR > or = 1.03 per year) and the female gender (OR > or = 2.36). Maximal assisted opening and maximal opening without pain (position (OR > or = 2.60). No other significant associations were observed. Age, gender, and coarse crepitus, but no pain-related variables, were associated with increased risk of degenerative findings in TMJ tomograms. Maximal opening < 40 mm was associated with a posterior condyle-to-articular tubercle relation on opening.

    In 53 patients showing the clinical signs and symptoms of mitral valve prolapse (MVP) where coronary heart disease (CHD) had previously been excluded by angiography the myocardial metabolism of fatty acids was examined at rest using metabolic myocardial scintigraphy (MMS) and 123-I-ω-HDA as tracer substance. The results were correlated with those obtained by other methods of investigation (findings at rest and during exercise from ECG recordings, tests using a flow-guided catheter and radionuclide ventriculography, further from echocardiography as well as myocardial Tl redistribution scintiscanning during exercise). For purposes of reference, MMS was additionally carried out in twelve normal individuals subjected to coronary angiography to exclude both MVP and CHD. The results of this study would appear to suggest that the pathological findings revealed by myocardial Tl scintigraphy in patients showing symptoms of MVP cannot invariably be classified as 'false' but are at least to some extent attributable to impaired myocardial perfusion, vitality or metabolism.

    There is a paucity of cross-cultural studies of behavioral and psychological symptoms of dementia (BPSD). BPSD were examined in a consecutive series of referrals to a psychogeriatric service in the United Kingdom (U.K.) and in Korea, using the BEHAVE-AD, the Cornell Scale for Depression in Dementia and the Mini-mental State Examination (MMSE). The U.K. service served a well-defined geographical catchment area with a multidisciplinary team and emphasis on home assessments. The Korean service was a nationwide service with limited community resources. The correlates of individual BPSD in each country and the differences between the two countries were examined. Koreans were younger, were more likely to be married, less likely to be single, had a greater number of people in their household and were more likely to live in their own homes than the U.K. sample. Koreans were more likely to be referred by general psychiatrists or family members, and the U.K. sample was more likely to be referred by general practitioners. Koreans were more likely to have Alzheimer's disease and the U.K. sample to have vascular dementia. The Korean sample had a lower MMSE score than the U.K. sample. In both countries, the total BEHAVE-AD score and most subscale scores were negatively correlated with the MMSE score. The total BEHAVE-AD score and all subscale scores were higher in the Korean sample than in the U.K. sample. The prevalence of all BPSD measured with the BEHAVE-AD were higher in the Korean sample (except aggressivity). These differences may be explained by differing interpretation and administration of the measurement instruments, models of service delivery, availability of primary and secondary care services, health seeking behavior of patients and families, cultural influences, and knowledge, expectations and recognition of BPSD by professionals in primary and secondary care. However, despite this, there was possible evidence of genuine differences worthy of further cross

    Objective: To determine the presence of Helicobacter pylori (H. pylori) in dental plaque of individuals suffering from H. pylori associated gastric disease. Patients and Methods: Patients presenting with symptoms/signs of chronic gastritis were included in the study. Specimens of dental plaque and gastric biopsy were collected from all the patients. The dental plaque specimen was processed for helicourease test and the gastric biopsy specimens were processed both for the helicourease test and histopathology. Results: Out of all patients studied (n=52), 32 (61.53%) were positive for helicourease test with gastric biopsy while 48 (92.30%) were positive with dental plaque. The histopathology of gastric biopsy showed H. pylori associated chronic active gastritis in 42 (80.76%) patients. Eight (15.38%) patients showed chronic active gastritis which was not associated with H. pylori while in 2 (3.84%) patients the gastric biopsy specimen was unremarkable. Conclusion: Majority of the patients have possible H. pylori colonization in dental plaque while about two-thirds have H. pylori associated chronic active gastritis. Oral cavity may be the first place for colonization and then the infection involves the gastric mucosa. (author)

    Temporomandibular disorder (TDM) is the most common source of orofacial pain of a non-dental origin. Sleep bruxism is characterized by clenching and/or grinding the teeth during sleep and is involved in the perpetuation of TMD. The aim of the present study was to investigate the effects of massage therapy, conventional occlusal splint therapy and silicone occlusal splint therapy on electromyographic activity in the masseter and anterior temporal muscles and the intensity of signs and symptoms in individuals with severe TMD and sleep bruxism. Sixty individuals with severe TMD and sleep bruxism were randomly distributed into four treatment groups: 1) massage group, 2) conventional occlusal splint group, 3) massage + conventional occlusal splint group and 4) silicone occlusal splint group. Block randomization was employed and sealed opaque envelopes were used to conceal the allocation. Groups 2, 3 and 4 wore an occlusal splint for four weeks. Groups 1 and 3 received three weekly massage sessions for four weeks. All groups were evaluated before and after treatment through electromyographic analysis of the masseter and anterior temporal muscles and the Fonseca Patient History Index. The Wilcoxon test was used to compare the effects of the different treatments and repeated-measures ANOVA was used to determine the intensity of TMD. The inter-group analysis of variance revealed no statistically significant differences in median frequency among the groups prior to treatment. In the intra-group analysis, no statistically significant differences were found between pre-treatment and post-treatment evaluations in any of the groups. Group 3 demonstrated a greater improvement in the intensity of TMD in comparison to the other groups. Massage therapy and the use of an occlusal splint had no significant influence on electromyographic activity of the masseter or anterior temporal muscles. However, the combination of therapies led to a reduction in the intensity of signs and

    Lung cancer is the one of the most common cause of cancer mortality among men in India where incidence rates are increasing although they are largely preventable diseases. In India, late presentation is generally responsible for high mortality and morbidity rates and early detection is one of the best ways to control it. The purpose of this study is to measure the level of awareness on lung cancer among women represented by a sample of college teachers in India and the impact of awareness programs in changing or adopting safer practices and the prevention and early detection of the disease. The assessment was conducted during a Pink Chain Campaign on cancer awareness in 2011 in various women colleges in India. Pre-test related to lung cancer was followed by awareness programs. Posttest using the same questionnaire was conducted at the end of interactive session, at 1 year and 6 months. A total of 156 out of 182 teachers participated in the study (overall response rate was 85.7%). Mean age of the study population was 42.4 years (range- 28-59 yrs). There was a significant increase in level of knowledge regarding lung cancer at 6 months and this was sustained at 1 year. Magazines and newspapers were the primary source for information regarding risk factors, signs and symptoms of lung cancer in more than 60% of teachers whereas more than 30% teachers were educated by doctors. At post-awareness after 1 year and 6 months, there was a significant change in alcohol and smoking habits. The main reasons for not undergoing screening tests are: ignorance (50%), lethargic attitude (44.8 %) and lack of time (34.6 %). Knowledge about lung cancer was very low among teachers. Overall awareness of risk factors, signs and symptoms, and screening modalities of lung cancer have improved after 1 year along with practices related to smoking and alcohol consumption. There was a significant improvement in people undergoing regular check-up's. Improved means of communication, access to

Cases were generated using either the Medical Treatment Protocols for Radiation Accident Victims (METREPOL, n = 167) system or using real-case descriptions extracted from a database system for evaluation and archiving of radiation accidents based on case histories (SEARCH, n = 24). The cases ranged from unexposed [response category 0 (RC 0, n = 89)] to mild (RC 1, n = 45), moderate (RC 2, n = 19), severe (RC 3, n = 20), and lethal (RC 4, n = 18) acute radiation syndrome. During the previous exercise, expert teams successfully predicted hematological acute radiation syndrome severity, determined whether hospitalization was required, and gave treatment recommendations, taking advantage of different software tools developed by the North Atlantic Treaty Organization teams. The authors provided the same data set to radiobiology students who were introduced to the medical management of acute effects after radiation exposure and the software tools during a class lasting 15 h. Corresponding to the previous results, difficulties in the discrimination between RC 0/RC 1 and RC 3/RC 4, as well as a systematic underestimation of RC 1 and RC 2, were observed. Nevertheless, after merging reported response categories into clinically relevant groups (RC 0-1, RC 2-3, and RC 3-4), it was found that the majority of cases (95.2% ± 2.2 standard deviations) were correctly identified and that 94.7% (±2.6 standard deviations) developing acute radiation syndrome and z96.4% (±1.6 standard deviations) requiring hospitalization were identified correctly. Two out of three student teams also provided a dose estimate. These results are comparable to the best-performing team of the 2015 North Atlantic Treaty Organization exercise (response category: 92.5%; acute

    Sixteen patients with cancer of the vagina that were controlled locally for a minimum of eighteen months after teletherpay (T) or brachytherapy (B) or both (T and B), were analyzed for radiation tolerance of the vaginal mucosa. The site of vaginal necrosis did not always coincide with the site of the tumor. The posterior wall appeared more vulnerable than the anterior or lateral walls. For the distal vaginal mucosa, necrosis requiring surgical intervention occurred following combined T and B, if summated rad exceeded9800. The upper vagina tolerated higher dosages. No patient surgery for upper vaginal necrosis even though summated (T and B) dosage up to 14,000 rad was applied. Placing radioactive needles on the surface of the vaginal cylinder with or without interstitial perincal needles should be avoided. Further accumulation of data is needed to define these vaginal mucosa tolerance limits more closely

    We studied 30 patients. 20 were males and 10 females. Mean age was 48 year old. Esophageal disease was not present neither gastro-esophageal reflux. Biopsy was taken between 24 hours and 25 days after nasogastric tube (NG) was put into place. Endoscopic findings were: hyperemic mucosa, submucosal hemorrhage, clots, erosions and ulcers near Esophago-gastric junction. Intraepithelial edema, vessel congestion, polymorphonuclear infiltration, fibrin thrombosis of submucosal vessels, ischemia, epithelial regeneration and ulcer were common histologic findings. All endoscopic and histologic alterations were related to the length of time of NG tube contact with the esophageal mucosa. We concluded that NG tube damages the esophageal mucosa by two mechanisms: a) Local irritation that favors b) gastric reflux by decreasing lower esophageal sphincter pressure.

    Recently, many details of the interplay between tumor cells and tumor-associated stromal elements leading to the progression of malignant disease were elucidated. In contrast, little is known about the role of uninvolved stromal tissue in the remote surrounding of the malignant tumor. Therefore, we performed a computer-aided morphometric study of rectal mucosa in samples taken 10 cm and 20 cm away from the malignant tumor during endoscopic examination of 23 patients older than 60 years. The samples of rectal mucosa from 10 healthy persons of corresponding age subjected to diagnostic rectoscopy during active screening for asymptomatic cancer were used as control. All structural elements of the rectal mucosa were studied and the number of nucleated cells in the lamina propria per 0.1 mm² of tissue was assessed. Our study revealed a reduced number of cells in the lamina propria of the rectal mucosa 10 cm and 20 cm away from the tumor lesion in both male and female patients. The decreased mucosal height and increased crypt number were registered in female patients 10 cm away from the tumor. The connective tissue of lamina propria showed a disorderly organization: the collagen fibers were frail, loosely arranged and signs of tissue edema were present. Small blood vessels and capillaries were much more frequently seen than in healthy tissue. Our results demonstrate the complex interactions between the cancer and remote mucosal tissue of the affected organ.

    To describe the presence of heterotopic gastric mucosa forming an abscess associated with acute abdominal pain and shock in a puppy. A 7-month-old male intact Shih-Tzu was presented to the emergency service for evaluation of a 12-hour history of vomiting and lethargy progressing to weakness. On presentation, the puppy was obtunded and hypotensive. Radiographs revealed an ill-defined mid-ventral abdominal mass. Ultrasound revealed an echogenic, fluid-filled mass associated with the jejunum. The puppy had an exploratory celiotomy and a 2 × 4 cm oval fluid-filled soft tissue mass was found to be intimately associated, but not communicating with, a section of the mid-jejunum. The mass and associated jejunum were removed via enterectomy. Histopathology of the resected mass revealed heterotopic gastric mucosa; bacterial culture of the fluid contained in the mass revealed heavy growth of Escherichia coli. The puppy recovered from surgery, was discharged from the hospital, and has had no further complications from this episode. Heterotopic gastric mucosa is commonly found incidentally on necropsy. When it has been associated with acute gastrointestinal signs, mechanical intestinal obstruction with or without perforation was noted. To the authors' knowledge, this is the first reported case of heterotopic gastric mucosa leading to abscess formation and acute abdominal pain in the dog. © Veterinary Emergency and Critical Care Society 2014.

    Dopamine is a putative enteric neurotransmitter that has been implicated in exocrine secretory and motility functions of the gastrointestinal tract of several mammalian species including man. This study was designed to determine the presence of dopamine binding sites in human gastric and duodenal mucosa and to describe certain biochemical characteristics of these enteric receptor sites. The binding assay was performed in triplicate with tissue homogenates obtained from healthy volunteers of both sexes using 3 H-dopamine as a ligand. The extent of nonspecific binding was determined in the presence of a 100-fold excess of unlabeled dopamine. Scatchard analysis performed with increasing concentrations of 3 H-dopamine (20-500 nM) revealed a single class of saturable dopamine binding sites in gastric and duodenal mucosa. The results of this report demonstrate the presence of specific dopamine receptors in human gastric and duodenal mucosa. These biochemical data suggest that molecular abnormalities of these receptor sites may be operative in the pathogenesis of important gastrointestinal disorders. 33 references, 2 figures

    Full Text Available BACKGROUND: Anisakiasis is a parasitic disease caused primarily by Anisakis spp. larvae in Asia and in Western countries. The aim of this study was to investigate the genotype of Anisakis larvae endoscopically removed from Middle Eastern Japanese patients and to determine whether mucosal atrophy affects the risk of penetration in gastric anisakiasis. METHODS: In this study, 57 larvae collected from 44 patients with anisakiasis (42 gastric and 2 colonic anisakiasis were analyzed retrospectively. Genotyping was confirmed by restriction fragment length polymorphism (RFLP analysis of ITS regions and by sequencing the mitochondrial small subunit (SSU region. In the cases of gastric anisakiasis, correlation analyses were conducted between the frequency of larval penetration in normal/atrophic area and the manifestation of clinical symptoms. RESULTS: Nearly all larvae were A. simplex seusu stricto (s.s. (99%, and one larva displayed a hybrid genotype. The A. simplex larvae penetrated normal mucosa more frequently than atrophic area (p = 0.005. Finally, patients with normal mucosa infection were more likely to exhibit clinical symptoms than those with atrophic mucosa infection (odds ratio, 6.96; 95% confidence interval, 1.52-31.8. CONCLUSIONS: In Japan, A. simplex s.s. is the main etiological agent of human anisakiasis and tends to penetrate normal gastric mucosa. Careful endoscopic examination of normal gastric mucosa, particularly in the greater curvature of the stomach will improve the detection of Anisakis larvae.

    Epistaxis typically originates from the nasal septum when the nasal mucosa overlying a dilated blood vessel is injured. Epistaxis may, however, signal an underlying condition such as a coagulation disorder, so the treating physician must be alert for signs of serious illness. Most nosebleeds stop spontaneously within 5 minutes with or without pressure to the forehead, nose, or upper lip. Some require anterior nasal packing. A few arise from posterior arteries and require anterior-posterior nasal packing and a referral.

    Human Zonulin, related to the Zonula occludens toxin of Vibrio cholerae, regulates intestinal permeability and is induced in inflammatory disorders of the lower GI tract. Gastroesophageal reflux disease (GERD) is associated with an impairment of epithelial barrier function. Here, we studied expression of zonulin in the gastroesophageal mucosa of 58 patients with typical reflux symptoms and 27 asymptomatic controls. During endoscopy, multiple biopsies from gastroesophageal mucosa were obtained for routine histopathology (Helicobacter pylori-status, inflammation) and gene expression analysis (immunohistochemistry, ELISA). Patients with GERD presented with typical histopathological alterations like elongation of papillae (P=0.015), basal cell hyperplasia (PZonulin was found to be expressed ubiquitously in gastroesophageal mucosa. Mucosal levels in controls ranged between 2.2 and 3.7 ng/microg total protein. Mean values were significantly higher in antrum (3.3+/-1.7 ng/microg) than cardia (2.7+/-1.2n g/microg) and esophagus (2.2+/-1.3 ng/microg) (Pzonulin expression in gastroesophageal mucosa. In conclusion, despite its established role for intestinal permeability, Zonulin seems not to be involved in the regulation of epithelial barrier function in relation to GERD.

By the next day it had spread to the nose and cheek. Patient denies any fever, pain, discharge from the rash, ear or nose, or changes in vision. He denies exposure to any new hygiene products, household cleaning products, recent outdoor activities, travel, or insect bites. Past medical history significant for a childhood varicella infection. Patient works for a moving company, and had an episode of heat exhaustion at work one week prior to onset. Denies alcohol or drug abuse. Significant findings: The unilateral distribution of vesicular lesions over the patient’s left naris, cheek, and upper lip are consistent with Herpes zoster reactivation with Hutchinson’s sign. Hutchinson’s sign is a herpes zoster vesicle present on the tip or side of the nose.1 It reflects zoster involvement of the 1st branch of the trigeminal nerve, and is concerning for herpes zoster ophthalmicus.1 Herpes zoster vesicles may present as papular lesions or macular vesicles on an erythematous base.2,3 Emergent diagnosis must be made to prevent long-term visual sequelae.4 Discussion: The history of a childhood viral exanthem, specifically a past varicella infection, helps direct the diagnosis.2 Herpes zoster ophthalmicus is an ophthalmological emergency and results from viral reactivation within the V1 branch of CN V, leading to direct ocular involvement.1 Symptoms of ocular involvement include red eye, blurry vision, eye pain or photophobia.1 If left untreated, corneal ulceration, scarring, perforation, glaucoma, cataracts, and blindness may occur.1 Fluorescein staining with slit lamp examination will show a characteristic “dendritic ulcer” within the epithelial layer of the cornea.1 Treatment is generally

    Seasonal Allergic rhinitis (SAR) is characterized by runny nose, congestion, sneezing and sinus pressure. A clinical study was performed to demonstrate the efficacy of Lertal®, an innovative food supplement containing Quercetin, Perilla frutescens and Vitamin D3 formu-lated in a double layer "fast-slow" release tablet form, in the relief of symptoms of seasonal allergic rhinitis and in the reduction of consumption of anti-allergic drugs. 23 subjects enrolled in the open clinical study had at least one year history of allergic rhinitis and positive skin prick test or RAST to Parietaria officinalis pollen. At baseline, the subjects had symptoms of nasal and/or ocular seasonal allergic rhinitis. The activity of the food supplement was evaluated using the Total Symptoms Score at first (baseline) and second (final) visit, after one month of supplementation. The consumption of anti-allergic drugs was also evaluated. All subjects enrolled completed the study. The comparison of the scores obtained in the two visits (baseline and final) showed a highly significant reduction of the overall symptoms: approximately 70% for symptom scores and 73% in use of anti-allergic drugs. Sneezing, rhinorrhea, nasal obstruction, ocular itching, lacrimation and congestion of the conjunctiva, all showed a highly significant reduction. No noteworthy side effect was recorded and all patients finished the study with good compliance. The results showed a clear efficacy of the food supplement Lertal® in reducing nasal and/or eye symptoms. This activity was objectively confirmed by the reduction in the consumption of anti-allergic drugs used to relieve symptoms. (www.actabiomedica.it).

