Idiom comprehension was assessed in 10 aphasic patients with semantic deficits by means of a string-to-picture matching task. Patients were also submitted to an oral explanation of the same idioms, and to a word comprehension task. The stimuli of this last task were the words following the verb in the idioms. Idiom comprehension was severely…

To investigate spatial responses by aphasic patients during language tasks, 63 aphasics (21 severe, 21 moderate, and 21 mild) were administered two kinds of auditory pointing tasks-word tasks and sentence tasks-in which the spatial conditions of the stimuli were controlled. There were significantly fewer correct responses on the right side of a space than on the left side in both the word and sentence tasks, but the left deviation of correct responses was more prominent in the sentence task than in the word task. Additionally, the severe aphasics exhibited a prominent leftward deviation that may have been the result of deficits in rightward attention controlled by the left hemisphere. This phenomenon also seems to reflect the directional attention that is subserved by the right hemisphere, which attends to the left side of a space and, less predominantly, the right side of a space.

Objective To outline the audiological findings of aphasic patients after cerebrovascular accidents. Methods This is a cross-sectional study performed between March 2011 and August 2012 in the Speech, Language, and Hearing Pathology Department of the Universidade Federal de São Paulo. A total of 43 aphasic subjects (27 men) were referred for audiological evaluation after stroke, with mean age of 54.48 years. Basic audiological evaluation tests were performed, including pure tone audiometry, speech audiometry (speech recognition threshold and word recognition score), immittance measures (tympanometry and contralateral acoustic reflex), and transient otoacoustic emissions. Results Sensorineural hearing loss was prevalent (78.6%). Speech recognition threshold and word recognition score were not obtained in some patients because they were unable to perform the task. Hearing loss was a common finding in this population. Conclusion Comprehension and/or oral emission disruptions in aphasic patients after stroke compromised conventional speech audiometry, resulting in the need for changes in the evaluation procedures for these patients.

Aphasic patients with reading impairments frequently substitute incorrect real words for target words when reading aloud. Many of these word substitutions have substantial orthographic overlap with their targets and are classified as ''visual errors'' (i.e., sharing 50% of targets' letters in the same relative position). Fifteen chronic aphasic…

A globally aphasic patient was trained on a computerized visual communication system. His ability to comprehend reversible locative prepositional phrases after training was studied and compared with the performance of Broca's aphasics on a similar task. This patient's ability to generalize symbols for actions was also investigated. The results demonstrate our patient's capacity to master a formal visual syntax in the absence of natural language and illustrate how this capacity may be used successfully in a visual communication system. A problem in generalizing symbols for actions is demonstrated, suggesting that certain heuristic and cueing capabilities in the approach may be helpful.

Quantitative assessment of 50 patients with closed head injury disclosed that anomic errors and word finding difficulty were prominent sequelae as nearly half of the series had defective scores on tests of naming and/or word association. Aphasic disturbance was associated with severity of brain injury as reflected by prolonged coma and injury of the brain stem. PMID:1011017

Idiom comprehension in 15 aphasic patients was assessed with three tasks: a sentence-to-picture matching task, a sentence-to-word matching task and an oral definition task. The results of all three tasks showed that the idiom comprehension in aphasic patients was impaired compared to that of the control group, and was significantly affected by the…

The ability to understand ambiguous idioms was assessed in 15 aphasic patients with preserved comprehension at a single word level. A string-to-word matching task was used. Patients were requested to choose one among four alternatives: a word associated with the figurative meaning of the idiom string; a word semantically associate with the last constituent of the idiom string; and two unrelated words. The results showed that patients' performance was impaired with respect to a group of matched controls, with patients showing a frontal and/or temporal lesion being the most impaired. A significant number of semantically associate errors were produced, suggesting an impairment of inhibition mechanisms and/or of recognition/activation of the idiomatic meaning.

Background Co-speech gestures are omnipresent and a crucial element of human interaction by facilitating language comprehension. However, it is unclear whether gestures also support language comprehension in aphasic patients. Using visual exploration behavior analysis, the present study aimed to investigate the influence of congruence between speech and co-speech gestures on comprehension in terms of accuracy in a decision task. Method Twenty aphasic patients and 30 healthy controls watched videos in which speech was either combined with meaningless (baseline condition), congruent, or incongruent gestures. Comprehension was assessed with a decision task, while remote eye-tracking allowed analysis of visual exploration. Results In aphasic patients, the incongruent condition resulted in a significant decrease of accuracy, while the congruent condition led to a significant increase in accuracy compared to baseline accuracy. In the control group, the incongruent condition resulted in a decrease in accuracy, while the congruent condition did not significantly increase the accuracy. Visual exploration analysis showed that patients fixated significantly less on the face and tended to fixate more on the gesturing hands compared to controls. Conclusion Co-speech gestures play an important role for aphasic patients as they modulate comprehension. Incongruent gestures evoke significant interference and deteriorate patients’ comprehension. In contrast, congruent gestures enhance comprehension in aphasic patients, which might be valuable for clinical and therapeutic purposes. PMID:26735917

We investigated whether six aphasics and six normal subjects could binaurally fuse two slightly differing frequencies of constant amplitude. The aphasics were subdivided into two groups: (1) two men who had had mild cerebrovascular accidents (CVAs) during the past 15 months; (2) four men who had had severe CVAs during the last 15 months. Two tones of different frequency levels but equal in intensity were presented dichotically to the subjects at 40 dB sensation level. All subjects had normal hearing at 500 Hz (0 to 25 dB). All six normal subjects and the two aphasics who had had mild CVAs could hear the binaural beats. The four aphasics who had had severe CVAs could not hear them. A 2 X 2 design resulting from this study was compared using chi2 test with Yates correction and was found to be significantly different (P less than .05). Two theories are presented to explain these findings: the "depression theory" and the "temporal time-sequencing theory." Therapeutic implications are also discussed relative to cerebral and/or brain stem involvement in the fusion of binaural stimuli.

The Sonority Dispersion Principle (Clements, 1990) states that the sharper the rise in sonority between the beginning of the syllable and the nucleus, the better the syllable. So far evidence in favour of this principle has been derived mainly from the distributional properties of syllable types and, to a lesser extent, from language acquisition. The case of DB, presented in this study, provides strong evidence that the Sonority Dispersion Principle also applies to an explanation of aphasic errors and revives Jakobson's idea that the same principles of complexity can explain the distribution of syllables, language acquisition, and language loss (Jakobson, 1941, 1968). Although some evidence that sonority constraints aphasic errors has been presented before, this is the first study reporting systematic effects of sonority-based complexity in aphasia.

Experimental studies have often reported close associations between rapid auditory processing and language competency. The present study was aimed at improving auditory comprehension in aphasic patients following specific training in the perception of temporal order (TO) of events. We tested 18 aphasic patients showing both comprehension and TO perception deficits. Auditory comprehension was assessed by the Token Test, phonemic awareness and Voice-Onset-Time Test. The TO perception was assessed using auditory Temporal-Order-Threshold, defined as the shortest interval between two consecutive stimuli, necessary to report correctly their before-after relation. Aphasic patients participated in eight 45-minute sessions of either specific temporal training (TT, n=11) aimed to improve sequencing abilities, or control non-temporal training (NT, n=7) focussed on volume discrimination. The TT yielded improved TO perception; moreover, a transfer of improvement was observed from the time domain to the language domain, which was untrained during the training. The NT did not improve either the TO perception or comprehension in any language test. These results are in agreement with previous literature studies which proved ameliorated language competency following the TT in language-learning-impaired or dyslexic children. Our results indicated for the first time such benefits also in aphasic patients.

Because it generally took over an hour to administer the Porch Index of Communicative Ability (PICA), a shorter but comparable version of the test was developed. The original test was designed to quantify aphasic patients' ability level on common communicative tasks and consisted of 18 ten-item subtests. Each item resulted in a proficiency rating,…
In a multilingual country such as India, the probability that clinicians may not have command over different languages used by aphasic patients is very high. Since formal tests in different languages are limited, assessment of people from diverse linguistic backgrounds presents speech- language pathologists with many challenges. With a view to…

The human turn-taking system regulates the smooth and precise exchange of speaking turns during face-to-face interaction. Recent studies investigated the processing of ongoing turns during conversation by measuring the eye movements of noninvolved observers. The findings suggest that humans shift their gaze in anticipation to the next speaker before the start of the next turn. Moreover, there is evidence that the ability to timely detect turn transitions mainly relies on the lexico-syntactic content provided by the conversation. Consequently, patients with aphasia, who often experience deficits in both semantic and syntactic processing, might encounter difficulties to detect and timely shift their gaze at turn transitions. To test this assumption, we presented video vignettes of natural conversations to aphasic patients and healthy controls, while their eye movements were measured. The frequency and latency of event-related gaze shifts, with respect to the end of the current turn in the videos, were compared between the two groups. Our results suggest that, compared with healthy controls, aphasic patients have a reduced probability to shift their gaze at turn transitions but do not show significantly increased gaze shift latencies. In healthy controls, but not in aphasic patients, the probability to shift the gaze at turn transition was increased when the video content of the current turn had a higher lexico-syntactic complexity. Furthermore, the results from voxel-based lesion symptom mapping indicate that the association between lexico-syntactic complexity and gaze shift latency in aphasic patients is predicted by brain lesions located in the posterior branch of the left arcuate fasciculus. Higher lexico-syntactic processing demands seem to lead to a reduced gaze shift probability in aphasic patients. This finding may represent missed opportunities for patients to place their contributions during everyday conversation.
From the first research on aphasia, it has been shown that, in addition to verbal communication disorders, aphasic patients often have difficulty on non-verbal cognitive tasks, which can actually be solved without the use of language. In this survey, I will discuss in a historical perspective the different interpretations provided by classical and contemporary authors to explain this puzzling observation. First, I will take into account the different positions of classical authorities on this topic, starting from the first debates (mainly based on anatomo-clinical observations) on the organisation of language in the brain. Then, I will attempt to summarize the work of authors who have tackled this complex issue more recently, in systematic investigations using methods drawn from experimental psychology, to clarify the meaning of non-verbal cognitive disorders in aphasia. Finally, in the last part of the survey, I will discuss the interpretation of proponents of the 'semantic hub' hypothesis who have tried to analyse and explain the differences between the non-verbal semantic defects of patients with semantic dementia and aphasic stroke patients. The hypothesis which assumes that most non-verbal cognitive disorders observed in aphasic patients are due to a preverbal conceptual disorder, which cannot be attributed to a loss of semantic representations but rather to a defect in their controlled retrieval, seems substantially confirmed. Nevertheless, two main issues must still be clarified. The first is that some of the non-verbal cognitive defects of aphasic patients seem due to the negative influence of language disturbances on abstract non-verbal cognitive activities, rather than to a preverbal conceptual disorder. The second issue concerns the exact nature and the neuroanatomical correlates of the defective controlled retrieval of unimpaired conceptual representations, which should subsume most of the non-verbal cognitive disorders of aphasic patients.

Due to the fact that the phonetic, morphological and syntactic structures of the Turkish language differ significantly from other European languages, the translated forms of the currently available aphasia assessment batteries are not adequate for Turkish-speaking aphasic patients. The aim of this study was to assess the validity and reliability of the Ege Aphasia Test that we have developed. The test, which includes the 8 subtests of praxia, spontaneous language, auditory and verbal comprehension, repetition, naming, reading, writing and calculating, was applied into 100 aphasic patients, 40 dysarthric patients and 40 healthy subjects. All test-retest intra-class correlation coefficients were found to be excellent (ICC = 0.99). The Cronbach's coefficients ranged from 0.71 to 0.91. All the subtests showed significantly greater scores in aphasic patients (p < 0.05). Significant correlations were found between the subtests and corrected total score (p < 0.05). Finally, the Ege Aphasia Test has an acceptable validity and reliability. It seems to be a promising battery for evaluation of aphasia in the Turkish language, which is spoken mainly in Turkey and in the surrounding regions. We believe that this study will pioneer the development of aphasia rehabilitation in these countries and contribute to future studies.

Delivering aphasia therapy via telecommunication may provide a means to deliver intensive therapy in a cost-effective way. Teletherapy, remotely-administered (language) treatment, may support the repetitive drill practices that people with chronic aphasia need to perform when learning to compensate for their lasting language difficulties. The use of teletherapy may allow speech and language pathologists (SLPs) to focus in-person sessions more strongly on the generalisation of therapy effects to daily life. This single subject study is an investigation whether a teletherapy application called e-REST meets the criteria of accessibility, user-friendliness, as well as effectiveness. e-REST, the teletherapy version of the Dutch and adapted Reduced Syntax Therapy, teaches chronically aphasic speakers of Dutch who experience difficulties in sentence production to convey their messages in a kind of telegraphic style. The results obtained suggest that it is reasonable to conduct a larger study into the user-friendliness, accessibility, effectiveness, and cost-effectiveness of e-REST.

Because the Galveston Orientation and Amnesia Test (GOAT) requires oral or written response, it risks misclassifying as amnestic aphasic patients who are not, in fact, amnestic. To correct for possible classification errors due to anomia, a modified multiple-choice format of the GOAT (AGOAT) was developed. The average GOAT score of 10 control nonaphasic head-injured patients suggested that an AGOAT score of 90 corresponds to the standard GOAT cutoff of 75 for resolution of posttraumatic amnesia (PTA). Using this criterion, 8 of 15 aphasic head-injured patients who technically were classified as amnestic on the GOAT were classified as nonamnestic on the AGOAT.

Two severely aphasic patients were compared in their abilities to comprehend and produce locative prepositional phrases and reversible S-V-O sentences using English and C-VIC, a computer-based iconographic communication system. One patient demonstrated a significant dissociation between his performance in interpreting symbol order in C-VIC prepositional phrases vs. S-V-O sentences. Patients were able to comprehend order in C-VIC S-V-O sentences significantly better than they were able to assign symbol order when they produced these sentences. These data suggest that the procedures for assigning thematic roles to nouns in sentences are at least partially distinct for comprehension and production and that the ordering of nouns around prepositions involves conceptual processes distinct from those involved in ordering nouns around verbs.

The Japanese language is represented by two different codes: syllabic and logographic while Portuguese employs an alphabetic writing system. Studies on bilingual Portuguese-Japanese individuals with acquired dyslexia therefore allow an investigation of the interaction between reading strategies and characteristics of three different writing codes. The aim of this study was to examine the differential impact of an acquired brain lesion on the reading of the logographic, syllabic and alphabetic writing systems of a bilingual Portuguese-Japanese aphasic patient (PF). Results showed impaired reading in the logographic system and when reading irregularly spelled Portuguese words but no effects on reading regular words and nonwords in syllabic and alphabetic writing systems. These dissociations are interpreted according to a multi-route cognitive model of reading assuming selective damage in the lexical route can result in acquired dyslexia across at least three different writing codes.

Aphasia is a common consequence of stroke; it is estimated that about two-thirds of aphasic patients will develop depression in the first year after the stroke. Treatment of post-stroke depression (PSD) is challenging due to the adverse effects of pharmacotherapy and difficulties in evaluating clinical outcomes, including aphasia. Transcranial direct current stimulation (tDCS) is a novel treatment that may improve clinical outcomes in the traditionally pharmacotherapy-refractory PSD. Our aim was to evaluate the safety and efficacy of tDCS for patients with PSD and with aphasia. The Stroke Aphasic Depression Questionnaire (SADQ) and the Aphasic Depression Rating Scale (ADRS) were used to evaluate the severity of PSD. The diagnoses of PSD and aphasia were confirmed by a psychiatrist and a speech-language pathologist, respectively. In this open case series, patients (n = 4) received 10 sessions (once a day) of bilateral tDCS to the dorsolateral prefrontal cortex (DLPFC) and two additional sessions after two and four weeks, for a total of 12 sessions. All patients exhibited improvement in depression after tDCS, as indicated by a decrease in SADQ (47.5%) and in ADRS (65.7%). This improvement was maintained four weeks after the treatment. In this preliminary, open-label study conducted in four PSD patients with aphasia, bilateral tDCS over the DLPFC was shown to induce a substantial mood improvement; tDCS was safe and well tolerated by every patient. Stroke patients with aphasia can be safely treated for PSD with tDCS. Sham-controlled studies are necessary to evaluate this technique further.

Objectives Patients with frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) may be agraphic. The study aimed at characterizing agraphia in individuals with a P301L MAPT mutation. Methods Two pairs of siblings with FTDP-17 were longitudinally examined for agraphia in relation to language and cognitive deficits. Results All patients presented with dysexecutive agraphia. In addition, in the first pair of siblings one sibling demonstrated spatial agraphia with less pronounced allographic agraphia and the other sibling had aphasic agraphia. Aphasic agraphia was also present in one sibling from the second pair. Conclusion Agraphia associated with FTDP-17 is very heterogeneous. PMID:23121543

The estimated prevalence of aphasia in the UK and the USA is 250 000 and 1 000 000, respectively. The commonest aetiology is stroke. The impairment may improve with behavioural therapy, and trials using cortical stimulation or pharmacotherapy are undergoing proof-of-principle investigation, but with mixed results. Aphasia is a heterogeneous syndrome, and the simple classifications according to the Broca-Wernicke-Lichtheim model inadequately describe the diverse communication difficulties with which patients may present. Greater knowledge of how intact neural networks promote recovery after aphasic stroke, either spontaneously or in response to interventions, will result in clearer hypotheses about how to improve the treatment of aphasia. Twenty-five years ago, a pioneering study on healthy participants heralded the introduction of functional neuroimaging to the study of mechanisms of recovery from aphasia. Over the ensuing decades, such studies have been interpreted as supporting one of three hypotheses, which are not mutually exclusive. The first two predate the introduction of functional neuroimaging: that recovery is the consequence of the reconstitution of domain-specific language systems in tissue around the lesion (the 'perilesional' hypothesis), or by homotopic cortex in the contralateral hemisphere (the 'laterality-shift' hypothesis). The third is that loss of transcallosal inhibition to contralateral homotopic cortex hinders recovery (the 'disinhibition' hypothesis). These different hypotheses at times give conflicting views about rehabilitative intervention; for example, should one attempt to activate or inhibit a contralateral homotopic region with cortical stimulation techniques to promote recovery? This review proposes that although the functional imaging data are statistically valid in most cases, their interpretation has often favoured one explanation while ignoring plausible alternatives. In our view, this is particularly evident when recovery is

Repetitive phenomena in spontaneous speech were investigated in 30 patients with chronic infarctions of the left hemisphere which included Broca's and/or Wernicke's area and/or the basal ganglia. Perseverations, stereotypies, and echolalias occurred with all types of brain lesions, automatisms and recurring utterances only with those patients, whose infarctions involved Wernicke's area and basal ganglia. These patients also showed more echolalic responses. The results are discussed in view of the role of the basal ganglia as motor program generators.

We report the oral picture naming performance of the German aphasic MW who presented with frequent meaning related word substitutions (e.g. tiger ==> lion) and word finding blockings (omissions) while his phonological capacities at the single word level were nearly preserved. Targets were controlled for their 'semantic competitiveness', that is, whether there exist closely meaning related lexical competitors or not. Semantic errors were far more numerous with the highly competitive targets than with the low competitive ones. However, omissions were more frequent with the low competitive items so that the sum of the semantic errors and of the omissions was comparable in both conditions. This inverse and compensatory relationship suggests that both error types are not mutually independent. The found pattern is at odds with serial psycholinguistic theories which locate word selection (and misselection) and word form access (and blockings) at different and serially connected stages of word production but supports theories which allow for a parallel architecture in lexical activation and selection involving the word form level.

Some extent of ambiguity is ubiquitous in everyday conversations. For example, words have multiple meaning and very common pronouns, like "he" and "she" (anaphoric pronouns), have little meaning on their own and refer to a noun that has been previously introduced in the discourse. Ambiguity triggers a decision process that is not a subroutine of language processing but rather a more general domain resource. Therefore non-aphasic patients with limited decision-making capability can encounter severe limitation in language processing due to extra linguistic limitations. In the present study, we test patients with behavioral variant frontotemporal degeneration (bvFTD), focusing on anaphora as a paradigmatic example of ambiguity resolution in the linguistic domain. bvFTD is characterized by gray matter (GM) atrophy in prefrontal cortex, but relative sparing of peri-Sylvian cortex. A group of patients with parietal disease due to corticobasal syndrome (CBS) was also tested here in order to investigate the specific role of prefrontal cortex in the task employed in the current study. Participants were presented with a pair of sentences in which the first sentence contained two nouns while the second contained a pronoun. In the experimental (ambiguous) condition, both nouns are plausible referents of the pronoun, thus requiring decision-making resources. The results revealed that bvFTD patients are significantly less accurate than healthy seniors in identifying the correct referent of a pronoun in the ambiguous condition, although CBS patients were as accurate as healthy seniors. Imaging analyses related bvFTD patients' performance to GM atrophy in ventromedial prefrontal cortex (vmPFC). These results suggest that bvFTD patients have difficulties in decision processes that involve the resolution of an ambiguity.

Selective deficits in aphasics patients’ grammatical production and comprehension are often cited as evidence that syntactic processing is modular and localizable in discrete areas of the brain (e.g., Y. Grodzinsky, 2000). The authors review a large body of experimental evidence suggesting that morphosyntactic deficits can be observed in a number of aphasic and neurologically intact populations. They present new data showing that receptive agrammatism is found not only over a range of aphasic groups, but is also observed in neurologically intact individuals processing under stressful conditions. The authors suggest that these data are most compatible with a domain-general account of language, one that emphasizes the interaction of linguistic distributions with the properties of an associative processor working under normal or suboptimal conditions.

The present study examined linguistic plastic reorganization of language through Evoked Potentials in a group of 17 non-fluent aphasic patients who had suffered left perisylvian focal lesions, and showed a good linguistic recovery. Language reorganisation was probed with three linguistic tasks (Phonological, Semantic, Orthographic), the early word recognition potential (N150) and the later phonological-related component (N350). Results showed the typical left-lateralised posterior N150 in healthy controls (source: left Fusiform Gyrus), that was bilateral (Semantic) or right sided (Phonological task) in patients (sources: right Inferior/Middle Temporal and Fusiform Gyri). As regards N350, controls revealed different intra- and inter-hemispheric linguistic activation across linguistic tasks, whereas patients exhibited greater activity in left intact sites, anterior and posterior to the damaged area, in all tasks (sources: Superior Frontal Gyri). A comprehensive neurofunctional model is presented, describing how complete intra- and inter-hemispheric reorganisation of the linguistic networks occurs after aphasic damage in the strategically dominant left perisylvian linguistic centres.

Eight patients with cerebral vascular disease and aphasia were studied just after the stroke. The clinical, neuropsychiatric, EEG and neuro-radiological aspects were evaluated. The patients were submitted to the psychological and phonoaudiological studies. The authors correlated the neurological lesions to the structural alteration of the intelligence, to the praxic and estheognostic alterations and also to the language disturbances. The criterions adopted by the World Health Organization and the genetics classification of Jean Piaget were used for the intellectual level classification. The results suggest that the intelligence evaluated through Leither's non-verbal test is better preserved in some asphasics.

The linguistic structure of specific introductory type clauses, which appear at a relatively high frequency in the utterances of a severely brain damaged fluent aphasic with neologistic jargon speech, is examined. The analysis is restricted to one fifty-six-year-old male patient who suffered massive subdural hematoma. (SCC)

Patients with left hemisphere (LH) or right hemisphere (RH) brain injury due to stroke were tested on a speeded, color discrimination task in which two factors were manipulated: 1) the categorical relationship between the target and the distracters and 2) the visual field in which the target was presented. Similar to controls, the RH patients were faster in detecting targets in the right visual field when the target and distracters had different color names compared to when their names were the same. This effect was absent in the LH patients, consistent with the hypothesis that injury to the left hemisphere handicaps the automatic activation of lexical codes. Moreover, the LH patients showed a reversed effect, such that the advantage of different target-distracter names was now evident for targets in the left visual field. This reversal may suggest a reorganization of the color lexicon in the right hemisphere following left hemisphere brain injury and/or the unmasking of a heightened right hemisphere sensitivity to color categories.

The performance of eight machine learning classifiers were compared with three aphasia related classification problems. The first problem contained naming data of aphasic and non-aphasic speakers tested with the Philadelphia Naming Test. The second problem included the naming data of Alzheimer and vascular disease patients tested with Finnish version of the Boston Naming Test. The third problem included aphasia test data of patients suffering from four different aphasic syndromes tested with the Aachen Aphasia Test. The first two data sets were small. Therefore, the data used in the tests were artificially generated from the original confrontation naming data of 23 and 22 subjects, respectively. The third set contained aphasia test data of 146 aphasic speakers and was used as such in the experiments. With the first and the third data set the classifiers could successfully be used for the task, while the results with the second data set were less encouraging. However, based on the results, no single classifier performed exceptionally well with all data sets, suggesting that the selection of the classifier used for classification of aphasic data should be based on the experiments performed with the data set at hand.

This study presents neuropsychological evidence for differences in the semantic representations underpinning spoken and written word comprehension. Potential modality-based discrepancies in the semantic system were examined by testing whether spoken word (auditory-verbal input) and written word (visual-verbal input) comprehension exhibited the same effect profile on variables typically used to distinguish so-called access and storage disorders (e.g., response consistency, sensitivity to item frequency). The study was based on the premise that damage to a common set of semantic representations should have an equivalent impact upon comprehension performance irrespective of input modality, whereas damage to partially dissociable semantic representations may give rise to different qualities of deficit (access/storage) in the comprehension of stimuli presented in different input modalities (spoken/written). The study involved two patients with global aphasia following left middle cerebral artery stroke (F.B.I. and H.O.P.). The two patients showed matched performance on conventional tests of single word comprehension with clear evidence of semantic impairment for stimuli presented in both the spoken and written input modalities. However, in H.O.P., spoken and written word comprehension was affected in the same way by variations in stimulus category, frequency, and multiple stimulus presentations, whilst in F.B.I., there were clear differences between input modalities with all three variables. More specifically, F.B.I.'s written word comprehension was significantly affected by category (living > nonliving) and frequency (high > low) but not multiple presentations (single = multiple), more consistent with degradation of stored representations (storage deficit). By contrast, his spoken word comprehension was unaffected by category (living = nonliving) and frequency (high = low) but was affected by multiple presentations (single > multiple; serial
This study investigates neighbourhood density effects on lexical decision performance (both accuracy and response times) of aphasic patients. Given earlier results on lexical activation and deactivation in Broca's and Wernicke's aphasia, the prediction was that smaller neighbourhood density effects would be found for Broca's aphasic patients,…

Melodic intonation therapy (MIT) is a treatment program for the rehabilitation of aphasic patients with speech production disorders. We report a case of severe chronic non-fluent aphasia unresponsive to several years of conventional therapy that showed a marked improvement following intensive 9-day training on the Japanese version of MIT (MIT-J). The purpose of this study was to verify the efficacy of MIT-J by functional assessment and examine associated changes in neural processing by functional magnetic resonance imaging. MIT improved language output and auditory comprehension, and decreased the response time for picture naming. Following MIT-J, an area of the right hemisphere was less activated on correct naming trials than compared with before training but similarly activated on incorrect trials. These results suggest that the aphasic symptoms of our patient were improved by increased neural processing efficiency and a concomitant decrease in cognitive load. PMID:27698650

A classic observation in neurology is that aphasics can sing words they cannot pronounce otherwise. To further assess this claim, we investigated the production of sung and spoken utterances in eight brain-damaged patients suffering from a variety of speech disorders as a consequence of a left-hemisphere lesion. In Experiment 1, the patients were…

Phonological theories have raised the notion of a universally preferred syllable type which is defined in terms of its sonority structure (e.g., ). Empirical evidence for this notion has been provided by distributional analyses of natural languages and of language acquisition data, and by aphasic speech error analyses. The present study investigates frequency distributions of syllable types in German, which allows for a rather complex syllable structure, and in neologistic utterances of a German speaking jargon aphasic. The findings suggest that the sonority structure of the patient's neologisms is generally in accordance with the notion of theoretically preferred syllables. Moreover, comparative analyses suggest that the predominance of the preferred syllable type is especially pronounced in the aphasic data. On the basis of these findings, the influence of sonority in impaired phonological lexical processing is discussed.

How do aphasics deal with the rich inflectional marking available in agglutinative languages like Hungarian? For the Hungarian noun alone, aphasics have to deal with over 15 basic case markings and dozens of possible combinations of these basic markings. Using the picture description task of MacWhinney and Bates (1978), this study examined the use of inflectional markings in nine Broca's and five Wernicke's aphasic speakers of Hungarian. The analysis focused on subject, direct object, indirect object, and locative nominal arguments. Compared to normals, both groups had a much higher rate of omission of all argument types. Subject ellipsis was particularly strong, as it is in normal Hungarian. There was a tendency for Broca's to omit the indirect object and for Wernicke's to omit the direct object. Across argument types, Wernicke's had a much higher level of pronoun usage than did Broca's. Broca's also showed a very high level of article omission. Compared to similar data reported by Slobin (this issue) for Turkish, the Hungarian aphasics showed an elevated level of omission of case markings. Addition errors were quite rare, but there were 14 substitutions of one case marking for another. These errors all involved the substitution of some close semantic competitor. There were no errors in the basic rules for vowel harmony or morpheme order. Overall the results paint a picture of a group of individuals whose grammatical abilities are damaged and noisy, but still largely functional. Neither the view of Broca's as agrammatic nor the view of Wernicke's as paragrammatic was strongly supported.

Two fluent aphasics, IG and GL, performed a phonological priming task in which they repeated an auditory prime then named a target picture. The two patients both had selective deficits in word production: they were at or near ceiling on lexical comprehension tasks, but were significantly impaired in picture naming. IG's naming errors included both…

A test of sentence comprehension administered in four input-output modality combinations to a group of aphasic bilinguals and monolingual hispanophones provides evidence that aphasics tend to use pragmatic-mode (in the sense of Givón, 1979, On understanding-grammar, New York, Academic Press) strategies in approaching this task. When five factors were identified and dichotomized with respect to the pragmatic-mode-syntactic-mode dimension, the patients performed significantly better on items classified as pragmatic than on those classified as syntactic, in both languages. The results support a vertical/hierarchical view of aphasic language dissolution.

It is well established that patients with semantic memory impairment show a relative sparing of general superordinate information as compared with more detailed item-specific information. The objective of the current study was to examine whether or not this superordinate superiority effect is also reliably observed in individuals with stroke. The participants were 3 patients with a diagnosis of semantic dementia (SD) and 4 left middle cerebral artery stroke patients. In the first experiment, participants were administered a series of spoken-word-picture matching tasks, in which picture identity was probed under two conditions: item name (e.g., goose, beetle, shark, hedgehog) and superordinate name (e.g., bird, insect, fish, mammal). The SD patients showed the predicted pattern of performance, identifying stimuli significantly more accurately by their superordinate term than by their specific name. By contrast, the stroke patients showed the reverse pattern of inferior performance in the superordinate condition in all versions of the experimental task. In a second experiment comparing comprehension ofbasic-level names (e.g., dog, bird, fish) and subordinate-level names (e.g., Dalmatian, sparrow, trout), stroke patients also showed a reversal of the normal basic-level effect, showing less accurate comprehension of basic-level names. The pattern of results documented among the stroke patients cannot be accommodated obviously or readily by existing models of conceptual knowledge. These contrasting abilities of SD patients, stroke patients, and normal healthy participants to process subordinate, basic-level, and superordinate names are considered in relation to disorders of executive processing and taxonomic categorization.

Aphasic patients often exhibit increased right hemisphere activity during language tasks. This may represent takeover of function by regions homologous to the left-hemisphere language networks, maladaptive interference, or adaptation of alternate compensatory strategies. To distinguish between these accounts, we tested language comprehension in 25 aphasic patients using an online sentence-picture matching paradigm while measuring brain activation with MEG. Linguistic conditions included semantically irreversible (“The boy is eating the apple”) and reversible (“The boy is pushing the girl”) sentences at three levels of syntactic complexity. As expected, patients performed well above chance on irreversible sentences, and at chance on reversible sentences of high complexity. Comprehension of reversible non-complex sentences ranged from nearly perfect to chance, and was highly correlated with offline measures of language comprehension. Lesion analysis revealed that comprehension deficits for reversible sentences were predicted by damage to the left temporal lobe. Although aphasic patients activated homologous areas in the right temporal lobe, such activation was not correlated with comprehension performance. Rather, patients with better comprehension exhibited increased activity in dorsal fronto-parietal regions. Correlations between performance and dorsal network activity occurred bilaterally during perception of sentences, and in the right hemisphere during a post-sentence memory delay. These results suggest that effortful reprocessing of perceived sentences in short-term memory can support improved comprehension in aphasia, and that strategic recruitment of alternative networks, rather than homologous takeover, may account for some findings of right hemisphere language activation in aphasia.

The methods of the Italian physician Maria Montessori influenced the development of modern learning practices. There is general agreement that the Montessori phenomenon is personality forming. Aspects of this method, which are relevant for the rehabilitation of the brain-damaged and, in particular, the aphasics are presented. Possible shifts of emphasis within the relationship therapist - method - patient are analysed. Examples are used to outline in how far an increasingly patient-oriented therapy can influence the development of the aphasic patient.

Ictal-MRI studies including diffusion-weighted imaging (DWI), perfusion-weighted imaging (PWI), and MR-angiography (MRA) in patients with aphasic status epilepticus (ASE) are lacking. In this report, we aim to describe the consequences of the ASE on DWIs and its impact on cerebral circulation. We retrospectively studied eight patients with ASE confirmed by ictal-EEG, who underwent ictal-MRI shortly after well-documented onset (mean time delay 3 h). ASE consisted in fluctuating aphasia, mostly associated with other subtle contralateral neurological signs such as hemiparesia, hemianopia, or slight clonic jerks. In MRI, six patients showed cortical temporoparietal hyperintensity in DWI and four of them had also ipsilateral pulvinar lesions. Five patients showed close spatial hyperperfusion areas matching the DWI lesions and an enhanced blow flow in the middle cerebral artery. Parenchymal lesions and hemodynamic abnormalities were not associated with seizure duration or severity in any case. The resolution of DWI lesions at follow-up MRI depended on the length of the MRIs interval. In patients with ASE, lesions on DWI in the temporo-parietal cortex and pulvinar nucleus combined with local hyperperfusion can be observed, even when they appear distant from the epileptic focus or the language areas.

Research has demonstrated that the presentation of auditory and visual cues is an effective clinical procedure for improving picture naming of nonfluent aphasic speakers. The effect of combined cue presentation, however, has not been clearly demonstrated. The present study investigated the effect of single and multiple cueing techniques used with nonfluent (Broca's) aphasic patients. The subjects were divided into a minimum or maximum error group based on their performance on a picture-naming task. Printed words (in either cursive or manuscript style), initial syllables, and sentence completion cues were presented independently and in combination. Discussion is directed toward the potential clinical application of multiple cueing techniques.

Background. Stroke survivors with aphasia experience difficulty associated with their communication disorder. While much has been written about aphasia's impacts on partners/family, we lack data regarding the psychosocial adjustment of aphasic stroke survivors, with a paucity of data from the patients themselves. Methods. Qualitative study of lived experiences of individuals with poststroke aphasia. Each of the stroke survivors with aphasia completed 3-4 semistructured interviews. In most cases, patients' partners jointly participated in interviews, which were transcribed and analyzed using techniques derived from grounded theory. Results. 12 patients were interviewed, with the total of 45 interviews over 18 months. Themes included poststroke changes in patients' relationships and identities, which were altered across several domains including occupational identity, relationship and family roles, and social identity. While all these domains were impacted by aphasia, the impact varied over time. Conclusion. Despite the challenges of interviewing individuals with aphasia, we explored aphasia's impacts on how individuals experience their identity and develop new identities months and years after stroke. This data has important implications for primary care of patients with aphasia, including the importance of the long-term primary care relationship in supporting psychosocial adjustment to life after aphasic stroke.

Within a discrete two-stage model of lexicalization, semantic errors and errors of omission are assumed to be independent events. In contrast, cascading and interactive models allow for an influence of word form on lexical selection and thus for an inherent relationship in accounting for both error types. A group of 17 aphasic patients was…

The study investigated A. R. Luria's hypothesis that aphasic subgroups (Broca's, conduction, Wernicke's, and anomic aphasics) would respond differentially to phonemic prompts. Results, with the exception of the anomic aphasic group, supported Luria's predictions. (Author/DB)
This article gives a brief introduction to the content of aphasic discourse analysis, the theoretical frameworks applied, and critical findings . It also points out the problem that faces the study, the variety of study methods that arises, and the future trend. The structuralists tend to focus on the micro aspects of the discourse while the functionalists on its general structure and the meaning. The study in the future shall address the connection of these two levels.

We describe an HIV-infected, bilingual patient presenting with Wernicke's aphasia due to partial status epilepticus with periodic lateralized epileptiform discharges, as the first sign of AIDS-toxoplasmosis complex. The localization of the native and secondary language centers in the brain and the possible role of recurrent seizures in the fluctuating course of Wernicke's aphasia in this patient are discussed. The clinical course of this patient supports the belief that a second language area for a second language learned in the later stages of life is located in an area different from that for the native language but still in close proximity to it.

With prevalence of 10–20% in adults in developed countries, gallstone disease (GSD) is one of the most prevalent and costly gastrointestinal tract disorders in the world. In addition to gallstone disease, chronic liver disease (CLD) is also an important global public health problem. The reported frequency of gallstone in chronic liver disease tends to be higher. The prevalence of gallstone disease might be related to age, gender, etiology, and severity of liver disease in patients with chronic liver disease. In this review, the aim was to identify the epidemiology, mechanisms, and treatment strategies of gallstone disease in chronic liver disease patients. PMID:28251162

The specialty of oral and maxillofacial surgery has had at its core the foundations of anesthesia and pain and anxiety control. This article attempts to refamiliarize the reader with clinical pearls helpful in the management of patients with chronic pain conditions. The authors also hope to highlight the interplay of chronic pain and psychology as it relates to the oral and maxillofacial surgery patient. To that end, the article outlines and reviews the neurophysiology of pain, the definitions of pain, conditions encountered by the oral and maxillofacial surgeon that produce chronic pain, the psychological impact and comorbidities associated with patients experiencing chronic pain conditions, and concepts of multimodal treatment for patients experiencing chronic pain conditions.

Two advanced magnetic resonance neuroimaging techniques, functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), have recently made their way into clinically oriented research and hold great promise to study the brain's adaptive changes of function and structure after aphasic stroke, respectively. Such functional and structural neuroplasticity is thought to underlie the recovery of language function, occurring spontaneously and/or in the context of therapeutic intervention. With fMRI, brain activity can be visualized. Spontaneous brain activity, present in multiple brain networks, is measured with resting-state fMRI and language-related brain activity by having the subject perform a language task during scanning (task-based fMRI). With DTI the major white matter tracts, such as the dorsal and ventral language pathways and the commissural fibers, can be visualized and quantified. Both techniques are entirely noninvasive and thus offer the unique opportunity to perform multiple assessments within the same subject. To gain more insight in functional and structural neuroplasticity after aphasic stroke, advanced magnetic resonance neuroimaging studies in specific patient populations, at several stages after stroke and in the course of language recovery, are needed. Such studies will help to clarify the influence of the many factors that play a role in the recovery of language function and are thus vital to further the development of aphasia therapy. Application of these techniques in aphasic stroke patients, however, is not without challenge. The purpose of this article is to discuss the methodologic challenges of fMRI and DTI in the assessment of language recovery after aphasic stroke.

Background Concomitant use of opioids and promethazine has been reported in various subpopulations, including methadone maintenance patients, injection drug users, and at-risk teenagers. Promethazine is thought to potentiate the “high” from opioids. However, to date, the prevalence of promethazine use has not been determined among patients prescribed opioids for chronic pain. Methods Urine samples from 921 patients prescribed opioids for chronic pain were analyzed for promethazine. Demographic data, toxicology results, and opioid prescription information were obtained through medical record abstraction. We assessed the prevalence and factors associated with promethazine use with bivariable and multivariable statistics. Results The prevalence of promethazine-positive urine samples among chronic pain patients was 9%. Only 50% of promethazine-positive patients had an active prescription for promethazine. Having benzodiazepine-positive urine with no prescription for a benzodiazepine was statistically associated with promethazine use. Also, having a prescription for methadone for pain or being in methadone maintenance for the treatment of opioid dependence were both statistically associated with promethazine use. Chronic pain patients prescribed only a long-acting opioid were more likely to have promethazine-positive urines than patients prescribed a short-acting opioid. Conclusions The study provides compelling evidence of significant promethazine use in chronic pain patients. Promethazine should be considered as a potential drug of abuse that could cause increased morbidity in opioid-using populations. PMID:25754939

The aim of this study was to identify resilience profiles of patients with chronic pain. Using latent class analysis in a sample of 414 patients with chronic musculoskeletal pain, three profiles were identified: primary resilience (40%), consisting of individuals 40 years or younger with high education, who seek medical care, are not working, and without symptoms of psychological stress; secondary resilience (30%), consisting of women over 54 years of age with low schooling, who seek medical care, are not working, and with low likelihood of symptoms of psychological stress; tertiary resilience (29%), women with medium schooling, 40 to 54 years old, working, who do not seek medical care, and with a high likelihood of symptoms of psychological stress. The three profiles display different paths of resilience in chronic pain that are relevant to clinical practice, highlighting the importance of multidisciplinary care for patients with chronic pain.

An increased risk of thromboembolic events among patients with chronic immune thrombocytopenia has been reported but is still not fully understood. A thrombophilia panel (factors suspected/known to denote a thrombophilic state or indicate activation of the clotting cascade) was measured in previously treated patients with chronic immune thrombocytopenia enrolled in an eltrombopag trial to assess potential thrombophilia risk markers. Of 167 patients, 136 (81%) had abnormal levels of at least 1 known or suspected thrombosis risk marker or coagulation cascade activation marker. Six patients reported thromboembolic events, and all of these patients had at least two abnormal analytes in the thrombophilia panel. The presence of multiple baseline thrombophilia risk markers support the theory that chronic immune thrombocytopenia is a pro-thrombotic disease.

Patients with chronic heart failure (HF) are limited in their quality of life, have a poor prognosis and face frequent hospitalisations. Patient self-management was shown to improve quality of life, reduce rehospitalisations and costs in patients with chronic HF. Comprehensive disease management programmes are critical to foster patient self-management. The chronic care model developed by the WHO serves as the basis of such programmes. In order to develop self-management skills a needs orientated training concept is mandatory, as patients need both knowledge of the illness and the ability to use the information to make appropriate decisions according to their individual situation. Switzerland has no established system for the care of patients with chronic diseases in particular those with HF. For this reason a group of Swiss experts for HF designed a model for disease management for HF patients in Switzerland. Since 2009 the Swiss Heart Foundation offers an education programme based on this model. The aim of this programme is to offer education and support for practitioners, patients and families. An initial pilot evaluation of the program showed mixed acceptance by practitioners, whereas patient assessed the program as supportive and in line with their requirements.

The chemoluminescence test in 49 patients with lingering inflammatory chronic bronchitis has revealed inhibition of generation of active oxygen forms in the whole blood, intensification of lipid peroxidation in the serum, depression of local immunity. Administration of halotherapy to the above patients results in correction of disturbances of free-radical oxidation, improves local immunity and clinical course of the disease.

While evidence suggests that transcranial direct current stimulation (tDCS) may facilitate language recovery in chronic post-stroke aphasia, individual variability in patient response to different patterns of stimulation remains largely unexplored. We sought to characterize this variability among chronic aphasic individuals, and to explore whether repeated stimulation with an individualized optimal montage could lead to persistent reduction of aphasia severity. In a two-phase study, we first stimulated patients with four active montages (left hemispheric anode or cathode; right hemispheric anode or cathode) and one sham montage (Phase 1). We examined changes in picture naming ability to address (1) variability in response to different montages among our patients, and (2) whether individual patients responded optimally to at least one montage. During Phase 2, subjects who responded in Phase 1 were randomized to receive either real-tDCS or to receive sham stimulation (10 days); patients who were randomized to receive sham stimulation first were then crossed over to receive real-tDCS (10 days). In both phases, 2 mA tDCS was administered for 20 min per real-tDCS sessions and patients performed a picture naming task during stimulation. Patients' language ability was re-tested after 2-weeks and 2-months following real and sham tDCS in Phase 2. In Phase 1, despite considerable individual variability, the greatest average improvement was observed after left-cathodal stimulation. Seven out of 12 subjects responded optimally to at least one montage as demonstrated by transient improvement in picture-naming. In Phase 2, aphasia severity improved at 2-weeks and 2-months following real-tDCS but not sham. Despite individual variability with respect to optimal tDCS approach, certain montages result in consistent transient improvement in persons with chronic post-stroke aphasia. This preliminary study supports the notion that individualized tDCS treatment may enhance aphasia

A 68-year-old man, immunocompromised due to non-Hodgkin lymphoma and chemotherapy, was admitted for a community-acquired norovirus infection. He developed chronic intermittent diarrhoea and cachexia. A video-capsule examination showed severe mucosal atrophy in the jejunum. The patient died eight months after the initial norovirus infection. Eight of the nine stool examinations were positive for the norovirus during this entire period. Excretion of norovirus is known to persist after the symptoms have been resolved. However, there is only one previously reported case of excretion over such a long period. Recognising a chronic norovirus infection in immunocompromised patients is vital as then complications such as mucosal atrophy with malabsorption and cachexia can be diagnosed and supportive therapy can be started. Furthermore, recognising a chronic norovirus infection is essential for preventing norovirus outbreaks. Infected patients should always be isolated, regardless of their symptoms and faecal viral load.

A case of a Spanish-speaking aphasic patient who produced a great number of semantic paralexias in reading aloud and who showed other symptoms consistent with the diagnosis of deep dyslexia is presented. In this study, (a) the production of semantic paralexias and the features of the deep dyslexia syndrome which have only recently begun to be studied in Spanish-speaking patients, are analyzed; and (b) the "obligatory character of phonological mediation in the reading of Spanish proposed by some authors is discussed.

Bilingualism has been found to delay onset of dementia and this has been attributed to an advantage in executive control in bilinguals. However, the relationship between bilingualism and cognition is complex, with costs as well as benefits to language functions. To further explore the cognitive consequences of bilingualism, the study used Frontotemporal dementia (FTD) syndromes, to examine whether bilingualism modifies the age at onset of behavioral and language variants of Frontotemporal dementia (FTD) differently. Case records of 193 patients presenting with FTD (121 of them bilingual) were examined and the age at onset of the first symptoms were compared between monolinguals and bilinguals. A significant effect of bilingualism delaying the age at onset of dementia was found in behavioral variant FTD (5.7 years) but not in progressive nonfluent aphasia (0.7 years), semantic dementia (0.5 years), corticobasal syndrome (0.4 years), progressive supranuclear palsy (4.3 years) and FTD-motor neuron disease (3 years). On dividing all patients predominantly behavioral and predominantly aphasic groups, age at onset in the bilingual behavioral group (62.6) was over 6 years higher than in the monolingual patients (56.5, p=0.006), while there was no difference in the aphasic FTD group (60.9 vs. 60.6 years, p=0.851). The bilingual effect on age of bvFTD onset was shown independently of other potential confounding factors such as education, gender, occupation, and urban vs rural dwelling of subjects. To conclude, bilingualism delays the age at onset in the behavioral but not in the aphasic variants of FTD. The results are in line with similar findings based on research in stroke and with the current views of the interaction between bilingualism and cognition, pointing to advantages in executive functions and disadvantages in lexical tasks.

Aphasia, defined as an acquired impairment of linguistic abilities, can be accompanied by a diversity of neuropsychological dysfunction. Accordingly, the necessity to include cognitive testing in the diagnosis of aphasia is increasingly recognized. Here we present the Aphasia Check List (ACL), a new test battery for the assessment of aphasic and associated cognitive disorders. The language part of the battery provides a differentiated profile of important linguistic abilities. In addition, the ACL includes nonverbal screening tests for three neuropsychological domains: memory, attention, and reasoning. Dysfunctions in these domains have been observed in aphasic patients and can have an impact on language function. The ACL is applicable to patients with language disturbances of different etiologies, different stages of disease, and to patients with mild to severe aphasia. As the entire test duration is only about 30 minutes, the ACL is also economically valuable. It thus presents an adequate starting point in aphasia diagnosis for a wide range of patients. Here we describe the construction of the ACL, and the normative study of its original German version with 154 aphasic patients and 106 healthy comparison subjects. The ACL cognition part revealed additional neuropsychological dysfunction in the aphasia group. We present the patterns of these dysfunctions and their correlations with language deficits.

There is an ongoing debate as to whether singing helps left-hemispheric stroke patients recover from non-fluent aphasia through stimulation of the right hemisphere. According to recent work, it may not be singing itself that aids speech production in non-fluent aphasic patients, but rhythm and lyric type. However, the long-term effects of melody and rhythm on speech recovery are largely unknown. In the current experiment, we tested 15 patients with chronic non-fluent aphasia who underwent either singing therapy, rhythmic therapy, or standard speech therapy. The experiment controlled for phonatory quality, vocal frequency variability, pitch accuracy, syllable duration, phonetic complexity and other influences, such as the acoustic setting and learning effects induced by the testing itself. The results provide the first evidence that singing and rhythmic speech may be similarly effective in the treatment of non-fluent aphasia. This finding may challenge the view that singing causes a transfer of language function from the left to the right hemisphere. Instead, both singing and rhythmic therapy patients made good progress in the production of common, formulaic phrases—known to be supported by right corticostriatal brain areas. This progress occurred at an early stage of both therapies and was stable over time. Conversely, patients receiving standard therapy made less progress in the production of formulaic phrases. They did, however, improve their production of non-formulaic speech, in contrast to singing and rhythmic therapy patients, who did not. In light of these results, it may be worth considering the combined use of standard therapy and the training of formulaic phrases, whether sung or rhythmically spoken. Standard therapy may engage, in particular, left perilesional brain regions, while training of formulaic phrases may open new ways of tapping into right-hemisphere language resources—even without singing.

Psoriasis is a chronic inflammatory disease of multifactorial etiology influenced by genetic, immunological, and environmental factors. We report the case of a patient with psoriasis for more than 25 years who developed hyperuricemia and chronic tophaceous gout with unusual appearance. In psoriasis, hyperuricemia may occur by increased epidermal cell turnover, which accelerates purine metabolism and has uric acid as the product of its catabolism. The association of psoriasis with hyperuricemia can trigger the onset of gouty arthritis, and pose a greater risk of developing other inflammatory comorbidities. Therefore, it is important to periodically investigate uric acid levels in order to treat changes triggered by hyperuricemia. PMID:28225966

Treatment of patients with chronic diseases will be one of the main challenges of medicine in the future. This paper presents an overview of different origins, mechanism, and symptoms necessary for understanding new and different interventions that include a psychosomatic view. In a psychosomatic therapeutic intervention there are very different targets, such as psychological symptoms, personality traits, attitudes toward disease and life, risk behaviour, and social isolation and as biological targets the change of autonomic imbalance and of the effects of the psycho-endocrinological or psycho-immunological stress responses. And there are also different psychosomatic measures that influence the individual biological, psychological and sociological targets. There is a need to give different answer to different questions in the field of psychosomatic and behavioral medicine. Comparative effectiveness research is an important strategy for solving some methodological issues. What is the target of treatment for different diseases: Symptom reduction, healing, or limiting progression to the worst case - the death of patients. We know that, the patient-physician relationship is important for every medical/therapeutic action for patients with chronic diseases. This volume of BioPsychoSocial Medicine will present four different psychosomatic treatment studies from the clinical field in the sense of phase 2 studies: Reports of patients with obesity, anorexia nervosa, chronic somatoform pain and coronary artery disease were presented PMID:22293471

The management of chronic patients is a complex process, which requires the cooperation of all primary care professionals and their interaction with specialists, laboratories and personnel of different organizations. In this paper we show how a Careflow Management System (CfMS) may represent an essential component of an innovative Health Information System (HIS) able to handle the information and communication needs underlying chronic diseases management. On the basis of a general architecture designed for chronic diseases, we describe a CfMS implementation in the area of diabetes management; such a system embeds EPR and telemedicine functionalities as end-users applications as well as a module for inter-organizational communication based on contracts and on XML messages.

