Should a person with history of drug addiction be categorically denied as a bone marrow donor? The answer to the question is controversial. We report a case of allogeneic bone marrow transplantation for refractory acute myeloid leukemia preceded by essential thrombocythemia. The donor used cocaine and marijuana the night before the bone marrow harvest. Copyright 2001 S. Karger AG, Basel

Induction of NPY/AgRP orexigenic peptide expression in rat hypothalamus is an early event in fasting: relationship with circulating leptin, insulin and glucose.

PubMed

Palou, Mariona; Sánchez, Juana; Rodríguez, Ana M; Priego, Teresa; Picó, Catalina; Palou, Andreu

2009-01-01

Hypothalamus is crucial in the control of energy intake and expenditure in mammals, presenting two interconnected populations of neurons producing orexigenic NPY/AgRP (neuropeptide Y; agouti related peptide) and anorexigenic POMC/CART (pro-opiomelanocortin; cocaine and amphetamine regulated transcript) neuropeptides. We aimed to shed more light on the response and sensitivity in the production of these neuropeptides to face nutritional changes, particularly food deprivation, and on the signals that regulate them. Male Wistar rats were fasted for 0, 4, 8 and 24h and refed for 3h after 8h fasting. mRNA levels of gastric and adipose tissue (retroperitoneal, mesenteric and inguinal) leptin, and of hypothalamic NPY, AgRP, POMC, CART, leptin receptor, SOCS3 (suppressor of cytokine signaling 3) and insulin receptor were analyzed. Gastric and circulating leptin, and circulating insulin, glucose and ghrelin were also determined. The only neuropeptide mRNAs that responded (increasing) to the short-term periods of fasting used were those of NPY (transiently) and AgRP, and these changes were accompanied by an increase in leptin receptor mRNA levels and by a decrease in adipose and gastric leptin expression and in the circulating levels of leptin, insulin and glucose, but without changes in circulating ghrelin. The elevation in AgRP and leptin receptor mRNA levels and the drop in circulating leptin were not reverted with refeeding. It is suggested that the induction of expression of the orexigenic molecules in NPY/AgRP neurons is an early event upon fasting, related with changes in leptin, insulin and glucose levels, but with the role of leptin signaling in particular. 2009 S.

The processes used to revise the 2008 Basel Statements on the future of hospital pharmacy are summarized, and the revised statements are presented. The process for revising the Basel Statements followed an approach similar to that used during their initial development. The Hospital Pharmacy Section (HPS) of the International Pharmaceutical Federation (FIP) revised the 2008 FIP Basel Statements in four phases, including a survey of hospital pharmacists worldwide, an internal review, online forums, and a face-to-face "World Café" workshop in Bangkok, Thailand. The global survey on the initial Basel Statements included input from 334 respondents from 62 countries. The majority of respondents agreed that most of the initial Basel Statements were acceptable as written and did not require revision. In total, 11 statements were judged by more than 10% of respondents as needing revision or deletion. The FIP HPS executive committee used the survey results to develop 69 initial revised draft statements. After an online discussion with the international hospital pharmacy community, including individuals from 28 countries representing all six World Health Organization regions, a final set of draft statements was prepared for the live discussion involving participants from 20 countries. The final 65 revised Basel Statements were voted on and accepted. Systematic revision of the FIP Basel Statements resulted in an updated reflection of aspirational goals for the future of hospital pharmacy practice. While this revision reflects the development of new goals for hospital pharmacy practice, the core principles of the Basel Statements remain an essential foundation for the discipline.

Most gene mutations associated with Alzheimer's disease point to the metabolism of amyloid precursor protein as a potential cause. The beta- and gamma-secretases are two executioners of amyloid precursor protein processing resulting in amyloid-beta. Significant progress has been made in the selective inhibition of both proteases, regardless of structural information for gamma-secretase. Several peptidic and nonpeptidic leads were identified for both targets. Copyright 2006 S. Karger AG, Basel.

Capsule endoscope aspiration is an increasingly reported complication, potentially responsible for respiratory distress and asphyxia. This adverse event is primarily managed by rigid bronchoscopy when spontaneous expulsion does not occur. This complication is all the more detrimental to patients as it can delay or jeopardize further digestive exploration.

Extracellular polysaccharides (EPS) could increase the penetration of fluoride through dental biofilm, reducing its cariogenicity. We measured the concentration of fluoride in EPS-containing (EPS+) or not-containing (EPS-) Streptococcus mutans bacterial pellets resembling test biofilms, before and up to 60 min after a 0.05% NaF rinse in situ. Fluoride penetration and clearance were higher in EPS+ bacterial pellets. The data suggest that EPS enhances fluoride penetration, but also accelerates fluoride clearance from dental biofilms. © 2018 S. Karger AG, Basel.

Impact of Serum Vancomycin Trough Levels in the Treatment of Central Nervous System Shunt Infections Caused by Coagulase-Negative Staphylococci.

PubMed

Gibson, Ashley; Kaplan, Sheldon L; Vallejo, Jesus G

2018-04-26

Coagulase-negative staphylococci (CoNS) are a common cause of pediatric ventricular shunt infections. The Infectious Diseases Society of America recommends vancomycin serum troughs of 15-20 µg/mL when treating CoNS shunt infections in adult patients. We report a series of pediatric cases of CoNS shunt infections in which clinical cure was obtained with troughs < 15 µg/mL. These findings question the relevance of this recommendation in pediatric patients. © 2018 S. Karger AG, Basel.

Endoscopic, single-catheter treatment of Dandy-Walker syndrome hydrocephalus: technical case report and review of treatment options.

PubMed

Sikorski, Christian W; Curry, Daniel J

2005-01-01

Optimal treatment for hydrocephalus related to Dandy-Walker syndrome (DWS) remains elusive. Patients with DWS-related hydrocephalus often require combinations of shunting systems to effectively drain both the supratentorial ventricles and posterior fossa cyst. We describe an endoscopic technique, whereby a frontally placed, single-catheter shunting system effectively drained the supratentorial and infratentorial compartments. This reduces the complexity and potential risk associated with the combined shunting systems required by so many with DWS-related hydrocephalus. Copyright 2005 S. Karger AG, Basel.

Cancer in the adolescent and young adult (AYA) is the second leading cause of nonaccidental death with hematological malignancies spiking during this period. Treatment of AYAs with hematological malignancies usually follows either pediatric or adult protocols with sufficient information lacking on subgroup analyses regarding course and outcome. In this review we will outline up-to-date treatment possibilities for AYAs diagnosed with Hodgkin's lymphoma. Early and late toxicities will be addressed and future directions of research suggested. © 2014 S. Karger AG, Basel.

Little is known about why patients with cancer do or do not donate their biopsied/cancerous tissue to research. A review of the literature on motivations to participate in clinical research and to donate tissues/organs for therapeutic use may provide some insights relevant to tumour banking research. While more research is necessary, a better understanding of the factors that motivate patients to give or refuse consent to tumour banking may ultimately improve consent practices, public trust and donation rates.

Narlawar, Rajeshwar; Baumann, Karlheinz; Schubenel, Robert; Schmidt, Boris

2007-01-01

Curcumin-derived oxazoles and pyrazoles were synthesized in order to minimize the metal chelation properties of curcumin. The reduced rotational freedom and the absence of stereoisomers was anticipated to enhance the inhibition of gamma-secretase. Accordingly, the replacement of the 1,3-dicarbonyl moiety by isosteric heterocycles turned curcumin analogue oxazoles and pyrazoles into potent gamma-secretase inhibitors. Compounds 4a-i were found to be potent inhibitors of gamma-secretase and displayed activity in the low micromolar range. 2007 S. Karger AG, Basel

Itch Management in Childhood.

Fölster-Holst, Regina

2016-01-01

Itch in children is a very common symptom and is mainly related to a skin disease rather than an underlying systemic disorder. The most common dermatoses include atopic dermatitis, contact dermatitis, insect bites, scabies, and pediculosis capitis. There are specific diagnostic patterns which require the evaluation of a careful history and dermatological examination. For dermatological treatment, we have to consider that children, especially infants, show differences in physiology and pathophysiology, and also in pharmacokinetics and pharmacodynamics compared with adults. © 2016 S.

Although microvascular complications of diabetes (retinopathy, neuropathy, and nephropathy) affect different organs, they are strongly correlated to each other. Based on recent data, their onset and progression could be directly monitored, focusing our attention only on the eye. When confirmed and standardized, this approach could allow one to simplify the way in which we follow the progression of different diabetic complications, and thus establish new strategies aimed at preventing, treating and, hopefully, inducing the remission of microvascular complications of diabetes. © 2017 S.

2008-01-01

A 9-year-old female child presented with rapid neurological deterioration. Clinical features and imaging findings were suggestive of high-grade malignancy, and hematological investigations were suggestive of sickle cell trait. Histopathology showed features of low-grade malignancy and extensive intratumoral sickling. We hypothesize that the vicious cycle of hypoxia, sickling, thrombosis, ischemia and infarction resulted in the extensive tumor necrosis in the present case causing the initial symptoms and rapid deterioration in the condition of the patient.

Constitutional trisomy 8 mosaicism (CT8M) is a rare chromosomal abnormality. The phenotype varies from normal features to severe malformations. CT8M increases the risk of developing leukemia and myelodysplastic syndrome. As CT8M is very rare, its diagnosis can easily be overlooked, especially in cases with mild phenotypes. Here, we report the diagnostic process of a 40-year-old female patient with CT8M and discuss the importance of follow-up in monitoring for hematological malignancies. © 2016 S. Karger AG, Basel.

Public engagement as a means of restoring public trust in science--hitting the notes, but missing the music?

Wynne, Brian

2006-01-01

This paper analyses the recent widespread moves to 'restore' public trust in science by developing an avowedly two-way, public dialogue with science initiatives. Noting how previously discredited and supposedly abandoned public deficit explanations of 'mistrust' have actually been continually reinvented, it argues that this is a symptom of a continuing failure of scientific and policy institutions to place their own science-policy institutional culture into the frame of dialogue, as possible contributory cause of the public mistrust problem.

This paper takes an international perspective on the marketing of alcohol to young people by examining case studies of the marketing of alcohol in the UK and Poland. It is suggested that marketing is a powerful mechanism for attracting young consumers. The alcohol industry is an innovative industry able to use a wide variety of marketing tools to achieve success in the market-place. It is important to recognise that the marketing activities of the industry are becoming increasingly transnational and that policy response has to be equally transnational. Copyright 2004 S.

Molecular imaging with contrast-enhanced ultrasound uses targeted microbubbles that are retained in diseased tissue. The resonant properties of these microbubbles produce acoustic signals in an ultrasound field. The microbubbles are targeted to diseased tissue by using certain chemical constituents in the microbubble shell or by attaching disease-specific ligands such as antibodies to the microbubble. In this review, we discuss the applications of this technique to pathological states in the cerebrovascular system including atherosclerosis, tumor angiogenesis, ischemia, intravascular thrombus, and inflammation.

Polycystic ovary syndrome (PCOS) is a common and complex endocrinopathy with reproductive, metabolic, and psychological features and significantly increased cardiometabolic risks. PCOS is underpinned by inherent insulin resistance and hyperandrogenism. Obesity, more common in PCOS, plays an important role in the pathophysiology, exacerbating hyperinsulinaemia and hyperandrogenism, leading to recommended first-line lifestyle intervention. Significant traditional and non-traditional risk factors are implicated in PCOS in addition to obesity-exacerbated cardiometabolic risks and are explored in this review to promote the understanding of this common metabolic and reproductive condition. © 2016 S.

Considering the patient's transition from child to adolescent to adult and its psychological aspects in endocrinology and diabetology, it is necessary to recall the child's psycho-affective development when he enters adolescence. Indeed, adolescence appears paradigmatic of the "child-adult" transition; it is a specific and decisive psychic process which allows the child to become an adult, that is to say autonomous and subject to his desire.

To determine the intraocular levels of methotrexate in low-dose treatment of noninfectious uveitis. One day after oral administration, the methotrexate level was measured in the aqueous humor and serum of a patient with noninfectious uveitis, who underwent cataract surgery. A fluorescence polarization immunoassay was used for determination. After oral administration, methotrexate was only measurable in aqueous humor but not in serum. In uveitis, orally administered low-dose methotrexate reaches detectable levels in aqueous humor, even in the absence of detectable levels in serum. Copyright (c) 2005 S. Karger AG, Basel.

Molecular cytogenetic methods defined the size of the inversion as 11.7 Mb and excluded other unbalanced chromosomal alterations in the patients. Our findings suggest that intellectual disability is caused by dysfunction, disruption, or position effects of genes located at or near the breakpoints involved in this inversion. © 2015 S.

Hypertrophic Pachymeningitis and the Syndrome of Inappropriate Antidiuretic Hormone Secretion: Coincidence or Cause?

PubMed

Harsch, Igor Alexander; Schiffer, Anne; Konturek, Peter C

2017-01-01

To investigate a potential cause of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). A 70-year-old female patient had nausea and collapsed. Although euvolemic, pathological laboratory findings showed hyponatremia and hypoosmolality, and cerebral magnetic resonance imaging showed hypertrophic pachymeningitis. Secondary hypertrophic pachymeningitis was excluded. Other nonneurological reasons for SIADH were also excluded. Moderate fluid restriction restored an almost normal serum osmolality and sodium. This case of SIADH was conservatively treated with moderate fluid restriction that almost restored normal serum osmolality and sodium levels. © 2017 S. Karger AG, Basel.

Mucoepidermoid lung tumor appearing as an abscess on the scrotum.

2009-01-01

The authors present the case of a 52-year-old man who had recurring scrotal abscesses resulting in oncotomy being carried out seven times within 2 years. Eventually, it was dissected out totally. Histology proved anaplastic cancer metastasis. The primary tumor was detected in the bronchia; moreover, metastases were found in other organs as well. The patient died 6 weeks after the first diagnosis. We intended to draw attention to frequently occurring scrotal inflammation and thus the underlying diseases. We emphasize the importance of histology examinations. (c) 2009 S. Karger AG, Basel.

Retrobulbar optic neuritis and rhegmatogenous retinal detachment in a fourteen-year-old girl with retinitis pigmentosa sine pigmento.

2000-01-01

A 14-year-old girl complained of a sudden decrease in right visual acuity. The patient had night blindness, a mottled retina but no pigments, extinguished scotopic electroretinographic response, central scotoma in the right eye and rhegmatogenous retinal detachment. She had initially received laser photocoagulation around the retinal tear and then corticosteroid therapy, cryoretinopexy and segmental buckling. Her right visual acuity increased to 1.0. The association of retinitis pigmentosa sine pigmento, retrobulbar optic neuritis and rhegmatogenous retinal detachment, as demonstrated in our patient, may be uncommon. Copyright 2000 S.

Scytalidium dimidiatum melanonychia and scaly plantar skin in four patients from the Maghreb: imported disease or outbreak in a Belgian mosque?

PubMed

Arrese, J E; Piérard-Franchimont, C; Piérard, G E

2001-01-01

Scytalidium dimidiatum is a geophilic dematiaceous, non-dermatophyte mould that can become a pathogen for plants and humans particularly in tropical and subtropical regions. We report 4 cases of S. dimidiatum onychomycosis presenting clinically as thickened and dark toenails. The skin of the soles was scaly. The time and location of the contaminations were uncertain. Indeed, the patients were ancient immigrants from the Maghreb to Belgium. They were also regularly travelling to their countries of origin. They were also often barefoot in the same Belgian mosque. The disease was unresponsive to current oral antifungal treatments. Copyright 2001 S. Karger AG, Basel.

Behavioral studies of learning in the Africanized honey bee (Apis mellifera L.).

Abramson, Charles I; Aquino, Italo S

2002-01-01

Experiments on basic classical conditioning phenomena in adult and young Africanized honey bees (Apis mellifera L.) are described. Phenomena include conditioning to various stimuli, extinction (both unpaired and CS only), conditioned inhibition, color and odor discrimination. In addition to work on basic phenomena, experiments on practical applications of conditioning methodology are illustrated with studies demonstrating the effects of insecticides on learning and the reaction of bees to consumer products. Electron microscope photos are presented of Africanized workers, drones, and queen bees. Possible sub-species differences between Africanized and European bees are discussed. Copyright 2002 S.

Elevated myocardial enzymes and natriuretic peptides in anorexia nervosa: prototypic condition for the pathophysiology of cachexia?

PubMed

Zastrow, Arne; Wolf, Johanna; Giannitsis, Evangelos; Katus, Hugo; Herzog, Wolfgang; Friederich, Hans-Christoph; Mussler, Christina

2011-01-01

We report on a patient suffering from chronic anorexia nervosa who in the course of treatment showed elevated high-sensitive troponin T, creatine kinase and most markedly N-terminal pro-brain natriuretic peptide (NT-proBNP). Elevated enzymes improved significantly throughout the course of treatment without cardiac specific medication but exceeded the normal range for weeks. Abnormally high myocardial enzymes and NT-proBNP in cachectic anorectic patients might resemble conditions of cardiac cachexia. A review of the available literature is provided. Further research is required to explain the pathophysiological meaning of the abnormal laboratory findings. Copyright © 2011 S. Karger AG, Basel.

The endothelin pathway: a protective or detrimental target of bardoxolone methyl on cardiac function in patients with advanced chronic kidney disease?

PubMed

Camer, Danielle; Huang, Xu-Feng

2014-01-01

Bardoxolone methyl has been reported to cause detrimental cardiovascular events in the terminated BEACON Phase III human clinical trial via modulation of the renal endothelin pathway. However, the effects of bardoxolone methyl administration on the endothelin pathway in the heart are unknown. Our purpose in this perspective is to highlight the distinctive opposing roles of the renal and heart endothelin pathway in cardiac function. Furthermore, we address the need for further investigation in order to determine if bardoxolone methyl has a protective role in cardiac function through the suppression of the endothelin pathway in the heart. © 2014 S.

A panel illustrating spinal cord injury in The Dying Lioness in the British Museum dates to 650 BC. This paper outlines the subsequent progression of knowledge of the anatomy of the spinal cord. The animal dissections of Galen are considered because his deductions persisted through the Dark Ages until the late 18th century. Anatomy advanced gradually to yield discoveries of the complex tracts and grey matter elements of the cord and their functions. Amongst many distinguished exponents, the works of Blasius, Huber, Vicq d'Azyr and Stilling are emphasised. (c) 2008 S. Karger AG, Basel

Failure of a vagus nerve stimulator following a nearby lightning strike.

2011-01-01

We recently reported our experience with implanted vagus nerve stimulators (VNS) in 62 children over a 7-year period. Here, we present a case of a VNS that successfully reduced the number and severity of seizures in a patient with an unusual seizure pattern, and failed to function shortly after a lightning storm. To our knowledge, the failure of VNS or any implantable electrical devices by lightning has not been reported in the literature. This mechanism of electrical interference, while unusual, may require more attention as these devices are expected to be used more frequently. Copyright © 2011 S. Karger AG, Basel.

Antimicrobial activity of fluoride and its in vivo importance: identification of research questions.

Van Loveren, C

2001-01-01

This manuscript discusses the antimicrobial activity of fluoride and its in vivo importance in order to identify research questions. There is a lot of information on mechanisms by which fluoride may interfere with bacterial metabolism and dental plaque acidogenicity. The antimicrobial activity of fluoride products is enhanced when fluoride is associated with antimicrobial cations like Sn(2+) and amine. It is not clear whether the antimicrobial mechanisms of fluoride are operating in vivo or even to what extent antimicrobial activity can contribute to caries prevention. This latter question may be the most important one in research. Copyright 2001 S. Karger AG, Basel.

2011-01-01

Metastatic renal cell carcinoma (mRCC) is a difficult to treat malignancy and currently Sunitinib is a standard of care first-line therapy. A new metastasis during the treatment is considered a sign of drug failure and alternative therapeutic methods should be tried. Here, we report 2 cases of newly diagnosed isolated metastasis during Sunitinib treatment of mRCC patients. Our management plan included local palliative therapy to the lesion followed by recommencing of Sunitinib. This resulted in a good symptomatic relief locally as well as good overall control of the disease. Copyright © 2010 S. Karger AG, Basel.

At an intermediate or advanced stage, i.e. stage B or C, based on the Barcelona Clinic Liver Cancer classification of hepatocellular carcinoma (HCC), transarterial chemoembolization (TACE) may be offered as a treatment of palliative intent. We report the case of a patient suffering from acute respiratory distress syndrome after TACE with drug-eluting beads loaded with doxorubicin for HCC. To our knowledge, this is the first case described where a bronchoalveolar lavage was performed, and where significant levels of alveolar eosinophilia and neutrophilia were evident, attributed to a pulmonary toxicity of doxorubicin following liver chemoembolization. © 2014 S.

2018-05-23

The diagnosis and classification of myelodysplastic syndromes (MDS) are based on cytomorphology and cytogenetics (WHO classification). Prognosis is best defined by the Revised International Prognostic Scoring System (IPSS-R). In recent years, an increasing number of molecular aberrations have been discovered. They are already included in the classification (e.g., SF3B1) and, more importantly, have emerged as valuable markers for better classification, particularly for defining risk groups. Mutations in genes such as SF3B1 and IDH1/2 have already had an impact on targeted treatment approaches in MDS. © 2018 S. Karger AG, Basel.

We report a case of a fetus diagnosed at 28 weeks' gestation with a spontaneous prenatal hemothorax. Fetal intervention consisted of 2 thoracenteses with analysis of the pleural effusion. The pregnancy was further complicated by recurrence of the hemothorax, with subsequent mediastinal shift, hydrops, and nonreassuring antenatal testing requiring delivery at 31 weeks' gestation. Postnatal workup established the diagnoses of cutis marmorata telangiectatica congenita (CMTC) and pulmonary lymphangiectasia. The child is currently 4 years old and without any active medical issues or sequelae from the CMTC, pulmonary lymphangiectasia, or prenatal interventions. © 2018 S. Karger AG, Basel.

Geriatrics and law may not be natural bedfellows. Moreover, law and lawyers were not part of the professions that were the 'founding fathers' of the field of geriatrics. In this short viewpoint we invite the readers to consider a new inter-disciplinary research approach that attempts to combine jurisprudence with geriatrics. Geriatric jurisprudence is a special and timely opportunity for doctors and lawyers to come together in a new, different and more united way to jointly conceptualize a medico-legal theory of aging to better serve our shared community: older and aging persons.

The metaphysical art of Giorgio de Chirico. Migraine or epilepsy?

PubMed

Blanke, Olaf; Landis, Theodor

2003-01-01

It has been suggested that the great Italian painter Giorgio de Chirico (1888-1978), who developed the unique style of 'metaphysical art', suffered from migraine and used some of his morbid manifestations as a source of inspiration for his paintings. Yet, whereas many of the symptoms that de Chirico described are rare in migraine, they are frequently encountered in patients with temporal lobe epilepsy. Here we rediscuss de Chirico's symptoms critically and suggest that, if his symptoms were of neurological origin, they rather relate to temporal lobe epilepsy than migraine. Copyright 2003 S.

A gluten-free diet (GFD) is recommended for all patients with coeliac disease (CD). The spectrum of gluten-related disorders in the early 1980s was simple: CD and dermatitis herpetiformis. In the last few years, wheat allergy, gluten ataxia and noncoeliac gluten sensitivity have become new gluten-related topics. Adherence to GFDs in CD is limited and factors influencing adherence are poorly understood. Noncoeliac gluten sensitivity has stimulated the GFD food industry not only in Australia but all over the world. This article provides an overview of GFD in daily practice. Copyright © 2013 S.

This mini review outlines studies of cell volume regulation in two closely related mammalian cell lines: nonadherent Ehrlich ascites tumour cells (EATC) and adherent Ehrlich Lettre ascites (ELA) cells. Focus is on the regulatory volume decrease (RVD) that occurs after cell swelling, the volume regulatory ion channels involved, and the mechanisms (cellular signalling pathways) that regulate these channels. Finally, I shall also briefly review current investigations in these two cell lines that focuses on how changes in cell volume can regulate cell functions such as cell migration, proliferation, and programmed cell death.

2018-01-01

As a disease of kings, and the king of diseases, gout is one of the oldest joint diseases known to humans. First described as far back as 2640 B.C., gout is still the most common form of inflammatory arthritis haunting humans in the 21st century. The disease is caused by the chronic elevation of serum uric acid levels above the saturation point for monosodium urate crystal formation. Its incidence is progressively rising even today, but there are also regional and ethnic variations. Finally, the role of genetics is only beginning to be unraveled. © 2018 S. Karger AG, Basel.

Leonardo Da Vinci and stroke - vegetarian diet as a possible cause.

Leonardo da Vinci (April 15, 1452 to May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. It has been gleaned from the many available historical documents that da Vinci was a vegetarian who respected and loved animals, and that he suffered from right hemiparesis in the last 5 years of his life. A vegetarian diet has both positive and negative influences on the cerebrovascular system. In this report, a possible relation between a vegetarian diet and stroke is discussed from various perspectives as related to Leonardo da Vinci's stroke. Copyright (c) 2010 S. Karger AG, Basel.

Systematic biases in decision-making have been well characterized in medical and nonmedical fields but mostly ignored in clinical psychopharmacology. The purpose of this paper is to sensitize clinicians who prescribe psychiatric drugs to the issues of the psychology of risk, especially as they pertain to the risk of side effects. Specifically, the present analysis focuses on heuristic organization and framing effects that create cognitive biases in medical practice. Our purpose is to increase the awareness of how pharmaceutical companies may influence physicians by framing the risk of medication side effects to favor their products. (c) 2008 S.

The urachal carcinoma, in a 64-year-old male with multiple lung metastases, had shown the resistance to several anti-neoplastic agents including cisplatinum, methotrexate, 5-FU, doxorubicin, epirubicin, and mitomycin C. Because the tumor was adenocarcinoma producing mucin and serum carcinoembryonic antigen (CEA) increased, which resembled colorectal carcinoma, we administrated Irinotecan, which was very effective as the CEA decreased from 98.3 to 38.7 ng/ml and the pulmonary metastatic lesions were reduced by 60%. To our knowledge, this is the first case with urachal carcinoma in which Irinotecan was effective. Copyright (c) 2006 S. Karger AG, Basel.

Clinical observations with AN-1792 using tissue amyloid plaque immunoreactivity (TAPIR) analyses established for the first time evidence in humans that antibodies against beta-amyloid-related epitopes are capable of slowing progression in Alzheimer's disease. Antibodies derived upon TAPIR assay selection may specifically target the pathologic neoepitopes of aggregated A beta species present in amyloid plaques and some of their aggregated, protofibrillar and low molecular weight oligomeric precursors. We briefly summarize here how the proof of concept was established and why it provides the basis for a potential cure for Alzheimer's disease. Copyright 2005 S. Karger AG, Basel.

The history of tattooing goes back for thousands of years, and the reasons for getting tattooed are many. These permanent markings are always personal, they can be plain or elaborate, and they serve as amulets, healing and status symbols, declarations of love, signs of religion, adornments and even forms of punishment. Drivers behind the fascination of acquiring a tattoo may fall into four main groups, namely healing, affiliation, art and fashion. © 2015 S. Karger AG, Basel.

Febrile proteinuria is functional proteinuria and is seen as a transitory phenomenon during acute febrile illness, mainly viral infections. It is a benign phenomenon and clears promptly with resolution of the infection. In this report, we present a patient who was thought to have febrile proteinuria. Persistence of significant proteinuria after resolution of the infection prompted biochemical and genetic work-up which lead to the diagnosis of Dent-2 disease. We recommend the use of sodium dodecyl sulphate electropheresis (SDS-PAGE) for the detection of low molecular weight proteinuria. ©2018The Author(s). Published by S. Karger AG, Basel.

Nannan, Gao; Runmei, Yang; Fusheng, Lin; Shoulan, Zhang; Guangqing, Lei

2007-01-01

The effects of AIT-082, a hypoxanthine derivative, on tremor in mice were investigated. The mice received intragastric administration of AIT-082 for consecutive 60 days at doses of 150, 300 and 600 mg.kg(-1). The results showed that AIT-082 not only effectively inhibited the tremor induced by arecoline or oxotremorine, but also alleviated the tremor intensity and significantly shortened the tremor durations. The inhibition of tremor was perhaps associated with the central cholinergic nerve depressant effects as well as the stimulation of proliferation and differentiation of nerve cells.

Studies of the relationship between behavioral plasticity and new cells in the adult brain in amphibians and reptiles are sparse but demonstrate that environmental and hormonal variables do have an effect on the amount of cell proliferation and/or migration. The variables that are reviewed here are: enriched environment, social stimulation, spatial area use, season, photoperiod and temperature, and testosterone. Fewer data are available for amphibians than for reptiles, but for both groups many issues are still to be resolved. It is to be hoped that the questions raised here will generate more answers in future studies. © 2016 S. Karger AG, Basel.

How to help teachers' voices.

PubMed

Saatweber, Margarete

2008-01-01

It has been shown that teachers are at high risk of developing occupational dysphonia, and it has been widely accepted that the vocal characteristics of a speaker play an important role in determining the reactions of listeners. The functions of breathing, breathing movement, breathing tonus, voice vibrations and articulation tonus are transmitted to the listener. So we may conclude that listening to the teacher's voice at school influences children's behavior and the perception of spoken language. This paper presents the concept of Schlaffhorst-Andersen including exercises to help teachers improve their voice, breathing, movement and their posture. Copyright 2008 S. Karger AG, Basel.

To establish a novel retinal angiography method, red-free angiography (RFA), to investigate retinal changes in age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV). Following the venous phase of fundus fluorescein angiography (FFA), the detection mode was switched to red-free reflectance to acquire RFA images using the same parameters. RFA showed subretinal fluid, polyps, and outer retinal tubulation, with a higher definition than the FFA and red-free reflectance results. The absorption coefficients in RFA provided more detailed images for AMD and PCV diagnosis. RFA is therefore a promising approach to supplement FFA. © 2018 S. Karger AG, Basel.

Fetuses with prenatal Zika virus infection showed retardation in brain maturation indexes evaluated by fetal MR. Brain calcifications were demonstrated by neurosonography in all cases, while fetal MR characterized the specific type of cortical development malformation. © 2017 S. Karger AG, Basel.

Deterministic earthquake scenario for the Basel area: Simulating strong motions and site effects for Basel, Switzerland

NASA Astrophysics Data System (ADS)

OpršAl, Ivo; FäH, Donat; Mai, P. Martin; Giardini, Domenico

2005-04-01

The Basel earthquake of 18 October 1356 is considered one of the most serious earthquakes in Europe in recent centuries (I0 = IX, M ≈ 6.5-6.9). In this paper we present ground motion simulations for earthquake scenarios for the city of Basel and its vicinity. The numerical modeling combines the finite extent pseudodynamic and kinematic source models with complex local structure in a two-step hybrid three-dimensional (3-D) finite difference (FD) method. The synthetic seismograms are accurate in the frequency band 0-2.2 Hz. The 3-D FD is a linear explicit displacement formulation using an irregular rectangular grid including topography. The finite extent rupture model is adjacent to the free surface because the fault has been recognized through trenching on the Reinach fault. We test two source models reminiscent of past earthquakes (the 1999 Athens and the 1989 Loma Prieta earthquake) to represent Mw ≈ 5.9 and Mw ≈ 6.5 events that occur approximately to the south of Basel. To compare the effect of the same wave field arriving at the site from other directions, we considered the same sources placed east and west of the city. The local structural model is determined from the area's recently established P and S wave velocity structure and includes topography. The selected earthquake scenarios show strong ground motion amplification with respect to a bedrock site, which is in contrast to previous 2-D simulations for the same area. In particular, we found that the edge effects from the 3-D structural model depend strongly on the position of the earthquake source within the modeling domain.

Epithelial-mesenchymal transition (EMT) is recognized to play an important role in diabetic nephropathy (DN). To analyze the roles of glycogen synthase kinase 3β (GSK-3β), β-catenin and Snail signaling in high glucose (HG)-induced mouse podocytes EMT. Differentiated podocytes were divided into: the normal glucose group (NG: glucose 5.6mM), the HG groups (12.5HG: 12.5mM; 25HG: 25mM; and 50HG: 50mM of glucose), and the osmotic control group (NG+M: glucose 5.6mM and mannitol 44.4mM). GSK-3β, β-catenin and Snail were assessed using semi-quantitative RT-PCR, western blot and immunofluorescence. β-catenin and Snail pathways were assessed after down-regulating GSK-3β expression using an inhibitor (LiCl) or a small-interfering RNA (siRNA). HG increased GSK-3β, β-catenin and Snail expressions, and promoted EMT, as shown by decreased nephrin expression (epithelial marker), and increased α-SMA expression (mesenchymal marker). GSK-3β inhibitor and GSK-3β siRNA decreased β-catenin and Snail expressions, and reversed HG-induced EMT. Immunofluorescence showed that GSK-3β and β-catenin did not completely overlap; β-catenin was transferred to the nucleus in the 25HG group. VDR seems to be involved in HG-induced β-catenin nuclear translocation. Down-regulating GSK-3β expression decreased β-catenin and Snail expression and reversed HG-induced podocytes EMT. Thus, modulating GSK-3β might be a target to slow or prevent DN. © 2014 S. Karger AG, Basel. © 2014 S. Karger AG, Basel.

A retrospective review of the 41 pregnant women with epilepsy who delivered in the Department of Obstetrics and Perinatology of the University School of Medicine in Lublin over 7 years (1993-1999) was carried out. Women with epilepsy had more pregnancy complications including premature labor, anemia, hypertension, vaginal bleeding, urinary tract infection, nausea and vomiting. An increased risk of congenital malformations and intrauterine fetal growth retardation was observed. Women with epilepsy require more extensive pregnancy planning including neurologic and preconceptional care. Copyright 2001 S. Karger AG, Basel.

Rice: another potential cause of food allergy in patients sensitized to lipid transfer protein.

PubMed

Asero, Riccardo; Amato, Stefano; Alfieri, Beatrice; Folloni, Silvia; Mistrello, Gianni

2007-01-01

Recent studies show that the lipid transfer protein (LTP), the major Rosaceae allergen in patients not sensitized to birch pollen, is a largely cross-reacting allergen. Moreover, it is a potentially hazardous allergen due to its stability upon thermal treatment and pepsin digestion. The present study reports 3 cases of rice-induced anaphylaxis in LTP-allergic patients. In vitro inhibition studies, carried out using LTP purified from both rice and apple as well as whole peach extract, show that LTP was the relevant allergen in these patients and demonstrate the cross-reactivity between rice LTP and peach/apple LTP.

Acamprosate, disulfiram (DIS), naltrexone and nalmefene can be used in treating alcohol use disorders. The drugs are, however, underutilized. In this survey of marketing status and perceived efficacy, member societies of the European federation for addiction societies were asked to report on the status of these drugs in their country. Results were obtained from 20 European countries showing that the drugs were registered in most countries. The drugs were mentioned in guidelines in approximately half and were partially or fully reimbursed in half to two-thirds countries. DIS was perceived as the most efficacious drug. These results are discussed. © 2016 S. Karger AG, Basel.

Searching through studies of schizophrenic delusions with a view to the new media, we came across the case of a young woman who integrated the Internet in her delusional system. Analysing the story she told, we recognised a psychotic symptom, which we preliminarily called 'perception broadcast'. Perception broadcast shows a more complex structure than the related first rank symptom 'thought broadcast' described by Kurt Schneider. In our view the existence of a structure like perception broadcast depends on the existence of new technologies, such as the World Wide Web and 'virtual reality', creating new cultural patterns which themselves are associated with collective perceptions of derealisation.

Use of bioimpedance vector analysis in critically ill and cardiorenal patients.