    Full Text Available Diversos virus pueden infectar la piel y las mucosas de los seres humanos, manifestándose en diferentes patologías, de acuerdo a la edad, género y estado inmunológico. Un grupo importante de éstos tiene capacidad de replicar en células epiteliales, originando cuadros clínicos en los cuales se evidencia la destrucción celular o bien la hiperplasia del tejido infectado. Gran parte de estos virus persisten en células infectadas por años y tienen la capacidad de reactivarse y de manifestar nuevamente enfermedades cutáneas o mucosas. En algunos casos, ésta sólo se expresa de manera subclínica en una excreción del virus por secreciones que son fuente de infección. En los últimos años, los avances en técnicas moleculares han permitido contar con metodologías diagnósticas cada vez más sensibles, específicas y rápidas. Así como también el progreso en el área de vacunas y antivirales nos entrega mayores herramientas profilácticas y terapéuticas.

    It has been suggested that cholesterol absorption in humans is dependent on bile acid pool composition and that expansion of the cholic acid pool size is followed by an increase of the absorption values. Similar observations were reported in rats. In the present study, therefore, the authors investigated some general properties of human intestinal cholesterol esterase, with particular emphasis on the effect of bile acids on this enzymatic activity. Twenty-nine segments of small intestine were taken during operations; the enzymatic activity was studied by using mucosal homogenate as a source of enzyme and oleic acid, cholesterol, and 14 C-labeled cholesterol as substrates. The time-activity relationship was linear within the first two hours; optimal pH for esterification ranged between 5 and 6.2. There was little difference between the esterifying activity of the jejunal and ileal mucosa. Esterification of cholesterol was observed with all the investigated fatty acids but was maximal with oleic acid. Bile acids did not affect cholesterol esterase activity when present in the incubation mixture at 0.1 and 1.0 mM; the enzymatic activity, however, was significantly inhibited when bile acids were added at 20 mM. In conclusion, this study has shown that the human intestinal mucosa possesses a cholesterol esterase activity; at variance with the rat, however, the human enzyme does not seem to be stimulated by trihydroxy bile acids

    Pemphigus, defines a group of disorders in autoimmune etiology which could be life-threatening and clinical manifestations are mainly epithelial blistering affecting cutaneous and/or mucosal surfaces including oral mucosa. The aim of our study is to evaluate the clinical appearance of pemphigus with oral involvement by reported 15 pemphigus cases. This retrospective study of 15 cases of pemphigus obtained over a period of 7 years from 2006 to 2013 in Istanbul University, Dentistry Faculty, Oral Medicine and Surgery Department was designed. Age distribution of pemphigus was from 15 to 59 years with an average age of 41.3 years. Of the 15 patients, the male:female ratio was 1:2.75 (4 male, 11 female). The most common clinical various of pemphigus was pemphigus vulgaris, diagnosed in all patients. The buccal mucosa (34.3%) was the most commonly affected site followed by tongue (20%), gingiva (17.1%), palate (11.4%), lips (11.4%) and floor of mouth (5.7%). Our explanation of this conclusion, while speculative, is that socioeconomic situation related stress in males and hormonal changes like pregnancy and menostasis in females; systemic disease and using drugs; dental trauma and bruxism could be responsible for flare up in the disease.

    Full text: Radiation accidents involving orphan radioactive sources have happened as a result of people not recognizing the radiation trefoil symbol or from being illiterate and not understanding a warning statement on the radiation source. The trefoil symbol has no inherent meaning to people that have not been instructed in its use. A new radiation warning sign, to supplement the existing trefoil symbol, has been developed to address these issues. Human Factors experts, United Nations member states, and members of the international community of radiation protection professionals were consulted for input on the design of a new radiation warning sign that would clearly convey the message of 'Danger- Run Away- Stay Away' when in close proximity to a dangerous source of radiation. Cultural differences of perception on various warning symbols were taken into consideration and arrays of possible signs were developed. The signs were initially tested in international children for identification with the desired message and response. Based on these test results and further input from radiation protection professionals, five warning signs were identified as the most successful in conveying the desired message and response. These five signs were tested internationally in eleven countries by a professional survey company to determine the best sign for this purpose. The conclusion of the international testing is presented. The new radiation warning sign is currently a draft ISO standard under committee review. The design of the propose d radiation warning sign and the proposed implementation strategy outlined in the draft ISO standard is presented. (authors)

    Full Text Available BACKGROUND: Helicobacter pylori has been isolated from 10%-20% of human chronic cholecystitis specimens but the characteristics of "Helicobacter pylori positive cholecystitis" remains unclear. This study aims to compare the clinicopathological features between chronic cholecystitis patients with and without Helicobacter pylori infection in gallbladder mucosa. METHODS: Three hundred and twenty-six chronic cholecystitis patients were divided into two groups according to whether Helicobacter pylori could be detected by culture, staining or PCR for Helicobacter 16s rRNA gene in gallbladder mucosa. Positive samples were sequenced for Helicobacter pylori-specific identification. Clinical parameters as well as pathological characteristics including some premalignant lesions and the expression levels of iNOS and ROS in gallbladder were compared between the two groups. RESULTS: Helicobacter pylori infection in gallbladder mucosa was detected in 20.55% of cholecystitis patients. These patients had a higher prevalence of acid regurgitation symptoms (p = 0.001, more histories of chronic gastritis (p = 0.005, gastric ulcer (p = 0.042, duodenal ulcer (p = 0.026 and higher presence of Helicobacter pylori in the stomach as compared to patients without Helicobacter pylori infection in the gallbladder mucosa. Helicobacter pylori 16s rRNA in gallbladder and gastric-duodenal mucosa from the same individual patient had identical sequences. Also, higher incidences of adenomyomatosis (p = 0.012, metaplasia (p = 0.022 and higher enhanced expressions of iNOS and ROS were detected in Helicobacter pylori infected gallbladder mucosa (p<0.05. CONCLUSIONS: Helicobacter pylori infection in gallbladder mucosa is strongly associated with Helicobacter pylori existed in stomach. Helicobacter pylori is also correlated with gallbladder premalignant lesions including metaplasia and adenomyomatosis. The potential mechanism might be related with higher ROS

    Esophagus adenocarcinomas developing within heterotopic gastric mucosa are very rare and described to be found endoscopically in a prevalence of .29%. We report a case of cervical adenocarcinoma arising in ectopic gastric mucosa in a fifty-four year old man. The patient underwent a mucosal resection followed with exclusive chemoradiotherapy because of infiltration of the sub mucosa layer. A radiotherapy dose of 60 Gy ( 2 Gy/Fr, 30 Fr) was realized with a reduction of the fields at 50 Gy associated with a continuous 5FU-cisplatin combination after eliminating known mutation in the dihydro-pyrimidine of the dehydrogenase gene. for this tumor, surgery is the main treatment, (oesophagectomy associated with laryngo-pharyngectomy) and has an important repercussion on the quality of life. Because of the refusal of our patient, after a mucosal resection attempt, we proposed our patient a chemoradiotherapy. For the first time in the literature, we report the results of radio chemotherapy for this rare tumor. Eighteen months after the treatment, the patient is alive without sign of recurrence. The radio chemotherapy could be a safety treatment for this rare tumor associated with a good quality of life. A review of the literature since 1950 will be shown. (authors)

    Oral delivery remains a challenge for poorly permeable hydrophilic macromolecules. Poly(amido amine) (PAMAM) dendrimers have shown potential for their possible oral delivery. Transepithelial transport of carboxyl-terminated G3.5 and amine-terminated G4 PAMAM dendrimers was assessed using isolated rat jejunal mucosae mounted in Ussing chambers. The 1 mM FITC-labeled dendrimers were added to the apical side of mucosae. Apparent permeability coefficients (Papp) from the apical to the basolateral side were significantly increased for FITC when conjugated to G3.5 PAMAM dendrimer compared to FITC alone. Minimal signs of toxicity were observed when mucosae were exposed to both dendrimers with respect to transepithelial electrical resistance changes, carbachol-induced short circuit current stimulation, and histological changes. [(14)C]-mannitol fluxes were not altered in the presence of 1 mM dendrimers, suggesting that the paracellular pathway was not affected at this concentration in this model. These results give insight into the mechanism of PAMAM dendrimer transepithelial rat jejunal transport, as well as toxicological considerations important for oral drug delivery.

    Casey, R G

    2012-02-01

    PURPOSE: Testicular symptoms\\/lumps are a cause of concern, anxiety and possible diagnostic dilemma for patient and general practitioner. The majority of scrotal pathology is benign in nature and results in a huge workload. The main aim of this study was to determine the relationship between scrotal symptoms, previous scrotal surgery, testicular self-examination and awareness of scrotal abnormalities. Secondarily, we sought to determine the scrotal findings in men enrolled in a consultant urologist-directed screening programme. METHODS: There were 677 men surveyed on their performance of TSE. They were also asked about scrotal symptoms and prior surgery, before undergoing blinded physical examination by one of four consultant urologists. RESULTS: Among the participants, 9.8% of men had scrotal symptoms with 55% of these having a normal scrotal examination and the rest having benign pathology. A number of men who had undergone previous scrotal surgery (13%) had no clinical findings detected on scrotal examination. No subject was found to have testis cancer; 20.9% had a benign scrotal or inguinal condition detected with the majority (65%) not aware of the abnormality. Men who demonstrate a superior awareness of their scrotal abnormalities were more likely to perform TSE. CONCLUSIONS: Increased awareness of scrotal abnormalities combined with TSE may have a role in improving detection of significant testicular pathology. However, the high prevalence of benign scrotal conditions, of which most men were unaware, may serve to raise anxiety in the patient and general practitioner. We believe there is no role for a one-stop scrotal anxiety clinic, as the costs do not justify the benefits.

    , Candida tropicalis, e Candida guillermondii, o que pode ser explicado pelo uso inadequado de medicamentos e tratamento empírico.PURPOSE: to characterize, phenotypically, yeasts isolated from the vaginal content of 223 symptomatic (S and asymptomatic (A adult women with vulvovaginitis, and to determine the clinical indicators which may lead to the appearance of signs and symptoms related to the mucosa involvement by this pathology. METHODS: a questionnaire with open and closed questions on epidemiological clinical data was applied initially. Then, mycological diagnosis with sowing in Chrom Agar Candida was done, followed by micro-morphological and biochemical identification. Specific methods for the detection of the virulence factors, proteinase and phospholipase were employed. Statistical analysis was performed through χ2 and Pearson's χ2 tests. RESULTS: the most prevalent species found was Candida albicans (87%, S and 67%, A followed by Candida glabrata (4%, S e 17% A. The number of women reporting the use of contraceptives was higher among the symptomatic, 77%. In the two groups studied, about 87% of the women presented regular menstrual cycles and 57% were married with ages between 30 to 40 years old. Concerning the sexual practices, there has been concomitance among anal, oral and vaginal habits from the patients. Only Candida albicans produced the virulence factor phospholipase in 37.5% of them. Proteinase has been detected in Candida albicans, Candida glabrata and Candida parapsilosis. This latter virulence factor was mainly associated to isolates from symptomatic patients. CONCLUSIONS: it is a fact that the vaginal mucosa can be colonized and infected by yeasts, with several Candida species present. Nevertheless, Candida albicans is the most prevalent in the vaginal mucosa of adult women. It is evident the emergence of non-albicans Candida species, some of them with intrinsic resistance to azolics, such as Candida glabrata, Candida parapsilosis, Candida

  15. Signs of political economy

    Bernard Lamizet

    2015-12-01

    Full Text Available Like any political system, economy is a system of signs and representations. The Semiotics of economy elaborates its analytical methods to interpret such signs, which give meaning to the economy by representing its performances in public debate and in the media. Four major features distinguish the Semiotics of political economy from other semiotic forms or other systems of information and political representation. First of all, the relationship between the signification of the economy and the real or the imaginary phenomena to which they refer always pertains to the order of values. The second characteristic of economic signs is the significance of the state of lack they express. The third characteristic of signs of the economy is the form of sign production, which can be designated by the concept of emission of signs and their diffusion. Finally, as all signs, the economic sign is arbitrary. In the field of Economics, such arbitrariness does not imply that the Subject is free to superimpose whatever value to the signs themselves, but refers to the rupture between the world and its possible transformation. The very meaning of the word economy is here at stake. Oikos, in Greek (the term from which the word economy is derived refers to a known, familiar space. Economy transforms the real, natural world into a symbolic social world, into a world of relations with others whom we recognise and whose actions are relatively predictable. It might be useful to consider the contemporary issue of debt, its implications and its multiple meanings, which includes both the ethical and moral dimension of the condemnation of debt as well as the imaginary political dimension based on the expression of an idea of independence.

    Surgical management of proximal and mid ureteral strictures that are not amenable to primary excision and anastomosis is challenging. Although a buccal mucosa graft is commonly used during substitution urethroplasty, its use in substitution ureteroplasty is limited. We describe our technique of robotic ureteroplasty with a buccal mucosa graft to manage complex ureteral strictures and we report our outcomes. We retrospectively reviewed the records of 12 patients who underwent robotic ureteroplasty with a buccal mucosa graft between September 2014 and June 2016. The indication for the procedure was a proximal or mid ureteral stricture not amenable to primary excision and anastomosis. The primary outcomes were clinical success, absent symptoms on ureteral pathology and radiological success, defined as absent ureteral obstruction on retrograde pyelography, renal scan and/or computerized tomography. Four of the 12 patients (33.3%) had a ureteropelvic junction stricture, 4 (33.3%) had a proximal stricture and 4 (33.3%) had a mid ureteral stricture. Eight of the 12 patients (66.7%) had previously undergone failed ureteral reconstruction. Median stricture length was 3 cm (range 2 to 5). Median operative time was 217 minutes (range 136 to 344) and mean estimated blood loss was 100 ml (range 50 to 200). Median length of stay was 1 day (range 1 to 6). At a median followup of 13 months (range 4 to 30) 10 of the 12 cases (83.3%) were clinically and radiologically successful. Robotic ureteroplasty with a buccal mucosa graft is associated with low inherent morbidity. It is an effective way to manage complex proximal and mid ureteral strictures.

    Multibacillary leprosy may involve the oral mucosa, with or without apparent lesions. There are few studies that deal with this issue in the era of multidrug therapy. To assess the frequency of oral mucosa involvement in multibacillary leprosy patients. A transversal study with twenty non-treated multibacillary leprosy patients. The patients were treated in Dracena, São Paulo, between 2000 and 2002. Clinical examination of the oral mucosa was carried out. All patients were submitted to jugal mucosa, soft palate and tongue biopsies, in altered or in pre-established sites. The cross-sections were stained by techniques of hematoxilin-eosin and Ziehl-Neelsen. Granuloma and alcohol-acid-resistant bacilli findings determined the specific histopathological involvement. The study involved 19 patients with an average of 2.5 years of disease progression. Specific histopathological involvement occurred in the tongue and soft palate of one lepromatous patient with an apparently normal oral mucosa. (1) Clinical alterations in the oral mucosa does not imply disease involvement, it is necessary to have histopathological confirmation. (2) Apparent specific clinical alterations are rare. (3) The clinically normal oral mucosa can show specific histopathological involvement.

    AIM: To investigate the reasons for the occurrence of the pink-color sign of iodine-unstained lesions. METHODS: In chromoendoscopy, the pink-color sign of iodine-unstained lesions is recognized as useful for the diagnosis of esophageal squamous cell carcinoma. Patients with superficial esophageal neoplasms treated by endoscopic resection were included in the study. Areas of mucosa with and without the pink-color sign were evaluated histologically. The following histologic features that were possibly associated with the pink-color sign were evaluated. The keratinous layer and basal cell layer were classified as present or absent. Cellular atypia was classified as high grade, moderate grade or low grade, based on nuclear irregularity, mitotic figures, loss of polarity, chromatin pattern and nuclear/cytoplasmic ratio. Vascular change was assessed based on dilatation, tortuosity, caliber change and variability in shape. Vessels with these four findings were classified as positive for vascular change. Endoscopic images of the lesions were captured immediately after iodine staining, 2-3 min after iodine staining and after complete fading of iodine staining. Quantitative analysis of color changes after iodine staining was also performed. RESULTS: A total of 61 superficial esophageal neoplasms in 54 patients were included in the study. The lesions were located in the cervical esophagus in one case, the upper thoracic esophagus in 10 cases, the mid-thoracic esophagus in 33 cases, and the lower thoracic esophagus in 17 cases. The median diameter of the lesions was 20 mm (range: 2-74 mm). Of the 61 lesions, 28 were classified as pink-color sign positive and 33 as pink-color sign negative. The histologic diagnosis was high-grade intraepithelial neoplasia (HGIN) or cancer invading into the lamina propria in 26 of the 28 pink-color sign positive lesions. There was a significant association between pink-color sign positive epithelium and HGIN or invasive cancer (P = 0

    We present a finite model of Peirce`s ten classes of signs. We briefly describe Peirce`s taxonomy of signs; we prove that any finite collection of signs can be extended to a finite algebra of signs in which all interpretants are themselves being interpreted; and we argue that Peirce`s ten classes of signs can be defined using constraints on algebras of signs. The paper opens the possibility of defining multimodal cognitive agents using Peirce`s classes of signs, and is a first step towards building a computational logic of signs based on Peirce`s taxonomies.

    We have repaired 3 cases of the highly contracted socket after irradiation by lining it using antral mucosa and obtained excellent results. Although this procedure requires rhinological skill to obtain the mucosa, it has an advantage leaving no visible scar at the donor site. Usually it is not difficult to obtain a sufficient quantity of the mucous membrane to line a whole socket from one antrum. Besides, it is also easy to line its surface since the shape of antral mucosa is originally in a sac form. All we have to do is making 20 mm long incision to the mucosa, putting a silicone conformer into it, and inlaying it into the graft bed. Thus, having once obtained the mucous membrane, the surgical procedure itself is a quite simple one. (author)

    Full Text Available Background/Aim: The aim of this study was to examine prevalence of different Candida spp. at diabetics and nondiabetics wearing dentures without clinical signs of Denture Stomatitis (DS and to study if some local and systematic factors are confounders for harboring Candida at these subjects. Material and Methods: Total of 60 subjects wearing partial or complete upper acrylic denture having at least half of palatal mucosa covered by denture were selected and stratified into three experimental groups: systematically health subjects; patients with diagnosed Type 2 Diabetes (T2D and good glycoregulation; and T2D subjects with poorly regulated blood sugar level. Cotton swab samples were obtained from each patient from hard palate mucosa and denture surface. Swab cultures were made on Sabouraud dextrose agar and ChromAgar Media for distinciton of various Candida spp. Density growth was also measured. Results: Frequency of Candida spp. findings were similar between groups. At healthy subjects, only C.albicans was detected. At diabetics, C.albicans was the most common isolated species, followed by C.glabrata and C.tropicalis. Negative finding of yeasts on palatal mucosa, but positive on denture surface were detected at all groups, with the highest frequency (33.4% at diabetics with poor glycoregulation. Denture surface was heavier colonized than hard palate mucosa. Duration of diabetes in years were only independent predictors for harboring Candida spp. at denture surface (Exp B=1.186, CI=1.047-1.344, p=0.007. Conclusions: Prosthesis of denture wearers without DS may serve as reservoir of Candida spp. Presence of more pathogenic and resistant non-albicans species are related to diabetics, even without clinical signs of DS.