Chronic hemodialysis (HD) patients are predisposed to several complications associated with pleural effusion. In addition, uremia can directly cause pleuritis. However, there are inadequate data about pathogenesis and natural course of uremic pleuritis. In this study, 76 chronic HD patients with pleural effusion admitted to the Respiratory Center of Masih Daneshvari Hospital, in Tehran, Iran between June 2005 and May 2011 were evaluated to figure out the etiology of their pleural disease. Among these patients, patients with uremic pleuritis were identified and studied. The rate of uremic pleuritis was 23.7%. Other frequent etiologies of pleural effusion were parapneumonic effusion (23.7%), cardiac failure (19.7%), tuberculosis (6.6%), volume overload, malignancy, and unknown. In patients with uremic pleuritis, dyspnea was the most common symptom, followed by cough, weight loss, anorexia, chest pain, and fever. Compared to patients with parapneumonic effusion, patients with uremic effusion had a significantly higher rate of dyspnea and lower rate of cough and fever. Pleural fluid analysis showed that these patients had a significantly lower pleural to serum lactic dehydrogenase ratio, total pleural leukocytes, and polymorphonuclear count compared to patients with parapneumonic effusion. Improvement was achieved in 94.1% of patients with uremic pleuritis by continuation of HD, chest tube insertion or pleural decortication; an outcome better than the previous reports. Despite the association with an exudative effusion, inflammatory pleural reactions in patients with uremic pleuritis may not be as severe as infection-induced effusions. Owing to the advancement in HD technology and other interventions, outcome of uremic pleuritis may be improved.

This paper uses a discussion of experiments with aphasics' use of verbally derived nouns to illustrate how one linguistic model may be superior to another in accounting for the facts of verbal behavior. The models involved are the transformational, which relates derived nominals to their source verb and lists only the verb in the lexicon, and the…

Phonological theories have raised the notion of a universally preferred syllable type which is defined in terms of its sonority structure (e.g., Clements, 1990). Empirical evidence for this notion has been provided by distributional analyses of natural languages and of language acquisition data, and by aphasic speech error analyses. The present…

We studied the role of urethrovesical reflux in the onset and maintenance of chronic inflammation in the urinary bladder in patients suffering from chronic cystitis combined with pseudopolyposis of the neck of the bladder and proximal part of the urethra. We modelled a simplified version of an urination fragment of a special computer graphic station. The original computer model theoretically proves the existance of urethrovesical reflux caused by pseudopolyposis in the zone of the urinary bladder cervix and/or proximal urethra. The data were confirmed by radionuclide investigation. Our studies proved the presence of urethrovesical reflux in patients with pseudopolyposis of the bladder cervix provoking retrograde infection of the lower urinary tract. We think it necessary to combine conventional conservative treatment of cystitis with endourethral surgical interventions aimed at reestablishment of normal urination.
The nature of research on speech communication in asymmetrical interactions, such as those between a speech therapist and patient, is discussed and some general approaches to therapy are noted. The situation of the aphasic is then considered, in which intervention is particularly difficult due to the lack of some important aspects of interpersonal…

Coronary artery disease, hypertension, congestive heart failure, type 2 diabetes mellitus, osteoarthritis, osteoporosis, and cognitive disorders become more prevalent as people age. Besides delaying the onset of many of these conditions, regular exercise may improve function and delay disability and morbidity in those who have them. Further, exercise may work synergistically with medication to combat the effects of some chronic diseases. Special adaptations for older patients include lower-intensity exercise (eg, fewer repetitions), low-impact exercise (cycling, exercise while sitting), and modified equipment (smaller weights, special shoes, loose clothing). Unresolved issues include development of optimal strategies for motivating older patients to begin and maintain exercise programs.

In a study of the postdischarge treatment of 119 comparable chronic schizophrenics hospitalized and treated after release in six community mental health care systems, it was found that lower rehospitalization rates and longer community survivorship correlated significantly with patients' compliance in early postdischarge treatment plans and the frequency of aftercare visits prescribed for them during the early postrelease period. Rehospitalization rates and community survivorship experience were substantially better for patients of two of the six systems, without disproportionate reduction of their clinical or social functioning in the community. Characteristics of the community care systems with better outcomes are described. PMID:6694221

Chronic kidney disease (CKD) is widely prevalent worldwide, with a special impact on elderly population. Around half of people aged over 75 meet diagnostic criteria for CKD according to the recent 'Kidney disease improving global outcomes' (KDIGO) 2012 clinical practice guideline on the evaluation and management of CKD. However, geriatric patients have characteristics that may not be addressed by general guidelines. Therefore, it is important to know the natural history of the disease, symptoms, and 'red-flags' that could help in the management of these patients. In this review, a complete approach is presented on the pathophysiology, diagnosis, and treatment of CKD in the geriatric population.

Common indications for chronic anticoagulation include mechanical prosthetic heart valve, non-rheumatic atrial fibrillation, and venous thromboembolism. Perioperative management of the chronically anticoagulated patient is a complex medical problem, and includes the following issues: urgency of surgery, risk of thromboembolism in the absence of anticoagulation, bleeding risk, consequences of bleeding, ability to control bleeding physically, and duration of bleeding risk after the procedure. Most patients can be managed safely by stopping oral anticoagulants 4-5 days before surgery and restarting anticoagulation after the procedure at the patient's usual daily dose. In general, dental procedures and cataract extraction can be performed without interrupting anticoagulation. Most other procedures can be safely performed with an INR < or = 1.4. For patients with double-wing prosthetic valves (e.g., St. Jude, Carbomedics) in the aortic position, uncomplicated atrial fibrillation, or a remote (>3 months) history of venous thromboembolism, oral anticoagulants can be stopped 4-5 days before surgery and restarted at the usual daily dose immediately after surgery. For other patients at higher risk of thrombosis, "bridging therapy" with outpatient low molecular weight heparin is safe and effective. For urgent procedures, a small dose of oral vitamin K usually will reduce the INR within 24-36 hours to a level sufficient for surgery and avoids exposure to transfused blood products.

There was investigated a hepatic bile in 50 persons, aged 35-58 years old, including 20--practically healthy persons (I group), 20 patients, suffering chronic fibrose-degenerative pancreatitis (CHFDP) without jaundice syndrome (II group) and 10 patients, suffering CHFDP with jaundice syndrome (III group). There were determined the contents of the bile acids, the lipids and electrolytic contents of bile. A trustworthy difference in the bile contents was registered in patients, suffering CHFDP with the jaundice syndrome and without it, comparing with such in healthy persons. This have had permitted to add the complex of medicinal preoperative preparation of these patients substantially, and to apply the electrolytes content of a bile to apply as an additional diagnostic marker.

15 Broca's aphasics and 14 Wernicke's aphasics, both German and Dutch speaking patients, were presented with a sentence-picture matching task. Both syntactic and semantic distractor pictures were used. Sentences were either reversible or non-reversible, had a topicalized or a non-topicalized word order and contained either of three types of prepositions that were labelled 'syntactic' (case-marking), 'obligatory' (subcategorized) and 'lexical' (locative). Results indicated (a) a significant difference between reversible and non reversible sentences for both Broca's and Wernicke's; (b) no significant differences between these two groups in the differences scores reversible minus non-reversible; (c) an above-chance performance on reversible sentences for both groups. To explain the pattern of differences between the various types of sentences, two schemes of interpretation are presented. The first scheme assumes that both Broca's and Wernicke's have lost basic (but different) syntactic abilities and that they can understand reversible sentences by non-syntactic strategies only. The second scheme assumes that there is no such loss, but that the impairment in Broca's and Wernicke's aphasia is such that the more syntactic analysis is required, the more errors are made. Patients are assumed to approach this task by trying to limit their syntactic analysis to the beginning of the sentence.

Castilla-La Mancha Health Service is developing the integration of care levels due to the challenge of an aging population in the region. Aging is associated with chronic diseases and an increasing number of concomitant diseases. This poses a major care challenge care, with more fragile patients and new needs. This also requires a sustainable approach: the concurrence of several chronic diseases affects the cost of care, which is especially acute in times of severe economic crisis. One of the pillars of the strategy for dealing with chronic diseases in our region is care integration, in an effort to adapt the organization to the new needs. The Balanced Scorecard or Integrated Scorecard of the integration process was introduced as it has been designed. The integration of primary and hospital care at an organizational level has already been completed, and the development of integrated care processes has also been performed in order to achieve real integration at care level. To help finance this, a prospective capitation system is gradually being implemented, achieving a convergence of per capita costs in the different health areas integrated. Nurses has a key role in this process, their skills as educators and trainers in self-care, in the role of case managers of patients with particularly complex conditions, and the role of professional liaison to improve the transition between care areas and units.

Xerostomia is the subjective feeling of a dry mouth, which is relatively common in patients on chronic hemodialysis. Xerostomia can be caused by reduced salivary flow secondary to atrophy and fibrosis of the salivary glands, use of certain medications, restriction of fluid intake and old age. In patients undergoing hemodialysis, xerostomia is associated with the following problems: difficulties in chewing, swallowing, tasting and speaking; increased risk of oral disease, including lesions of the mucosa, gingiva and tongue; bacterial and fungal infections, such as candidiasis, dental caries and periodontal disease; interdialytic weight gain resulting from increased fluid intake; and a reduction in quality of life. Unfortunately, no effective treatment exists for xerostomia in patients on chronic hemodialysis. The stimulation of salivary glands by mechanical means (such as chewing gum) or pharmacological agents (such as pilocarpine and angiotensin-converting-enzyme inhibitors, the latter alone or in combination with angiotensin-receptor blockers), as well as saliva substitutes, are all ineffective, or effective only in the short term. Xerostomia remains a frustrating symptom for patients on hemodialysis, and further efforts should be made to find an effective treatment for it in the near future.

Telemedicine is a valuable extension of the ways in which patients with chronic diseases can be contacted. Patients can easily contact their caregivers within the safe environment of the digital waiting room. Telemedicine especially offers an advantage for those forms of care where the visual aspect is important. Care should be taken with respect to its implementation into the disease management process with careful synchronisation between all involved parties, e.g. patient, caregiver, and organisation. The effectiveness of telemedicine and the savings that can be achieved should be properly established in order to justify the funding of a telemedicine project. Rather than focusing on the possible drawbacks of telemedicine, e.g. safety concerns and the user-friendliness of the system, we should highlight the possibilities that information technology offers.

Background. This study investigated the epidemiology of torus palatinus (TP) and torus mandibularis (TM) in hemodialysis patients and analyzed the influences of hyperparathyroidism on the formation of oral tori. Method. During 2013, 119 hemodialysis patients were recruited for dental examinations for this study. Results. The prevalence of oral tori in our sample group was high at 33.6% (40 of 119). The most common location of tori was TP (70.0%), followed by TM (20.0%), and then both TP and TM (10.0%). Of the 40 tori cases, most (67.5%) were <2 cm in size; moreover, the majority (52.5%) were flat in shape. In symmetry, most (70.0%) occurred in the midline, followed by bilateral sides (20.0%). Notably, the levels of intact parathyroid hormone did not differ in patients with or without tori (P = 0.611). Furthermore, patients with tori did not differ from patients without tori in inflammatory variables such as log high-sensitivity C-reactive protein (P = 1.000) or nutritional variables such as albumin (P = 0.247). Finally, there were no differences between patients with and without tori in adequacy of dialysis (P = 0.577). Conclusions. Neither hyperparathyroidism nor inflammation malnutrition syndrome was found to contribute to the formation of oral tori in chronic hemodialysis patients. Further studies are warranted. PMID:25918724

Ghrelin is a peptide hormone that has modulatory effects on the immune system. This study was designed to evaluate plasma ghrelin levels in patients with chronic periodontitis and to investigate if a relationship exists between ghrelin and periodontal parameters, serum cytokines, and bone turnover markers. Thirty-five chronic periodontitis patients (CP) and periodontal healthy individuals (C) were included in this study. Periodontal parameters were recorded. Blood samples were obtained to determine the levels of total and acylated ghrelin, interleukin-1 beta (IL-1β), tumor necrosis factor-alpha (TNF-α), the soluble receptor activator nuclear factor kappaB ligand (sRANKL), alkaline phosphatase (ALP), and osteocalcin (OSC). Plasma levels of total and acylated ghrelin were significantly elevated in the CP group compared with the C group (p < 0.05). The difference was significant only between males in the two groups (groups were compared with respect to gender) (p < 0.05). There was no difference between the groups regarding the levels of serum sRANKL, TNF-α, and ALP. A relative increase in the serum levels of IL-1β and a decrease in the serum levels of OSC of the CP group were observed (p < 0.05). In addition, positive correlations between total ghrelin/ALP and total ghrelin/acylated ghrelin were discovered. We found no direct correlation between ghrelin levels and periodontal parameters. Our results indicate an increase of total and acylated ghrelin levels in patients with chronic periodontitis. Further, studies in larger populations (which could include ghrelin levels in gingival tissue, gingival crevicular fluid, and saliva) are needed in order to confirm the role of ghrelin in periodontal disease.

Some theories of lexical access in production locate the effect of lexical frequency at the retrieval of a word’s phonological characteristics, as opposed to the prior retrieval of a holistic representation of the word from its meaning. Yet there is evidence from both normal and aphasic individuals that frequency may influence both of these retrieval processes. This inconsistency is especially relevant in light of recent attempts to determine the representation of another lexical property, age of acquisition or AoA, whose effect is similar to that of frequency. To further explore the representations of these lexical variables in the word retrieval system, we performed hierarchical, multinomial logistic regression analyses of 50 aphasic patients’ picture-naming responses. While both log frequency and AoA had a significant influence on patient accuracy and led to fewer phonologically related errors and omissions, only log frequency had an effect on semantically related errors. These results provide evidence for a lexical access process sensitive to frequency at all stages, but with AoA having a more limited effect. PMID:18704797

In a double-blind, placebo-controlled study, an attempt was made to evaluate butaclamol in chronic schizophrenic patients using chlorpromazine (CPZ) as the standard comparative drug. With doses up to 50 mg/day, butaclamol was shown to have significant antipsychotic activity comparable to CPZ but with a much higher incidence of extrapyramidal signs. A more reasonable maintenance dose may be in the range of 5 to 20 mg/day. Rebound insomnia was noted again with butaclamol, which warrants further study.

OBJECTIVE To examine the feasibility and efficacy of integrating home health monitoring into a primary care setting. DESIGN A mixed method was used for this pilot study. It included in-depth interviews, focus groups, and surveys. SETTING A semirural family health network in eastern Ontario comprising 8 physicians and 5 nurses caring for approximately 10 000 patients. PARTICIPANTS Purposeful sample of 22 patients chosen from the experimental group of 120 patients 50 years old or older in a larger randomized controlled trial (N = 240). These patients had chronic illnesses and were identified as being at risk based on objective criteria and physician assessment. INTERVENTIONS Between November 2004 and March 2006, 3 nurse practitioners and a pharmacist installed telehomecare units with 1 or more peripheral devices (eg, blood-pressure monitor, weight scale, glucometer) in patients’ homes. The nurse practitioners incorporated individualized instructions for using the unit into each patient’s care plan. Patients used the units every morning for collecting data, entering values into the system either manually or directly through supplied peripherals. The information was transferred to a secure server and was then uploaded to a secure Web-based application that allowed care providers to access and review it from any location with Internet access. The devices were monitored in the office on weekdays by the nurse practitioners. MAIN OUTCOME MEASURES Acceptance and use of the units, patients’ and care providers’ satisfaction with the system, and patients’ demographic and health characteristics. RESULTS All 22 patients, 12 men and 10 women with an average age of 73 years (range 60 to 88 years), agreed to participate. Most were retired, and a few were receiving community services. Common diagnoses included hypertension, diabetes, cardiovascular disease, and chronic obstructive pulmonary disease. All patients had blood pressure monitors installed, 11 had wired weight
Background Chronic musculoskeletal (MS) pain is common in patients with chronic kidney disease (CKD) undergoing haemodialysis. However, epidemiological data for chronic MS pain and factors associated with chronic MS pain in patients with early- or late-stage CKD who are not undergoing dialysis are limited. Method A cross-sectional study to evaluate the prevalence of chronic MS pain and factors associated with chronic MS pain in patients with early- and late-stage CKD who were not undergoing dialysis, was conducted. In addition, the distribution of pain severity among patients with different stages of CKD was evaluated. Results Of the 456 CKD patients studied, 53.3% (n = 243/456) had chronic MS pain. Chronic MS pain was independently and significantly associated with hyperuricemia as co-morbidity, as well as with the calcium × phosphate product levels. In CKD patients with hyperuricemia, chronic MS pain showed a negative, independent significant association with diabetes mellitus as a co-morbidity (odds ratio: 0.413, p = 0.020). However, in the CKD patients without hyperuricemia as a co-morbidity, chronic MS pain showed an independent significant association with the calcium × phosphate product levels (odds ratio: 1.093, p = 0.027). Furthermore, stage-5 CKD patients seemed to experience more severe chronic MS pain than patients with other stages of CKD. Conclusion Chronic MS pain is common in CKD patients. Chronic MS pain was independently and significantly associated with hyperuricemia as co-morbidity, and with the calcium × phosphate product levels in early- and late-stage CKD patients who were not on dialysis.

Introduction Psoriasis is a chronic, inflammatory, T-cell-mediated and hyperproliferative skin disease characterized by erythematous, squamous, sharply circumscribed and infiltrated plaques. The metabolisms of the collagen proteins undergo considerable changes due to the acceleration of their turnovers as a result of increased prolidase activity in psoriasis patients. Aim To determine the level of prolidase activity in psoriasis patients and evaluate its relationship with the oxidative system. Material and methods The serum prolidase enzyme activity, total antioxidant levels and total oxidant levels of 40 psoriasis patients and a control group including 47 healthy individuals were analyzed by using their serum samples, and their oxidative stress indices were calculated. Results The prolidase levels (p < 0.01), total oxidant levels (p < 0.01) and oxidative stress index levels (p < 0.001) of the patient group were higher than the corresponding parameters in the control group. The total antioxidant level was low (p < 0.01). Although a positive correlation was found between the prolidase and total antioxidant levels and the total oxidant level, no correlation was found between prolidase and the oxidative stress index. Conclusions It has been determined that the activity of the prolidase enzyme increases due to the increased collage turnover in psoriasis patients. Increased serum oxidant levels and oxidative stress indices values may play a role in the pathogenesis of psoriasis. PMID:26015776

In numerous studies of symptoms in patients with chronic hepatitis C there has been no systematic assessment of both fatigue and extrahepatic manifestations. Our objective was to assess the prevalence of fatigue in patients with hepatitis C virus (HCV) infection, and to identify associations between fatigue and clinical and biological hepatic and extrahepatic manifestations. We studied 1614 patients. Data were prospectively recorded during the first visit of patients infected with HCV and the prevalence of fatigue and its association with dermatological, rheumatological, neurological and nephrological manifestations; diabetes; arterial hypertension; auto-antibodies, and cryoglobulinaemia were assessed. Then, using multivariate analysis, we identified demographic, biochemical, immunological, virological, and histological factors associated with the presence of fatigue. Fatigue was present in 53% of patients (95% confidence interval 51-56). In 17% of patients (95% confidence interval 15-19) fatigue was severe, impairing activity. Five other extrahepatic manifestations had a prevalence above 10% including, in decreasing order: arthralgia, paresthesia, myalgia, pruritus, and sicca syndrome. In univariate and multivariate analyses, fatigue, in comparison with the absence of fatigue, was associated with female gender, age over 50 years, cirrhosis, depression and purpura. Independent of these associations, fatigue was associated with arthralgia, myalgia, paresthesia, sicca syndrome and pruritus. The prevalence of fibromyalgia (as defined by the association of fatigue with arthralgia or myalgia) was 19% (95% confidence interval 17-21). There was no significant association between fatigue and the following characteristics: viral load or genotype, alcohol consumption, abnormal thyroid function, and type and level of cryoglobulinaemia. Hence, fatigue is the most frequent extrahepatic manifestation in patients infected with HCV. Fatigue is independently associated with female

In March 2008 and June 2009, an ad hoc working group of nephrologists discussed the status of anaemia therapy with erythropoiesis-stimulating agents [ESA] in patients on chronic haemodialysis, the phenomenon of fluctuations of haemoglobinaemia, and the need for individualisation of ESA treatment. The working group put together the following statements: (1) ESAs increase the haemoglobin concentration and adaptations of the ESA dose adjust the response according to a negative-feedback loop. The long lag time between an ESA dose change and its effect on erythropoiesis is cumbersome. The optimal haemoglobin target concentration is different for every haemodialysis patient; the lowest haemoglobin concentration upon which one could consistently demonstrate a positive subjective and objective clinical benefit in chronic dialysis is 11 g/dL, in contrast to the lowest haemoglobin concentration of 10 g/dL recommended in the current EMEA label for ESAs. (2) Intra-individual fluctuation of haemoglobinaemia over time is unavoidable, not only due to the ESA dose/haemoglobin response interaction, but also, and more importantly, due to the occurrence of acute illnesses and exacerbations of co-morbid conditions. Many different methodologies to characterise haemoglobin variability have been described but there is currently no universally applied definition of the phenomenon. (3) An impact of the haemoglobin level and the amplitude of the haemoglobin fluctuations on patient outcome has been observed. Without disclosing any causal relationship, worse outcomes were associated with haemoglobin fluctuations around the lower target level, but later on, more simply linked to the relative time spent below the haemoglobin concentration of 11 g/dL and to the administration of inappropriately high ESA doses in order to achieve the recommended haemoglobin target range. A plausible mechanism might be that acute illnesses blunt the patients' basal ESA sensitivity; this leads to subnormal and

Due to social, economic and cultural changes, there has been a transformation of Health Services around the world. A new figure has emerged from this: the Active Patient, more responsible, with more information and willing to change his life as a chronic patient. In order to respond to this new situation, several countries have established initiatives such as self-reliance programmes for chronic patients. The aim of this article is to underline the Expert Patient Programme Catalonia(®) and to explain its operation and the results obtained up until now. The purpose of this program is to improve the experience of chronic disease by patients, from meetings in which an expert patient provides his knowledge and experiences to a group of patients with the same disease, with the aim of promoting changes in habits and lifestyles that improve the quality of life and the coexistence of the person with his chronic process.

New selective and more potent drugs for the cure of chronic phase chronic myeloid leukemia patients are now available: physicians in some countries must decide the best option, selecting one of the drugs available. What the main prognostic factors are in order to make this selection remains a matter of discussion. Introducing a 'holistic approach' for the first time in chronic myeloid leukemia, as practiced in other diseases, and looking at the patient in a complete picture, considering several variables, such as comorbidities, age, concomitant drugs, lifestyle and patient expectations, may be of help to understand, patient by patient, the best therapeutic strategy.

Transcranial direct-current stimulation (tDCS) has been suggested to improve language function in patients with post-stroke aphasia. Most studies on aphasic patients, however, were conducted with a very limited follow-up period, if any. In this pilot, single-blind study on chronic post-stroke aphasic patients, we aimed to verify whether or not tDCS is able to extend its beneficial effects for a longer period of time (21 weeks after the end of stimulation). Three aphasic patients underwent anodal tDCS (A-tDCS, 20 min, 1.5 mA) and sham stimulation (S-tDCS) over the left frontal (perilesional) region, coupled with a simultaneous naming training (on-line tDCS). Ten consecutive sessions (5 days per week for 2 weeks) were implemented. In the first five sessions, we used a list of 40 figures, while in the subsequent five sessions we utilized a second set of 40 figures differing in word difficulty. At the end of the stimulation period, we found a significant beneficial effect of A-tDCS (as compared to baseline and S-tDCS) in all our subjects, regardless of word difficulty, although with some inter-individual differences. In the follow-up period, the percentage of correct responses persisted significantly better until the 16th week, when an initial decline in naming performance was observed. Up to the 21st week, the number of correct responses, though no longer significant, was still above the baseline level. These results in a small group of aphasic patients suggest a long-term beneficial effect of on-line A-tDCS.

Many studies reveal effects of verb type on verb retrieval, mainly in agrammatic aphasic speakers. In the current study, two factors that might play a role in action naming in anomic aphasic speakers were considered: the conceptual factor instrumentality and the lexical factor name relation to a noun. Instrumental verbs were shown to be better…

Since liver function is changed by chronic liver diseases, chronic liver disease can lead to different hemorheological alterations during the course of the progression. This study aims to compare alterations in whole blood viscosity in patients with chronic liver disease, focusing on the gender effect. Chronic liver diseases were classified into three categories by patient's history, serologic markers, and radiologic findings: nonalcoholic fatty liver disease (NAFLD) (n = 63), chronic viral hepatitis B and C (n = 50), and liver cirrhosis (LC) (n = 35). Whole blood viscosity was measured by automated scanning capillary tube viscometer, while liver stiffness was measured by transient elastography using FibroScan®. Both systolic and diastolic whole blood viscosities were significantly lower in patients with LC than NAFLD and chronic viral hepatitis (P < 0.001) in male patients, but not in female patients. In correlation analysis, there were inverse relationships between both systolic and diastolic whole blood viscosity and liver stiffness (systolic: r = -0.25, diastolic: r = -0.22). Whole blood viscosity was significantly lower in male patients with LC than NAFLD or chronic viral hepatitis. Our data suggest that whole blood viscosity test can become a useful tool for classifying chronic liver disease and determining the prognosis for different types of chronic liver diseases.

Caloric vestibular stimulation (CVS) is commonly used to diagnose brainstem disorder but its therapeutic application is much less established. Based on the finding that CVS increases blood flow to brain structures associated with language and communication, we assessed whether the procedure has potential to relieve symptoms of post-stroke aphasia. Three participants, each presenting with chronic, unilateral lesions to the left hemisphere, were administered daily CVS for four consecutive weeks. Relative to their pre-treatment baseline scores, two of the three participants showed significant improvement on both picture and responsive naming at immediate and 1-week follow-up. One of these participants also showed improved sentence repetition, and another showed improved auditory word discrimination. No adverse reactions were reported. These data provide the first, albeit tentative, evidence that CVS may relieve expressive and receptive symptoms of aphasia. A larger, sham-controlled study is now needed to further assess efficacy.

This article explores the relationship between automatic and involuntary language in the work of Samuel Beckett and late nineteenth-century neurological conceptions of language that emerged from aphasiology. Using the work of John Hughlings Jackson alongside contemporary neuroscientific research, we explore the significance of the lexical and affective symmetries between Beckett's compulsive and profoundly embodied language and aphasic speech automatisms. The interdisciplinary work in this article explores the paradox of how and why Beckett was able to search out a longed-for language of feeling that might disarticulate the classical bond between the language, intention, rationality and the human, in forms of expression that seem automatic and "readymade".

Four patients developed miliary tuberculosis while undergoing chronic hemodialysis. Two patients had diabetes mellitus. Three of the four patients were hemodialyzed 18--24 months prior to the onset of symptoms. Signs and symptoms included prolonged fever, pleural effusion, pericarditis with pericardial effusion, abdominal pain, weight loss, and ascites. All patients were PPD negative and without historical or radiographic evidence of latent tuberculosis. Disseminated tuberculosis was proven at autopsy in three patients. M. tuberculosis was eventually recovered from pleural fluid and urine in the fourth patient. The immune deficiencies of chronic renal failure and diabetes mellitus are suspected predisposing factors to the development of miliary tuberculosis in these patients.

Background: The aim of our study was to assess the efficacy of Cerebrolysin administration in Broca's aphasics with acute ischemic stroke. Methods: We registered 2,212 consecutive Broca's aphasics following an acute ischemic stroke admitted in four departments of neurology in Romania, between September 2005 and September 2009. Language was evaluated with the Romanian version of the Western Aphasia Battery (WAB). The following inclusion criteria were used for this study: age 20%75 years, admission in the hospital within 12 hours from the onset of the symptoms, diagnosis of first acute left middle cerebral artery (MCA) ischemic stroke, presence of large artery disease (LAD) stroke, a NIHSS score of 5%22 points, and a therapeutic time window within 72 h. Fifty two patients were treated with Cerebrolysin (Cerebrolysin group) as an adjunctive treatment. A placebo group, which received saline infusions (n=104 patients) were matched to the NIHSS and WAB scores, gender and age of the Cerebrolysin group at baseline. We assessed spontaneous speech (SS), comprehension (C), repetition (R), naming (N), and Aphasia Quotient (AQ) scores of the two groups in an open label design, over 90 days, the mRS scores and mortality. Results: The Cerebrolysin and the placebo groups had similar age (66+/%8 versus 65+/%8 years) and sex ratio (14/38 versus 30/74). The mean AQ scores and the mean subscores for 3 subtests of WAB (SS, R, N) were similar at baseline and improved in the Cerebrolysin group significantly (p<0.05) over placebo group at all study time points. The mRS score at 90 days was also lower in the Cerebrolysin group than in the placebo group. Cerebrolysin and placebo were both tolerated and safe, and no difference in the mortality rate was seen (3.8% in each group). Conclusion: Cerebrolysin is effective for the treatment of Broca's aphasics with a first acute ischemic stroke of the left MCA territory. PMID:20945821

OBJECTIVE: To determine the impact of periodontal treatment on serum levels of prohepcidin (the prohormone of hepcidin) and systemic inflammation markers, as well as correlations among these markers, in patients with chronic periodontitis and chronic kidney disease who were not undergoing dialysis. METHODS: We included 56 chronic periodontitis patients, 36 with chronic kidney disease and 20 without systemic diseases and with normal renal function (control group). Chronic kidney disease was defined as suggested by the clinical practice guidelines in the National Kidney Foundation. Chronic periodontitis was defined through clinical attachment level and by probing pocket depth, according to the American Association of Periodontology. The inflammatory markers ultrasensitive C-reactive protein, interleukin-6, and prohepcidin were evaluated before and 3 months after periodontal treatment. RESULTS: The efficacy of periodontal treatment was confirmed by the improvement in clinical parameters of chronic periodontitis in the control and chronic kidney disease groups. Periodontal treatment resulted in significant reductions in ultrasensitive C-reactive protein, interleukin-6 and serum prohepcidin levels in both groups. Moreover, in multivariate linear regression, the reduction in prohepcidin after periodontal treatment was significantly and independently associated with interleukin-6 levels in the control group. CONCLUSIONS: By inducing a decline in the systemic inflammatory response and a decrease in serum prohepcidin, successful periodontal treatment may represent an important means of ameliorating the inflammatory burden seen in patients with chronic kidney disease.

Chronic granulomatous disease is a primary immunodeficiency caused by impaired neutrophil production of reactive oxygen species. Non-infectious colitis is common in chronic granulomatous disease, and high levels of antimicrobial antibodies that are associated with Crohn's disease are common even without colitis. Fecal calprotectin concentration is a marker for intestinal inflammation. We sought to determine whether subclinical intestinal inflammation occurs in asymptomatic chronic granulomatous disease patients. Asymptomatic chronic granulomatous disease patients without overt gastrointestinal symptoms suggestive of colitis at the time of enrollment were studied for fecal calprotectin concentration, antibodies associated with Crohn's disease and systemic inflammatory markers. Eight patients were included, aged 54-176 months. In 7/8 (87.5 %) fecal calprotectin concentration was normal (<50) and elevated (137 mg/kg) in only one patient. This patient later developed colitis. In 7/8 (87.5 %) anti-Saccharomyces cerevisiae antibody was positive. C-reactive protein, albumin, complete blood count and p-anti-neutrophil cytoplasmic antibody were normal in all 8 patients. Subclinical colitis is not evident in most asymptomatic chronic granulomatous disease patients; however, in some patients, fecal calprotectin concentration may be elevated, possibly indicating the presence of subclinical colitis and predicting the occurrence of clinically relevant colitis. Serum anti-Saccharomyces cerevisiae antibody concentrations do not seem to correlate with fecal calprotectin concentration in asymptomatic chronic granulomatous disease patients.

Chronic postoperative pain may lead to physical disability and psychosocial distress. In this longitudinal observational study, for the first time we evaluated the relative frequency of chronic postoperative pain in patients operated for chronic otitis media (COM) at two university hospitals. Patients were questioned about pain at the site of the surgical incision 3-6 months after the operation, and again 3 months after the first visit. Pain intensity was quantified by visual analogue scale (VAS). T test, Chi-square test, and logistic regression were used for analyzing data and multivariate analysis. In 155 patients (42 male, 113 female, mean age: 38.57 ± 10.66 years), chronic postoperative pain was observed in 50 cases (32.3 %). A significant decrease in the average score of VAS was observed from 5.18 to 2.64 within 3 months (P = 0.0001). Statistically significant correlation was observed between chronic postoperative pain and age, sex, acute postoperative pain and history of Irritable Bowel Syndrome or migraine, but after multivariate analysis, only the age group and severe acute post-operation pain were effective on incidence of chronic post-operative pain. In conclusion, surgery for COM is followed by chronic pain in about 32 % of patients, and some risk factors for the development of chronic postoperative pain after this surgery exist, including age and severe acute post-operation pain.

Abstract We explored the use of virtual reality distraction techniques for use as adjunctive therapy to treat chronic pain. Virtual environments were specifically created to provide pleasant and engaging experiences where patients navigated on their own through rich and varied simulated worlds. Real-time physiological monitoring was used as a guide to determine the effectiveness and sustainability of this intervention. Human factors studies showed that virtual navigation is a safe and effective method for use with chronic pain patients. Chronic pain patients demonstrated significant relief in subjective ratings of pain that corresponded to objective measurements in peripheral, noninvasive physiological measures. PMID:24892196

Chronic pain is associated with symptoms that may impair a patient's quality of life, including emotional distress, fatigue, and sleep disturbance. There is a high prevalence of concomitant pain and sleep disturbance. Studies support the hypothesis that sleep and pain have a bidirectional and reciprocal relationship. Clinicians who manage patients with chronic pain often focus on interventions that relieve pain, and assessing and treating sleep disturbance are secondary or not addressed. This article reviews the literature on pain and co-occurring sleep disturbance, describes the assessment of sleep disturbance, and outlines nonpharmacologic and pharmacologic treatment strategies to improve sleep in patients with chronic pain.

A statistical analysis of the separability of EEG A-phases, with respect to basal activity, is presented in this study. A-phases are short central events that build up the Cyclic Alternating Pattern (CAP) during sleep. The CAP is a brain phenomenon which is thought to be related to the construction, destruction and instability of sleep stages dynamics. From the EEG signals, segments obtained around the onset and offset of the A-phases were used to evaluate the separability between A-phases and basal sleep stage oscillations. In addition, a classifier was trained to separate the different A-phase types (A1, A2 and A3). Temporal, energy and complexity measures were used as descriptors for the classifier. The results show a percentage of separation between onset and preceding basal oscillations higher than 85 % for all A-phases types. For Offset separation from following baseline, the accuracy is higher than 80 % but specificity is around 75%. Concerning to A-phase type separation, A1-phase and A3-phase are well separated with accuracy higher than 80, while A1 and A2-phases show a separation lower than 50%. These results encourage the design of automatic classifiers for Onset detection and for separating among A-phases type A1 and A3. On the other hand, the A-phase Offsets present a smooth transition towards the basal sleep stage oscillations, and A2-phases are very similar to A1-phases, suggesting that a high uncertainty may exist during CAP annotation.

In the last few decades, increasing understanding of the pathomechanisms involved in chronic urticaria has highlighted the heterogeneity of different subtypes, and chronic urticaria is now classified as chronic spontaneous urticaria and inducible urticaria. Although many factors are thought to be involved in chronic urticaria, the etiology is yet to be clarified. The purpose of this study was to investigate etiological factors in patients with chronic urticaria. Five hundred patients with chronic urticaria, 351 women and 149 men, were studied for etiological factors. The autologous serum skin test was performed on 197 patients. Provocation testing for physical urticaria was performed on 354 patients. Patients with acute urticaria were excluded from the study. We determined at least one focus of infection that might be involved in the etiology of the disease in 18.8% of cases. Patients with infections were treated, and symptoms resolved after treatment in six cases (5.3%). Autologous serum skin tests were positive in 125 patients (63.5%). Provocation tests for physical urticaria were positive in 131 (37%) patients with urticaria. We suggest that physical stimuli and autoantibodies play an important role in the etiopathogenesis of urticaria.

BACKGROUND: SentenceShaper((R)) (SSR) is a computer program that is for speech what a word-processing program is for written text; it allows the user to record words and phrases, play them back, and manipulate them on-screen to build sentences and narratives. A recent study demonstrated that when listeners rated the informativeness of functional narratives produced by chronic aphasic speakers with and without the program they gave higher informativeness ratings to the language produced with the aid of the program (Bartlett, Fink, Schwartz, & Linebarger, 2007). Bartlett et al. (2007) also compared unaided (spontaneous) narratives produced before and after the aided version of the narrative was obtained. In a subset of comparisons, the sample created after was judged to be more informative; they called this "topic-specific carryover". AIMS: (1) To determine whether differences in informativeness that Bartlett et al.'s listeners perceived are also revealed by Correct Information Unit (CIU) analysis (Nicholas & Brookshire, 1993)-a well studied, objective method for measuring informativeness-and (2) to demonstrate the usefulness of CIU analysis for samples of this type. METHODS #ENTITYSTARTX00026; PROCEDURES: A modified version of the CIU analysis was applied to the speech samples obtained by Bartlett et al. (2007). They had asked five individuals with chronic aphasia to create functional narratives on two topics, under three conditions: Unaided ("U"), Aided ("SSR"), & Post-SSR Unaided ("Post-U"). Here, these samples were analysed for differences in % CIUs across conditions. Linear associations between listener judgements and CIU measures were evaluated with bivariate correlations and multiple regression analysis. OUTCOMES #ENTITYSTARTX00026; RESULTS: (1) The aided effect was confirmed: samples produced with SentenceShaper had higher % CIUs, in most cases exceeding 90%. (2) There was little CONCLUSIONS: That the percentage of CIUs was higher in SSR-aided samples than in

Chronic pain affects nearly one-third of the American population. Chronic pain can lead to a variety of problems for a pain sufferer, including developing secondary medical problems, depression, functional and vocational disability, opioid abuse and suicide. Current pain care models are deficient in providing a necessary comprehensive approach. Most patients with chronic pain are managed by primary care clinicians who are typically ill prepared to effectively and efficiently manage these cases. A biopsychosocial approach to evaluate and treat chronic pain is clinically and economically efficacious, but unique delivery systems are required to meet the challenge of access to specialty care.

Chronic sinusitis is a major cause of morbidity today. Regional variations in the incidence of this disease have been reported. The aim of this study was to evaluate the incidence of fungal infection as the causative agent of chronic sinusitis among Iranian patients. A cross sectional hospital based study was designed; the patients underwent paranasal sinus washing and maxillary sinus biopsy. All specimens were studied by light microscopy. Fungal culturing was employed to confirm diagnosis. The patients underwent Computed Tomography for sinus evaluation. Of 162 participants, 12 samples from patients showed fungal elements, 2 of them Aspergillus fulvous (1.2%), 9 of them Alternaria species (5.56%) and 1 of them Psilomysis (0.6%). All patients presented radiologic evidence of sinusitis, ranging from mucosal thickening to total opacity. In conclusion, results obtained showed a low prevalence of fungal sinusitis among Iranian patients with chronic sinusitis. Findings also showed that Alternaria is the most causative agent.

Chronic diseases such as diabetes and heart disease are the leading causes of disability and death in the developed world. Technological interventions such as mobile applications have the ability to facilitate and motivate patients in chronic disease management, but these types of interventions present considerable design challenges. The primary objective of this paper is to present the challenges arising from the design and implementation of software applications aiming to assist patients in chronic disease management. We also outline preliminary results regarding a self-management application currently under development targeting young adults suffering from type 1 diabetes.

Cardiovascular disease constitutes the major cause of mortality in patients with chronic kidney disease. Arterial stiffness is an important contributor to the occurrence and progression of cardiovascular disease. Various risk factors, including altered hormone levels, have been suggested to be associated with arterial stiffness. Based on the background that chronic kidney disease predisposes individuals to a wide range of hormonal changes, we herein review the available data on the association between arterial stiffness and hormones in patients with chronic kidney disease and summarize the data for the general population.

Two studies are presented which describe the development of a problem-oriented psychosocial screening instrument for use in health care settings. Reliability and validity data are presented on the Chronic Illness Problem Inventory (CIPI) which demonstrate its ability to document accurately patient's specific problems in areas of physical limitations, psychosocial functioning, health care behaviors and marital adjustment. A study is also presented which compares the problems of patients with three distinct chronic illnesses: pain, obesity, and respiratory ailments. Results indicate a significantly greater severity of problems for pain patients and especially patients with multiple pain complaints. Problem areas common to all three illness groups are discussed in the context of providing better comprehensive treatment for chronically ill patients.

An analysis of the EEG signal during the B-phase and A-phases transitions of the cyclic alternating pattern (CAP) during sleep is presented. CAP is a sleep phenomenon composed by consecutive sequences of A-phases (each A-phase could belong to a possible group A1, A2 or A3) observed during the non-REM sleep. Each A-phase is separated by a B-phase which has the basal frequency of the EEG during a specific sleep stage. The patterns formed by these sequences reflect the sleep instability and consequently help to understand the sleep process. Ten recordings from healthy good sleepers were included in this study. The current study investigates complexity, statistical and frequency signal properties of electroencephalography (EEG) recordings at the transitions: B-phase--A-phase. In addition, classification between the onset-offset of the A-phases and B-phase was carried out with a kNN classifier. The results showed that EEG signal presents significant differences (p < 0.05) between A-phases and B-phase for the standard deviation, energy, sample entropy, Tsallis entropy and frequency band indices. The A-phase onset showed values of energy three times higher than B-phase at all the sleep stages. The statistical analysis of variance shows that more than 80% of the A-phase onset and offset is significantly different from the B-phase. The classification performance between onset or offset of A-phases and background showed classification values over 80% for specificity and accuracy and 70% for sensitivity. Only during the A3-phase, the classification was lower. The results suggest that neural assembles that generate the basal EEG oscillations during sleep present an over-imposed coordination for a few seconds due to the A-phases. The main characteristics for automatic separation between the onset-offset A-phase and the B-phase are the energy at the different frequency bands.

The aim of this study was to investigate the 4977 and 7400 bp deletions of mitochondrial DNA in patients with chronic suppurative otitis media and to indicate the possible association of mitochondrial DNA deletions with chronic suppurative otitis media. Thirty-six patients with chronic suppurative otitis media were randomly selected to assess the mitochondrial DNA deletions. Tympanomastoidectomy was applied for the treatment of chronic suppurative otitis media, and the curettage materials including middle ear tissues were collected. The 4977 and 7400 bp deletion regions and two control regions of mitochondrial DNA were assessed by using the four pair primers. DNA was extracted from middle ear tissues and peripheral blood samples of the patients, and then polymerase chain reactions (PCRs) were performed. PCR products were separated in 2 % agarose gel. Seventeen of 36 patients had the heterozygote 4977 bp deletion in the middle ear tissue but not in peripheral blood. There wasn't any patient who had the 7400 bp deletion in mtDNA of their middle ear tissue or peripheral blood tissue. The patients with the 4977 bp deletion had a longer duration of chronic suppurative otitis media and a higher level of hearing loss than the others (p < 0.01). Long time chronic suppurative otitis media and the reactive oxygen species can cause the mitochondrial DNA deletions and this may be a predisposing factor to sensorineural hearing loss in chronic suppurative otitis media. An antioxidant drug as a scavenger agent may be used in long-term chronic suppurative otitis media.

We investigated the prevalence of xenotropic murine leukemia virus-related virus (XMRV) in 293 participants seen at academic hospitals in Boston, Massachusetts. Participants were recruited from five groups of patients: chronic fatigue syndrome (CFS, n = 32), HIV infection (n = 43), rheumatoid arthritis (RA, n = 97), hematopoietic stem-cell or solid organ transplant (n = 26), or a general cohort of patients presenting for medical care (n = 95). XMRV DNA was not detected in any participant samples. We found no association between XMRV and patients with CFS or chronic immunomodulatory conditions. PMID:20936980

Chronic kidney disease (CKD) is a worldwide public health problem. Patients with CKD have a number of disorders in the organism, and the presence of oxidative stress and systemic inflammation in these patients is the subject of numerous studies. Chronic inflammation joined with oxidative stress contributes to the development of numerous complications: accelerated atherosclerosis process and cardiovascular disease, emergence of Type 2 diabetes mellitus, development of malnutrition, anaemia, hyperparathyroidism, and so forth, affecting the prognosis and quality of life of patients with CKD. In this review we presented the potential role of the myeloperoxidase enzyme in the production of reactive/chlorinating intermediates and their role in oxidative damage to biomolecules in the body of patients with chronic kidney disease and end-stage renal disease. In addition, we discussed the role of modified lipoprotein particles under the influence of prooxidant MPO intermediates in the development of endothelial changes and cardiovascular complications in renal failure.

Compared effects of six sessions of group counseling of nine chronic home hemodialysis patients with a comparable no treatment control group. Comparisons revealed no significant differences between groups. Subsequent testing a year later suggested that hemodialysis patients use the defensive mechanism of denial in adapting to their condition.…
National and international awareness of the heavy burden of chronic disease has led to the development of new strategies for managing care. Elisabeth Bryant explains how self-care, education and support for more patients with complex needs should be built into planned care delivery, and emphasises that the patient is the key member of the care team.

A great number of basic and clinical studies have demonstrated that inflammatory cytokines play an important role in development and progress of heart failure. However, there is limited information about allergic cytokine interleukin-13 (IL-13). The inflammatory responses mediated by allergic cytokines can cause significant morbidity and mortality when they become chronic. Therefore, we elucidated the role of IL-13 in the pathophysiology of chronic heart failure. We measured plasma IL-13 levels by enzyme-linked immunosorbent assay in 110 patients with chronic heart failure and 20 control subjects. Plasma IL-13 levels were increased in heart failure patients, compared with the controls, in association with NYHA functional class. In addition, IL-13 levels were correlated positively with plasma levels of brain natriuretic peptide and C-reactive protein, and negatively with left ventricular ejection fraction. Plasma IL-13 levels may be useful for evaluating disease severity in chronic heart failure.

Patients with chronic kidney disease (CKD) develop bleeding and thrombotic tendencies, so the indication of anticoagulation at the onset of atrial fibrillation (AF) is complex. AF is the most common chronic cardiac arrhythmia, and thromboembolism and ischemic stroke in particular are major complications. In recent years, new oral anticoagulant drugs have been developed, and they have shown superiority over the classical AVK in preventing stroke, systemic embolism and bleeding risk, constituting an effective alternative to those resources.

Background Neuropathic characteristics are highly involved in the development of chronic pain both physically and psychologically. However, little is known about the relationship between neuropathic characteristics and brain morphological alteration. Objectives The aim of this study is to investigate the mechanisms of chronic pain development by examining the above-mentioned relationships by voxel-based morphometry in patients with chronic pain. Methods First, we assessed neuropathic characteristics using the painDETECT Questionnaire in 12 chronic pain patients. Second, to assess the gray matter volume changes by voxel-based morphometry, we conducted magnetic resonance imaging of the brain. We applied multiregression analysis of these two assessment methods. Results There were significant positive correlations between painDETECT Questionnaire scores and the gray matter volume in the bilateral anterior cingulate cortex and right posterior cingulate cortex. Conclusions Our findings suggest that neuropathic characteristics strongly affect the brain regions related to modulation of pain in patients with chronic pain and, therefore, contribute to the severity of chronic pain.

Migraine is a neurovascular disorder characterized by autonomic nervous system dysfunction and severe headache attacks. Studies have shown that changes in the intracranial vessels during migraine have an important role in the pathophysiology. Many studies have been conducted on the increased risk of stroke in patients with migraine, but insufficient data are available on the mechanism underlying the increase. This study aimed to evaluate basal cerebral blood flow velocity and vasomotor reactivity in patients with chronic migraine. We evaluated 38 patients with chronic migraine. Three of them were excluded because they had auras and four of them were excluded because of their use of medication that can affect cerebral blood flow velocity and breath holding index (beta or calcium channel blockers). Our study population consisted of 31 patients with chronic migraine without aura and 29 age- and gender-matched healthy individuals who were not taking any medication. The mean blood flow velocity and breath holding index were measured on both sides from the middle cerebral artery and posterior cerebral artery, with temporal window insonation. The breath holding index for middle cerebral artery and posterior cerebral artery was significantly lower in the migraine group compared to that of the control group (p < 0.05).The vasomotor reactivity indicates the dilatation potential of a vessel, and it is closely related to autoregulation. According to our results, the vasodilator response of cerebral arterioles to hypercapnia was lower in patients with chronic migraine. These findings showed the existence of impairments in the harmonic cerebral hemodynamic mechanisms in patients with chronic migraine. This finding also supports the existing idea of an increased risk of stroke in patients with chronic migraine due to impaired vasomotor reactivity.

Patient education plays an important role in chronic disease management. The aim of this study is to identify patients' preferences in regard to the design features of effective online patient education (OPE) and the benefits. A review of the existing literature was conducted in order to identify the benefits of OPE and its essential design features. These design features were empirically tested by conducting survey with patients and caregivers. Reliability analysis, construct validity and regression analysis were performed for data analysis. The results identified patient-tailored information, interactivity, content credibility, clear presentation of content, use of multimedia and interpretability as the essential design features of online patient education websites for chronic disease management.

Thyroid hormone level may be altered in chronic renal failure patients. Low levels of thyroxine protect the body from excess protein loss by minimizing catabolism. Hyperthyroidism is rarely encountered in end-stage dialysis dependent patients. Less than 10 well-documented cases of Graves' disease (GD) are reported in literature so far. We report a case of GD in a patient on dialysis. PMID:25484538

The health of an individual depends on both his/her physical and psychological condition. In recent years it has been observed that chronic patients have frequently an affected psycho-emotional state. The purpose of this study is to investigate anxiety and depression in patients with chronic diseases and the correlation of the results with daily physical activity levels and individual health levels, as well comorbidity. This study included patients with chronic diseases that were treated in a local general hospital or were visiting often outpatient clinics of the same hospital due to their condition. The sample in this particular study included 204 patients; 118 of them were women and 86 men. From the total sample that participated in our research, 118 (57.8%) were females and the majority of the participants were secondary/basic education graduates (67%), married (71%), living in urban areas (53%). Hypertension was the most frequent chronic disease in our sample, followed by hypercholesterolemia and diabetes mellitus. Comparing the occurrence of depression and anxiety symptoms in both questionnaires in relation to the expected frequency in the general population, significant levels of depression and anxiety symptoms were recorded. Taking into consideration the findings of this research, anxiety and depression symptoms can have profound effects regarding the control of chronic diseases, the patients’ quality of life and their general health.

