Porphyrias are a group of metabolic diseases that affect the skin and/or nervous system. In 2008, three unrelated patients were diagnosed with variegate porphyria at the CIPYP (Centro de Investigaciones sobre Porfirinas y Porfirias). Sequencing of the protoporphyrinogen oxidase gene, the gene altered in this type of porphyria, revealed three previously undescribed mutations: c.338+3insT, c.807G>A, and c.808-1G>C. As these mutations do not affect the protein sequence, we hypothesized that they might be splicing mutations. RT-PCRs performed on the patient's mRNAs showed normal mRNA or no amplification at all. This result indicated that the aberrant spliced transcript is possibly being degraded. In order to establish whether they were responsible or not for the patient's disease by causing aberrant splicing, we utilized a minigene approach. We found that the three mutations lead to exon skipping; therefore, the abnormal mRNAs are most likely degraded by a mechanism such as nonsense-mediated decay. In conclusion, these mutations are responsible for the disease because they alter the normal splicing pathway, thus providing a functional explanation for the appearance of disease and highlighting the use of minigene assays to complement transcript analysis.
Full Text Available Abstract Variegate porphyria (VP is an autosomal dominantly inherited hepatic porphyria. The genetic defect in the PPOX gene leads to a partial defect of protoporphyrinogen oxidase, the penultimate enzyme of heme biosynthesis. Affected individuals can develop cutaneous symptoms in sun-exposed areas of the skin and/or neuropsychiatric acute attacks. The identification of the genetic defect in VP families is of crucial importance to detect the carrier status which allows counseling to prevent potentially life threatening neurovisceral attacks, usually triggered by factors such as certain drugs, alcohol or fasting. In a total of 31 Swedish VP families sequence analysis had identified a genetic defect in 26. In the remaining five families an extended genetic investigation was necessary. After the development of a synthetic probe set, MLPA analysis to screen for single exon deletions/duplications was performed. We describe here, for the first time, two partial deletions within the PPOX gene detected by MLPA analysis. One deletion affects exon 5 and 6 (c.339-197_616+320del1099 and has been identified in four families, most probably after a founder effect. The other extends from exon 5 to exon 9 (c.339-350_987+229del2609 and was found in one family. We show that both deletions are mediated by Alu repeats. Our findings emphasize the usefulness of MLPA analysis as a complement to PPOX gene sequencing analysis for comprehensive genetic diagnostics in patients with VP.

Variegate porphyria is an autosomal dominant disorder that usually presents with photosensitivity and acute neurological crises in adulthood. It is caused by heterozygous mutations in the protoporphyrinogen oxidase gene (PPOX). A rarer variant, homozygous variegate porphyria (HVP), presents in childhood with recurrent skin blisters and scarring. More variable features of HVP are short stature, brachydactyly, nystagmus, epilepsy, developmental delay and mental retardation. We describe a child who presented with nystagmus, developmental delay and ataxia, combined with a photosensitive eruption. Analysis of porphyrins in plasma, urine and stool supported a clinical diagnosis of HVP. DNA from the patient showed that he is compound heterozygous for two novel missense mutations in the PPOX coding region: c.169G>C (p.Gly57Arg) and c.1259C>G (Pro420Arg). Interestingly, cranial magnetic resonance imaging showed an absence of myelin, a feature not previously reported in HVP, which expands the differential diagnosis of childhood hypomyelinating leucoencephalopathies. © 2013 British Association of Dermatologists.

Administration of oxadiazon or oxyfluorfen (1000 ppm in the diet) to male BALB/c mice for 9 days resulted in experimental porphyria, resembling the acute phase of human variegate porphyria. Urinary concentrations of 5-aminolevulinic acid and porphobilinogen reached 1500 and 3000 mumol/L, respectively. Both herbicides caused a decrease of protoporphyrinogen oxidase activity in liver and kidney. Brain protoporphyrinogen oxidase activity was not altered. Liver and kidney porphyrin content increased to 11 and 17 nmol/g, respectively (control mice, 2 nmol/g). Over 50% of liver and kidney porphyrins were in the reduced (porphyrinogen) form. Bile of oxadiazon-treated mice contained 700 nmol/mL of protoporphyrinogen (control mice, 15 nmol/mL). Porphyrin content of the trigeminal nerve increased from 1 nmol/g in control animals to 11 nmol/g in oxadiazon-treated animals, suggesting a possible contribution of peripheral nerve porphyrins to porphyric neuropathy. Mice treated with 125 ppm of oxadiazon in the diet for 9 days excreted moderately elevated levels of porphobilinogen in urine (control mice, less than 50 mumol/L; treated mice, 330 mumol/L). Administration of phenobarbital or phenytoin (single injections on days 7, 8, and 9) increased the urinary porphobilinogen concentration to 3500 mumol/L. This response to porphyrogenic drugs resembles the response observed in human acute porphyrias.

To determine characteristics, clinical features and triggers of acute porphyria in hospitalized patients presenting to a tertiary care center in Pakistan. Case records of 26 patients hospitalized with diagnosis were identified through computerized hospital patients data. The diagnosis of acute porphyria was based on pertinent clinical features and laboratory investigations after exclusion of other alternative diagnosis and patients previously diagnosed as porphyric. The data was analyzed through SPSS software version 11.0. Twelve patients (46.2%) were males. Mean age was 21 years. Most common manifestation were gastrointestinal (n=22; 88.5%) followed by neurological symptoms (n=14; 54%). Neurological manifestations included seizures (n=9; 34.6%) and neuropathy (n=6; 23%). One patient presented with depression and insomnia. Family history was positive in (n=8; 30.8%). Eighteen (69%) had history of previous attacks at their presentation to the hospital. Most common precipitating factor was eating outside (n=18; 69%). Porphyrias are uncommon and cryptic group of diseases. This study shows a slightly different gender distribution, earlier onset of symptoms, higher number of neuropsychiatric symptoms (especially seizures), more distal neuropathies and different precipitant in the studied subset of patients than described previously in the western studies.

Full Text Available Acute intermittent porphyria is a rare metabolic disorder resulting from a partial deficiency of porphobilinogen deaminase, enzyme in the heme biosynthetic pathway. Its inheritance is autosomal dominant. A deficiency of porphobilinogen deaminase is not sufficient by its self to produce acute intermittent porphyria, and other activating factors must also be present. These include some drugs, hormones, infection, injury and alcohol. Besides others, anesthetics have been implicated in the triggering of a number of severe porphyric reactions. Although there is no clinical evidence, the fear of hypothesized porphyrinogenicity of repetitive anesthetics exposures still remains. Despite these doubts, we report here the case of uneventful repeated exposure to anesthetics in a patient suffering from acute intermittent porphyria, within a fifteen- month period. On both occasions, the patient was safely exposed to certain anesthetics included: propofol, sevoflurane, rocuronium, midazolam and fentanyl.

Porphyria cutanea tarda is the most common form of porphyria, characterized by the decreased activity of the uroporphyrinogen decarboxylase enzyme. Several reports associated HFE gene mutations of hereditary hemochromatosis with porphyria cutanea tarda worldwide, although up to date only one study has been conducted in Brazil. Investigation of porphyria cutanea tarda association with C282Y and H63D mutations in the HFE gene. Identification of precipitating factors (hepatitis C, HIV, alcoholism and estrogen) and their link with HFE mutations. An ambispective study of 60 patients with PCT was conducted during the period from 2003 to 2012. Serological tests for hepatitis C and HIV were performed and histories of alcohol abuse and estrogen intake were investigated. HFE mutations were identified with real-time PCR. Porphyria cutanea tarda predominated in males and alcohol abuse was the main precipitating factor. Estrogen intake was the sole precipitating factor present in 25% of female patients. Hepatitis C was present in 41.7%. All HIV-positive patients (15.3%) had a history of alcohol abuse. Allele frequency for HFE mutations, i.e., C282Y (p = 0.0001) and H63D (p = 0.0004), were significantly higher in porphyria cutanea tarda patients, compared to control group. HFE mutations had no association with the other precipitating factors. Alcohol abuse, hepatitis C and estrogen intake are prevalent precipitating factors in our porphyria cutanea tarda population; however, hemochromatosis in itself can also contribute to the outbreak of porphyria cutanea tarda, which makes the research for HFE mutations necessary in these patients.

Although the biosynthetic pathway to heme has been well elucidated and errors along that route have been identified and firmly connected to specific diseases, the porphyrias, slight but nonspecific abnormalities, are occasionally invoked as proof of porphyria or in support of other diagnoses. An errant patient with a conundrum of symptoms but without an explanation for them might have to take iatrogenic detours only to learn after what are at times ulyssean vagaries that the initial diagnosis of porphyria is in the end untenable. Thus the porphyrias are superb examples of the interface between laboratory and clinical medicine, in which the occurrence of the Ulysses syndrome can be curtailed through the careful ordering of tests and cogent interpretation of their results.
Full Text Available Facing a patient with acute intermittent porphyria (AIP, there is narrow safety margin which circumscribe all the therapeutic actions including choice of drugs. This would become even more complicated when it comes to a stressful and drug-dependent process like a cardiopulmonary bypass. According to author′s researches, no specific AIP case of tricuspid valve (TV replacement is reported recently. Furthermore, fast-track anesthesia was safely used in this 37-year-old male known the case of AIP, who was a candidate for TV replacement and removing the port catheter. The patient was extubated subsequently, only 3 h after entering the Intensive Care Unit.
Full Text Available Heme, like chlorophyll, is a primordial molecule and is one of the fundamental pigments of life. Disorders of normal heme synthesis may cause human diseases, including certain anemias (X-linked sideroblastic anemias and porphyrias. Porphyrias are classified as hepatic and erythropoietic porphyrias based on the organ system in which heme precursors (5-aminolevulinic acid (ALA, porphobilinogen and porphyrins are chiefly overproduced. The hepatic porphyrias are further subdivided into acute porphyrias and chronic hepatic porphyrias. The acute porphyrias include acute intermittent, hereditary copro-, variegate and ALA dehydratase deficiency porphyria. Chronic hepatic porphyrias include porphyria cutanea tarda and hepatoerythropoietic porphyria. The erythropoietic porphyrias include congenital erythropoietic porphyria (Gűnther’s disease and erythropoietic protoporphyria. In this review, we summarize the key features of normal heme synthesis and its differing regulation in liver versus bone marrow. In both organs, principal regulation is exerted at the level of the first and rate-controlling enzyme, but by different molecules (heme in the liver and iron in the bone marrow. We also describe salient clinical, laboratory and genetic features of the eight types of porphyria.

Acute intermittent porphyria (AIP) is a rare metabolic disorder due to a deficiency of porphobilinogen deaminase, the third enzyme of the heme biosynthetic pathway. This low enzymatic activity may predispose to the appearance of acute neurological attacks. Seminal studies suggested that AIP was associated with changes in tryptophan homeostasis with inconclusive results. Therefore, the aim of this study was to analyze the urinary metabolome of AIP patients focusing on tryptophan metabolism using state-of-the-art technology. This was a case-control study including a group of 25 AIP patients with active biochemical disease and increased excretion of heme-precursors and 25 healthy controls. Tryptophan and related compounds and metabolites including: large neutral amino acids (LNAAs), serotonin, kynurenine, kynurenic acid and anthranilic acid were quantified in urine by liquid chromatography tandem-mass spectrometry (LC-MS/MS). Twenty-nine biological markers (including metabolic ratios and absolute concentrations) were compared between patients and controls. Significant differences were found in the tryptophan-kynurenine metabolic pathway. Compared to controls, AIP patients showed: (a) increased urinary excretion of kynurenine and anthranilic acid (Pmetabolome of hepatic porphyrias. Copyright © 2017. Published by Elsevier B.V.

Recent descriptions of the clinical and laboratory features of subjects with acute porphyrias in the US are lacking. Our aim was to describe clinical, biochemical, and genetic features of 108 subjects. Between September 2010 and December 2012, 108 subjects with acute porphyrias (90 acute intermittent porphyrias, 9 hereditary coproporphyrias, 9 variegate porphyrias) were enrolled into an observational study. Genetic testing was performed at a central genetic testing laboratory and clinical information entered into a central database. Selected features were compared with data for adults in the US. Most subjects (88/108, 81%) were female, with self-reported onset of symptoms in the second through fourth decades of life. The most common symptom was abdominal pain. Appendectomies and cholecystectomies were common before a diagnosis of porphyria. The diagnosis was delayed by a mean of 15 years. Anxiety and depression were common, and 18% complained of chronic symptoms, especially neuropathic and other pains. The incidences of systemic arterial hypertension, chronic kidney disease, seizure disorders, and psychiatric conditions were markedly increased. Mutations of the known causative genes were found in 102/105 of those tested, with novel mutations being found in 37, including in 7/8 subjects with hereditary coproporphyria. Therapy with intravenous hematin was the most effective therapy both for treatment of acute attacks and for prevention of recurrent attacks. Acute porphyrias often remain undiagnosed for more than a decade after first symptoms develop. Intravenous hematin is the treatment of choice, both for treatment of acute attacks and for prevention of recurrent attacks. Copyright © 2014 Elsevier Inc. All rights reserved.

The authors study a case of acute porphyria in a young woman who was taking oral contraceptives and who began having abdominal pain and bilateral radial paralysis with neuropsychic disorders. The quantitative and chromatographic analyses of urine, feces, and liver porphyrins revealed a pattern of excretion compatible but not definite of porphyria variegata, making this an example of porphyria of difficult noslogic placement. The problems of classification, the action of the contraceptive drugs as probable triggering agents (of the clinical picture) by means of their action on the ALA-synthetase, the rare form of neuropathy, and the rarity of these types of porphyrias in our country are analyzed and discussed. The patient did not present the endocrine-metabolic disorders that are commonly evidenced in these cases.

Porphyrias are rare genetic metabolic disorders, which result from deficiencies of enzymes in the heme biosynthesis pathway. Depending on the enzyme defect, different types of porphyrins and heme precursors accumulate for the different porphyria diseases in erythrocytes, liver, blood plasma, urine and stool. Patients with acute hepatic porphyrias can suffer from acute neuropathic attacks, which can lead to death when undiagnosed, but show only unspecific clinical symptoms such as abdominal pain. Therefore, in addition to chromatographic methods, a rapid screening test is required to allow for immediate identification and treatment of these patients. In this study, fluorescence spectroscopic measurements were conducted on blood plasma and phantom material, mimicking the composition of blood plasma of porphyria patients. Hydrochloric acid was used to differentiate the occurring porphyrins (uroporphyrin-III and coproporphyrin-III) spectroscopically despite their initially overlapping excitation spectra. Plasma phantom mixtures were measured using dual wavelength excitation and the corresponding concentrations of uroporphyrin-III and coproporphyrin-III were determined. Additionally, three plasma samples of porphyria patients were examined and traces of coproporphyrin-III and uroporphyrin-III were identified. This study may therefore help to establish a rapid screening test method with spectroscopic differentiation of the occurring porphyrins, which consequently allows for the distinction of different porphyrias. This may be a valuable tool for clinical porphyria diagnosis and rapid or immediate treatment.

Background & Aims Porphyria cutanea tarda (PCT) is an iron-related disorder caused by reduced activity of hepatic uroporphyrinogen decarboxylase (UROD); it can be treated by phlebotomy or low doses of hydroxychloroquine. We performed a prospective pilot study to compare the efficacy and safety of these therapies. Methods We analyzed data from 48 consecutive patients with well-documented PCT to characterize susceptibility factors; patients were treated with phlebotomy (450 mL, every 2 weeks until they had serum ferritin levels of 20 ng/mL) or low-dose hydroxychloroquine (100 mg orally, twice weekly, until at least 1 month after they had normal plasma levels of porphyrin). We compared the time required to achieve a normal plasma porphyrin concentration (remission, the primary outcome) for 17 patients treated with phlebotomy and 13 treated with hydroxychloroquine. Results The time to remission was a median 6.9 months for patients that received phlebotomy and 6.1 months for patients treated with hydroxychloroquine treatment (6.7 and 6.5 months for randomized patients), a difference that was not significant (Log Rank P=.06 and P=.95, respectively). The sample size was insufficient to confirm noninferiority of hydroxychloroquine treatment (hazard ratio [HR], 2.19; 95% confidence interval [CI], 0.95–5.06) for all patients. Patients that received hydroxychloroquine had substantially better compliance. There were no significant side effects of either treatment. Conclusions Hydroxychloroquine, 100 mg twice weekly, is as effective and safe as phlebotomy in patients with PCT, although noninferiority was not established. Given these results, higher-dose regimens of hydroxychloroquine, which have more side effects, do not seem justified. Compliance was better and projected costs were lower for hydroxychloroquine than phlebotomy treatment. Long-term studies are needed to compare durability of response. PMID:22985607

Full Text Available Porphyria cutanea tarda (PCT is a rare disease, with a strong association with hepatitis C virus. PCT is particularly problematic in end-stage renal disease patients as they have no renal excretion of porphyrins and these are poorly dialyzed. Also, conventional treatment of PCT is compromised in these patients as hydroxychloroquine is contraindicated, phlebotomies with the stipulated frequency are poorly tolerated in already anaemia-prone patients, and iron-chelating agents are less efficient in removing iron and contribute to worsening anaemia. The authors report a patient on haemodialysis, with hepatitis C infection, that is diagnosed with PCT. Despite the good clinical results with deferoxamine, she became dependent on blood transfusions because of her ferropenic state. Every time oxide iron was started, the patient developed clinical features of the disease, resolving after the suspension of the drug. A decision was made to start the patient on ferric carboxymaltose, which was well tolerated without disease symptoms and need of further blood transfusions. This case suggests that deferoxamine is efficient in treatment of porphyria cutanea tarda. Also, ferric carboxymaltose may be a valuable option for refractory anaemia in patients with this disease and end-stage renal disease, as it seems to provide iron without clinical relapse of the disease.

Porphyria cutanea tarda (PCT), the most common porphyria disease, is characterized by blistering and skin fragility of sun-exposed skin. The symptoms are caused by lowered activity of uroporphyrinogen decarboxylase (URO-D) resulting in accumulation of water-soluble porphyrins in the skin. Most PCT...... cases are sporadic but can be familiar due to mutations in the URO-D gene located on chromosome number 1. The disease may be exacerbated by environmental factors. Iron accumulation is a characteristic finding and there is an association to hereditary haemochromatosis. Therapeutic venesection reduces...... the iron load and the uroporphyrins are mobilized by treatment with hydroxychloroquine. An increased risk of liver cirrhosis and hepatocellular carcinoma may presumably be reduced by early diagnosis and treatment. Udgivelsesdato: 2000-Apr-3...

Porphyrias are a group of metabolic diseases that arise from deficiencies in the heme biosynthetic pathway. A partial deficiency in hydroxymethylbilane synthase (HMBS) produces a hepatic disorder named Acute Intermittent Porphyria (AIP); the acute porphyria is more frequent in Argentina. In this paper we review the results obtained for 101 Argentinean AIP families and 6 AIP families from foreign neighbour countries studied at molecular level at Centro de Investigaciones sobre Porfirinas y Porfirias (CIPYP). Thirty-five different mutations were found, of which 14 were described for the first time in our population. The most prevalent type of mutations was the missense mutations (43%) followed by splice defects (26%) and small deletions (20%). An odd case of a double heterozygous presentation of AIP in a foreign family from Paraguay is discussed. Moreover, it can be noted that 38 new families were found carrying the most frequent mutation in Argentina (p.G111R), increasing to 55.66% the prevalence of this genetic change in our population and adding further support to our previous hypothesis of a founder effect for this mutation in Argentina. Identification of patients with an overt AIP is important because treatment depends on an accurate diagnosis, but more critical is the identification of asymptomatic relatives to avoid acute attacks which may progress to death.

Background: little is known concerning the relation of porphyrias to radiation treatment for cancer. The recent literature does not report negative outcomes at least in single cases of breast cancer, bladder cancer or in a patient with lymphoma. Theoretically, there is a risk for radiation treatment in cases of porphyrias. Case report: two patients with porphyria are described who underwent radiotherapy for glioblastoma multiforme. Case histories, radiation treatment data and the proof of porphyria are given in detail. The patients received a concomitant radiochemotherapy with infusions of ACNU [1-(4-amino-2-methyl-5-pyrimidinyl)-methyl-(2-chloroethyl)-3-nitrosourea] every 6 weeks. The total radiation doses at the ICRU point were 60 and 38 Gy, respectively, given in single daily fractions of 2 Gy. Results: both patients responded well as far as objective tumor regression is concerned but died early after 7 and 1.5 months following diagnosis. The first patient experienced a large brain necrosis and deterioration of her porphyria. The second patient died of cardiopulmonary insufficiency still during radiotherapy with persistent or even increased signs of porphyria. The tumor showed extensive necrosis already after 38 Gy. Conclusion: in view of annotations in the literature and this case report, caution is advised as for irradiation of brain or nervous tissues in case of porphyrias. Molecular biology data seems to support this warning to some extent. (orig.)

We document the presence of a previously unknown species in the urine of patients with acute intermittent porphyria (AIP). The compound was fully characterised by liquid chromatography tandem mass spectrometry. Interpretation of both full spectrum acquisition and product ion spectra acquired in positive and negative ionisation modes by quadrupole time of flight MS allowed for the identification of a condensation product arising from porphobilinogen (PBG, increased in the urine of AIP patients) and indolyl-3-acryloylglycine (IAG, derived from indolylacrylic acid and present in human urine). The structure was unequivocally confirmed through comparison between the selected reaction monitoring chromatograms obtained from the urinary species and the condensation product qualitatively synthesised in the laboratory. Owing to the large amounts of both PBG and IAG in urine of AIP patients, the possible ex vivo formation of PBG-IAG in urine samples was evaluated. The product was spontaneously formed at room temperature, at 4 °C and even during storage at -20 °C when spiking a control sample with PBG. A positive correlation was found between PBG and PBG-IAG in samples collected from AIP patients. However, no correlation was found between PBG-IAG and IAG. Purified PBG-IAG did not form the characteristic chromogen after application of p-dimethylaminobenzaldehyde in HCl, thus suggesting that the current techniques used to measure PBG in urine of AIP patients based on Ehlrich's reaction do not detect this newly characterised PBG-IAG fraction.

Full Text Available Acute intermittent porphyria (AIP is a rare hereditary metabolic disease with an autosomal dominant mode of inheritance. Germline mutations of HMBS gene causes AIP. Mutation of HMBS gene results into the partial deficiency of the heme biosynthetic enzyme hydroxymethylbilane synthase. AIP is clinically manifested with abdominal pain, vomiting, and neurological complaints. Additionally, an extreme phenotypic heterogeneity has been reported in AIP patients with mutations in HMBS gene. Here, we investigated a Chinese patient with AIP. The proband is a 28-year-old Chinese male manifested with severe stomach ache, constipation, nausea and depression. Proband’s father and mother is normal. Proband’s blood sample was collected and genomic DNA was extracted. Whole exome sequencing and Sanger sequencing identified a heterozygous novel single nucleotide deletion (c.809delC in exon 12 of HMBS gene in the proband. This mutation leads to frameshift followed by formation of a truncated (p.Ala270Valfs∗2 HMBS protein with 272 amino acids comparing with the wild type HMBS protein of 361 amino acids. This mutation has not been found in proband’s unaffected parents as well as in 100 healthy normal control. According to the variant interpretation guidelines of American College of Medical Genetics and Genomics (ACMG, this variant is classified as “likely pathogenic” variant. Our findings expand the mutational spectra of HMBS gene related AIP which are significant for screening and genetic diagnosis for AIP.

Full Text Available Purpose: The porphyrias are a defect in the biosynthesis of heme which can be associated with different neurological symptoms during acute attacks such as peripheral neuropathy, mental disturbance and seizures. So far, there have only been a few case reports of status epilepticus, none of which were of epilepsia partialis continua (EPC. We present here two cases of hereditary coproporphyria (HCP manifesting EPC as part of the clinical presentation. Method: The patients' medical charts, EEG and imaging studies were carefully reviewed. Results: Case 1 is a 49-year-old male who first presented a tonic-clonic seizure. Case 2 is a 30-year-old male who came to the emergency room for a convulsive status epilepticus. Both evolved to EPC over the next days. EPC persisted despite several antiepileptic drug trials. Diagnosis of HCP was confirmed by a high level of urine, fecal and serum porphyrins in both cases and by genetic testing in one. Over the last 3 years, the first patient has continued to present non-disabling EPC and has had four tonic-clonic seizures associated with alcohol consumption. The second patient died from brain edema one month and half after admission. Conclusion: Acute porphyrias should be included in the differential diagnosis of new onset status epilepticus, including EPC. Their recognition is important as it modifies significantly patient management, since many anticonvulsants are porphyrogenic.

It has been reported that patients with porphyria cutanea tarda (PCT) develop carbohydrate (CHO) intolerance and manifest diabetes melitus (DM) more frequently than the normal population. In order to verify whether this is due to insulin resistance we studied 5 patients with PCT and 5 normal subjects matched for age, sex and weight. In all the patients an evaluation consisted of the glycemic curve and insulin response to an iv glucose tolerance test (IVGTT: 0.33 g/kg) as well as of an evaluation of the circulating monocyte insulin receptors. Blood samples were drawn in the basal state to measure plasma levels of NEFA, glycerol, and intermediate metabolites. The patients with PCT showed normal glucose tolerance which was obtained, however, at the expense of the elevated insulin levels: therefore a condition of insulin resistance was demonstrated in these subjects. An involvement of the lipid metabolism, observed by the raised levels of plasma NEFA and glycerol, was also evident. The insulin binding to circulating monocytes was reduced but not enough to justify the degree of insulin resistance observed. Therefore, it could be hypothesized, in agreement with similar studies, that a postreceptor defect is responsible for the insulin-resistance observed in patients with PCT and that the reduction of insulin receptors is determined by the down regulation in response to elevated insulinemic levels. An alteration of the porphyrin metabolism might be responsible for this disorder.

Full Text Available Acute intermittent porphyria (AIP is a rare autosomal dominant disorder of heme biosynthesis in liver due to deficiency of porphobilinogen deaminase enzyme. Clinically, AIP is dominatedby a colicky type pain, which does not subside after taking usual analgesics. Additional frequent symptoms are vomiting, hypertension, peripheral neuropathy, seizures, depression, delirium and coma. This paper reported a case of a twenty-fi- ve-year-old female patient, who had undergone a period of six days between the first presentationto the medical department and the diagnosis confirmation. It has accentuated possible mistakes in symptomatic therapy administration as well as dangers of a delayed diagnosis.

The porphyrias are a group of rare metabolic disorders whose diagnosis depends on identification of specific patterns of porphyrin precursor and porphyrin accumulation in urine, blood, and feces. Diagnostic tests for porphyria are performed by specialized laboratories in many countries. Data regarding the analytical and diagnostic performance of these laboratories are scarce. We distributed 5 sets of multispecimen samples from different porphyria patients accompanied by clinical case histories to 18-21 European specialist porphyria laboratories/centers as part of a European Porphyria Network organized external analytical and postanalytical quality assessment (EQA) program. The laboratories stated which analyses they would normally have performed given the case histories and reported results of all porphyria-related analyses available, interpretative comments, and diagnoses. Reported diagnostic strategies initially showed considerable diversity, but the number of laboratories applying adequate diagnostic strategies increased during the study period. We found an average interlaboratory CV of 50% (range 12%-152%) for analytes in absolute concentrations. Result normalization by forming ratios to the upper reference limits did not reduce this variation. Sixty-five percent of reported results were within biological variation-based analytical quality specifications. Clinical interpretation of the obtained analytical results was accurate, and most laboratories established the correct diagnosis in all distributions. Based on a case-based EQA scheme, variations were apparent in analytical and diagnostic performance between European specialist porphyria laboratories. Our findings reinforce the use of EQA schemes as an essential tool to assess both analytical and diagnostic processes and thereby to improve patient care in rare diseases.

Considering economic importance of chlorophyll variegation in floriculture trade an attempt was made for cytological, anatomical and biochemical analysis of four Bougainvillea and Lantana depressa chlorophyll variegated mutants for better and clear understanding of origin of chlorophyll variegation. No cytological evidence could be detected for their origin. Anatomical and biochemical examinations revealed that chlorophyll variegation in these mutants were due to changes in biosynthesis pathways and time of chlorophyll synthesis in palisade and spongy mesophyll cells.

Life span and sequestration of red cells have been studied in twenty one proved cases of acute intermittent porphyria of different age and sex group from Bikaner District, Rajasthan State (India). Chromium-51 labelled red cells were used in the study and the excess count method of Bughe Jones and Szur was used to calculate the index of sequestration. The mean apparent half survival time of erythrocytes in the control subjects was 25.9 +- 2.9 (S.D.) days and the same in the prophyria patients was 27.0 +- 3.8 days. This shows that the life span of red cells is normal in both the patient and the control. Excess destruction of red blood cells was found to take place in either spleen or liver in the disease and no excess accumulation of erythrocytes occurred over spleen as compared to liver. (M.G.B.)

Gunther's disease or congenital erythropoietic porphyria is a rare and severe disorder comprising cutaneous and haemolytic symptoms. Photocutaneous lesions are responsible for scleroderma-like calcifications and deformities of the extremities visible on X-rays. Hemolytic manifestations lead to diffuse major osteopenia. Soft tissue calcifications of the fingers can be seen even in young patients. One case reported here is the first illustration of intracranial calcifications located on dura-mater and calvarium.

Metabolomic profiling combines Nuclear Magnetic Resonance spectroscopy with supervised statistical analysis that might allow to better understanding the mechanisms of a disease. In this study, the urinary metabolic profiling of individuals with porphyrias was performed to predict different types of disease, and to propose new pathophysiological hypotheses. Urine 1 H-NMR spectra of 73 patients with asymptomatic acute intermittent porphyria (aAIP) and familial or sporadic porphyria cutanea tarda (f/sPCT) were compared using a supervised rule-mining algorithm. NMR spectrum buckets bins, corresponding to rules, were extracted and a logistic regression was trained. Our rule-mining algorithm generated results were consistent with those obtained using partial least square discriminant analysis (PLS-DA) and the predictive performance of the model was significant. Buckets that were identified by the algorithm corresponded to metabolites involved in glycolysis and energy-conversion pathways, notably acetate, citrate, and pyruvate, which were found in higher concentrations in the urines of aAIP compared with PCT patients. Metabolic profiling did not discriminate sPCT from fPCT patients. These results suggest that metabolic reprogramming occurs in aAIP individuals, even in the absence of overt symptoms, and supports the relationship that occur between heme synthesis and mitochondrial energetic metabolism.

Full Text Available This work investigated the modulation by melatonin (Mel of the effects of the porphyrinogenic drugs 2-allyl-2-isopropylacetamide (AIA and 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-collidine (DDC on oxidative environment, glucose biosynthesis and heme pathway parameters. Administration of Mel before rat intoxication with AIA/DDC showed a clear beneficial effect in all cases. Mel induced decreases of 42% and 35% in the excretion of the hemeprecursors 5-aminolevulinic acid (ALA and porphobilinogen (PBG, respectively, and a 33% decrease in the induction of the heme regulatory enzyme 5-aminolevulinic acid-synthase (ALA-S. The activity of the glucose metabolism enzyme phosphoenolpyruvate carboxykinase (PEPCK, which had been diminished by the porphyrinogenic treatment, was restored by 45% when animals were pre-treated with Mel. Mel abolished the modest decrease in glucose 6-phospatase (G6Pase activity caused by AIA/DDC treatment. The oxidative status of lipids was attenuated by Mel treatment in homogenates by 47%, whereas no statistically significant AIA/DDC-induced increase in thiobarbituric acid reactive substances (TBARS was observed in microsomes after Mel pre-treatment. We hypothesize that Mel may be scavenging reactive species of oxygen (ROS that could be damaging lipids, PEPCK, G6Pase and ferrochelatase (FQ. Additionally, Mel administration resulted in the repression of the key enzyme ALA-S, and this could be due to an increase in glucose levels, which is known to inhibit ALA-S induction. The consequent decrease in levels of the heme precursors ALA and PBG had a beneficial effect on the drug-induced porphyria. The results obtained open the possibility of further research on the use of melatonin as a co-treatment option in acute porphyria.

Full Text Available The acute hepatic porphyrias are caused by inherited enzymatic deficiencies in the heme biosynthesis pathway. Induction of the first enzyme 5-aminolevulinic acid synthase 1 (ALAS1 by triggers such as fasting or drug exposure can lead to accumulation of neurotoxic heme intermediates that cause disease symptoms. We have demonstrated that hepatic ALAS1 silencing using siRNA in a lipid nanoparticle effectively prevents and treats induced attacks in a mouse model of acute intermittent porphyria. Herein, we report the development of ALN-AS1, an investigational GalNAc-conjugated RNAi therapeutic targeting ALAS1. One challenge in advancing ALN-AS1 to patients is the inability to detect liver ALAS1 mRNA in the absence of liver biopsies. We here describe a less invasive circulating extracellular RNA detection assay to monitor RNAi drug activity in serum and urine. A striking correlation in ALAS1 mRNA was observed across liver, serum, and urine in both rodents and nonhuman primates (NHPs following treatment with ALN-AS1. Moreover, in donor-matched human urine and serum, we demonstrate a notable correspondence in ALAS1 levels, minimal interday assay variability, low interpatient variability from serial sample collections, and the ability to distinguish between healthy volunteers and porphyria patients with induced ALAS1 levels. The collective data highlight the potential utility of this assay in the clinical development of ALN-AS1, and in broadening our understanding of acute hepatic porphyrias disease pathophysiology.

Full Text Available La acumulación de hierro hepático asociada a mutaciones en el gen HFE de la hemocromatosis hereditaria (HH en los pacientes con porfiria cutánea tarda (PCT podría tener un papel en la etiología y en la expresión clínica de esta enfermedad. Se estudió la frecuencia de las mutaciones H63D y C282Y en un grupo de pacientes con PCT y se la comparó con la observada en un grupo de donantes voluntarios de sangre. Los pacientes con PCT fueron catalogados como portadores de la forma hereditaria o adquirida de la enfermedad, según presentaran o no mutaciones en el gen uroporfirinógeno decarboxilasa (UROD. El 50% de los pacientes con PCT eran portadores de la forma genética de la enfermedad, porcentaje significativamente mayor que lo informado en otras series. El 23% de los donantes voluntarios de sangre eran portadores de la mutación H63D y 2.4% lo era de la mutación C282Y. Frecuencias similares a lo encontrado por otros autores en población chilena de etnia blanca, en población argentina y española, pero significativamente más alta que lo encontrado en estudios en población aborigen araucana. Esto tiene, probablemente, relación con el predominio de ascendencia española en la población blanca chilena. La frecuencia de mutación en el gen HFE en pacientes con PCT no fue significativamente diferente que la observada en donantes voluntarios de sangre. Tampoco hubo diferencias significativas en la frecuencia de estas mutaciones entre los casos con PCT adquirida respecto de aquellos en que ésta era de origen genético. Los resultados obtenidos no permiten afirmar que exista asociación entre la PCT y la condición de portador de mutaciones del gen HFE de la hemocromatosis hereditaria.In patients with porphyria cutanea tarda (PCT, hepatic iron accumulation associated to hereditary hemochromatosis (HH could play a role in the etiology and in the clinical expression of the disease.

