[source] Early and Midterm Results of an Alternative Procedure to Homografts in Primary Repair of Truncus Arteriosus CommunisCONGENITAL HEART DISEASE, Issue 3 2010Pedro Curi-Curi MD ABSTRACT Background., Repair of truncus arteriosus communis (TAC) in the neonatal and early infant period has become a standard practice. We report our experience on primary repair of TAC with a bovine pericardial-valved woven Dacron conduit as an alternative procedure to homografts, with a focus on early and midterm results. Methods., From January 2001 to December 2007, 15 patients with mean age 1.5 years (range 3 months to 8 years), underwent primary repair of simple TAC. Cases with cardiogenic shock, complex-associated cardiac lesions, or adverse anatomy of the truncal valve were excluded. The Collett and Edwards anatomical type classification of TAC was as follows: type I, 13 (87%); and type II, 2 (13%). Right ventricular outflow tract was reconstructed in all the cases with a bovine pericardial-valved woven Dacron conduit. Results., Overall mortality was 6.6% (1 death due to severe pulmonary hypertension). At a mean follow-up of 31 months (range 6,51), there were no deaths (5-year actuarial survival 93.4%). Out of the 14 midterm survivors, three developed stenosis of the pericardial-valved woven Dacron conduit, but only one underwent interventional procedure including percutaneous balloon dilation with stenting for associated left pulmonary artery hypoplasia. The rate of patients with no surgical or percutaneous reinterventions performed because of obstruction of the right ventricular outflow tract reconstruction in the midterm (5 years) was 86%. Conclusions., Truncus arteriosus communis repair with a bovine pericardial-valved woven Dacron conduit can be performed with a very low perioperative mortality and satisfactory midterm morbidity, favorably compared with that reported for the use of homografts. Interventional cardiac catheterization may delay the time of reoperation for inevitable conduit replacement due to stenosis.

[source] Sensitization to 26 fragrances to be labelled according to current European regulationCONTACT DERMATITIS, Issue 1 2007Results of the IVDK, review of the literature To study the frequency of sensitization to 26 fragrances to be labelled according to current European regulation. During 4 periods of 6 months, from 1 January 2003 to 31 December 2004, 26 fragrances were patch tested additionally to the standard series in a total of 21 325 patients; the number of patients tested with each of the fragrances ranged from 1658 to 4238. Hydroxymethylpentylcyclohexene carboxaldehyde (HMPCC) was tested throughout all periods. The following frequencies of sensitization (rates in %, standardized for sex and age) were observed: tree moss (2.4%), HMPCC (2.3), oak moss (2.0), hydroxycitronellal (1.3), isoeugenol (1.1), cinnamic aldehyde (1.0), farnesol (0.9), cinnamic alcohol (0.6), citral (0.6), citronellol (0.5), geraniol (0.4), eugenol (0.4), coumarin (0.4), lilial (0.3), amyl-cinnamic alcohol (0.3), benzyl cinnamate (0.3), benzyl alcohol (0.3), linalool (0.2), methylheptin carbonate (0.2), amyl-cinnamic aldehyde (0.1), hexyl-cinnamic aldehyde (0.1), limonene (0.1), benzyl salicylate (0.1), ,-methylionon (0.1), benzyl benzoate (0.0), anisyl alcohol (0.0). 1) Substances with higher sensitization frequencies were characterized by a considerable number of ,++/+++' reactions. 2) Substances with low sensitization frequencies were characterized by a high number of doubtful/irritant and a low number of stronger (++/+++) reactions. 3) There are obviously fragrances among the 26 which are, with regard to contact allergy, of great, others of minor, and some of no importance at all. [source] Cr(III) reactivity and foot dermatitis in Cr(VI) positive patientsCONTACT DERMATITIS, Issue 3 2006Malene Barré Hansen Chromium allergy has become synonymous with Cr(VI) allergy. However, real exposure to chromium from leather products may include both Cr(III) and Cr(VI). In this study, we investigate the reactivity to both Cr(VI) and Cr(III) in consecutive patients to analyse the relation between foot eczema/leather exposure and reactivity to Cr(III). From March 2002 to December 2004, 2211 consecutive patients with suspected allergic contact dermatitis were patch tested with 0.5% potassium dichromate (Cr(VI)) and 13% chromium trichloride (Cr(III)). A total of 71 (3.2%) patients had a positive reaction to Cr(VI), of which 31 also had a positive Cr(III) reaction. No Cr(VI) negative patients had a positive reaction to Cr(III). An increased risk of foot dermatitis was found in Cr(VI) positive patients with a concomitant positive or doubtful reaction to Cr(III) compared with Cr(VI) positive patients with no reactions to Cr(III). The increased risk was not due to a higher degree of sensitivity to Cr(VI). Leather was reported most frequently as the suspected cause of chromium dermatitis (54%). However, Cr(VI) allergics having foot eczema and positive or doubtful Cr(III) reactions often had positive reactions to other shoe allergens. Thus, Cr(III) allergy is part of a multiple shoe allergy pattern. [source] Corporate social