PubMed

Peacock, W Frank

2010-01-01

Prospective outcome prediction and volume status assessment are difficult tasks in the acute care environment. Rapidly available, non-invasive, bioimpedance vector analysis (BIVA) may offer objective measures to improve clinical decision-making and predict outcomes. Performed by the placement of bipolar electrodes at the wrist and ankle, data is graphically displayed such that short-term morality risk and volume status can be accurately quantified. BIVA is able to provide indices of general cellular health, which has significant prognostic implications, as well as total body volume. Knowledge of these parameters can provide insight as to the short-term prognosis, as well as the presenting volume status. 2010 S. Karger AG, Basel.

It was the aim of this study to measure spectral transmission of the human crystalline lens in situ. The crystalline lens was illuminated by one of four light-emitting diodes of different colors. The relative spectral transmittance of the human crystalline lens was measured with the Purkinje-Sanson mirror images over a wide range of ages. The study evaluated 36 crystalline lenses of 28 subjects aged 21-76 years. There was a significant correlation between the age and spectral transmittance for blue light. Spectral transmittance of the crystalline lens in situ could be measured with Purkinje-Sanson mirror images. Copyright © 2012 S. Karger AG, Basel.

Sustained Erythroid Response in a Patient with Myelofibrosis Receiving Concomitant Treatment with Ruxolitinib and Deferasirox.

Iron overload (IOL) due to transfusion-dependent anemia is a serious adverse effect in patients with myelofibrosis (MF). Recent studies have shown that the oral iron chelator deferasirox may prevent multiple organ damage due to IOL in MF. However, it is not clear whether deferasirox may contribute to revert transfusion-dependent anemia. Here, we present a patient with transfusion-dependent intermediate-2 MF according to the International Prognostic Scoring System treated with ruxolitinib in combination with deferasirox. In addition to a reduced serum ferritin level, the patient required less blood transfusions, ultimately resulting in long-lasting transfusion-free survival. © 2018 S. Karger AG, Basel.

2001-01-01

Monogerminal twin brothers aged 17 were admitted because of concurrent left-sided spontaneous pneumothorax. A familial background of this common disease in association with the human leukocyte antigen (HLA) has been suggested; however, the actual mode of inheritance in association with HLA typing is still uncertain. HLA analysis in this family revealed the HLA-A24, B61 (40), Cw3, DR4, DR53, and DQ3 haplotype in the twins and their father, who also had a medical history of spontaneous pneumothorax. We report these cases as an extremely rare example of familial occurrence of spontaneous pneumothorax. Copyright 2001 S. Karger AG, Basel

Genetic diversity of neotropical primates: phylogeny, population genetics, and animal models for infectious diseases.

PubMed

Moreira, M A M; Bonvicino, C R; Soares, M A; Seuánez, H N

2010-01-01

The classification of neotropical primates has been controversial, and different arrangements have been proposed based on disparate taxonomic criteria and on the traits selected for elucidating phylogenetic reconstructions, like morphologic characters, nuclear DNA and mitochondrial DNA. Population studies of some neotropical primates have been useful for assessing their extant genetic variability and for understanding their social structure and dynamics. Finally, neotropical primates have become valuable models for some human infectious deseases, especially for HIV studies related to viral resistance. In this review, we comment on these aspects that make neotropical primates a group of highly valuable species for basic and applied research. Copyright 2010 S. Karger AG, Basel.

Current indications for pars plana vitrectomy in patients with proliferative diabetic retinopathy (PDR) include vitreous hemorrhage, tractional retinal detachment (TRD), combined tractional and rhegmatogenous retinal detachment (CTRRD), diabetic macular edema associated with posterior hyaloidal traction, and anterior segment neovascularization with media opacities. This chapter will review the indications, surgical objectives, adjunctive pharmacotherapy, microincision surgical techniques, and outcomes of diabetic vitrectomy for PDR, TRD, and CTRRD. With the availability of new microincision vitrectomy technology, wide-angle microscope viewing systems, and pharmacologic agents, vitrectomy can improve visual acuity and achieve long-term anatomic stability in eyes with severe complications from PDR. © 2014 S.

2018-05-23

Iodine is necessary for fetal thyroid development. Excess maternal intake of iodine can cause fetal hypothyroidism due to the inability to escape from the Wolff-Chaikoff effect in utero. We report a case of fetal hypothyroid goiter secondary to inadvertent excess maternal iodine ingestion from infertility supplements. The fetus was successfully treated with intra-amniotic levothyroxine injections. Serial fetal blood sampling confirmed fetal escape from the Wolff-Chaikoff effect in the mid third trimester. Early hearing test and neurodevelopmental milestones were normal. Intra-amniotic treatment of fetal hypothyroidism may decrease the rate of impaired neurodevelopment and sensorineural hearing loss. © 2018 S. Karger AG, Basel.

To report a rare case of synchronous marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) signet ring cell carcinoma occurring as a collision tumour in the stomach. A 53-year-old man was diagnosed initially with signet ring cell carcinoma of the stomach. The microscopy of the subsequent total gastrectomy revealed a collision tumour of MALT lymphoma and signet ring cell carcinoma associated with Helicobacter pylori gastritis. This case highlighted the importance of a careful evaluation of the accompanying lymphoid population in the biopsy samples of gastric adenocarcinoma and underlined the need for multiple endoscopic biopsies to detect these rare synchronous tumours. © 2013 S.

2015-01-01

Submandibular gland transfer has been widely used to prevent postradiation xerostomia in head-and-neck cancers. However, there are still some controversies. Six databases were searched, data extraction was performed and the risk of bias was assessed by 2 reviewers independently. The meta-analysis was performed using Review Manager, version 5.2. A total of 7 trials (12 articles) and 369 participants were included. The present clinical evidence suggests that submandibular gland transfer might be highly effective to prevent postradiation xerostomia in head-and-neck cancers without serious adverse events. However, more randomized controlled trials are still needed to confirm this conclusion. © 2015 S. Karger AG, Basel.

2014-01-01

In ancient medicine, cannabis has been widely used to cure disturbances and inflammation of the bowel. A recent clinical study now shows that the medicinal plant Cannabis sativa has lived up to expectations and proved to be highly efficient in cases of inflammatory bowel diseases. In a prospective placebo-controlled study, it has been shown what has been largely anticipated from anecdotal reports, i.e. that cannabis produces significant clinical benefits in patients with Crohn's disease. The mechanisms involved are not yet clear but most likely include peripheral actions on cannabinoid receptors 1 and 2, and may also include central actions. © 2013 S. Karger AG, Basel.

To report a rare presentation of necrotizing fasciitis (NF) in the breast and its management. A 61-year-old non-diabetic lady presented with a painful swollen right breast and yellowish discharge associated with fever for the last few days. Based on clinical examination and haematological parameters, a provisional diagnosis of breast abscess was made that later proved to be a case of NF. She was managed conservatively with repeated debridement followed by split-skin grafting with preservation of the breast. This case showed that NF of the breast can present as a simple breast abscess which was managed conservatively. Copyright © 2011 S. Karger AG, Basel.

2018-06-06

Due to the progressive shortage of donors, kidneys with congenital anomalies are considered for transplantation. We report a successful transplantation of a split horseshoe kidney from a deceased donor by using the inferior epigastric artery with an end-to-end anastomosis, supplying the isthmus. Thus, we preserved as much as possible the functional parenchyma for a good long-term outcome. The learning point is that the use of the right inferior epigastric artery seems to be a good solution to perfuse the lower artery in order to avoid its ligation, thus reducing the nephron mass of the graft. © 2018 S.

Fedorak, Richard N; Ismond, Kathleen P

2016-01-01

The inflammatory bowel diseases, Crohn's and ulcerative colitis, have been treated with a range of antibiotics for inducing and maintaining remission, as well as the prevention of post-operative symptoms. To date, many studies have been performed assessing the efficacy of antibiotics when used alone, in combination with other antibiotics, or as an adjunctive therapy to other pharmaceutical treatments. Literature evidence supporting the use of antibiotics in IBD can be ambiguous, especially when considering the potential role of dysbiosis in the gastrointestinal tract. The review considers the systemic effect of antibiotics and the evidence base for their efficacy in the treatment of IBD. © 2016 S. Karger AG, Basel.

Aquaculture is one of the fastest rising sectors of world food production. Hundreds of fish species are cultured, providing an affordable, high quality food source. Two aspects of sexual development are critically important for the continued improvement of cultured fish stocks: sexual dimorphism and control of reproduction. In this paper, we review the main methods used to control sex determination in fish and their application in some of the most widely cultured species. Specifically, we review the techniques available for the production of all-male, all-female, and sterile populations. Techniques for endocrinological control of reproduction are also discussed. 2009 S. Karger AG, Basel.

Itch Management: General Principles.

Misery, Laurent

2016-01-01

Like pain, itch is a challenging condition that needs to be managed. Within this setting, the first principle of itch management is to get an appropriate diagnosis to perform an etiology-oriented therapy. In several cases it is not possible to treat the cause, the etiology is undetermined, there are several causes, or the etiological treatment is not effective enough to alleviate itch completely. This is also why there is need for symptomatic treatment. In all patients, psychological support and associated pragmatic measures might be helpful. General principles and guidelines are required, yet patient-centered individual care remains fundamental. © 2016 S. Karger AG, Basel.

Recent advances in fertility preservation (FP) techniques have led to a wide spread of indications. FP should now be discussed not only for young girls having to receive gonadotoxic treatments for cancer, but also for those with genetic or endocrine disorders, as well as benign ovarian diseases at risk of premature ovarian insufficiency. For premenarchal girls, ovarian tissue cryopreservation is still the only available technique. Oocyte cryopreservation after ovarian stimulation could be offered to postmenarchal girls. Whenever possible, the parents and the young patient should be informed of the benefits to be expected, as well as of the risks and limits of FP for children. © 2018 S. Karger AG, Basel.

A case of unilateral, systematized linear hair follicle nevi associated with epidermal nevus-like lesions.

2003-01-01

Multiple hair follicle nevi are an extremely rare condition. In 1998, a case of unilateral multiple hair follicle nevi, ipsilateral alopecia and ipsilateral leptomeningeal angiomatosis of the brain was first reported from Japan. Very recently, hair follicle nevus in a distribution following Blaschko's lines has also been reported. In this paper, we observed a congenital case of unilateral, systematized linear hair follicle nevi associated with congenital, ipsilateral, multiple plaque lesions resembling epidermal nevi but lacking leptomeningeal angiomatosis of the brain. These cases implicate the possibility of a novel neurocutaneous syndrome. Additional cases should be sought in order to determine whether this condition is pathophysiologically distinct.

Evidence of leopard predation on bonobos (Pan paniscus).

PubMed

D'Amour, Danielle E; Hohmann, Gottfried; Fruth, Barbara

2006-01-01

Current models of social organization assume that predation is one of the major forces that promotes group living in diurnal primates. As large body size renders some protection against predators, gregariousness of great apes and other large primate species is usually related to other parameters. The low frequency of observed cases of nonhuman predation on great apes seems to support this assumption. However, recent efforts to study potential predator species have increasingly accumulated direct and indirect evidence of predation by leopards (Panthera pardus) on chimpanzees and gorillas. The following report provides the first evidence of predation by a leopard on bonobos (Pan paniscus). Copyright 2006 S. Karger AG, Basel.

Handedness in captive bonobos (Pan paniscus).

PubMed

Harrison, Rebecca M; Nystrom, Pia

2008-01-01

Species level right-handedness is often considered to be unique to humans. Handedness is held to be interrelated to our language ability and has been used as a means of tracing the evolution of language. Here we examine handedness in 3 captive groups of bonobos (Pan paniscus) comprising 22 individuals. We found no evidence for species level handedness. Conclusions that can be drawn from these findings are: (1) species level handedness evolved after the divergence of the Pan and Homo lineages; (2) inconsistent preferences may represent precursors to human handedness, and (3) Pan may have language abilities but these cannot be measured using handedness.

The approach to the case is shown from a medico-legal point of view. It is demonstrated how, after a thorough review of the literature, this was not a case of medical malpractice but an unforeseeable event. This paper aims at contributing to the very few reports dealing with the onset of hemidiaphragm paralysis after RARP, thus fostering clinical knowledge of these rare events and meanwhile providing useful data for the medico-legal handling in case of alleged negligence of surgeons. © 2015 S.

Bennett, Derrick A

2010-01-01

There are several examples in the medical literature where the associations of treatment effects predicted by observational studies have been refuted by evidence from subsequent large-scale randomised trials. This is because of the fact that non-experimental studies are subject to confounding - and confounding cannot be entirely eliminated even if all known confounders have been measured in the study as there may be unknown confounders. The aim of this 2-part methodological primer is to introduce an emerging methodology for estimating treatment effects using observational data in the absence of good randomised evidence known as the method of instrumental variables.

2005-01-01

The demonstration of an underlying prothrombotic condition in cerebral venous thrombosis (CVT) may have important practical consequences in terms of prevention. Thyrotoxicosis through a hypercoagulable state may be a predisposing factor for CVT. The authors present the cases of 4 patients who developed CVT and hyperthyroidism. At the acute stage, hyperthyroidism was associated with an increase in factor VIII (FVIII). At follow-up, FVIII level remained increased in 2 patients. Hyperthyroidism may have an impact on FVIII level. Accordingly in patients with hyperthyroidism and neurological symptoms, the diagnosis of CVT should be considered and an exhaustive coagulation screening may be appropriate. (c) 2005 S.

Myofibroblasts, cells with both fibroblastic and smooth muscle cell features, have been implicated in renal scarring. In addition to synthetic properties, contractile features and integrin expression may allow myofibroblasts to rearrange and contract interstitial collagenous proteins. Myofibroblasts from normal rat kidneys were grown in cell-populated collagen lattices to measure cell generated contraction. Following detachment of cell populated collagen lattices, myofibroblasts progressively contracted collagen lattices, reducing lattice diameter by 42% at 24 h. Alignment of myofibroblasts, rearrangement of fibrils and beta(1) integrin expression were observed within lattices. We postulate that interstitial myofibroblasts contribute to renal scarring through manipulation of collagenous proteins. Copyright 1999 S. Karger AG, Basel

We calculated the population density of the critically endangered Callicebus oenanthe in the Ojos de Agua Conservation Concession, a dry forest area in the department of San Martin, Peru. Results showed significant differences (p < 0.01) in group densities between forest boundaries (16.5 groups/km2, IQR = 21.1-11.0) and forest interior (4.0 groups/km2, IQR = 5.0-0.0), suggesting the 2,550-ha area harbours roughly 1,150 titi monkeys. This makes Ojos de Agua an important cornerstone in the conservation of the species, because it is one of the largest protected areas where the species occurs. © 2016 S. Karger AG, Basel.

Recent reports have advocated treatment of congenital chylothorax with chemical pleurodesis via intrapleural administration of OK-432. Severe complications have not been reported, but recently we have encountered a life-threatening case of massive hemolysis after the procedure. The hemoglobin of the infant decreased from 8.7 to 3.1 g/dl within 48 h, with concomitant severe hyperbilirubinemia (472 μmol/l) requiring exchange transfusion. Frontline neonatologists should be aware of this rare but potentially life-threatening adverse reaction. In addition, it is possible that a longer indwelling time (3.5 vs. 0.5 h) for OK-432 pleurodesis may alter the therapeutic response. © 2016 S. Karger AG, Basel.

Effects of various vehicles on skin hydration in vivo.

The stratum corneum, the outermost layer of the skin, regulates the passive loss of water to the environment. Furthermore, it is well accepted that drug penetration is influenced by skin hydration, which may be manipulated by the application of moisturizing or oleaginous vehicles. Measurements of transepidermal water loss (TEWL), and of skin hydration using a corneometer, were used to assess the effect of different vehicles on stratum corneum barrier function in vivo in human volunteers. A microemulsion significantly increased skin hydration relative to a reference vehicle based on medium chain triglycerides; in contrast, Transcutol(R) lowered skin hydration. TEWL measurements confirmed these observations. Copyright 2009 S. Karger AG, Basel.

Non-breast milk feeding in developing countries: challenge from microbial and chemical contaminants.

PubMed

Weisstaub, Gerardo; Uauy, Ricardo

2012-01-01

Complementary foods based on cow's milk or gruels consumed by children in developing countries are often contaminated by bacteria during preparation, and ambient temperature rapidly increases microbial load. Thus infant formula or other weaning foods may cause diarrhea in young infants accounting for 25-33% of all deaths <5 years globally. Environmental chemicals such as metals (As, Pb, Cu) and nitrates can cause vomiting/diarrhea. Polychlorinated biphenyls derived from plastics, present in formula and/or breast milk, are endocrine disruptors (the potential threats are not fully quantifiable). The prevailing view is that benefits from breastfeeding outweigh potential risks. Copyright © 2012 S. Karger AG, Basel.

Krutak, Lars

2015-01-01

For millennia, peoples around the world have tattooed human skin to communicate various ontological, psychosocial, and sociocultural concepts encompassing beauty, cultural identity, status and position, medicine, and supernatural protection. As a system of knowledge transmission, tattooing has been and continues to be a visual language of the skin whereby culture is inscribed, experienced, and preserved in a myriad of specific ways. If we are to fully comprehend the meanings that tattoos have carried across human history and into the present, then it would be useful to explore some of the ways tattoos, as instruments that transmit culture, have been deployed cross-culturally through time. © 2015 S.

Bialobrzeski, A; Ried, J; Dabrock, P

2012-01-01

The notions 'common good' and 'public good' are mostly used as synonyms in bioethical discussion of biobanks, but have different origins. As a consequence, they should be applied differently. In this article, the respective characteristics are worked out and then subsequently examined which consent models emerge from them. Distinguishing normative and descriptive traits of both concepts, it turns out that one concept is unjustly used, and that the other one fits better to the context of a plural society. A reflected use of these differing concepts may help to choose an appropriate form of consent and allows public trust in biobank research to deepen. Copyright © 2012 S. Karger AG, Basel.

Vowel Height Allophony and Dorsal Place Contrasts in Cochabamba Quechua.

Gallagher, Gillian

2016-01-01

This paper reports on the results of two studies investigating the role of allophony in cueing phonemic contrasts. In Cochabamba Quechua, the uvularvelar place distinction is often cued by additional differences in the height of the surrounding vowels. An acoustic study documents the lowering effect of a preceding tautomorphemic or a following heteromorphemic uvular on the high vowels /i u/. A discrimination study finds that vowel height is a significant cue to the velar-uvular place contrast. These findings support a view of contrasts as collections of distinguishing properties, as opposed to oppositions in a single distinctive feature. © 2016 S. Karger AG, Basel.

As to the arrangement of materials and instruments on the surgical table, fluids that must not be introduced intraocularly, infusion fluid for washing the ocular surface, fluids for intraocular injection, and fluids for periocular injection are classified and marked to avoid using the wrong fluid. Since bacteria are present in the fluid retained in the fluid catch bag, the accumulated infusion fluid should be removed by aspiration. © 2014 S. Karger AG, Basel

Bachelor's, master's and PhD programs in the field of pure logopedics no longer exist in some countries. In other locations, logopedics is included as a part of special education student training. In all cases, student education in logopedics is centralized in the universities. Educational programs are accredited by national agencies for accreditation or evaluation or by the respective Ministries of Education. 2010 S. Karger AG, Basel.

Leo Schnug: alcoholic dementia as an unexpected source of inspiration for an artist.

PubMed

Sellal, François

2011-01-01

Artistic creativity can be defined as the ability to challenge established academic representations or tastes, and to produce both innovative and esthetic works. Here, we investigate the influence of alcoholic dementia on creativity by describing the case of the famous painter Leo Schnug. It is clear that Schnug's motor and psychic disorders had a dramatic influence on his late artistic output. His hallucinations, panic attacks and delusions had an influence on both the themes and the personal, expressionistic and easily recognizable style of his work. It is unlikely that he would have attained these had he been in good health. Copyright © 2011 S. Karger AG, Basel.

2013-01-01

White-eyelid mangabeys (genus Cercocebus) live in groups of highly variable size. Because of their semi-terrestrial behaviour and preference for dense forest habitats, re-liable data on group size are scarce. During a 5-month study, we collected 17 group counts on a habituated group of agile mangabeys (C. agilis) at Bai Hokou in the Central African Republic. We found a stable group size of approximately 135 individuals. This permanent large grouping pattern is known to occur among several populations of white-eyelid mangabeys and is congruent with extreme group sizes reported in mandrills at Lopé in Gabon.

This study aimed to assess the influence of an adapted physical activity program on self-esteem and quality of life in breast cancer patients. Twenty-three women diagnosed with breast cancer and treated by mastectomy formed 2 groups. The experimental group practiced adapted physical activity for 12 weeks, while the control group did not. All participants answered questionnaires regarding their self-esteem and quality of life at the beginning of the program and 6 and 12 weeks after that. Self-esteem, physical self-perception, quality of life, global health status, pain, and breast symptoms were improved only in the group which practiced adapted physical activity. © 2018 S.

2018-06-13

Spontaneously hypertensive rats (SHR) represent a model of essential hypertension. We studied the effect of amlodipine (AML) on bone markers, bone mineral density (BMD), and biomechanical properties of osteopenic bone induced by orchidectomy in male SHR. Rats were allocated to 3 groups and were sacrificed after 12 weeks: sham-operated control; orchidectomised control; and orchidectomised receiving a diet supplemented with AML. Indicators of bone turnover were assessed in bone homogenate, BMD was measured by dual energy X-ray absorptiometry, and the femurs were subjected to biomechanical testing. Long-term AML administration does not have a negative impact on bone metabolism and density in male SHR. © 2018 S. Karger AG, Basel.

The Effects of Climate Change on Cardiac Health.

De Blois, Jonathan; Kjellstrom, Tord; Agewall, Stefan; Ezekowitz, Justin A; Armstrong, Paul W; Atar, Dan

2015-01-01

The earth's climate is changing and increasing ambient heat levels are emerging in large areas of the world. An important cause of this change is the anthropogenic emission of greenhouse gases. Climate changes have a variety of negative effects on health, including cardiac health. People with pre-existing medical conditions such as cardiovascular disease (including heart failure), people carrying out physically demanding work and the elderly are particularly vulnerable. This review evaluates the evidence base for the cardiac health consequences of climate conditions, with particular reference to increasing heat exposure, and it also explores the potential further implications. © 2015 S.

2018-01-01

Small remnants of the right valve of the sinus venosus are commonly found in adults, but the incidence and risk associated with these embryonic remnants in neonates are not well studied. The following report describes a cyanotic neonate with a large Eustachian valve remnant creating a functional cor triatriatum dexter who was initially diagnosed with persistent pulmonary hypertension of the newborn. The cyanosis in this infant improved over the first postnatal week with conservative management, but she suffered multifocal subcortical stroke, likely related to her intracardiac shunt. The clinical presentation and questions regarding long-term management of this rare diagnosis are explored. © 2018 S. Karger AG, Basel.

Breakdown of the balanced lethals in Rhoeo: the structure of the Alethal Renner complex of the homozygotic stock of Rhoeo.

PubMed

Golczyk, H

2011-01-01

Fluorescence in situ hybridization, base-specific fluorescence, C-banding and silver-staining were performed to reveal the cyto-molecular constitution of the karyotype in the bivalent-forming Rhoeo spathacea concolor. It was shown that the genome of this form is almost identical to the β-complex of the ring-forming rhoeos. In spite of some modifications in the arrangement of a few distal rDNA sites and in the amount of pericentromeric AT-rich heterochromatin, the alethal genome of the bivalent-forming Rhoeo seems segmentally unaltered. Thus, the breakdown of balanced lethals in Rhoeo is most likely uncoupled from creating new chromosome arm combinations. Copyright © 2011 S. Karger AG, Basel.

A hermeneutic framework for psychopathology.

PubMed

Stanghellini, Giovanni

2010-01-01

After briefly reviewing the scope and limitations of descriptive and clinical psychopathology, this paper focuses on the method and intention of structural psychopathology. Structural psychopathology goes beyond the description of isolated symptoms and the use of some of those symptoms to establish a diagnosis. It aims to understand the meaning of a given world of experiences and actions grasping the underlying characteristic modification that keeps the symptoms meaningfully interconnected. Building on and expanding some basic phenomenological and hermeneutical principles, and applying them to the study of abnormal human subjectivity, this paper suggests the methodological guidelines for a structurally informed psychopathological interview.

2018-06-01

To describe the current hospital pharmacy practice in Saudi Arabia according to the revised Basel statements. A review of the available data based on published literature in the subject area was carried out. The original Basel Statements were developed at the 2008 Global Conference on the Future of Hospital Pharmacy in Basel, Switzerland. Representatives from 98 countries, including Saudi Arabia, attended this conference. The revision of the Basel statements simplified and merged many of the original Basel statements. In addition to making the Basel statements more concise, the revision added new statements to reflect global trends and the expanded responsibilities of hospital pharmacists. The release of the Basel statements represents an important opportunity to bring Saudi Arabian practices into complete concurrence with international standards and to identify areas that should be prioritized. © 2017 Royal Pharmaceutical Society.

Mammalian follicular development and atresia: role of apoptosis.

PubMed

Asselin, E; Xiao, C W; Wang, Y F; Tsang, B K

2000-01-01

The regulation of follicular development and atresia is a complex process and involves interactions between endocrine factors (gonadotropins) and intraovarian regulators (sex steroids, growth factors and cytokines) in the control of follicular cell fate (i.e. proliferation, differentiation and programmed cell death). Granulosa and theca cells are key players in this fascinating process. As atresia is the fate of most follicles, understanding of how these physiological regulators participate in determining the destiny of the follicle (to degenerate or to ovulate) at cellular and subcellular levels is fundamental. This short review summarizes the role of intraovarian modulators of programmed cell death in the induction of atresia during follicular development. Copyright 2000 S. Karger AG, Basel

2010-01-01

Basal cell carcinoma (BCC), the most prevalent form of cancer worldwide, is a malignant skin neoplasm. It is locally invasive, with an exceptional incidence of reported metastasis. It can also be part of the Gorlin-Goltz syndrome, an autosomal dominant genetic disorder with high penetrance and variable expressivity, which is principally characterized by cutaneous BCC, odontogenic keratocysts, palmar and/or plantar pits, and falx cerebri calcification. We report the exceptional clinical observation of a 54-year-old man presenting bone metastasis from BCC in Gorlin-Goltz syndrome. Less than 300 cases of metastatic BCC have been reported in the literature. The present case is the second associated with Gorlin-Goltz syndrome. Copyright 2009 S. Karger AG, Basel.

Rhythm as an affordance for the entrainment of movement.

PubMed

Cummins, Fred

2009-01-01

A general account of rhythm in human behaviour is provided, according to which rhythm inheres in the affordance that a signal provides for the entrainment of movement on the part of a perceiver. This generic account is supported by an explication of the central concepts of affordance and entrainment. When viewed in this light, rhythm appears as the correct explanandum to account for coordinated behaviour in a wide variety of situations, including such core senses as dance and the production of music. Speech may appear to be only marginally rhythmical under such an account, but several experimental studies reveal that speech, too, has the potential to entrain movement. (c) 2009 S.

One of the components of the Mini Mental State Examination (MMSE) is the request to write a sentence. We investigated the relationship between the characteristics of the written sentence of the MMSE and the cognitive and affective status of elderly patients. The characteristics of the sentence were compared to the total MMSE score, sociodemographic characteristics, tests evaluating cognition and affective status, and diagnoses. The number of words was significantly associated with the degree of cognitive impairment, whereas the emotional polarity of sentences and concerns about health were associated with depression. Characteristics of the MMSE sentence may provide important additional information regarding both cognition and affect when assessing older people. Copyright © 2012 S. Karger AG, Basel.

The evaluation of the characteristics of the fetal stomach should be part of every routine prenatal ultrasound after 11 weeks. A position that has not been previously described in the literature is the stomach in contact with the bladder. We describe 6 cases with the ultrasonographic finding of the stomach in contact with the bladder, all of them in fetuses with left-sided congenital diaphragmatic hernia. Even though the reasons for this striking position of the stomach are not clear, our series highlights the fact that the visualization of the stomach in contact with the bladder may be a specific sonographic marker of congenital diaphragmatic hernia. © 2015 S.

Developing neurons synthesize substantial quantities of membrane phospholipids in producing new synapses. We investigated the effects of maternal uridine (as uridine-5'-monophosphate) and docosahexaenoic acid supplementation on pups' brain phospholipids, synaptic proteins and dendritic spine densities. Dams consumed neither, 1 or both compounds for 10 days before parturition and 20 days while nursing. By day 21, brains of weanlings receiving both exhibited significant increases in membrane phosphatides, various pre- and postsynaptic proteins (synapsin-1, mGluR1, PSD-95), and in hippocampal dendritic spine densities. Administering these phosphatide precursors to lactating mothers or infants could be useful for treating developmental disorders characterized by deficient synapses. 2009 S. Karger AG, Basel.

The advent of anti-VEGF therapy for neovascular age-related macular degeneration and macular edema secondary to retinal vein occlusion and diabetes mellitus has prevented blindness in tens of thousands of people. However, the costs of these drugs are without precedent in ophthalmic drug therapeutics. An analysis of the financial implications of retinal drugs and the impact of the Food and Drug Administration on treatment of retinal disease must include not only an evaluation of the direct costs of the drugs and the costs associated with their administration, but also the cost savings which accrue from their clinical benefit. This chapter will discuss the financial and regulatory issues associated with retinal drugs. © 2016 S. Karger AG, Basel.

Innate immunity is a rapidly evolving field with novel cell types and molecular pathways being discovered and paradigms changing continuously. Innate and adaptive immune responses are traditionally viewed as separate from each other, but emerging evidence suggests that they overlap and mutually interact. Recently discovered cell types, particularly innate lymphoid cells and myeloid-derived suppressor cells, are gaining increasing attention. Here, we summarize and highlight current concepts in the field, focusing on innate immune cells as well as the inflammasome and DNA sensing which appear to be critical for the activation and orchestration of innate immunity, and may provide novel therapeutic opportunities for treating autoimmune, autoinflammatory, and infectious diseases. © 2016 S.

There is no other sport that has come under greater scrutiny surrounding the incidence and treatment of concussion than football, and there is no other professional sports league that has experienced more intense focus of its handling of concussions than the National Football League (NFL). The NFL has received significant criticism of their management of concussion in players from both the popular press and the medical community. However, those working with active NFL players have changed their assessment and treatment of these injuries as the knowledge of concussions has evolved over time. We review the current approach to the management of concussions in the professional football player. © 2014 S. Karger AG, Basel.

Primary Ewing's Sarcoma/Primitive Neuroectodermal Tumor of Kidney with Caval Involvement in a Pregnant Woman.

In this article, we report the case of a woman in whom was found an abdominal mass during pregnancy and who underwent nephrectomy and extraction of the emboli after delivery. The kidney had a volume of 15 × 10 × 8 cm and pathological diagnosis was primary Ewing's sarcoma. The patient was treated with conventional chemotherapy for 1 year after surgery, at which time multiple metastases were found. From this case, we surmise that hormonal changes that occur during pregnancy may accelerate the growth of Ewing's sarcoma of the kidney, suggesting that renal tumors in pregnant women demand serious attention and that anti-cancer treatment should begin as soon as possible. © 2016 S.

The effect of opium on the creativity and productivity of a famous composer of classical music, an essayist, and poets including Hector Berlioz, Thomas De Quincy, Samuel Taylor Coleridge, John Keats, and Jean Cocteau, is described. Opium is a narcotic drug prepared from the juice of the unripe seed capsules of the opium poppy. It contains alkaloids such as morphine, codeine, and papaverine. Medically it is used to relieve pain and produce sleep. It is used as an intoxicant. Alcohol and opium were commonly relied on in the 19th century, especially by artists, to stimulate creativity and relieve stress. These artists described the effect of opium on their creativity and productivity. Copyright (c) 2010 S. Karger AG, Basel.

Aspergillus Vertebral Osteomyelitis Complicating Pulmonary Granuloma in an Immunocompetent Adult.

Li, Yun; Cen, Yanyi; Luo, Yuwen; Zhu, Zhe; Min, Shaoxiong; Chen, Xin

The aim of this report is to describe a case with Aspergillus vertebral osteomyelitis complicating pulmonary granuloma in an immunocompetent adult. A 53-year-old male patient was found to have lesions on lumbar vertebra 5 months after thoracoscopic resection of pulmonary granuloma that lacked a definite etiology. Three operations on the lumbar lesions were performed successively; however, an Aspergillus infection was not confirmed until hyphae were clearly detected at the last surgery. The patient was treated with voriconazole and recovered well. This case shows that simultaneous occurrence of granulomatous nodules in the lung and vertebral lesions should raise suspicion of aspergillosis, even in immunocompetent patients. © 2015 S.

Previously an increased frequency of KIT aberrations in mucosal melanomas was reported, whereas c-KIT in most types of cutaneous melanomas does not appear to be of pathogenetic importance. Imatinib has become the standard of care in other cancers with KIT mutations such as gastrointestinal stromal tumors. Recently 12 cases of metastatic melanoma and KIT-activating mutations have been published to be successfully treated with c-KIT blockers such as imatinib, sunitinib, dasatinib or sorafenib. We report here on one of our patients with KIT-activating mutation in metastatic anal mucosal melanoma, who showed a response to imatinib therapy and summarize the available literature regarding this new therapeutic option.

Fetus-in-fetu is a rare congenital fetiform mass whose etiology is still controversial. We report two cases of fetus-in-fetu. CASE 1: A fetal retroperitoneal cystic tumor including two masses was detected by ultrasonography at 26 gestational weeks. The masses showed distinctive structures resembling a vertebral axis and were prenatally diagnosed as fetus-in-fetu. A resected specimen revealed two fetiform masses. CASE 2: An intracranial tumor with hydrocephalus was detected by ultrasonography at 19 gestational weeks. The pregnancy was terminated, and a postmortem examination revealed six fetiform masses with immature teratoma. The tumors may possibly consist of parasitic monozygotic diamniotic twins or highly differentiated teratomas. Copyright 2007 S. Karger AG, Basel.

The growth of digital methods in pathology is accelerating. Digital images can be used for a variety of applications in cytology, including rapid interpretations, primary diagnosis and second opinions, continuing education and proficiency testing. All of these functions can be performed using small static digital images, real-time dynamic digital microscopy, or whole-slide images. This review will discuss the general principles of digital pathology, its methods and applications to cytologic specimens. As cytologic specimens have unique features compared to histopathology specimens, the key differences will be discussed.

Precision medicine and personalized medicine are based on the development of biomarkers, and liquid biopsy has been reported to be able to detect biomarkers that carry information on tumor development and progression. Compared with traditional 'solid biopsy', which cannot always be performed to determine tumor dynamics, liquid biopsy has notable advantages in that it is a noninvasive modality that can provide diagnostic and prognostic information prior to treatment, during treatment and during progression. In this review, we describe the source, characteristics, technology for detection and current situation of circulating tumor cells, circulating free DNA and exosomes used for diagnosis, recurrence monitoring, prognosis assessment and medication planning. © 2017 The Author(s)Published by S.

We describe a peculiar and relatively rare type of chromosomal rearrangement induced in human peripheral lymphocytes that were ostensibly irradiated in G(0) phase of the cell cycle by accelerated heavy ions, and which, to the best of our knowledge, have not been previously described. The novel rearrangements which were detected using mFISH following exposure to 500 MeV/nucleon and 5 GeV/n 56Fe particles, but were not induced by either 137Cs gamma rays or 238Pu alpha particles, can alternatively be described as either complex chromatid-isochromatid or complex chromatid-chromosome exchanges. Different mechanisms potentially responsible for their formation are discussed. Copyright 2003 S. Karger AG, Basel

2001-01-01

The clinical features of Coats' disease and congenital retinoschisis (RS) are distinctly different. Therefore, finding changes consistent with Coats' disease and congenital RS in a single eye is an unusual occurrence. The following report describes two cases with a Coats' telangiectatic lesion in one region of the retina separated by normal retina and the presence of central and peripheral congenital RS. Molecular genetic analysis of the Norrie disease and RS genes failed to identify disease-causing or polymorphic mutations in either of the genes, suggesting that the above condition is clinically and genetically a different disorder. Further studies are needed to identify the genes responsible for the above disorder and associated ocular manifestations. Copyright 2001 S. Karger AG, Basel.