It has been reported that 10-50% of patients with pruritus but no skin rash have an underlying systemic disease and up to 70% a psychiatric one. The aim of this retrospective study was to review the records of a large number of patients with chronic pruritus for concomitant diseases and treatment options. Medical records of 139 patients (52 males, 87 females) with chronic pruritus who visited the outpatient dermatological clinic during a 17-month period were reviewed. Itch was the presenting symptom in 6 of 47 patients with systemic disease and in 17 of 31 patients with psychiatric disease. Twenty-four patients had neuropathic itch and 37 patients had pruritus of unknown origin. The most severe and long-lasting itch was found in patients with multiple systemic diseases and in those with pruritus of unknown origin. Pruritus of the scalp and face was most common in psychogenic pruritus. Phototherapy was found to be a useful therapeutic option. In conclusion, systemic diseases are unlikely to cause chronic pruritus in patients consulting a dermatology department.

Increased sympathetic and reduced vagal activity predict increased mortality in patients with congestive heart failure (CHF). Experimentally, vagal stimulation (VS) is protective both during acute myocardial ischemia and in chronic heart failure. In man, VS is used in refractory epilepsy but has never been used in cardiovascular diseases. Thus, there is a strong rationale to investigate the effects of chronic VS in patients with CHF. We assesses the feasibility and safety of chronic VS with CardioFit (BioControl Medical), a VS implantable system delivering pulses synchronous with heart beats to the right cervical vagus nerve in a preliminary pilot study in eight advanced CHF patients with favorable results, and subsequently in a larger multicenter study. Overall, 32 patients have been successfully implanted (mostly in NYHA Class III; mean age 56 years, ischemic etiology in 69%; prior implantable cardioverter-defibrillator (ICD) in 63%; concomitant beta blocker and angiotensin converting enzyme inhibitor (ACE-I) or angiotensin receptor blocker (ARB) in 100%). Preliminary results confirm feasibility of the study, an acceptable side effect profile and promising preliminary efficacy data. Several mechanisms may contribute to the beneficial effect observed in patients with heart failure. Should these results be confirmed in larger controlled studies, chronic vagal stimulation could be a further treatment option for CHF patients, possibly integrated with defibrillator and resynchronization therapies.

The `gold standard' therapy for patients with symptomatic bladder outlet obstruction secondary to benign prostatic hyperplasia has always been electrocautery TURP. However, in patients with medical problems requiring chronic anticoagulation, this procedure is contraindicated due to the extreme risk of hemorrhage, both during the procedure and the immediate post operative period. With the recent development of contact laser prostatectomy the patient on chronic anticoagulation can safely undergo the procedure. Herein, I present a case of a 60 year old with significant bladder outlet obstruction yielding an AUA symptom score of 18. The patient had a history of multiple episodes of deep venous thrombosis of the left leg with three prior pulmonary emboli. He was maintained on chronic anticoagulation with alternating days of 3.5 mg. and 5.0 mg. of warfarin sodium (coumadin). Preoperative cystoscopy showed a 4 cm prostatic fossa obstructed by tri-lobar hypertrophy, with large kissing lateral lobes and visual obstruction from the verumontanum. The patient underwent a contact laser prostatectomy with the SLT Nd:YAG laser at 50 watts. There was minimal bleeding both during the procedure and in the immediate postoperative period. At three months post-op the AUA symptom score had decreased to 2. This case demonstrated that contact laser prostatectomy can be safely and effectively performed in patients on chronic anticoagulation.

The response definitions proposed by the European Leukemia Net (ELN) have been recently modified. We evaluated the new criteria for de novo imatinib (400 mg/d) chronic phase chronic myeloid leukemia (CP-CML) patients. Response status according to the 2009 and 2013 criteria were determined in 180 unselected patients. Outcome of the subgroups of patients were then compared. The 180 patients were classified as optimal responders (OR2009; n = 113, 62.7%), suboptimal responders (SOR2009; n = 47, 26.1%) and failures (FAIL2009; n = 20, 11.1%) according to the 2009 ELN criteria and optimal responders (OR2013; n = 77, 42.7%), warnings (WAR2013; n = 59, 32.7%), and failures (FAIL2013; n = 44, 24.4%) according to the 2013 ELN criteria. No difference in terms of outcome was observed between OR2009 patients who became WAR2013 when compared with OR2013 patients. When compared with FAIL2009 patients, SOR2009 patients who became WAR2013 had better EFS, FFS, PFS, and OS. No difference was observed in PFS or OS in SOR2009 patients who became FAIL2013. The 2013 ELN response status criteria have improved patients classification in terms of response status. However, in our patient population this improvement is related to a better definition of failure rather than that of optimal response for CP-CML patients treated with IM frontline therapy.

The increase in chronic diseases and the progressive ageing of the population is a source of concern for the different agencies with responsibility for health care. This has led to the creation of many documents focused on the analysis of the current situation and care of chronic diseases, including the WHO recommendations intended to assist countries and health services design and implement strategies that will address the existing demand, control and prevention of chronic diseases. In addition, there is a need to respond to the demand generated by chronic diseases in every sense, and from the different systems it is becoming more difficult to get enough support from multidisciplinary teams where the nurse has a central importance. While chronic diseases are becoming a threat due to the costs they generate, it is also an opportunity for nursing to be at the forefront for advanced care requirements, performed by professionals with recognized advanced clinical skills and ability for case management while monitoring and controlling complex chronic patients. The different services of the National Health System have introduced nurses that play different roles (cases managers, liaison nurses, advanced practice nurses and so on). However, it could be argued that they are not being trained to a desirable development level. It is therefore time for health care authorities to determine the role of the advanced practice nurse in relation to functional positions, and allow them to make an advance in the development of unified skills for the whole National Health System. From our experience we have learned that the advanced practice nurse is a resource that helps in the sustainability of services, thanks to the efficiency shown in the results obtained from the care given to both chronic and complex chronic patients.

Healthcare managers are more and more interested in the role of general practitioners (GP) in the treatment of cardiovascular diseases. Continuing adjustments of the health organization are the old/new challenge in improving patient care. The European Society of Cardiology guidelines recommend a disease-management program for heart failure (HF); moreover, observational studies and randomized controlled trials have reported better patient outcomes if patients are in charge of cardiologists rather than GPs or other physicians. Patients with chronic HF are often very old and affected by multiple comorbid conditions, by themselves associated with high rates of morbidity and mortality. Furthermore, too many patients receive neither a correct diagnosis nor treatment until advanced disease occurs. New treatment approaches, some of them requiring the expertise of well-trained cardiologists, are ongoing to improve the clinical outcomes. The optimal management of patients with HF needs teamwork, i.e. GPs, cardiologists, nurses and caregivers, since a multidisciplinary program, only, can embody the best answer for outpatients with chronic HF. Currently, the Cardiovascular Center in Trieste is performing an experimental trial, so far never attempted before, in treating patients with chronic HF using a thorough approach with the full involvement of local cardiologists, GPs and nurses. Such approach is, at the same time, as well a challenge as an opportunity: a challenge because conventional clinical habits must be changed; an opportunity because patients can benefit from a proper whole care-group, aimed at prolonging life and reducing morbidity and symptoms.

A deterioration in information-processing performance is commonly recognized in patients with chronic schizophrenia. Although the enhancement of cognitive skills in patients with schizophrenia is important, the types of external stimuli that influence performance have not received much attention. The aim of present study was to clarify the effects of spatial and affordance compatibility in patients with schizophrenia, compared with those in healthy people. The subjects (25 patients with schizophrenia and 25 healthy controls) participated in two experiment examining the effects of the spatial location of stimuli and the action-relevance of objects. The results showed that the effect of spatial compatibility was similar in both the patients and the controls, whereas the influence of action-relevant objects was not highlighted in either patients with chronic schizophrenia or healthy controls. These findings provide important evidence of a normal spatial compatibility effect in patients with chronic schizophrenia. However, further research examining the affordance compatibility effect is needed, taking into consideration the symptomatology and the severity of the social functioning level in patients with schizophrenia.

For 9 months we evaluated a portable device to transfer patient-clinician data by Internet: oximetry, ECG, clinical questionnaires and messages from the doctor. Fifty-one patients with severe chronic respiratory insufficiency (CRI) were followed at the hospital Pulido Valente and Espírito Santo and 21 asthmatics (A) were followed at the latter hospital. The use and acceptance of this device was evaluated through questionnaires soliciting patients' and health professionals' opinions. Patients with CRI followed in Lisbon were also asked about hospital admissions and quality of life compared with a nine month period before the monitoring programme. CRI patients found learning to use the system more difficult; the majority (80%) reported problems with the equipment, qualified as rare/occasional in 62% of the cases. For 31 CRI patients followed in Lisbon, the use of the system was classified as correct in 12 patients, incorrect in 7 and reasonable in 12 patients. The first group had a reducded number and duration of hospital admissions and also improved quality of life. With this remote monitoring system 80% of CRI patients reported they were more/much more supported and 33 patients (75%) would use this system in the future. 81% of asthmatic patients would also like to maintain this type of monitoring. The service was considered useful by the researchers. We concluded that home telemonitoring was a positive contribution to the management of chronic patients and raised awareness of it should be considered in the future.

Chronic systemic inflammation, a non traditional risk factor of cardiovascular diseases, is associated with increasing mortality in chronic kidney disease, especially peritoneal dialysis patients. Periodontitis is a potential treatable source of systemic inflammation in peritoneal dialysis patients. Clinical periodontal status was evaluated in 32 stable chronic peritoneal dialysis patients by plaque index and periodontal disease index. Hematologic, blood chemical, nutritional, and dialysis-related data as well as highly sensitive C-reactive protein were analyzed before and after periodontal treatment. At baseline, high sensitive C-reactive protein positively correlated with the clinical periodontal status (plaque index; r = 0.57, P < 0.01, periodontal disease index; r = 0.56, P < 0.01). After completion of periodontal therapy, clinical periodontal indexes were significantly lower and high sensitivity C-reactive protein significantly decreased from 2.93 to 2.21 mg/L. Moreover, blood urea nitrogen increased from 47.33 to 51.8 mg/dL, reflecting nutritional status improvement. Erythropoietin dosage requirement decreased from 8000 to 6000 units/week while hemoglobin level was stable. Periodontitis is an important source of chronic systemic inflammation in peritoneal dialysis patients. Treatment of periodontal diseases can improve systemic inflammation, nutritional status and erythropoietin responsiveness in peritoneal dialysis patients.

This study reports the results of a researcher-administered survey with 115 patients receiving chronic opioid therapy (>90 days) to obtain information regarding how chronic opioid therapy was started. Chronic opioids were started after surgery (27.0%, 95% confidence interval [CI], 18.5-35.5) or for the treatment of acute injury-related pain (27.0%, 95% CI, 18.5-35.5). Many who initiated opioid therapy after surgery reported postoperative complications (61.3%, 95% CI, 50.8-71.8) and many with injury-related pain reported follow-up corrective surgery (58.1%, 95% CI, 47.5-68.7), which led to the continuation of opioids. A large percentage of patients had concurrent depression (43.5%, 95% CI, 34.0-53.0) and anxiety (23.5%, 95% CI, 15.3-31.7). Many participants had a medical history of aberrant drug-related behavior (32.5%, 95% CI, 23.5-41.5) and self-reported history of addiction (21.7%, 95% CI, 13.7-29.7). Almost one-quarter reported taking opioids for a different indication than that for which opioids were started (95% CI, 26.6-45.0). Patients receiving long-term opioid therapy often transitioned to chronic use after starting opioids for the short-term treatment of postoperative or injury-related pain. It is not evident if a clear decision to continue opioids on a chronic basis was made. This survey provides insight as to how chronic opioid therapy is started, and may suggest opportunities for improved patient selection for opioid therapy.

Apnea is a commonest complaint in aged patients. It may be due to chronic cardiac insufficiency (CCI) and chronic obstructive pulmonary disease (COPD). The prevalence of CCI in the general populations and among 65 year old subjects is 1.8 and 6-10% respectively, decompensation being the most frequent cause of hospitalization of elderly patients. Different authors report CCI in 30-62% of the elderly patients with COPD. Combination of CCI and COPD create difficulties for diagnostics and treatment due to late detection of CCI, common risk factors and pathogenetic features of the two conditions their similar clinical picture. This paper is designed to consider methods of CCI diagnostics in patients with COPD. Special emphasis is laid on the thorough analysis of medical histories, specific laboratory tests (BNP NT-proBNP), and instrumental methods (echocardiogram, MRI, spirography, X-ray studies).

Metabolism of nitrendipine occurs principally in the liver. Therefore, an alteration of pharmacokinetics has to be discussed in patients with hepatic impairment. To evaluate steady-state plasma concentrations and pharmacokinetics, a low dose of nitrendipine (5 mg/day for 3 weeks) was administered orally to patients with different chronic liver diseases (fatty liver, n = 3; chronic hepatitis, n = 2; and cirrhosis of the liver, n = 5). Nitrendipine plasma concentrations were analyzed by using a gas-liquid chromatography procedure. Twenty-two days after beginning the study, steady-state plasma concentrations were lower than 1.0 microgram/L in one patient without liver disease and in seven patients with chronic liver diseases, in contrast to three patients with alcoholic cirrhosis (5.5, 1.3, and 2.9 micrograms/L). The maximum concentration (Cmax) was 2.3 micrograms/L in the patient without liver disease and 8.3 +/- 3.9 micrograms/L in the hepatic patients. The elimination half-life was prolonged in three of five patients with cirrhosis of the liver (35, 67, and 43 h), whereas in the other patients the half-life was in a normal range (4.2-21.3 h). The area under the concentration-time curve (AUC) was enhanced in three patients with liver cirrhosis (387, 69, and 126 h/micrograms/L); in the other seven hepatic patients, results were normal (35-49 h/micrograms/L). There were no alterations observed in any patient in blood pressure and laboratory data. Oral administration of a low dose of nitrendipine resulted in slightly enhanced steady state plasma concentrations only in patients with advanced cirrhosis of the liver. The half-life, AUC, and bioavailability also seem to be altered only in a more severe state of liver disease.

Heart failure (HF) poses a significant economic burden on our health-care resources with very high readmission rates. Remote monitoring has a substantial potential to improve the management and outcome of patients with HF. Readmission for decompensated HF is often preceded by a stage of subclinical hemodynamic decompensation, where therapeutic interventions would prevent subsequent clinical decompensation and hospitalization. Various methods of remote patient monitoring include structured telephone support, advanced telemonitoring technologies, remote monitoring of patients with implanted cardiac devices such as pacemakers and defibrillators, and implantable hemodynamic monitors. Current data examining the efficacy of remote monitoring technologies in improving outcomes have shown inconsistent results. Various medicolegal and financial issues need to be addressed before widespread implementation of this exciting technology can take place.

Chronic asymptomatic elevation of pancreatic enzymes is a well known entity although little has been reported. In most cases chronic asymptomatic elevation of amylase is due to a salival isoamylase increase or macroamylasemia. However, we have studied 10 cases with an increase in amylases due to pancreatic isoamylase and an increase in the remaining pancreatic enzymes which remained elevated during the follow up period ranging from 2 to 60 months. The amylase values ranged from 186 to 1,600; the lipase from 176 to 3,989, trypsin from 476 to 2,430 and pancreatic isoamylase from 122 to 1,263. In all patients CT and echography were carried out, which discarded structural damage. Nonetheless, an indirect test of pancreatic function presented unexplained pathologic values in 4 out of 10 patients. In conclusion, we suggest that chronic asymptomatic elevation of pancreatic enzymes is of unknown etiology with no associated structural pancreatic pathology demonstrable by the usual study methods.

Objective To describe the perspectives and experiences of chronic hemodialysis (CHD) patients regarding self-care and adherence to fluid restrictions. Design Semi-structured focus groups. Setting Two outpatient hemodialysis centers. Participants 19 patients on chronic hemodialysis. Intervention Patients were asked a series of open-ended questions to encourage discussion about the management of fluid restriction within the broad categories of general knowledge, knowledge sources or barriers, beliefs and attitudes, self-efficacy, emotion, and self-care skills. Main outcome measure We analyzed session transcripts using the theoretical framework of content analysis to identify themes generated by the patients. Results Patients discussed both facilitators and barriers to fluid restriction which we categorized into 6 themes: knowledge, self-assessment, psychological factors, social, physical, and environmental. Psychological factors were the most common barriers to fluid restriction adherence, predominantly involving lack of motivation. Knowledge was the most discussed facilitator with accurate self-assessment, positive psychological factors, and supportive social contacts also playing a role. Dialysis providers were most commonly described as the source of dialysis information (54%), but learning through personal experience was also frequently noted (28%). Conclusion Interventions to improve fluid restriction adherence of chronic hemodialysis patients should target motivational issues, assess and improve patient knowledge, augment social support, and facilitate accurate self-assessment of fluid status.

Introduction The presence of background HCV infection cannot be overestimated in view of the prevalence of chronic hepatitis C and the risk of adverse outcomes of this disease. Purpose of this study was to evaluate the effectiveness of the combined use of antiviral therapy (Roferon + Vero-Ribavirin) and resort factors in patients with chronic hepatitis C in the phase of replication. Material and methods We observed 48 patients with chronic hepatitis C; the minimum level of activity of the process defined the phase of replication. Markers of HCV infection were determined by enzyme linked immunosorbent assay (ELISA) (a-HCV and HCV-Ig M). HCV RNA was determined twice by the polymerase chain reaction (PCR). Genotyping of hepatitis C virus was performed. Biochemical blood analysis and the study of HCV infection markers were carried out four times. Results of therapy were assessed immediately after the end of the resort (spa) treatment, then at 3, 6 and 12 months after starting treatment. At 12 months after starting treatment, all the observed patients had persistent clinical and biochemical remission. Elimination of the virus from the blood was noted in 56% of the control group and 74% of patients in the study group. Conclusions For patients with moderately active HCV, the replication phase was characterized by asthenic-vegetative syndrome (100% of patients) with severe depression (22.92%), pain (77.08%) and dyspeptic syndrome (33.33%), moderate hypertransferaseemia (100%), slightly pronounced cholestasis (33% of patients), and signs of mesenchymal-inflammatory response.

Among patients on dialysis, hypertension is highly prevalent and contributes to the high burden of cardiovascular morbidity and mortality. Strict volume control via sodium restriction and probing of dry weight are first-line approaches for the treatment of hypertension in this population; however, antihypertensive drug therapy is often needed to control BP. Few trials compare head-to-head the superiority of one antihypertensive drug class over another with respect to improving BP control or altering cardiovascular outcomes; accordingly, selection of the appropriate antihypertensive regimen should be individualized. To individualize therapy, consideration should be given to intra- and interdialytic pharmacokinetics, effect on cardiovascular reflexes, ability to treat comorbid illnesses, and adverse effect profile. β-Blockers followed by dihydropyridine calcium-channel blockers are our first- and second-line choices for antihypertensive drug use. Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers seem to be reasonable third-line choices, because the evidence base to support their use in patients on dialysis is sparse. Add-on therapy with mineralocorticoid receptor antagonists in specific subgroups of patients on dialysis (i.e., those with severe congestive heart failure) seems to be another promising option in anticipation of the ongoing trials evaluating their efficacy and safety. Adequately powered, multicenter, randomized trials evaluating hard cardiovascular end points are urgently warranted to elucidate the comparative effectiveness of antihypertensive drug classes in patients on dialysis. In this review, we provide an overview of the randomized evidence on pharmacotherapy of hypertension in patients on dialysis, and we conclude with suggestions for future research to address critical gaps in this important area.

In the Greek pilot of the e-Vital project, remote telemedicine services are provided to chronic cardiac and pulmonary patients who are not confined to a hospital (i.e. receiving home/ambulatory health care) with the aim of exploring the dynamics of interactive continuous chronic patient monitoring, particularly focusing on the impact on patient's quality of life, the patient's active involvement in their own care and according impact on the overall quality of healthcare provision, as well as the benefits for healthcare providers (time management, patient management, savings, etc). The current trial in progress validates the business potential of remote monitoring services and demonstrates the technical environment that enables patient-doctor interaction regardless of location and the according communication modes and protocols. The domain for applying the envisaged service is the private healthcare sector and the users groups include individual chronic patients with cardiac and pulmonary diseases. So far, from the patient's point of view, the service mainly appeals to patients with arrhythmias due to lightweight technology and easy processes involved in the transmission of 1-lead ECG. Asthma and COPD patients are also enthusiastic, as they can receive doctor advice in real time. From the health professional's point of view the service has real added value in the fields of diagnosis, prevention, monitoring and follow up. In the case of asthma and COPD the value of the service in diagnosis is even more apparent as these patients may be asymptomatic, when they visit their doctor and have exacerbations when they are at home. e-Vital in this case ensures that the healthcare professional will acquire the complete image of the patient condition. Finally, the experiences gained so far indicate that e-Vital could be particularly efficient in isolated areas, with shortage of experienced scientific personnel.
The faulty use of compound nouns by aphasics is of practical and theoretical significance. Defects in the finding and using of compound nouns were investigated with respect to the following parameters: the importance of the frequency with which compounds and compound parts are used in normal speech, the influence of grammatical and psycholinguistic peculiarities on aphasic dysfunction, and the handling of compounds in individual aphasic syndromes. The distinctly poorer recall of compound nouns compared with simple nouns was found to be due mainly to their less frequent use in normal speech. In word-finding the grammatical unit of the compound noun was not very stable patholinguistically. If one part of the compound noun was commoner and more usual in normal speech than the other it was usually better recalled. However, some remarkable deviations from this were due to semantic functional value, vividness, morphologic peculiarities, and linguistic form. The wider meaning-range of the second part of the compound noun had no positive mnemonic effect, despite the propensity of the aphasic for the general. In naming tests the first part of the compound noun was preferred on average. Certain differences in the defective use of compound nouns were observed between the individual aphasic syndromes.

A 37-item survey covering a variety of somatopsychic domains was constructed to explore patients' subjective response to treatment with clozapine. The survey was administered to 130 patients with diagnoses of chronic schizophrenic or schizoaffective disorders who were on a stable clozapine regimen. The majority reported improvement in their level of satisfaction, quality of life, compliance with treatment, thinking, mood, and alertness. Most patients reported worsening in nocturnal salivation, and smaller numbers reported worsening in various gastrointestinal and urinary symptoms and weight gain. This general health survey highlights the patients' positive regard for clozapine, despite adverse bodily experiences. Subjective reports are a useful component of outcome measures of drug treatment.

Methylphenidate is frequently prescribed for attention deficit hyperactivity disorder, narcolepsy, and other sleep disorders requiring psychostimulants. Our report is based on 2 different clinical experiences of patients with chronic methylphenidate use, undergoing general anesthesia. These cases contrast different strategies of taking versus withholding the drug treatment on the day of surgery. From the standpoint of anesthetic management and patient safety, the concerns for perioperative methylphenidate use are mainly related to cardiovascular stability and possible counteraction of sedatives and anesthetics.

Chronic low back pain (LBP) is an extremely common problem in practice, where it is often labeled idiopathic. No sufficient studies have been conducted to analyze the contribution of hypovitaminosis D to the etiology of chronic LBP in populations wherein vitamin D deficiency is endemic. The present study was, therefore, carried out to examine hypovitaminosis D and its determinants in female patients with chronic LBP during the childbearing period. Sixty female patients complaining of LBP lasting more than 3 months were clinically studied rheumatologically and neurologically. Questionnaires and indices quantifying risk factors associated with vitamin D deficiency were utilized. Biochemical assays of serum calcium, phosphorus, alkaline phosphatase (ALP), parathormone (PTH), and 25-hydroxyvitamin D (25 OHD) were performed and compared to those of 20 matched healthy controls. The determinants of vitamin D levels in patients were examined by stepwise regression. Patients with LBP had significantly lower 25 OHD levels (p < 0.05) and significantly higher PTH (p < 0.05) and ALP (p < 0.001) than controls, although there were no significant group differences in calcium and phosphorus. Hypovitaminosis D (25 OHD < 40 ng/ml) was found in 49/60 patients (81%) and 12/20 (60%) of controls, with an odds ratio of 2.97. Although many risk factors related to sun exposure, clothing, diet, and pregnancy were significantly correlated with vitamin D levels in patients, only limited duration of sun exposure, contributing 55% to the variance of 25 OHD, limited areas of skin exposed (13%), and increased number of pregnancies (2%), were significant determinants of vitamin D levels in patients. Despite the sunny climate, hypovitaminosis D is prevalent among Egyptian women in the childbearing period, especially those presenting with chronic LBP, where it is associated with hyperphosphatasia and hyperparathyroidism, without alterations in serum calcium. The major determinant of hypovitaminosis D

We report a patient with headaches meeting the criteria of chronic paroxysmal hemicrania, as defined by the International Headache Society classification. Headaches were fully responsive to indomethacin during the first 3 months of treatment but recurred when daily doses were lowered. Investigations revealed a macroprolactinoma. Headaches stopped after cabergoline treatment. This report further suggests that patients with paroxysmal hemicrania should be investigated for pituitary abnormalities.

Cryptococcosis is a systemic mycosis usually affecting patients of immunodeficiency i.e. transplants recipients, patients on chemotherapy for neoplastic diseases and in those suffering from human immunodeficiency virus infection. We report a 52-year old male suffering from chronic lymphocytic leukemia (CLL) on chemotherapy who presented with fever and features of prostatism. Cryptococcus neoformans infection (CN) was diagnosed on aspiration of a prostatic nodule. Subsequent investigations revealed a disseminated involvement by cryptococcus. The case represents an unusual presentation of disseminated cryptococcosis.

Halotherapy proved to be a highly effective method in a complex sanatorium treatment of patients with chronic bronchitis. Its use promotes more rapid liquidation of clinical manifestations of disease, improves indices of vent function of lungs, especially those values that characterize bronchial conduction (volume of forced exhalations per second, index Tiffno), increases tolerance to physical load, normalizes indices of reduced immunity and leads to increasing the effectiveness of patient treatment in sanatorium.

Many chronic conditions with fluctuating levels of disease activity are traditionally managed by lifelong regular medical reviews. However, this means appointments do not always coincide with patient need, while the volume of reviews makes it difficult to respond quickly to requests for help. Research in rheumatoid arthritis suggests that hospital-initiated reviews can be replaced by patient-initiated reviews, supported by nurse-led initiatives.

STUDY OBJECTIVE: To assess the incidence of pulmonary hypertension (PH) in patients with chronic myeloproliferative disorders (CMPD). METHOD: Twenty-seven patients with a diagnosis of CMPD were included in the study. Patients were excluded if they had a secondary cause of PH. Diagnosis of PH was established if right ventricular systolic pressure (RVSP) by transthoracic echocardiography (TTE) was >35 mmHg. RESULTS: Diagnosis of PH was established in 14 out of 27 patients. Two patients were excluded from analysis because of poor ejection fraction on TTE, resulting in a final diagnosis of PH in 12 of 25 (48%) patients. Of these 25 patients, seven of nine with essential thrombocytosis (ET), five of 14 with polycythemia vera (PV), and 0 out of two with chronic myeloid leukemia (CML) had PH. All patients were asymptomatic at the time of their most recent visit. There was no relationship between PH and age at diagnosis, duration of disease, platelet count and hematocrit at diagnosis or during follow-up, both for the entire cohort or for specific diagnosis of ET or PV. CONCLUSION: Pulmonary hypertension appears to be common in patients with CMPD. Further studies are needed to evaluate the impact of treatment on PH and long-term survival in these patients.

We evaluated immediate and long-term results of percutaneous transluminal angioplasty (PTA) and stent placement to treat stenotic and occluded arteries in patients with chronic mesenteric ischemia. Fourteen patients were treated by 3 exclusive celiac artery (CA) PTAs (2 stentings), 3 cases with both Superior Mesenteric Artery (SMA) and CA angioplasties, and 8 exclusive SMA angioplasties (3 stentings). Eleven patients had atheromatous stenoses with one case of an early onset atheroma in an HIV patient with antiphospholipid syndrome. The other etiologies of mesenteric arterial lesions were Takayashu arteritis (2 cases) and a postradiation stenoses (1 case). Technical success was achieved in all cases. Two major complications were observed: one hematoma and one false aneurysm occurring at the brachial puncture site (14.3%). An immediate clinical success was obtained in all patients. During a follow-up of 1-83 months (mean: 29 months), 11 patients were symptom free; 3 patients had recurrent pain; in one patient with inflammatory syndrome, pain relief was obtained with medical treatment; in 2 patients abdominal pain was due to restenosis 36 and 6 months after PTA, respectively. Restenosis was treated by PTA (postirradiation stenosis), and by surgical bypass (atheromatous stenosis). Percutaneous endovascular techniques are safe and accurate. They are an alternative to surgery in patients with chronic mesenteric ischemia due to short and proximal occlusive lesions of SMA and CA.
The concept of “expert patient” has been developed in the last two decades to define a patient who has a significant knowledge of his/her disease and treatment in addition to self-management skills. However, this concept has evolved over the last years, and these patients are now considered, not only to be more efficient in the management of their own condition and communicating effectively with health professionals, but to also act as educators for other patients and as resources for the last, provide feedback on care delivery, and be involved in the production and implementation of practice guidelines, as well as in the development and conduct of research initiatives. There are some barriers, however, to the integration of this new contributor to the health care team, and specific requirements need to be considered for an individual to be considered as an expert. This new player has, however, a potentially important role to improve current care, particularly in respiratory health. PMID:27445572

[Purpose] Through core strength training, patients with chronic low back pain can strengthen their deep trunk muscles. However, independent training remains challenging, despite the existence of numerous core strength training strategies. Currently, no standardized system has been established analyzing and comparing the results of core strength training and typical resistance training. Therefore, we conducted a systematic review of the results of previous studies to explore the effectiveness of various core strength training strategies for patients with chronic low back pain. [Methods] We searched for relevant studies using electronic databases. Subsequently, we evaluated their quality by analyzing the reported data. [Results] We compared four methods of evaluating core strength training: trunk balance, stabilization, segmental stabilization, and motor control exercises. According to the results of various scales and evaluation instruments, core strength training is more effective than typical resistance training for alleviating chronic low back pain. [Conclusion] All of the core strength training strategies examined in this study assist in the alleviation of chronic low back pain; however, we recommend focusing on training the deep trunk muscles to alleviate chronic low back pain.

Model-oriented therapies of aphasic word production have been shown to be effective, with item-specific therapy effects being larger than generalisation effects for untrained items. However, it remains unclear whether semantic versus phonological therapy lead to differential effects, depending on type of lexical impairment. Functional imaging studies revealed that mainly left-hemisphere, perisylvian brain areas were involved in successful therapy-induced recovery of aphasic word production. However, the neural underpinnings for model-oriented therapy effects have not received much attention yet. We aimed at identifying brain areas indicating (1) general therapy effects using a naming task measured by functional magnetic resonance imaging (fMRI) in 14 patients before and after a 4-week naming therapy, which comprised increasing semantic and phonological cueing-hierarchies. We also intended to reveal differential effects (2) of training versus generalisation, (3) of therapy methods, and (4) of type of impairment as assessed by the connectionist Dell model. Training effects were stronger than generalisation effects, even though both were significant. Furthermore, significant impairment-specific therapy effects were observed for patients with phonological disorders (P-patients). (1) Left inferior frontal gyrus, pars opercularis (IFGoper), was a positive predictor of therapy gains while the right caudate was a negative predictor. Moreover, less activation decrease due to therapy in left-hemisphere temporo-parietal language areas was positively correlated with therapy gains. (2) Naming of trained compared to untrained words yielded less activation decrease in left superior temporal gyrus (STG) and precuneus, bilateral thalamus, and right caudate due to therapy. (3) Differential therapy effects could be detected in the right superior parietal lobule for the semantic method, and in regions involving bilateral anterior and mid cingulate, right precuneus, and left middle

Percutaneous nephrolithotomy (PCNL) is an integral component in the management of large volume renal stone disease either as monotherapy or in combination with shock wave lithotripsy. Stone disease in patients on chronic anticoagulation/antiplatelet therapy, however, poses a difficult scenario. Bleeding is a major concern for any patient undergoing PCNL. We retrospectively analyzed our series of patients with renal calculi who were on chronic anticoagulant therapy and who underwent PCNL. We reviewed the case records of patients undergoing PCNL during the period from January 2005 to December 2011. We analyzed the changes in preoperative and postoperative hemoglobin, serum creatinine, and clotting parameters, as well as intraoperative and postoperative bleeding and thromboembolic complications. During the 5-year study period, a total of 36 patients (30 males and 6 females) with a mean age of 46.33±9.96 years (range, 29-61 years) who were on chronic anticoagulant/antiplatelet therapy underwent PCNL for urolithiasis. The mean size of the stone was 6.40±1.98 cm(2) (range, 2.8-9 cm(2)). The mean operating time was 62.08±10.10 min. The bleeding was successfully managed in all patients and the anticoagulant/antiplatelet agents were restarted after an appropriate duration. The mean rise in serum creatinine at discharge was 0.05±0.03 mg/dl and the mean fall in serum hemoglobin was 1.63±0.77 g/dl. At 3 months after surgery, the stone-free rate was 100%. With careful preoperative care and regulation of anticoagulation/antiplatelet therapy and appropriate intraoperative management, PCNL can be performed safely and successfully in properly selected patients with renal calculi who are on chronic anticoagulant/antiplatelet therapy.

Summary Background Personal health records (PHRs) connected to a physician’s electronic health record system hold substantial promise for supporting and engaging patients with chronic disease. Objectives: To explore how U.S. health care organizations are currently utilizing PHRs for chronic disease populations. Methods A mixed methods study including semi-structured interviews and a questionnaire was conducted. A purposive sample was developed of health care organizations which were recognized as exemplars for PHRs and were high performers in national patient satisfaction surveys (H-CAHPS or CAHPS). Within each organization, participants were health IT leaders or those managing high-risk or chronic disease populations. Results Interviews were conducted with 30 informants and completed questionnaires were received from 16 organizations (84% response rate). Most PHRs allowed patients to access health records and educational material, message their provider, renew prescriptions and request appointments. Patient generated data was increasingly being sought and combined with messaging, resulted in greater understanding of patient health and functioning outside of the clinic visit. However for chronic disease populations, there was little targeted involvement in PHR design and few tools to help interpret and manage their conditions beyond those offered for all. The PHR was largely uncoupled from high risk population management interventions and no clear framework for future PHR development emerged. Conclusion This technology is currently underutilized and represents a major opportunity given the potential benefits of patient engagement and shared decision making. A coherent patient-centric PHR design and evaluation strategy is required to realize its potential and maximize this natural hub for multidisciplinary care co-ordination. PMID:25024758

Chronic kidney disease (CKD) is a comorbid condition that affects, based on recent estimates, between 47% and 54% of patients with gouty arthritis. However, data from randomized controlled trials in patients with gouty arthritis and CKD are limited, and current gouty arthritis treatment guidelines do not address the challenges associated with managing this patient population. Nonsteroidal anti-inflammatory drugs and colchicine are recommended first-line treatments for acute gouty arthritis attacks. However, in patients with CKD, nonsteroidal anti-inflammatory drugs are not recommended because their use can exacerbate or cause acute kidney injury. Also, colchicine toxicity is increased in patients with CKD, and dosage reduction is required based on level of kidney function. Allopurinol, febuxostat, and pegloticase are all effective treatments for controlling elevated uric acid levels after the treatment of an acute attack. However, in patients with CKD, required allopurinol dosage reductions may limit efficacy; pegloticase requires further investigation in this population, and febuxostat has not been studied in patients with creatinine clearance<30 mL/min. This article reviews the risks and benefits associated with currently available pharmacologic agents for the management of acute and chronic gouty arthritis including urate-lowering therapy in patients with CKD. Challenges specific to primary care providers are addressed, including guidance to help them decide when to collaborate with, or refer patients to, rheumatology and nephrology specialists based on the severity of gout and CKD.

Study Objective: To investigate the structural changes in patients with chronic primary insomnia and the relationships with clinical features of insomnia. Design: Statistical parametric mapping 8-based voxel-based morphometry was used to identify differences in regional gray and white matter between patients with chronic primary insomnia and normal controls. Setting: University hospital. Patients and Participants: Twenty-seven patients and 27 age/sex-matched controls. Interventions: Regional differences were compared using two-sample t-tests with age, sex, and intracranial volume as covariates. Measurements and Results: The patients were a mean age of 52.3 y and had a mean history of insomnia of 7.6 y. Patients displayed cognitive deficits in attention, frontal/executive function, and nonverbal memory. Patients also displayed significantly reduced gray matter concentrations (GMCs) in dorsolateral prefrontal and pericentral cortices, superior temporal gyrus, and cerebellum and decreased gray matter volumes in medial frontal and middle temporal gyri compared with control patients with the cluster threshold ≥ 50 voxels at the level of uncorrected P < 0.001. Negative correlations were found between GMC of the prefrontal cortex and insomnia severity and the wakefulness after sleep onset, and between GMC of pericentral cortex and sleep latencies. None of the findings continued to be significant after correction for multiple comparisons. Conclusions: We found gray matter deficits in multiple brain regions including bilateral frontal lobes in patients with psychophysiologic insomnia. Gray matter deficit of the pericentral and lateral temporal areas may be associated with the difficulties in sleep initiation and maintenance. It is still unclear whether gray matter reductions are a preexisting abnormality or a consequence of insomnia.

Younger patients (defined as patients younger than 50-55 years of age) represent a small group of newly diagnosed patients with chronic lymphocytic leukemia, accounting only for 10% to 20% of newly diagnosed cases. However, once these patients become symptomatic and require treatment, their life expectancy is significantly reduced. Therapeutic approaches for younger patients should be directed at improving survival by achieving a complete remission and, where possible, eradicating minimal residual disease. Chemoimmunotherapy combinations carry the highest response rates and are commonly offered to younger patients. Additional strategies that should be considered for younger patients include early referral for stem-cell transplantation and clinical trials of consolidation therapy to eliminate minimal residual disease.

Most asthmatic patients with moderate to severe disease can be satisfactorily managed with a combination of inhaled corticosteroids and beta(2)-agonists. However, there are perhaps 10% of the asthmatic population with persistent symptoms, impaired quality of life and excessive health-care utilization, despite this management regime. These patients often require frequent and even occasionally regular oral corticosteroid use. Chronic, severe asthma is a heterogeneous disease with distinct sub-phenotypes. A systematic diagnostic work-up may help to identify these distinct sub-phenotypes and this may help guide treatment and may even provide information about prognosis. Optimal treatment of chronic severe asthma should achieve the best possible asthma control and quality of life with the least dose of systemic corticosteroids. The choice and formulation of therapeutic agent is dictated by the severity of disease and includes conventional, immunosuppressive/immunomodulating and biologic therapies. Unfortunately, current asthma management guidelines offer little contribution to the care of the challenging patient with chronic severe asthma. This review article aims at summarizing the evidence regarding various therapeutic modalities for chronic severe asthma and also aims to provide a practical approach to diagnosis and management for the benefit of those who have a specific interest in this problematic condition.

In patients with chronic kidney disease the alterations of the endocrine system may arise from several causes. The kidney is the site of degradation as well as synthesis of many different hormones. Moreover, a number of concomitant pathological conditions such as inflammation, metabolic acidosis and malnutrition may participate in the pathogenesis of endocrine abnormalities in this group of patients. The most pronounced endocrine abnormalities in patients with chronic kidney disease are the deficiencies of: calcitriol, testosterone, insulin-like growth factor and, erythropoietin (EPO). Additionally accumulation of several hormones, such as: prolactin, growth hormone and insulin frequently also occur. The clinical consequences of the abovementioned endocrine abnormalities are among others: anemia, infertility and bone diseases.

Background: Decision-making about patients with critical condition transfer from Intensive Care Unit to the general wards be delegated to their families. The aim of the study was explaining the experiences of family caregiver's about care of chronic critically ill patient. Methods: This study was conducted with a qualitative content analysis using unstructured interview. Participants were selected purposively from May 2014 to May 2015 and data collection continued until data saturation. Analysis was based on conventional content analysis. Results: Participants’ experiences classified into three main categories as following: nonprofessional care, enhancing factors of care, and inhibiting factors of care. Conclusions: Finding of the current study showed different aspects of care. Care of chronic critically ill patients is a long-term process that affected by different factors. It seems that the exploration of caregivers needs and planning supportive interventions based on their needs improve the quality of care. PMID:28028426

Previous research on neuropsychological disturbances in first-episode and chronic schizophrenic patients has provided mixed results which can be partially attributed to methodological inconsistencies. For the present study, 70 schizophrenic patients (40 with chronic and 30 with first-episode schizophrenia) were compared to 30 healthy controls on a large battery of neuropsychological tests. Special attention was paid to potential confounds such as differences in psychopathology, age and educational level between the schizophrenic sub-samples. Healthy controls performed better than both first-episode and chronic patients in almost all cognitive domains (P < 0.01), while the patient samples did not differ in any of the tasks. Results were confirmed in a second series of analyses in which patient subgroups were equated for sociodemographic background variables. The present results confirm recent data collected in longitudinal studies, thus, lending further support for a neurodevelopmental model of schizophrenia. It is suggested that neuropsychological disturbances occur early in schizophrenia and do not worsen in the course beyond age-related decrement. Possible reasons why previous research has produced contradictory findings are discussed.

Aim To investigate the chemotactic accuracy of peripheral blood neutrophils from patients with chronic periodontitis compared with matched healthy controls, before and after non-surgical periodontal therapy. Material & Methods Neutrophils were isolated from patients and controls (n = 18) by density centrifugation. Using the Insall chamber and video microscopy, neutrophils were analysed for directional chemotaxis towards N-formyl-methionyl-leucyl-phenylalanine [fMLP (10 nM), or CXCL8 (200 ng/ml)]. Circular statistics were utilized for the analysis of cell movement. Results Prior to treatment, neutrophils from patients with chronic periodontitis had significantly reduced speed, velocity and chemotactic accuracy compared to healthy controls for both chemoattractants. Following periodontal treatment, patient neutrophils continued to display reduced speed in response to both chemoattractants. However, velocity and accuracy were normalized for the weak chemoattractant CXCL8 while they remained significantly reduced for fMLP. Conclusions Chronic periodontitis is associated with reduced neutrophil chemotaxis, and this is only partially restored by successful treatment. Dysfunctional neutrophil chemotaxis may predispose patients with periodontitis to their disease by increasing tissue transit times, thus exacerbating neutrophil-mediated collateral host tissue damage.

Chronic abdominal wounds lead to prolonged hospital stays. However, no data exist that describe the experience of persons living with a chronic abdominal wound. The aim of this qualitative study was to explore the experience of persons living with chronic abdominal wounds and elicit their expectations in health professionals. Narrative interviews were conducted with five women and four men. Using content analysis techniques, five categories with one to four subcategories emerged from the data. "Returning to everyday life without a wound" represents the main goal of the participants and is driven by their hope to achieve this outcome. "Everyday life with the wound" illustrates the reality of participants' lives, which is affected by suffering. "The patients' work" demonstrates the component that patients contribute to managing their wound. "The work of primary support persons" shows the importance of the work of people close to the patient. "The work of professionals" includes the expectations that patients have in their caregivers. Teamwork between professionals, patients and primary support persons seems to be an essential condition for the successful healing of an abdominal wound.

Findings considering conditioned pain modulation (CPM) in chronic back pain (CBP) are contradictory. This might be because many patients with CBP report pain in further areas of the body, and altered CPM might influence spatial extent of pain rather than CBP per se. Therefore, we compared CPM in patients with CBP with different pain extent. Patients with fibromyalgia syndrome (FMS), for whom CPM impairment is reported most consistently, were measured for comparison. Based on clinical evaluation and pain drawings, patients were categorized into chronic local back pain (CLP; n = 53), chronic widespread back pain (CWP; n = 32), and FMS (n = 92). Conditioned pain modulation was measured by the difference in pressure pain threshold (test stimuli) at the lower back before and after tonic heat pain (conditioning stimulus). We also measured psychosocial variables. Pressure pain threshold was significantly increased in CLP patients after tonic heat pain (P < 0.001) indicating induction of CPM. Conditioned pain modulation in CLP was significantly higher than that in CWP and FMS (P < 0.001), but CPM in CWP and FMS did not differ. Interestingly, a higher number of painful areas (0-10) were associated with lower CPM (r = 0.346, P = 0.001) in CBP but not in FMS (r = -0.013, P = 0.903). Anxiety and depression were more pronounced in FMS than in CLP or CWP (P values <0.01). Our findings suggest that CPM dysfunction is associated with CWP and not with FMS as suggested previously. FMS seems to differ from CWP without FMS by higher psychosocial burden. Moreover, patients with CBP should be stratified into CLP and CWP, and centrally acting treatments targeting endogenous pain inhibition seem to be more indicated the higher the pain extent.

Tissue accumulation of advanced glycation end products (AGE) is thought to contribute to the progression of cardiovascular disease (CVD). Skin autofluorescence, a non-invasive measure of AGE accumulation using autofluorescence of the skin under ultraviolet light, has been reported to be an independent predictor of mortality associated with CVD in Caucasian patients on chronic hemodialysis. The aim of this study was to assess the predictive value of skin autofluorescence on all-cause and cardiovascular mortality in non-Caucasian (Japanese) patients on chronic hemodialysis. Baseline skin autofluorescence was measured with an autofluorescence reader in 128 non-Caucasian (Japanese) patients on chronic hemodialysis. All-cause and cardiovascular mortality was monitored prospectively during a period of 6 years. During the follow-up period, 42 of the 128 patients died; 19 of those patients died of CVD. Skin autofluorescence did not have a significant effect on all-cause mortality. However, age, carotid artery intima-media thickness (IMT), serum albumin, high-sensitivity C-reactive protein (hsCRP), skin autofluorescence and pre-existing CVD were significantly correlated with cardiovascular mortality. Multivariate Cox regression analysis showed skin autofluorescence (adjusted hazard ratio [HR] 3.97; 95% confidence interval [CI]1.67-9.43), serum albumin (adjusted HR 0.05; 95% CI 0.01-0.32), and hsCRP (adjusted HR 1.55; 95% CI 1.18-2.05) to be independent predictors of cardiovascular mortality. The present study suggests that skin autofluorescence is an independent predictor of cardiovascular mortality in non-Caucasian (Japanese) patients on chronic hemodialysis.

Streptococcus pneumoniae plays an important role in causing acute exacerbations in patients with chronic respiratory disease. However, few data are available regarding pneumococcal persistence in adult patients with chronic respiratory diseases. Fifty pneumococci recovered from sputum samples (1995 to 2010) from 13 adult patients with ≥3 episodes of acute exacerbation or pneumonia, with the same serotype and pulsed-field gel electrophoresis (PFGE) pattern, were studied. Multilocus sequence typing (MLST) loci, penicillin-binding protein (PBP) genes (pbp2x, pbp1a, pbp2b), and the quinolone-resistant determining regions (QRDRs) of parC, parE, and gyrA were PCR amplified and sequenced. The average time between the first and last episode was 582 days (standard deviation [SD], ±362). All but two patients received multiple courses of β-lactam treatment, and all persistent strains were resistant to penicillin; however, the PBP sequences were stable over time apart from one variable nucleotide in pbp2x, observed among pneumococci isolated from three patients. In contrast, 7/11 patients treated with fluoroquinolones had fluoroquinolone-resistant pneumococci. In three patients, the initially fluoroquinolone-susceptible strain developed resistance after fluoroquinolone therapy, and in the remaining four patients, the persistent strain was fluoroquinolone resistant from the first episode. QRDR changes involved in fluoroquinolone resistance were frequently observed in persistent strains after fluoroquinolone treatment; however, the PBP sequences and MLST genotypes of these strains were stable over time.

Hand dermatitis (HD) is usually due to a combination of various interacting factors. It involves significant impairment of the quality of life with psychological and socioeconomic impact. A therapeutic education program in HD.was elaborated by 19 health professionals (dermatologists, occupational clinical physicians, nurses, psychologists, environmental medical advisor) with experience in therapeutic education or skills in HD, according to the recommendations of Haute Autorité de Santé. The program includes an individual medical consultation to perform educational diagnostic, two collective workshops and a medical evaluation consult. Two group workshops "the disease, irritant factors and its treatments" and "the experiences and feelings" were elaborated with learning objectives and educative tools. Different scores were proposed to evaluate the program and acquired skills. Therapeutic education is an efficient way to help patients to adopt skin protection measures essential to healing. We propose a guideline of therapeutic education in HD including skills and educative tools and intended for health professionals to serve as working basis.

To identify the target molecules of chronic inflammatory demyelinating polyneuropathy (CIDP), we used proteomic-based approach in the extracted proteins from porcine cauda equina. Two of 31 CIDP patients had markedly elevated serum autoantibodies against vinculin, a cell adhesion protein. Both of the patients with anti-vinculin antibodies had similar clinical manifestation, which are compatible with those of "typical" CIDP. Immunocytochemistry showed that vinculin was stained at the myelin sheath of the sciatic nerves by serum samples. Our results suggest that vinculin is a possible immunological target molecule in a subpopulation of typical CIDP patients.

The determination of the level of secretory IgA by a method of radial immunodiffusion after Mancini in the gastric juice of 48 patients with chronic gastritis in correlation with the status of the gastric mucosa, the level of acidification and the phase of exacerbation has shown diagnostic potentialities of the method. The highest IgA level was detected in patients with "rearrangement" gastritis and in patients with sharply suppressed gastric secretion. In marked atrophy of the gastric mucosa IgA secretion was significantly lowered. The period of remission was attended by a decrease in IgA secretion as compared with the phase of exacerbation.

Recent years have seen the emergence of noninvasive ventilation (NIV) as an important tool for management of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Several well conducted studies in the recent years have established its role in the initial, as well as later management of these patients. However, some grey areas remain. Moreover, data is emerging on the role of long term nocturnal NIV use in patients with very severe stable COPD. This review summarizes the evidence supporting the use of NIV in various stages of COPD, discuss the merits as well as demerits of this novel ventilatory strategy and highlight the grey areas in the current body of knowledge.

Chronic lymphocytic leukaemia is a common lymphoid malignancy with a variable clinical course. While some patients never require treatment or can be managed effectively with palliative chemotherapy, others experience early disease progression and death. The development of new prognostic markers has helped in the identification of patients with high risk disease, even among those diagnosed at early stage. Recent prospective trials have established chemo-immunotherapy combinations as the new standard of care for CLL patients requiring therapy. Unfortunately, patients whose tumour cells have certain genomic aberrations, such as a chromosome 17 deletion, have a disease that is frequently refractory to conventional therapy and should have their treatment tailored accordingly. Younger patients with high risk disease should be referred for allogeneic haematopoietic cell transplantation if they have an appropriate donor. For the remaining high risk patients, a number of new compounds are emerging, which could lead to further improvement in their outcome.