responsibility in Dutch industryCORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 4 2004Jacqueline Cramer This article addresses the experiences gained by 19 Dutch companies with corporate social responsibility (CSR). These companies joined the programme ,From financial to sustainable profit' of the National Initiative for Sustainable Development (NIDO), which ran from May 2000 until December 2002. They focused on two issues: assessing the added value of corporate social responsibility and implementing a structured approach. The Dutch experiment showed that the companies involved were able to specify the added value of CSR by elaborating the economic performance and/or parenting advantage. Unfortunately, a third type of value creation, viz. through protecting the company's reputation, was not elaborated. Moreover, the experiment revealed that among the 19 participating companies experiences were limited in implementing a structured approach towards CSR. By exchanging experiences the companies learned from each other. Such interactive learning turned out to be a helpful support, complementary to the general CSR literature on guidelines, indicators and best practice guides. Although this literature is rapidly growing, knowledge is still lacking in structuring CSR. Copyright © 2004 John Wiley & Sons, Ltd and ERP Environment. [source] Are psychiatrists affecting the legal process by answering legal questions?CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2008Timothy Hardie Background,Psychiatrists are often asked to answer legal questions. The extent to which they answer strictly legal rather than medical matters is not known. Aim,To investigate how strongly psychiatrists in England and Wales express opinions on one legal question , that of diminished responsibility in respect of a murder charge, and how this is related to outcome in court. Method,Our data were extracted from psychiatric reports and case files supplied by the then Department of Constitutional Affairs (now the Ministry of Justice) on cases heard in the Crown Courts between 1 January 1997 and 31 December 2001 in which the defence of diminished responsibility had been raised. The cases had been selected by the Law Commission in their earlier review of partial defences to murder. We devised a reliable system of rating the presence/absence and strength of expression of a legal opinion in the medical reports. We tested the data for relationship between nature and strength of opinion and progression to trial and verdict. Results,Psychiatric reports were available on 143 of 156 cases in which diminished responsibility was considered. They yielded 338 opinions on at least one aspect of diminished responsibility. In 110 (93%) of the 118 cases in which there was a diminished verdict, this was made without trial and, therefore, without reference to a jury. In only eight (27%) out of the 30 cases that went to trial, was a diminished responsibility verdict made. Half of the reports (169) gave a clear opinion on diminished responsibility, a third (121) invited the court to draw a particular conclusion and only 11% (36) provided relevant evidence without answering the legal questions. When there was an opinion or an invitation to make a finding on the legal question, a trial was less likely. A trial was also less likely if reports agreed on what the verdict should be. Conclusions,Psychiatrists frequently answer the legal question of diminished responsibility. The judiciary and medical experts should join in research to examine the consequences of different styles or approaches in presentation of essentially similar evidence in court.

[source] The probabilities of sex offender re-arrestCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2003Roderic Broadhurst Associate Professor Background Estimates of the probabilities of re-arrest for sex offenders apprehended in Western Australia between April 1984 and December 1994 are reported. Population and method Of the 116,151 distinct male persons arrested for the first time from 1984,94, 2785 were identified with at least one sex offence. Subjects on average were followed up for 5.7 years and assessed by criminal record, Aboriginality, bail status, age, occupation and penal intervention. Three criteria, rearrest for any, repeat sex or a violent offence are used to summarize the ,careers' of sex offenders. Results Overall ultimate probabilities of rearrest for any offence were 0.61, for a repeat sex offence 0.33 and for a violent offence 0.51. Probabilities of re-arrest for non-Aboriginal offenders were lower for all definitions. Younger offenders, Aborigines and those with prior arrest for non-sex offences had higher probabilities for any or violent rearrest but older offenders tended to have higher probabilities of repeat sex offending. Community supervision and imprisonment significantly reduced the ,rate' or speed of re-arrest. Discussion Actuarial risk assessments for low-probability high-consequence events such as dangerous recidivism are useful for identifying groups with a high probability of rearrest, assisting management of these groups and evaluating penal interventions.