Equine recurrent uveitis (ERU) is an autoimmune disease that occurs with a high prevalence (10%) in horses. ERU represents the only reliable spontaneous model for human autoimmune uveitis. We already identified and characterized novel autoantigens (malate dehydrogenase, recoverin, CRALBP) by analyzing the autoantibody-binding pattern of horses affected by spontaneous recurrent uveitis (ERU) to the retinal proteome. CRALBP also seems to be relevant to human autoimmune uveitis. Proteomic screening of vitreous and retinal samples from ERU diseased cases in comparison to healthy controls has led to the identification of a series of differentially regulated proteins, which are functionally linked to the immune system and the maintenance of the blood-retinal barrier. 2008 S.

Several studies have linked massively multiplayer online role-playing games (MMORPGs) with possible problematic usage or internet addiction. The main goal of the present study was to assess links between motivations to play in MMORPGs and addictive involvement in such types of games. A total of 696 gamers responded to an online survey. Five distinct motivations to play were identified in gamers: achievement, socializing, immersion, relaxing and escaping. Multiple regression analysis revealed that addictive MMORPG use patterns are predicted by achievement, escapism and socializing motives. Gender was also a significant predictor of problematic involvement in MMORPGs. Moreover, addictive MMORPG use positively correlated with the weekly time devoted to playing MMORPGs.

2008-01-01

In order to characterize the receptor binding pharmacology of CJ-023,423, a potent and selective EP4 antagonist, we performed a radioligand receptor binding assay under various assay conditions. An acidic (pH 6) and hypotonic buffer is a conventional, well-known buffer for prostaglandin E2 receptor binding assays. CJ-023,423 showed moderate binding affinity for human EP4 receptor under conventional buffer conditions. However, its binding affinity was greatly increased under neutral (pH 7.4) and isotonic buffer conditions. In this report, the binding mechanism between CJ-023,423 and human EP4 receptor is discussed based on the binding affinities determined under various assay conditions. Copyright 2008 S.

Medical ethics: a rational approach to patient management.

Livadas, Gerry

2002-01-01

Physicians make their decisions based upon scientific evidence with their first consideration being the Hippocratic axiom 'not to do harm'. In practice, a number of non-medical issues influence this process and generate conflicting judgments. We analyze these issues that form the context of medical ethics which is perceived as a subject wider than morality. It is also a religious, social, political, economic, legal and cultural issue. Therefore, the patient, physician and other professionals play important roles in the decision-making. The final decision is not a decision based on medical textbooks, but is rational in that it is based on reason for the benefit of the individual. Copyright 2002 S. Karger AG, Basel

Medical Overtreatment: Friend or Foe?

PubMed

Hadler, Nortin M

2018-01-01

"Overtreatment" is a neologism coined some 15 years ago to denote medical and surgical interventions that are unnecessary. It is a topical term for an old concept. However, it has rapidly become a shibboleth for those inclined toward finger-pointing and blaming in matters of health policy. As such, it is a "foe" that heats up rather than modulates debate. But if one examines the notion in the context of the contemporary patient-physician dialogue, it is anything but a foe. Overtreatment and its fellow travelers, overutilization and overprescription, face off with contrary notions when a patient contends with the challenge of evaluating any clinical option. © 2018 S.

2008-01-01

Population-based estimates of biological family size can be useful for planning genetic studies, assessing how distributions of relatives affect disease associations with family history and estimating prevalence of potential family support. Mean family size per person is estimated from a population-based telephone survey (n = 1,019). After multivariate adjustment for demographic variables, older and non-White respondents reported greater mean numbers of total, first- and second-degree relatives. Females reported more total and first-degree relatives, while less educated respondents reported more second-degree relatives. Demographic differences in family size have implications for genetic research. Therefore, periodic collection of family structure data in representative populations would be useful. Copyright 2008 S.

Acne is a common skin disorder that can be problematic for adults as well as for adolescents. It has several key pathophysiological features such as follicular hyperkeratosis, elevated Propionibacterium acnes proliferation, and reactive inflammation, all of which should be targeted for an optimal outcome. Azelaic acid (AzA) has profound anti-inflammatory, antioxidative effects, and is bactericidal against a range of Gram-negative and Gram-positive microorganisms as well, including antibiotic-resistant bacterial strains. In addition, AzA's antikeratinizing effects are inhibitory toward comedones. AzA is effective overall in targeting multiple causes of acne and has been proven to be well tolerated in numerous clinical trials. © 2013 S. Karger AG, Basel.

The great French organist and composer Louis Vierne (1870-1937) died while performing an organ recital at Notre Dame cathedral in Paris - right in front of the console. This historical article provides insights into the biography of a highly talented musician who was challenged by disability and diseases throughout his career. A special focus is placed on the circumstances of Vierne's remarkable death. Until now, both a primary cerebrovascular event and a 'heart attack' are discussed in reference books and encyclopedias as the immanent causes of death. From the perspective of a stroke neurologist, a reappraisal of Vierne's medical history and the events that happened during his last concert is presented. Copyright © 2012 S. Karger AG, Basel.

Ingenol Mebutate for Recalcitrant Chronic Actinic Cheilitis.

We present the case of a healthy 76-year-old man with a whitish, hyperkeratotic lesion of the lower lip diagnosed as actinic cheilitis (AC) previously treated with classic red light photodynamic therapy 5 years ago. Initial treatment with 5% imiquimod cream - also with intensified application - failed. After 2 cycles thrice daily, consecutive applications of 150 μg/g ingenol mebutate gel at 3 weeks' interval, the lesions cleared completely. Surprisingly, no pustular or crusting reaction or other side effect occurred contrary to expectation. Remission was stable for 10 months, when recurrence occurred. Ingenol mebutate proved to be a feasible and safe treatment in this otherwise refractory case of AC. © 2016 S. Karger AG, Basel.

A rational approach to the selection of useful drugs for clinical practice.

PubMed

Spector, Reynold; Vesell, Elliot S

2002-05-01

Confusion exists concerning optimal selection of drugs for clinical practice. Many reasons contribute to this confusion which derives from various sources including industry, the FDA and often less than ideal education of physicians in clinical pharmacology during medical school and thereafter. This presentation does not focus on allocating blame for the current unsatisfactory situation, but rather offers a solution to improve drug therapy. Our educational solution consists of a paradigm for rational drug therapy, specifically a checklist of eight criteria for physicians to review before prescribing drugs. Such a review would facilitate better estimation by physicians of risk/benefit ratios involving new, often expensive and, in some cases, questionably effective and safe drugs. Copyright 2002 S.

Trypanosoma cruzi: in vitro morphological alterations induced by actinomycin D.

PubMed

2003-02-01

Actinomycin (ActD) is an antibiotic that binds DNA, preventing transcription. When a Trypanosoma cruzi infection in mice is treated with this drug, the parasite loses its ability to multiply, enabling protection. In this study, axenic cultured T. cruzi parasites were exposed to different concentrations of ActD (10, 20, and 50 microg/ml), all of them being able to inhibit growth and to alter the mobility. Nevertheless, the parasites remained alive and motile for at least 14 days. Scanning electron microscopy of trypomastigotes treated with 10 microg/ml of ActD for 24 h showed a modification in their morphology which suggests a change in the parasite cytoskeleton.

Myostatin and sarcopenia: opportunities and challenges - a mini-review.

PubMed

White, Thomas A; LeBrasseur, Nathan K

2014-01-01

The progressive loss of skeletal muscle mass, strength and/or function with advancing age, termed sarcopenia, poses a major threat to independence and quality of life. Therefore, there is significant merit in better understanding the biology of sarcopenia and developing therapeutic interventions to prevent, slow or reverse its progression. Since the discovery of myostatin, a potent negative regulator of growth that is highly enriched in skeletal muscle, there has been great interest in it as a potential mediator of sarcopenia as well as a therapeutic target. The complex biology of myostatin, the promise of myostatin inhibition as an effective means to counter sarcopenia, and the challenges facing its clinical translation are reviewed herein. © 2014 S.

An explosion of research on mastocytosis in the last decade has witnessed a greater understanding of the molecular basis of this heterogeneous group of disorders and the conclusion that similar disease phenotypes may indeed be the result of different underlying genotypes. Along with our growing knowledge base of mastocytosis, newer approaches of treating these disorders are becoming available, all under investigational use at this time. This short review highlights the state of the art of current treatment strategies for the different categories of mastocytosis. The future will undoubtedly witness an even greater array of therapeutic options, as we continue to learn more about this enigmatic disease. Copyright 2002 S. Karger AG, Basel

Klinefelter's syndrome and Prader-Willi syndrome: a rare combination.

Verhoeven, W M A; de Vries, B B A; Duffels, S J H; Egger, J I M; Noordam, C; Tuinier, S

2007-01-01

In this paper a review is presented of the rare combination of Klinefelter's syndrome and Prader-Willi syndrome (PWS) and a second case of this combination with a uniparental disomy (UPD) etiology of PWS is described. Patients outlined in all other 8 reports and the present case have a PWS phenotype. Virtually no information is available on the behavioral and psychopathological phenotype in this combination. The latter may be explained by the observation that psychiatric syndromes are especially prevalent in PWS patients with a UPD. It is concluded that instability in mood and behavior in this and other syndromes should be preferentially treated with mood stabilizing agents. Copyright (c) 2007 S. Karger AG, Basel.

This study evaluated the acidogenicity of human milk by the dental biofilms of children with and without early childhood caries (ECC). Biofilms of 16 children (7 with ECC; 9 caries free) were exposed to human milk or 10% sucrose solution in the crossover design, and the biofilm pH was determined. Breastfeeding did not provoke a decrease in biofilm pH, irrespective of the children's caries status, whereas sucrose decreased the pH for both groups. In addition, higher x0394;pH5min (pH variation occurring at 5 min) was observed in the biofilms of ECC children (p < 0.05). The results suggest that breastfeeding may not contribute to ECC. © 2016 S.

Lung cancer is currently the leading cause of cancer-related mortality among men and women in the United States, and optimal screening methods are still lacking. The field effect is a well-supported phenomenon wherein a noxious stimulus triggers genetic, epigenetic and molecular changes that are widespread throughout the entire exposed organ system. The buccal epithelium is an easily accessible part of the respiratory tree that has good potential of yielding a surrogate marker for the field effect in cigarette smokers, and thus, a noninvasive, reliable lung cancer screening method. Herein, we review the literature on the relationship between the buccal epithelium, cigarette smoking, and lung cancer. © 2017 S. Karger AG, Basel.

A chromosome inversion near the KIT gene and the Tobiano spotting pattern in horses.

PubMed

Brooks, S A; Lear, T L; Adelson, D L; Bailey, E

2007-01-01

Tobiano is a white spotting pattern in horses caused by a dominant gene, Tobiano(TO). Here, we report TO associated with a large paracentric chromosome inversion on horse chromosome 3. DNA sequences flanking the inversion were identified and a PCR test was developed to detect the inversion. The inversion was only found in horses with the tobiano pattern, including horses with diverse genetic backgrounds, which indicated a common genetic origin thousands of years ago. The inversion does not interrupt any annotated genes, but begins approximately 100 kb downstream of the KIT gene. This inversion may disrupt regulatory sequences for the KIT gene and cause the white spotting pattern. Copyright (c) 2008 S. Karger AG, Basel.

Axenfeld-Rieger syndrome (ARS) is a clinically and genetically heterogeneous group of autosomal dominantly inherited malformations that predominantly affect the eye but are also associated with craniofacial dysmorphism and dental abnormalities. A broad spectrum of genetic alterations involving PITX2 and FOXC1 lead to ARS. We report on a 4-year-old girl with clinical features of ARS and developmental delay due to a de novo apparently balanced pericentric inversion in chromosome 4. This report emphasizes that complementary investigations are necessary to precisely characterize chromosomal rearrangements. Elucidation of the exact genetic cause of ARS is important for comprehensive genetic counseling of the family members and for better patient management. © 2017 S. Karger AG, Basel.

2006-01-01

Understanding the genetic basis of hearing loss is important because almost 50% of profound hearing loss are caused by genetic factors and more than 120 independent genes have been identified. In this review, after a brief explanation of some genetic terms (allele, heterozygosis, homozygosis, polymorphism, genotype and phenotype), classification of genetic hearing loss (syndromic versus nonsyndromic, and recessive dominant, X-linked and mitochondrial) was performed. Some of the most common syndromes (Usher, Pendred, Jervell and Lange-Nielsen, Waardenburg, branchio-oto-renal, Stickler, Treacher Collins and Alport syndromes, biotinidase deficiency and Norrie disease) causing genetic hearing loss were also explained briefly. The genes involved in hearing loss and genetic heterogeneity were presented. Copyright 2006 S. Karger AG, Basel.

Recently, placement of a ventriculoperitoneal shunt via a transumbilical approach has been reported. Herein, we report the repair of an umbilical hernia via the same incision and introduction of the distal end of a ventricultoperitoneal shunt into the peritoneal cavity in 3 patients. A case illustration is included. Both hernia repair and placement of the distal end of the ventriculoperitoneal shunt were uncomplicated in our small case series. To our knowledge, simultaneous repair of an umbilical hernia followed by transumbilical shunt placement has not been reported. As umbilical hernias are so common in infants, this finding, based on our experience, should not exclude placement of peritoneal tubing in the same setting. © 2017 S. Karger AG, Basel.

Psychopathology of the bodily self and the brain: the case of schizophrenia.

In the present paper, we review the recent empirical evidence on the neurobiological basis of a minimal notion of the self, the bodily self. We show the relationship between the body, its motor potentialities and the notion of minimal self. We argue that this approach can shed new light onto self-disturbances and social deficits characterizing schizophrenia. We discuss our approach with other views on the neural correlates of self-disturbances in schizophrenia and propose that cognitive neuroscience can today address the classical topics of psychopathology by adding a new level of description, finally enabling the correlation between the first-person experiential aspects of psychiatric diseases and their neurobiological roots. © 2014 S.

In Brazil, as in the rest of the world, the prevalence of chronic kidney disease (CKD) is increasing. In order to alert the population, health professionals and authorities to this risk, in 2003, the Brazilian Society of Nephrology launched a CKD prevention campaign called 'Previna-se'. In addition, since its onset, Brazil has participated in the World Kidney Day efforts and has developed several prevention strategies. Here, we summarize the main strategies adopted in this campaign (population screening, events and meetings, distribution of educational materials, routine report of estimated glomerular filtration rate) and our initial results, sharing practical experience that could be useful in other developing countries.

Postoperative intracranial epidural haematoma (EDH) is an extremely rare complication following spinal surgery, with only a handful of cases described in the literature. We report the case of a 16-year-old girl who underwent a successful subtotal resection of a giant lumbosacral schwannoma (L2-S2 level). Recovery from general anaesthesia was uneventful; however, her neurological status deteriorated rapidly within 24 h after surgery. A head computed tomography scan revealed a large right frontoparietal EDH with midline shift. An immediate frontotemporoparietal osteoplastic craniotomy and evacuation of the EDH were performed. At 1 year postoperatively, the patient regained full neurological recovery with no radiological signs of growth of the residual tumour. © 2017 S. Karger AG, Basel.

Docosahexaenoic Acid and Neurodevelopmental Outcomes of Term Infants.

Meldrum, Suzanne; Simmer, Karen

Docosahexaenoic acid (DHA), a long-chain polyunsaturated fatty acid, is essential for normal brain development. DHA is found predominantly in seafood, fish oil, breastmilk and supplemented formula. DHA intake in Western countries is often below recommendations. Observational studies have demonstrated an association between DHA intake in pregnancy and neurodevelopment of offspring but cannot fully adjust for confounding factors that influence child development. Randomised clinical trials of DHA supplementation during pregnancy and/or lactation, and of term infants, have not shown a consistent benefit nor harm on neurodevelopment of healthy children born at term. The evidence does not support DHA supplementation of healthy pregnant and lactating women, nor healthy infants. © 2016 S. Karger AG, Basel.

Xeroderma pigmentosum (XP) is a genodermatosis caused by abnormal DNA repair. XP complementation group C (XPC) is the most frequent type in Mediterranean countries. We describe a case with a novel mutation in the XPC gene. A healthy Caucasian male patient was diagnosed with multiple primary melanomas. Digital follow-up and molecular studies were carried out. During digital follow-up 8 more additional melanomas were diagnosed. Molecular studies did not identify mutations in CDKN2A, CDK4 or MITF genes. Two heterozygous mutations in the XPC gene were detected: c.2287delC (p.Leu763Cysfs*4) frameshift and c.2212A>G (p.Thr738Ala) missense mutations. The p.Thr738Ala missense mutation has not been previously described. Missense mutations in the XPC gene may allow partial functionality that could explain this unusual late onset XP. Atypical clinical presentation of XPC could be misdiagnosed when genetic aberrations allow partial DNA repair capacity. © 2015 S. Karger AG, Basel.

Laparoscopic Management of Sclerosing Stromal Tumors of the Ovary Combined with Ectopic Pregnancy.

2015-01-01

Like other stromal-derived gynecological tumors, a sclerosing stromal tumor of the ovary (SSTO) is a rare benign tumor that is difficult to distinguish from a malignant ovarian tumor in clinical practice. An SSTO is routinely treated with laparotomy. Here, we present two extremely rare cases of SSTO with contralateral and ipsilateral tubal pregnancies, in which laparoscopic surgery was performed to remove the tumors. After surgery, one patient (case 1) became pregnant twice within 29 months, and the other patient (case 2) did not become pregnant within 6 months postoperatively. These two cases suggest that laparoscopic management is not only useful in treating SSTO and complicating diseases, but it may also help to reduce unnecessary surgical injury to the ovary. © 2015 S.

Van Epps, Puja; Schmader, Kenneth E; Canaday, David H

2016-01-01

Herpes zoster, clinically referred to as shingles, is an acute, cutaneous viral infection caused by reactivation of the varicella zoster virus, the same virus that causes chickenpox. The incidence of herpes zoster and its complications increase with decline in cell-mediated immunity, including age-associated decline. The most effective management strategy for herpes zoster is prevention of the disease through vaccination in those who are most vulnerable. Despite the demonstrated efficacy in reducing the incidence and severity of herpes zoster, the uptake of vaccine remains low. Here, we will discuss the controversies that surround the live herpes zoster vaccine and address the common clinical questions that arise. We will also discuss the new adjuvanted herpes zoster vaccine currently under investigation. © 2015 S. Karger AG, Basel.

Fluoride Binding to Dental Biofilm Bacteria: Synergistic Effect with Calcium Questioned.

PubMed

2018-06-06

It has been suggested that fluoride binding to dental biofilm is enhanced when more bacterial calcium binding sites are available. However, this was only observed at high calcium and fluoride concentrations (i.e., when CaF2 precipitation may have occurred). We assessed fluoride binding to Streptococcus mutans pellets treated with calcium and fluoride at concentrations allowing CaF2 precipitation or not. Increasing calcium concentration resulted in a linear increase (p < 0.01) in fluoride concentration only in the pellets in which CaF2 precipitated. The results suggest that CaF2 precipitation, rather than bacterially bound fluoride, is responsible for the increase in fluoride binding to dental biofilm with the increase in calcium availability. © 2018 S.

2014-01-01

Acute promyelocytic leukemia (APL) is a rare subtype of AML characterized by a reciprocal balanced translocation between chromosomes 15 and 17 that fuses the PML gene with the RARα gene and leads to the leukemic phenotype. Although best described in large clinical trials of adults, APL, like other forms of AML, also occurs in children. The positive outcome of children with APL mirrors the dramatic increase in survival seen in adults since the introduction of all-trans retinoic acid (ATRA). In this paper, we review the diagnosis of APL in children as well as large, retrospective, clinical trial data collected on pediatric APL. We also raise management issues and toxicities that are unique to children. © 2014 S. Karger AG, Basel.

Non-IgE-Dependent Hypersensitivity to Rocuronium Reversed by Sugammadex: Report of Three Cases and Hypothesis on the Underlying Mechanism.

2016-01-01

We present 3 cases of pseudoallergic (anaphylactoid) reactions to perioperatively administered rocuronium, which rapidly resolved after sugammadex injection. Allergological workup showed no evidence for immediate-type hypersensitivity to the drugs used for anesthesia, including rocuronium. However, rocuronium induced an irritative reaction in skin tests in all 3 patients and in 3 healthy individuals. This reaction was specifically suppressed by adding sugammadex at a 1:1 molecular proportion to rocuronium before the skin tests. This observation suggests that the patients suffered from a pseudoallergic reaction, and indicates that sugammadex might act via the inhibition of non-IgE mediated MRGPRX2 (Mas-related G-protein-coupled receptor member X2)-triggered mast cell degranulation induced by rocuronium. © 2016 S.

2002-01-01

The morphological and functional basis of the excellent clinical outcome of ileal orthotopic neobladders are largely unknown. Only long-term follow-up studies will provide an adequate answer to this unsettled question. We have studied a patient who underwent this type of surgery over 27 years ago. Besides an important secretive adaptation we have found, at the ultrastructural level, that the monolayered epithelium does not show signs of true metaplasia and that changes had occurred in the intercellular junctions, namely that desmosomes are significantly increased. Although limited to a single case, these features, if confirmed by further observations, suggest a working hypothesis for the understanding of the definitive phenotypic adaptation of the ileal epithelium to the new aggressive environment.

Human and canine lymphoid neoplasms are characterized by non-random cytogenetic abnormalities. However, due to the low mitotic activity of the B cells, cytogenetic analyses of B-cell lymphoid proliferations are difficult to perform. In the present study we stimulated canine B-cell lymphoma cells with the immunostimulatory CpG-oligonucleotide DSP30 in combination with interleukin-2 (IL-2) and obtained an adequate number of metaphases. Cytogenetic analyses revealed the loss of one X chromosome as the sole cytogenetic aberration. Chromosome analysis of the corresponding blood showed a normal female karyotype. Monosomy X as the sole clonal chromosomal abnormality is found in human hematopoietic malignancies as well, thus the dog may serve as a promising animal model. Copyright © 2011 S. Karger AG, Basel.

Nocturnal enuresis (NE) is a very common pediatric disorder. The aim of this study was to evaluate the characteristics of patients with NE or urinary incontinence (UI) during a period of 5 years to increase the knowledge on these conditions and optimize their diagnosis and treatment. We enrolled 278 children with NE or UI referred to the pediatric nephrology ambulatory, 'A. Gemelli' University Hospital of Rome, from December 2006 to December 2011. We observed that heredity, parasomnias, left-handedness, polythelia and constipation are correlated to NE and UI. We wanted to clarify the definition of NE and UI and describe our experience on the main characteristics of these conditions by referring to the latest knowledge reported in the literature. 2013 S.

Clinical trials are the cornerstone of evidence-based medicine. By directly comparing different interventions they produce evidence on their relative efficacy and effectiveness This, in turn, can inform secondary research and guideline development to facilitate evidence-based clinical decision making. However, the quality of evidence stemming from clinical trials is frequently poor. Here, the pathway of evidence from basic research to the generation of implementable clinical guidelines will be described. Relevant factors related to trial design and reporting, such as the choice of trial comparators, outcomes and outcome measures, will be described and their influence on evidence synthesis will be discussed. Finally, recommendations on how to improve trials in order to increase their usefulness for evidence generation will be given. © 2018 S. Karger AG, Basel.

Biobank donors and biobank governance face a conceptual challenge akin to clinical patients and their designated surrogate decision-makers, the necessity of making decisions and policies now that must be implemented under future unknown circumstances. We propose that biobanks take advantage of this parallel to learn lessons from the historical trajectory of advance directives and develop models analogous to current 'best practice' advance directives such as Values Histories and TheFive Wishes. We suggest how such models could improve biobanks' engagement both with communities and with individual donors by being more honest about the limits of current disclosure and eliciting information to ensure the protection of donor interests more robustly through time than current 'informed consent' processes in biobanking. © 2014 S.

We report a sibling pair with 46,XX DSD due to an NR5A1 mutation with distinct phenotypes, including external and internal genitalia and gonads, for whom different rearing sexes were selected. Thus, the phenotypes of p.R92W vary, even within a family. The father of the patients showed oligozoospermia with the p.R92W mutation, suggesting that in 46,XY individuals, the mutation would cause various gonadal phenotypes.

Before the 20th century, individuals often did not live beyond the reproductive years, and sexuality of the elderly was not an issue. However, in the current era it is known that as life expectancy improves, both men and women are seeking to preserve their sexuality into old age. While the appreciation of sexuality persists with aging, a decline in sexual activity is typically seen with, and can be attributed to both general health problems as well as specific sexual dysfunctions. Erectile dysfunction is the most frequently diagnosed sexual dysfunction in the older male population. This mini-review provides an overview of contemporary literature concerning epidemiology, pathophysiology, assessment and treatment of erectile dysfunction in the aging male. Copyright © 2011 S.

This paper discusses a number of key challenges facing professionals who work with people who have communication disabilities. The challenges are related to working internationally and in a cross-culturally competent way. Each challenge is discussed, drawing on material from a range of sources, including the papers in the final 2003 edition of FOLIA PHONIATRICA ET LOGOPAEDICA ('International and Cross-Cultural Issues'). The challenges discussed cover how experiences from majority world countries can be used to benefit services elsewhere, 'mainstreaming' commitment to cross-cultural competence, learning from relationships with other professionals, influencing research practice, responding to requests to work internationally and finally, dealing with cultural differences that challenge working practices. Some solutions are suggested and additional questions posed. Copyright 2003 S. Karger AG, Basel

Parenting beliefs and practices of opiate-addicted parents: concealment and taboo.

Hogan, Diane M

2003-07-01

The lifestyle associated with opiate dependence, including drug taking, the buying and selling of drugs, and contact with other drug users, carries potential risks for the safety and well-being of children of drug-using parents. Based on a qualitative interview study conducted with 50 opiate-dependent parents in Dublin, Ireland, the parenting beliefs and practices in relation to children's exposure to drugs and the associated lifestyle are described. Parents saw their lifestyle as potentially risky for their children and their families. The most common strategy adopted by parents was to conceal their drug-related activities and maintain a strict family taboo about these activities. Intervention programmes should be offered to support effective family communication about parental drug dependence. Copyright 2003 S. Karger AG, Basel

Mucosal healing (MH) represents a crucial factor for maintaining gut homeostasis. Indeed, in inflammatory bowel disease, MH has become the standard therapeutical target, because it is associated with more effective disease control, more frequent steroid-free remission, lower rates of hospitalization and surgery, and improved quality of life. In this scenario, gut microbiota is a crucial player in modulating intestinal repair and regeneration process. It can act on the tumor necrosis factor-α production, modulation of reactive oxygen and nitrogen species, activity of matrix metalloproteinases and on many other mechanisms strictly involved in restoring gut health. In this review, we analyze and review the literature on the role of gut microbiota in sustaining mucosal injury and achieving MH. © 2016 S. Karger AG, Basel.

Kindler syndrome is a rare, autosomal-recessive skin disease characterized by bullous poikiloderma. Mucosal manifestations are common that involve the oral cavity, esophagus, urethra and genital organs. A 37-year-old woman with Kindler syndrome received prenatal care at our hospital. Her skin disease did not change during pregnancy and puerperium. Her pregnancy course was uneventful, but an elective cesarean section was performed at 38 weeks of gestation due to vaginal stenosis. Surgical wound healing was uncomplicated. Pregnancy did not exacerbate the cutaneous symptoms of Kindler syndrome in this case. Cesarean delivery may be necessary in cases with severe genital lesions besides obstetrical indications. Careful perioperative management is needed to protect vulnerable skin and mucosa. 2007 S.

As the main protein components of chromatin, histones can alter the structural/functional capabilities of chromatin by undergoing extensive post-translational modifications (PTMs) such as phosphorylation, methylation, acetylation, ubiquitination, sumoylation, and so on. These PTMs are thought to transmit signals from the chromatin to the cell machinery to regulate various processes. Histone phosphorylation is associated with chromosome condensation/segregation, activation of transcription, and DNA damage repair. In this review, we focus on how different histone phosphorylations mark for chromatin change during the cell cycle, the relationship between histone phosphorylation and functional centromeres, and the candidate kinases that trigger and the phosphatase or kinase inhibitors that alter histone phosphorylation. Finally, we review the crosstalk between different PTMs. © 2014 S. Karger AG, Basel.

Molecular targeted therapies for solid tumors: management of side effects.

PubMed

Grünwald, Viktor; Soltau, Jens; Ivanyi, Philipp; Rentschler, Jochen; Reuter, Christoph; Drevs, Joachim

2009-03-01

This review will provide physicians and oncologists with an overview of side effects related to targeted agents that inhibit vascular endothelial growth factor (VEGF), epidermal growth factor (EGF) and mammalian target of rapamycin (mTOR) signaling in the treatment of solid tumors. Such targeted agents can be divided into monoclonal antibodies, tyrosine kinase inhibitors, multitargeted tyrosine kinase inhibitors and serine/threonine kinase inhibitors. Molecular targeted therapies are generally well tolerated, but inhibitory effects on the biological function of the targets in healthy tissue can result in specific treatment-related side effects, particularly with multitargeted agents. We offer some guidance on how to manage adverse events in cancer patients based on the range of options currently available. Copyright 2009 S. Karger AG, Basel.

Commensal-innate immune miscommunication in IBD pathogenesis.

PubMed

Cario, Elke

2012-01-01

Commensal microbiota plays a key role in the health and disease of the host. The innate immune system comprises an essential functional component of the intestinal mucosal barrier, maintaining hyporesponsiveness to omnipresent harmless commensals in the lumen, but rapidly recognizing and combating invading bacteria through diverse antimicrobial mechanisms. Interactions between commensals and innate immune cells are constant, multidimensional and entirely context-dependent. Environment, genetics and host defense differentially modulate commensal-innate immune effects and functions in the intestinal mucosa. In IBD, dysbiosis, mucus layer disruption, impairment in bacterial clearance, intestinal epithelial cell barrier dysfunction and/or immune cell deregulation may lead to commensal-innate immune miscommunication, which critically drives mucosal inflammation and associated cancer.

Fundamental Characteristics of the Newly Developed ATA™ Membrane Dialyzer.

PubMed

Sunohara, Takashi; Masuda, Toshiaki

2017-01-01

Dialysis membranes are often made from synthetic polymers, such as polysulfone. However, membranes made from cellulose triacetate have superior biocompatibility and have been used since the 1980s. On-line hemodiafiltration treatment accompanied by massive fluid replacement is increasingly being used in Europe and Japan, but cellulose triacetate is not suitable for this treatment. Our newly developed asymmetric triacetate membrane, the ATA™ membrane, substantially improved the filtration properties and blood compatibility because of the asymmetric structure and smooth surface of this cellulose acetate membrane. Key Message: The ATA membrane maintains its high permeability even after massive filtration and shows less temporal variation in its permeation performance, lower protein adsorption, and superior biocompatibility compared with conventional membranes. © 2017 S.

Medical treatment of primary biliary cirrhosis and primary sclerosing cholangitis.

PubMed

Holtmeier, J; Leuschner, U

2001-01-01

Treatment of primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) with ursodeoxycholic acid (UDCA) has been in common use since 1985. In PBC, treatment with UDCA improves laboratory data, liver histology, enables a longer transplantation-free interval and prolongs disease survival. Because UDCA is unable to cure the disease newer drugs or combination therapies are still needed. Studies with UDCA and immunosuppressants such as prednisone, budesonide and azathioprine have shown that in selected patients combination therapy may be superior to UDCA monotherapy. PSC is treated successfully with UDCA and endoscopic dilatation of the bile duct strictures. Treatment of extrahepatic manifestations of cholestatic liver disease such as pruritus, fatigue, osteoporosis and steatorrhea can be problematic and time-consuming. Copyright 2001 S.

Holoprosencephaly is a rare congenital malformation resulting from an impaired midline division of the prosencephalon into distinct cerebral hemispheres. Hydrocephalus is a frequent problem among the few survivors with alobar holoprosencephaly (aHPE), its most severe form. The literature about neurosurgical management of hydrocephalus in this condition is limited and dispersed, and there are still some points that need to be resolved. We report the case of a newborn with aHPE, hydrocephalus, and central diabetes insipidus. We delineate the complexity of the management of these patients and emphasize the benefits of using an initial programmable shunt valve. Further discussion about management strategies includes reviewing previous reports and the benefits of shunting for hypothalamic osmoreceptor function. © 2018 S. Karger AG, Basel.

Obesity and heart failure as a mediator of the cerebrorenal interaction.

PubMed

Jindal, Ankur; Whaley-Connell, Adam; Sowers, James R

2013-01-01

The obesity epidemic is contributing substantially to the burden of cardiovascular disease including heart disease and congestive heart failure, in the United States and the rest of the world. Overnutrition as a driver of obesity, promotes alterations in fatty acid, lipid, and glucose metabolism that influence myocardial function and progression of heart failure from diastolic to systolic failure. The association of progressive heart failure and progressive chronic kidney disease is well documented and often referred to as the cardiorenal syndrome, as well as a prognosticator for cerebrovascular disease (e.g. stroke). Whether the relationship between obesity, heart disease/failure and risk for chronic kidney disease and stroke is direct or a confluence of risk factors is poorly understood. Copyright © 2013 S.

Placentophagia or the consumption of the afterbirth is reported in many primate species, whereas cannibalism is a relatively rare event. Based on our field observations over the course of 3 years, we present evidence of placentophagia and mother-infant cannibalism in a free-ranging population of the Taihangshan macaque, Macaca mulatta tcheliensis, in the Mt. Taihangshan area, Jiyuan, Henan, China. We documented 1 case in which a mother consumed the afterbirth of her infant. In a second instance, we observed a fresh placenta discarded on the ground by an unknown individual. We also present a description of the first documented instance of mother-infant cannibalism in the same group of free-ranging rhesus macaques. © 2017 S. Karger AG, Basel.

The neurology of aretaeus: radix pedis neurologia.

Pearce, J M S

2013-01-01

Aretaeus (Aretaios) was a physician born in Cappadocia in about the 2nd century AD, a student of medicine and physician in Alexandria. His works are found in eight books which espoused the physiological and pathological views of the Hippocratic principles derived from the pneumatists and the eclectic schools. Though he has been called the forgotten physician, it has been said that: 'after Hippocrates no single Greek author has equalled Aretaios'. In order to give an indication of his neurological legacy, this paper offers a summary of and quotations from his principal neurological contributions: migraine, vertigo, tetanus, epilepsy, melancholia, strokes and paralysis. One of his most important discoveries was the notion that the pyramidal tract decussates. Copyright © 2013 S. Karger AG, Basel.

Mapping platypus SOX genes; autosomal location of SOX9 excludes it from sex determining role.

2007-01-01

In the absence of an SRY orthologue the platypus sex determining gene is unknown, so genes in the human testis determining pathway are of particular interest as candidates. SOX9 is an attractive choice because SOX9 deletions cause male-to-female sex reversal in humans and mice, and SOX9 duplications cause female-to-male sex reversal. We have localized platypus SOX9, as well as the related SOX10, to platypus chromosomes 15 and 10, respectively, the first assignments to these platypus chromosomes, and the first comparative mapping markers from human chromosomes 17 and 22. The autosomal localization of platypus SOX9 in this study contradicts the hypothesis that SOX9 acts as the sex determining switch in platypus. Copyright 2007 S. Karger AG, Basel.