    Full Text Available The paper discusses ongoing research on the effects of a signing avatar's modeling/rendering features on the perception of sign language animation. It reports a recent study that aimed to determine whether a character's visual style has an effect on how signing animated characters are perceived by viewers. The stimuli of the study were two polygonal characters presenting two different visual styles: stylized and realistic. Each character signed four sentences. Forty-seven participants with experience in American Sign Language (ASL viewed the animated signing clips in random order via web survey. They (1 identified the signed sentences (if recognizable, (2 rated their legibility, and (3 rated the appeal of the signing avatar. Findings show that while character's visual style does not have an effect on subjects' perceived legibility of the signs and sign recognition, it has an effect on subjects' interest in the character. The stylized signing avatar was perceived as more appealing than the realistic one.

    2018-01-01

    Full Text Available BACKGROUND: Postmenopausal women experience undesired symptoms that adversely affect their quality of life. In the recent years, a specific 12 - week fractional CO2 laser treatment has been introduced, with highly significant relief of symptoms. AIM: The aim of this paper is the identification of the early modifications of structural components of atrophic vaginal mucosa induced by laser irradiation, which is responsible for the restorative processes. MATERIAL AND METHODS: We investigated by microscopical, ultrastructural and biochemical methods the modifications of the structural components of postmenopausal atrophic vaginal mucosa tissues after 1 hour following a single fractional laser CO2 application. RESULTS: In one hour, the mucosal epithelium thickens, with the maturation of epithelial cells and desquamation at the epithelial surface. In the connective tissue, new papillae indenting the epithelium with newly formed vessels penetrating them, new thin fibrils of collagen III are also formed in a renewed turnover of components due to the increase of metalloproteinase - 2. Specific features of fibroblasts support stimulation of their activity responsible of the renewal of the extracellular matrix, with an increase of mechanical support as connective tissue and stimulation of growth and maturation to epithelium thanks to new vessels and related factors delivered. CONCLUSION: We found the activation of regenerative mechanisms expressed both in the connective tissue - with the formation of new vessels, new papillae, and new collagen - and in the epithelium with the associated thickening and desquamation of cells at the mucosal surface.

    Objective: To study histopathological changes in nasal mucosa of guinea pigs following a series of irradiation. Methods: A total of 60 healthy guinea pigs were divided into two groups randomly: the irradiation group (n=30) and the control group (n=30). The animals of the irradiation group were exposed nasally to linear accelerator X-rays at 5.0 Gy once a week for three weeks. At 1 d, 1 w, 2 w, 4 w, 10 w and half year after X-irradiation five animals per one group were sacrificed randomly, at each time point. Their middle nasal turbinate mucosa was observed under optical microscope and electron microscope, and were analysed by image analysis for histopathological transformation. Results: In the irradiation group, the early histopathological transformation was acute inflammatory reaction, at the fourth week the mucosa began to repair, which ended at the sixth month. But after repaired, some parts of the repaired mucosa were lined with squamous epithelium instead of the normal nasal mucosa. The rate of the cilia-covered area was only 52.9% at the sixth month. Conclusion: The nasal mucosa injury and the squamous metaplasia could form a pathological basis of dysfunction after irradiation

    Full Text Available Background Hypochlorite solution is widely used in dental practice during root canal treatment. Although it is generally regarded as being very safe, potentially severe complications can occur when it comes into contact with soft tissue especially due to its cytotoxic features. Objective The aim of our paper is to present a case of damage of oral mucosa because of leakage of 3% hypochlorite through rubber dam during endodontic treatment. Material and methods We present a 31 years old female with necrosis of buccal mucosa during the endodontic treatment of 46. Results Three days after the procedure the patient was referred to our department for consultation and treatment. Antiseptic lavage was performed and oral antibiotic was administrated. After 5 days intraoral examination showed signs of almost full recovery. Conclusion The need for proper tooth isolation during restorative procedures is obvious. Anything that obscures the operative field negatively impacts operator efficiency and effectiveness. Visibility, patient/operator safety, infection control and the physical properties of dental materials are all compromised when proper isolation is lacking.

    Leptin, a 16 kDa circulating anti-obesity hormone, exhibits many physiological properties. Recently, leptin was isolated from saliva; however, its function in the oral cavity is still unclear. In this study, we investigated the physiological role of leptin in the oral cavity by focusing on its effect on wound healing in the oral mucosa. Immunohistochemical analysis was used to examine the expression of the leptin receptor (Ob-R) in human/rabbit oral mucosa. To investigate the effect of leptin on wound healing in the oral mucosa, chemical wounds were created in rabbit oral mucosa, and leptin was topically administered to the wound. The process of wound repair was histologically observed and quantitatively analyzed by measuring the area of ulceration and the duration required for complete healing. The effect of leptin on the proliferation, differentiation and migration of human oral mucosal epithelial cells (RT7 cells) was investigated using crystal violet staining, reverse transcription polymerase chain reaction (RT-PCR) and a wound healing assay, respectively. Ob-R was expressed in spinous/granular cells in the epithelial tissue and vascular endothelial cells in the subepithelial connective tissue of the oral mucosa. Topical administration of leptin significantly promoted wound healing and shortened the duration required for complete healing. Histological analysis of gingival tissue beneath the ulceration showed a denser distribution of blood vessels in the leptin-treated group. Although the proliferation and differentiation of RT7 cells were not affected by leptin, the migration of these cells was accelerated in the presence of leptin. Topically administered leptin was shown to promote wound healing in the oral mucosa by accelerating epithelial cell migration and enhancing angiogenesis around the wounded area. These results strongly suggest that topical administration of leptin may be useful as a treatment to promote wound healing in the oral mucosa.

    Full Text Available Background: The oral mucosa lining the oral cavity is composed of epithelium supported by connective tissue. The shape of the epithelial-connective tissue interface has traditionally been used to describe physiological and pathological changes in the oral mucosa. Aim: The aim is to evaluate the morphometric complexity in normal, dysplastic, well-differentiated, and moderately differentiated squamous cell carcinoma (SCC of the oral mucosa using fractal geometry. Materials and Methods: A total of 80 periodic acid–Schiff stained histological images of four groups: normal mucosa, dysplasia, well-differentiated SCC, and moderately differentiated SCC were verified by the gold standard. These images were then subjected to fractal analysis. Statistical Analysis: ANOVA and post hoc test: Bonferroni was applied. Results: Fractal dimension (FD increases as the complexity increases from normal to dysplasia and then to SCC. Normal buccal mucosa was found to be significantly different from dysplasia and the two grades of SCC (P < 0.05. ANOVA of fractal scores of four morphometrically different groups of buccal mucosa was significantly different with F (3,76 = 23.720 and P< 0.01. However, FD of dysplasia was not significantly different from well-differentiated and moderately differentiated SCC (P = 1.000 and P = 0.382, respectively. Conclusion: This study establishes FD as a newer tool in differentiating normal tissue from dysplastic and neoplastic tissue. Fractal geometry is useful in the study of both physiological and pathological changes in the oral mucosa. A new grading system based on FD may emerge as an adjuvant aid in cancer diagnosis.

    Full Text Available La Úlcera Eosinófila de la Mucosa Oral, es una entidad poco frecuente, pobremente descrita en la literatura mundial. Se define como una lesión benigna autolimitada que si bien puede presentarse en distintas áreas de la cavidad bucal, presenta una marcada predilección por la mucosa ventral de la lengua. Clínicamente, se presenta como una lesión ulcerada de bordes indurados y sobreelevados. Los hallazgos histopatológicos son característicos y consisten en un infiltrado mixto rico en eosinófilos, acompañado de una población de grandes células mononucleadas. Recientes artículos basados en estudios inmunohistoquimicos, permiten afirmar la presencia de grandes linfocitos atípicos CD30+ y por lo tanto, incluir esta lesión en el espectro de las entidades simuladoras de desordenes linfoproliferativos. A pesar de esto, el mecanismo etiopatogenico permanece oscuro y el trauma local juega un rol todavía no dilucidado; aunque se halla presente en la mayoría de las publicaciones, explicando el fenómeno como un mecanismo reactivo. La importancia de esta lesión, radica en su diagnostico diferencial por su semejanza clínica al carcinoma espinocelular, histoplasmosis, chancro sifilítico, Úlcera tuberculosa, carcinoma epidermoide y otras. En nuestro trabajo se revisa la literatura y se discuten la características clínicas, histopatológicas y alternativas terapéuticas, a partir del artículo de un caso clínico en una paciente joven, que luego de la biopsia escisión como método para el diagnostico de certeza, se produce una recidiva de la lesión; lo que orientó el tratamiento hacia la cirugía combinada con corticoterapia local intralesional, logrando su remisión.Eosinophilic Ulcer of the Oral Mucosa, an entity, poorly deciphers in world-wide literature.

    The climate is beginning to behave in unusual ways. The global temperature reached unprecedented highs in 2015 and 2016, which led climatologists to predict an enormous El Nino that would cure California's record drought. It did not happen the way they expected. That tells us just how unreliable temperature has become as an indicator of important aspects of climate change. The world needs to go beyond global temperature to a set of planetary vital signs. Politicians should not over focus policy on one indicator. They need to look at the balance of evidence. A coalition of scientists and policy makers should start to develop vital signs at once, since they should be ready at the entry into force of the Paris Agreement in 2020. But vital signs are only the beginning. The world needs to learn how to use the vast knowledge we will be acquiring about climate change and its impacts. Is it not time to use all the tools at hand- observations from space and ground networks; demographic, economic and societal measures; big data statistical techniques; and numerical models-to inform politicians, managers, and the public of the evolving risks of climate change at global, regional, and local scales? Should we not think in advance of an always-on social and information network that provides decision-ready knowledge to those who hold the responsibility to act, wherever they are, at times of their choosing?

    To study the effect of hypertonic seawater and isotonic seawater for nasal mucosa of allergic rhinitis mice model, and explore the possible mechanism of nasal irrigation with seawater in treatment of allergic rhinitis. We used Der pl to make allergic rhinitis model of BALB/c mice, and divided them into three groups randomly. Nasal irrigation with hypertonic seawater (HS) or isotonic seawater (IS) in the treatment group 1-14 days after modeling, and black control (BC) group was given no treatment after modeling. Normal control (NC) group was given no treatment, the number of rubs and sneezings in each group were counted in 30 min after the last nasal irrigation. Mice were then killed 24 h after the last therapy. The noses of mice from each group were removed and fixed, then the slices were stained with hematoxylin and eosin, the others were observed by transmission electron microscope. Mice with hypertonic seawater and isotonic seawater were significantly improved in rubs and sneezings compared to the black control group (P 0. 05); Ciliated columnar epithelium cells in mucosal tissues of HS group and IS group were arranged trimly, better than that in the black control group. Morphology and microstructure in nasal mucosal of HS group was closer to the normal group than in IS group. The injury of nasal mucosa ciliated epithelium was significantly improved by nasal irrigation with hypertonic seawater and isotonic seawater, and the former is better than the latter, the mechanism of nasal irrigation with seawater in treatment of allergic rhinitis may rely on repairing the injured nasal mucosa ciliated epithelium, thereby the symptoms of nasal was reduced.

  19. Sign Lowering and Phonetic Reduction in American Sign Language.

    Science.gov (United States)

    Tyrone, Martha E; Mauk, Claude E

    2010-04-01

    This study examines sign lowering as a form of phonetic reduction in American Sign Language. Phonetic reduction occurs in the course of normal language production, when instead of producing a carefully articulated form of a word, the language user produces a less clearly articulated form. When signs are produced in context by native signers, they often differ from the citation forms of signs. In some cases, phonetic reduction is manifested as a sign being produced at a lower location than in the citation form. Sign lowering has been documented previously, but this is the first study to examine it in phonetic detail. The data presented here are tokens of the sign WONDER, as produced by six native signers, in two phonetic contexts and at three signing rates, which were captured by optoelectronic motion capture. The results indicate that sign lowering occurred for all signers, according to the factors we manipulated. Sign production was affected by several phonetic factors that also influence speech production, namely, production rate, phonetic context, and position within an utterance. In addition, we have discovered interesting variations in sign production, which could underlie distinctions in signing style, analogous to accent or voice quality in speech.

    Arthroscopic examination of the tendon has been described as the "gold standard" for diagnosis of tendinitis of the long head of the biceps (LHB). An arthroscopic finding of an inflamed and hyperemic LHB within the bicipital groove has been described as the "lipstick sign." Studies evaluating direct visualization in diagnosis of LHB tendinitis are lacking. During a 1-year period, 363 arthroscopic shoulder procedures were performed, with 16 and 39 patients prospectively selected as positive cases and negative controls, respectively. All positive controls had groove tenderness, positive Speed maneuver, and diagnostic ultrasound-guided bicipital injection. Negative controls had none of these findings. Six surgeons reviewed randomized deidentified arthroscopic pictures of enrolled patients The surgeons were asked whether the images demonstrated LHB tendinitis and if the lipstick sign was present. Overall sensitivity and specificity were 49% and 66%, respectively, for detecting LHB tendinitis and 64% and 31%, respectively, for erythema. The nonweighted κ score for interobserver reliability ranged from 0.042 to 0.419 (mean, 0.215 ± 0.116) for tendinitis and from 0.486 to 0.835 (mean, 0.680 ± 0.102) for erythema. The nonweighted κ score for intraobserver reliability ranged from 0.264 to 0.854 (mean, 0.615) for tendinitis and from 0.641 to 0.951 (mean, 0.783) for erythema. The presence of the lipstick sign performed only moderately well in a rigorously designed level III study to evaluate its sensitivity and specificity. There is only fair agreement among participating surgeons in diagnosing LHB tendinitis arthroscopically. Consequently, LHB tendinitis requiring tenodesis remains a clinical diagnosis that should be made before arthroscopic examination. Published by Elsevier Inc.

    Lichen planus (LP) is a chronic inflammatory disease of unknown aetiology affecting the skin and oral mucosa. Oral lichenoid lesions (OLLs), like oral contact reactions, may resemble oral lichen planus (OLP) both clinically and histopathologically. As OLP and OLL are hyperkeratotic diseases and filaggrin is essential to keratinization, the distribution of filaggrin may be altered in these lesions. To investigate whether patients with OLP/OLL have (i) altered distribution of filaggrin in the oral mucosa; (ii) a higher incidence of mutations in the filaggrin gene (FLG); (iii) active dermatoses, apart from cutaneous LP, than healthy controls; and (iv) patients with OLP/OLL and a defect in the FLG have more widespread oral lesions and report more symptoms than OLP/OLL patients without a concomitant defect in the FLG. Forty-nine Caucasian patients (42 women and 7 men, mean age 61.0 ± 10.3 years), with symptomatic OLP, OLL or stomatitis, and 29 matched healthy controls underwent a clinical oral and dermatological examination, oral mucosal biopsy and filaggrin genotyping (testing for R2447X, R501X, 2282del4). Smear tests for Candida spp. were performed in all patients to exclude oral candidiasis. Immunohistochemistry were performed using poly- and monoclonal filaggrin antibodies. The immunoreactivity for filaggrin was significantly more intense in the oral mucosa in the patients with OLP/OLL compared with healthy controls (P = 0.000025). No difference was noted in the incidence of defects in the FLG and active dermatoses between patients and healthy controls. No difference was noted in extension and number of symptoms reported by patients with OLP/OLL with or without a concomitant defect in the FLG. OLP/OLL is associated with an altered distribution of filaggrin in the oral mucosa independently of defects in the FLG. Patients with OLP/OLL did not display more active dermatoses other than cutaneous LP when compared to healthy controls. © 2016 European Academy of

    Entry into hazardous areas without the proper protective equipment is extremely dangerous and must be prevented whenever possible. Current postings of radiological hazards at the Rocky Flats Environmental Technology Site (RFETS) do not incorporate recent findings concerning effective warning presentation. Warning information should be highly visible, quickly, and easily understood. While continuing to comply with industry standards (e.g., Department of Energy (DOE) guidelines), these findings can be incorporated into existing radiological sign design, making them more effective in terms of usability and compliance. Suggestions are provided for designing more effective postings within stated guidelines

    Oral mucosa reaction of prosthetic bed to the removable acrylic dentures was evaluated in 43 patients (12 male and 31 female) aged 56-69 years with partial and full teeth loss in one or both jaws. Patients of the first (control) group (17 patients) were not using additional tools improving fixation of the removable dentures during adaptation period, while patients of the second (main) group (26 patients) used Corega cream for dentures fixation for 30 days follow-up. Oral mucosa assessment was carried out on 3-4 and 28-30 day of dentures use by 3 end points: pain syndrome, moisture level, inflammation of a prosthetic bed. The results proved Corega cream to improve prosthetic bed mucosa condition reducing inflammatory response to polymeric materials of removable dentures basis.

    Full Text Available Buccal carcinoma is one of the most common malignant neoplasms among all oral cancers in India. Understanding the role of speech language pathologists (SLPs in the domains of evaluation and management strategies of this condition is limited, especially in the Indian context. This is a case report of a young adult with recurrent squamous cell carcinoma of the buccal mucosa with no deleterious habits usually associated with buccal mucosa carcinoma. Following composite resection, pectoralis major myocutaneous flap reconstruction, he developed severe oral dysphagia and demonstrated unintelligible speech. This case report focuses on the issues of swallowing and speech deficits in buccal mucosa carcinoma that need to be addressed by SLPs, and the outcomes of speech and swallowing rehabilitation and prognostic issues.

    2014-01-01

    Full Text Available Oral mucosa has been the most popular substitute material for urethral reconstructive surgery because it is easy to harvest, is easy to access, has a concealed donor site scar, and obviates most of the problems associated with other grafts. However, the success of using oral mucosa for urethral surgery is mainly attributed to the biological properties of this tissue. Herein, the surgical steps of harvesting oral mucosa from the inner cheek are presented with an emphasis on tips and tricks to render the process easier and more reproducible and to prevent intra and post-operative complications. The following steps are emphasized: Nasal intubation, ovoid shape graft, delicate harvesting leaving the muscle intact, donor site closure and removal of submucosal tissue.