[source] Changes in patterns of excessive alcohol consumption in 25 years of high security hospital admissions from England and WalesCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 1 2003Celia McMahon Background It is now generally acknowledged that alcohol abuse increases the risk of violence among people with major mental disorder. Studies in the 1980s and earlier, however, tended to report an inverse relationship between their alcohol use and violence. Aims A study was undertaken to test a hypothesis that among people with major mental disorder considered to pose a serious risk to others the likelihood of excessive alcohol consumption in a period leading up to a violent or dangerous act has increased over time. Methods Analysis was made of annual high security hospital admission cohort case register data of 1 January 1975 to 31 December 1999; alcohol use data were taken from interview and records, and problem drinking defined as consumption of alcohol in excess of 21 units per week during the 12 months prior to the index offence or act. Results There was a linear increase in the proportion of patients in five-year admission cohorts who had engaged in excessive alcohol consumption during the year prior to their index offence or act. The increase was steeper among women than men, but cut across all diagnosis and offending groups. It was strongly associated with increasing tendency to abuse illicit drugs. Conclusions The greater proportion of patients affected by excessive alcohol consumption occurred in spite of a reduction over the same period in admission of people in the diagnostic groups most likely to be implicated in substance misuse (personality disorder). This increased trend may simply reflect similar trends in the general population, but may also be associated with a lack of services or current consensus on appropriate treatment for patients whose mental illness is complicated by excessive alcohol use. Regardless, the trend suggests a growing need for ,dual diagnosis' services within and outside high security hospital. Copyright © 2003 Whurr Publishers Ltd. [source] THE SHORT-TERM EFFECTS OF EXECUTIONS ON HOMICIDES: DETERRENCE, DISPLACEMENT, OR BOTH?,CRIMINOLOGY, Issue 4 2009KENNETH C. LAND Does the death penalty save lives? In recent years, a new round of research has been using annual time-series panel data from the 50 U.S. states for 25 or so years from the 1970s to the late 1990s that claims to find many lives saved through reductions in subsequent homicide rates after executions. This research, in turn, has produced a round of critiques, which concludes that these findings are not robust enough to model even small changes in specifications that yield dramatically different results. A principal reason for this sensitivity of the findings is that few state-years exist (about 1 percent of all state-years) in which six or more executions have occurred. To provide a different perspective, we focus on Texas, a state that has used the death penalty with sufficient frequency to make possible relatively stable estimates of the homicide response to executions. In addition, we narrow the observation intervals for recording executions and homicides from the annual calendar year to monthly intervals. Based on time-series analyses and independent-validation tests, our best-fitting model shows that, from January 1994 through December 2005, evidence exists of modest, short-term reductions in homicides in Texas in the first and fourth months that follow an execution,about 2.5 fewer homicides total. Another model suggests, however, that in addition to homicide reductions, some displacement of homicides may be possible from one month to another in the months after an execution, which reduces the total reduction in homicides after an execution to about .5 during a 12-month period. Implications for additional research and the need for future analysis and replication are discussed. [source] The diagnostic value of on-site cytopathological evaluation and cell block preparation in fine-needle aspiration cytology of liver massesCYTOPATHOLOGY, Issue 5 2006K. Ceyhan Objective:, The aims of this study were to evaluate the typing accuracy of conventional smear (CS), cell block (CB) preparations and combined use of both procedures (CS + CB) for the diagnosis of hepatic malignancies and to determine whether immediate on-site cytopathological evaluation improves the diagnostic yield of liver fine-needle aspiration cytology (FNAC). Methods:, Ultrasound-guided FNABs were performed on 323 