Existential vulnerability: toward a psychopathology of limit situations.

PubMed

Fuchs, Thomas

2013-01-01

Jaspers' concept of limit situations seems particularly appropriate not only to elucidate outstanding existential situations in general, but also basic preconditions for the occurrence of mental disorders. For this purpose, the concept is first explained in Jaspers' sense and then related to an 'existential vulnerability' of mentally ill persons that makes them experience even inconspicuous events as distressing limit situations. In such situations, an otherwise hidden fundamental condition of existence becomes manifest for them, e.g. the fragility of one's own body, the inevitability of freedom, or the finiteness of life. This fundamental condition is found unbearable and, as a reaction, gives rise to mental illness. This concept of existential vulnerability is illustrated by some psychopathological examples. © 2013 S. Karger AG, Basel.

Malignant nodular hidradenoma (MNH) is a malignant tumor of the eccrine glands, and most commonly involves the head, trunk, and extremities. To the best of our knowledge, MNH of the scrotum has not yet been described in the English literature. Despite the use of surgery, chemotherapy, radiotherapy, and hormonal therapy, optimal treatment of MNH is unclear. We describe the case of a 30-year-old African American man who was diagnosed with locally advanced MNH of the scrotum and treated with surgery. More than 2 years after surgery, the patient is without evidence of disease. This is the first case report of MNH of the scrotum. Surgery alone may be sufficient for the treatment of localized or locally advanced MNH. Copyright © 2010 S. Karger AG, Basel.

On the nature of obsessions and compulsions.

2013-01-01

In this chapter, we give an overview of current and historical conceptions of the nature of obsessions and compulsions. We discuss some open questions pertaining to the primacy of the affective, volitional or affective nature of obsessive-compulsive disorder. Furthermore, we add some phenomenological suggestions of our own. In particular, we point to the patients' need for absolute certainty and the lack of trust underlying this need. Building on insights from Wittgenstein, we argue that the kind of certainty the patients strive for is unattainable in principle via the acquisition of factual knowledge. Moreover, we suggest that the patients' attempts to attain certainty are counter-productive as their excessive conscious control in fact undermines the trust they need. Copyright © 2013 S.

Saffron extracts have a long history of application as skin protectant, possibly due to their ability to scavenge free radicals. In this work, the performance of a hydrogel enriched with antioxidant compounds isolated from saffron crocus (Crocus sativus L.) petals was tested. These hydrogels could be considered as new drug delivery system. Hydrogels are crosslinked polymer networks that absorb large quantities of water but retain the properties of a solid, thus making ideal dressings for sensitive skin. We tested antioxidant-enriched hydrogels on primary mouse fibroblasts. Hydrogels enriched with kaempferol and crocin extracted from saffron petals showed good biocompatibility with in vitro cultured fibroblasts. These new types of hydrogels may find applications in wound treatment and/or beautification. © 2018 S. Karger AG, Basel.

The effects of gated speech on the fluency of speakers who stutter.

PubMed

Howell, Peter

2007-01-01

It is known that the speech of people who stutter improves when the speaker's own vocalization is changed while the participant is speaking. One explanation of these effects is the disruptive rhythm hypothesis (DRH). The DRH maintains that the manipulated sound only needs to disturb timing to affect speech control. The experiment investigated whether speech that was gated on and off (interrupted) affected the speech control of speakers who stutter. Eight children who stutter read a passage when they heard their voice normally and when the speech was gated. Fluency was enhanced (fewer errors were made and time to read a set passage was reduced) when speech was interrupted in this way. The results support the DRH. Copyright 2007 S. Karger AG, Basel.

Stopping bacterial adhesion: a novel approach to treating infections.

Bavington, C; Page, C

2005-01-01

Adhesion and colonization are prerequisites for the establishment of bacterial pathogenesis. The prevention of adhesion is an attractive target for the development of new therapies in the prevention of infection. Bacteria have developed a multiplicity of adhesion mechanisms commonly targeting surface carbohydrate structures, but our ability to rationally design effective antiadhesives is critically affected by the limitations of our knowledge of the human 'glycome' and of the bacterial function in relation to it. The potential for the future development of carbohydrate-based antiadhesives has been demonstrated by a significant number of in vitro and in vivo studies. Such therapies will be particularly relevant for infections of mucosal surfaces where topical application or delivery is possible. (c) 2005 S. Karger AG, Basel

Lung cancer following bronchoscopic lung volume reduction for severe emphysema: a case and its management.

2012-01-01

Bronchoscopic lung volume reduction using endobronchial valves has been suggested as a potentially safer alternative to surgery in selected cases. Complications of this technique include pneumothoraces, pneumonia, COPD exacerbations, hemoptysis, and valve migrations. We report the case of a male patient who developed a parenchymal mass in the treated lobe after valve insertion. Due to severe emphysema, transthoracic needle aspiration was not feasible. Removal of the valves was mandatory to perform transbronchialbiopsies which revealed a non-small cell primary lung cancer. This first description illustrates the potential risk of lung cancer development following bronchoscopic lung volume reduction and highlights the different approach to diagnosis and management of indeterminate peripheral lung lesions needed in this context.

Birth asphyxia can result in sensory impairment, learning and memory deficits without gross brain injury and severe motor deficits. We developed a model of birth asphyxia resulting in mild neurological injury and cognitive impairment using a long-gestation species with precocial fetal development. Spiny mice (Acomys cahirinus) underwent caesarean-section delivery or 7.5 min of asphyxia at 37 days gestational age (term is 39 days). Brain histology was examined at 1 and 7 days of age, and behaviour was evaluated to 28 days of age. Asphyxiated offspring showed significant impairment in non-spatial memory and learning tasks, accompanied by central nervous system inflammation and increased apoptotic cell death but without the presence of large necrotic or cystic lesions.

Greater attention towards genetics as a contributor to group health differences may lead to inappropriate use of race/ethnicity and gender as genetic heuristics and exacerbate health disparities. As part of a web-based survey, 1,035 family physicians (FPs) rated the contribution of genetics and environment to racial/ethnic and gender differences in health outcomes, and the importance of race/ethnicity and gender in their clinical decision-making. FPs attributed racial/ethnic and gender differences in health outcomes equally to environment and genetics. These beliefs were not associated with rated importance of race/ethnicity or gender in clinical decision-making. FPs appreciate the complexity of genetic and environmental influences on health differences by race/ethnicity and gender. Copyright 2008 S. Karger AG, Basel.

Nutrients affecting gastric barrier.

2014-01-01

The gastric barrier could be considered an active tissue involved in many synthetic and metabolic functions, as the immunological defense, by activating mucosal immune system. Barrier integrity results from a balance between protective and aggressive endogenous factors and from their interaction with exogenous factors (steroidal or nonsteroidal anti-inflammatory drugs, dietary nitrates, nitrites and/or NaCl, stress, Helicobacter pylori infection, food allergens and contaminants, metals, chemicals, radiation, smoking and alcohol intake). Nutrients represent the most important exogenous factors affecting gastric barrier because of the impact on people's everyday life. We report evidence from the literature about nutrients affecting gastric barrier and we investigate the possible effect that nutrients can play to determining or maintaining a gastric barrier dysfunction. © 2014 S.

2012-01-01

The optimal treatment for Dandy-Walker malformation is still controversial. Ventriculoperitoneal shunting, cystoperitoneal shunting or combinations are the most common surgical options in the management of this clinical entity. Endoscopic procedures like ventriculocystostomy, 3rd ventriculostomy or endoscopy-assisted shunt surgeries have become the focus of recent publications. We describe a new transcystic endoscopic technique, with the usage of a single ascending transaqueductal shunt catheter with additional holes, whereby both the posterior fossa cyst and supratentorial ventricular compartments are drained effectively. By using this new technique complications associated with combined shunting can be avoided. In addition, by equalizing the pressure within the supra- and infratentorial compartments, the upward or downward herniations associated with single-catheter shunting can be prevented.

Various caries prevention and repair strategies are reviewed in this article ranging from the use of fluoride to nanohydroxyapatite particles. Several of the strategies which combine fluoride and calcium and phosphate treatments have both in vitro and in vivo data showing them to be efficacious if the surface integrity of the lesion is not breached. Once this has occurred, the rationale for cutting off the nutrient supplies to the pathogenic bacteria without the removal of the infected dentine, a noninvasive restorative technique, is discussed using existing clinical studies as examples. Finally two novel noninvasive restorative techniques using fluorohydroxyapatite crystals are described. The need for clinical data in support of emerging caries-preventive and restorative strategies is emphasized. 2015 S. Karger AG, Basel

Infancy and childhood represent a time of unparalleled physical growth and cognitive development. In order for infants and children to reach their linear and neurological growth potential, they must be able to reliably and safely consume sufficient energy and nutrients. Swallowing difficulties (dysphagia) in pediatric populations can have a detrimental effect on dietary intake and, thus, growth and development. As a result, it is imperative to accurately identify and appropriately manage dysphagia in pediatric populations. This article provides an overview of dysphagia in children, as well as common causes of childhood swallowing difficulties, populations at risk for pediatric dysphagia, techniques used to assess swallowing in pediatric patients, and the current treatment options available for infants and children with dysphagia. © 2015 S.

Y-autosome translocations are rare in humans and pigs. In both species, these rearrangements can be responsible for meiotic arrest and subsequent infertility. Chromosome pairing abnormalities on the SSCX, SSCY and SSC1 chromatin domains were identified by analyzing pachytene spermatocytes from a boar carrying a (Y;1) translocation by immunolocalization of specific meiotic protein combined with FISH. Disturbance of the meiotic sex chromosome inactivation (MSCI) was observed by Cot-RNA-FISH and analysis of ZFY gene expression by sequential RNA- and DNA-FISH on spermatocytes. We hypothesized that the meiotic arrest observed in this boar might be due to the silencing of critical autosomal genes and/or the reactivation of some sex chromosome genes. Copyright © 2011 S.

Yeates, Todd O; Jorda, Julien; Bobik, Thomas A

2013-01-01

Bacterial microcompartments are large proteinaceous structures that act as metabolic organelles in many bacterial cells. A shell or capsid, which is composed of a few thousand protein subunits, surrounds a series of sequentially acting enzymes and controls the diffusion of substrates and products into and out of the lumen. The carboxysome and the propanediol utilization microcompartment represent two well-studied systems among seven or more distinct types that can be delineated presently. Recent structural studies have highlighted a number of sophisticated mechanisms that underlie the function of bacterial microcompartment shell proteins. This review updates our understanding of bacterial microcompartment shells, how they are assembled, and how they carry out their functions in molecular transport and enzyme organization.

2014-01-01

Skin naturally changes with age, becoming more fragile. Various stimuli can alter skin integrity. The aim of this study was to evaluate whether sleep deprivation affects the integrity of DNA in skin and exacerbates the effects of aging. Fifteen-month old female Hairless mice underwent 72 h of paradoxical sleep deprivation or 15 days of chronic sleep restriction. Punch biopsies of the skin were taken to evaluate DNA damage by single cell gel (comet) assay. Neither paradoxical sleep deprivation nor sleep restriction increased genetic damage, measured by tail movement and tail intensity values. Taken together, the findings are consistent with the notion that aging overrides the effect of sleep loss on the genetic damage in elderly mice. © 2014 S. Karger AG, Basel.

Thrombosis is characterized by congenital and acquired procatarxis. Nattokinase inhibits thrombus formation in vitro. However, in vivo evaluation of the therapeutic efficacy of nattokinase against thrombosis remains to be conducted. Subcutaneous nattokinase injections of 1 or 2 mg/ml were administered to the tails of rats. Subsequently, κ-carrageenan was intravenously administered to the tails at 12 h after nattokinase injections. The mean length of the infarcted regions in the tails of rats was significantly shorter in rats administered 2 mg/ml of nattokinase than those in control rats. Nattokinase exhibited significant prophylactic antithrombotic effects. Previously, the in vitro efficacy of nattokinase against thrombosis had been reported; now our study has revealed the in vivo efficacy of nattokinase against thrombosis. Copyright © 2010 S.

Piechowski-Jozwiak, Bartlomiej; Bogousslavsky, Julien

2013-01-01

The theme of psychopathy has fascinated artists and the general public for centuries. The first concepts on psychopathy came from the parasciences, such as phrenology where anatomical features were linked to certain psychopathic/immoral behaviors. The concept of psychopathy was recognized by forensic psychiatry a few decades ago and this official recognition was followed by the emergence of scientific and clinical guidelines for the diagnosis and prognosis of psychopaths. These modern tools can also be used for historical purposes by allowing us to look back on fictional works and identify psychopaths in literature. Interpretation of fictitious psychopaths needs to be related to the historical situation in which the novels were written; such investigations can be both enriching and thrilling. Copyright © 2013 S.

Cosentino, Eugenio

Following the results of the PARADIGM-HF trial, the European Society of Cardiology (ESC) guidelines recommend sacubitril/valsartan to replace ACE inhibitors in ambulatory patients with heart failure with reduced ejection fraction (HFrEF) who remain symptomatic despite optimal therapy and who fit trial criteria. However, the optimal use of sacubitril/valsartan in clinical practice needs further investigation. We report here the cases of 2 patients with HFrEH successfully treated with sacubitril/valsartan in our daily practice. Both subjects presented multiple comorbidities and received an implantable cardioverter defibrillator in primary prevention. In both patients, therapy with sacubitril/valsartan led to prompt (30 days) amelioration of heart function, with a corresponding decrease in NHYA class and without any relevant safety issue. © 2017 S.

Oxytetracycline is a broad-spectrum antibiotic, but its nonantibacterial effects in the human respiratory tract are unknown. In this study, the effects of oxytetracycline on mucus secretion and inflammation were examined by PCR and ELISA in the human airway epithelial cell line NCI-H292. Oxytetracycline (10 μg/mL) significantly inhibited TNF-α-induced MUC5AC gene expression and MUC5AC protein levels in NCI-H292 cells. It also downregulated IL-8 and IL-1β gene expression and IL-1β protein levels. Our findings demonstrated that oxytetracycline suppressed mucus production and inflammation in human respiratory epithelial cells, providing further evidence for the usefulness of oxytetracycline for human airway inflammatory diseases. © 2017 S.

A laryngographic and laryngoscopic study of tone production in Northern Vietnamese, a language whose tones combine both fundamental frequency (f0) modulations and voice qualities (phonation types), was conducted with 5 male and 5 female speakers. Results show that the f0 contours of Northern Vietnamese tones are not only attributable to changes in vocal fold length and tension (partly through changes in larynx height), but that f0 drops are also largely caused by the glottal configurations responsible for the contrastive voice qualities associated with some of the tones. We also find that voice quality contrasts are mostly due to glottal constriction: they occasionally involve additional ventricular fold incursion and epiglottal constriction, but these articulations are usually absent.

It has been described that many Charcot-Marie-Tooth syndrome type 2 patients are affected by a very disabling type of tremor syndrome, the pathophysiology of which remains unclear. Deep brain stimulation (DBS) has been successfully applied to treat most types of tremors by implanting electrodes in the ventral intermediate nucleus of the thalamus (Vim). We used DBS applied to the Vim in 2 patients with severe axonal inherited polyneuropathies who developed a disabling tremor. Both patients responded positively to stimulation, with a marked reduction of the tremor and with an improvement of their quality of life. We report 2 cases of tremor associated with a hereditary neuropathy with a good response to DBS. © 2017 S. Karger AG, Basel.

Recent developments in research methods and techniques, such as whole-exome and -genome sequencing, have substantially improved our understanding of genetic conditions. Special progress has been made in the field of genotrichoses, or hereditary hair diseases, a field that has been obscure for many years. The underlying genes for many of the monogenic hair diseases are now known. Additionally, complex analyses of large cohorts of patients have given us the first clues to the genes associated with polygenic hair disorders, such as androgenetic alopecia and alopecia areata. Thanks to these major findings, the sophisticated regulation of the morphogenesis, development and growth of hair follicles has begun to be revealed, and new players in this delicate molecular interplay have been exposed. © 2015 S.

The identification of mechanisms necessary for memory consolidation and reconsolidation, the processes by which the posttraining and postretrieval fragile memory traces become stronger and insensitive to disruption, has indicated new approaches for investigating and treating psychopathologies. In this review, we will discuss some key biological mechanisms found to be critical for memory consolidation and strengthening, the role/s and mechanisms of memory reconsolidation, and how the interference with consolidation and/or reconsolidation can modulate the retention and/or storage of memories that are linked to psychopathologies. © 2014 S.

This study examines whether social inequality in tooth brushing frequency among adolescents changed from 1991 to 2014. The data material was seven comparable cross-sectional studies of nationally representative samples of 11- to 15-year-olds in Denmark with data about frequency of tooth brushing and occupation of parents. The total number of participants was 31,464, of whom 21.7% brushed their teeth less than the recommended 2 times a day. The absolute social inequality measured as prevalence difference between low and high social class increased from 7.7% in 1991 to 14.6% in 2014. The relative social inequality assessed by odds ratios for infrequent tooth brushing also increased from 1991 to 2014. © 2015 S. Karger AG, Basel.

Vertebral Artery Dissection in a Bouncy Castle Injury: Case Report and Literature Review.

PubMed

Ripa, Valeria; Urakov, Timur M; Jernigan, Sarah C

2017-01-01

There is an increased rate of injuries associated with activities on bouncy castles. The purpose of this article was to describe the case of a 6-year-old boy who sustained a brain infarct as a consequence of a left posterior inferior cerebellar artery dissection due to improper landing in a bouncy castle and who required a suboccipital craniotomy. The second goal was to outline the literature review regarding cervical trauma related to trampoline or bouncy castle accidents in pediatric populations. Based on the described case and reviewed studies, bouncy castle or any other activity resulting in hyperflexion or hyperextension of the neck should be carefully evaluated for cervical spine fractures and vascular injuries. © 2017 S.

Use of the International Pharmaceutical Federation's Basel Statements to Assess and Advance Hospital Pharmacy Practice: A Scoping Review.

PubMed

Penm, Jonathan; Chaar, Betty; Moles, Rebekah J

2016-01-01

The Basel statements of the International Pharmaceutical Federation, which provide the first global, unified vision for the hospital pharmacy profession, have recently been revised. Originally released in 2008, the Basel statements have since been made available in 21 languages, and thus have the potential for great impact around the world. To conduct a scoping review to examine the extent and nature of research activity related to the Basel statements. Google Scholar, PubMed, and International Pharmaceutical Abstracts were searched using the key term "Basel statements" for relevant research articles. From each included study, data were extracted on geographic location, study design, study outcomes, and use of the Basel statements. The search strategy generated 113 results. Further refinement resulted in 14 English-language articles that met the inclusion criteria. Four of these articles focused on adapting the Basel statements to European practice, an initiative of the European Association of Hospital Pharmacists that led to development of the European statements of Hospital Pharmacy. Six studies focused on monitoring hospital pharmacy practice in Uganda, the Pacific island countries, and the Western Pacific Region. These studies provide valuable baseline data to measure and track the development of hospital pharmacy practices in their respective countries and regions. The remaining 4 studies used qualitative methods to explore the barriers to and facilitators of implementation of the Basel statements in South Africa, China, and Australia. The Basel statements have led to multiple initiatives around the world, involving more than 70 countries. The European and Western Pacific regions have been the most active. Current initiatives should be continued to ensure identification and resolution of issues related to sustaining their use over time.

Awareness of memory failures and motivation for cognitive training in mild cognitive impairment.

PubMed

Werheid, Katja; Ziegler, Matthias; Klapper, Annina; Kühl, Klaus-Peter

2010-01-01

Awareness of cognitive deficits is considered to be decisive for the effectiveness of cognitive training in mild cognitive impairment (MCI). However, it is unclear in what way awareness influences motivation to participate in cognitive training. Thirty-two elderly adults with MCI and 72 controls completed the 5-scale Memory Functioning Questionnaire (MFQ) and a motivation questionnaire. The predictive value of the MFQ scales on motivation was analyzed using regression analysis. In the MCI group, but not in controls, higher perceived frequency of memory failures was associated with a lower motivation score. Our findings indicate that, in MCI, greater awareness of cognitive deficits does not necessarily increase motivation to participate in cognitive trainings, and suggest that success expectancy may be a moderating factor.

Kiefer, J; Weber, A; Pfennigdorff, T; von Ilberg, C

2000-01-01

Insertion of a sufficient number of electrodes is important for a successful use of cochlear implants. We investigated the results of scala vestibuli insertion for cochlear implantation in cases of obstructed scala tympani. In a series of 200 cochlear implantations, scala vestibuli insertion was successfully performed in 4 cases with obstruction of the scala tympani. Etiologies included a temporal bone fracture, severe otosclerosis and malformations of the cochlea. The maximum insertion depth obtained via the scala vestibuli was 30 mm. Postoperative results were comparable to patients in whom conventional scala tympani insertion was performed. No adverse effects related to the site of insertion were observed. Scala vestibuli insertion offers a valuable alternative in cases of obstructed scala tympani that can be employed for a variety of etiologies. Copyright 2000 S. Karger AG, Basel

Paracrine regulation of matrix metalloproteinase expression in the normal human endometrium.

PubMed

Osteen, K G; Keller, N R; Feltus, F A; Melner, M H

1999-01-01

Endometrial expression of matrix metalloproteinase (MMP)-3, MMP-7 and MMP-11 occurs during menstrual breakdown and subsequent estrogen-mediated growth, but not during the secretory phase. These enzymes are suppressed by progesterone treatment. Paracrine factors, including transforming growth factor-beta (TGF-beta) and retinoic acid, are also critical for MMP regulation in the endometrium. In contrast, inflammatory cytokines such as interleukin-1alpha may block or interfere with steroid-mediated MMP regulation at ectopic sites of growth. Using in vitro models, our laboratory has investigated the complex interactions between progesterone and locally produced cytokines that may affect MMP expression during the development of endometriosis. Our results indicate that targeting the regulation of MMPs may represent an appropriate therapeutic strategy for the treatment of endometriosis. Copyrightz1999S. KargerAG,Basel

Monogenic Disorders of Adrenal Steroidogenesis.

PubMed

Baranowski, Elizabeth S; Arlt, Wiebke; Idkowiak, Jan

2018-06-06

Disorders of adrenal steroidogenesis comprise autosomal recessive conditions affecting steroidogenic enzymes of the adrenal cortex. Those are located within the 3 major branches of the steroidogenic machinery involved in the production of mineralocorticoids, glucocorticoids, and androgens. This mini review describes the principles of adrenal steroidogenesis, including the newly appreciated 11-oxygenated androgen pathway. This is followed by a description of pathophysiology, biochemistry, and clinical implications of steroidogenic disorders, including mutations affecting cholesterol import and steroid synthesis, the latter comprising both mutations affecting steroidogenic enzymes and co-factors required for efficient catalysis. A good understanding of adrenal steroidogenic pathways and their regulation is crucial as the basis for sound management of these disorders, which in the majority present in early childhood. © 2018 The Author(s) Published by S.

Carriers of completely balanced chromosomal translocations have all necessary genetic information. Nevertheless, because of the possibility of maldistribution during gametogenesis, they are at increased risk for infertility, miscarriage, stillbirth or having a child with congenital anomalies including mental retardation. As postnatal clinical reports are infrequent, prediction of clinical course for specific unbalanced karyotypes diagnosed during pregnancy remains difficult. Here, we report the 6th case of partial trisomy 6p and partial monosomy 20p due to an unbalanced adjacent-1 segregation of the rare familial translocation t(6;20)(p21;p13). We give a thorough clinical description of the present case, demonstrating broad phenotypic overlap with the 5 previously published cases reviewed here, providing important data on postnatal outcome.

2018-06-19

The advanced snakes (Caenophidia), the important amniote lineage encompassing more than 3,000 living species, possess highly conserved female heterogamety across all families. However, we still lack any knowledge on the gene(s) and the molecular mechanism controlling sex determination. Triploid individuals spontaneously appear in populations of diploid species and can provide an important insight into the evolution of sex determination. Here, we report a case of spontaneous triploidy in a male of the twin-spotted ratsnake (Elaphe bimaculata) with ZZW sex chromosomes. We speculate that as both ZZ and ZZW individuals develop male gonads, the ratio between the number of Z chromosomes and autosomes, and not the presence of the W chromosome in the genome, drives sex determination in the advanced snakes. © 2018 S.

Stem Cell Models: A Guide to Understand and Mitigate Aging?

PubMed

Brunauer, Regina; Alavez, Silvestre; Kennedy, Brian K

2017-01-01

Aging is studied either on a systemic level using life span and health span of animal models, or on the cellular level using replicative life span of yeast or mammalian cells. While useful in identifying general and conserved pathways of aging, both approaches provide only limited information about cell-type specific causes and mechanisms of aging. Stem cells are the regenerative units of multicellular life, and stem cell aging might be a major cause for organismal aging. Using the examples of hematopoietic stem cell aging and human pluripotent stem cell models, we propose that stem cell models of aging are valuable for studying tissue-specific causes and mechanisms of aging and can provide unique insights into the mammalian aging process that may be inaccessible in simple model organisms. © 2016 S.

Jarcho-Levin syndrome (JLS; spondylothoracic dysplasia) is a congenital disease characterized by multiple vertebral and rib malformations, causing a short trunk dwarfism commonly leading to respiratory insufficiency and death during the first years of life. We describe a case diagnosed during the second trimester routine ultrasound scan for screening of fetal anomalies without a previous family history. The fetus had a severe disorganization of the spine and ribs, skeletal kyphosis, with several hemivertebrae and a small thorax. All of the findings at postmortem examination confirmed the ultrasound features and were consistent with the JLS. To the best of our knowledge there is only one case reported in the literature of a prenatal diagnosis of the syndrome in a family with low risk for the condition. Copyright (c) 2005 S.

James, Jack E; Gregg, M Elizabeth; Kane, Marian; Harte, Frances

2005-01-01

This study aimed to determine whether sustained (i.e. dietary) use of caffeine has net effects on performance and mood compared with sustained abstinence, and whether dietary caffeine restores performance and mood adversely affected by sleep restriction. Participants (n = 96) alternated weekly between ingesting placebo and caffeine (1.75 mg/kg) three times daily for 4 consecutive weeks, while either rested or sleep restricted. Performance involved either a single task requiring sustained vigilance or a varied battery of brief psychomotor and cognitive tasks, and mood was assessed using the Profile of Mood States. Caffeine had no significant net enhancing effects for either performance or mood when participants were rested, and produced no net restorative effects when performance and mood were degraded by sleep restriction.

We compared outcome and complications of three simple varicocelectomy techniques. Groups were divided according to whether they would receive the Ivanissevich technique (n = 55), Tauber's technique (n = 51) or subinguinal sclerotherapy (n = 49). Selection criteria were: infertility >1 year, subnormal semen, sonographic diameter of veins >3 mm and time of regurge >2 s. Patients were randomly assigned to the groups of treatment, with follow-up every 3 months for 1 year. Improvement was only in sperm count and total motility for all groups. Pregnancy rates were 20, 13.73 and 12.24%, respectively, with no significant difference between groups. Hydrocele occurred only in the group which received the Ivanissevich technique (5.5%). Tauber's technique is simple; however, it has the disadvantage of multiple branching of small veins. Copyright © 2010 S. Karger AG, Basel.

Nitrogen metabolism and nitrogen control in corynebacteria: variations of a common theme.

Walter, Britta; Hänssler, Eva; Kalinowski, Jörn; Burkovski, Andreas

2007-01-01

The published genome sequences of Corynebacterium diphtheriae, Corynebacterium efficiens, Corynebacterium glutamicum and Corynebacterium jeikeium were screened for genes encoding central components of nitrogen source uptake, nitrogen assimilation and nitrogen control systems. Interestingly, the soil-living species C. efficiens and C. glutamicum exhibit a broader spectrum of genes for nitrogen transport and metabolism than the pathogenic species C. diphtheriae and C. jeikeium. The latter are characterized by gene decay and loss of functions like urea metabolism and nitrogen-dependent transcription control. The global regulator of nitrogen regulation AmtR and its DNA-binding motif are conserved in C. diphtheriae, C. efficiens and C. glutamicum, while in C. jeikeium, an AmtR-encoding gene as well as putative AmtR-binding motifs are missing.

Fernández, Constanza E; Fontana, Margherita; Samarian, Derek; Cury, Jaime A; Rickard, Alexander H; González-Cabezas, Carlos

This study aimed to explore the effect of fluoridated toothpastes on biofilm architecture and enamel demineralization in an in vitro biofilm model. Streptococcus mutans was grown on enamel and treated with slurries of commercial toothpastes, containing SnF2 or NaF. Water and chlorhexidine were used as negative and positive controls, respectively. The developed biofilms were imaged and enamel demineralization was measured. SnF2 and NaF toothpaste treatments significantly reduced enamel demineralization, but SnF2 toothpaste was more effective. Only SnF2 toothpaste and chlorhexidine treatments caused reductions on biofilm mass and thickness. In conclusion, this biofilm model was able to differentiate the effects of the SnF2 and NaF toothpastes on biofilm architecture and enamel demineralization. © 2016 S. Karger AG, Basel.

Models to evaluate the anticaries potential of fluoride (F) formulations containing monofluorophosphate (MFP) should consider the release of F ion to the oral environment by its enzymatic hydrolysis. This was tested in situ, using a test plaque of a strain of Streptococcus mutans which presents high MFPase activity at pH 5.0. The test plaque was exposed to non-F or MFP (1,450 microg F/g) dentifrices and the fluid phase of the plaque was analyzed after 15, 30, 45 and 75 min. MFP concentration in the plaque fluid decreased over time after exposure to MFP dentifrice, but F ion reached 134.9 +/- 32.0 microM at 15 min and decreased significantly only at 75 min, suggesting continuous MFP hydrolysis by the test plaque.

To analyze the aggregate impact factor (AIF) in ophthalmology, its inflation rate, and its relation to other subject fields. A retrospective, database review of all subject fields in the Journal Citation Reports (JCR), Science edition. Citation data, AIF, number of journals and citations from the years 2003-2011 were analyzed. Data were retrieved from JCR. Future trends were calculated using a linear regression method. The AIF varies considerably between subjects. It shows also an inflation rate, which varies annually. The AIF inflation rate in ophthalmology was not as high as the background AIF inflation rate. The AIF inflation rate caused the AIF to increase annually. Not considering these variations in the AIF between years and between fields will make the AIF as a bibliometric tool inappropriate.

Focal Dystonia in Hemiplegic Upper Limb: Favorable Effect of Cervical Microsurgical DREZotomy Involving the Ventral Horn - A Report of 3 Patients.

PubMed

Sindou, Marc; Georgoulis, George

2016-01-01

Focal dystonia in hemiplegic upper limbs is poorly responsive to medications or classical neurosurgical treatments. Only repeated botulinum toxin injections show efficacy, but in most severe cases effects are transient. Cervical DREZ lesioning, which has proven efficacious in hyperspasticity when done deeply (3-5 mm) in the dorsal horn, may have favorable effects on the dystonic component when performed down to, and including, the base of the ventral horn (5-6 mm in depth). Three patients underwent deep cervical microsurgical DREZotomy (MDT) for focal dystonia in the upper limb. Hypertonia was reduced, and sustained dystonic postures were suppressed. Residual motor function (hidden behind hypertonia) came to the surface. Cervical MDT may be a useful armamentarium for treating refractory focal dystonia in the upper limb. © 2016 S.

"Sleep Medicine" is now a specialty in its own right. Currently, there is increasing recognition of the very negative impact sleep disorders have on learning, education, safety, and quality of life. Technological advances will help us to break down diagnoses (e.g., narcolepsy has now been subdivided into types 1 and 2, depending upon the hypocretin levels in the spinal fluid) and to discover relationships to other bodily systems (e.g., type 1 narcolepsy potentially being an autoimmune disorder). The modern lifestyle of many, as characterized by a shortening of sleep periods, shift work, jet lag, and the need to be constantly available, means that advances in sleep medicine may result in a major understanding of more balanced "work-rest lifestyle" modifications. © 2017 S.

Parapharyngeal space tumors are known for having a difficult approach, misleading diagnosis and for representing a treatment challenge. Hemangiopericytomas account for less than 1% of all vascular neoplasms and 3% of all soft tissue sarcomas. Only 14 cases have been reported in the worldwide literature in this location. We present a case of a 44-year-old male who was referred for evaluation. A CT scan and MRI showed a large parapharyngeal mass of a possible salivary gland origin. The patient underwent a lateral cervicotomy associated with a transparotid-transmandibular approach, obtaining a vimentin-positive immunostaining tumor defining the diagnosis. The accurate management and prognosis of this type of neoplasm are provided by the definite diagnosis obtained by a correct histopathologic assessment. A high clinical suspicion is essential. © 2014 S. Karger AG, Basel.

Epigenetic Alterations in Cellular Immunity: New Insights into Autoimmune Diseases.

PubMed

Wang, Zijun; Lu, Qianjin; Wang, Zhihui

2017-01-01

Epigenetic modification is an additional regulator in immune responses as the genome-wide profiling somehow fails to explain the sophisticated mechanisms in autoimmune diseases. The effect of epigenetic modifications on adaptive immunity derives from their regulations to induce a permissive or negative gene expression. Epigenetic events, such as DNA methylation, histone modifications and microRNAs (miRNAs) are often found in T cell activation, differentiation and commitment which are the major parts in cellular immunity. Recognizing the complexity of interactions between epigenetic mechanisms and immune disturbance in autoimmune diseases is essential for the exploration of efficient therapeutic targets. In this review, we summarize a list of studies that indicate the significance of dysregulated epigenetic modifications in autoimmune diseases while focusing on T cell immunity. © 2017 The Author(s)Published by S.

2014-01-01

Immune activation and inflammation, likely triggered by amyloid-beta (Aβ) deposition, play a remarkable role in the pathogenesis of Alzheimer's disease (AD), which is the most frequent cause of dementia in the elderly. The principal cellular elements of the brain innate immune system likely to be involved in such processes are microglia. In an attempt to search for new disease-modifying drugs, the immune system has been addressed, with the aim of removing deposition of Aβ or tau by developing vaccines and humanized monoclonal antibodies. The aim of this review is to summarize the current evidence regarding the role played by microglia and inflammatory molecules in the pathogenesis of AD. In addition, we will discuss the main active and passive immunotherapeutic approaches. © 2014 S. Karger AG, Basel.

Leveraging Big Data and Electronic Health Records to Enhance Novel Approaches to Acute Kidney Injury Research and Care.

Sutherland, Scott M; Goldstein, Stuart L; Bagshaw, Sean M

2017-01-01

While acute kidney injury (AKI) has been poorly defined historically, a decade of effort has culminated in a standardized, consensus definition. In parallel, electronic health records (EHRs) have been adopted with greater regularity, clinical informatics approaches have been refined, and the field of EHR-enabled care improvement and research has burgeoned. Although both fields have matured in isolation, uniting the 2 has the capacity to redefine AKI-related care and research. This article describes how the application of a consistent AKI definition to the EHR dataset can accurately and rapidly diagnose and identify AKI events. Furthermore, this electronic, automated diagnostic strategy creates the opportunity to develop predictive approaches, optimize AKI alerts, and trace AKI events across institutions, care platforms, and administrative datasets. © 2017 S.