    Lamina propria (LP) of gastric mucosa plays an important role in progression of gastric cancer because of the site at where inflammatory reactions occur. Multiphoton imaging has been recently employed for microscopic examination of intact tissue. In this paper, using multiphoton microscopy (MPM) based on two-photon excited fluorescence (TPEF) and second harmonic generation (SHG), high resolution multiphoton microscopic images of lamina propria (LP) are obtained in normal human gastric mucosa at excitation wavelength {lambda}{sub ex} = 800 nm. The main source of tissue TPEF originated from the cells of gastric glands, and loose connective tissue, collagen, produced SHG signals. Our results demonstrated that MPM can be effective for characterizing the microstructure of LP in human gastric mucosa. The findings will be helpful for diagnosing and staging early gastric cancer in the clinics.

    We evaluated the efficacy and outcome of one-stage oral mucosa graft urethroplasty, which is currently the procedure of choice for treating lengthy and complicated urethral strictures not amenable to excision and primary end-to-end anastomosis. Seven patients 33 to 74 years old (mean age = 53.7) underwent one-stage oral mucosa graft urethroplasty for a stricture in either the bulbar urethra (four patients), penile urethra (two patients), or pan-anterior urethra (one patient). Three of the strictures were due to trauma, one was due to inflammation, and one was due to a failed hypospadia repair. The other two were iatrogenic. All patients had previously undergone either internal urethrotomy or repeated urethral dilation. Three patients received a tube graft, three received a ventral onlay, and one received a dorsal onlay. A free graft of oral mucosa was harvested from the inside of each patient's left cheek, and if necessary to obtain a sufficient length, the harvest was extended to include mucosa from the lower lip and the right cheek. The graft lengths ranged from 2.5 to 12 cm (mean = 4.6 cm). A urethral catheter was left in place for 3 weeks postoperatively. While no severe complications at the donor site were observed during follow-up periods ranging from 3 to 55 months (mean = 14 months), two patients who had received a tube graft developed distal anastomotic ring strictures that were managed by internal urethrotomy. The other five required no postoperative urological procedure even though one who had received a ventral onlay developed a penoscrotal fistula. Oral mucosa is an ideal urethral graft, and oral mucosa graft urethroplasty is an effective procedure for repairing complicated urethral strictures involving long portions of the urethra.

    Nasal packings are commonly accepted in the treatment of severe epistaxis. Cuffed catheters are known to cause damage to the nasal mucosa most likely by interfering with tissue perfusion. In this study the effect of different pressure levels on local perfusion of septal mucosa is investigated. In 15 healthy subjects the blood flow in septal mucosa was measured by laser doppler flowmetry by positioning a cuffed epistaxis catheter into the nasal cavity with a laser probe attached to it. Increasing pressure was administered by injecting saline solution while continuously recording intraluminal pressure, perfusion, and filling volume. The local pressure affecting the septal mucosa at the moment of stalling perfusion was determined by subtracting the extranasal cuff pressure from the current intranasal cuff pressure at same inflation volumes. Microcirculation of the septal mucosa stopped when the local pressure exceeded a value of Pmean = 42 mmHg. Individual variations (n = 15) were small (s = 9 mmHg). The intraluminal cuff pressure was measured to be about ten times higher due to the retraction force of the cuff. Spontaneous oscillations of the blood flow were reduced with increasing pressure to the blood vessels. Filling volumes up to 3.2 ml were sufficient to stop perfusion. Cuffed nasal packings stop the blood flow in nasal mucosa even at low local pressures. Depending on the material characteristics of different cuffs the pressure to dilate the cuff may, however, be several times higher than the actual local pressure. This effect may cause problems in the proper use of cuffed catheters. Laser doppler flowmetry proved to be helpful in determining reproducible perfusion values.

    Using the method of electrophoresis in agar gel soluble proteins of gastric mucosa of rats were separated into 11 fractions. Proteins posessing a proteolytic (pH 1.8) and lipase (pH 7.4) activity were localized within the second and third prealbumin fractions. Soluble proteins of gastric mucosa contain glyco- and lipoproteid complexes. Exposure of rats to 1000 R of X-rays induces quantitative redistribution within the electrophoretic spectrum of soluble proteins and a considerable disturbance of the proteolytic activity of total soluble proteins throughout the entire period of observation (from 10 min to 72h)

    Full Text Available Bacterial adhesion to the intestinal epithelium is a critical initial step in the pathogenesis of many enteric diseases. Helicobacter pylori is a duodenal pathogen that adheres to the gastric epithelium and causes gastritis and peptic ulceration. The mechanism by which H pylori causes disease has not yet been elucidated but adherence to the gastric mucosa is thought to be an important virulence determinant of the organism. What is known about adherence of H pylori to the gastric mucosa is summarized. Topics discussed are the mechanism of H pylori adherence; in vitro and in vivo models of H pylori infection; and adherence and potential adhesins and receptors for H pylori.

    In general, the psoas sign has been known to be a reliabler index of presence of a retroperitoneal pathology. However, obliterated psoas margin may be caused by various other conditions in so far as the amount of fat around the psoas muscle is not enough to be visualized. On the other hand, retroperitoneal pathology does not always obliterates the psoas margin. Authors analyzed obliterated psoas margins in 72 patients by comparing simple radiographs and computed tomography, and attempted to explain the mechanism of obliterated psoas margin, on simple radiograph. The results are as follows : 1. The psoas margin is obliterated by the retroperitoneal pathology and various other conditions such as kidney-psoas contract, scanty extraperitoneal fat, scoliosis, bowel interposition and angled psoas muscle. 2. The psoas margin is preserved as far as the perinephric fat is intact and X-ray beam strikes the lateral margin of the psoas muscle tangentially. 3. The psoas sign is considered not to be a reliable index of a retroperitoneal pathology

    symptoms in the adult population, the sociodemographic factors associated with them, and the actions taken as a result of these symptoms, according to sex. METHODS: A population-based cross-sectional study was carried out in the city of Rio Grande (state of Rio Grande do Sul, Brazil, in 2000. We interviewed 1 259 people Ž 15 years of age. Data were collected using a structured questionnaire containing 18 symptoms in addition to sociodemographic questions. The prevalence of symptoms and prevalence ratios for sex, age, and socioeconomic status were estimated after alternately adjusting for these variables. The actions resulting from the presence of symptoms were also analyzed for each sex. RESULTS: Mean age was 40.33 years (53.9% were women. The most prevalent symptom was headache (55.4%. Joint pain, insomnia, constipation, high blood pressure, and shortness of breath increased with age. The following were more prevalent among the lower social classes: headache, nervousness, joint and back pain, insomnia and depression, high blood pressure, chest pain, and shortness of breath. A total of 4 424 health problems were reported (an average of 3.25 per person; 60.2% did not generate any action, 31.6% resulted in self-medication, and 8.2% resulted in a visit to a medical facility. Headache, nervousness, joint and back pain, insomnia, depression, constipation, high blood pressure, chest pain, and shortness of breath were significantly higher in women, whereas cough was significantly more prevalent in men. Women and men took similar actions in the presence of signs and symptoms. CONCLUSION: It is necessary to establish health policies that lay an emphasis on mental health and education for self care and on those symptoms that signal the need to go to a health facility. It is also necessary to study the role of social class in determining health behavior and the choice to seek care.

    The early CT finding of an hyperdensity of a portion of the middle cerebral artery Hyperdense Middle Cerebral Artery Sign (HMCAS), in patients with supratentorial stroke, is often indicative of an embolic occlusion. Aim of this study was to verify the incidence and reliability of the HMCAS and its possible correlation with early CT findings and with the extent of late brain damage. We studied 36 patients presenting with symptoms of stroke in the MCA territory, by means of CT and angiography performed respectively within 4 and 6 hours. Follow-up CT scans were then obtained after one week and three months from the ischemic event. The HMCAS was present in 50% of our patients and in this group it always correlated positively with the angiographic finding of occlusion. The same group presented a high incidence of early CT hypodensity (88%). Finally the presence of HMCAS might be considered a negative prognostic sign for the development of extensive brain damage.

  12. Translating Signs, Producing Subjects

    Directory of Open Access Journals (Sweden)

    Brett Neilson

    2009-08-01

    Full Text Available This paper moves between two streets: Liverpool Road in the Sydney suburb of Ashfield and Via Sarpi in the Italian city of Milan. What connects these streets is that both have become important sites for businesses in the Chinese diaspora. Moreover, both are streets on which locals have expressed desires for Chinese signs to be translated into the national lingua franca. The paper argues that the cultural politics inherent in this demand for translation cannot be fully understood in the context of national debates about diversity and integration. It is also necessary to consider the emergence of the official Chinese Putonghua as global language, which competes with English but also colonizes dialects and minority languages. In the case of these dual language signs, the space between languages can neither be reduced to a contact zone of minority and majority cultures nor celebrated as a ‘third space’ where the power relations implied by such differences are subverted. At stake is rather a space characterised by what Naoki Sakai calls the schema of co-figuration, which allows the representation of translation as the passage between two equivalents that resemble each other and thus makes possible their determination as conceptually different and comparable. Drawing on arguments about translation and citizenship, the paper critically interrogates the ethos of interchangeability implied by this regime of translation. A closing argument is made for a vision of the common that implies neither civilisational harmony nor the translation of all values into a general equivalent. Primary sources include government reports, internet texts and media stories. These are analyzed using techniques of discourse analysis and interpreted with the help of secondary literature concerning globalisation, language and migration. The disciplinary matrix cuts and mixes between cultural studies, translation studies, citizenship studies, globalization studies and

    Full Text Available A signed graph (or, $sigraph$ in short is a graph G in which each edge x carries a value $\\sigma(x \\in \\{-, +\\}$ called its sign. Given a sigraph S, the negation $\\eta(S$ of the sigraph S is a sigraph obtained from S by reversing the sign of every edge of S. Two sigraphs $S_{1}$ and $S_{2}$ on the same underlying graph are switching equivalent if it is possible to assign signs `+' (`plus' or `-' (`minus' to vertices of $S_{1}$ such that by reversing the sign of each of its edges that has received opposite signs at its ends, one obtains $S_{2}$. In this paper, we characterize sigraphs which are negation switching invariant and also see for what sigraphs, S and $\\eta (S$ are signed isomorphic.

    Full Text Available Shisha is a water pipe that tobacco extract and fruit scented burnt using coal. It produces the smoke through the vessel and inhaled using a hose with good taste. The culture of shisha smoking is popular in Midle East country that curently has been also entering Indonesia. The side effect of shisha smoking habit is still very rare reported. Aim of this study is to describe the oral mucosa condition of shisha user. A preliminary observasional study was conducted at several sisha cafe at South Jakarta. Under informed consent, subject with habit of tobacco and shisha smoker were included. Sociodemographic data (age, gender, duration, frequency of smoking, salivary flow rate and oral mucosa changes were documented. Eighteen subjects were recruited into this study. Most of shisha smoker was also tobacco smoker. Shisha was more practiced by male at  age (15-24 years old. The oral mucosa changes such as keratosis, melanosis, leukoedema, coated tongue, gingivitis and xerostomia were found on subject with habit of tobacco smoking habit only or both shisha and tobacco smoking. In conclusion apparently the shisha smoking habit may casue oral mucosa changes almost the same with tobacco smoking habit

    Buccal mucosa ridging (BMR) is known as a clinical sign of clenching, which is one of the major manifestations of bruxism. However, there are few reports about the formation of BMR and no data regarding the association between BMR and factors such as malocclusion. The purpose of the current study was to investigate the relationship between BMR and factors such as the number of teeth present, gender, body mass index (BMI), occlusion and clenching habit in university students. A total of 2101 students (1164 males, 937 females), aged 18-29 years old, were included in the study. BMR and the number of teeth present were recorded and malocclusion was defined using a modified version of the Index of Orthodontic Treatment Need. Additional information regarding gender, clenching habit and BMI was collected via a questionnaire. Forty-six per cent of the subjects had BMR and the prevalence of BMR in females was significantly higher than that of males (chi square test, p BMR was significantly associated with female gender (OR = 1.501, 95% CI = 1.259-1.790, p BMR was not associated with awareness of clenching habit and BMI. Gender, crowding and overjet were related to the formation of BMR in university students. When evaluating BMR as a clinical sign of clenching, one might have to take factors such as gender and crowding into consideration.

    During irradiation of volumes that incorporate the olfactory system, a proportion of patients have complained of a pungent smell. A retrospective study was carried out to determine the prevalence of this side-effect. A questionnaire was sent to 40 patients whose treatment volumes included the olfactory region and also to a control group treated away from this region. The irradiated tumor volumes included the frontal lobe, whole brain, nasopharynx, pituitary fossa, and maxillary antrum. Of the 25 patients who replied, 60% experienced odorous symptoms during irradiation. They described the odor as unpleasant and consistent with ozone. Stimulation of olfactory receptors is considered to be caused by the radiochemical formation of ozone and free radicals in the mucus overlying the olfactory mucosa

    2008-01-01

    This study aims to answer the question, how much of Spanish Sign Language interpreting deaf individuals really understand. Study sampling included 36 deaf people (deafness ranging from severe to profound; variety depending on the age at which they learned sign language) and 36 hearing people who had good knowledge of sign language (most were interpreters). Sign language comprehension was assessed using passages of secondary level. After being exposed to the passages, the participants had to tell what they had understood about them, answer a set of related questions, and offer a title for the passage. Sign language comprehension by deaf participants was quite acceptable but not as good as that by hearing signers who, unlike deaf participants, were not only late learners of sign language as a second language but had also learned it through formal training.

    2012-01-01

    This work proposes a design methodology using ergonomics and anthropometry concepts applied to traffic sign and street name sign projects. Initially, a literature revision on cognitive ergonomics and anthropometry is performed. Several authors and their design methodologies are analyzed and the aspects to be considered in projects of traffic and street name signs are selected and other specific aspects are proposed for the design methodology. A case study of the signs of "Street of Antiques" in Porto Alegre city is presented. To do that, interviews with the population are made to evaluate the current situation of signs. After that, a new sign proposal with virtual prototyping is done using the developed methodology. The results obtained with new interviews about the proposal show the user satisfaction and the importance of cognitive ergonomics to development of this type of urban furniture.

    Purpose: Rectal toxicity (proctitis) is a dose-limiting factor in pelvic radiation therapy. Mucosal atrophy, i.e., net extracellular matrix degradation, is a prominent feature of radiation proctitis, but the underlying mechanisms are not known. We prospectively examined changes in matrix metalloproteinase (MMP)-2 and MMP-9 (gelatinase A and B) in the rectal mucosa during radiation therapy of prostate cancer, as well as the relationships of these changes with symptomatic, structural, and cellular evidence of radiation proctitis. Methods and Materials: Seventeen patients scheduled for external beam radiation therapy for prostate cancer were prospectively enrolled. Symptoms of gastrointestinal toxicity were recorded, and endoscopy with biopsy of the rectal mucosa was performed before radiation therapy, as well as 2 and 6 weeks into the treatment course. Radiation proctitis was assessed by endoscopic scoring, quantitative histology, and quantitative immunohistochemistry. MMP-2 and MMP-9 were localized immunohistochemically, and activities were determined by gelatin zymography. Results: Symptoms, endoscopic scores, histologic injury, and mucosal macrophages and neutrophils increased from baseline to 2 weeks. Symptoms increased further from 2 weeks to 6 weeks, whereas endoscopic and cellular evidence of proctitis did not. Compared to pretreatment values, there was increased total gelatinolytic activity of MMP-2 and MMP-9 at 2 weeks (p=0.02 and p=0.004, respectively) and 6 weeks (p=0.006 and p=0.001, respectively). Active MMP-2 was increased at both time points (p=0.0001 and p=0.002). Increased MMP-9 and MMP-2 at 6 weeks was associated with radiation-induced diarrhea (p=0.007 and p=0.02, respectively) and with mucosal neutrophil infiltration (rho=0.62). Conclusions: Pelvic radiation therapy causes increased MMP-2 and MMP-9 activity in the rectal mucosa. These changes correlate with radiation-induced diarrhea and granulocyte infiltration and may contribute to abnormal

    2014-01-01

    We have validated differences in DNA methylation levels of candidate genes previously reported to discriminate between normal colon mucosa of colon cancer patients and normal colon mucosa of individuals without cancer. Here, we report that CpG sites in 16 of the 30 candidate genes selected show significant differences in mean methylation level in normal colon mucosa of 24 cancer patients and 24 controls. A support vector machine trained on these data and data for an additional 66 CpGs yielded an 18-gene signature, composed of 10 of the validated candidate genes plus eight additional candidates. This model exhibited 96% sensitivity and 100% specificity in a 40-sample training set and classified all eight samples in the test set correctly. Moreover, we found a moderate-strong correlation (Pearson coefficients r=0.253-0.722) between methylation levels in colon mucosa and methylation levels in peripheral blood for seven of the 18 genes in the support vector model. These seven genes, alone, classified 44 of the 48 patients in the validation set correctly and five CpGs selected from only two of the seven genes classified 41 of the 48 patients in the discovery set correctly. These results suggest that methylation biomarkers may be developed that will, at minimum, serve as useful objective and quantitative diagnostic complements to colonoscopy as a cancer-screening tool. These data also suggest that it may be possible to monitor biomarker methylation levels in tissues collected much less invasively than by colonoscopy. PMID:24806665

  8. Mitochondrial dysfunction in the gastrointestinal mucosa of children with autism: A blinded case-control study.

    Directory of Open Access Journals (Sweden)

    Shannon Rose

    Full Text Available Gastrointestinal (GI symptoms are prevalent in autism spectrum disorder (ASD but the pathophysiology is poorly understood. Imbalances in the enteric microbiome have been associated with ASD and can cause GI dysfunction potentially through disruption of mitochondrial function as microbiome metabolites modulate mitochondrial function and mitochondrial dysfunction is highly associated with GI symptoms. In this study, we compared mitochondrial function in rectal and cecum biopsies under the assumption that certain microbiome metabolites, such as butyrate and propionic acid, are more abundant in the cecum as compared to the rectum. Rectal and cecum mucosal biopsies were collected during elective diagnostic colonoscopy. Using a single-blind case-control design, complex I and IV and citrate synthase activities and complex I-V protein quantity from 10 children with ASD, 10 children with Crohn's disease and 10 neurotypical children with nonspecific GI complaints were measured. The protein for all complexes, except complex II, in the cecum as compared to the rectum was significantly higher in ASD samples as compared to other groups. For both rectal and cecum biopsies, ASD samples demonstrated higher complex I activity, but not complex IV or citrate synthase activity, compared to other groups. Mitochondrial function in the gut mucosa from children with ASD was found to be significantly different than other groups who manifested similar GI symptomatology suggesting a unique pathophysiology for GI symptoms in children with ASD. Abnormalities localized to the cecum suggest a role for imbalances in the microbiome, potentially in the production of butyrate, in children with ASD.