Previously symptomatic and permanently asymptomatic carriers of a gene mutation for acute intermittent porphyria as well as matched controls were screened with regard to a series of variables of possible relevance to the development of porphyric symptoms. The basis for the study was a concept of acute porphyria as a condition of a permanent system overload of oxidative stress, with long term effects on hepatic and renal tissue, and with instances of periodic overload of free radicals giving rise to acute neurologic involvement. Leukocyte concentrations of manganese, calcium, iron and zinc, as well as erythrocyte calcium differed between the groups, acute intermittent porphyria gene carriers, irrespective of previous porphyric illness, showing significantly higher levels than the controls. Manganese was found to be the most discriminative component of all the 78 variables investigated, accounting for about 98 per cent of the variance between the groups. An increment, by a factor of four, in cellular manganese is suggestive of an increase, in acute intermittent porphyria, of a manganese associated enzyme, e.g. glutamine synthetase, pyruvate carboxylase or mitochondrial superoxide dismutase. The best fit into the model considered is provided by a theory focused on superoxide dismutase, induced in response to superoxide anion radical produced from aminolaevulinic acid. In porphyria gene carriers seemingly resistant to porphyric manifestations, an increase in potentially prooxidant cellular iron is matched by a proportional increment in manganese, i.e. presumably by a corresponding mitochondrial superoxide dismutase induction. This mechanism is not operative in porphyric individuals prone to development of neuropsychiatric symptoms. In acute intermittent porphyria with a history of porphyric illness there is a positive correlation between erythrocyte manganese and serum folate and a negative correlation between leukocyte ferrochelatase activity and serum cobalamin

Variegate darters (Etheostoma variatum) were listed as endangered in Virginia in 1992. Reasons for listing included habitat degradation and concerns about current and future impacts of coal mining throughout their Virginia range. Prior to this research, little was known about variegate darter distribution, habitat use, or populations in Virginia. Two primary goals of this research were to gain knowledge about the current population ecology and the relationship between landscape-level factors (e.g., land cover changes, watershed size, isolation from other populations) on current and past variegate darter population sizes.We investigated distribution, habitat suitability, population genetics, and population size and structure of variegate darters in the upper Big Sandy River drainage, Buchanan, Dickenson, and Wise Co., Virginia. Our results indicate variegate darters are primarily found in the Levisa Fork, with highest densities and abundances between its confluence with Dismal Creek and the Virginia-Kentucky border. Sporadic occurrences in smaller tributaries to the Levisa and Tug forks indicate they exist more widely in low densities, especially near the confluence with the Tug and Levisa mainstems. Detection of variegate darters in smaller tributaries was inconsistent, with reach-level occupancy estimates varying among years. We detected young-of-year variegate darters every year we sampled, but age 1+ darters were indistinguishable from older darters based on standard length.Variegate darter population size and stability in Virginia were estimated via multiple methods, including site occupancy surveys, mark-recapture studies, and population genetic analysis. Using mark-recapture methods at five sites, we estimated overall population size in 2011 to be approximately 12,800 individuals in the 35-km reach between the Levisa Fork - Dismal Creek confluence and the Virginia-Kentucky border. Age structure seemed stable, with breeding adults and young-of-year collected

Full Text Available Porphyria cutanea tarda (PCT is a cutaneous porphyria that presents later in life with cutaneous findings in sun-exposed sites. We report a complex case of PCT in a 67-year-old woman with an unusual constellation of cutaneous findings: scleroderma, acquired ichthyosis, and nonscarring alopecia. Possible triggers for her PCT include tamoxifen treatment for breast cancer and carrier status of the hemochromatosis gene. High-dose chloroquine was used to successfully achieve clinical remission and normalize her uroporphyrins. While on chloroquine she developed extensive classic vitiligo. It is not clear if this is another feature of her complex and unusual PCT, or a consequence of her antimalarial therapy.

A 6-mo-old, male African hedgehog (Atelerix albiventris) presented with a history of pink urine and demonstrating pink-colored teeth and mild hepatomegaly on examination. Urinalysis revealed no physical, chemical, or cellular abnormalities other than a pink color and fluorescence under ultraviolet light (UV). Also under UV, intense fluorescence of teeth, feet, and spines was noted. Porphyria was suspected. Spectrophotometric evaluation of urine showed extremely elevated levels of copro- and uroporphyrins. Analysis of the urine by thin-layer chromatography showed an abnormal pattern of excreted porphyrin intermediates. Urine high-performance thin-layer chromatography showed that excreted porphyrins were 90-95% of the type-I isomeric form, suggestive of congenital erythropoietic porphyria.

Porphyria cutanea tarda (PCT) requires long-term treatment and follow-up, although many patients experience life-long remission. The aim of this cross-sectional postal survey was to describe and investigate the association between illness perception, health complaints, self-reported symptoms and distress in persons with PCT. The participants perceived PCT as a chronic condition with high levels of personal and treatment control. Persons who reported active symptoms scored higher on perceived illness threat, total health complaints and psychological distress compared with those in remission or latent phases. However, a higher perception of illness threat and the total burden of health complaints were more closely associated with psychological distress than were perceived PCT symptoms activity. This has implications for clinical consultation; dermatologists should be attentive to symptoms activity, but also recognize that patients in remission with a high perceived illness threat and multiple health complaints might be especially vulnerable to psychological distress with regards to PCT.

Reversible posterior leukoencephalopathy syndrome (PLS) is characterized by headache, altered mental function, visual disturbances and seizures. Neuroimaging studies suggest a white-matter oedema, predominantly in the posterior parietal-temporal-occipital regions of the brain. We present the case of a 30-year-old woman who had suffered her first attack of acute intermittent porphyria (AIP). Following 1 week of abdominal pain she developed several generalized seizures, and hallucinations, and exhibited a progressive deterioration of the consciousness. T2-weighted images, especially fluid-attenuated inversion recovery (FLAIR) sequences showed bilateral lesions in the posterior frontal, parietal and occipital cortex and subcortical white matter. Following treatment with haematin and a high carbohydrate diet the patient's condition improved. Follow-up magnetic resonance imaging (MRI) revealed complete resolution of the lesions. To our knowledge, this is the first report concerning a completely reversible PLS in AIP. (orig.)

Full Text Available Background Porphyria Cutanea Tarda (PCT is a metabolic disorder resulting from a deficiency of hepatic enzyme uroporphyrinogen decarboxylase (UROD. UROD deficiency results in the accumulation of porphyrins, which are phototoxic and hepatotoxic. PCT patients are at increased risk of developing hepatocellular carcinoma. Aims We aim to describe a series of PCT patients presenting to a tertiary center over 35-year period from the 1980s to December 2015 and review current literature to date on PCT, with a focus on PCT management. Methods A search of the center’s dermatology department and biochemistry database were performed to identify patients diagnosed with PCT. Demographic data, underlying risk factors and management details were obtained. Statistical tests were performed to identify any possible association between the variables of interest. Results 34 patients were included in this study. Mean age of diagnosis was 48 years and there was no gender difference. 12 patients had Hepatitis C infection, 25 had excessive alcohol consumption, 13 had hereditary haemochromatosis. Eight patients developed oestrogen-associated or hormonal replacement therapy (HRT induced PCT. 33 patients (97 per cent responded to venesection. Six (18 per cent patients were prescribed hydroxychloroquine, either alone or concurrently with venesection. They all achieved remission. Average duration of follow up is 13 years. One patient developed hepatocellular carcinoma (HCC. Conclusion Our study has reinforced venesection as an effective treatment for PCT. Low dose hydroxychloroquine can be used in patients where venesection is contraindicated or not tolerated. General measures such as alcohol abstinence, visible violet light protection and trauma avoidance are recommended.

To examine the role of hemochromatosis (HFE) gene mutations, which are associated with porphyria cutanea tarda (PCT), in the therapeutic response to chloroquine. We retrospectively analyzed a database (Excel version 2001 [Microsoft Excel, Redmond, Wash]; date range of search, 1985-1999) of chloroquine-treated patients with PCT on whether HFE mutations (C282Y and H63D) might have influenced the clinical response, urinary porphyrin excretion, liver enzyme activities, and serum iron markers. Serum samples and corresponding complete sets of data before and after therapy were available in 62 of 207 patients with PCT who were treated exclusively with chloroquine. Academic teaching hospital. For treatment, low-dose chloroquine diphosphate, 125 to 250 mg twice weekly, was used during a median time of 16 months (range, 12-26 months). Of the 62 German patients with PCT, 37 (60%) carries HFE mutations. Chloroquine therapy was accompanied by clinical remission and reduced urinary porphyrin excretion (P<.001) in the 24 patients (39%) with HFE wild type as well as in 35 HFE heterozygous patients with PCT (56%). Decreases of serum iron markers following chloroquine therapy were limited to patients with PCT and HFE wild type. All patients homozygous for the C282Y mutation (3 [5%] of 62) had high serum iron, ferritin, and transferrin saturation and failed to respond to chloroquine treatment. The therapeutic response to chloroquine was not compromised by C282Y heterozygosity and compound heterozygosity of HFE mutations. Because HFE C282Y homozygotes (+/+) did not respond to chloroquine and a decrease in serum iron concentration was limited to patients with PCT and HFE wild type, phlebotomy should be first-line therapy in patients with PCT and HFE mutations.
Full Text Available The leaf-explants of Saintpaulia ionantha Wendl. var.'miniature' were treated by different doses of MNH and cultured on shoot regeneration medium. A strong toxic effect of some MNH doses on explant survival during the first two subcultures was noticed. The explants surviving treatment regenerated shoots with the efficiency comparable to the control. The high number of shoots regenerated from mutagenised leaves showed chlorophyll chimerism (so-called variegated forms. The use of 5 mM MNH for 1.5 or 2 h was found very effective, as 100% of survived explants regenerated variegated shoots. Besides hundreds of variegated forms also leaf-shape and flower-colour variants were observed in MNH-treated culture. Somaclonal variation was not observed in the control culture. The results indicate the great efficiency of in vitro applied MNH for in-duction of morphological variants of Saintpaulia, and especially variegated forms.
Full Text Available Leaf variegation is often the focus of plant breeding. Here, we studied a variegated mutant of Phalaenopsis aphrodite subsp. formosana, which is usually used as a parent of horticultural breeding, to understand its anatomic and genetic regulatory mechanisms in variegation. Chloroplasts with well-organized thylakoids and starch grains were found only in the mesophyll cells of green sectors but not of yellow sectors, confirming that the variegation belongs to the chlorophyll type. The two-dimensional electrophoresis and LC/MS/MS also reveal differential expressions of PsbP and PsbO between the green and yellow leaf sectors. Full-length cDNA sequencing revealed that mutant transcripts were caused by intron retention. When conditioning on the total RNA expression, we found that the functional transcript of PsbO and mutant transcript of PsbP are higher expressed in the yellow sector than in the green sector, suggesting that the post-transcriptional regulation of PsbO and PsbP differentiates the performance between green and yellow sectors. Because PsbP plays an important role in the stability of thylakoid folding, we suggest that the negative regulation of PsbP may inhibit thylakoid development in the yellow sectors. This causes chlorophyll deficiency in the yellow sectors and results in leaf variegation. We also provide evidence of the link of virus CymMV and the formation of variegation according to the differential expression of CymMV between green and yellow sectors.
Full Text Available A 28-year-old presented with complaints of severe pain and redness in the left eye since 2 weeks. He had similar complaints in the right eye 2 years back for which he had undergone a scleral patch graft. Best corrected visual acuity was 20/20 in both eyes. The right had a well vascularized scleral graft and rest of the anterior segment was normal. The left eye had inferior conjunctival congestion with an area of the scleral melt with uveal show just temporal to the limbus in the interpalbebral area. The cornea was clear and anterior chamber was quiet in the left eye. Applanation tonometry and fundus evaluation were normal in both eyes. Physical examination revealed hyperpigmented skin lesion, hypertrichosis and absorption of distal phalanges. Laboratory, ocular and physical findings confirmed the diagnosis of congenital erythropoietic porphyria. He was on oral steroids 40 mg/day since 2 weeks and topical antibiotics and lubricants. He was advised to continue the same and was taken up for scleral patch graft with fibrin glue in the left eye. Postoperatively he was continued on topical and oral steroids and lubricants.3 weeks later the left eye had stabilized however patient came with a melt in the right eye. Since it was an early melt, we went ahead with cyanoacrylate glue and bandage contact lens in the right eye and started him on topical steroids for the right eye also. Three months later both the eyes were stable, and the patient was gradually tapered off the steroids.
Full Text Available Chronic kidney disease is a long-term complication in acute intermittent porphyria (AIP. The pathophysiological significance of hepatic overproduction of the porphyrin precursors aminolevulinate acid (ALA and porphobilinogen (PBG in chronic kidney disease is unclear. We have investigated the effect of repetitive acute attacks on renal function and the effect of total or five-sixth nephrectomy causing renal insufficiency on hepatic heme synthesis in the porphobilinogen deaminase (PBGD-deficient (AIP mouse. Phenobarbital challenge in the AIP-mice increased urinary porphyrin precursor excretion. Successive attacks throughout 14 weeks led to minor renal lesions with no impact on renal function. In the liver of wild type and AIP mice, 5/6 nephrectomy enhanced transcription of the first and rate-limiting ALA synthase. As a consequence, urinary PBG excretion increased in AIP mice. The PBG/ALA ratio increased from 1 in sham operated AIP animals to over 5 (males and over 13 (females in the 5/6 nephrectomized mice. Total nephrectomy caused a rapid decrease in PBGD activity without changes in enzyme protein level in the AIP mice but not in the wild type animals. In conclusion, high concentration of porphyrin precursors had little impact on renal function. However, progressive renal insufficiency aggravates porphyria attacks and increases the PBG/ALA ratio, which should be considered a warning sign for potentially life-threatening impairment in AIP patients with signs of renal failure.

Full Text Available La PCT es la más común de las porfirias. Es una fotodermatosis que resulta de la deficiencia de la UPD, enzima perteneciente a la vía de síntesis del hemo. Presentamos la evolución de cinco casos de PCT; cuatro de PCT familiar y uno de PCT esporádica. En dos de los pacientes pertenecientes al grupo de PCT tipo II, encontramos como factor de riesgo, el consumo de alcohol, y en la paciente con PCT tipo I se detectó serología positiva para VHC. Todos los pacientes fueron tratados con cloroquina y flebotomías repetidas. Rápidamente se detectó mejoría clínica y bioquímica. Se observó que la porfirinuria continuó en descenso aún luego de suspendida la terapéutica. Tres de los pacientes con PCT familiar persisten en remisión clínica y con ausenciade recaídas tras más de 10 años de seguimiento. Aconsejamos en pacientes que padecen PCT la búsqueda de factores asociados (VHC, HIV, genes de HH y desencadenantes exógenos (consumo excesivo de alcohol, hierro en la dieta e ingesta de estrógenos que de ser controlados o evitados, junto con el tratamiento oportuno, contribuyen a un satisfactorio control de la enfermedad.The porphyria cutanea tarda is the most frequent porphyria, it is a photodermatosis secondary to uroporphyrinogen decarboxylase deficiency; this enzyme belongs to the haem synthesis pathway. We present on this paper the evolution of five cases of PCT, four of them with familiar type and one of them sporadic type. In two patients belonging to PCT type II, we found alcohol addiction as a serious risk, while on the other patients PCT type I we found HCV positive serology. All patients were treated with chloroquine and phlebotomies. We could observe a good response not only clinical but biochemical. We could also see that the porphyrins urinary level continued descending once the drug was withdrew. Three of the patients with familiar PCT remains in clinical remission without any relapses in ten years of control. We advice
Full Text Available Lead poisoning (LP is less commonly encountered in emergency departments (ED. However, lead exposure still occurs, and new sources of poisoning have emerged. LP often goes unrecognized due to a low index of suspicion and nonspecific symptoms. We present a case of a 48-year-old man who had recurring abdominal pain with anemia that was misdiagnosed. His condition was initially diagnosed as nonspecific abdominal pain and acute porphyria. Acute porphyria-like symptoms with a positive urine porphyrin test result led to the misdiagnosis; testing for heme precursors in urine is the key to the differential diagnosis between LP and acute porphyria. The final definitive diagnosis of lead toxicity was confirmed based on high blood lead levels after detailed medical history taking. The lead poisoning was caused by traditional Chinese herbal pills. The abdominal pain disappeared after a course of chelating treatment. The triad for the diagnosis of lead poisoning should be a history of medicine intake, anemia with basophilic stippling, and recurrent abdominal pain.

Full Text Available Acute intermittent porphyria (AIP and ichthyosis vulgaris both are autosomal dominant disorders with incomplete penetrance caused by the deficiency of porphobilinogen deaminase enzyme and filaggrin protein, respectively. We report a rare case of a 9-year-old boy having two genetic diseases with an unclear association. An acute attack of AIP is characterized by gastrointestinal symptoms and neuropsychiatric manifestations. Although rare in the first decade of life, the presence of reddish urine with a typical presentation such as abdominal pain, hypertension, seizure, and paresthesias lead us to the diagnosis of AIP. The precipitating factor in the present case was prolonged fasting in Ramadan.

caso de porfiria aguda intermitente no pós-operatório de cirurgia bariátrica.Acute intermittent porphyria is an unusual pathology with potentially severe consequences when not early detected. Among the possible causes of porphyric crises decrease of caloric intake has been described. A case of acute intermittent porphyria in the late postoperative period of a bariatric surgery performed for treatment of obesity is reported. A review of the diagnostic aspects and management of this pathology in the intensive care unit follows. A 31 year old woman was admitted in the intensive care unit three weeks after a bariatric surgery, with decreased level of consciousness and respiratory distress. The patient evolved with psychomotor agitation, mental confusion, abdominal pain and proximal tetraparesis. Diagnosis investigation disclosed severe hyponatremia (92mEq/L, hypomagnesemia, hypophosfatemia and hypocalcemia and cloudy urine without hematuria. Acute porphyria was suspected and the urine test detected high delta amino-levulinic acid and porphobilinogen. Treatment consisted of a correction of electrolyte disturbances and high carbohydrate intake. Hematin and heme arginate were not used, due to the difficulty to acquire the medication. After 8 months the patient progressed with full recovery of muscle strength and a clinical improvement. Acute intermittent porphyria has signs and symptoms common to several clinical, neurological, psychiatric and gastroenterological pathologies, which complicate diagnosis. Therefore, acute intermittent porphyria should be included in the differential diagnosis of neurological, psychiatric and gastroenterological alterations when results of all other exams are normal. Attention must be given to patients undergoing surgery mainly bariatric that, in addition to procedure stress, substantially limit the total caloric intake, potentially triggering crises. Review of literature did not disclose any report of acute intermittent porphyria crisis

Vincent van Gogh suffered from recurrent bouts of an illness that may have been acute porphyria and abused camphor and alcohol, the latter particularly in the form of absinthe, a liqueur distilled from wormwood that was popular in 19th C France. To learn whether camphor or terpenes found in absinthe are porphyrogenic, the authors studied them in cultures of chick embryo liver cells. All were found to be porphyrogenic, especially in the presence of deferoxamine. The terpenes also induced the activity and protein amount of 5-aminolevulinate synthase and heme oxygenase, and induced activities of benzphetamine demethylase. The degree of porphyrin and enzyme induction produced by 1mM camphor was similar to that produced by 50uM glutethimide, a potent porphyrogen. Potency of pinene and thujone were lower. Camphor and glutethimide both produced accumulations of 8- and 7-COOH porphyrins, whereas pinene and thujone produced 4- and 2-COOH porphyrin accumulation. The authors conclude that camphor, pinen and thujone are porphyrogenic, cable of exacerbating acute porphyria, and may have done so in van Gogh.

Gene repression is crucial to the maintenance of differentiated cell types in multicellular organisms, whereas aberrant silencing can lead to disease. The organization of DNA into chromatin and heterochromatin is implicated in gene silencing. In chromatin, DNA wraps around histones, creating nucleosomes. Further condensation of chromatin, associated with large blocks of repetitive DNA sequences, is known as heterochromatin. Position effect variegation (PEV) occurs when a gene is located abnormally close to heterochromatin, silencing the affected gene in a proportion of cells. Here we show that the relatively short triplet-repeat expansions found in myotonic dystrophy and Friedreich's ataxia confer variegation of expression on a linked transgene in mice. Silencing was correlated with a decrease in promoter accessibility and was enhanced by the classical PEV modifier heterochromatin protein 1 (HP1). Notably, triplet-repeat-associated variegation was not restricted to classical heterochromatic regions but occurred irrespective of chromosomal location. Because the phenomenon described here shares important features with PEV, the mechanisms underlying heterochromatin-mediated silencing might have a role in gene regulation at many sites throughout the mammalian genome and modulate the extent of gene silencing and hence severity in several triplet-repeat diseases.
Full Text Available A variegação das fôlhas do cafeeiro tanto em plantas novas como em plantas adultas tem sido freqüentemente observada. Plantas variegadas podem ocorrer espontaneamente nas progénies das diversas variedades de Coffea arabica L., motivo porque não devem constituir variedade distinta dessa espécie, como foi proposto por Cramer. As plantas variegadas em estudo puderam ser agrupadas em duas categorias, isto é, aquelas em que a variegação não se acha associada com anomalias na forma e textura das folhas e aquelas nas quais a variegação é acompanhada dessas anomalias. No primeiro grupo o padrão de variegação não é uniforme para tôdas as fôlhas, enquanto no segundo grupo o padrão é semelhante para tôda a planta. Usualmente apenas alguns ramos das plantas do primeiro grupo são variegados. Observou-se algumas vezes que as duas fôlhas do mesmo verticilo têm padrões semelhantes de variegação. Encontraram-se também fôlhas variegadas nas quais a metade da lâmina é variegada ou mesmo albina, enquanto a outra metade apresenta a côr verde normal. Os dados genéticos obtidos, embora preliminares para a maioria das plantas variegadas em investigação, permitiram concluir que o padrão de variegação da planta 180, pertencente ao primeiro grupo, é herdado pelo citoplasma e não é transmitido pelo pólen. O padrão de variegação da planta 253-21, pertencente ao segundo grupo, no entanto, parece ser transmitido pelo polen.Leaf variegation in coffee plants is a relatively common abnormality, and variegated seedlings have been found to occur spontaneously in progenies of most varieties of Coffea arabica L. For this reason it is thought that variegated types should not be described as distinct varieties, as it was done before by Cramer. Variegated coffee plants can be grouped in two categories : first, those in which variegated leaves are normal in shape and texture, but do not show a uniform variegation pattern; and second, those
Full Text Available Malignant gliomas account for 35-45% of primary brain tumors; among these glioblastoma multiforme (GBM is the most common adult brain tumor constituting approximately 85%. Its incidence is quite less in the pediatric population and treatment of these patients is particularly challenging. Exposure to ionizing radiation is the only environmental factor found to have any significant association with GBM. Several genetic alterations associated with GBM in adults have been well documented such as epidermal growth factor receptor amplification, overexpression of mouse double minute 2 homolog also known as E3 ubiquitin-protein ligase, Phosphatase and tensin homolog gene mutation, loss of heterozygosity of chromosome 10p and isocitrate dehydrogenase-1 mutation. However, data on genetic mutations in pediatric GBM is still lacking. Exophytic brain stem gliomas are rare tumors and are usually associated with a poor prognosis. The most effective treatment in achieving long-term survival in such patients, is surgical excision of the tumor and then chemoradiotherapy followed by adjuvant chemotherapy by temozolomide. This schedule is the standard treatment for GBM patients. In view of the rarity of pediatric GBM, we report here a case of pontine GBM in a 5-year-old girl.

In the T(1;2)dor(var7) translocation, the 1A-2B7-8 segment of the X chromosome is brought to the vicinity of 2R-chromosome heterochromatin resulting in position effect variegation of dor, BR-C and more distal genes, as well as compaction of chromatin in this segment. By irradiation of T(1;2)dor(var7), nine reversions (rev) to a normal phenotype were recovered. In two cases (rev27, rev226), the 1A-2B7-8 section is relocated to the 19A region of the X chromosome, forming free duplications (1A-2...

The VAR3 gene, isolated by transposon tagging, encodes the 85.9 kDa VAR3...... that pigment profiles are qualitatively similar in wild type and var3, although var3 accumulates lower levels of chlorophylls and carotenoids. These results indicate that VAR3 is a part of a protein complex required for normal chloroplast and palisade cell development....

Hexachlobenzene (HCB), one of the most persistent environmental pollutants, induces porphyria cutanea tarda (PCT). The aim of this work was to analyze the effect of HCB on some aspects of glucose metabolism, particularly those related to its neosynthesis in vivo. For this purpose, a time-course study on gluconeogenic enzymes, pyruvate carboxylase (PC), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphatase (G-6-Pase) and on pyruvate kinase (PK), a glycolytic enzyme, was carried out. Plasma glucose and insulin levels, hepatic glycogen, tryptophan contents, and the pancreatic insulin secretion pattern stimulated by glucose were investigated. Oxidative stress and heme pathway parameters were also evaluated. HCB treatment decreased PC, PEPCK, and G-6-Pase activities. The effect was observed at an early time point and grew as the treatment progressed. Loss of 60, 56, and 37%, respectively, was noted at the end of the treatment when a considerable amount of porphyrins had accumulated in the liver as a result of drastic blockage of uroporphyrinogen decarboxylase (URO-D) (95% inhibition). The plasma glucose level was reduced (one-third loss), while storage of hepatic glucose was stimulated in a time-dependent way by HCB treatment. A decay in the normal plasma insulin level was observed as fungicide intoxication progressed (twice to four times lower). However, normal insulin secretion of perifused pancreatic Langerhans islets stimulated by glucose during the 3rd and 6th weeks of treatment did not prove to be significantly affected. HCB promoted a time-dependent increase in urinary chemiluminiscence (fourfold) and hepatic malondialdehide (MDA) content (fivefold), while the liver tryptophan level was only raised at the longest intoxication times. These results would suggest that HCB treatment does not cause a primary alteration in the mechanism of pancreatic insulin secretion and that the changes induced by the fungicide on insulin levels would be an adaptative

Acute intermittent porphyria (AIP) is an autosomal-dominant inborn error of metabolism that results from the half-normal activity of the third enzyme in the heme biosynthetic pathway, hydroxymethylbilane synthase (HMB-synthase). AIP is an ecogenetic condition, since the life-threatening acute attacks are precipitated by various factors, including drugs, alcohol, fasting, and certain hormones. Biochemical diagnosis is problematic, and the identification of mutations in the HMB-synthase gene provides accurate detection of presymptomatic heterozygotes, permitting avoidance of the acute precipitating factors. By direct solid-phase sequencing, two mutations causing AIP were identified, an adenine deletion at position 629 in exon 11(629delA), which alters the reading frame and predicts premature truncation of the enzyme protein after amino acid 255, and a nonsense mutation in exon 12 (R225X). These mutations were confirmed by either restriction enzyme analysis or family studies of symptomatic patients, permitting accurate presymptomatic diagnosis of affected relatives. 29 refs., 2 figs.

Direct and indirect mechanisms underlying the light response of stomata were studied in variegated leaves of the juvenile phase of Hedera helix L. Dose response curves of leaf conductance were measured with blue and red light in leaves kept in normal or in an inverted position. In the green portions of the leaves, the sensitivity to blue light was nearly 100 times higher than that to red light. No response to red light was observed in the white portions of the leaves up to 90 micromoles per square meter per second. Red light indirectly affected leaf conductance while blue light had a direct effect. Leaf conductance was found to be more sensitive to drought stress and showed a more persistent aftereffect in the white portions of the leaves. A differential effect of drought stress on the responses to blue and red light was also observed. PMID:16664900

Full Text Available Catharanthus roseus is a perennial, evergreen herb in the family Apocynaceae, which is used as ornamental and for popular medicine to treat a wide assortment of human diseases. This paper describes a new potyvirus found causing mosaic symptom, foliar malformation and flower variegation in C. roseus. Of 28 test-plants inoculated mechanically with this potyvirus, only C. roseus and Nicotiana benthamiana developed systemic mosaic, whereas Chenopodium amaranticolor and C. quinoa exhibited chlorotic local lesions. The virus was transmitted by Aphis gossypii and Myzus nicotianae. When the nucleotide sequence of the CP gene (768nt was compared with other members of the Potyviridae family, the highest identities varied from 67 to 76 %. For the 3' UTR (286nt, identities varied from 16.8 to 28.6 %. The name Catharanthus mosaic virus (CatMV is proposed for this new potyvirus.
Full Text Available Scope of this study is to demonstrate an old theory expressed in 1963, when Illis (Guy’s Hospital in London established a correlation between the clinical lycanthropy and congenital porphyria cutanea tarda. We had the fortune to live in a village where they say a lycanthrope lives too and is accustomed to hid himself at home for the 3 days when on the full moon, when he becomes (and behaves as a werewolf. Werewolves like to walk around before dawn craving for water and since We love to walk very early in the morning (as philosopher Emanuel Kant used to do, We have had this chance to encounter this mysterious man, who is a normal man with a regular lifestyle according to lunar cycle. He presents a very pale face with scares and blisters and generally when somebody asks him about this cutaneous manifestations he says he detests sun and light and his skin reacts by this way. We attempted to treat this individual by a pomade containing rutin, diosmin,Centella asiatica,niacinamide and escin. Results are encouraging as well.

Full Text Available Las porfirias son consecuencia de fallas en el metabolismo del hemo. Se clasifican según el tipo de sintomatología clínica prevalente o el órgano donde se expresa preferencialmente la falla metabólica. En general la deficiencia enzimática está asociada a mutaciones en los genes que codifican para cada una de las enzimas. Están descritos 7 tipos de porfiria diferentes. Se transmiten por carácter autosómico dominante a excepción de la PCE, la PHE y la NPA que son recesivas. Sin embargo, están reportadas variantes homocigotas para el resto de las porfirias de pronóstico y evolución mucho más grave que la forma heterocigota. La descripción de estos casos poco frecuentes, sus tratamientos y evolución, facilitarían tanto el diagnóstico diferencial de la porfiria como el conocimiento de las posibilidades terapéuticas en cada caso. Asimismo para las porfirias heterocigotas con manifestación infantil, su identificación temprana y tratamiento aseguraría una mejor evolución minimizando los riesgos asociados. Se han diagnosticado 5 casos de porfirias agudas en niñas: 2 de PAI, 2 de PV y 1 de CPH. Entre las porfirias cutáneas se presentan 25 casos de PCT infantil, el primer caso de PHE en Argentina, 4 casos de PCE infantil y 1 en un adulto y 2 casos de PPE con compromiso hepatobiliar.The Porphyrias are a group of diseases resulting from partial deficiencies in one of the heme biosynthetic enzymes.

In this study, impacts of O 3 on four cultivars ('Rose', 'Pink', 'Blush' and 'White') of the polka dot plant with variegated leaves were investigated for the first time. Ozone fumigation [(120 ± 20 ppb) for 14 days (8 h day -1 , from 8:30 to 16:30)] resulted in visible foliar injuries, decreased contents of pigments (chlorophyll a and b, and carotenoid), the inhibition of photosynthesis, the increase of quantum yield of non-regulated heat dissipation and fluorescence emission (Y(NO)), and the damage of cell membrane. Elevated O 3 increased the content of anthocyanin (Ant). 'White' showed the highest, and 'Rose' the lowest amount of injured leaf area, indicating that the former was the most sensitive, and the latter the most tolerant to O 3 stress. After O 3 exposure, the highest Ant content was found in 'Rose', followed by 'Pink', 'Blush', and 'White'. Levels of Ant were likely responsible for the different sensitivities to O 3 due to their roles in photoprotection.

Huanglongbing (HLB) and citrus variegated chlorosis (CVC) are serious threats to citrus production and have caused considerable economic losses worldwide, especially in Brazil, which is one of the biggest citrus producers in the world. Neither disease has a cure nor an efficient means of control. They are also generally confused with each other in the field since they share similar initial symptoms, e.g., yellowing blotchy leaves. The most efficient tool for detecting these diseases is by polymerase chain reaction (PCR). However, PCR is expensive, is not high throughput, and is subject to cross reaction and contamination. In this report, a diagnostic method is proposed for detecting HLB and CVC diseases in leaves of sweet orange trees using attenuated total reflectance Fourier transform infrared spectroscopy and the induced classifier via partial least-squares regression. Four different leaf types were considered: healthy, CVC-symptomatic, HLB-symptomatic, and HLB-asymptomatic. The results show a success rate of 93.8% in correctly identifying these different leaf types. In order to understand which compounds are responsible for the spectral differences between the leaf types, samples of carbohydrates starch, sucrose, and glucose, flavonoids hesperidin and naringin, and coumarin umbelliferone were also analyzed. The concentration of these compounds in leaves may vary due to biotic stresses. Copyright Â© 2012 Elsevier B.V. All rights reserved.
Porfiria cutánea tarda: asociación con mutaciones HFE, hepatitis virales, alcohol y otros factores de riesgo en Guipúzcoa, País Vasco Porphyria cutanea tarda: An analysis of HFE gene mutations, hepatitis viruses, alcohol intake, and other risk factors in 54 patients from Guipúzcoa, Basque Country, Spain

Sweet pea ( Lathyrus odoratus L.) is a major cut flower in Japan, generally grown in greenhouses in winter to spring. The wild-type sweet pea is a long-day summer-flowering plant. The day-neutral winter-flowering ability, which allows cut-flower production in Japan, is a recessive phenotype that emerged by spontaneous mutation. Although Japanese winter-flowering cultivars and additionally spring-flowering cultivars, which have semi-long-day flowering ability generated by crossing the winter- and summer-flowering cultivars, have superior phenotypes for cut flowers, they have limited variation in color and fragrance. In particular, variegated phenotypes do not appear in modern winter- and spring-flowering cultivars, only in summer-flowering cultivars. We try to expand the phenotypic diversity of Japanese cut flower cultivars. In the processes, we introduced the variegated phenotypes by crossing with summer-flowering cultivars, and succeeded in breeding some excellent cultivars. During breeding, we analyzed the segregation ratios and revealed the heredity of the phenotypes. Here we review the heredity of these variegated phenotypes and winter-flowering phenotypes and their related genes. We also describe how we introduced the trait into winter-flowering cultivars, tracing their pedigrees to show both phenotypes and genotypes of the progeny at each generation. This knowledge is useful for the efficient breeding of new variegated cultivars.

Full Text Available The variegated grasshopper Zonocerus variegatus is a polyphagous insect, feeding on numerous food and cash crops. The present study aimed to investigate the sexual variations in the destructive capability of the adult insects and the composition of leaves damaged by them, as well as in the levels of midgut microbial flora and digestive enzymes (cellulase, amylase and α-glucosidase. The results showed that females consumed and caused more damage to cassava leaves than their male congeners. The leaves damaged by males contained more nutrients than those damaged by females. The gut microbial flora and enzyme assay showed that females had significantly larger colony forming units and a non-significant difference in enzyme activities. It can thus be concluded that adult females are more destructive than males.
Full Text Available Variegated Glacier (Alaska is known to surge periodically after a sufficient amount of cumulative mass balance is reached, but this observation is difficult to link with changes in the basal conditions. Here, using a 10-yr dataset, consisting of surface topography and surface velocity observations along a flow line for 25 dates, we have reconstructed the evolution of the basal conditions prior to and during the 1982–1983 surge. The model solves the full-Stokes problem along the central flow line using the finite element method. For the 25 dates of the dataset, the basal friction parameter distribution is inferred using the inverse method proposed by Arthern and Gudmundsson (2010. This method is here slightly modified by incorporating a regularisation term in the cost function to avoid short wavelength changes in the friction parameter. Our results indicate that dramatic changes in the basal conditions occurred between 1973 to 1983. Prior to the surge, periodic changes can be observed between winter and summer, with a regular increase of the sliding from 1973 to 1982. During the surge, the basal friction decreased dramatically and an area of very low friction moved from the upper part of the glacier to its terminus. Using a more complex friction law, these changes in basal sliding are then interpreted in terms of basal water pressure. Our results support that dramatic changes took place in the subglacial drainage system of Variegated Glacier, moving from a relatively efficient drainage system prior to the surge to an inefficient one during the surge. By reconstructing the water pressure evolution at the base of the glacier it is possible to propose a scenario for the hydrological history leading to the occurrence of a surge.

A filter paper dry blood spot procedure for the determination of whole blood uroporphyrinogen-I-synthase (UIS) activity is presented. The method is based on the concept of enzyme specific activity, the enzyme activity being related to the haemoglobin concentration of the assay sample. The diagnostic capacity with regard to the acute intermittent porphyria (AIP) gene carrier state is shown to be equivalent to that of a washed red cell reference method. On grounds of easy capillary blood sampling, uncomplicated and safe mail specimen transport and simple laboratory reception routines, the method is stated to be well adapted for use in AIP preadolescent population screening.