Metformin therapy is limited in patients with chronic kidney disease (CKD) due to the potential risk of lactic acidosis. This open-label observational study investigated metformin and lactate concentrations in patients with CKD (n = 22; creatinine clearances 15-40 ml/min) and in two dialysed patients. Patients were prescribed a range of metformin doses (250-2000 mg daily) and metformin concentrations were compared with data from healthy subjects (scaled to 1500 mg twice daily). A subset of patients (n = 7) was controlled on low doses of metformin (250 or 500 mg daily). No correlation between metformin and lactate concentrations was observed. Three patients had high lactate concentrations (>2.7 mmol/l) and two had high metformin concentrations (3-5 mg/l), but none had any symptoms of lactic acidosis. Reducing metformin dosage and monitoring metformin concentrations will allow the safe use of metformin in CKD, provided that renal function is stable.
Protein and calorie malnutrition have been encountered more frequently than expected in the hemodialysis patients. Intradialytic parenteral nutrition (IDPN) has been documented to improve nutritional status in hemodialysis patients in both acute and chronic settings (Henrich, 1996). The aim of this study was to support the usage of IDPN in our malnourished hemodialysis patients. Serum concentration of albumin is one of the main indicators of mortality in the dialysis population. The serum albumin concentration for six out of eight of our hemodialysis (HD) patients receiving IDPN increased significantly. There was a mean increase of 7.0 g/L of plasma albumin for the eight patients assessed. These results demonstrate that IDPN is an effective nutritional intervention for malnourished hemodialysis patients.

Stem cell therapy (SCT) has been proposed for the treatment of neurological disorders. Although there is insufficient clinical evidence to support its efficacy, unproven SCTs are being performed worldwide. In this study, we investigated the perspectives and expectations of chronic ischemic stroke patients and physicians about SCTs. A total of 250 chronic ischemic stroke patients were interviewed at 4 hospitals. Structured open and closed questions about SCT for chronic stroke were asked by trained interviewers using the conventional in-person method. In addition, 250 stroke-related physicians were randomly interviewed via an e-mail questionnaire. Of the 250 patients (mean 63 years, 70% male), 121 (46%) responded that they wanted to receive SCT in spite of its unknown side effects. Around 60% of the patients anticipated physical, emotional, and psychological improvement after SCT, and 158 (63%) believed that SCT might prevent strokes. However, physicians had much lower expectations about the effectiveness of SCTs, which was not in line with patient expectations. Multivariate analysis revealed that the male gender [odds ratio (OR): 2.00, 95% confidence interval (CI): 1.10–3.64], longer disease duration (OR: 1.01, 95% CI: 1.00–1.02), higher modified Rankin Scale score (OR: 1.30, 95% CI: 1.06–1.60), and familiarity with stem cells (OR: 1.86, 95% CI: 1.10–3.15) were independently associated with wanting SCT. The major source of information about SCT was television (68%), and the most reliable source was physicians (49%). Patients have unfounded expectations that SCT will improve their functioning. Considering our finding that the major source of information on stem cells is media channels, but not the physician, to decrease patients' inappropriate exposure, doctors should make more effort to educate patients using mass media with accurate information.

Purpose: Resting-state functional magnetic resonance imaging (fMRI) studies have demonstrated the disruptions of multiple brain networks in tinnitus patients. Nonetheless, several studies found no differences in network processing between tinnitus patients and healthy controls (HCs). Its neural bases are poorly understood. To identify aberrant brain network architecture involved in chronic tinnitus, we compared the resting-state fMRI (rs-fMRI) patterns of tinnitus patients and HCs. Materials and Methods: Chronic tinnitus patients (n = 24) with normal hearing thresholds and age-, sex-, education- and hearing threshold-matched HCs (n = 22) participated in the current study and underwent the rs-fMRI scanning. We used degree centrality (DC) to investigate functional connectivity (FC) strength of the whole-brain network and Granger causality to analyze effective connectivity in order to explore directional aspects involved in tinnitus. Results: Compared to HCs, we found significantly increased network centrality in bilateral superior frontal gyrus (SFG). Unidirectionally, the left SFG revealed increased effective connectivity to the left middle orbitofrontal cortex (OFC), left posterior lobe of cerebellum (PLC), left postcentral gyrus, and right middle occipital gyrus (MOG) while the right SFG exhibited enhanced effective connectivity to the right supplementary motor area (SMA). In addition, the effective connectivity from the bilateral SFG to the OFC and SMA showed positive correlations with tinnitus distress. Conclusions: Rs-fMRI provides a new and novel method for identifying aberrant brain network architecture. Chronic tinnitus patients have disrupted FC strength and causal connectivity mostly in non-auditory regions, especially the prefrontal cortex (PFC). The current findings will provide a new perspective for understanding the neuropathophysiological mechanisms in chronic tinnitus. PMID:27458377

Carnitine metabolism was studied in 79 patients with chronic liver disease, including 22 patients with noncirrhotic liver disease and 57 patients with different types of cirrhosis (22 patients with hepatitis B- or C-associated cirrhosis, 15 patients with alcohol-induced cirrhosis, 15 patients with primary biliary cirrhosis [PBC], and 5 patients with cryptogenic cirrhosis), and compared with 28 control subjects. In comparison with control subjects, patients with noncirrhotic liver disease showed no change in the plasma carnitine pool, whereas patients with cirrhosis had a 29% increase in the long-chain acylcarnitine concentration. Analysis of subgroups of patients with cirrhosis showed that patients with alcohol-induced cirrhosis had an increase in the total plasma carnitine concentration (67.8 +/- 29.5 vs. 55.2 +/- 9.9 micromol/L in control subjects), resulting from increases in both the short-chain and long-chain acylcarnitine concentration. In this group of patients, the acylcarnitine concentrations showed a close correlation with the total carnitine concentration, and the total carnitine concentration with the serum bilirubin concentration. Urinary excretion of carnitine was not different between patients with noncirrhotic or cirrhotic liver disease and control patients. However, patients with PBC showed an increased urinary excretion of total carnitine (52.5 +/- 40.0 vs. 28.0 +/- 16.7 micromol carnitine/mmol creatinine), resulting from an increase in the fractional excretion of both free carnitine and short-chain acylcarnitine. The current studies show that patients with cirrhosis are normally not carnitine deficient. Patients with alcohol-induced cirrhosis have increased plasma carnitine concentrations, which may result from increased carnitine biosynthesis because of increased skeletal muscle protein turnover. The increase in the fractional carnitine excretion in patients with primary biliary cirrhosis may result from competition of bile acids and

A 47-year-old woman presented with a history of vague abdominal pain for several years, which worsened over the past 2 months, with pain more prominent in the right upper quadrant. She also had a history of peptic ulcer disease. The ultrasound scan of right upper quadrant revealed normal gallbladder and oesophagogastroduodenoscopy was unremarkable. A (99m)technetium labelled hepato iminodiacetic acid (HIDA) scan with cholecystokinin provocation demonstrated a decreased gallbladder ejection fraction (EF) of 32%. On this basis, the patient was diagnosed with biliary dyskinesia and underwent an elective laparoscopic cholecystectomy. Histopathological analysis revealed chronic cholecystitis with Cystoisospora belli identified in the gallbladder wall. Cystoisospora has been identified to cause an opportunistic acalculous cholecystitis among immunocompromised hosts, especially those with AIDS. This is the first case report of chronic cholecystitis due to C. belli in an immunocompetent patient.
The population of patients with chronic kidney disease is aging, and approximately 50% of those starting renal replacement therapy are older than 65 years. Aging poses challenges to maintaining the nutritional status of these patients. As patients get older, purchasing and preparing food may become difficult if the patient is not supported by relatives or social workers. In addition, appetite may decrease as a result of depression. Furthermore, intercurrent illnesses may become more frequent, leading to changes in nutrient requirements. Mobility and cognitive function often decline in elderly patients and the combination of these factors may result in malnutrition. Since malnutrition has been demonstrated to impact on survival in dialysis patients of all ages, appropriate attention to nutritional status and its management is essential in the elderly patient, both in the predialysis phase and on dialysis. This article reviews the issues associated with the maintenance of good nutrition in elderly patients and describes the potential causes of malnutrition. It also reviews the nutrient requirements of older dialysis patients (which differ somewhat from those of younger patients) as well as the assessment of their nutritional status. Finally, recommendations for the management of nutrition in the elderly patient are discussed.

Pulmonary hypertension (PH) is a common complication of chronic pulmonary diseases, especially in advanced disease, and is associated with greater mortality and worse clinical course. Patients with symptoms that exceed those expected by their pulmonary disease should be further evaluated by echocardiography. Confirmatory right heart catheterization is indicated in those conditions where the results of the hemodynamic assessment will determine treatment options. The treatment of choice for patients who are hypoxemic and have pulmonary hypertension associated with chronic lung disease is long-term oxygen therapy. Conventional vasodilators or drugs approved for pulmonary arterial hypertension are not recommended in patients with mild-to-moderate PH because they may impair gas exchange and because there is a lack of evidence supporting their efficacy. Patients with severe PH should be considered for referral to a center with expertise in PH and lung diseases. Ideally, these patients should be included in randomized controlled trials to determine which patients are more likely to derive benefit and which therapies are most likely to be successful.

Chronic rhinosinusitis (CRS) is a common inflammatory condition of nasal and paranasal sinus mucosa. Although pathogenic bacteria were postulated as main etiological factor responsible for most cases of CRS, the involvement of molds was recently proved in some cases. The aim of the study was to conduct mycological analysis of material obtained from patients operated on due to chronic sinusitis. The study included 107 patients, 45 women and 62 men. During the surgery, a fragment of mucosa from the region of the ethmoid bulla was obtained as microbiological characteristics of this material closely resemble those of sinus mucosa. In addition, maxillary sinus lavage was obtained. The control group comprised patients without chronic sinusitis. The dithiothreitol solution method was used for the lavage examination. The tissue material (mucosal fragment from the region of the ethmoid bulla) was incubated in 2% liquid Sabouraud medium for 24 h. The material was inoculated onto culture media. The presence of molds was detected in 67% of examined samples. Overall, 41 species belonging to 12 genera were isolated. The most frequently detected genera included Penicillium spp. (46%) and Aspergillus spp. (16%). In addition, Cladosporium spp. (11%), Fusarium spp. (7%), Acremonium spp. (4%), Eurotium spp. (4%), Alternaria spp. (2%), Chaetomium spp. (1%), Geotrichum spp. (1%), Verticillium spp. (1%), Rhizopus spp. (1%), and some unidentified colonies (5%) were isolated. Penicillium crustosum, Penicillium citrinum, Aspergillus niger, Cladosporium cladosporioides, and Fusarium verticillioides were the most prevalent species.

The aim of this study was to compare the frequency of upper gastrointestinal (GI) complaints and complications between chronic rheumatic patients who are most often non-steroidal anti-inflammatory drugs (NSAIDs) users and patients with other chronic conditions. In this comparison we took into account known risk factors for upper GI disease. To achieve the study aims we performed a combined cross-sectional and retrospective study. We therefore interviewed by means of a standard questionnaire, an index and a reference group, about current upper GI complaints and previous complications. The former group comprises 578 outpatients of the Department of Rheumatology, the latter of 531 outpatients of the Departments of Internal Medicine, Pulmonology, and Cardiology. Although the number of patients in the index group being chronically treated with NSAIDs was very high (62% versus 9% in the reference group: P < 0.00001), no between-group differences were found for the frequency of several current upper gastrointestinal complaints or for the number of upper gastrointestinal investigations ever performed (35% and 37%: NS) or for the use of gastric drugs (14% and 10%: NS). Risk factors for upper GI complaints were not related to NSAID use but with the use of prednisolone, history of duodenal ulcer disease, family history of peptic ulcer disease and female sex. For peptic ulcer disease, bleeding, and gastric surgery, the only difference between the index and reference groups concerned the frequency of gastric ulcers (6.7% and 2.8%: P < 0.005), which was highest in patients with rheumatoid arthritis. Upper GI bleeding had more often been present in male seropositive rheumatoid arthritis patients (13.2% [corrected] and 4.5%: P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
Patient empowerment is a patient-centered approach to care in which healthcare providers nurture patients' innate abilities to self-manage and incorporate patient goals for therapy into the overall management plan. Standard care of chronic myeloid leukemia (CML) requires lifelong medication with oral therapy and regular follow-up. The success of CML treatment, therefore, depends on a high degree of patient involvement and motivation, as well as strong collaboration between patients and healthcare providers. Oncology nurses can support patients with CML from the time of diagnosis to the end of treatment to ensure they maintain high levels of involvement in their care. At the author's center, patients who most actively collaborate with their physicians in treatment decisions take personal responsibility for the quality of their care and show good adherence to treatment. In the current article, the author discusses the potential effect of patient response to cancer diagnosis on clinical outlook and describes strategies in place at the cancer center to ensure that patients diagnosed with CML have the best chance at keeping their cancer under control.

The objectives of this review were (1) to review recent literature on the rates, risk factors, and outcomes of infections in patients who had chronic kidney disease (CKD) and did or did not require renal replacement therapy; (2) to review literature on the efficacy and use of selected vaccines for patients with CKD; and (3) to outline a research framework for examining key issues regarding infections in patients with CKD. Infection-related hospitalizations contribute substantially to excess morbidity and mortality in patients with ESRD, and infection is the second leading cause of death in this population. Patients who have CKD and do not require renal replacement therapy seem to be at higher risk for infection compared with patients without CKD; however, data about patients who have CKD and do not require dialysis therapy are very limited. Numerous factors potentially predispose patients with CKD to infection: advanced age, presence of coexisting illnesses, vaccine hyporesponsiveness, immunosuppressive therapy, uremia, dialysis access, and the dialysis procedure. Targeted vaccination seems to have variable efficacy in the setting of CKD and is generally underused in this population. In conclusion, infection is a primary issue when caring for patients who receive maintenance dialysis. Very limited data exist about the rates, risk factors, and outcomes of infection in patients who have CKD and do not require dialysis. Future research is needed to delineate accurately the epidemiology of infections in these populations and to develop effective preventive strategies across the spectrum of CKD severity.

The complex network of etiological factors, signals and tissue responses involved in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) cannot be successfully targeted by a single therapeutic agent. Multimodal approaches to the therapy of CP/CPPS have been and are currently being tested, as in the frame of complex diagnostic-therapeutic phenotypic approaches such as the urinary, psychosocial, organ-specific, infection, neurological and muscle tenderness (UPOINTS) system. In this study, the effect of combination therapy on 914 patients diagnosed, phenotyped and treated in a single specialized prostatitis clinic was analyzed. Patients received α-blockers, Serenoa repens (S. repens) extracts combined or not with supplements (lycopene and selenium) and, in the presence of documented or highly suspected infection, antibacterial agents. Combination treatment induced marked and significant improvements of National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) prostatitis symptom scores, International Index of Erectile Function (IIEF) sexual dysfunction scores, urinary peak flow rates and bladder voiding efficiency. These improvements, assessed after a 6-month course of therapy, were sustained throughout a follow-up period of 18 months. A clinically appreciable reduction of ≥6 points of the total NIH-CPSI score was achieved in 77.5% of patients subjected to combination therapy for a period of 6 months. When the patients were divided in two cohorts, depending on the diagnosis of CP/CPPS [inflammatory (IIIa) vs. non-inflammatory (IIIb) subtypes], significant improvements of all signs and symptoms of the syndrome were observed in both cohorts at the end of therapy. Intergroup comparison showed that patients affected by the IIIa sub-category of CP/CPPS showed more severe signs and symptoms (NIH-CPSI total, pain and quality of life impact scores, and Qmax) at baseline when compared with IIIb patients. However, the improvement of symptoms after

The chronic obstructive pulmonary disease has become a disease of public health importance. Among the various risk factors, smoking remains the main culprit. In addition to airway obstruction, the presence of intrinsic positive end expiratory pressure, respiratory muscle dysfunction contributes to the symptoms of the patient. Perioperative management of these patients includes identification of modifiable risk factors and their optimisation. Use of regional anaesthesia alone or in combination with general anaesthesia improves pulmonary functions and reduces the incidence of post-operative pulmonary complications. PMID:26556916

Wandering spleen or splenoptosis is an uncommon entity and often an asymptomatic finding of acute abdomen in the emergency department. A high index of suspicion for splenic torsion is required, particularly in patients with known splenomegaly, as this condition could potentially lead to splenic infarction. Recognition of this condition can help avoid potential confusion with acute abdomen of other aetiologies. Herein, we present a unique case of wandering spleen with chronic torsion, which, to the best of our knowledge, has never been described in an elderly patient with haemoglobin H thalassaemia. We also review the literature for the aetiology and pathogenesis of wandering spleen, and discuss the relevant diagnostic modalities and treatment options.

Chronic hepatitis B is a common disease and approximately 20% of infected patients with compensated cirrhosis will decompensate over 5 years. If untreated, the survival of decompensated cirrhosis is poor (15% at 5 years). The extent of hepatitis B virus (HBV) replication, as assessed by serum HBV-DNA level, is a strong predictor of the risk of disease progression and hepatocellular carcinoma. This provides a rationale for antiviral therapy to arrest progression of liver disease. Lamivudine is a pyrimidine analogue that inhibits HBV-DNA reverse transcriptase. It decreases HBV replication, normalises alanine aminotransferase levels and reduces hepatic inflammation and fibrosis in patients with chronic hepatitis B. This article will focus on the use of lamivudine in patients with HBV-cirrhosis. In patients with compensated HBV-cirrhosis, a randomised, placebo-controlled trial has shown that lamivudine significantly reduced the rate of disease progression and hepatocellular carcinoma development over a 3-year period. In patients with decompensated cirrhosis, treatment with lamivudine can produce spectacular improvements of liver function, but the improvement is slow and a clinical benefit is usually not observed until after at least 3-6 months of treatment. A major drawback of lamivudine treatment is the development of resistance, observed in 15-20% of patients after 1 year and up to 70% after 5 years of continued treatment. Thus, patients with HBV-cirrhosis treated with lamivudine should have regular monitoring of serum HBV-DNA levels and prompt institution of additional antiviral therapy if viral breakthrough is observed. Adefovir, tenofovir and entecavir have demonstrated efficacy in patients with lamivudine resistance. In patients with decompensated cirrhosis, in whom the development of resistance can be fatal, combination therapy (such as lamivudine plus adefovir) may prove more effective than monotherapy and this issue needs further study.

The cases of 76 patients with chronic radiation dermatitis resulting from low-dose ionizing radiation for benign disease were reviewed retrospectively for risk factors leading to the development of neoplasia. The patients were studied with respect to original hair color, eye color, sun reactive skin type, benign disease treated, area treated, age at treatment, and age at development of first skin cancer. Analysis of data showed 37% of patients had sun-reactive skin type I, 27% had type II, and 36% had type III. Types IV through VI were not represented. There appeared to be an overrepresentation of types I and II. Increased melanin pigmentation may therefore be either directly or indirectly protective against the development of skin cancers in patients who have received low-dose superficial ionizing radiation for benign disease. The sun-reactive skin type of patients with chronic radiation dermatitis may be used as a predictor of skin cancer risk when the total dose of ionizing radiation is not known.

Chronic obstructive pulmonary disease (COPD) is a debilitating disease characterized by inflammation-induced airflow limitation and parenchymal destruction. In addition to pulmonary manifestations, patients with COPD develop systemic problems, including skeletal muscle and other organ-specific dysfunctions, nutritional abnormalities, weight loss, and adverse psychological responses. Patients with COPD often complain of dyspnea on exertion, reduced exercise capacity, and develop a progressive decline in lung function with increasing age. These symptoms have been attributed to increases in the work of breathing and in impairments in gas exchange that result from airflow limitation and dynamic hyperinflation. However, there is mounting evidence to suggest that skeletal muscle dysfunction, independent of lung function, contributes significantly to reduced exercise capacity and poor quality of life in these patients. Limb and ventilatory skeletal muscle dysfunction in COPD patients has been attributed to a myriad of factors, including the presence of low grade systemic inflammatory processes, nutritional depletion, corticosteroid medications, chronic inactivity, age, hypoxemia, smoking, oxidative and nitrosative stresses, protein degradation and changes in vascular density. This review briefly summarizes the contribution of these factors to overall skeletal muscle dysfunction in patients with COPD, with particular attention paid to the latest advances in the field.

Altered systemic iron metabolism is a key element of uremia, and functional iron deficiency mainly related to subclinical inflammation makes it difficult to maintain proper control of anemia in chronic hemodialysis patients (CHD). In the last decade, the hepatic hormone hepcidin has been progressively recognized as the master regulator of circulating iron levels through the modulation of cellular iron fluxes in response to iron stores, as well as to erythroid and inflammatory stimuli. Hepcidin is cleared by the kidney and progression of renal disease has been associated to increased serum hepcidin levels. This, in turn, reduces iron availability for erythropoiesis, suggesting anti-hepcidin strategies for improving anemia control. Moreover, hepcidin has been recently implicated in the pathogenesis of long-term complications of dialysis, like accelerated atherosclerosis. Initial studies almost invariably reported a sustained increase of serum hepcidin in chronic hemodialysis patients. Noteworthy, such studies included relatively few patients and controls that were poorly matched for major determinants of serum hepcidin at population level, i.e., age and gender. More recent data based on accurately matched larger series challenge the view that hepcidin is intrinsically increased in hemodialysis patients, showing a marked inter- and intra-individual variability of hormone levels. Here we take a critical look to the data published so far on hepcidin levels in CHD, analyze the reasons underlying the discrepancies in available studies and the hepcidin variability in CHD, and point out the need for further studies in large series of well-characterized CHD patients and controls.

Semantic errors are commonly found in semantic dementia (SD) and some forms of stroke aphasia and provide insights into semantic processing and speech production. Low error rates are found in standard picture naming tasks in normal controls. In order to increase error rates and thus provide an experimental model of aphasic performance, this study…

Background Pulmonary hypertension (PH) is a common finding in patients with chronic fibrosing idiopathic interstitial pneumonias (IIP). Little is known about the response to pulmonary vasodilator therapy in this patient population. COMPERA is an international registry that prospectively captures data from patients with various forms of PH receiving pulmonary vasodilator therapies. Methods We retrieved data from COMPERA to compare patient characteristics, treatment patterns, response to therapy and survival in newly diagnosed patients with idiopathic pulmonary arterial hypertension (IPAH) and PH associated with IIP (PH-IIP). Results Compared to patients with IPAH (n = 798), patients with PH-IIP (n = 151) were older and predominantly males. Patients with PH-IIP were treated predominantly with phosphodiesterase-5 inhibitors (88% at entry, 87% after 1 year). From baseline to the first follow-up visit, the median improvement in 6MWD was 30 m in patients with IPAH and 24.5 m in patients with PH-IIP (p = 0.457 for the difference between both groups). Improvements in NYHA functional class were observed in 22.4% and 29.5% of these patients, respectively (p = 0.179 for the difference between both groups). Survival rates were significantly worse in PH-IIP than in IPAH (3-year survival 34.0 versus 68.6%; p<0.001). Total lung capacity, NYHA class IV, and mixed-venous oxygen saturation were independent predictors of survival in patients with PH-IIP. Conclusions Patients with PH-IIP have a dismal prognosis. Our results suggest that pulmonary vasodilator therapy may be associated with short-term functional improvement in some of these patients but it is unclear whether this treatment affects survival.

This study investigated the prevalence of Actinomyces spp. in shallow, deep and very deep pockets of patients with chronic periodontitis compared to healthy controls and correlated the results with clinical status. Twenty patients with chronic periodontitis and 15 healthy subjects were enrolled in this study. Clinical indices were recorded in a six-point measurement per tooth. From each patient samples of supra and subgingival plaque were taken separately from teeth with shallow, deep and very deep pockets. Samples of supragingival plaque and sulcular microflora were collected from the healthy subjects. All the samples were cultivated on different media at 37̊C in an anaerobic atmosphere for 7 days. All the suspect colonies were identified using a rapid ID 32 A system (bioMèrieux) and MALDI-TOF-MS analysis using an Autoflex II Instrument (Bruker Daltonics) together with in house developed identification software and a reference spectra database. A total of 977 strains were identified as Actinomyces. Actinomyces naeslundii/oris/johnsonii (430 isolates) was the most prevalent species and was found in all patients and in almost all of the healthy subjects. Significant differences (p=0.003) between the groups were found for Actinomyces odontolyticus/meyeri and Actinomyces israelii which were associated with periodontitis patients. Actinomyces dentalis was found in higher percentage (p=0.015) in the periodontitis group. Actinomyces gerencseriae and Actinomyces massiliensis were significantly more often found supragingivally than subgingivally (p=0.004, p=0.022, respectively) in the periodontitis group. Whether some Actinomyces species, definitely important plaque formers, are actively involved in the pathogenicity of chronic periodontitis needs further investigation.

Chronic hepatitis C (HCV) infection is a serious problem all over the world and has a special importance in Egypt, where the prevalence of infection is 14.7% of population. In males, HCV is associated with sexual dysfunction and changes in the semen parameters. This study aimed at estimation of a panel of the most important related hormones in the serum of patients and illustration of their correlation to the routine laboratory investigations. The four studied hormones showed alteration in the patients in comparison with the controls. While androstenedione, prolactin and testosterone were significantly increased in patients, dehydroepiandrosterone sulphate was decreased. These changes in the hormones were not related to the liver functions, pathological grade or even viral load. We hypothesised a model of how HCV can induce these hormonal changes and recommended to add these hormones to the follow-up panel of male patients with HCV.

Introduction Chronic prostatitis is a widespread urological disease with a lengthy course and a propensity to frequent recurrences. Adequate response to anti–inflammatory therapy is lacking in a high percentage of patients, which causes them to seek medical advice from different doctors. Thus, the physicians are challenged to look for other reasons causing the pathological symptoms. Material and methods We have reviewed the patients with treatment–resistant chronic bacterial prostatitis (CBP) from the perspective of psychosomatic medicine. For the evaluation of primary mental status and treatment control we used standard approved questionnaires. All 337 CBP patients initially underwent therapy aimed at pathogen eradication. If psychopathological symptoms were evident and dominated over urological ones, the patients were referred to psychiatric evaluation and treatment. Results The frequency of concomitant psychosomatic disorders (PSD) in patients with CBP was 28.2% and neurotic disorders – 26.4%. Adequate multimodal anti–inflammatory therapy followed by a few sessions of psychotherapy decreased the manifestations of PSD in 30.5%, neurotic disorders in 51.7%, and premature ejaculation in 60.5% of patients with CBP. The addition of pharmacotherapy to psychotherapy is effective in treatment–resistant cases. However, after multimodal treatment, 31.5% of pts. with PSD and 13.5% of pts. with neurotic disorders still remain treatment–resistant and required in–depth long–term psychiatric care. Conclusions A significant portion of CBP patients were diagnosed with neurotic, psychosomatic, and/or depressive disorders. Antibacterial and anti–inflammatory therapy, when followed by appropriate psychotherapy and pharmacotherapy, significantly decrease the manifestations of mental disorders in CBP patients.

Demyelinating neuropathies are typically characterized by physiological slowing of conduction velocity and pathologically by segmental loss of myelin and in some instances, evidence of remyelination. Clinically, patients with demyelinating neuropathy can be seen with inherited disorders (Charcot-Marie-Tooth disease) or acquired disorders, typically immune-mediated or inflammatory. The acquired disorders can be either acute or subacute as seen in the acute inflammatory demyelinating polyneuropathy (AIDP) form of Guillain-Barré syndrome or chronic progressive or relapsing disorders such as chronic inflammatory demyelinating polyneuropathy. It is important to develop a logical approach to diagnosing these disorders. This requires an understanding of the clinical, genetic, physiological, and pathological features of these neuropathies. Clinically, important features to consider are the temporal progression, degree of symmetry, and involvement of proximal as well as distal muscles. Genetically, recognizing the different inheritance patterns and age of onset allow for a coordinated approach to determining a specific genotype. Physiologically, besides nerve conduction slowing, other physiological hallmarks of demyelination include temporal dispersion of compound motor action potentials (CMAP) on proximal stimulation, conduction block, and distal CMAP duration prolongation with certain patterns of involvement pointing to specific disorders. This chapter focuses on these various aspects of the evaluation of patients with chronic acquired demyelinating neuropathies to develop a comprehensive and thoughtful diagnostic concept.

A wide array of benefits has been attributed to metformin. These include attenuation of abnormal glucose metabolism (diabetes treatment and prevention), weight neutrality or weight loss, improvement in the pathophysiologic components of metabolic syndrome (insulin resistance, subclinical inflammation, and endothelial dysfunction), lipid-lowering properties, cardiovascular protection, and antineoplastic potential. Metformin itself is not a nephrotoxic drug. Initially appointed as the safest hypoglycemic agent in chronic kidney disease, its use has been limited in these patients because of the perceived risk of lactic acidosis. A fear perpetuated by numerous case reports in which it is implicated. Current guidelines stipulate that it must be used with caution in estimated glomerular filtration rates (eGFRs) of less than 60 mL/minute and not at all in eGFRs of less than 30 mL/minute. Identified risk factors for metformin-associated lactic acidosis include acute kidney injury, hypoxemia, sepsis, alcohol abuse, liver failure, myocardial infarction, and shock. Treatment may include supportive care and dialysis techniques. On the other hand, it is likely that the use of metformin would be beneficial in many with chronic kidney disease according to the advantages associated with attenuation of metabolic syndrome and cardiovascular protection. The reality of severe metformin-induced lactic acidosis in the absence of chronic renal impairment raises the question of limitation of its use in these patients.

A study group of 30 individuals was randomly chosen from 1,379 beneficiaries predicted to be at risk for health care complications at a large, Midwest, industrial company currently experiencing increased health care costs. All 30 individuals had one or more chronic illness, primarily diabetes, cardiovascular disease, or asthma. Through analysis of medical records, a self-reporting health risk assessment survey, and personal contact with both patients and clinicians, each study individual was assessed as to whether his disease(s) was under control, the individual was compliant with his treatment protocol, and whether the supervising clinician was following nationally accepted standards of care. Fewer than 50% of the individuals in the study group had their chronic illness(es) under control. Those individuals whose treatment adhered to national guidelines were significantly more likely to have their disease under control (p < 0.001). For this study, patient compliance was high and unrelated to whether their disease was under control. Behavioral (external) barriers were most often cited as the reason a clinical practitioner did not follow the appropriate national standard of care. Most clinicians were aware of and familiar with the guidelines; a few either did not agree with or misunderstood the guidelines. The results of this study suggest that changing clinical practice behaviors to better ensure compliance to national standards of care may make a substantial difference in chronic disease control.

Abstract and Introduction Abstract Constipation is a highly prevalent and bothersome disorder that negatively affects patients' social and professional lives and imposes a heavy economic burden on patients and society. Most patients with chronic constipation are evaluated and treated in the primary care setting. Primary care clinicians often underestimate how much they can accomplish in the evaluation of a patient with constipation before they make a referral. There are numerous steps that primary care clinicians can take to address these issues and maximize the benefits of the referral process, including understanding key elements of an effective diagnostic work-up, familiarizing themselves with the utility of various diagnostic tests of colonic and anorectal function, implementing strategies/instruments to optimally communicate what they are striving to achieve through the referral process (eg, via a referral form), and developing a network of long-term working relationships with local gastroenterologists. Introduction Constipation is a highly prevalent disorder that affects approximately 12% to 19% of North Americans – estimates vary widely depending on study design and methodology.[1–6] For many persons, constipation is a chronic problem, lasting from several months to several years. The multiple symptoms of chronic constipation encompass much more than reduced stool frequency; many patients report straining, feelings of incomplete evacuation, abdominal pain/discomfort, bloating, hard and/or small stools, or a need for digital manipulation to enable defecation.[5,7–12] For research purposes (eg, enrolling patients into clinical trials), the Rome II diagnostic criteria for constipation are generally used (Table 1).[2,13] Chronic constipation leads to decreased quality of life. The general well-being of patients with this disorder is lower than that of comparable normal populations,[14,15] and symptom severity has a negative correlation with perceived

Background The etiology of chronic urticaria (CU) remains unknown in most patients. Possible causes in some cases include food, but the role of allergy to food antigens in patients with CU remains controversial. Objective The aim of this study was to evaluate the association between food allergy and CU. Methods Korean patients with CU were assessed for a previous history of food allergy that caused symptoms of CU. Blood samples were taken from 350 patients to measure food allergen-specific IgE. Based on history and laboratory results, open oral food challenge (OFC) tests were performed. Results Of 350 participants, 46 (13.1%) claimed to have experienced previous food hypersensitivity. Pork (n=16) was the main food mentioned, followed by beef (n=7), shrimp (n=6), and mackerel (n=6). We found that 73 participants (20.9%) had elevated levels of food-specific IgE, with pork (n=30), wheat (n=25), and beef (n=23) being the most common. However, when the open OFC tests were conducted in 102 participants with self-reported food hypersensitivity or raised levels of food-specific IgE, only four participants showed a positive reaction to pork (n=3) or crab (n=1). Conclusion Although some participants claimed to have a history of CU related to food intake, when an open OFC test was conducted, few of them had positive results. We therefore conclude that food allergy is an uncommon cause of chronic CU. PMID:27746634

Within the European Union-sponsored project DIABCARD, the core of a chip-card-based medical information system for patients with chronic diseases, exemplified on diabetes mellitus, has been developed. The long-term goal of the project is to improve the medical record and the quality of care for patients with chronic diseases. The basic idea is to have a portable electronic medical record on a smart card. This will improve the communication between the different healthcare personnel and between different institutions and, at the same time, promote shared care. The DIABCARD chip-card-based medical information system will offer controlled access to the necessary and up-to-date patient record to everyone involved in the patient's treatment, and it will help reduce the constantly rising healthcare expenditure. The system first was implemented in a small version. The system architecture contains hardware, software, and orgware. It considers especially the memory of the chip card, the processor, the data structure, security functions, the operating system on the chip card, the interface between the chip card and the application, and various application areas. The DIABCARD dataset was defined via an information model, which describes the different communication processes, via acknowledged diabetes datasets and medical scenarios. It includes, among others, emergency data, data for quality assurance, and data for blood glucose self-monitoring. The first prototype has been developed, and a pilot was run for 3 months.

Flying is the most important way of travelling in the continually growing international tourism. Number of passengers and those with preexisting diseases, mainly with cardiopulmonary problems, is increasing over years. One of the main tasks of the pre-travel advice is to assess tolerance to hypoxia of the traveler, and specify the necessity, as well as the type and volume of supplementary oxygen therapy. It is indispensable to know the cabin-environment and impact of that on the travelers' health. Travel medicine specialist has to be aware of the examinations which provide information for the appropriate decision on the fit-to-fly condition of the patient. The physician who prepares the patient with chronic obstructive pulmonary disease for repatriation by regular flight and the escorting doctor have to be fully aware of the possibilities, modalities, advantages and contraindications of the on-board oxygen supply and therapy. In this review, the authors give a summary of literature data, outline the tools of in-flight oxygen therapy as well as discuss possibilities for the preflight assessment of patients' condition including blood gas parameters required for safe air travel, as recommended in international medical literature. The preparation process for repatriation of patients with chronic obstructive pulmonary disease is also discussed.

Affective instability, conceptualized as fluctuations in mood over time, has been related to ill-health and psychopathology. In this study, we examined the role of affective instability on daily pain outcomes in 70 patients with chronic pain (Mage = 49.7 years; 46 females) using an end-of-day diary. During a baseline phase, patients completed self-reported questionnaires of pain severity, pain duration, disability, depression, and anxiety. During a subsequent diary phase, patients filled out an electronic end-of-day diary over 14 consecutive days assessing daily levels of pain severity, disability, cognitive complaints, negative affect (NA) and positive affect. Affective instability was operationalized as the mean square of successive differences in daily mood (separately for NA and positive affect), which takes into account the size of affective changes over consecutive days. Results indicated that NA instability was positively associated with daily disability, beyond the effects of daily pain severity. Furthermore, NA instability moderated the relationship between daily pain severity and daily disability and the relationship between daily pain severity and daily cognitive complaints. Positive affect instability, however, showed to be unrelated to all outcomes. Current findings extend previous results and reveal the putative role of affective instability on pain-related outcomes and may yield important clinical implications. Indeed, they suggest that targeting NA instability by improving emotion regulation skills may be a strategy to diminish disability and cognitive complaints in patients with chronic pain.

To assess whether NLR pyrin domain-containing protein 3 (NLRP3) inflammasome, a multiprotein complex that mediates the activation of caspase-1 (CASP-1) and pro-inflammatory cytokines IL-18 and IL-1β, could be involved in the chronic inflammatory state observed in chronic kidney disease patients undergoing hemodialysis treatment (CKD-HD), we employed several biomolecular techniques including RT-PCR, western blot, FACS analysis, confocal microscopy and microarray. Interestingly, peripheral blood mononuclear cells from 15 CKD-HD patients showed higher mRNA levels of NLRP3, CASP-1, ASC, IL-1β, IL-18 and P2X7receptor compared to 15 healthy subjects. Western blotting analysis confirmed the above results. In particular, active forms of CASP-1, IL1-β and IL-18 resulted significantly up-regulated in CKD-HD versus controls. Additionally, elevated mitochondrial ROS level, colocalization of NLRP3/ASC/mitochondria in peripheral blood mononuclear cells from CKD-HD patients and down-regulation of CASP-1, IL1-β and IL-18 protein levels in immune-cells of CKD-HD patients stimulated with LPS/ATP in presence of mitoTEMPO, inhibitor of mitochondrial ROS production, suggested a possible role of this organelle in the aforementioned CKD-associated inflammasome activation. Then, microarray analysis confirmed, in an independent microarray study cohort, that NLRP3 and CASP-1, along with other inflammasome-related genes, were up-regulated in 17 CKD-HD patients and they were able to clearly discriminate these patients from 5 healthy subjects. All together these data showed, for the first time, that NLRP3 inflammasome was activated in uremic patients undergoing dialysis treatment and they suggested that this unphysiological condition could be possibly induced by mitochondrial dysfunction.

Background Access to medical records on the Internet has been reported to be acceptable and popular with patients, although most published evaluations have been of primary care or office-based practice. We tested the feasibility and acceptability of making unscreened results and data from a complex chronic disease pathway (renal medicine) available to patients over the Internet in a project involving more than half of renal units in the UK. Methods Content and presentation of the Renal PatientView (RPV) system was developed with patient groups. It was designed to receive information from multiple local information systems and to require minimal extra work in units. After piloting in 4 centres in 2005 it was made available more widely. Opinions were sought from both patients who enrolled and from those who did not in a paper survey, and from staff in an electronic survey. Anonymous data on enrolments and usage were extracted from the webserver. Results By mid 2011 over 17,000 patients from 47 of the 75 renal units in the UK had registered. Users had a wide age range (<10 to >90 yrs) but were younger and had more years of education than non-users. They were enthusiastic about the concept, found it easy to use, and 80% felt it gave them a better understanding of their disease. The most common reason for not enrolling was being unaware of the system. A minority of patients had security concerns, and these were reduced after enrolling. Staff responses were also strongly positive. They reported that it aided patient concordance and disease management, and increased the quality of consultations with a neutral effect on consultation length. Neither patient nor staff responses suggested that RPV led to an overall increase in patient anxiety or to an increased burden on renal units beyond the time required to enrol each patient. Conclusions Patient Internet access to secondary care records concerning a complex chronic disease is feasible and popular, providing an increased

Introduction Psychosocial factors have been implicated as being important in the onset and/or exacerbation of urticaria. Aim To examine both personality factors of patients with chronic idiopathic urticaria (CIU) and the correlations between illness duration, severity of itching, urticaria activity score (UAS) and temperament-character dimensions. Material and methods A total number of 70 CIU patients and 60 healthy individuals were included in the study. The Temperament and Character Inventory (TCI) was administered individually. The relationship between UAS, illness duration and severity of pruritus and TCI subscales were evaluated. Results The CIU group had significantly higher scores of novelty seeking and lower scores of cooperativeness, reward dependence and self-directedness than the control group. Conclusions The current study shows that CIU patients have distinctive temperament and character dimensions when compared with the control group. We suggest that evaluation and treatment of CIU should also include psychosomatic approaches in clinical practice. PMID:26161056

The pharmacokinetics of the dihydropyridine calcium antagonist isradipine has been examined in 8 healthy volunteers, 7 patients with non-cirrhotic chronic liver disease (CLD), and 8 patients with biopsy-proven cirrhosis (CIR). Isradipine was simultaneously given orally (12C 5 mg) and i.v. (13C 1 mg). Systemic availability was significantly increased from 17% to 16% in controls and CLD, respectively, to 37% in CIR. The corresponding systemic clearances averaged 1.1, 0.9 and 0.6 l.min-1, the reduction in cirrhotics being significant. Both aminopyrine demethylation capacity, a measure of hepatic microsomal function, and indocyanine green disappearance, a measure of hepatic perfusion, were correlated with the reduction in systemic clearance, and the reduction in oral clearance was correlated with the reciprocal of the serum bile acid concentration. The loss of first-pass extraction should be considered when this calcium antagonist is given perorally in patients with hepatic cirrhosis.

Knowledge Management (KM) can be seen as the process of capturing, developing, sharing, and effectively using organizational knowledge. In this context, the work presented here proposes a KM System to be used in the scope of chronic patient control and monitoring for distributed research projects. It was designed in order to enable communication between patient and doctors, as well as to be usedbythe researchers involved in the project for its management. The proposed model integrates all the information concerning every patient and project management tasks in the Institutional Memory of a KMSystem and uses an ontology to maintain the information and its categorization independently. Furthermore, taking the philosophy of intelligent agents, the system will interact with the user to show him the information according to his preferences and access rights. Finally, three different scenarios of application are described.

Recent years have seen the emergence of noninvasive ventilation (NIV) as an important tool for management of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Several well conducted studies in the recent years have established its role in the initial, as well as later management of these patients. However, some grey areas remain. Moreover, data is emerging on the role of long term nocturnal NIV use in patients with very severe stable COPD. This review summarizes the evidence supporting the use of NIV in various stages of COPD, discuss the merits as well as demerits of this novel ventilatory strategy and highlight the grey areas in the current body of knowledge.

Atherosclerosis is a complex inflammatory disease involving aberrant immune and tissue healing responses, which begins with endothelial dysfunction and ends with plaque development, instability and rupture. The increased risk for coronary artery disease in patients with rheumatologic diseases highlights how aberrancy in the innate and adaptive immune system may be central to development of both disease states and that atherosclerosis may be on a spectrum of immune-mediated conditions. Recognition of the tight association between chronic inflammatory disease and complications of atherosclerosis will impact the understanding of underlying pathogenic mechanisms and change diagnostic and therapeutic approaches in patients with rheumatologic syndromes as well as patients with coronary artery disease. In this review, we provide a summary of the role of the immune system in atherosclerosis, discuss the proposed mechanisms of accelerated atherosclerosis seen in association with rheumatologic diseases, evaluate the effect of immunosuppression on atherosclerosis and provide updates on available risk assessment tools, biomarkers and imaging modalities. PMID:27042216
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in adults in the United States and worldwide. Depression is a common comorbidity in this population, but often goes undiagnosed in persons with COPD. Because the presence of depression has the potential to negatively impact COPD-related outcomes, it is essential for health care practitioners involved in the care of patients with COPD to diagnose and treat COPD and the associated comorbidities, including depression. Although there is a lack of comprehensive guidelines for treating depression in those with COPD, an algorithm has been proposed to screen and manage depression in these patients. Several questionnaires are available that can be used to assess and assist in diagnosing depression in these patients. Following diagnosis, antidepressant therapy should be considered along with nonpharmacological strategies, such as pulmonary rehabilitation and cognitive behavioral therapy.

Patients' education belongs to the most efficient therapeutic measures in the management of asthma, chronic bronchitis and pulmonary emphysema. The following paper reports the experience in the educational programme at the Polyclinic for Respiratory Diseases in Zagreb. Each patient's education lasted 5 days, 3 lessons per day, in groups of 10-15 persons. The education was carried out by a teaching team consisting of pulmonologists, psychosomatologist, pharmacist, physiotherapist and biometeterologist. From March 1995 to February 1996 135 persons completed the educational programme, 65 of whom were asthma patients. Data on cough and dyspnoea, skills in inhaler and breathing technique were collected at the beginning and 3 months after the education in all asthma patients. Three months after the education the asthma patients showed a significant decrease in dyspnoea and a significant improvement in inhaler and breathing technique. A standard questionnaire was given to all patients at the end of the education and in more than 80% the education was well accepted by the patients. Initial results are encouraging and the programme should be expanded to all parts of Croatia.

Ibrutinib is a Bruton tyrosine kinase inhibitor approved for the treatment of patients with relapsed refractory chronic lymphocytic leukemia (RR-CLL). We describe the characteristics, causes of discontinuation, and outcomes in patients who discontinued treatment with ibrutinib. One hundred twenty-seven patients were enrolled in various clinical trials of ibrutinib, with or without rituximab, at our center. Thirty-three (26%) patients have discontinued ibrutinib to date. The majority of those patients had high-risk features: 94% with unmutated immunoglobulin heavy chain variable gene rearrangement, 58% with del(17p) by fluorescence in situ hybridization, and 54% with a complex karyotype. Causes of discontinuation were disease transformation (7), progressive CLL (7), stem cell transplantation (3), adverse events (11), serious adverse events/deaths (3), and miscellaneous reasons (2). Twenty five patients (76%) died after discontinuing ibrutinib; the median overall survival was 3.1 months after discontinuation. Most patients with RR-CLL who discontinued ibrutinib early were difficult to treat and had poor outcomes.

Objective To explore the electroencephalogram (EEG) characteristics in patients with chronic fatigue syndrome (CFS) using brain electrical activity mapping (BEAM) and EEG nonlinear dynamical analysis. Methods Forty-seven outpatients were selected over a 3-month period and divided into an observation group (24 outpatients) and a control group (23 outpatients) by using the non-probability sampling method. All the patients were given a routine EEG. The BEAM and the correlation dimension changes were analyzed to characterize the EEG features. Results 1) BEAM results indicated that the energy values of δ, θ, and α1 waves significantly increased in the observation group, compared with the control group (P<0.05, P<0.01, respectively), which suggests that the brain electrical activities in CFS patients were significantly reduced and stayed in an inhibitory state; 2) the increase of δ, θ, and α1 energy values in the right frontal and left occipital regions was more significant than other encephalic regions in CFS patients, indicating the region-specific encephalic distribution; 3) the correlation dimension in the observation group was significantly lower than the control group, suggesting decreased EEG complexity in CFS patients. Conclusion The spontaneous brain electrical activities in CFS patients were significantly reduced. The abnormal changes in the cerebral functions were localized at the right frontal and left occipital regions in CFS patients. PMID:26869792

Patients with chronic thromboembolic pulmonary hypertension (CTEPH) experience debilitating symptoms that have a negative impact on their quality of life (QoL) in terms of physical capability, psychological wellbeing and social relationships. The use of QoL measurement tools is important in the assessment of treatment efficacy and in guiding treatment decisions. However, despite the importance of QoL, particularly to the patient, it remains under-reported in clinical studies of CTEPH therapy. CTEPH is unique in pulmonary hypertension in that it is potentially curable by surgery; however, a proportion of patients either have residual PH following surgery or are not operable. Although some patients with CTEPH have been treated off-label with pulmonary arterial hypertension-specific therapies, there have been few randomised controlled trials of these therapies in patients with CTEPH. Moreover, in these trials QoL outcomes are variably assessed, and there is little consistency in the tools used. Here we review the assessment of QoL in patients with CTEPH and the tools that have been used. We also discuss the effect of surgical intervention and medical therapies on QoL. We conclude that further studies of QoL in patients with CTEPH are needed to further validate the optimal QoL tools. PMID:27076580

The aim of this study was to compare the frequency and severity of chronic periodontitis (CP) in systemic lupus erythematosus (SLE) patients with individuals without rheumatic diseases. Seventy-five patients with SLE were compared to 75 individuals without rheumatic diseases (control group) matched for age, educational level, and income. The activity of SLE was assessed with the Systemic Lupus Erythematosus Disease Activity Index 2000. Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index for Systemic Lupus Erythematosus evaluated SLE-related damage. Dental evaluation included measuring plaque index and parameters of periodontal disease (probing depth, clinical attachment level, and bleeding on probing). Fifty-one (68 %) SLE patients and 42 (56 %) control individuals had CP (p = 0.13). Periodontal status was similar in both groups. Considering only individuals with CP, SLE patients were younger than controls (40.7 ± 9.8 versus 46.14 ± 12.5 years of age, p = 0.02). CP was not associated with activity or therapeutics in SLE patients. Severity of periodontal parameters was similar in SLE patients and control subjects; however, CP occurred earlier in SLE patients.
Objectives: This review explores the challenges and solutions in educating patients with chronic kidney disease (CKD) to lower serum phosphorus while avoiding protein insufficiency and hypercalcemia. Methods: A literature search including terms “hyperphosphatemia,” “patient education,” “food fatigue,” “hypercalcemia,” and “phosphorus–protein ratio” was undertaken using PubMed. Results: Hyperphosphatemia is a strong predictor of mortality in advanced CKD and is remediated via diet, phosphorus binders, and dialysis. Dietary counseling should encourage the consumption of foods with the least amount of inorganic or absorbable phosphorus, low phosphorus-to-protein ratios, and adequate protein content, and discourage excessive calcium intake in high-risk patients. Emerging educational initiatives include food labeling using a “traffic light” scheme, motivational interviewing techniques, and the Phosphate Education Program – whereby patients no longer have to memorize the phosphorus content of each individual food component, but only a “phosphorus unit” value for a limited number of food groups. Phosphorus binders are associated with a clear survival advantage in CKD patients, overcome the limitations associated with dietary phosphorus restriction, and permit a more flexible approach to achieving normalization of phosphorus levels. Conclusion: Patient education on phosphorus and calcium management can improve concordance and adherence and empower patients to collaborate actively for optimal control of mineral metabolism.

The application of the principle of autonomy, which is considered a cornerstone of contemporary bioethics, is sometimes in obvious contradiction with the principle of beneficence. Indeed, it may happen in chronic care that the preferences of the health care provider (HCP), who is largely focused on the prevention of long term complications of diseases, differ from those, more present oriented, preferences of the patient. The aims of this narrative review are as follows: 1) to show that the exercise of autonomy by the patient is not always possible; 2) where the latter is not possible, to examine how, in the context of the autonomy principle, someone (a HCP) can decide what is good (a treatment) for someone else (a patient) without falling into paternalism. Actually this analysis leads to a paradox: not only is the principle of beneficence sometimes conflicting with the principle of autonomy, but physician's beneficence may enter into conflict with the mere respect of the patient; and 3) to propose a solution to this paradox by revisiting the very concepts of the autonomous person, patient education, and trust in the patient-physician relationship: this article provides an ethical definition of patient education.

Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults in Western countries. Fludarabine-based regimens demonstrate higher response rates in younger patients but have a significant risk of infection and are thus poorly tolerated by older, frail patients. Anti-CD20 monoclonal antibodies have added to the efficacy of chemotherapy in CLL. Obinutuzumab is a potent Type II anti-CD20 monoclonal antibody with enhanced antibody-dependent cellular toxicity and direct cell death compared with rituximab. In Phase I studies, infusion reactions and neutropenia were the predominant toxicities. Phase II studies demonstrated efficacy both as a single agent and in combination with chemotherapy in patients with CLL. The CLL11 trial was a Phase III randomized trial of chlorambucil alone or with either obinutuzumab or rituximab in elderly, unfit patients. Progression-free survival (the primary end point) was 26.7 months for patients receiving obinutuzumab plus chlorambucil versus 16.3 months for those receiving rituximab plus chlorambucil and 11.1 months for those receiving chlorambucil alone (P<0.001). Overall survival was improved for patients receiving obinutuzumab plus chlorambucil versus chlorambucil alone (P=0.002). This trial led to the US Food and Drug Administration (FDA) approval of obinutuzumab in this patient population.