  9. Landsat 6 contract signed

    Maggs, William Ward

    A new agreement provides $220 million for development and construction of the Landsat 6 remote sensing satellite and its ground systems. The contract, signed on March 31, 1988, by the Department of Commerce (DOC) and the Earth Observation Satellite (EOSAT) Company of Lanham, Md., came just days after approval of DOC's Landsat commercialization plan by subcommittees of the House and Senate appropriations committees.The Landsat 6 spacecraft is due to be launched into orbit on a Titan II rocket in June 1991 from Vandenburg Air Force Base, Calif. The satellite will carry an Enhanced Thematic Mapper (ETM) sensor, an instrument sensitive to electromagnetic radiation in seven ranges or bands of wavelengths. The satellite's payload will also include the Sea Wide Field Sensor (Sea-WiFS), designed to provide information on sea surface temperature and ocean color. The sensor is being developed in a cooperative effort by EOSAT and the National Aeronautics and Space Administration (NASA). A less certain passenger is a proposed 5-m resolution, three-band sensor sensitive to visible light. EOSAT is trying to find both private financing for the device and potential buyers of the high-resolution imagery that it could produce. The company has been actively courting U.S. television networks, which have in the past used imagery from the European Système Probatoire d'Observation de la Terre (SPOT) satellite for news coverage.

    The Population Council's microbicide gel MZC (also known as PC-1005) containing MIV-150 and zinc acetate dihydrate (ZA) in carrageenan (CG) has shown promise as a broad-spectrum microbicide against HIV, herpes simplex virus (HSV), and human papillomavirus. Previous data show antiviral activity against these viruses in cell-based assays, prevention of vaginal and rectal simian-human immunodeficiency virus reverse transcriptase (SHIV-RT) infection, and reduction of vaginal HSV shedding in rhesus macaques and also excellent antiviral activity against HSV and human papillomavirus in murine models. Recently, we demonstrated that MZC is safe and effective against SHIV-RT in macaque vaginal explants. Here we established models of ex vivo SHIV-RT/HSV-2 coinfection of vaginal mucosa and SHIV-RT infection of rectal mucosa in macaques (challenge of rectal mucosa with HSV-2 did not result in reproducible tissue infection), evaluated antiviral activity of MZC, and compared quantitative polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay readouts for monitoring SHIV-RT infection. MZC (at nontoxic dilutions) significantly inhibited SHIV-RT in vaginal and rectal mucosas and HSV-2 in vaginal mucosa when present during viral challenge. Analysis of SHIV-RT infection and MZC activity by 1-step simian immunodeficiency virus gag quantitative RT-PCR and p27 enzyme-linked immunosorbent assay demonstrated similar virus growth dynamics and MZC activity by both methods and higher sensitivity of quantitative RT-PCR. Our data provide more evidence that MZC is a promising dual compartment multipurpose prevention technology candidate.

    This paper examines the possible relationship between proposed social determinants of morphological ‘complexity’ and how this contributes to linguistic diversity, specifically via the typological nature of the sign languages of deaf communities. We sketch how the notion of morphological complexity, as defined by Trudgill (2011), applies to sign languages. Using these criteria, sign languages appear to be languages with low to moderate levels of morphological complexity. This may partly reflec...

  19. Africa: signs of hope?

    Directory of Open Access Journals (Sweden)

    J.F. Kirsten

    2008-07-01

    Full Text Available The dawning of the 21st century generally brought new hope to African leaders and countless thousands of ordinary citizens of many countries on the continent. The first signs of a new turn of events shone through by the end of the last decade of the previous century. This was manifested by economic growth rates that started to pick up in a number of African states, by pro-democracy movements which in country after country succeeded in replacing authoritarian regimes, and by the winding down and termination of some of Africa’s most devastating wars. The results of this analysis confirm the above-mentioned positive political, economic and conflict trends in Africa. It is clearly a significant turn of events given the well-known political and economic predicament with which Africa is struggling. When this negative legacy and Cold War background of Africa is considered, the importance of present developments is clear to see. The identified heightened sense of purpose among the leaders and peoples of Africa and the changed mood and need among Africans to take charge of their own future that found expression in the New Partnership for Africa’s Development (NEPAD are indeed significant and bode well for the future of the continent. A word of warning here is, however, necessary. Our conduct with Africa must be very cautious and we must guard against over-optimism and the exaggerated belief that Africa is now on a trajectory of sustained development and peace. We cannot generalise about Africa – for that the continent is just too big and diverse from a geographical, cultural, economic and political point of view.

    Pulmonary hypertension (PH) has a poor prognosis. It may be idiopathic or develop secondary to various cardiac and respiratory disorders. The diagnosis of PH is challenging because its signs and symptoms are non-specific and there is no completely reliable non-invasive test for its detection. Most patients with suspected PH or with the non-specific symptoms of PH will undergo computed tomography (CT) as part of their diagnostic work-up and, therefore, it is important for radiologists to be aware of the CT signs that may suggest the diagnosis. This article will review the numerous CT signs of PH describing their individual strengths and weaknesses, and discuss how they may be applied in clinical practice.

    2018-01-01

    Full Text Available Oral verruca vulgaris is caused by human papillomavirus (HPV infection. Verruca vulgaris most frequently occurs on the fingers, toes, soles, and dorsal surfaces of hands and is mostly asymptomatic. Varieties of verrucous and papillary lesions affect the skin as well as oral mucosa which may be either benign or reactive. Common wart is one of the most commonly observed skin growths and a lesion of childhood. Intraoral warts can occur at any age with equal incidence in both genders but are most commonly seen in the third to fifth decade. It is found commonly on the palate followed by lip, tongue, buccal mucosa, and rarely seen on gingiva. Surgical excision with adequate margins is the treatment of choice.

    2016-07-01

    Roseomonas is a genus of pink-pigmented nonfermentative bacilli. These slow-growing, gram-negative cocobacilli form pink-colored colonies on sheep blood agar. They differ from other pink-pigmented nonfermenters, including Methylobacterium, in morphology, biochemical characteristics, and DNA sequence. Roseomonas strains are rarely isolated in clinical laboratories; therefore, we report two cases in order to improve our ability to identify these pathogens. We isolated two strains of Roseomonas mucosa from the venous blood cultures of two patients, an 84-yr-old woman with common bile duct obstruction and a 17-yr-old male with acute myeloid leukemia who had an indwelling central-venous catheter for chemotherapy. The isolated strains were confirmed as R. mucosa by 16S rRNA sequencing.

    Full Text Available Background: Celiac disease (CD is an immune-mediated enteropathy triggered by the ingestion of gluten in genetically susceptible subjects. Although the small intestinal mucosa is the main site of the gut's involvement in CD, other mucosal surfaces belonging to the gastrointestinal tract and the gut-associated lymphoid tissue are known to be affected. Aim: Assuming that the oral mucosa could reflect the histopathological inflammatory alterations of the intestine in CD patients, this study wishes to assess the pattern of T-cell subsets in the oral mucosa of young adults with CD. Methods: A group of 37 patients (age range 20-38 years; female: male ratio 28:9 with CD were enrolled. Out of 37 patients, 19 patients (group A followed a gluten free diet (GFD -2 patients from less than one year; 6 patients between 1 and 5 years; 11 patients more than 5 years- while 18 patients (group B were still untreated. Fifteen healthy volunteers (age range 18-35 years, female: Male ratio 11:4 served as controls for the CD patients. Ethical approval for the research was granted by the Ethics Committee. Biopsy specimens were taken from normal looking oral mucosa. The immunohistochemical investigation was performed with monoclonal antibodies to CD3, CD4, CD8, and γδ-chains T cell receptor (TCR. Results: The T-lymphocytic inflammatory infiltrate was significantly (p < 0.0001 increased in group B (both compared with group A and with the control group. Conclusion: This study confirms the oral cavity to be a site of involvement of CD and its possible diagnostic potentiality in this disease.

    Titanium is the most widely used metal in dental implantology. The release of particles from metal structures into the biologic milieu may be the result of electrochemical processes (corrosion) and/or mechanical disruption during insertion, abutment connection, or removal of failing implants. The aim of the present study is to evaluate tissue response of human oral mucosa adjacent to titanium cover screws. One hundred fifty-three biopsies of the supra-implant oral mucosa adjacent to the cover screw of submerged dental implants were analyzed. Histologic studies were performed to analyze epithelial and connective tissue as well as the presence of metal particles, which were identified using microchemical analysis. Langerhans cells, macrophages, and T lymphocytes were studied using immunohistochemical techniques. The surface of the cover screws was evaluated by scanning electron microscopy (SEM). Forty-one percent of mucosa biopsies exhibited metal particles in different layers of the section thickness. Particle number and size varied greatly among specimens. Immunohistochemical study confirmed the presence of macrophages and T lymphocytes associated with the metal particles. Microchemical analysis revealed the presence of titanium in the particles. On SEM analysis, the surface of the screws exhibited depressions and irregularities. The biologic effects seen in the mucosa in contact with the cover screws might be associated with the presence of titanium or other elements, such as aluminum or vanadium. The potential long-term biologic effects of particles on soft tissues adjacent to metallic devices should be further investigated because these effects might affect the clinical outcome of the implant.

    Caudal regeneration was investigated in decerebrate Anaitides mucosa and in brain-intact individuals. Both groups show an identical capacity to regenerate lost caudal segments. Furthermore there is no difference in males and females. Low temperature (5 °C) inhibits the regeneration of caudal segments, but it is necessary for normal oogenesis. Under conditions of high temperature (15 °C), caudal regeneration is very extensive. At the same time degeneration of most oocytes occurs.

    Odontogenic keratocyst (OKC) of the buccal mucosa, the diagnosis of which is based on subjective histologic evaluation, is a controversial entity of questionable existence. This report describes 2 rare cases of parakeratinized cyst arising from the buccal mucosa. Case 1 was a 60-year-old man with a 3-cm cyst and case 2 was a 16-year-old boy with a microcyst incidentally discovered on histology. Both lesions were essentially identical in histologic appearance and immunophenotype to intraosseous and gingival OKC, but they were clearly different from orthokeratinized odontogenic cysts and buccal mucosal epidermoid cysts. Step sections failed to reveal any kind of odontogenic tissue or skin adnexa in the cyst wall. These microscopic characteristics reflexively lead to the diagnosis of OKC, if the extragingival occurrence in the buccal mucosa cannot be considered. An alternative nonodontogenic origin includes a keratocyst of the skin, ie, an unusual mucosal presentation of cutaneous keratocyst. Because its true nature, either odontogenic or epidermal, cannot be conclusively proven at this time, we propose a more descriptive and noncommittal term, "mucosal keratocyst," for a particular cyst in a buccal location that is morphologically indistinguishable from OKC.

    Endobronchial infection is associated with pulmonary tuberculosis in the majority of cases. We have investigated the adherence of Mycobacterium tuberculosis to the human respiratory mucosa. Organ cultures constructed with human tissue were infected with M. tuberculosis in the presence or absence of mycobacterial fibronectin attachment cell surface proteins and examined by scanning electron microscopy. M. tuberculosis adhered mainly to extracellular matrix (ECM) in areas of mucosal damage, but not to ciliated mucosa, intact extruded cells, basement membrane or collagen fibres. Bacteria also adhered to fibrous but not globular mucus and occasionally to healthy unciliated mucosa, open tight junctions and to extruded cells that had degenerated, exposing their contents. There was a significant reduction (pprotein (FAP) and M. bovis antigen 85B protein, in a concentration dependent manner. The combined effect of FAP and antigen 85B protein was significantly greater than either protein alone. Bacterial adherence to fibrous mucus was not influenced by fibronectin. We conclude that M. tuberculosis adheres to ECM in areas of mucosal damage at least in part via FAP and antigen 85B protein.

    People's online rating behavior can be modeled by user-object bipartite networks directly. However, few works have been devoted to reveal the hidden relations between users, especially from the perspective of signed networks. We analyze the signed monopartite networks projected by the signed user-object bipartite networks, finding that the networks are highly clustered with obvious community structure. Interestingly, the positive clustering coefficient is remarkably higher than the negative clustering coefficient. Then, a Signed Growing Network model (SGN) based on local preferential attachment is proposed to generate a user's signed network that has community structure and high positive clustering coefficient. Other structural properties of the modeled networks are also found to be similar to the empirical networks.

    The identification of an increasing array of highly potent, endogenous peptide and protein factors termed cytokines, that can be efficiently synthesized using recombinant DNA technology, offers exciting new approaches for drug therapy. However, the physico-chemical and biological properties of these agents impose limitations in formulation and development of optimum drug delivery systems as well as on the routes of delivery. Oral mucosa, including the lining of the cheek (buccal mucosa), floor of mouth and underside of tongue (sublingual mucosa) and gingival mucosa, has received much attention in the last decade because it offers excellent accessibility, is not easily traumatized and avoids degradation of proteins and peptides that occurs as a result of oral administration, gastrointestinal absorption and first-pass hepatic metabolism. Peptide absorption occurs across oral mucosa by passive diffusion and it is unlikely that there is a carrier-mediated transport mechanism. The principal pathway is probably via the intercellular route where the major permeability barrier is represented by organized array of neutral lipids in the superficial layers of the epithelium. The relative role of aqueous as opposed to the lipid pathway in drug transport is still under investigation; penetration is not necessarily enhanced by simply increasing lipophilicity, for other effects, such as charge and molecular size, also play an important role in absorption of peptide and protein drugs. Depending on the pharmacodynamics of the peptides, various oral mucosal delivery systems can be designed. Delivery of peptide/protein drugs by conventional means such as solutions has some limitations. The possibility of excluding a major part of drug from absorption by involuntary swallowing and the continuous dilution due to salivary flow limits a controlled release. However these limitations can be overcome by adhesive dosage forms such as gels, films, tablets, and patches. They can localize the

    We have validated differences in DNA methylation levels of candidate genes previously reported to discriminate between normal colon mucosa of patients with colon cancer and normal colon mucosa of individuals without cancer. Here, we report that CpG sites in 16 of the 30 candidate genes selected show significant differences in mean methylation level in normal colon mucosa of 24 patients with cancer and 24 controls. A support vector machine trained on these data and data for an additional 66 CpGs yielded an 18-gene signature, composed of ten of the validated candidate genes plus eight additional candidates. This model exhibited 96% sensitivity and 100% specificity in a 40-sample training set and classified all eight samples in the test set correctly. Moreover, we found a moderate-strong correlation (Pearson coefficients r = 0.253-0.722) between methylation levels in colon mucosa and methylation levels in peripheral blood for seven of the 18 genes in the support vector model. These seven genes, alone, classified 44 of the 48 patients in the validation set correctly and five CpGs selected from only two of the seven genes classified 41 of the 48 patients in the discovery set correctly. These results suggest that methylation biomarkers may be developed that will, at minimum, serve as useful objective and quantitative diagnostic complements to colonoscopy as a cancer-screening tool. These data also suggest that it may be possible to monitor biomarker methylation levels in tissues collected much less invasively than by colonoscopy. ©2014 American Association for Cancer Research.

    The immunotoxic effect of ochratoxin A (OTA) on the intestinal mucosa-associated lymphoid tissue and its cytotoxic action on the intestinal epithelium were studied in broiler chickens experimentally treated with the toxin. From the 7th day of life, 80 male broiler chickens (Ross 308) were randomly divided into four groups of 20 birds each. The three experimental groups (E1-3) were treated with OTA for 28 days (E1: 50 μg/kg body weight [bw]/day; E2: 20 μg/kg bw/day; E3: 1 μg/kg bw/day) and the fourth group served as control. Histological examination of the intestinal mucosa and immunohistochemical staining for identification of CD4+, CD8+, TCR1 and TCR2 lymphocytes in the duodenum, jejunum and ileocaecal junction were performed, and CD4+/CD8+ and TCR1/TCR2 ratios were calculated. OTA toxicity resulted in decreased body weight gain, poorer feed conversion ratio, lower leukocyte and lymphocyte count, and altered intestinal mucosa architecture. After 14 days of exposure to OTA, immunohistochemistry showed a significant reduction of the lymphocyte population in the intestinal epithelium and the lamina propria. After 28 days of exposure, an increase in the CD4+ and CD8+ values in both the duodenum and jejunum of chickens in Groups E1 and E2 was observed, but the TCR1 and TCR2 lymphocyte counts showed a significant reduction. No significant changes were observed in Group E3. The results indicate that OTA induced a decrease in leukocyte and lymphocyte counts and was cytotoxic to the intestinal epithelium and the mucosa-associated lymphoid tissue, altering the intestinal barrier and increasing susceptibility to various associated diseases.

    Full Text Available Mobile online social network (mOSN is a burgeoning research area. However, most existing works referring to mOSNs deal with static network structures and simply encode whether relationships among entities exist or not. In contrast, relationships in signed mOSNs can be positive or negative and may be changed with time and locations. Applying certain global characteristics of social balance, in this paper, we aim to infer the unknown relationships in dynamic signed mOSNs and formulate this sign inference problem as a low-rank matrix estimation problem. Specifically, motivated by the Singular Value Thresholding (SVT algorithm, a compact dictionary is selected from the observed dataset. Based on this compact dictionary, the relationships in the dynamic signed mOSNs are estimated via solving the formulated problem. Furthermore, the estimation accuracy is improved by employing a dictionary self-updating mechanism.

    2018-01-01

    This paper examines the possible relationship between proposed social determinants of morphological 'complexity' and how this contributes to linguistic diversity, specifically via the typological nature of the sign languages of deaf communities. We sketch how the notion of morphological complexity, as defined by Trudgill (2011), applies to sign languages. Using these criteria, sign languages appear to be languages with low to moderate levels of morphological complexity. This may partly reflect the influence of key social characteristics of communities on the typological nature of languages. Although many deaf communities are relatively small and may involve dense social networks (both social characteristics that Trudgill claimed may lend themselves to morphological 'complexification'), the picture is complicated by the highly variable nature of the sign language acquisition for most deaf people, and the ongoing contact between native signers, hearing non-native signers, and those deaf individuals who only acquire sign languages in later childhood and early adulthood. These are all factors that may work against the emergence of morphological complexification. The relationship between linguistic typology and these key social factors may lead to a better understanding of the nature of sign language grammar. This perspective stands in contrast to other work where sign languages are sometimes presented as having complex morphology despite being young languages (e.g., Aronoff et al., 2005); in some descriptions, the social determinants of morphological complexity have not received much attention, nor has the notion of complexity itself been specifically explored.

RESULTS: It was found that the degree of EPF (through the epimetaphyseal angle presented a statistically significant inverse relationship with the presence of FAI over the mean follow-up period of this study. In other words, the patients with symptoms of FAI presented lesser degrees of slippage. This can be explained by the fact that the types of impingement that occurs in cases of EPF (i.e. cam impaction or inclusion depends on the degree of slippage, and these present different clinical forms and chronology. The ROM did not present any relationship with FAI. CONCLUSION: There is a relationship between the degree of slippage and the presence of clinical-radiological FAI after EPF.