Leaf variegation mutants constitute a unique group of chloroplast development mutants and are ideal genetic materials to dissect the regulation of chloroplast development. We have utilized the Arabidopsis yellow variegated (var2) mutant and genetic suppressor analysis to probe the mechanisms of chloroplast development. Here we report the isolation of a new var2 suppressor locus SUPPRESSOR OF VARIEGATION (SVR10). Genetic mapping and molecular complementation indicated that SVR10 encodes a circularly permuted GTPase that has been reported as Arabidopsis thaliana NITRIC OXIDE ASSOCIATED 1 (AtNOA1) and RESISTANT TO INHIBITION BY FOSMIDOMYCIN 1 (RIF1). Biochemical evidence showed that SVR10/AtNOA1/RIF1 likely localizes to the chloroplast stroma. We further demonstrate that the mutant of a close homologue of SVR10/AtNOA1/RIF1, BRASSINAZOLE INSENSITIVE PALE GREEN 2 (BPG2), can also suppress var2 leaf variegation. Mutants of SVR10 and BPG2 are impaired in photosynthesis and the accumulation of chloroplast proteins. Interestingly, two-dimensional blue native gel analysis showed that mutants of SVR10 and BPG2 display defects in the assembly of thylakoid membrane complexes including reduced levels of major photosynthetic complexes and the abnormal accumulation of a chlorophyll-protein supercomplex containing photosystem I. Taken together, our findings suggest that SVR10 and BPG2 are functionally related with VAR2, likely through their potential roles in regulating chloroplast protein homeostasis, and both SVR10 and BPG2 are required for efficient thylakoid protein complex assembly and photosynthesis.

Full Text Available Knowledge of ecological impacts of exotic beach almond (Terminalia catappa in the central Pacific of Costa Rica are little known, but studies have found this species to be a potentially important food source for endangered scarlet macaws (Ara macao. In this study, reproductive phenology and seed predation by variegated squirrels (Sciurus variegatoides and scarlet macaws were measured during March and April 2011 on beaches of central Pacific coastal Costa Rica. Seed productivity and predation levels were quantified on a weekly basis for 111 beach almond trees to assess the importance of beach almond as a food source for scarlet macaws and the extent of resource partitioning between seed predators. Seed production of the trees was great (about 194 272 seeds and approximately 67% of seeds were predated by seed predators. Macaws consumed an estimated 49% of seeds while squirrels consumed 18%. Additionally, evidence of resource partitioning between squirrels and macaws was found. Scarlet macaws preferred to feed on the northern side and edge of the canopy while squirrels preferred to feed on the southern and inside parts of the canopy. Both species ate most seeds on the ocean side of the tree. Despite the status of this tree as an exotic species, the beach almond appears to be an important resource for scarlet macaw population recovery. The resource produced by this tree should be taken into account as reforestation efforts continue in Costa Rica. Rev. Biol. Trop. 62 (3: 929-938. Epub 2014 September 01.

Citrus are among the economically most important fruit tree crops in the world. Citrus variegated chlorosis (CVC), caused by Xylella fastidiosa infection, is a serious disease limiting citrus production at a global scale. With availability of citrus genomic resources, it is now possible to compare citrus expressed sequence tag (EST) data sets and identify single-nucleotide polymorphisms (SNPs) within and among different citrus cultivars that can be exploited for citrus resistance to infections, citrus breeding, among others. We report here, for the first time, SNPs in the EST data sets of X. fastidiosa-infected Citrus sinensis (sweet orange) and their functional annotation that revealed the involvement of eight C. sinensis candidate genes in CVC pathogenesis. Among these genes were xyloglucan endotransglycosylase, myo-inositol-1-phosphate synthase, and peroxidase were found to be involved in plant cell wall metabolism. These have been further investigated by molecular modeling for their role in CVC infection and defense. Molecular docking analyses of the wild and the mutant (SNP containing) types of the selected three enzymes with their respective substrates revealed a significant decrease in the binding affinity of substrates for the mutant enzymes, thus suggesting a decrease in the catalytic efficiency of these enzymes during infection, thereby facilitating a favorable condition for infection by the pathogen. These findings offer novel agrigenomics insights in developing future molecular targets and strategies for citrus fruit cultivation in ways that are resistant to X. fastidiosa infection, and by extension, with greater harvesting efficiency and economic value.

Xylella fastidiosa isolate 8.1.b obtained from a sweet orange tree affected by citrus variegated chlorosis in the state of Sao Paulo, Brazil, and shown in 1993 to be the causal agent of the disease, was cloned by repeated culture in liquid and on solid PW medium, yielding triply cloned strain 9a5c. The eighth and the 16th passages of strain 9a5c were mechanically inoculated into sweet orange plants. Presence of X. fastidiosa in sweet orange leaves of shoots having grown after inoculation (first-flush shoots) was detected by DAS-ELISA and PCR. Thirty-eight days after inoculation, 70% of the 20 inoculated plants tested positive, and all plants gave strong positive reactions 90 days after inoculation. Symptoms first appeared after 3 months and were conspicuous after 5 months. X. fastidiosa was reisolated from sweet orange leaves, 44 days after inoculation. These results indicate that X. fastidiosa strain 9a5c, derived from pathogenic isolate 8.1.b by triply cloning, is also pathogenic. Strain 9a5c is now used for the X. fastidiosa genome sequencing project undertaken on a large scale in Brazil.http://link. springer-ny.com/link/service/journals/00284/bibs/39n2p106.html
Recent studies have shown that the claim that King George III suffered from acute porphyria is seriously at fault. This article explores some of the causes of this misdiagnosis and the consequences of the misleading claims, also reporting on the nature of the king's recurrent mental illness according to computer diagnostics. In addition, techniques of cognitive archaeology are used to investigate the nature of the king's final decade of mental illness, which resulted in the appointment of the Prince of Wales as Prince Regent. The results of this analysis confirm that the king suffered from bipolar disorder type I, with a final decade of dementia, due, in part, to the neurotoxicity of his recurrent episodes of acute mania. © 2015 Royal College of Physicians.

, ao mesmo tempo que foi impedida a formação de um verdadeiro parênquima paliçádico. A grande atividade da gema apical dos cafeeiros que exibem êste tipo de variegação, tal como pode ser observada pelas freqüentes modificações na sua morfologia, conduziu essas plantas a um intenso desenvolvimento vegetativo, servindo de evidência em favor da hipótese de que distúrbios vários devem ter ocorrido durante o desenvolvimento daquelas fôlhas.Two different types of leaf variegation in coffee plants are studied on the anatomical viewpoint, and their histological differences are described, when compared with normal, green leaves. In the first case, variegated leaves are normal in shape and texture, and show different variegation patterns, being histologically identical with green leaves of normal plants. The variegation seems to be due to disturbances in the chlorophyll-producing mechanism, resulting in the formation of large, green and normal chloroplasts, aad small, yellowish and abnormal chloroplasts. The distribution at random of cells having one of these two kinds of chloroplasts can be accounted for the different variegation patterns observed. In the second example, the variegation pattern is uniform throughout the entire plant, and is a more complex phenomenon, since besides being variegated the leaves present several malformations. The anatomical study has revealed that, in this case, the chloroplasts are always normal, the variegation being rather due to the presence of an 1-3-layered hialine hypodermis, which occurs right beneath the upper epidermis. The malformations, represented by abnormalities in the shape and texture of the leaf blade, are mainly due to the lackness of a true palisade parenchyma. This tissue shows all grades of disorganization in the various portions of the leaf, being sometimes present as small patches or palisade cells or lacking completely in other instances. It is suggested that disturbances of any kind should have occurred

A locus is described in Drosophila melanogaster that modifies the expression of the white eye color gene. This trans-acting modifier reduces the expression of the white gene in the eye, but elevates the expression in other adult tissues. Because of the eye phenotype in which the expression of white is lessened but not eliminated, the newly described locus is called the Weakener of white (Wow). Northern analysis reveals that Wow can exert an inverse or direct modifying effect depending upon the developmental stage. Two related genes, brown and scarlet, that are coordinately expressed with white, are also affected by Wow. In addition, Wow modulates the steady state RNA level of the retrotransposon, copia. When tested with a white promoter-Alcohol dehydrogenase reporter. Wow confers the modifying effect to the reporter, suggesting a requirement of the white regulatory sequences for mediating the response. In addition to being a dosage sensitive regulator of white, brown, scarlet and copia, Wow acts as a suppressor of position effect variegation. There are many dosage sensitive suppressors of position effect variegation and many dosage-sensitive modifiers of gene expression. The Wow mutations provide evidence for an overlap between the two types of modifiers.

, citrus variegated chlorosis (CVC), was observed in 1987 in the Triangulo Mineiro of Minas Gerais State and the northern and north-eastern parts of SSP. By 2000, the disease affected already 34% of the 200 million sweet orange trees in SSP. By 2005, the percentage had increased to 43%, and CVC was present in all citrus growing regions of Brazil. Electron microscopy showed that xylem-limited bacteria were present in all symptomatic sweet orange leaves and fruit tissues tested, but not in similar materials from healthy, symptomless trees. Bacteria were consistently cultured from twigs of CVC-affected sweet orange trees but not from twigs of healthy trees. Serological analyses showed the CVC bacterium to be a strain of Xylella fastidiosa. The disease could be reproduced and Koch's postulates fulfilled, by mechanically inoculating a pure culture of X. fastidiosa isolate 8.1.b into sweet orange seedlings. The genome of a CVC strain of X. fastidiosa was sequenced in SSP in the frame of a project supported by FAPESP and Fundecitrus. X. fastidiosa is the first plant pathogenic bacterium, the genome of which has been sequenced. Until recently, America was free of huanglongbing (HLB), but in March 2004 and August 2005, symptoms of the disease were recognized, respectively in the State of São Paulo (SSP) and in Florida, USA. HLB was known in China since 1870 and in South Africa since 1928. Because of its destructiveness and its rapid spread by efficient psyllid insect-vectors, HLB is probably the most serious citrus disease. HLB is caused by a phloem sieve tube-restricted Gram negative bacterium, not yet available in culture. In the 1990s, the bacterium was characterized by molecular techniques as a member of the alpha proteobacteria designated Candidatus Liberibacter africanus for the disease in Africa, and Candidatus Liberibacter asiaticus for HLB in Asia. In SSP, Ca. L. asiaticus is also present, but most of the trees are infected with a new species, Candidatus Liberibacter

The xylem-limited, Gram-negative, fastidious plant bacterium Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC), a destructive disease affecting approximately half of the citrus plantations in the State of São Paulo, Brazil. The disease was recently found in Central America and is threatening the multi-billion U.S. citrus industry. Many strains of X. fastidiosa are pathogens or endophytes in various plants growing in the U.S., and some strains cross infect several host plants. In this study, a TaqMan-based assay targeting the 16S rDNA signature region was developed for the identification of X. fastidiosa at the species level. Another TaqMan-based assay was developed for the specific identification of the CVC strains. Both new assays have been systematically validated in comparison with the primer/probe sets from four previously published assays on one platform and under similar PCR conditions, and shown to be superior. The species specific assay detected all X. fastidiosa strains and did not amplify any other citrus pathogen or endophyte tested. The CVC-specific assay detected all CVC strains but did not amplify any non-CVC X. fastidiosa nor any other citrus pathogen or endophyte evaluated. Both sets were multiplexed with a reliable internal control assay targeting host plant DNA, and their diagnostic specificity and sensitivity remained unchanged. This internal control provides quality assurance for DNA extraction, performance of PCR reagents, platforms and operators. The limit of detection for both assays was equivalent to 2 to 10 cells of X. fastidiosa per reaction for field citrus samples. Petioles and midribs of symptomatic leaves of sweet orange harbored the highest populations of X. fastidiosa, providing the best materials for detection of the pathogen. These new species specific assay will be invaluable for molecular identification of X. fastidiosa at the species level, and the CVC specific assay will be very powerful for the

A study to investigate circadian variation in metabolites (lipids, protein, glucose, K+, Ca2+, Mg2+, Cl− concentrations and enzymes (lipase, amylase, proteinase, α-glucosidase activities in the femoral and thoracic muscles of adult Z. variegatus was carried out by collecting samples at 06:00, 12:00, 18:00 and 24:00 hrs GMT. The four enzymes were present throughout the day in both thoracic and femoral muscles but at varying levels. Significantly (p<0.05 higher enzymes activities were measured during the day (between 06:00 and 18:00 hours GMT (except proteinase than at night (24:00 hrs. Organic substances in the two tissues were present in significantly higher concentrations during the day than at night. Similarly, significantly more inorganic substances were recorded in the afternoon (12:00-18:00 hrs than at night in both femoral and thoracic muscles. It can thus be concluded that locomotor activities in Z. variegatus reach a peak during the day.

After the Enmasse' Coolant Channel Replacement (EMCCR) of both the reactors of Madras Atomic Power Station (MAPS), they have put up a good performance, as far as core integrity is considered. This is a tale-tell signature of the high quality of the fuel bundles manufactured by Nuclear Fuel Complex (NFC), Hyderabad. Both the reactor cores have been loaded with various types of fuel bundles viz. Natural Uranium (NU), Depleted Uranium (DU), and Deeply Depleted Uranium (DDU) and were operated at different power level with different flux configuration at different stages of operation. Even around 1026 low burn up bundle (<2500 MWD/TeU) were transferred from MAPS-1 to MAPS-2, first time in the history of PHWRS. During all such variegated operations, the Primary Heat Transport (PHT) system 131 I activity, which is synonymous with the core integrity, was maintaining low for most of the reactor operation period. However, recently a low burn up fuel bundle failure has been observed in MAPS-1. Even though the overall failure rate is very low, the cause of such failure needs to be ascertained for taking appropriate action to maintain the high standards of quality in the manufacturing process of the fuel bundles.

Full Text Available Dilobopterus costalimai (Young and Oncometopia facialis (Signoret are two of the most important species of citrus leafhoppers, vectors of bacterium Xylella fastidiosa which causes the Citrus Variegated Chlorosis (CVC disease. To develop a rearing technique for these species under laboratory conditions, the egg laying preference and nymph development were studied in different breeding systems: Rangpur lime (Citrus limonia and "falso boldo" (Vernonia condensata as host plants. Trials were set up in a randomized block design with three treatments (n=8. Females of D. costalimai had particular preference for ovipositing on Rangpur lime leaves while O. facialis females placed a higher number of eggs on "falso boldo", but it did not differ statistically from the Rangpur lime. The nymphal viability of D. costalimai was null in Rangpur lime and 58% in "falso boldo". For O. facialis the nymphal viability was 25 and 78% in Rangpur lime and "falso boldo", respectively. "Falso boldo" is more suitable as a host plant to rear the two species of citrus leafhoppers. The alternation of host plants seems to be an important survival mechanism of the CVC-vector species, as shown in natural conditions.
Full Text Available In an effort to contribute to the discussion concerning the age of rocks of the Moldanubian Variegated Group, we have undertaken Re-Os dating of molybdenite of banded carbonatite-like marbles (CLM from the graphite mine Václav at Bližná (Southern Bohemia, which belong to the metamorphic sequence of this group. The Re-Os model ages for the molybdenites range between 493 and 497 Ma and apparently correspond to the early stages of metamorphism connected with pre-Variscan rift-related tectono-metamorphic events, which affected and recrystallized sedimentary CLM material rich in Mo-Th-Nb-REE. The molybdenite bearing carbonatite like marbles situated in the footwall of Bližná graphite mine have been interpreted as carbonates with a large share of volcano-detritic material derived from contemporaneous primitive alkaline (carbonatite-like volcanism deposited in a shallow marine lagoonal environment. There is no geological evidence for the participation of fluids mobilized from host rocks in the formation of the CLM. Because the Re-Os chronometer in molybdenite is demonstrably stable through later Variscan facies metamorphism, the molybdenite chronometer has not been affected by subsequent thermal overprints associated with the Variscan orogeny.

Induced mutagenesis has played a major role in the development of many new flower color/shape mutant varieties in ornamentals. The main bottleneck with vegetatively propagated plants is that the mutation appears as a chimera whether developed through bud sport or through induced mutation. The size of the mutant sector varies from a narrow streak on a petal to the entire flower and from a portion of a branch to the entire branch. When a portion of a branch or entire branch is mutated, the mutant tissue can be isolated; on the other hand, a small sector of a mutated branch or flower cannot be isolated using the available conventional propagation techniques. A novel technique has been standardized in our laboratory for the management of chimeric tissues through direct shoot regeneration from chrysanthemum florets. 'Kasturba Gandhi', a large white flowered chrysanthemum, developed few chimeric yellow florets due to spontaneous mutation. Using in vitro protocol new yellow florets were established in pure form. In vitro mutagenesis experiments were conducted treating ray florets of chrysanthemum cultivars using gamma rays. Induced chimeric yellow, white, light yellow, light mauve and dark mauve floret color sectors and chlorophyll variegation in leaves of cv. 'Maghi' (with mauve floret and green leaves) have been established in pure form. Gamma ray induced sectorial yellow florets of cv. 'Lilith' (white floret) and yellow ray florets in both the cvs. 'Purnima' (with white florets) and 'Colchi Bahar' (with red florets) have been isolated in pure form through in vitro management. Induced sectorial flower color/shape mutations in cvs. 'Puja', 'Lalima', 'Flirt', 'Maghi' and 'Sunil' have been isolated in pure form through in vitro culture. Gamma radiation procedure and tissue culture techniques have been optimized to regenerate plants from stem internodes, stem node, shoot tip and ray florets. Present technique has opened a new way for isolating new flower color

The essential JIL-1 histone H3S10 kinase is a key regulator of chromatin structure that functions to maintain euchromatic domains while counteracting heterochromatization and gene silencing. In the absence of the JIL-1 kinase, two of the major heterochromatin markers H3K9me2 and HP1a spread in tandem to ectopic locations on the chromosome arms. Here we address the role of the third major heterochromatin component, the zinc-finger protein Su(var)3-7. We show that the lethality but not the chromosome morphology defects associated with the null JIL-1 phenotype to a large degree can be rescued by reducing the dose of the Su(var)3-7 gene and that Su(var)3-7 and JIL-1 loss-of-function mutations have an antagonistic and counterbalancing effect on position-effect variegation (PEV). Furthermore, we show that in the absence of JIL-1 kinase activity, Su(var)3-7 gets redistributed and upregulated on the chromosome arms. Reducing the dose of the Su(var)3-7 gene dramatically decreases this redistribution; however, the spreading of H3K9me2 to the chromosome arms was unaffected, strongly indicating that ectopic Su(var)3-9 activity is not a direct cause of lethality. These observations suggest a model where Su(var)3-7 functions as an effector downstream of Su(var)3-9 and H3K9 dimethylation in heterochromatic spreading and gene silencing that is normally counteracted by JIL-1 kinase activity.

The aim of the project launched jointly by DGMK and 5 companies from the German oil- and gas industry and two institutes for drilling technologies was to find suitable ways in which the drilling progress in formations with bad drilling conditions in Northern Germany, i.e. lower and middle variegated sandstone and Keuper can be increases in order to bring costs down. The borehole sunk in Northern Germany were surveyed and inventorised. Data were subjected to a thorough statistical analysis in order to obtain optimal drilling parameters and improve the drilling tools. Basic studies on rock damaging were also to be included in order to better understand the processes. Finally, the project aims at realising the optimal drilling parameters, increase drilling progress, use improved drilling machinery and thus cut costs. (orig.) [Deutsch] Ziel des DGMK-Gemeinschaftsprojektes mit 5 Firmen der deutschen Erdoel- und Erdgasindustrie sowie 2 bohrtechnischen Instituten war es, durch geeignete Massnahmen den Bohrfortschritt in schlechtbohrbaren Formationen in Norddeutschland, naemlich unterer und mittlerer Buntsandstein sowie Keuper, zu erhoehen und damit einen Beitrag zur Kostensenkung zu leisten. Um dieses Ziel zu erreichen, sollte eine Bestandsaufnahme der in Norddeutschland abgeteuften Bohrungen erfolgen. Die Daten sollten einer eingehenden statistischen Auswertung unterzogen werden. Hieraus sollten optimale Bohrparameter und Verbesserungen der Bohrwerkzeuge abgeleitet werden. Ferner sollten grundlegende Untersuchungen zur Gesteinszerstoerung herangezogen werden, um ein besseres Verstaendnis fuer die ablaufenden Prozesse zu bekommen. Durch die Realisierung optimaler Bohrparameter und den Einsatz verbesserter Bohrwerkszeuge sollte schliesslich die Erhoehung des Bohrfortschritts und damit eine Senkung der Kosten erreicht werden.

Enhanced reliability and accuracy for field deployable bioforensic detection and discrimination of Xylella fastidiosa subsp. pauca, causal agent of citrus variegated chlorosis using razor ex technology and TaqMan quantitative PCR.
Ouyang, Ping; Arif, Mohammad; Fletcher, Jacqueline; Melcher, Ulrich; Ochoa Corona, Francisco Manuel
A reliable, accurate and rapid multigene-based assay combining real time quantitative PCR (qPCR) and a Razor Ex BioDetection System (Razor Ex) was validated for detection of Xylella fastidiosa subsp. pauca (Xfp, a xylem-limited bacterium that causes citrus variegated chlorosis [CVC]). CVC, which is exotic to the United States, has spread through South and Central America and could significantly impact U.S. citrus if it arrives. A method for early, accurate and sensitive detection of Xfp in plant tissues is needed by plant health officials for inspection of products from quarantined locations, and by extension specialists for detection, identification and management of disease outbreaks and reservoir hosts. Two sets of specific PCR primers and probes, targeting Xfp genes for fimbrillin and the periplasmic iron-binding protein were designed. A third pair of primers targeting the conserved cobalamin synthesis protein gene was designed to detect all possible X. fastidiosa (Xf) strains. All three primer sets detected as little as 1 fg of plasmid DNA carrying X. fastidiosa target sequences and genomic DNA of Xfp at as little as 1 - 10 fg. The use of Razor Ex facilitates a rapid (about 30 min) in-field assay capability for detection of all Xf strains, and for specific detection of Xfp. Combined use of three primer sets targeting different genes increased the assay accuracy and broadened the range of detection. To our knowledge, this is the first report of a field-deployable rapid and reliable bioforensic detection and discrimination method for a bacterial phytopathogen based on multigene targets.

The many types of pulmonary hypertension (PH) are so protean in their biological origin, histological expression, and natural history that it is difficult to create a summary picture of the disease, or to easily compare and contrast characteristics of one type of PH with another. For newcomers to the field, however, such a picture would facilitate a broad understanding of PH. In this paper, we suggest that four characteristics are fundamental to describing the nature of various types of PH, and that taken together they define a number of patterns of PH expression. These characteristics are histopathology, developmental origin, associated clinical conditions, and potential for resolution. The “snapshot” is a way to concisely display the ways that these signal characteristics intersect in select specific types of PH, and is an effort to summarize these patterns in a way that facilitates a “big picture” comprehension of this disease.

An estimated 20 - 40% of cancer patients will develop brain metastases that are the most common intracranial tumors in adults. Patients with cerebral metastases represent a variegate group where selection of the most appropriate treatment depends on many patient- and disease-related factors. The impact of therapeutic option on overall survival is lacking and it is important to consider quality of life (QOL) when treating patients with brain metastases. A considerable proportion of patients are treated with palliative approaches such as whole-brain radiotherapy. The role of chemotherapy was limited in the past. Recently, several chemotherapeutic agents have been identified as potentially useful. This article examines the pharmacokinetics, efficacy and safety and tolerability of fotemustine (FTM) for the management of patients with cerebral metastasis from melanoma and non-small cell lung cancer (NSCLC). FTM is a third-generation nitrosourea that has proved its efficacy on brain metastases of melanoma and showed promising results for the treatment of brain metastasis of NSCLC because of its ability to pass the blood-brain barrier.

Full Text Available Intraoperative management of a known acute intermittent porphyria patient is a challenge requiring awareness of factors, which trigger an acute crisis, clinical features of a porphyric attack, knowledge of safe pharmacologic intervention, and preparedness for reintubation and ventilatory support. The classical signs of a porphyric crisis such as pain abdomen, vomiting and neuropsychiatric symptoms are masked under general anesthesia and can be confused with postoperative pain and vomiting and postoperative cognitive dysfunction, especially for intra-abdominal surgeries. Eternal vigilance for onset of an acute crisis is imperative. After a crisis of acute intermittent porphyria, residual paresis may persist for years in the absence of further attacks.

The highest component was 11-octadecenoic acid methyl ester followed by 1,12-tridecadiene. Since behavioural bioassays were not carried out, the consideration of these compounds to be pheromone semiochemicals remains a hypothesis.
Full Text Available It is well known that citrus plants that have been infected by Xylella fastidiosa display nutritional deficiencies, probably caused by production of extracellular polymers by the bacteria that block normal nutrient flow through the xylem. The aim of this work was to study the mineral composition of specific foliar areas in different stages of infection in citrus. Thus, the concentrations of macro and micronutrients in leaves of citrus infected by X. fastidiosa were measured. Samples from four infected citrus orchards in the State of São Paulo, Brazil, were respectively collected from Santa Rita do Passa Quatro, Neves Paulista, Gavião Peixoto and Paraíso counties. The presence of X. fastidiosa in leaves was confirmed by polymerase chain reaction (PCR using specific PCR primers. To understand the variation in leaf-nutrient content in citrus plants, we used foliar nutrient values from control (non-symptomatic plants as a reference. Chemometric analysis showed that the deficiency of P and K in symptomatic trees for all orchards and high concentrations of Fe, Mn and Zn were observed in chlorotic areas, although other studies revealed deficiency of zinc in leaves. This is the first report showing that a correlation between chlorotic citrus leaf and higher concentrations of Fe, Mn and Zn are observed when infected and healthy plants were compared.

Full Text Available Since Cendrars recognizes the protean nature of his personal and public self, it is not surprising that the persona of his poetry escapes easy definition. My essay studies the consequences of this fact on the relationship between the poetic persona and his reader. Seduction, set against a Freudian and transactional-analysis conceptual background, provides a methodological metaphor for my analysis. In the same way that for Freud the real event of seduction only becomes psychologically effective as a fantasy and eventually as a structural pattern for the male-female relationship, our use of the seduction metaphor takes an initial naïve event between persona and reader and transforms it into a characteristic structural relationship. The persona's initial demand of intimacy from the reader is seen to be but one position in a narrative pattern which alternates the persona's attitude vis-a-vis his own narration between intimacy and detachment (or irony. The reader's role in connection with the persona is finally not one of sympathy but one of collaboration in inflecting a reading of the persona's narrated presence. Cendrars's manipulation of the persona-reader relationship is thus a primary component of his literary appeal.

Describing the morphologic features of the thoracic pedicle in patients with adolescent idiopathic scoliosis is necessary for placement of pedicle screws. Previous studies showed inadequate reliability owing to small sample size and heterogeneity of the patients surveyed. To use CT scans (1) to describe the morphologic features of 2718 thoracic pedicles from 60 female patients with Lenke Type 1 adolescent idiopathic scoliosis and 60 age-, sex-, and height-matched controls; and (2) to classify the pedicles in three types based on pedicle width and analyze the distribution of each type. A total of 2718 pedicles from 60 female patients with Lenke Type 1 adolescent idiopathic scoliosis and 60 matched female controls were analyzed via CT. All patients surveyed were diagnosed with adolescent idiopathic scoliosis, Lenke Type 1, at the First Affiliated Hospital of Sun Yat-sen University, and all underwent pedicle screw fixation between January 2008 and December 2013 with preoperative radiographs and CT images on file. We routinely obtained CT scans before these procedures; all patients who underwent surgery during that period had CT scans, and all were available for analysis here. Control subjects had CT scans for other clinical indications and had no abnormal findings of the spine. The control subjects were chosen to match patients in terms of age (15 ± 2.6 years versus 15 ± 2.6 years) and sex. Height of the two groups also was matched (154 ± 9 cm versus 155 ± 10 cm; mean difference, -1.06 cm; 95% CI, -1.24 to -0.81 cm; p adolescent idiopathic scoliosis (22%; 293 of 1322) compared with controls (13%; 178 of 1396) (odds ratio [OR] = 0.51; 95% CI, 0.42-0.63; p adolescent idiopathic scoliosis, they commonly occurred on the concave side 34% (228 of 661) and on the AV-SC region (32%; 43 of 136).

Calcifications of the costal cartilages occur, as a rule, not until the age of 30 years. The knowledge of the clinical significance of early and extensive calcifications is still incomplete. Materials and Methods. A search was made to find patients below the age of 30 years who showed distinct calcifications of their lower costal cartilages by viewing 360 random samples of intravenous pyelograms and abdominal plain films. The histories, and clinical and laboratory findings of these patients were analyzed. Results. Nineteen patients fulfilled the criteria of premature calcifications of costal cartilages (CCCs). The patients had in common that they were frequently referred to a hospital and were treated by several medical disciplines. Nevertheless many complaints of the patients remained unsolved. Premature CCCs were often associated with rare endocrine disorders, inborn errors of metabolism, and abnormal hematologic findings. Among the metabolic disorders there were 2 proven porphyrias and 7 patients with a suspected porphyria but with inconclusive laboratory findings. Conclusion. Premature CCCs are unlikely to be a normal variant in skeletal radiology. The findings in this small group of patients call for more intensive studies, especially in regard to the putative role of a porphyria

The R gene of soybean, presumably encoding a MYB transcription factor, controls seed coat color. The gene consists of multiple alleles, R (black), r-m (black spots and (or) concentric streaks on brown seed), and r (brown seed). This study was conducted to determine the structure of the MYB transcription factor gene in a near-isogenic line (NIL) having r-m allele. PCR amplification of a fragment of the candidate gene Glyma.09G235100 generated a fragment of about 1 kb in the soybean cultivar Clark, whereas a fragment of about 14 kb in addition to fragments of 1 and 1.4 kb were produced in L72-2040, a Clark 63 NIL with the r-m allele. Clark 63 is a NIL of Clark with the rxp and Rps1 alleles. A DNA fragment of 13 060 bp was inserted in the intron of Glyma.09G235100 in L72-2040. The fragment had the CACTA motif at both ends, imperfect terminal inverted repeats (TIR), inverse repetition of short sequence motifs close to the 5' and 3' ends, and a duplication of three nucleotides at the site of integration, indicating that it belongs to a CACTA-superfamily transposable element. We designated the element as Tgm11. Overall nucleotide sequence, motifs of TIR, and subterminal repeats were similar to those of Tgm1 and Tgs1, suggesting that these elements comprise a family.

General practitioner consultations with patients of non-English speaking background (NESB) account for one in 10 encounters recorded in the BEACH (Bettering the Evaluation and Care of Health) program (NESB is defined as patients who reported that their primary language spoken at home is not English). We present a descriptive comparison of consultations with NESB and English speaking patients recorded between April 2007 and March 2009. Indigenous persons were excluded from the analysis to give a clearer picture of NESB patients of non- Australian origin. Only statistically significant differences with nonoverlapping 95% confidence intervals are reported.

This article looks at how diagnostic radiographers label their patients. An ethnographic study of the workplace culture in one diagnostic imaging department was undertaken using participant observation for four months and semi-structured interviews with ten key informants. One of the key themes; the way in which radiographers label their patients, is explored in this article. It was found from the study that within the department studied the diagnostic radiographers labelled or categorised their patients based on the information that they had. This information is used to form judgements and these judgements were used to assist the radiographers in dealing with the many different people that they encountered in their work. This categorisation and labelling of the patient appears to assist the radiographer in their decision-making processes about the examination to be carried out and the patient they are to image. This is an important aspect of the role of the diagnostic radiographer. - Highlights: • I have studied the culture in one imaging department. • Radiographers label or categorise their patients. • These labels/categories are used to manage the patient. • This is an important aspect of the way in which radiographers work.

A high prevalence of hepatitis C virus infection in porphyria cutanea tarda in some populations suggests a close link between viral hepatitis and alteration of porphyrin metabolism. Moreover, there is evidence of a role of porphyrinopathies in hepatocarcinogenesis. The aim of our study was to obtain data on the prevalence and patterns of heme metabolism alterations in patients with chronic hepatitis C virus infection. Urinary porphyrin excretion was prospectively studied in 100 consecutive ou...

Pseudoporphyria is a photosensitive bullous disease, which resembles porphyria cutanea tarda. Normal porphyrin levels in urine, stool and blood define pseudoporphyria. Pseudoporphyria is associated with chronic renal failure, haemodialysis, a variety of drugs (e.g. naproxen, nabumetone, furosemid......, ciprofloxacin, voriconazole, acitretin), tanning beds and UVA exposure. Treatment consists of UV protection and cessation of suspected agents. Patients in haemodialysis can benefit from treatment with N-acetylcysteine or glutathione....

Porphyria cutanea tarda, lymphoma and thyroid diseases among others can also attend a chronic infection, but the exact...... pathogenesis behind these manifestations is not clearly mapped. Antiviral treatment is reported to induce sustained virological response in more than half of the treated patients with a variable clinical response in the extrahepatic manifestations....
Full Text Available Background and Purpose: Chronic granulomatous disease (CGD is an inherited disorder of the nicotinamide adenine dinucleotide phosphate (NADPH oxidase complex. This disorder results in recurrent life-threatening bacterial and fungal infections. Aspergillus species are the most common fungal infections in these patients. Case Report: Herein, we present a case of fungal infection in a girl with CGD. We confirmed aspergillosis through the positive microscopic and macroscopic examinations, as well as radiology results. Invasive aspergillosis in this patient with pneumonia, lung abscess, and osteomyelitis of the ribs was not initially treated with amphotericin B (Am B and recombinant interferon-gamma. Conclusion: Among infectious diseases, fungal infections, in particular aspergillosis, remain a serious problem in CGD patients. Considering poor clinical response and deficient immune system, rapid diagnosis of fungal infection and optimizing the treatment of these patients are recommended.

Full Text Available Background . Complementary and alternative medicine (CAM practices for cancer have become popular among oncology patients. An increasing interest in alternative medicine can be explained by the inefficiency of conventional treatment, dissatisfaction with treating patients like objects, and the will to use all available treatment methods. Objectives . The authors assessed how often patients use CAM methods, and which of them are most popular. Material and methods . The study was conducted in Military Hospital no. 109 and the Independent Public Clinical Hospital no. 1 in Szczecin among 100 chemotherapy patients. This survey-based study was performed using an original questionnaire. Results. Most respondents (68% did not use alternative methods to fight the disease. The most popular treatment methods were: herbal medicine (50%, alternative medicine preparations (38% and diet (25%, and the least common: hypnosis (3% and aromatherapy (3%. Analyzed sociodemographic factors had no effects on a choice of a CAM method. Patients obtained information about CAM methods mainly from the Internet (40%, medical staff (37% and literature (31%. Conclusions . 1. Using CAM by patients receiving chemotherapy for neoplasms is quite a common phenomenon. 2. CAM were more often chosen by women. Neither the duration of the disease nor sociodemographic data had effects on making the decision to use CAM methods. 3. The most popular CAM were: herbal medicine, alternative medicine preparations, and diet. 4. Cancer patients should receive special support from nurses and doctors as well as other members of the therapeutic team. Oncology patients should never be left on their own so that they were forced to seek help and support in therapies unconfirmed by scientific investigation.

Full Text Available A focused and commented review on the impact of dermatologic diseases and interventions in the solidary act of donating blood is presented to dermatologists to better advise their patients. This is a review of current Brazilian technical regulations on hemotherapeutic procedures as determined by Ministerial Directive #1353/2011 by the Ministry of Health and current internal regulations of the Hemotherapy Center of Ribeirão Preto, a regional reference center in hemotherapeutic procedures. Criteria for permanent inaptitude: autoimmune diseases (>1 organ involved, personal history of cancer other than basal cell carcinoma, severe atopic dermatitis or psoriasis, pemphigus foliaceus, porphyrias, filariasis, leprosy, extra pulmonary tuberculosis or paracoccidioidomycosis, and previous use of etretinate. Drugs that impose temporary ineligibility: other systemic retinoids, systemic corticosteroids, 5-alpha-reductase inhibitors, vaccines, methotrexate, beta-blockers, minoxidil, anti-epileptic, and anti-psychotic drugs. Other conditions that impose temporary ineligibility: occupational accident with biologic material, piercing, tattoo, sexually transmitted diseases, herpes, and bacterial infections, among others. Discussion: Thalidomide is currently missing in the teratogenic drugs list. Although finasteride was previously considered a drug that imposed permanent inaptitude, according to its short halflife current restriction of 1 month is still too long. Dermatologists should be able to advise their patients about proper timing to donate blood, and discuss the impact of drug withdrawal on treatment outcomes and to respect the designated washout periods.Uma revisão centrada no impacto de doenças e intervenções dermatológicas no ato solidário de doar sangue é apresentada aos dermatologistas para melhor aconselhamento dos seus pacientes.