consecutive cases with liver masses between December 2002 and December 2004. Histologically and/or clinically correlated 167 cases were included in the study. Preliminary FNAB results, results of CS, CB, and combined use of CS and CB were compared regarding diagnostic sensitivity, specificity, and accuracy for the diagnosis of malignancy. Subtyping accuracies of different methods were also compared. Results:, The sensitivity of on-site cytopathological examination and CS were both 92.8%. The sensitivity of CS + CB was slightly better than that of CB (93.5% versus 84.8%). Specificity of all procedures was achieved 100%. Diagnostic accuracy of on-site cytopathological evaluation, CS, CB, and CS + CB were 93.9%, 93.9%, 87.2%, and 94.5%, respectively. A specific subtype diagnosis of malignant tumours could be rendered accurately on the basis of preliminary diagnosis in 71%, CS in 75.4%, CB in 78.3% and combined approach in 92% of cases. In terms of typing accuracy, 87.5% of HCCs, 93.2% of adenocarcinomas, 92.3% of neuroendocrine carcinomas, 100% of lymphomas and 100% of other malignant tumours were correctly subclassified in the final cytopathological diagnosis. The agreement between preliminary diagnosis and final cytopathological diagnosis was 77.2%. Conclusion:, With use of on-site cytopathological evaluation and combined use of CS and CB, the diagnostic accuracy of liver tumours approaches 100% and also significantly improve diagnostic and subtyping accuracy of liver malignancies. [source] Frequency of intrusive luxation in deciduous teeth and its effectsDENTAL TRAUMATOLOGY, Issue 4 2010Vivian Carvalho Second, to investigate the sequelae of total and partial intrusive luxation in the primary anterior teeth and in their successors and finally, to establish whether the sequelae on both deciduous and permanent teeth were related to the child's age at the time of the intrusion. Data collected from records of 169 boys and 138 girls, all between the ages of zero and 10 years, who were undergoing treatment during the period of March 1996 to December 2004. The sample was composed of 753 traumatized deciduous teeth, of which 221 presented intrusive luxation injury. Children with ages ranging from one to 4 years were the most affected with falls being the main cause of intrusion. Of all intruded teeth 128 (57.9%) were totally intruded and 93 (42.1%) partially. Pulp necrosis/premature loss and color change were the most frequent sequelae in both total and partial intrusions. Concerning permanent dentition, the most common disturbances were color change and/or enamel hypoplasia. Both types of intrusion caused eruption disturbance. Total intrusion was the most frequent type of intrusive luxation. There was no significant correlation between the child's age at the time of intrusion and the frequency of subsequent sequela on primary injured teeth (P = 0.035), between the age at the time of injury and the developmental disturbances on permanent teeth (P = 0.140). [source] Enhancing the Growth of Natural Eyelashes: The Mechanism of Bimatoprost-Induced Eyelash GrowthDERMATOLOGIC SURGERY, Issue 9 20102Article first published online: 2 APR 2010, JOEL L. COHEN MD BACKGROUND Many women desire prominent eyelashes. In December 2008, bimatoprost ophthalmic solution 0.03% was approved for the treatment of hypotrichosis of the eyelashes in the United States. OBJECTIVE To review eyelash physiology and the proposed mechanisms by which the topical pros-tamide product bimatoprost enhances eyelash growth. METHODS AND MATERIALS Clinical and preclinical studies pertaining to the efficacy, safety, and mechanisms of action of bimatoprost are presented. RESULTS Treatment with bimatoprost increases the percentage of eyelash follicles in anagen at any one time. This probably accounts for its ability to lengthen lashes. Bimatoprost-induced stimulation of melanogenesis appears to result in darker lashes and, at the same time, appears to increase the size of the dermal papilla and hair bulb, affecting lash thickness and fullness. Such effects, largely demonstrated in animal studies, are consistent with the results of a recent Food and Drug Administration phase III clinical trial. The favorable safety profile of bimatoprost in human subjects is probably secondary to the limited exposure of ocular tissues resulting from topical application at the base of the upper lashes. CONCLUSION By influencing the eyelash hair cycle and follicles, bimatoprost ophthalmic solution 0.03% is a safe and effective means of enhancing eyelash growth.