    Sign language users recruit physical properties of visual motion to convey linguistic information. Research on American Sign Language (ASL) indicates that signers systematically use kinematic features (e.g., velocity, deceleration) of dominant hand motion for distinguishing specific semantic properties of verb classes in production ( Malaia & Wilbur, 2012a) and process these distinctions as part of the phonological structure of these verb classes in comprehension ( Malaia, Ranaweera, Wilbur, & Talavage, 2012). These studies are driven by the event visibility hypothesis by Wilbur (2003), who proposed that such use of kinematic features should be universal to sign language (SL) by the grammaticalization of physics and geometry for linguistic purposes. In a prior motion capture study, Malaia and Wilbur (2012a) lent support for the event visibility hypothesis in ASL, but there has not been quantitative data from other SLs to test the generalization to other languages. The authors investigated the kinematic parameters of predicates in Croatian Sign Language ( Hrvatskom Znakovnom Jeziku [HZJ]). Kinematic features of verb signs were affected both by event structure of the predicate (semantics) and phrase position within the sentence (prosody). The data demonstrate that kinematic features of motion in HZJ verb signs are recruited to convey morphological and prosodic information. This is the first crosslinguistic motion capture confirmation that specific kinematic properties of articulator motion are grammaticalized in other SLs to express linguistic features.

    MR is the most useful imaging method in evaluating the anatomic changes of the optic chiasm (OC). The purpose of this study is to investigate the relationship between the OC displacement and visual manifestations. We retrospectively reviewed 44 patients who showed displacement of OC on brain MR. The pattern of OC displacement was classified into 3 groups according to following criteria: group A included the patients with OC displacement only due to empty sella; group B represented the patients with OC displacement by a lesion and the border between the lesion and OC was distinct; and group C was the patients with OC displacement by a lesion and had a indistinct border or thinning of the OC. Visual symptoms and signs were noted in 12 patients and the most common sign was bitemporal hemianopsia. In group A (7 patients), the visual symptoms and signs were seen in only one patient (14%), in whom contracted visual fields persisted since previous pituitary apoplexy had developed. In group B (30 patients), the visual symptoms and signs were seen in 4 patients (13%) who had tumorous conditions except one case of cysticercosis. In group C (7 patients), the visual symptoms and signs were seen in all patients (100%). The more OC is compressed, the more the prevalence of visual symptoms and signs increases. However, there was no correlation between the occurrence of visual symptoms and the presence of OC displacement only without compression

    Blend sign (BS) and black hole sign (BHS) on non-contrast computed tomography (NCCT) and spot sign (SS) on CT-angiography (CTA) are indicators of early hematoma expansion in spontaneous intracerebral hemorrhage (ICH). However, their independent contributions to outcome have not been well explored. In this retrospective study, inclusion criteria were: 1) spontaneous ICH and 2) NCCT and CTA performed on admission within 6 hours after onset of symptoms. Discharge outcome was dichotomized as good (modified Rankin Scale [mRS] 0-3) and poor (mRS 4-6) outcomes. The impacts of BHS, BS and SS on outcome were assessed in univariate and multivariable logistic regression models. Of 182 patients with spontaneous ICH, 26 (14.3%) presented with BHS, 37 (20.3%) with BS and 39 (21.4%) with SS. There was a substantial correlation between SS and BS (κ=0.701) and a moderate correlation between SS and BHS (κ=0.424). In univariable logistic regression, higher baseline hematoma volume ( P <0.001), intraventricular hemorrhage ( P =0.002) and the presence of BHS/BS/SS (all P <0.001) on admission CT scan were associated with poor outcome. Multivariable analysis identified intraventricular haemorrhage (odds ratio [OR] 2.22 per mL, P =0.022), baseline hematoma volume (OR 1.03 per mL, P <0.001) and SS on CTA (OR 11.43, P <0.001) as independent predictors of poor outcome, showing that SS compared to BS and BHS was more powerful to predict poor outcome. The NCCT BHS and BS are correlated with the CTA SS and are reliable predictors of poor outcome in patients with ICH. Of the CT variables indicating early hematoma expansion, SS on CTA was the most reliable outcome predictor. However, given their correlation with SS on CTA, BS and BHS on NCCT can be useful for predicting outcome if CTA is not obtainable.

    Full Text Available The gut microbiota is an environmental factor that determines renewal of the intestinal epithelium and remodeling of the intestinal mucosa. At present, it is not resolved if components of the gut microbiota can augment innate immune sensing in the intestinal epithelium via the up-regulation of Toll-like receptors (TLRs. Here, we report that colonization of germ-free (GF Swiss Webster mice with a complex gut microbiota augments expression of TLR2. The microbiota-dependent up-regulation of components of the TLR2 signaling complex could be reversed by a 7 day broad-spectrum antibiotic treatment. TLR2 downstream signaling via the mitogen-activated protein kinase (ERK1/2 and protein-kinase B (AKT induced by bacterial TLR2 agonists resulted in increased proliferation of the small intestinal epithelial cell line MODE-K. Mice that were colonized from birth with a normal gut microbiota (conventionally-raised; CONV-R showed signs of increased small intestinal renewal and apoptosis compared with GF controls as indicated by elevated mRNA levels of the proliferation markers Ki67 and Cyclin D1, elevated transcripts of the apoptosis marker Caspase-3 and increased numbers of TUNEL-positive cells per intestinal villus structure. In accordance, TLR2-deficient mice showed reduced proliferation and reduced apoptosis. Our findings suggest that a tuned proliferation response of epithelial cells following microbial colonization could aid to protect the host from its microbial colonizers and increase intestinal surface area.

    síntomas preoperatorios de los pacientes con HDL. Los signos y síntomas evaluados fueron el dolor lumbar, el dolor en la pierna, los disturbios motores y sensitivos y el signo de Lasègue. CONCLUSIÓN: el índice de éxito de la cirugía de los pacientes con HDL refractarios al tratamiento clínico se correlaciona con la ausencia de lumbalgia, la presencia de ciatalgia con tiempo de evolución de hasta seis meses, el déficit sensitivo presente de forma aislada o asociado al déficit motor y la presencia de signo de Lasègue positivo en el periodo preoperatorio.INTRODUCTION: lumbar disc herniation (LDH is currently a prevalent pathology which leads to physical, psychological and social limitations for the patient. The most frequent signs and symptoms are lumbocyatalgia, motor and sensitive disorders and Lasègue's sign. In patients with LDH refractory to medical treatment, discectomy is the standard procedure to improve the symptoms. OBJECTIVES: to study the prognostic relevance of signs and symptoms in patients with LDH refractory to medical treatment. METHODS: a survey was performed, in the main biomedical databases, for articles that studied the percentage of improvement and prognostic value of the preoperative signs and symptoms of patients with LDH. The signs and symptoms evaluated were lumbar pain, leg pain, motor and sensitive disorders and Lasègue's sign. CONCLUSION: the success rate in surgery of patients with LDH refractory to medical treatment is correlated with the absence of lumbalgia, the presence of cyatalgia over up to six months, the sensitive deficit present alone or associated with motor deficit and the presence of positive Lasègue's sign during the preoperative period.

    While mucoceles of the oral mucosa are relatively common, multiple mucous retention cysts have not previously been reported. In this article two such cases, in which numerous minor salivary gland ducts had dilated to the point of cyst formation, are described. The number of individual cysts exceeded 100 in each case. Since it is clear that these cysts formed as a result of dilatation of salivary ducts, it would seem that either the ducts were blocked by altered secretion or there was an acquired or congenital weakness in their structure.

    Amalgam tattoos are common exogenous pigmented lesions of the oral mucosa occurring mainly by inadvertent placement of amalgam particles into soft tissues. The diagnosis of amalgam tattoo is simple, usually based on clinical findings associated with presence or history of amalgam fillings removal. Intraoral X-rays may be helpful in detecting amalgam-related radiopacity. In cases where amalgam tattoo cannot be differentiated from other causes of oral pigmentation, a biopsy should be performed. This article deals with an extensive amalgam tattoo lesion which required a biopsy for a definitive diagnosis.

    To determine the accuracy of preoperative urinary symptoms, urinalysis, computed tomography (CT) and cystoscopic findings for the diagnosis of urinary bladder invasion in patients with colorectal cancer. Records of patients with colorectal cancer and a suspicion of bladder invasion, who underwent tumor resection with partial or total cystectomy between 2002 and 2013 at the Faculty of Medicine Siriraj Hospital, were reviewed. Correlations between preoperative urinary symptoms, urinalysis, cystoscopic finding, CT imaging and final pathological reports were analyzed. This study included 90 eligible cases (71% male). The most common site of primary colorectal cancer was the sigmoid colon (44%), followed by the rectum (33%). Final pathological reports showed definite bladder invasion in 53 cases (59%). Significant features for predicting definite tumor invasion were gross hematuria (OR 13.6, sensitivity 39%, specificity 73%), and visible tumor during cystoscopy (OR 5.33, sensitivity 50%, specificity 84%). Predictive signs in CT imaging were gross tumor invasion (OR 7.07, sensitivity 89%, specificity 46%), abnormal enhancing mass at bladder wall (OR 4.09, sensitivity 68%, specificity 66%), irregular bladder mucosa (OR 3.53, sensitivity 70%, specificity 60% ), and loss of perivesical fat plane (OR 3.17, sensitivity 81%, specificity 43%). However, urinary analysis and other urinary tract symptoms were poor predictors of bladder involvement. The present study demonstrated that the most relevant preoperative predictors of definite bladder invasion in patients with colorectal cancer are gross hematuria, a visible tumor during cystoscopy, and abnormal CT findings.

    The aim was to characterize the transport of fluorescein isothiocyanate (FITC)-labeled dextran and insulin with different resoluble compounds for peptides and proteins through buccal mucosa. The penetration rate of insulin molecules through porcine buccal mucosa (a nonkeratinized epithelium, comparable to human buccal mucosa) was investigated by measuring transbuccal fluxes and by analyzing the distribution of the fluorescent probe in the rabbit buccal mucosa epithelium, using confocal laser scanning microscopy for visualizing permeation pathways. The confocal images of the distribution pattern of FITC-dextran and FITC-insulin showed that the paracellular route is the major pathway of FITC-dextran through buccal mucosa epithelium, the intra-cellular route is the major pathway of FITC-insulin through buccal mucosa epithelium. The permeation rate can be increased by co-administration of soybean phosphatidylcholine (SPC).

    Objective: To explore the relation between p53 genetic polymorphisms and radiotherapy-induced acute injury of mucosa of oral cavity mucosa. Methods: The total of 56 patients with NPC treated by radiotherapy alone or with chemoradiotherapy synchronically were genotyped for the p53 codon 72 pro-Arg SNP using PCR-RFLP assays, and were ranked according to the acute injury of oral cavity mucosa. Results: There was no difference in acute injury of oral cavity mucosa between the p53 Pro allele carriers and the other carriers (P>0.05); the high single dose (P<0.01) and concomitant chemoradiotherapy (P<0.05) resulted in increase in acute injury of oral cavity mucosa. Conclusion: Those results suggest that p53 SNP may not associate with radiotherapeutic acute injury of oral cavity mucosa. (authors)

    Mucosa-mimetic materials are synthetic substrates which aim to replace animal tissue in mucoadhesion experiments. One potential mucosa-mimetic material is a hydrogel comprised of N-acryloyl-d-glucosamine and 2-hydroxyethylmethacrylate, which has been investigated as a surrogate for animal mucosae in the mucoadhesion testing of tablets and solution formulations. This study aims to investigate the efficacy of this mucosa-mimetic material in the testing of thermogelling semi-solid formulations, which transition from solution to gel upon warming. Two methods for assessing mucoadhesion have been used; tensile testing and a flow-through system, which allow for investigation under dramatically different conditions. It was found that the mucosa-mimetic material was a good surrogate for buccal mucosa using both testing methods. This material may be used to replace animal tissue in these experiments, potentially reducing the number of laboratory animals used in studies of this type. Copyright © 2017 Elsevier B.V.

    The aim of this study was to measure the thickness of the hard palate and its overlying mucosa using cone-beam computed tomography (CBCT), for purposes of miniscrew placement. The sample comprised 36 CBCT scans of patients aged 12 to 52 years from a database of the Orthodontics Department of the Federal University of Rio de Janeiro. Paracoronal views of the palatal region were reconstructed at 4, 8, 16 and 24 mm posterior to the incisive foramen. In each reconstruction measurements were taken at the suture, 3 mm and 6 mm bilaterally to it. Wilcoxon's test verified the differences between the selected regions. Total bone height decreased from the anterior to the posterior region. In cross sections 4, 16 and 24, bone height decreased from the suture laterally to the 3 mm region and then increased in the 6 mm region. The cortical thickness does not seem to be a concern because it presented a mean thickness of at least 1 mm at all sites evaluated. The measurements of the mucosa thickness decreased from lateral to median and from anterior to posterior regions. The most suitable areas for miniscrew placement in the palate are located 4 mm posterior to the incisive foramen, in the median or paramedian regions 3 mm adjacent to the suture. (author)

    A case of heterotopic gastric mucosa in the common bile duct, cystic duct and gallbladder is reported in a 3-year-old girl with abdominal pain and jaundice. Abdominal US and CT showed dilatation of the biliary tree and a well-defined mass in the common bile duct that narrowed its lumen. The gallbladder was contracted in both examinations. The common bile duct and the gallbladder were resected and a choledochojejunostomy was performed. Although gastric heterotopy has been described throughout the entire length of the gastrointestinal tract, it is a very uncommon finding in the gallbladder and extremely rare in the biliary tree. A firm diagnosis of gastric heterotopia is based on the presence of fundal mucosa replete with parietal and chief cells. To our knowledge, this is the fifth reported case of heterotopic gastric tissue within the common bile duct, and the first to describe the US and CT findings. A relevant literature review and brief outline of the histological and radiological features are included in the discussion. (orig.)

    The aim of the present study was to perform a morphological evaluation by immunofluorescence of biomarkers of keratinocyte intercellular adhesion, and of differentiation in the tongue mucosa of burning mouth syndrome patients (BMS), compared with a control group. A prospective blinded evaluation of tongue mucosal specimens processed for light microscopy was performed. Intercellular adhesion was evaluated by investigating the expression of desmoglein 1, desmoglein 3, and of occludin. Keratin 10 and keratin 14 (markers of epithelial differentiation) were also evaluated, as keratin 16 (marker for activated keratinocytes after epithelial injury). Apoptotic cascade was investigated by p53 and activated caspase-3 expression. The basal membrane integrity was analysed through laminin immunoreactivity. In both groups, a preserved three-dimensional architecture of the tongue was observed. Desmoglein 1 and desmoglein 3 epithelial distributions were similar in the desmosomes of patients and control subjects. Again, keratin 10 immunoreactivity and distribution pattern of keratin 14 in the epithelial compartment was similar in both groups. In control samples, keratin 16 immunoreactivity was scant throughout the epithelium with a punctuate and scattered cytoplasmic labelling. In contrast, in all BMS patients keratinocyte cytoplasm was homogeneously labelled for keratin 16, with a more intense staining than controls. Furthermore, keratin 16 staining progressively decreased proceeding towards the most superficial epithelial layers. The results of this study are consistent with and support the clinically normal features of oral mucosa in BMS, and suggest that keratin 16 may be involved in the cell mechanisms underlying the syndrome occurrence.

    Celiac disease (CD), a systemic autoimmune disorder that typically involves duodenal mucosa, can also affect other intestinal areas. Duodenal and oral mucosa organ culture has already been demonstrated as a reliable procedure to identify CD. The present study investigated gluten-dependent immunological activation of colonic mucosa in CD patients. We took advantage of the numerous colonoscopies performed for various clinical conditions or only for defensive medicine. Forty-four patients with gastrointestinal symptoms or in need of colorectal cancer screening were divided into patients with serum anti-endomysium (EMA) and anti-tissue transglutaminase (anti-tTG) antibody positive results (Group A), patients with serum antibody negative results (Group B), and patients with inflammatory bowel disease (IBD) (Group C). The autoantibodies EMA and anti-tTG were evaluated in supernatants of cultured sigmoid and duodenal biopsies from patients on a gluten-containing diet. In Group A, EMA and anti-tTG resulted positive in all duodenal culture supernatants. In sigmoid culture supernatants, EMA and anti-tTG were detected in 12/16 (75 %) and 13/16 (81.3 %) patients, respectively. In Group B, none of the 17 patients showed EMA and anti-tTG positive results in both duodenal and sigmoid cultures. In Group C, all 11 patients presented EMA negative results in sigmoid cultures. Only in one patient, anti-tTG were detectable in the sigmoid culture supernatant, as expected in cases of IBD. Data confirm that the gluten-dependent immunological activation affects more intestinal tracts with different degrees of involvement, suggesting that the organ culture of colonic biopsies could represent a new tool to opportunistically detect CD.

    Changes in mucin production and dyscrinia are common features of inflammation in chronic obstructive pulmonary disease (COPD). Immunohistochemical assessment of MUC-2, MUC-3, MUC-4 expression in the integumentary epithelium, goblet cells, the epithelium of mucous glands and stroma fusiform cells of the bronchial mucosa of COPD patients during an infectious and noninfectious exacerbation was performed. 30 patients with stage III COPD were enrolled to the study. Patients were divided into 2 groups: group A - 14 patients with non-infectious acute exacerbation of COPD (AECOPD) and group B - 16 patients with infectious AECOPD. Fiberoptic bronchoscopy (FBS) and in vivo bronchial biopsy of bronchial mucosa were implemented to determine the extent and nature of bronchial inflammation. The optical density of specific color in bronchial structures was assessed using immunohistochemical staining to MUC-2, -3 and -4 antigens by means of primary monoclonal antibodies to these proteins, and visualization system Dako EnVision + System, Peroxidase (AEC). We detected that in different types of bronchial mucosa epithelial cells, during acute infectious exacerbation, a decrease of antigens MUC-2 and MUC-3 expression of a various degree may occur. This phenomenon in the stroma fusiform cells in AECOPD may be a sign of epithelial-mesenchymal transition, that may play a role in the development of an inflammatory process and progression of fibrosis in COPD.

    The automotive industry has been always a driving force for all economies. Despite of its beneficial meaning to every society it brings also many issues including wide area of road safety. The latter has been enforced by the increasing number of cars and the dynamic development of the traffic as a whole. Road signs and traffic lights are crucial in context of good traffic arrangement and its fluency. Traffic designers are used to treat horizontal road signs independently of vertical signs. However, modern light sources and growing flexibility in shaping optical systems create opportunity to design more advanced and smart solutions. In this paper we present an innovative, multidisciplinary approach that consists in tight interdependence of different traffic signals. We describe new optical systems together with their influence on the perception of the road user. The analysis includes maintenance and visibility in different weather conditions. A special attention has been focused on intersections of complex geometry.