The main ecological peculiarities of dry bor in Ukrainian Polessye were given. Research were carried out in Central Polessie of Ukraine during 1997 - 1999. Results were obtained due to spectrometric measurement of specific activity of 137 Cs in fruit bodies of mushrooms and in the soil. Species composition of macromycetes was divided on homogeneous groups on intensity of 13 7Cs accumulation. Amanita porphyria, A. muscaria and Tricholoma portentosum belong to the group of weak 137 Cs accumulation from the soil (TF = 15 - 20); Amanita pantherina, A. phalloides, Cantharellus cibarius, Boletus edulis, Tricholoma flavovirens and Laccaria laccata - to the group of moderate radionuclide accumulation (TF = 30 - 55). The group of strong 137 Cs accumulation (TF = 100 - 180) consists of Suillus variegates, S. bovines and Hydnum imbricatum; and group of very strong accumulation (TF 200 - 280) - of Xerocomus badius, Lactarius rufus, Russula xerampelina, Cortinarius varius and Paxillus involutus. Cortinarius sanguineus (with TF 400) is an accumulator of 137 Cs. Comparative evaluation of dry bor was given from the point of view of purchase of edible macromycetes in it

Patient safety has been a highly researched topic in health care since the year 2000. One strategy for improving patient safety has been to encourage patients to take an active role in their safety during their health care experiences. However, little research has shed light on how patients view their roles. This study attempted to address this deficit by inductively exploring the results of a qualitative study in which patients reported their ideas about what they believe their roles should be. Patients with an overnight stay in the previous 90 days at one of three hospitals were surveyed using a mailing methodology. Of 1,040 respondents, 491 provided an open-ended response regarding what they believe the patient role should be. Qualitative analysis found several prominent themes. The largest proportion of responses (23%) suggested that patients should follow instructions given by care providers. Other prominent themes were that patients should ask questions and become informed about their conditions and treatments, and many implied that they should expect competent care. Our results suggest that patients believe they should be able to trust that they are being provided competent care, as opposed to assuming a leadership role in their safety. Our results suggest that engaging patients in safety efforts may be complex, requiring a variety of strategies. Managers must provide environments conducive to staff and patient interactions to support patients in this effort. Different types of patients may require different engagement strategies.

Full Text Available Here’s the thing. While I have my asthma under control and my sleeping is no worse than usual, I am still near the uaigh. That’s the word for grave in Irish, and it’s also part of the word for loneliness. I’m near one or the other, or both. There was a time when my health was the only thing I talked about, and my friends from that time ask me now, and I remember that that was the person I was; when health was a fear, because pain was my first language. But what’s really bothering me is the way I use the possessive when it comes to my asthma, my insomnia, my thinning hair, my symptoms. It makes me think I think I am these things. Am I? I wilt therefore I am? If they are me, where will I go if I lose them? I remember when I learned the word ontology – the study of the nature of being. If I am sad, is sad me? If sad is me then what happens when someone treats my sadness? If we were all speaking Irish we would say that sadness is on me. But we’re not. Because when I was five I asked where English came from and my parents introduced me to stair. If we all spoke Irish we would say stair instead of history. But we speak English, mostly, and so stair is relegated to something we use to get up or down, never a story. Did you know that I carry my people’s history in my bones? People didn’t believe me when I said that but then scientists wrote about it, and discovered what was already there — inherited in the blood, the bones, the DNA, the genomes, the chromosomes, like thinning curly hair, like weak lungs, like poetry, like insomnia — and it’s all the rage now, that codified stairstory inside us. Once when I was waiting on a trolley I kept on trying to get up even though I knew I’d fall down. So they put an orderly to mind me. Well, he was there to restrain me, but I didn’t mind. He was young and eager to be seen to be good with patients. I asked him how long his shift had been and he said it was his first. After a bit of this

Patients demand to be active participants on and partners with the health care team to design their care regimen. Patients bring unique perceptions and expectations and use these to evaluate service quality and satisfaction. If customer satisfaction is not achieved and a patient complaint results, staff must have the skills to respond and launch a service recovery program. Service recovery, when done with style and panache, can retain loyal customers. Achieving patient satisfaction and resolving patient complaints require commitment from top leadership and commitment from providers to dedicate the time to understand their patients' needs.

Preoperative teaching is an important part of patient care and can prevent complications, as well as promote patient fulfillment during hospitalization. A study was conducted at Alton Ochsner Medical Foundation in New Orleans, LA, in 1989, to determine the impact of a preoperative teaching program on the incidence of postoperative atelectasis and patient satisfaction. Results showed no significant difference of postoperative complications and patient gratification after participating in a structured preoperative teaching program. As part of this study, it was identified that a patient evaluation tool for a preoperative teaching class needed to be developed. The phases of this process are explained in the following article.

To report the personal experiences of patients undergoing awake craniotomy for brain tumor resection. We carried out a qualitative descriptive survey of patients` experiences with awake craniotomies for brain tumor resection. The survey was conducted through a standard questionnaire form after the patient was discharged from the hospital. Of the 9 patients who met the inclusion criteria and underwent awake craniotomy, 3 of those patients reported no recollection of the operation. Five patients had auditory recollections from the operation. Two-thirds (6/9) reported that they did not perceive pain. Five patients remembered the head clamp fixation, and 2 of those patients classified the pain from the clamp as moderate. None of the patients reported that the surgery was more difficult than anticipated. Awake craniotomy for surgical resection of brain tumors was well tolerated by patients. Most patients reported that they do not recall feeling pain during the operation. However, we feel that further work and exploration are needed in order to achieve better control of pain and discomfort during these types of operations.

Full Text Available Physician-patient relationship is unique in some aspects and not-so-unique in other aspects when compared to other human interactions. Until-unless for the sake of health promotional activities, this relationship is almost always conceived in the times of human sufferings and consequently culminated when those sufferings have subsided as well as sought out happiness has ensued/been achieved. However, not all physician-patient relationships follow the normal course and/or meet the natural ends. These abnormal relationships are not inconsequential in terms of numbers and/or their effects (short-term and long term on both patients and physicians. Every country has its own baggage in the wake of why, how and what about these abnormal ends to physician-patient relationships; however, the most common causes are the patients’ inability to pay their medical bills, the conflicting goals of physicians and their patients in regards to patients’ sufferings’ management and finally the behavioral issues (patients’ and/or physicians’ interfering these relationships. Irrespective of any cause, the physicians should never forget that the patient can always discharge their physicians and discontinue their relationship with their physicians without any reason (until unless the physicians deem those patients either incapable/non-consentable to do so and/or potential threat to their own personal safety or other people’s safety.

Intro: This paper discusses a central professional dilemma in patient-centred education: on one hand the concern for ensuring patients autonomy and right to make their own decisions regarding their treatment and, on the other hand, a concern for getting patients to make the “right” decisions......-centredness is thus promoted as a way to organize health more effectively (in terms of cost and treatment outcomes) and as a way to ensure patients’ autonomy and fundamental right to make their own decisions regarding their treatment. Critical voices within social and nursing theory have however argued....... The paper shows that the programme’s attempt to facilitate that patients make their “own” decision is challenged by patients who understand the preventive programme in relational terms and even demand more intervention from the professionals in terms of expert advice, involvement, and discipline.

This study aimed to describe patient-handling demands in inpatient units during a 24-hour period at a military health care facility. A 1-day total population survey described the diverse nature and impact of patient-handling tasks relative to a variety of nursing care units, patient characteristics, and transfer equipment. Productivity baselines were established based on patient dependency, physical exertion, type of transfer, and time spent performing the transfer. Descriptions of the physiological effect of transfers on staff based on patient, transfer, and staff characteristics were developed. Nursing staff response to surveys demonstrated how patient-handling demands are impacted by the staff's physical exertion and level of patient dependency. The findings of this study describe the types of transfers occurring in these inpatient units and the physical exertion and time requirements for these transfers. This description may guide selection of the most appropriate and cost-effective patient-handling equipment required for specific units and patients.

Over 25 years ago, Kubler-Ross identified anger as a predictable part of the dying process. When the dying patient becomes angry in the clinical setting, all types of communication become strained. Physicians can help the angry dying patient through this difficult time by using 10 rules of engagement. When physicians engage and empathize with these patients, they improve the patient's response to pain and they reduce patient suffering. When physicians educate patients on their normal responses to dying and enlist them in the process of family reconciliation, they can impact the end-of-life experience in a positive way.

The aim of this paper is to present our "Patient Keeper" application, which is a client-server medical application. "Patient Keeper" is designed to run on a mobile phone for the client application and on a PC for the server application using J2ME and JAVA2, respectively. This application can help doctors during visits to their patients in hospitals. The client application allows doctors to store on their mobile phones the results of their diagnoses and findings such as temperature, blood pressure, medications, analysis, etc., and send this information to the server via short message service (SMS) for storage in a database. The server can also respond to any request from the client and send the result via Bluetooth, infrared, or over the air. Experimental results showed a significant improvement of the healthcare delivery and reduction for in-patient stay.

This paper aims to investigate how patient satisfaction affects propensity to return, i.e. loyalty. Data from 678 hospitals were matched using three sources. Patient satisfaction data were obtained from Press Ganey Associates, a leading survey firm; process-based quality measures and hospital characteristics (such as ownership and teaching status) and geographic areas were obtained from the Centers for Medicare and Medicaid Services. The frequency with which end-of-life patients return to seek treatment at the same hospital was obtained from the Dartmouth Atlas. The study uses regression analysis to estimate satisfaction's effects on patient loyalty, while holding process-based quality measures and hospital and market characteristics constant. There is a statistically significant link between satisfaction and loyalty. Although satisfaction's effect overall is relatively small, contentment with certain hospitalization experience may be important. The link between satisfaction and loyalty is weaker for high-satisfaction hospitals, consistent with other studies in the marketing literature. RESEARCH LIMITATION/IMPLICATIONS: The US hospitals analyzed are not a random sample; the results are most applicable to large, non-profit teaching hospitals in competitive markets. Satisfaction ratings have business implications for healthcare providers and may be useful as a management tool for private and public purchasers. The paper is the first to show that patient satisfaction affects actual hospital choices in a large sample. Because patient satisfaction ratings are also correlated with other quality measures, the findings suggest a pathway through which individuals naturally gravitate toward higher-quality care.

Full Text Available Remote patient management (RPM offers renal health care providers and patients with end-stage kidney disease opportunities to embrace home dialysis therapies with greater confidence and the potential to obtain better clinical outcomes. Barriers and evidence required to increase adoption of RPM by the nephrology community need to be clearly defined. Ten health care providers from specialties including nephrology, cardiology, pediatrics, epidemiology, nursing, and health informatics with experience in home dialysis and the use of RPM systems gathered in Vienna, Austria to discuss opportunities for, barriers to, and system requirements of RPM as it applies to the home dialysis patient. Although improved outcomes and cost-effectiveness of RPM have been demonstrated in patients with diabetes mellitus and heart disease, only observational data on RPM have been gathered in patients on dialysis. The current review focused on RPM systems currently in use, on how RPM should be integrated into future care, and on the evidence needed for optimized implementation to improve clinical and economic outcomes. Randomized controlled trials and/or large observational studies could inform the most effective and economical use of RPM in home dialysis. These studies are needed to establish the value of existing and/or future RPM models among patients, policy makers, and health care providers.

Repair of uv-light induced DNA damage and changes in the semiconservative DNA synthesis were studied by in vitro autoradiography in the skin of patients with lightdermatoses (polymorphous light eruption, porphyria cutanea tarda, erythropoietic protoporphyria) and xeroderma pigmentosum as well as in that of healthy controls. In polymorphous light eruption the semiconservative DNA replication rate was more intensive in the area of the skin lesions and in the repeated phototest site, the excision repair synthesis appeared to be unaltered. In cutaneous prophyrias a decreased rate of the repair incorporation could be detected. Xeroderma pigmentosum was characterized by a strongly reduced repair synthesis.

With development of psycho-oncology it has been demonstrated to establish an important link between the cancer patient`s treatment as well as psycho-social support for the patient and psychiatric treatment and care for the if it is needed. With this connection between them it has been proposed to use of bio-psycho-social-model in cancer patient to improve their care. To achieve this goal, it is expected from medical personnel to realize patients psychosocial need und if he/she has a psychiatric disorders or syndromes. For the medical personnel that work in oncology services, it is inevitable to organize in order to raise the awareness of depression in the cancer patients. In the present study, it is focused on raising the awareness of depression in cancer patient for the medical personnel.

This paper examines the complex issues of measuring the patient experience and evaluating the quality of health care. It discusses the use of surveys, patient stories and narrative methods of data collection in an attempt to define quality and how it should be measured. A recent Department of Health (DH) document insists that patients will be at the heart of decision making in the NHS by having greater control in informing strategic commissioning decisions (DH 2010c). The government aims to improve patient experience, enabling patients to rate services according to the quality of care they receive. This will be carried out using information generated by patients. This paper discusses the advantages and disadvantages of using surveys in gathering patient satisfaction data. It considers the value of surveys in measuring quality of care and appraises their usefulness in strengthening patients' collective voice. The paper investigates the use of another source of feedback - it examines the design of qualitative data collection methods as a means of gaining feedback from service users in encouraging providers of health care to be more responsive to their needs. Too often, patients are expected to fit the services, rather than services meeting the patients' needs. The most effective way of exploring and representing the patient's experience is by using a mixed-method approach. In other words, an integrated approach with the use of surveys and more narrative methods, such as patient stories, will effectively define quality and how it should be measured, ensuring that the focus is always on what matters most to patients.

A practice that consistently and continuously measures patient perceptions will be more efficient and effective in its daily operations. With pay-for-performance requirements on the horizon and consumer rating sites already publicizing impressions from physician encounters, a practice needs to know how it is performing through the eyes of the patients. Azalea Orthopedics has used patient feedback to coach its physicians on better patient communication. The Orthopaedic Institute has used patient satisfaction results to reduce wait times and measure the return on investment from its marketing efforts. Patient survey results that are put to work can enhance the efficiency and effectiveness of practice operations as well as position the practice for increased profitability.

Protecting the privacy of the patient's medical record is a central issue in current discussions about a patient bill of rights, and controversy over a proposed "unique health identifier" has raised the decibel level of these discussions. At the heart of the debate is how best to resolve the inherent conflict between the individual's right to privacy and the need for access to patients' health information for reasons of public health, research, and health care management.

Full Text Available In the patient-physician encounter, physicians hone their skills while alleviating the patient’s suffering. Both benefit. Leaning on the work of Hippocrates, Darwin, and William Osler, the authors sketch out the case for honoring patients as indispensable teachers of the art and science of medicine. They argue that this tradition of Hippocratic medicine both anticipates modern precision medicine and reawakens a focus on public health medicine, each a benefit to the patients and communities served by physicians. A community that compromises the learning relationship of physician to patient and population undermines quality of care.
Full Text Available In mechanically ventilated patients, assisted mechanical ventilation (MV is employed early, following the acute phase of critical illness, in order to eliminate the detrimental effects of controlled MV, most notably the development of ventilator-induced diaphragmatic dysfunction. Nevertheless, the benefits of assisted MV are often counteracted by the development of patient-ventilator dyssynchrony. Patient-ventilator dyssynchrony occurs when either the initiation and/or termination of mechanical breath is not in time agreement with the initiation and termination of neural inspiration, respectively, or if the magnitude of mechanical assist does not respond to the patient’s respiratory demand. As patient-ventilator dyssynchrony has been associated with several adverse effects and can adversely influence patient outcome, every effort should be made to recognize and correct this occurrence at bedside. To detect patient-ventilator dyssynchronies, the physician should assess patient comfort and carefully inspect the pressure- and flow-time waveforms, available on the ventilator screen of all modern ventilators. Modern ventilators offer several modifiable settings to improve patient-ventilator interaction. New proportional modes of ventilation are also very helpful in improving patient-ventilator interaction.

National Committee for Quality Assurance recommends patient-centered medical homes incorporate input from patient populations; however, many health care organizations do not. This qualitative study used two open-ended questions from 148 active duty Army Soldiers and their family members to illicit recommendations for primary care providers and clinic leadership that would improve their health care experiences. Content analysis and descriptive statistics were used to analyze responses. Participant responses were related to four major themes: Access to Care, Interpersonal Interaction, Satisfaction of Care, and Quality of Care. Participants were overall satisfied with their care; however, spending less time waiting for appointments and to see the provider or specialist were the most frequently requested improvements related to Access to Care. For Interpersonal Interaction, 82% of the responses recommended that providers be more attentive listeners, courteous, patient, caring, and respectful. Decreasing wait times and improving interpersonal skills would improve health care experiences and patient satisfaction. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

The benefits of ionizing radiation in the diagnosis and treatment of cancer, as well as other conditions such as cardiac ablation, are well established. However determination, monitoring, and evaluation of patient doses is not as easy task. Furthermore, radiation doses for individual patients may vary greatly from one radiological procedure to another. Attention is needed to reduce unnecessary radiation exposure to patients from All types of radiation producing machines and equipment. The patient risk from radiation injury-stochastic and/or deterministic must be weighted against the benefits of a proper medical examination or treatment as well as the risk of depriving the patient from the necessary medical care. Arbitrary reduction of radiological patient doses without regard to final outcome is determined to proper medical care provided to the patient. Sacrificing image quality in order to reduce patient dose is potentially harmful to the patient as well. Furthermore, the role of radiation exposure incurred from screening procedures such as mammography, needs to be properly considered and differentiated from medically indicated procedures. A known radiation induced risk needs to be balanced against diagnostic efficacy of a screening procedure. In these cases, regulations on standards and guidelines for determination, monitoring, and evaluation of patient doses may be appropriate. In this paper, the technical data collected in the United States have been compared with the corresponding data in Canada. However, even here, it has been recognized that we can not assume that one dose limit fits all. It is advisable to consider individual patient specifics if it means the difference between detection and miss

The objectives of this study were to determine the entrance surface dose to the patient and to estimate the dose to the uterus and ovaries due to hysterosalpingography (HSG) diagnostic examinations performed in Recife-Pe, Brazil. The entrance doses were measured using four thermoluminescent dosimeters per patient, attached to anatomical landmarks on the patient's skin. The study was carried out on 25 patients between 21 and 45 years of age who underwent the HSG examinations in two training hospitals and one private radiodiagnostic institute. The number of exposures performed ranged from 4 to 15 radiographs per patient measured. Entrance surface doses varied between 4.99 and 36.6 mGy, with an average of 12.6mGy. The doses to the ovaries and uterus ranged from 0.80 mGy to 5.8 mGy and 1.10mGy to 8.05 mGy, respectively. (author)

Physiotherapy of cancer patients is one of the most controversial issues in our country. Malignant diseases are firstly mentioned as a contraindication of physiotherapy. Until now, physiotherapy was not suggested (or only in limited accessibility) for those patients who had malignant disease in medical history. International medical practice was less restrictive in managing this topic. The development of imaging techniques put this question in a new light. On the basis of evidence, the majority of articles have reported beneficial effects of physiotherapy in cancer patients, and only few articles mentioned it as harmful. Of course, each patient requires an individual assessment, however, if we exclude the possibility of tumor recurrence and metastasis, most of physiotherapy procedures can be used safely. One of the aims of this review is to support the physicians' decisions when to prescribe treatments, in such a way, that more patients could receive physiotherapy. Orv.

For nearly 20 years, thermoluminescent dosemeters (TLDs) have been used by NRPB to investigate the doses received by patients undergoing diagnostic examinations with x-rays, and these measurements have formed the basis for national recommendations on patient protection. Monitoring typical levels of patient dose should represent an essential element of routine quality assurance in x-ray departments. In order to promote more widespread measurements in hospitals, NRPB has drawn on a wealth of experience to establish a high-quality service providing TLDs for medical dosimetry by post. (author)

Patient exposures arising from radiological procedures form the largest part of the population exposure from artificial sources of radiation. According to United Nations Scientific Committee on the Effects of Atomic Radiation, the annual frequency of X ray examinations is 360 per 1000 individuals worldwide. Owing to the associated risk of radiation detriment to the patient, there is a clear need to monitor and control these exposures, and to optimize the design and use of the X ray imaging equipment so that the patient dose is reduced as far as possible, consistent with achieving the required clinical image quality.

The purpose of this paper is to examine how strategic, patient-centred communication plays a part in the discursive management of expectations posed to patients and healthcare organizations. The paper provides an analysis of four documents collected as part of an ethnographic case study regarding "The Perspective of the Patient" - a Danish Hospital's patient-centred communication programme. Mapping methods inspired by Grounded Theory are used to qualify the analysis. The paper shows that strategic patient-centred communication addresses both a care-oriented approach to the patient and deploys market perceptions of patients. Market and care is seen as co-existing organizing modes that entail expectations to the patient. In the communication programme the patient is constructed in six information-seeking patient figures: affective patient; target group patient; citizen with rights; patient as a competent resource; user as active partner; and consumer. As a result, the patient-centred communication programme renders the patient as a flexible figure able to fit organizational demands of both care orientation and market concerns. This study contributes to qualitative research in organizational health communication by combining two subfields - patient-centredness and health communication - in an empirical study of how market and care are intertwined in a patient-centred communication programme. The argument goes beyond the prevalent prescriptive approaches to patient-centredness and healthcare communication, instead providing a critical analytical perspective on strategic communication and patient-centredness and showing how expectations are posed to both patient and organization.

Devices have been described for positioning a patient's upper and lower thorax. This invention provides reproducible positioning for a female patient's breasts, for example in planning treatment of and treating breast tumours. The patient is placed prone, using for example an upper thorax device. A support device is placed central to and beneath her breasts to partially displace them outwards. The device may be triangular in section with one apex contacting the chest wall at the sternum. Restraining straps may be provided to hold the breasts against the support device. Means may be provided to take a healthy breast from the path of radiation through the tumour. (author)

Gillon outlines some prima facie moral duties of physicians to patients that have emerged from his previous articles in a series on philosophical medical ethics. These duties follow from four general ethical principles--respect for autonomy, beneficence, non-maleficence, and justice--plus the self-imposed supererogatory duty of medical beneficence. From these principles the author derives such duties as providing adequate information and advice on treatment options, encouraging patient participation leading to informed decisions, maintaining competence and exposing incompetence, admitting errors, disclosing personal medico-moral standards, and acknowledging that other interests may occasionally supersede those of the individual patient. Gillon concludes that, where self interest conflicts with medical beneficence, the claim of medicine as a profession requires that the patient's interests take priority.

To measure the frequency of depression and its risk factors in patients under going hemodialysis. It is a cross-sectional prospective study conducted at Hemodialysis unit of Shalamar Hospital and Shaikh Zayed Hospital, Lahore from 1/sup st/ January 2006 to 30/sup th/ April 2006. All patients getting regular hemodialysis for more than three months were included. Beck's Depression Inventory- II (BDI-II; adapted in Urdu) was administered on all the patients who were able to read or understand it. Blood sample were drawn at the same time for routine hematological, biochemical parameters and viral markers (Anti HCV and HbsAg). Diagnosis was made as per Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM IV) for correlation of psychological variables with clinical, hematological and biochemical parameters. Eighty nine patients were enrolled which included fifty two (58.4%) were male and seventy seven (86.5%) were married. Major causes of renal failure were diabetes, hypertension and chronic glomerulonephrotis. Duration of dialysis was from 03 to 49 months with mean of 19.64 +- 11.7 months. Severity of depression was categorized in to mild, moderate and severe on the basis of BDI score. Majority of the patients fifty (56.1%) were moderately to severely depressed and there was no gender difference in the prevalence of depression. Majority of patients undergoing hemodialysis were depressed. Major risk factors for depression were marital status, illiteracy, number of children, socioeconomic factors, gender, hypertension and hypoalbuminemia. Patients with anemia, hyponatremia and hyperkalemia had suicidal tendency. Patients with hepatitis C and disturbed liver function have strong correlation with psychological parameters. (author)

This study aims to investigate the simultaneous effect of subjective norm, perceived behavioral control and trust on patient loyalty. The empirical data were collected through survey. The respondents of the survey are 157 patients of a health-care service institution in Bogor, Indonesia. Multiple regressions analysis was performed to test the conceptual model and the proposed hypotheses. The findings showed that subjective norm and trust influence patient loyalty positively. However, this research also found that perceived behavioral control does not influence patient loyalty significantly. The survey was only conducted at one health-care service institution in Bogor, Indonesia. In addition, convenience sampling method was used. These conditions may cause that the research results can not be generalized to the other contexts. Therefore, replication research is needed to test the stability of the findings in the other contexts. Health-care service institutions need to pay attention to trust and subjective norm to establish patient loyalty. This study is believed to be the first to develop and test patient loyalty model that includes subjective norm, perceived behavioral control and trust.

PURPOSE We aimed to develop a simple standardized clinical score to stratify emergency ward patients with clinically suspected PE into groups with a high, intermediate, or low probability of PE, in order to improve and simplify the diagnostic approach. METHODS Analysis of a database of 1090 consecutive patients admitted to the emergency ward for suspected PE, in whom diagnosis of PE was ruled in or out by a standard diagnostic algorithm. Logistic regression was used to predict clinical parameters associated with PE. RESULTS 296 out of 1090 patients (27%) were found to have PE. The optimal estimate of clinical probability was based on eight variables: recent surgery, previous thromboembolic event, older age, hypocapnia, hypoxemia, tachycardia, band atelectasis or elevation of a hemidiaphragm on chest X-ray. A probability score was calculated by adding points assigned to these variables. A cut-off score of 4 best identified patients with low probability of PE. 486 patients (49%) had a low clinical probability of PE (score 9). CONCLUSION This clinical score, based on easily available and objective variables, provides a standardized assessment of the clinical probability of PE. Applying this score to emergency ward patients suspected of PE could allow a more efficient diagnostic process.

To investigate the baseline status of patients' awareness, knowledge, and attitudes to patient safety in China, and to determine the factors that influence patients' involvement in patient safety. We conducted a cross sectional survey using questionnaires adapted from recent studies on patient safety from outside China. The items included medical errors, infection, medication safety, and other aspects of patient safety. The questionnaire included 17 items and 5 domains. The survey was conducted between Jan. 2009 and Dec. 2010 involving 1000 patients from ten grade-A hospitals in seven provinces or cities in China. Most patients from the surgery departments completed the questionnaires voluntarily and anonymously. Five reviewers independently input the data into Microsoft Excel 2003, and the data were double-checked. Data were analyzed using SPSS 15.0 software for differences in the perceptions and attitudes of patients toward patient safety among different genders, ages, and regions. We distributed 1000 questionnaires and collected 959 completed questionnaires (response rate: 96%). Among the respondents, 58% of patients did not know what medical error is. Sixty-five percent of patients wanted disclosure of all medical errors. After errors occurred, 58% of patients wanted explanations of all possible harms that had resulted. Among 187 patients who had experienced medical errors, 83% of patients had sought appropriate legal action. About 52% of patients understood hospital infection, but 28% patients did not know that infections could occur in hospital. Seventy-eight percent of patients thought that medical staff should wash their hands before examining patients. More than half of the patients (68%) were willing to remind the staff of hygiene if they saw unsanitary conditions in a health clinic. Only 14% of patients knew the side effects of medications that they took. The majority of patients surveyed expressed willingness to contribute to patient safety, but their
In a context of regular review of transfusion practice, the aim of this review is to present an update of the scientific basis of the so-called "patient blood management" (PBM), the state of its development in Europe, and possible ways to progress its development further in France. Analysis and synthesis of the data from scientific literature on the scientific basis of PBM (methods, indications, efficacy, risks, efficiency). PBM appears as an evidence-based, patient centred, multidisciplinary approach, aiming to optimise the care of patients who might need transfusion and, consequently, the use of blood products. PBM is based on three pillars: optimise the patient's own blood supplies, minimise blood loss, optimise patient's tolerance of anaemia. Available scientific evidence can be considered as sufficient to consider PBM guidelines and practices as an indispensable complement to the transfusion medicine guidelines and practices. Several countries have launched PBM programmes (alternatives to allogeneic transfusion and optimisation of the use of blood components). Although current French national transfusion guidelines contain some PBM measures, PBM programmes should be further developed in France, primarily for medical reasons. Possible ways, using the existing basis having proved to be effective, are proposed to further develop PBM in France, as a complement to transfusion medicine, with the participation of involved stakeholders, including experts from relevant medical specialties, both at local and national levels.

To elicit patient stakeholders' experience and perspectives about patient-centred care. Qualitative. A large urban healthcare system. Four patient stakeholders who are prostate cancer survivors. Experience and perspectives of patient stakeholders regarding patient-centred care and treatment decisions. Our patient stakeholders represented a diverse socio-demographic group. The patient stakeholders identified engagement and dialogue with physicians as crucial elements of patient-centred care model. The degree of patient-centred care was observed to be dependent on the situations. High severity conditions warranted a higher level of patient involvement, compared to mild conditions. They agreed that patient-centred care should not mean that patients can demand inappropriate treatments. An important attribute of patient-centred outcomes research model is the involvement of stakeholders. However, we have limited knowledge about the experience of patient stakeholders in patient-centred outcomes research. Our study indicates that patient stakeholders offer a unique perspective as researchers and policy-makers aim to precisely define patient-centred research and care.

Aim To evaluate patient satisfaction with the cataract surgery service and identify any areas for improvement, determination of patient satisfaction with referral, out-patient consultation, pre-assessment clinic, surgery and post-operative care, also to report patients' comments relating to improvement in service provision. Methodology A retrospective study was undertaken for 150 patients underwent cataract surgery at Barrow General Hospital, UK, the survey sample was by postal questionnaires. We collected our data from the theatre lists for a period of 4 month. Results This study included 150 patients; the response rate was (72% 108 patients, Most patients were referred from their general practitioner 86.1%, 93 (86.1% patients were happy with the time interval from seeing their GP to eye clinic. In the eye out patient department many factors significantly affected the level of patient satisfaction, in general the more information provided for the patient the more the satisfaction. Conclusion Patient satisfaction is on important health outcome old understanding both the domains of satisfaction as well as their relative importance to patients is necessary to improve the overall quality of patient care. Meeting the doctor, presenting all relevant information and giving printed information are very important factors in improving the patient's satisfaction with cataract surgery.
Full Text Available Humanoids have increasingly become the focus of attention in robotics research in recent years, especially in service and personal assistance robotics. This paper presents the application developed for humanoid robots in the therapy of dementia patients as a cognitive stimulation tool. The behaviour of the robot during the therapy sessions is visually programmed in a session script that allows music to play, physical movements (dancing, exercises, etc., speech synthesis and interaction with the human monitor. The application includes the control software on board the robot and some tools like the visual script generator or a monitor to supervise the robot behaviour during the sessions. The robot application's impact on the patient's health has been studied. Experiments with real patients have been performed in collaboration with a centre of research in neurodegenerative diseases. Initial results show a slight or mild improvement in neuropsychiatric symptoms over other traditional therapy methods.

The risk associated with receiving health care has called for an increased focus on the role of patients in helping to improve safety. Recent research has highlighted that patient involvement in patient safety practices may be influenced by patient perceptions of patient safety practices and the perceptions of their health care providers. The objective of this research was to describe patient involvement in patient safety practices by exploring patient and nursing staff perceptions of safety. Qualitative focus groups were conducted with a convenience sample of nursing staff and patients who had previously completed a patient safety survey in 2 tertiary hospital sites in Eastern Canada. Six focus groups (June 2011 to January 2012) were conducted and analyzed using inductive thematic analysis. Four themes were identified: (1) wanting control, (2) feeling connected, (3) encountering roadblocks, and (4) sharing responsibility for safety. Both patient and nursing staff participants highlighted the importance of building a personal connection as a precursor to ensuring that patients are involved in their care and safety. However, perceptions of provider stress and nursing staff workload often reduced the ability of the nursing staff and patient participants to connect with one another and promote involvement. Current strategies aimed at increasing patient awareness of patient safety may not be enough. The findings suggest that providing the context for interaction to occur between nursing staff and patients as well as targeted interventions aimed at increasing patient control may be needed to ensure patient involvement in patient safety.

In many developing countries, teleophthalmology is being utilized to provide quality eye care to the underserved urban population and the unserved remote rural population. Over the years, technological innovations have led to improvement in evidence and teleophthalmology has evolved from a research tool to a clinical tool. The majority of the current teleophthalmology services concentrate on patient screening and appropriate referral to experts. Specialty care using teleophthalmology services for the pediatric group includes screening as well as providing timely care for retinopathy of prematurity (ROP. Among geriatric eye diseases, specialty teleophthalmology care is focused toward screening and referral for diabetic retinopathy (DR, glaucoma, age-related macular degeneration (ARMD, and other sight-threatening conditions. Comprehensive vision screening and refractive error services are generally covered as part of most of the teleophthalmology methods. Over the past decades, outcome assessment of health care system includes patients’ assessments on their health, care, and services they receive. Outcomes, by and large, remain the ultimate validators of the effectiveness and quality of medical care. Teleophthalmology produces the same desired clinical outcome as the traditional system. Remote portals allow specialists to provide care over a larger region, thereby improving health outcomes and increasing accessibility of specialty care to a larger population. A high satisfaction level and acceptance is reported in the majority of the studies because of increased accessibility and reduced traveling cost and time

A patient support system for use in computerized tomography (CT) is described. The system is particularly useful for CT scanning of the brain and also of the abdominal area. The support system consists of two moveable tables which may be translated into position for X-ray scanning of the patient's body and which may be translated incrementally and automatically to obtain scans at adjacent locations. For use with brain scans, the second table is replaced by a detachable restraint assembly which is described in detail. The support system is so designed that only a small volume of low density material will intercept the X-ray beam. (UK)

Full Text Available Background. Diabetes mellitus (DM confers high vascular risk and is a growing national epidemic. We assessed clinical characteristics and prevalence of diagnosed DM among patients hospitalized with acute myocardial infarction (AMI in the US over the last decade. Methods. Data were obtained from all states within the US that contributed to the Nationwide Inpatient Sample. All patients admitted to hospitals between 1997 and 2006 with a primary discharge diagnosis of AMI were included. Time trends in the proportion of these patients with DM diagnosis were computed. Results. The portion of patients with comorbid diabetes among AMI hospitalizations increased substantially from 18% in 1997 to 30% in 2006 (<.0001. Absolute numbers of AMI hospitalizations in the US decreased 8% (from 729, 412 to 672, 243, while absolute numbers of AMI hospitalizations with coexisting DM rose 51% ((131, 189 to 198, 044, both (<.0001. Women with AMI were significantly more likely to have DM than similarly aged men, but these differences diminished with increasing age. Conclusion. Although overall hospitalizations for AMI in the US diminished over the last decade, prevalence of diabetes rose substantially. This may have important consequences for the future societal vascular disease burden.

Schizophrenia is a maldevelopmental disorder of the brain that manifests in positive, negative, cognitive and affective symptoms. Currently, the mainstay of treatment involves pharmacotherapy. The limitations of antipsychotic treatment are that they can only control symptoms and cannot cure the illness, and 20% of patients do not respond, thus leading to the requirement of maintenance treatment. Patients that do respond continue to have disabling residual symptoms such as amotivation and isolation, maladaptive behavior, and impaired social functioning. These symptoms prevent patients from attaining educational, occupational, and social roles. Psychosocial interventions and models of quality of life in schizophrenia are based on the notion that increases in psychosocial functioning will be related to improvement in subjective experiences, such as self-esteem and satisfaction with life. The comparative effect of specific treatment methods and the additional benefits of multiple treatments need to be explored. Diversified techniques have also been employed, such as shaping, cognitive process therapy, mastery-oriented skill training, motivation and enhancement. Issues in designing psychosocial interventions and the role of various professionals in providing such interventions need to be carefully considered. Predictor variables and the indications for particular therapies in an individual need to be explored. Generalizability of the gains made by rehabilitation/recovery is also an important consideration. Patients in jail, chronic mental hospitals, private facilities, and the Veterans Administration system are all different in their ability to benefit, their motivations, and the severity of their psychopathology. Therefore, it is very difficult to generalize findings from one setting to another.