[source] Prevalence of Methicillin-Resistant Staphylococcus aureus in the Setting of Dermatologic SurgeryDERMATOLOGIC SURGERY, Issue 3 2009ROGER S. SICA DO BACKGROUND The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in the postoperative setting of dermatologic surgery is unknown. Such data could influence the empirical treatment of suspected infections. OBJECTIVE To examine the period prevalence of MRSA infections in the postoperative setting of dermatologic surgery. METHODS We performed chart reviews of 70 patients who had bacterial cultures taken from January 2007 to December 2007. In the 21 postsurgical cases, we analyzed age, risk factors, sites of predilection, method of repair, and pathogen of growth. RESULTS The mean age of the overall study population was 57, with the mean age of postsurgical MRSA-positive cases being 75.5. Of the 21 postsurgical cultures taken, 16 cultures grew pathogen, and two of the 16 (13%) pathogen-positive cultures grew MRSA. LIMITATIONS This is a retrospective chart review of a relatively small sample size in one geographic location. Our patient population is known to contain a large number of retirees. CONCLUSION The increasing prevalence of MRSA skin and soft tissue infections and recommendation to modify empirical antibiotic therapy have been well documented in particular patient populations, but we caution against the empirical use of MRSA-sensitive antibiotics in the postoperative setting of dermatologic surgery. We advocate culturing all infectious lesions upon presentation and reserve empirical use of MRSA-sensitive antibiotics for high-risk patients or locations. [source] Guidelines for Sclerotherapy of Varicose Veins (ICD 10: I83.0, I83.1, I83.2, and I83.9)DERMATOLOGIC SURGERY, Issue 5 2004E. Rabe MD Background. Sclerotherapy is the targeted elimination of intracutaneous, subcutaneous, and/or transfascial varicose veins (perforating veins) as well as the sclerosation of subfascial varicose vessels in the case of venous malformation by the injection of a sclerosant. With duplex-guide sclerotherapy and foam sclerotherapy, modified methods came into use. Objective. The objective was to create a guideline, based on the available publications and on the European Consensus Document on foam sclerotherapy from April 2003. Methods. This guideline was drafted on behalf of the German Society of Phlebology (Deutsche Gesellschaft für Phlebologie) and adopted by the committee and scientific advisory board of the Deutsche Gesellschaft für Phlebologie on June 15, 2001, and amended on December 5, 2003. The guideline considers the present state of knowledge as reflected in the literature. Conclusions. This guideline represents the recent state of the art of sclerotherapy of varicose veins in Germany including foam sclerotherapy. [source] Sclerosing Foam in the Treatment of Varicose Veins and Telangiectases: History and Analysis of Safety and ComplicationsDERMATOLOGIC SURGERY, Issue 1 2002Alessandro Frullini MD objective. To review the use of sclerosing foam in the treatment of varicose veins, to describe the different techniques of foam preparation, and to report the complications of our 3-year experience with this treatment. method. From November 1997 to the end of October 2000, 453 patients were treated with a sclerosing foam for large, medium, and minor varicosities with sodium tetradecylsulfate (STS) or polidocanol (POL). A first group of 257 patients (90 for minor varicosities and 167 for medium to large veins) received a sclerosing foam according to the Monfreux technique. From December 1999 to October 2000, 196 patients were treated with a sclerosing foam prepared according to Tessari's method (36 for minor size veins or teleangectasias and 170 for medium-large veins). Every patient was studied with (color-flow) duplex scanning before and after the treatment and large vein injections were administered under duplex guide. results. The immediate success rate was 88.1% in the first group for the medium-large veins. In the same districts we registered an early success rate in 93.3% for the patients treated with the Tessari's method. The complication rate (mostly minor complications) was 8.5% in the first group and 7.1% in the second group. conclusion. The use of sclerosing foam may become an established therapy in the treatment of varicose veins with a high success rate, low cost, and low major complication rate. According to our actual experience and knowledge, the safe amount of foam should not exceed the 3-ml limit, but further advancements could come from standardization of the foam preparation technique. [source] Treatment-resistant bipolar depression: towards a new definitionACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2009I. Pacchiarotti Objective:, To summarize the conceptual and operational definitions of treatment-resistant bipolar depression and to review the evidence-based therapeutic options. Method:, Structured