Subcutaneous pyelovesical bypass graft (SPBG) is a urinary diversion treatment option for ureteral obstruction. Initially its use was limited to palliative care patients. However, the indication profile has been extended to selected patients with benign conditions causing ureteral obstruction and hydronephrosis. Occlusion of SPBGs is rarely reported and mostly related to infections. We describe the clinical case of a patient with SPBG after iatrogenic ureteral stricture who was not suitable for other reconstructive treatment forms due to distinct retroperitoneal scarring after multiple previous surgeries. Several months after the SPBG insertion, the patient developed complete occlusion of the system with uric acid stone material. Sufficient endoscopic intervention was not feasible. After forced chemolitholysis, the stone mass could be completely dissolved. Since then the patient has remained symptom-free. © 2014 S. Karger AG, Basel.

Role of dietary immunomodulatory factors in the development of immune tolerance.

PubMed

Prescott, Susan L

2009-01-01

The development of oral tolerance occurs during critical early stages of immune development. Rising rates of food allergy and other immune-mediated food reactions are an indication that oral tolerance is highly susceptible to environmental change. There is growing evidence that this many not be due food allergens per se, but rather to changing exposure to other key immunomodulatory exposures in this critical period. Successful tolerance appears to depend on many concurrent environmental influences during the period of first allergen encounter, including favorable gut colonization, and the presence of key immunomodulatory factors in breast milk and the infant diet. This review explores the potential effects of early dietary and nutritional factors in tolerogenic immune processes that are normally initiated during initial food allergen encounter.

This report describes a male patient with temporal lobe epilepsy who developed a persistent paranoid-hallucinatory state at the age of 23. The essential feature of his delusion was that he had repeatedly lived part of his life, namely between the ages of 21 and 25 years. The patient repeatedly attempted suicide to escape the endless repetition. His paramnesia has some similarity with a déjà vu phenomenon, which is a common ictal manifestation of temporal lobe epilepsy. However, while only a sense of vague familiarity is evoked in a déjà vu phenomenon, conscious recollection is experienced during his paramnesia. We attempted to explain the pathophysiological mechanism of the patient's paramnesia in the framework of the current neurobiological theory of human memory. Copyright 2003 S. Karger AG, Basel

In order to ensure safe magnetic resonance-guided, high-intensity focused, ultrasound ablation of uterine leiomyomas, the ultrasound beam path should be free of intervening scar and bowel. Pre-treatment MRI of a 9-cm long and 7.7-cm wide leiomyomatous uterus in a 39-year-old woman with menorrhagia and abdominopelvic pain initially demonstrated a focused ultrasound treatment path without a bowel between the uterus and the abdominal wall. On the day of ablation, however, multiple loops of bowel were observed in the ultrasound beam path by MRI. Uterine repositioning was accomplished with a 76-mm donut vaginal pessary, which anteverted the fundus and successfully displaced the bowel. A vaginal pessary may aid in repositioning an axial or retroverted uterus to enable ablation of uterine leiomyomas. © 2015 S. Karger AG, Basel.

2017-01-01

The prognosis of head and neck squamous cell carcinoma (HNSCC) is largely based on disease stage. Despite improvements in treatment, recurrence rates are still considered high. Currently, disease progression or regression after curative treatment is monitored by clinical evaluation combined with flexible endoscopy and/or imaging. However, specificity of imaging is low due to the posttreatment effects. Detection of circulating tumor DNA (ctDNA) from blood samples of HNSCC patients is a minimally invasive technique that could lead to an earlier detection of recurrence. In addition, digital droplet PCR (ddPCR) could be used to sensitively detect these mutational targets. Future study on ctDNA using ddPCR in blood samples of HNSCC patients is recommended during the follow-up stage to detect recurrences in a timely manner. © 2016 S. Karger AG, Basel.

2003-11-01

A forskolin derivative, colforsin daropate hydrochloride (CDH), has been introduced as an inotropic agent that acts directly on adenylate cyclase to increase intracellular cyclic AMP (cAMP) levels and ventricular contractility, resulting in positive inotropic activity. We investigated the effects of CDH on rat mesangial cell (MC) proliferation. CDH (10(-7)-10(-5) mol/l) inhibited [(3)H]thymidine incorporation into cultured rat MCs in a concentration-dependent manner. CDH (10(-7)-10(-5) mol/l) also decreased cell numbers in a similar manner, and stimulated cAMP accumulation in MCs in a concentration-dependent manner. A protein kinase A inhibitor, H-89, abolished the inhibitory effects of CDH on MC mitogenesis. These findings suggest that CDH would inhibit the proliferation of rat MCs via the cAMP pathway.

Cross-sectional study using 952 cases of the Registry of Dementias of Girona. A binary logistic regression was used to detect variables associated with the use of CNS drugs depending on the time to diagnosis. CNS drugs were consumed by 95.8% of the AD patients. Only antipsychotics presented a statistically significant increase in the frequency of prescription to patients with longer time elapsed from symptom onset to AD diagnosis. Longer time elapsed from the onset of symptoms to the diagnosis resulted in increased probability of antipsychotic consumption. Copyright © 2012 S. Karger AG, Basel.

The physiology of deglutition and the pathophysiology and complications of oropharyngeal dysphagia.

Steele, Catriona M

2012-01-01

The opening session of the 2nd International Conference on Oropharyngeal Dysphagia featured a series of invited talks reviewing the definition of dysphagia, its prevalence and its pathophysiology. The discussion arising from these talks focused heavily on the current underrecognition of dysphagia as a significant concern for older adults, particularly those over 75. The burdens associated with dysphagia in this sector of the population were recognized to be substantial, both in social/psychological terms and in terms of economic consequences for the healthcare system. The importance of developing swallow screening protocols as a routine method for the early identification of dysphagia and aspiration was explored. The idea of launching political initiatives aimed at increasing awareness and the utilization of appropriate dysphagia healthcare codes was also discussed. Copyright © 2012 S. Karger AG, Basel.

Subicular degeneration occurs in amyotrophic lateral sclerosis (ALS) patients. However, it was unknown whether microscopic subicular degeneration could be observed as macroscopic changes and whether these changes were associated with the transactive-response DNA binding protein 43 kDa (TDP-43) pathology. Topographic differences between subicular degeneration caused by ALS and Alzheimer disease (AD) had also not been characterized. Here we investigated the subiculum and related areas in autopsied brains from 3 ALS and 3 AD patients. Macroscopic subicular thinning and corresponding astrocytosis were pronounced in ALS compared to AD. This thinning was frequently accompanied by TDP-43 pathology in the transentorhinal cortex and nucleus accumbens. The preferential susceptibility of the perforant pathway to TDP-43 deposition may be an underlying cause of subicular thinning in ALS. © 2018 S. Karger AG, Basel.

New insight on the response of bacteria to fluoride.

PubMed

Breaker, R R

2012-01-01

Fluoride has been used for decades to prevent caries and it is well established that this anion can inhibit the growth of bacteria. However, the precise effects that fluoride has on bacteria and the mechanisms that bacteria use to overcome fluoride toxicity have largely remained unexplored. Recently, my laboratory reported the discovery of biological systems that bacteria use to sense fluoride and reduce fluoride toxicity. These sensors and their associated genes are very widespread in biology, which has implications for a number of issues that are central to the use of fluoride for dental care. Below I provide a summary of our findings, comment on some of the key prospects for expanding our understanding of fluoride's effects on biology, and propose some future uses of this knowledge.

Pioneering the concepts of stereognosis and polyradiculoneuritis: Octave Landry (1826-1865).

PubMed

Walusinski, Olivier

2013-01-01

Octave Landry was one of a long list of fine 19th century clinicians who died very young and whose discoveries in physiology and descriptions of new clinical pictures helped found current-day neurology. In 1852, Landry proposed a new take on the physiology of sensation which laid the ground for the concepts of proprioception and stereognosis. He also described the clinical picture of a rapidly progressing ascending paralysis, which in 1859 prefigured Guillain-Barré syndrome. In discussing his very active life, we will mention the hydrotherapies in fashion at the time and the pleasures of Parisian society. Landry's career was also marked by terrible cholera epidemics, one of which killed him at age 39, in the prime of his working life as a devoted physician. Copyright © 2013 S. Karger AG, Basel.

Genistein and daidzein stimulate hyaluronic acid production in transformed human keratinocyte culture and hairless mouse skin.

PubMed

Miyazaki, Kouji; Hanamizu, Tomoko; Iizuka, Ryoko; Chiba, Katsuyoshi

2002-01-01

We examined the effects of the soy isoflavones genistein (Gen) and daidzein (Dai) on the production of hyaluronic acid (HA) in a transformed human keratinocyte culture and in hairless mouse skin following topical application for 2 weeks. Gen and Dai, but not the glycosides thereof, significantly enhanced the production of HA in vitro and in vivo. Histochemistry using an HA-binding protein revealed that topical Gen and estradiol raised both the density and intensity of HA staining, which was abundant in the murine dermis. It is suggested that Gen and Dai are not released from their respective glycosides in culture or murine skin. Moreover, topical Gen and Dai may prevent and improve the cutaneous alterations caused by the loss of HA in skin. Copyright 2002 S. Karger AG, Basel

Duplex scanning diagnosis of internal carotid artery dissections. A case control study.

2007-01-01

The reliability of duplex scanning (DS) for the diagnosis of internal carotid artery dissections (ICAD) is not clear. Nine DS signs known to be suggestive for the diagnosis of ICAD were compared between 70 patients with ICAD and 70 matched patients without dissection. Visible internal tapering occlusion, regular eccentric narrowing channel, ectasia beyond the carotid bulb, resistive index asymmetry, blood flow slowdown, ophthalmic artery blood flow inversion, and biphasic flow are more frequent in cases than in controls (p < 0.001). Atheroma plaques were absent in 80% of ICAD. When DS direct signs and hemodynamic signs were studied, sensitivity was 90% and specificity 60%. Diagnosis of ICAD by DS could be improved if direct signs were combined with hemodynamic signs, giving a high sensitivity and a rather good specificity. Copyright 2007 S. Karger AG, Basel.

In humans, the gut microbiota forms a complex ecosystem consisting of a vast number of bacteria, Archaea, fungi and viruses. It represents a major stimulus to the development of the immune system and many other physiological functions, so that it may shape the individual's susceptibility to infectious and immune-mediated diseases. The emergence of new '-omics' methods recently revolutionized the way we study the host-microbe interactions, but they also raised new questions and issues. In this review, we discuss the impact of these new data on the current and future therapies for chronic inflammatory diseases. We also outline the major conceptual, technical and interpretational issues that recently led to some misleading conclusions and discuss in brief the current research directions in the field. © 2017 S.

Apter, Dan; Molina Cartes, Ramiro

2012-01-01

All children and young people have the right to age-appropriate sexuality education regardless of gender, sexual orientation, ability or faith. Sexuality education provides knowledge, skills and positive values to determine and enjoy their sexuality, have safe, fulfilling relationships if one so wishes and decides, and to take responsibility for their own and for a possible partner's sexual health and well-being. Several international programs have been developed and recently published by the Population Council, IPPF and other coworkers, by UNICEF, and by WHO Europe. This chapter will briefly describe recent global development in sexuality education, and then, as examples, experience from two countries, Finland and Chile. The experiences from these school based programs suggest an important role of sexuality education. Copyright © 2012 S. Karger AG, Basel.

Therapeutic options for Ebola virus disease (EVD) are currently limited to (1) best supportive care, and (2) evolving virus-specific therapies, resulting from decades of analyzing one of the world's deadliest diseases. Supportive care ranges from oral or intravenous rehydration therapy and anti-emetics in developing countries to much more extensive life-support interventions in resource-rich countries. Current EVD-specific therapies attempt to either interfere with the earliest steps of viral replication or to elicit a strong immune response against the virus. An entirely new approach is the extracorporeal elimination of viruses and viral glycoproteins by lectin affinity plasmapheresis. Herein, we report for the first time the successful and safe use of lectin affinity plasmapheresis in a patient with severe Ebola virus disease. © 2015 S. Karger AG, Basel.

Correct postoperative management is fundamental to prevent and treat complications and to optimize the success of filtering surgery. Timely control visits and appropriate actions and prescriptions ensure the best outcomes, allow recovery from a number of untoward events, and can reestablish filtration when failure seems imminent. In contrast, a slack follow-up and wrong interventions or prescriptions can lead to the failure of any surgery, no matter how accurately it was carried out, sometimes jeopardizing vision and even the anatomy of the globe. The purpose of this review is to present a rational approach to postoperative follow-up and to synthetically describe how to prevent, recognize and address the most common complications of filtering surgery, pointing out the most common pitfalls in the management of the operated eye. © 2017 S.

Challenges of the Transition from Pediatric Care to Care of Adults: "Say Goodbye, Say Hello".

Touraine, Philippe; Polak, Michel

2018-01-01

Transition has been defined as "the purposeful, planned movement of adolescents and young adults with chronic physical and medical conditions from child-centered to adult-oriented health care systems." We will here describe the challenges of such a process: challenges coming from the pediatrician, from the adolescent, linked to the disease itself, and those from the parents. We will outline how to overcome those fears and challenges to provide a successful transition process. A key factor to underline that process is that a relationship based on confidence should be established between the pediatrician and the physician for adults, in order for that relationship, based on trust, to be the basis for the transfer of the adolescent from the pediatric system of care to the adult one. © 2018 S.

The case for vaccinating boys against human papillomavirus.

PubMed

Hull, Sarah C; Caplan, Arthur L

2009-01-01

Vaccination policy in the case of human papillomavirus (HPV) has remained a constant source of controversy ever since Gardasil, Merck's vaccine against HPV, received US Food and Drug Administration approval in the summer of 2006. This controversy has centered on the risks and benefits of vaccinating girls and women in rich and poor nations alike. However, despite all of the attention created by this important policy question, relatively little has been focused on another key public health question: should boys be vaccinated against HPV as well? If herd immunity against the most carcinogenic strains of HPV could be more rapidly and efficiently achieved by vaccinating everyone at risk for being a carrier, it logically follows that vaccine policy should expand to include boys and men.

An analysis of eye health care in the Czech Republic as of 1998 was performed. A questionnaire was used to obtain information from all 59 in-patient eye departments. The number of ophthalmologists per 1 million inhabitants was 95. The number of cataract operations per 1 million inhabitants was 4,209: phaco-emulsification (36,926 surgeries, 85.2%), extracapsular extraction (6,094 surgeries, 14.1%) and intracapsular extraction (90 surgeries, 0.2%). Intra-ocular lenses were implanted in 99% of cases; 404 corneal transplantations and 1,220 operations for retinal detachment were performed. The number of pars plana vitrectomies for diabetic eye complications was 661. Selected regional clinical centres should be equipped and preferred by health insurance companies to provide comprehensive eye health care services and training. Copyright 2002 S. Karger AG, Basel

Activity budget and ranging patterns of Colobus vellerosus in forest fragments in central Ghana.

Wong, Sarah N P; Sicotte, Pascale

2007-01-01

The forest fragments surrounding the 192-ha Boabeng-Fiema Monkey Sanctuary (BFMS) in central Ghana contain small populations of Colobus vellerosus. Data were collected on activity budget, ranging patterns and habitat use of 3 groups living in these small fragments in August-November 2003, and compared to 3 BFMS groups. Fragment groups spent less time moving and more time resting than BFMS groups. Home ranges of fragment groups tended to be smaller than those of BFMS groups. Fragment and BFMS groups used similarly sized trees. Comparisons of activity budget and ranging between fragments and the BFMS suggest that fragment habitat quality was sufficient to sustain current numbers. These behavioral trends are consistent with a concurrent study that we conducted investigating ecological quality in the same fragments. Copyright 2007 S. Karger AG, Basel.

Pituitary gland development: an update.

Bancalari, Rodrigo E; Gregory, Louise C; McCabe, Mark J; Dattani, Mehul T

2012-01-01

The embryonic development of the pituitary gland involves a complex and highly spatio-temporally regulated network of integrating signalling molecules and transcription factors. Genetic mutations in any of these factors can lead to congenital hypopituitarism in association with a wide spectrum of craniofacial/midline defects ranging from incompatibility with life to holoprosencephaly (HPE) and cleft palate and septo-optic dysplasia (SOD). Increasing evidence supports a genotypic overlap with hypogonadotrophic hypogonadal disorders such as Kallmann syndrome, which is consistent with the known overlap in phenotypes between these disorders. This chapter reviews the cascade of events leading up to the successful development of the pituitary gland and to highlight key areas where genetic variations can occur thus leading to congenital hypopituitarism and associated defects.

Validated cognitive screening tools for use in urban and regional Aboriginal populations in Australia are lacking. In a cross-sectional community-based study, 235 participants were assessed on the Mini-Mental State Examination (MMSE), the Rowland Universal Dementia Assessment Scale (RUDAS) and an urban modification of the Kimberley Indigenous Cognitive Assessment (mKICA). Performance on these cognitive screening tools was compared to dementia diagnosis by clinical consensus. All tests were culturally acceptable with good psychometric properties. Receiver operating characteristic curve analyses revealed that the MMSE and mKICA were the most accurate. The MMSE is an effective cognitive screening tool in urban Aboriginal populations. The mKICA is a good alternative when illiteracy, language or cultural considerations deem it appropriate. The RUDAS also has adequate validity in this population. © 2015 S. Karger AG, Basel.

Influence of punishment, emotional rejection, child abuse, and broken home on aggression in adolescence: an examination of aggressive adolescents in Germany.

PubMed

Barnow, S; Lucht, M; Freyberger, H J

2001-01-01

The results of this study provide evidence for the importance of psychosocial risks in childhood for aggressive behavior in adolescence. This study demonstrated that aggressive adolescents differed from a nonaggressive control group in an increased exposure to prior psychotraumatic events, such as sexual abuse (tendency), physical abuse, and broken homes. However, in predicting later aggressive behavior, long-term and chronically effective negative living conditions seem of greater importance. Parenting behavior which includes harsh punishment and emotional rejection as well as separation of the parents early in life are particularly important factors. Whereas aggressive girls do not differ from the nonaggressive control group in terms of self-reported mental health, the aggressive boys reported more attention deficits, depression, anxiety, delinquency, and social problems.

Nutrition plays a key role in allowing the numerous training hours to be translated into useful adaptive responses of various tissues in the individual athlete. Research over the last decade has shown many examples of the impact of dietary interventions to modulate the skeletal muscle adaptive response to prolonged exercise training. Proper nutritional coaching should be applied throughout both training and competition, each with their specific requirements regarding nutrient provision. Such dietary support will improve exercise training efficiency and, as such, further increase performance capacity. Here, we provide an overview on the properties of various nutritional interventions that may be useful to support the adaptive response to exercise training and competition and, as such, to augment exercise training efficiency.

The chromosomal complement of the artedidraconid fish Histiodraco velifer (Perciformes: Notothenioidei) from Terra Nova Bay, Ross Sea.

Caputo, V; Splendiani, A; Nisi Cerioni, P; Olmo, E

2003-01-01

The karyotype of Histiodraco velifer from the Antartic Ocean was analyzed using various banding methods and in situ hybridization with a telomeric probe. A male and a female had a diploid set of 46 chromosomes (6 submetacentric + 40 acrocentric, FN = 52); the nucleolar organizer was CMA3-positive and was located on the short arm of a medium-sized submetacentric pair. All chromosomes stained uniformly with DAPI, whereas C-banding revealed heterochromatic blocks that were mostly located centromerically and telomerically and were resistant to ALUI digestion. The substantial identity of the karyotype of H. velifer with that of the other artedidraconids investigated so far suggests that chromosome changes must have played a less than significant role in the speciation among the lineages of this fish family endemic to Antarctica.

Motivational interviewing to engage patients in chronic kidney disease management.

PubMed

Martino, Steve

2011-01-01

Patients with chronic kidney disease (CKD) must manage numerous medical treatments and lifestyle changes that strain their treatment adherence. An important strategy to improve adherence is to activate the patients' motivation to manage their CKD. This article describes an approach for enhancing patients' motivation for change, called motivational interviewing (MI), a treatment that is increasingly being used in health care settings to counsel patients with chronic diseases. Its basic principles, techniques, empirical support, published applications for improving CKD patients' self-management, and how to learn MI are presented. Research is needed to determine the efficacy and mechanisms of MI for CKD treatment as well as the development of innovative ways to deliver it to patients and train busy health care practitioners in the approach.

In recent years, epidemiological data has demonstrated that alcohol consumption is a risk factor for sunburn, melanoma and nonmelanoma skin cancer. We hypothesized that if the concentration of the antioxidants in the skin has already decreased due to alcohol consumption, then an adequate neutralization of the free radicals induced by ultraviolet light cannot be performed. Based on this hypothesis, we determined the carotenoid concentration in the skin and the minimal erythema dose (MED) of 6 male human volunteers before and after consumption of alcohol or alcohol and orange juice combined. The results showed a significant decrease in the carotenoid concentration in the skin and the MED after alcohol consumption, but no significant decrease after a combined intake of alcohol and orange juice.

Aging and the Kidneys: Anatomy, Physiology and Consequences for Defining Chronic Kidney Disease.

PubMed

Glassock, Richard J; Rule, Andrew D

2016-01-01

The varied functions of the kidneys are influenced by the complex process of aging. The glomerular filtration rate (GFR) steadily declines with normal aging, and the progress of this process can be influenced by superimposed diseases. Microscopically, nephron numbers decrease as global glomerulosclerosis becomes more evident. The precise mechanisms underlying nephron loss with aging are not well understood, but derangements in podocyte biology appear to be involved. Classifications of chronic kidney disease (CKD) incorporate GFR values and attendant risk of adverse events. Arbitrary and fixed thresholds of GFR for defining CKD have led to an overdiagnosis of CKD in the elderly. An age-sensitive definition of CKD could offer a solution to this problem and more meaningfully capture the prognostic implications of CKD. © 2016 S. Karger AG, Basel.

2012-01-01

Research in cell biology and the development of translational technologies are driven by competition, public expectations, and regulatory oversight, putting these fields at a critical juncture. Success in these fields is quickly becoming dependent on the ability of researchers to identify and isolate specific cell populations from heterogeneous mixtures accurately and efficiently. Many methods for cell purification have been developed, and each has advantages and disadvantages that must be considered in light of the intended application. Current cell separation strategies make use of surface proteins, genetic expression, and physics to isolate specific cells by phenotypic traits. Cell purification is also dependent on the cellular reagents available for use and the intended application, as these factors may preclude certain mechanisms used in the processes of labeling and sorting cells.

Does dissociation offer a useful explanation for psychopathology?

PubMed

Jureidini, Jon

2004-01-01

Dissociation is often conceptualised as an altered state of consciousness, a trance-like state in which normal barriers between conscious and unconscious memories, desires and beliefs break down and other amnestic barriers emerge. This review explores whether it is likely that there is a neurophysiology of pathological dissociative processes that will elucidate management. A critical reading of current research, sourced through Medline and Psychinfo searches from 1990 to 2002, using subject headings: dissociative disorders, hypnosis and stress disorder (post-traumatic), as well as keywords: dissociation, hypnosis and trance. Current knowledge does not support the notion of dissociation as a discrete brain state or process. Psychiatric and neurophysiological research and theory development are better directed towards individual components that contribute to dissociative experience. Copyright (c) 2004 S.

Portuguese Lexical Clusters and CVC Sequences in Speech Perception and Production.

Cunha, Conceição

2015-01-01

This paper investigates similarities between lexical consonant clusters and CVC sequences differing in the presence or absence of a lexical vowel in speech perception and production in two Portuguese varieties. The frequent high vowel deletion in the European variety (EP) and the realization of intervening vocalic elements between lexical clusters in Brazilian Portuguese (BP) may minimize the contrast between lexical clusters and CVC sequences in the two Portuguese varieties. In order to test this hypothesis we present a perception experiment with 72 participants and a physiological analysis of 3-dimensional movement data from 5 EP and 4 BP speakers. The perceptual results confirmed a gradual confusion of lexical clusters and CVC sequences in EP, which corresponded roughly to the gradient consonantal overlap found in production. © 2015 S.

Lexical priming was examined in patients with Alzheimer's disease and in aphasic patients. Control participants were divided into young and elderly [cf. Arroyo-Anlló et al.: Eur J Cogn Psychol 2004;16:535-553]. For lexical priming, a word-stem completion task was used. Normal elderly participants had lexical priming scores that were significantly lower than those of young individuals. Analysis of covariance with age and educational level as covariates showed that the control participants, aphasic and Alzheimer patients did not differ significantly on the lexical priming task. Our results suggest that performance in the lexical priming task diminishes with physiological aging, but is not significantly affected by mild or moderate Alzheimer's disease or by fluent or non-fluent aphasia.

We treated an extremely tall 13-year-old girl with a growth hormone (GH)-secreting macroadenoma and GH levels of 120-495 ng/ml with a combination of preoperative octreotide infusion, surgery and postoperative octreotide infusion plus estrogen, which resulted in reduced tumor size prior to surgery, reduced GH levels and completely suppressed growth after surgery. 20K GH is produced by alternative splicing of 22K GH mRNA and the ratio of 20K GH to 22K GH is within a small range in the normal population and high in a GH-secreting tumor. The 20K/22K GH ratio in this patient was persistently elevated during each phase of the treatment and may serve as a sensitive index of tumor-derived GH secretion. Copyright 2000 S.

2006-01-01

We ascertained a large Italian family with an autosomal dominant form of non-syndromic sensorineural hearing loss with vestibular involvement. A genome-wide scan found linkage to locus DFNA11. Sequencing of the MYO7A gene in the linked region identified a new missense mutation resulting in an Ala230Val change in the motor domain of the myosin VIIA. Myosin VIIA has already been implicated in several forms of deafness, but this is the third mutation causing a dominant form of deafness, located in the myosin VIIA motor domain in a region never involved in hearing loss until now. A modelled protein structure of myosin VII motor domain provides evidence for a significant functional effect of this missense mutation. Copyright (c) 2006 S. Karger AG, Basel.

The wage of fame: how non-epistemic motives have enabled the phenomenal success of modern science.

PubMed

Franck, Georg

2015-01-01

This paper ventures an economic view of modern science. It points out how science works as a closed economy of attention where researchers invest their own attention in order to get the attention of fellow researchers. Attention thus enters economy in two properties: (1) as a scarce resource energising scientific production and (2) as a means of gratification rewarding the effort of the working scientist. Economising on attention as a scarce resource is another expression of thought economy. The income of expert attention is what gives rise to reputation, renown, prominence and eventually fame. By its being conceived as a closed economy of attention, science shows to be capable of self-organising a tendency towards overall efficiency and thus towards collective rationality. © 2014 S.

Practical Issues in Vitamin D Replacement.

Adler, Robert A

2018-01-01

Practical clinical guidance for vitamin D assessment and management relies on a strong evidence base, but unfortunately there are many deficiencies in our current knowledge. For the general population the Institute of Medicine recommendations are likely to provide adequate vitamin D levels without harms. Thus, most adults should ingest 600-800 IU (international units) in diet and supplements with up to 4,000 IU daily likely to be safe. In certain populations, such as those with osteoporosis or after bariatric surgery, it is important to know the levels of circulating 25-hydroxyvitamin D, but general screening has not been shown to improve health. One expert group has recommended a "reasonable" level of 30 ng/mL in those individuals for whom testing is required. © 2018 S. Karger AG, Basel.

Artistic creativity, style and brain disorders.

The production of novel, motivated or useful material defines creativity, which appears to be one of the higher, specific, human brain functions. While creativity can express itself in virtually any domain, art might particularly well illustrate how creativity may be modulated by the normal or pathological brain. Evidence emphasizes global brain functioning in artistic creativity and output, but critical steps which link perception processing to execution of a work, such as extraction-abstraction, as well as major developments of non-esthetic values attached to art also underline complex activation and inhibition processes mainly localized in the frontal lobe. Neurological diseases in artists provide a unique opportunity to study brain-creativity relationships, in particular through the stylistic changes which may develop after brain lesion. (c) 2005 S.

History of research on angiogenesis.

Ribatti, Domenico

2014-01-01

Over the past 25 years, the number of Medline publications dealing with angiogenesis has increased in a nonlinear fashion, reflecting the interest among basic scientists and clinicians in this field. Under physiological conditions, angiogenesis is regulated by the local balance between endogenous stimulators and inhibitors of this process. In tumor growth, there is an imbalance between endogenous stimulator and inhibitor levels, leading to an 'angiogenic switch'. Starting with the hypothesis formulated by Judah Folkman that tumor growth is angiogenesis-dependent, this area of research has a solid scientific foundation and inhibition of angiogenesis is a major area of therapeutic development for the treatment of cancer. This paper offers an account of the most relevant discoveries in this field of biomedical research. Copyright © 2014 S. Karger AG, Basel.

Inducing Sex Reversal in Marsupial Mammals.

PubMed

Chew, Keng Y; Renfree, Marilyn B

2016-01-01

Marsupials are born with undifferentiated gonads, and their reproductive organs differentiate consecutively, not simultaneously as in eutherian mammals. Thus, in the main marsupial model, the tammar wallaby, Macropus eugenii, the testis forms cords 2 days after birth, the ovary develops cortex and medulla about 8 days after birth, the Wolffian duct enlarges from day 10, the prostate begins to form prostatic buds about 25 days after birth, and the phallus does not become sexually dimorphic until after 50 days postpartum (pp). The brain responses also become sexually dimorphic relatively late in development, after day 25 pp. This relatively elongated period of differentiation has allowed experimental manipulation at each stage of development to induce often dramatic sex reversal of both internal and external genitalia. © 2016 S.

Sarcoidosis is a rare, systemic disease that is characterized by the formation of granulomas in various organs, including the skin. As the etiology remains unknown, the treatment of sarcoidosis is challenging. We present a 47-year-old female patient with progressive, multi-organ sarcoidosis who had a complete clinical improvement of the skin lesions, a moderate reduction in pulmonary opacities on chest X-ray, a marked subjective improvement in general status and pulmonary efficiency and a marked reduction in serum angiotensin-converting enzyme and soluble interleukin-2 receptor after 6 months of therapy with fumaric acid esters. The present case and similar reports in the literature highlight the probable efficacy of fumaric acid esters in the treatment of sarcoidosis and other non-infectious, granulomatous diseases. © 2014 S.

We report a case of acute interstitial nephritis (AIN) due to nicergoline (Sermion). A 50-year-old patient admitted to our hospital for fever and acute renal failure. Before admission, he had been taking nicergoline and bendazac lysine due to retinal vein occlusion at ophthalmologic department. Thereafter, he experienced intermittent fever and skin rash. On admission, clinical symptoms (i.e. arthralgia and fever) and laboratory findings (i.e. eosinophilia and renal failure) suggested AIN, and which was confirmed by pathologic findings on renal biopsy. A lymphocyte transformation test demonstrated a positive result against nicergoline. Treatment was consisted of withdrawal of nicergoline and intravenous methylprednisolone, and his renal function was completely recovered. To our knowledge, this is the first report of nicergoline-associated AIN. Copyright 2002 S. Karger AG, Basel

Use of the International Pharmaceutical Federation’s Basel Statements to Assess and Advance Hospital Pharmacy Practice: A Scoping Review

PubMed Central

Penm, Jonathan; Chaar, Betty; Moles, Rebekah J

2016-01-01

Background: The Basel statements of the International Pharmaceutical Federation, which provide the first global, unified vision for the hospital pharmacy profession, have recently been revised. Originally released in 2008, the Basel statements have since been made available in 21 languages, and thus have the potential for great impact around the world. Objective: To conduct a scoping review to examine the extent and nature of research activity related to the Basel statements. Methods: Google Scholar, PubMed, and International Pharmaceutical Abstracts were searched using the key term “Basel statements” for relevant research articles. From each included study, data were extracted on geographic location, study design, study outcomes, and use of the Basel statements. Results: The search strategy generated 113 results. Further refinement resulted in 14 English-language articles that met the inclusion criteria. Four of these articles focused on adapting the Basel statements to European practice, an initiative of the European Association of Hospital Pharmacists that led to development of the European statements of Hospital Pharmacy. Six studies focused on monitoring hospital pharmacy practice in Uganda, the Pacific island countries, and the Western Pacific Region. These studies provide valuable baseline data to measure and track the development of hospital pharmacy practices in their respective countries and regions. The remaining 4 studies used qualitative methods to explore the barriers to and facilitators of implementation of the Basel statements in South Africa, China, and Australia. Conclusion: The Basel statements have led to multiple initiatives around the world, involving more than 70 countries. The European and Western Pacific regions have been the most active. Current initiatives should be continued to ensure identification and resolution of issues related to sustaining their use over time. PMID:27168634

At the Centennial Exhibition of the Nobel Prize, the Nobel Foundation called it one of the ten cradles of creativity. The journal Nature likened its ideals to those of the French revolution--Liberté, Egalité, Fraternité--and called it a paradise devoted to the science of immune systems: the Basel Institute for Immunology (BII). Founded by Roche in 1968, inaugurated in 1971, and closed in 2000, it was home to almost 450 scientific members, over 1,000 scientific visitors, and nearly 100 scientific advisors from more than 30 countries who worked in complete academic freedom and without commercial motives on over 3,500 projects, publishing more than 3,200 scientific papers, almost all of them on the structure and functions of immune systems of different species. This review contains a first collection of historical facts and dates that describe the background of the exceptionally successful performance and the strong scientific impact of the institute on the field of immunology.

Astragaloside (AGS) extracted from radix astragalin (Huangqi) has been considered to be beneficial to liver diseases. In this study, we examined the role played by AGS in alleviating hepatic fibrosis function via protease-activated receptor-2 (PAR2) mechanisms. We hypothesized that AGS affects PAR2 signaling pathway thereby improving hepatic function in rats with hepatic fibrosis induced by carbon tetrachloride (CCl4). We further hypothesized that AGS attenuates impaired hepatic function evoked by CCl4 to a greater degree in diabetic animals. ELISA and Western Blot analysis were used to examine PAR2 signaling pathway in diabetic CCl4-rats and non-diabetic CCl4-rats. AGS inhibited the protein expression of PAR2 and its downstream pathway PKA and PKCɛ in CCl4-rats. Notably, the effects of AGS were greater in CCl4-rats with diabetes. AGS also significantly attenuated the CCl4-induced upregulations of pro-inflammatory cytokines, namely interleukin-1β, interleukin-6 and tumor necrosis factor-α accompanied with decreases of collagenic parameters such as hexadecenoic acid, laminin and hydroxyproline. Additionally, AGS improved the CCl4-induced exaggerations of liver index and functions including alanine aminotransferase, aspartate aminotransferase. Moreover, TGF-β1, a marker of hepatic fibrosis, was increased in CCl4-rats and AGS inhibited increases in TGF-β1 induced by CCl4. AGS alleviates hepatic fibrosis by inhibiting PAR2 signaling expression and its effects are largely enhanced in diabetic animals. Targeting one or more of these signaling molecules may present new opportunities for treatment and management of hepatic fibrosis; and results of our study are likely to shed light on strategies for application of AGS because it has potentially greater therapeutic effectiveness for hepatic fibrosis in diabetes. © 2017 The Author(s)Published by S.

Helminths induce type 2 immune responses and establish an anti-inflammatory milieu in their hosts. This immunomodulation was previously shown to improve diet-induced insulin resistance which is linked to chronic inflammation. In the current study, we demonstrate that infection with the filarial nematode Litomosoides sigmodontis increased the eosinophil number and alternatively activated macrophage abundance within epididymal adipose tissue (EAT) and improved glucose tolerance in diet-induced obese mice in an eosinophil-dependent manner. L. sigmodontis antigen (LsAg) administration neither altered the body weight of animals nor adipose tissue mass or adipocyte size, but it triggered type 2 immune responses, eosinophils, alternatively activated macrophages, and type 2 innate lymphoid cells in EAT. Improvement in glucose tolerance by LsAg treatment remained even in the absence of Foxp3+ regulatory T cells. Furthermore, PCR array results revealed that LsAg treatment reduced inflammatory immune responses and increased the expression of genes related to insulin signaling (Glut4, Pde3b, Pik3r1, and Hk2) and fatty acid uptake (Fabp4 and Lpl). Our investigation demonstrates that L. sigmodontis infection and LsAg administration reduce diet-induced EAT inflammation and improve glucose tolerance. Helminth-derived products may, therefore, offer new options to improve insulin sensitivity, while loss of helminth infections in developing and developed countries may contribute to the recent increase in the prevalence of type 2 diabetes. © 2016 S.