This study aims to explore patient's concerns when discussing sexual problems caused by chronic low back pain with their healthcare provider. It also aims to identify factors influencing and limiting such communication. A cross-sectional analysis of 100 consenting chronic low back pain sexually active patients was carried out. Patients answered questions on their disease characteristics and sex life. They also mentioned prohibitions of discussing sex with their healthcare provider and their expectations of such discussion. Factors influencing patient's experiences were analyzed. Median of chronic low back pain duration was 36 (24-72) months and back pain intensity using visual analogical scale (0-100 mm) was 50 ± 10.7 mm. Eighty-one percent of our patients complained of sexual problems, 66 % have never discussed the subject with their healthcare provider. Barriers which prevent discussion on sex include the taboo character of the topic, inappropriateness of visit conditions, and patient disinterest in sex. Ninety-three percent of patients expressed the need of sexual problems' management in chronic low back pain consulting. Seventy-four percent expected information and advice from their healthcare provider about recommended intercourse positions so as to avoid pain. Thirty-three percent of patients wanted their partner to be involved in the discussion and 81 % preferred talking with a healthcare provider of the same gender. Ability to communicate on the topic was associated with the decrease of patient sexual satisfaction and limited by patient illiteracy. Our study evidences that sex discussion between patient and healthcare provider is restricted by several barriers and that patients expect more involvement from their healthcare provider on the subject. Illiteracy and level of sexual satisfaction seem to be the strongest factors influencing this communication.

Half of all men experience symptoms of prostatitis at some time in their lives, but the etiology is unknown for more than 90% of patients. Optimal clinical and culture methods were used to select 135 men with chronic prostatitis refractory to multiple previous courses of antimicrobial therapy. The subjects had no evidence of structural or functional lower genitourinary tract abnormalities of bacteriuria or bacterial prostatitis by traditional clinical tests, or of urethritis or urethral pathogens by culture. Specific PCR assays detected Mycoplasma genitalium, Chlamydia trachomatis, or Trichomonas vaginalis in 10 patients (8%). Broad-spectrum PCR tests detected tetracycline resistance-encoding genes, tetM-tetO-tetS, in 25% of patients and 16S rRNA in 77% of subjects. The tetM-tetO-tetS-positive cases constituted a subset of the 16S rRNA-positive cases. Patients with 16S rRNA were more likely to have > or = 1,000 leukocytes per mm3 in their expressed prostatic secretion than men whose prostate biopsy specimens were negative for 16S rRNA (P < 0.001). Based on direct sequencing and repetitive cloning, multiple sources of 16S rRNA were observed in individual patients. Sequences of 29 cloned PCR products revealed 16S rRNAs distinct from those of common skin and gut flora. These findings suggest that the prostate can harbor microorganisms that are not detectable by traditional approaches. These organisms may be associated with inflammation in the expressed prostatic secretions. Molecular methods hold great promise for identifying culture-resistant microorganisms in patients with chronic prostatitis. PMID:8940458

Aluminum has been proposed as the causative agent in dialysis encephalopathy syndrome. We prospectively assessed whether other, less severe, neuropsychologic abnormalities were also associated with aluminum. A total of 16 patients receiving chronic dialytic therapy were studied. The deferoxamine infusion test (DIT) was used to assess total body aluminum burden. Neurologic function was evaluated by quantitative measures of asterixis, myoclonus, motor strength, and sensation. Cognitive function was assessed by measures of dementia, memory, language, and depression. There were four patients with a positive DIT (greater than 125 micrograms/L increment in serum aluminum) that was associated with an increase in the number of neurologic abnormalities observed, as well as an increase in severity of myoclonus, asterixis, and lower extremity weakness. Patients with a positive DIT also showed significant impairment in memory; however, no differences were noted on tests of dementia, depression, or language. There was no significant correlation between sex, age, presence of diabetes, mode of dialysis, years of chronic renal failure, years of dialysis or years of aluminum ingestion and any neurologic or neurobehavioral measurement, serum aluminum level, or DIT. These changes may represent early aluminum-associated neurologic dysfunction.

Chronic fatigue syndrome is a serious, complex and debilitating fatigue characterized by intense physical and mental, that does not subside significantly after rest and worsens with activity The appearance of the disease requires the patient to reduce the activity diminished their quality of life. While there is no cure, the complexity of the disease requires an interdisciplinary approach where the mission of nursing is to identify the least healthy responses of each individual in relation to their health status and interfering with them by means of specific support, integrated support and follow a care plan tailored to the individual needs of each individual. Fatigue, pain, sleep pattern disturbance, anxiety and lack of knowledge are the most prevalent health problems in patients treated at the Chronic Fatigue Unit, University Hospital Vail d'Hebron. Thus, in these problems and by developing a customized care plan process we use for health education as a tool for influencing the control of symptoms through interventions to improve the learning support, emotional support and Accompanying with the aim of helping the patient and their relatives are an adaptive response to their new health status and thus improve the quality of life.

Femoroacetabular impingement is a diagnosis that is often missed in patients with chronic groin pain. The condition often appears in young athletes. An anatomic deformity of the femoral head and the acetabular ridge causes an impingement that damages the subchondral tissue. This damage can result in sharp pain in the groin during specific hip movements and the acetabular labrum may also be ruptured. Diagnosing femoroacetabular impingement and a labral tear can be a challenge. We present the case of a 19-year-old male who twisted his right hip joint during a game of football. Physiotherapy only aggravated the pain. Further diagnostics showed femoroacetabular impingement and a labral tear. Arthroscopic intervention in the hip joint by an orthopedic surgeon lead to immediate pain relief, and two years after surgery the patient is still free of pain and has returned playing sport at his previous level. Femoroacetabular impingement can be a cause of chronic groin pain in young athletes. Hip arthroscopy is a safe and effective treatment, enabling the patient to return to playing sport at their previous level.

A study was carried out into the hematological abnormalities of peripheral blood bone marrow in patients chronically exposed to benzene. The metabolic biotransformation and the mechanisms involved in toxicity are described. Hematological data are described and discussed. Macrocytosis and lymphopenia are the earliest hematological signs of benzene toxicity. Bone marrow abnormalities are demonstrated by the complementary methods of cytology and histology. Global hypocellularity was mainly due to the granulocytic series. Mastocytosis, eosinophilia and magakariocytic abnormalities are also presented. Inflammatory abnormalities and signs of dismyelopoiese could also be observed. The importance of peripheral blood abnormalities and the need for a critical approach to this important public health problem are emphasized.

The authors undertook a retrospective review of the clinical records and radiologic findings of eight children with chronic, recurrent multifocal osteomyelitis (CRMO). This disease is a recognized clinicopathologic entity with typical radiographic findings, mostly in the metaphyses of the long bones. The diagnosis is one of exclusion without pathognomonic findings. The patients were treated with non-steroidal anti-inflammatory drugs. There was no evidence of altered bone growth or abnormal joint development. It is concluded that CRMO is a distinct clinical entity that is different from acute or subacute bacterial osteomyelitis. Recognition of this condition is important to avoid treatment with antibiotics and repeated operations.

Abstract The aim of this study was to investigate changes of synaptic area of the spinothalamic tract and its thalamocortical pathway (STT) in the thalamus in chronic patients with putaminal hemorrhage. Twenty four patients with a lesion in the ventral posterior lateral nucleus (VPL) of the thalamus following putaminal hemorrhage were recruited for this study. The subscale for tactile sensation of the Nottingham Sensory Assessment (NSA) was used for the determination of somatosensory function. Diffusion tensor tractography of the STT was reconstructed using the Functional Magnetic Resonance Imaging of the Brain Software Library. We classified patients according to 2 groups: the VPL group, patients whose STTs were synapsed in the VPL; and the non-VPL group, patients whose STTs were synapsed in other thalamic areas, except for the VPL. Thirteen patients belonged to the VPL group, and 8 patients belonged to the non-VPL group. Three patients were excluded from grouping due to interrupted integrity of the STTs. The tactile sensation score of the NSA in the non-VPL group (10.50 ± 0.93) was significantly decreased compared with that of the VPL group (19.45 ± 1.33) (P < 0.05). We found that 2 types of patient had recovered via the VPL area or other areas of the STT. It appears that patients who showed shifting of the thalamic synaptic area of the STT might have recovered by the process of thalamic reorganization following thalamic injury. In addition, thalamic reorganization appears to be related to poorer somatosensory outcome. PMID:26313781

The sympathetic nervous system is affected in patients with chronic renal failure (CRF). This study tested the hypothesis that patients with CRF have an altered skeletal muscle metaboreflex. Twenty patients with CRF and 18 healthy subjects of similar age participated in the study. The muscle metaboreflex was determined based on heart rate (HR), mean arterial pressure, calf blood flow and calf vascular resistance (CVR) in response to handgrip exercise. The control of vascular resistance in the calf muscle mediated by the metaboreflex was estimated by subtracting the area under the curve with circulatory occlusion from that without occlusion. Arterial pressure and HR responses during exercise and recovery were similar in two groups of subjects. In the control group, CVR increased during exercise and remained elevated during circulatory occlusion, whereas no significant change was seen in the patients. Thus, the index of the metaboreflex was 7·82 ± 9·57 in the patients versus16·52 ± 14 units in the controls. The findings demonstrate that patients with CRF have a decreased vascular resistance response in the calf during the handgrip exercise, which suggests that CRF condition attenuates this reflex.

Patients with purine analogue-refractory chronic lymphocytic leukemia (CLL) have short survival and limited treatment options. Defining the best salvage strategies for this population is challenging, because limited data are available from clinical trials, and because studies have enrolled mixed populations (patients with recurrent and refractory disease or patients with refractory disease and Richter transformation). Moreover, patients with refractory CLL have a high incidence of unfavorable molecular and clinical features, such as high-risk genomic profiles, unmutated immunoglobulin heavy-chain genes, expression of zeta-chain-associated protein kinase 70, and bulky lymphadenopathies. These patients are also severely immunosuppressed because of the underlying disease and the treatments received, and experience a high rate of infectious complications that pose an additional difficulty in selecting treatment. Despite these challenges, in parallel with better characterizations of the biologic features of refractory CLL, the number of available treatment modalities for this population has increased. Several chemoimmunotherapy combinations have been developed, and novel agents with a different mechanism of action are being investigated in clinical trials. Furthermore, allogeneic stem cell transplantation with nonmyeloablative conditioning regimens is a therapeutic strategy that is increasingly offered to patients with refractory CLL.

The role of food additives in chronic urticaria (CU) is still under investigation. In this study, we aimed to explore the association between food additives and CU by using the basophil activation test (BAT). The BAT using 15 common food additives was performed for 15 patients with CU who had a history of recurrent urticarial aggravation following intake of various foods without a definite food-specific IgE. Of the 15 patients studied, two (13.3%) showed positive BAT results for one of the tested food additives. One patient responded to monosodium glutamate, showing 18.7% of CD203c-positive basophils. Another patient showed a positive BAT result to sodium benzoate. Both patients had clinical correlations with the agents, which were partly determined by elimination diets. The present study suggested that at least a small proportion of patients with CU had symptoms associated with food additives. The results may suggest the potential utility of the BAT to identity the role of food additives in CU.

Chronic obstructive pulmonary disease (COPD) is associated with chronic inflammation affecting predominantly the lung parenchyma and peripheral airways that results in largely irreversible and progressive airflow limitation. This inflammation is characterized by increased numbers of alveolar macrophages, neutrophils, T lymphocytes (predominantly TC1, TH1, and TH17 cells), and innate lymphoid cells recruited from the circulation. These cells and structural cells, including epithelial and endothelial cells and fibroblasts, secrete a variety of proinflammatory mediators, including cytokines, chemokines, growth factors, and lipid mediators. Although most patients with COPD have a predominantly neutrophilic inflammation, some have an increase in eosinophil counts, which might be orchestrated by TH2 cells and type 2 innate lymphoid cells though release of IL-33 from epithelial cells. These patients might be more responsive to corticosteroids and bronchodilators. Oxidative stress plays a key role in driving COPD-related inflammation, even in ex-smokers, and might result in activation of the proinflammatory transcription factor nuclear factor κB (NF-κB), impaired antiprotease defenses, DNA damage, cellular senescence, autoantibody generation, and corticosteroid resistance though inactivation of histone deacetylase 2. Systemic inflammation is also found in patients with COPD and can worsen comorbidities, such as cardiovascular diseases, diabetes, and osteoporosis. Accelerated aging in the lungs of patients with COPD can also generate inflammatory protein release from senescent cells in the lung. In the future, it will be important to recognize phenotypes of patients with optimal responses to more specific therapies, and development of biomarkers that identify the therapeutic phenotypes will be important.

The present study investigated the articulatory implementation deficits of Broca’s and Wernicke’s aphasics and their potential neuroanatomical correlates. Five Broca’s aphasics, two Wernicke’s aphasics, and four age-matched normal speakers produced consonant-vowel-(consonant) real word tokens consisting of [m, n] followed by [i, e, a, o, u]. Three acoustic measures were analyzed corresponding to different properties of articulatory implementation: murmur duration (a measure of timing), amplitude of the first harmonic at consonantal release (a measure of articulatory coordination), and murmur amplitude over time (a measure of laryngeal control). Results showed that Broca’s aphasics displayed impairments in all of these parameters, whereas Wernicke’s aphasics only exhibited greater variability in the production of two of the parameters. The lesion extent data showed that damage in either Broca’s area or the insula cortex was not predictive of the severity of the speech output impairment. Instead, lesions in the upper and lower motor face areas and the supplementary motor area resulted in the most severe implementation impairments. For the Wernicke’s aphasics, the posterior areas (superior marginal gyrus, parietal, and sensory) appear to be involved in the retrieval and encoding of lexical forms for speech production, resulting in increased variability in speech production.

Perforating dermatoses are a group of skin diseases characterized by transepidermal elimination of dermal material. The disease is divided into two groups: the primary group and the secondary group. The classical or primary perforating dermatoses are subdivided into four types according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is known as acquired perforating dermatosis. The term was proposed in 1989 by Rapini to designate the perforating dermatoses affecting adult patients with systemic disease, regardless of the dermal materials eliminated. This report describes a case of the disease with elimination of collagen and elastic fibers in a patient with chronic renal failure. PMID:28300880

Vegetarian diet is a very old practice that is liable to confer some health benefits. Recent studies have demonstrated that modification of the dietary pattern with a reduction of animal protein intake and increased consumption of plant-based foods could influence cardiovascular risk profile and mortality rate. Moreover, phosphate bioavailability from plant proteins is reduced. These statements could lead to some benefits for chronic kidney disease (CKD) patients. This review summarizes the characteristics and benefits of vegetarian diets in the general population and the potential beneficial effects of such a diet on phosphate balance, insulin sensitivity, and the control of metabolic acidosis in CKD patients. Potential drawbacks exist when a vegetarian diet is associated with protein intake that is too restrictive and/or insufficient energy intake, justifying an early and regular nutritional follow-up jointly assumed by a nephrologist and a renal dietitian.

Wandering spleen or splenoptosis is an uncommon entity and often an asymptomatic finding of acute abdomen in the emergency department. A high index of suspicion for splenic torsion is required, particularly in patients with known splenomegaly, as this condition could potentially lead to splenic infarction. Recognition of this condition can help avoid potential confusion with acute abdomen of other aetiologies. Herein, we present a unique case of wandering spleen with chronic torsion, which, to the best of our knowledge, has never been described in an elderly patient with haemoglobin H thalassaemia. We also review the literature for the aetiology and pathogenesis of wandering spleen, and discuss the relevant diagnostic modalities and treatment options. PMID:25630326
Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

Chronic kidney disease (CKD) patients typically self-manage their disease-care program. Self-management requires the investment of considerable time and energy in health management and in following the multifaceted CKD treatment regimen. CKD, a progressive disease, is classified into five stages that correspond to the five stages of decline in kidney function, as measured using the glomerular filtration rate (GRF). Each of these stages requires that a patient modify his / her lifestyle and shoulder the responsibility for day-to-day health management tasks. Key to promoting self-management is the partnership and collaboration between healthcare providers and patients. Tasks in this partnership include patient assessment and communication, regimen adherence, emotional management, negotiation of care plans, and the enhancement of self-efficacy, with the aims of creating positive changes in behavior, promoting correct symptoms interpretation and reporting, and promoting the appropriate use of resources. Nurses may help patients maneuver this initially frightening and sometimes difficult terrain with strategies that are tailored to each CKD stage.

Patients with chronic kidney disease (CKD) are at increased risk for both thrombotic events and bleeding. The early stages of CKD are mainly associated with prothrombotic tendency, whereas in its more advanced stages, beside the prothrombotic state, platelets can become dysfunctional due to uremic-related toxin exposure leading to an increased bleeding tendency. Patients with CKD usually require anticoagulation therapy for treatment or prevention of thromboembolic diseases. However, this benefit could easily be offset by the risk of anticoagulant-induced bleeding. Treatment of patients with CKD should be based on evidence from randomized clinical trials, but usually CKD patients are excluded from these trials. In the past, unfractionated heparins were the anticoagulant of choice for patients with CKD because of its independence of kidney elimination. However, currently low-molecular-weight heparins have largely replaced the use of unfractionated heparins owing to fewer incidences of heparin-induced thrombocytopenia and bleeding. We undertook this review in order to explain the practical considerations for the management of anticoagulation in these high risk population.

We aim to determine the relationship between bone mineral density (BMD), measured by T- and Z-score, and mortality risk in hemodialysis (HD) patients. We also investigate which are the most suitable skeletal sites for predicting mortality rate. We analyzed the survival of 102 patients who had been treated with chronic HD according to BMD. Patients with a T-score ≤2.5 at the middle, ultradistal and proximal part of the forearm had a higher mortality risk than those with a T-score of -2.5 or higher. Furthermore, no statistically significant association was found between loss of bone mass at other measuring points-lumbar spine (anteroposterior orientation from L1-L4) and hip (neck, trochanter, intertrochanter, total and Ward's triangle)-and mortality risk. We were also interested in exploring the relationship between Z-score at different skeletal regions and mortality risk. We found that patients with a Z-score of -1 or lower at all three parts of the forearm had a greater mortality risk. It is also worth noting that the Z-score at all three parts of the forearm was a more apparent predictor of mortality, compared to the T-score at the same skeletal regions. This empirical analysis showed that BMD assessments should be obtained at the forearm, due to the good predictability of this skeletal site regarding mortality of HD patients. Moreover, data concerning bone density should be reported as Z-scores.

Nails have a limited number of reactive patterns to disease. Accordingly, toenail changes of different etiologies may mimic onychomycosis. OBJECTIVE To determine the prevalence of toenail onychomycosis among patients with leg ulcer and toenail abnormalities attending a dermatology clinic. METHODS A cross-sectional study was conducted through the analysis of clinical records and results of mycological examination. RESULTS A total of 81 patients were included, with a median age of 76.0 years. Most ulcers were of venous etiology, followed by those of mixed and arterial pathogenesis. The mycological evaluation confirmed the diagnosis of onychomycosis in 27.2% of the patients. The etiologic agent was a dermatophyte in 59.1% of isolates in nail samples, while Trichophyton interdigitale was the most frequent fungal species (40.9%). CONCLUSIONS Most toenail abnormalities in patients with chronic leg ulcer were not onychomycosis. This study highlights the importance of systematic mycological examination in these patients, in order to avoid overtreatment with systemic antifungals, unnecessary costs and side effects.

Chronic kidney disease (CKD) is an independent risk factor for cardiovascular disease. Thus, patients with CKD often require treatment with cardiovascular drugs, such as antiplatelet, antihypertensive, anticoagulant, and lipid-lowering agents. There is significant inter-patient variability in response to cardiovascular therapies, which contributes to risk for treatment failure or adverse drug effects. Pharmacogenomics offers the potential to optimize cardiovascular pharmacotherapy and improve outcomes in patients with cardiovascular disease, though data in patients with concomitant CKD are limited. The drugs with the most pharmacogenomic evidence are warfarin, clopidogrel, and statins. There are also accumulating data for genetic contributions to β-blocker response. Guidelines are now available to assist with applying pharmacogenetic test results to optimize warfarin dosing, selection of antiplatelet therapy after percutaneous coronary intervention, and prediction of risk for statin-induced myopathy. Clinical data, such as age, body size, and kidney function have long been used to optimize drug prescribing. An increasing number of institutions are also implementing genetic testing to be considered in the context of important clinical factors to further personalize drug therapy for patients with cardiovascular disease.

The global prevalence of allergic rhinitis has been on the increase and recent clinical experience in Malta has shown a similar trend. The aim of this study was to investigate the role of atopy in 415 patients presenting with rhinitis of at least 3 months duration, and to identify the common allergens responsible. Presenting clinical features, past and family history of seasonal allergic symptoms, exposure to cigarette smoking, pet ownership and occupation were analysed. All patients were skin tested for common allergens. Fifty-five per cent of patients were atopic, the main allergens responsible being house dust mite, cat dander and grass pollen. Rhinorrhoea and sneezing were significantly more common in atopic patients, who were more likely to have a past history and family history of seasonal asthma, eczema or rhinoconjunctivitis. Skin test-negative patients with idiopathic rhinitis were mostly females and tended to present a decade later. Differentiation between atopic and idiopathic chronic rhinitis may be helpful in the clinical setting in order to help predict response to treatment.

Introduction Polyneuropathy leads to postural instability and an increased risk of falling. We investigated how impaired motor impairment and proprioceptive input due to neuropathy influences postural strategies. Methods Platformless bisegmental posturography data were recorded in healthy subjects and patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Each subject stood on the floor, wore a head and a hip electromagnetic tracker. Sway amplitude and velocity were recorded and the mean direction difference (MDD) in the velocity vector between trackers was calculated as a flexibility index. Results Head and hip postural sway increased more in patients with CIDP than in healthy controls. MDD values reflecting hip strategies also increased more in patients than in controls. In the eyes closed condition MDD values in healthy subjects decreased but in patients remained unchanged. Discussion Sensori-motor impairment changes the balance between postural strategies that patients adopt to maintain upright quiet stance. Motor impairment leads to hip postural strategy overweight (eyes open), and prevents strategy re-balancing when the sensory context predominantly relies on proprioceptive input (eyes closed).

Goals To examine a wide range of sociodemographic and clinical characteristics as potential predictors of complementary and alternative medicine (CAM) use among chronic liver disease (CLD) patients, with a focus on CAM therapies with the greatest potential for hepatotoxicity and interactions with conventional treatments. Background There is some evidence that patients with CLD commonly use CAM to address general and CLD-specific health concerns. Study Patients enrolled in a population-based surveillance study of persons newly diagnosed with CLD between 1999 and 2001 were asked about current use of CAM specifically for CLD. Socio-demographic and clinical information was obtained from interviews and medical records. Predictors of CAM use were examined using univariate and multivariate logistic regression analysis. Results Of the 1040 participants, 284 (27.3%) reported current use of at least 1 of 3 CAM therapies of interest. Vitamins or other dietary supplements were the most commonly used therapy, reported by 188 (18.1%) patients. This was followed by herbal medicine (175 patients, 16.8%) and homeopathy (16 patients, 1.5%). Several characteristics were found to be independent correlates of CAM use: higher education and family income, certain CLD etiologies (alcohol, hepatitis C, hepatitis C and alcohol, and hepatitis B), and prior hospitalization for CLD. Conclusions Use of CAM therapies that have the potential to interact with conventional treatments for CLD was quite common among this population-based sample of patients with CLD. There is a need for patient and practitioner education and communication regarding CAM use in the context of CLD. PMID:19779363

Non-adherence to prescription is common among hemodialysis (HD) patients and has been associated with significant morbidity. At least 50% of HD patients are believed to be non-adherent to some part of their treatment. We aimed to assess the prevalence of non-adherence to dialysis prescription among 100 chronic HD patients. We explored the relationship between non-adherence on one hand and socioeconomic profile, depression scores and cognitive function on the other hand. The impact of patients' non-adherence on nutritional status, quality of life and dialysis adequacy was also assessed. The mean age of the study group was 50.51 ± 12.0 years. There were 62 females and 38 males in the study. Thirty-six patients (36%) were non-compliant to their dialysis prescription. No significant differences were detected between compliant and non-compliant patients in their education level and employment status. Inter-dialytic weight gain, serum phosphorus and depression scores were significantly higher in non-compliant patients compared with compliant patients, whereas body weight, serum albumin, serum calcium, quality of life scores and nutrition scores were significantly higher in compliant patients (P <0.05). In conclusion, non-adherence is highly prevalent among chronic HD patients and is associated with poor quality of life, depression and malnutrition.

In Argentina, there have been no studies aimed at establishing the prevalence of dysglycaemia (impaired fasting glucose [IFG], impaired glucose tolerance [IGT] and diabetes mellitus [DM]) in patients with chronic kidney disease (CKD). Our group decided to conduct an observational study to evaluate the frequency with oral glucose tolerance test (OGTT) in CKD patients with no previous data for dysglycaemia in their medical records. OGTT was performed in 254 patients (60.62% male) with stage 3, 4 and 5 CKD under conservative treatment, haemodialysis or transplantation. Results for DM were found in 10 patients according to fasting glucose alone (3.94%; 95% CI: 1.35-6.53%), 11 patients with exclusively the second hour criterion (4.33%; 95% CI: 1.63-7.03%), 15 with both criteria (5.91%; 95% CI: 2.81-9.00%) and 36 patients with at least one criteria (14.17%; 95% CI: 9.69-18.66%). In a multivariate analysis, DM was associated with waist circumference (OR=1.033 per cm; 95% CI, 1.005 to 1.062; P=.019) and with conservative treatment vs. replacement therapy (OR=0.41; 95% CI: 0.19-0.92; P=.028). IGT was evident in 24.6% and 20.3 on conservative vs. replacement therapy, with no statistically significant difference. IFG (ADA criteria) was 19.75 vs. 9.24% in conservative vs. replacement therapy, with a statistically significant difference. OGTT is suggested for all CKD patients since it is able to detect the full range of unknown dysglycaemias, which avoids underdiagnoses and favours performing treatments to prevent progression in DM risk groups (IFG and/or IGT). It also aids in the selection of the most appropriate medication for transplantation or treatment initiation in new cases of undiagnosed DM to decrease morbidity and mortality.

The purpose of this study was to investigate the precise pattern of stroke volume (SV) response during exercise in patients with chronic heart failure (CHF) compared with age-matched controls. Fourteen patients with CHF and 7 controls performed symptom-limited bicycle exercise testing with respiratory gas exchange measurement. Patients were classified into group A (n = 7) with peak VO2 ≥ 18.0 mL/kg/minute and group B (n = 7) with peak VO2 < 18.0 mL/kg/ minute. SV and cardiac output (CO) were continuously measured during exercise using a novel thoracic impedance method (Physioflow). CO and SV were lower in the group B patients than those in controls at peak exercise [CO: 11.3 ± 1.0 (SE) versus 15.6 ± 0.9 L/minute, P < 0.05, SV: 89 ± 6 versus 110 ± 6 mL, P < 0.05]. SV reached its peak levels during submaximal exercise and remained close to the peak value until peak exercise in 6 of 7 group B patients (86%). On the other hand, it progressively increased until peak exercise in 6 of 7 controls (86%) and 5 of 7 group A patients (71%). In all subjects, CO at peak exercise was more closely correlated with SV at peak exercise (r = 0.86, P < 0.001) than with peak heart rate (r = 0.69, P < 0.001). CHF patients with impaired exercise capacity had attenuated increment of CO during exercise, and SV reached its peak levels during submaximal exercise.

Background/Aims Patients with chronic hepatitis C (CHC) often have increased liver iron, a condition associated with reduced sustained response to antiviral therapy, more rapid progression to cirrhosis, and development of hepatocellular carcinoma. The hepatic hormone hepcidin is the major regulator of iron metabolism and inhibits iron absorption and recycling from erythrophagocytosis. Hepcidin decrease is a possible pathophysiological mechanism of iron overload in CHC, but studies in humans have been hampered so far by the lack of reliable quantitative assays for the 25-amino acid bioactive peptide in serum (s-hepcidin). Methods Using a recently validated immunoassay, we measured s-hepcidin levels in 81 untreated CHC patients and 57 controls with rigorous definition of normal iron status. All CHC patients underwent liver biopsy with histological iron score. Results S-hepcidin was significantly lower in CHC patients than in controls (geometric means with 95% confidence intervals: 33.7, 21.5–52.9 vs. 90.9, 76.1–108.4 ng/mL, respectively; p < 0.001). In CHC patients, s-hepcidin significantly correlated with serum ferritin and histological total iron score, but not with s-interleukin-6. After stratification for ferritin quartiles, s-hepcidin increased significantly across quartiles in both controls and CHC patients (chi for trend, p < 0.001). However, in CHC patients, s-hepcidin was significantly lower than in controls for each corresponding quartile (analysis of variance, p < 0.001). Conclusions These results, together with very recent studies in animal and cellular models, indicate that although hepcidin regulation by iron stores is maintained in CHC, the suppression of this hormone by hepatitis C virus is likely an important factor in liver iron accumulation in this condition.

Among 2338 chronic hepatitis B patients followed during 2006-2013 in the Chronic Hepatitis Cohort Study, 78% had ≥1 alanine aminotransferase and 37% had ≥1 hepatitis B virus DNA level assessed annually. Among cirrhotic patients, 46% never had hepatic imaging. Patients in this cohort were insufficiently monitored for disease activity and hepatocellular carcinoma.

Patient beliefs about their illness can motivate behaviors consistent with good disease management. Perceived high-quality chronic care would be expected to increase likelihood of having such beliefs. Associations between perceived quality of chronic care and illness representations, and associations between patient centeredness and illness representations were assessed among persons with diabetes. A mail survey of diabetic patients visiting a multispecialty physician network serving urban and suburban populations in a large midwestern city was conducted. The Patient Assessment of Chronic Illness Care-5A questionnaire was used to assess perceived chronic care quality and patient centeredness. The Brief Illness Perception Questionnaire was used to assess illness representations. Of 500 mailed surveys, 89 completed surveys were returned. The sample consisted mostly of retirees (61%), Whites (81%), and women (60%). Higher perceived chronic care quality was associated with better disease understanding of diabetes (0.24, p = .05). Patients reporting higher patient centeredness (or lower patient-centeredness scores) indicated better disease understanding (-0.26, p = .04) and those reporting higher patient centeredness (or lower patient-centeredness scores) perceived less impact of illness (0.29, p = .02). Chronic care quality as defined in the Chronic Care Model and consistency of chronic care with patient expectations (patient centeredness) was associated with illness representations favorable for good self-care management.

Objective: Patients with comorbid chronic conditions may prioritize some conditions over others; however, our understanding of factors influencing those prioritizations is limited. In this study, we sought to identify and elaborate a range of factors that influence how and why patients with comorbid chronic conditions prioritize their conditions. Methods: We conducted semi-structured, one-on-one interviews with 33 patients with comorbidities recruited from a single Veterans Health Administration Medical Center. Findings: The diverse factors influencing condition prioritization reflected three overarching themes: (1) the perceived role of a condition in the body, (2) self-management tasks, and (3) pain. In addition to these themes, participants described the rankings that they believed their healthcare providers would assign to their conditions as an influencing factor, although few reported having shared their priorities or explicitly talking with providers about the importance of their conditions. Conclusion: Studies that advance understanding of how and why patients prioritize their various conditions are essential to providing care that is patient-centered, reflecting what matters most to the individual while improving their health. This analysis informs guideline development efforts for the care of patients with comorbid chronic conditions as well as the creation of tools to promote patient–provider communication regarding the importance placed on different conditions.

Concerning a revision about the mutual influence between the diabetes, the diabetic and his family, the author reviews the literature about the psychosocial area of the Family Physician content's work. It is also confirmed the high prevalency of the chronic disease and the importance of the family ecosystem, not only as support but also as problem to the bearing person of such type of disease. Studies of chronic disease indicate that family dysfunction is associated with poor health outcomes. The areas which more and better have been studied in this scope are reviewed. Thus, having as backdrop the diabetes management, the family's diabetic influence in general is reviewed, as well as the parental attitudes, the family organization and the family life events. Finally, the health care team role is reviewed and particulary the role of the family physician in the management of this type of patients. It is pointed out, as example of the Family Medicine specific contribution, the improving cooperation with medical treatment from the diabetic.

Chronic liver diseases (CLD) alter the kinetics of drugs. Despite dosage adjustment is based on Child-Pugh scores, there are no available recommendations and/or algorithms of reference to facilitate dosage regimens. A literature review about dose adjustment of the drugs from the hospital guide -which are included in the list of the WHO recommended drugs to be avoided or used with caution in patients with liver disease- was carried out. The therapeutic novelties from the last few years were also included. In order to do so, the summary of product characteristics (SPC), the database DrugDex-Micromedex, the WHO recommendations and the review articles from the last 10 years in Medline were reviewed. Moreover, the kinetic parameters of each drug were calculated with the aim of establishing a theoretical recommendation based on the proposal of Delcò and Huet. Recommendations for 186 drugs are presented according to the SPC (49.5%), DrugDex-Micromedex (26.3%) and WHO (18.8%) indications; six recommendations were based on specific publications; the theoretical recommendation based on pharmacokinetic parameters was proposed in four drugs. The final recommendations for clinical management were: dosage modification (26.9%), hepatic/analytical monitoring of the patient (8.6%), contraindication (18.8%), use with caution (19.3%) and no adjustment required (26.3%). In this review, specific recommendations for the practical management of patients with chronic liver disease are presented. It has been elaborated through a synthesis of the published bibliography and completed by following a theoretical methodology.

Objective The current study is an innovative exploratory investigation, aiming at identifying differences in personality profiles within Fibromyalgia Syndrome (FMS) and Chronic Fatigue Syndrome (CFS) patients. Method In total, 344 participants (309 female, 35 male) reported suffering from FMS and/or CFS and consented to participate in the study. Participants were recruited at an Israeli FM/CFS patient meeting held in May 2013, and through an announcement posted on several social networks. Participants were asked to complete a research questionnaire, which included FMS criteria and severity scales, and measures of personality, emotional functioning, positivity, social support and subjective assessment of general health. In total, 204 participants completed the research questionnaire (40.7% attrition rate). Results A cluster analysis produced two distinct clusters, which differed significantly on psychological variables, but did not differ on demographic variables or illness severity. As compared to cluster number 2 (N = 107), participants classified into cluster number 1 (N = 97) showed a less adaptive pattern, with higher levels of Harm Avoidance and Alexithymia; higher prevalence of Type D personality; and lower levels of Persistence (PS), Reward dependence (RD), Cooperation, Self-directedness (SD), social support and positivity. Conclusion The significant pattern of results indicates at least two distinct personality profiles of FM and CFS patients. Findings from this research may help improve the evaluation and treatment of FM and CFS patients, based on each patient’s unique needs, psychological resources and weaknesses, as proposed by the current trend of personalized medicine.

The prevalence of sleep disorders during childhood has been estimated to range from 25 to 43 %. The aim of this review is to determine the prevalence of sleep disorders and possible associations with chronic kidney disease (CKD)-related factors and health-related quality of life (HRQOL) in children with CKD. An electronic systematic literature search for sleep disorders in children with CKD in Pubmed, Embase and the Cochrane Library Databases identified seven relevant articles for review, all of which reported an increased prevalence of sleep disorders in children with CKD. Five studies included children with CKD undergoing dialysis, and two studies included only non-dialysis patients. In all studies the presence of sleep disturbances was assessed by questionnaires; only one study compared the results of a validated questionnaire with laboratory-based polysomnography. The prevalence of any sleep disorder ranged from 77 to 85 % in dialysis patients, to 32-50 % in transplanted patients and 40-50 % in non-dialysis patients. The most commonly studied disorder was restless legs syndrome, which presented at a prevalence of 10-35 %. Three studies showed significant associations between presence of sleep disorders and HRQOL. We found consistent evidence of an increased prevalence of sleep disturbances in children with CKD, and these seemed to play a critical role in HRQOL.

Over the past 20 years, exposure to mycotoxin producing mold has been recognized as a significant health risk. Scientific literature has demonstrated mycotoxins as possible causes of human disease in water-damaged buildings (WDB). This study was conducted to determine if selected mycotoxins could be identified in human urine from patients suffering from chronic fatigue syndrome (CFS). Patients (n = 112) with a prior diagnosis of CFS were evaluated for mold exposure and the presence of mycotoxins in their urine. Urine was tested for aflatoxins (AT), ochratoxin A (OTA) and macrocyclic trichothecenes (MT) using Enzyme Linked Immunosorbent Assays (ELISA). Urine specimens from 104 of 112 patients (93%) were positive for at least one mycotoxin (one in the equivocal range). Almost 30% of the cases had more than one mycotoxin present. OTA was the most prevalent mycotoxin detected (83%) with MT as the next most common (44%). Exposure histories indicated current and/or past exposure to WDB in over 90% of cases. Environmental testing was performed in the WDB from a subset of these patients. This testing revealed the presence of potentially mycotoxin producing mold species and mycotoxins in the environment of the WDB. Prior testing in a healthy control population with no history of exposure to a WDB or moldy environment (n = 55) by the same laboratory, utilizing the same methods, revealed no positive cases at the limits of detection.

Febuxostat is a nonpurine xanthine oxidase (XO) inhibitor, which recently received marketing approval. However, information regarding the experience with this agent among advanced chronic kidney disease (CKD) patients is limited. In the current study, we investigated the effects of oral febuxostat in patients with advanced CKD with asymptomatic hyperuricemia. We demonstrated, for the first time, that not only the serum levels of uric acid (UA) but also those of 8-hydroxydeoxyguanosine, an oxidative stress marker, were significantly reduced after six months of febuxostat treatment, with no adverse events. These results encouraged us to pursue further investigations regarding the clinical impact of lowering the serum UA levels with febuxostat in advanced CKD patients in terms of concomitantly reducing oxidative stress via the blockade of XO. More detailed studies with a larger number of subjects and assessments of the effects of multiple factors affecting hyperuricemia, such as age, sex, and dietary habits, would shed light on the therapeutic challenges of treating asymptomatic hyperuricemia in patients with various stages of CKD.

Venetoclax is the first BCL2 inhibitor to enter routine clinical practice. It is an orally bioavailable small molecule that binds BCL2 very specifically. Acting as a pharmacological mimic of the proteins that initiate apoptosis (a so-called BH3-mimetic), venetoclax rapidly induces apoptosis in chronic lymphocytic leukemia (CLL) cells which express high levels of BCL2 and rely on it to maintain their survival. As a single agent, daily venetoclax treatment induced durable responses in 79% of patients with relapsed or refractory CLL or small lymphocytic lymphoma in a Phase 1 study, including complete remissions in 20% of patients. Its use was approved by the FDA in April 2016 for patients with previously treated del(17p) CLL on the basis of a single arm Phase 2 trial demonstrating a 79% response rate and an estimated 1 year progression-free survival of 72% with 400mg/day continuous therapy. This review focuses on venetoclax, its mechanism-of-action, pharmacology and clinical trial data, and seeks to place it in the context of rapid advances in therapy for patients with relapsed CLL, especially those with del(17p) CLL.

Pulmonary thromboendarterectomy is the treatment of choice in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, specific medical treatment of pulmonary hypertension (PH) can be an alternative or play a complementary role to surgery. Thus, in patients unsuitable for surgery due to distal thrombotic obstruction, residual or persistent PH after surgery or very severe PH and a high-risk hemodynamic profile, medical treatment may improve their clinical course and the outcome of thromboendarterectomy. Patients with distal obstruction in the pulmonary tree and those with residual PH after surgery show clinical and hemodynamic deterioration due to progression of the pulmonary vascular disease in the smallcaliber arterioles. Conventional treatment with diuretics, anticoagulants and oxygen therapy has been demonstrated to have little effectiveness. In the last decade, numerous drugs have been developed for the treatment of PH: prostacyclin analogs, endothelin receptor antagonists, and phosphodiesterase-5 inhibitors acting principally in vascular remodelling of small-caliber arterioles. Although evidence of the effectiveness of these drugs in PH and the histological similarity of small-vessel vasculopathy in CTEPH to that of other forms of PH provide the main rationale for the use of these drugs in patients with CTEPH, the evidence from clinical trials is still limited.

Mn vacancy defect and grain size are shown to modify the magnetic phase diagram of MnSi significantly, especially near the critical regime of A-phase (skyrmion lattice) formation and the helimagnetic phase transition. Crystals grown using controlled nonstoichiometric initial precursors creates both grain boundaries and intrinsic Mn vacancy defect of various levels in MnSi. The results of combined transport, specific heat, and AC spin susceptibility measurements are compared for MnSi single crystal samples of various manganese deficiency levels and grain sizes. The finite-size effect and Mn vacancy level dependent helical phase transition temperature T(c) have been identified and verified. The stability of A-phase in H-T phase space has been examined through AC spin susceptibility data analysis.

Patients with chronic kidney disease (CKD), including those with end-stage renal disease, treated with dialysis, or renal transplant recipients have an increased risk for cardiovascular disease (CVD) morbidity and mortality. Dyslipidemia, often present in this patient population, is an important risk factor for CVD development. Specific quantitative and qualitative changes are seen at different stages of renal impairment and are associated with the degree of glomerular filtration rate declining. Patients with non-dialysis-dependent CKD have low high-density lipoproteins (HDL), normal or low total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol, increased triglycerides as well as increased apolipoprotein B (apoB), lipoprotein(a) (Lp (a)), intermediate- and very-low-density lipoprotein (IDL, VLDL; “remnant particles”), and small dense LDL particles. In patients with nephrotic syndrome lipid profile is more atherogenic with increased TC, LDL, and triglycerides. Lipid profile in hemodialysis (HD) patients is usually similar to that in non-dialysis-dependent CKD patients. Patients on peritoneal dialysis (PD) have more altered dyslipidemia compared to HD patients, which is more atherogenic in nature. These differences may be attributed to PD per se but may also be associated with the selection of dialytic modality. In renal transplant recipients, TC, LDL, VLDL, and triglycerides are elevated, whereas HDL is significantly reduced. Many factors can influence post-transplant dyslipidemia including immunosuppressive agents. This patient population is obviously at high risk; hence, prompt diagnosis and management are required to improve their clinical outcomes. Various studies have shown statins to be effective in the cardiovascular risk reduction in patients with mild-to-moderate CKD as well as in renal transplant recipients. However, according to recent clinical randomized controlled trials (4D, A Study to Evaluate the Use of Rosuvastatin in Subjects on

Portal-systemic encephalopathy (PSE) is classified as type B hepatic encephalopathy. Portal-systemic shunting rather than liver dysfunction is the main cause of PSE in chronic hepatic schistosomiasis japonicum (HSJ) patients. Owing to lack of detectable evidence of intrinsic liver disease, chronic HSJ patients with PSE are frequently clinically undetected or misdiagnosed, especially chronic HSJ patients with covert PSE (subclinical encephalopathy). In this study, we investigated whether magnetic resonance spectroscopy (MRS) could be a useful tool for diagnosing PSE in chronic HSJ patients. Magnetic resonance (MR) T1-weighted imaging, diffusion-weighted imaging, and MRS were performed in 41 chronic HSJ patients with suspected PSE and in 21 age-matched controls. The T1 signal intensity index (T1SI) and apparent diffusion coefficient (ADC) value were obtained in the Globus pallidus. Liver function was also investigated via serum ammonia and liver function tests. Higher T1SI and ADC values, increased lactate and glutamine levels, and decreased myo-inositol were found in the bilateral Globus pallidus in chronic HSJ patients with PSE. No significantly abnormal serum ammonia or liver function tests were observed in chronic HSJ patients with PSE. On the basis of these findings, we propose a diagnostic procedure for PSE in chronic HSJ patients. This study reveals that MRS can be useful for diagnosing PSE in chronic HSJ patients. PMID:27977668

Higher T1SI and ADC values, increased lactate and glutamine levels, and decreased myo-inositol were found in the bilateral Globus pallidus in chronic HSJ patients with PSE. No significantly abnormal serum ammonia or liver function tests were observed in chronic HSJ patients with PSE. On the basis of these findings, we propose a diagnostic procedure for PSE in chronic HSJ patients. This study reveals that MRS can be useful for diagnosing PSE in chronic HSJ patients.

Behavioral studies in rodents and humans have demonstrated deficits of spatial memory and orientation in bilateral vestibular failure (BVF). Our aim was to explore the functional consequences of chronic vestibular failure on different cognitive domains including spatial as well as non-spatial cognitive abilities. Sixteen patients with a unilateral vestibular failure (UVF), 18 patients with a BVF, and 17 healthy controls (HC) participated in the study. To assess the cognitive domains of short-term memory, executive function, processing speed and visuospatial abilities the following tests were used: Theory of Visual Attention (TVA), TAP Alertness and Visual Scanning, the Stroop Color-Word, and the Corsi Block Tapping Test. The cognitive scores were correlated with the degree of vestibular dysfunction and the duration of the disease, respectively. Groups did not differ significantly in age, sex, or handedness. BVF patients were significantly impaired in all of the examined cognitive domains but not in all tests of the particular domain, whereas UVF patients exhibited significant impairments in their visuospatial abilities and in one of the two processing speed tasks when compared independently with HC. The degree of vestibular dysfunction significantly correlated with some of the cognitive scores. Neither the side of the lesion nor the duration of disease influenced cognitive performance. The results demonstrate that vestibular failure can lead to cognitive impairments beyond the spatial navigation deficits described earlier. These cognitive impairments are more significant in BVF patients, suggesting that the input from one labyrinth which is distributed into bilateral vestibular circuits is sufficient to maintain most of the cognitive functions. These results raise the question whether BVF patients may profit from specific cognitive training in addition to physiotherapy.

The aim of this work was the determination of the state of local immunity in periodontal complex in patients with chronic generalized periodontitis (CGP). 96 individuals were examined (mean age 43.6+/-1.2 years). All the patients were divided into 2 groups: basic group with CGP patients (76 persons) and comparative group - individuals with intact periodontium (20 persons). To evaluate local immunity in dentogingival fluids the determination of concentrations of IgG, IgM, and IgA immunoglobulins has been used, as well as TNF-alpha, IL-1, IL-6, IL-8, INF-gamma, IL-1ra, IL-10, and IL-4 cytokines, and also factors controlling the state of bone tissue, namely, osteoprotegerine (OPG), and RANK-ligand. In gingival fluid of CGP patients the increase in both pro-, and anti-inflammatory mediators with indication to Th2-deviation (decrease of INF-gamma level and elevation of IL-4 level) was observed. CGP patients exhibited in their periodontal complex marked increase of IgG, IgM, and IgA concentrations that apparently evidenced to the consequence of local polyclonal activation of B-lymphocytes. Gingival fluid of CGP patients showed the elevation of RANKL, TNF-alpha, and IL-1 levels, and the decrease in OPG concentration that could be the reason for osteoclast activation and subsequent destruction of bone tissue. In case of CGP in the zone of periodontium developed

Introduction Healthcare management is oriented toward single diseases, yet multimorbidity is nevertheless the rule and there is a tendency for certain diseases to occur in clusters. This study sought to identify comorbidity patterns in patients with chronic diseases, by reference to number of comorbidities, age and sex, in a population receiving medical care from 129 general practitioners in Spain, in 2007. Methods A cross-sectional study was conducted in a health-area setting of the Madrid Autonomous Region (Comunidad Autónoma), covering a population of 198,670 individuals aged over 14 years. Multiple correspondences were analyzed to identify the clustering patterns of the conditions targeted. Results Forty-two percent (95% confidence interval [CI]: 41.8–42.2) of the registered population had at least one chronic condition. In all, 24.5% (95% CI: 24.3–24.6) of the population presented with multimorbidity. In the correspondence analysis, 98.3% of the total information was accounted for by three dimensions. The following four, age- and sex-related comorbidity patterns were identified: pattern B, showing a high comorbidity rate; pattern C, showing a low comorbidity rate; and two patterns, A and D, showing intermediate comorbidity rates. Conclusions Four comorbidity patterns could be identified which grouped diseases as follows: one showing diseases with a high comorbidity burden; one showing diseases with a low comorbidity burden; and two showing diseases with an intermediate comorbidity burden.

For social, cultural and historical motives alcohol (ethanol or isopenthanol) is considered to be just a beverage rather than a liquor. However, from a pharmatherapeutic point of view alcohol is a depressor of the central nervous system. The effects of alcohol consumption can range from raised loquacity to drunkenness, loss of consciousness and death as a result of insufficient respiration. Probably the most frequent pharmacological interaction is the combination of alcohol with other depressors of the central nervous system which increases the depression even further. Some medicaments which more frequently produce an interaction are antihistamines, analgesics, antidepressants and medicaments for coughs, common cold and influenza. Paracetamol or acetaminophen is an analgesic medicament similar to acetylsalicylic acid lacking anticoagulatory properties and gastric irritation. However, its major drawback is hepatic toxicity as a result of a toxic metabolite produced in the liver by cytochrome P-450, principally cytochrome CYP2E1, which is detoxified under normal conditions by hepatic glutathione. Ethanol is also detoxified by CYP2E1, which is an inducer of ethanol such that chronic ingestion increases the level of this enzyme. When the ingestion of alcohol is stopped, CYP2E1 is greatly increased and only metabolises the paracetamol giving rise to high quantities of hepatotoxic metabolites so that the hepatic glutathione is unable to detoxify resulting in irreversible hepatic damage. Therefore for odontologists it is important that in chronic alcoholic patients the consumption of alcohol should not be suspended on prescribing paracetamol.

Comprehensive disease management programmes for chronic disease aim to improve patient outcomes and reduce health-care utilization. Readmission rates are often used as an outcome measure of effectiveness. This study aimed to document readmission rates, and risk for early and late readmission, for patients discharged from the Royal Melbourne Hospital with a disease diagnosis of chronic heart failure (CHF), chronic obstructive pulmonary disease (COPD) or diabetes mellitus compared to those with other general medical conditions. Eighty five (8.6%) of patients were readmitted within 28 days and 183 (20.8%) were readmitted between 29 and 180 days. No risk factors for early readmission were identified. Patients with a primary disease diagnosis of CHF and COPD are at increased risk of late readmissions (29-180 days).