If the "old economy" preached standardization of products/services in order to reduce costs, the "new economy" is based on the recognition of the needs and the management of information. It is aimed at providing better and more usable services. One scenario is a national health service with regional management but based on competition between hospitals/companies.This led to a different handling of the user/patient, which has become the center of the health system: marketing seeks to retain the patient, trying to push a client-patient to not change their healthcare service provider. In costs terms, it is more economical to retain a customer rather than acquire a new one: a satisfied customer is also the best sounding board for each company. Customer equity is the management of relations with patients which can result in a greater customer value: it is possible to recognize an equity of the value, of the brand and of the report. Loyalty uses various marketing activities (basic, responsive, responsible, proactive and collaborative): each hospital/company chooses different actions depending on how many resources it plans to invest in loyalty.

Full Text Available Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL is a hereditary neurological disease accompanied by recurrent ischemic events, characterized by the presence of psychiatric disorders. The aim of this study was to examine the occurrence of depression and its severity among patients with CADASIL. Sixteen patients with diffuse white matter changes on MRI and clinical signs suggesting CADASIL were included in the study. Definitive diagnosis of CADASIL was obtained by electron microscopic analysis of skin biopsies. Testing of the patients’ affective status was primarily devoted to detecting depression. Electron microscopic examinations of all skin biopsies revealed numerous granular osmiophilic material (GOM deposits embedded into the basal lamina around altered or degenerated vascular smooth muscle cells (VSMCs. Clinical symptoms of depression were present in a great number of examined CADASIL patients. The frequency of depression was higher than previously reported. Psychiatric disturbances might also represent the onset of CADASIL, especially in young patients, and should be evaluated by differential diagnosis.

Individuals have different values. They seek to express their individuality even when receiving medical care. It is a part of modern medical practice and respect for patient autonomy to show respect for different values. We give an account of what it means to respect different values and challenging patients in medical practice. Challenging choices are often choices which are perceived by many to be either irrational or against a person's interests, such as engaging in harmful or excessively risky activities. When the medical profession is involved in such choices, the basic medical principle of acting in a person's best interests is challenged. Often doctors refuse to respect controversial choices on paternalistic grounds. We should all respect and facilitate the controversial choices of competent individuals, subject to resource limitations, our own and others well-being and autonomy, and the public interest. But more importantly, sometimes such choices make for a better, more autonomous life. Sometimes, such choices reflect considerations of global well-being or altruism, or idiosyncratic attitudes to risk. Sometimes, they reflect unusual values. However, in some other cases, controversial choices are irrational and are not expressions of our autonomy. Doctors should assist patients to make rational if individual choices. The patient also bears the responsibility for bringing his beliefs to the attention of the clinician.

PURPOSE Complementary and Alternative Medicine (CAM) can be defined as medical practices not taught widely at US medical schools or generally available at US hospitals. National studies suggest that between 30–40% of the general US population use CAM. These users tend to be more educated, have higher incomes, and are more likely to be between the ages of 30–49. However, to date, no study has documented the use of CAM among the homebound population, patients who are usually elderly, debilitated, and have less access to medical care. We studied the use of alternative therapies in homebound patients of the Mount Sinai Visiting Doctors Program serving the inner city of New York. METHODS Eligibility for the study was limited to patients who are in the Visiting Doctors Program, and whose mini-mental status exam score was greater than 20 or who were deemed competent to complete the survey by their primary care provider. Participant's CAM use was assessed by a survey administered by an interviewer at the patient's home. RESULTS Forty-nine consecutive, eligible patients were interviewed and a survey completed. Among the respondents, 84% were women, the mean age was 78.6 (STD = 14.1). Respondents were 51% Caucasian, 27% African-American, 14% Hispanic and 8% other. On rating their own health, 69% rated it as poor to fair, 22% rated it as good, and 8% rated it as very good to excellent. Sixty-nine percent of the respondents reported using one or more CAM in the past 12 months. Commonly used CAM included: vitamins/minerals (33%) [excluding MVI, calcium], spiritual healing (27%), and herbal remedies (20%). Spiritual healing included prayer and faith healing. The most common herbal remedies were garlic, ginger, and chamomile tea. Among CAM users, their main sources of information about CAM came from their own physicians (32%), family/friends/co-workers (18%), and newspaper/radio/TV (18%). CONCLUSION The use of CAM in this elderly, debilitated, homebound population was

Patient safety advisory disseminated to patients at the study hospitals. Attitudes towards and experiences with the advisory. Hcw support for the intervention and patients' intentions to apply the recommendations were modelled using regression analyses. Patients (95%) and hcw (78%) agreed that hospitals should educate patients how to prevent errors. Hcw and patients' evaluations of the safety advisory were positive and followed a similar pattern. Patients' intentions to engage in safety were significantly predicted by behavioral control, subjective norms, attitudes, safety behaviors during hospitalization and experiences with taking action. Hcw support for the campaign was predicted by rating of the advisory (Odds ratio (OR) 3.4, confidence interval (CI) 1.8-6.1, Ppatients (OR 1.9, CI 1.1-3.3, P= 0.034) and experience of unpleasant situations (OR 0.6, CI 0.4-1.0, P= 0.035). The safety advisory was well accepted by patients and hcw. To be successful, the advisory should be accompanied by measures that target norms and barriers in patients, and support staff in dealing with difficult situations.

Objective Psychotherapy is a common non-pharmacological approach to help cancer patients in their psychological distress. The benefit of psychotherapies was documented, but the types of psychotherapies proposed are varied. Given that the previous literature review was a decade ago and no quantitative analysis was done on this topic, we again critically and systematically reviewed all published trials on psychotherapy in cancer patients. Method We identified 17 clinical trials on six types of psychotherapy for cancer patients by searching PubMed and EMBASE. Result There were four trials involved adjunct psychological therapy which were included in quantitative analysis. Each trial demonstrated that psychotherapy improved the quality of life and coping in cancer patients. There was also a reduction in distress, anxiety, and depression after a psychological intervention. However, the number and quality of clinical trials for each type of psychotherapy were poor. The meta-analysis of the four trials involved adjunct psychological therapy showed no significant change in depression, with only significant short-term improvement in anxiety but not up to a year-the standardized mean differences were -0.37 (95% confidence interval (CI) = -0.57, -0.16) at 2 months, -0.21 (95% CI = -0.42, -0.01) at 4 months, and 0.03 (95 % CI = -0.19, 0.24) at 12 months. Conclusion The evidence on the efficacy of psychotherapy in cancer patients is unsatisfactory. There is a need for more rigorous and well-designed clinical trials on this topic.

Increased patient involvement is a goal in contemporary health care, and of importance to the development of patient oriented ICT. In this paper we discuss how the design of patient-user interfaces can affect patient involvement. Our discussion is based on 12 semi-structured interviews with patient users of a web-based solution for patient--doctor communication piloted in Norway. We argue ICT solutions offering a choice of user interfaces on the patient side are preferable to ensure individual accommodation and a high degree of patient involvement. When introducing web-based tools for patient--health professional communication a free-text option should be provided to the patient users.

Light-emitting diodes (LEDs) are penetrating into the huge market of general lighting because they are energy saving and environmentally friendly. The big advantage of LED light sources, compared to traditional incandescent lamps and fluorescent light tubes, is the flexible spectral design to make white light using different color mixing schemes. The spectral design flexibility of white LED light sources will promote them for novel applications to improve the life quality of human beings. As an initial exploration to make use of the spectral design flexibility, we present an example: 'no blue' white LED light source for sufferers of disease Porphyria. An LED light source prototype, made of high brightness commercial LEDs applying an optical filter, was tested by a patient suffering from Porphyria. Preliminary results have shown that the sufferer could withstand the light source for much longer time than the standard light source. At last future perspectives on spectral design flexibility of LED light sources improving human being's life will be discussed, with focus on the light and health. The good health is ensured by the spectrum optimized so that vital hormones (melatonin and serotonin) are produced during times when they support human daily rhythm.

Electronic patient portals give patients access to personal medical data, potentially creating opportunities to improve knowledge, self-efficacy, and engagement in healthcare. The combination of knowledge, self-efficacy, and engagement has been termed activation. Our objective was to assess the relationship between patient activation and outpatient use of a patient portal. Survey. A telephone survey was conducted with 180 patients who had been given access to a portal, 113 of whom used it and 67 of whom did not. The validated patient activation measure (PAM) was administered along with questions about demographics and behaviors. Portal users were no different from nonusers in patient activation. Portal users did have higher education level and more frequent Internet use, and were more likely to have precisely 2 prescription medications than to have more or fewer. Patients who chose to use an electronic patient portal were not more highly activated than nonusers, although they were more educated and more likely to be Internet users.

Full Text Available Mucorales species are deadly opportunistic fungi with a rapidly invasive nature. A rare disease, mucormycosis is most commonly reported in patients with diabetes mellitus, because the favorable carbohydrate-rich environment allows the Mucorales fungi to flourish, especially in the setting of ketoacidosis. However, case reports over the past 20 years show that a growing number of cases of mucormycosis are occurring during treatment following bone marrow transplants (BMT and hematological malignancies (HM such as leukemia and lymphoma. This is due to the prolonged treatment of these patients with steroids and immunosuppressive agents. Liposomal amphotericin B treatment and posaconazole are two pharmacologic agents that seem to be effective against mucormycosis, but the inherently rapid onset and course of the disease, in conjunction with the difficulty in correctly identifying it, hinder prompt institution of appropriate antifungal therapy. This review of the literature discusses the clinical presentation, diagnosis, and treatment of mucormycosis among the BMT and HM populations.

Well-characterized symptoms such as exertional dyspnea and fatigue have a negative impact on patients’ quality of life (QoL and restrict physical activity in daily life. The impact of COPD symptoms on QoL is often underestimated; for example, 36% of patients who describe their symptoms as being mild-to-moderate also admit to being too breathless to leave the house. Additionally, early morning and nighttime symptoms are a particular problem. Methods are available to allow clinicians to accurately assess COPD symptoms, including patient questionnaires. Integrated approaches to COPD management, particularly pulmonary rehabilitation, are effective strategies for addressing symptoms, improving exercise capacity and, potentially, also increasing physical activity. Inhaled bronchodilators continue to be the mainstay of drug therapy in COPD, where options can be tailored to meet patients’ needs with careful selection of the inhaled medication and the device used for its delivery. Overall, an integrated approach to disease management should be considered for improving QoL and subsequent patient outcomes in COPD.

Sport activity is an important issue in many patients with a pacemaker either because they performed sport activities before pacemaker implantation to reduce the cardiovascular risk or to improve the course of an underlying cardiovascular disease (e.g. coronary artery disease, heart failure) by sports. Compared to patients with an implantable cardioverter defibrillator (ICD) the risks from underlying cardiovascular disease (e.g. ischemia, heart failure), arrhythmia, lead dysfunction or inappropriate therapy are less important or absent. Sport is contraindicated in dyspnea at rest, acute heart failure, new complex arrhythmia, acute myocarditis and acute myocardial infarction, valvular disease with indications for intervention and surgery and comorbidities which prevent physical activity. Patients with underlying cardiovascular disease (including hypertension) should preferably perform types and levels of physical activity that are aerobic (with dynamic exercise) such as running, swimming, cycling instead of sport with high anaerobic demands and high muscular workload. In heart failure, studies demonstrated advantages of isometric sport that increases the amount of muscle, thereby preventing cardiac cachexia. Sport with a risk of blows to the chest or physical contact (e.g. boxing, rugby, martial arts) should be avoided. Implantation, programming and follow-up should respect specific precautions to allow optimal physical activity with a pacemaker including implantation of bipolar leads on the side contralateral to the dominant hand, individual programming of the upper sensor and tracking rate and regular exercise testing.

This study was undertaken to consider the psychological aspect of diabetes with regard to improving clinical outcomes. The review was limited to literature reports on the causes, solutions, and treatments of some common psychological problems known to complicate diabetes management. A literature search was undertaken using Pub-Med, CINAHL, Proquest, Elsevier, Blackwell Synergy, Ovid, Ebsco, Rose net, and Google websites, including studies published in English journals between 1995 and 2006. Therefore about 88 articles were selected based on the inclusion criteria. In earlier studies, relatively little empirical research was found to substantiate the effect of psychological counseling in complicated diabetes. The greatest deficits were seen in areas of mental health, self-esteem parent impact, and family cohesion. There were some different factors, which influence the psychological aspect of diabetic patients, such as age, gender, place of living, familial and social support, motivation, energy, life satisfaction, and lifestyle. There are various types of solutions for coping with the psychological problems in diabetic clients. The most essential solution lies in educating the patients and healthcare providers on the subject. Before initiating each educational intervention, a thorough assessment would be crucial. Treatment plans may benefit from cognitive behavior therapy (CBT), behavior family therapy, improving family communication, problem-solving skills, and providing motivation for diabetic patients. Moreover, it seems that the close collaboration between diabetologists and psychologists would be fruitful.

For patient-oriented mobile health tools to contribute meaningfully to improving healthcare delivery, widespread acceptance and use of such tools by patients are critical. However, little is known about patients' attitudes toward using health technology and their willingness to share health data with providers. To investigate primary care patients' comfort sharing health information through mobile devices, and patients' awareness and use of patient portals. Patients (n=918) who visited one of 6 primary care clinics in the Northwest US completed a survey about health technology use, medical conditions, and demographics. More patients were comfortable sharing mobile health information with providers than having third parties store their information (62% vs 30%, Somers D=.33, phigher among patients with a chronic condition (AOR= 3.18, p=0.004). Comfort, awareness, and use of health technologies were variable. Practices introducing patient-facing health technologies should promote awareness, address concerns about data security, and provide education and training, especially to older adults and those with health literacy limitations. Patient-facing health technologies provide an opportunity for delivering scalable health education and self-management support, particularly for patients with chronic conditions who are already using patient portals.

The expectations of patient are one of the determining factors of healthcare service. The purpose of this study is to measure the Patients' Expectations, based on Patient's Rights. This study was done with Likert-Survey in Trabzon population. The analyses showed that the level of the expectations of the patient was high on the factor of receiving information and at an acceptable level on the other factors. Statistical meaningfulness was determined between age, sex, education, health insurance, and the income of the family and the expectations of the patients (pstudy, the current legal regulations have higher standards than the expectations of the patients. The reason that the satisfaction of the patients high level is interpreted due to the fact that the level of the expectation is low. It is suggested that the educational and public awareness studies on the patients' rights must be done in order to increase the expectations of the patients.

This study analyzed the contact preferences of newly diagnosed cancer patients and healthy control group participants. In line with the theory of socioemotional selectivity, patients were more likely than control participants to prefer contact with familiar social partners, but this difference was stronger in younger and middle-aged patients than in older patients. Across a 6-month interval, patients' contact preferences changed according to the perceived success of therapy. For example, if therapy was perceived to be successful, patients showed an increasing interest in contacts with unfamiliar social partners. Results indicate that contact preferences are adapted to the perception of limited versus extended future lifetime. Copyright (c) 2006 APA, all rights reserved.

Full Text Available Ushma Shah, David T Wong, Jean Wong Department of Anesthesia, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, Canada Abstract: Most surgeries in North America are performed on an ambulatory basis, reducing health care costs and increasing patient comfort. Patient satisfaction is an important outcome indicator of the quality of health care services incorporated by the American Society of Anesthesiologists (ASA. Patient satisfaction is a complex concept that is influenced by multiple factors. A patient's viewpoint and knowledge plays an influential role in patient satisfaction with ambulatory surgery. Medical optimization and psychological preparation of the patient plays a pivotal role in the success of ambulatory surgery. Postoperative pain, nausea, and vomiting are the most important symptoms for the patient and can be addressed by multimodal drug regimens. Shared decision making, patient–provider relationship, communication, and continuity of care form the main pillars of patient satisfaction. Various psychometrically developed instruments are available to measure patient satisfaction, such as the Iowa Satisfaction with Anesthesia Scale and Evaluation du Vecu de I'Anesthesie Generale, but none have been developed specifically for ambulatory surgery. The ASA has made recommendations for data collection for patient satisfaction surveys and emphasized the importance of reporting the data to the Anesthesia Quality Institute. Future research is warranted to develop a validated tool to measure patient satisfaction in ambulatory surgery. Keywords: patient, satisfaction, anesthesia, outcomes, questionnaire, perspectives

Heartburn, the main symptom of gastrooesophageal reflux disease (GORD), might be expected to occur infrequently in achalasia, a disorder characterised by a hypertensive lower oesophageal sphincter (LOS) that fails to relax. Nevertheless, it is often described by patients with achalasia. The medical records of 32 patients with untreated achalasia who complained of heartburn, and of 35 similar patients who denied the symptom, were reviewed to explore the implications of heartburn in this condition. Data on endoscopic and manometric findings, and on the onset and duration of oesophageal symptoms were collected. Three patterns of heartburn were observed: (1) in 8 patients (25%) the onset of heartburn followed the onset of dysphagia, (2) in 15 patients (47%) heartburn preceded the onset of dysphagia and persisted as dysphagia progressed, and (3) in 9 patients (28%), heartburn preceded the onset of dysphagia and stopped as dysphagia progressed. The mean (SD) basal LOS pressure in the patients with heartburn (38 (16) mm Hg) was significantly lower than that in patients without the symptom (52 (26) mm Hg); the lowest LOS pressure (29 (11) mm Hg) was observed in the subset of patients whose heartburn preceded the onset of dysphagia and then stopped. It is concluded that patients who have achalasia with heartburn have lower basal LOS pressures than patients who have achalasia without this symptom. In some patients with achalasia, the appearance of dysphagia is heralded by the disappearance of longstanding heartburn. For these patients, it is speculated that achalasia develops in the setting of underlying GORD. PMID:7590421

The aim of this study was to elicit patient safety experts' views of patient participation in promoting patient safety. Data were collected between September and December in 2014 via an electronic semi-structured questionnaire and interviews with Finnish patient safety experts (n = 21), then analysed using inductive content analysis. Patient safety experts regarded patients as having a crucial role in promoting patient safety. They generally deemed the level of patient safety as 'acceptable' in their organizations, but reported that patient participation in their own safety varied, and did not always meet national standards. Management of patient safety incidents differed between organizations. Experts also suggested that patient safety training should be increased in both basic and continuing education programmes for healthcare professionals. Patient participation in patient safety is still lacking in clinical practice and systematic actions are needed to create a safety culture in which patients are seen as equal partners in the promotion of high-quality and safe care. © 2016 John Wiley & Sons Australia, Ltd.

Self-mutilation, the deliberate destruction or alteration of body tissue without conscious suicidal intent, occurs in a variety of psychiatric disorders. Major self-mutilation includes eye enucleation and amputation of limbs or genitals. Minor self-mutilation includes self-cutting and self-hitting. The author examines patients' explanations for self-mutilation which frequently focus on religions or sexual themes, and discusses scientific explanations that draw on biological, psychological, social, and cultural theories. Although no one approach adequately solves the riddle of such behaviors, habitual self-mutilation may best be thought of as a purposeful, if morbid, act of self-help.
What does patient autonomy mean? If an autonomous choice is defined as an objective and rational choice, is the doctor's prescription not always the best route? Our contemporary democracies are marked by moral and religious pluralism which obliges society to respect a multiplicity of choices of existence. Three levels are important in terms of autonomy: a range of intellectual capacities, freedom with regard to constraints (external and internal), the capacity to be in control of one's existence.

A retrospective analysis of 29 patients with septic bursitis was undertaken to ascertain if immunocompromised patients differed in their clinical presentations, type of organisms cultured, and outcome when compared with their non-immunocompromised cohorts. Thirty episodes of septic bursitis occurred in 29 patients, 43 percent of which occurred in immunocompromised patients. Despite similar clinical presentations, the bursae of immunocompromised patients took three times longer to sterilize and had a much higher bursal white blood cell count when compared with the bursae of non-immunocompromised patients. The bacteriologic spectrum was essentially identical in both groups; there were no cases in which gram-negative organisms were recovered from infected bursae. No cases of septic bursitis were seen in neutropenic patients. The most common factors contributing to an immunocompromised state were alcoholism or steroid therapy. A successful resolution of septic bursitis was seen in all the patients in the immunocompromised groups.

Health literacy has been described as the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions. Improving health literacy may serve to promote concordance with therapy, engage patients in their own health care, and improve health outcomes. Patient portal technology aims at enabling patients and families to have easy access to key information in their own medical records and to communicate with their health care providers electronically. However, there is a gap in our understanding of how portals will improve patient outcome. The authors believe patient portal technology presents an opportunity to improve patient concordance with prescribed therapy, if adequate support is provided to equip patients (and family/carers) with the knowledge needed to utilise the health information available via the portals. Research is needed to understand what a health consumer will use patient portals for and how to support a user to realise the technology's potential.

Consumerism in health care defines patients as self-determined, rational customers. Yet, it is questionable whether vulnerable patients, such as the terminally ill, also fulfill these criteria. Vulnerable contexts and the patient's perspective on being a customer remain relatively unexplored. The present study addresses this research gap by analyzing terminally ill patients' views on being customers. To explore the ways in which patients in palliative care refer to themselves as patients/customers, and how the patients' concepts of self-determination are related to their attitudes toward the patient/customer role. Qualitative interviews were conducted. Data were analyzed in three steps: narrative analysis, thematic content analysis, and typology construction. Researchers recruited 25 patients via the Department of Palliative Care, University Medical Center Freiburg, Germany. In many ways, palliative patients contradict the image of a self-determined customer. The palliative patient role is characterized by the concept of relational self-determination rather than an unrestricted self-determination. Self-attribution as a customer still occurs when positively associated with a person-centered, individualized treatment. Thus, the customer and patient role overlap within the palliative care setting because of the focus on the individual. The idealized customer role cannot be arbitrarily applied to all medical fields. Palliative patients are dependent on the physician, regardless of whether the customer or patient role is preferred. Hence, self-determination must be understood in relational terms, and physicians must recognize their crucial role in promoting patients' self-determination in the context of shared decision-making.

Latinos comprise nearly 16 percent of the U.S. population, and this proportion is anticipated to increase to 30 percent by 2050. Latinos are a diverse ethnic group that includes many different cultures, races, and nationalities. Barriers to care have resulted in striking disparities in quality of health care for these patients. These barriers include language, lack of insurance, different cultural beliefs, and in some cases, illegal immigration status, mistrust, and illiteracy. The National Standards for Culturally and Linguistically Appropriate Services address these concerns with recommendations for culturally competent care, language services, and organizational support. Latinos have disproportionately higher rates of obesity and diabetes mellitus. Other health problems include stress, neurocysticercosis, and tuberculosis. It is important to explore the use of alternative therapies and belief in traditional folk illnesses, recognizing that health beliefs are dependent on education, socioeconomic status, and degree of acculturation. Many-but not all-folk and herbal treatments can be safely accommodated with conventional therapy. Physicians must be sensitive to Latino cultural values of simpatia (kindness), personalismo (relationship), respeto (respect), and modestia (modesty). The LEARN technique can facilitate cross-cultural interviews. Some cultural barriers may be overcome by using the "teach back" technique to ensure that directions are correctly understood and by creating a welcoming health care environment for Latino patients.

Materials and methods: 200 patients with primary obesity were studied: 83 men and 117 women at age from 18 to 61 years old, median age 41,5 years [31,0; 50,0]; body weight 107 kg [94; 128,5], waist circumference 112 cm [102; 124]; neck circumference 41 cm [38; 46], body mass index (BMI 36,9 [32,8; 42,3]. Results: We found an association between sleep duration, chronotype and the emotional eating. Significant sleep reduction (to less than 6 hours was associated with high level of anxiety, depression, emotional eating and insomnia. Younger age, early onset and shorter duration of obesity and brisk weight gain during last is connected to the evening chronotype. The emotional eating associated with hypersomnolence in the absence of statistically significant increase of anxiety and depression in individuals with evening chronotype. Sleep duration and chronotype have no significant effect on the body weight, metabolic, hormonal parameters and the dynamics of body. weight after 7±1 months of treatment of obesity.

The purpose of this study is to evaluate whether damage to the hypothalamus due to craniopharyngioma or consequent surgery may involve the sleep-wake regulatory system, resulting in sleep disturbances and sleepiness. Seven craniopharyngioma patients and 10 healthy controls were evaluated with sleep questionnaires including the Epworth Sleepiness Scale, polysomnography, and a multiple sleep latency test (MSLT). Five patients and eight controls had lumbar puncture performed to determine hypocretin-1 levels. Patients tended to feel sleepier than control individuals of the same age (p = 0.09). No subjects had symptoms of hypnagogic hallucinations, sleep paralyses, or cataplexies. Four patients and one control had periodic leg movements (PLMs). One patient had fragmented sleep pattern, rapid eye movement (REM) sleep without atonia, and PLMs. One patient had short sleep periods during the daytime. Four patients had fragmented sleep pattern. With the MSLT, four patients and two controls had mean sleep latency of < 8 min. One patient and three controls had sudden onset of REM sleep in 2/5 and 3/5 sleep periods, respectively. All subjects showed normal hypocretin-1 levels. Four patients had electrophysiological findings indicative of central hypersomnia including one patient meeting the criteria of narcolepsy. The sleep-wake regulatory system may be involved in craniopharyngioma patients.

Patients are becoming increasingly active in their relationship with medical professionals. Their relationship with medical students needing to learn clinical skills, may be specially problematic if patients are not willing to accept their involvement in the medical team. To examine patient's perceptions of their relation with medical students and their agreement to let students be part of the treating team. Qualitative study using taped semi-structured interviews addressed to inpatients from one public and one private hospital in Chile. Both groups of patients acknowledged that students dedicated more time to them, but they expressed their preference to limit student's participation to clinical history taking and physical examination. They also expected them to be observers rather than actors. Patients from the private hospital emphasized that only one student per instructor should participate in their care. Patients from the public hospital were more compliant about student's participation. The right to refuse students' involvement in their care was clearly known by all patients from the private system and by most patients from the public hospital. Patients in Chilean public and private hospitals were in general positive regarding student's participation in their care. Students' clinical practice ought to strictly respect patients's rights, and patients should be considered volunteers who generously agree to cooperate with the education of medical students.
It is a central argument in the growing Danish PRO-arena, that a large-scale collection of PRO from patients in the Danish Healthcare system will pave the way for more genuine patient involvement in clinical decision-making, quality management and governance of the health services. In this paper I...... discuss how patient involvement is being (re)configured when increasingly connected to national visions of participatory healthcare. A central discussion centers on ‘meaningful use’ of patient-generated data promoting patients’ expectations and experiences as a criterion for how to proceed...... with the national use of PRO. But how do assumptions of what constitutes meaning for patients interact with the kinds of roles that patients are expected to take on with PROtools? What forms of participation are assumed to be meaningful and thus good and which are not? In sketching emerging versions of patient...

Patient recall of treatment information is a key variable towards chronic disease (CD) management. It is unclear what communication and patient participation characteristics predict recall. To assess what aspects of doctor-patient communication predict patient recall of medication information. To describe lifestyle treatment recall, in CD primary care patients. Observational study within a RCT. Community-based primary care (PC) practices. Family physicians (n=18): practicing >5 years, with a CD patient caseload. Patients (n=159): >40 years old, English speaking, computer literate, off-target hypertension, type II diabetes and/or dyslipidaemia. Patient characteristics: age, education, number of CDs. Information characteristics: length of encounter, medication status, medication class. Communication variables: socio-emotional utterances, physician dominance and communication control scores and PACE (ask, check and express) utterances, measured by RIAS. Number of medication themes, dialogue and initiative measured by MEDICODE. Recall of CD, lifestyle treatment and medication information. Frequency of lifestyle discussions varied by topic. Patients recalled 43% (alcohol), 52% (diet) to 70% (exercise) of discussions. Two and a half of six possible medication themes were broached per medication discussion. Less than one was recalled. Discussing more themes, greater dialogue and patient initiative were significant predictors of improved medication information recall. Critical treatment information is infrequently exchanged. Active patient engagement and explicit conversations about medications are associated with improved treatment information recall in off-target CD patients followed in PC. Providers cannot take for granted that long-term off-target CD patients recall information. They need to encourage patient participation to improve recall of treatment information. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

Full Text Available Everyone has the right to equal treatment irrespective of color, culture, origin or religion. Jewish patients obey many rules. The use of proper diet, adherence to the principles of purity, prayer, performing rituals is very important for them. Medical staff is committed to providing patients with safety, regardless of the differences. Understanding the most important values, ethics and practices of Judaism will help to provide professional care for the patient of Jewish faith. Appropriate communication, understanding and tolerance are essential for creating a relationship with the patient, through which it will be possible to achieve the desired therapeutic effect and improve the quality of life of patients.

This paper assesses the use of a patient stretcher that directly docks to a CT scanner for acutely injured and/or critically ill patients. The stretcher permits performance of radiography and acts as a platform for critical care monitoring and patient support devices. During a 1-year period, the prototype CT-docking stretcher was used for 35 patients sustaining acute trauma and 25 patients from critical care units. Observations were elicited from physicians, nurses and technologists concerning the advantages or disadvantages of the docking stretcher. Advantages of the CT-docking stretcher included time saved in moving patients to the CT table from the admitting/emergency ward, transfer of critically ill patients onto the stretcher in the controlled environment of the intensive care unit rather than the CT suite, increasing CT throughput by direct docking of the patient stretcher to the CT scanner rather than manual transfer of complex support and monitoring devices with the patient, decreased risk associated with physical movement of patients with potentially unstable spinal injuries or unstable physiologic status, and decrease in potential for injury to medical personnel performing patient transfer
The objective of this project was to review patient dosimetry aiming at reducing the patient dose during diagnostic procedures while maintaining the best image quality in order to protect patients from ionizing radiation. CT examination was selected in this study to represent imaging protocols with high patient doses used in diagnostic radiology. Dosimetric parameters in CT which are CTDI, CTDIW, DLP, MSAD, organ dose and effective dose were discussed. Parameters such as tube current, tube voltage, filtration, scan volume and slice thickness were found to affect patient dose, therefore proper management of these factors was recommended. For optimization of protection of the patient, application of the “as low as reasonably achievable” (ALARA) principle was recommended as an important key for avoiding overexposure and minimizing patient doses. Also it was recommended that CT examinations should be performed if and only if is the only suitable option when weighed against other options which do not involve ionizing radiation exposure.

I argue that the distinction which is current in much writing on medical ethics between autonomous and non-autonomous patients cannot cope comfortably with weak-willed (incontinent) patients. I describe a case involving a patient who refuses a blood transfusion even though he or she agrees that it would be in his or her best interests. The case is discussed in the light of the treatment of autonomy by B Brody and R Gillon. These writers appear to force us to treat an incontinent patient either as autonomous, just like a rational agent whose decisions are in accordance with his beliefs or as non-autonomous, like comatose patients or children. Though neither is entirely satisfactory I opt for describing such patients as autonomous but point out that in cases like this the principle of respect for autonomy does not give a determinate answer about how the patient ought to be treated.

This study reviews our experience with laparoscopic cholecystectomy in the treatment of cholelithiasis in transplant patients. Demographic data, medications used, and operative and postoperative data of all transplant recipients who were subjected to laparoscopic cholecystectomy for cholelithiasis at our hospital were obtained. A total of 15 transplant patients (13 renal transplantation and 2 bone marrow transplantation) underwent laparoscopic cholecystectomy. All patients were admitted to the hospital on the day of the operation. The immunosuppressive regimen was not modified during hospitalization. Clinical presentation of cholelithiasis was biliary colicky (n=12), acute cholecystitis (n=2), and jaundice (n=1). The operation was uneventful in all patients. Postoperative complications were nausea and vomiting in 2 patients, prolonged tracheal intubation in 1, wound infection in 1 and large superficial hematoma in 1 patient. Laparoscopic cholecystectomy is associated to a low morbidity and mortality and good postoperative outcome in transplant patients with uncomplicated cholecystitis.

Adolescence, the transition between childhood and adulthood, represents a time of rapid biological, neurocognitive, and psychosocial changes. These changes have important implications for the development and evolution of adolescent spirituality, particularly for adolescents with chronic or life-limiting illnesses. To contribute positively to adolescent spiritual formation, palliative care teams benefit from understanding the normative changes expected to occur during adolescence. This paper provides a narrative review of adolescent spirituality while recognizing the role of religious, familial, and cultural influences on spiritual development during the teenage years. By giving explicit attention to the contextual norms surrounding adolescence and still recognizing each adolescent-aged patient as unique, palliative care teams can help adolescents transition toward meaningful and sustainable spiritual growth. This paper reviews the clinical and research implications relevant to integrating adolescent spiritual health as part of comprehensive palliative care.
Full Text Available Prosthesis-patient mismatch (PPM is present when the effective orifice area of the inserted prosthetic valve is too small in relation to body size. Its main hemodynamic consequence is to generate higher than expected gradients through normally functioning prosthetic valves. The purpose of this review is to present an update on the present state of knowledge with regards to diagnosis, prognosis and prevention of PPM. PPM is a frequent occurrence (20%–70% of aortic valve replacements that has been shown to be associated with worse hemodynamics, less regression of left ventricular hypertrophy, more cardiac events, and lower survival. Moreover, as opposed to most other risk factors, PPM can largely be prevented by using a prospective strategy at the time of operation.

To determine the patient compliance in completing electronically administered patient-reported outcome (PRO) scores following shoulder arthroscopy, and to determine if dedicated research assistants improve patient compliance. Patients undergoing arthroscopic shoulder surgery from January 1, 2014, to December 31, 2014, were prospectively enrolled into an electronic data collection system with retrospective review of compliance data. A total of 143 patients were included in this study; 406 patients were excluded (for any or all of the following reasons, such as incomplete follow-up, inaccessibility to the order sets, and inability to complete the order sets). All patients were assigned an order set of PROs through an electronic reporting system, with order sets to be completed prior to surgery, as well as 6 and 12 months postoperatively. Compliance rates of form completion were documented. Patients who underwent arthroscopic anterior and/or posterior stabilization were excluded. The average age of the patients was 53.1 years, ranging from 20 to 83. Compliance of form completion was highest preoperatively (76%), and then dropped subsequently at 6 months postoperatively (57%) and 12 months postoperatively (45%). Use of research assistants improved compliance by approximately 20% at each time point. No differences were found according to patient gender and age group. Of those completing forms, a majority completed forms at home or elsewhere prior to returning to the office for the clinic visit. Electronic administration of PRO may decrease the amount of time required in the office setting for PRO completion by patients. This may be mutually beneficial to providers and patients. It is unclear if an electronic system improves patient compliance in voluntary completion PRO. Compliance rates at final follow-up remain a concern if data are to be used for establishing quality or outcome metrics. Level IV, case series. Copyright © 2017 Arthroscopy Association of North
Patients as Experts: Determining Benefit by Using Assessments of Ability (ICIDH)When health economy and quality mangement are dealing with the cost-benefit relationship, to this day description, calculation, and assessment of the benefit are missing to a great extent. Deliberations in terms of cause and effect do not go beyond the model of pathogenesis (etiology - pathology - manifestation) and descriptions on the organ level (ICD). Only the international classification of impairments, disabilities, and handicaps (ICIDH) as a separate estimation of the resulting manifestations of illness on the levels of organ, individual, and society is capable to elucidate this benefit. It is the patient who is the expert to decide what he needs, what he wants, and what he can do, thus, evaluating on an individual level his loss of capability. The ICIDH is regarded as the key for the management of chronic diseases. The characteristics of being chronically ill require the integration of salutogenesis and the consideration of the hierarchy of needs. The specially developed MARA model serves as pragmatic basis for the description of the benefits of carried out and omitted interventions as changes of abilities by using the MARA curve (mean age-related ability) as ethical guideline. In quality circles the MARA model, which is based on ICIDH, hierarchy of needs and salutogenesis, can offer apatient-oriented basis of discussion for benefit assessments, and, in a pragmatical way, it can facilitate the introduction of evidence-based medicine. By the change of view from the organ level with multifactorial aspects to the individual level, in which the abilities can be understood as a monofactor, a high consensus potential between several participants of discussion in health service is possible.