WZhet is a rearranged and partially deleted form of the Epstein-Barr virus (EBV) genome in which the BamH1W region becomes juxtaposed with and activates BZLF1, resulting in constitutive viral replication. We tested whether WZhet induces viral replication in epithelial cells, and we studied its prevalence in a wide range of lesional tissues arising in vivo. A quantitative real-time PCR assay targeting EBV WZhet DNA was developed to measure this recombinant form of the EBV genome. WZhet DNA was undetectable in any of 324 plasma or paraffin-embedded tissue samples from patients with EBV-associated and EBV-negative disorders. These included specimens from patients with Hodgkin or non-Hodgkin lymphoma, post-transplant lymphoproliferation, nasopharyngeal or gastric adenocarcinoma, and infectious mononucleosis. However, WZhet DNA was detected in vitro in EBV-infected AGS gastric cancer cells. Additionally, transient transfection of infected AGS gastric cancer cells showed that viral replication could be induced by a WZhet plasmid. This is the first evidence that WZhet induces the EBV lytic cycle in an epithelial cell line. Our negative findings in natural settings suggest that WZhet is a defective viral product that thrives in the absence of a host immune system but is rarely present in vivo. Copyright 2009 S.

Early-Onset Central Diabetes Insipidus due to Compound Heterozygosity for AVP Mutations.

PubMed

Bourdet, Karine; Vallette, Sophie; Deladoëy, Johnny; Van Vliet, Guy

2016-01-01

Genetic cases of isolated central diabetes insipidus are rare, are mostly due to dominant AVP mutations and have a delayed onset of symptoms. Only 3 consanguineous pedigrees with a recessive form have been published. A boy with a negative family history presented polyuria and failure to thrive in the first months of life and was diagnosed with central diabetes insipidus. Magnetic resonance imaging showed a normal posterior pituitary signal. A molecular genetic analysis of the AVP gene showed that he had inherited a previously reported mutation from his Lebanese father and a novel A>G transition in the splice acceptor site of intron 1 (IVS1-2A>G) from his French-Canadian mother. Replacement therapy resulted in the immediate disappearance of symptoms and in weight gain. The early polyuria in recessive central diabetes insipidus contrasts with the delayed presentation in patients with monoallelic AVP mutations. This diagnosis needs to be considered in infants with very early onset of polyuria-polydipsia and no brain malformation, even if there is no consanguinity and regardless of whether the posterior pituitary is visible or not on imaging. In addition to informing family counseling, making a molecular diagnosis eliminates the need for repeated imaging studies. © 2015 S. Karger AG, Basel.

Vulvovaginitis and other common vulvar disorders in children.

Rome, Ellen S

2012-01-01

Vulvovaginitis, labial adhesions, and other vulvar disorders occur commonly in children and can provoke high anxiety in both the parent and child. Performed correctly, the pediatric gynecologic examination can diagnose and treat, educate and reassure both parent and child. This examination requires patience, sensitivity, direct communication with the child as well as with the parent, and an open manner that inspires trust in both parties to manage a potentially anxiety-provoking situation. This chapter will review common vulvar disorders, including vulvovaginitis, lichen sclerosis et atrophicus, bubble bath vaginitis, labial adhesions, urethral prolapse, and other common problems. A discussion of childhood sexual abuse is beyond the scope of this chapter, with appropriate references available elsewhere. Practical pearls will be offered to make this exam easy for the primary care clinician and/or subspecialist. Copyright © 2012 S. Karger AG, Basel.

The Hypothalamic-Pituitary-Adrenal Axis and the Fetus.

PubMed

2018-06-06

Glucocorticoids (GCs), cortisol in humans, influence multiple essential maturational events during gestation. In the human fetus, fetal hypothalamic-pituitary-adrenal (HPA) axis function, fetal adrenal steroidogenesis, placental 11β- hydroxysteroid dehydrogenase type 2 activity, maternal cortisol concentrations, and environmental factors impact fetal cortisol exposure. The beneficial effects of synthetic glucocorticoids (sGCs), such as dexamethasone and betamethasone, on fetal lung maturation have significantly shifted the management of preterm labor and threatened preterm birth. Accumulating evidence suggests that exposure to sGCs in utero at critical developmental stages can alter the function of organ systems and that these effects may have sequelae that extend into adult life. Maternal stress and environmental influences may also impact fetal GC exposure. This article explores the vulnerability of the fetal HPA axis to endogenous GCs and exogenous sGCs. © 2018 S.

We run Exploratory and Confirmatory Factor Analyses of the Minnesota Nicotine Withdrawal Scale (MNWS) and of the MNWS-Revised (MNWS-R). Psychometric properties were also explored. Adult Italian smokers, 366 in all, were assessed via the MNWS-R together with rating scales measuring cigarette dependence, alcohol use, anxiety sensitivity and negative affect at baseline and after 3 months. The MNWS showed good psychometric properties (α = 0.85; rtt = 0.59) and a unidimensional factor structure. The 2-factor model of MNWS-R had the best fit and the factors were labelled psychological symptoms (α = 0.86; rtt = 0.59) and associated somatic features (α = 0.64; rtt = 0.45). MNWS showed 1 factor; MNWS-R showed 2 relatively dependent factors. The results need to be replicated in smokers in withdrawal. © 2017 S. Karger AG, Basel.

Osteoporosis in Children with Chronic Disease.

Högler, Wolfgang; Ward, Leanne

Serious illness in children and its therapy can cause osteoporosis, manifesting as vertebral and nonvertebral fractures, pain, skeletal deformity and temporary or even permanent loss of ambulation. In contrast to adults, skeletal growth in children offers tremendous potential to recover bone mineral density and to reshape fractured vertebral bodies, even without bone-targeted therapy, provided that bone health threats are transient and residual growth is sufficient. Here, we outline the principles of bone strength development and the risk factors for osteoporosis due to various paediatric systemic illnesses. We also explain why the approach to the diagnosis and monitoring of childhood osteoporosis has moved away from a bone density-centric focus to a more functional assessment. Finally, we discuss the best candidates for and current approaches to the treatment of osteoporosis in children. © 2015 S. Karger AG, Basel.

Uremic pruritus (UP) is an unpleasant complication in patients undergoing maintenance dialysis. Cardiovascular and infection related deaths are the major causes of mortality in patients undergoing dialysis. Studies on the correlation between cardiovascular or infection related mortality and UP are limited. We analyze 866 maintenance hemodialysis (MHD) patients in our hemodialysis centers. Clinical parameters and 24-month cardiovascular and infection-related mortality are recorded. The associations between all-cause, cardiovascular and infection related mortality with clinical data including UP are analyzed. Multivariate Cox regression demonstrated that UP is a significantly predictor for 24-month cardiovascular mortality in the MHD patients (Hazard ratio: 3.164; 95% confidence interval, 1.743-5.744; p < 0.001). Uremic pruritus is one of the predictor of 24-month cardiovascular mortality in MHD patients. © 2018 The Author(s). Published by S. Karger AG, Basel.

A New Pathogenesis of Albuminuria: Role of Transcytosis.

2018-06-15

Transcytosis is an important intracellular transport process by which multicellular organisms selectively move cargoes from apical to basolateral membranes without disrupting cellular homeostasis. In kidney, macromolecular components in the serum, such as albumin, low-density lipoprotein and immunoglobulins, pass through the glomerular filtration barrier (GFB) and proximal tubular cells (PTCs) by transcytosis. Protein transcytosis plays a vital role in the pathology of albuminuria, which causes progressive destruction of the GFB structure and function. However, the pathophysiological consequences of protein transcytosis in the kidney remain largely unknown. This article summarizes recent researches on the regulation of albumin transcytosis across the GFB and PTCs in both physiological and pathological conditions. Understanding the mechanism of albumin transcytosis may reveal potential therapeutic targets for prevention or alleviation of the pathological consequences of albuminuria. © 2018 The Author(s).

Anschau, Fernando; Guimarães Gonçalves, Manoel Afonso

2011-01-01

Since cytology is the examination utilized for the screening of cervical cancer, it is important to determine its correlation with histologic examination, the gold standard in the diagnosis of cervical disease. A retrospective evaluation was made of 431 patients who presented with colposcopic indication for cervical biopsy between 2003 and 2007. In 90.8% (289/318) of the patients, cytology showing cervical intraepithelial neoplasia (CIN) was confirmed as CIN in the histology of the cervix, while 62.8% (71/113) of patients with normal cytology had a confirmation of a normal histology (κ = 0.558). Cytology demonstrated a sensitivity and specificity of 87.3 and 71.0%, respectively. The agreement between cervical cytology and histology, considering the presence of CIN, was moderate. Correlations between accuracy and errors of cytology are discussed with therapeutic emphasis. Copyright © 2011 S. Karger AG, Basel.

EU actions to ensure the safety of tattoos and the protection of consumers.

2015-01-01

The number of tattooed persons has been continuously increasing in the last few years, particularly in the younger population. At the same time, the possibility of purchasing tattoo inks online is easier than ever worldwide. Consumers are not always sufficiently aware of the possible health problems associated with this 'cool fashion' if hygiene conditions are not respected and/or if the injected mixtures contain dangerous chemicals. Concerns about the possible health risks associated with such practices arise from the absence of a clear legislative framework, the lack of proper risk assessment of the chemicals used, and non-harmonised or missing hygiene and purity requirements, among other factors. There is a general consensus among all active stakeholders that EU harmonised rules would help to ensure a consistent high level of protection of consumers across the EU. © 2015 S. Karger AG, Basel.

Autoantibodies in Autoimmune Hepatitis.

The detection of diagnostic autoantibodies such as antinuclear antibodies (ANA), anti-smooth muscle antibodies (SMA), anti-liver/kidney microsomal type 1 (anti-LKM1), anti-liver cytosol type 1 (anti-LC1) and anti-soluble liver antigen (anti-SLA) is historically associated with the diagnosis of autoimmune hepatitis. When autoimmune hepatitis is suspected, the detection of one or any combination of diagnostic autoantibodies, by indirect immunofluorescence or immuno-enzymatic techniques with recombinant antigens, is a pivotal step to reach a diagnostic score of probable or definite autoimmune hepatitis. Diagnostic autoantibodies (ANA, SMA, anti-LKM1, anti-LC1, anti-SLA) are a cornerstone in the diagnosis of autoimmune hepatitis. Other ancillary autoantibodies, associated with peculiar clinical correlations, appear to be assay-dependent and institution-specific, and validation studies are needed. © 2015 S. Karger AG, Basel.

Clinimetrics and clinical psychometrics: macro- and micro-analysis.

PubMed

Tomba, Elena; Bech, Per

2012-01-01

Clinimetrics was introduced three decades ago to specify the domain of clinical markers in clinical medicine (indexes or rating scales). In this perspective, clinical validity is the platform for selecting the various indexes or rating scales (macro-analysis). Psychometric validation of these indexes or rating scales is the measuring aspect (micro-analysis). Clinical judgment analysis by experienced psychiatrists is included in the macro-analysis and the item response theory models are especially preferred in the micro-analysis when using the total score as a sufficient statistic. Clinical assessment tools covering severity of illness scales, prognostic measures, issues of co-morbidity, longitudinal assessments, recovery, stressors, lifestyle, psychological well-being, and illness behavior have been identified. The constructive dialogue in clinimetrics between clinical judgment and psychometric validation procedures is outlined for generating developments of clinical practice in psychiatry.

Starch is one of the most popular nutritional sources for both human and animals. Due to the variation of its nutritional traits and biochemical specificities, starch has been classified into rapidly digestible, slowly digestible and resistant starch. Resistant starch has its own unique chemical structure, and various forms of resistant starch are commercially available. It has been found being a multiple-functional regulator for treating metabolic dysfunction. Different functions of resistant starch such as modulation of the gut microbiota, gut peptides, circulating growth factors, circulating inflammatory mediators have been characterized by animal studies and clinical trials. In this mini-review, recent remarkable progress in resistant starch on gut microbiota, particularly the effect of structure, biochemistry and cell signaling on nutrition has been summarized, with highlights on its regulatory effect on gut microbiota. © 2017 The Author(s).

Cebus/Sapajus has shown high cognitive and manipulatory behaviour as well as intermittent bipedalism. Although the function of the muscles and bones of this genus has been widely investigated, the arterial system that supports these tissues has not been studied in much detail, and a full description of the blood vessels of the pelvis is still missing. Therefore, we studied the vessels of the pelvis of Sapajus libidinosus in terms of their origin, distribution and muscle irrigation and compared them with those of other primates available in the literature. In general, the distribution pattern and origin of arteries in the pelvis of the bearded capuchin are more similar to those of baboons compared to other primates. This similarity may be because both have a tail, a similar body shape and use, preferentially, quadrupedal movement. 2014 S. Karger AG, Basel

The centromeric region of rat chromosome 2 (2q1) harbors unidentified quantitative trait loci of genes that control tumor growth or development. To improve the mapping of this chromosome region, we microdissected it and generated 10 new microsatellite markers, which we included in the linkage map and/or radiation hybrid map of 2q1, together with other known markers, including four genes: Pcsk1 (protein convertase 1), Dhfr (dihydrofolate reductase), Ndub13 (NADH ubiquinone oxidoreductase subunit b13), and Ccnb1 (cyclin B1). To generate anchor points between the different maps, the gene Ndub13 and the microsatellite markers D2Ulb25 and D2Mit1 were also localized cytogenetically. The radiation map generated in region 2q1 extends its centromeric end of about 150 cR. Copyright 2000 S. Karger AG, Basel

We have recently shown that ischemic stroke causes a stress-mediator-induced long-lasting immunodepressive state in mice. Using head magnetic resonance imaging and standardized immunoassays, we prospectively investigated whether poststroke immunodepression is also seen in humans. Compared to healthy volunteers (n = 30), a rapid depression of lymphocyte counts and a functional deactivation of monocytes and T helper type 1 cells was observed in acute stroke patients (SP; n = 40). Immunodepression was more pronounced in patients with severe clinical deficit or large infarction. On admission the combination of monocytic tumor necrosis factor alpha release ex vivo and the National Institute of Health Stroke Scale score were the best predictors for nosocomial infection, preferentially affecting older SP. Our data provide evidence for an immediate suppression of cell-mediated immune responses after ischemic stroke in humans. (c) 2007 S. Karger AG, Basel.

2008-01-01

Chromosome numbers in Cyperaceae lower than the typical basic number x = 5 have been described for only three species: Rhynchospora tenuis (n = 2), Fimbristylis umbellaris (n = 3) and Eleocharis subarticulata (n = 3). Eleocharis maculosa is recorded here as the fourth species of Cyperaceae that has a chromosome number lower than 2n = 10, with 2n = 8, 7 and 6. The karyotype differentiation in E. maculosa was studied using conventional staining (mitosis and meiosis), FISH with 45S and 5S rDNA and telomere probes. The results allow us to determine which chromosomes of the chromosome race with 2n = 10 fused to form the remaining reduced numbers, as well as to understand how the symploidy and translocation mechanisms were important in karyotype differentiation and the formation of chromosome races in Eleocharis.

A case of diprosopus twinning which is rare conjoined twinning is reported prenatally at 22 weeks' gestation. 2D ultrasound examinations showed duplication of the craniofacial structures with four hemispheres, two cerebella and two thalami. There were three orbits two external ears, two noses, fused adjacent maxilla and two oral cavities with two fused oral opening and two jaws. The woman did not consent to any further investigations and the pregnancy was terminated. The postmortem examination confirmed the diagnosis in a male fetus with a crown-rump length of 155 mm, weighing 450 g. The body appeared normal except for a small poorly formed rudiment of a supernumerary digit next to the thumb of the right hand. The ultrasound examination and postmortem finding of this case is described with a short review of the literature. (c) 2007 S. Karger AG, Basel

Ghrelin and the cardiovascular system.

Isgaard, Jörgen

2013-01-01

Although ghrelin was initially associated with regulation of appetite, the cardiovascular system has also been recognized as a potentially important target for its effects. Moreover, experimental and a limited number of clinical studies suggest a potential role for ghrelin in the treatment of congestive heart failure. So far, reported cardiovascular effects of growth hormone secretagogues and/or ghrelin include lowering of peripheral resistance, either direct at the vascular level and/or by modulating sympathetic nervous activity. Other observed effects indicate possible improvement of contractility and cardioprotective and anti-inflammatory effects both in vivo and in vitro. Taken together, these results offer an interesting perspective on the future where further studies aiming at evaluating a role of growth hormone secretagogues and ghrelin in the treatment of cardiovascular disease are warranted.

2012-01-01

Treatment of sick neonates originated in maternity and foundling hospitals in the 19th century. Nosocomial infections and difficult logistics of wet-nursing prevented admission of neonates in most children's hospitals well into the 20th century. In this article, 31 hospitals are described, all located in large cities, in which preterm and sick neonates were treated before the Great Depression. Even though mostly initiated by private charity, these institutions performed research right from the start. Topics included warming and feeding preterm infants, collecting and distributing human milk, developing and storing breast milk substitutes, prevention of rickets and nosocomial infections, maternal and public education regarding infection control, pathoanatomic characterisation of diseases and malformations and epidemiologic studies of infant mortality. These pioneering hospitals, their founding dates, researchers and classic publications are presented in a table. Copyright © 2012 S. Karger AG, Basel.

History of the Buttonhole Technique.

Misra, Madhukar

2015-01-01

The constant side method of access cannulation in hemodialysis, popularly known as the 'buttonhole' method, has an interesting history. Dr. Zbylut J. Twardowski, a Polish nephrologist, discovered this technique by pure serendipity in 1972. A patient with a complicated vascular access history and limited options for cannulation was repeatedly 'stuck' at the same sites by a nurse. Soon it was noticed that the cannulation at the same spot became easier with time. Since the needles were being reused, the sharpness of the needles decreased with time and the bluntness of the needle seemed to minimize the damage to the cannulation tract (another serendipity!). This method soon became popular among patients, and many patients started using this technique. This chapter traces the invention of this technique and its subsequent development following Dr. Twardowski's emigration to the USA. © 2015 S. Karger AG, Basel.

Everything you always wanted to know about sex ... in flies.

'Everything you always wanted to know about sex' is a workshop organized as part of the annual Drosophila Research Conference of the Genetics Society of America. This workshop provides an intellectual venue for interaction among research groups that study sexual dimorphism from the molecular, evolutionary, genomic, and behavioral perspectives. The speakers summarize the key ideas behind their research for people working in other fields, outline unsolved questions, and offer their opinions about future directions. The 2010 workshop highlighted the power of the Drosophila model for understanding sexual dimorphism at levels ranging from cell biology and gene regulation to population genetics and genome evolution, and demonstrated the importance of cross-disciplinary interactions in the study of sex. In this respect, Drosophila sets a good example for research in other organisms, including humans and their mammalian relatives. Copyright © 2010 S. Karger AG, Basel.

Have sex or not? Lessons from bacteria.

PubMed

Lodé, T

2012-01-01

Sex is one of the greatest puzzles in evolutionary biology. A true meiotic process occurs only in eukaryotes, while in bacteria, gene transcription is fragmentary, so asexual reproduction in this case really means clonal reproduction. Sex could stem from a signal that leads to increased reproductive output of all interacting individuals and could be understood as a secondary consequence of primitive metabolic reactions. Meiotic sex evolved in proto-eukaryotes to solve a problem that bacteria did not have, namely a large amount of DNA material, occurring in an archaic step of proto-cell formation and genetic exchanges. Rather than providing selective advantages through reproduction, sex could be thought of as a series of separate events which combines step-by-step some very weak benefits of recombination, meiosis, gametogenesis and syngamy.

Our appreciation and understanding of what is now known as the split cord malformation (SCM) have a long history. The oldest known example of SCM is from roughly AD 100. Other isolated examples can be found in the large body of work of the pathologists of the 1800s, where the SCMs were found incidentally during autopsies. SCM has a rich history and has intrigued physicians for over 200 years. Many well-known figures from the past such as Chiari and von Recklinghausen, both pathologists, made early postmortem descriptions of SCM. With the advent of MRI, these pathological embryological derailments can now often be detected and appreciated early and during life. Our understanding and ability to treat these congenital malformations as well as the terminology used to describe them have changed over the last several decades. © 2016 S. Karger AG, Basel.

Sex Reversal in Amphibians.

PubMed

Flament, Stéphane

2016-01-01

Amphibians have been widely used to study developmental biology due to the fact that embryo development takes place independently of the maternal organism and that observations and experimental approaches are easy. Some amphibians like Xenopus became model organisms in this field. In the first part of this article, the differentiation of the gonads in amphibians and the mechanisms governing this process are reviewed. In the second part, the state of the art about sex reversal, which can be induced by steroid hormones in general and by temperature in some species, is presented. Also information about pollutants found in the environment that could interfere with the development of the amphibian reproductive apparatus or with their reproductive physiology is given. Such compounds could play a part in the amphibian decline, since in the wild, many amphibians are endangered species. © 2016 S. Karger AG, Basel.

Oral Cavity Cancer: Risk Factors, Pathology, and Management.

PubMed

Ernani, Vinicius; Saba, Nabil F

2015-01-01

Oral cavity cancers are predominantly squamous cell carcinomas, which arise from premalignant lesions through a multistep carcinogenesis process. Tobacco and alcohol are the major etiologic factors, although human papillomavirus has also recently been implicated as a causative agent. The possibility of a second primary malignancy should be considered during the diagnostic evaluation of head and neck cancers, as well as during the posttreatment surveillance phase. The goals of treatment are not only to improve survival outcomes but also to preserve organ function. These cancers are generally treated with a combination of surgery, radiation therapy, and chemotherapy. A multidisciplinary approach, involving surgeons, medical oncologists, and radiation oncologists, as well as dentists, dietitians, and rehabilitation therapists, is generally required for optimal treatment planning and management of patients with head and neck cancer. © 2015 S.

2016-01-01

Awake craniotomy is a special method to prevent motor deficits during the resection of lesions that are located in, or close to, functional areas. Although it is more commonly performed in adult patients, reports of pediatric cases undergoing awake craniotomy are limited in the literature. In our clinic, where we frequently use awake craniotomy in adult patients, we performed this method in 2 selected pediatric cases for lesion surgery. At an early age, these 2 cases diagnosed with epilepsy presented cerebral lesions, but since the lesions enclosed functional areas, surgical resection was not regarded as a treatment option at this time. In these 2 pediatric cases, we successfully completed lesion surgery with awake craniotomy. The method and the techniques employed during surgery are presented concomitant with other reports in the literature. © 2016 S. Karger AG, Basel.

Contemporary Trends in Onset and Completion of Puberty, Gain in Height and Adiposity.

PubMed

Biro, Frank M; Kiess, Wieland

2016-01-01

Recent studies have documented earlier pubertal maturation in both girls and boys. Several factors have been proposed to account for earlier maturation. Epidemiologic studies have indicated that genetic factors are the most important influence contributing to the variability in the onset of puberty. Studies have also noted the association of elevated BMI with earlier puberty in girls, although the relationship between BMI and onset of puberty in boys is less consistent. The relationship of BMI and onset of puberty may be mediated by several factors, including leptin and kisspeptin, changes in bioavailable sex hormones, and environmental exposures. Recently, there have been genome-wide meta-analyses examining onset of puberty and anthropometric traits that may provide insight into the relationships of BMI, height velocity, and pubertal timing. Newer fields of investigation include examination of epigenetic modification. © 2016 S. Karger AG, Basel.

'New embryos' - new challenges for the ethics of stem cell research.

PubMed

Holm, Søren

2008-01-01

Among the many ethical issues raised by human embryonic stem cell research (in the following all references to 'stem cells' should be read as references to human embryonic stem cells), two have gained specific prominence: (1) whether stem cell research is ethically problematic because it entails the destruction of human embryos and (2) what kind of control embryo donors should have over the stem cell lines derived from their embryos. In the present paper, I will analyse how these two issues are engaged by various attempts to derive stem cells from anomalous embryos (e.g. embryos in cleavage arrest, embryos not implanted following pre-implantation genetic diagnosis or embryos created by altered nuclear transfer) or in ways that are claimed to be non-destructive for the embryo (e.g. blastocyst or blastomere biopsy).

2010-01-01

Congenital tricuspid valve disease (Ebstein's anomaly, tricuspid valve dysplasia) with severe tricuspid regurgitation and cardiomegaly is associated with poor prognosis. Fetal echocardiography can accurately measure right atrial enlargement, which is associated with a poor prognosis in the fetus with tricuspid valve disease. Fetal lung volumetric assessments have been used in an attempt to predict viability of fetuses using ultrasonogram and prenatal MRI. We describe a fetus with tricuspid dysplasia, severe tricuspid regurgitation, right atrial enlargement and markedly reduced lung volumes. The early gestational onset of cardiomegaly with bilateral lung compression raised the possibility of severe lung hypoplasia with decreased broncho-alveolar development. Use of fetal echocardiography with measurement of pulmonary artery size combined with prenatal MRI scanning of lung volumes resulted in an improved understanding of this anomaly and directed the management strategy towards a successful Fontan circulation. 2010 S.

Bacillus cereus is a gram-positive, spore-forming bacterium possessing an important and historical record as a human-pathogenic bacterium. However, several strains of this species exhibit interesting potential to be used as plant growth-promoting rhizobacteria. Here, we report the draft genome sequence of B. cereus strain CITVM-11.1, which consists of 37 contig sequences, accounting for 5,746,486 bp (with a GC content of 34.8%) and 5,752 predicted protein-coding sequences. Several of them could potentially be involved in plant-bacterium interactions and may contribute to the strong antagonistic activity shown by this strain against the charcoal root rot fungus, Macrophomina phaseolina. This genomic sequence also showed a number of genes that may confer this strain resistance against several polluting heavy metals and for the bioconversion of mycotoxins. © 2018 S. Karger AG, Basel.

Gastro-oesophageal reflux disease symptoms and tooth wear in patients with Sjögren's syndrome.

The aim of this study was to assess the prevalence of gastro-oesophageal reflux disease (GORD) symptoms and tooth wear in patients with Sjögren's syndrome (SS) compared with matched controls. GORD symptoms were assessed for 33 SS patients and 20 age- and sex-matched controls. Tooth wear was assessed in all patients and controls. The results were further analysed in two subgroups of SS patients and controls with and without GORD symptoms (SS patients without GORD symptoms: n = 11, controls without GORD symptoms: n = 18). A higher proportion of SS patients reported suffering from heartburn and regurgitation than controls (p < 0.001 and p = 0.02, respectively). SS patients without GORD symptoms had a statistically significantly higher percentage of surfaces with tooth wear affecting dentine than controls (p < 0.001). Copyright © 2011 S. Karger AG, Basel.

Regulated wet nursing: managed care or organized crime?

PubMed

Obladen, Michael

2012-01-01

Wet nursing was widely practiced from antiquity. For the wealthy, it was a way to overcome the burdens of breastfeeding and increase the number of offspring. For the poor, it was an organized industry ensuring regular payment, and in some parishes the major source of income. The abuse of wet nursing, especially the taking in of several nurslings, prompted legislation which became the basis of public health laws in the second half of the 19th century. The qualifications demanded from a mercenary nurse codified by Soran in the 2nd century CE remained unchanged for 1,700 years. When artificial feeding lost its threat thanks to sewage disposal, improved plumbing, the introduction of rubber teats, cooling facilities and commercial formula, wet nursing declined towards the end of the 19th century.

Gross, Dominik; Tolba, René H

2015-01-01

In recent years, there have been a number of new demands and regulations which have reignited the discussion on ethics in animal-based research. In the light of this development, the present review first presents an overview of underlying core ethical questions and issues. This is followed by an outline of the current discussion on whether animals (used for experimentation) should have rights ascribed to them and whether animals need to have certain characteristics in order to be the beneficiaries of rights. The discourse on concepts of sentience and the 'sociozoological scale' in particular is mapped out in this regard. There follows an outline of relevant ethical positions and current moral approaches to animal-based research (animal rights position, utilitarianism, 'convergence position', intrinsic cultural value of fundamental research, 'contractarianism', anthropocentrism, principle of the three Rs). 2015 S.

To report a 6-year-old boy with post-chicken pox purpura fulminans (PF). A 6-year-old boy presented with purpura of the legs that rapidly progressed to other parts of the limbs and the buttocks. The patient had had chicken pox 10 days prior to presentation. He was afebrile and the chicken pox lesions were dry. He received anti-coagulants, a large volume of fresh frozen plasma, immunoglobulin and steroids. The skin lesions regressed but both hands and parts of the lower limbs remained necrotic; the patient was transferred to an orthopaedic hospital for amputation and skin grafting. This case report shows that PF can occur as a post-infection syndrome after primary varicella. Early and aggressive treatment of post-chicken pox PF might reduce the mortality and morbidity associated with this condition. Copyright 2006 S. Karger AG, Basel.

β-Defensins: multifunctional modulators of infection, inflammation and more?

PubMed

Semple, Fiona; Dorin, Julia R

2012-01-01

Defensins comprise one of the largest groups of host defence peptides, present throughout evolution, in fungi and flowering plants as well as in invertebrates and vertebrates. These cysteine-rich, cationic peptides have a common ability to kill a broad range of microorganisms including bacteria, yeast and viruses. As such, they are a strong component of the arsenal that is an organism's innate immunity. It is becoming increasingly clear, however, that antimicrobial action is only one of the numerous roles of these multifunctional peptides. In recent years, the functions of defensins in immunomodulation have been widely investigated, and their involvement in other processes (such as fertility) is becoming evident. This review addresses recent advances in the immunomodulatory activity of β-defensins as well as the involvement of β-defensins in fertility, development, wound healing and cancer.

Evaluating everyday competence in older adult couples: epidemiological considerations.

Dixon, Roger A

2011-01-01

Among older adults, everyday competence is often expressed in the context of other participating individuals. Although this active human context may be occasionally comprised of mere acquaintances, long-term partners (such as couples) often act as a unit in engaging in everyday actions or reporting on familiar domains. This special section reflects an important movement in aging research to examine couples as an alternative but normatively common unit of analysis. My discussion focuses on 2 main issues. First, I sketch the rationale, logic, expectation and evidence that long-term couples might develop and display unique advantages in everyday competence. Second, I explore the possibilities that epidemiological principles - thus far applied primarily to individual-level aging, decline and disease - may provide concepts or models for research on long-term changes in couple-level adaptation.

Bright light during nighttime: effects on the circadian regulation of alertness and performance.

PubMed

Daurat, A; Foret, J; Benoit, O; Mauco, G

2000-01-01

The present studies evaluated to what extent duration (all-night or 4-hour exposures) and timing of nocturnal bright light (BL) (beginning or end of the night) modulate effects on vigilance. The results showed that all-night BL exposure is able to alleviate the nocturnal decrements in alertness and performance. However, under certain circumstances, this continuous BL exposure may induce adverse effects on mood and finally reveal to be counterproductive. Shorter BL exposure (4 h) during nighttime helps improve mood and performance, although the effects of short BL pulses were less efficacious than all-night BL exposure. The latter part of the night appears the best time for using the alerting effect of BL. The immediate alerting effect of BL seems to be mediated by a global activation of the central nervous system.

The present note provides an overview of the historical development of neurology and its current status in the People's Republic of China, against the backdrop of the current massive transformation of Chinese society. We trace the origins of neurology in China to missionary medicine during the Republican period (1911-1949), and describe how the discipline grows with difficulty throughout the subsequent decades (1950-1976). We then introduce an influential legacy of the post-revolutionary period, the ideal of integrating traditional Chinese medicine (TCM) and Western medicine, and briefly describe recent efforts to modernize medical education and training. Finally, we provide a brief overview of topics in neurology and neuropsychiatry that have a 'Chinese face', last but not least the successful integration of TCM and Western medicine in the treatment of hepatolenticular degeneration/Wilson's disease.

Alvarez, María de Fátima; Medina, Roxana; Pasteris, Sergio E; Strasser de Saad, Ana M; Sesma, Fernando

2004-01-01

Lactobacillus rhamnosus ATCC 7469 was able to grow in glycerol as the sole source of energy in aerobic conditions, producing lactate, acetate, and diacetyl. A biphasic growth was observed in the presence of glucose. In this condition, glycerol consumption began after glucose was exhausted from the culture medium. Glycerol kinase activity was detected in L. rhamnosus ATCC 7469, a characteristic of microorganisms which catabolize glycerol in aerobic conditions. Genetic analysis revealed that this strain possesses two glycerol kinase genes: gykA and glpK, that encode for two different glycerol kinases GykA and GlpK, respectively. The glpK geneis associated in an operon with alpha-glycerophosphate oxidase (glpO) and glycerol facilitator (glpF) genes. Transcriptional analysis revealed that only glpK is expressed when L. rhamnosus was grown on glycerol. Copyright 2004 S. Karger AG, Basel

The Snail Family in Normal and Malignant Haematopoiesis.

PubMed

Carmichael, Catherine L; Haigh, Jody J

2017-01-01

Snail family proteins are key inducers of the epithelial-mesenchymal transition (EMT), a critical process required for normal embryonic development. They have also been strongly implicated in regulating the EMT-like processes required for tumour cell invasion, migration, and metastasis. Whether these proteins also contribute to normal blood cell development, however, remains to be clearly defined. Increasing evidence supports a role for the Snail family in regulating cell survival, migration, and differentiation within the haematopoietic system, as well as potentially an oncogenic role in the malignant transformation of haematopoietic stem cells. This review will provide a broad overview of the Snail family, including key aspects of their involvement in the regulation and development of solid organ cancer, as well as a discussion on our current understanding of Snail family function during normal and malignant haematopoiesis. © 2017 S.

This study, and the companion paper that follows, pays homage to the life and work of Christfried (also Christian or Christofredo) Jakob, a German-born neuropathologist who adopted Argentina as his country of vocation. Rated by von Economo and Koskinas among the three most important pre-1925 cortical neuro-anatomists, alongside Ramón y Cajal, Jakob is little known in the English literature. He has left an impressive record of publications, 30 richly illustrated monographs and 200 articles that span over a vast array of neurological themes, including cortical development and evolution, and the visceral brain. The present paper reviews works from his German years and the first visit to Argentina in 1899-1910.

Family health history (FHH) has potential value in many health care settings. This review discusses the potential uses of FHH information in primary care and the need for tools to be designed accordingly. We developed a framework in which the attributes of FHH tools are mapped against these different purposes. It contains 7 attributes mapped against 5 purposes. In considering different FHH tool purposes, it is apparent that different attributes become more or less important, and that tools for different purposes require different implementation and evaluation strategies. The context in which a tool is used is also relevant to its effectiveness. For FHH tools, it is unlikely that 'one size fits all', although appreciation of different purposes, users and contexts should facilitate the development of different applications from single FHH platforms.

Several different kinds of 'milestone' in the field of blood coagulation are described from the middle decades of the 20th century. Although viewed from the standpoint of clotting per se, attention is also given to implications for innate immunity. The first milestone considered is the protracted saga of clotting dependence on vitamin K, an adventure that spanned more than five decades beginning in the 1920s. The second has to do with the discovery of a half-dozen 'new' clotting factors during the period immediately following World War II. A third pursues a narrower focus and examines the once mysterious transformation of fibrinogen into fibrin. Finally, the clinical treatment of classical hemophilia had a remarkable turning point in the 1960s as the result of simple but sensible measures. © 2015 S. Karger AG, Basel.