Most of these problems come down to establishing simple rules, rules that can easily be applied every...... – or are they homonyms?" and so on. Very often such questions demand further research and can't be answered sufficiently through a simple standard formula. Therefore lexicographic work often seems like an endless series of compromises. Another source of compromise arises when you set out to decide which information...... this dilemma, as we see DTS learners and teachers as well as native DTS signers as our target users. In the following we will focus on four problem areas with particular relevance for the sign language lexicographer: Sign representation Spoken languague equivalents and mouth movements Example sentences Partial...

  5. Characteristic CT signs in oligodendrogliomas

    Computed tomography offers valuable aid for improving the diagnostic capabilities for oligodendrogliomas. The authors have attempted to determine more precisely the CT characteristic signs for this type of tumor and to establish criteria for predicting malignancy grade. They can conclude that calcifications are the main signs which lead to the diagnosis of oligodendroglioma, as the most usual calcifying glioma. This finding was known before the CT era, but with the CT one can be more exact with regard to form, growth, number and density of the calcifications and especially the smallest of them, which are not to be seen on the conventional X-ray examination. The cyst formation is another feature of oligodendroglioma. The occurrence of contrast enhancement and cyst formation are the most characteristic signs of malignancy. (C.F.)

    The European Society of Immunodeficiency (ESID) developed 6 warning signs to promote the awareness of adult primary immunodeficiency disease (PID). To screen adult patients for the presence of PID using these 6 warning signs to determine the effectiveness of this protocol. Questions related to the ESID warning signs for adult PID were added to the standard outpatient clinic file system and asked of 3,510 patients who were admitted to our clinic for any reason. Patients with signs and/or suspicion of PID based on their medical history underwent immunologic investigation. In total, 24 patients were diagnosed as having a PID. The most common reason that patients with PID were admitted was frequent infection (n=18 [75%]), and the most common PID subgroup was common variable immunodeficiency (n=12 [50%]). Twenty patients with PID had at least one positive finding according to the ESID warning signs. Two patients with gastrointestinal concerns and 2 with dermatologic symptoms were also diagnosed as having a PID, although they did not have any of the ESID warning signs. The ESID warning signs do not specify the need for symptoms to diagnose a PIDs and do not include a comprehensive list of all signs and symptoms of PIDs. As a result, more than infection-centric questions are needed to identify adult patients with immunodeficiencies. Copyright © 2016 American College of Allergy, Asthma & Immunology.

    Full Text Available The aim of our work was to evaluate the long-term changes in symptoms (median 42 months and to analyze data for any negative predictive factors for the application of the procedure, in patients who underwent to urethroplasty with dorsal buccal mucosa graft. During the period from 2010 to 2015 27 patients were examined. Than they underwent urethroplasty using dorsal buccal mucosa graft (graft of 4 x 2.5 cm. The evaluation of symptoms has been addressed through the application of the IPSS Quality of Life Questionnaire (International Prostatic Symptoms Score and the evaluation of urinary flow has been carried out by a comparative analysis between the pre- and post-operative uroflowmetry. As our study has shown, data obtained by the screening tests in the post-operative follow-up indicate that there is an increase in the maximum flow of urine until 1 month after surgery. The results in the long-term follow-up are different because they show a partial reduction of the maximum flow although it is maintained around an average value of 23 ml/s being still higher than the maximum flow in the pre-operative period. According to our results it follows that there is a low failure rate of the procedure after a median of 42 months. Only in patients with urethral stenosis longer than 2 cm, a lower long term success is achieved. From what we could observe, this length of the stenosis seems to be the only negative predictive factor for long-term maintenance of a good Quality of Life in patients undergoing the procedure. The results obtained from our study confirm literature data according to which, the gold standard for 2-cm long bulbar urethral stricture whose lumen is well preserved with circumferential spongiofibrosis limited to 1-2 mm is the dorsal graft urethroplasty with buccal mucosa that in our study showed success rates higher of 80% after a median follow up of 42 months and a percentage of relapse-free patients of 82.1% ( median 3.5 years.

    BACKGROUND Early hematoma growth is associated with poor outcome in patients with spontaneous intracerebral hemorrhage (ICH). The swirl sign (SS) and the black hole sign (BHS) are imaging markers in ICH patients. The aim of this study was to compare the predictive value of these 2 signs for early hematoma growth. MATERIAL AND METHODS ICH patients were screened for the appearance of the 2 signs within 6 h after onset of symptoms. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the 2 signs in predicting early hematoma growth were assessed. The accuracy of the 2 signs in predicting early hematoma growth was analyzed by receiver-operator analysis. RESULTS A total of 200 patients were enrolled in this study. BHS was found in 30 (15%) patients, and SS was found in 70 (35%) patients. Of the 71 patients with early hematoma growth, BHS was found on initial computed tomography scans in 24 (33.8%) and SS in 33 (46.5%). The sensitivity, specificity, PPV, and NPV of BHS for predicting early hematoma growth were 33.8%, 95.3%, 80.0%, and 72.0%, respectively. The sensitivity, specificity, PPV, and NPV of SS were 46.5%, 71.3%, 47.0%, and 71.0%, respectively. The area under the curve was 0.646 for BHS and 0.589 for SS (P=0.08). Multivariate logistic regression showed that presence of BHS is an independent predictor of early hematoma growth. CONCLUSIONS The Black hole sign seems to be good predictor for hematoma growth. The presence of swirl sign on admission CT does not independently predict hematoma growth in patients with ICH.

    Clinical lateralizing signs are the phenomena which can unequivocally refer to the hemispheric onset of epileptic seizures. They can improve the localization of epileptogenic zone during presurgical evaluation, moreover, their presence can predict a success of surgical treatment. Primary sensory phenomena such as visual aura in one half of the field of vision or unilateral ictal somatosensory sensation always appear on the contralateral to the focus. Periictal unilateral headache, although it is an infrequent symptom, is usually an ipsilateral sign. Primary motor phenomena like epileptic clonic, tonic movements, the version of head ubiquitously appear contralateral to the epileptogenic zone. Very useful lateralization sign is the ictal hand-dystonia which lateralizes to the contralateral hemisphere in nearly 100%. The last clonus of the secondarily generalized tonic-clonic seizure lateralizes to the ipsilateral hemisphere in 85%. The fast component of ictal nystagmus appears in nearly 100% on the contralateral side of the epileptic focus. Vegetative symptoms during seizures arising from temporal lobe such as spitting, nausea, vomiting, urinary urge are typical for seizures originating from non-dominant (right) hemisphere. Ictal pallor and cold shivers are dominant hemispheric lateralization signs. Postictal unilateral nose wiping refers to the ipsilateral hemispheric focus compared to the wiping hand. Ictal or postictal aphasia refers to seizure arising from dominant hemisphere. Intelligable speech during complex partial seizures appears in non-dominant seizures. Automatism with preserved consciousness refers to the seizures of non-dominant temporal lobe.

    IgG4-related disease is a systemic disease characterized by lesions with IgG4 positive plasma cell infiltration in the involved organs and a raised serum IgG4 level. We report a patient of 70-year-old male presented orbital inflammation of IgG4-related disease. The patient developed right eye pain, double vision, and reduced eye sight. MRI image revealed mild right ocular proptosis and swelling of right carvenous sinus, bilateral intraorbital extraocular muscles and right optic nerve. Right optic nerve showed ring-like enhancement. IgG4-related disease was suspected with increased serum IgG4 level of 355 mg/dl, mediastinal lymphadenopathy and prostate enlargement. Transbronchial lung biopsy and prostate needle biopsy were administered with negative results. The eye related symptoms resolved with time, but serum IgG4 continuously increased. IgG4-related disease was diagnosed by nasal mucosa biopsy, which showed IgG4 positive plasma cells within the inflammatory infiltrate. This report emphasizes the usefulness of nasal mucosa biopsy for the diagnosis of IgG4 related disease with lesions difficult to approach.

    The ''Dimple sign'' has been coined by Baltaxe et al. in 1974 and was said to be useful angiographic sign of avascular tumor. Similar dimple can be seen in the margin of the liver on CT examination of the hepatic tumors. We called this hepatic dimple sign and its clinical usefulness on CT examination was studied with 133 cases of hepatic tumors. Among 133 cases, there were 68 cases of hepatocellular carcinoma, 57 cases of metastatic liver tumor, 5 cases of hemangioma of the liver and 3 cases of hepatoblastoma. Hepatic dimple sign was recognized on 2 cases of metastatic liver tumor, 1 case of hemangioma, and 1 case of carcinoma of the gallbladder with hepatic infiltration. Cases experienced in the affiliated hospitals were also studied. A case of hepatocellular carcinoma and a case of metastatic liver tumor were evaluated. These tumors were relativly large measuring over 5cm in the greatest diameter and low density areas were apparent on plain CT. Therefore, dimples in the hepatic margin seen in CT scan did not contribute to the diagnostic accuracy of the liver tumor in these cases. (author).

    2014-01-01

    Full Text Available Background/Aim. Uncomplicated diverticular disease (UDD is a frequent condition in adults. The pathogenesis of symptoms remains unknown. Bacteria are able to interact with Toll-like receptors (TLRs and to induce inflammation through both innate immunity and T-cell recruitment. We investigated the pattern of TLRs 2 and 4 and the intestinal homing in patients with UDD before and after a course of Rifaximin. Methods. Forty consecutive patients with UDD and 20 healthy asymptomatic subjects were enrolled. Among UDD patients, 20 were assigned to a 2-month course of treatment with Rifaximin 1.2 g/day for 15 days/month and 20 received placebo. Blood sample and colonic biopsies were obtained from patients and controls. The samples were collected and analyzed at baseline and at the end of treatment. Flow cytometry was performed using monoclonal antibodies (CD3, CD4, CD8, CD103, TCR-gamma/delta, CD14, TLR2, and TLR4. Results. In UDD, TLR2 and TLR4 expression on immune cell subpopulations from blood and mucosa of the affected colon are altered as compared with controls. Rifaximin treatment induced significant modifications of altered conditions. Conclusions. Our data show the role of TLRs in the development of inflammation in UDD. TLRs distribution is altered in UDD and these alterations are reversed after antibiotic treatment. This trial is registered with ClinicalTrials.gov: NCT02068482.

    Li, Ruili; Yang, Mingfei

    2017-01-01

    Hematoma expansion (HE) is a major determinant of a poor outcome in patients with a spontaneous intracerebral hemorrhage (sICH). The blend sign and the black hole sign are distinguished from non-contrast CT (NCCT) in patients with sICH, and both are independent neuroimaging predictors of HE. The purpose of the current study was to compare the value of the two signs in the prediction of HE. We retrospectively analyzed clinical and neuroimaging data from 228 patients with sICH who were treated at our hospital between August 2015 and September 2017. NCCT of the brain was performed upon admission (within 6 h of the onset of symptoms) to identify the blend sign and the black hole sign. HE was determined based on CT during a follow-up 24 h later. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) with which the blend sign and the black hole sign predicted HE were calculated. Receiver operating characteristic (ROC) curve analysis was performed in order to compare the accuracy of the two signs in predicting HE. The blend sign was identified in 46 patients (20.2%) and the black hole sign was identified in 38 (16.7%) based on NCCT of the brain upon admission. Of the 65 patients with HE, the blend sign was noted in 28 and the black hole sign was noted in 22. The blend sign had a sensitivity of predicting HE of 43.1%, a specificity of 89.0%, a PPV of 60.9%, and an NPV of 79.7%. In contrast, the black hole sign had a sensitivity of predicting HE of 33.9%, a specificity of 90.2%, a PPV of 57.9%, and an NPV of 77.4%. The area under the ROC curve was 0.660 for the blend sign and 0.620 for the black hole sign (p = 0.516). In conclusion, the blend sign and the black hole sign on CT are both good predictors of HE in patients with sICH, though the blend sign seems to have a higher level of accuracy.

    Full Text Available Synovial sarcoma (SS is a rare malignant neoplasm that arises most commonly in joint capsules and articular tendons, but its relationship to the synovium is not always obvious. Synovial sarcoma is a malignant soft tissue tumor representing 5.6% to 10% of all soft tissue sarcomas. They are termed SS because of their histologic resemblance to the synovium, but they rarely involve a synovial structure and are thought to arise from pluripotential mesenchymal cells. The tumor usually occurs in close association with tendon sheaths, bursae, and joint capsules, primarily in the para-articular regions of the extremities, with approximately 9% occurring in the head and neck region. Synovial sarcoma has been reported rarely in the oral cavity. We report a very rare case of Synovial sarcoma of the buccal mucosa in a 24-year-old male patient.

    This study describes the mucosa-associated lymphoid tissue (MALT) in odontocetes from the Brazilian coast and freshwater systems. Seven species were evaluated and tissue samples were analyzed by light, scanning and transmission electron microscopy, and immunohistochemistry. Laryngeal tonsil was a palpable oval mass located in the larynx, composed of a lymphoepithelial complex. Dense collections of lymphocytes were found in the skin of male fetus and calf. Clusters of lymphoid tissue were found in the uterine cervix of a reproductively active juvenile female and along the pulmonary artery of an adult female. Lymphoid tissues associated with the gastrointestinal tract were characterized by diffusely arranged or organized lymphocytes. The anal tonsil was composed of an aggregate of lymphoid tissue occurring exclusively in the anal canal, being composed of squamous epithelium branches. MALT was present in different tissues and organic systems of cetaceans, providing constant protection against mucosal pathogens present in their environment. © 2016 Wiley Periodicals, Inc.

    A dose-surviving fraction curve representing the response of the mouse colonic mucosa to single doses of 137 Cs gamma radiation was obtained from the results of a multifraction in vivo colony assay. Construction of the curve required an estimated of the average number of clonogens initially present per colonic crypt. The estimated clonogen count (88) was determined by a statistical method based on the use of doses per fraction common to different fractionation protocols. Parameters for the LQ and TC models of cell survival were obtained by weighted least-squares fits to the data. A comparison of the survival characteristics of cells from the mouse colonic and jejunal crypts suggested that the epithelium of the colon is less radiosensitive than that of the jejunum. (author)

    Merkel cell carcinoma (MCC) is an uncommon relatively aggressive neuroendocrine dermal neoplasm first described in 1972 as a tumor of the sun exposed skin. Although most MCC affect the skin of the head and neck, rare primarily oral mucosal cases have been documented. Merkel cells are nondendritic neuroendocrine cells that are found not only in the skin but also the oral mucosa and give rise to MCC. Neuroendocrine cells may be found as aggregates in organs or as diffuse or isolated cells within organs and their epithelial lining. They contain peptide hormones and biogenic amines and occur in two forms: dendritic, which are not associated with nerve fibers and non-dendritic, which are associated with nerve fibers. Merkel cells as well as MCC express simple epithelium-type Cytokeratins (8, 18, 19, 20), neurosecretory substances; chromogranin A, synaptophysin, neuron-specific enolase (NSE), adhesion molecules, and villin (intermediate filament). Though weakly, they also express neural markers such as S-100 protein. Cytokeratin 20, and Cluster of differentiation 56, are the two key diagnostic markers for Merkel cells and MCC. Etiology includes UV radiation, the recently described Merkel cell polyomavirus, and long term systemic immunosuppression. The cutaneous and mucosal variants of MCC are considered aggressive tumors with a high risk for local recurrence and metastasis and should be considered in the differential diagnosis of head and neck mucosal lesions. We present two cases of primary Merkel cell carcinoma, one on the buccal mucosa and the other on the lower lip, and discuss the salient histologic, immunohistochemical and clinical features.

Thirty-six birds were randomly distributed in a 3 x 3 factorial arrangement, considering 3 probiotics and prebiotics sources in the diet. There were 9 treatments with 4 repetitions. Diet treatments were: 1 - Control (without growth promoters; 2 - Bacillus subtilis-based probiotic (Pro 1; 3 - Probiotic (Pool based on Lactobacillus acidophilus and casei, Streptococcus lactis and faecium, Bifidobacterium bifidum and Aspergillus oryzae (Pro 2; 4 - Prebiotic based on Phosphorylated Mannanoligosaccharide (MOS and Organic Acidifier (OA (Pre 1; 5 - MOS-based prebiotic (Pre 2; 6 - Pro 1 + Pre 1; 7 - Pro 1 + Pre 2; 8 - Pro 2 + Pre 1; 9 - Pro 2 + Pre 2. Higher villus height (VH (p<0.01 were seen in the duodenum of birds fed diets without prebiotics, whereas birds fed Bacillus subtilis-based probiotic and birds fed prebiotic based on MOS and OA showed higher VH (p<0.01 in jejunum and ileum. Greater crypt depths (CD (p<0.01 were observed in the duodenum, jejunum and ileum of birds receiving B. subtilis, and in the duodenum and jejunum of birds fed diets without prebiotics. Significant interaction (p<0.01 between the evaluated factors was seen for both, VH and CD, in the three intestinal portions. Greater VH was obtained in duodenum, jejunum and ileum with the use of probiotics and prebiotics and greater CD with the use of probiotics, in relation to the control group. There was no difference in villus density (VD between birds fed diets without additives or diets containing probiotics and prebiotics. Nevertheless, there was a significant interaction (p<0.05 between the evaluated factors for VD in the duodenum. Concluding, beneficial effects were seen in histological indexes of the intestinal mucosa with the use of probiotics and prebiotics at 21 days of age.

    There is currently no standard method for delineating the oral mucosa and most attempts are oversimplified. A new method to obtain anatomically accurate contours of the oral mucosa surfaces was developed and applied to 11 patients. This is expected to represent an opportunity for improved toxicity modelling of oral mucositis

    Transmucosal delivery is a suitable route for insulin non-injection administration. In order to understand how insulin passes through mucosa with soybean-lecithin as an enhancing absorption. The penetration rate of insulin molecular through porcine buccal mucosa was investigated by measuring transbuccal fluxes in the Ussing Chambers. The imaging morphology of rabbits buccal mucosa was analyzed by using non-contact mode atomic force microscopy. The permeation rate can be increased by co-administration of soybean-lecithin. Untreated buccal mucosa showed relatively smooth surface characteristics, with many small crater-like pits and indentations spread over mucosa surfaces. Buccal mucosa that had been treated with 1.0% (w/v) sodium deoxycholic acid (pH 7.4) appeared to much more indentations characteristic, which treated with 2.5% (w/v) soybean-lecithin (pH 7.4) and 2.5% (w/v) Azone or laurocapram (pH 7.4) appeared rather different, the surface mucosa treated with soybean-lecithin emulsion showed a fine, rippling effect whereas those exposed to Azone display a more coarse, undulating surface feature. As a result of that Azone could damage the surface of the buccal mucosa, but soybean-lecithin could not. This study demonstrated that soybean-lecithin is a better and safer enhancer for insulin transmucosal delivery.