21 female patients suffering from chronic tension headache received 10 sessions of upper body massage consisting of deep tissue techniques in addition to softer techniques in the beginning. When found, trigger points were carefully and forcefully massaged. The range of cervical movements, surface ENMG on mm. frontalis and trapezius, visual analogue scale (VAS) and Finnish Pain Questionnaire (FPQ), and the incidence of neck pain during a two week period before and after the treatment, and at 3 and 6 months during the follow-up period together with Beck depression inventory were taken for evaluation and follow-up. The range of movement in all directions increased, and FPQ, VAS and the number of days with neck pain decreased significantly. There was a significant change in ENMG on the frontalis muscle whereas changes in trapezius remained insignificant. Beck inventory showed an improvement after the treatment. This study confirmed clinical and physiological effects of massage.
Background Chronic cough patients are rendered therapies for gastro-esophageal reflux (GERD), upper airway cough syndrome (UACS) and cough-variant asthma (CVA) with varying benefit. Idiopathic or unexplained cough has emerged as an important clinical entity in both primary care and subspecialty clinics. Recent evidence points to a link between chronic cough and untreated obstructive sleep apnea (OSA). Methods A prospective observational study was done to evaluate the effect of OSA therapy in patients with chronic cough. Patients enrolled into the study underwent questionnaires to evaluate for GERD, UACS and CVA along with screening questionnaires for OSA and daytime sleepiness. The Leicester cough questionnaire (LCQ) was done at baseline and during serial visits to evaluate cough intensity and was used as the primary outcome measure of the effect of CPAP therapy on chronic cough. Results Out of 37 patients enrolled into the study, only 28 patients had follow up LCQ scores available and therefore underwent analysis. 22/28 patients were suspected to have OSA based on abnormal STOP-BANG screening questionnaire scores and overnight oximetry abnormalities. Of these 19/28 patients had overnight attended polysomnography with definitive diagnosis of OSA yielding a 68% prevalence of OSA in our chronic cough population. Chronic cough patients treated for OSA tended to be older with a significantly higher BMI than chronic cough patients without OSA. Significant improvement of LCQ scores occurred with CPAP therapy for OSA in chronic cough patients. Conclusion OSA is significantly prevalent in chronic cough patients. Subjects with chronic cough and OSA tend to be older and obese. Treatment of OSA in chronic cough patients yields significant improvement in their health status. PMID:23845135

Chronic itch is a common symptom in haemodialysis (HD) patients, which is often underestimated. The aim of this cross-sectional study was to investigate the prevalence and factors associated with chronic itch in HD patients. A total of 860 HD patients from a randomly selected cluster-sample of patients attending dialysis units in Germany were included. The patients' mean?±?SD age was 67.2?±?13.5 years, 57.2% were male. The point prevalence of chronic itch was 25.2% (95% CI 22.4-28.1), 12-month prevalence was 27.2% (95% CI 24.1-30.3) and lifetime prevalence was 35.2% (95% CI 31.9-38.3). Chronic itch was significantly less prevalent in patients with secondary glomerulonephritis as primary renal disease. A history of dry skin, eczema, and age 70 years were significantly associated with chronic itch. General health status and quality of life were significantly more impaired in subjects with chronic itch. This is the first representative cross-sectional study using a precise definition of chronic itch and using different prevalence estimates of chronic itch in HD patients. It demonstrates that chronic itch is a long-lasting burden significantly impairing patients' health.

Chronic diarrhea with a 35 kg weight loss (75 kg to 40 kg) occurred during 2 years in an alcoholic patient was diagnosed with Isospora belli infection in the Republic of Korea. The patient, a 70-year old Korean male, had been a heavy drinker for more than 30 years. He was admitted to the Seoul National University Hospital because of long-standing diarrhea and severe weight loss. He had an increased white blood cell (WBC) count with high peripheral blood eosinophilia (36.8-39.9%) and lowered protein and albumin levels but without any evidence of immunosuppression. A parasitic infection was suspected and fecal examination was repeated 3 times with negative results. Peroral endoscopy with mural biopsy was performed in the upper jejunum. The biopsy specimens revealed villous atrophy with loss of villi together with various life cycle stages of I. belli, including trophozoites, schizonts, merozoites, macrogamonts, and microgamonts. The patient was treated successfully with oral doses of trimethoprim 160-320 mg and sulfamethoxazole 800-1,600 mg daily for 4 weeks. A follow-up evaluation at 2.5 years later revealed marked improvement of body weight (68 kg), increased protein and albumin levels, and normal WBC count with low eosinophils (3.1%). This is the first clinical case of isoporiasis with demonstration of various parasitic stages in the Republic of Korea. PMID:23710089

Sinusitis is a cause of significant morbidity, substantial healthcare costs, and negative effects on quality of life. The primary objective of this study is to characterize the previously unknown lipid profile of sinonasal mucosa from patients with chronic rhinosinusitis (CRS) and from controls. Sinus mucosa samples were analyzed from 9 CRS patients with concomitant nasal polyps, 11 CRS patients without polyps, and 12 controls. Ten lone polyp samples were also analyzed. Samples were subjected to a modified Bligh/Dyer lipid extraction, then high performance thin layer chromatography (HPTLC), combined gas chromatography/electron impact-mass spectrometry (GC/EI-MS), and flow-injection/electrospray ionization-tandem mass spectrometry (FI/ESI-MS/MS). Data was analyzed for identification and profiling of major components. HPTLC revealed an array of species reflecting the lipid complexity of the samples. GC/EI-MS revealed cholesterol and several fatty acids. FI/ESI-MSMS revealed numerous lipid species, namely a host of phosphatidylcholines, phosphatidylethanolamines, ceramides and cholesteryl esters, but no detectable amounts of phosphatidyinositols or sulfated lipids. These results are a first step to uncover unique molecular biomarkers in CRS. PMID:25588779

Constipation is a common functional gastrointestinal disorder, with prevalence in the general population of approximately 20%. In the elderly population the incidence of constipation is higher compared to the younger population, with elderly females suffering more often from severe constipation. Treatment options for chronic constipation (CC) include stool softeners, fiber supplements, osmotic and stimulant laxatives, and the secretagogues lubiprostone and linaclotide. Understanding the underlying etiology of CC is necessary to determine the most appropriate therapeutic option. Therefore, it is important to distinguish from pelvic floor dysfunction (PFD), slow and normal transit constipation. Evaluation of a patient with CC includes basic blood work, rectal examination, and appropriate testing to evaluate for PFD and slow transit constipation when indicated. Pelvic floor rehabilitation or biofeedback is the treatment of choice for PFD, and its efficacy has been proven in clinical trials. Surgery is rarely indicated in CC and can only be considered in cases of slow transit constipation when PFD has been properly excluded. Other treatment options such as sacral nerve stimulation seem to be helpful in patients with urinary dysfunction. Botulinum toxin injection for PFD cannot be recommended at this time with the available evidence. CC in the elderly is common, and it has a significant impact on quality of life and the use of health care resources. In the elderly, it is imperative to identify the etiology of CC, and treatment should be based on the patient's overall clinical status and capabilities.

Diabetic ulcers and pressure ulcers represent a more frequent cause of chronic wounds in aging populations. It is estimated that approximately 15% of the diabetic population will develop diabetic ulcers during their life and over half of these patients develop an infection, often osteomyelitis, with 20% requiring amputation. The authors report a case of a 65-year-old woman affected by a post-traumatic loss of substance due to road accidents with soft tissue exposure (comprising muscle tendon) of the left knee combined with the fracture of the right fibula previously subjected to surgery and reconstruction of muscle tendon. The patient was affected by diabetes type II, hypertension, and ischemic heart disease. In 2008, she underwent a double bypass surgery and coronary angioplasty. Initially, the patient was treated with cycles of advanced dressings, with fibrinolytic ointments, hydrocolloid, and subsequently, when the bottom began granulated with fibrinolytic and idrocellulosa, Hydrofibra-Ag, and Ag-alginate, three times a week for 30 days. In the second step, the authors decided to treat the ulcer with the MATRIDERM system and auto skin graft. Following the first treatment, 7 days after the procedure, the authors found the reduction of the loss of substance until its complete closure. The wound’s infection was evaluated by a buffer negative confirmation performed every 2 weeks four times. We obtained decrease of limb edema and full functional rehabilitation. The skin appeared renovated, with volume restoration and an improvement of the texture. PMID:24020011

Although substantial evidence has established that microglia and astrocytes play a key role in the establishment and maintenance of persistent pain in animal models, the role of glial cells in human pain disorders remains unknown. Here, using the novel technology of integrated positron emission tomography-magnetic resonance imaging and the recently developed radioligand (11)C-PBR28, we show increased brain levels of the translocator protein (TSPO), a marker of glial activation, in patients with chronic low back pain. As the Ala147Thr polymorphism in the TSPO gene affects binding affinity for (11)C-PBR28, nine patient-control pairs were identified from a larger sample of subjects screened and genotyped, and compared in a matched-pairs design, in which each patient was matched to a TSPO polymorphism-, age- and sex-matched control subject (seven Ala/Ala and two Ala/Thr, five males and four females in each group; median age difference: 1 year; age range: 29-63 for patients and 28-65 for controls). Standardized uptake values normalized to whole brain were significantly higher in patients than controls in multiple brain regions, including thalamus and the putative somatosensory representations of the lumbar spine and leg. The thalamic levels of TSPO were negatively correlated with clinical pain and circulating levels of the proinflammatory citokine interleukin-6, suggesting that TSPO expression exerts pain-protective/anti-inflammatory effects in humans, as predicted by animal studies. Given the putative role of activated glia in the establishment and or maintenance of persistent pain, the present findings offer clinical implications that may serve to guide future studies of the pathophysiology and management of a variety of persistent pain conditions.

The audiological results of 46 patients (m/f 27/19, mean age; 57.4 +/- 11.1) with chronic renal failure (CRF) undergoing dialysis were compared with those of an age- and gender-matched control group (n = 25). Mean pure tone average from 0.5 to 8 kHz was about 15 dB higher in CRF patients than in control subjects. The ABR parameters of the test group were then contrasted with those recorded in a second control group (n = 47, m/f 26/21, mean age: 56.1 +/- 11.4) matched by age, gender and degree of hearing loss (HL). After assessing the normality of the groups by the usual criteria, using the data of a sample of normal young adults, the ABR were found to be abnormal in 23.9% of the controls and in the 39.13% of the CRF patients. Wave V, I-III, III-V and I-V delays were significantly shorter in the females of the control group; in the CRF group, only the V and the I-V delays were shorter in females. The only age-dependent effect was found in the CRF sample, in which older patients had significantly longer I-III IPLD. The degree of HL influenced the latency of the waves in both groups but only the I-V IPLD was longer in CRF patients with pronounced high tone loss. The most distinguishing feature between the effects of CRF plus ageing and those of normal ageing was the lengthening of the I-III IPLD in the test group. This finding is likely to reflect a subclinical disorder of the VIII nerve function that is a part of the axonal uremic neuropathy.

Thrombocytopenia in patients with chronic hepatitis C virus (HCV) infection is a major problem. The pathophysiology is multifactorial, with auto-immunogenicity, direct bone marrow suppression, hypersplenism, decreased production of thrombopoietin and therapeutic adverse effect all contributing to thrombocytopenia in different measures. The greatest challenge in the care of chronic HCV patients with thrombocytopenia is the difficulty in initiating or maintaining IFN containing anti-viral therapy. Although at present, it is possible to avoid this challenge with the use of the sole Direct Antiviral Agents (DAAs) as the primary treatment modality, thrombocytopenia remains of particular interest, especially in cases of advanced liver disease. The increased risk of bleeding with thrombocytopenia may also impede the initiation and maintenance of different invasive diagnostic and therapeutic procedures. While eradication of HCV infection itself is the most practical strategy for the remission of thrombocytopenia, various pharmacological and non-pharmacological therapeutic options, which vary in their effectiveness and adverse effect profiles, are available. Sustained increase in platelet count is seen with splenectomy and splenic artery embolization, in contrast to only transient rise with platelet transfusion. However, their routine use is limited by complications. Different thrombopoietin analogues have been tried. The use of synthetic thrombopoietins, such as recombinant human TPO and pegylated recombinant human megakaryocyte growth and development factor (PEG-rHuMDGF), has been hampered by the development of neutralizing antibodies. Thrombopoietin-mimetic agents, in particular, eltrombopag and romiplostim, have been shown to be safe and effective for HCV-related thrombocytopenia in various studies, and they increase platelet count without eliciting any immunogenicity Other treatment modalities including newer TPO analogues-AMG-51, PEG-TPOmp and AKR-501, recombinant

Introduction Chronic Kidney Disease (CKD) is a major and globally increasing health problem in the general population arising from a spectrum of diseases. Majority of the patients die even before reaching End Stage Renal Disease (ESRD) due to cardiovascular complications which arise due to altered lipoprotein compositions. Aim Present study was aimed at evaluating the serum lipid profile in CKD patients and to find the pattern of its alteration in both haemodialyzed and conservatively treated CKD patients. Materials and Methods Seventy one randomly selected CKD patients attending a tertiary care hospital of Assam during one year of time frame (40 haemodialyzed and 31 conservatively treated) along with 50 apparently healthy controls were included in the study. Test for serum lipid profile, urea creatinine, FBS, PPBS, total protein and albumin were carried out in all the cases and controls. The results were analyzed and compared with the controls using Microsoft Excel software. Results Triglyceride Level (TGL) of CKD group 157.88±61.82, controls 96.98±37.52, Very Low Density Lipoprotein (VLDL) of CKD group 31.58±12.36, controls 19.39±7.50 was marginally elevated and High Density Lipoprotein (HDL) of CKD group 33.40±9.06, controls 45.95±10.35 was significantly reduced in the patient group as compared to the controls and the results were statistically highly significant with p-value<0.001. Total cholesterol (CKD group 128.2±53.57, controls 142.53±31.44) and LDL (CKD group 63.23±46.47, controls 77.35±26.81) were lower in the patient group as compared to the controls, however the difference was statistically not significant (p value 0.09 and 0.059 respectively). There was no statistically significant difference of lipid profile between hemodialyzed and conservatively treated CKD groups and there was no gender related variation of lipid profile too. Conclusion Increased TGL and reduced HDL, rather than increased total cholesterol and increased LDL are

In the second quarter 2011 the incidence of the symptoms "chronic dyspnea" among the patients in three specialist practices was determined by means of a self-developed questionnaire. 1286 anonymised questionnaires with full information could be evaluated. The proportion of the patients with a chronic dyspnea (inclusive "dyspnea and weakness feeling") in the practices amounted to between 15.3 and 57.7 %. An exclusive assessment of chronic dyspnea could be assigned to 10.4 to 31.4 % of the patients evaluated. From the view point of the treating physicians, the cause of the chronic dyspnea was sufficiently explained by the available information.

Background: The extracranial venous outflow routes in clinically defined multiple sclerosis (CDMS) have not previously been investigated. Methods: Sixty-five patients affected by CDMS, and 235 controls composed, respectively, of healthy subjects, healthy subjects older than CDMS patients, patients affected by other neurological diseases and older controls not affected by neurological diseases but scheduled for venography (HAV-C) blindly underwent a combined transcranial and extracranial colour-Doppler high-resolution examination (TCCS-ECD) aimed at detecting at least two of five parameters of anomalous venous outflow. According to the TCCS-ECD screening, patients and HAV-C further underwent selective venography of the azygous and jugular venous system with venous pressure measurement. Results: CDMS and TCCS-ECD venous outflow anomalies were dramatically associated (OR 43, 95% CI 29 to 65, p<0.0001). Subsequently, venography demonstrated in CDMS, and not in controls, the presence of multiple severe extracranial stenosis, affecting the principal cerebrospinal venous segments; this provides a picture of chronic cerebrospinal venous insufficiency (CCSVI) with four different patterns of distribution of stenosis and substitute circle. Moreover, relapsing-remitting and secondary progressive courses were associated with CCSVI patterns significantly different from those of primary progressive (p<0.0001). Finally, the pressure gradient measured across the venous stenosies was slightly but significantly higher. Conclusion: CDMS is strongly associated with CCSVI, a scenario that has not previously been described, characterised by abnormal venous haemodynamics determined by extracranial multiple venous strictures of unknown origin. The location of venous obstructions plays a key role in determining the clinical course of the disease. PMID:19060024

In the United States, hospitalization among patients with chronic hepatitis C virus (HCV) infection is high. The healthcare burden associated with hospitalization is not clearly known. We analysed data from the Chronic Hepatitis Cohort Study, an observational cohort of patients receiving care at four integrated healthcare systems, collected from 2006 to 2013 to determine all-cause hospitalization rates of patients with chronic HCV infection and the other health system patients. To compare the hospitalization rates, we selected two health system patients for each chronic HCV patient using their propensity score (PS). Propensity score matching was conducted by site, gender, race, age and household income to minimize differences attributable to these characteristics. We also compared primary reason for hospitalization between chronic HCV patients and the other health system patients. Overall, 10 131 patients with chronic HCV infection and 20 262 health system patients were selected from the 1 867 802 health system patients and were matched by PS. All-cause hospitalization rates were 27.4 (27.0-27.8) and 7.4 (7.2-7.5) per 100 persons-year (PY) for chronic HCV patients and for the other health system patients, respectively. Compared to health system patients, hospitalization rates were significantly higher by site, gender, age group, race and household income among chronic HCV patients (P < 0.001). Compared to health system patients, chronic HCV patients were more likely to be hospitalized from liver-related conditions (RR = 24.8, P < 0.001). Hence, patients with chronic HCV infection had approximately 3.7-fold higher all-cause hospitalization rate than other health system patients. These findings highlight the incremental costs and healthcare burden of patients with chronic HCV infection associated with hospitalization.

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

BACKGROUND: Chronic kidney disease (CKD) became a new epidemic of the twentieth and twenty-first centuries. Diabetic nephropathy is one of the leading causes of end-stage renal failure as a result of the diabetes epidemic worldwide. AIM: The aim of our study was to assess the prevalence of CKD in the Republic of Macedonia and its association with diabetes mellitus. MATERIALS AND METHODS: The study was a part of a study conducted in 2006 in terms of screening for early detection of kidney disease. It was a cross-sectional study based on a random sample of patients aged > 20, consecutively consulting their primary physician for any cause. Fifty physicians throughout the country were included in the study. A total of 2637 patients have been analyzed based on integrity data. GFR was estimated using corrected values of serum creatinine and calculating kidney function by the Cockroft & Gault formula, adjusted for body surface using the Gehan & George formula. Patients with estimated glomerular filtration rate (eGFR) less than 60 ml/min were considered as having CKD. Blood pressure, body weight, height, serum creatinine, glucose, hemoglobin, hematocrit, urinalysis and medical history for presence of cardiovascular diseases or diabetes were also assessed. RESULTS: The mean age of the subjects was 45.97 ± 16.55 SD and 17.97% were older than 60. Regarding gender, 44.14% were males. The prevalence of diabetes mellitus was 13.9%. Subjects with CKD (eGFR less than 60 ml/min) were 7.53% of the total. Subjects aged 60 or above, had 20 times higher risk of having CKD (eGFR less than 60 ml/min/1.73 m2). Out of the total group of subjects, 13.9% had diabetes mellitus and they had 3.13 times higher risk of having CKD stage 3-5 (eGFR less than 60 ml/min/1.73 m2) when compared to non-diabetics. The results showed that diabetes was significantly more associated with lower eGFR (less than 60 ml/min/1.73 m2) in younger subjects (age less than 60) compared to older ones (odds ratio 3

CC in the elderly is common, and it has a significant impact on quality of life and the use of health care resources. In the elderly, it is imperative to identify the etiology of CC, and treatment should be based on the patient’s overall clinical status and capabilities. PMID:26082622
The first patient with chronic paroxysmal hemicrania (CPH), a 41-year-old woman, first seen in 1961, was followed until an adequate treatment was found, 12 years later. Clinically, attack frequency and duration differed widely from the general pattern of cluster headache. Ocular variables, such as intraocular pressure and corneal indentation pulse amplitudes, also differed in our case (clear symptomatic side increment during attacks) and cluster headache. Pupil reactions to directly and indirectly acting sympathicomimetic drugs were also vastly different in our case and cluster headache: no signs of Horner s syndrome in our patient, while cluster headache exhibits a "Horner-like pattern." In cluster headache, there is a relative hypohidrosis in the forehead on the symptomatic side if body temperature is increased, and a clear hyperhidrosis on direct parasympathomimetic stimulation. This was not so in our case. Indomethacin was highly effective in our case, while "cluster headache drugs," such as ergotamine/sumatriptan, were ineffective. Indomethacin was inactive in cluster headache. Accordingly, our case seemed to differ decisively from cluster headache: CPH had been discovered.

The development of liver cirrhosis and portal hypertension (PH), one of its major complications, are structural and functional alterations of the liver, occurring in many patients with chronic liver diseases (CLD). Actually the progressive deposition of hepatic fibrosis has a key role in the prognosis of CLD patients. The subsequent development of PH leads to its major complications, such as ascites, hepatic encephalopathy, variceal bleeding and decompensation. Liver biopsy is still considered the reference standard for the assessment of hepatic fibrosis, whereas the measurement of hepatic vein pressure gradient is the standard to ascertain the presence of PH and upper endoscopy is the method of choice to detect the presence of oesophageal varices. However, several non-invasive tests, including elastographic techniques, are currently used to evaluate the severity of liver disease and predict its prognosis. More recently, the measurement of the spleen stiffness has become particularly attractive to assess, considering the relevant role accomplished by the spleen in splanchnic circulation in the course of liver cirrhosis and in the PH. Moreover, spleen stiffness as compared with liver stiffness better represents the dynamic changes occurring in the advanced stages of cirrhosis and shows higher diagnostic performance in detecting esophageal varices. The aim of this review is to provide an exhaustive overview of the actual role of spleen stiffness measurement as assessed by several elastographic techniques in evaluating both liver disease severity and the development of cirrhosis complications, such as PH and to highlight its potential and possible limitations.

Cardiovascular disorders are the most frequent cause of death (46-60%) among patients with advanced chronic renal failure (CRF), and on dialysis treatment. Uremic cardiomyopathy is the basic pathophysiologic substrate, whereas ischemic heart disease (IHD) and anemia are the most important contributing factors. Associated with well-know risk factors and specific disorders for terminal kidney failure and dialysis, the aforementioned factors instigate congestive heart failure (CHF). Suspected CHF is based on the anamnesis, clinical examination and ECG, while it is confirmed and defined more precisely on the basis of echocardiography and radiology examination. Biohumoral data (BNP, NT-proBNP) are not sufficiently reliable because of specific volemic fluctuation and reduced natural clearance. Therapy approach is similar to the one for the general population: ACEI, ARBs, β-blockers, inotropic drugs and diuretics. Hypervolemia and most of the related symptoms can be kept under control effectively by the isolated or ultrafiltation, in conjunction with dialysis, during the standard bicarbonate hemodialysis or hemodiafiltration. In the same respect peritoneal dialysis is efficient for the control of hypervolemia symptoms, mainly during the first years of its application and in case of the lower NYHA class (II°/III°). In general, heart support therapy, surgical interventions of the myocardium and valve replacement are rarely used in patients on dialysis, whereas revascularization procedures are beneficial for associated IHD. In selected cases the application of cardiac resynchronization and/or implantation of a cardioverter defibrillator are advisable.

Introduction This systematic review protocol aims to describe a meta-analysis to assess the effectiveness and safety of acupuncture therapy for patients with chronic urticaria. Methods and analysis We will electronically search the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, the Web of Science, Traditional Chinese Medicine, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Chinese Scientific Journal Database (VIP database) and Wan-Fang Database from their inception. Other sources will also be searched, including the reference lists of identified publications and conference proceedings. Any clinical randomised controlled trials related to acupuncture for treating chronic urticaria without restriction of publication status and languages will be included. Study selection, data extraction and assessment of study quality will be performed independently by 2 researchers. Data will be synthesised by either the fixed-effects or random-effects model according to a heterogeneity test. Improvement in pruritus and wheals will be assessed as the primary outcomes. Adverse events, quality of life and the recurrence rate after at least 3 months of the treatment will also be evaluated as secondary outcomes. RevMan V.5.2 statistical software will be used for meta-analysis, if possible. If it is not appropriate for a meta-analysis, then a descriptive analysis or a subgroup analysis will be conducted. The results will be expressed as a risk ratio for dichotomous data and mean difference (MD) or standardised MD for continuous data. Dissemination and ethics The protocol of this systematic review will be disseminated in a peer-reviewed journal and presented at relevant conferences. It is not necessary for a formal ethical approval because the data are not individualised. Trial registration number PROSPERO CRD42015015702. PMID:26338683

Human factors/ergonomics recognises work as embedded in and shaped by levels of social, physical and organisational context. This study investigates the contextual or macroergonomic factors present in the health-related work performed by patients. We performed a secondary content analysis of findings from three studies of the work of chronically ill patients and their informal caregivers. Our resulting consolidated macroergonomic patient work system model identified 17 factors across physical, social and organisational domains and household and community levels. These factors are illustrated with examples from the three studies and discussed as having positive, negative or varying effects on health and health behaviour. We present three brief case studies to illustrate how macroergonomic factors combine across domains and levels to shape performance in expected and unexpected ways. Findings demonstrate not only the importance of context for patients' health-related activities but also specific factors to consider in future research, design and policy efforts. Practitioner Summary: Health-related activities of patients are embedded in and shaped by levels of social, physical and organisational context. This paper combined findings from three studies to specify 17 contextual or macroergonomic factors in home- and community-based work systems of chronically ill patients. These factors have research, design and policy implications.

Summary Background Ponatinib has shown efficacy in patients with refractory chronic myeloid leukaemia (CML) and in those with CML with a Thr315Ile mutation. We aimed to investigate the activity and safety of ponatinib as first-line treatment for patients with chronic-phase CML. Methods We did a single-arm, phase 2 trial at MD Anderson Cancer Center in Houston, TX, USA. Between May 3, 2012, and Sept 24, 2013, we enrolled patients with early (<6 months) chronic-phase CML and treated them with oral ponatinib once a day. Patients enrolled before July 25, 2013, were given a starting dose of 45 mg per day; we lowered this due to tolerability issues and patients enrolled after this date were given a starting dose of 30 mg per day. After a warning by the US Food and Drug Administration (FDA) in Oct 6, 2013, for vascular complications with ponatinib, we started all patients on aspirin 81 mg daily and reduced the dose of ponatinib to 30 mg or 15 mg per day for all patients. The primary endpoint was the proportion of patients who achieved complete cytogenetic response by 6 months in the per-protocol population. This trial is registered with ClinicalTrials.gov, number NCT01570868. Findings We enrolled 51 patients. Median follow-up was 20.9 months (IQR 14.9–25.2). 43 patients were started on 45 mg ponatinib every day; eight patients were started on 30 mg per day. 43 (94%) of 46 evaluable patients achieved complete cytogenetic response at 6 months. Most frequent toxicities included skin-related effects (n=35; 69%) and elevated lipase (n=32; 63%). Cardiovascular events (mainly hypertension) occurred in 25 (49%) patients. Grade 3–4 myelosuppression occurred in 15 (29%) patients. Five (10%) patients developed cerebrovascular or vaso-occlusive disease. 43 (85%) patients needed treatment interruptions at some time and 45 (88%) needed dose reductions. The study was terminated June 18, 2014, at the recommendation of the FDA due to concern about the increased risk of thromboembolism

Introduction: Hypovitaminosis D is reported to be associated with several medical complications. Recent studies have reported a high worldwide prevalence of Vitamin D deficiency in the general population (up to 80 %). This is even higher in patients with chronic kidney disease (CKD) and increases with advancing stages of CKD. Objectives: To determine the difference in serum Vitamin D [25-hydroxyvitamin D, 25(OH) D] levels between CKD patients and normal healthy population. Materials and Methods: A prospective cross-sectional study involving 50 normal volunteers (control) and 50 patients with CKD stages 2-4. Their demographic profiles were recorded and blood samples taken for serum 25(OH) D, intact parathyroid hormone (iPTH) and other routine blood tests. Results: All subjects regardless of renal status had hypovitaminosis D (< 30ng/mL). The mean serum 25(OH) D were comparable in the control and CKD groups (15.3 ± 4.2 ng/mL vs 16.1 ± 6.2 ng/mL, p = NS). However, within the Vitamin D deficient group, the CKD group had lower levels of serum 25(OH) D [12.6(3.7) ng/mL vs 11.2(6.5) ng/mL, p = 0.039]. Female gender [OR 22.553; CI 95 % (2.16-235.48); p = 0.009] and diabetic status [OR 6.456; CI 95 % (1.144-36.433); p = 0.035] were independent predictors for 25(OH) D deficiency. Conclusions: Vitamin D insufficiency and vitamin D deficiency are indeed prevalent and under-recognized. Although the vitamin D levels among the study subjects and their control are equally low, the CKD group had severe degree of vitamin D deficiency. Diabetic status and female gender were independent predictors of low serum 25(OH)D. PMID:26933400

OBJECTIVES The diagnosis of chronic pancreatitis in patients with characteristic symptoms but normal pancreatic imaging is challenging. Assessment of pancreatic function through secretin pancreatic function testing (SPFT) has been advocated in this setting, but its diagnostic accuracy is not fully known. METHODS This was a retrospective review of patients who received SPFT at our tertiary care institution between January 1995 and December 2008 for suspected chronic pancreatitis. For all patients, medical records were reviewed for evidence of subsequent development of chronic pancreatitis by imaging and/or pathology. Patients were then categorized as “true positive” or “true negative” for chronic pancreatitis based on follow-up imaging or histologic evidence. RESULTS In all, 116 patients underwent SPFT. Of the 27 patients who tested positive, 7 were lost to follow-up. Of the remaining 20 SPFT-positive patients, 9 (45 %) developed radiologic or histologic evidence of chronic pancreatitis after a median of 4 years (1–11 years). Of the 89 patients who had negative SPFT testing, 19 were lost to follow-up. Of the remaining 70 patients, 2 were eventually diagnosed with chronic pancreatitis based on subsequent imaging/histology after a median follow-up period of 7 years (3–11 years). The sensitivity of the SPFT in diagnosing chronic pancreatitis was 82 % with a specificity of 86 %. The positive predictive value (PPV) of chronic pancreatitis was 45 % with a negative predictive value (NPV) of 97 %. CONCLUSIONS In patients with suspected early chronic pancreatitis and normal pancreatic imaging, SPFT is highly accurate at ruling out early chronic pancreatitis with a NPV of 97 %. PMID:23711627

BACKGROUND. There is frequent uncertainty in the identification of specific etiologies of chronic kidney disease (CKD) in children. Recent studies indicate that chromosomal microarrays can identify rare genomic imbalances that can clarify the etiology of neurodevelopmental and cardiac disorders in children; however, the contribution of unsuspected genomic imbalance to the incidence of pediatric CKD is unknown. METHODS. We performed chromosomal microarrays to detect genomic imbalances in children enrolled in the Chronic Kidney Disease in Children (CKiD) prospective cohort study, a longitudinal prospective multiethnic observational study of North American children with mild to moderate CKD. Patients with clinically detectable syndromic disease were excluded from evaluation. We compared 419 unrelated children enrolled in CKiD to multiethnic cohorts of 21,575 children and adults that had undergone microarray genotyping for studies unrelated to CKD. RESULTS. We identified diagnostic copy number disorders in 31 children with CKD (7.4% of the cohort). We detected 10 known pathogenic genomic disorders, including the 17q12 deletion HNF1 homeobox B (HNF1B) and triple X syndromes in 19 of 419 unrelated CKiD cases as compared with 98 of 21,575 control individuals (OR 10.8, P = 6.1 × 10–20). In an additional 12 CKiD cases, we identified 12 likely pathogenic genomic imbalances that would be considered reportable in a clinical setting. These genomic imbalances were evenly distributed among patients diagnosed with congenital and noncongenital forms of CKD. In the vast majority of these cases, the genomic lesion was unsuspected based on the clinical assessment and either reclassified the disease or provided information that might have triggered additional clinical care, such as evaluation for metabolic or neuropsychiatric disease. CONCLUSION. A substantial proportion of children with CKD have an unsuspected genomic imbalance, suggesting genomic disorders as a risk factor for

The pharmacokinetics and pharmacodynamics of ziconotide were assessed over a 48-hour period following intrathecal (i.t.) administration (1, 5, 7.5, or 10 micrograms) to 22 patients with chronic, nonmalignant pain. Plasma and cerebrospinal fluid (CSF) samples were obtained over a 24-hour period. Analgesic efficacy was monitored using Visual Analog Scale of Pain Intensity (VASPI) and Category Pain Relief Scores (CPRS) measurements. Pharmacokinetic (PK) parameters were calculated by noncompartmental methods. Plasma ziconotide data were insufficient for PK calculations. In CSF, the median half-life of ziconotide was 4.5 hours. The median CSF clearance and volume of distribution were 0.26 mL/min and 99 mL, respectively. CSF pharmacokinetics of ziconotide were linear, based on cumulative exposure and peak CSF concentrations. A dose-related analgesia was observed. Pharmacokinetic-pharmacodynamic efficacy and safety analyses showed that higher CSF ziconotide concentrations were generally associated with analgesia and increased incidence of nervous system adverse events following a 1-hour i.t. infusion.

Chronic Granulomatous Disease (CGD), caused by genetic defects in components of the phagocyte NADPH oxidase pathway, leads to recurrent life-threatening bacterial and invasive fungal infections. While a number of unique pathogens have been associated with this disease, the causative organisms may be difficult to identify. Here, we present a 24 year old male with known X-linked CGD who concurrently developed a cervical abscess and an abscess in the subcutaneous tissues of the right hip, both of which were surgically drained. Cultures failed to identify any organisms. He was treated empirically with ertapenem but the hip abscess recurred at the original site and in contiguous dependent areas in the posterior thigh and knee. A filamentous organism was observed microscopically, initially considered a contaminant, but on culture yielded a mold growth, identified as Phellinus tropicalis (synonym: Inonotus tropicalis) based on phenotypic and molecular methods. This is the third case report of human infection with P. tropicalis, all in subjects with CGD. The patient was treated with voriconazole with resolution of his symptoms. PMID:24310980

Recent brain functional magnetic resonance imaging (fMRI) studies have shown that chronic back pain (CBP) alters brain dynamics beyond the feeling of pain. In particular, the response of the brain default mode network (DMN) during an attention task was found abnormal. In the present work similar alterations are demonstrated for spontaneous resting patterns of fMRI brain activity over a population of CBP patients (n=12, 29–67 years old, mean=51.2). Results show abnormal correlations of three out of four highly connected sites of the DMN with bilateral insular cortex and regions in the middle frontal gyrus (p<0.05), in comparison with a control group of healthy subjects (n=20, 21–60 years old, mean=38.4). The alterations were confirmed by the calculation of triggered averages, which demonstrated increased coactivation of the DMN and the former regions. These findings demonstrate that CBP disrupts normal activity in the DMN even during the brain resting state, highlighting the impact of enduring pain over brain structure and function. PMID:20800649

Between 1988 and 1992, 21 biopsies for pathological examination were taken from 20 Senegalese leprosy patients suffering from chronic plantar ulcers (CPU) suspected of malignant transformation. The diagnosis of squamous cell carcinoma was effectively made in 13 cases and that of pseudoepitheliomatous hyperplasia in the remaining 8 cases. The mean period of time between the onset of CPU and that of malignant transformation was 10 years (range: 1 to 15 years); the mean annual frequency of the malignant transformation was 2 per 1,000 CPU. In countries where pathological examination is not available, below knee amputation could be considered whenever main clinical signs of malignant transformation are present. In countries where pathological examination is available, the therapeutic decision may differ according to the diagnosis: below knee amputation supplemented with block dissection of inguinal lymph nodes whenever possible in cases of carcinoma; below knee amputation depending on the function status of the foot and on the volume of tumor in case of pseudo-epitheliomatous hyperplasia.

The purpose of the current cross-sectional study was to test the associations between individual coping responses to pain, dyadic coping, and perceived social support, with a number of pain outcomes, including pain intensity, functional disability, and pain adjustment, in a sample of N = 43 patients suffering from chronic pain in Switzerland. In contrast to previous research, we were interested not only in specific pain coping but also in more general stress coping strategies and their potential influence on pain outcomes. Analyses were performed using correlation and regression analyses. “Praying and hoping” turned out to be an independent predictor of higher pain intensity and higher anxiety levels, whereas both “coping self-instructions” and “diverting attention” were associated with higher well-being, less feelings of helplessness, and less depression and anxiety. We further found a link between “focusing on and venting emotions” and “worse pain adjustment”. No significant relationship between dyadic coping and social support with any of our pain outcomes could be observed. Overall, our results indicate that individual coping strategies outweigh the effects of social support and dyadic coping on pain-related outcomes and pain adjustment. However, results need to be interpreted with caution given the small sample size. PMID:28331356

Low back pain (LBP) is a common disorder with a lifetime prevalence of 85%. The pathophysiology of LBP can be various depending on the underlying problem. Only in about 10% of the patients specific underlying disease processes can be identified. Patients with scoliosis, spondylolisthesis, herniated discs, adjacent disc disease, disc degeneration, failed back surgery syndrome or pseudoartrosis all have symptoms of LBP in different ways. Chronic low back pain patients are advised to stay active, however, there is no strong evidence that exercise therapy is significantly different than other nonsurgical therapies. Not every patient with symptoms of LBP is an appropriate candidate for surgery. Even with thorough systematic reviews, no proof can be found for the benefit of surgery in patients with low back pain, without serious neurologic deficit. And subjects like psychologic and socio-demographic factors also seem to be influencing a patients perception of back pain, expectations of treatment, and outcomes of treatment. Open lumbar fusion procedures are typically lengthy procedures and require a long exposure, which may result in ischemic necrosis of the paraspinal musculature, atrophy, and prolonged back pain. Minimally invasive spine surgery needed to take care of a decrease in muscle injuries due to retraction and avoidance of disruption of the osseotendineous complex of the paraspinal muscles, especially the multifidus attachment to the spinous process and superior articular process. Therefore, effort has been made to develop percutaneous fusion, as well as fixation methods, which avoid the negative effects of open surgery. Several minimally invasive fusion strategies have been described, like anterior lumbar interbody fusion (ALIF), posterior lumbar interbody fusion (PLIF), transforaminal lumbar interbody fusion (TLIF) and two lateral approaches (XLIF and DLIF), all with pro's and con's compared to open surgery and each other. The effect of MIS of all type is

Inflammatory joint disorders (IJD), including rheumatoid arthritis (RA), ankylosing spondylitis (ASp) and psoriatic arthritis (PsA), are prevalent conditions worldwide with a considerable burden on healthcare systems. IJD are associated with increased cardiovascular (CV) disease-related morbidity and mortality. In this review, we present an overview of the literature. Standardised mortality ratios are increased in IJD compared with the general population, that is, RA 1.3-2.3, ASp 1.6-1.9 and PsA 0.8-1.6. This premature mortality is mainly caused by atherosclerotic events. In RA, this CV risk is comparable to that in type 2 diabetes. Traditional CV risk factors are more often present and partially a consequence of changes in physical function related to the underlying IJD. Also, chronic systemic inflammation itself is an independent CV risk factor. Optimal control of disease activity with conventional synthetic, targeted synthetic and biological disease-modifying antirheumatic drugs decreases this excess risk. High-grade inflammation as well as anti-inflammatory treatment alter traditional CV risk factors, such as lipids. In view of the above-mentioned CV burden in patients with IJD, CV risk management is necessary. Presently, this CV risk management is still lacking in usual care. Patients, general practitioners, cardiologists, internists and rheumatologists need to be aware of the substantially increased CV risk in IJD and should make a combined effort to timely initiate CV risk management in accordance with prevailing guidelines together with optimal control of rheumatic disease activity. CV screening and treatment strategies need to be implemented in usual care.

Five patients with aphakia, glaucoma, and chronic inflammation were treated with ab interno sclerostomy by using the continuous wave Nd:YAG laser focused through a sapphire probe. After a follow-up period of 24 to 28 months, three of five patients had good intraocular pressure control. The sclerostomy failed in one patient when it was occluded by vitreous. The second failure was attributed to closure of the sclerostomy because of chronic intraocular inflammation.

A serologic study of Chagas disease was performed in 110 patients submitted to chronic hemodialisis and blood transfusions. Immunofluorescence antibody testing (IgG and IgM) was positive in 6 out of 62 patients receiving multiple blood transfusions (9.7%), but negative in all 48 subjects without transfusions. Thus, repeated blood transfusion is a significant risk for T cruzi infection in chronic hemodialized patients.

Juvenile fibromyalgia in children with sickle cell disease has not been reported in the literature. We report an adolescent patient with sickle cell whose pain symptoms progressed from having recurrent acute sickle cell pain crisis episodes to a chronic pain syndrome over several years. He was eventually diagnosed with juvenile fibromyalgia based on the clinical history and myofascial tender points and his pain symptoms responded better to multidisciplinary strategies for chronic fibromyalgia pain. Chronic pain in sickle cell disease is an area of poor research, and in addition there is inconsistency in the definition of chronic pain in sickle cell disease. Central sensitisation to pain is shown to occur after recurrent painful stimuli in a genetically vulnerable individual. In a chronic pain condition such as fibromyalgia central sensitisation is thought to play a key role. Fibromyalgia should be considered as one of the main differential diagnosis in any sickle cell patient with chronic pain.

The stimulus and response generalization effects of training wh-interrogative production were examined in 4 agrammatic Broca's aphasic subjects using a multiple baseline design across behaviors and subjects. Throughout treatment, response generalization to untrained questions and stimulus generalization to several nontraining conditions were assessed. Variable response generalization to untrained exemplars of trained wh-interrogative forms and little generalization to grammatically different wh constructions occurred. Stimulus generalization to only one of three conditions was noted. However, generalization treatment involving sequential modification of training across conditions was found to be effective in facilitating generalization to an additional stimulus condition for 2 of the 4 subjects.

A common perception is that the use of Internet-based self-care systems is best suited for a younger, tech-proficient population, and that these systems will increase the burden on patients with complex chronic conditions. The study stratified patients with diabetes into three regimens of use of an Internet-based diabetes self-care portal. Results show that patients were more likely to adhere to a diurnal regimen than a variable regimen, and older patients, over the age of 60, were more adherent than younger patients, regardless of regimen. This suggests that common misconceptions should be reconsidered when prescribing Internet-based interventions for patients with chronic illness.

Background Chronic inflammation is frequently observed on histological analysis of malignant and non-malignant prostate specimens. It is a suspected supporting factor for prostate diseases and their progression and a main cause of false positive PSA tests in cancer screening. We hypothesized that inflammation induces autoantibodies, which may be useful biomarkers. We aimed to identify and validate prostate inflammation associated serum autoantibodies in prostate cancer patients and evaluate the expression of corresponding autoantigens. Methods Radical prostatectomy specimens of prostate cancer patients (N = 70) were classified into high and low inflammation groups according to the amount of tissue infiltrating lymphocytes. The corresponding pre-surgery blood serum samples were scrutinized for autoantibodies using a low-density protein array. Selected autoantigens were identified in prostate tissue and their expression pattern analyzed by immunohistochemistry and qPCR. The identified autoantibody profile was cross-checked in an independent sample set (N = 63) using the Luminex-bead protein array technology. Results Protein array screening identified 165 autoantibodies differentially abundant in the serum of high compared to low inflammation patients. The expression pattern of three corresponding antigens were established in benign and cancer tissue by immunohistochemistry and qPCR: SPAST (Spastin), STX18 (Syntaxin 18) and SPOP (speckle-type POZ protein). Of these, SPAST was significantly increased in prostate tissue with high inflammation. All three autoantigens were differentially expressed in primary and/or castration resistant prostate tumors when analyzed in an inflammation-independent tissue microarray. Cross-validation of the inflammation autoantibody profile on an independent sample set using a Luminex-bead protein array, retrieved 51 of the significantly discriminating autoantibodies. Three autoantibodies were significantly upregulated in both screens, MUT

In 6 volunteers with normal renal function, we investigated the effects of various kinds of protein (soy, lactoprotein and beef) and various amounts of an intravenously administered amino acid solution on glomerular filtration (GFR) and effective renal plasma flow (ERPF). As for the protein-induced changes in renal function, rises in GFR and ERPF were lowest with soy protein, and highest with beef (baseline GFR, 110 +/- 5; soy, 122 +/- 5; beef, 131 +/- 5 ml/min/1.73 m2; mean +/- SEM). High doses of intravenous amino acids induced a rise in GFR comparable to that after beef (132 +/- 5 ml/min/1.73 m2). In a combined test a liquid mixed meal together with intravenously administered amino acids induced a comparable increase of the GFR (baseline 114 +/- 5 versus 129 +/- 5 ml/min/1.73 m2). When investigating 9 patients with chronic renal insufficiency after 4 weeks of low protein intake (LP) and after 4 weeks of high protein intake (HP), GFR and ERPF rose significantly under baseline conditions (GFR-LP41 +/- 9 versus GFR-HP 45 +/- 9 ml/min/1.73 m2, p less than 0.02; ERPF-LP 169 +/- 39 versus ERPF-HP 180 +/- 40 ml/min/1.73 m2, p less than 0.02; paired Wilcoxon). At the end of both dietary periods a comparable rise in renal function could be induced through acute stimulation (GFR-LP 20 +/- 5, GFR-HP 16 +/- 4; ERPF-LP 23 +/- 7, ERPF-HP 22 +/- 3%).(ABSTRACT TRUNCATED AT 250 WORDS)

The present study aimed to investigate possible differences in family environment among patients experiencing their First Episode of Psychosis (FEP), chronic patients and controls. Family cohesion and flexibility (FACES-IV) and psychological distress (GHQ-28) were evaluated in families of 50 FEP and 50 chronic patients, as well as 50 controls, whereas expressed emotion (FQ) and family burden (FBS) were assessed in families of FEP and chronic patients. Multivariable linear regression analysis, adjusted for confounders, indicated impaired cohesion and flexibility for families of FEP patients compared to controls, and lower scores for families of chronic patients compared to those of FEP patients. Caregivers of chronic patients scored significantly higher in criticism, and reported higher burden and psychological distress than those of FEP patients. Our findings suggest that unbalanced levels of cohesion and flexibility, high criticism and burden appeared to be the outcome of psychosis and not risk factors triggering the onset of the illness. Furthermore, emotional over-involvement both in terms of positive (i.e. concern) and negative behaviors (i.e. overprotection) is prevalent in Greek families. Psychoeducational interventions from the early stages of the illness should be considered to promote caregivers' awareness regarding the patients' illness, which in turn, may ameliorate dysfunctional family interactions.

Norovirus infection causes a significant burden of morbidity and (in the developing world) mortality. In immunocompromised hosts, norovirus infection can become chronic, with devastating consequences. Unfortunately, therapeutic options for chronic disease are unproven, and treatment is largely supportive. We report a case of norovirus infection causing debilitating chronic gastroenteritis in a transplant patient that responded to a short course of enterally administered human immune globulin.

Chronic migraine, a subtype of migraine defined as ≥ 15 headache days per month for ≥ 3 months, in which ≥ 8 days per month meet criteria for migraine with or without aura or respond to migraine-specific treatment, is a disabling, underdiagnosed, and undertreated disorder associated with significant disability, poor health-related quality of life, and high economic burden. The keys to caring for chronic migraine patients include: (1) making a proper diagnosis; (2) identifying and eliminating exacerbating factors; (3) assessing for medication overuse (patients with chronic headache often overuse acute medications); and (4) continued management. Communication between patient and physician about treatment goals is important. The patient management guidelines presented in this article should help physicians improve treatment success and proactively address common comorbidities among their patients with chronic migraine.

Migraine is a common neurological disorder, characterised by severe headaches. Epidemiological studies in the USA and Europe have identified a subgroup of migraine patients with chronic migraine. Chronic migraine is defined as ≥15 headache days per month for ≥3 months, in which ≥8 days of the month meet criteria for migraine with or without aura, or respond to treatment specifically for migraine. Chronic migraine is associated with a higher burden of disease, more severe psychiatric comorbidity, greater use of healthcare resources, and higher overall costs than episodic migraine (<15 headache days per month). There is a strong need to improve diagnosis and therapeutic treatment of chronic migraine. Primary care physicians, as well as hospital-based physicians, are integral to the identification and treatment of these patients. The latest epidemiological data, as well as treatment options for chronic migraine patients, are reviewed here.

Chronic Disease is defined as a long lasting health condition, which can develop and/or worsen over an extended time, but which can also be controlled. The monetary and budgetary toll due to its persistent nature has become unsustainable and requires pressing actions to limit their incidence and burden. This paper demonstrates the utility of the System Dynamics approach to simulate the behavior of key factors involved in the implementation of chronic disease management. We model the patient flow diversion from emergency departments (ED) to patient-centered medical homes (PCMH), with emphasis on the visit rates, as well as the effect of insurance coverage, in an effort to assure continuity of quality care for Asthma patients at lower costs. The model is used as an evaluative method to identify conditions of a maintained health status through adequate policy planning, in terms of resources and capacity. This approach gives decision makers the ability to track the level of implementation of the intervention and generate knowledge about dynamics between population demands and the intervention effectiveness. The functionality of the model is demonstrated through the consideration of hypothetical scenarios executed using sensitivity analysis. PMID:26770663

The introduction and the extended clinical use of nilotinib in the first-line treatment of chronic myeloid leukemia have been based on company-sponsored trials. Independent confirmations are extremely important. We report an investigator-sponsored study of nilotinib 300 mg twice daily in 130 chronic myeloid leukemia patients in early chronic phase. A deep molecular response was achieved in 46% (MR(4.0)) and 17% (MR(4.5)) of patients at 2 years; 58% of the enrolled patients achieved a MR(4.0) at least once, with a sustained MR(4.0) in 52% of them. With a median observation of 29 months (range 24-37 months), 77% of patients were still on treatment with nilotinib. The reasons for permanent discontinuation were: 3% progression, 5% failure or suboptimal response, 8% adverse events, 1% treatment-free remission, and 5% other reasons. Thirteen thrombotic arterial events were reported in 12 patients. A prospective evaluation of metabolic effects showed an increase of fasting glucose without significant variations of glycated hemoglobin, an increase of total cholesterol (both low density lipoprotein and high density lipoprotein fractions) and a decrease of triglycerides. This study confirms a high and rapid efficacy of nilotinib 300 mg twice daily and provides detailed information on the type and incidence of non-hematologic and metabolic adverse events (clinicaltrials.gov identifier: 01535391).

A novel in vivo model for the study of antibiotic-induced release of endotoxin from gram-negative bacteria is described. The model uses the chronically colonized urinary tracts of patients whose spinal cords have been injured. At baseline, the organisms were present in the range of 1 x 10(3) to 2 x 10(7) CFU/ml, and the concentration of endotoxin ranged from 2 x 10(-1) to 1 x 10(3) ng/ml in 44 studies. In 10 control studies, the concentration of endotoxin and the numbers of viable gram-negative bacteria over time changed by an average of less than 0.15 log10 units from the baseline values. At 2 h after antibiotic administration, the average decrease in CFU was 0.93 log10 units, and because antibiotics cause the release of endotoxin, an average increase in endotoxin concentration of 0.59 log10 units was noted in 21 studies with susceptible bacteria. Similar changes in response to antibiotic exposure were seen in studies with susceptible Pseudomonas bacteria in comparison with those seen in studies with susceptible members of the family Enterobacteriaceae. These results provide evidence that this novel model may be useful for comparing the effects of antibiotics with different modes of action, both as single agents and in combination, on the concentration of endotoxin in relation to changes in the numbers of bacteria, under conditions of bacterial replication and antibiotic exposure more closely resembling those found in vivo than is possible in other models.