searches of PubMed, Index Medicus, Excerpta Medica and Psyclit conducted in December 2008. Results:, Criteria for treatment resistance in bipolar depression are commonly based on concepts stemming from treatment resistance as defined for unipolar depression, an approach that proved to be inadequate. In fact, the addition of an ad hoc criterion based on lithium and other mood stabilizer unresponsiveness after reaching adequate plasma levels appears to be a patch that attempts to take into account the uniqueness of bipolar depression but fails to become operational. Recent data from randomized clinical trials of new anticonvulsants and second-generation antipsychotics should lead to the development of a modern definition of treatment-resistant bipolar depression, and specific therapeutic algorithms. Conclusion:, We suggest a redefinition of resistant bipolar I and II depression. We propose different degrees of severity within bipolar depression in a stepwise manner. [source] EXPLORING DISPARITIES BETWEEN GLOBAL HIV/AIDS FUNDING AND RECENT TSUNAMI RELIEF EFFORTS: AN ETHICAL ANALYSISDEVELOPING WORLD BIOETHICS, Issue 1 2007TIMOTHY CHRISTIE ABSTRACT Objective:, To contrast relief efforts for the 26 December 2004 tsunami with current global HIV/AIDS relief efforts and analyse possible reasons for the disparity. Methods:, Literature review and ethical analysis. Results:, Just over 273,000 people died in the tsunami, resulting in relief efforts of more than US$10 bn, which is sufficient to achieve the United Nation's long-term recovery plan for South East Asia. In contrast, 14 times more people died from HIV/AIDS in 2004, with UNAIDS predicting a US$8 bn funding gap for HIV/AIDS in developing nations between now and 2007. This disparity raises two important ethical questions. First, what is it that motivates a more empathic response to the victims of the tsunami than to those affected by HIV/AIDS? Second, is there a morally relevant difference between the two tragedies that justifies the difference in the international response? The principle of justice requires that two cases similarly situated be treated similarly. For the difference in the international response to the tsunami and HIV/AIDS to be justified, the tragedies have to be shown to be dissimilar in some relevant respect. Are the tragedies of the tsunami disaster and the HIV/AIDS pandemic sufficiently different, in relevant respects, to justify the difference in scope of the response by the international community? Conclusion:, We detected no morally relevant distinction between the tsunami and the HIV/AIDS pandemic that justifies the disparity. Therefore, we must conclude that the international response to HIV/AIDS violates the fundamental principles of justice and fairness. [source] What Determines Cross-Country Access to Antiretroviral Treatment?DEVELOPMENT POLICY REVIEW, Issue 3 2006Nicoli Nattrass Despite the recent international effort to expand access to highly active antiretroviral therapy (HAART) in developing countries, its coverage still varies significantly from country to country and is strongly correlated with per capita income. However, regional and political variables are also important. Cross-country regressions indicate that, controlling for political and economic characteristics and the scale of the HIV epidemic, Latin American and African countries have better coverage than predicted. Whereas the level of HIV prevalence was a significantly (negative) factor when accounting for HAART coverage in June 2004, this effect had disappeared by December 2004. The improvement appears to have benefited democratic countries in particular. [source] Social functioning as an outcome measure in schizophrenia studiesACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2007T. Burns Objective:, Deficits in social functioning are a core feature of schizophrenia. Method:, A literature search of English language articles published between January 1990 and December 2006 was undertaken to identify: i) scales used most frequently to assess social functioning in schizophrenia; and ii) the most frequently used social functioning scales in randomized, controlled trials of antipsychotics. A further search (without time limits) examined their psychometric properties. Results:, A total of 301 articles employed social functioning scales in the assessment of schizophrenia. These contained 87 potentially relevant measures. Only 14 randomized, controlled studies of antipsychotic agents were identified that examined social functioning. Scales varied greatly in terms of measurement approach, number and types of domains covered and scoring systems. A striking lack of data on psychometric properties was observed. Conclusion:, Limited consensus on the definition and measurement of social functioning exists. The Personal and Social Performance Scale is proposed as a useful tool in future research. [source] Infantile spasms and