    In maxillary Le Fort I type osteotomy the detachment of the nasal mucosa should be done carefully. Piezoelectric surgery contributed much to increase the safety of osteotomies, despite the initial advantage of minimizing the risk of injury in nervous tissue, mainly in bilateral sagittal split osteotomy; we use the piezoelectric device for the initial detachment of the nasal mucosa in the maxillary osteotomy.

    To investigate the occurrence and protection of skin/mucosa contamination among obstetrician and gynecologist. By random, stratified, and clustered sampling, 219 obstetrician and gynecologist were selected. 210 valid questionnaires were collected, efficiency is 95.89%. 110 obstetrician and gynecologist come from tertiary hospitals, 100 come from secondary hospitals. A self-administered questionnaire on skin/mucosa contamination was employed to gauge the implementation of protection, types and working links of skin/mucosa contamination. Of the respondents, only 14.76% (31/210) and 5.24% (11/210) adhered to proper hand washing and wearing protective glasses within nearly 1 year in practical work. Of the respondents, 73.81% (155/210) had experienced the skin/mucosa contamination during their vocation, 50.95% (107/210) occurred sharps injuries, 45.71% (96/210) occurred damaged skin contamination, and 43.33% (91/210) occurred mucosa contamination. Sharps injuries mainly occurred when abdominal operation (45.71%, 96/120), damaged skin contamination mainly occurred when gynecological examination (21.43%, 45/210), and mucosa contamination mainly occurred when midwifery (37.14%, 78/210). The implementation of protective measures is inadequate and incidence of skin/mucosa contamination is higher among obstetrician and gynecologist. Therefore, occupational protection education should focus on different types and working links of skin/mucosa contamination. At the same time, strict supervision and management system should be established.

    Mechanotransduction caused by vocal fold vibration could possibly be an important factor in the maintenance of extracellular matrices and layered structure of the human adult vocal fold mucosa as a vibrating tissue after the layered structure has been completed. Vocal fold stellate cells (VFSCs) in the human maculae flavae of the vocal fold mucosa are inferred to be involved in the metabolism of extracellular matrices of the vocal fold mucosa. Maculae flavae are also considered to be an important structure in the growth and development of the human vocal fold mucosa. Tension caused by phonation (vocal fold vibration) is hypothesized to stimulate the VFSCs to accelerate production of extracellular matrices. A human adult vocal fold mucosa unphonated over a decade was investigated histopathologically. Vocal fold mucosa unphonated for 11 years and 2 months of a 64-year-old male with cerebral hemorrhage was investigated by light and electron microscopy. The vocal fold mucosae (including maculae flavae) were atrophic. The vocal fold mucosa did not have a vocal ligament, Reinke's space or a layered structure. The lamina propria appeared as a uniform structure. Morphologically, the VFSCs synthesized fewer extracellular matrices, such as fibrous protein and glycosaminoglycan. Consequently, VFSCs appeared to decrease their level of activity.

  2. Effects of antihistamine on up-regulation of histamine H1 receptor mRNA in the nasal mucosa of patients with pollinosis induced by controlled cedar pollen challenge in an environmental exposure unit

    Full Text Available In the present study, we examined the effects of antihistamine on the up-regulation of H1R mRNA in the nasal mucosa of patients with pollinosis induced by controlled exposure to pollen using an environmental exposure unit. Out of 20 patients, we designated 14 responders, whose levels of H1R mRNA in the nasal mucosa were increased after the first pollen exposure and excluded 6 non-responders. Accordingly, the first exposure to pollen without treatment significantly induced both nasal symptoms and the up-regulation of H1R mRNA in the nasal mucosa of the responders. Subsequently, prophylactic administration of antihistamine prior to the second pollen exposure significantly inhibited both of the above effects in the responders. Moreover, the nasal expression of H1R mRNA before the second pollen exposure in the responders pretreated with antihistamine was significantly decreased, as compared with that before the first pollen exposure without treatment. These findings suggest that antihistamines suppressed histamine-induced transcriptional activation of H1R gene in the nasal mucosa, in addition to their blocking effect against histamine on H1R, resulting in a decrease of nasal symptoms. These findings further suggest that by their inverse agonistic activity, antihistamines suppress the basal transcription of nasal H1R in the absence of histamine in responders.

    In the present work, we have compared the resistance of the 90 Degree-Sign , 180 Degree-Sign , and 360 Degree-Sign domain walls in the presence of external magnetic field. The calculations are based on the Boltzmann transport equation within the relaxation time approximation. One-dimensional Neel-type domain walls between two domains whose magnetization differs by angle of 90 Degree-Sign , 180 Degree-Sign , and 360 Degree-Sign are considered. The results indicate that the resistance of the 360 Degree-Sign DW is more considerable than that of the 90 Degree-Sign and 180 Degree-Sign DWs. It is also found that the domain wall resistance can be controlled by applying transverse magnetic field. Increasing the strength of the external magnetic field enhances the domain wall resistance. In providing spintronic devices based on magnetic nanomaterials, considering and controlling the effect of domain wall on resistivity are essential.

    Full Text Available A 13-year-old male was operated for a space occupying lesion in the brain. A noncontrast computed tomography scan done in the late postoperative period showed massive subdural air collection causing compression of bilateral frontal lobes with widening of interhemispheric fissure and the frontal lobes acquiring a peak like configuration - causing tension pneumocephalus-"Mount Fuji sign." Tension pneumocephalus occurs when air enters the extradural or intradural spaces in sufficient volume to exert a mass or pressure effect on the brain, leading to brain herniation. Tension pneumocephalus is a surgical emergency, which needs immediate intervention in the form of decompression of the cranial cavity by a burr hole or needle aspiration. The Mount Fuji sign differentiates tension pneumocephalus from pneumocephalus.

    Relations between users on social media sites often reflect a mixture of positive (friendly) and negative (antagonistic) interactions. In contrast to the bulk of research on social networks that has focused almost exclusively on positive interpretations of links between people, we study how the interplay between positive and negative relationships affects the structure of on-line social networks. We connect our analyses to theories of signed networks from social psychology. We find that the c...

    In teenagers with perennial allergic rhinitis, exposure to tobacco cigarette smoke increases the count of eosinophils in the nasal mucosa; the recruitment of eosinophils arises from the combined action of a number of cellular and molecular signals, including eotaxin. To assess the effect of exposure to tobacco cigarette smoke on the count of immunoreactive cells to eotaxin-1 and eosinophils on the nasal mucosa of children and teenagers with perennial allergic rhinitis. In a cross-sectional study, forty-four patients were evaluated (aged 7-19 years old): 22 with and 22 with no exposure to tobacco cigarette smoke. After replying to 2 validated questionnaires, on Asthma and Allergies in Childhood and on the severity of nasal symptoms, nasal mucosal samples were obtained by scraping the middle one-third of the inferior turbinates. Then counts of immunoreactive cells to eotaxin-1 and eosinophils were assessed by immunohistochemistry. Patients with exposure to tobacco cigarette smoke showed higher cell counts of both eotaxin-1 and eosinophils than patients with no exposure to the smoke, with no correlation between the two variables. However, both counts, of eotaxin-1 and eosinophils, were related to the cotinine/creatinine ratio. Exposure to tobacco cigarette smoke can increase eotaxin-1 and the count of eosinophils in the nasal mucosa of young patients with perennial allergic rhinitis.

    2008-01-01

    The need for Single Sign On has always been restricted by the absence of cross platform solutions: a single sign on working only on one platform or technology is nearly useless. The recent improvements in Web Services Federation (WS-Federation) standard enabling federation of identity, attribute, authentication and authorization information can now provide real extended Single Sign On solutions. Various solutions have been investigated at CERN and now, a Web SSO solution using some parts of WS-Federation technology is available. Using the Shibboleth Service Provider module for Apache hosted web sites and Microsoft ADFS as the identity provider linked to Active Directory user, users can now authenticate on any web application using a single authentication platform, providing identity, user information (building, phone...) as well as group membership enabling authorization possibilities. A typical scenario: a CERN user can now authenticate on a Linux/Apache website using Windows Integrated credentials, and his Active Directory group membership can be checked before allowing access to a specific web page

    Background: Radiotherapy in cancer of the head and neck induces cutaneous and mucosal reactions. These must be carefully assessed and documented to control the accuracy of individual treatment, the overall toxicity of particular treatment schedules, the efficacy of prophylaxis and treatment and to determine the adequate therapy of treatment sequelae depending on the severity of the reactions. The accurate classification of lesions according to internationally accepted schedules (WHO/RTOG/CTC) is indispensable for the comparison of radiotherapy treatment results and efficacy of supportive care. Methods: While the treatment of cancer depends on tumor stage and medical circumstances of the patient and is more or less standardized, prophylaxis and treatment of side-effects is highly variable. Discussing an optimized prophylaxis and therapy of oral mucositis, the problem of accurate classification and documentation emerged. The verbal description of mucosal lesions is open to many subjective interpretations. Photographic documentation seems a suitable method to optimize the grading of toxicity. Results: A photographic survey of typical lesions for each grade of toxicity is a tool to reach several aims in one step. Toxicity of an individual patient may be compared with representative photographic examples in daily routine to decide quickly on the grade of toxicity. Subjective differences due to intra- and interpersonal variability of the evaluating radiooncologist will be reduced. The efficacy of trof treatment can be proven by accurate documentation. Randomized clinical studies concerning prophylaxis and treatmen mucositis will provide more reliable results if evaluation of toxicity grading is standardized by photographs. Conclusions: Photographic documentation of lesions of the oral mucosa might be the best means to reduce interindividual subjectivity in grading. It is a valuable appendix to standard classification systems and only concerns the visible signs of mucosal

    Lower socioeconomic status (SES) is associated with a higher risk of late-stage cancer diagnosis. A number of explanations have been advanced for this, but one which has attracted recent attention is lower patient knowledge of cancer warning signs, leading to delay in help-seeking. However, although there is psychometric evidence of SES differences in knowledge of cancer symptoms, no studies have examined differences in 'cancer suspicion' among people who are actually experiencing a classic warning sign. A 'health survey' was mailed to 9771 adults (⩾50years, no cancer diagnosis) with a symptom list including 10 cancer 'warning signs'. Respondents were asked if they had experienced any of the symptoms in the past 3months, and if so, were asked 'what do you think caused it?' Any mention of cancer was scored as 'cancer suspicion'. SES was indexed by education. Nearly half the respondents (1732/3756) had experienced a 'warning sign', but only 63/1732 (3.6%) mentioned cancer as a possible cause. Lower education was associated with lower likelihood of cancer suspicion: 2.6% of respondents with school-only education versus 7.3% with university education suspected cancer as a possible cause. In multivariable analysis, low education was the only demographic variable independently associated with lower cancer suspicion (odds ratio (OR)=0.34, confidence interval (CI): 0.20-0.59). Levels of cancer suspicion were low overall in this community sample, and even lower in people from less educated backgrounds. This may hinder early symptomatic presentation and contribute to inequalities in stage at diagnosis. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

  14. In vitro culturing of porcine tracheal mucosa as an ideal model for investigating the influence of drugs on human respiratory mucosa.

    It has been previously shown that fresh mucosa from different mammals could serve as raw material for in vitro culturing with the differentiation of cilia, which are the most important morphological structures for the function of the mucociliary system. Increasing legal restrictions on the removal of human tissue and changing surgical techniques have led to a lack of fresh human mucosa for culturing. Most of the animals that have been used as donors up to now are genetically not very close to human beings and must all be sacrificed for such studies. We, therefore, established a modified system of culturing mucosa cells from the trachea of pigs, which is available as a regular by-product after slaughtering. With respect to the possibility of developing "beating" cilia, it could be shown that the speed of cell proliferation until adhesion to the coated culture dishes, the formation of conjunctions of cell clusters and the proliferation of cilia were comparable for porcine and human mucosa. Moreover, it could be demonstrated that the porcine cilia beat frequency of 7.57 +/- 1.39 Hz was comparable to the human mucosa cells beat frequency of 7.3 +/- 1.4 Hz and that this beat frequency was absolutely constant over the investigation time of 360 min. In order to prove whether the reaction to different drugs is comparable between the porcine and human cilia, we initially tested benzalkonium chloride, which is known to be toxic for human cells, followed by naphazoline, which we found in previous studies on human mucosa to be non-toxic. The results clearly showed that the functional and morphological reactions of the porcine ciliated cells to these substances were similar to the reaction we found in the in vitro cultured human mucosa.

    Oral squamous cell carcinoma is the most common malignant lesion of the oral cavity, and it involves various molecular mechanisms. The development of oral squamous cell carcinoma is influenced by the host immune cells, such as eosinophils. The present study was conducted to compare the presence of eosinophils in normal mucosa, dysplastic mucosa, and oral squamous cell carcinoma by -hematoxylin- eosin staining, Congo red staining, and epidermal growth factor-like (EGF-like) module containing a mucin-like hormone receptor1 (EMR1) immunohistochemical marker. In this cross-sectional study, 60 paraffinized samples were selected, consisting of 20 normal mucosae, 20 dysplastic mucosae, and 20 squamous cell carcinoma samples. After confirmation of the diagnosis, the mean number of eosinophils was evaluated by hematoxylin-eosin, Congo red, and immunohystochemical staining techniques. The data were analyzed by SPSS-10 software using the Kruskal-Wallis and Friedman tests. The results showed that the number of eosinophils in dysplastic mucosa was significantly higher than the number in normal mucosa, and the number of eosinophils in squamous cell carcinoma was significantly higher than the number in dysplastic mucosa in all staining techniques (p<0.001). Moreover, the comparison of staining techniques showed a significantly higher number of eosinophils in EMR1immunohistochemicalmarker than were observed when Congo red and hematoxylin - eosin (H&E) staining techniques were used (p<0.001). It can be argued that eosinophil contributes to the identification of lesions that have a higher potential of malignant transformation. Moreover, eosinophil can be suggested as an indicator in the differentiation of oral lesions in cases with borderline diagnosis and in targeted molecular therapy.

    Signs indicating the end of a focal seizure with loss of awareness and/or responsiveness but without progression to focal or generalized motor symptoms are poorly defined and can be difficult to determine. Not recognizing the transition from ictal to postictal behaviour can affect seizure reporting accuracy by family members and may lead to delayed or a lack of examination during EEG monitoring, erroneous seizure localization and inadequate medical intervention for prolonged seizure duration. Our epilepsy monitoring unit database was searched for focal seizures without secondary generalization for the period from 2007 to 2011. The first focal seizure in a patient with loss of awareness and/or responsiveness and/or behavioural arrest, with or without automatisms, was included. Seizures without objective symptoms or inadequate video-EEG quality were excluded. A total of 67 patients were included, with an average age of 41.7 years. Thirty-six of the patients had seizures from the left hemisphere and 29 from the right. All patients showed an abrupt change in motor activity and resumed contact with the environment as a sign of clinical seizure ending. Specific ending signs (nose wiping, coughing, sighing, throat clearing, or laughter) were seen in 23 of 47 of temporal lobe seizures and 7 of 20 extra-temporal seizures. Seizure ending signs are often subtle and the most common finding is a sudden change in motor activity and resumption of contact with the environment. More distinct signs, such as nose wiping, coughing or throat clearing, are not specific to temporal lobe onset. A higher proportion of seizures during sleep went unexamined, compared to those during wakefulness. This demonstrates that seizure semiology can be very subtle and arousals from sleep during monitoring should alert staff. Patient accounts of seizure frequency appear to be unreliable and witness reports need to be taken into account. [Published with video sequences].

    Early hematoma growth is a devastating neurological complication after intracerebral hemorrhage. We aim to report and evaluate the usefulness of computed tomography (CT) black hole sign in predicting hematoma growth in patients with intracerebral hemorrhage. Patients with intracerebral hemorrhage were screened for the presence of CT black hole sign on admission head CT performed within 6 hours after onset of symptoms. The black hole sign was defined as hypoattenuatting area encapsulated within the hyperattenuating hematoma with a clearly defined border. The sensitivity, specificity, and positive and negative predictive values of CT black hole sign in predicting hematoma expansion were calculated. Logistic regression analyses were used to assess the presence of the black hole sign and early hematoma growth. A total of 206 patients were enrolled. Black hole sign was found in 30 (14.6%) of 206 patients on the baseline CT scan. The black hole sign was more common in patients with hematoma growth (31.9%) than those without hematoma growth (5.8%; Phole sign in predicting early hematoma growth were 31.9%, 94.1%, 73.3%, and 73.2%, respectively. The time-to-admission CT scan, baseline hematoma volume, and the presence of black hole sign on admission CT independently predict hematoma growth in multivariate model. The CT black hole sign could be used as a simple and easy-to-use predictor for early hematoma growth in patients with intracerebral hemorrhage. © 2016 American Heart Association, Inc.

We planned to determine whether any basal IVCCI range would be able to predict persistent or worsening clinical congestion found at the end of subsequent follow up (i.e. after 1-2 months of oral optimized therapy. For this purpose, the patients were subdivided by three groups according to the basal IVCCI value: ≤ 15% (13 pts, 16 - 40% (21 pts and > 40% (20 pts.Several clinical criteria of congestion were compared across the three groups and subsequently entered in the Cox multivariate model. RESULTS: Multivariate predictors of high congestion score were jugular venous distension (HR: 13,38 95% C.I.: 2,13 - 84 p = 0,0059 and rales (HR: 11 95% C.I : 1,45 - 83,8 p = 0,0213. IVCCI ≤ 15% was always associated with high congestion score at the second visit; but IVCCI ≤ 15% failed to predict high congestion score at the second visit. CONCLUSION: In CHF setting, low IVCCI did not reliably predict high congestion score. Nevertheless, the cluster with IVCCI ≤ 15% was always found associated with signs and symptoms from both right and left-sided decompensated CHF.

    The essential targets of dry eye disease (DED) treatments include both objective signs and subjective symptoms. However, due to the numerous subjective symptoms, it is understandable why little association has been found between the signs and symptoms. Although psychological influences on the subjective symptoms have been reported, little is known about the influence of personality traits. The present study analyzed the relationship between the signs/symptoms of DED and the personality traits of patients using a cross-sectional design. We examined 56 DED patients (mean age; 62.4 ± 12.9, range 34-85 years) visiting the outpatient clinic of the Department of Ophthalmology at the Nippon Medical School Hospital in Tokyo, Japan. Objective signs evaluated included the Schirmer I test, tear breakup time (BUT), fluorescein and lissamine green staining, and tear osmolality. Subjective symptoms were assessed by the Ocular Surface Disease Index (OSDI) and Dry Eye-Related Quality-of-Life Score (DEQS) questionnaires. For personality traits, the Big Five personality traits model analysis was used. Correlations between the objective signs, subjective symptoms, and personality traits were analyzed. A significant correlation was found between the neuroticism in the Big Five Personality Inventory and the symptoms assessed by the DEQS (r = -0.35, p personality traits. The results of our current study suggest that the personality of the patient, which appears to be the basis of various psychological factors, can have some impact on the subjective symptoms. This may be one of the reasons why there has been little association noted between the signs and symptoms of DED.