Purpose We investigated the association between cognitive impairment and chronic obstructive pulmonary disease (COPD), taking into account demographic and clinical variables evaluated during routine practice. Patients and methods We performed a post hoc analysis of a cross-sectional study that included subjects with stable COPD. Sociodemographic and clinical information was recorded using the Body mass index, airflow Obstruction, Dyspnea and Exacerbations index and the Charlson comorbidity index. Cognitive performance was studied by the mini-mental state examination, with a score less than 27 indicating clinical impairment. Depressive symptoms, physical activity, and quality of life (EuroQoL-5 dimensions and COPD Assessment Test) were also evaluated. Results The analysis included 940 subjects. The prevalence of cognitive impairment was 39.4%. Multivariate logistic regression models revealed that cognitive impairment was associated with educational level (odds ratio [OR] =0.096, 95% confidence interval [CI] =0.011–0.447) and poorer quality of life measured by the EuroQoL-5 dimensions social tariff (OR =0.967, 95% CI =0.950–0.983). When questionnaires were not included in the analysis, cognitive impairment was associated with educational level (OR =0.063, 95% CI =0.010–0.934), number of exacerbations (OR =11.070, 95% CI =1.450–84.534), Body mass index, airflow Obstruction, Dyspnea and Exacerbations index score (OR =1.261, 95% CI =1.049–1.515), and the Charlson comorbidity index (OR =1.412, 95% CI =1.118–1.783). Conclusion Cognitive impairment is common in COPD and is associated with low educational level, higher disease severity, and increased comorbidity. This could have therapeutic implications for this population. PMID:27042043

Abstract Chronic widespread pain (CWP) is common in the general population. It is unclear how people reporting this problem present in primary care; they may regularly consult for regional pains without being recognized as having a generalized condition. Our objectives were to determine the prevalence of people consulting in primary care for musculoskeletal conditions in different body regions on different occasions (recurrent regional pain consultation), the proportion with diagnosed generalized pain and survey-reported widespread pain, and if they have features characteristic of CWP. Phase 1 used electronic records from 12 general practices in North Staffordshire (Consultations in Primary Care Archive) from 2005 to 2009. Phase 2 used linked self-reported health and primary health care data from 8286 people aged >50 years in 8 general practices (North Staffordshire Osteoarthritis Project) between 2002 and 2005. In Phase 1, 11% of registered patients fulfilled criteria for recurrent regional pain consultation. Three-quarters had no recorded CWP-related generalized pain condition (eg, fibromyalgia). In Phase 2, 53% of recurrent regional pain consulters had survey-reported widespread pain and 88% had consulted for somatic symptoms. Self-reported general health was worse in recurrent regional pain consulters than in single-region consulters and poorest in those who also reported persistent widespread pain. Recurrent regional pain consulters are a heterogeneous group of frequent consulters sharing features with CWP (eg, somatic symptoms) but including those less severely affected. They lie on the spectrum of polysymptomatic distress characteristic of CWP and represent a group whose needs may be better met by earlier diagnosis of multisite pain. PMID:27749607

Objective: Studies related to sleep disorders and polysomnography (PSG) among chronic daily headache patients are rare. We studied this and compared chronic migraine (CM) with chronic tension-type headache. Methods: Eighty-three patients were recruited. They were evaluated by semi-structured interview, headache, and sleep diaries along with Epworth Sleepiness Scale score and insomnia symptom score. Overnight PSG was performed and data compared. Results: Chronic tension-type headache was more common than CM, both having female preponderance. Insomnia followed by excessive daytime sleepiness was prevalent sleep disorder. Sleep efficiency and Stage 3 sleep were lower in CM compared to chronic tension-type. ESSS was significantly increased among chronic tension-type patients. No significant correlation was found among PSG parameters in patients with or without sleep disorders. Conclusion: Insomnia being most common sleep disorder among chronic headache population. Chronic tension-type headache had slightly better slow-wave sleep than CM and significantly increased daytime sleepiness. PMID:28163508
Chronic demyelinating disorders have multifactorial origin but common important physiologic and anaesthetic considerations. Choice of anaesthesia technique and the drugs used, undertanding the pros and cons of using central neuraxial blocks will help in successful management of such patients. We describe the anaesthetic management of a 34-year-old male with chronic inflammatory demyelinating polyneuropathy posted for cystolithotripsy. PMID:27790558

To examine the protein anabolic actions of insulin in chronic renal failure, the authors measured four sets of whole body leucine fluxes during insulin alone and insulin with amino acid infusion in nine uremic patients before hemodialysis (B-HD). Seven were restudied 8 wk after initiation of maintenance hemodialysis (HD). Six normal subjects served as control (N). All values ( micro mol/kg/h, mean +/- SEM) are presented in the sequence of B-HD, HD, and N, and only P < 0.05 are listed. During Flux 1 (baseline), D (leucine release from body protein degradation) were 114 +/- 7, 126 +/- 4, and 116 +/- 6, respectively. C (leucine oxidation rates) were 18 +/- 2, 17 +/- 2, and 21 +/- 3, respectively. S (leucine disappearance into body protein [index of protein synthesis]) were 96 +/- 6, 107 +/- 4, and 94 +/- 4, respectively, and balances (net leucine flux into protein [values were negative during fasting]) were -18 +/- 2, -17 +/- 2, and -21 +/- 3, respectively. During Flux 2 (low-dose insulin infusion), D were 89 +/- 3, 98 +/- 6, and 94 +/- 5, respectively; C were 12 +/- 1, 11 +/- 2, and 18 +/- 1, respectively (P = 0.02); S were 77 +/- 4, 87 +/- 5, and 76 +/- 5, respectively, and balances were -12 +/- 1, -11 +/- 2, and -18 +/- 1, respectively (P = 0.02). During Flux 3 (high-dose insulin infusion): D were 77 +/- 3, 82 +/- 7, and 84 +/- 5, respectively; C were 9 +/- 1, 8 +/- 1, and 14 +/- 1, respectively (P = 0.005); S were 68 +/- 4, 74 +/- 6, and 70 +/- 5, respectively, and balances were -9 +/- 1, -8 +/- 1, and -14 +/- 1, respectively (P = 0.005). In Flux 4 (insulin infused with amino acids): D were 73 +/- 3, 107 +/- 18, and 85 +/- 7, respectively; C were 35 +/- 4, 29 +/- 5, and 39 +/- 3, respectively; S were 105 +/- 5, 145 +/- 15, and 113 +/- 6, respectively (P = 0.02), and balances were 32 +/- 4, 38 +/- 5, and 27 +/- 3, respectively. These data show that B-HD and HD patients were as sensitive as normal subjects to the protein anabolic actions of insulin. Insulin alone

Chronic hepatitis C virus (HCV) infection combined with occult hepatitis B virus (HBV) infection has been associated with increased risk of hepatitis, cirrhosis and hepatocellular carcinoma. This study aimed to determine the prevalence of occult HBV infection among Egyptian chronic HCV patients, the genotype and occurrence of surface gene mutations of HBV and the impact of co-infection on early response to treatment. The study enrolled 162 chronic HCV patients from Ismailia Fever Hospital, Egypt, who were HBV surface antigen-negative. All patients were given clinical assessment and biochemical, histological and virological examinations. HBV-DNA was detectable in sera from 3 patients out of the 40 patients who were positive for hepatitis B core antibody. These 3 patients were responsive to combination therapy at treatment week 12; only 1 of them had discontinued therapy by week 24. HBV genotype D was the only detectable genotype in those patients, with absence of "a" determinant mutations among those isolates.

Ureterocele is a congenital anomaly, in which there is mal-development of the caudal segments of the ureter. There is a female preponderance with most cases seen in Caucasians. Among the reported complications of this condition, chronic renal failure occurring in the setting of ureterocele has not been well documented. We report a case of a young girl with bilateral ureterocele presenting with chronic renal failure, whose management presented a diagnostic failure and inadequate treatment.

Chronic pain often interferes with daily functioning, and may become a threat to an individual's sense of self. Despite the development of a recent theoretical account focussing upon the relationship between the presence of chronic pain and a person's self, research investigating this idea is limited. In the present study we aimed to (1) compare the strength of association between self- and pain schema in patients with chronic pain and healthy control subjects and (2) research whether the strength of association between self- and pain-schema is related to particular pain-related outcomes and individual differences of patients with chronic pain. Seventy-three patients with chronic pain (M(age) = 49.95; SD = 9.76) and 53 healthy volunteers (M(age) = 48.53; SD = 10.37) performed an Implicit Association Test (IAT) to assess the strength of association between pain- and self-schema. Patients with chronic pain also filled out self-report measures of pain severity, pain suffering, disability, depression, anxiety, acceptance, and helplessness. Results indicated that the pain- and self-schema were more strongly associated in patients with chronic pain than in healthy control subjects. Second, results indicated that, in patients with chronic pain, a stronger association between self- and pain-schema, as measured with the IAT, is related to a heightened level of pain severity, pain suffering, anxiety, and helplessness. Current findings give first support for the use of an IAT to investigate the strength of association between self- and pain-schema in patients with chronic pain and suggest that pain therapies may incorporate techniques that intervene on the level of self-pain enmeshment.

Understanding of the relation between the alcoholic consumption and the development of pancreatitis should help in defining the alcoholic etiology of pancreatitis. Although the association between alcohol consumption and pancreatitis has been recognized for over 100 years, it remains still unclear why some alcoholics develop pancreatitis and some do not. Surprisingly little data are available about alcohol amounts, drinking patterns, type of alcohol consumed and other habits such as dietary habits or smoking in respect to pancreatitis preceding the attack of acute pancreatitis or the time of the diagnosis of chronic pancreatitis. This review summarizes the current knowledge. Epidemiological studies clearly show connection between the alcohol consumption in population and the development of acute and chronic pancreatitis. In the individual level the risk to develop either acute or chronic pancreatitis increases along with the alcohol consumption. Moreover, the risk for recurrent acute pancreatitis after the first acute pancreatitis episode seems also to be highly dependent on the level of alcohol consumption. Abstaining from alcohol may prohibit recurrent acute pancreatitis and reduce pain in chronic pancreatitis. Therefore, all the attempts to decrease alcohol consumption after acute pancreatitis and even after the diagnosis of chronic pancreatitis should be encouraged. Smoking seems to be a remarkable co-factor together with alcohol in the development of chronic pancreatitis, whereas no hard data are available for this association in acute pancreatitis. Setting the limits for accepting the alcohol as the etiology cannot currently be based on published data, but rather on the 'political' agreement.

Backgrounds—Hepatic fibrosis is one of the main consequences of liver disease. Both fibrosis and steatosis may be seen in some patients with chronic hepatitis C and alcoholic liver disease (ALD). Aims—To quantitate fibrosis and steatosis by stereological and morphometric techniques in patients with chronic hepatitis C and compare the results with a control group of patients with ALD. In addition, to correlate the quantitative features of fibrosis with the Ishak modified histological score. Materials and methods—Needle liver biopsies from 86 patients with chronic hepatitis C and from 32 patients with alcoholic liver disease (disease controls) were analysed by stereological and morphometric analyses using the Prodit 5.2 system. Haematoxylin and eosin and Picro-Mallory stained sections were used. The area fractions (AA) of fibrosis, steatosis, parenchyma, and other structures (bile duct and central vein areas) were assessed by stereological method. The mean diameters of fat globules were determined by morphometric analysis. Results—Significant differences were found in the AA of fibrosis, including fibrosis within portal tract areas, between chronic hepatitis C patients and those with ALD (mean (SD): 19.14 (10.59) v 15.97 (12.51)). Portal and periportal (zone 1) fibrosis was significantly higher (p = 0.00004) in patients with chronic hepatitis C compared with the control group (mean (SD): 9.04 (6.37) v 3.59 (3.16)). Pericentral fibrosis (zone 3) occurred in both groups but was significantly more pronounced in patients with ALD. These results correlate well with the modified Ishak scoring system. However, in patients with cirrhosis (stage 6) with chronic hepatitis C the AA of fibrosis varied between 20% and 74%. The diameter of fat globules was significantly lower in patients with hepatitis C (p = 0.00002) than the ALD group (mean (SD): 14.44 (3.45) v 18.4 (3.32)). Microglobules were more frequent in patients with chronic hepatitis C than in patients with ALD

Aim: Anemia of chronic disease is defined as anemia occurring in chronic infections and inflammatory conditions that is not caused by marrow deficiencies or other diseases and in the presence of adequate iron stores and vitamins. The present case control study was aimed to assess the red blood cell parameters for signs of anemia in patients with mild, moderate, and severe chronic periodontitis. Materials and Methods: A simple random sampling method was used to select 80 healthy male patients, who were divided into four groups based on full mouth periodontal examination as follows: group I patients comprised the control group (n = 20), which included patients with a clinically healthy periodontium, group II patients (n = 20) were diagnosed with mild chronic periodontitis, group III (n = 20) included moderate chronic periodontitis patients, and patients with severe chronic periodontitis formed group IV (n = 20). Laboratory blood investigations included total number of erythrocytes, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration. Results: Data analysis showed a statistically significant decrease in red blood cell parameters with increase in different grades of periodontitis. Conclusion: Results of the present study show a substantial decrease in red blood cell parameters with increase in the severity of periodontal destruction. PMID:26759801
Capital Health in Edmonton, Alberta, implemented a system-wide chronic disease management model to support people with chronic disease and their primary care physicians. Groups of family physicians, in partnership with the health region, developed primary care networks to provide services that are customized to meet the priorities of the local community. Management of chronic disease is a cornerstone service, and diabetes management is the most fully developed program. Key to its success are standardized protocols, consistent follow-up and patient education by trained primary care nurses. This model will be used as a template for the management of other chronic diseases.

This paper examines the effect of semantic variables on serial recall in two contrasting aphasic cases and a group of controls. Experiment 1 manipulates word imageability and Experiment 2 manipulates semantic similarity. Controls not only showed better recall of imageable/semantically grouped lists, but under some conditions they also produced proportionately fewer phonological errors. These findings suggest that increasing the effectiveness of lexical/semantic support reduces reliance on phonological support. Consistent with this proposal, case TV, whose phonological impairment should increase his reliance on lexical/semantic support, produced abnormally low rates of phonological errors under some conditions. Conversely, case NP, who had a lexical/semantic impairment, produced abnormally high rates of phonological errors under some conditions. Analysis of serial recall curves in both aphasics and controls support the hypothesis that phonological processes are particularly critical for the recall of list-final items. However, there was no evidence that semantic support is especially crucial for list-initial recall. Controls did not exhibit stronger effects of semantic variables at list-initial position. Case NP (lexical/semantic impairment) performed disproportionately poorly on these items, but only under certain conditions.

Granulocytic sarcoma, also known as myeloid sarcoma, is an extramedullary tumour composed of immature myeloid cells. Granulocytic sarcoma is typically found in patients with acute myeloid leukaemia, accelerated phase or blast crisis of chronic myeloid leukaemia, myelodysplastic syndrome, or as an isolated event without bone marrow involvement. We present a case of granulocytic sarcoma in a patient with chronic myeloid leukaemia in the setting of complete haematological, molecular and cytogenetic remission. Our patient was first treated with imatinib for chronic-phase chronic myeloid leukaemia. After maintaining remission for 42 months, he developed a granulocytic sarcoma in his spine. In this case report, we describe our case, along with the three other cases reported in the literature. In addition to being a rare diagnosis, this case demonstrates the importance of being vigilant in diagnosing the cause of back pain and atypical symptoms in patients with a history of leukaemia.

The article shows the results of treatment of 118 patients with chronic hepatitis C (CHC) which is associated with type 2 diabetes mellitus (DM). When planning therapeutic interventions in chronic hepatitis C in patients with diabetes, it is considered the presence of visceral obesit , dyslipidemia, and hepatic steatosis. The efficacy of different treatment regimens was studied. Found that the usage of ursodeoxycholic acid and ademetionin in HCV patients with diabetes type 2 receiving standard antiviral therapy (SAVT), significantly make a positive effect on the level of dyslipidemia. The normalization of lipid profile allows for a full course of SAVT, which reduces the frequency of relapse. It is also noted that the simultaneous use of ademetionin and ursodeoxycholic acid in treatment of chronic hepatitis C leads to a reduction of side effects of SAVT. Metabolic therapy may be recommended for patients with chronic hepatitis C in combination with type 2 diabetes in case of SAVT, and at its contraindications or intolerance.

The co-existence of both chronic myeloid leukemia (CML) and chronic lymphocytic leukemia (CLL) have been described in a few cases, either simultaneously or subsequently presenting. We report an unusual case of three he-matological malignancies in the same patient: CLL, CML, and acute myeloid leukemia (AML). None of the three malignancies shared the same origin, since the marrow sample was negative for BCR-ABL1 transcript at the time of CLL diagnosis, CLL was in remission at CML diagnosis, and CML was in complete cytogenetic response at AML onset, indicating that this was not a blast crisis. Background: Chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML) are the most common proliferative disorders in Western countries, with an incidence of 4.2/100,000/year and 1-1.5/100,000/year, respectively. The co-existence of both CML and CLL is an extremely rare event, even if it has been described in a few cases, either simultaneously or subsequently presenting. Above all, the presence of more than two different hematologic neoplasms has not been described in literature so far. In the present study we report a particular case of a CLL patient, who first developed CML and then acute myeloid leukemia (AML).

Using heuristically-guided state space search, a prototype program has been developed to simulate and classify phonemic errors occurring in the speech of neurologically-impaired patients. Simulations are based on an interchangeable rule/operator set of elementary errors which represent a theory of phonemic processing faults. This work introduces and evaluates a novel approach to error simulation and classification, it provides a prototype simulation tool for neurolinguistic research, and it forms the initial phase of a larger research effort involving computer modelling of neurolinguistic processes.

Randomized trials can provide important direction to clinical decision-making; however, their strength of inferences may be weakened by methodological limitations, the extent that their reported outcomes fail to address patient-important end points and by failing to report results that provide interpretable estimates of magnitude of effect. Strategies that investigators can use to address interpretability include reporting mean differences between groups in relation to the minimal important difference and reporting the proportion of patients who benefit from treatment and the associated number needed to treat. These strategies also apply to reporting pooled estimates from meta-analyses, even when studies use different instruments to measure the same construct. We illustrate these techniques using, as an example, current evidence for the use of opioids in chronic noncancer pain.

The article examines two concepts of counselling of patients by nurses that are popular in the German-speaking area with regard to their underlying scientific standpoint and ideals and their implications on counselling-process and -result. The authors determine that both concepts disregard the biographic construction processes which are so important for coping with and tackling chronic illness. The article concludes with a discussion of prospective use of biographic diagnostics in counselling of patients with chronic illness.

We report a patient with broad anterior synechias and corneal endothelial damage. The patient had chronic iritis and cataracts secondary to chronic iritis in both eyes. Because the right eye had broad anterior synechias and severe corneal endothelial damage, extracapsular cataract extraction and intraocular lens implantation were performed through the basal iris. Good postoperative visual acuity was obtained. The cornea showed little trauma from the surgery and remained clear 36 months postoperatively.

Chronic low back pain (chronic LBP) is both debilitating for patients but also a major burden on the health care system. Previous studies reported various maladaptive structural and functional changes among chronic LBP patients on spine- and supraspinal levels including behavioral alterations. However, evidence for cortical reorganization in the sensorimotor system of chronic LBP patients is scarce. Motor Imagery (MI) is suitable for investigating the cortical sensorimotor network as it serves as a proxy for motor execution. Our aim was to investigate differential MI-driven cortical processing in chronic LBP compared to healthy controls (HC) by means of functional magnetic resonance imaging (fMRI). Twenty-nine subjects (15 chronic LBP patients, 14 HC) were included in the current study. MI stimuli consisted of randomly presented video clips showing every-day activities involving different whole-body movements as well as walking on even ground and walking downstairs and upstairs. Guided by the video clips, subjects had to perform MI of these activities, subsequently rating the vividness of their MI performance. Brain activity analysis revealed that chronic LBP patients exhibited significantly reduced activity compared to HC subjects in MI-related brain regions, namely the left supplementary motor area and right superior temporal sulcus. Furthermore, psycho-physiological-interaction analysis yielded significantly enhanced functional connectivity (FC) between various MI-associated brain regions in chronic LBP patients indicating diffuse and non-specific changes in FC. Current results demonstrate initial findings about differences in MI-driven cortical processing in chronic LBP pointing towards reorganization processes in the sensorimotor network. PMID:26569602

There is ample evidence that Staphylococcus aureus capsular polysaccharide (CP) promotes virulence. Loss of capsule expression, however, may lead to S. aureus persistence in a chronically infected host. This study was conducted to determine the relative prevalence of nonencapsulated S. aureus in patients with chronic and acute osteomyelitis. Only 76/118 (64%) S. aureus isolates from patients with osteomyelitis expressed CP, whereas all 50 isolates from blood cultures of patients with infections other than osteoarticular infections expressed CP (P = 0.0001). A significantly higher prevalence of nonencapsulated S. aureus was found in patients with chronic osteomyelitis (53%) than in those with acute osteomyelitis (21%) (P = 0.0046). S. aureus isolates obtained from multiple specimens from five of six patients with chronic osteomyelitis exhibited phenotypic (expression of CP, α-hemolysin, β-hemolysin, slime, and the small-colony variant phenotype) and/or genotypic (pulsed-field gel electrophoresis and spa typing) differences. Nonencapsulated S. aureus was recovered from at least one specimen from each chronic osteomyelitis patient. Fourteen isolates obtained from two patients with acute osteomyelitis were indistinguishable from each other within each group, and all produced CP5. In conclusion, we demonstrated that nonencapsulated S. aureus is more frequently isolated from patients with chronic osteomyelitis than from those with acute osteomyelitis, suggesting that loss of CP expression may be advantageous to S. aureus during chronic infection. Our findings on multiple S. aureus isolates from individual patients allow us to suggest that selection of nonencapsulated S. aureus is likely to have occurred in the patient during long-term bone infection.

We investigated the influence of phonological neighborhood density (PND) on the performance of aphasic speakers whose naming impairments differentially implicate phonological or semantic stages of lexical access. A word comes from a dense phonological neighborhood if many words sound like it. Limited evidence suggests that higher density facilitates naming in aphasic speakers, as it does in healthy speakers. Using well controlled stimuli, Experiment 1 confirmed the influence of PND on accuracy and phonological error rates in two aphasic speakers with phonological processing deficits. In Experiments 2 and 3, we extended the investigation to an aphasic speaker who is prone to semantic errors, indicating a semantic deficit and/or a deficit in the mapping from semantics to words. This individual had higher accuracy, and fewer semantic errors, in naming targets from high versus low density neighborhoods. It is argued that the results provide strong support for interactive approaches to lexical access, where reverberatory feedback between word- and phoneme-level lexical representations not only facilitates phonological level processes but also privileges the selection of a target word over its semantic competitors.

We examined 143 patients, aged 18-65 years, with chronic low back pain, in 78 of patients diagnosed as chronic somatoform pain disorder (CSPD)--ICD-10 F45.4--and in 65 as chronic pain syndrome (CPS) caused by spine pathology (M48.0, M51.1, M54.4). Depressive symptoms predominated in CSPD patients, who exhibited more pronounced psychopathological disturbances and two-fold higher frequency of personality disorders, comparing to those with CPS. In CSPD patients pain severity and reaction to pain syndrome were significantly higher than in CPS patients. Psychodiagnostic study revealed higher expressed anxiety and depression as well as socio-psychological maladaptation in CSPD patients as compared to CPS ones. After neurological examination, significant between-group differences were found in the frequency of muscular-tonic myofacial, syndrome and iliosacral joint dysfunction.

Chronic lymphocytic leukemia, the most common adult leukemia worldwide, is considered an indolent but incurable non-Hodgkin lymphoma. Leukemia cutis is an uncommon manifestation of chronic lymphocytic leukemia. We present a case of an adult patient who presented with skin lesion of bilateral ears, which led to the diagnosis of chronic lymphocytic leukemia. We also reviewed the cases of auricular involvement in chronic lymphocytic leukemia patients reported in the literature. Local treatment is indicated in case of leukemia cutis; however, systemic treatment is recommended when there are systemic signs and symptoms. Better awareness of disease evolution and prompt diagnosis of this leukemia cutis of chronic lymphocytic leukemia will improve the effectiveness and outcome of its management. PMID:28228955

Chronic pain is common in individuals with HIV infection. The primary goal of treatment of chronic pain is not only to improve pain but also to improve physical and emotional function. Patients with chronic pain should be assessed for concurrent psychiatric and substance use disorders, as these conditions often coexist. Treatment of chronic pain may have limited success in the absence of treatment of psychiatric disorders. Treatments for chronic pain include nonopioid pharmacologic therapies and nonpharmacologic therapies (eg, cognitive and behavioral therapy, physical therapy), and the latter option is often the most effective for improving patient function. Care must be taken when initiating or continuing treatment with opioids, and the risks and benefits of treatment with opioids should be regularly assessed. This article summarizes a presentation by Jessica S. Merlin, MD, MBA, at the IAS-USA continuing education program held in New York, New York, in March 2015.

Studies investigating the prevalence of multiple chronic conditions (MCCs) and their associated health care cost and use among pediatric populations have been limited. Among 14,404 pediatric patients receiving outpatient care in southeastern Michigan from 2008 through 2013, 82.1% had 0 chronic conditions, 16.2% had 1 chronic condition, and 1.6% had 2 or more chronic conditions. Greater numbers of chronic conditions significantly predicted outpatient cost (β = 581.7, P < .001), visit frequency (β = 9.1, P < .001), and days between appointments (β = -33.9, P < .001). Further study of MCCs among pediatric patients is needed given their increasing prevalence and their associated health care cost and use.

Abstract Prevalence of chronic hepatitis C (CH-C) infection in patients of Asian ancestry ranges between 1% and 20%. Interferon (IFN)- and ribavirin (RBV)-containing regimens for CH-C have a negative impact on patient-reported outcomes (PROs) during treatment. The aim of this study was to assess the impact of IFN-free RBV-free sofosbuvir (SOF)-based regimens on PROs in CH-C patients of Asian ancestry. In this observational retrospective study, the PRO data from 12 multicenter multinational phase 3 clinical trials (2012–2015, conducted in Europe, North America, Australia, and New Zealand) of SOF-based regimens with and without IFN, ledipasvir (LDV), and/or RBV were used. At baseline, during treatment, and post-treatment, patients completed 4 validated PRO questionnaires (SF-36, CLDQ-HCV, FACIT-F, and WPAI:SHP). The resulting PROs in Asian patients were compared across the treatment regimens. Of 4485 of the trials’ participants, 106 patients were of Asian ancestry (55.7% male, 69.8% treatment-naïve, 17.0% cirrhotic). In comparison with other patients, the Asian CH-C cohort was younger, had lower BMI, and lower rates of pre-treatment psychiatric comorbidities (anxiety, depression, sleep disorders) (all P < .05). At baseline, Asian patients also had lower SF-36 physical functioning scores (on average, by −5.6% on a normalized 0–100% PRO scale, P = .001). During treatment, Asian CH-C patients experienced a decline in their PRO scores while receiving IFN and/or RBV-containing regimens (up to −19.6%, P < .001). In contrast, patients receiving LDV/SOF experienced no PRO decrement and improvement of some PRO scores during treatment (+9.0% in general health of SF-36, P = .03). After achieving SVR-12, some of the PRO scores in Asian patients improved regardless of the regimen (up to +9.3%, P < .001). In multivariate analysis of Asian patients, the use of LDV/SOF was independently associated with higher PRO scores during and soon after the end of

A 73-year-old man, with known motor aphasia presented with high fever, dyspnoea, and vomiting. Only after several days it appeared that these signs were due to a sepsis as a consequence of a phlegmon of the neck, caused by an aspired part of his set of false teeth. The delay before diagnosis was due to the fact that adequate medical history taking was difficult because of the aphasia and attempts at non-verbal communication were poorly understood. The localization of the corpus alienum was a second pitfall, because it could not be visualized during physical examination or on the initial chest X-ray. The increased risk of colonization of dentures with pathogenic micro-organisms in nursing home residents may have played a role in the severe course of this infection. This case illustrates the diagnostic problems that may exist in patients who are unable to communicate adequately.

This study aimed to examine the possible cross-sectional mediating role of sleep in the relationship of gratitude with depression and anxiety in patients with chronic pain. A total of 224 patients with chronic pain completed structured questionnaires assessing chronic pain, depression and anxiety symptoms, gratitude, and sleep disturbances. Results of multiple regression analyses yielded a modest mediating effect for sleep on the gratitude-depression link whereas a stronger mediating effect was found for sleep on the gratitude-anxiety link. These data show much of the effect of gratitude on depression was direct whereas sleep exerted a stronger mediating effect on the gratitude-anxiety link.

C. pyloridis colonization was investigated in a selected group of 58 patients with upper gastrointestinal disorders submitted to endoscopy and biopsy. The following results were registered. C. pyloridis was isolated in 14 out of 18 cases of active chronic gastritis, in 15 out of 24 cases of non active chronic gastritis, and 7 out of 8 cases of antral ulceration. A negative finding was registered in 8 patients whose gastric mucosa was normal. Therefore, the Authors consider as valid the etiopathogenetic correlation between C. pyloridis and ulcerative or non-ulcerative chronic gastric diseases, suggested by others.

[Purpose] To report the effects of ankle balance taping for a patient with chronic ankle instability (CAI). [Subject] A 33-year-old man with a 10 year history of chronic ankle stability. [Methods] ABT with kinesiology tape was performed for 2 months (average, 16 h/day) around the right ankle. [Results] At the end of two months, no ankle instability was noted when ascending and descending the stairs, jumping, turning, operating the pedals while driving, and lifting heavy objects. [Conclusion] The repeated use of kinesiology tape in ankle balance taping may be an effective treatment for recovering the ankle stability of patients with chronic ankle instability.

In the clinical routine examination of patients with brain tumors, aphasic symptoms are often not recognized. In order to document the incidence of such symptoms, three diagnostic methods of testing for aphasia were compared: the Aachen aphasia test (AAT), which is the German standard aphasia test, clinical examination, and the Aachen aphasia bedside test (AABT), which was designed to test patients in the acute phases of illness. In the AAT, 50% of patients with left-sided tumors and 36% of those with right-sided tumors showed aphasic disturbances. The AAT results were defined as the gold standard. Clinical examination showed only low sensitivity; less than half of the aphasic patients were diagnosed as such. The AABT also detected only about half of the patients with aphasic disturbances. The low sensitivity is caused mainly by the results of the patients with right-hemisphere tumors, in which the mental set of the examiner during clinical examination (aphasic symptoms are not expected in patients with right-hemisphere lesions) and the pattern of disturbances in the AABT (deficits may be less severe and different in nature) may prevent detection of aphasic symptoms. Both clinical examination and AABT are thus not suitable for aphasia diagnostics in brain tumor patients. As the AAT is very time-consuming in everyday clinical routine, however, the development of an aphasia screening test seems desirable.

Background: Epidemiologic and physiologic studies suggest an association between gastroesophageal reflux disease (GERD) and chronic cough. However, the benefit of antireflux therapy for chronic cough remains unclear, with most relevant trials reporting negative findings. This systematic review aimed to reevaluate the response of chronic cough to antireflux therapy in trials that allowed us to distinguish patients with or without objective evidence of GERD. Methods: PubMed and Embase systematic searches identified clinical trials reporting cough response to antireflux therapy. Datasets were derived from trials that used pH-metry to characterize patients with chronic cough. Results: Nine randomized controlled trials of varied design that treated patients with acid suppression were identified (eight used proton pump inhibitors [PPIs], one used ranitidine). Datasets from two crossover studies showed that PPIs significantly improved cough relative to placebo, albeit only in the arm receiving placebo first. Therapeutic gain in seven datasets was greater in patients with pathologic esophageal acid exposure (range, 12.5%-35.8%) than in those without (range, 0.0%-8.6%), with no overlap between groups. Conclusions: A therapeutic benefit for acid-suppressive therapy in patients with chronic cough cannot be dismissed. However, evidence suggests that rigorous patient selection is necessary to identify patient populations likely to be responsive, using physiologically timed cough events during reflux testing, minimal patient exclusion because of presumptive alternative diagnoses, and appropriate power to detect a modest therapeutic gain. Only then can we hope to resolve this vexing clinical management problem. PMID:23117307

ABSTRACT Objective: To explore the treatment response, tolerability and safety of once-monthly paliperidone palmitate (PP1M) in non-acute patients switched from oral antipsychotics, stratified by time since diagnosis as recently diagnosed (≤3 years) or chronic patients (>3 years). Research design and methods: Post hoc analysis of a prospective, interventional, single-arm, multicentre, open-label, 6-month study performed in 233 recently diagnosed and 360 chronic patients. Main outcome measures: The proportion achieving treatment response (defined as ≥20% improvement in Positive and Negative Syndrome Scale [PANSS] total score from baseline to endpoint) and maintained efficacy (defined as non-inferiority in the change in PANSS total score at endpoint [Schuirmann’s test]). Results: 71.4% of recently diagnosed and 59.2% of chronic patients showed a ≥20% decrease in PANSS total score (p = 0.0028 between groups). Changes in PANSS Marder factors, PANSS subscales, and the proportion of patients with a Personal and Social Performance scale (PSP) total score of 71–100 were significantly greater in recently diagnosed compared with chronic patients. PP1M was well tolerated, presenting no unexpected safety findings. Conclusion: These data show that recently diagnosed patients treated with PP1M had a significantly higher treatment response and improved functioning, as assessed by the PSP total score, than chronic patients.

Chronically critically ill patients often undergo prolonged mechanical ventilation. The role of noninvasive ventilation (NIV) during weaning of these patients remains unclear. The aim of this study was to determine the value of NIV and whether a parameter can predict the need for NIV in chronically critically ill patients during the weaning process. We conducted a prospective study that included chronically critically ill patients admitted to Spanish respiratory care units. The weaning method used consisted of progressive periods of spontaneous breathing trials. Patients were transferred to NIV when it proved impossible to increase the duration of spontaneous breathing trials beyond 18 h. 231 chronically critically ill patients were included in the study. 198 (85.71%) patients achieved weaning success (mean weaning time 25.45±16.71 days), of whom 40 (21.4%) needed NIV during the weaning process. The variable which predicted the need for NIV was arterial carbon dioxide tension at respiratory care unit admission (OR 1.08 (95% CI 1.01-1.15), p=0.013), with a cut-off point of 45.5 mmHg (sensitivity 0.76, specificity 0.67, positive predictive value 0.76, negative predictive value 0.97). NIV is a useful tool during weaning in chronically critically ill patients. Hypercapnia despite mechanical ventilation at respiratory care unit admission is the main predictor of the need for NIV during weaning.

The purpose of this study was to determine whether chronic periodontitis can stand behind modifications in the salivary and blood concentration of some bivalent cations (Calcium, Magnesium, Zinc and Copper). For this purpose, we formed a group of 30 adult patients with clinically onset chronic periodontitis, and another one of 30 healthy patients as control. Both groups were free from acute oral pathology and general illnesses. The groups were divided again according to the habit of smoking. Total saliva samples were obtained as "first time in the morning", then weighed and processed. Cations were read on Atomic Absorption Spectrophotometer and by Ion Chromatography (Magnesium). The same patients were required to undergo laboratory blood tests for Calcium, Magnesium and Zinc. Data obtained was normalised, then statistically interpreted using two-tailed heteroscedastic t-Student tests. Our data confirmed the existence of a connection between salivary calcium, magnesium, zinc and copper, and of blood magnesium, and chronic periodontitis. Salivary calcium and magnesium are affected by smoking.

We present a case of bronchocentric granulomatosis in a woman with no history of asthma who was colonised with Aspergillusfumigatus. A family history of chronic granulomatous disease prompted further testing that demonstrated severely depressed neutrophil oxidant production and gp91phox deficiency compatible with the X linked carrier state of chronic granulomatous disease. Only one report of the association of these two rare diseases has previously appeared in the literature. We postulate that an ineffective immune response led to the prolonged colonisation of Afumigatus resulting in a hypersensitivity reaction that was manifest clinically as bronchocentric granulomatosis.

The status of salivary glands and oral mucous membrane was investigated in 50 patients with chronic active hepatitis against the background of chronic alcoholism. The check up disclosed sialadenosis in 38% of patients and in 54% of patients - such diseases of oral mucous membrane as stomatitis, candidosis and geographic tonque. Besides there were disclosed such disturbances as big and small salivary glands secretion reduction, mixed saliva viscosity increase, increase of protein, P, K, Na and catalase content in it, glycogen hyperaccumulation in gingival tissues. The received data indicated the necessity of dispensary supervision of such patients and their treatment in stomatologist.
The American Academy of Periodontology has developed the following parameter on occlusal traumatism in patients with chronic periodontitis. Occlusal therapy is an integral part of periodontal therapy. Patients should be informed about the occlusal problem, therapeutic alternatives, potential complications, expected results, and their responsibility in treatment. Consequences of no treatment should be explained. Failure to treat occlusal traumatism appropriately in patients with chronic periodontitis may result in progressive loss of bone and an adverse change in prognosis, and could result in tooth loss. Given this information, patients should then be able to make informed decisions regarding their periodontal therapy.

The article summarizes the results of the clinical trials on application of likoprofit in patients with a chronic prostatitis and prostate adenoma, which were conducted by the Russian urologists for the last 8 years. Application of likoprofit in patients after TURP contributes to significantly earlier and effective restoration of microcirculation, which decreases the risk of development of postoperative complications and accelerates rehabilitation of patients. Studies in which likoprofit was applied in patients with a chronic prostatitis and prostate adenoma, proved that likoprofit also has antiedematous effect, improves the urination act, improves ejaculate parameters, positively impacts on sexual function, and has a high safety profile.

Halotherapy was used for sanatorium rehabilitation in 29 patients with chronic obstructive pulmonary diseases (chronic bronchitis and asthma). Significant positive effects of this method resulted in the improvement of the flow-volume parameters curve of lung function and in hypotensive effects on blood pressure. Halotherapy is recommended for use in patients suffering from chronic obstructive pulmonary diseases with hypertension or coronary heart disease.

Low back pain has a life time prevalence of 70% to 85%. Approximately 10% to 20% of all patients experience recurrent episodes or develop chronic low back pain. Sociodemographic, clinical, and psychological characteristics explain the transition from acute to chronic low back pain only to a limited extent. Altered central pain processing may be a contributing mechanism. The measurement of reflex receptive fields (RRF) is a novel method to assess altered central pain processing. The RRF area denotes the area of the foot sole from which spinal nociceptive reflexes can be elicited. It was shown to be enlarged in patients with acute and chronic low back pain compared with pain-free individuals. The aim of the study was to explore the discriminative ability of the RRF to distinguish patients with acute and chronic low back pain with the hypothesis that enlarged RRF are associated with chronic low back pain. We included 214 patients with either acute or chronic low back pain and compared RRF between groups in both univariable and multivariable analyses adjusted for different sociodemographic and clinical characteristics possibly associated with the transition to chronic pain. We found a mean difference between patients with acute and chronic low back pain of -0.01 (95% confidence interval [CI], -0.06 to 0.04) in the crude, -0.02 (95% CI, -0.08 to 0.04) in the age and sex adjusted, and -0.02 (95% CI, -0.09 to 0.05) in the fully adjusted model. Our results suggest that the enlargement of RRF area may not be associated with the transition from acute to chronic low back pain.

Adherence is considered an extremely important virulence factor in yeast. Objective The aim of this study was to analyze the adherence to epithelial cells of C. albicans isolated from patients with chronic periodontitis in comparison to healthy patients. Material and methods Candida albicans cells isolated from individuals with chronic periodontitis (n=25) and healthy controls (n=25) were included in this study. Suspensions of C. albicans (106 cells/mL) and epithelial cells (105 cells/mL) were mixed and incubated at 37ºC for 1 h. The number of yeasts adhered to 25 epithelial cells was counted. Results The number of C. albicans cells adhered to epithelial cells was statistically higher in the chronic periodontitis group than in the control group (Student's t-test, p=0.000). Conclusion The results of the present study suggest a higher Candida adherence of samples isolated from patients with chronic periodontitis. PMID:21710096

Peritonitis is a leading complication of chronic ambulatory peritoneal dialysis. However, very rarely does Neisseria mucosa cause peritonitis. We describe an unusual case of N. mucosa peritonitis in a chronic ambulatory peritoneal dialysis patient. A 28-year-old Hispanic male presents with diffuse abdominal pain exacerbated during draining of the peritoneal fluid. Peritoneal fluid examination was remarkable for leukocytosis and gramnegative diplococci. Bacterial cultures were positive for N. mucosa growth. The patient was treated with ciprofloxacin with preservation of the dialysis catheter. This case highlights the rarity and importance of Neisseria mucosa causing peritonitis in chronic ambulatory peritoneal dialysis patients’. There seems to be a unique association between N. mucosa peritonitis and chronic ambulatory peritoneal dialysis patients’. The patient was successfully managed with ciprofloxacin along with salvaging of the dialysis catheter. PMID:28191300

OBJECTIVE: To test the efficacy of a graded aerobic exercise programme in the chronic fatigue syndrome. DESIGN: Randomised controlled trial with control treatment crossover after the first follow up examination. SETTING: Chronic fatigue clinic in a general hospital department of psychiatry. SUBJECTS: 66 patients with the chronic fatigue syndrome who had neither a psychiatric disorder nor appreciable sleep disturbance. INTERVENTIONS: Random allocation to 12 weeks of either graded aerobic exercise or flexibility exercises and relaxation therapy. Patients who completed the flexibility programme were invited to cross over to the exercise programme afterwards. MAIN OUTCOME MEASURE: The self rated clinical global impression change score, "very much better" or "much better" being considered as clinically important. RESULTS: Four patients receiving exercise and three receiving flexibility treatment dropped out before completion. 15 of 29 patients rated themselves as better after completing exercise treatment compared with eight of 30 patients who completed flexibility treatment. Analysis by intention to treat gave similar results (17/33 v 9/33 patients better). Fatigue, functional capacity, and fitness were significantly better after exercise than after flexibility treatment. 12 of 22 patients who crossed over to exercise after flexibility treatment rated themselves as better after completing exercise treatment 32 of 47 patients rated themselves as better three months after completing supervised exercise treatment 35 of 47 patients rated themselves as better one year after completing supervised exercise treatment. CONCLUSION: These findings support the use of appropriately prescribed graded aerobic exercise in the management of patients with the chronic fatigue syndrome. PMID:9180065

While well validated algorithms exist for the diagnosis of patients with acute dyspnoea, such generally valid procedural instructions are lacking for patients with chronic dyspnoea. The diagnostic approach presented here is based on investigations of 246 patients with chronic dyspnoea recruited from two cardiological practices using a self-developed multi-level procedure. Besides anamnestic and clinical examinations, different diagnostic procedures, available in the ambulant range, are included. The results suggest that in over 50 % of the cases the cause of chronic dyspnoea can be determined from anamnestic and clinical examinations as well as from electrocardiogram and echocardiography. Additional inclusion of lung function and capillary blood gas analysis permitted a sufficient clarification in over 80 % of the cases. In a further step, cardiopulmonary exercise testing clarified the reasons for chronic dyspnoea in approximately 10 % of the remaining patients. Threshold values of lung function parameters as used for the differentiation of acute dyspnoea, do not seem suitable for the diagnosis of patients with chronic dyspnoea. By means of a simple step-wise diagnostic algorithm, applicable under ambulant conditions, the cause of chronic dyspnoea could sufficiently be clarified in more than 95 % of the cases.

Hepatitis B, as a chronic disorder that may be associated with several psychiatric disorders, such as depression, and decrease quality of life of affected patients. One of the most important consequences of psychiatric problems is reduced patient compliance with prolonged therapeutic regimens. Psychotherapy, such as solution- focused therapy, may help these patients to resolve psychiatric problems, increase quality of life and completion of therapeutic regimens. Solution-focused therapy is effective for patients when developing effective coping responses to the stressors associated with chronic diseases. In this study, the process and effects of solution-focused therapy on depression of 2 patients with chronic hepatitis B have been described. They received solution focused therapy for 5 sessions, each session 1 hour once a week. This technique was helpful to decrease symptoms and signs of depression within 5 weeks.

A comprehensive treatment with Likopid of chronic generalized parodontitis in 114 elderly and senile patients was carried out. The state of mechanisms of innate immunity (phagocytosis mechanisms) as well as the profile of proinflammatory cytokines was assessed. The effect of antibiotic-resistant strains of prior microflora on the combined therapy of patients of different age with chronic generalized parodontitis was studied. It is established that due to presence of various types of opportunistic pathogens in patients of different age with parodontitis using the prophylactic antibiotics for the empirical (to determine the antibiotic resistance), a combination of Metronidazole and Lincomycin with the mandatory appointment of immunomodulatory drugs for activation of monocyte-phagocytic system of the patient elderly is most advisable. Use of the drug , "Likopid" significantly improves the results of treatment the elderly and old patients with chronic generalized parodonthitis.

Background Chronic use of tyrosine kinase inhibitor (TKI) may lead to previously unrecognized adverse events. We evaluated the incidence of acute kidney injury (AKI) and chronic kidney disease (CKD) in chronic phase (CP) chronic myeloid leukemia (CML) patients treated with imatinib, dasatinib and nilotinib. Methods Four hundred and sixty-eight newly diagnosed CP CML patients treated with TKIs were analyzed. Molecular and cytogenetic response data, creatinine, glomerular filtration rate (GFR) were followed from start of therapy to last follow-up (median 52 months). GFR was estimated using the Modification of Diet in Renal Disease (MDRD) equation. Results Nineteen patients (4%) had TKI-associated AKI. Imatinib was associated with higher incidence of AKI compared to dasatinib and nilotinib (p=0.014). 58 patients (14%) developed CKD while receiving TKI, 49 of them (84%) while treated with imatinib (p<0.001). Besides imatinib, age, history of hypertension and diabetes mellitus were also associated with development of CKD. In patients with no CKD at baseline, imatinib was shown to decrease GFR overtime. Interestingly, imatinib did not cause significant decline in GFR of patients with history of CKD. Imatinib, dasatinib and nilotinib increased mean GFR after three months of treatment, and nilotinib led with the most significant increase (p<0.001). Acute or chronic kidney disease had no significant impact on overall cytogenetic and molecular response rates or survival. Conclusion Administration of TKI may be safe in the setting of CKD in CP CML patients, but close monitoring is still warranted. PMID:26217876

Clinically, we know that some aphasic patients can sing well despite their speech disturbances. Herein, we report 10 patients with non-fluent aphasia, of which half of the patients improved their speech function after singing training. We studied ten patients with non-fluent aphasia complaining of difficulty finding words. All had lesions in the left basal ganglia or temporal lobe. They selected the melodies they knew well, but which they could not sing. We made a new lyric with a familiar melody using words they could not name. The singing training using these new lyrics was performed for 30 minutes once a week for 10 weeks. Before and after the training, their speech functions were assessed by language tests. At baseline, 6 of them received positron emission tomography to evaluate glucose metabolism. Five patients exhibited improvements after intervention; all but one exhibited intact right basal ganglia and left temporal lobes, but all exhibited left basal ganglia lesions. Among them, three subjects exhibited preserved glucose metabolism in the right temporal lobe. We considered that patients who exhibit intact right basal ganglia and left temporal lobes, together with preserved right hemispheric glucose metabolism, might be an indication of the effectiveness of singing therapy.

Chronic lower back pain is one of the most common musculoskeletal problems; it is also the most expensive industrial injury. Not surprisingly, many treatments have been developed to combat this expensive and debilitating condition. One of these, intradiscal electrothermal treatment (IDET), was developed for patients with chronic discogenic lower back pain who failed to improve with any of the wide variety of non-surgical treatments. The present study sought to evaluate the efficacy of IDET for patients with chronic lower back pain. Twenty-five patients were enrolled in this prospective study; the patients received IDET between June 2001 and June 2003. MRI was used to confirm the diagnosis of internal disc disruption in all patients. The patients then underwent a pre-operative provocative test and discography. The follow-up duration was at least 1 year in all cases, and the visual analogue scale, recovery rate, and satisfaction of each patient were evaluated. The average age of the patients was 32 years (age range 18 to 49 years), and the patient group was 33% male and 67% female. Of the 25 patients, 5 underwent lumbar fusion surgery within 1 year of IDET. After IDET, 8 patients (32%) reported more pain than before, 14 patients (56%) reported less pain, and 3 patients (12%) experienced no change. Twelve patients (48%) were satisfied with IDET, 11 (44%) were dissatisfied, and 2 (8%) were undecided about the treatment. At least 1 year after IDET, nearly half the study patients were dissatisfied with their medical outcome. Consequently, 5 patients (20%) underwent fusion surgery at 1 year after IDET. Although other studies have shown good results with IDET for at least 2 years, this investigation suggests the IDET may be somewhat less effective. In order to firmly establish the efficacy of IDET for treating chronic discogenic lower back pain, additional studies with larger numbers of patients evaluated over longer time periods are recommended.

ABSTRACT The aim of this study was to explore the prevalence and relationship of anticipated chronic illness stigma among patients diagnosed with a variety of chronic diseases in three Southeast Asian countries (Cambodia, Myanmar and Vietnam). A cross-sectional survey was conducted in 4,803 adult chronic disease patients (mean age 49.3 years; SD=16.5) recruited systematically from health facilities. Overall, the results indicate that 20.7% of patients reported that for any of the 12 stigma items, they anticipated they were likely or very likely to experience chronic disease stigma. A multivariate analysis of sociodemographics revealed the following were associated with anticipated chronic disease stigma: older versus younger age, OR (odds ratio) = 0.71; 95% Confidence Interval (CI) [0.58, 0.87]; higher versus lower education, OR = 2.23; 95% CI [1.81, 2.75]; origin from Myanmar or Vietnam, being single, divorced or widowed, rural residence, and health status (having three or more chronic conditions versus having one chronic condition), OR = 1.93; 95% CI [1.58, 2.35]; lower versus higher quality of life, OR = 0.73; 95% CI [0.63, 0.85]); health risk behavior (physical inactivity, poor diet, current smoking, and problem drinking) and low versus medium or high medication adherence (OR = 0.69; 95% CI [0.55,0.86]). This study demonstrated the possible consequences of anticipated stigma on the health and behavior of people living with chronic diseases, and several factors for chronic disease stigma were identified that can help guide interventions to reduce chronic illness stigma in this population.

Background: Chronic pulmonary infection with transmissible Pseudomonas aeruginosa strains in individuals with cystic fibrosis (CF) has been reported, raising issues of cross infection and patient segregation. The first such strain to be described (the Liverpool epidemic strain, LES) is now widespread in many UK CF centres. However, whether such infection carries a worse prognosis is unknown. To address this, the clinical course of a group of CF patients chronically infected by LES was compared with that in patients harbouring unique strains. Methods: Using P aeruginosa strain genotyping, two cohorts of CF patients attending the Liverpool CF service were identified who were LES positive or negative in 1998 and remained so until 2002. From these, two groups of 12 patients were matched in 1998 for age, spirometric parameters, and nutritional state and their clinical course was followed for 5 years. Patients chronically infected with Burkholderia cepacia were excluded. Results: Patients chronically infected with LES had a greater annual loss of lung function than those not chronically infected by LES (mean difference between groups -4.4% (95% CI -8.1 to -0.9; p<0.02)), and by 2002 their percentage predicted forced expiratory volume in 1 second (FEV1) was worse (mean 65.0% v 82.6%, p<0.03). Their nutritional state also deteriorated over the study period (mean difference between groups in body mass index -0.7 (95% CI -1.2 to -0.2; p<0.01)), such that by 2002 they were malnourished compared with LES negative patients (mean BMI 19.4 v 22.7, p<0.02). Conclusions: Chronic infection with the Liverpool epidemic P aeruginosa strain in CF patients confers a worse prognosis than infection with unique strains alone, confirming the need for patient segregation. Since this strain is common in many CF units, strain identification in all CF centres is essential. This can only be carried out using genomic typing methods. PMID:15047956

Low level of blood cholesterol is often found in patients with diseases which pathogenesis is mainly associated with inflamation. To detect blood cholesterol spectre, 383 patients with acute and chronic infections have been observed, level of blood cholesterol of 1259 patients with different pathology was retrospectively analyzed. It was found that an increase in frequency of low cholesterol and decrease in frequency of high cholesterol in patients with diseases not associated with infections do not depend on the age of patients. Extremely low level of cholesterol (Cholesterol < or = 100 mg/dl) is found in 12,8% of patients with inflamation of infectious origion, oftener in patients with community-acquired pneumonia and chronic virus hepatitis. Patients with intestinal infections have extremely low level of cholesterol; two-fold oftener than healthy persons have.