cytomegalovirus infection: antiviral and antiepileptic treatmentDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 9 2007Dorota Dunin-Wasowicz MD PhD From 1 January 1995 to 31 December 2004, 22 patients (13 males, nine females; age range 2-12mo) with infantile spasms and cytomegalovirus (CMV) infection were treated with intravenous ganciclovir (GCV) and antiepileptic drugs. GCV was given for 3 to 12 weeks with a 1-month interval (one, two, or three courses). Epileptic spasms occurred before (group A: eight patients), simultaneously (group B: eight patients), and after (group C: six patients) a diagnosis of human CMV (HCMV) infection and antiviral treatment. In 11 patients, DNA HCMV was found in cerebrospinal fluid by nested-polymerase chain reaction method (neuroinfection). All infants excreted CMV in urine. DNA HCMV and specific immunoglobulin M and immunoglobulin G antibodies were present in blood. Ten patients, including four with neuroinfection, have been seizure-free for at least the past 18 months. In two patients with neuroinfection, vigabatrin monotherapy was withdrawn after a 2 year 6 month seizure-free period. Eighteen patients required antiepileptic drugs polytherapy, four of whom required additional adrenocorticotropic hormone (ACTH). Six patients on polytherapy were seizure-free on follow-up, two of whom were treated with ACTH, but no patient with hypsarrhythmia who required ACTH treatment was seizure-free on follow-up. In five patients, psychomotor development was normal, 16 had tetraplegia (Gross Motor Function Classification System [GMFCS] Level V), and one had diplegia (GMFCS Level III). Early antiviral and antiepileptic therapy could result in the long-term cessation of seizures. [source] White matter alterations associated with chromosomal disordersDEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 3 2004Angels García-Cazorla MD White matter alterations in chromosomal disorders have been reported mainly in 18q-syndrome. Our aim was to evaluate white matter alterations in patients with chromosomal abnormalities detected through conventional cytogenetic techniques. Forty-four patients with chromosomal abnormalities, excluding trisomy 21, were diagnosed in our hospital between May 1999 and December 2002 (24 males, 20 females; mean age 6 years 4 months [SD 3 years 2 months], range 0 to 18 years). Of the 44 patients, 14 had brain magnetic resonance imaging (12 males, 2 females; mean age 4 years 2 months [SD 4 years 4 months]; five with sex chromosomal disorders [SCD] and nine with autosomal chromosomal disorders [ACD]). Of these 14 patients, eight (four with SCD and four with ACD) had abnormal white matter findings of similar patterns. These patients had pseudonodular, subcortical, and periventricular white matter high signal intensity images in T2, and fluid-attenuated inversion recovery sequences that were isolated or confluent. The images did not correlate with the neurological clinical state. Given that eight of the 14 patients showed these lesions, their prevalence in different chromosomal abnormalities appears to be high, even though they have not been well reported in the literature. To our knowledge, these alterations have never been described in SCD. We concluded that unknown factors related to the myelination processes may be localized in different chromosomes. [source] A review of studies describing the use of acetyl cholinesterase inhibitors in Parkinson's disease dementiaACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2005I. D. Maidment Objective:, To review the literature relating to the use of acetyl cholinesterase inhibitors in Parkinson's disease dementia (PDD). Method:, MEDLINE (1966 , December 2004), PsychINFO (1972 , December 2004), EMBASE (1980 , December 2004), CINHAL (1982 , December 2004), and the Cochrane Collaboration were searched in December 2004. Results:, Three controlled trials and seven open studies were identified. Efficacy was assessed in three key domains: cognitive, neuropsychiatric and parkinsonian symptoms. Conclusion:, Cholinesterase inhibitors have a moderate effect against cognitive symptoms. There is no clear evidence of a noticeable clinical effect against neuropsychiatric symptoms. Tolerability including exacerbation of motor symptoms , in particular tremor , may limit the utility of cholinesterase inhibitors. [source] The impact of diabetes and obesity on liver histology in patients with hepatitis CDIABETES OBESITY & METABOLISM, Issue 3 2003F. Friedenberg Aim:, An association between diabetes mellitus and HCV has been recognized previously. No study has examined whether there is an independent association between the degree of hepatic fibrosis and the incidence of diabetes in HCV patients when controlling for other risk factors. Methods:, We reviewed the charts of 264 consecutive patients with chronic HCV infection at a referral liver centre from January 1991 to December 1999. Demographic