Full Text Available Introduction: Surgery for bladder exstrophy has been evolving over the last four to five decades. Because survival has become almost universal, the focus has changed in the exstrophy-epispadias complex to improving quality of life. The most prevalent problem in the long-term function of exstrophy patients is the sexual activity of the adolescent and adult males. The penis in exstrophy patients appears short because of marked congenital deficiency of anterior corporal tissue. Many patients approach for genital reconstruction to improve cosmesis as well as to correct chordee. We report our series of male patients seeking genital reconstruction following exstrophy repair in the past. Materials and Methods: Fourteen adolescent/adult male patients attended urology services during the period January 2000-December 2009 seeking genital reconstruction following exstrophy repair in the past. Results: Three patients underwent epispadias repair, four patients had chordee correction with cosmetic excision of skin tags and seven patients underwent chordee correction with penile lengthening. All patients reported satisfaction in the answered questionnaire. Patients undergoing penile lengthening by partial corporal dissection achieved a mean increase in length of 1.614 ± 0.279 cm dorsally and 1.543 ± 0.230 cm ventrally. The satisfactory rate assessed by the Short Form-36 (SF-36 showed that irrespective of the different genital reconstructive procedures done, the patients were satisfied with cosmetic and functional outcome. Conclusions: Surgical procedures have transformed the management in these patients with bladder exstrophy. Bladders can be safely placed within the pelvis, with most patients achieving urinary continence and cosmetically acceptable external genitalia. Genital reconstruction in the form of correction of chordee, excision of ugly skin tags and lengthening of penis can be performed to give the patients a satisfactory cosmetic and functional

Background: As a result of increased interest and public demand, providing patients with adequate information about radiooncology has become more and more difficult for the doctor. Insufficient patient information can not only cause anxiety for the patient, but can also lead to legal action against the physician. In order to gain a deeper insight into our clinical practice of providing patient information, we developed a special questionnaire. We describe our first experiences in using this questionnaire at our institute. Patients and methods: We examine the amount of information and level of satisfaction, as well as the agreement of assessment between patient and physician after the provision of standard patient information before and at the end of radiotherapy. 51 consecutive patients were interviewed with a newly designed questionnaire. The first questioning with 13 items was carried out before radiotherapy and the second with ten items was done at the end of treatment. Sum scores for information and satisfaction were defined and agreement was measured by the weighted κ coefficient. Results: Global level of information and satisfaction was good, and a significant increase in information level and a significant decline in satisfaction were seen between questionnaire 1 and 2. Agreement between patient and physician was fair, for example intent of treatment resulted in a κ coefficient of 0.34, and poor for the doctor's role with a κ coefficient of -0.002. Only 52% of the patients who received palliative radiotherapy rated correctly the non-curative intent of treatment, whereas 86% of the patients who received curative radiotherapy made a correct statement. Before radiotherapy, emotional state was often both negatively and positively assessed by the patients. Conclusion: Our short questionnaire is simple and easy to understand. It provides insights into patient information with respect to assessment of the information, satisfaction level, and agreement between

Recently, the patient's role in preventing adverse events has been emphasized. Patients who are more knowledgeable about safety issues are more likely to engage in safety initiatives. Therefore, nurses need to develop techniques and tools that increase patients' knowledge in preventing adverse events. For this reason, an educational smartphone application for patient safety called "Safe Patients" was developed through an iterative process involving a literature review, expert consultations, and pilot testing of the application. To determine the effect of "Safe Patients," it was implemented for patients in surgical units in a tertiary hospital in South Korea. The change in patients' knowledge about patient safety was measured using seven true/false questions developed in this study. A one-group pretest and posttest design was used, and a total of 123 of 190 possible participants were tested. The percentage of correct answers significantly increased from 64.5% to 75.8% (P effectively improve patients' knowledge of safety issues. This will ultimately empower patients to engage in safe practices and prevent adverse events related to surgery.

Electroconvulsive therapy (ECT) is a potent and successful method for the treatment of severe psychiatric disorders. Severe depressive and psychotic disorders may lead to legal incapacity and inability to consent. In Germany, administration of ECT against the patient's will is feasible under certain constellations and is regulated under the terms of the guardianship law. This article outlines the prevalence, effectiveness and tolerability of ECT when applied in nonconsenting patients. Case report and literature review. The literature on ECT as a treatment in nonconsenting patients is relatively sparse. In 2008 the prevalence in Germany was less than 0.5 % of all patients receiving ECT. Case reports and case series suggest a good and equal level of effectiveness when compared to consenting patients. In the course of treatment the majority of patients consented to receive further ECT and retrospectively judged ECT as helpful. The use of ECT is a highly effective treatment in severe psychiatric disorders even when administered as treatment in nonconsenting patients. It can be lifesaving and lead to a rapid improvement of symptoms and relief from severe suffering also from the patients' perspective. Thus, it seems unethical not to consider ECT as a treatment against the nonautonomous will of legally incompetent patients in individual cases. Nevertheless, physicians should always seek to obtain the patients' consent as soon as possible for both legal and ethical reasons.
Full Text Available Given the importance of patient's rights in healthcare, special attention has been given to the concept of patient's rights by the Ministry of Health and Medical Education in Iran. Iranian patient's rights charter has been compiled with a novel and comprehensive approach. This charter aims to elucidate rights of recipients of health services as well as observing ethical standards in medicine. This paper presents the Iranian patient's rights charter. Based on a study done from 2007 to 2009, the charter has been finalized through an extensive consultation involving all stakeholders, patients, physicians, nurses, lawyers, patient associations and health policy makers. The developed charter was adopted by the Ministry of Health in December 2009. Iranian patient's rights charter has been formulated in the framework of 5 chapters and 37 articles including vision and an explanatory note. The five chapters concern right to receiving appropriate services, right to access desired and enough information, right to choose and decide freely about receiving healthcare, right to privacy and confidentiality, and finally right to access an efficient system of dealing with complaints which have been explained in 14, 9, 7, 4 and 3 articles, respectively. The paper concludes that, adopting the patient's rights charter is a valuable measure to meet patient's rights; however, a serious challenge is how to implement and acculturate observing patient's rights in practice in our healthcare system in Iran.
Healthcare industry continues to evolve under conditions of intense competition in approaching health prevention, protection, and promotion. Therefore, healthcare providers are challenged to always ensure better patient experience, winning patients' satisfaction, and loyalty and remain competitive on today's healthcare market. Healthcare markets bring together professionals and their patients into real collaborative relationships, which empower patients to contribute to the healthcare improvement. Within this competitive landscape, which is also characterized by digital health tools boosting patients' awareness and controlling their own health, medical providers need to be perceived as skilled and trustworthy in relying on patients' needs, expectations, and sacrifices are required in order to obtain the promised benefits. Moreover, while constantly providing a holistic assessment of the healthcare services' and experience attributes, acting on feedback and reaching healthcare service excellence, providing a better understanding of all the touch points with their patients and improving the quality and consistency of all these touch points, all these are achieved by employees, who are truly connected to the healthcare business. Today, patients are systematically becoming aware of the diversity of their choices, being increasingly involved in making better healthcare choices, and, so, more and more innovative products are introduced, targeting new patient segments. Findings from the last three years have shown that patients may achieve better outcomes due to the stakeholders' commitment to innovation within the context of the big-data revolution, by building new values.

The patient-centered medical home is an innovative approach to improve health care outcomes. To address the unique needs of patients with intellectual and developmental disabilities (IDDs), a large health care provider reevaluated the National Committee for Quality Assurance's 6 medical home standards: (a) enhance access and continuity, (b) identify and manage patient populations, (c) plan and manage care, (d) provide self-care and community support, (e) track and coordinate care, and (f) measure and improve performance. This article describes issues to consider when serving patients with IDDs.

Transfusions are common in hospitalized patients but carry significant risk, with associated morbidity and mortality that increases with each unit of blood received. Clinical trials consistently support a conservative over a liberal approach to transfusion. Yet there remains wide variation in practice, and more than half of red cell transfusions may be inappropriate. Adopting a more comprehensive approach to the bleeding, coagulopathic, or anemic patient has the potential to improve patient care. We present a patient-centered blood management (PBM) paradigm. The 4 guiding principles of effective PBM that we present include anemia management, coagulation optimization, blood conservation, and patient-centered decision making. PBM has the potential to decrease transfusion rates, decrease practice variation, and improve patient outcomes. PBM's value proposition is highly aligned with that of hospital medicine. Hospitalists' dual role as front-line care providers and quality improvement leaders make them the ideal candidates to develop, implement, and practice PBM. © 2013 Society of Hospital Medicine.

Communication among physicians, staff, and patients is a critical element in patient safety. Effective communication skills can be taught and improved through training and awareness. The practice of family medicine allows for long-term relationships with patients, which affords opportunities for ongoing, high-quality communication. There are many barriers to effective communication, including patient factors, clinician factors, and system factors, but tools and strategies exist to address these barriers, improve communication, and engage patients in their care. Use of universal precautions for health literacy, appropriate medical interpreters, and shared decision-making are evidence-based tools that improve communication and increase patient safety.

INTRODUCTION: Lung cancer remains a leading cause of cancer-related death. The incidence increases with age and the occurrence in young patients is relatively low. The clinicopathological features of lung cancer in younger patients have not been fully explored previously. METHODS: To assess the age...... differences in the clinical characteristics of lung cancer, we conducted a retrospective analysis comparing young patients ≤ 65 years of age with an elderly group > 65 years of age. Among 1,232 patients evaluated due to suspicion of lung cancer in our fast-track setting from January-December 2013, 312 newly...... diagnosed lung cancer patients were included. RESULTS: Patients ≤ 65 years had a significantly higher representation of females (p = 0.0021), more frequent familial cancer aggregation (p = 0.028) and a lower incidence of squamous cell carcinoma (p = 0.0133). When excluding pure carcinoid tumours...

Patients admitted to the ICU after severe trauma require frequent procedures in the operating room, particularly in cases where a damage control strategy is used. The ventilatory management of these patients in the operating room can be particularly challenging. These patients often have severely impaired respiratory mechanics because of acute lung injury and abdominal compartment syndrome. Consequently, the pressure and flow generation capabilities of standard anesthesia ventilators may be inadequate to support ventilation and gas exchange. This article presents the problems that may be encountered in patients who have severe abdominal and lung injuries, and the current management concepts used in caring for these patients in the critical care setting, to provide guidelines for the anesthetist faced with these patients in the operating room.

This study comprises 81 thyrotoxic patients with onset after the age of 60. In elderly persons, toxic multinodular goiter is the most common cause (68%) of hyperthyroidism, followed by solitary thyroid nodules (16%) and Graves' disease (16%). Cardiovascular disorders (cardiac failure, arrythmias etc.) constitute the first and often the only symptom in 62% of the cases. The other forms of appearance are both various and deceptive: depression, slight fever, asthenia or nausea. Separate analysis of the three forms of hyperthyroidism did not reveal clinical, biological or therapeutic differences between them, except an inferior rate of captation for the toxic nodules. Isolated measurement of T3 or T4 is often insufficient to confirm the diagnosis because either of these hormones may appear at a normal rate. In three cases only the free thyroxin index was pathological on first determination. The authors have established that the autonomous nodules are larger and more active after, rather than before, 60 years of age, and have attempted to define their morphological identity. The results of the treatment are analyzed and preference is expressed for radioactive iodine in every form of hyperthyroidism.

Due to the large surface area, heat, high humidity and high oxygen supply in the lung makes an ideal environment for the propagation of germs. The purpose of the immune system is to establish and maintain the balance between saprophytes and immune defense so as to depress and ultimately kill germs as they infiltrate the body. This usually is achieved by the use of a highly complex immune system. It is a perfect combination of non-specific, cellular and humoral immune mechanisms with very specific immune cells and antibodies, which are specialized on particular pathogens. The specific defenses potentiate the effect of the nonspecific defense in a large extent so as to prevent re-infection and ultimately eliminate recognized pathogens. The causes of immune deficiency can be related to either the cellular or humoral level and affect both the specific and nonspecific defenses. There is a different excitation spectrum depending on the type of immune deficiency. Immune deficiency can prevalently cause complications in the course of infections, decelerate the healing and allow the occurrence of rare pathogens. In particular, the radiological characteristics of typical and atypical pneumonia in immunocompromised patients will be discussed. Particular emphasis is placed on the appearance of bacterial infections, mycobacterioses, PCP, CMV, and laid fungual pneumonia. Even it is not possible to identify certain pathogens radiologically, it is often possible to narrow the spectrum of germs causing pulmonary infections significantly by comparing with other pulmonary complications such as lymphoma or kaposisarcomas.

The traditional approach to patient safety in health care has ranged from reticence to outward denial of serious flaws. This undermines the otherwise remarkable advances in technology and information that have characterized the specialty of medical practice. In addition, lessons learned in industries outside health care, such as in aviation, provide opportunities for improvements that successfully reduce mishaps and errors while maintaining a standard of excellence. This is precisely the call in medicine prompted by the 1999 Institute of Medicine report ''To Err Is Human: Building a Safer Health System.'' However, to effect these changes, key components of a successful safety system must include: (1) communication, (2) a shift from a posture of reliance on human infallibility (hence ''shame and blame'') to checklists that recognize the contribution of the system and account for human limitations, and (3) a cultivation of non-punitive open and/or de-identified/anonymous reporting of safety concerns, including close calls, in addition to adverse events.

A physician who communicates in a patient-centered way is a physician who adapts his or her communication style to what each patient needs. In order to do so, the physician has to (1) accurately assess each patient's states and traits (interpersonal accuracy) and (2) possess a behavioral repertoire to choose from in order to actually adapt his or her behavior to different patients (behavioral adaptability). Physician behavioral adaptability describes the change in verbal or nonverbal behavior a physician shows when interacting with patients who have different preferences in terms of how the physician should interact with them. We hypothesized that physician behavioral adaptability to their patients' preferences would lead to better patient outcomes and that physician interpersonal accuracy was positively related to behavioral adaptability. To test these hypotheses, we recruited 61 physicians who completed an interpersonal accuracy test before being videotaped during four consultations with different patients. The 244 participating patients indicated their preferences for their physician's interaction style prior to the consultation and filled in a consultation outcomes questionnaire directly after the consultation. We coded the physician's verbal and nonverbal behavior for each of the consultations and compared it to the patients' preferences to obtain a measure of physician behavioral adaptability. Results partially confirmed our hypotheses in that female physicians who adapted their nonverbal (but not their verbal) behavior had patients who reported more positive consultation outcomes. Moreover, the more female physicians were accurate interpersonally, the more they showed verbal and nonverbal behavioral adaptability. For male physicians, more interpersonal accuracy was linked to less nonverbal adaptability.

The identification of patient plays a key role in the quality and safety of radiotherapy. It does impact on all professional staff and on patients. After the regulatory authority approval (Cnil), a pilot study has been performed on 1901 patients. Acceptance has been very high (> 93%) with a low risk of mis-identification (< 0.1%). The next step will be to implement and test a bimodal system in order to improve registration capacity and sensitivity. (authors)

Parenteral nutrition became a routine therapeutic option in malnourished patients, if conventional nutritional enteral support is not effective. Cachexia and malnutrition prolong the wound healing, contribute to immunosuppression, increase morbidity and the cost of treatment. Using of a malnutrition protocol as a screening tool is necessary to sort out malnourished patients. Parenteral nutrition is therefore an important part of the multimodal therapy and from the medical and the ethical point of view is a great mistake not to feed a patient. (author)

Full Text Available With the increased number of geriatric population, it is predicted that the need for dental treatment also increases. The needs for esthetic factors and function of geriatric patient are maybe similar to young patient. The number of geriatric patients who refuse dental extraction is increasing if there are still other alternative. They can be more convinced when the clinician said that the dental disease experienced is a focal infection so that the loss of the tooth can be accepted as the best option. But if it is possible, they will prefer endodontic treatment, because they want to keep their teeth according to the treatment plan or based on patient's request, as a less traumatic alternative compared to extraction.Endodontic treatment consideration for geriatric patient is quite similar to younger patients. The technique is also the same, although the problem may be bigger. The problem or obstacle that may arise in endodontic treatment for geriatric patient relates to the visit duration, problems during x-ray, problems in defining root canal location, vertical root fracture, and in some cases, decreased pulp tissue recovery ability. Due to the fact that the challenge is quite big, the success of endodontic treatment in geriatric patients needs to be considered. This paper will explain the endodontic treatment prognosis for geriatric patients.

Background Amid a national nurse shortage, there is growing concern that high levels of nurse burnout could adversely affect patient outcomes. Objectives This study examines the effect of the nurse work environment on nurse burnout, and the effects of the nurse work environment and nurse burnout on patients' satisfaction with their nursing care. Research Design/Subjects We conducted cross-sectional surveys of nurses (N = 820) and patients (N = 621) from 40 units in 20 urban hospitals across the United States. Measures Nurse surveys included measures of nurses' practice environments derived from the revised Nursing Work Index (NWI-R) and nurse outcomes measured by the Maslach Burnout Inventory (MBI) and intentions to leave. Patients were interviewed about their satisfaction with nursing care using the La Monica-Oberst Patient Satisfaction Scale (LOPSS). Results Patients cared for on units that nurses characterized as having adequate staff, good administrative support for nursing care, and good relations between doctors and nurses were more than twice likely as other patients to report high satisfaction with their care, and their nurses reported significantly lower burnout. The overall level of nurse burnout on hospital units also affected patient satisfaction. Conclusions Improvements in nurses' work environments in hospitals have the potential to simultaneously reduce nurses' high levels of job burnout and risk of turnover and increase patients' satisfaction with their care.

Though the mandibular swing, as an approach to certain upper aerodigestive tract malignancies, has been gaining popularity in recent years, there has been little reported as to the feasibility of this procedure in subjects who have received radical preoperative radiotherapy. We have recently reported the results of 23 such patients, and we now present an update. The results presented are of a retrospective analysis of 44 patients, 50% of whom received radical preoperative radiotherapy to fields including the osteotomy site. As in the previous study, there were no statistically significant differences between the complication rates in the irradiated and nonirradiated patient populations. All the patients were orally rehabilitated
Full Text Available Abstract Background Patients have the potential to provide a rich source of information on both organisational aspects of safety and patient safety incidents. This project aims to develop two patient safety interventions to promote organisational learning about safety - a patient measure of organisational safety (PMOS, and a patient incident reporting tool (PIRT - to help the NHS prevent patient safety incidents by learning more about when and why they occur. Methods To develop the PMOS 1 literature will be reviewed to identify similar measures and key contributory factors to error; 2 four patient focus groups will ascertain practicality and feasibility; 3 25 patient interviews will elicit approximately 60 items across 10 domains; 4 10 patient and clinician interviews will test acceptability and understanding. Qualitative data will be analysed using thematic content analysis. To develop the PIRT 1 individual and then combined patient and clinician focus groups will provide guidance for the development of three potential reporting tools; 2 nine wards across three hospital directorates will pilot each of the tools for three months. The best performing tool will be identified from the frequency, volume and quality of reports. The validity of both measures will be tested. 300 patients will be asked to complete the PMOS and PIRT during their stay in hospital. A sub-sample (N = 50 will complete the PMOS again one week later. Health professionals in participating wards will also be asked to complete the AHRQ safety culture questionnaire. Case notes for all patients will be reviewed. The psychometric properties of the PMOS will be assessed and a final valid and reliable version developed. Concurrent validity for the PIRT will be assessed by comparing reported incidents with those identified from case note review and the existing staff reporting scheme. In a subsequent study these tools will be used to provide information to wards/units about their

A review of the following points was performed: Factors favouring the development and presence of malnutrition among hospitalized patients. Useful parameters in nutritional evaluation. Types of malnutrition. The Chang nutritional evaluation protocol is used in our Hospital, which is simple, inexpensive, reliable, specific and easily reproduced. This is based on five variables (three anthropometric and two biochemical), randomized and based on reference tables and values. A study was made on data corresponding to 70 patients, in whom a prevalence of malnutrition was observed in critical patients. The patients were classified based on three different definitive possibilities (Marasmo, Kwashiorkor and combined), and three grades of malnutrition (slight, moderate and severe).

Full Text Available Although there are very few published studies on adherence to treatment regimens in chronic obstructive pulmonary disease (COPD, the evidence that exists suggests that, as with asthma therapy, adherence is poor. Patient beliefs about COPD, as well as their motivation and expectations about the likelihood of success of medical interventions, can influence adherence rates. Other critical factors include the patient's understanding of their illness and therapy, and the complexity of the prescribed treatment regimen. Incorrect inhaler technique is also a common failing. When prescribing in primary or specialist care, healthcare professionals should address adherence as a vital part of the patient consultation. Improved patient education may also increase adherence rates.

Spinal cord injuries are one of the traumatic injuries which produce the greatest number of patients who are bedridden or incapacitated. Physical effects acquire such importance that one can not forget to attend to aspects as basic as hygiene, correct posture during their bedridden stay or the daily task to transfer patients to the various support elements they need to utilize. Nursing care for patients suffering spinal cord injuries comprise the fundamental axis on which a correct recuperation rotates. At the same time, proper treatment care will lead to a future improvement in a patient's quality of life.

Objectives: To stratify patients into various stages, calculate average patient delay and study various causes of delay to presentation. Methodology: This was a one year hospital based cross sectional study at Khyber Teaching Hospital, using non probability consecutive sampling. A simplified staging was used for this study; Early (Stage I), Intermediate (Stage II, III), and Late (Stage IV). A patient was labelled delay when >3 months had elapsed between first symptom perception and first doctor consultation. Results: 80 patients were included with age 21-80 years (mean 45.28+-13.15). 80% of the patients were married, 76.3% (n=61/80) were poor with annual income of <500 US $, 85% of patients were illiterate. The participants from Rural and Urban areas were similar (37 % vs 31%); 15% were from Afghanistan. 80% patients presented with a delay of >3 months. Most common cause of delay was false symptom interpretation in 25.3% (n=17) patients. Conclusion: Late clinical presentation is because of lack of health education, unawareness, misconceptions about treatment and strong belief in traditional medicine resulting in advanced disease. This is worsened by poverty and unavailability of health care services especially in rural areas. (author)
Full Text Available Background: Inadequate health literacy in adults is a nationwide issue that is associated with worse health outcomes. There is a paucity of literacy regarding rates of inadequate health literacy in psychiatric populations. Objective: The aim of the study was to identify an existing tool that would easily identify patients who had inadequate health literacy, so that a targeted intervention could be performed. Secondarily we attempted to compare rates of inadequate health literacy with providers’ perception of patients’ health literacy. Methods: We assessed health literacy in a psychiatric population by administering the Brief Health Literacy Survey (BHLS. Additionally, all psychiatry residents, psychiatrists, nurse practitioners, pharmacists, and social workers were surveyed to assess their perception of patient health literacy. Differences between patient health literacy and provider expectations of patient health literacy were compared. Results: Inadequate health literacy was identified in 31 out of 61 patients (50.8% using 2 questions from the BHLS. Only 9 (29% of patients who were identified as having inadequate health literacy were identified by both BHLS questions. In contrast, almost 100% of providers identified their patients, in general, as having inadequate health literacy. Conclusions: These results identify a higher rate of health literacy in a psychiatric inpatient population than in the general population. However, providers at this institution likely over-identify health literacy. This highlights the need for a health literacy tool that can easily target patients with inadequate health literacy for an intervention.

Terms such as 'cultural competence' and 'transcultural nursing' have comfortably taken their place in the lexicon of health care. Their high profile is a reflection of the diversity of western societies and health care's commitment to provide care that is responsive to the values and beliefs of all who require treatment. However, the relationship between cultural competence and familiar ethical concepts such as patient autonomy has been an uneasy one. This article explores the moral foundations of cultural competence, ultimately locating them in patient autonomy and patient good. The discussion of patient good raises questions about the moral relevance of a value's rootedness in a particular culture. I argue that the moral justification for honoring cultural values has more to do with the fact that patients are strongly committed to them than it does with their cultural rootedness. Finally, I suggest an organizational approach to cultural competence that emphasizes overall organizational preparedness.

Patient-controlled analgesia (PCA) is a relatively new technique in which patients are able to self-administer small doses of opioid analgesics when needed. Many different devices are available for opioid infusion, including a syringe pump, disposable plastic cylinder, and battery-operated computer-driven pump. These devices allow patients to choose an intermittent (demand) bolus, continuous infusion, or both modes of administration. Parameters, such as route, drug concentration dose, frequency, and maximum daily or hourly dose, are programmed by the physician. The patient decides whether or not to take a dose. Devices can be used to deliver the drug into a running intravenous infusion, the epidural space, or subcutaneously. Controlled trials indicate that PCA is probably superior to regular opioid administration in postoperative pain. Reported advantages include greater patient satisfaction, decreased sedation and anxiety, and reduced nursing time and hospitalization. Preliminary experience suggests that PCA is also useful and safe for cancer pain, but further research is greatly needed.

This article describes the factors that motivated the nursing staff of the cardiac surgery unit at the Royal Victoria Hospital in Montreal, to revise their preoperative teaching program. The motivating factors described are the length of the preoperative waiting period; the level of preoperative anxiety; the decreased length of hospital stay; the dissatisfaction of the nursing staff with current patient teaching practices; and the lack of available resources. The reorganization of the teaching program was based upon the previously described factors combined with a review of the literature that demonstrated the impact of preoperative anxiety, emotional support and psycho-educational interventions upon the client's recovery. The goals of the new teaching program are to provide the client and the family with cognitive and sensory information about the client's impending hospitalization, chronic illness and necessary lifestyle modifications. The program consists of a system of telephone calls during the preoperative waiting period; a videotape viewing; a tour of the cardiac surgery unit; informal discussion groups; and the availability of nursing consultation to decrease preoperative anxiety. The end result of these interventions is more time for client support and integration of necessary information by the client and family. This kind of program has the potential to provide satisfaction at many levels by identifying client's at risk; increasing client knowledge; increasing support; decreasing anxiety during the preoperative waiting period; and decreasing the length of hospital stay. The nursing staff gained a heightened sense of accomplishment because the program was developed according to the nursing department's philosophy, which includes primary nursing.(ABSTRACT TRUNCATED AT 250 WORDS)
Autonomy and consent have been central values in Western moral and political thought for centuries. One way of understanding the bioethical models that started to develop, especially in the 1970s, is that they were about the fusion of a long-standing professional ethics with the core values underpinning modern political institutions. That there was a need for this kind of fusion is difficult to dispute, especially since the provision of health care has in most developed countries become an ever more important concern of our political institutions, with governments playing a significant role in regulating and facilitating the provision of health care and in many countries even largely organizing it. There is, nevertheless, still room for dispute about how best to achieve this fusion and how to best think about autonomy and consent in a biomedical context. The simplest model we can have is probably about how being a person is largely about having the capacity of autonomous choice and that the main mode through which we exercise autonomy is by providing informed consent. Yet, liberal democracy's core idea that human beings have a high and equal value is also found in other accounts of the person. The human-rights framework provides an alternative model for thinking about personhood and about patient care. The human-rights approach is grounded, not in an account of autonomy (although it has something to say about autonomy), but in an account of the moral and political personhood that people possess merely by being human beings. In this approach, values like dignity and integrity, both highly relevant in a bioethical context, are identified as distinct values rather than being derived from and therefore reduced to respect for autonomous choice. The human-rights approach can supplement the problematic notion of autonomy that has been central to bioethics by placing this notion in a broader, strongly pluralistic framework. © 2017 The Hastings Center.

Patient satisfaction with emergency care is associated with timeliness of care, empathy, technical competence, and information delivery. Previous studies have demonstrated inconsistent findings regarding the association between pain management and patient satisfaction. This study was undertaken to determine the association between pain management and patient satisfaction among Emergency Department (ED) patients presenting with acute painful conditions. In this survey study, a standardized interview was conducted at the Emergency Department at the University of Toledo Medical Center in May-July 2011. Participants were asked to answer 18 questions pertaining to patient satisfaction. Additional data collected included demographic information, pain scores, and clinical management. Among 328 eligible participants, 289 (88%) participated. The mean triage pain score on the verbal numeric rating scale was 8.2 and the mean discharge score was 6.0. The majority of patients (52%) experienced a reduction in pain of 2 or more points. Participants received one pain medication dose (44%), two medication doses (14%), three medication doses (5%), or four medication doses (2%). Reduction in pain scores of 2 or more points was associated with a higher number of medications administered. Reduction in pain scores was associated with higher satisfaction as scored on questions of patient perceptions of adequate assessment and response to pain, and treatment of pain. There was a significant association between patient satisfaction and a reduction in pain of 2 or more points and number of medications administered. Effective pain management is associated with improved patient satisfaction among ED patients with painful conditions. Copyright © 2014 Elsevier Inc. All rights reserved.

There is a very high prevalence of Erectile Dysfunction (ED) in dialysis patients. There is no as such available data on ED and factors affecting it in our patients. Analytical, cross-sectional, hospital based study conducted from January to March 2008, Haemodialysis unit of Shalimar and Mayo Hospital, Lahore. All male patients of end stage renal disease (ESRD) on maintenance haemodialysis therapy, whose spouses are alive and able to perform intercourse, were included in the study. Patient with cognitive and communication deficits were excluded from study. International index of erectile function-5 (IIEF-5), adopted in Urdu was used for the determination of prevalence of erectile function. Categorization of erectile dysfunction was done as mild, moderate and severe. Demographic data were collected and certain laboratory parameters (haemoglobin, haematocrit, urea, HBsAg and Anti HCV) were sent. Total numbers of patient were fifty. Major cause of ESRD was diabetes mellitus 28 (56%). Most of the patients 33 (66%) have passed 10th grade or they were under 10th grade. Prevalence of ED was 86% with mean IIEF-5 score of 10.36+-7.13. Majority of patients 33 (64.7%) were suffering from severe degree of ED. Factors responsible for ED are diabetes mellitus, age more than 50 year, high pre dialysis urea and Anti HCV positive patients. In this study, smoking, duration of dialysis and monthly spending is not related with ED. Majority of the patients suffering from ESRD, on maintenance haemodialysis are having ED. None of the patients suffering from ED were taking any treatment for it. Haemodialysis does not improve sexual dysfunction. Major factors responsible for ED are diabetes mellitus, age more than 50 years, high pre dialysis urea and Anti HCV positive patients. (author)

To analyze the hospital outcomes of patients, with chronic renal insufficiency in the hemodialysis, submitted to OPCAB. Fifty-one patients with chronic renal insufficiency were submitted to OPCAB. Hemodialysis was performed on the day before and the day after the operation. Myocardial revascularization was performed using LIMA's suture and suction stabilization. Fifty-one patients, with an average of 61.28+/-11.09 years, were analyzed. Thirty patients (58.8%) were female. The predominant functional class was IV in 21 (41.1%) of the patients. The left ventricle ejection fraction was dire in 21 (41.1%) patients. The mean EUROSCORE of this series was 7.65+/-3.83 and the mean number of distal anastomosis was 3.1+/-0.78 per patient. The average time of mechanical ventilation was 3.78+/-4.35 hours and the mean ICU stay was 41.9+/-13.8 hours, while the average hospitalization was 6.5+/-1.31 days. In respect to complications, nine (17.6%) of the patients developed atrial fibrilation, and one (1.9%) patient presented with a case of ischemic stroke but had a good recovery during hospitalization. There were no deaths in this series. Chronic renal patients submitted to hemodialysis were always a high risk population for myocardial revascularization. In this series, the absence of extracorporeal circulation appeared to be safe and efficient in this special subgroup of patients. The operations were performed with low indices of complications, absence of deaths and relatively low stays in the ICU and in hospital.

Patient safety is considered to be crucial to healthcare quality and is one of the major parameters monitored by all healthcare organizations around the world. Nurses play a vital role in maintaining and promoting patient safety due to the nature of their work. The purpose of this study was to investigate nurses' perceptions about patient safety culture and to identify the factors that need to be emphasized in order to develop and maintain the culture of safety among nurses in Oman. A descriptive and cross-sectional design was used. Patient safety culture was assessed by using the Hospital Survey on Patient Safety Culture among 414 registered nurses working in four major governmental hospitals in Oman. Descriptive statistics and general linear regression were employed to assess the association between patient safety culture and demographic variables. Nurses who perceived more supervisor or manager expectations, feedback and communications about errors, teamwork across hospital units, and hospital handoffs and transitions had more overall perception of patient safety. Nurses who perceived more teamwork within units and more feedback and communications about errors had more frequency of events reported. Furthermore, nurses who had more years of experience and were working in teaching hospitals had more perception of patient safety culture. Learning and continuous improvement, hospital management support, supervisor/manager expectations, feedback and communications about error, teamwork, hospital handoffs and transitions were found to be major patient safety culture predictors. Investing in practices and systems that focus on improving these aspects is likely to enhance the culture of patient safety in Omani hospitals and others like them. Strategies to nurture patient safety culture in Omani hospitals should focus upon building leadership capacity that support open communication, blame free, team work and continuous organizational learning. © 2014 International

The aim of this study was to objectively assess the patients' acceptance for awake craniotomy in a group of neurosurgical patients, who underwent this procedure for removal of lesions in or close to eloquent brain areas. Patients acceptance for awake craniotomy under local anesthesia and conscious sedation was assessed by a formal questionnaire (PPP33), initially developed for general surgery patients. The results are compared to a group of patients who had brain surgery under general anesthesia and to previously published data. The awake craniotomy (AC) group consisted of 37 male and 9 female patients (48 craniotomies) with age ranging from 18 to 71 years. The general anesthesia (GA) group consisted of 26 male and 15 female patients (43 craniotomies) with age ranging from 26 to 83 years. All patients in the study were included in the questionnaire analysis. In comparison to GA the overall PPP33 score for AC was higher (p=0.07), suggesting better overall acceptance for AC. The subscale scores for AC were also significantly better compared to GA for the two subscales "postoperative pain" (p=0.02) and "physical disorders" (p=0.01) and equal for the other 6 subscales. The results of the overall mean score and the scores for the subscales of the PPP33 questionnaire verify good patients' acceptance for AC. Previous studies have shown good patients' acceptance for awake craniotomy, but only a few times using formal approaches. By utilizing a formal questionnaire we could verify good patient acceptance for awake craniotomy for the treatment of brain tumors in or close to eloquent areas. This is a novel approach that substantiates previously published experiences. Copyright © 2011 Elsevier B.V. All rights reserved.

Given that a new wave of biosimilar insulins will likely enter the market in coming years, it is important to understand patient perspectives on these biosimilars. A survey (N = 3214) conducted by the market research company dQ&A, which maintains a 10 000-patient panel of people with type 1 or type 2 diabetes in roughly equal measure, investigated these perspectives. The survey asked whether patients would switch to a hypothetical less expensive biosimilar insulin that was approved by their provider. Approximately 66% of respondents reported that they would "definitely" or "likely" use a biosimilar insulin, while 17% reported that they were "unlikely" to use or would "definitely not use" such a product. Type 2 diabetes patients demonstrated slightly more willingness to use biosimilars than type 1 diabetes patients. Common patient concerns included whether biosimilars would be as effective as reference products (~650 respondents), whether side effect profiles would deviate from those of reference products (~220 respondents), and the design of the delivery device (~50 respondents). While cost savings associated with biosimilar insulins could increase patient uptake, especially among patients without health insurance (some recent estimates suggest that biosimilars will come at a substantial discount), patients may still need assurance that a cheaper price tag is not necessarily associated with substandard quality. Overall, the dQ&A survey indicates that the majority of patients are willing to consider biosimilar insulins, but manufacturers will need to work proactively to address and assuage patient concerns regarding efficacy, safety, drug administration, and other factors. © 2014 Diabetes Technology Society.