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

The term multimorbidity is usually defined as the coexistence of two or more chronic conditions within an individual, whereas the term comorbidity traditionally describes patients with an index condition and one or more additional conditions. Multimorbidity of chronic conditions markedly worsens outcomes in patients, increases treatment burden and increases health service costs. Although patients with chronic respiratory disease often have physical comorbidities, they also commonly experience psychological problems such as depression and anxiety. Multimorbidity is associated with increased health-care utilisation and specifically with an increased number of prescription drugs in individuals with multiple chronic conditions such as chronic obstructive pulmonary disease. This npj Primary Care Respiratory Medicine Education Section case study involves a patient in a primary care consultation presenting several common diseases prevalent in people of this age. The patient takes nine different drugs at this moment, one or more pills for each condition, which amounts to polypharmacy. The problems related with polypharmacy recommend that a routine medication review by primary care physicians be performed to reduce the risk of adverse effects of polypharmacy among those with multiple chronic conditions. The primary care physician has the challenging role of integrating all of the clinical problems affecting the patient and reviewing all medicaments (including over-the-counter medications) taken by the patient at any point in time, and has the has the key to prevent the unwanted consequences of polypharmacy. Multimorbid chronic disease management can be achieved with the use of care planning, unified disease templates, use of information technology with appointment reminders and with the help of the wider primary care and community teams.

In addition to the debilitating fatigue, the majority of patients with chronic fatigue syndrome (CFS) experience chronic widespread pain. These pain complaints show the greatest overlap between CFS and fibromyalgia (FM). Although the literature provides evidence for central sensitization as cause for the musculoskeletal pain in FM, in CFS this evidence is currently lacking, despite the observed similarities in both diseases. The knowledge concerning the physiological mechanism of central sensitization, the pathophysiology and the pain processing in FM, and the knowledge on the pathophysiology of CFS lead to the hypothesis that central sensitization is also responsible for the sustaining pain complaints in CFS. This hypothesis is based on the hyperalgesia and allodynia reported in CFS, on the elevated concentrations of nitric oxide presented in the blood of CFS patients, on the typical personality styles seen in CFS and on the brain abnormalities shown on brain images. To examine the present hypothesis more research is required. Further investigations could use similar protocols to those already used in studies on pain in FM like, for example, studies on temporal summation, spatial summation, the role of psychosocial aspects in chronic pain, etc. PMID:17115100

Using (11C)-deoxy-D-glucose and positron emission tomography (PET), the authors measured brain metabolism in 18 patients with chronic schizophrenia to assess which of the metabolic measures from two test conditions was more closely related to the patients' differing clinical characteristics. The two conditions were resting and activation, and an eye tracking task was used. Patients with more negative symptoms showed lower global metabolic rates and more severe hypofrontality than did the patients with fewer negative symptoms. Differences among the patients were distinguished by the task: sicker patients failed to show a metabolic activation response. These findings suggest that cerebral metabolic patterns reflect clinical characteristics of schizophrenic patients.

Cycle and treadmill exercise tests are unsuitable for elderly, frail and severely limited patients with heart failure and may not reflect capacity to undertake day-to-day activities. Walking tests have proved useful as measures of outcome for patients with chronic lung disease. To investigate the potential value of the 6-minute walk as an objective measure of exercise capacity in patients with chronic heart failure, the test was administered six times over 12 weeks to 18 patients with chronic heart failure and 25 with chronic lung disease. The subjects also underwent cycle ergometer testing, and their functional status was evaluated by means of conventional measures. The walking test proved highly acceptable to the patients, and stable, reproducible results were achieved after the first two walks. The results correlated with the conventional measures of functional status and exercise capacity. The authors conclude that the 6-minute walk is a useful measure of functional exercise capacity and a suitable measure of outcome for clinical trials in patients with chronic heart failure.

Background Chronic Lyme disease is a term that describes a constellation of persistent symptoms in patients with or without evidence of previous Borrelia burgdorferi infection. Patients labeled as having chronic Lyme disease have a substantial clinical burden. Little is known about chronic Lyme disease patient experiences in the healthcare system and their relationships with healthcare providers. The purpose of this study was to gather insights about the experiences of patients who carry a diagnosis of chronic Lyme disease in the United States healthcare system. Methods Qualitative, phenomenological study in 12 adult participants who identified themselves as having chronic Lyme disease. Semi-structured face-to-face in-depth interviews were conducted, 60–90 minutes in length, focusing on perceptions of disease burden and of their healthcare providers, using the dimensions of the Health Belief Model. Transcribed interviews were analyzed for emergent topics and themes in the categories of beliefs/understanding, personal history/narrative, consequences/limitations, management, and influences on care. Results Enrollment continued until theoretical saturation was obtained. Four major themes emerged from participants’ descriptions of their experiences and perceptions: 1) changes in health status and the social impact of chronic Lyme disease, 2) doubts about recovery and the future, 3) contrasting doctor-patient relationships, 4) and the use of unconventional therapies to treat chronic Lyme disease. Conclusions Participants reported a significant decline in health status associated with chronic Lyme disease and were often unsatisfied with care in conventional settings. Negative experiences were associated with reports of dismissive, patronizing, and condescending attitudes. Positive experiences were associated with providers who were reported to be attentive, optimistic, and supportive. Consultations with CAM practitioners and use of CAM therapies were common. Actively

Myofascial pain, presented as myofascial trigger points (MTrPs)-related pain, is a common, chronic disease involving skeletal muscle, but its underlying mechanisms have been poorly understood. Previous studies have revealed that chronic pain can induce microstructural abnormalities in the cerebral gray matter. However, it remains unclear whether the brain gray matters of patients with chronic MTrPs-related pain undergo alteration. In this study, we employed the Diffusion Kurtosis Imaging (DKI) technique, which is particularly sensitive to brain microstructural perturbation, to monitor the MTrPs-related microstructural alterations in brain gray matter of patients with chronic pain. Our results revealed that, in comparison with the healthy controls, patients with chronic myofascial pain exhibited microstructural abnormalities in the cerebral gray matter and these lesions were mainly distributed in the limbic system and the brain areas involved in the pain matrix. In addition, we showed that microstructural abnormalities in the right anterior cingulate cortex (ACC) and medial prefrontal cortex (mPFC) had a significant negative correlation with the course of disease and pain intensity. The results of this study demonstrated for the first time that there are microstructural abnormalities in the brain gray matter of patients with MTrPs-related chronic pain. Our findings may provide new insights into the future development of appropriate therapeutic strategies to this disease. PMID:28066193

Study Design Preliminary study. Purpose To assess the association of neuropathic pain with chronic low back pain (LBP) and the effect of pregabalin on neuropathic pain in the elderly. Overview of Literature Of those with chronic LBP, 37% were predominantly presenting with neuropathic pain in young adults. Pregabalin is effective for pain in patients with diabetic neuropathy and peripheral neuralgia. No study has reported on the effects of pregabalin for chronic LBP in elderly patients yet. Methods Pregabalin was administered to 32 patients (age, ≥65 years) with chronic LBP for 4 weeks. Pain and activities of daily living were assessed using the Neuropathic Pain Screening Questionnaire (NePSQ), the pain DETECT questionnaire, visual analog scale, the Japanese Orthopedic Association score, the short form of the McGill Pain Questionnaire and the Roland Morris Disability Questionnaire. Modic change and spinal canal stenosis were investigated using magnetic resonance imaging. Results Altogether, 43.3% of patients had neuropathic pain according to the NePSQ and 15.6% patients had pain according to the pain DETECT. The efficacy rate of pregabalin was 73.3%. A significant effect was observed in patients with neuropathic pain after 4 weeks of administration. Conclusions Neuropathic pain was slightly less frequently associated with chronic LBP in the elderly. Pregabalin was effective in reducing pain in patients with chronic LBP accompanied with neuropathic pain. Lumbar spinal stenosis and lower limb symptoms were observed in patients with neuropathic pain. We recommend the use of pregabalin for patients after evaluating a screening score, clinical symptoms and magnetic resonance imaging studies. PMID:25901238

Patients with chronic kidney disease (CKD) experience other diseases such as cardiovascular disease (CVD) and retinopathy. The purpose of this study was to assess whether retinopathy predicts future CVD events in a subgroup of the participants of the Chronic Renal Insufficiency Cohort (CRIC) study. In this ancillary investigation, 2,605 participants of the CRIC study were invited to participate, and nonmydriatic fundus photographs were obtained in 1,936 subjects. Using standard protocols, presence and severity of retinopathy (diabetic, hypertensive, or other) and vessel diameter caliber were assessed at a central photograph reading center by trained graders masked to study participant's information. Patients with a self-reported history of cardiovascular disease were excluded. Incident CVD events were adjudicated using medical records. Kidney function measurements, traditional and nontraditional risk factors, for CVD were obtained. Presence and severity of retinopathy were associated with increased risk of development of any CVD in this population of CKD patients, and these associations persisted after adjustment for traditional risk factors for CVD. We also found a direct relation between increased venular diameter and risk of development of CVD; however, the relation was not statistically significant after adjustment for traditional risk factors. In conclusion, the presence of retinopathy was associated with future CVD events, suggesting that retinovascular pathology may be indicative of macrovascular disease even after adjustment for renal dysfunction and traditional CVD risk factors. Assessment of retinal morphology may be valuable in assessing risk of CVD in patients with CKD, both clinically and in research settings.

The number of individuals seeking treatment for prescription opioid dependence has increased dramatically, fostering a need for research on this population. The aim of this study was to examine reasons for prescription opioid use among 653 participants with and without chronic pain, enrolled in the Prescription Opioid Addiction Treatment Study, a randomized controlled trial of treatment for prescription opioid dependence. Participants identified initial and current reasons for opioid use. Participants with chronic pain were more likely to report pain as their primary initial reason for use; avoiding withdrawal was rated as the most important reason for current use in both groups. Participants with chronic pain rated using opioids to cope with physical pain as more important, and using opioids in response to social interactions and craving as less important, than those without chronic pain. Results highlight the importance of physical pain as a reason for opioid use among patients with chronic pain.

There is a bidirectional relationship between depression and chronic medical disorders. The adverse health risk behaviors and psychobiological changes associated with depression increase the risk for chronic medical disorders, and biological changes and complications associated with chronic medical disorders may precipitate depressive episodes. Comorbid depression is associated with increased medical symptom burden, functional impairment, medical costs, poor adherence to self-care regimens, and increased risk of morbidity and mortality in patients with chronic medical disorders. Depression may worsen the course of medical disorders because of its effect on proinflammatory factors, hypothalamic-pituitary axis, autonomic nervous system, and metabolic factors, in addition to being associated with a higher risk of obesity, sedentary lifestyle, smoking, and poor adherence to medical regimens. Both evidence-based psychotherapies and antidepressant medication are efficacious treatments for depression. Collaborative depression care has been shown to be an effective way to deliver these treatments to large primary care populations with depression and chronic medical illness. PMID:21485743

Recent case reports have shown that hepatitis E virus (HEV) infection can cause chronic hepatitis in immunosuppressed or immunocompromised patients. A 37-year-old woman suffered from prolonged elevation of aminotransferases after chemotherapy for Burkitt's lymphoma and was diagnosed with chronic hepatitis E due to a transfusion during chemotherapy. After an 8-month administration of ribavirin, complete HEV clearance was not achieved, likely due to prolonged hypogammaglobulinemia. This case indicates that HEV infection should be ruled out during liver dysfunction in immunosuppressed or immunocompromised patients and suggests that an alternative therapeutic strategy for such patients will be needed.

This controlled study involving 99 patients with chronic somatic diseases (CSD) had the objective to identify psychological predictors of the efficiency of a new method of psychotherapy, namely autogenous melodeclamation training (AMDT). Dynamics of the psychological status of the patients in the course of therapy was assessed using SMOL test, Spilberger STAI test, overall health-physical activity-mood test, and Beck depression inventory. It was shown that moderately compromised psychological adaptation and minor depressive disorders were the most reliable predictors of marked improvement of the patients' psychological status under effect of autogenous melodeclamation training included in the combined rehabilitative therapy of chronic somatic diseases.

Autopsy data on 24 chronic maintenance hemodialysis patients who had received varying doses of parenteral iron as the iron-dextran complex were reviewed for evidence of iron overload (hemosiderosis) and tissue fibrosis or organ dysfunction (hemochromatosis). Hemosiderosis was frequent in patients who received high total doses of iron but absent in those who received little or no iron. The degree of tissue iron did not increase with increased iron administration above a total of 2.5 g. Hemochromatosis or organ dysfunction secondary to tissue iron deposition was not noted in any patient. Chronic parenteral iron administration may improve anemia and result in tissue iron deposition but does not lead to hemochromatosis.

Chronic diarrhea is one of the most frequent gastro-intestinal manifestations in acquired immunodeficiency syndrome (AIDS). Protozoa and nontuberculous mycobacteria (NTM) are opportunistic pathogens that can easily infect these patients. Among the NTM, Mycobacterium avium complex (MAC) is the most frequently observed pathogen in HIV-infected patients. However, NTMs other than MAC have not been reported as a gastrointestinal pathogen as yet. We present a case of chronic diarrhea in an AIDS patient in whom Mycobacterium ulcerans and cryptosporidium co-infection is evidenced from colonic tissue.

Chronic bisphosphonate therapy is associated with atypical fractures of the subtrochanteric and proximal femoral diaphyseal regions. Various radiologic imaging signs can identify bisphosphonate-associated stress fractures before they progress to complete fractures. Identifying patients who are at risk and modifying treatment can prevent these fractures from occurring. We present a case study of a patient taking bisphosphonate with 2 years of chronic pain, and characteristic clinical signs of bisphosphonate-associated incomplete stress fractures that went untreated until the patient suffered from a right subtrochanteric complete fracture. Our goal is to make physicians aware of the signs of insufficiency fractures associated with chronic bisphosphonate therapy such that appropriate clinical decisions are made to optimize the quality of patient care.

The overall incidence of amiodarone-induced thyroid dysfunction ranges from 2% to 24%. One third to half of patients with hypothyroidism have anemia due to some decrease in normal red blood cell mass and erythropoietin (EPO) resistance. Therefore, for patients with chronic renal disease under medication with amiodarone, early regular thyroid function test should be checked in order to avoid amiodarone-induced hypothyroidism and EPO-resistant anemia. If amiodarone-induced hypothyroidism and EPO-resistant anemia occur in patients with chronic renal failure, early thyroxine should be given instead of waiting for spontaneous recovery by amiodarone discontinuation only. Here, we report a patient with chronic renal failure who developed EPO-resistant anemia after amiodarone treatment for arrhythmia. The hemoglobin level responded to EPO therapy rapidly after thyroxine administration and amiodarone discontinuation.

Web-based self-management interventions (W-SMIs) are designed to help a large number of chronically ill people become more actively engaged in their health care. Despite the potential to engage more patients in self-managing their health, the use of W-SMIs by patients and their clinicians is low. Using a self-management conceptual model based on…

This study was conducted to address possible differences in pathogenesis of chronic pulmonary thromboembolism in comparison with that in acute pulmonary embolism using In-111 labeled platelet scintigraphy. Six patients with acute pulmonary embolism and eight patients with chronic pulmonary embolism were involved in this study. Pulmonary emboli were confirmed by angiography. In each patient, autologous platelets were collected from a venous blood sample of 50 ml and labeled with 18.5 MBq of In-111 chloride using a method previously reported. Whole body and spot view images were obtained at twenty-four hours following intravenous administration of In-111 labeled platelets. Images were interpreted visually by two observers. In acute pulmonary embolism no definite abnormal accumulation was seen in the areas of pulmonary emboli, which was mostly consistent with previously published results. In chronic pulmonary embolism, three out of nine patients (33%) showed tracer accumulation corresponding to the areas of emboli in pulmonary vessels. These patients showed significantly lower arterial oxygen pressure in comparison with other patients without abnormal tracer accumulation. In addition, two of the three chronic patients with positive intrathoracic accumulation showed abnormal tracer uptake in the lower extremities. Surgical thrombectomy confirmed presence of progressive thrombi in the pulmonary arteries in scan positive patients. These results suggest possible mechanisms for thrombus formation and progression in the pulmonary vessels following initial thromboembolic events, which worsen the patient`s condition and cause a prolonged clinical course of pulmonary embolism. In-111 labeled scintigraphy can be used to depict possible thrombus formation in the pulmonary vessels in chronic pulmonary thromboembolic patients, who might require different therapeutic interventions from those for acute pulmonary embolism.

In March 1841, the year before he died of acute stroke, Stendhal, one of the most famous French novelists of the 19th century, developed a series of short-lived speech impairments which he precisely reported in his correspondence. His reports suggest that these spells were aphasic transient ischemic attacks (TIAs). The accuracy and precision of Stendhal's description exactly 20 years before Broca's presentation at the Société d'Anthropologie is remarkable since it occurred at a time when TIAs had not been studied in the medical literature and aphasia was still in its 'prehistory'. Stendhal's TIAs a few months before his fatal stroke constitute the first historical report of the warning nature of TIAs, which would be emphasized only over 100 years later.

A right-handed Japanese crossed Wernicke's aphasic showed complete neologistic jargonagraphia in kanji and kana with anosognosia of his writing deficits. Prominent jargonagraphia in kanji is quite rare and has not been previously described in the literature. Marked dissociation between speaking and writing during the course suggested that his jargonagraphia might be unique to crossed aphasia. His condition was interpreted for the main part by Yokoyama, Okubo, Doseki, and Yamadori's hypothesis (1981) that free-running on of motor engrams of characters stored in the left hemisphere caused jargonagraphia in crossed aphasia. This case of jargonagraphia in kanji suggests that this hypothesis should be supplemented by the following points: (1) in kanji, not necessarily a character as a whole, but radicals or parts of radicals, function as motor units, which may be released to produce jargonagraphia in kanji; (2) free-running on of visual images as well as of kinesthetic images should be considered especially in written jargon in kanji.

The effect of an instructional package, which included modeling, reinforcement, and remedial feedback on the rate, accuracy, and topography of sentences composed by four hearing impaired and aphasic children, was examined. In a specially designed classroom, students wrote sentences describing a stimulus picture on acetate sheets placed on the stage of an overhead projector which was built into each student's desk. This arrangement provided the teacher and other students immediate and continuous visual access to each student's sentences. In a multiple baseline design across behaviors, model sentences were projected and token reinforcment and remedial feedback were made contingent upon writing correct sentences containing prenominal adjectives only, then adverbs only, then prenomial adjectives plus adverbs. During baseline all student displayed poor written language skills and seldom wrote sentences containing modifiers. When the instructional package was implemented, all students demonstrated significant increases in response rate, accuracy, and percentage of correct sentences including prenominal adjectives and adverbs.

Background The burden of disease due to norovirus infection has been well described in the general United States population, but studies of norovirus occurrence among persons with chronic medical conditions have been limited mostly to the immunocompromised. We assessed the impact of norovirus gastroenteritis on health care utilization in US subjects with a range of chronic medical conditions. Methods We performed a retrospective cohort study using MarketScan data from July 2002 to December 2013, comparing the rates of emergency department visits, outpatient visits and hospitalizations among patients with chronic conditions (renal, cardiovascular, respiratory, immunocompromising, gastrointestinal, hepatic/pancreatic and neurological conditions and diabetes) with those in a healthy population. We estimated the rates of these outcomes due to norovirus gastroenteritis using an indirect modelling approach whereby cases of gastroenteritis of unknown cause and not attributed to a range of other causes were assumed to be due to norovirus. Results Hospitalization rates for norovirus gastroenteritis were higher in all of the risk groups analyzed compared with data in otherwise healthy subjects, ranging from 3.2 per 10,000 person-years in persons with chronic respiratory conditions, to 23.1 per 10,000 person-years in persons with chronic renal conditions, compared to 2.1 per 10,000 among persons without chronic conditions. Over 51% of all norovirus hospitalizations occurred in the 37% of the population with some form of chronic medical condition. Outpatient visits for norovirus gastroenteritis were also increased in persons with chronic gastrointestinal or immunocompromising conditions. Conclusion Norovirus gastroenteritis leads to significantly higher rates of healthcare utilization in patients with a chronic medical condition compared to patients without any such condition.

Currently, the definitive diagnosis of chronic compartment syndrome is based on invasive measurements of intracompartmental pressure. We measured the intramuscular pressure and the relative oxygenation in the anterior compartment of the leg in eighteen patients who were suspected of having chronic compartment syndrome as well as in ten control subjects before, during, and after exercise. Chronic compartment syndrome was considered to be present if the intramuscular pressure was at least fifteen millimeters of mercury (2.00 kilopascals) before exercise, at least thirty millimeters of mercury (4.00 kilopascals) one minute after exercise, or at least twenty millimeters of mercury (2.67 kilopascals) five minutes after exercise. Changes in relative oxygenation were measured with use of the non-invasive method of near-infrared spectroscopy. In all patients and subjects, there was rapid relative deoxygenation after the initiation of exercise, the level of oxygenation remained relatively stable during continued exercise, and there was reoxygenation to a level that exceeded the pre-exercise resting level after the cessation of exercise. During exercise, maximum relative deoxygenation in the patients who had chronic compartment syndrome (mean relative deoxygenation [and standard error], -290 +/- 39 millivolts) was significantly greater than that in the patients who did not have chronic compartment syndrome (-190 +/- 10 millivolts) and that in the control subjects (-179 +/- 14 millivolts) (p < 0.05 for both comparisons). In addition, the interval between the cessation of exercise and the recovery of the pre-exercise resting level of oxygenation was significantly longer for the patients who had chronic compartment syndrome (184 +/- 54 seconds) than for the patients who did not have chronic compartment syndrome (39 +/- 19 seconds) and the control subjects (33 +/- 10 seconds) (p < 0.05 for both comparisons).

Background It is widely recognized that both doctors and patients report discontent regarding pain management provided and received. The impact of chronic pain on an individual’s life resonates beyond physical and mental suffering; equal or at times even greater impact is observed on an individual’s personal relationships, ability to work, and social interactions. The degree of these effects in each individual varies, mainly because of differences in biological factors, social environment, past experiences, support, and belief systems. Therefore, it is equally possible that these individual patient characteristics could influence their treatment outcome. Research shows that meeting patient expectations is a major challenge for health care systems attempting to provide optimal treatment strategies. However, patient perspectives and expectations in chronic pain management have not been studied extensively. The aim of this study is to investigate the views, perceptions, beliefs, and expectations of individuals who experience chronic pain on a daily basis, and the strategies used by them in managing chronic pain. This paper describes the study protocol to be used in a cross sectional survey of chronic pain patients. Methods and analysis The study population will comprise of individuals aged ≥18 years, who have experienced pain for ≥3 months with no restrictions of sex, ethnicity, or region of residence. Ethics approval for our study was obtained from Humans research ethics committees, University of Adelaide and University of South Australia. Multinomial logistic regression will be used to estimate the effect of duration and character of pain, on patient’s perception of time to recovery and supplement intake. Logistic regression will also be used for estimating the effect of patient-provider relationship and pain education on patient-reported recovery and pain intensity. Discussion Knowledge about the perceptions and beliefs of patients with chronic pain could
Objective: The aim of this study is to assess the impact of health education on diet, smoking and exercise among patients with chronic diseases (coronary artery disease, hypertension and type 2 diabetes mellitus) in Al Qassim Region in Saudi Arabia. Methods: We used data from a clustered experimental study in selected primary health care (PHC) centers in Al-Qassim. The study was conducted during January to October 2009 to assess the impact of an enhanced health education program on smoking, diet and exercise. The intervention comprised refresher training of PHC centers’ staff to improve communication skills and use of health education materials. Special health education sessions in the PHC centers were also organized with the help of medical students from Qassim University. Target population included patients of chronic diseases as well as patients visiting for other complaints. Baseline and end-line surveys were conducted to assess the impact of health education program on the prevalence of smoking, unhealthy diet and physical inactivity. The sample size was estimated to detect the impact of health education on these risk factors. Data were analyzed using SPSS (version 11.5) to conduct multivariate analysis to assess the impact of health education among chronic disease patients. Results: At baseline, chronic disease patients had generally healthier diet and did more exercise than patients of other diseases. Among chronic disease patients, significant improvements in smoking, diet and exercise habits were observed at end-line survey compared to baseline. These changes persisted after controlling for age, sex, marital status and education. Conclusion: We conclude that health education for patients visiting the PHC centers for follow-up of chronic diseases will significantly improve compliance to doctor’s advice regarding smoking, diet and exercise.

Improving access to care, health outcomes, and patient satisfaction are primary objectives for healthcare practices. This article outlines benefits, concerns, and possible challenges of shared medical appointments (SMAs) for patients and providers. The SMA model was designed to support providers' demanding schedules by allowing patients with the same chronic condition to be seen in a group setting. By concentrating on patient education and disease management, interactive meetings provide an opportunity for patients to share both successes and struggles with others experiencing similar challenges. Studies demonstrated that SMAs improved patient access, enhanced outcomes, and promoted patient satisfaction. This article describes the potential benefits of SMAs for patients with chronic heart disease, which consumes a large number of healthcare dollars related to hospital admissions, acute exacerbations, and symptom management. Education for self-management of chronic disease can become repetitive and time consuming. The SMA model introduces a fresh and unique style of healthcare visits, allowing providers to devote more time and attention to patients and improve productivity. The SMA model provides an outstanding method for nurse practitioners to demonstrate their role as a primary care provider, by leading patients in group discussions and evaluating their current health status. Patient selection, preparation, and facilitation of an SMA are discussed to demonstrate the complementary nature of an SMA approach in a healthcare practice.

Characteristic of oral microflora in practically sound children and patients with chronic gastroduodenitis was offered. Microflora singled out from ill persons differed by pathogenicity in previously opportunistic pathogenic forms. Monitoring of sensitivity and resistivity to antibiotics of the singled out microflora in practically sound children and ill with chronic gastroduodenitis was presented. When treating oral diseases one should take into account the high resistivity to antibiotics (especially to benzilpenicillin) of opportunistic pathogenic forms.

Background Chronic pain and its associated distress and disability are common reasons for seeking medical help. Patients with chronic pain use primary healthcare services five times more than the rest of the population. Mindfulness has become an increasingly popular self-management technique. Aim To assess the effectiveness of mindfulness-based interventions for patients with chronic pain. Design and setting Systematic review and meta-analysis including randomised controlled trials of mindfulness-based interventions for chronic pain. There was no restriction to study site or setting. Method The databases MEDLINE®, Embase, AMED, CINAHL, PsycINFO, and Index to Theses were searched. Titles, abstracts, and full texts were screened iteratively against inclusion criteria of: randomised controlled trials of mindfulness-based intervention; patients with non-malignant chronic pain; and economic, clinical, or humanistic outcome reported. Included studies were assessed with the Yates Quality Rating Scale. Meta-analysis was conducted. Results Eleven studies were included. Chronic pain conditions included: fibromyalgia, rheumatoid arthritis, chronic musculoskeletal pain, failed back surgery syndrome, and mixed aetiology. Papers were of mixed methodological quality. Main outcomes reported were pain intensity, depression, physical functioning, quality of life, pain acceptance, and mindfulness. Economic outcomes were rarely reported. Meta-analysis effect sizes for clinical outcomes ranged from 0.12 (95% confidence interval [CI] = −0.05 to 0.30) (depression) to 1.32 (95% CI = −1.19 to 3.82) (sleep quality), and for humanistic outcomes 0.03 (95% CI = −0.66 to 0.72) (mindfulness) to 1.58 (95% CI = −0.57 to 3.74) (pain acceptance). Studies with active, compared with inactive, control groups showed smaller effects. Conclusion There is limited evidence for effectiveness of mindfulness-based interventions for patients with chronic pain. Better-quality studies are required. PMID

This study analyses the relationships between patients' dispositional optimism and pessimism and the coping strategies they use. In addition, the coping strategies repercussions on adjustment to chronic pain were studied. Ninety-eight patients with heterogeneous chronic pain participated. The assessment tools were as follows: Life Orientation Test (LOT), the Vanderbilt Pain Management Inventory (VPMI), the McGill Pain Questionnaire (MPQ), Hospital Anxiety and Depression Scale (HADS), and the Impairment and Functioning Inventory for Chronic Pain Patients (IFI). The hypothetical model establishes positive relationships between optimism and the use of active coping strategies, whereas pessimism is related to the use of passive coping. Active coping is associated with low levels of pain, anxiety, depression and impairment and high levels of functioning. However, passive coping is related to high levels of pain, anxiety, depression and impairment and low levels of functioning. The hypothetical model was empirically tested using the LISREL 8.20 software package and the unweighted least squares method. The results support the hypotheses formulated regarding the relations among optimism, pessimism, coping and adjust of chronic pain patients. By analysing optimism among chronic pain patients, clinicians could make better predictions regarding coping and adjustment.

The objective of this study was to demonstrate efficacy, benefit, and potential use of topiramate in treating obese patients with chronic low back pain. This is a case report from an outpatient academic pain multidisciplinary clinical center. The patient was a 30-year-old morbidly obese (body mass index [BMI]: 61.4 kg/m(2)) female suffering from chronic low back pain. With a known association between obesity and chronic low back pain, and a possible role of topiramate in treating both simultaneously, the patient was started on a therapeutic trial of topiramate. Over a period of a 12-week topiramate therapy, the patient experienced clinically meaningful and significant weight loss as well as improvement in her chronic low back pain and functionality. With more substantial evidence, pain physicians may start considering using topiramate in the multimodal management of obesity-related chronic low back pain based on their thoughtful consideration of the drug's efficacy and side effects and the patient's comorbidities and preferences.

The liver biopsy has long been the "gold standard" for assessing liver fibrosis in patients with hepatitis C. It's an invasive procedure which is associated with an elevated bleeding, especially in chronic hemodialysis patients. Main goal is to assess liver fibrosis in chronic hemodialysis with HCV by Fibroscan and by biological scores (APRI, Forns and Fib-4), and to measure the correlation between these tests. Cross-sectional study including all chronic hemodialysis patients with hepatitis C virus, in two public hemodialysis centers of Fez. All patients were evaluated for liver fibrosis using noninvasive methods (FibroScan and laboratory tests). Subsequently, the correlation between different tests has been measured. 95 chronic hemodialysis were studied, twenty nine patients (30.5%) with chronic hepatitis C. The average age was 52.38 ± 16.8 years. Nine liver fibrosis cases have been concluded by forns score. Fibroscan has objectified significant fibrosis in 6 cases. On the other side APRI has objectified sgnifivant fibrosis only in 3 cases. The Fib-4 showed severe fibrosis in five cases. The results have been most consistent between APRI and Fib-4, followed by Fibroscan and Forns, then APRI and FibroScan. PMID:26958136

Background. The contribution of apathy, frequently recognized in individuals with neurodegenerative diseases, to chronic low back pain (LBP) remains unclear. Objectives. To investigate levels of apathy and clinical outcomes in patients with chronic LBP treated with tramadol-acetaminophen. Methods. A retrospective case-control study involving 73 patients with chronic LBP (23 male, 50 female; mean age 71 years) treated with tramadol-acetaminophen (n = 36) and celecoxib (n = 37) was performed. All patients were assessed using the self-reported questionnaires. A mediation model was constructed using a bootstrapping method to evaluate the mediating effects of pain relief after treatment. Results. A total of 35 (55.6%) patients met the criteria for apathy. A four-week treatment regimen in the tramadol group conferred significant improvements in the Apathy scale and numerical rating scale but not in the Rolland-Morris Disability Questionnaire, Pain Disability Assessment Scale, or Pain Catastrophizing Scale. The depression component of the Hospital Anxiety and Depression Scale was lower in the tramadol group than in the celecoxib group. The mediation analysis found that the impact of tramadol-acetaminophen on the change in apathy was not mediated by the pain relief. Conclusions. Tramadol-acetaminophen was effective at reducing chronic LBP and conferred a prophylactic motivational effect in patients with chronic LBP.

OBJECTIVE: To assess the routine use of barium swallow study in patients with chronic cough. METHODS: Between October of 2011 and March of 2012, 95 consecutive patients submitted to chest X-ray due to chronic cough (duration > 8 weeks) were included in the study. For study purposes, additional images were obtained immediately after the oral administration of 5 mL of a 5% barium sulfate suspension. Two radiologists systematically evaluated all of the images in order to identify any pathological changes. Fisher's exact test and the chi-square test for categorical data were used in the comparisons. RESULTS: The images taken immediately after barium swallow revealed significant pathological conditions that were potentially related to chronic cough in 12 (12.6%) of the 95 patients. These conditions, which included diaphragmatic hiatal hernia, esophageal neoplasm, achalasia, esophageal diverticulum, and abnormal esophageal dilatation, were not detected on the images taken without contrast. After appropriate treatment, the symptoms disappeared in 11 (91.6%) of the patients, whereas the treatment was ineffective in 1 (8.4%). We observed no complications related to barium swallow, such as contrast aspiration. CONCLUSIONS: Barium swallow improved the detection of significant radiographic findings related to chronic cough in 11.5% of patients. These initial findings suggest that the routine use of barium swallow can significantly increase the sensitivity of chest X-rays in the detection of chronic cough-related etiologies. PMID:24473762
Background Chronic illnesses are diseases of long duration and generally of slow progression. They cause significant quality of life impairment. The aim of this study was to analyse psychosocial predictors of quality of life and of subjective well-being in chronic Portuguese patients. Methods Chronic disease patients (n = 774) were recruited from central Portuguese Hospitals. Participants completed self-reported questionnaires assessing socio-demographic, clinical, psychosocial and outcome variables: quality of life (HRQL) and subjective well-being (SWB). MANCOVA analyses were used to test psychosocial factors as determinants of HRQL and SWB. Results After controlling for socio-demographic and clinical variables, results showed that dispositional optimism, positive affect, spirituality, social support and treatment adherence are significant predictors of HRQL and SWB. Similar predictors of quality of life, such as positive affect, treatment adherence and spirituality, were found for subgroups of disease classified by medical condition. Conclusions The work identifies psychosocial factors associated with quality of life. The predictors for the entire group of different chronic diseases are similar to the ones found in different chronic disease subgroups: positive affect, social support, treatment adherence and spirituality. Patients with more positive affect, additional social support, an adequate treatment adherence and a feel-good spirituality, felt better with the disease conditions and consequently had a better quality of life. This study contributes to understanding and improving the processes associated with quality of life, which is relevant for health care providers and chronic diseases support. PMID:24405802

In spite of various investigations devoted to a problem of chronic bronchitis, many problems concerning both the reasons of the origin of this disease, and the essence of the processes, explicating in the bronchial tubes, especially on early stages of the disease, remain insufficiently studied. It makes it difficult to use an integrated approach to chronic bronchitis, that would reflect the peculiarities of its etiology, pathogenesis, its clinical course and efficiency of the therapy. During the last years the data of the clinical laboratory analysis of chronic bronchitis in connection with its immune therapy have been accumulated. In the literature there is a lot of information about the violation of immune reactions in the organism of patients, methods of the immune therapy, the data of the successful application of the intravenous laser therapy in the treatment of obstructive chronic bronchitis and bronchial asthma. However, there is no research explaining the mechanisms of the laser radiation impact on the immune status of patients suffering from chronic bronchitis. According to this it has become extremely urgent to research the mechanisms of the laser radiation impact on immune competent cells of patients suffering from chronic bronchitis.

To identify serum cytokine networks specific to chronic inflammatory demyelinating polyneuropathy (CIDP), serum samples of two subgroups (18 patients with typical CIDP and 12 patients with multifocal acquired demyelinating sensory and motor neuropathy [MADSAM]) were analyzed with multiplex magnetic bead-based cytokine assay. TNF-α, HGF, MIP-1β and IL-1β levels were significantly higher in total CIDP patients than in normal controls. Of these, HGF levels were elevated in typical CIDP patients, but not in MADSAM patients. Patients with high HGF levels showed good responses to steroid treatment. Different cytokine profiles among the CIDP subtypes presumably reflect differences in pathophysiology.

The main objective of this study was to compare the reporting of health status and symptom severity, for a set of core symptoms related to imatinib therapy, between chronic myeloid leukemia patients and their treating physicians. Patients were asked to complete a questionnaire including questions on symptom severity and health status. The symptoms assessed were: abdominal discomfort, diarrhea, edema, fatigue, headache, muscle cramps, musculoskeletal pain, nausea and skin problems. The physicians were asked to complete a questionnaire for each of their patients entering the study. Four hundred twenty-two patients were included in the study. All respective paired physicians (n=29) completed the questionnaire, and thus the analyses are based on 422 patient-physician dyads. Agreement on symptom ratings ranged from 34% (for muscle cramps) to 66% (for nausea). For all symptoms, patients reported higher severity more often than their physicians. The three symptoms whose severity was most frequently underestimated by physicians were fatigue (51%), muscle cramps (49%) and musculoskeletal pain (42%). Health status was overestimated by physicians in 67% of the cases. Physicians and their patients with chronic myeloid leukemia often disagree in their ratings of the patients’ symptom severity. Most typically, physicians tend to underestimate symptom severity and overestimate the overall health status of their patients. Current findings support the use of patient-reported outcome measures as a possible means to enhance the management of patients with chronic myeloid leukemia. PMID:24241488

Patients with chronic kidney disease (CKD) experience co-morbid illneses including cardiovascular disease (CVD) and retinopathy. The purpose of this study was to assess the association between retinopathy and self reported CVD in a subgroup of the participants of the Chronic Renal Insufficiency Cohort (CRIC) study. In this observational, ancillary investigation, 2605 CRIC participants were invited to participate in this study, and non-mydriatic fundus photographs in both eyes were obtained in 1936 subjects. Photographs were reviewed in a masked fashion at a central photograph reading center. Presence and severity of retinopathy (diabetic, hypertensive or other) and vessel diameter caliber were assessed using standard protocols by trained graders masked to information about study participants. History of self-reported cardiovascular disease was obtained using a medical history questionnaire. Kidney function measurements, traditional and non-traditional risk factors for CVD were obtained from the CRIC study. Greater severity of retinopathy was associated with higher prevalence of any cardiovascular disease and this association persisted after adjustment for traditional risk factors for CVD. Presence of vascular abnormalities usually associated with hypertension was also associated with increased prevalence of CVD. We found a direct relationship between CVD prevalence and mean venular caliber. In conclusion, presence of retinopathy was associated with CVD, suggesting that retinovascular pathology may be indicative of macrovascular disease even after adjustment for renal dysfunction and traditional CVD risk factors. This would make assessment of retinal morphology a valuable tool in chronic kidney disease studies of CVD outcomes. PMID:22516527

Registration of luminol-dependent chemoluminescence of blood cells and iron-induced chemoluminescence of the serum was used to study generation of active oxygen forms and lipid peroxidation in patients with chronic bronchitis (CB). 49 patients with lingering CB showed inhibition of blood cell function and enhancement of lipid peroxidation. The addition of halotherapy to combined treatment of these patients promoted correction of the disorders and improvement of CB course.

Three self-report questionnaires (the Beck Depression Inventory, the MMPI-D scale, and the depression subscale of the Middlesex Hospital Questionnaire) were examined to see how accurately they could identify chronic low back pain patients who were suffering depression, as defined by DSM-III criteria. According to these criteria, 25% of a sample of 68 patients currently were depressed, a rate comparable to those reported by other studies that have used standardized criteria. On the basis of relative conditional probability ratios, the BDI was shown to be the most efficient instrument for identifying these cases and represents an excellent screening device for depression with this population. The individual items of the BDI then were examined, and the conditional probability ratios revealed that several may be helpful as indicators of possible depression among chronic low back pain patients. The relationship between depression and chronic pain is reconsidered in the light of these results.
Hyperphosphataemia is a frequent complication in patients with chronic kidney disease and is associated with increased cardiovascular morbidity. Lanthanum carbonate is a calcium-free phosphate binder indicated in patients with chronic kidney disease. Its digestive absorption is minimal (<0,002%). This minimal quantity is rapidly excreted by the hepatobiliary system, but there is an initial accumulation in liver and bone, which reaches a plateau within a few weeks. Long-term follow-up until six years did not show any bone or liver toxicity. Efficacy and safety of lanthanum carbonate have been assessed in randomized trials. The most common side effects reported were gastrointestinal and occurred with a similar incidence than with placebo and other phosphate binders. Hypercalcemia was less frequent than with calcium carbonate. This review highlights pharmacokinetic, pharmacodynamic and clinical (efficacy and safety) properties of lanthanum carbonate and discusses its place in the management of hyperphosphataemia in patients with chronic kidney disease.

Previous studies indicate that first-episode and chronic schizophrenic patients do not differ regarding neuropsychological performance as assessed with standard cognitive tasks. For the present study, it was investigated whether first-episode and chronic schizophrenics report similar subjective cognitive deficits. The Frankfurt Complaint Questionnaire (FCQ), a scale devised for assessing subjective cognitive disturbances in schizophrenia, was administered to 20 first-episode and 36 chronic schizophrenic patients, as well as 20 healthy controls. The schizophrenic subsamples did not differ on any of the FCQ subscales or on a "lie scale," measuring illness denial. Psychopathological ratings were comparable for both groups. As expected, healthy subjects reported significantly less cognitive and perceptual problems than schizophrenic patients. In marked contrast to a Kraepelinian view of schizophrenia, the present data confirm previous studies conducted with objective neuropsychological tests that schizophrenia is a neurodevelopmental rather than a neurodegenerative disorder.

The intraocular pressures of a total of 286 eyes of patients with lepromatous and borderline lepromatous leprosy who never had regular ophthalmological care or local eye treatment were measured. The patients were categorised according to the type of leprosy they had, and the eyes were categorised as without or with chronic plastic iridocyclitis. In patients with lepromatous and borderline lepromatous types of leprosy the intraocular pressure was significantly lower in eyes with chronic plastic iridocylitis 10.1 (3.6) mmHg than in both unaffected eyes 11.0 (3.2) mmHg and control eyes 13.5 (2.5) mmHg. It has been shown that chronic plastic iridocyclitis which remains untreated for years results in a lower intraocular pressure than normal.

Naltrexone is effective in treating opioid dependence by blocking µ, κ and δ opiate receptors. Naltrexone is mainly metabolized to an active metabolite 6β-naltrexol by dihydrodiol dehydrogenase enzymes. Concomitant opioids will not be effective while patients are taking this antagonist. This was a retrospective analysis of urinary excretion data collected from patients being treated with pain between November 2011 and May 2012. Naltrexone, 6β-naltrexol and concomitant opiate concentrations were measured by liquid chromatography-tandem mass spectrometry. Interpatient variability was calculated from first-visit specimens, and intrapatient variability was calculated from patients with two or more visits. Relationships of the metabolic ratio (MR; 6β-naltrexol/naltrexone) with age, gender and urinary pH were also explored. From 88 first-visit patient specimens, the median MR was 3.28 (range 0.73-17.42). The MR was higher in women than men (5.00 vs. 3.14, P< 0.05). The MR showed no association based on age and urinary pH. Eighteen of 88 patients taking oral naltrexone tested positive for concomitant opiate use. Urinary MRs of 6β-naltrexol/naltrexone were highly variable, which may contribute to variability in efficacy, toxicity and patient willingness to take naltrexone as directed. Twenty percent of patients tested positive for opiates and naltrexone, thus showing the importance of monitoring patients taking naltrexone.

Background Proteasome inhibitors are anticancer compounds that disrupt the proteolytic activity of the proteasome and lead to tumor cell growth arrest and apoptosis. Bortezomib is a proteasome inhibitor that is currently approved for use in multiple myeloma and mantle cell lymphoma. It induces apoptosis of chronic myeloid leukemia (CML) cells in vitro, but the activity of bortezomib in patients with imatinib-resistant CML is unknown. Methods We conducted a pilot trial to evaluate the activity of single agent bortezomib in CML. Seven patients with imatinib-refractory CML were treated with bortezomib at a dose of 1.5 mg/m2 on days 1, 4, 8 and 11 every 3 weeks. Results The median number of cycles received was 2. No patient had a hematologic or cytogenetic response. Three patients had a temporary decrease in basophil counts associated with therapy with bortezomib. Six patients developed grade 3-4 nonhematological toxicities. Conclusion Bortezomib had minimal efficacy and considerable toxicity in patients with imatinib-refractory CML. Further studies should focus on alternative approaches to employ proteasome inhibitors in the treatment of CML, such as in combination with tyrosine kinase inhibitors or as a strategy to eradicate leukemic stem cells.

The aim of this study was to describe specific histological findings of the Coxiella burnetii-infected aneurysmal abdominal aortic wall. Tissue samples of the aneurysmal abdominal aortic wall from seven patients with chronic Q fever and 15 patients without evidence of Q fever infection were analysed and compared. Chronic Q fever was diagnosed using serology and tissue PCR analysis. Histological sections were stained using haematoxylin and eosin staining, Elastica van Gieson staining and immunohistochemical staining for macrophages (CD68), T lymphocytes (CD3), T lymphocyte subsets (CD4 and CD8) and B lymphocytes (CD20). Samples were scored by one pathologist, blinded for Q fever status, using a standard score form. Seven tissue samples from patients with chronic Q fever and 15 tissue samples from patients without Q fever were collected. Four of seven chronic Q fever samples showed a necrotizing granulomatous response of the vascular wall, which was characterized by necrotic core of the arteriosclerotic plaque (P = 0.005) and a presence of high numbers of macrophages in the adventitia (P = 0.007) distributed in typical palisading formation (P = 0.005) and surrounded by the presence of high numbers of T lymphocytes located diffusely in media and adventitia. Necrotizing granulomas are a histological finding in the C. burnetii-infected aneurysmal abdominal aortic wall. Chronic Q fever should be included in the list of infectious diseases with necrotizing granulomatous response, such as tuberculosis, cat scratch disease and syphilis. PMID:24953727

Pain has been reported to be a common problem in the general population and end-stage renal disease (ESRD) patients. Although similar data for pre-ESRD patients are lacking, we recently reported that the prevalence of pain is also very high (>70%) among pre-ESRD patients at a Los Angeles County tertiary referral centre. The high prevalence of pain in the CKD population is particularly concerning because pain has been shown to be associated with poor quality of life. Of greater concern, poor quality of life, at least in dialysis patients, has been shown to be associated with poor survival. We herein discuss the pathophysiology of common pain conditions, review a commonly accepted approach to the management of pain in the general population, and discuss analgesic-induced renal complications and therapeutic issues specific for patients with reduced renal function.

In a retrospective study from the Dutch Mononitrate Quality of Life (DUMQOL) Study Group, the authors found that patients with angina with concomitant diabetes or hypercholesterolemia derived more benefit from changing over to a once-daily nitrate treatment regimen than did patients without angina. The aim of this study was to assess this issue prospectively. In an open-label study, patients with stable angina pectoris from facilities in Germany, Portugal, and me Czech Republic were treated for 3 months with multiple daily doses and subsequently for 3 more months with once-daily isosorbide mononitrate/dinitrate. After the first and second 3-month periods, they were assessed by a validated QOL battery including domains for mobility, side effects, life satisfaction, anginal pain, and psychological distress. In the 1045 patients who participated in the study, the mean summary domain scores varied from 5 to 16 points and score improvements from 1.6 to 4.3 points. In the patients without concomitant hypertension and smokers, domain scores improved less than they did in the patients without, with differences in domain score improvements up to 1.0 points (P<0.001), which is substantial considering the range of improvement was between 1.6 and 4.3 points. In the patients with diabetes mellitus or hypercholesterolemia, a reverse pattern was observed with differences in domain score improvements up to 0.4 points (P<0.05). Patients with angina with diabetes or hypercholesterolemia derived more benefit from an asymmetric regimen of isosorbide mononitrate/dinitrate than did patients without. Patients with angina with hypertension and smokers benefited less. Differences in endothelial function may be involved.

Esophageal atresia (EA) is defined as a discontinuity of the lumen of the esophagus repaired soon after birth. Dysphagia is a common symptom in these patients, usually related to stricture, dysmotility or peptic esophagitis. We present 4 cases of patients with EA who complained of dysphagia and the diagnosis of Eosinophilic esophagitis (EoE) was made, ages ranging from 9 to 16 years. Although our patients were on acid suppression years after their EA repair, they presented with acute worsening of dysphagia. Esophogastroduodenoscopy and/or barium swallow did not show stricture and biopsies revealed elevated eosinophil counts consistent with EoE. Two of 4 patients improved symptomatically with the topical steroids. It is important to note that all our patients have asthma and 3 out of 4 have tested positive for food allergies. One of our patients developed recurrent anastomotic strictures that improved with the treatment of the EoE. A previous case report linked the recurrence of esophageal strictures in patients with EA repair with EoE. Once the EoE was treated the strictures resolved. On the other hand, based on our observation, EoE could be present in patients without recurrent anastomotic strictures. There appears to be a spectrum in the disease process. We are suggesting that EoE is a frequent concomitant problem in patients with history of congenital esophageal deformities, and for this reason any of these patients with refractory reflux symptoms or dysphagia (with or without anastomotic stricture) may benefit from an endoscopic evaluation with biopsies to rule out EoE.

Background Risk factors may influence the improvement or worsening of erectile dysfunction (ED). The aim of the current study was to evaluate the effect of systemic hypertension on ED in patients with peripheral arterial disease. Methods The effect of hypertension on ED was assessed in 125 consecutive patients in a cross-sectional quantitative study. The ages of the patients ranged from 19 to 88 years old (mean: 59.82 ± 10.48 years). The only exclusion criterion was the amputation of one or both legs. The ankle-arm index was assessed and the international index of ED questionnaire was applied to all participants in the study. Results Of the 125 patients, 22 (17.6%) had mild (grade 1), 50 (40.0%) had moderate (grade 2) and 53 (42.4%) had severe (grade 3) ED. Hypertensive patients have more ED, with ED in hypertensive patients being associated to chronic arterial disease. However, in comparison with normotensive patients, hypertension exerts an immediate protective effect on erectile function. Conclusions In conclusion, although erectile function is initially protected by systemic arterial hypertension in patients with chronic arterial disease, both chronic arterial disease and ED deteriorate over the long term in hypertensive patients.

Monoclonal antimyosin antibody studies were undertaken to assess the presence of myocardial uptake in patients with chronic idiopathic dilated cardiomyopathy. Three groups were studied: 17 patients with chronic (greater than 12 months) idiopathic dilated cardiomyopathy, 12 patients with a large, poorly contracting left ventricle not due to dilated cardiomyopathy (control patients) and 8 normal individuals. The patients in the cardiomyopathy and control groups showed a similar degree of clinical and functional impairment. Imaging was undertaken 48 h after antimyosin injection. The heart/lung ratio of antimyosin uptake was used to assess the results. The mean ratio in the cardiomyopathy group was 1.83 +/- 0.36 (range 1.40 to 2.80), a value significantly higher than that obtained in the control patients without cardiomyopathy (mean 1.46 +/- 0.04, range 1.38 to 1.50) or normal subjects (mean 1.46 +/- 0.13, range 1.31 to 1.6) (p less than 0.01). No difference in the ratio was noted between the normal subjects and control patients. Abnormal antimyosin uptake was seen in 12 (70%) of the 17 patients with cardiomyopathy and in only 1 (8%) of the 12 control patients. Positive monoclonal antimyosin antibody studies are highly prevalent in chronic idiopathic dilated cardiomyopathy.