background, medical history, laboratory and liver biopsy results were retrieved. Results:, The prevalence of diabetes was 16.3%. Gender, intravenous drug use, steatosis scores, aminotransferase levels and iron studies were similarly distributed in patients with and without diabetes (all p > 0.05). In contrast, mean age was greater in the diabetic group (49.8 vs. 44.3, p = 0.003). The prevalence of diabetes was substantially higher in African-Americans (p = 0.001) and those with BMI > 30 (p = 0.015). Although the fibrosis score was higher in diabetics (, = 0.14, p = 0.03), that association did not remain significant when controlling for diabetes risk factors (p > 0.3). The degree of steatosis and fibrosis both tended to increase with increasing BMI (, = 0.47, p < 0.001 and , = 0.13, p = 0.03, respectively). Even after controlling for diabetes, age, gender, race, and current alcohol use, those associations remained (both p < 0.001). Conclusions:, The prevalence of diabetes in our group of HCV patients was high, consistent with other studies. Diabetes is not an independent predictor of degree of fibrosis. Body mass index is an independent predictor of both fibrosis and steatosis in HCV patients. [source] Diabetic foot osteomyelitis: a progress report on diagnosis and a systematic review of treatment,DIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue S1 2008A. R. Berendt Abstract The International Working Group on the Diabetic Foot appointed an expert panel to provide evidence-based guidance on the management of osteomyelitis in the diabetic foot. Initially, the panel formulated a consensus scheme for the diagnosis of diabetic foot osteomyelitis (DFO) for research purposes, and undertook a systematic review of the evidence relating to treatment. The consensus diagnostic scheme was based on expert opinion; the systematic review was based on a search for reports of the effectiveness of treatment for DFO published prior to December 2006. The panel reached consensus on a proposed scheme that assesses the probability of DFO, based on clinical findings and the results of imaging and laboratory investigations. The literature review identified 1168 papers, 19 of which fulfilled criteria for detailed data extraction. No significant differences in outcome were associated with any particular treatment strategy. There was no evidence that surgical debridement of the infected bone is routinely necessary. Culture and sensitivity of isolates from bone biopsy may assist in selecting properly targeted antibiotic regimens, but empirical regimens should include agents active against staphylococci, administered either intravenously or orally (with a highly bioavailable agent). There are no data to support the superiority of any particular route of delivery of systemic antibiotics or to inform the optimal duration of antibiotic therapy. No available evidence supports the use of any adjunctive therapies, such as hyperbaric oxygen, granulocyte-colony stimulating factor or larvae. We have proposed a scheme for diagnosing DFO for research purposes. Data to inform treatment choices in DFO are limited, and further research is urgently needed.

Med. 27, 848,851 (2010) Abstract Aims, The aim of the study was to explore the prevalence and clinical characteristics of hand ulcer in hospitalized patients with diabetes. Methods, We analysed 17 subjects with hand ulcer among diabetic inpatients, who were admitted to the Diabetic Foot Care Center, Department of Endocrinology and Metabolism at the West China Hospital of Sichuan University from April 2003 to December 2008. Results, The prevalence of diabetic hand ulcer among hospitalized patients (0.37%) was significantly lower than that of diabetic foot ulcers (9.7%, P = 0.000). The mean age was 62.1 ± 9.4 years. The average known durations of diabetes and glycated haemoglobin (HbA1c) were 5.3 ± 4.9 years and 10.9 ± 2.4%, respectively. All patients lived in the subtropical zone. Fifteen patients (88.2%) were diagnosed with diabetic peripheral neuropathy. Ten patients had hand infection. After therapy, the ulcers healed in 13 patients (76.5%) and none of them experienced amputation. The average hospital stay for patients with local infection was characteristically longer than that for patients without infection (P = 0.012). The prognosis of the hand ulcer was poorer in the patients who had diabetes for > 3 years compared with those who had diabetes for < 3 years (P = 0.009). Conclusions, Diabetic hand ulcer is a relatively rare complication of diabetes in South-West China. Long duration of diabetes, poorly controlled blood glucose, minor trauma and delayed treatment are the risk factors. Diabetic peripheral neuropathy may play an important role in the pathogenesis of hand ulcer. Early control of blood glucose with insulin and early anti-microbial therapy with appropriate antibiotics are crucial. Debridement and drainage are necessary for hand abscesses.