2012-01-01

The increasing attention of archaeological and anthropological research towards palaeopathological studies has allowed to focus the examination of many skeletal samples on this aspect and to evaluate the presence of many diseases afflicting ancient populations. This paper describes the most interesting diseases observed in skeletal samples from five necropolises found in urban and suburban areas of Rome during archaeological excavations in the last decades, and dating back to the Imperial Age. The diseases observed were grouped into the following categories: articular diseases, traumas, infections, metabolic or nutritional diseases, congenital diseases and tumors, and some examples are reported for each group. Although extensive epidemiological investigation in ancient skeletal records is impossible, palaeopathology allowed highlighting the spread of numerous illnesses, many of which can be related to the life and health conditions of the Roman population.

Factors That Modulate Neurogenesis: A Top-Down Approach.

LaDage, Lara D

2016-08-24

Although hippocampal neurogenesis in the adult brain has been conserved across the vertebrate lineage, laboratory studies have primarily examined this phenomenon in rodent models. This approach has been successful in elucidating important factors and mechanisms that can modulate rates of hippocampal neurogenesis, including hormones, environmental complexity, learning and memory, motor stimulation, and stress. However, recent studies have found that neurobiological research on neurogenesis in rodents may not easily translate to, or explain, neurogenesis patterns in nonrodent systems, particularly in species examined in the field. This review examines some of the evolutionary and ecological variables that may also modulate neurogenesis patterns. This 'top-down' and more naturalistic approach, which incorporates ecology and natural history, particularly of nonmodel species, may allow for a more comprehensive understanding of the functional significance of neurogenesis. © 2016 S.

2013-01-01

Despite its remarkable barrier function, the skin remains an attractive site for systemic drug delivery given its easy accessibility, large surface area and the possibility to bypass the gastrointestinal tract and the liver and so modify drug absorption kinetics. The pioneering work of Scheuplein, Higuchi and others in the 1960s helped to explain the processes involved in passive percutaneous absorption and led to the development of mathematical models to describe transdermal drug delivery. The intervening years have seen these theories turned to practice and a significant number of transdermal systems are now available including some that employ active drug delivery. This review briefly discusses the evolution of transdermal therapeutic systems over the years and the potential of newer transdermal technologies to deliver hydrophilic drugs and macromolecules through the skin. © 2013 S.

Over 2 million people are affected by intracerebral haemorrhage (ICH) worldwide every year, one third of them dying within 1 month, and many survivors being left with permanent disability. Unlike most other stroke types, the incidence, morbidity and mortality of ICH have not declined over time. No standardised diagnostic workup for the detection of the various underlying causes of ICH currently exists, and the evidence for medical or surgical therapeutic interventions remains limited. A dedicated European research programme for ICH is needed to identify ways to reduce the burden of ICH-related death and disability. The European Research Network on Intracerebral Haemorrhage EURONICH is a multidisciplinary academic research collaboration that has been established to define current research priorities and to conduct large clinical studies on all aspects of ICH.

The management of hair and scalp conditions is difficult in any patient, especially given the emotional and psychological implications of hair loss. This undertaking becomes even more challenging in the ethnic patient. Differences in hair care practices, hair shaft morphology, and follicular architecture add complexity to the task. It is imperative that the physician be knowledgeable about these practices and the phenotypic differences seen in ethnic hair in order to appropriately diagnose and treat these patients. In this chapter, we will discuss cultural practices and morphologic differences and explain how these relate to the specific disorders seen in ethnic populations. We will also review the most prominent of the ethnic hair conditions including acquired trichorrhexis nodosa, traction alopecia, central centrifugal cicatricial alopecia, pseudofolliculitis barbae, dissecting cellulitis, and acne keloidalis nuchae. © 2015 S.

2017-01-01

The pillars of anti-doping are detection, deterrence, and prevention. Detection takes the form of testing for banned substances. Deterrence builds on testing and gathering evidence. Athletes who test positive are exposed to penalties. The main tool of prevention is education. Education takes many forms and can be implemented in many ways. This chapter addresses the nature and challenges of current anti-doping education. Firstly, general goals of education and their connection to sport are discussed. Secondly, three normative interpretations of sport are presented, and their implications for anti-doping education are examined. Instrumentalist interpretations and interpretations with emphasis on performance and enhancement challenge the anti-doping campaign. A human excellence interpretation is advocated in which anti-doping is considered a consistent and integral part of sport. Thirdly, future challenges for anti-doping education are reflected upon. © 2017 S. Karger AG, Basel.

The aim of this study is to investigate psychometric properties of the Client Satisfaction Questionnaire (CSQ-8) in a Dutch substance abuse population. The CSQ-8 and the Mental Health Thermometer (the standard Dutch satisfaction instrument) were sent to 927 patients of a Dutch substance abuse treatment centre. (response rate 28.3%; n = 262). Data were compared on several variables (i.e., age, gender, ethnicity, treatment type). For a subgroup of responders (n = 84), data were compared with pre-treatment problem severity and treatment need (the European Addiction Severity Index). Both internal consistency and concurrent validity were found to be high. Only treatment type had significant effects on CSQ-8 satisfaction scores. Scores were negatively skewed. The CSQ-8 is as suitable an instrument to be used in addict populations, as it is in other populations. (c) 2005 S. Karger AG, Basel

Several chemicals inhibit the accumulation of abnormal prion proteins in vitro. We administered one, the antimalarial agent quinacrine, to three patients with sporadic Creutzfeldt-Jakob disease (CJD) and to one with iatrogenic CJD. Quinacrine at 300 mg/day was given enterally for 3 months. Within 2 weeks of administration, the arousal level of the patient with akinetic mutism improved. The other 3 patients, insensible before treatment, had integrative responses such as eye contact or voluntary movement in response to verbal and/or visual stimuli restored. Clinical improvement was transient, lasting 1-2 months during treatment. Quinacrine was well tolerated, except for liver dysfunction and yellowish pigmentation. Although its antiprion activity in the human brain has yet to be proved, these modest effects of quinacrine suggest the possibility of using chemical intervention against prion diseases.

2018-06-08

Stroke and hepatic vein thrombosis are highly associated with neoplasia but are extremely rare events in young, pregnant women. Rare and recurrent thrombotic events in pregnancy increase the suspicion for occult malignancy. We describe the case of a healthy 31-year-old G2P1 who presented with visual changes and dysarthria during pregnancy. Imaging showed cerebral infarcts. Her thrombophilia evaluation was negative. During delivery, she was diagnosed with fulminant Budd-Chiari Syndrome. Hepatic ultrasound suggested malignancy or metastasis, and postpartum CT scan and biopsy confirmed the diagnosis of Stage IV pancreatic cancer. Although rare in pregnancy, a new diagnosis of malignancy should be considered in patients with recurrent unexplained hypercoagulable complications. We propose an evidence-based algorithm for evaluation of occult malignancy in pregnancy based upon this case and review of the literature. © 2018 S. Karger AG, Basel.

We investigated the relationship between sleep disturbance and cognitive decline or clinical conversion in individuals with normal cognition (CN), as well as those with mild cognitive impairment (MCI) and dementia due to Alzheimer disease (AD-dementia). Secondary analysis of 1,629 adults between 48 and 91 years of age with up to 24 months of follow-up from the ADNI (Alzheimer's Disease Neuroimaging Initiative), a longitudinal cohort study. Sleep disturbance was not associated with decline in memory, executive function, or global cognition. The presence of sleep disturbance did not significantly increase the risk of diagnostic conversion in CN, early MCI, or late MCI participants. This study investigated the effect of sleep disturbance on cognitive decline using several outcomes and does not support the hypothesis that sleep disturbance predicts subsequent cognitive decline. © 2018 S.

Making sense of differing overdose mortality: contributions to improved understanding of European patterns.

PubMed

Waal, Helge; Gossop, Michael

2014-01-01

The European Monitoring Centre for Drugs and Drug Addiction, EMCDDA, publishes statistics for overdose deaths giving a European mean number, and ranking nations in a national 'league table' for overdose deaths. The interpretation of differing national levels of mortality is more problematic and more complex than is usually recognised. Different systems are used to compile mortality data and this causes problems for cross-national comparisons. Addiction behaviour can only be properly understood within its specific social and environmental ecology. Risk factors for overdose, such as the type of drug consumed, and the route of administration, are known to differ across countries. This paper describes problems associated with ranking and suggests how mortality data might be used in high-level countries aiming at reduction in the number of overdose deaths. Copyright © 2013 S.

The respiratory tract is faced daily with 10,000 L of inhaled air. While the majority of air contains harmless environmental components, the pulmonary immune system also has to cope with harmful microbial or sterile threats and react rapidly to protect the host at this intimate barrier zone. The airways are endowed with a broad armamentarium of cellular and humoral host defense mechanisms, most of which belong to the innate arm of the immune system. The complex interplay between resident and infiltrating immune cells and secreted innate immune proteins shapes the outcome of host-pathogen, host-allergen, and host-particle interactions within the mucosal airway compartment. Here, we summarize and discuss recent findings on pulmonary innate immunity and highlight key pathways relevant for biomarker and therapeutic targeting strategies for acute and chronic diseases of the respiratory tract. © 2018 S.

We found and characterized two cry8 genes from the Bacillus thuringiensis strain INTA Fr7-4 isolated in Argentina. These genes, cry8Kb3 and cry8Pa3, are located in a tandem array within a 13,200-bp DNA segment sequenced from a preparation of total DNA. They encode 1,169- and 1,176-amino-acid proteins, respectively. Both genes were cloned with their promoter sequences and the proteins were expressed separately in an acrystalliferous strain of B. thuringiensis leading to the formation of ovoid crystals in the recombinant strains. The toxicity against larvae of Anthonomus grandis Bh. (Coleoptera: Curculionidae) of a spore-crystal suspension from the recombinant strain containing cry8Pa3 was similar to that of the parent strain INTA Fr7-4. © 2014 S. Karger AG, Basel.

The aim of this study was to evaluate possible interactions between childhood trauma, temperament, character, and psychopathology among alcohol-dependent men. Participants were 156 alcohol-dependent men consecutively admitted to a dependency treatment unit. The Childhood Abuse and Neglect Questionnaire, the Temperament and Character Inventory, and the Symptom Checklist-Revised were administered to all participants. Childhood abuse and neglect did not have any effect on temperament and character scores in multivariate analysis. Whereas childhood abuse had a significant main effect on all types of clinical psychopathology except depression and psychoticism scores, childhood neglect only had a significant main effect on depression scores. There was no interaction between childhood abuse and neglect on these analyses. Among alcohol-dependent men, childhood abuse and neglect contribute to general psychopathology through distinct clinical consequences, independently of temperamental and characterological features.

The central role of renal microcirculatory dysfunction in the pathogenesis of acute kidney injury.

PubMed

Ince, Can

2014-01-01

Acute kidney injury (AKI) is a rapidly developing condition often associated with critical illness, with a high degree of morbidity and mortality, whose pathophysiology is ill understood. Recent investigations have identified the dysfunction of the renal microcirculation and its cellular and subcellular constituents as being central to the etiology of AKI. Injury is caused by inflammatory activation involving endothelial leucocyte interactions in combination with dysregulation of the homeostatis between oxygen, nitric oxide, and reactive oxygen species. Effective therapies expected to resolve AKI will have to control inflammation and restore this homeostasis. In order to apply and guide these therapies effectively, diagnostic tools aimed at physiological biomarkers of AKI for monitoring renal microcirculatory function in advance of changes in pharmacological biomarkers associated with structural damage of the kidney will need to be developed. 2014 S.

In a girl presenting with features of Wolf-Hirschhorn syndrome, cytogenetic and molecular cytogenetic analysis revealed a rearranged chromosome 4 with monosomy of the distal bands 4pter-->4p16.2 and trisomy of the distal bands 4q35.1-->4qter [rec dup(4q)] due to a large, paternal pericentric inversion. In the following two pregnancies, prenatal diagnosis showed the same imbalance in one fetus and a reverse segmental imbalance [rec dup(4p)] in the other. We discuss the recombination risk of the given inversion with respect to the size of the inverted segment and the viability of the recombinants. The high frequency of recombinants in this family and others suggests a high recurrence risk in similar cases with large pericentric inversions comprising almost entire chromosomes. Copyright 2001 S.

Phosphate toxicity and vascular mineralization.

PubMed

Razzaque, Mohammed S

2013-01-01

Vascular calcification or mineralization is a major complication seen in patients with advanced stages of chronic kidney disease (CKD), and it is associated with markedly increased morbidity and mortality. Most of the CKD-related vascular mineralization is attributable to abnormal mineral ion metabolism. Elevated serum calcium and phosphate levels, along with increased calcium-phosphorus byproduct, and the use of active vitamin D metabolites are thought to be the predisposing factors for developing vascular mineralization in patients with CKD. Recent experimental studies have shown that vascular mineralization can be suppressed by reducing serum phosphate levels, even in the presence of extremely high serum calcium and 1,25-dihydroxyvitamin D levels, indicating that reducing 'phosphate toxicity' should be the important therapeutic priority in CKD patients for minimizing the risk of developing vascular mineralization and the disease progression.

Regulatory environment and claims - limits and opportunities.

PubMed

Martin, Ambroise

2010-01-01

During the past decade, the use of claims became more and more important in many countries in relation to the increased awareness of consumer about the link between foods and health, offering to industry a valuable opportunity to differentiate and valorize their products and to promote innovation. However, more and more stringent regulations are developed, all based on the general principles adopted by the Codex Alimentarius Commission. In addition to the different regulatory processes and administrative requirements according to the country, the high level (and cost) of scientific substantiation of claims, the constraints introduced by nutrient profiles and the poor knowledge of the impact on consumer depending on the cultural contexts may limit these opportunities or, at least complicate their use. All these issues are briefly analyzed, highlighting some striking convergences and differences between countries. Copyright © 2010 S. Karger AG, Basel.

Evaluation of the norrie disease gene in a family with incontinentia pigmenti.

PubMed

Shastry, B S; Trese, M T

2000-01-01

Incontinentia pigmenti (IP) is an ectodermal multisystem disorder which can affect dental, ocular, cardiac and neurologic structures. The ocular changes of IP can have a very similar appearance to the retinal detachment of X-linked familial exudative vitreoretinopathy, which has been shown to be caused by the mutations in the Norrie disease gene. Therefore, it is of interest to determine whether similar mutations in the gene can account for the retinal pathology in patients with IP. To test our hypothesis, we have analyzed the entire Norrie disease gene for a family with IP, by single strand conformational polymorphism followed by DNA sequencing. The sequencing data revealed no disease-specific sequence alterations. These data suggest that ocular findings of IP are perhaps associated with different genes and there is no direct relationship between the genotype and phenotype. Copyright 2000 S. Karger AG, Basel

What Really Rigs Up RIG-I?

PubMed

Barik, Sailen

2016-01-01

RIG-I (retinoic acid-inducible gene 1) is an archetypal member of the cytoplasmic DEAD-box dsRNA helicase family (RIG-I-like receptors or RLRs), the members of which play essential roles in the innate immune response of the metazoan cell. RIG-I functions as a pattern recognition receptor that detects nonself RNA as a pathogen-associated molecular pattern (PAMP). However, the exact molecular nature of the viral RNAs that act as a RIG-I ligand has remained a mystery and a matter of debate. In this article, we offer a critical review of the actual viral RNAs that act as PAMPs to activate RIG-I, as seen from the perspective of a virologist, including a recent report that the viral Leader-read-through transcript is a novel and effective RIG-I ligand. © 2016 S.

P1,P4-diadenosine tetraphosphate (Ap4A) is a vasoactive dinucleotide possessing natriuretic activity. It is unclear, however, which part of the nephron is the target site of action for Ap4A. We evaluated the tubular sites of Ap4A action using the lithium clearance technique. Ap4A at a priming dose of 2 micromol/kg with subsequent infusion at 20 nmol/kg/min increased fractional water and sodium excretion 2.5- and 5.6-fold, respectively. Moreover, Ap4A increased lithium clearance 1.9-fold and fractional lithium excretion 2.8-fold. Fractional water and sodium excretion from distal nephron segments was not significantly affected by Ap4A. These results suggest that Ap4A induces natriuresis mainly through inhibition of proximal tubular reabsorption of sodium. Copyright 2007 S. Karger AG, Basel.

To evaluate how concentration and pH of TiF(4) influence the erosion-protective effect. Specimens were treated with a TiF(4) solution: (1) 0.5 M F, pH 1.2, (2) 0.05 M F, pH 2.1, (3) 0.5 M F, pH 2.1, or (4) 0.05 M F, pH 1.2; then, they were exposed to HCl. After 2 min, the proportions of the area covered with the coating were 93, 71, 17 and 0% in groups 1-4. When present, the coating seemed to protect the surface. After 6 min, a coating could only be seen in group 1 (43%). Reducing the concentration of TiF(4) and increasing the pH of the solution decreased the protective effect. 2011 S. Karger AG, Basel.

Serum Creatinine: Not So Simple!

2017-01-01

Measuring serum creatinine is cheap and commonly done in daily practice. However, interpretation of serum creatinine results is not always easy. In this review, we will briefly remind the physiological limitations of serum creatinine due notably to its tubular secretion and the influence of muscular mass or protein intake on its concentration. We mainly focus on the analytical limitations of serum creatinine, insisting on important concept such as reference intervals, standardization (and IDMS traceability), analytical interferences, analytical coefficient of variation (CV), biological CV and critical difference. Because the relationship between serum creatinine and glomerular filtration rate is hyperbolic, all these CVs will impact not only the precision of serum creatinine but still more the precision of different creatinine-based equations, especially in low or normal-low creatinine levels (or high or normal-high glomerular filtration rate range). © 2017 S.

Brall, Caroline; Schröder-Bäck, Peter

In the aftermath of the economic crisis that started in 2008, resources have become scarcer than ever in some countries, also in health care. Priority setting and rationalisation of existing resources also affect pharmaceutical innovations, including those that would contribute to what is called personalised medicine. In this paper, we will highlight the ethical issues surrounding rationalisation and its impact on personalised medicine through the lens of the capability approach. Thereby, challenges to and opportunities for personalised medicine will be examined, assessing how they affect patients' 'real options' to access innovative therapies. In our focus on the 'first challenge: citizens and patients' of the so-called Strategic Research and Innovation Agenda, the strength of the capability approach becomes particularly apparent in identifying what different values are at stake in this context. © 2016 S.

Polyamines are unbiquitous, naturally occurring small aliphatic, polycationic, endogenous compounds. They are involved in many cellular processes and may serve as secondary or tertiary messengers to hormonal regulation. The relationship of polyamines and skeletal muscle mass of adductor longus, extensor digitorum longus, and gastrocnemius under unloading (hindlimb suspension) conditions was investigated. Unloading significantly affected skeletal muscle polyamine levels in a fiber-type-specific fashion. Under loading conditions, clenbuterol treatment increased all polyamine levels, whereas under unloading conditions, only the spermidine levels were consistently increased. Unloading attenuated the anabolic effects of clenbuterol in predominately slow-twitch muscles (adductor longus), but had little impact on clenbuterol's action as a countermeasure in fast- twitch muscles such as the extensor digitorum longus. Spermidine appeared to be the primary polyamine involved in skeletal muscle atrophy/hypertrophy. Copyright 2002 S. Karger AG, Basel.

In the presentation, she included a summary of 30 years of work already accomplished, the present state of the art, and musings about issues encountered, potential resolutions, progress that needed to be made, and her perception of how the field needed to evolve in order to become ultimately successful as a clinical service. This commentary looks back 34 years, with observations about Dr. Bibbo's predictions and how the field of cytology automation did actually evolve in the decades following her address.

Turner syndrome is a chromosomal disorder usually caused by complete deletion of an X chromosome, with deletion in the short arm of the X chromosome being a rare cause of the condition. Patients with Turner syndrome commonly develop hypertension, and associated vascular complications such as aortic dissection or cerebral hemorrhage have been reported. Cerebral hemorrhage in Turner syndrome is a rare complication, and only a few reports have been published. In these reports, all patients have XO karyotypes or a mosaic type as the cause of Turner syndrome, while no other Turner syndrome types have been documented. In this report, we present for the first time a patient with Turner syndrome caused by deletion in the short arm of the X chromosome who experienced hypertensive hemorrhage as a late complication. © 2017 S.

Pavlov's Reflex before Pavlov: Early Accounts from the English, French and German Classic Literature.

The concept of classical conditioning (CC), strongly connected with the name and work of the Russian physiologist Ivan Petrovich Pavlov (1849-1936), has become the foundation of the modern science of learning and, in particular, of the influential theories of Watson and Skinner and the entire school of behaviourism. In this paper, we give a number of forgotten accounts of CC in the English, French, and German classic literature that pre-date Pavlov's reports by decades or even centuries. These instances are taken from works of the 16th, 18th, and 19th centuries - authored by some of the finest writers of England (Sterne, Locke), France (Rabelais), and Germany (Jean Paul) - and indicate that the psychological mechanisms now described as CC were known long before Pavlov and his successors elaborated on them in a systematic way. © 2017 S.

This study describes a unique case of bilateral stress fractures of the fibulae and provides a literature review. A 16-year-old female badminton player presented with pain around the bilateral distal lateral legs. She had mild bilateral varus deformity at the knee joint, and the bilateral ankles showed valgus deformity in standing posture. Radiographs and computed tomography showed periosteal reactions on the bilateral distal fibulae. Technetium-99m bone scintigraphy demonstrated increased uptake in the bilateral distal fibulae and the bilateral middle third of the tibiae. A diagnosis of bilateral distal fibular stress fractures was made. She was advised to stop playing badminton until the symptoms disappeared. Varus deformity of the knee and valgus deformity of the ankle may have influenced the mechanism underlying bilateral symmetric stress fractures. Copyright © 2010 S. Karger AG, Basel.

To study face and emotion recognition in children with mostly expressive specific language impairment (SLI-E). A test movie to study perception and recognition of faces and mimic-gestural expression was applied to 24 children diagnosed as suffering from SLI-E and an age-matched control group of normally developing children. Compared to a normal control group, the SLI-E children scored significantly worse in both the face and expression recognition tasks with a preponderant effect on emotion recognition. The performance of the SLI-E group could not be explained by reduced attention during the test session. We conclude that SLI-E is associated with a deficiency in decoding non-verbal emotional facial and gestural information, which might lead to profound and persistent problems in social interaction and development.

Drug-induced hypersensitivity syndrome (DIHS) is a severe form of drug eruptions associated with viral reactivations. Autoimmune diseases have been reported to develop several months or years after the resolution of DIHS. We describe a 36-year-old man with cervical lymphadenopathy and an erythematous eruption affecting the face and neck, which evolved into clinically evident systemic lupus erythematosus. He had had an episode of DIHS 4 years previously, in which human herpesvirus-6 and Epstein-Barr virus (EBV) were reactivated. Expression of EBV-encoded RNA was detected in the lymph node. On the basis of findings in this patient, we suggest that EBV is pathogenically important in the sequence of events leading to the onset of systemic lupus erythematosus and that patients with a history of DIHS may be at a risk of eventually developing autoimmune diseases. 2008 S.

Atherosclerosis affects all vascular beds, including the coronary, carotid, intracerebral, peripheral and aortic vascular beds, and is responsible for tremendous morbidity and mortality, with the most serious outcomes being myocardial infarction, stroke and death. Historically the effects of vascular narrowing and associated thrombosis have been key indicators of disease in the coronary and carotid territories, with degrees of vascular stenosis being of profound importance in carotid surgery trials. Our improving understanding of the biology of atheromatous lesions and the development of alternative therapeutic agents which can initiate actual plaque regression have created a need to attempt to image plaque itself, with the carotid artery being an achievable target. This article reviews current strategies for assessing carotid atherosclerotic disease, particularly with reference to identifying plaque components and risk of rupture, the so-called vulnerable plaque.

To clarify the pathogenesis of transient hyper-17alpha-hydroxyprogesteronemia, we initiated a laboratory investigation in a pre-term infant with persistently high serum 17alpha-hydroxyprogesterone (17-OHP) until 2 months of age. Serum 17-OHP level was measured by high-performance liquid chromatography and radioimmunoassay, and gene analysis of CYP21A2 (21-hydroxylase) was performed. Serum 17-OHP level on the 29th day of life was 25.4 ng/ml, and the urinary steroid profile showed low pregnanetriolone. Gene analysis of 21-hydroxylase disclosed no mutation, and 17-OHP normalized by 3 months of age without specific treatment. Transient elevations in 17-OHP, which do not appear related to cross-reactions with products of a residual fetal adrenal cortex, may occur in the first few months of life. Copyright 2004 S.

alpha-Synuclein has been isolated as a component of amyloid in addition to the major A beta peptide in Alzheimer disease (AD). However, there are conflicting reports regarding the association of alpha-synuclein gene polymorphism with AD. Using a novel and common polymorphism in intron 3, we examined the relationship between AD and alpha-synuclein and apolipoprotein E (ApoE) genes in 183 Japanese AD patients and 210 controls. Carriers of the alpha-synuclein deletion (D) allele had a 2.2-fold increased risk of developing AD than noncarriers in women. The odds ratio for the ApoE epsilon 4 and the alpha-synuclein D allele was 11.4 in women. The results showed that the alpha-synuclein gene is associated with sporadic AD in women, independent of ApoE epsilon 4 status. Copyright 2001 S. Karger AG, Basel

To mark key developments in research ethics, we will distinguish between what we call research ethics 1.0 and research ethics 2.0. Whereas research ethics 1.0 focuses on individual integrity and informed consent, research ethics 2.0 entails social scientific integrity within a broader perspective of a research network.

The effect of the moon on human reproduction has been scarcely investigated and with controversial results. The present analysis describes a significant effect of extreme perigeal lunar positions on the number of hospitalized spontaneous abortions (n = 1,329) recorded at two university clinics and a public hospital at Padova, Italy, during the years 2000-2003. Spectral analysis evidenced a 205-day period which appears to be correlated with the 206-day periodicity in extreme lunar distances. Circa-septan and circa-annual periodicities were also observed. Peak significances were determined by a Monte Carlo approach (circa-septan and 205-day periodicities: p < 0.001; circa-annual periodicity: p < 0.05). Our study indicates that the occurrence of human abortions displays suggestive periodicities that may be of relevance for gynecological and obstetrical practice. Copyright (c) 2004 S.

2016-01-01

In cardiac magnetic resonance imaging, hyperenhancement of the pericardium post gadolinium administration in acute chest pain often signifies pericarditis with an acute inflammatory response and neovascularization. In the context of constrictive pericarditis, case series have indicated that the intensity of hyperenhancement and the thickness of the pericardium imply reversibility of the physiology of the constrictive pericarditis. We present a case of intense hyperenhancement and marked thickening of the pericardium in a patient with constrictive pericarditis with antecedent chest pain. Surgical resection of the pericardium and microscopy revealed a chronic fibrotic state with no evidence of inflammation or neovascularization, thus clarifying the failure of initial medical/anti-inflammatory treatment. Our case highlights the fact that hyperenhancement of the pericardium post gadolinium is non-specific for histology and does not necessarily imply the reversibility of pericardial constriction. © 2016 S.

The aim of this study was to analyse the role of family and partnership in remission from alcohol dependence in treated (n = 50) and untreated (n = 115) individuals. Standardised questionnaires to assess social support, social pressure, coping behaviour, and self-efficacy to stay remitted were used. In both media-solicited samples, social support increased from the pre- to the post-resolution period and was stated as an important resolution maintenance factor. Remitters with formal help experienced more partnership conflicts prior to remission and tended to experience more social pressure from their partner. Social support and social pressure from the family and partner were related to an increase in cognitive coping, as hypothesised, however, only in remitters without formal help, whereas an inverse relationship was found in formal help seekers. Implications for alcohol-related interventions are discussed. Copyright 2002 S. Karger AG, Basel

2002-01-01

We report a 50-year-old male patient with a 15-year history of psoriasis including mutilating psoriatic arthritis, in whom the withdrawal of cyclosporin A induced a generalised pustular exacerbation and a aggravation of the joint condition. Two weekly injections of 25 mg of the tumour necrosis factor alpha inhibitor etanercept led to a rapid improvement of his psoriatic arthritis, as well as regression of the pustular eruption, while residual erythema was still present. The clinical response was reflected by an increase in circulating interleukin (IL) 10 and a decrease in IL-6 and IL-8 serum levels during treatment. We conclude that etanercept may be a safe and effective therapy not only in severe psoriatic arthritis, but also in cases of pustular rebound after withdrawal of immunosuppressive agents.

The use of lasers and IPL is a common procedure used by dermatologists and even other professions for the treatment of cosmetically troubling skin conditions. The main advantage of such treatment is a reduction of surgical scars, thus producing a favorable cosmetic outcome, but a major limitation is that histopathologic diagnosis is not usually obtained prior to treatment. Such devices should be carefully used in patients with potentially dangerous melanocytic lesions. We also review the recent literature regarding inadequate treatment of melanocytic lesions with lasers. Copyright © 2012 S. Karger AG, Basel.

Sleep spindles have different properties in different localizations in the cortex. First main objective was to develop an amplitude-independent multi-channel spindle detection method. Secondly the method was applied to study the anteroposterior frequency differences of pure synchronous (visible bilaterally, either frontopolarly or centrally) and diffuse (visible bilaterally both frontopolarly and centrally) sleep spindles. A previously presented spindle detector based on the fuzzy reasoning principle and a level detector were combined to form a multi-channel spindle detector. The spindle detector had a 76.17% true positive rate and 0.93% false-positive rate. Pure central spindles were faster and pure frontal spindles were slower than diffuse spindles measured simultaneously from both locations. The study of frequency relations of spindles might give new information about thalamocortical sleep spindle generating mechanisms. Copyright (c) 2005 S. Karger AG, Basel.

Neodymium-YAG laser core through urethrotomy in obliterative posttraumatic urethral strictures after failed initial urethroplasty.

2002-01-01

To assess the feasibility, problems and results of Nd-YAG laser core through urethrotomy in the management of failed urethroplasty for posttraumatic bulbomembranous urethral strictures. 61 patients with obliterative posttraumatic urethral strictures were treated by Nd-YAG laser core through urethrotomy between May 1997 to April 2000. Of these, 5 patients had failed end-to-end urethroplasty done as an initial procedure at various periods of time. The procedure was performed as day care and patients were discharged within 6 h of procedure. At 24-30 months of follow-up, all patients are voiding well and are continent. Auxiliary procedures were required in 2 cases. Nd-YAG laser core through urethrotomy is a feasible day care option for patients of obliterative urethral strictures following failed initial urethroplasty with successful outcome. Copyright 2002 S.

Cai, Da-Sheng; Zhou, Heng; Liu, Wei-Wei; Pei, Ling

2013-01-01

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a serious health problem, and an effective treatment is needed for use in the clinical setting. In this study, we first constructed ALI models in Adult Sprague-Dawley rats. We then used an herbal medicine, Houttuynia cordata (HC), to enhance the effect of endothelial progenitor cells (EPCs) on ALI. (1) HC improved the therapeutic effects of EPCs on lipopolysachharide-induced ALI in the rat model; (2) HC down-regulated the anti-inflammatory response by suppressing inflammatory cytokines; (3) the combination of EPC and HC reduced expression of iNOS and ET-1 and subsequently prevented lung injury. Combined EPC and HC therapy was more effective than either therapy alone. EPC and HC could be used in the clinical treatment of ALI. © 2013 S. Karger AG, Basel.

2015-01-01

A consensus on the diagnostic criteria for sarcopenia, a common syndrome in the elderly, has not been reached yet. Prevalence rates vary between studies due to the use of different criteria encompassing different measures, correction factors and cutoff points. This study compared prevalence rates of sarcopenia using nine sets of diagnostic criteria applied in two different elderly populations. The study population encompassed 308 healthy elderly participants (152 males, 156 females; mean age 74 years) and 123 geriatric outpatients (54 males, 69 females; mean age 81 years). Diagnostic criteria included relative muscle mass, absolute muscle mass, muscle strength and physical performance. Prevalence rates of sarcopenia varied between 0 and 15% in healthy elderly participants and between 2 and 34% in geriatric outpatients. This study clearly demonstrates the dependency of sarcopenia prevalence rates on the applied diagnostic criteria. © 2015 S. Karger AG, Basel.

Stem cells for the prevention of neonatal lung disease.

O'Reilly, Megan; Thébaud, Bernard

2015-01-01

Preterm birth affects approximately 11% of all newborns worldwide and is a major risk factor for infant mortality and morbidity. A common complication of preterm birth is the chronic lung disease of prematurity called bronchopulmonary dysplasia (BPD). Due to the lack of a specific treatment for BPD, preterm infants surviving with BPD face a lifelong risk of poor lung health. The therapeutic potential of stem cells in regenerative medicine is being harnessed for many diseases, including BPD. Compelling preclinical data using stem cells to prevent/repair lung damage in animal models of experimental BPD has built the basis for its translation into the clinic in preterm infants. This review highlights the exciting translation from bench to bedside that will hopefully lead in the near future to improved pulmonary outcomes in preterm infants. © 2015 S. Karger AG, Basel.

Bilateral asymmetry of humeral torsion and length in African apes and humans.

PubMed

Barros, Anna; Soligo, Christophe

2013-01-01

Few studies have directly compared human and African ape upper limb skeletal asymmetries despite the potential such comparisons have for understanding the origins of functional lateralization in humans and non-human primates. Here, we report the magnitude and direction of asymmetries in humeral torsion and humeral length in paired humeri of 40 Gorilla gorilla, 40 Pan troglodytes and 40 Homo sapiens. We test whether absolute and directional asymmetries differ between measurements, species and sexes. Our results show that humans are unique in being lateralized to the right for both measurements, consistent with human population-level handedness patterns, while apes show no significant directionality at the species level in either measurement. However, absolute torsion asymmetries in apes occur in the same magnitude as in humans, suggesting the existence of functional lateralization at the individual level. Copyright © 2013 S.

Basic mechanisms in intracranial large-artery atherosclerosis: advances and challenges.

PubMed

Arenillas, Juan F; Alvarez-Sabín, José

2005-01-01

Intracranial large-artery atherosclerosis is a major cause of ischemic stroke worldwide. Patients affected by this disease are at a high risk of suffering recurrent ischemic events despite antithrombotic therapy. Progression and a greater extent of intracranial atherosclerosis imply a higher risk for recurrence. Studies performed by our group in patients with symptomatic intracranial large-artery atherosclerosis have shown that: (1) C-reactive protein predicts its progression and recurrence, suggesting that inflammation may play a deleterious role in this condition; (2) a high level of the anti-angiogenic endostatin is also associated with a progressive and recurrent intracranial atherosclerosis, which might support a beneficial role for angiogenesis in this group of patients; and (3) elevated lipoprotein(a) concentration and diabetes mellitus characterize those patients with a higher number of intracranial stenoses. 2005 S.

Italian operas can provide relevant information on the medical knowledge during the Romantic Age, especially in the field of neuroscience. One of the most renowned operas, "Nabucco" by Giuseppe Verdi (1813-1901) may provide us with some information on the state of knowledge on neuropsychiatric diseases in the first part of the nineteenth century. The main character of this opera, the Assyrian king Nabucco suffers from delirium. Psychic signs and symptoms attributed to Nabucco in Verdi's opera could have been influenced by a better knowledge of neuropsychiatric diseases in the nineteenth century. Furthermore, the representation of Nabucco's mental illness in the opera could also have been influenced by direct experiences of Verdi himself, who seems to have suffered from recurrent depressive episodes in that period, and for the rest of his life. © 2017 S.