The objectives of patient selection and counseling are ultimately to enhance successful outcomes. However, the definition for success is often narrowly defined in published literature (ability to complete surgery, complications, satisfaction) and fails to account for patient desires and expectations, temporal changes, natural history of underlying diseases, or independent validation. Factors associated with satisfaction and dissatisfaction are often surgery-specific, although correlation with pre-operative expectations, revisions, and complications are common with most procedures. The process of appropriate patient selection is determined by the integration of patient and surgeon factors, including psychological capacity to handle unsatisfactory results, baseline expectations, complexity of case, and surgeon volume and experience. Using this model, a high-risk scenario includes one in which a low-volume surgeon performs a complex case in a patient with limited psychological capacity and high expectations. In contrast, a high-volume surgeon performing a routine case in a male with low expectations and abundant psychiatric reserve is more likely to achieve a successful outcome. To further help identify patients who are at high risk for dissatisfaction, a previously published mnemonic is recommended: CURSED Patient (compulsive/obsessive, unrealistic, revision, surgeon shopping, entitled, denial, and psychiatric). Appropriate patient counseling includes setting appropriate expectations, reviewing the potential and anticipated risks of surgery, post-operative instruction to limit complications, and long-term follow-up. As thorough counseling is often a time-consuming endeavor, busy practices may elect to utilize various resources including educational materials, advanced practice providers, or group visits, among others. The consequences for poor patient selection and counseling may range from poor surgical outcomes and patient dissatisfaction to lawsuits, loss of

Treatment of the hypothermic patient depends more on the clinical condition than on the core temperature. Unconscious patients need thorough investigation, and they can often be rewarmed with warm water in the pleural cavities. Cardiac arrest requires cardio pulmonary rescue until rewarming can b...

This article explores the role of psychodynamics as it applies to the understanding and treatment of medically ill patients in the consultation-liaison psychiatry setting. It provides historical background that spans the eras from Antiquity (Hippocrates and Galen) to nineteenth-century studies of hysteria (Charcot, Janet, and Freud) and into the twentieth century (Flanders Dunbar, Alexander, Engle, and the DSM). The article then discusses the effects of personality on medical illness, treatment, and patients' ability to cope by reviewing the works of Bibring, Kahana, and others. The important contribution of attachment theory is reviewed as it pertains the patient-physician relationship and the health behavior of physically ill patients. A discussion of conversion disorder is offered as an example of psychodynamics in action. This article highlights the important impact of countertransference, especially in terms of how it relates to patients who are extremely difficult and "hateful," and explores the dynamics surrounding the topic of physician-assisted suicide, as it pertains to the understanding of a patient's request to die. Some attention is also given to the challenges surrounding the unique experience of residents learning how to treat medically ill patients on the consultation-liaison service. Ultimately, this article concludes that the use and understanding of psychodynamics and psychodynamic theory allows consultation-liaison psychiatrists the opportunity to interpret the life narratives of medically ill patients in a meaningful way that contributes importantly to treatment.

Full Text Available Cancer is accompanied by important psychological distress experienced by both patient and family. From the moment of the diagnosis on, the patient has to develop a great number of mechanisms and tasks of adjustment to the illness and its circumstances. The high prevalence of anxiety and depressive disorders during the course of cancer increases in the end stage disea‐ se. Therefore, a global plan of intervention integrating somatic and psychological/ psychiatric care throughout all the phases of the illness is crucial in the treatment of these patients. Health professionals working on this field can also experience emotional reactions to their patients’ suffering. They should be aware of the emotional aspects involved and develop training to help them intervene adequately with the patient and the family. The articulation between oncologists, palliative care professionals, and mental health care teams can be of great help in providing good quality of care to cancer patients.
Full Text Available Pulmonary complications are a major cause of morbidity and mortality in neurosurgical patients. The common pulmonary complications in neurosurgical patients include pneumonia, postoperative atelectasis, respiratory failure, pulmonary embolism, and neurogenic pulmonary edema. Postoperative lung expansion strategies have been shown to be useful in prevention of the postoperative complications in surgical patients. Low tidal volume ventilation should be used in patients who develop acute respiratory distress syndrome. An antibiotic use policy should be put in practice depending on the local patterns of antimicrobial resistance in the hospital. Thromboprophylactic strategies should be used in nonambulatory patients. Meticulous attention should be paid to infection control with a special emphasis on hand-washing practices. Prevention and timely management of these complications can help to decrease the morbidity and mortality associated with pulmonary complications.

Patient safety has always been important and is a source of public concern. Recent high profile scandals and subsequent reports, such as the Francis report into the failings at Mid Staffordshire, have raised those concerns even higher. Mortality and significant morbidity associated with the practice of medicine has led to many strategies to help improve patient safety, however, with its lack of associated mortality and lower associated morbidity, dentistry has been slower at systematically considering how patient safety can be improved. Recently, several organisations, researchers and clinicians have discussed the need for a patient safety culture in dentistry. Strategies are available to help improve patient safety in healthcare and deserve further consideration in dentistry.

Patients are living longer and the rate of edentulism is decreasing. Endodontic treatment is an essential part of maintaining the health and well-being of the elderly. Retention of natural teeth improves the quality of life and the overall health and longevity of ageing patients. Also, teeth that might be otherwise extracted may be strategically valuable to retain a prosthesis, and elderly patients are more likely to have medical complications that may prevent dental extractions from being safely performed. The technical goals of endodontic treatment in the elderly are the same as those for younger patients. However, the pulpo-dentinal complex undergoes calcific changes over time, which may pose challenges for the clinician. The purposes of this review are to discuss age changes in the pulp and the challenges posed by diagnosing, treatment planning and treating the elderly endodontic patient. © 2015 Australian Dental Association.
With increasingly larger numbers of irradiated patients in our population, it seems likely that all dentists will eventually be called upon to manage the difficult problems that these patients present. Of utmost concern should be the patient's home care program and the avoidance of osteroradionecrosis. Endodontics and periodontics are the primary areas for preventing or eliminating the infection that threatens osteoradionecrosis. Endodontic treatment must be accomplished with the utmost care and maximum regard for the fragility of the periapical tissues. Pulpally involved teeth should never be left open in an irradiated patient, and extreme care must be taken with the between-visits seal. If one is called upon for preradiation evaluation, routine removal of all molar as well as other compromised teeth should be considered. Attention should be directed to the literature for further advances in the management of irradiated patients

on studies of imitative behaviour within linguistics and psychology, we argue that interactional mirroring is an important aspect of displaying implicit mentalization. We aimed to explore if, and in that case how, mirroring is displayed by general practitioners (GPs) and psychiatrists in consultations...... with patients with depression. We wanted to see how implicit mentalizing unfolds in physician–patient interactions. Consultations were videorecorded and analysed within the framework of conversation analysis. GPs and psychiatrists differed substantially in their propensity to mirror body movements and verbal...... and acoustic features of speech. GPs mirrored their patients more than psychiatrists in all modalities and were more flexible in their interactional behaviour. Psychiatrists seemed more static, regardless of the emotionality displayed by patients. Implicitly mirroring and attuning to patients could signify...

Full Text Available Several studies report autoantibody signatures in cancer. The majority of these studies analyzed adult tumors and compared the seroreactivity pattern of tumor patients with the pattern in healthy controls. Here, we compared the autoimmune response in patients with neuroblastoma and patients with Wilms tumor representing two different childhood tumors. We were able to differentiate untreated neuroblastoma patients from untreated Wilms tumor patients with an accuracy of 86.8%, a sensitivity of 87.0% and a specificity of 86.7%. The separation of treated neuroblastoma patients from treated Wilms tumor patients' yielded comparable results with an accuracy of 83.8%. We furthermore identified the antigens that contribute most to the differentiation between both tumor types. The analysis of these antigens revealed that neuroblastoma was considerably more immunogenic than Wilms tumor. The reported antigens have not been found to be relevant for comparative analyses between other tumors and controls. In summary, neuroblastoma appears as a highly immunogenic tumor as demonstrated by the extended number of antigens that separate this tumor from Wilms tumor.

Patient enrolment into clinical trials is based on oral information and informed consent, which includes an information sheet and a consent certificate. The written information should be complete, but at the same time risks being so complex that it may be questioned if a fully informed consent is possible to provide. We explored patient representatives' views and perceptions on the written trial information used in clinical cancer trials. Written patient information leaflets used in four clinical trials for colorectal cancer were used for the study. The trials included phase I-III trials, randomized and non-randomized trials that evaluated chemotherapy/targeted therapy in the neoadjuvant, adjuvant and palliative settings. Data were collected through focus groups and were analysed using inductive content analysis. Two major themes emerged: emotional responses and cognitive responses. Subthemes related to the former included individual preferences and perceptions of effect, while subthemes related to the latter were comprehensibility and layout. Based on these observations the patient representatives provided suggestions for improvement, which largely included development of future simplified and more attractive informed consent forms. The emotional and cognitive responses to written patient information reported by patient representatives provides a basis for revised formats in future trials and add to the body of information that support use of plain language, structured text and illustrations to improve the informed consent process and thereby patient enrolment into clinical trials.

To provide adequate care, medical professionals have to collect not only medical information but also information that may be related to private aspects of the patient's life. With patients' increasing awareness of information privacy, healthcare providers have to pay attention to the patients' right of privacy. This study aimed to clarify the requirements of the display method of electronic patient record (EPR) screens in consideration of both patients' information privacy concerns and health professionals' information needs. For this purpose, semi-structured group interviews were conducted of 78 medical professionals. They pointed out that partial concealment of information to meet patients' requests for privacy could result in challenges in (1) safety in healthcare, (2) information sharing, (3) collaboration, (4) hospital management, and (5) communication. They believed that EPRs should (1) meet the requirements of the therapeutic process, (2) have restricted access, (3) provide convenient access to necessary information, and (4) facilitate interprofessional collaboration. This study provides direction for the development of display methods that balance the sharing of vital information and protection of patient privacy.

Patients with chronic conditions have unique expertise that enhances interprofessional education. Although their active involvement in education is increasing, patients have minimal roles in key educational tasks. A model that brings patients and students together for patient-centred learning, with faculty playing a supportive role, has been described in theory but not yet implemented. To identify issues involved in creating an educational intervention designed and delivered by patients and document outcomes. An advisory group of community members, students and faculty guided development of the intervention (interprofessional workshops). Community educators (CEs) were recruited through community organizations with a healthcare mandate. Workshops were planned by teams of key stakeholders, delivered by CEs, and evaluated by post-workshop student questionnaires. Workshops were delivered by CEs with epilepsy, arthritis, HIV/AIDS and two groups with mental health problems. Roles and responsibilities of planning team members that facilitated control by CEs were identified. Ten workshops attended by 142 students from 15 different disciplines were all highly rated. Workshop objectives defined by CEs and student learning both closely matched dimensions of patient-centredness. Our work demonstrates feasibility and impact of an educational intervention led by patient educators facilitated but not controlled by faculty.

Positive patient identification is pivotal to several steps of the transfusion process; it is integral to ensuring that the correct blood is given to the correct patient. If patient misidentification occurs, this has potentially fatal consequences for patients. Historically patient involvement in healthcare has focused on clinical decision making, where the patient, having been provided with medical information, is encouraged to become involved in the decisions related to their individualised treatment. This article explores the aspects of patient contribution to patient safety relating to positive patient identification in transfusion. When involving patients in their care, however, clinicians must recognise the diversity of patients and the capacity of the patient to be involved. It must not be assumed that all patients will be willing or indeed able to participate. Additionally, clinicians' attitudes to patient involvement in patient safety can determine whether cultural change is successful.

There is a paucity of data to support evidence-based practices in the provision of patient/family education in the context of a new childhood cancer diagnosis. Since the majority of children with cancer are treated on pediatric oncology clinical trials, lack of effective patient/family education has the potential to negatively affect both patient and clinical trial outcomes. The Children's Oncology Group Nursing Discipline convened an interprofessional expert panel from within and beyond pediatric oncology to review available and emerging evidence and develop expert consensus recommendations regarding harmonization of patient/family education practices for newly diagnosed pediatric oncology patients across institutions. Five broad principles, with associated recommendations, were identified by the panel, including recognition that (1) in pediatric oncology, patient/family education is family-centered; (2) a diagnosis of childhood cancer is overwhelming and the family needs time to process the diagnosis and develop a plan for managing ongoing life demands before they can successfully learn to care for the child; (3) patient/family education should be an interprofessional endeavor with 3 key areas of focus: (a) diagnosis/treatment, (b) psychosocial coping, and (c) care of the child; (4) patient/family education should occur across the continuum of care; and (5) a supportive environment is necessary to optimize learning. Dissemination and implementation of these recommendations will set the stage for future studies that aim to develop evidence to inform best practices, and ultimately to establish the standard of care for effective patient/family education in pediatric oncology.
Full Text Available ABSTRACTBACKGROUNDNowadays cancer patients tend to be more involved in the medical decision process. Active participation improves health outcomes and patient satisfaction. To participate effectively patients require a huge amount of information, but time limits make it impossible to satisfy all information needs at clinics. We tried to find out which kind of media cancer patients use when searching for information and how often. Lastly, we try to find out how popular the Internet is in this regard.METODSIn this research we invited cancer patients, who had regular clinic examinations at the Oncology Institute between 21st and 25th May in 2012. We carried out a prospective research by anonymous questionnaires. We were investigating which media were used and how often. We analysed results with descriptive statistics, ANOVA, the χ²-Test and the t-test.RESULTS478 of 919 questionnaires distributed among cancer patients were returned. Mean age was 59.9 years. 61 % of responders were female, and the most common level of education was high school (33 %. Most common cancer type was breast cancer (33 %, followed by gastrointestinal and lung cancer. Patients search for information most often on television (81.4% responders, followed by specialized brochures (78%, internet (70.8% and newspapers (67.6%. Patients who do not use media for information searching are older than average (62.5 years vs. 59.9 years; p<0,000.CONCLUSIONSAccording to our results patients search for information most often on television, followed by brochures, internet and newspapers. Older patients less often search for information. This data might help doctors in everyday clinical practice.

Full Text Available Patients’ evaluation of medical care is becoming more and more important due to expanding patient-centered care. For this purpose a complex index of patient satisfaction with healthcare is used. This parameter reflects the correspondence of actual healthcare services to patient’s expectations that were formed under the influence of cultural, social, economic factors, and personal experience of each patient. Satisfaction is a subjective parameter, thus, a grade of satisfaction is barely connected with quality of healthcare services itself. Moreover, medical organizations should always take into account specific features of each patient, since they can have an influence on customer attitude to medical services.This article comprises the review of publications studying determinants of patient satisfaction. In the course of the study, we analyzed data received by research teams from different countries.According to the review, we made some conclusions. First, determinants of patient satisfaction with healthcare can be divided in two groups. The first group of factors includes patients’ characteristics such as age, gender, ethnical and cultural features. However, researches from different countries revealed that there is a difference in the importance of factors belonging to this group and their influence on satisfaction of certain patient cohorts. The second group includes factors that belong to the process of healthcare services delivery and its organization. Moreover, it was found that patient satisfaction level is changing in a waveform. Thus, medical organization should not only try to increase patient satisfaction level but also maintain it. AS a result, it necessary to monitor patient satisfaction with healthcare services. That is why there is a distinct need for the development of a new tool or adaptation of existing instrument of satisfaction measurement, which would be unitized for all medical organizations in the Russian Federation

To assess the needs of cancer patients for information about their condition and to understand the psychological impact of their illness. The discussion of prognosis and treatment options in the palliative setting is an important and difficult part of oncology practice. To evaluate this, we examined the experiences of cancer patients of the physical and psychological impact of their disease on their life, and their opinions on the communication of end-of-life decisions and treatment options. A patient questionnaire was designed that encompassed communication regarding treatment and prognosis, quality-of-life attitudes subsequent to cancer diagnosis, end-of-life care and cancer drug funding. One hundred and twenty-five patients with a diagnosis of cancer were asked to participate and 96 questionnaires were completed and available for analysis. The questionnaire consisted of 63 questions and was completed in both an inpatient and outpatient setting. This survey brought to light a number of controversial issues in cancer service provision, highlighting the emotional and psychological changes brought about by a cancer diagnosis. Major concerns of our patients include fear of death and pain, changes in interpersonal relationships and financial constraints. Only 66% of the patients wanted to be given a prognosis by their clinicians and just 70% of the patients recalled being given a detailed prognosis. 11% of the patients were not prepared to undergo palliative treatment. In all, 7% were not prepared to accept treatment for 1 year and 2% for 5 years of life in exchange for the potential side effects of cytotoxic chemotherapy. 12% of the patients would not want to be in possession of the information that they were in the terminal phase of the illness with a short time to live and 16% would not want this discussed with their next of kin. This study informs medical professionals about the importance of tailoring information to the needs of the individual patient, and we

In an emerging competitive market such as healthcare, managers should focus on achieving excellent ratings to distinguish their organization from others. When it comes to customer loyalty, "excellent" has a different meaning. Customers who are merely satisfied often do not come back. The purpose of this study was to find out what influences adult patients to rate their overall experience as "excellent." The study used patient satisfaction data collected from one major academic hospital and four community hospitals. After conducting a multiple logistic regression analysis, certain attributes were shown to be more likely than others to influence patients to rate their experiences as excellent. The study revealed that staff care is the most influential attribute, followed by nursing care. These two attributes are distinctively stronger drivers of overall satisfaction than are the other attributes studied (i.e., physician care, admission process, room, and food). Staff care and nursing care are under the control of healthcare managers. If improvements are needed, they can be accomplished through training programs such as total quality management or continuous quality improvement, through which staff employees and nurses learn to be sensitive to patients' needs. Satisfying patients' needs is the first step toward having loyal patients, so hospitals that strive to ensure their patients are completely satisfied are more likely to prosper.
Healthcare industry continues to evolve under conditions of intense competition in approaching health prevention, protection, and promotion. Therefore, healthcare providers are challenged to always ensure better patient experience, winning patients’ satisfaction, and loyalty and remain competitive on today’s healthcare market. Healthcare markets bring together professionals and their patients into real collaborative relationships, which empower patients to contribute to the healthcare improvement. Within this competitive landscape, which is also characterized by digital health tools boosting patients’ awareness and controlling their own health, medical providers need to be perceived as skilled and trustworthy in relying on patients’ needs, expectations, and sacrifices are required in order to obtain the promised benefits. Moreover, while constantly providing a holistic assessment of the healthcare services’ and experience attributes, acting on feedback and reaching healthcare service excellence, providing a better understanding of all the touch points with their patients and improving the quality and consistency of all these touch points, all these are achieved by employees, who are truly connected to the healthcare business. Today, patients are systematically becoming aware of the diversity of their choices, being increasingly involved in making better healthcare choices, and, so, more and more innovative products are introduced, targeting new patient segments. Findings from the last three years have shown that patients may achieve better outcomes due to the stakeholders’ commitment to innovation within the context of the big-data revolution, by building new values.

Full Text Available Hypertension is one of the most common vascular diseases. The brain as target organs in hypertension is damaged more often and earlier. Neurological complications due to hypertension are frequently hyperdiagnosed in Russian neurological practice. Thus, headache, dizziness, impaired recall of recent events, nocturnal sleep disorders, and many other complaints in a hypertensive patient are usually regarded as a manifestation of dyscirculatory encephalopathy. At the same time headaches (tension headache and migraine in hypertensive patients are predominantly primary; headache associated with dramatic marked elevations in blood pressure is encountered in only a small number of patients. The role of cerebrovascular diseases in the development of dizziness in hypertensive patients is also overestimated. The vast majority of cases, patients with this complaint are in fact identified to have benign paroxysmal postural vertigo, Mеniеre’s disease, vestibular neuronitis, or vestibular migraine. Psychogenic disorders or multisensory insufficiency are generally responsible for non-systemic vertigo in hypertensive patients. Chronic cerebral circulatory insufficiency may cause non-systemic vertigo as a subjective equivalent of postural instability.Cognitive impairments (CIs are the most common and earliest manifestation of cerebrovascular lesion in hypertension. In most cases, CIs in hypertension were vascular and associated with cerebrovascular lesion due to lacunar infarcts and leukoaraiosis. However, mixed CIs frequently occur when hypertensive patients are also found to have signs of a degenerative disease, most commonly in Alzheimer’s disease.

In this current economic climate where the costs of providing a good medical service are escalating, patients are demanding a higher level of service from the Radiation Oncology providers. This coupled with the rising level of patients' expectations make it absolutely paramount for Radiation Oncology providers to offer the best possible service to their patients. In order to do this, it is essential to assess the present level of patient satisfaction prior to deciding which aspects of the current service need to be changed. In this pilot study, we assess the level of patient satisfaction with aspects of the radiotherapy service and the level of patient anxiety both prior to and following radiotherapy at the Perth Radiation Oncology Centre. A questionnaire was created using a combination of the Information Satisfaction Questionnaire-1 (ISQ-1), the Very Short Questionnaire 9 (VSQ 9) and the State Trait Anxiety Index (STAI). One hundred new patients were studied, all of whom were to have radiotherapy with curative intent. The results of this study are reviewed in this presentation

Full Text Available Human papillomavirus (HPV infection is the most common sexually transmitted disease worldwide and can result in pre-malignancies or overt malignancies of the skin and mucosal surfaces. HPV-related illnesses are an important personal and public health problem causing physical, mental, sexual and financial detriments. Moreover, this set of malignancies severely affects the immunosuppressed population, particularly HIV-positive patients and organ-transplant recipients. There is growing incidence of HPV-associated anogenital malignancies as well as a decrease in the average age of affected patients, likely related to the rising number of high-risk individuals. Squamous cell carcinoma is the most common type of HPV-related malignancy. Current treatment options for HPV infection and subsequent disease manifestations include imiquimod, retinoids, intralesional bleomycin, and cidofovir; however, primary prevention with HPV vaccination remains the most effective strategy. This review will discuss anogenital lesions in immunocompromised patients, cutaneous warts at nongenital sites, the association of HPV with skin cancer in immunocompromised patients, warts and carcinomas in organ-transplant patients, HIV-positive patients with HPV infections, and the management of cutaneous disease in the immunocompromised patient.

BACKGROUND: During the second half of the 20th century, the literature on the doctor-patient relationship mainly dealt with the management of "difficult" (personality-disordered) patients. Similar problems, however, surround other types of "special" patients. METHOD: An overview and analysis of the literature were conducted. As a result, such patients can be subcategorized by their main presentations; each requires a specific management strategy. RESULTS: Three types of "special" patients stir up irrational feelings in their caregivers. Sick celebrities threaten to focus public scrutiny on the private world of medical caregivers. VIPs generate awe in caregivers, with loss of the objectivity essential to the practice of scientific medicine. Potentates unearth narcissism in the caregiver-patient relationship, which triggers a struggle between power and shame. Pride, privacy, and the staff's need to be in control are all threatened by introduction of the special patient into medicine's closed culture. CONCLUSION: The privacy that is owed to sick celebrities should be extended to protect overexposed staff. The awe and loss of medical objectivity that VIPs generate are counteracted by team leadership dedicated to avoiding any deviation from standard clinical procedure. Moreover, the collective ill will surrounding potentates can be neutralized by reassuring them that they are "special"-and by caregivers mending their own vulnerable self-esteem.

Personality and coping mechanisms are related to patients' perceptions of their tinnitus. Although the occurrence of tinnitus is not unusual, its nature varies from infrequent, barely noticeable sound to an unrelenting, absorbing disturbance of critical significance. Tinnitus is a subjective complaint: the same level of tinnitus may be described by one patient as intolerable and by another as barely noticeable. Stress is intricately related to tinnitus: persons with severe tinnitus experience excessive stress. This has debilitating effects on their defences and coping can become very difficult. Patients may demonstrate a cluster of hysterical defences or a serious degree of depression. Many tinnitus patients focus on their problem, objectifying it and thus intensifying the disturbance. Most tinnitus patients can be helped by psychological intervention. A small percentage of tinnitus patients can be classified as disturbed, with borderline personalities. These patients are usually not suitable for therapy or biofeedback training. Tinnitus can be stress-related disorder. As a person is faced with conflict, physiological changes occur as a result of the "fight or flight" reaction. This state of stress can be responsible for the onset or exacerbation of a tinnitus episode. Treatment by management of stress can be successful, promoting relief through a shift of focus, repose from a state of tension, and support of constructive defences.

The therapeutic management of patients with osteoarthritis aims to decrease pain and inflammation, improve physical function, and to apply safe and effective treatments. A patient-centered approach implies the active participation of the patient in the design of the treatment plan and in timely and informed decision-making at all stages of the disease. The nucleus of treatment is patient education, physical activity and therapeutic exercise, together with weight control in overweight or obese patients. Self-care by the individual and by the family is fundamental in day-to-day patient management. The use of physical therapies, technical aids (walking sticks, etc.) and simple analgesics, opium alkaloids, and antiinflammatory drugs have demonstrated effectiveness in controlling pain, improving physical function and quality of life and their use is clearly indicated in the treatment of osteoarthritis. Conservative surgery and joint replacement is indicated when treatment goals are not achieved in specific patients. Copyright © 2014 Elsevier España, S.L. All rights reserved.

The way that health care providers feel, both within themselves and toward their patients, may influence their clinical performance and impact patient safety, yet this aspect of provider behavior has received relatively little attention. How providers feel, their emotional or affective state, may exert a significant, unintended influence on their patients, and may compromise safety. We examined a broad literature across multiple disciplines to review the interrelationships between emotion, decision making, and behavior, and to assess their potential impact on patient safety. There is abundant evidence that the emotional state of the health care provider may be influenced by factors including characteristics of the patient, ambient conditions in the health care setting, diurnal, circadian, infradian, and seasonal variables, as well as endogenous disorders of the individual provider. These influences may lead to affective biases in decision making, resulting in errors and adverse events. Clinical reasoning and judgment may be particularly susceptible to emotional influence, especially those processes that rely on intuitive judgments. There are many ways that the emotional state of the health care provider can influence patient care. To reduce emotional errors, the level of awareness of these factors should be raised. Emotional skills training should be incorporated into the education of health care professionals. Specifically, clinical teaching should promote more openness and discussion about the provider's feelings toward patients. Strategies should be developed to help providers identify and de-bias themselves against emotional influences that may impact care, particularly in the emotionally evocative patient. Psychiatric conditions within the provider, which may compromise patient safety, need to be promptly detected, diagnosed, and managed.

Desmoids are rare tumors of the connective tissue. It develops about 1:1000 times more in patients with familial adenomatous polyposis (FAP, Gardner syndrome) compared to normal population. It has been shown in molecular genetic examinations, that different mutations of the APC gene are responsible for desmoid tumors in FAP. It means, that this disease is one of the extraintestinal manifestations of Gardner syndrome. This tumor has high recurrence rate and is growing rapidly, and as a result it is the second most common cause of death in FAP patients. That is why genetic examination for FAP patients is advised to decide if the patient has higher risk for desmoid formation. If the result of the genetic test is positive, it is advisable to try to slow the progression of polyposis with medical treatment, and so to delay the date of the colectomy because the surgical intervention--and connective tissue damage--can induce desmoid formation in these patients. At the same time it is reasonable to examine and regularly control patients with sporadic desmoid tumors searching for other manifestations of Gardner syndrome (colon, stomach and duodenum polyposis, tumor of papilla Vateri, retinopathy, etc.). Palliative surgery is not indicated in patients with inoperable intraabdominal desmoid tumors, because partial resections (R1, R2, debulking) result in further tumor progression. In these patients medical treatment (sulindac, tamoxifen), chemotherapy (doxorubicin, dacarbazin) and radiotherapy or combination of them can result tumor remission. We describe our three patients (an abdominal wall desmoid four years following Cesarean section; a desmoid tumor in the retroperitoneum and in the pelvis diagnosed three years after total colectomy; and a retroperitoneal and abdominal wall desmoid one year after total colectomy) and etiology, diagnosis and therapy of desmoid tumors are discussed.

Full Text Available Abstract Background: To determine the number of patients with narcolepsy in Slovenia, describe their typical clinical features and the diagnostic criteria they met on polysomnography (PSG, the mean sleep latency test (MSLT and HLA typing.Methods: Retrospective study of all narcolepsy patients referred to the National Sleep Disorder Centre at the Institute of Clinical Neurophysiology, University Medical Centre Ljubljana in the period from May 1994 to September 2013.Results: There are currently only 38 patients with narcolepsy in Slovenia. The average time lapse from onset to diagnosis is 17 years. The time lapse is much longer for older patients. The prevalence of narcolepsy in Slovenia is 1.85 to 100,000 inhabitants. All patients had EDS, 89% cataplexy, 66% hallucinations and 37% sleep paralysis at the time of diagnosis. Characteristic changes on PSG and MSLT were present in 97% of all tested patients. HLA DQB1*0602 is present in 88% of all tested patients. The most common differential diagnoses found were OSAS and hypersomnia.Conclusion: With a prevalence of 1.85/100,000 narcolepsy in Slovenia, it is seriously underdiagnosed and not recognized by general practitioners and neurologists alike. Both should be more aware of the disease and think about the possibility of it in patients with excessive daytime sleepiness and unexplained attacks, with additional symptoms such as hallucinations and paralysis during sleep. Such patients should be sent to the Sleep Disorder Centre, where the diagnosis can be confirmed and treatment started as soon as possible, thereby reducing the patient’s pathological symptoms and improve their quality of life.

Effective communication is important for the delivery of quality care. The Emergency Department (ED) environment poses significant challenges to effective communication. The objective of this study was to determine patients' perceptions of their ED team's communication skills. This was a cross-sectional study in an urban, academic ED. Patients completed the Communication Assessment Tool for Teams (CAT-T) survey upon ED exit. The CAT-T was adapted from the psychometrically validated Communication Assessment Tool (CAT) to measure patient perceptions of communication with a medical team. The 14 core CAT-T items are associated with a 5-point scale (5 = excellent); results are reported as the percent of participants who responded "excellent." Responses were analyzed for differences based on age, sex, race, and operational metrics (wait time, ED daily census). There were 346 patients identified; the final sample for analysis was 226 patients (53.5% female, 48.2% Caucasian), representing a response rate of 65.3%. The scores on CAT-T items (reported as % "excellent") ranged from 50.0% to 76.1%. The highest-scoring items were "let me talk without interruptions" (76.1%), "talked in terms I could understand" (75.2%), and "treated me with respect" (74.3%). The lowest-scoring item was "encouraged me to ask questions" (50.0%). No differences were noted based on patient sex, race, age, wait time, or daily census of the ED. The patients in this study perceived that the ED teams were respectful and allowed them to talk without interruptions; however, lower ratings were given for items related to actively engaging the patient in decision-making and asking questions.

Computer simulation methods for determining patient dose from dental radiography have demonstrated that patient risk from a two-film interproximal examination ranges from 1.1 X 10(-8) to 3.4 X 10(-7) using 90-kVp beams, depending on film speed, projection technique, and age and sex of the patient. Further, changing from a short-cone round-beam to a long-cone technique with rectangular collimation reduces risk by a factor of 2.9, independent of other factors
When we say "medical ethics" we understand the responsibility of the physician for his medical education and his attitude to his patient. But Hippocrates is known to have said that the efficiency and good results of the treatment depends not only on the physician but on the patient and his engagement, his observance of the doctors' advice, his attitude to his own psyche and body, both in health as in illness. This is an ethical problem known to every practitioner, the problem of ethics of the patient, which ought to be more widely disseminated in society.

A study was made of the influence of the constant MKM2-1 magnets on patients suffering from essential hypertension. Continuous action of the magnetic field, created by such magnets, on the patients with stage II essential hypertension was noted to result in a decrease of arterial pressure without the occurrence of any side effects and in a simultaneous reduction of the scope of drug administration. Apart from that fact, magnetotherapy was discovered to produce a beneficial effect on the central hemodynamics and microcirculation. The use of the MKM2-1 magnets may be regarded as a feasible method of the treatment of essential hypertension patients at any medical institution.

The value of the arts and humanities in becoming an "educated" pharmacist is reviewed in this commentary. The term "patient care literacy" is defined as becoming a more humane pharmacist. This implies not only using heads but HARTSS (humanities, arts and social sciences) for developing the necessary skills. A conceptual framework for curricular reform that focuses on using the arts and humanities is proposed for advancing patient care literacy. Methods for enhancing use of arts and humanities for developing pharmacy graduates is specifically proposed. The need for more empiric research to demonstrate the value of the arts and humanities in developing a patient care literate professional is highlighted.

Reasons for the variation in patient doses from chest radiography procedure were investigated by assessing entrance skin doses from kerma-area product measurements. Data were collected from seven x-ray tubes in five hospitals involving 259 adult patients. The third quartile value was 0.81 mGy compared to general reference level of 0.30 mGy. The applied tube potential was main contributor to patient dose variation. If department use at least 90 k Vp, the mean entrance surface dose would be reduced ut to factor six. Modification of departmental procedure is correct approach for dose reduction in diagnostic radiology. (author) [sr
Full Text Available Introduction. One of the characteristic signs of uremic syndrome is anemia. One of major factors that affects on severity of anemia in ESRD is underlying diseas. The porpuse of this study is to compaire anemia between diabetic and non diabetic ESRD patients. Methods. In a case control study we compared the mean valuse of Hb, Het, MCV, MCH, MCHC, BUN, Cr and duration of dialysis between diabetic and nondiabetic patients on chronic hemodialyis. some variables (such as age, sex, use of erythropoietin, nonderolone decaonats, folic acid, ferrous sulfate, transfusion and blood loss in recent three months and acquired kidney cysts were matched between cases and controls. Results. Means of Hb were 9±1.3 and 8 ± 1.7 in diabetic and non diabetic patients (P<0.05. Mean corposcular volume in diabetic patients (91±3.1 fl was more higher than non diabetic ones (87.1 ± 8.9 (P < 0.05. Other indices had no differences between two groups (P > 0.05. Discussion. Severity of anemia in patients with diabetic nephropathy is milder that other patients with ESRD. So, Anemia as an indicator of chronocity of renal disease in diabetics is missleading.

As an aid to predicting future hospital admissions, we compare use of the Multinomial Logit and the Utility Maximising Nested Logit models to describe how patients choose their hospitals. The models are fitted to real data from Derbyshire, United Kingdom, which lists the postcodes of more than 200,000 admissions to six different local hospitals. Both elective and emergency admissions are analysed for this mixed urban/rural area. For characteristics that may affect a patient's choice of hospital, we consider the distance of the patient from the hospital, the number of beds at the hospital and the number of car parking spaces available at the hospital, as well as several statistics publicly available on National Health Service (NHS) websites: an average waiting time, the patient survey score for ward cleanliness, the patient safety score and the inpatient survey score for overall care. The Multinomial Logit model is successfully fitted to the data. Results obtained with the Utility Maximising Nested Logit model show that nesting according to city or town may be invalid for these data; in other words, the choice of hospital does not appear to be preceded by choice of city. In all of the analysis carried out, distance appears to be one of the main influences on a patient's choice of hospital rather than statistics available on the Internet.

Prior research on the use of patients as teachers has focused on testing the effectiveness of this practice and exploring its benefits for students. However, very little is known about the added value of patient teaching and how it relates to patient-centred learning. The aim of this study was to explore whether there is added value in using patients as instructors in health professions education and, if there is, to examine how it is constituted. Group interviews were conducted with physiotherapy and occupational therapy students who had attended a 3-hour optional class entitled 'Thoughtful joint examination and respectful patient contact'. This class was delivered by patient-instructors (PIs), who were patients with rheumatism certified to teach. A semi-structured interview guide was used. Interviews continued until data saturation occurred (seven interviews). The interviews were recorded and transcribed verbatim. Data were analysed using content analysis. The main finding of this study is that PI sessions facilitate a learning environment in which the content matter is complemented by the provision of realism and individual perspectives on rheumatism, the pedagogical format is characterised by authenticity and intimacy in the style of instruction and feedback, and the PI-student relationship is characterised by balanced teacher-student power relations that support the legitimacy of learning and make space for the asking of questions and the making of mistakes. This study indicates that, in terms of power relations, the PI-student relationship differs from those between faculty teachers and students, and students and patients in the clinic. The formation of a professional identity by students may clash with the fulfilment of their learning tasks in the clinical environment. The study indicates that patient-centredness can be fostered in the PI-student relationship. This is probably supported by the absence of faculty staff involvement in PI teaching sessions

The radiological findings of eight patients with the acquired immunodeficiency syndrome (AIDS) who developed bone lesions were analyzed in conjunction with twelve similar published cases. Our series included three patients with lymphoma, two with bacillary angiomatosis, two with tuberculosis and one with staphylococcal osteomyelitis. All the lesions were lithic regardless of the etiology. Both in our cases and in those previously published bone repair was only seen in cases of bacillary angiomatosis treated with erythromycin. No pathognomonic findings were observed. However, the association of skin and bone lesions in immuno deficient patients should always bring the consideration of bacillary angiomatosis in the differential diagnosis. This is particularly relevant since this a condition amenable to treatment once correctly identified. The radiological findings in the lymphoma and tuberculosis patients have not been described previously. (author). 9 refs., 7 figs., 3 tabs

The purpose of this descriptive pilot study was two-fold: (a) to test psychometrically an observational instrument designed to measure patient behaviors displayed while unrestrained and receiving a musical intervention; and (b) to determine the effect of a musical intervention on the behavioral reactions of physically restrained patients. The Restraint-Music Response Instrument (RMRI) is a 40-item observational checklist consisting of 22 positive and 18 negative responses developed by the researchers. Content validity was assessed by a panel of experts. The RMRI was tested for interrater reliability using three simulated and 10 actual patients. Results suggest that the RMRI is a valid and reliable measure of patients' responses to music but requires additional study with a control group not receiving the intervention.

A white female patient presented to the university clinic to obtain implant retained prostheses. She had an edentulous maxillary jaw and presented three teeth with poor prognosis (33, 34 and 43). The alveolar bone and the surrounding tissues were healthy. The patient did not report any relevant medical history contraindicating routine dental treatment or implant surgery, but self-reported a dental history of asymptomatic nocturnal bruxism. The treatment plan was set and two Branemark protocols supported by six implants in each arch were installed after a 6-month healing period. A soft occlusal splint was made due to the patient's history of bruxism, and the lack of its use by the patient resulted in an acrylic fracture. The prosthesis was repaired and the importance of using the occlusal splint was restated. In the 4-year follow-up no fractures were reported. PMID:24907215

Legislation requires the healthcare industry to directly engage patients through technology. This paper proposes a model that can be used to review hospital websites for features that engage patients in their healthcare. The model describes four levels of patient engagement in website design. The sample consisted of 130 hospital websites from hospitals listed on 2010 and 2011 Most Wired Hospitals. Hospital websites were analyzed for features that encouraged patient interaction with their healthcare according to the levels in the model. Of the four levels identified in the model, websites ranged from "informing" to "collaborative" in website design. There was great variation of features offered on hospital websites with few being engaging and interactive. © 2012 National Association for Healthcare Quality.

The majority of the Swiss population uses the internet to seek information about health. The objective is to be better informed, before or after the consultation. Doctors can advise their information-seeking patients about high quality websites, be it medical portals or websites dedicated to a specific pathology. Doctors should not see the internet as a threat but rather as an opportunity to strengthen the doctor-patient relationship.

Tobacco smoking is the main cause of COPD. Smoking cessation is the only therapeutic measure that can cure COPD and prevent this disorder from its chronic progression. Smoking cessation in COPD patients is difficult because most of these patients have specific characteristics that prevent them to quit. Recently, an ERS Task Force has developed a Consensus Document that contains recommendations for helping COPD smokers to quit.

Full Text Available ABSTRACT BACKGROUND: Dysphagia is described as a complaint in 32% of patients with laryngitis. OBJECTIVE: The objective of this investigation was to evaluate oral and pharyngeal transit of patients with laryngitis, with the hypothesis that alteration in oral-pharyngeal bolus transit may be involved with dysphagia. METHODS: Videofluoroscopic evaluation of the swallowing of liquid, paste and solid boluses was performed in 21 patients with laryngitis, 10 of them with dysphagia, and 21 normal volunteers of the same age and sex. Two swallows of 5 mL liquid bolus, two swallows of 5 mL paste bolus and two swallows of a solid bolus were evaluated in a random sequence. The liquid bolus was 100% liquid barium sulfate and the paste bolus was prepared with 50 mL of liquid barium and 4 g of food thickener (starch and maltodextrin. The solid bolus was a soft 2.2 g cookie coated with liquid barium. Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. RESULTS: The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers. Patients with laryngitis and dysphagia had longer preparation for paste and solid boluses, and a faster oral transit time with liquid, paste and solid boluses. CONCLUSION: A longer oral preparation for paste and solid boluses and a faster transit through the mouth are associated with dysphagia in patients with laryngitis.

Because of their longer life expectancy, the risk of late manifestations of detrimental radiation effects is greater in children than in adults and, consequently, paediatric radiology gives ground for more concern regarding radiation protection than radiology of adults. The purpose of our study was to assess, in terms of effective dose, the magnitude of paediatric patient exposure during conventional X-ray examinations, selected for their high frequency or their relatively high doses delivered to patient
Full Text Available Stroke is one of the major problems in medical and healthcare that can cause severe disability and death of patients especially for older population. Rehabilitation plays an important role in stroke therapy. However, most of the rehabilitative exercises are monotonous and tiring for the patients. For a particular time, they can easily get bored in doing these exercises. The role of patient’s motivation in rehabilitation is vital. Motivation and rehabilitative outcomes are strongly related. Digital games promise to help stroke patients to feel motivated and more engaged in rehabilitative training through motivational gameplay. Most of the commercial games available in the market are not well-designed for stroke patients and their motivational needs in rehabilitation. This study aims at understanding the motivational requirements of stroke patients in doing rehabilitative exercises and living in a post-stroke life. Based on the findings from the literature review, we report factors that can influence the stroke patients’ level of motivation such as social functioning, patient-therapist relationship, goal-setting, and music. These findings are insightful and useful for ideating and designing interactive motivation-driven games for stroke patients. The motivational factors of stroke patients in rehabilitation may help the game designers to design motivation-driven game contexts, contents, and gameplay. Moreover, these findings may also help healthcare professionals who concern stroke patient’s motivation in rehabilitative context. In this paper, we reported our Virtual Nursing Home (VNH concept and the games that we are currently developing and re-designing. Based on this literature review, we will present and test out the ideas how we can integrate these motivational factors in our future game design, development, and enhancement.

Changes in the delivery of health care services in the United States are proceeding so rapidly that many providers are asking how the working relationships between doctors and patients will be effected. Accelerated by cost containment, quality improvement and the growth of managed care, these changes have caused some critics to feel that shorter visits and gatekeeper systems will promote an adversarial relationship between physicians and patients. However, proponents of the changing system feel that better prevention, follow-up care and the attention to customer service these plans can offer will lead to increased patient satisfaction and improved doctor-patient communication. Dedicated to addressing these concerns, the Bayer Institute for Health Care Communication was established in 1987 as a continuing medical education program (CME) focusing on this topic. A half-day workshop on clinician-patient communication to enhance health outcomes was introduced in 1992 and a second workshop, "Difficult' Clinician-Patient Relationships," was developed two years later. The two courses discussed in this article are offered to all physicians, residents, medical students, mid-level providers and other interested staff within the Carle system.

Current literature on dental radiology was reviewed in order to seek justification for radiological protection of patients in dental radiography, to explore the different factors affecting patient dose and to derive practical guidance on how to achieve radiological protection of patients in dentistry. Individual doses incurred in dental radiology are in general relatively low, however it is generally accepted that there is no safe level of radiation dose and that no matter how low the doses received are, there is a mathematical probability of an effect. Hence appropriate patient protection measures must be instituted to keep the exposures as low as reasonably achievable (ALARA). The literature review demonstrated that there is considerable scope for significant dose reductions in dental radiology using the techniques of optimisation of protection. The techniques of optimization of protection that can be used to ensure patient dose is as low as reasonably achievable whilst achieving clinically adequate image quality include the following: image receptor selection, image receptor holders, collimation, beam filtration, operating potential and exposure time, patient protective equipment, film exposure and processing, film storage, image viewing, quality assurance, diagnostic reference levels, technique charts and training and education.(au)

Concurrent chemoradiotherapy for cancer of head and neck is becoming more popular as the treatment of choice. It is considered to maintain the quality of life (QOL) of patients better than operative treatments in terms of preserving the functions, organs, and figure, but recently we cannot necessarily say that it maintains the QOL of patients better than operative treatments because its complications after therapy disturb daily life. We report the results of a questionnaire survey about complications after therapy, problems during therapy, improvements, and satisfaction level directed at patients with cancer of the head and neck who received Concurrent chemoradiotherapy for the purpose of ascertaining if patients can actually maintain their QOL after therapy. As a result, the most controversial problem was mouth dryness, but the symptom improved as the follow-up duration got longer. As for the satisfaction level, 'very-satisfied' and 'almost-satisfied' were more than 90%, so we concluded that the QOL of patients is maintained after therapy, while there are still improvements to be made. We also concluded that we should continue to make improvement and try to improve the QOL of patients during and after therapy. (author)

Morphological imaging, based on the use of various techniques including ultrasound, X-ray computed tomography (CT), and magnetic resonance imaging (MRI), plays an important role in the characterization, diagnosis and follow-up of patients with Human Immunodeficiency Virus (HIV) infection and Acquired Immunodeficiency Syndrome (AIDS). While the presence of thoracic infections, the most frequently observed illnesses in AIDS patients, can best be performed by using conventional chest films and CT, the assessment of cerebral involvement in AIDS patients - characterized by the presence of focal masses, demyelination, meningitis, and infarction - is best achieved using MRI. The work-up of patients with gastrointestinal symptoms should include the use of ultrasound for the evaluation of visceral involvement and lymphadenopathy, completed by CT to further characterize pathologic conditions in either the bowel or visceral organs. Ultrasound is the screening exam of choice in AIDS patients with suspected renal disease, but other methods may be necessary for the assessment of the complications due to pharmacological treatment. Musculoskeletal complications may require the combined use of all the above methods, since they may be caused by infections, tumors and rheumatologic illness. The use of the radiographic methods for the detection of the numerous forms of infections and malignancies in AIDS patients is described in detail for the various body districts

The principal postulate of the neurophysiological model of tinnitus is that all levels of the auditory pathways and several nonauditory systems play essential roles in each case of tinnitus, stressing the dominance of nonauditory systems in determining the level of tinnitus annoyance. Thus it has been proposed to treat tinnitus by inducing and facilitating habituation to the tinnitus signal. The goal is to reach the stage at which, although patients may perceive tinnitus as unchanged when they focus on it, they are otherwise not aware of tinnitus. Furthermore, even when perceived, tinnitus does not evoke annoyance. Habituation is achieved by directive counseling combined with low-level, broad-band noise generated by wearable generators, and environmental sounds, according to a specific protocol. For habituation to occur, it is imperative to avoid masking tinnitus by these sounds. Since 1991, > 500 tinnitus patients have been seen in our center. About 40% exhibited hyperacusis to varying degrees. A survey of > 100 patients revealed > 80% of significant improvement in groups of patients treated with the full protocol involving counseling and the use of noise generators. Notably, in patients who received counseling only, the success rate was < 20%. The improvement in hyperacusis was observed in approximately 90% of treated patients.

Nutritional support plays an important role in the treatment of patients with burns. Due to the severe hypercatabolism that develops in these patients, oral support is insufficient in most cases, and this makes it essential to initiate artificial nutritional support (either enteral or parenteral). Enteral nutrition is more physiological than parenteral, and data exist which show that in patients with burns, enteral nutrition exercises a protective effect on the intestine and may even reduce the hypermetabolic response in these patients. The purpose of the study was to evaluate the effectiveness and tolerance of enteral nutritional support with a hypercaloric, hyperproteic diet with a high content of branched amino acids in the nutritional support of patients suffering from burns. The study included 12 patients (8 males and 4 females), admitted to the Burns Unit. Average age was 35 +/- 17 years (range: 21-85 years). The percentage of body surface affected by the burns was 10% in two cases, between 10-30% in three cases, between 30-50% in five cases and over 50% in two cases. Initiation of the enteral nutrition was between twenty-four hours and seven days after the burn. The patients were kept in the unit until they were discharged, and the average time spent in the unit was 31.5 days (range: 17-63 days). Total energetic requirements were calculated based on Harris-Benedict, with a variable aggression factor depending on the body surface burned, which varied from 2,000 and 4,000 cal day. Nitrogenous balance was determined on a daily basis, and plasmatic levels of total proteins, albumin and prealbumin on a weekly basis. There was a significant difference between the prealbumin values at the initiation and finalization of the enteral nutrition (9.6 +/- 2.24 mg/dl compared with 19.75 +/- 5.48 mg/dl; p diet was very good, and only mild complications such as diarrhoea developed in two patients.

The present paper revisits the ethical models of patient--physician relationship from the perspective of patient autonomy and values. It seems that the four traditional models of physician--patient relationship proposed by Emanuel & Emanuel in 1992 closely link patient values and patient autonomy. On the other hand, their reinterpretation provided by Agarwal & Murinson twenty years later emphasizes the independent expression of values and autonomy in individual patients. Additionally, patient education has been assumed to join patient values and patient autonomy. Moreover, several authors have noted that, over the past few decades, patient autonomy has gradually replaced the paternalistic approach based on the premise that the physician knows what is best for the patient. Neither the paternalistic model of physician-patient relationship, nor the informative model is considered to be satisfactory, as the paternalistic model excludes patient values from decision making, while the informative model excludes physician values from decision making. However, the deliberative model of patient-physician interaction represents an adequate alternative to the two unsatisfactory approaches by promoting shared decision making between the physician and the patient. It has also been suggested that the deliberative model would be ideal for exercising patient autonomy in chronic care and that the ethical role of patient education would be to make the deliberative model applicable to chronic care. In this regard, studies have indicated that the use of decision support interventions might increase the deliberative capacity of chronic patients.

Full text: Boron Neutron Capture Therapy (BNCT) is a technique that selectively targets cancer cells while sparing normal tissues by virtue of the differential uptake of a 10 B carrier compound in tumor. The National Atomic Energy Commission (CNEA) and the Oncology Institute 'Angel H. Roffo' (IOAR) began a BNCT programme in 2003 for treating cutaneous skin melanomas in extremities. The neutron beam used is the hyperthermal one developed at the RA-6 Reactor of the Bariloche Atomic Centre (CAB). The prescribed dose is delivered in one fraction and therefore patient positioning and knowledge of the dose received by normal tissue are crucial. 10 irradiations have been done since 2003, all of them in legs and feet and the dose prescription was determined by the maximum tolerable skin dose. Due to the characteristics of this treatment the patient body might be exposed not only to the primary beam but also to the secondary photon beam produced by neutron capture at the target itself. Thus a patient radiation-monitoring plan was implemented in order to evaluate the gamma dose delivered to sensible organs of each patient. An acrylic water-filled whole body phantom was used for preliminary gamma dose and thermal neutron flux measurements at positions related to patient's body sensible organs considering tentative patient positions. The beam port shielding was, in this way, optimized. TLD-700 and Manganese foils were used for gamma and thermal neutron detection. The TLD-700 thermal neutron response was previously evaluated by using the in-phantom beam dosimetry characterization. In-vivo dosimetry with TLD is routinely implemented in order to evaluate gamma dose to sensible organs of each patient. These organs are chosen depending on its distance from the zone to be irradiated and its radio-sensibility. All TLDs have been positioned well outside the irradiation field. Maximum gamma dose received outside the radiation field in healthy tissues was well below tolerance dose for
Full Text Available Objectives. The incidence of cancer among the indigenous Sami people of Northern Finland is lower than among the Finnish general population. The survival of Sami cancer patients is not known, and therefore it is the object of this study. Study design. The cohort consisted of 2,091 Sami and 4,161 non-Sami who lived on 31 December 1978 in the two Sami municipalities of Inari and Utsjoki, which are located in Northern Finland and are 300–500 km away from the nearest central hospital. The survival experience of Sami and non-Sami cancer patients diagnosed in this cohort during 1979–2009 was compared with that of the Finnish patients outside the cohort. Methods. The Sami and non-Sami cancer patients were matched to other Finnish cancer patients for gender, age and year of diagnosis and for the site of cancer. An additional matching was done for the stage at diagnosis. Cancer-specific survival analyses were made using the Kaplan–Meier method and Cox regression modelling. Results. There were 204 Sami and 391 non-Sami cancer cases in the cohort, 20,181 matched controls without matching with stage, and 7,874 stage-matched controls. In the cancer-specific analysis without stage variable, the hazard ratio for Sami was 1.05 (95% confidence interval 0.85–1.30 and for non-Sami 1.02 (0.86–1.20, indicating no difference between the survival of those groups and other patients in Finland. Likewise, when the same was done by also matching the stage, there was no difference in cancer survival. Conclusion. Long distances to medical care or Sami ethnicity have no influence on the cancer patient survival in Northern Finland.

Otorhinolaryngology (ORL) is considered a specialty associated with few serious patient injuries. Research data that support this belief are, however, scarce. We analyzed claims associated with ORL to determine the number of Finnish cases and the possible common denominators. Register study of ORL cases in the Patient Insurance Centre (PIC), the Regional State Administrative Agencies (RSAA), and the National Supervisory Authority for Welfare and Care (Valvira) during the years 2004 to 2008. These three agencies are the main actors in the field of patient injury in Finland. We analyzed compensated ORL patient injury cases from the PIC and cases associated with the ORL specialty for Valvira and RSAA from 2004 to 2008 and surveyed patient treatment files, statements from specialists, and compensation decisions. Injuries were usually associated with operations; three patients who experienced injuries during these procedures died. Common ORL operations such as tonsillectomy, septoplasty, and paranasal sinus surgery were most often associated with compensated injuries. Serious injuries were few, with a total of 110 out of 422 (26.1%) claims compensated by the PIC. Of the 110 compensated cases, 30 (27.3%) were related to tumor surgery. The most usual compensated case had iatrogenic nerve injury affecting the facial or trigeminal nerves. Of the compensated cases, 79 (71.8%) were treated by specialists, 15 (13.6%) by residents, and the rest by other medical professionals. Patient injuries in ORL are seldom severe and are strongly associated with surgery. A typical compensated injury was one that occurred in a central hospital during working hours. N/A.

The aim of the present study was to demonstrate that patients with pathology affecting substantial regions of the cerebellum can improve their performance in a series of two-dimensional tracing tasks, thus supporting the view that this type of motor behavior can be acquired even when the integrity of this structure is compromised. Eight patients with chronic, isolated cerebellar lesions and eight age- and sex-matched healthy controls were tested. Three patients had mild, five had moderate upper limb ataxia. The experiment was divided into two parts. In the first, subjects traced an irregularly shaped outline over 20 consecutive trials ('Trace 1' task). Next, subjects were asked to redraw the object without any underlying template as a guide ('Memory 1' task). In the second part of the study, subjects were asked to trace a different, irregularly shaped outline over 20 consecutive trials ('Trace 2' task). Next, they were required to redraw it by memory with its axis rotated 90 degrees ('Memory 2' task). In each of the memory tasks the template was placed over the drawn image after each trial and shown to the subjects. The error of performance was determined by calculating three different measurements, each focused on different aspects of the task. Based on these measurements, the cerebellar patients showed improvement in both memory tasks. In the 'Memory 1' task the calculated error decreased significantly for the patients with mild ataxia. In the 'Memory 2' task all cerebellar patients improved their performance substantially enough to reduce significantly the magnitude of all three error measurements. The experiments demonstrate that patients with cerebellar lesions are capable of improving substantially their performance of a complex motor task involving the recall of memorized shapes and the visuomotor control of a tracing movement.

Aesthetic surgery is a service which entails a high degree of trust. Service evaluation prior to provision is difficult for the patient. This leads to the question of how to manage the service successfully while still focusing on the medical needs. The decision to undergo an operation is not influenced by the operation itself, but by preoperative events which induce the patient to have the operation done. According to "buying decisions" for products or in service management, the decision for an aesthetic operation is extensive; the patient is highly involved and actively searching for information using different directed sources of information. The real "buying decision" consists of 5 phases: problem recognition, gathering of information, alternative education, purchase decision, and post purchase behaviour. A retrospective survey of 40 female patients who have already undergone an aesthetic operation assessed for problem recognition, which types of information were collected prior to the appointment with the surgeon, and why the patients have had the operation at our hospital. They were also asked how many alternative surgeons they had been seen before. Most of the patients had been thinking about undergoing an operation for several years. They mainly used the web for their research and were informed by other (non-aesthetic) physicians/general practitioners. Requested information was about the aesthetic results and possible problems and complications. Patients came based on web information and because of recommendations from other physicians. 60% of all interviewees did not see another surgeon and decided to have the operation because of positive patient-doctor communication and the surgeon's good reputation. Competence was considered to be the most important quality of the surgeon. However, the attribute was judged on subjective parameters. Environment, office rooms and staff were assessed as important but not very important. Costs of surgery were ranked second

After studying this article, the participant should be able to: 1. Identify the skeletal changes in the cleft patient that necessitate surgery. 2. Describe the orthodontic principles that precede surgical treatment. 3. Demonstrate the surgical principles involved in cleft orthognathic surgery and how to avoid common pitfalls particular to cleft orthognathic surgery. 4. Anticipate when dentoalveolar distraction can help in the treatment of problems not easily treated with conventional orthognathic techniques. This CME article covers the basic multidisciplinary approach to the treatment of patients requiring a combined orthodontic orthognathic approach to their skeletally based malocclusion. The dentoskeletal abnormalities are described for these patients, as are the fundamental orthodontic principles in the presurgical treatment of these patients. The basic surgical principles are discussed in general, and the reader is provided with advice on avoiding common pitfalls. Specific attention is given to the more recent advances in dentoalveolar distraction in cases of large defects that would have been difficult to treat using conventional orthognathic surgery. Videos are provided to illustrate the general principles in treating the cleft orthognathic patient and to illustrate the treatment of large defects using dentoalveolar distraction.
Invasive aspergillosis (IA) is still one of the leading causes of morbidity and mortality in hematological patients, although its outcome has been improving. Prolonged and profound neutropenia in patients receiving intensive chemotherapy for acute leukemia and stem cell transplantation is a major risk factor for IA. Allogeneic stem cell transplant recipients with graft-versus-host disease and corticosteroid use are also at high risk. Management in a protective environment with high efficiency particular air (HEPA) filter is generally recommended to prevent aspergillosis in patients with prolonged and profound neutropenia. Antifungal prophylaxis against Aspergillus species should be considered in patients with past history of aspergillosis or colonization of Aspergillus species, at facilities with high incidence of IA and those without a protective environment. Early diagnosis and prompt antifungal treatment is important to improve outcome. Imaging studies such as computed tomography and biomarkers such as galactomannan antigen and β-D-glucan are useful for early diagnosis. Empirical antifungal treatment based on persistent or recurrent fever during neutropenia despite broad-spectrum antibiotic therapy is generally recommended in high-risk patients. Alternatively, a preemptive treatment strategy has recently been proposed in the context of progress in the early diagnosis of IA based on the results of imaging studies and biomarkers. Voriconazole is recommended for initial therapy for IA. Liposomal amphotericin B is considered as alternative initial therapy. Combination antifungal therapy of echinocandin with voriconazole or liposomal amphotericin B could be a choice for refractory cases.

Full Text Available Cancer, which is one of the major health problems leading to despair, uncertainty, pain and suffering, is perceived as a serious and chronic disease. Cancer negatively affects individuals' quality of life due to the physical, psychological, and socio-economic problems. Today, despite inspiring advances in diagnosis and treatment of cancer and increase in survival rates of patients, appearance of physical and psycho-social disorders during cancer course disrupts the adaptation mechanisms of patients and undermines expectations for the future. Most of the time in clinical practice, clinicians focus on physical assessments and treatment planning of cancer patients primarily, ignoring social, psychological, economic and cultural factors related with the disease. This approach definitely influences patients' hope levels and their effective dealing with the disease. The aim of this article is to guide medical staff and increase awareness about the concept of hope in patients with cancer.

Conditional reasoning (if p then q) is used very frequently in everyday situations. Conditional reasoning is impaired in brain-lesion patients, psychopathy, alcoholism, and polydrug dependence. Many neurocognitive deficits have also been described in schizophrenia. We assessed conditional reasoning in 25 patients with schizophrenia, 25 depressive patients, and 25 controls, using the Wason selection task in three different domains: social contracts, precautionary rules, and descriptive rules. Control measures included depression, anxiety, and severity of schizophrenia measures as a Verbal Intelligence Scale. Patients with schizophrenia were significantly impaired on all conditional reasoning tasks compared to depressives and controls. However, the social contract and precautions tasks yielded better results than the descriptive tasks. Differences between groups disappeared for social contract but remained for precautions and descriptive tasks when verbal intelligence was used as a covariate. These results suggest that domain-specific reasoning mechanisms, proposed by evolutionary psychologists, are relatively resilient in the face of brain network disruptions that impair more general reasoning abilities. Nevertheless, patients with schizophrenia could encounter difficulties understanding precaution rules and social contracts in real-life situations resulting in unwise risk-taking and misunderstandings in the social world.
Full Text Available Introduction: Due to a variety of circumstances and world-wide research findings, patient safety andquality care during hospitalization have emerged as major issues. Patient safety deficits may burdenhealth systems as well as allocated resources. The international community has examined severalproposals covering general and systemic aspects in order to improve patient safety; several long-termprograms and strategies have also been implemented promoting the participation of health-relatedagents, and also government agencies and non-governmental organizations.Aim: Those factors that have negative correlations with patient safety and quality healthcare weredetermined; WHO and EU programs as well as the Greek health policy were also reviewed.Method: Local and international literature was reviewed, including EU and WHO official publications,by using the appropriate keywords.Conclusions: International cooperation on patient safety is necessary in order to improvehospitalization and healthcare quality standards. Such incentives depend heavily on establishing worldwideviable and effective health programs and planning. These improvements also require further stepson safe work procedures, environment safety, hazard management, infection control, safe use ofequipment and medication, and sufficient healthcare staff.

A total of 2,878 unselected subsequent CT examinations carried out in 1984 were analyzed retrospectively. All studies were performed in a university hospital with a centralized department of diagnostic radiology. Most of the patients investigated were hospitalized; there were only 12% outpatients. Of the patients studied 12.6% were older than 65 years and 20.5% older than 60; 17.7% were emergency cases and patients between 16 and 25 years of age represented the largest fraction. In all other age groups the relative distribution between emergency cases and regular studies revealed no significant differences. There was no statistically significant difference between the older age group (patients older than 65 years) and the total population of this study in almost all items investigated, i.e., no differences in CT examination time and no differences in preparation time (time between two CT studies). The rate of abdominal CT examinations was 7% higher in the older age group, while the relative distribution of all other CT examinations was again comparable to the total population under study. Thus, the expected increase in patients in the older age group does not measurably prolong the CT examination time. This statement applies to a major referral center with a high percentage of inpatients. (orig.) [de
The majority of cancer patients becomes malnourished during the course of their disease. Malnutrition deteriorates the efficiency of all kinds of oncologic interventions. As a consequence of it, treatment-related toxicity increases, hospital stay is lengthened, chances of cure and survival as well as the quality of life of the patients worsen. Nutritional status therefore influences all aspects of outcome of oncology care. In spite of this the use of nutritional therapy varies across health care providers but its application is far from being sufficient during active oncology interventions as well as rehabilitation and supportive care. It threatens not only the outcome and quality of life of cancer patients but also the success of oncologic treatments which often demand high input of human and financial resources. Meanwhile application of nutritional therapy is legally regulated in Hungary and a very recent update of the European guideline on cancer patient nutrition published in 2017 is available. Moreover, cost effectiveness of nutritional therapy has been proven in a number of studies. In this review we present the basics of nutritional therapy including nutritional screening and evaluation, nutritional plan, the role of nutrition support teams, oral, enteral and parenteral nutrition, the use of different drugs and special nutrients and the follow-up of the patients.
This paper explores the nature and future of social research on patient-professional interactions. It first sketches the historical background to such research and notes that in the UK and US this was characterised by a focus on the doctor-patient relationship. This research embodied a sceptical view of the power of the medical profession in sustaining and promoting social inequalities, and a critique of 'medical dominance' over other health care professionals and patients. The paper then goes on to outline changes occurring in the nature of professional practice that suggest a fundamental shift in the social relations of health care and the role of medicine. These include a putative loss of public confidence in the medical profession and the authority of science, an increased role of the media in informing patients, and a change in the state's relationship with health care professionals. Finally, the paper outlines some items for a future research agenda, including the need to understand better patient preferences about changes in health care delivery, including a willingness to engage in 'partnership', and the possibilities and barriers to change in professional practice.
Full Text Available By necessity, critically ill patients admitted to intensive care units (ICUs have a high level of dependency, which is linked to a variety of negative feelings, such as powerlessness. However, the term dependency is not well defined in the critically ill patients. The concept of “dependency” in critically ill patients was analyzed using a meta-synthesis approach. An inductive process described by Deborah Finfgeld-Connett was used to analyze the data. Overarching themes emerged that reflected critically ill patients’ experience and meaning of being in dependency were (a antecedents: dependency in critically ill patients was a powerless and vulnerable state, triggered by a life-threatening crisis; (b attributes: the characteristic of losing “self” was featured by dehumanization and disembodiment, which can be alleviated by a “self”-restoring process; and (c outcomes: living with dependency and coping with dependency. The conceptual model explicated here may provide a framework for understanding dependency in critically ill patients.

Patient-centered outcomes research (PCOR) aims to improve care quality and patient outcomes by providing information that patients, clinicians, and family members need regarding treatment alternatives, and emphasizing patient input to inform the research process. PCOR capitalizes on available data sources and generates new evidence to provide timely and relevant information and can be conducted using prospective data collection, disease registries, electronic medical records, aggregated results from prior research, and administrative claims. Given PCOR’s emphasis on the patient perspective, methods to incorporate patient-reported outcomes (PROs) are critical. PROs are defined by the U.S. Food & Drug Administration as “Any report coming directly from patients… about a health condition and its treatment.” However, PROs have not routinely been collected in a way that facilitates their use in PCOR. Electronic medical records, disease registries, and administrative data have only rarely collected, or been linked to, PROs. Recent technological developments facilitate the electronic collection of PROs and linkage of PRO data, offering new opportunities for putting the patient perspective in PCOR. This paper describes the importance of and methods for using PROs for PCOR. We (1) define PROs; (2) identify how PROs can be used in PCOR, and the critical role of electronic data methods for facilitating the use of PRO data in PCOR; (3) outline the challenges and key unanswered questions that need to be addressed for the routine use of PROs in PCOR; and (4) discuss policy and research interventions to accelerate the integration of PROs with clinical data.

A culture of patient safety requires commitment and full participation from all staff members. In 2008, results of a culture of patient safety survey conducted in the perioperative division of the Lehigh Valley Health Network in Pennsylvania revealed a lack of patient-centered focus, teamwork, and positive communication. As a result, perioperative leaders assembled a multidisciplinary team that designed a safety training program focusing on Crew Resource Management, TeamSTEPPS, and communication techniques. The team used video vignettes and an audience response system to engage learners and promote participation. Topics included using preprocedural briefings and postprocedural debriefings, conflict resolution, and assertiveness techniques. Postcourse evaluations showed that the majority of respondents believed they were better able to question the decisions or actions of someone with more authority. The facility has experienced a marked decrease in the number of incidents requiring a root cause analysis since the program was conducted. Copyright © 2012 AORN, Inc. Published by Elsevier Inc.

During the month of Ramadan, all healthy, adult Muslims are required to fast from dawn to sunset. Fasting during Ramadan involves abstaining from food, water, beverages, smoking, oral drugs, and sexual intercourse. Although the Quran exempts chronically ill from fasting, many Muslims with diabetes still fast during Ramadan. Patients with diabetes who fast during the month of Ramadan can have acute complications. The risk of complications in fasting individuals with diabetes increases with longer periods of fasting. All patients with diabetes who wish to fast during Ramadan should be prepared by undergoing a medical assessment and engaging in a structured education program to undertake the fast as safely as possible. Although some guidelines do exist, there is an overwhelming need for better designed clinical trials which could provide us with evidence-based information and guidance in the management of patients with diabetes fasting Ramadan.

Cannabis abuse has been associated with psychiatric disorders. The pattern of cannabis use and incidence of cannabis dependence and cannabis psychosis among 471 consecutive patients admitted to a tertiary care psychiatric center was investigated. Cannabis use was reported by 67 (14.23%) patients of whom 42 (8.92%) were occasional users, 18 (3.82%) were classified as frequent users while 7 (1.49%) fulfilled criteria for cannabis dependence. 3 (0.64%) patients showed symptoms which were characteristic of cannabis psychosis. Among the 67 cannabis users, 56 (83.58%) had their first exposure to cannabis before entering service at 13-19 years of age. The remaining 14 (16.09%) began consuming cannabis 1-5 years after joining service. The reasons given for using cannabis were curiosity about its effects 32 (47.76%), peer pressure 17 (25.37%) or traditional use during festivals 18 (26.87%).

Common regimens of HRT therapy are reviewed, including common routes of hormone administration. Inconsistent patterns of HRT use are discussed, including the reasons women most often give for discontinuing hormone therapies. Specific issues related to misperceptions and fears regarding HRT are clarified, and specific, focused patient education formats are discussed to address women's common concerns about HRT. Obstacles to HRT use are elucidated, with suggestions for clinicians about how to communicate more effectively with women: clinicians must focus on emotional and physical aspects of HRT choices and tailor therapies to the individual patient. Discussing frankly the very serious concerns of women regarding the association between lobular breast cancer and endometrial cancer is important; discussing and preparing women for possible side effects helps patients cope better if and when side effects occur. Finally, offering a wide variety of HRT therapies provides women with a broader choice if an initial regimen is unsuccessful.

We report a successful treatment with lamotrigine of a patient with hereditary coproporphyria presenting with affective and psychotic symptoms. M.F., a 38-year-old, single woman was admitted to an acute psychiatric ward because of suddenly emerging psychosis. Ms F's hereditary coproporphyria was diagnosed 9 years before the current admission. While on treatment with olanzapine (20mg/day) the psychotic symptoms have gradually disappeared. In view of her significant mood fluctuations predominantly with depressed phases, lamotrigine was started and titrated up to 125 mg/day. Ms F's mood gradually became euthymic, suicidal ideations and anxiety disappeared. At 5-month follow-up, while still on lamotrigine, her porphyria was asymptomatic. To the best of our knowledge, this is the first report about the safe administration of lamotrigine in hereditary coproporphyria. Lamotrigine did not trigger an acute porphyric attack as confirmed by clinical and laboratory findings.
Full Text Available Ketogenic diet (KD was usually tried as a last resort in the treatment of intractable epilepsy after failure of many antiepileptics and even epilepsy surgery. Glucose transporter-1 deficiency and pyruvate dehydrogenase deficiency must be treated with KD as the first choice because of inborn errors of glucose metabolism. Infantile spasms, tuberous sclerosis complex, Rett syndrome, Doose syndrome, Dravet syndrome, etc., appear to respond to KD, and it has been suggested by the international consensus statement to use KD early. We believe that all patients with epilepsy, except those with contraindicated situations such as pyruvate carboxylase deficiency, porphyria, β-oxidation defects, primary carnitine deficiency, etc., may try KD before trying other regimens.

To assess the bias, precision and utility of the Bioscanner 2000 for near patient testing of total cholesterol (NPTC) in patients with peripheral arterial disease (PAD). One hundred consecutive patients attending a hospital-based clinic with symptomatic PAD underwent non-fasting NPTC using finger prick blood sample and a laboratory total cholesterol (TC) using blood drawn from an antecubital fossa vein. The Bioscanner 2000 showed good precision with a coefficient of variation of 1.8-3.8%. NPTC was significantly lower than laboratory TC (mean (S.D.) 4.67 (1.1) vs. 5.12 (1.2) mmol/l), p Bioscanner 2000 compared to laboratory testing, which was demonstrated to be a systematic bias using a Bland-Altman plot. Almost half (46%) of the readings differed by > 0.5 mmol/l, 16% by > 1.0 mmol/l and 3% by > 2 mmol/l. This means that if the cut-off for statin treatment were taken as a TC of 5.0 or 3.5 mmol/l then, based on NPTC, alone 18 and 6% of patients, respectively, would not have received a statin. In the present study, NPTC significantly under-estimated TC when compared to laboratory testing. However, in the majority of cases, this would not have affected the decision to prescribe a statin and NPTC testing allows the immediate institution or titration of statin treatment.