Radiation hybrid mapping has emerged in the end of the 1990 s as a successful and complementary approach to map genomes, essentially because of its ability to bridge the gaps between genetic and clone-based physical maps, but also using comparative mapping approaches, between 'gene-rich' and 'gene-poor' maps. Since its early development in human, radiation hybrid mapping played a pivotal role in the process of mapping animal genomes, especially mammalian ones. We review here all the different steps involved in radiation hybrid mapping from the constitution of panels to the construction of maps. A description of its contribution to whole genome maps with a special emphasis on domestic animals will also be presented. Finally, current applications of radiation hybrid mapping in the context of whole genome assemblies will be described. (c) 2009 S. Karger AG, Basel.

Dynamic Amygdala Influences on the Fronto-Striatal Brain Mechanisms Involved in Self-Control of Impulsive Desires.

PubMed

Krämer, Bernd; Gruber, Oliver

2015-01-01

Human decisions are guided by a variety of motivational factors, such as immediate rewards, long-term goals, and emotions. We used functional magnetic resonance imaging to investigate the dynamic functional interactions between the amygdala, the nucleus accumbens, and the prefrontal cortex that underlie the influences of emotions, desires, and rationality on human decisions. We found that increased functional connectivity between the amygdala and the nucleus accumbens facilitated the approach of an immediate reward in the presence of emotional information. Further, increased functional interactions of the anteroventral prefrontal cortex with the amygdala and the nucleus accumbens were associated with rational decisions in dilemma situations. These findings support previous animal studies by demonstrating that emotional signals from the amygdala and goal-oriented information from prefrontal cortices interface in the nucleus accumbens to guide human decisions and reward-directed actions. © 2015 S.

2000-01-01

Hepatitis B virus (HBV) DNA has been detected in the sera of hepatitis patients who are negative for hepatitis B surface antigen (HBsAg) by polymerase chain reaction (PCR). The purpose of the present study was to clarify the clinical characteristics of patients with chronic hepatitis C who are negative for serum HBsAg and positive for HBV DNA. The subjects included 49 patients with chronic hepatitis C who were negative for serum HBsAg and 119 blood donors who served as healthy controls. Serum samples were tested for the presence of HBV DNA by the nested PCR method. Serum HBV DNA was detected in 18 (37.7%) of the 49 chronic hepatitis C patients and in none (0%) of the 119 blood donors. Among the hepatitis C patients, HBV DNA was detected in 20.7% of those who were negative for all HBV-associated markers and in 57.1% of those who were positive for one or more HBV-associated marker. The HBV DNA-positive rate among those in each F stage did not significantly differ. The liver function parameters of the HBV DNA-positive and the HBV DNA-negative chronic hepatitis C patients did not significantly differ. These results suggest that hepatitis C virus is frequently coinfected with serum HBsAg-negative HBV, and that the incidence of HBV infection in blood donors is low. However, it is considered that HBsAg-negative HBV infection does not modify the blood biochemical features of chronic hepatitis C. Copyright 2000 S. Karger AG, Basel

Controversy surrounds the questions whether co-occurring depression has negative effects on cognitive-behavioral therapy (CBT) outcomes in patients with panic disorder (PD) and agoraphobia (AG) and whether treatment for PD and AG (PD/AG) also reduces depressive symptomatology. Post-hoc analyses of randomized clinical trial data of 369 outpatients with primary PD/AG (DSM-IV-TR criteria) treated with a 12-session manualized CBT (n = 301) and a waitlist control group (n = 68). Patients with comorbid depression (DSM-IV-TR major depression, dysthymia, or both: 43.2% CBT, 42.7% controls) were compared to patients without depression regarding anxiety and depression outcomes (Clinical Global Impression Scale [CGI], Hamilton Anxiety Rating Scale [HAM-A], number of panic attacks, Mobility Inventory [MI], Panic and Agoraphobia Scale, Beck Depression Inventory) at post-treatment and follow-up (categorical). Further, the role of severity of depressive symptoms on anxiety/depression outcome measures was examined (dimensional). Comorbid depression did not have a significant overall effect on anxiety outcomes at post-treatment and follow-up, except for slightly diminished post-treatment effect sizes for clinician-rated CGI (p = 0.03) and HAM-A (p = 0.008) when adjusting for baseline anxiety severity. In the dimensional model, higher baseline depression scores were associated with lower effect sizes at post-treatment (except for MI), but not at follow-up (except for HAM-A). Depressive symptoms improved irrespective of the presence of depression. Exposure-based CBT for primary PD/AG effectively reduces anxiety and depressive symptoms, irrespective of comorbid depression or depressive symptomatology. Copyright © 2012 S. Karger AG, Basel.

AgPO2F2 and Ag9(PO2F2)14: the first Ag(i) and Ag(i)/Ag(ii) difluorophosphates with complex crystal structures.

The reaction of AgF2 with P2O3F4 yields a mixed valence Ag(I)/Ag(II) difluorophosphate salt with AgAg(PO2F2)14 stoichiometry - the first Ag(ii)-PO2F2 system known. This highly moisture sensitive brown solid is thermally stable up to 120 °C, which points at further feasible extension of the chemistry of Ag(ii)-PO2F2 systems. The crystal structure shows a very complex bonding pattern, comprising of polymeric Ag(PO2F2)14(4-) anions and two types of Ag(I) cations. One particular Ag(II) site present in the crystal structure of Ag9(PO2F2)14 is the first known example of square pyramidal penta-coordinated Ag(ii) in an oxo-ligand environment. Ag(i)PO2F2 - the product of the thermal decomposition of Ag9(PO2F2)14 - has also been characterized by thermal analysis, IR spectroscopy and X-ray powder diffraction. It has a complicated crystal structure as well, which consists of infinite 1D [Ag(I)O4/2] chains which are linked to more complex 3D structures via OPO bridges. The PO2F2(-) anions bind to cations in both compounds as bidentate oxo-ligands. The terminal F atoms tend to point inside the van der Waals cavities in the crystal structure of both compounds. All important structural details of both title compounds were corroborated by DFT calculations.

"This 'telephone' has too many shortcomings to be seriously considered as a means of communication. The device is inherently of no value to us." This was an internal memo written by Western Union in 1876. That's right. Without efficient knowledge sharing and technology transfer, even the best scientific development may prove to be a damp squib for a long time. The Basel Life Science Week was created in order to promote scientific and economic exchange and pave the way for innovative ideas. That's why NTN Swiss Biotech has moved its traditional 'Olten Meeting' to the Basel Life Science Week. It is the ideal setting for NTN Swiss Biotech and the School of Life Sciences FHNW to present innovative developments within its network of academic and industrial partners in the future-oriented disciplines of Molecular Diagnostics and Medicinal Chemistry.

77 FR 52791 - Regulatory Capital Rules: Regulatory Capital, Implementation of Basel III, Minimum Regulatory...

Federal Register 2010, 2011, 2012, 2013, 2014

2012-08-30

...The Office of the Comptroller of the Currency (OCC), Board of Governors of the Federal Reserve System (Board), and the Federal Deposit Insurance Corporation (FDIC) (collectively, the agencies) are seeking comment on three Notices of Proposed Rulemaking (NPR) that would revise and replace the agencies' current capital rules. In this NPR, the agencies are proposing to revise their risk-based and leverage capital requirements consistent with agreements reached by the Basel Committee on Banking Supervision (BCBS) in ``Basel III: A Global Regulatory Framework for More Resilient Banks and Banking Systems'' (Basel III). The proposed revisions would include implementation of a new common equity tier 1 minimum capital requirement, a higher minimum tier 1 capital requirement, and, for banking organizations subject to the advanced approaches capital rules, a supplementary leverage ratio that incorporates a broader set of exposures in the denominator measure. Additionally, consistent with Basel III, the agencies are proposing to apply limits on a banking organization's capital distributions and certain discretionary bonus payments if the banking organization does not hold a specified amount of common equity tier 1 capital in addition to the amount necessary to meet its minimum risk- based capital requirements. This NPR also would establish more conservative standards for including an instrument in regulatory capital. As discussed in the proposal, the revisions set forth in this NPR are consistent with section 171 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act), which requires the agencies to establish minimum risk-based and leverage capital requirements. In connection with the proposed changes to the agencies' capital rules in this NPR, the agencies are also seeking comment on the two related NPRs published elsewhere in today's Federal Register. The two related NPRs are discussed further in the SUPPLEMENTARY INFORMATION.

The study aims to describe the use of dialysis catheters in critically ill patients treated with continuous renal replacement therapy (CRRT) and to study the impact of femoral versus non-femoral access on CRRT dose. Statistical analysis and predictive modelling of data from the Randomized Evaluation of Normal vs. Augmented Level renal replacement therapy trial. The femoral vein was the first access site in 937 (67%) of 1,399 patients. These patients had higher Acute Physiology and Chronic Health Evaluation and Sequential Organ Failure Assessment scores (p = 0.009) and lower pH (p < 0.001) but similar mortality to patients with non-femoral access (44 vs. 45%; p = 0.63). Lower body weight was independently associated with femoral access placement (OR 0.97, 95% CI 0.96-0.98). Femoral access was associated with a 1.03% lower CRRT dose (p = 0.05), but a 4.20% higher dose was achieved with 13.5 Fr catheters (p = 0.03). Femoral access was preferred in lighter and sicker patients. Catheter gauge had greater impact than catheter site in CRRT dose delivery.

2012-02-01

Feral pigeons (Columba livia) are commonly infected with Chlamydia psittaci, the agent of psittacosis in humans. To assess the risk of zoonosis posed by feral pigeons in the urban environment, we determined the prevalence of Chlamydia psittaci by detection of the outer-membrane protein A (ompA) gene of this pathogen in pharyngeal and cloacal samples of 202 feral pigeons present in a loft in Basel, Switzerland. Additionally, we examined 620 fresh faecal droppings of feral pigeons at six public sites in Basel. The ompA gene of C. psittaci could be detected in only 17 (8.4 %) of the 202 feral pigeons in the loft. C. psittaci DNA was present in nine (2.0 %) of 447 of the pharyngeal swabs and 11 (3.2 %) of the 348 cloacal swabs. Genotyping of the ompA gene revealed genotype B in seven of the birds. In one bird, a mixed infection was detected with the genotypes A, B and E/B, which, to our knowledge is the first time such an infection has been reported. Some of these birds immigrated into the loft as adults. To our knowledge, this is the first study to document how the interconnectedness between feral pigeon subpopulations favours the spread of C. psittaci. C. psittaci DNA was not detected in any of the faecal droppings collected at the six public areas. In spite of the low levels of C. psittaci shedding by feral pigeons in Basel, close contact to feral pigeons bears the risk of zoonotic transmission of C. psittaci. Feral pigeon management programmes and public education should be implemented to reduce the risk of a pigeon-to-human transmission of such pathogenic agents.

Upon a first encounter, individuals spontaneously associate faces with certain personality dimensions. Such first impressions can strongly impact judgments and decisions and may prove highly consequential. Researchers investigating the impact of facial information often rely on (a) real photographs that have been selected to vary on the dimension of interest, (b) morphed photographs, or (c) computer-generated faces (avatars). All three approaches have distinct advantages. Here we present the Basel Face Database, which combines these advantages. In particular, the Basel Face Database consists of real photographs that are subtly, but systematically manipulated to show variations in the perception of the Big Two and the Big Five personality dimensions. To this end, the information specific to each psychological dimension is isolated and modeled in new photographs. Two studies serve as systematic validation of the Basel Face Database. The Basel Face Database opens a new pathway for researchers across psychological disciplines to investigate effects of perceived personality. PMID:29590124

Nano-silver and its composite materials are widely used in medicine, food and other industries due to their strong conductivity, size effect and other special performances. So far, more microbial researches have been applied, but a plant method is rarely reported. In order to open up a new way to prepare AgNP composites, pomegranate peel extract was used in this work to reduce Ag+ to prepare Ag/Ag+/Ag3+ nanoparticle composites. UV-Vis was employed to detect and track the reduction of Ag+ and the forming process of AgNPs. The composition, structure and size of the crystal were analyzed by XRD and TEM. Results showed that, under mild conditions, pomegranate peel extract reacted with dilute AgNO3 solution to produce Ag/Ag+/Ag3+ nanoparticle composites. At pH = 8 and 10 mmol/L of AgNO3 concentration, the size of the achieved composites ranged between 15 and 35 nm with spherical shapes and good crystallinity. The bactericidal experiment indicated that the prepared Ag/Ag+/Ag3+ nanoparticles had strong antibacterial activity against gram positive bacteria and gram negative bacteria. FTIR analysis revealed that biological macromolecules with groups of sbnd NH2, sbnd OH, and others were distributed on the surface of the newly synthesized Ag/Ag+/Ag3+ nanoparticles. This provided a useful clue to further study the AgNP biosynthesis mechanism.

The field of speech-language pathology (SLP) in Brazil, named 'fonoaudiologia', comprises both a therapeutic approach to communication disorders and audiology and was officially recognized on December 9, 1981 (law No. 6965). University programs exist since the 1960s. The undergraduate level is a 4-year honors Bachelor of Science program and requires at least a 3,700 h of coursework. Since 1996 four areas of specialization were established: language, audiology, voice and oral myology, requiring a minimum of 500 h of course. Graduate programs in the narrower sense,master's degree and doctorate, exist since the 1970s. Brazil is a 180-million inhabitant country with approximately 25,000 speech-language pathologists, of which 2,700 are specialists, 800 masters and 210 doctors. There are almost 100 undergraduate programs and 70 specialization courses; however, for master's degree and doctorate purposes there are only 8. Copyright (c) 2006 S. Karger AG, Basel.

Dissecting auditory verbal hallucinations into two components: audibility (Gedankenlautwerden) and alienation (thought insertion).

PubMed

Sommer, Iris E; Selten, Jean-Paul; Diederen, Kelly M; Blom, Jan Dirk

2010-01-01

This study proposes a theoretical framework which dissects auditory verbal hallucinations (AVH) into 2 essential components: audibility and alienation. Audibility, the perceptual aspect of AVH, may result from a disinhibition of the auditory cortex in response to self-generated speech. In isolation, this aspect leads to audible thoughts: Gedankenlautwerden. The second component is alienation, which is the failure to recognize the content of AVH as self-generated. This failure may be related to the fact that cerebral activity associated with AVH is predominantly present in the speech production area of the right hemisphere. Since normal inner speech is derived from the left speech area, an aberrant source may lead to confusion about the origin of the language fragments. When alienation is not accompanied by audibility, it will result in the experience of thought insertion. The 2 hypothesized components are illustrated using case vignettes. Copyright 2010 S.

Lyme borreliosis (LB) is the most frequent ixodid tick-borne human disease in the world, with an estimated 85,500 patients annually (underlying data presented in this review: Europe 65,500, North America 16,500, Asia 3,500, North Africa 10; approximate figures). This chapter summarizes the up-to-date knowledge about facts and factors important in the epidemiology of LB all over the world. Individual sections briefly describe geographic (latitudinal and altitudinal) distribution and incidence rates of LB in individual countries; seasonal distribution of the disease; effects of patients' age, sex, and profession; comparison of urban versus rural settings; weather-related effects on LB incidence; risk factors for LB acquisition by humans; and risk assessment. This chapter finishes by recommending a more thorough epidemiological surveillance for LB, including morbidity notification in some additional countries where it has not yet been fully implemented.

There were remarkable achievements in the 19th century in our understanding of the cells of the allergic response, the clear descriptions of hay fever and asthma, as well as the role of pollen in seasonal rhinitis. Although allergy as a concept was not developed until well into the 20th century, the foundations of our present understanding of these diseases were laid in the 1800s. The outstanding physicians and scientists of this time included Paul Ehrlich (who described mast cells, eosinophils and basophils), John Bostock (who provided the first detailed account of hay fever), Charles Blackley (who showed that pollen was the cause of hay fever), Morrill Wyman (who demonstrated that autumnal catarrh was due to ragweed pollen), Henry Hide Salter (who made the first classic description of asthma) and Henri Laënnec (the inventor of the stethoscope). © 2014 S.

To compare the incidence of intraoperative and early postoperative complications (IEPC), visual outcomes, and change in intraocular pressure (IOP) between eyes with and without pseudoexfoliation syndrome (PEX) having cataract extraction by phacoemulsification. 800 eyes with PEX and 1,600 eyes without PEX having cataract extraction by phacoemulsification were included in this retrospective study. Evaluated parameters were incidence of IEPC, visual outcomes and change in IOP. chi2 and Student's t test were used for statistical analysis. There were no significant differences in the incidence of IEPC and visual acuity gain between the two groups (p > 0.05). Rise in IOP in the early postoperative period was significantly higher in the PEX group (p < 0.02). Patients with PEX who have phacoemulsification can achieve results similar to patients without PEX. IOP control in the early postoperative period seems to be more important in patients with PEX. Copyright 2008 S. Karger AG, Basel.

Although alternative medicines are widely used within the general population, the extent of their use within the dialysis population is unknown. It is possible that dialysis patients may be more likely to turn towards alternative therapies in view of the chronicity of their disease. In addition, this particular patient population could be at an increased risk of toxicity from these therapies due to an absence of renal excretion. A detailed assessment of complementary and alternative medicine use in our dialysis patients revealed that 18% of our patients had used or were using some form of alternative medicine therapy. An additional 63% of our patients, however, were willing to use a complementary or alternative medication. Our results suggest that hemodialysis patients are extremely receptive to the use of such therapies and are therefore exposed to all their potential benefit and harm. Copyright 2007 S.

Antibiotics are frequently used to treat hidradenitis suppurativa (HS); however, few data on their efficacy are available. To evaluate the efficacy of a combination of systemic clindamycin (300 mg twice daily) and rifampicin (600 mg daily) in the treatment of patients with severe HS. Patients (n = 116) who received this combination were studied retrospectively. The main outcome measure was the severity of the disease, assessed by the Sartorius score, before and after 10 weeks of treatment. The Sartorius score dramatically improved at the end of treatment (median = 29, interquartile range = 14.5, vs. median = 14.5, interquartile range = 11; p < 0.001), as did other parameters of severity as well as the quality of life score. Eight patients (6.9%) stopped the treatment because of side effects. The combination of clindamycin and rifampicin is effective in the treatment of severe HS. Copyright 2009 S. Karger AG, Basel.

From cheetahs to chimpanzees: a comparative review of the drivers of human-carnivore conflict and human-primate conflict.

2012-01-01

Human-wildlife conflict is a growing conservation threat, and is increasingly of importance to primate conservationists. Despite this, relatively little work has been done to date on the drivers of human-primate conflict, especially compared to other conflict-causing taxa such as large carnivores. However, the drivers of conflict are often very similar across species, so conflict researchers can learn important lessons from work conducted on other taxa. This paper discusses 8 key factors which are likely to affect how hostile people are towards wildlife and any damage they cause--6 of these are common to both carnivores and primates, while one is much more applicable to carnivores and the other is specific to primates. These conflict drivers involve numerous social and cultural factors, and highlight the importance of truly understanding the local drivers of conflict in order to develop effective mitigation strategies.

Berhouma, Moncef; Jemel, Hafedh; Ksira, Iadh; Khaldi, Moncef

2008-01-01

Intracranial teratomas are rare germ cell neoplasms occurring more often during childhood. We report the case of a huge mature teratoma of the pineal region in a 10-year-old patient that was not correctly diagnosed preoperatively by stereotactic biopsy. The tumor was revealed by intracranial hypertension and a Parinaud syndrome. The tumor markers were within normal levels in the serum. A left transcortical parietal approach was used to completely resect the tumor. No adjuvant treatment was given. A complete neurological recovery was observed after the surgical procedure. Follow-up at 2 years did not show any recurrence. Pineal mature teratomas have a good prognosis, in contrast to their immature or mixed counterparts. A rigorous histological examination of the tumor samples is mandatory, in order to not omit a mixed contingent within the tumor. The treatment is exclusively surgical. (c) 2008 S. Karger AG, Basel.

Staphylococcus epidermidis biofilm formation and structural organization on different types of intraocular lenses under in vitro flow conditions.

PubMed

Baillif, Stéphanie; Leduff, Frank; Hartmann, Daniel J; Kodjikian, Laurent

2013-01-01

To compare the adherence and structural organization of Staphylococcus epidermidis biofilm on intraocular lenses (IOLs). IOLs made of 3 different biomaterials [polymethyl methacrylate (PMMA), hydrophilic acrylic or hydrophobic acrylic] were incubated into an S. epidermidis bacterial solution. Scanning electron microscopy was used to count the bound bacteria and to analyze the structural biofilm architecture. After 4-6 h of incubation, adherence was statistically weakest on the hydrophilic acrylic polymer. On the hydrophobic acrylic material, the bacterial cells tended to cover the substratum in a horizontal spread in a continuous monolayer. On the hydrophilic acrylic material or on the PMMA material bacterial cells tended to form only few, small scattered cell clusters. The data suggest that the pattern of S. epidermidis adhesion varies with the IOL biomaterial. Hydrophobic IOLs seem to be more permissive to S. epidermidis adhesion. Copyright © 2013 S.

Does surgical genitoplasty affect gender identity in the intersex infant?

PubMed

Nihoul-Fékété, C

2005-01-01

There is no clear-cut answer to the question of whether surgical genitoplasty affects gender identity in the intersex infant. The debate centres around which is more important for the development of gender identity: the biological sex of a child or the sex in which a child is reared. We believe that the surgical achievement of a phenotype concordant with the sex of rearing is a tremendous help to the parents of an intersex infant. We do not consider that the 'neutral' upbringing of a child with ambiguous genitalia is a feasible option, first because of the parents' distress which prevents them from raising their child normally and second because in most cultures around the world gender variants are not treated as equals. A neutral upbringing may induce psychosocial consequences that are more pernicious than carefully considered neonatal sex attribution and concordant surgical genitoplasty. (c) 2005 S.

Leishmaniasis is caused by a parasite of the Leishmania genus, affecting more than 12 million people in 98 countries. The control of leishmaniasis remains a serious problem. There are currently no vaccines for leishmaniasis. The drugs available are toxic, expensive and frequently ineffective. The in vitro activity of SURFACEN® and SP-A against Leishmania amazonensis was evaluated. The combination of both products resulted in a synergic pharmacology effect, demonstrated by a fractional inhibitory concentration index <0.5. A more effective combination was a SURFACEN/SP-A ratio of 4:1, using a method of fixed ratio. The therapeutic effect of SURFACEN and SP-A as antileishmanial compounds was demonstrated, with a potentiation of activity when they were incubated in conjunction. Our results propose an exploration of these products in order to design new formulations against the Leishmania parasite. © 2014 S. Karger AG, Basel.

A review of Edward Flatau's 1894 Atlas of the Human Brain by the neurologist Sigmund Freud.

PubMed

Triarhou, Lazaros C

2011-01-01

In 1894, the Polish neurologist Edward Flatau (1868-1932), working in Berlin, published an exquisite photographic atlas of the unfixed human brain, preceding by 2 years Das Menschenhirn, the reference work of Gustaf Retzius (1842-1919) in Stockholm. In his early career as a neuroanatomist and neurologist, Sigmund Freud (1856-1939) wrote a review of Flatau's atlas for the Internationale klinische Rundschau, which has not been included in the 'Standard Edition of the Complete Psychological Works'. The aim of the present paper is twofold: to document Freud's review, and to revive the largely forgotten atlas of Flatau. The full text of Freud is presented in translation. Further, one element Flatau, Retzius and Freud had in common is discussed: their early role as protagonists and firm supporters of Ramón y Cajal's neuron theory, the cornerstone of modern neuroscience.

Disorders of Sex Development with Testicular Differentiation in SRY-Negative 46,XX Individuals: Clinical and Genetic Aspects.

PubMed

Grinspon, Romina P; Rey, Rodolfo A

2016-01-01

Virilisation of the XX foetus is the result of androgen excess, resulting most frequently from congenital adrenal hyperplasia in individuals with typical ovarian differentiation. In rare cases, 46,XX gonads may differentiate into testes, a condition known as 46,XX testicular disorders of sex development (DSD), or give rise to the coexistence of ovarian and testicular tissue, a condition known as 46,XX ovotesticular DSD. Testicular tissue differentiation may be due to the translocation of SRY to the X chromosome or an autosome. In the absence of SRY, overexpression of other pro-testis genes, e.g. SOX family genes, or failure of pro-ovarian/anti-testis genes, such as WNT4 and RSPO1, may underlie the development of testicular tissue. Recent experimental and clinical evidence giving insight into SRY-negative 46,XX testicular or ovotesticular DSD is discussed. © 2016 S. Karger AG, Basel.

The intonation of gapping and coordination in Japanese: evidence for intonational phrase and utterance.

PubMed

Kawahara, Shigeto; Shinya, Takahito

2008-01-01

In previous studies of Japanese intonational phonology, levels of prosodic constituents above the Major Phrase have not received much attention. This paper argues that at least two prosodic levels exist above the Major Phrase in Japanese. Through a detailed investigation of the intonation of gapping and coordination in Japanese, we argue that each syntactic clause projects its own Intonational Phrase, while an entire sentence constitutes one Utterance. We show that the Intonational Phrase is characterized by tonal lowering, creakiness and a pause in final position, as well as a distinctive large initial rise and pitch reset at its beginning. The Utterance defines a domain of declination, and it is signaled by an even larger initial rise, as well as a phrasal H tone at its right edge. Building on our empirical findings, we discuss several implications for the theory of intonational phonology. (c) 2007 S. Karger AG, Basel.

Cognitive reserve: implications for assessment and intervention.

PubMed

Stern, Yaakov

2013-01-01

The concept of reserve is used to explain the observation that some individuals function better than others in the presence of brain pathology. This article reviews the concept of reserve from its theoretical basis to the implication of reserve for clinical practice. A distinction between brain reserve, referring to individual differences in the anatomic substrate, and cognitive reserve, referring to differences in the flexibility or adaptivity of cognitive networks, is useful. Epidemiologic evidence indicates that a set of life exposures including higher educational and occupational attainment, and engaging in leisure activities is associated with a lower risk of incident dementia, suggesting that these life exposures may enhance cognitive reserve. This provides a basis for controlled clinical studies that can test specific exposures that may enhance reserve. The concept of cognitive reserve also has important implications for clinical practice in terms of diagnosis and prognosis. © 2013 S. Karger AG, Basel.

Aging and physiological changes of the kidneys including changes in glomerular filtration rate.

PubMed

Musso, Carlos G; Oreopoulos, Dimitrios G

2011-01-01

In addition to the structural changes in the kidney associated with aging, physiological changes in renal function are also found in older adults, such as decreased glomerular filtration rate, vascular dysautonomia, altered tubular handling of creatinine, reduction in sodium reabsorption and potassium secretion, and diminished renal reserve. These alterations make aged individuals susceptible to the development of clinical conditions in response to usual stimuli that would otherwise be compensated for in younger individuals, including acute kidney injury, volume depletion and overload, disorders of serum sodium and potassium concentration, and toxic reactions to water-soluble drugs excreted by the kidneys. Additionally, the preservation with aging of a normal urinalysis, normal serum urea and creatinine values, erythropoietin synthesis, and normal phosphorus, calcium and magnesium tubular handling distinguishes decreased GFR due to normal aging from that due to chronic kidney disease.

After prison release, offenders with heroin use problems are at high risk of relapse and overdose death. There is a particular need for treatments that can be initiated in prison and continued after release into the community. Methadone maintenance treatment has been shown to reduce heroin use, criminality and mortality. Naltrexone implant treatment has not previously been evaluated in prison settings. This study compares the effects of naltrexone implants and methadone treatment on heroin and other illicit drug use, and criminality among heroin-dependent inmates after release from prison. Forty-six volunteers were randomly allocated to naltrexone implants or methadone before release. Intention-to-treat analyses showed reductions in both groups in frequency of use of heroin and benzodiazepines, as well as criminality, 6 months after prison release. Naltrexone implants may be a valuable treatment option in prison settings. 2010 S. Karger AG, Basel.

Do convergent developmental mechanisms underlie convergent phenotypes?

NASA Technical Reports Server (NTRS)

Wray, Gregory A.

2002-01-01

Convergence is a pervasive evolutionary process, affecting many aspects of phenotype and even genotype. Relatively little is known about convergence in developmental processes, however, nor about the degree to which convergence in development underlies convergence in anatomy. A switch in the ecology of sea urchins from feeding to nonfeeding larvae illustrates how convergence in development can be associated with convergence in anatomy. Comparisons to more distantly related taxa, however, suggest that this association may be limited to relatively close phylogenetic comparisons. Similarities in gene expression during development provide another window into the association between convergence in developmental processes and convergence in anatomy. Several well-studied transcription factors exhibit likely cases of convergent gene expression in distantly related animal phyla. Convergence in regulatory gene expression domains is probably more common than generally acknowledged, and can arise for several different reasons. Copyright 2002 S. Karger AG, Basel.

A Phenomenological Approach to Psychopathology of Imagination: Development of a Descriptive Instrument - Examination of Anomalous Fantasy and Imagination.

This paper serves as an introduction to the Examination of Anomalous Fantasy and Imagination (EAFI) - a novel instrument for a semistructured, phenomenological exploration of psychopathology of imagination. We present an account of the phenomenology of imagination and proceed to a presentation of the disorders of imagination that are addressed in the EAFI. Furthermore, the interrater reliability of the EAFI was examined in a diagnostically heterogeneous sample of 20 in-patients. The interrater agreement ranged from 0.6 to 1.0, with an average κ of 0.84. The internal consistency of the EAFI as measured by Cronbach's α was above 0.88. We suggest that the anomalies of imagination explored by the EAFI reflect an alteration of the structure of consciousness and belong to a fundamental, generative layer of psychopathology. These disorders may have relevance for differential diagnostic purposes, especially in first-contact, young patients. © 2018 S. Karger AG, Basel.

The antifungal activity of coriander oil has already been demonstrated in vitro. Evaluation of the efficacy and tolerability of 6% coriander oil in unguentum leniens in the treatment of interdigital tinea pedis. Half-side comparative pilot study on subjects with symmetric, bilateral interdigital tinea pedis. Active drug and placebo control were applied twice daily on the affected areas, and follow-up visits were performed on days 14 and 28. 40 participants (mean age 52.5 years, 60% male) were included in the study. For 6% coriander oil in unguentum leniens, a highly significant improvement of the clinical signs (p < 0.0001) was observed during the entire observation period; the number of positive fungal cultures also tended to decrease (p = 0.0654). The tolerability of the tested substances was good. Coriander oil is effective and well tolerated in the treatment of interdigital tinea pedis. Copyright © 2013 S. Karger AG, Basel.

Assessment of the Utility of Cytology and Flow Cytometry of Cerebrospinal Fluid Samples in Clinical Practice.

Nam, Anna S; Giorgadze, Tamara; Tam, Wayne; Chadburn, Amy

2018-01-01

We sought to assess the utility and limitations of both flow cytometry (FC) and cytology for the analysis of cerebrospinal fluid (CSF) in a practical clinical setting. A total of 393 consecutive CSF samples from 171 patients submitted for both cytomorphologic and FC assessments were analyzed. Both FC and cytology findings were negative for malignancy in 315/393 samples (80%), and either positive (POS) or suspicious/atypical (SUSP/AT) in 7% of samples. This resulted in high agreement between FC and cytology (87%). Minor discrepancies were present in 4% of the cases. In 28 samples, an abnormal population was detected by FC but not by cytology. FC and cytology are important complementary methods for analyzing CSF samples. In cases where cytology is SUSP/AT and FC is inconclusive or negative, additional specimens should be submitted for immunostaining, cytogenetics, and/or molecular studies. © 2018 S.

To improve our knowledge of the distribution of the critically endangered greater bamboo lemur Prolemur simus, we surveyed 6 sites in eastern Madagascar. We found its characteristic feeding signs at 5 sites and made a direct sighting at one of these. One site represents a northern extension of 45 km of the known extant range of the species. Two sites are located in a forest corridor approximately halfway between the previously known southern and northern populations, therefore suggesting a broadly continuous distribution of the species within its range rather than the previously suspected distribution of two distinct populations separated by a distance of over 200 km. Our results illustrate the benefit of species-focussed surveys in determining the true distribution of endangered species, a realistic measure which is necessary in order to assess their current status and to prioritise long-term conservation interventions.

Induced pluripotent stem cells (iPSCs) are generated by reprogramming human somatic cells through the overexpression of four transcription factors: Oct4, Sox2, Klf4 and c-Myc. iPSCs are capable of indefinite self-renewal, and they can differentiate into almost any type of cell in the body. These cells therefore offer a highly valuable therapeutic strategy for tissue repair and regeneration. Recent experimental and preclinical research has revealed their potential for cardiovascular disease diagnosis, drug screening and cellular replacement therapy. Nevertheless, significant challenges remain in terms of the development and clinical application of human iPSCs. Here, we review current progress in research related to patient-specific iPSCs for ex vivo modeling of cardiovascular disorders and drug screening, and explore the potential of human iPSCs for use in the field of cardiovascular regenerative medicine. © 2015 S.

[On the relationship of psychosomatic and mind-body medicine: integrative, complementary or alternative disciplines within an evolutionary approach?].

PubMed

Brunnhuber, Stefan; Michalsen, Andreas

2012-01-01

The text outlines the relation between psychosomatic medicine as an established medical discipline and the emerging concept of mind-body medicine from a historical, clinical and epistemological perspective. Limitations and contributions of both disciplines are discussed and the opportunities within the concept of Integrative Medicine are outlined. Whereas psychosomatic medicine is perceived as a form of transformation through a primarily verbal discoursive relationship, mind-body medicine claims healing through increased traditional techniques of the relaxation response, increased awareness, mindfulness, increasing des-identification and health-promoting lifestyle modification. It becomes clear that mind-body medicine seems to be epistemologically the broader theoretical framework, whereas in a clinical context the combination of both disciplines appears to be complementary and synergistic. The connection between psychosomatic medicine and mind-body medicine can make an important and exemplary contribution to the concept of Integrative Medicine. Copyright © 2012 S. Karger AG, Basel.

Rise to power: a case study of male fecal androgen and cortisol levels before and after a non-aggressive rank change in a group of wild white-faced capuchins (Cebus capucinus).

We examined fecal androgen and cortisol levels in three adult male white-faced capuchin monkeys (Cebus capucinus) before and after a non-aggressive rank increase in one habituated group residing in the Santa Rosa Sector of the Área de Conservación Guanacaste, Costa Rica. Fecal samples (n = 116) were collected opportunistically between July 2006 and July 2007. Alpha males had higher mean androgen levels than subordinates, and acquisition of the alpha position was linked to an immediate increase in mean androgens. Cortisol levels also increased in the alpha male after acquisition of his new rank, though this increase was delayed relative to the change in rank. These results indicate that, during a non-aggressive rank change, androgen and cortisol levels in male white-faced capuchins are physiological responses to dominance rank, rather than precursors that facilitate rank acquisition.

To assess interactions between retigabine and levetiracetam in suppressing maximal electroshock-induced tonic seizures in Albino Swiss mice, type II isobolographic analysis was used. Total brain antiepileptic drug concentrations were measured with high pressure liquid chromatography. The combinations of retigabine with levetiracetam at the fixed-ratios of 1:5 and 1:10 were supra-additive (synergistic; p < 0.05) in terms of seizure suppression, while the combinations at the fixed-ratios of 1:1 and 1:2 were additive. No pharmacokinetic changes in total brain concentrations of levetiracetam and retigabine were documented, indicating the pharmacodynamic nature of interaction between these antiepileptic drugs in the mouse maximal electroshock-induced tonic seizure model. The combination of retigabine with levetiracetam at the fixed-ratios of 1:5 and 1:10 appears to be particularly beneficial combination exerting supra-additive interaction in suppressing maximal electroshock-induced tonic seizures. © 2015 S.
